PMID- 29443383 TI - A B3GALT6 variant in patient originally described as Al-Gazali syndrome and implicating the endoplasmic reticulum quality control in the mechanism of some beta3GalT6-pathy mutations. AB - Al-Gazali syndrome encompasses several clinical features including prenatal growth retardation, large joints contractures with camptodactyly, bilateral talipes equinovarus, small mouth, anterior segment anomalies of the eyes, and early lethality. Recently, a baby with features very similar to Al-Gazali syndrome was found to have compound heterozygous variants in B3GALT6. This gene encodes Beta-1,3-galactosyltransferase 6 (beta3GalT6), an essential component of the glycosaminoglycan synthesis pathway. Pathogenic variants in B3GALT6 have also been shown to cause Ehlers-Danlos syndrome spondylodysplastic type (spEDS B3GALT6) and spondyloepimetaphyseal dysplasia with joint laxity type I (SEMD JL1). In 2017, a new international classification of EDS included these 2 conditions together with the child reported to have features similar to Al-Gazali syndrome under spondylodysplastic EDS (spEDS). We report a disease-causing variant c.618C > G, p.(Cys206Trp) in 1 patient originally described as Al-Gazali syndrome and reported in 1999. We evaluated the involvement of the endoplasmic reticulum-associated protein degradation, in the pathogenesis of 13 B3GALT6 variants. Retention in endoplasmic reticulum was evident in 6 of them while the c.618C > G, p.(Cys206Trp) and the other 6 variants trafficked normally. Our findings confirm the involvement of B3GALT6 in the pathogenesis of Al-Gazali syndrome and suggest that Al-Gazali syndrome represents the severe end of the spectrum of the phenotypes caused by pathogenic variants in this gene.

PMID- 29443387 TI - Predictors of early left ventricular systolic dysfunction in duchenne muscular dystrophy patients. AB - INTRODUCTION: Early detection of left ventricular systolic dysfunction (LVSD) is important for therapeutic strategies for Duchenne muscular dystrophy (DMD) patients. We analyzed myocardial strain using echocardiography for early detection of LVSD and determined the predictors of early LVSD. METHODS: This investigation was a cross-sectional study of 40 DMD patients with normal left ventricular ejection fraction. Global longitudinal strain (GLS) was used to analyze subtle disturbances in longitudinal contraction of the myocardium. Patients were determined to have early LVSD (GLS > -18) or normal left ventricular systolic function (GLS <= -18). RESULTS: Patients who had early LVSD were older and had a higher frequency of corticosteroid therapy and of mutations in exons 45, 46, 47, 48, 49, 50, and 52. DISCUSSION: Myocardial strain measurements are useful for the early diagnosis of LVSD in DMD patients. Older age, use of corticosteroids, and mutations within the "hot-spot" region of the DMD gene are associated with early LVSD. Muscle Nerve, 2018. PMID- 29443386 TI - Technical Note: Error metrics for estimating the accuracy of needle/instrument placement during transperineal magnetic resonance/ultrasound-guided prostate interventions. AB - PURPOSE: Image-guided systems that fuse magnetic resonance imaging (MRI) with three-dimensional (3D) ultrasound (US) images for performing targeted prostate needle biopsy and minimally invasive treatments for prostate cancer are of increasing clinical interest. To date, a wide range of different accuracy estimation procedures and error metrics have been reported, which makes comparing the performance of different systems difficult. METHODS: A set of nine measures are presented to assess the accuracy of MRI-US image registration, needle positioning, needle guidance, and overall system error, with the aim of providing a methodology for estimating the accuracy of instrument placement using a MR/US guided transperineal approach. RESULTS: Using the SmartTarget fusion system, an MRI-US image alignment error was determined to be 2.0 +/- 1.0 mm (mean +/- SD), and an overall system instrument targeting error of 3.0 +/- 1.2 mm. Three needle deployments for each target phantom lesion was found to result in a 100% lesion hit rate and a median predicted cancer core length of 5.2 mm. CONCLUSIONS: The application of a comprehensive, unbiased validation assessment for MR/US guided systems can provide useful information on system performance for quality assurance and system comparison. Furthermore, such an analysis can be helpful in identifying relationships between these errors, providing insight into the technical behavior of these systems.

AB - PURPOSE: Texture analysis is an emerging tool in the field of medical imaging analysis. However, many issues have been raised in terms of its use in assessing patient images and it is crucial to harmonize and standardize this new imaging measurement tool. This study was designed to evaluate the reliability of texture indices of CT images on a phantom including a reproducibility study, to assess the discriminatory capacity of indices potentially relevant in CT medical images and to determine their redundancy. METHODS: For the reproducibility and discriminatory analysis, eight identical CT acquisitions were performed on a phantom including one homogeneous insert and two close heterogeneous inserts. Texture indices were selected for their high reproducibility and capability of discriminating different textures. For the redundancy analysis, 39 acquisitions of the same phantom were performed using varying acquisition parameters and a correlation matrix was used to explore the 2 * 2 relationships. LIFEx software was used to explore 34 different parameters including first order and texture indices. RESULTS: Only eight indices of 34 exhibited high reproducibility and discriminated textures from each other. Skewness and kurtosis from histogram were independent from the six other indices but were intercorrelated, the other six indices correlated in diverse degrees (entropy, dissimilarity, and contrast of the co-occurrence matrix, contrast of the Neighborhood Gray Level difference matrix, SZE, ZLNU of the Gray-Level Size Zone Matrix). CONCLUSIONS: Care should be taken when using texture analysis as a tool to characterize CT images because changes in quantitation may be primarily due to internal variability rather than from real physio-pathological effects. Some textural indices appear to be sufficiently reliable and capable to discriminate close textures on CT images. PMID- 29443390 TI - Tolerance limits and methodologies for IMRT measurement-based verification QA: Recommendations of AAPM Task Group No. 218. AB - PURPOSE: Patient-specific IMRT QA measurements are important components of processes designed to identify discrepancies between calculated and delivered radiation doses. Discrepancy tolerance limits are neither well defined nor consistently applied across centers. The AAPM TG-218 report provides a comprehensive review aimed at improving the understanding and consistency of these processes as well as recommendations for methodologies and tolerance limits in patient-specific IMRT QA. METHODS: The performance of the dose difference/distance-to-agreement (DTA) and gamma dose distribution comparison metrics are investigated. Measurement methods are reviewed and followed by a discussion of the pros and cons of each. Methodologies for absolute dose verification are discussed and new IMRT QA verification tools are presented. Literature on the expected or achievable agreement between measurements and calculations for different types of planning and delivery systems are reviewed and analyzed. Tests of vendor implementations of the gamma verification algorithm employing benchmark cases are presented. RESULTS: Operational shortcomings that can reduce the gamma tool accuracy and subsequent effectiveness for IMRT QA are described. Practical considerations including spatial resolution, normalization, dose threshold, and data interpretation are discussed. Published data on IMRT QA and the clinical experience of the group members are used to develop guidelines and recommendations on tolerance and action limits for IMRT QA. Steps to check failed IMRT QA plans are outlined. CONCLUSION: Recommendations on delivery methods, data interpretation, dose normalization, the use of gamma analysis routines and choice of tolerance limits for IMRT QA are made with focus on detecting differences between calculated and measured doses via the use of robust analysis methods and an in-depth understanding of IMRT verification metrics. The recommendations are intended to improve the IMRT QA process and establish consistent, and comparable IMRT QA criteria among institutions. PMID- 29443391 TI - Human papillomavirus genome integration in squamous carcinogenesis: what have next-generation sequencing studies taught us? AB - Human papillomavirus (HPV) infection is associated with ~5% of all human cancers, including a range of squamous cell carcinomas. Persistent infection by high-risk HPVs (HRHPVs) is associated with the integration of virus genomes (which are usually stably maintained as extrachromosomal episomes) into host chromosomes. Although HRHPV integration rates differ across human sites of infection, this process appears to be an important event in HPV-associated neoplastic progression, leading to deregulation of virus oncogene expression, host gene expression modulation, and further genomic instability. However, the mechanisms by which HRHPV integration occur and by which the subsequent gene expression changes take place are incompletely understood. The advent of next-generation sequencing (NGS) of both RNA and DNA has allowed powerful interrogation of the association of HRHPVs with human disease, including precise determination of the sites of integration and the genomic rearrangements at integration loci. In turn, these data have indicated that integration occurs through two main mechanisms: looping integration and direct insertion. Improved understanding of integration sites is allowing further investigation of the factors that provide a competitive advantage to some integrants during disease progression. Furthermore, advanced approaches to the generation of genome-wide samples have given novel insights into the three-dimensional interactions within the nucleus, which could act as another layer of epigenetic control of both virus and host transcription. It is hoped that further advances in NGS techniques and analysis will not only allow the examination of further unanswered questions regarding HPV infection, but also direct new approaches to treating HPV-associated human disease.

PMID- 29443392 TI - Spatial aspects of oncogenic signalling determine the response to combination therapy in slice explants from Kras-driven lung tumours. AB - A key question in precision medicine is how functional heterogeneity in solid tumours informs therapeutic sensitivity. We demonstrate that spatial characteristics of oncogenic signalling and therapy response can be modelled in precision-cut slices from Kras-driven non-small-cell lung cancer with varying histopathologies. Unexpectedly, profiling of in situ tumours demonstrated that signalling stratifies mostly according to histopathology, showing enhanced AKT and SRC activity in adenosquamous carcinoma, and mitogen-activated protein kinase (MAPK) activity in adenocarcinoma. In addition, high intertumour and intratumour variability was detected, particularly of MAPK and mammalian target of rapamycin (mTOR) complex 1 activity. Using short-term treatment of slice explants, we showed that cytotoxic responses to combination MAPK and phosphoinositide 3-kinase mTOR inhibition correlate with the spatially defined activities of both pathways. Thus, whereas genetic drivers determine histopathology spectra, histopathology associated and spatially variable signalling activities determine drug sensitivity. Our study is in support of spatial aspects of signalling heterogeneity being considered in clinical diagnostic settings, particularly to guide the selection of drug combinations.

PMID- 29443393 TI - Parenteral Nutrition Electrolyte Abnormalities and Associated Factors Before and After Nutrition Support Team Initiation. AB - BACKGROUND: Studied since the 1940s, refeeding syndrome still has no universal definition, thus making comparison of studies difficult. Negative outcomes (eg, metabolic abnormalities) may occur with the use of specialized nutrition, such as parenteral nutrition (PN). Less than half of medical institutions have a nutrition support team (NST) managing PN. Interdisciplinary team management of PN may reduce negative outcomes of PN. The objective of this study was to show the value of the NST by measuring differences in PN variables, especially electrolyte abnormalities (EAs), before and after NST initiation at a large medical center and to identify factors associated with EAs among adult subjects receiving PN. MATERIALS AND METHODS: During this retrospective study, computerized medical charts (N = 735) from 2007-2010 were reviewed for electrolyte changes (particularly potassium, magnesium, and phosphorus) the first 3 days following PN initiation in hospitalized adults. Changes in EAs with other variables were compared before and after NST implementation. Equivalent samples sizes were collected to better evaluate the impact of the team. RESULTS: Following the implementation of the NST, fewer EAs were seen in PN patients (53%; chi2 = 10.906, P = .004); significantly less potassium, phosphorus, and magnesium intravenous piggyback supplementation (88.8% vs 94%; chi2 = 5.05, P = .026) was used; and mortality within 30 days of PN cessation was significantly less (12.7% vs 10.6%, P = .012). CONCLUSION: Our study complements existing research, finding that an NST was associated with a decreased occurrence of EAs and mortality in the hospitalized adult receiving PN. PMID- 29443394 TI - Catheter-Related Bloodstream Infections in Adults Receiving Home Parenteral Nutrition: Substantial Differences in Incidence Comparing a Strict Microbiological to a Clinically Based Diagnosis. AB - BACKGROUND: A common complication in patients receiving home parenteral nutrition (HPN) is catheter-related bloodstream infections (CRBSIs). The CRBSI incidence has been advocated as an outcome parameter assessing the quality of care. This study aimed to illustrate how the use of different CRBSI definitions affects the reported incidence. MATERIALS AND METHODS: In an observational study based on the Copenhagen intestinal failure database, all clinically reported CRBSIs from 2002 2013 were compared with data from the affiliated microbiological database according to recommended CRBSI criteria. RESULTS: Clinically, 1034 CRBSIs were observed in 548 adults receiving HPN for 1410 catheter-years. Thus, the clinically assessed CRBSI incidence was 1.95/1000 catheter-days. However, based on the microbiological evaluation, only 47% of our episodes fulfilled the Centers for Disease Control and Prevention (CDC) and European Society for Clinical Nutrition (ESPEN) CRBSI criteria. Employing a catheter-salvaging strategy, 40% of the CRBSI diagnoses were supported by the paired blood culture positivity criteria and only 6% by a positive catheter tip. In 53%, CRBSIs were categorized as a clinical or "probable CRBSI" diagnosis. In 20% of all episodes, missing information/blood cultures hampered a CDC/ESPEN CRBSI diagnosis. Thereby, according to CDC/ESPEN CRBSI definitions, the incidence was 0.92/1000 days or 46% lower than clinically assessed. CONCLUSION: This study illustrates the practical and methodological challenges and great variability in reporting of the CRBSI incidence. Nonetheless, it is recommended as a marker of the quality of care. Consensus regarding CRBSI definitions is a prerequisite for a meaningful comparison of this important outcome parameter between HPN centers. PMID- 29443395 TI - Subcutaneous Infusion of Fluids for Hydration or Nutrition: A Review. AB - Subcutaneous infusion, or hypodermoclysis, is a technique whereby fluids are infused into the subcutaneous space via small-gauge needles that are typically inserted into the thighs, abdomen, back, or arms. In this review, we provide an overview of the technique, summarize findings from studies that have examined the use of subcutaneous infusion of fluids for hydration or nutrition, and describe the indications, advantages, and disadvantages of subcutaneous infusion. Taken together, the available evidence suggests that, when indicated, subcutaneous infusion can be effective for administering fluids for hydration or nutrition, with minimal complications, and has similar effectiveness and safety to the intravenous route. Of note, subcutaneous infusion offers several advantages over intravenous infusion, including ease of application, low cost, and the lack of potential serious complications, particularly infections. Subcutaneous infusion may be particularly suited for patients with mild to moderate dehydration or malnutrition when oral/enteral intake is insufficient; when placement of an intravenous catheter is not possible, tolerated, or desirable; at risk of dehydration when oral intake is not tolerated; as a bridging technique in case of difficult intravenous access or catheter-related bloodstream infection while infection control treatment is being attempted; and in multiple settings (eg, emergency department, hospital, outpatient clinic, nursing home, long-term care, hospice, and home).

PMID- 29443397 TI - Whole Body Protein Turnover and Net Protein Balance After Pediatric Thoracic Surgery: A Noninvasive Single-Dose 15 N Glycine Stable Isotope Protocol With End Product Enrichment. AB - BACKGROUND: We used the 15 N glycine urinary end-product enrichment technique to quantify whole body protein turnover following thoracic surgery. MATERIALS AND METHODS: A single dose of 15 N glycine (2 mg/kg) was administered orally on postoperative day 1 to children (1-18 years) following thoracic surgery. 15 N enrichment of ammonia and urea was measured in mixed urine after 12 and 24 hours, respectively, and protein synthesis, breakdown, and net balance determined. Nitrogen balance (dietary intake minus urinary excretion) was calculated. Urinary 3-methylhistidine:creatinine ratio was measured as a marker of skeletal muscle protein breakdown. RESULTS: We enrolled 19 subjects-median (interquartile range): age, 13.8 years (12.2-15.1); weight, 49.2 kg (38.4-60.8)-who underwent thoracotomy (n = 12) or thoracoscopic (n = 7) surgery. Protein synthesis and breakdown by 15 N enrichment were 7.1 (5.5-9) and 7.1 (5.6-9) g.kg-1 .d-1 with ammonia (12 hours) as the end product, and 5.8 (3.8-6.7) and 6.7 (4.5-7.6) with urea (24 hours), respectively. Net protein balance by the 15 N glycine and urinary urea nitrogen methods were -0.34 (-0.47, -0.3) and -0.48 (-0.65, -0.28) g.kg-1 .d-1 , respectively (rs = 0.828, P < .001). Postoperative change in 3 methylhistidine:creatinine ratio did not correlate significantly with protein breakdown or balance. CONCLUSION: The single-dose oral administration of 15 N glycine stable isotope with measurement of urinary end-product enrichment is a feasible and noninvasive method to investigate whole body protein turnover in children. After major surgery, children manifest increased protein turnover and net negative balance due to increased protein breakdown. PMID- 29443398 TI - JPEN Journal Club 32. Adjusting for Confounding. PMID- 29443399 TI - Two-Year Neurodevelopment and Growth Outcomes for Preterm Neonates Who Received Low-Dose Intravenous Soybean Oil. AB - BACKGROUND: In some studies, the dose of intravenous soybean oil (SO) has been associated with a decreased incidence of intestinal failure-associated liver disease. The effect of lipid sparing on neurodevelopment (ND) and growth remains unknown. This study investigated the impact of SO dose on ND and growth over the first 2 years of age in preterm neonates. MATERIALS AND METHODS: This is a single site prospective follow-up study. Neonates with a gestational age <=29 weeks were randomized to low-dose (LOW) or standard-dose (CON) SO. Bayley Scales of Infant Development III and anthropometric measurements were collected at approximately 6, 12, and 24 months corrected gestational age. RESULTS: Subjects were premature, with a mean (+/-SD) gestational age of 28 +/- 1 and 27 +/- 1 weeks (P = .3) for LOW and CON, respectively. Thirty subjects completed follow-up (LOW = 15, CON = 15). There were no differences for ND and growth outcomes when LOW was compared with CON, with the exception of a higher 12-month follow-up cognitive scaled score in the LOW group (P = .02). CONCLUSION: A reduced SO dose did not adversely affect ND or growth in this cohort of preterm neonates. However, larger studies are needed to determine the long-term safety of SO dose reduction before this strategy can be adopted. PMID- 29443400 TI - Barriers to Nutrition Intervention for Patients With a Traumatic Brain Injury: Views and Attitudes of Medical and Nursing Practitioners in the Acute Care Setting. AB - BACKGROUND: Nutrition delivered to patients with a traumatic brain injury (TBI) is typically below prescribed amounts. While the dietitian plays an important role in the assessment and provision of nutrition needs, they are part of a multidisciplinary team. The views and attitudes of medical and nursing practitioners are likely to be crucial to implementation of nutrition to patients with TBI, but there is limited information describing these. METHODS: A qualitative exploratory approach was used to explore the views and attitudes of medical and nursing practitioners on nutrition for patients with TBI. Participants at 2 major neurotrauma hospitals in Australia completed individual semi-structured interviews with a set of questions and a case study. Interviews were transcribed and coded for themes. RESULTS: Thirty-four health practitioners participated: 18 nurses and 16 physicians. Three major themes emerged: (1) nutrition practices over the hospital admission reflect the recovery course, (2) there are competing priorities when caring for patients with TBI, and (3) the implementation of nutrition therapy is influenced by practitioner roles and expectations. CONCLUSION: Use of qualitative inquiry in the study of attitudes toward nutrition provision to patients with TBI provided detailed insights into the challenges of operationalizing nutrition therapy. These insights can be used to clarify communication between health practitioners working with patients with TBI across the continuum of care. PMID- 29443401 TI - Pediatric Intestinal Failure-Associated Liver Disease: Challenges in Identifying Clinically Relevant Biomarkers. AB - BACKGROUND: Intestinal failure-associated liver disease (IFALD) is complex and diagnosed by concurrent use of parenteral nutrition, clinical presentation, and alterations in hepatic biomarkers exclusive of other causes of liver disease. In comparison with individual measures, composite biomarkers may provide a more effective means for assessing disease progression and response to treatment than single parameters. Since IFALD is considered by some to be a type of drug-induced liver injury (DILI), those diagnostic criteria could potentially be used in this population. Using a preexisting database of children treated for IFALD, our aim was to determine if a similar composite biomarker could be applied to this population. STUDY DESIGN: Adult DILI criteria were applied at baseline, when treatment for IFALD (ie, direct bilirubin >=2.0 mg/dL) was initiated. RESULTS: A total of 214 patients with IFALD treated at Boston Children's Hospital were identified; 168 patients were eligible for analysis. Most patients analyzed were male (61%) and preterm (87%). Alkaline phosphatase (ALP) >=2* upper limit of normal (ULN) captured the least amount of DILI (11%), while gamma glutamyltransferase (GGT) >=1* ULN accounted for the most (62%). Using adult DILI criteria, 60 (39%) patients with IFALD were found to have DILI. Substituting GGT >=1* ULN for ALP >=2* ULN improved the sensitivity, with 105 (69%) of patients meeting at least 1 criterion for DILI. CONCLUSION: Numerous challenges made it difficult to apply the DILI criteria to children with IFALD. Direct bilirubin, fractionated ALP, and perhaps GGT may be more suitable. Given its complex etiology and the age-based differences due to hepatic immaturity and growth, a more suitable composite marker needs to be developed to assess IFALD in this population.

PMID- 29443404 TI - New, Immunomodulatory, Oral Nutrition Formula for Use Prior to Surgery in Patients With Head and Neck Cancer: An Exploratory Study. AB - BACKGROUND: The perioperative use of immunomodulatory nutrition formulas in patients with head and neck cancer reduces the number of postoperative infections and the length of hospital stay. OBJECTIVE: An exploratory, randomized, controlled, blind, clinical trial was designed to examine the effect of the preoperative consumption of a new, immunomodulatory, oral nutrition formula in patients with head and neck cancer. METHODS: Thirty-eight patients were randomized to receive either 400 mL/d of either the new immunomodulatory formula (IF) or that commonly used in clinical practice (CF) over 10 days prior to surgery. Thirty-three patients completed the study. Compliance, tolerance, the length of hospital stay, the incidence of infections and noninfectious complications before discharge, and the same up to 15 and 30 days after discharge were recorded. RESULTS: The percentage of patients who developed infections before discharge was significantly lower in the IF than in the CF group (P = .013), as was the number of infections/100 patients/d (P = .035). The length of hospital stay was significantly shorter in the IF group (P = .001). Both formulas were safe and well tolerated. No other differences were detected. These results suggest preoperative consumption of the new formula to be beneficial for patients with neck and head cancer. Further trials are needed to confirm these results and to test the efficacy of the formula in patients with other conditions. CONCLUSION: The new formula can be safely prescribed as part of the preoperative treatment of patients with head and neck cancer and might reduce the problem of postoperative infection. PMID- 29443405 TI - Vascular access considerations for extracorporeal photopheresis. AB - Extracorporeal photopheresis is an immunomodulatory therapy indicated for patients with cutaneous T-cell lymphoma, graft-versus-host disease, and heart or lung allograft rejection. Whole blood from the patient is drawn into the photopheresis instrument where it is separated into its components. Plasma, red blood cells, and the treated buffy coat are subsequently returned to the patient. Consistent, adequate blood flow is necessary to successfully complete the procedure. Vascular access options for photopheresis include peripheral vein cannulation, tunneled central venous catheters, and subcutaneous ports. Photopheresis is a very safe procedure; however, the complications and impact on the patient's quality of life associated with vascular access devices can be significant. PMID- 29443406 TI - Implantable vascular access devices - past, present, and future. PMID- 29443407 TI - Implanted vascular access device options: a focused review on safety and outcomes. AB - Implantable vascular access devices are frequently used in patients who have poor peripheral venous access. These devices can be partially implanted as tunneled and nontunneled central catheters, or they can be fully implanted as ports. Compared with long-term catheters, implanted ports have lower infection rates and improved perceptions of quality of life, but complications still occur in 2% to 18% of patients, frequently requiring removal of the device. Since the conception of implantable vascular access device ports, numerous advances in port design, materials, and techniques for implantation and care have been developed with the goal of overcoming frequent complications. We review the evidence related to these advances and their effect on the safety profile and complications of implantable vascular access device ports. PMID- 29443408 TI - Vascular access for red blood cell exchange. AB - Red blood cell exchange is the process of removing red blood cells from a patient and replacing them with donated blood using either automated or manual techniques. Red blood cell exchange is a well-recognized and effective therapy for many red blood cell-related diseases, especially sickle cell disease. However, decisions regarding the best methods for vascular access are not intuitive and must account for the patient's clinical condition, complication risks, and lifestyle, especially in the context of long-term vascular access. In this review, we discuss the recognized indications for red blood cell exchange, considerations for the selection of exchange modality and vascular access, and recommendations for the appropriate care and prevention of risks associated with vascular access. PMID- 29443403 TI - Proceedings of the 2017 ASPEN Research Workshop-Gastric Bypass: Role of the Gut. AB - The goal of the National Institutes of Health-funded American Society for Parenteral and Enteral Nutrition 2017 research workshop (RW) "Gastric Bypass: Role of the Gut" was to focus on the exciting research evaluating gut-derived signals in modulating outcomes after bariatric surgery. Although gastric bypass surgery has undoubted positive effects, the mechanistic basis of improved outcomes cannot be solely explained by caloric restriction. Emerging data suggest that bile acid metabolic pathways, luminal contents, energy balance, gut mucosal integrity, as well as the gut microbiota are significantly modulated after bariatric surgery and may be responsible for the variable outcomes, each of which was rigorously evaluated. The RW served as a timely and novel academic meeting that brought together clinicians and researchers across the scientific spectrum, fostering a unique venue for interdisciplinary collaboration among investigators. It promoted engaging discussion and evolution of new research hypotheses and ideas, driving the development of novel ameliorative, therapeutic, and nonsurgical interventions targeting obesity and its comorbidities. Importantly, a critical evaluation of the current knowledge regarding gut-modulated signaling after bariatric surgery, potential pitfalls, and lacunae were thoroughly addressed. PMID- 29443409 TI - Cellular collection by apheresis. AB - Cellular collection is an important and increasingly used apheresis procedure. These collections are performed by leukocytapheresis, a procedure involving the removal of a patient's or donor's white blood cells, and are used to collect hematopoietic progenitor cells, specific cell populations (such as T lymphocytes), and granulocytes. Hematopoietic progenitor cell apheresis and T lymphocyte collection are performed by procedures that enrich for mononuclear cells. Hematopoietic progenitor cells are used for autologous and allogeneic hematopoietic stem cell transplantation, whereas T-cell collection is being used increasingly in novel cellular therapy approaches and for donor lymphocyte infusions to induce graft-versus-leukemia effect. Granulocytes are collected from healthy donors to treat severe sepsis in patients who are refractory to antimicrobial therapies. Less frequently, cellular depletion of leukocytes may be indicated in leukemic patients who have severe hyperleukocytosis resulting in leukoaggregation and decreased tissue perfusion. In these procedures, establishing and maintaining adequate vascular access are critical prerequisites to ensuring a successful procedure. For most types of leukocytapheresis procedures, efforts should be made to ensure that they are performed using peripheral veins, and the use of an intravascular access device should be considered only after it is determined that peripheral access is not feasible or desirable. However, in some settings (such as in patients undergoing autologous hematopoietic stem cell transplantation), intravascular access devices are often used to facilitate both the leukocytapheresis procedure and the subsequent transplant. Here, different types of vascular access approaches used in cellular collections are discussed, and this information is supplemented by the author's experience and practice in areas where published information is limited. PMID- 29443410 TI - A tale of two ports: an in vitro comparison of flow characteristics for therapeutic plasma exchange. AB - Tunneled central venous catheters with ports are increasingly used for therapeutic apheresis procedures. Vortex ports have been used as access for therapeutic apheresis procedures, but are not ideal for therapeutic plasma exchange (TPE) procedures due to lower flow rates. We performed an in vitro experiment to compare flow characteristics of the single-lumen Vortex port (AngioDynamics) with the single-lumen TidalPort (Norfolk Medical). We used expired red blood cell units and adjusted the hematocrit to 40% with normal saline in a 2-L bag. We programmed the Spectra Optia (Terumo BCT) to run a 1.0 volume TPE with 5% albumin as replacement fluid. The TidalPort achieved flow rates of up to 110 mL/min without triggering alarms. Due to crucial alarms, the Vortex Port was not able to run at a flow rate higher than 90 mL/min, and multiple caution alarms were triggered at flow rates of 80 to 90 mL/min. These findings suggest that the TidalPort may be a suitable access option that provides flow rates similar to peripheral or central venous catheters for TPE procedures. PMID- 29443411 TI - Intravascular access devices from an interventional radiology perspective: indications, implantation techniques, and optimizing patency. AB - Central venous access has become invaluable in the treatment of patients with a wide array of acute and chronic disease entities. Central venous catheters provide durable, short-term and long-term access solutions while saving the patient from repeated peripheral needle sticks. Central venous catheters include: non-tunneled central venous catheters, tunneled central venous catheters, and port catheters. Typically, the placement of a central venous catheter is performed by Vascular and Interventional Radiologists. The purpose of this article is to familiarize the reader with the role of Interventional Radiology in the placement and management of intravascular or implantable access devices, with a focus on discussing indications for central venous catheter placement, implantation techniques, potential complications, and management of catheter dysfunction. PMID- 29443412 TI - An ex vivo comparison of vascular access devices used in extracorporeal photopheresis. AB - BACKGROUND: Central venous access devices are commonly used in extracorporeal photopheresis, but their performance has not been systematically evaluated. The primary objective of this study was to compare pressures at various flow rates for central venous access devices in an ex vivo simulation of photopheresis. STUDY DESIGN AND METHODS: Diluted, heparinized red blood cells were circulated through central access devices in series with a photopheresis system, and pressures at several flow rates were recorded. The devices tested were the Trifusion catheter (Hickman), the Vortex single-lumen and dual-lumen ports (Angiodynamics), and the TidalPort device (Norfolk). Flow rates were also compared for silicone and polyurethane catheters and for different catheter internal diameters. RESULTS: The Vortex dual-lumen port generated pressure alarms above flow rates of 60 mL/minute. Throughout flow rates from 5 to 100 mL/minute, the Trifusion catheter and the TidalPort device operated at lower pressures than the Vortex ports. Within typical clinical flow rates, neither catheter material nor internal diameter substantially affected pressure. CONCLUSION: Central venous access devices show large differences in pressure within flow rates used routinely in clinical settings. These differences cannot be fully attributed to catheter material composition or catheter internal diameter. PMID- 29443413 TI - Vascular access for therapeutic plasma exchange. AB - Therapeutic plasma exchange is an apheresis modality in which plasma is separated from the blood cellular components ex vivo, discarded, and replaced with an isosmotic fluid (most commonly 5% albumin) to maintain appropriate oncotic pressure in the patient. Therapeutic plasma exchange is used in the treatment of many diseases and indications. The recent seventh edition of the American Society for Apheresis guidelines indicates approximately 72 diseases and 116 indications for which therapeutic plasma exchange may be effective. One of the critical aspects for the successful performance of therapeutic plasma exchange is appropriate vascular access to provide high blood flow for the collection and return phases of the procedure, especially because most patients who need therapeutic plasma exchange will require more than one treatment over days to weeks. This article provides an overview of the characteristics of therapeutic plasma exchange, the clinical diseases and indications that may be treated with therapeutic plasma exchange, and the different types of vascular access employed, with their advantages and disadvantages. The latter may include peripheral venous access and intravascular or implantable access devices, such as arteriovenous grafts and fistulas, central venous catheters, and central venous catheters tunneled with ports.

AB - BACKGROUND AND AIMS: Opioid maintenance treatment (OMT) is recommended to opioid dependent females during pregnancy. However, it is not clear which medication should be preferred. We aimed to compare neonatal outcomes after prenatal exposure to methadone (M) and buprenorphine (B) in two European countries. DESIGN: Nation-wide register-based cohort study using personalized IDs assigned to all citizens for data linkage. SETTING: The Czech Republic (2000-14) and Norway (2004-13). [Correction added after online publication on 26 April 2018: The Czech Republic (2000-04) corrected to (2000-14).] PARTICIPANTS: Opioid dependent pregnant Czech (n = 333) and Norwegian (n = 235) women in OMT who received either B or M during pregnancy and their newborns. MEASUREMENTS: We linked data from health registries to identify the neonatal outcomes: gestational age, preterm birth, birth weight, length and head circumference, small for gestational age, miscarriages and stillbirth, neonatal abstinence syndrome (NAS) and Apgar score. We performed multivariate linear regression and binary logistic regression to explore the associations between M and B exposure and outcomes. Regression coefficient (beta) and odds ratio (OR) were computed. FINDINGS: Most neonatal outcomes were more favourable after exposure to B compared with M, but none of the differences was statistically significant. For instance, in the multivariate analysis, birth weight was beta = 111.6 g [95% confidence interval (CI) = -10.5 to 233.6 and beta = 83.1 g, 95% CI = -100.8 to 267.0] higher after B exposure in the Czech Republic and Norway, respectively. Adjusted OR of NAS for B compared with M was 0.94 (95% CI = 0.46-1.92) in the Norwegian cohort. CONCLUSIONS: Two national cohorts of women receiving opioid maintenance treatment during pregnancy showed small but not statistically significant differences in neonatal outcomes in favour of buprenorphine compared with methadone.

AB - BACKGROUND: The anterolateral thigh (ALT) free flap has been an extremely versatile flap. The purpose of this study was to propose comprehensive functional assessments of the donor site. METHODS: A total of 33 ALT flaps were enrolled prospectively. Objective assessments included isokinetic testing of the knee, and electromyographic examination of the lateral femoral cutaneous nerve (LFCN). The Patient and Observer Scar Assessment Scale (POSAS) was used to subjectively assess the donor-site scar. RESULTS: On the donor side, a significant decrease in most isokinetic muscle strength values was obvious 1 year postoperatively (P < .01). The normal side showed a compensatory increase 1 year postoperatively in the majority of isokinetic muscle strength values (P < .05). The majority of patients (70%) showed decreased sensory conduction velocity of the LFCN or no response to the microcurrent stimulation postoperatively. The aesthetic outcome was satisfactory. CONCLUSION: The decline in functional parameters at the donor site was common. However, much more research is needed. PMID- 29443416 TI - Diabetic neuropathy differs between type 1 and type 2 diabetes: Insights from magnetic resonance neurography. AB - OBJECTIVE: To visualize and quantify differences of microstructural nerve damage in distal symmetric diabetic neuropathy (DPN) between type 1 diabetes (T1D) and type 2 diabetes (T2D), and to detect correlations between neuropathic symptoms and serological risk factors. METHODS: Three-tesla magnetic resonance neurography of the sciatic nerve was performed in 120 patients (T1D, n = 35; T2D, n = 85) with either DPN (n = 84) or no DPN (n = 36). Results were subsequently correlated with clinical, serological, and electrophysiological patient data. RESULTS: T2 weighted (T2w)-hyperintense lesions correlated negatively with tibial compound motor action potential (r = -0.58, p < 0.0001) and peroneal nerve conduction (r = 0.51, p = 0.0002), and positively with neuropathy disability score (NDS; r = 0.54, p < 0.0001), neuropathy symptom score (NSS; r = 0.52, p < 0.0001), and HbA1c level (r = 0.23, p = 0.014). T2w-hypointense lesions correlated positively with NDS (r = 0.28, p = 0.002), NSS (r = 0.36, p < 0.0001), and serum triglycerides (r = 0.34, p = 0.0003), and negatively with serum high-density lipoprotein (HDL; r = -0.48, p < 0.0001). For DPN in T1D, elevated values of T2w hyperintense lesions (19.67 +/- 4.13% vs 12.49 +/- 1.23%, p = 0.027) and HbA1c (8.74 +/- 0.29% vs 7.11 +/- 0.16%, p < 0.0001) were found when compared to T2D. For DPN in T2D, elevated T2w-hypointense lesions (23.41 +/- 2.69mm3 vs 11.43 +/- 1.74mm3 , p = 0.046) and triglycerides (220.70 +/- 23.70mg/dl vs 106.60 +/- 14.51mg/dl, p < 0.0001), and lower serum HDL (51.29 +/- 3.02mg/dl vs 70.79 +/- 4.65mg/dl, p < 0.0001) were found when compared to T1D. INTERPRETATION: The predominant type of nerve lesion in DPN differs between T1D and T2D. Correlations found between lesion type and serological parameters indicate that predominant nerve lesions in T1D are associated with poor glycemic control and loss of nerve conduction, whereas predominant lesions in T2D are associated with changes in lipid metabolism. These findings may be helpful for future studies on the underlying pathophysiological pathways and possible treatments for DPN in T1D and T2D. Ann Neurol 2018;83:588-598.

AB - Recent studies indicate that chemoattractant cytokines (chemokines) and their receptors modulate intestinal B lymphocytes in different ways, including regulating their maturity and differentiation in the bone marrow and homing to intestinal target tissues. Here, we review several important chemokine/chemokine receptor axes that guide intestinal B cells, focusing on the homing and migration of IgA antibody-secreting cells (IgA-ASCs) to intestinal-associated lymphoid tissues. We describe the selective regulation of these chemokine axes in coordinating the IgA-ASC trafficking in intestinal diseases. Finally, we discuss the role of B cells as chemokine producers serving dual roles in regulating the mucosal immune microenvironment. PMID- 29443418 TI - Potential roles of YCF54 and ferredoxin-NADPH reductase for magnesium protoporphyrin monomethylester cyclase. AB - Chlorophyll is synthesized from activated glutamate in the tetrapyrrole biosynthesis pathway through at least 20 different enzymatic reactions. Among these, the MgProto monomethylester (MgProtoME) cyclase catalyzes the formation of a fifth isocyclic ring to tetrapyrroles to form protochlorophyllide. The enzyme consists of two proteins. The CHL27 protein is proposed to be the catalytic component, while LCAA/YCF54 likely acts as a scaffolding factor. In comparison to other reactions of chlorophyll biosynthesis, this enzymatic step lacks clear elucidation and it is hardly understood, how electrons are delivered for the NADPH-dependent cyclization reaction. The present study intends to elucidate more precisely the role of LCAA/YCF54. Transgenic Arabidopsis lines with inactivated and overexpressed YCF54 reveal the mutual stability of YCF54 and CHL27. Among the YCF54-interacting proteins, the plastidal ferredoxin-NADPH reductase (FNR) was identified. We showed in N. tabacum and A. thaliana that a deficit of FNR1 or YCF54 caused MgProtoME accumulation, the substrate of the cyclase, and destabilization of the cyclase subunits. It is proposed that FNR serves as a potential donor for electrons required in the cyclase reaction and connects chlorophyll synthesis with photosynthetic activity. PMID- 29443419 TI - Sex chromosomes and speciation in birds and other ZW systems. AB - Theory and empirical patterns suggest a disproportionate role for sex chromosomes in evolution and speciation. Focusing on ZW sex determination (females ZW, males ZZ; the system in birds, many snakes, and lepidopterans), I review how evolutionary dynamics are expected to differ between the Z, W and the autosomes, discuss how these differences may lead to a greater role of the sex chromosomes in speciation and use data from birds to compare relative evolutionary rates of sex chromosomes and autosomes. Neutral mutations, partially or completely recessive beneficial mutations, and deleterious mutations under many conditions are expected to accumulate faster on the Z than on autosomes. Sexually antagonistic polymorphisms are expected to arise on the Z, raising the possibility of the spread of preference alleles. The faster accumulation of many types of mutations and the potential for complex evolutionary dynamics of sexually antagonistic traits and preferences contribute to a role for the Z chromosome in speciation. A quantitative comparison among a wide variety of bird species shows that the Z tends to have less within-population diversity and greater between-species differentiation than the autosomes, likely due to both adaptive evolution and a greater rate of fixation of deleterious alleles. The W chromosome also shows strong potential to be involved in speciation, in part because of its co-inheritance with the mitochondrial genome. While theory and empirical evidence suggest a disproportionate role for sex chromosomes in speciation, the importance of sex chromosomes is moderated by their small size compared to the whole genome. PMID- 29443420 TI - Experimentally altered rainfall regimes and host root traits affect grassland arbuscular mycorrhizal fungal communities. AB - Future climate scenarios predict changes in rainfall regimes. These changes are expected to affect plants via effects on the expression of root traits associated with water and nutrient uptake. Associated microorganisms may also respond to these new precipitation regimes, either directly in response to changes in the soil environment or indirectly in response to altered root trait expression. We characterized arbuscular mycorrhizal (AM) fungal communities in an Australian grassland exposed to experimentally altered rainfall regimes. We used Illumina sequencing to assess the responses of AM fungal communities associated with four plant species sampled in different watering treatments and evaluated the extent to which shifts were associated with changes in root traits. We observed that altered rainfall regimes affected the composition but not the richness of the AM fungal communities, and we found distinctive communities in the increased rainfall treatment. We found no evidence of altered rainfall regime effects via changes in host physiology because none of the studied traits were affected by changes in rainfall. However, specific root length was observed to correlate with AM fungal richness, while concentrations of phosphorus and calcium in root tissue and the proportion of root length allocated to fine roots were correlated to community composition. Our study provides evidence that climate change and its effects on rainfall may influence AM fungal community assembly, as do plant traits related to plant nutrition and water uptake. We did not find evidence that host responses to altered rainfall drive AM fungal community assembly in this grassland ecosystem. PMID- 29443421 TI - Diabetes UK evidence-based nutrition guidelines for the prevention and management of diabetes. AB - A summary of the latest evidence-based nutrition guidelines for the prevention and management of diabetes is presented. These guidelines are based on existing recommendations last published in 2011, and were formulated by an expert panel of specialist dietitians after a literature review of recent evidence. Recommendations have been made in terms of foods rather than nutrients wherever possible. Guidelines for education and care delivery, prevention of Type 2 diabetes, glycaemic control for Type 1 and Type 2 diabetes, cardiovascular disease risk management, management of diabetes-related complications, other considerations including comorbidities, nutrition support, pregnancy and lactation, eating disorders, micronutrients, food supplements, functional foods, commercial diabetic foods and nutritive and non-nutritive sweeteners are included. The sections on pregnancy and prevention of Type 2 diabetes have been enlarged and the weight management section modified to include considerations of remission of Type 2 diabetes. A section evaluating detailed considerations in ethnic minorities has been included as a new topic. The guidelines were graded using adapted 'GRADE' methodology and, where strong evidence was lacking, grading was not allocated. These 2018 guidelines emphasize a flexible, individualized approach to diabetes management and weight loss and highlight the emerging evidence for remission of Type 2 diabetes. The full guideline document is available at www.diabetes.org.uk/nutrition-guidelines. PMID- 29443422 TI - Linking dendroecology and association genetics in natural populations: Stress responses archived in tree rings associate with SNP genotypes in silver fir (Abies alba Mill.). AB - Genetic association studies in forest trees would greatly benefit from information on the response of trees to environmental stressors over time, which can be provided by dendroecological analysis. Here, we jointly analysed dendroecological and genetic data of surviving silver fir trees to explore the genetic basis of their response to the iconic stress episode of the 1970s and 1980s that led to large-scale forest dieback in Central Europe and has been attributed to air pollution. Specifically, we derived dendrophenotypic measures from 190 trees in the Bavarian Forest that characterize the resistance, resilience and recovery during this growth depression, and in the drought year in 1976. By focusing on relative growth changes of trees and by standardizing the dendrophenotypes within stands, we accounted for variation introduced by micro- and macroscale environmental differences. We associated the dendrophenotypes with single nucleotide polymorphisms (SNPs) in candidate genes using general linear models (GLMs) and the machine learning algorithm random forest with subsequent feature selection. Most trees at our study sites experienced a severe growth decline from 1974 until the mid-1980s with minimum values during the drought year. Fifteen genes were associated with the dendrophenotypes, including genes linked to photosynthesis and drought stress. With our study, we show that dendrophenotypes can be a powerful resource for genetic association studies that permit to account for micro- and macroenvironmental variation when data are derived from natural populations. We call for a wider collaboration of dendroecologists and forest geneticists to integrate individual tree-level dendrophenotypes in genetic association studies.

AB - In the presence of catalytic [RuCl2 (p-cym)]2 and using Li3 PO4 as the base, benzoic acids react with olefins in water to afford the corresponding 2 alkylbenzoic acids in moderate to excellent yields. This C-H alkylation process is generally applicable to diversely substituted electron-rich and electron deficient benzoic acids, along with alpha,beta-unsaturated olefins including unprotected acrylic acid. The widely available carboxylate directing group can be removed or utilized for further derivatization. Mechanistic investigations revealed that the transformation proceeds via a ruthenacycle intermediate. PMID- 29443424 TI - CCL23 is a promising biomarker of injury in patients with ischaemic stroke. PMID- 29443425 TI - Long-Term Atherosclerotic Vascular Disease Risk and Prognosis in Elderly Women With Abdominal Aortic Calcification on Lateral Spine Images Captured During Bone Density Testing: A Prospective Study. AB - Lateral spine images are captured using bone densitometers for vertebral fracture assessment (VFA) in older women. Abdominal aortic calcification (AAC) is commonly seen on these images; however, the long-term prognosis in women with AAC remains uncertain. In a prospective study of 1052 community-dwelling ambulant white women over 70 years old abdominal aortic calcification 24 scale (AAC24) scores were calculated from digital lateral spine images captured during bone density testing in 1998 or 1999. Cardiovascular risk factors were assessed in 1998, whereas 14.5 year atherosclerotic vascular disease (ASVD)-related hospitalizations and deaths (events) were available through linked health records. Using established cut points for AAC 471 women (45%) had low AAC (AAC24 score 0 or 1), 387 (37%) moderate AAC (AAC24 score 2-5), and 197 (19%) had high AAC (AAC24 score >=6). Over 14.5 years, 420 women experienced an ASVD event. Increasing severity of AAC was associated with increased absolute risk of ASVD events (37%, 39%, and 49%, respectively, p = 0.008 for trend), ASVD deaths (15%, 21%, and 27%, respectively, p < 0.001 for trend), and all-cause mortality (30%, 38%, and 44%, respectively, p < 0.001 for trend). After adjusting for Framingham risk scores, women with high AAC had increased relative hazard for ASVD events, HR 1.37 (95% CI, 1.07 to 1.77; p = 0.013) compared to women with low AAC. Similarly, women with moderate AAC and high AAC had increased relative hazards for ASVD deaths HR 1.41 (95% CI, 1.03 to 1.94; p = 0.034) and HR 1.80 (95% CI, 1.26 to 2.57; p = 0.001), or any deaths HR 1.30 (95% CI, 1.03 to 1.64; p = 0.026) and HR 1.53 (95% CI, 1.17 to 2.00; p = 0.002), compared to women with low AAC. In conclusion, more advanced AAC on images captured for VFA is associated with long-term ASVD hospitalizations and deaths before and after adjusting for Framingham risk scores. AAC assessment could be considered in addition to VFA to identify individuals who may benefit for more aggressive cardiovascular primary prevention strategies.

AB - Naringin is a flavanone that widely presents on daily diet and traditional medicinal materials. The ratios of naringin C-2 diastereomers are found different in reported samples, thus suspiciously leading to various functions. In this study, we measured the interconversion of C-2 diastereomers intensively with ultimate high-performance liquid chromatography and circular dichroism spectra. We examined the diastereomeric naringins in fresh citrus fruit, Huajuhong decoction pieces, and naringin tablet; evaluated the impact of tablet production procedures in factory; and monitored the rapid racemization in incubation. The results not only confirmed that enzyme, temperature, and pH condition could influence the interconversion but also demonstrated that diverse ratios of diastereomers showed limited influence on metabolic behaviors of naringin in the blood, which consequently cause comparable bioactivities. This study could provide comprehensive understanding of diastereomeric interconversion and provide useful reference for drug development.

AB - Hydrodefluorination reactions (HDF) of per- and polyfluorinated olefins and arenes by cheap aluminum alkyl hydrides in non-coordinating solvents can be catalyzed by O and N donors. TONs with respect to the organocatalysts of up to 87 have been observed. Depending on substrate and concentration, high selectivities can be achieved. For the prototypical hexafluoropropene, however, low selectivities are observed (E/Z~2). DFT studies show that the preferred HDF mechanism for this substrate in the presence of donor solvents proceeds from the dimer Me4 Al2 (MU-H)2 ?THF by nucleophilic vinylic substitution (SN V)-like transition states with low selectivity and without formation of an intermediate, not via hydrometallation or sigma-bond metathesis. In the absence of donor solvents, hydrometallation is preferred but this is associated with inaccessibly high activation barriers at low temperatures. Donor solvents activate the aluminum hydride bond, lower the barrier for HDF significantly, and switch the product preference from Z to E. The exact nature of the donor has only a minimal influence on the selectivity at low concentrations, as the donor is located far away from the active center in the transition states. The mechanism changes at higher donor concentrations and proceeds from Me2 AlH?THF via SN V and formation of a stable intermediate, from which elimination is unselective, which results in a loss of selectivity. PMID- 29443429 TI - Electronic circular dichroism for the detection of microalbuminuria. AB - Over the past decades, chiroptical spectroscopy has proved its incomparable ability to elucidate the structure and spatial arrangement of chiral molecules. Systematic analysis of biomolecules in the natural environment of biofluids, however, remains challenging. In this study, we used chiroptical spectroscopy to monitor urinary levels of human serum albumin. Not only severe proteinuria but even just a slightly increased urinary excretion of albumin (microalbuminuria) may indicate serious health complications, especially for diabetic individuals. Given the chiral nature of albumin and its typical spectral pattern, it may be easily observable by chiroptical spectroscopy, particularly electronic circular dichroism. The performed chiroptical analysis of urine not only allowed the detection of clinically confirmed microalbuminuria but was also able to reveal this pathological condition in cases beyond the diagnostic capability of common clinical procedures. Thus, our approach suggests that electronic circular dichroism is a useful tool for the fast and reliable qualitative monitoring of microalbuminuria with the potential for a quantitative analysis in the future.

Recent progress in the design, fabrication, and operation of these miniaturized devices has greatly enhanced their versatility. In this report, the most recent progress on the manipulation of small-scale robots based on power sources, such as magnetic fields, light, acoustic waves, electric fields, thermal energy, or combinations of these, is surveyed.

PMID- 29443431 TI - Sarcomas of the sinonasal tract. AB - BACKGROUND: Sinonasal sarcomas are rare and heterogeneous in nature. Continuously collecting data influencing the prognosis is fundamental for optimizing therapeutic assessment of this highly destructive neoplasm. METHODS: We conducted a single-institution retrospective cohort study considering 27 patients with sinonasal sarcoma. RESULTS: The overall survival (OS) rates for 1 year and 5 years were calculated as 74% and 36%, respectively. Extent of the primary tumor (P = .010), nodal spread (P = .009), and age (P = .004) significantly reduced the OS. Disease-free survival (DFS) was significantly reduced by age (P = .003), extent of the primary (P = .006), nodal (P = .004), and hematogenous (P = .048) spread. Multimodal therapy including surgery improved the OS and DFS rates (P < .05). CONCLUSION: Prognosis is poor due to late disease recognition. However, multimodal therapeutic regimens, including surgery, may improve the outcome. PMID- 29443432 TI - Bioorthogonal Metabolic DNA Labelling using Vinyl Thioether-Modified Thymidine and o-Quinolinone Quinone Methide. AB - Bioorthogonal metabolic DNA labeling with fluorochromes is a powerful strategy to visualize DNA molecules and their functions. Here, we report the development of a new DNA metabolic labeling strategy enabled by the catalyst-free bioorthogonal ligation using vinyl thioether modified thymidine and o-quinolinone quinone methide. With the newly designed vinyl thioether-modified thymidine (VTdT), we added labeling tags on cellular DNA, which could further be linked to fluorochromes in cells. Therefore, we successfully visualized the DNA localization within cells as well as single DNA molecules without other staining reagents. In addition, we further characterized this bioorthogonal DNA metabolic labeling using DNase I digestion, MS characterization of VTdT as well as VTdT oQQF conjugate in cell nuclei or mitochondria. This technique provides a powerful strategy to study DNA in cells, which paves the way to achieve future spatiotemporal deciphering of DNA synthesis and functions. PMID- 29443433 TI - Effects of anodal transcranial direct current stimulation over lower limb primary motor cortex on motor learning in healthy individuals. AB - Transcranial direct current stimulation (tDCS) is a neuromodulatory technique which alters motor functions in healthy humans and in neurological patients. Most studies so far investigated the effects of tDCS on mechanisms underlying improvements in upper limb performance. To investigate the effect of anodal tDCS over the lower limb motor cortex (M1) on lower limb motor learning in healthy volunteers, we conducted a randomized, single-blind and sham-controlled study. Thirty-three (25.81 +/- 3.85, 14 female) volunteers were included, and received anodal or sham tDCS over the left M1 (M1-tDCS); 0.0625 mA/cm2 anodal tDCS was applied for 15 min during performance of a visuo-motor task (VMT) with the right leg. Motor learning was monitored for performance speed and accuracy based on electromyographic recordings. We also investigated the influence of electrode size and baseline responsivity to transcranial magnetic stimulation (TMS) on the stimulation effects. Relative to baseline measures, only M1-tDCS applied with small electrodes and in volunteers with high baseline sensitivity to TMS significantly improved VMT performance. The computational analysis showed that the small anode was more specific to the targeted leg motor cortex volume when compared to the large anode. We conclude that anodal M1-tDCS modulates VMT performance in healthy subjects. As these effects critically depend on sensitivity to TMS and electrode size, future studies should investigate the effects of intensified tDCS and/or model-based different electrode positions in low-sensitivity TMS individuals. PMID- 29443434 TI - Expanding the Abortion Provider Workforce: A Qualitative Study of Organizations Implementing a New California Policy. AB - CONTEXT: Access to abortion care in the United States varies according to multiple factors, including location, state regulation and provider availability. In 2013, California enacted a law that authorized nurse practitioners (NPs), certified nurse-midwives (CNMs) and physician assistants (PAs) to provide first trimester aspiration abortions; little is known about organizations' experiences in implementing this policy change. METHODS: Beginning 10 and 24 months after implementation of the new law, semistructured interviews were conducted with 20 administrators whose five organizations trained and employed NPs, CNMs and PAs as providers of aspiration abortions. Interview data on the organizations' experiences were analyzed thematically, and facilitators of and barriers to implementation were identified. RESULTS: Administrators were committed to the provision of aspiration abortions by NPs, CNMs and PAs, and nearly all identified improved access to care and complication management as clear benefits of the policy change. However, integration of the new providers was uneven and depended on a variety of circumstances. Organizational disincentives included financial and logistical costs incurred in trying to deploy and integrate the different types of providers. Some administrators found that increased costs were outweighed by improved patient care, whereas others did not. In general, having a strong administrative champion within the organization made a critical difference. CONCLUSIONS: California's expansion of the abortion-providing workforce had a positive impact on patient care in the sampled organizations. However, various organizational obstacles must be addressed to more fully realize the benefits of having NPs, CNMs and PAs provide aspiration abortions. PMID- 29443435 TI - A Thermally Insulating Textile Inspired by Polar Bear Hair. AB - Animals living in the extremely cold environment, such as polar bears, have shown amazing capability to keep warm, benefiting from their hollow hairs. Mimicking such a strategy in synthetic fibers would stimulate smart textiles for efficient personal thermal management, which plays an important role in preventing heat loss and improving efficiency in house warming energy consumption. Here, a "freeze-spinning" technique is used to realize continuous and large-scale fabrication of fibers with aligned porous structure, mimicking polar bear hairs, which is difficult to achieve by other methods. A textile woven with such biomimetic fibers shows an excellent thermal insulation property as well as good breathability and wearability. In addition to passively insulating heat loss, the textile can also function as a wearable heater, when doped with electroheating materials such as carbon nanotubes, to induce fast thermal response and uniform electroheating while maintaining its soft and porous nature for comfortable wearing. PMID- 29443436 TI - Fitness costs of infection with Serratia symbiotica are associated with greater susceptibility to insecticides in the pea aphid Acyrthosiphon pisum. AB - BACKGROUND: Aphids are agricultural pests that damage crops by direct feeding and by vectoring important plant viruses. Bacterial symbionts can influence aphid biology, e.g. by providing essential nutrients or facilitating adaptations to biotic and abiotic stress. RESULTS: We investigated the pea aphid (Acyrthosiphon pisum Harris) and its commonly associated secondary bacterial symbiont Serratia symbiotica to study the effect of this symbiont on host fitness and susceptibility to the insecticides imidacloprid, chlorpyrifos methyl, methomyl, cyantraniliprole and spirotetramat. There is emerging evidence that members of the genus Serratia can degrade and/or detoxify diverse insecticides. Therefore, we hypothesized that S. symbiotica may promote resistance to these artificial stress agents in aphids. Our results showed that Serratia-infected aphids were more susceptible to most of the tested insecticides than non-infected aphids. This probably reflects the severe fitness costs associated with S. symbiotica, which negatively affects development, reproduction and body weight. CONCLUSION: Our study demonstrates that S. symbiotica plays an important role in the ability of aphid hosts to tolerate insecticides. These results provide insight into the potential changes in tolerance to insecticides in the field because there is a continuous and dynamic process of symbiont acquisition and loss that may directly affect host biology.

AB - BACKGROUND: Determining possible associated factors and the influencing pathways to hemoglobin A1C (HbA1C) levels and quality of life (QoL) will facilitate the development of effective interventions to improve the physical and psychosocial health of patients with type 2 diabetes mellitus (T2DM). OBJECTIVES: To test a hypothesized model that addressed the pathways among personal characteristics, social support, diabetes distress, and self-care behaviors to HbA1C and QoL. METHODS: A total of 382 adults with T2DM were recruited. Self-reported questionnaires and medical records were used to collect data regarding personal characteristics, diabetes distress, and social support at baseline. The self-care behaviors characters were collected 6 months later, as well as QoL and HbA1C levels 1 year later. RESULTS: The 12-month QoL directly affected 12-month HbA1C levels. The 6-month self-care behaviors directly affected 12-month QoL, and indirectly affected 12-month HbA1C levels through 12-month QoL. Baseline diabetes distress directly affected 12-month QoL. Moreover, baseline diabetes distress indirectly affected 12-month HbA1C levels through 12-month QoL. Baseline social support directly affected baseline diabetes distress and 6-month self-care behaviors. In addition, baseline social support indirectly affected 12-month QoL through baseline diabetes distress. Baseline social support also indirectly affected 12-month QoL through 6-month self-care behaviors. LINKING EVIDENCE TO ACTION: Enhancing QoL is important to improve HbA1C levels. Enhancing self-care behaviors is essential to improve subsequent HbA1C control and QoL. Reducing diabetes distress is crucial to improve subsequent QoL. Improving social support is suggested a favorable strategy to reduce diabetes distress and enhance subsequent self-care behaviors in patients with T2DM. PMID- 29443438 TI - Obesity is associated with incident atrial fibrillation independent of gender: A meta-analysis. AB - BACKGROUND: The prevalence of obesity is increasing among the general population. Obesity is associated with increased risk of several cardiovascular conditions, which in turn may increase the risk for atrial fibrillation (AF). We performed a meta-analysis of cohort studies that examined the effect of obesity on the incidence of AF. In addition, we examined the effect of obesity on the incidence of AF stratified by gender. METHODS AND RESULTS: We searched the MEDLINE and EMBASE databases for studies evaluating the effect of obesity on AF. Pooled risk ratios (RR) with 95% confidence intervals (CI) were calculated using a random effects model. Sixteen trials involving 587,372 subjects were included in the analysis. Obesity was defined as body mass index >30 kg/m2 . AF during follow-up developed in 5,751 of 91,031 (6.3%) obese subjects and in 15,346 of 496,341 (3.1%) nonobese subjects (RR = 1.51, 95% CI 1.35 to 1.68; P < 0.00001). Based on the pooled estimate across the studies, the effect of obesity on incident AF was similar in men (RR = 1.41, 95% 1.24 to 1.62; P < 0.00001) and women (RR = 1.53, 95% CI 1.19 to 1.97; P < 0.00001). CONCLUSION: Obesity is associated with an increased risk of new-onset AF in susceptible individuals. This effect appears to be consistent in both genders. Further studies are warranted to examine the impact of weight loss interventions on the risk of developing AF.

AB - BACKGROUND: Understanding the complex interrelationships between combat injuries, physical health, and mental health symptoms is critical to addressing the healthcare needs of wounded military personnel and veterans. The relationship between injury characteristics, pain, posttraumatic stress disorder (PTSD), and depression among combat-injured military personnel is unique to modern conflicts and understudied in the nursing literature. AIM: This integrative review synthesizes clinical presentations and relationships of combat injury, PTSD, depression, and pain in Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) United States military service members and veterans. METHODS: A literature search was conducted using relative key terms across databases to identify peer-reviewed publications between 2001 and 2016 that examined health outcomes of combat-injured persons in OEF and OIF. The quality of evidence was evaluated and results synthesized to examine the association of combat injury as a risk factor for PTSD, the relationship of PTSD and depression pre- and postinjury, and pain management throughout care. RESULTS: Twenty-two articles were included in this review. Greater injury and pain severity poses risks for developing PTSD following combat injury, while early symptom management lessens risks for PTSD. Depression appears to be both a contributing risk factor to postinjury PTSD, as well as a comorbidity. LINKING EVIDENCE TO ACTION: Findings demonstrate a compelling need for improvements in standardized assessment of pain and mental health symptoms across transitions in care. This integrative review informs nurse researchers and providers of the clinical characteristics of pain, PTSD, and depression following combat injury and offers implications for future research promoting optimal surveillance of symptoms.

PMID- 29443441 TI - Cumulative live birth rates and perinatal outcomes with the use of time-lapse imaging incubators for embryo culture: a retrospective cohort study of 1882 ART cycles. AB - OBJECTIVE: Comparison of live birth rates and the perinatal outcomes after fresh and frozen embryo transfer between time-lapse imaging (TLI) and standard culture (SC) incubators. DESIGN: Retrospective cohort study. SETTING: A single tertiary level IVF unit. POPULATION: Women undergoing IVF between January 2014 and October 2015. METHODS: Comparison was done between 1064 IVF cycles using TLI (TLI cycles) and 818 IVF cycles using SC (SC cycles). MAIN OUTCOME MEASURES: Cumulative live birth rate per oocyte retrieval and perinatal outcomes including birthweight, gestational age, preterm birth (PTB) (<37 weeks), early preterm birth (PTB; <32 weeks), low birthweight (LBW; <2500 g), very LBW (<1500 g) and macrosomia (>4500 g). RESULTS: The fresh embryo transfer live birth rate was noted to be higher for TLI cycles [TLI 36.8 versus SC 33.9%, adjusted odds ratio (aOR) 1.28, 95% CI 1.05 1.57], but the frozen embryo transfer live birth rates were not significantly different. The mean birthweight was higher in the TLI group after both fresh [adjusted mean difference (aMD) 174.78 g, 95% CI 64.80-284.77] and frozen embryo transfers (aMD 175.91 g, 95% CI 16.98-334.84). After a fresh embryo transfer, there was a lower risk of early PTB and very LBW in the TLI group. Among frozen embryo transfers, there was a lower risk of early PTB and LBW in the TLI group. CONCLUSIONS: TLI incubators are associated with improved perinatal outcomes and higher mean birthweight after fresh and frozen embryo transfer. TWEETABLE ABSTRACT: Time-lapse imaging incubators in IVF improve perinatal outcomes after both fresh and frozen embryo transfers. PMID- 29443442 TI - Paediatric acute disseminated encephalomyelitis followed by optic neuritis: disease course, treatment response and outcome. AB - BACKGROUND AND PURPOSE: Acute disseminated encephalomyelitis followed by optic neuritis (ADEM-ON) is a rare demyelinating syndrome that is different from multiple sclerosis and neuromyelitis optica spectrum disorder. The aim of this study was to describe the disease course, treatment response and outcome of children with ADEM-ON. METHODS: Children of <18 years of age were identified from six countries of the EU Paediatric Demyelinating Disease Consortium. Patients fulfilled the diagnostic criteria for ADEM followed by at least one ON. Anti myelin oligodendrocyte glycoprotein (MOG) antibodies were tested in all patients. RESULTS: In this study of 17 patients (nine boys) with ADEM-ON, anti-myelin oligodendrocyte glycoprotein (MOG) antibodies were identified in 16 patients. Age at onset was 6.1 years (interquartile range, 5.1-9.2 years). Twelve patients received oral prednisolone and 10 received maintenance immunosuppression (e.g. azathioprine, intravenous immunoglobulins, Rituximab). During a follow-up of 5.3 years (interquartile range, 1.8-10.2 years), 54 relapses occurred with a median of 3 relapses per patient (range, 1-9 per patient). Patients relapsed on all treatments but no relapses occurred on a prednisolone dose >10 mg/day. Visual and cognitive residual deficits were common in this group. CONCLUSIONS: Acute disseminated encephalomyelitis followed by optic neuritis is an anti-MOG antibody associated relapsing disorder that can have a heterogeneous disease course. Patients were refractory for maintenance immunosuppression and appeared to be corticosteroid-dependent. Further international collaborations are now required to unify guidelines in this difficult-to-manage group of patients. PMID- 29443443 TI - Intermittent response to para-Hisian pacing: A more than paradoxical response. PMID- 29443444 TI - Diabetes and intracerebral hemorrhage: baseline characteristics and mortality. AB - BACKGROUND AND PURPOSE: Acknowledging the conflicting evidence for diabetes as a predictor of short- and long-term mortality following an intracerebral hemorrhage (ICH), we compared baseline characteristics and 30-day and long-term mortality between patients with and without diabetes after an ICH, paying special attention to differences between type 1 (T1D) and type 2 (T2D) diabetes. METHODS: Patients with a first-ever ICH were followed for a median of 2.3 years. Adjusting for demographics, comorbidities and documented ICH characteristics increasing mortality after ICH, logistic regression analysis assessed factors associated with case fatality and 1-year survival among the 30-day survivors. Diabetes was compared with patients without diabetes in separate models as (i) any diabetes and (ii) T1D or T2D. RESULTS: Of our 969 patients, 813 (83.9%) had no diabetes, 41 (4.2%) had T1D and 115 (11.9%) had T2D. Compared with patients without diabetes, those with diabetes were younger, more often men and more frequently had hypertension, coronary heart disease and chronic kidney disease, with similar ICH characteristics. Patients with T1D were younger, more often had chronic kidney disease and brainstem ICH, and less often had atrial fibrillation and lobar ICH, than did patients with T2D. Diabetes had no impact on case fatality. Any diabetes (odds ratio, 2.57; 1.19-5.52), T1D (odds ratio, 7.04; 1.14-43.48) and T2D (odds ratio, 2.32; 1.04-5.17) were independently associated with 1-year mortality. CONCLUSIONS: Patients with ICH with diabetes exhibited a distinct pattern of comorbidities and disease characteristics with specific differences between T1D and T2D. Despite their younger age, T1D seems to carry a substantially higher likelihood of long-term mortality after an ICH than does T2D. PMID- 29443445 TI - Aspirin withdrawal in patients treated with ticagrelor presenting with non-ST elevation myocardial infarction. AB - : Essentials Strong P2Y12 blockade may cause platelet inhibition that is only minimally enhanced by aspirin. We evaluated aspirin withdrawal on platelet reactivity in ticagrelor treated patients. Aspirin withdrawal resulted in increased platelet reactivity to arachidonic acid. Aspirin withdrawal caused little difference in adenosine diphosphate-induced platelet aggregation. SUMMARY: Background Recent studies have shown that the thromboxane A2 -dependent pathway is dependent on the ADP-P2Y12 pathway, and that strong P2Y12 receptor blockade alone causes inhibition of platelet aggregation that is minimally enhanced by aspirin. Data from the PLATO trial suggested that, among ticagrelor-treated patients, high-dose versus low-dose (< 100 mg day-1 ) aspirin is associated with an increased risk fof ischemic events. Objectives To evaluate the impact of aspirin withdrawal on platelet reactivity in acute coronary syndrome (ACS) patients treated with a potent P2Y12 blocker. Patients/Methods This was a current prospective, randomized, placebo-controlled, double-blind, cross-over study. The study population comprised 22 consecutive ACS patients who underwent percutaneous coronary intervention and were treated with aspirin (100 mg day-1 ) and ticagrelor. Thirty days post-ACS, open-label aspirin was stopped, and patients were randomized to either blinded aspirin or placebo for 2 weeks, with each patient crossing over to the other arm for an additional 2 weeks. Platelet reactivity to arachidonic acid and ADP determined with light-transmission aggregometry (LTA) and VerifyNow was evaluated at baseline, and 2 weeks and 4 weeks later. Results Aspirin withdrawal resulted in an increase in arachidonic acid induced platelet reactivity as determined with both LTA (77.0% +/- 11.3% versus 20.8% +/- 4.4%) and VerifyNow (607.7 +/- 10.6 aspirin reaction units [ARU] versus 408.5 +/- 14.4 ARU). Platelet response to ADP, as determined with both LTA and VerifyNow, did not differ with either aspirin or placebo (32.9% +/- 2.6% versus 35.8% +/- 3.6%, and 33.5 +/- 6.4 P2Y12 reaction units (PRU) versus 29.6 +/ 5.7 PRU, respectively). Conclusions Aspirin withdrawal early post-ACS results in increased platelet reactivity in response to arachidonic acid, despite concomitant treatment with the potent P2Y12 blocker ticagrelor. PMID- 29443446 TI - Diverse Legionella-Like Bacteria Associated with Testate Amoebae of the Genus Arcella (Arcellinida: Amoebozoa). AB - Diverse species of Legionella and Legionella-like amoebal pathogens (LLAPs) have been identified as intracellular bacteria in many amoeboid protists. There are, however, other amoeboid groups such as testate amoeba for which we know little about their potential to host such bacteria. In this study, we assessed the occurrence and diversity of Legionella spp. in cultures and environmental isolates of freshwater arcellinid testate amoebae species, Arcella hemispherica, Arcella intermedia, and Arcella vulgaris, via 16S rRNA gene sequence analyses and fluorescent in situ hybridization (FISH). Analysis of the 16S rRNA gene sequences indicated that A. hemispherica, A. intermedia, and A. vulgaris host Legionella like bacteria with 94-98% identity to other Legionella spp. based on NCBI BLAST search. Phylogenetic analysis placed Legionella-like Arcella-associated bacteria (LLAB) in three different clusters within a tree containing all other members of Legionella and LLAPs. The intracellular localization of the Legionella within Arcella hosts was confirmed using FISH with a Legionella-specific probe. This study demonstrates that the host range of Legionella and Legionella-like bacteria in the Amoebozoa extends beyond members of "naked" amoebae species, with members of the testate amoebae potentially serving an ecological role in the dispersal, protection, and replication of Legionella spp. in natural environments. PMID- 29443447 TI - Cover crops mitigate direct greenhouse gases balance but reduce drainage under climate change scenarios in temperate climate with dry summers. AB - Cover crops provide ecosystem services such as storing atmospheric carbon in soils after incorporation of their residues. Cover crops also influence soil water balance, which can be an issue in temperate climates with dry summers as for example in southern France and Europe. As a consequence, it is necessary to understand cover crops' long-term influence on greenhouse gases (GHG) and water balances to assess their potential to mitigate climate change in arable cropping systems. We used the previously calibrated and validated soil-crop model STICS to simulate scenarios of cover crop introduction to assess their influence on rainfed and irrigated cropping systems and crop rotations distributed among five contrasted sites in southern France from 2007 to 2052. Our results showed that cover crops can improve mean direct GHG balance by 315 kg CO2 e ha-1 year-1 in the long term compared to that of bare soil. This was due mainly to an increase in carbon storage in the soil despite a slight increase in N2 O emissions which can be compensated by adapting fertilization. Cover crops also influence the water balance by reducing mean annual drainage by 20 mm/year but increasing mean annual evapotranspiration by 20 mm/year compared to those of bare soil. Using cover crops to improve the GHG balance may help to mitigate climate change by decreasing CO2 e emitted in cropping systems which can represent a decrease from 4.5% to 9% of annual GHG emissions of the French agriculture and forestry sector. However, if not well managed, they also could create water management issues in watersheds with shallow groundwater. Relationships between cover crop biomass and its influence on several variables such as drainage, carbon sequestration, and GHG emissions could be used to extend our results to other conditions to assess the cover crops' influence in a wider range of areas. PMID- 29443448 TI - An Intraneural Electrode for Bioelectronic Medicines for Treatment of Hypertension. AB - OBJECTIVES: As the left vagus nerve (LVN) mediates a baroreflex blood pressure (BP) decrease, LVN stimulation (LVNS) could be a therapy for hypertension. Moreover, LVNS could elegantly be adjusted to the patient's actual BP and physical activity by using the neural information about BP and respiration extractable from LVN. However, unselective LVNS will trigger undesirable side effects and therefore we here investigated the feasibility of using an intraneural electrode for extracting BP and respiration markers from the LVN and for selective LVNS. MATERIALS AND METHODS: Experiments were performed on six anesthetized pigs from which the BP was recorded using arterial catheters and the respiratory cycles by recording the airway pressure. An electrode comprising four tripolar channels was inserted longitudinally in the LVN of the animals to extract BP and respiration markers from the LVN and for selective LVNS. RESULTS: BP-related and respiratory-related neural profiles (BPnPs and RnPs, respectively) were derived from at least two electrode channels in all pigs. The BPnPs accurately resembled the BP waves and the RnPs accurately resembled the respiratory cycles, which suggests that those profiles could serve as BP and respiration markers, respectively. The BP was decreased by intraneural LVNS in all pigs and in four of those pigs such an effect was induced without major cardiac changes through a channel-selective stimulation. CONCLUSION: This study shows that it is feasible to extract BP and respiratory markers from the LVN with the tested intraneural electrode and suggests that this electrode could also be used for selective LVNS. PMID- 29443449 TI - Nitrogen-Doped Single Graphene Fiber with Platinum Water Dissociation Catalyst for Wearable Humidity Sensor. AB - Humidity sensors are essential components in wearable electronics for monitoring of environmental condition and physical state. In this work, a unique humidity sensing layer composed of nitrogen-doped reduced graphene oxide (nRGO) fiber on colorless polyimide film is proposed. Ultralong graphene oxide (GO) fibers are synthesized by solution assembly of large GO sheets assisted by lyotropic liquid crystal behavior. Chemical modification by nitrogen-doping is carried out under thermal annealing in H2 (4%)/N2 (96%) ambient to obtain highly conductive nRGO fiber. Very small (~2 nm) Pt nanoparticles are tightly anchored on the surface of the nRGO fiber as water dissociation catalysts by an optical sintering process. As a result, nRGO fiber can effectively detect wide humidity levels in the range of 6.1-66.4% relative humidity (RH). Furthermore, a 1.36-fold higher sensitivity (4.51%) at 66.4% RH is achieved using a Pt functionalized nRGO fiber (i.e., Pt nRGO fiber) compared with the sensitivity (3.53% at 66.4% RH) of pure nRGO fiber. Real-time and portable humidity sensing characteristics are successfully demonstrated toward exhaled breath using Pt-nRGO fiber integrated on a portable sensing module. The Pt-nRGO fiber with high sensitivity and wide range of humidity detection levels offers a new sensing platform for wearable humidity sensors.

AB - The JmjC histone lysyl demethylases (KDMs) play important roles in modulating histone methylation states and have the potential to be regulated by oxygen availability. Lys241 of the KDM4 subfamily is proposed to be important in oxygen binding by KDM4A. We report evidence that, although Lys241 is unlikely to be directly involved in oxygen binding, it has an important role in coupling 2 oxoglutarate cosubstrate oxidation with lysine demethylase activity. The results suggest that compounds promoting the uncoupling of substrate oxidation are of interest as JmjC-KDM inhibitors.

PMID- 29443452 TI - Development of Versatile Human In Vitro Vascularized Adipose Tissue Model with Serum-Free Angiogenesis and Natural Adipogenesis Induction. AB - Many adipose tissue-related diseases, such as obesity and type 2 diabetes, are worldwide epidemics. For studying these diseases, relevant human cell models are needed. In this study, we developed a vascularized adipose tissue model where human adipose stromal cells and human umbilical cord vein endothelial cells were cocultured with natural adipogenic and defined serum-free angiogenic media for 14 days. Several different protocols were compared to each other. The protocols varied in cell numbers and plating sequences. Lipid accumulation was studied with AdipoRed reagent, relative cell number with WST-1 reagent, gene expression of glut4, leptin, aP2, adiponectin, PPARgamma and PPARgamma2 with RT-qPCR. Secretion of adiponectin, leptin and aP2 was analysed with ELISA. The immunostained vascular network was imaged with Cell-IQ and area quantified using ImageJ. In this study, both angiogenesis and adipogenesis were successfully induced. Protocols produced strong lipid accumulation, good vascular network formation and induced adipocyte-specific protein secretion and expression of studied adipocyte genes. Results showed that cell numbers and cell plating sequences are important factors when aiming at in vitro standardized tissue model. Presence of mature vasculature appeared leads to faster the maturation of adipocytes judged by the lipid accumulation and gene expression results. The developed vascularized adipose tissue model is simple to use, easily modifiable to suit various applications and as such, a promising new tool for adipose tissue research when, for example, studying the effect of different cell types on adipose tissue function or for mechanistic studies.

AB - INTRODUCTION: To investigate voice quality (VQ) impairments in idiopathic Parkinson's disease (IPD) and to explore the impact of medical treatments and L Dopa challenge testing on voice. METHODS: Relevant studies published between January 1980 and June 2017 describing VQ evaluations in IPD were retrieved using PubMed, Scopus, Biological Abstracts, BioMed Central and Cochrane databases. Issues of clinical relevance, including IPD treatment efficiency and voice quality outcomes, were evaluated for each study. The grade of recommendation for each publication was determined according to the Oxford Centre for Evidence-Based Medicine evidence levels. RESULTS: The database research yielded 106 relevant publications, of which 33 studies met the inclusion criteria, for a total of 964 patients with IPD. Data were extracted by 3 independent physicians who identified 21, 11 and 1 trials with IIIb, IIb and IIa evidence levels, respectively. The main VQ assessment tools used were acoustic testing (N = 27), aerodynamic testing (N = 10), subjective measurements (N = 8) and videolaryngostroboscopy (N = 3). The majority of trials (N = 32/33) identified subjective or objective VQ improvements after medical treatment (N = 10) or better VQ evaluations in healthy subjects compared to patients with IPD (N = 22). Especially, our analysis supports that VQ overall improves during the L-Dopa challenge testing, making the VQ evaluation an additional tool for the IPD diagnosis. The methodology used to assess subjective and objective VQ substantially varied from 1 study to another. All of the included studies took into consideration the patient's clinical profile in the VQ analysis. CONCLUSION: The majority of studies supported that VQ assessments remain useful as outcome measures of the effectiveness of medical treatment and could be helpful for the IPD diagnosis based on L-Dopa challenge testing. Further controlled studies using standardised and transparent methodology for measuring acoustic parameters are necessary to confirm the place of each tool in both IPD diagnosis and treatment evaluation.

AB - Two isomeric N-annulated perylene diimide dimers, namely, p-BDNP and m-BDNP were designed and synthesized via geometric tuning. The distinct molecular geometry and packing arrangements of isomers with almost identical optical and electrochemical properties rendered us an in-depth understanding of the molecular structure-aggregation state-photovoltaic performance relationship. Blended with the commercially available donor PCE-10, p-BDNP and m-BDNP showed distinct differences in photovoltaic performance with power conversion efficiencies (PCEs) of 5.01 % and 4.15 %, respectively. PMID- 29443456 TI - Pharmacokinetics and Safety of Bazedoxifene in Hepatically Impaired and Healthy Postmenopausal Women. AB - Bazedoxifene, a selective estrogen receptor modulator with proestrogenic effects on bone and lipid metabolism and antiestrogenic effects on the breast and endometrium, is a treatment option for osteoporosis in postmenopausal women. It is extensively metabolized by the liver; therefore, a decrease in liver function was expected to decrease bazedoxifene clearance. This single-dose, open-label, inpatient/outpatient, nonrandomized study assessed the pharmacokinetics of bazedoxifene 20 mg in 18 postmenopausal women with hepatic impairment and 18 matched healthy postmenopausal women. Bazedoxifene elimination was slower, and exposure was higher, in hepatically impaired subjects compared with healthy subjects. In subjects with severe (Child-Pugh C) liver impairment, bazedoxifene mean half-life was 50% longer than that of healthy subjects. Area under the concentration-time curve geometric mean ratios (90%CI) for Child-Pugh A, B, and C liver impairment vs healthy subjects were 243% (156-379), 209% (135-326), and 368% (236-572), respectively. Although there were no severe adverse events in this study, bazedoxifene use in patients with hepatic impairment is not recommended.

AB - BACKGROUND: Empty nose syndrome (ENS) is a debilitating disorder thought to arise as a postsurgical phenomenon from excessive loss of nasal tissues. Affected patients often report a profound impact on all aspects of life, but the extent of this burden has not been quantified. We sought to determine the association of ENS with mental health and functional impairments. METHODS: A cross-sectional study was performed of individuals with ENS recruited from online ENS forums. ENS status was validated based on a positive 6-item Empty Nose Syndrome Questionnaire (ENS6Q) score and sinus computed tomography imaging or supporting medical documentation. Subjects completed the ENS6Q, the 9-item Patient Health Questionnaire (PHQ-9) for depression, the 7-item Generalized Anxiety Disorder questionnaire (GAD-7), the Epworth Sleepiness Scale for daytime somnolence (ESS), the Work Productivity and Impairment questionnaire (WPAI), and the 5-dimension EuroQol General Health State Survey (EQ-5D-5L). Pearson correlation analysis was performed with alpha = 0.05 to determine significance. RESULTS: Fifty-three ENS individuals were included in the study. Overall, participants reported symptoms consistent with moderate anxiety (MU = 12.7; standard deviation [SD], 5.9) and moderately severe depression warranting treatment (MU = 17.9; SD, 6.8). Participants also noted a 62% reduction in productivity at work (n = 24) and 65% in all other activities (n = 53). ENS6Q symptom severity was correlated with more severe depression (p < 0.001), anxiety (p < 0.001), overall pain/discomfort (p = 0.002), and impairment in activities of daily living (p = 0.003). CONCLUSION: ENS individuals carry a clinically significant psychological burden and experience marked difficulties with many activities of daily living. A multimodal approach to address the tissue loss with surgery and cognitive-behavioral therapy for the psychological burden may provide the most optimal outcome. PMID- 29443459 TI - Tunable Bifunctional Activity of Mnx Co3-x O4 Nanocrystals Decorated on Carbon Nanotubes for Oxygen Electrocatalysis. AB - Noble-metal-free electrocatalysts are attractive for cathodic oxygen catalysis in alkaline membrane fuel cells, metal-air batteries, and electrolyzers. However, much of the structure-activity relationship is poorly understood. Herein, the comprehensive development of manganese cobalt oxide/nitrogen-doped multiwalled carbon nanotube hybrids (Mnx Co3-x O4 @NCNTs) is reported for highly reversible oxygen reduction and evolution reactions (ORR and OER, respectively). The hybrid structures are rationally designed by fine control of surface chemistry and synthesis conditions, including tuning of functional groups at surfaces, congruent growth of nanocrystals with controllable phases and particle sizes, and ensuring strong coupling across catalyst-support interfaces. Electrochemical tests reveal distinctly different oxygen catalytic activities among the hybrids, Mnx Co3-x O4 @NCNTs. Nanocrystalline MnCo2 O4 @NCNTs (MCO@NCNTs) hybrids show superior ORR activity, with a favorable potential to reach 3 mA cm-2 and a high current density response, equivalent to that of the commercial Pt/C standard. Moreover, the hybrid structure exhibits tunable and durable catalytic activities for both ORR and OER, with a lowest overall potential of 0.93 V. It is clear that the long-term electrochemical activities can be ensured by rational design of hybrid structures from the nanoscale. PMID- 29443460 TI - Tracking the Sugar Rush: Incorporating Continuous Glucose Monitoring Into Multisite Early Clinical Research With Type 2 Diabetes Subjects. AB - Continuous glucose monitoring (CGM) systems allow patients with diabetes mellitus to closely track glucose concentrations over several days, identify trends in glucose levels, and avoid glucose excursions. This technology has not only advanced diabetes mellitus management but has increased patient safety through greater glycemic awareness. Due to these attributes, CGM is now being applied in therapeutic research as a pharmacodynamic tool to support early clinical drug development programs. However, to date only a handful of studies have utilized CGM in type 2 diabetes mellitus (T2DM) drug development. A potential barrier from fostering greater use of CGM in clinical development may be related to concerns over subject variability. Therefore, we investigated a key consideration when implementing CGM into early clinical research studies: daily variation within patients with T2DM from multiple clinical research units. From 24 patients with T2DM, we observed strong daily reproducibility (Pearson R = 0.86, P < .0001) in CGM results and found that this technique is practical for multisite studies. Altogether, with low daily variability, CGM is a powerful pharmacodynamic tool for drug efficacy and safety monitoring.

PMID- 29443461 TI - Genetic sex assignment in wild populations using genotyping-by-sequencing data: A statistical threshold approach. AB - Establishing the sex of individuals in wild systems can be challenging and often requires genetic testing. Genotyping-by-sequencing (GBS) and other reduced representation DNA sequencing (RRS) protocols (e.g., RADseq, ddRAD) have enabled the analysis of genetic data on an unprecedented scale. Here, we present a novel approach for the discovery and statistical validation of sex-specific loci in GBS data sets. We used GBS to genotype 166 New Zealand fur seals (NZFS, Arctocephalus forsteri) of known sex. We retained monomorphic loci as potential sex-specific markers in the locus discovery phase. We then used (i) a sex-specific locus threshold (SSLT) to identify significantly male-specific loci within our data set; and (ii) a significant sex-assignment threshold (SSAT) to confidently assign sex in silico the presence or absence of significantly male-specific loci to individuals in our data set treated as unknowns (98.9% accuracy for females; 95.8% for males, estimated via cross-validation). Furthermore, we assigned sex to 86 individuals of true unknown sex using our SSAT and assessed the effect of SSLT adjustments on these assignments. From 90 verified sex-specific loci, we developed a panel of three sex-specific PCR primers that we used to ascertain sex independently of our GBS data, which we show amplify reliably in at least two other pinniped species. Using monomorphic loci normally discarded from large SNP data sets is an effective way to identify robust sex-linked markers for nonmodel species. Our novel pipeline can be used to identify and statistically validate monomorphic and polymorphic sex-specific markers across a range of species and RRS data sets.

AB - Odanacatib (ODN), an oral selective inhibitor of cathepsin K, was an investigational agent previously in development for the treatment of osteoporosis. In this phase 1 open-label study, 12 healthy Chinese postmenopausal women received single-dose ODN 50 mg on day 1 and multiple-dose ODN 50 mg once weekly on days 15, 22, 29, and 36 under fasted conditions. Pharmacokinetic (PK) parameters were evaluated on days 1 and 36. Multiple-dose area under the concentration-time profile (AUC0-168h ) and maximum plasma concentration (Cmax ) were compared with historical data from 9 non-Chinese postmenopausal women who also received ODN 50 mg once weekly for 4 weeks. Median time to Cmax (tmax ) was 3 and 4 hours following single- and multiple-dose administration, respectively. The arithmetic mean +/- SD terminal half-life was 81.0 +/- 14.0 and 106.7 +/- 14.4 hours following single- and multiple-dose administration, respectively. Comparison of multiple-dose PK parameters showed that the geometric mean ratios (Chinese/non-Chinese) and 95%CIs for AUC0-168h and Cmax were 0.81 (0.55-1.19) and 0.87 (0.69-1.11), respectively. All adverse events were mild, none were serious, and none led to discontinuation. Single- and multiple-dose PKs of ODN 50 mg in Chinese postmenopausal women were generally similar to those previously reported in non-Chinese postmenopausal women.

This entails reviewing aspects such as the impact of poverty and the lack of access to quality health care, ignored global killers such as Diseases (Infectious diseases-Malaria, HIV/AIDS), Natural Disasters (Earthquakes, Tsunamis, Floods, and Armed Conflict), Health in the Media, and the Involvement of Pharmaceutical Corporations and Medical Research. These issues are challenges to many needless deaths. Global initiatives are not advancing as they should, such as access to drugs and medications, which some are political.

AB - Ethnic minorities in the United States have a higher prevalence of obesity, with higher levels reported in Latinos/Hispanics. A qualitative study was done to understand perceptions of obesity and identify factors that may enhance the attractiveness of a behavioral weight-loss intervention in the Latino community. Weight loss trials designed to target the Latino/Hispanic population may benefit by considering the Latino/Hispanic perception of the problem, the barriers to weight loss, and for study participation that may be specific to this population.

AB - This research was conducted to identify the acculturation and health behaviors in the African Immigrant population, which is presently living in the United States. Ten studies met the criteria and included health behaviors of status, access to health care, psychiatric services, prostate cancer, morbidity and mortality, HIV knowledge and beliefs, perceptions of suicide, smoking, and obesity. Acculturation was measured using the most common social constructs that influenced the health behaviors of nativity, English (language proficiency), age at immigration, education and socioeconomic status, religion, age at immigration, and length of stay in the U.S. More research is needed to assist in prioritizing the health conditions that need intervention in serving this particular population.

AB - Research suggests that youth aging out of foster care may be at higher risk of experiencing homelessness than other youth. Among this already at-risk population there may be certain characteristics that further exacerbate the risk. This paper uses data collected from various local and state agencies to further examine significant predictors of homelessness among youth who have aged out of foster care. PMID- 29443472 TI - Housing Trajectories for Youth Transitioning from Foster Care: Gender Differences from 2010-2014. AB - This study focuses on longitudinal housing trends for males and females among transitional youth who were participants of a transitional living program (2010 to 2014). Results indicate that young women were more likely to transition to secure independent housing than young men. Demographic characteristics, education, and employment predicted time to secure independent housing. Additionally, results indicate that more highly educated young women transitioned to independence at a faster rate than young men with lower education status.

AB - Using a mixed-methods methodological approach, the proposed study examines the associations between economic well-being and independent living experiences in foster youth. Quantitative data were collected from N = 294 in-care foster youth using the Casey Life Skills assessment (alpha = .79 to alpha = .95). Qualitative data were collected via focus groups with aged-out foster youth (N =15). Results provide important insights on youth's economic well-being, financial literacy, individual experiences regarding aging out of foster care and independent living. This study provides new insights into the complex dynamics of successfully transitioning out of foster care and the need for supporting economic well-being in foster youth to better prepare them to live independently and develop coping skills for the challenges they might experience once they leave the system.

AB - This article presents preliminary findings from an impact study that drew upon administrative data collected by city agencies and data collected by a supportive housing program for young adults who are aging out of foster care, homeless, or at risk of homelessness. Participation in the program was associated with a reduction in shelter use and jail stays during the two years after program entry. The study demonstrates the benefits of collaboration and the possibilities of using administrative data from multiple public agencies to evaluate program impacts on young adult outcomes.

AB - The quality and safety of the home environment is a common focus of Child Protective Services (CPS) investigations.Yet little is known about whether such conditions influence CPS outcomes. The present study uses a sample of low-income families to assess the relative importance of housing conditions and other common risk and protective factors associated with child maltreatment. Results show that hazardous conditions predict investigated child neglect, but not physical abuse or indicated reports. PMID- 29443476 TI - Housing Matters for Families: Promising Practices from Child Welfare Agencies. AB - There is growing acknowledgement that housing can provide more than shelter, a basic need. Housing can also act as a foundation, helping families stay together.The provision of housing as a prevention or protective strategy against child maltreatment has not been widely used by child welfare agencies. A small subset of child welfare agencies across the country, however, is incorporating housing into their response to cases of child abuse and neglect. Using qualitative data from ongoing studies of HUD's Family Unification Program (FUP) and the Children's Bureau supportive housing demonstration for high-need child welfare involved families, we describe some of the promising practices agencies are implementing and testing. Though evaluations of these programs are not yet complete, there is a lot the field can learn from these approaches. This paper provides an overview of seven promising strategies: (1) partnering with public housing agencies and leveraging resources; (2) assessing the housing needs of child welfare involved families; (3) triaging and providing housing resources based on needs; (4) providing housing first, not. last; (5) developing housing stability plans and shared case plans; (6) screening families into housing, rather than screening out; and (7) providing housing search assistance.

AB - This paper describes Connecticut's Supportive Housing for Families (SHF) program, which is one of five national sites comprising a federally- funded demonstration of housing and child welfare. Evaluations of supportive housing (SH) interventions are complicated by contextual factors that make it difficult to isolate their effects. 'Ihese and other challenges complicate efforts to conduct rigorous research and establish external validity, and to date, few studies examine the impact of SH interventions for child- welfare involved families. We describe retrospectively the development of SHF using. six stages of imple- mentation articulated within an implementation science framework, noting both the core components of the program and its expansion from a small pilot exploration, to a statewide initiative, and now to the center of a systems change effort with potential to influence national policy and implementation.

AB - The study tests the short-term impact on housing stability of the Family Unification Program (FUP), a permanent housing program for child welfare- involved families at risk of separation from children due to inadequate housing. Families eligible for FUP (n = 150) received housing case management services as usual, and half were referred for permanent housing vouchers made available through FUP. Families referred for FUP secured more enriched home learning environments, while more precariously housed families exhibited greater housing, stability when referred for FUP. The intervention did not relate with housing affordability or improvements in neighborhood quality. Findings suggest benefits of FUP-especially for more vulnerable families--in key areas that support child developmet; however, families continue to struggle in the context of poverty. PMID- 29443479 TI - Family Stability and Child Welfare Involvement among Families Served in Permanent Supportive Housing. AB - This article examines the effectiveness of supportive housing in fostering family preservation and reunification for homeless families with multiple housing barriers. Results indicate that more thanhalfofthe supportive housing program families who are separated from their families by Child Protective Services prior to entering the program are reunified during the 12-month period after entering housing. The rate of reunification for supportive housing families is significantly higher than the rate for matched families who enter shelters, but not significantly different than the rate experienced by matched families entering public housing. This study provides encouraging evidence that housing for families in the child welfare system, including but necessarily limited to supportive housing, can facilitate the reunification of children.

PMID- 29443482 TI - The Psychohistory of Child Maltreatment Among Antebellum Slaveholders: Part II. AB - In the psychohistory of the antebellum South, the extent of child abuse in slaveholder families is important for understanding how members of the southern elite were reared and the extent to which they were infected with the toxic residue of their elders' passions and rages. It is argued that the Old South was a developing region, rather than an already developed one. Consequently, the rate of child abuse that is characteristic of contemporary postindustrial societies is not the proper paradigm for conceptualizing the abuse rate in slaveholder families. It is proposed instead that the rate of child abuse in contemporary developing societies is a better fit for estimating abuse in the antebellum South. Societal and familial variables impinging on the abuse of slaveholder children-corporal punishment, alcohol consumption, hyper-masculinity, a traumatogenic culture of violence, wife abuse, maternal ambivalence and neglect, miscegenation and incest are discussed, as is the likelihood of maltreatment by slaves. Using a study of child abuse across 28 nations, tentative rates of abuse are proposed. PMID- 29443483 TI - John Woolman and Ethical Progress in Kitcher's Pragmatic Naturalism. AB - The development of John Woolman's views on slavery plays an important evidentiary role in Philip Kitcher's recent book, The ethical project (Kitcher 2011). In this work Kitcher takes what he calls a "pragmatic naturalist" approach to ethics and claims that the discovery of ethical truth plays no role in the emergence of ethical progress. To support his view, he argues that Woolman's contribution was not due to his discovery of an ethical truth about slavery, not previously known, but due to his sensitivity to slavery and his influence on others, which contributed to collective progressive change in moral norms involving slavery. While not disputing Kitcher's ethical theory, I argue that personal discoveries of a moral psychological nature made by Woolman served both as insights and motivations for his contribution. Thus, even if there are no such things as independent ethical truths that can be discovered by individuals, a fully naturalistic approach to ethical progress requires that we make room not only for group-level progressive evolution of norms, but also for individual discoveries of a moral psychological nature that can sometimes cause an individual to play a significant initiating role in progressive ethical transitions that occur at a group level. PMID- 29443484 TI - Youth self-report of child maltreatment in representative surveys: a systematic review. AB - INTRODUCTION: This systematic review identified population-representative youth surveys containing questions on self-reported child maltreatment. Data quality and ethical issues pertinent to maltreatment data collection were also examined. METHODS: A search was conducted of relevant online databases for articles published from January 2000 through March 2016 reporting on population representative data measuring child maltreatment. Inclusion criteria were established a priori; two reviewers independently assessed articles to ensure that the criteria were met and to verify the accuracy of extracted information. RESULTS: A total of 73 articles reporting on 71 surveys met the inclusion criteria. A variety of strategies to ensure accurate information and to mitigate survey participants' distress were reported. CONCLUSION: The extent to which efforts have been undertaken to measure the prevalence of child maltreatment reflects its perceived importance across the world. Data on child maltreatment can be effectively collected from youth, although our knowledge of best practices related to ethics and data quality is incomplete. PMID- 29443485 TI - Effectiveness of the CANRISK tool in the identification of dysglycemia in First Nations and Metis in Canada. AB - INTRODUCTION: First Nations/Metis populations develop diabetes earlier and at higher rates than other Canadians. The Canadian diabetes risk questionnaire (CANRISK) was developed as a diabetes screening tool for Canadians aged 40 years or over. The primary aim of this paper is to assess the effectiveness of the existing CANRISK tool and risk scores in detecting dysglycemia in First Nations/Metis participants, including among those under the age of 40. A secondary aim was to determine whether alternative waist circumference (WC) and body mass index (BMI) cut-off points improved the predictive ability of logistic regression models using CANRISK variables to predict dysglycemia. METHODS: Information from a self-administered CANRISK questionnaire, anthropometric measurements, and results of a standard oral glucose tolerance test (OGTT) were collected from First Nations and Metis participants (n = 1479). Sensitivity and specificity of CANRISK scores using published risk score cut-off points were calculated. Logistic regression was conducted with alternative ethnicity-specific BMI and WC cut-off points to predict dysglycemia using CANRISK variables. RESULTS: Compared with OGTT results, using a CANRISK score cut-off point of 33, the sensitivity and specificity of CANRISK was 68% and 63% among individuals aged 40 or over; it was 27% and 87%, respectively among those under 40. Using a lower cut-off point of 21, the sensitivity for individuals under 40 improved to 77% with a specificity of 44%. Though specificity at this threshold was low, the higher level of sensitivity reflects the importance of the identification of high risk individuals in this population. Despite altered cut-off points of BMI and WC, logistic regression models demonstrated similar predictive ability. CONCLUSION: CANRISK functioned well as a preliminary step for diabetes screening in a broad age range of First Nations and Metis in Canada, with an adjusted CANRISK cutoff point for individuals under 40, and with no incremental improvement from using alternative BMI/WC cut-off points. PMID- 29443487 TI - John F. Kennedy, Jr. and the Torn Self: A Psychological Portrait. AB - John F. Kennedy, Jr., (1960-1999) was one of the most recognizable figures of the 2nd half of the 20th century. He died tragically in an airplane he was piloting on route to Hyannis Port, Massachusetts to attend the wedding of his cousin, Rory Kennedy. Though much has been written about the life of J.F.K., Jr., this article represents the first psychobiographical portrait of the iconic personality. Employing a multi-theoretical approach to psychobiography, this profile integrates psychodynamic theory (James 1902/1982, Winnicott 1965), psychosocial development theory (Erikson 1950, 1980), and a modern theory of emerging adulthood (Arnett 2004) to develop a deep psychological portrait of the beloved son of President John F. Kennedy and Jacqueline Kennedy Onassis. J.F.K., Jr.'s life is traced along the four developmental periods of infancy and childhood, high school and college, emerging adulthood, and young adulthood. Psychobiography often focuses on unsolved mysteries in the lives of historic figures, and this profile of J.F.K., Jr., explores his search for his unique identity, whether he would have entered political life, and the likely future of his life with Carolyn Bessette Kennedy had they lived.

AB - INTRODUCTION: In 2011, the Agence de la sante et des services sociaux de Montreal (ASSSM), in partnership with the region's Centres de sante et de services sociaux (CSSS), coordinated the implementation of a program on cardiometabolic risk based on the Chronic Care Model. The program, intended for patients suffering from diabetes or hypertension, involved a series of individual follow-up appointments, group classes and exercise sessions. Our study assesses the impact on patient health outcomes of variations in the implementation of some aspects of the program among the six CSSSs taking part in the study. METHODS: The evaluation was carried out using a quasi-experimental "before and after" design. Implementation variables were constructed based on data collected during the implementation analysis regarding resources, compliance with the clinical process set out in the regional program, the program experience and internal coordination within the care team. Differences in differences using propensity scores were calculated for HbA1c results, achieving the blood pressure (BP) target, and two lifestyle targets (exercise level and carbohydrate distribution) at the 6- and 12-month follow-ups, based on greater or lesser patient exposure to the implementation of various aspects of the program under study. RESULTS: The results focus on 1185 patients for whom we had data at the 6-month follow- up and the 992 patients from the 12-month follow-up. The difference in differences analysis shows no clear association between the extent of implementation of the various aspects of the program under study and patient health outcomes. CONCLUSION: The program produces effects on selected health indicators independent of variations in program implementation among the CSSSs taking part in the study. The results suggest that the effects of this type of program are more highly dependent on the delivery of interventions to patients than on the organizational aspects of its implementation.

AB - We demonstrate the generation of block copolymer (BCP) line patterns oriented orthogonal to a very small (minimal) topographic trench pattern over arbitrarily large areas using solvent-vapor annealing. Increasing the thickness of BCP films induced an orthogonal alignment of the BCP cylindrical microdomains, where full orthogonal alignment of the cylindrical microdomains with respect to the trench direction was obtained at a film thickness corresponding to 1.70 L0. A capillary flow of the solvent across the trenches was a critical factor in the alignment of the cylindrical microdomains. Grazing incidence small-angle X-ray scattering was used to determine the orientation function of the microdomains, with a value of 0.997 being found reflecting a nearly perfect orientation. This approach to produce orthogonally aligned BCP line patterns could be extended to the nanomanufacturing and fabrication of hierarchical nanostructures.

AB - Strontium segregation at perovskite surfaces deteriorates the oxygen reduction reaction kinetics of cathodes and therefore the long-term stability of solid oxide fuel cells (SOFCs). For the systematic and quantitative assessment of the elastic energy in perovskite oxides, which is known to be one of the main origins for dopant segregation, we report the fractional free volume as a new descriptor for the elastic energy in the perovskite oxide system. To verify the fractional free volume model, three samples were prepared with different A-site dopants: La0.6Sr0.4CoO3-delta, La0.6Sr0.2Ca0.2CoO3-delta, and La0.6Ca0.4CoO3-delta. A combination of the theoretical calculations of the segregation energy and oxide formation energy and experimental measurements of the structural, chemical, and electrochemical degradation substantiated the validity of using the fractional free volume to predict the dopant segregation. Furthermore, the dopant segregation could be significantly suppressed by increasing the fractional free volume in the perovskite oxides with dopant substitution. Our results provide insight into dopant segregation from the elastic energy perspective and offer a design guideline for SOFC cathodes with enhanced stability at elevated temperatures.

AB - A new atomic layer deposition (ALD) process for depositing nickel carbide (Ni3C x) thin films is reported, using bis( N, N'-di- tert butylacetamidinato)nickel(II) and H2 plasma. The process shows a good layer-by layer film growth behavior with a saturated film growth rate of 0.039 nm/cycle for a fairly wide process temperature window from 75 to 250 degrees C. Comprehensive material characterizations are performed on the Ni3C x films deposited at 95 degrees C with various H2 plasma pulse lengths from 5 to 12 s, and no appreciable difference is found with the change of the plasma pulse length. The deposited Ni3C x films are fairly pure, smooth, and conductive, and the x in the nominal formula of Ni3C x is approximately 0.7. The ALD Ni3C x films are polycrystalline with a rhombohedral Ni3C crystal structure, and the films are free of nanocrystalline graphite or amorphous carbon. Last, we demonstrate that, by using this ALD process, highly uniform Ni3C x films can be conformally deposited into deep narrow trenches with an aspect ratio as high as 20:1, which thereby highlights the broad and promising applicability of this process for conformal Ni3C x film coatings on complex high-aspect-ratio 3D architectures in general. PMID- 29443493 TI - Scalable Inkjet-Based Structural Color Printing by Molding Transparent Gratings on Multilayer Nanostructured Surfaces. AB - To enable customized manufacturing of structural colors for commercial applications, up-scalable, low-cost, rapid, and versatile printing techniques are highly demanded. In this paper, we introduce a viable strategy for scaling up production of custom-input images by patterning individual structural colors on separate layers, which are then vertically stacked and recombined into full-color images. By applying this strategy on molded-ink-on-nanostructured-surface printing, we present an industry-applicable inkjet structural color printing technique termed multilayer molded-ink-on-nanostructured-surface (M-MIONS) printing, in which structural color pixels are molded on multiple layers of nanostructured surfaces. Transparent colorless titanium dioxide nanoparticles were inkjet-printed onto three separate transparent polymer substrates, and each substrate surface has one specific subwavelength grating pattern for molding the deposited nanoparticles into structural color pixels of red, green, or blue primary color. After index-matching lamination, the three layers were vertically stacked and bonded to display a color image. Each primary color can be printed into a range of different shades controlled through a half-tone process, and full colors were achieved by mixing primary colors from three layers. In our experiments, an image size as big as 10 cm by 10 cm was effortlessly achieved, and even larger images can potentially be printed on recombined grating surfaces. In one application example, the M-MIONS technique was used for printing customizable transparent color optical variable devices for protecting personalized security documents. In another example, a transparent diffractive color image printed with the M-MIONS technique was pasted onto a transparent panel for overlaying colorful information onto one's view of reality.

PMID- 29443495 TI - Dynamic Sliding Enhancement on the Friction and Adhesion of Graphene, Graphene Oxide, and Fluorinated Graphene. AB - Graphene and functionalized graphene are promising candidates as ultrathin solid lubricants for dealing with the adhesion and friction in micro- and nanoelectromechanical systems (MEMS and NEMS). Here, the dynamic friction and adhesion characteristics of pristine graphene (PG), graphene oxide (GO), and fluorinated graphene (FG) were comparatively studied using atomic force microscopy (AFM). The friction as a function of load shows nonlinear characteristic on GO with strong adhesion and linear characteristic on PG and FG with relatively weak adhesions. An adhesion enhancement phenomenon that the slide off force after dynamic friction sliding is larger than the pull-off force is observed. The degree of adhesion enhancement increases with the increasing surface energy, accompanied by a corresponding increase in transient friction strengthening effect. The dynamic adhesion and friction enhancements are attributed to the coupling of dynamic tip sliding and surface hydrophilic properties. The atomic-scale stick-slip behaviors confirm that the interfacial interaction is enhanced during dynamic sliding, and the enhancing degree depends on the surface hydrophilic properties. These findings demonstrate the adhesive strength between the contact surfaces can be enhanced in the dynamic friction process, which needs careful attention in the interface design of MEMS and NEMS. PMID- 29443496 TI - Inert C-H Bond Transformations Enabled by Organometallic Manganese Catalysis. AB - Traditional organic synthesis relies heavily on the transformations of various preinstalled functional groups, such as cross-coupling reactions using organohalides and organometallic reagents. The strategy of C-H activation enables the direct formation of C-C/C-X (X = heteroatom) bonds from inert C-H bonds, which can enhance the atom- and step-economy of organic synthesis. To date, precious metals have overwhelmingly dominated the C-H activation field; however, the rarity and high cost of these metals necessitate the development of more sustainable catalysts. In this regard, catalysts based on manganese are highly desirable owing to the abundant reserve of manganese in the earth's crust and its economic benefits, low toxicity, and potentially unique reactivity. Although the first stoichiometric manganese-mediated C-H activation reaction was reported as early as 1970, manganese-catalyzed C-H activation reactions are largely underdeveloped. How to construct an efficient catalytic cycle for manganese in C H activation reactions remains as a key issue to be addressed. In this Account, we summarize our recent advances in the manganese-catalyzed transformations of inert C-H bonds. To overcome the challenges associated with building manganese based catalytic cycles, we developed two novel strategies, namely, synergy between manganese catalysts and bases and between manganese catalysts (with or w/o bases) and acids. By implementing the former strategy, we developed cooperative manganese/base catalytic systems that facilitate a new mode of C-H bond activation by manganese via a redox-neutral base-assisted deprotonation mechanism. As such, the requirement for the tedious preparation of MnR(CO)5 complexes (R = Me, Bn, Ph) in stoichiometric reactions was eliminated, and a series of manganese-catalyzed C-H activation reactions of arenes with various reaction partners having C=C and C?C bonds were achieved. Through the latter strategy of synergy between manganese catalysts (with or w/o bases) and acids, we disclosed a "dual activation" mode for performing manganese-catalyzed C-H bond transformations, that is, merging C-H activation by manganese catalysts and C-X multiple bond activation by Lewis acids. Consequently, the scope of C-H substrates could be expanded to include challenging ketones and olefinic C-H compounds. Additionally, the range of reaction partners could be significantly broadened to include those bearing more polarized C?O, C?N, and C=N bonds such as aldehydes, imines, and nitriles. Remarkably, the innate reactivity of different C H bonds in ketones could be reversed by manganese catalysis, and the reactions could even be carried out at room temperature. Our findings provide guiding information for the future development of manganese-catalyzed C-H activation reactions and beyond. Related important contributions from other groups are mentioned, and the remaining challenges and future perspective in this emerging area are also presented. PMID- 29443497 TI - Prediction of Drug-Induced Nephrotoxicity with a Hydroxyl Radical and Caspase Light-Up Dual-Signal Nanoprobe. AB - The development of well-designed nanoprobes for specific imaging of multiple biomarkers in renal cells will afford beneficial information related to the transmutation process of drug-induced kidney injury (DIKI). However, the most reported nanoprobes for DIKI detection were dependent on single-signal output and lack of kidney targeting. In this work, we reported a renal cell targeting and dual-signal nanoprobe by encapsulating Brite 670 and Dabcyl-KFFFDEVDK-FAM into a low molecular weight chitosan nanoparticle. Confocal fluorescence imaging results demonstrated that the nanoprobe could visualize the upregulation of hydroxyl radical in early stage and activation of caspase-3 in late stage of DIKI at both the renal cell and tissue level. In a mouse DIKI model, the positive time of 8 h using nanoprobe imaging was superior to that of 72 h for serum creatinine or blood urea nitrogen, 16 h for cystatin-C, and 24 h for kidney injury molecule-1 with conventional methods. These results demonstrated that the nanoprobe may be a promising tool for effective early prediction and discriminative imaging of DIKI. PMID- 29443498 TI - Spectrally Resolved and Functional Super-resolution Microscopy via Ultrahigh Throughput Single-Molecule Spectroscopy. AB - As an elegant integration of the spatial and temporal dimensions of single molecule fluorescence, single-molecule localization microscopy (SMLM) overcomes the diffraction-limited resolution barrier of optical microscopy by localizing single molecules that stochastically switch between fluorescent and dark states over time. While this type of super-resolution microscopy (SRM) technique readily achieves remarkable spatial resolutions of ~10 nm, it typically provides no spectral information. Meanwhile, current scanning-based single-location approaches for mapping the positions and spectra of single molecules are limited by low throughput and are difficult to apply to densely labeled (bio)samples. In this Account, we summarize the rationale, design, and results of our recent efforts toward the integration of the spectral dimension of single-molecule fluorescence with SMLM to achieve spectrally resolved SMLM (SR-SMLM) and functional SRM ( f-SRM). By developing a wide-field scheme for spectral measurement and implementing single-molecule fluorescence on-off switching typical of SMLM, we first showed that in densely labeled (bio)samples it is possible to record the fluorescence spectra and positions of millions of single molecules synchronously within minutes, giving rise to ultrahigh-throughput single-molecule spectroscopy and SR-SMLM. This allowed us to first show statistically that for many dyes, single molecules of the same species exhibit near identical emission in fixed cells. This narrow distribution of emission wavelengths, which contrasts markedly with previous results at solid surfaces, allowed us to unambiguously identify single molecules of spectrally similar dyes. Crosstalk-free, multiplexed SRM was thus achieved for four dyes that were merely 10 nm apart in emission spectrum, with the three-dimensional SRM images of all four dyes being automatically aligned within one image channel. The ability to incorporate single-molecule fluorescence measurement with SMLM was next utilized to achieve f-SRM. By encoding functional information into the spectral responses of environment-sensing fluorescent probes, f-SRM transcends the structural information provided by typical SRM techniques and reveals the spatiotemporal distribution of physicochemical parameters with single-molecule sensitivity and nanoscale spatial resolution. As one example, by employing the solvatochromic dye Nile Red to sense local chemical polarity, we revealed nanoscale heterogeneity in the membranes of live mammalian cells. This enabled us to unveil substantial polarity differences between the plasma membrane and the membranes of nanoscale intracellular organelles, a result we determined to be due to differences in local cholesterol levels. With the addition of cholesterol or cholera toxin, we further observed the formation of low-polarity, raftlike nanodomains in the plasma membrane. In another study, we generalized SR-SMLM to fluorogenic single molecule reactions. As a wide-field technique, SR-SMLM readily captures the emission spectra of individual product fluorescent molecules that are stochastically produced from nonfluorescent reactants at random locations over large sample areas, and therefore, it provides the unique possibility to spectrally identify and characterize single product molecules in a high throughput fashion. Using the ring-opening reaction of a photochromic spiropyran as an example, we demonstrated that the capability to resolve the emission spectra of single product molecules could unveil rich, multipath reaction pathways. In summary, by integrating the spatial, temporal, and spectral dimensions of single-molecule fluorescence, SR-SMLM and f-SRM add rich spectral and functional dimensions to SRM and thus open up new ways of probing biological and chemical systems at the single-molecule and nanoscale levels.

AB - We synthesize and characterize stimulus-responsive nanocomposites consisting of poly( N-isopropylacrylamide) (PNIPAM) with controlled loadings of anisotropic plate-like silver nanoprisms. These composites show strong, reversible switching of their optical extinction and scattering properties in response to temperature cycling. We use UV-vis-NIR spectroscopy and dynamic light scattering to characterize the hybrids and show that the loading density of the silver nanoprisms in the polymer and the size of the nanoprisms are both factors that can be used to tailor the optical response of the composites, extending the range of colors beyond that previously reported with PNIPAM/plasmonic nanoparticle composites. These PNIPAM/silver nanoprism hybrids exhibit thermochromic shifts that are 5-10 times larger than those typically reported for similar structures of PNIPAM composites with silver nanoparticles of a comparable range of loading density. In addition, we show that these composites can exhibit very large ratiometric changes in scattering in the NIR, which could open applications for related materials in thermal management and NIR labeling and taggants.

For specific biomolecular recognition to be realized for diagnosis and imaging, the key lies in developing a stable and easy-to-use bioconjugation method for antibody modification. Current methods are not yet satisfactory regarding conjugation time, stability, and binding efficiency. Here, we report a facile and high-yield approach based on a bispecific antibody (BsAb) free of chemical reaction steps. One end of the BsAb is designed to recognize methoxy polyethylene glycol-coated UCNPs, and the other end of the BsAb is designed to recognize the cancer antigen biomarker. Through simple vortexing, BsAb-UCNP nanoprobes form within 30 min and show higher (up to 54%) association to the target than that of the traditional UCNP nanoprobes in the ELISA-like assay. We further demonstrate its successful binding to the cancer cells with high efficiency and specificity for background-free fluorescence imaging under near infrared excitation. This method suggests a general approach broadly suitable for functionalizing a range of nanoparticles to specifically target biomolecules.

AB - We report a magnetically actuated peanut-shaped hematite colloid motor that can not only move in a rolling or wobbling mode in fluids but also perform single cell manipulation and patterning in a noncontact way. The peanut motor in a rolling mode can reach a maximal velocity of 10.6 MUm s-1 under a rotating magnetic field of 130 Hz and 6.3 mT and achieve a more precisely controllable motion in predefined tracks. While in a wobbling mode, the motor reaches a maximal velocity of 14.5 MUm s-1 under a conical rotating magnetic field of 80 Hz and 6.3 mT and can climb over steep slopes to adapt the motor for more complex environments. The fluid flow simulation results reveal that the difference between two movement modes mostly comes from the distribution discrepancy of the flow fields near the motors. Through the integration of the rolling and wobbling movement, these peanut motors can autonomously transport and release cells to a predefined site and thus form complex cell patterns without a physical contact. Such magnetically actuated peanut colloid motors afford a biofriendly technique for manipulation and patterning of cells, cell measurements, and intracellular communication investigations. PMID- 29443502 TI - Direct Classification of GC * GC-Analyzed Complex Mixtures Using Non-Negative Matrix Factorization-Based Feature Extraction. AB - Complex chemical mixtures need to be evaluated to, for example, aid in medical diagnoses, assess product quality, and assess environmental conditions. Two dimensional gas chromatography (GC * GC), which is a comprehensive analytical technique, combined with data classification techniques, has attracted great interest for assessing mixtures. In this study, a nontarget cross-sample analysis based unsupervised direct classification method using non-negative matrix factorization was developed for assessing mixtures analyzed by GC * GC. The method was developed using GC * GC data for more than 30 river water samples as image data. The retention time shift correction data processing step was important to the classification accuracy because the compound signals were found at slightly different times for different samples. The maximum likelihood estimates of the matching ratios for the 30 samples, with retention time shift correction, were 86.8% and 77.0% using two and three ranks, respectively. The method is easy to perform and intuitive, requiring no specific knowledge or labeled data. This direct classification method will therefore be particularly useful for performing initial screens of large numbers of samples and for identifying major differences between samples. PMID- 29443503 TI - Dual-Color Bioluminescent Sensor Proteins for Therapeutic Drug Monitoring of Antitumor Antibodies. AB - Monitoring the levels of therapeutic antibodies in individual patients would allow patient-specific dose optimization, with the potential for major therapeutic and financial benefits. Our group recently developed a new platform of bioluminescent sensor proteins (LUMABS; LUMinescent AntiBody Sensor) that allow antibody detection directly in blood plasma. In this study, we targeted four clinically important therapeutic antibodies, the Her2-receptor targeting trastuzumab, the anti-CD20 antibodies rituximab and obinutuzumab, and the EGFR blocking cetuximab. A strong correlation was found between the affinity of the antibody binding peptide and sensor performance. LUMABS sensors with physiologically relevant affinities and decent sensor responses were obtained for trastuzumab and cetuximab using mimotope and meditope peptides, respectively, with affinities in the 10-7 M range. The lower affinity of the CD20-derived cyclic peptide employed in the anti-CD20 LUMABS sensor ( Kd = 10-5 M), translated in a LUMABS sensor with a strongly attenuated sensor response. The trastuzumab and cetuximab sensors were further characterized with respect to binding kinetics and their performance in undiluted blood plasma. For both antibodies, LUMABS based detection directly in plasma compared well to the analytical performance of commercial ELISA kits. Besides identifying important design parameters for the development of new LUMABS sensors, this work demonstrates the potential of the LUMABS platform for point-of-care detection of therapeutic antibodies. PMID- 29443504 TI - Ion Source Multiplexing on a Single Mass Spectrometer. AB - We present the simple approach for the combination of different ion sources on a single mass spectrometer without any interference between them. Each ion source can be positioned as far as 1 m from the mass spectrometer; ions are transported by the means of flexible copper tubes, which are connected, to the separate inlet capillaries. Special valves enable switching channels on and off. Using this approach, we successfully combined native electrospray ionization (ESI), regular ESI, beta-electrons ionization, and atmospheric pressure photoionization (APPI) of thermally desorbed vapors of petroleum on a single mass spectrometer. In addition, separate channels allow infusing internal calibration mixture or performing ion molecular reactions in one channel and using the other as a reference. Using this idea, we have developed an original sequential window acquisition of all theoretical mass spectra (SWATH MS) approach in which peptide ions are transported in different channels, one of which is heated to high temperature so that ions are thermally fragmented, and the other channel ensures the presence of nonfragmented ions in the spectrum. Also, we demonstrated the possibility to perform gas phase H/D exchange reaction in one channel and using another as reference. Use of valves makes it possible to exclude any interference between them. Thus, we have demonstrated the possibility to create a multichannel system in which ions would be transported through several inlet tubes in which different ion molecular reactions such as Paterno-Buchi, ozonation, or H/D exchange will occur. Comparison of mass spectra recorded when different channels are open will provide structural and chemical information about unknown species. PMID- 29443505 TI - Cellulose Depolymerization over Heterogeneous Catalysts. AB - Cellulosic biomass is the largest source of renewable organic carbon on our planet. Cellulose accounts for 40-50 wt % of this lignocellulose, and it is a feedstock for industrially important chemicals and fuels. The first step in cellulose conversion involves its depolymerization to glucose or to its hydrogenated product sorbitol. The hydrolysis of cellulose to glucose by homogeneous mineral acids was the subject of research for almost a century. However, homogeneous acids have significant drawbacks and are neither economical nor environmentally friendly. In 2006, our group reported for the first time the ability of heterogeneous catalysts to depolymerize cellulose through hydrolytic hydrogenation to produce sorbitol. Later, we reported the hydrolysis of cellulose to glucose using carbon catalyst containing weakly acidic functional groups. Understanding the reaction between cellulose and heterogeneous catalyst is a challenge as the reaction occurs between a solid substrate and a solid catalyst. In this Account, we describe our efforts for the conversion of cellulose to sorbitol and glucose using heterogeneous catalysts. Sorbitol is produced by sequential hydrolysis and hydrogenation of cellulose in one pot. We reported sorbitol synthesis from cellulose in the presence of supported metal catalysts and H2 gas. The reducing environment of the reaction prevents byproduct formation, and harsh reaction conditions can be used to achieve sorbitol yield of up to 90%. Glucose is produced by acid catalyzed hydrolysis of cellulose, a more challenging reaction owing to the tendency of glucose to rapidly decompose in hot water. Sulfonated carbons were first reported as active catalysts for cellulose hydrolysis, but they were hydrothermally unstable under the reaction conditions. We found that carbon catalysts bearing weakly acidic functional groups such as hydroxyl and carboxylic acids are also active. Weakly acidic functional groups are hydrothermally stable, and a soluble sugar yield of 90% was achieved in a 20 min reaction. We clarified that the polycyclic aromatic surface of the carbon adsorbs cellulose molecules on its surface by CH-pi and hydrophobic interactions driven by a positive change in entropy of the system. The adsorbed molecules are rapidly hydrolyzed by active sites containing vicinal functional groups that recognize the hydroxyl groups on cellulose to achieve a high frequency factor. This phenomenon is analogous to the hydrolysis of cellulose by enzymes that use CH-pi and hydrophobic interactions along with weakly acidic carboxylic acid and carboxylate pair to catalyze the reaction. However, in comparison with enzymes, carbon catalyst is functional over a wide range of pH and temperatures. We also developed a continuous flow slurry process to demonstrate the feasibility for commercial application of carbon-catalyzed cellulose hydrolysis to glucose using inexpensive catalyst prepared by air oxidation. We believe that further efforts in this field should be directed toward eliminating roadblocks for the commercialization of cellulose conversion reactions.

AB - Peptoids are peptide-mimetic biopolymers that are easy to synthesize and adaptable for use in drugs, chemical scaffolds, and coatings. However, there is insufficient information about their structural preferences and interactions with the environment in various applications. We conducted a study to understand the fundamental differences between peptides and peptoids using molecular dynamics simulations with semiempirical (PM6) and empirical (AMBER) potentials, in conjunction with metadynamics enhanced sampling. From studies of single molecules in water and on surfaces, we found that sarcosine (model peptoid) is much more flexible than alanine (model peptide) in different environments. However, the sarcosine and alanine interact similarly with a hydrophobic or a hydrophilic. Finally, this study highlights the conformational landscape of peptoids and the dominant interactions that drive peptoids toward these conformations. PMID- 29443507 TI - Three-Dimensional Directionality Is a Pivotal Structural Feature for the Bioactivity of Azabisphosphonate-Capped Poly(PhosphorHydrazone) Nanodrug Dendrimers. AB - Dendrimers are nanosized, nonlinear, hyperbranched polymers whose overall 3D shape is key for their biological activity. Poly(PhosphorHydrazone) (PPH) dendrimers capped with aza-bisphosphonate (ABP) end groups are known to have anti inflammatory properties enabling the control of inflammatory diseases in different mouse models. Here we screen the anti-inflammatory activity of a series of PPH dendrimers bearing between 2 and 16 ABP end groups in a mouse model of arthritis and confront the biological results with atomistic simulations of the dendrimers. We show that only the PPH dendrimers capped with 10 and 12 ABP end groups can control the flare of the inflammatory disease. All-atom accelerated molecular dynamics simulations show that dendrimers with a low number of ABP end groups are directional but highly flexible/dynamic and have thereby limited efficiency in establishing multivalent interactions. The largest dendrimer appears as nondirectional, having 16 ABP end groups forming patches all over the dendrimer surface. Conversely, intermediate dendrimers having 10 or 12 ABP end groups reach the best compromise between the number of surface groups and their stable directional gathering, a real maximization of multivalency. PMID- 29443508 TI - Development of an Infection-Responsive Fluorescent Sensor for the Early Detection of Urinary Catheter Blockage. AB - Formation of crystalline biofilms following infection by Proteus mirabilis can lead to encrustation and blockage of long-term indwelling catheters, with serious clinical consequences. We describe a simple sensor, placed within the catheter drainage bag, to alert of impending blockage via a urinary color change. The pH responsive sensor is a dual-layered polymeric "lozenge", able to release the self quenching dye 5(6)-carboxyfluorescein in response to the alkaline urine generated by the expression of bacterial urease. Sensor performance was evaluated within a laboratory model of the catheterized urinary tract, infected with both urease positive and negative bacterial strains under conditions of established infection, achieving an average "early warning" of catheter blockage of 14.5 h. Signaling only occurred following infection with urease positive bacteria. Translation of these sensors into a clinical environment would allow appropriate intervention before the occurrence of catheter blockage, a problem for which there is currently no effective control method. PMID- 29443510 TI - De Novo Glycan Sequencing by Electronic Excitation Dissociation and Fixed-Charge Derivatization. AB - Detailed glycan structural characterization is frequently achieved by collisionally activated dissociation (CAD) based sequential tandem mass spectrometry (MS n) analysis of permethylated glycans. However, it is challenging to implement MS n ( n > 2) during online glycan separation, and this has limited its application to analysis of complex glycan mixtures from biological samples. Further, permethylation can reduce liquid chromatographic (LC) resolution of isomeric glycans. Here, we studied the electronic excitation dissociation (EED) fragmentation behavior of native glycans with a reducing-end fixed charge tag and identified key spectral features that are useful for topology and linkage determination. We also developed a de novo glycan sequencing software that showed remarkable accuracy in glycan topology elucidation based on the EED spectra of fixed charge-derivatized glycans. The ability to obtain glycan structural details at the MS2 level, without permethylation, via a combination of fixed charge derivatization, EED, and de novo spectral interpretation, makes the present approach a promising tool for comprehensive and rapid characterization of glycan mixtures. PMID- 29443509 TI - pH-Responsive Microencapsulation Systems for the Oral Delivery of Polyanhydride Nanoparticles. AB - Multicompartmental polymer carriers, referred to as Polyanhydride-Releasing Oral MicroParticle Technology (PROMPT), were formed by a pH-triggered antisolvent precipitation technique. Polyanhydride nanoparticles were encapsulated into anionic pH-responsive microparticle gels, allowing for nanoparticle encapsulation in acidic conditions and subsequent release in neutral pH conditions. The effects of varying the nanoparticle composition and feed ratio on the encapsulation efficiency were evaluated. Nanoparticle encapsulation was confirmed by confocal microscopy and infrared spectroscopy. pH-triggered protein delivery from PROMPT was explored using ovalbumin (ova) as a model drug. PROMPT microgels released ova in a pH-controlled manner. Increasing the feed ratio of nanoparticles into the microgels increased the total amount of ova delivered, as well as decreased the observed burst release. The cytocompatibility of the polymer materials were assessed using cells representative of the GI tract. Overall, these results suggest that pH-dependent microencapsulation is a viable platform to achieve targeted intestinal delivery of polyanhydride nanoparticles and their payload(s).

AB - In the Li2O-Na2O-B2O3 system, LiNa4B15O25 has been successfully synthesized, which crystallizes in monoclinic space group C2 /c (No. 15), a = 14.153(3) A, b = 12.122(2) A, c = 12.719(2) A, beta = 105.237(13) degrees , and Z = 4. The isolated LiO5 polyhedra and the Na4O18 tetramers are located in the void space of the 3D infinity[B15O25] network of LiNa4B15O25. The symmetry of B15O30 is a new fundamental building block, which has never been reported before. Moreover, the whole framework can be defined as a new topology based on the TOPOS database. Interestingly, for the crystal structure LiB3O5, as 4/5 Li+ ions are substituted by the Na+ ions, a new compound LiNa4B15O25 has been successfully prepared. The structural comparison between the structures of LiB3O5 and LiNa4B15O25 and the changes caused by the cation substitution are discussed in this paper. PMID- 29443512 TI - Diels-Alder Click-Cross-Linked Hydrogels with Increased Reactivity Enable 3D Cell Encapsulation. AB - Engineered hydrogels have been extensively used to direct cell function in 3D cell culture models, which are more representative of the native cellular microenvironment than conventional 2D cell culture. Previously, hyaluronan-furan and bis-maleimide polyethylene glycol hydrogels were synthesized via Diels-Alder chemistry at acidic pH, which did not allow encapsulation of viable cells. In order to enable gelation at physiological pH, the reaction kinetics were accelerated by replacing the hyaluronan-furan with the more electron-rich hyaluronan-methylfuran. These new click-cross-linked hydrogels gel faster and at physiological pH, enabling encapsulation of viable cells, as demonstrated with 3D culture of 5 different cancer cell lines. The methylfuran accelerates Diels-Alder cycloaddition yet also increases the retro Diels-Alder reaction. Using computational analysis, we gain insight into the mechanism of the increased Diels Alder reactivity and uncover that transition state geometry and an unexpected hydrogen-bonding interaction are important contributors to the observed rate enhancement. This cross-linking strategy serves as a platform for bioconjugation and hydrogel synthesis for use in 3D cell culture and tissue engineering. PMID- 29443513 TI - Mass-Remainder Analysis (MARA): a New Data Mining Tool for Copolymer Characterization. AB - A new data mining method is proposed for the determination of the copolymer composition from moderate/low resolution complex mass spectra. The Mass-remainder analysis (MARA) does not require a "Kendrick-like" transformation to a new mass scale, it is simply based on the calculation of the remainder after dividing by the exact mass of one of the repeat units of the copolymer (e.g., B of an A/B copolymer). Plotting the remainder of this division (MR) versus m/ z the homologous series differing only by a number of base units (e.g., B unit) can be visualized. The number of A units ( nA) and subsequently nB is assigned to the m/ z peaks using the bijective nA, MR mapping. Simultaneously, our algorithm removes the isotopes from the peak list. However, the intensities of the monoisotopes are increased to the value corresponding, approximately, to the total intensity of their isotope peaks. The correction of the mass spectral peak intensities enables the accurate calculation of the usual polymer and copolymer quantities: the molecular weight-average, the number-averaged molecular weight of A and B units, the composition drift, or the bivariate distribution, among others. Our Mass remainder analysis method was demonstrated by the analysis of various ethylene oxide/propylene oxide copolymers. PMID- 29443514 TI - Environmentally Persistent Free Radicals: Insights on a New Class of Pollutants. AB - Environmentally persistent free radicals, EPFRs, exist in significant concentration in atmospheric particulate matter (PM). EPFRs are primarily emitted from combustion and thermal processing of organic materials, in which the organic combustion byproducts interact with transition metal-containing particles to form a free radical-particle pollutant. While the existence of persistent free radicals in combustion has been known for over half-a-century, only recently that their presence in environmental matrices and health effects have started significant research, but still in its infancy. Most of the experimental studies conducted to understand the origin and nature of EPFRs have focused primarily on nanoparticles that are supported on a larger micrometer-sized particle that mimics incidental nanoparticles formed during combustion. Less is known on the extent by which EPFRs may form on engineered nanomaterials (ENMs) during combustion or thermal treatment. In this critical and timely review, we summarize important findings on EPFRs and discuss their potential to form on pristine ENMs as a new research direction. ENMs may form EPFRs that may differ in type and concentration compared to nanoparticles that are supported on larger particles. The lack of basic data and fundamental knowledge about the interaction of combustion byproducts with ENMs under high-temperature and oxidative conditions present an unknown environmental and health burden. Studying the extent of ENMs on catalyzing EPFRs is important to address the hazards of atmospheric PM fully from these emerging environmental contaminants. PMID- 29443515 TI - Tuning Inner-Ear Tip-Link Affinity Through Alternatively Spliced Variants of Protocadherin-15. AB - Human hearing relies upon the tip-to-tip interaction of two nonclassical cadherins, protocadherin-15 (PCDH15) and cadherin-23 (CDH23). Together, these proteins form a filament called the tip link that connects neighboring stereocilia of mechanosensitive hair cells. As sound waves enter the cochlea, the stereocilia deflect and tension is applied to the tip link, opening nearby transduction channels. Disruption of the tip link by loud sound or calcium chelators eliminates transduction currents and illustrates that tip-link integrity is critical for mechanosensing. Tip-link remodeling after disruption is a dynamic process, which can lead to the formation of atypical complexes that incorporate alternatively spliced variants of PCDH15. These variants are categorized into six groups (N1-N6) based upon differences in the first two extracellular cadherin (EC) repeats. Here, we characterized the two N-terminal EC repeats of all PCDH15 variants (pcdh15(N1) to pcdh15(N6)) and combined these variants to test complex formation. We solved the crystal structure of a new complex composed of CDH23 EC1-2 (cdh23) and pcdh15(N2) at 2.3 A resolution and compared it to the canonical cdh23-pcdh15(N1) complex. While there were subtle structural differences, the binding affinity between cdh23 and pcdh15(N2) is ~6 times weaker than cdh23 and pcdh15(N1) as determined by surface plasmon resonance analysis. Steered molecular dynamics simulations predict that the unbinding force of the cdh23-pcdh15(N2) complex can be lower than the canonical tip link. Our results demonstrate that alternative heterophilic tip-link structures form stable protein-protein interactions in vitro and suggest that homophilic PCDH15-PCDH15 tip links form through the interaction of additional EC repeats. PMID- 29443516 TI - A Versatile and Robust Approach to Stimuli-Responsive Protein Multilayers with Biologically Enabled Unique Functions. AB - Protein-based materials call for innovative processing techniques to integrate their unique biologically enabled functions with other materials of complementary features. Herein, we report the covalent protein layer-by-layer assembly via orthogonal "Tag-Catcher" reactions as a facile and robust approach to make entirely protein-based multilayers on a variety of substrates. Programmed assembly of native telechelic proteins not only endows the materials valuable stimuli-sensitive behaviors, but also unique properties unparalleled by any synthetic counterparts. As proof of concept, super uranyl-binding protein (SUP) is immobilized on silica gel by this method with tunable capacity and enhanced capability for uranyl sequestration. Not only is the capturing performance enhanced in the multilayer setup, it also confers resilience to recycling, allowing efficient harvest of uranyl with an average of ~90% and ~60% recovery rate in over 10 cycles from water and synthetic seawater, respectively. The approach is the first entirely protein-based multilayers covalently assembled by the layer-by-layer method. It provides a platform for immobilizing proteins with synergistic enhancement of function and resilience and expands the scope and capability of genetically encoded protein-based materials. PMID- 29443517 TI - Lewis Acid Assisted Nitrate Reduction with Biomimetic Molybdenum Oxotransferase Complex. AB - The reduction of nitrate (NO3-) to nitrite (NO2-) is of significant biological and environmental importance. While MoIV(O) and MoVI(O)2 complexes that mimic the active site structure of nitrate reducing enzymes are prevalent, few of these model complexes can reduce nitrate to nitrite through oxygen atom transfer (OAT) chemistry. We present a novel strategy to induce nitrate reduction chemistry of a previously known catalyst MoIV(O)(SN)2 (2), where SN = bis(4- tert-butylphenyl)-2 pyridylmethanethiolate, that is otherwise incapable of achieving OAT with nitrate. Addition of nitrate with the Lewis acid Sc(OTf)3 (OTf = trifluoromethanesulfonate) to 2 results in an immediate and clean conversion of 2 to MoVI(O)2(SN)2 (1). The Lewis acid additive further reacts with the OAT product, nitrite, to form N2O and O2. This work highlights the ability of Sc3+ additives to expand the reactivity scope of an existing MoIV(O) complex together with which Sc3+ can convert nitrate to stable gaseous molecules. PMID- 29443518 TI - Highly Selective and Rapid Breath Isoprene Sensing Enabled by Activated Alumina Filter. AB - Isoprene is a versatile breath marker for noninvasive monitoring of high blood cholesterol levels as well as for influenza, end-stage renal disease, muscle activity, lung cancer, and liver disease with advanced fibrosis. Its selective detection in complex human breath by portable devices (e.g., metal-oxide gas sensors), however, is still challenging. Here, we present a new filter concept based on activated alumina powder enabling fast and highly selective detection of isoprene at the ppb level and high humidity. The filter contains high surface area adsorbents that retain hydrophilic compounds (e.g., ketones, alcohols, ammonia) representing major interferants in breath while hydrophobic isoprene is not affected. As a proof-of-concept, filters of commercial activated alumina powder are combined with highly sensitive but rather nonspecific, nanostructured Pt-doped SnO2 sensors. This results in fast (10 s) measurement of isoprene down to 5 ppb at 90% relative humidity with outstanding selectivity (>100) to breath relevant acetone, ammonia, ethanol, and methanol, superior to state-of-the-art isoprene sensors. Most importantly, when exposed continuously to simulated breath mixtures (four analytes) for 8 days, this filter-sensor system showed stable performance. It can be incorporated readily into a portable breath isoprene analyzer promising for simple-in-use monitoring of blood cholesterol or other patho/physiological conditions. PMID- 29443519 TI - Mercury Trithiolate Binding (HgS3) to a de Novo Designed Cyclic Decapeptide with Three Preoriented Cysteine Side Chains. AB - Mercury(II) is an unphysiological soft ion with high binding affinity for thiolate ligands. Its toxicity lies in the interactions with low molecular weight thiols including glutathione and cysteine-containing proteins that disrupt the thiol balance and alter vital functions. However, mercury can also be detoxified via interactions with Hg(II)-responsive regulatory proteins such as MerR, which coordinates Hg(II) with three cysteine residues in a trigonal planar fashion (HgS3 coordination). The model cyclodecapeptide P3C, c(GCTCSGCSRP) was designed to promote Hg(II) chelation in a HgS3 coordination environment through the parallel orientation of three cysteine side chains. The binding motif is derived from the dicysteine P2C cyclodecapeptide validated previously as a model for d10 metal transporters containing the binding sequence CxxC. The formation of the mononuclear HgP3C complex with a HgS3 coordination is demonstrated using electrospray ionization mass spectrometry, UV absorption, and 199Hg NMR. Hg LIII edge extended X-ray absorption fine structure (EXAFS) spectroscopy indicates that the Hg(II) coordination environment is T-shaped with two short Hg-S distances at 2.45 A and one longer distance at 2.60 A. The solution structure of the HgP3C complex was refined based on 1H-1H NMR constraints and EXAFS results. The cyclic peptide scaffold has a rectangular shape with the three binding cysteine side chains pointing toward Hg(II). The HgP3CH complex has a p Ka of 4.3, indicating that the HgS3 coordination mode is stable over a large range of pH. This low p Ka value suggests that the preorientation of the three cysteine groups is particularly well-achieved for Hg(II) trithiolate coordination in P3C. PMID- 29443520 TI - Cosolvent Effects on Polymer Hydration Drive Hydrophobic Collapse. AB - Water-mediated hydrophobic interactions play an important role in self-assembly processes, aqueous polymer solubility, and protein folding, to name a few. Cosolvents affect these interactions; however, the implications for hydrophobic polymer collapse and protein folding equilibria are not well-understood. This study examines cosolvent effects on the hydrophobic collapse equilibrium of a generic 32-mer hydrophobic polymer in urea, trimethylamine- N-oxide (TMAO), and acetone aqueous solutions using molecular dynamics simulations. Our results unveil a remarkable cosolvent-concentration-dependent behavior. Urea, TMAO, and acetone all shift the equilibrium toward collapsed structures below 2 M cosolvent concentration and, in turn, to unfolded structures at higher cosolvent concentrations, irrespective of the differences in cosolvent chemistry and the nature of cosolvent-water interactions. We find that weakly attractive polymer water van der Waals interactions oppose polymer collapse in pure water, corroborating related observations reviewed by Ben-Amotz ( Annu. Rev. Phys. Chem. 2016, 67, 617-638). The cosolvents studied in the present work adsorb at the polymer/water interface and expel water molecules into the bulk, thereby effectively removing the dehydration energy penalty that opposes polymer collapse in pure water. At low cosolvent concentrations, this leads to cosolvent-induced stabilization of collapsed polymer structures. Only at sufficiently high cosolvent concentrations, polymer-cosolvent interactions favor polymer unfolding. PMID- 29443521 TI - The Structure and Cl-O Dissociation Energy of the ClOO Radical: Finally, the Right Answers for the Right Reason. AB - The chlorine peroxy radical (ClOO) has historically been a highly problematic system for theoretical studies. In particular, the erratic ab initio predictions of the Cl-O bond length reported in the literature thus far exhibit unacceptable errors with respect to the experimental structure. In light of the widespread disagreement observed, we present a careful and systematic investigation of the ClOO geometry toward the basis set and correlation limits of single reference ab initio theory, employing the cc-pVXZ (X = D, T, Q, 5, 6) basis sets extrapolated to the complete basis set limit and coupled cluster theory through single, double, triple, and perturbative quadruple excitations [CCSDT(Q)]. We demonstrate a considerable sensitivity of the Cl-O bond length to both electron correlation and basis set size. The CCSDT(Q)/CBS structure is found to be re(ClO) = 2.082, re(OO) = 1.208, and thetae(ClOO) = 115.4 degrees , in remarkable agreement with Endo's semi-experimentally determined values re(ClO) = 2.084(1), re(OO) = 1.206(2), and thetae(ClOO) = 115.4(1) degrees . Moreover, we compute a Cl-O bond dissociation energy of 4.77 kcal mol-1, which is likewise in excellent agreement with the most recent experimental value of 4.69 +/- 0.10 kcal mol-1.

PMID- 29443523 TI - Simple Approach for the Rapid Detection of Alternariol in Pear Fruit by Surface Enhanced Raman Scattering with Pyridine-Modified Silver Nanoparticles. AB - A simple method based on surface-enhanced Raman scattering (SERS) was developed for the rapid determination of alternariol (AOH) in pear fruits using an easily prepared silver-nanoparticle (AgNP) substrate. The AgNP substrate was modified by pyridine to circumvent the weak affinity of the AOH molecules to the silver surface and to improve the sensitivity of detection. Quantitative analysis was performed in AOH solutions at concentrations ranging from 3.16 to 316.0 MUg/L, and the limit of detection was 1.30 MUg/L. The novel method was also applied to the detection of AOH residues in pear fruits purchased from the market and in pear fruits that were artificially inoculated with Alternaria alternata. AOH was not found in any of the fresh fruit, whereas it resided in the rotten and inoculated fruits. Finally, the SERS method was cross validated against HPLC. It was revealed that the SERS method has great potential utility in the rapid detection of AOH in pear fruits and other agricultural products. PMID- 29443524 TI - Encapsulation of Ionic Liquids with an Aprotic Heterocyclic Anion (AHA-IL) for CO2 Capture: Preserving the Favorable Thermodynamics and Enhancing the Kinetics of Absorption. AB - The performance of an ionic liquid with an aprotic heterocyclic anion (AHA-IL), trihexyl(tetradecyl)phosphonium 2-cyanopyrrolide ([P66614][2-CNPyr]), for CO2 capture has been evaluated considering both the thermodynamics and the kinetics of the phenomena. Absorption gravimetric measurements of the gas-liquid equilibrium isotherms of CO2-AHA-IL systems were carried out from 298 to 333 K and at pressures up to 15 bar, analyzing the role of both chemical and physical absorption phenomena in the overall CO2 solubility in the AHA-IL, as has been done previously. In addition, the kinetics of the CO2 chemical absorption process was evaluated by in situ Fourier transform infrared spectroscopy-attenuated total reflection, following the characteristic vibrational signals of the reactants and products over the reaction time. A chemical absorption model was used to describe the time-dependent concentration of species involved in the reactive absorption, obtaining kinetic parameters (such as chemical reaction kinetic constants and diffusion coefficients) as a function of temperatures and pressures. As expected, the results demonstrate that the CO2 absorption rate is mass-transfer-controlled because of the relatively high viscosity of AHA-IL. The AHA-IL was encapsulated in a porous carbon sphere (Encapsulated Ionic Liquid, ENIL) to improve the kinetic performance of the AHA-IL for CO2 capture. The newly synthesized AHA-ENIL material was evaluated as a CO2 sorbent with gravimetric absorption measurements. AHA-ENIL systems preserve the good CO2 absorption capacity of the AHA-IL but drastically enhance the CO2 absorption rate because of the increased gas-liquid surface contact area achieved by solvent encapsulation.

Although considerable progresses have been made in the calculation of potential energies in protein structure prediction, the computation for entropies of protein has lagged far behind, due to the challenge that estimation of entropies often requires expensive conformational sampling. In this study, we have used a knowledge-based approach to estimate the backbone conformational entropies from experimentally determined structures. Instead of conducting computationally expensive MD/MC simulations, we obtained the entropies of protein structures based on the normalized probability distributions of back dihedral angles observed in the native structures. Our new knowledge-based scoring function with inclusion of the backbone entropies, which is referred to as ITScoreDA or ITDA, was extensively evaluated on 16 commonly used decoy sets and compared with 50 other published scoring functions. It was shown that ITDA is significantly superior to the other tested scoring functions in selecting native structures from decoys. The present study suggests the role of backbone conformational entropies in protein structures and provides a way for fast estimation of the entropic effect.

AB - Overpopulation is already a reality, and the need for alternative technologies to meet a continuously increasing food demand has been much discussed around the world. In addition, soil decreasing fertility and desertification are obstacles that we will need to be overcome to increase crop productivity with a much reduced dependence upon inorganic fertilizers. In this context, protein hydrolysates has emerged as an important strategy to reduce the use of inorganic fertilizers, whose applications as biostimulants for plant growth have shown very promising results. PMID- 29443527 TI - Positron Scattering from Methyl Halides. AB - The well-known spherical complex optical potential (SCOP) and complex scattering potential-ionization contribution (CSP-ic) methods with appropriate modifications are applied to the CH3X (X = F, Cl, Br, and I) molecules to compute positron scattering cross sections, which rather is the first theoretical attempt to report the same. Besides, various inelastic cross sections are also predicted for the first time in this Article. We have utilized the multiscattering spherical complex optical potential (MSCOP) approach to derive these cross sections. In general, a reasonable accordance has been found between the present total cross sections and the experimental measurements. Apart from the inconsistency between the present theoretical and previous experimental cross sections in the low energy region, the present theory is found to produce consistent and reliable results at all other energies.

AB - This work presents scattering calculations for the O(3 P) + N2(1Sigma) -> NO(2Pi) + N(4S) and for the O(3 P) + HCl(1Sigma) -> OH(2Pi) + Cl(2P) reactions with a focus on the prediction of the Lambda-doublet populations in which NO and OH are produced. Both reactions can take place on two competing potential energy surfaces of symmetries 3 A' and 3 A" that correlate reagents with products but with very distinct topographies. As a result, they exhibit very different dynamical behaviors and total reactivity. Using a method that relates the reaction yield on the two competing surfaces to the Lambda-doublet populations through the explicit consideration of the stereodynamics of the reaction, we predict that the population of NO and OH on the two Lambda-doublet sates is surprisingly similar for both systems. These results contradict the model that assumes that collisions on the 3 A' and 3 A" would give rise to products in the Pi( A') and Pi( A") states, respectively. PMID- 29443529 TI - Amido Ca and Yb(II) Complexes Coordinated by Amidine-Amidopyridinate Ligands for Catalytic Intermolecular Olefin Hydrophosphination. AB - A series of amido Ca and Yb(II) complexes LM[N(SiMe3)2](THF) (1Yb, 1-4Ca) coordinated by amidine-amidopyridinate ligands L1-4 were synthesized via a transamination reaction between proligands L1-4H and bisamido complexes M[N(SiMe3)2]2(THF)2 (M = Yb, Ca). The reactions of Yb[N(SiMe3)2]2(THF)2 with proligands L2H-L4H containing CF3 and C6H4F fragments do not allow for preparing the target Yb(II) complexes, while the Ca analogues were synthesized in good yields. Complexes 1Yb and 1-4Ca were evaluated as precatalysts for hydrophosphination of styrene, p-substituted styrenes, alpha-Me-styrene, and 2,3 dimethylbutadiene with various primary and secondary phosphines (PhPH2, 2,4,6 Me3C6H2PH2, 2-C5NH4PH2, Ph2PH, Cy2PH). Complexes 1Yb, 1-4Ca performed high catalytic activities in styrene hydrophosphination with PhPH2 and Ph2PH and demonstrated high regioselectivity affording exclusively the anti-Markovnikov addition products. For primary PhPH2 the reactions (1:1 molar ratio of substrates) catalyzed by 1Yb, 1Ca, and 2Ca proved to be highly chemoselective affording the secondary phosphine Ph(PhCH2CH2)PH; however, complexes 3Ca and 4Ca led to the formation of both secondary and tertiary phosphines in 80:20 and 86:14 ratios. Styrene hydrophosphinations with 2,4,6-Me3C6H2PH2 and 2-pyridylphosphine for all complexes 1Yb and 1-4Ca proceeded much more slowly compared to PhPH2. Addition of 2-C5NH4PH2 to styrene catalyzed by complex 1Yb turned out to be non regioselective and led to the formation of a mixture of Markovnikov and anti Markovnikov addition products, while all Ca complexes enabled regioselective anti Markovnikov addition. Complexes 1Ca and 1Yb containing catalytic centers featuring similar ionic radii performed different catalytic activity: the ytterbium analogue proved to be a more active catalyst for intermolecular hydrophosphination of styrene with Cy2PH, 2-C5NH4PH2, and PhPH2, but less active with sterically demanding 2,4,6-Me3C6H2PH2. Styrenes containing in p-position electron-donating groups (Me, tBu, OMe) performed with noticeably lower rates in the reactions with PhPH2 compared to styrene. Complexes 1Yb, 1Ca, 2Ca, 3Ca, and 4Ca enabled addition of PhPH2 toward the double C?C bond of alpha-Me-styrene, and the reaction rate for this substrate is noticeably lower; however quantitative conversions were reached in ~40 h. Complexes 1Ca and 2Ca promoted 1,2-addition of PhPH2 to 2,3-dimethyl butadiene with excellent regio- and chemoselectivity to afford linear secondary phosphines. Hydrophosphination of inert 1-nonene with Ph2PH with 40% conversion becomes possible due to the application of complex 2Ca (40 h, 70 degrees C). The rate law for the hydrophosphination of styrene with Ph2PH catalyzed by 1Ca was found to agree with the idealized equation: v = k[styrene]1[1Ca]1. PMID- 29443530 TI - Competitive Multiple-Mechanism-Driven Electrochemiluminescent Detection of 8 Hydroxy-2'-deoxyguanosine. AB - Natural selection over billions of years has developed highly effective in vivo signal transduction that is often governed by a series of competitive multiple mechanisms. Several artificial signal transduction pathways have inspired numerous biosensing systems, but most of these are driven by a single mechanism. Herein we describe a multiple-mechanism-driven electrochemiluminescent (ECL) biosensor that utilizes competitive catalytic and steric hindrance effects by assembling hemin/G-quadruplex on carbon nitride nanosheets. Taking the detection of 8-hydroxy-2'-deoxyguanosine (8-OHdG) as example, the dynamic ranges of the detectable concentrations from the different mechanisms were integrated into a single sensor interface. Moreover, the detection sensitivity was more precisely controlled by the competition between the two mechanisms and inherently boosted compared with that of single-mechanism-driven detection. Going beyond the conventional single-mechanism-driven biosensing, the elaborate biomimetic coupling of multiple mechanisms in a single interface may open a new approach for future multiplexed biosensing. PMID- 29443531 TI - Application of Copper-Chitosan Nanoparticles Stimulate Growth and Induce Resistance in Finger Millet (Eleusine coracana Gaertn.) Plants against Blast Disease. AB - Copper-chitosan nanoparticle (CuChNp) was synthesized and used to study its effect on finger millet plant as a model plant system. Our objective was to explore the efficacy of CuChNp application to control blast disease of finger millet. CuChNp was applied to finger millet either as a foliar spray or as a combined application (involving seed coat and foliar spray). Both the application methods enhanced growth profile of finger millet plants and increased yield. The increased yield was nearly 89% in combined application method. Treated finger millet plants challenged with Pyricularia grisea showed suppression of blast disease development when compared to control. Nearly 75% protection was observed in the combined application of CuChNp to finger millet plants. In CuChNp treated finger millet plants, a significant increase in defense enzymes was observed, which was detected both qualitatively and quantitatively. The suppression of blast disease correlates well with increased defense enzymes in CuChNp treated finger millet plants. PMID- 29443532 TI - Aggregate Formation of Surface-Modified Nanoparticles in Solvents and Polymer Nanocomposites. AB - A new method based on the combination of small-angle scattering, reverse Monte Carlo simulations, and an aggregate recognition algorithm is proposed to characterize the structure of nanoparticle suspensions in solvents and polymer nanocomposites, allowing detailed studies of the impact of different nanoparticle surface modifications. Experimental small-angle scattering is reproduced using simulated annealing of configurations of polydisperse particles in a simulation box compatible with the lowest experimental q-vector. Then, properties of interest like aggregation states are extracted from these configurations and averaged. This approach has been applied to silane surface-modified silica nanoparticles with different grafting groups, in solvents and after casting into polymer matrices. It is shown that the chemistry of the silane function, in particular mono- or trifunctionality possibly related to patch formation, affects the dispersion state in a given medium, in spite of an unchanged alkyl-chain length. Our approach may be applied to study any dispersion or aggregation state of nanoparticles. Concerning nanocomposites, the method has potential impact on the design of new formulations allowing controlled tuning of nanoparticle dispersion. PMID- 29443533 TI - The Effects of a Yoga Exercise and Nutritional Guidance Program on Pregnancy Outcomes Among Healthy Pregnant Japanese Women: A Study Protocol for a Randomized Controlled Trial. AB - OBJECTIVES: This report provides an experimental protocol for a study designed to verify the effects of yoga exercise and a nutritional guidance program during pregnancy on several key pregnancy and birth outcomes among Japanese women. DESIGN: This is a study protocol of a randomized controlled trial. SETTING/LOCATION: This intervention will be carried out in a university hospital in Tokyo. SUBJECTS: Healthy primiparous women will be recruited at 18-23 gestational weeks in the hospital. A total of 400 participants will be randomly assigned to one of four groups in this trial, with 100 participants in each group group with yoga exercise, with nutritional guidance, with both yoga and nutritional guidance, and with standard care alone, as the control group. Yoga exercise consists of yoga classes held at the hospital 3 or 5 days a month, duration 60 min, and home practice using a digital video disk, duration 30 or 60 min per session. We recommend participants do yoga at least 3 days a week for a total of 60 min per day. Nutritional guidance is based on individual dietary intake assessed using a brief-type diet history questionnaire. RESULTS: The primary outcome is rate of pregnant women with adequate gestational weight gain. Secondary outcomes include physiologic and psychologic status assessed via biomarkers and health-related scales, dietary nutrition intake, and birth outcomes. CONCLUSIONS: This study shows the effects of a yoga exercise and nutritional intervention. If the intervention is found to be effective, our results will be useful for healthcare providers and pregnant women. PMID- 29443534 TI - Breastfeeding Is Primary.

PMID- 29443537 TI - A Randomized Clinical Trial to Evaluate Attached Hamstring Anterior Cruciate Ligament Graft Maturity With Magnetic Resonance Imaging. AB - BACKGROUND: The hamstring tendons are commonly harvested for anterior cruciate ligament (ACL) reconstruction with detachment of the tibial insertion. Retaining the insertion may help to preserve vascularity and viability of the graft and bypass the stages of avascular necrosis and revascularization, which might be beneficial to graft maturity. PURPOSE: To investigate and compare graft maturity by magnetic resonance imaging (MRI) after ACL reconstruction with preservation or detachment of hamstring tendon tibial insertion at up to 2 years. STUDY DESIGN: Randomized controlled trial; Level of evidence, 2. METHODS: Forty-five patients (age range, 18-45 years) undergoing isolated ACL reconstruction with hamstring tendon were enrolled and randomized to 2 groups. The tibial insertion of the hamstring tendon was preserved in the study group (n = 21) and detached in the control group (n = 24). Patients had follow-up at 3, 6, 12, and 24 months, which consisted of the following: (1) clinical examination and (2) MRI evaluation of graft signal intensity based on signal/noise quotient (SNQ) values. Finally, 18 patients in the study group and 19 in the control group received full follow-up evaluation (ie, at all 4 time points). RESULTS: All knees acquired full range of motion at 24 months without significant laxity. At each time point, the KT-1000 arthrometer revealed no significant difference between groups; the clinical scores significantly improved in both groups, although the difference between groups was not significant. In the control group, the SNQ value increased from 3 months, peaked at 6 months, and then decreased (3 months, 21.4 +/- 12.7; 6 months, 25.6 +/- 12; 12 months, 18.3 +/- 7.7; 24 months, 15.3 +/- 6.3). However, the insertion-preserved graft in the study group maintained relatively lower and unchanged signal intensity throughout all time points (3 months, 15.0 +/- 11.2; 6 months, 14.9 +/- 6.3; 12 months, 12.6 +/- 7.0; 24 months, 14.6 +/- 7.0). Between groups, there was no significant difference at 3 or 24 months ( P = .11 and .75, respectively), while the SNQ values were significantly lower in the study group versus the control group at 6 and 12 months ( P = .002 and .02, respectively). CONCLUSION: The insertion-detached hamstring tendon grafts underwent a significantly increasing change in signal intensity during the first 2 years after ACL reconstruction, while the insertion-preserved grafts kept a relatively lower and unchanged signal intensity. The difference was most significant at 6 and 12 months postoperatively. PMID- 29443538 TI - Arthroscopic Surgery or Physical Therapy for Patients With Femoroacetabular Impingement Syndrome: A Randomized Controlled Trial With 2-Year Follow-up. AB - BACKGROUND: Arthroscopic hip surgery has risen 18-fold in the past decade; however, there is a dearth of clinical trials comparing surgery with nonoperative management. PURPOSE: To determine the comparative effectiveness of surgery and physical therapy for femoroacetabular impingement syndrome. STUDY DESIGN: Randomized controlled trial; Level of evidence, 1. METHODS: Patients were recruited from a large military hospital after referral to the orthopaedic surgery clinic and were eligible for surgery. Of 104 eligible patients, 80 elected to participate, and the majority were active-duty service members (91.3%). No patients withdrew because of adverse events. The authors randomly selected patients to undergo either arthroscopic hip surgery (surgery group) or physical therapy (rehabilitation group). Patients in the rehabilitation group began a 12-session supervised clinic program within 3 weeks, and patients in the surgery group were scheduled for the next available surgery at a mean of 4 months after enrollment. Patient-reported outcomes of pain, disability, and perception of improvement over a 2-year period were collected. The primary outcome was the Hip Outcome Score (HOS; range, 0-100 [lower scores indicating greater disability]; 2 subscales: activities of daily living and sport). Secondary measures included the International Hip Outcome Tool (iHOT-33), Global Rating of Change (GRC), and return to work at 2 years. The primary analysis was on patients within their original randomization group. RESULTS: Statistically significant improvements were seen in both groups on the HOS and iHOT-33, but the mean difference was not significant between the groups at 2 years (HOS activities of daily living, 3.8 [95% CI, -6.0 to 13.6]; HOS sport, 1.8 [95% CI, -11.2 to 14.7]; iHOT-33, 6.3 [95% CI, -6.1 to 18.7]). The median GRC across all patients was that they "felt about the same" (GRC = 0). Two patients assigned to the surgery group did not undergo surgery, and 28 patients in the rehabilitation group ended up undergoing surgery. A sensitivity analysis of "actual surgery" to "no surgery" did not change the outcome. Twenty (33.3%) patients who underwent surgery and 4 (33.3%) who did not undergo surgery were medically separated from military service at 2 years. CONCLUSION: There was no significant difference between the groups at 2 years. Most patients perceived little to no change in status at 2 years, and one-third of military patients were not medically fit for duty at 2 years. Limitations include a single hospital, a single surgeon, and a high rate of crossover. Registration: NCT01993615 ( ClinicalTrials.gov identifier). PMID- 29443539 TI - Intermittent Exposure to Cigarette Smoke Increases Lung Tumors and the Severity of Emphysema More than Continuous Exposure. AB - Lung cancer and chronic obstructive pulmonary disease are leading causes of morbidity and mortality worldwide, and cigarette smoking is a main risk factor for both. The presence of emphysema, an irreversible lung disease, further raises the risk of lung cancer in patients with chronic obstructive pulmonary disease. The mechanisms involved in smoke-induced tumorigenesis and emphysema are not fully understood, attributable to a lack of appropriate animal models. Here, we optimized a model of cigarette smoke (CS)-induced lung cancer and emphysema in A/J mice treated with 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone, a potent carcinogen. We investigated whether variations in CS exposure patterns with the same total amount and duration of exposure affect tumorigenesis and/or development of emphysema. Continuous CS exposure for 3 months significantly suppressed 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone-induced development of adenomas and adenocarcinomas; however, emphysema independently developed during this period. Surprisingly, intermittent CS exposure increased the severity of emphysema and resulted in a higher incidence of adenocarcinomas. Furthermore, intermittent CS exposure elicited a marked increase in M2-polarized macrophages within and near the developed tumors. By employing a CS exposure protocol with repeated cycles of cessation and relapse, we provide evidence that intermittent CS exposure enhances tumorigenesis and emphysema progression more than that of continuous CS exposure.

AB - Peroxisomes are membrane-bound organelles that are best known for their roles in lipid metabolism. Mounting evidence indicates that they are also important nodes for antiviral signaling. While research over the past few decades has revealed effective viral strategies to block antiviral signalling pathways from the plasma membrane, mitochondria and/or the nucleus, until recently, very little was known about how viruses interfere with peroxisome-based antiviral signaling. In this essay, we review how viruses use a variety of strategies to interfere with peroxisome biogenesis, a phenomenon that has implications for evasion of the host immune system as well as pathogenesis. PMID- 29443541 TI - A Method for Choosing the Best Samples for Mars Sample Return. AB - Success of a future Mars Sample Return mission will depend on the correct choice of samples. Pyrolysis-FTIR can be employed as a triage instrument for Mars Sample Return. The technique can thermally dissociate minerals and organic matter for detection. Identification of certain mineral types can determine the habitability of the depositional environment, past or present, while detection of organic matter may suggest past or present habitation. In Mars' history, the Theiikian era represents an attractive target for life search missions and the acquisition of samples. The acidic and increasingly dry Theiikian may have been habitable and followed a lengthy neutral and wet period in Mars' history during which life could have originated and proliferated to achieve relatively abundant levels of biomass with a wide distribution. Moreover, the sulfate minerals produced in the Theiikian are also known to be good preservers of organic matter. We have used pyrolysis-FTIR and samples from a Mars analog ferrous acid stream with a thriving ecosystem to test the triage concept. Pyrolysis-FTIR identified those samples with the greatest probability of habitability and habitation. A three-tier scoring system was developed based on the detection of (i) organic signals, (ii) carbon dioxide and water, and (iii) sulfur dioxide. The presence of each component was given a score of A, B, or C depending on whether the substance had been detected, tentatively detected, or not detected, respectively. Single-step (for greatest possible sensitivity) or multistep (for more diagnostic data) pyrolysis-FTIR methods informed the assignments. The system allowed the highest priority samples to be categorized as AAA (or A*AA if the organic signal was complex), while the lowest-priority samples could be categorized as CCC. Our methods provide a mechanism with which to rank samples and identify those that should take the highest priority for return to Earth during a Mars Sample Return mission.

AB - Due to the high mortality of lung cancer, early diagnosis followed by early effective treatment is the key to prognosis improvement, which demands to identify the biological targets. Therefore, a multistage screening analysis was used to identify biological targets of lung adenocarcinoma. Two independent datasets of DNA methylation and RNA expression microarray in lung adenocarcinoma and normal lung tissues were chosen from the Gene Expression Omnibus. The association between DNA methylation and gene expression was explored, and the prognostic value of the hub genes was also evaluated. In this study, 8533 differential methylation sites, mostly located in the CpG island region and corresponding to 2754 genes (referred as differential methylation genes), were detected from methylation microarray. Besides, we obtained 830 differential expression genes, including 570 downregulated and 260 upregulated genes, through differential expression analysis. Protein-protein interaction analysis identified CXCL12, GFR, KDR, MMP9, TEK, and TWIST as core nodes, involving in the process of tumor cell identification, cell growth, cytokine secretion, inflammatory response, and angiogenesis. Among them, MMP9 and TWIST1 were identified as more valuable biological targets for the early diagnosis and targeted therapy of lung cancer through Kaplan-Meier analysis of TCGA lung adenocarcinoma datasets. Our study should contribute to the diagnosis and treatment of lung adenocarcinoma. PMID- 29443543 TI - ABCB1 1199G > A Polymorphism Impacts Transport Ability of P-gp-Mediated Antipsychotics. AB - The alterations in P-glycoprotein (P-gp)-mediated transport of antipsychotics due to the ABCB1 1199G>A polymorphism were assessed in the current study. The ABCB1wt and ABCB11199A recombinant cell models were constructed to study the sensitivity, intracellular accumulation, and transepithelial permeability of antipsychotic drugs. ABCB11199A recombinant cells had more sensitivity to olanzapine (2.2-fold, p < 0.01), aripiprazole (1.8-fold, p < 0.01), amisulpride (2.3-fold, p < 0.01), and risperidone (3.1-fold, p < 0.01) than ABCB1wt cells, while the resistance to paliperidone in both recombinant cell models was similar. In addition, the uptake quality of olanzapine, aripiprazole, amisulpride, and risperidone in ABCB11199A recombinant cells was greatly decreased compared to ABCB1wt cells (3.2-fold, p < 0.01; 3.7-fold, p < 0.01; 3.1-fold, p < 0.01; 2.6-fold, and p < 0.01, respectively). Furthermore, apparent permeability values were greatly increased in ABCB11199A recombinant cells compared with ABCB1wt recombinant cells for olanzapine (2.7-fold, p < 0.01), aripiprazole (2.9-fold, p < 0.01), amisulpride (3.4-fold, p < 0.01), and risperidone (4.1-fold, p < 0.01). The influence of ABCB1 1199G>A polymorphism on the transport of P-gp-mediated substrates showed up as drug-specific. Collectively, the ABCB1 1199G>A polymorphism may impact effective antipsychotics concentration in target cells via mediating the agents transport and distribution.

AB - The taste of l-glutamate and its synergism with 5'-ribonucleotides is thought to be primarily mediated through the T1R1+T1R3 heterodimer in some mammals, including rodents and humans. While knockout (KO) mice lacking either receptor subunit show impaired sensitivity to a range of monosodium glutamate (MSG) concentrations mixed with 2.5 mM inosine 5'-monophosphate (IMP) in amiloride, wild-type (WT) controls can detect this IMP concentration, hindering direct comparison between genotypes. Moreover, some residual sensitivity persists in the KO group, suggesting that the remaining subunit could maintain a limited degree of function. Here, C57BL/6J, 129X1/SvJ, and T1R1+T1R3 double KO mice ( n = 16 each to start the experiment) were trained in a two-response operant task in gustometers and then tested for their ability to discriminate 100 uM amiloride from MSG (starting with 0.6 M) and IMP (starting with 2.5 mM) in amiloride (MSG+I+A). Testing continued with successive dilutions of both MSG and IMP (in amiloride). The two WT strains were similarly sensitive to MSG+I+A ( P > 0.8). KO mice, however, were significantly impaired relative to either WT strain ( P < 0.01), although they were able to detect the highest concentrations. Thus, normal detectability of MSG+I+A requires an intact T1R1+T1R3 receptor, without regard for allelic variation in the T1R3 gene between the WT strains. Nevertheless, residual sensitivity by the T1R1+T1R3 KO mice demonstrates that a T1R-independent mechanism can contribute to the detectability of high concentrations of this prototypical umami compound stimulus. PMID- 29443546 TI - Akt1 deficiency diminishes skeletal muscle hypertrophy by reducing satellite cell proliferation. AB - Skeletal muscle mass is determined by the net dynamic balance between protein synthesis and degradation. Although the Akt/mechanistic target of rapamycin (mTOR)-dependent pathway plays an important role in promoting protein synthesis and subsequent skeletal muscle hypertrophy, the precise molecular regulation of mTOR activity by the upstream protein kinase Akt is largely unknown. In addition, the activation of satellite cells has been indicated as a key regulator of muscle mass. However, the requirement of satellite cells for load-induced skeletal muscle hypertrophy is still under intense debate. In this study, female germline Akt1 knockout (KO) mice were used to examine whether Akt1 deficiency attenuates load-induced skeletal muscle hypertrophy through suppressing mTOR-dependent signaling and satellite cell proliferation. Akt1 KO mice showed a blunted hypertrophic response of skeletal muscle, with a diminished rate of satellite cell proliferation following mechanical overload. In contrast, Akt1 deficiency did not affect the load-induced activation of mTOR signaling and the subsequent enhanced rate of protein synthesis in skeletal muscle. These observations suggest that the load-induced activation of mTOR signaling occurs independently of Akt1 regulation and that Akt1 plays a critical role in regulating satellite cell proliferation during load-induced muscle hypertrophy. PMID- 29443545 TI - Ovine uteroplacental and fetal metabolism during and after fetal cortisol overexposure in late gestation. AB - Cortisol modifies fetal metabolism in preparation for delivery, but whether preterm cortisol exposure programs persisting changes in fetoplacental metabolism remains unknown. This study infused fetal sheep with saline ( n = 36) or cortisol ( n = 27) to raise fetal plasma cortisol to normal prepartum concentrations for 5 days from day 125 of gestation (term: ~145 days). Fetal uptake and uteroplacental metabolism of glucose, oxygen, and lactate, together with fetal hepatic glucogenic capacity, were measured on the final day of infusion or 5 days later. Cortisol reduced adrenal weight and umbilical glucose uptake during infusion but increased fetal glucose concentrations, hepatic glycogen content, and hepatic glucogenic enzyme activity (fructose-1,6-bisphosphatase and glucose-6 phosphatase) and gene expression ( PC and G6PC) compared with saline infusion. Postcortisol infusion, umbilical glucose uptake, and hepatic glucose-6 phosphatase activity remained low and high, respectively, whereas fetal glucose levels normalized and hepatic glycogen was lower with higher adrenal weights than in controls. Cortisol infusion increased the proportion of total uterine glucose uptake consumed by the uteroplacental tissues, irrespective of age. Placental tracer glucose transport capacity was also increased after, but not during, cortisol infusion, without changes in placental glucose transporter gene expression. Blood lactate concentration and Pco2 were higher, whereas pH and O2 content were lower in cortisol-infused than saline-infused fetuses, although uteroplacental metabolism and fetal uptake of oxygen and lactate were unaltered. The results suggest that preterm cortisol overexposure alters fetoplacental metabolism and adrenal function subsequently with persisting increases in uteroplacental glucose consumption at the expense of the fetal supply. PMID- 29443547 TI - Modeling heart failure risk in diabetes and kidney disease: limitations and potential applications of transverse aortic constriction in high-fat-fed mice. AB - There is an increased incidence of heart failure in individuals with diabetes mellitus (DM). The coexistence of kidney disease in DM exacerbates the cardiovascular prognosis. Researchers have attempted to combine the critical features of heart failure, using transverse aortic constriction, with DM in mice, but variable findings have been reported. Furthermore, kidney outcomes have not been assessed in this setting; thus its utility as a model of heart failure in DM and kidney disease is unknown. We generated a mouse model of obesity, hyperglycemia, and mild kidney pathology by feeding male C57BL/6J mice a high-fat diet (HFD). Cardiac pressure overload was surgically induced using transverse aortic constriction (TAC). Normal diet (ND) and sham controls were included. Heart failure risk factors were evident at 8-wk post-TAC, including increased left ventricular mass (+49% in ND and +35% in HFD), cardiomyocyte hypertrophy (+40% in ND and +28% in HFD), and interstitial and perivascular fibrosis (Masson's trichrome and picrosirius red positivity). High-fat feeding did not exacerbate the TAC-induced cardiac outcomes. At 11 wk post-TAC in a separate mouse cohort, echocardiography revealed reduced left ventricular size and increased left ventricular wall thickness, the latter being evident in ND mice only. Systolic function was preserved in the TAC mice and was similar between ND and HFD. Thus combined high-fat feeding and TAC in mice did not model the increased incidence of heart failure in DM patients. This model, however, may mimic the better cardiovascular prognosis seen in overweight and obese heart failure patients. PMID- 29443548 TI - Sex- and bone-specific responses in bone structure to exogenous leptin and leptin receptor antagonism in the ovine fetus. AB - Widespread expression of leptin and its receptor in developing cartilage and bone suggests that leptin may regulate bone growth and development in the fetus. Using microcomputed tomography, this study investigated the effects of exogenous leptin and leptin receptor antagonism on aspects of bone structure in the sheep fetus during late gestation. From 125 to 130 days of gestation (term ~145 days), chronically catheterized singleton sheep fetuses were infused intravenously for 5 days with either saline (0.9% saline, n = 13), recombinant ovine leptin at two doses (0.6 mg.kg-1.day-1 LEP1, n = 10 or 1.4 mg.kg-1.day-1 LEP2, n = 7), or recombinant superactive ovine leptin receptor antagonist (4.6 mg.kg-1.day-1 SOLA, n = 6). No significant differences in plasma insulin-like growth factor-I, osteocalcin, calcium, inorganic phosphate, or alkaline phosphatase were observed between treatment groups. Total femur midshaft diameter and metatarsal lumen diameter were narrower in male fetuses treated with exogenous leptin. In a fixed length of femur midshaft, total and bone volumes were reduced by the higher dose of leptin; nonbone space volume was lower in both groups of leptin-treated fetuses. Leptin infusion caused increments in femur porosity and connectivity density, and vertebral trabecular thickness. Leptin receptor antagonism decreased trabecular spacing and increased trabecular number, degree of anisotrophy, and connectivity density in the lumbar vertebrae. The increase in vertebral porosity observed following leptin receptor antagonism was greater in the malecompared with female, fetuses. Therefore, leptin may have a role in the growth and development of the fetal skeleton, dependent on the concentration of leptin, sex of the fetus, and bone type examined.

AB - Insulin resistance of peripheral muscle is implicated in the etiology of metabolic syndrome in obesity. Although accumulation of glycerolipids, such as triacylglycerol and diacylglycerol (DAG), in muscle contributes to insulin resistance in obese individuals, endurance-trained athletes also have higher glycerolipid levels but normal insulin sensitivity. We hypothesized that the difference in insulin sensitivity of skeletal muscle between athletes and obese individuals stems from changes in fatty acid composition of accumulated lipids. Here, we evaluated the effects of intense endurance exercise and high-fat diet (HFD) on the accumulation and composition of lipid molecular species in rat skeletal muscle using a lipidomic approach. Sprague-Dawley female rats were randomly assigned to three groups and received either normal diet (ND) in sedentary conditions, ND plus endurance exercise training, or HFD in sedentary conditions. Rats were fed ND or HFD between 4 and 12 wk of age. Rats in the exercise group ran on a treadmill for 120 min/day, 5 days/wk, for 8 wk. Soleus muscle lipidomic profiles were obtained using liquid chromatography/tandem mass spectrometry. Total DAG levels, particularly those of palmitoleate-containing species, were increased in muscle by exercise training. However, whereas the total DAG level in the muscle was also increased by HFD, the levels of DAG molecular species containing palmitoleate were decreased by HFD. The concentration of phosphatidylethanolamine molecular species containing palmitoleate was increased by exercise but decreased by HFD. Our results indicate that although DAG accumulation was similar levels in trained and sedentary obese rats, specific changes in molecular species containing palmitoleate were opposite. PMID- 29443550 TI - Erythropoietin, a putative neurotransmitter during hypoxia, is produced in RVLM neurons and activates them in neonatal Wistar rats. AB - Recent studies indicate that erythropoietin (EPO) is present in many areas of the brain and is active in the restoration of impaired neurons. In this study, we examined the presence of EPO and its role in bulbospinal neurons in the rostral ventrolateral medulla (RVLM). Hypoxia is often accompanied by a high blood pressure (BP). We hypothesized that EPO is produced in response to hypoxia in RVLM neurons and then activates them. To investigate whether RVLM neurons are sensitive to EPO, we examined the changes in the membrane potentials (MPs) of bulbospinal RVLM neurons using the whole cell patch-clamp technique during superfusion with EPO. A brainstem-spinal cord preparation was used for the experiments. EPO depolarized the RVLM neurons, and soluble erythropoietin receptor (SEPOR), an antagonist of EPO, hyperpolarized them. Furthermore, hypoxia depolarized RVLM neurons were significantly hyperpolarized by SEPOR. In histological examinations, the EPO-depolarized RVLM neurons showed the presence of EPO receptor (EPOR). The RVLM neurons that possessed EPORs showed the presence of EPO and hypoxia-inducible factor (HIF)-2alpha. We also examined the levels of HIF-2alpha and EPO messenger RNA (mRNA) in the ventral sites of the medullas (containing RVLM areas) in response to hypoxia. The levels of HIF-2alpha and EPO mRNA in the hypoxia group were significantly greater than those in the control group. These results suggest that EPO is produced in response to hypoxia in RVLM neurons and causes a high BP via the stimulation of those neurons. EPO may be one of the neurotransmitters produced by RVLM neurons during hypoxia. PMID- 29443551 TI - Role of respiration in the cardiovascular response to orthostatic and mental stress. AB - The objective of this study was to determine the response of heart rate and blood pressure variability (respiratory sinus arrhythmia, baroreflex sensitivity) to orthostatic and mental stress, focusing on causality and the mediating effect of respiration. Seventy-seven healthy young volunteers (46 women, 31 men) aged 18.4 +/- 2.7 yr underwent an experimental protocol comprising supine rest, 45 degrees head-up tilt, recovery, and a mental arithmetic task. Heart rate variability and blood pressure variability were analyzed in the time and frequency domain and modeled as a multivariate autoregressive process where the respiratory volume signal acted as an external driver. During head-up tilt, tidal volume increased while respiratory rate decreased. During mental stress, breathing rate increased and tidal volume was elevated slightly. Respiratory sinus arrhythmia decreased during both interventions. Baroreflex function was preserved during orthostasis but was decreased during mental stress. While sex differences were not observed during baseline conditions, cardiovascular response to orthostatic stress and respiratory response to mental stress was more prominent in men compared with women. The respiratory response to the mental arithmetic tasks was more prominent in men despite a significantly higher subjectively perceived stress level in women. In conclusion, respiration shows a distinct response to orthostatic versus mental stress, mediating cardiovascular variability; it needs to be considered for correct interpretation of heart rate and blood pressure phenomena. PMID- 29443552 TI - Alamandine acts via MrgD to induce AMPK/NO activation against ANG II hypertrophy in cardiomyocytes. AB - The renin-angiotensin system (RAS) plays a pivotal role in the pathogenesis of cardiovascular diseases. New members of this system have been characterized and shown to have biologically relevant actions. Alamandine and its receptor MrgD are recently identified components of RAS. In the cardiovascular system, alamandine actions included vasodilation, antihypertensive, and antifibrosis effects. Currently, the actions of alamandine on cardiomyocytes are unknown. Here our goal was twofold: 1) to unravel the signaling molecules activated by the alamandine/MrgD axis in cardiomyocytes; and 2) to evaluate the ability of this axis to prevent angiotensin II (ANG II)-induced hypertrophy. In cardiomyocytes from C57BL/6 mice, alamandine treatment induced an increase in nitric oxide (NO) production, which was blocked by d-Pro7-ANG-(1-7), a MrgD antagonist. This NO rise correlated with increased phosphorylation of AMPK. Alamandine-induced NO production was preserved in Mas-/- myocytes and lost in MrgD-/- cells. Binding of fluorescent-labeled alamandine was observed in wild-type cells, but it was dramatically reduced in MrgD-/- myocytes. We also assessed the consequences of prolonged alamandine exposure to cultured neonatal rat cardiomyocytes (NRCMs) treated with ANG II. Treatment of NRCMs with alamandine prevented ANG II-induced hypertrophy. Moreover, the antihypertrophic actions of alamandine were mediated via MrgD and NO, since they could be prevented by d-Pro7-ANG-(1-7) or inhibitors of NO synthase or AMPK. beta-Alanine, a MrgD agonist, recapitulated alamandine's cardioprotective effects in cardiomyocytes. Our data show that alamandine via MrgD induces AMPK/NO signaling to counterregulate ANG II-induced hypertrophy. These findings highlight the therapeutic potential of the alamandine/MrgD axis in the heart. PMID- 29443553 TI - Highly conserved motifs within the large Sec7 ARF guanine nucleotide exchange factor GBF1 target it to the Golgi and are critical for GBF1 activity. AB - Cellular life requires the activation of the ADP-ribosylation factors (ARFs) by Golgi brefeldin A-resistant factor 1 (GBF1), a guanine nucleotide exchange factor (GEF) with a highly conserved catalytic Sec7 domain (Sec7d). In addition to the Sec7d, GBF1 contains other conserved domains whose functions remain unclear. Here, we focus on HDS2 (homology downstream of Sec7d 2) domain because the L1246R substitution within the HDS2 alpha-helix 5 of the zebrafish GBF1 ortholog causes vascular hemorrhaging and embryonic lethality (13). To dissect the structure/function relationships within HDS2, we generated six variants, in which the most conserved residues within alpha-helices 1, 2, 4, and 6 were mutated to alanines. Each HDS2 mutant was assessed in a cell-based "replacement" assay for its ability to support cellular functions normally supported by GBF1, such as maintaining Golgi homeostasis, facilitating COPI recruitment, supporting secretion, and sustaining cellular viability. We show that cells treated with the pharmacological GBF1 inhibitor brefeldin A (BFA) and expressing a BFA-resistant GBF1 variant with alanine substitutions of RDR1168 or LF1266 are compromised in Golgi homeostasis, impaired in ARF activation, unable to sustain secretion, and defective in maintaining cellular viability. To gain insight into the molecular mechanism of this dysfunction, we assessed the ability of each GBF1 mutant to target to Golgi membranes and found that mutations in RDR1168 and LF1266 significantly decrease targeting efficiency. Thus, these residues within alpha helix 2 and alpha-helix 6 of the HDS2 domain in GBF1 are novel regulatory determinants that support GBF1 cellular function by impacting the Golgi-specific membrane association of GBF1.

AB - OBJECTIVES: To determine if the Power Through Choices (PTC) intervention can increase the use of birth control and reduce pregnancy among system-involved youths living in group care homes. METHODS: We performed a 2-arm cluster randomized controlled trial involving group care homes operated by child welfare or juvenile justice systems in California, Maryland, and Oklahoma with assessments immediately before and after the intervention, and at 6- and 12-month follow-up. We collected data from 2012 to 2014 via self-administered questionnaires. Participants (n = 1036) were young (mean age = 16.1 years), predominantly male (79%), racially/ethnically diverse (37% Hispanic, 20% Black, 21% White, 17% multiracial), and sexually experienced (88%). RESULTS: At 6-month follow-up, participants in the intervention group had significantly lower odds of having recent sexual intercourse without using birth control (adjusted odds ratio [AOR] = 0.72; 95% confidence interval [CI] = 0.52, 0.98). At 12-month follow-up assessment, participants in the intervention group had significantly lower odds of ever being pregnant or getting someone pregnant (AOR = 0.67; 95% CI = 0.46, 0.99). CONCLUSIONS: The results suggest that PTC is an effective sexual health education intervention that can be implemented with system-involved youths who represent a sexually experienced multiracial youth population.

PMID- 29443561 TI - Building Bridges to a Brighter Tomorrow: A Systematic Evidence Review of Interventions That Prepare Adolescents for Adulthood. AB - BACKGROUND: Data suggest that adverse social determinants during adolescence can set in motion a lifetime of poor social and health outcomes. Vulnerable youths are at particularly high risk in this regard. OBJECTIVES: To identify and assess the current evidence base for adolescent-focused interventions designed to influence adulthood preparation that could affect longer-term social determinants. SEARCH METHODS: Using a systematic review methodology, we conducted an initial assessment of intervention evaluations targeting 6 adulthood preparation subject (APS) areas to assess the quality and character of the evidence base. The review is specific to evaluated interventions that address at least 1 of the 6 APS areas: healthy relationships, adolescent development, financial literacy, parent-child communication, educational and career success, and healthy life skills. SELECTION CRITERIA: The inclusion criteria were as follows: (1) published in English in an independent, peer-reviewed journal; (2) conducted in developed, English-speaking countries; (3) implemented an intervention that addressed at least 1 of the 6 APS areas, delivered in an in person setting; (4) included youths at the 5th- through 12th-grade levels or aged 10 to 18 years at some point during intervention implementation; (5) included an evaluation component with a comparison group and baseline and follow-up measures; (6) included behavioral measures as outcomes; and (7) reported statistical significance levels for the behavioral outcome measures. DATA COLLECTION AND ANALYSIS: We developed an abstraction form to capture details from each article, including key details of the intervention, such as services, implementer characteristics, and timing; adulthood preparation foci; evaluation design, methods, and key behavioral measures; and results, including key statistically significant results for behavior-based outcome measures. We assessed study quality by using several key factors, including randomization, baseline equivalence of treatment and control groups, attrition, and confounding factors. We characterized the quality of evidence as high, moderate, or low on the basis of the described design and execution of the research. Our assessment included only information stated explicitly in the manuscript. MAIN RESULTS: A total of 36 independent intervention evaluations met the criteria for inclusion. Of these, 27 (75%) included significant findings for behavioral outcomes related to adulthood preparation. Quality was mixed across studies. Of the 36 studies reviewed, 27 used a randomized controlled design (15 group randomization, 12 individual randomization), whereas the others used observational pre-post designs. Ten studies used mixed-methods approaches. Most (n = 32) studies used self-report questionnaires at baseline with a follow-up questionnaire, and 14 studies included multiple follow-up points. Of the studies reviewed, 7 studies received a high-quality rating, indicating no significant issues identified within our quality criteria. We rated 23 studies as moderate quality, indicating methodological challenges within 1 of the quality criteria categories. The most common reasons studies were down-rated were poor baseline equivalency across treatment groups (or no discussion of baseline equivalency) and high levels of attrition. Finally, 6 studies received a low-quality rating because of methodological challenges across multiple quality domains. The studies broadly represented the APS areas. We identified no systematic differences in study quality across the APS areas. AUTHOR'S CONCLUSIONS: Although some of the intervention results indicate behavioral changes that may be linked to adulthood preparation skills, many of the extant findings are derived from moderate- or poor-quality studies. Additional work is needed to build the evidence base by using methodologically rigorous implementation and evaluation designs and execution. Public Health Implications. Interventions designed to help adolescents better prepare for adulthood may have the potential to affect their longer-term social determinants of health and well-being. More theory-driven approaches and rigorously evaluated interventions could strengthen the evidence base and improve the effectiveness of these adulthood preparation interventions.

AB - OBJECTIVES: To explore the programmatic reach and experience of high-need adolescents who received sexual health education in 3 distinct implementation settings (targeted-prevention settings, traditional schools, and alternative schools) through a statewide sexual health education program. METHODS: Data are from youth surveys collected between September 2013 and December 2014 in the California Personal Responsibility Education Program. A sample of high-need participants (n = 747) provided data to examine the impact of implementation setting on reach and program experience. RESULTS: Implementation in targeted prevention settings was equal to or more effective at providing a positive program experience for high-need participants. More than 5 times as many high need participants were served in targeted-prevention settings compared with traditional schools. Reaching the same number of high-need participants served in targeted-prevention settings over 15 months would take nearly 7 years of programming in traditional schools. CONCLUSIONS: To maximize the reach and experience of high-need youth populations receiving sexual health education, state and local agencies should consider the importance of implementation setting. Targeted resources and efforts should be directed toward high-need young people by expanding beyond traditional school settings. PMID- 29443581 TI - Erratum.

AB - Over the course of the past century, the challenges facing the United States in its consumption of health care goods and services have not changed very much. What is being consumed, who is paying for it, and how much is affordable are questions that arise in every cycle of the debate-if they ever go dormant. National Health Accounts are one tool to use in the search for answers to these questions and to the challenges behind the questions. The accounts cannot (and do not pretend to) address every aspect of the debate, but they provide an important context. In this article I briefly review the history of the health accounts and discuss their strengths and weaknesses in the context of the present debate over spending. PMID- 29443597 TI - What Is The US Health Spending Problem? AB - Is increased spending on medical care harmful to the US economy? The overall share of the gross domestic product spent on medical care is not a problem, provided that the services bought are worth more than their cost. However, high and rising costs expose two often-overlooked problems. First, spending is too high because many dollars are wasted. Estimates suggest that unnecessary medical spending costs the typical American family thousands of dollars each year. Second, high medical costs combined with stagnant incomes for a large share of the population and the inability of governments at all levels to raise tax dollars leads to increased health and economic disparities: fewer people covered by private insurance, the rationing of care in public health programs, and the lack of funds for other social programs. These distribution issues, coupled with the large waste, imply that efforts to address medical spending need to be among our highest priorities. PMID- 29443598 TI - Evaluation of Natural Product Compositions for Appetite Suppression. AB - A change in homeostasis between food intake and energy expenditure is the hallmark of obesity. Many plant-based weight-management products are available in dietary supplement markets with no direct efficacy comparison. In this in vivo acute feed intake study in rats, the appetite suppression efficacy of well-known natural ingredients in the weight-loss market were evaluated. We tested pure caffeine, potato skin extract, Cissus quadrangularis extract, Garcinia cambogia extract, Crocus sativus extract, raspberry ketone isolated from Rubus idaeus, one commercial product (Appetrex), and one novel composition (UP601). Rats treated with potato skin extract, Crocus sativus bulb extract, and Cissus quadrangularis extracts showed statistically significant reduction in food consumption only at the 2-hour timepoint with 44.9%, 34.1%, and 44.3% reductions, respectively, after food provision at an equivalent human dosage of 2 g, 10 g, and 10 g, respectively. Garcinia cambogia fruit extract and raspberry ketone from Rubus idaeus showed statistically significant reduction in food consumption only at the 1-hour timepoint with 33.7% and 79.4% reductions, respectively, after food provision at an equivalent human dosage of 8 g and 5 g, respectively. UP601 and Appetrex were compared at 230 mg/kg. While 88.5%, 73.8%, and 63.1% reductions in food intake were observed for the UP601 treatment group, 64.2%, 27.5%, and 34.7% reductions in food intake were observed for rats treated with Appetrex at 1 h, 2 h, and 4 h after food provision. The composition UP601 demonstrated superior activity in food intake compared to any of the dietary supplements marketed for appetite suppression tested in this study.

Elevated vasodilatory cyclases and shorter telomere length contribute to high-altitude pulmonary edema. High Alt Med Biol. 19:60-68, 2018. AIM: High-altitude (HA) genetics is complex with respect to health and disease (HA pulmonary edema i.e., HAPE). Based on the widely recognized fact that oxidative stress is a major trigger of several physiological processes, this study was designed to establish the significance of vasodilatory cyclases and telomere length in HA physiology. The study was performed in three groups, namely HAPE-free sojourners (HAPE-f, n = 150), HAPE patients (HAPE-p, n = 150), and healthy highland natives or highlanders (HLs, n = 150). Variations in soluble guanylyl cyclase beta1-subunit (GUCY1B3) and adenylyl cyclase type 6 (ADCY6) were genotyped by the SNaPshot method and/or Fluidigm SNP type genotyping. Plasma GUCY1B3 and ADCY6 levels were estimated using ELISA, and relative telomere length was estimated by qRT-PCR. RESULTS: The rs7638AA genotype was over-represented in HLs compared with HAPE-f and HAPE-p (p = 0.035 and p = 0.012, respectively). Similarly, the rs7638A allele was prevalent in HLs compared with both groups, but significance was attained against HAPE-p (p = 0.012). Significantly elevated plasma levels of GUCY1B3 and ADCY6 were obtained in HAPE-p compared with HAPE-f (p = 0.001 and p = 0.006, respectively) and HLs (p = 3.31E-05 and p = 0.05, respectively). Shorter telomere length was observed in HAPE-p compared with HAPE f (p > 0.05) and HLs (p = 0.017). CONCLUSION: Elevated cyclases and shorter telomere length associate with HAPE pathophysiology.

AB - The term patient noncompliance emerged in the 1970s as a tool for analyzing why people do not follow medical directives. Despite its early popularity, the term has languished in sociology while flourishing in biomedical arenas. It seems flaccid in a contemporary healthcare context as it overestimates physician authority and is tone-deaf to biomedicalization. I draw from sociological and anthropological traditions, as well as qualitative interviews with terminally ill patients ( N = 26) and their caregivers ( N = 16), to consider facets of a biomedicalized health experience and implications for an updated vision of compliance. First, pathways to care have proliferated under biomedicalization. With increased pathways comes increased need for understanding how treatment plans are socially constituted and assessed. Finally, increased complexity demands a more diverse vocabulary for understanding health related decisions. This paper is a call to sociologists to take the lead in transforming and updating this consequential concept. PMID- 29443626 TI - Immunogenicity of Fractional-Dose Vaccine during a Yellow Fever Outbreak - Preliminary Report. AB - Background In 2016, the response to a yellow fever outbreak in Angola and the Democratic Republic of Congo led to a global shortage of yellow fever vaccine. As a result, a fractional dose of the 17DD yellow fever vaccine (containing one fifth [0.1 ml] of the standard dose) was offered to 7.6 million children 2 years of age or older and nonpregnant adults in a preemptive campaign in Kinshasa. The goal of this study was to assess the immune response to the fractional dose in a large-scale campaign. Methods We recruited participants in four age strata at six vaccination sites. We assessed neutralizing antibody titers against yellow fever virus in blood samples obtained before vaccination and 28 to 35 days after vaccination, using a plaque reduction neutralization test with a 50% cutoff (PRNT50). Participants with a PRNT50 titer of 10 or higher at baseline were considered to be seropositive. Those with a baseline titer of less than 10 who became seropositive at follow-up were classified as having undergone seroconversion. Participants who were seropositive at baseline and who had an increase in the titer by a factor of 4 or more at follow-up were classified as having an immune response. Results Among 716 participants who completed follow up, 705 (98%; 95% confidence interval [CI], 97 to 99) were seropositive after vaccination. Among 493 participants who were seronegative at baseline, 482 (98%; 95% CI, 96 to 99) underwent seroconversion. Among 223 participants who were seropositive at baseline, 148 (66%; 95% CI, 60 to 72) had an immune response. Lower baseline titers were associated with a higher probability of having an immune response (P<0.001). Conclusions A fractional dose of the 17DD yellow fever vaccine was effective at inducing seroconversion in most of the participants who were seronegative at baseline. These findings support the use of fractional-dose vaccination for outbreak control. (Funded by the U.S. Agency for International Development and the Centers for Disease Control and Prevention.).

AB - Calprotectin (S100A8/A9), a heterodimeric complex of calcium-binding proteins S100A8 and S100A9, is encoded by genes mapping to the chromosomal locus 1q21.3 of the epidermal differentiation complex. Whereas extracellular calprotectin shows proinflammatory and antimicrobial properties by signaling through RAGE and TLR4, intracytoplasmic S100A8/A9 appears to be important for cellular development, maintenance, and survival. S100A8/A9 is constitutively expressed in myeloid cells and the stratified mucosal epithelia lining the oropharyngeal and genitourinary mucosae. While upregulated in adenocarcinomas and other cancers, calprotectin mRNA and protein levels decline in head and neck squamous cell carcinoma (HNSCC). S100A8/A9 is also lost during head and neck preneoplasia (dysplasia). Calprotectin decrease does not correlate with the clinical stage (TNM) of HNSCC. When expressed in carcinoma cells, S100A8/A9 downregulates matrix metalloproteinase 2 expression and inhibits invasion and migration in vitro. S100A8/A9 regulates cell cycle progression and decelerates cancer cell proliferation by arresting at the G2/M checkpoint in a protein phosphatase 2alpha dependent manner. In HNSCC, S100A8 and S100A9 coregulate with gene networks controlling cellular development and differentiation, cell-to-cell signaling, and cell morphology, while S100A8/A9 appears to downregulate expression of invasion- and tumorigenesis-associated genes. Indeed, tumor formation capacity is attenuated in S100A8/A9-expressing carcinoma cells in vivo. Hence, intracellular calprotectin appears to function as a tumor suppressor in head and neck carcinogenesis. When compared with S100A8/A9-low HNSCC based on analysis of TCGA, S100A8/A9-high HNSCC shows significant upregulation of apoptosis-related genes, including multiple caspases. Accordingly, S100A8/A9 facilitates DNA damage responses in HNSCC, promotes apoptotic cell death, and confers sensitivity to cisplatin and X-radiation in vitro. In the tumor milieu, loss of S100A8/A9 strongly associates with poor squamous differentiation and higher tumor grading, EGFR upregulation, increased DNA methylation, and, finally, poorer overall survival for patients with HNSCC.

AB - Under current law, national health spending is projected to grow 5.5 percent annually on average in 2017-26 and to represent 19.7 percent of the economy in 2026. Projected national health spending and enrollment growth over the next decade is largely driven by fundamental economic and demographic factors: changes in projected income growth, increases in prices for medical goods and services, and enrollment shifts from private health insurance to Medicare that are related to the aging of the population. The recent enactment of tax legislation that eliminated the individual mandate is expected to result in only a small reduction to insurance coverage trends. PMID- 29443636 TI - ERRATUM. PMID- 29443635 TI - Race Differences in Linking Family Formation Transitions to Women's Mortality. AB - We examine how the timing and sequencing of first marriage and childbirth are related to mortality for a cohort of 4,988 white and black women born between 1922 and 1937 from the National Longitudinal Survey of Mature Women. We use Cox proportional hazard models to estimate race differences in the association between family formation transitions and mortality. Although we find no relationships between marital histories and longevity, we do find that having children, the timing of first birth, and the sequencing of childbirth and marriage are associated with mortality. White women who had children lived longer than those who had none, but the opposite was found for black women. The effects of birth timing also differed by race; delaying first birth to older ages was protective for white women but not black women. These results underscore the importance of social context in the study of life course transitions. PMID- 29443637 TI - The 2011 Electronic Prescribing Incentive Program. PMID- 29443638 TI - Human Papillomavirus 16 E6 Induces FoxM1B in Oral Keratinocytes through GRHL2. AB - High-risk human papillomavirus (HPV) is a major risk factor for oral and pharyngeal cancers (OPCs), yet the detailed mechanisms by which HPV promotes OPCs are not understood. Forkhead box M1B (FoxM1B) is an oncogene essential for cell cycle progression and tumorigenesis, and it is aberrantly overexpressed in many tumors. We previously showed that FoxM1B was the putative target of an epithelial specific transcription factor, Grainyhead-like 2 (GRHL2). In the current study, we demonstrate that HPV type 16 (HPV-16) E6 induces FoxM1B in human oral keratinocytes (HOKs) and tonsillar epithelial cells (TECs) in part through GRHL2. FoxM1B was barely detectable in cultured normal human oral keratinocytes (NHOKs) and progressively increased in immortalized HOKs harboring HPV-16 genome (HOK 16B) and tumorigenic HOK-16B/BaP-T cells. Retroviral expression of HPV-16 E6 and/or E7 in NHOKs, TECs, and hypopharyngeal carcinoma cells (FaDu) revealed induction of FoxM1B and GRHL2 by the E6 protein but not E7. Both GRHL2 and FoxM1B were strongly induced in the epidermis of HPV-16 E6 transgenic mice and HPV+ oral squamous cell carcinomas. Ectopic expression of FoxM1B led to acquisition of transformed phenotype in HOK-16B cells. Loss of FoxM1B by lentiviral short hairpin RNA vector or chemical inhibitor led to elimination of tumorigenic characteristics of HOK-16B/BaP-T cells. Luciferase reporter assay revealed that GRHL2 directly bound and regulated the FoxM1B gene promoter activity. Using epithelial-specific Grhl2 conditional knockout mice, we exposed wild-type (WT) and Grhl2 KO mice to 4-nitroquinolin 1-oxide (4-NQO), which led to induction of FoxM1B in the tongue tissues and rampant oral tumor development in the WT mice. However, 4-NQO exposure failed to induce tongue tumors or induction of FoxM1B expression in Grhl2 KO mice. Collectively, these results indicate that HPV-16 induces FoxM1B in part through GRHL2 transcriptional activity and that elevated FoxM1B level is required for oropharyngeal cancer development. PMID- 29443644 TI - Accessing and operating agricultural machinery: Advancements in assistive technology for users with impaired mobility. AB - This research focused on the advancements made in enabling agricultural workers with impaired mobility to access and operate off-road agricultural machinery. Although not a new concept, technological advancements in remote-controlled lifts, electronic actuators, electric over hydraulic controllers, and various modes of hand controls have advanced significantly, allowing operators with limited mobility to resume a high level of productivity in agricultural-related enterprises. In the United States, approximately 1.7% of the population is living with some form of paralysis or significant mobility impairment. When paired with the 2012 USDA Agriculture Census of 3.2 million farmers, it can be extrapolated that these technologies could impact 54,000 agricultural workers who have encountered disabling injuries or disease, which inhibit their ability to access and operate tractors, combines, and other self-propelled agricultural machines. Advancements in agricultural-specific technologies can allow for many of these individuals to regain the ability to effectively operate machinery once more. PMID- 29443645 TI - Hair and Salivary Testosterone, Hair Cortisol, and Externalizing Behaviors in Adolescents. AB - Although testosterone is associated with aggression in the popular imagination, previous research on the links between testosterone and human aggression has been inconsistent. This inconsistency might be because testosterone's effects on aggression depend on other moderators. In a large adolescent sample ( N = 984, of whom 460 provided hair samples), we examined associations between aggression and salivary testosterone, hair testosterone, and hair cortisol. Callous-unemotional traits, parental monitoring, and peer environment were examined as potential moderators of hormone-behavior associations. Salivary testosterone was not associated with aggression. Hair testosterone significantly predicted increased aggression, particularly at low levels of hair cortisol (i.e., Testosterone * Cortisol interaction). This study is the first to examine the relationship between hair hormones and externalizing behaviors and adds to the growing literature that indicates that androgenic effects on human behavior are contingent on aspects of the broader endocrine environment-in particular, levels of cortisol. PMID- 29443643 TI - Comprehensive Examination of the Athlete's Shoulder. AB - CONTEXT: Shoulder pain and dysfunction are common, with patients presenting complaints to both primary and orthopaedic physicians. History and physical examination remain essential to creating a differential diagnosis, even as noninvasive imaging has improved. EVIDENCE ACQUISITION: Literature was obtained through keyword searches based on the pathology in question (eg, rotator cuff) and the keywords physical examination using PubMed from January 1, 1980, through September 20, 2017. Additional evidence was obtained through screening references from articles identified through the PubMed searches. STUDY DESIGN: Clinical review. LEVEL OF EVIDENCE: Level 3. RESULTS: A total of 7817 articles were screened for relevance. Several physical examination maneuvers have been described for each specific pathology. The Neer sign has a 75% sensitivity for subacromial impingement (SAI), while the Hawkins-Kennedy test has an 80% sensitivity. The painful arc test has an 80% specificity for SAI. The apprehension test has a hazard ratio of 2.96 for anterior shoulder instability. The Jobe test has a sensitivity of 52.6% and a specificity of 82.4% for full thickness supraspinatus tears, confirmed on arthroscopy. The lag sign is highly sensitive and specific for combined full-thickness supraspinatus and infraspinatus tears at 97% and 93%, respectively. The Speed test has a sensitivity of 54% and specificity of 81% for biceps pathology. The anterior slide test and O'Brien active compression test have been described for superior labrum anterior posterior tears with inconsistent reliability. The cross-body adduction test has a sensitivity of 77% and a specificity of 79% for acromioclavicular joint pathology. CONCLUSION: Several physical examination maneuvers can isolate specific pathology of the shoulder, with widely ranging sensitivity and specificity. PMID- 29443646 TI - Electronic Medical Record-Based Radiation Oncology Toxicity Recording Instrument Aids Benchmarking and Quality Improvement in the Clinic. AB - PURPOSE: The on-treatment visit (OTV) for radiation oncology is essential for patient management. Radiation toxicities recorded during the OTV may be inconsistent because of the use of free text and the lack of treatment site specific templates. We developed a radiation oncology toxicity recording instrument (ROTOX) in a health system electronic medical record (EMR). Our aims were to assess improvement in documentation of toxicities and to develop clinic toxicity benchmarks. METHODS: A ROTOX that was based on National Cancer Institute Common Terminology Criteria for Adverse Events (version 4.0) with flow-sheet functionality was developed in the EMR. Improvement in documentation was assessed at various time intervals. High-grade toxicities (ie, grade >= 3 by CTCAE) by site were audited to develop benchmarks and to track nursing and physician actions taken in response to these. RESULTS: A random sample of OTV notes from each clinic physician before ROTOX implementation was reviewed and assigned a numerical document quality score (DQS) that was based on completeness and comprehensiveness of toxicity grading. The mean DQS improved from an initial level of 41% to 99% (of the maximum possible DQS) when resampled at 6 months post ROTOX. This high-level DQS was maintained 3 years after ROTOX implementation at 96% of the maximum. For months 7 to 9 after implementation (during a 3-month period), toxicity grading was recorded in 4,443 OTVs for 698 unique patients; 107 episodes of high-grade toxicity were identified during this period, and toxicity specific intervention was documented in 95%. CONCLUSION: An EMR-based ROTOX enables consistent recording of treatment toxicity. In a uniform sample of patients, local population toxicity benchmarks can be developed, and clinic response can be tracked. PMID- 29443647 TI - System-Level Health-Care Integration and the Costs of Cancer Care Across the Disease Continuum. AB - PURPOSE: Policy reforms in the Affordable Care Act encourage health care integration to improve quality and lower costs. We examined the association between system-level integration and longitudinal costs of cancer care. METHODS: We used linked SEER-Medicare data to identify patients age 66 to 99 years diagnosed with prostate, bladder, esophageal, pancreatic, lung, liver, kidney, colorectal, breast, or ovarian cancer from 2007 to 2012. We attributed each patient to one or more phases of care (ie, initial, continuing, and end of life) according to time from diagnosis until death or end of study interval. For each phase, we aggregated all claims with the primary cancer diagnosis and identified patients treated in an integrated delivery network (IDN), as defined by the Becker Hospital Review list of the top 100 most integrated health delivery systems. We then determined if care provided in an IDN was associated with decreased payments across cancers and for each individual cancer by phase and across phases. RESULTS: We identified 428,300 patients diagnosed with one of 10 common cancers. Overall, there were no differences in phase-based payments between IDNs and non-IDNs. Average adjusted annual payments by phase for IDN versus non-IDNs were as follows: initial, $14,194 versus $14,421, respectively ( P = .672); continuing, $2,051 versus $2,099 ( P = .566); and end of life, $16,257 versus $16,232 ( P = .948). However, in select cancers, we observed lower payments in IDNs. For bladder cancer, payments at the end of life were lower for IDNs ($11,041 v $12,331; P = .008). Of the four cancers with the lowest 5-year survival rates (ie, pancreatic, lung, esophageal, and liver), average expenditures during the initial and continuing-care phases were lower for patients with liver cancer treated in IDNs. CONCLUSION: For patients with one of 10 common malignancies, treatment in an IDN generally is not associated with lower costs during any phase of cancer care. PMID- 29443648 TI - Readmission Patterns After GI Cancer Hospitalizations: The Medical Versus Surgical Patient. AB - PURPOSE: Readmission within 30 days has been used as a metric for quality of care received at hospitals for certain diagnoses. In the era of accountability, value based care, and increasing cancer costs, policymakers are looking into cancer readmissions as well. It is important to describe the readmission profile of patients with cancer in the most clinically relevant approach to inform policy and health care delivery that can positively impact patient outcomes. PATIENTS AND METHODS: We conducted a retrospective cohort study using linked Texas Cancer Registry and Medicare claims data. We included elderly Texas residents diagnosed with GI cancer and identified risk factors for unplanned readmission using generalized estimating equations, comparing medical with surgical cancer-related hospitalizations. RESULTS: We analyzed 69,693 hospitalizations from 31,736 patients. The unplanned readmission rate was higher after medical hospitalizations than after surgical hospitalizations (21.6% v 13.4%, respectively). Shared risk factors for readmission after medical and surgical hospitalizations included advanced disease stage, high comorbidity index, and emergency room visit and radiation therapy within 30 days before index hospitalization. Several other associated factors and reasons for readmission were noted to be unique to medical or surgical hospitalizations alone. CONCLUSION: Unplanned readmissions among elderly patients with GI cancer are more common after medical hospitalizations compared with surgical hospitalizations. There are shared risk factors and unique risk factors for these hospitalizations that can inform policy, health care delivery, and interventions to reduce readmissions. Other findings underscore the importance of care coordination and comorbidity management in this patient population. PMID- 29443649 TI - Use of Charity Financial Assistance for Novel Oral Anticancer Agents. AB - Novel oral targeted drugs are increasingly used for cancer therapy, but their extreme cost, often exceeding $10,000 per month, poses a significant barrier for patients and insurers alike, leading to the potential breakdown of traditional cost-sharing strategies. Insured patients' routine use of charity assistance to supplement their coverage would indicate a major deficiency in the current health care policies. By using data from a specialty pharmacy affiliated with an academic center (1,557 prescriptions dispensed between January 2014 and March 2017), we examined sources of payment for novel oral anticancer agents, distinguishing contributions from health insurance, patients, and from charitable assistance organizations. Thirty-six percent of 211 patients received charity assistance, including 47% of patients who were 65 years old or older. Charity sources covered 4% of total drug costs and 64% of out-of-pocket expenditures. The proportion of patients receiving financial assistance ranged from 7% when the upfront out-of-pocket requirement was less than $100 to 67% when it exceeded $1,000. When patients' out-of-pocket requirement exceeded $1,000, the median direct cash contribution paradoxically fell to $0 because of extensive use of charity support. Receipt of upfront charity assistance was associated with a longer time to filling the first prescription (median 9 v 7 days; P = .011) and with longer overall duration of therapy (median, 261 v 134 days; P = .014). These findings indicate that high out-of-pocket burden for expensive novel oral anticancer drugs leads to widespread use of charity support in the United States and that a significant financial barrier disparately affects older Medicare beneficiaries. PMID- 29443650 TI - Open Oncology Notes: A Qualitative Study of Oncology Patients' Experiences Reading Their Cancer Care Notes. AB - PURPOSE: Electronic medical records increasingly allow patients access to clinician notes. Although most believe that open notes benefits patients, some suggest negative consequences. Little is known about the experiences of patients with cancer reading their medical notes; thus we aimed to describe this qualitatively. METHODS: We interviewed 20 adults with metastatic or incurable cancer receiving cancer treatment. The semistructured qualitative interviews included four segments: assessing their overall experience reading notes, discussing how notes affected their cancer care experiences, reading a real note with the interviewer, and making suggestions for improvement. We used a constant comparison approach to analyze these qualitative data. RESULTS: We found four themes. Patients reported that notes resulted in the following: (1) increased comprehension; (2) ameliorated uncertainty, relieved anxiety, and facilitated control; (3) increased trust; and (4) for a subset of patients, increased anxiety. Patients described increased comprehension because notes refreshed their memory and clarified their understanding of visits. This helped mitigate the unfamiliarity of cancer, addressing uncertainty and relieving anxiety. Notes facilitated control, empowering patients to ask clinicians more questions. The transparency of notes also increased trust in clinicians. For a subset of patients, however, notes were emotionally difficult to read and raised concerns. Patients identified medical jargon and repetition in notes as areas for improvement. CONCLUSION: Most patients thought that reading notes improved their care experiences. A small subset of patients experienced increased distress. As reading notes becomes a routine part of the patient experience, physicians might want to elicit and address concerns that arise from notes, thereby further engaging patients in their care.

AB - As many biosimilars come to market in the next several years, their use in oncology will play an important role in the future care of patients with cancer. ASCO is committed to providing education and guidance to the oncology community on the use of biosimilars in the cancer setting; therefore, ASCO has developed this statement to offer guidance in the following areas: (1) naming, labeling, and other regulatory considerations, (2) safety and efficacy of biosimilars, (3) interchangeability, switching, and substitution, (4) value of biosimilars, and (5) prescriber and patient education. PMID- 29443652 TI - Placebo-Controlled, Double-Blinded Phase III Study Comparing Dexamethasone on Day 1 With Dexamethasone on Days 1 to 3 With Combined Neurokinin-1 Receptor Antagonist and Palonosetron in High-Emetogenic Chemotherapy. AB - Purpose We evaluated the noninferiority of dexamethasone (DEX) on day 1, with sparing on days 2 and 3, combined with neurokinin-1 receptor antagonist (NK1-RA) and palonosetron (Palo) compared with the 3-day use of DEX in highly-emetogenic chemotherapy (HEC). Patients and Methods Patients who were scheduled to receive HEC (cisplatin >= 50 mg/m2 or anthracycline plus cyclophosphamide) were randomly assigned to receive either DEX on days 1 to 3 (Arm D3) or DEX on day 1 and placebo on days 2 and 3 (Arm D1) combined with NK1-RA and Palo. The primary end point was complete response (CR), defined as no emesis and no rescue medications during the overall (0 to 120 h) phase. The noninferiority margin was set at 15.0% (Arm D1 - Arm D3). Results A total of 396 patients-196 and 200 patients in Arms D3 and D1, respectively-were evaluated. CR rates during the overall period were 46.9% for Arm D3 and 44.0% for Arm D1 (95% CI, -12.6% to 6.8%; P = .007). CR rates during the acute (0 to 24 h) phase were 63.3% and 64.5% for Arms D3 and D1, respectively (95% CI, -8.1% to 10.6%; P < .001), and they were 56.6% and 51.5%, respectively, during the delayed (24 to 120 h) phase (95% CI, -14.8% to 4.6%; P = .023). Hot flushes and tremors were observed more frequently as DEX-related adverse events on days 4 and 5 in Arm D3, whereas anorexia, depression, and fatigue were observed more frequently on days 2 and 3 in Arm D1. As an indication of quality of life, global health status was similar in both arms. Conclusion Antiemetic DEX administration on days 2 and 3 can be spared when combined with NK1-RA and Palo in HEC.

PMID- 29443653 TI - Efficacy of Chemotherapy for ER-Negative and ER-Positive Isolated Locoregional Recurrence of Breast Cancer: Final Analysis of the CALOR Trial. AB - Purpose Isolated locoregional recurrence (ILRR) predicts a high risk of developing breast cancer distant metastases and death. The Chemotherapy as Adjuvant for LOcally Recurrent breast cancer (CALOR) trial investigated the effectiveness of chemotherapy (CT) after local therapy for ILRR. A report at 5 years of median follow-up showed significant benefit of CT for estrogen receptor (ER)-negative ILRR, but additional follow-up was required in ER-positive ILRR. Patients and Methods CALOR was an open-label, randomized trial for patients with completely excised ILRR after unilateral breast cancer. Eligible patients were randomly assigned to receive CT or no CT and stratified by prior CT, hormone receptor status, and location of ILRR. Patients with hormone receptor-positive ILRR received adjuvant endocrine therapy. Radiation therapy was mandated for patients with microscopically involved margins, and anti-human epidermal growth factor receptor 2 therapy was optional. End points were disease-free survival (DFS), overall survival, and breast cancer-free interval. Results From August 2003 to January 2010, 162 patients were enrolled: 58 with ER-negative and 104 with ER-positive ILRR. At 9 years of median follow-up, 27 DFS events were observed in the ER-negative group and 40 in the ER-positive group. The hazard ratios (HR) of a DFS event were 0.29 (95% CI, 0.13 to 0.67; 10-year DFS, 70% v 34%, CT v no CT, respectively) in patients with ER-negative ILRR and 1.07 (95% CI, 0.57 to 2.00; 10-year DFS, 50% v 59%, respectively) in patients with ER positive ILRR ( Pinteraction = .013). HRs were 0.29 (95% CI, 0.13 to 0.67) and 0.94 (95% CI, 0.47 to 1.85), respectively, for breast cancer-free interval ( Pinteraction = .034) and 0.48 (95% CI, 0.19 to 1.20) and 0.70 (95% CI, 0.32 to 1.55), respectively, for overall survival ( Pinteraction = .53). Results for the three end points were consistent in multivariable analyses adjusting for location of ILRR, prior CT, and interval from primary surgery. Conclusion The final analysis of CALOR confirms that CT benefits patients with resected ER-negative ILRR and does not support the use of CT for ER-positive ILRR. PMID- 29443655 TI - Is Interferon-Based Treatment of Viral Hepatitis C Genotype 3 Infection Still of Value in the Era of Direct-Acting Antivirals? AB - The aim of the study is to analyze treatments available for patients infected with genotype (G) 3 hepatitis C virus (HCV) in Poland at the beginning of the interferon (IFN)-free era and evaluate the efficacy and safety of different therapeutic options administered in a real-world setting. We analyzed data of 198 patients who started antiviral therapy after July 1, 2015, and completed it before December 31, 2016; 57.6% of them had liver cirrhosis and 46% were treatment experienced. Fifty percent of patients were assigned to sofosbuvir (SOF)+pegylated IFN alfa (PegIFNa)+ribavirin (RBV), 9% to PegIFNa+RBV, 36% received SOF+RBV, and 5% SOF+daclatasvir (DCV)+/-RBV. Cirrhotic patients were assigned more frequently to IFN-free regimens. Overall, a sustained virological response was achieved by 84.3% of patients in intent-to-treat (ITT) analysis and 87% in modified ITT analysis. For SOF+PegIFNa+RBV and SOF+DCV+/-RBV regimens, the sustained virologic response (SVR) rate reached at least 90%, whereas the two other therapeutic options demonstrated efficacy <80%. The SVR rate in noncirrhotics was higher than in cirrhotics, irrespective of regimen. Adverse events were documented in 52.5%, with the most common being weakness/fatigue and anemia. We confirmed effectiveness and safety of the SOF-based treatment in a real-world cohort of patients with chronic HCV G3 infection. Most notably, we demonstrated good tolerability and high efficacy of the SOF+PegIFNa+RBV regimen. PMID- 29443656 TI - Highlights for Dengue Immunopathogenesis: Antibody-Dependent Enhancement, Cytokine Storm, and Beyond. AB - Infection with dengue virus (DENV) can lead to a wide spectrum of clinical presentations, ranging from asymptomatic infection to death. It is estimated that the disease manifests only in 90 million cases out of the total 390 million yearly infections. Even though research has not yet elucidated which are the precise pathophysiological mechanisms that trigger severe forms of dengue, the infection elicits a critical immune response significant for dengue pathogenesis development. Understanding how the immune response to DENV is established and how it can resolve the infection or turn into an immunopathology is of great importance in DENV research. Currently, studies have extensively debated 2 hypotheses involving immune response: antibody-dependent enhancement and cytokine storm. However, despite its undeniable importance in severe forms of the disease, these 2 hypotheses are based on a primed immune status resulting from previous heterologous infection, abstaining them from explaining the severe forms of dengue in naive immune subjects, for example. Thus, it seems that a more intricate arrangement of causes and conditions must be achieved to severe dengue to occur. Among them, the cytokine network signature elicited, in association with viral aspects deserves special attention regarding the establishment of infection and evolution to pathogenesis. In this work, we intend to shed light on how those elements contribute to severe dengue development. PMID- 29443662 TI - Antiviral Vaccines: Successes and Prospects.

AB - The development of the T- and natural killer (NK) cell growth factor IL-2 has been a sentinel force ushering in the era of immunotherapy in cancer. With the advent of clinical grade recombinant IL-2 in the mid-1980s, oncologists could for the first time directly manipulate lymphocyte populations with systemic therapy. By itself, recombinant IL-2 can induce clinical responses in up to 15% of patients with metastatic cancer or renal cell carcinoma. When administered with adoptively transferred tumor-reactive lymphocytes, IL-2 promotes T cell engraftment and response rates of up to 50% in metastatic melanoma patients. Importantly, these IL-2-driven responses can yield complete and durable responses in a subset of patients. However, the use of IL-2 is limited by toxicity and concern of the expansion of T regulatory cells. To overcome these limitations and improve response rates, other T cell growth factors, including IL-15 and modified forms of IL-2, are in clinical development. Administering T cell growth factors in combination with other agents, such as immune checkpoint pathway inhibitors, may also improve efficacy. In this study, we review the development of T- and NK cell growth factors and highlight current combinatorial approaches based on these reagents.

AB - BACKGROUND: Nusinersen is an antisense oligonucleotide drug that modulates pre messenger RNA splicing of the survival motor neuron 2 ( SMN2) gene. It has been developed for the treatment of spinal muscular atrophy (SMA). METHODS: We conducted a multicenter, double-blind, sham-controlled, phase 3 trial of nusinersen in 126 children with SMA who had symptom onset after 6 months of age. The children were randomly assigned, in a 2:1 ratio, to undergo intrathecal administration of nusinersen at a dose of 12 mg (nusinersen group) or a sham procedure (control group) on days 1, 29, 85, and 274. The primary end point was the least-squares mean change from baseline in the Hammersmith Functional Motor Scale-Expanded (HFMSE) score at 15 months of treatment; HFMSE scores range from 0 to 66, with higher scores indicating better motor function. Secondary end points included the percentage of children with a clinically meaningful increase from baseline in the HFMSE score (>=3 points), an outcome that indicates improvement in at least two motor skills. RESULTS: In the prespecified interim analysis, there was a least-squares mean increase from baseline to month 15 in the HFMSE score in the nusinersen group (by 4.0 points) and a least-squares mean decrease in the control group (by -1.9 points), with a significant between-group difference favoring nusinersen (least-squares mean difference in change, 5.9 points; 95% confidence interval, 3.7 to 8.1; P<0.001). This result prompted early termination of the trial. Results of the final analysis were consistent with results of the interim analysis. In the final analysis, 57% of the children in the nusinersen group as compared with 26% in the control group had an increase from baseline to month 15 in the HFMSE score of at least 3 points (P<0.001), and the overall incidence of adverse events was similar in the nusinersen group and the control group (93% and 100%, respectively). CONCLUSIONS: Among children with later-onset SMA, those who received nusinersen had significant and clinically meaningful improvement in motor function as compared with those in the control group.

AB - Mutations in the polycystin genes, PKD1 or PKD2, results in Autosomal Dominant Polycystic Kidney Disease (ADPKD). Although a genetic basis of ADPKD is established, we lack a clear understanding of polycystin proteins' functions as ion channels. This question remains unsolved largely because polycystins localize to the primary cilium - a tiny, antenna-like organelle. Using a new ADPKD mouse model, we observe primary cilia that are abnormally long in cells associated with cysts after conditional ablation of Pkd1 or Pkd2. Using primary cultures of collecting duct cells, we show that polycystin-2, but not polycystin-1, is a required subunit for the ion channel in the primary cilium. The polycystin-2 channel preferentially conducts K+ and Na+; intraciliary Ca2+, enhances its open probability. We introduce a novel method for measuring heterologous polycystin-2 channels in cilia, which will have utility in characterizing PKD2 variants that cause ADPKD.

METHODS: The participants were ten persisting, ten recovered, and ten nonstuttering children between the ages of 3-5 years; who were classified as persisting, recovered, or nonstuttering approximately 2-2.5 years after the experimental testing took place. The children were exposed to three emotionally-arousing video clips (baseline, positive and negative) and produced a narrative based on a text-free storybook following each video clip. From the audio-recordings of these narratives, individual utterances were transcribed and articulation rates were calculated. RESULTS: Results indicated that persisting children exhibited significantly slower articulation rates following the negative emotion condition, unlike recovered and nonstuttering children whose articulation rates were not affected by either of the two emotion-inducing conditions. Moreover, all stuttering children displayed faster rates during fluent compared to stuttered speech; however, the recovered children were significantly faster than the persisting children during fluent speech. CONCLUSION: Negative emotion plays a detrimental role on the speech-motor control processes of children who persist, whereas children who eventually recover seem to exhibit a relatively more stable and mature speech-motor system. This suggests that complex interactions between speech-motor and emotional processes are at play in stuttering recovery and persistency; and articulation rates following negative emotion or during stuttered versus fluent speech might be considered as potential factors to prospectively predict persistence and recovery from stuttering.

PMID- 29443694 TI - Exploration of two-dimensional bio-functionalized phosphorene nanosheets (black phosphorous) for label free haptoglobin electro-immunosensing applications. AB - We report on the development of an antibody-functionalized interface based on electrochemically active liquid-exfoliated two-dimensional phosphorene (Ph) nanosheets-also known as black phosphorous nanosheets-for the label-free electrochemical immunosensing of a haptoglobin (Hp) biomarker, a clinical marker of severe inflammation. The electrodeposition has been achieved over the screen printed electrode (SPE) using liquid-assisted ultrasonically exfoliated black phosphorus nanosheets. Subsequently, Ph-SPEs bioconjugated with Hp antibodies (Ab), using electrostatic interactions via a poly-L-lysine linker for biointerface development. Electrochemical analysis demonstrates that the Ab modified Ph-SPEs (Ab@Ph-SPE) exhibit enhanced electroconducting behavior as compared to the pristine electrodes. This Ab-functionalized phosphorene-based electrochemical immunosensor platform has demonstrated remarkable sensitivity and specificity, having a dynamic linear response range from 0.01-10 mg ml-1 for Hp in standard and serum samples with a low detection limit (~0.011 mg ml-1) using the label-free electrochemical technique. The sensor electrodes were also studied with other closely relative interferents to investigate cross reactivity and specificity. This strategy opens up avenues to POC (point-of-care) and on-farm livestock disease monitoring technologies for multiplexed diagnosis in complex biological samples such as serum. The technique is simple in fabrication and provides an analytical response in less than 60 s. PMID- 29443692 TI - Executive function and childhood stuttering: Parent ratings and evidence from a behavioral task. AB - PURPOSE: The purpose of this study was to examine the executive function (EF) abilities of preschool children who do (CWS) and do not stutter (CWNS) using a parent-report questionnaire and a behavioral task. METHOD: Participants were 75 CWS and 75 CWNS between the ages of 3;0 and 5;11 (years; months). Parents rated their children's EF abilities using the Behavioral Rating Inventory of Executive Function-Preschool Version (BRIEF-P; Gioia, Espy, & Isquith, 2003). Children's ability to integrate cognitive flexibility, inhibitory control, and working memory was measured using a behavioral task, the Head-Toes-Knees-Shoulders (HTKS; Cameron Ponitz, McClelland, Matthews, & Morrison, 2009). RESULTS: The CWS were judged by their parents as being less proficient in working memory, shift/flexibility, and overall EF than the parents of the CWNS. Children in the CWS group were also 21/2 to 7 times more likely than children in the CWNS group to exhibit clinically significant difficulties with EF. Behavioral task findings revealed that 3-year old CWS performed more poorly than their peers on the HTKS. Parental ratings of executive function and working memory were significantly and moderately correlated with receptive and expressive vocabulary skills only for the CWNS group. CONCLUSION: CWS have more difficulty with EF in everyday life and may experience early delays in their ability to integrate aspects of attention and EF compared to CWNS. PMID- 29443695 TI - Polarized emission from CsPbBr3 nanowire embedded-electrospun PU fibers. AB - Interest in all-inorganic halide perovskites has been increasing dramatically due to their high quantum yield, band gap tunability, and ease of fabrication in compositional and geometric diversity. In this study, we synthesized several hundreds of nanometer long and ~4 nm thick CsPbBr 3 nanowires (NWs). They were then integrated into electrospun polyurethane (PU) fibers to examine the polarization behavior of the composite fiber assembly. Aligned electrospun fibers containing CsPbBr 3 NWs showed a remarkable increase in the degree of polarization from 0.17-0.30. This combination of NWs and PU fibers provides a promising composite material for various applications such as optoelectronic devices and solar cells. PMID- 29443696 TI - Intravenous Lidocaine for Intractable Renal Colic Unresponsive to Standard Therapy. AB - CLINICAL FEATURES: Renal colic is defined as a flank pain radiating to the groin caused by kidney stones in the ureter (urolithiasis). Renal colic is a frequent cause of Emergency Department visits. Most renal colic cases present as acute distress and severe back and/or abdominal pain that require prompt treatment with analgesics. THERAPEUTIC CHALLENGE: Nonsteroidal anti-inflammatory drugs and opioids are traditionally used for renal colic in the Emergency Department. This trend of practice is based on clinical experience and expert opinion. Consensus guidelines that provide evidence-based approach for the management of renal colic are limited. One consensus guideline from Europe provides a systematic approach for the management of pain with the use of nonsteroidal anti-inflammatory drugss and opioids. However, no guidance is provided on how to manage patients who do not respond to these agents. SOLUTION: Intravenous lidocaine 120 mg in 100 mL normal saline was infused over 10 minutes for pain management for intractable renal colic unresponsive to standard therapy. Three minutes after initiation of lidocaine infusion, the patient reported numeric pain rating scale 1/10. At 5 minutes, the reported numeric pain rating scale was 0/10 and remained for 60 minutes after initiation of lidocaine infusion. No adverse events were reported during or after the infusion, and no subsequent analgesia was required.

PMID- 29443699 TI - Grover Disease With Epidermal Dysmaturation Pattern: A Common Histopathologic Finding. AB - BACKGROUND: Grover disease is an entity whose diagnosis is based on clinicopathologic correlation. Histopathologically, focal acantholysis is the most common finding. In some cases, there is prominent squamous atypia which can prove to be very challenging and the lesion may be confused with an epidermal neoplasm. OBJECTIVE: To report on atypical histopathological changes in Grover disease and to provide helpful clues to differentiate between the epidermal atypia seen in some cases of Grover disease and epithelial neoplasms. MATERIAL AND METHODS: We analyzed 33 cases of Grover disease histologically diagnosed at Wake Forest Baptist Medical Center, NC, between 2011 and 2017. Atypical changes in keratinocytes were defined as epithelial buds, nuclear pleomorphism, and dyskeratosis in all layers of epidermis or altered granular layer. RESULTS: Twenty cases (64%) showed foci with alteration of the normal keratinocytic maturation, whereas 18 cases demonstrated nuclear pleomorphism. Buds of epithelial cells emanating from the basal layer of the epidermis and granular cell alteration was present in 19 cases. CONCLUSIONS: The findings especially the presence of an altered granular layer may represent a diagnostic clue in cases of Grover disease with atypical changes.

PMID- 29443701 TI - Association of Polypharmacy with Survival, Complications, and Healthcare Resource Use after Elective Noncardiac Surgery: A Population-based Cohort Study. AB - BACKGROUND: Polypharmacy is increasingly prevalent in older patients and is associated with adverse events among medical patients. The impact of polypharmacy on outcomes after elective surgery is poorly described. The authors' objective was to measure the association of polypharmacy with survival, complications, and resource use among older patients undergoing elective surgery. METHODS: After registration (NCT03133182), the authors identified all individuals older than 65 yr old having their first elective noncardiac surgery in Ontario, Canada, between 2002 and 2014. Using linked administrative data, the authors identified all prescriptions dispensed in the 90 days before surgery and classified people receiving five or more unique medications with polypharmacy. The associations of polypharmacy with 90-day survival (primary outcome), complications, length of stay, costs, discharge location, and readmissions were estimated after multilevel, multivariable adjustment for demographics, comorbidities, previous healthcare use, and surgical factors. Prespecified and post hoc sensitivity analyses were also performed. RESULTS: Of 266,499 patients identified, 146,026 (54.8%) had polypharmacy. Death within 90 days occurred in 4,356 (3.0%) patients with polypharmacy and 1,919 (1.6%) without (adjusted hazard ratio = 1.21; 95% CI, 1.14 to 1.27). Sensitivity analyses demonstrated no increase in effect when only high-risk medications were considered and attenuation of the effect when only prescriptions filled in the 30 preoperative days were considered (hazard ratio = 1.07). Associations were attenuated or not significant in patients with frailty and higher comorbidity scores. CONCLUSIONS: Older patients with polypharmacy represent a high-risk stratum of the perioperative population. However, the authors' findings call into question the causality and generalizability of the polypharmacy-adverse outcome association that is well documented in nonsurgical patients. PMID- 29443702 TI - An Automated Segmentation of R2* Iron-Overloaded Liver Images Using a Fuzzy C Mean Clustering Scheme. AB - OBJECTIVES: The objectives of this study were to develop and test an automated segmentation of R2* iron-overloaded liver images using fuzzy c-mean (FCM) clustering and to evaluate the observer variations. MATERIALS AND METHODS: Liver R2* images and liver iron concentration (LIC) maps of 660 thalassemia examinations were randomly separated into training (70%) and testing (30%) cohorts for development and evaluation purposes, respectively. Two-dimensional FCM used R2* images, and the LIC map was implemented to segment vessels from the parenchyma. Two automated FCM variables were investigated using new echo time and membership threshold selection criteria based on the FCM centroid distance and LIC levels, respectively. The new method was developed on a training cohort and compared with manual segmentation for segmentation accuracy and to a previous semiautomated method, and a semiautomated scheme was suggested to improve unsuccessful results. The automated variables found from the training cohort were assessed for their effectiveness in the testing cohort, both quantitatively and qualitatively (the latter by 2 abdominal radiologists using a grading method, with evaluations of observer variations). A segmentation error of less than 30% was considered to be a successful result in both cohorts, whereas, in the testing cohort, a good grade obtained from satisfactory automated results was considered a success. RESULTS: The centroid distance method has a segmentation accuracy comparable with the previous-best, semiautomated method. About 94% and 90% of the examinations in the training and testing cohorts were automatically segmented out successfully, respectively. The failed examinations were successfully segmented out with thresholding adjustment (3% and 8%) or by using alternative results from the previous 1-dimensional FCM method (3% and 2%) in the training and testing cohorts, respectively. There were no failed segmentation examinations in either cohort. The intraobserver and interobserver variabilities were found to be in substantial agreement. CONCLUSIONS: Our new method provided a robust automated segmentation outcome with a high ease of use for routine clinical application. PMID- 29443704 TI - Lateral Collateral Ligament Injury About the Knee: Anatomy, Evaluation, and Management. AB - The lateral collateral ligament is the primary varus stabilizer of the tibiofemoral joint. Diagnosing an injury to this ligament can be challenging in the setting of multiligamentous trauma; however, failure to recognize these injuries can result in instability of the knee and unsatisfactory outcomes after cruciate ligament reconstruction. Recent literature exploring the anatomy and biomechanics of the lateral collateral ligament has enhanced our understanding and improved diagnosis and management of these injuries. Physical examination and imaging studies also are important in diagnosis and can facilitate classification of lateral collateral ligament tears, which affects treatment decisions. Nonsurgical, reparative, and reconstructive techniques can all be used to manage lateral collateral ligament injury about the knee; the optimal treatment is selected on the basis of injury severity. PMID- 29443703 TI - The Thrower's Shoulder. AB - Overhead athletes subject their shoulders to extreme repetitive torque, compression, distraction, and translation stresses, resulting in adaptive changes of the soft tissues and osseous structures within and around the glenohumeral joint. These anatomic adaptations result in biomechanical enhancements, which improve performance. Understanding the difference between necessary and adaptive changes and pathologic findings is critical when making treatment decisions. Injuries to the shoulder of the overhead athlete can be generally classified into three groups: internal impingement, internal impingement with acquired secondary anterior instability, and primary anterior or multidirectional instability. Although advances in surgical techniques have allowed surgeons to address the pathology in these groups, merely attempting to restore the shoulder to so-called normal can adversely alter adaptive changes that allow high levels of performance.

AB - Advanced imaging has demonstrated that musculoskeletal manifestations of systemic sarcoidosis are more common than previously thought. A definitive strategy for the management of osseous sarcoidosis has not been defined. Some lesions resolve spontaneously, and no systemic medication for sarcoidosis consistently resolves lesions. The orthopaedic surgeon treating patients with musculoskeletal sarcoidosis must make an appropriate diagnosis of bony lesions, seek multidisciplinary input from specialists in pulmonology and rheumatology regarding systemic treatment, and decide when surgery is necessary to prevent dysfunction. PMID- 29443707 TI - Pulmonary Impairment and Risk Assessment in a Diacetyl-Exposed Population: Microwave Popcorn Workers. AB - OBJECTIVES: The butter flavoring additive, diacetyl (DA), can cause bronchiolitis obliterans (BO) by inhalation. A risk assessment was performed using data from a microwave popcorn manufacturing plant. METHODS: Current employees' medical history and pulmonary function tests together with air sampling over a 2.7-year period were used to analyze forced expiratory volume in 1 second (FEV1) and FEV1/forced vital capacity (FVC). The exposure responses for declining pulmonary function and for possible early onset of BO were estimated using multiple regression methods. Several exposure metrics were investigated; benchmark dose and excess lifetime risk of impairment were calculated. RESULTS: Forty-six percent of the population had less than 6 months exposure to DA. Percent-of predicted FEV1 declined with cumulative exposure (0.40 per ppm-yr, P < 10) as did percent FEV1/FVC (0.13 per ppm-yr, P = 0.0004). Lifetime respiratory impairment prevalence of one per thousand resulted from 0.005 ppm DA and one per thousand lifetime incidence of impairment was predicted for 0.002 ppm DA. CONCLUSION: DA exposures, often exceeding 1 ppm in the past, place workers at high risk of pulmonary impairment.

AB - OBJECTIVE: We aimed to test the impact of the Worksite Heart Health Improvement Project (WHHIP) on cardiovascular risk factors among long-term care staff. METHODS: The WHHIP was an 18-month cluster randomized control trial conducted in four long-term care facilities (n = 98). RESULTS: A significant positive delayed intervention effect for diastolic blood pressure was seen in the intervention group (80.34 mm/Hg [standard deviation {SD} = 6.10] at baseline to 73.08 mm/Hg [SD = 4.99] at 18-months; P = <0.001). Whereas, a significant negative intervention effect was seen for steps with a mean increase from 5807.18 (SD = 3934.30) steps at baseline to 7839.19 (SD = 3126.09) steps at 18-months (P = 0.022) as well as body mass index with a mean change from 29.86 (SD = 7.38) at baseline to 26.67 (SD = 5.29) at 18-months (P = 0.045) in the education only group. CONCLUSION: The WHHIP demonstrated the ability to impact participants' blood pressure over time. PMID- 29443709 TI - General Information on Clinical Psychopharmacology in China.

PMID- 29443716 TI - Time for an Acute Focus on Chronic Care in Undergraduate Medical Education. AB - As the burdens of chronic disease rise in the United States, both undergraduate and graduate medical education must adapt to adequately equip future physicians with the skills to manage the increasingly complex health needs affecting the population. However, traditional models of undergraduate medical education (UME) have made focusing on chronic care education challenging. In this Invited Commentary, the authors advocate for strengthening UME based on five approaches to engage trainees in learning about chronic care across both the preclinical and clinical phases of their education: (1) introducing chronic care in the preclinical years; (2) prioritizing chronic care education across all specialties; (3) maximizing the fourth year of medical school through a chronic care focus; (4) creating chronic-disease-focused advanced clerkships; and (5) leveraging technology for education. These five approaches call for restructuring of both preclinical and clinical education to more comprehensively emphasize the skills and knowledge needed for trainees to manage chronic diseases. Such efforts will ensure that graduating medical students are well versed in the competencies needed to effectively care for patients with chronic conditions in advance of their transition to graduate medical education and clinical practice. PMID- 29443717 TI - Anticipating and Training the Physician of the Future: The Importance of Caring in an Age of Artificial Intelligence. AB - Artificial intelligence and other forms of information technology are only just beginning to change the practice of medicine. The pace of change is expected to accelerate as tools improve and as demands for analyzing a rapidly growing body of knowledge and array of data increase. The medical students of today will practice in a world where information technology is sophisticated and omnipresent. In this world, the tasks of memorization and analysis will be less important to them as practicing physicians. On the other hand, the nonanalytical, humanistic aspects of medicine-most importantly, the art of caring-will remain a critical function of the physician, and facility with improving systems of care will be required. Communication, empathy, shared decision making, leadership, team building, and creativity are all skills that will continue to gain importance for physicians. These skills should be further prioritized in medical school curricula to produce an even more effective physician for the future.

PMID- 29443719 TI - The Time Is Now: Using Graduates' Practice Data to Drive Medical Education Reform. AB - Medical educators are not yet taking full advantage of the publicly available clinical practice data published by federal, state, and local governments, which can be attributed to individual physicians and evaluated in the context of where they attended medical school and residency training. Understanding how graduates fare in actual practice, both in terms of the quality of the care they provide and the clinical challenges they face, can aid educators in taking an evidence based approach to medical education. Although in their infancy, efforts to link clinical outcomes data to educational process data hold the potential to accelerate medical education research and innovation. This approach will enable unprecedented insight into the long-term impact of each stage of medical education on graduates' future practice. More work is needed to determine best practices, but the barrier to using these public data is low, and the potential for early results is immediate. Using practice data to evaluate medical education programs can transform how the future physician workforce is trained and better align continuously learning medical education and health care systems. PMID- 29443720 TI - Retained Guidewires in the Veterans Health Administration: Getting to the Root of the Problem. AB - OBJECTIVES: The aims of this study were to investigate the demographics, causes, and contributing factors of retained guidewires (GWs) and to make specific recommendations for their prevention. METHODS: The Veterans Administration patient safety reporting system database for 2000-2016 was queried for cases of retained GWs (RGWs). Data extracted for each case included procedure location, provider experience, insertion site, urgency, time to discovery, root causes, and corrective actions taken. RESULTS: There were 101 evaluable cases of RGWs. Resident trainee (36%), critical care unit (38%), femoral vein (44%), and nonemergent placement (79%) were the conditions most frequently associated with a RGW. While discovery occurred almost immediately (30%) or in next 24 hours (31%), there were instances of RGWs found months (2%) or years (3%) later. Common root causes included inexperience (46%), lack of standardization (35%), distractions (25%), and lack of a checklist (23%). CONCLUSIONS: The results demonstrate the result of human factors-based errors such as posttask completion errors. We recommend human factor-based interventions such as checklists and devices employing forcing functions that do not allow clinicians to complete the insertion process without first removing the GW. PMID- 29443721 TI - Psychometric Properties of Korean Version of the Second Victim Experience and Support Tool (K-SVEST). AB - OBJECTIVES: "Second victims" are defined as healthcare professionals whose wellness is influenced by adverse clinical events. The Second Victim Experience and Support Tool (SVEST) was used to measure the second-victim experience and quality of support resources. Although the reliability and validity of the original SVEST have been validated, those for the Korean tool have not been validated. The aim of the study was to evaluate the psychometric properties of the Korean version of the SVEST. METHODS: The study included 305 clinical nurses as participants. The SVEST was translated into Korean via back translation. Content validity was assessed by seven experts, and test-retest reliability was evaluated by 30 clinicians. Internal consistency and construct validity were assessed via confirmatory factor analysis. The analyses were performed using SPSS 23.0 and STATA 13.0 software. RESULTS: The content validity index value demonstrated validity; item- and scale-level content validity index values were both 0.95. Test-retest reliability and internal consistency reliability were satisfactory: the intraclass consistent coefficient was 0.71, and Cronbach alpha values ranged from 0.59 to 0.87. The CFA showed a significantly good fit for an eight-factor structure (chi = 578.21, df = 303, comparative fit index = 0.92, Tucker-Lewis index = 0.90, root mean square error of approximation = 0.05). CONCLUSIONS: The K-SVEST demonstrated good psychometric properties and adequate validity and reliability. The results showed that the Korean version of SVEST demonstrated the extent of second victimhood and support resources in Korean healthcare workers and could aid in the development of support programs and evaluation of their effectiveness. PMID- 29443722 TI - Characterizing Treatment Utilization Patterns for Trigeminal Neuralgia in the United States. AB - BACKGROUND AND AIM: Trigeminal neuralgia (TN) is a rare orofacial disorder characterized by severe unilateral paroxysmal pain in the region of the fifth cranial nerve. Clinical guidelines recommend carbamazepine (only US Food and Drug Administration-approved drug for TN) and oxcarbazepine as first-line therapies. We utilized the US Truven Health MarketScan database to examine treatment patterns among patients with TN. METHODS: Included patients were aged 18 years and above, newly diagnosed with TN (>=2 TN diagnoses >=14 days apart; no diagnosis in the previous year), continuously enrolled 1 year before index, with >=3 years' follow-up postindex. We assessed utilization of selected pharmacotherapies (carbamazepine, oxcarbazepine, pregabalin, gabapentin, baclofen, duloxetine, topiramate), surgery (posterior fossa, radiosurgery), and injections (peripheral anesthetic injections, Gasserian ganglion procedures) for TN. RESULTS: In total, 3685 patients were included (2425 commercial, 1260 Medicare; 71.8% female; age, mean [SD], 59 [15] y). Overall, 72.5% of patients received at least 1 studied medication, most commonly carbamazepine (51.7%) or gabapentin (48.6%). In total, 65% of pharmacologically treated patients had >=2 treatment episodes; 41.6% had >=3 (defined by a change in pharmacotherapy [monotherapy/combination] regimen). Overall, 12.3% had surgery and 7.3% injections; 42.9% received opioids for TN. CONCLUSIONS: In the 3 years after diagnosis, patients with TN in the United States receive a variety of pharmacological treatments, including opioids, despite carbamazepine being the only approved medication. A notable proportion utilize surgeries/injections. A high proportion of pharmacologically treated patients receive multiple treatment episodes, suggesting frequent therapy switching, perhaps because of suboptimal efficacy/tolerability. Our data suggest a high burden of illness associated with TN. PMID- 29443723 TI - Neurophysiological Pain Education for Patients With Chronic Low Back Pain: A Systematic Review and Meta-Analysis. AB - OBJECTIVE: To evaluate the effect of neurophysiological pain education (NPE) for patients with chronic low back pain (CLBP). METHODS: A systematic search was performed in 6 electronic databases. Eligible randomized-controlled trials were those with at least 50 % of patients with CLBP and in which NPE was compared with no intervention or usual care. Methodological quality was assessed independently by 2 of the authors using the Cochrane Collaboration Risk of Bias Tool. The effect of NPE was summarized in a random effect meta-analysis for pain, disability, and behavioral attitudes. Effect was estimated as weighted mean difference (WMD) if outcomes were on the same scale or as standardized mean difference (SMD). The overall quality of evidence was evaluated according to GRADE guidelines. RESULTS: Seven randomized-controlled trial studies (6 low and 1 high quality) were included. Statistically significant differences in pain, in favor of NPE, were found after treatment, WMD=-1.03 (95% confidence interval [CI], -0.55 to -1.52), and after 3 months, WMD=-1.09 (95% CI, -2.17 to 0.00). Furthermore statistically significant lower disability was found in the NPE group after treatment, SMD=-0.47 (95% CI, -0.80 to -0.13) and after 3 months SMD=-0.38 (95% CI, -0.74 to -0.02). The difference in favor of NPE in reduction in Tampa Scale of Kinesiophobia was not statistically significant, WMD=-5.73 (95% CI, 13.60 to 2.14) and after 3 months WMD=-0.94 (95% CI, -6.28 to 4.40). DISCUSSION: There was moderate evidence supporting the hypothesis that NPE has a small to moderate effect on pain and low evidence of a small to moderate effect on disability immediately after the intervention. NPE has a small to moderate effect on pain and disability at 3 months follow-up in patients with CLBP. PMID- 29443724 TI - Preoperative fasting guidelines in pediatric anesthesia: are we ready for a change? AB - PURPOSE OF REVIEW: Study after study shows that prolonged fasting before anesthesia is common in children. Pediatric anesthesiologists around the world are concerned that the current guidelines may be part of the problem. This review focuses on what can be done about it. RECENT FINDINGS: We discuss new insights into the physiology of gastric emptying of different categories of food and drink. The evidence for negative effects of prolonged fasting occurring in spite of implementation of the current guidelines is examined. We also critically appraise the concept of a strict association between fasting time and the risk of aspiration and discuss recent studies in which children have been allowed clear fluids less than 2 h before anesthesia induction. SUMMARY: Accumulating evidence indicates that changes of the current guidelines for preoperative fasting should be considered for children undergoing elective procedures. VIDEO ABSTRACT. PMID- 29443725 TI - Pediatric anesthesia after APRICOT (Anaesthesia PRactice In Children Observational Trial): who should do it? AB - PURPOSE OF REVIEW: This review highlights the requirements for harmonization of training, certification and continuous professional development and discusses the implications for anesthesia management of children in Europe. RECENT FINDINGS: A large prospective cohort study, Anaesthesia PRactice In Children Observational Trial (APRICOT), revealed a high incidence of perioperative severe critical events and a large variability of anesthesia practice across 33 European countries. Relevantly, quality improvement programs have been implemented in North America, which precisely define the requirements to manage anesthesia care for children. These programs, with the introduction of an incident-reporting system at local and national levels, could contribute to the improvement of anesthesia care for children in Europe. SUMMARY: The main factors that likely contributed to the APRICOT study results are discussed with the goal of defining clear requirement guidelines for anesthetizing children. Emphasis is placed on the importance of an incident-reporting system that can be used for both competency-based curriculum for postgraduate training as well as for continuous professional development. Variability in training as well as in available resources, equipment and facilities limit the generalization of some of the APRICOT results. Finally, the impact on case outcome of the total number of pediatric cases attended by the anesthesiologist should be taken into consideration along with the level of expertise of the anesthesiologist for complex pediatric anesthesia cases.

PMID- 29443727 TI - Acute bilateral retina hemorrhages beneath internal limiting membrane: An unusual ophthalmological case report of acute leukemia during complete clinical remission. AB - RATIONALE: Leukemia is a common hematologic disease that causes various systemic complications, such as ophthalmological disorders. The venous congestion is considered to be the main clinical sign that occurs during the initial stage of the disease, whereas white-centered hemorrhages are the most typical manifestations in leukemic retinopathy. These complications usually manifest when the disease presents with clinical and hematological symptoms. In the present study, we report a patient who was diagnosed with leukemic retinopathy. The initial signs of this disease were bilateral hemorrhages that occurred during complete clinical remission. Previous studies regarding this condition are quite rare. PATIENT CONCERNS: We report a 26-year-old man who was diagnosed with leukemic retinopathy and exhibited the initial signs of the disease, namely bilateral hemorrhages with a distinct appearance beneath the internal limiting membrane. In addition, flame-shaped hemorrhages were observed surrounding the optic discs and/or along the vessels in the absence of venous congestion. All these changes were present during complete clinical remission. DIAGNOSES: Bilateral acute leukemic retinopathy, acute lymphoblastic leukemia (pro-B lymphocyte, BCR-ABL chimeric gene-positive). INTERVENTIONS: Clinical remission was achieved following effective systemic chemotherapy that was applied for leukemia in the hematology department. A dynamic observation was applied actively in the absence of surgery and/or medical treatment for ophthalmologic treatment. OUTCOMES: Best corrected visual acuity was 20/40 in the right eye and 20/60 in the left eye, which was considerably better than those noted at the initial visit of the patient (20/250 in the right eye and 20/400 in the left eye). LESSONS: The cautious expectant treatment is safe and helpful for acute leukemic retinopathy. A long-term follow-up is inevitable. Effective systemic chemotherapy that is required for leukemia treatment can achieve clinical remission, which might be helpful in controlling the pathological changes of the eyes.

AB - RATIONALE: We report on a patient with traumatic brain injury who showed motor recovery concurrent with recovery of injured corticofugal tracts (CFTs), diagnosed by diffusion tensor tractography (DTT). PATIENT CONCERNS: Four weeks after onset, when the patient started rehabilitation, he showed severe weakness of both upper and lower extremities [Motricity Index (MI, full score: 100/100): 9/30]. DIAGNOSES: A 29-year-old male patient underwent conservative management for traumatic hemorrhages in both frontal lobes and right thalamus resulting from a car accident. INTERVENTIONS: The patient participated in a comprehensive rehabilitative management program, including movement therapy, dopaminergic drugs for improvement of apraxia (pramipexole: 2.5mg, amantadine: 300mg, ropinirole: 0.75 mg, and levodopa: 500mg), and neuromuscular electrical stimulation therapy of the right elbow extensors, finger extensors, both knee extensors, and ankle dorsiflexors. OUTCOMES: After 2 months' intensive rehabilitation, his motor weakness rapidly recovered to the point that he was able to move all 4 extremities against some resistance (MI: 75/75). The right supplementary motor area (SMA)-CFT showed narrowing and partial tearing in the upper portion on 1 month DTT, and became thicker on 3-month DTT. Compared to the 12 normal control subjects, the fractional anisotropy (FA) values of the right corticospinal tract and both dorsal premotor cortex-CFT were more than 1 standard deviation lower than those of normal control subjects on both 1- and 3-month DTTs. LESSONS: Although the tract volume of the right SMA-CFT was more than 1 standard deviation lower than normal control subjects on 1-month DTT, it increased to within 1 standard deviation on 3-month DTT. Recovery of the injured SMA-CFT concurrent with motor recovery was demonstrated in a patient with traumatic brain injury. PMID- 29443732 TI - Curcumin induces apoptosis and inhibits proliferation in infantile hemangioma endothelial cells via downregulation of MCL-1 and HIF-1alpha. AB - BACKGROUND: Curcumin has been used as an alternative medicine for the treatment of infantile hemangiomas (IHs); however, the mechanism underlying the effectiveness of curcumin in IHs remains largely unclear. METHODS: In this study, we isolated primary human hemangioma endothelial cells (HemECs) from fresh surgical specimens of 3 patients. We treated HemECs by curcumin and investigated the alterations in proliferative and apoptotic signaling pathways with cell counting kit-8, flow cytometry, western blotting, immunofluorescence, and real time polymerase chain reaction. RESULTS AND CONCLUSION: We found that curcumin potently inhibited proliferation in HemECs, achieving low-micromolar IC50 (the half maximal inhibitory concentration) value. We also observed that treatment with curcumin induced apoptosis in HemECs, as evidenced by positively Annexin-V FITC staining, caspase-3 activation, and cleavage of poly(adenosine diphosphate ribose) polymerase (PARP) in the treated cells. Moreover, we showed that curcumin suppressed the expression of antiapoptotic protein myeloid cell leukemia-1 (MCL 1), hypoxia-inducible factor 1alpha (HIF-1alpha), and vascular endothelial growth factor (VEGF).Altogether, our study suggests that the effectiveness of curcumin in IHs may be associated with its potent antiproliferative and apoptotic activities in HemECs. PMID- 29443733 TI - Serial evaluation of the SOFA score is reliable for predicting mortality in acute severe pancreatitis. AB - Acute severe pancreatitis caused high mortality, and several scoring systems for predicting mortality are available. We evaluated the effectiveness of serial measurement of several scoring systems in patients with acute severe pancreatitis.We retrospectively obtained serial measurements of Ranson, Acute Physiology and Chronic Health Assessment (APACHE) II, and Sequential Organ Failure Assessment (SOFA) scores of 159 patients with acute severe pancreatitis.The overall mortality rate was 20%, and early mortality (in the first 2 weeks) occurred in 10 (7.4%) patients, while late mortality occurred in 17 (12.6%).All scoring systems were reliable for predicting overall and intensive care unit mortality, while the SOFA score on day 7 presented the largest area under the receiver operator characteristic (ROC) curve (0.858, SE 0.055). Changes in scores over time were evaluated for predicting the progression of organ failure, and the change in SOFA score on hospital day 7 or no interval change in SOFA score was associated with higher mortality rates.APACHE II and SOFA scores are both sensitive for predicting mortality in acute pancreatitis. The serial SOFA scores showed reliable for predicting mortality. Hospital day 7 is a reasonable time for SOFA score reassessment to predict late mortality in acute severe pancreatitis. PMID- 29443734 TI - Prognostic significance of pulmonary hypertension in patients with cystic fibrosis: A systematic review and meta-analysis. AB - BACKGROUND AND OBJECTIVE: Pulmonary hypertension (PH) is frequently found in advanced parenchymal lung diseases like cystic fibrosis (CF), but the role played by PH in the clinical outcome of CF patients remains unclear. The aim of this study is to determine the influence of PH on survival in the CF population by meta-analysis. METHODS: Publications addressing the associations between PH and overall survival (OS) or other clinical characteristics in CF patients were selected from electronic databases. Odds ratios (ORs) or mean differences (MDs) were used to estimate the association between PH and the clinical characteristics. The hazard ratios (HRs) with 95% confidence interval (CI) were abstracted or calculated to evaluate the association between PH and CF survival outcome. Subgroup analyses were also conducted. RESULTS: Seven studies including 2141 CF patients who met the inclusion criteria were included in our meta analysis. With respect to clinical features, PH was significantly associated with lower PaO2 (P < .001), higher PaCO2 (P = .02), lower forced expiratory volume in 1 second percent (P < .001) and lower forced vital capacity percent (P < .001). However, PH had no significant impact on CF patients' OS (HR = 1.29, 95% CI 0.81 to 2.06, P = .283). Furthermore, subgroup analyses also showed no evidence of prognostic role of PH in CF patients (all P values >.05). CONCLUSIONS: Our findings suggest that the presence of PH was strongly correlated with worse blood gas parameters and worse lung function, but surprisingly had no significant prognostic value on survival among CF patients. Further large-scale and prospective studies are needed to confirm these findings. PMID- 29443735 TI - Identification of gene expression models for laryngeal squamous cell carcinoma using co-expression network analysis. AB - One of the most common head and neck cancers is laryngeal squamous cell carcinoma (LSCC). LSCC exhibits high mortality rates and has a poor prognosis. The molecular mechanisms leading to the development and progression of LSCC are not entirely clear despite genetic and therapeutic advances and increased survival rates. In this study, a total of 116 differentially expressed genes (DEGs), including 11 upregulated genes and 105 downregulated genes, were screened from LSCC samples and compared with adjacent noncancerous. Statistically significant differences (log 2-fold difference > 0.5 and adjusted P-value < .05) were found in this study in the expression between tumor and nontumor larynx tissue samples. Nine cancer hub genes were found to have a high predictive power to distinguish between tumor and nontumor larynx tissue samples. Interestingly, they also appear to contribute to the progression of LSCC and malignancy via the Jak-STAT signaling pathway and focal adhesion. The model could separate patients into high risk and low-risk groups successfully when only using the expression level of mRNA signatures. A total of 4 modules (blue, gray, turquoise, and yellow) were screened for the DEGs in the weighted co-expression network. The blue model includes cancer-specific pathways such as pancreatic cancer, bladder cancer, nonsmall cell lung cancer, colorectal cancer, glioma, Hippo signaling pathway, melanoma, chronic myeloid leukemia, prostate cancer, and proteoglycans in cancer. Endocrine resistance (CCND1, RAF1, RB1, and SMAD2) and Hippo signaling pathway (CCND1, LATS1, SMAD2, and TP53BP2) could be of importance in LSCC, because they had high connectivity degrees in the blue module. Results from this study provide a powerful biomarker discovery platform to increase understanding of the progression of LSCC and to reveal potential therapeutic targets in the treatment of LSCC. Improved monitoring of LSCC and resulting improvement of treatment of LSCC might result from this information. PMID- 29443736 TI - What may cause fetus loss from acute pancreatitis in pregnancy: Analysis of 54 cases. AB - Acute pancreatitis in pregnancy (APIP) poses a serious threat to the mother and her fetus, and might lead to fetal loss including miscarriage and stillbirth in certain patients. We sought to identify possible factors that affect fetal distress and evaluated outcomes of patients with APIP.We retrospectively reviewed clinical records of 54 pregnant women with APIP, who were treated at 2 tertiary clinical centers over a 6-year period. Clinical characteristics including etiology and severity of APIP, fetal monitoring data, and maternofetal outcomes were analyzed.Etiology of APIP included acute biliary pancreatitis (ABP, n = 14), hyperlipidemic pancreatitis (HLP, n = 22), and other etiologies (n = 18). Severity was classified as mild acute pancreatitis (MAP, n = 23), moderately severe acute pancreatitis (MSAP, n = 24), and severe acute pancreatitis (SAP, n = 7). The incidence of preterm delivery, fetal distress, and fetal loss increased with the progression of severity of APIP (P < .05). The severity of HLP was significantly higher than that of ABP and APIP of other etiology (P < .01). HLP was more likely to lead to fetal distress than other APs (P < .01). Only 12 (22.2%) patients had fetal monitoring including non-stress test (NST); 1 case of SAP (14.3%) and 15 cases of MSAP (62.5%) were not transferred to intensive care unit for intensive monitoring.The incidence of fetal distress and fetal loss increased with worsening of APIP severity. HLP tends to result in worse fetal outcomes. The deficiencies of fetal state monitoring, lack of assessment, and management of pregnant women might increase the fetal loss in APIP. PMID- 29443737 TI - Effect of tenofovir on renal function in patients with chronic hepatitis B. AB - Tenofovir disoproxil fumarate (TDF) is widely used to treat patients with hepatitis B virus (HBV) infection. We investigated the effect of TDF on renal insufficiency in patients with chronic hepatitis B (CHB).A consecutive cohort analysis was applied to CHB patients taking prescribed TDF from January 2012 to May 2016 at Soonchunhyang University Seoul Hospital. Alterations over time in corrected calcium, phosphate, creatinine, and estimated glomerular filtration rate (eGFR) were analyzed using the generalized estimating equation method. The percentage increase in creatinine from baseline to the maximum creatinine level (delta creatinine) was compared according to the underlying disease using the Mann-Whitney U test. Cox proportional hazard regression model was used to determine risk factors associated with renal insufficiency.The baseline creatinine, eGFR, corrected calcium, and phosphate levels were 0.72 +/- 0.01 mg/dL (mean +/- SD), 106.37 +/- 1.06 mL/min/1.73 m, 8.82 +/- 0.04 mg/dL, and 3.42 +/- 0.05 mg/dL, respectively. The creatinine level had increased significantly at 12, 24, 48, 72, and 96 weeks, while the eGFR level had decreased significantly at these 5 time points. Multivariate analysis confirmed that age >=60 years and the baseline bilirubin level were independently associated with the risk of renal insufficiency. Delta creatinine was significantly higher in patients with diabetes mellitus (DM) than in patients without DM.Renal function was decreased from baseline in CHB patients receiving TDF therapy, which indicates that the renal function of patients undergoing treatment with TDF should be monitored regularly. Old age, DM, and serum bilirubin were risk factors for the development of renal insufficiency in CHB patients receiving TDF therapy. PMID- 29443738 TI - Hodgkin lymphoma involving the tonsil misdiagnosed as tonsillar carcinoma: A case report and review of the literature. AB - RATIONALE: Primary Hodgkin lymphoma (HL) involving the tonsil is extremely rare. Only about 20 such cases with verification of biopsy and immunohistochemistry have been reported. Because of its rarity and unremarkable clinical presentation, a timely correct diagnosis is very challenging. PATIENT CONCERNS: A 43-year-old man complained left tonsillar enlargement and painless masses in left neck, with night sweat. The clinical examination found a marked tonsillar asymmetry, with an enlarged left tonsil and ipsilateral cervical lymphadenopathy and a normal right tonsil. DIAGNOSIS: The patient was initially regarded as tonsillar lymphoepithelial carcinoma. INTERVENTIONS: The patient received a resection of left tonsil and left cervical masses and then was definitively diagnosed as HL (IIEB). He was managed by 6 cycles of chemotherapy (adriamycin, bleomycin, vinblastine, and dacarbazine) and radiotherapy to the Waldeyer ring. OUTCOMES: The patient has been disease free for more than 3 years after diagnosis. LESSONS: As the reason of an extreme rare occurrence of HL involving the tonsil, doctors can easily misdiagnose the disease as tonsillar lymphoepithelial carcinoma. This case serves as a reminder important role of biopsy. PMID- 29443739 TI - Effects of exercise on secretion transport, inflammation, and quality of life in patients with noncystic fibrosis bronchiectasis: Protocol for a randomized controlled trial. AB - BACKGROUND: Bronchiectasis is characterized by pathological and irreversible bronchial dilatation caused by the inefficient mucus and microorganism clearance and progression of inflammatory processes. The most frequent characteristic is the increase in bronchial mucus production resulting in slower transport and damage to the mucociliary transport. AIMS: To evaluate the effects of exercise on mucus transport, inflammation, and resistance of the respiratory and autonomic nervous systems and subsequent effects on quality of life in patients with bronchiectasis who are enrolled in a pulmonary rehabilitation program. METHODS: Sixty subjects of both sexes between 18 and 60 years (30 volunteers with clinically stable bronchiectasis and 30 healthy volunteers) will be included. Participants with chronic obstructive pulmonary disease, decompensated cardiovascular or metabolic diseases, neuromuscular and musculoskeletal diseases, and active smokers will be excluded. Volunteers will be randomly allocated to the pulmonary rehabilitation or control groups. The primary outcomes will be nasal transport time as evaluated by nasal saccharin transport time, analysis of nasal lavage, enzyme immunoassay of exhaled expiration, and analysis of the mucus properties. The secondary outcomes will include pulmonary function tests, impulse oscillometry, heart rate variability analysis, and quality of life questionnaires. DISCUSSION: In addition to the benefits for patients already described in the literature, the additional benefit of mucus removal may contribute to optimizing treatments and better control of the disease. CONCLUSION: This protocol could provide new information about the unclear mechanisms regarding exercise to aid in the removal of secretions. PMID- 29443740 TI - Clinical outcomes of left main coronary artery disease patients undergoing three different revascularization approaches. AB - Significant unprotected left main (LM) coronary artery disease is frequently associated with severe multivessel disease and increased mortality and morbidity compared with non-LM coronary artery disease. This study compared the clinical outcomes of patients with LM disease who received percutaneous coronary intervention (PCI) with stenting, conventional coronary-artery bypass grafting (C CABG), and robot-assisted CABG (R-CABG).This retrospective study analyzed 472 consecutive LM disease patients who underwent three different revascularization approaches at a tertiary medical center between January 2005 and November 2013.Of the 472 LM disease patients, 139 received R-CABG, 147 received C-CABG, and 186 received PCI. The need for target vessel revascularization (TVR) was highest in the PCI group. The R-CABG group had significantly lower rates of in-hospital and follow-up all-cause deaths compared with the other 2 groups (1.4% vs. 3.4% and 9.7%, P = .0058; 13.7% vs. 29.3% and 29.6%, P = .0023, respectively). Patients in the R-CABG group had significantly lower rates of intra-aortic balloon pump assistance, and shorter duration of ICU and total hospital stay compared to patients in the C-CABG group. However, revascularization modality, SYNTAX scores, and residual SYNTAX scores were not independent predictors of in-hospital or long term mortality.In this cohort of LM disease patients treated at a tertiary medical center, PCI is a reasonable choice in patients with less lesion complexity but who are older and have comorbidities. R-CABG is feasible in stable LM disease patients with high SYNTAX scores, and is an effective alternative to C CABG in LM disease patients with few risk factors. However, revascularization modality per se was not a determinant for long-term mortality in our real-world practice. PMID- 29443741 TI - Research progress of asymptomatic bacteriuria before arthroplasty: A systematic review. AB - BACKGROUND: A high prevalence of asymptomatic bacteriuria exists in patients prior to arthroplasty, and urinary tract infection is considered to be a source of postoperative superficial wound and prosthetic joint infections. There is no consensus whether to screen for and treat asymptomatic bacteriuria before arthroplasty. OBJECTIVE: To summarize the association between asymptomatic bacteriuria and complications after arthroplasty and to evaluate the clinical benefits of treating asymptomatic bacteriuria prior to arthroplasty. METHOD: We systematically searched PubMed, Embase, and the Cochrane Library to retrieve potentially eligible articles. By screening the titles and abstracts of retrieved records and then reading the full texts of the remaining papers, we finally included 8 English-language articles in this systematic review. RESULTS: Asymptomatic bacteriuria prior to arthroplasty is significantly associated with an increased occurrence of postoperative prosthetic joint and superficial wound infections. However, there is little evidence for direct or hematogenous seeding of urinary infections, and treating asymptomatic bacteriuria before arthroplasty did not decrease the incidence of postoperative infectious complications. CONCLUSION: Asymptomatic bacteriuria is not a contraindication for arthroplasty, and the practice of routine preoperative screening for and treatment of asymptomatic bacteriuria should not be continued. PMID- 29443742 TI - Ghost cell odontogenic carcinoma with suspected cholesterol granuloma of the maxillary sinus in a patient treated with combined modality therapy: A case report and the review of literature. AB - RATIONALE: Ghost cell odontogenic carcinoma (GCOC) is a rare malignant odontogenic tumor with aggressive growth characteristics. PATIENT CONCERNS: A 41 year-old Chinese male visited our hospital in 2013, with a 4-month history of bloody purulent rhinorrhea with a peculiar smell in the right nasal cavity. DIAGNOSES: The patient suffered from recurrent GCOC with suspected cholesterol granuloma of the maxillary sinus. The patient was incorrectly diagnosed with a calcifying epithelial odontogenic tumor at his first recurrence. Physical examination, radiological examination, and histopathology were used to identify GCOC. INTERVENTIONS: Considering the recurrence of GCOC and poor effects of single surgery, postoperative adjuvant chemotherapy and concurrent chemoradiotherapy were performed after radical surgical excision. OUTCOMES: So far, no significant evidence has suggested recurrence or metastasis after a long term follow-up. LESSONS: We advocate wide surgery with clean margins at the first accurate diagnosis. Combined modality therapy could be taken for the recurrent GCOC. We expect to provide a new treatment strategy to prevent the growth of this neoplasm. PMID- 29443743 TI - Circulating miR-146a/b correlates with inflammatory cytokines in COPD and could predict the risk of acute exacerbation COPD. AB - The aim of this study was to investigate the predicting value of miR-146a/b for acute exacerbation chronic obstructive pulmonary disease (AECOPD) and COPD, and to explore their associations with inflammatory cytokines in AECOPD and stable COPD patients.One hundred six AECOPD, 122 stable COPD patients, and 110 health volunteers with age and sex matched to total COPD patients (AECOPD and stable COPD) were enrolled. Blood samples were collected from all participants. Relative expression of miR-146a/b was determined by real-time polymerase chain reaction. Tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta), interleukin-6 (IL-6), interleukin-8 (IL-8), leukotriene B4 (LTB-4) expression in serum from AECOPD and stable COPD patients were assessed using commercial ELISA kit.Serum levels of miR-146a and miR-146b were down regulated in AECOPD patients compared with stable COPD patients and HCs. miR-146a and miR-146b are of good values for predicting the risk of AECOPD in HCs with AUC of 0.702 and 0.715. Additionally, miR-146a and miR-146b could distinguish AECOPD from stable COPD patients with AUC of 0.670 and 0.643. In AECOPD patients, levels of miR-146a in AECOPD patients were negatively associated with TNF-alpha, IL-6, IL-8, and LTE-4 expression. In stable COPD patients, miR-146a expressions were negatively correlated with TNF-alpha, IL-1beta, IL-6, IL-8, and LTE-4 levels. And, the expressions of miR-146b in AECOPD patients were negatively associated with IL 1beta and LTB-4 expression. While in stable COPD patients, miR-146b expressions were only negatively correlated with TNF-alpha level.In conclusion, miR-146a and miR-146b were negatively correlated with inflammatory cytokines, and could be promising biomarkers for predicting the risk of AECOPD in stable COPD patients and healthy individuals. PMID- 29443744 TI - Serum levels of vitamin A and 25-hydroxyvitamin D3 (25OHD3) as reflectors of pulmonary function and quality of life (QOL) in children with stable asthma: A case-control study. AB - BACKGROUND: This study aims to explore the relationship between serum vitamin A and 25-hydroxyvitamin D3 (25OHD3) levels with pulmonary function and quality of life (QOL) in children with stable asthma. METHODS: A total of 117 cases of children with stable asthma were assigned into the case group and 129 healthy children underwent physical examination during the same period into the control group. Electrochemiluminescence was employed to determine serum vitamin A and 25OHD3 levels. The children with stable asthma were further divided into the mild, moderate, and severe groups according to their degree of asthma. A pulmonary function meter was used to assess the pulmonary function indexes: percentage of forced expiratory volume in 1 sec/predictive value (FEV1%pred), forced vital capacity (FVC), forced expiratory volume in 1 sec/forced vital capacity (FEV1/FVC), peak expiratory flow (PEF), and maximal voluntary ventilation (MVV). The children's quality (QOL) of life with asthma was evaluated by their activities of daily living (ADLs) and Medical Research Council (MRC) scores. Pearson correlation analysis was applied to analyze the correlations of serum vitamin A and 25OHD3 levels with FEV1%pred, FVC, FEV1/FVC, PEF, MVV, ADL, and MRC. RESULTS: Serum vitamin A and 25OHD3 levels were lower in children with stable asthma than those who were in the control group (P < .05). The severe group showed the lowest FEV1%pred, FVC, FEV1/FVC, PEF, MVV, and ADL scores, and the highest MRC score compared to the mild and moderate groups (all P < .05). Serum vitamin A and 25OHD3 levels were positively correlated with pulmonary function and ADL score in children with stable asthma, while serum vitamin A and 25OHD3 levels were negatively correlated with MRC score (all P < .05). In the case group, serum vitamin A and 25OHD3 levels were positively correlated with serum calcium and phosphorus levels (all P < .05). CONCLUSION: These findings indicate that increased serum vitamin A and 25OHD3 levels reflect good pulmonary function and good QOL in children with stable asthma. PMID- 29443745 TI - Laparoscopic left lateral hepatic sectionectomy was expected to be the standard for the treatment of left hepatic lobe lesions: A meta-analysis. AB - BACKGROUND: Laparoscopic left lateral hepatic sectionectomy (LLLHS) has been widely accepted because of the benefits of minimally invasive surgery. We aimed to assess the benefits and drawbacks of left lateral sectionectomy (of segments II/III) compared with laparoscopic and open approaches. METHODS: Relevant literature was searched using the PubMed, Embase, Cochrane, and Ovid Medline databases. We calculated odds ratios or mean differences with 95% confidence intervals (CIs) for fixed-effects and random-effects models. RESULTS: The meta analysis included 14 trials involving 685 patients. There were no statistically significant differences between LLLHS and open LLHS (OLLHS) regarding analgesia (P = .31), pedicle clamping (P = .70), operative time (P = .54), hospital expenses (P = .64), postoperative alanine aminotransferase levels (P = .57), resection margin (95% CI -3.02-4.28; P = .73), or tumor recurrence (95% CI 0.51 3.05; P = .62). However, the LLLHS group showed significantly better results regarding blood transfusion (95% CI 0.14-0.73; P = .007), blood loss (95% CI 140.95 to -67.23; P <.001), total morbidity (95% CI 0.24-0.56; P <.01), and hospital stay (95% CI -3.84 to -2.31; P <.001) than the OLLHS group. CONCLUSION: LLLHS has an advantage in the hospital stay, blood loss, and total morbidity. It is an ideal method for LLHS surgery. PMID- 29443746 TI - Platelet count to spleen thickness ratio is related to histologic severity of primary biliary cholangitis. AB - The aim of this study was to evaluate the ability of noninvasive markers to identify the histological severity of primary biliary cholangitis (PBC).Fifty eight treatment-naive PBC patients who had undergone liver biopsy were enrolled in our study. The patients' histological stages were based on the classifications of Ludwig and Scheuer. Aspartate aminotransferase-to-platelet ratio index (APRI), fibrosis index based on the 4 factors (FIB-4), red blood cell distribution width to platelet ratio (RPR), and platelet count to spleen thickness (PC/ST) ratio were calculated. Using the area under the receiver operating characteristic curve (AUROC) to evaluate the accuracy of different markers for predicting the histological severity.Among the 58 treatment-naive PBC patients, the patients of Scheuer stage I/II/III/IV were 17/25/11/5, respectively. PC/ST ratio (AUROC = 0.807) was superior to RPR (AUROC = 0.717), APRI (AUROC = 0.726), FIB-4 (AUROC = 0.722), and mean platelet volume (MPV) (AUROC = 0.671) in discriminating between stage I and stage >=II. The AUROC of PC/ST ratio, RPR, APRI, FIB-4, and MPV were 0.939, 0.872, 0.816, 0.831 and 0.572, respectively, for Scheuer stage >=III; 0.968, 0.795, 0.744, and 0.723, respectively for stage IV. The sensitivity and specificity of PC/ST ratio were 73.4%,79.1%; 81%,100%;88.7%,100% for detection of Scheuer stage >= II, Scheuer stage >= III and Scheuer stage IV, respectively.Our study findings indicated that compared with previous noninvasive test PRP, APRI, FIB-4 and MPV, PC/ST ratio shows the most accurate for distinguish the histologic severity of PBC patients. PMID- 29443747 TI - Supraglottoplasty in neonates and infants: A radiofrequency ablation approach. AB - BACKGROUND: Supraglottoplasty is the mainstay of surgical treatment for laryngomalacia. A novel supraglottoplasty surgical technique is needed to achieve better efficacy. The purpose of this study was to introduce modified microscopic radiofrequency ablation supraglottoplasty (MMRAS) for the treatment of congenital laryngomalacia and to evaluate the outcome and effectiveness of this novel approach. METHODS: Seventeen children with severe laryngomalacia who underwent MMRAS were studied retrospectively. Supraglottoplasty of type III laryngomalacia was different from classical method. All the patients were kept intubated for 5 days after surgery to achieve a better epiglottal position and to avoid reconglutination of aryepiglottic folds. The patients' demographic information, symptoms, comorbidities, type of laryngomalacia, synchronous airway lesions and final outcomes were examined. RESULTS: The median age at the time of surgery was 3.36 months (3 months 10 days). Operative indications included feeding difficulties, noisy breathing or respiratory distress (or both), and sleep related symptoms. The MMRAS success rate was 82.4%. Most patients were extubated successfully on postoperative day 5. The major postoperative complication was pulmonary infection which occurred in 3 cases (17.6%) and required anti-infective therapy. No perioperative deaths and no long-term complications occurred. Failures were observed in 3 (17.6%) of 17 cases, 2 patients presented with a neurological disease and required tracheostomy, 1 patient relapsed because of postoperative adhesions and later underwent revision supraglottoplasty. CONCLUSIONS: From these results, we conclude that MMRAS is an effective and safe treatment for symptomatic laryngomalacia and has the potential to provide better breathing, feeding, and sleeping outcomes in children with severe laryngomalacia. Postoperative intubation for 5 days may result in better therapeutic outcomes. Multicenter cooperative studies of comparison between MMRAS and conventional approaches would lend further evidence-based support for this surgical method. PMID- 29443748 TI - Ultrasound combined with fine needle aspiration cytology for the assessment of axillary lymph nodes in patients with early stage breast cancer. AB - This study aimed to explore the clinical usefulness of ultrasound-guided fine needle aspiration cytology (USG-FNAC) for the evaluation of axillary lymph nodes in patients with early stage breast cancer (BC) among the Chinese Han female population.Around 124 patients with early stage BC were included in this retrospective study. All patients underwent USG-FNAC (group A). Patients with proven metastasis also underwent axillary lymph node dissection (ALND) (group B). In addition, sentinel lymph node biopsy (SLNB) was performed 2 to 5 hours prior to the surgery.The sensitivity, specificity, accuracy, and positive predictive value (PPV) of axillary ultrasound were 75.0%, 75.0%, 75.0%, and 82.6%, respectively, while for USG-FNAC, they were 80.8%, 100.0%, 88.7%, and 100.0%, respectively. Significant differences were found in specificity, accuracy, and PPV between the 2 procedures (P < .05).The results of this study demonstrated that USG-FNAC was effective for selecting patients with early stage BC using ALND or SLNB among the Chinese Han female population. PMID- 29443749 TI - Usefulness of the maximum standardized uptake value for the diagnosis and staging of patients with cervical cancer undergoing positron emission tomography/computed tomography. AB - Cervical cancer recently has become more common among younger women in Japan. Diagnosing early-stage cancer is straightforward using cervical cytodiagnosis and histological diagnosis. However, postmenopausal endophytic cervical cancer and skip lesions in cervical adenocarcinoma are difficult to detect. We compared the maximum standardized uptake value (SUVmax) of 18F-fluorodeoxy-glucose positron emission tomography/computed tomography (PET/CT) for primary staging of cervical cancer and evaluated the relationship of the imaging findings to prognosis.This was a retrospective study of 38 patients with cervical cancer who underwent PET/CT. Patients were grouped according to disease stage, and the mean SUVmax, overall survival, and progression-free survival (PFS) were evaluated.The mean SUVmax was significantly different between patients with stage <=I and >=II diseases among those with squamous (P > .001) and glandular (P = .023) lesions. With an SUVmax of receiver operating characteristic curves as the optimal cutoff value, the log-rank test for PFS revealed a statistically significant difference between the 2 disease stages (P = .020 and P = .016, respectively).SUVmax is useful to differentiate between stage <=I and >=II cervical cancer. SUVmax may be useful for the prognostic evaluation of disease recurrence in patients with cervical cancer. PMID- 29443750 TI - Effect and safety of roflumilast for chronic obstructive pulmonary disease in Chinese patients. AB - BACKGROUND: This trial aimed to evaluate the efficacy and safety of roflumilast for treating Chinese patients with chronic obstructive pulmonary disease (COPD). METHODS: A total of 120 patients with COPD were recruited and were randomly divided into 2 groups (an intervention group and a placebo group) at a 1:1 ratio. Patients received either roflumilast or placebo 500 MUg once daily for a total of 12 months. The primary outcome was lung function, measured by the change from baseline of forced expiratory volume in 1 second (FEV1), FVC = forced vital capacity (FVC), and FEF25-75%. The secondary outcome measurements included the quality of life, measured with the St. George's Respiratory Questionnaire (SGRQ). All outcomes were measured at the end of 12-month treatment and 3-month follow-up after the treatment. In addition, adverse events (AEs) were also recorded during the treatment period. RESULTS: FEV1, FVC, FEF25-75%, and SGRQ were significantly better in the intervention group than those in the placebo group at the end of 12 month treatment and 3-month follow up after treatment. Moreover, AEs were much higher with roflumilast than placebo in this study. CONCLUSIONS: The findings suggest that roflumilast has promising effect to improve lung function in Chinese population with COPD.

AB - RATIONALE: Schwannomas of gastrointestinal tracts are rare and difficult to detect preoperatively because of negative results of endoscopic and imaging examinations. Here, we reported a case of rectal schwannoma, which was diagnosed by immunohistochemical staining after laparoscopic protectomy. PATIENT CONCERNS: A 61-year-old woman complained of a 1-month history of difficulty in defecation and irregularly abdominal discomfort during her physical checkup in our hospital. DIAGNOSES: Immunohistochemical staining results after laparoscopic protectomy revealed a strong positive reaction for S-100 protein. Therefore, rectal schwannoma was confirmed. INTERVENTIONS: Treatment with laparoscopic protectomy was given. OUTCOMES: Symptoms resolved completely after 12 days of the surgery, and was regular followed-up in outpatient clinic. LESSONS: Schwannomas are difficult to identify preoperatively, and immunohistochemical staining for S-100 protein is an effective method to diagnose it. PMID- 29443752 TI - The first case report of Enterococcus gallinarum meningitis in neonate: A literature review. AB - RATIONALE: Enterococcus gallinarum meningitis (EGM) is rarely found in normal adults and even rarer in children. To our knowledge, EGM in neonate has not been reported previously. PATIENTS CONCERNS: Here we reported the first case of EGM in neonate. Prolonged fever was the only manifestation for the case after admission. DIAGNOSES: Cerebrospinal fluid cultures showed that the isolate was Enterococcus gallinarum and sensitive to linezolid. INTERVENTIONS: Ceftriaxone, beta lactam type, and vancomycin were used respectively, but not effective. OUTCOMES: The temperature went down to normal after linezolid was used and the baby was discharged in good condition in the end. LESSONS: This case indicated that EGM could also occur in neonate and fever could be the only obvious manifestation. Thus, the effective antibiotics and adequate duration are very important and linezolid is a potential good choice, especially for vancomycin-resistant patients. PMID- 29443753 TI - Intense 18F-FDG activity in aortoiliac bypass graft mimicking infection: A case report. AB - RATIONALE: F-fluorodeoxyglucose (F-FDG) positron emission tomography/computed tomography (PET/CT) has the potential to become an important imaging tool for the diagnosis of suspected aortoiliac bypass graft infection (AGI). PATIENT CONCERNS: A 76-year-old man presented with incidental findings of intense F-FDG activity in previous operation site of aortobiiliac bypass graft in the initial staging of small cell lung cancer (SCLC). DIAGNOSES: Based on F-FDG PET/CT examination, preliminary differential diagnosis was AGI. INTERVENTIONS: We performed laboratory tests and Galliun-citrate (Ga) single photon emission computed tomography/computed tomography (SPECT/CT). OUTCOMES: He had no constitutional symptoms and abnormal laboratory test results suggesting AGI. CT scan of the abdomen and pelvis showed no abnormal findings. Also, Ga planar scintigraphy and SPECT/CT imaging of the abdomen and pelvis failed to show abnormal Ga uptake in the same site of aortobiiliac bypass graft with F-FDG uptake. LESSONS: We present a case with postoperative inflammatory aortobiiliac bypass graft which was misdiagnosed as AGI based on intense F-FDG activity seen at PET/CT imaging. PMID- 29443754 TI - Multiple extra-articular synovial cysts accompanied by rheumatoid arthritis in the bilateral elbow joints: A case report. AB - RATIONALE: Synovial cysts are well known in rheumatoid arthritis (RA), and most common in the popliteal fossa. They may produce lots of local symptoms and complaints, which may present initially as an unrelated clinical condition. Few studies have reported multiple extra-articular synovial cysts (MESCs) in the RA patients. Early diagnosis is crucial for patient treatment. PATIENT CONCERNS: A 50-year-old man without any special clinical histories found a soya bean size bump at the left elbow medially, then multiple lumps were found at bilateral elbows and gradually increasing. No pain, no activity, no redness, and swelling. Magnetic resonance imaging (MRI) showed multiple cystic lesions in the bursa and surrounding soft tissue of bilateral elbow joints. In addition, the elbow joint bursa was swollen and the synovial membrane was significantly thickened. DIAGNOSES: The man was diagnosed as RA with multiple extra-articular synovial cysts formation. INTERVENTIONS: The patient was performed tylectomy of the right elbow. Other lumps were punctured and injected with compound betamethasone injection. OUTCOMES: The bumps were reduced in size and the swelling relieved, and the patient was sent to the department of rheumatology and immunology for further treatment. LESSONS: In this case, it is difficult for the diagnosis of RA because of no relative histories and simultaneously multiple cystic lesions in multiple joints. Imaging examinations can show the characteristics of such kind of disease and be very helpful for the diagnosis and differentiate diagnosis. PMID- 29443755 TI - Argininemia as a cause of severe chronic stunting and partial growth hormone deficiency (PGHD): A case report. AB - RATIONALE: Argininemia is an autosomal recessive inherited disorder of the urea cycle. Because of its atypical symptoms in early age, diagnosis can be delayed until the typical chronic manifestations - including spastic diplegia, deterioration in cognitive function, and epilepsy - appear in later childhood. PATIENT CONCERNS: A Chinese boy initially presented with severe stunting and partial growth hormone deficiency (PGHD) at 3 years old and was initially treated with growth hormone replacement therapy. Seven years later (at 10 years old), he presented with spastic diplegia, cognitive function lesions, epilepsy, and peripheral neuropathy. DIAGNOSES: Ultimately, the patient was diagnosed with argininemia with homozygous mutation (c.32T>C) of the ARG1 gene at 10 years old. Blood tests showed mildly elevated blood ammonia and creatine kinase, and persistently elevated bilirubin. INTERVENTIONS: Protein intake was limited to 0.8 g/kg/day, citrulline (150-200 mg [kg d]) was prescribed. OUTCOMES: The patient's mental state and vomiting had improved after 3 months treatment. At 10 years and 9 month old, his height and weight had reached 121cm and 22kg, respectively, but his spastic diplegia symptoms had not improved. LESSONS: This case demonstrates that stunting and PGHD that does not respond to growth hormone replacement therapy might hint at inborn errors of metabolism (IEM). IEM should also be considered in patients with persistently elevated bilirubin with or without abnormal liver transaminase, as well as elevated blood ammonia and creatine kinase, in the absence of hepatic disease. PMID- 29443756 TI - Ulcerative colitis followed by the development of typical intestinal Behcet disease: A case report. AB - RATIONALE: Intestinal Behcet disease (intestinal BD) and inflammatory bowel disease (IBD) share a lot of characteristics, including genetic background, clinical manifestations, and therapeutic strategies, especially the extraintestinal manifestations, such as oral ulcers, arthralgia, eye lesions, skin lesions, etc, but the coexistence of these 2 diseases are uncommon. Behcet disease with gastrointestinal involvement in ulcerative colitis (UC) patient has been reported in just 1 previous case report, but, which can not be diagnosed as definite intestinal BD based on Korean novel diagnositic criteria due to lacking the typical ileocecal ulcer. PATIENT CONCERNS: We present a 23-year-old woman with ulcerative disease who developed typical intestinal BD, which is the first case report of patient with coexisting UC and typical intestinal BD. DIAGNOSES: This patient was diagnosed as coexistence of intestinal BD and UC base on the clinical manifestations, extra intestinal manifestations and typical colonoscopic findings. INTERVENTIONS: Steroid and methotrexate were administered. OUTCOMES: This patient achieved clinical remission and mucosal healing. LESSONS: Coexistence of intestinal BD and UC is uncommon, and the combination with steroid, methotrexate, and 5-aminosalicylic acids is an effective therapy. PMID- 29443757 TI - Various surgical techniques to create an aesthetic appearance at the donor site of anterolateral thigh free flaps based on the oblique branch: Twenty-one clinical case reports. AB - RATIONALE: Reducing the morbidity associated with anterolateral thigh (ALT) donor sites by performing aesthetic restoration has become a popular research topic. Various surgical techniques have been developed allowing for direct closure of the donor site. However, closure techniques for ALT donor sites based on the oblique branch have not been systematically reported. PATIENT CONCERNS: Data from 21 patients (18 males, 3 females) undergoing operative reconstruction with an ALT free flap between January 2016 and December 2016. The mean age of the participants was 42 years (range, 18-60 years). DIAGNOSES: The soft-tissue defects resulted from a traffic accident in 9 patients, a fall injury in 7 patients, a machinery injury in 3 patients, an electrical injury in 1 patient, and a burn scar in 1 patient. The wound areas ranged from 6 * 3.5 to 28 cm * 10 cm. INTERVENTIONS: Several surgical techniques, including the split skin paddle technique and utilization of an adjacent perforator flap or an ipsilateral groin flap, were utilized to facilitate direct closure of the ALT flap donor site. OUTCOMES: Of the 21 patients included in the study, the donor sites were directly sutured in 14 patients (8 of which required a split skin paddle technique). Four patients required an adjacent perforator flap, and 3 patients received an ipsilateral groin flap. The size of the adjacent perforator flaps ranged from 15 * 5 to 17 * 6 cm. The groin flaps ranged from 18 * 6 to 28 * 6 cm. All the flaps had excellent appearance and texture. A linear scar in the donor area was not conspicuous and achieved an aesthetic appearance. LESSONS: The ALT flap donor site based on the oblique branch pedicle can be directly closed without skin grafts through the use of several surgical techniques. PMID- 29443758 TI - A novel arthroscopic all-inside suture technique using the Fast-Fix 360 system for repairing horizontal meniscal tears in young athletes: 3 case reports. AB - RATIONALE: Considering the risk of osteoarthritis following resection of a horizontally torn meniscus of the knee, repairing and preserving the meniscus as much as possible is preferred. We report 3 cases of restoration of horizontally torn menisci using a novel arthroscopic method we have called "all-inside interleaf vertical suture" that afforded preservation. PATIENT CONCERNS: The 3 patients (aged 14, 17, and 21 years) had knee pain through sports activity. DIAGNOSES: All patients had horizontal tears in the posteromedial part of the meniscus. INTERVENTIONS: The method uses Fast-Fix, whereby a first anchor is inserted from the tibial surface of the tear's superior leaflet and a second anchor is inserted from the femoral surface of the tear's inferior leaflet, and the 2 leaflets are closed using vertical suture. In all cases, the suture knots were embedded between the superior leaflet and inferior leaflet, avoiding contact with the articular cartilage, and superior leaflet and inferior leaflet crimping was good. OUTCOMES: All 3 were able to resume competing in sport and >= 1 year after surgery they had no pain and their postoperative mean Lysholm scores were 99.7. There were no complications or recurrence. On magnetic resonance imaging, the signal intensity of all the horizontal tears was high before surgery but low after surgery, suggesting that the repaired tear was healing. LESSONS: The all inside interleaf vertical suture procedure is a new surgical technique that can repair posteromedial horizontal meniscal tears of the knee of young people by easy crimping of the superior and inferior leaflets without the suture knots causing complications. PMID- 29443759 TI - A traumatic hepatic artery pseudoaneurysm and arterioportal fistula, with severe diarrhea as the first symptom: A case report and review of the literature. AB - RATIONALE: Hepaticarterioportal fistula (APF) is a rare cause of portal hypertension and gastrointestinal hemorrhage, and presents as abnormal communication between the hepatic artery and portal vein. Percutaneous liver biopsy is a main iatrogenic cause of AFP. However, non-iatrogenic, abdominal, trauma-related APF is rarely reported. PATIENT CONCERNS: A 29-year-old man presenting with severe, watery diarrhea was transferred to our hospital, and his condition was suspected to be acute gastroenteritis because he ate expired food and suffered a penetrating abdominal stab wound 5 years ago. After admission, the patient suffered from hematemesis, hematochezia, ascites, anuria, and kidney failure, and he developed shock. DIAGNOSES: The patient was finally diagnosed as a traumatic hepatic artery pseudoaneurysm and APF. INTERVENTIONS: This patient was treated with emergency transarterial embolization using coils. Since a secondary feeding vessel was exposed after the first embolization of the main feeding artery, a less-selective embolization was performed again. OUTCOMES: During the 6-month follow-up period, the patient remained asymptomatic. LESSONS: A penetrating abdominal stab wound is a rare cause of hepatic APFs, and occasionally leads to portal hypertension, the medical history and physical examination are the most important cornerstones of clinical diagnosis. Interventional radiology is essential for the diagnosis and treatment of an APF. PMID- 29443760 TI - Resection of benign side-branch intraductal papillary mucinous neoplasm of the pancreas-is long term follow-up indicated?: A case report and review of the literature. AB - RATIONALE: Intraductal papillary mucinous neoplasms of the pancreas (IPMNs) are benign cystic tumors with a relevant risk of malignant transformation over time. Currently, follow-up after surgical resection of benign IPMNs remains controversial. PATIENT CONCERNS: This is a case report of a 68-year-old male who underwent pancreatic head resection for a multicystic side-branch IPMN with low grade epithelial dysplasia in March 2009 at the Katharinenhospital Stuttgart, Germany. DIAGNOSES: During postoperative follow-up, a new solid, slightly hypodense lesion in the tail of the pancreas measuring 2.4 cm in diameter was diagnosed in July 2016. Preoperative staging revealed no signs of distant metastasis. INTERVENTION: Subsequently, the patient underwent pancreatic tail resection including splenectomy. Histology revealed IPMN-associated adenocarcinoma of the pancreas pT3, pN1 (2/24), M0, R0. OUTCOMES: Patients with IPMN bare a relatively high overall risk of developing pancreatic cancer. The 5 year incidence has been described to be as high as 6.9%. The current Consensus Guidelines therefore recommend a structural life-time follow-up. In contrast, in 2015 the American Gastroenterological Association (AGA) explicitly states that follow-up is not recommended for resected benign IPMN. Currently, a general and international consensus is lacking. LESSONS: The presented case demonstrates that even more than 5 years following resection of benign IPMN, pancreatic cancer can occur in a separate location of the pancreatic gland. We believe that IPMNs can be considered as indicator lesions for pancreatic cancer. Patients with resected side-branch IPMN should therefore undergo long term follow-up. PMID- 29443761 TI - Haemolytic-uremic syndrome due to infection with adenovirus: A case report and literature review. AB - RATIONALE: Haemolytic-uremic syndrome is a rare but serious complication of bacterial and viral infections, which is characterized by the triad of: acute renal failure, microangiopathic haemolytic anemia and thrombocytopenia, sometimes severe, requiring peritoneal dialysis. In Europe, hemolytic-uremic syndrome (HUS) in paediatric pathology is primarily caused by Shiga toxin-producing Escherichia coli (STEC) O157, followed by O26. Beside these etiologies, there are other bacterial and viral infections, and also noninfectious ones that have been associated to lead to HUS as well: in the progression of neoplasia, medication related, post-transplantation, during pregnancy or associated with the antiphospholipid syndrome, systemic lupus erythematosus or family causes with autosomal dominant or recessive inheritance. In terms of pathogenesis, HUS is the result of endothelial injury, most commonly being a result of the action of Shiga toxin. The unfavorable prognosis factors being represented by the age of more than 5 years old, different etiologies from STEC, persistent oligoanuria, central nervous system and glomerular impairment, the association of fever with leukocytosis. HUS is responsible for 7% of cases of hypertension in infants, and an important cause of significant kidney damage in adults. PATIENT CONCERNS: We present one case of HUS caused by adenovirus in a boy of 1 year and 7 months old with severe evolution, which required peritoneal dialysis. DIAGNOSE: Stool sample repeated examination for adenovirus antigen was positive in 2 samples. INTERVENTION: During hospitalization, the patient required 8 peritoneal dialysis sessions. OUTCOME: The renal function was corrected on discharge, the patient required cardiovascular monitoring 1 month after discharge. LESSON: Although the most common cause that leads to HUS remains STEC, other etiologies like viral ones that may be responsible for severe enteric infection with progression into HUS should not be neglected. PMID- 29443762 TI - Incidence and risk factors for surgical site infection after open reduction and internal fixation of ankle fracture: A retrospective multicenter study. AB - : Information on surgical site infection (SSI) after surgical treatment of ankle fracture is limited and remains controversial. The purpose of the present study was to determine the incidence and risk factors for SSI after open reduction and internal fixation (ORIF) of ankle fracture. Patients who underwent ORIF for ankle fracture at 3 centers between January 2015 and December 2016 were included. The potential risk factors for SSI included demographic variables, including age, sex, body mass index (BMI), hypertension, diabetes mellitus, heart disease, smoking, and excessive alcohol intake; blood test variables including preoperative white blood cell count, neutrophil count, red blood cell count, hemoglobin, total protein, albumin and globulin; injury- and surgery-related variables, including duration of operation (minutes), intraoperative blood loss, surgeon level, fracture site, accompanied dislocation, use of a drainage tube, and antibiotic use. Factors related with SSI occurrence were investigated by univariate analysis, and then by multivariate analysis. During hospitalization, 4.37% (66/1511) of patients developed SSI, which was deep in 1.32% (20/1510) and superficial in 3.05% (46/1510). The most common causative agent was polymicrobial (causing approximately half of all SSIs), followed by methicillin-resistant Staphylococcus aureus (MRSA). Multivariate analysis revealed that the significant risk factors for SSI occurrence were open injury, advanced age, incision cleanliness II - IV, high-energy injury, more experienced surgeon level, greater BMI, chronic heart disease, history of allergy, and preoperative neutrophil count > 75%. Preoperative preventative measures should be taken in patients with these conditions to lower the incidence of SSI after ORIF of ankle fracture. LEVEL OF EVIDENCE: Level III - Retrospective Comparative Study. PMID- 29443763 TI - Epibulbar complex cartilaginous choristoma: A distinctive clinicopathological case series and literature review. AB - To newly describe the clinical and histopathological characteristics of epibulbar complex cartilaginous choristoma incidentally observed in a series of pterygium excision patients.Noncomparative case series with chart review of 8 patients.During a 4-year period, we identified 8 cases of conventional unilateral nasal subpterygial cartilaginous choristoma in 1799 pterygium patients and analyzed their clinicopathological features. The incidence rate of this entity is 0.44% in pterygium patients. All of the cartilaginous choristomas were buried deep in the caruncle, covered by the pterygium, and embedded in tenon facia tissue. Its clinicopathological characteristics include hyaline cartilaginous tissue that is surrounded by fibrous connective tissue and smooth muscle bundles. S-100 protein-staining specifically revealed chondrocytes embedded within chondroid matrix.Epibulbar complex cartilaginous choristoma covered by pterygia and predominantly observed in the older population is rare. The lesions were buried deep in the caruncle, covered by the pterygium and embedded in tenon fascia tissue. These findings are inconsistent with those in previous reports. PMID- 29443764 TI - Assessment of interchangeability rate between 2 methods of measurements: An example with a cardiac output comparison study. AB - The Bland-Altman (BA) and percentage error (PE) methods have been previously described to assess the agreement between 2 methods of medical or laboratory measurements. This type of approach raises several problems: the BA methodology constitutes a subjective approach to interchangeability, whereas the PE approach does not take into account the distribution of values over a range. We describe a new methodology that defines an interchangeability rate between 2 methods of measurement and cutoff values that determine the range of interchangeable values. We used a simulated data and a previously published data set to demonstrate the concept of the method. The interchangeability rate of 5 different cardiac output (CO) pulse contour techniques (Wesseling method, LiDCO, PiCCO, Hemac method, and Modelflow) was calculated, in comparison with the reference pulmonary artery thermodilution CO using our new method. In our example, Modelflow with a good interchangeability rate of 93% and a cutoff value of 4.8 L min, was found to be interchangeable with the thermodilution method for >95% of measurements. Modelflow had a higher interchangeability rate compared to Hemac (93% vs 86%; P = .022) or other monitors (Wesseling cZ = 76%, LiDCO = 73%, and PiCCO = 62%; P < .0001). Simulated data and reanalysis of a data set comparing 5 CO monitors against thermodilution CO showed that, depending on the repeatability of the reference method, the interchangeability rate combined with a cutoff value could be used to define the range of values over which interchangeability remains acceptable. PMID- 29443765 TI - Clinical significance of superior articular process as a reference point for free hand pedicle screw insertion in thoracic spine. AB - The trajectory of the pedicle screw perpendicular to the SAP (superior articular process) is consistent with the universal trajectory presented in the previous study of the entry point using computed tomography. The ideal entry point and trajectory of pedicle screw insertion have been a matter of considerable debate. We attempted to find the relationship between SAP and entry point and trajectory of the pedicle screw.Thoracic spine CT (computed tomography) scans of 9 volunteers were studied. A safe zone for the trajectory of the screw in the axial (MarginAx) and sagittal (MarginSag) was defined as the zone between lines perpendicular to the SAP along the medial and lateral cortex of the pedicle in the axial section, and the superior and inferior cortex in the sagittal section without violation of the pedicle walls. The midline of MarginAx and MarginSag was defined as the safe entry point of the trajectory in the axial and sagittal planes (TrajectoryAx and TrajectorySag), respectively.MarginAx and MarginSag were 4.14 +/- 0.99 and 9.03 +/- 2.01 mm, respectively. There was a statistically significant difference in TrajectoryAx between the upper and middle, and between the upper and lower (P = .0076 in both cases), but not between the middle and lower thoracic spine (P = .066). TrajectorySag was within 1 mm at the levels of T4, T8, T11 vertebrae and at 0 mm at the other levels. Thus, the midpoint of MarginSag was within 1 mm from the SAP base.There was a constant angular relationship with the SAP and the pedicle axis; the line perpendicular to the SAP can act as a trajectory. Therefore, we suggest that the SAP might be the only accurate and safe reference for pedicle screw insertion in the thoracic spine perpendicular to the SAP using freehand technique. PMID- 29443766 TI - Meta-analysis study comparing percutaneous coronary intervention/drug eluting stent versus coronary artery bypass surgery of unprotected left main coronary artery disease: Clinical outcomes during short-term versus long-term (> 1 year) follow-up. AB - BACKGROUND: Results on the safety and long-term efficacy of drug-eluting stent placement in unprotected left main coronary artery disease (ULMCAD) compared with those of coronary artery bypass surgery (CABG) remain inconsistent across randomized clinical trials and recent meta-analysis studies. We aimed to compare the clinical outcomes and safety over short- and long-term follow-ups by conducting a meta-analysis of large pooled data from randomized controlled trials and up-to-date observational studies. METHODS: A systematic review of PubMed, Google Scholar, Medline, and reference lists of related articles was performed for studies conducted in the drug-eluting stent era, to compare percutaneous coronary intervention (PCI) with CABG in ULMCAD. The primary outcome was major adverse cardiovascular and cerebrovascular events (MACCE), myocardial infarction (MI), stroke, all-cause mortality, and revascularization after at least 1-year follow-up. In-hospital and 30-day clinical outcomes were considered secondary outcomes. Furthermore, a subgroup analysis of studies with >=5 years follow-up was performed to test the sustainability of clinical outcomes. RESULTS: A total of 29 studies were extracted with 21,832 patients (10,424 in PCI vs 11,408 in CABG). Pooled analysis demonstrated remarkable differences in long-term follow-up (>=1 year) MACCE (odds ratio [OR] 1.42, 95% CI 1.27-1.59), P < .00001), repeat revascularization (OR 3.00, 95% CI 2.41-3.73, P < .00001), and MI (OR 1.32, 95% CI 1.14-1.53, P = .0002), favoring CABG over PCI. However, stroke risk was significantly lower in the PCI group. Subgroup analysis of studies with >=5 years follow-up showed similar outcomes except for the noninferiority outcome of MACCE in the PCI arm. However, the PCI group proved good safety profile after a minimum of 30-day follow-up with lower MACCE outcome. CONCLUSION: PCI for ULMCAD can be applied with attentiveness in carefully selected patients. MI and the need for revascularization remain drawbacks and areas of concern among previous studies. Nonetheless, it has been proven safe during short-term follow-up. PMID- 29443767 TI - Effect of oxycodone hydrochloride combined with flurbiprofen axetil for intravenous patient-controlled analgesia in lower abdominal patients: A randomized trial. AB - BACKGROUND: Problems like postoperative pain are still common phenomena after general anesthesia. Oxycodone hydrochloride is a semisynthetic opioid with a safe and excellent therapeutic effect on visceral pain. Flurbiprofen axetil has the efficacy of targeted analgesia. We hypothesize that different doses of oxycodone hydrochloride combined with flurbiprofen axetil would generate great results on postoperative intravenous analgesia in lower abdominal patients. METHODS: In the clinical trial, 90 American Society of Anesthesiologists I or II patients scheduled for elective general anesthesia were randomly divided into 3 groups, 30 cases in each group. Group I: oxycodone hydrochloride 0.5 mg/kg + flurbiprofen axetil 150 mg, group II: oxycodone hydrochloride 0.75 mg/kg + flurbiprofen axetil 150 mg, group III: oxycodone hydrochloride 1.0 mg/kg + flurbiprofen axetil 150 mg. Dilute them with 0.9% saline to 150 mL, respectively, with the background dose of 2 mL/h, patient-controlled analgesia 2 mL per time, with an interval of 10 min, and the loading dose of 0.1 mL/kg. Record the preoperative situation, 24 h (T0) before surgery, postoperative situation, 1 h (T1), 4 h (T2), 8 h (T3), 12 h (T4), 24 h (T5), 48 h (T6), 72 h (T7) after the surgery, including the mean arterial pressure, heart rate, saturation of pulse oximetry, static and dynamic pain rating (NRS) and Ramsay sedation score, effective pressing and total pressing ratio (referred to as the pressing ratio), patient satisfaction, and occurrence of adverse reactions. RESULTS: There was no significant statistic difference in mean arterial blood pressure, heart rate, arterial oxygen saturation, and adverse reactions among the 2 groups at each time point (P > .05). Compared with group I, the static NRS rating in group II and group III were significantly lower than that in group I (P < .05) from T1 to T5. The dynamic NRS rating of group II from T1 to T4 and that of group III from T1 to T5 were significantly lower (P < .05). The effective pressing and total pressing ratio was significantly higher (P < .05). There was no significant statistic difference between group II and group III in NRS rating and the effective pressing and total pressing ratio (P > .05). Compared with group III, the Ramsay sedation scores of group I and group II were significantly lower from T1 to T4 (P < .05). CONCLUSION: The dose of 0.75 mg/kg oxycodone hydrochloride combined with flurbiprofen axetil can provide safe and effective postoperative analgesia for lower abdominal patients, with fewer adverse reactions. PMID- 29443769 TI - Establishment of Comprehensive Indicators in TCM Pectoral-qi Case Report Based on Experts Diagnosis and Self-test Technology. AB - RATIONALE: To establish TCM Pectoral-qi comprehensive indicators and highlight the inner structure among different variables in an objective way, the article uses Partial Least Square Second-order Latent Variable Model (PLS-SLVM) and accomplishes 3 different comprehensive indicators based on both experts diagnosis and self-test data. SLVM includes a measurement model that defines the relationship between observed variables and latent variables and a structure model that imputes relationships between latent variables. The article focuses on PLS as the estimation method. Without normal distribution and independence assumptions, PLS uses objective weighting methods based on the data. Bootstrap method (B = 200) is used to calculate the mean value and standard errors of the PLS estimates. The article chooses the percentile interval to obtain the confidence interval of PLS parameters. PATIENT CONCERNS: The patients were diagnosed by the means of experts diagnosis and self-test technology. On the one hand, the patients want to know the effect of self-test by wearing a kind of instrument. On the other hand, we want to establish TCM Pectoral-qi comprehensive indicators and highlight the inner structure among different variables in an objective way. DIAGNOSES: The group of 59 subjects are the same no matter whether they were diagnosed through TCM Pectoral-qi Assessment Questionnaire of self-test technology. INTERVENTIONS: The same group of 59 subjects keep wearing the instrument for hours and get the self-test data consequently. OUTCOMES: As one of comprehensive indicator establishing methods, PLS-SLVM highlights the structure state among variables and improves the evaluation efficiency. Furthermore, it provides a new tool and method in TCM diseases prevention and health security. LESSONS: As expected, PLS-SLVM is a useful tool due to its nonassumption of normal distribution and independence with consideration of correlation among different variables. Thus PLS-SLVM can be applied in ordinal data from assessment questionnaire and continuous data about physicochemical indexes for the same group of people. It displays that PLS-SLVM builds a connection between TCM experts diagnosis and the self-testing technology. PMID- 29443768 TI - Association of human leukocyte antigen (HLA)-DQ and HLA-DQA1/DQB1 alleles with Vogt-Koyanagi-Harada disease: A systematic review and meta-analysis. AB - OBJECTIVE: The aim of this study was to evaluate the association of human leukocyte antigen (HLA)-DQ and HLA-DQA1/DQB1 alleles with Vogt-Koyanagi-Harada (VKH), providing further evidences on the genetic background of this disease. METHODS: A comprehensive literature search was conducted on the relationship of HLA-DQ and/or HLA-DQA1/DQB1 alleles with VKH through PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, VIP, and databases for grey literature. The last search was in October 2017. Pooled odds ratio (OR) with 95% confidence interval (95% CI) was calculated from extracted data to access the strength of the association between a genotype and VKH. RESULTS: HLA-DQ4 was confirmed to increase the risk of VKH significantly (OR = 4.63, 95% CI: 1.74 12.31, P = .002), while HLA-DQ1 seemed to reduce VKH occurrence with OR = 0.32 (95% CI: 0.22-0.47, P < .00001). HLA-DQA1*0301-(OR = 4.52, 95% CI: 1.42-14.35, P = .01) and HLA-DQB1*0401-(OR = 23.12, 95% CI: 11.54-46.31, P < .00001) positive patients probably had a rising tendency to suffer from VKH. Alleles including HLA DQA1*0103, 0401, 0501 and HLA-DQB1*0301, 0402, 0601, 0603 were significant protective genetic factors. CONCLUSION: We concluded that HLA-DQ4 carriers had a higher risk of VKH and HLA-DQ1 seemed to be protective. People with positive HLA DQA1*0301 and HLA-DQB1*0401 demonstrated to be more susceptible to VKH. HLA DQA1*0103, 0401, 0501 and HLA-DQB1*0301, 0402, 0601, 0603 could be potential protectors. PMID- 29443770 TI - Whether innate immune together with genetic factor are involved in leukemic arthritis?: A case report and review of the literature. AB - We report a case of leukemic arthritis (LA) of monocytic differentiation, which presented with spondyloarthritis-like symptoms and a positive human leukocyte antigen-B27, and discuss its potential mechanisms.The patient was admitted because of pain in her right knee and lower back for 18 months. Magnetic resonance imaging showed diffuse hyperintense signal in the bilateral liac bones and bone marrow edema and synovitis in the right knee.The diagnosis of acute monocytic leukemia and LA were concluded by bone marrow aspiration and flow cytometry of the synovial fluid.The patient had poor response to nonsteroidal anti-inflammatory drugs. One week after she received chemotherapy, the symptoms were dramatically relieved.For 5-year follow-up, she got clinical remission without suffering pain of the right knee and the lower back.Leukemic arthritis is a rare manifestation of leukemia with unknown mechanism and may be the initial presentation of leukemia. The problem whether abnormal immune response of the neoplasitc monocytes together with hereditary factors contribute to the pathogenesis of LA in adult is raised from this case, which worth further research. PMID- 29443771 TI - Endoscopic bronchial occlusion for postoperative persistent bronchopleural fistula with computed tomography fluoroscopy guidance and virtual bronchoscopic navigation: A case report. AB - RATIONALE: The development of postoperative bronchopleural fistula (BPF) remains a challenge in thoracic surgery. We herein report a case of BPF successfully treated with endoscopic bronchial occlusion under computed tomography (CT) fluoroscopy and virtual bronchoscopic navigation (VBN). PATIENT CONCERNS: A 63 year-old man underwent right upper lobectomy with concomitant S6a subsegmentectomy for lung adenocarcinoma. On postoperative day 24, he complained of shaking chills with high fever. DIAGNOSES: BPF with subsequent pneumonia and empyema. INTERVENTIONS: Despite aggressive surgical interventions for the BPF, air leakage persisted postoperatively. On days 26 and 34 after the final operation, endobronchial occlusions were performed under CT fluoroscopy and VBN. OUTCOMES: The air leaks greatly decreased and the patient was discharged. LESSONS: CT fluoroscopy and VBN can be useful techniques for endobronchial occlusion in the treatment of BPF. PMID- 29443772 TI - Primary leiomyosarcoma in the colon: A case report. AB - RATIONALE: Leiomyosarcoma (LMS) is a common type of soft tissue sarcoma. Primary colonic LMS in general is a very rare entity, accounting for 1% to 2% of gastrointestinal malignancies. PATIENT CONCERNS: We report a case of 55-year-old female who presented with a sudden onset of sharp right lower quadrant abdominal pain. Electronic colonoscopy showed a normal lumen. However, an abdominal computed tomography scan revealed a mass of soft tissue attenuation inseparable from the ascending colon which appeared as a gastrointestinal stromal tumor (GIST). DIAGNOSES: It is important to diagnose LMS definitively by immunohistochemical profiling of smooth muscle actin, desmin, and CD34. INTERVENTIONS: She underwent laparotomy and right hemicolectomy, and histology confirmed a colonic LMS. The patient received no oncological treatment after surgery. OUTCOMES: No recurrence or metastasis was observed at 5 months postoperatively. It is crucial to identify colonic LMS precisely based on immunohistochemistry, and thereby distinguish it from GIST. LESSONS: Further investigation on LMS cases so far is required to establish standard treatment strategies. PMID- 29443773 TI - Anti-N-methyl-D-aspartate receptor encephalitis associated with acute Toxoplasma gondii infection: A case report. AB - RATIONALE: Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis has been recognized as the most frequent autoimmune encephalitis in children. Several infectious agents have been implicated in anti-NMDA encephalitis. PATIENT CONCERNS: A previously healthy immunocompetent 9-year-old girl first presented with seizures, headaches and vomiting. Cerebrospinal fluid and brain magnetic resonance imaging were normal. After one week onset, the patient gradually developed unexplained personality and behavior changes, accompanied by fever and seizures again. Repeated CSF analysis revealed a slightly lymphocytic predominant pleocytosis and positive anti-NMDAR antibody. A variety of pathogenic examinations were negative, except for positive toxoplasma IgM and IgG. DIAGNOSES: The patient was diagnoses for anti-NMDA encephalitis associated with acute acquired toxoplasma gondii infection. INTERVENTIONS: The patient received 10 days azithromycin for treatment of acquired toxoplasma infection. The parents refuse immunotherapy because substantial recovery from clinical symptoms. OUTCOMES: The patient was substantially recovered with residual mild agitation after therapy for acquired toxoplasma gondii infection. Two months later, the patient was completely devoid of symptoms, and the levels of serum IgM and IgG of toxoplasma gondii were decreased. LESSONS: Acquired toxoplasma gondii infection may trigger anti-NMDAR encephalitis in children, which has not been reported previously. Clinicians should assess the possibility of toxoplasma gondii infection when evaluating a patient with anti-NMDA encephalitis. PMID- 29443774 TI - Sanders type IIIAB calcaneal fracture without broken lateral wall: A case report and review of literature. AB - RATIONALE: The calcaneal fracture without broken lateral wall is rare and the open anatomic reduction and internal fixation (ORIF) is necessary when the subtalar joint articular surface is broken and collapsed. PATIENT CONCERNS: A 45 year-old male was admitted to our department with complaints of heel pain and swelling after falling down from 1-m-high stone. He was unable to bear weight on his right foot. DIAGNOSES: Imaging studies confirmed that it was a sanders type IIIAB calcaneal fracture without broken lateral wall and the middle part of the posterior calcaneal articular facet collapsed. INTERVENTIONS: ORIF of intraarticular calcaneal fracture with the locking calcaneal plate was performed. OUTCOMES: The patient recovered completely after 16 weeks and was able to participate in his usual work. LESSONS: Based on this case and literature we reviewed, computed tomography scan (CT scan) should be used to diagnose and evaluate the severity of calcaneal fractures. Currently, ORIF was the preferred surgical treatment option when dealing with displaced intraarticular calcaneal fractures. PMID- 29443775 TI - Primary undifferentiated pleomorphic sarcoma of the thyroid: A case report and review of the literature. AB - RATIONALE: Primary undifferentiated pleomorphic sarcoma is extremely rare in the thyroid, and can be easily misdiagnosed as anaplastic thyroid cancer. PATIENT CONCERNS: We present a case of a 71-year-old woman who presented with a rapidly growing painless mass in the neck. DIAGNOSES-INTERVENTIONS-OUTCOMES: Computed tomography showed a large hypointense mass with hyperdense areas involving whole of the right lobe of thyroid gland and fine-needle aspiration cytology found a few atypical cells. Surgical exploration was performed subsequently and frozen section showed malignant tumor. Therefore, a total thyroidectomy, central, and bilateral lateral neck dissection were performed and adjuvant radiotherapy of 60 Gy was administered. The patient was alive and had no recurrence at 6-month follow-up. LESSONS: Although primary undifferentiated pleomorphic sarcoma in the thyroid is extremely rare, patients who presented with a rapidly growing painless mass in the neck should be considered and it is essential to excise the tumor completely as soon as possible. PMID- 29443776 TI - Differential expression of microRNAs in the normal skin of the Han and Uyghur populations in Xinjiang Province. AB - In this study, we investigated the expression of microRNAs (miRNAs) in the skin samples from the Han and Uyghur populations in Xinjiang, China. The miRNA levels of the normal skin samples from 10 individuals of Uyghur or Han were tested by microarray and the expression differentiations were compared. Among the 3100 probes for microarray, a total of 247 miRNAs were differentially expressed in the Han versus Uyghur population, including 76 upregulated miRNAs and 171 downregulated miRNAs. The most significantly upregulated miRNAs were miR-141-3p, miR-1915-5p, kshv-miR-K12-2-5p, and miR-222-3p. And the most significantly downregulated miRNAs included miR-1207-3p and miR-625-3p. We have confirmed the upregulation of miR-141-3p and miR-1915-5p by qRT-PCR. There were no statistical correlations in the expression of miR-141-3p or miR-1915-5p with the age or gender within each group. Interestingly, the differentially expressed miRNAs were enriched in some cancer-related pathways, such as p53, mitogen-activated protein kinase, and WNT signal pathways. Collectively, these dysregulated expressions of the miRNAs may provide a better understanding of the differences in the incidence and mortality of skin-related carcinoma between the Uyghur and Han populations in Xinjiang. PMID- 29443777 TI - Oral leukoplakia, a precancerous lesion of squamous cell carcinoma, in patients with long-term pegylated liposomal doxorubicin treatment. AB - Pegylated liposomal doxorubicin (PLD) has a good safety profile, but long-term use has been associated with development of squamous cell carcinoma of the tongue and oral cavity (SCCTO) in some patients. The study objective was to estimate the prevalence of oral leukoplakia, a known precursor of SCCTO, in patients with ovarian cancer and long-term PLD use.After approval of the institutional review board, medical record of 114 patients who were treated with PLD at our institution between January 2010 and December 2016 were retrospectively reviewed. All those patients have been referred for routine monitoring of oral mucositis every time before administration by a dentist. The patient characteristics included in the evaluation were age, smoking and drinking habits, the PLD dose and schedule, and presence or absence of oral leukoplakia and SCCTO at each oral examination. The relationships of the incidence of oral leukoplakia and patient characteristics were analyzed.The median total PLD dose was 160 (range 40-1550) mg/m. Oral leukoplakia was seen in 6 (5.3%) patients. The median PLD dose, at the time of oral leukoplakia diagnosis, was 685 (range 400-800) mg/m. SCCTO was not found. Univariate analysis revealed that age, Brinkman index, and habitual drinking were not considered as risk factors for oral leukoplakia, and only total PLD dose (OR, 1.470; 95% CI, 1.19-1.91; P < .001) remained as a significant independent risk factor for oral leukoplakia. The ROC curve analysis indicated that the optimal cutoff value of the total PLD dose to predict development of oral leukoplakia was 400 mg/m. The sensitivity was 100% and the specificity was 88.8%. No patient discontinued PLD because of oral leukoplakia or SCCTO.The 2 most important clinical observations were the occurrence of oral leukoplakia in patients with long-term PLD use and that the development of oral leukoplakia was related to a total cumulative dose >=400 mg/m. Routine oral surveillance is recommended, particularly when the cumulative total dose exceeds 400 mg/m. PMID- 29443778 TI - A primitive neuroectodermal tumor in an adult: Case report of a unique location and MRI characteristics. AB - RATIONALE: Central nervous system primitive neuroectodermal tumors (CNS PNETs) mostly occur in children and present as cerebellar medulloblastoma. A few cases of PNETs occur in the cerebral hemisphere. The presence of a PNET in ventricles is extremely rare. The prognosis of CNS PNET is extremely poor, and the 5-year survival rate does not exceed 35%. In the present study, we describe the first case of a PNET in the ventricles with good prognosis. PATIENT CONCERNS: The case of a 36-year-old man is reported, who presented with a progressively worsening headache for 2 months. DIAGNOSES: Magnetic resonance imaging (MRI) revealed multiple tubercula on the walls of the lateral and third ventricles. Histopathologic analysis revealed a hypercellular tumor with small round cells containing hyperchromatic nuclei and a high nucleus:cytoplasm ratio. The analysis was consistent with PNET. INTERVENTIONS: Radiation therapy covering the entire craniospinal axis was administered, with Temozolomide for synchronous auxiliary treatment. OUTCOMES: The patient was follow-up for a year and showed no signs of recurrence. LESSONS: We present the first CNS PNET located in the ventricles with good prognosis. In this case, radiotherapy with Temozolomide auxiliary treatment presented good efficacy and safety to treat PNET. Additional studies on biomarkers may be useful in predicting personalized therapeutic response. PMID- 29443779 TI - Cerebral infarction due to malposition of cervical pedicle screw: A case report. AB - RATIONALE: Malposition of cervical pedicle screw (CPS) has a risk of vertebral artery (VA) injury which sometimes may cause unexpected and catastrophic outcome. A rare case of delayed onset of cerebral infarction caused by malposition of CPS was reported. PATIENT CONCERNS: A 23-year-old man who underwent a posterior cervical reduction and fusion of C4-5 using CPS fixation and allograft for cervical spine injury is presented. The patient suffered progressively weakness and numbness for both of upper and lower extremities 1 day after the operation. Computed tomography scans revealed bilateral occupation of the pedicle screws in the foramen of C4 and C5 and the magnetic resonance imaging (MRI) displayed several areas of infarction in the brainstem and cerebellum. DIAGNOSES: Plain radiographs of the cervical spine revealed the C4 vertebral body and MRI displayed a disruption of the anterior longitudinal ligament on the level of C4-5 and severe injury to the soft tissues of the cervical spine at admission. Brainstem and cerebellum infarction was diagnosed at postoperative. INTERVENTION: A revision surgery was decided to remove all of the pedicle screws and place lateral mass screws instead. OUTCOMES: The patient felt better on his all of 4 extremities following revision surgery. Fortunately, he was neurologically close to normal at a 3-month follow-up. LESSONS: Delayed onset of cerebral infarction is rarely reported complication caused by malposition of CPS. When a CPS perforates the transverse foramen and causes symptom of cerebral infarction, a revision surgery in time is strongly recommended to prevent further sequelae. PMID- 29443780 TI - Analysis of the characteristics of optical coherence tomography angiography for retinal cavernous hemangioma: A case report. AB - RATIONALE: Retinal cavernous hemangioma is a rare congenital vascular malformation with typical fundus changes. Optical coherence tomography angiography (OCTA), which is in rise in the recent years, is a rapid and noninvasive technology to assist in obtaining information regarding the blood flow changes in the fundus lesions from different layers without injecting a contrast agent. PATIENT CONCERNS: A 40-year-old male patient with visual occlusion in the right eye for >1 month was reported. DIAGNOSES: Retinal cavernous hemangioma was diagnosed by fundus examination, fluorescein angiography (FA) and OCTA, and the characteristics of OCTA images were analyzed. INTERVENTIONS: The lesion occurred outside the macula, the central vision remained basically normal, and no significant complications were noted in this patient. Therefore, we preferred to regularly follow-up without therapeutic intervention. CONCLUSIONS: OCTA can display fundus blood flow and vascular lesions noninvasively and rapidly. On OCTA, retinal cavernous hemangiomas showed characteristic changes and have good correspondence with fundus imaging and FA examinations. Moreover, OCTA remains more sensitive to vascular abnormalities, and imaging remains clearer, providing new diagnosis and follow-up route for this disease. PMID- 29443781 TI - Unexpected custodial death due to acute epiglottitis: A rare autopsy case report. AB - RATIONALE: Acute epiglottitis is a potentially life-threaten disease, which makes it more challenging to save the life for doctors. Unexpected deaths in custody are a primary cause of concern for the forensic community and doctor worldwide. PATIENT CONCERNS: We present a case of a 44-year-old male detainee who was clinically suspected of dying of acute epiglottitis. The man experienced failure of resuscitation and died after admitted to a hospital. DIAGNOSES: The autopsy, toxicological testing, the test of immunoglobulin E and bacterial culture suggested the patient died of acute epiglottitis. INTERVENTIONS: The bacterial culture was performed to imprecisely identify the cause of death. OUTCOMES: The bacterial culture of the patient's heart blood and nasal and throat swabs showed the presence of the pathogenic microorganism Haemophilus influenza type B. LESSONS: We aim to provide a reference to the medical and forensic community and remind the local law enforcement agencies on the problems present within the correctional healthcare system through this case report. Additionally, we also aim to increase the current knowledge and understanding on custodial deaths caused by natural diseases. PMID- 29443783 TI - Giant GIST of the stomach: a successful case of safe resection with preoperative simulation using three-dimensional CT angiography: Case report. AB - RATIONALE: We report a very rare case of safely resectable giant gastrointestinal stromal tumor (GIST) with preoperative three-dimensional computed tomography (3D CT) angiography in spite of no neoadjuvant treatment. PATIENT'S CONCERN: A 71 year-old woman presented to our hospital with an abdominal giant tumor. As this giant tumor could not be accurately diagnosed by preoperative investigation, we had to perform her surgical treatment without neoadjuvant treatment. However, preoperative 3D-CT angiography clearly showed that the tumor was supplied by the right gastroepiploic artery (RGA). Based on the preoperative information, a surgical procedure was undertaken. DIAGNOSIS: Giant tumor of stomach with suspicion of GIST. INTERVENTIONS: Laparotomy guided by 3D-CT imaging including angiography. OUTCOME: The giant tumor originated from the greater curvature of the distal stomach and was supplied by the RGA, as expected. The tumor was resected easily under the accurate preoperative anatomical information. The tumor measured 20 cm * 20 cm in size and weighed 2500 g (Fig. 2C and D). Histopathological examination showed evidence of growth of spindle-shaped cells and a low mitotic index (3 per 50 high-power field, Fig. 3B). Immunohistochemical examination showed positive immunoreactions for KIT, CD34, and DOG1 (Fig. 3 C-E), but negative ones for SMA and S-100 protein (Fig. 3F and G). Consequently, we made a final diagnosis of an extra luminal GIST of the stomach. The post operative course was uneventful, and so the patient was discharged on postoperative day 13. LESSONS: Making full use of an imaging procedure such as 3D CT angiography is one of the effective tools for the surgical management of giant size tumors including giant GISTs. PMID- 29443782 TI - Putative lung adenocarcinoma with epidermal growth factor receptor mutation presenting as carcinoma of unknown primary site: A case report. AB - RATIONALE: Only a few cases of putative lung adenocarcinoma presenting as carcinoma of unknown primary site (CUP) with epidermal growth factor receptor (EGFR) mutation have been reported, and the efficacy of EGFR-tyrosine kinase inhibitors (TKIs) for these cases is unclear. PATIENT CONCERNS AND DIAGNOSES: A 67-year-old man complained of paresis of the right lower extremity, dysarthria, and memory disturbance. Computed tomography and magnetic resonance imaging showed multiple brain tumors with brain edema and swelling of the left supraclavicular, mediastinal, and upper abdominal lymph nodes. Moreover, a metastatic duodenal tumor was detected via upper gastrointestinal endoscopy examination. The biopsy specimen of the lesion was examined and was diagnosed as adenocarcinoma with CK7 and TTF-1 positivity. Finally, the case was diagnosed as EGFR mutation-positive putative lung adenocarcinoma presenting as CUP. INTERVENTIONS AND OUTCOMES: Oral erlotinib, an EGFR-TKI, was administered at 150 mg daily. Five weeks later, the brain lesions and several swollen lymph nodes showed marked improvement, and the symptoms of the patient also improved. Three months later, the duodenal lesion was undetected on upper gastrointestinal endoscopy. After an 8-month follow-up, the patient was well with no disease progression. LESSONS: Putative lung adenocarcinoma presenting as CUP may have EGFR mutation, and EGFR-TKI therapy may be effective for such malignancy. PMID- 29443784 TI - A thyroid storm patient with protracted disturbance of consciousness and reversible lesion in the splenium of corpus callosum: A case report. AB - RATIONALE: Various neurological manifestations are observed in thyroid storm patients but protracted disturbance of consciousness is rare. PATIENT CONCERNS: A 58-year-old male was admitted to our hospital after a traffic accident. DIAGNOSES: Although awake on arrival, he fell into coma after admission. Based on the clinical symptoms and hyperthyroidism, the patient was diagnosed with thyroid storm (TS). INTERVENTIONS: Even after improvement of hyperthyroidism, disturbance of consciousness was protracted. Considering the possibility of immune-related etiology, methylprednisolone pulse was started. OUTCOMES: His consciousness level improved over a 3-month period, and he became able to walk with some assistance after 6 months. LESSONS: His condition was atypical of TS-associated encephalopathy because of the long clinical course. Reversible splenial lesion was visible using brain imaging. In some cases of TS, disturbance of consciousness can be protracted for several months, but it is reversible. Therefore, it is necessary to judge the long-term neurological outcome carefully. PMID- 29443785 TI - Can endotracheal intubation be the first step in management of nonconvulsive status epilepticus?: A case report. AB - RATIONALE: Nonconvulsive status epilepticus (NCSE) is prolonged seizure activity without motor manifestations. Clinically, there are certain examination findings, in addition to elements of history, that help differentiate it from other encephalopathies. When diagnosing NCSE, the physician faces significant difficulties due to inconsistent clinical presentation and somewhat nonspecific electroencephalogram (EEG) criteria. PATIENT CONCERNS: To highlight the problems faced when dealing with such a patient, a case of a 29-year-old male who presented with an altered state of consciousness is put forth for the reader. Only after an extensive laboratory and radiological workup had ruled out other causes, an eventual diagnosis was established when clinical features were correlated with suggestive EEG results. DIAGNOSES: The diagnosis that was reached was NCSE. INTERVENTIONS: The initial therapeutic interventions generally deployed in such a scenario ultimately failed and consequently the patient had to be sedated and intubated, while being kept on antiepileptic medication. OUTCOMES: This measure resulted in satisfactory recovery. LESSONS: Accordingly, we recommend consideration of NCSE in any unconscious patient whose presentation cannot be explained by other disorders. Furthermore, we suggest moving directly to utilizing anesthetic agents and endotracheal intubation, together with anti epileptic drugs, in the treatment regimen in order to optimize patient outcomes. PMID- 29443786 TI - Improved vacuum sealing drainage for treatment of surgical site infection following posterior spinal internal fixation: A case report. AB - RATIONALE: Surgical site infection (SSI) following spine surgeries involving internal fixation often require removing the instrument; however, this can cause spinal instability. Previous reports have demonstrated the usefulness of vacuum sealing drainage (VSD) therapy, but the cases require wound opening, aseptic condition to replace the VSD device, and a secondary operation to close the wound. Thus, to improve the VSD treatment and develop a maneuverable procedure, make sense in spine surgery. PATIENTS CONCERNS: A 59-year-old male patient with a T12 vertebral fracture was affected by SSIs after spinal osteotomy with internal fixation. DIAGNOSES: The patient complained of wound exudation and had a fever 3 weeks after posterior spinal surgery. Initial serum investigations showed elevated white blood cell count and bacterial cultures of wound exudate were positive for Enterococcus faecalis. Therefore, SSI is confirmed. INTERVENTIONS: The infection was not controlled after 2 debridements, so the patient was treated with VSD treatment. The VSD foam dressings containing a drainage tube were placed into the wound from the exudation site of the wound until they contacted the internal fixation devices. After covering external fixation devices, continuous drainage was performed for 24 h. The VSD device was replaced every 4 to 5 days until the wound effusion stopped. All of the operations were performed at the bedside without complex manipulation or secondary closure under harsh aseptic condition. OUTCOMES: Wound exudation decreased remarkably and the infection was controlled 2 weeks after the application of VSD treatment. After 5 weeks, inflammatory indicators all decreased to normal levels and the exudate of the wound had stopped. The VSD treatment was then terminated and the drainage site of the wound was sutured. After 7 weeks, complete wound healing was achieved and no infection recurred during the 6-month follow-up. LESSONS: VSD could be a reliable treatment for SSIs that require preservation of internal fixation. Complete opening of the wound during the VSD treatment and secondary wound closure surgery were avoided. PMID- 29443787 TI - Spontaneous cerebrospinal fluid rhinorrhea: A case report and analysis: Erratum. PMID- 29443788 TI - A prospective, randomized, open label, controlled study investigating the efficiency and safety of 3 different methods of rectus sheath block analgesia following midline laparotomy. AB - BACKGROUND: There is a controversy regarding the efficacy of rectus sheath block (RSB). The aim of the present study was to evaluate analgesic efficacy and safety of three different methods of RSB in postoperative pain management after midline laparotomy. METHODS: A prospective, randomized, controlled, open-label clinical trial with 4 parallel groups was conducted in a tertiary care hospital in Finland. A total of 57 patients undergoing midline laparotomy were randomized to the control group (n = 12) or to 1 of the 3 active RSB analgesia groups: single dose (n = 16), repeated-doses (n = 12), or continuous infusion (n = 17). Opioid consumption with iv-patient-controlled analgesia pump was recorded, and pain scores and patients' satisfaction were surveyed on an 11-point numeric rating scale for the first 48 postoperative h. Plasma concentrations of oxycodone and levobupivacaine were analyzed. All adverse events during the hospital stay were recorded. RESULTS: Oxycodone consumption was less during the first 12 h in the repeated-doses and in the continuous infusion groups (P = .07) and in numerical values up to 48 h in the repeated-doses group. Plasma oxycodone concentrations were similar in all 4 groups. Pain scores were lower in the repeated-doses group when coughing during the first 4 h (P = .048 vs. control group), and at rest on the first postoperative morning (P = .034 vs. the other 3 groups) and at 24 h (P = .006 vs. the single-dose group). All plasma concentrations of levobupivacaine were safe. The patients' satisfaction was better in the repeated-doses group compared with the control group (P = .025). No serious or unexpected adverse events were reported. CONCLUSIONS: RSB analgesia with repeated-doses seems to have opioid sparing efficacy, and it may enhance pain relief and patients' satisfaction after midline laparotomy. PMID- 29443789 TI - Polymorphisms of drug-metabolizing enzyme CYP2E1 in Chinese Uygur population. AB - Pharmacogenetics is the genetic basis of pharmacokinetics, genetic testing, and clinical management in diseases. Evaluation about genetic alterations of drug metabolizing enzymes in human genome contributes toward understanding the interindividual and interethnic variability for clinical response to potential toxicants. CYP2E1 gene encodes a drug-metabolizing enzyme that metabolizes mostly small, polar molecules, including toxic laboratory chemicals. The aim of this study was to investigate CYP2E1 polymorphisms and gene profile in a Chinese Uygur population. Frequencies for the CYP2E1 mutated alleles and genotypes were screened in 100 unrelated random healthy Uygur volunteers. PCR and direct sequencing revealed a total of 32 polymorphisms, of which 5 novel mutations were presented. Rs 943975 was the most common single nucleotide polymorphism (SNP). The allele frequencies of CYP2E11A, 4, 7A, and 7C were 65.5, 2, 19.5, and 13%, respectively. The most common genotype combinations were CYP2C191A/1A (43%) and 1A/7C (24%). Functional prediction for 2 nonsynonymous mutations G173S and V179I was performed using MutationTaster, sorting intolerant from tolerant, and PolyPhen-2. The observations of the present study give rise to useful information on CYP2E1 polymorphisms in Chinese Uygur individuals. The results suggest important clinical implications for the use of medications metabolized by CYP2E1 among Uygurs. PMID- 29443790 TI - Rotational atherectomy ablation for an unexpandable stent under the guide of IVUS: A case report. AB - RATIONALE: Inadequate stent expansion due to rigid calcified may result in restenosis lesions, but the available options are limited. PATIENT CONCERNS: We report a case via the trans-radial approach of the severely underexpanded freshly deployed stent due to heavily calcified plaques DIAGNOSES:: Coronary angiography revealed that there was no adequate expansion of the freshly deployed stent. INTERVENTIONS: Under the guide of intravascular ultrasound (IVUS), rotational atherectomy (RA) successfully ablated the stent layers and the protruding calcified plaque. Followed by balloon angioplasty, the ablated segment was scaffolded with another stent, well expanded and documented by IVUS. OUTCOMES: The patient was uneventful during the procedure and remained angina free at the point of one year of clinical follow-up. LESSONS: This case indicated that RA via the trans-radial approach could be a useful remedy in the situation of under expansion of implanted stents, and the debulking should be performed under IVUS guidance. PMID- 29443791 TI - Direction-changeable lumbar cage versus traditional lumbar cage for treating lumbar spondylolisthesis: A retrospective study. AB - Despite the diverse designs for the lumbar interbody fusion cage, there is no consensus on the optimal design to date. The current study aimed to compare the efficacy and complications associated with the direction-changeable and traditional lumbar cages for treating lumbar spondylolisthesis.We conducted a retrospective study including 109 patients with lumbar spondylolisthesis, who were admitted to our hospital from January 2013 to December 2014. The patients were divided into the direction-changeable (group A) and traditional (group B) lumbar cage group.All patients underwent single-level transforaminal lumbar interbody fusion and were followed up for 12 to 24 months. There were 52 cases in group A and 57 cases in group B. Surgery-related parameters, including operation time, bleeding volume, and hospitalization time, were recorded; there was no significant difference between the 2 groups regarding these parameters. The visual analog scale and Oswestry disability index at the last follow-up showed significant improvement compared with preoperative values in both groups (P < .05). Patients in group A demonstrated more intervertebral space height maintenance postoperatively than patients in group B but the difference was not statistically significant (P > .05). In group A, complications included 3 cases of nonunion (5.77%) and 1 case of cerebrospinal fluid leakage (1.92%). In group B, complications included 9 cases of nonunion (15.79%) and 1 case of postoperative infection (1.75%). There was a significant difference between both groups in terms of the nonunion rate and total complication rate (P < .05).The direction-changeable lumbar cage has merits such as a higher bone fusion rate and fewer postoperative complications compared to the traditional lumbar cage. PMID- 29443792 TI - Pleural cavity cytokine release syndrome in CD19-directed chimeric antigen receptor-modified T cell therapy: A case report. AB - RATIONALE: Cytokine release syndrome (CRS) is a common and potentially fatal complication of CAR-T cell therapy. However, compartment CRS is relatively rare in hematological malignancies, as well as in solid tumors. The pathogenesis and prognosis of compartment CRS are unclear and there is no standardized treatment yet. In this case report, we will introduce a patient developing pleural cavity CRS after CART19s infusion. PATIENT CONCERNS: A 28-year-old woman was admitted for evaluation of mediastinal mass. Her relevant examinations were comoleted. DIAGNOSES: She was diagnosed as diffuse large B cell lymphoma (DLBCL, non-GCB type). INTERVENTIONS: She received chemotherapies including 1 cycle of R DAEPORCH, 1 cycle of R-CHOPE, 2 cycles of R-CHOP, and 4 cycles of R-GDP during the disease course. OUTCOMES: The cytokine levels of hydrothorax were considerably high when serum cytokines were within normal range, with IL-6 at 1212.45 versus 5.69 pg/mL. qPCR analysis for CAR constructs showed 1,119,696 copies/MUg DNA in hydrothorax and 522,227 copies/MUg DNA in blood. LESSONS: The results indicated that CART19 cells trafficked to the pleural cavity and interacted with the CD19-positive lymphoma cells directly, causing cytokine release in situ. PMID- 29443793 TI - Olanzapine-induced peripheral eosinophilia and eosinophilic pleural effusion: A case report. AB - RATIONALE: Eosinophilic pleural effusion (EPE) is an eosinophil count >=10% in pleural effusion, which is a rare condition in drug therapy. PATIENT CONCERNS: We describe the case of a 70-year-old Alzheimer patient who was taking olanzapine for 2 months for the treatment of depression, and developed peripheral eosinophilia and bilateral EPE. DIAGNOSES: Olanzapine-induced peripheral eosinophilia and eosinophilic pleural effusion was diagnosed. INTERVENTIONS: Olanzapine was discontinued, and repeated drainage of fluid from the pleural cavity was performed. OUTCOMES: All symptoms-as well as the EPE-were resolved 6 months later. LESSONS: This case is a reminder that olanzapine may be a potential agent for EPE, and that this should be considered in clinical practice. PMID- 29443794 TI - Stability of Early EEG Background Patterns After Pediatric Cardiac Arrest. AB - PURPOSE: We aimed to determine whether EEG background characteristics remain stable across discrete time periods during the acute period after resuscitation from pediatric cardiac arrest. METHODS: Children resuscitated from cardiac arrest underwent continuous conventional EEG monitoring. The EEG was scored in 12-hour epochs for up to 72 hours after return of circulation by an electroencephalographer using a Background Category with 4 levels (normal, slow disorganized, discontinuous/burst-suppression, or attenuated-featureless) or 2 levels (normal/slow-disorganized or discontinuous/burst-suppression/attenuated featureless). Survival analyses and mixed-effects ordinal logistic regression models evaluated whether the EEG remained stable across epochs. RESULTS: EEG monitoring was performed in 89 consecutive children. When EEG was assessed as the 4-level Background Category, 30% of subjects changed category over time. Based on initial Background Category, one quarter of the subjects changed EEG category by 24 hours if the initial EEG was attenuated-featureless, by 36 hours if the initial EEG was discontinuous or burst-suppression, by 48 hours if the initial EEG was slow-disorganized, and never if the initial EEG was normal. However, regression modeling for the 4-level Background Category indicated that the EEG did not change over time (odds ratio = 1.06, 95% confidence interval = 0.96-1.17, P = 0.26). Similarly, when EEG was assessed as the 2-level Background Category, 8% of subjects changed EEG category over time. However, regression modeling for the 2-level category indicated that the EEG did not change over time (odds ratio = 1.02, 95% confidence interval = 0.91-1.13, P = 0.75). CONCLUSIONS: The EEG Background Category changes over time whether analyzed as 4 levels (30% of subjects) or 2 levels (8% of subjects), although regression analyses indicated that no significant changes occurred over time for the full cohort. These data indicate that the Background Category is often stable during the acute 72 hours after pediatric cardiac arrest and thus may be a useful EEG assessment metric in future studies, but that some subjects do have EEG changes over time and therefore serial EEG assessments may be informative. PMID- 29443795 TI - POSTERIOR PRECORTICAL VITREOUS POCKETS IN HIGH MYOPIA OBSERVED BY ENHANCED VITREOUS IMAGING OF SPECTRAL DOMAIN OPTICAL COHERENCE TOMOGRAPHY. AB - PURPOSE: To observe the vitreous in highly myopic eyes with posterior precortical vitreous pockets (PPVPs) using enhanced vitreous imaging of spectral domain optical coherence tomography. METHODS: Fifty-two highly myopic eyes with PPVPs of 36 patients were included in this study. All subjects underwent enhanced vitreous imaging optical coherence tomography. The size of PPVPs was measured, and the frequency of imaging features was recorded. RESULTS: Nine imaging features of the vitreous in highly myopic eyes with PPVPs were found. The average age of subjects was 38.1 +/- 10.8 years. The mean height of PPVPs was 1,177 +/- 704 MUm, and the mean width was 7,440 +/- 755 MUm. Hyperreflective line and the interlayer were observed in 30 (57.7%) eyes. Hyperreflective dots were found in 37 (71.2%) eyes. More central vitreous space was more frequently detected in younger patients. Prevascular vitreous fissure was detected in 7 (13.5%) eyes. W-shaped cavity, identified as an empty space with a smooth W-shaped edge, was demonstrated to be the fusion of Cloquet's canal and the extension of PPVPs. Perpendicular hyperreflective parallel strands were detected in 3 (5.8%) eyes. Hyperreflective network was observed in 10 (19.2%) eyes. Hyperreflective parapapillary tubercle was found in 7 (13.5%) eyes. CONCLUSION: Nine imaging features of the vitreous in highly myopic eyes with PPVPs were visualized by enhanced vitreous imaging optical coherence tomography. PMID- 29443796 TI - Correspondence. PMID- 29443797 TI - OUTCOME OF ENDOVASCULAR PROCEDURES ON OCULAR FINDINGS IN TAKAYASU ARTERITIS. AB - PURPOSE: To evaluate the outcome of endovascular procedures on ocular findings in patients with Takayasu arteritis. METHODS: Retrospective study of patients who underwent percutaneous endovascular stenting of aortic arch arteries for Takayasu arteritis (TA) and who had documented retinopathy findings before and after the procedure. Change in visual acuity, regression of retinopathy, and development of complications after endovascular procedure were studied over a follow-up of 6 months. RESULTS: Ten eyes of five patients were included. Eyes which had Stage II or less of retinopathy before the endovascular procedure had favorable outcome; however, those with advanced stage of retinopathy at presentation had poor outcomes. Patients who underwent revascularization of both-sided arteries within 1 month had better anatomical and functional outcomes as compared with those who underwent sequential endovascular procedures on their arteries after a gap of 3 months or more. CONCLUSION: Percutaneous endovascular stenting of aortic arch arteries, affected in TA, can lead to reversal of retinopathy changes and restoration of vision if done before neovascular complications set in. PMID- 29443798 TI - CLINICAL FEATURES, IMAGING, AND NATURAL HISTORY OF MYELINATED RETINAL NERVE FIBER LAYER. AB - PURPOSE: To evaluate the natural history of myelinated retinal nerve fiber layer (MRNFL) through clinical features and enhanced depth imaging optical coherence tomography. METHODS: This is a retrospective, noncomparative, case series of patients who underwent thorough clinical examination to document associated ocular and systemic features. Enhanced depth imaging optical coherence tomography was performed when MRNFL was located posteriorly and accessible to imaging. RESULTS: Seventy-two eyes of 62 patients had a total of 86 MRNFL lesions. Enhanced depth imaging optical coherence tomography (n = 42 eyes) showed that all lesions originated in the nerve fiber layer with preservation of the vascular structures. Mean thickness by enhanced depth imaging optical coherence tomography was 255 MUm (median, 182 MUm; range, 61-717 MUm). Natural history was obtainable in 58 lesions with a mean follow-up duration of 57 months (median, 37 months; range, 2-253 months) with no significant change overall in largest basal diameter (2.5 vs. 2.5 mm; P = 0.361) or thickness (255 vs. 240 MUm; P = 0.053). However, evidence of lesion change included growth in base only (>=0.5 mm) (3 of 58; 5%), growth in base (>=0.5 mm) and thickness (>=50 MUm) (3 of 58; 5%), and reduction in base (>=0.5 mm) after plaque radiotherapy for choroidal melanoma (3 of 58; 5%). CONCLUSION: In general, MRNFL is a rare, benign retinal finding with a potential for growth in 10% of cases. This supports previous histopathological reports that MRNFL represents accumulation of both myelin and oligodendrocytes and could be an oligodendrocytic choristoma.

PMID- 29443802 TI - FULL-THICKNESS MACULAR HOLE WITH MACULAR INTRACHOROIDAL CAVITATION IN A PATIENT WITH PATHOLOGIC MYOPIA. AB - PURPOSE: To describe a full-thickness macular hole (MH) opening to macular intrachoroidal cavitation in a patient with pathologic myopia. METHODS: Full ophthalmologic examination, fundus camera (Topcon TRC; Topcon Co, Tokyo, Japan), optical coherence tomography (RetinaScan Advanced RS-3000; NIDEK, Gamagori, Japan) imaging, and cataract surgery. RESULTS: A 61-year-old woman admitted with decreased vision in the left eye. Visual acuity was counting fingers from 30 cm. Anterior segment examination showed advanced cataract. Fundus examination revealed pathologic myopia. There was full-thickness MH opening to macular intrachoroidal cavitation in contact with the anterior surface of the sclera subfoveally. Except for the communicating part of MH and macular intrachoroidal cavitation, outer retina, ellipsoid zone, and retinal pigment epithelium were intact. Choroid was intact except for a small part at subfoveal area. The patient received an uncomplicated cataract surgery. Visual acuity improved to 5/10. Because she was satisfied, MH surgery was postponed to a later date. CONCLUSION: Full-thickness MH may occur within the area of macular intrachoroidal cavitation in pathologic myopia. PMID- 29443801 TI - Reply. PMID- 29443803 TI - NEWLY DIAGNOSED ASYMPTOMATIC RETINAL ASTROCYTIC HAMARTOMA IN AN OLDER ADULT. AB - BACKGROUND: To report a coincidentally discovered retinal astrocytic hamartoma in an asymptomatic older woman with no history of tuberous sclerosis or neurofibromatosis. METHODS: A 63-year-old Turkish woman underwent routine ophthalmic examination. RESULTS: Visual acuity was 20/25 in each eye. On fundus examination, the right eye showed a flat yellow-white superficial retinal lesion in the inferotemporal macula and measuring 1 mm in diameter. The lesion was unmeasurable using B-mode ultrasonography. Spectral domain optical coherence tomography revealed the mass with thickening in the retinal nerve fiber layer, with minor disorganization of the underlying retina and no retinal or vitreoretinal traction. Fluorescein angiography disclosed the mass as early isofluorescence with late mild hyperfluorescence, without leakage. Findings in the left eye were normal. Based on the clinical and imaging results, a diagnosis of noncalcified small retinal astrocytic hamartoma was rendered. The lesion remained unchanged at 1-year follow-up. CONCLUSION: Small coincidentally discovered retinal astrocytic hamartomas in older patients can be difficult to diagnose and possibly cause diagnostic confusion with other conditions including myelinated nerve fiber and cotton wool spot. Retinal astrocytic hamartoma is characterized by thickening of the retinal nerve fiber layer and mild compression and disorganization of the underlying retinal layers on spectral domain optical coherence tomography. PMID- 29443804 TI - PROGRESSION OF RETINAL ISCHEMIA IN A CASE OF MACULAR TELANGIECTASIA TYPE 1 AFTER RANIBIZUMAB INJECTION: OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY FINDINGS. AB - PURPOSE: To describe a case of a 68-year-old man with macular telangiectasia (MacTel) Type 1 in the right eye, showing an increase in capillary ischemia after intravitreal ranibizumab. METHODS: The patient underwent complete ophthalmologic evaluation, including best-corrected visual acuity, intraocular pressure, anterior segment and fundus examination, optical coherence tomography (OCT), and OCT angiography at baseline and on each visit. Fluorescein angiography was performed at baseline. The patient was followed up on monthly bases for 22 months. RESULTS: The patient presented a best-corrected visual acuity of 20/80 in the right eye and of 20/25 in the left eye at baseline. In the right eye, the fluorescein angiography images showed perifoveal capillary ectasia, late-frames dye leakage, and enlargement of the foveal avascular zone. The OCT showed intraretinal pseudocysts and microaneurysms, and the OCT angiography showed vascular rarefaction, capillary dropout, and capillary ectasia of the superficial plexus. After 16 months of follow-up and four ranibizumab injections, the best corrected visual acuity was 20/60, and the OCT angiography disclosed a further enlargement of the foveal avascular zone area and increased capillary obliteration in the perifoveal nasal area. CONCLUSION: Optical coherence tomography angiography may represent an indispensable diagnostic technique, complementary to traditional imaging, in the evaluation of the effects of anti vascular endothelial growth factor therapy in patients with MacTel Type 1. PMID- 29443805 TI - NITINOL FLEX LOOP-ASSISTED RETRIEVAL AND SUTURELESS INTRASCLERAL REFIXATION OF A DISLOCATED INTRAOCULAR LENS IMPLANT. AB - BACKGROUND/PURPOSE: To describe a novel use of the flexible nitinol loop membrane scraper (FINESSE Flex loop; Alcon, Fort Worth, TX) for rescue and refixation of a dislocated intraocular lens (IOL). METHODS: A 27-gauge nitinol flex loop was used to lasso each haptic of a dislocated 3-piece IOL. By retracting the loop, the haptic could be effectively locked to the instrument and externalized through a scleral tunnel, thereby fixating it to the sclera in a sutureless fashion. RESULTS: A 50-year-old man presented with a posteriorly dislocated Sensar AR40e IOL (Abbott Medical Optics, Inc; Santa Barbara, CA) and retained lens material after a complicated cataract surgery in the left eye. His visual acuity was counting fingers at face. The patient underwent 27-gauge pars plana vitrectomy with successful rescue and refixation of the IOL using the nitinol flex loop. One week postoperatively, his visual acuity had improved to 20/40. CONCLUSION: The nitinol flex loop may be used to lasso the haptics of a dislocated IOL and refixate it using a sutureless intrascleral fixation technique. This instrument may be a safer alternative compared with forceps for retrieving posteriorly dislocated IOLs that are sitting on the retinal surface. PMID- 29443806 TI - HAND-HELD OPTICAL COHERENCE TOMOGRAPHY MONITORING OF CHEMORESISTANT RETINOBLASTOMA. AB - PURPOSE: Retinoblastoma (Rb) is a potentially fatal intraocular malignancy in children, and hand-held optical coherence tomography (HH-OCT) can assist in submillimeter detection and monitoring after treatment of Rb. Retinoblastoma located in the macula, or those with chemoresistance, can be among the most difficult to manage. We describe HH-OCT features in a case of chemoresistant macular Rb that eventually responded to plaque radiotherapy after failing intravenous chemotherapy and intraarterial chemotherapy. METHODS: Observational case report. RESULTS: A 15-month-old girl with leukocoria was found to have Group D Rb in the right eye of 6-mm thickness and macular Group B Rb in the left eye of 4-mm thickness. She was treated with 6-monthly cycles of systemic intravenous chemotherapy and focal consolidation therapies to both eyes, with tumor regression in both eyes. However, macular tumor in the left eye demonstrated subsequent recurrence, from regressed thickness of 792 MUm on HH-OCT to a dome shaped hyperreflective retinal mass of >2000 MUm thickness. Three cycles of intraarterial chemotherapy were sufficient for tumor regression down to 977 MUm thickness on HH-OCT. Six months later, macular tumor in the left eye recurred again to >2000 MUm thickness and necessitated plaque radiotherapy using apex dose of 35 Gy over 95.25 hours. Hand-held OCT confirmed rapid tumor regression to 722 MUm after plaque treatment and regression remained stable at 6-month follow-up. CONCLUSION: Hand-held OCT was critical in assessment of Rb after failed intravenous chemotherapy and intraarterial chemotherapy and later documenting regression after plaque radiotherapy. Hand-held OCT is vital in providing cross sectional imaging and measurements of small macular and paramacular Rbs. PMID- 29443807 TI - MULTIMODAL IMAGING OF ANGIOID STREAKS ASSOCIATED WITH TURNER SYNDROME. AB - PURPOSE: To report multimodal imaging in a novel case of angioid streaks in a patient with Turner syndrome with 10-year follow-up. METHODS: Case report of a patient with Turner syndrome and angioid streaks followed at Bellevue Hospital Eye Clinic from 2007 to 2017. Fundus photography, fluorescein angiography, and optical coherence tomography angiography were obtained. RESULTS: Angioid streaks with choroidal neovascularization were noted in this patient with Turner syndrome without other systemic conditions previously correlated with angioid streaks. CONCLUSION: We report a case of angioid streaks with choroidal neovascularization in a patient with Turner syndrome. We demonstrate that angioid streaks, previously associated with pseudoxanthoma elasticum, Ehlers-Danlos syndrome, Paget disease of bone, and hemoglobinopathies, may also be associated with Turner syndrome, and may continue to develop choroidal neovascularization, suggesting the need for careful ophthalmic examination in these patients. PMID- 29443808 TI - RETINAL MICROVASCULATURE ALTERATION IN PARACENTRAL ACUTE MIDDLE MACULOPATHY AND ACUTE MACULAR NEURORETINOPATHY: A QUANTITATIVE OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY STUDY. AB - PURPOSE: To present a series of idiopathic paracentral acute middle maculopathy (PAMM) and acute macular neuroretinopathy (AMN) cases and to compare the microvascular retinal status of PAMM/AMN eyes with those of healthy individuals. METHODS: Six eyes with PAMM and two eyes with AMN in a total of six patients were included in this study. Multimodal retinal imaging, including optical coherence tomography angiography, was performed in all patients. The vessel density of the superficial capillary plexus and deep capillary plexus, as well as the area, circularity, and angle of the superficial foveal avascular zone (FAZ) were measured and compared with the same parameters in age-matched healthy individuals. RESULTS: The optical coherence tomography angiography showed a decreased vessel density of both superficial capillary plexus and deep capillary plexus in PAMM/AMN eyes versus control eyes (12.2 +/- 0.74 vs. 14.0 +/- 1.62 mm [P = 0.01] in superficial capillary plexus and 18.5 +/- 1.2 vs. 20.2 +/- 1.0 mm [P = 0.02] in deep capillary plexus). There was no statistically significant change in the FAZ area between PAMM/AMN and healthy eyes. However, FAZ circularity in PAMM/AMN eyes was statistically significantly lower compared with healthy eyes (0.64 +/- 0.09 and 0.77 +/- 0.07, respectively; P = 0.01). The angle of FAZ was statistically significantly higher in PAMM/AMN eyes compared with healthy eyes (27.6 +/- 16.2 and 11.2 +/- 5.5 degrees , respectively; P = 0.005). CONCLUSION: Paracentral acute middle maculopathy and AMN eyes demonstrated not only an isolated alteration of deep retinal circulation but also general nonspecific changes in retinal microvasculature, including a decrease in the vessel density of the superficial capillary plexus and distortion of the FAZ.

PMID- 29443809 TI - Association Between Visual Acuity and the Corneal Area Occupied by Granular Lesions, Linear Lesions, or Diffuse Haze in Patients With Granular Corneal Dystrophy Type 2. AB - PURPOSE: In granular corneal dystrophy type 2 (GCD2), corneal deposits containing fragments of transforming growth factor-beta-induced protein appear in sequence as granular lesions (GLs), linear lesions (LLs), and diffuse haze (DH). We aimed to investigate the association between visual acuity and age-related changes in lesion types in patients with GCD2. METHODS: We retrospectively evaluated the medical records and slit-lamp photographs of 533 patients (1066 eyes) with genetically confirmed GCD2 (heterozygous). Deposits were classified into GLs, LLs, and DH, after which the area occupied by each lesion type was measured. The associations between visual acuity and each lesion area were also evaluated using univariable and multivariable models. RESULTS: The area occupied by GLs increased beginning in the teen years, whereas the area occupied by DH began to increase after age 40. However, the area occupied by LLs increased until patients had reached their 40s, after which no further increases occurred. Multivariable analyses revealed no association between GLs and low visual acuity after adjusting for age and sex. Increases in the LL area were associated with lower odds for low visual acuity (adjusted odds ratio = 0.4 for the third tertile, 95% confidence interval, 0.2-0.97), whereas increases in the DH area were positively associated with low visual acuity (adjusted odds ratio = 3.3 for the third tertile of the DH area, 95% confidence interval, 1.3-8.3). CONCLUSIONS: Our findings indicated that LLs associated with GCD2 do not produce significant decreases in visual acuity, whereas DH exerts the most significant negative impact on visual acuity. Late-onset DH may be associated with the termination of LL formation. PMID- 29443811 TI - Teaching Nursing Students, Nurses, and Other Health Care Providers About Ethics Consultations.

PMID- 29443815 TI - Teaching Vaginal Hysterectomy via Simulation: Creation and Validation of the Objective Skills Assessment Tool for Simulated Vaginal Hysterectomy on a Task Trainer and Performance Among Different Levels of Trainees. AB - OBJECTIVES: The use of simulation-based education to train surgeons is widely accepted. Although many authors describe the use of an Objective Skills Assessment Test (OSAT) to assess performance of various surgical procedures, there is a paucity of research on use of this modality to evaluate vaginal surgery skills. We created a vaginal hysterectomy procedure-specific checklist (PSC) to complete the OSAT (which is composed of a PSC and a global rating scale [GRS]). The primary objective of this study is to evaluate the performance of a novel evaluation strategy for vaginal hysterectomy using an OSAT combining PSC and GRS. METHODS: This is a descriptive prospective study from a single institution. After orientation to the model, participants were filmed performing vaginal hysterectomy. A blinded grader scored each subject using the PSC and GRS. RESULTS: Medical students, residents, fellows, and attendings performed vaginal hysterectomy on a simulated model. Mean PSC and GRS scores increased significantly with surgeon level of experience (P < 0.001). Procedure-specific checklist scores significantly correlated with GRS scores (P < 0.001). CONCLUSIONS: The vaginal hysterectomy model and PSC have been studied across different surgeon levels using OSATs. Training programs should consider using this low-cost task trainer as a teaching tool. PMID- 29443816 TI - Effects of Osteotomy Lengths on the Temperature Rise of the Crestal Bone During Implant Site Preparation. AB - AIM: To compare temperatures of the crestal bone during implant site preparation for different osteotomy lengths and implant systems. METHODS: Bovine ribs were used to simulate the cortical bone of the human mandible. Three different implant systems were tested: Astra Tech, Ankylos, and XiVE. Six drills per system were performed, meaning each drilling set was used for 2 drills per 3 osteotomy lengths (8, 12, and 16 mm). Drilling force, drilling speed, drilling length, and temperature were recorded. RESULTS: Differences in the maximum temperature of the crestal bone during the first drilling for various osteotomy lengths (P = 0.021) and all implant systems (P = 0.013) were observed. A similar result was showed during the second drilling; osteotomy lengths (P = 0.014) and drilling systems (P = 0.003). Second drillings showed lower temperatures of the crestal bone with statistical differences on all measurements (P < 0.001). Astra Tech and Ankylos implant systems showed similar performance; XiVE had lower temperature and higher temperature differences between osteotomy lengths. CONCLUSIONS: Different drilling lengths contributed to the variation in temperature regardless of the implant system. Longer drills and osteotomies induced higher temperatures on the crestal bone. The maximum temperature difference between the shortest and the longest osteotomy was under 1 degrees C. Temperature above 47 degrees C that could cause bone necrosis was not recorded at any time. The XiVE system showed the best performance. PMID- 29443814 TI - Danger Signals in the ICU. AB - OBJECTIVES: Sterile and infectious critical illnesses often result in vasoplegic shock and a robust systemic inflammatory response that are similar in presentation. The innate immune system is at the center of the response to both infectious and traumatic insults. Damage-associated molecular patterns are small molecules that are released from stressed or dying cells. Damage-associated molecular patterns activate pattern recognition receptors and coordinate the leading edge of the innate immune response. This review introduces the concept of damage-associated molecular patterns and how they activate a systemic inflammatory response, specifically in trauma, neurologic injury, and infection. It also explores how, when carried to extremes, damage-associated molecular patterns may even perpetuate multisystem organ failure. DATA SOURCES: Basic and clinical studies were obtained from a PubMed search through August 2017. STUDY SELECTION: Articles considered include original articles, review articles, and conference proceedings. DATA EXTRACTION: An analysis of scientific, peer-reviewed data was performed. High quality preclinical and clinical studies adjudicated by the authors were included and summarized. DATA SYNTHESIS: Pattern recognition receptors respond to damage-associated molecular patterns and then activate inflammatory pathways. Damage-associated molecular patterns have been linked to the recruitment of sentinel leukocytes and the initiation of the inflammatory cascade. Damage-associated molecular patterns have been linked to many conditions in critical care illnesses. Preclinical models have added insight into how they may mediate distant organ dysfunction. CONCLUSIONS: Damage-associated molecular pattern activation and release is an important research for intensive care practitioners. It will add to our understanding of the phase and state of the innate immune response to an insult. Early work is encouraging. However, only with improved understanding of damage-associated molecular pattern activation and function, we can perhaps hope to target damage-associated molecular patterns as diagnostic and/or therapeutic modalities in the future.

PMID- 29443818 TI - Resection of a Giant-Cell Tumor of the Proximal Aspect of the Radius with Osteoarticular Allograft Reconstruction: A Case Report. AB - CASE: Giant-cell tumors are locally aggressive osteolytic benign tumors that are characterized by multinucleated giant cells. Recurrence rates are <=30% after curettage and <5% after resection, but reconstruction can be difficult. We describe an osteoarticular allograft reconstruction of the proximal aspect of the radius in a 23-year-old man after resection of a giant-cell tumor. CONCLUSION: Five months after surgery, the patient had satisfactory joint articulation, range of motion, and strength, with no signs of hardware or graft failure. By 17 months, there was complete osseous union. The joint remained stable at 54 months. We describe our surgical approach, which restores joint stability and minimizes recurrence. PMID- 29443819 TI - Chronic Osteomyelitis with Staphylococcus aureus Deformation in Submicron Canaliculi of Osteocytes: A Case Report. AB - CASE: A patient presenting with an infected diabetic foot ulcer and Staphylococcus aureus chronic osteomyelitis was studied to validate the clinical importance of bacterial colonization of osteocytic-canalicular networks, as we recently reported in a mouse model. We utilized transmission electron microscopy to describe the deformation of S. aureus, from round cocci to rod-shaped bacteria, in the submicron osteocytic-canalicular networks of amputated bone tissue. CONCLUSION: To our knowledge, this is the first evidence of S. aureus deformation and invasion of the osteocytic-canalicular system in human bone, which supports a new mechanism of persistence in the pathogenesis of chronic osteomyelitis. PMID- 29443820 TI - Unstable C1 Fracture Managed with Internal Fixation Using Lateral Mass Screws: A Case Report. AB - CASE: A 47-year-old woman presented with an unstable C1 fracture after falling down several stairs. She was found to have a sagittal split fracture of the right C1 lateral mass extending into the posterior arch. The fracture was treated with a direct posterior osteosynthesis of C1 using lateral mass screws. CONCLUSION: Surgical management of unstable C1 fractures has traditionally involved posterior fusion of C1 to C2 or fusion from the occiput to C2. These fusion procedures can be quite functionally limiting. Recently, direct osteosynthesis of C1 has been shown to be an effective, motion-preserving alternative. PMID- 29443821 TI - Changes in Cycling and Incidence of Overweight and Obesity among Danish Men and Women. AB - PURPOSE: Overweight and obesity are associated with increased risk of several noncommunicable diseases and are a growing public health issue. The primary purpose of the current study was to investigate incidence of overweight and obesity according to 5-yr cycling habits. The secondary purpose was to investigate incidence of remission from overweight and obesity according to 5-yr cycling habits. METHODS: We analyzed 9014 men and 8661 women without chronic disease who between 1993 and 2003 completed two assessments approximately 5 yr apart. At both assessments, participants reported habitual cycling habits. Also, body weight and waist circumference were measured by a laboratory technician at baseline and self-assessed at second examination. We computed multivariable adjusted odds ratios (OR) with 95% confidence intervals (CI) for development of and remission from abdominal and general overweight and obesity, according to 5 yr cycling habits. RESULTS: Continued cycling was associated with lower odds for incidence of abdominal (men, >102 cm; women, >88 cm) and incidence of general (body mass index >=30 kg.m) obesity; compared with no cycling, OR (95% CI) values were 0.82 (0.74-0.91) and 0.74 (0.60-0.92) for abdominal and general obesity, respectively. Also, those who initiated cycling had lower odds for incidence of abdominal obesity; OR (95% CI) was 0.85 (0.73-1.00) relative to no cycling. Although we found no evidence of remission from abdominal and general overweight and obesity according to 5-yr cycling habits, those who continued cycling had significantly larger decreases in waist circumference relative to noncyclists (beta coefficient (95% CI), -0.95 cm (-1.56 to -0.33 cm)). CONCLUSIONS: Continued cycling compared with no cycling was associated with lower odds for abdominal and general obesity. Also, late-in-life initiation of cycling was associated with lower odds for abdominal obesity relative to no cycling. PMID- 29443822 TI - Power-to-Strength Ratio Influences Performance Enhancement with Contrast Training. AB - PURPOSE: The effectiveness of contrast training (CST) for improving explosive exercise performance is modulated by various individual characteristics; however, further work is required to define these factors. METHODS: Subelite male Australian Football players (n = 22; age, 19 +/- 2 yr; body mass, 80.4 +/- 9.4 kg; one-repetition maximum [1-RM] half squat, 172 +/- 18 kg; mean +/- SD) completed two experimental trials involving two sets of squat jumps (six repetitions at 30% 1-RM) performed either alone (CTL condition) or after half squats (six repetitions at 85% 1-RM; CST condition). RESULTS: Squat jump peak power was similar between CTL and CST during set 1 (mean change: +/-90% confidence interval, 2.8% +/- 2.0%; effect size [ES]: +/-90% confidence interval, 0.13 +/- 0.09; P = 0.079) and set 2 (0.3% +/- 1.7%; ES, 0.01 +/- 0.08; P = 0.781). Peak power enhancement with CST was not related to maximal (1-RM half squat) strength (r = 0.001, P = 0.884), but was negatively correlated with both baseline peak power (r = 0.44, P < 0.001) and power-to-strength ratio (PSR); that is, the ratio between baseline peak power and 1-RM half squat strength (r = 0.65, P < 0.001). Using a median split, analyses were performed in participants with a low PSR (LPSR group; PSR = 15.4-19.1 W.kg; n = 11) or high PSR (HPSR group, PSR = 19.4-24.7 W.kg; n = 11). Peak power was enhanced with CST for the LPSR (8.1% +/- 3.9%; ES, 0.44 +/- 0.21; P = 0.004) but not HPSR (-2.1% +/- 1.3%; ES, -0.14 +/- 0.09; P = 0.010) groups. CONCLUSION: The PSR appears to influence the effectiveness of CST, with performance enhancement more likely in those with a lower PSR. PMID- 29443823 TI - Aerobic Training Improves Quality of Life in Women with Polycystic Ovary Syndrome. AB - PURPOSE: To investigate the effects of a supervised aerobic exercise training intervention on health-related quality of life (HRQL), cardiorespiratory fitness, cardiometabolic profile, and affective response in overweight/obese women with polycystic ovary syndrome (PCOS). METHODS: Twenty-seven overweight/obese inactive women with PCOS (body mass index, >= 25 kg.m; age 18 to 34 yr) were allocated into an exercise group (n = 14) and a control group (n = 13). Progressive aerobic exercise training was performed three times per week (~150 min.wk) over 16 wk. Cardiorespiratory fitness, HRQL, and cardiometabolic profile were evaluated before and after the intervention. Affective response (i.e., feeling of pleasure/displeasure) was evaluated during the exercise sessions. RESULTS: The exercise group improved 21% +/- 12% of cardiorespiratory fitness (P < 0.001) and HRQL in the following domains: physical functioning, general health, and mental health (P < 0.05). Moreover, the exercise group decreased body mass index, waist circumference, systolic and diastolic blood pressure, and total cholesterol level (P < 0.05). The affective response varied from "good" to "fairly good" (i.e., positive affective response) in an exercise intensity-dependent manner during the exercise training sessions. CONCLUSIONS: Progressive aerobic exercise training improved HRQL, cardiorespiratory fitness, and cardiometabolic profile of overweight/obese women with PCOS. Moreover, the participants reported the exercise training sessions as pleasant over the intervention. These results reinforce the importance of supervised exercise training as a therapeutic approach for overweight/obese women with PCOS.

AB - PURPOSE: This study aimed to improve estimates of sitting time from hip-worn accelerometers used in large cohort studies by using machine learning methods developed on free-living activPAL data. METHODS: Thirty breast cancer survivors concurrently wore a hip-worn accelerometer and a thigh-worn activPAL for 7 d. A random forest classifier, trained on the activPAL data, was used to detect sitting, standing, and sit-stand transitions in 5-s windows in the hip-worn accelerometer. The classifier estimates were compared with the standard accelerometer cut point, and significant differences across different bout lengths were investigated using mixed-effect models. RESULTS: Overall, the algorithm predicted the postures with moderate accuracy (stepping, 77%; standing, 63%; sitting, 67%; sit-to-stand, 52%; and stand-to-sit, 51%). Daily level analyses indicated that errors in transition estimates were only occurring during sitting bouts of 2 min or less. The standard cut point was significantly different from the activPAL across all bout lengths, overestimating short bouts and underestimating long bouts. CONCLUSIONS: This is among the first algorithms for sitting and standing for hip-worn accelerometer data to be trained from entirely free-living activPAL data. The new algorithm detected prolonged sitting, which has been shown to be the most detrimental to health. Further validation and training in larger cohorts is warranted.

AB - BACKGROUND: To evaluate the effect of antenatal influenza vaccination on all cause severe infant pneumonia, we performed pooled analysis of 3 randomized controlled trials conducted in Nepal, Mali and South Africa. METHODS: The trials were coordinated from the planning phase. The follow-up period was 0-6 months postpartum in Nepal and Mali and 0-24 weeks in South Africa. Pregnant women with gestational age 17-34 weeks in Nepal, >=28 weeks in Mali and 20-36 weeks in South Africa were enrolled. Trivalent inactivated influenza vaccine (IIV) was compared with either saline placebo (Nepal and South Africa) or quadrivalent meningococcal conjugate vaccine (Mali). In South Africa, cases were hospitalized and were therefore considered to have severe pneumonia. In Nepal and Mali, severe infant pneumonia diagnosis was based on the WHO Integrated Management of Childhood Illness definition. RESULTS: A total of 10,002 mothers and 9801 live-born eligible infants were included in the present analysis. There was a 31% lower incidence rate of severe pneumonia in the IIV group compared with the control group in Nepal [incidence rate ratio (IRR): 0.69; 95% CI: 0.50-0.94; ]. In South Africa, there was a 43% lower incidence rate of severe pneumonia in the IIV group versus the control group (IRR: 0.57; 95% CI: 0.33-1.0). There was no difference in incidence rates between the IIV group and the control group in Mali. Overall, incidence rate of severe pneumonia was 20% lower in the IIV group compared with the control group (IRR: 0.80; 95% CI: 0.66-0.99; P = 0.04). Protection was highest in the high influenza circulation period (IRR: 0.44; 95% CI: 0.23-0.84). CONCLUSIONS: Maternal influenza immunization may reduce severe pneumonia episodes among infants-particularly those too young to be completely vaccinated against Streptococcus pneumoniae and influenza. PMID- 29443826 TI - Higher Risk of Posttransplant Liver Graft Failure in Male Recipients of Female Donor Grafts Might Not Be Due to Anastomotic Size Disparity. AB - BACKGROUND: Posttransplant liver graft failure occurs most often in male recipients of livers from female donors. The respective role of donor sex itself and the size disparity in graft vessels/bile ducts according to donor sex are unclear. Thus, we aimed to evaluate the importance of donor sex with adjustment for anastomotic size disparity between female and male donor grafts. METHODS: A total of 309 male patients without hepatic tumors who underwent living donor liver transplantation were analyzed (109 female donors and 200 male donors). The primary outcome was posttransplant graft failure (ie, retransplantation or death). Survival analysis was performed using the Cox model. Analyzed anastomosis related factors comprised graft weight, number and size of hepatic vessels/bile ducts, and anastomosis techniques. RESULTS: Graft failure probabilities at 1, 6, 12, 24, and 60 months posttransplantation were 9.1%, 19.5%, 20.2%, 23.0%, and 27.0%, respectively, with female donors and 2.0%, 5.5%, 8.1%, 10.1%, and 13.5% with male donors (hazards ratio [HR], 2.29; 95% confidence interval [CI], 1.35 3.88; P = 0.002). Multivariable analysis confirmed the significance of donor sex (HR, 2.30; 95% CI, 1.14-4.67; P = 0.021) after adjustment for anastomosis-related factors. All analyzed anastomosis-related factors showed no significant association with graft failure, although size of the graft hepatic artery showed marginal significance (HR, 0.50; 95% CI, 0.25-1.01; P = 0.053). The significance of donor sex was lost when donor was older than 36 to 40 years (age of poor ovarian reserve and the end of female fertility). Our institutional pediatric recipient cohort validated the inferiority of female-to-male donation. CONCLUSIONS: Donor sex appears to be an independent factor modulating graft failure risk in male liver transplant recipients. PMID- 29443828 TI - Fat Grafting for Facial Rejuvenation and Contouring: A Rationalized Approach. AB - The clinical outcome after fat grafting for facial rejuvenation and contouring can be less optimal because lack of standardized techniques is performed by the surgeon for the procedure. In this review, the author has tried to provide a rationalized approach to fat grafting for facial rejuvenation and contouring. The preferred donor sites include low abdomen and inner thigh especially in younger patients. Fat grafts should be harvested with low negative pressure via syringe liposuction technique to ensure the integrity as well as the optimal level of cellular function. Fat grafts should be processed with proper centrifugation that can reliably produce purified fat and concentrated growth factors and adipose derived stem cells, all of which are beneficial to improve graft survival. Fat grafts should be placed after certain principles with gentle injection of small amount during the withdraw phase of each pass in multiple tissue planes and levels with multiple passes to ensure maximal contact of graft with vascularized tissue in the recipient site. The approach described in this review is supported by the most recent scientific studies and thus can likely provide a more predictable long-lasting result if performed properly. PMID- 29443827 TI - A Comparison of HLA Molecular Mismatch Methods to Determine HLA Immunogenicity. AB - BACKGROUND: Antibody-mediated rejection is a major cause of premature graft loss in kidney transplantation. Multiple scoring systems are available to assess the HLA mismatch between donors and recipients at the molecular level; however, their correlation with the development of de novo donor-specific antibody (dnDSA) has not been compared in recipients on active immunosuppression. METHODS: HLA DRbeta1/3/4/5/DQalpha1beta1 molecular mismatch was determined using eplet analysis, amino acid mismatch, and electrostatic mismatch for 596 renal transplant recipients and correlated with HLA-DR/DQ dnDSA development. The molecular mismatch scores were evaluated in multivariate models of posttransplant dnDSA-free survival. RESULTS: Eplet mismatch correlated with amino acid mismatch and electrostatic mismatch (R = 0.85-0.96). HLA-DR dnDSA-free survival correlated with HLA-DR eplet mismatch (hazards ratio [HR], 2.50 per 10 eplets mismatched; P < 0.0001), amino acid mismatch (HR, 1.49 per 10 amino acids mismatched; P < 0.0001), and electrostatic mismatch (HR, 1.23 per 10 units mismatched; P < 0.0001). HLA-DQ dnDSA-free survival correlated with HLA-DQ eplet mismatch (HR, 1.98 per 10 eplets mismatched; P < 0.0001), amino acid mismatch (HR, 1.24 per 10 amino acids mismatched; P < 0.0001), and electrostatic mismatch (HR, 1.14 per 10 units mismatched; P < 0.0001). All 3 methods were significant multivariate correlates of dnDSA development after adjustment for recipient age, baseline immunosuppression, and nonadherence. CONCLUSIONS: HLA molecular mismatch represents a precise method of alloimmune risk assessment for renal transplant patients. The method used to determine the molecular mismatch is likely to be driven by familiarity and ease of use as highly correlated results are produced by each method.

PMID- 29443831 TI - Assessment of the Effect of Autograft Orientation on Peripheral Nerve Regeneration Using Diffusion Tensor Imaging. AB - PURPOSE: Given no definite consensus on the accepted autograft orientation during peripheral nerve injury repair, we compare outcomes between reverse and normally oriented autografts using an advanced magnetic resonance imaging technique, diffusion tensor imaging. METHODS: Thirty-six female Sprague-Dawley rats were divided into 3 groups: sham-left sciatic nerve isolation without injury, reverse autograft-10-mm cut left sciatic nerve segment reoriented 180 degrees and used to coapt the proximal and distal stumps, or normally oriented autograft-10-mm cut nerve segment kept in its normal orientation for coaptation. Animals underwent sciatic functional index and foot fault behavior studies at 72 hours, and then weekly. At 6 weeks, axons proximal, within, and distal to the autograft were evaluated using diffusion tensor imaging and choline acetyltransferase motor staining for immunohistochemistry. Toluidine blue staining of 1-MUm sections was used to assess axon count, density, and diameter. Bilateral gastrocnemius/soleus muscle weights were compared to obtain a net wet weight. Comparison of the groups was performed using Mann-Whiney U or Kruskal-Wallis H tests to determine significance. RESULTS: Diffusion tensor imaging findings including fractional anisotropy, radial diffusivity, and axial diffusivity were similar between reverse and normally oriented autografts. Diffusion tensor imaging tractography demonstrated proximodistal nerve regeneration in both autograft groups. Motor axon counts proximal, within, and distal to the autografts were similar. Likewise, axon count, density, and diameter were similar between the autograft groups. Muscle net weight at 6 weeks and behavioral outcomes (sciatic functional index and foot fault) at any tested time point were also similar between reverse and normally oriented autografts. CONCLUSIONS: Diffusion tensor imaging may be a useful assessment tool for peripheral nerve regeneration. Reversing nerve autograft polarity did not demonstrate to have an influence on functional or regenerative outcomes. PMID- 29443832 TI - One-Barrel Microsurgical Fibula Flap for Reconstruction of Large Defects of the Femur. AB - Various methods for reconstructing large femur bone defects after tumor resection have been introduced. In this study, we reviewed the clinical outcomes of using a 1-barrel free vascularized fibular graft (FVFG) protected by a lateral locking plate for large femoral defects not involving the knee joint.Between August 2007 and August 2013, we treated 7 patients with large femoral bone defects after tumor resection. The mean age of the patients was 19 years (range, 12-36 years), and 3 were women. All defects were free of infection before the procedure. Femoral bone defects were reconstructed using a 1-barrel FVFG protected by a lateral locking plate. The mean bone defect size was 10.5 cm (range, 6-16 cm). We reviewed clinical outcomes at the last follow-up.All patients survived beyond the last follow-up; the mean follow-up period was 54 months (range, 26-100 months). Two patients sustained stress fractures of the FVFG, but the lateral locking plate protected the fractured graft until in situ bone healing obtained. Mean time to bone union of both host-graft junctions was 24 months (range, 18-31 months). The mean Musculoskeletal Tumor Society score (%) was 85.8% (range, 80 95%).A 1-barrel FVFG protected by a lateral locking plate maintained a stable graft-host bone construct, successfully leading to bone healing, even in cases of stress fractures of the graft, and appears to be a good option for large femur bone defects. PMID- 29443834 TI - Does 2-Stage Implant-Based Breast Reconstruction Allow for a Larger Volume of the Definite Implant Compared With 1-Stage Reconstruction? AB - INTRODUCTION: Breast reconstruction using implants is still the main breast reconstruction technique worldwide. Current debate within implant-based breast reconstruction is whether to perform a 1-stage (direct implant) or 2-stage (tissue expander/implant) reconstruction. Volume differences between a woman's native breast and changes in volume after breast reconstruction might be an important factor for a patient's choice between these types of reconstruction. Three-dimensional imaging facilitates objective breast volume estimates. The goal of this study was to investigate differences between the patient's natural breast and the volume after completed breast reconstruction. One- and two-stage implant based breast reconstruction techniques were compared. Finally, it was assessed whether patient satisfaction is causally related with the final breast volume after reconstruction. METHODS AND RESULTS: A total of 38 patients were included in the study, including 35 two-stage breast reconstructions and 27 one-stage reconstructions. Preoperative and postoperative 3-dimensional images of the breast with the Vectra XT Imaging system were taken. Volume analysis was performed to estimate the patient's native breast volume. Implant size were derived from the operation report. A mean volume reduction for the 1-stage reconstruction group was found -1 mL, whereas an increase of +80 mL was found in the 2-stage reconstruction group (P < 0.005). Patient satisfaction related to volume outcome was not significantly different between both groups, using the Breast-Q questionnaire. CONCLUSIONS: This study shows that a 2-stage breast reconstruction has the potential of an increased breast volume compared with a similar breast volume in 1-stage reconstruction. PMID- 29443833 TI - Experimental Study on Effects of Adipose-Derived Stem Cell-Seeded Silk Fibroin Chitosan Film on Wound Healing of a Diabetic Rat Model. AB - BACKGROUND: Wound healing is a complex process that relies on growth factors and stimulation of angiogenesis. Tissue engineering materials composed of adipose derived stem cells (ADSCs) and silk fibroin (SF)/chitosan (CS) may be able to solve this problem. The aim of this study was to investigate the wound-healing potential of ADSC-seeded SF/CS in streptozotocin-induced diabetic rats. MATERIALS AND METHODS: Thirty-six male Sprague-Dawley rats were purchased and randomly assigned into 3 groups: a control group (no graft), a group treated with SF/CS film graft, and a group treated with ADSC-seeded SF/CS graft. The number of animals in each group was 12. Diabetes was induced by an intraperitoneal injection of streptozotocin. A cutaneous wound was incised at the dorsal region of all the experimental animals. The ADSCs were labeled with CM-Dil fluorescent staining. Wound healing was assessed for all animal groups by observing the rate of wound closure and hematoxylin and eosin staining. The expression of epidermal growth factor, transforming growth factor-beta, and vascular endothelial growth factor at the wound sites was studied by enzyme-linked immunosorbent assay to evaluate the effect of growth factors secreted by ADSCs. The differentiation of ADSCs was analyzed by immunofluorescence staining. RESULTS: The ADSC-seeded SF/CS film treatment significantly increased the rates of wound closure in treated animals, and hence wound healing was drastically enhanced for ADSC-SF/CS treatment groups compared with control groups and SF/CS film treatment group. Histological observations showed the condition of wound healing. Enzyme-linked immunosorbent assay and immunofluorescence staining observations showed the secretion and differentiation of ADSCs, respectively. CONCLUSIONS: Our analyses clearly suggested that it is feasible and effective to enhance wound healing in a diabetic rat model with ADSC-seeded SF/CS film. PMID- 29443835 TI - Venous Thromboembolism Incidence After Craniofacial Surgery. AB - INTRODUCTION: Current protocols for venous thromboembolism (VTE) prophylaxis after craniofacial surgery (CFS) vary widely with substantial disagreements in both indications and managements. An evidence-based approach to this issue requires the following: the incidence of postoperative VTE, comorbidities associated with coagulopathy, risk reduction after VTE prophylaxis, and complications attributable to prophylaxis. This study addresses the first two. DESIGN: Retrospective cross-sectional study. METHODS: Discharge data from 64,170 patients undergoing CFS between 2008 and 2013 extracted from the Healthcare Cost and Utilization Project Nationwide Inpatient Sample were analyzed. The outcome measures extracted were: deep venous thrombosis, pulmonary embolism, demographic data, common comorbidities, length of stay, total cost, and discharge outcome. RESULTS: Diagnoses of deep venous thrombosis or pulmonary embolism, collectively classified as VTE, were observed in 355 (0.55%) of 64,170 patients discharged after CFS. Other surgeries exhibited a VTE rate of 1.17%. Men exhibited nearly double the incidence of VTE relative to women (0.69% compared with 0.37% respectively, P < 0.001), and the risk factors of adulthood, advanced age, cardiovascular disease, obesity, and malignancy were associated with increased VTE incidence with odds ratios of 9.93, 3.66, 1.80, 2.02, and 2.02, respectively (P < 0.005). Tobacco use did not exhibit any significant association (odds ratio, 0.94; P = 0.679). Afflicted patients experienced 4.60 times longer hospital stays averaging 23.8 days (95% confidence interval, 21.4-26.2; P < 0.001) compared the average of 5.2 days experienced by CFS patients without VTE. They incurred an average cost of US $298,228 (95% confidence interval, 262,726 to 333,731; P < 0.001) which was 4.17 times the US $72,376 expense of treating other CFS patients. The likelihood for a CFS patient to experience a poor outcome at the time of discharge was 54.6% higher after VTE. CONCLUSIONS: The risk of postoperative VTE after CFS is significantly increased in adults, patients with advanced age, cardiovascular disease, obesity, and malignancy. However even in those high-risk cases, postoperative VTE incidence remains relatively low after CFS. These findings in conjunction with further study regarding the risk associated with the addition of VTE chemoprophylaxis compared against mechanical VTE prophylaxis, such as sequential pneumatic compression stockings, may determine whether routine use of VTE chemoprophylaxis is appropriate.

PMID- 29443837 TI - Editorial: Orthopaedic Heroes-Here are Mine, Who are Yours? PMID- 29443839 TI - How Common-and How Serious- Is Clostridium difficile Colitis After Geriatric Hip Fracture? Findings from the NSQIP Dataset. AB - BACKGROUND: Patients with geriatric hip fractures may be at increased risk for postoperative Clostridium difficile colitis, which can cause severe morbidity and can influence hospital quality metrics. However, to our knowledge, no large database study has calculated the incidence of, factors associated with, and effect of C. difficile colitis on geriatric patients undergoing hip fracture surgery. QUESTIONS/PURPOSES: To use a large national database with in-hospital and postdischarge data (National Surgical Quality Improvement Program [NSQIP(r)]) to (1) determine the incidence and timing of C. difficile colitis in geriatric patients who underwent surgery for hip fracture, (2) identify preoperative and postoperative factors associated with the development of C. difficile colitis in these patients, and (3) test for an association between C. difficile colitis and postoperative length of stay, 30-day readmission, and 30-day mortality. PATIENTS AND METHODS: This is a retrospective study. Patients who were 65 years or older who underwent hip fracture surgery were identified in the 2015 NSQIP database. The primary outcome was a diagnosis of C. difficile colitis during the 30-day postoperative period. Preoperative and procedural factors were tested for association with the development of C. difficile colitis through a backward stepwise multivariate model. Perioperative antibiotic type and duration were not included in the model, as this information was not recorded in the NSQIP. The association between C. difficile colitis and postoperative length of stay, 30-day readmission, and 30-day mortality were tested through multivariate regressions, which adjusted for preoperative and procedural characteristics such as age, comorbidities, and surgical procedure. A total of 6928 patients who were 65 years or older and underwent hip fracture surgery were identified. RESULTS: The incidence of postoperative C. difficile colitis was 1.05% (95% CI, 0.81%-1.29%; 73 of 6928 patients). Of patients who had C. difficile colitis develop, 64% (47 of 73 patients) were diagnosed postdischarge and 79% (58 of 73 patients) did not have a preceding infectious diagnosis. Preoperative factors identifiable before surgery that were associated with the development of C. difficile colitis included admission from any type of chronic care facility (versus admitted from home; relative risk [RR] = 1.98; 95% CI, 1.11-3.55; p = 0.027), current smoker within 1 year (RR = 1.95; 95% CI, 1.03-3.69; p = 0.041), and preoperative anemia (RR = 1.76; 95% CI, 1.07-2.92; p = 0.027). Patients who had pneumonia (RR = 2.58; 95% CI, 1.20-5.53; p = 0.015), sepsis (RR = 4.20; 95% CI, 1.27-13.82; p = 0.018), or "any infection" (RR = 2.26; 95% CI, 1.26-4.03; p = 0.006) develop after hip fracture were more likely to have C. difficile colitis develop. Development of C. difficile colitis was associated with greater postoperative length of stay (22 versus 5 days; p < 0.001), 30-day readmission (RR = 3.41; 95% CI, 2.17-5.36; p < 0.001), and 30-day mortality (15% [11 of 73 patients] versus 6% [439 of 6855 patients]; RR = 2.16; 95% CI, 1.22-3.80; p = 0.008). CONCLUSIONS: C. difficile colitis is a serious infection after hip fracture surgery in geriatric patients that is associated with 15% mortality. Patients at high risk, such as those admitted from any type of chronic care facility, those who had preoperative anemia, and current smokers within 1 year, should be targeted with preventative measures. From previous studies, these measures include enforcing strict hand hygiene with soap and water (not alcohol sanitizers) if a provider is caring for patients at high risk and those who are C. difficile-positive. Further, other studies have shown that certain antibiotics, such as fluoroquinolones and cephalosporins, can predispose patients to C. difficile colitis. These medications perhaps should be avoided when prescribing prophylactic antibiotics or managing infections in patients at high risk. Future prospective studies should aim to determine the best prophylactic antibiotic regimens, probiotic formula, and discharge timing that minimize postoperative C. difficile colitis in patients with hip fractures.

PMID- 29443845 TI - Raising the Joint Line in TKA is Associated With Mid-flexion Laxity: A Study in Cadaver Knees. AB - BACKGROUND: In a typical osteoarthritic knee with varus deformity, distal femoral resection based off the worn medial femoral condyle may result in an elevated joint line. In a setting of fixed flexion contracture, the surgeon may choose to resect additional distal femur to obtain extension, thus purposefully raising the joint line. However, the biomechanical effect of raising the joint line is not well recognized. QUESTIONS/PURPOSES: (1) What is the effect of the level of the medial joint line (restored versus raised) on coronal plane stability of a TKA? (2) Does coronal alignment technique (mechanical axis versus kinematic technique) affect coronal plane stability of the knee? (3) Can the effect of medial joint line elevation on coronal plane laxity be predicted by an analytical model? METHODS: A TKA prosthesis was implanted in 10 fresh frozen nonarthritic cadaveric knees with restoration of the medial joint line at its original level (TKA0). Coronal plane stability was measured at 0 degrees , 30 degrees , 60 degrees , 90 degrees , and 120 degrees flexion using a navigation system while applying an instrumented 9.8-Nm varus and valgus force moment. The joint line then was raised in two steps by recutting the distal and posterior femur by an extra 2 mm (TKA2) and 4 mm (TKA4), downsizing the femoral component and, respectively, adding a 2- and a 4-mm thicker insert. This was done with meticulous protection of the ligaments to avoid damage. Second, a simplified two-dimensional analytical model of the superficial medial collateral ligament (MCL) length based on a single flexion-extension axis was developed. The effect of raising the joint line on the length of the superficial MCL was simulated. RESULTS: Despite that at 0 degrees (2.2 degrees +/- 1.5 degrees versus 2.3 degrees +/- 1.1 degrees versus 2.5 degrees +/- 1.1 degrees ; p = 0.85) and 90 degrees (7.5 degrees +/- 1.9 degrees versus 9.0 degrees +/- 3.1 degrees versus 9.0 degrees +/- 3.5 degrees ; p = 0.66), there was no difference in coronal plane laxity between the TKA0, TKA2, and TKA4 positions, increased laxity at 30 degrees (4.8 degrees +/- 1.9 degrees versus 7.9 degrees +/- 2.3 degrees versus 10.2 degrees +/- 2.0 degrees ; p < 0.001) and 60 degrees (5.7 degrees +/- 2.7 degrees versus 8.8 degrees +/- 2.9 degrees versus 11.3 degrees +/- 2.9 degrees ; p < 0.001) was observed when the medial joint line was raised 2 and 4 mm. At 30 degrees , this corresponds to an average increase of 64% (3.1 degrees ; p < 0.01) in mid-flexion laxity with a 2-mm raised joint line and a 111% (5.4 degrees ; p < 0.01) increase with a 4-mm raised joint line compared with the 9-mm baseline resection. No differences in coronal alignment were found between the knees implanted with kinematic alignment versus mechanical alignment at any flexion angle. The analytical model was consistent with the cadaveric findings and showed lengthening of the superficial MCL in mid-flexion. CONCLUSIONS: Despite a well balanced knee in full extension and at 90 degrees flexion, increased mid-flexion laxity in the coronal plane was evident in the specimens where the joint line was raised. CLINICAL RELEVANCE: When recutting the distal and posterior femur and downsizing the femoral component, surgeons should be aware that this action might increase the laxity in mid-flexion, even if the knee is stable at 0 degrees and 90 degrees .

PMID- 29443850 TI - Does an Algorithmic Approach to Using Brachytherapy and External Beam Radiation Result in Good Function, Local Control Rates, and Low Morbidity in Patients With Extremity Soft Tissue Sarcoma? AB - BACKGROUND: High-dose-rate brachytherapy (HDR-BT) and external-beam radiation therapy (EBRT) are two modalities used in the treatment of soft tissue sarcoma. Previous work at our institution showed early complications and outcomes for patients treated with HDR-BT, EBRT, or a combination of both radiation therapy modalities. As the general indications for each of these approaches to radiation therapy differ, it is important to evaluate the use of each in an algorithmic way, reflecting how they are used in contemporary practice at sites that use these treatments. QUESTION/PURPOSES: (1) To determine the proportions of intermediate- and long-term complications associated with the use of brachytherapy in the treatment of primary high-grade extremity soft tissue sarcomas; (2), to characterize the long-term morbidity of the three radiation treatment groups using the Radiation Therapy Oncology Group/ European Organization for Research and Treatment of Cancer (RTOG/EORTC) Late Radiation Morbidity Scoring Scheme; (3) to determine whether treatment with HDR-BT, EBRT, and HDR-BT+EBRT therapy, in combination with limb-salvage surgery, results in acceptable local control in this high-risk group of sarcomas. METHODS: We retrospectively studied data from 171 patients with a diagnosis of high-grade extremity soft tissue sarcoma treated with limb-sparing surgery and radiation therapy between 1990 and 2012 at our institution, with a mean followup of 72 months. Of the 171 patients, 33 (20%) were treated with HDR-BT, 128 (75%) with EBRT, and 10 (6%) with HDR-BT+EBRT. We excluded 265 patients with soft tissue sarcomas owing to axial tumor location, previous radiation to the affected extremity, incomplete patient records, patients receiving primary amputation, recurrent tumors, pediatric patients, low- and intermediate-grade tumors, and rhabdoid histology. Fifteen patients (9%) were lost to followup for any reason including died of disease or other causes during the first 12 months postoperatively. This included four patients who received HDR-BT (12%), 11 who received EBRT (9%), and none who received HDR-BT+EBRT (0%) with less than 12 months followup. Determination of radiation therapy technique for each patient was individualized in a multidisciplinary forum of sarcoma specialists. Anticipated close or positive surgical margins and a low likelihood of complex soft tissue procedures were factors that encouraged use of brachytherapy, whereas the anticipated need for secondary procedures and/or soft tissue coverage encouraged use of EBRT alone. Combination therapy was used when the treatment volume exceeded the treatment field of the brachytherapy catheters or when the catheters were used to boost a close or positive surgical margin. Local recurrence, complications, and morbidity outcomes scores (RTOG) were calculated based on chart review. Between-group comparisons pertaining to the proportion of patients experiencing complications, morbidity outcomes scores, and local recurrence rates were not performed because of dissimilarities among the patients in each group at baseline. RESULTS: The HDR-BT treatment group showed a high incidence of intermediate-term complications, with the three most common being: deep infection (33%, 11 of 33); dehiscence and delayed wound healing (24%, eight of 33); and seroma and hematoma (21%, seven of 33). The EBRT group showed a high incidence of intermediate- and long-term complications with the three most common being: chronic radiation dermatitis (35%, 45 of 128); fibrosis (27%, 35 of 128); and chronic pain and neuritis (13%, 16 of 128). The RTOG scores for each treatment group were: HDR-BT 0.8 +/- SD 1.2; EBRT 1.9 +/- 2.0; and HDR-BT+EBRT 1.7 +/- 1.7. Overall, 142 of 169 (84%) patients were free from local recurrence: 27 (82%) in the HDR-BT group, 108 (86%) in the EBRT group, and seven (70%) in the combination therapy group. CONCLUSIONS: In this single-institution study, an algorithmic approach to using HDR-BT and EBRT in the treatment of patients with high-grade soft tissue sarcomas can yield acceptable complication rates, good morbidity outcome scores, and a high degree of local control. Based on these results, we believe HDR-BT is best for patients with an anticipated close margin, a positive surgical margin, and for patients who are unlikely to receive a complex soft tissue procedure. Conversely, if a secondary procedure and/or soft tissue coverage are likely to be used, EBRT alone may be reasonable. Finally, combination therapy might be considered when the treatment volume exceeded the treatment field capacity for HDR-BT or when the catheters were used to boost a close or positive surgical margin.

PMID- 29443852 TI - Chlorhexidine Antiseptic Irrigation Eradicates Staphylococcus epidermidis From Biofilm: An In Vitro Study. AB - BACKGROUND: Antiseptic and antibacterial solutions used for intraoperative irrigation are intended to kill bacteria and thereby decrease the incidence of surgical site infections. It is unknown if the concentrations and exposure times of irrigation solutions commonly used for prophylaxis in clean cases (povidone iodine 0.35% for 3 minutes) are effective against bacteria in biofilm that are present in implant infections. Currently, povidone-iodine (0.35%), chlorhexidine (0.05%), sodium hypochlorite (0.125%), and triple antibacterial solution are all being used off-label for wound irrigation after surgical debridement for orthopaedic infections. QUESTIONS/PURPOSES: Do commonly used antibacterials and antiseptics kill bacteria in established biofilm at clinically relevant concentrations and exposure times? METHODS: Staphylococcus epidermidis (ATCC#35984) biofilms were exposed to chlorhexidine (0.025%, 0.05%, and 0.1%), povidone-iodine (0.35%, 1.0%, 3.5%, and 10%), sodium hypochlorite (0.125%, 0.25%, and 0.5%,), and triple antibacterial solution (bacitracin 50,000 U/L, gentamicin 80 mg/L, and polymyxin 500,000 U/L) for 1, 5, and 10 minutes in triplicate. Surviving bacteria were detected by 21-day subculture. Failure to eradicate all bacteria in any of the three replicates was considered to be "not effective" for that respective solution, concentration, and exposure time. RESULTS: Chlorhexidine 0.05% and 0.1% at all three exposure times, povidone-iodine 10% at all three exposure times, and povidone-iodine 3.5% at 10 minutes only were effective at eradicating S epidermidis from biofilm. All concentrations and all exposure times of sodium hypochlorite and triple antibacterial solution were not effective. CONCLUSIONS: Chlorhexidine is capable of eradicating S epidermidis from biofilm in vitro in clinically relevant concentrations and exposure times. Povidone-iodine at commonly used concentrations and exposure times, sodium hypochlorite, and triple antibacterial solutions are not. CLINICAL RELEVANCE: This in vitro study suggests that chlorhexidine may be a more effective irrigation solution for S epidermidis in biofilm than other commonly used solutions, such as povidone-iodine, Dakin's solution, and triple antibiotic solution. Clinical outcomes should be studied to determine the most effective antiseptic agent, concentration, and exposure time when intraoperative irrigation is used in the presence of biofilm.

PMID- 29443854 TI - Universal screening for intimate partner and sexual violence in trauma patients What about the men? An Eastern Association for the Surgery of Trauma Multicenter Trial. AB - BACKGROUND: A recent Eastern Association for the Surgery of Trauma-supported multicenter trial demonstrated a similar rate of intimate partner and sexual violence (IPSV) between male and female trauma patients, regardless of mechanism. Our objective was to perform a subgroup analysis of our affected male cohort because this remains an understudied group in the trauma literature. METHODS: We conducted a recent Eastern Association for the Surgery of Trauma-supported, cross sectional, multicenter trial over one year (March 2015 to April 2016) involving four Level I trauma centers throughout the United States. We performed universal screening of adult trauma patients using the validated Hurt, Insult, Threaten, Scream and sexual violence screening surveys. Risk factors for male patients were identified. chi Test compared categorical variables with significance at p values less than 0.05. Parametric data are presented as mean +/- standard deviation. RESULTS: A total of 2,034 trauma patients were screened, of which 1,281 (63%) were men. Of this cohort, 119 (9.3%) men screened positive for intimate partner violence, 14.1% for IPSV, and 6.5% for sexual violence. On categorical analysis of the Hurt, Insult, Threaten, Scream screen, the proportion of men that were physically hurt was 4.8% compared to 4.3% for women (p = 0.896). A total of 4.8% of men screened positive for both IPSV. The total proportion of men who presented with any history of intimate partner violence, sexual violence, or both (IPSV) was 15.8%. More men affected by penetrating trauma screened positive for IPSV (p < 0.00001). The IPSV positivity in men was associated with mental illness, substance abuse, and trauma recidivism. CONCLUSION: One of every 20 men that present to trauma centers is a survivor of both IPSV, with one of every six men experiencing some form of violence. Men are at similar risk for physical abuse as women when this intimate partner violence occurs. The IPSV is associated with penetrating trauma in men. Support programs for this population may potentially impact associated mental illness, substance abuse, trauma recidivism, and even societal-level violence.

AB - BACKGROUND: While studies show that single-dose remote ischemic conditioning (RIC) improves outcomes, the effect of continuous (daily) RIC is unknown. Thus, we aimed to investigate the role of continuous RIC on cognitive and motor function following traumatic brain injury (TBI). METHODS: We subjected 24 male C57BL mice to a cortical-controlled TBI. Two hours after TBI, the animals were randomly allocated to the RIC group (n = 12) or the sham group (n = 12). Remote ischemic conditioning was induced by noninvasive external compression of the hind limb using an occlusive band (six 4-minute cycles/24 hours) for six consecutive days. Before TBI, a baseline rotarod test and novel object recognition were performed. Post-TBI rotarod and novel object recognition tests were performed on Days 1 to 5, 7, 14, and 21. After the animals were sacrificed on Day 21, brain sections were analyzed using hematoxylin and eosin and glial fibrillary acidic protein staining to evaluate the hippocampal CA1 area for neuronal injury. RESULTS: Both the RIC and sham groups had lower latency to fall compared with the baseline post-TBI. The RIC animals had a higher latency to fall compared with the sham animals at all time points, statistically significant after Day 3, until Day 21 post-TBI. Both the RIC and sham groups had lower recognition index compared with the baseline post-TBI. The RIC animals had a significantly higher recognition index than the sham animals after Day 1, until Day 21 post-TBI. Hematoxylin and eosin and glial fibrillary acidic protein staining of the brain samples of the sham group revealed that more neurons in the hippocampal CA1 area appeared shrunken with eosinophilic cytoplasm and pyknotic nuclei compared with the brain samples of the RIC group. CONCLUSION: Postinjury continuous RIC resulted in improved cognitive functions and motor coordination in a mouse model of moderate TBI. Further studies are required to determine optimum dosage and frequency of this novel therapy to maximize its beneficial effects following TBI. PMID- 29443856 TI - Complications in tube thoracostomy: Systematic review and meta-analysis. AB - BACKGROUND: Tube thoracostomy (TT) complications and their reported rates are highly variable (1-40%) and inconsistently classified. Consistent TT complication classification must be applied to compare reported literature to standardize TT placement. We aim to determine the overall TT-related complication rates in patients receiving TT for traumatic indications using uniform definitions. METHODS: Systematic review and meta-analysis was performed assessing TT-related complications. Comprehensive search of several databases (1975-2015) was conducted. We included studies that reported on bedside TT insertion (>=22 Fr) in trauma patients. Data were abstracted from eligible articles by independent reviewers with discrepancies reconciled by a third. Analyses were based on complication category subtypes: insertional, positional, removal, infection/immunologic/education, and malfunction. RESULTS: Database search resulted in 478 studies; after applying criteria 29 studies were analyzed representing 4,981 TTs. Injury mechanisms included blunt 60% (49-71), stab 27% (17-34), and gunshot 13% (7.8-10). Overall, median complication rate was 19% (95% confidence interval, 14-24.3). Complication subtypes included insertional (15.3%), positional (53.1%), removal (16.2%), infection/immunologic (14.8%), and malfunction (0.6%). Complication rates did not change significantly over time for insertional, immunologic, or removal p = 0.8. Over time, there was a decrease in infectious TT-related complications as well as an increase in positional TT complications. CONCLUSION: Generation of evidence-based approaches to improve TT insertion outcomes is difficult because a variety of complication classifications has been used. This meta-analysis of complications after TT insertion in trauma patients suggests that complications have not changed over time remaining stable at 19% over the past three decades.

PMID- 29443857 TI - The FAST Exam Can Reliably Identify Patients with Significant Intraabdominal Hemorrhage in Life Threatening Pelvic Fractures. AB - BACKGROUND: The Focused Abdominal Sonography for Trauma (FAST) exam has been reported to be unreliable in pelvic fracture patients. Additionally, given the advent of new therapeutic interventions, such as Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA), rapid identification of intraabdominal hemorrhage compared to zone III hemorrhage may guide different therapeutic strategies. We hypothesized that FAST is reliable for detecting clinically significant intraabdominal hemorrhage in the face of complex pelvic fractures. METHODS: Our pelvic fracture database of all hemodynamically unstable patients requiring intervention from 1/1/05 to 7/1/15 was reviewed. FAST exam was compared to operative and CT scan findings. Confirmatory evaluation for FAST(-) patients was considered positive if therapeutic intervention was required. RESULTS: During the study period, 81 patients in refractory shock with FAST imaging in our ED underwent pelvic packing. Mean age was 45 +/- 2 years and ISS was 50 +/- 1.5. The FAST exam was negative in 53 patients; 52 patients did not require operative intervention for abdominal bleeding while 1 patient required splenectomy. FAST exam was positive in 28 patients; 26 had findings confirmed by CT or laparotomy while 2 patients did not have intraabdominal hemorrhage on further evaluation. The sensitivity and specificity for FAST in this population was 96% and 96%; PPV was 93% and NPV was 98%. The false negative and positive rates for FAST were 2% and 7%. CONCLUSIONS: FAST reliably identifies clinically significant hemoperitoneum in life-threatening, pelvic fracture related hemorrhage. The incidence of a false negative FAST in this unstable pelvic fracture population was 2%. FAST results may be used when determining the role of REBOA in these multisystem trauma patients and requires further study. REBOA placement should be considered in hemodynamically unstable pelvic fracture patients who are FAST(-), while laparotomy should be used in FAST(+) patients.

PMID- 29443858 TI - Measurement of compensatory reserve predicts racial differences in tolerance to simulated hemorrhage in women. AB - BACKGROUND: The compensatory reserve measurement (CRM) has been established to accurately measure the body's total integrated capacity to compensate for physiologic states of reduced central blood volume and predict hemodynamic decompensation associated with inadequate tissue oxygenation. We previously demonstrated that African American (AA) women have a higher tolerance to reductions in central blood volume. Therefore, we tested the hypothesis that the CRM would identify racial differences during simulated hemorrhage, before the onset of traditional signs/symptoms. METHODS: We performed a retrospective analysis during simulated hemorrhage using lower-body negative pressure (LBNP) in 23 AA (22 +/- 1 years; 24 +/- 1 kg/m) and 31 white women (WW) (20 +/- 1 years; 23 +/- 1 kg/m). Beat-by-beat blood pressure (BP) and heart rate (HR) were recorded during progressive lower body negative pressure to presyncope. The BP waveforms were analyzed using a machine-learning algorithm to derive the CRM at each lower body negative pressure stage. RESULTS: Resting mean arterial BP (AA, 78 +/- 3 mm Hg vs. WW, 74 +/- 2 mm Hg) and HR (AA, 68 +/- 2 bpm vs. WW, 65 +/- 2 bpm) were similar between groups. The CRM progressively decreased during LBNP in both groups; however, the rate of decline in the CRM was less (p < 0.05) in AA. The CRM was 4% higher in AA at -15 mm Hg LBNP and progressively increased to 21% higher at -50 mm Hg LBNP (p < 0.05). However, changes in BP and HR were not different between groups. CONCLUSION: These data support the notion that the greater tolerance to simulated hemorrhage induced by LBNP in AA women can be explained by their greater capacity to protect the reserve to compensate for progressive central hypovolemia compared with WW, independent of standard vital signs.

AB - BACKGROUND: Elevated International Normalized Ratio (INR) is a marker of poor outcome but not necessarily bleeding or clinical coagulopathy in injured children. Conversely, children with traumatic brain injury (TBI) tend to be hypercoagulable based on rapid thromboelastography (rTEG) parameters. Many clinicians continue to utilize INR as a treatment target. METHODS: Prospective observational study of severely injured children age < 18 with rTEG on arrival and daily thereafter for up to 7 days. Standard rTEG definitions of hyperfibrinolysis (LY30 >= 3), fibrinolysis shutdown (SD) (LY30 <= 0.8), and normal (LY30 = 0.9-2.9) were applied. The first 24-hour blood product transfusion volumes were documented. Abbreviated Injury Scale score >= 3 defined severe TBI. Sustained SD was defined as two consecutive rTEG with SD and no subsequent normalization. Primary outcomes were death and functional disability, based on functional independence measure score assessed at discharge. RESULTS: One hundred one patients were included: median age, 8 years (interquartile range, 4-12 years); Injury Severity Score, 25 (16-30); 72% blunt mechanism; 47% severe TBI; 16% mortality; 45% discharge disability. Neither total volume nor any single product volume transfused (mL/kg; all p > 0.1) differed between TBI and non-TBI groups. On univariate analysis, transfusion of packed red blood cells (p = 0.016), plasma (p < 0.001), and platelets (p = 0.006) were associated with sustained SD; however, in a regression model that included all products (mL/kg) and controlled for severe TBI (head Abbreviated Injury Scale score >= 3), admission INR, polytrauma, and clinical bleeding, only plasma remained an independent predictor of sustained SD (odds ratio, 1.17; p = 0.031). Patients with both severe TBI and plasma transfusion had 100% sustained SD, 75% mortality, and 100% disability in survivors. Admission INR was elevated in TBI patients, but did not correlate with rTEG activated clotting time (p = NS) and was associated with sustained SD (p = 0.006). CONCLUSION: Plasma transfusion is independently associated with sustained fibrinolysis SD. Severe TBI is also associated with sustained SD; the combined effect of plasma transfusion and severe TBI is associated with extremely poor prognosis. Plasma transfusion should not be targeted to INR thresholds but rather to rTEG activated clotting time and clinical bleeding. LEVEL OF EVIDENCE: Prognostic and epidemiological study, level III. PMID- 29443860 TI - A novel rat model of extremity trauma for prehospital pain management research. AB - BACKGROUND: Pain management is important in prehospital care of patients with extremity trauma (ET). The goal of this study was to establish a rat model of ET for prehospital pain research and validate it using pain behaviors and analgesics. METHODS: Rats were anesthetized using isoflurane, and ET was induced in one hindlimb via clamping retrofemoral tissues for 30 seconds, followed by closed fibula fracture. Rats regained consciousness after ET. Pain responses in the injured hindlimb to thermal hyperalgesia (paw withdrawal latency [PWL]), mechanical allodynia (paw withdrawal pressure [PWP]), and weight bearing (WB) were determined before and 90 minutes after ET. Morphine (2 mg/kg), fentanyl (10 MUg/kg), sufentanil (1 MUg/kg), ketamine (5 mg/kg), or vehicle (saline) were then administered via intravenous (i.v.) injection, followed by PWL, PWP, and WB assessments at 10 minutes, 40 minutes, 80 minutes, and 120 minutes after analgesia. RESULTS: After ET, PWL, PWP, and WB were significantly decreased by 61 +/- 4%, 64 +/- 8%, and 65 +/- 4%, respectively, compared with pre-ET values. These pain behaviors were maintained for 3 hours to 4 hours. Compared with the saline group, opioid analgesics significantly increased PWL for at least 80 minutes, with sufentanil exhibiting the highest analgesic effect. An increase in PWL was only observed at 10 minutes after ketamine. The PWP was transiently increased with opioid analgesics for 10 minutes to 40 minutes, but was not changed with ketamine. Weight bearing was improved with opioid analgesics for at least 2 hours, but only for up to 80 minutes with ketamine. CONCLUSION: Our ET model includes long bone fracture and soft tissue injury, but no fixation surgery, mimicking prehospital ET. Our model produces acute, steady, and reproducible trauma-related pain behaviors, and is clinically relevant regarding the pain behaviors and established responses to common analgesics. This model of acute pain due to ET is ideal for prehospital pain management research.

AB - BACKGROUND: The U.S. Navy's casualty-receiving ships provide remote damage control resuscitation platforms to treat injured combatants deployed afloat and ashore. We report a significant mass casualty incident aboard the USS Bataan, and the most warm fresh whole blood (WFWB) transfused at sea for traumatic hemorrhagic shock since the Vietnam War. METHODS: Casualty-receiving ships have robust medical capabilities, including a frozen blood bank with packed red blood cells (pRBC) and fresh frozen plasma (FFP). The blood supply can be augmented with WFWB collected from a "walking blood bank." RESULTS: Following a helicopter crash, six patients were transported by MV-22 Osprey to the USS Bataan. Patient 1 had a pelvic fracture, was managed with a pelvic binder, and received 4 units of pRBC, 2 units of FFP, and 6 units of WFWB. Patient 2, with a comminuted tibia and fibula fracture, underwent lower extremity four-compartment fasciotomy, and received 4 units of WFWB. Patient 3 underwent several procedures, including left anterior thoracotomy, aortic cross-clamping, exploratory laparotomy, small bowel resection, and tracheostomy. He received 8 units of pRBC, 8 units of FFP, and 28 units of WFWB. Patients 4 and 5 had suspected spine injuries and were managed nonoperatively. Patient 6, with open tibia and fibula fractures, underwent lower extremity four-compartment fasciotomy with tibia external fixation and received 1 unit of WFWB. All patients survived aeromedical evacuation to a role 4 medical facility and subsequent transfer to local hospitals. CONCLUSION: Maritime military mass casualty incidents are challenging, but the U.S. Navy's casualty receiving ships are ready to perform remote damage control resuscitation at sea. Activation of the ship's walking blood bank to transfuse WFWB is essential for hemostatic resuscitations afloat. LEVEL OF EVIDENCE: Study type: case series, level V. PMID- 29443863 TI - Trauma-induced insurance instability: Variation in insurance coverage for patients who experience readmission after injury. AB - BACKGROUND: Traumatic injuries result in a significant disruption to patients' lives, including their ability to work, which may place patients at risk of losing insurance coverage. Our objective was to evaluate the impact of injury on insurance status. We hypothesized that trauma patients with ongoing health needs experience changes in coverage. METHODS: We used the Nationwide Readmission Database (2013-2014), a nationally representative sample of readmissions in the United States. We included patients aged 27 years to 64 years admitted with any diagnosis of trauma with at least one readmission within 6 months. Patients on Medicare and with missing payer information were excluded. The primary outcome was payer status. RESULTS: 57,281 patients met inclusion criteria, 11,006 (19%) changed insurance payer at readmission. Of these, 21% (n = 2,288) became uninsured, 25% (n = 2,773) gained coverage, and 54% (n = 5,945) switched insurance. Medicaid and Medicare gained the largest fraction of patients (from 16% to 30% and 0% to 18%, respectively), with a decrease in private payer coverage (37% to 17%). In multivariate analysis, patients who were younger (27-35 years vs. 56-64 years; odds ratio [OR], 1.30; p < 0.001); lived in a zip code with average income in the lowest quartile (vs. the highest quartile; OR, 1.37; p < 0.001); and had three or more comorbidities (vs. none; OR, 1.61; p < 0.001) were more likely to experience a change in insurance. CONCLUSION: Approximately one fifth of trauma patients who are readmitted within 6 months of their injury experience a change in insurance coverage. Most switch between insurers, but nearly a quarter lose their insurance. The government adopts a large fraction of these patients, indicating a growing reliance on government programs like Medicaid. Trauma patients face challenges after injury, and a change in insurance may add to this burden. Future policy and quality improvement initiatives should consider addressing this challenge.

PMID- 29443866 TI - Factors associated with trauma patients' length of stay at Role 2 facilities in Afghanistan, October 2009 to September 2014. AB - BACKGROUND: Understanding patients' length of stay at far-forward Role 2 surgical units may help to determine support needs, stabilization requirements, predeployment training, and necessity of increased care capability before or during transport to a higher level of care. The objectives of this study were to (1) evaluate the amount of time patients spent at Role 2 and (2) determine the factors associated with trauma patients' length of stay at Role 2. METHODS: We conducted a secondary data analysis of the Joint Trauma System Role 2 Database. Logistic regression was used to determine factors associated with extended length of stay at Role 2. RESULTS: There were 7,912 study patients, and the overall median (interquartile range) amount of time patients spent at Role 2 was 2.5 (1.2 5.5) hours. The adjusted odds ratio (aOR) of extended stay for civilian/other forces and non-US military patients were 1.2 (95% confidence interval [CI], 1.0 1.4) and 1.4 (95% CI, 1.2-1.7) times higher as compared with US military patients, respectively. The aOR of extended stay were higher for patients who received blood transfusions (aOR, 1.4; 95% CI, 1.2-1.6), surgical procedures (aOR, 1.6; 95% CI, 1.4-1.8), or did not use a tourniquet (aOR, 1.2; 95% CI, 1.0 1.5). As compared with those injured by an explosion, the adjusted odds of extended stay were 1.2 (95% CI, 1.0-1.4) times higher for patients injured by another mechanism. The odds of extended stay were lower (aOR, 0.3; 95% CI, 0.2 0.5) for patients who died and higher (aOR, 1.4; 95% CI, 1.2-1.6) for transferred patients as compared with patients who returned to duty. CONCLUSION: In this study, interventions, patient affiliation, discharge status, and injury mechanism were associated with length of stay at Role 2. Our study results will help inform training and current Role 2 logistic and personnel support needs. LEVEL OF EVIDENCE: Prognostic, level III. PMID- 29443867 TI - Effects of Whole-Body Vibration Versus Pilates Exercise on Bone Mineral Density in Postmenopausal Women: A Randomized and Controlled Clinical Trial. AB - BACKGROUND AND PURPOSE: Decreased bone mineral density (BMD) is a common condition in postmenopausal women that can be managed with impact activities. Among the activities studied are the whole-body vibration (WBV) and muscle strengthening exercises. The purpose of this study was to compare the effects of WBV versus Pilates exercise on BMD in postmenopausal women. METHODS: In this study, 51 postmenopausal women were randomized into 3 groups: vibration (n = 17), Pilates (n = 17), and control (n = 17). Outcomes were the areal bone mineral density (aBMD) (lumbar spine, femoral neck, total hip, trochanter, intertrochanter, and ward's area) assessed by dual-energy x-ray absorptiometry at baseline and follow-up. The interventions were performed 3 times a week for 6 months, totaling 78 sessions. The analysis was performed with intention-to-treat and covariance analyses adjusted for baseline outcomes. RESULTS: After 6 months, 96.1% of the participants completed the follow-up. The analyses demonstrated significant mean between-group differences in favor of the interventions: vibration versus control, for the aBMD of the lumbar spine (0.014 g/cm; 95% confidence interval [CI], 0.006-0.022; P= .018, d = 1.21) and trochanter (0.018 g/cm; 95% CI, 0.006-0.030; P = .012, d = 1.03); and Pilates versus control, for the aBMD of the lumbar spine (0.016 g/cm; 95% CI, 0.007-0.025; P = .008, d = 1.15) and trochanter (0.020 g/cm; 95% CI, 0.010-0.031; P = .005, d = 1.28). CONCLUSION: In postmenopausal women, 3 weekly sessions of WBV or Pilates administered for 6 months provided an equal effect on BMD. PMID- 29443868 TI - Circular Array of Magnetic Sensors for Current Measurement: Analysis for Error Caused by Position of Conductor. AB - This paper analyzes the measurement error, caused by the position of the current carrying conductor, of a circular array of magnetic sensors for current measurement. The circular array of magnetic sensors is an effective approach for AC or DC non-contact measurement, as it is low-cost, light-weight, has a large linear range, wide bandwidth, and low noise. Especially, it has been claimed that such structure has excellent reduction ability for errors caused by the position of the current-carrying conductor, crosstalk current interference, shape of the conduction cross-section, and the Earth's magnetic field. However, the positions of the current-carrying conductor-including un-centeredness and un perpendicularity-have not been analyzed in detail until now. In this paper, for the purpose of having minimum measurement error, a theoretical analysis has been proposed based on vector inner and exterior product. In the presented mathematical model of relative error, the un-center offset distance, the un perpendicular angle, the radius of the circle, and the number of magnetic sensors are expressed in one equation. The comparison of the relative error caused by the position of the current-carrying conductor between four and eight sensors is conducted. Tunnel magnetoresistance (TMR) sensors are used in the experimental prototype to verify the mathematical model. The analysis results can be the reference to design the details of the circular array of magnetic sensors for current measurement in practical situations. PMID- 29443869 TI - Comparison of Toxic Metal Distribution Characteristics and Health Risk between Cultured and Wild Fish Captured from Honghu City, China. AB - Honghu Lake, which listed in the "Ramsar Convention", is the seventh largest freshwater lake in China and is regarded as one of the biggest freshwater product output areas in China. The toxic element distribution in cultured and wild fish and the corresponding health risks through fish consumption from Honghu area were investigated. The mean concentration in the muscle of cultured and wild fish (Carassius auratus and Ctenopharyngodon idellus) decreased in the order: Zn (18.94) > Cu (0.8489) > Cr (0.2840) > Pb (0.2052) and Zn (16.30) > Cr (1.947) > Cu (0.4166) > Pb (0.0525) > Cd (0.0060) (mean; mg/kg, wet weight). Scales (Multi factor pollution index (MPI) = 3.342) and the liver (MPI = 1.276) were regarded as the main accumulation tissues for cultured fish, and the bladder (MPI = 0.640) and intestine (MPI = 0.477) were regarded as the main accumulation tissues for wild fish. There were no obvious health risks associated with the consumption of cultured and wild fish based on the calculated results of the target hazard quotient (THQ), carcinogenic risk (CR), and estimated weekly intake (EWI). Pb and Cr were recognized as the major health risk contributors for inhabitants through wild and cultured fish consumption. Cultured fish had a greater health risk than wild fish based on the calculation results of THQ and CR. Muscle consumption resulted in more health risks than mixed edible tissues for cultured fish, but for wild fish, the conclusion was the opposite. Mixed fish (cultured:wild = 1:1) muscle consumption had relatively lower risks than the consumption of cultured or wild fish muscle separately. Consuming no more than 465 g/day (wet wt) of cultured fish muscle, 68 g/day (wet wt) of wild fish muscle, 452 g/day (wet wt) of mixed cultured fish edible tissues or 186 g/day (wet wt) of mixed wild fish edible tissues from the Honghu area can assure human health.

AB - Resistance to pyrethroids in mosquitoes is mainly caused by target site insensitivity known as knockdown resistance (kdr). In this work, we examined the point mutations present in portions of domains I, II, III, and IV of the sodium channel gene in Aedes aegypti mosquitoes from three Colombian municipalities. A partial region coding for the sodium channel gene from resistant mosquitoes was sequenced, and a simple allele-specific PCR-based assay (AS-PCR) was used to analyze mutations at the population level. The previously reported mutations, V1016I and F1534C, were found with frequencies ranging from 0.04 to 0.41, and 0.56 to 0.71, respectively, in the three cities. Moreover, a novel mutation, at 419 codon (V419L), was found in Ae. aegypti populations from Bello, Riohacha and Villavicencio cities with allelic frequencies of 0.06, 0.36, and 0.46, respectively. Interestingly, the insecticide susceptibility assays showed that mosquitoes from Bello were susceptible to lambda-cyhalothrin pyrethroid whilst those from Riohacha and Villavicencio were resistant. A positive association between V419L and V1016I mutations with lambda-cyhalothrin resistance was established in Riohacha and Villavicencio. The frequency of the F1534C was high in the three populations, suggesting that this mutation could be conferring resistance to insecticides other than lambda-cyhalothrin, particularly type I pyrethroids. Further studies are required to confirm this hypothesis.

AB - Coalbed methane (CBM) is one kind of clean-burning gas and has been valued as a new form of energy that will be used widely in the near future. When producing CBM, the working level within a CBM wellbore annulus needs to be monitored to dynamically adjust the gas drainage and extraction processes. However, the existing method of measuring the working level does not meet the needs of accurate adjustment, so we designed a new sensor for this purpose. The principle of our sensor is a liquid pressure formula, i.e., the sensor monitors the two phase flow patterns and obtains the mean density of the two-phase flow according to the pattern recognition result in the first step, and then combines the pressure data of the working level to calculate the working level using the liquid pressure formula. The sensor was tested in both the lab and on site, and the tests showed that the sensor's error was +/-8% and that the sensor could function well in practical conditions and remain stable in the long term. PMID- 29443872 TI - AP-1/KIF13A Blocking Peptides Impair Melanosome Maturation and Melanin Synthesis. AB - Melanocytes are specialized cells that generate unique organelles called melanosomes in which melanin is synthesized and stored. Melanosome biogenesis and melanocyte pigmentation require the transport and delivery of melanin synthesizing enzymes, such as tyrosinase and related proteins (e.g., TYRP1), from endosomes to maturing melanosomes. Among the proteins controlling endosome melanosome transport, AP-1 together with KIF13A coordinates the endosomal sorting and trafficking of TYRP1 to melanosomes. We identify here beta1-adaptin AP-1 subunit-derived peptides of 5 amino acids that block the interaction of KIF13A with AP-1 in cells. Incubating these peptides with human MNT-1 cells or 3D reconstructed pigmented epidermis decreases pigmentation by impacting the maturation of melanosomes in fully pigmented organelles. This study highlights that peptides targeting the intracellular trafficking of melanocytes are candidate molecules to tune pigmentation in health and disease. PMID- 29443873 TI - A Ketogenic Formula Prevents Tumor Progression and Cancer Cachexia by Attenuating Systemic Inflammation in Colon 26 Tumor-Bearing Mice. AB - Low-carbohydrate, high-fat diets (ketogenic diets) might prevent tumor progression and could be used as supportive therapy; however, few studies have addressed the effect of such diets on colorectal cancer. An infant formula with a ketogenic composition (ketogenic formula; KF) is used to treat patients with refractory epilepsy. We investigated the effect of KF on cancer and cancer cachexia in colon tumor-bearing mice. Mice were randomized into normal (NR), tumor-bearing (TB), and ketogenic formula (KF) groups. Colon 26 cells were inoculated subcutaneously into TB and KF mice. The NR and TB groups received a standard diet, and the KF mice received KF ad libitum. KF mice preserved their body, muscle, and carcass weights. Tumor weight and plasma IL-6 levels were significantly lower in KF mice than in TB mice. In the KF group, energy intake was significantly higher than that in the other two groups. Blood ketone body concentrations in KF mice were significantly elevated, and there was a significant negative correlation between blood ketone body concentration and tumor weight. Therefore, KF may suppress the progression of cancer and the accompanying systemic inflammation without adverse effects on weight gain, or muscle mass, which might help to prevent cancer cachexia. PMID- 29443874 TI - Dental Application of Natural Products. AB - This review article summarizes the recent progress in dental applications of natural products. Catechin gel showed selective antimicrobial activity, whereas the alkaline extract of various plant species rich in lignin carbohydrate complex (LCC) showed much higher antiviral activity than lower molecular weight polyphenols. Mouthwash with the alkaline extract of a plant classified as OTC effectively reduced halitosis. Unexpectedly, many polyphenolic compounds purified from the natural kingdom showed much lower tumor-specificity against human oral squamous cell lines as compared with antitumor agents, although they showed apoptosis-inducing activity. The alkaline extract of bamboo leaf, which exerted various common biological activities with LCC, showed osteogenic activity by stimulating differentiation toward osteoblasts while inhibiting differentiation toward osteoclasts. LCC enhanced the dectin-2 mRNA expression in macrophages, whereas glucan showed anti-osteoblastic action via dectin-1. These data suggest that natural products exert their biological activity by interacting with these molecules. PMID- 29443875 TI - On the Reaction Mechanism of the 3,4-Dimethoxybenzaldehyde Formation from 1 (3',4'-Dimethoxyphenyl)Propene. AB - Lignin peroxidase (LiP) is an important enzyme for degrading aromatic hydrocarbons not only in nature but also in industry. In the presence of H2O2, this enzyme can easily decompose lignin and analogue compounds under mild conditions. In this reaction mechanism, LiP catalyzes the C-C cleavage of a propenyl side chain, being able to produce veratraldehyde (VAD) from 1-(3',4' dimethoxyphenyl) propene (DMPP). One of the few and complete proposed mechanisms includes several non-enzymatic reactions. In this study, we performed a computational study to gain insight about the non-enzymatic steps involved in the reaction mechanism of VAD formation from DMPP using LiP as a catalyst. A kinetic characterization of the reaction using the reaction force and the reaction force constant concepts within the density functional theory (DFT) framework is proposed. All theoretical calculations for the reaction pathway were performed using the Minnesota Global Hybrid functional M06-2X and a 6-31++G(d,p) basis set. The complete reaction comprises seven steps (five steps not including LiP as a catalyst), which include radical species formation, bond transformation, water and oxygen addition, atom reordering, and deacetylation. The overall mechanism is an endothermic process with mixed activation energies depending on the four transition states. These results are the first attempt to fully understand the catalytic role of LiP in the degradation of lignin and its aromatic derivative compounds in terms of the electronic structure methods and future hybrid calculation approaches that we have recently been performing. PMID- 29443876 TI - Analysing the Zenith Tropospheric Delay Estimates in On-line Precise Point Positioning (PPP) Services and PPP Software Packages. AB - As Global Navigation Satellite System (GNSS) signals travel through the troposphere, a tropospheric delay occurs due to a change in the refractive index of the medium. The Precise Point Positioning (PPP) technique can achieve centimeter/millimeter positioning accuracy with only one GNSS receiver. The Zenith Tropospheric Delay (ZTD) is estimated alongside with the position unknowns in PPP. Estimated ZTD can be very useful for meteorological applications, an example is the estimation of water vapor content in the atmosphere from the estimated ZTD. PPP is implemented with different algorithms and models in online services and software packages. In this study, a performance assessment with analysis of ZTD estimates from three PPP online services and three software packages is presented. The main contribution of this paper is to show the accuracy of ZTD estimation achievable in PPP. The analysis also provides the GNSS users and researchers the insight of the processing algorithm dependence and impact on PPP ZTD estimation. Observation data of eight whole days from a total of nine International GNSS Service (IGS) tracking stations spread in the northern hemisphere, the equatorial region and the southern hemisphere is used in this analysis. The PPP ZTD estimates are compared with the ZTD obtained from the IGS tropospheric product of the same days. The estimates of two of the three online PPP services show good agreement (<1 cm) with the IGS ZTD values at the northern and southern hemisphere stations. The results also show that the online PPP services perform better than the selected PPP software packages at all stations.

AB - Background: High incidences of drug consumption and mental health problems are found among the Roma population in Spain, a reality that remains understudied. Past studies have indicated the positive role played by the Iglesia Evangelica Filadelfia (IEF) in promoting rehabilitation and prevention of these practices. Objective: In this article, authors analyze in which ways the IEF favors processes of drug rehabilitation and mental health recovery as well as the prevention of these problems among its Roma members. Methods: A communicative qualitative approach was developed. It was communicative because new knowledge was created by dialogically contrasting the existing state of the art with study participants. It was qualitative because everyday life stories were collected, gathering the experiences, perceptions and interpretations of Roma people who are actively involved in three different IEF churches based in Barcelona. Results: This article identifies these protective factors: anti-drug discourse, a supportive environment, new social relations, role model status, the promotion of interactions, the revaluation of oneself, spiritual activities and the improvement of the feeling of belonging and the creation of meaning. Conclusion: The present research contributes new evidence to the current understanding of the role played by the IEF in improving Roma health status and how the identified protective factors can contribute to rehabilitation and recovery from such problems in other contexts. PMID- 29443878 TI - Skeletal Muscle Pathophysiology: The Emerging Role of Spermine Oxidase and Spermidine. AB - Skeletal muscle comprises approximately 40% of the total body mass. Preserving muscle health and function is essential for the entire body in order to counteract chronic diseases such as type II diabetes, cardiovascular diseases, and cancer. Prolonged physical inactivity, particularly among the elderly, causes muscle atrophy, a pathological state with adverse outcomes such as poor quality of life, physical disability, and high mortality. In murine skeletal muscle C2C12 cells, increased expression of the spermine oxidase (SMOX) enzyme has been found during cell differentiation. Notably, SMOX overexpression increases muscle fiber size, while SMOX reduction was enough to induce muscle atrophy in multiple murine models. Of note, the SMOX reaction product spermidine appears to be involved in skeletal muscle atrophy/hypertrophy. It is effective in reactivating autophagy, ameliorating the myopathic defects of collagen VI-null mice. Moreover, spermidine treatment, if combined with exercise, can affect D-gal-induced aging-related skeletal muscle atrophy. This review hypothesizes a role for SMOX during skeletal muscle differentiation and outlines its role and that of spermidine in muscle atrophy. The identification of new molecular pathways involved in the maintenance of skeletal muscle health could be beneficial in developing novel therapeutic lead compounds to treat muscle atrophy. PMID- 29443880 TI - Magnetic Nanoparticles Interact and Pass an In Vitro Co-Culture Blood-Placenta Barrier Model. AB - Magnetic nanoparticles are interesting tools for biomedicine. Before application, critical prerequisites have to be fulfilled. An important issue is the contact and interaction with biological barriers such as the blood-placenta barrier. In order to study these processes in detail, suitable in vitro models are needed. For that purpose a blood-placenta barrier model based on the trophoblast-like cell line BeWo and primary placenta-derived pericytes was established. This model was characterized by molecular permeability, transepithelial electrical resistance and cell-cell-contact markers. Superparamagnetic iron oxide nanoparticles (SPIONs) with cationic, anionic or neutral surface charge were applied. The localization of the nanoparticles within the cells was illustrated by histochemistry. The time-dependent passage of the nanoparticles through the BeWo/pericyte barrier was measured by magnetic particle spectroscopy and atomic absorption spectroscopy. Cationically coated SPIONs exhibited the most extensive interaction with the BeWo cells and remained primarily in the BeWo/pericyte cell layer. In contrast, SPIONs with neutral and anionic surface charge were able to pass the cell layer to a higher extent and could be detected beyond the barrier after 24 h. This study showed that the mode of SPION interaction with and passage through the in vitro blood-placenta barrier model depends on the surface charge and the duration of treatment. PMID- 29443879 TI - Comparison of Rumen and Manure Microbiomes and Implications for the Inoculation of Anaerobic Digesters. AB - Cattle manure is frequently used as an inoculum for the start-up of agricultural biogas plants or as a co-substrate in the anaerobic digestion of lignocellulosic feedstock. Ruminal microbiota are considered to be effective plant fiber degraders, but the microbes contained in manure do not necessarily reflect the rumen microbiome. The aim of this study was to compare the microbial community composition of cow rumen and manure with respect to plant fiber-digesting microbes. Bacterial and methanogenic communities of rumen and manure samples were examined by 454 amplicon sequencing of bacterial 16S rRNA genes and mcrA genes, respectively. Rumen fluid samples were dominated by Prevotellaceae (29%), whereas Ruminococcaceae was the most abundant family in the manure samples (31%). Fibrobacteraceae (12%) and Bacteroidaceae (13%) were the second most abundant families in rumen fluid and manure, respectively. The high abundances of fiber degrading bacteria belonging to Prevotellaceae and Fibrobacteraceae might explain the better performance of anaerobic digesters inoculated with rumen fluid. Members of the genus Methanobrevibacter were the predominant methanogens in the rumen fluid, whereas methanogenic communities of the manure samples were dominated by the candidate genus Methanoplasma. Our results suggest that inoculation or bioaugmentation with fiber-digesting rumen microbiota can enhance the anaerobic digestion of lignocellulosic biomass. PMID- 29443881 TI - GWAS Uncovers Differential Genetic Bases for Drought and Salt Tolerances in Sesame at the Germination Stage. AB - Sesame has great potential as an industrial crop but its production is challenged by drought and salt stresses. To unravel the genetic variants leading to salinity and drought tolerances at the germination stage, genome-wide association studies of stress tolerance indexes related to NaCl-salt and polyethylene glycol-drought induced stresses were performed with a diversity panel of 490 sesame accessions. An extensive variation was observed for drought and salt responses in the population and most of the accessions were moderately tolerant to both stresses. A total of 132 and 120 significant Single Nucleotide Polymorphisms (SNPs) resolved to nine and 15 Quantitative trait loci (QTLs) were detected for drought and salt stresses, respectively. Only two common QTLs for drought and salt responses were found located on linkage groups 5 and 7, respectively. This indicates that the genetic bases for drought and salt responses in sesame are different. A total of 13 and 27 potential candidate genes were uncovered for drought and salt tolerance indexes, respectively, encoding transcription factors, antioxidative enzymes, osmoprotectants and involved in hormonal biosynthesis, signal transduction or ion sequestration. The identified SNPs and potential candidate genes represent valuable resources for future functional characterization towards the enhancement of sesame cultivars for drought and salt tolerances. PMID- 29443882 TI - Effects of TROL Presequence Mutagenesis on Its Import and Dual Localization in Chloroplasts. AB - Thylakoid rhodanase-like protein (TROL) is involved in the final step of photosynthetic electron transport from ferredoxin to ferredoxin: NADP+ oxidoreductase (FNR). TROL is located in two distinct chloroplast compartments-in the inner envelope of chloroplasts, in its precursor form; and in the thylakoid membranes, in its fully processed form. Its role in the inner envelope, as well as the determinants for its differential localization, have not been resolved yet. In this work we created six N-terminal amino acid substitutions surrounding the predicted processing site in the presequence of TROL in order to obtain a construct whose import is affected or localization limited to a single intrachloroplastic site. By using in vitro transcription and translation and subsequent protein import methods, we found that a single amino acid exchange in the presequence, Ala67 to Ile67 interferes with processing in the stroma and directs the whole pool of in vitro translated TROL to the inner envelope of chloroplasts. This result opens up the possibility of studying the role of TROL in the chloroplast inner envelope as well as possible consequence/s of its absence from the thylakoids. PMID- 29443883 TI - Synthesis, Characterization, and Computational Modeling of N-(1 Ethoxyvinyl)pyridinium Triflates, an Unusual Class of Pyridinium Salts. AB - N-Substituted pyridinium salts constitute one of the most valuable reagent classes in organic synthesis, due to their versatility and ease of use. Herein we report a preliminary synthesis and detailed structural analysis of several N-(1 ethoxyvinyl)pyridinium triflates, an unusual class of pyridinium salts with potentially broad use as a reagent in organic synthesis. Treatment of pyridines with trifluoromethane sulfonic acid and ethoxyacetylene generates stable, isolable adducts which have been extensively characterized, due to their novelty. Three-dimensional structural stability is perpetuated by an array of C-H***O hydrogen bonds involving oxygen atoms from the -SO3 groups of the triflate anion, and hydrogen atoms from the aromatic ring and vinyl group of the pyridinium cation. Predictions from density functional theory calculations of the energy landscape for rotation about the exocyclic C-N bond of 2-chloro-1-(1 ethoxyvinyl)pyridine-1-ium trifluoromethanesulfonate (7) and 1-(1 ethoxyvinyl)pyridine-1-ium trifluoromethanesulfonate (16) are also reported. Notably, the predicted global energy minimum of 7 was nearly identical to that found within the crystal structure. PMID- 29443884 TI - Linear Regression QSAR Models for Polo-Like Kinase-1 Inhibitors. AB - A structurally diverse dataset of 530 polo-like kinase-1 (PLK1) inhibitors is compiled from the ChEMBL database and studied by means of a conformation independent quantitative structure-activity relationship (QSAR) approach. A large number (26,761) of molecular descriptors are explored with the main intention of capturing the most relevant structural characteristics affecting the bioactivity. The structural descriptors are derived with different freeware, such as PaDEL, Mold2, and QuBiLs-MAS; such descriptor software complements each other and improves the QSAR results. The best multivariable linear regression models are found with the replacement method variable subset selection technique. The balanced subsets method partitions the dataset into training, validation, and test sets. It is found that the proposed linear QSAR model improves previously reported models by leading to a simpler alternative structure-activity relationship. PMID- 29443885 TI - Genome Size Diversity and Its Impact on the Evolution of Land Plants. AB - Genome size is a biodiversity trait that shows staggering diversity across eukaryotes, varying over 64,000-fold. Of all major taxonomic groups, land plants stand out due to their staggering genome size diversity, ranging ca. 2400-fold. As our understanding of the implications and significance of this remarkable genome size diversity in land plants grows, it is becoming increasingly evident that this trait plays not only an important role in shaping the evolution of plant genomes, but also in influencing plant community assemblages at the ecosystem level. Recent advances and improvements in novel sequencing technologies, as well as analytical tools, make it possible to gain critical insights into the genomic and epigenetic mechanisms underpinning genome size changes. In this review we provide an overview of our current understanding of genome size diversity across the different land plant groups, its implications on the biology of the genome and what future directions need to be addressed to fill key knowledge gaps. PMID- 29443886 TI - Antibacterial Peptides in Dermatology-Strategies for Evaluation of Allergic Potential. AB - During recent decades, the market for peptide-based drugs, including antimicrobial peptides, has vastly extended and evolved. These drugs can be useful in treatment of various types of disorders, e.g., cancer, autoimmune diseases, infections, and non-healing wounds. Although peptides are less immunogenic than other biologic therapeutics, they can still induce immune responses and cause allergies. It is important to evaluate the immunogenic and allergic potential of peptides before they are forwarded to the expensive stages of clinical trials. The process of the evaluation of immunogenicity and cytotoxicity is complicated, as in vitro models and bioinformatics tools cannot fully simulate situations in the clinic. Nevertheless, several potentially promising tests for the preclinical evaluation of peptide drugs have been implemented (e.g., cytotoxicity assays, the basophil activation test, and lymphocyte activation assays). In this review, we focus on strategies for evaluation of the allergic potential of peptide-based therapeutics. PMID- 29443887 TI - Impact of Mutations in the Hemagglutinin of H10N7 Viruses Isolated from Seals on Virus Replication in Avian and Human Cells. AB - Wild birds are the reservoir for low-pathogenic avian influenza viruses, which are frequently transmitted to domestic birds and occasionally to mammals. In 2014, an H10N7 virus caused severe mortality in harbor seals in northeastern Europe. Although the hemagglutinin (HA) of this virus was closely related to H10 of avian H10N4 virus, it possessed unique nonsynonymous mutations, particularly in the HA1 subunit in or adjacent to the receptor binding domain and proteolytic cleavage site. Here, the impact of these mutations on virus replication was studied in vitro. Using reverse genetics, an avian H10N4 virus was cloned, and nine recombinant viruses carrying one of eight unique mutations or the complete HA from the seal virus were rescued. Receptor binding affinity, replication in avian and mammalian cell cultures, cell-to-cell spread, and HA cleavability of these recombinant viruses were studied. Results show that wild-type recombinant H10N4 virus has high affinity to avian-type sialic acid receptors and no affinity to mammalian-type receptors. The H10N7 virus exhibits dual receptor binding affinity. Interestingly, Q220L (H10 numbering) in the rim of the receptor binding pocket increased the affinity of the H10N4 virus to mammal-type receptors and completely abolished the affinity to avian-type receptors. No remarkable differences in cell-to-cell spread or HA cleavability were observed. All viruses, including the wild-type H10N7 virus, replicated at higher levels in chicken cells than in human cells. These results indicate that H10N7 acquired adaptive mutations (e.g., Q220L) to enhance replication in mammals and retained replication efficiency in the original avian host. PMID- 29443888 TI - Assessing the Potential for Rooftop Rainwater Harvesting from Large Public Institutions. AB - As in many other cities, urbanization coupled with population growth worsens the water supply problem of Addis Ababa, Ethiopia, with a water supply deficit of 41% in 2016. To investigate the potential contribution of rooftop rainwater harvesting (RWH) from large public institutions, 320 such institutions were selected and grouped into 11 categories, from which 25-30% representative 588 rooftops were digitalized and the potential RWH volume computed based on a ten year rainfall dataset. When comparing the resulting RWH potential with the water consumption, up to 2.3% of the annual, potable water supply can be provided. If reused only within one's own institution, the self-sufficiency varies from 0.9 to 649%. Non-uniform rainfall patterns add uncertainty to these numbers, since the size of the storage tank becomes critical for coverage in the dry season from October to May. Despite the low replacement potential at the city level, RWH from large institutions will enable a significant volume of potable water to be transferred to localities critically suffering from water shortage. Further, large institutions may demonstrate how RWH can be practiced, thus acting as a frontrunner for the dissemination of RWH to other types of rooftops. To narrow the water supply gap, considering rooftop RWH as an alternative water supply source is recommended. However, the present study assumed that financial constraints to install large sized storage tanks are considered as a possible challenge. Thus, future research is needed to investigate the cost-benefit balance along with the invention of a cheap storage tank as they may affect the potential contribution of RWH from rooftops. PMID- 29443890 TI - Embedded Disposable Functionalized Electrochemical Biosensor with a 3D-Printed Flow Cell for Detection of Hepatic Oval Cells (HOCs). AB - Hepatic oval cells (HOCs) are considered the progeny of the intrahepatic stem cells that are found in a small population in the liver after hepatocyte proliferation is inhibited. Due to their small number, isolation and capture of these cells constitute a challenging task for immunosensor technology. This work describes the development of a 3D-printed continuous flow system and exploits disposable screen-printed electrodes for the rapid detection of HOCs that over express the OV6 marker on their membrane. Multiwall carbon nanotube (MWCNT) electrodes have a chitosan film that serves as a scaffold for the immobilization of oval cell marker antibodies (anti-OV6-Ab), which enhance the sensitivity of the biomarker and makes the designed sensor specific for oval cells. The developed sensor can be easily embedded into the 3D-printed flow cell to allow cells to be exposed continuously to the functionalized surface. The continuous flow is intended to increase capture of most of the target cells in the specimen. Contact angle measurements were performed to characterize the nature and quality of the modified sensor surface, and electrochemical measurements (cyclic voltammetry (CV) and square wave voltammetry (SWV)) were performed to confirm the efficiency and selectivity of the fabricated sensor to detect HOCs. The proposed method is valuable for capturing rare cells and could provide an effective tool for cancer diagnosis and detection. PMID- 29443889 TI - Alteration of Epigenetic Regulation by Long Noncoding RNAs in Cancer. AB - Long noncoding RNAs (lncRNAs) are important regulators of the epigenetic status of the human genome. Besides their participation to normal physiology, lncRNA expression and function have been already associated to many diseases, including cancer. By interacting with epigenetic regulators and by controlling chromatin topology, their misregulation may result in an aberrant regulation of gene expression that may contribute to tumorigenesis. Here, we review the functional role and mechanisms of action of lncRNAs implicated in the aberrant epigenetic regulation that has characterized cancer development and progression. PMID- 29443891 TI - Conformational Dynamics and Stability of U-Shaped and S-Shaped Amyloid beta Assemblies. AB - Alzheimer's disease is the most fatal neurodegenerative disorder characterized by the aggregation and deposition of Amyloid beta (Abeta) oligomers in the brain of patients. Two principal variants of Abeta exist in humans: Abeta1-40 and Abeta1 42. The former is the most abundant in the plaques, while the latter is the most toxic species and forms fibrils more rapidly. Interestingly, fibrils of Abeta1-40 peptides can only assume U-shaped conformations while Abeta1-42 can also arrange as S-shaped three-stranded chains, as recently discovered. As alterations in protein conformational arrangement correlate with cell toxicity and speed of disease progression, it is important to characterize, at molecular level, the conformational dynamics of amyloid fibrils. In this work, Replica Exchange Molecular Dynamics simulations were carried out to compare the conformational dynamics of U-shaped and S-shaped Abeta17-42 small fibrils. Our computational results provide support for the stability of the recently proposed S-shaped model due to the maximized interactions involving the C-terminal residues. On the other hand, the U-shaped motif is characterized by significant distortions resulting in a more disordered assembly. Outcomes of our work suggest that the molecular architecture of the protein aggregates might play a pivotal role in formation and conformational stability of the resulting fibrils. PMID- 29443892 TI - An Exploration of Underrepresentation of Aboriginal Cancer Patients Attending a Regional Radiotherapy Service in Western Australia. AB - Travel logistics impede Aboriginal patients' uptake of cancer treatments and is one reason for the poorer outcomes of Aboriginal people with cancer. This research examined benefits of a newly established rurally based radiotherapy unit in southwest Western Australia (WA), and included exploring the experience of Aboriginal patients and possible reasons for Aboriginal people's underrepresentation in treatment. Semi-structured in-depth interviews with 21 service providers involved in the treatment and care of people with cancer, and 3 Aboriginal patients with cancer who undertook radiotherapy at the Service were undertaken. Data were subject to thematic analysis involving immersion in the data for familiarization, inductive coding, investigator discussion and refining of emerging themes and triangulation of patient and provider interviews. Aboriginal cancer patients were positive about the treatment and support they had received, highlighting the often complex challenges faced by rural Aboriginal cancer patients in accessing and maintaining treatment. Service providers offered suggestions for small numbers presenting to the Service, including late presentation, potential perceptions of cultural insensitivity on the part of service providers, out-of-pocket costs and under-ascertainment of Aboriginal status. The Service has put in place practices and initiatives to support patient health and wellbeing, including making the facility more welcoming towards Aboriginal people and ensuring culturally appropriate care. PMID- 29443893 TI - A Modular IoT Platform for Real-Time Indoor Air Quality Monitoring. AB - The impact of air quality on health and on life comfort is well established. In many societies, vulnerable elderly and young populations spend most of their time indoors. Therefore, indoor air quality monitoring (IAQM) is of great importance to human health. Engineers and researchers are increasingly focusing their efforts on the design of real-time IAQM systems using wireless sensor networks. This paper presents an end-to-end IAQM system enabling measurement of CO2, CO, SO2, NO2, O3, Cl2, ambient temperature, and relative humidity. In IAQM systems, remote users usually use a local gateway to connect wireless sensor nodes in a given monitoring site to the external world for ubiquitous access of data. In this work, the role of the gateway in processing collected air quality data and its reliable dissemination to end-users through a web-server is emphasized. A mechanism for the backup and the restoration of the collected data in the case of Internet outage is presented. The system is adapted to an open-source Internet-of Things (IoT) web-server platform, called Emoncms, for live monitoring and long term storage of the collected IAQM data. A modular IAQM architecture is adopted, which results in a smart scalable system that allows seamless integration of various sensing technologies, wireless sensor networks (WSNs) and smart mobile standards. The paper gives full hardware and software details of the proposed solution. Sample IAQM results collected in various locations are also presented to demonstrate the abilities of the system.

AB - Current animal research ethics frameworks emphasise consequentialist ethics through cost-benefit or harm-benefit analysis. However, these ethical frameworks along with institutional animal ethics approval processes cannot satisfactorily decide when a given potential benefit is outweighed by costs to animals. The consequentialist calculus should, theoretically, provide for situations where research into a disease or disorder is no longer ethical, but this is difficult to determine objectively. Public support for animal research is also falling as demand for healthcare is rising. Democratisation of animal research could help resolve these tensions through facilitating ethical health consumerism or giving the public greater input into deciding the diseases and disorders where animal research is justified. Labelling drugs to disclose animal use and providing a plain-language summary of the role of animals may help promote public understanding and would respect the ethical beliefs of objectors to animal research. National animal ethics committees could weigh the competing ethical, scientific, and public interests to provide a transparent mandate for animal research to occur when it is justifiable and acceptable. Democratic processes can impose ethical limits and provide mandates for acceptable research while facilitating a regulatory and scientific transition towards medical advances that require fewer animals. PMID- 29443897 TI - Structured Kernel Subspace Learning for Autonomous Robot Navigation. AB - This paper considers two important problems for autonomous robot navigation in a dynamic environment, where the goal is to predict pedestrian motion and control a robot with the prediction for safe navigation. While there are several methods for predicting the motion of a pedestrian and controlling a robot to avoid incoming pedestrians, it is still difficult to safely navigate in a dynamic environment due to challenges, such as the varying quality and complexity of training data with unwanted noises. This paper addresses these challenges simultaneously by proposing a robust kernel subspace learning algorithm based on the recent advances in nuclear-norm and l 1 -norm minimization. We model the motion of a pedestrian and the robot controller using Gaussian processes. The proposed method efficiently approximates a kernel matrix used in Gaussian process regression by learning low-rank structured matrix (with symmetric positive semi definiteness) to find an orthogonal basis, which eliminates the effects of erroneous and inconsistent data. Based on structured kernel subspace learning, we propose a robust motion model and motion controller for safe navigation in dynamic environments. We evaluate the proposed robust kernel learning in various tasks, including regression, motion prediction, and motion control problems, and demonstrate that the proposed learning-based systems are robust against outliers and outperform existing regression and navigation methods.

AB - Dispersal of Glioblastoma (GBM) renders localized therapy ineffective and is a major cause of recurrence. Previous studies have demonstrated that Dexamethasone (Dex), a drug currently used to treat brain tumor-related edema, can also significantly reduce dispersal of human primary GBM cells from neurospheres. It does so by triggering alpha5 integrin activity, leading to restoration of fibronectin matrix assembly (FNMA), increased neurosphere cohesion, and reduction of neurosphere dispersal velocity (DV). How Dex specifically activates alpha5 integrin in these GBM lines is unknown. Several chaperone proteins are known to activate integrins, including calreticulin (CALR). We explore the role of CALR as a potential mediator of Dex-dependent induction of alpha5 integrin activity in primary human GBM cells. We use CALR knock-down and knock-in strategies to explore the effects on FNMA, aggregate compaction, and dispersal velocity in vitro, as well as dispersal ex vivo on extirpated mouse retina and brain slices. We show that Dex increases CALR expression and that siRNA knockdown suppresses Dex-mediated FNMA. Overexpression of CALR in GBM cells activates FNMA, increases compaction, and decreases DV in vitro and on explants of mouse retina and brain slices. Our results define a novel interaction between Dex, CALR, and FNMA as inhibitors of GBM dispersal.

AB - Nine 2-(1,2-benzothiazol-3-yl)-N-(4-oxo-2-phenyl-1,3-thiazolidin-3 yl)propanamides combining a benzisothiazole and 4-thiazolidinone in one framework were designed and synthesized. The aim of the study was to verify their effectiveness to affect the inflammatory/oxidative process in which free oxygen and nitrite (ROS and RNS) radicals, inflammatory mediators, such as nuclear factor kappaB (NF-kappaB), and matrix metalloproteinases (MMPs) are involved. Docking studies of all the compounds were performed in order to explore their binding mode at the MMP-9 protein. An appreciable anti-inflammatory/potential wound healing effects of the tested compounds was highlighted. Derivative 23, bearing a 4-carboxyphenyl substituent at C2 of the 4-thiazolidinone ring, exhibited the highest activity, being able to inhibit MMP-9 at nanomolar level(IC50 = 40 nM). PMID- 29443900 TI - Multisensor Analysis of Spectral Dimensionality and Soil Diversity in the Great Central Valley of California. AB - Planned hyperspectral satellite missions and the decreased revisit time of multispectral imaging offer the potential for data fusion to leverage both the spectral resolution of hyperspectral sensors and the temporal resolution of multispectral constellations. Hyperspectral imagery can also be used to better understand fundamental properties of multispectral data. In this analysis, we use five flight lines from the Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) archive with coincident Landsat 8 acquisitions over a spectrally diverse region of California to address the following questions: (1) How much of the spectral dimensionality of hyperspectral data is captured in multispectral data?; (2) Is the characteristic pyramidal structure of the multispectral feature space also present in the low order dimensions of the hyperspectral feature space at comparable spatial scales?; (3) How much variability in rock and soil substrate endmembers (EMs) present in hyperspectral data is captured by multispectral sensors? We find nearly identical partitions of variance, low-order feature space topologies, and EM spectra for hyperspectral and multispectral image composites. The resulting feature spaces and EMs are also very similar to those from previous global multispectral analyses, implying that the fundamental structure of the global feature space is present in our relatively small spatial subset of California. Finally, we find that the multispectral dataset well represents the substrate EM variability present in the study area - despite its inability to resolve narrow band absorptions. We observe a tentative but consistent physical relationship between the gradation of substrate reflectance in the feature space and the gradation of sand versus clay content in the soil classification system. PMID- 29443899 TI - Protease-Activated Receptor 4 (PAR4): A Promising Target for Antiplatelet Therapy. AB - Cardiovascular diseases (CVDs) are currently among the leading causes of death worldwide. Platelet aggregation is a key cellular component of arterial thrombi and major cause of CVDs. Protease-activated receptors (PARs), including PAR1, PAR2, PAR3 and PAR4, fall within a subfamily of seven-transmembrane G-protein coupled receptors (GPCR). Human platelets express PAR1 and PAR4, which contribute to the signaling transduction processes. In association with CVDs, PAR4 not only contributes to platelet activation but also is a modulator of cellular responses that serve as hallmarks of inflammation. Although several antiplatelet drugs are available on the market, they have many side effects that limit their use. Emerging evidence shows that PAR4 targeting is a safer strategy for preventing thrombosis and consequently may improve the overall cardiac safety profile. Our present review summarizes the PAR4 structural characteristics, activation mechanism, role in the pathophysiology of diseases and understanding the association of PAR4 targeting for improved cardiac protection. Conclusively, this review highlights the importance of PAR4 antagonists and its potential utility in different CVDs. PMID- 29443903 TI - QLog Solar-Cell Mode Photodiode Logarithmic CMOS Pixel Using Charge Compression and Readout. AB - In this paper, we present a new logarithmic pixel design currently under development at New Imaging Technologies SA (NIT). This new logarithmic pixel design uses charge domain logarithmic signal compression and charge-transfer based signal readout. This structure gives a linear response in low light conditions and logarithmic response in high light conditions. The charge transfer readout efficiently suppresses the reset (KTC) noise by using true correlated double sampling (CDS) in low light conditions. In high light conditions, thanks to charge domain logarithmic compression, it has been demonstrated that 3000 electrons should be enough to cover a 120 dB dynamic range with a mobile phone camera-like signal-to-noise ratio (SNR) over the whole dynamic range. This low electron count permits the use of ultra-small floating diffusion capacitance (sub fF) without charge overflow. The resulting large conversion gain permits a single photon detection capability with a wide dynamic range without a complex sensor/system design. A first prototype sensor with 320 * 240 pixels has been implemented to validate this charge domain logarithmic pixel concept and modeling. The first experimental results validate the logarithmic charge compression theory and the low readout noise due to the charge-transfer-based readout.

AB - Plants have been explored for many years as inexpensive and versatile platforms for the generation of vaccines and other biopharmaceuticals. Plant viruses have also been engineered to either express subunit vaccines or act as epitope presentation systems. Both icosahedral and helical, filamentous-shaped plant viruses have been used for these purposes. More recently, plant viruses have been utilized as nanoparticles to transport drugs and active molecules into cancer cells. The following review describes the use of both icosahedral and helical plant viruses in a variety of new functions against cancer. The review illustrates the breadth of variation among different plant virus nanoparticles and how this impacts the immune response. PMID- 29443901 TI - Toxicology of Engineered Nanoparticles: Focus on Poly(amidoamine) Dendrimers. AB - Engineered nanomaterials are increasingly being developed for paints, sunscreens, cosmetics, industrial lubricants, tyres, semiconductor devices, and also for biomedical applications such as in diagnostics, therapeutics, and contrast agents. As a result, nanomaterials are being manufactured, transported, and used in larger and larger quantities, and potential impacts on environmental and human health have been raised. Poly(amidoamine) (PAMAM) dendrimers are specifically suitable for biomedical applications. They are well-defined nanoscale molecules which contain a 2-carbon ethylenediamine core and primary amine groups at the surface. The systematically variable structural architecture and the large internal free volume make these dendrimers an attractive option for drug delivery and other biomedical applications. Due to the wide range of applications, the Organisation for Economic Co-Operation and Development (OECD) have included them in their list of nanoparticles which require toxicological assessment. Thus, the toxicological impact of these PAMAM dendrimers on human health and the environment is a matter of concern. In this review, the potential toxicological impact of PAMAM dendrimers on human health and environment is assessed, highlighting work to date exploring the toxicological effects of PAMAM dendrimers. PMID- 29443904 TI - Comparison of Conventional and Microwave Assisted Heating on Carbohydrate Content, Antioxidant Capacity and Postprandial Glycemic Response in Oat Meals. AB - Minimally processed cereal breakfast products from whole grain entered the market due to consumer demand of more nutritional food with more controlled sugar release. However, the subsequent processing of such products with different cooking methods in the consumer's kitchen may lead to significant differentiation of their nutritional value. Therefore, the evaluation of the impact of frequently used cooking methods on a final quality of breakfast cereals meal is needed. The present study investigates how the two different methods of heating, conventional and microwave (MW) assisted, affect the carbohydrate content, profile and resulting glycemic index of so prepared food as well as the antioxidant activity of meals. Two products available on the market-oat bran and flakes-were used. The highest starch content in fluid phase of oatmeal was detected in samples heated for 3 min with microwaves, regardless the type. The lowest starch content was obtained for 5 min MW heated flakes sample. The total content of glucose was about 1.5 times lower in bran vs. flakes oatmeal. The highest beta-glucan content in fluid fraction was also observed for bran meal but its release was independent of applied conditions. PMID- 29443905 TI - A Comparison of Military and Law Enforcement Body Armour. AB - Law-enforcement officers increasingly wear body armour for protection; wearing body armour is common practice in military populations. Law-enforcement and military occupational demands are vastly different and military-styled body armour may not be suitable for law-enforcement. This study investigated differences between selected military body armour (MBA: 6.4 kg) and law enforcement body armour (LEBA: 2.1 kg) in impacts on postural sway, vertical jump, agility, a functional movement screen (FMS), task simulations (vehicle exit; victim recovery), and subjective measures. Ten volunteer police officers (six females, four males) were randomly allocated to one of the designs on each of two days. Body armour type did not significantly affect postural sway, vertical jump, vehicle exit and 5 m sprint times, or victim recovery times. Both armour types increased sway velocity and sway-path length in the final five seconds compared to the first 5 s of a balance task. The MBA was associated with significantly slower times to complete the agility task, poorer FMS total scores, and poorer subjective ratings of performance and comfort. The LEBA was perceived as more comfortable and received more positive performance ratings during the agility test and task simulations. The impacts of MBA and LEBA differed significantly and they should not be considered interchangeable. PMID- 29443906 TI - A Single RF Emitter-Based Indoor Navigation Method for Autonomous Service Robots. AB - Location-aware services are one of the key elements of modern intelligent applications. Numerous real-world applications such as factory automation, indoor delivery, and even search and rescue scenarios require autonomous robots to have the ability to navigate in an unknown environment and reach mobile targets with minimal or no prior infrastructure deployment. This research investigates and proposes a novel approach of dynamic target localisation using a single RF emitter, which will be used as the basis of allowing autonomous robots to navigate towards and reach a target. Through the use of multiple directional antennae, Received Signal Strength (RSS) is compared to determine the most probable direction of the targeted emitter, which is combined with the distance estimates to improve the localisation performance. The accuracy of the position estimate is further improved using a particle filter to mitigate the fluctuating nature of real-time RSS data. Based on the direction information, a motion control algorithm is proposed, using Simultaneous Localisation and Mapping (SLAM) and A* path planning to enable navigation through unknown complex environments. A number of navigation scenarios were developed in the context of factory automation applications to demonstrate and evaluate the functionality and performance of the proposed system. PMID- 29443907 TI - Bioactive Films Containing Alginate-Pectin Composite Microbeads with Lactococcus lactis subsp. lactis: Physicochemical Characterization and Antilisterial Activity. AB - Novel bioactive films were developed from the incorporation of Lactococcus lactis into polysaccharide films. Two different biopolymers were tested: cellulose derivative (hydroxylpropylmethylcellulose (HPMC)) and corn starch. Lactic acid bacteria (LAB) free or previously encapsulated in alginate-pectin composite hydrogel microbeads were added directly to the film forming solution and films were obtained by casting. In order to study the impact of the incorporation of the protective culture into the biopolymer matrix, the water vapour permeability, oxygen permeability, optical and mechanical properties of the dry films were evaluated. Furthermore, the antimicrobial effect of bioactive films against Listeria monocytogenes was studied in synthetic medium. Results showed that the addition of LAB or alginate-pectin microbeads modified slightly films optical properties. In comparison with HPMC films, starch matrix proves to be more sensitive to the addition of bacterial cells or beads. Indeed, mechanical resistance of corn starch films was lower but barrier properties were improved, certainly related to the possible establishment of interactions between alginate pectin beads and starch. HPMC and starch films containing encapsulated bioactive culture showed a complete inhibition of listerial growth during the first five days of storage at 5 degrees C and a reduction of 5 logs after 12 days. PMID- 29443910 TI - The Preparation and Optical Properties of Novel LiLa(MoO4)2:Sm3+,Eu3+ Red Phosphor. AB - Novel LiLa1-x-y(MoO4)2:xSm3+,yEu3+ (in short: LL1-x-yM:xSm3+,yEu3+) double molybdate red phosphors were synthesized by a solid-state reaction at as low temperature as 610 degrees C. The optimal doping concentration of Sm3+ in LiLa1 x(MoO4)2:xSm3+ (LL1-xM:xSm3+) phosphor is x = 0.05 and higher concentrations lead to emission quenching by the electric dipole-electric dipole mechanism. In the samples co-doped with Eu3+ ions, the absorption spectrum in the near ultraviolet and blue regions became broader and stronger than these of the Sm3+ single-doped samples. The efficient energy transfer from Sm3+ to Eu3+ was found and the energy transfer efficiency was calculated. Under the excitation at 403 nm, the chromaticity coordinates of LL0.95-yM:0.05Sm3+,yEu3+ approach to the NTSC standard values (0.670, 0.330) continuously with increasing Eu3+ doping concentration. The phosphor exhibits high luminous efficiency under near UV or blue light excitation and remarkable thermal stability. At 150 degrees C, the integrated emission intensity of the Eu3+ remained 85% of the initial intensity at room temperature and the activation energy is calculated to be 0.254 eV. The addition of the LL0.83M:0.05Sm3+,0.12Eu3+ red phosphors can improve the color purity and reduce the correlated color temperature of WLED lamps. Hence, LL1-x yM:xSm3+,yEu3+ is a promising WLED red phosphor. PMID- 29443908 TI - Mosquitoes as Suitable Vectors for Alphaviruses. AB - Alphaviruses are arthropod-borne viruses and are predominantly transmitted via mosquito vectors. This vector preference by alphaviruses raises the important question of the determinants that contribute to vector competence. There are several tissue barriers of the mosquito that the virus must overcome in order to establish a productive infection. Of importance are the midgut, basal lamina and the salivary glands. Infection of the salivary glands is crucial for virus transmission during the mosquito's subsequent bloodfeed. Other factors that may contribute to vector competence include the microflora and parasites present in the mosquito, environmental conditions, the molecular determinants of the virus to adapt to the vector, as well as the effect of co-infection with other viruses. Though mosquito innate immunity is a contributing factor to vector competence, it will not be discussed in this review. Detailed understanding of these factors will be instrumental in minimising transmission of alphaviral diseases. PMID- 29443909 TI - Identification of Bichalcones as Sirtuin Inhibitors by Virtual Screening and In Vitro Testing. AB - Sirtuins are nicotinamide adenine dinucleotide (NAD+)-dependent class III histone deacetylases, which have been linked to the pathogenesis of numerous diseases, including HIV, metabolic disorders, neurodegeneration and cancer. Docking of the virtual pan-African natural products library (p-ANAPL), followed by in vitro testing, resulted in the identification of two inhibitors of sirtuin 1, 2 and 3 (sirt1-3). Two bichalcones, known as rhuschalcone IV (8) and an analogue of rhuschalcone I (9), previously isolated from the medicinal plant Rhus pyroides, were shown to be active in the in vitro assay. The rhuschalcone I analogue (9) showed the best activity against sirt1, with an IC50 value of 40.8 uM. Based on the docking experiments, suggestions for improving the biological activities of the newly identified hit compounds have been provided.

AB - A series of novel 2,4-diaminoquinazoline derivatives were designed, synthesized, and evaluated as p21-activated kinase 4 (PAK4) inhibitors. All compounds showed significant inhibitory activity against PAK4 (half-maximal inhibitory concentration IC50 < 1 MUM). Among them, compounds 8d and 9c demonstrated the most potent inhibitory activity against PAK4 (IC50 = 0.060 MUM and 0.068 MUM, respectively). Furthermore, we observed that compounds 8d and 9c displayed potent antiproliferative activity against the A549 cell line and inhibited cell cycle distribution, migration, and invasion of this cell line. In addition, molecular docking analysis was performed to predict the possible binding mode of compound 8d. This series of compounds has the potential for further development as PAK4 inhibitors for anticancer activity. PMID- 29443912 TI - Influence of Scanning Strategies on Processing of Aluminum Alloy EN AW 2618 Using Selective Laser Melting. AB - This paper deals with various selective laser melting (SLM) processing strategies for aluminum 2618 powder in order to get material densities and properties close to conventionally-produced, high-strength 2618 alloy. To evaluate the influence of laser scanning strategies on the resulting porosity and mechanical properties a row of experiments was done. Three types of samples were used: single-track welds, bulk samples and samples for tensile testing. Single-track welds were used to find the appropriate processing parameters for achieving continuous and well shaped welds. The bulk samples were built with different scanning strategies with the aim of reaching a low relative porosity of the material. The combination of the chessboard strategy with a 2 * 2 mm field size fabricated with an out-in spiral order was found to eliminate a major lack of fusion defects. However, small cracks in the material structure were found over the complete range of tested parameters. The decisive criteria was the elimination of small cracks that drastically reduced mechanical properties. Reduction of the thermal gradient using support structures or fabrication under elevated temperatures shows a promising approach to eliminating the cracks. Mechanical properties of samples produced by SLM were compared with the properties of extruded material. The results showed that the SLM-processed 2618 alloy could only reach one half of the yield strength and tensile strength of extruded material. This is mainly due to the occurrence of small cracks in the structure of the built material. PMID- 29443913 TI - Development of Functional Phthalocyanine-Based Associate towards an Effective Fluorimetric Detection of Hg(II). AB - In acidic media, cationic phthalocyanine Alcian blue 8GX, has an efficient fluorescence quenching effect on anionic phthalocyanine tetrasulphoaluminium phthalocyanines (AlS4Pc), forming an almost non-fluorescent associate. Based on this discovery, a red-emitting fluorescent probe consisted of AlS4PC and Alcian blue 8GX has been developed through molecular assembly. Further studies indicated that the presence of Hg(II) ion has a significant fluorescence recovery effect of the probe. Notably, only Hg(II) can significantly restore the fluorescence of AlS4Pc-Alcian blue 8GX system which was revealed from the screening experiments of common metal ions, which confirmed that the fluorescence recovery by other metal ions is very weak or even unrestored, showing high specificity and sensitivity AlS4Pc-Alcian blue 8GX to Hg(II). Thus, a new fluorimetry for Hg(II) with high specificity and high sensitivity in a wide concentration range has been established using AlS4Pc-Alcian blue 8GX associate as a red-emitting fluorescent probe. It is more noteworthy that this study opens a new way for development and application of functional phthalocyanine based red-emitting fluorescent probes. PMID- 29443914 TI - Using Unmanned Aerial Vehicles in Postfire Vegetation Survey Campaigns through Large and Heterogeneous Areas: Opportunities and Challenges. AB - This study evaluated the opportunities and challenges of using drones to obtain multispectral orthomosaics at ultra-high resolution that could be useful for monitoring large and heterogeneous burned areas. We conducted a survey using an octocopter equipped with a Parrot SEQUOIA multispectral camera in a 3000 ha framework located within the perimeter of a megafire in Spain. We assessed the quality of both the camera raw imagery and the multispectral orthomosaic obtained, as well as the required processing capability. Additionally, we compared the spatial information provided by the drone orthomosaic at ultra-high spatial resolution with another image provided by the WorldView-2 satellite at high spatial resolution. The drone raw imagery presented some anomalies, such as horizontal banding noise and non-homogeneous radiometry. Camera locations showed a lack of synchrony of the single frequency GPS receiver. The georeferencing process based on ground control points achieved an error lower than 30 cm in X-Y and lower than 55 cm in Z. The drone orthomosaic provided more information in terms of spatial variability in heterogeneous burned areas in comparison with the WorldView-2 satellite imagery. The drone orthomosaic could constitute a viable alternative for the evaluation of post-fire vegetation regeneration in large and heterogeneous burned areas. PMID- 29443915 TI - Quantification of Stable Isotope Traces Close to Natural Enrichment in Human Plasma Metabolites Using Gas Chromatography-Mass Spectrometry. AB - Currently, changes in metabolic fluxes following consumption of stable isotope enriched foods are usually limited to the analysis of postprandial kinetics of glucose. Kinetic information on a larger diversity of metabolites is often lacking, mainly due to the marginal percentage of fully isotopically enriched plant material in the administered food product, and hence, an even weaker 13C enrichment in downstream plasma metabolites. Therefore, we developed an analytical workflow to determine weak 13C enrichments of diverse plasma metabolites with conventional gas chromatography-mass spectrometry (GC-MS). The limit of quantification was increased by optimizing (1) the metabolite extraction from plasma, (2) the GC-MS measurement, and (3) most importantly, the computational data processing. We applied our workflow to study the catabolic dynamics of 13C-enriched wheat bread in three human subjects. For that purpose, we collected time-resolved human plasma samples at 16 timepoints after the consumption of 13C-labeled bread and quantified 13C enrichment of 12 metabolites (glucose, lactate, alanine, glycine, serine, citrate, glutamate, glutamine, valine, isoleucine, tyrosine, and threonine). Based on isotopomer specific analysis, we were able to distinguish catabolic profiles of starch and protein hydrolysis. More generally, our study highlights that conventional GC-MS equipment is sufficient to detect isotope traces below 1% if an appropriate data processing is integrated. PMID- 29443916 TI - Mexican-Hat-Like Response in a Flexible Tactile Sensor Using a Magnetorheological Elastomer. AB - A significant challenge in robotics is providing a sense of touch to robots. Even though several types of flexible tactile sensors have been proposed, they still have various technical issues such as a large amount of deformation that fractures the sensing elements, a poor maintainability and a deterioration in the sensitivity caused by the presence of a thick and soft covering. As one solution for these issues, we proposed a flexible tactile sensor composed of a magnet, magnetic transducer and dual-layer elastomer, which consists of a magnetorheological and nonmagnetic elastomer sheet. In this study, we first investigated the sensitivity of the sensor, which was found to be high (approximately 161 mV/N with a signal-to-noise ratio of 42.2 dB); however, the sensor has a speed-dependent hysteresis in its sensor response curve. Then, we investigated the spatial response and observed the following results: (1) the sensor response was a distorted Mexican-hat-like bipolar shape, namely a negative response area was observed around the positive response area; (2) the negative response area disappeared when we used a compressible sponge sheet instead of the incompressible nonmagnetic elastomer. We concluded that the characteristic negative response in the Mexican-hat-like response is derived from the incompressibility of the nonmagnetic elastomer. PMID- 29443917 TI - Detection of Thrombin Based on Fluorescence Energy Transfer between Semiconducting Polymer Dots and BHQ-Labelled Aptamers. AB - Carboxyl-functionalized semiconducting polymer dots (Pdots) were synthesized as an energy donor by the nanoprecipitation method. A black hole quenching dye (BHQ labelled thrombin aptamers) was used as the energy acceptor, and fluorescence resonance energy transfer between the aptamers and Pdots was used for fluorescence quenching of the Pdots. The addition of thrombin restored the fluorescence intensity. Under the optimized experimental conditions, the fluorescence of the system was restored to the maximum when the concentration of thrombin reached 130 nM, with a linear range of 0-50 nM (R2 = 0.990) and a detection limit of 0.33 nM. This sensor was less disturbed by impurities, showing good specificity and signal response to thrombin, with good application in actual samples. The detection of human serum showed good linearity in the range of 0-30 nM (R2 = 0.997), with a detection limit of 0.56 nM and a recovery rate of 96.2 104.1%, indicating that this fluorescence sensor can be used for the detection of thrombin content in human serum. PMID- 29443918 TI - Error Modelling for Multi-Sensor Measurements in Infrastructure-Free Indoor Navigation. AB - The long-term objective of our research is to develop a method for infrastructure free simultaneous localization and mapping (SLAM) and context recognition for tactical situational awareness. Localization will be realized by propagating motion measurements obtained using a monocular camera, a foot-mounted Inertial Measurement Unit (IMU), sonar, and a barometer. Due to the size and weight requirements set by tactical applications, Micro-Electro-Mechanical (MEMS) sensors will be used. However, MEMS sensors suffer from biases and drift errors that may substantially decrease the position accuracy. Therefore, sophisticated error modelling and implementation of integration algorithms are key for providing a viable result. Algorithms used for multi-sensor fusion have traditionally been different versions of Kalman filters. However, Kalman filters are based on the assumptions that the state propagation and measurement models are linear with additive Gaussian noise. Neither of the assumptions is correct for tactical applications, especially for dismounted soldiers, or rescue personnel. Therefore, error modelling and implementation of advanced fusion algorithms are essential for providing a viable result. Our approach is to use particle filtering (PF), which is a sophisticated option for integrating measurements emerging from pedestrian motion having non-Gaussian error characteristics. This paper discusses the statistical modelling of the measurement errors from inertial sensors and vision based heading and translation measurements to include the correct error probability density functions (pdf) in the particle filter implementation. Then, model fitting is used to verify the pdfs of the measurement errors. Based on the deduced error models of the measurements, particle filtering method is developed to fuse all this information, where the weights of each particle are computed based on the specific models derived. The performance of the developed method is tested via two experiments, one at a university's premises and another in realistic tactical conditions. The results show significant improvement on the horizontal localization when the measurement errors are carefully modelled and their inclusion into the particle filtering implementation correctly realized. PMID- 29443919 TI - A Novel Strategy for Very-Large-Scale Cash-Crop Mapping in the Context of Weather Related Risk Assessment, Combining Global Satellite Multispectral Datasets, Environmental Constraints, and In Situ Acquisition of Geospatial Data. AB - Cash crops are agricultural crops intended to be sold for profit as opposed to subsistence crops, meant to support the producer, or to support livestock. Since cash crops are intended for future sale, they translate into large financial value when considered on a wide geographical scale, so their production directly involves financial risk. At a national level, extreme weather events including destructive rain or hail, as well as drought, can have a significant impact on the overall economic balance. It is thus important to map such crops in order to set up insurance and mitigation strategies. Using locally generated data-such as municipality-level records of crop seeding-for mapping purposes implies facing a series of issues like data availability, quality, homogeneity, etc. We thus opted for a different approach relying on global datasets. Global datasets ensure homogeneity and availability of data, although sometimes at the expense of precision and accuracy. A typical global approach makes use of spaceborne remote sensing, for which different land cover classification strategies are available in literature at different levels of cost and accuracy. We selected the optimal strategy in the perspective of a global processing chain. Thanks to a specifically developed strategy for fusing unsupervised classification results with environmental constraints and other geospatial inputs including ground-based data, we managed to obtain good classification results despite the constraints placed. The overall production process was composed using "good-enough" algorithms at each step, ensuring that the precision, accuracy, and data-hunger of each algorithm was commensurate to the precision, accuracy, and amount of data available. This paper describes the tailored strategy developed on the occasion as a cooperation among different groups with diverse backgrounds, a strategy which is believed to be profitably reusable in other, similar contexts. The paper presents the problem, the constraints and the adopted solutions; it then summarizes the main findings including that efforts and costs can be saved on the side of Earth Observation data processing when additional ground-based data are available to support the mapping task. PMID- 29443920 TI - Gradient-Type Magnetoelectric Current Sensor with Strong Multisource Noise Suppression. AB - A novel gradient-type magnetoelectric (ME) current sensor operating in magnetic field gradient (MFG) detection and conversion mode is developed based on a pair of ME composites that have a back-to-back capacitor configuration under a baseline separation and a magnetic biasing in an electrically-shielded and mechanically-enclosed housing. The physics behind the current sensing process is the product effect of the current-induced MFG effect associated with vortex magnetic fields of current-carrying cables (i.e., MFG detection) and the MFG induced ME effect in the ME composite pair (i.e., MFG conversion). The sensor output voltage is directly obtained from the gradient ME voltage of the ME composite pair and is calibrated against cable current to give the current sensitivity. The current sensing performance of the sensor is evaluated, both theoretically and experimentally, under multisource noises of electric fields, magnetic fields, vibrations, and thermals. The sensor combines the merits of small nonlinearity in the current-induced MFG effect with those of high sensitivity and high common-mode noise rejection rate in the MFG-induced ME effect to achieve a high current sensitivity of 0.65-12.55 mV/A in the frequency range of 10 Hz-170 kHz, a small input-output nonlinearity of <500 ppm, a small thermal drift of <0.2%/C in the current range of 0-20 A, and a high common-mode noise rejection rate of 17-28 dB from multisource noises. PMID- 29443921 TI - Calcium Chloride and Calcium Gluconate in Neonatal Parenteral Nutrition Solutions without Cysteine: Compatibility Studies Using Laser Light Obscuration Methodology. AB - There are no compatibility studies for neonatal parenteral nutrition solutions without cysteine containing calcium chloride or calcium gluconate using light obscuration as recommended by the United States Pharmacopeia (USP). The purpose of this study was to do compatibility testing for solutions containing calcium chloride and calcium gluconate without cysteine. Solutions of TrophAmine and Premasol (2.5% amino acids), containing calcium chloride or calcium gluconate were compounded without cysteine. Solutions were analyzed for particle counts using light obscuration. Maximum concentrations tested were 15 mmol/L of calcium and 12.5 mmol/L of phosphate. If the average particle count of three replicates exceeded USP guidelines, the solution was determined to be incompatible. This study found that 12.5 and 10 mmol/L of calcium and phosphate, respectively, are compatible in neonatal parenteral nutrition solutions compounded with 2.5% amino acids of either TrophAmine or Premasol. There did not appear to be significant differences in compatibility for solutions containing TrophAmine or Premasol when solutions were compounded with either CaCl2 or CaGlu-Pl. This study presents data in order to evaluate options for adding calcium and phosphate to neonatal parenteral nutrition solutions during shortages of calcium and cysteine. PMID- 29443923 TI - On the Comparison of Wearable Sensor Data Fusion to a Single Sensor Machine Learning Technique in Fall Detection. AB - In the context of the ageing global population, researchers and scientists have tried to find solutions to many challenges faced by older people. Falls, the leading cause of injury among elderly, are usually severe enough to require immediate medical attention; thus, their detection is of primary importance. To this effect, many fall detection systems that utilize wearable and ambient sensors have been proposed. In this study, we compare three newly proposed data fusion schemes that have been applied in human activity recognition and fall detection. Furthermore, these algorithms are compared to our recent work regarding fall detection in which only one type of sensor is used. The results show that fusion algorithms differ in their performance, whereas a machine learning strategy should be preferred. In conclusion, the methods presented and the comparison of their performance provide useful insights into the problem of fall detection. PMID- 29443922 TI - Effects of an Acute Exercise Bout on Serum Hepcidin Levels. AB - Iron deficiency is a frequent and multifactorial disorder in the career of athletes, particularly in females. Exercise-induced disturbances in iron homeostasis produce deleterious effects on performance and adaptation to training; thus, the identification of strategies that restore or maintain iron homeostasis in athletes is required. Hepcidin is a liver-derived hormone that degrades the ferroportin transport channel, thus reducing the ability of macrophages to recycle damaged iron, and decreasing iron availability. Although it has been suggested that the circulating fraction of hepcidin increases during early post-exercise recovery (~3 h), it remains unknown how an acute exercise bout may modify the circulating expression of hepcidin. Therefore, the current review aims to determine the post-exercise expression of serum hepcidin in response to a single session of exercise. The review was carried out in the Dialnet, Elsevier, Medline, Pubmed, Scielo and SPORTDiscus databases, using hepcidin (and "exercise" or "sport" or "physical activity") as a strategy of search. A total of 19 articles were included in the review after the application of the inclusion/exclusion criteria. This search found that a single session of endurance exercise (intervallic or continuous) at moderate or vigorous intensity (60-90% VO2peak) stimulates an increase in the circulating levels of hepcidin between 0 h and 6 h after the end of the exercise bout, peaking at ~3 h post exercise. The magnitude of the response of hepcidin to exercise seems to be dependent on the pre-exercise status of iron (ferritin) and inflammation (IL-6). Moreover, oxygen disturbances and the activation of a hypoxia-induced factor during or after exercise may stimulate a reduction of hepcidin expression. Meanwhile, cranberry flavonoids supplementation promotes an anti-oxidant effect that may facilitate the post-exercise expression of hepcidin. Further studies are required to explore the effect of resistance exercise on hepcidin expression.

Though many efforts have been made to elucidate the process of HCC, its molecular mechanisms of development remain elusive due to its complexity. To explore the stepwise carcinogenic process from pre-neoplastic lesions to the end stage of HCC, we employed weighted gene co-expression network analysis (WGCNA) which has been proved to be an effective method in many diseases to detect co-expressed modules and hub genes using eight pathological stages including normal, cirrhosis without HCC, cirrhosis, low-grade dysplastic, high-grade dysplastic, very early and early, advanced HCC and very advanced HCC. Among the eight consecutive pathological stages, five representative modules are selected to perform canonical pathway enrichment and upstream regulator analysis by using ingenuity pathway analysis (IPA) software. We found that cell cycle related biological processes were activated at four neoplastic stages, and the degree of activation of the cell cycle corresponded to the deterioration degree of HCC. The orange and yellow modules enriched in energy metabolism, especially oxidative metabolism, and the expression value of the genes decreased only at four neoplastic stages. The brown module, enriched in protein ubiquitination and ephrin receptor signaling pathways, correlated mainly with the very early stage of HCC. The darkred module, enriched in hepatic fibrosis/hepatic stellate cell activation, correlated with the cirrhotic stage only. The high degree hub genes were identified based on the protein-protein interaction (PPI) network and were verified by Kaplan-Meier survival analysis. The novel five high degree hub genes signature that was identified in our study may shed light on future prognostic and therapeutic approaches. Our study brings a new perspective to the understanding of the key pathways and genes in the dynamic changes of HCC progression. These findings shed light on further investigations. PMID- 29443925 TI - PClass: Protein Quaternary Structure Classification by Using Bootstrapping Strategy as Model Selection. AB - Protein quaternary structure complex is also known as a multimer, which plays an important role in a cell. The dimer structure of transcription factors is involved in gene regulation, but the trimer structure of virus-infection associated glycoproteins is related to the human immunodeficiency virus. The classification of the protein quaternary structure complex for the post-genome era of proteomics research will be of great help. Classification systems among protein quaternary structures have not been widely developed. Therefore, we designed the architecture of a two-layer machine learning technique in this study, and developed the classification system PClass. The protein quaternary structure of the complex is divided into five categories, namely, monomer, dimer, trimer, tetramer, and other subunit classes. In the framework of the bootstrap method with a support vector machine, we propose a new model selection method. Each type of complex is classified based on sequences, entropy, and accessible surface area, thereby generating a plurality of feature modules. Subsequently, the optimal model of effectiveness is selected as each kind of complex feature module. In this stage, the optimal performance can reach as high as 70% of Matthews correlation coefficient (MCC). The second layer of construction combines the first-layer module to integrate mechanisms and the use of six machine learning methods to improve the prediction performance. This system can be improved over 10% in MCC. Finally, we analyzed the performance of our classification system using transcription factors in dimer structure and virus infection-associated glycoprotein in trimer structure. PClass is available via a web interface at http://predictor.nchu.edu.tw/PClass/. PMID- 29443926 TI - The Pleiotropic Effects of the Canonical Wnt Pathway in Early Development and Pluripotency. AB - The technology to derive embryonic and induced pluripotent stem cells from early embryonic stages and adult somatic cells, respectively, emerged as a powerful resource to enable the establishment of new in vitro models, which recapitulate early developmental processes and disease. Additionally, pluripotent stem cells (PSCs) represent an invaluable source of relevant differentiated cell types with immense potential for regenerative medicine and cell replacement therapies. Pluripotent stem cells support self-renewal, potency and proliferation for extensive periods of culture in vitro. However, the core pathways that rule each of these cellular features specific to PSCs only recently began to be clarified. The Wnt signaling pathway is pivotal during early embryogenesis and is central for the induction and maintenance of the pluripotency of PSCs. Signaling by the Wnt family of ligands is conveyed intracellularly by the stabilization of beta catenin in the cytoplasm and in the nucleus, where it elicits the transcriptional activity of T-cell factor (TCF)/lymphoid enhancer factor (LEF) family of transcription factors. Interestingly, in PSCs, the Wnt/beta-catenin-TCF/LEF axis has several unrelated and sometimes opposite cellular functions such as self renewal, stemness, lineage commitment and cell cycle regulation. In addition, tight control of the Wnt signaling pathway enhances reprogramming of somatic cells to induced pluripotency. Several recent research efforts emphasize the pleiotropic functions of the Wnt signaling pathway in the pluripotent state. Nonetheless, conflicting results and unanswered questions still linger. In this review, we will focus on the diverse functions of the canonical Wnt signaling pathway on the developmental processes preceding embryo implantation, as well as on its roles in pluripotent stem cell biology such as self-renewal and cell cycle regulation and somatic cell reprogramming.

AB - In recent years, luminogens with the feature of aggregation-induced emission (AIEgen) have emerged as advanced luminescent materials for fluorescent nanomaterial preparation. AIEgen-based nanomaterials show enhanced fluorescence efficiency and superior photostability, which thusly offer unique advantages in biological applications. In this review, we will summarize the fabrication methods of AIEgen-based nanomaterials and their applications in in vitro/in vivo imaging, cell tracing, photodynamic therapy and drug delivery, focusing on the recent progress. PMID- 29443928 TI - Changes in the Anti-Allergic Activities of Sesame by Bioconversion. AB - Sesame is an important oilseed crop, which has been used as a traditional health food to ameliorate the prevention of various diseases. We evaluated the changes in the anti-allergic activities of sesame by bioconversion. SDS-PAGE of non fermented sesame proteins showed major allergen bands, while that of fermented sesame showed only a few protein bands. Additionally, we investigated the effectiveness of fermented sesame by bioconversion in tumor necrosis factor-alpha (TNF-alpha)- and interferon-gamma (IFN-gamma)-induced HaCaT cells. In HaCaT cells, fermented sesame inhibited the mRNA expression of interleukin-6 (IL-6) and interleukin-1beta (IL-1beta), thymus and macrophage-derived chemokine (MDC/CCL22), activation-regulated chemokine (TARC/CCL17), and intercellular adhesion molecule-1 (ICAM-1). Moreover, fermented sesame inhibited the activation of nuclear factor-kappaB (NF-kappaB) and signal transducer and activator of transcription 1 (STAT1). Fermented sesame exerts anti-allergic effects by suppressing the expression of chemokines and cytokines via blockade of NF-kappaB and STAT1 activation. PMID- 29443931 TI - Robust Automatic Target Recognition via HRRP Sequence Based on Scatterer Matching. AB - High resolution range profile (HRRP) plays an important role in wideband radar automatic target recognition (ATR). In order to alleviate the sensitivity to clutter and target aspect, employing a sequence of HRRP is a promising approach to enhance the ATR performance. In this paper, a novel HRRP sequence-matching method based on singular value decomposition (SVD) is proposed. First, the HRRP sequence is decoupled into the angle space and the range space via SVD, which correspond to the span of the left and the right singular vectors, respectively. Second, atomic norm minimization (ANM) is utilized to estimate dominant scatterers in the range space and the Hausdorff distance is employed to measure the scatter similarity between the test and training data. Next, the angle space similarity between the test and training data is evaluated based on the left singular vector correlations. Finally, the range space matching result and the angle space correlation are fused with the singular values as weights. Simulation and outfield experimental results demonstrate that the proposed matching metric is a robust similarity measure for HRRP sequence recognition. PMID- 29443929 TI - Claimed Effects, Outcome Variables and Methods of Measurement for Health Claims on Foods Related to Vision Proposed Under Regulation (EC) 1924/2006. AB - Adequate visual function has a strong impact on the quality of life of people. Several foods and food components have been hypothesized to play a role in the maintenance of normal visual function and in the prevention of eye diseases. Some of these foods/food components have been the object of a request of authorization for use of health claims under Articles 13(5) or 14 of the Regulation (EC) 1924/2006. Most of these requests have received a negative opinion from the European Food Safety Authority (EFSA) due to the choice of inappropriate outcome variables (OVs) and/or methods of measurement (MMs) applied in the studies used to substantiate the claims. This manuscript refers to the collection, collation and critical analysis of OVs and MMs related to vision. Guidance document and requests for authorization of health claims were used to collect OVs and MMs related to vision. A literature review was performed to critically analyse OVs and MMs, with the aim of defining their appropriateness in the context of a specific claimed effect related to vision. The results highlight the importance of adequate choices of OVs and MMs for an effective substantiation of claims related to visual function. PMID- 29443930 TI - Imbalanced Nutrient Intake in Cancer Survivors from the Examination from the Nationwide Health Examination Center-Based Cohort. AB - This study was conducted to examine the nutrient intake status of cancer survivors. A total of 5224 cancer survivors, 19,926 non-cancer individuals without comorbidities (non-cancer I), and 20,622 non-cancer individuals with comorbidities, matched by age, gender, and recruitment center location were included in the analysis. Generally, the proportion of total energy from carbohydrates was higher and the proportion from fat was lower in cancer survivors. The odds ratios (ORs) for total energy (OR = 0.92, 95% confidence interval (CI) = 0.86-0.99), proportion of total energy from fat (OR = 0.54, 95% CI = 0.35-0.83), and protein (OR = 0.85, 95% CI = 0.79-0.90) were significantly lower, and the OR for the proportion of total energy from carbohydrates was higher (OR = 1.21, 95% CI = 1.10-1.33) in the cancer survivors than in non-cancer I. Additionally, the cancer survivors' protein, vitamin B1, vitamin B2, niacin, and phosphorus intakes were lower, whereas their vitamin C intake was higher. When divided by cancer type, the ORs for the carbohydrate percentages were significantly higher in the colon and breast cancer survivors, whereas protein intake was lower in gastric, breast, and cervical cancer survivors. The nutrient intake patterns in Asian cancer survivors are poor, with higher carbohydrate and lower fat and protein intakes. PMID- 29443932 TI - Relationships between Characteristics of Urban Green Land Cover and Mental Health in U.S. Metropolitan Areas. AB - Urbanization increases risk for depression and other mental disorders. A growing body of research indicates the natural environment confers numerous psychological benefits including alleviation of mental distress. This study examined land cover types and landscape metrics in relation to mental health for 276 U.S. counties within metropolitan areas having a population of 1 million or more. County Health Rankings and Behavioral Risk and Factor Surveillance System (BRFSS) provided a measure of mental health. The 2011 National Land Cover Database (NLCD) provided data on green land cover types, from which seven landscape metrics were generated to characterize landscape patterns. Spearman's rho correlation and stepwise logistic regression models, respectively, were employed to examine bivariate and multivariate relationships. Models were adjusted for county population and housing density, region, race, and income to account for potential confounding. Overall, individual measures of landscape patterns showed stronger associations with mental health than percent total cover alone. Greater edge contrast was associated with 3.81% lower odds of Frequent Mental Distress (FMD) (Adjusted Odd's Ratio (AOR) = 0.9619, 95% CI = 0.9371, 0.9860). Shrubland cohesion was associated with greater odds of FMD (AOR = 1.0751, 95% CI = 1.0196, 1.1379). In addition, distance between shrubland cover was associated with greater odds of FMD (AOR = 1.0027, 95% CI = 1.0016, 1.0041). Although effect sizes were small, findings suggest different types of landscape characteristics may have different roles in improving mental health. PMID- 29443933 TI - Mental Health Interventions for Parent Carers of Children with Autistic Spectrum Disorder: Practice Guidelines from a Critical Interpretive Synthesis (CIS) Systematic Review. AB - Parent carers of children with Autism Spectrum Disorder (ASD) often report increased levels of stress, depression, and anxiety. Unmet parent carer mental health needs pose a significant risk to the psychological, physical, and social well-being of the parents of the child affected by ASD and jeopardize the adaptive functioning of the family as well as the potential of the child affected by ASD. This systematic review identifies key qualities of interventions supporting the mental health of parent carers and proposes practitioner-parent carer support guidelines. A search of four databases (Medline, PubMed, PsycINFO, and Social Science Data) was conducted to identify studies that met the following criteria: (1) an intervention was delivered to parent carers of a child with ASD under the age of 18 years; (2) the research design allowed for a comparison on outcomes across groups; and (3) outcome measures of the parent carers' mental health were used. A total of 23 studies met the inclusion criteria. A critical interpretive synthesis approach was used to produce an integrated conceptualization of the evidence. Findings suggest practitioner guidelines to support the mental health and wellbeing of parent carers should include addressing the parent's self-perspective taking and skill for real time problem solving. PMID- 29443934 TI - Half-Sandwich Ru(II) and Os(II) Bathophenanthroline Complexes Containing a Releasable Dichloroacetato Ligand. AB - We report on the preparation and thorough characterization of cytotoxic half sandwich complexes [Ru(eta6-pcym)(bphen)(dca)]PF6 (Ru-dca) and [Os(eta6 pcym)(bphen)(dca)]PF6 (Os-dca) containing dichloroacetate(1-) (dca) as the releasable O-donor ligand bearing its own cytotoxicity; pcym = 1-methyl-4-(propan 2-yl)benzene (p-cymene), bphen = 4,7-diphenyl-1,10-phenanthroline (bathophenanthroline). Complexes Ru-dca and Os-dca hydrolyzed in the water containing media, which led to the dca ligand release (supported by 1H NMR and electrospray ionization mass spectra). Mass spectrometry studies revealed that complexes Ru-dca and Os-dca do not interact covalently with the model proteins cytochrome c and lysozyme. Both complexes exhibited slightly higher in vitro cytotoxicity (IC50 = 3.5 MUM for Ru-dca, and 2.6 MUM for Os-dca) against the A2780 human ovarian carcinoma cells than cisplatin (IC50 = 5.9 MUM), while their toxicity on the healthy human hepatocytes was found to be IC50 = 19.1 MUM for Ru dca and IC50 = 19.7 MUM for Os-dca. Despite comparable cytotoxicity of complexes Ru-dca and Os-dca, both the complexes modified the cell cycle, mitochondrial membrane potential, and mitochondrial cytochrome c release by a different way, as revealed by flow cytometry experiments. The obtained results point out the different mechanisms of action between the complexes. PMID- 29443935 TI - Modulation of Donor-Acceptor Distance in a Series of Carbazole Push-Pull Dyes; A Spectroscopic and Computational Study. AB - A series of eight carbazole-cyanoacrylate based donor-acceptor dyes were studied. Within the series the influence of modifying the thiophene bridge, linking donor and acceptor and a change in the nature of the acceptor, from acid to ester, was explored. In this joint experimental and computational study we have used electronic absorbance and emission spectroscopies, Raman spectroscopy and computational modeling (density functional theory). From these studies it was found that extending the bridge length allowed the lowest energy transition to be systematically red shifted by 0.12 eV, allowing for limited tuning of the absorption of dyes using this structural motif. Using the aforementioned techniques we demonstrate that this transition is charge transfer in nature. Furthermore, the extent of charge transfer between donor and acceptor decreases with increasing bridge length and the bridge plays a smaller role in electronically mixing with the acceptor as it is extended. PMID- 29443937 TI - PCR Diagnosis of Small Hive Beetles. AB - Small hive beetles (SHBs), Aethinatumida, are parasites of social bee colonies native to sub-Saharan Africa and have become an invasive species at a global scale. Reliable Polymerase Chain Reaction (PCR) diagnosis of this mandatory pest is required to limit its further spread and impact. Here, we have developed SHB primers, which amplify for 10 native African locations and 10 reported introductions, but not for three closely related species (Aethinaconcolor, Aethinaflavicollis, and Aethinainconspicua). We also show that adult honey bee workers can be used as matrices for PCR-based detection of SHBs. The sensitivity of this novel method appears to be 100%, which is identical to conventional visual screenings. Furthermore, the specificity of this novel approach was also high (90.91%). Since both sensitivity and specificity are high, we recommend this novel PCR method and the new primers for routine surveillance of hives in high risk areas. PMID- 29443936 TI - Ageing with HIV. AB - The population of people living with HIV (PLWH) is growing older with an estimated 4 million over the age of 50 years, a figure which has doubled since the introduction of effective antiretroviral therapy (ART) and which is increasing globally. Despite effective ART, PLWH still experience excess morbidity and mortality compared to the general population with increased prevalence of age-related, non-AIDS illnesses (NAI) such as cardiovascular disease, malignancies, cognitive impairment and reduced bone mineral density, which impact disability and everyday functioning. This review will discuss the challenges presented by comorbidities in ageing PLWH and discuss the aetiology and management of age-related illnesses in this vulnerable population. PMID- 29443939 TI - Occurrence of beta-N-methylamino-l-alanine (BMAA) and Isomers in Aquatic Environments and Aquatic Food Sources for Humans. AB - The neurotoxin beta-N-methylamino-l-alanine (BMAA), a non-protein amino acid produced by terrestrial and aquatic cyanobacteria and by micro-algae, has been suggested to play a role as an environmental factor in the neurodegenerative disease Amyotrophic Lateral Sclerosis-Parkinsonism-Dementia complex (ALS-PDC). The ubiquitous presence of BMAA in aquatic environments and organisms along the food chain potentially makes it public health concerns. However, the BMAA associated human health risk remains difficult to rigorously assess due to analytical challenges associated with the detection and quantification of BMAA and its natural isomers, 2,4-diamino butyric acid (DAB), beta-amino-N-methyl alanine (BAMA) and N-(2-aminoethyl) glycine (AEG). This systematic review, reporting the current knowledge on the presence of BMAA and isomers in aquatic environments and human food sources, was based on a selection and a score numbering of the scientific literature according to various qualitative and quantitative criteria concerning the chemical analytical methods used. Results from the best-graded studies show that marine bivalves are to date the matrix containing the higher amount of BMAA, far more than most fish muscles, but with an exception for shark cartilage. This review discusses the available data in terms of their use for human health risk assessment and identifies knowledge gaps requiring further investigations. PMID- 29443938 TI - The Microbial Zoo in the C. elegans Intestine: Bacteria, Fungi and Viruses. AB - C. elegans is an invaluable model organism that has been a driving force in many fundamental biological discoveries. However, it is only in the past two decades that it has been applied to host-pathogen interaction studies. These studies have been facilitated by the discoveries of natural microbes that infect C. elegans, including bacteria, fungi and viruses. Notably, many of these microbes share a common site of infection, the C. elegans intestine. Furthermore, the recent descriptions of a natural gut microbiota in C. elegans raise the possibility that this could be a novel model system for microbiome and trans-kingdom interaction studies. Here we review studies of C. elegans host-microbe interactions with a particular focus on the intestine. PMID- 29443940 TI - Proteomic Differences in Feline Fibrosarcomas Grown Using Doxorubicin-Sensitive and -Resistant Cell Lines in the Chick Embryo Model. AB - Proteomic analyses are rapid and powerful tools that are used to increase the understanding of cancer pathogenesis, discover cancer biomarkers and predictive markers, and select and monitor novel targets for cancer therapy. Feline injection-site sarcomas (FISS) are aggressive skin tumours with high recurrence rates, despite treatment with surgery, radiotherapy, and chemotherapy. Doxorubicin is a drug of choice for soft tissue sarcomas, including FISS. However, multidrug resistance is one of the major causes of chemotherapy failure. The main aim of the present study was to identify proteins that differentiate doxorubicin-resistant from doxorubicin-sensitive FISS using two-dimensional gel electrophoresis (2DE), followed by matrix-assisted laser desorption ionisation time-of-flight mass spectrometry (MALDI-TOF MS) analysis. Using the three dimensional (3D) preclinical in ovo model, which resembles features of spontaneous fibrosarcomas, three significantly (p <= 0.05) differentially expressed proteins were identified in tumours grown from doxorubicin-resistant fibrosarcoma cell lines (FFS1 and FFS3) in comparison to the doxorubicin sensitive one (FFS5): Annexin A5 (ANXA5), Annexin A3 (ANXA3), and meiosis specific nuclear structural protein 1 (MNS1). Moreover, nine other proteins were significantly differentially expressed in tumours grown from the high doxorubicin resistant cell line (FFS1) in comparison to sensitive one (FFS5). This study may be the first proteomic fingerprinting of FISS reported, identifying potential candidates for specific predictive biomarkers and research targets for doxorubicin-resistant FISS. PMID- 29443941 TI - Cytokeratin-8 in Anaplastic Thyroid Carcinoma: More Than a Simple Structural Cytoskeletal Protein. AB - Anaplastic thyroid carcinoma (ATC) is almost universally fatal. Elevated keratin 8 (KRT8) protein expression is an established diagnostic cancer biomarker in several epithelial cancers (but not ATC). Several keratins, including KRT8, have been suggested to have a role in cell biology beyond that of structural cytoskeletal proteins. Here, we provide evidence that KRT8 plays a direct role in the growth of ATCs. Genomic and transcriptomic analysis of >5000 patients demonstrates that KRT8 mutation and copy number amplification are frequently evident in epithelial-derived cancers. Carcinomas arising from diverse tissues exhibit KRT8 mRNA and protein overexpression when compared to normal tissue levels. Similarly, in a panel of patient-derived ATC cell lines and patient tumors, KRT8 expression shows a similar pattern. sh-RNA-mediated KRT8 knockdown in these cell lines increases apoptosis, whereas forced overexpression of KRT8 confers resistance to apoptosis under peroxide-induced cell stress conditions. We further show that KRT8 protein binds to annexin A2, a protein known to mediate apoptosis as well as the redox pathway. PMID- 29443942 TI - Understanding the Effect of Particle Size and Processing on Almond Lipid Bioaccessibility through Microstructural Analysis: From Mastication to Faecal Collection. AB - We have previously reported on the low lipid bioaccessibility from almond seeds during digestion in the upper gastrointestinal tract (GIT). In the present study, we quantified the lipid released during artificial mastication from four almond meals: natural raw almonds (NA), roasted almonds (RA), roasted diced almonds (DA) and almond butter from roasted almonds (AB). Lipid release after mastication (8.9% from NA, 11.8% from RA, 12.4% from DA and 6.2% from AB) was used to validate our theoretical mathematical model of lipid bioaccessibility. The total lipid potentially available for digestion in AB was 94.0%, which included the freely available lipid resulting from the initial sample processing and the further small amount of lipid released from the intact almond particles during mastication. Particle size distributions measured after mastication in NA, RA and DA showed most of the particles had a size of 1000 um and above, whereas AB bolus mainly contained small particles (<850 um). Microstructural analysis of faecal samples from volunteers consuming NA, RA, DA and AB confirmed that some lipid in NA, RA and DA remained encapsulated within the plant tissue throughout digestion, whereas almost complete digestion was observed in the AB sample. We conclude that the structure and particle size of the almond meals are the main factors in regulating lipid bioaccessibility in the gut. PMID- 29443943 TI - A Comparative Study on Asymmetric Reduction of Ketones Using the Growing and Resting Cells of Marine-Derived Fungi. AB - Whole-cell biocatalysts offer a highly enantioselective, minimally polluting route to optically active alcohols. Currently, most of the whole-cell catalytic performance involves resting cells rather than growing cell biotransformation, which is one-step process that benefits from the simultaneous growth and biotransformation, eliminating the need for catalysts preparation. In this paper, asymmetric reduction of 14 aromatic ketones to the corresponding enantiomerically pure alcohols was successfully conducted using the growing and resting cells of marine-derived fungi under optimized conditions. Good yields and excellent enantioselectivities were achieved with both methods. Although substrate inhibition might be a limiting factor for growing cell biotransformation, the selected strain can still completely convert 10-mM substrates into the desired products. The resting cell biotransformation showed a capacity to be recycled nine times without a significant decrease in the activity. This is the first study to perform asymmetric reduction of ketones by one-step growing cell biotransformation. PMID- 29443944 TI - Differential Expression of Six Rnase2 and Three Rnase3 Paralogs Identified in Blunt Snout Bream in Response to Aeromonas hydrophila Infection. AB - Ribonucleases (Rnases)2 and Rnase3 belong to the ribonuclease A (RnaseA) superfamily. Apart from their role in molecular evolutionary and functional biological studies, these genes have also been studied in the context of defense against pathogen infection in mammals. However, expression patterns, structures and response to bacterial infection of the two genes in blunt snout bream (Megalobrama amblycephala) remain unknown. In this study, we identified multiple copies of Rnase2 (six) and Rnase3 (three) in the M. amblycephala genome. The nine genes all possess characteristics typical of the RnaseA superfamily. No expression was detected in the early developmental stages, while a weak expression was observed at 120 and 140 h post-fertilization (hpf) for Rnase2b, Rnase2c, Rnase2e and Rnase3a, suggesting that only three copies of Rnase2 and one of Rnase3 are expressed. Interestingly, only Rnase2e was up-regulated in the kidney of M. amblycephala after Aeromonas hydrophila infection, while Rnase3a was significantly up-regulated in liver, gut and blood after the infection. We conclude that the paralogs of Rnase3 are more susceptible to A. hydrophila infection than Rnase2. These results indicate that different Rnase2 and Rnase3 paralogs suggest a role in the innate immune response of M. amblycephala to bacterial infection. PMID- 29443945 TI - Charged N-terminus of Influenza Fusion Peptide Facilitates Membrane Fusion. AB - Cleavage of hemagglutinin precursor (HA0) by cellular proteases results in the formation of two subunits, HA1 and HA2. The N-terminal fragment of HA2, named a fusion peptide (HAfp), possess a charged, amine N-terminus. It has been shown that the N-terminus of HAfp stabilizes the structure of a helical hairpin observed for a 23-amino acid long peptide (HAfp1-23), whose larger activity than HAfp1-20 has been demonstrated recently. In this paper, we analyze the effect of N-terminal charge on peptide-mediated fusion efficiency and conformation changes at the membrane interface by comparison with the corresponding N-acetylated peptides of 20- and 23-amino acid lengths. We found that higher fusogenic activities of peptides with unmodified amino termini correlates with their ability to form helical hairpin structures oriented perpendicularly to the membrane plane. Molecular dynamics simulations showed that acetylated peptides adopt open and surface-bound conformation more often, which induced less disorder of the phospholipid chains, as compared to species with unmodified amino termini. PMID- 29443946 TI - A Comparative Study of Human Saposins. AB - Saposins are small proteins implicated in trafficking and loading of lipids onto Cluster of Differentiation 1 (CD1) receptor proteins that in turn present lipid antigens to T cells and a variety of T-cell receptors, thus playing a crucial role in innate and adaptive immune responses in humans. Despite their low sequence identity, the four types of human saposins share a similar folding pattern consisting of four helices linked by three conserved disulfide bridges. However, their lipid-binding abilities as well as their activities in extracting, transporting and loading onto CD1 molecules a variety of sphingo- and phospholipids in biological membranes display two striking characteristics: a strong pH-dependence and a structural change between a compact, closed conformation and an open conformation. In this work, we present a comparative computational study of structural, electrostatic, and dynamic features of human saposins based upon their available experimental structures. By means of structural alignments, surface analyses, calculation of pH-dependent protonation states, Poisson-Boltzmann electrostatic potentials, and molecular dynamics simulations at three pH values representative of biological media where saposins fulfill their function, our results shed light into their intrinsic features. The similarities and differences in this class of proteins depend on tiny variations of local structural details that allow saposins to be key players in triggering responses in the human immune system. PMID- 29443948 TI - Shared Housing Arrangements in Germany-An Equitable Alternative to Long Term Care Services beyond Homes and Institutions? AB - Given the saliency of socio-demographic pressures, the highly restrictive definition of "need for care" characterizing the German long-term care system at its foundations in 1994 has since been subject to various expansionary reforms. This has translated into greater interest in innovative care models that provide more choice and flexibility to beneficiaries. One such model is 'shared housing arrangements' ("ambulant betreute Wohngemeinschaften"), where a small group of people rent private rooms, while sharing a common space, domestic support, and nursing care. Using interview and secondary data, this study examines the potential for such arrangements to provide an equitable alternative to care that is accessible to a larger population of beneficiaries than presently seen in Germany. PMID- 29443947 TI - Vertebrate Genome Evolution in the Light of Fish Cytogenomics and rDNAomics. AB - To understand the cytogenomic evolution of vertebrates, we must first unravel the complex genomes of fishes, which were the first vertebrates to evolve and were ancestors to all other vertebrates. We must not forget the immense time span during which the fish genomes had to evolve. Fish cytogenomics is endowed with unique features which offer irreplaceable insights into the evolution of the vertebrate genome. Due to the general DNA base compositional homogeneity of fish genomes, fish cytogenomics is largely based on mapping DNA repeats that still represent serious obstacles in genome sequencing and assembling, even in model species. Localization of repeats on chromosomes of hundreds of fish species and populations originating from diversified environments have revealed the biological importance of this genomic fraction. Ribosomal genes (rDNA) belong to the most informative repeats and in fish, they are subject to a more relaxed regulation than in higher vertebrates. This can result in formation of a literal 'rDNAome' consisting of more than 20,000 copies with their high proportion employed in extra-coding functions. Because rDNA has high rates of transcription and recombination, it contributes to genome diversification and can form reproductive barrier. Our overall knowledge of fish cytogenomics grows rapidly by a continuously increasing number of fish genomes sequenced and by use of novel sequencing methods improving genome assembly. The recently revealed exceptional compositional heterogeneity in an ancient fish lineage (gars) sheds new light on the compositional genome evolution in vertebrates generally. We highlight the power of synergy of cytogenetics and genomics in fish cytogenomics, its potential to understand the complexity of genome evolution in vertebrates, which is also linked to clinical applications and the chromosomal backgrounds of speciation. We also summarize the current knowledge on fish cytogenomics and outline its main future avenues. PMID- 29443949 TI - Detection-Response Task-Uses and Limitations. AB - The Detection-Response Task is a method for assessing the attentional effects of cognitive load in a driving environment. Drivers are presented with a sensory stimulus every 3-5 s, and are asked to respond to it by pressing a button attached to their finger. Response times and hit rates are interpreted as indicators of the attentional effect of cognitive load. The stimuli can be visual, tactile and auditory, and are chosen based on the type of in-vehicle system or device that is being evaluated. Its biggest disadvantage is that the method itself also affects the driver's performance and secondary task completion times. Nevertheless, this is an easy to use and implement method, which allows relevant assessment and evaluation of in-vehicle systems. By following the recommendations and taking into account its limitations, researchers can obtain reliable and valuable results on the attentional effects of cognitive load on drivers.

AB - Literature regarding the use of home enteral nutrition (HEN) and how it is reimbursed in the Asia Pacific region is limited. This research survey aims to determine the availability of HEN, the type of feeds and enteral access used, national reimbursement policies, the presence of nutrition support teams (NSTs), and clinical nutrition education in this region. An electronic questionnaire was sent to 20 clinical nutrition societies and leaders in the Asia Pacific region in August 2017, where thirteen countries responded. Comparison of HEN reimbursement and practice between countries of different income groups based on the World Bank's data was investigated. Financial support for HEN is only available in 40% of the countries. An association was found between availability of financial support for HEN and health expenditure (r = 0.63, p = 0.021). High and middle upper income countries use mainly commercial supplements for HEN, while lower middle income countries use mainly blenderized diet. The presence of NSTs is limited, and only present mainly in acute settings. Sixty percent of the countries indicated an urgent need for funding and reimbursement of HEN. This survey demonstrates the varied clinical and economic situation in the Asia Pacific region. There is a lack of reimbursement, clinical support, and inadequate educational opportunities, especially for the lower-middle income countries. PMID- 29443952 TI - Microhydration and the Enhanced Acidity of Free Radicals. AB - Recent theoretical research employing a continuum solvent model predicted that radical centers would enhance the acidity (RED-shift) of certain proton-donor molecules. Microhydration studies employing a DFT method are reported here with the aim of establishing the effect of the solvent micro-structure on the acidity of radicals with and without RED-shifts. Microhydration cluster structures were obtained for carboxyl, carboxy-ethynyl, carboxy-methyl, and hydroperoxyl radicals. The numbers of water molecules needed to induce spontaneous ionization were determined. The hydration clusters formed primarily round the CO2 units of the carboxylate-containing radicals. Only 4 or 5 water molecules were needed to induce ionization of carboxyl and carboxy-ethynyl radicals, thus corroborating their large RED-shifts.

AB - The larvicidal activity of essential oils cinnamon (Cinnamomumverum J. Presl), Mexican lime (Citrusaurantifolia Swingle) cumin (Cuminumcyminum Linnaeus), clove (Syzygiumaromaticum (L.) Merr. & L.M.Perry), laurel (Laurusnobilis Linnaeus), Mexican oregano (Lippiaberlandieri Schauer) and anise (Pimpinellaanisum Linnaeus)) and their major components are tested against larvae and pupae of Culexquinquefasciatus Say. Third instar larvae and pupae are used for determination of lethality and mortality. Essential oils with more than 90% mortality after a 30-min treatment are evaluated at different time intervals. Of the essential oils tested, anise and Mexican oregano are effective against larvae, with a median lethal concentration (LC50) of 4.7 and 6.5 ug/mL, respectively. Anise essential oil and t-anethole are effective against pupae, with LC50 values of 102 and 48.7 ug/mL, respectively. Oregano essential oil and carvacrol also have relevant activities. A kinetic analysis of the larvicidal activity, the oviposition deterrent effect and assays of the effects of the binary mixtures of chemical components are undertaken. Results show that anethole has synergistic effects with other constituents. This same effect is observed for carvacrol and thymol. Limonene shows antagonistic effect with beta-pinene. The high larvicidal and pupaecidal activities of essential oils and its components demonstrate that they can be potential substitutes for chemical compounds used in mosquitoes control programs. PMID- 29443953 TI - A Comparison of Cats (Felis silvestris catus) Housed in Groups and Single Cages at a Shelter: A Retrospective Matched Cohort Study. AB - The merits of various housing options for domestic cats in shelters have been debated. However, comparisons are difficult to interpret because cats are typically not able to be randomly assigned to different housing conditions. In the current study, we attempted to address some of these issues by creating a retrospective matched cohort of cats in two housing types. Cats in group housing (GH) were matched with cats in single housing (SH) that were the same age, sex, breed, coat color, and size. Altogether we were able to find a match for 110 GH cats. We compared these two groups on several measures related to their experience at the shelter such as moves and the development of behavioral problems. We also compared these groups on outcomes including length of stay, live release, and returns after adoption. We found that while the frequency of moves was similar in both groups, SH cats were more likely to be moved to offsite facilities than GH cats. SH cats also spent a smaller proportion of time on the adoption floor. Length of stay and, live release and returns after adoption did not significantly differ across groups, however GH cats were two times as likely to be returned after adoption. Future research should look at the behavioral impacts of shelter decision-making regarding moving and management of cats in different housing systems.

AB - Biochar is an excellent absorbent for most heavy metal ions and organic pollutants with high specific surface area, strong aperture structure, high stability, higher cation exchange capacity and rich surface functional groups. To improve the selective adsorption capacity of biochar to designated heavy metal ions, biochar prepared by agricultural waste is modified via Ionic-Imprinted Technique. Fourier transform infrared (FT-IR) spectra analysis and X-ray photoelectron spectroscopy (XPS) analysis of imprinted biochar (IB) indicate that 3-Mercaptopropyltrimethoxysilane is grafted on biochar surface through Si-O-Si bonds. The results of adsorption experiments indicate that the suitable pH range is about 3.0-8.0, the dosage is 2.0 g.L-1, and the adsorption equilibrium is reached within 960 min. In addition, the data match pseudo-second-order kinetic model and Langmuir model well. The computation results of adsorption thermodynamics and stoichiometric displacement theory of adsorption (SDT-A) prove that the adsorption process is spontaneous and endothermic. Finally, IB possesses a higher selectivity adsorption to Cd(II) and a better reuse capacity. The functionalized biochar could solidify designated ions stably. PMID- 29443955 TI - Exploration and Exploitation of Novel SSR Markers for Candidate Transcription Factor Genes in Lilium Species. AB - Lilies (Lilium sp.) are commercially important horticultural crops widely cultivated for their flowers and bulbs. Here, we conducted large-scale data mining of the lily transcriptome to develop transcription factor (TF)-associated microsatellite markers (TFSSRs). Among 216,768 unigenes extracted from our sequence data, 6966 unigenes harbored simple sequence repeats (SSRs). Seventy-one SSRs were associated with TF genes, and these were used to design primers and validate their potential as markers. These 71 SSRs were accomplished with 31 transcription factor families; including bHLH, MYB, C2H2, ERF, C3H, NAC, bZIP, and so on. Fourteen highly polymorphic SSRs were selected based on Polymorphic Information Content (PIC) values and used to study genetic diversity and population structure in lily accessions. Higher genetic diversity was observed in Longiflorum compared to Oriental and Asiatic populations. Lily accessions were divided into three sub-populations based in our structure analysis, and an un rooted neighbor-joining tree effectively separated the accessions according to Asiatic, Oriental, and Longiflorum subgroups. Finally, we showed that 46 of the SSR-associated genes were differentially expressed in response to Botrytiselliptica infection. Thus, our newly developed TFSSR markers represent a powerful tool for large-scale genotyping, high-density and comparative mapping, marker-aided backcrossing, and molecular diversity analysis of Lilium sp.

AB - Gold and nickel bisdithiolene complexes with methyl and tert-butyl substituted thiophenetetrathiafulavalenedithiolate ligands (alpha-mtdt and alpha-tbtdt) were prepared and characterized. These complexes were obtained, under anaerobic conditions, as tetrabutylammonium salts. The diamagnetic gold monoanion (n Bu4N)[Au(alpha-mtdt)2] (3) and nickel dianionic species (n-Bu4N)x[Ni(alpha mtdt)2] (x = 1,2) (4) were similar to the related non-substituted extended thiophenic-TTF (TTF = tetrathiafulvalene) bisdithiolenes. However the introduction of the large, bulky substituent tert-butyl, led to the formation of a Au (I) dinuclear complex, (n-Bu4N)2[Au2(alpha-tbtdt)2] (5). The neutral methyl substituted gold and nickel complexes were easily obtained through air or iodine exposure as polycrystalline or amorphous fine powder. [Au(alpha-mtdt)2] (6) and [Ni(alpha-mtdt)2] (7) polycrystalline samples display properties of a metallic system with a room temperature electrical conductivity of 0.32 S/cm and ~4 S/cm and a thermoelectric power of ~5 uV/K and ~32 uV/K, respectively. While [Au(alpha mtdt)2] (6) presented a Pauli-like magnetic susceptibility typical of conducting systems, in [Ni(alpha-mtdt)2] (7) large magnetic susceptibilities indicative of high spin states were observed. Both electric transport properties and magnetic properties for gold and nickel [M(alpha-mtdt)2] are indicative that these compounds are single component molecular conductors.

AB - BACKGROUND This study aimed to explore the feasibility and efficacy of bone cement-augmented short-segmental pedicle screw fixation in treating Kummell disease. MATERIAL AND METHODS From June 2012 to June 2015, 18 patients with Kummell disease with spinal canal stenosis were enrolled in this study. Each patient was treated with bone cement-augmented short-segment fixation and posterolateral bone grafting, and posterior decompression was performed when needed. All patients were followed up for 12-36 months. We retrospectively reviewed outcomes, including the Oswestry disability index (ODI), visual analog scale (VAS) score, anterior and posterior heights of fractured vertebrae, kyphotic Cobb angle, and neurological function by Frankel classification. RESULTS The VAS grades, ODI scores, anterior heights of affected vertebrae, and kyphotic Cobb angles showed statistically significant differences between pre- and postoperative and between preoperative and final follow-up values (P<0.05), whereas the differences between postoperative and final follow-up values were not statistically significant (P>0.05). The differences between posterior vertebral heights at each time point were not statistically significant (P>0.05). Improved neurological function was observed in 12 cases at final follow-up. Three cases had complications, including asymptomatic cement leakage in 2 patients and delayed wound infection in 1 patient. CONCLUSIONS Bone cement-augmented short segment pedicle screw fixation is safe and effective for treating Kummell disease, and can achieve satisfactory correction of kyphosis and vertebral height, with pain relief and improvement in neurological function, with few complications. PMID- 29443958 TI - Tissue stiffening coordinates morphogenesis by triggering collective cell migration in vivo. AB - Collective cell migration is essential for morphogenesis, tissue remodelling and cancer invasion. In vivo, groups of cells move in an orchestrated way through tissues. This movement involves mechanical as well as molecular interactions between cells and their environment. While the role of molecular signals in collective cell migration is comparatively well understood, how tissue mechanics influence collective cell migration in vivo remains unknown. Here we investigated the importance of mechanical cues in the collective migration of the Xenopus laevis neural crest cells, an embryonic cell population whose migratory behaviour has been likened to cancer invasion. We found that, during morphogenesis, the head mesoderm underlying the cephalic neural crest stiffens. This stiffening initiates an epithelial-to-mesenchymal transition in neural crest cells and triggers their collective migration. To detect changes in their mechanical environment, neural crest cells use mechanosensation mediated by the integrin vinculin-talin complex. By performing mechanical and molecular manipulations, we show that mesoderm stiffening is necessary and sufficient to trigger neural crest migration. Finally, we demonstrate that convergent extension of the mesoderm, which starts during gastrulation, leads to increased mesoderm stiffness by increasing the cell density underneath the neural crest. These results show that convergent extension of the mesoderm has a role as a mechanical coordinator of morphogenesis, and reveal a link between two apparently unconnected processes gastrulation and neural crest migration-via changes in tissue mechanics. Overall, we demonstrate that changes in substrate stiffness can trigger collective cell migration by promoting epithelial-to-mesenchymal transition in vivo. More broadly, our results raise the idea that tissue mechanics combines with molecular effectors to coordinate morphogenesis. PMID- 29443959 TI - Transcriptional regulation by NR5A2 links differentiation and inflammation in the pancreas. AB - Chronic inflammation increases the risk of developing one of several types of cancer. Inflammatory responses are currently thought to be controlled by mechanisms that rely on transcriptional networks that are distinct from those involved in cell differentiation. The orphan nuclear receptor NR5A2 participates in a wide variety of processes, including cholesterol and glucose metabolism in the liver, resolution of endoplasmic reticulum stress, intestinal glucocorticoid production, pancreatic development and acinar differentiation. In genome-wide association studies, single nucleotide polymorphisms in the vicinity of NR5A2 have previously been associated with the risk of pancreatic adenocarcinoma. In mice, Nr5a2 heterozygosity sensitizes the pancreas to damage, impairs regeneration and cooperates with mutant Kras in tumour progression. Here, using a global transcriptomic analysis, we describe an epithelial-cell-autonomous basal pre-inflammatory state in the pancreas of Nr5a2+/- mice that is reminiscent of the early stages of pancreatitis-induced inflammation and is conserved in histologically normal human pancreases with reduced expression of NR5A2 mRNA. In Nr5a2+/-mice, NR5A2 undergoes a marked transcriptional switch, relocating from differentiation-specific to inflammatory genes and thereby promoting gene transcription that is dependent on the AP-1 transcription factor. Pancreatic deletion of Jun rescues the pre-inflammatory phenotype, as well as binding of NR5A2 to inflammatory gene promoters and the defective regenerative response to damage. These findings support the notion that, in the pancreas, the transcriptional networks involved in differentiation-specific functions also suppress inflammatory programmes. Under conditions of genetic or environmental constraint, these networks can be subverted to foster inflammation. PMID- 29443961 TI - A coherent spin-photon interface in silicon. AB - Electron spins in silicon quantum dots are attractive systems for quantum computing owing to their long coherence times and the promise of rapid scaling of the number of dots in a system using semiconductor fabrication techniques. Although nearest-neighbour exchange coupling of two spins has been demonstrated, the interaction of spins via microwave-frequency photons could enable long distance spin-spin coupling and connections between arbitrary pairs of qubits ('all-to-all' connectivity) in a spin-based quantum processor. Realizing coherent spin-photon coupling is challenging because of the small magnetic-dipole moment of a single spin, which limits magnetic-dipole coupling rates to less than 1 kilohertz. Here we demonstrate strong coupling between a single spin in silicon and a single microwave-frequency photon, with spin-photon coupling rates of more than 10 megahertz. The mechanism that enables the coherent spin-photon interactions is based on spin-charge hybridization in the presence of a magnetic field gradient. In addition to spin-photon coupling, we demonstrate coherent control and dispersive readout of a single spin. These results open up a direct path to entangling single spins using microwave-frequency photons. PMID- 29443960 TI - TGFbeta attenuates tumour response to PD-L1 blockade by contributing to exclusion of T cells. AB - Therapeutic antibodies that block the programmed death-1 (PD-1)-programmed death ligand 1 (PD-L1) pathway can induce robust and durable responses in patients with various cancers, including metastatic urothelial cancer. However, these responses only occur in a subset of patients. Elucidating the determinants of response and resistance is key to improving outcomes and developing new treatment strategies. Here we examined tumours from a large cohort of patients with metastatic urothelial cancer who were treated with an anti-PD-L1 agent (atezolizumab) and identified major determinants of clinical outcome. Response to treatment was associated with CD8+ T-effector cell phenotype and, to an even greater extent, high neoantigen or tumour mutation burden. Lack of response was associated with a signature of transforming growth factor beta (TGFbeta) signalling in fibroblasts. This occurred particularly in patients with tumours, which showed exclusion of CD8+ T cells from the tumour parenchyma that were instead found in the fibroblast and collagen-rich peritumoural stroma; a common phenotype among patients with metastatic urothelial cancer. Using a mouse model that recapitulates this immune excluded phenotype, we found that therapeutic co-administration of TGFbeta blocking and anti-PD-L1 antibodies reduced TGFbeta signalling in stromal cells, facilitated T-cell penetration into the centre of tumours, and provoked vigorous anti-tumour immunity and tumour regression. Integration of these three independent biological features provides the best basis for understanding patient outcome in this setting and suggests that TGFbeta shapes the tumour microenvironment to restrain anti-tumour immunity by restricting T-cell infiltration.

PMID- 29443962 TI - A programmable two-qubit quantum processor in silicon. AB - Now that it is possible to achieve measurement and control fidelities for individual quantum bits (qubits) above the threshold for fault tolerance, attention is moving towards the difficult task of scaling up the number of physical qubits to the large numbers that are needed for fault-tolerant quantum computing. In this context, quantum-dot-based spin qubits could have substantial advantages over other types of qubit owing to their potential for all-electrical operation and ability to be integrated at high density onto an industrial platform. Initialization, readout and single- and two-qubit gates have been demonstrated in various quantum-dot-based qubit representations. However, as seen with small-scale demonstrations of quantum computers using other types of qubit, combining these elements leads to challenges related to qubit crosstalk, state leakage, calibration and control hardware. Here we overcome these challenges by using carefully designed control techniques to demonstrate a programmable two qubit quantum processor in a silicon device that can perform the Deutsch-Josza algorithm and the Grover search algorithm-canonical examples of quantum algorithms that outperform their classical analogues. We characterize the entanglement in our processor by using quantum-state tomography of Bell states, measuring state fidelities of 85-89 per cent and concurrences of 73-82 per cent. These results pave the way for larger-scale quantum computers that use spins confined to quantum dots. PMID- 29443966 TI - Global patterns of tropical forest fragmentation. AB - Remote sensing enables the quantification of tropical deforestation with high spatial resolution. This in-depth mapping has led to substantial advances in the analysis of continent-wide fragmentation of tropical forests. Here we identified approximately 130 million forest fragments in three continents that show surprisingly similar power-law size and perimeter distributions as well as fractal dimensions. Power-law distributions have been observed in many natural phenomena such as wildfires, landslides and earthquakes. The principles of percolation theory provide one explanation for the observed patterns, and suggest that forest fragmentation is close to the critical point of percolation; simulation modelling also supports this hypothesis. The observed patterns emerge not only from random deforestation, which can be described by percolation theory, but also from a wide range of deforestation and forest-recovery regimes. Our models predict that additional forest loss will result in a large increase in the total number of forest fragments-at maximum by a factor of 33 over 50 years-as well as a decrease in their size, and that these consequences could be partly mitigated by reforestation and forest protection.

AB - Cerebrovascular disease is the third most common cause of death in developed countries, but our understanding of the cells that compose the cerebral vasculature is limited. Here, using vascular single-cell transcriptomics, we provide molecular definitions for the principal types of blood vascular and vessel-associated cells in the adult mouse brain. We uncover the transcriptional basis of the gradual phenotypic change (zonation) along the arteriovenous axis and reveal unexpected cell type differences: a seamless continuum for endothelial cells versus a punctuated continuum for mural cells. We also provide insight into pericyte organotypicity and define a population of perivascular fibroblast-like cells that are present on all vessel types except capillaries. Our work illustrates the power of single-cell transcriptomics to decode the higher organizational principles of a tissue and may provide the initial chapter in a molecular encyclopaedia of the mammalian vasculature.

PMID- 29443964 TI - TGFbeta drives immune evasion in genetically reconstituted colon cancer metastasis. AB - Most patients with colorectal cancer die as a result of the disease spreading to other organs. However, no prevalent mutations have been associated with metastatic colorectal cancers. Instead, particular features of the tumour microenvironment, such as lack of T-cell infiltration, low type 1 T-helper cell (TH1) activity and reduced immune cytotoxicity or increased TGFbeta levels predict adverse outcomes in patients with colorectal cancer. Here we analyse the interplay between genetic alterations and the tumour microenvironment by crossing mice bearing conditional alleles of four main colorectal cancer mutations in intestinal stem cells. Quadruple-mutant mice developed metastatic intestinal tumours that display key hallmarks of human microsatellite-stable colorectal cancers, including low mutational burden, T-cell exclusion and TGFbeta-activated stroma. Inhibition of the PD-1-PD-L1 immune checkpoint provoked a limited response in this model system. By contrast, inhibition of TGFbeta unleashed a potent and enduring cytotoxic T-cell response against tumour cells that prevented metastasis. In mice with progressive liver metastatic disease, blockade of TGFbeta signalling rendered tumours susceptible to anti-PD-1-PD-L1 therapy. Our data show that increased TGFbeta in the tumour microenvironment represents a primary mechanism of immune evasion that promotes T-cell exclusion and blocks acquisition of the TH1-effector phenotype. Immunotherapies directed against TGFbeta signalling may therefore have broad applications in treating patients with advanced colorectal cancer. PMID- 29443967 TI - Peptidoglycan synthesis drives an FtsZ-treadmilling-independent step of cytokinesis. AB - Peptidoglycan is the main component of the bacterial wall and protects cells from the mechanical stress that results from high intracellular turgor. Peptidoglycan biosynthesis is very similar in all bacteria; bacterial shapes are therefore mainly determined by the spatial and temporal regulation of peptidoglycan synthesis rather than by the chemical composition of peptidoglycan. The form of rod-shaped bacteria, such as Bacillus subtilis or Escherichia coli, is generated by the action of two peptidoglycan synthesis machineries that act at the septum and at the lateral wall in processes coordinated by the cytoskeletal proteins FtsZ and MreB, respectively. The tubulin homologue FtsZ is the first protein recruited to the division site, where it assembles in filaments-forming the Z ring-that undergo treadmilling and recruit later divisome proteins. The rate of treadmilling in B. subtilis controls the rates of both peptidoglycan synthesis and cell division. The actin homologue MreB forms discrete patches that move circumferentially around the cell in tracks perpendicular to the long axis of the cell, and organize the insertion of new cell wall during elongation. Cocci such as Staphylococcus aureus possess only one type of peptidoglycan synthesis machinery, which is diverted from the cell periphery to the septum in preparation for division. The molecular cue that coordinates this transition has remained elusive. Here we investigate the localization of S. aureus peptidoglycan biosynthesis proteins and show that the recruitment of the putative lipid II flippase MurJ to the septum, by the DivIB-DivIC-FtsL complex, drives peptidoglycan incorporation to the midcell. MurJ recruitment corresponds to a turning point in cytokinesis, which is slow and dependent on FtsZ treadmilling before MurJ arrival but becomes faster and independent of FtsZ treadmilling after peptidoglycan synthesis activity is directed to the septum, where it provides additional force for cell envelope constriction.

AB - Methylation of nucleotides in ribosomal RNAs (rRNAs) is a ubiquitous feature that occurs in all living organisms. Identification of all enzymes responsible for rRNA methylation, as well as mapping of all modified rRNA residues, is now complete for a number of model species, such as Escherichia coli and Saccharomyces cerevisiae. Recent high-resolution structures of bacterial ribosomes provided the first direct visualization of methylated nucleotides. The structures of ribosomes from various organisms and organelles have also lately become available, enabling comparative structure-based analysis of rRNA methylation sites in various taxonomic groups. In addition to the conserved core of modified residues in ribosomes from the majority of studied organisms, structural analysis points to the functional roles of some of the rRNA methylations, which are discussed in this Review in an evolutionary context.

AB - Non-enzymatic post-translational modifications of proteins can occur when a nucleophilic or redox-sensitive amino acid side chain encounters a reactive metabolite. In many cases, the biological function of these modifications is limited by their irreversibility, and consequently these non-enzymatic modifications are often considered as indicators of stress and disease. Certain non-enzymatic post-translational modifications, however, can be reversed, which provides an additional layer of regulation and renders these modifications suitable for controlling a diverse set of cellular processes ranging from signaling to metabolism. Here we summarize recent examples of irreversible and reversible non-enzymatic modifications, with an emphasis on the latter category. We use two examples, lysine glutarylation and pyrophosphorylation, to highlight principles of the regulation of reversible non-enzymatic post-translational modifications in more detail. Overall, a picture emerges that goes well beyond nonspecific chemical reactions and cellular damage, and instead portrays multifaceted functions of non-enzymatic post-translational modifications.

PMID- 29443978 TI - Distinguishing RNA modifications from noise in epitranscriptome maps. AB - Messenger RNA (mRNA) and long noncoding RNA (lncRNA) can be subjected to a variety of post-transcriptional modifications that markedly influence their fate and function. This concept of 'epitranscriptomic' modifications and the understanding of their function has been driven by new technologies for transcriptome-wide mapping of modified nucleotides using next-generation sequencing. Mapping technologies have successfully documented the location and prevalence of several modified nucleotides in the transcriptome. However, some mapping methods have led to proposals of pervasive novel RNA modifications that have subsequently been shown to be exceptionally rare. These controversies have resulted in confusion about the identity of the modified nucleotides comprising the epitranscriptome in mRNA and lncRNA. Here we discuss the different transcriptome-wide technologies for mapping modified nucleotides. We describe why these methods can have poor accuracy and specificity. Finally, we describe emerging strategies that minimize false positives and other pitfalls associated with mapping and measuring epitranscriptomic modifications.

AB - Despite decades of accumulated knowledge about proteins and their post translational modifications (PTMs), numerous questions remain regarding their molecular composition and biological function. One of the most fundamental queries is the extent to which the combinations of DNA-, RNA- and PTM-level variations explode the complexity of the human proteome. Here, we outline what we know from current databases and measurement strategies including mass spectrometry-based proteomics. In doing so, we examine prevailing notions about the number of modifications displayed on human proteins and how they combine to generate the protein diversity underlying health and disease. We frame central issues regarding determination of protein-level variation and PTMs, including some paradoxes present in the field today. We use this framework to assess existing data and to ask the question, "How many distinct primary structures of proteins (proteoforms) are created from the 20,300 human genes?" We also explore prospects for improving measurements to better regularize protein-level biology and efficiently associate PTMs to function and phenotype.

AB - A thermal ghost imaging scheme between two distant parties is proposed and experimentally demonstrated over long-distance optical fibers. In the scheme, the weak thermal light is split into two paths. Photons in one path are spatially diffused according to their frequencies by a spatial dispersion component, then illuminate the object and record its spatial transmission information. Photons in the other path are temporally diffused by a temporal dispersion component. By the coincidence measurement between photons of two paths, the object can be imaged in a way of ghost imaging, based on the frequency correlation between photons in the two paths. In the experiment, the weak thermal light source is prepared by the spontaneous four-wave mixing in a silicon waveguide. The temporal dispersion is introduced by single-mode fibers of 50 km, which also could be looked at as a fiber link. Experimental results show that this scheme can be realized over long distance optical fibers. PMID- 29443988 TI - Quantitative imaging of anisotropic material properties with vectorial ptychography.

PMID- 29443986 TI - Insights into the biogenesis, function, and regulation of ADP-ribosylation. AB - ADP-ribosylation-the transfer of ADP-ribose (ADPr) from NAD+ onto target molecules-is catalyzed by members of the ADP-ribosyltransferase (ART) superfamily of proteins, found in all kingdoms of life. Modification of amino acids in protein targets by ADPr regulates critical cellular pathways in eukaryotes and underlies the pathogenicity of certain bacteria. Several members of the ART superfamily are highly relevant for disease; these include the poly(ADP-ribose) polymerases (PARPs), recently shown to be important cancer targets, and the bacterial toxins diphtheria toxin and cholera toxin, long known to be responsible for the symptoms of diphtheria and cholera that result in morbidity. In this Review, we discuss the functions of amino acid ADPr modifications and the ART proteins that make them, the nature of the chemical linkage between ADPr and its targets and how this impacts function and stability, and the way that ARTs select specific amino acids in targets to modify.

AB - We propose a Maxwellian near-to-eye display implemented using a multiplexed holographic optical element. Maxwellian configuration removes the focal cue of the displayed virtual image completely, presenting an always-focused image to the observer regardless of the focal length of the eye. The transparent property of the holographic optical element enables the optical see-through feature, making the proposed near-to-eye display suitable for augmented reality applications. The multiplexing of multiple concave mirrors into a single holographic optical element enlarges the effective eyebox, relaxing the limitation of the conventional Maxwellian displays. Optical experiment confirms that the proposed display can present always-focused images on top of the real environment with 9.2 degrees (H)*5.2 degrees (V) field of view, and 9 mm (H)*3 mm (V) eyebox.

AB - It is well known that electromagnetic radiation propagates along a straight line, but this common sense was broken by the artificial curved light-the Airy beam. In this Letter, we demonstrate a new type of curved light beam besides the Airy beam, the so-called "photonic hook." This photonic hook is a curved high intensity focus by a dielectric trapezoid particle illuminated by a plane wave. The difference between the phase velocity and the interference of the waves inside the particle causes the phenomenon of focus bending.

AB - Ultrasound detection is performed by measuring laser reflection off a surface plasmon resonance cavity which is integrated at a single-mode fiber end facet. It shows a total noise (or laser RIN) equivalent pressure of 9.7 KPa (or 5.2 KPa) over 0-20 MHz, a 6-dB angular detection range as large as 70 degrees near 10 MHz, a detection bandwidth larger than 125 MHz, and a stable performance for over 20 min without feedback in ambient conditions. Its small form factor, fiber-optic integration, almost omnidirectional responsivity and large bandwidth are favorable for in vivo applications and high resolution imaging. PMID- 29443992 TI - Spectral asymmetries in the resonance fluorescence of two-level systems under pulsed excitation. AB - We present an open-system master equation study of the coherent and incoherent resonance fluorescence spectrum from a two-level quantum system under coherent pulsed excitation. Several pronounced features that differ from the fluorescence under a constant drive are highlighted, including a multi-peak structure and a pronounced off-resonant spectral asymmetry, in stark contrast to the conventional symmetrical Mollow triplet. We also study semiconductor quantum dot systems using a polaron master equation and show how the key features of dynamic resonance fluorescence change with electron-acoustic-phonon coupling. PMID- 29443993 TI - Terahertz-based retrieval of the spectral phase and amplitude of ultrashort laser pulses. AB - Terahertz (THz) radiation is of great interest for a variety of applications, e.g., particle accelerations, spectroscopy investigations of quantum systems, and high-field study of materials. One of the most common laser-based processes to produce THz pulses is optical rectification, which transduces an infrared pump laser to the THz domain (0.1-20 THz). In this work, we propose and theoretically describe a method to characterize the amplitude and phase of the electric field of the pump laser pulse relying on THz generation and detection. We demonstrate with a numerical example how THz radiation can be used as diagnostics to characterize laser pulses with temporal length at the femtosecond level. PMID- 29443994 TI - Adaptive pumping for spectral control of broadband second-harmonic generation. AB - Second-harmonic generation (SHG) is always a significant frequency conversion process in nonlinear optics for many great applications but can be limited when broadband spectral laser sources are involved, e.g., femtosecond pulses. The conversion efficiency can be high, but the spectral control is hard because of the phase-matching (PM) limitation. Recently, a random quasi-phase-matching (QPM) scheme was proposed to make use of highly nonlinear materials that are difficult to be phase matched under traditional configurations. The spectral control is even harder in anisotropic random materials, and the coherence is completely lost. Here, we proposed an approach to solve this problem by coherent light control via feedback-based wavefront shaping. We utilized this method for spectral control of broadband SHG, which can be efficient even in strongly scattering media. Randomly selected wavelengths in the broadband spectra were enhanced with a good selectivity, and the direction was also controlled in a three-dimensional (3D) configuration. This technique paves the way for convenient spatial and spectral control of both linear and nonlinear emissions and a local enhancement of their conversion efficiency, indicating great progress in both random and ultrafast nonlinear optics.

AB - This Letter demonstrates a refractometer in integrated optical fiber, a new optical platform that planarizes fiber using flame hydrolysis deposition (FHD). The unique advantage of the technology is survivability in harsh environments. The platform is mechanically robust, and can survive elevated temperatures approaching 1000 degrees C and exposure to common solvents, including acetone, gasoline, and methanol. For the demonstrated refractometer, fabrication was achieved through wet etching an SMF-28 fiber to a diameter of 8 MUm before FHD planarization. An external refractive index was monitored using fiber Bragg gratings (FBGs), written into the core of the planarized fiber. A direct comparison to alternative FBG refractometers is made, for which the developed platform is shown to have comparable sensitivity, with the added advantage of survivability in harsh environments. PMID- 29443996 TI - Suspended silicon waveguides for long-wave infrared wavelengths. AB - In this Letter, we report suspended silicon waveguides operating at a wavelength of 7.67 MUm with a propagation loss of 3.1+/-0.3 dB/cm. To our knowledge, this is the first demonstration of low-loss silicon waveguides at such a long wavelength, with loss comparable to other platforms that use more exotic materials. The suspended Si waveguide core is supported by a sub-wavelength grating that provides lateral optical confinement while also allowing access to the buried oxide layer so that it can be wet etched using hydrofluoric acid. We also demonstrate low-loss waveguide bends and s-bends. PMID- 29443997 TI - Ultra-low-threshold InGaN/GaN quantum dot micro-ring lasers. AB - In this work, we demonstrate ultra-low-threshold, optically pumped, room temperature lasing in GaN microdisk and micro-ring cavities containing InGaN quantum dots and fragmented quantum wells, with the lowest measured threshold at a record low of 6.2 MUJ/cm2. When pump volume decreases, we observe a systematic decrease in the lasing threshold of micro-rings. The photon loss rate, gamma, increases with increasing inner ring diameter, leading to a systematic decrease in the post-threshold slope efficiency, while the quality factor of the lasing mode remains largely unchanged. A careful analysis using finite-difference time domain simulations attributes the increased gamma to the loss of photons from lower-quality higher-order modes during amplified spontaneous emission. PMID- 29443998 TI - Phase conjugate digital inline holography (PCDIH). AB - Digital inline holography (DIH) provides instantaneous three-dimensional (3D) measurements of diffracting objects; however, phase disturbances in the beam path can distort the imaging. In this Letter, a phase conjugate digital inline holography (PCDIH) configuration is proposed for removal of phase disturbances. Brillouin-enhanced four-wave mixing produces a phase conjugate signal that back propagates along the DIH beam path. The results demonstrate the removal of distortions caused by gas-phase shocks to recover 3D images of diffracting objects. PMID- 29443999 TI - Absolute distance measurement by multi-heterodyne interferometry using an electro optic triple comb. AB - We experimentally demonstrate a method for absolute distance measurement using a triple-comb-based multi-heterodyne interferometer which has the capacity to simultaneously balance the non-ambiguous range, resolution, update rate, and cost. Three flat-top electro-optic combs generated via cascaded intensity and phase modulators are adopted to form a measurement scheme including rough and fine measurements, and the unknown distance is determined by detecting the phase changes of the consecutive synthetic wavelengths. Experimental results demonstrate an agreement within 750 nm over 80 m distance at an update rate of 167 MUs. PMID- 29444000 TI - Reducing Rowland ghosts in diffraction gratings by dynamic exposure near-field holography. AB - Near-field holography (NFH) combined with electron beam lithography (EBL)-written phase masks is a promising method for the rapid realization of diffraction gratings with high resolution and high accuracy in line density distribution. We demonstrate a dynamic exposure method in which the grating substrate is shifted during pattern transfer. This reduces the effects of stitching errors, resulting in the decreased intensity of the optical stray light (i.e., Rowland ghosts). We demonstrate the intensity suppression of ghosts by 60%. This illustrates the potential for dynamic NFH to suppress undesirable periodic patterns from phase masks and alleviate the stitching errors induced by EBL. PMID- 29444001 TI - Effective suppression of residual coherent phase error in a dual-polarization fiber optic gyroscope. AB - The impact of residual coherent phase error in a dual-polarization interferometric fiber optic gyroscope (IFOG) is investigated. Although it has been intuitively assumed that the coherence of a light source can be eliminated by a sufficient long fiber delay, the experiment and theory indicate that it still contributes a remarkable portion to long-term instability. After the residual coherent phase error is well handled, we demonstrate a dual-polarization IFOG with bias instability of 3.56*10-4 degrees /h. Comparisons show that such performance is even better than the conventional "minimal scheme" that operates on one polarization. PMID- 29444002 TI - Analytical model of waveform-controlled single-cycle light pulses from an undulator. AB - This Letter builds upon a recent concept [Phys. Rev. Lett.113, 104801 (2014)PRLTAO0031-900710.1103/PhysRevLett.113.104801] for producing ultrashort optical pulses through the coherent radiation of electrons in an undulator. Each pulse contains only a single oscillation cycle, and has a controlled waveform (and hence a stable carrier-envelope phase). While the concept had been demonstrated numerically, this Letter provides an analytical model for the radiation mechanism, thereby revealing three key observations: (i) the correlation between the waveforms of the optical and undulator fields; (ii) the free-space dispersion of transversely confined light; and (iii) the dependence of the optical pulse shape on the undulator field strength. PMID- 29444003 TI - Measurement of the topological charge and index of vortex vector optical fields with a space-variant half-wave plate. AB - Vortex vector optical fields (VVOFs) refer to a kind of vector optical field with an azimuth-variant polarization and a helical phase, simultaneously. Such a VVOF is defined by the topological index of the polarization singularity and the topological charge of the phase vortex. We present a simple method to measure the topological charge and index of VVOFs by using a space-variant half-wave plate (SV-HWP). The geometric phase grating of the SV-HWP diffracts a VVOF into +/-1 orders with orthogonally left- and right-handed circular polarizations. By inserting a polarizer behind the SV-HWP, the two circular polarization states project into the linear polarization and then interfere with each other to form the interference pattern, which enables the direct measurement of the topological charge and index of VVOFs. PMID- 29444004 TI - Demonstration of a thermo-optic phase shifter by utilizing high-Q resonance in high-index-contrast grating. AB - A thermo-optic phase shifter is proposed and demonstrated by utilizing the high-Q resonance in high-index-contrast grating (HCG). The Q-factor up to ~12000 is measured in a footprint of 110 MUm*300 MUm. By heating the HCG with paired metal strip micro-heaters, the optical resonance shifts, which induces phase modulation. A phase shift of ~1.2pi under heating power of ~32 mW is directly observed and demodulated from the fringes shifting in a Michelson interferometer. The proposed configuration can also be extended to realize high-speed phase shift by adopting electro-optical modulation. PMID- 29444005 TI - Single-pulse writing of a concave microlens array. AB - This work developed a method of femtosecond laser (fs-laser) parallel processing assisted by wet etching to fabricate 3D micro-optical components. A 2D fs-laser spot array with designed spatial distribution was generated by a spatial light modulator. A single-pulse exposure of the entire array was used for parallel processing. By subsequent wet etching, a close-packed hexagonal arrangement, 3D concave microlens array on a curved surface with a radius of approximately 120 MUm was fabricated, each unit lens of which has designable spatial distribution. Characterization of imaging was carried out by a microscope and showed a unique imaging property in multi-planes. This method provides a parallel and efficient technique to fabricate 3D micro-optical devices for applications in optofluidics, optical communication, and integrated optics. PMID- 29444006 TI - Highly uniform and monodisperse beta-NaYF4 : Sm3+ nanoparticles for a nanoscale optical thermometer. AB - Monodisperse beta-NaYF4:1%Sm3+ nanoparticles were fabricated successfully via the thermal decomposition technique. Strong temperature dependence of the Sm3+ emission was observed when its thermally populated state H7/26 was directly excited to the G5/24 level. This strategy not only can eliminate laser heating and background Stokes-type scattering noise but also has a high quantum yield as a result of one-photon excitation process. Under 594.0 nm laser excitation, the emission intensity of G5/24-H5/26 enhances monotonously with rising temperature from 300 K to 430 K, including a physiological temperature range (27 degrees C-60 degrees C). The relative temperature sensitivity can reach 1.1% K-1 and 0.91% K-1 at 300 K and 330 K, respectively. In addition, the repeatability of temperature sensing was evaluated under several heating-cooling cycles, and the decay curves of the emission at 560.0 nm (G5/24-H5/26) at different temperatures were also investigated. These results raise the prospects of monodisperse beta NaYF4:1%Sm3+ nanoparticles for optical temperature sensing in biomedicine fields. PMID- 29444007 TI - Three-dimensional inverse synthetic aperture lidar imaging for long-range spinning targets. AB - We present a three-dimensional (3D) imaging method for long-range spinning targets. This method acquires multi-angle two-dimensional (2D) images of spinning targets by the inverse synthetic aperture lidar (ISAL) imaging technique. The 3D distribution of the scattering coefficients of a target has a mapping relationship with the series of 2D images. This mapping is analyzed, and a 3D Hough transform is used to implement inverse mapping. The parameter space of the Hough transform is the estimation of the 3D distribution of the scattering coefficients. The 3D point spread function obtained by the method has narrow main lobe widths and sufficiently low side lobes to achieve high image quality, which is verified by computer simulations. In the simulations, the main lobe widths in the three dimensions are 0.29 cm, 0.29 cm, and 3.48 cm, respectively. In outdoor experiments, 3D images of targets at 1 km away from the lidar were obtained. The images clearly show the 3D shape of targets. PMID- 29444008 TI - Sensitive measurement of stress birefringence of fused silica substrates with cavity ring-down technique. AB - A polarized cavity ring-down technique was employed to precisely measure the residual stress birefringence of fused silica substrates with greatly enhanced measurement sensitivity. Intracavity birefringence resulted in beating of two orthogonally resonant modes in a Fabry-Perot cavity. The beating frequency of the ring-down decay was directly related to phase retardation induced by stress birefringence of optical components inside the cavity. For fused silica substrates, measurement reproducibilities of phase retardation of 2.38*10-6 rad and of optical path difference of 2.4*10-4 nm were experimentally achieved. In addition, spatially resolved mapping of stress birefringence of a fused silica substrate was obtained, which was in good agreement with that measured with a commercial stress birefringence measurement instrument. The experimental results demonstrated that cavity ring-down is a sensitive technique for stress birefringence measurements of optical components. PMID- 29444009 TI - Ultralow-threshold continuous-wave lasing assisted by a metallic optofluidic cavity exploiting continuous pump. AB - We report an ultralow-threshold continuous-wave lasing via a metallic optofluidic resonant cavity based on the symmetrical metal-cladding waveguide. The high quality factor Q and spontaneous emission coupling factor beta of the waveguide strengthen the interaction between the gain medium and the ultrahigh order modes (UOMs); hence, the room-temperature, narrowband lasing can be effectively pumped by a continuous laser of low intensity. Rhodamine 6G and methylene blue are chosen to verify the applicability of the proposed concept. Lasing is emitted from the chip surface when the pumped laser is well coupled into the UOMs. For methylene blue with a concentration of 2.57*10-13 mol/ml, the operated emission can be observed with the launched pump threshold as low as 2.1 MUW/cm2. PMID- 29444010 TI - 3-bit writing of information in nanoporous glass by a single sub-microsecond burst of femtosecond pulses. AB - We have found that a single sub-microsecond burst of femtosecond laser pulses produces a sub-micrometer cavity possessing the homogeneous birefringence with slow-axis orientation perpendicular to polarization of the laser beam in high silicate nanoporous glass. Retardance and the root mean square of slow-axis orientation are investigated in dependence on the energy and the number of pulses in the burst. A burst of just three pulses with 98 ns inter-pulse intervals has been shown to induce homogeneous birefringence, and a burst of four pulses has provided birefringence with retardance of 35 nm, which is sufficient for reliable readout of the information recorded with multilevel encoding in slow-axis orientation. A text file has been recorded and read out in an array of birefringent cavities, each carrying 3 bits of information. The sub-microsecond burst of femtosecond pulses paves the way for a multiple increase of the rate of digital information recording with multilevel encoding in glass.

AB - We demonstrate on-chip generation of correlated pairs of photons in the near visible spectrum using a CMOS compatible plasma-enhanced chemical vapor deposition silicon nitride photonic device. Photons are generated via spontaneous four wave mixing enhanced by a ring resonator with high intrinsic quality Q factor of 3,20,000, resulting in a generation rate of 950,000 pairsmW. The high brightness of this source offers the opportunity to expand photonic quantum technologies over a broad wavelength range and provides a path to develop fully integrated quantum chips working at room temperature. PMID- 29444012 TI - Engineering spectrally unentangled photon pairs from nonlinear microring resonators by pump manipulation. AB - The future of integrated quantum photonics relies heavily on the ability to engineer refined methods for preparing the quantum states needed to implement various quantum protocols. An important example of such states is quantum correlated photon pairs, which can be efficiently generated using spontaneous nonlinear processes in integrated microring-resonator structures. In this work, we propose a method for generating spectrally unentangled photon pairs from a standard microring resonator. The method utilizes interference between a primary and a delayed secondary pump pulse to effectively increase the pump spectral width inside the cavity. This enables on-chip generation of heralded single photons with state purities in excess of 99% without spectral filtering. PMID- 29444013 TI - Metallic gyroids with broadband circular dichroism. AB - Circular dichroism is a useful property for filtering or separating beams containing opposite spin angular momentum. Of the many geometries exhibiting circular dichroism, the gyroid has proven to be an excellent template for exploring circular dichroism in three dimensions. However, the bandwidth of the circular dichroism from dielectric gyroids is limited by its narrow circularly polarized stop band. Here we investigate conductive silver gyroid micro structures using direct laser writing of polymeric templates followed by the electroless deposition of a uniform silver coating. We show that the transformation from dielectric to silver gyroid micro-structure can increase the circular dichroism bandwidth by close to a factor of 3. PMID- 29444014 TI - Intensity noise behavior of an InAs/InGaAs quantum dot laser emitting on ground states and excited states. AB - We experimentally and numerically study the amplitude stability of an InAs/InGaAs quantum dot laser emitting simultaneously on ground states (GSs) and excited state (ESs) at center wavelengths of 1245 and 1168 nm, respectively. The stability is quantified by a spectrally resolved noise current analysis that is dependent on the laser injection current. We find a non-monotonic behavior of the amplitude noise which shows a reduction of up to 4 dB when the GS and ES emit simultaneously. Simulations based on a rate equation model confirm the reduction in noise and suggest the cascaded GS and ES carrier paths as the relevant underlying mechanism. PMID- 29444015 TI - Transmission out-of-plane interferometer to study thermal distributions in liquids. AB - An optical setup that does not need in-line alignment of the object illumination and camera sensor, or requires a reflection mirror after the sample, is introduced to observe the optical phase in a heating liquid. This system uses an out-of-plane transmission digital holographic interferometer that uniformly adds speckle to the image holograms by means of a neutral phase screen. The way in which the liquid is illuminated allows having a variable magnification of the observed area of the sample. As a proof of principle, a thermal time-dependent distribution experiment is presented, whose resulting optical phase readily depicts the temperature-time-varying distribution in the liquid. PMID- 29444016 TI - Phase-synchronous undersampling in nonlinear spectroscopy. AB - We introduce the concept of phase-synchronous undersampling in nonlinear spectroscopy. The respective theory is presented and validated experimentally in a phase-modulated quantum beat experiment by sampling high phase modulation frequencies with low laser repetition rates. The advantage of undersampling in terms of signal quality and reduced acquisition time is demonstrated, and breakdown conditions are identified. The presented method is particularly beneficial for experimental setups with limited signal/detection rates. PMID- 29444017 TI - Kerr lens mode-locked Yb:CALGO thin-disk laser. AB - We demonstrate the first Kerr lens mode-locked Yb:CaGdAlO4 (Yb:CALGO) thin-disk laser oscillator. It generates pulses with a duration of 30 fs at a central wavelength of 1048 nm and a repetition rate of 124 MHz. The laser emits the shortest pulses generated by a thin-disk laser oscillator, equal to the shortest pulse duration obtained by Yb-doped bulk oscillators. The average output power is currently limited to 150 mW by the low gain and limited disk quality. We expect that more suitable Yb:CALGO disks will enable substantially higher power levels with similar pulse durations. PMID- 29444018 TI - Recovering a hidden polarization by ghost polarimetry. AB - By exploiting polarization correlations of light from a broadband fiber-based amplified spontaneous emission source we succeed in reconstructing a hidden polarization in a ghost polarimetry experiment in close analogy to ghost imaging and ghost spectroscopy. Thereby, an original linear polarization state in the object arm of a Mach-Zehnder interferometer configuration which has been camouflaged by a subsequent depolarizer is recovered by correlating it with light from a reference beam. The variation of a linear polarizer placed inside the reference beam results in a Malus law type second-order intensity correlation with high contrast, thus measuring a ghost polarigram. PMID- 29444019 TI - Group refractive index quantification using a Fourier domain short coherence Sagnac interferometer. AB - The group refractive index is important in length calibration of Fourier domain interferometers by transparent transfer standards. We demonstrate accurate group refractive index quantification using a Fourier domain short coherence Sagnac interferometer. Because of a justified linear length calibration function, the calibration constants cancel out in the evaluation of the group refractive index, which is then obtained accurately from two uncalibrated lengths. Measurements of two standard thickness coverslips revealed group indices of 1.5426+/-0.0042 and 1.5434+/-0.0046, with accuracies quoted at the 95% confidence level. This agreed with the dispersion data of the coverslip manufacturer and therefore validates our method. Our method provides a sample specific and accurate group refractive index quantification using the same Fourier domain interferometer that is to be calibrated for the length. This reduces significantly the requirements of the calibration transfer standard. PMID- 29444020 TI - Highly sensitive selectively coated photonic crystal fiber-based plasmonic sensor. AB - Highly sensitive and miniaturized sensors are highly desirable for real-time analyte/sample detection. In this Letter, we propose a highly sensitive plasmonic sensing scheme with the miniaturized photonic crystal fiber (PCF) attributes. A large cavity is introduced in the first ring of the PCFs for the efficient field excitation of the surface plasmon polariton mode and proficient infiltration of the sensing elements. Due to the irregular air-hole diameter in the first ring, the cavity exhibits the birefringence behavior which enhances the sensing performance. The novel plasmonic material gold has been used considering the chemical stability in an aqueous environment. The guiding properties and the effects of the sensing performance with different parameters have been investigated by the finite element method, and the proposed PCFs have been fabricated using the stack-and-draw fiber drawing method. The proposed sensor performance was investigated based on the wavelength and amplitude sensing techniques and shows the maximum sensitivities of 11,000 nm/RIU and 1,420 RIU-1, respectively. It also shows the maximum sensor resolutions of 9.1*10-6 and 7*10-6 RIU for the wavelength and amplitude sensing schemes, respectively, and the maximum figure of merits of 407. Furthermore, the proposed sensor is able to detect the analyte refractive indices in the range of 1.33-1.42; as a result, it will find the possible applications in the medical diagnostics, biomolecules, organic chemical, and chemical analyte detection. PMID- 29444021 TI - Subwavelength-grating contradirectional couplers for large stopband filters. AB - Manipulating the coupling coefficient at subwavelength scales provides an additional degree of freedom in designing integrated Bragg gratings. We demonstrate asymmetric contradirectional couplers (contra-DCs) using sidewall corrugated subwavelength grating (SWG) waveguides for broadband add-drop Bragg filters. We show that a SWG can effectively increase the overlap of coupled modes and thus the photonic band gap. The measured spectra show good agreement with the prediction of photonic band structure simulations. A record bandwidth of 4.07 THz (33.4 nm) has been achieved experimentally. A four-port Bragg resonating filter made of a phase-shifted Bragg grating SWG contra-DC is also demonstrated for narrow-band (near 100 GHz) filtering. All these devices are achieved on the 220 nm silicon-on-insulator platform with a compact length of less than 150 MUm. These large stopband filters may find important applications such as band splitting, reconfigurable channel band switching, bandwidth-tunable filtering, and dispersion engineering. PMID- 29444022 TI - Optical rewritable liquid crystal displays without a front polarizer. AB - A front polarizer-free optically rewritable (ORW) liquid crystal display (LCD) has been made via a hybrid alignment configuration with dye-doped LCs. The hybrid structure consists of one optically active planar and one optically passive homeotropic alignment layer. The rewritability of the device is achieved by photo reorienting the azo dye molecules in the active planar alignment layer. The dye is doped in LCs to function as a polarizer by following the LCs' direction via a guest-host effect so that the front polarizer can be eliminated. This makes the device more compact and easier to operate for image erasing and rewriting. The image rewriting time only requires ~9.0 s, which is determined by the exposure energy and LC parameters. The hybrid-mode dye-doped ORW LCD devices could find applications in E-paper, transparent display, and various photonics devices. PMID- 29444023 TI - Radiation hardness of Ce-doped sol-gel silica fibers for high energy physics applications. AB - The results of irradiation tests on Ce-doped sol-gel silica using x- and gamma rays up to 10 kGy are reported in order to investigate the radiation hardness of this material for high-energy physics applications. Sol-gel silica fibers with Ce concentrations of 0.0125 and 0.05 mol. % are characterized by means of optical absorption and attenuation length measurements before and after irradiation. The two different techniques give comparable results, evidencing the formation of a main broad radiation-induced absorption band, peaking at about 2.2 eV, related to radiation-induced color centers. The results are compared with those obtained on bulk silica. This study reveals that an improvement of the radiation hardness of Ce-doped silica fibers can be achieved by reducing Ce content inside the fiber core, paving the way for further material development. PMID- 29444024 TI - Real-time spectral characterization of a photon pair source using a chirped supercontinuum seed. AB - Photon pair sources have wide ranging applications in a variety of quantum photonic experiments and protocols. Many of these protocols require well controlled spectral correlations between the two output photons. However, due to low cross-sections, measuring the joint spectral properties of photon pair sources has historically been a challenging and time-consuming task. Here, we present an approach for the real-time measurement of the joint spectral properties of a fiber-based four wave mixing source. We seed the four wave mixing process using a broadband chirped pulse, studying the stimulated process to extract information regarding the spontaneous process. In addition, we compare stimulated emission measurements with the spontaneous process to confirm the technique's validity. Joint spectral measurements have taken many hours historically and several minutes with recent techniques. Here, measurements have been demonstrated in 5-30 s depending on resolution, offering substantial improvement. Additional benefits of this approach include flexible resolution, large measurement bandwidth, and reduced experimental overhead. PMID- 29444025 TI - All-dielectric reflective half-wave plate metasurface based on the anisotropic excitation of electric and magnetic dipole resonances. AB - We present an all-dielectric metasurface that simultaneously supports electric and magnetic dipole resonances for orthogonal polarizations. At resonances, the metasurface reflects the incident light with nearly perfect efficiency and provides a phase difference of pi in the two axes, making a low-loss half-wave plate in reflection mode. The polarization handedness of the incident circularly polarized light is preserved after reflection; this is different from either a pure electric mirror or magnetic mirror. With the features of high reflection and circular polarization conservation, the metamirror is an ideal platform for the geometric phase-based gradient metasurface functioning in reflection mode. Anomalous reflection with the planar meta-mirror is demonstrated as a proof of concept. The proposed meta-mirror can be a good alternative to plasmonic metasurfaces for future compact and high-efficiency metadevices for polarization and phase manipulation in reflection mode.

PMID- 29444027 TI - Controllable photonic crystal with periodic Raman gain in a coherent atomic medium. AB - With two sets of standing-wave fields built in a thermal rubidium vapor cell, we have established a controllable photonic crystal with periodic gain in a coherently prepared N-type four-level atomic configuration. First, the photonic lattice constructed by a resonant standing-wave coupling field results in a spatially modulated susceptibility and makes the signal field diffract in a discrete manner under the condition of electromagnetically induced transparency. Then, with the addition of the standing-wave pump field, the N-type atomic medium can induce a periodic Raman gain on the signal field, which can be effectively controlled by tuning the pertinent atomic parameters. The experimental demonstration of such a real-time reconfigurable photonic crystal structure with periodic Raman gain can pave the way for realizing desired applications predicted in the gain-modulated periodic optical systems. PMID- 29444028 TI - Doughnut-shaped emission from vertical organic nanowire coupled to thin plasmonic film. AB - Vertical nanowires facilitate an innovative mechanism to channel the optical field in the orthogonal direction and act as a nanoscale light source. Subwavelength, vertically oriented nanowire platforms, both of plasmonic and semiconducting variety, can facilitate interesting far-field emission profiles and potentially carry orbital angular momentum states. Motivated by these prospects, in this Letter, we show how a hybrid plasmonic-organic platform can be harnessed to engineer far-field radiation. The system that we have employed is an organic nanowire made of diaminoanthroquinone grown on a plasmonic gold film. We experimentally and numerically studied angular distribution of surface plasmon polariton mediated emission from a single, vertical organic nanowire by utilizing evanescent excitation and Fourier plane microscopy. Photoluminescence and elastic scattering from a single nanowire was analyzed individually in terms of inplane momentum states of the outcoupled photons. We found that the emission is doughnut shaped in both photoluminescence and elastic scattering regimes. We anticipate that the discussed results can be relevant in designing efficient, polariton mediated nanoscale photon sources that can carry orbital angular momentum states.

AB - Asymmetric nanophotonic structures enable a wide range of opportunities in optical nanotechnology because they support efficient optical nonlinearities mediated by multiple plasmon resonances over a broad spectral range. The Archimedean nanospiral is a canonical example of a chiral plasmonic structure because it supports even-order nonlinearities that are not generally accessible in locally symmetric geometries. However, the complex spiral response makes nanoscale experimental characterization of the plasmonic near-field structure highly desirable. Here we employ high-efficiency, high-spatial-resolution cathodoluminescence imaging in a scanning transmission electron microscope to describe the spatial, spectral, and polarization response of plasmon modes in the nanospiral geometry. PMID- 29444030 TI - Tomography of asymmetric molecular orbitals with a one-color inhomogeneous field. AB - We demonstrate image asymmetric molecular orbitals via high-order harmonic generation in a one-color inhomogeneous field. Due to the broken inversion symmetry of the inhomogeneous field in space, the returning electrons with energy in a broad range can be forced to recollide from only one direction for all the orientation angles of molecules, which therefore can be used to reconstruct asymmetric molecular orbitals. Following the procedure of molecular orbital tomography, the highest occupied molecular orbital of carbon monoxide (CO) is satisfactorily reconstructed with high-order harmonic spectra driven by the inhomogeneous field. This scheme is helpful to relax the requirement of laser conditions and is also applicable to other asymmetric molecules.

AB - We present optical vector network analysis (OVNA) of an isotopically purified Er1663+:LiYF47 crystal. The OVNA method is based on generation and detection of a modulated optical sideband by using a radio-frequency vector network analyzer. This technique is widely used in the field of microwave photonics for the characterization of optical responses of optical devices such as filters and high Q resonators. However, dense solid-state atomic ensembles induce a large phase shift on one of the optical sidebands that results in the appearance of extra features on the measured transmission response. We present a simple theoretical model that accurately describes the observed spectra and helps to reconstruct the absorption profile of a solid-state atomic ensemble as well as corresponding change of the refractive index in the vicinity of atomic resonances. PMID- 29444032 TI - Two-dimensional electronic-Raman spectroscopy. AB - We present a new technique, two-dimensional electronic-Raman spectroscopy (2DER), which combines femtosecond stimulated Raman spectroscopy and a pulse-shaper assisted 2D spectroscopic scheme for the actinic pump. The 2DER spectrum presents the initial actinic excitation wavelength with nanometer spectral resolution in the first axis and the detected stimulated Raman spectra in the second axis. We measured the correlation of the electronic and vibrational states in the photosynthetic accessory pigment beta-carotene and reveal its photoexcited state manifold.

AB - A high-power, high-repetition-rate, broadband tunable femtosecond optical parametric oscillator (OPO) is constructed based on KTiOAsO4 crystal, pumped by a 75.5 MHz mode-locked Yb:KGW laser. With 7 W pump power, the OPO generates as much as 2.32 W of signal power at 1.55 MUm and 1.31 W of idler power at 3.05 MUm, corresponding to a total conversion efficiency of 51.8%. Operating at 151 MHz repetition rate, the wavelength of the signal covers 1.41-1.71 MUm with a tunable idler range of 2.61-3.84 MUm. The idler bandwidth is more than 180 nm over the entire mid-infrared range. By compensating intracavity dispersion, the signal pulse has a nearly Fourier transform-limited duration of 129 fs at 1.52 MUm.

AB - Photoacoustic microscopy (PAM) with ultraviolet (UV) laser illumination has recently been demonstrated as a promising tool that provides fast, label-free, and multilayered histologic imaging of human breast tissue. Thus far, the axial resolution has been determined ultrasonically. To enable optically defined axial resolution, we exploit the Gruneisen relaxation (GR) effect. By imaging mouse brain slices, we show that GRUV-PAM reveals detailed information about three dimensional cell nuclear distributions and internal structures, which are important diagnostic features for cancers. Due to the nonlinear effect, GRUV-PAM also provides better contrast in images of cell nuclei. PMID- 29444035 TI - Power scalable 10 W 976 nm single-frequency linearly polarized laser source. AB - A 10 W level 976 nm single-frequency linearly polarized laser source was demonstrated with a two-stage all-fiber amplifier configuration. The continuous wave output power of 10.1 W was obtained from the second stage amplifier by using a 20/130 MUm single-mode, polarization maintaining, 1.5 wt. % ytterbium-doped phosphate double-clad fiber. This all-fiber single-frequency laser source is very promising for watt-level deep ultraviolet laser generation via frequency quadrupling. PMID- 29444036 TI - Pulse carving using nanocavity-enhanced nonlinear effects in photonic crystal Fano structures. AB - We experimentally demonstrate the use of a photonic crystal Fano resonance for carving-out short pulses from long-duration input pulses. This is achieved by exploiting an asymmetric Fano resonance combined with carrier-induced nonlinear effects in a photonic crystal membrane structure. The use of a nanocavity concentrates the input field to a very small volume leading to an efficient nonlinear resonance shift that carves a short pulse out of the input pulse. Here, we demonstrate shortening of ~500 ps and ~100 ps long pulses to ~30 ps and ~20 ps pulses, respectively. Furthermore, we demonstrate error-free low duty cycle return-to-zero signal generation at 2 Gbit/s with energy consumption down to ~1 pJ/bit and power penalty of ~2 dB. The device physics and limitations are analyzed using nonlinear coupled-mode theory.

AB - In this Letter, we describe spatially switched surface plasmon microscopy (ssSPM) based on two-channel momentum sampling. The performance evaluated with periodic nanowires in comparison with conventional SPM and bright-field microscopy shows that the resolution of ssSPM is enhanced by almost 15 times over conventional SPM. ssSPM provides an extremely simple way to attain diffraction limit in SPM and to go beyond for super-resolution in label-free microscopy techniques.

AB - A phosphor-in-glass (PiG) with red and green phosphors using Nd-doped glass as a host matrix was fabricated to produce a white light emitting diode (wLED) with a wide color gamut. The Lu3Al5O12:Ce3+ and CaAlSiN3:Eu2+ contents were adjusted to achieve white emission for liquid crystal display (LCD) applications. The silicate glass was doped with varying concentrations of Nd2O3 to modify the photoluminescence spectra of the wLED, by the hypersensitive absorption of the Nd3+:I9/24->G5/24,G27/2 transition. The color coordination, the color rendering index, and the color co-related temperature of the PiG-mounted LEDs were modified by the introduction of Nd3+. The color gamut of the wLED was monitored and found to have effectively improved with the Nd3+-doped silicate glass. PMID- 29444039 TI - Programmable quantum random number generator without postprocessing. AB - We demonstrate a viable source of unbiased quantum random numbers whose statistical properties can be arbitrarily programmed without the need for any postprocessing such as randomness distillation or distribution transformation. It is based on measuring the arrival time of single photons in shaped temporal modes that are tailored with an electro-optical modulator. We show that quantum random numbers can be created directly in customized probability distributions and pass all randomness tests of the NIST and Dieharder test suites without any randomness extraction. The min-entropies of such generated random numbers are measured close to the theoretical limits, indicating their near-ideal statistics and ultrahigh purity. Easy to implement and arbitrarily programmable, this technique can find versatile uses in a multitude of data analysis areas. PMID- 29444040 TI - Self-assembled monolayers of bimetallic Au/Ag nanospheres with superior surface enhanced Raman scattering activity for ultra-sensitive triphenylmethane dyes detection. AB - The bimetallic Au/Ag self-assembled monolayers (SAMs) were constructed by using mono-dispersed Au/Ag nanospheres (Ag: 4.07%-34.53%) via evaporation-based assembly strategy. The composition-dependent surface-enhanced Raman scattering (SERS) spectroscopy revealed that the Au/Ag (Ag: 16.83%) SAMs provide maximized activity for triphenylmethane dyes detection. With the inter-metallic synergy, the optimized SAMs enable the Raman intensity of crystal violet molecules to be about 223 times higher than that of monometallic Au SAMs. Moreover, the SERS signals with excellent uniformity (<5% variation) are sensitive down to 10-13 M concentrations because of the optimal matching between bimetallic plasmon resonance and the incident laser wavelength. PMID- 29444041 TI - Refractive index sensor based on graphene-coated photonic surface-wave resonance. AB - We propose a graphene-coated photonic system with the excitation of Bloch surface waves (BSWs) for refractive index sensing. Through manipulation of the BSW resonance in the truncated photonic crystal under a Kretschmann configuration, the absorption in a graphene monolayer is significantly enhanced, assisted by the strong electromagnetic confinement of BSWs. The sharp and low reflectivity dip and the strong wave-environment interaction enable highly sensitive optical sensing. First-order perturbation theory and transfer-matrix calculation indicate that the system sensitivity is strongly related to the ratio of the electric field energy in the detection area, operation wavelength, and incident angle. Study shows that the wavelength sensitivity and figure of merit of the optimized system can reach 7023 nm/RIU and 196.44, respectively. More generalized BSW system configurations, e.g., aperiodic BSW design, are proposed for refractive index sensing application.

AB - We demonstrate vacuum squeezing at the D1 line of atomic rubidium (795 nm) with a tunable, doubly-resonant, monolithic subthreshold optical parametric oscillator in periodically-poled Rb-doped potassium titanyl phosphate (ppRKTP). The squeezing appears to be undiminished by a strong dispersive optical nonlinearity recently observed in this material. PMID- 29444043 TI - Single-mode ultraviolet whispering gallery mode lasing from a floating GaN microdisk. AB - We fabricated a floating GaN microdisk supported by a silicon pillar through photolithography, dry-etching GaN, and isotropic wet-etching silicon methods. Single-mode ultraviolet whispering gallery mode (WGM) lasing was obtained from the floating GaN microdisk under optical pumping conditions at room temperature. The features of WGM lasing, i.e., the threshold, emission intensity, and lasing mode number, were characterized. A two-dimensional finite-difference time-domain simulation about the optical field contour profile also confirmed the resonance mechanism of WGM lasing. This work can help realize single-mode WGM lasing with high quality factor and low threshold. PMID- 29444044 TI - Intensity statistics in a long random fiber Raman laser. AB - We study the output emission statistics of a random continuous-wave Raman fiber laser. The signal evolution is governed by a generalized nonlinear Schrodinger equation (NLSE) with inserted gain. The statistics are close to the Rayleigh one, and the deviations are caused by the Kerr nonlinearity. To characterize the deviations, we analytically find the mean of the squared output signal intensity, based on the kinetic theory. We show qualitative agreement with available experimental data and supplement the results with numerical calculations. With the limit of small gain, the kinetic theory gives a finite answer for the mean of squared intensity in the first and the second order with respect to small nonlinearity. The result is consistent with the fact that the NLSE is integrable in the case of zero gain and is applicable to any generalized NLSE if the inserted terms are effectively small. PMID- 29444045 TI - Few-period helically twisted all-solid photonic bandgap fibers. AB - We present a type of few-period helically twisted all-solid photonic bandgap fiber (AS-PBGFs). The helical structure leads to orbital resonance of a cladding rod light, which couples with the core mode. A two-period twist structure exhibits an extremely strong resonant dip of up to 30 dB. A series of samples with twist periods of 3.31-7.92 mm (yielding twist rates of 1.90-0.79 rad?mm-1) in association with different resonance orders are fabricated and demonstrated. The inherent physical mechanism underlying the resonance is analyzed. Moreover, the responses of the resonance to mechanical torsion, strain, and temperature are investigated. The twisted AS-PBGFs feature high reproducibility, stability, and robustness, and have great potential in tunable in-fiber filters and sensors. PMID- 29444046 TI - On-chip optical transduction scheme for graphene nano-electro-mechanical systems in silicon-photonic platform. AB - We present a scheme for on-chip optical transduction of strain and displacement of graphene-based nano-electro-mechanical systems (NEMS). A detailed numerical study on the feasibility of three silicon-photonic integrated circuit configurations is presented: the Mach-Zehnder interferometer (MZI), the micro ring resonator, and the ring-loaded MZI. An index sensing based technique using an MZI loaded with a ring resonator with a moderate Q-factor of 2400 can yield a sensitivity of 28 fm/Hz and 6.5*10-6%/Hz for displacement and strain, respectively. Though any phase-sensitive integrated-photonic device could be used for optical transduction, here we show that optimal sensitivity is achievable by combining resonance with phase sensitivity. PMID- 29444047 TI - Homographically generated light sheets for the microscopy of large specimens. AB - We compare the performance of linear and nonlinear methods for aligning the excitation and detection planes throughout volumes of large specimens in digitally scanned light sheet microscopy. An effective nonlinear method involves the registration of four corner extrema of the imaging volume via a projective transform. We show that this improves the light collection efficiency of the commonly used three-point affine registration by an average of 42% over a typical specimen volume. Accurate illumination/detection registration methods are now pertinent to biological research in view of current trends towards imaging large or expanded samples, at depth, with diffraction limited resolution.

AB - We produce extremely bright mid-infrared (mid-IR) pulses with a tunable wavelength of 7 MUm to 15 MUm through difference frequency generation. Optimization of beam quality and beam focusing results in an intense mid-IR field spatiotemporally confined in the lambda-cubic volume. A near planar wavefront is achieved through manipulating the wavefront curvature of the pumping pulse in the frequency downconversion process. Coherent mid-IR pulses are produced with the peak field of 280 MV/cm at 10 MUm, and its intensity exceeds 100 TW/cm2, estimated from measured pulse energy, and spatial and temporal pulse profiles. Interaction of such an intense mid-IR field with Xe and Kr gas forms plasma and generates a supercontinuum in the visible range.

AB - We report the fabrication of large-area holographic diffraction gratings on a curved surface from transferred photopolymer films by introducing a water-soluble interlayer. The holographic gratings on a curved surface have a diffraction efficiency of ~63%, which is ~80% of the recorded holographic film on a flat surface. By transferring a recorded holographic grating to a flat substrate, we obtained rainbow holographic gratings under white light illumination. This can be explained by the deformation of the holographic gratings. Our result provides a low-cost method for fabricating diffraction optical elements on a curved surface for optical systems. PMID- 29444050 TI - Bioresorbable optical fiber Bragg gratings. AB - We demonstrate, for the first time, an inscription and wet dissolution study of Bragg gratings in a bioresorbable calcium-phosphate glass optical fiber. Bragg gratings, with average refractive index changes of 5.8*10-4, were inscribed using 193 nm excimer laser radiation. Results on the dissolution of the irradiated fiber in simulated physiological conditions are presented after immersing a tilted Bragg grating in a phosphate buffered saline solution for 56 h; selective chemical etching effects are also reported. The investigations performed pave the way toward the use of such phosphate glass fiber Bragg gratings for the development of soluble photonic sensing probes for the efficient in vivo monitoring of vital mechanical or chemical parameters. PMID- 29444051 TI - Ultrasensitive measurement of gas refractive index using an optical nanofiber coupler. AB - We report an ultrasensitive gas refractive index (RI) sensor based on optical nanofiber couplers (ONCs). Theoretical analysis reveals that a dispersion turning point (DTP) exists when the diameter of the coupler is below 1000 nm. Leveraging this DTP, the gas RI sensitivity can be significantly improved to infinity. Then we experimentally demonstrate a DTP and achieve ultrahigh sensitivities of 46,470 nm/refractive index unit (RIU) and -45,550 nm/RIU around the DTP using an ONC with a diameter of 700 nm. More importantly, the unique twin dips/peaks interference characteristics around the DTP offers further enhancement on the sensitivity to 92,020 nm/RIU. The demonstrated sensor not only shows vast potential in ultrasensitive pressure sensing, acoustic sensing, gas sensing, and gas phase biomarker detection, but also provides a new tool for nonlinear optics, ultrafast optics, quantum optics, and ultracold atom optics. PMID- 29444052 TI - Multiple scattering of light in discrete random media using incoherent interactions. AB - We consider the scattering and absorption of light in discrete random media of densely packed spherical particles. In what we term "radiative transfer with reciprocal transactions" (R2T2), we introduce a volume element of the random medium, derive its scattering and absorption characteristics using the superposition T-Matrix method (STMM), and compute its frequency-domain incoherent volume-element scattering characteristics. Using an order-of-scattering approach, we then compute a numerical Monte Carlo solution for the scattering problem with an exact treatment of the interaction between two volume elements. We compute both the direct and reciprocal contributions along a sequence of volume elements, allowing us to evaluate the coherent backscattering effects. We show that the R2T2 and exact STMM solutions are in mutual agreement for large finite systems of densely packed spherical particles. We conclude that the R2T2 method provides a viable numerical solution for scattering by asymptotically infinite systems of particles.

AB - We investigated THz nonreciprocal circularly polarized transmission in thin longitudinally magnetized InSb film, especially focusing on its non-eigen nonreciprocal transmission mechanism at room temperature. Then, based on this effect, we presented a THz isolator for linear polarized waves. The nonreciprocal transmission of the InSb film in this device is converted and enhanced by a pair of orthogonal artificial birefringence gratings. After the optimization, the isolation reaches 24 dB, and the insertion loss is <0.5 dB at room temperature and a low magnetic field.

AB - Thin films are key elements in the current development of nanotechnology, and their characterization has become an essential task. In this Letter, we report on a technique to reconstruct full 3D maps of dielectric thin films using the scattered light of decoupled surface plasmon polaritons. Patterned magnesium fluoride thin films were fabricated, and their 3D thickness map was fully reconstructed with high (<1 nm) precision. This technique can be applied and easily adjusted to identify inhomogeneities in wide areas (mm2-cm2) of dielectric samples with subnanometer precision, or to characterize the fabrication processes involved in the preparation of patterned multilayered systems. PMID- 29444055 TI - Dynamically stable Nd:YAG resonators with beam quality beyond the birefringence limit and pumping of a singly resonant optical parametric oscillator. AB - A simple, reliable, linearly polarized laser source with very high beam quality is demonstrated using standard diode-side-pumped Nd:YAG modules. The laser produced 30 W of output power with beam quality factor M2<1.15 over the entire range of input powers and beam quality of 1.02 at the laser operation point. This is, to our knowledge, the highest beam quality for a dynamically stable high power laser that uses an optically isotropic crystal. The laser was used as a pump source for an optical parametric oscillator based on a periodically poled lithium niobate, producing wavelength in the 1.5-3.8 MUm range.

AB - Multiphoton microscopy (MPM) has been widely used for three-dimensional biological imaging. Here, based on the photon-induced charge state conversion process, we demonstrated a low-power high-resolution MPM with a nitrogen vacancy (NV) center in diamond. Continuous wave green and orange lasers were used to pump and detect the two-photon charge state conversion, respectively. The power of the laser for multiphoton excitation was 40 MUW. Both the axial and lateral resolutions were improved approximately 1.5 times compared with confocal microscopy. The results can be used to improve the resolution of the NV center based quantum sensing and biological imaging. PMID- 29444057 TI - Measurement of the surface susceptibility and the surface conductivity of atomically thin MoS2 by spectroscopic ellipsometry. AB - We show how to correctly extract from the ellipsometric data the surface susceptibility and the surface conductivity that describe the optical properties of monolayer MoS2. Theoretically, these parameters stem from modelling a single layer two-dimensional crystal as a surface current, a truly two-dimensional model. Current experimental practice is to consider this model equivalent to a homogeneous slab with an effective thickness given by the interlayer spacing of the exfoliating bulk material. We prove that the error in the evaluation of the surface susceptibility of monolayer MoS2, owing to the use of the slab model, is at least 10% or greater, a significant discrepancy in the determination of the optical properties of this material. PMID- 29444058 TI - High-order super-resolution optical fluctuation imaging based on low-pass denoising. AB - A new scheme of super-resolution optical fluctuation imaging (SOFI) is proposed to broaden its application in the high-order case by separating the elimination of shot noise from the computation of cumulant, applying the low-pass denoising (LPD) operator to SOFI. The high-order cumulants are derived from a basic recursion of moments with the suppression of shot noise by the LPD on raw data. SOFI based on LPD (LPD-SOFI) demonstrates a 10.6-fold lateral resolution enhancement with the cumulant order of the 16th and a seven-fold three dimensional resolution enhancement with the cumulant order of the 10th in experiments performed on a sparse sample of quantum dots. PMID- 29444059 TI - 250 W clad pumped Raman all-fiber laser with brightness enhancement. AB - We report a strictly all-fiber clad pumped Raman fiber laser with a CW power of 250 W. To the best of our knowledge, this is the highest power Raman fiber laser demonstrated in any configuration allowing brightness enhancement. In addition, this is the first report of a Raman clad pumped all-fiber laser. The brightness of the pump source was enhanced by a factor of ~3.8. This result was achieved by the design of a novel triple-clad fiber, with tight pump power inner confining clad that both maximized the Raman gain and inhibited the second Stokes radiation. We discuss power-increase effects on the beam quality, efficiency, and brightness enhancement.

AB - Shot-noise-limited Doppler-broadened (Db) noise-immune cavity-enhanced optical heterodyne molecular spectrometry (NICE-OHMS) has been realized by implementation of balanced detection. A characterization of the system based on Allan-Werle plots of the absorption coefficient, retrieved by fitting a model function to data, shows that the system has a white noise equivalent absorption per unit length per square root of bandwidth of 2.3*10-13 cm-1 Hz-1/2, solely 44% above the shot noise limit, and a detection sensitivity of 2.2*10-14 cm-1 over 200 s, both being unprecedented for Db NICE-OHMS. The white noise response follows the expected inverse square root dependence on power that is representative of a shot noise-limited response, which confirms that the system is shot-noise-limited.

AB - We report an on-chip autocorrelator comprising a Si rib waveguide and two-photon absorption photodiodes in which two pulses simultaneously propagate in opposite directions, and their correlation is acquired. The rib waveguide's broadband guiding mode and moderately low group index allow the device to operate over a wide wavelength range with high resolution. We confirm that the waveguide has a transmission band of at least 1300-1630 nm and observed correlation waveforms for pulses of the order of several hundred femtoseconds to several picoseconds, with a range of at least the entire C band region. PMID- 29444062 TI - 40 Gb/s indoor optical wireless system enabled by a cyclically arranged optical beamsteering receiver. AB - Indoor optical wireless communication with optical beamsteering capability is currently attracting a lot of attention. One major two-dimensional (2D) optical beamsteering scheme is realized by 2D grating or its active counterpart, which is usually based on a spatial light modulator (SLM). However, there is a fundamental trade-off between the field of view (FoV) and power efficiency due to the inherent feature of gratings. In this Letter, we propose a new class of 2D beamsteering, named cyclically arranged optical beamsteering (CAO-BS), which can break that trade-off. Traditional 2D gratings extend the optical beam in the Cartesian coordinates (1D grating in horizontal + 1D grating in vertical), while CAO-BS extends the optical beam in the polar coordinates (1D grating + angular rotation). Since only 1D grating is engaged, the power efficiency increases with the number of grating lobes reduced. In the polar coordinates, the angle rotation tuning in a SLM is quasi-continuous in a full 2pi range. The CAO-BS is demonstrated at the receiving end in an indoor experimental system. The FoV is 18 degrees by 360 degrees in polar coordinates without any additional mechanical parts. Based on the CAO-BS, 40 Gbit/s on-off keying data is also successfully transmitted over 1 km single-mode fiber and 0.5 m free space. PMID- 29444063 TI - Ultrahigh-resolution and wideband optical vector analysis for arbitrary responses. AB - An ultrahigh-resolution and wideband optical vector analyzer (OVA) with the simplest architecture, to the best of our knowledge, is proposed and demonstrated based on chirped optical double-sideband (ODSB) modulation in a single-drive Mach Zehnder modulator (MZM). To distinguish the magnitude and phase information carried by the two sidebands in the ODSB signal, a two-step measurement, in which biasing, respectively, the MZM at two different points is applied. Because no optical filtering is required in the scheme, the optical carrier can be located at any wavelength that is suitable for accurate measurement, e.g., close to the notch of a notch response or within the passband of a bandpass response, so the proposed OVA has the capability to measure an arbitrary response. An experiment is carried out, which achieves the magnitude and phase responses of a programmable optical processor with bandpass, notch, or falling-edge responses. The measurement bandwidth is 134 GHz, and the measurement resolution is 1.12 MHz. PMID- 29444064 TI - Optimized random phase only holograms. AB - We propose a simple and efficient technique capable of generating Fourier phase only holograms with a reconstruction quality similar to the results obtained with the Gerchberg-Saxton (G-S) algorithm. Our proposal is to use the traditional G-S algorithm to optimize a random phase pattern for the resolution, pixel size, and target size of the general optical system without any specific amplitude data. This produces an optimized random phase (ORAP), which is used for fast generation of phase only holograms of arbitrary amplitude targets. This ORAP needs to be generated only once for a given optical system, avoiding the need for costly iterative algorithms for each new target. We show numerical and experimental results confirming the validity of the proposal. PMID- 29444065 TI - Compact burst-mode Nd:YAG laser for kHz-MHz bandwidth velocity and species measurements.

A directly modulated diode laser seed source is used to generate 10 ms duration arbitrary sequences of 500 kHz doublet or MHz singlet pulses for flow-field velocity or species measurements, respectively. Flexible pulse widths are used to balance the energy distribution of pulse doublets and achieve second-harmonic conversion efficiencies up to 42%.

AB - A dual-wavelength digital holographic phase and fluorescence microscopy system is demonstrated as the decoding and detection platform of an optical thickness encoded suspension array. The phase imaging path is designed to decode optical thickness encoded microcarriers, and the fluorescence imaging path is used to detect the quantitative information of the bound target analytes. The encoding capacity could be more than 100. The decoding reliability of the phase imaging path is verified by a multiplexed immunoassay experiment. The ability for quantitative analysis of the fluorescence imaging path is confirmed by concentration gradient experiments. This method offers high decoding accuracy and high detection sensitivity of label signals. PMID- 29444067 TI - Arbitrary shaping of biphoton correlations using near-field frequency-to-time mapping. AB - Frequency-to-time mapping (FTM) is a technique used to mirror the spectral shape of an optical waveform in the time domain. The regular approach, based on the far field condition, requires large amounts of dispersion for successful mapping. However, when the far-field condition is insurmountable for achieving a desired temporal profile, another technique, termed near-field FTM, can be employed to assist with the mapping. For the first time, we demonstrate a shaper-assisted near-field FTM using entangled photon pairs. By pre-modifying the two-photon spectral amplitude and phase before propagating the photon pairs through dispersion, we can achieve arbitrary temporal correlations in the near-field region. PMID- 29444068 TI - Multi-distance diffuse optical spectroscopy with a single optode via hypotrochoidal scanning. AB - Frequency-domain diffuse optical spectroscopy (FD-DOS) is an established technique capable of determining optical properties and chromophore concentrations in biological tissue. Most FD-DOS systems use either manually positioned, handheld probes or complex arrays of source and detector fibers to acquire data from many tissue locations, allowing for the generation of 2D or 3D maps of tissue. Here, we present a new method to rapidly acquire a wide range of source-detector (SD) separations by mechanically scanning a single SD pair. The source and detector fibers are mounted on a scan head that traces a hypotrochoidal pattern over the sample that, when coupled with a high-speed FD DOS system, enables the rapid collection of dozens of SD separations for depth resolved imaging. We demonstrate that this system has an average error of 4+/ 2.6% in absorption and 2+/-1.8% in scattering across all SD separations. Additionally, by linearly translating the device, the size and location of an absorbing inhomogeneity can be determined through the generation of B-scan images in a manner conceptually analogous to ultrasound imaging. This work demonstrates the potential of single optode diffuse optical scanning for depth resolved visualization of heterogeneous biological tissues at near real-time rates.

Here we propose a simple liquid flow rate sensor by using a tilted fiber Bragg grating (TFBG) as the sensing element. As the water flows in the vicinity of the TFBG along the fiber axis direction, the TFBG's spectrum changes due to its contact with water. By comparing the time-swept spectra of the TFBG in water to that of the TFBG with water flowing over it, a spectral sweep comb was formed, and the flow rate can be detected by selecting a suitable sweeping frequency. The proposed sensor has a high Q-value of over 17,000 for the lower rate and a large detectable range from 0.0058 mm/s to 3.2 mm/s. And the calculated corresponding lower detectable flow rate of 0.03 nL/s is 3 orders magnitude better than that of the current fiber flowmeter. Meanwhile, the proposed sensor has the temperature self-compensation function for the variation of the external temperature. We believe that this simple configuration will open a research direction of the TFBG deriving theory and configuration for lower flow rate measurements for microfluidic chip applications.

AB - We demonstrate a novel all-fiber laser generating cylindrical vector beams with high slope efficiency and low threshold by introducing a long-period fiber grating into the laser cavity. Highly efficient mode conversion is realized by an LPFG at ~1548 nm. Mode selection and spectrum filtering are achieved in combination with a two-mode fiber Bragg grating (TM-FBG). The fiber laser operates at a single wavelength of 1547.95 nm with a 30 dB linewidth of less than 0.18 nm and a side-mode suppression ratio (SMSR) of more than 56 dB. The lasing threshold and slope efficiency of the laser are 24.5 mW and 35.41%, respectively. The output power is 72 mW with an absorbed pump power of 225 mW. The variation of slope efficiency with respect to the reflectivity of the TM-FBG is investigated. Through adjusting the intra-cavity polarization controller, high-purity radially and azimuthally polarized beams are both obtained. PMID- 29444072 TI - Fruit flies are multistable geniuses. AB - Our sensory systems have evolved to provide us with information about the external world. Such information is useful only insofar as it leads to actions that enhance fitness, and thus, the link between sensation and action has been thoroughly studied in many species. In insects, for example, specific visual stimuli lead to highly stereotyped responses. In contrast, humans can exhibit a wide range of responses to the same stimulus, as occurs most notably in the phenomenon of multistable perception. On this basis, one might think that humans have a fundamentally different way of generating actions from sensory inputs, but Toepfer et al. show that flies show evidence of multistable perception as well. Specifically, when confronted with a sensory stimulus that can yield different motor responses, flies switch from one response to another with temporal dynamics that are similar to those of humans and other animals. This suggests that the mechanisms that give rise to the rich repertoire of sensory experience in humans have correlates in much simpler nervous systems. PMID- 29444071 TI - The PHD finger protein Spp1 has distinct functions in the Set1 and the meiotic DSB formation complexes. AB - Histone H3K4 methylation is a feature of meiotic recombination hotspots shared by many organisms including plants and mammals. Meiotic recombination is initiated by programmed double-strand break (DSB) formation that in budding yeast takes place in gene promoters and is promoted by histone H3K4 di/trimethylation. This histone modification is recognized by Spp1, a PHD finger containing protein that belongs to the conserved histone H3K4 methyltransferase Set1 complex. During meiosis, Spp1 binds H3K4me3 and interacts with a DSB protein, Mer2, to promote DSB formation close to gene promoters. How Set1 complex- and Mer2- related functions of Spp1 are connected is not clear. Here, combining genome-wide localization analyses, biochemical approaches and the use of separation of function mutants, we show that Spp1 is present within two distinct complexes in meiotic cells, the Set1 and the Mer2 complexes. Disrupting the Spp1-Set1 interaction mildly decreases H3K4me3 levels and does not affect meiotic recombination initiation. Conversely, the Spp1-Mer2 interaction is required for normal meiotic recombination initiation, but dispensable for Set1 complex mediated histone H3K4 methylation. Finally, we provide evidence that Spp1 preserves normal H3K4me3 levels independently of the Set1 complex. We propose a model where Spp1 works in three ways to promote recombination initiation: first by depositing histone H3K4 methylation (Set1 complex), next by "reading" and protecting histone H3K4 methylation, and finally by making the link with the chromosome axis (Mer2-Spp1 complex). This work deciphers the precise roles of Spp1 in meiotic recombination and opens perspectives to study its functions in other organisms where H3K4me3 is also present at recombination hotspots.

AB - BACKGROUND: Many countries are transitioning from cytology-based to longer interval HPV screening. Trials comparing HPV-based screening to cytology report an increase in CIN2/3 detection at the first screen, and longer-term reductions in CIN3+; however, population level year-to-year transitional impacts are poorly understood. We undertook a comprehensive evaluation of switching to longer interval primary HPV screening in the context of HPV vaccination. We used Australia as an example setting, since Australia will make this transition in December 2017. METHODS: Using a model of HPV vaccination, transmission, natural history and cervical screening, Policy1-Cervix, we simulated the planned transition from recommending cytology every two years for sexually-active women aged 18-20 to 69, to recommending HPV screening every five years for women aged 25-74 years. We estimated rates of CIN2/3, cervical cancer incidence, and mortality for each year from 2005 to 2035, considering ranges for HPV test accuracy and screening compliance in the context of HPV vaccination (current coverage ~82% in females; ~76% in males). FINDINGS: Transient increases are predicted to occur in rates of CIN2/3 detection and invasive cervical cancer in the first two to three years following the screening transition (of 16-24% and 11 14% in respectively, compared to 2017 rates). However, by 2035, CIN2/3 and invasive cervical cancer rates are predicted to fall by 40-44% and 42-51%, respectively, compared to 2017 rates. Cervical cancer mortality rates are predicted to remain unchanged until ~2020, then decline by 34-45% by 2035. Over the period 2018-2035, switching to primary HPV screening in Australia is expected to avert 2,006 cases of invasive cervical cancer and save 587 lives. CONCLUSIONS: Transient increases in detected CIN2/3 and invasive cancer, which may be detectable at the population level, are predicted following a change to primary HPV screening. This is due to improved test sensitivity bringing forward diagnoses, resulting in longer term reductions in both cervical cancer incidence and mortality. Fluctuations in health outcomes due to the transition to a longer screening interval are predicted to occur for 10-15 years, but cervical cancer rates will be significantly reduced thereafter due to the impact of HPV vaccination and HPV screening. In order to maintain confidence in primary HPV screening through the transitional phase, it is important to widely communicate that an initial increase in CIN2/3 and perhaps even invasive cervical cancer is expected after a national transition to primary HPV screening, that this phenomenon is due to increased prevalent disease detection, and that this effect represents a marker of screening success.

AB - [This corrects the article DOI: 10.1371/journal.pgen.1007119.]. PMID- 29444074 TI - Self-crowding of AMPA receptors in the excitatory postsynaptic density can effectuate anomalous receptor sub-diffusion. AB - AMPA receptors (AMPARs) and their associations with auxiliary transmembrane proteins are bulky structures with large steric-exclusion volumes. Hence, self crowding of AMPARs, depending on the local density, may affect their lateral diffusion in the postsynaptic membrane as well as in the highly crowded postsynaptic density (PSD) at excitatory synapses. Earlier theoretical studies considered only the roles of transmembrane obstacles and the AMPAR-binding submembranous scaffold proteins in shaping receptor diffusion within PSD. Using lattice model of diffusion, the present study investigates the additional impacts of self-crowding on the anomalousity and effective diffusion coefficient (Deff) of AMPAR diffusion. A recursive algorithm for avoiding false self-blocking during diffusion simulation is also proposed. The findings suggest that high density of AMPARs in the obstacle-free membrane itself engenders strongly anomalous diffusion and severe decline in Deff. Adding transmembrane obstacles to the membrane accentuates the anomalousity arising from self-crowding due to the reduced free diffusion space. Contrarily, enhanced AMPAR-scaffold binding, either through increase in binding strength or scaffold density or both, ameliorates the anomalousity resulting from self-crowding. However, binding has differential impacts on Deff depending on the receptor density. Increase in binding causes consistent decrease in Deff for low and moderate receptor density. For high density, binding increases Deff as long as it reduces anomalousity associated with intense self-crowding. Given a sufficiently strong binding condition when diffusion acquires normal behavior, further increase in binding causes decrease in Deff. Supporting earlier experimental observations are mentioned and implications of present findings to the experimental observations on AMPAR diffusion are also drawn. PMID- 29444076 TI - Fragmentation of nest and foraging habitat affects time budgets of solitary bees, their fitness and pollination services, depending on traits: Results from an individual-based model. AB - Solitary bees are important but declining wild pollinators. During daily foraging in agricultural landscapes, they encounter a mosaic of patches with nest and foraging habitat and unsuitable matrix. It is insufficiently clear how spatial allocation of nesting and foraging resources and foraging traits of bees affect their daily foraging performance. We investigated potential brood cell construction (as proxy of fitness), number of visited flowers, foraging habitat visitation and foraging distance (pollination proxies) with the model SOLBEE (simulating pollen transport by solitary bees, tested and validated in an earlier study), for landscapes varying in landscape fragmentation and spatial allocation of nesting and foraging resources. Simulated bees varied in body size and nesting preference. We aimed to understand effects of landscape fragmentation and bee traits on bee fitness and the pollination services bees provide, as well as interactions between them, and the general consequences it has to our understanding of the system. This broad scope gives multiple key results. 1) Body size determines fitness more than landscape fragmentation, with large bees building fewer brood cells. High pollen requirements for large bees and the related high time budgets for visiting many flowers may not compensate for faster flight speeds and short handling times on flowers, giving them overall a disadvantage compared to small bees. 2) Nest preference does affect distribution of bees over the landscape, with cavity-nesting bees being restricted to nesting along field edges, which inevitably leads to performance reductions. Fragmentation mitigates this for cavity-nesting bees through increased edge habitat. 3) Landscape fragmentation alone had a relatively small effect on all responses. Instead, the local ratio of nest to foraging habitat affected bee fitness positively through reduced local competition. The spatial coverage of pollination increases steeply in response to this ratio for all bee sizes. The nest to foraging habitat ratio, a strong habitat proxy incorporating fragmentation could be a promising and practical measure for comparing landscape suitability for pollinators. 4) The number of flower visits was hardly affected by resource allocation, but predominantly by bee size. 5) In landscapes with the highest visitation coverage, bees flew least far, suggesting that these pollination proxies are subject to a trade-off between either longer pollen transport distances or a better pollination coverage, linked to how nests are distributed over the landscape rather than being affected by bee size. PMID- 29444077 TI - Peculiar combinations of individually non-pathogenic missense mitochondrial DNA variants cause low penetrance Leber's hereditary optic neuropathy. AB - We here report on the existence of Leber's hereditary optic neuropathy (LHON) associated with peculiar combinations of individually non-pathogenic missense mitochondrial DNA (mtDNA) variants, affecting the MT-ND4, MT-ND4L and MT-ND6 subunit genes of Complex I. The pathogenic potential of these mtDNA haplotypes is supported by multiple evidences: first, the LHON phenotype is strictly inherited along the maternal line in one very large family; second, the combinations of mtDNA variants are unique to the two maternal lineages that are characterized by recurrence of LHON; third, the Complex I-dependent respiratory and oxidative phosphorylation defect is co-transferred from the proband's fibroblasts into the cybrid cell model. Finally, all but one of these missense mtDNA variants cluster along the same predicted fourth E-channel deputed to proton translocation within the transmembrane domain of Complex I, involving the ND1, ND4L and ND6 subunits. Hence, the definition of the pathogenic role of a specific mtDNA mutation becomes blurrier than ever and only an accurate evaluation of mitogenome sequence variation data from the general population, combined with functional analyses using the cybrid cell model, may lead to final validation. Our study conclusively shows that even in the absence of a clearly established LHON primary mutation, unprecedented combinations of missense mtDNA variants, individually known as polymorphisms, may lead to reduced OXPHOS efficiency sufficient to trigger LHON. In this context, we introduce a new diagnostic perspective that implies the complete sequence analysis of mitogenomes in LHON as mandatory gold standard diagnostic approach. PMID- 29444079 TI - Sensitive and less invasive confirmatory diagnosis of visceral leishmaniasis in Sudan using loop-mediated isothermal amplification (LAMP). AB - BACKGROUND: Confirmatory diagnosis of visceral leishmaniasis (VL), as well as diagnosis of relapses and test of cure, usually requires examination by microscopy of samples collected by invasive means, such as splenic, bone marrow or lymph node aspirates. This causes discomfort to patients, with risks of bleeding and iatrogenic infections, and requires technical expertise. Molecular tests have great potential for diagnosis of VL using peripheral blood, but require well-equipped facilities and trained personnel. More user-friendly, and field-amenable options are therefore needed. One method that could meet these requirements is loop-mediated isothermal amplification (LAMP) using the Loopamp Leishmania Detection Kit, which comes as dried down reagents that can be stored at room temperature, and allows simple visualization of results. METHODOLOGY/PRINCIPAL FINDINGS: The Loopamp Leishmania Detection Kit (Eiken Chemical Co., Japan), was evaluated in the diagnosis of VL in Sudan. A total of 198 VL suspects were tested by microscopy of lymph node aspirates (the reference test), direct agglutination test-DAT (in house production) and rK28 antigen-based rapid diagnostic test (OnSite Leishmania rK39-Plus, CTK Biotech, USA). LAMP was performed on peripheral blood (whole blood and buffy coat) previously processed by: i) a direct boil and spin method, and ii) the QIAamp DNA Mini Kit (QIAgen). Ninety seven of the VL suspects were confirmed as cases by microscopy of lymph node aspirates. The sensitivity and specificity for each of the tests were: rK28 RDT 98.81% and 100%; DAT 88.10% and 78.22%; LAMP-boil and spin 97.65% and 99.01%; LAMP-QIAgen 100% and 99.01%. CONCLUSIONS/SIGNIFICANCE: Due to its simplicity and high sensitivity, rK28 RDT can be used first in the diagnostic algorithm for primary VL diagnosis, the excellent performance of LAMP using peripheral blood indicates that it can be also included in the algorithm for diagnosis of VL as a simple test when parasitological confirmatory diagnosis is required in settings that are lower than the reference laboratory, avoiding the need for invasive lymph node aspiration. PMID- 29444078 TI - Multiplex serology for impact evaluation of bed net distribution on burden of lymphatic filariasis and four species of human malaria in northern Mozambique. AB - BACKGROUND: Universal coverage with long-lasting insecticidal nets (LLINs) is a primary control strategy against Plasmodium falciparum malaria. However, its impact on the three other main species of human malaria and lymphatic filariasis (LF), which share the same vectors in many co-endemic areas, is not as well characterized. The recent development of multiplex antibody detection provides the opportunity for simultaneous evaluation of the impact of control measures on the burden of multiple diseases. METHODOLOGY/PRINCIPAL FINDINGS: Two cross sectional household surveys at baseline and one year after a LLIN distribution campaign were implemented in Mecuburi and Nacala-a-Velha Districts in Nampula Province, Mozambique. Both districts were known to be endemic for LF; both received mass drug administration (MDA) with antifilarial drugs during the evaluation period. Access to and use of LLINs was recorded, and household members were tested with P. falciparum rapid diagnostic tests (RDTs). Dried blood spots were collected and analyzed for presence of antibodies to three P. falciparum antigens, P. vivax MSP-119, P. ovale MSP-119, P. malariae MSP-119, and three LF antigens. Seroconversion rates were calculated and the association between LLIN use and post-campaign seropositivity was estimated using multivariate regression. The campaign covered 68% (95% CI: 58-77) of the population in Nacala-a-Velha and 46% (37-56) in Mecuburi. There was no statistically significant change in P. falciparum RDT positivity between the two surveys. Population seropositivity at baseline ranged from 31-81% for the P. falciparum antigens, 3-4% for P. vivax MSP 119, 41-43% for P. ovale MSP-119, 46-56% for P. malariae MSP-119, and 37-76% for the LF antigens. The seroconversion rate to the LF Bm33 antigen decreased significantly in both districts. The seroconversion rate to P. malariae MSP-119 and the LF Wb123 and Bm14 antigens each decreased significantly in one of the two districts. Community LLIN use was associated with a decreased risk of P. falciparum RDT positivity, P. falciparum LSA-1 seropositivity, and P. malariae MSP-119 seropositivity, but not LF antigen seropositivity. CONCLUSIONS/SIGNIFICANCE: The study area noted significant declines in LF seropositivity, but these were not associated with LLIN use. The MDA could have masked any impact of the LLINs on population LF seropositivity. The LLIN campaign did not reach adequately high coverage to decrease P. falciparum RDT positivity, the most common measure of P. falciparum burden. However, the significant decreases in the seroconversion rate to the P. malariae antigen, coupled with an association between community LLIN use and individual-level decreases in seropositivity to P. falciparum and P. malariae antigens show evidence of impact of the LLIN campaign and highlight the utility of using multiantigenic serological approaches for measuring intervention impact. PMID- 29444080 TI - Promising approach to reducing Malaria transmission by ivermectin: Sporontocidal effect against Plasmodium vivax in the South American vectors Anopheles aquasalis and Anopheles darlingi. AB - BACKGROUND: The mosquito resistance to the insecticides threatens malaria control efforts, potentially becoming a major public health issue. Alternative methods like ivermectin (IVM) administration to humans has been suggested as a possible vector control to reduce Plasmodium transmission. Anopheles aquasalis and Anopheles darlingi are competent vectors for Plasmodium vivax, and they have been responsible for various malaria outbreaks in the coast of Brazil and the Amazon Region of South America. METHODS: To determine the IVM susceptibility against P. vivax in An. aquasalis and An. darlingi, ivermectin were mixed in P. vivax infected blood: (1) Powdered IVM at four concentrations (0, 5, 10, 20 or 40 ng/mL). (2) Plasma (0 hours, 4 hours, 1 day, 5, 10 and 14 days) was collected from healthy volunteers after to administer a single oral dose of IVM (200 MUg/kg) (3) Mosquitoes infected with P. vivax and after 4 days was provided with IVM plasma collected 4 hours post-treatment (4) P. vivax-infected patients were treated with various combinations of IVM, chloroquine, and primaquine and plasma or whole blood was collected at 4 hours. Seven days after the infective blood meal, mosquitoes were dissected to evaluate oocyst presence. Additionally, the ex vivo effects of IVM against asexual blood-stage P. vivax was evaluated. RESULTS: IVM significantly reduced the prevalence of An. aquasalis that developed oocysts in 10 to 40 ng/mL pIVM concentrations and plasma 4 hours, 1 day and 5 days. In An. darlingi to 4 hours and 1 day. The An. aquasalis mortality was expressively increased in pIVM (40ng/mL) and plasma 4 hours, 1, 5 10 and 14 days post-intake drug and in An. darlingi only to 4 hours and 1 day. The double fed meal with mIVM by the mosquitoes has a considerable impact on the proportion of infected mosquitoes for 7 days post-feeding. The oocyst infection prevalence and intensity were notably reduced when mosquitoes ingested blood from P. vivax patients that ingested IVM+CQ, PQ+CQ and IVM+PQ+CQ. P. vivax asexual development was considerably inhibited by mIVM at four-fold dilutions. CONCLUSION: In conclusion, whole blood spiked with IVM reduced the infection rate of P. vivax in An. aquasalis and An. darlingi, and increased the mortality of mosquitoes. Plasma from healthy volunteers after IVM administration affect asexual P. vivax development. These findings support that ivermectin may be used to decrease P. vivax transmission. PMID- 29444081 TI - Alpha desynchronization/synchronization during working memory testing is compromised in acute mild traumatic brain injury (mTBI). AB - Diagnosing and monitoring recovery of patients with mild traumatic brain injury (mTBI) is challenging because of the lack of objective, quantitative measures. Diagnosis is based on description of injuries often not witnessed, subtle neurocognitive symptoms, and neuropsychological testing. Since working memory (WM) is at the center of cognitive functions impaired in mTBI, this study was designed to define objective quantitative electroencephalographic (qEEG) measures of WM processing that may correlate with cognitive changes associated with acute mTBI. First-time mTBI patients and mild peripheral (limb) trauma controls without head injury were recruited from the emergency department. WM was assessed by a continuous performance task (N-back). EEG recordings were obtained during N-back testing on three occasions: within five days, two weeks, and one month after injury. Compared with controls, mTBI patients showed abnormal induced and evoked alpha activity including event-related desynchronization (ERD) and synchronization (ERS). For induced alpha power, TBI patients had excessive frontal ERD on their first and third visit. For evoked alpha, mTBI patients had lower parietal ERD/ERS at the second and third visits. These exploratory qEEG findings offer new and non-invasive candidate measures to characterize the evolution of injury over the first month, with potential to provide much-needed objective measures of brain dysfunction to diagnose and monitor the consequences of mTBI. PMID- 29444082 TI - S100B as an antagonist to block the interaction between S100A1 and the RAGE V domain. AB - Ca2+-binding human S100A1 protein is a type of S100 protein. S100A1 is a significant mediator during inflammation when Ca2+ binds to its EF-hand motifs. Receptors for advanced glycation end products (RAGE) correspond to 5 domains: the cytoplasmic, transmembrane, C2, C1, and V domains. The V domain of RAGE is one of the most important target proteins for S100A1. It binds to the hydrophobic surface and triggers signaling transduction cascades that induce cell growth, cell proliferation, and tumorigenesis. We used nuclear magnetic resonance (NMR) spectroscopy to characterize the interaction between S100A1 and the RAGE V domain. We found that S100B could interact with S100A1 via NMR 1H-15N HSQC titrations. We used the HADDOCK program to generate the following two binary complexes based on the NMR titration results: S100A1-RAGE V domain and S100A1 S100B. After overlapping these two complex structures, we found that S100B plays a crucial role in blocking the interaction site between RAGE V domain and S100A1. A cell proliferation assay WST-1 also supported our results. This report could potentially be useful for new protein development for cancer treatment. PMID- 29444083 TI - High fat diet sensitizes fibromyalgia-like pain behaviors in mice via tumor necrosis factor alpha. AB - Fibromyalgia (FM) and obesity are closely related. However, little is known about how obesity contributes to FM. Importantly, adequate evidence has shown that tumor necrosis factor alpha (TNF-alpha) plays a critical role in obesity. Thus, we hypothesized that obesity-induced TNF-alpha release may potentiate FM associated pain. To test this hypothesis, we investigated the role of TNF-alpha in the development of FM-like pain in a mouse model of acid saline injection induced FM. Consistent with previous reports, we showed that repeated acid saline injections induced bilateral mechanical hyperalgesia, and this effect lasted for at least 4 days after acid saline injections. This phenomenon was associated with increased levels of TNF-alpha in plasma, muscles, and spinal cord. Furthermore, we found that 24 weeks of high fat diet treatment significantly potentiated acid saline-induced bilateral mechanical hyperalgesia. High fat diet-treated mice exhibited robustly increased levels of TNF-alpha in plasma, muscles, and spinal cord after acid saline injections compared with low fat diet-treated mice. Additionally, using immunofluorescence staining, we found that the number of TNF alpha positive cells in dorsal root ganglion (DRG) was increased after acid saline injections, and high fat diet treatment further sensitized this increase. Finally, we reported that acid saline-induced FM-like pain behaviors were abolished in TNFRp55-/- mice, confirming the critical role of TNF-alpha in the development of FM-like pain. Taken together, our results suggested that high fat diet treatment may sensitize acid saline-induced FM-like pain via increasing TNF alpha levels in plasma, muscles, and DRG. PMID- 29444084 TI - Attributional style and depressive symptoms in a male prison sample. AB - The reformulated learned helplessness model proposes that people who tend to make internal, stable, and global attributions in response to uncontrollable aversive events are more likely to develop depression. The present study sought to investigate the nature of the relationship between attributional style and depression in a male prison sample. One hundred and one adult male prisoners from four medium security prisons in Ireland completed the Attributional Style Questionnaire and measures of depression (BDI-II) and anxiety (BAI). Severity of self-reported depressive symptoms in the present sample was comparable to other prison and clinical samples, but higher than community samples. Participants were more severely affected by depressive symptoms than anxiety. The original attributional dimensions (i.e. internal, stable, and global) predicted a significant amount of variance in depression, but the model was not significant after controlling for anxiety. A subsequent regression model, comprising attributional dimensions for both negative events and positive events including a measure of 'uncontrollability', accounted for 35% of the variance in depression and the model retained significance while controlling for anxiety. An attributional model of depression may be relevant to the prison population and could provide a valid insight into the development and treatment of depressive symptoms in prisoners. The findings are interpreted in relation to previous research and implications for theory, clinical practice, and rehabilitation are discussed.

AB - Vulnerability, understood as the propensity to be adversely affected, has attained importance in the context of climate change by helping to understand what makes populations and territories predisposed to its impacts. Conditions of vulnerability may vary depending on the characteristics of each territory studied social, environmental, infrastructural, public policies, among others. Thus, the present study aimed to evaluate what makes the municipalities of the state of Amazonas, Brazil, vulnerable to climate change in the context of the largest tropical forest in the world, and which regions of the State are the most susceptible. A Municipal Vulnerability Index was developed, which was used to associate current socio-environmental characteristics of municipalities with climate change scenarios in order to identify those that may be most affected by climate change. The results showed that poor adaptive capacity and poverty had the most influence on current vulnerability of the municipalities of Amazonas with the most vulnerable areas being the southern, northern, and eastern regions of the state. When current vulnerability was related to future climate change projections, the most vulnerable areas were the northern, northeastern, extreme southern, and southwestern regions. From a socio-environmental and climatic point of view, these regions should be a priority for public policy efforts to reduce their vulnerability and prepare them to cope with the adverse aspects of climate change.

AB - Immune clearance of Hepatitis B virus (HBV) is characterized by broad and robust antiviral T cell responses, while virus-specific T cells in chronic hepatitis B (CHB) are rare and exhibit immune exhaustion that includes programmed-death-1 (PD 1) expression on virus-specific T cells. Thus, an immunotherapy able to expand and activate virus-specific T cells may have therapeutic benefit for CHB patients. Like HBV-infected patients, woodchucks infected with woodchuck hepatitis virus (WHV) can have increased hepatic expression of PD-1-ligand-1 (PD L1), increased PD-1 on CD8+ T cells, and a limited number of virus-specific T cells with substantial individual variation in these parameters. We used woodchucks infected with WHV to assess the safety and efficacy of anti-PD-L1 monoclonal antibody therapy (alphaPD-L1) in a variety of WHV infection states. Experimentally-infected animals lacked PD-1 or PD-L1 upregulation compared to uninfected controls, and accordingly, alphaPD-L1 treatment in lab-infected animals had limited antiviral effects. In contrast, animals with naturally acquired WHV infections displayed elevated PD-1 and PD-L1. In these same animals, combination therapy with alphaPD-L1 and entecavir (ETV) improved control of viremia and antigenemia compared to ETV treatment alone, but with efficacy restricted to a minority of animals. Pre-treatment WHV surface antigen (sAg) level was identified as a statistically significant predictor of treatment response, while PD-1 expression on peripheral CD8+ T cells, T cell production of interferon gamma (IFN-gamma) upon in vitro antigen stimulation (WHV ELISPOT), and circulating levels of liver enzymes were not. To further assess the safety of this strategy, alphaPD-L1 was tested in acute WHV infection to model the risk of liver damage when the extent of hepatic infection and antiviral immune responses were expected to be the greatest. No significant increase in serum markers of hepatic injury was observed over those in infected, untreated control animals. These data support a positive benefit/risk assessment for blockade of the PD-1:PD L1 pathway in CHB patients and may help to identify patient groups most likely to benefit from treatment. Furthermore, the efficacy of alphaPD-L1 in only a minority of animals, as observed here, suggests that additional agents may be needed to achieve a more robust and consistent response leading to full sAg loss and durable responses through anti-sAg antibody seroconversion.

AB - Proctophyllodes huitzilopochtlii Atyeo & Braasch 1966 (Acariformes: Astigmata: Proctophyllodidae), a feather mite, was found on feathers collected from five hummingbird species in California. This mite has not been previously documented on feathers from Anna's (Calypte anna [Lesson 1829]) or Black-chinned (Archilochus alexandri [Bourcier & Mulsant 1846]) Hummingbirds. A total of 753 hummingbirds were evaluated for the presence of mites by species (Allen's n = 112; Anna's n = 500; Black-chinned n = 122; Rufous n = 18; Calliope n = 1), sex (males n = 421; females n = 329; 3 unidentified), and age (juvenile n = 199; after-hatch-year n = 549; 5 unidentified). Of these 753 hummingbirds evaluated, mites were present on the rectrices of 40.9% of the birds. Significantly more Anna's Hummingbirds were positive for rectricial mites (59.2%) compared with 8.2% of Black-chinned, 0.9% of Allen's, 5.6% of Rufous Hummingbirds, and 0% for Calliope (p-value < 0.0001). Across all hummingbird species, male hummingbirds (44.9%) had a higher prevalence of rectricial mites compared to female hummingbirds (36.2%; p-value = 0.004), while juvenile hummingbirds (46.2%) had a non-significantly higher prevalence compared to after-hatch-year hummingbirds (39.0%; p-value = 0.089). On average, the percentage of the long axis of the rachis occupied by mites for the outer rectrices (R4 and R5) was 19%, compared to 11% for inner rectrices (R1 and R2), a significant difference (p-value = <0.0001). There was a marginal lack of significance for symmetrical distribution of tail mites with the mean left side percentage of long axis of the rachis occupied by mites being 16% and very close to the mean right side score of 18% (p value = 0.003). The identification of the feather mite species was based on light microscopic morphometry, and mite distribution on feathers was further evaluated using tabletop scanning electron microscopy (TSEM). The hummingbird-feather mite relationship is not well understood, but the specialized TSEM technique may be especially useful in examining natural positioning and developmental aspects of the mites since it allows in situ feather examination of live mites.

AB - Chronic pain is a debilitating problem, and insights in the neurobiology of chronic pain are needed for the development of novel pain therapies. A genome wide association study implicated the 5p15.2 region in chronic widespread pain. This region includes the coding region for FAM173B, a functionally uncharacterized protein. We demonstrate here that FAM173B is a mitochondrial lysine methyltransferase that promotes chronic pain. Knockdown and sensory neuron overexpression strategies showed that FAM173B is involved in persistent inflammatory and neuropathic pain via a pathway dependent on its methyltransferase activity. FAM173B methyltransferase activity in sensory neurons hyperpolarized mitochondria and promoted macrophage/microglia activation through a reactive oxygen species-dependent pathway. In summary, we uncover a role for methyltransferase activity of FAM173B in the neurobiology of pain. These results also highlight FAM173B methyltransferase activity as a potential therapeutic target to treat debilitating chronic pain conditions. PMID- 29444091 TI - A comprehensive meta-analysis of circulation miRNAs in glioma as potential diagnostic biomarker. AB - Glioma is the most common malignant intracranial tumour. Recently, several publications have suggested that miRNAs can be used as potential diagnostic biomarkers of glioma. Here we performed a meta-analysis to identify the diagnostic accuracy of differentially expressed circulating miRNAs in gliomas. Using PubMed, Medline and Cochrane databases, we searched for studies which evaluated a single or panel of miRNAs from circulating blood as potential biomarkers of glioma. Sixteen publications involving 23 studies of miRNAs from serum or plasma met our criteria and were included in this meta-analysis. The pooled diagnostic parameters were calculated by random effect models and overall diagnostic performance of altered miRNAs was illustrated by the summary receiver operator characteristic (SROC) curves. The pooled sensitivity, specificity, positive likelihood ratio (PLR) and negative likelihood ratio (NLR) from each study were calculated. The pooled PLR, NLR and Diagnostic Odds Ratio were 6.39 (95% CI, 4.61-8.87), 0.15 (95% CI, 0.11-0.21) and 41.91 (95% CI, 23.15-75.88), respectively. The pooled sensitivity, specificity and area under the curve (AUC) were 0.87 (95% CI, 0.82-0.91), 0.86 (95% CI, 0.82-0.90) and 0.93 (95% CI, 0.91 0.95), respectively. This meta-analysis demonstrated that circulating miRNAs are capable of distinguishing glioma from healthy controls. Circulating miRNAs are promising diagnostic biomarkers for glioma and can potentially be used as a non invasive early detection. PMID- 29444092 TI - The impact of early life nutrition and housing on growth and reproduction in dairy cattle. AB - Contentious issues in calf rearing include milk feeding practices and single versus group housing. The current study was performed on a high producing 170 Holstein cow dairy farm, to investigate the impact of nutrition and housing on growth and reproduction. Heifer calves (n = 100) were allocated in birth order to one of two commonly used management strategies. All calves received 3-4 litres of dam specific colostrum within 6 hours of birth. Group A calves were group housed from birth and fed milk replacer (MR) ad libitum via a computerised machine utilising a single teat, with weaning commencing at 63 days of age. Group R calves were initially housed in individual pens and received 2.5 litres of MR twice daily via a bucket until 21 days of age when they were group housed and fed 3 litres of MR twice daily via a group trough with weaning commencing at 56 days. From 12 weeks of age onwards, calves in both dietary groups were subject to common nutritional and husbandry protocols. All breeding of heifers was via artificial insemination with no hormonal intervention. Calves were weighed, body condition scored and morphometric measures recorded weekly up till 12 weeks of age then monthly until conception. Pre-weaning growth rates (kg/day) were significantly higher in Group A calves compared to Group R (0.89, 95% CI 0.86 0.93 vs 0.57, 95% CI 0.54-0.6 kg/day P < 0.001) with the most marked differences observed during the first three weeks of life (0.72, 95% CI 0.61-0.82 vs 0.17, 95% CI 0.08-0.26 P < 0.001). Whilst Group A calves gained body condition score (BCS) throughout the pre-weaning phase, Group R calves lost BCS during the first 4 weeks of life. Data suggested that Group R calves supported skeletal growth during this period by catabolising body tissue. Group A calves had a greater risk of disease than group R calves during the pre-weaning phase (diarrhoea: odds ratio 3.86, 95% CI 1.67-8.9; pneumonia: odds ratio 5.80, 95% CI 2.33-14.44) although no calves died during this period. Whilst pneumonia had a significant impact on growth during the study duration (P = 0.008), this was not the case for diarrhoea. Whilst univariate analysis failed to show any statistically significant group differences (P > 0.050) in any of the mean values of measured reproductive parameters, multivariable Cox regression suggested that there was a weak trend (P = 0.072) for Group A animals to achieve first service earlier than their Group R counterparts (62.6 weeks versus 65.3 weeks). Irrespective of dietary group, the hazard for achievement of all measured reproductive parameters, apart from time to puberty, was 20-40% less for heifers borne from multiparous dams compared to heifers from primiparous dams. PMID- 29444093 TI - The high prevalence of playing-related musculoskeletal disorders (PRMDs) and its associated factors in amateur musicians playing in student orchestras: A cross sectional study. AB - OBJECTIVE: Despite the high number of amateur musicians in the general population, little is known about the musculoskeletal health of amateur musicians. Playing a musical instrument is supposed to be a risk factor for the development of musculoskeletal complaints. This study aimed to evaluate playing related musculoskeletal disorders (PRMDs) among amateur musicians playing in student orchestras. DESIGN: A cross-sectional study. PARTICIPANTS: 357 members of eleven Dutch student orchestras across the Netherlands were included in this study. INTERVENTION: A paper-based questionnaire on PRMDs was used. OUTCOME MEASURES: Sociodemographic characteristics and PRMDs were evaluated using an adaptation of the Nordic Musculoskeletal Questionnaire (NMQ) and the music module of the Disabilities of Shoulder and Hand (DASH) questionnaire. RESULTS: The year prevalence of PRMDs among amateur musicians was 67.8%. Female gender, younger age, higher BMI and playing a string instrument were independently associated with a higher prevalence of PRMDs. The left shoulder was affected more frequently in violinists and violists, whereas the right hand and wrist were more frequently affected in woodwind instrumentalists. Of the subjects with PRMDs during the last week, the score of the music module of the DASH was 18.8 (6.3-31.2). DISCUSSION: This study is the first to report on PRMDs and its associated factors in a large group of amateur musicians. The prevalence of PRMDs in amateur musicians is high, however the DASH scores reflect a confined impact of these PRMDs on their functioning as a musician. Preventive measures are needed aiming at reducing PRMDs among amateur musicians. PMID- 29444094 TI - Plate waste of adults in the United States measured in free-living conditions. AB - We analyze food-item level data collected from 50 adults from the United States using the Remote Food Photography Method(r) to provide the first estimates of plate waste gathered from adults across multiple consecutive meals and days in free-living conditions, and during laboratory-based meals with fixed food items and quantities. We find average plate waste in free-living conditions is 5.6 grams (7.7 kcals) per item and that 3.3% of all food selected is returned as plate waste, where the percent waste figure is substantially lower than previously published plate waste estimates gathered primarily from dine-out settings in the United States such as buffets and institutional settings with limited-choice meals (e.g., school cafeterias). Plate waste from the same participants during the laboratory-based meals is significantly higher with an average of 203.2 grams of solid plate waste per meal (531.3 kcals) or 39.1% of the food provided, which is similar to the plate waste percentages found reported in some school cafeteria settings. The amount of plate waste generated in free living conditions is significantly positively associated with portion size selected for an item. In a multivariate analysis that controls for macronutrient profile, items selected from the vegetables, fats/oils/dressings, and grains categories are associated with significantly greater amounts of plate waste per item. We find no significant associations between free-living plate waste and gender, age, race or body mass index but find that women leave more plate waste in the lab meal where portion sizes are pre-determined by the researcher and similar for all respondents. We discuss possible implications of these findings for programs focused on reducing plate waste and food waste among consumers. PMID- 29444095 TI - Social class, social mobility and alcohol-related disorders in Swedish men and women: A study of four generations. AB - OBJECTIVES: To investigate whether and how social class and social mobility in grandparents and parents predict alcohol-related disorders (ARDs) in males and females aged 12+ years, and whether intergenerational social prediction of ARDs varies across time periods. METHODS: The study sample included four successive generations (G) of Swedish families from the Uppsala Birth Cohort Multigenerational Study: G0 born 1851-1912; G1 born 1915-1929; G2 born 1940-1964 and G3 born 1965-1989. Two study populations were created, each consisting of grandparents, parents and offspring: population I 'G0-G1-G2' (offspring n = 18 430) and population II 'G1-G2-G3' (offspring n = 26 469). Registers and archives provided data on ancestors' socio-demographic factors and ARD history, together with offspring ARD development between 1964-2008. Cox regression models examined the hazard of offspring ARD development according to grandparental social class and grandparental-to-parental social trajectories, controlling for offspring birth year, grandmother's and mother's marital status and parental ARDs. RESULTS: Disadvantaged grandparental social class predicted increased ARD risk in offspring in population I, although the effect attenuated and became non significant in males after adjusting for parental characteristics (adjusted hazard ratio (HR) = 1.80 (95%CI; 1.07, 3.03) in females, HR = 1.32 (95%CI; 0.93, 1.89) in males). In population II, no increase in ARD risk by grandparental social was evident. In both populations, males were at the highest ARD risk if both parents and grandparents belonged to disadvantaged social class (population I: HR = 1.82 (95%CI; 1.22-2.72); population II: HR = 1.68 (95%CI; 1.02-2.76)). CONCLUSIONS: Intergenerational social patterning of ARDs appears to be time contextual and gender-specific. The role of grandparental social class in developing ARDs in grandchildren seems to decline over time, while persistent grandparental-to-parental social disadvantage remains associated with higher ARD risk in males. When targeting higher risk groups, continuity of familial social disadvantage, particularly among males, should be considered. PMID- 29444096 TI - Invasive African clawed frogs in California: A reservoir for or predator against the chytrid fungus? AB - Amphibian species are experiencing population declines due to infection by the fungal pathogen, Batrachochytrium dendrobatidis (Bd). The African clawed frog (Xenopus laevis), an asymptomatic carrier of Bd, has been implicated in the spread of this pathogen through global trade and established invasive populations on several continents. However, research has not explored the relationships of both life stages of this amphibian with Bd. While the post-metamorphic individuals may act as a reservoir, spreading the infection to susceptible species, the filter-feeding larvae may consume the motile Bd zoospores from the water column, potentially reducing pathogen abundance and thus the likelihood of infection. We explore these contrasting processes by assessing Bd prevalence and infection intensities in field populations of post-metamorphic individuals, and performing laboratory experiments to determine if larval X. laevis preyed upon Bd zoospores. The water flea, Daphnia magna, was included in the Bd consumption trials to compare consumption rates and to explore whether intraguild predation between the larval X. laevis and Daphnia may occur, potentially interfering with control of Bd zoospores by Daphnia. Field surveys of three X. laevis populations in southern California, in which 70 post-metamorphic individuals were tested for Bd, found 10% infection prevalence. All infected individuals had very low infection loads (all Bd loads were below 5 zoospore equivalents). Laboratory experiments found that larval X. laevis consume Bd zoospores and therefore may reduce Bd abundance and transmission between amphibians. However, metamorphic and juvenile X. laevis exhibited intraguild predation by consuming Daphnia, which also prey upon Bd zoospores. The results suggest that X laevis is not a large reservoir for Bd and its larval stage may offer some reduction of Bd transmission through direct predation. PMID- 29444097 TI - The effects of intensified training on resting metabolic rate (RMR), body composition and performance in trained cyclists. AB - BACKGROUND: Recent research has demonstrated decreases in resting metabolic rate (RMR), body composition and performance following a period of intensified training in elite athletes, however the underlying mechanisms of change remain unclear. Therefore, the aim of the present study was to investigate how an intensified training period, designed to elicit overreaching, affects RMR, body composition, and performance in trained endurance athletes, and to elucidate underlying mechanisms. METHOD: Thirteen (n = 13) trained male cyclists completed a six-week training program consisting of a "Baseline" week (100% of regular training load), a "Build" week (~120% of Baseline load), two "Loading" weeks (~140, 150% of Baseline load, respectively) and two "Recovery" weeks (~80% of Baseline load). Training comprised of a combination of laboratory based interval sessions and on-road cycling. RMR, body composition, energy intake, appetite, heart rate variability (HRV), cycling performance, biochemical markers and mood responses were assessed at multiple time points throughout the six-week period. Data were analysed using a linear mixed modeling approach. RESULTS: The intensified training period elicited significant decreases in RMR (F(5,123.36) = 12.0947, p = <0.001), body mass (F(2,19.242) = 4.3362, p = 0.03), fat mass (F(2,20.35) = 56.2494, p = <0.001) and HRV (F(2,22.608) = 6.5212, p = 0.005); all of which improved following a period of recovery. A state of overreaching was induced, as identified by a reduction in anaerobic performance (F(5,121.87) = 8.2622, p = <0.001), aerobic performance (F(5,118.26) = 2.766, p = 0.02) and increase in total mood disturbance (F(5, 110.61) = 8.1159, p = <0.001). CONCLUSION: Intensified training periods elicit greater energy demands in trained cyclists, which, if not sufficiently compensated with increased dietary intake, appears to provoke a cascade of metabolic, hormonal and neural responses in an attempt to restore homeostasis and conserve energy. The proactive monitoring of energy intake, power output, mood state, body mass and HRV during intensified training periods may alleviate fatigue and attenuate the observed decrease in RMR, providing more optimal conditions for a positive training adaptation. PMID- 29444098 TI - Integrating nutrient bioavailability and co-production links when identifying sustainable diets: How low should we reduce meat consumption? AB - BACKGROUND: Reducing the consumption of meat and other animal-based products is widely advocated to improve the sustainability of diets in high-income countries. However, such reduction may impair nutritional adequacy, since the bioavailability of key nutrients is higher when they come from animal- vs plant based foods. Meat reduction may also affect the balance between foods co-produced within the same animal production system. OBJECTIVE: The objective was to assess the impact of introducing nutrient bioavailability and co-production links considerations on the dietary changes needed - especially regarding meat - to improve diet sustainability. METHODS: Diet optimization with linear and non linear programming was used to design, for each gender, three modeled diets departing the least from the mean observed French diet (OBS) while reducing by at least 30% the diet-related environmental impacts (greenhouse gas emissions, eutrophication, acidification): i) in the nutrition-environment (NE) model, the fulfillment of recommended dietary allowances for all nutrients was imposed; ii) in the NE-bioavailability (NEB) model, nutritional adequacy was further ensured by accounting for iron, zinc, protein and provitamin A bioavailability; iii) in the NEB-co-production (NEB-CP) model, two links between co-produced animal foods (milk-beef and blood sausage-pork) were additionally included into the models by proportionally co-constraining their respective quantities. The price and environmental impacts of individual foods were assumed to be constant. RESULTS: 'Fruit and vegetables' and 'Starches' quantities increased in all modeled diets compared to OBS. In parallel, total meat and ruminant meat quantities decreased. Starting from 110g/d women's OBS diet (168g/d for men), total meat quantity decreased by 78%, 67% and 32% for women (68%, 66% and 62% for men) in NE, NEB and NEB-CP diets, respectively. Starting from 36g/d women's OBS diet (54g/d for men), ruminant meat quantity dropped severely by 84% and 87% in NE and NEB diets for women (80% and 78% for men), whereas it only decreased by 27% in NEB-CP diets (38% for men). The share of energy and proteins of animal origin was similar for the 3 modeled diets (approximately 1/5 of total energy, and 1/2 of protein) and lower than in OBS diet (approximately 1/3 of total energy, and 2/3 of protein). CONCLUSIONS: Decreasing meat content was strictly needed to achieve more sustainable diets for French adults, but the reduction was less severe when nutrient bioavailability and co-production links were taken into account. PMID- 29444099 TI - Airway ciliary dysfunction and respiratory symptoms in patients with transposition of the great arteries. AB - BACKGROUND: Our prior work on congenital heart disease (CHD) with heterotaxy, a birth defect involving randomized left-right patterning, has shown an association of a high prevalence of airway ciliary dysfunction (CD; 18/43 or 42%) with increased respiratory symptoms. Furthermore, heterotaxy patients with ciliary dysfunction were shown to have more postsurgical pulmonary morbidities. These findings are likely a reflection of the common role of motile cilia in both airway clearance and left-right patterning. As CHD comprising transposition of the great arteries (TGA) is commonly thought to involve disturbance of left-right patterning, especially L-TGA with left-right ventricular inversion, we hypothesize CHD patients with transposition of great arteries (TGA) may have high prevalence of airway CD with increased respiratory symptoms. METHODS AND RESULTS: We recruited 75 CHD patients with isolated TGA, 28% L and 72% D-TGA. Patients were assessed using two tests typically used for evaluating airway ciliary dysfunction in patients with primary ciliary dyskinesia (PCD), a recessive sinopulmonary disease caused by respiratory ciliary dysfunction. This entailed the measurement of nasal nitric oxide (nNO), which is typically low with PCD. We also obtained nasal scrapes and conducted videomicroscopy to assess respiratory ciliary motion (CM). We observed low nNO in 29% of the patients, and abnormal CM in 57%, with 22% showing both low nNO and abnormal CM. No difference was observed for the prevalence of either low nNO or abnormal ciliary motion between patients with D vs. L-TGA. Respiratory symptoms were increased with abnormal CM, but not low nNO. Sequencing analysis showed no compound heterozygous or homozygous mutations in 39 genes known to cause PCD, nor in CFTR, gene causing cystic fibrosis. As both are recessive disorders, these results indicate TGA patients with ciliary dysfunction do not have PCD or cystic fibrosis (which can cause low nNO or abnormal ciliary motion). CONCLUSIONS: TGA patients have high prevalence of abnormal CM and low nNO, but ciliary dysfunction was not correlated with TGA type. Differing from PCD, respiratory symptoms were increased with abnormal CM, but not low nNO. Together with the negative findings from exome sequencing analysis, this would suggest TGA patients with ciliary dysfunction do not have PCD but nevertheless may suffer from milder airway clearance deficiency. Further studies are needed to investigate whether such ciliary dysfunction is associated with increased postsurgical complications as previously observed in CHD patients with heterotaxy. PMID- 29444100 TI - Super-ranging. A new ranging strategy in European badgers. AB - We monitored the ranging of a wild European badger (Meles meles) population over 7 years using GPS tracking collars. Badger range sizes varied seasonally and reached their maximum in June, July and August. We analysed the summer ranging behaviour, using 83 home range estimates from 48 individuals over 6974 collar nights. We found that while most adult badgers (males and females) remained within their own traditional social group boundaries, several male badgers (on average 22%) regularly ranged beyond these traditional boundaries. These adult males frequently ranged throughout two (or more) social group's traditional territories and had extremely large home ranges. We therefore refer to them as super-rangers. While ranging across traditional boundaries has been recorded over short periods of time for extraterritorial mating and foraging forays, or for pre dispersal exploration, the animals in this study maintained their super-ranges from 2 to 36 months. This study represents the first time such long-term extra territorial ranging has been described for European badgers. Holding a super range may confer an advantage in access to breeding females, but could also affect local interaction networks. In Ireland & the UK, badgers act as a wildlife reservoir for bovine tuberculosis (TB). Super-ranging may facilitate the spread of disease by increasing both direct interactions between conspecifics, particularly across social groups, and indirect interactions with cattle in their shared environment. Understanding super-ranging behaviour may both improve our understanding of tuberculosis epidemiology and inform future control strategies. PMID- 29444101 TI - Development and characterization of two cell lines from gills of Atlantic salmon. AB - Gill disease in Atlantic salmon, Salmo salar L., causes big losses in the salmon farming industry. Until now, tools to cultivate microorganisms causing gill disease and models to study the gill responses have been lacking. Here we describe the establishment and characterization of two cell lines from the gills of Atlantic salmon. Atlantic salmon gill cell ASG-10 consisted of cells staining for cytokeratin and e-cadherin and with desmosomes as seen by transmission electron microscopy suggesting the cells to be of epithelial origin. These structures were not seen in ASG-13. The cell lines have been maintained for almost 30 passages and both cell lines are fully susceptible to infection by infectious hematopoietic necrosis virus (IHNV), viral hemorrhagic septicemia virus (VHSV), infectious pancreatic necrosis virus (IPNV), Atlantic salmon reovirus TS (TSRV) and Pacific salmon paramyxovirus (PSPV). While infectious salmon anemia virus (ISAV) did not cause visible CPE, immunofluorescent staining revealed a sub-fraction of cells in both the ASG-10 and ASG-13 lines may be permissive to infection. ASG-10 is able to proliferate and migrate to close scratches in the monolayer within seven days in vitro contrary to ASG-13, which does not appear to do have the same proliferative and migratory ability. These cell lines will be useful in studies of gill diseases in Atlantic salmon and may represent an important contribution for alternatives to experimental animals and studies of epithelial-mesenchymal cell biology. PMID- 29444102 TI - Parallel behavioral and morphological divergence in fence lizards on two college campuses. AB - The spread of urban development has dramatically altered natural habitats, modifying community relationships, abiotic factors, and structural features. Animal populations living in these areas must perish, emigrate, or find ways to adjust to a suite of new selective pressures. Those that successfully inhabit the urban environment may make behavioral, physiological, and/or morphological adjustments that represent either evolutionary change and/or phenotypic plasticity. We tested for effects of urbanization on antipredator behavior and associated morphology across an urban-wild gradient in the western fence lizard (Sceloporus occidentalis) in two California counties, Santa Barbara and San Luis Obispo. We compared college campuses in both counties with adjacent rural habitats, conducting field trials that allowed us to characterize antipredator behavior in response to the acute stress of capture. We found notable divergence between campus and rural behavior, with campus lizards more frequently exhibiting diminished escape behavior, including tonic immobility, and lower sprint speeds. Furthermore, campus females had significantly shorter limbs, and while this did not explain variation in sprint speed, those with shorter limbs were more likely to show tonic immobility. We hypothesize that these parallel behavioral and morphological changes on both campuses reflect adjustment to a novel environment involving changes in predation and human presence. PMID- 29444103 TI - Macro and micro plastics sorb and desorb metals and act as a point source of trace metals to coastal ecosystems. AB - Nine urban intertidal regions in Burrard Inlet, Vancouver, British Columbia, Canada, were sampled for plastic debris. Debris included macro and micro plastics and originated from a wide diversity of uses ranging from personal hygiene to solar cells. Debris was characterized for its polymer through standard physiochemical characteristics, then subject to a weak acid extraction to remove the metals, zinc, copper, cadmium and lead from the polymer. Recently manufactured low density polyethylene (LDPE), nylon, polyethylene terephthalate (PET), polypropylene (PP), polystyrene (PS) and polyvinyl chloride (PVC) were subject to the same extraction. Data was statistically analyzed by appropriate parametric and non-parametric tests when needed with significance set at P < 0.05. Polymers identified in field samples in order of abundance were; PVC (39), LDPE (28), PS (18), polyethylene (PE, 9), PP (8), nylon (8), high density polyethylene (HDPE, 7), polycarbonate (PC, 6), PET (6), polyurethane (PUR, 3) and polyoxymethylene (POM, 2). PVC and LDPE accounted for 46% of all samples. Field samples of PVC, HDPE and LDPE had significantly greater amounts of acid extracted copper and HDPE, LDPE and PUR significantly greater amounts of acid extracted zinc. PVC and LDPE had significantly greater amounts of acid extracted cadmium and PVC tended to have greater levels of acid extracted lead, significantly so for HDPE. Five of the collected items demonstrated extreme levels of acid extracted metal; greatest concentrations were 188, 6667, 698,000 and 930 MUgg-1 of copper, zinc, lead and cadmium respectively recovered from an unidentified object comprised of PVC. Comparison of recently manufactured versus field samples indicated that recently manufactured samples had significantly greater amounts of acid extracted cadmium and zinc and field samples significantly greater amounts of acid extracted copper and lead which was primarily attributed to metal extracted from field samples of PVC. Plastic debris will affect metals within coastal ecosystems by; 1) providing a sorption site (copper and lead), notably for PVC 2) desorption from the plastic i.e., the "inherent" load (cadmium and zinc) and 3) serving as a point source of acute trace metal exposure to coastal ecosystems. All three mechanisms will put coastal ecosystems at risk to the toxic effects of these metals. PMID- 29444104 TI - ShDcR3 sensitizes TRAIL-resistant HCC cells by inducing caspase-dependent apoptosis while suppressing NF-kappaB dependent cFLIPL expression. AB - Evidence has shown that most hepatocellular carcinoma (HCC) cells are resistant to tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL)-mediated apoptosis. However, the molecular mechanisms underlying TRAIL-mediated apoptosis resistance are not well understood. In this study, we reported that downregulation of Decoy receptor 3 (DcR3) expression by lentiviral vectors carrying shRNA against DcR3 (LV-ShDcR3, shDcR3) in Huh7 both greatly enhanced TRAIL-mediated apoptosis and reduced cell proliferation capability. In addition, silencing DcR3 resulted in upregulation of the cell apoptotic regulators including Bid, caspase-3, and caspase-8. Caspase inhibitors inhibited shDcR3 mediated cell death, which indicated that downregulation of DcR3 expression in Huh7 cells increased TRAIL-induced caspase-dependent apoptotic cell death. Furthermore, although the knockdown of DcR3 altered the expression of some Bcl-2- and IAP-family proteins, this change was inhibited by pretreatment with a pancaspase inhibitor, which indicated the cytotoxic effect of shDcR3 was not due to the expression of these proteins. In contrast, shDcR3 significantly inhibited TRAIL-induced transcription factor nuclear kappaB (NF-kappaB) activation through the IkappaB kinase (IKK) pathway, as well as inhibited TRAIL-induced increases in FLICE-inhibitory protein long form (cFLIPL) expression at the transcriptional level. Silencing cFLIPL expression mimicked the cytotoxic effect of shDcR3 on TRAIL-mediated cell apoptosis. Moreover, overexpression of cFLIPL effectively prevented the increase in cell apoptosis in Huh7 cells co-treated with TRAIL and shDcR3. Taken together, our findings indicated that silencing DcR3 sensitizes TRAIL-mediated apoptosis in HCC cells by inhibiting NF-kappaB. PMID- 29444105 TI - Accuracy and precision of consumer-level activity monitors for stroke detection during wheelchair propulsion and arm ergometry. AB - The purpose of this study was to evaluate whether consumer-level activity trackers can estimate wheelchair strokes and arm ergometer revolutions. Thirty able-bodied participants wore three consumer-level activity trackers (Garmin VivoFit, FitBit Flex, and Jawbone UP24) on the wrist. Participants propelled a wheelchair at fixed frequencies (30, 45 and 60 strokes per minute (spm)) three minutes each and at pre-determined varied frequencies, (30-80 spm) for two minutes. Participants also freely wheeled through an obstacle course. 10 other participants performed arm-ergometry at 40, 60 and 80 revolutions per minute (rpm), for three minutes each. Mean percentage error (MPE(SD)) for 30 spm were >=46(26)% for all monitors, and declined to 3-6(2-7)% at 60 spm. For the obstacle course, MPE ranged from 12-17(7-13)% for all trackers. For arm-ergometry, MPE was at 1-96(0-37)% with the best measurement for the Fitbit at 60 and 80 rpm, and the Garmin at 80rpm, with MPE = 1(0-1)%. The consumer-level wrist-worn activity trackers we tested have higher accuracy/precision at higher movement frequencies but perform poorly at lower frequencies. PMID- 29444106 TI - Prevalence and risk factors of strabismus in children and adolescents in South Korea: Korea National Health and Nutrition Examination Survey, 2008-2011. AB - PURPOSE: To evaluate the prevalence and risk factors associated with horizontal strabismus in children and adolescents in South Korea. METHODS: A total of 5,935 children and adolescents 5-18 years of age who participated in the fourth and fifth Korean National Health and Nutrition Examination Survey (KNHANES IV-V) from July 2008 to December 2011 were evaluated and the prevalence of horizontal strabismus was estimated. Univariate and multivariate logistic regression analyses were conducted to determine the association between demographic, socioeconomic and clinical risk factors and clinically significant exodeviation (>=15 prism diopters [PD]) and esodeviation (>=10 PD). RESULTS: Among 5,935 eligible subjects, 84 subjects had clinically significant exodeviation and 13 had clinically significant esodeviation. The overall prevalence of clinically significant horizontal strabismus was 1.6% (95% confidence interval [CI], 1.2 2.1): 1.3% (95% CI, 1.0-1.7) for clinically significant exodeviation and 0.3% (95% CI, 0.1-0.6) for clinically significant esodeviation. Clinically significant exodeviation was associated with amblyopia (adjusted odds ratio [aOR], 6.45; 95% CI, 2.14-19.44), family history of strabismus (aOR, 4.91; 95% CI, 1.71-14.08) and astigmatism >=1.0 D (aOR, 1.84; 95% CI, 1.13-2.98). Clinically significant esodeviation was associated with hyperopia (aOR, 12.16; 95% CI, 1.31-113.04) and amblyopia (aOR, 4.70; 95% CI, 1.12-19.81). Other demographic, socioeconomic, and clinical variables were not associated with strabismus. CONCLUSION: This study provides data on the prevalence and independent risk factors for clinically significant exodeviation and esodeviation in a representative population of children and adolescents in South Korea. PMID- 29444107 TI - Shame in decision making under risk conditions: Understanding the effect of transparency. AB - The role played by the emotion of shame in the area of decision-making in situations of risk has hardly been studied. In this article, we show how the socio-moral emotions and the anticipated feeling of shame associated with different options can determine our decisions, even overriding the cognitive choice tendency proposed by the certainty effect. To do so, we carried out an experiment with university students as participants, dividing them into four experimental conditions. Our findings suggest that people avoid making unethical decisions, both when these decisions are made public to others and when they remain in the private sphere. This result seems to indicate that the main factor in not making unethical decisions is related to the need to avoid transgressing an internal moral standard of behavior, and that the role of transparency is less relevant than expected. However, we propose that, although the effect of transparency is limited in reducing unethical economic decisions, it should continue to be taken into account in theoretical models that address the reasons people behave unethically. PMID- 29444109 TI - Population structure of the NPGS Senegalese sorghum collection and its evaluation to identify new disease resistant genes. AB - Sorghum germplasm from West and Central Africa is cultivated in rainy and high humidity regions and is an important source of resistance genes to fungal diseases. Mold and anthracnose are two important biotic constraints to sorghum production in wet areas worldwide. Here, 158 National Plant Germplasm System (NPGS) accessions from Senegal were evaluated for agronomic traits, anthracnose, and grain mold resistance at two locations, and genetically characterized according to 20 simple sequence repeat markers. A total of 221 alleles were amplified with an average of 11 alleles per locus. Each accession had a unique genetic profile (i.e., no duplicates), and the average genetic distance between accessions was 0.42. Population structure and cluster analysis separated the collection into four populations with pairwise FST values >0.15. Three of the populations were composed of Guinea-race sorghum germplasm, and one included multiple races. Anthracnose resistant accessions were present at high frequency and evenly distributed among the three Guinea-race populations. Fourteen accessions showed resistance to grain mold, and eight were resistant to both diseases. These results indicated that the NPGS of Senegal is a genetically diverse collection with a high frequency of disease resistant accessions. Nevertheless, its population structure suggests the presence of few sources of resistance to both grain mold and anthracnose, which are fixed in the germplasm. The phenotypic and genotypic information for these accessions provides a valuable resource for its correct use to broaden the genetic base of breeding programs. PMID- 29444108 TI - Distribution of siderophore gene systems on a Vibrionaceae phylogeny: Database searches, phylogenetic analyses and evolutionary perspectives. AB - Siderophores are small molecules synthesized and secreted by bacteria and fungi to scavenge iron. Extracellular ferri-siderohores are recognized by cognate receptors on the cell surface for transport over membranes. Several siderophore systems from Vibrionaceae representatives are known and well understood, e.g., the molecular structure of the siderophore, the biosynthesis gene cluster and pathway, and the gene expression pattern. Less is known about how these systems are distributed among the ~140 Vibrionaceae species, and which evolutionary processes contributed to the present-day distribution. In this work, we compiled existing knowledge on siderophore biosynthesis systems and siderophore receptors from Vibrionaceae and used phylogenetic analyses to investigate their organization, distribution, origin and evolution. Through literature searches, we identified nine different siderophore biosynthesis systems and thirteen siderophore receptors in Vibrionaceae. Homologs were identified by BLAST searches, and the results were mapped onto a Vibrionaceae phylogeny. We identified 81 biosynthetic systems distributed in 45 Vibrionaceae species and 16 unclassified Vibrionaceae strains, and 409 receptors in 89 Vibrionaceae species and 49 unclassified Vibrionaceae strains. The majority of taxa are associated with at least one type of siderophore biosynthesis system, some (e.g., aerobactin and vibrioferrin) of which are widely distributed in the family, whereas others (i.e., bisucaberin and vibriobactin) are found in one lineage. Cognate receptors are found more widespread. Phylogenetic analysis of three siderophore systems (piscibactin, vibrioferrin and aerobactin) show that their present-day distribution can be explained by an old insertion into Vibrionaceae, followed mainly by stable vertical evolution and extensive loss, and some cases of horizontal gene transfers. The present work provides an up to date overview of the distribution of siderophore-based iron acquisition systems in Vibrionaceae, and presents phylogenetic analysis of these systems. Our results suggest that the present-day distribution is a result of several evolutionary processes, such as old and new gene acquisitions, gene loss, and both vertical and horizontal gene transfers. PMID- 29444110 TI - Leukemia inhibitory factor produced by fibroblasts within tumor stroma participates in invasion of oral squamous cell carcinoma. AB - The interaction between cancer cells and the cancer stroma plays a crucial role in tumor progression and metastasis in diverse malignancies, including oral cancer. However, the mechanism underlying this interaction remains incompletely elucidated. Here, to investigate the interaction between oral cancer cells and fibroblasts, which are major cellular components of the tumor stroma, we conducted an in vitro study by using human oral squamous cell carcinoma (OSCC) cell lines and normal human dermal fibroblasts (NHDFs). The results of transwell assays revealed that the migration and invasion of 2 OSCC cell lines, HO1-N-1 and HSC3, were markedly stimulated upon coculturing with NHDFs. To investigate the factors that promote tumor invasion, we isolated NHDFs from cocultures prepared with HO1-N-1 cells and performed microarray analysis. Among the various genes that were upregulated, we identified the gene encoding leukemia inhibitory factor (LIF), and we focused on LIF in further analyses. We confirmed that all OSCC derived conditioned media potently upregulated LIF expression in NHDFs, and the results of our transwell analysis demonstrated that NHDF-induced OSCC migration and invasion were inhibited by LIF-neutralizing antibodies. Furthermore, immunohistochemical analysis of patient samples revealed that in 44 out of 112 OSCC cases, LIF was expressed in the tumor stroma, particularly in cancer associated fibroblasts (CAFs), and, notably, clinicopathological analyses confirmed that LIF expression in CAFs was significantly correlated with increased depth of tumor invasion. Collectively, our results suggest that OSCC stimulates fibroblasts to produce LIF, which, in turn, participates in cancer-cell invasion. Our finding offers a potential therapeutic strategy targeting the cancer stroma for the treatment of OSCC patients. PMID- 29444111 TI - Genome-wide identification and role of MKK and MPK gene families in clubroot resistance of Brassica rapa. AB - Mitogen-activated protein kinase (MAPK or MPK) cascades play key roles in responses to various biotic stresses, as well as in plant growth and development. However, the responses of MPK and MPK kinase (MKK) in Chinese cabbage (Brassica rapa ssp. pekinensis) to Plasmodiophora brassicae, a causal agent of clubroot disease in Brassica crops, are still not clear. In the present study, a total of 11 B. rapa MKK (BraMKK) and 30 BraMPK genes were identified and unevenly distributed in 6 and 10 chromosomes, respectively. The synteny analysis indicated that these genes experienced whole-genome triplication and segmental and tandem duplication during or after the divergence of B. rapa, accompanied by the loss of three MKK and two MPK orthologs of Arabidopsis. The BraMKK and BraMPK genes were classified into four groups with similar intron/exon structures and conserved motifs in each group. A quantitative PCR analysis showed that the majority of BraMKK and BraMPK genes were natively expressed in roots, hypocotyls, and leaves, whereas 5 BraMKK and 16 BraMPK genes up-regulated in the roots upon P. brassicae infection. Additionally, these 5 BraMKK and 16 BraMPK genes exhibited a significantly different expression pattern between a pair of clubroot resistant/susceptible near-isogenic lines (NILs). Furthermore, the possible modules of MKK-MPK involved in B. rapa-P. brassicae interaction are also discussed. The present study will provide functional clues for further characterization of the MAPK cascades in B. rapa. PMID- 29444112 TI - Social network and dominance hierarchy analyses at Chimpanzee Sanctuary Northwest. AB - Different aspects of sociality bear considerable weight on the individual- and group-level welfare of captive nonhuman primates. Social Network Analysis (SNA) is a useful tool for gaining a holistic understanding of the dynamic social relationships of captive primate groups. Gaining a greater understanding of captive chimpanzees through investigations of centrality, preferred and avoided relationships, dominance hierarchy, and social network diagrams can be useful in advising current management practices in sanctuaries and other captive settings. In this study, we investigated the dyadic social relationships, group-level social networks, and dominance hierarchy of seven chimpanzees (Pan troglodytes) at Chimpanzee Sanctuary Northwest. We used focal-animal and instantaneous scan sampling to collect 106.75 total hours of associative, affiliative, and agonistic data from June to September 2016. We analyzed our data using SOCPROG to derive dominance hierarchies and network statistics, and we diagrammed the group's social networks in NetDraw. Three individuals were most central in the grooming network, while two others had little connection. Through agonistic networks, we found that group members reciprocally exhibited agonism, and the group's dominance hierarchy was statistically non-linear. One chimpanzee emerged as the most dominant through agonism but was least connected to other group members across affiliative networks. Our results indicate that the conventional methods used to calculate individuals' dominance rank may be inadequate to wholly depict a group's social relationships in captive sanctuary populations. Our results have an applied component that can aid sanctuary staff in a variety of ways to best ensure the improvement of group welfare. PMID- 29444113 TI - Effects of protein-protein interactions and ligand binding on the ion permeation in KCNQ1 potassium channel. AB - The voltage-gated KCNQ1 potassium ion channel interacts with the type I transmembrane protein minK (KCNE1) to generate the slow delayed rectifier (IKs) current in the heart. Mutations in these transmembrane proteins have been linked with several heart-related issues, including long QT syndromes (LQTS), congenital atrial fibrillation, and short QT syndrome. Off-target interactions of several drugs with that of KCNQ1/KCNE1 ion channel complex have been known to cause fatal cardiac irregularities. Thus, KCNQ1/KCNE1 remains an important avenue for drug design and discovery research. In this work, we present the structural and mechanistic details of potassium ion permeation through an open KCNQ1 structural model using the combined molecular dynamics and steered molecular dynamics simulations. We discuss the processes and key residues involved in the permeation of a potassium ion through the KCNQ1 ion channel, and how the ion permeation is affected by (i) the KCNQ1-KCNE1 interactions and (ii) the binding of chromanol 293B ligand and its derivatives into the complex. The results reveal that interactions between KCNQ1 with KCNE1 causes a pore constriction in the former, which in-turn forms small energetic barriers in the ion-permeation pathway. These findings correlate with the previous experimental reports that interactions of KCNE1 dramatically slows the activation of KCNQ1. Upon ligand-binding onto the complex, the energy-barriers along ion permeation path are more pronounced, as expected, therefore, requiring higher force in our steered-MD simulations. Nevertheless, pulling the ion when a weak blocker is bound to the channel does not necessitate high force in SMD. This indicates that our SMD simulations have been able to discern between strong and week blockers and reveal their influence on potassium ion permeation. The findings presented here will have some implications in understanding the potential off-target interactions of the drugs with the KCNQ1/KCNE1 channel that lead to cardiotoxic effects. PMID- 29444114 TI - Childhood obesity treatment; Effects on BMI SDS, body composition, and fasting plasma lipid concentrations. AB - OBJECTIVE: The body mass index (BMI) standard deviation score (SDS) may not adequately reflect changes in fat mass during childhood obesity treatment. This study aimed to investigate associations between BMI SDS, body composition, and fasting plasma lipid concentrations at baseline and during childhood obesity treatment. METHODS: 876 children and adolescents (498 girls) with overweight/obesity, median age 11.2 years (range 1.6-21.7), and median BMI SDS 2.8 (range 1.3-5.7) were enrolled in a multidisciplinary outpatient treatment program and followed for a median of 1.8 years (range 0.4-7.4). Height and weight, body composition measured by dual-energy X-ray absorptiometry, and fasting plasma lipid concentrations were assessed at baseline and at follow-up. Lipid concentrations (total cholesterol (TC), low-density lipoprotein (LDL), high density lipoprotein (HDL), non-HDL, and triglycerides (TG)) were available in 469 individuals (264 girls). Linear regressions were performed to investigate the associations between BMI SDS, body composition indices, and lipid concentrations. RESULTS: At baseline, BMI SDS was negatively associated with concentrations of HDL (p = 6.7*10-4) and positively with TG (p = 9.7*10-6). Reductions in BMI SDS were associated with reductions in total body fat percentage (p<2*10-16) and percent truncal body fat (p<2*10-16). Furthermore, reductions in BMI SDS were associated with improvements in concentrations of TC, LDL, HDL, non-HDL, LDL/HDL ratio, and TG (all p <0.0001). Changes in body fat percentage seemed to mediate the changes in plasma concentrations of TC, LDL, and non-HDL, but could not alone explain the changes in HDL, LDL/HDL-ratio or TG. Among 81 individuals with available lipid concentrations, who increased their BMI SDS, 61% improved their body composition, and 80% improved their lipid concentrations. CONCLUSION: Reductions in the degree of obesity during multidisciplinary childhood obesity treatment are accompanied by improvements in body composition and fasting plasma lipid concentrations. Even in individuals increasing their BMI SDS, body composition and lipid concentrations may improve. PMID- 29444115 TI - Forest bat population dynamics over 14 years at a climate refuge: Effects of timber harvesting and weather extremes. AB - Long-term data are needed to explore the interaction of weather extremes with habitat alteration; in particular, can 'refugia' buffer population dynamics against climate change and are they robust to disturbances such as timber harvesting. Because forest bats are good indicators of ecosystem health, we used 14 years (1999-2012) of mark-recapture data from a suite of small tree-hollow roosting bats to estimate survival, abundance and body condition in harvested and unharvested forest and over extreme El Nino and La Nina weather events in southeastern Australia. Trapping was replicated within an experimental forest, located in a climate refuge, with different timber harvesting treatments. We trapped foraging bats and banded 3043 with a 32% retrap rate. Mark-recapture analyses allowed for dependence of survival on time, species, sex, logging treatment and for transients. A large portion of the population remained resident, with a maximum time to recapture of nine years. The effect of logging history (unlogged vs 16-30 years post-logging regrowth) on apparent survival was minor and species specific, with no detectable effect for two species, a positive effect for one and negative for the other. There was no effect of logging history on abundance or body condition for any of these species. Apparent survival of residents was not strongly influenced by weather variation (except for the smallest species), unlike previous studies outside of refugia. Despite annual variation in abundance and body condition across the 14 years of the study, no relationship with extreme weather was evident. The location of our study area in a climate refuge potentially buffered bat population dynamics from extreme weather. These results support the value of climate refugia in mitigating climate change impacts, though the lack of an external control highlights the need for further studies on the functioning of climate refugia. Relatively stable population dynamics were not compromised by timber harvesting, suggesting ecologically sustainable harvesting may be compatible with climate refugia. PMID- 29444116 TI - Field evaluation of the safety, acceptability, and feasibility of early infant male circumcision using the AccuCirc device. AB - BACKGROUND: As countries scale up adult voluntary medical male circumcision (VMMC) for HIV prevention, they are looking ahead to long term sustainable strategies, including introduction of early infant male circumcision (EIMC). Although a number of devices for EIMC are prequalified by the World Health Organization, evaluation of additional devices can provide policy-makers and clinicians the information required to make informed decisions. We undertook a field evaluation of the safety and acceptability of the AccuCirc device in Kisumu County, Kenya. METHODS: Procedures were performed by four trained clinicians in two public facilities. Participants were recruited from surrounding public health facilities through informational talks at antenatal clinics, maternity wards, and maternal neonatal child health clinics. Healthy infants ages 0-60 days, with no penile abnormality, without a family history of bleeding disorder, with current weight-for-age within -2 Z-scores of WHO growth standards, and whose mother was at least 16 years of age were eligible for EIMC. The procedure was performed after administration of a penile dorsal nerve block using 2% lidocaine and administration of Vitamin K. The mother was given post-operative instructions on wound care and asked to remain in the clinic with the baby for an observational period of one hour, during which a face-to-face questionnaire was administered. RESULTS: Of 1259 babies screened, 704 were enrolled and circumcised. Median age of the infants was 16 days (IQR: 7-32.5) and of the mothers was 26 years (IQR: 22 30). Median time for the procedure was 19 minutes (IQR: 15-23). There were no serious adverse events (AE), and 20 (2.8%) moderate AEs, all of which were due to bleeding that required application of one to three sutures. There were 22 (3.8%) procedures in which the device did not fully incise the entire circumference of the foreskin and had to be completed using sterile scissors. 89.9% of mothers had knowledge of EIMC, but few (8.1%) had any knowledge of devices used for EIMC. Protection against HIV/AIDS was the most cited reason to circumcise a baby (65.3%), while the baby being ill (38.1%) and pain (34.4%) were the most cited barriers to uptake. 99% of mothers were "very satisfied" or "completely satisfied" with the procedure. CONCLUSIONS: This evaluation of the AccuCirc device is the largest to date and indicates that the device is safe and acceptable, achieving high levels of parental satisfaction. The AccuCirc device should be considered for WHO prequalification to increase options for safe and sustainable provision of EIMC. PMID- 29444118 TI - Demographic and genetic viability of a medium-sized ground-dwelling mammal in a fire prone, rapidly urbanizing landscape. AB - The rapid and large-scale urbanization of peri-urban areas poses major and complex challenges for wildlife conservation. We used population viability analysis (PVA) to evaluate the influence of urban encroachment, fire, and fauna crossing structures, with and without accounting for inbreeding effects, on the metapopulation viability of a medium-sized ground-dwelling mammal, the southern brown bandicoot (Isoodon obesulus), in the rapidly expanding city of Perth, Australia. We surveyed two metapopulations over one and a half years, and parameterized the PVA models using largely field-collected data. The models revealed that spatial isolation imposed by housing and road encroachment has major impacts on I. obesulus. Although the species is known to persist in small metapopulations at moderate levels of habitat fragmentation, the models indicate that these populations become highly vulnerable to demographic decline, genetic deterioration, and local extinction under increasing habitat connectivity loss. Isolated metapopulations were also predicted to be highly sensitive to fire, with large-scale fires having greater negative impacts on population abundance than small-scale ones. To reduce the risk of decline and local extirpation of I. obesulus and other small- to medium-sized ground-dwelling mammals in urbanizing, fire prone landscapes, we recommend that remnant vegetation and vegetated, structurally-complex corridors between habitat patches be retained. Well-designed road underpasses can be effective to connect habitat patches and reduce the probability of inbreeding and genetic differentiation; however, adjustment of fire management practices to limit the size of unplanned fires and ensure the retention of long unburnt vegetation will also be required to ensure persistence. Our study supports the evidence that in rapidly urbanizing landscapes, a pro active conservation approach is required that manages species at the metapopulation level and that prioritizes metapopulations and habitat with greater long-term probability of persistence and conservation capacity, respectively. This strategy may help us prevent future declines and local extirpations, and currently relatively common species from becoming rare. PMID- 29444117 TI - An ancestral TMEM16 homolog from Dictyostelium discoideum forms a scramblase. AB - TMEM16 proteins are a recently identified protein family comprising Ca2+ activated Cl- channels that generate outwardly rectifying ionic currents in response to intracellular Ca2+ elevations. Some TMEM16 family members, such as TMEM16F/ANO6 are also essential for Ca2+-dependent phospholipid scrambling. TMEM16-like genes are present in the genomes of most eukaryotic species, the function(s) of TMEM16 family members from evolutionary ancient eukaryotes is not completely clear. Here, we provide insight into the evolution of these TMEM16 proteins by similarity searches for ancestral sequences. All eukaryotic genomes contain TMEM16 homologs, but only vertebrates have the full repertoire of ten distinct subtypes. TMEM16 homologs studied so far belong to the opisthokont branch of the phylogenetic tree, which includes the animal and fungal kingdoms. An organism outside this group is Dictyostelium discoideum, a representative of the amoebozoa group that diverged from the metazoa before fungi. We here functionally investigated the TMEM16 family member from Dictyostelium discoideum. When recombinantly expressed in HEK293 cells, DdTMEM16 induces phospholipid scrambling. However, in several electrophysiological experiments we did not find evidence for a Ca2+-activated Cl- channel function of DdTMEM16. PMID- 29444119 TI - Accurate and fast path computation on large urban road networks: A general approach. AB - Accurate and fast path computation is essential for applications such as onboard navigation systems and traffic network routing. While a number of heuristic algorithms have been developed in the past few years for faster path queries, the accuracy of them are always far below satisfying. In this paper, we first develop an agglomerative graph partitioning method for generating high balanced traverse distance partitions, and we constitute a three-level graph model based on the graph partition scheme for structuring the urban road network. Then, we propose a new hierarchical path computation algorithm, which benefits from the hierarchical graph model and utilizes a region pruning strategy to significantly reduce the search space without compromising the accuracy. Finally, we present a detailed experimental evaluation on the real urban road network of New York City, and the experimental results demonstrate the effectiveness of the proposed approach to generate optimal fast paths and to facilitate real-time routing applications. PMID- 29444120 TI - Computer tomography-based body surface area evaluation for drug dosage: Quantitative radiology versus anthropomorphic evaluation. AB - OBJECTIVE: The measure of body surface area (BSA) is a standard for planning optimal dosing in oncology. This index is derived from a model having questionable performances. In this study, we proposed measurement of BSA from whole body CT images (iBSA). We tested the reliability of iBSA assessments and simulated the impact of our approach on patient chemotherapy dosage planning. METHODS: We first evaluated accuracy and precision of iBSA in measuring 14 phantom and 11 CT test-retest images.Secondly, we retrospectively analyzed 26 whole body PET-CT scans to evaluate inter-method variability between iBSA and the most used anthropomorphic models, notably the "Du Bois and Du Bois" model. Finally, we simulated the impact on chemotherapy dose planning of capecitabine based on iBSA. RESULTS: Precision and accuracy of iBSA measurement featured a standard deviation of 1.11% and a mean error of 1.53%. Inter-method variability between iBSA and "Du Bois and Du Bois" assessment featured a standard deviation of 4.11% leading to a reclassification rate of capecitabine of 32.5%. CONCLUSIONS: iBSA could help the oncologist in standardizing assessments for chemotherapy planning. iBSA could also be relevant for applications such as comprehensive body composition and provide a sensitive measurement for changes related to nutritional intake or other metabolism. PMID- 29444121 TI - No evidence of a causal relationship between hypothyroidism and glaucoma: A Danish nationwide register-based cohort study. AB - BACKGROUND: An interrelationship between hypothyroidism and glaucoma, due to a shared autoimmune background or based on deposition of mucopolysaccharides in the trabecular meshwork in the eye, has been suggested but is at present unsubstantiated. Therefore, our objective was to investigate, at a nationwide and population-based level, whether there is such an association. SUBJECTS AND METHODS: Observational cohort study using record-linkage data from nationwide Danish health registers. 121,799 individuals diagnosed with a first episode of hypothyroidism were identified and were matched with 4 non-hypothyroid controls according to age and sex. Prevalence of glaucoma was recorded and cases and controls were followed over a mean of 7.1 years (range 0-17). Logistic and Cox regression models were used to assess the risk of glaucoma before and after the diagnosis of hypothyroidism, respectively. RESULTS: Overall, we found a higher prevalence of glaucoma in subjects with hypothyroidism as compared to controls (4.6% vs. 4.3%, p < 0.001). Prior to the diagnosis of hypothyroidism, the odds ratio (OR) was significantly increased for glaucoma [1.09; 95% confidence interval (CI): 1.04-1.13]. Based on the Cox regression model, there was no increased risk of glaucoma after the diagnosis of hypothyroidism [hazard ratio (HR) 1.00; 95% CI: 0.96-1.06], and the HR decreased further after adjusting for pre-existing co-morbidity (0.88; 95% CI: 0.84-0.93). CONCLUSIONS: There was an increased risk of glaucoma before but not after the diagnosis of hypothyroidism, suggesting that screening for glaucoma in hypothyroid individuals is unwarranted. PMID- 29444122 TI - Latent tuberculosis infection in foreign-born communities: Import vs. transmission in The Netherlands derived through mathematical modelling. AB - While tuberculosis (TB) represents a significant disease burden worldwide, low incidence countries strive to reach the WHO target of pre-elimination by 2035. Screening for TB in immigrants is an important component of the strategy to reduce the TB burden in low-incidence settings. An important option is the screening and preventive treatment of latent TB infection (LTBI). Whether this policy is worthwhile depends on the extent of transmission within the country, and introduction of new cases through import. Mathematical transmission models of TB have been used to identify key parameters in the epidemiology of TB and estimate transmission rates. An important application has also been to investigate the consequences of policy scenarios. Here, we formulate a mathematical model for TB transmission within the Netherlands to estimate the size of the pool of latent infections, and to determine the share of importation either through immigration or travel- versus transmission within the Netherlands. We take into account importation of infections due to immigration, and travel to the country of origin, focusing on the three ethnicities most represented among foreign-born TB cases (after exclusion of those overrepresented among asylum seekers): Moroccans, Turkish and Indonesians. We fit a system of ordinary differential equations to the data from the Netherlands Tuberculosis Registry on (extra-)pulmonary TB cases from 1995-2013. We estimate that about 27% of Moroccans, 25% of Indonesians, and 16% of Turkish, are latently infected. Furthermore, we find that for all three foreign-born communities, immigration is the most important source of LTBI, but the extent of within-country transmission is much lower (about half) for the Turkish and Indonesian communities than for the Moroccan. This would imply that contact investigation would have a greater yield in the latter community than in the former. Travel remains a minor factor contributing LTBI, suggesting that targeting returning travelers might be less effective at preventing LTBI than immigrants upon entry in the country. PMID- 29444123 TI - Survival from alcoholic hepatitis has not improved over time. AB - PURPOSE/BACKGROUND: We aimed to describe changes in survival in alcoholic hepatitis (AH) over time by examining published data. METHODS: A systematic literature search of Ovid Embase and PubMed was undertaken using the MESH terms 'hepatitis, alcoholic' to identify randomised controlled trials (RCT) and observational studies (OS) in alcoholic hepatitis. Data were extracted from included studies regarding 28-day, 90-day, 180-day mortality, as well as biochemical and clinical data. RESULTS: After review of the literature search results, 77 studies published between 1971 and 2016 were analysed, which included data from a total of 8,184 patients. Overall mortality from AH was 26% at 28 days, 29% at 90 days and 44% at 180 days after admission. No changes in mortality over time were observed in univariable analysis at 28 days or 90 days after admission (Pearson correlation r -0.216, p = 0.098, and r 0.121 p = 0.503 respectively). A small but statistically significant increase in mortality was seen in 180-day mortality (r 0.461 p = 0.036). However, after meta-regression to adjust for other factors associated with mortality at each time point, no changes in mortality were seen. Sub-group analysis did not reveal any changes in mortality over time in different study types, or when only biopsy-proven or severe disease were considered. CONCLUSION: There has been no improvement in mortality from AH. This is not explained by changes in severity of disease. This emphasises the urgent need for effective treatments for this alcoholic hepatitis. PMID- 29444124 TI - Annual changes in rotavirus hospitalization rates before and after rotavirus vaccine implementation in the United States. AB - BACKGROUND: Hospitalizations for rotavirus and acute gastroenteritis (AGE) have declined in the US with rotavirus vaccination, though biennial peaks in incidence in children aged less than 5 years occur. This pattern may be explained by lower rotavirus vaccination coverage in US children (59% to 73% from 2010-2015), resulting in accumulation of susceptible children over two successive birth cohorts. METHODS: Retrospective cohort analysis of claims data of commercially insured US children aged <5 years. Age-stratified hospitalization rates for rotavirus and for AGE from the 2002-2015 rotavirus seasons were examined. Median age and rotavirus vaccination coverage for biennial rotavirus seasons during pre vaccine (2002-2005), early post-vaccine (2008-2011) and late post-vaccine (2012 2015) years. RESULTS: Age-stratified hospitalization rates decreased from pre vaccine to early post-vaccine and then to late post-vaccine years. The clearest biennial pattern in hospitalization rates is the early post-vaccine period, with higher rates in 2009 and 2011 than in 2008 and 2010. The pattern diminishes in the late post-vaccine period. For rotavirus hospitalizations, the median age and the difference in age between biennial seasons was highest during the early post vaccine period; these differences were not observed for AGE hospitalizations. There was no significant difference in vaccination coverage between biennial seasons. CONCLUSIONS: These observations provide conflicting evidence that incomplete vaccine coverage drove the biennial pattern in rotavirus hospitalizations that has emerged with rotavirus vaccination in the US. As this pattern is diminishing with higher vaccine coverage in recent years, further increases in vaccine coverage may reach a threshold that eliminates peak seasons in hospitalizations. PMID- 29444125 TI - Exploration of avocado by-products as natural sources of bioactive compounds. AB - This study aimed to evaluate the antioxidant, anti-inflammatory, and cytotoxic properties and phenolic composition of peel and seed of avocado varieties Hass and Fuerte using green solvents. Ethanol soluble compounds were identified in peel and seed of both varieties using HPLC-MS/MS and quantified using HPLC-DAD. Agro-industrial by-products of both varieties exhibited high radical scavenging activity against synthetic free radicals (DPPH and ABTS) and reactive oxygen species (peroxyl, superoxide, and hypochlorous acid) and high ability to reduce Fe3+ to Fe2+. The main compounds with significant contribution to the antioxidant activity determined by online HPLC-ABTS?+ analyses were procyanidin B2 and epicatechin in the peel and trans-5-O-caffeoyl-D-quinic acid, procyanidin B1, catechin, and epicatechin in the seed. Peel of Fuerte significantly suppressed TNF-alpha and nitric oxide (NO) release (459.3 pg/mL and 8.5 MUM, respectively), possibly because of the high phenolic content and antioxidant activity detected. Avocado agro-industrial by-products can be used for food and pharmaceutical purposes due to their antioxidant and anti-inflammatory properties. PMID- 29444126 TI - Applying the multi-threat framework of stereotype threat in the context of digital gaming. AB - Females often report experiencing stigmatisation pertaining to their competency in digital gaming communities. Employing the principles of the multi-threat framework of stereotype threat, the current research examined the impact of gender-related stereotypes on females' gaming performance and related self perceptions. In Experiment 1, 90 females were assigned to one of three conditions in which they were primed that their performance would be either diagnostic of their personal (self-as-target) or gender group's ability (group-as-target) or would be non-diagnostic of gaming ability (control). In Experiment 2, 90 females were primed that their performance would be judged by a group of other females (in-group source) or males (out-group source), or would be non-diagnostic of ability (control). Participants then completed a casual gaming task, as well as measures of competence beliefs, self-efficacy and self-esteem. Findings from Experiment 1 indicate that neither a self-as-target nor a group-as-target stereotype affected significantly gaming performance, or game-related self efficacy, self-esteem and competency beliefs. Findings from Experiment 2 reveal further that females' gaming performance and associated self-perceptions were not impacted significantly by an in-group or out-group source of stereotype threat. The discussion turns to potential explanations for these findings, proposing that females may not perceive negative gender-gaming stereotypes to be an accurate representation of their personal or social group's gaming ability. We also discuss the implications of the experimental design and difficulty, as well as the potential for domain identification to moderate performance outcomes under stereotype threat. PMID- 29444127 TI - Reducing vertices in property graphs. AB - Graph databases are constantly growing, and, at the same time, some of their data is the same or similar. Our experience with the management of the existing databases, especially the bigger ones, shows that certain vertices are particularly replicated there numerous times. Eliminating repetitive or even very similar data speeds up the access to database resources. We present a modification of this approach, where similarly we group together vertices of identical properties, but then additionally we join together groups of data that are located in distant parts of a graph. The second part of our approach is non trivial. We show that the search for a partition of a given graph where each member of the partition has only pairwise distant vertices is NP-hard. We indicate a group of heuristics that try to solve our difficult computational problems and then we apply them to check the the effectiveness of our approach. PMID- 29444128 TI - Molecular action of isoflavone genistein in the human epithelial cell line HaCaT. AB - Due to its strong proliferation-reducing effects on keratinocytes, and also anti inflammatory properties, the isoflavone genistein has already been proposed as a possible antipsoriatic compound. As there is still no detailed information on this topic, we examined the effects of genistein by using an in vitro model of both, normal and "psoriasis-like" keratinocytes at this stage of our work exhaustively testing the selected flavonoid in a mono-treated experimental design. Gene expression studies revealed transcriptional changes that confirms known disease-associated pathways and highlights many psoriasis-related genes. Our results suggested that aberrant expression of genes contributing to the progress of psoriasis could be improved by the action of genistein. Genistein prevented "cytokine mix" as well as TNF-alpha-induced NF-kappaB nuclear translocation, with no effect on the PI3K signaling cascade, indicating the luck of turning this pathway into NF-kappaB activation. It could have attenuated TNF alpha and LPS-induced inflammatory responses by suppressing ROS activation. Regardless of the type of keratinocyte stimulation used, reduction of cytokine IL 8, IL-20 and CCL2 production (both at RNA and protein level) following genistein treatment was visible. Because investigations of other groups supported our commentary on potential administration of genistein as a potential weapon in the armamentarium against psoriasis, it is believed that this paper should serve to encourage researchers to conduct further studies on this subject. PMID- 29444129 TI - Long-term habitat changes in a protected area: Implications for herpetofauna habitat management and restoration. AB - Point Pelee National Park, located at the southern-most tip of Canada's mainland, historically supported a large number of herpetofauna species; however, despite nearly a century of protection, six snake and five amphibian species have disappeared, and remaining species-at-risk populations are thought to be in decline. We hypothesized that long-term changes in availability and distribution of critical habitat types may have contributed to the disappearance of herpetofauna. To track habitat changes we used aerial image data spanning 85 years (1931-2015) and manually digitized and classified image data using a standardized framework. Change-detection analyses were used to evaluate the relative importance of proportionate loss and fragmentation of 17 habitat types. Marsh habitat diversity and aquatic connectivity has declined since 1931. The marsh matrix transitioned from a graminoid and forb shallow marsh interspersed with water to a cattail dominated marsh, altering critical breeding, foraging, and overwintering habitat. Reduced diversity of marsh habitats appears to be linked to the expansion of invasive Phragmites australis, which invaded prior to 2000. Loss of open habitats such as savanna and meadow has reduced availability of high quality thermoregulation habitat for reptiles. Restoration of the northwestern region and tip of Point Pelee National Park to a mixed landscape of shallow wetlands (cattail, graminoid, forb, open water) and eradication of dense Phragmites stands should improve habitat diversity. Our results suggest that long term landscape changes resulting from habitat succession and invasive species can negatively affect habitat suitability for herpetofauna and protection of land alone does not necessarily equate to protection of sensitive herpetofauna. PMID- 29444130 TI - "Are you gonna publish that?" Peer-reviewed publication outcomes of doctoral dissertations in psychology. AB - If a doctoral dissertation represents an original investigation that makes a contribution to one's field, then dissertation research could, and arguably should, be disseminated into the scientific literature. However, the extent and nature of dissertation publication remains largely unknown within psychology. The present study investigated the peer-reviewed publication outcomes of psychology dissertation research in the United States. Additionally, we examined publication lag, scientific impact, and variations across subfields. To investigate these questions, we first drew a stratified random cohort sample of 910 psychology Ph.D. dissertations from ProQuest Dissertations & Theses. Next, we conducted comprehensive literature searches for peer-reviewed journal articles derived from these dissertations published 0-7 years thereafter. Published dissertation articles were coded for their bibliographic details, citation rates, and journal impact metrics. Results showed that only one-quarter (25.6% [95% CI: 23.0, 28.4]) of dissertations were ultimately published in peer-reviewed journals, with significant variations across subfields (range: 10.1 to 59.4%). Rates of dissertation publication were lower in professional/applied subfields (e.g., clinical, counseling) compared to research/academic subfields (e.g., experimental, cognitive). When dissertations were published, however, they often appeared in influential journals (e.g., Thomson Reuters Impact Factor M = 2.84 [2.45, 3.23], 5-year Impact Factor M = 3.49 [3.07, 3.90]) and were cited numerous times (Web of Science citations per year M = 3.65 [2.88, 4.42]). Publication typically occurred within 2-3 years after the dissertation year. Overall, these results indicate that the large majority of Ph.D. dissertation research in psychology does not get disseminated into the peer-reviewed literature. The non publication of dissertation research appears to be a systemic problem affecting both research and training in psychology. Efforts to improve the quality and "publishability" of doctoral dissertation research could benefit psychological science on multiple fronts. PMID- 29444131 TI - Chromatin immunoprecipitation improvements for the processing of small frozen pieces of adipose tissue. AB - Chromatin immunoprecipitation (ChIP) has gained importance to identify links between the genome and the proteome. Adipose tissue has emerged as an active tissue, which secretes a wide range of molecules that have been related to metabolic and obesity-related disorders, such as diabetes, cardiovascular failure, metabolic syndrome, or cancer. In turn, epigenetics has raised the importance in discerning the possible relationship between metabolic disorders, lifestyle and environment. However, ChIP application in human adipose tissue is limited by several factors, such as sample size, frozen sample availability, high lipid content and cellular composition of the tissue. Here, we optimize the standard protocol of ChIP for small pieces of frozen human adipose tissue. In addition, we test ChIP for the histone mark H3K4m3, which is related to active promoters, and validate the performance of the ChIP by analyzing gene promoters for factors usually studied in adipose tissue using qPCR. Our improvements result in a higher performance in chromatin shearing and DNA recovery of adipocytes from the tissue, which may be useful for ChIP-qPCR or ChIP-seq analysis. PMID- 29444132 TI - A linear bi-level multi-objective program for optimal allocation of water resources. AB - This paper presents a simple bi-level multi-objective linear program (BLMOLP) with a hierarchical structure consisting of reservoir managers and several water use sectors under a multi-objective framework for the optimal allocation of limited water resources. Being the upper level decision makers (i.e., leader) in the hierarchy, the reservoir managers control the water allocation system and tend to create a balance among the competing water users thereby maximizing the total benefits to the society. On the other hand, the competing water use sectors, being the lower level decision makers (i.e., followers) in the hierarchy, aim only to maximize individual sectoral benefits. This multi objective bi-level optimization problem can be solved using the simultaneous compromise constraint (SICCON) technique which creates a compromise between upper and lower level decision makers (DMs), and transforms the multi-objective function into a single decision-making problem. The bi-level model developed in this study has been applied to the Swat River basin in Pakistan for the optimal allocation of water resources among competing water demand sectors and different scenarios have been developed. The application of the model in this study shows that the SICCON is a simple, applicable and feasible approach to solve the BLMOLP problem. Finally, the comparisons of the model results show that the optimization model is practical and efficient when it is applied to different conditions with priorities assigned to various water users. PMID- 29444133 TI - A long-term mechanistic computational model of physiological factors driving the onset of type 2 diabetes in an individual. AB - A computational model of the physiological mechanisms driving an individual's health towards onset of type 2 diabetes (T2D) is described, calibrated and validated using data from the Diabetes Prevention Program (DPP). The objective of this model is to quantify the factors that can be used for prevention of T2D. The model is energy and mass balanced and continuously simulates trajectories of variables including body weight components, fasting plasma glucose, insulin, and glycosylated hemoglobin among others on the time-scale of years. Modeled mechanisms include dynamic representations of intracellular insulin resistance, pancreatic beta-cell insulin production, oxidation of macronutrients, ketogenesis, effects of inflammation and reactive oxygen species, and conversion between stored and activated metabolic species, with body-weight connected to mass and energy balance. The model was calibrated to 331 placebo and 315 lifestyle-intervention DPP subjects, and one year forecasts of all individuals were generated. Predicted population mean errors were less than or of the same magnitude as clinical measurement error; mean forecast errors for weight and HbA1c were ~5%, supporting predictive capabilities of the model. Validation of lifestyle-intervention prediction is demonstrated by synthetically imposing diet and physical activity changes on DPP placebo subjects. Using subject level parameters, comparisons were made between exogenous and endogenous characteristics of subjects who progressed toward T2D (HbA1c > 6.5) over the course of the DPP study to those who did not. The comparison revealed significant differences in diets and pancreatic sensitivity to hyperglycemia but not in propensity to develop insulin resistance. A computational experiment was performed to explore relative contributions of exogenous versus endogenous factors between these groups. Translational uses to applications in public health and personalized healthcare are discussed. PMID- 29444134 TI - Effect of antibiotic withdrawal in feed on chicken gut microbial dynamics, immunity, growth performance and prevalence of foodborne pathogens. AB - Development of antibiotic resistance in foodborne pathogens, Salmonella spp. and Campylobacter, is a public health concern. Public demand to reduce the use of sub therapeutic antibiotic growth promoters (AGP) in poultry feeding has resulted in greater adoption of antibiotic-free poultry production systems. There is a need to understand the effects of AGP removal from poultry feed on gut microbiota and its impact on prevalence of foodborne pathogens. The effect of antibiotic withdrawal from poultry feed on gut microbial community, host performance and immunity, and prevalence of Salmonella and Campylobacter was evaluated. Birds were raised on three phase diets (starter [d0-22], grower [d23-35] and finisher [d36-42]) with and without bacitracin dimethyl salicyclate (BMD). At early growth stage, bird performance was improved (P <= 0.05) with BMD treatment, whereas performance was better (P <= 0.05) in control group (no BMD in the feed) at the time of commercial processing. Acetate and butyrate production was affected (P <= 0.05) by age, whereas propionate production was affected (P <= 0.05) by both the treatment and age. The bacterial communities in the cecum were more diverse (P <= 0.001) and rich compared to the ileal communities, and they shifted in parallel to one another as the chicks matured. Differences in diversity and species richness were not observed (P > 0.05) between the BMD-fed and control groups. Comparing all ages, treatments and diets, the composition of cecal and ileal bacterial communities was different (P <= 0.001). Inclusion of BMD in the feed did not affect the bacterial phyla. However, predictable shift in the ileal and cecal bacterial population at lower taxonomic level was observed in control vs BMD-fed group. Cytokines gene expression (IL-10, IL-4, IFN-gamma, beta-defensin, and TLR-4) was affected (P<= 0.05) in the BMD-fed group at early stages of growth. The prevalence of foodborne pathogens, Campylobacter spp. and Salmonella spp. showed higher abundance in the ilea of BMD-fed chicks compared to control group. Overall, this study provided insight of the impact of AGP supplementation in the feed on gut microbial modulations, bird performance, host immunity and pathogen prevalence. This information can assist in designing alternative strategies to replace antibiotics in modern poultry production and for food safety. PMID- 29444135 TI - Diagnosis of amphimeriasis by LAMPhimerus assay in human stool samples long-term storage onto filter paper. AB - Amphimeriasis, a fish-borne zoonotic disease caused by the liver fluke Amphimerus spp., has recently been reported as an emerging disease affecting an indigenous Ameridian group, the Chachi, living in Ecuador. The only method for diagnosing amphimeriasis was the microscopic detection of eggs from the parasite in patients' stool samples with very low sensitivity. Our group developed an ELISA technique for detection of anti-Amphimerus IgG in human sera and a molecular method based on LAMP technology (named LAMPhimerus) for specific and sensitive parasite DNA detection. The LAMPhimerus method showed to be much more sensitive than classical parasitological methods for amphimeriasis diagnosis using human stool samples for analysis. The objective of this work is to demonstrate the feasibility of using dried stool samples on filter paper as source of DNA in combination with the effectiveness of our previously designed LAMPhimerus assay for successfully Amphimerus sp. detection in clinical stool samples. A total of 102 untreated and undiluted stool samples collected from Chachi population were spread as thin layer onto common filter paper for easily transportation to our laboratory and stored at room temperature for one year until DNA extraction. When LAMPhimerus method was applied for Amphimerus sp. DNA detection, a higher number of positive results was detected (61/102; 59.80%) in comparison to parasitological methods (38/102; 37.25%), including 28/61 (45.90%) microscopy confirmed Amphimerus sp. infections. The diagnostic parameters for the sensitivity and specificity werecalculated for our LAMPhimerus assay, which were 79.17% and 65.98%, respectively. We demonstrate, for the first time, that common filter paper is useful for easy collection and long-term storage of human stool samples for later DNA extraction and molecular analysis of human-parasitic trematode eggs. This simple, economic and easily handling method combined with the specific and sensible LAMPhimerus assay has the potential to beused as an effective molecular large-scale screening test for amphimeriasis-endemic areas. PMID- 29444136 TI - LY2405319, an analog of fibroblast growth factor 21 ameliorates alpha-smooth muscle actin production through inhibition of the succinate-G-protein couple receptor 91 (GPR91) pathway in mice. AB - Fibroblast growth factor 21 (FGF21) is an important metabolic regulator expressed predominantly in the liver. In this study, we evaluated the role of LY2405319, an analogue of FGF21, in hepatic stellate cell (HSC) activation and in a methionine and choline-deficient (MCD)-diet induced mouse model of liver fibrosis. During liver injury, HSCs trans-differentiate into activated myofibroblasts which produce alpha-smooth muscle actin (alpha-SMA) and become a major cell type in hepatic fibrogenesis. Succinate and succinate receptor (GPR91) signaling has emerged as a regulator to promote alpha-SMA production in MCD diet- induced mice. Treatment with palmitate or MCD medium on LX-2 cells (HSCs) increased succinate concentration in the conditioned medium and cell lysate of LX-2 cells and increased production of GPR91 and alpha-SMA. However, LY2405319 administration ameliorates palmitate or MCD media-induced succinate production and decreases over-expression of GPR91 and alpha-SMA in LX2-cells. In an in vivo study, the MCD diet treatment caused increased steatohepatitis and liver fibrosis compared with the control diet in mice. Administration of LY2405319 improved steatohepatitis ameliorated GPR91 and alpha -SMA production in the liver, decreased succinate concentration in both liver and serum of MCD diet -induced mice. These results suggest that FGF21 reduces production of alpha-SMA by inhibiting the succinate GPR91 pathway. We conclude that FGF21 acts as an inhibitor of the succinate-GPR91 pathway to control liver fibrosis. This suggests that FGF21 has therapeutic potential for treating liver fibrogenesis. PMID- 29444137 TI - Anxiety is not enough to drive me away: A latent profile analysis on math anxiety and math motivation. AB - Mathematics anxiety (MA) and mathematics motivation (MM) are important multi dimensional non-cognitive factors in mathematics learning. While the negative relation between global MA and MM is well replicated, the relations between specific dimensions of MA and MM are largely unexplored. The present study utilized latent profile analysis to explore profiles of various aspects of MA (including learning MA and exam MA) and MM (including importance, self-perceived ability, and interest), to provide a more holistic understanding of the math specific emotion and motivation experiences. In a sample of 927 high school students (13-21 years old), we found 8 distinct profiles characterized by various combinations of dimensions of MA and MM, revealing the complexity in the math specific emotion-motivation relation beyond a single negative correlation. Further, these profiles differed on mathematics learning behaviors and mathematics achievement. For example, the highest achieving students reported modest exam MA and high MM, whereas the most engaged students were characterized by a combination of high exam MA and high MM. These results call for the need to move beyond linear relations among global constructs to address the complexity in the emotion-motivation-cognition interplay in mathematics learning, and highlight the importance of customized intervention for these heterogeneous groups. PMID- 29444138 TI - Voxel level quantification of [11C]CURB, a radioligand for Fatty Acid Amide Hydrolase, using high resolution positron emission tomography. AB - [11C]CURB is a novel irreversible radioligand for imaging fatty acid amide hydrolase in the human brain. In the present work, we validate an algorithm for generating parametric map images of [11C]CURB acquired with a high resolution research tomograph (HRRT) scanner. This algorithm applies the basis function method on an irreversible two-tissue compartment model (k4 = 0) with arterial input function, i.e., BAFPIC. Monte Carlo simulations are employed to assess bias and variability of the binding macroparameters (Ki and lambdak3) as a function of the voxel noise level and the range of basis functions. The results show that for a [11C]CURB time activity curve with noise levels corresponding to a voxel of an image acquired with the HRRT and reconstructed with the filtered back projection algorithm, the implementation of BAFPIC requires the use of a constant vascular fraction of tissue (5%) and a cutoff for slow frequencies (0.06 min-1). With these settings, BAFPIC maintains the probabilistic distributions of the binding macroparameters with approximately Gaussian shape and minimizes the bias and variability for large physiological ranges of the rate constants of [11C]CURB. BAFPIC reduces the variability of Ki to a third of that given by Patlak plot, the standard graphical method for irreversible radioligands. Application to real data demonstrated an excellent correlation between region of interest and BAFPIC parametric data and agreed with the simulations results. Therefore, BAFPIC with a constant vascular fraction can be used to generate parametric maps of [11C]CURB images acquired with an HRRT provided that the limits of the basis functions are carefully selected. PMID- 29444139 TI - Post-discharge body weight and neurodevelopmental outcomes among very low birth weight infants in Taiwan: A nationwide cohort study. AB - BACKGROUND: Premature infants are at high risk for developmental delay and cognitive dysfunction. Besides medical conditions, growth restriction is regarded as an important risk factor for cognitive and neurodevelopmental dysfunction throughout childhood and adolescence and even into adulthood. In this study, we analyzed the relationship between post-discharge body weight and psychomotor development using a nationwide dataset. MATERIALS AND METHODS: This was a nationwide cohort study conducted in Taiwan. Total of 1791 premature infants born between 2007 and 2011 with a birth weight of less than 1500 g were enrolled into this multi-center study. The data were obtained from the Taiwan Premature Infant Developmental Collaborative Study Group. The growth and neurodevelopmental evaluations were performed at corrected ages of 6, 12 and 24 months. Post discharge failure to thrive was defined as a body weight below the 3rd percentile of the standard growth curve for Taiwanese children by the corrected age. RESULTS: The prevalence of failure to thrive was 15.8%, 16.9%, and 12.0% at corrected ages of 6, 12, and 24 months, respectively. At corrected ages of 24 months, 12.9% had low Mental Developmental Index (MDI) scores (MDI<70), 17.8% had low Psychomotor Developmental Index (PDI) scores (PDI<70), 12.7% had cerebral palsy, and 29.5% had neurodevelopmental impairment. Post-discharge failure to thrive was significantly associated with poor neurodevelopmental outcomes. After controlling for potential confounding factors (small for gestational age, extra uterine growth retardation at discharge, cerebral palsy, gender, mild intraventricular hemorrhage, persistent pulmonary hypertension of newborn, respiratory distress syndrome, chronic lung disease, hemodynamic significant patent ductus arteriosus, necrotizing enterocolitis, surfactant use and indomethacin use), post-discharge failure to thrive remained a risk factor. CONCLUSION: This observational study observed the association between lower body weight at corrected age of 6, 12, and 24 months and poor neurodevelopmental outcomes among VLBW premature infants. There are many adverse factors which can influence the neurodevelopment in NICU care. More studies are needed to elucidate the causal relationship. PMID- 29444140 TI - Getting to FP2020: Harnessing the private sector to increase modern contraceptive access and choice in Ethiopia, Nigeria, and DRC. AB - BACKGROUND: An estimated 214 million women have unmet need for family planning in developing regions. Improved utilization of the private sector is key to achieving universal access to a range of safe and effective modern contraceptive methods stipulated by FP2020 and SDG commitments. Until now, a lack of market data has limited understanding of the private sector's role in increasing contraceptive coverage and choice. METHODS: In 2015, the FPwatch Project conducted representative outlet surveys in Ethiopia, Nigeria, and DRC using a full census approach in selected administrative areas. Every public and private sector outlet with the potential to sell or distribute modern contraceptives was approached. In outlets with modern contraceptives, product audits and provider interviews assessed contraceptive market composition, availability, and price. FINDINGS: Excluding general retailers, 96% of potential outlets in Ethiopia, 55% in Nigeria, and 41% in DRC had modern contraceptive methods available. In Ethiopia, 41% of modern contraceptive stocking outlets were in the private sector compared with approximately 80% in Nigeria and DRC where drug shops were dominant. Ninety-five percent of private sector outlets in Ethiopia had modern contraceptive methods available; 37% had three or more methods. In Nigeria and DRC, only 54% and 42% of private sector outlets stocked modern contraceptives with 5% and 4% stocking three or more methods, respectively. High prices in Nigeria and DRC create barriers to consumer access and choice. DISCUSSION: There is a missed opportunity to provide modern contraception through the private sector, particularly drug shops. Subsidies and interventions, like social marketing and social franchising, could leverage the private sector's role in increasing access to a range of contraceptives. Achieving global FP2020 commitments depends on the expansion of national contraceptive policies that promote greater partnership and cooperation with the private sector and improvement of decisions around funding streams of countries with large populations and high unmet need like Ethiopia, Nigeria, and DRC. PMID- 29444141 TI - The 3-min all-out test is valid for determining critical power but not anaerobic work capacity in tethered running. AB - The purpose of the study was to investigate if the 3-min all-out test (3MT) is valid for obtaining critical power intensity (CP) and the amount of work that can be performed above CP (W') on non-motorized treadmills in tethered running. Eight physically active individuals (24 +/- 3 years; 78.3 +/- 8.7 kg; 179 +/- 5 cm; 9.0 +/- 2.5% body fat) performed four different efforts at constant intensity to exhaustion in order to determine CP and W'. The mechanical power values obtained were subsequently plotted with their corresponding time to exhaustion (limit time) for application of three mathematical models: power hyperbolic versus time limit (Hyp), linear power versus 1/time (P vs 1/t) and linear work versus time limit (? vs t). The 3MT test was carried out on the last day to determine end power (EP) and anaerobic capacity (WEP) using this methodology. EP value of 181.7 +/- 52 was similar (p = 0.486) to 178.2 +/- 61 (CP Hyp), 191.4 +/- 55 (? vs t) and 188.3 +/- 55 (P vs 1/t). WEP value of 17.9 +/- 4.8 was not similar (p = 0.000) to 50.2 +/- 15.3 (CP Hyp), 44.8 +/- 8.7 (? vs t) and 45.5 +/- 8.4 (P vs 1/t). Positive results (r = 0.78-0.98 and ICC = 0.88-0.99) of Pearson correlation and intraclass correlation (ICC-absolute agreement) were found for aerobic applications of conventional CP and 3MT. For anaerobic data, only the three models of conventional CP were correlated (r = 0.76-0.93); however, W' from the three models was not correlated with WEP (r = 0.37-0.52). The results of this study suggest that 3MT in tethered running on non-motorized treadmills is a valid test for estimating CP aerobic parameters in a single day of application but not anaerobic parameters of W'. PMID- 29444142 TI - Roots of symptom-free leguminous cover crop and living mulch species harbor diverse Fusarium communities that show highly variable aggressiveness on pea (Pisum sativum). AB - Leguminous cover crop and living mulch species show not only great potential for providing multiple beneficial services to agro-ecosystems, but may also present pathological risks for other crops in rotations through shared pathogens, especially those of the genus Fusarium. Disease severity on roots of subterranean clover, white clover, winter and summer vetch grown as cover crop and living mulch species across five European sites as well as the frequency, distribution and aggressiveness to pea of Fusarium spp. recovered from the roots were assessed in 2013 and 2014. Disease symptoms were very low at all sites. Nevertheless, out of 1480 asymptomatic roots, 670 isolates of 14 Fusarium spp. were recovered. The most frequently isolated species in both years from all hosts were F. oxysporum and F. avenaceum accounting for 69% of total isolation percentage. They were common at the Swiss, Italian and German sites, whereas at the Swedish site F. oxysporum dominated and F. avenaceum occurred only rarely. The agressiveness and effect on pea biomass were tested in greenhouse assays for 72 isolates of six Fusarium species. Isolates of F. avenaceum caused severe root rot symptoms with mean severity index (DI) of 82 and 74% mean biomass reduction compared to the non inoculated control. Fusarium oxysporum and F. solani isolates were higly variable in agressiveness and their impact on pea biomass. DI varied between 15 and 50 and biomass changes relative to the non-inoculated control -40% to +10%. Isolates of F. tricinctum, F. acuminatum and F. equiseti were non to weakly agressive often enhancing pea biomass. This study shows that some of the major pea pathogens are characterized by high ecological plasticity and have the ability to endophytically colonize the hosts studied that thus may serve as inoculum reservoir for susceptible main legume grain crops such as pea. PMID- 29444144 TI - Improved GGIW-PHD filter for maneuvering non-ellipsoidal extended targets or group targets tracking based on sub-random matrices. AB - For non-ellipsoidal extended targets and group targets tracking (NETT and NGTT), using an ellipsoid to approximate the target extension may not be accurate enough because of the lack of shape and orientation information. In consideration of this, we model a non-ellipsoidal extended target or target group as a combination of multiple ellipsoidal sub-objects, each represented by a random matrix. Based on these models, an improved gamma Gaussian inverse Wishart probability hypothesis density (GGIW-PHD) filter is proposed to estimate the measurement rates, kinematic states, and extension states of the sub-objects for each extended target or target group. For maneuvering NETT and NGTT, a multi-model (MM) approach based GGIW-PHD (MM-GGIW-PHD) filter is proposed. The common and the individual dynamics of the sub-objects belonging to the same extended target or target group are described by means of the combination between the overall maneuver model and the sub-object models. For the merging of updating components, an improved merging criterion and a new merging method are derived. A specific implementation of prediction partition with pseudo-likelihood method is presented. Two scenarios for non-maneuvering and maneuvering NETT and NGTT are simulated. The results demonstrate the effectiveness of the proposed algorithms. PMID- 29444143 TI - Australian shellfish ecosystems: Past distribution, current status and future direction. AB - We review the status of marine shellfish ecosystems formed primarily by bivalves in Australia, including: identifying ecosystem-forming species, assessing their historical and current extent, causes for decline and past and present management. Fourteen species of bivalves were identified as developing complex, three-dimensional reef or bed ecosystems in intertidal and subtidal areas across tropical, subtropical and temperate Australia. A dramatic decline in the extent and condition of Australia's two most common shellfish ecosystems, developed by Saccostrea glomerata and Ostrea angasi oysters, occurred during the mid-1800s to early 1900s in concurrence with extensive harvesting for food and lime production, ecosystem modification, disease outbreaks and a decline in water quality. Out of 118 historical locations containing O. angasi-developed ecosystems, only one location still contains the ecosystem whilst only six locations are known to still contain S. glomerata-developed ecosystems out of 60 historical locations. Ecosystems developed by the introduced oyster Crasostrea gigas are likely to be increasing in extent, whilst data on the remaining 11 ecosystem-forming species are limited, preventing a detailed assessment of their current ecosystem-forming status. Our analysis identifies that current knowledge on extent, physical characteristics, biodiversity and ecosystem services of Australian shellfish ecosystems is extremely limited. Despite the limited information on shellfish ecosystems, a number of restoration projects have recently been initiated across Australia and we propose a number of existing government policies and conservation mechanisms, if enacted, would readily serve to support the future conservation and recovery of Australia's shellfish ecosystems.

AB - Stable single-alpha helices (SAH-domains) function as rigid connectors and constant force springs between structural domains, and can provide contact surfaces for protein-protein and protein-RNA interactions. SAH-domains mainly consist of charged amino acids and are monomeric and stable in polar solutions, characteristics which distinguish them from coiled-coil domains and intrinsically disordered regions. Although the number of reported SAH-domains is steadily increasing, genome-wide analyses of SAH-domains in eukaryotic genomes are still missing. Here, we present Waggawagga-CLI, a command-line tool for predicting and analysing SAH-domains in protein sequence datasets. Using Waggawagga-CLI we predicted SAH-domains in 24 datasets from eukaryotes across the tree of life. SAH domains were predicted in 0.5 to 3.5% of the protein-coding content per species. SAH-domains are particularly present in longer proteins supporting their function as structural building block in multi-domain proteins. In human, SAH-domains are mainly used as alternative building blocks not being present in all transcripts of a gene. Gene ontology analysis showed that yeast proteins with SAH-domains are particular enriched in macromolecular complex subunit organization, cellular component biogenesis and RNA metabolic processes, and that they have a strong nuclear and ribonucleoprotein complex localization and function in ribosome and nucleic acid binding. Human proteins with SAH-domains have roles in all types of RNA processing and cytoskeleton organization, and are predicted to function in RNA binding, protein binding involved in cell and cell-cell adhesion, and cytoskeletal protein binding. Waggawagga-CLI allows the user to adjust the stabilizing and destabilizing contribution of amino acid interactions in i,i+3 and i,i+4 spacings, and provides extensive flexibility for user-designed analyses.

AB - This study aimed to monitor the course of liver regeneration by multiparametric magnetic-resonance imaging (MRI) after partial liver resection characterizing Small-for-Size Syndrome (SFSS), which frequently leads to fatal post-hepatectomy liver failure (PLF). Twenty-two C57BL/6 mice underwent either conventional 70% partial hepatectomy (cPH), extended 86% partial hepatectomy (ePH) or SHAM operation. Subsequent MRI scans on days 0, 1, 2, 3, 5 and 7 in a 4.7T MR Scanner quantified longitudinal and transverse relaxation times, apparent diffusion coefficient (ADC) and the magnetization-transfer ratio (MTR) of the regenerating liver parenchyma. Histological examination was performed by hematoxylin-eosin staining. After hepatectomy, an increase of T1 time was detected being larger for ePH on day 1: 18% for cPH vs. 40% for ePH and on day 2: 24% for cPH vs. 49% for ePH. An increase in T2 time, again greater in ePH was most pronounced on day 5: 21% for cPH vs. 41% for ePH. ADC and MTR showed a decrease on day 1: 21% for ePH vs. 13% for cPH for ADC, 15% for ePH vs. 11% for cPH for MTR. Subsequently, all MR parameters converged towards initial values in surviving animals. Dying PLF animals exhibited the strongest increase of T1 relaxation time and most prominent decreases of ADC and MTR. The retrieved MRI biomarkers indicate SFSS and potentially developing PLF at an early stage, likely reflecting cellular hypertrophy with extended water content and concomitantly diluted cellular components as features of liver regeneration, appearing more intense in ePH as compared to cPH.

By changing an email announcement sent out to employees in 2014 (n > 30,000), the following interventions are tested: incentives, attention to the negative impacts of not get vaccinated, and showing a map to the vaccination centers at the end of the email announcement. Only the map condition helped increase influenza vaccination rates. The use of low-cost interventions can improve influenza vaccination rates though not all interventions work as well as others in the field. In particular, while including maps helped increase vaccination rates, other factors such as negative impact reminders and incentives, which previous studies have found to be successful in the laboratory, did not. PMID- 29444149 TI - Sociability between invasive guppies and native topminnows. AB - The role of interspecific social interactions during species invasions may be more decisive than previously thought. Research has revealed that invasive fish improve their foraging success by shoaling with native Mexican species, and potentially increase the chances of invasion success. However, do native individuals tend to associate with invaders as well? We tested the hypothesis that the twoline skiffia (Neotoca bilineata) and the Lerma livebearer (Poeciliopsis infans), both native endemic Mexican topminnows, will associate with guppies, a notorious invasive species present in Mexico. Our investigation shows that guppies, twoline skiffias and Lerma livebearers have a mutual tendency to associate with each other. Although there is a marked tendency to shoal with heterospecifics in this system, shoaling partners do not necessarily benefit equally from the association. Further research on invasive-native social interactions is needed to promote our understanding of potential facilitation by natives. PMID- 29444148 TI - Development of a recombinase polymerase amplification assay for rapid detection of Francisella noatunensis subsp. orientalis. AB - Francisella noatunensis subsp. orientalis (Fno) is the causative agent of piscine francisellosis in warm water fish including tilapia. The disease induces chronic granulomatous inflammation with high morbidity and can result in high mortality. Early and accurate detection of Fno is crucial to set appropriate outbreak control measures in tilapia farms. Laboratory detection of Fno mainly depends on bacterial culture and molecular techniques. Recombinase polymerase amplification (RPA) is a novel isothermal technology that has been widely used for the molecular diagnosis of various infectious diseases. In this study, a recombinase polymerase amplification (RPA) assay for rapid detection of Fno was developed and validated. The RPA reaction was performed at a constant temperature of 42 degrees C for 20 min. The RPA assay was performed using a quantitative plasmid standard containing a unique Fno gene sequence. Validation of the assay was performed not only by using DNA from Fno, closely related Francisella species and other common bacterial pathogens in tilapia farms, but also by screening 78 Nile tilapia and 5 water samples. All results were compared with those obtained by previously established real-time qPCR. The developed RPA showed high specificity in detection of Fno with no cross-detection of either the closely related Francisella spp. or the other tested bacteria. The Fno-RPA performance was highly comparable to the published qPCR with detection limits at 15 and 11 DNA molecules detected, respectively. The RPA gave quicker results in approximately 6 min in contrast to the qPCR that needed about 90 min to reach the same detection limit, taking only 2.7-3 min to determine Fno in clinical samples. Moreover, RPA was more tolerant to reaction inhibitors than qPCR when tested with field samples. The fast reaction, simplicity, cost-effectiveness, sensitivity and specificity make the RPA an attractive diagnostic tool that will contribute to controlling the infection through prompt on-site detection of Fno. PMID- 29444150 TI - Probiotic and anti-inflammatory potential of Lactobacillus rhamnosus 4B15 and Lactobacillus gasseri 4M13 isolated from infant feces. AB - A total of 22 Lactobacillus strains, which were isolated from infant feces were evaluated for their probiotic potential along with resistance to low pH and bile salts. Eight isolates (L. reuteri 3M02 and 3M03, L. gasseri 4M13, 4R22, 5R01, 5R02, and 5R13, and L. rhamnosus 4B15) with high tolerance to acid and bile salts, and ability to adhere to the intestine were screened from 22 strains. Further, functional properties of 8 Lactobacillus strains, such as anti oxidation, inhibition of alpha-glucosidase activity, cholesterol-lowering, and anti-inflammation were evaluated. The properties were strain-specific. Particularly, two strains of L. rhamnosus, 4B15 (4B15) and L. gasseri 4M13 (4M13) showed considerably higher anti-oxidation, inhibition of alpha-glucosidase activity, and cholesterol-lowering, and greater inhibition of nitric oxide production than other strains. Moreover, the two selected strains substantially inhibited the release of inflammatory mediators such as TNF-alpha, IL-6, IL 1beta, and IL-10 stimulated the treatment of RAW 264.7 macrophages with LPS. In addition, whole genome sequencing and comparative genomic analysis of 4B15 and 4M13 indicated them as novel genomic strains. These results suggested that 4B15 and 4M13 showed the highest probiotic potential and have an impact on immune health by modulating pro-inflammatory cytokines. PMID- 29444151 TI - Predicting 1-year mortality after hospitalization for community-acquired pneumonia. AB - BACKGROUND: Community-acquired pneumonia (CAP) is a major public health problem with high short- and long-term mortality. The main aim of this study was to develop and validate a specific prognostic index for one-year mortality in patients admitted for CAP. METHODS: This was an observational, prospective study of adults aged >=18 years admitted to Galdakao-Usansolo Hospital (Bizkaia, Spain) from January 2001 to July 2009 with a diagnosis of CAP surviving the first 15 days. The entire cohort was divided into two parts, in order to develop a one year mortality predictive model in the derivation cohort, before validation using the second cohort. RESULTS: A total of 2351 patients were included and divided into a derivation and a validation cohort. After deaths within 15 days were excluded, one-year mortality was 10.63%. A predictive model was created in order to predict one-year mortality, with a weighted score that included: aged over 80 years (4 points), congestive heart failure (2 points), dementia (6 points), respiratory rate >=30 breaths per minute (2 points) and blood urea nitrogen >30 mg/dL (3 points) as predictors of higher risk with C-index of 0.76. This new model showed better predictive ability than current risk scores, PSI, CURB65 and SCAP with C-index of 0.73, 0.69 and 0.70, respectively. CONCLUSIONS: An easy-to use score, called the one-year CAPSI, may be useful for identifying patients with a high probability of dying after an episode of CAP. PMID- 29444153 TI - Head movements and postures as pain behavior. AB - Pain assessment can benefit from observation of pain behaviors, such as guarding or facial expression, and observational pain scales are widely used in clinical practice with nonverbal patients. However, little is known about head movements and postures in the context of pain. In this regard, we analyze videos of three publically available datasets. The BioVid dataset was recorded with healthy participants subjected to painful heat stimuli. In the BP4D dataset, healthy participants performed a cold-pressor test and several other tasks (meant to elicit emotion). The UNBC dataset videos show shoulder pain patients during range of-motion tests to their affected and unaffected limbs. In all videos, participants were sitting in an upright position. We studied head movements and postures that occurred during the painful and control trials by measuring head orientation from video over time, followed by analyzing posture and movement summary statistics and occurrence frequencies of typical postures and movements. We found significant differences between pain and control trials with analyses of variance and binomial tests. In BioVid and BP4D, pain was accompanied by head movements and postures that tend to be oriented downwards or towards the pain site. We also found differences in movement range and speed in all three datasets. The results suggest that head movements and postures should be considered for pain assessment and research. As additional pain indicators, they possibly might improve pain management whenever behavior is assessed, especially in nonverbal individuals such as infants or patients with dementia. However, in advance more research is needed to identify specific head movements and postures in pain patients. PMID- 29444152 TI - The interaction between cannabis use and the Val158Met polymorphism of the COMT gene in psychosis: A transdiagnostic meta - analysis. AB - BACKGROUND: Neither environmental nor genetic factors are sufficient to predict the transdiagnostic expression of psychosis. Therefore, analysis of gene environment interactions may be productive. OBJECTIVE: A meta-analysis was performed using papers investigating the interaction between cannabis use and catechol-O-methyl transferase (COMT) polymorphism Val158Met (COMTVal158Met). DATA SOURCES: PubMed, Embase, PsychInfo. STUDY ELIGIBILITY CRITERIA: All observational studies assessing the interaction between COMTVal158Met and cannabis with any psychosis or psychotic symptoms measure as an outcome. STUDY APPRAISAL AND SYNTHESIS METHODS: A meta-analysis was performed using the Meta-analysis of Observational Studies in Epidemiology guidelines and forest plots were generated. Thirteen articles met the selection criteria: 7 clinical studies using a case only design, 3 clinical studies with a dichotomous outcome, and 3 studies analysing a continuous outcome of psychotic symptoms below the threshold of psychotic disorder. The three study types were analysed separately. Validity of the included studies was assessed using "A Cochrane Risk of Bias Assessment Tool: for Non-Randomized Studies of Interventions". RESULTS: For case-only studies, a significant interaction was found between cannabis use and COMTVal158Met, with an OR of 1.45 (95% Confidence Interval = 1.05-2.00; Met/Met as the risk genotype). However, there was no evidence for interaction in either the studies including dichotomous outcomes (B = -0.51, 95% Confidence Interval -1.72, 0.70) or the studies including continuous outcomes (B = -0.04 95% Confidence Interval -0.16 0.08). LIMITATION: A substantial part of the included studies used the case-only design, which has lower validity and tends to overestimate true effects. CONCLUSION: The interaction term between cannabis use and COMTVal158Met was only statistically significant in the case-only studies, but not in studies using other clinical or non-clinical psychosis outcomes. Future additional high quality studies might change current perspectives, yet currently evidence for the interaction remains unconvincing. PMID- 29444154 TI - Associations between owner personality and psychological status and the prevalence of canine behavior problems. AB - Behavioral problems are a major source of poor welfare and premature mortality in companion dogs. Previous studies have demonstrated associations between owners' personality and psychological status and the prevalence and/or severity of their dogs' behavior problems. However, the mechanisms responsible for these associations are currently unknown. Other studies have detected links between the tendency of dogs to display behavior problems and their owners' use of aversive or confrontational training methods. This raises the possibility that the effects of owner personality and psychological status on dog behavior are mediated via their influence on the owner's choice of training methods. We investigated this hypothesis in a self-selected, convenience sample of 1564 current dog owners using an online battery of questionnaires designed to measure, respectively, owner personality, depression, emotion regulation, use of aversive/confrontational training methods, and owner-reported dog behavior. Multivariate linear and logistic regression analyses identified modest, positive associations between owners' use of aversive/confrontational training methods and the prevalence/severity of the following dog behavior problems: owner-directed aggression, stranger-directed aggression, separation problems, chasing, persistent barking, and house-soiling (urination and defecation when left alone). The regression models also detected modest associations between owners' low scores on four of the 'Big Five' personality dimensions (Agreeableness, Emotional Stability, Extraversion & Conscientiousness) and their dogs' tendency to display higher rates of owner-directed aggression, stranger-directed fear, and/or urination when left alone. The study found only weak evidence to support the hypothesis that these relationships between owner personality and dog behavior were mediated via the owners' use of punitive training methods, but it did detect a more than five-fold increase in the use of aversive/confrontational training techniques among men with moderate depression. Further research is needed to clarify the causal relationship between owner personality and psychological status and the behavioral problems of companion dogs. PMID- 29444155 TI - Conjunctival melanocytic naevus: Diagnostic value of anterior segment optical coherence tomography and ultrasound biomicroscopy. AB - PURPOSE: Conjunctival naevi are the most frequently diagnosed primary melanocytic lesions of the conjunctiva. The clinical manifestations are greatly variable which may result in diagnostic difficulties and differential diagnostic confusions. Therefore aims of the present study were: 1) to assess the morphologic features of conjunctival naevi; 2) to delineate the anterior segment optical coherence tomography (AS-OCT) characteristics of these lesions; 3) to compare AS-OCT and ultrasound biomicroscopy (UBM) as diagnostic tools in these alterations and 4) to correlate histological results with the AS-OCT pictures in case of surgically excised naevi. METHODS: All lesions were photo-documented. AS OCT and UBM (over the age of 18 years) were performed. Surgically excised lesions were admitted to histological examinations. RESULTS: In our series of 57 conjunctival naevi, 54.4% were highly pigmented, 15.8% proved to be amelanotic. AS-OCT could detect intralesional cysts in 61.4% of the naevi, while slit-lamp and UBM proved to be less sensitive (40.3% vs. 28.5%). UBM could visualize the posterior margins of all naevi, while AS-OCT proved to be less sensitive with the detection of 89.4% of posterior naevus margins. Thickness of the conjunctival epithelial layer could be measured with AS-OCT in case of subepithelial naevi, while no distinct epithelial layer could be detected in compound and junctional naevi. CONCLUSIONS: Superiority of AS-OCT over UBM was demonstrated in visualizing internal structures of conjunctival naevi. UBM proved to be a better tool in highly pigmented and remarkably elevated naevi. Correlation was found between the histological type of the naevus and the thickness of the epithelial layer covering the lesion. PMID- 29444156 TI - Protein S-glutathionylation lowers superoxide/hydrogen peroxide release from skeletal muscle mitochondria through modification of complex I and inhibition of pyruvate uptake. AB - Protein S-glutathionylation is a reversible redox modification that regulates mitochondrial metabolism and reactive oxygen species (ROS) production in liver and cardiac tissue. However, whether or not it controls ROS release from skeletal muscle mitochondria has not been explored. In the present study, we examined if chemically-induced protein S-glutathionylation could alter superoxide (O2? )/hydrogen peroxide (H2O2) release from isolated muscle mitochondria. Disulfiram, a powerful chemical S-glutathionylation catalyst, was used to S-glutathionylate mitochondrial proteins and ascertain if it can alter ROS production. It was found that O2?-/H2O2 release rates from permeabilized muscle mitochondria decreased with increasing doses of disulfiram (100-500 MUM). This effect was highest in mitochondria oxidizing succinate or palmitoyl-carnitine, where a ~80-90% decrease in the rate of ROS release was observed. Similar effects were detected in intact mitochondria respiring under state 4 conditions. Incubation of disulfiram-treated mitochondria with DTT (2 mM) restored ROS release confirming that these effects were associated with protein S-glutathionylation. Disulfiram treatment also inhibited phosphorylating and proton leak-dependent respiration. Radiolabelled substrate uptake experiments demonstrated that disulfiram inhibited pyruvate import but had no effect on carnitine uptake. Immunoblot analysis of complex I revealed that it contained several protein S-glutathionylation targets including NDUSF1, a subunit required for NADH oxidation. Taken together, these results demonstrate that O2?-/H2O2 release from muscle mitochondria can be altered by protein S-glutathionylation. We attribute these changes to the protein S glutathionylation complex I and inhibition of mitochondrial pyruvate carrier. PMID- 29444158 TI - Practicable methods for histological section thickness measurement in quantitative stereological analyses. AB - The accuracy of quantitative stereological analysis tools such as the (physical) disector method substantially depends on the precise determination of the thickness of the analyzed histological sections. One conventional method for measurement of histological section thickness is to re-embed the section of interest vertically to its original section plane. The section thickness is then measured in a subsequently prepared histological section of this orthogonally re embedded sample. However, the orthogonal re-embedding (ORE) technique is quite work- and time-intensive and may produce inaccurate section thickness measurement values due to unintentional slightly oblique (non-orthogonal) positioning of the re-embedded sample-section. Here, an improved ORE method is presented, allowing for determination of the factual section plane angle of the re-embedded section, and correction of measured section thickness values for oblique (non-orthogonal) sectioning. For this, the analyzed section is mounted flat on a foil of known thickness (calibration foil) and both the section and the calibration foil are then vertically (re-)embedded. The section angle of the re-embedded section is then calculated from the deviation of the measured section thickness of the calibration foil and its factual thickness, using basic geometry. To find a practicable, fast, and accurate alternative to ORE, the suitability of spectral reflectance (SR) measurement for determination of plastic section thicknesses was evaluated. Using a commercially available optical reflectometer (F20, Filmetrics(r), USA), the thicknesses of 0.5 MUm thick semi-thin Epon (glycid ether)-sections and of 1-3 MUm thick plastic sections (glycolmethacrylate/ methylmethacrylate, GMA/MMA), as regularly used in physical disector analyses, could precisely be measured within few seconds. Compared to the measured section thicknesses determined by ORE, SR measures displayed less than 1% deviation. Our results prove the applicability of SR to efficiently provide accurate section thickness measurements as a prerequisite for reliable estimates of dependent quantitative stereological parameters. PMID- 29444157 TI - Does radiation therapy increase gadolinium accumulation in the brain?: Quantitative analysis of T1 shortening using R1 relaxometry in glioblastoma multiforme patients. AB - OBJECTIVE: This study evaluated the possibility of accelerated gadolinium accumulation in irradiated brain parenchyma where the blood-brain barrier was weakened. METHODS: From January 2010 to June 2015, 44 patients with supratentorial glioblastoma were retrospectively identified who underwent pre- and post-radiation brain MR imaging, including R1 mapping. The mean dose of administered gadobutrol (Gadovist, Bayer, Germany) was 5.1 vials. Regions of interest (ROIs) were drawn around tumors that were located within 50-100% iso dose lines of maximum radiation dose. ROIs were also drawn at globus pallidus, thalamus, and cerebral white matter. Averages of R1 values (unit: s-1) before and after radiation and those of R1 ratio (post-radiation R1 / pre-radiation R1) were compared by t-test or rank sum test as appropriate. Multiple linear regression analysis was performed to evaluate independent association factors for R1 value increase at irradiated parenchyma. RESULTS: The mean R1 values in peri-tumoral areas were significantly increased after radiotherapy (0.7901+/-0.0977 [mean+/ SD] vs. 0.8146+/-0.1064; P <.01). The mean R1 ratio of high radiation dose areas was significantly higher than that of low dose areas (1.0055+/-0.0654 vs. 0.9882+/-0.0642; P <.01). The mean R1 ratio was lower in those who underwent hypofractionated radiotherapy (mean dose, 45.0 Gy) than those who underwent routine radiotherapy (mean dose, 61.1 Gy) (0.9913+/-0.0740 vs. 1.0463+/-0.0633; P = .08). Multiple linear regression analysis revealed that only radiotherapy type was significantly associated with increased R1 (P = .02) around tumors. CONCLUSIONS: Radiotherapy can induce R1 value increase in the brain parenchyma, which might suggest accelerated gadolinium accumulation due to damage to the blood-brain barrier. PMID- 29444159 TI - Antitumor effects of metformin via indirect inhibition of protein phosphatase 2A in patients with endometrial cancer. AB - OBJECTIVE: Metformin, an antidiabetic drug, inhibits the endometrial cancer cell growth in vivo by improving the insulin resistance; however, its mechanism of action is not completely understood. Protein phosphatase 2A (PP2A) is a serine/threonine phosphatase associated with insulin resistance and type 2 diabetes, and its inhibition restores the insulin resistance. This study investigated the antitumor effect of metformin on endometrial cancer with a focus on PP2A. METHODS: Metformin (1,500-2,250 mg/day) was preoperatively administered to patients with endometrial cancer for 4 to 6 weeks. Expression of the PP2A regulatory subunits, 4 (PPP2R4) and B (PP2A-B), was evaluated using real-time polymerase chain reaction (RT-PCR) and immunohistochemistry (IHC) using paired specimens obtained before and after metformin treatment. The effect of PPP2R4 inhibition with small interfering RNA was evaluated in the endometrial cancer cell lines HEC265 and HEC1B. P values of < .05 were considered statistically significant. RESULTS: Preoperative metformin treatment significantly reduced the expression of PP2A-B, as determined using IHC, and the mRNA expression of PPP2R4, as determined using RT-PCR, in the patients with endometrial cancer. However, metformin could not directly alter the PPP2R4 mRNA levels in the endometrial cancer cell lines in vitro. PPP2R4 knockdown reduced the proliferation and induced the apoptosis by activating caspases 3/7 in HEC265 and HEC1B cells. CONCLUSIONS: Downregulation of the PP2A-B subunit, including PPP2R4, is an important indirect target of metformin. Inhibition of PP2A may be an option for the treatment of endometrial cancer patients with insulin resistance. TRIAL REGISTRATION: This trial is registered with UMIN-CTR (number UMIN000004852). PMID- 29444160 TI - Towards the use of similarity distances to music genre classification: A comparative study. AB - Music genre classification is a challenging research concept, for which open questions remain regarding classification approach, music piece representation, distances between/within genres, and so on. In this paper an investigation on the classification of generated music pieces is performed, based on the idea that grouping close related known pieces in different sets -or clusters- and then generating in an automatic way a new song which is somehow "inspired" in each set, the new song would be more likely to be classified as belonging to the set which inspired it, based on the same distance used to separate the clusters. Different music pieces representations and distances among pieces are used; obtained results are promising, and indicate the appropriateness of the used approach even in a such a subjective area as music genre classification is. PMID- 29444161 TI - A 3D anatomical atlas of appendage musculature in the chelicerate arthropod Limulus polyphemus. AB - Limulus polyphemus, an archetypal chelicerate taxon, has interested both biological and paleontological researchers due to its unique suite of anatomical features and as a useful modern analogue for fossil arthropod groups. To assist the study and documentation of this iconic taxon, we present a 3D atlas on the appendage musculature, with specific focus on the muscles of the cephalothoracic appendages. As L. polyphemus appendage musculature has been the focus of extensive study, depicting the muscles in 3D will facilitate a more complete understanding thereof for future researchers. A large museum specimen was CT scanned to illustrate the major exoskeletal features of L. polyphemus. Micro-CT scans of iodine-stained appendages from fresh, non-museum specimens were digitally dissected to interactively depict appendage sections and muscles. This study has revealed the presence of two new muscles: one within the pushing leg, located dorsally relative to all other patella muscles, and the other within the male pedipalp, located in the modified tibiotarsus. This atlas increases accessibility to important internal and external morphological features of L. polyphemus and reduces the need for destructive fresh tissue dissection of specimens. Scanning, digitally dissecting, and documenting taxa in 3D is a pivotal step towards creating permanent digital records of life on Earth. PMID- 29444162 TI - Low serum levels of High-Density Lipoprotein cholesterol (HDL-c) as an indicator for the development of severe postpartum depressive symptoms. AB - Postpartum depression (PPD) is a psychiatric complication of childbirth affecting 10-20% of new mothers and has negative impact on both mother and infant. Serum lipid levels have been related to depressive disorders, but very limited literatures are available regarding the lipid levels in women with postpartum depression. The present study is aimed to examine the association of serum lipids with the development of postpartum depressive symptoms. This is a cross sectional study conducted at a tertiary care hospital in South India. Women who came for postpartum check-up at 6th week post-delivery were screened for PPD (September 2014-October 2015). Women with depressive symptoms were assessed using EPDS (Edinburgh Postnatal Depression Scale). The study involved 186 cases and 250 controls matched for age and BMI. Serum levels of lipid parameters were estimated through spectrophotometry and the atherogenic indices were calculated in all the subjects. Low serum levels of Total Cholesterol (TC) and High Density Lipoprotein cholesterol (HDL-c) were significantly low in PPD women with severe depressive symptoms. The study recorded a significant negative correlation between HDL-c and the EPDS score in PPD women (r = -0.140, p = 0.05). Interestingly, the study also observed a significant negative correlation between Body Mass Index (BMI) and EPDS scores in case group (r = -0.146, p = 0.047), whereas a positive correlation between the same in controls (r = 0.187, p = 0.004). Our study demonstrated that low levels of serum HDL-c is correlated with the development of severe depressive symptoms in postpartum women. Study highlights the role of lipids in the development of postpartum depressive symptoms. PMID- 29444163 TI - The effect of "NutramilTM Complex," food for special medical purpose, on breast and prostate carcinoma cells. AB - NutramilTM Complex is a multicomponent food product that meets the requirements of a food for special medical purpose. As a complete, high-energy diet it consists of properly balanced nutrients, vitamins and minerals. The aim of this study was to assess the effect of NutramilTM Complex on breast and prostate carcinoma cells. Our results showed that NutramilTM Complex reduced the viability and proliferation of breast and prostate cancer cells and that this process was associated with the induction of apoptosis via activation of caspase signalling. Data showed elevated levels of p53 tumour suppressor, up-regulation of p38 MAPK and SAPK / JNK proteins and downregulation of anti-apoptotic ERK1/2, AKT1 and HSP27. Treatment with NutramilTM Complex also affected the expression of the BCL2 family genes. Results also showed down-regulation of anti-apoptotic BCL-2 and up regulation of pro-apoptotic members such as BAX, BAD, BID. In addition, we also observed regulation of many other genes, including Ikappabetaalpha, Chk1 and Chk2, associated with apoptotic events. Taken together, our results suggest activation of the mitochondrial apoptotic pathway as most likely mechanism of anti-carcinogenic activity of NutramilTM Complex. PMID- 29444165 TI - Frequency, trends, and antecedents of severe maternal depression after three million U.S. births. AB - BACKGROUND: Postpartum depression carries adverse consequences for mothers and children, so widespread screening during primary care visits is recommended. However, the rates, timing, and factors associated with significant depressive episodes are incompletely understood. METHODS AND FINDINGS: We examined the Healthcare Cost and Utilization Project (HCUP) State Inpatient, Emergency Department, and Ambulatory Surgery and Services Databases from California (2005 2011) and Florida (2005-2012). Within 203 million records, we identified 3,213,111 births and all mothers who had hospital encounters for severe depression within 40 weeks following delivery. We identified 15,806 episodes of postpartum depression after 11,103 deliveries among 10,883 unique women, and calculated an overall rate of 36.7 depression- associated hospital visits per 10,000 deliveries. Upward trends were observed in both states, with combined five year increases of 34%. First depressive events were most common within 30 days of delivery, but continued for the entire observation period. About half (1,661/3,325) of PPD first episodes occurred within 34 days of delivery, 70% (2,329/3,325) by the end of the second month, and 87% (2,893/3,325) before four months of the delivery. Women with private insurance were less likely to have hospital encounters for depression than women with public insurance and women with depression were much more likely to have had some kind of hospital encounter at some time during their pregnancies. Rates of depression increased with the number of prenatal hospital encounters in a "dose-dependent" fashion: the rate of depression was 17.2/10,000 for women with no prenatal hospital visits, doubling for women with at least one encounter (34.9/10,000), and increasing 7-fold to 126/10,000 for women with three or more encounters during their pregnancies. CONCLUSIONS: Our findings suggest that (1) hospital encounters for post-partum depression are increasing, (2) screening should begin very early and continue for the first year after delivery, and (3) added attention should be given to women who had hospital encounters during their pregnancies.

AB - BACKGROUND: Early information on treatment response of HCC to local ablative therapy is crucial. Elastography as a non-invasive method has recently been shown to play a potential role in distinguishing between benign and malignant liver lesions. Elastography of hepatocellular carcinoma (HCC) in early response to local ablative therapy has not been studied to date. METHODS: We prospectively included a cohort of 14 patients with diagnosis of HCC who were treated with local ablative therapy (transarterial chemoembolization, TACE and/or radiofrequency ablation, RFA). We used 2D shear-wave elastography (RT 2D-SWE) to examine stiffness of HCC lesion before and 3, 30 and 90 days after local ablative therapy. Contrast-enhanced imaging after 90 days was performed to evaluate treatment response. Primary endpoint was stiffness of HCC in response to local ablative therapy. Secondary end point was tumor recurrence. RESULTS: Stiffness of HCC nodules and liver showed no significant difference prior to local ablative therapy. As early as three days after treatment, stiffness of responding HCC was significantly higher compared to non-responding. Higher stiffness before treatment was significantly associated with tumor recurrence. CONCLUSION: Nodule stiffness in general and RT 2D-SWE in particular could provide a useful tool for early prediction of HCC response to local ablative therapy. PMID- 29444166 TI - Fairness informs social decision making in infancy. AB - The ability to reason about fairness plays a defining role in the development of morality. Thus, researchers have long been interested in understanding when and how a sensitivity to fairness first develops. Here, we examined infants' ability to use fairness information in selecting social partners. Using a novel experimental paradigm that combined pre-recorded stimuli with an active behavioral measure, we tested whether infants preferred to socially engage with an individual they had previously seen behave fairly or unfairly. After viewing an individual distribute goods to third parties either equally (i.e., 3:3 distribution) or unequally (i.e., 5:1 distribution), both 13- and 17-month-old infants selectively chose to engage in a social interaction with (i.e., take a toy from) an individual who distributed resources equally. The use of a novel paradigm to assess infants' fairness preferences demonstrates that infants' previously established fairness preferences extend across different, more demanding paradigms, and may therefore be more enduring in nature. Together, these findings provide new insights into the nature of infants' fairness representations, and fill in key gaps in the developmental timeline of infants' ability to use fairness information in their consideration of potential social partners. In sum, these findings build on previous research by demonstrating that infants not only hold an expectation that resources should be distributed fairly, they also preferentially interact with those who have previously done so. The early-emerging ability to both reason about and use fairness information may play an influential role in the development of complex prosocial behaviors related to morality more broadly.

AB - BACKGROUND: In August 2011, Ontario, Canada introduced a rotavirus immunization program using RotarixTM vaccine. No assessments of rotavirus vaccine coverage have been previously conducted in Ontario. METHODS: We assessed vaccine coverage (series initiation and completion) and factors associated with uptake using the Electronic Medical Record Administrative data Linked Database (EMRALD), a collection of family physician electronic medical records (EMR) linked to health administrative data. Series initiation (1 dose) and series completion (2 doses) before and after the program's introduction were calculated. To identify factors associated with series initiation and completion, adjusted odds ratios (aOR) and 95% confidence intervals (95%CI) were calculated using logistic regression. RESULTS: A total of 12,525 children were included. Series completion increased each year of the program (73%, 79% and 84%, respectively). Factors associated with series initiation included high continuity of care (aOR = 2.15; 95%CI, 1.61 2.87), maternal influenza vaccination (aOR = 1.55; 95%CI,1.24-1.93), maternal immmigration to Canada in the last five years (aOR = 1.47; 95% CI, 1.05-2.04), and having no siblings (aOR = 1.62; 95%CI,1.30-2.03). Relative to the first program year, infants were more likely to initiate the series in the second year (aOR = 1.71; 95% CI 1.39-2.10) and third year (aOR = 2.02; 95% CI 1.56-2.61) of the program. Infants receiving care from physicians with large practices were less likely to initiate the series (aOR 0.91; 95%CI, 0.88-0.94, per 100 patients rostered) and less likely to complete the series (aOR 0.94; 95%CI, 0.91-0.97, per 100 patients rostered). Additional associations were identified for series completion. CONCLUSIONS: Family physician delivery achieved moderately high coverage in the program's first three years. This assessment demonstrates the usefulness of EMR data for evaluating vaccine coverage. Important insights into factors associated with initiation or completion (i.e. high continuity of care, smaller roster sizes, rural practice location) suggest areas for research and potential program supports. PMID- 29444168 TI - Identifying genetic risk loci for diabetic complications and showing evidence for heterogeneity of type 1 diabetes based on complications risk. AB - There is a growing body of evidence suggesting that type 1 diabetes (T1D) is a genetically heterogeneous disease. However, the extent of this heterogeneity, and what observations may distinguish different forms, is unclear. One indicator may be T1D-related microvascular complications (MVCs), which are familial, but occur in some families, and not others. We tested the hypothesis that T1D plus MVC is genetically distinct from T1D without MCV. We studied 415 families (2,462 individuals, 896 with T1D) using genome-wide linkage analysis, comparing families with and without MVC. We also tested for interaction between identified loci and alleles at the HLA-DRB1 locus. We found significant linkage scores at 1p36.12, 1q32.1, 8q21.3, 12p11.21 and 22q11.21. In all regions except 1p36.12, linkage scores differed between MVC-based phenotype groups, suggesting that families with MVCs express different genetic influences than those without. Our linkage results also suggested gene-gene interaction between the above putative loci and the HLA region; HLA-based strata produced significantly increased linkage scores in some strata, but not others within a phenotype group. We conclude that families with type 1 diabetes plus MVCs are genetically different from those with diabetes alone. PMID- 29444169 TI - Monitoring chest compression quality during cardiopulmonary resuscitation: Proof of-concept of a single accelerometer-based feedback algorithm. AB - BACKGROUND: The use of real-time feedback systems to guide rescuers during cardiopulmonary resuscitation (CPR) significantly contributes to improve adherence to published resuscitation guidelines. Recently, we designed a novel method for computing depth and rate of chest compressions relying solely on the spectral analysis of chest acceleration. That method was extensively tested in a simulated manikin scenario. The purpose of this study is to report the results of this method as tested in human out-of-hospital cardiac arrest (OHCA) cases. MATERIALS AND METHODS: The algorithm was evaluated retrospectively with seventy five OHCA episodes recorded by monitor-defibrillators equipped with a CPR feedback device. The acceleration signal and the compression signal computed by the CPR feedback device were stored in each episode. The algorithm was continuously applied to the acceleration signals. The depth and rate values estimated every 2-s from the acceleration data were compared to the reference values obtained from the compression signal. The performance of the algorithm was assesed in terms of the sensitivity and positive predictive value (PPV) for detecting compressions and in terms of its accuracy through the analysis of measurement error. RESULTS: The algorithm reported a global sensitivity and PPV of 99.98% and 99.79%, respectively. The median (P75) unsigned error in depth and rate was 0.9 (1.7) mm and 1.0 (1.7) cpm, respectively. In 95% of the analyzed 2-s windows the error was below 3.5 mm and 3.1 cpm, respectively. CONCLUSIONS: The CPR feedback algorithm proved to be reliable and accurate when tested retrospectively with human OHCA episodes. A new CPR feedback device based on this algorithm could be helpful in the resuscitation field. PMID- 29444170 TI - Genotypic and phenotypic characterization of the Sdccag8Tn(sb-Tyr)2161B.CA1C2Ove mouse model. AB - Nephronophthisis-related ciliopathies (NPHP-RC) are a group of disorders that present with end-stage renal failure in childhood/adolescence, kidney cysts, retinal degeneration, and cerebellar hypoplasia. One disorder that shares clinical features with NPHP-RC is Bardet-Biedl Syndrome (BBS). Serologically defined colon cancer antigen 8 (SDCCAG8; also known as NPHP10 and BBS16) is an NPHP gene that is also associated with BBS. To better understand the patho mechanisms of NPHP and BBS caused by loss of SDCCAG8 function, we characterized an SDCCAG8 mouse model (Sdccag8Tn(sb-Tyr)2161B.CA1C2Ove) generated by Sleeping Beauty Transposon (SBT)-mediated insertion mutagenesis. Consistent with the previously reported, independent SDCCAG8 mouse models, our mutant mice display pre-axial polydactyly in their hind limbs. In addition, we report patterning defects in the secondary palate, brain abnormalities, as well as neonatal lethality associated with developmental defects in the lung in our mouse model. The neonatal lethality phenotype is genetic background dependent and rescued by introducing 129S6/SvEvTac background. Genetic modifier(s) responsible for this effect were mapped to a region between SNPs rs3714172 and rs3141832 on chromosome 11. While determining the precise genetic lesion in our mouse model, we found that SBT insertion resulted in a deletion of multiple exons from both Sdccag8 and its neighboring gene Akt3. We ascribe the patterning defects in the limb and the secondary palate as well as lung abnormalities to loss of SDCCAG8, while the developmental defects in the brain are likely due to the loss of AKT3. This mouse model may be useful to study features not observed in other SDCCAG8 models but cautions are needed in interpreting data. PMID- 29444172 TI - Motor and psychosocial impact of robot-assisted gait training in a real-world rehabilitation setting: A pilot study. AB - In the last decade robotic devices have been applied in rehabilitation to overcome walking disability in neurologic diseases with promising results. Robot assisted gait training (RAGT) using the Lokomat seems not only to improve gait parameters but also the perception of well-being. Data on the psychosocial patient-robot impact are limited, in particular in the real-world of RAGT, in the rehabilitation setting. During rehabilitation training, the Lokomat can be considered an "assistive device for movement". This allowed the use of the Psychosocial Impact of Assistive Device Scale- PIADS to describe patient interaction with the Lokomat. The primary aim of this pilot study was to evaluate the psychosocial impact of the Lokomat in an in-patient rehabilitation setting using the PIADS; secondary aims were to assess whether the psychosocial impact of RAGT is different between pathological sub-groups and if the Lokomat influenced functional variables (Functional Independence Measure scale-FIM and parameters provided by the Lokomat itself). Thirty-nine consecutive patients (69% males, 54.0+/-18.0 years) eligible for Lokomat training, with etiologically heterogeneous walking disabilities (Parkinson's Disease, n = 10; Spinal Cord Injury, n = 21; Ictus Event, n = 8) were enrolled. Patients were assessed with the FIM before and after rehabilitation with Lokomat, and the PIADS was administered after the rehabilitative period with Lokomat. Overall the PIADS score was positive (35.8+/-21.6), as well as the three sub-scales, pertaining to "ability", "adaptability" and "self-esteem" (17.2+/-10.4, 8.9+/-5.5 and 10.1+/ 6.6 respectively) with no between-group differences. All patients significantly improved in gait measure and motor FIM scale (difference after-before treatment values: 11.7+/-9.8 and 11.2+/-10.3 respectively), increased treadmill speed (0.4 +/- 0.2m/s), reduced body weight support (-14.0+/-9.5%) and guidance force (-13.1 +/- 10.7%). This pilot study indicates that Lokomat, in a real-world in-patient setting, may have a generalised approval, independent of disease, underlining the importance of the psycho-social framework for patients training with assistive robotic-devices. PMID- 29444171 TI - Reduced cognitive function, increased blood-brain-barrier transport and inflammatory responses, and altered brain metabolites in LDLr -/-and C57BL/6 mice fed a western diet. AB - Recent work suggests that diet affects brain metabolism thereby impacting cognitive function. Our objective was to determine if a western diet altered brain metabolism, increased blood-brain barrier (BBB) transport and inflammation, and induced cognitive impairment in C57BL/6 (WT) mice and low-density lipoprotein receptor null (LDLr -/-) mice, a model of hyperlipidemia and cognitive decline. We show that a western diet and LDLr -/- moderately influence cognitive processes as assessed by Y-maze and radial arm water maze. Also, western diet significantly increased BBB transport, as well as microvessel factor VIII in LDLr -/- and microglia IBA1 staining in WT, both indicators of activation and neuroinflammation. Interestingly, LDLr -/- mice had a significant increase in 18F fluorodeoxyglucose uptake irrespective of diet and brain 1H-magnetic resonance spectroscopy showed increased lactate and lipid moieties. Metabolic assessments of whole mouse brain by GC/MS and LC/MS/MS showed that a western diet altered brain TCA cycle and beta-oxidation intermediates, levels of amino acids, and complex lipid levels and elevated proinflammatory lipid mediators. Our study reveals that the western diet has multiple impacts on brain metabolism, physiology, and altered cognitive function that likely manifest via multiple cellular pathways. PMID- 29444173 TI - Transcriptome variations among human embryonic stem cell lines are associated with their differentiation propensity. AB - Human embryonic stem cells (hESCs) have the potential to form any cell type in the body, making them attractive cell sources in drug screening, regenerative medicine, disease and developmental processes modeling. However, not all hESC lines have the equal potency to generate desired cell types in vitro. Significant variations have been observed for the differentiation efficiency of various human ESC lines. The precise underpinning molecular mechanisms are still unclear. In this work, we compared transcriptome variations of four hESC lines H7, HUES1, HUES8 and HUES9. We found that hESC lines have different gene expression profiles, and these differentially expressed genes (DEGs) are significantly enriched in developmental processes, such as ectodermal, mesodermal and endodermal development. The enrichment difference between hESC lines was consistent with its lineage bias. Among these DEGs, some pluripotency factors and genes involved in signaling transduction showed great variations as well. The pleiotropic functions of these genes in controlling hESC identity and early lineage specification, implicated that different hESC lines may utilize distinct balance mechanisms to maintain pluripotent state. When the balance is broken in a certain environment, gene expression variation between them could impact on their different lineage specification behavior. PMID- 29444174 TI - Chromosome evolution in Cophomantini (Amphibia, Anura, Hylinae). AB - The hylid tribe Cophomantini is a diverse clade of Neotropical treefrogs composed of the genera Aplastodiscus, Boana, Bokermannohyla, Hyloscirtus, and Myersiohyla. The phylogenetic relationships of Cophomantini have been comprehensively reviewed in the literature, providing a suitable framework for the study of chromosome evolution. Employing different banding techniques, we studied the chromosomes of 25 species of Boana and 3 of Hyloscirtus; thus providing, for the first time, data for Hyloscirtus and for 15 species of Boana. Most species showed karyotypes with 2n = 2x = 24 chromosomes; some species of the B. albopunctata group have 2n = 2x = 22, and H. alytolylax has 2n = 2x = 20. Karyotypes are all bi-armed in most species presented, with the exception of H. larinopygion (FN = 46) and H. alytolylax (FN = 38), with karyotypes that have a single pair of small telocentric chromosomes. In most species of Boana, NORs are observed in a single pair of chromosomes, mostly in the small chromosomes, although in some species of the B. albopunctata, B. pulchella, and B. semilineata groups, this marker occurs on the larger pairs 8, 1, and 7, respectively. In Hyloscirtus, NOR position differs in the three studied species: H. alytolylax (4p), H. palmeri (4q), and H. larinopygion (1p). Heterochromatin is a variable marker that could provide valuable evidence, but it would be necesserary to understand the molecular composition of the C-bands that are observed in different species in order to test its putative homology. In H. alytolylax, a centromeric DAPI+ band was observed on one homologue of chromosome pair 2. The band was present in males but absent in females, providing evidence for an XX/XY sex determining system in this species. We review and discuss the importance of the different chromosome markers (NOR position, C-bands, and DAPI/CMA3 patterns) for their impact on the taxonomy and karyotype evolution in Cophomantini. PMID- 29444176 TI - Lack of usefulness of computed tomography for surveillance in patients with aggressive non-Hodgkin lymphoma. AB - Surveillance computed tomography (CT) is usual practice for patients with aggressive non-Hodgkin lymphoma (aNHL) in complete remission (CR). However, evidence to support this strategy is lacking. We retrospectively analyzed our institutional lymphoma registry, including patients with lymphoma consecutively enrolled from June 1995 to October 2016. Of 1,385 patients with aNHL, 664 achieved CR and were followed up with or without surveillance CT. Surveillance CT was performed for 609 patients every 3 or 6 months for the first 2 years, then every 6 or 12 months thereafter. Relapse was detected in 171 patients, of whom 152 underwent surveillance CT during follow-up. Of these 152 patients, asymptomatic relapse was detected in 67 (44%) using surveillance CT, and symptomatic relapse outside the surveillance interval was detected in the remaining 85 (56%). Detection of asymptomatic relapse using surveillance CT did not improve the overall or post-relapse survival in patients with relapsed aNHL. Surveillance CT interval (3 or 6 months) did not affect survival. No subgroups were identified that favored the use of surveillance CT to detect relapse. The results of this study suggest that routine surveillance CT in patients with aNHL to detect asymptomatic relapse might have a limited role in improving survival. CT is recommended when a relapse is clinically suspected. PMID- 29444175 TI - Tomographic optical imaging of cortical responses after crossing nerve transfer in mice. AB - To understand the neural mechanisms underlying the therapeutic effects of crossing nerve transfer for brachial plexus injuries in human patients, we investigated the cortical responses after crossing nerve transfer in mice using conventional and tomographic optical imaging. The distal cut ends of the left median and ulnar nerves were connected to the central cut ends of the right median and ulnar nerves with a sciatic nerve graft at 8 weeks of age. Eight weeks after the operation, the responses in the primary somatosensory cortex (S1) elicited by vibratory stimulation applied to the left forepaw were visualized based on activity-dependent flavoprotein fluorescence changes. In untreated mice, the cortical responses to left forepaw stimulation were mainly observed in the right S1. In mice with nerve crossing transfer, cortical responses to left forepaw stimulation were observed in the left S1 together with clear cortical responses in the right S1. We expected that the right S1 responses in the untreated mice were produced by thalamic inputs to layer IV, whereas those in the operated mice were mediated by callosal inputs from the left S1 to layer II/III of the right S1. To confirm this hypothesis, we performed tomographic imaging of flavoprotein fluorescence responses by macroconfocal microscopy. Flavoprotein fluorescence responses in layer IV were dominant compared to those in layer II/III in untreated mice. In contrast, responses in layer II/III were dominant compared to those in layer IV in operated mice. The peak latency of the cortical responses in the operated mice was longer than that in the untreated mice. These results confirmed our expectation that drastic reorganization in the cortical circuits was induced after crossing nerve transfer in mice. PMID- 29444178 TI - Heterogeneity in pulmonary emphysema: Analysis of CT attenuation using Gaussian mixture model. AB - PURPOSE: To utilize Gaussian mixture model (GMM) for the quantification of chronic obstructive pulmonary disease (COPD) and to evaluate the combined use of multiple types of quantification. MATERIALS AND METHODS: Eighty-seven patients (67 men, 20 women; age, 67.4 +/- 11.0 years) who had undergone computed tomography (CT) and pulmonary function test (PFT) were included. The heterogeneity of CT attenuation in emphysema (HC) was obtained by analyzing a distribution of CT attenuation with GMM. The percentages of low-attenuation volume in the lungs (LAV), wall area of bronchi (WA), and the cross-sectional area of small pulmonary vessels (CSA) were also calculated. The relationships between COPD quantifications and the PFT results were evaluated by Pearson's correlation coefficients and through linear models, with the best models selected using Akaike information criterion (AIC). RESULTS: The correlation coefficients with FEV1 were as follows: LAV, -0.505; HC, -0.277; CSA, 0.384; WA, -0.196. The correlation coefficients with FEV1/FVC were: LAV, -0.640; HC, -0.136; CSA, 0.288; WA, -0.131. For predicting FEV1, the smallest AIC values were obtained in the model with LAV, HC, CSA, and WA. For predicting FEV1/FVC, the smallest AIC values were obtained in the model with LAV and HC. In both models, the coefficient of HC was statistically significant (P-values = 0.000880 and 0.0441 for FEV1 and FEV1/FVC, respectively). CONCLUSION: GMM was applied to COPD quantification. The results of this study show that COPD severity was associated with HC. In addition, it is shown that the combined use of multiple types of quantification made the evaluation of COPD severity more reliable. PMID- 29444177 TI - Kidney-differentiated cells derived from Lowe Syndrome patient's iPSCs show ciliogenesis defects and Six2 retention at the Golgi complex. AB - Lowe syndrome is an X-linked condition characterized by congenital cataracts, neurological abnormalities and kidney malfunction. This lethal disease is caused by mutations in the OCRL1 gene, which encodes for the phosphatidylinositol 5 phosphatase Ocrl1. While in the past decade we witnessed substantial progress in the identification and characterization of LS patient cellular phenotypes, many of these studies have been performed in knocked-down cell lines or patient's cells from accessible cell types such as skin fibroblasts, and not from the organs affected. This is partially due to the limited accessibility of patient cells from eyes, brain and kidneys. Here we report the preparation of induced pluripotent stem cells (iPSCs) from patient skin fibroblasts and their reprogramming into kidney cells. These reprogrammed kidney cells displayed primary cilia assembly defects similar to those described previously in cell lines. Additionally, the transcription factor and cap mesenchyme marker Six2 was substantially retained in the Golgi complex and the functional nuclear-localized fraction was reduced. These results were confirmed using different batches of differentiated cells from different iPSC colonies and by the use of the human proximal tubule kidney cell line HK2. Indeed, OCRL1 KO led to both ciliogenesis defects and Six2 retention in the Golgi complex. In agreement with Six2's role in the suppression of ductal kidney lineages, cells from this pedigree were over represented among patient kidney-reprogrammed cells. We speculate that this diminished efficacy to produce cap mesenchyme cells would cause LS patients to have difficulties in replenishing senescent or damaged cells derived from this lineage, particularly proximal tubule cells, leading to pathological scenarios such as tubular atrophy. PMID- 29444179 TI - Capability beliefs on, and use of evidence-based practice among four health professional and student groups in geriatric care: A cross sectional study. AB - Implementation of evidence-based practice (EBP) is a complex task. This study, conducted in an acute geriatric setting, aims to compare self-reported capability beliefs on EBP between health professionals and students, and to compare the use of EBP between health professional groups. Occupational therapists, physicians, physiotherapists and registered nurses with three or more months' employment, and all students from the occupational therapy, medical, physiotherapy and nursing programs, who had conducted workplace learning at the department, were invited. Data on capability beliefs and use of EBP were collected using the Evidence-based Practice Capabilities Beliefs Scale assessing six activities of EBP: formulate questions; search databases; search other sources; appraise research reports; participate in implementation in practice; and participate in evaluation. Descriptive and inferential statistics were used. Capability beliefs on EBP: The health professionals (n = 101; response rate 80%) reported high on search other sources but less on appraise research reports. The students (n = 124; response rate 73%) reported high on all EBP activities. The health professionals reported significantly higher on search other sources than the students. The students reported significantly higher on formulate questions and appraise research reports than the health professionals. No significant differences were identified between the health professional groups or between the student groups. Use of EBP: Health professionals reported wide-ranging use from several times each month to once every six months. The physicians reported significantly more frequent use than registered nurses and occupational therapists. Health professionals supervising students reported more frequent use of appraise research reports than the non-supervising group. There is a need for improving the use of EBP, particularly among registered nurses and occupational therapists. Supervision of students might enhance the motivation among staff to increase the use of EBP and students' high EBP capability beliefs might inspire staff in this matter. PMID- 29444180 TI - The Bogazici face database: Standardized photographs of Turkish faces with supporting materials. AB - Many sets of human facial photographs produced in Western cultures are available for scientific research. We report here on the development of a face database of Turkish undergraduate student targets. High-resolution standardized photographs were taken and supported by the following materials: (a) basic demographic and appearance-related information, (b) two types of landmark configurations (for Webmorph and geometric morphometrics (GM)), (c) facial width-to-height ratio (fWHR) measurement, (d) information on photography parameters, (e) perceptual norms provided by raters. We also provide various analyses and visualizations of facial variation based on rating norms using GM. Finally, we found that there is sexual dimorphism in fWHR in our sample but that this is accounted for by body mass index. We present the pattern of associations between rating norms, GM and fWHR measurements. The database and supporting materials are freely available for scientific research purposes.

PMID- 29444182 TI - Towards phenotyping stroke: Leveraging data from a large-scale epidemiological study to detect stroke diagnosis. AB - OBJECTIVE: 1) To develop a machine learning approach for detecting stroke cases and subtypes from hospitalization data, 2) to assess algorithm performance and predictors on real-world data collected by a large-scale epidemiology study in the US; and 3) to identify directions for future development of high-precision stroke phenotypic signatures. MATERIALS AND METHODS: We utilized 8,131 hospitalization events (ICD-9 codes 430-438) collected from the Greater Cincinnati/Northern Kentucky Stroke Study in 2005 and 2010. Detailed information from patients' medical records was abstracted for each event by trained research nurses. By analyzing the broad list of demographic and clinical variables, the machine learning algorithms predicted whether an event was a stroke case and, if so, the stroke subtype. The performance was validated on gold-standard labels adjudicated by stroke physicians, and results were compared with stroke classifications based on ICD-9 discharge codes, as well as labels determined by study nurses. RESULTS: The best performing machine learning algorithm achieved a performance of 88.57%/93.81%/92.80%/93.30%/89.84%/98.01% (accuracy/precision/recall/F-measure/area under ROC curve/area under precision recall curve) on stroke case detection. For detecting stroke subtypes, the algorithm yielded an overall accuracy of 87.39% and greater than 85% precision on individual subtypes. The machine learning algorithms significantly outperformed the ICD-9 method on all measures (P value<0.001). Their performance was comparable to that of study nurses, with better tradeoff between precision and recall. The feature selection uncovered a subset of predictive variables that could facilitate future development of effective stroke phenotyping algorithms. DISCUSSION AND CONCLUSIONS: By analyzing a broad array of patient data, the machine learning technologies held promise for improving detection of stroke diagnosis, thus unlocking high statistical power for subsequent genetic and genomic studies. PMID- 29444183 TI - Nanoparticle-antagomiR based targeting of miR-31 to induce osterix and osteocalcin expression in mesenchymal stem cells. AB - Mesenchymal stem cells are multipotent adult stem cells capable of generating bone, cartilage and fat, and are thus currently being exploited for regenerative medicine. When considering osteogenesis, developments have been made with regards to chemical induction (e.g. differentiation media) and physical induction (e.g. material stiffness, nanotopography), targeting established early transcription factors or regulators such as runx2 or bone morphogenic proteins and promoting increased numbers of cells committing to osteo-specific differentiation. Recent research highlighted the involvement of microRNAs in lineage commitment and terminal differentiation. Herein, gold nanoparticles that confer stability to short single stranded RNAs were used to deliver MiR-31 antagomiRs to both pre osteoblastic cells and primary human MSCs in vitro. Results showed that blocking miR-31 led to an increase in osterix protein in both cell types at day 7, with an increase in osteocalcin at day 21, suggesting MSC osteogenesis. In addition, it was noted that antagomiR sequence direction was important, with the 5 prime reading direction proving more effective than the 3 prime. This study highlights the potential that miRNA antagomiR-tagged nanoparticles offer as novel therapeutics in regenerative medicine. PMID- 29444184 TI - Qualitative thematic analysis of the phenomenology of near-death experiences. AB - Near-death experiences (NDEs) refer to profound psychological events that can have an important impact on the experiencers' (NDErs) lives. Previous studies have shown that NDEs memories are phenomenologically rich. In the present study, we therefore aimed to extract the common themes (referred to as "features" in the NDE literature) reported by NDErs by analyzing all the concepts stored in the narratives of their experiences. A qualitative thematic analysis has been carried out on 34 cardiac arrest survivors' NDE narratives. Our results shed the light on the structure of the narratives by identifying 10 "time-bounded" themes which refer to isolated events encountered during the NDE and 1 "transversal" theme which characterizes the whole narrative and generally appears as a retrospective comment of self-reflection on the experience. The division of narratives into themes provides us with detailed information about the vocabulary used by NDErs to describe their experience. This established thematic method enables a rigorous description of the phenomenon, ensuring the inclusion of all self-reported manifestations of themes in narratives. PMID- 29444185 TI - Humoral and cell-mediated immune responses after a booster dose of HBV vaccine in HIV-infected children, adolescents and young adults. AB - OBJECTIVE: HBV vaccine induces protective antibodies only in 23-56% of HIV infected children. The aim of our study is to evaluate the immunologic effects of a booster dose of HBV vaccine in HIV-infected youth. DESIGN: 53 young HIV infected patients in whom HBV vaccination did not elicit protective Ab titers were enrolled. All patients were on ART with optimal immunological and viral response. METHOD: All patients received a booster dose of HBV vaccine (HBVAXPRO 10 MUg i.m.). HBV-specific Ab titer, viral load and CD4+ T cells were measured at baseline (T0), T1, T6 and T12 months. In a subgroup of 16 patients HBV-specific cell mediated immune responses were evaluated at baseline, at T1 and T6. RESULTS: The booster dose induced seroconversion in 51% of patients at T1, 57% at T6, and49% at T12; seroconversion rate was significantly correlated with CD4+T cells at T0 and to the CD4 nadir. The booster dose induced HBV-specific cell mediated immunity at T6 mainly in Responders (Rs): Effector Memory CD8+T cells, HBV specific TNFalpha-, IFNgamma-, granzyme secreting CD8+ T cells and IL2-secreting CD4+ T cells were significantly increased in Rs compared to T0. In Non Responders (NRs), HBV-specific IL2-secreting CD4+ T cells, Central and Effector Memory CD8+ T cells were the only parameters modified at T6. CONCLUSIONS: Seroconversion induced by a booster dose of vaccine correlates with the development of T cell immunological memory in HIV-infected patients who did not respond to the standard immunization. Alternate immunization schedules need to be considered in NRs. PMID- 29444186 TI - Identification of fungi in shotgun metagenomics datasets. AB - Metagenomics uses nucleic acid sequencing to characterize species diversity in different niches such as environmental biomes or the human microbiome. Most studies have used 16S rRNA amplicon sequencing to identify bacteria. However, the decreasing cost of sequencing has resulted in a gradual shift away from amplicon analyses and towards shotgun metagenomic sequencing. Shotgun metagenomic data can be used to identify a wide range of species, but have rarely been applied to fungal identification. Here, we develop a sequence classification pipeline, FindFungi, and use it to identify fungal sequences in public metagenome datasets. We focus primarily on animal metagenomes, especially those from pig and mouse microbiomes. We identified fungi in 39 of 70 datasets comprising 71 fungal species. At least 11 pathogenic species with zoonotic potential were identified, including Candida tropicalis. We identified Pseudogymnoascus species from 13 Antarctic soil samples initially analyzed for the presence of bacteria capable of degrading diesel oil. We also show that Candida tropicalis and Candida loboi are likely the same species. In addition, we identify several examples where contaminating DNA was erroneously included in fungal genome assemblies.

AB - Real-time, quantitative measurement of muscle progenitor cell (myoblast) differentiation is an important tool for skeletal muscle research and identification of drugs that support skeletal muscle regeneration. While most quantitative tools rely on sacrificial approach, we developed a double fluorescent tagging approach, which allows for dynamic monitoring of myoblast differentiation through assessment of fusion index and nuclei count. Fluorescent tagging of both the cell cytoplasm and nucleus enables monitoring of cell fusion and the formation of new myotube fibers, similar to immunostaining results. This labeling approach allowed monitoring the effects of Myf5 overexpression, TNFalpha, and Wnt agonist on myoblast differentiation. It also enabled testing the effects of surface coating on the fusion levels of scaffold-seeded myoblasts. The double fluorescent labeling of myoblasts is a promising technique to visualize even minor changes in myogenesis of myoblasts in order to support applications such as tissue engineering and drug screening.

AB - Adult T-cell leukaemia/lymphoma (ATL) arises from chronic non-malignant human T lymphotropic virus type-1 (HTLV-1) infection which is characterized by high plasma pro-inflammatory cytokines whereas ATL is characterized by high plasma anti-inflammatory (IL-10) concentrations. The poor prognosis of ATL is partly ascribed to disease-associated immune suppression. ATL cells have a CD4+CCR4+CD26 CD7- immunophenotype but infected cells with this immunophenotype ('ATL-like' cells) are also present in non-malignant HTLV-1 infection. We hypothesized that 'ATL-like' and ATL cells have distinct cytokine producing capacity and a switch in the cytokines produced occurs during leukemogenesis. Seventeen asymptomatic carriers (ACs), 28 patients with HTLV-1-associated myelopathy (HAM) and 28 with ATL were studied. Plasma IL-10 concentration and the absolute frequency of IL-10 producing CD4+ T cells were significantly higher in patients with ATL compared to AC. IL-10-producing ATL cells were significantly more frequent than 'ATL-like' cells. The cytokine-producing cells were only a small fraction of ATL cells. Clonality analysis revealed that even in patients with ATL the ATL cells were composed not only of a single dominant clone (putative ATL cells) but also tens of non-dominant infected clones ('ATL-like' cells). The frequency of cytokine producing cells showed a strong inverse correlation with the relative abundance of the largest clone in ATL cells suggesting that the putative ATL cells were cytokine non-producing and that the 'ATL-like' cells were the primary cytokine producers. These findings were confirmed by RNAseq with cytokine mRNA expression in ATL cells in patients with ATL (confirmed to be composed of both putative ATL and 'ATL-like' cells by TCR analysis) significantly lower compared to 'ATL-like' cells in patients with non-malignant HTLV-1 infection (confirmed to be composed of hundreds of non-dominant clones by TCR analysis). A significant inverse correlation between the relative abundance of the largest clone and cytokine mRNA expression was also confirmed. Finally, 'ATL-like' cells produced less pro- and more anti-inflammatory cytokines than non 'ATL-like' CD4+ cells (which are predominantly HTLV uninfected). In summary, HTLV-1 infection of CD4+ T cells is associated with a change in cytokine producing capacity and dominant malignant clonal growth is associated with loss of cytokine producing capacity. Non dominant clones with 'ATL-like' cells contribute to plasma cytokine profile in patients with non-malignant HTLV-1 infection and are also present in patient with ATL. PMID- 29444189 TI - Cross-priming induces immunodomination in the presence of viral MHC class I inhibition. AB - Viruses have evolved mechanisms of MHCI inhibition in order to evade recognition by cytotoxic CD8+ T cells (CTLs), which is well-illustrated by our prior studies on cowpox virus (CPXV) that encodes potent MHCI inhibitors. Deletion of CPXV viral MHCI inhibitors markedly attenuated in vivo infection due to effects on CTL effector function, not priming. However, the CTL response to CPXV in C57BL/6 mice is dominated by a single peptide antigen presented by H-2Kb. Here we evaluated the effect of viral MHCI inhibition on immunodominant (IDE) and subdominant epitopes (SDE) as this has not been thoroughly examined. We found that cross priming, but not cross-dressing, is the main mechanism driving IDE and SDE CTL responses following CPXV infection. Secretion of the immunodominant antigen was not required for immunodominance. Instead, immunodominance was caused by CTL interference, known as immunodomination. Both immunodomination and cross-priming of SDEs were not affected by MHCI inhibition. SDE-specific CTLs were also capable of exerting immunodomination during primary and secondary responses, which was in part dependent on antigen abundance. Furthermore, CTL responses directed solely against SDEs protected against lethal CPXV infection, but only in the absence of the CPXV MHCI inhibitors. Thus, both SDE and IDE responses can contribute to protective immunity against poxviruses, implying that these principles apply to poxvirus-based vaccines. PMID- 29444191 TI - Restoration of services in disrupted infrastructure systems: A network science approach. AB - Due to the ubiquitous nature of disruptive extreme events, functionality of the critical infrastructure systems (CIS) is constantly at risk. In case of a disruption, in order to minimize the negative impact to the society, service networks operating on the CIS should be restored as quickly as possible. In this paper, we introduce a novel network science inspired measure to quantify the criticality of components within a disrupted service network and develop a restoration heuristic (Cent-Restore) that prioritizes restoration efforts based on this measure. As an illustrative case study, we consider a road network blocked by debris in the aftermath of a natural disaster. The debris obstructs the flow of relief aid and search-and-rescue teams between critical facilities and disaster sites, debilitating the emergency service network. In this context, the problem is defined as finding a schedule to clear the roads with the limited resources. First, we develop a mixed-integer programming model for the problem. Then we validate the efficiency and accuracy of the Cent-Restore heuristic on randomly generated instances by comparing it to the model. Furthermore, we use Cent-Restore to recommend real-time restoration plans for disrupted road networks of Boston and Manhattan and analyze the performance of the plans over time through resilience curves. We compare Cent-Restore to the current restoration guidelines proposed by FEMA and other strategies that prioritize the restoration efforts based on different measures. As a result we confirm the importance of including specific post-disruption attributes of the networks to create effective restoration strategies. Moreover, we explore the relationship between a service network's resilience and its topological and operational characteristics under different disruption scenarios. The methods and insights provided in this work can be extended to other disrupted large-scale critical infrastructure systems in which the ultimate goal is to enable the functions of the overlaying service networks.

PMID- 29444190 TI - Bone marrow mesenchymal stem cell-derived exosomal miR-21 protects C-kit+ cardiac stem cells from oxidative injury through the PTEN/PI3K/Akt axis. AB - Stem cell (SC) therapy for ischemic cardiomyopathy is hampered by poor survival of the implanted cells. Recently, SC-derived exosomes have been shown to facilitate cell proliferation and survival by transporting various proteins and non-coding RNAs (such as microRNAs and lncRNAs). In this study, miR-21 was highly enriched in exosomes derived from bone marrow mesenchymal stem cells (MSCs). Interestingly, exosomes collected from hydrogen peroxide (H2O2)-treated MSCs (H Exo) contained higher levels of miR-21 than exosomes released from MSCs under normal conditions (N-Exo). The pre-treatment of C-kit+ cardiac stem cells (CSCs) with H-Exos resulted in significantly increased levels of miR-21 and phosphor-Akt (pAkt) and decreased levels of PTEN, which is a known target of miR-21. AnnexinV FITC/PI analysis further demonstrated that the degree of oxidative stress-induced apoptosis was markedly lower in H-Exo-treated C-kit+ CSCs than that in N-Exo treated cells. These protective effects could be blocked by both a miR-21 inhibitor and the PI3K/Akt inhibitor LY294002. Therefore, exosomal miR-21 derived from H2O2-treated MSCs could be transported to C-kit+ cardiac stem cells to functionally inhibit PTEN expression, thereby activating PI3K/AKT signaling and leading to protection against oxidative stress-triggered cell death. Thus, exosomes derived from MSCs could be used as a new therapeutic vehicle to facilitate C-kit+ CSC therapies in the ischemic myocardium. PMID- 29444194 TI - Scratching Beneath the Surface. PMID- 29444195 TI - Decrease in Inpatient Telemetry Utilization Through a System-Wide Electronic Health Record Change and a Multifaceted Hospitalist Intervention. AB - BACKGROUND: Unnecessary telemetry monitoring contributes to healthcare waste. OBJECTIVE: To evaluate the impact of 2 interventions to reduce telemetry utilization. DESIGN, SETTING, PATIENTS: A 2-group retrospective, observational pre- to postintervention study of 35,871 nonintensive care unit (ICU) patients admitted to 1 academic medical center. INTERVENTION: On the hospitalist service, we implemented a telemetry reduction intervention including education, process change, routine feedback, and a financial incentive between January 2015 and June 2015. In July 2015, a system-wide change to the telemetry ordering process was introduced. MEASUREMENTS: The primary outcome was telemetry utilization, measured as the percentage of daily room charges for telemetry. Secondary outcomes were mortality, escalation of care, code event rate, and appropriateness of telemetry utilization. Generalized linear models were used to evaluate changes in outcomes while adjusting for patient factors. RESULTS: Among hospitalist service patients, telemetry utilization was reduced by 69% (95% confidence interval [CI], -72% to 64%; P < .001), whereas on other services the reduction was a less marked 22% (95% CI, -27% to -16%; P < .001). There were no significant increases in mortality, code event rates, or care escalation, and there was a trend toward improved utilization appropriateness. CONCLUSIONS: Although electronic telemetry ordering changes can produce decreases in hospital-wide telemetry monitoring, a multifaceted intervention may lead to an even larger decline in utilization rates. Whether these changes are durable cannot be ascertained from our study.

PMID- 29444197 TI - A Single, Post-ACTH Cortisol Measurement to Screen for Adrenal Insufficiency in the Hospitalized Patient. AB - BACKGROUND: Cosyntropin stimulation testing (CST) is used to screen patients for adrenal insufficiency (AI). Traditionally, CST includes baseline cortisol concentration, the administration of cosyntropin, and cortisol concentration at 30 and 60 minutes poststimulation. There is debate surrounding the utility of testing and cut-off points for concentrations at each time point. OBJECTIVE: To determine if a single cortisol measurement at 30 or 60 minutes could replace the traditional approach. DESIGN: looked retrospectively at inpatients who underwent standard, high-dose CST (n = 702) and evaluated the number of patients who would screen positive for AI by using a single time point (30 or 60 minutes) compared with the traditional CST. SETTING: A tertiary-care, academic medical center. PATIENTS: Hospital inpatients present between January 2012 and September 2013. RESULTS: Of tests, 84.3% were normal, which was defined as at least 1 cortisol concentration of 18 mcg/dL or higher at any time after stimulation. The average 60-minute concentration was higher than the average 30-minute concentration (P < .001). A single 60-minute concentration is 100% concordant with the full CST in the intensive care unit (ICU) subgroup and 99.6% concordant in floor patients. A single 30-minute concentration is significantly less concordant, 91.9% and 86.9%, in the ICU and floor subgroups, respectively. CONCLUSIONS: Overall, a single 60 minute cortisol concentration to screen for AI was 99.7% concordant with the traditional CST, and the positive percent agreement was 98%. Fewer false-positive screens would occur with a single 60-minute cortisol concentration compared with a single 30-minute concentration (P < .001). High-dose CST screening may safely be interpreted with single 60-minute poststimulation cortisol serum concentrations.

AB - The objective of this study was to evaluate the effectiveness of precise three dimensional hydroxyapatite printed micro- and macrochannel devices for alveolar ridge augmentation in a canine model. All grafts induced minimal inflammatory and fibrotic reactions. Examination of undecalcified sections revealed that both types of grafts demonstrated bone ingrowth. The majority of the bone growth into the block graft was into the channels, though a portion grew directly into the construct in the form of small bony spicules. In conclusion, bone ingrowth was readily demonstrated in the middle of the implanted printed devices. PMID- 29444199 TI - Exposure to hexavalent chromium in welders: Results of the WELDOX II field study. AB - Objectives: Exposure to hexavalent chromium (Cr(VI)) has been primarily studied in chromate production. Here, we measured personal exposure to respirable Cr(VI) together with airborne and urinary Cr and Ni in welders to explore levels and associations between various measures of exposure. Methods : Shift concentrations of Cr(VI), Cr, and Ni were measured in respirable welding fumes in 50 men who used either gas metal arc welding (GMAW) (n = 24) or tungsten inert gas welding (TIG) (n = 19) as their major technique. Cr and Ni were determined in pre- and post-shift urine samples. Concentrations below the limit of quantification (LOQ) were multiply imputed. Spearman correlation coefficients (rs) were calculated with 95% confidence intervals (CIs) to explore associations between the exposure variables, and regression models were applied to estimate the effect of the parent metal on the urinary concentration. Results : Regarding the respirable Cr(VI), 62% of the measurements were below the LOQ, the 75th percentile was 0.50 ug m-3, and 8 out of 50 (16%) welders exceeded 1 ug m-3. The highest shift concentration that occurred as a result of shielded metal arc welding (SMAW) was 180 ug m-3. The Cr(VI) content in total Cr ranged from 4 to 82% (median 20%), although the concentration correlated with total Cr (rs 0.55, 95% CI 0.46; 0.64). The correlation between Cr(VI) and Ni was weaker (rs 0.42, 95% CI 0.34; 0.51) than that between total Cr and Ni in welding fumes (rs 0.83, 95% CI 0.74; 0.92). Both Cr(VI) and total Cr influenced the urinary Cr concentrations in post-shift samples (P = 0.0008 and P <= 0.0001, respectively). The airborne shift exposure was a weaker determinant than the Cr content in pre-shift urine samples, which strongly correlated with post-shift urinary Cr (rs 0.78, 95% CI 0.69; 0.87). Conclusions : The Cr(VI) content in total Cr varied considerably in welding fumes. The majority of welders using GMAW or TIG presented with shift concentrations of respirable Cr(VI) below 1 ug m-3. However, very high Cr(VI) concentrations may occur, for example in SMAW. The urinary concentration of total Cr, cannot be used to precisely determine the shift concentration of respirable Cr(VI) in welders. PMID- 29444200 TI - Loss of Sirt3 accelerates arterial thrombosis by increasing formation of neutrophil extracellular traps and plasma tissue factor activity. AB - Aims: Sirtuin 3 (Sirt3) is a mitochondrial, nicotinamide adenine dinucleotide (NAD+)-dependent deacetylase that reduces oxidative stress by activation of superoxide dismutase 2 (SOD2). Oxidative stress enhances arterial thrombosis. This study investigated the effects of genetic Sirt3 deletion on arterial thrombosis in mice in an inflammatory setting and assessed the clinical relevance of these findings in patients with ST-elevation myocardial infarction (STEMI). Methods and results: Using a laser-induced carotid thrombosis model with lipopolysaccharide (LPS) challenge, in vivo time to thrombotic occlusion in Sirt3 /- mice (n = 6) was reduced by half compared to Sirt3+/+ wild-type (n = 8, P < 0.01) controls. Ex vivo analyses of whole blood using rotational thromboelastometry revealed accelerated clot formation and increased clot stability in Sirt3-/- compared to wild-type blood. rotational thromboelastometry of cell-depleted plasma showed accelerated clotting initiation in Sirt3-/- mice, whereas overall clot formation and firmness remained unaffected. Ex vivo LPS induced neutrophil extracellular trap formation was increased in Sirt3-/- bone marrow-derived neutrophils. Plasma tissue factor (TF) levels and activity were elevated in Sirt3-/- mice, whereas plasma levels of other coagulation factors and TF expression in arterial walls remained unchanged. SOD2 expression in bone marrow -derived Sirt3-/- neutrophils was reduced. In STEMI patients, transcriptional levels of Sirt3 and its target SOD2 were lower in CD14+ leukocytes compared with healthy donors (n = 10 each, P < 0.01). Conclusions: Sirt3 loss-of-function enhances experimental thrombosis in vivo via an increase of neutrophil extracellular traps and elevation of TF suggesting thrombo protective effects of endogenous Sirt3. Acute coronary thrombosis in STEMI patients is associated with lower expression levels of SIRT3 and SOD2 in CD14+ leukocytes. Therefore, enhancing SIRT3 activity by pan-sirtuin activating NAD+ boosters may provide a novel therapeutic target to prevent or treat thrombotic arterial occlusion in myocardial infarction or stroke. PMID- 29444201 TI - Hierarchical analysis of RNA-seq reads improves the accuracy of allele-specific expression. AB - Motivation: Allele-specific expression (ASE) refers to the differential abundance of the allelic copies of a transcript. RNA sequencing (RNA-seq) can provide quantitative estimates of ASE for genes with transcribed polymorphisms. When short-read sequences are aligned to a diploid transcriptome, read-mapping ambiguities confound our ability to directly count reads. Multi-mapping reads aligning equally well to multiple genomic locations, isoforms or alleles can comprise the majority (>85%) of reads. Discarding them can result in biases and substantial loss of information. Methods have been developed that use weighted allocation of read counts but these methods treat the different types of multi reads equivalently. We propose a hierarchical approach to allocation of read counts that first resolves ambiguities among genes, then among isoforms, and lastly between alleles. We have implemented our model in EMASE software (Expectation-Maximization for Allele Specific Expression) to estimate total gene expression, isoform usage and ASE based on this hierarchical allocation. Results: Methods that align RNA-seq reads to a diploid transcriptome incorporating known genetic variants improve estimates of ASE and total gene expression compared to methods that use reference genome alignments. Weighted allocation methods outperform methods that discard multi-reads. Hierarchical allocation of reads improves estimation of ASE even when data are simulated from a non-hierarchical model. Analysis of RNA-seq data from F1 hybrid mice using EMASE reveals widespread ASE associated with cis-acting polymorphisms and a small number of parent-of-origin effects.

PMID- 29444204 TI - Formation of a subero-lignified apical deposit in root tip of radish (Raphanus sativus) as a response to copper stress. AB - Background and Aims: Heavy metals induce changes in root metabolism and physiology, which can lead to a complex remodelling of the root system. The final morphological responses of radish (Raphanus sativus) roots exposed to toxic concentrations of the heavy metal (Cu) include root growth inhibition, differentiation of xylem vessels close to the root tip, enhanced suberin lamellae deposition and enhanced lateral root production. Recently, we have found that such changes in root morphology and anatomy are coupled to the formation of a subero-lignified apical deposit (SLAD) very close to the root tip. Methods: To clarify the details of the formation of a SLAD in the root tip, we conducted experiments with radish roots exposed to a high Cu concentration (60 um). Histochemical analysis of lignin and suberin as well as analysis of spatial temporal characteristics of SLAD formation were performed by bright-field, fluorescence and confocal microscopy. Key Results: This unique structure, not longer than 100 um, consists of modified cell walls of the central cylinder that are encircled by a short cylinder of prematurely suberized endodermal cells. A SLAD starts to form, in both primary and lateral roots, after cessation of root elongation, and it is coupled with xylem differentiation and root branching close to the root apex. We noticed that deposition of phenolic substances into a SLAD, mainly suberin in the endodermis, is spatially separated from suberization or lignification in basally located endodermis. Conclusions: Although the main reason for formation of a SLAD is elusive, we suggest that it is a part of stress induced responses which relate to decreased root growth or permeability in heavy metal stress.

PMID- 29444206 TI - Grimmiaceae in the Early Cretaceous: Tricarinella crassiphylla gen. et sp. nov. and the value of anatomically preserved bryophytes. AB - Background and Aims: Widespread and diverse in modern ecosystems, mosses are rare in the fossil record, especially in pre-Cenozoic rocks. Furthermore, most pre Cenozoic mosses are known from compression fossils, which lack detailed anatomical information. When preserved, anatomy significantly improves resolution in the systematic placement of fossils. Lower Cretaceous (Valanginian) deposits on Vancouver Island (British Columbia, Canada) contain a diverse anatomically preserved flora including numerous bryophytes, many of which have yet to be characterized. Among them is the grimmiaceous moss described here. Methods: One fossil moss gametophyte preserved in a carbonate concretion was studied in serial sections prepared using the cellulose acetate peel technique. Key Results: Tricarinella crassiphylla gen. et sp. nov. is a moss with tristichous phyllotaxis and strongly keeled leaves. The combination of an acrocarpous condition (inferred based on a series of morphological features), a central conducting strand, a homogeneous leaf costa and a lamina with bistratose portions and sinuous cells, and multicellular gemmae, supports placement of Tricarinella in family Grimmiaceae. Tricarinella is similar to Grimmia, a genus that exhibits broad morphological variability. However, tristichous phyllotaxis and especially the lamina, bistratose at the base but not in distal portions of the leaf, set Tricarinella apart as a distinct genus. Conclusions: Tricarinella crassiphylla marks the oldest record for both family Grimmiaceae and sub-class Dicranidae, providing a hard minimum age (136 million years) for these groups. The fact that this fossil could be placed in an extant family, despite a diminutive size, emphasizes the considerable resolving power of anatomically preserved bryophyte fossils, even when recovered from allochthonous assemblages of marine sediments, such as the Apple Bay flora. Discovery of Tricarinella re-emphasizes the importance of paleobotanical studies as the only approach allowing access to a significant segment of biodiversity, the extinct biodiversity, which is unattainable by other means of investigation.

PMID- 29444207 TI - The functional network signature of heterogeneity in freezing of gait. AB - Freezing of gait is a complex, heterogeneous, and highly variable phenomenon whose pathophysiology and neural signature remains enigmatic. Evidence suggests that freezing is associated with impairments across cognitive, motor and affective domains; however, most research to date has focused on investigating one axis of freezing of gait in isolation. This has led to inconsistent findings and a range of different pathophysiological models of freezing of gait, due in large part to the tendency for studies to investigate freezing of gait as a homogeneous entity. To investigate the neural mechanisms of this heterogeneity, we used an established virtual reality paradigm to elicit freezing behaviour in 41 Parkinson's disease patients with freezing of gait and examined individual differences in the component processes (i.e. cognitive, motor and affective function) that underlie freezing of gait in conjunction with task-based functional MRI. First, we combined three unique components of the freezing phenotype: impaired set-shifting ability, step time variability, and self reported anxiety and depression in a principal components analysis to estimate the severity of freezing behaviour with a multivariate approach. By combining these measures, we were then able to interrogate the pattern of task-based functional connectivity associated with freezing (compared to normal foot tapping) in a sub-cohort of 20 participants who experienced sufficient amounts of freezing during task functional MRI. Specifically, we used the first principal component from our behavioural analysis to classify patterns of functional connectivity into those that were associated with: (i) increased severity; (ii) increased compensation; or (iii) those that were independent of freezing severity. Coupling between the cognitive and limbic networks was associated with 'worse freezing severity', whereas anti-coupling between the putamen and the cognitive and limbic networks was related to 'increased compensation'. Additionally, anti-coupling between cognitive cortical regions and the caudate nucleus were 'independent of freezing severity' and thus may represent common neural underpinnings of freezing that are unaffected by heterogenous factors. Finally, we related these connectivity patterns to each of the individual components (cognitive, motor, affective) in turn, thus exposing latent heterogeneity in the freezing phenotype, while also identifying critical functional network signatures that may represent potential targets for novel therapeutic intervention. In conclusion, our findings provide confirmatory evidence for systems-level impairments in the pathophysiology of freezing of gait and further advance our understanding of the whole-brain deficits that mediate symptom expression in Parkinson's disease. PMID- 29444208 TI - Death on demand? An analysis of physician-administered euthanasia in The Netherlands. AB - Background: Physician-administered euthanasia (PAE) was legalized, along with physician-assisted suicide (PAS), in The Netherlands in 2001. Sources of data: Annual reports of the Dutch Regional Euthanasia Review Committees, the committees' 2015 published Code of Practice and research studies. Areas of agreement: There is a general openness about the practice of PAE/PAS in The Netherlands and an avoidance of misleading euphemisms. The 2001 law also includes arrangements for post-event review of PAE/PAS decisions. Areas of controversy: Rising numbers of annually reported deaths from PAE and uncertainty over actual numbers. Movement away from the principle that euthanasia must take place within an established doctor-patient relationship. Increasing extension of the 2001 law to people with mental health conditions, dementia and multiple co-morbidities. Nature of the post-event scrutiny applied to reported cases. Growing points: The predominance of PAE over PAS where both are legalized raises questions over how these two acts are perceived and whether there are implications for such laws. Areas for timely research: Are the criteria for PAE/PAS in the 2001 law appropriate for a law of this nature? What should be the respective roles of the second-opinion doctors and the review committees? PMID- 29444209 TI - Geranylgeranyl pyrophosphate synthase facilitates the organization of cardiomyocytes during mid-gestation through modulating protein geranylgeranylation in mouse heart. AB - Aims: With the maturation of placenta, ventricular chamber maturation enhances cardiac contractile performance to adapt to the metabolic demand of growing embryo. The organization of cardiomyocytes is required for the morphological remodelling in ventricular chamber maturation. However, the mechanism governing the establishment of cardiac cytoarchitecture during ventricular chamber maturation is still poorly studied. Methods and results: Here, we found that the expression of geranylgeranyl pyrophosphate synthase (Ggpps), which mediates protein geranylgeranylation, increased in the mouse heart after the onset of placental function. By using different Cre lines, we found that the cardiac inactivation of Ggpps by the Nkx2.5Cre/+ line disrupted protein geranylgeranylation as early as E9.5, which affected ventricular chamber maturation and resulted in mid-gestational embryonic lethality. In contrast, alpha-SMA-Cre line mediated the disruption of protein geranylgeranylation from E13.5 did not affect embryonic heart development. Further analysis of Nkx2.5Cre/+; Ggppsfl/fl mutants showed that the loss of Ggpps caused disorganized cardiac cytoarchitecture as early as E11.5 by disturbing cell-cell junctions. Ggpps inactivation decreased Rho GTPase geranylgeranylation and their activity, which might account for the disruption of cell-cell junctions. Moreover, elevating the protein geranylgeranylation by supplement of geranylgeranyl pyrophosphate (GGPP) could recover the Ggpps deficient induced defects of cytoarchitecture and cell-cell junctions in vitro and in vivo. Conclusion: Our present study demonstrates that GGPPS-mediated protein geranylgeranylation plays an indispensable role in the ventricular chamber maturation and acts as a stage specific signal to regulate the establishment of cardiac cytoarchitecture during mid-gestation.

AB - See Meschia (doi:10.1093/brain/awy066) for a scientific commentary on this article.Vein of Galen aneurysmal malformation is a congenital anomaly of the cerebral vasculature representing 30% of all paediatric vascular malformations. We conducted whole exome sequencing in 19 unrelated patients presenting this malformation and subsequently screened candidate genes in a cohort of 32 additional patients using either targeted exome or Sanger sequencing. In a cohort of 51 patients, we found five affected individuals with heterozygous mutations in EPHB4 including de novo frameshift (p.His191Alafs*32) or inherited deleterious splice or missense mutations predicted to be pathogenic by in silico tools. Knockdown of ephb4 in zebrafish embryos leads to specific anomalies of dorsal cranial vessels including the dorsal longitudinal vein, which is the orthologue of the median prosencephalic vein and the embryonic precursor of the vein of Galen. This model allowed us to investigate EPHB4 loss-of-function mutations in this disease by the ability to rescue the brain vascular defect in knockdown zebrafish co-injected with wild-type, but not truncated EPHB4, mimicking the p.His191Alafs mutation. Our data showed that in both species, loss of function mutations of EPHB4 result in specific and similar brain vascular development anomalies. Recently, EPHB4 germline mutations have been reported in non-immune hydrops fetalis and in cutaneous capillary malformation-arteriovenous malformation. Here, we show that EPHB4 mutations are also responsible for vein of Galen aneurysmal malformation, indicating that heterozygous germline mutations of EPHB4 result in a large clinical spectrum. The identification of EPHB4 pathogenic mutations in patients presenting capillary malformation or vein of Galen aneurysmal malformation should lead to careful follow-up of pregnancy of carriers for early detection of anomaly of the cerebral vasculature in order to propose optimal neonatal care. Endovascular embolization indeed greatly improved the prognosis of patients. PMID- 29444213 TI - Systematic review: methodological flaws in racial/ethnic reporting for gastroesophageal reflux disease. AB - Health care disparities affecting the care of multiple disease groups are of growing concern internationally. Research guidelines, governmental institutions, and scientific journals have attempted to minimize disparities through policies regarding the collection and reporting of racial/ethnic data. One area where shortcomings remain is in gastroesophageal reflux disease (GERD). This systematic review, which adheres to the PRISMA statement, focuses on characterizing existing methodological weaknesses in research focusing on studies regarding the assessment, prevalence, treatment, and outcomes of GERD patients. Search terms included GERD and typical symptoms of GERD in ethnic groups or minorities. We reviewed 62 articles. The majority of studies did not report the race/ethnicity of all participants, and among those who did, very few followed accepted guidelines. While there were diverse participants, there was also diversity in the manner in which groups were labeled, making comparisons difficult. There appeared to be a disparity with respect to countries reporting race/ethnicity, with certain countries more likely to report this variable. Samples overwhelmingly consisted of the study country's majority population. The majority of studies justified the use of race/ethnicity as a study variable and investigated conceptually related factors such as socioeconomic status and environment. Yet, many studies wrote as if race/ethnicity reflected biological differences. Despite recommendations, it appears that GERD researchers around the world struggle with the appropriate and standard way to include, collect, report, and discuss race/ethnicity. Recommendations on ways to address these issues are included with the goal of preventing and identifying health care disparities.

AB - Evidence suggests that minimally invasive esophagectomy has several advantages with regard to short-term outcomes, compared to open esophagectomy in esophageal cancer patients. However, the impact of minimally invasive esophagectomy on long term respiratory function remains unknown. The objective of this study is to assess the association between use of the minimally invasive esophagectomy and long-term respiratory dysfunction in esophageal cancer patients after esophagectomy. This retrospective single institution study using prospectively collected data included 87 consecutive esophageal cancer patients who had undergone esophagectomy. All patients underwent a respiratory function test before, and one year after esophagectomy. Logistic regression analysis was used to compute the hazard ratio for long-term respiratory dysfunction. Minimally invasive esophagectomies were performed in 53 patients, and open esophagectomies in 34 patients. The two groups showed no significant differences in terms of postoperative complications and postoperative course. Nor were any differences observed between the two groups in terms of volume capacity (L) and forced expiratory volume 1.0 (L) before esophagectomy (P > 0.34). However, one year after esophagectomy, the decreases in volume capacity and forced expiratory volume 1.0 were significantly less in the minimally invasive esophagectomy group than in the open esophagectomy group (P = 0.04 and P = 0.007, respectively). Multivariate analyses revealed that minimally invasive esophagectomy was an independent favorable factor for maintenance of forced expiratory volume 1.0 (hazard ratio = 0.17, 95% confidence interval 0.04-0.71; P = 0.01). Minimally invasive esophagectomy may be an independent favorable factor for maintenance of long-term respiratory function in esophageal cancer patients after esophagectomy. PMID- 29444215 TI - Long-term outcomes of laparoscopic large hiatus hernia repair with nonabsorbable mesh. AB - The use of mesh to augment suture repair of large hiatus hernias remains controversial. Repair with mesh may help reduce the recurrence rate of primary repair, but concerns about the potential for serious complications, such as mesh erosion or stricturing, continue to limit its use. We aim to evaluate the long term outcome of primary hiatus hernia repair with lightweight polypropylene mesh (TiMesh) specifically looking at rates of clinical recurrence, dysphagia, and mesh-related complications. From a prospectively maintained database, 50 consecutive patients who underwent elective primary laparoscopic hiatal hernia repair with TiMesh between January 2005 and December 2007 were identified. Case notes and postoperative endoscopy reports were reviewed. Clinical outcomes were evaluated using a structured questionnaire, including a validated dysphagia score. Of the 50 patients identified, 36 (72%) were contactable for follow-up. At a median follow-up of 9 years, the majority of patients (97%) regarded their surgery as successful. Twelve patients (33%) reported a recurrence of their symptoms, but only 4 (11%) reported that their symptoms were as severe as prior to the surgery. There was no significant difference between pre- and postoperative dysphagia scores. Postoperative endoscopy reports were available for 32 patients at a median time point of 4 years postoperatively, none of which revealed any mesh-related complications. One patient had undergone a revision procedure for a recurrent hernia at another institution. In this series, primary repair of large hiatus hernia with nonabsorbable mesh was not associated with any adverse effects over time. Patient satisfaction with symptomatic outcome remained high in the long term. PMID- 29444216 TI - Long-term outcomes of single-ventricle palliation for pulmonary atresia with intact ventricular septum: Fontan survivors remain at risk of late myocardial ischaemia and death. AB - OBJECTIVES: The specific outcomes of patients with pulmonary atresia with intact ventricular septum late after Fontan palliation are unknown. Patients with smaller right ventricles and myocardial sinusoids are known to have worse survival in the first years of life. Whether the potential for coronary ischaemia affects the long-term outcomes of these patients after Fontan palliation is still unknown. METHODS: All patients with pulmonary atresia with intact ventricular septum who underwent the Fontan procedure from 1984 to 2016 in Australia and New Zealand were identified, and preoperative, perioperative and follow-up data were collected. RESULTS: Late follow-up data were available for 120 patients. The median length of follow-up after the Fontan procedure was 9.1 years (interquartile range 4.2-15.4 years). Late death occurred in 9% of patients (11/120). Six were sudden, unexpected deaths; 4 of those occurred in patients known to have right ventricle-dependent coronary circulation (RVDCC). Those with RVDCC had a higher incidence of sudden death (4/20 vs 2/100; P = 0.007). RVDCC was associated with late death (P = 0.01) and the development of myocardial ischaemia after Fontan completion (P < 0.001). The 10-year survival rate was 77% (95% confidence interval 56-100%) for patients with RVDCC vs 96% (95% confidence interval 92-100%) for patients without RVDCC. CONCLUSIONS: Long-term survival of patients with pulmonary atresia with intact ventricular septum after the Fontan procedure is excellent, but patients with RVDCC remain susceptible to coronary ischaemia and sudden death. Closer surveillance and investigation for exercise induced ischaemia may be necessary. PMID- 29444217 TI - Reply: Updated frequency analysis of spinocerebellar ataxia in China.

AB - Antarctic subice environments are diverse, underexplored microbial habitats. Here, we describe the ecophysiology and annotated genome of a Marinobacter strain isolated from a cold, saline, iron-rich subglacial outflow of the Taylor Glacier, Antarctica. This strain (BF04_CF4) grows fastest at neutral pH (range 6-10), is psychrophilic (range: 0 degrees C-20 degrees C), moderately halophilic (range: 0.8%-15% NaCl) and hosts genes encoding potential low temperature and high salt adaptations. The predicted proteome suggests it utilizes fewer charged amino acids than a mesophilic Marinobacter strain. BF04_CF4 has increased concentrations of membrane unsaturated fatty acids including palmitoleic (33%) and oleic (27.5%) acids that may help maintain cell membrane fluidity at low temperatures. The genome encodes proteins for compatible solute biosynthesis and transport, which are known to be important for growth in saline environments. Physiological verification of predicted metabolic functions demonstrate BF04_CF4 is capable of denitrification and may facilitate iron oxidation. Our data indicate that strain BF04_CF4 represents a new Marinobacter species, Marinobacter gelidimuriae sp. nov., that appears well suited for the subglacial environment it was isolated from. Marinobacter species have been isolated from other cold, saline environments in the McMurdo Dry Valleys and permanently cold environments globally suggesting that this lineage is cosmopolitan and ecologically relevant in icy brines. PMID- 29444219 TI - Complex cases of acquired pulmonary vein stenosis after radiofrequency ablation: is surgical repair an option? AB - Aims: Results of catheter based interventional treatment for pulmonary vein stenosis (PVS) following radiofrequency ablation (RFA) for atrial fibrillation remain suboptimal. Surgical repair may represent an alternative therapy, though long-term results have not been thoroughly investigated. Methods and results: We retrospectively assessed all patients in our centre undergoing surgical repair for radiofrequency-induced PVS. Data regarding surgical technique, clinical outcome, and rate of pulmonary vein (PV) restenosis were collected and analysed. Between 2004 and 2016, the rate for PVS resulting from RFA for atrial fibrillation in our institution was 0.79% (76/9633). During this period, five male patients with multiple PVS (3 +/- 1) underwent surgical repair of a total of 13 symptomatic PVS. Surgery was performed in a standard setting under cardiopulmonary bypass. Stenotic veins were incised longitudinally followed by a patch augmentation plasty using either bovine pericard (n = 7) or polytetrafluoroethylene (PTFE) patches (n = 5). Localization of incision was on the anterior side of the PV only (n = 8) or on both the anterior and posterior sides (n = 4). In one PVS lesion, mechanical dilatation was sufficient. Long-term follow-up after 60 +/- 69 months revealed an average restenosis rate of 38%. Restenosis was defined as narrowing >70%. All patients reported clinical improvement of symptoms at follow-up. Conclusion: Even in the era of wide circumferential lesions, PVS still occurs. While surgical PV patch plasty represents a valuable treatment option, restenosis remains an issue during follow up. Nevertheless, surgical repair achieves highly acceptable long-term results for RFA-acquired PVS. Hence, it should be routinely discussed as a therapeutic option in cases with multiple PVS. PMID- 29444220 TI - Trends in small-for-gestational age before and after the economic crisis in Spain. AB - The aim of this study was to evaluate trends in small-for-gestational age covering the period before and after the Spanish economic crisis, taking into account mother's age, nationality and the autonomous community where she resides. We performed a trend study including children born to fertile women in Spain between 2002 and 2013. Poisson mixed models showed that the prevalence of small for-gestational age increased following the onset of the crisis, and that a previous downward trend was interrupted.

PMID- 29444222 TI - Extracorporeal membrane oxygenation as a bridge to lung transplantation may not impact overall mortality risk after transplantation: results from a 7-year single centre experience. AB - OBJECTIVES: Extracorporeal membrane oxygenation (ECMO) has an important role in bridging patients to lung transplantation. In this study, we present our experience with pretransplant ECMO during the last 7 years and investigate its impact on graft outcomes. METHODS: Records of all lung-transplanted patients at our institution between January 2010 and April 2017 were retrospectively reviewed. Graft survival was compared between patients who required pretransplant ECMO (pre-Tx ECMO+) and patients who did not (pre-Tx ECMO-). Risk factors for in hospital mortality and graft survival were identified using a binary logistic regression and the Cox regression analyses, respectively. RESULTS: Among the 917 patients transplanted during the study period, 68 (7%) required ECMO as a bridge to transplantation [awake strategy, n = 57 (84%) patients]. Median bridging time was 9 days. Among pre-Tx ECMO+ patients, the need for haemodialysis at any point during bridging emerged as an independent risk factor for in-hospital mortality (odds ratio 7.79, 95% confidence interval 1.21-50.24; P = 0.031). Although in hospital mortality was significantly higher in pre-Tx ECMO+ versus pre-Tx ECMO- patients (15% vs 5%, P = 0.003), overall graft survival did not differ between groups (79% vs 90% and 61% vs 68% at 1 and 5 years, respectively, P = 0.13). Pretransplant ECMO did not emerge as a risk factor for graft survival in the multivariable analysis. CONCLUSIONS: If applied in selected patients in a high volume centre, pretransplant ECMO as a bridge to transplantation results in impaired, but still high in-hospital, survival and does not impact graft survival. PMID- 29444224 TI - A systematic review with meta-analysis of the prevalence of gastroesophageal reflux in congenital diaphragmatic hernia pediatric survivors. AB - Congenital diaphragmatic hernia survivors are a well-known group at risk for developing gastroesophageal reflux disease that may be particularly long-term severe. The aim of this study is to provide a systematic review of the prevalence of gastroesophageal reflux in infant and children survivors treated for congenital diaphragmatic hernia.Electronic and manual searches were performed with keywords related to congenital diaphragmatic hernia, gastroesophageal reflux disease, and epidemiology terms. Summary estimates of the prevalence were calculated. Effect model was chosen depending on heterogeneity (I2). Factors potentially related with the prevalence, including study quality or the diagnostic strategy followed, were assessed by subgroup and meta-regression analyses. Risk of publication bias was studied by funnel plot analysis and the Egger test.The search yielded 140 articles, 26 of which were included in the analyses and provided 34 estimates of prevalence: 21 in patients aged 12 months or younger, and 13 in older children. The overall prevalence of gastroesophageal reflux disease in infants was 52.7% (95% confidence interval [CI]: 43.2% to 62.1%, I2 = 88.7%) and, in children over 1 year old, 35.1% (95% CI: 25.4% to 45.3%, I2 = 73.5%). Significant clinical and statistical heterogeneity was found. The strategy chosen for gastroesophageal reflux diagnosis influenced the reported prevalence. The only estimate obtained with a systematic use of multichannel intraluminal impedance provided a higher prevalence in both age groups: 83.3% (95% CI: 67.2% to 93.6%) and 61.1% (95% CI: 43.5% to 76.9%) respectively. This last prevalence did not significantly differ from that obtained using only low risk of bias estimates.As a conclusion, gastroesophageal reflux disease is commonly observed after congenital diaphragmatic hernia repair and is almost constantly present in the first months of life. It may be underdiagnosed if systematically esophageal monitoring is not performed. This should be considered when proposing follow-up and management protocols for congenital diaphragmatic hernia survivors. PMID- 29444223 TI - GLP-1 Receptor Expression Within the Human Heart. AB - Glucagonlike peptide-1 receptor (GLP-1R) agonists, which are used to treat type 2 diabetes and obesity, reduce the rates of myocardial infarction and cardiovascular death. GLP-1R has been localized to the human sinoatrial node; however, its expression in ventricular tissue remains uncertain. Here we studied GLP-1R expression in the human heart using GLP-1R-directed antisera, quantitative polymerase chain reaction (PCR), reverse transcription PCR to detect full-length messenger RNA (mRNA) transcripts, and in situ hybridization (ISH). GLP1R mRNA transcripts, encompassing the entire open reading frame, were detected in all four cardiac chambers from 15 hearts at levels approximating those detected in human pancreas. In contrast, cardiac GLP2R expression was relatively lower, and cardiac GCGR expression was sporadic and not detected in the left ventricle. GLP1R mRNA transcripts were not detected in RNA from human cardiac fibroblasts, coronary artery endothelial, or vascular smooth muscle cells. Human Brunner glands and pancreatic islets exhibited GLP-1R immunopositivity and abundant expression of GLP1R mRNA transcripts by ISH. GLP1R transcripts were also detected by ISH in human cardiac sinoatrial node tissue. However, definitive cellular localization of GLP1R mRNA transcripts or immunoreactive GLP-1R protein within human cardiomyocytes or cardiac blood vessels remained elusive. Moreover, validated GLP-1R antisera lacked sufficient sensitivity to detect expression of the endogenous islet or cardiac GLP-1R by Western blotting. Hence, although human cardiac ventricles express the GLP1R, the identity of one or more ventricular cell type(s) that express a translated GLP1R protein requires further clarification with highly sensitive methods of detection.

PMID- 29444225 TI - Association of Neighborhood Socioeconomic Status With Risk of Infection and Sepsis. AB - Background: Prior studies suggest disparities in sepsis risk and outcomes based on place of residence. We sought to examine the association between neighborhood socioeconomic status (nSES) and hospitalization for infection and sepsis. Methods: We conducted a prospective cohort study using data from 30239 participants in the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study. nSES was defined using a score derived from census data and classified into quartiles. Infection and sepsis hospitalizations were identified over the period 2003-2012. We fit Cox proportional hazards models, reporting hazard ratios (HRs) with 95% confidence intervals (CIs) and examining mediation by participant characteristics. Results: Over a median follow-up of 6.5 years, there were 3054 hospitalizations for serious infection. Infection incidence was lower for participants in the highest nSES quartile compared with the lowest quartile (11.7 vs 15.6 per 1000 person-years). After adjustment for demographics, comorbidities, and functional status, infection hazards were also lower for the highest quartile (HR, 0.84 [95% CI, .73-.97]), with a linear trend (P = .011). However, there was no association between nSES and sepsis at presentation among those hospitalized with infection. Physical weakness, income, and diabetes had modest mediating effects on the association of nSES with infection. Conclusions: Our study shows that differential infection risk may explain nSES disparities in sepsis incidence, as higher nSES is associated with lower infection hospitalization rates, but there is no association with sepsis among those hospitalized. Mediation analysis showed that nSES may influence infection hospitalization risk at least partially through physical weakness, individual income, and comorbid diabetes. PMID- 29444227 TI - The Ross-Konno procedure in neonates and infants less than 3 months of age. AB - OBJECTIVES: Patients with severe left ventricular outflow tract obstruction often suffer from impaired left ventricular function, endocardial fibroelastosis and borderline-sized structures. The early Ross-Konno operation can offer complete repair due to outflow tract stenosis and enable the functional recovery and growth of small structures. METHODS: Between 2008 and March 2017, 44 early Ross Konno procedures were performed at our centre. Thirty-five patients were neonates, and 9 were infants less than 3 months of age. A retrospective single centre investigation was carried out analysing early and late deaths, postoperative complications and reoperations during the follow-up period. Potential prognostic influence factors as previous fetal intervention, associated lesions as presence of a VSD or hypoplastic aortic arch or severe endocardial fibroelastosis were examined. RESULTS: The in-hospital mortality rate was 7% (3 of 44), and the late mortality rate was 2%. There were no deaths in the group with ventricular septal defects (9 cases), and there was 1 death in the group with critical aortic stenosis without arch repair (1 of 24; 4%). The most deaths occurred in patients with critical aortic stenosis and aortic arch repair (3 of 11; 27%) (P = 0.012). Fifteen patients with foetal intervention had a mid-term survival rate of 87%. Reoperations were necessary in 19 of 40 surviving patients during a mean follow-up period of 5.9 years. CONCLUSIONS: The early Ross-Konno procedure can enable biventricular repair even in borderline left ventricles with good long-term outcome. Thus far, there were no reoperations at the level of the autograft or the left ventricular outflow tract in our cohort. The highest operative risk was observed in patients with critical aortic stenosis and aortic arch hypoplasia. PMID- 29444228 TI - Towards optimal electronic medical record use: perspectives of advanced users. AB - Background: While primary health care electronic medical record (EMR) adoption has increased in Canada, the use of advanced EMR features is limited. Realizing the potential benefits of primary health care EMR use is dependent not only on EMR acquisition, but also on its comprehensive use and integration into practice; yet, little is known about the advanced use of EMRs in primary health care. Objective: To explore the views of advanced primary health care EMR users practising in a team-based environment. Methods: A descriptive qualitative approach was used to explore the views of primary health care practitioners who were identified as advanced EMR users. Twelve individual semi-structured interviews were held with primary health care practitioners in Southwestern Ontario, Canada. Field notes were created after each interview. Interviews were audio recorded and transcribed verbatim. Researchers independently coded the transcripts and then met to discuss the results of the coding. We used a thematic approach to data analysis. Results: Three themes emerged from the data analysis: advanced EMR users as individuals with signature characteristics, advanced EMR users as visionaries and advanced EMR users as agents of change. In any one participant, these elements could overlap, illuminating the important interplay between these themes. Taken together, these themes defined advanced use among this group of primary health care practitioners. Conclusions: To realize the potential benefits of EMR use in improved patient care and outcomes, we need to understand how to support EMR use. This study provides a necessary building block in furthering this understanding. PMID- 29444229 TI - Bioprosthetic mitral valve replacement in patients aged 65 years or younger: long term outcomes with the Carpentier-Edwards PERIMOUNT pericardial valve. AB - OBJECTIVES: Mitral valve replacement using a bioprosthesis remains controversial in young patients because data on long-term outcomes are missing. This study evaluated the long-term results of the PERIMOUNT pericardial mitral bioprosthesis in patients aged 65 years or younger. METHODS: From 1984 to 2010, 148 Carpentier Edwards PERIMOUNT mitral bioprostheses were implanted in 148 patients aged 65 years or younger. Baseline clinical, perioperative and follow-up data were recorded prospectively. Structural valve deterioration (SVD) was defined by strict echocardiographic assessment. RESULTS: The mean follow-up period was 8.6 +/- 5.5 years, for a total of 1269 valve-years. Operative mortality rate was 2.0%. Fifty-one late deaths occurred (linearized rate 4.0% per valve-year). Actuarial survival rates averaged 70 +/- 4%, 53 +/- 6% and 31 +/- 7% after 10, 15 and 20 years of follow-up, respectively. Actuarial freedom from SVD at 10, 15 and 20 years was 78 +/- 5%, 47 +/- 7% and 19 +/- 7%, respectively. Reoperation was associated with no operative mortality. Actuarial freedom from reoperation due to SVD at 10, 15 and 20 years was 82 +/- 4%, 50 +/- 6% and 25 +/- 8%, respectively. Competing risk analysis demonstrated an actual risk of explantation secondary to SVD at 20 years of 44 +/- 5%. Expected valve durability was 14.2 years for this age group. CONCLUSIONS: In the selected patients aged 65 years or younger undergoing mitral valve replacement with a pericardial bioprosthesis, the expected valve durability was 14.2 years. Reoperation for SVD was associated with a low risk of mortality. PMID- 29444230 TI - Social movement involvement and healthy diet and activity behaviors among US adults. AB - Unhealthy lifestyle behaviors, namely poor diet and inadequate physical activity, significantly contribute to poor health and obesity risk, which in turn impact chronic illness outcomes. A possible approach to improving these health behaviors and subsequent outcomes is to capitalize on the theorized link between social movement involvement and overlapping health behaviors. Social movement involvement may be a viable stealth intervention for health, utilizing intrinsic motivators to improve health without an explicit focus on changing health behavior. Thus, the current study explored the links between social movement involvement and diet and physical activity. Two samples from a college population (N = 196) and the general population (N = 195) participated in an online survey, which included measures of social movement involvement, social movement-related health behaviors and dietary intake and physical activity. After controlling for known covariates, social movement-related health behaviors mediated the relationship between level of social movement involvement and fruit and vegetable consumption, whole grain intake and average daily physical activity in both samples. These findings suggest that health behaviors associated with social movement involvement may be an important mechanism in promoting health among social movement members and that the model holds across adult populations. This research adds to existing literature on stealth interventions as a viable means of improving important behavioral health components linked with obesity and chronic disease and supports social movement involvement as a potential form of stealth intervention. PMID- 29444231 TI - Phase IIa study of the CD19 antibody MOR208 in patients with relapsed or refractory B-cell non-Hodgkin's lymphoma. AB - Background: This two-stage, phase IIa study investigated the antitumor activity and safety of MOR208, an Fc-engineered, humanized, CD19 antibody, in patients with relapsed or refractory (R-R) B-cell non-Hodgkin's lymphoma (NHL). CD19 is broadly expressed across the B-lymphocyte lineage, including in B-cell malignancies, but not by hematological stem cells. Patients and methods: Patients aged >=18 years, with R-R NHL progressing after >=1 prior rituximab-containing regimen were enrolled into subtype-specific cohorts: diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL), other indolent (i)NHL and mantle cell lymphoma (MCL). Treatment was MOR208, 12 mg/kg intravenously, weekly, for 8 weeks. Patients with at least stable disease could continue treatment for an additional 4 weeks. Those with a partial or complete response after 12 weeks could receive extended MOR208 treatment (12 mg/kg, either monthly or every second week) until progression. The primary end point was overall response rate. Results: Ninety-two patients were enrolled: DLBCL (n = 35), FL (n = 34), other iNHL (n = 11) and MCL (n = 12). Responses were observed in DLBCL, FL and other iNHL cohorts (26%, 29% and 27%, respectively). They lasted >=12 months in 5/9 responding patients with DLBCL, 4/9 with FL and 2/3 with other iNHL. Responses in nine patients are ongoing (>26 months in five instances). Patients with rituximab refractory disease showed a similar response rate and progression-free survival time to patients with non-refractory disease. The most common adverse events (any grade) were infusion-related reactions (12%) and neutropenia (12%). One patient experienced a grade 4 infusion-related reaction and eight patients (9%) experienced grade 3/4 neutropenia. No treatment-related deaths were reported. Conclusions: MOR208 monotherapy demonstrated promising clinical activity in patients with R-R DLBCL and R-R FL, including in patients with rituximab refractory tumors. These efficacy data and the favorable safety profile support further investigation of MOR208 in phase II/III combination therapy trials in R-R DLBCL. ClinicalTrials.gov number: NCT01685008. PMID- 29444232 TI - HiCapTools: a software suite for probe design and proximity detection for targeted chromosome conformation capture applications. AB - Summary: Folding of eukaryotic genomes within nuclear space enables physical and functional contacts between regions that are otherwise kilobases away in sequence space. Targeted chromosome conformation capture methods (T2C, chi-C and HiCap) are capable of informing genomic contacts for a subset of regions targeted by probes. We here present HiCapTools, a software package that can design sequence capture probes for targeted chromosome capture applications and analyse sequencing output to detect proximities involving targeted fragments. Two probes are designed for each feature while avoiding repeat elements and non-unique regions. The data analysis suite processes alignment files to report genomic proximities for each feature at restriction fragment level and is isoform-aware for gene features. Statistical significance of contact frequencies is evaluated using an empirically derived background distribution. Targeted chromosome conformation capture applications are invaluable for locating target genes of disease-associated variants found by genome-wide association studies. Hence, we believe our software suite will prove to be useful for a wider user base within clinical and functional applications. Availability: https://github.com/sahlenlab/HiCapTools.

PMID- 29444233 TI - BetaSerpentine: a bioinformatics tool for reconstruction of amyloid structures. AB - Motivation: Numerous experimental studies have suggested that polypeptide chains of large amyloidogenic regions zig-zag in beta-serpentine arrangements. These beta-serpentines are stacked axially and form the superpleated beta-structure. Despite this progress in the understanding of amyloid folds, the determination of their 3D structure at the atomic level is still a problem due to the polymorphism of these fibrils and incompleteness of experimental structural data. Today, the way to get insight into the atomic structure of amyloids is a combination of experimental studies with bioinformatics. Results: We developed a computer program BetaSerpentine that reconstructs beta-serpentine arrangements from individual beta-arches predicted by ArchCandy program and ranks them in order of preference. It was shown that the BetaSerpentine program in combination with the experimental data can be used to gain insight into the detailed 3D structure of amyloids. It opens avenues to the structure-based interpretation and design of the experiments.

PMID- 29444234 TI - ThreaDNA: predicting DNA mechanics' contribution to sequence selectivity of proteins along whole genomes. AB - Motivation: Many DNA-binding proteins recognize their target sequences indirectly, by sensing DNA's response to mechanical distortion. ThreaDNA estimates this response based on high-resolution structures of the protein-DNA complex of interest. Implementing an efficient nanoscale modeling of DNA deformations involving essentially no adjustable parameters, it returns the profile of deformation energy along whole genomes, at base-pair resolution, within minutes on usual laptop/desktop computers. Our predictions can also be easily combined with estimations of direct selectivity through a generalized form of position-weight-matrices. The formalism of ThreaDNA is accessible to a wide audience. Results: We demonstrate the importance of indirect readout for the nucleosome as well as the bacterial regulators Fis and CRP. Combined with the direct contribution provided by usual sequence motifs, it significantly improves the prediction of sequence selectivity, and allows quantifying the two distinct physical mechanisms underlying it.

PMID- 29444235 TI - Squeakr: an exact and approximate k-mer counting system. AB - Motivation: k-mer-based algorithms have become increasingly popular in the processing of high-throughput sequencing data. These algorithms span the gamut of the analysis pipeline from k-mer counting (e.g. for estimating assembly parameters), to error correction, genome and transcriptome assembly, and even transcript quantification. Yet, these tasks often use very different k-mer representations and data structures. In this article, we show how to build a k mer-counting and multiset-representation system using the counting quotient filter, a feature-rich approximate membership query data structure. We introduce the k-mer-counting/querying system Squeakr (Simple Quotient filter-based Exact and Approximate Kmer Representation), which is based on the counting quotient filter. This off-the-shelf data structure turns out to be an efficient (approximate or exact) representation for sets or multisets of k-mers. Results: Squeakr takes 2*-4.3* less time than the state-of-the-art to count and perform a random-point-query workload. Squeakr is memory-efficient, consuming 1.5*-4.3* less memory than the state-of-the-art. It offers competitive counting performance. In fact, it is faster for larger k-mers, and answers point queries (i.e. queries for the abundance of a particular k-mer) over an order-of-magnitude faster than other systems. The Squeakr representation of the k-mer multiset turns out to be immediately useful for downstream processing (e.g. de Bruijn graph traversal) because it supports fast queries and dynamic k-mer insertion, deletion, and modification.

PMID- 29444236 TI - findGSE: estimating genome size variation within human and Arabidopsis using k mer frequencies. AB - Motivation: Analyzing k-mer frequencies in whole-genome sequencing data is becoming a common method for estimating genome size (GS). However, it remains uninvestigated how accurate the method is, especially if it can capture intra species GS variation. Results: We present findGSE, which fits skew normal distributions to k-mer frequencies to estimate GS. findGSE outperformed existing tools in an extensive simulation study. Estimating GSs of 89 Arabidopsis thaliana accessions, findGSE showed the highest capability in capturing GS variations. In an application with 71 female and 71 male human individuals, findGSE delivered an average of 3039 Mb as haploid human GS, while female genomes were on average 41 Mb larger than male genomes, in astonishing agreement with size difference of the X and Y chromosomes. Further analysis showed that human GS variations link to geographical patterns and significant differences between populations, which can be explained by variable abundances of LINE-1 retrotransposons.

AB - Motivation: New Generation Sequencing (NGS) technologies for genome sequencing produce large amounts of short genomic reads per experiment, which are highly redundant and compressible. However, general-purpose compressors are unable to exploit this redundancy due to the special structure present in the data. Results: We present a new algorithm for compressing reads both with and without preserving the read order. In both cases, it achieves 1.4*-2* compression gain over state-of-the-art read compression tools for datasets containing as many as 3 billion Illumina reads. Our tool is based on the idea of approximately reordering the reads according to their position in the genome using hashed substring indices. We also present a systematic analysis of the read compression problem and compute bounds on fundamental limits of read compression. This analysis sheds light on the dynamics of the proposed algorithm (and read compression algorithms in general) and helps understand its performance in practice. The algorithm compresses only the read sequence, works with unaligned FASTQ files, and does not require a reference. Contact: schandak@stanford.edu.

PMID- 29444238 TI - Vitamin D receptor restricts T helper 2-biased inflammation in the heart. AB - Background and aims: The aberrant immune responses play a critical role in the pathogenesis of myocarditis. Vitamin D receptor (VDR) has immune regulatory functions. This study aims to investigate the role of VDR in restricting the immune inflammation in the heart. Methods and results: The human heart samples were obtained from the heart transplantation. T helper (Th)2 and Th1 responses in the heart tissue were characterized by histology and immune assay. VDR-/- mice and recombination activating gene 2-/- mice were used in the experiments to test the role of VDR in maintaining the homeostasis in the heart. The results showed that, besides tissue damage, lower expression of VDR, high frequency of Th2 cells and increase in Th2 cytokines in the hearts of patients with myocarditis at the end stage of heart failure. The spontaneous Th2-biased inflammation was observed in the hearts of VDR-/- mice. CD4+ T cells from the VDR-/- mouse hearts were at highly activating status. The naive VDR-/- CD4+ T cells and naive CD4+ T cells from human hearts with myocarditis were prone to differentiate into Th2 cells. VDR formed complexes with GATA3, the interleukin (IL)-4 transcription factor, to prevent the Il4 gene transcription. Transplantation with VDR-/-CD4+ T cells induced the Th2-biased inflammation in the hearts of Rag2-/- mice. Reconstitution of VDR in CD4+ T cells inhibited the Th2-biased inflammation in the heart. Conclusions: VDR-deficiency contributes to the pathogenesis of myocarditis. To enhance the VDR expression in CD4+, T cells haves the therapeutic potential for the treatment of myocarditis.

AB - See Moon and Bradbury (doi:10.1093/brain/awy067) for a scientific commentary on this article.Many hundreds of thousands of people around the world are living with the long-term consequences of spinal cord injury and they need effective new therapies. Laboratory research in experimental animals has identified a large number of potentially translatable interventions but transition to the clinic is not straightforward. Further evidence of efficacy in more clinically-relevant lesions is required to gain sufficient confidence to commence human clinical trials. Of the many therapeutic candidates currently available, intraspinally applied chondroitinase ABC has particularly well documented efficacy in experimental animals. In this study we measured the effects of this intervention in a double-blinded randomized controlled trial in a cohort of dogs with naturally-occurring severe chronic spinal cord injuries that model the condition in humans. First, we collected baseline data on a series of outcomes: forelimb hindlimb coordination (the prespecified primary outcome measure), skin sensitivity along the back, somatosensory evoked and transcranial magnetic motor evoked potentials and cystometry in 60 dogs with thoracolumbar lesions. Dogs were then randomized 1:1 to receive intraspinal injections of heat-stabilized, lipid microtube-embedded chondroitinase ABC or sham injections consisting of needle puncture of the skin. Outcome data were measured at 1, 3 and 6 months after intervention; skin sensitivity was also measured 24 h after injection (or sham). Forelimb-hindlimb coordination was affected by neither time nor chondroitinase treatment alone but there was a significant interaction between these variables such that coordination between forelimb and hindlimb stepping improved during the 6-month follow-up period in the chondroitinase-treated animals by a mean of 23%, but did not change in controls. Three dogs (10%) in the chondroitinase group also recovered the ability to ambulate without assistance. Sensitivity of the dorsal skin increased at 24 h after intervention in both groups but subsequently decreased to normal levels. Cystometry identified a non-significant improvement of bladder compliance at 1 month in the chondroitinase-injected dogs but this did not persist. There were no overall differences between groups in detection of sensory evoked potentials. Our results strongly support a beneficial effect of intraspinal injection of chondroitinase ABC on spinal cord function in this highly clinically-relevant model of chronic severe spinal cord injury. There was no evidence of long-term adverse effects associated with this intervention. We therefore conclude that this study provides strong evidence in support of initiation of clinical trials of chondroitinase ABC in humans with chronic spinal cord injury.

AB - Due to the growing public health and tourism awareness, Cimex hemipterus Fabricius (Hemiptera: Cimicidae) has gained a great interest in increasing reported infestation cases in tropical regions of the world, including Malaysia. Since the information on the molecular ecology and population biology of this species are tremendously lacking, the isolation and development of molecular markers can be used to determine its genetic structure. In this study, novel microsatellite primers isolated from enriched genomic libraries of C. hemipterus were developed using 454 Roche shotgun sequencing. Seven validated polymorphic microsatellite primers were consistently amplified and characterized from 70 tropical bed bugs collected from seven locations throughout Malaysia. The number of alleles per locus identified ranged from 6 to 14. Comparison of loci for overall and between population were done with mean observed and expected heterozygosity were determined at 0.320 and 0.814, 0.320 and 0.727, respectively. Polymorphic information criteria (PIC) valued the markers as highly informative as PIC >0.5. Overall population, they are possibly in Hardy-Weinberg equilibrium with loci Ch_09ttn, Ch_01dn, and Ch_13dn showing signs of a null allele. There were no scoring errors caused by stutter peaks, no large allele dropout was detected for all loci and showed no evidence of linkage disequilibrium. In conclusion, all seven molecular microsatellite markers identified can be beneficially used to gain more information on the population genetic structure and breeding patterns of C. hemipterus as well as the relationship of dispersal and infestation. PMID- 29444241 TI - Macro-environmental factors and physical activity in 28 European Union countries. AB - Data from the representative 2013 Eurobarometer survey were combined with macro environmental data to assess relationships with different domains of physical activity (PA) in 28 European Union countries. Higher mean annual temperatures were the only macro-environmental factor found to be associated with levels of physical activity; an increase in the mean annual temperature by 1 degrees C was associated with-0.94 fewer minutes of vigorous-intensity activity per week (95% CI: -1.66 to -0.23). This highlights the importance of modifiable influences (e.g. opportunities for active travel) on PA and underscores the potential of public health interventions to raise levels of physical activity. PMID- 29444242 TI - In vitro activity of zoliflodacin (ETX0914) against macrolide-resistant, fluoroquinolone-resistant and antimicrobial-susceptible Mycoplasma genitalium strains. AB - Background: Mycoplasma genitalium is estimated to be the second most common cause of bacterial sexually transmitted infection in Europe. It is of increasing public health concern due to the rapid development of resistance to different antimicrobial classes, including the preferred first- and second-line treatments azithromycin and moxifloxacin. Thus, new antimicrobial agents are urgently needed, especially for the treatment of MDR strains. Methods: The in vitro activity of the new spiropyrimidinetrione zoliflodacin against 47 M. genitalium strains was assessed by growing M. genitalium in Vero cell culture and measuring growth by quantitative PCR. The collection included 34 moxifloxacin-susceptible (MIC <1 mg/L) and 13 moxifloxacin-resistant (MIC >=1 mg/L) strains. Twenty-three of the strains were azithromycin resistant (MIC >=16 mg/L) and 12 of these strains were MDR. Results: Only one (2.1%) strain with substantially increased MIC (4 mg/L) and potential resistance to zoliflodacin was found. Zoliflodacin was overall more potent than moxifloxacin (P = 0.009) and no cross-resistance was observed between the two drug classes of topoisomerase II inhibitors. Differences in the MICs of zoliflodacin and azithromycin were not statistically significant; however, 23 (48.9%) compared with potentially 1 (2.1%) of the strains were resistant to azithromycin and zoliflodacin, respectively. Conclusions: Zoliflodacin is a promising candidate for the treatment of M. genitalium and it is important to further develop and evaluate this drug.

AB - Clinical pharmacogenomics (PGx) has the potential to make pharmacotherapy safer and more effective by utilizing genetic patient data for drug dosing and selection. However, widespread adoption of PGx depends on its successful integration into routine clinical care through clinical decision support tools, which is often hampered by insufficient or fragmented infrastructures. This paper describes the setup and implementation of a unique multimodal, multilingual clinical decision support intervention consisting of digital, paper-, and mobile based tools that are deployed across implementation sites in seven European countries participating in the Ubiquitous PGx (U-PGx) project. PMID- 29444244 TI - Acute Toxicity of Permethrin, Deltamethrin, and Etofenprox to the Alfalfa Leafcutting Bee. AB - Current regulatory requirements for insecticide toxicity to nontarget insects focus on the honey bee, Apis mellifera (L.; Hymenoptera: Apidae), but this species cannot represent all insect pollinator species in terms of response to insecticides. Therefore, we characterized the toxicity of pyrethroid insecticides used for adult mosquito management (permethrin, deltamethrin, and etofenprox) on a nontarget insect, the adult alfalfa leafcutting bee, Megachile rotundata (F.; Hymenoptera: Megachilidae) in two separate studies. In the first study, the doses causing 50 and 90% mortality (LD50 and LD90, respectively) were used as endpoints and 2-d-old adult females were exposed to eight concentrations ranging from 0.0075 to 0.076 MUg/bee for permethrin and etofenprox, and 0.0013-0.0075 MUg/bee for deltamethrin. For the second study, respiration rates of female M. rotundata were also recorded for 2 h after bees were dosed at the LD50 values to give an indication of stress response. Results indicated a relatively similar LD50 for permethrin and etofenprox, 0.057 and 0.051 MUg/bee, respectively, and a more toxic response, 0.0016 MUg/bee for deltamethrin. Comparatively, female A. mellifera workers have a LD50 value of 0.024 MUg/bee for permethrin and 0.015 MUg/bee for etofenprox indicating that female M. rotundata are less susceptible to topical doses of these insecticides, except for deltamethrin, where both A. mellifera and M. rotundata have an identical LD50 of 0.0016 MUg/bee. Respiration rates comparing each active ingredient to control groups, as well as rates between each active ingredient, were statistically different (P < 0.0001). The addition of these results to existing information on A. mellifera may provide more insights on how other economically beneficial and nontarget bees respond to pyrethroids.

PMID- 29444248 TI - Comparative studies on the activities of collagenases from Grimontia hollisae and Clostridium hystoliticum in the hydrolysis of synthetic substrates. AB - The collagenase produced by a gram-negative bacterium Grimontia hollisae strain 1706B (Ghcol) degrades collagen more efficiently than that produced by a gram positive bacterium Clostridium histolyticum (Chcol), which is currently the most widely used collagenase in industry [Teramura et al. (Cloning of a novel collagenase gene from the gram-negative bacterium Grimotia (Vibrio) hollisae 1706B and its efficient expression in Brevibacillus choshinensis. J Bacteriol 2011;193:3049-3056)]. Here, we compared the Ghcol and Chcol activities using two synthetic substrates. In the hydrolysis of (7-methoxycoumarin-4-yl)acetyl-L-Lys-L Pro-L-Leu-Gly-L-Leu-[N3-(2, 4-dinitrophenyl)-L-2, 3-diaminopropioyl]-L-Ala-L-Arg NH2, Ghcol exhibited 350-fold higher activity than Chcol in the absence of CaCl2 and NaCl. The Ghcol activity markedly decreased with increasing concentrations of buffer, CaCl2 or NaCl, while the Chcol activity did not, suggesting that the Ghcol activity was sensitive to solvent components. In the hydrolysis of N-[3-(2 furyl)acryloyl]-L-Leu-Gly-L-Pro-Ala, Ghcol exhibited 16-fold higher activity than Chcol in the absence of CaCl2 and NaCl, and both enzyme activities did not decrease with increasing concentrations of buffer, CaCl2 or NaCl. pH dependences of activity revealed that the ionizable group responsible for acidic pKe may be Glu for Ghcol and Chcol, while that for alkaline pKe may be His for Ghcol and Tyr for Chcol. These striking differences suggest that the catalytic mechanism of Ghcol might be considerably different from that of clostridial collagenases. PMID- 29444249 TI - Improvements scale-up and rapid response systems in the hospitals. PMID- 29444250 TI - Are elevated serum haemolysis markers a harbinger of adverse events in HeartMate II patients? AB - OBJECTIVES: Haemolysis during left ventricular assist device support is associated with thrombosis. In this retrospective study, we analysed whether low level haemolysis (LLH) as defined by simultaneously elevated lactate dehydrogenase (LDH) and free haemoglobin (fHb) levels had an impact on thromboembolic and bleeding events and on von Willebrand factor levels in HeartMate II patients. METHODS: After exclusion of patients with LDH >700 U/l and fHb >40 mg/dl at hospital discharge, 79 HeartMate II patients were included. LDH and fHb levels were measured at discharge and in 3 months interval. von Willebrand factor activity and antigen activity were measured 3 months postoperatively. Outcomes regarding ischaemic stroke (IS), pump thrombosis (PT) and gastrointestinal bleeding were recorded. Patients with LLH (400 < LDH <= 700 U/l and 30 < fHb <= 40 mg/dl) at discharge (pre-Hemolyzers) were compared with the rest of the cohort (non-Hemolyzers). Competing risk analysis and Cox regression were applied for the comparison between groups. RESULTS: In all, 20% of the patients were identified as pre-Hemolyzers. Of these, 5 patients had PT and 3 patients had IS compared with 2 PT and 2 IS in the non-Hemolyzers group (P = 0.003 and P = 0.053, respectively). Fifty percent of the pre-Hemolyzers suffered gastrointestinal bleeding compared with 42% of the non-Hemolyzers (P = 0.399). The cumulative risk of thromboembolic events (IS or PT) in the pre Hemolyzers group was significantly higher compared with the non-Hemolyzers group (hazard ratio 11.8, 95% confidence interval 3.7-37.7; P = 0.005). LLH did not have an impact on von Willebrand factor and the incidence of gastrointestinal bleeding. CONCLUSIONS: LLH as assessed by elevated fHb and LDH values at discharge during HeartMate II support is associated with thromboembolic events. PMID- 29444251 TI - Cultured equine satellite cells as a model system to assess leucine stimulated protein synthesis in horse muscle. AB - Leucine has been shown to stimulate the mammalian/mechanistic target of rapamycin (mTOR) signaling pathway which plays numerous key regulatory roles in cell growth, survival, and metabolism including protein synthesis in a number of species. However, previous work with equine satellite cells has suggested distinct species differences in regards to physiological effects and the magnitude of responses to growth factors and regulators. Because there is limited research available regarding the role of leucine in regulating equine skeletal muscle protein synthesis, the objective of this study was to evaluate the effect of leucine on the mTOR signaling pathway in cultured equine satellite. Protein synthesis was evaluated by measuring the incorporation of [3H] Phenylalanine (3HPhe) in equine satellite cell myotube cultures treated with a leucine titration ranging from 0 to 408 uM. Our results show a 1.8-fold increase (P < 0.02) in protein synthesis at levels slightly greater than those found in the general circulation, 204 and 408 uM when compared to a no leucine control (0 uM). Puromycin incorporation, a nonradioactive surface sensing of translation (SUnSET) methodology, was also measured in cells treated with leucine (LEU; 408 uM), a no leucine control (CON), and a puromycin-negative vehicle (PURO-). These results demonstrated a 180% increase (P = 0.0056) in puromycin incorporation in LEU compared to CON cultures. To evaluate the mTOR signaling pathway, equine satellite cell myotube cultures were treated with leucine (LEU; 408 uM) or a no leucine control (CON) in the presence or absence of rapamycin (LR and CR, respectively), an inhibitor of mTOR. The mTOR inhibitor, rapamycin, suppressed phosphorylation of mTOR (P < 0.01) and rS6 (P < 0.01) with an increase in phosphorylation of rS6 in leucine-treated cultures observed when compared to control cultures (P < 0.05). Similarly, there was a 27% increase (P < 0.005) in the hyperphosphorylated gamma-form of 4E-BP1 compared to total 4E-BP1 in LEU compared to CON cultures with leucine-induced phosphorylation of 4E-BP1 completely blocked by rapamycin with a smaller decrease observed in CR compared to CON cultures. The major finding of this study was that leucine activated the mTOR translation initiation pathway and increased transcription of global proteins in cultured equine satellite cells. Use of the cell culture system with primary equine muscle cell lines provides the opportunity to distinguish the impact of leucine on muscle and protein synthesis, independent of systemic interactions.

AB - Objectives: To evaluate the diagnostic performance of the Vela next-generation sequencing (NGS) system in conjunction with the Sentosa SQ HIV Genotyping Assay for genotyping HIV-1. Methods: Plasma RNA was extracted and templates prepared with the Sentosa SX instrument before sequencing the HIV-1 polymerase on the Sentosa SQ301 Sequencer (PGM IonTorrent). The Vela NGS System was compared with direct sequencing and the 454 GS-FLX (Roche) and MiSeq (Illumina) systems for genotypic resistance testing on clinical samples. Results: The Vela NGS system detected majority resistance mutations in subtype B and CRF02-AG samples at 500 copies/mL and minority variants with a sensitivity of 5% at 100 000 copies/mL. The Vela NGS system and direct sequencing identified resistance mutations with 97% concordance in 46 clinical samples. Vela identified 1/20 of the 1%-5% mutations identified by 454, 5/12 of the 5%-20% mutations and 60/61 of the >20% mutations. Vela identified 3/14 of the 1%-5% mutations identified by MiSeq, 0/2 of the 5%-20% mutations and 47/47 of the >20% mutations. The resistance mutation quantifications by Vela and 454 were concordant (bias: 2.31%), as were those by Vela and MiSeq (bias: 1.06%). Conclusions: The Vela NGS system provides automated nucleic acid extraction, PCR reagent distribution, library preparation and bioinformatics analysis. The analytical performance was very good when compared with direct sequencing, but was less sensitive than two other NGS platforms for detecting minority variants. PMID- 29444252 TI - Human Striatal Response to Reward Anticipation Linked to Hippocampal Glutamate Levels. AB - Background: Dysfunctional reward processing is associated with a number of psychiatric disorders, such as addiction and schizophrenia. It is thought that reward is regulated mainly by dopamine transmission in the ventral striatum. Contemporary animal models suggest that striatal dopamine concentrations and associated behaviors are related to glutamatergic functioning in the ventral hippocampus. However, in humans the association between reward-related ventral striatal response and hippocampal glutamate levels is unclear. Methods: Nineteen healthy participants were studied using proton magnetic resonance spectroscopy to measure hippocampal glutamate levels, and functional magnetic resonance imaging to assess striatal activation and functional connectivity during performance of a monetary incentive delay task. Results: We found that ventral striatal activation related to reward processing was correlated with hippocampal glutamate levels. In addition, context-dependent functional coupling was demonstrated between the ventral striatum and both the lingual gyrus and hippocampus during reward anticipation. Elevated hippocampal glutamate levels were inversely related to context-dependent functional connectivity between the ventral striatum and the anterior hippocampus while anticipating reward. Conclusions: These findings indicate that human striatal responses to reward are influenced by hippocampal glutamate levels. This may be relevant for psychiatric disorders associated with abnormal reward processing such as addiction and schizophrenia. PMID- 29444254 TI - High-resolution esophageal manometry in a Mexican population: diagnostic outcome. AB - High-resolution esophageal manometry (HREM) has become the method of choice for evaluation of esophageal motility disorders. There is a paucity of data with this technique from Hispanic countries. This study aims to characterize the diagnostic outcome of HREM in a large cohort of consecutive patients in Mexico.This study was conducted in Monterrey, Mexico from March 1, 2013 to March 31, 2015. Our diverse study population included patients from a major academic institution and the community. HREM was done applying the Chicago Classification 3. Diagnostic outcome was grouped as weak peristaltic disorders, gastroesophageal junction disorders, and hypertensive/uncoordinated peristalsis.We studied 670 consecutive patients, 57% were women, mean age was 43.8 years. The majority (465 [69%]) were referred for preoperative evaluation of gastroesophageal reflux disease (GERD), 365 (78%) of whom had a normal study. Overall, 193 (29%) patients had abnormal motility, the most common disorder being weak peristalsis (104 [54%]). In patients with dysphagia, the most frequent finding was achalasia (23/46 [50%]).To our knowledge, this is the first study to characterize the diagnostic outcome of HREM in a large cohort of Hispanic patients in Latin America. At our open access center, 69% of patients were referred for preoperative evaluation of GERD, reflecting the popularity of antireflux surgery. This study confirms the high prevalence of weak peristalsis and highlights the importance of addressing its pathophysiology and management. The finding of achalasia in 50% of our patients with dysphagia is consistent with recent reports regarding the rising incidence of this disorder and underscores the need of prompt motility testing in this population. PMID- 29444256 TI - Dose effect of patient-care team communication via secure portal messaging on glucose and blood pressure control. AB - Objectives: Organizational strategies for implementing eHealth tools influence patient and provider use of portal technology. This study examines whether the intensity of bidirectional secure portal messaging is associated with improved clinical outcomes. Material and Methods: This is a retrospective cohort analysis of 101 019 patients with diabetes or hypertension (11 138 active portal users) who received primary care within the Ochsner Health System between 2012 and 2014. Propensity score-adjusted multivariable fixed effects regression panel analysis was used to examine associations between intensity of "medical advice" portal messaging and glucose/blood pressure control. Results: Most portal users rarely used medical advice messaging. A higher proportion of patients who were age 50 years and older, female, white non-Hispanic, and with co-morbid diabetes and hypertension had higher frequency and intensity of medical advice messaging. Study findings revealed a dose-response effect of the intensity of messaging on glucose control, whereby, compared to nonportal users, each level of messaging among portal users was associated with greater decreases in HbA1c (beta estimate [95% CI]: none -0.28 (-0.34 to -0.22); low -0.28 (-0.32 to -0.24); medium -0.41 ( 0.52 to -0.31); high -0.43 (-0.60 to -0.27), all P <= .001). There was no observed effect on blood pressure. Conclusions: The digital divide exists not only between portal users and nonusers but also among portal users. Research exploring the relationship between intensity of bidirectional secure messaging and health outcomes for a broader scope of chronic conditions is needed. Future implementation research must also elucidate best practices that enhance not only the use of portals by patients and providers, but how they use portals. PMID- 29444255 TI - Identification of the DNA methyltransferases establishing the methylome of the cyanobacterium Synechocystis sp. PCC 6803. AB - DNA methylation in bacteria is important for defense against foreign DNA, but is also involved in DNA repair, replication, chromosome partitioning, and regulatory processes. Thus, characterization of the underlying DNA methyltransferases in genetically tractable bacteria is of paramount importance. Here, we characterized the methylome and orphan methyltransferases in the model cyanobacterium Synechocystis sp. PCC 6803. Single molecule real-time (SMRT) sequencing revealed four DNA methylation recognition sequences in addition to the previously known motif m5CGATCG, which is recognized by M.Ssp6803I. For three of the new recognition sequences, we identified the responsible methyltransferases. M.Ssp6803II, encoded by the sll0729 gene, modifies GGm4CC, M.Ssp6803III, encoded by slr1803, represents the cyanobacterial dam-like methyltransferase modifying Gm6ATC, and M.Ssp6803V, encoded by slr6095 on plasmid pSYSX, transfers methyl groups to the bipartite motif GGm6AN7TTGG/CCAm6AN7TCC. The remaining methylation recognition sequence GAm6AGGC is probably recognized by methyltransferase M.Ssp6803IV encoded by slr6050. M.Ssp6803III and M.Ssp6803IV were essential for the viability of Synechocystis, while the strains lacking M.Ssp6803I and M.Ssp6803V showed growth similar to the wild type. In contrast, growth was strongly diminished of the Deltasll0729 mutant lacking M.Ssp6803II. These data provide the basis for systematic studies on the molecular mechanisms impacted by these methyltransferases. PMID- 29444257 TI - Comparison of Strategies and Incidence Thresholds for Vi Conjugate Vaccines Against Typhoid Fever: A Cost-effectiveness Modeling Study. AB - Background: Typhoid fever remains a major public health problem globally. While new Vi conjugate vaccines hold promise for averting disease, the optimal programmatic delivery remains unclear. We aimed to identify the strategies and associated epidemiologic conditions under which Vi conjugate vaccines would be cost-effective. Methods: We developed a dynamic, age-structured transmission and cost-effectiveness model that simulated multiple vaccination strategies with a typhoid Vi conjugate vaccine from a societal perspective. We simulated 10-year vaccination programs with (1) routine immunization of infants (aged <1 year) through the Expanded Program on Immunization (EPI) and (2) routine immunization of infants through the EPI plus a 1-time catch-up campaign in school-aged children (aged 5-14 years). In the base case analysis, we assumed a 0.5% case fatality rate for all cases of clinically symptomatic typhoid fever and defined strategies as highly cost-effective by using the definition of a low-income country (defined as a country with a gross domestic product of $1045 per capita). We defined incidence as the true number of clinically symptomatic people in the population per year. Results: Vi conjugate typhoid vaccines were highly cost effective when administered by routine immunization activities through the EPI in settings with an annual incidence of >50 cases/100000 (95% uncertainty interval, 40-75 cases) and when administered through the EPI plus a catch-up campaign in settings with an annual incidence of >130 cases/100000 (95% uncertainty interval, 50-395 cases). The incidence threshold was sensitive to the typhoid-related case fatality rate, carrier contribution to transmission, vaccine characteristics, and country-specific economic threshold for cost-effectiveness. Conclusions: Typhoid Vi conjugate vaccines would be highly cost-effective in low-income countries in settings of moderate typhoid incidence (50 cases/100000 annually). These results were sensitive to case-fatality rates, underscoring the need to consider factors contributing to typhoid mortality (eg, healthcare access and antimicrobial resistance) in the global vaccination strategy.

PMID- 29444258 TI - Modeling the Influence of Seasonal Differences in the HPA Axis on Synchronization of the Circadian Clock and Cell Cycle. AB - Synchronization of biological functions to environmental signals enables organisms to anticipate and appropriately respond to daily external fluctuations and is critical to the maintenance of homeostasis. Misalignment of circadian rhythms with environmental cues is associated with adverse health outcomes. Cortisol, the downstream effector of hypothalamic-pituitary-adrenal (HPA) activity, facilitates synchronization of peripheral biological processes to the environment. Cortisol levels exhibit substantial seasonal rhythmicity, with peak levels occurring during the short-photoperiod winter months and reduced levels occurring in the long-photoperiod summer season. Seasonal changes in cortisol secretion could therefore alter its entraining capabilities, resulting in a season-dependent modification in the alignment of biological activities with the environment. We develop a mathematical model to investigate the influence of photoperiod-induced seasonal differences in the circadian rhythmicity of the HPA axis on the synchronization of the peripheral circadian clock and cell cycle in a heterogeneous cell population. Model simulations predict that the high-amplitude cortisol rhythms in winter result in the greatest entrainment of peripheral oscillators. Furthermore, simulations predict a circadian gating of the cell cycle with respect to the expression of peripheral clock genes. Seasonal differences in cortisol rhythmicity are also predicted to influence mitotic synchrony, with a high-amplitude winter rhythm resulting in the greatest synchrony and a shift in timing of the cell cycle phases, relative to summer. Our results highlight the primary interactions among the HPA axis, the peripheral circadian clock, and the cell cycle and thereby provide an improved understanding of the implications of circadian misalignment on the synchronization of peripheral regulatory processes. PMID- 29444261 TI - Selective Androgen Receptor Modulator S42 Suppresses Prostate Cancer Cell Proliferation. AB - We previously identified the selective androgen receptor (AR) modulator S42, which does not stimulate prostate growth but has a beneficial effect on lipid metabolism. In the prostate cancer (PC) cell line LNCaP, S42 did not induce AR transactivation but antagonized 5alpha-dihydrotestosterone (DHT)-induced AR activation. Next, we investigated whether S42 suppresses the growth of PC cell lines. Basal growth of LNCaP cells was significantly suppressed by treatment with S42 compared with vehicle, as determined by cell counting and 5-bromo-2' deoxyuridine assays. The suppressive effect of S42 on cell growth was evident in the AR-positive PC cells LNCaP and 22Rv1 and was slightly observed even in the AR negative PC-3 cells. However, S42 did not induce apoptosis as determined by the terminal deoxynucleotidyltransferase-mediated dUTP nick end labeling assay. S42 had an even greater suppressive effect on DHT-dependent LNCaP cell proliferation than on basal proliferation (P < 0.05). DHT treatment increased the expression of phosphorylated extracellular signal-regulated kinase (ERK)-mitogen-activated protein kinase (MAPK), a major signaling molecule for PC proliferation, and this was significantly inhibited by S42. DHT also significantly upregulated AR, insulinlike growth factor-1 receptor (IGF-1R), and insulin receptor (IR)-beta protein levels, which were similarly reduced by S42 treatment. Importantly, S42 administration to mice attenuated the growth of LNCaP tumors and reduced tumor expression of the prostate-specific antigen, P504S, Ki67, and phosphorylated ERK MAPK. These data suggest that S42 attenuates LNCaP tumor growth not by inducing apoptosis but by inhibiting the expression of proliferation-related receptors, including IGF-1R, IR, and AR, and by suppressing ERK-MAPK activation. S42 may thus be a feasible candidate for PC treatment. PMID- 29444262 TI - Plant Cuttings: news in Botany.

Improving its quality will reduce misclassification and allow more accurate longitudinal interpretation over time. Aims: To assess the amount by which lung function (forced expiratory volume in 1 second [FEV1] and forced vital capacity [FVC]) values will be underestimated if recommended spirometry testing guidance is not followed. Methods: Lung function was measured in a population of workers. Knowledge of the final reproducible FEV1 and FVC for each worker allowed estimation of the underestimates that would have occurred if less forced manoeuvres than recommended had been performed. Results: A total of 667 workers (661 males, mean age 43 years, range 18-66) participated. Among them, 560 (84%) achieved reproducible results for both FEV1 and FVC; 470 (84%) of these did so after three technically acceptable forced expiratory manoeuvres, a cumulative total of 533 after four, 548 after five, 557 after six, 559 after seven and 560 after eight blows. If only one (or first two) technically acceptable blow(s) had been performed, mean underestimates were calculated for FEV1 of 115.1 ml (35.4 ml) and for FVC of 143.4 ml (42.3 ml). Conclusions: In this study, reproducible spirometry was achievable in most workers. Not adhering to standards underestimates lung function by clinically significant amounts. PMID- 29444265 TI - Ice algal bloom development on the surface of the Greenland Ice Sheet. AB - It is fundamental to understand the development of Zygnematophycean (Streptophyte) micro-algal blooms within Greenland Ice Sheet (GrIS) supraglacial environments, given their potential to significantly impact both physical (melt) and chemical (carbon and nutrient cycling) surface characteristics. Here, we report on a space-for-time assessment of a GrIS ice algal bloom, achieved by sampling an ~85 km transect spanning the south-western GrIS bare ice zone during the 2016 ablation season. Cell abundances ranged from 0 to 1.6 * 104 cells ml-1, with algal biomass demonstrated to increase in surface ice with time since snow line retreat (R2 = 0.73, P < 0.05). A suite of light harvesting and photo protective pigments were quantified across transects (chlorophylls, carotenoids and phenols) and shown to increase in concert with algal biomass. Ice algal communities drove net autotrophy of surface ice, with maximal rates of net production averaging 0.52 +/- 0.04 mg C l-1 d-1, and a total accumulation of 1.306 Gg C (15.82 +/- 8.14 kg C km-2) predicted for the 2016 ablation season across an 8.24 * 104 km2 region of the GrIS. By advancing our understanding of ice algal bloom development, this study marks an important step toward projecting bloom occurrence and impacts into the future. PMID- 29444267 TI - Safety of Laser Interstitial Thermal Therapy in Patients With Pacemakers. AB - BACKGROUND AND IMPORTANCE: Laser interstitial thermal therapy (LiTT) has increasingly been used as a treatment option for medically refractory epilepsy, tumors, and radiation necrosis. The use of LiTT requires intraoperative magnetic resonance (MR) thermography. This can become an issue in patients with other implanted therapeutic devices such as pacemakers and vagal nerve stimulators due to concerns regarding increases in the specific absorption rate (SAR). This is a technical case report demonstrating a successfully and safely performed LiTT in a 1.5-T magnetic resonance imaging (MRI) in a patient with a pacemaker for mesial temporal sclerosis. CLINICAL PRESENTATION: An 83-yr-old gentleman who had an implanted cardiac pacemaker presented with medically intractable epilepsy and was confirmed to have mesial temporal sclerosis on imaging. Video electroencephalography demonstrated concordant ipsilateral seizures and semiology. He underwent LiTT for ablation of the mesial temporal lobe. This was performed with the below described protocol with a cardiology nurse monitoring the patient's cardiac condition and a physicist monitoring SAR, and MR imaging quality without any adverse events. CONCLUSION: This study reports on a protocol of cardiac and MR SAR to safely perform MR-guided LiTT in the setting of traditional pacemakers in patients who are not pacemaker dependent. PMID- 29444268 TI - Advancing Tobacco Product Warning Labels Research Methods and Theory: A Summary of a Grantee Meeting Held by the US National Cancer Institute. AB - Background: The World Health Organization's Framework Convention on Tobacco Control recommends prominent pictorial health warnings on tobacco products. To advance research methods, theory and understanding of how tobacco product warning labels (TPWLs) work, the US National Cancer Institute convened a grantee meeting. Our article describes the key insights that emerged from the meeting, situated within the context of the scientific literature. Results & Recommendations: First, presentations confirmed that large, pictorial TPWLs motivate people to try to quit and encourage smoking cessation. Second, pictorial TPWLs increase attention, knowledge, negative affect, and thinking about the warning. Third, TPWL studies have primarily used brief-exposure laboratory studies and observational studies of sustained exposure through national policy implementation, with a few randomized trials involving several weeks of exposure with generally consistent results found across study designs. Fourth, novel assessment methods include brain imaging, eye tracking and "best-worst" discrete choice experiments. To make TPWL even more effective, research is needed to confirm the mechanisms of their influence, their impact across vulnerable populations, and their effect on social media posts about tobacco products. Research is also needed on the effect of trial design choices, the predictive validity of new measurement approaches, and warning labels for non-cigarette tobacco products. Implications: To improve scientific understanding of TPWL effects, this grantee meeting summary describes emerging research methods, theory and study results. Directions for future research include examination of the mechanisms of how warning labels work across diverse tobacco products and across different populations and contexts. PMID- 29444266 TI - Fundamentals of glycogen metabolism for coaches and athletes. AB - The ability of athletes to train day after day depends in large part on adequate restoration of muscle glycogen stores, a process that requires the consumption of sufficient dietary carbohydrates and ample time. Providing effective guidance to athletes and others wishing to enhance training adaptations and improve performance requires an understanding of the normal variations in muscle glycogen content in response to training and diet; the time required for adequate restoration of glycogen stores; the influence of the amount, type, and timing of carbohydrate intake on glycogen resynthesis; and the impact of other nutrients on glycogenesis. This review highlights the practical implications of the latest research related to glycogen metabolism in physically active individuals to help sports dietitians, coaches, personal trainers, and other sports health professionals gain a fundamental understanding of glycogen metabolism, as well as related practical applications for enhancing training adaptations and preparing for competition. PMID- 29444269 TI - Association of angiotensin II type 1 receptor antibodies with graft histology, function and survival in paediatric renal transplant recipients. AB - Background: We analysed in a carefully phenotyped cohort of paediatric patients the association of serum angiotensin II type 1 receptor antibodies (AT1R-Ab) with specific histological lesions and with graft function and survival in conjunction with overall and complement-binding donor-specific human leucocyte antigen donor specific antibodies (HLA-DSA). Methods: Sera of 62 patients at the time of renal graft biopsy for clinical indication >1 year post-transplant were assessed for AT1R-Ab by enzyme-linked immunosorbent assay (ELISA) and for DSA and C1q-fixing DSA by single-antigen bead technology. Results: Serum AT1R-Ab concentration was significantly higher in antibody-mediated rejection (ABMR) than in T-cell mediated rejection or control. By receiver operating characteristic (ROC) curve analysis, the optimal AT1R-Ab cut-off value discriminating between patients with features of ABMR and those without was 9.5 U/mL. A total of 6 of 28 patients (21.4%) with ABMR were only positive for AT1R-Ab. Patients with AT1R-Ab and HLA DSA double positivity had a significantly higher vascular micro-inflammation score than DSA-negative patients. The 5-year graft survival was only 59% in the AT1R-Ab-positive group compared with 87% in the AT1R-Ab-negative group. Patients with AT1R-Ab and HLA-DSA double positivity tended to have a more rapid decline of estimated glomerular filtration rate (eGFR) than patients who were only positive for AT1R-Ab or HLA-DSA. In a multivariate Cox regression model of non-invasive factors, C1q-positive HLA-DSA, eGFR and AT1R-Ab positivity were significantly associated with accelerated graft function decline. Conclusions: Serum AT1R-Ab positivity in the context of an indication biopsy >1 year post-transplant is associated with the histopathology of ABMR and is an independent non-invasive risk factor for adverse graft outcome. PMID- 29444270 TI - Efficacy and Outcomes of Posterior Inferior Cerebellar Artery (PICA) Bypass for Proximal PICA and Vertebral Artery-PICA Aneurysms: A Case Series. AB - BACKGROUND: Nonsaccular vertebral artery (VA) and posterior inferior cerebellar artery (PICA) aneurysms have high morbidity and mortality rates and are difficult to treat using standard microsurgical or endovascular techniques. Definitive revascularization can require clip trapping and/or vessel sacrifice, with PICA bypass. The published surgical experience with these approaches is limited. We herein review our recent surgical experience with PICA revascularization for complex PICA and VA/PICA aneurysms. OBJECTIVE: To determine the efficacy and outcomes of PICA bypass for revascularization of nonsaccular PICA and VA/PICA aneurysms. METHODS: Retrospective analysis of an institutional review board approved, prospective database was performed to identify patients with PICA and VA/PICA aneurysms treated with PICA bypass at a single institution. Demographic information, aneurysm characteristics, temporary clip time, and neurological outcomes were recorded. RESULTS: Ten cases of PICA revascularization were performed for both ruptured (n = 8) and unruptured (n = 2) nonsaccular proximal PICA or VA/PICA aneurysms. Seven cases were performed without vessel grafts; 3 cases required harvest of the descending branch of the lateral femoral circumflex artery. Mean temporary clip time was 38 min (range 27-50 min). Good outcomes (Glasgow Outcomes Scale score of 5) were achieved in 70% (n = 7) of patients at time of discharge; the remaining patients had a Glasgow Outcomes Scale of 3. Two bypass-related complications occurred in this series; a hematoma at the graft harvest site requiring evacuation, and severe bypass graft spasm requiring multiple endovascular treatments. CONCLUSION: PICA bypass can be a safe, effective, and highly customizable tool for the revascularization of patients with nonsaccular proximal PICA and VA/PICA aneurysms.

AB - In a previous study, we molecular-characterized a tomato (Solanum lycopersicum) alpha1, 3/4-fucosidase (alpha-Fuc'ase Sl-1) encoded in a tomato gene (Solyc03g006980), indicating that alpha-Fuc'ase Sl-1 is involved in the turnover of Lea epitope-containing N-glycans. In this study, we have characterized another tomato gene (Solyc11g069010) encoding alpha1, 3/4-fucosidase (alpha-Fuc'ase Sl 2), which is also active toward the complex type N-glycans containing Lea epitope(s). The baculovirus-insect cell expression system was used to express that alpha-Fuc'ase Sl-2 with anti-FLAG tag, and the expression product (rFuc'ase Sl-2), was found as a 65 kDa protein using SDS-PAGE and has an optimum pH of around 5.0. Similarly to rFuc'ase Sl-1, rFuc'ase Sl-2 hydrolyzed the non-reducing terminal alpha1, 3-fucose residue on LNFP III and alpha1, 4-fucose residues of Lea epitopes on plant complex type N-glycans, but not the core alpha1, 3-fucose residue on Manbeta1-4GlcNAcbeta1-4(Fucalpha1-3)GlcNAc or Fucalpha1-3GlcNAc. However, we found that both alpha-Fuc'ases Sl-1 and Sl-2 were specifically active toward alpha1, 3-fucose residue on GlcNAcbeta1-4(Fucalpha1-3)GlcNAc, indicating that the non-substituted beta-GlcNAc linked to the proximal GlcNAc residue of the core tri-saccharide moiety of plant specific N-glycans must be a pre-requisite for alpha-Fuc'ase activity. A 3 D modelled structure of the catalytic sites of alpha-Fuc'ase Sl-2 suggested that Asp192 and Glu236 may be important for binding to the alpha1, 3/4 fucose residue. PMID- 29444273 TI - Prevalence and determinants in cytology testing for cervical cancer screening in Spain (2006-14). AB - Background: Cervical cancer has decreased in developed countries thanks to cytology screening programmes. The aims of this study were To analyse the frequency and evolution of performing cytology tests and to determine the variables that influence their use. Methods: Cross-sectional study of non institutionalized women who participated in the national health survey (2006, 2011/12) and the European Health Survey in Spain (2009, 2014). Study variables: cytology-testing, time since last cytology-test, reason for performing the test, age, nationality, marital status, social status, education level and place of residence. Results: The study evaluated 53 628 women in Spain over 15 years old, with a mean age of 52.68 (SD +/- 19.12). About 94.1% were Spanish, 49.2% were married and 77.2% lived with a partner. In 2014, 72% had a cytology test, a number that increased significantly. Women aged 25-65 were 5.13 times more likely to undergo a cytology test than those aged 15-24 years old (odds ratio (OR): 5.13; P < 0.001); women with university educations were 9.23 times more likely to undergo a cytology test than those without university educations (P > 0.001); those of social classes I and II (high) were 1.2 more likely to undergo a cytology test than those of low social class (P = 0.026); and Spanish women were 1.74 times more likely to undergo a cytology test than foreigners living in Spain (P < 0.001). Conclusion: Frequency of cytology testing has increased in the last few years. Screening for cervical cancer is associated with higher social status, education level, age, and not being foreign. PMID- 29444274 TI - Shift work, parental cardiovascular disease and myocardial infarction in males. AB - Background: Shift work has been associated with an increased risk of cardiovascular disease (CVD). However, there is a need for more studies to determine whether there is an interaction between shift work and other risk factors of CVD, thereby increasing the risk of CVD in shift workers. Aims: To discern whether shift work and parental mortality from myocardial infarction (MI) or sudden cardiac death (SCD) interact to increase the risk of MI in men. Methods: A case-control dataset was used to assess interaction between shift work and parental history of CVD, using death from MI or SCD, or death before age 65, on an additive scale. Results were reported as relative excess risk due to interaction, attributable proportion due to interaction (AP) and synergy index (SI). Results: There was an interaction between shift work and paternal mortality from MI or SCD, when both factors were present [SI = 2.39; 95% confidence interval (CI) 1.02-5.6 and AP = 0.4; 95% CI 0.08-0.73]. Conclusions: Paternal mortality from MI or SCD interacts with shift work to increase the risk of MI in men. PMID- 29444275 TI - E-cigarette Advertising Exposure, Explicit and Implicit Harm Perceptions, and E Cigarette use Susceptibility Among Non-Smoking Young Adults. AB - Introduction: This study tested whether exposure to e-cigarette advertising increases e-cigarette use susceptibility among non-smoking young adults by promoting explicit and implicit attitudes towards e-cigarettes as a safer and healthier alternative to combustible cigarettes. Methods: Young adult current non smokers who had never used an e-cigarette (N = 393; Mean age = 22.1, Standard Deviation = 3.9; 66% Women) were randomly assigned to one of the 3 conditions that involved viewing real-world, print e-cigarette ads. Two of the 3 conditions were experimental conditions where ads with different predominant themes [harm reduction ("Health") vs. social enhancement ("Social") focused] were interspersed among ads of everyday objects. The third condition was the control condition involving ads of everyday objects only. Participants provided data on explicit (i.e., self-reported harm perceptions) and implicit (i.e., Implicit Association Test) attitudes towards e-cigarette use and e-cigarette use intentions. Hypotheses were tested using structural equation modeling. Results: Relative to Control participants, participants in Health and Social conditions were more likely to show higher implicit attitudes towards e-cigarettes as a safer alternative to cigarettes. Only the Social condition, relative to Control, had a significant effect on lower explicit harm perceptions of e-cigarette versus cigarette use. The Social condition had a significant indirect effect on e cigarette use susceptibility, mediated by explicit harm perceptions. Conclusions: Social enhancement-themed ads may communicate the reduced-harm messages more strongly among young adults so as to affect both explicit and implicit attitudes and, through these, e-cigarette use susceptibility. Regulatory bodies may need to scrutinize reduced-harm claims communicated through social enhancement-themed ads. PMID- 29444276 TI - Extracorporeal resuscitation as a further modifier of clinical outcome in patients with left ventricular assist device implantation and Interagency Registry for Mechanically Assisted Circulatory Support level 1. AB - In cardiogenic shock patients with Interagency Registry for Mechanical Circulatory Support (INTERMACS) level 1, the need for temporary circulatory support is a predictor and modifier of patient outcome. Because this group includes patients with and without cardiopulmonary resuscitation (CPR) and is thus very heterogeneous, we investigated whether a further subclassification is useful. We compared 30-day and 1-year mortality of patients who underwent left ventricular assist device implantation after extracorporeal CPR with the aid of an extracorporeal life support system (CPR+ group; n = 40) with cardiogenic shock patients in which the extracorporeal life support system was implanted under non CPR conditions (CPR- group, n = 68). In the CPR+ and CPR- groups, 30-day mortality was 27.5% (n = 11) and 8.8% (n = 6), respectively (P = 0.014). The values for 1-year mortality were 57.5% (n = 23) and 36.8% (n = 25), respectively (P = 0.023). The age- and gender-adjusted hazard ratios of 30-day and 1-year mortality for the CPR+ group and the CPR- group were 3.88 (95% confidence interval 1.29-11.7; P = 0.016) and 1.79 (95% confidence interval 1.01-3.17; P = 0.045), respectively. In conclusion, our data show that left ventricular assist device implantation with extracorporeal life support following CPR is associated with high 30-day and 1-year mortality. Further multicentre studies are needed to confirm these results and potentially add CPR as a new modifier to the INTERMACS profile. PMID- 29444277 TI - Pathophysiology and Management of Abdominal Myofascial Pain Syndrome (AMPS): A Three-Year Prospective Audit of a Management Pathway in 120 Patients. AB - Background: Chronic abdominal wall pain arising from the myofascial structures is termed abdominal myofascial pain syndrome and is an important cause of refractory abdominal pain that utilizes significant health care costs. The current literature is vague on its management. Design: The author presents a prospective audit of a structured management pathway and discusses the pathophysiology of abdominal myofascial pain syndrome. The objective was to identify an effective and durable treatment for the individual patient and evaluate patient satisfaction with the management pathway. Methods: Over a three-year period, 120 patients diagnosed with abdominal myofascial pain syndrome were included in a structured management pathway and were prospectively audited at a tertiary care university hospital. Results: Patient satisfaction with the pathway was high. Trigger point injection with local anesthetic was useful in diagnosis but ineffective in providing durable relief. Trigger point injection with steroids and pulsed radiofrequency treatment of trigger point(s) were effective therapeutic interventions, providing durable relief lasting six months in 32% and 60%, respectively. There was improvement reported in pain intensity scores, quality of life, anxiety, and depression scores following the interventional management of abdominal myofascial pain syndrome. Conclusions: Abdominal myofascial pain syndrome is often unrecognized, especially in patients with a history of visceral inflammation. The suggested pathway may be an option in its management. Trigger point injection with steroids may have a role in the differential diagnosis of chronic abdominal pain. PMID- 29444278 TI - Effectiveness of modified oral steroid administration for preventing esophageal stricture after entire circumferential endoscopic submucosal dissection. AB - Esophageal stricture occurs at a high rate after endoscopic submucosal dissection, especially after entire circumferential dissection, leading to poor quality of life. This retrospective cohort study evaluated the stricture rate in circumferential mucosal defect cases following modified steroid administration. We enrolled 22 consecutive patients who underwent entire circumferential endoscopic submucosal dissection for superficial esophageal cancer between April 2010 and April 2015 at our hospital. Until January 2013, a systemic steroid prednisolone-was administered at 30 mg/day and tapered over 8 weeks in the original method group (original group). From February 2013, 30 mg of prednisolone was administered orally for 3 weeks and then the dose was reduced in 5 mg decrements every 3 weeks. This group was classified as the modified method group (modified group). We retrospectively compared the stricture rates between the two groups. The postoperative stricture rate was significantly lower in the modified group (36.4%; 4/11 patients) than in the original group (82%; 9/11 patients; P = 0.04). The mean number of endoscopic balloon dilatation procedures was significantly lower in the modified group (6.2 +/- 11.3) than in the original group (19.4 +/- 15.3; P = 0.023). Pneumonia and oral herpes infection, which are adverse events potentially associated with steroid administration, were observed in the original group. Candida esophagitis, arthritis, and steroid-related myopathy were observed in the modified group. This modified systemic steroid administration was effective for patients with entire circumferential mucosal defect. The safety of this method was also demonstrated. PMID- 29444279 TI - Adult Brainstem Gliomas With H3K27M Mutation: Radiology, Pathology, and Prognosis. AB - Adult brainstem gliomas are difficult to classify based on radiologic and histologic features. A K27M mutation in histone 3 has been described to identify high-grade midline gliomas associated with a particularly unfavorable prognosis. While initially considered a pediatric entity, it is now known that H3K27M-mutant brainstem gliomas occur in all age groups, but they are less well understood in adults. We studied clinical, radiologic, and pathologic features of 25 brainstem gliomas diagnosed at our institution between 1994 and 2017 in subjects at least 18 years old. Seven tumors (28%) were positive for the H3K27M mutation, and their median overall survival was significantly shorter than in the H3-wildtype group (p = 0.004). Although the mutation was invariably associated with a poor prognosis, our study also illustrates the radiologic and pathologic heterogeneity in this molecular tumor subtype. The results showed that H3K27M-mutant status and clinically aggressive course cannot be ruled out based on low-grade histology on the initial biopsy, exophytic growth, only focal or minimal enhancement or an extrapontine location, such as midbrain or medulla. These results favor an integrated approach employing a combination of clinical, radiologic, histologic features as well as H3K27M immunohistochemistry for the diagnostic subclassification of adult brainstem gliomas. PMID- 29444280 TI - Prevalence of dementia in mainland China, Hong Kong and Taiwan: an updated systematic review and meta-analysis. AB - Background: There are several existing systematic reviews of prevalence of dementia for mainland China, Hong Kong and Taiwan, but several studies have been newly reported. The aim of this study is to update prevalence data in this region and test for variation across geographical areas and time periods using the new dataset. Methods: Twenty prevalence studies identified from World Alzheimer Report 2015 (January 2011-March 2015) and an updated search (March 2015-February 2017) were added to the original dataset (N = 76). Meta-regression was used to investigate geographical variation and time trends, taking methodological factors and characteristics of study population into account, and to estimate prevalence and number of people with dementia by geographical area. Results: Compared with northern China, the prevalence of dementia was lower in the central China [-1.0; 95% confidence interval (CI):-2.2, 0.3], south China (-1.7; 95% CI: -3.1, -0.3), Hong Kong and Taiwan (-3.0; 95% CI: -5.0, -1.0) but appeared to be higher in western China (2.8; 95% CI: 0.1, 5.5) after adjusting for methodological variation. The increasing trend from pre-1990 to post-2010 periods was considerably attenuated when taking into account methodological factors and geographical areas. The updated estimated number of people with dementia in all these areas is 9.5 million (5.3%; 95% CI: 4.3, 6.3) in the population aged 60 or above. Conclusions: Geographical variation in dementia prevalence is confirmed in this update, whereas evidence on increasing trends is still insufficient. Differing societal development across areas provides an opportunity to investigate risk factors at the population level operating across diverse life course experiences. Such research could advance global primary prevention of dementia.

PMID- 29444281 TI - Surgical management of esophageal sarcoma: a multicenter European experience. AB - Esophageal sarcomas are rare and evidence in literature is scarce making their management difficult. The objective is to report surgical and oncological outcomes of esophageal sarcoma in a large multicenter European cohort. This is a retrospective multicenter study including all patients who underwent en-bloc esophagectomy for esophageal sarcoma in seven European tertiary referral centers between 1987 and 2016. The main outcomes and measures are pathological results, early and long-term outcomes. Among 10,936 esophageal resections for cancer, 21 (0.2%) patients with esophageal sarcoma were identified. The majority of tumors was located in the middle (n = 7) and distal (n = 9) third of the esophagus. Neoadjuvant chemoradiotherapy was performed in five patients. All the patients underwent en-bloc transthoracic esophagectomy (19 open, 2 minimally invasive). Postoperative mortality occurred in 1 patient (5%). One patient received adjuvant chemotherapy. Definitive pathological results were carcinosarcoma (n = 7), leiomyosarcoma (n = 5), and other types of sarcoma (n = 9). Microscopic R1 resection was present in one patient (5%) and seven patients (33%) had positive lymph nodes. Median follow-up was 16 (3-79) months in 20 of 21 patients (95%). One-, 3-, and 5-year overall survival rates were 74%, 43%, and 35%, respectively. One-, 3- and 5-years disease-free survival rates were 58%, 40%, and 33%, respectively. Median overall survival was 6 months in N+ patients vs. 37 months for N0 patients (p = 0.06). At the end of the follow-up period, nine patients had died from cancer recurrences (43%), three patients died from other reasons (14%), one patient was still alive with recurrence (5%) and the seven remaining patients were free of disease (33%). Recurrence was local (n = 3), metastatic (n = 3), or both (n = 4). In conclusion, carcinosarcoma and leiomyosarcoma were the most common esophageal sarcoma histological subtypes. Lymph node involvement was seen in one third of cases. A transthoracic en-bloc esophagectomy with radical lymphadenectomy should be the best surgical option to achieve complete resection. Long-term survival remained poor with a high local and distant recurrence rate. PMID- 29444283 TI - Designing risk prediction models for ambulatory no-shows across different specialties and clinics. AB - Objective: As available data increases, so does the opportunity to develop risk scores on more refined patient populations. In this paper we assessed the ability to derive a risk score for a patient no-showing to a clinic visit. Methods: Using data from 2 264 235 outpatient appointments we assessed the performance of models built across 14 different specialties and 55 clinics. We used regularized logistic regression models to fit and assess models built on the health system, specialty, and clinic levels. We evaluated fits based on their discrimination and calibration. Results: Overall, the results suggest that a relatively robust risk score for patient no-shows could be derived with an average C-statistic of 0.83 across clinic level models and strong calibration. Moreover, the clinic specific models, even with lower training set sizes, often performed better than the more general models. Examination of the individual models showed that risk factors had different degrees of predictability across the different specialties. Implementation of optimal modeling strategies would lead to capturing an additional 4819 no-shows per-year. Conclusion: Overall, this work highlights both the opportunity for and the importance of leveraging the available electronic health record data to develop more refined risk models. PMID- 29444284 TI - Gentamicin-intercalated smectite as a new therapeutic option for Helicobacter pylori eradication. AB - Objectives: Novel antibacterial strategies against Helicobacter pylori are needed because H. pylori strains are acquiring resistance to antibiotics. We evaluated the efficacy of gentamicin-intercalated smectite hybrid (S-GEN)-based treatment regimens in a murine model of H. pylori infection. Methods: Two groups of 10 rats were administered either smectite or S-GEN to measure coverage of the gastric mucosa. To evaluate anti-H. pylori efficacy, mice were divided into eight groups of 10 mice each given different treatments, and H. pylori eradication was assessed by a Campylobacter-like organism (CLO) test and H. pylori PCR of the gastric mucosa, and H. pylori antigen and H. pylori PCR analysis of mouse faeces. The levels of proinflammatory cytokines were examined. Results: S-GEN was retained in the gastric mucosal layer with a >60% distribution ratio for up to 1 h, and the S-GEN-based triple regimen decreased bacterial burden in vivo compared with that of untreated mice or mice treated with other regimens. The cure rates in the CLO test and H. pylori PCR from gastric mucosa were 70%, 60%, 80%, 50%, 60% and 60% in Groups III-VIII, respectively. Those for H. pylori PCR in the faeces of mice were 90% and 100% in Group III with standard therapy and Group V with triple therapy including S-GEN, respectively. S-GEN triple therapy also reduced the levels of proinflammatory cytokines. Conclusions: These results suggest that S-GEN is a promising and effective therapeutic agent for the treatment of H. pylori infection.

PMID- 29444286 TI - Techniques to Ensure Accurate Targeting for Delivery of Awake Laser Interstitial Thermotherapy. AB - BACKGROUND: Magnetic resonance imaging (MRI) guided laser interstitial thermal therapy (LITT) is an emerging neurosurgical treatment modality that is typically performed under general anesthesia. We describe a novel workflow developed at the University of Florida to deliver LITT in conscious patients without the use of general anesthesia. OBJECTIVE: To describe a novel workflow for LITT implementation in the awake patient with equivalent treatment results when compared to procedures performed under general anesthesia. METHODS: For trajectories near a post of the Cosman-Roberts-Wells (CRW) frame (Integra LifeSciences, Plainsboro, New Jersey), we used preoperative MRI imaging to 3 dimensional-print a patient-specific mask with a trajectory guide to indicate the planned entry point during headframe placement. Otherwise, routine headframe placement and stereotactic registration were performed. Stereotactic biopsy and placement of the cranial bolt were performed in a standard neurosurgical operating room. The patient was transferred to a diagnostic MRI suite and positioned in the MRI scanner using beanbags and a custom molded thermoplastic mask. LITT was delivered with the patient conscious in the MRI scanner according to the manufacturer's recommendations. We collected patient demographics, treatment time, length of stay, and calculated preoperative tumor volume and postoperative ablation volumes. RESULTS: Ten sequential patients were treated with LITT from January 2016 until March 2017. The average preoperative tumor volume was 6.9 cm3. The average tissue volume ablated was 18.3 cm3. The mean operative time was 31 min (standard deviation [SD] 10 min) and mean time with laser delivery in MRI was 79 min (SD 27 min). The mean length of stay was 1.4 d (SD 0.9). There were no major complications. CONCLUSION: Using trajectory preplanning, customized face masks, and noninvasive head immobilization, LITT can be delivered to patients safely and accurately without general anesthesia. PMID- 29444287 TI - Mosquitoes of Northwestern Uganda. AB - Despite evidence of arbovirus activity in northwestern Uganda (West Nile Sub region), there is very limited information on the mosquito fauna of this region. The only published study reported 52 mosquito species in northwestern Uganda but this study took place in 1950 and the information has not been updated for more than 60 yr. In January and June 2011, CO2 baited-light traps were used to collect 49,231 mosquitoes from four different locations, Paraa (9,487), Chobe (20,025), Sunguru (759), and Rhino Camp (18,960). Overall, 72 mosquito species representing 11 genera were collected. The largest number of distinct species was collected at Chobe (43 species), followed by Paraa (40), Sunguru (34), and Rhino Camp (25). Only eight of the 72 species (11.1%) were collected from all four sites: Aedes (Stegomyia) aegypti formosus (Walker), Anopheles (Cellia) funestus group, Culex (Culex) decens group, Cx. (Culex) neavei Theobald, Cx. (Culex) univittatus Theobald, Cx. (Culiciomyia) cinereus Theobald, Cx. (Oculeomyia) poicilipes (Theobald), and Mansonia (Mansonoides) uniformis (Theobald). Fifty-four species were detected in northwestern Uganda for the first time; however, these species have been detected elsewhere in Uganda and do not represent new introductions to the country. Thirty-three species collected during this study have previously been implicated in the transmission of arboviruses of public health importance. PMID- 29444288 TI - LOB DOMAIN-CONTAINING PROTEIN 15 Positively Regulates Expression of VND7, a Master Regulator of Tracheary Elements. AB - Xylem includes xylem parenchyma cells, fibers and tracheary elements. Differentiation of tracheary elements is an irreversible process that is controlled by the master regulator VASCULAR-RELATED NAC-DOMAIN 7 (VND7). Molecular events occurring downstream of VND7 are well understood, but little is known regarding upstream regulation of VND7. In this study, we identified LOB DOMAIN-CONTAINING PROTEIN 15 (LBD15)/ASYMMETRIC LEAVES2-LIKE (ASL11) as a regulator of VND7. LBD15 was expressed in immature vascular cells and positively regulated both VND7 expression and differentiation of tracheary elements. LBD15 directly associated with the upstream sequence of VND7 and positively regulated VND7 expression. A 25 bp upstream sequence was essential for VND7 expression in the elongation zone of Arabidopsis roots. Taken together with previous studies identifying LBD15 as a target of VND7, we propose that LBD15 acts in a positive feedback regulation system that promotes and accelerates VND7 expression during the initiation phase of tracheary element differentiation in roots. PMID- 29444289 TI - Knowledge, attitude, and behaviors of health professionals towards smoking cessation in primary healthcare settings. AB - This study aimed to assess the behaviors of multiple health professionals in primary healthcare settings in Jordan towards smoking cessation counseling and to determine the barriers to effective smoking cessation behaviors. A survey of 456 health professionals in primary healthcare settings was conducted. A self administrated questionnaire was used to collect the data. About half of health professionals reported that they usually ask patients about smoking status and advise them to stop smoking (51.4% and 50.5%, respectively). Only 23.7% reported assessing the willingness of the patients to quit smoking and 17.9% reported discussing counseling options with smokers. Considerably fewer percentages of health professionals reported preparing their patients for withdrawal symptoms (6.0%), discussing pharmacotherapies (3.8%), and prescribing nicotine patches (6.4%). Key barriers to smoking cessation counseling, as reported by health professionals, included: insufficient resources and organizational support, limited coverage of cessation interventions, and lack of motivation to quit. Smoking cessation counseling was not routinely implemented by Jordanian health professionals. Barriers to effective delivery of smoking cessation counseling need to be integrated within relevant strategies aiming at enhancing the frequency and quality of health professionals' engagement in smoking cessation. PMID- 29444290 TI - Impact of renal allograft nephrectomy on graft and patient survival following retransplantation: a systematic review and meta-analysis. AB - Background: It is not clear whether renal allograft removal affects the outcome of renal retransplantation. This study aimed to determine the effect of allograft nephrectomy (AN) and no-AN (No AN) on renal retransplantation. Methods: A systematic review and meta-analysis were conducted using MEDLINE, Embase and the Cochrane Library. Observational studies or randomized controlled trials including renal retransplantation recipients with AN or No-AN were included. The primary outcomes were graft survival, patient survival, acute rejection (AR) and delayed graft dysfunction; the secondary outcomes were positive panel reactive antibody rate and serum creatinine level at 1 year after retransplantation, cold ischemia time and time of hemodialysis before recent transplantation. Pooled estimates of odds ratios (ORs) and the weighted mean difference for outcomes were calculated. Results: A total of 13 studies divided into 20 trials including 1923 patients were analyzed. The No-AN group had a significantly higher 3-year graft survival rate {OR 0.48 [95% confidence interval (CI) 0.34-0.69], 10 studies, n = 1030} and 5-year graft survival rate [OR 0.65 (95% CI 0.44-0.97), 16 studies, n = 1878] than the AN group. The rates of 5-year patient survival [OR 1.82 (95% CI 1.14 2.90), 5 studies, n = 749], positive panel reactive antibody [OR 3.08 (95% CI 2.08-4.56), 12 studies, n = 1225], AR [OR 1.59 (95% CI 1.21-2.09), 15 studies, n = 1388] and delayed graft dysfunction [OR 1.66 (95% CI 1.20-2.03), 8 studies, n = 879] were all significantly higher in the AN group. Compared with the No-AN group, cold ischemia time was longer in the AN group [weighted mean difference 1.84 (95% CI 0.90-2.79), 7 studies, n = 919]. The rate of 1-year graft survival and 10-year graft survival, serum creatinine levels at 1 year after retransplantation and the time of hemodialysis before recent transplantation were similar between the AN and No-AN groups. Conclusions: We recommend allowing the failed graft to remain unless symptoms dictate the need for surgery. We also suggest donor-specific antibody dynamic monitoring and better human leukocyte antigen matching for improved long-term outcome of retransplantation. PMID- 29444291 TI - Novel Sex Chromosomes in 3 Cichlid Fishes from Lake Tanganyika. AB - African cichlids are well known for their adaptive radiations, but it is now apparent that they also harbor an extraordinary diversity of sex chromosome systems. In this study, we sequenced pools of males and females from species in 3 different genera of cichlids from Lake Tanganyika. We then searched for regions that were differentiated following the patterns expected for sex chromosomes. We report 2 novel sex chromosomes systems, an XY system on LG19 in Tropheus sp. "black" and a ZW system on LG7 in Hemibates stenosoma. We also identify a ZW system on LG5 in Cyprichromis leptosoma that may be convergent with a system previously described in Lake Malawi cichlids. Our data also identify candidate single nucleotide polymorphisms for the blue/yellow tail color polymorphism observed among male C. leptosoma. PMID- 29444293 TI - The "Som la Pera" intervention: sustainability capacity evaluation of a peer-led social-marketing intervention to encourage healthy lifestyles among adolescents. AB - Sustainability capacity, always considered a challenge, is the ability to maintain effective long-term intervention in a community. The aim of the study was to improve the sustainability capacity of effective "Som la Pera," a school based, peer-led, social-marketing intervention that encourages healthy diet and physical activity, in low socioeconomic adolescents from Spain. The sustainability capacity was analyzed by a "programme sustainability assessment tool (PSAT)" comprising eight domains: political support, funding stability, partnerships, organizational capacity, programme evaluation, programme adaptation, communications, and strategic planning. Each domain was evaluated from 1 (no or to a small extent) to 7 points (to a great extent). The final score for sustainability capacity was the mean of the eight domain scores. The PSAT was assessed by nine professionals (researchers, staff members, and stakeholders) at two periods during intervention implementation: end of the first year (January 2015) and end of the second year (September 2015). At the end of the first year, strategic planning (4.43 +/- 1.98) and funding stability (4.38 +/- 1) were considered deficient domains, and at the end of the second year, these domains had improved by 1.67 points (p =.043) and 0.59 points (p = .159), respectively. The funding stability increase was not significant because only one of the five specific items, "policies implemented to ensure sustained funding," improved by 1.08 points (p = .036). The sustainability capacity final score was 5.93 +/- 1.13. The sustainability capacity assessment during the intervention allows its improvement before the programme expires, ensuring the long-term implementation of the "Som la Pera" intervention programme to encourage healthy lifestyles in adolescents. PMID- 29444294 TI - Prognosis of adult obstructive hypertrophic cardiomyopathy patients with different morphological types after surgical myectomy. AB - OBJECTIVES: This study aims to assess the impact of morphological type on the prognosis of obstructive hypertrophic cardiomyopathy patients who underwent myectomy. METHODS: We recruited 469 obstructive hypertrophic cardiomyopathy patients refractory to medicinal treatment who have undergone surgical myectomy at a nationwide referral centre. All patients were divided into 3 groups based on the morphological classification of left ventricular hypertrophy and were followed up by telephone every year. The primary end-points were sudden cardiac death, aborted sudden cardiac death and death due to heart failure or stroke. The secondary end-points were non-fatal cardiovascular events. RESULTS: Typical hypertrophy limited to the basal septum, hypertrophy of the whole ventricular septum and hypertrophy that involved the whole left ventricle were presented in 248 (52.9%), 141 (30.1%) and 80 (17.0%) patients, respectively. During the follow up of 2.5 +/- 1.4 years after myectomy, 10 (2.1%) and 43 (9.2%) patients met the primary end-point and secondary end-points, respectively. The maximal thickness of the ventricular septum, the left ventricular mass and the presence of extensive late gadolinium enhancement were lower in patients with hypertrophy limited to the basal septum than in other patients. Patients with the basal septum hypertrophy showed better survival after myectomy compared with other patients. For the secondary and composite end-points, there was no significant difference between the 3 groups. CONCLUSIONS: Patients with hypertrophy limited to the basal septum represented a special clinical subtype of obstructive hypertrophic cardiomyopathy showing better clinical outcomes, while diffuse hypertrophy of the ventricular septum and free wall indicated lower survival after surgical myectomy. PMID- 29444292 TI - Determinants of sleepiness in obstructive sleep apnea. AB - Study Objectives: Significant interindividual variability in sleepiness is observed in clinical populations with obstructive sleep apnea (OSA). This phenomenon is only partially explained by the apnea-hypopnea index (AHI). Understanding factors that lead to sleepiness is critical to effective management of patients with OSA. We examined demographic and other factors associated with sleepiness in OSA. Methods: Prospective study of 283 patients with newly diagnosed OSA by polysomnography (AHI >= 5 per hour). Subjective sleepiness (Epworth Sleep Scale [ESS] >= 11) and objective sleepiness (psychomotor vigilance task [PVT] mean lapse >= 2) were assessed. Results: Participants were classified into four groups (1: sleepy by ESS and PVT, 2: sleepy by PVT only, 3: sleepy by ESS only, and 4: nonsleepy reference group) and compared by generalized logit model. Shorter daily sleep duration by actigraphy and less morningness were associated with higher risk of sleepiness (Odds ratio [OR] = 0.52, 95% confidence interval [CI] 0.33-0.82 and OR = 0.89, CI 0.80-0.98, respectively). African American race was associated with sleepiness (group 1, OR = 8.8, CI 2.8-27.3; group 2, OR = 16.6, CI 3.3-83.6; and group 3, OR = 3.3, CI 1.0-10.1). IL-6 level was higher in groups 1 and 3 (OR = 1.9, CI 1.0-3.4 and OR 2.0, CI 1.1-3.7, respectively). Conclusions: African-American race, short sleep duration, chronotype, and increased proinflammatory cytokine IL-6 level were associated with sleepiness in OSA. These findings will inform future investigations determining mechanisms of sleepiness in OSA.

PMID- 29444296 TI - A Longitudinal Study of Depressive Symptoms, Neuropsychological Functioning, and Medical Responsibility in Youth With Spina Bifida: Examining Direct and Mediating Pathways. AB - Objective: Given the increased risk for cognitive deficits and development of depressive symptoms in youth with spina bifida (SB), this study aimed to examine two pathways through which depressive symptoms and neuropsychological dysfunction may be associated with medical autonomy in this population: (1) depressive symptoms as predictors of medical autonomy as mediated by attention/executive functioning (the cognitive scarring model), and (2) attention/executive functioning as predictors of medical autonomy as mediated by depressive symptoms (the cognitive vulnerability model). Methods: Participants were recruited as part of a larger, longitudinal study, and included 114 youth with SB (M age = 10.96 at Time 1), their parents, and teachers. Neuropsychological constructs included attention, working memory, and planning/organizing abilities, which were measured with questionnaire and performance-based data. Depressive symptoms and medical responsibility were assessed via questionnaires from multiple respondents. Results: Bootstrapped mediation analyses revealed that teacher-reported depressive symptoms significantly mediated the relations between neuropsychological functioning (i.e., attention and working memory) and medical responsibility (all p's < .05); neuropsychological dysfunction did not mediate the relationship between depressive symptoms and medical responsibility. Conclusions: One way in which neurocognitive dysfunction may hinder the development of medical autonomy in youth with SB is through an increased risk for depressive symptoms.

PMID- 29444297 TI - Draft genomes of two blister beetles Hycleus cichorii and Hycleus phaleratus. AB - Background: Commonly known as blister beetles or Spanish fly, there are more than 1500 species in the Meloidae family (Hexapoda: Coleoptera: Tenebrionoidea) that produce the potent defensive blistering agent cantharidin. Cantharidin and its derivatives have been used to treat cancers such as liver, stomach, lung, and esophageal cancers. Hycleus cichorii and Hycleus phaleratus are the most commercially important blister beetles in China due to their ability to biosynthesize this potent vesicant. However, there is a lack of genome reference, which has hindered development of studies on the biosynthesis of cantharidin and a better understanding of its biology and pharmacology. Results: We report 2 draft genomes and quantified gene sets for the blister beetles H. cichorii and H. phaleratus, 2 complex genomes with >72% repeats and approximately 1% heterozygosity, using Illumina sequencing data. An integrated assembly pipeline was performed for assembly, and most of the coding regions were obtained. Benchmarking universal single-copy orthologs (BUSCO) assessment showed that our assembly obtained more than 98% of the Endopterygota universal single-copy orthologs. Comparison analysis showed that the completeness of coding genes in our assembly was comparable to other beetle genomes such as Dendroctonus ponderosae and Agrilus planipennis. Gene annotation yielded 13 813 and 13 725 protein-coding genes in H. cichorii and H. phaleratus, of which approximately 89% were functionally annotated. BUSCO assessment showed that approximately 86% and 84% of the Endopterygota universal single-copy orthologs were annotated completely in these 2 gene sets, whose completeness is comparable to that of D. ponderosae and A. planipennis. Conclusions: Assembly of both blister beetle genomes provides a valuable resource for future biosynthesis of cantharidin and comparative genomic studies of blister beetles and other beetles. PMID- 29444299 TI - Early Nodal and Paranodal Disruption in Autoimmune Optic Neuritis. AB - Disturbances in the nodes of Ranvier are an early phenomenon in many CNS disorders, including the autoimmune demyelinating disease multiple sclerosis (MS). Using an animal model of optic neuritis, a common early symptom of MS, we have investigated nodal and paranodal compartments in the optic nerve during disease progression. Both nodes and paranodes, as identified by immunohistochemistry against sodium channels (Nav) and Caspr, respectively, were observed to increase in length during the late induction phase of the disease, prior to onset of the demyelination and immune cell infiltration characteristic of optic neuritis. These changes were correlated with both axonal stress and microglial/macrophage activation, and were most apparent in the vicinity of the retrobulbar optic nerve head, the unmyelinated region of the optic nerve where retinal ganglion cell axons exit the retina. Using intravitreal glutamate injection as a model of a primary retinal insult, we demonstrate that this can induce similar nodal and paranodal changes. This may suggest that onset of neurodegeneration in the absence of demyelination, as reported in several studies into the nonaffected eyes of MS patients, may give rise to subtle disturbances in the axo-glial junction. PMID- 29444300 TI - Deep Brain Stimulation for Parkinson Disease Does not Worsen or Improve Postural Instability: A Prospective Cohort Trial. AB - BACKGROUND: Falls and postural instability (PI) are major sources of morbidity in Parkinson disease (PD). Deep brain stimulation (DBS) is a major therapy for PD. The effects of DBS on PI and falls remain controversial. OBJECTIVE: To study if DBS worsens PI, validated measures of PI (Timed Up and Go, Berg Balance Scale, Unified Parkinson's Disease Rating Scale 3.12 [Pull Test], and the Biodex Sway Index with eyes closed on a firm and soft surface) and reported falls were used to prospectively evaluate the effect of DBS on PI at 3 and 12 mo postoperatively compared to baseline measurements. The primary outcomes were a positive result on 4 out of the 5 PI tests and falls. METHODS: Patients presenting for DBS were prospectively enrolled and evaluated at presentation and, 3 and 12 mo postoperatively. All tests were performed at each visit. RESULTS: At 3 mo 4 of 5 positive showed noninferiority to baseline, with a rate of 28% vs 41% (relative risk [RR] 0.8 [0.5-1.3]). At 12 mo, 4 of 5 positive had a rate of 35% vs 30% (RR 1.2 [0.8-1.8]) and falls had a rate of 54% vs 46% (RR 1.2 [0.6-2.3]). These did not meet criteria to prove noninferiority. Sensitivity analysis at 12 mo showed noninferiority for 4 of 5 (RR 0.9 [0.6-1.5]) but not falls (RR 1.1 [0.5-2.3]). CONCLUSION: This evidence is consistent with the hypothesis that DBS does not worsen PI when measured at 3 and 12 mo postoperatively. PMID- 29444301 TI - An integrative review exploring black men of African and Caribbean backgrounds, their fears of prostate cancer and their attitudes towards screening. AB - Evidence suggests that black men are disproportionately more affected than any other ethnicity by prostate cancer. The aim of this review is to identify studies exploring black men of African and Caribbean descent, their fears of prostate cancer and their attitudes towards screening. Four databases were searched and reference lists of relevant papers were hand searched. The inclusion criteria were studies exploring attitudes towards screening and fear of prostate cancer in black men of African and Caribbean backgrounds, peer-reviewed research, qualitative studies, surveys, questionnaires and English language publications. Qualitative findings were synthesized using a thematic framework to which quantitative findings were integrated. Of the 16 papers, 10 were quantitative and 6 were qualitative, all of which were conducted in the United States of America. Poorer and less educated black men were reluctant to seek help for prostate cancer. They may not visit their doctors for fear of intrusion into their personal lives. Moreover, they were fearful of being emasculated as a result of the digital rectal examination. The review identifies a paucity of UK literature on black men's fears and perceptions of prostate cancer. Further studies are needed in the United Kingdom to address this gap in the literature. PMID- 29444302 TI - RAB GTPases in the Basal Land Plant Marchantia polymorpha. AB - The RAB GTPase is an evolutionarily conserved machinery component of membrane trafficking, which is the fundamental system for cell viability and higher order biological functions. The composition of RAB GTPases in each organism is closely related to the complexity and organization of the membrane trafficking pathway, which has been developed uniquely to realize the organism-specific membrane trafficking system. Comparative genomics has suggested that terrestrialization and/or multicellularization were associated with the expansion of membrane trafficking pathways in green plants, which has yet to be validated in basal land plant lineages. To obtain insight into the diversification of membrane trafficking systems in green plants, we analyzed RAB GTPases encoded in the genome of the liverwort Marchantia polymorpha in a comprehensive manner. We isolated all genes for RAB GTPases in Marchantia and analyzed their expression patterns and subcellular localizations in thallus cells. While a majority of MpRAB GTPases exhibited a ubiquitous expression pattern, specific exceptions were also observed; MpRAB2b, which contains a sequence similar to an intraflagellar transport protein at the C-terminal region; and MpRAB23, which has been secondarily lost in angiosperms, were specifically expressed in the male reproductive organ. MpRAB21, which is another RAB GTPase whose homolog is absent in Arabidopsis, exhibited endosomal localization with RAB5 members in Marchantia. These results suggest that Marchantia possesses unique membrane trafficking pathways involving a unique repertoire of RAB GTPases. PMID- 29444303 TI - The Utility of Vancomycin Powder in Reducing Surgical Site Infections in Deep Brain Stimulation Surgery. AB - BACKGROUND: The impact of vancomycin powder on reducing postoperative surgical site infections (SSIs) in spine surgery has been studied extensively and is considered standard of care at many institutions. More recently, vancomycin powder has been shown to reduce SSI in cranial neurosurgery; however, limited studies have been performed assessing its impact in reducing SSIs in deep brain stimulation (DBS) surgery. OBJECTIVE: To investigate the use of vancomycin powder as an adjunct to the current antibiotic prophylaxis regimen in DBS surgery in a large cohort of patients. METHODS: All patients undergoing DBS-lead implantation surgery and chest generator placement or exchange were analyzed prior to and after the implementation of intrawound vancomycin powder, and the impact on infection rate and any complications were subsequently examined. RESULTS: From 2015 to 2017, a total of 419 consecutive patients (159 in the pretreatment group, 260 in the post-treatment group) were included in the study. The rate of SSI prior to implementation of intrawound vancomycin was 3.1% (n = 5), which was reduced to 0.38% (n = 1) in the post-treatment group. No complications were noted as a direct result of using vancomycin powder. CONCLUSION: Given its relatively low cost and side effect profile, the use of vancomycin powder may be an effective adjunct in reducing the rate of SSI in DBS surgery. PMID- 29444304 TI - Devolution and the regional health divide: a longitudinal ecological study of 14 countries in Europe. AB - Background: Greater regional devolution can reduce economic inequalities between regions; however, the impact on health inequalities is not clear. We investigated the association between changes over time in the level of devolution in European countries and regional economic and health inequalities. Methods: We used the proportion of government expenditure controlled by subnational levels of government as our measure of devolution in 14 European countries between 1995 and 2011. Fixed effects linear regression models were used to analyse trends in the level of devolution, trends in regional economic inequalities (Gini-coefficient) and trends in regional health inequalities (slope index) in life expectancy. Results: Each additional percentage of government expenditure managed at subnational level reduced the Gini-coefficient of regional GDP by -0.17 points (95% CI: -0.33 to -0.01; P = 0.04). However, it increased the slope index of regional life expectancy by 23 days (95% CI: -2 to 48; P = 0.07). When trends in regional economic inequalities were controlled for, as a potential mediator increased devolution-was significantly associated with an increase in health inequalities between regions (P = 0.01). Conclusions: Increased devolution does not appear to reduce regional health inequalities-even when it reduces regional economic inequalities-and it could be associated with increased health inequalities.

PMID- 29444306 TI - MpAMT1;2 from Marchantia polymorpha is a High-Affinity, Plasma Membrane Ammonium Transporter. AB - Plant ammonium transporters in the AMT/MEP/Rh (ammonium transporter/methylammonium and ammonium permease/Rhesus factor) superfamily have only been previously characterized in flowering plants (angiosperms). Plant AMT1s are electrogenic, while plant AMT2s are electroneutral, and MEP and Rh transporters in other organisms are electroneutral. We analyzed the transport function of MpAMT1;2 from the basal land plant Marchantia polymorpha, a liverwort. MpAMT1;2 was shown to localize to the plasma membrane in Marchantia gametophyte thallus by stable transformation using a C-terminal citrine fusion. MpAMT1;2 expression was studied using quantitative real-time PCR and shown to be higher when plants were N deficient and lower when plants were grown on media containing ammonium, nitrate or the amino acid glutamine. Expression in Xenopus oocytes and analysis by electrophysiology revealed that MpAMT1;2 is an electrogenic ammonium transporter with a very high affinity for ammonium (7 uM at pH 5.6 and a membrane potential of -137 mV). A conserved inhibitory phosphorylation site identified in angiosperm AMT1s is also present in all AMT1s in Marchantia. Here we show that a phosphomimetic mutation T475D in MpAMT1;2 completely inhibits ammonium transport activity. The results indicate that MpAMT1;2 may be important for ammonium uptake into cells in the Marchantia thallus. PMID- 29444307 TI - Senescence and nitrogen use efficiency in perennial grasses for forage and biofuel production. AB - Organ senescence is an important developmental process in plants that enables recycling of nutrients, such as nitrogen, to maximize reproductive success. Nitrogen is the mineral nutrient required in greatest amount by plants, although soil-N limits plant productivity in many natural and agricultural systems, especially systems that receive little or no fertilizer-N. Use of industrial N fertilizers in agriculture increased crop yields several fold over the past century, although at substantial cost to fossil energy reserves and the environment. Therefore, it is important to optimize nitrogen use efficiency (NUE) in agricultural systems. Organ senescence contributes to NUE in plants and manipulation of senescence in plant breeding programs is a promising approach to improve NUE in agriculture. Much of what we know about plant senescence comes from research on annual plants, which provide most of the food for humans. Relatively little work has been done on senescence in perennial plants, especially perennial grasses, which provide much of the forage for grazing animals and promise to supply much of the biomass required by the future biofuel industry. Here, we review briefly what is known about senescence from studies of annual plants, before presenting current knowledge about senescence in perennial grasses and its relationship to yield, quality, and NUE. While higher yield is a common target, desired N-content diverges between forage and biofuel crops. We discuss how senescence programs might be altered to produce high-yielding, stress tolerant perennial grasses with high-N (protein) for forage or low-N for biofuels in systems optimized for NUE. PMID- 29444308 TI - Integration of multi-omics techniques and physiological phenotyping within a holistic phenomics approach to study senescence in model and crop plants. AB - The study of senescence in plants is complicated by diverse levels of temporal and spatial dynamics as well as the impact of external biotic and abiotic factors and crop plant management. Whereas the molecular mechanisms involved in developmentally regulated leaf senescence are very well understood, in particular in the annual model plant species Arabidopsis, senescence of other organs such as the flower, fruit, and root is much less studied as well as senescence in perennials such as trees. This review addresses the need for the integration of multi-omics techniques and physiological phenotyping into holistic phenomics approaches to dissect the complex phenomenon of senescence. That became feasible through major advances in the establishment of various, complementary 'omics' technologies. Such an interdisciplinary approach will also need to consider knowledge from the animal field, in particular in relation to novel regulators such as small, non-coding RNAs, epigenetic control and telomere length. Such a characterization of phenotypes via the acquisition of high-dimensional datasets within a systems biology approach will allow us to systematically characterize the various programmes governing senescence beyond leaf senescence in Arabidopsis and to elucidate the underlying molecular processes. Such a multi-omics approach is expected to also spur the application of results from model plants to agriculture and their verification for sustainable and environmentally friendly improvement of crop plant stress resilience and productivity and contribute to improvements based on postharvest physiology for the food industry and the benefit of its customers.

AB - This study was conducted to assess the level of radioactivity and the radiation hazards associated with granite rocks used for construction of buildings. The measurement of radioactivity content of the rock samples was performed with gamma spectrometry equipped with Nal (TI) detector. From the results obtained in this study the average activity concentrations of 226Ra, 232Th and 40K were 20.64, 30.50 and 295.19 Bq kg-1, respectively. The absorbed dose rate in air at 1 m above ground level, the annual effective dose and the gamma index were determined with the aim to assess the possible radiological impact on inhabitants of dwellings built using such rocks. The mean value of the absorbed dose rate, the annual effective dose and the gamma index (Igamma) was 36.36 nGy h-1, 40.79 MUSv y-1 and 0.51 MUSv y-1, respectively. Radium equivalent activities, and external and internal hazard indices, were also calculated. These data indicated that the area of study lies within areas recognized as normal background radiation and the granite rocks are safe to be used as building material and other structural purposes.

AB - Background: The association between income inequality and health has been analyzed predominantly in developed countries with modest levels of inequality. The study aimed to analyze the association between income inequality and self reported health (SRH) in the adult population of the 27 Brazilian capitals. Methods: Individuals aged 18 years or older from the National Health survey residing in Brazilian capitals in 2013 were analyzed (n = 27 017). Bayesian multilevel models were applied after controlling for individual factors and area level socioeconomic characteristics. Results: We found a significant association between income inequality and SRH, even after controlling for individual and contextual factors. The results indicate greater odds of poor SRH among those living in areas with medium (OR = 1.31, 95% CI: 1.17-1.47) and high income inequality level (OR = 1.39, 95% CI: 1.24-1.56). Income inequality remained significantly associated with SRH, even after controlling for other contextual socioeconomic characteristics, such as local illiteracy rate, violence and per capita income. Conclusions: The study highlights the importance of the individual and contextual characteristics associated with SRH. Our findings suggest that city-level income inequality can have a detrimental effect on individual health, over and above other contextual socioeconomic characteristics and individual factors.

PMID- 29444312 TI - In Concert: Orchestrated Changes in Carbohydrate Homeostasis Are Critical for Plant Abiotic Stress Tolerance. AB - The sessile lifestyle of higher plants is accompanied by their remarkable ability to tolerate unfavorable environmental conditions. This is because, during evolution, plants developed a sophisticated repertoire of molecular and metabolic reactions to cope with changing biotic and abiotic challenges. In particular, the abiotic factors light intensity and ambient temperature are characterized by altering their amplitude within comparably short periods of time and are causative for onset of dynamic plant responses. These rapid responses in plants are also classified as 'acclimation reactions' which differ, due to their reversibility and duration, from non-reversible 'adaptation reactions'. In this review, we demonstrate the remarkable importance of stress-induced changes in carbohydrate homeostasis of plants exposed to high light or low temperatures. These changes represent a co-ordinated process comprising modifications of (i) the concentrations of selected sugars; (ii) starch turnover; (iii) intracellular sugar compartmentation; and (iv) corresponding gene expression patterns. The critical importance of these individual processes has been underlined in the recent past by the analyses of a large number of mutant plants. The outcome of these analyses raised our understanding of acclimation processes in plants per se but might even become instrumental to develop new concepts for directed breeding approaches with the aim to increase abiotic stress tolerance of crop species, which in most cases have high stress sensitivity. The latter direction of plant research is of special importance since abiotic stress stimuli strongly impact on crop productivity and are expected to become even more pronounced because of human activities which alter environmental conditions rapidly. PMID- 29444314 TI - Diffuse Astrocytoma, IDH-Wildtype: A Dissolving Diagnosis. AB - The histological and molecular features and even the mere existence of diffuse astrocytoma, IDH-wildtype, remain unclear. We therefore examined 212 diffuse astrocytomas (grade II WHO) in adults using IDH1(R132H) immunohistochemistry followed by IDH1/IDH2 sequencing and neuroimaging review. DNA methylation status and copy number profiles were assessed by Infinium HumanMethylation450k BeadChip. Only 25/212 patients harbored tumors without IDH1/IDH2 hotspot mutations and without contrast enhancement. By DNA methylation profiling, 10/25 tumors were classified as glioblastoma, IDH-wildtype, and an additional 7 cases could not be classified using methylome analysis, but showed genetic characteristics of glioblastoma. Histologically, all of these 17 tumors were low-grade diffuse astrocytomas. Nevertheless, 10/17 patients experienced early malignant progression. Other methylation classes included diffuse midline glioma, H3 K27M mutant, diffuse astrocytoma, IDH-mutant, pilocytic astrocytoma, and normal or reactive brain tissue (total n = 8). In conclusion, no convincing diffuse astrocytoma, IDH-wildtype, was identified. Most IDH-wildtype tumors showing histopathological and radiological features of low-grade diffuse astrocytoma exhibit molecular and clinical features of high-grade glioma and may represent an early stage of primary glioblastoma. Our findings have implications for the biology, classification and neuropathological diagnosis of diffuse astrocytoma, IDH-wildtype in adults.

AB - This study proposes a new dosimetry method for the estimation of the internal radiation dose distribution of a subject undergoing computed tomography (CT) examinations. In this novel method, dose distribution of a subject by CT scans was estimated based on radiophotoluminance distribution with polyethylene terephthalate (PET) resin which was cut to the average head size of a Japanese 1 year-old child. The difference in dose distribution depending on the type of bowtie filter was visualized by imaging luminance distribution with the PET phantom using a charge-coupled device camera. Dose distribution images simulated from a water phantom of the same size as the PET phantom were compared with the luminance distribution images. The linear correlation was demonstrated between luminance of the PET phantom and the simulated water dose. In comparison with the simulated water doses and the converted water doses from luminance of the PET phantom, the relative differences were within 20%. PMID- 29444317 TI - Melanization of a meristematic mutant of Fonsecaea monophora increase the pathogenesis in a BALB/c mice infection model. AB - The role of melanin in agents of chromoblastomycosis in vivo still remains unclear. In this study, we addressed the question in a BALB/c mice infection model by using an albino mutant, which generated from a melanized meristematic mutant of F. monophora. The most severe clinical manifestations of infected mice were observed at 10-25 dpi (day post infection) and 7-15 dpi for melanized and albino strain, respectively. Histopathologic examination were similar in both groups at 15 dpi (acute infection phase), but not at 30 dpi (sustained infection phase) and 45 dpi (recovery phase). Sclerotic body could be revealed in melanized strain infection group compare with albino strain infection group at 45 dpi. We found significantly elevated of TH2 cytokines in melanized strain infected group at 15 dpi, while increased expression level of TH1 and TH17 cytokines in albino strain infection group at 15 and 30 dpi. In conclusion, the present data addressed our speculation that melanization of this meristematic mutant of F. monophora could increase the pathogenesis in vivo. The inhibition of TH1 and TH17, exacerbated TH2 ability of melanized F. monophora is the key to escape the host immune system at the initial recognition and persistence in BALB/c mice.

PMID- 29444316 TI - Glucose triggers stomatal closure mediated by basal signaling through HXK1 and PYR/RCAR receptors in Arabidopsis. AB - Sugars play important roles in regulating plant growth, development, and stomatal movement. Here, we found that glucose triggered stomatal closure in a dose- and time-dependent manner in Arabidopsis. Pharmacological data showed that glucose induced stomatal closure was greatly inhibited by catalase [CAT; a reactive oxygen species (ROS) scavenger], diphenyleneiodonium chloride (DPI; an NADPH oxidase inhibitor), lanthanum chloride (LaCl3; a Ca2+ channel blocker), EGTA (a Ca2+ chelator), and two nitrate reductase (NR) inhibitors, tungstate and sodium azide (NaN3), while it was not affected by salicylhydroxamic acid (SHAM; a peroxidase inhibitor). Moreover, glucose induced ROS and nitric oxide (NO) production in guard cells of Arabidopsis. The ROS production was almost completely removed by CAT, strongly restricted by DPI, and was not affected by SHAM. NO production was partially suppressed by tungstate and NaN3, and the levels of NO were significantly reduced in the nia1-1nia2-5 mutant. Additionally, glucose-triggered stomatal closure was significantly impaired in gin1-1, gin2-1, pyr1pyl1pyl2pyl4, abi1-1, ost1, slac1-4, cpk6-1, and nia1-1nia2-5 mutants. Likewise, the reductions in leaf stomatal conductance (gs) and transpiration rate (E) caused by glucose were reversed in the above mutants. These results suggest that glucose-triggered stomatal closure may be dependent on basal signaling through PYR/RCAR receptors and hexokinase1 (HXK1). PMID- 29444319 TI - Beneficial effects of water-soluble chestnut (Castanea sativa Mill.) tannin extract on chicken small intestinal epithelial cell culture. AB - Feed and water supplementation with powdered hydrolyzable tannins from chestnut represents a valuable alternative strategy to antibiotics in animal nutrition. In this study, we evaluated the effects and safety of a water-soluble form of chestnut tannin (WST) in an in vitro model of chicken small intestinal epithelial cells (CSIEC). A chicken cell culture was established, and WST in concentrations of 0.025, 0.05, 0.1, and 0.2% were tested for cytotoxicity, cell proliferation, metabolic activity, production of reactive oxygen species, intracellular antioxidative potential, genotoxicity, and influence on the epithelia cell cycle. The tested concentrations showed a significant (P < 0.05) greater proliferative effect on CSIEC than the control medium (maximal proliferation at 0.1% WST as determined by optical density measurements). The 0.2% concentration of WST was cytotoxic, causing significantly higher (P < 0.05) nitric oxide and hydrogen peroxide production but with no short-term genotoxicity. Although increasing the concentration caused a decline in the metabolism of challenged cells (the lowest at 0.1% WST), metabolic activity remained higher than that in control cells. The antioxidant potential was 75% better and significantly (P < 0.05) higher in the 0.1% WST cultured cells compared to control. In conclusion, the cultured CSIEC are useful tools in basic and clinical research for the study of intestinal physiology, as they retain physiological and biochemical properties and epithelial morphology close to the original tissue and, in many ways, reflect the in vivo state. Our results indicate that WST exert a beneficial effect on intestinal epithelia, since they: i) stimulate proliferation of enterocytes; ii) increase antioxidative potential; iii) have no genotoxic effect; and iv) do not affect cellular metabolism. Our results reinforce the importance of WST as promising candidates for further evaluation and use in commercial broiler farm production. PMID- 29444320 TI - Effect of phytase on growth performance, phytate degradation and gene expression of myo-inositol transporters in the small intestine, liver and kidney of 21 day old broilers. AB - An experiment was conducted to evaluate phytase supplementation on growth, phytate degradation, and the gene expression of myo-inositol transporters in 21 day old broilers. Ross 308, male broilers (n = 240) were assigned to one of four diets, with 10 pens/diet and six birds/pen from day one to 21. The diets consisted of a negative control (NC) formulated to meet or exceed Ross 308 nutrient requirements, with the exception of calcium (Ca) and available P (avP), which were reduced by 0.16 and 0.15%, respectively. The NC diet was supplemented with 0, 500, 1,500, or 4,500 units/kg of phytase (FTU) to create four experimental diets. On day 21, all birds per pen were euthanized to obtain digesta and tissue samples for phytate degradation and gene expression. Data were analyzed as an analysis of variance using the fit model platform in JMP v 13.0. The model included phytase and significant means were separated using orthogonal linear and quadratic contrasts. Phytase supplementation increased gain (linear, P < 0.05). Phytate (iP6; quadratic, P < 0.05), phytate ester (iP5, iP4, iP3; quadratic, P < 0.05), and inositol (linear, P < 0.05) concentration in the gizzard was influenced by phytase supplementation. Phytate concentration decreased (linear, P < 0.05), iP5 or iP4 concentration increased and then decreased (quadratic, P < 0.05), and inositol concentration increased (quadratic, P < 0.05) in the ileal digesta as phytase supplementation increased in the diet. There was a tendency for the gene expression of the H+-dependent myo-inositol transporter, HMIT, to increase (linear, P < 0.05) in the ileum as phytase dose increased. Gene expression of the sodium-dependent myo-inositol transporter, SMIT2, increased in the jejunum (quadratic, P < 0.05) as phytase dose increased. Intestinal alkaline phosphatase expression increased (linear, P < 0.05) in the ileum as phytase supplementation increased in the diet. The influence of phytase on phytate, phytate esters, and inositol may influence intestinal alkaline phosphatase activity and the gene expression of myo-inositol transporters in the small intestine. PMID- 29444321 TI - Left ventricular regional dyssynchrony predicts improvements in moderate ischaemic mitral regurgitation after off-pump coronary artery bypass. AB - OBJECTIVES: The aim of this study was to explore the predictors of the improvement in moderate ischaemic mitral regurgitation (IMR) after off-pump coronary artery bypass grafting (OPCAB) focusing on left ventricular (LV) dyssynchrony. METHODS: A prospective study was performed among 135 patients (age at surgery, mean +/- SD: 67.0 +/- 8.2 years, 33.3% women) with prior myocardial infarction and moderate IMR undergoing OPCAB from 2008 to 2015. Preoperative and follow-up clinical and echocardiographic parameters were analysed, focusing on LV global/regional dyssynchrony. Patients were grouped by IMR at 1 year postoperatively: improved group with no or mild IMR (n = 61) and failure group with moderate or severe IMR (n = 67). Data were compared between groups to explore the predictors of IMR improvement after OPCAB. RESULTS: Seven patients who died before the 1-year postoperative assessment were excluded. At the 1-year follow up, there were 61 patients in the improved group and 67 patients in the failure group. Preoperatively, the improved group had smaller LV global dyssynchrony, LV regional dyssynchrony (papillary muscle systolic dyssynchrony; improved group versus failure group: 48.5 +/- 4.5 ms vs 57.1 +/- 3.9 ms; P < 0.001) and greater LV ejection fraction (improved group versus failure group: 44.7 +/- 5.0% vs 36.7 +/- 6.7%; P < 0.001) than the failure group. Papillary muscle systolic dyssynchrony (odds ratio 1.556, 95% confidence interval 1.313 1.845; P < 0.001) and preoperative ejection fraction (odds ratio 0.799, 95% confidence interval 0.691-0.924; P = 0.002) were independent predictors of moderate IMR improvement after OPCAB. CONCLUSIONS: In the selected patients, preoperative moderate IMR could be relieved by coronary artery bypass grafting. Greater ejection fraction and absence of LV regional dyssynchrony may predict the improvement in moderate IMR after coronary artery bypass grafting, suggesting that LV dyssynchrony especially regional dyssynchrony and preserved ventricular function would be important to the outcome of patients with moderate IMR. PMID- 29444322 TI - Physiological reactions to long-term fishing in the Barents Sea. AB - Background: Fishing in distant waters for months may induce physiological stress. Aims: To assess the physiological stress reactions in fishermen working for 2-3 months continuously in 6-h shifts on trawlers in the Barents Sea. Methods: The crew of five trawlers fishing in the Barents Sea from January to April 2004 were invited to participate. In the week before and 5-7 days after the trip, the following measures were collected: salivary cortisol four times a day, 24-h urinary cortisol, blood pressure, heart rate, serum cholesterol, serum high density lipoprotein (HDL-cholesterol), HbA1c (glycosylated haemoglobin) and weight. In addition, 24-h urinary cortisol, blood pressure and heart rate were measured three times. A questionnaire on health, social conditions and work environment was obtained after the trip. Results: In total, 136 men agreed to participate. Full data were obtained for 96 fishermen (70%). A significant decrease in salivary and urinary cortisol was found during the trip. Adjustment for age, body mass index, smoking, shift work schedule and time of day for sample collection did not change this finding. Systolic and diastolic blood pressure declined significantly and remained significantly lower after the trip compared to before the trip. Serum cholesterol/HDL ratio declined significantly, whereas triglycerides, HbA1c and weight were unchanged. Conclusions: Working up to 3 months on 6-h shifts, 84 h a week, with moderate physical activity, even in artificial light and cold weather on a ship, did not result in increased physiological stress. PMID- 29444323 TI - The role of fat and inflammation in the pathogenesis and management of osteoarthritis. AB - OA is a complex disease involving mechanical, metabolic and inflammatory contributions to its aetiology. A key risk factor, obesity, is becoming an increasing focus of research due to its multiple potential impacts on OA incidence, progression and symptom severity. An increased load due to an increase in body mass has been well established as a mechanical contribution to the pathophysiology of OA. However, evidence of obesity-linked to OA in non-weight bearing joints has implicated the biological role of adipose inflammation and metabolic abnormalities in OA. The identification of inflammatory mediators such as adipokines (adipose-derived molecules) in OA has further incriminated the role of adiposity. This narrative review aims to discuss the role of adipose-derived inflammation in OA, with a focus on the contrast between systemic and local adipose tissue, and potential treatment applications targeting the adipo inflammatory aspects of the disease.

PMID- 29444325 TI - Evaluation of the dissemination of SNaX, a middle school-based obesity prevention intervention, within a large US school district. AB - Few evidence-based school obesity-prevention programs are disseminated. We used community-based participatory research principles to disseminate an evidence based middle-school obesity-prevention program, Students for Nutrition and eXercise (SNaX), to a large, primarily Latino, school district. In the 2014-2015 school year, we trained a district "champion" to provide training and technical assistance to schools and supplied print- and web-based materials (www.snaxinschools.org). In one district region, 18 of 26 schools agreed to participate. We evaluated the dissemination process using the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework. All 18 schools implemented at least one SNaX component. Of 6,410 students who attended an informational session, 1,046 registered and 472 were selected to be Student Advocates, of whom 397 attended at least one meeting. Of 60 activities observed across schools, 77% were conducted with fidelity, but local resource constraints limited most activities to a relatively small number of Student Advocates (vs. the entire student body). Qualitative data from 46 school staff and 187 students indicated positive attitudes about the program. Teachers suggested that SNaX be implemented as part of the curriculum. In the 2015-2016 school year, 6 of the original schools continued to implement SNaX, and the champion trained 94 teachers from 57 schools districtwide. Cafeteria servings overall and fruit and vegetable servings, the primary outcomes, did not increase in SNaX schools versus matched-comparison schools. Our mixed-methods evaluation of SNaX showed acceptability and fidelity, but not effectiveness. Effectiveness may be improved by providing technical assistance to community stakeholders on how to tailor core intervention components while maintaining fidelity. PMID- 29444326 TI - Data maturity and follow-up in time-to-event analyses. AB - We propose methods to determine the minimum number of subjects remaining at risk after which Kaplan-Meier survival plots for time-to-event outcomes should be curtailed, as, once the number remaining at risk drops below this minimum, the survival estimates are no longer meaningful in the context of the investigation. The size of the decrease of the Kaplan-Meier survival estimate S(t) at time t if one extra event should occur is considered in two ways. In the first approach, the investigator sets a maximum acceptable absolute decrease in S(t) should one extra event occur. In the second, a minimum acceptable number of subjects still at risk is calculated by comparing the size of the decrease in S(t) if an extra event should occur with the variability of the survival estimate had all subjects been followed to that time (confidence interval approach). We recommend calculating both limits for the number still at risk and then making an informed choice in the context of the particular investigation. We explore further how the amount of information actually available can assist in considering issues of data maturity for studies whose outcome of interest is a survival percentage at a particular time point. We illustrate the approaches with a number of published studies having differing sample sizes and censoring issues. In particular, one study was the subject of some controversy regarding how far in time the Kaplan Meier plot should be extended. The proposed methods allow for limits to be calculated simply using the output provided by most statistical packages. PMID- 29444327 TI - Structural and Functional Analysis of UGT92G6 Suggests an Evolutionary Link Between Mono- and Disaccharide Glycoside-Forming Transferases. AB - Glycosylation mediated by UDP-dependent glycosyltransferase (UGT) is one of the most common reactions for the biosynthesis of small molecule glycosides. As glycosides have various biological roles, we characterized UGT genes from grapevine (Vitis vinifera). In silico analysis of VvUGT genes that were highly expressed in leaves identified UGT92G6 which showed sequence similarity to both monosaccharide and disaccharide glucoside-forming transferases. The recombinant UGT92G6 glucosylated phenolics, among them caffeic acid, carvacrol, eugenol and raspberry ketone, and also accepted geranyl glucoside and citronellyl glucoside. Thus, UGT92G6 formed mono- and diglucosides in vitro from distinct compounds. The enzyme specificity constant Vmax/Km ratios indicated that UGT92G6 exhibited the highest specificity towards caffeic acid, producing almost equal amounts of the 3 and 4-O-glucoside. Transient overexpression of UGT92G6 in Nicotiana benthamiana leaves confirmed the production of caffeoyl glucoside; however, the level of geranyl diglucoside was not elevated upon overexpression of UGT92G6, even after co-expression of genes encoding geraniol synthase and geraniol UGT to provide sufficient precursor. Comparative sequence and 3-D structure analysis identified a sequence motif characteristic for monoglucoside-forming UGTs in UGT92G6, suggesting an evolutionary link between mono- and disaccharide glycoside UGTs. Thus, UGT92G6 functions as a mono- and diglucosyltransferase in vitro, but acts as a caffeoyl glucoside UGT in N. benthamiana. PMID- 29444328 TI - Influence of Anatomic Changes on the Outcomes of Carotid Siphon Aneurysms After Deployment of Flow-Diverter Stents. AB - BACKGROUND: Flow-diverter stent (FDS) deployment can cause morphological and hemodynamic changes in the carotid siphon (CS), influencing the occlusion rate of aneurysms in this location. OBJECTIVE: To evaluate morphological changes to the CS after FDS deployment and their relationship with the rate of occlusion of intracranial aneurysms. METHODS: A cohort of 183 patients with CS aneurysms were treated by deployment of Pipeline(r) FDS (Medtronic Inc, Dublin, Ireland). Their CSs were classified as type U, V, C, or S, depending on morphology. The posterior and anterior bend angles were measured on strict lateral cerebral angiogram with digital subtraction before FDS deployment, immediately after deployment, and at 6 mo. Differences between angles were analyzed to identify any correlations with rates of aneurysm occlusion, using the O'Kelly-Marotta classification. RESULTS: FDS deployment was associated with immediate changes in CS morphology. The mean anterior angle increased from 3.97 +/- 25.06 degrees to 22.05 +/- 25.18 degrees (P < .001) and the mean posterior angle increased from 71.98 +/- 31.27 degrees to 79.43 +/- 31.80 degrees (P < .001). Multivariate analysis revealed a progressive, statistically significant increase in frequency of complete (grade D) occlusion at 6-mo follow-up with increasing anterior bend angle (prevalence ratios (PR) = 1.42 for increases between 5.3 degrees and 12 degrees , P = .017; PR = 1.56 for increases between 12.1 degrees and 27.6 degrees , P = .002; PR = 1.83 for increases >27.6 degrees , P < .001, all vs increases <5.3 degrees ). CONCLUSION: FDS deployment induces changes in CS morphology. Specifically, increases in mean anterior angle are associated with better radiological results on 6-mo follow-up digital subtraction angiography. PMID- 29444329 TI - Gastroesophageal reflux symptoms are not sufficient to guide esophageal function testing in lung transplant candidates. AB - Gastroesophageal reflux disease and esophageal dysmotility are prevalent in patients with advanced lung disease and are associated with graft dysfunction following lung transplantation. As a result, many transplant centers perform esophageal function testing as part of the wait-listing process but guidelines for testing in this population are lacking. The aim of this study is to describe whether symptoms of gastroesophageal reflux correlate with abnormal results on pH metry and high-resolution manometry and can be used to identify those who require testing. We performed a retrospective cohort study of 226 lung transplant candidates referred for high-resolution manometry and pH-metry over a 12-month period in 2015. Demographic data, results of a standard symptom questionnaire and details of esophageal function testing were obtained. Associations between the presence of symptoms and test results were analyzed using Fisher's exact tests and multivariable logistic regression. The most common lung disease diagnosis was interstitial lung disease (N = 131, 58%). Abnormal pH-metry was seen in 116 (51%) patients and the presence of symptoms was significantly associated with an abnormal study (p < 0.01). Dysmotility was found in 98 (43%) patients, with major peristaltic or esophageal outflow disorders in 45 (20%) patients. Symptoms were not correlated with findings on esophageal high-resolution manometry. Fifteen of 25 (60%) asymptomatic patients had an abnormal manometry or pH-metry. These results demonstrate that in patients with advanced lung disease, symptoms of gastroesophageal reflux increase the likelihood of elevated acid exposure on pH metry but were not associated with dysmotility. Given the proportion of asymptomatic patients with abnormal studies and associated post-transplant risks, a practice of universal high-resolution manometry and pH-metry testing in this population is justifiable. PMID- 29444330 TI - Increased species-assignment of filamentous fungi using MALDI-TOF MS coupled with a simplified sample processing and an in-house library. AB - In this study we evaluated the capacity of MALDI-TOF MS (Bruker Daltonics, Bremen, Germany) to identify clinical mould isolates. We focused on two aspects of MALDI-TOF MS identification: the sample processing and the database. Direct smearing of the sample was compared with a simplified processing consisting of mechanical lysis of the moulds followed by a protein extraction step. Both methods were applied to all isolates and the Filamentous Fungi Library 1.0 (Bruker Daltonics) was used for their identification. This approach allowed the correct species-level identification of 25/34 Fusarium spp. and 10/10 Mucor circinelloides isolates using the simplified sample processing. In addition, 7/34 Fusarium spp. and 1/21 Pseudallescheria/Scedosporium spp. isolates were correctly identified at the genus level. The remaining isolates-60-could not be identified using the commercial database, mainly because of the low number of references for some species and the absence of others. Thus, an in-house library was built with 63 local isolates previously characterized using DNA sequence analysis. Its implementation allowed the accurate identification at the species level of 94 isolates (91.3%) and the remaining nine isolates (8.7%) were correctly identified at the genus level. No misidentifications at genus level were detected. In conclusion, with improvements of both the sample preparation and the feeding of the database, MALDI-TOF MS is a reliable, ready to use method to identify moulds of clinical origin in an accurate, rapid, and cost-effective manner. PMID- 29444331 TI - Validation of the ACR-EULAR criteria for primary Sjogren's syndrome in a Dutch prospective diagnostic cohort. AB - Objectives: To validate the ACR-EULAR classification criteria for primary SS (pSS), and compare them to the American-European Consensus Group (AECG) and ACR criteria in a Dutch prospective diagnostic cohort. Methods: Consecutive patients (n = 129) referred for suspicion of pSS underwent a multidisciplinary evaluation, including a labial and/or parotid gland biopsy. Patients with an incomplete work up (n = 8) or associated systemic auto-immune disease (n = 7) were excluded. The ACR-EULAR classification was compared with expert classification, AECG and ACR classification. Additionally, the accuracy of individual ACR-EULAR items in discriminating pSS from non-pSS was evaluated. The validity of criteria sets was described separately using parotid or labial gland biopsy results for classification. Results: Of the 114 evaluated patients, the expert panel classified 34 (30%) as pSS and 80 (70%) as non-pSS. Using labial gland biopsy results, ACR-EULAR classification showed 87% absolute agreement (kappa = 0.73) with expert classification, with a sensitivity of 97% and specificity of 83%. Using the parotid gland biopsy results, the ACR-EULAR criteria performed excellently as well. Focus score, anti-SSA titre and ocular staining score showed good to excellent accuracy, whereas unstimulated whole saliva and Schirmer's test had poor accuracy. The ACR-EULAR and AECG criteria had equal validity. Compared with ACR classification, ACR-EULAR classification showed higher sensitivity but lower specificity. Conclusion: The ACR-EULAR criteria showed good agreement with expert classification, but some patients may be misclassified as pSS. Unstimulated whole saliva and Schirmer's test showed poor discriminative value. The ACR-EULAR criteria performed equally to the AECG criteria, and had higher sensitivity but lower specificity than the ACR criteria. PMID- 29444332 TI - Are Eating Disorders and Related Symptoms Risk Factors for Suicidal Thoughts and Behaviors? A Meta-analysis. AB - This meta-analysis addressed whether eating disorders (EDs) are risk factors (i.e., longitudinal predictors) for suicidal thoughts and behaviors. We identified 2,611 longitudinal studies published through August 1, 2017. Inclusion required studies include at least one longitudinal analysis predicting suicide ideation, attempt, or death using an ED diagnosis and/or symptom. Fourteen studies (42 prediction cases) met criteria. Results indicated that clinically diagnosed EDs and disordered eating symptoms were significant but weak predictors of suicide attempts but not death. Effects remained weak when moderators were considered. By reviewing the methodological limitations of previous research, these results highlight avenues for future research.

In the industrial oleaginous microalgae Nannochloropsis spp., the lack of an efficient methodology for chromatin immunoprecipitation (ChIP), which determines the specific genomic location of various histone modifications, has hindered probing the epigenetic basis of their photosynthetic carbon conversion and storage as oil. Here, a detailed ChIP protocol was developed for Nannochloropsis oceanica, which represents a reliable approach for the analysis of histone modifications, chromatin state, and transcription factor-binding sites at the epigenetic level. Using ChIP-qPCR, genes related to photosynthetic carbon fixation in this microalga were systematically assessed. Furthermore, a ChIP-Seq protocol was established and optimized, which generated a genome-wide profile of histone modification events, using histone mark H3K9Ac as an example. These results are the first step for appreciation of the chromatin landscape in industrial oleaginous microalgae and for epigenetics-based microalgal feedstock development.

AB - AIMS: The aim of this study was to evaluate the effectiveness of the mobile cooperation intervention in improving the competence and self-efficacy of students and the quality of the clinical learning environment. BACKGROUND: For students, the clinical practicum is challenging as such and moreover the student teacher cooperation, which supports the clinical learning of the students, has become complicated. Mobile applications have potential but their role in facilitating this cooperation remains unknown. DESIGN: A parallel-group randomized controlled trial. METHODS: Data were collected between January-March 2015 in Finland. The nursing students were randomly allocated to an intervention group (N = 52) or control group (N = 50). The intervention group used a mobile application to cooperate with the teacher during the clinical practicum. The control group engaged in standard cooperation. The primary outcome was competence. The secondary outcomes comprised self-efficacy and the quality of the clinical learning environment. Nurse Competence Scale, Self-efficacy in Clinical Performance instrument and the Clinical Learning Environment, Supervision and Nurse Teacher scale were used for student self-assessments. For the main analysis, hierarchical linear mixed models were used with the intention-to-treat principle. RESULTS: Competence and self-efficacy showed no significant between group differences in mean improvements, but significant improvements in both groups were detected over the 5 weeks. Satisfaction with the clinical learning environment showed no significant between-group differences, however, the role of the nurse teacher subscale, especially regarding cooperation, showed significant group differences. CONCLUSION: The mobile cooperation intervention was not significantly effective in improving individual outcomes, but did seem to improve significantly some aspects of the contextual outcomes.

AB - AIM: This paper introduces social network analysis as a versatile method with many applications in nursing research. BACKGROUND: Social networks have been studied for years in many social science fields. The methods continue to advance but remain unknown to most nursing scholars. DESIGN: Discussion paper. DATA SOURCES: English language and interpreted literature was searched from Ovid Healthstar, CINAHL, PubMed Central, Scopus and hard copy texts from 1965 - 2017. DISCUSSION: Social network analysis first emerged in nursing literature in 1995 and appears minimally through present day. To convey the versatility and applicability of social network analysis in nursing, hypothetical scenarios are presented. The scenarios are illustrative of three approaches to social network analysis and include key elements of social network research design. IMPLICATIONS FOR NURSING: The methods of social network analysis are underused in nursing research, primarily because they are unknown to most scholars. However, there is methodological flexibility and epistemological versatility capable of supporting quantitative and qualitative research. The analytic techniques of social network analysis can add new insight into many areas of nursing inquiry, especially those influenced by cultural norms. Furthermore, visualization techniques associated with social network analysis can be used to generate new hypotheses. CONCLUSION: Social network analysis can potentially uncover findings not accessible through methods commonly used in nursing research. Social networks can be analysed based on individual-level attributes, whole networks and subgroups within networks. Computations derived from social network analysis may stand alone to answer a research question or incorporated as variables into robust statistical models.

AB - AIM: The aim of this study was to psychometrically evaluate the Heart Failure Screening Tool (Heart-FaST) via: (1) examination of internal construct validity; (2) testing of scale function in accordance with design; and (3) recommendation for change/s, if items are not well adjusted, to improve psychometric credential. BACKGROUND: Self-care is vital to the management of heart failure. The Heart-FaST may provide a prospective assessment of risk, regarding the likelihood that patients with heart failure will engage in self-care. DESIGN: Psychometric validation of the Heart-FaST using Rasch analysis. METHOD: The Heart-FaST was administered to 135 patients (median age = 68, IQR = 59-78 years; 105 males) enrolled in a multidisciplinary heart failure management program. The Heart-FaST is a nurse-administered tool for screening patients with HF at risk of poor self care. A Rasch analysis of responses was conducted which tested data against Rasch model expectations, including whether items serve as unbiased, non-redundant indicators of risk and measure a single construct and that rating scales operate as intended. RESULTS: The results showed that data met Rasch model expectations after rescoring or deleting items due to poor discrimination, disordered thresholds, differential item functioning, or response dependence. There was no evidence of multidimensionality which supports the use of total scores from Heart FaST as indicators of risk. CONCLUSION: Aggregate scores from this modified screening tool rank heart failure patients according to their "risk of poor self care" demonstrating that the Heart-FaST items constitute a meaningful scale to identify heart failure patients at risk of poor engagement in heart failure self care. PMID- 29444339 TI - Nursing Intensive-Care Satisfaction Scale [NICSS]: Development and validation of a patient-centred instrument. AB - AIM: The aim of this study was to develop and validate the Nursing Intensive-Care Satisfaction Scale to measures satisfaction with nursing care from the critical care patient's perspective. BACKGROUND: Instruments that measure satisfaction with nursing cares have been designed and validated without taking the patient's perspective into consideration. Despite the benefits and advances in measuring satisfaction with nursing care, none instrument is specifically designed to assess satisfaction in intensive care units. DESIGN: Instrument development. METHODS: The population were all discharged patients (January 2013 - January 2015) from three Intensive Care Units of a third level hospital (N = 200). All assessment instruments were given to discharged patients and 48 hours later, to analyse the temporal stability, only the questionnaire was given again. The validation process of the scale included the analysis of internal consistency, temporal stability; validity of construct through a confirmatory factor analysis; and criterion validity. RESULTS: Reliability was 0.95. The intraclass correlation coefficient for the total scale was 0.83 indicating a good temporal stability. Construct validity showed an acceptable fit and factorial structure with four factors, in accordance with the theoretical model, being Consequences factor the best correlated with other factors. Criterion validity, presented a correlation between low and high (range: 0.42-0.68). CONCLUSIONS: The scale has been designed and validated incorporating the perspective of critical care patients. Thanks to its reliability and validity, this questionnaire can be used both in research and in clinical practice. The scale offers a possibility to assess and develop interventions to improve patient satisfaction with nursing care. PMID- 29444340 TI - Antipsychotics, Delirium, and Acute Respiratory Distress Syndrome: What Is the Link? AB - Acute respiratory distress syndrome (ARDS) is an acute inflammatory process that impairs the ability of the lungs to oxygenate and ultimately leads to respiratory failure. Patients who develop ARDS often have prolonged and complicated hospital courses putting them at risk for intensive care unit (ICU) delirium. Patients with ICU delirium often need chemical sedation, mechanical ventilation, prolonged duration of ICU and hospital stays, and they experience long-term cognitive impairment and increased mortality. In a patient with ARDS, ICU delirium further complicates the hospital course and increases the risk of morbidity and mortality. Antipsychotics are prescribed to decrease the severity and duration of ICU delirium, thus potentially decreasing their risk of morbidity and mortality. However, antipsychotics are associated with many adverse effects including respiratory failure. Given the long-term sequelae associated with the development of ICU delirium and the risks associated with antipsychotic use, clinicians must weigh the risks and benefits of antipsychotic use. This review investigates the interrelationship between ARDS, delirium, and antipsychotic use. In addition to discussing relevant studies evaluating antipsychotics for the prevention and treatment of delirium, we investigate safety concerns with the use of antipsychotics, especially as they relate to ARDS. Using the data compiled in this review, clinicians can make an informed decision about the use of antipsychotics for the prevention or treatment of delirium, with special consideration for their patients with ARDS. Future studies are needed to critically evaluate antipsychotic timing, dose, and duration for the prevention and treatment of ICU delirium and specifically evaluate the impact in special populations, particularly patients with ARDS. PMID- 29444341 TI - High-Fat Diet-Induced Obesity Promotes Expansion of Bone Marrow Adipose Tissue and Impairs Skeletal Stem Cell Functions in Mice. AB - Obesity represents a risk factor for development of insulin resistance and type 2 diabetes. In addition, it has been associated with increased adipocyte formation in the bone marrow (BM) along with increased risk for bone fragility fractures. However, little is known on the cellular mechanisms that link obesity, BM adiposity, and bone fragility. Thus, in an obesity intervention study in C57BL/6J mice fed with a high-fat diet (HFD) for 12 weeks, we investigated the molecular and cellular phenotype of bone marrow adipose tissue (BMAT), BM progenitor cells, and BM microenvironment in comparison to peripheral adipose tissue (AT). HFD decreased trabecular bone mass by 29%, cortical thickness by 5%, and increased BM adiposity by 184%. In contrast to peripheral AT, BMAT did not exhibit pro inflammatory phenotype. BM progenitor cells isolated from HFD mice exhibited decreased mRNA levels of inflammatory genes (Tnfalpha, IL1beta, Lcn2) and did not manifest an insulin resistant phenotype evidenced by normal levels of pAKT after insulin stimulation as well as normal levels of insulin signaling genes. In addition, BM progenitor cells manifested enhanced adipocyte differentiation in HFD condition. Thus, our data demonstrate that BMAT expansion in response to HFD exerts a deleterious effect on the skeleton. Continuous recruitment of progenitor cells to adipogenesis leads to progenitor cell exhaustion, decreased recruitment to osteoblastic cells, and decreased bone formation. In addition, the absence of insulin resistance and inflammation in the BM suggest that BMAT buffers extra energy in the form of triglycerides and thus plays a role in whole-body energy homeostasis.

PMID- 29444342 TI - The five-factor model of personality, work stress and professional quality of life in neonatal intensive care unit nurses. AB - AIMS: The study aim was to determine the direct and indirect relations of the five-factor model of personality traits and work stress with professional quality of life in neonatal nurses. BACKGROUND: Neonatal intensive care nursing has positive and negative effects on neonatal nurses' psychological well-being. Although individual and situational factors interact to influence professional quality of life, there have been few studies of these relationships in neonatal nurses. DESIGN: A cross-sectional study conducted in 2016. METHODS: Self-report questionnaires were used to measure professional quality of life (burnout, secondary traumatic stress and compassion satisfaction), five-factor model of personality traits (neuroticism, agreeableness, extraversion, conscientiousness and openness) and work stress (role ambiguity, role conflict and role overload). RESULTS: One hundred and forty (34%) of 405 eligible neonatal nurses provided the data. After controlling for work stress, neuroticism and agreeableness were related to burnout, neuroticism was related to secondary traumatic stress, and extraversion was related to compassion satisfaction. Work stress controlled for personality traits was related to burnout and secondary traumatic stress, but not to compassion satisfaction. Neuroticism moderated the effect of work stress on secondary traumatic stress and agreeableness and openness moderated the effect of work stress on compassion satisfaction. Work stress mediated the effect of neuroticism and extraversion on burnout and the effects of extraversion and conscientiousness on compassion satisfaction. CONCLUSION: Strategies to reduce work stress may not lessen burnout and secondary traumatic stress or increase compassion satisfaction in neonatal nurses who are prone to high neuroticism, low agreeableness and low extraversion.

AB - All Australian cases of methamphetamine-related suicide (2009-2015) retrieved from the National Coronial Information System were examined to determine crude mortality rates, characteristics and circumstances of death, and blood toxicology. There were 300 cases, 18.2% of all methamphetamine-related deaths, and 1.6% of all completed suicides. The mean age was 33.1 years, and 77.0% were male. The crude mortality rate was 1.9 per 106 , with males having a significantly higher rate than females (2.9 vs. 0.9 per 106 ). A quarter were known to have previous suicide attempts, and a history of psychosis was noted in 12.3%. In 40.7% of cases, witnesses described the decedent as having been agitated and/or aggressive immediately prior to the incident. The vast majority (85.3%), and of both sexes (males 87.0%, females 79.7%), used violent methods. Hanging (70.3%) was overwhelmingly the most frequent method among both males (70.1%) and females (71.0%). Prescription medications were frequently present: hypnosedatives (23.6%), antidepressants (19.5%), and antipsychotics (8.4%). Self poisoning cases were significantly more likely to have antidepressants (odds ratio: 4.2) and opioids (4.9) present, but less likely to have cannabis (0.3). Methamphetamine-related suicide makes a large contribution to methamphetamine related death and represents a substantial clinical and public health problem. PMID- 29444346 TI - Prenatal vitamin D status and respiratory and allergic outcomes in childhood: A meta-analysis of observational studies. AB - BACKGROUND: Prenatal vitamin D status may influence offspring's respiratory and allergic outcomes; however, evidence is inconclusive. A systematic review and meta-analysis were conducted on the association between 25-hydroxyvitamin D [25(OH)D] levels in maternal blood in pregnancy or cord blood at birth with the risk of offspring's respiratory and allergic conditions. METHODS: Two independent researchers conducted systematic searches for observational studies published until May 2017 using defined keywords on vitamin D and health outcomes, including respiratory tract infections (RTIs), wheeze, asthma, atopic eczema, allergic rhinitis, allergic sensitization, and lung function. Random-effects meta-analyses were conducted. RESULTS: A total of 34 from 547 retrieved articles were included. Increased prenatal exposure to 25(OH)D was inversely associated with risk of RTIs. Comparing the highest with the lowest category of 25(OH)D levels, the pooled odds ratio was 0.64 (95% CI 0.47, 0.87). A positive borderline association was found for lung function at school age (FEV1 z-score coefficient 0.07, 95% CI 0.01, 0.15). No associations were found for wheeze, asthma, atopic eczema, allergic rhinitis, and allergic sensitization. CONCLUSION: The introduction of public health measures to tackle vitamin D status in pregnancy may reduce the burden of RTIs in offspring. Current evidence does not support an impact on asthma and allergy. PMID- 29444347 TI - Inhibition of Escherichia coli O157:H7 on stainless steel using Pseudomonas veronii biofilms. AB - : We produced a Pseudomonas veronii biofilm on the surface of a stainless steel that is inhibitory to Escherichia coli O157:H7. Pseudomonas veronii strain KACC 81051BP, isolated from lettuce, readily formed biofilm on the surface of stainless steel coupons (SSCs) immersed in tryptic soy broth at 25 degrees C. Cells showed significantly (P <= 0.05) enhanced tolerance to desiccation stress (43% relative humidity (RH)) and retained antimicrobial activity against E. coli O157:H7. The number of E. coli O157:H7 (control; 4.1 +/- 0.1 log CFU per coupon) on sterile SSCs decreased to 2.7 +/- 0.2 log CFU per coupon after exposure to 43% RH at 25 degrees C for 48 h, while the population of E. coli O157:H7 (4.1 +/- 0.0 log CFU per coupon) on SSCs containing P. veronii biofilm decreased to below the theoretical detection limit (1.5 log CFU per coupon) within 24 h. The antimicrobial biofilm produced on stainless steel may have application in preventing cross-contamination by E. coli O157:H7 on other abiotic surfaces in food-contact environments. SIGNIFICANCE AND IMPACT OF THE STUDY: The presence of Escherichia coli O157:H7 on environmental surfaces of food manufacturing, transportation and storage facilities is a significant food safety concern because it can result in cross-contamination of food products. In this study, we developed a Pseudomonas veronii biofilm on the surface of a stainless steel that inhibits the growth of E. coli O157:H7. Since P. veronii in biofilm resists desiccation, it provides persistent antimicrobial activity. Information presented here provides novel and practical insights to developing biological strategies to inactivate E. coli O157:H7 on diverse surfaces in food processing and handling environments.

AB - Abacavir is a widely used nucleotide reverse transcriptase inhibitor, for which cerebrospinal fluid (CSF) exposure has been previously assessed in twice-daily recipients. We studied abacavir CSF concentrations in 61 and nine HIV-positive patients taking abacavir once daily and twice daily, respectively. Patients on once-daily abacavir had higher plasma and CSF concentrations (96 vs. 22 ng ml-1 , P = 0.038 and 123 vs. 49 ng ml-1 , P = 0.038) but similar CSF-to-plasma ratios (0.8 vs. 0.5, P = 0.500). CSF abacavir concentrations were adequate in patients receiving once-daily treatment. PMID- 29444349 TI - Suicidal Ideation in First-Episode Psychosis (FEP): Examination of Symptoms of Depression and Psychosis Among Individuals in an Early Phase of Treatment. AB - First-episode psychosis (FEP) is a particularly high-risk period for suicide, in which risk elevates by 60% within a first year of treatment as compared to later stages of illness. To date, much of the literature has focused on individuals with a longer duration of psychosis; thus, there is an urgency for research to examine suicide risk among individuals in FEP in the beginning stage of treatment. This study aimed to identify the relationships between demographic characteristics, symptoms of depression, psychosis (particularly positive symptoms of psychosis), and suicidal ideation among individuals in FEP. Secondary data were obtained from National Institute of Mental Health's Early Treatment Program of the Recovery After an Initial Schizophrenia Episode project (N = 404). Consistent with prior research, participants who experienced suicidal ideation during the study period reported having a longer duration of untreated psychosis and greater symptoms of depression. Further, positive symptoms of psychosis, namely hallucinations and delusions, were found to increase the odds of experiencing suicidal ideation. Findings point toward the implication that depression and positive symptoms of psychosis relate to the experience of suicidal ideation among individuals with a FEP and should be evaluated for and treated in the early stages of treatment. PMID- 29444350 TI - Nurses' beliefs about nursing diagnosis: A study with cluster analysis. AB - AIMS: To identify clusters of nurses in relation to their beliefs about nursing diagnosis among two populations (Italian and Spanish); to investigate differences among clusters of nurses in each population considering the nurses' socio demographic data, attitudes towards nursing diagnosis, intentions to make nursing diagnosis and actual behaviours in making nursing diagnosis. BACKGROUND: Nurses' beliefs concerning nursing diagnosis can influence its use in practice but this is still unclear. DESIGN: A cross-sectional design. METHODS: A convenience sample of nurses in Italy and Spain was enrolled. Data were collected between 2014-2015 using tools, that is, a socio-demographic questionnaire and behavioural, normative and control beliefs, attitudes, intentions and behaviours scales. RESULTS: The sample included 499 nurses (272 Italians & 227 Spanish). Of these, 66.5% of the Italian and 90.7% of the Spanish sample were female. The mean age was 36.5 and 45.2 years old in the Italian and Spanish sample respectively. Six clusters of nurses were identified in Spain and four in Italy. Three clusters were similar among the two populations. Similar significant associations between age, years of work, attitudes towards nursing diagnosis, intentions to make nursing diagnosis and behaviours in making nursing diagnosis and cluster membership in each population were identified. CONCLUSION: Belief profiles identified unique subsets of nurses that have distinct characteristics. Categorizing nurses by belief patterns may help administrators and educators to tailor interventions aimed at improving nursing diagnosis use in practice. PMID- 29444351 TI - Subyearling Siberian Sturgeon Acipenser baeri Fed a Diet Supplemented with ImmunoGen: Effects on Growth Performance, Body Composition, and Hematological and Serum Biochemical Parameters. AB - In this research, the effect of ImmunoGen (IMNO) on the growth indices, hematological parameters, and carcass composition of Siberian Sturgeon Acipenser baeri was investigated. After acclimation, fish (274.8 +/- 16.2 g) were allocated into 12 tanks (10 fish per tank) and triplicate groups were fed a control diet (0%) or diets containing 0.5, 1.0, or 1.5% IMNO for 75 d. At the end of the experiment, final length, final weight, and weight gain were significantly higher in the fish fed the diet containing 1.0% IMNO, though no significant differences were observed between the control and experimental diets containing 0.5% and 1.5% IMNO. In addition, there were no significant differences among diets in terms of hematological parameters and carcass composition. However, dietary IMNO significantly affected the serum biochemical parameters of Siberian Sturgeon, such as cholesterol, triglycerides, and IgM, with the highest level of IgM occurring in the 1.0% IMNO treatment and the lowest levels of cholesterol and triglycerides in the 1.5% IMNO treatment. The findings of this study thus indicate that the administration of 1.0% IMNO in diet positively affects the growth factors and some serum biochemical parameters of Siberian Sturgeon. PMID- 29444352 TI - Predictive performance of a genetic risk score using 11 susceptibility alleles for the incidence of Type 2 diabetes in a general Japanese population: a nested case-control study. AB - AIMS: To assess the predictive ability of a genetic risk score for the incidence of Type 2 diabetes in a general Japanese population. METHODS: This prospective case-control study, nested within a Japan Public Health Centre-based prospective study, included 466 participants with incident Type 2 diabetes over a 5-year period (cases) and 1361 control participants, as well as 1463 participants with existing diabetes and 1463 control participants. Eleven susceptibility single nucleotide polymorphisms, identified through genome-wide association studies and replicated in Japanese populations, were analysed. RESULTS: Most single nucleotide polymorphism loci showed directionally consistent associations with diabetes. From the combined samples, one single nucleotide polymorphism (rs2206734 at CDKAL1) reached a genome-wide significance level (odds ratio 1.28, 95% CI 1.18-1.40; P = 1.8 * 10-8 ). Three single nucleotide polymorphisms (rs2206734 in CDKAL1, rs2383208 in CDKN2A/B, and rs2237892 in KCNQ1) were nominally significantly associated with incident diabetes. Compared with the lowest quintile of the total number of risk alleles, the highest quintile had a higher odds of incident diabetes (odds ratio 2.34, 95% CI 1.59-3.46) after adjusting for conventional risk factors such as age, sex and BMI. The addition to the conventional risk factor-based model of a genetic risk score using the 11 single nucleotide polymorphisms significantly improved predictive performance; the c-statistic increased by 0.021, net reclassification improved by 6.2%, and integrated discrimination improved by 0.003. CONCLUSIONS: Our prospective findings suggest that the addition of a genetic risk score may provide modest but significant incremental predictive performance beyond that of the conventional risk factor-based model without biochemical markers. PMID- 29444354 TI - Clothing as a transport vector for airborne particles: Chamber study. AB - Strong evidence suggests that clothing serves as a reservoir of chemical pollutants and particles, including bioaerosols, which may have health significance. However, little is known about the role that clothing may play as a transport vector for inhaled airborne particles. Here, we contribute toward bridging the knowledge gap by conducting experiments to investigate clothing release fraction (CRF), determined as the size-dependent ratio of released to deposited particulate matter in the diameter range 0.5-10 MUm. In a fully controlled chamber with low background particle levels, we deployed a programmable robot to reproducibly quantify the size-dependent CRF as a function of motion type and intensity, dust loadings, and activity duration. On average, 0.3%-3% of deposited particles were subsequently released with fabric motion, confirming that clothing can act as a vehicle for transporting airborne particles. The CRF increased with the vigor of movement and with dust loading. Rubbing and shaking the fabric were more effective than fabric stretching in resuspending particles. We also found that most of the release happened quickly after the onset of the resuspension activity. Particle size substantially influenced the CRF, with larger particles exhibiting higher values. PMID- 29444353 TI - Healthcare resource utilisation associated with skeletal-related events in European patients with multiple myeloma: Results from a prospective, multinational, observational study. AB - OBJECTIVES: Patients with multiple myeloma (MM) often experience debilitating skeletal-related events (SREs: pathologic fracture, radiation to bone [RB], surgery to bone [SB] or spinal cord compression [SCC]). This is the first comprehensive, prospective, observational analysis of healthcare resource utilisation (HRU), independently attributed to SREs by investigators, in patients with MM. METHODS: Eligible patients had lytic bone lesions, life expectancy >=6 months, Eastern Cooperative Oncology Group performance status <=2 and >=1 SRE in the 97 days before enrolment. Data were collected retrospectively for 97 days before enrolment and prospectively for 18-21 months. RESULTS: Altogether, 153 patients were enrolled from Germany, Italy, Spain and the United Kingdom. Of the 281 observed SREs, 36.7% required inpatient stays (mean duration: 20.6 days per SRE [standard deviation (SD): 22.9]). SB and SCC were the SREs most likely to require stays (72.3% and 50.0% of SREs, respectively); SCC required the longest mean (SD) stay per event (40.5 [40.8] days). Overall, 179 SREs required outpatient visits; this was most likely for RB (74.8%) and least likely for non vertebral fracture (50.0%). CONCLUSIONS: All SREs were associated with substantial HRU; therefore, preventing SREs in MM will reduce the economic and resource burden on healthcare systems. PMID- 29444355 TI - Ethnic Variations of Trajectories in Suicide Ideation and Attempt: From Middle School to High School. AB - The purpose of this study was to compare patterns of suicide ideation and suicide attempt in three ethnic groups. We analyzed data from 463 students with ethnic backgrounds of African American (AA), Asian American (ASA), and European American (EA) for 6 years. The best fit model was a three-trajectory class model for all groups. The majority of adolescents belonged in the nonideators trajectory. The high level of ideation was found in the high ideators (4%), high-fluctuating ideators (8%), and high-decreasing ideators (4%) trajectory in AA, ASA, and EA, respectively. In the AA group, being a member of ideators was not a significant predictor of suicide attempt. In the ASA group, being a member of high fluctuating ideators was a significant predictor. In the EA group, being a member of both ideators predicted suicide attempt. The timing of onset, patterns of change, and peak time in the ideators trajectories in the three ethnic groups were markedly different. The high level of attempts found in the ASA-AA group was not explained by having suicide ideation. Findings suggest the need for in-depth examination of suicide behaviors across ethnic groups and culturally adapted preventive efforts with distinct developmental timing for adolescents from different ethnic backgrounds. PMID- 29444356 TI - Long-chain polyunsaturated fatty acids decline rapidly in milk from mothers delivering extremely preterm indicating the need for supplementation. AB - AIM: Our aim was to perform an in-depth analysis of the composition of fatty acids in milk from mothers delivering extremely preterm babies. We investigated longitudinal changes in milk fatty acid profiles and the relationship between several types of fatty acids, including omega-3 and omega-6. METHODS: Milk samples were collected at three stages of lactation from 78 mothers who delivered at less than 28 weeks of pregnancy at the Sahlgrenska University Hospital, Gothenburg, Sweden, from April 2013 to September 2015. Fatty acid composition was analysed by gas chromatography-mass spectrometry. RESULTS: A reduction in long chain polyunsaturated fatty acids (LCPUFAs) was observed during the lactation period. The concentrations of arachidonic acid and docosahexaenoic acid declined from medians of 0.34 to 0.22 mol% and 0.29 to 0.15 mol%, respectively, between postnatal day 7 and a postmenstrual age of 40 weeks. Strong correlations were found between the intermediates of several classes of fatty acids, including omega-3, omega-6 and omega-9. CONCLUSION: A rapid reduction in LCPUFA content in the mother's milk during the lactation period emphasises the importance of fatty acid supplementation to infants born extremely preterm, at least during the period corresponding to the third trimester, when rapid development of the brain and adipose tissue requires high levels of LCPUFAs. PMID- 29444357 TI - Safety of direct oral anticoagulants vs warfarin in patients with chronic liver disease and atrial fibrillation. AB - BACKGROUND: A complication of chronic liver disease (CLD) is the abnormality of coagulation. In clinical practice, this increased risk of bleeding has not been identified as a protective factor against stroke or systemic embolism associated with atrial fibrillation (AF). The objective of this study was to assess the safety of direct oral anticoagulant (DOAC) agents vs warfarin in CLD patients with AF. METHODS: This was a retrospective cohort study of patients with CLD and AF initiated on oral anticoagulants. Rates of all-cause bleeding were compared between warfarin and DOAC agents. Secondary endpoints included rates of major bleeding and other risk factors for bleeding on anticoagulant therapy. RESULTS: The all-cause bleeding rates were similar between the groups, with 8.4% per year in the DOAC (n = 75) group and 8.8% in warfarin (n = 158) group (HR 0.9, 95% CI 0.4-1.8). No significant difference was noted in the rate of major bleeding. In the multivariable model, higher MELD-XI score and previous bleed were risk factors associated with increased bleeding. CONCLUSION: No significant differences in bleeding rates were noted in patients treated with warfarin and DOAC agents. Further studies evaluating DOAC agents are needed to better understand the optimal anticoagulation strategy in setting of CLD. PMID- 29444358 TI - A Complex Role for Lipocalin 2 in Bone Metabolism: Global Ablation in Mice Induces Osteopenia Caused by an Altered Energy Metabolism. AB - Lipocalin 2 (Lcn2) is an adipokine that carries out a variety of functions in diverse organs. We investigated the bone phenotype and the energy metabolism of Lcn2 globally deleted mice (Lcn2-/- ) at different ages. Lcn2-/- mice were largely osteopenic, exhibiting lower trabecular bone volume, lesser trabecular number, and higher trabecular separation when compared to wild-type (WT) mice. Lcn2-/- mice showed a lower osteoblast number and surface over bone surface, and subsequently a significantly lower bone formation rate, while osteoclast variables were unremarkable. Surprisingly, we found no difference in alkaline phosphatase (ALP) activity or in nodule mineralization in Lcn2-/- calvaria osteoblast cultures, while less ALP-positive colonies were obtained from freshly isolated Lcn2-/- bone marrow stromal cells, suggesting a nonautonomous osteoblast response to Lcn2 ablation. Given that Lcn2-/- mice showed higher body weight and hyperphagia, we investigated whether their osteoblast impairment could be due to altered energy metabolism. Lcn2-/- mice showed lower fasted glycemia and hyperinsulinemia. Consistently, glucose tolerance was significantly higher in Lcn2-/- compared to WT mice, while insulin tolerance was similar. Lcn2-/- mice also exhibited polyuria, glycosuria, proteinuria, and renal cortex vacuolization, suggesting a kidney contribution to their phenotype. Interestingly, the expression of the glucose transporter protein type 1, that conveys glucose into the osteoblasts and is essential for osteogenesis, was significantly lower in the Lcn2-/- bone, possibly explaining the in vivo osteoblast impairment induced by the global Lcn2 ablation. Taken together, these results unveil an important role of Lcn2 in bone metabolism, highlighting a link with glucose metabolism that is more complex than expected from the current knowledge.

AB - INTRODUCTION: Cyclosporine and methotrexate are the two preferred first-line immunosuppressive treatments in atopic dermatitis. The aim of this study was to compare the treatment profiles of methotrexate and cyclosporine in daily practice as the first-line immunosuppressive treatment in atopic dermatitis, using two survival analyses, 'drug survival' (time on the drug) and 'postdrug survival' (time between two drugs). METHODS: Retrospective study including patients with moderate-to-severe atopic dermatitis treated with methotrexate or cyclosporine as the first-line immunosuppressive treatment. The reasons for discontinuation of treatment were collected as follows: controlled disease, treatment failure, side event pregnancy and non-compliance. 'Drug survival' and 'postdrug survival' analyses were performed using the Kaplan-Meier method and predictive factors were analysed using uni- and multivariate Cox regression analyses. RESULTS: Fifty-six patients, among whom 25 patients treated with cyclosporine and 31 with methotrexate (median age: 34 +/- 15 years), were included between 2007 and 2016. Reasons for discontinuation were not significantly different between 'controlled disease' and other reasons (P = 0.11). The median 'drug survival' was significantly longer for methotrexate (23 months) than for cyclosporine (8 months) (P < 0.0001). Six months from baseline, 93% of patients treated with methotrexate were still being treated vs 63% among patients treated with cyclosporine. The median of 'postdrug survival' was significantly longer for methotrexate (12 months) than for cyclosporine (2 months). Only treatment with CYC was a predictive factor for decreased 'drug survival' and 'postdrug survival'. CONCLUSION: This is the first direct comparison between methotrexate and cyclosporine as first-line immunosuppressive treatments for moderate-to severe atopic dermatitis in daily practice. We evidenced two different treatment profiles: the duration of methotrexate administration is longer than that of cyclosporine. 'Postdrug survival' could be a new tool to assess the maintenance of effect of a drug after withdrawal in atopic dermatitis, and more broadly in chronic skin disease.

PMID- 29444361 TI - Environmental exposure to polycyclic aromatic hydrocarbons, kitchen ventilation, fractional exhaled nitric oxide, and risk of diabetes among Chinese females. AB - Diabetes is related to exposure to polycyclic aromatic hydrocarbons (PAHs), inflammation in the body, and housing characters. However, associations of urinary monohydroxy-PAHs (OH-PAHs) or fractional exhaled nitric oxide (FeNO) with diabetes risk in relation to housing characters are unclear. In this study, 2645 individuals were drawn from the baseline survey of the Wuhan-Zhuhai Cohort Study. Associations of diabetes with urinary OH-PAHs or FeNO among cooking participants were estimated using logistic regression models. Among women with self-cooking meals, urinary OH-PAH levels were positively associated with diabetes risk (P < .05); the cooking women with high FeNO (>=25 ppb) had a 59% increase in the risk of diabetes (OR: 1.59, 95% CI: 1.06, 2.38), compared with those with low FeNO (<25 ppb). The cooking women with use of kitchen exhaust fans/hoods had a 52% decrease in the risk of diabetes (OR: 0.48, 95% CI: 0.27, 0.84), compared with those with nonuse of kitchen exhaust fans/hoods. The results indicated that the cooking women had an elevated risk of diabetes, which may be partly explained by an increase in the PAH body burden and higher inflammatory responses. Use of kitchen exhaust fan/hood can be associated with a lower risk of diabetes. PMID- 29444362 TI - The use of JAK inhibitors in the treatment of progressive systemic sclerosis.

A systematic review of observational studies. AB - Obesity has been associated with atopic dermatitis (AD); however, the results have been conflicting. Our aim was to provide an update on current knowledge from observational studies addressing the possible association between obesity and AD. Systematic literature review was performed by identifying studies addressing a possible link between AD and overweight/obesity from PubMed, EMBASE and the Cochrane Library in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. The quality of the included studies was assessed using the Newcastle-Ottawa Scale. A total of 45 studies (comprising more than 90 000 individuals with AD) fulfilled the criteria and were included in the present review. The available studies revealed inconsistencies, but the majority indicated that obesity is associated with AD. Studies addressing obesity in infancy or early childhood (age < 2 years) and AD reported a positive association. From childhood into adulthood, there is a discrepancy in the observations, as the more recent prospective studies found a positive association, whereas this was not observed in older cross-sectional studies. The inconsistency might be explained by the difference in study design, the diagnostic criteria of AD, regional differences, and by the varied definitions of overweight and obesity used in the studies. In Conclusion, overweight/obesity is associated with an increased risk of AD. Large prospective cohort studies are required to confirm the association between AD and obesity and the possibility that weight control in childhood may help to mitigate or reverse AD symptoms.

AB - Dynamic equilibrium between mitochondrial fission and mitochondrial fusion serves as an important quality control system within cells ensuring cellular vitality and homeostasis. Viruses often target mitochondrial dynamics as a part of their obligatory cellular reprogramming. The present study was undertaken to assess the status and regulation of mitochondrial dynamics during rotavirus infection. Distinct fragmentation of mitochondrial syncytia was observed during late hours of RV (SA11, Wa, A5-13) infection. RV nonstructural protein 4 (NSP4) was identified as the viral trigger for disrupted mitochondrial morphology. Severance of mitochondrial interconnections was found to be a dynamin-related protein 1 (Drp1)-dependent process resulting synergistically from augmented mitochondrial fission and attenuated mitochondrial fusion. Cyclin-dependent kinase 1 was subsequently identified as the cellular kinase responsible for fission-active Ser616 phosphorylation of Drp1. In addition to its positive role in mitochondrial fission, Drp1 also resulted in mitochondrial translocation of E3-ubiquitin ligase Parkin leading to degradation of mitochondrial fusion protein Mitofusin 1. Interestingly, RV-NSP4 was found to interact with and be involved in recruiting fission-active pool of Serine 616 phosphoDrp1 (Ser616 pDrp1) to mitochondria independent of accessory adaptors Mitochondrial fission factor and Fission protein 1 (Fis1). Inhibition of either Drp1 or Ser616 pDrp1 resulted in significant decrease in RV-NSP4-induced intrinsic apoptotic pathway. Overall, this study underscores an efficient strategy utilised by RV to couple apoptosis to mitochondrial fission facilitating dissemination of viral progeny. PMID- 29444368 TI - Establishment of an in vivo simulating co-culture assay platform for genotoxicity of multi-walled carbon nanotubes. AB - Engineered nanomaterials (ENM) are now used in a wide variety of fields, and, thus, their safety should urgently be assessed and secured. It has been suggested that inflammatory responses via the phagocytosis of ENM by macrophages is a key mechanism for their genotoxicity. The present study was conducted to establish a mechanism-based assay to evaluate the genotoxicity of ENM under conditions simulating an in vivo situation, featuring a co-culture system of murine lung resident cells (GDL1) and immune cells (RAW264.7). GDL1 were cultured with or without RAW264.7, exposed to a multi-walled carbon nanotube (MWCNT), and then analyzed for mutagenicity and underlying mechanisms. Mutation frequencies induced in GDL1 by the MWCNT were significantly greater with the co-existence of RAW264.7 than in its absence. Mutation spectra observed in GDL1 co-cultured with RAW264.7 were different from those seen in GDL1 cultured alone, but similar to those observed in the lungs of mice exposed to the MWCNT in vivo. Inflammatory cytokines, such as IL-1beta and TNF-alpha, were produced from RAW264.7 cells treated with the MWCNT. The generation of reactive oxygen species and the formation of 8-oxodeoxyguanosine in GDL1 exposed to the MWCNT were greater in the co-culture conditions than in the single culture conditions. Based on these findings, it is indicated that inflammatory responses are involved in the genotoxicity of MWCNT, and that the presently established, novel in vitro assay featuring a co-culture system of tissue resident cells with immune cells is suitable to evaluate the genotoxicity of ENM. PMID- 29444371 TI - Whole-exome sequencing for diagnosis of hereditary ichthyosis. AB - BACKGROUND: Hereditary ichthyosis constitutes a diverse group of cornification disorders. Identification of the molecular cause facilitates optimal patient care. OBJECTIVE: We wanted to estimate the diagnostic yield of applying whole exome sequencing (WES) in the routine genetic workup of inherited ichthyosis. METHODS: During a 3-year-period, all ichthyosis patients, except X-linked and mild vulgar ichthyosis, consecutively admitted to a university hospital clinic were offered WES with subsequent analysis of ichthyosis-related genes as a first line genetic investigation. Clinical and molecular data have been collected retrospectively. RESULTS: Genetic variants causative for the ichthyosis were identified in 27 of 34 investigated patients (79.4%). In all, 31 causative mutations across 13 genes were disclosed, including 12 novel variants. TGM1 was the most frequently mutated gene, accounting for 43.7% of patients suffering from autosomal recessive congenital ichthyosis (ARCI). CONCLUSION: Whole-exome sequencing appears an effective tool in disclosing the molecular cause of patients with hereditary ichthyosis seen in clinical practice and should be considered a first-tier genetic test in these patients. PMID- 29444370 TI - Cryptosporidium parvum disrupts intestinal epithelial barrier function via altering expression of key tight junction and adherens junction proteins. AB - Infection with the protozoan parasite Cryptosporidium parvum (CP) causes cryptosporidiosis, a widespread diarrhoeal disease. Impaired intestinal epithelial barrier function and increased permeability are most commonly associated with diarrhoeal diseases caused by enteric infections. However, studies on barrier disruption and underlying mechanisms in cryptosporidiosis are extremely limited. Epithelial tight junctions (TJs) and adherens junctions (AJs) are important in maintaining barrier integrity. Therefore, we examined the effects of CP infection on paracellular permeability and on the expression of the major TJ and AJ proteins utilising in vitro, ex vivo, and in vivo models. CP infection (0.5 * 106 oocysts/well in Transwell inserts, 24 hr) increased paracellular permeability (FITC-dextran flux) in Caco-2 cell monolayers and substantially decreased the protein levels of occludin, claudin 4, and E cadherin. Claudin 3, zonula occludens-1 (ZO1) and alpha-catenin were also significantly decreased, whereas claudins 1 and 2 and beta-catenin were not altered. Substantial downregulation of occludin, claudin 4, and E-cadherin was also observed in response to CP infection ex vivo in mouse enteroid-derived monolayers and in vivo in the ileal and jejunal mocosa of C57BL/6 mice. The mRNA levels of these proteins were also significantly decreased in CP-infected mouse ileum and jejunum but were unaltered in Caco-2 cells. Further, bafilomycin-A, an inhibitor of lysosomal proton pump, partially abrogated CP effects on occludin expression in Caco-2 cells, suggesting a potential role of posttranslational mechanisms, such as induction of protein degradation pathways, in mediating the effects of the parasite. Our studies suggest that disruption of barrier function via downregulation of specific key components of TJ and AJ could be a major mechanism underlying CP infection-induced diarrhoea.

PMID- 29444373 TI - Changes in apoplastic peroxidase activity and cell wall composition are associated with cold-induced morpho-anatomical plasticity of wheat leaves. AB - Temperate grasses, such as wheat, become compact plants with small thick leaves after exposure to low temperature. These responses are associated with cold hardiness, but their underlying mechanisms remain largely unknown. Here we analyse the effects of low temperature on leaf morpho-anatomical structure, cell wall composition and activity of extracellular peroxidases, which play key roles in cell elongation and cell wall thickening, in two wheat cultivars with contrasting cold-hardening ability. A combined microscopy and biochemical approach was applied to study actively growing leaves of winter (ProINTA-Pincen) and spring (Buck-Patacon) wheat developed under constant warm (25 degrees C) or cool (5 degrees C) temperature. Cold-grown plants had shorter leaves but longer inter-stomatal epidermal cells than warm-grown plants. They had thicker walls in metaxylem vessels and mestome sheath cells, paralleled with accumulation of wall components, predominantly hemicellulose. These effects were more pronounced in the winter cultivar (Pincen). Cold also induced a sharp decrease in apoplastic peroxidase activity within the leaf elongating zone of Pincen, and a three-fold increase in the distal mature zone of the leaf. This was consistent with the enhanced cell length and thicker cell walls in this cultivar at 5 degrees C. The different response to low temperature of apoplastic peroxidase activity and hemicellulose between leaf zones and cultivar types suggests they might play a central role in the development of cold-induced compact morphology and cold hardening. New insights are presented on the potential temperature-driven role of peroxidases and hemicellulose in cell wall dynamics of grasses.

PMID- 29444375 TI - The efficacy and safety of non-pharmacological therapies for the treatment of acne vulgaris: A systematic review and best-evidence synthesis. AB - BACKGROUND: Acne vulgaris is a multifaceted skin disorder, affecting more than 85% of young individuals worldwide. Pharmacological therapy is not always desirable because of the development of antibiotic resistance or the potential risk of adverse effects. Non-pharmacological therapies can be viable alternatives for conventional therapies. However, sufficient evidence-based support in the efficacy and safety of non-pharmacological therapies is lacking. OBJECTIVE: To assess the efficacy and safety of several non-pharmacological therapies in the treatment of acne vulgaris. METHODS: A systematic literature review, including a best-evidence synthesis, was performed to identify literature. Three electronic databases were accessed and searched for studies published between January 2000 and May 2017. RESULTS: Thirty-three eligible studies were included in our systematic review. Three main types of non-pharmacological therapies were identified laser- and light-based therapies, chemical peels and fractional microneedling radiofrequency. The majority of the included studies demonstrated a significant reduction in acne lesions. However, only seven studies had a high methodologic quality. Based on these seven trials, a best-evidence synthesis was conducted. Strong evidence was found for glycolic acid (10-40%). Moderate evidence was found for amino fruit acid (20-60%), intense pulsed light (400-700 and 870-1200 nm) and the diode laser (1450 nm). Initially, conflicting evidence was found for pulsed dye laser (585-595 nm). The most frequently reported side effects for non-pharmacological therapies included erythema, tolerable pain, purpura, oedema and a few cases of hyperpigmentation, which were in most cases mild and transient. CONCLUSION: Circumstantial evidence was found for non pharmacological therapies in the treatment of acne vulgaris. However, the lack of high methodological quality among included studies prevented us to draw clear conclusions, regarding a stepwise approach. Nevertheless, our systematic review including a best-evidence synthesis did create order and structure in resulting outcomes in which a first step towards future research is generated. PMID- 29444376 TI - Secukinumab demonstrates high sustained efficacy and a favourable safety profile in patients with moderate-to-severe psoriasis through 5 years of treatment (SCULPTURE Extension Study). AB - BACKGROUND: Secukinumab, a fully human monoclonal antibody that selectively neutralizes IL-17A, has been shown to have significant efficacy and a favourable safety profile in the treatment of moderate-to-severe psoriasis and psoriatic arthritis. OBJECTIVE: To assess the efficacy and safety of secukinumab through 5 years of treatment in moderate-to-severe psoriasis. METHODS: In the core SCULPTURE study, Psoriasis Area and Severity Index (PASI) 75 responders at Week 12 continued receiving subcutaneous secukinumab until Year 1. Thereafter, patients entered the extension phase and continued treatment as per the core trial. Treatment was double-blinded until the end of Year 3 and open-label from Year 4. Here, we focus on the 300 mg fixed-interval (every 4 weeks) treatment, the recommended per label dose. Efficacy data are primarily reported as observed, but multiple imputation (MI) and last observation carried forward (LOCF) techniques were also undertaken as supportive analyses. RESULTS: At Year 1, 168 patients entered the extension study and at the end of Year 5, 126 patients completed 300 mg (every 4 weeks) treatment. PASI 75/90/100 responses at Year 1 (88.9%, 68.5% and 43.8%, respectively) were sustained to Year 5 (88.5%, 66.4% and 41%). PASI responses were consistent regardless of the analysis undertaken (as observed, MI, or LOCF). The average improvement in mean PASI was approximately 90% through 5 years compared with core study baseline. DLQI (dermatology life quality index) 0/1 response also sustained through 5 years (72.7% at Year 1 and 65.5% at Year 5). The safety profile of secukinumab remained favourable, with no cumulative or unexpected safety concerns identified. CONCLUSION: Secukinumab 300 mg treatment delivered high and sustained levels of skin clearance and improved quality of life through 5 years in patients with moderate-to-severe psoriasis. Favourable safety established in the secukinumab phase 2/3 programme was maintained through 5 years. PMID- 29444377 TI - A biomechanical analysis of prognathous and orthognathous insect head capsules: evidence for a many-to-one mapping of form to function. AB - Insect head shapes are remarkably variable, but the influences of these changes on biomechanical performance are unclear. Among 'basal' winged insects, such as dragonflies, mayflies, earwigs and stoneflies, some of the most prominent anatomical changes are the general mouthpart orientation, eye size and the connection of the endoskeleton to the head. Here, we assess these variations as well as differing ridge and sclerite configurations using modern engineering methods including multibody dynamics modelling and finite element analysis in order to quantify and compare the influence of anatomical changes on strain in particular head regions and the whole head. We show that a range of peculiar structures such as the genal/subgenal, epistomal and circumocular areas are consistently highly loaded in all species, despite drastically differing morphologies in species with forward-projecting (prognathous) and downward projecting (orthognathous) mouthparts. Sensitivity analyses show that the presence of eyes has a negligible influence on head capsule strain if a circumocular ridge is present. In contrast, the connection of the dorsal endoskeletal arms to the head capsule especially affects overall head loading in species with downward-projecting mouthparts. Analysis of the relative strains between species for each head region reveals that concerted changes in head substructures such as the subgenal area, the endoskeleton and the epistomal area lead to a consistent relative loading for the whole head capsule and vulnerable structures such as the eyes. It appears that biting-chewing loads are managed by a system of strengthening ridges on the head capsule irrespective of the general mouthpart and head orientation. Concerted changes in ridge and endoskeleton configuration might allow for more radical anatomical changes such as the general mouthpart orientation, which could be an explanation for the variability of this trait among insects. In an evolutionary context, many-to-one mapping of strain patterns onto a relatively similar overall head loading indeed could have fostered the dynamic diversification processes seen in insects. PMID- 29444378 TI - Examining relationships between total silver concentration and Sil silver resistance genes in domestic wastewater treatment plants. AB - AIMS: The overarching aims of this study were to determine if microbes found in wastewater treatment plants (WWTPs) carry silver resistance genes and ascertain whether a relationship exists between silver loading and sil silver resistance gene copy numbers. METHODS AND RESULTS: Activated sludge samples were collected from 17 WWTPs across the United States and characterized for chemical oxygen demand (COD) and total silver concentration. Gene copy numbers were quantified using qPCR for four common silver resistance genes (silC, silP, silR and silS). Spearman correlation analyses were performed to examine associations between three WWTP characteristics (i.e. size, COD and total silver concentration) and sil gene copy numbers. sil genes were found in all activated sludge samples, however the quantity of gene copy numbers was inconsistent. Of the sil genes screened, silS was the most abundant, followed by silR. Gene copy numbers for silC and silP were generally similar and overall lower than silS and silR. CONCLUSIONS: Neither individual or combined sil gene copy numbers correlated significantly with total silver concentration, suggesting either the presence of alternate mechanisms of silver resistance or that a critical silver concentration threshold within WWTPs was not met that would require specific resistance against silver. SIGNIFICANCE AND IMPACT OF THIS STUDY: To the authors' knowledge, this is one of the first studies to measure the prevalence of sil genes in engineered systems. Results from this study suggest that at least four silver resistance genes are commonly found within WWTP-activated sludge, however it is unclear if these genes are being expressed under current total silver loadings.

MSSA-10 triggered oxidative stress responsive mechanisms and regulated the growth of pea plants under induced saline environment. AB - AIMS: The study was planned to characterize Planomicrobium sp. MSSA-10 for plant beneficial traits and to evaluate its inoculation impact on physiology of pea plants under different salinity levels. METHODS AND RESULTS: Strain MSSA-10 was isolated from pea rhizosphere and identified by the analysis of 16S rRNA gene sequence. The strain demonstrated phosphate solubilization and auxin production up to 2 mol l-1 NaCl and exhibited 1-aminocyclopropane-1-carboxylic acid deaminase activity up to 1.5 mol l-1 salt. In an inoculation experiment under different salinity regimes, a significant increase in growth was observed associated with decreased levels of reactive oxygen species and enhanced antioxidative enzyme activities. The strain also promoted the translocation of nutrients in plants with subsequent increase in chlorophyll and protein contents as compared to noninoculated plants. It has been observed that rifampicin resistant derivatives of MSSA-10 were able to survive for 30 days at optimum cell density with pea rhizosphere. CONCLUSION: Growth-stimulating effect of MSSA-10 on pea plants may be attributed to its rhizosphere competence, nutrient mobilization and modulation of plant oxidative damage repair mechanisms under saline environment. SIGNIFICANCE AND IMPACT OF THE STUDY: Planomicrobium sp. MSSA-10 might be used as potent bioinoculant to relieve pea plants from deleterious effects of salinity.

AB - AIMS: Volatile acidity (VA) production along with gene expression patterns, encoding enzymes involved in both acetic acid production and utilization, were investigated to relate gene expression patterns to the production of undesired VA during Icewine fermentation. METHODS AND RESULTS: Icewine juice and diluted Icewine juice were fermented using the Saccharomyces cerevisiae wine yeast K1 V1116. Acetic acid production increased sixfold during the Icewine fermentation vs the diluted juice condition, while ethyl acetate production increased 2.4-fold in the diluted fermentation relative to the Icewine. Microarray analysis profiled the transcriptional response of K1-V1116 under both conditions. ACS1 and ACS2 were downregulated 19.0-fold and 11.2-fold, respectively, in cells fermenting Icewine juice compared to diluted juice. ALD3 expression was upregulated 14.6 fold, and gene expressions involved in lipid and ergosterol synthesis decreased during Icewine fermentation. CONCLUSIONS: Decreased expression of ACS1 and ACS2 together with increased ALD3 expression contributes to the higher acetic acid and lower ethyl acetate levels generated by K1-V1116 fermenting under hyperosmotic stress. SIGNIFICANCE AND IMPACT OF THE STUDY: This work represents a more comprehensive understanding of how and why commercial wine yeast respond at the transcriptional and metabolic level during fermentation of Icewine juice, and how these responses contribute to increased acetic acid and decreased ethyl acetate production. PMID- 29444383 TI - Stemness and anti-cancer drug resistance in ATP-binding cassette subfamily G member 2 highly expressed pancreatic cancer is induced in 3D culture conditions. AB - The expression of ATP-binding cassette subfamily G member 2 (ABCG2) is related to tumorigenic cancer stem cells (CSC) in several cancers. However, the effects of ABCG2 on CSC-related malignant characteristics in pancreatic ductal adenocarcinoma (PDAC) are not well elucidated. In this study, we compared the characteristics of low (ABCG2-) and high (ABCG2+)-ABCG2-expressing PDAC cells after cell sorting. In adherent culture condition, human PDAC cells, PANC-1, contained approximately 10% ABCG2+ cell populations, and ABCG2+ cells displayed more and longer microvilli compared with ABCG2- cells. Unexpectedly, ABCG2+ cells did not show significant drug resistance against fluorouracil, gemcitabine and vincristine, and ABCG2- cells exhibited higher sphere formation ability and stemness marker expression than those of ABCG2+ cells. Cell growth and motility was greater in ABCG2- cells compared with ABCG2+ cells. In contrast, epithelial mesenchymal transition ability between ABCG2- and ABCG2+ cells was comparable. In 3D culture conditions, spheres derived from ABCG2- cells generated a large number of ABCG2+ cells, and the expression levels of stemness markers in these spheres were higher than spheres from ABCG2+ cells. Furthermore, spheres containing large populations of ABCG2+ cells exhibited high resistance against anti-cancer drugs presumably depending on ABCG2. ABCG2+ cells in PDAC in adherent culture are not correlated with stemness and malignant behaviors, but ABCG2+ cells derived from ABCG2- cells after sphere formation have stemness characteristics and anti-cancer drug resistance. These findings suggest that ABCG2- cells generate ABCG2+ cells and the malignant potential of ABCG2+ cells in PDAC varies depending on their environments. PMID- 29444385 TI - Improving near-peer teaching quality in anatomy by educating teaching assistants: An example from Sweden. AB - Peer-assisted learning has gained momentum in a variety of disciplines, including medical education. In Gothenburg, Sweden, medical students who have finished their compulsory anatomy courses have the option of working as teaching assistants (TAs). Teaching assistants provide small group teaching sessions as a complement to lectures given by faculty. Previously, TAs were left to handle the role as junior teachers by themselves, but since 2011, a continuation course in anatomy has been developed with the aim of providing the TAs better anatomy knowledge and guidance for teaching. The course was designed to comprise 7.5 ECTS credits (equivalent to 5 weeks of full-time studies), and today all TAs are required to take this course before undertaking their own teaching responsibilities. This study aims to compare course evaluations of TA teaching before and after the introduction of the anatomy continuation course, in order to understand how students perceived teaching performed by self-learned versus trained TAs. The results of this study demonstrate that there was a trend towards better teaching performed by trained TAs. The variability in rankings decreased significantly after the introduction of the continuation course. This was mainly due to an improvement among the TAs with the lowest levels of performance. In addition to comparing student rankings, TAs were interviewed regarding their experiences and perceptions within the continuation course. The course was generally positively regarded. The TAs described a sense of cohesion and appreciation since the institute invested in a course dedicated specifically for them. Anat Sci Educ 11: 403-409.

AB - The aims of this study were to determine the wood chemical composition of 25 species of Cactaceae and to relate the composition to their anatomical diversity. The hypothesis was that wood chemical components differ in relationship to their wood features. The results showed significant differences in wood chemical compounds across species and genera (P < 0.05). Pereskia had the highest percentage of lignin, whereas species of Coryphantha had the lowest; extractive compounds in water were highest for Echinocereus, Mammillaria, and Opuntia. Principal component analysis showed that lignin proportion separated the fibrous, dimorphic, and non-fibrous groups; additionally, the differences within each type of wood occurred because of the lignification of the vascular tissue and the type of wall thickening. Compared with other groups of species, the Cactaceae species with fibrous and dimorphic wood had a higher lignin percentage than did gymnosperms and Acer species. Lignin may confer special rigidity to tracheary elements to withstand desiccation without damage during adverse climatic conditions. PMID- 29444387 TI - The structure of the apo cAMP-binding domain of HCN4 - a stepping stone toward understanding the cAMP-dependent modulation of the hyperpolarization-activated cyclic-nucleotide-gated ion channels. AB - The hyperpolarization-activated cyclic-nucleotide-gated (HCN) ion channels control nerve impulse transmission and cardiac pacemaker activity. The modulation by cAMP is critical for the regulatory function of HCN in both neurons and cardiomyocytes, but the underlying mechanism is not fully understood. Here, we show how the structure of the apo cAMP-binding domain of the HCN4 isoform has contributed to a model for the cAMP-dependent modulation of the HCN ion-channel. This model recapitulates the structural and dynamical changes that occur along the thermodynamic cycle arising from the coupling of cAMP-binding and HCN self association equilibria. The proposed model addresses some of the questions previously open about the auto-inhibition of HCN and its cAMP-induced activation, while opening new opportunities for selectively targeting HCN through allosteric ligands. A remaining challenge is the investigation of HCN dimers and their regulatory role. Overcoming this challenge will require the integration of crystallography, cryo electron microscopy, NMR, electrophysiology and simulations. PMID- 29444388 TI - The virtual microscopy database-sharing digital microscope images for research and education. AB - Over the last 20 years, virtual microscopy has become the predominant modus of teaching the structural organization of cells, tissues, and organs, replacing the use of optical microscopes and glass slides in a traditional histology or pathology laboratory setting. Although virtual microscopy image files can easily be duplicated, creating them requires not only quality histological glass slides but also an expensive whole slide microscopic scanner and massive data storage devices. These resources are not available to all educators and researchers, especially at new institutions in developing countries. This leaves many schools without access to virtual microscopy resources. The Virtual Microscopy Database (VMD) is a new resource established to address this problem. It is a virtual image file-sharing website that allows researchers and educators easy access to a large repository of virtual histology and pathology image files. With the support from the American Association of Anatomists (Bethesda, MD) and MBF Bioscience Inc. (Williston, VT), registration and use of the VMD are currently free of charge. However, the VMD site is restricted to faculty and staff of research and educational institutions. Virtual Microscopy Database users can upload their own collection of virtual slide files, as well as view and download image files for their own non-profit educational and research purposes that have been deposited by other VMD clients.

AB - Anatomy is fundamental to clinical practice, is considered a rite of passage in becoming a physician and is key to professional identity formation. The anatomy course that began the medical curriculum at the University of New Mexico School of Medicine was recently dissolved to address content and process gaps in the pre clinical curriculum. Anatomy was integrated into the organ system blocks to make room for new courses to address content gaps. Previous reports of anatomy integration document more positive attitudes and perceptions to teaching anatomy in context, as compared to an independent course. The current prospective study compared two medical student cohorts to determine the effects of teaching anatomy in and out of context on the cognitive and affective domains of learning. In a pre, post, and follow-up design, methods included content assessments, confidence probes, and attitude surveys informed by focus groups. Results indicated that anatomical knowledge and student confidence was gained and mastered in both curricula. Initial acquisition of content was higher in the integrated curriculum, but not maintained. Students in the integrated curriculum displayed a different relationship to learning anatomy, appearing more concerned with their personal progression than with the connection of anatomy to medical practice or patient care. These students also agreed less with statements related to working in teams, reflective practices and professional identity formation. Further studies will determine if this difference will diminish with continued exposure to anatomy and may inform future curricular adjustments. Anat Sci Educ.

AB - Alpha 2 agonists are appreciated drugs designed for the peri-operative period, because of their anxiolytic, sedative and analgesic properties. However, they are usually avoided during scoliosis surgery, a longlasting major procedure involving healthy patients, because of their potential effects on Somatosensory and Motorevoked potentials. The absence ofrecommendations suggests that their effects on evoked potentials are still unclear. Thus, we tried in this narrative review to identify the literature representative of the effects of clonidine and dexmedetomidine on evoked potentials, on human beings, published between 1988 and 2015 in English or French, using GOOGLE SCHOLAR and PUBMED. Paucity of literature prevented any conclusion about Clonidine's effects on evoked potentials, but no data suggested a noxious effect of Clonidine on evoked potentials, used in oral premedication (300 MUg) or during the procedure (2 to 5 MUg/kg). If literature was more extensive for dexmedetomidine, studies were still controversial. Although the majority of the studies did not find statistically significant differences concerning the effects of this drug on evoked potentials (loading dose of 0.3 to 1 MUg/ kg followed by continuous infusion of 0.3 to 0.8 MUg/kg/h), 2 case reports and 2 studies described substantial decreases. However, dexmedetomidine's shorter duration of action allowed a quick return to basal situation within an hour. In conclusion, more studies are needed in order to evaluate the effects of alpha 2 agonists on evoked potentials and to assess the safety of their use in this setting. PMID- 29444391 TI - High Flow Nasal Cannula oxygenation for adult patients in the ICU: a literature review. AB - Oxygenation using High Flow Nasal Cannula (HFNC) was initially described in neonatal medicine, but, gradually, its use has extended to adult patients. The efficacy of the device has been linked to higher flows of oxygen delivered to the patients, air tract humidification, alveolar recruitment through a positive end expiratory pressure (PEEP) effect, prevention of nasopharyngeal collapse, and dead-space washout. Beside the fact that HFNC is a non-invasive way of delivering oxygen to ICU patients, and is well tolerated, results from various clinical trials tend to show positive outcomes for patients presenting with acute hypoxemic respiratory failure (AHRF), during intubation, or during the post extubation period. However, controversy arose from recent publications, and larger trials are still required to clarify the position of HFNC in the ICU, and help define the subgroups of patients presenting with AHRF that are most likely to benefit from HFNC therapy. PMID- 29444392 TI - Intraoperative cerebral hypoperfusion and electroencephalogram suppression resulting in neurological complications after cardiac surgery : the need for an in depth investigation. AB - Reports on the demographic profile of older populations estimate that, in 2050, 19 countries will have at least 10% of their population aged 80 years or more. Many high risk elderly patients undergo cardiac surgery. In addition, advanced age has been shown to be a strong predictor of adverse neurological outcome. Despite sig- nificant improvements achieved in the perioperative care of cardiac surgical patients, neurological complications remain a global health issue. Recent findings have pointed out that cerebral hypoperfusion and too deep levels of anesthesia are major sources of adverse neurological outcomes. Cerebral near in-frared spectroscopy provides information about cerebral perfusion non invasively, and is increasingly used. Depth of anesthesia is evaluated using monitors that are based on processed electroencephalogram. This non-systematic review focuses on the results of studies performed with each monitor separately, and the need for a combined evaluation of their utility and eventual impact on neurological outcomes. The use of a combined cerebral monitoring strategy based on the two aforementioned monitors is proposed in order to optimize cerebral outcomes. PMID- 29444393 TI - Two different techniques of facial mask induction of anesthesia in children provide identical intubation conditions despite different anesthetic depth. AB - BACKGROUND: Sevoflurane induction in chil- dren is performed using different techniques. Constricted, centered, and symmetrical pupils (CCSP) are classically the endpoint to be achieved before laryngoscopy is performed. OBJECTIVES: We investigated whether two different inhalation induction techniques with the same clinical end- point provided similar intubating conditions and comparable depth of anesthesia as assessed by the Bispectral Index (BIS). METHODS: Following IRB approval, and informed parental consent, 20 children were recruited. They were sched- uled for general anesthesia with tracheal intubation, and randomly assigned to Group 1, where the practitioner used 6% inspired sevoflurane in 50% 02/N20, and no manually assisted ventilation, or Group 2, where inspired sevoflurane was 8% in 50% 02/N20, and ventilation was manually supported upon loss of consciousness. BIS values were blinded. Laryngoscopy was performed after CCSP. Intubation conditions scoring was based on jaw relaxation (mobile = 1, partially mobile = 2, fixed = 3), position of vocal cords (open = 1, half-closed = 2, closed = 3), and cough (no cough = 1, 1 or 2 coughing efforts = 2, persistent coughing = 3). A total score > 3 corresponded to non-optimal conditions. RESULTS: Upon CCSP, BIS values were significantly lower in Group 1 [mean (SD) : 30 (8) - 48 (18), p <0.001], despite significantly higher end-tidal sevoflurane concentration in Group 2 [mean (SD) : 5.0 (0.7) - 6.2 (0.5) ; p <0.001]. Time to CCSP was slightly shorter in Group 2. Intubation conditions were always optimal except for one patient of Group 1. DISCUSSION: Both induction techniques achieve good intubating conditions. Possible explanations for the between-group BIS difference include variable appreciation of the CCSP endpoint, different induction lengths or sevoflurane equilibration times, or sevoflurane induced increase in electroencephalogram power. A better indicator of the best time to intubate is needed to avoid too deep anesthesia in children. PMID- 29444394 TI - Hearing loss after spinal anesthesia : A comparative prospective randomized cohort study. AB - OBJECTIVE: In this comparative randomized cohort study, we aimed at evaluating the occurrence of sensorineural hearing loss after general and spinal anesthesia using both subjective and objective tests. MATERIAL AND METHODS: Fifty patients scheduled for elective cesarean section were approached, of which 21 patients received spinal anesthesia (group S), and 16 patients received general anesthesia (group G). In group S, a 27 G pencil point spinal needle was used. Pure tone audiometry and Distortion Product OtoAcoustic Emissions (DPOAE) were performed before and 48 hours after surgery. RESULTS: No between-group significant difference in pre and postoperative audiometric hearing threshold and pure tone average value were noticed, as well as in pre and postoperative DPOAE amplitude and signal-to-noise ratio (SNR). CONCLUSION: In this study, we did not observe any hearing loss after cesarean section under general or spinal anesthesia. Using the non-traumatic 27 gauge pencil point needle for performing spinal anesthesia does not seem to be associated with a risk of hearing loss, similarly to general anesthesia. PMID- 29444395 TI - A cardiac arrest following the administration of succinylcholine. AB - A twenty-three year old woman, admitted to the intensive care unit (ICU) with a diagnosis of menin- gitis and associated lower limb ischemia suffered a car- diac arrest, due to extreme hyperkalemia, following the administration of succinylcholine in order to replace an endo-tracheal tube. After prolonged cardiopulmonary resuscitation (CPR) lasting 45 minutes, during which 8 mg of epinephrine was administered, cardiac output was restored. Four weeks later the patient left intensive care, having made a full recovery with no neurological deficit. The following case highlights the risks of succinylcholine in the septic patient and that prolonged resuscitation can have a succesfiil outcome. PMID- 29444396 TI - Integrating a Silicon Solar Cell with a Triboelectric Nanogenerator via a Mutual Electrode for Harvesting Energy from Sunlight and Raindrops. AB - Solar cells, as promising devices for converting light into electricity, have a dramatically reduced performance on rainy days. Here, an energy harvesting structure that integrates a solar cell and a triboelectric nanogenerator (TENG) device is built to realize power generation from both sunlight and raindrops. A heterojunction silicon (Si) solar cell is integrated with a TENG by a mutual electrode of a poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) film. Regarding the solar cell, imprinted PEDOT:PSS is used to reduce light reflection, which leads to an enhanced short-circuit current density. A single-electrode-mode water-drop TENG on the solar cell is built by combining imprinted polydimethylsiloxane (PDMS) as a triboelectric material combined with a PEDOT:PSS layer as an electrode. The increasing contact area between the imprinted PDMS and water drops greatly improves the output of the TENG with a peak short-circuit current of ~33.0 nA and a peak open-circuit voltage of ~2.14 V, respectively. The hybrid energy harvesting system integrated electrode configuration can combine the advantages of high current level of a solar cell and high voltage of a TENG device, promising an efficient approach to collect energy from the environment in different weather conditions. PMID- 29444397 TI - Partner-Specific Prediction of Protein-Dimer Stability from Unbound Structure of Monomer. AB - Protein complexes play deterministic roles in live entities in sensing, compiling, controlling, and responding to external and internal stimuli. Thermodynamic stability is an important property of protein complexes; having knowledge about complex stability helps us to understand the basics of protein assembly-related diseases and the mechanism of protein assembly clearly. Enormous protein-protein interactions, detected by high-throughput methods, necessitate finding fast methods for predicting the stability of protein assemblies in a quantitative and qualitative manner. The existing methods of predicting complex stability need knowledge about the three-dimensional (3D) structure of the intended protein complex. Here, we introduce a new method for predicting dissociation free energy of subunits by analyzing the structural and topological properties of a protein binding patch on a single subunit of the desired protein complex. The method needs the 3D structure of just one subunit and the information about the position of the intended binding site on the surface of that subunit to predict dimer stability in a classwise manner. The patterns of structural and topological properties of a protein binding patch are decoded by recurrence quantification analysis. Nonparametric discrimination is then utilized to predict the stability class of the intended dimer with accuracy greater than 85%. PMID- 29444398 TI - The Importance of Cell Shape Sampling To Accurately Predict Flexibility in Metal Organic Frameworks. AB - In this work, the influence of cell shape sampling on the predicted stability of the different metastable phases in flexible metal-organic frameworks at finite temperatures is investigated. The influence on the free energy by neglecting cell shape sampling is quantified for the prototypical MIL-53(Al) and the topical DUT 49(Cu). This goal is achieved by constructing free energy profiles in ensembles either in which the phase space associated with the cell shape is sampled explicitly or in which the cell shape is kept fixed. When neglecting cell shape sampling, thermodynamic integration of the hydrostatic pressure yields unreliable free energy profiles that depend on the choice of the fixed cell shape. In this work, we extend the thermodynamic integration procedure via the introduction of a generalized pressure, derived from the Lagrangian strain tensor and the second Piola-Kirchhoff tensor. Using this generalized procedure, the dependence on the unit cell shape can be eliminated, and the inaccuracy in free energy stemming from the lack of cell shape sampling can be uniquely quantified. Finally, it is shown that the inaccuracy in free energy when fixing the cell shape at room temperature stems mainly from entropic contributions for both MIL-53(Al) and DUT 49(Cu). PMID- 29444399 TI - Chemical Understanding of the Limited Site-Specificity in Molecular Inner-Shell Photofragmentation. AB - In many cases fragmentation of molecules upon inner-shell ionization is very unspecific with respect to the initially localized ionization site. Often this finding is interpreted in terms of an equilibration of internal energy into vibrational degrees of freedom after Auger decay. We investigate the X-ray photofragmentation of ethyl trifluoroacetate upon core electron ionization at environmentally distinct carbon sites using photoelectron-photoion-photoion coincidence measurements and ab initio electronic structure calculations. For all four carbon ionization sites, the Auger decay weakens the same bonds and transfers the two charges to opposite ends of the molecule, which leads to a rapid dissociation into three fragments, followed by further fragmentation steps. The lack of site specificity is attributed to the character of the dicationic electronic states after Auger decay instead of a fast equilibration of internal energy. PMID- 29444400 TI - Chiral Nickel(II) Complex Catalyzed Enantioselective Doyle-Kirmse Reaction of alpha-Diazo Pyrazoleamides. AB - Although high enantioselectivity of [2,3]-sigmatropic rearrangement of sulfonium ylides (Doyle-Kirmse reaction) has proven surprisingly elusive using classic chiral Rh(II) and Cu(I) catalysts, in principle it is due to the difficulty in fine discrimination of the heterotopic lone pairs of sulfur and chirality inversion at sulfur of sulfonium ylides. Here, we show that the synergistic merger of new alpha-diazo pyrazoleamides and a chiral N, N'-dioxide-nickel(II) complex catalyst enables a highly enantioselective Doyle-Kirmse reaction. The pyrazoleamide substituent serves as both an activating and a directing group for the ready formation of a metal-carbene- and Lewis-acid-bonded ylide intermediate in the assistance of a dual-tasking nickel(II) complex. An alternative chiral Lewis-acid-bonded ylide pathway greatly improves the product enantiopurity even for the reaction of a symmetric diallylsulfane. The majority of transformations over a series of aryl- or vinyl-substituted alpha-diazo pyrazoleamindes and sulfides proceed rapidly (within 5-20 min in most cases) with excellent results (up to 99% yield and 96% ee), providing a breakthrough in enantioselective Doyle Kirmse reaction. PMID- 29444401 TI - Modulating Electrocatalysis on Graphene Heterostructures: Physically Impermeable Yet Electronically Transparent Electrodes. AB - The electronic properties and extreme thinness of graphene make it an attractive platform for exploring electrochemical interactions across dissimilar environments. Here, we report on the systematic tuning of the electrocatalytic activity toward the oxygen reduction reaction (ORR) via heterostructures formed by graphene modified with a metal underlayer and an adlayer consisting of a molecular catalyst. Systematic voltammetric testing and electrochemical imaging of patterned electrodes allowed us to confidently probe modifications on the ORR mechanisms and overpotential. We found that the surface configuration largely determined the ORR mechanism, with adlayers of porphyrin molecular catalysts displaying a higher activity for the 2e- pathway than the bare basal plane of graphene. Surprisingly, however, the underlayer material contributed substantially to lower the activation potential for the ORR in the order Pt > Au > SiO x, strongly suggesting the involvement of the solution-excluded metal on the reaction. Computational investigations suggest that ORR enhancements originate from permeation of metal d-subshell electrons through the graphene layer. In addition, these physically impermeable but electronically transparent electrodes displayed tolerance to cyanide poisoning and stability toward long term cycling, highlighting graphene as an effective protection layer of noble metal while enabling electrochemical interactions. This work has implications in the mechanistic understanding of 2D materials and core-shell-type heterostructures for electrocatalytic reactions. PMID- 29444402 TI - Solid-Phase Synthesis of Pyrrole Derivatives through a Multicomponent Reaction Involving Lys-Containing Peptides. AB - The synthesis of pyrroles has received considerable attention because of their biological and pharmaceutical activities. Herein we describe a solid-phase multicomponent reaction that utilizes Lys as a N donor, beta-nitrostyrenes, 1,3 dicarbonyl compounds, and FeCl3 as an easily accessible catalyst under microwave irradiation to afford the subsequent pyrrole derivatives in high conversions. The strategy combines three of the most powerful tools in modern synthetic chemistry: the solid-phase mode, microwave activation, and a multicomponent reaction. The excellent results in terms of rapidity, versatility, and purity obtained herein support once again that this combined strategy is efficient for gaining chemical diversity. PMID- 29444404 TI - Polarizable Density Embedding Coupled Cluster Method. AB - We present the theory and implementation of the polarizable density embedding (PDE) model in combination with coupled cluster (CC) theory (PDE-CC). This model has been implemented in the Dalton quantum chemistry program by adapting the CC code to the polarizable embedding library ( PElib). In the PDE-CC method, the smaller, but chemically important core region is described with a high-level CC method. The environment surrounding the core region can be separated into two levels of description: an inner and an outer region. The effect of the inner region on the core region is described by an embedding potential consisting of a set of fragment densities obtained from calculations on isolated fragments with a quantum-chemistry method such as Hartree-Fock (HF) or Kohn-Sham density functional theory (KS-DFT) and dressed with a set of atom-centered anisotropic dipole-dipole polarizabilities. The outer region consists of distributed atom centered multipoles and polarizabilities, i.e., in the same way as in the polarizable embedding (PE) model. The PDE-CC method contains embedding potential operators that account for the electrostatic and polarization interactions between the core region and the environment, as well as for nonelectrostatic (also known as Pauli and exchange) repulsion. All environmental effects are included through one-electron operators and account very efficiently for the response of the environment due to the change in the electron density of the core region, e.g., upon an electronic transition. PMID- 29444403 TI - Plant Villin Headpiece Domain Demonstrates a Novel Surface Charge Pattern and High Affinity for F-Actin. AB - Plants utilize multiple isoforms of villin, an F-actin regulating protein with an N-terminal gelsolin-like core and a distinct C-terminal headpiece domain. Unlike their vertebrate homologues, plant villins have a much longer linker polypeptide connecting the core and headpiece. Moreover, the linker-headpiece connection region in plant villins lacks sequence homology to the vertebrate villin sequences. It is unknown to what extent the plant villin headpiece structure and function resemble those of the well-studied vertebrate counterparts. Here we present the first solution NMR structure and backbone dynamics characterization of a headpiece from plants, villin isoform 4 from Arabidopsis thaliana. The villin 4 headpiece is a 63-residue domain (V4HP63) that adopts a typical headpiece fold with an aromatics core and a tryptophan-centered hydrophobic cap within its C-terminal subdomain. However, V4HP63 has a distinct N-terminal subdomain fold as well as a novel, high mobility loop due to the insertion of serine residue in the canonical sequence that follows the variable length loop in headpiece sequences. The domain binds actin filaments with micromolar affinity, like the vertebrate analogues. However, the V4HP63 surface charge pattern is novel and lacks certain features previously thought necessary for high-affinity F actin binding. Utilizing the updated criteria for strong F-actin binding, we predict that the headpiece domains of all other villin isoforms in A. thaliana have high affinity for F-actin. PMID- 29444405 TI - Fullerene-Functionalized Monolayer-Protected Silver Clusters: [Ag29(BDT)12(C60) n]3- ( n = 1-9). AB - We report the formation of supramolecular adducts between monolayer-protected noble metal nanoclusters and fullerenes, specifically focusing on a well-known silver cluster, [Ag29(BDT)12]3-, where BDT is 1,3-benzenedithiol. We demonstrate that C60 molecules link with the cluster at specific locations and protect the fragile cluster core, enhancing the stability of the cluster. A combination of studies including UV-vis, high-resolution electrospray ionization mass spectrometry, collision-induced dissociation, and nuclear magnetic resonance spectroscopy revealed structural details of the fullerene-functionalized clusters, [Ag29(BDT)12(C60) n]3- ( n = 1-9). Density functional theory (DFT) calculations and molecular docking simulations affirm compatibility between the cluster and C60, resulting in its attachment at specific positions on the surface of the cluster, stabilized mainly by pi-pi and van der Waals interactions. The structures have also been confirmed from ion mobility mass spectrometry by comparing the experimental collision cross sections (CCSs) with the theoretical CCSs of the DFT-optimized structures. The gradual evolution of the structures with an increase in the number of fullerene attachments to the cluster has been investigated. Whereas the structure for n = 4 is tetrahedral, that of n = 8 is a distorted cube with a cluster at the center and fullerenes at the vertices. Another fullerene, C70, also exhibited similar behavior. Modified clusters are expected to show interesting properties. PMID- 29444406 TI - Limononic Acid Oxidation by Hydroxyl Radicals and Ozone in the Aqueous Phase. AB - Kinetics and mechanism of limononic acid (3-isopropenyl-6-oxoheptanoic acid, LA) oxidation by hydroxyl radicals (OH) and ozone (O3) were studied in the aqueous phase at 298 +/- 2 K. These reactions were investigated using liquid chromatography coupled to the electrospray ionization and quadrupole tandem mass spectrometry (LC-ESI/MS/MS). The rate coefficients determined for LA + OH reaction were: 1.3 +/- 0.3 * 1010 M-1 s-1 at pH = 2 and 5.7 +/- 0.6 * 109 M-1 s-1 at pH = 10. The rate coefficient determined for LA ozonolysis was 4.2 +/- 0.2 * 104 M-1 s-1 at pH = 2. The calculated Henry's law constant (H) for LA was ca. 6.3 * 106 M * atm-1, thereby indicating that in fogs and clouds with LWC = 0.3-0.5 g * m-3 LA will reside entirely in the aqueous phase. Calculated atmospheric lifetimes due to reaction with OH and O3 strongly indicate that aqueous-phase oxidation can be important for LA under realistic atmospheric conditions. Under acidic conditions, the aqueous-phase oxidation of LA by OH will dominate over reaction with O3, whereas the opposite is more likely when pH >= 4.5. The aqueous phase oxidation of LA produced keto-limononic acid and a number of low-volatility products, such as hydroperoxy-LA and alpha-hydroxyhydroperoxides. PMID- 29444407 TI - Phase-Tunable Josephson Thermal Router. AB - A fundamental aspect of electronics is the ability to distribute a charge current among different terminals. On the other hand, despite the great interest in dissipation, storage, and conversion of heat in solid state structures, the control of thermal currents at the nanoscale is still in its infancy. Here, we show the experimental realization of a phase-tunable thermal router able to control the spatial distribution of an incoming heat current, thus providing the possibility of tuning the electronic temperatures of two output terminals. This ability is obtained thanks to a direct current superconducting quantum interference device (dc SQUID), which can tune the coherent component of the electronic heat currents flowing through its Josephson junctions. By varying the external magnetic flux and the bath temperature, the SQUID allows us to regulate the size and the direction of the thermal gradient between two drain electrodes. Our results offer new opportunities for all microcircuits requiring an accurate energy management, including electronic coolers, quantum information architectures, and thermal logic components. PMID- 29444408 TI - Simple Models for Difficult Electronic Excitations. AB - We present a single-determinant approach to three challenging topics in the chemistry of excited states: double excitations, charge-transfer states, and conical intersections. The results are obtained by using the Initial Maximum Overlap Method (IMOM) which is a modified version of the Maximum Overlap Method (MOM). The new algorithm converges better than the original, especially for these difficult problems. By considering several case studies, we show that a single determinant framework provides a simple and accurate alternative for modeling excited states in cases where other low-cost methods, such as CIS and TD-DFT, either perform poorly or fail completely. PMID- 29444409 TI - Sequence-Specific Self-Assembly of Positive and Negative Monomers with Cucurbit[8]uril Linkers. AB - The self-assembly into dynamic oligomers of Cucurbit[8]uril (CB[8]), a positive ditopic Ir(III) bis-terpyridine complex, and a negative ditopic Fe(II) bis terpyridine complex flanked by four butyrate side chains was assessed to answer a seemingly straightforward question: does CB[8] adopt a social self-sorting pattern by encapsulating both positive and negative units into a heteroternary complex? We showed that this is indeed the case, with CB[8] linking a positive Ir unit to a neighboring negative Fe unit whenever possible. Furthermore, the solubility of the dynamic oligomers was significantly affected by their sequence; upon addition of 0.6-1.2 equiv of positive Ir oligomer to its negative Fe counterpart, the predominant assembly present in solution was a mixed oligomer with a (Fe-Ir-Ir-) n sequence. Weak interactions between the negative butyrate side chains and the partially positive outer wall of CB[7] were also identified by two-dimensional nuclear magnetic resonance techniques, and resulted in a negative p Ka shift (0.10 p Ka unit) for the terminal carboxylic groups. PMID- 29444410 TI - Enhanced Ion Transmission Efficiency up to m/ z 24 000 for MALDI Protein Imaging Mass Spectrometry. AB - The molecular identification of species of interest is an important part of an imaging mass spectrometry (IMS) experiment. The high resolution accurate mass capabilities of Fourier transform ion cyclotron resonance mass spectrometry (FT ICR MS) have recently been shown to facilitate the identification of proteins in matrix-assisted laser desorption/ionization (MALDI) IMS. However, these experiments are typically limited to proteins giving rise to ions of relatively low m/ z due to difficulties transmitting and measuring large molecular weight ions of low charge states. Herein we have modified the source gas manifold of a commercial MALDI FT-ICR MS to regulate the gas flow and pressure to maximize the transmission of large m/ z protein ions through the ion funnel region of the instrument. By minimizing the contribution of off-axis gas disruption to ion focusing and maximizing the effective potential wall confining the ions through pressure optimization, the signal-to-noise ratios (S/N) of most protein species were improved by roughly 1 order of magnitude compared to normal source conditions. These modifications enabled the detection of protein standards up to m/ z 24 000 and the detection of proteins from tissue up to m/ z 22 000 with good S/N, roughly doubling the mass range for which high quality protein ion images from rat brain and kidney tissue could be produced. Due to the long time-domain transients (>4 s) required to isotopically resolve high m/ z proteins, we have used these data as part of an FT-ICR IMS-microscopy data-driven image fusion workflow to produce estimated protein images with both high mass and high spatial resolutions.

PMID- 29444412 TI - Heart rate variability responses to acute and repeated postexercise sauna in trained cyclists. AB - Short- to medium-term (i.e., 4-14 days) heating protocols induce physiological adaptations including improved cardiac autonomic modulations, as assessed using heart rate variability, which may contribute to greater exercise performance. Whether similar cardiac autonomic changes occur during an intense heating protocol (sauna) reported to increase plasma volume in athletes remains to be confirmed. This study examined changes in heart rate and its variability during a single extreme heat (sauna) exposure and repeated exposures in athletes. Six well trained male cyclists undertook sauna bathing (30 min, 87 degrees C, 11% relative humidity) immediately after normal training over 10 consecutive days. Heart rate recordings were obtained during each sauna bout. Heart rate and its variability (natural logarithm of root mean square of successive differences, lnRMSSD) were analysed during 10-min periods within the first bout, and changes in heart rate and lnRMSSD were analysed during each bout via magnitude-based inferences. During the first sauna bout, heart rate was almost certainly increased (~32%, effect size 1.68) and lnRMSSD was almost certainly reduced (~62%, effect size -5.21) from the first to the last 10-min period, indicating reduced parasympathetic and (or) enhanced sympathetic modulations. Acute exposure to extreme heat stress via sauna produced alterations in heart rate and cardiac autonomic modulations with successive postexercise heat exposures producing unclear changes over a 10-day period. The physiological benefits of intense heating via sauna on cardiac control in athletes remain to be elucidated. PMID- 29444413 TI - Involvement of Alveolar Epithelial Cell Necroptosis in Idiopathic Pulmonary Fibrosis Pathogenesis. AB - Alveolar epithelial cell (AEC) injury leading to cell death is involved in the process of fibrosis development during idiopathic pulmonary fibrosis (IPF). Among regulated/programmed cell death, the excessive apoptosis of AECs has been widely implicated in IPF pathogenesis. Necroptosis is a type of regulated/programmed necrosis. A multiprotein complex composed of receptor-interacting protein kinase (RIPK)-1 and -3 plays a key regulatory role in initiating necroptosis. Although necroptosis participates in disease pathogeneses through the release of damage associated molecular patterns, its association with IPF progression remains elusive. In this study, we attempted to illuminate the involvement of RIPK3 regulated necroptosis in IPF pathogenesis. IPF lung tissues were used to detect necroptosis, and the role of RIPK3 was determined using cell culturing models of AECs. Lung fibrosis models of bleomycin (BLM) treatment were also used. RIPK3 expression levels were increased in IPF lungs, and both apoptosis and necroptosis were detected mainly in AECs. Necrostatin-1 and RIPK3 knockout experiments in AECs revealed the participation of necroptosis in BLM and hydrogen peroxide induced cell death. BLM treatment induced RIPK3 expression in AECs and increased high-mobility group box 1 and IL-1beta levels in mouse lungs. The efficient attenuation of BLM-induced lung inflammation and fibrosis was determined in RIPK3 knockout mice and by necrostatin-1 with a concomitant reduction in high-mobility group box 1 and IL-1beta. RIPK3-regulated necroptosis in AECs is involved in the mechanism of lung fibrosis development through the release of damage-associated molecular patterns as part of the pathogenic sequence of IPF. PMID- 29444414 TI - No individual or combined effects of caffeine and beetroot-juice supplementation during submaximal or maximal running. AB - Dietary supplements such as caffeine and beetroot juice are used by athletes in an attempt to optimize performance and therefore gain an advantage in competition. The aim of this study was to investigate the individual and combined effects of caffeine and beetroot-juice supplementation during submaximal and maximal treadmill running. Seven males (maximal oxygen uptake: 59.0 +/- 2.9 mL.kg 1.min-1) and 2 females (maximal oxygen uptake: 53.1 +/- 11.4 mL.kg-1.min-1) performed a preliminary trial followed by 4 experimental test sessions. Each test session consisted of two 5-min submaximal running bouts (at ~70% and 80% of maximal oxygen uptake) and a maximal 1-km time trial (TT) in a laboratory. Participants ingested 70 mL of concentrated beetroot juice containing either 7.3 mmol of nitrate (BR) or no nitrate (PBR) 2.5 h prior to each test session, then either caffeine (C) at 4.8 +/- 0.4 (4.3-5.6) mg/kg of body mass or a caffeine placebo (PC) 45 min before each test session. The 4 test sessions (BR-C, BR-PC, PBR-C, and PBR-PC) were presented in a counterbalanced and double-blind manner. No significant differences were identified between the 4 interventions regarding relative oxygen uptake, running economy, respiratory exchange ratio, heart rate (HR), or rating of perceived exertion (RPE) at the 2 submaximal intensities (P > 0.05). Moreover, there were no significant differences in performance, maximum HR, peak blood lactate concentration, or RPE during the maximal TT when comparing the interventions (P > 0.05). In conclusion, no beneficial effects of supplementing with typical doses of caffeine, beetroot juice, or a combination of the two were observed for physiological, perceptual, or performance responses during submaximal or maximal treadmill running exercise. PMID- 29444415 TI - BACE1 Inhibition by Genistein: Biological Evaluation, Kinetic Analysis, and Molecular Docking Simulation. AB - beta-site amyloid precursor protein cleaving enzyme 1 (BACE1) plays a role in generating amyloid beta (Abeta), thus playing a major part early in the pathogenesis of Alzheimer's disease (AD). BACE1 has emerged as a crucial therapeutic target for decreasing the Abeta concentration in the AD brain. To explore natural BACE1 inhibitors, the present study concentrated on isoflavones, including genistein, formononetin, glycitein, daidzein, and puerarin. In this study, in vitro anti-AD activities were assessed using BACE1 inhibition assays, as well as enzyme kinetic predictions. Molecular docking analysis was applied to design potential BACE1 inhibitors. Among the major isoflavones, genistein exerted a notable BACE1 inhibition through reversible noncompetitive mechanism, while other compounds were less potent against BACE1. The docking study revealed that genistein had negative binding energy (-8.5 kcal/mol) and was stably positioned in the allosteric domains of BACE1 residues. It interacted with important amino acid residues in BACE1, such as ASN37, GLN73, and TRP76, through hydrogen bonding. The results suggested that genistein may be beneficial for preventing and/or treating AD. Furthermore, it may provide potential guidelines for the design of new BACE1 inhibitors.

AB - Ultrastructural changes in the cell envelope of the yeast Yarrowia lipolytica as a stress response were examined using electron microscopy. The formation of new cellular surface structures, including membrane vesicles, pore channels, and wall surface globules, were shown for the first time under conditions of oxidative (endogenous and exogenous) or thermal stress. This demonstrates once again that under stress conditions the microorganisms reveal properties previously unknown for them. Particularly noteworthy is the accumulation of silicon in the surface globules, which was revealed by X-ray microanalysis of the elemental composition of thin sections of cells. A multilayered plasmalemma instead of a 3-layered one is also characteristic for stressed cells. The envelope modifications above were observed only as a stress response and were not detected in stationary-growth phase yeast cells that assume different physiological states. A decrease in the intracellular level of cAMP allows us to assume that a common factor activates defensive mechanisms thus explaining the similarity of the response under different stress conditions. The data presented not only enable visualization of the yeast stress response and add to our awareness of the diversity of adaptive reactions, but they also raise questions about the interrelations of the stress phenomena and their functional necessity in the cell. PMID- 29444417 TI - A study on the regenerative effect of platelet-rich plasma on experimentally induced hepatic damage in albino rats. AB - Hepatic fibrosis is a worldwide health problem with significant morbidity and mortality. Currently, there is no effective therapy for hepatic fibrosis. The present study was aimed to evaluate the possible regenerative effect of platelet rich plasma (PRP) against thioacetamide (TAA)-induced hepatic damage. Eighty albino rats were included; 40 were used for PRP preparation and 40 were randomly divided into 4 groups: group I (control group); group II (PRP control); group III (TAA-intoxicated by a dose of 200 mg/kg body mass, intraperitoneally, twice weekly for 7 weeks), and group IV (TAA intoxicated + PRP treated). Macrophage inflammatory protein-1alpha (MIP-1alpha) and cyclic adenosine monophosphate (cAMP) were immunoassayed in addition to peroxinitrite level, NADPH-quinone oxidoreductase-1 (NQO1) enzyme activity, and liver function. PRP treatment showed significant improvement in hepatic function, and decreased MIP-1alpha and peroxinitrite levels. Meanwhile, significant increase in NQO1 enzyme activity and cAMP level were observed. The histopathological results confirmed the laboratory results with improvement of hepatic architecture except for some inflammatory cellular infiltrates. This study shows that PRP has the ability to protect against TAA-induced liver damage, possibly by improving redox status, liver histopathological architecture, and disruption of the inflammatory and fibrotic response induced by TAA. PMID- 29444418 TI - Circuitry Rewiring Directly Couples Competence to Predation in the Gut Dweller Streptococcus salivarius. AB - Small distortions in transcriptional networks might lead to drastic phenotypical changes, especially in cellular developmental programs such as competence for natural transformation. Here, we report a pervasive circuitry rewiring for competence and predation interplay in commensal streptococci. Canonically, in streptococci paradigms such as Streptococcus pneumoniae and Streptococcus mutans, the pheromone-based two-component system BlpRH is a central node that orchestrates the production of antimicrobial compounds (bacteriocins) and incorporates signal from the competence activation cascade. However, the human commensal Streptococcus salivarius does not contain a functional BlpRH pair, while the competence signaling system ComRS directly couples bacteriocin production and competence commitment. This network shortcut might underlie an optimal adaptation against microbial competitors and explain the high prevalence of S. salivarius in the human digestive tract. Moreover, the broad spectrum of bacteriocin activity against pathogenic bacteria showcases the commensal and genetically tractable S. salivarius species as a user-friendly model for competence and bacterial predation. PMID- 29444419 TI - Pak1 Kinase Maintains Apical Membrane Identity in Epithelia. AB - Epithelial cells are polarized along their apical-basal axis by the action of the small GTPase Cdc42, which is known to activate the aPKC kinase at the apical domain. However, loss of aPKC kinase activity was reported to have only mild effects on epithelial cell polarity. Here, we show that Cdc42 also activates a second kinase, Pak1, to specify apical domain identity in Drosophila and mammalian epithelia. aPKC and Pak1 phosphorylate an overlapping set of polarity substrates in kinase assays. Inactivating both aPKC kinase activity and the Pak1 kinase leads to a complete loss of epithelial polarity and morphology, with cells losing markers of apical polarization such as Crumbs, Par3/Bazooka, or ZO-1. This function of Pak1 downstream of Cdc42 is distinct from its role in regulating integrins or E-cadherin. Our results define a conserved dual-kinase mechanism for the control of apical membrane identity in epithelia. PMID- 29444420 TI - Perineurial Barrier Glia Physically Respond to Alcohol in an Akap200-Dependent Manner to Promote Tolerance. AB - Ethanol is the most common drug of abuse. It exerts its behavioral effects by acting on widespread neural circuits; however, its impact on glial cells is less understood. We show that Drosophila perineurial glia are critical for ethanol tolerance, a simple form of behavioral plasticity. The perineurial glia form the continuous outer cellular layer of the blood-brain barrier and are the interface between the brain and the circulation. Ethanol tolerance development requires the A kinase anchoring protein Akap200 specifically in perineurial glia. Akap200 tightly coordinates protein kinase A, actin, and calcium signaling at the membrane to control tolerance. Furthermore, ethanol causes a structural remodeling of the actin cytoskeleton and perineurial membrane topology in an Akap200-dependent manner, without disrupting classical barrier functions. Our findings reveal an active molecular signaling process in the cells at the blood brain interface that permits a form of behavioral plasticity induced by ethanol. PMID- 29444421 TI - Chloroplast Signaling Gates Thermotolerance in Arabidopsis. AB - Temperature is a key environmental variable influencing plant growth and survival. Protection against high temperature stress in eukaryotes is coordinated by heat shock factors (HSFs), transcription factors that activate the expression of protective chaperones such as HEAT SHOCK PROTEIN 70 (HSP70); however, the pathway by which temperature is sensed and integrated with other environmental signals into adaptive responses is not well understood. Plants are exposed to considerable diurnal variation in temperature, and we have found that there is diurnal variation in thermotolerance in Arabidopsis thaliana, with maximal thermotolerance coinciding with higher HSP70 expression during the day. In a forward genetic screen, we identified a key role for the chloroplast in controlling this response, suggesting that light-induced chloroplast signaling plays a key role. Consistent with this, we are able to globally activate binding of HSFA1a to its targets by altering redox status in planta independently of a heat shock. PMID- 29444422 TI - Netrin-1 Confines Rhombic Lip-Derived Neurons to the CNS. AB - During brainstem development, newborn neurons originating from the rhombic lip embark on exceptionally long migrations to generate nuclei important for audition, movement, and respiration. Along the way, this highly motile population passes several cranial nerves yet remains confined to the CNS. We found that Ntn1 accumulates beneath the pial surface separating the CNS from the PNS, with gaps at nerve entry sites. In mice null for Ntn1 or its receptor DCC, hindbrain neurons enter cranial nerves and migrate into the periphery. CNS neurons also escape when Ntn1 is selectively lost from the sub-pial region (SPR), and conversely, expression of Ntn1 throughout the mutant hindbrain can prevent their departure. These findings identify a permissive role for Ntn1 in maintaining the CNS-PNS boundary. We propose that Ntn1 confines rhombic lip-derived neurons by providing a preferred substrate for tangentially migrating neurons in the SPR, preventing their entry into nerve roots. PMID- 29444423 TI - Nuclear Organization in the Spinal Cord Depends on Motor Neuron Lamination Orchestrated by Catenin and Afadin Function. AB - Motor neurons in the spinal cord are found grouped in nuclear structures termed pools, whose position is precisely orchestrated during development. Despite the emerging role of pool organization in the assembly of spinal circuits, little is known about the morphogenetic programs underlying the patterning of motor neuron subtypes. We applied three-dimensional analysis of motor neuron position to reveal the roles and contributions of cell adhesive function by inactivating N cadherin, catenin, and afadin signaling. Our findings reveal that nuclear organization of motor neurons is dependent on inside-out positioning, orchestrated by N-cadherin, catenin, and afadin activities, controlling cell body layering on the medio-lateral axis. In addition to this lamination-like program, motor neurons undergo a secondary, independent phase of organization. This process results in segregation of motor neurons along the dorso-ventral axis of the spinal cord, does not require N-cadherin or afadin activity, and can proceed even when medio-lateral positioning is perturbed. PMID- 29444424 TI - Activity Regulates Cell Death within Cortical Interneurons through a Calcineurin Dependent Mechanism. AB - We demonstrate that cortical interneurons derived from ventral eminences, including the caudal ganglionic eminence, undergo programmed cell death. Moreover, with the exception of VIP interneurons, this occurs in a manner that is activity-dependent. In addition, we demonstrate that, within interneurons, Calcineurin, a calcium-dependent protein phosphatase, plays a critical role in sequentially linking activity to maturation (E15-P5) and survival (P5-P20). Specifically, embryonic inactivation of Calcineurin results in a failure of interneurons to morphologically mature and prevents them from undergoing apoptosis. By contrast, early postnatal inactivation of Calcineurin increases apoptosis. We conclude that Calcineurin serves a dual role of promoting first the differentiation of interneurons and, subsequently, their survival. PMID- 29444425 TI - Modulation of Apoptosis Controls Inhibitory Interneuron Number in the Cortex. AB - Cortical networks are composed of excitatory projection neurons and inhibitory interneurons. Finding the right balance between the two is important for controlling overall cortical excitation and network dynamics. However, it is unclear how the correct number of cortical interneurons (CIs) is established in the mammalian forebrain. CIs are generated in excess from basal forebrain progenitors, and their final numbers are adjusted via an intrinsically determined program of apoptosis that takes place during an early postnatal window. Here, we provide evidence that the extent of CI apoptosis during this critical period is plastic and cell-type specific and can be reduced in a cell-autonomous manner by acute increases in neuronal activity. We propose that the physiological state of the emerging neural network controls the activity levels of local CIs to modulate their numbers in a homeostatic manner. PMID- 29444426 TI - Inferior Olive HCN1 Channels Coordinate Synaptic Integration and Complex Spike Timing. AB - Cerebellar climbing-fiber-mediated complex spikes originate from neurons in the inferior olive (IO), are critical for motor coordination, and are central to theories of cerebellar learning. Hyperpolarization-activated cyclic-nucleotide gated (HCN) channels expressed by IO neurons have been considered as pacemaker currents important for oscillatory and resonant dynamics. Here, we demonstrate that in vitro, network actions of HCN1 channels enable bidirectional glutamatergic synaptic responses, while local actions of HCN1 channels determine the timing and waveform of synaptically driven action potentials. These roles are distinct from, and may complement, proposed pacemaker functions of HCN channels. We find that in behaving animals HCN1 channels reduce variability in the timing of cerebellar complex spikes, which serve as a readout of IO spiking. Our results suggest that spatially distributed actions of HCN1 channels enable the IO to implement network-wide rules for synaptic integration that modulate the timing of cerebellar climbing fiber signals. PMID- 29444427 TI - An Excitatory Neural Assembly Encodes Short-Term Memory in the Prefrontal Cortex. AB - Short-term memory (STM) is crucial for animals to hold information for a small period of time. Persistent or recurrent neural activity, together with neural oscillations, is known to encode the STM at the cellular level. However, the coding mechanisms at the microcircuitry level remain a mystery. Here, we performed two-photon imaging on behaving mice to monitor the activity of neuronal microcircuitry. We discovered a neuronal subpopulation in the medial prefrontal cortex (mPFC) that exhibited emergent properties in a context-dependent manner underlying a STM-like behavior paradigm. These neuronal subpopulations exclusively comprise excitatory neurons and mainly represent a group of neurons with stronger functional connections. Microcircuitry plasticity was maintained for minutes and was absent in an animal model of Alzheimer's disease (AD). Thus, these results point to a functional coding mechanism that relies on the emergent behavior of a functionally defined neuronal assembly to encode STM. PMID- 29444428 TI - AgRP Neurons Require Carnitine Acetyltransferase to Regulate Metabolic Flexibility and Peripheral Nutrient Partitioning. AB - AgRP neurons control peripheral substrate utilization and nutrient partitioning during conditions of energy deficit and nutrient replenishment, although the molecular mechanism is unknown. We examined whether carnitine acetyltransferase (Crat) in AgRP neurons affects peripheral nutrient partitioning. Crat deletion in AgRP neurons reduced food intake and feeding behavior and increased glycerol supply to the liver during fasting, as a gluconeogenic substrate, which was mediated by changes to sympathetic output and peripheral fatty acid metabolism in the liver. Crat deletion in AgRP neurons increased peripheral fatty acid substrate utilization and attenuated the switch to glucose utilization after refeeding, indicating altered nutrient partitioning. Proteomic analysis in AgRP neurons shows that Crat regulates protein acetylation and metabolic processing. Collectively, our studies highlight that AgRP neurons require Crat to provide the metabolic flexibility to optimize nutrient partitioning and regulate peripheral substrate utilization, particularly during fasting and refeeding. PMID- 29444430 TI - beta Cell-Specific Deletion of the IL-1 Receptor Antagonist Impairs beta Cell Proliferation and Insulin Secretion. AB - Interleukin-1 receptor antagonist (IL-1Ra) is elevated in the circulation during obesity and type 2 diabetes (T2D) but is decreased in islets from patients with T2D. The protective role of local IL-1Ra was investigated in pancreatic islet beta cell (betaIL-1Ra)-specific versus myeloid-cell (myeloIL-1Ra)-specific IL-1Ra knockout (KO) mice. Deletion of IL-1Ra in beta cells, but not in myeloid cells, resulted in diminished islet IL-1Ra expression. Myeloid cells were not the main source of circulating IL-1Ra in obesity. betaIL-1Ra KO mice had impaired insulin secretion, reduced beta cell proliferation, and decreased expression of islet proliferation genes, along with impaired glucose tolerance. The key cell-cycle regulator E2F1 partly reversed IL-1beta-mediated inhibition of potassium channel Kir6.2 expression and rescued impaired insulin secretion in IL-1Ra knockout islets. Our findings provide evidence for the importance of beta cell-derived IL 1Ra for the local defense of beta cells to maintain normal function and proliferation. PMID- 29444429 TI - Glucagon Receptor Antagonism Improves Glucose Metabolism and Cardiac Function by Promoting AMP-Mediated Protein Kinase in Diabetic Mice. AB - The antidiabetic potential of glucagon receptor antagonism presents an opportunity for use in an insulin-centric clinical environment. To investigate the metabolic effects of glucagon receptor antagonism in type 2 diabetes, we treated Leprdb/db and Lepob/ob mice with REMD 2.59, a human monoclonal antibody and competitive antagonist of the glucagon receptor. As expected, REMD 2.59 suppresses hepatic glucose production and improves glycemia. Surprisingly, it also enhances insulin action in both liver and skeletal muscle, coinciding with an increase in AMP-activated protein kinase (AMPK)-mediated lipid oxidation. Furthermore, weekly REMD 2.59 treatment over a period of months protects against diabetic cardiomyopathy. These functional improvements are not derived simply from correcting the systemic milieu; nondiabetic mice with cardiac-specific overexpression of lipoprotein lipase also show improvements in contractile function after REMD 2.59 treatment. These observations suggest that hyperglucagonemia enables lipotoxic conditions, allowing the development of insulin resistance and cardiac dysfunction during disease progression. PMID- 29444431 TI - Mechanisms to Evade the Phagocyte Respiratory Burst Arose by Convergent Evolution in Typhoidal Salmonella Serovars. AB - Typhoid fever caused by Salmonella enterica serovar (S.) Typhi differs in its clinical presentation from gastroenteritis caused by S. Typhimurium and other non typhoidal Salmonella serovars. The different clinical presentations are attributed in part to the virulence-associated capsular polysaccharide (Vi antigen) of S. Typhi, which prevents phagocytes from triggering a respiratory burst by preventing antibody-mediated complement activation. Paradoxically, the Vi antigen is absent from S. Paratyphi A, which causes a disease that is indistinguishable from typhoid fever. Here, we show that evasion of the phagocyte respiratory burst by S. Paratyphi A required very long O antigen chains containing the O2 antigen to inhibit antibody binding. We conclude that the ability to avoid the phagocyte respiratory burst is a property distinguishing typhoidal from non-typhoidal Salmonella serovars that was acquired by S. Typhi and S. Paratyphi A independently through convergent evolution. PMID- 29444432 TI - Surface-Matrix Screening Identifies Semi-specific Interactions that Improve Potency of a Near Pan-reactive HIV-1-Neutralizing Antibody. AB - Highly effective HIV-1-neutralizing antibodies could have utility in the prevention or treatment of HIV-1 infection. To improve the potency of 10E8, an antibody capable of near pan-HIV-1 neutralization, we engineered 10E8-surface mutants and screened for improved neutralization. Variants with the largest functional enhancements involved the addition of hydrophobic or positively charged residues, which were positioned to interact with viral membrane lipids or viral glycan-sialic acids, respectively. In both cases, the site of improvement was spatially separated from the region of antibody mediating molecular contact with the protein component of the antigen, thereby improving peripheral semi specific interactions while maintaining unmodified dominant contacts responsible for broad recognition. The optimized 10E8 antibody, with mutations to phenylalanine and arginine, retained the extraordinary breadth of 10E8 but with ~10-fold increased potency. We propose surface-matrix screening as a general method to improve antibodies, with improved semi-specific interactions between antibody and antigen enabling increased potency without compromising breadth. PMID- 29444433 TI - MicroRNA-223 Suppresses the Canonical NF-kappaB Pathway in Basal Keratinocytes to Dampen Neutrophilic Inflammation. AB - MicroRNA-223 is known as a myeloid-enriched anti-inflammatory microRNA that is dysregulated in numerous inflammatory conditions. Here, we report that neutrophilic inflammation (wound response) is augmented in miR-223-deficient zebrafish, due primarily to elevated activation of the canonical nuclear factor kappaB (NF-kappaB) pathway. NF-kappaB over-activation is restricted to the basal layer of the surface epithelium, although miR-223 is detected throughout the epithelium and in phagocytes. Not only phagocytes but also epithelial cells are involved in miR-223-mediated regulation of neutrophils' wound response and NF kappaB activation. Cul1a/b, Traf6, and Tab1 are identified as direct targets of miR-223, and their levels rise in injured epithelium lacking miR-223. In addition, miR-223 is expressed in cultured human bronchial epithelial cells, where it also downregulates NF-kappaB signaling. Together, this direct connection between miR-223 and the canonical NF-kappaB pathway provides a mechanistic understanding of the multifaceted role of miR-223 and highlights the relevance of epithelial cells in dampening neutrophil activation. PMID- 29444434 TI - B1 Cell IgE Impedes Mast Cell-Mediated Enhancement of Parasite Expulsion through B2 IgE Blockade. AB - Helminth infection is known for generating large amounts of poly-specific IgE. Here we demonstrate that innate-like B1 cells are responsible for this IgE production during infection with the nematode parasites Nippostrongylus brasiliensis and Heligmosomoides polygyrus bakeri. In vitro analysis of B1 cell immunoglobulin class switch recombination to IgE demonstrated a requirement for anti-CD40 and IL-4 that was further enhanced when IL-5 was added or when the B1 source was helminth infected mice. An IL-25-induced upregulation of IgE in B1 cells was also demonstrated. In T cell-reconstituted RAG1-/- mice, N. brasiliensis clearance was enhanced with the addition of B2 cells in an IgE dependent manner. This enhanced clearance was impeded by reconstitution with IgE sufficient B1 cells. Mucosal mast cells mediated the B2 cell enhancement of clearance in the absence of B1 cells. The data support B1 cell IgE secretion as a regulatory response exploited by the helminth. PMID- 29444435 TI - PTPN2 Regulates Inflammasome Activation and Controls Onset of Intestinal Inflammation and Colon Cancer. AB - Variants in the gene locus encoding protein tyrosine phosphatase non-receptor type 2 (PTPN2) are associated with inflammatory disorders, including inflammatory bowel diseases, rheumatoid arthritis, and type 1 diabetes. The anti-inflammatory role of PTPN2 is highlighted by the fact that PTPN2-deficient mice die a few weeks after birth because of systemic inflammation and severe colitis. However, the tissues, cells, and molecular mechanisms that contribute to this phenotype remain unclear. Here, we demonstrate that myeloid cell-specific deletion of PTPN2 in mice (PTPN2-LysMCre) promotes intestinal inflammation but protects from colitis-associated tumor formation in an IL-1beta-dependent manner. Elevated levels of mature IL-1beta production in PTPN2-LysMCre mice are a consequence of increased inflammasome assembly due to elevated phosphorylation of the inflammasome adaptor molecule ASC. Thus, we have identified a dual role for myeloid PTPN2 in directly regulating inflammasome activation and IL-1beta production to suppress pro-inflammatory responses during colitis but promote intestinal tumor development. PMID- 29444437 TI - Mutations in Cytosine-5 tRNA Methyltransferases Impact Mobile Element Expression and Genome Stability at Specific DNA Repeats. AB - The maintenance of eukaryotic genome stability is ensured by the interplay of transcriptional as well as post-transcriptional mechanisms that control recombination of repeat regions and the expression and mobility of transposable elements. We report here that mutations in two (cytosine-5) RNA methyltransferases, Dnmt2 and NSun2, impact the accumulation of mobile element derived sequences and DNA repeat integrity in Drosophila. Loss of Dnmt2 function caused moderate effects under standard conditions, while heat shock exacerbated these effects. In contrast, NSun2 function affected mobile element expression and genome integrity in a heat shock-independent fashion. Reduced tRNA stability in both RCMT mutants indicated that tRNA-dependent processes affected mobile element expression and DNA repeat stability. Importantly, further experiments indicated that complex formation with RNA could also contribute to the impact of RCMT function on gene expression control. These results thus uncover a link between tRNA modification enzymes, the expression of repeat DNA, and genomic integrity. PMID- 29444436 TI - Shwachman-Diamond Syndrome Protein SBDS Maintains Human Telomeres by Regulating Telomerase Recruitment. AB - Shwachman-Diamond syndrome (SDS) is a rare pediatric disease characterized by various systemic disorders, including hematopoietic dysfunction. The mutation of Shwachman-Bodian-Diamond syndrome (SBDS) gene has been proposed to be a major causative reason for SDS. Although SBDS patients were reported to have shorter telomere length in granulocytes, the underlying mechanism is still unclear. Here we provide data to elucidate the role of SBDS in telomere protection. We demonstrate that SBDS deficiency leads to telomere shortening. We found that overexpression of disease-associated SBDS mutants or knockdown of SBDS hampered the recruitment of telomerase onto telomeres, while the overall reverse transcriptase activity of telomerase remained unaffected. Moreover, we show that SBDS could specifically bind to TPP1 during the S phase of cell cycle, likely functioning as a stabilizer for TPP1-telomerase interaction. Our findings suggest that SBDS is a telomere-protecting protein that participates in regulating telomerase recruitment. PMID- 29444438 TI - Commonly Occurring Cell Subsets in High-Grade Serous Ovarian Tumors Identified by Single-Cell Mass Cytometry. AB - We have performed an in-depth single-cell phenotypic characterization of high grade serous ovarian cancer (HGSOC) by multiparametric mass cytometry (CyTOF). Using a CyTOF antibody panel to interrogate features of HGSOC biology, combined with unsupervised computational analysis, we identified noteworthy cell types co occurring across the tumors. In addition to a dominant cell subset, each tumor harbored rarer cell phenotypes. One such group co-expressed E-cadherin and vimentin (EV), suggesting their potential role in epithelial mesenchymal transition, which was substantiated by pairwise correlation analyses. Furthermore, tumors from patients with poorer outcome had an increased frequency of another rare cell type that co-expressed vimentin, HE4, and cMyc. These poorer outcome tumors also populated more cell phenotypes, as quantified by Simpson's diversity index. Thus, despite the recognized genomic complexity of the disease, the specific cell phenotypes uncovered here offer a focus for therapeutic intervention and disease monitoring. PMID- 29444439 TI - Differential Effector Engagement by Oncogenic KRAS. AB - KRAS can bind numerous effector proteins, which activate different downstream signaling events. The best known are RAF, phosphatidylinositide (PI)-3' kinase, and RalGDS families, but many additional direct and indirect effectors have been reported. We have assessed how these effectors contribute to several major phenotypes in a quantitative way, using an arrayed combinatorial siRNA screen in which we knocked down 41 KRAS effectors nodes in 92 cell lines. We show that every cell line has a unique combination of effector dependencies, but in spite of this heterogeneity, we were able to identify two major subtypes of KRAS mutant cancers of the lung, pancreas, and large intestine, which reflect different KRAS effector engagement and opportunities for therapeutic intervention. PMID- 29444440 TI - Measuring Integrin Conformational Change on the Cell Surface with Super Resolution Microscopy. AB - We use super-resolution interferometric photoactivation and localization microscopy (iPALM) and a constrained photoactivatable fluorescent protein integrin fusion to measure the displacement of the head of integrin lymphocyte function-associated 1 (LFA-1) resulting from integrin conformational change on the cell surface. We demonstrate that the distance of the LFA-1 head increases substantially between basal and ligand-engaged conformations, which can only be explained at the molecular level by integrin extension. We further demonstrate that one class of integrin antagonist maintains the bent conformation, while another antagonist class induces extension. Our molecular scale measurements on cell-surface LFA-1 are in excellent agreement with distances derived from crystallographic and electron microscopy structures of bent and extended integrins. Our distance measurements are also in excellent agreement with a previous model of LFA-1 bound to ICAM-1 derived from the orientation of LFA-1 on the cell surface measured using fluorescence polarization microscopy. PMID- 29444441 TI - Initiating Events in Direct Cardiomyocyte Reprogramming. AB - Direct reprogramming of fibroblasts into cardiomyocyte-like cells (iCM) holds great potential for heart regeneration and disease modeling and may lead to future therapeutic applications. Currently, application of this technology is limited by our lack of understanding of the molecular mechanisms that drive direct iCM reprogramming. Using a quantitative mass spectrometry-based proteomic approach, we identified the temporal global changes in protein abundance that occur during initial phases of iCM reprogramming. Collectively, our results show systematic and temporally distinct alterations in levels of specific functional classes of proteins during the initiating steps of reprogramming including extracellular matrix proteins, translation factors, and chromatin-binding proteins. We have constructed protein relational networks associated with the initial transition of a fibroblast into an iCM. These findings demonstrate the presence of an orchestrated series of temporal steps associated with dynamic changes in protein abundance in a defined group of protein pathways during the initiating events of direct reprogramming. PMID- 29444443 TI - Kinetics and Mechanism of Mammalian Mitochondrial Ribosome Assembly. AB - Mammalian mtDNA encodes only 13 proteins, all essential components of respiratory complexes, synthesized by mitochondrial ribosomes. Mitoribosomes contain greatly truncated RNAs transcribed from mtDNA, including a structural tRNA in place of 5S RNA as a scaffold for binding 82 nucleus-encoded proteins, mitoribosomal proteins (MRPs). Cryoelectron microscopy (cryo-EM) studies have determined the structure of the mitoribosome, but its mechanism of assembly is unknown. Our SILAC pulse labeling experiments determine the rates of mitochondrial import of MRPs and their assembly into intact mitoribosomes, providing a basis for distinguishing MRPs that bind at early and late stages in mitoribosome assembly to generate a working model for mitoribosome assembly. Mitoribosome assembly is a slow process initiated at the mtDNA nucleoid driven by excess synthesis of individual MRPs. MRPs that are tightly associated in the structure frequently join the complex in a coordinated manner. Clinically significant MRP mutations reported to date affect proteins that bind early on during assembly. PMID- 29444442 TI - Diverse Regulators of Human Ribosome Biogenesis Discovered by Changes in Nucleolar Number. AB - Ribosome biogenesis is a highly regulated, essential cellular process. Although studies in yeast have established some of the biological principles of ribosome biogenesis, many of the intricacies of its regulation in higher eukaryotes remain unknown. To understand how ribosome biogenesis is globally integrated in human cells, we conducted a genome-wide siRNA screen for regulators of nucleolar number. We found 139 proteins whose depletion changed the number of nucleoli per nucleus from 2-3 to only 1 in human MCF10A cells. Follow-up analyses on 20 hits found many (90%) to be essential for the nucleolar functions of rDNA transcription (7), pre-ribosomal RNA (pre-rRNA) processing (16), and/or global protein synthesis (14). This genome-wide analysis exploits the relationship between nucleolar number and function to discover diverse cellular pathways that regulate the making of ribosomes and paves the way for further exploration of the links between ribosome biogenesis and human disease. PMID- 29444444 TI - Vertical disconjugacy during reading in dyslexic and non-dyslexic children. AB - PURPOSE: The objective of this study was to explore vertical binocular coordination in dyslexic and non-dyslexic children during saccades and post saccadic fixation period while reading a text. METHODS: Binocular eye movements were recorded by an infrared system (Mobile T2(r), SuriCog) in thirty-six dyslexic children from 7.3 to 13.6 years of age (mean age: 10.4 +/- 0.3 years) who were asked to silently read a four-line text during binocular viewing. Data were compared to those of thirty-six age-matched non-dyslexic children. RESULTS: Vertical disconjugacy during post-saccadic fixation was higher in dyslexic children with respect to non-dyslexic children group. Vertical disconjugacy was not age-dependent either for dyslexic children or for non-dyslexic children. CONCLUSIONS: The poor binocular vertical coordination observed in dyslexic children while reading could suggest a deficiency in the cerebellum and/or extra ocular muscles involved in vertical eye alignment. Moreover, the fact that this vertical binocular coordination was not age-dependent could be due to an abnormal eye position and/or to a dysfunction of midbrain structures involved in vertical vergences. PMID- 29444445 TI - Individual differences in the processing of referential dependencies: Evidence from event-related potentials. AB - The present study examines the processing of referential ambiguity and referential failure using event-related potentials (ERPs). Participants read sentences with pronouns (he, she) which contained either one, two, or no potential gender-matching antecedents. Participants also took tests of working memory (Count Span/Reading Span) and attentional control (Number Stroop). In contexts of referential ambiguity with two potential gender-matching antecedents, two different responder types emerged, with some participants yielding a sustained negativity (Nref) and others a sustained positivity. For individuals who elicited Nref, the size of the effect was related to working memory such that higher Count Span scores were related to a larger Nref. For individuals who elicited a positivity, the effect was marginally related to attentional control such that better performance on the Stroop was related to a less positive, or increasingly negative-going ERP effect. Contexts of referential failure, with no gender-matching antecedents, yielded P600 for all participants, suggesting that participants may treat the failure of the pronoun to agree in gender with the antecedents as a violation despite the absence of an explicit acceptability judgment task. PMID- 29444446 TI - Pathophysiological changes after lipopolysaccharide-induced acute inflammation in a type 2 diabetic rat model versus normal controls. AB - AIMS: The present study aimed to explore the mechanism of a potential beneficial effect of pre-existing diabetes in acute hyperglycemia during critical illness. METHODS: Pathophysiological changes including blood glucose variability, changes of inflammatory and oxidative stress responses after lipopolysaccharide (LPS) induced acute infection were compared between type 2 diabetic rat model (GK rats) and normal controls (Wistar rats). RESULTS: After LPS injection, Wistar rats showed serious infective symptoms while GK rats did not. Blood glucose (BG) levels were significantly elevated in both GK and Wistar rats; however, compared to Wistar rats, GK rats had lower BG variability, smaller increases in the serum tumor necrosis factor (TNF)-alpha and interleukin (IL)-6 levels, a larger increase in the serum IL-10 level, and a smaller decrease in the IkappaB-alpha protein level of lung tissue. Serum malondialdehyde (MDA) levels increased and serum total antioxidant capacity (T-AOC) levels decreased for both GK and Wistar rats. CONCLUSIONS: We found diabetes was associated with adaptive changes at the cellular level that might actually be protective in acute hyperglycemia-mediated damage during sepsis. Chronic exposure to hyperglycemia potentially reduced the acute deleterious effects of acute hyperglycemia on septic mortality by decreasing BG variability, blunting the pro-inflammatory response and elevating the anti-inflammatory response. PMID- 29444448 TI - Tracking small sensory nerve action potentials in human axonal excitability studies. AB - BACKGROUND: Excitability studies on normal and diseased human axons in vivo have been greatly enhanced by fast non-invasive threshold-tracking techniques, using surface stimulation and recording. Although sensory axons are often more affected in disease, most studies to date have focussed on motor axons, because of technical difficulties in resolving pathologically small nerve volleys in the presence of noise and stimulus artefact. NEW METHODS: This paper describes techniques for tracking low-amplitude compound action potentials, using a battery powered, isolated preamplifier of simple construction with high common mode rejection (>125 dB [balanced inputs]) and low noise (<0.4 MUV referred to inputs [shorted]). RESULTS: We demonstrate the preamplifier's capability by tracking targets as small as 2 MUV for a full range of excitability measurements without the usual distortion due to residual stimulus artefact and without the need for clamping, additional filtering or ensemble averaging. COMPARISON WITH EXISTING METHODS: In practice, threshold-tracking studies have been unable to study sensory axons when the maximal compound sensory action potential was less than about 15 MUV. The techniques and amplifier in the present study allow measurements to be made from nerve with maximal responses less than half that size, and we present three recordings in patients with pathologically small nerve action potentials <=7 MUV. CONCLUSIONS: Based on measurements of stimulus artefact distortion, noise and the performance in experiments, we conclude that the techniques described here will facilitate the study of diseased axons for which the sensory potentials have high thresholds and may be only a few microvolts in amplitude.

AB - AIM: We aimed to investigate the association of difference between observed and predicted glycated hemoglobin (dopHbA1c) and HbA1c reduction after vildagliptin based oral therapy in patients with type 2 diabetes (T2D). METHODS: This was a prospective observational study. Adults >= 20 years old with T2D and HbA1c ?7% treated with oral anti-diabetic drugs (OADs) were eligible if their OADs were shifted to vildagliptin-based dual oral therapy. Fasting plasma glucose (FPG) and HbA1c were recorded at baseline, week 12, and week 24. To determine baseline dopHbA1c, a predicted HbA1c was calculated by inserting baseline FPG into a regression equation (HbA1c = FPG * 0.0225 + 4.3806) developed from linear relationship between HbA1c and FPG in an independent cohort of 3239 outpatients with T2D (dopHbA1c = observed HbA1c - predicted HbA1c). Patients were assigned to low (?0) or high (>0) dopHbA1c group according to their baseline dopHbA1c levels. The study endpoint was changes from baseline to week 24 in HbA1c levels. RESULTS: A total of 1224 patients were enrolled. Patients with a dopHbA1c >0 had a greater HbA1c reduction after vildagliptin-based dual oral therapy than those with a dopHbA1c ?0 (-1.5 +/- 2.0 vs. -0.4 +/- 1.0%, p < 0.001). Baseline dopHbA1c was positively associated with HbA1c reduction from baseline to week 24 (beta coefficient 0.883, 95% CI 0.811 to 0.955, p < 0.001), and the association remained significant after adjustment for confounders. CONCLUSIONS: In T2D patients with an HbA1c ?7%, a higher baseline dopHbA1c was associated with a greater HbA1c reduction after shifting to vildagliptin-based dual oral therapy. PMID- 29444449 TI - Dendritic spine density and EphrinB2 levels of hippocampal and anterior cingulate cortex neurons increase sequentially during formation of recent and remote fear memory in the mouse. AB - Memory consolidation is a dynamic process that involves a sequential remodeling of hippocampal-cortical circuits. Although synaptic events underlying memory consolidation are well assessed, fine molecular events controlling this process deserve further characterization. To this aim, we challenged male C57BL/6N mice in a contextual fear conditioning (CFC) paradigm and tested their memory 24 h, 7 days or 36 days later. Mice displayed a strong fear response at all time points with an increase in dendritic spine density and protein levels of the cell adhesion factor EphrinB2 in CA1 hippocampal neurons 24 h and 7 days post conditioning (p.c.), and in anterior cingulate cortex (ACC) neurons 36 days p.c. We then investigated whether the formation of remote memory and neuronal modifications in the ACC would depend on p.c. protein synthesis in hippocampal neurons. Bilateral intrahippocampal infusions with the protein synthesis inhibitor anisomycin administered immediately p.c. decreased fear response, neuronal spine growth and EphrinB2 protein levels of hippocampal and ACC neurons 24 h and 36 days p.c., respectively. Anisomycin infusion 24 h p.c. had no effects on fear response, increase in spine density and in EphrinB2 protein levels in ACC neurons 36 days p.c. Our results thus confirm that early but not late p.c. hippocampal protein synthesis is necessary for the formation of remote memory and provide the first evidence of a possible involvement of EphrinB2 in neuronal plasticity in the ACC. PMID- 29444451 TI - Risk factors for neonatal death in the capital city with the lowest infant mortality rate in Brazil. AB - OBJECTIVES: To analyze the risk factors for neonatal death in Florianopolis, the Brazilian city capital with the lowest infant mortality rate. METHOD: Data were extracted from a historical cohort with 15,879 live births. A model was used that included socioeconomic, behavioral, and health service use risk factors, as well as the Apgar score and biological factors. Risk factors were analyzed by hierarchical logistic regression. RESULTS: Based on the multivariate analysis, socioeconomic factors showed no association with death. Insufficient prenatal consultations showed an OR of 3.25 (95% CI: 1.70-6.48) for death. Low birth weight (OR 8.42; 95% CI: 3.45-21.93); prematurity (OR 5.40; 95% CI: 2.22-13.88); malformations (OR 4.42; 95% CI: 1.37-12.43); and low Apgar score at the first (OR 6.65; 95% CI: 3.36-12.94) and at the fifth (OR 19.78; 95% CI: 9.12-44.50) minutes, were associated with death. CONCLUSION: Differing from other studies, socioeconomic conditions were not associated with neonatal death. Insufficient prenatal consultations, low Apgar score, prematurity, low birth weight, and malformations showed an association, reinforcing the importance of prenatal access universalization and its integration with medium and high-complexity neonatal care services. PMID- 29444450 TI - High-throughput screening identifies small molecules that bind to the RAS:SOS:RAS complex and perturb RAS signaling. AB - K-RAS is mutated in approximately 30% of human cancers, resulting in increased RAS signaling and tumor growth. Thus, RAS is a highly validated therapeutic target, especially in tumors of the pancreas, lung and colon. Although directly targeting RAS has proven to be challenging, it may be possible to target other proteins involved in RAS signaling, such as the guanine nucleotide exchange factor Son of Sevenless (SOS). We have previously reported on the discovery of small molecules that bind to SOS1, activate SOS-mediated nucleotide exchange on RAS, and paradoxically inhibit ERK phosphorylation (Burns et al., PNAS, 2014). Here, we describe the discovery of additional, structurally diverse small molecules that also bind to SOS1 in the same pocket and elicit similar biological effects. We tested >160,000 compounds in a fluorescence-based assay to assess their effects on SOS-mediated nucleotide exchange. X-Ray structures revealed that these small molecules bind to the CDC25 domain of SOS1. Compounds that elicited high levels of nucleotide exchange activity in vitro increased RAS-GTP levels in cells, and inhibited phospho ERK levels at higher treatment concentrations. The identification of structurally diverse SOS1 binding ligands may assist in the discovery of new molecules designed to target RAS-driven tumors. PMID- 29444452 TI - Insulation fiber deposition in the airways of men and rats. A review of experimental and computational studies. AB - The typical insulation rock, slag and glass wool fibers are high volume materials. Current exposure levels in industry (generally <= 1 fiber/cm3 with a median diameter ~1 MUm and length >=10 MUm) are not considered carcinogenic or causing other types of severe lung effects. However, epidemiological studies are not informative on effects in humans at fiber levels >1 fiber/cm3. Effects may be inferred from valid rat studies, conducted with rat respirable fibers (diameter <= 1.5 MUm). Therefore, we estimate delivery and deposition in human and rat airways of the industrial fibers. The deposition fractions in humans head regions by nasal (~0.20) and by mouth breathing (<=0.08) are lower than in rats (0.50). The delivered dose into the lungs per unit lung surface area during a 1-day exposure at a similar air concentration is estimated to be about two times higher in humans than in rats. The deposition fractions in human lungs by nasal (~0.20) and by mouth breathing (~0.40) are higher than in rats (~0.04). The human lung deposition may be up to three times by nasal breathing and up to six times higher by oral breathing than in rats, qualifying assessment factor setting for deposition. PMID- 29444453 TI - Efferocytosis in atherosclerotic lesions: Malfunctioning regulatory pathways and control mechanisms. AB - Atherosclerosis is a dynamic and progressive inflammatory process in the intimal layer of large and medium-sized arteries, and it is the major contributor to the atherosclerotic cardiovascular disease (ACVD), the leading cause of death worldwide. In an atherosclerotic plaque, phagocytosis of apoptotic cells occurs through an intricate process designated efferocytosis. Defective efferocytosis has emerged as a causal factor in the etiopathogenesis of atherosclerosis and its progression into overt ACVD. Both specialized phagocytes (macrophages and dendritic cells) and non-specialized cells with phagocytic capabilities (smooth muscle and endothelial cells) are involved in the efferocytotic process. Moreover, several signaling and regulatory molecules are involved in the different steps of efferocytosis, and they include "Find-Me" signals (lysophosphatidylcholine), "Eat-Me" signals [phosphatidylserine, Mer tyrosine kinase (MerTK), and milk fat globule-EGF factor 8], and "Don't Eat-Me" signals [cluster of differentiation 47 (CD47)]. Regulation of efferocytosis is in a close nexus with inflammation, the key component in atherosclerosis. The predominance of pro-inflammatory and anti-inflammatory molecules plays a crucial role in lesion progression and regression, respectively. Polarization of macrophages towards the M1 phenotype causes them to secrete proinflammatory cytokines, while polarization towards the M2 phenotype causes them to secrete of anti-inflammatory cytokines, including interleukin-10 and transforming growth factor beta, so tending to shift the balance towards resolution of the inflammation. Dysfunction of any regulatory signal may cause expansion of the necrotic core of an atherosclerotic plaque with ensuing conversion of the plaque into an unstable plaque with an increased susceptibility to rupture and to atherothrombotic complication. In this review we aim at elucidating the determinant factors and pathways of efferocytosis which can be considered as potential novel targets when striving to develop more personalized and efficient treatment regimens for patients with ACVD. PMID- 29444454 TI - Assessing the blocking of occasion setting. AB - An occasion setter (OS) is a stimulus or context with the capacity to disambiguate an ambiguous conditioned stimulus (CS). Previous research has shown that OSs share some features with regular Pavlovian CSs. Amongst them, research has shown that OSs are subject to blocking; that is, a new OS exerts reduced behavioral control after training in compound with a previously established OS. Of additional interest, in Pavlovian blocking, it has been reported that a blocked CS comes to elicit conditioned responding after the extinction of the blocking CS. This is an example of retrospective revaluation, a family of phenomena in which the response to a specific stimulus is modified by training a related cue. Here, three experiments sought to extend the analogies between OS and Pavlovian conditioning by examining the blocking of OSs and its retrospective revaluation. In all experiments, an OS was established by pairing a CS with food in the presence of the OS, but not in its absence (i.e., positive OS). Blocking was then trained by presenting the OS in compound with a novel OS. Experiment 1 showed blocking of the second OS, but direct exposure to the blocking OS did not enhance responding to the second OS. Experiment 2 replicated the blocking effect but subsequent training of the blocking OS with a reversed contingency showed no retrospective revaluation. Experiment 3 examined whether blocking of the OS occurred with a novel CS during the compound phase. In this experiment blocking was again observed, but only when subjects were tested with the original CS. These results are discussed focusing on the underlying links at work in occasion setting. PMID- 29444455 TI - The perceptions of anatomists in the US and Europe of the skills and attributes required of newly-recruited medical students. AB - BACKGROUND AND PURPOSE: Admission procedures for recruiting students to medical school vary considerably across the world. Notwithstanding such variability, it is important to know what skills and attributes (including attitudes and personality traits) are required of the students by their teachers on entering medical school. PROCEDURES: Anatomists are often the teachers who first meet the students as they enter medical school and this report analyses, by means of a paper-based questionnaire, the putative skills required of their medical students by anatomists from the U.S.A. and Europe. Questionnaires were distributed to 150 anatomists, of varying ages and teaching experience, with 108 responding with completed questionnaires (i.e. 72% returns). FINDINGS: The findings from a questionnaire suggest that there are few differences between anatomists in the U.S.A. and Europe, even though medical students are postgraduates in the U.S.A. but undergraduates in Europe. Furthermore, the skill requirements expected of the students differed only slightly according to the gender and age of the anatomists and to whether or not they had clinical qualifications. In order of perceived importance, the most important skills and attributes required of the students were found to be: good study skills, memory/factual retention, conscientiousness, emotional stability, understanding of biology (but not chemistry, physics, mathematics, statistics, or understanding of the scientific method), life-long learning skills, ability to study independently, problem-solving abilities, readiness to be challenged, communication skills, and teamwork skills. CONCLUSIONS: Anatomists within the U.S.A. and Europe essentially agree on the skills and attributes initially required of their medical students, as well as those not deemed initially important. These findings are presented with the view of enhancing admission policies and procedures for admitting students into medical schools. PMID- 29444456 TI - Gap junctional intercellular communication and endoplasmic reticulum stress regulate chronic cadmium exposure induced apoptosis in HK-2 cells. AB - Cadmium (Cd), a toxic heavy metal, is known to induce renal toxicity by primarily targeting at renal proximal tubule. Endoplasmic reticulum (ER) stress and gap junctional intercellular communication (GJIC) regulate many pathophysiological processes. Yet, how ER stress and GJIC regulate Cd-induced nephrotoxicity remain elusive. In this study, we treated human proximal tubule (HK-2) cells with 1 MUM CdCl2 every other day for 12 days and found that Cd significantly increased cell apoptosis at 10 and 12 days. This cytotoxicity correlated with activation of ER stress and apoptotic signaling evidenced by upregulation of inositol-requiring enzyme 1 (IRE1alpha), splice X-box binding protein-1 (XBP-1s), and apoptosis signal-regulating kinase 1 (ASK1) proteins. Interestingly, the AKT signaling was activated at 2- and 4-day and then inhibited at 10- and 12-day of Cd treatment; by contrast, Cd decreased GJIC levels at 2- and 4-day followed by a significant increase at 10- and 12-day treatment. Activation of AKT by SC79 or inhibition of GJIC by 18alpha-glycyrrhetinic acid (18alpha-GA) completely abolished Cd-induced AKT inhibition and IRE1alpha-ASK1 activation. Importantly, pretreatment with ER stress inhibitor or 18alpha-GA significantly mitigated Cd-induced apoptosis. These results suggest that GJIC collaborates with AKT signaling and ER stress in regulating prolonged Cd-treatment-induced apoptosis in HK-2 cells. PMID- 29444457 TI - Brain-region specific responses of astrocytes to an in vitro injury and neurotrophins. AB - Astrocytes are a heterogeneous population of glial cells that react to brain insults through a process referred to as astrogliosis. Reactive astrocytes are characterized by an increase in proliferation, size, migration to the injured zone and release of a plethora of chemical mediators such as NGF and BDNF. The aim of this study was to determine whether there are brain region-associated responses of astrocytes to an injury and to the neurotrophins NGF and BDNF. We used the scratch injury model to study the closure of a wound inflicted on a monolayer of astrocytes obtained from cortex, hippocampus or striatum. Our results indicate that the response of astrocytes to a mechanical lesion differ according to brain regions. Astrocytes from the striatum proliferate and repopulate the injury site more rapidly than astrocytes from cortex or hippocampus. We found that the scratch injury induced the upregulation of neurotrophin receptor p75NTR and TrkB.t in astrocytes from all brain regions studied. When astrocytes from all regions were treated with NGF, the neurotrophin induced migration of the astrocytes (assessed in Boyden chambers) and induced wound closure but did not affect proliferation. In contrast, BDNF induced wound closure but only in astrocytes from striatum. Our overall findings show the heterogeneity in astrocyte functions based on their brain region of origin, and how this functional diversity may determine their responses to an injury and to neurotrophins. PMID- 29444458 TI - Effect of glycated insulin on the blood-brain barrier permeability: An in vitro study. AB - Altered blood-brain barrier (BBB) permeability may contribute to pathogenesis of diabetes-related central nervous system disorders. Considering the presence of glycated insulin in plasma of type 2 diabetic patients, we hypothesized that glycated insulin could induce changes in paracellular permeability in BBB. Therefore, the authors decided to study the effect of glycated insulin on paracellular permeability in a BBB model and the change induced in insulin conformation upon glycation. In this study, the structural modification was examined by fluorescence and circular dichroism spectroscopies and dynamic light scattering. Cell proliferation and production of ROS in astrocytes and HUVEC cells were analyzed by MTT and spectrofluorometric assays, respectively. Apoptosis induction was determined and confirmed by flow cytometry and western blot analyses, respectively. The permeability was measured Lucifer yellow and FITC-Dextran. According to our results, glycated insulin presented altered conformation and more exposed hydrophobic patches than insulin. Formation of oligomeric species and advanced glycated end products (AGEs) were determined. Lower cell viability, higher apoptosis, and more ROS were detected upon treatment of cells with glycated insulin. Finally, glycated insulin led to increased Lucifer yellow and FITC-dextran transportation across the BBB model which could result from ROS producing and apoptosis-inducing activities of AGE-insulin. PMID- 29444459 TI - Cell adhesion and matricellular support by astrocytes of the tripartite synapse. AB - Astrocytes contribute to the formation, function, and plasticity of synapses. Their processes enwrap the neuronal components of the tripartite synapse, and due to this close interaction they are perfectly positioned to modulate neuronal communication. The interaction between astrocytes and synapses is facilitated by cell adhesion molecules and matricellular proteins, which have been implicated in the formation and functioning of tripartite synapses. The importance of such neuron-astrocyte integration at the synapse is underscored by the emerging role of astrocyte dysfunction in synaptic pathologies such as autism and schizophrenia. Here we review astrocyte-expressed cell adhesion molecules and matricellular molecules that play a role in integration of neurons and astrocytes within the tripartite synapse. PMID- 29444460 TI - Plasmacytoid pre-dendritic cells (pDC): from molecular pathways to function and disease association. AB - Plasmacytoid pre-dendritic cells (pDC) are a specialized DC population with a great potential to produce large amounts of type I interferon (IFN). pDC are involved in the initiation of antiviral immune responses through their interaction with innate and adaptive immune cell populations. In a context dependent manner, pDC activation can induce their differentiation into mature DC able to induce both T cell activation or tolerance. In this review, we described pDC functions during immune responses and their implication in the clearance or pathogenicity of human diseases during infection, autoimmunity, allergy and cancer. We discuss recent advances in the field of pDC biology and their implication for future studies. PMID- 29444461 TI - Homology threading to generate RNA polymerase structures. AB - Homology threading is a powerful technology for generating structural models based on homologous structures. Here we use threading to generate four complex RNA polymerase models. The models appear to be as useful as x-ray crystal structures or cryo-electron microscopy structures to support research projects. PMID- 29444462 TI - Photodynamic therapy as a new approach to Trichomonas vaginalis inactivation. AB - The emergence of nitroimidazole resistant isolates has been an aggravating factor in the treatment of trichomoniasis, the most common non-viral sexually transmitted disease in the world. This highlights the importance of new technologies that are safe, effective, and have minor side effects or resistance. Hence, we evaluated the effectiveness of photodynamic therapy on the inactivation of Trichomonas vaginalis in vitro. We used methylene blue as a photosensitizing substance, and a light-emitting diode (LED) for irradiation of metronidazole sensitive and resistant strains. Our results showed that only the presence of light did not interfere with parasite growth; however, methylene blue isolated or associated with light inhibited 31.78% +/- 7.18 and 80.21% +/- 7.11 of the sensitive strain, respectively, and 31.17% +/- 4.23 and 91.13% +/- 2.31 of the resistant strain, respectively. The high trichomonicidal activity of the photodynamic therapy, associated with low cost and ease of application, signalize its great therapeutic potential not only when conventional treatment fails, but also routinely in women with trichomoniasis. PMID- 29444463 TI - A comparative study on oxidative stress response in the hepatopancreas and midgut of the white shrimp Litopenaeus vannamei under gradual changes to low or high pH environment. AB - White shrimp Litopenaeus vannamei were reared under conditions of gradual changes to a low pH (gradual-low pH, 6.65-8.20) or a high pH (gradual-high pH, 8.20-9.81) versus a normal pH environment (8.14-8.31) during a 28-day period. Survival of shrimp, and ROS production, antioxidant responses and oxidative damage in the hepatopancreas and midgut were investigated. Consequently, shrimp enhanced MnSOD, GPx, and Hsp70 transcripts as early defense mechanism in the hepatopancreas and midgut to scavenge excessive ROS during short-term (<= 7 days) gradual-low and high pH stress. Meanwhile, the hepatopancreas was more sensitive to ROS than midgut because of earlier ROS production increase, antioxidant response and oxidative damage. Then, suppressed antioxidant response in the hepatopancreas and midgut of shrimp suggested a loss of antioxidant regulatory capacity caused by aggravated oxidative damage after long-term (>= 14 days) gradual-high pH stress, leading to continuous death. However, enhanced GPx, GST, and Hsp70 transcripts in the hepatopancreas and midgut might be long-term(>= 14 days) antioxidant adaptation mechanism of shrimp to gradual-low pH stress, which could prevent further ROS perturbation and weaken oxidative damage to achieve a new immune homeostasis, contributing to stable survival rate. Therefore, we have a few insights that it is necessary to protect hepatopancreas for controlling shrimp death under gradual-high pH stress. PMID- 29444464 TI - Transcriptional profiling, molecular cloning, and functional analysis of C1 inhibitor, the main regulator of the complement system in black rockfish, Sebastes schlegelii. AB - C1-inhibitor (C1inh) plays a crucial role in assuring homeostasis and is the central regulator of the complement activation involved in immunity and inflammation. A C1-inhibitor gene from Sebastes schlegelii was identified and designated as SsC1inh. The identified genomic DNA and cDNA sequences were 6837 bp and 2161 bp, respectively. The genomic DNA possessed 11 exons, interrupted by 10 introns. The amino acid sequence possessed two immunoglobulin-like domains and a serpin domain. Multiple sequence alignment revealed that the serpin domain of SsC1inh was highly conserved among analyzed species where the two immunoglobulin like domains showed divergence. The distinctiveness of teleost C1inh from other homologs was indicated by the phylogenetic analysis, genomic DNA organization, and their extended N-terminal amino acid sequences. Under normal physiological conditions, SsC1inh mRNA was most expressed in the liver, followed by the gills. The involvement of SsC1inh in homeostasis was demonstrated by modulated transcription profiles in the liver and spleen upon pathogenic stress by different immune stimulants. The protease inhibitory potential of recombinant SsC1inh (rSsC1inh) and the potentiation effect of heparin on rSsC1inh was demonstrated against C1esterase and thrombin. For the first time, the anti protease activity of the teleost C1inh against its natural substrates C1r and C1s was proved in this study. The protease assay conducted with recombinant black rockfish C1r and C1s proteins in the presence or absence of rSsC1inh showed that the activities of both proteases were significantly diminished by rSsC1inh. Taken together, results from the present study indicate that SsC1inh actively plays a significant role in maintaining homeostasis in the immune system of black rock fish. PMID- 29444465 TI - Simultaneous detection of human CYP2C19 polymorphisms and antibiotic resistance of Helicobacter pylori using a personalised diagnosis kit. AB - OBJECTIVES: A personalised diagnosis kit for Helicobacter pylori that employs visual gene chip technology for the simultaneous detection of CYP2C19 polymorphisms and clarithromycin/levofloxacin antibiotic resistance was evaluated. METHODS: Gastric antrum mucosa biopsy specimens of 394 patients were tested using the kit. DNA sequencing and antibiotic susceptibility testing of the H. pylori were also performed. RESULTS: In total, 267 (67.8%) of the 394 specimens were positive for H. pylori using the kit and DNA sequencing, and 136 (34.5%) were positive by culturing. For human CYP2C19 and the bacterial 23S rRNA and gyrA genes, the concordance rates were 92.4% (364/394), 96.6% (258/267) and 97.0% (259/267) between the kit and DNA sequencing results, respectively. For clarithromycin and levofloxacin resistance, the concordance rates were 90.4% (123/136) and 81.6% (111/136) between the kit and antibiotic susceptibility testing results. CONCLUSIONS: The personalised diagnosis kit for H. pylori provides useful information for the choice of proton pump inhibitor and antibiotic in combination therapy. PMID- 29444466 TI - Interference and problem size effect in multiplication fact solving: Individual differences in brain activations and arithmetic performance. AB - In the development of math ability, a large variability of performance in solving simple arithmetic problems is observed and has not found a compelling explanation yet. One robust effect in simple multiplication facts is the problem size effect, indicating better performance for small problems compared to large ones. Recently, behavioral studies brought to light another effect in multiplication facts, the interference effect. That is, high interfering problems (receiving more proactive interference from previously learned problems) are more difficult to retrieve than low interfering problems (in terms of physical feature overlap, namely the digits, De Visscher and Noel, 2014). At the behavioral level, the sensitivity to the interference effect is shown to explain individual differences in the performance of solving multiplications in children as well as in adults. The aim of the present study was to investigate the individual differences in multiplication ability in relation to the neural interference effect and the neural problem size effect. To that end, we used a paradigm developed by De Visscher, Berens, et al. (2015) that contrasts the interference effect and the problem size effect in a multiplication verification task, during functional magnetic resonance imaging (fMRI) acquisition. Forty-two healthy adults, who showed high variability in an arithmetic fluency test, participated in our fMRI study. In order to control for the general reasoning level, the IQ was taken into account in the individual differences analyses. Our findings revealed a neural interference effect linked to individual differences in multiplication in the left inferior frontal gyrus, while controlling for the IQ. This interference effect in the left inferior frontal gyrus showed a negative relation with individual differences in arithmetic fluency, indicating a higher interference effect for low performers compared to high performers. This region is suggested in the literature to be involved in resolution of proactive interference. Besides, no correlation between the neural problem size effect and multiplication performance was found. This study supports the idea that the interference due to similarities/overlap of physical traits (the digits) is crucial in memorizing arithmetic facts and in determining individual differences in arithmetic. PMID- 29444467 TI - Olfactory function in systemic lupus erythematosus and systemic sclerosis. A longitudinal study and review of the literature. AB - BACKGROUND/PURPOSE: To evaluate olfactory function in systemic lupus erythematosus (SLE), systemic sclerosis (SSc) and healthy controls over a 2-year period, and to determine the association of olfactory dysfunction with age, disease activity, disease damage, treatment, anxiety and depression symptoms and limbic structures volumes. METHODS: Consecutive SLE and SSc patients were enrolled in this study. Clinical, laboratory disease activity and damage were assessed according to diseases specific guidelines. Olfactory functions were evaluated using the Sniffin' Sticks test (TDI). Volumetric magnetic resonance imaging (MRI) was obtained in a 3T Phillips scanner. Amygdalae and hippocampi volumes were analyzed using FreeSurfer(r) software. RESULTS: We included 143 SLE, 57 SSc and 166 healthy volunteers. Olfactory dysfunction was observed in 78 (54.5%) SLE, 35 (59.3%) SSc patients and in 24 (14.45%) controls (p<0.001) at study entry. SLE and SSc patients had significantly lower mean in all three phases (TDI) of the olfactory assessment when compared with healthy volunteers. In SLE, the presence of olfactory dysfunction was associated with older age, disease activity, higher anxiety and depression symptoms score, smaller left hippocampus volume, smaller left and right amygdalae volume and the presence of anti-ribosomal P (anti-P) antibodies. In SSc the presence of olfactory impairment was associated with older age, disease activity, smaller left and right hippocampi volumes and smaller right amygdala volume. Olfactory function was repeated after a 2-year period in 90 SLE, 35 SSc and 62 controls and was stable in all three groups. CONCLUSION: Both SLE and SSc patients with longstanding disease had significant reduction in all stages of TDI that maintained stable over a 2-year period. Olfactory dysfunction was associated with age, inflammation and hippocampi and amygdalae volumes. In SLE, additional association with anti-P, anxiety and depression symptoms was observed. PMID- 29444468 TI - A major component of vitamin E, alpha-tocopherol inhibits the anti-tumor activity of crizotinib against cells transformed by EML4-ALK. AB - Crizotinib is an inhibitor of anaplastic lymphoma kinase (ALK) and is of significant therapeutic benefit to patients with non-small cell lung cancer (NSCLC) harboring the EML4-ALK fusion gene. In the present study, we demonstrated that alpha-tocopherol, a major component of vitamin E, attenuated the effects of crizotinib independently of its anti-oxidant properties. alpha-Tocopherol significantly inhibited crizotinib-induced apoptosis in cells transformed by EML4 ALK. It also effectively attenuated the crizotinib-induced inhibition of EML4-ALK and its downstream molecules, STAT3 and ERK, and suppressed the inhibitory effects of crizotinib on EML4-ALK-mediated transformation in the focus formation assay. On the other hand, other members of the vitamin E family, namely, beta tocopherol, gamma-tocopherol, delta-tocopherol, and alpha-tocotrienol, and a water-soluble analog of vitamin E, Trolox had no effects on the anti-tumor activity of crizotinib in cells transformed by EML4-ALK. Collectively, these results revealed the risk of the anti-tumor activity of crizotinib being attenuated when it is administrated in combination with vitamin E supplements containing alpha-tocopherol as a major component.

AB - Diabetic nephropathy (DN) is one of the most severe microangiopathies of diabetes mellitus and is a leading cause of end stage renal disease. Numerous studies suggest that podocyte injury contributes to progressive proteinuria. Podocytes are highly specialized, terminally differentiated cells that are unable to proliferate, autophagy plays a key role in maintaining the structure and function of podocytes. Autophagy impairment is involved in the pathogenesis of podocyte loss, which leads to massive proteinuria in DN. In the present study, we investigated the effects of mangiferin on nephropathy in streptozotocin (STZ) induced diabetic rats; we focused on pathological factors related to autophagy in podocytes and the AMPK-mTOR-ULK1 pathway. The results showed that chronic treatment with mangiferin significantly decreased albuminuria, inhibited glomerular extracellular matrix expansion and restored the expression of nephrin, a podocyte marker, in diabetic rats; these results suggest that mangiferin delayed the process of DN and protected the podocytes. In addition, mangiferin induced autophagy, as shown by the up-regulation of LC3 II and the down regulation of p62 in both DN rats and podocytes. Transmission electron microscope analyses showed that mangiferin increased the number of autophagosomes in the podocytes of DN rats. This underlying mechanism was associated with the up regulation of AMPK phosphorylation, the down-regulation of mTOR phosphorylation and the up-regulation of p-ULK1. Taken together, mangiferin delayed the progression of DN and protected the podocytes by enhancing autophagy under diabetic conditions via the AMPK-mTOR-ULK1 pathway. These findings provide new insights into the molecular mechanisms underlying the renoprotective effects of mangiferin in DN. PMID- 29444470 TI - Effect of sirolimus on liver cirrhosis and hepatic encephalopathy of common bile duct-ligated rats. AB - Cirrhosis is often associated with portal hypertension and portal-systemic collateral vessels formation attributed to angiogenesis, which leads to severe complications as hepatic encephalopathy. Sirolimus has anti-fibrosis and anti angiogenesis effects, but whether it influences the severity of portal-systemic collaterals and hepatic encephalopathy is unknown. This study was thus designed to address this issue in rats with common bile duct ligation-induced liver cirrhosis. Sham-operated rats were surgical controls. Rats were intraperitoneally administered with 0.5 and 2 mg/kg/day sirolimus or vehicle for 2 weeks. Four weeks post operations, motor activities, body weight, biochemistry and hemodynamic data were measured. The liver was dissected for histopathology, immunohistochemical stains and protein analysis. On the parallel cirrhotic groups, the portal-systemic shunting was determined. The results showed that the body weight gain was significantly lower in sirolimus-treated rats. Sirolimus reduced portal pressure and plasma levels of alanine aminotransferase, aspartate aminotransferase and ammonia, and attenuated hepatic inflammation and fibrosis in cirrhotic rats. In addition, the hepatic phosphorylated mammalian target of rapamycin (mTOR) and P70S6K protein expressions were significantly downregulated and endothelial nitric oxide synthase (eNOS) expression upregulated by sirolimus. Sirolimus did not influence portal-systemic shunting and motor activities of cirrhotic rats. In conclusion, sirolimus significantly improved hepatic inflammation and fibrosis accompanied by portal pressure reduction in cirrhotic rats, in which down-regulated mTOR/P70S6K and up-regulated eNOS expressions might play a role. However, sirolimus did not significantly change the severity of portal-systemic collaterals and motor activities, suggesting that the multifactorial pathogenesis of hepatic encephalopathy could not be fully overcome by sirolimus. PMID- 29444471 TI - Optimization of the polysaccharide hydrolysate from Auricularia auricula with antioxidant activity by response surface methodology. AB - An efficient acid-hydrolysis method was developed and optimized for the hydrolyses of polysaccharide from Auricularia auricula with the ABTS. scavenging ability as the detective marker. Based on the single factor experimental results, Box-Behnken design (BBD) were applied for the optimization of acid-hydrolysis conditions. The possible antioxidant mechanism of the hydrolyses (AAPs-F) in vivo was performed using the C. elegans model. The acid-hydrolysis conditions were found to be the optimal hydrolyzing time 2.78h (166.8min), hydrolyzing temperature 95.04 degrees C and the acid concentration 14.03mol/L, respectively. Under the optimal acid-hydrolysis conditions, the ABTS. scavenging ability of AAPs-H was 97.94+/-0.87%, which was well matched with the predicted value (99.77%) of the BBD model. AAPs-F was the main fraction of AAPs-H separated through Sephadex G-10 as the stationary phase. AAPs-F was a kind of heteropolysaccharide and comprised of glucose, galactose and fucose with the molar ratio of 50:1:2. The molecular weight of AAPs-F was 143.15kDa. AAPs-F showed a remarkable protective effect to the injury induced by hydrogen peroxide or paraquat (p<0.01), and it could up-regulate stress-resistance related enzymes including superoxide dismutase (SOD) by 109.74% and CAT by 106.84% at concentration of 0.2mg/mL in C. elegans. PMID- 29444472 TI - Low-resolution SAXS and comparative modeling based structure analysis of endo beta-1,4-xylanase a family 10 glycoside hydrolase from Pseudopedobacter saltans comb. nov. AB - The structure and biophysical properties of endo beta-1,4-xylanase (PsGH10A) of family 10 glycoside hydrolase were characterized. The modeled PsGH10A structure showed classical (beta/alpha)8-barrel fold. Ramachandran plot displayed 99.1% residues in favored and 0.3% in the generously allowed region and only 0.6% residues in disallowed region. The secondary structure analysis of PsGH10A by CD revealed 31.75% alpha-helices 20.0% beta-strands and 48.25% random coils. Protein melting study of PsGH10A showed complete unfolding at 60 degrees C and did not require any metal ion for its stability. Structural superposition and docking analysis confirmed the involvement of Glu156 and Glu263 residues in catalysis. SAXS analysis displayed that PsGH10A is monomeric in nature showing fully folded state in solution form. Guinier analysis gave the radius of gyration (Rg) 2.23 2.29nm. Kratky plot indicated that the protein is fully folded globular shaped and flexible in solution form. The ab initio derived dummy model of PsGH10A displayed chicken thigh like shape. The ab initio derived dummy model superposed well with its comparative modeled structure except the N-terminal His-tag region. PMID- 29444473 TI - Adhesive properties of calcium pectinate gels prepared from callus cultures pectins. AB - The aim of this research is to investigate the influence of the surface morphology of the calcium pectinate gel (CaPG) beads as well as the physicochemical characteristics of pectins and the CaPG beads on the adhesive properties of gels against the Gram-negative bacteria Escherichia coli and the Gram-positive bacteria Bacillus subtilis. The adhesion of the bacteria depends on the type of pectin and the surface morphology of the beads. The faster adhesion on CaPG beads appeared to be related to a lower degree of methyl esterification (DE), a higher molecular weight (Mw) and specific viscosity of the pectin and a higher gel strength. Surface roughness measurements were performed using an atomic force microscope. The beads from pectins with a higher Mw, a higher specific viscosity and a lower DE had a higher surface roughness. The surface roughness was one of the factors promoting adhesion of the bacteria onto the calcium pectinate gels. The surface morphology was observed under a scanning electron microscope (SEM). SEM images illustrated that E. coli and B. subtilis adhered on the beads with a rough surface. CaPG beads obtained from callus culture pectins can be proposed for the preparation of gels with adhesive and antiadhesive properties. PMID- 29444474 TI - DNA-directed trypsin immobilization on a polyamidoamine dendrimer-modified capillary to form a renewable immobilized enzyme microreactor. AB - A novel type of trypsin capillary microreactor was developed based on a DNA directed immobilization (DDI) technique applied to a fused-silica capillary modified with polyamidoamine (PAMAM) dendrimers. Trypsin binding to the inner wall of the capillary was confirmed by confocal laser scanning microscopy. The properties of the trypsin-DNA conjugated, PAMAM-modified capillary microreactor were investigated by monitoring hydrolysis of Nalpha-benzoyl-L-arginine ethyl ester. Through the hybridization and dehybridization of the DNA, the inner wall of the capillary functionalized with trypsin can be regenerated, thus indicating the renewability of this enzyme microreactor. In addition, these results demonstrated that introduction of PAMAM enabled higher amounts of trypsin to be immobilized, markedly improving the enzymolysis efficiency, compared with traditional modified capillaries. The digestion performance of the trypsin capillary microreactor was further evaluated by digesting cytochrome C, and a peptide numbers of 8, and a sequence coverage of 59% were obtained. This renewable and efficient immobilized trypsin capillary microreactor combines advantages of both DDI technology and PAMAM, and is potentially adaptable to high throughput enzyme assays in biochemical and clinical research.

PMID- 29444477 TI - The microbiome in chronic kidney disease patients undergoing hemodialysis and peritoneal dialysis. AB - Chronic kidney disease (CKD) is associated with an imbalanced human microbiome due not only to CKD-associated factors such as uremia, increased inflammation and immunosuppression, but also to pharmacological therapies and dietary restrictions. End-stage renal disease patients require renal replacement therapies commonly in the form of hemodialysis (HD) or peritoneal dialysis (PD). HD implies the existence of a vascular access, such as an arteriovenous fistula/graft or a venous catheter, whereas PD implies a long-term peritoneal catheter and the constant inflow of peritoneal dialysate. Also, dietary adaptations are mandatory in both therapies. This revision explores the impact of HD or PD therapies on human microbiome. HD and PD appear to be associated with different changes in the gut microbiome, for example a decrease in Proteobacteria relative abundance in HD patients and increase in PD patients. Both therapies may also have an impact on the human microbiome beyond the gut, leading to increased relative abundance of specific bacteria in the blood microbiome of HD patients and increased relative abundance of other bacteria in the peritoneal microbiome of PD patients. HD and PD catheter biofilms may also play an important role in the changes observed in these microbiomes. A more interdisciplinary approach is needed to further clarify the role of microbial groups other than bacteria in all body habitats to allow the complete understanding of the impact of HD or PD on the microbiome of CKD patients. Moreover, strategies that promote a healthy balance of the human microbiome on these patients should be explored. PMID- 29444478 TI - Detection of drug safety signals from clinical trials data: Role of SUSARs. AB - One of the main goals of safety management in clinical trials is to detect suspected unexpected serious adverse reactions (SUSARs). The unexpectedness concerns the nature, frequency or severity of an adverse reaction. Drug safety signals could thus be retrieved, and a study was performed to investigate whether SUSARs allow signal detection in pharmacovigilance. Data from six academic safety units were collected from 2005 to 2016. Characteristics of SUSARs were analysed and signals were identified i) by evaluating the presence of other causes, ii) by assessing the summary of product characteristics (SPC), iii) by searching for specific safety information in Pubmed and health agencies, and iv) by investigating the narrative of each case. Pharmacological plausibility was evaluated by compatible mechanism of reaction and time-to-onset. During the study period, 211 SUSARs were collected. They mostly concerned general disorders (26.1%) and protein kinase inhibitors (24.6%). After eliminating SUSARs with other causes or those considered as expected, 50 SUSARs (23.7%), involving a total of 115 drug-reaction pairs, concerned potential safety signals. Among these pairs, 12 (10.4%) were considered as pharmacologically plausible. This study indicates that one quarter of SUSARs collected in academic clinical trials refers to potential safety signals, especially for oncologic drugs. One tenth of drug reaction pairs was considered to have a pharmacological plausibility and could merit further evaluation. This is the first study suggesting that SUSARs could be a source of safety signals and that their routine analysis should be complementary to spontaneous reporting. PMID- 29444479 TI - Prevalence and correlates of burnout in health professionals in Ecuador. AB - BACKGROUND: Although burnout is a widespread phenomenon among healthcare professionals, there are no studies about its prevalence in Ecuador. This study assesses the prevalence of burnout syndrome among Ecuadorian healthcare professionals and examine the relationship with their personal and organizational characteristics. METHODS: A total of 2404 healthcare professionals (average age 40.0years; 68.4% women) from the capitals of all 24 provinces in Ecuador participated in this study. Trained psychologists assessed the presence of burnout by applying the Maslach Burnout Inventory. Sociodemographic variables, emotional distress, social support and coping styles as well as organizational variables were also collected. RESULTS: Of all healthcare professionals surveyed, 2.6% presented burnout syndrome. By dimensions, 17.2% of the participants presented a high level of emotional exhaustion, 13.5% of depersonalization, and 18.2% had reduced personal accomplishment. Being non-mestizo, being classified as a probable case of mental disorder and using more passive coping were associated with a greater probability of presenting burnout; having >10years of experience was associated with a lower probability of burnout. CONCLUSIONS: A significant number of active health professionals suffer from burnout. It is necessary to develop effective psychotherapeutic interventions for those who have the syndrome and to evaluate potential prevention strategies in those who have not yet developed it. PMID- 29444481 TI - Extreme weather impacts on tropical mangrove forests in the Eastern Brazil Marine Ecoregion. AB - Extreme weather events are likely to become more frequent in the 21st century bringing significant impacts to coastal ecosystems. However, the capacity to detect and measure those impacts are still limited, with effects largely unstudied. In June 2016, a hailstorm with wind gusts of over 100 km.h-1 caused an unprecedented mangrove dieback on Eastern Brazil. To quantify the scale of impact and short-term recovery of mangroves (15-mo), we used satellite imagery and field sampling to evaluate changes in forest structure in control and impacted areas after the hailstorm. Satellite imagery revealed mangrove dieback in over 500 ha, corresponding to 29.3% of the total forest area suddenly impacted after the hailstorm. Fifteen months after the hailstorm, some impacted areas show an initial recovery, while others continued to degrade. The El Nino years of 2014 2016 created mild drought conditions in Eastern Brazil. As observed in wetlands of semi-arid regions during the same period, mangrove recovery may have been impaired by continued physiological stress and climate change effects. Economic losses in the study site from typical mangrove ecosystem services including food provision, climate regulation, raw materials and nurseries are estimated to at least US$ 792,624 yr-1. This is the first evidence of an extreme weather impact on mangroves in Brazil that typically provide unique ecological and economic subsistence to coastal populations. Our results reveal that there is a pressing need for long-term monitoring and climate change adaptation actions for coastal wetlands in Brazil, and to provide broad estimates of ecosystem values associated with these ecosystems given many areas are already experiencing chronic stress from local impacts, drought and high temperatures. PMID- 29444480 TI - Does crash risk increase when emergency vehicles are driving with lights and sirens? AB - INTRODUCTION: Emergency vehicles, such as police, ambulances, and fire vehicles, need to arrive at the scene of emergencies as quickly as possible, and thus they often travel in emergency mode - using their lights and sirens and often bypassing traffic signals. We examined whether travelling in emergency mode increased crash risk among police, ambulance and fire vehicles. METHODS: We conducted a quasi-induced exposure analysis using data from the Iowa Crash Database for the period of 2005 through 2013. The data are maintained by the Iowa Department of Transportation (IADOT), Office of Driver Services (ODS) and includes all investigating police officer's reports of motor vehicle crashes. The quasi-induced exposure method is an approach to calculate crash risk in the absence of exposure data using vehicles without a contributing cause (did not contribute to the crash) as a proxy for the baseline driving population. RESULTS: From 2005 - 2013, police vehicles were involved in 2406 crashes and ambulances and fire vehicles were involved in 528 crashes. Police vehicles were 1.8 times more likely to crash while driving in emergency mode than usual mode; this was a statistically significant increase. Ambulance and fire vehicles were not more likely to crash in emergency mode compared with usual mode. For police, other factors that contributed to crash risk included gender, age, icy/snowy roads, unpaved roads, and intersections. For ambulances and fire vehicles, other factors that contributed to crash risk included gender, age, weekends, icy/snowy roads and urban locations. CONCLUSION: Crash risk increased when police vehicles drove with lights and sirens but did not increase for ambulance and fire vehicles. Further research is necessary to develop and evaluate strategies to mitigate crash risk among police vehicles. Cultural approaches which prioritize transportation safety in conjunction with reaching the scene as quickly as possible may be warranted. PMID- 29444482 TI - Exposure and risk assessment to arsenic species in Spanish children using biomonitoring. AB - We present a new approach to arsenic (As) risk assessment using biomonitoring. In this pilot study we determined the levels of total and speciated urinary arsenicin 109 Spanish school children aged between 6 and 11 years, and interpreted these concentrations in a risk assessment context. The geometric mean (GM) for total As (TAs) was 33.82 MU/L. The order of occurrence and average concentrations of the different species was arsenobetaine (AsB) (100%, 15 MUg/L), dimethylarsinic (DMA) (97%, 8.32 MUg/L), monomethylarsonic (MMA) (26%, 0.27 MUg/L) and inorganic As (iAs) (4%, 0.14 MUg/L). 18% of children presented exposures to inorganic arsenic (7.52 MUg/g creatinine) higher than guidance value for non-cancer risk (8.3 MUg/g creatinine). For cancer risk the exposure to inorganic arsenic was much higher than the guidance value. Urinary DMA was positively associated with urinary AsB, suggesting exposure directly to this specie or metabolism of organic arsenicals to this specie, mainly through seafood consumption. Consequently, the exposure to inorganic As needs to be carefully interpreted because it may be overestimated. Our study supports the hypothesis that urinary iAs + MMA is the most reliable biomarker of exposure to inorganic As. PMID- 29444483 TI - Nitrifying activity and ammonia-oxidizing microorganisms in a constructed wetland treating polluted surface water. AB - Ammonia oxidation, performed by both ammonia oxidizing bacteria (AOB) and archaea (AOA), is an important step for nitrogen removal in constructed wetlands (CWs). However, little is known about the distribution of these ammonia oxidizing organisms in CWs and the associated wetland environmental variables. Their relative importance to nitrification in CWs remains still controversial. The present study investigated the seasonal dynamics of AOA and AOB communities in a free water surface flow CW (FWSF-CW) used to ameliorate the quality of polluted river water. Strong seasonality effects on potential nitrification rate (PNR) and the abundance, richness, diversity and structure of AOA and AOB communities were observed in the river water treatment FWSF-CW. PNR was positively correlated to AOB abundance. AOB (6.76*105-6.01*107 bacterial amoA gene copies per gram dry sediment/soil) tended to be much more abundant than AOA (from below quantitative PCR detection limit to 9.62*106 archaeal amoA gene copies per gram dry sediment/soil). Both AOA and AOB abundance were regulated by the levels of nitrogen, phosphorus and organic carbon. Different wetland environmental variables determined the diversity and structure of AOA and AOB communities. Wetland AOA communities were mainly composed of unknown species and Nitrosopumilus-like organisms, while AOB communities were mainly represented by both Nitrosospira and Nitrosomonas. PMID- 29444484 TI - Application of a new targeted low density microarray and conventional biomarkers to evaluate the health status of marine mussels: A field study in Sardinian coast, Italy. AB - In the present study, we investigated the health status of marine mussels (Mytilus galloprovincialis) caged and deployed at three different sites on the Sardinian coastline characterized by different levels of contamination: Fornelli (F, the reference site), Cala Real (CR), and Porto Torres (PT). A new low density oligonucleotide microarray was used to investigate global gene expression in the digestive gland of mussels. Target genes were selected to cover most of the biological processes involved in the stress response in bivalve mollusks (e.g. DNA metabolism, translation, immune response, cytoskeleton organization). A battery of classical biomarkers was also employed to complement the gene expression analyses. Chemical analysis revealed higher loads of heavy metals (Pb and Cu) and total polycyclic aromatic hydrocarbons (PAHs) at PT compared to the other sites. In mussels deployed at CR, functional genomics analysis of the microarray data rendered 78 differentially expressed genes (DEGs) involved in 11 biological processes. Animals exposed at PT had 105 DEGs that were characterized by the regulation of 14 biological processes, including mitochondrial activity, adhesion to substrate, DNA metabolism, translation, metal resistance, and cytoskeleton organization. Biomarker data (lysosomal membrane stability, lysosomal/cytoplasm volume ratio, lipofuscin accumulation, metallothionein content, micronucleus frequency, and cytoskeleton alteration) were in trend with transcriptomic output. Biomarker data were integrated using the Mussel Expert System (MES), allowing defining the area in which the presence of chemicals is toxic for mussels. Our study provides the opportunity to adopt a new approach of integrating transcriptomic (microarray) results with classical biomarkers to assess the impact of pollutants on marine mussels in biomonitoring programs. PMID- 29444485 TI - Estimating subcooled liquid vapor pressures and octanol-air partition coefficients of polybrominated diphenyl ethers and their temperature dependence. AB - Both subcooled liquid vapor pressure (PL) and octanol-air partition coefficient (KOA) are widely used as descriptors to predict gas-particle partitioning behavior of semi-volatile organic compounds (SVOCs), such as polybrominated diphenyl ethers (PBDEs). These two descriptors are functions of temperature, which are expressed as the Clausius-Clapeyron equations with the coefficients AL and BL for PL (log PL=AL+BL/T) and AO and BO for KOA (log KOA=AO+BO/T), where T is temperature in K. In this study, a simple equation to relate log KOA and log PL (log KOA=-log PL+6.46) was derived, which also links the coefficients of AL &BL and AO &BO. Regression analysis of published data of internal energy DeltaUOA for 22 PBDE congeners with their mole mass was made, leading a regression equation to calculate the internal energy for all 209 PBDE congeners. Three datasets of log KOA at 25 degrees C for all 209 PBDE congeners were evaluated; the one with the best match with experimentally measurements was selected. Using the datasets and equations described above, we calculated the values of Clausius Clapeyron coefficients AO &BO and AL &BL for all 209 PBDE congeners at the following steps. First, BO was computed using the values of DeltaUOA. Next, we calculated the values of AO using the values of BO and the values of log KOA at 25 degrees C. Finally, the values of the parameter AL and BL were determined for all 209 PBDE congeners. Results are in consistent with data available in the literature and the accuracy of the data were also evaluated. With these Clausius Clapeyron coefficients, the values of PL and KOA at any environmentally relevant temperature can be calculated for all 209 PBDE congeners, and thus provides a quick reference for environmental monitoring and modeling of PBDEs. PMID- 29444486 TI - Brook trout distributional response to unconventional oil and gas development: Landscape context matters. AB - We conducted a large-scale assessment of unconventional oil and gas (UOG) development effects on brook trout (Salvelinus fontinalis) distribution. We compiled 2231 brook trout collection records from the Upper Susquehanna River Watershed, USA. We used boosted regression tree (BRT) analysis to predict occurrence probability at the 1:24,000 stream-segment scale as a function of natural and anthropogenic landscape and climatic attributes. We then evaluated the importance of landscape context (i.e., pre-existing natural habitat quality and anthropogenic degradation) in modulating the effects of UOG on brook trout distribution under UOG development scenarios. BRT made use of 5 anthropogenic (28% relative influence) and 7 natural (72% relative influence) variables to model occurrence with a high degree of accuracy [Area Under the Receiver Operating Curve (AUC)=0.85 and cross-validated AUC=0.81]. UOG development impacted 11% (n=2784) of streams and resulted in a loss of predicted occurrence in 126 (4%). Most streams impacted by UOG had unsuitable underlying natural habitat quality (n=1220; 44%). Brook trout were predicted to be absent from an additional 26% (n=733) of streams due to pre-existing non-UOG land uses (i.e., agriculture, residential and commercial development, or historic mining). Streams with a predicted and observed (via existing pre- and post-disturbance fish sampling records) loss of occurrence due to UOG tended to have intermediate natural habitat quality and/or intermediate levels of non-UOG stress. Simulated development of permitted but undeveloped UOG wells (n=943) resulted in a loss of predicted occurrence in 27 additional streams. Loss of occurrence was strongly dependent upon landscape context, suggesting effects of current and future UOG development are likely most relevant in streams near the probability threshold due to pre-existing habitat degradation.

AB - Continuous directed evolution is the 'while loop' of synthetic biology, autonomous cycles of mutation, selection, and self-replication that can lead to the rapid development of industrially relevant organisms, pathways, or molecules. Although this engineering strategy requires particular mutagenesis methods and well-defined selections, recent advances have facilitated its implementation. Control over selection pressure has been augmented by novel cost-effective continuous culturing devices with open source designs. New in vivo targeted mutagenesis methods have enabled continuous directed protein evolution in various organisms. Furthermore, advances in automation have enabled rational, semi continuous directed evolution strategies that may yield fewer artefacts or parasites. Overall, continuous directed evolution is persistently demonstrating its capacity to rapidly generate biotechnologically valuable strains and proteins. PMID- 29444487 TI - Paracrine Fibroblast Growth Factor Initiates Oncogenic Synergy with Epithelial FGFR/Src Transformation in Prostate Tumor Progression. AB - Cross talk of stromal-epithelial cells plays an essential role in both normal development and tumor initiation and progression. Fibroblast growth factor (FGF) FGF receptor (FGFR)-Src kinase axis is one of the major signal transduction pathways to mediate this cross talk. Numerous genomic studies have demonstrated that expression levels of FGFR/Src are deregulated in a variety of cancers including prostate cancer; however, the role that paracrine FGF (from stromal cells) plays in dysregulated expression of epithelial FGFRs/Src and tumor progression in vivo is not well evaluated. In this study, we demonstrate that ectopic expression of wild-type FGFR1/2 or Src kinase in epithelial cells was not sufficient to initiate prostate tumorigenesis under a normal stromal microenvironment in vivo. However, paracrine FGF10 synergized with ectopic expression of epithelial FGFR1 or FGFR2 to induce epithelial-mesenchymal transition. Additionally, paracrine FGF10 sensitized FGFR2-transformed epithelial cells to initiate prostate tumorigenesis. Next, paracrine FGF10 also synergized with overexpression of epithelial Src kinase to high-grade tumors. But loss of the myristoylation site in Src kinase inhibited paracrine FGF10-induced prostate tumorigenesis. Loss of myristoylation alters Src levels in the cell membrane and inhibited FGF-mediated signaling including inhibition of the phosphotyrosine pattern and FAK phosphorylation. Our study demonstrates the potential tumor progression by simultaneous deregulation of proteins in the FGF/FGFRs/Src signal axis and provides a therapeutic strategy of targeting myristoylation of Src kinase to interfere with the tumorigenic process.

AB - Electrophysiological methods are the gold standard in neuroscience because they reveal the activity of individual neurons at high temporal resolution and in arbitrary brain locations. Microelectrode arrays based on complementary metal oxide semiconductor (CMOS) technology, such as Neuropixels probes, look set to transform these methods. Neuropixels probes provide ~1000 recording sites on an extremely narrow shank, with on-board amplification, digitization, and multiplexing. They deliver low-noise recordings from hundreds of neurons, providing a step change in the type of data available to neuroscientists. Here we discuss the opportunities afforded by these probes for large-scale electrophysiology, the challenges associated with data processing and anatomical localization, and avenues for further improvements of the technology. PMID- 29444490 TI - Systematic evaluation of matrix effects in supercritical fluid chromatography versus liquid chromatography coupled to mass spectrometry for biological samples. AB - Matrix effects (ME) is acknowledged as being one of the major drawbacks of quantitative bioanalytical methods, involving the use of liquid chromatography coupled to mass spectrometry (LC-MS). In the present study, the incidence of ME in SFC-MS/MS and LC-MS/MS in the positive mode electrospray ionization (ESI+) was systematically compared for the analysis of urine and plasma samples using two representative sets of 40 doping agents and 38 pharmaceutical compounds, respectively. Three different SFC stationary phase chemistries were employed, to highlight the importance of the column in terms of selectivity. Biological samples were prepared using two different sample treatments, including a non selective sample clean-up procedure (dilute and shoot (DS) and protein precipitation (PP) for urine and plasma samples, respectively) and a selective sample preparation, namely solid phase extraction (SPE) for both matrices. The lower susceptibility to ME in SFC vs. reversed phase LC (RPLC) was verified in all the experiments performed on urine, and especially when a simple DS procedure was applied. Also, with the latter, the performance strongly varied according to the selected SFC stationary phase, whereas the results were quite similar with the three SFC columns, in the case of SPE clean-up. The same trend was observed with plasma samples. Indeed, with the PP procedure, the occurrence of ME was different on the three SFC columns, and only the 2-picolylamine stationary phase chemistry displayed lower incidence of ME compared to LC-MS/MS. On the contrary, when a SPE clean-up was carried out, the results were similar to the urine samples, with higher performance of SFC vs. LC and limited discrepancies between the three SFC columns. The type of ME observed in LC-MS/MS was generally a signal enhancement and an ion suppression for urine and plasma samples, respectively. In the case of SFC-MS/MS, the type of ME randomly varied according to the analyzed matrix, selected column and sample treatment. PMID- 29444491 TI - Piecing together nonribosomal peptide synthesis. AB - Nonribosomal peptide synthetases (NRPSs) produce peptide products with wide ranging biological activities. NRPSs are macromolecular machines with modular assembly-line logic, a complex catalytic cycle, moving parts and multiple active sites. They are organized into repeating sets of domains, called modules. Each module contains all functionality to introduce a building block into the growing peptide, many also perform cosynthetic tailoring. Structures of individual domains have provided insights into their catalytic mechanisms, but with one exception, larger NRPS proteins were refractory to structure determination. Recently, structure determination succeeded for four multi-domain NRPS proteins: an alternative formylating initiation and two termination modules as well as a large cross-module construct. This review highlights how these data, together with novel didomain structures, contribute to a holistic view of the architecture, domain-domain interactions and conformational changes in NRPS megaenzymes.

AB - A new technique to identify the floral resources of honeys is demanded. Terahertz time-domain attenuated total reflection spectroscopy combined with chemometrics methods was applied to discriminate different categorizes (Medlar honey, Vitex honey, and Acacia honey). Principal component analysis (PCA), cluster analysis (CA) and partial least squares-discriminant analysis (PLS-DA) have been used to find information of the botanical origins of honeys. Spectral range also was discussed to increase the precision of PLS-DA model. The accuracy of 88.46% for validation set was obtained, using PLS-DA model in 0.5-1.5THz. This work indicated terahertz time-domain attenuated total reflection spectroscopy was an available approach to evaluate the quality of honey rapidly.

The proposed model was developed based on the optimal selection of crucial parameters and the combination of correlation coefficient method (CC), partial least squares regression (PLSR) and radial basis function neural network (RBFNN). To test the performance of the model, a standard NIR spectroscopy data set was introduced, containing spectral information and chemical reference measurements of 80 corn samples. For comparison, several other models based on the identical data set were also briefly discussed. In this process, the root mean square error of prediction (RMSEP) and coefficient of determination (Rp2) in the prediction set were used to make evaluations. As a result, the proposed model presented the best predictive performance with the smallest RMSEP (0.0497%) and the highest Rp2 (0.9968). Therefore, the proposed method combining NIR spectroscopy with the optimal CC-PLSR-RBFNN model can be helpful to determine starch content in corn.

AB - Human telomere DNA plays a vital role in genome integrity control and carcinogenesis as an indication for extensive cell proliferation. Herein, silver nanoclusters (Ag NCs) templated by polymer and unmodified gold nanoparticles (Au NPs) are designed as a new colorimetric platform for sensitively differentiating telomere DNA with different lengths, monitoring G-quadruplex and dsDNA. Ag NCs can produce the aggregation of Au NPs, so the color of Au NPs changes to blue and the absorption peak moves to 700nm. While the telomere DNA can protect Au NPs from aggregation, the color turns to red again and the absorption band blue shift. Benefiting from the obvious color change, we can differentiate the length of telomere DNA by naked eyes. As the length of telomere DNA is longer, the variation of color becomes more noticeable. The detection limits of telomere DNA containing 10, 22, 40, 64 bases are estimated to be 1.41, 1.21, 0.23 and 0.22nM, respectively. On the other hand, when telomere DNA forms G-quadruplex in the presence of K+, or dsDNA with complementary sequence, both G-quadruplex and dsDNA can protect Au NPs better than the unfolded telomere DNA. Hence, a new colorimetric platform for monitoring structure conversion of DNA is established by Ag NCs-Au NPs system, and to prove this type of application, a selective K+ sensor is developed.

AB - The first line defense mechanisms against viral infection are mediated by the innate immune system. Viral components are detected by infected cells and/or innate immune cells that express different sensory receptors. They in turn mediate induction of direct antiviral mechanisms and further modulation of innate and adaptive immune responses. For evading the innate system, most viruses have evolved efficient mechanisms to block sensing and/or antiviral functions of the innate response. Interestingly, hepatitis B virus (HBV) seems to act like a stealth virus that escapes cell intrinsic antiviral mechanisms through avoiding recognition by the innate system rather than blocking its effector functions. In line with this concept, agonistic activation of innate immunity has emerged as a promising novel anti-HBV therapy approach with several compounds having advanced to the clinical stage. PMID- 29444497 TI - Influence of the type of aqueous sodium silicate on the stabilization and rheology of kaolin clay suspensions. AB - To avoid agglomeration and sedimentation of grains, ceramic slurries should be modified by stabilizers in order to increase the electrostatic interactions between the dispersed particles. In this study we present the spectral analysis of aqueous sodium silicates obtained by different synthesis methods and their influence on the rheological properties of kaolin based slurries. Infrared and Raman spectra can be used to describe the structure of silicate structural units present in aqueous sodium silicates. It was confirmed that the best stabilization results possess aqueous sodium silicates of the silicate moduli of about 2 and the optimal concentration of the used fluidizer is 0.3wt% to the kaolin clay dry mass. One of the most important conclusions is that the synthesis method of the fluidizer has no significant effect on its stabilization properties but used medium does create adequate stabilization mechanism depending on the silicate structures present in the sodium silicate solution. PMID- 29444498 TI - A novel dicyanoisophorone based red-emitting fluorescent probe with a large Stokes shift for detection of hydrazine in solution and living cells. AB - A novel dicyanoisophorone based fluorescent probe HP was developed to detect hydrazine. Upon the addition of hydrazine, probe HP displayed turn-on fluorescence in the red region with a large Stokes shift (180nm). This probe exhibited high selectivity and high sensitivity to hydrazine in solution. The detection limit of HP was found to be 3.26ppb, which was lower than the threshold limit value set by USEPA (10ppb). Moreover, the probe was successfully applied to detect hydrazine in different water samples and living cells. PMID- 29444499 TI - Fine tuning the emission wavelengths of the 7-hydroxy-1-indanone based nano structure dyes: Near-infrared (NIR) dual emission generation with large stokes shifts. AB - Near-infrared (NIR) fluorescent dyes have recently gained special attention due to their applications to use as molecular probes for imaging of biological targets and sensitive determination. In this study, photophysical properties of the 7-hydroxy-1-indanone based fluorophors A1, A2, A3, B1, B2 and 3R-B2 (R=CF3, NH2, NO2 and OMe) in the gas and three solution phases were probed using TD-DFT method at PBE0/6-311++G(d,p) and M06-2X/6-311++G(d,p) levels of theory. In addition to structural and photophysical properties as well as ESIPT mechanism of all mentioned molecules, the FC and relaxed potential energy surfaces of B2 and 3R-B2 (R=CF3 and NH2) molecules were explored in gas phase and acetonitrile, cyclohexane and water solvents. It is predicted that the A1, A3 and 3R-B2 chromophores afford normal (615-670nm) and NIR fluorescence emissions (770-940nm; biological window) with the large Stokes shifts of >160 and >300nm, respectively. A good aggrement was found between theoretical and experimental results. In sum, these new types of dyes may render the new approaches for the development of the most efficient NIR fluorescent probes for enhanced image contrast and optimal apparent brightness in biological applications.

AB - Spinocerebellar ataxia type 3 (SCA3) is a dominantly inherited neurodegenerative disease caused by a CAG repeat expansion in the region of the ATXN3 gene. The main feature of SCA3 is progressive ataxia, which affects balance, gait, and speech. Urine cells (UCs) of a SCA3 patient were successfully translated to induced pluripotent stem cells (iPSCs) by using the Sendai virus delivery system. ZZUi004-A cell line may provide a robust platform for further study of SCA3 pathogenesis as well as drug testing and gene therapy research. PMID- 29444501 TI - Quercetin Therapy for Selected Patients with PIM1 Kinase-Positive Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma: A Pilot Study. AB - We reported that PIM1 kinase is expressed in the lymphocytes of patients with chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL). Quercetin, a naturally occurring flavonoid, is a dietary supplement and inhibits many kinases, including PIM1, in vitro. Under an Institutional Review Board-approved protocol, we performed an open-label, single-arm pilot study to evaluate the antitumor activity of quercetin in patients with CLL/SLL. Q-ForceTM chews were administered orally, 500 mg twice daily, for 3 months. Eligible patients had failed prior therapies, had had no other standard treatment, or refused other therapies. Response was assessed based on objective change in disease parameters. Patients were included if their lymphocyte counts were rising and >=10,000/uL but not > 100,000/uL. Three patients received quercetin treatment. There was no toxicity. Two responded with stabilization of rising lymphocyte counts (p < 0.001 for each), which remained stable during their follow-up (5 and 11 months after cessation of treatment, respectively). The CLL cells in the nonresponder harbored a TP53 mutation. Although our data from this pilot translational study are based on a small sample, further studies of quercetin as a potential therapeutic agent in selected patients with CLL/SLL appear warranted. PMID- 29444502 TI - Starch Combined with Sucrose Provokes Greater Root Dentine Demineralization than Sucrose Alone. AB - Since there is no consensus about whether starch increases the cariogenic potential of sucrose, we used a validated 3-species biofilm model to evaluate if starch combined with sucrose provokes higher root dentine demineralization than sucrose alone. Biofilms (n = 18) composed by Streptococcus mutans (the most cariogenic bacteria), Actinomces naeslundii (which has amylolytic activity), and Streptococcus gordonii (which binds salivary amylase) were formed on root dentine slabs under exposure 8 */day to one of the following treatments: 0.9% NaCl, 1% starch, 10% sucrose, or a combination of 1% starch and 10% sucrose. Before each treatment, biofilms were pretreated with human whole saliva for 1 min. The pH of the culture medium was measured daily as an indicator of biofilm acidogenicity. After 96 h of growth, the biofilms were collected, and the biomass, bacteria viability, and polysaccharides were analyzed. Dentine demineralization was assessed by surface hardness loss (% SHL). Biofilm bioarchitecture was analyzed using confocal laser scanning microscopy. Treatment with a starch and sucrose combination provoked higher (p = 0.01) dentine demineralization than sucrose alone (% SHL = 53.2 +/- 7.0 vs. 43.2 +/- 8.7). This was supported by lower pH values (p = 0.007) of the culture medium after daily exposure to the starch and sucrose combination compared with sucrose (4.89 +/- 0.29 vs. 5.19 +/- 0.32). Microbiological and biochemical findings did not differ between biofilms treated with the combination of starch and sucrose and sucrose alone (p > 0.05). Our findings give support to the hypothesis that a starch and sucrose combination is more cariogenic for root dentine than sucrose alone.

PMID- 29444504 TI - The SNP Rs915014 in MTHFR Regulated by MiRNA Associates with Atherosclerosis. AB - BACKGROUND/AIMS: The association between the genetic polymorphisms located in either the exon or untranslated region of MTHFR and the risk of human atherosclerosis has been well-documented. This study analyzed MTHFR polymorphisms at the 3'-untranslated region for association with risk and outcome of atherosclerosis in a Chinese Han population. METHODS: The hospital based case control study was conducted with 500 patients and 600 healthy volunteers as control enrolled. The genotyping was conducted by using Taqman probe. The potential interaction was predicted by multiple bioinformatics analysis. The relative expression of MTHFR was detected by qRT-PCR. Further confirmation was determined by dual-luciferase assay. The plasma homocysteine levels were assayed by ELISA. RESULTS: Cigarette smoking, alcohol consumption, diabetes, hypertension and low levels of serum high-density lipoprotein-C were associated with an increased risk of developing ischemic stroke. MTHFR rs915014 AG and GG genotypes were significantly associated with increased risk of rs915014 compared with the GG genotype. The qRT-PCR confirmed that MTHFR rs915014 AG or GG genotypes could facilitate miR-2861 binding leading to decreased MTHFR levels in cells. In addition, patients carrying the MTHFR rs915014 AG or GG genotypes were associated with accumulation of circulating tHcy volume and a poor atherosclerosis consequence. CONCLUSIONS: This study demonstrates that the MTHFR rs915014 is associated with increased risk of atherosclerosis and might be a shot term outcome biomarker for atherosclerosis patients. PMID- 29444506 TI - The Impact of Advanced Age on Driving Safety in Adults with Medical Conditions. AB - BACKGROUND: Adults aged 85 and older, often referred to as the oldest-old, are the fastest-growing segment of the population. The rapidly increasing number of older adults with chronic and multiple medical conditions poses challenges regarding their driving safety. OBJECTIVE: To investigate the effect of advanced age on driving safety in drivers with medical conditions. METHODS: We categorized 3,425 drivers with preexisting medical conditions into four age groups: middle aged (55-64 years, n = 1,386), young-old (65-74 years, n = 1,013), old-old (75-84 years, n = 803), or oldest-old (85 years and older, n = 223). All underwent a formal driving evaluation. The outcome measures included fitness to drive recommendation by the referring physician, comprehensive fitness to drive decision from an official driving evaluation center, history of motor vehicle crashes (MVCs), and history of traffic violations. RESULTS: The oldest-old reported more cardiopulmonary and visual conditions, but less neurological conditions than the old-old. Compared to the middle-aged, the oldest-old were more likely to be considered unfit to drive by the referring physicians (odds ratio [OR] = 4.47, 95% confidence interval [CI] 2.20-9.10) and by the official driving evaluation center (OR = 2.74, 95% CI 1.87-4.03). The oldest-old reported more MVCs (OR = 2.79, 95% CI 1.88-4.12) compared to the middle-aged. CONCLUSION: Advanced age adversely affected driving safety outcomes. The oldest-old are a unique age group with medical conditions known to interfere with safe driving. Driving safety strategies should particularly target the oldest-old since they are the fastest-growing group and their increased frailty is associated with severe or fatal injuries due to MVCs. PMID- 29444507 TI - High Uric Acid Inhibits Cardiomyocyte Viability Through the ERK/P38 Pathway via Oxidative Stress. AB - BACKGROUND/AIMS: Clinical studies have shown that hyperuricaemia is strongly associated with cardiovascular disease. However, the molecular mechanisms of high uric acid (HUA) associated with cardiovascular disease remain poorly understood. In this study, we investigated the effect of HUA on cardiomyocytes. METHODS: We exposed H9c2 cardiomyocytes to HUA, then cell viability was determined by MTT assay, and reactive oxygen species' (ROS) production was detected by a fluorescence assay. Western blot analysis was used to examine phosphorylation of extracellular signal-regulated kinase (ERK), p38, phosphatidylinositol 3-kinase (PI3K) and Akt. We monitored the impact of HUA on phospho-ERK and phospho-p38 levels in myocardial tissue from an acute hyperuricaemia mouse model established by potassium oxonate treatment. RESULTS: HUA decreased cardiomyocyte viability and increased ROS production in cardiomyocytes; pre-treatment with N-acetyl-L cysteine, a ROS scavenger, and PD98059, an ERK inhibitor, reversed HUA-inhibited viability of cardiomyocytes. Further examination of signal transduction pathways revealed HUA-induced ROS involved in activating ERK/P38 and inhibiting PI3K/Akt in cardiomyocytes. Furthermore, the acute hyperuricaemic mouse model showed an increased phospho-ERK/p38 level in myocardial tissues. CONCLUSION: HUA induced oxidative damage and inhibited the viability of cardiomyocytes by activating ERK/p38 signalling, for a novel potential mechanism of hyperuricaemic-related cardiovascular disease. PMID- 29444508 TI - Negative Aging Stereotypes Disrupt both the Selection and Execution of Strategies in Older Adults. AB - BACKGROUND: Age-based cognitive deficits are exacerbated by stereotype threat effects (i.e., the threat of being judged as cognitively incapable due to aging). We tested whether age-based stereotype threat effects can occur via impair- ing older adults' ability to select the best strategy and/or to execute strategies efficiently. METHODS: Older adults (age range: 64.3-89.5 years) were randomly assigned to a stereotype threat or control condition before taking an episodic memory task. They encoded pairs of concrete words and of abstract words, with either a repetition or an imagery strategy, and then took a cued-recall task. Whereas participants in experiment 1 could choose between these two strategies, those of experiment 2 were forced to use either the repetition or the imagery strategy. RESULTS: Our findings showed that age-based stereotype threat disrupts both the selection and execution of the most efficient, but also most resource demanding, imagery strategy, and that these stereotype threat effects were stronger on concrete words. CONCLUSION: Our findings have important implications to further understand age-based (and other) stereotype threat effects, and how noncognitive factors modulate age-related changes in human cognition. PMID- 29444509 TI - Associations Between Intravenous Iron, Inflammation and FGF23 in Non-Dialysis Patients with Chronic Kidney Disease Stages 3-5. AB - BACKGROUND/AIMS: Both iron deficiency and chronic inflammation are highly prevalent in patients with chronic kidney disease (CKD). The effect of intravenous iron infusion on mineral metabolism in CKD may be modified by inflammation. Intravenous iron theraphy may reduce peripheral degradation, secretion, clearence of iFGF23 and lead to hypophosphatemia. The aim of the study was to evaluate the effect of intravenous iron on mineral metabolism in CKD patients. METHODS: 35 non-dialysis patients with CKD stages 3-5. received 100 mg/24h of ferric oxide saccharated solution for 5 days. Serum calcium (Ca), phosphorus (P), parathormone (PTH), intact-FGF23 (iFGF23), C-terminal-FGF23 (cFGF23), bone alkaline phosphatase (BAP) and high-sensitive CRP were assessed on day 1 and 3 at baseline and 2 hours after each dose administration and once on day 6. Plasma iFGF23 and cFGF23, as well as serum BAP were measured with ELISA and other parameters with standard automated laboratory methods. RESULTS: Serum iFGF23 increased after iv iron on day 1 and 6 (from 268.9+/-446.5 to 326.3+/ 529.9 on day 1; p=0.05 and to 451.4+/-601 pg/mL on day 6; p=0.03). cFGF23 was reduced only on day 1 (from 654.3+/-441.3 to 473.6+/-414 RU/mL; p=0.016). P concentration decreased significantly two hours after the first iron infusion (from 1.69+/-0.5 to 1.54+/-0.35 mmol/l; p=0.003). In following days the changes of cFGF23, P and of other calcium-phosphate metabolism were not significant. Serum CRP correlated neither with iFGF-23 nor cFGF-23. CONCLUSION: Intravenous iron supplementation may only transiently affect the production and degradation of FGF23 resulting in hypophosphatemia at the commencement of iron therapy. Chronic low-grade inflammation does not seem to play a role in that mechanism. PMID- 29444510 TI - Evaluating Serious Adverse Drug Reactions. PMID- 29444511 TI - Analysis of 10 Adrenocortical Carcinoma Patients in the Cohort of the Precision Medicine Platform MONDTI. AB - OBJECTIVE: Adrenocortical carcinoma (ACC) is a rare disease with a dismal prognosis. We aimed to evaluate if a personalized medicine approach may be useful for matching patients with ACC to targeted therapies. METHODS: This is an analysis of 10 molecularly profiled ACCs that were progressing under standard of care treatment. The profile consisted of a 50-gene next-generation sequencing panel, immunohistochemistry (IHC), and fluorescence in situ hybridization for several proteins or chromosomal aberrations. RESULTS: In 6 (60%) tumor samples, no somatic mutation was detected, while in 3 (30%) tumors 1 mutation was detected and in 1 (10%) tumor 2 mutations were detected. These mutations were CTNNB1 (2 samples), TP53 (1 sample), RB1 (1 sample) and APC (1 sample). Expression of phospho-mTOR and of EGFR was commonly detected by IHC (87.5 and 62.5%). In 4 (50%) samples, IHC revealed a weak expression of progesterone receptor. Less frequent alterations were expression of PDGFR-alpha, c-KIT, and estrogen receptor, each in 1 case. CONCLUSIONS: Based on the molecular profile, no recommendation for targeted therapy was made by the multi-disciplinary team. Currently, ACC might not be suitable for a precision medicine approach according to our tests. PMID- 29444512 TI - A Phase II Study of Irinotecan for Patients with Previously Treated Small-Cell Lung Cancer. AB - OBJECTIVE: Chemotherapy with irinotecan plus cisplatin has shown promise in chemo naive small-cell lung cancer (SCLC) patients. However, irinotecan treatment for relapsed or refractory SCLC has not been adequately evaluated. This phase II study evaluated the appropriate treatment schedule of irinotecan as a single agent. This study was designed to determine the antitumor activity, toxicity, and survival in previously treated SCLC patients. METHODS: Previously treated SCLC patients with at least one platinum-based regimen received irinotecan (100 mg/m2) on days 1 and 8, every 3 weeks, until disease progression. The assessment of the response rate was the primary endpoint. RESULTS: Thirty patients were enrolled, with an objective response rate of 41.3% (95% confidence interval [CI] 25.5 59.3), and a disease control rate of 69%. Median progression-free and overall survival was 4.1 months (95% CI, 2.2-5.4) and 10.4 months (95% CI, 8.1-14), respectively. The grade 3/4 hematological toxicities were neutropenia (36.7%), thrombocytopenia (3.3%), anemia (13.3%), and febrile neutropenia (6.6%). There were no grade 4 nonhematological toxicities. Frequent grade 3 nonhematological toxicities included diarrhea (10%), anorexia (6.6%), and hyponatremia (6.6%). CONCLUSIONS: This phase II study showed a high objective response rate and long survival. Irinotecan monotherapy schedule used was well tolerated, and could be an active treatment option for these patients. PMID- 29444514 TI - Abstracts of the 9th Workshop Probiotics and Prebiotics. PMID- 29444513 TI - Comparison of Three Methods Estimating Baseline Creatinine For Acute Kidney Injury in Hospitalized Patients: a Multicentre Survey in Third-Level Urban Hospitals of China. AB - BACKGROUND/AIMS: A lack of baseline serum creatinine (SCr) data leads to underestimation of the burden caused by acute kidney injury (AKI) in developing countries. The goal of this study was to investigate the effects of various baseline SCr analysis methods on the current diagnosis of AKI in hospitalized patients. METHODS: Patients with at least one SCr value during their hospital stay between January 1, 2011 and December 31, 2012 were retrospectively included in the study. The baseline SCr was determined either by the minimum SCr (SCrMIN) or the estimated SCr using the MDRD formula (SCrGFR-75). We also used the dynamic baseline SCr (SCrdynamic) in accordance with the 7 day/48 hour time window. AKI was defined based on the KDIGO SCr criteria. RESULTS: Of 562,733 hospitalized patients, 350,458 (62.3%) had at least one SCr determination, and 146,185 (26.0%) had repeat SCr tests. AKI was diagnosed in 13,883 (2.5%) patients using the SCrMIN, 21,281 (3.8%) using the SCrGFR-75 and 9,288 (1.7%) using the SCrdynamic. Compared with the non-AKI patients, AKI patients had a higher in-hospital mortality rate regardless of the baseline SCr analysis method. CONCLUSIONS: Because of the scarcity of SCr data, imputation of the baseline SCr is necessary to remedy the missing data. The detection rate of AKI varies depending on the different imputation methods. SCrGFR-75 can identify more AKI cases than the other two methods. PMID- 29444515 TI - Comprehensive miRNA Analysis of Human Umbilical Cord-Derived Mesenchymal Stromal Cells and Extracellular Vesicles. AB - BACKGROUND/AIMS: Mesenchymal stromal cells (MSCs) participate in the tissue specific repair of many different organs, especially the kidney. Their effects are primarily mediated by the paracrine release of factors including extracellular vesicles (EVs), which are composed of micro-vesicles and exosomes. The corresponding microRNAs (miRNAs) of EVs are considered important for their biological functions. METHODS: MSCs were cultured from the human umbilical cord, and EVs were isolated from the medium. The expression levels of miRNAs in MSCs and EVs were determined by microarray analysis, and gene ontology (GO) was used to analyze the functions of their target genes. RESULTS: MSCs and EVs had similar miRNA expression profiles, with the exception of a small number of selectively enriched miRNAs. GO analysis indicated that, unlike MSCs, the target genes of EV enriched miRNAs were associated with calcium channel regulation and cell junction activities, which may indicate that MSC and EVs have different regulatory properties. Angiogenesis, oxidative stress, and inflammatory signaling pathways related to the repair of renal injury were also analyzed, and EV-enriched miRNAs targeted genes associated with oxidative stress, T cell activation, and Toll-like receptor signaling. The miRNAs enriched in both MSCs and EVs targeted different genes in signaling pathways regulating angiogenesis and chemokine release. CONCLUSION: MSCs and their EVs shared similar miRNA component, and some selectively enriched miRNAs observed in MSCs and EVs may affect different target genes through some specific signaling pathways. PMID- 29444516 TI - Cardiac Magnetic Resonance Imaging of the Myocardium in Chronic Kidney Disease. AB - Early stages of chronic kidney disease (CKD) are often underdiagnosed, while their deleterious effects on the cardiovascular (CV) system are already at work. Thus, the assessment of early CV damage is of crucial importance in preventing major CV events. Myocardial fibrosis is one of the major consequences of progressive CKD, as it may lead to reentry arrhythmias and long-term myocardial dysfunction predisposing to sudden death and/or congestive heart failure. Subclinical myocardial fibrosis, with a potential key role in the development of uraemic cardiac disease, can be measured and characterised by appropriate cardiac magnetic resonance (CMR) techniques. Fibrosis detection was initially based on the contrast agent gadolinium, due to the superiority in sensitivity and accuracy of contrast-based methods in fibrosis assessment relative to native techniques. However, the severe consequences of gadolinium administration in uraemia (nephrogenic systemic fibrosis) have forced practitioners to re-evaluate the methodology. In the present overview, we review the possible contrast-based and contrast agent-free CMR techniques, including native T1 relaxation time, extracellular volume and global longitudinal strain measurement. The review also summarises their potential clinical relevance in CKD patients based on recently published studies. PMID- 29444517 TI - Acetyl-CoA Synthetase 2 Promotes Cell Migration and Invasion of Renal Cell Carcinoma by Upregulating Lysosomal-Associated Membrane Protein 1 Expression. AB - BACKGROUND/AIMS: Reprogramming energy metabolism is an emerging hallmark of many cancers, and this alteration is especially evident in renal cell carcinomas (RCCs). However, few studies have been conducted on lipid metabolism. This study investigated the function and mechanism of lipid metabolism-related acetyl-CoA synthetase 2 (ACSS2) in RCC development, cell migration and invasion. METHODS: Quantitative real-time PCR (qRT-PCR) was used to determine the expression of ACSS2 in cancer tissue and adjacent tissue. The inhibition of ACSS2 expression was achieved by RNA interference, which was confirmed by qRT-PCR and Western blotting. Cell proliferation and apoptosis were detected by a CCK8 assay and a flow cytometry analysis, respectively. Cell migration and invasion were determined by the scratch and transwell assays. Following the knockdown of ACSS2 expression, the expression of the autophagy-related factor LAMP1 was measured by qRT-PCR and Western blotting. RESULTS: Compared to adjacent tissues, ACSS2 expression was upregulated in RCC cancer tissues and positively correlated with metastasis. Inhibition of ACSS2 had no effect on RCC cell proliferation or apoptosis. However, decreased ACSS2 expression was found to inhibit RCC cell migration and invasion. ACSS2 was determined to promote the expression of LAMP1, which can also promote cell migration. This pathway may be considered a potential mechanism through which ACSS2 participates in RCC development. CONCLUSION: These data suggest that ACSS2 is an important factor for promoting RCC development and is essential for cell migration and invasion, which it promotes by increasing the expression of LAMP1. Taken together, these findings reveal a potential target for the diagnosis and treatment of RCC. PMID- 29444518 TI - Effects of Environmental Enrichment on Nicotine Sensitization in Rats Neonatally Treated with Quinpirole: Analyses of Glial Cell Line-Derived Neurotrophic Factor and Implications towards Schizophrenia. AB - The current study analyzed the effects of environmental enrichment versus isolation housing on the behavioral sensitization to nicotine in the neonatal quinpirole (NQ; dopamine D2-like agonist) model of dopamine D2 receptor supersensitivity, a rodent model of schizophrenia. NQ treatment in rats increases dopamine D2 receptor sensitivity throughout the animal's lifetime, consistent with schizophrenia. Animals were administered NQ (1 mg/kg) or saline (NS) from postnatal day (P)1 to P21, weaned, and immediately placed into enriched housing or isolated in wire cages throughout the experiment. Rats were behaviorally sensitized to nicotine (0.5 mg/kg base) or saline every consecutive day from P38 to P45, and brain tissue was harvested at P46. Results revealed that neither housing condition reduced nicotine sensitization in NQ rats, whereas enrichment reduced sensitization to nicotine in NS-treated animals. The nucleus accumbens (NAcc) was analyzed for glial cell line-derived neurotrophic factor (GDNF), a neurotrophin important in dopamine plasticity. Results were complex, and revealed that NAcc GDNF was increased in animals given nicotine, regardless of housing condition. Further, enrichment increased GDNF in NQ rats regardless of adolescent drug treatment and in NS-treated rats given nicotine, but did not increase GDNF in NS-treated controls compared to the isolated housing condition. This study demonstrates that environmental experience has a prominent impact on the behavioral and the neural plasticity NAcc response to nicotine in adolescence.

PMID- 29444520 TI - Remodeling of Wall Mechanics and the Myogenic Mechanism of Rat Intramural Coronary Arterioles in Response to a Short-Term Daily Exercise Program: Role of Endothelial Factors. AB - PURPOSE: Exercise elicits early adaptation of coronary vessels enabling the coronary circulation to respond adequately to higher flow demands. We hypothesized that short-term daily exercise induces biomechanical and functional remodeling of the coronary resistance arteries related to pressure. METHODS: Male rats were subjected to a progressively increasing 4-week treadmill exercise program (over 60 min/day, 1 mph in the final step). In vitro pressure-diameter measurements were performed on coronary segments (119 +/- 5 MUm in diameter at 50 mm Hg) with microarteriography. The magnitude of the myogenic response and contribution of endogenous nitric oxide and prostanoid production to the wall mechanics and pressure-diameter relationship were assessed. RESULTS: Arterioles isolated from exercised ani mals - compared to the sedentary group - had thicker walls, increased distensibility, and a decreased elastic modulus as a result of reduced wall stress in the low pressure range. The arterioles of exercised rats exhibited a more powerful myogenic response and less endogenous vasoconstrictor prostanoid modulation at higher pressures, while vasodilator nitric oxide modulation of diameter was augmented at low pressures (< 60 mm Hg). CONCLUSIONS: A short-term daily exercise program induces remodeling of rat intramural coronary arterioles, likely resulting in a greater range of coronary autoregulatory function (constrictor and dilator reserves) and more effective protection against great changes in intraluminal pressure, contributing thereby to the optimization of coronary blood flow during exercise. PMID- 29444521 TI - Non-Answered Questions in Patients with Endobronchial Valve Placement for Lung Volume Reduction. AB - Endoscopic lung volume reduction is a minimally invasive procedure performed to reduce the space occupied by the emphysemas' lobes. This procedure has been demonstrated to be beneficial for patients with advanced chronic obstructive pulmonary disease and severe hyperinflation. The use of endobronchial valves is increasing, as well as the number of reports of adverse events. The most common complications after the procedure are a pneumothorax, bleeding, infections, the need for valve removal, and valve expulsion. We have recently treated a patient who achieved immediate left upper lobe atelectasis but developed a pneumothorax on the 6th day and near-fatal kinking of the left lower lobe bronchus. This patient had asphyctic episodes probably due to a functional left pneumonectomy. We should consider this unusual complication in patients undergoing endoscopic lung volume reduction whose condition worsens after achieving complete lobar atelectasis.

AB - AIMS: This study aimed to investigate the mediating pathway of 3 factors (psychotic symptoms, attitude toward medication, and cognitive processing speed) on the effect of insight on personal-social functioning in patients with schizophrenia. METHODS: Chinese inpatients with schizophrenia (n = 168; mean age 18 +/- 50 years) diagnosed according to the DSM-IV were randomly assigned to treatment with antipsychotic medication alone or combined treatment. Positive and Negative Syndrome Scale (PANSS), Drug Attitude Inventory (DAI), Assessment of Insight (SAI), and Social-Personal Performance Scale (PSPS) scores were evaluated at baseline and at 3, 6, and 12 months. Cognitive function was assessed at baseline. Multiple mediation analyses were conducted with baseline data, end point data, and changes-in-scale scores between baseline and the end point, respectively. RESULTS: At baseline and at 12 months, only psychotic symptoms mediated the effect of insight on personal-social functioning. For changes-in scale scores over the 12-month follow-up, in patients receiving treatment with medication alone, the effect of improved insight on improved personal-social function was mediated by psychotic symptoms only; in patients receiving a combined treatment, the effect of improved insight on improved personal-social functioning was mediated by both psychotic symptoms and attitudes toward medication, independently. CONCLUSIONS: The link between insight and personal social functions is mainly mediated by psychotic symptoms. Psychosocial intervention improves the predicting effect of insight on personal-social function by improving both the attitude toward medication and psychotic symptoms independently.

AB - BACKGROUND: The classic animal model of Parkinson's disease (PD) using neurotoxin can only simulate fixed stages of the disease by causing irreversible damage to the nigrostriatal system. OBJECTIVES: To develop an optogenetic PD model that can modulate the severity of disease by optical stimulation by introducing the halorhodopsin (NpHR) gene into the substantia nigra compacta. METHODS: Fifteen rats received injections of engineered AAV with NpHR-YFP gene into the substantia nigra. They were then subjected to illumination of 590-nm light wavelengths with 3 optical stimulation conditions, i.e., frequency-width: 5 Hz-10 ms (n = 5), 5 Hz 100 ms (n = 5), and 50 Hz-10 ms (n = 5). Eleven rats received 6-hydroxydopamine injections to establish the conventional PD model. RESULTS: The optogenetic models showed characteristic PD manifestations, similar to those of the conventional models; the severity of forelimb akinesia correlated with the total illumination value (frequency * width). The group with a low illumination value (5 Hz-10 ms) was comparable to the conventional partial model whereas the groups with high illumination values (5 Hz-100 ms and 50 Hz-10 ms) were similar to the conventional complete model. CONCLUSIONS: An optogenetic PD model has the advantage of more appropriately representing various PD stages by controlling illumination parameters. PMID- 29444524 TI - Editorial. PMID- 29444529 TI - Endoscopy assistants influence the quality of colonoscopy. AB - BACKGROUND: Colonoscopy performance varies between endoscopists, but little is known about the impact of endoscopy assistants on key performance indicators. We used a large prospective colonoscopy quality database to perform an exploratory study to evaluate differences in selected quality indicators between endoscopy assistants. METHODS: All colonoscopies reported to the Norwegian colonoscopy quality assurance register Gastronet can be used to trace individual endoscopy assistants. We analyzed key quality indicators (cecum intubation rate, polyp detection rate, colonoscopies rated as severely painful, colonoscopies with sedation or analgesia, and satisfaction with information) for colonoscopies performed between 1 January 2013 and 31 December 2014. Differences between individual assistants were analyzed by fitting multivariable logistic regression models, with the best performing assistant at each participating hospital as reference. All models were adjusted for the endoscopist. RESULTS: 63 endoscopy assistants from 12 hospitals assisted in 15 365 colonoscopies. Compared with their top performing peers from the same hospital, one assistant was associated with cecum intubation failure, four with poor polyp detection, nine with painful colonoscopy, 16 with administration of sedation or analgesics during colonoscopy, and three with patient dissatisfaction about information given relating to the colonoscopy. The number of procedures during the study period or lifetime experience as an endoscopy assistant were not associated with any quality indicator. CONCLUSION: In this exploratory study, there was little variation on important colonoscopy quality indicators between endoscopy assistants. However, there were differences among assistants that may be clinically important. Endoscopy assistants should be subject to quality surveillance similarly to endoscopists. PMID- 29444530 TI - Morphine Analgesia Pre-PPCI Is Associated with Prothrombotic State, Reduced Spontaneous Reperfusion and Greater Infarct Size. AB - : The emergency management of ST-elevation myocardial infarction (STEMI) involves treatment with dual-antiplatelet therapy (DAPT) and primary percutaneous coronary intervention (PPCI). Pain is generally treated with opiates, which may delay gastric transit and reduce DAPT absorption. We sought to assess the effect of morphine on reperfusion, infarct size and thrombotic status in 300 patients presenting for PPCI. Morphine was given in a non-randomized fashion as required by emergency teams en route to the heart attack centre. All patients received DAPT and PPCI according to standard care, with optional glycoprotein IIb/IIIa inhibitor (GPI) use. Patients were assessed for ST-segment resolution, coronary flow, thrombotic status and peak troponin. Patients receiving morphine (n = 218; 72.7%) experienced less spontaneous ST-segment resolution pre-PPCI, lower rate of TIMI 2/3 flow in the infarct-related artery pre-PPCI and higher peak troponin level post-PPCI (median [interquartile range]; 1,906 [1,002-4,398] vs. 1,268 [249 2,920] ng/L; p = 0.016) than those who did not. Patients receiving morphine exhibited significantly enhanced platelet reactivity and impaired endogenous fibrinolysis on arrival, compared with no-morphine patients. Morphine administration was an independent predictor of failure of spontaneous ST-segment resolution after adjustment for other variables (odds ratio: 0.26; confidence interval: 0.08-0.84; p = 0.025). Among patients receiving GPI, there was no difference in pre-PPCI flow or peak troponin according to morphine use, suggesting that the adverse effects of morphine relate to delayed DAPT absorption, which may be overcome by GPI. Our hypothesis-generating data suggest that morphine use in STEMI is associated with enhanced platelet reactivity, reduced spontaneous myocardial reperfusion (pre-PPCI) and larger infarct size, and these adverse effects may be influenced by GPI use.

PMID- 29444532 TI - [An across-scales analysis of the voice self-concept questionnaire (FESS)]. AB - BACKGROUND: The questionnaire for the assessment of the voice selfconcept (FESS) contains three sub-scales indicating the personal relation with the own voice. The scales address the relationship with one's own voice, the awareness of the use of one's own voice, and the perception of the connection between voice and emotional changes. A comprehensive approach across the three scales supporting a simplified interpretation of the results was still missing. MATERIAL AND METHOD: The FESS questionnaire was used in a sample of 536 German teachers. With a discrimination analysis, commonalities in the scale characteristics were investigated. For a comparative validation with voice health and psychological and physiological wellbeing, the Voice Handicap Index (VHI), the questionnaire for Work-related Behavior and Experience Patterns (AVEM), and the questionnaire for Health-related Quality of Life (SF-12) were additionally collected. RESULTS: The analysis provided four different groups of voice self-concept: group 1 with healthy values in the voice self-concept and wellbeing scales, group 2 with a low voice self-concept and mean wellbeing values, group 3 with a high awareness of the voice use and mean wellbeing values and group 4 with low values in all scales. CONCLUSION: The results show that a combined approach across all scales of the questionnaire for the assessment of the voice self-concept enables a more detailed interpretation of the characteristics in the voice self-concept. The presented groups provide an applicable use supporting medical diagnoses. PMID- 29444534 TI - SMFM 2018: Meeting highlights-Thursday (Podcast). PMID- 29444533 TI - Relationship between Blood Glucose Fluctuation and Brain Damage in the Hypoglycemia Neonates. AB - OBJECTIVE: To investigate the relationship between blood glucose fluctuation and brain damage in the hypoglycemia neonates. STUDY DESIGN: A retrospective study including all neonates hospitalized due to hypoglycemia from September 2013 to August 2016 was performed. All the 58 hypoglycemia infants were divided into two groups-the brain-damaged group and the nonbrain-damaged group, according to head magnetic resonance imaging and/or amplitude-integrated electroencephalogram. Relationship between glucose variability and brain damage and whether these variation indexes could act as early indicators for hypoglycemic brain damage were investigated. RESULTS: Of the 13 brain-damaged cases, the lowest blood glucose (LBG) level was lower, while duration of hypoglycemia was longer compared with the 45 nonbrain-damaged cases (p < 0.001). The largest amplitude of glycemic excursions, standard deviation of blood glucose, and mean amplitude of glycemic excursions (MAGE) of the brain-damaged group were higher (p < 0.001). Under receiver-operating characteristic curve, values of area under the curve of MAGE were 0.892, duration of hypoglycemia was 0.921, and LBG was 0.109 (p < 0.0001). CONCLUSION: Brain damage of the hypoglycemia neonates relates not only with LBG and duration of hypoglycemia but also with the blood glucose variation indexes; MAGE and duration of hypoglycemia could act as predictors for brain damage. PMID- 29444535 TI - Neonatal Onset of Epilepsy of Infancy with Migrating Focal Seizures Associated with a Novel GABRB3 Variant in Monozygotic Twins. AB - BACKGROUND: Recently, a study providing insight into GABRB3 mutational spectrum was published (Moller et al 2017). The authors report considerable pleiotropy even for single mutations and were not able to identify any genotype-phenotype correlations. METHODS: The proband (twin B) was referred for massively parallel sequencing of epilepsy-related gene panel because of hypotonia and neonatal seizures. The revealed variant was confirmed with Sanger sequencing in the proband and the twin A, and both parents were tested for the presence of the variant. RESULTS: We report a case of epilepsy of infancy with migrating focal seizures (EIMFS) of neonatal onset in monozygotic twins with a de novo novel GABRB3 variant p.Thr281Ala. The variant has a uniform presentation on an identical genomic background. In addition, early seizure-onset epilepsy associated with GABRB3 mutation has been until now described only for the p.Leu256Gln variant in the GABRB3 (Moller et al 2017, Myers et al 2016) located in the transmembrane domain just as the p.Thr281Ala variant described here. CONCLUSION: De novo GABRB3 mutations may cause neonatal-onset EIMFS with early onset hypotonia, respiratory distress, and severe developmental delay. PMID- 29444536 TI - Optimizing the User Experience: Identifying Opportunities to Improve Use of an Inpatient Portal. AB - BACKGROUND: Patient portals specifically designed for the inpatient setting have significant potential to improve patient care. However, little is known about how the users of this technology, the patients, may interact with the inpatient portals. As a result, hospitals have limited ability to design approaches that support patient use of the portal. OBJECTIVES: This study aims to evaluate the user experience associated with an inpatient portal. METHODS: We used a Think Aloud protocol to study user interactions with a commercially available inpatient portal-MyChart Bedside (MCB). Study participants included 19 English-speaking adults over the age of 18 years. In one-on-one sessions, participants narrated their experience using the MCB application and completing eight specific tasks. Recordings were transcribed and coded into three dimensions of the user experience: physical, cognitive, and sociobehavioral. RESULTS: Our analysis of the physical experience highlighted the navigational errors and technical challenges associated with the use of MCB. We also found that issues associated with the cognitive experience included comprehension problems that spurred anxiety and uncertainty. Analysis of the sociobehavioral experience suggested that users have different learning styles and preferences for learning including self-guided, handouts, and in-person training. CONCLUSION: Inpatient portals may be an effective tool to improve the patient experience in the hospital. Moreover, making this technology available to inpatients may help to foster ongoing use of technology across the care continuum. However, deriving the benefits from the technology requires appropriate support. We identified multiple opportunities for hospital management to intervene. In particular, teaching patients to use the application by making a variety of instructional materials available could help to reduce several identified barriers to use. Additionally, hospitals should be prepared to manage patient anxiety and increased questioning arising from the availability of information in the inpatient portal application. PMID- 29444537 TI - A Novel Patient Recruitment Strategy: Patient Selection Directly from the Community through Linkage to Clinical Data. AB - OBJECTIVE: This article presents and describes our methods in developing a novel strategy for recruitment of underrepresented, community-based participants, for pragmatic research studies leveraging routinely collected electronic health record (EHR) data. METHODS: We designed a new approach for recruiting eligible patients from the community, while also leveraging affiliated health systems to extract clinical data for community participants. The strategy involves methods for data collection, linkage, and tracking. In this workflow, potential participants are identified in the community and surveyed regarding eligibility. These data are then encrypted and deidentified via a hashing algorithm for linkage of the community participant back to a record at a clinical site. The linkage allows for eligibility verification and automated follow-up. Longitudinal data are collected by querying the EHR data and surveying the community participant directly. We discuss this strategy within the context of two national research projects, a clinical trial and an observational cohort study. CONCLUSION: The community-based recruitment strategy is a novel, low-touch, clinical trial enrollment method to engage a diverse set of participants. Direct outreach to community participants, while utilizing EHR data for clinical information and follow-up, allows for efficient recruitment and follow-up strategies. This new strategy for recruitment links data reported from community participants to clinical data in the EHR and allows for eligibility verification and automated follow-up. The workflow has the potential to improve recruitment efficiency and engage traditionally underrepresented individuals in research. PMID- 29444538 TI - [Effects of judo-specific resistance training on kinetic and electromyographic parameters of pulling exercises in judo athletes]. AB - BACKGROUND: In judo, rapid force production during pulling movements is an important component of athletic performance, which is why this capacity needs to be specifically exercised in judo. This study aimed at examining the effects of a judo-specific resistance training program using a judo ergometer system (PTJ) versus a traditional resistance training regime using a partner (PTP) on kinetics and muscle activity of judo-specific pulling exercises. METHOD: Twenty-four male judo athletes (age: 22 +/- 4 years, training experience: 15 +/- 3 years) were randomly assigned to two groups. In a crossover design, the first group completed a 4-week PTJ followed by four weeks of PTP (each with three sessions per week). The second group conducted PTP prior to PTJ. PTJ and PTP were completed in addition to regular training. Before, 4 weeks and 8 weeks after training, tests were conducted to assess judo-specific pulling kinetics (i. e. maximal force, rate of force development [RFD], mechanical work) and electromyographic (EMG) shoulder/trunk muscle activity (i. e. biceps brachii muscle, deltoid muscle, trapezius muscle, erector spinae muscle) during pulling movements using a judo ergometer as well as unspecific strength tests (i. e. bench-pull, pull-ups). RESULTS: The statistical analysis revealed that in both groups ergometer pulling kinetics (p <.05, 0.83 <=d<= 1.77) and EMG activity (p <.05; 1.07 <=d<= 2.25) were significantly enhanced following 8 weeks of training. In addition, significantly larger gains in RFD, mechanical work, and EMG activity (i. e. deltoid muscle, erector spinae muscle, trapezius muscle) were found following PTJ compared to PTP (p <.05, 1.25 <=d<= 2.79). No significant enhancements were observed with the unspecific strength tests. CONCLUSION: Our findings indicate that PTJ is superior to PTP regarding training-induced improvements in force production and muscle activity during judo-specific pulling exercises. Performance enhancements may partly be attributed to neural adaptations. No transfer effects on unspecific strength tests were detected following PTJ and PTP. PMID- 29444539 TI - Relationships between maximal strength of lower limb, anthropometric characteristics and fundamental explosive performance in handball players. AB - BACKGROUND: The purpose of this study was to examine relationships between lower body muscular strength, anthropometric characteristics and several measures of explosive performance in elite team-handball players. METHODS: 22 male elite team-handball players (age: 19.1 +/- 1.7 years) were studied during the competitive season. Standard anthropometric and body composition measures included body mass index, lower limb and thigh muscle volume, and body fat percentage. Maximal leg strength was determined by a one-repetition maximum (1 RM) half back-squat. Vertical jump performance was assessed using a squat jump (SJ) and a counter movement jump (CMJ). Repeated shuttle-sprint ability (RSA) was tested by 6 (2 * 15 m) shuttle sprints with 20 s of active recovery intervals. The best time in a single shuttle sprint (30m; RSAbest), fastest total time (RSATT) and RSA test performance decrement (RSAdec) were recorded. Agility was measured using a modified T-half test (MAT). Throwing velocities of jump shooting and 3-step throwing were recorded by digital video camera. RESULTS: The explained variance of 1-RM half-back-squats ranged from 0.2 % (RSA% Fatigue Index) to 70.1 % (CMJ). Four out of 8 variables (RSA Best Time, CMJ, SJ, throwing velocity of jump shoot) demonstrated an r2 > 0.5. Jump performances seemed closely related to 1-RM half-back-squats. Furthermore, 1-RM half-back-squats were positively correlated with leg and thigh muscle volumes (r = 0.652, r = 0.768). CONCLUSION: The anthropometric characteristics and some physical performance tests are closely related to the maximal strength performance of handball players. Coaches should focus on maximal strength training programs for the lower limbs when seeking improvements in the throwing velocity and jump performance of handball players. PMID- 29444540 TI - The Impact of Computed Tomography on Decision Making in Tibial Plateau Fractures. AB - Schatzker introduced one of the most used classification systems for tibial plateau fractures, based on plain radiographs. Computed tomography brought to attention the importance of coronal plane-oriented fractures. The goal of our study was to determine if the addition of computed tomography would affect the decision making of surgeons who usually use the Schatzker classification to assess tibial plateau fractures. Image studies of 70 patients who sustained tibial plateau fractures were uploaded to a dedicated homepage. Every patient was linked to a folder which contained two radiographic projections (anteroposterior and lateral), three interactive videos of computed tomography (axial, sagittal, and coronal), and eight pictures depicting tridimensional reconstructions of the tibial plateau. Ten attending orthopaedic surgeons, who were blinded to the cases, were granted access to the homepage and assessed each set of images in two different rounds, separated to each other by an interval of 2 weeks. Each case was evaluated in three steps, where surgeons had access, respectively to radiographs, two-dimensional videos of computed tomography, and three-dimensional reconstruction images. After every step, surgeons were asked to present how would they classify the case using the Schatzker system and which surgical approaches would be appropriate. We evaluated the inter- and intraobserver reliability of the Schatzker classification using the Kappa concordance coefficient, as well as the impact of computed tomography in the decision making regarding the surgical approach for each case, by using the chi-square test and likelihood ratio. The interobserver concordance kappa coefficients after each assessment step were, respectively, 0.58, 0.62, and 0.64. For the intraobserver analysis, the coefficients were, respectively, 0.76, 0.75, and 0.78. Computed tomography changed the surgical approach selection for the types II, V, and VI of Schatzker (p < 0.01). The addition of computed tomography scans to plain radiographs improved the interobserver reliability of Schatzker classification. Computed tomography had a statistically significant impact in the selection of surgical approaches for the lateral tibial plateau. PMID- 29444541 TI - Functional Regions of the Medial Patellofemoral Ligament. AB - The purpose of this study was to explore the anatomy and discuss functional regions of the medial patellofemoral ligament (MPFL). Twelve fresh-frozen knees specimens were dissected. All medial surfaces of knees were intact and did not have indication of injury. General feature of the MPFL were observed. All anatomical landmarks were carefully identified and marked. The length of the two functional regions were conducted and recorded. All data were obtained, described, and analyzed in the form of mean +/- standard deviation. The MPFL was found in all specimens we dissected. Closed to the patellar insertion, it adheres to the deep surface of the vastus medialis obliquus (VMO). Due to the VMO, the MPFL is divided into two functional regions: overlap region and nonoverlap region. Anatomically, the overlap region and nonoverlap region of 25.43 +/- 2.0 and 44.85 +/- 3.04 mm, the width of VMO insertion is 13.94 +/- 2.03 mm, and the width of patellar insertion is 22.91 +/- 3.46 mm. We divide the MPFL into two anatomical functional regions, demarcated by the meshing points of fibers between the MPFL and VMO: overlap region and nonoverlap region. This finding provides the theoretical foundation for the treatment of the MPFL injury and shed lights on the future researches. PMID- 29444542 TI - Kinematically Aligned Total Knee Arthroplasty or Mechanically Aligned Total Knee Arthroplasty. AB - Kinematically aligned total knee arthroplasty (KATKA) was developed to more anatomically align the knee prosthesis to restore the native alignment of the knee and promote physiological kinematics. Even though there are concerns with implant survival, and follow-up at 10 years or more after KATKA has not been reported, there is a negligible incidence of failure of a tibial component at 2 to 9 years. Early clinical results with this technique are encouraging and demonstrate better functional outcomes compared with mechanically aligned TKA (MATKA). The purpose of this study is to perform a systematic review and meta analysis of the literature to determine whether there are any clinical differences between KATKA and MATKA. The authors conducted a systematic review of the English literature. Five randomized controlled trials (RCTs) which compared clinical outcomes of KATKA and MATKA were finally included. Four RCTs used patient-specific instrument, and one RCT used navigation. Data were extracted and meta-analysis was conducted. KATKA patients had better outcomes: Mean difference between KATKA and MATKA and p-value are presented in brackets after each variable: the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) (-12.5; p < 0.0001), Oxford Knee Score (OKS) (2.3; p = 0.030), combined Knee Society Score (C-KSS) (13.1; p < 0.0001), Knee Function Score (KFS) (6.4; p = 0.0070), and postoperative range of motion (ROM) (4.1 degrees ; p = 0.0010). There was no significant difference concerning the complication rates which needed reoperations or revision surgery (odds ratio, 1.01; p = 0.99). KATKA components had a more femoral valgus (-1.8 degrees ; p < 0.0001), more tibial varus (1.2 degrees ; p = 0.0001), and more tibial slope (1.2 degrees ; p = 0.0001), all being statistically significantly different. Better clinical outcomes were obtained in KATKA and component placement in KATKA is significantly different from that in MATKA. There was no increase of patients with poor clinical results due to implant position especially for varus placement of tibial component. This systematic review of five RCTs suggests that KATKA is of potential alternative method to MATKA since the risk of revision for tibial loosening is negligible compared with MATKA for the same follow-up period. PMID- 29444543 TI - Posterolateral Corner Reconstruction Using the Anatomical Two-Tailed Graft Technique: Clinical Outcomes in the Multiligament Injured Knee. AB - Injury to the posterolateral corner (PLC) of the knee can lead to both varus and rotational instability. Multiple PLC reconstruction techniques have been described, including one-tailed graft (fibula-based constructs) or two-tailed graft (combined fibula- and tibia-based constructs). The purpose of our study was to evaluate the clinical outcomes of anatomical two-tailed graft reconstruction of the PLC in the setting of multiligament knee injuries (MKLIs) with grade III varus instability. Patients were identified through a prospective MLKI database between 2004 and 2013. Patients who received fibular collateral ligament and PLC reconstructions using a two-tailed graft and had a minimum follow-up of 2 years were included. Patients were assessed for clinical laxity grade, range of motion, and functional outcomes using Lysholm and International Knee Documentation Committee (IKDC) scores. Twenty patients (16 male, 4 female) with a mean age of 30.7 (range: 16-52) and a mean follow-up of 52.2 months (range: 24-93 months) were included. Knee dislocation (KD) grades included: 4 KD-1, 10 KD 3-L, 5 KD-4, and 1 KD-5. No patients had isolated PLC injuries. Mean IKDC and Lysholm score were 73.1 +/- 25.8 and 78 +/- 26, respectively. Mean range of motion was -1.1 to 122.8. In full extension, two patients (10%) had grade 1 laxity to varus stress. In 30 degrees of knee flexion, five (25%) patients had grade 1 laxity, and two (10%) had grade 2 laxity. Anatomical two-tailed PLC reconstruction can reliably restore varus stability when performed on patients with MLKIs and type C posterolateral instability with hyperextension external rotation recurvatum deformity. Satisfactory functional outcome scores were achieved in the majority of patients. This study supports the use of an anatomical two-tailed PLC reconstruction in the multiligament injured knee. The level of evidence is IV, case series. PMID- 29444544 TI - Uridine 5'diphospho-glucuronosyltransferase 1A expression as an independent prognosticator in urothelial carcinoma of the upper urinary tract. AB - OBJECTIVE: To determine the expression status of uridine 5'diphospho glucuronosyltransferase 1A, a major phase II drug metabolism enzyme, in upper urinary tract urothelial carcinoma, as well as to assess its prognostic significance. METHODS: We immunohistochemically stained for uridine 5'diphospho glucuronosyltransferase 1A in tissue microarray consisting of 99 upper urinary tract urothelial carcinoma samples and paired non-neoplastic urothelial tissues. We also assessed the effect of uridine 5'diphospho-glucuronosyltransferase 1A knockdown on urothelial cancer cell growth. RESULTS: Uridine 5'diphospho glucuronosyltransferase 1A was positive in 92.9% (27.3% weak [1+], 37.4% moderate [2+], 28.3% strong [3+]) of tumors, which was significantly (P < 0.001) lower than in benign urothelial tissues (98.8%; 3.5% 1+, 18.8% 2+, 76.4% 3+). All 37 (100%) non-muscle-invasive versus 55 (88.7%) of 62 muscle-invasive tumors (P = 0.043) were immunoreactive for uridine 5'diphospho-glucuronosyltransferase 1A. The rates of moderate-to-strong uridine 5'diphospho-glucuronosyltransferase 1A expression and its positivity were also strongly associated with the absence of concomitant carcinoma in situ (P = 0.034) and lymphovascular invasion (P = 0.016), respectively. However, there were no statistically significant associations between uridine 5'diphospho-glucuronosyltransferase 1A expression and tumor grade or pN/M status. Uridine 5'diphospho-glucuronosyltransferase 1A loss in M0 tumors was strongly associated with lower progression-free survival (P < 0.001) and cancer-specific survival (P < 0.001) rates. Multivariate analysis further identified a strong correlation of uridine 5'diphospho glucuronosyltransferase 1A positivity with reduced cancer-specific mortality (hazard ratio 0.28, P = 0.018). Meanwhile, uridine 5'diphospho glucuronosyltransferase 1A knockdown in urothelial cancer cells resulted in significant increases in their viability and migration. CONCLUSIONS: These results suggest a preventive role of uridine 5'diphospho-glucuronosyltransferase 1A signals in the development and progression of upper urinary tract urothelial carcinoma. Loss of uridine 5'diphospho-glucuronosyltransferase 1A expression might serve as an independent predictor of poor prognosis in patients with upper urinary tract urothelial carcinoma. PMID- 29444545 TI - Bretschneider and del Nido solutions: Are they safe for coronary artery bypass grafting? If so, how should we use them? AB - A variety of cardioplegic solutions are being used widely today to arrest the heart during coronary artery bypass grafting (CABG) and other cardiac operations. To minimize interruptions during the surgery for intermittent dosing of the cardioplegia and to facilitate less invasive cardiac procedures, single-shot solutions, including Bretschneider and del Nido solutions, have been introduced. This review examines the evidence regarding the safety and efficacy of Bretschneider and del Nido cardioplegia during CABG. The findings support their use in routine low-risk CABG, but finds insufficient evidence to support their safety in high-risk surgeries. PMID- 29444546 TI - Simultaneous small-sample comparisons in longitudinal or multi-endpoint trials using multiple marginal models. AB - Simultaneous inference in longitudinal, repeated-measures, and multi-endpoint designs can be onerous, especially when trying to find a reasonable joint model from which the interesting effects and covariances are estimated. A novel statistical approach known as multiple marginal models greatly simplifies the modelling process: the core idea is to "marginalise" the problem and fit multiple small models to different portions of the data, and then estimate the overall covariance matrix in a subsequent, separate step. Using these estimates guarantees strong control of the family-wise error rate, however only asymptotically. In this paper, we show how to make the approach also applicable to small-sample data problems. Specifically, we discuss the computation of adjusted P values and simultaneous confidence bounds for comparisons of randomised treatment groups as well as for levels of a nonrandomised factor such as multiple endpoints, repeated measures, or a series of points in time or space. We illustrate the practical use of the method with a data example. PMID- 29444547 TI - Laparoscopic surgery with urinary tract reconstruction and bowel endometriosis resection for deep infiltrating endometriosis. AB - Deep infiltrating endometriosis (DIE) is the most severe form of endometriosis. It causes chronic pelvic pain, severe dysmenorrhea, deep dyspareunia, dyschezia, and dysuria, markedly impairing the quality of life of women of reproductive age. A number of randomized controlled trials on surgical and medical treatments to reduce the pain associated with endometriosis have been reported, but few have focused on this in DIE. DIE causes not only pain but also functional invasion to the urinary organs and bowel, such as hydronephrosis and bowel stenosis. In addition to DIE resection, surgical treatment involves adhesion separation as well as resection and reconstruction of the urinary organs and bowel; high-level skills are required. The severity of DIE should be evaluated preoperatively as accurately as possible. Using ENZIAN in conjunction with the AFS (The revised American Fertility Society classification of endometriosis) classification makes a more detailed assessment of DIE possible. The operative procedures used for laparoscopic resection of urinary DIE and reconstruction of the urinary organs are chosen based on the type of lesion (intrinsic/extrinsic) and length of stenosis. In addition to ureteroneocystostomy, the psoas bladder hitch and Boari bladder flap procedures are applied when necessary to extend the urinary tract. Bowel resection for bowel endometriosis is classified into classic segmental resection and conservative approaches (shaving/discoid). When these procedures are employed, it is advisable to work in consultation with urologists and gastroenterologists and to inform the patients of the associated risks and outcomes. Furthermore, postoperative medication is essential because it is difficult to conduct repeated surgeries. PMID- 29444548 TI - Tribute to Professor Malcolm Bourne. PMID- 29444549 TI - Body weight change is unpredictable after total thyroidectomy. AB - BACKGROUND: There is a common perception that total thyroidectomy causes weight gain beyond expected age-related changes, even when thyroid replacement therapy induces a euthyroid state. The aim of this study was to determine whether patients who underwent total thyroidectomy for a wide spectrum of conditions experienced weight gain following surgery. METHODS: We retrospectively studied 107 consecutive total thyroidectomy patients treated between January 2013 and June 2014. Medical records were reviewed to determine underlying pathology, thyroid status, use of antithyroid drugs and preoperative weight. Follow-up data were obtained from 79 patients at least 10 months post-operatively to determine current weight, the type of clinician managing thyroid replacement therapy and patient satisfaction with post-thyroidectomy management. RESULTS: The cohort was 73% female, with a mean age of 55.8 +/- 15.7 years and a mean preoperative weight of 78.8 +/- 17.5 kg. Commonest pathologies were multinodular goitre, Graves' disease, thyroid cancer and Hashimoto's thyroiditis. Preoperatively, 63.2% of patients were hyperthyroid. Mean weight change at follow-up was a non-significant increase of 0.06 +/- 6.9 kg (P = 0.094). Weight change was not significant regardless of preoperative thyroid function status. This study did not demonstrate any significant differences in clinical characteristics (including post-operative thyroid-stimulating hormone) between the group with >2% weight gain and those who did not. CONCLUSIONS: This study did not reveal significant weight gain following thyroidectomy for a wide spectrum of pathologies. Specifically, preoperative hyperthyroidism, female gender and use of antithyroid medications do not predict weight gain after thyroid surgery.

AB - OBJECTIVES: To evaluate the use of shear wave elastography in assessment of kidney allograft tubulointerstitial fibrosis. METHODS: Shear wave elastography assessment was carried out by two independent operators in kidney transplant recipients who underwent allograft biopsy for clinical indications (i.e. rising creatinine >15% or proteinuria >1 g/day). Allograft biopsies were interpreted by the same pathologist according to the 2013 Banff Classification. RESULTS: A total of 40 elastography scans were carried out (median creatinine 172.5 MUmol/L [interquartile range 133.8-281.8 MUmol/L]). Median tissue stiffness at the cortex (22.6 kPa [interquartile range 18.8-25.7 kPa] vs 22.3 kPa [interquartile range 19.0-26.5 kPa], P = 0.70) and medulla (15.0 kPa [interquartile range 13.7-18.0 kPa] vs 15.6 kPa [interquartile range 14.4-18.2 kPa]) showed no significant differences between the two observers. Interobserver agreement was satisfactory (intraclass correlation coefficient of the cortex 0.84, 95% CI 0.70-0.92 and intraclass correlation coefficient of the medulla 0.88, 95% CI 0.78-0.94). The areas under the receiver operating characteristic curves for detection of tubulointerstitial fibrosis were estimated to be 0.75 (95% CI 0.61-0.89), 0.85 (95% CI 0.75-0.95) and 0.65 (95% CI 0.53-0.78) for cortical, medullary tissue stiffness and serum creatinine, respectively. CONCLUSIONS: Shear wave elastography can be used as a non-invasive tool to evaluate kidney allograft fibrosis with reasonable interobserver agreement and superior test performance to serum creatinine in detecting early tubulointerstitial fibrosis.

AB - BACKGROUND: Lions Outback Vision has run a state-wide teleophthalmology service since 2011. In September 2015 the Australian federal government introduced a Medicare reimbursement for optometry-facilitated teleophthalmology consultations under specific circumstances. This audit demonstrates the first 12 months experience with this scheme. We aim to provide practical insights for others looking to embed a telemedicine program as part of delivering outreach clinical services. METHODS: A 12-month retrospective audit was performed between September 2015 and August 2016, inclusive. A research officer used a specifically designed data extraction tool to record information from all teleophthalmology consultations performed in the time period. The primary outcome was the diagnosis at the end of the teleophthalmology consultation. Secondary outcome measures included the number of teleconsultations, cataract surgery rate, remoteness area of patients referred and imaging accompanying the referral. RESULTS: In the 12 month period, 709 patients were referred resulting in 683 teleophthalmology teleconsultations. Cataract was the most frequent diagnosis (n = 287, 42.7 per cent), followed by glaucoma (n = 77, 11 per cent), age-related macular degeneration (n = 30, 4.4 per cent) and diabetic retinopathy (n = 26, 3.8 per cent). Of those who had teleconsultations, 98.6 per cent were from Outer Regional, Remote or Very Remote Australia. One or more accompanying images or investigations were part of 349 (49 per cent) teleconsultations, most commonly optical coherence tomography (215, 30 per cent) and fundus photography (148, 21 per cent). Face-to-face consultations were undertaken at an outreach clinic in 23 (3.4 per cent) cases, to determine the diagnosis. There were no statistically significant factors associated with attendance at teleophthalmology consultation, or for successfully undergoing cataract surgery. CONCLUSION: Teleophthalmology is a valuable adjunct to regional outreach ophthalmology services, providing patients with increased access to specialist care for a wide range of ophthalmic conditions, and more efficient access to surgical care.

PMID- 29444553 TI - Evaluation of biomarkers for treatment selection using individual participant data from multiple clinical trials. AB - Biomarkers that predict treatment effects may be used to guide treatment decisions, thus improving patient outcomes. A meta-analysis of individual participant data (IPD) is potentially more powerful than a single-study data analysis in evaluating markers for treatment selection. Our study was motivated by the IPD that were collected from 2 randomized controlled trials of hypertension and preeclampsia among pregnant women to evaluate the effect of labor induction over expectant management of the pregnancy in preventing progression to severe maternal disease. The existing literature on statistical methods for biomarker evaluation in IPD meta-analysis have evaluated a marker's performance in terms of its ability to predict risk of disease outcome, which do not directly apply to the treatment selection problem. In this study, we propose a statistical framework for evaluating a marker for treatment selection given IPD from a small number of individual clinical trials. We derive marker-based treatment rules by minimizing the average expected outcome across studies. The application of the proposed methods to the IPD from 2 studies in women with hypertension in pregnancy is presented.

AB - INTRODUCTION: The safety and efficacy of transvenous embolization of brain arteriovenous malformations (AVM) remains relatively poorly understood. We performed a systematic review of the literature to determine outcomes of transvenous embolization of brain AVMs. EVIDENCE ACQUISITION: Data Sources include Ovid MEDLINE, Ovid EMBASE and the Web of Science. All case series with >=4 patients receiving transvenous embolization of brain AVMs published through September 2017 were included. EVIDENCE SYNTHESIS: A total of 8 series with 66 patients were included. All-cause mortality rate was 6.0% (95%CI=0.0%-11.0%). There were no cases of treatment related mortality. Overall good functional outcome rates were 89.0% (95%CI=82.0%-96.0%). Complete occlusion rates were 96.0% (95%CI=91.0%-100.0%). Technical complications rates were 8.0% (95%CI=2.0%-14.0%). Additional treatment rates were 6.0% (95%CI=0.0%-11.0%). CONCLUSIONS: Patients receiving transvenous embolization of AVMs experience good long- term clinical outcomes in nearly 90% of highly selected cases. Further large case series are needed to confirm the result. PMID- 29444557 TI - Limits of the endoscopic transnasal transtubercular approach. AB - INTRODUCTION: The endoscopic transnasal trans-sphenoidal transtubercular approach has become a standard alternative approach to neurosurgical transcranial routes for lesions of the anterior skull base in particular pathologies of the anterior tubercle, sphenoid plane, and midline lesions up to the interpeduncular cistern. For both the endoscopic and the transcranial approach indications must strictly be evaluated and tailored to the patients' morphology and condition. The purpose of this review was to evaluate the evidence in literature of the limitations of the endoscopic transtubercular approach. EVIDENCE ACQUISITION: A PubMed/Medline search was conducted in January 2018 entering following keywords. Upon initial screening 7 papers were included in this review. There are several other papers describing the endoscopic transtubercular approach (ETTA). We tried to list the limitation factors according to the actual existing literature as cited. EVIDENCE SYNTHESIS: The main limiting factors are laterally extending lesions in relation to the optic canal and vascular encasement and/or unfavorable tumor tissue consistency. CONCLUSIONS: The ETTA is considered as a high level transnasal endoscopic extended skull base approach and requires excellent training, skills and experience. PMID- 29444558 TI - Limitations of the endoscopic endonasal transcribriform approach. AB - The endoscopic endonasal transcribriform approach (EETA) has become a useful strategy in the treatment of various anterior skull base pathologies, including meningoencephaloceles, olfactory groove meningiomas, schwannomas, esthesioneuroblastomas, and other sinonasal malignancies. However, not all pathologies are optimally treated through this approach due to tumor size, extent of the lesion, vascular involvement, and the presence of intact olfaction. One must be prepared to use a transcranial approach if the EETA is not favorable. In some patients, a combined approach (transcranial-EETA) may be needed in appropriate cases. Therefore, patient selection is paramount for achieving a successful result with avoidance of complications. For certain tumors, the limitations of the EETA may result in lower rates of gross-total resection, higher rates of cerebrospinal fluid leakage, postoperative impairment of olfaction, and higher complication rates. In this paper, we discuss the limitations of the EETA when considering approach selection to treat anterior skull base lesions. PMID- 29444559 TI - Concurrent Alzheimer's pathology in patients with clinical normal pressure hydrocephalus. AB - BACKGROUND: Patients with normal pressure hydrocephalus (NPH) and Alzheimer's dementia (AD) can often present with similar symptoms. NPH remains a clinical diagnosis and there are reported shared underlying dynamics of cerebrospinal fluid (CSF) flow and histopathology with patients with biopsy-proven AD. METHODS: This is a review on the histopathology and cerebrospinal fluid dynamics of both NPH and AD. In a prior study at the University of Virginia, the authors reviewed patients over a 15 year period who were shunted for a preoperative diagnosis of NPH. Of these patients, 74% received high volume lumbar puncture and at the time of surgery, 159 total biopsies were performed on 113 patients with 46 repeat biopsies. The results of high-volume lumbar punctures, cortical brain biopsies, and clinical outcomes were compared between patients with NPH and those found to have Alzheimer's pathology. RESULTS: As many as 24% of patients with clinical diagnosis of NPH may demonstrate concomitant Alzheimer's dementia based on histopathological biopsy performed at the time of shunt placement. In patients in whom a CSF shunt was placed and biopsy obtained, 19% of patients demonstrated histopathologiy consistent with CERAD diagnosis of AD. However, more than half (53%) of all patients demonstrated some degree of neuritic plaque development, while 14% and 9% demonstrated evidence of neurofibrillary tangles and amyloid angiopathy, respectively. The improved clinical response seen with HVLP was not sustained following shunt insertion; 45% of NPH patients with positive response to HVLP improved following shunt placement compared to just 18% of concurrent NPH and AD patients (p = 0.0136). CONCLUSIONS: There is a high prevalence of AD in patients who are shunted for a clinical diagnosis of NPH. The presenting symptoms of NPH and AD may be very similar and the significant difference in histopathology is what separates the two disease processes. There may be temporary relief with restoring cerebrospinal fluid flow but the presence of underlying neurodegenerative changes more directly correlates with long-term outcomes. There may also be a direct correlation between altered CSF dynamics in both the metabolic clearance and the development of dementia. PMID- 29444560 TI - Cohort studies, trials, and tribulations: systematic review and an evidence-based approach to arteriovenous malformation treatment. AB - INTRODUCTION: There is uncertainty as to the best management of arteriovenous malformations of the brain (bAVM). However, the Spetzler-Martin grade (SMG) has been validated as an effective determinant of surgical risks. We performed a systematic review for the best evidence regarding the management of bAVM for series that incorporate an analysis based upon SMG. EVIDENCE ACQUISITION: Medline, Embase, Scopus and Cochrane databases were searched for series between January 2000 and January 2018, with a minimum of 100 cases and that incorporated SMG stratification. From this primary search, series were selected for analysis that dichotomized outcomes at modified Rankin Scale (mRS) scores between 1 and 2 due to complications of treatment or reported favorable outcome (FO) (i.e. complete occlusion, no neurological deterioration and no post treatment hemorrhage). Case series that used a subset of the population other than SMG or had a prior history of hemorrhage were excluded. The series finally analyzed were explored for outcomes that reported: complications of treatment that led to a new permanent neurological deficit with mRS score >1 (adverse outcome); post treatment hemorrhage; occlusion rate; and FO. A comparison of treatment outcomes was made when more than one modality of treatment (surgery, radiosurgery, embolization or multiple treatment modalities) could be examined with results for specific Spetzler-Ponce class (SPC) A (i.e. SMG I and II), B (i.e. SMG III) or C (i.e. SMG IV and V). EVIDENCE SYNTHESIS: The primary search produced 116 papers. After reviewing each publication and eliminating papers that had patient outcomes duplicated, 11 publications met the criteria for analysis (including: 5 exclusively surgery; 4 exclusively radiosurgery; 1 exclusively endovascular; and, 1 multi-modality). The following outcome comparisons analyzed were significant. For SPC A and B bAVM, there was a significantly higher rate of FO following treatment by surgery (98.6%; 95% CI: 97.5-99.2% and 76.4%; 95% CI: 70.0-81.7%, respectively) than radiosurgery (70.8%; 95% CI: 66.8-74.6% and 61.0%; 95% CI: 56.0-65.8%, respectively)(P<0.01). For SPC A and B bAVM, there were significantly fewer unobliterated bAVM following treatment by surgery (0.5%; 95% CI: 0.2-1.4% and 3.0%; 95% CI: 1.4-5.8%, respectively) than radiosurgery (23.9%; 95% CI: 20.4 27.8% and 30.9%; 95% CI: 27.9-34.0%, respectively) or embolization (7.6%; 95% CI: 4.3-12.9% SPC A) (P<0.01). Adverse outcomes from treatment were significantly higher for surgery (15.6%; 95% CI: 11.8-20.0%) than radiosurgery (3.3%; 95% CI: 2.3-4.8%) for SPC B (P<0.01) but not SPC A bAVM. No analysis of SPC C was possible. CONCLUSIONS: Surgery remains, in general, the best choice for treating SPC A bAVM. For SPC B bAVM the decision as to best treatment should hinge on the likelihood of obliteration by radiosurgery. In cases where obliteration rate is expected to be high, radiosurgery should be the preferred treatment. There is insufficient information to make a recommendation from this analysis with regards the role of embolization for cure. There is no satisfactory standardized treatment for SPC C bAVM and treatment must remain individualized. PMID- 29444561 TI - Committed to be fit. The value of preoperative care in the perioperative medicine era. AB - In the era of perioperative medicine, important advances have been made in the perioperative care of patients, usually within those known as enhanced recovery after surgery (ERAS) protocols. These have led to a decrease in postoperative complications and the duration of hospital stays; however, there is still a lack of preoperative care, which could make perioperative medicine more prominent. Elderly patients, malnourished, anemic and ones with a low physical function before surgery are likely to have sub-optimal recovery from surgery. More importantly, a low functional reserve, together with the inherent physiological stress of surgery, reduces the functional capacity of patients in the postoperative period, meaning that they will not reach their preoperative functional capacity. It is well established that both preoperative malnutrition and anemia worsen surgical results, however, for various reasons, their preoperative optimization is complex. Additionally, both are related to the functional capacity of patients. During the last years, prehabilitation has been incorporated into ERAS protocols. Prehabilitation consists of exercise training and nutritional and psychological support, which increases the physiological reserve before surgical stress. The integration of exercise, adequate nutrition, anemia correction and psycho-social components, with multi-modal optimization in the preoperative period leads to an improvement in the functional capacity of the patients undergoing surgery, with the consequent improvement in terms of outcomes. The present article discusses specific aspects of preoperative care which are not well defined in the ERAS protocols and which represent fundamental shifts in surgical practice, including preoperative nutrition, management of preoperative anemia and prehabilitation. PMID- 29444562 TI - Fluid resuscitation during early sepsis: a need for individualization. AB - The prognosis of septic shock is tightly linked to the earliness of both appropriate antibiotic therapy and early hemodynamic resuscitation. This latter is essentially based on fluid and vasopressors administration. The step-by-step strategy, called "early goal-directed therapy" (EGDT) developed in 2001 and endorsed by the Surviving Sepsis Campaign (SSC) between 2004 and 2016 is no longer recommended. Indeed, recent multicenter randomized clinical trials showed no reduction in all-cause mortality, duration of organ support and in-hospital length of stay with EGDT in comparison with standard care. The most recent SCC guidelines have dropped the original EGDT by deleting the central venous pressure and the central venous oxygen saturation from the recommendations. Dynamic variables of fluid responsiveness are now recommended to be used after an initial fluid infusion of a fixed volume (30 mL/kg) during the first three hours of resuscitation. However, this approach is also questionable due to the lack of individualization at the early and crucial phase of resuscitation. In this review, we propose a more personalized approach for the early and later phases of fluid resuscitation during sepsis.

Multifactorial coagulation defects are discussed and point-of care monitoring is reviewed to guide selection of hemostatic agents when indicated. PMID- 29444564 TI - Bio-inspired Edible Superhydrophobic Interface for Reducing Residual Liquid Food. AB - Significant wastage of residual liquid food, such as milk, yogurt, and honey, in food containers has attracted great attention. In this work, a bio-inspired edible superhydrophobic interface was fabricated using U.S. Food and Drug Administration-approved and edible honeycomb wax, arabic gum, and gelatin by a simple and low-cost method. The bio-inspired edible superhydrophobic interface showed multiscale structures, which were similar to that of a lotus leaf surface. This bio-inspired edible superhydrophobic interface displayed high contact angles for a variety of liquid foods, and the residue of liquid foods could be effectively reduced using the bio-inspired interface. To improve the adhesive force of the superhydrophobic interface, a flexible edible elastic film was fabricated between the interface and substrate material. After repeated folding and flushing for a long time, the interface still maintained excellent superhydrophobic property. The bio-inspired edible superhydrophobic interface showed good biocompatibility, which may have potential applications as a functional packaging interface material.

AB - Small-angle neutron scattering (SANS) was used to examine dilute solutions of a poly(quinoxaline-2,3-diyl) (PQX) with (R)-2-octyloxymethyl side chains in deuterated THF or a mixture of deuterated 1,1,2-TCE and THF (8/2, v/v), in which the PQX adopts pure P- and M-helical structures. The structures of the PQX that were obtained based on the SANS experiments in combination with theoretical calculations suggest that in THF, the chiral side chains of the P-helical PQX are extended, whereas in the 1,1,2-TCE/THF mixture, the side chains of the M-helical PQX are folded. Consequently, P-helical structures should be preferred in good solvents such as THF, which solvate the extended side chains, whereas M-helical structures should be preferred in poor solvents such as 1,1,2-TCE, wherein the side chains adopt shrunken conformations with maximized van der Waals interactions between the side chains. This study thus reveals the first example for fully determined nuanced conformations of the side chains of synthetic polymers in solution based on SANS experiments and theoretical calculations. PMID- 29444566 TI - Chemical Characterization of Novel Natural Products from the Roots of Asian Rice ( Oryza sativa) that Control Adipocyte and Osteoblast Differentiation. AB - Oryza sativa L. is consumed globally as a staple food, and its roots have been used as a Korean and Chinese medical supplement for protection of the stomach and lungs and for amelioration of vomiting and fever. In our continuing search for biologically effective metabolites from Korean natural materials, we found that an EtOH extract of O. sativa root reciprocally regulated adipocyte and osteoblast differentiation. Chemical analysis of the EtOH extract using a bioassay-guided fractionation protocol led to the isolation and determination of two novel lignans, oryzativols A and B, responsible for these regulatory activities. Using 1D and 2D nuclear magnetic resonance spectroscopic analyses, high-resolution mass spectrometry, and circular dichroism analysis, the structures of the novel compounds were elucidated. We examined their effects on the regulation of mesenchymal stem cell differentiation. Treatment with oryzativol A in the human mesenchymal cell line C3H10T1/2 suppressed gene expression of peroxisome proliferator activated receptor gamma, which resulted in a reduction in adipogenesis. Oryzativol A also enhanced the expression of Runx2 and cellular differentiation into osteoblasts in the same mesenchymal stem cell line.

AB - N-Propargyltetramethylpiperidine reacts with a series of trans-alkenyl-B(C6F5)2 compounds to give the substituted alkenyl-bridged frustrated N/B Lewis pairs 5. Their structures and spectroscopic features indicate a pronounced participation of the mesomeric s-trans-iminium/borata-alkene resonance form. The compounds are thought to be formed in a stepwise addition/rearrangement process which is initiated by a trans-1,2-amine/borane FLP addition to the carbon-carbon triple bond to generate a reactive zwitterionic aziridinium/alkenylborate intermediate. Subsequent alkenylborate attack leads to opening of the activated three-membered heterocycle with clean formation of the products 5a-c. Treatment of the propargyl TMP substrate with B(C6F5)3 gave a stable example of such an aziridinium/borate betaine, which was isolated and amply characterized. The products 5a-c are active N/B FLPs. They split dihydrogen heterolytically under mild conditions to give the respective NH+/BH- products 9a-c. These contain Z-configurated core C?C double bonds, which indicates rotational equilibration around the central C-C bond of 5a c during this reaction. Structural and chemical features of the 5c system were analyzed by DFT calculations. PMID- 29444568 TI - Structural Features of Reconstituted Cuticular Wax Films upon Interaction with Nonionic Surfactant C12E6. AB - The interaction of nonionic surfactant hexaethylene glycol monododecyl ether (C12E6) with a reconstituted cuticular wheat wax film has been investigated by spectroscopic ellipsometry and neutron reflection (NR) to help understand the role of the leaf wax barrier during pesticide uptake, focusing on the mimicry of the actions adjuvants impose on the physical integrity and transport of the cuticular wax films against surfactant concentration. As the C12E6 concentration was increased up to the critical micelle concentration (CMC = 0.067 mM), an increasing amount of surfactant mass was deposited onto the wax film. Alongside surface adsorption, C12E6 was also observed to penetrate the wax film, which is evident from the NR measurements using fully protonated and chain-deuterated surfactants. Furthermore, surfactant action upon the model wax film was found to be physically reversible below the CMC, as water rinsing could readily remove the adsorbed surfactant, leaving the wax film in its original state. Above the CMC, the detergency action of the surfactant became dominant, and a significant proportion of the wax film was removed, causing structural damage. The results thus reveal that both water and C12E6 could easily penetrate the wax film throughout the concentration range measured, indicating a clear pathway for the transport of active ingredients while the removal of the wax components above the CMC must have enhanced the transport process. As the partial removal of the wax film could also expose the underlying cutaneous substrate to the environment and undermine the plant's health, this study has a broad implication to the roles of surfactants in crop care.

AB - 2-(1 H-Pyrazol-1-ylcarbonyl)-2 H-azirines were synthesized by in situ trapping of 2 H-azirine-2-carbonyl chlorides, generated by Fe(II)-catalyzed isomerization of 5-chloroisoxazoles, with pyrazoles. According to DFT calculations, the selectivity of nucleophilic substitution at the carbonyl group of 2 H-azirine-2 carbonyl chloride by a pyrazole nucleophile, which is a mixture of two tautomers, is controlled by thermodynamic factors. 2-(1 H-Pyrazol-1-ylcarbonyl)-2 H-azirines are excellent precursors for the preparation of two other pyrazole-nitrogen heterocycle dyads: 5-(1 H-pyrazol-1-yl)oxazoles by photolysis and 1-(1 H-pyrrol-2 ylcarbonyl)-1 H-pyrazoles by a Ni(II)-catalyzed reaction with 1,3-dicarbonyl compounds. 5-(1 H-Pyrazol-1-yl)oxazoles show strong emission in acetonitrile at 360-410 nm with high quantum yields. PMID- 29444570 TI - Pyrethroid Pesticide Exposure and Risk of Primary Ovarian Insufficiency in Chinese Women. AB - Pyrethroids are a class of widely used insecticides. Female animal studies suggested that pyrethroid exposure impaired ovarian function, which resulted in similar symptoms of primary ovarian insufficiency (POI). However, it is still unknown whether this association applies to women. In this case-control study, a total of 172 POI patients and 247 control women were recruited in Zhejiang, China. The urinary concentrations of metabolites of pyrethroids, 3-phenoxybenzoic acid (3-PBA) and 4-fluoro-3-phenoxybenzoic acid (4-F-3-PBA), as well as the serum concentrations of follicle-stimulating hormone (FSH), luteinizing hormone (LH) and anti-Mullerian hormone (AMH) were determined. The associations of pyrethroid metabolites with POI and POI-related hormones were accessed using unconditional logistic regression. Higher urinary levels of 3-PBA were significantly associated with increased risk of POI [adjusted odds ratio (OR) = 2.344, 95% CI: 1.193-4.607 for the highest vs lowest quartile of 3-PBA, p = 0.013]. Stratified analyses showed that each log increase in urinary 3-PBA concentration was significantly associated with an induction in odds of 51.0% being in the highest quartile of FSH and 28.6% being in the highest quartile of LH levels, whereas a 25.9% reduction in odds of being in the highest quartile of AMH levels (All p for trend <0.05). To our knowledge, this is the first case-control study to report an association of pyrethroid exposure with increased risk of POI in women. PMID- 29444571 TI - Factors Affecting Mercury Stable Isotopic Distribution in Piscivorous Fish of the Laurentian Great Lakes. AB - Identifying the sources of methylmercury (MeHg) and tracing the transformations of mercury (Hg) in the aquatic food web are important components of effective strategies for managing current and legacy Hg sources. In our previous work, we measured stable isotopes of Hg (delta202Hg, Delta199Hg, and Delta200Hg) in the Laurentian Great Lakes and estimated source contributions of Hg to bottom sediment. Here, we identify isotopically distinct Hg signatures for Great Lakes trout ( Salvelinus namaycush) and walleye ( Sander vitreus), driven by both food web and water-quality characteristics. Fish contain high values for odd-isotope mass independent fractionation (MIF) with averages ranging from 2.50 (western Lake Erie) to 6.180/00 (Lake Superior) in Delta199Hg. The large range in odd-MIF reflects variability in the depth of the euphotic zone, where Hg is most likely incorporated into the food web. Even-isotope MIF (Delta200Hg), a potential tracer for Hg from precipitation, appears both disconnected from lake sedimentary sources and comparable in fish among the five lakes. We suggest that similar to the open ocean, water-column methylation also occurs in the Great Lakes, possibly transforming recently deposited atmospheric Hg deposition. We conclude that the degree of photochemical processing of Hg is controlled by phytoplankton uptake rather than by dissolved organic carbon quantity among lakes. PMID- 29444572 TI - Unraveling the Role of a Flexible Tetradentate Ligand in the Aerobic Oxidative Carbon-Carbon Bond Formation with Palladium Complexes: A Computational Mechanistic Study. AB - Mechanistic details of the aerobic oxidative coupling of methyl groups by a novel (MeL)PdII(Me)2 complex with the tetradentate ligand, MeL = N, N-dimethyl-2,11 diaza[3.3](2,6)pyridinophane, has been explored by density functional theory calculations. The calculated mechanism sheds light on the role of this ligand's flexibility in several stages of the reaction, especially as the oxidation state of the Pd changes. Ligand flexibility leads to diverse axial coordination modes, and it controls the availability of electrons by modulating the energies of high lying molecular orbitals, particularly those with major d z2 character. Solvent molecules, particularly water, appear essential in the aerobic oxidation of PdII by lowering the energy of the oxygen molecule's unoccupied molecular orbital and stabilizing the PdX-O2 complex. Ligand flexibility and solvent coordination to oxygen are essential to the required spin-crossover for the transformation of high-valent PdX-O2 complexes. A methyl cation pathway has been predicted by our calculations in transmetalation between PdII and PdIV intermediates to be preferred over methyl radical or methyl anion pathways. Combining an axial and equatorial methyl group is preferred in the reductive elimination pathway where roles are played by the ligand's flexibility and the fluxionality of trimethyl groups.

PMID- 29444573 TI - Optical Properties of Dissolved Organic Matter and Their Relation to Mercury Concentrations in Water and Biota Across a Remote Freshwater Drainage Basin. AB - Dissolved organic matter (DOM) includes an array of carbon-based compounds that vary in size and structure and have complex interactions with mercury (Hg) cycling in aquatic systems. While many studies have examined the relationship between dissolved organic carbon concentrations ([DOC]) and methyl Hg bioaccumulation, few studies have considered the effects of DOM composition (e.g., protein-content, aromaticity). The goal of this study was to explore the relationships between total and methyl [Hg] in water, invertebrates, and fish and optically derived measures of DOM composition from 47 lake and river sites across a boreal watershed. Results showed higher aqueous total [Hg] in systems with more aromatic DOM and higher [DOC], potentially due to enhanced transport from upstream or riparian areas. Methyl [Hg] in biota were all positively related to the amount of microbial-based DOM and, in some cases, to the proportions of labile and protein-like DOM. These results suggest that increased Hg bioaccumulation is related to the availability of labile DOM, potentially due to enhanced Hg methylation. DOM composition explained 68% and 54% more variability in [Hg] in surface waters and large-bodied fish, respectively, than [DOC] alone. These results show that optical measures of DOM characteristics are a valuable tool for understanding DOM-Hg biogeochemistry.

AB - The study presents an overview of the most common radiography and CT-based classifications of posterior malleolar fractures in ankle fracture-dislocations. Their analysis has shown that posterior malleolar fractures largely vary in size and shape. Evaluation of fractures by plain radiographs is inadequate. A detailed assessment of the fragment shape and course of fracture lines requires CT examination in all three projections, followed by 3D CT reconstructions.Key words: ankle fracture - dislocations trimalleolar fractures posterior malleolar fractures classification. PMID- 29444576 TI - [Fractures of the fifth metatarsal base]. AB - Fractures of the fifth metatarsal base are among the most common fractures of the foot. They are typically caused by indirect violence during sports activities. This region is also a site where stress fractures occur frequently. Diagnosis is based on the patients medical history, clinical examination and imaging methods. The fundamental imaging method is radiography of the foot in three views. MRI is used primarily for early diagnosis of stress fractures. CT examination is beneficial mainly in complex foot injuries, in order to rule out associated fractures. Several classifications of fractures of the fifth metatarsal base have been published in the last 50 years, categorizing these fractures in terms of their location, appearance of the fracture line, type of treatment, healing and complications. Currently, the most frequently used one is the classification developed by Lawrence and Botte. Non-operative treatment is indicated in undisplaced or minimally displaced fractures, fractures in elderly patients and in patients contraindicated for surgery. The method of choice in undisplaced fractures is the Barouk boot with partial weight-bearing as tolerated by the patient, while displaced fractures up to 2 mm are fixed in a low plaster cast (Essex-Lopresti shoe). Operative treatment is indicated in fractures displaced by more than 2 mm or involving more than 30% of the articular surface of the cuboid metatarsal joint. Internal fixation is most commonly performed with the use of intramedullary screw, tension wire band, K-wires or plates. Stress fractures are preferably treated by surgery to reduce the risk of non-union, delayed healing and the risk of refractures. The most common complications associated with treatment of fractures of the fifth metatarsal base include delayed healing, non union development, refractures and patient discomfort.Key words: fractures of the fifth metatarsal base - diagnosis - treatment - complications. PMID- 29444577 TI - Classification of scapular body fractures. AB - INTRODUCTION: The aim of this study is to present, on the basis of 3D CT reconstructions of 187 of scapular body fractures, a clinically oriented classification respecting the biomechanical architecture of the scapula. METHODS: In a series of 375 scapula fractures we identified 187 body fractures in187 patients (157 men, 30 women) with the mean age of 48 years (range; 16100 years). 3D CT reconstructions were obtainedof all fractures, to allow an objective evaluation of the fracture pattern. A total of 46 patients were operated on and their intraoperative findings were correlated with 3D CT reconstructions. Scapular body fractures were deemed to be only those fractures that passed through the biomechanical body of the scapula, i.e. involved at least one of the pillars. Excluded from the study were fractures of the superior angle and of the superior border of the scapula as they were only marginal fractures leaving both pillars intact; scapular neck fractures defined as extra-articular two-part fractures of the lateral angle separating the glenoid from the scapular body; and fractures of the inferior angle of the scapula. Evaluation focused on the course of fracture lines, their relationship to the two pillars, and the number of fragments. A separate fragment was considered to be only such a fragment that carried part of the circumference of the biomechanical body. The intercalary fragmentsbroken off the central part of the infraspinous fossa were not included. RESULTS: We identified three basic groups of scapular body fractures, i.e. those involving only the spinal pillar, those involving only the lateral pillar and fractures affecting both pillars. Our series included 12 fractures of the spinal pillar, of these in 8 cases the main fracture line passed vertically from the supraspinous fossa of the central part of the pillar toward the medial border of the infraspinous fossa; in 4 cases the scapular spine base was broken off the scapular body. In all the cases, the lateral pillar was left intact and fragments were displaced only insignificantly. Therefore all these fractures were treated non-operatively. A total of 143 fractures involved the lateral pillar. All of them were fractures of the infraspinous portion of the scapular body, i.e. the infraspinous fossa, with the main fracture line propagating from the lateral pillar. This fracture pattern was divided on the basis of the number of circumference fragments into three subtypes, namely two-part (88), three-part (31) and comminuted (24) fractures. Fractures of both pillars were recorded in 32 cases. This fracture had two patterns, one (11 fractures) with a fracture line running through the spinal pillar close to the spinomedial angle to the superior angle of the scapula, and the other (21 fractures) with the main fracture line passing through the weakened central part of the scapular spine. This comminuted type was the most severe injury to the scapular body. The fracture line always propagated through the weakened central part of the spinal pillar. The fracture of the lateral pillar was displaced in all cases more than that of the spinal pillar. CONCLUSION: Classification of scapular body fractures based on involvement of the pillars of the scapular body is logical and simple. It always requires a 3D CT reconstruction, including subtraction of the surrounding bones. It respects the anatomical structure of the scapula and may serve also as a therapeutic guidance in preoperative planning.Key words: scapula scapula fractures scapular body fractures - classification classification of scapular body fractures.

AB - INTRODUCTION: The aim of this study is to describe the anatomy of fractures of the inferior angle and the adjacent part of the scapular body, based on 3D CT reconstructions. METHOD: In a series of 375 scapular fractures, we identified a total of 20 fractures of the inferior angle of the scapular body (13 men, 7 women), with a mean patient age of 50 years (range 3373). In all fractures, 3D CT reconstructions were obtained, allowing an objective evaluation of the fracture pattern with a focus on the size and shape of the inferior angle fragment, propagation of the fracture line to the lateral and medial borders of the infraspinous part of the scapular body, fragment displacement and any additional fracture of the ipsilateral scapula and the shoulder girdle. RESULTS: We identified a total of 5 types of fracture involving the distal half of the infraspinous part of the scapular body. The first type, recorded in 5 cases, affected only the apex of the inferior angle, with a small part of the adjacent medial border. The second type, occurring in 4 cases, involved fractures separating the entire inferior angle. The third type, represented by 4 cases, was characterized by a fracture line starting medially close above the inferior angle and passing proximolaterally. The separated fragment had a shape of a big drop, carrying also the distal half of the lateral pillar in addition to the inferior angle. In the fourth type identified in 5 fractures, the separated fragment was formed both by the inferior angle and a variable part of the medial border. The fifth type, being by its nature a transition to the fracture of the infraspinous part of the body, was recorded in 2 cases, with the same V-shaped fragment. CONCLUSION: Fractures of the inferior angle and the adjacent part of the scapular body are groups of fractures differing from other infraspinous fractures of the scapular body. Although these fractures are highly variable in terms of shape, they have the same course of fracture line and the manner of displacement.Key words: scapula scapula fractures scapular body fractures inferior angle classification of scapular body fractures.

The objective of the article is to identify factors influencing reintervention rate after surgical treatment of kidney stone disease either by percutaneous nephrolitholapaxy or flexible ureterorenoscopy. METHOD: A retrospective study was conducted on 149 patients who underwent a surgery for a kidney stone disease at the Urological department of F.D. Roosevelt hospital Banska Bystrica from January 2015 till June 2015. The cohort included 60 women at average age of 57 (range 28-91) and 89 men at average age of 58 (range 30-92). Patients were treated by percutaneous litholapaxy (67 cases) and flexible ureterorenoscopy (82 cases, including 72 using dusting technique). Factors with potential influence on probability of repeated intervention during following 12 months have been studied and statistically analyzed. For the statistical analysis we used the generalized linear regression framework (GLM Generalized Linear Model) with the stepwise forward modeling approach. RESULTS: Using the significance level of 5% the statistically significant factors affecting the probability of the re-intervention for ipsilateral kidney stone disease are the stone size (p-value 0.0035) and the postoperative stone free status (p-value 0.0418). Other studied factors as demographical data (age, gender), surgical method (percutaneous nephrolitolapaxy or flexible ureterorenoscopy), stone count, postoperative draining system (nefrostomy or JJ stent) did not have any statistically significant impact. CONCLUSION: Patients could benefit from early diagnosis which could lead to earlier identification of smaller stones. Perfect operative technique with intraoperative achievement of stone free status is important to lower the need of repeated intervention.Key words: kidney stone disease - reintervention residual fragments.

AB - INTRODUCTION: At most vascular surgery departments, transperitoneal approach predominates in resections of the aortic aneurysms. For difficult reconstructions of the aorta in the visceral segment, a left flank retroperitoneal approach is used most frequently. METHOD: The authors retrospectively evaluate the left retroperitoneal approach in the management of abdominal aortic aneurysms during a 10-year period. From the total number of 445 operated patients, the left-sided retroperitoneal approach was used in 23 cases. RESULT: All operated patients survived. Average hospital stay was 10 days in the case of elective operations. CONCLUSION: Based on favorable results, the authors confirm that left-sided retroperitoneal approach is rightly considered as a choice in the technically demanding reconstruction of the aorta in the visceral segment.Key words: aortic aneurysm visceral segment of the aorta retroperitoneal approach.

AB - INTRODUCTION: Pancreatic cancer (PDAC) is one of the most aggressive malignancies. Its incidence increases worldwide and, despite the developments in cancer research, mortality rates have not decreased. Poor prognosis of the disease is due to many factors, mainly late diagnosis. Distant metastases and peritoneal carcinomatosis are caused by hematogenous and lymphogenous spreading of the tumorous cells. One of the factors that may influence patient survival are so-called circulating tumor cells (CTCs). The aim of our work was to evaluate the possible influence of CTCs on the survival of patients with PDAC. METHOD: We included patients who underwent a radical or palliative surgical intervention at the First Department of Surgery of Medical Faculty and University Hospital in Olomouc between 1 January 2008 and 31 December 2012. The required samples for CTCs detection were taken from each patient. The detection of the CTCs was performed using real-time RT-PCR. The results were statistically processed and evaluated. RESULTS: We included 126 patients in total, of which 88 were treated radically and 38 received palliative treatment. Mean age was 63 years in patients with radical and 64 years in patients with palliative surgery. Mean survival time in radically treated patients was 29.6 months, in patients with palliative treatment the mean survival time was 8.5 months. The survival time of radically treated patients with CTCs was 27.2 months, without CTCs it was 33.8 months. CONCLUSION: We did not prove a statistically significant difference in survival between radically treated PDAC patients with and without detected CTCs in our work.Key words: pancreatic cancer - circulating tumor cells survival. PMID- 29444582 TI - Short Communication: Dolutegravir-Based Regimens Are Active in Integrase Strand Transfer Inhibitor-Naive Patients with Nucleoside Reverse Transcriptase Inhibitor Resistance. AB - In the SAILING study, dolutegravir demonstrated superior virologic efficacy compared with raltegravir in treatment-experienced, integrase strand transfer inhibitor (INSTI)-naive patients with HIV-1 who harbored resistance to >=2 antiretroviral drug classes. Significantly fewer dolutegravir-treated patients demonstrated virologic failure with treatment-emergent resistance than raltegravir-treated patients through 48 weeks. Investigator-selected background therapy (ISBT) included at least one fully active agent, selected on the basis of resistance analysis. Genotypic and phenotypic resistance testing were performed on baseline and time-of-failure samples from patients with protocol-defined virologic failure (PDVF). A post hoc analysis of SAILING (N = 715; 354 dolutegravir, 361 raltegravir) assessed efficacy in subpopulations defined by ISBT activity, resistance profiles, and treatment history. When ISBT contained only nucleoside reverse transcriptase inhibitors (NRTIs), PDVF occurred in 0% (0/32) of dolutegravir-treated patients and 21.9% (7/32) of raltegravir-treated patients (p = .005). In patients harboring M184 V whose ISBT contained lamivudine or emtricitabine plus a second NRTI, 0% (0/13) of dolutegravir- and 33.3% (4/12) of raltegravir-treated patients (p = .026) experienced PDVF. Among patients receiving protease inhibitor (PI)-containing ISBT, 6.0% (18/300) of dolutegravir treated patients versus 11.8% (36/305) of raltegravir-treated patients (p = .012) experienced PDVF. Darunavir/ritonavir was part of ISBT in 130 dolutegravir treated patients and 145 raltegravir-treated patients; 6 (4.6%) and 12 (8.3%), respectively, experienced PDVF (difference -3.7%; 95% confidence interval: -10.1% to 2.5%; p = .256). There was no or less virologic failure in treatment experienced, INSTI-naive subjects receiving dolutegravir versus raltegravir, even when the ISBT was suboptimal or NRTI resistance was present at baseline. These findings are not explained by the use of PI/ritonavir-containing ISBT.

AB - Children of mothers affected by gestational diabetes mellitus (GDM) are at higher risk of long-term cardio-metabolic diseases. We explore the diet and physical activity knowledge and practices of Australian-born and overseas-born mothers with GDM history, for their three- to four-year-old children following antenatal health promotion education at a tertiary hospital. We conducted face-to-face, semi-structured interviews with 8 Australian-born and 15 overseas-born mothers with a history of GDM. Findings indicated that mothers of both groups were unaware of the increased health risks of their GDM for their children and could not recall receiving specific dietary or physical activity advice aimed at future child health. Their understanding of the diet and physical activity recommendations was inconsistent. Mothers of both groups expressed concern about the lack of reiteration of child health promotion messages following childbirth, particularly at postnatal follow-up visits. Diet and physical activity of the children of overseas-born mothers were adversely affected by inadequate maternal understanding of the recommendations due to language barriers, and child weight, healthy eating, and physical activity patterns derived from their home countries. We recommend enhanced health education for women with GDM on the future child health risks and their reduction by healthy lifestyle choices. This needs to be culturally relevant and reiterated after pregnancy. PMID- 29444584 TI - Complication Rates and Short-Term Outcomes After Operative Hammertoe Correction in Older Patients. AB - BACKGROUND: Hammertoe deformities are the most common lesser toe deformity. To date, no studies have looked at outcomes of operative management in the geriatric population, which may be at greater risk for complications or functional compromise because of comorbidities. METHODS: Data on 58 patients undergoing operative correction of hammertoe deformities were prospectively collected. Clinical outcomes were assessed using preoperative and postoperative visual analogue scale (VAS) and Short Form Health Survey (SF-36) scores with a minimum of 6-month follow-up. Patients were divided into 2 groups on the basis of age at the time of surgery: younger than 65 and 65 and older. Complication rates and mean VAS and SF-36 improvement were compared. Forty-seven patients met inclusion criteria (7 men, 40 women), with 26 patients (37 toes) in the younger cohort and 21 patients (39 toes) in the older cohort. RESULTS: Overall, patients demonstrated significant improvement from baseline to 6 and 12 months postoperatively in VAS ( P < .001 and P < .001) and SF-36 ( P < .001 and P < .001) scores. Mean improvement in VAS and SF-36 scores was not significantly different between the groups at 6 and 12 months postoperatively. Complications occurred in 13.5% and 10.3% of patients in the younger and older cohorts, respectively. CONCLUSIONS: Outcomes of operative correction of hammertoe deformities in older patients were similar to outcomes in younger patients after greater than 6 months of follow-up. Overall improvement in VAS and SF-36 was statistically significant for both cohorts. There was no associated increase in complications for older patients.

AB - Background Transarterial embolization with particles is a relatively common treatment method in both malignant and benign disorders. Permanent occlusion of the uterine arteries may sometimes be disadvantageous. Purpose To compare the local tissue effects, possible side effects, and extent of recanalization following uterine artery embolization, using either degradable or non-degradable microspheres in a sheep model. Material and Methods In 22 female sheep, the uterine artery (UA) was unilaterally, superselectively embolized, with either degradable starch microspheres-DSM (group A) or calibrated gelatin coated spherical shape tris-acryl microspheres-TGMS (group B). The completion of embolization was confirmed by angiography. The animals were kept in the animal research facilities for 14 days and sacrificed following new angiographic evaluation. Gross and histological examination of the uterus and other organs was performed. Results The procedure was successful in all animals. At final angiographic evaluation recanalization was found in 82% of the ewes in group A and in 18% in group B. At histopathological examination, tissue impairment was similar in both groups, whereas vascular changes were more pronounced in the TGMS group. Conclusion Embolization with DSM was associated with significantly higher degree of recanalization, than after embolization with TGMS. PMID- 29444586 TI - Sex differences in pericardial adipose tissue assessed by PET/CT and association with cardiometabolic risk. AB - Background Recent studies suggest that pericardial adipose tissue (PAT) is associated with whole body adiposity and insulin resistance. Moreover, the incidence of cardiovascular disease (CVD) differs between men and women. Although CVD is more prevalent in men, women suffering from CVD have a higher mortality compared to men. Differences in PAT may account for some of the observed sex differences in manifestations of CVD. Purpose To assess pericardial adipose tissue (PAT) as a biomarker for cardiometabolic risk and to assess potential sex differences. Material and Methods We studied 303 individuals (151 women, 152 men; mean age = 57 +/- 17 years) across the weight spectrum. PAT and abdominal adipose tissue were quantified using clinical computed tomography (CT) scans obtained as part of a positron emission tomography (PET)/CT. Cardiometabolic risk factors were assessed from medical records. Linear regression and receiver operating characteristic (ROC) curve analyses were performed to evaluate associations between PAT and cardiometabolic risk. Results PAT was higher in overweight and obese individuals compared to lean individuals and higher in men compared to women. PAT was positively associated with body mass index, abdominal fat ( P < 0.0001), fasting glucose, and serum lipids ( P < 0.05) with stronger associations in women than in men. PAT was accurate in detecting the prevalence of the metabolic syndrome with 74% sensitivity and 76% specificity (AUC = 0.80). Conclusion PAT is associated with measures of cardiometabolic risk and these associations are stronger in women compared to men. PAT could serve as a biomarker for opportunistic screening for cardiometabolic risk in patients undergoing chest CT. PMID- 29444588 TI - Periaortic Adipose Tissue Compared With Peribrachial Adipose Tissue Mass as Markers and Possible Modulators of Cardiometabolic Risk. AB - Increased perivascular fat mass contributes to cardiometabolic risk (CMR). High peribrachial adipose tissue (PBAT) associates with insulin resistance independently of established CMR parameters. It is unknown to what extent periaortic adipose tissue (PAAT) may have a similar impact. In 95 participants, precise quantification of total adipose tissue, PBAT, PAAT, visceral adipose tissue (VAT), and liver fat (LF) content was performed by whole-body magnetic resonance imaging. Insulin sensitivity was determined by oral glucose tolerance test and carotid intima-media thickness (cIMT) by high-resolution ultrasound. In univariate analyses, PAAT correlated with PBAT (beta = .65, P < .0001). A negative correlation of PAAT (beta = -.35, P = .0002) and PBAT (beta = -.43, P < .0001) with insulin sensitivity was observed. While in a stepwise forward regression analysis the relationship of PAAT with insulin sensitivity was no longer significant after adjustment for VAT, LF content, and other CMR factors ( P = 0.42), PBAT still correlated with insulin sensitivity ( r2 = .35, P = .01). The association between PAAT and cIMT (beta = .49, P < .0001) remained significant after adjustment for these variables ( r2 = .42, P = .0001). Although PAAT and PBAT strongly correlate, PAAT is not associated with insulin resistance, but with cIMT. Therefore, PAAT and PBAT may act differently as possible modulators of insulin resistance and subclinical atherosclerosis.

AB - Studies evaluating the risk of peripheral arterial disease (PAD) in patients with abdominal aortic aneurysm (AAA) are limited. We used insurance claims data of Taiwan to establish a cohort of 6590 patients with AAA newly diagnosed from 2000 to 2008 and 6590 controls without AAA matched by propensity score. The subsequent incidence density rates of PAD were estimated in both cohorts by the end of 2011, and the AAA cohort to the non-AAA cohort hazard ratios (HRs) of PAD were calculated using Cox proportional hazards models. The incidence density of PAD in the AAA cohort was 3.7-fold greater than that in the non-AAA cohort (14.1 vs 3.66 per 1000 person-years) with an adjusted HR of 3.56 (95% confidence interval [CI] = 2.89-4.39). For those without comorbidities, PAD in the AAA cohort was 7.4-fold greater than that in the non-AAA cohort (12.0 vs 1.61 per 1000 person-years) with an adjusted HR of 6.70 (95% CI = 4.43-10.1). The incidence of PAD in patients with ruptured AAA was lower than that in patients without rupture (6.95 vs 15.0 per 1000 person-years). This study demonstrates that patients with AAA are at increased risk of developing PAD.

(VBF) is commonly known as the oriental blueberry in Korea. The aim of this study was to evaluate the antidepressant-like effects of water VBF extract (VBFW) in a mouse model of chronic restraint stress (CRS) and to identify the underlying mechanisms of its action. The behavioral effects of VBFW were assessed in the forced swim test (FST) and open field test (OFT). The levels of serum corticosterone (CORT), brain monoamines, in addition to the extracellular signal-regulated kinases (ERKs)/protein kinase B (Akt) signaling pathway were evaluated. VBFW treatment significantly reduced the immobility time and increased swimming time in FST without altering the locomotor activity in unstressed mice. Furthermore, CRS mice treated with VBFW exhibited a significantly decreased immobility time in FST and serum CORT, increased locomotor activity in OFT, and enhanced brain monoamine neurotransmitters. Similarly, VBFW significantly upregulated the ERKs/Akt signaling pathway in the hippocampus and PFC. In addition, VBFW may reverse CORT-induced cell death by enhancing cyclic AMP-responsive element-binding protein expression through the up regulation of ERKs/Akt signaling pathways. In addition, VBFW showed the strong antagonistic effect of the 5-HT[Formula: see text] receptor by inhibiting 5-HT induced intracellular Ca[Formula: see text] and ERK1/2 phosphorylation. Our study provides evidence that antidepressant-like effects of VBFW might be mediated by the regulation of monoaminergic systems and glucocorticoids, which is possibly associated with neuroprotective effects and antagonism of 5-HT[Formula: see text] receptor.

AB - Background Classical galactosaemia (OMIM #230400) is a rare disorder of carbohydrate metabolism caused by deficiency of the galactose-1-phosphate uridyltransferase enzyme. The pathophysiology of the long-term complications, mainly cognitive, neurological and female fertility problems, remains poorly understood. Current clinical methods of biochemical monitoring lack precision and individualization with an identified need for improved biomarkers for this condition. Methods We report the development and detailed validation of an automated ultraperformance liquid chromatography N-glycan analytical method of high peak resolution applied to galactose incorporation into human serum IgG. Samples are prepared on 96-well plates and the workflow features rapid glycoprotein denaturation, enzymatic glycan release, glycan purification on solid supported hydrazide, fluorescent labelling and post-labelling clean-up with solid phase extraction. Results This method is shown to be accurate and precise with repeatability (cumulative coefficients of variation) of 2.0 and 8.5%, respectively, for G0/G1 and G0/G2 ratios. Both serum and processed N-glycan samples were found to be stable at room temperature and in freeze-thaw experiments. Conclusions This high-throughput method of IgG galactose incorporation is robust, affordable and simple. This method is validated with the potential to apply as a biomarker for treatment outcomes for galactosaemia. PMID- 29444594 TI - Placental Tissue in Colon and Liver.

AB - Senescence of chondrocytes and cartilage degeneration induced by the proinflammatory cytokine interleukin-1beta is associated with the pathogenesis of osteoarthritis. The cannabinoid receptor 1 has been involved in the pathological development of various diseases. Here, we evaluated whether activation of cannabinoid receptor 1 using its selective agonist arachidonyl-2-chloroethylamide had an influence on cellular senescence induced by interleukin-1betain human chondrocytes. Our findings demonstrate that agonist arachidonyl-2 chloroethylamidedecreased senescence-associated beta-galactosidase activity and cell cycle arrest in the G0/G1 phase induced by interleukin-1beta. Importantly, our results display interleukin-1betatreatment significantly increased the expressions of senescence genes (caveolin-1, PAI-1 and p21), which were prevented by agonist arachidonyl-2-chloroethylamide treatment. However, it was noticed that these functions of agonist arachidonyl-2-chloroethylamide were abolished by the cannabinoid receptor 1 selective antagonist AM251, suggesting the involvement of cannabinoid receptor 1. Also, our results indicate that agonist arachidonyl-2 chloroethylamide enhanced the expression of sirt1. These findings suggest that activation of cannabinoid receptor 1 by agonist arachidonyl-2-chloroethylamide might have a protective effect against pro-inflammatory cytokines such as interleukin-1beta-induced chondrocytes senescence in osteoarthritis patients. Impact statement Senescence of chondrocytes and cartilage degeneration induced by the proinflammatory cytokine interleukin-1beta (IL-1beta) are associated with the pathogenesis of osteoarthritis (OA). Here we found that: (a) the CB1 agonist ACEA abolished IL-1beta-induced senescence and cell arrest in chondrocytes; (b) the CB1 agonist ACEA also abolished IL-1beta-induced expression of caveolin-1, PAI-1, and p21; PMID- 29444598 TI - Venous outlet syndrome caused by capillary hemangioma of the subclavian vein.

AB - Currently, the prevention and treatment of hypertensive crises especially when it occurs with serious adverse outcomes have led to worldwide controversy. Despite of clinical possibilities of multiple agents, clinical failures still occur frequently. Therefore, early evaluations and observations of different therapies on appropriate animals should be emphasized. In the present study, an animal model for hypertensive crises emergencies was firstly established and experimentally testified. Five-month-male spontaneously hypertensive rat was consecutively fed with 60%-Kcal fat diet for four, six, and eight weeks with body weight and blood pressure monitored every two weeks, and then followed by an acute vasoconstriction stress of 5-min ice-bath treatment in the 4-h time interval of two adrenaline injections (0.8 mg/kg). Forty-four biochemical parameters were detected, covering hepatic and renal function, blood glucose and lipid levels, myocardial enzymes and energy metabolisms, blood coagulative and anti-coagulative system, oxidative stress and anti-inflammatory cytokine, blood viscosity, and RAAS system. Six tissues including heart, brain, liver, kidney, coronary arteries, and mesenteries were removed for pathological observations with hematoxylin-eosin staining. As a result, multi-organ dysfunctions in the heart, brain, liver, kidney, vascular endothelium, and blood system were testified in the modeling rats at weeks 6 and 8. In conclusion, severe consequences of this animal model were highly similar to those in hypertensive crises emergencies, which could be further utilized in the early intervention of hypertensive crises emergencies including the possible risk factors control and efficient therapies assessment. Impact statement In the late 90s, numerous reports predicted that 1-2% of hypertensive individuals would undergo hypertensive crises (HPC) and figures reached as high as 7% when no antihypertensive therapies were administrated. Currently, clinical failures appear frequently due to the improper or excessive medication regimen instead of the illness itself. Therefore, early evaluations and observations of HPC on appropriate animal models ahead of patients should be discussed and emphasized more widely. In the present study, an appropriate animal model for HPC emergencies was firstly established, in which the consequences of long-term high fat diet feeding followed by an acute vasoconstriction stress on the spontaneously hypertensive rats were experimentally testified. The proposed model would have a wide application prospects in early intervention of HPC emergencies including the controls of possible risk factors and assessments of efficient therapies. PMID- 29444599 TI - Correlation between epicardial fat thickness and aortic valve sclerosis. AB - Background Epicardial fat is a true visceral fat deposit with adverse effects through the secretion of numerous proinflammatory and proatherogenic cytokines. Previous studies showed an association between aortic valve sclerosis and coronary artery disease. The aim of this study was to determine the correlation between epicardial fat thickness and aortic valve sclerosis. Method The study involved 225 patients who were admitted for coronary angiography due to new-onset angina. They underwent transthoracic echocardiography and epicardial fat thickness was determined. The sclerosis scoring of each aortic cusp, average aortic valve sclerosis score index, and left ventricular ejection fraction were determined. The variables of left ventricular diastolic function obtained included the early diastolic velocity determined by transmitral pulsed Doppler, and early mitral annular velocity measured by tissue Doppler. Results Patients with an epicardial fat thickness >=7 mm were older ( p = 0.006), with more hypertension ( p = 0.045) and hyperlipidemia ( p < 0.001). Their average aortic valve sclerosis score index was higher (1.4 +/- 1.02 vs. 0.86 +/- 0.85, p = 0.001), and left ventricular ejection fraction and early mitral annular velocity were lower ( p < 0.001 and 0.03, respectively). They also exhibited more left ventricular hypertrophy ( p = 0.026) and a trend towards more significant coronary artery disease and 3-vessel disease ( p = 0.086 and 0.073, respectively). Conclusion Our findings confirm that epicardial fat as a marker of visceral adipose tissue may have an important role in promoting inflammatory and atherosclerotic changes in the aortic valve. PMID- 29444600 TI - Extracorporeal membrane oxygenation as a rescue measure after thoracic surgery. AB - Background Extracorporeal membrane oxygenation is used for many different conditions including respiratory distress, cardiogenic shock, and trauma. In these patient groups, extracorporeal membrane oxygenation has been extensively studied. Recently, it has been used as a rescue measure in patients experiencing acute respiratory distress after thoracic surgery. The goal of our study was to examine the efficacy and cost-effectiveness of extracorporeal membrane oxygenation as a rescue measure after thoracic surgery at a single center. Methods We conducted a retrospective review of all patients who received extracorporeal membrane oxygenation after thoracic surgery at the University of Kentucky from January 9, 2012 to January 9, 2017. Eight patients were identified. Results The average time on extracorporeal membrane oxygenation was 9.125 days, and the average hospital stay was 65.125 days. Of the 8 patients placed on extracorporeal membrane oxygenation, 3 survived to discharge. Of the 3 patients who survived to discharge, 1 died within 6 months and 2 have been followed up for less than 4 months. The average total charge per patient was calculated to be $1,053,551, and the average charge per day was $16,177. The contribution margin was $109,200 per case. Conclusions Extracorporeal membrane oxygenation is a tool that saves lives in many different patient populations but it does not appear to be as effective in patients experiencing acute respiratory distress syndrome after thoracic surgery. Extracorporeal membrane oxygenation in this group also uses a tremendous amount of hospital resources. PMID- 29444601 TI - The role of thoracic surgery in extracorporeal membrane oxygenation services. AB - Background Recent evidence surrounding the use of venovenous extracorporeal membrane oxygenation in treating acute respiratory failure has led to the expansion of extracorporeal membrane oxygenation services worldwide. The high rate of complications related to venovenous extracorporeal membrane oxygenation often requires intervention by specialist thoracic surgeons. This study aimed to investigate the role of specialist thoracic surgeons within the multidisciplinary team managing these high-risk patients. Methods We retrospectively reviewed 90 patients who received venovenous extracorporeal membrane oxygenation at our tertiary referral center between December 2011 and May 2015. Four patients who underwent lung transplantation were excluded. Results We found that 29.1% (25/86) of patients on venovenous extracorporeal membrane oxygenation had undergone a thoracic intervention. A total of 82 interventions were performed: 11 thoracotomies, 49 chest drains, 13 rigid bronchoscopies, 4 flexible bronchoscopies, 4 temporary endobronchial blockers, and 1 sternotomy. Of the 11 thoracotomies, 3 were reexplorations. Survival to discharge for patients who underwent thoracic surgical interventions was 72% (18/25). Conclusions Our experience has demonstrated that a large proportion of patients receiving venovenous extracorporeal membrane oxygenation require a thoracic intervention, many of which are major intraoperative procedures. Patients on venovenous extracorporeal membrane oxygenation have benefited from rapid on-site access to thoracic surgical services to manage these challenging life-threatening complications. PMID- 29444602 TI - Evaluating Integrative Cancer Clinics With the Claim Assessment Profile: An Example With the InspireHealth Clinic. AB - BACKGROUND: The evaluation of freestanding integrative cancer clinical programs is challenging and is rarely done. We have developed an approach called the Claim Assessment Profile (CAP) to identify whether evaluation of a practice is justified, feasible, and likely to provide useful information. OBJECTIVES: A CAP was performed in order to (1) clarify the healing claims at InspireHealth, an integrative oncology treatment program, by defining the most important impacts on its clients; (2) gather information about current research capacity at the clinic; and (3) create a program theory and path model for use in prospective research. STUDY DESIGN/METHODS: This case study design incorporates methods from a variety of rapid assessment approaches. Procedures included site visits to observe the program, structured qualitative interviews with 26 providers and staff, surveys to capture descriptive data about the program, and observational data on program implementation. RESULTS: The InspireHealth program is a well established, multi-site, thriving integrative oncology clinical practice that focuses on patient support, motivation, and health behavior engagement. It delivers patient-centered care via a standardized treatment protocol. There arehigh levels of research interest from staff and resources by which to conduct research. CONCLUSIONS: This analysis provides the primary descriptive and claims clarification of an integrative oncology treatment program, an evaluation readiness report, a detailed logic model explicating program theory, and a clinical outcomes path model for conducting prospective research. Prospective evaluation of this program would be feasible and valuable, adding to our knowledge base of integrative cancer therapies. PMID- 29444603 TI - Safety of Combined Treatment With Monoclonal Antibodies and Viscum album L Preparations. AB - Combination strategies involving chemotherapy and monoclonal antibodies (mAb) are commonly used in attempts to produce better clinical outcomes. This practice has led to new and ongoing toxicities that may lead to reductions in dose or noncompliance, limiting the effectiveness of treatment. Viscum album L (VA) preparations are widely used in Europe as additive therapy and have been associated with reduced chemotherapy-related adverse reactions and increased health-related quality of life. Concomitant VA therapy might also reduce toxicity related to mAb. This retrospective study investigated the safety of combined treatment with VA and mAb in cancer patients. A total of 43 patients had combined therapy (474 exposures); 12 had VA without mAb (129 exposures), and 8 had mAb without VA (68 exposures). Most patients (89.3%) received concomitant chemotherapy or supportive therapies. A total of 34 patients (60.7%) experienced 142 adverse events (AEs). Leucopenia (14.1% of all events), acneiform rash (8.5%), and stomatitis (6.3%) occurred most frequently. Longitudinal logistic regression analysis suggested a nearly 5 times higher odds of experiencing an AE following treatment with mAb compared with mAb plus VA (95% CI = 1.53-16.14). Our results, together with theoretical consideration of potential botanical-drug interactions, suggest that combined treatment with VA and mAb is safe. PMID- 29444604 TI - The Circadian System and Cancer: It's About Time! PMID- 29444605 TI - Anxious attachment and excessive acquisition: The mediating roles of anthropomorphism and distress intolerance. AB - Background and aims Most individuals with hoarding disorder (HD) are prone to excessively acquiring new possessions. Understanding the factors that contribute to this collecting behavior will allow us to develop better treatment approaches for HD. The aim of this study was to test our assumption that an anxious attachment style is associated with a tendency to anthropomorphize comforting objects and an inability to tolerate distress, which in turn leads to excessive acquisition. Methods A total of 361 participants with subclinical to clinical acquisition problems (77.8% female) completed a series of self-report measures. Results As expected, greater anxious attachment was related to greater distress intolerance and stronger tendencies to anthropomorphize inanimate objects. In turn, greater distress intolerance and anthropomorphism were related to more excessive buying and greater acquisition of free items. Examination of the pathways and indirect effects showed support for double mediation rather than serial mediation, as distress intolerance did not predict anthropomorphism. Discussion and conclusion These novel findings, if replicated, suggest that adding treatment modules that target improving distress tolerance and reducing anthropomorphism to standard treatment for HD may lead to further reductions in excessive acquiring. PMID- 29444606 TI - The links between healthy, problematic, and addicted Internet use regarding comorbidities and self-concept-related characteristics. AB - Background Addicted Internet users present with higher rates of comorbidities, e.g., attention-deficit hyperactivity disorder (ADHD), depressive, and anxiety disorders. In addition, deficits in self-concept-related characteristics were found in addicted Internet gamers and social network users. The aim of this study was to examine the links between healthy, problematic, and addicted Internet use regarding comorbidities and self-concept-related characteristics. The association between recently developed ADHD-like symptoms without an underlying diagnosis and addictive Internet use was also examined. Methods n = 79 healthy controls, n = 35 problematic, and n = 93 addicted Internet users were assessed for comorbidities, social and emotional competencies, body image, self-esteem, and perceived stress. Apart from an ADHD-diagnosis, recently developed ADHD-like symptoms were also assessed. Results Addicted users showed more self-concept-related deficits and higher rates of comorbidities with ADHD, depressive, and anxiety disorders. Addicted and problematic users showed similarities in the prevalence of cluster B personality disorders and decreased levels of characteristics related to emotional intelligence. Participants with recently developed ADHD-like symptoms scored higher in lifetime and current severity of Internet use compared with those without ADHD symptoms. Addicted participants with recently developed ADHD symptoms showed higher lifetime Internet use severity compared with those without any symptoms. Conclusions Our findings indicate that cluster B personality disorders and premorbid problems in emotional intelligence might present a link between problematic and addictive Internet use. Furthermore, the findings provide a first indication that addictive Internet use is related to ADHD-like symptoms. Symptoms of ADHD should therefore be assessed against the background of possible addicted Internet use. PMID- 29444608 TI - Acute autoimmune myocarditis and hepatitis due to ipilimumab monotherapy for malignant melanoma. AB - An important agent in melanoma therapy, ipilimumab is associated with autoimmune toxicity. Two cases of autoimmune pericarditis and large pericardial effusion have been documented with its use. Reports of myocardial toxicity have surfaced with this agent, mainly when used in combination with PD1 blockade. We present herein a case of autoimmune myocarditis leading to biventricular failure after four doses of IV ipilimumab 3 mg/kg as a single agent. Furthermore, this toxic effect may be anticipated with PD1 inhibitors. Increased clinical suspicion, prompt diagnosis, and steroid therapy are crucial to ensure a favorable clinical outcome. PMID- 29444607 TI - Psychometric evaluation of Persian Nomophobia Questionnaire: Differential item functioning and measurement invariance across gender. AB - Background and aims Research examining problematic mobile phone use has increased markedly over the past 5 years and has been related to "no mobile phone phobia" (so-called nomophobia). The 20-item Nomophobia Questionnaire (NMP-Q) is the only instrument that assesses nomophobia with an underlying theoretical structure and robust psychometric testing. This study aimed to confirm the construct validity of the Persian NMP-Q using Rasch and confirmatory factor analysis (CFA) models. Methods After ensuring the linguistic validity, Rasch models were used to examine the unidimensionality of each Persian NMP-Q factor among 3,216 Iranian adolescents and CFAs were used to confirm its four-factor structure. Differential item functioning (DIF) and multigroup CFA were used to examine whether males and females interpreted the NMP-Q similarly, including item content and NMP-Q structure. Results Each factor was unidimensional according to the Rach findings, and the four-factor structure was supported by CFA. Two items did not quite fit the Rasch models (Item 14: "I would be nervous because I could not know if someone had tried to get a hold of me;" Item 9: "If I could not check my smartphone for a while, I would feel a desire to check it"). No DIF items were found across gender and measurement invariance was supported in multigroup CFA across gender. Conclusions Due to the satisfactory psychometric properties, it is concluded that the Persian NMP-Q can be used to assess nomophobia among adolescents. Moreover, NMP-Q users may compare its scores between genders in the knowledge that there are no score differences contributed by different understandings of NMP-Q items. PMID- 29444609 TI - Optimization of resources by drug management: A multicentred web-administered study on the use of ipilimumab in Italy. AB - Objective In a scenario of new expensive cancer therapies entering the market, strategies of optimisation and cost containment are crucial in oncology care. Better management of drug waste and centralization of drug preparation can be effective strategies to achieve these goals. The aim of this work is to describe the economic management of a high cost anticancer drug (ipilimumab) in some Italian reference centres. Methods This was an observational, multicentred study in which economical and clinical data of 21 cancer centres (418 patients) were collected during the enrollment period from February 2013 to August 2014. The follow-up period ended in July 2015. Results Participants purchased 10.7% more vials of ipilimumab than necessary for compounding. The results were variable among centres, and only five centres had a deviation lower than 5% between the drug purchased and the drug prescribed. Hospitals applying the drug day reached a statistically significant residual of drug effectively used compared to the amount prescribed (P = 0.018). Consequently, the price for treating a model patient was significantly lower in those hospitals (median spare of 7456 euro per patient). Conclusions This study demonstrated that the careful management of drug waste and the application of drug-day, through a proper selection of vial and the ability to use the leftover drug, can generate economic savings. However, tailoring the drug stock to clinical need is still an open issue which deserves further analysis. PMID- 29444610 TI - Evaluation of adherence to Mediterranean diet in medical students at Kocaeli University, Turkey. AB - Introduction This study was conducted to evaluate the eating habits of medical students at Kocaeli University in northwest Turkey in terms of their ability to apply their academic knowledge regarding healthy lifestyles to their own lives using the Mediterranean Diet Quality Index (KIDMED). Methods In this cross sectional study, a questionnaire including demographic information and the KIDMED index was administered to 354 medical school students (206 first-year and 148 third-year students). The students' sex, body mass index, KIDMED score, place of residence, smoking habit, media screen time, and regular exercising variables were evaluated. Results The KIDMED score was -2 to 8 (3.8 +/- 1.9) among all students, -1 to 8 (3.9 +/- 2.0) among first-year students, and -1 to 8 (3.6 +/- 1.9) among third-year students. In total, 59.1% of females and 40.9% of males among first-year students showed moderate adherence to the Mediterranean diet, and female students showed better adherence to the Mediterranean diet than males among third-year students. Conclusion Medical students at Kocaeli University in Turkey showed inadequate application of their academic knowledge about healthy living to their own lives. PMID- 29444611 TI - The Effect of Goreisan on the Prevention of Chronic Subdural Hematoma Recurrence: Multi-Center Randomized Controlled Study. AB - The relatively high rate of post-operative recurrence in the treatment of chronic subdural hematoma (CSDH) is a significant problem. Goreisan is an herbal medicine that exhibits a hydragogue effect by inhibiting the expression of aquaporins, and its efficacy in preventing post-operative CSDH recurrence has been suggested by several case trials. This multi-center prospective randomized controlled trial was performed to investigate the preventative effect of goreisan on post operative CSDH recurrence. Patients with symptomatic CSDH over 60 years old undergoing burr hole surgery were enrolled in this study. The patients were randomly allocated to the control group or the goreisan group, in which oral administration of goreisan (7.5 g daily) was continued for 12 weeks. The primary end-point was the post-operative recurrence rate at 12 weeks and the secondary end-point was hematoma volume reduction rates on computed tomography scan at 12 weeks. The analyses were performed not only on patients of all ages older than 60 years, but also on patients divided into those over or under 75 years old. One hundred and eighty patients were followed and analyzed (the control group, n = 88; the goreisan group, n = 92). The recurrence rates considering patients of all ages and patients under 75 years old were relatively low in the goreisan group but without a significant difference. The hematoma volume reduction rates showed no significant difference. Based on the results of the present study, a larger scale study including more cases is necessary in future to confirm the efficacy of goreisan. PMID- 29444612 TI - Circadian Clock Synchronization of the Cell Cycle in Zebrafish Occurs through a Gating Mechanism Rather Than a Period-phase Locking Process. AB - Studies from a number of model systems have shown that the circadian clock controls expression of key cell cycle checkpoints, thus providing permissive or inhibitory windows in which specific cell cycle events can occur. However, a major question remains: Is the clock actually regulating the cell cycle through such a gating mechanism or, alternatively, is there a coupling process that controls the speed of cell cycle progression? Using our light-responsive zebrafish cell lines, we address this issue directly by synchronizing the cell cycle in culture simply by changing the entraining light-dark (LD) cycle in the incubator without the need for pharmacological intervention. Our results show that the cell cycle rapidly reentrains to a shifted LD cycle within 36 h, with changes in p21 expression and subsequent S phase timing occurring within the first few hours of resetting. Reentrainment of mitosis appears to lag S phase resetting by 1 circadian cycle. The range of entrainment of the zebrafish clock to differing LD cycles is large, from 16 to 32 hour periods. We exploited this feature to explore cell cycle entrainment at both the population and single cell levels. At the population level, cell cycle length is shortened or lengthened under corresponding T-cycles, suggesting that a 1:1 coupling mechanism is capable of either speeding up or slowing down the cell cycle. However, analysis at the single cell level reveals that this, in fact, is not true and that a gating mechanism is the fundamental method of timed cell cycle regulation in zebrafish. Cell cycle length at the single cell level is virtually unaltered with varying T cycles. PMID- 29444613 TI - Characteristics and outcomes of patients with intellectual disability admitted to a specialist inpatient rehabilitation service. AB - Rehabilitation services for people with mental illnesses have been extensively researched. However, services with similar aims and specifications for patients with intellectual disabilities (IDs) have had little focus. This study describes the characteristics and outcomes of 21 patients admitted to a specialist ID rehabilitation service over an 8-year time frame. Rather that solely accepting 'step-down' referrals, some patients were referred from community settings. During the study, 20 patients were discharged, 80% to lower levels of service restriction, while 14.3% to higher levels. The study suggested that rehabilitation services have an important role within the wider service model for people with ID. Within the service studied, patients were referred from both higher and lower levels of restriction, suggesting the rehabilitation service 'bridged the gap' between inpatient and community settings, supporting the aim of caring for patients in the least restrictive setting for their needs. PMID- 29444614 TI - In vitro anti-influenza virus effect of total flavonoid from Trollius ledebouri Reichb. AB - Objective To investigate the in vitro antivirus effect of total flavonoid from Trollius ledebouri Reichb (TFTLR). Methods Madin-Darby canine kidney (MDCK) and Human epithelial type 2 (HEp-2) cell lines were used to test the antivirus effect of TFTLR on nine virus subtypes: four H1N1, one H3N2, and four other subtypes prevalent in North China. Tamiflu, Ribavirin and Lianhua Qingwen were used as active comparators. Comprehensive molecular pathway analyses of TFTLR-H1N1 and TFTLR-H3N2 relationships were also conducted. Results TFTLR inhibited MDCK cell lesions induced by H1N1 subtypes (A/FM1/1/47, A/Puerto Rico/8/1934 H1N1, A1/Tianjin Jinnan/15/2009, and A/Brisbane/59/2007) and by the H3N2 Brisbane/10/2009 strain. TFTLR inhibitory concentration (IC)50 values against these viruses were 0.13, 0.07, 0.06, 0.14, and 0.07 mg/ml, respectively; and therapeutic index (TI) values were 8.62, 16.0, 18.67, 8.0, and 16.0, respectively. TFTLR showed no effect on parainfluenza virus type 1, herpes simplex virus type 1, respiratory syncytial virus, and coxsackie group B virus type 4. Pathway analysis revealed possible functional therapeutic mechanisms for TFTLR against H1N1 and H3N2 infections. Conclusion TFTLR may represent a potential therapeutic agent against influenza A subtypes H1N1 and H3N2 that are prevalent in North China, and should be investigated further. PMID- 29444615 TI - The mysterious polyamines, the enigmatic Barr body, and lupus: comment on the article by Kim et al. AB - "Polyamine patterns in plasma of patients with systemic lupus erythematosus and fever" by Kim et al. provides insight into possible involvement of polyamines in systemic lupus erythematosus (SLE). The authors report decreases in N1 acetylspermidine, spermidine, spermine, and N1-acetylcadaverine and increased cadaverine in SLE. Polyamine involvement in many cellular processes and their unique characteristics (high charge, length, flexibility, and ubiquity) give polyamines importance in health and disease. In this editorial, I describe a scenario, the "X chromosome-nucleolus nexus" hypothesis, in which polyamines could initially rise because of cellular stress. This rise in polyamines increases nucleolar size and activity. Polyamines are critical in the nucleolar assembly of ribonucleoprotein complexes, such as ribosomes. However, the expanding nucleolus could disrupt a neighboring inactive X chromosome (Barr body). This disruption opens additional polyamine genes that alter polyamine levels and types through wasteful synthesis and recycling of polyamines. This could include a decrease in the key polyamines spermidine and spermine, which are critical to nucleolar functioning. And this can decrease S-adenosylmethionine needed for cellular methylation leading to hypomethylation seen in SLE. As a result, the nucleolus can no longer respond properly to future stresses. With altered polyamine levels and types in the nucleolus, many RNA transcripts, proteins, and ribonucleoprotein complexes assembled in the nucleolus may be trapped in autoantigenic conformations. Many of the major autoantigens in SLE are, at least transiently, components of the nucleolus. Therefore, the observations of decreased polyamines reported by Kim et al. could be important in the formation of autoantigens. PMID- 29444616 TI - Endovascular treatment of cerebral aneurysm after renal transplantation in polycystic kidney disease. AB - Background Patients with polycystic kidney disease have a higher prevalence of intracranial aneurysms and may progress to renal failure requiring transplantation. The endovascular treatment of intracranial aneurysms may improve prognosis, since rupture often causes premature death or disability, but the nephrotoxicity risk associated with contrast medium must be always considered in cases of renal impairment. Methods A 55-year-old female patient with polycystic kidney disease and grafted kidney associated with anterior communicant artery aneurysm was successfully treated by embolization. Results The renal function remained normal after the procedure. To the authors' knowledge, this is the first case of endovascular treatment of brain aneurysm in a transplanted patient reported in the medical literature. Conclusions The endovascular procedure in renal transplant patients is feasible and can be considered to treat this population. Further studies and cases are needed to confirm its safety. PMID- 29444617 TI - Hemodynamic impingement and the initiation of intracranial side-wall aneurysms. AB - Objective The natural history intracranial aneurysms (IA) remains poorly understood despite significant morbidity and mortality associated with IA rupture. Hemodynamic impingement resulting in elevations in wall shear stress and wall shear stress gradient (WSSG) has been shown to induce aneurysmal remodeling at arterial bifurcations. We investigate the hemodynamic environment specific to side-wall pre-aneurysmal vasculature. We hypothesize that fluid impingement and secondary flow patterns play a role in side-wall aneurysm initiation. Methods Eight side-wall internal carotid artery aneurysms from the Aneurisk repository were identified. Pre-aneurysmal vasculature was algorithmically reconstructed. Blood flow was simulated with computational fluid dynamic simulations. An indicator of isolated fluid impingement energy was developed by insetting the vessel surface and calculating the impinging component of the fluid dynamic pressure. Results Isolated fluid impingement was found to be elevated in the area of aneurysm initiation in 8/8 cases. The underlying fluid flow for each area of initiation was found to harbor secondary flow patterns known as Dean's vortices, the result of changes in momentum imparted by bends in the internal carotid artery (ICA). Conclusion Isolated fluid impingement and secondary flow patterns may play a major role in the initiation of side-wall aneurysm initiation. We are unable to determine if this role is through direct or indirect mechanisms but hypothesize that elevations in isolated fluid impingement mark areas of cerebral vasculature that are at risk for aneurysm initiation. Thus, this indicator provides vascular locations to focus future study of side-wall aneurysm initiation. PMID- 29444618 TI - Pathophysiology of drug induced weight and metabolic effects: findings from an RCT in healthy volunteers treated with olanzapine, iloperidone, or placebo. AB - Second generation antipsychotics are prescribed for an increasing number of psychiatric conditions, despite variable associations with weight gain, dyslipidemia, and impaired glucose tolerance. The mechanism(s) of the apparent causal relationships between these medications and metabolic effects have been inadequately defined and are potentially confounded by genetic risk of mental illness, attendant lifestyle, and concomitant medications. Therefore, we conducted a study in which 24 healthy volunteers were randomized to olanzapine (highly weight-gain liability), iloperidone (less weight-gain liability), or placebo treatment for 28 days under double-blind conditions. We hypothesized that antipsychotics induce weight gain primarily through increased caloric intake, which causes secondary dyslipidemia and insulin resistance. Subjects were phenotyped pre- and post-treatment for body weight, adiposity by dual energy X ray absorptiometry, energy expenditure by indirect calorimetry, food intake, oral glucose tolerance, plasma lipids, glucose, insulin, and other hormones. We found significantly increased food intake and body weight but no change in energy expenditure in olanzapine-treated subjects, with associated trends towards lipid abnormalities and insulin resistance the extent of which were presumably limited by the duration of treatment. Iloperidone treatment led to modest non-significant and placebo no weightgain, lipid increases and alterations in insulin metabolism. We conclude that second generation antipsychotic drugs, as represented by olanzapine, produce their weight and metabolic effects, predominantly, by increasing food intake which leads to weight gain that in turn induces metabolic consequences, but also through other direct effects on lipid and glucose metabolism independant of food intake and weight gain. PMID- 29444620 TI - Differential anxiety-like responses in NOD/ShiLtJ and C57BL/6J mice following experimental autoimmune encephalomyelitis induction and oral gavage. AB - Oral gavage is commonly used in pre-clinical drug evaluation, but is potentially aversive and may induce behavioral effects independent of compounds under investigation. This study examined the combined effects of repeated oral gavage and disease induction on anxiety-like behavior in the experimental autoimmune encephalomyelitis (EAE) model of multiple sclerosis. The C57BL/6J and NOD/ShiLtJ EAE variants were exposed to sham-EAE induction or untreated control conditions, and either daily oral gavage or home cage conditions. Anxiety-like behavior was subsequently assessed in the elevated plus maze. C57BL/6J mice exhibited increased anxiety-like behavior, relative to NOD/ShiLtJ mice, in response to repeated gavage, whereas sham-EAE induction and repeated gavage were associated with increased anxiety-like behavior in NOD/ShiLtJ mice. Thus, exposure to the induction procedure and repeated gavage differentially altered subsequent anxiety like behavior in the two EAE variants. Future pre-clinical studies should rely on prior evaluation of parameters of the experimental design using sham-EAE mice. Additionally, less aversive administration routes should be utilized wherever possible to ensure that procedures do not distort effects of the therapeutic under investigation. PMID- 29444619 TI - Clinical Value of Long Noncoding RNA HOTAIR as a Novel Biomarker in Digestive Cancers: A Meta-Analysis. AB - HOX transcript antisense intergenic RNA has been reported to serve as an important prognostic biomarker in several types of cancers. However, the clinical value of HOX transcript antisense intergenic RNA in digestive cancers remains unclear. Therefore, we tried to investigate the clinical role of expression of HOX transcript antisense intergenic RNA as a prognostic indicator in digestive cancers by a meta-analysis. Literature collection was performed by searching the PubMed, Embase, Web of Science, and Cochrane Library databases (up to October 7, 2017). A quantitative meta-analysis was conducted to assess the eligible articles on the prognostic value of HOX transcript antisense intergenic RNA in digestive cancers. The pooled hazard ratios or odds ratios with 95% confidence intervals were used to evaluate the association between expression of HOX transcript antisense intergenic RNA and clinical outcomes. A total of 1844 patients from 22 studies were included in this meta-analysis. The results found a significant association between expression of HOX transcript antisense intergenic RNA and poor overall survival in digestive cancers (pooled hazard ratio = 2.19, 95% confidence interval, 1.86-2.57, P < .001). Furthermore, subgroup analysis showed that tumor type, region, Newcastle-Ottawa scale, and sample size did not alter the predictive value of HOX transcript antisense intergenic RNA as an independent factor for patients' survival. In addition, we also revealed that the clinicopathological characteristics such as differentiation, lymph node metastasis, tumor node metastasis (TNM) stage, and distant metastasis were positively related to expression of HOX transcript antisense intergenic RNA digestive cancers. In conclusion, our results suggested high expression of HOX transcript antisense intergenic RNA was correlated with poor clinical outcomes and may serve as a novel prognostic biomarker for patients with digestive cancers. PMID- 29444621 TI - Excitotoxicity in the pathogenesis of neurological and psychiatric disorders: Therapeutic implications. AB - Neurological and psychiatric disorders are leading contributors to the global disease burden, having a serious impact on the quality of life of both patients and their relatives. Although the molecular events underlying these heterogeneous diseases remain poorly understood, some studies have raised the idea of common mechanisms involved. In excitotoxicity, there is an excessive activation of glutamate receptors by excitatory amino acids, leading to neuronal damage. Thus, the excessive release of glutamate can lead to a dysregulation of Ca2+ homeostasis, triggering the production of free radicals and oxidative stress, mitochondrial dysfunction and eventually cell death. Although there is a consensus in considering excitotoxicity as a hallmark in most neurodegenerative diseases, increasing evidence points to the relevant role of this pathological mechanism in other illnesses affecting the central nervous system. Consequently, antagonists of glutamate receptors are used in current treatments or in clinical trials in both neurological and psychiatric disorders. However, drugs modulating other aspects of the excitotoxic mechanism could be more beneficial. This review discusses how excitotoxicity is involved in the pathogenesis of different neurological and psychiatric disorders and the promising strategies targeting the excitotoxic insult. PMID- 29444622 TI - The Role of Close Relationships in Terror Management: A Systematic Review and Research Agenda. AB - Terror management theory outlines how humans seek self-esteem and worldview validation to manage death-related anxiety. Accumulating evidence reveals that close relationships serve a similar role. However, to date, there has been no synthesis of the literature that delineates when close relationships buffer mortality concerns, under what conditions, on which specific outcomes, and for whom. This systematic review presents over two decades of research to address these questions. Findings from 73 reviewed studies revealed that close relationships serve an important role in buffering death-related anxiety. A range of dispositional and situational moderating factors influence either the activation or inhibition of relational strivings to manage heightened death awareness, the most influential being attachment, gender, and relationship contingent self-esteem. These findings were integrated into an overarching model that highlights some of the conditions under which mortality salience (MS) influences relational outcomes. We conclude by highlighting a range of theoretical and methodological concerns to be addressed by future research. PMID- 29444623 TI - Interpreting Action Research Arm Test Assessment Scores to Plan Treatment. AB - Rasch keyforms can help interpret clinical assessment scores. The Action Research Arm Test (ARAT) is a commonly used assessment, yet no keyform currently exists. The aim is to provide a keyform for the ARAT and demonstrate how a clinician can use the keyform to design optimally challenging rehabilitation sessions. Secondary analysis of ARAT data ( n = 122) using confirmatory factor and Rasch analyses were used to examine the measurement properties and generate a keyform. The item standardized factor loadings were >0.40 (range = 0.82-0.96) and R2 values were >.60 (range = .65-.96). All items exhibited adequate infit statistics with point measure correlations >.60 (range = .72-.97). Person reliability was .98, and person separation was 7.07. Item-difficulty measures ranged from -2.78 logits to 2.64 logits. The ARAT has strong measurement properties, and a keyform was provided. We showed how the keyform can be utilized by clinicians to interpret scores, set goals, and plan treatment. PMID- 29444624 TI - Examining Guided and Directed Cues in Strategy Training and Usual Rehabilitation. AB - Therapist approach and feedback during rehabilitation may influence patient outcomes. It is unclear how much guided cueing, the approach used in strategy training, is present in usual rehabilitation care. We compared the frequency of guided and directed cueing in strategy training sessions with cueing in usual care occupational and physical therapy. We videotaped strategy training, occupational therapy, and physical therapy sessions among 20 patients admitted to inpatient rehabilitation after stroke. Using a standardized coding scheme, we coded and analyzed frequencies of therapists' cues (guided or directed). The proportion of guided cues was significantly higher in strategy training intervention (42%) compared with occupational therapy (4%) and physical therapy (3%). Preliminary research suggests that guided cueing may be more prevalent in strategy training than in usual care. Given that guided cueing provides more opportunity for patients to take an active role in their rehabilitation, guided cueing may lead to superior outcomes. PMID- 29444625 TI - Brazilian Photographic Figure Rating Scale for Men: Psychometric Investigation. AB - As a follow-up to an earlier study from this research group involving women, this study examined the reliability and validity of the Brazilian Photographic Figure Rating Scale for Men (BPFRS-M) for evaluating men's body perception and dissatisfaction. In both versions of the Brazilian Photographic Figure Rating Scale (BPFRS), respondents viewed eight photographic images (seven distorted and one accurate) of themselves in standard poses and then offered self-ratings. In both versions, 10 experts assessed content validity and demonstrated high agreement (defined by ratings of 4-5 on a 5-point scale) that BPFRS items measured underlying constructs: and experts showed high (>70%) interrater agreement. For this version, participants were 149 Brazilian men (Mean = 22.4; SD = 2.7 years). Pearson correlations demonstrated convergence between the BPFRS-M and two related scales of men's body image. Positive correlations ( p = .0001) were found between actual and respondent-perceived body mass index (BMI). Test retest and Kappa Index confirmed temporal stability. The BPFRS-M can accurately and reliably assess body perception and dissatisfaction in young men. PMID- 29444626 TI - Experiences of Intimate Partner Violence Victims With Police and the Justice System in Canada. AB - Legal responses to intimate partner violence (IPV) can determine whether and how those exposed to IPV seek help. Understanding the victim's perspective is essential to developing policy and practice standards, as well as informing professionals working in policing and the justice system. In this survey study, we utilized a subset of 2,831 people who reported experiencing IPV to examine (a) rates of reporting to the police; (b) experiences with, and perceived helpfulness of, police; (c) rates of involvement with the criminal and family law systems, including protection orders; and (d) experiences with, and perceived helpfulness of, the justice system. Data were analyzed using descriptive statistics for closed-ended survey questions and content analysis of text responses. More than 35% of victims reported a violent incident to the police, and perceptions of helpfulness were mixed. Fewer victims were involved with the criminal and family law systems, and their satisfaction also varied. Text responses provided insight into possible reasons for the variability found in experiences, for example, the proposed role of victim and system expectations, and respondents' perception that getting help depends on "being lucky" with the officials encountered. PMID- 29444627 TI - Beliefs About Sexual Intimate Partner Violence Perpetration Among Adolescents in South Africa. AB - Sexual intimate partner violence (IPV) is a public health problem worldwide. Research regarding beliefs about perpetrating sexual IPV is, however, limited. This study investigated attitudes, social influence, and self-efficacy beliefs and intentions toward perpetrating sexual IPV among Grade 8 adolescents ( M age = 13.73, SD = 1.04) in the Western Cape Province of South Africa. The study sample was taken from the baseline data of the Promoting sexual and reproductive health among adolescents in Southern and Eastern Africa (PREPARE) study, a cluster randomized controlled trial. Young adolescents ( N = 2,199), from 42 randomly selected high schools, participated in the study and answered a paper-and-pencil questionnaire. Multivariate ANOVA were conducted to assess differences in beliefs and intention toward perpetrating sexual IPV between boys and girls, and between perpetrators and nonperpetrators. Results showed that boys were more frequently perpetrators (11.3% vs. 3.2%) and victims (13.6% vs. 6.4%) of sexual IPV than girls. Boys' attitudes toward perpetrating sexual IPV were more supportive than girls'. Boys perceived their social network to be more likely to think that putting pressure on a boyfriend or girlfriend to have sex is okay, and boys had a lower self-efficacy to refrain from pressuring a boyfriend or girlfriend to have sex compared with girls. Both boys and girls, who have perpetrated sexual IPV, had more tolerant attitude, social influence, and self-efficacy beliefs toward sexual IPV perpetration, compared with nonperpetrators. Intention not to perpetrate sexual IPV did not differ between boys and girls, or between perpetrators and nonperpetrators. Our findings suggest that interventions should address attitude and social influence beliefs regarding sexual IPV perpetration. More attention should be given to sexual IPV perpetration among boys. Given that sexual IPV victimization and perpetration are significantly linked, prevention of sexual IPV perpetration seems to be of utmost importance. PMID- 29444628 TI - Assisting the Investigation of Stranger Rapes: Predicting the Criminal Record of U.K. Stranger Rapists From Their Crime Scene Behaviors. AB - Davies, Wittebrood, and Jackson (1997) were among the first to investigate whether offense behaviors are predictive of criminal history, with the findings of their paper then utilized by the National Crime Agency (NCA) Behavioral Investigative Advisors (BIAs) when assisting rape investigations. The aim of the study was to replicate this seminal paper with a larger contemporary sample of U.K. stranger rapists as identified by NCA. Data from 474 adult male stranger rapists were obtained in relation to 22 crime scene behaviors and nine preconviction variables. Results indicated significant differences between the Davies et al. original data set and this contemporary data set in both the behaviors and the preconvictions they displayed. The contemporary sample was significantly less likely to use sighting precautions, use violence, and take fingerprint precautions. This sample was also significantly less likely to have any of the preconviction crime types, with the exception of drugs offenses. When exploring the current data set of stranger rapists, statistical analyses indicated a number of key offense behaviors that were able to predict the criminal history of stranger rapists. However, contrary to previous research, no behaviors were found to be associated with sexual offense preconvictions. The results highlight that behaviors and characteristics of stranger sex offenders have changed since the 1990s. The implications for practice are discussed. PMID- 29444629 TI - Canine Clitoral Carcinoma: A Clinical, Cytologic, Histopathologic, Immunohistochemical, and Ultrastructural Study. AB - Vaginal and vulvar tumors are uncommon in dogs. Knowledge of canine primary clitoral neoplasia is restricted to a few case reports, and only carcinomas have been reported. Cytologic and histologic features reported in the literature seem to overlap with those of canine apocrine gland anal sac adenocarcinoma (AGASA). Clinical features also recall those of canine AGASA, such as locoregional metastases and hypercalcemia of malignancy (HM). In this study, 6 cases of primary canine clitoral carcinomas (CCCs), with and without HM, were investigated by means of cytology, histopathology, electron microscopy, and immunohistochemistry for neuroendocrine markers including chromogranin A (CGA), synaptophysin (SYN), neuron-specific enolase (NSE), and S-100. In all 6 tumors, cytologic findings were consistent with malignant epithelial neoplasia of apocrine gland origin. The tumors examined were classified into 3 different histological patterns representing different degrees of differentiation: tubular, solid, and rosette type. Both CGA and SYN were mildly expressed in 2 of 6 tumors, while NSE was consistently expressed in all 6 cases. None of the tumors were S 100 positive. Transmission electron microscopy revealed electron-dense cytoplasmic granules compatible with neuroendocrine granules in all 6 cases. CCCs presented clinicopathologic features resembling AGASAs with neuroendocrine characteristics, and 2 of 6 neoplasms were considered as carcinomas with neuroendocrine differentiation and were positive for 3 neuroendocrine markers. CCCs can often present with HM, and long-term outcome is likely poor. Our study concludes that CCC seems to be a rare tumor, but it might be underestimated because of the overlapping features with AGASA. Further studies should aim to define the true incidence of this disease. PMID- 29444630 TI - Congenital Ocular Abnormalities in Free-Ranging White-Tailed Deer. AB - Congenital ocular abnormalities in cervids have been previously reported as individual cases from various regions of the United States and include microphthalmia, anophthalmia, congenital cataracts, dermoids, and colobomata. A common underlying cause for these abnormalities, such as nutritional deficiencies, environmental toxin exposures, or genetic mutations, has not been established. This retrospective study summarized and compared cases of suspected congenital ocular abnormalities in free-ranging white-tailed deer ( Odocoileus virginianus) submitted to the Southeastern Cooperative Wildlife Disease Study (SCWDS) in Athens, Georgia, to the preexisting literature. Of 3645 accessions of white-tailed deer submitted to SCWDS, 15 qualifying case records were found. An additional 15 cases were reported previously in the literature. Conditions described in SCWDS cases included microphthalmia (8/15), congenital cataracts (3/15), anophthalmia (2/15), colobomata (1/15), anterior segment dysgenesis (1/15), ectopic lacrimal gland tissue (1/15), and congenital blindness with corneal opacity (1/15). Most (11/15; 73%) of the SCWDS cases were male fawns with an average age of 4 months at presentation, consistent with previously described cases. Most animals had bilateral abnormalities with few extraocular congenital abnormalities, also consistent with existing reports. Cases were variably tested for various infectious agents at the time of submission; 2 cases were seropositive for bluetongue virus. Spatiotemporal clustering of cases was not evident. This study provided a concise and systematic summary of known existing cases of congenital ocular defects in fawns but did not identify a cause. PMID- 29444631 TI - Accumulation of Laforin and Other Related Proteins in Canine Lafora Disease With EPM2B Repeat Expansion. AB - Canine Lafora disease (LD) is an autosomal recessive genetic disorder causing nonfatal structural epilepsy, mainly affecting miniature wirehaired dachshunds. Repeat expansion in the EPM2B gene causes a functional impairment of the ubiquitin ligase malin which regulates glycogen metabolism. Abnormally structured glycogen accumulates and develop polyglucosan bodies predominantly in the central nervous system. The authors performed a comprehensive clinical, genetic, and pathological study of 4 LD cases affecting miniature wirehaired dachshund dogs with EPM2B repeat expansions, with systemic distribution of polyglucosan bodies and accumulation of laforin and other functionally associated proteins in the polyglucosan bodies. Myoclonic seizures first appeared at 7-9 years of age, and the dogs died at 14-16 years of age. Immunohistochemistry for calbindin revealed that the polyglucosan bodies were located in the cell bodies and dendritic processes of Purkinje cells. Polyglucosan bodies were also positive for laforin, hsp70, alpha/beta-synuclein, ubiquitin, LC3, and p62. Laforin-positive polyglucosan bodies were located in neurofilament-positive neurons but not in GFAP-positive astrocytes. In nonneural tissues, periodic acid-Schiff (PAS) positive polyglucosan bodies were observed in the heart, skeletal muscle, liver, apocrine sweat gland, and smooth muscle layer of the urinary bladder. In the skeletal muscle, polyglucosan bodies were observed only in type 1 fibers and not in type 2 fibers. The results indicate that although the repeat expansion of the EPM2B gene is specific to dogs, the immunohistochemical properties of polyglucosan body in canine LD are comparable to human LD. However, important phenotypic variations exist between the 2 species including the affected skeletal muscle fiber type. PMID- 29444632 TI - Immunohistochemical Labeling of Multiple Myeloma Oncogene 1/Interferon Regulatory Factor 4 (MUM1/IRF-4) in Canine Cutaneous Histiocytoma. AB - Multiple myeloma oncogene 1/interferon regulatory factor 4 (MUM1/IRF-4) immunohistochemistry (IHC) is mainly used for diagnostic confirmation of plasma cell tumors (PCTs) in dogs and cats. This article describes MUM1/IRF-4 IHC expression in 20 cases of canine cutaneous histiocytoma (CH) and compares it with 10 cutaneous or mucocutaneous PCTs and 5 cutaneous histiocytic sarcomas (HSs) submitted to the same IHC protocol. All histiocytomas had strong nuclear and variable cytoplasmic immunolabeling for MUM1/IRF-4, whereas all PCTs had strong nuclear and moderate cytoplasmic immunolabeling for MUM1/IRF-4. No MUM1/IRF-4 immunolabeling was detected in the HSs. Although not typically a diagnostic challenge, MUM1/IRF-4 expression may have to be used with caution or in conjunction with additional immunomarkers to differentiate among poorly differentiated round cell tumors, especially when a histiocytic or plasma cell origin is suspected. PMID- 29444633 TI - Talaromycosis (Penicilliosis) in a Cynomolgus Macaque. AB - A sexually mature Chinese-origin female Macaca fascicularis assigned to the high dose group in a 26-week toxicology study with an experimental immunomodulatory therapeutic antibody (a CD40 L antagonist fusion protein) was euthanized at the scheduled terminal sacrifice on study day 192. The animal was healthy at study initiation and remained clinically normal throughout the study. On study day 141, abnormal clinical pathology changes were found during a scheduled evaluation; splenomegaly was detected on study day 149 and supported by ultrasound examination. At the scheduled necropsy, there was marked splenomegaly with a nodular and discolored appearance. Cytologic examination of a splenic impression smear revealed yeast-like organisms within macrophages. Histologically, there was disseminated systemic granulomatous inflammation with 2- to 3-MUm oval, intracytoplasmic yeast-like organisms in multiple organs identified as Talaromyces (Penicillium) marneffei. This organism, not previously reported as a pathogen in macaques, causes an important opportunistic infection in immunosuppressed humans in specific global geographic locations. PMID- 29444634 TI - Evaluation of reaction gap-filling accuracy by randomization. AB - BACKGROUND: Completion of genome-scale flux-balance models using computational reaction gap-filling is a widely used approach, but its accuracy is not well known. RESULTS: We report on computational experiments of reaction gap filling in which we generated degraded versions of the EcoCyc-20.0-GEM model by randomly removing flux-carrying reactions from a growing model. We gap-filled the degraded models and compared the resulting gap-filled models with the original model. Gap filling was performed by the Pathway Tools MetaFlux software using its General Development Mode (GenDev) and its Fast Development Mode (FastDev). We explored 12 GenDev variants including two linear solvers (SCIP and CPLEX) for solving the Mixed Integer Linear Programming (MILP) problems for gap filling; three different sets of linear constraints were applied; and two MILP methods were implemented. We compared these 13 variants according to accuracy, speed, and amount of information returned to the user. CONCLUSIONS: We observed large variation among the performance of the 13 gap-filling variants. Although no variant was best in all dimensions, we found one variant that was fast, accurate, and returned more information to the user. Some gap-filling variants were inaccurate, producing solutions that were non-minimum or invalid (did not enable model growth). The best GenDev variant showed a best average precision of 87% and a best average recall of 61%. FastDev showed an average precision of 71% and an average recall of 59%. Thus, using the most accurate variant, approximately 13% of the gap filled reactions were incorrect (were not the reactions removed from the model), and 39% of gap-filled reactions were not found, suggesting that curation is still an important aspect of metabolic-model development. PMID- 29444635 TI - Diel pattern of circadian clock and storage protein gene expression in leaves and during seed filling in cowpea (Vigna unguiculata). AB - BACKGROUND: Cowpea (Vigna unguiculata) is an important source of protein supply for animal and human nutrition. The major storage globulins VICILIN and LEGUMIN (LEG) are synthesized from several genes including LEGA, LEGB, LEGJ and CVC (CONVICILIN). The current hypothesis is that the plant circadian core clock genes are conserved in a wide array of species and that primary metabolism is to a large extent controlled by the plant circadian clock. Our aim was to investigate a possible link between gene expression of storage proteins and the circadian clock. RESULTS: We identified cowpea orthologues of the core clock genes VunLHY, VunTOC1, VunGI and VunELF3, the protein storage genes VunLEG, VunLEGJ, and VunCVC as well as nine candidate reference genes used in RT-PCR. ELONGATION FACTOR 1-A (ELF1A) resulted the most suitable reference gene. The clock genes VunELF3, VunGI, VunTOC1 and VunLHY showed a rhythmic expression profile in leaves with a typical evening/night and morning/midday phased expression. The diel patterns were not completely robust and only VungGI and VungELF3 retained a rhythmic pattern under free running conditions of darkness. Under field conditions, rhythmicity and phasing apparently faded during early pod and seed development and was regained in ripening pods for VunTOC1 and VunLHY. Mature seeds showed a rhythmic expression of VunGI resembling leaf tissue under controlled growth chamber conditions. Comparing time windows during developmental stages we found that VunCVC and VunLEG were significantly down regulated during the night in mature pods as compared to intermediate ripe pods, while changes in seeds were non-significant due to high variance. The rhythmic expression under field conditions was lost under growth chamber conditions. CONCLUSIONS: The core clock gene network is conserved in cowpea leaves showing a robust diel expression pattern except VunELF3 under growth chamber conditions. There appears to be a clock transcriptional reprogramming in pods and seeds compared to leaves. Storage protein deposition may be circadian regulated under field conditions but the strong environmental signals are not met under artificial growth conditions. Diel expression pattern in field conditions may result in better usage of energy for protein storage. PMID- 29444636 TI - Transcriptome analysis of different growth stages of Aspergillus oryzae reveals dynamic changes of distinct classes of genes during growth. AB - BACKGROUND: The gene expression profile and metabolic pathways of Aspergillus oryzae underlying the anatomical and morphological differentiation across different growth stages have not been fully characterized. The rapid development of next-generation sequencing technologies provides advanced knowledge of the genomic organization of A. oryzae. RESULTS: In this study, we characterized the growth and development of A. oryzae at different growth stages, including the adaptive phase, logarithmic phase, and stationary phase. Our results revealed that A. oryzae undergoes physiological and morphological differentiation across the different stages. RNA-seq was employed to analyze the three stages of A. oryzae, which generated more than 27 million high-quality reads per sample. The analysis of differential gene expression showed more genes expressed differentially upon transition from the adaptive phase to the logarithmic and stationary phases, while relatively steady trend was observed during the transition from the logarithmic phase to the stationary phase. GO classification of the differentially expressed genes among different growth stages revealed that most of these genes were enriched for single-organism process, metabolic process, and catalytic activity. These genes were then subjected to a clustering analysis. The results showed that the cluster with the majority of genes with increased expression upon transition from the adaptive phase to the logarithmic phase, and steady expression from the logarithmic phase to the stationary phase was mainly involved in the carbohydrate and amino acid metabolism. CONCLUSION: Our results provide a foundation for identifying developmentally important genes and understanding the biological processes across various growth stages. PMID- 29444637 TI - Estimated assessment of cumulative dietary exposure to organophosphorus residues from tea infusion in China. AB - BACKGROUND: China has the world's largest tea plantation area in the world. To sustain high yields of the tea, multiple pesticides are used on tea crops to control pests. Organophosphorus (OP) pesticides are among the most widely used types of agricultural pesticides in China. As tea is a significant potential source of exposure to pesticide residues, the public concern has increased in relation to pesticide residues found in tea in China. The aim of the study was to estimate cumulative dietary exposure to OP residues from tea infusion for Chinese tea consumers to determine whether exposure to OP residues from tea infusion is a cause of health concern for tea consumers in China. METHODS: OP residue data were obtained from the China National Monitoring Program on Food Safety (2013-2014), encompassing 1687 tea samples from 12 provinces. Tea consumption data were obtained from the China National Nutrient and Health Survey (2002), comprising 506 tea consumers aged 15-82 years. The transfer rates of residues from tea leaves into tea infusions were obtained from the literature. The relative potency factor (RPF) approach was used to estimate acute cumulative exposure to 20 OP residues from tea infusion using methamidophos as the index compound. Dietary exposure was calculated in a probabilistic way. RESULTS: For tea consumers, the mean and the 99.9th percentile (P99.9) of cumulative dietary exposure to OP residues from tea infusion equalled 0.08 and 1.08 MUg/kg bw/d. When compared with the acute reference dose (ARfD), 10 MUg/kg bw/d for methamidophos, this accounts for 0.8 and 10.8% of the ARfD. CONCLUSIONS: Even when considering OP residues from vegetables, fruits and other foods, there are no health concerns based on acute dietary exposure to OP residues from tea infusion. However, it is necessary to strengthen the management of the OP pesticides used on tea in China to reduce the risk of chronic dietary exposure to OPs from tea infusion. PMID- 29444638 TI - Unusual elevation in Entropy but not in PSI during general anesthesia: a case report. AB - BACKGROUND: EEG monitoring is useful for determining an adequate level of anesthesia. However it is sometimes interfered by various reasons. We describe a case in which we successfully confirmed the adequate depth of anesthesia by monitoring the patient state index (PSI), which was computed from the SedLine monitor data in Root (Masimo) during general anesthesia. Our case showed unusual elevations in entropy, but not in PSI. CASE PRESENTATION: A 34-year-old woman was scheduled for emergency surgery for a left tibial open fracture and a right femoral closed fracture, which were sustained during a traffic accident. Forty five minutes after intubation, the response entropy abruptly increased up to 100 and state entropy to 91. Despite the absence of other abnormal events, the entropy data led to two types of incorrect decisions. The first was owing to the effect of the EMG and the second was misleading during the surgeon's hammering. However, PSI from the SedLine monitor seemed to be less influenced by the same events. CONCLUSIONS: In this report, we suggest that the PSI, derived from new generation SedLine (Root, Masimo) may be a useful parameter for clinically determining the level of sedation. The use of two monitoring devices with different EEG algorithms might be helpful for determining the anesthetic depth and making decisions. PMID- 29444639 TI - Differential expression of mRNA isoforms in the skeletal muscle of pigs with distinct growth and fatness profiles. AB - BACKGROUND: The identification of genes differentially expressed in the skeletal muscle of pigs displaying distinct growth and fatness profiles might contribute to identify the genetic factors that influence the phenotypic variation of such traits. So far, the majority of porcine transcriptomic studies have investigated differences in gene expression at a global scale rather than at the mRNA isoform level. In the current work, we have investigated the differential expression of mRNA isoforms in the gluteus medius (GM) muscle of 52 Duroc HIGH (increased backfat thickness, intramuscular fat and saturated and monounsaturated fatty acids contents) and LOW pigs (opposite phenotype, with an increased polyunsaturated fatty acids content). RESULTS: Our analysis revealed that 10.9% of genes expressed in the GM muscle generate alternative mRNA isoforms, with an average of 2.9 transcripts per gene. By using two different pipelines, one based on the CLC Genomics Workbench and another one on the STAR, RSEM and DESeq2 softwares, we have identified 10 mRNA isoforms that both pipelines categorize as differentially expressed in HIGH vs LOW pigs (P-value < 0.01 and +/-0.6 log2fold change). Only five mRNA isoforms, produced by the ITGA5, SEMA4D, LITAF, TIMP1 and ANXA2 genes, remain significant after correction for multiple testing (q-value < 0.05 and +/-0.6 log2fold-change), being upregulated in HIGH pigs. CONCLUSIONS: The increased levels of specific ITGA5, LITAF, TIMP1 and ANXA2 mRNA isoforms in HIGH pigs is consistent with reports indicating that the overexpression of these four genes is associated with obesity and metabolic disorders in humans. A broader knowledge about the functional attributes of these mRNA variants would be fundamental to elucidate the consequences of transcript diversity on the determinism of porcine phenotypes of economic interest. PMID- 29444640 TI - Cancer screening in Koreans: a focus group approach. AB - BACKGROUND: Cancer is the greatest disease burden in Korea. Cancer screening can reduce the burden of cancer but cancer screening rates among Koreans remain low. The purposes of this study were to a) understand Koreans' beliefs and knowledge about cancer screening, and b) explore preferred strategies for increasing cancer screening utilization. METHODS: We conducted a descriptive, qualitative study using eight face-to-face focus groups with a total of 64 Koreans aged 40 and over. Participants answered semi-structured, open-ended questions assessing their experiences with, and beliefs, knowledge, and opinions about, cancer screening. All interview data were recorded and analyzed in the context of the health belief model (HBM). RESULTS: The most important themes that emerged from the focus group data were (a) perceived susceptibility (most of the participants believed they were not susceptible to cancer; those who perceived themselves susceptible to cancer were reluctant to express it); (b) perceived benefits (early detection and feelings of relief after cancer screening were benefits; participants had screening because they wanted to take advantage of the Korean government's Medical Payment Support program for cancer patients who have participated in the National Cancer Screening program); (c) perceived barriers (no symptoms; self care when having symptoms; widespread distrust of tests, doctors, and hospitals; unkind health care providers; the financial burdens of advanced cancer screening tests; and the discomfort during cancer screening); and (d) knowledge of the causes of cancer (incorrect knowledge including beliefs that stress, personality, and body overuse cause cancer). Almost all of the participants were very knowledgeable about the seriousness of cancer and were confident that they were able to have cancer screening. Participants preferred strategies of cancer screening using group interventions with family or friends; various information delivery methods; information emphasizing the importance of cancer prevention; convenient, free, or inexpensive services; and kind health care providers. CONCLUSIONS: This HBM-based research suggests that beliefs in low susceptibility to cancer, many barriers to cancer screening, and incorrect knowledge should be the foci for increasing cancer screening rates in Koreans. Interventions could change individual cultural beliefs and increase knowledge as well as the quality of health care for Koreans. PMID- 29444641 TI - Oasis 2: improved online analysis of small RNA-seq data. AB - BACKGROUND: Small RNA molecules play important roles in many biological processes and their dysregulation or dysfunction can cause disease. The current method of choice for genome-wide sRNA expression profiling is deep sequencing. RESULTS: Here we present Oasis 2, which is a new main release of the Oasis web application for the detection, differential expression, and classification of small RNAs in deep sequencing data. Compared to its predecessor Oasis, Oasis 2 features a novel and speed-optimized sRNA detection module that supports the identification of small RNAs in any organism with higher accuracy. Next to the improved detection of small RNAs in a target organism, the software now also recognizes potential cross-species miRNAs and viral and bacterial sRNAs in infected samples. In addition, novel miRNAs can now be queried and visualized interactively, providing essential information for over 700 high-quality miRNA predictions across 14 organisms. Robust biomarker signatures can now be obtained using the novel enhanced classification module. CONCLUSIONS: Oasis 2 enables biologists and medical researchers to rapidly analyze and query small RNA deep sequencing data with improved precision, recall, and speed, in an interactive and user-friendly environment. AVAILABILITY AND IMPLEMENTATION: Oasis 2 is implemented in Java, J2EE, mysql, Python, R, PHP and JavaScript. It is freely available at https://oasis.dzne.de. PMID- 29444642 TI - Income inequality in uptake of voluntary versus organised breast cancer screening: evidence from the British Household Panel Survey. AB - BACKGROUND: This paper measures income-related inequality in uptake of breast cancer screening among women before and after a policy change to extend the screening programme to women aged 65 to 70. Prior to programme expansion women aged 50 to 64 were invited for screening under the national cancer screening programme in England and Wales whereas women in the 65 to 70 age cohort could elect to be screened by personally organising a screen. This will give a deeper insight into the nature of inequality in screening and the impact of policies aimed at widening the access related to age on inequality of uptake. METHODS: Taking advantage of this natural experiment, inequality is quantified across the different age cohorts and time periods with the use of concentration indices (CI). Using data from the British Household Panel Survey, information on screening attendance, equivalised household income and age was taken for the three years prior to the programme expansion and the three years immediately following the policy change. RESULTS: Results show that following the expansion, inequality significantly reduced for the 50-64 age group, prior to the expansion there was a pro-rich inequality in screening uptake. There is also evidence of a reduction in income inequality in screening uptake among those aged 65 to 70 and an increase in the number of women attending screening from this older age cohort. CONCLUSIONS: This indicates that an organised breast screening programme is likely to reduce income related inequality over a screening programme where women must organise their own screen. This is important when breast screening is one of the main methods used to detect breast cancer at an earlier stage which improves outcomes for women and reduces treatment costs. PMID- 29444643 TI - Sonographic evaluation of adrenal size in neonates (23 to 41 weeks of gestation). AB - BACKGROUND: Fetal adrenal gland size is known to have a positive correlation with both gestational age and estimated body weight. In contrast, some clinical observations suggest that maturation of the adrenal stress response occurs after 30 weeks of gestation. In this study, adrenal gland size at birth in extremely preterm to term neonates was investigated using ultrasonography to evaluate the adrenal developmental pattern and the impact of prematurity and perinatal factors. METHODS: The area of the right adrenal gland was measured in the first 3 h of life in 350 neonates and corrected for birth weight (BW) to determine the corrected adrenal area index (cAI). The neonates were subdivided into three groups: group 1 (before 30 weeks of gestation), group 2 (30 to 36 weeks), and group 3 (after 37 weeks). Differences in the cAI among the 3 groups were compared to estimate the impact of perinatal factors. RESULTS: The adrenal gland size was measurable in all neonates with gestational age ranging from 23 to 41 weeks. Right adrenal gland area was highly correlated with BW (r = 0.75, p < 0.01). cAI showed a significant negative correlation with gestational age in group 1 (r = - 0.67, p < 0.01), whereas it showed no correlation with gestational age in both groups 2 and 3. As for the impact of perinatal parameters on cAI, only gestational age in group 1 and only fetal distress in group 2 were correlated with cAI. In group 3, perinatal parameters such as fetal distress and low Apgar score were correlated with cAI. CONCLUSIONS: The present study demonstrated that the developmental pattern of fetal adrenal gland was different before and after 30 weeks of gestation, suggesting that the magnitude of adrenal stress response might mature after 30 weeks of gestation. PMID- 29444644 TI - Use of esophageal balloon pressure-volume curve analysis to determine esophageal wall elastance and calibrate raw esophageal pressure: a bench experiment and clinical study. AB - BACKGROUND: Accurate measurement of esophageal pressure (Pes) depends on proper filling of the balloon. Esophageal wall elastance (Ees) may also influence the measurement. We examined the estimation of balloon-surrounding elastance in a bench model and investigated a simplified calibrating procedure of Pes in a balloon with relatively small volume. METHODS: The Cooper balloon catheter (geometric volume of 2.8 ml) was used in the present study. The balloon was progressively inflated in different gas-tight glass chambers with different inner volumes. Chamber elastance was measured by the fitting of chamber pressure and balloon volume. Balloon pressure-volume (P-V) curves were obtained, and the slope of the intermediate linear section was defined as the estimated chamber elastance. Balloon volume tests were also performed in 40 patients under controlled ventilation. The slope of the intermediate linear section on the end expiratory esophageal P-V curve was calculated as the Ees. The balloon volume with the largest Pes tidal swing was defined as the best volume. Pressure generated by the esophageal wall during balloon inflation (Pew) was estimated as the product of Ees and best volume. Because the clinical intermediate linear section enclosed filling volume of 0.6 to 1.4 ml in each of the patient, we simplified the estimation of Ees by only using parameters at these two filling volumes. RESULTS: In the bench experiment, bias (lower and upper limits of agreement) was 0.5 (0.2 to 0.8) cmH2O/ml between the estimated and measured chamber elastance. The intermediate linear section on the clinical and bench P-V curves resembled each other. Median (interquartile range) Ees was 3.3 (2.5-4.1) cmH2O/ml. Clinical best volume was 1.0 (0.8-1.2) ml and ranged from 0.6 to 1.4 ml. Estimated Pew at the best volume was 2.8 (2.5-3.5) cmH2O with a maximum value of 5.2 cmH2O. Compared with the conventional method, bias (lower and upper limits of agreement) of Ees estimated by the simple method was - 0.1 (- 0.7 to 0.6) cmH2O/ml. CONCLUSIONS: The slope of the intermediate linear section on the balloon P-V curve correlated with the balloon-surrounding elastance. The estimation of Ees and calibration of Pes were feasible for a small-volume balloon. TRIAL REGISTRATION: Identifier NCT02976844 . Retrospectively registered on 29 November 2016. PMID- 29444645 TI - How to achieve the desired outcomes of advance care planning in nursing homes: a theory of change. AB - BACKGROUND: Advance care planning (ACP) has been identified as particularly relevant for nursing home residents, but it remains unclear how or under what circumstances ACP works and can best be implemented in such settings. We aimed to develop a theory that outlines the hypothetical causal pathway of ACP in nursing homes, i.e. what changes are expected, by means of which processes and under what circumstances. METHODS: The Theory of Change approach is a participatory method of programme design and evaluation whose underlying intention is to improve understanding of how and why a programme works. It results in a Theory of Change map that visually represents how, why and under what circumstances ACP is expected to work in nursing home settings in Belgium. Using this approach, we integrated the results of two workshops with stakeholders (n = 27) with the results of a contextual analysis and a systematic literature review. RESULTS: We identified two long-term outcomes that ACP can achieve: to improve the correspondence between residents' wishes and the care/treatment they receive and to make sure residents and their family feel involved in planning their future care and are confident their care will be according to their wishes. Besides willingness on the part of nursing home management to implement ACP and act accordingly, other necessary preconditions are identified and put in chronological order. These preconditions serve as precursors to, or requirements for, accomplishing successful ACP. Nine original key intervention components with specific rationales are identified at several levels (resident/family, staff or nursing home) to target the preconditions: selection of a trainer, ensuring engagement by management, training ACP reference persons, in-service education for healthcare staff, information for staff, general practitioners, residents and their family, ACP conversations and documentation, regular reflection sessions, multidisciplinary meetings, and formal monitoring. ONCLUSIONS: The Theory of Change map presented here illustrates a theory of how ACP is expected to work in order to achieve its desired long-term outcomes while highlighting organisational factors that potentially facilitate the implementation and sustainability of ACP. We provide the first comprehensive rationale of how ACP is expected to work in nursing homes, something that has been called for repeatedly. PMID- 29444646 TI - Lack of association between cigarette smoking and Epstein Barr virus reactivation in the nasopharynx in people with elevated EBV IgA antibody titres. AB - BACKGROUND: Subjects with elevated Epstein-Barr virus (EBV) immunoglobulin A (IgA) titers have a higher risk of developing nasopharyngeal carcinoma (NPC), indicating that reactivation of EBV in the local mucosa might be important for NPC carcinogenesis. Cigarette smoking appears to be one of the environmental risk factors for NPC. However, it remains unclear whether smoking-induced nasopharyngeal carcinogenesis acts through reactivating EBV in the nasopharyngeal mucosa. Therefore, this study aims to investigate the association between cigarette smoking and nasopharyngeal EBV reactivation in a NPC high-risk population. METHODS: A NPC high-risk cohort study, established from a population based NPC screening program of 22,816 subjects, consisted of 1045 subjects with elevated serum IgA antibodies against EBV viral capsid antigen (VCA/IgA). Among high-risk subjects, information on detailed cigarette smoking history was collected among 313 male subjects. The associations between cigarette smoking and EBV antibody levels, EBV DNA load of the nasopharynx were analyzed. RESULTS: No significant association was observed between either nasopharyngeal EBV DNA load or serum VCA/IgA titers and smoking status, age at smoking initiation, daily smoking intensity, smoking duration, cigarette type, or pack-years of smoking. Cigarette smoking characteristics in all subgroups did not correlate with nasopharyngeal EBV DNA positivity or EBV VCA/IgA seropositivity. CONCLUSIONS: In a population at high risk of NPC, our study suggests that cigarette smoking is neither associated with nasopharyngeal EBV DNA load nor serum VCA/IgA antibody level. Smoking-associated NPC carcinogenesis may act through other mechanisms than reactivating nasopharyngeal EBV replication. PMID- 29444647 TI - Exposure to revised drinking guidelines and 'COM-B' determinants of behaviour change: descriptive analysis of a monthly cross-sectional survey in England. AB - BACKGROUND: January 2016 saw the publication of proposed revisions to the UK's lower risk drinking guidelines but no sustained promotional activity. This paper aims to explore the impact of publishing guidelines without sustained promotional activity on reported guideline exposure and determinants of behaviour (capability, opportunity and motivation) proposed by the COM-B model. METHODS: Data were collected by a monthly repeat cross-sectional survey of adults (18+) resident in England over 15 months between November 2015 and January 2017 from a total of 16,779 drinkers, as part of the Alcohol Toolkit Study. Trends and associated 95% confidence intervals were described in the proportion of reported exposure to guidelines in the past month and measures of the capability, opportunity and motivation to consume alcohol within drinking guidelines. RESULTS: There was a rise in reported exposure to drinking guidelines in January 2016 (57.6-80.6%) which did not reoccur in January 2017. Following the increase in January 2016, reported exposure reduced slowly but remained significantly higher than in December 2015. In February 2016, there was an increase in measures of capability (31.1% reported tracking units of alcohol consumption and 87.8% considered it easier to drink safely) and opportunity (84.0% perceived their lifestyle as conducive to drinking within guidelines). This change was not maintained in subsequent months. Other measures showed marginal changes between January and February 2016 with no evidence of change in subsequent months. CONCLUSIONS: Following the publication of revised drinking guideline in January 2016, there was a transient increase in exposure to guidelines, and capability and opportunity to drink within the guidelines that diminished over time. The transience and size of the changes indicate that behaviour change is unlikely. Well-designed, theory-based promotional campaigns may be required for drinking guidelines to be an effective public health intervention. PMID- 29444648 TI - School and class-level variations and patterns of physical activity: a multilevel analysis of Danish high school students. AB - BACKGROUND: There is limited knowledge of physical activity (PA) patterns among high school students. High schools plays an important role as context for the students, but it is uncertain to what extent schools influence student participation in PA during leisure time. The purpose of this study is to describe patterns of PA and assess variations between schools and classes in PA, in a large cohort of Danish high school students. METHODS: Self-reported cross sectional data came from The Danish National Youth Study, comprising a total of 70,674 students attending 119 different schools and 3213 classes. Multilevel logistic regressions were applied to evaluate the association between socio demographic variables and patterns of PA, and to assess the impact of schools and classes on PA measures. RESULTS: Students whose parents have achieved a lower level of education, older students and girls of perceived ethnic minority generally participated less in several forms of PA during leisure time. Substantial variations between schools were observed in terms of participation in PA at school during leisure time and in terms of use of active transportation to and from school. The school-level accounted for 9% (intra-class correlation coefficient (ICC) = 0.09 (95% CI: 0.06-0.11)) and 8% (ICC = 0.08 (95% CI: 0.07 0.11)) of the variation for participation in PA during leisure time and active transportation. CONCLUSION: Overall, students whose parents achieved a lower level of education, older students and girls of perceived ethnic minority represent vulnerable groups in relation to participation in several forms of PA during leisure time. The ICCs indicate that schools, in particular, have the potential to influence participation in PA at school during leisure time and active transportation to and from school. Thus, high schools should encourage and facilitate activities aimed at engaging students in PA during leisure time as well as encourage active transportation. PMID- 29444649 TI - Patterns of pleural pressure amplitude and respiratory rate changes during therapeutic thoracentesis. AB - BACKGROUND: Although the impact of therapeutic thoracentesis on lung function and blood gases has been evaluated in several studies, some physiological aspects of pleural fluid withdrawal remain unknown. The aim of the study was to assess the changes in pleural pressure amplitude (Pplampl) during the respiratory cycle and respiratory rate (RR) in patients undergoing pleural fluid withdrawal. METHODS: The study included 23 patients with symptomatic pleural effusion. Baseline pleural pressure curves were registered with a digital electronic manometer. Then, the registrations were repeated after the withdrawal of consecutive portions of pleural fluid (200 ml up to 1000 ml and 100 ml above 1000 ml). In all patients the pleural pressure curves were analyzed in five points, at 0, 25%, 50%, 75% and 100% of the relative volume of pleural effusion withdrawn in particular patients. RESULTS: There were 11 and 12 patients with right sided and left sided pleural effusion, respectively (14 M, 9F, median age 68, range 46-85 years). The most common cause of pleural effusion were malignancies (20 pts., 87%). The median total volume of withdrawn pleural fluid was 1800 (IQR 1500-2400) ml. After termination of pleural fluid withdrawal Pplampl increased in 22/23 patients compared to baseline. The median Pplampl increased from 3.4 (2.4-5.9) cmH2O to 10.7 (8.1-15.6) cmH2O (p < 0.0001). Three patterns of Pplampl changes were identified. Although the patterns of RR changes were more diversified, a significant increase between RR at baseline and the last measurement point was found (p = 0.0097). CONCLUSIONS: In conclusion, therapeutic thoracentesis is associated with significant changes in Pplampl during the respiratory cycle. In the vast majority of patients Pplampl increased steadily during pleural fluid withdrawal. There was also an increase in RR. The significance of these changes should be elucidated in further studies. TRIAL REGISTRATION: ClinicalTrial.gov, registration number: NCT02192138 , registration date: July 1st, 2014. PMID- 29444650 TI - Designing a behavioral intervention using the COM-B model and the theoretical domains framework to promote gas stove use in rural Guatemala: a formative research study. AB - BACKGROUND: Three billion people use solid cooking fuels, and 4 million people die from household air pollution annually. Shifting households to clean fuels, like liquefied petroleum gas (LPG), may protect health only if stoves are consistently used. Few studies have used an implementation science framework to systematically assess "de-implementation" of traditional stoves, and none have done so with pregnant women who are more likely to adopt new behaviors. We evaluated an introduced LPG stove coupled with a phased behavioral intervention to encourage exclusive gas stove use among pregnant women in rural Guatemala. METHODS: We enrolled 50 women at < 20 weeks gestation in this prospective cohort study. All women received a free 3-burner LPG stove and ten tank refills. We conducted formative research using COM-B Model and Theoretical Domains Framework (TDF). This included thematic analysis of focus group findings and classes delivered to 25 pregnant women (Phase 1). In Phase 2, we complemented classes with a home-based tailored behavioral intervention with a different group of 25 pregnant women. We mapped 35 TDF constructs onto survey questions. To evaluate stove use, we placed temperature sensors on wood and gas stoves and estimated fraction of stove use three times during pregnancy and twice during the first month after infant birth. RESULTS: Class attendance rates were above 92%. We discussed feasible ways to reduce HAP exposure, proper stove use, maintenance and safety. We addressed food preferences, ease of cooking and time savings through cooking demonstrations. In Phase 2, the COM-B framework revealed that other household members needed to be involved if the gas stove was to be consistently used. Social identity and empowerment were key in decisions about stove repairs and LPG tank refills. The seven intervention functions included training, education, persuasion, incentivization, modelling, enablement and environmental restructuring. Wood stove use dropped upon introduction of the gas stove from 6.4 h to 1.9 h. CONCLUSIONS: This is the first study using the COM-B Model to develop a behavioral intervention that promotes household-level sustained use of LPG stoves. This study lays the groundwork for a future LPG stove intervention trial coupled with a behavioral change intervention.

PMID- 29444651 TI - Perceived health and work-environment related problems and associated subjective production loss in an academic population. AB - BACKGROUND: The aim was to investigate the prevalence of health problems and work environment problems and how these are associated with subjective production loss among women and men at an academic workplace. An additional aim was to investigate whether there were differences between women and men according to age group, years at current workplace, academic rank or managerial position. METHODS: A questionnaire was sent in 2011 to all employees at a Swedish university (n = 5144). Only researchers and teachers were included in the study (n = 3207). Spearman correlations were performed to investigate differences in health and work environment problems. Employees who reported having experienced work environment or health problems in the previous seven days (n = 1475) were included in the analyses in order to investigate differences in subjective production loss. This was done using Student's t-test, One-way Anova and generalized linear models. RESULTS: The response rate was 63% (n = 2022). A total of 819 academic staff (40% of the population) reported experiencing either health problems, work environment problems or both during the previous seven days. The prevalence of health problems only or a combination of work environment and health problems was higher among women than men (p-value ?0.05). This was especially the case for younger women, those in lower academic positions and those who had worked for fewer years at their current workplace. No difference was found for work environment problems. The majority of the employees who reported problems said that these problems affected their ability to perform at work (84-99%). The average production loss varied between 31 and 42% depending on the type of problem. Production loss due to health-related and work-environment related problems was highest among junior researchers and managers. No significant difference between men and women was found in the level of production loss. CONCLUSION: Subjective production loss in academia can be associated with health and work- environment problems. These losses appear similar for women and men even though younger female academics, women in lower academic ranks and those with fewer years of employment in their current workplace report a higher prevalence of health problems and combined work-environment and health problems than men. PMID- 29444652 TI - Physical activity and risk of testicular cancer: a systematic review. AB - BACKGROUND: Physical activity has been implicated as a risk factor in the development of testicular cancer (TC), but the relationship remains controversial. This systematic review pooled available evidence regarding this association. METHODS: Using Boolean search terms and following PRISMA guidelines, we examined the risk of TC across three categories of exposure: intensity (i.e. comparison of risk between those previously exposed to high, moderate and low levels of physical activity); dose-response (i.e. whether risk of TC increases or decreases with increasing exposure to physical activity); and the role of timing of physical activity (i.e. during early childhood or adolescence). RESULTS: Thirteen studies (11 case-control studies, 2 cohort studies) were included in the review. While some studies have reported a strong protective effect of high levels of physical activity on risk of TC, others have reported either no relationship or a weak direct association; and while a dose-response relationship has been identified across several studies, this relationship has been observed in both directions. Similarly conflicting results exist in terms of individual types of activity and the lifecourse timing of the physical activity. Reasons for this inconsistency may include the absence of any association, heterogeneous assessment of physical activity, misclassification bias and difference in sample sizes. CONCLUSIONS: On balance, there is presently no strong evidence of an association between physical activity and risk of subsequent TC. This review highlights key areas for future investigation that may clarify any association between physical activity and risk of testicular cancer. PMID- 29444653 TI - Transarterial chemoembolization (TACE) using mitomycin and lipiodol with or without degradable starch microspheres for hepatocellular carcinoma: comparative study. AB - BACKGROUND: To evaluate survival data and local tumor control after transarterial chemoembolization in two groups with different embolization protocols for the treatment of HCC patients. METHODS: Ninty-nine patients (mean age: 63.6 years), 78 male (78.8%) with HCC were repeatedly treated with chemoembolization in 4-week intervals. Eighty-eight patients had BCLC-Stage-B and in 11 patients, chemoembolization was performed for bridging (BCLC-Stage-A). In total, 667 chemoembolization treatments were performed (mean 6.7 treatments/patient). The administered chemotherapeutic agent included mitomycin. For embolization, lipiodol only (n = 51;51.5%; mean age 63.8 years; 38 male), or lipiodol plus degradable starch microspheres (DSM) (n = 48; 48.5%; mean age 63.4 years; 40 male) were used. The local tumor response was assessed by MRI using Response Evaluation Criteria in Solid Tumors 1.1 (RECIST 1.1). Patient survival times were evaluated using Kaplan-Meier curves and log-rank tests. RESULTS: The local tumor control in the lipiodol-group was: PR (partial response) in 11 (21.6%), SD (stable disease) in 32 (62.7%) and PD (progressive disease) in 8 cases (15.7%). In the lipiodol-DSM-group, PR was seen in 14 (29.2%), SD in 22 (45.8%), and PD in 12 (25.0%) individuals (p = 0.211). The median survival of patients after chemoembolization with lipiodol was 25 months and in the lipiodol-DSM-group 28 months (p = 0.845). CONCLUSION: Our data suggest a slight benefit of the use of lipiodol and DSM in comparison of using lipiodol only for chemoembolization of HCC in terms of local tumor control and survival data, this trend did not reach the level of significance. PMID- 29444654 TI - The comparison of perceived health-related quality of life between Australian children with severe specific language impairment to age and gender-matched peers. AB - BACKGROUND: Children with specific language impairment often present with multiple comorbidities, which may adversely affect both participation in play and academic performance, potentially impacting a child's health-related quality of life. This study 1) explored the suitability of the Pediatric Quality of Life InventoryTM Version 4.0 Generic Core Scales (PedsQLTM) for use with a typically developing Australian control group, and 2) compared the health-related quality of life between a control group and Australian children with severe specific language impairment. METHODS: Health-related quality of life data collected as part of a broader study of 43 children with severe specific language impairment (males = 35, age range 5-16, mean age = 8.79+/- 2.92) enrolled at a special school were used to explore previously unreported findings. Typically developing gender and age matched (+/- 3 months) peers were recruited from local schools. The PedsQLTM child self-report and proxy-report were individually or interviewer administered to the control group as required, and then compared to the group with specific language impairment. RESULTS: The PedsQLTM was reliable and feasible for use with the control group (N = 43, males = 35, age range = 5-16 years, mean age = 8.74+/- 2.94 years). Control group performance was as expected as per the manual. Parents of the control group scored their children significantly higher than did the children themselves on all scales except the emotional functioning scale. Both the control group children and their parents scored themselves significantly higher on all scales, compared to children with severe specific language impairment and their parents. CONCLUSIONS: The PedsQLTM was suitable for use with the control group. Further, the recruitment of a control group provided additional clarity on the extent a severe specific language impairment impacts on an Australian child's perceived health-related quality of life, compared to the manual cut-off scores. Severe specific language impairment significantly impacts negatively on the health-related quality of life of Australian children across all domains, particularly when compared to an age and gender-matched group of peers. These results warrant the inclusion of health related quality of life evaluations in the assessment of these children along with a multidisciplinary approach. PMID- 29444655 TI - A systematic study on the prevention and treatment of retinopathy of prematurity in China. AB - BACKGROUND: To identify the prevention situation, the main factors influencing prevention effects and to develop control measures over retinopathy of prematurity in China. METHODS: Using stratified random sampling method, we randomly selected 23 provincial and ministerial hospitals (8 in Guangdong province, 5 in Hunan province and 10 in Shaanxi province), 81 municipal hospitals (38 in Guangdong province, 19 in Hunan province and 24 in Shaanxi province), 180 district and county hospitals (76 in Guangdong province, 57 in Hunan province and 47 in Shaanxi province) in China. A total of 284 hospitals were enrolled in the study, with questionnaires distributed investigating the status and constrain factors of ROP presentation. Significant outcomes were analyzed thereafter by SPSS 19.0. RESULTS: The screening rate of ROP in medical institutions from eastern, central and western China were 84.6%, 35.0% and 56.7%, respectively. The screening rate of tertiary and secondary medical institutions were 84.6% and 25.7% in the eastern, 35.0% and 4.9% in the central, 56.7% and 5.9% in the western region. Screening was carried out better in the tertiary than that in the secondary and primary institutions. Treatment for ROP was available in 15.7% of all the tertiary hospitals surveyed. Lack of professionals, equipments and technologies were considered to be major restrain factors for screening. CONCLUSIONS: The ROP screening and treatment status have demonstrated significant regional diversity due to uneven distribution of medical resources in China. Developed areas had established intraregional cooperation models, whereas less developed areas should consider set up a large-scale, three-level ROP prevention network. It is of paramount importance that education and training towards ophthalmologists should be vigorously strengthened. It is strongly recommended that implement ROP telemedicine and integrated ROP prevention and management platforms through the Internet should be established. PMID- 29444656 TI - Implementation of a successful eradication protocol for Burkholderia Cepacia complex in cystic fibrosis patients. AB - BACKGROUND: Infection with Burkholderia cepacia complex (Bcc) results in a heterogeneous clinical course ranging from asymptomatic colonization of the airways to fulminant respiratory failure in patients with cystic fibrosis (CF). Early eradication of Pseudomonas aeruginosa improves clinical outcomes. The efficacy and clinical outcomes following implementation of an eradication protocol for Bcc are less well understood. METHODS: We developed and implemented a single center Bcc eradication protocol that included an intensive combination of intravenous, inhaled, and oral antibiotic therapies based on in vitro sensitivities. We conducted a retrospective cohort analysis of clinical outcomes compared to patients with chronic Bcc infection. RESULTS: Six patients were identified as having a newly acquired Bcc colonization and were placed on the eradication protocol. Sequential sputum samples after completion of the protocol demonstrated sustained clearance of Bcc in all patients. Lung function and nutritional status remained stable in the year following eradication. CONCLUSION: Clearance of Bcc from sputum cultures using a standardized protocol was successful at one year and was associated with clinical stability. PMID- 29444657 TI - Understanding the rapid increase in life expectancy in shanghai, China: a population-based retrospective analysis. AB - BACKGROUND: Life expectancy at birth (LE) is a comprehensive measure that accounts for age-specific death rates in a population. Shanghai has ranked first in LE in China mainland for decades. Understanding the reasons behind its sustained gain in LE provides a good reflection of many other cities in China. The aim of this study is intended to explore temporal trend in age- and cause specific gains in LE in Shanghai and the probable reasons lay behind. METHODS: Joinpoint regression was applied to evaluate temporal trend in LE and the long time span was then divided accordingly. Contributions to change in LE (1973-2015) were decomposed by age and cause at corresponding periods. RESULTS: LE in Shanghai could be divided into four phases ie., descent (1973-1976), recovery (1976-1998), rapid rise (1998-2004) and slow rise (2004-2015). The growing LE was mainly attributed to reductions in mortality from the elderly populations and chronic diseases such as cerebrovascular disease, chronic lower respiratory disease, and gastrointestinal cancers (stomach, liver and esophageal cancer). CONCLUSIONS: The four-decade sustained gain in LE in Shanghai is due to the reductions in mortality from the elderly and chronic diseases such as cerebrovascular disease, chronic lower respiratory disease, and gastrointestinal cancers. Further growth momentum still comes from the elderly population. PMID- 29444658 TI - Impact of tobacco control policies on adolescent smokeless tobacco and cigar use: a difference-in-differences approach. AB - BACKGROUND: While increasing cigarette taxes has been a major policy driver to decrease smoking, taxes on other tobacco products have received less attention. Our aims were to evaluate the impact of chewing tobacco/cigar taxes, cigarette taxes, and smoke-free legislation on adolescent male and female use of smokeless tobacco and cigars. METHODS: We analyzed data on 499,381 adolescents age 14-18 years from 36 US states in the Youth Risk Behavior Surveys (1999-2013) linked to state-level tobacco control policies. We conducted difference-in-differences regression models to assess whether changes in taxes and the enactment of smoke free legislation were associated with smokeless tobacco use and, separately, cigar use. Models were stratified by adolescent sex. RESULTS: We found that chewing tobacco taxes had no effect on smokeless tobacco use and cigar taxes had no effect on cigar use. In contrast, among males a 10% increase in cigarette taxes was associated with a 1.0 percentage point increase (0.0010, 95% CI 0.0003 0.0017) in smokeless tobacco use. A 10% increase in cigarette taxes was also associated with a 1.5 percentage point increase (0.0015, 95% CI 0.0006-0.0024) in cigar use among males and a 0.7 percentage point increase (0.0007, 95% CI 0.0001 0.0013) in cigar use among females. There was some evidence that smoke-free legislation was associated with an 1.1 percentage point increase (0.0105, 95% CI 0.0015-0.0194) in smokeless tobacco use among males only, but no effect of smoke free legislation on cigar use for males or females. CONCLUSIONS: Higher state cigarette taxes are associated with adolescents' use of cheaper, alternative tobacco products such as smokeless tobacco and cigars. Reducing tobacco use will require comprehensive tobacco control policies that are applied equally to and inclusive of all tobacco products. PMID- 29444659 TI - Right-to-left shunt and subclinical ischemic brain lesions in Chinese migraineurs: a multicentre MRI study. AB - BACKGROUND: Migraine is considered as a risk factor for subclinical brain ischemic lesions, and right-to-left shunt (RLS) is more common among migraineurs. This cross-sectional study assessed the association of RLS with the increased prevalence of subclinical ischemic brain lesions in migraineurs. METHODS: We enrolled 334 migraineurs from a multicentre study from June 2015 to August 2016. Participants were all evaluated using contrast-enhanced transcranial Doppler, magnetic resonance imaging (MRI), and completed a questionnaire covering demographics, the main risk factors of vascular disease, and migraine status. RLS was classified into four grades (Grade 0 = Negative; Grade I = 1 <= microbubbles (MBs) <= 10; Grade II = MBs > 10 and no curtain; Grade III = curtain). Silent brain ischemic infarctions (SBI) and white matter hyperintensities (WMHs) were evaluated on MRI. RESULTS: We found no significant differences between migraineurs with RLS and migraineurs without RLS in subclinical ischemic brain lesions.SBI and WMHs did not increase with the size of the RLS(p for trend for SBI = 0.066, p for trend for WMHs = 0.543). Furthermore, curtain RLS in migraineurs was a risk factor for the presence of SBI (p = 0.032, OR = 3.47; 95%CI: 1.12-10.76). There was no association between RLS and the presence of WMHs. CONCLUSION: Overall, RLS is not associated with increased SBI or WMHs in migraineurs. However, when RLS is present as a curtain pattern, it is likely to be a risk factor for SBIs in migraineurs. TRIAL REGISTRATION: No. NCT02425696 ; registered on April 21, 2015. PMID- 29444661 TI - RNA-QC-chain: comprehensive and fast quality control for RNA-Seq data. AB - BACKGROUND: RNA-Seq has become one of the most widely used applications based on next-generation sequencing technology. However, raw RNA-Seq data may have quality issues, which can significantly distort analytical results and lead to erroneous conclusions. Therefore, the raw data must be subjected to vigorous quality control (QC) procedures before downstream analysis. Currently, an accurate and complete QC of RNA-Seq data requires of a suite of different QC tools used consecutively, which is inefficient in terms of usability, running time, file usage, and interpretability of the results. RESULTS: We developed a comprehensive, fast and easy-to-use QC pipeline for RNA-Seq data, RNA-QC-Chain, which involves three steps: (1) sequencing-quality assessment and trimming; (2) internal (ribosomal RNAs) and external (reads from foreign species) contamination filtering; (3) alignment statistics reporting (such as read number, alignment coverage, sequencing depth and pair-end read mapping information). This package was developed based on our previously reported tool for general QC of next generation sequencing (NGS) data called QC-Chain, with extensions specifically designed for RNA-Seq data. It has several features that are not available yet in other QC tools for RNA-Seq data, such as RNA sequence trimming, automatic rRNA detection and automatic contaminating species identification. The three QC steps can run either sequentially or independently, enabling RNA-QC-Chain as a comprehensive package with high flexibility and usability. Moreover, parallel computing and optimizations are embedded in most of the QC procedures, providing a superior efficiency. The performance of RNA-QC-Chain has been evaluated with different types of datasets, including an in-house sequencing data, a semi simulated data, and two real datasets downloaded from public database.

CONCLUSIONS: We present here a tool, RNA-QC-Chain, which can be used to comprehensively resolve the quality control processes of RNA-Seq data effectively and efficiently. PMID- 29444660 TI - Volunteers in Ethiopia's women's development army are more deprived and distressed than their neighbors: cross-sectional survey data from rural Ethiopia. AB - BACKGROUND: Many Community Health Workers (CHWs) experience the same socioeconomic and health needs as their neighbors, given that they are by definition part of their communities. Yet very few studies aim to measure and characterize experiences of deprivation, poverty, and wellbeing among community health workers. This study quantitatively examines deprivation and wellbeing in Ethiopia's Women's Development Army (WDA), a massive unpaid community health workforce intended to improve population health and modernize the country. METHODS: We conducted a survey of 422 volunteer WDA leaders and community members in rural Amhara state, part of a mixed-methods ethnographic study of the experiences of women in the WDA. The survey asked a variety of questions about respondents' demographics, education, assets, and access to government services. We also used survey measures to evaluate respondents' levels of household food and water security, stressful life events, social support, work burden, and psychological distress. RESULTS: Volunteer WDA leaders and community members alike tend to have very low levels of schooling and household assets, and to be heavily burdened with daily work in several domains. Large proportions are food and water insecure, many are in debt, and many experience stretches of time with no money at all. Our survey also revealed differences between volunteer WDA leaders and other women that warrant attention. Leaders are less likely to be married and more likely to be divorced or separated. Leaders are also more likely to experience some aspects of food insecurity and report greater levels of psychological distress and more stressful life events. They also report slightly less social support than other women. CONCLUSIONS: In rural Amhara, women who seek out and/or are sought and recruited for leader roles in the WDA are a population living in precarity. In several domains, they experience even more hardship than their neighbors. These findings highlight a need for careful attention and further research into processes of volunteer CHW selection, and to determine whether or not volunteering for CHW programs increases socioeconomic and health risks among volunteers. CHW programs in settings of poverty should stop using unpaid labor and seek to create more paid CHW jobs. PMID- 29444663 TI - Gender-related differences in cardiometabolic risk factors and lifestyle behaviors in treatment-seeking adolescents with severe obesity. AB - BACKGROUND: Obesity during adolescence is associated with cardiovascular mortality in adulthood. The adverse obesity-related cardiometabolic risk profile is already observed in adolescence. We aimed to examine possible gender differences in cardiometabolic risk factors and lifestyle behaviors among adolescents with severe obesity, hypothesizing that boys would have both a higher prevalence of the metabolic syndrome as well as less healthy lifestyle behaviors than girls. METHODS: Cross-sectional study of treatment-seeking adolescents with severe obesity who attended the Morbid Obesity Centre at Vestfold Hospital Trust and who were consecutively enrolled in the Vestfold Register of Obese Children between September 2009 and September 2015. A total of 313 adolescents aged 12 to 18 years were recruited, whereof 268 subjects (49% boys) completed a food and activity frequency questionnaire and were included in the analysis. RESULTS: Mean (SD) age, BMI and BMI SDS were 15 (1.6) years, 38.6 (5.9) kg/m2 and 3.5 (0.6). Levels of LDL cholesterol, fasting insulin and glucose and diastolic blood pressure (DBP) did not differ between genders. Compared to girls, boys had significantly higher triglycerides (p = 0.037) and systolic blood pressure (SBP) (p = 0.003), as well as lower HDL cholesterol (p = 0.002). The metabolic syndrome was present in 27% of the boys and 19% of the girls (p = 0.140), and the prevalence of high DBP, dyslipidemia and dysglycemia also did not differ significantly between genders. The prevalence of high SBP was higher in boys than in girls (19% vs. 9%, p = 0.021). Gender was associated with a number of lifestyle habits, as a larger proportions of boys had higher screen time (p = 0.032), more regular breakfast eating (p = 0.023), higher intake of sugar sweetened soda (p = 0.036), and lower intake of vegetables than girls (p = 0.011). By contrast, physical activity level and intake of fruit and berries did not differ between genders. CONCLUSIONS: Male treatment-seeking adolescents with severe obesity had a more unfavorable set of metabolic and behavioral risk factors for cardiovascular disease than girls. Our results indicate that lifestyle behavioral markers should be thoroughly assessed in both genders, and possible gender-related differences in risk profile should be taken into account in future treatment programs. PMID- 29444662 TI - A systematic approach to RNA-associated motif discovery. AB - BACKGROUND: Sequencing-based large screening of RNA-protein and RNA-RNA interactions has enabled the mechanistic study of post-transcriptional RNA processing and sorting, including exosome-mediated RNA secretion. The downstream analysis of RNA binding sites has encouraged the investigation of novel sequence motifs, which resulted in exceptional new challenges for identifying motifs from very short sequences (e.g., small non-coding RNAs or truncated messenger RNAs), where conventional methods tend to be ineffective. To address these challenges, we propose a novel motif-finding method and validate it on a wide range of RNA applications. RESULTS: We first perform motif analysis on microRNAs and longer RNA fragments from various cellular and exosomal sources, and then validate our prediction through literature search and experimental test. For example, a 4 bp long motif, GUUG, was detected to be responsible for microRNA loading in exosomes involved in human colon cancer (SW620). Additional performance comparisons in various case studies have shown that this new approach outperforms several existing state-of-the-art methods in detecting motifs with exceptional high coverage and explicitness. CONCLUSIONS: In this work, we have demonstrated the promising performance of a new motif discovery approach that is particularly effective in current RNA applications. Important discoveries resulting from this work include the identification of possible RNA-loading motifs in a variety of exosomes, as well as novel insights in sequence features of RNA cargos, i.e., short non-coding RNAs and messenger RNAs may share similar loading mechanism into exosomes. This method has been implemented and deployed as a new webserver named MDS2 which is accessible at http://sbbi-panda.unl.edu/MDS2/ , along with a standalone package available for download at https://github.com/sbbi/MDS2 . PMID- 29444665 TI - Comparison of 1-year outcomes after Ahmed glaucoma valve implantation with and without Ologen adjuvant. AB - BACKGROUND: Many studies have investigated the clinical benefits of Ologen for trabeculectomy. However, its benefits for Ahmed glaucoma valve (AGV) implantation have not been investigated as extensively. The aim of this study was to compare the 1-year outcomes of AGV implantation with and without Ologen adjuvant for the treatment of refractory glaucoma. METHODS: This retrospective study included a total of 20 eyes of 20 glaucoma patients, who were followed for at least 1-year after undergoing AGV implantation. In 12 eyes of 12 patients, conventional AGV (CAGV) surgery was performed, while in 8 eyes of 8 patients, Ologen-augmented AGV (OAGV) implantation was performed. The outcomes were evaluated according to intraocular pressure (IOP) and the number of IOP-lowering medications. Complete success was defined as IOP <= 21 mmHg without medications throughout the 1-year follow-up period, and qualified success was defined as IOP <= 21 mmHg with or without medications throughout the 1-year follow-up period. RESULTS: The rate of complete success was significantly higher in the OAGV group (50.0%) than in the CAGV group (8.3%) (p = 0.035). There were no significant differences between the two groups in terms of qualified success or incidence of the early hypertensive phase. The IOP changes were similar between the groups within 1-year postoperatively, though the number of IOP-lowering medications was significantly lower in the OAGV group during the early hypertensive phase (p = 0.031, 0.031, and 0.025 at postoperative months 1, 2, and 3, respectively). When subjects were divided into groups according to the occurrence of the early hypertensive phase, the group with early hypertensive phase was more likely to use IOP-lowering medications at postoperative 6 months and 1 year (p = 0.002 and 0.005, respectively). CONCLUSIONS: OAGV surgery shows encouraging results for patients with refractory glaucoma, specifically with respect to the achievement of complete success and the reduction of the number of IOP-lowering medications during the early hypertensive phase. Furthermore, our results suggest that occurrence of the early hypertensive phase is predictive of which patients will require IOP-lowering medications at postoperative 6 months and 1 year. PMID- 29444664 TI - The knitting community-based trial for older women with osteoarthritis of the hands: design and rationale of a randomized controlled trial. AB - BACKGROUND: The prevalence of hand osteoarthritis (HOA) has been reported to be higher amongst women over 50 years old (66%) compared to men of the same age (34%). Although exercise therapy has been shown effective in reducing symptoms and disability associated with HOA, adherence to treatment programs remains low. The primary objective of this RCT is to examine the effectiveness of a 12-week knitting program for morning stiffness (primary outcome) and pain relief (secondary outcome) 2 h post-wakening in females (aged 50 to 85 years old) with mild to moderate hand osteoarthritis (HOA). METHODS/DESIGN: A single-blind, two arm randomized controlled trial (RCT) with a parallel group design will be used to reach this objective and compare results to a control group receiving an educational pamphlet on osteoarththritis (OA) designed by the Arthritis Society. The premise behind the knitting program is to use a meaningful occupation as the main component of an exercise program. The knitting program will include two components: 1) bi-weekly 20-min knitting sessions at a senior's club and 2) 20 min home daily knitting sessions for the five remaining weekdays. Participants assigned to the control group will be encouraged to read the educational pamphlet and continue with usual routine. Pain, morning stiffness, hand function, self efficacy and quality of life will be measured at baseline, six weeks, 12 weeks (end of program) with standardized tools. We hypothesize that participants in the knitting program will have significant improvements in all clinical outcomes compared to the control group. A published case study as well as the preliminary results of a feasibility study as examined through a 6-week pre-post study (n = 5 women with HOA) involving 20-min daily knitting morning sessions led to this proposed randomized controlled trial research protocol. This article describes the intervention, the empirical evidence to support it. DISCUSSION: This knitting RCT has the potential to enhance our understanding of the daily HOA symptoms control and exercise adherence, refine functional exercise recommendations in this prevalent disease, and reduce the burden of disability in older women.

AB - BACKGROUND: The number of revision Total Knee Arthroplasty (TKA) is rising in many countries. The aim of this study was the prospective assessment of the underlying causes leading to revision TKA in a tertiary care hospital and the comparison of those reasons with previously published data. METHODS: In this study patients who had revision TKA between 2010 and 2015 were prospectively included. Revision causes were categorized using all available information from patients' records including preoperative diagnostics, intraoperative findings as well as the results of the periprosthetic tissue analysis. According to previous studies patients were divided into early (up to 2 years) and late revision (more than 2 years). Additional also re-revisions after already performed revision TKA were included. RESULTS: We assessed 312 patients who underwent 402 revision TKA, 89.6% of them were referred to our center for revision surgery. In 289 patients (71.9%) this was the first revision surgery after primary TKA. Among the first revisions the majority was late revisions (73.7%). One hundred thirteen patients (28.1%) had already had one or more revision surgeries before. Overall, the most frequent reason for revision was infection (36.1%) followed by aseptic loosening (21.9%) and periprosthetic fracture (13.7%). CONCLUSIONS: In a specialized arthroplasty center periprosthetic joint infection (PJI) was the most common reason for revision and re-revision TKA. This is in contrast to population-based registry data and has consequences on costs as well as on success rates in such centers. PMID- 29444667 TI - In vitro antileishmanial and cytotoxicity activities of essential oils from Haplophyllum tuberculatum A. Juss leaves, stems and aerial parts. AB - BACKGROUND: Plants used for traditional medicine produce diverse and complex secondary metabolites exhibiting various medicinal properties. The medicinal plant Haplophyllum tuberculatum is used by native people against malaria and parasitic infections. METHODS: In this study and in order to contribute for the search of new natural drugs for leishmaniasis, the essential oils of H. tuberculatum leaves, stems and aerial parts (leaves+stems) collected in two different periods, 2013 and 2015, and their components by GC/FID and GC/MS analyses were investigated. Those collected in 2013 were also re-analyzed two years later. The extracted oils were screened in vitro for anti-leishmanial activity on Leishmania mexicana mexicana (L.m.m.) promastigotes and cytotoxicity on the Chinese Hamster Ovary (CHO) cell line. Limonene (1.5 - 8%), its isomers (R (+)-limonene and S-(-)-limonene), linalool and octanol were also tested. RESULTS: Results showed that the chemical composition varied according to the year of collection. Though major compounds remain almost the same, qualitative and quantitative variations in the composition of the EOs can be observed between the two years of collection, with some minor compounds identified only in one type of samples. Variation in the composition were also observed in the re analyzed volatile oils, showing stability concerns. The essential oils and R-(+) limonene showed moderate anti-leishmanial activity. Their IC50 range from 6.48 to 50.28 MUg/ml. Cytotoxicity assays for theses volatile extracts, R- (+)-limonene and S- (-)-limonene on CHO cells showed relatively potent cytotoxicity with a selectivity index <10. Their CC50 range from 27.79 to 82.56 MUg/ml. CONCLUSIONS: The findings of the present study demonstrated that H. tuberculatum might not be considered as a natural source for production of new anti-leishmanial agents without further analyzing its eventual in vivo toxicity as well as that of major pure compounds. PMID- 29444669 TI - Effects of multilevel posterior ligament dissection after spinal instrumentation on adjacent segment biomechanics as a potential risk factor for proximal junctional kyphosis: a biomechanical study. AB - BACKGROUND: Spinous processes and posterior ligaments, such as inter- and supraspinous ligaments are often sacrificed either deliberately to harvest osseous material for final spondylodesis e.g. in deformity corrective surgery or accidentally after posterior spinal instrumentation. This biomechanical study evaluates the potential destabilizing effect of a progressive dissection of the posterior ligaments (PL) after instrumented spinal fusion as a potential risk factor for proximal junctional kyphosis (PJK). METHODS: Twelve calf lumbar spines were instrumented from L3 to L6 (L3 = upper instrumented vertebra, UIV) and randomly assigned to one of the two study groups (dissection vs. control group). The specimens in the dissection group underwent progressive PL dissection, followed by cyclic flexion motion (250 cycles, moment: + 2.5 to + 20.0 Nm) to simulate physical activity and range of motion (ROM) testing of each segment with pure moments of +/-15.0 Nm after each dissection step. The segmental ROM in flexion and extension was measured. The control group underwent the same loading and ROM testing protocol, but without PL dissection. RESULTS: In the treatment group, the normalized mean ROM at L2-L3 (direct adjacent segment of interest, UIV/UIV + 1, PJK-level) increased to 104.7%, 107.3%, and 119.4% after dissection of the PL L4-L6, L3-L6, and L2-L6, respectively. In the control group the mean ROM increased only to 103.2%, 106.7%, and 108.7%. The ROM difference at L2-L3 with regard to the last dissection of the PL was statistically significant (P = 0.017) and a PL dissection in the instrumented segments showed a positive trend towards an increased ROM at UIV/UIV + 1. CONCLUSIONS: A dissection of the PL at UIV/UIV + 1 leads to a significant increase in ROM at this level which can be considered to be a risk factor for PJK and should be definitely avoided during surgery. However, a dissection of the posterior ligaments within the instrumented segments while preserving the ligaments at UIV/UIV + 1 leads to a slight but not significant increase in ROM in the adjacent cranial segment UIV/UIV + 1 in the used experimental setup. Using this experimental setup we could not confirm our initial hypothesis that the posterior ligaments within a long posterior instrumentation should be preserved. PMID- 29444670 TI - Breast cancer in Ethiopia: evidence for geographic difference in the distribution of molecular subtypes in Africa. AB - BACKGROUND: Breast cancer is a heterogeneous disease with several morphological and molecular subtypes. Widely accepted molecular classification system uses assessment of estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2) and proliferation marker Ki67. Few studies have been conducted on the incidence and molecular types of breast cancer in Sub Saharan Africa. Previous studies mainly from Western and Central Africa, showed breast cancer to occur at younger ages and to present with aggressive features, such as high-grade, advanced stage and triple-negative phenotype (negative for ER, PR and HER2). Limited data from East Africa including Ethiopia however shows hormone receptor negative tumors to account for a lower proportion of all breast cancers than has been reported from elsewhere in Africa. METHODS: In this study from Tikur Anbessa Specialized Hospital, 114 breast cancer patients diagnosed between 2012 and 2015 were enrolled. ER, PR, Ki67 and HER2 receptor status were assessed using immunohistochemistry from tissue microarrays. FISH was used for assessment of gene amplification in all equivocal tumor samples and for confirmation in HER2-enriched cases. RESULTS: The distribution of molecular subtypes was: Luminal A: 40%; Luminal B: 26%; HER2-enriched: 10%; TNBC: 23%. ER were positive in 65% of all tumors and 43% the cases were positive for PR. There was statistically significant difference in median age at diagnosis between the molecular subtypes (P < 0.05). There was a bimodal distribution of molecular subtypes in different age ranges with Luminal B subtype being more common at younger ages (median = 36) and Luminal A subtype more prevalent at older ages (median = 42). There were no statistically significant differences in tumor grade, histology, and stage between the molecular subtypes of breast cancer. CONCLUSION: The present study detected Luminal A breast cancer to be the most common subtype and reveals a relatively low rate of hormone receptor negative and TNBC. Our findings and results from other East African studies suggest geographic variability in the distribution of the molecular subtypes of breast cancer in Africa and hence have important clinical and policy implications for breast cancer control and treatment in Ethiopia. PMID- 29444668 TI - Gigantol inhibits Wnt/beta-catenin signaling and exhibits anticancer activity in breast cancer cells. AB - BACKGROUND: Gigantol is a bibenzyl compound derived from several medicinal orchids. This biologically active compound has been shown to have promising therapeutic potential against cancer cells, but its mechanism of action remains unclear. METHODS: The inhibitory effect of gigantol on Wnt/beta-catenin signaling was evaluated with the SuperTOPFlash reporter system. The levels of phosphorylated low-density lipoprotein receptor related protein 6 (LRP6), total LRP6 and cytosolic beta-catenin were determined by Western blot analysis. The expression of Wnt target genes was analyzed using real-time PCR. Cell viability was measured with a MTT assay. The effect of gigantol on cell migration was examined using scratch wound-healing and transwell migration assays. RESULTS: Gigantol decreased the level of phosphorylated LRP6 and cytosolic beta-catenin in HEK293 cells. In breast cancer MDA-MB-231 and MDA-MB-468 cells, treatment with gigantol reduced the level of phosphorylated LRP6, total LRP6 and cytosolic beta catenin in a dose-dependent manner, resulting in a decrease in the expression of Wnt target genes Axin2 and Survivin. We further demonstrated that gigantol suppressed the viability and migratory capacity of breast cancer cells. CONCLUSION: Gigantol is a novel inhibitor of the Wnt/beta-catenin pathway. It inhibits Wnt/beta-catenin signaling through downregulation of phosphorylated LRP6 and cytosolic beta-catenin in breast cancer cells. PMID- 29444671 TI - Tailoring an educational program on the AHRQ Patient Safety Indicators to meet stakeholder needs: lessons learned in the VA. AB - BACKGROUND: Given that patient safety measures are increasingly used for public reporting and pay-for performance, it is important for stakeholders to understand how to use these measures for improvement. The Agency for Healthcare Research and Quality (AHRQ) Patient Safety Indicators (PSIs) are one particularly visible set of measures that are now used primarily for public reporting and pay-for performance among both private sector and Veterans Health Administration (VA) hospitals. This trend generates a strong need for stakeholders to understand how to interpret and use the PSIs for quality improvement (QI). The goal of this study was to develop an educational program and tailor it to stakeholders' needs. In this paper, we share what we learned from this program development process. METHODS: Our study population included key VA stakeholders involved in reviewing performance reports and prioritizing and initiating quality/safety initiatives. A pre-program formative evaluation through telephone interviews and web-based surveys assessed stakeholders' educational needs/interests. Findings from the formative evaluation led to development and implementation of a cyberseminar based program, which we tailored to stakeholders' needs/interests. A post-program survey evaluated program participants' perceptions about the PSI educational program. RESULTS: Interview data confirmed that the concepts we had developed for the interviews could be used for the survey. Survey results informed us on what program delivery mode and content topics were of high interest. Six cyberseminars were developed-three of which focused on two content areas that were noted of greatest interest: learning how to use PSIs for monitoring trends and understanding how to interpret PSIs. We also used snapshots of VA PSI reports so that participants could directly apply learnings. Although initial interest in the program was high, actual attendance was low. However, post-program survey results indicated that perceptions about the program were positive. CONCLUSIONS: Conducting a formative evaluation was a highly important process in program development. The useful information that we collected through the interviews and surveys allowed us to tailor the program to stakeholders' needs and interests. Our experiences, particularly with the formative evaluation process, yielded valuable lessons that can guide others when developing and implementing similar educational programs. PMID- 29444672 TI - Adherence to Mediterranean and low-fat diets among heart and lung transplant recipients: a randomized feasibility study. AB - BACKGROUND: Heart and lung transplant recipients are at a substantially increased risk of cardiovascular disease (CVD). Since both low-fat and Mediterranean diets can reduce CVD in immunocompetent people at high risk, we assessed adherence among thoracic transplant recipients allocated to one or other of these diets for 12 months. METHODS: Forty-one transplant recipients (20 heart; 21 lung) randomized to a Mediterranean or a low-fat diet for 12 months received diet specific education at baseline. Adherence was primarily assessed by questionnaire: 14-point Mediterranean diet (score 0-14) and 9-point low-fat diet (score 0-16) respectively, high scores indicating greater adherence. Median scores at baseline, 6 months, 12 months, and 6-weeks post-intervention were compared by dietary group. We further assessed changes in weight, body mass index (BMI) and serum triglycerides from baseline to 12 months as an additional indicator of adherence. RESULTS: In those randomized to a Mediterranean diet, median scores increased from 4 (range 1-9) at baseline, to 10 (range 6-14) at 6 months and were maintained at 12 months, and also at 6-weeks post-intervention (median 10, range 6-14). Body weight, BMI and serum triglycerides decreased over the 12-month intervention period (mean weight - 1.8 kg, BMI -0.5 kg/m2, triglycerides - 0.17 mmol/L). In the low-fat diet group, median scores were 11 (range 9-14) at baseline; slightly increased to 12 (range 9-16) at 6 months, and maintained at 12 months and 6 weeks post-intervention (median 12, range 8-15). Mean changes in weight, BMI and triglycerides were - 0.2 kg, 0.0 kg/m2 and - 0.44 mmol/L, respectively. CONCLUSIONS: Thoracic transplant recipients adhered to Mediterranean and low-fat dietary interventions. The change from baseline eating habits was notable at 6 months; and this change was maintained at 12 months and 6 weeks post-intervention in both Mediterranean diet and low-fat diet groups. Dietary interventions based on comprehensive, well-supported education sessions targeted to both patients and their family members are crucial to success. Such nutritional strategies can help in the management of their substantial CVD risk. TRIAL REGISTRATION: The IRAS trial registry ( ISRCTN63500150 ). Date of registration 27 July 2016. Retrospectively registered. PMID- 29444673 TI - Effect of tt-farnesol and myricetin on in vitro biofilm formed by Streptococcus mutans and Candida albicans. AB - BACKGROUND: Dental caries is considered a multifactorial disease, in which microorganisms play an important role. The diet is decisive in the biofilm formation because it provides the necessary resources for cellular growth and exopolysaccharides synthesis. Exopolysaccharides are the main components of the extracellular matrix (ECM). The ECM provides a 3D structure, support for the microorganisms and form diffusion-limited environments (acidic niches) that cause demineralization of the dental enamel. Streptococcus mutans is the main producer of exopolysaccharides. Candida albicans is detected together with S. mutans in biofilms associated with severe caries lesions. Thus, this study aimed to determine the effect of tt-farnesol and myricetin topical treatments on cariogenic biofilms formed by Streptococcus mutans and Candida albicans. METHODS: In vitro dual-species biofilms were grown on saliva-coated hydroxyapatite discs, using tryptone-yeast extract broth with 1% sucrose (37 degrees C, 5% CO2). Twice daily topical treatments were performed with: vehicle (ethanol 15%, negative control), 2 mM myricetin, 4 mM tt-farnesol, myricetin + tt-farnesol, myricetin + tt-farnesol + fluoride (250 ppm), fluoride, and chlorhexidine digluconate (0.12%; positive control). After 67 h, biofilms were evaluated to determine biofilm biomass, microbial population, and water-soluble and -insoluble exopolysaccharides in the ECM. RESULTS: Only the positive control yielded a reduced quantity of biomass and microbial population, while tt-farnesol treatment was the least efficient in reducing C. albicans population. The combination therapy myricetin + farnesol + fluoride significantly reduced water-soluble exopolysaccharides in the ECM (vs. negative control; p < 0.05; ANOVA one-way, followed by Tukey's test), similarly to the positive control. CONCLUSIONS: Therefore, the combination therapy negatively influenced an important virulence trait of cariogenic biofilms. However, the concentrations of both myricetin and tt-farnesol should be increased to produce a more pronounced effect to control these biofilms. PMID- 29444674 TI - The gendered experience with respect to health-seeking behaviour in an urban slum of Kolkata, India. AB - BACKGROUND: Empirical evidence shows that the relationship between health-seeking behaviour and diverse gender elements, such as gendered social status, social control, ideology, gender process, marital status and procreative status, changes across settings. Given the high relevance of social settings, this paper intends to explore how gender elements interact with health-seeking practices among men and women residing in an Indian urban slum, in consideration of the unique socio cultural context that characterises India's slums. METHODS: The study was conducted in Sahid Smriti Colony, a peri-urban slum of Kolkata, India. The referral technique was used for selecting participants, as people in the study area were not very comfortable in discussing their health issues and health seeking behaviours. The final sample included 66 participants, 34 men and 32 women. Data was collected through individual face-to-face in-depth interviews with a semi-structured questionnaire. RESULTS: The data analysis shows six categories of reasons underlying women's preferences for informal healers, which are presented in the form of the following themes: cultural competency of care, easy communication, gender-induced affordability, avoidance of social stigma and labelling, living with the burden of cultural expectations and geographical and cognitive distance of formal health care. In case of men ease of access, quality of treatment and expected outcome of therapies are the three themes that emerged as the reasons behind their preferences for formal care. CONCLUSION: Our results suggest that both men and women utilise formal and informal care, but with different motives and expectations, leading to contrasting health-seeking outcomes. These gender-induced contrasts relate to a preference for socio cultural (women) versus technological (men) therapies and long (women) versus fast (men) treatment, and are linked to their different societal and familial roles. The role of women in following and maintaining socio-cultural norms leads them to focus on care that involves long discussions mixed with socio-cultural traits that help avoid economic and social sanctions, while the role of men as bread earners requires them to look for care that ensures a fast and complete recovery so as to avoid financial pressures. PMID- 29444675 TI - Current and future distribution of Aedes aegypti and Aedes albopictus (Diptera: Culicidae) in WHO Eastern Mediterranean Region. AB - BACKGROUND: Aedes-borne diseases as dengue, zika, chikungunya and yellow fever are an emerging problem worldwide, being transmitted by Aedes aegypti and Aedes albopictus. Lack of up to date information about the distribution of Aedes species hampers surveillance and control. Global databases have been compiled but these did not capture data in the WHO Eastern Mediterranean Region (EMR), and any models built using these datasets fail to identify highly suitable areas where one or both species may occur. The first objective of this study was therefore to update the existing Ae. aegypti (Linnaeus, 1762) and Ae. albopictus (Skuse, 1895) compendia and the second objective was to generate species distribution models targeted to the EMR. A final objective was to engage the WHO points of contacts within the region to provide feedback and hence validate all model outputs. METHODS: The Ae. aegypti and Ae. albopictus compendia provided by Kraemer et al. (Sci Data 2:150035, 2015; Dryad Digit Repos, 2015) were used as starting points. These datasets were extended with more recent species and disease data. In the next step, these sets were filtered using the Koppen-Geiger classification and the Mahalanobis distance. The occurrence data were supplemented with pseudo absence data as input to Random Forests. The resulting suitability and maximum risk of establishment maps were combined into hard-classified maps per country for expert validation. RESULTS: The EMR datasets consisted of 1995 presence locations for Ae. aegypti and 2868 presence locations for Ae. albopictus. The resulting suitability maps indicated that there exist areas with high suitability and/or maximum risk of establishment for these disease vectors in contrast with previous model output. Precipitation and host availability, expressed as population density and night-time lights, were the most important variables for Ae. aegypti. Host availability was the most important predictor in case of Ae. albopictus. Internal validation was assessed geographically. External validation showed high agreement between the predicted maps and the experts' extensive knowledge of the terrain. CONCLUSION: Maps of distribution and maximum risk of establishment were created for Ae. aegypti and Ae. albopictus for the WHO EMR. These region-specific maps highlighted data gaps and these gaps will be filled using targeted monitoring and surveillance. This will increase the awareness and preparedness of the different countries for Aedes borne diseases. PMID- 29444676 TI - Parameters influencing hand grip strength measured with the manugraphy system. AB - BACKGROUND: This study aimed to determine whether sex, hand length and the individual training status affect hand strength and whether these measurements differ if they are recorded using the Jamar dynamometer or a new cylindrical measuring system. METHODS: For this purpose, 152 healthy adults were examined using a new manugraphy measuring system (novel, Munich, Germany) comprising two measuring cylinders of different sizes and a Jamar electronic dynamometer with two grip positions corresponding approximately to the sizes of the cylinders. A descriptive analysis was performed as well as a correlation analysis using the Pearson correlation coefficient. To prepare predictive models, multiple linear regression analyses were carried out to determine factors that influence the force and p <= 0.05 was considered statistically significant. RESULTS: A significant difference in the maximum and mean strength was observed that is dependent on sex, with men stronger than women, in line with expectations, and hand length, with small hands able to exert less force than large hands. No consistent increase in strength could be attributed to repetitive manual loads applied either at work or in leisure activities. CONCLUSIONS: Both measurement techniques yielded similar results, suggesting that manugraphy is well suited for clinical research purposes because it not only takes measurements that are just as reproducible and valid as the conventional measurement technique but in doing so measures not just the total strength of a hand but also enables more precise comparisons of isolated hand regions applying dynamic measurements.

AB - BACKGROUND: Parkinson's disease (PD) is a progressive neurodegenerative disorder of the central nervous system. Although the causes of PD pathogenesis remain incomplete, some evidences has suggested that oxidative stress is an important mediator in its pathogenesis. The aim of this study was to evaluate the protective effects of seaweeds with high antioxidant activity on 6 hydroxydopamine (6-OHDA)-induced neurotoxicity in the human neuroblastoma cell line SH-SY5Y, as well as the associated intracellular signaling pathways. METHODS: Cell viability studies were assessed by 3-(4,5-dimethylthiazol-2yl)-2,5 diphenyltetrazolium (MTT) bromide assay and the intracellular signaling pathways analyzed were: hydrogen peroxide (H2O2) production, changes in the mitochondrial membrane potential and Caspase-3 activity. RESULTS: Exposure of SH-SY5Y cells to 6-OHDA (10-1000 MUM) reduced cell's viability in a concentration and time dependent manner. The data suggest that the cell death induced by 6-OHDA was mediated by an increase of H2O2 production, the depolarization of mitochondrial membrane potential and the increase of Caspase-3 activity. Extracts from S. polyshides, P. pavonica, S. muticum, C. tomentosum and U. compressa revealed to efficiently protect cell's viability in the presence of 6-OHDA (100 MUM; 24 h). These effects appear to be associated with the reduction of H2O2 cell's production, the protection of mitochondrial membrane's potential and the reduction of Caspase-3 activity. CONCLUSIONS: These results suggest that seaweeds can be a promising source of new compounds with neuroprotective potential. PMID- 29444678 TI - The wild taxa utilized as vegetables in Sicily (Italy): a traditional component of the Mediterranean diet. AB - BACKGROUND: Wild vegetables in the Mediterranean Basin are still often consumed as a part of the diet and, in particular, there is a great tradition regarding their use in Sicily. In this study, an ethnobotanical field investigation was carried out to (a) identify the wild native taxa traditionally gathered and consumed as vegetables in Sicily, comparing the collected ethnobotanical data with those of other countries that have nominated the Mediterranean diet for inclusion in the UNESCO Representative List of the Intangible Cultural Heritage of Humanity and (b) highlight new culinary uses of these plants. METHODS: Interviews were carried out in 187 towns and villages in Sicily between 2005 and 2015. A total of 980 people over the age of 50 were interviewed (mainly farmers, shepherds, and experts on local traditions). Plants recorded were usually collected in collaboration with the informants to confirm the correct identification of the plants. The frequencies of citation were calculated. RESULTS: Two hundred fifty-three taxa (specific and intraspecific) belonging to 39 families, and 128 genera were recorded (26 were cited for the first time). The most represented families were Asteraceae, Brassicaceae, Apiaceae, Amaryllidaceae, Malvaceae, and Polygonaceae. Only 14 taxa were cited by 75% of the people interviewed. The aerial parts of wild plants, including leaves, tender shoots, and basal rosettes, are the main portions collected, while the subterranean parts are used to a lesser extent. For some vegetables, more parts are utilized. Most of the reported vegetables are consumed cooked. In addition to the widely known vegetables (Borago officinalis, Beta spp., Cichorium spp., Brassica spp., Carduus spp., etc.), the so-called ancient vegetables are included (Onopordum illyricum, Centaurea calcitrapa, Nasturtium officinale, Scolymus spp., Smyrnium rotundifolium), and some unique uses were described. Comparing the Sicilian findings to those from other countries, a very high number of vegetable taxa were detected, 72 of which are eaten only in Sicily, while 12 are consumed in all the Mediterranean countries examined. CONCLUSIONS: The research shows a high level of Sicilian knowledge about using wild plants as a traditional food source. Wild vegetables are healthy and authentic ingredients for local and ancient recipes, which are fundamental to the revitalization of quality food strictly connected to traditional agroecosystems. PMID- 29444679 TI - Understanding perceived availability and importance of tobacco control interventions to inform European adoption of a UK economic model: a cross sectional study. AB - BACKGROUND: The evidence on the extent to which stakeholders in different European countries agree with availability and importance of tobacco-control interventions is limited. This study assessed and compared stakeholders' views from five European countries and compared the perceived ranking of interventions with evidence-based ranking using cost-effectiveness data. METHODS: An interview survey (face-to-face, by phone or Skype) was conducted between April and July 2014 with five categories of stakeholders - decision makers, service purchasers, service providers, evidence generators and health promotion advocates - from Germany, Hungary, the Netherlands, Spain, and the United Kingdom. A list of potential stakeholders drawn from the research team's contacts and snowballing served as the sampling frame. An email invitation was sent to all stakeholders in this list and recruitment was based on positive replies. Respondents were asked to rate availability and importance of 30 tobacco control interventions. Kappa coefficients assessed agreement of stakeholders' views. A mean importance score for each intervention was used to rank the interventions. This ranking was compared with the ranking based on cost-effectiveness data from a published review. RESULTS: Ninety-three stakeholders (55.7% response rate) completed the survey: 18.3% were from Germany, 17.2% from Hungary, 30.1% from the Netherlands, 19.4% from Spain, and 15.1% from the UK. Of those, 31.2% were decision makers, 26.9% evidence generators, 19.4% service providers, 15.1% health-promotion advocates, and 7.5% purchasers of services/pharmaceutical products. Smoking restrictions in public areas were rated as the most important intervention (mean score = 1.89). The agreement on availability of interventions between the stakeholders was very low (kappa = 0.098; 95% CI = [0.085, 0.111] but the agreement on the importance of the interventions was fair (kappa = 0.239; 95% CI = [0.208, 0.253]). A correlation was found between availability and importance rankings for stage-based interventions. The importance ranking was not statistically concordant with the ranking based on published cost-effectiveness data (Kendall rank correlation coefficient = 0.40; p-value = 0.11; 95% CI = [- 0.09, 0.89]). CONCLUSIONS: The intrinsic differences in stakeholder views must be addressed while transferring economic evidence Europe-wide. Strong engagement with stakeholders, focussing on better communication, has a potential to mitigate this challenge. PMID- 29444680 TI - Experiences from ten years of incident reporting in health care: a qualitative study among department managers and coordinators. AB - BACKGROUND: Incident reporting (IR) in health care has been advocated as a means to improve patient safety. The purpose of IR is to identify safety hazards and develop interventions to mitigate these hazards in order to reduce harm in health care. Using qualitative methods is a way to reveal how IR is used and perceived in health care practice. The aim of the present study was to explore the experiences of IR from two different perspectives, including heads of departments and IR coordinators, to better understand how they value the practice and their thoughts regarding future application. METHODS: Data collection was performed in Ostergotland County, Sweden, where an electronic IR system was implemented in 2004, and the authorities explicitly have advocated IR from that date. A purposive sample of nine heads of departments from three hospitals were interviewed, and two focus group discussions with IR coordinators took place. Data were analysed using qualitative content analysis. RESULTS: Two main themes emerged from the data: "Incident reporting has come to stay" building on the categories entitled perceived advantages, observed changes and value of the IR system, and "Remaining challenges in incident reporting" including the categories entitled need for action, encouraged learning, continuous culture improvement, IR system development and proper use of IR. CONCLUSIONS: After 10 years, the practice of IR is widely accepted in the selected setting. IR has helped to put patient safety on the agenda, and a cultural change towards no blame has been observed. The informants suggest an increased focus on action, and further development of the tools for reporting and handling incidents.

AB - Microalgae are simple chlorophyll containing organisms, they have high photosynthetic efficiency and can synthesize and accumulate large quantities of carbohydrate biomass. They can be cultivated in fresh water, seawater and wastewater. They have been used as feedstock for producing biodiesel, bioethanol and biogas. The production of these biofuels can be integrated with CO2 mitigation, wastewater treatment, and the production of high-value chemicals. Biohydrogen from microalgae is renewable. Microalgae have several advantages compared to terrestrial plants, such as higher growth rate with superior CO2 fixation capacity; they do not need arable land to grow; they do not contain lignin. In this review, the biology of microalgae and the chemical composition of microalgae were briefly introduced, the advantages and disadvantages of hydrogen production from microalgae were discussed, and the pretreatment of microalgal biomass and the fermentative hydrogen production from microalgal biomass pretreated by different methods (including physical, chemical, biological and combined methods) were summarized and evaluated. For the production of biohydrogen from microalgae, the economic feasibility remains the most important aspect to consider. Several technological and economic issues must be addressed to achieve success on a commercial scale. PMID- 29444682 TI - Serum IgG subclass levels and risk of exacerbations and hospitalizations in patients with COPD. AB - BACKGROUND: The literature is scarce regarding the prevalence and clinical impact of IgG subclass deficiency in COPD. We investigated the prevalence of IgG subclass deficiencies and their association with exacerbations and hospitalizations using subjects from two COPD cohorts. METHODS: We measured IgG subclass levels using immunonephelometry in serum samples from participants enrolled in two previous COPD trials: Macrolide Azithromycin for Prevention of Exacerbations of COPD (MACRO; n = 976) and Simvastatin for the Prevention of Exacerbations in Moderate-to-Severe COPD (STATCOPE; n = 653). All samples were collected from clinically stable participants upon entry into both studies. IgG subclass deficiency was diagnosed when IgG subclass levels were below their respective lower limit of normal: IgG1 < 2.8 g/L; IgG2 < 1.15 g/L; IgG3 < 0.24 g/L; and IgG4 < 0.052 g/L. To investigate the impact of IgG subclass levels on time to first exacerbation or hospitalization, we log-transformed IgG levels and performed Cox regression models, with adjustments for confounders. RESULTS: One or more IgG subclass deficiencies were found in 173 (17.7%) and 133 (20.4%) participants in MACRO and STATCOPE, respectively. Lower IgG1 or IgG2 levels resulted in increased risk of exacerbations with adjusted hazard ratios (HR) of 1.30 (95% CI, 1.10-1.54, p < 0.01) and 1.19 (95% CI, 1.05-1.35, p < 0.01), respectively in the MACRO study, with STATCOPE yielding similar results. Reduced IgG1 or IgG2 levels were also associated with increased risk of hospitalizations: the adjusted HR for IgG1 and IgG2 was 1.52 (95% CI: 1.15-2.02, p < 0.01) and 1.33 (95% CI, 1.08-1.64, p < 0.01), respectively for the MACRO study; in STATCOPE, only IgG2 was an independent predictor of hospitalization. In our multivariate Cox models, IgG3 and IgG4 levels did not result in significant associations for both outcomes in either MACRO or STATCOPE cohorts. CONCLUSIONS: Approximately 1 in 5 COPD patients had one or more IgG subclass deficiencies. Reduced IgG subclass levels were independent risk factors for both COPD exacerbations (IgG1 and IgG2) and hospitalizations (IgG2) in two COPD cohorts. TRIAL REGISTRATION: This study used serum samples from participants of the MACRO ( NCT00325897 ) and STATCOPE ( NCT01061671 ) trials. PMID- 29444683 TI - Potential effects of the combination of nicotinamide, vitamin B2 and vitamin C on oxidative-mediated hepatotoxicity induced by thioacetamide. AB - BACKGROUND: The liver disease is one of the most important traditional public health problems in Egypt. Oxidative stress is attributed to such pathological condition that further contributes to the initiation and progression of liver injury. In the present study, we have investigated if the strong antioxidant power of Nicotinamide (NA), Vitamin B2 (VB2), and Vitamin C (VC) can ameliorate TAA-induced oxidative stress-mediated liver injury in the rats. METHODS: Thirty six albino rats were divided into six groups: Control group; TAA group (IP injection with TAA at a dosage of 200 mg/Kg three times a week for two months); TAA + NA group (rats administered with NA at a dosage of 200 mg/kg daily besides TAA as in the control); TAA + VB2 group (rats administered with vitamin B2 at a dosage of 30 mg/kg daily besides injection with TAA); TAA + VC group (rats administered with vitamin C at a dosage of 200 mg/kg daily along with injection of TAA). TAA + NA + VB + VC group (rats administered the with the three vitamins daily in TAA pre-injected at the respective doses described above). RESULTS: Treatment of rats with TAA led to a significant elevation of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), total bilirubin, cholesterol, triglycerides, low-density lipoprotein (LDL) and tumor necrosis factor-alpha (TNF-alpha) in the serum samples. Moreover, malondialdehyde (MDA), hydroxyproline and nitic oxide (NO) were also significantly increased in the TAA-treated rats, while reduced glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT) were significantly compromised in the hepatic samples. Rats administered with NA, VB2, and VC as individually or in combination ameliorated the deleterious effects of TAA that was confirmed by histopathology. However, the combination of the three vitamins was found more effective as compared to each of the vitamins. CONCLUSION: Our work demonstrates that NA, VB2, and VC cross-talk with each other that act as a more potent biochemical chain of antioxidant defense against TAA induced toxicities in vivo. PMID- 29444684 TI - Medicinal plants used by traditional healers to treat malignancies and other human ailments in Dalle District, Sidama Zone, Ethiopia. AB - BACKGROUND: Medicinal plants (MPs) used by traditional healers (THs) were investigated in Megera and adjacent subdistricts (kebeles) of Dalle District, Sidama Zone, southern Ethiopia. The objective of the study was to identify and record MPs and their traditional uses in the treatment of various human ailments with emphasis on malignancies and other most frequently reported diseases. METHODS: Traditional medicinal knowledge held by 20 THs was investigated following standard ethnobotanical approaches. Guided field walk, free listing, rigorous individual interviews with extended discussions, and local market surveys were employed to obtain information. Preference rankings, paired comparisons, use value (UV) index, frequency of citation (FC), fidelity level (FL), and informant consensus factor (ICF) matrices were engaged to identify MPs used to treat malignancies and the other most prevalent human ailments. RESULTS: Seventy-one MP species belonging to 63 genera and 46 families, used to treat 39 human ailments, were recorded. A high proportion of the species recovered was shrubs (35.2%); while 64.7% were retrieved from the wild habitat. Leaves were the main part of the MPs used (42.9%), followed by fruits/seeds (13%); all preparations were made from fresh materials and about 27.9% involved boiling. The frequent route of delivery was oral (77.9%), followed by dermal (17.6%). About 40.8% of the MPs were used for treating two or more ailments. About 19.7% of the MPs were used to treat malignancies (ICF = 0.86) among which the plant species Sideroxylon oxyacanthum was the most frequently used (FL = 70%). The species Podocarpus falcatus and Hagenia abyssinica were preferred to treat jaundice and deworm in helminthiases, respectively. CONCLUSION: The study area is very rich in plant biodiversity, and the herbal medicine is an integral part of the traditional healthcare system. The MPs are exposed to various destructive anthropogenic activities, and this situation calls for integrated conservation measures. Furthermore, the rich ethnomedicinal knowledge held by the Sidama community at large and TM practitioners, in particular, needs an in-depth study and documentation. Investigations of the MPs with high ICF, FL, and UVs to malignancies, jaundice, and helminthiases could possibly contribute to future drug development efforts. PMID- 29444685 TI - Prevalence and correlates of HIV infection among men who inject drugs in a remote area of Vietnam. AB - BACKGROUND: Lack of information on the HIV epidemic among men who inject drugs (MWID) in northwestern Vietnam, a remote area, may hamper national efforts to control the disease. We examined HIV prevalence, needle-syringe sharing behaviors, and associated factors among MWID in three areas of northwestern Vietnam. METHODS: We used descriptive analysis to report the characteristics, frequency of risk behaviors, and of access to healthcare services among the MWID. Univariable logistic regression was used to assess the associations between the HIV infection, needle-syringe sharing behaviors, and their independent variables. We further explored these associations in multivariable analyses where we included independent variables based on a priori knowledge and their associations with the dependent variables determined in univariable analyses (p < 0.25). RESULTS: The HIV prevalence was 37.9, 16.9, and 18.5% for Tuan Giao, Bat Xat, and Lao Cai City, respectively, and 25.4% overall. MWID of Thai minority ethnicity were more likely to be HIV-positive (adjusted odds ratio (AOR) 3.55; 95% confidence interval (CI) 1.84-6.87). The rate of needle-syringe sharing in the previous 6 months was approximately 9% among the MWID in Tuan Giao and Lao Cai City, and 27.8% in Bat Xat. Two thirds of the participants never underwent HIV testing before this study. Ever having been tested for HIV before this study was not associated with any needle-syringe sharing behaviors. Among the HIV-positive MWID, those who received free clean needles and syringes were less likely to give used needles and syringes to peers (AOR 0.21; 95% CI 0.06-0.79). Going to a "hotspot" in the previous week was associated with increased odds of needle syringe sharing in multiple subgroups. CONCLUSION: Our findings on HIV prevalence and testing participation among a subset of MWID in the northwestern Vietnam were corroborated with trend analysis results from the most recent HIV/STI Integrated Biological and Behavioral Surveillance report (data last collected in 2013.) We provided important insights into these MWID's risky injection behaviors. We suggest heightened emphasis on HIV testing and needle and syringe provision for this population. Also, policymakers and program implementers should target hotspots as a main venue to tackle HIV epidemics. PMID- 29444686 TI - Cumulative incidence, distribution, and determinants of catastrophic health expenditure in Nepal: results from the living standards survey. AB - BACKGROUND: Nepal has committed to the global community to achieve universal health coverage by 2030. Nevertheless, Nepal still has a high proportion of out of-pocket health payment and a limited risk-pooling mechanism. Out-of-pocket payment for the healthcare services could result in catastrophic health expenditure (CHE). Evidence is required to effectively channel the efforts to lower those expenses in order to achieve universal health coverage. However, little is known about CHE and its determinants in a broad national context in Nepal. Therefore, this study was conducted to explore the cumulative incidence, distribution, and determinants of CHE in Nepal. METHODS: Data were obtained from the nationally representative survey, the Nepal Living Standards Survey-third undertaken in 2010/11. Information from 5988 households was used for the analyses. Households were classified as having CHE when their out-of-pocket health payment was greater than or equal to 40% of their capacity to pay. Remaining households were classified as not having CHE. Logistic regression analyses were used to identify determinants of CHE. RESULTS: Based on household weighted sample, the cumulative incidence of CHE was 10.3% per month in Nepal. This incidence was concentrated in the far-western region and households in the poorer expenditure quartiles. Multivariable logistic regression revealed that households were more likely to face CHE if they; consisted of chronically ill member(s), have a higher burden of acute illness and injuries, have elderly (>=60 years) member(s), belonged to the poor expenditure quartile, and were located in the far-western region. In contrast, households were less likely to incur CHE when their household head was educated. Having children (<=5 years) in households did not significantly affect catastrophic health expenditure. CONCLUSIONS: This study identified a high cumulative incidence of CHE. CHE was disproportionately concentrated in the poor households and households located in the far-western region. Policy-makers should focus on prioritizing households vulnerable to CHE. Interventions to reduce economic burden of out-of-pocket healthcare payment are imperative to lower incidences of CHE among those households. Improving literacy rate might also be useful in order to lower CHE and facilitate universal health coverage. PMID- 29444687 TI - Psychometric properties of the medical outcomes study: social support survey among methadone maintenance patients in Ho Chi Minh City, Vietnam: a validation study. AB - BACKGROUND: Social support plays a crucial role in the treatment and recovery process of patients engaging in methadone maintenance treatment (MMT). However, there is a paucity of research about social support among MMT patients, possibly due to a lack of appropriate measuring tools. This study aimed to evaluate the psychometric properties of the Vietnamese version of the Medical Outcomes Study: Social Support Survey (MOS-SSS) among MMT patients. METHODS: A cross-sectional survey of 300 patients was conducted in a methadone clinic in Ho Chi Minh City, Vietnam. MMT patients who agreed to participate in the study completed a face-to face interview in a private room. The MOS-SSS was translated into Vietnamese using standard forward-backward process. Internal consistency was measured by Cronbach's alpha. The intra-class correlation coefficient was used to determine the test-retest reliability of the MOS-SSS in 75 participants two weeks after the first survey. Concurrent validity of the MOS-SSS was evaluated by correlations with the Multidimensional Scale of Perceived Social Support (MSPSS) and the Perceived Stigma of Addiction Scale (PSAS). Construct validity was investigated by confirmatory factor analysis. RESULTS: The MOS-SSS had good internal consistency with Cronbach's alpha from 0.95 to 0.97 for the four subscales and 0.97 for the overall scale. The two-week test-retest reliability was at moderate level with intra-class correlation coefficients of 0.61-0.73 for the four subscales and 0.76 for the overall scale. Strong significant correlations between the MOS-SSS and the MSPSS (r = 0.77; p < 0.001) and the PSAS (r = - 0.76; p < 0.001) indicated good concurrent validity. Construct validity of the MOS-SSS was established since a final four-factor model fitted the data well with Comparative Fit Index (0.97), Tucker-Lewis Index (0.97), Standardized Root Mean Square Residual (0.03) and Root Mean Square Error of Approximation (0.068; 90% CI = 0.059-0.077). CONCLUSIONS: The MOS-SSS is a reliable and valid tool for measuring social support in Vietnamese MMT patients. Further studies among methadone patients at different stages of their treatment and among those from different areas of Vietnam are needed. PMID- 29444689 TI - Comprehensive knowledge on cervical cancer, attitude towards its screening and associated factors among women aged 30-49 years in Finote Selam town, northwest Ethiopia. AB - BACKGROUND: Screening services for cervical pre-cancerous lesions is currently available for all women aged 30-49 years at public hospitals in Ethiopia. Though women's knowledge and their attitude are determinants for the uptake the screening service, there is limited information on these regards. Therefore, this study aimed to assess comprehensive knowledge on cervical cancer, attitudes towards the screening, and associated factors among women aged 30-49 years at Finote Selam town, northwest Ethiopia. METHODS: A community based cross-sectional study was conducted from March 30, to April 15, 2017. The sample size calculated for this study was 1224 and a cluster sampling technique was used to select the participants from three randomly selected kebeles. Epi-Info version 7 and Statistical Package for Social Sciences version 20 were used for data entry and analysis respectively. A binary logistic regression model was used. In multivariable logistic analysis, adjusted odds ratio with a 95% confidence interval was used to determine the presence and strength of associations between covariate and outcome variable. RESULTS: A total of 1137 women participated in this study. Nearly one third, 30.3% (95%CI: 27.7, 32.9) of the women had knowledge of cervical cancer, and 58.1% (95% CI: 55, 62.2) had a favorable attitude towards cervical cancer screening. In the multivariable analysis, having college and above education (AOR = 7.21, 95%CI: 3.41, 15.29), knowing someone with cervical cancer (AOR =5.38, 95%CI: 2.38, 12.15), and having a history of sexually transmitted diseases (AOR = 2.75, 95%CI: 1.24, 6.04) were significantly associated with knowledge on cervical cancer. Meanwhile, college and above educational status (AOR = 2.56, 95%CI: 1.14, 5.69), knowing someone with cervical cancer (AOR = 3.24, 95%CI: 1.14, 9.15), and having knowledge of cervical cancer (AOR = 3, 95%CI: 1.97, 4.29) were positively associated with favorable attitudes towards cervical cancer screening. CONCLUSION: The proportion of women who had knowledge on cervical cancer was low where as relatively, a large proportion of the study participants in this study had favorable attitude towards cervical cancer screening. Educational status, knowing someone with cervical cancer, a history of sexually transmitted diseases was factors affecting both women's knowledge and their attitude. Having knowledge on cervical cancer was factor affecting attitude towards screening services. Provision of information, education, and counseling about the disease and screening service are mandatory to address their knowledge gap and to improve women's attitude towards screening service. PMID- 29444688 TI - Twenty years of home-based palliative care in Malappuram, Kerala, India: a descriptive study of patients and their care-givers. AB - BACKGROUND: The well lauded community-based palliative care programme of Kerala, India provides medical and social support, through home-based care, for patients with terminal illness and diseases requiring long-term support. There is, however, limited information on patient characteristics, caregivers and programme performance. This study was carried out to describe: i) the patients enrolled in the programme from 1996 to 2016 and their diagnosis, and ii) the care-giver characteristics and palliative care support from nurses and doctors in a cohort of patients registered during 2013-2015. METHODS: A descriptive study was conducted in the oldest community-based palliative clinic in Kerala. Data were collected from annual patient registers from 1996 to 2016 and patient case records during the period 2013-2015. RESULTS: While 91% of the patients registered in the clinic in 1996 had cancer, its relative proportion came down to 32% in 2016 with the inclusion of dementia-related illness (19%) cardiovascular accidents (17%) and severe mental illness (5%).Among patients registered during 2013-15, the median number of home visits from nurses and doctors in 12 months were five and one respectively. In the same cohort, twelve months' post enrolment, 56% of patients died, 30% were in continuing in active care and 7% opted out. Those who opted out of care were likely to be aged < 60 years, received one or less visit annually from a doctor or have a serious mental illness. 96% of patients had a care-giver at home, 85% of these care-givers being female. CONCLUSIONS: The changing dynamics over a 20-year period of this palliative care programme in Kerala, India, highlights the need for similar programmes to remain flexible and adapt their services in response to a growing global burden of Non Communicable Diseases. While a high death rate is expected in this population, the high proportion of patients choosing to stay in the programme suggests that home-based care is valued within this particular group. A diverse range of clinical and psycho-social support skills are required to assist families and their caregivers when caring for a cohort such as this one. PMID- 29444690 TI - Efficacy of N,N'bis-(2-mercaptoethyl) isophthalamide on mercury intoxication: a randomized controlled trial. AB - BACKGROUND: Chronic mercury intoxication is a severe health issue and occurs especially in gold mining communities. Common chelators used for improving mercury elimination are not everywhere available and challenged by poor cell wall penetration. This study is part of a feasibility trial and the aim was to gather first information about the efficacy of the newly developed chelator N,N'bis-(2 mercaptoethyl) isophthalamide (NBMI) on chronic mercury intoxication. METHODS: In this three-armed, placebo-controlled randomized trial, 36 miners with mercury urine levels exceeding 15 MUg/l were administered 100 mg NBMI, 300 mg NBMI or placebo for 14 days. Levels of mercury in urine [MUg/l and MUg/g creatinine] and plasma l were analyzed. Therapeutic effect was assessed using the medical intoxication score (MIS) and its single health outcomes (e.g. excessive salivation, sleeping problems), fatigue scores, a neuromotoric test battery (CATSYS) and a neurological outcome (Finger to nose test). RESULTS: Physical fatigue was significantly decreased in the 300 mg NBMI group compared to the control. Mercury concentration in urine following 300 mg NBMI treatment was significantly lowered compared to control, however, this effect was less distinct with adjustment for creatinine. CONCLUSION: NBMI showed an effect on physical fatigue and there were indications to positive effects on other symptoms as well. More comprehensive studies are mandatory to verify the effects of NBMI as a novel tool for treating mercury intoxications. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02486289 . Date of registration: June 24, 2015. PMID- 29444691 TI - Affinity proteomic profiling of plasma for proteins associated to area-based mammographic breast density. AB - BACKGROUND: Mammographic breast density is one of the strongest risk factors for breast cancer, but molecular understanding of how breast density relates to cancer risk is less complete. Studies of proteins in blood plasma, possibly associated with mammographic density, are well-suited as these allow large-scale analyses and might shed light on the association between breast cancer and breast density. METHODS: Plasma samples from 1329 women in the Swedish KARMA project, without prior history of breast cancer, were profiled with antibody suspension bead array (SBA) assays. Two sample sets comprising 729 and 600 women were screened by two different SBAs targeting a total number of 357 proteins. Protein targets were selected through searching the literature, for either being related to breast cancer or for being linked to the extracellular matrix. Association between proteins and absolute area-based breast density (AD) was assessed by quantile regression, adjusting for age and body mass index (BMI). RESULTS: Plasma profiling revealed linear association between 20 proteins and AD, concordant in the two sets of samples (p < 0.05). Plasma levels of seven proteins were positively associated and 13 proteins negatively associated with AD. For eleven of these proteins evidence for gene expression in breast tissue existed. Among these, ABCC11, TNFRSF10D, F11R and ERRF were positively associated with AD, and SHC1, CFLAR, ACOX2, ITGB6, RASSF1, FANCD2 and IRX5 were negatively associated with AD. CONCLUSIONS: Screening proteins in plasma indicates associations between breast density and processes of tissue homeostasis, DNA repair, cancer development and/or progression in breast cancer. Further validation and follow-up studies of the shortlisted protein candidates in independent cohorts will be needed to infer their role in breast density and its progression in premenopausal and postmenopausal women. PMID- 29444692 TI - Western and Modern Mexican dietary patterns are directly associated with incident hypertension in Mexican women: a prospective follow-up study. AB - BACKGROUND: Research has found that diet and dietary patterns are associated with blood pressure and hypertension. Limited research in this area has been conducted in a Mexican population. METHODS: We investigated the relation between dietary patterns (principal component analysis) and the incidence of self-reported treated hypertension in 62,913 women from the Mexican Teachers' Cohort, a large population-based cohort of female Mexican teachers, who were free of hypertension at baseline in 2006-2008 when diet was assessed using a food frequency questionnaire. Dietary patterns were categorized into quartiles and logistic regression models were fit. RESULTS: Participants were 42.1 +/- 7.3 years old, had a BMI 27.0 +/- 4.4 and a cumulative incidence of hypertension of 4.6%. Between baseline and first follow-up (2011-2014) we identified 2916 incident cases of hypertension. We identified three major components. The first was loaded heavily with vegetables, fruits and legumes; the second component was loaded heavily with processed meats, fast foods, and red meat; and finally the third component was loaded heavily with corn tortillas, hot peppers, and sodas. We named the components as Fruits & Vegetables (FV), Western (W), and Modern Mexican (MM). The multivariable-adjusted odds of hypertension in the highest quartile of the W pattern were 24% higher than the odds for individuals in the lowest quartile (95%CI = 1.10, 1.40; P-trend = 0.0004); women in the highest quartile of the MM pattern had 15% higher odds than women in the lowest quartile (95%CI = 1.02, 1.29; P-trend = 0.01). The FV pattern was not significantly associated with hypertension (OR for extreme quartiles = 0.94; 95%CI = 0.84, 1.05; P-trend = 0.19). CONCLUSION: The Western pattern and the Modern Mexican pattern, which showcases an undergoing nutrition transition, may affect the incidence of hypertension, whereas the FV pattern was not associated with hypertension. These findings are important in the prevention of hypertension and cardiovascular diseases in Mexico and possibly among Mexican people living in the US.

AB - BACKGROUND: Volumetric-modulated Dynamic WaveArc therapy (VMDWAT) is a non coplanar continuous volumetric modulated radiation therapy (VMAT) delivery technique. Here, we monitored mechanical errors and their impact on dose distributions in VMDWAT using logfiles throughout the course of treatment. METHODS: Fifteen patients were enrolled (2 skull base tumor patients and 13 prostate cancer patients). VMDWAT plans were created for the enrolled patients. The prescribed dose for the skull base tumor was set as 54 Gy at 1.8 Gy per fraction, and that for the prostate cancer was set as 72 to 78 Gy at 2 Gy per fraction. We acquired logfiles to monitor mechanical errors and their impact on dose distribution in each fraction. The root mean square error (RMSE) in the multi-leaf collimator (MLC), gantry angle, O-ring angle and monitor unit (MU) were calculated using logfiles throughout the course of VMDWAT for each patient. The dosimetric impact of mechanical errors throughout the course of VMDWAT was verified using a logfile-based dose reconstruction method. Dosimetric errors between the reconstructed plans and the original plans were assessed. RESULTS: A total of 517 datasets, including 55 datasets for the 2 skull base tumor patients and 462 datasets for the 13 prostate cancer patients, were acquired. The RMSE values were less than 0.1 mm, 0.2 degrees , 0.1 degrees , and 0.4 MU for MLC position, gantry angle, O-ring angle, and MU, respectively. For the skull base tumors, the absolute mean dosimetric errors and two standard deviations throughout the course of treatment were less than 1.4% and 1.1%, respectively. For prostate cancer, these absolute values were less than 0.3% and 0.5%, respectively. The largest dosimetric error of 2.5% was observed in a skull base tumor patient. The resultant dosimetric error in the accumulated daily delivered dose distribution, in the patient with the largest error, was up to 1.6% for all dose-volumetric parameters relative to the planned dose distribution. CONCLUSIONS: MLC position, gantry rotation, O-ring rotation and MU were highly accurate and stable throughout the course of treatment. The daily dosimetric errors due to mechanical errors were small. VMDWAT provided high delivery accuracy and stability throughout the course of treatment. TRIAL REGISTRATION: UMIN000023870 . Registered: 1 October 2016. PMID- 29444694 TI - Reliability and construct validity of the Ottawa valve collapse scale when assessing external nasal valve collapse. AB - BACKGROUND: Nasal valve collapse is a common cause of nasal obstruction in otolaryngology practice. Common examination methods, such as the Cottle Maneuver and modified Cottle Maneuver are available. However, these methods are dichotomous and do not provide ordinal severity information. The Ottawa Valve Collapse Scale (OVCS) is a grading system for assessing and easily grading external nasal valve collapse in patients with a septal deviation. The primary objective was to assess the test-retest reliability and construct validity of the OVCS grading scale. A secondary objective was to perform the same assessments on the Cottle Maneuver. METHODS: Patients with a septal deviation who were requesting surgical correction were prospectively enrolled in the study. All patients were assessed using both the Cottle Maneuver and the OVCS by one otolaryngologist at two visits separated by one month. The phi coefficient was calculated to assess the test-retest reliability of the instruments. Results of the Nasal Obstruction Symptom Evaluation (NOSE) Score was compared to determine construct validity. RESULTS: Ninety-two patients met our inclusion criteria. The phi coefficient was 0.62 for the OVCS and 0.32 for the Cottle Maneuver. The scores on the NOSE instrument were positively associated with the OVCS scores (p = 0.01) while there was no association with the Cottle Maneuver (p = 047). CONCLUSION: This current preliminary analysis suggests that the novel Ottawa Valve Collapse Scale has good test-retest reliability and construct validity. This scale may help clinicians grade external nasal valve collapse in patients with a septal deviation. Future studies are required to determine if this scale assists surgeons in determining which patients need formal nasal valve surgery in addition to a standard septoplasty. PMID- 29444695 TI - The impact of manual rotation of the occiput posterior position on spontaneous vaginal delivery rate: study protocol for a randomized clinical trial (RMOS). AB - BACKGROUND: The frequency of posterior presentations (occiput of the fetus towards the sacrum of the mother) in labor is approximately 20% and, of this, 5% remain posterior until the end of labor. These posterior presentations are associated with higher rates of cesarean section and instrumental delivery. Manual rotation of a posterior position in order to rotate the fetus to an anterior position has been proposed in order to reduce the rate of instrumental fetal delivery. No randomized study has compared the efficacy of this procedure to expectant management. We therefore propose a monocentric, interventional, randomized, prospective study to show the superiority of vaginal delivery rates using the manual rotation of the posterior position at full dilation over expectant management. METHODS: Ultrasound imaging of the presentation will be performed at full dilation on all the singleton pregnancies for which a clinical suspicion of a posterior position was raised at more than 37 weeks' gestation (WG). In the event of an ultrasound confirming a posterior position, the patient will be randomized into an experimental group (manual rotation) or a control group (expectative management with no rotation). For a power of 90% and the hypothesis that vaginal deliveries will increase by 20%, (10% of patients lost to follow-up) 238 patients will need to be included in the study. The primary endpoint will be the rate of spontaneous vaginal deliveries (expected rate without rotation: 60%). The secondary endpoints will be the rate of fetal extractions (cesarean or instrumental) and the maternal and fetal morbidity and mortality rates. The intent-to-treat study will be conducted over 24 months. Recruitment started in February 2017. To achieve the primary objective, we will perform a test comparing the number of spontaneous vaginal deliveries in the two groups using Pearson's chi-squared test (provided that the conditions for using this test are satisfactory in terms of numbers). In the event that this test cannot be performed, we will use Fisher's exact test. DISCUSSION: Given that the efficacy of manual rotation has not been proven with a high level of evidence, the practice of this technique is not systematically recommended by scholarly societies and is, therefore, rarely performed by obstetric gynecologists. If our hypothesis regarding the superiority of manual rotation is confirmed, our study will help change delivery practices in cases of posterior fetal position. An increase in the rates of vaginal delivery will help decrease the short- and long term rates of morbidity and mortality following cesarean section. Manual rotation is a simple and effective method with a success rate of almost 90%. Several preliminary studies have shown that manual rotation is associated with reduced rates for fetal extraction and maternal complications: Shaffer has shown that the cesarean section rate is lower in patients for whom a manual rotation is performed successfully (2%) with a 9% rate of cesarean sections when manual rotation is performed versus 41% when it is not performed. Le Ray has shown that manual rotation significantly reduces vaginal delivery rates via fetal extraction (23.2% vs 38.7%, p < 0.01). However, manual rotation is not systematically performed due to the absence of proof of its efficacy in retrospective studies and quasi-experimental before/after studies.

PMID- 29444696 TI - Bedside analysis of the sublingual microvascular glycocalyx in the emergency room and intensive care unit - the GlycoNurse study. AB - BACKGROUND: Deterioration of the endothelial glycocalyx (eGC), a protective carbohydrate-rich layer lining the luminal surface of the endothelium, plays a key role in vascular barrier dysfunction and eventually organ-failure in systemic inflammatory response syndrome and sepsis. Early detection of glycocalyx damage could thus become an important goal in critical care. This study was designed to determine the feasibility and reproducibility of quantitative, real-time glycocalyx measurements performed at bedside in the emergency room (ER) and intensive care unit (ICU). METHODS: The observational study included 70 patients admitted to the ER or ICU of a university hospital. A physician and the nurse in charge of the patient performed sublingual microcirculatory measurements using sidestream dark field (SDF) imaging. A novel data acquisition and analysis software (GlycoCheckTM) was used to analyze the perfused boundary region (PBR), an inverse parameter of endothelial glycocalyx dimensions in vessels with diameters of between 5 and 25 MUm. RESULTS: The method showed a good intra observer reproducibility. Specifically, intraclass correlation coefficient analysis showed an excellent reproducibility between the physician's measurements (0.77 [CI 95%: 0.52-0.89]). The bias between the two PBRs was - 0.077 +/- 0.24 MUm. Moreover, there were no significant differences in the PBR values obtained by the nurses when compared to those reported by the physician (regarded as the "gold standard" measurement). Intraclass correlation coefficient analysis showed excellent reproducibility between the nurses' and physician's PBRs (0.75 [95% CI: 0.52-0.87]). The mean difference between the two PBRs (i.e., the bias) was 0.007 +/- 0.25 MUm. The nurses' PBR assessment had a 90% sensitivity (95% CI: 60-99%) and 90% specificity (95% CI: 80-93%) to identify a severely impaired glycocalyx. CONCLUSION: Glycocalyx dimensions can be measured at patients' bedside precisely by non-invasive assessment of the PBR. This assessment could become part of standard monitoring and contribute to clinical decision-making and resuscitation protocols in clinical trials and daily practice.

AB - OBJECTIVE: We aimed to evaluate the potential of DODAC/PHO-S liposomes on the modulation of the expression of pro-apoptotic proteins, loss of lysosomal integrity and the mitochondrial electrical potential, compared with phosphoethanolamine. RESULTS: The results of this study demonstrate that DODAC/PHO-S liposomes have exhibited broad cytotoxic potential in B16F10 murine melanoma cells, with significantly greater proportions than treatment with PHO-S. The treatment with the DODAC/PHO-S 2.0 mM liposomal formulation was more efficient in decreasing mitochondrial electrical potential at the same concentrations and treatment time than PHO-S The liposomal formulation DODAC/PHO S (2.0 mM) was more efficient to promote morphological changes in the cells, without presenting intact lysosomes, at the same time of treatment and concentration as PHO-S Our results demonstrated that the liposomal formulation increased DR4 receptor expression and activated caspases 8 and 3, resulting in the release of cytochrome c in B16F10 tumour cells, when compared to treatment with PHO-S The data obtained prove that the use of DODAC as carrier can maximize the cytotoxic effects of PHO-S This was demonstrated by the translocation of cytochrome c to the cytoplasm and activation of caspase-3 and 8, decreasing the mitochondrial electrical potential and generating morphological changes, in B16F10 cells. PMID- 29444698 TI - Using OWL reasoning to support the generation of novel gene sets for enrichment analysis. AB - BACKGROUND: The Gene Ontology (GO) consists of over 40,000 terms for biological processes, cell components and gene product activities linked into a graph structure by over 90,000 relationships. It has been used to annotate the functions and cellular locations of several million gene products. The graph structure is used by a variety of tools to group annotated genes into sets whose products share function or location. These gene sets are widely used to interpret the results of genomics experiments by assessing which sets are significantly over- or under-represented in results lists. F Hoffmann-La Roche Ltd. has developed a bespoke, manually maintained controlled vocabulary (RCV) for use in over-representation analysis. Many terms in this vocabulary group GO terms in novel ways that cannot easily be derived using the graph structure of the GO. For example, some RCV terms group GO terms by the cell, chemical or tissue type they refer to. Recent improvements in the content and formal structure of the GO make it possible to use logical queries in Web Ontology Language (OWL) to automatically map these cross-cutting classifications to sets of GO terms. We used this approach to automate mapping between RCV and GO, largely replacing the increasingly unsustainable manual mapping process. We then tested the utility of the resulting groupings for over-representation analysis. RESULTS: We successfully mapped 85% of RCV terms to logical OWL definitions and showed that these could be used to recapitulate and extend manual mappings between RCV terms and the sets of GO terms subsumed by them. We also show that gene sets derived from the resulting GO terms sets can be used to detect the signatures of cell and tissue types in whole genome expression data. CONCLUSIONS: The rich formal structure of the GO makes it possible to use reasoning to dynamically generate novel, biologically relevant groupings of GO terms. GO term groupings generated with this approach can be used in. over-representation analysis to detect cell and tissue type signatures in whole genome expression data. PMID- 29444699 TI - The HYSTER study: the effect of intracervically administered terlipressin versus placebo on the number of gaseous emboli and fluid intravasation during hysteroscopic surgery: study protocol for a randomized controlled clinical trial. AB - BACKGROUND: Transcervical resection of myoma or endometrium is a safe, hysteroscopic, minimally invasive procedure. However, intravasation of distension fluid is a common phenomenon during these procedures. In a previous study we observed venous gas emboli in almost every patient. The severity of hysteroscopic derived embolization has been shown to be correlated to the amount of intravasation. In addition, paradoxical gas embolism, which is potentially dangerous, was observed in several patients. Studies have shown a reduction of intravasation by using intracervically administered vasopressin during hysteroscopy. We think that its analog, terlipressin, should have the same effect. In our previous research we observed more gaseous emboli as intravasation increased. Whether or not the insertion of intracervically administered terlipressin leads to a lower incidence and severity of gas embolism is unknown. We hypothesize that intracervically administered terlipressin leads to a reduction of intravasation with a lower incidence and severity of gas embolism. Terlipressin may be of benefit during hysteroscopic surgery. METHODS/DESIGN: Forty-eight patients (ASA 1 or 2) scheduled for transcervical resection of large, types 1-2 myoma or extensive endometrium resection will be included. In a double blind fashion patients will be randomized 1:1 according to surgical treatment using either intracervically administered terlipressin or placebo. Transesophageal echocardiography will be used to observe and record embolic events. A pre- and post-procedure venous blood sample will be taken to calculate intravasation based on hemodilution. Our primary endpoint will be how terlipressin influences the severity of embolic events. Secondary endpoints include the effect of terlipressin on the amount of intravasation and on hemodynamic parameters. DISCUSSION: If terlipressin does indeed reduce the number of gaseous emboli and intravasation occurring during hysteroscopic surgery, it would be a simple method to minimize potential adverse events. It also allows for prolonged operating time before the threshold of intravasation is reached, thereby reducing the need for a second operation.

PMID- 29444700 TI - Pharmacotherapies for fatigue in chronic liver disease (CLD): a systematic review and meta-analysis (protocol). AB - BACKGROUND: This is the protocol for a systematic review (and meta-analysis) of an intervention. The primary objective of this systematic review will be to assess the benefits and harms of pharmacological therapies (pharmacotherapies) for the management of fatigue in adults with CLD of any etiology. The effects of pharmacological therapies on fatigue in CLD will be compared against those of placebo, no intervention, or non-pharmacological interventions. Specifically, this review will examine whether pharmacological therapies improve CLD-associated fatigue, and if they do, what key elements are associated with their effectiveness. The results of this systematic review will assist clinicians, policy-makers, researchers, and people with CLD in decision-making on how best to manage fatigue and its associated symptoms. METHODS: MEDLINE, SCOPUS, EMBASE, EU Clinical Trials Register, WHO International Clinical Trials Registry Platform, CENTRAL (The Cochrane Library), ClinicalTrials.gov, reference lists of articles and conference proceedings will be searched for relevant studies. No language or date restrictions will be applied. Eligible studies will include adults with CLD of any etiology. Included studies will be randomized controlled trials. From included studies, data on participant characteristics, study design, setting, research ethics compliance, and intervention outcomes will be extracted. Risk of bias in included studies will be assessed using the Cochrane Risk of Bias Tool. A random-effects meta-analysis will be conducted. If substantial or considerable levels of heterogeneity are detected, analysis will be limited to a narrative synthesis. DISCUSSION: This systematic review will examine the effectiveness of pharmacological therapies on fatigue reduction in people with CLD. Such therapies may be more effective than non-pharmacological interventions in treating fatigue symptoms in CLD. Evidence derived from the findings of this study will guide future practice, policy, and research. SYSTEMATIC REVIEW REGISTRATION: PROSPERO, CRD42017076957. PMID- 29444701 TI - A case series on common cold to severe bronchiolitis and pneumonia in children following human metapneumovirus infection in Sri Lanka. AB - OBJECTIVES: The prevalence of hMPV infections in Sri Lanka has not been reported and here we report a case series of hMPV infection in children less than 5 years. Patients with ARTI were included from Teaching Hospital, Anuradhapura from March 2013 to August 2014. Indirect fluorescence assay was performed on nasopharyngeal aspirates for the identification of respiratory viruses [respiratory syncytial virus (RSV), parainfluenza virus 1, 2 and 3, influenza A and B and hMPV]. Moreover, reverse transcriptase-polymerase chain reaction was done to further confirm the hMPV infection. RESULTS: In this case series, hMPV infection showed a range of respiratory symptoms from common cold to life threatening lower respiratory tract infections with varying severity. In some cases, the clinical presentation of hMPV infection was similar to the ARTI caused by RSV. hMPV co infections with of RSV have also been seen in some cases of ARTI. A child delivered through cesarean section and birth order > 3 has an Odds ratio of 3.5 and 4.3 (95% CI) for developing co-infection with RSV compared to hMPV mono infections. Lack of diagnostic facilities to identify the viral aetiology has contributed to the use of antibiotics indicating the need for establishing viral diagnostic facilities in the country.

PMID- 29444703 TI - Whole bone testing in small animals: systematic characterization of the mechanical properties of different rodent bones available for rat fracture models. AB - OBJECTIVES: Rat fracture models are extensively used to characterize normal and pathological bone healing. Despite, systematic research on inter- and intra individual differences of common rat bones examined is surprisingly not available. Thus, we studied the biomechanical behaviour and radiological characteristics of the humerus, the tibia and the femur of the male Wistar rat all of which are potentially available in the experimental situation-to identify useful or detrimental biomechanical properties of each bone and to facilitate sample size calculations. METHODS: 40 paired femura, tibiae and humeri of male Wistar rats (10-38 weeks, weight between 240 and 720 g) were analysed by DXA, pQCT scan and three-point-bending. Bearing and loading bars of the biomechanical setup were adapted percentually to the bone's length. Subgroups of light (skeletal immature) rats under 400 g (N = 11, 22 specimens of each bone) and heavy (mature) rats over 400 g (N = 9, 18 specimens of each bone) were formed and evaluated separately. RESULTS: Radiologically, neither significant differences between left and right bones, nor a specific side preference was evident. Mean side differences of the BMC were relatively small (1-3% measured by DXA and 2.5 5% by pQCT). Over all, bone mineral content (BMC) assessed by DXA and pQCT (TOT CNT, CORT CNT) showed high correlations between each other (BMC vs. TOT and CORT CNT: R2 = 0.94-0.99). The load-displacement diagram showed a typical, reproducible curve for each type of bone. Tibiae were the longest bones (mean 41.8 +/- 4.12 mm) followed by femurs (mean 38.9 +/- 4.12 mm) and humeri (mean 29.88 +/- 3.33 mm). Failure loads and stiffness ranged from 175.4 +/- 45.23 N / 315.6 +/- 63.00 N/mm for the femurs, 124.6 +/- 41.13 N / 260.5 +/- 59.97 N/mm for the humeri to 117.1 +/- 33.94 N / 143.8 +/- 36.99 N/mm for the tibiae. Smallest interindividual differences were observed in failure loads of the femurs (CV% 8.6) and tibiae (CV% 10.7) of heavy animals, light animals showed good consistency in failure loads of the humeri (CV% 7.7). Most consistent results of both sides (left vs. right) in failure loads were provided by the femurs of light animals (mean difference 4.0 +/- 2.8%); concerning stiffness, humeri of heavy animals were most consistent (mean difference of 6.2 +/- 5%). In general, the failure loads showed strong correlations to the BMC (R2 = 0.85-0.88) whereas stiffness correlated only moderate, except for the humerus (BMC vs. stiffness: R2 = 0.79). DISCUSSION: Altogether, the rat's femur of mature specimens showed the most accurate and consistent radiological and biomechanical results. In synopsis with the common experimental use enabling comparison among different studies, this bone offers ideal biomechanical conditions for three point bending experiments. This can be explained by the combination of a superior aspect ratio and a round and long, straight morphology, which satisfies the beam criteria more than other bones tested. PMID- 29444704 TI - hPMSC transplantation restoring ovarian function in premature ovarian failure mice is associated with change of Th17/Tc17 and Th17/Treg cell ratios through the PI3K/Akt signal pathway. AB - BACKGROUND: Human placenta-derived mesenchymal stem cell (hPMSC) transplantation has been demonstrated to be an effective way of recovering ovarian function in mice with autoimmune induced premature ovarian failure (POF). But the exact mechanism remains unclear. The goal of the present study is to investigate the role of immune factors (T-helper 17 (Th17), cytotoxic T (Tc17) and regulatory T (Treg) cells) in the recovery of ovarian function and whether the phosphatidylinositol 3-kinase (PI3K)/Akt signal pathway is involved in the regulation. METHODS: The inhibitor of PI3K/Akt was administered to observe its effect on ovarian function recovery and immune regulation. Serum levels of estradiol (E2), follicle stimulation hormone (FSH), luteinizing hormone (LH) and anti-Mullerian hormone (AMH)) and anti-Zona pellucida antibody (AZPAb) were measured by ELISA to evaluate ovarian function. The morphological changes of ovaries were observed by HE staining. Apoptosis of granular cells (GCs) was determined by detecting the expression of capase-3. Expression of p-Akt protein was detected by immunohistochemistry and western blot assay in ovarian tissues. The MTT assay was performed to assess GC proliferation. GC apoptosis was performed using flow cytometry analysis. Percentages of Th17, Tc17 and Treg cells were detected by flow cytometry. Expression of interleukin (IL)-17 in serum was measured by ELISA. RESULTS: LY294002 administration decreased serum levels of E2 and AMH, while the levels of FSH, LH and AZPAb in serum were increased compared with mice in the hPMSC transplantation group. The ovarian morphology presented as atrophy and fibrosis, with functional follicles exhausted. The expression of p Akt in ovarian tissue was significantly decreased. Also, LY294002 administration significantly decreased proliferation and increased cell apoptosis in GCs, and for immune factors the ratios of Th17/Tc17 and Th17/Treg cells were significantly increased, as well as the serum levels of IL-17. CONCLUSIONS: Our data suggest that the PI3K/Akt signal pathway is involved in the recovery of ovarian function by changing the ratios of Th17/ Tc17 and Th17/Treg cells in POF mice following hPMSC transplantation. PMID- 29444705 TI - Health economic evaluation of moist wound care in chronic cutaneous leishmaniasis ulcers in Afghanistan. AB - BACKGROUND: The present health economic evaluation in Afghanistan aims to support public health decision makers and health care managers to allocate resources efficiently to appropriate treatments for cutaneous leishmaniasis (CL) elicited by Leishmania tropica or Leishmania major. METHODS: A decision tree was used to analyse the cost and the effectiveness of two wound care regimens versus intra lesional antimony in CL patients in Afghanistan. Costs were collected from a societal perspective. Effectiveness was measured in wound free days. The incremental cost-effectiveness ratio (ICER) and incremental net monetary benefit (NMB) were calculated. The model was parameterized with baseline parameters, sensitivity ranges, and parameter distributions. Finally, the model was simulated and results were evaluated with deterministic and probability sensitivity analyses. Final outcomes were the efficiency of the regimens and a budget impact analysis in the context of Afghanistan. RESULTS: Average costs per patients were US$ 11 (SE = 0.016) (Group I: Intra-dermal Sodium Stibogluconate [IL SSG]), US$ 16 (SE = 7.58) (Group II: Electro-thermo-debridement [ETD] + Moist wound treatment [MWT]) and US$ 25 (SE = 0.48) (Group III: MWT) in patients with a single chronic CL ulcer. From a societal perspective the budget impact analysis shows that the regimens' drug costs are lower than indirect disease cost. Average effectiveness in wound free days are 177 (SE = 0.36) in Group II, 147 (SE = 0.33) in Group III, and 129 (SE = 0.27) in Group I. The ICER of Group II versus Group I was US$ 0.09 and Group III versus Group I US$ 0.77, which is very cost-effective with a willingness-to-pay threshold of US$ 2 per wound free day. Within a Monte Carlo probabilistic sensitivity analysis Group II was cost-effective in 80% of the cases starting at a willingness-to-pay of 80 cent per wound free day. CONCLUSIONS: Group II provided the most cost-effective treatment. The non treatment alternative is not an option in the management of chronic CL ulcers. MWT of Group III should at least be practiced. The cost-effectiveness of Group III depends on the number of dressings necessary until complete wound closure. PMID- 29444706 TI - Bilateral Piriform sinus fistulas: a case study and review of management options. AB - BACKGROUND: Piriform sinus fistulas occur due to developmental abnormalities of the third and fourth branchial arches, and almost always occur unilaterally. They generally present as recurrent abscesses in the anterior-inferior neck, with concurrent thyroiditis. They have conventionally been managed with complete removal of the sinus tract, and thyroidectomy if required; however, endoscopic approaches have been increasingly favored. Herein we describe a case of bilateral piriform sinus fistulas, and present a review of the literature concerning their endoscopic management. CASE PRESENTATION: Our patient was determined to have bilateral piriform sinus fistulas based on computer tomography, magnetic resonance imaging and microlaryngoscopy. We performed electrocauterization of the proximal fistula tracts, followed by injection of fibrin sealent. Our patient has not had a recurrence in the ten months since his procedure. There were no complications. Twenty-three articles describing an endoscopic approach to these fistulas were identified through PubMed, and a search through the references of related articles was completed. CONCLUSION: Of one hundred and ninety-five patient cases we reviewed, an endoscopic procedure success rate of 82% and complication rate of 5.6% was determined. Piriform sinus fistulas that occur bilaterally are a rare congenital abnormality of the neck. Endoscopic approaches are an acceptable alternative option to open procedures, with similar success and a lower rate of complications. PMID- 29444708 TI - Rasch analysis of the Trypophobia Questionnaire. AB - OBJECTIVE: This study aimed to assess Rasch-based psychometric properties of the Trypophobia Questionnaire measuring proneness to trypophobia, which refers to disgust and unpleasantness induced by the observation of clusters of objects (e.g., lotus seed pods). RESULTS: Rasch analysis was performed on data from 582 healthy Japanese adults. The results suggested that Trypophobia Questionnaire has a unidimensional structure with ordered response categories and sufficient person and item reliabilities, and that it does not have differential item functioning across sexes and age groups, whereas the targeting of the scale leaves room for improvements. When items that did not fit the Rasch model were removed, the shortened version showed slightly improved psychometric properties. However, results were not conclusive in determining whether the full or shortened version is better for practical use. Further assessment and validation are needed. PMID- 29444707 TI - Percutaneous transhepatic vs. endoscopic retrograde biliary drainage for suspected malignant hilar obstruction: study protocol for a randomized controlled trial. AB - BACKGROUND: The optimal approach to the drainage of malignant obstruction at the liver hilum remains uncertain. We aim to compare percutaneous transhepatic biliary drainage (PTBD) to endoscopic retrograde cholangiography (ERC) as the first intervention in patients with cholestasis due to suspected malignant hilar obstruction (MHO). METHODS: The INTERCPT trial is a multi-center, comparative effectiveness, randomized, superiority trial of PTBD vs. ERC for decompression of suspected MHO. One hundred and eighty-four eligible patients across medical centers in the United States, who provide informed consent, will be randomly assigned in 1:1 fashion via a web-based electronic randomization system to either ERC or PTBD as the initial drainage and, if indicated, diagnostic procedure. All subsequent clinical interventions, including crossover to the alternative procedure, will be dictated by treating physicians per usual clinical care. Enrolled subjects will be assessed for successful biliary drainage (primary outcome measure), adequate tissue diagnosis, adverse events, the need for additional procedures, hospitalizations, and oncological outcomes over a 6-month follow-up period. Subjects, treating clinicians and outcome assessors will not be blinded. DISCUSSION: The INTERCPT trial is designed to determine whether PTBD or ERC is the better initial approach when managing a patient with suspected MHO, a common clinical dilemma that has never been investigated in a randomized trial.

PMID- 29444709 TI - Mucinous cystic neoplasm of the liver with extrahepatic growth presenting with ascending cholangitis diagnosed by endoscopic ultrasound features: a case report. AB - BACKGROUND: Mucinous cystic neoplasm of the liver with extrahepatic growth is a rare benign epithelial neoplasm of the biliary system that presents with a mass effect or is incidentally found on imaging. The tumor affects mostly the common hepatic duct, which is difficult to diagnose preoperatively by radiology, endoscopy, or cystic fluid analysis. Endoscopic ultrasound is a noninvasive tool for the evaluation of features of a cystic lesion and the extent of disease. Optimal treatment is complete tumor resection. CASE PRESENTATION: A 27-year-old Thai woman was referred to our hospital for investigation and treatment of clinical symptoms of obstructive jaundice and ascending cholangitis, as well as an unknown cause of obstruction. Multiple investigations were performed, including endoscopic retrograde cholangiography and magnetic resonance imaging. Endoscopic ultrasound showed a multiloculated cystic lesion with internal septations without communication to the bile duct, which helped to support a diagnosis of mucinous cystic neoplasm. Eventually, the pathological diagnosis made was mucinous cystic neoplasm of the bile duct. A follow-up clinical examination with imaging at 6 months revealed that the patient was asymptomatic and without recurrence. CONCLUSIONS: We report a rare case of a patient with a large mucinous cystic neoplasm of the liver with extrahepatic growth causing biliary obstruction, which was diagnosed on the basis of endoscopic ultrasound features. Following definitive diagnosis, treatment with complete surgical resection using a multidisciplinary approach was successful. PMID- 29444710 TI - A novel in vitro model for the assessment of postnatal myonuclear accretion. AB - BACKGROUND: Due to the post-mitotic nature of myonuclei, postnatal myogenesis is essential for skeletal muscle growth, repair, and regeneration. This process is facilitated by satellite cells through proliferation, differentiation, and subsequent fusion with a pre-existing muscle fiber (i.e., myonuclear accretion). Current knowledge of myogenesis is primarily based on the in vitro formation of syncytia from myoblasts, which represents aspects of developmental myogenesis, but may incompletely portray postnatal myogenesis. Therefore, we aimed to develop an in vitro model that better reflects postnatal myogenesis, to study the cell intrinsic and extrinsic processes and signaling involved in the regulation of postnatal myogenesis. METHODS: Proliferating C2C12 myoblasts were trypsinized and co-cultured for 3 days with 5 days differentiated C2C12 myotubes. Postnatal myonuclear accretion was visually assessed by live cell time-lapse imaging and cell tracing by cell labeling with Vybrant(r) DiD and DiO. Furthermore, a Cre/LoxP-based cell system was developed to semi-quantitatively assess in vitro postnatal myonuclear accretion by the conditional expression of luciferase upon myoblast-myotube fusion. Luciferase activity was assessed luminometrically and corrected for total protein content. RESULTS: Live cell time-lapse imaging, staining-based cell tracing, and recombination-dependent luciferase activity, showed the occurrence of postnatal myonuclear accretion in vitro. Treatment of co cultures with the myogenic factor IGF-I (p < 0.001) and the cytokines IL-13 (p < 0.05) and IL-4 (p < 0.001) increased postnatal myonuclear accretion, while the myogenic inhibitors cytochalasin D (p < 0.001), myostatin (p < 0.05), and TNFalpha (p < 0.001) decreased postnatal myonuclear accretion. Furthermore, postnatal myonuclear accretion was increased upon recovery from electrical pulse stimulation-induced fiber damage (p < 0.001) and LY29004-induced atrophy (p < 0.001). Moreover, cell type-specific siRNA-mediated knockdown of myomaker in myoblasts (p < 0.001), but not in myotubes, decreased postnatal myonuclear accretion. CONCLUSIONS: We developed a physiologically relevant, sensitive, high throughput cell system for semi-quantitative assessment of in vitro postnatal myonuclear accretion, which can be used to mimic physiological myogenesis triggers, and can distinguish the cell type-specific roles of signals and responses in the regulation of postnatal myogenesis. As such, this method is suitable for both basal and translational research on the regulation of postnatal myogenesis, and will improve our understanding of muscle pathologies that result from impaired satellite cell number or function. PMID- 29444711 TI - Information needs in people with diabetes mellitus: a systematic review. AB - BACKGROUND: The purpose of this study was to identify and analyse currently available knowledge on information needs of people with diabetes mellitus, also considering possible differences between subgroups and associated factors. METHODS: Twelve databases including MEDLINE, EMBASE and the Cochrane Library were searched up until June 2015. Publications that addressed self-reported information needs of people with diabetes mellitus were included. Each study was assessed by using critical appraisal tools, e.g. from the UK National Institute for Health and Care Excellence. Extraction and content analysis were performed systematically. RESULTS: In total, 1993 publications were identified and 26 were finally included. Nine main categories of information needs were identified, including 'treatment-process', 'course of disease', 'abnormalities of glucose metabolism' and 'diabetes through the life cycle'. Differences between patient subgroups, such as type of diabetes or age, were sparsely analysed. Some studies analysed associations between information needs and factors such as participation preferences or information seeking. They found, for example, that information needs on social support or life tasks were associated with information seeking in Internet forums. CONCLUSION: Information needs in people with diabetes mellitus, appear to be high, yet poorly investigated. Research is needed regarding differences between diverse diabetes populations, including gender aspects or changes in information needs during the disease course.

PMID- 29444712 TI - Physical activity as treatment for alcohol use disorders (FitForChange): study protocol for a randomized controlled trial. AB - BACKGROUND: Help-seeking for alcohol use disorders (AUDs) is low and traditional treatments are often perceived as stigmatizing. Physical activity has positive effects on mental and physical health which could benefit this population. We propose to compare the effects of aerobic training, yoga, and usual care for AUDs in physically inactive Swedish adults. METHODS: This is a three-group, parallel, single-blind, randomized controlled trial (RCT). In total, 210 adults (aged 18-75 years) diagnosed with an AUD will be invited to participate in a 12-week intervention. The primary study outcome is alcohol consumption measure by the Timeline Follow-back method and the Alcohol Use Disorders Identification Test (AUDIT). Secondary outcomes include: depression, anxiety, perceived stress, sleep quality, physical activity levels, fitness, self-efficacy, health-related quality of life, and cognition. Blood samples will be taken to objectively assess heavy drinking, and saliva to measure cortisol. Acute effects of exercise on the urge to drink alcohol, mood, and anxiety will also be assessed. DISCUSSION: The treatment potential for exercise in AUDs is substantial as many individuals with the disorder are physically inactive and have comorbid health problems. The study is the first to assess the effects of physical activity as a stand-alone treatment for AUDs. Considerable attention will be given to optimizing exercise adherence. Both the feasibility and treatment effects of exercise interventions in AUDs will be discussed. The Ethical Review Board (EPN) at Karolinska Institutet has approved the study (DNR: 2017/1380-3). TRIAL REGISTRATION: German Clinical Trials Register, ID: DRKS00012311. Registered on 26 September 2017. PMID- 29444713 TI - Evaluation of hospital outcomes: the relation between length-of-stay, readmission, and mortality in a large international administrative database. AB - BACKGROUND: Hospital mortality, readmission and length of stay (LOS) are commonly used measures for quality of care. We aimed to disentangle the correlations between these interrelated measures and propose a new way of combining them to evaluate the quality of hospital care. METHODS: We analyzed administrative data from the Global Comparators Project from 26 hospitals on patients discharged between 2007 and 2012. We correlated standardized and risk-adjusted hospital outcomes on mortality, readmission and long LOS. We constructed a composite measure with 5 levels, based on literature review and expert advice, from survival without readmission and normal LOS (best) to mortality (worst outcome). This composite measure was analyzed using ordinal regression, to obtain a standardized outcome measure to compare hospitals. RESULTS: Overall, we observed a 3.1% mortality rate, 7.8% readmission rate (in survivors) and 20.8% long LOS rate among 4,327,105 admissions. Mortality and LOS were correlated at the patient and the hospital level. A patient in the upper quartile LOS had higher odds of mortality (odds ratio = 1.45, 95% confidence interval 1.43-1.47) than those in the lowest quartile. Hospitals with a high standardized mortality had higher proportions of long LOS (r = 0.79, p < 0.01). Readmission rates did not correlate with either mortality or long LOS rates. The interquartile range of the standardized ordinal composite outcome was 74-117. The composite outcome had similar or better reliability in ranking hospitals than individual outcomes. CONCLUSIONS: Correlations between different outcome measures are complex and differ between hospital- and patient-level. The proposed composite measure combines three outcomes in an ordinal fashion for a more comprehensive and reliable view of hospital performance than its component indicators.

AB - OBJECTIVES: This study assessed the activity of thiopurine S-methyltransferase (TPMT) in Nigerians with a view to providing data on susceptibility to thiopurine toxicity, and as well generate reference activity values for clinical use. RESULTS: TPMT activity, expressed as the amount of 6MMP in ng/mL after 1 h incubation at 37 degrees C per haemoglobin (U/g Hb), varied between 2.34 and 63.50 U/g Hb in the study population. Poor metabolic phenotypes, characterised by an activity values below 8.41 U/g Hb, were observed in 20% of the study subjects. Intermediate metabolizers had activity values between 8.41 and 16.13 U/g Hb. Fast and very fast metabolizers were characterised by activity values of 16.20-56.22 and > 56.22 U/g Hb, respectively. These findings suggest that a potentially huge discordance between TPMT phenotype and genotype exist in Nigerians, and emphasizes the superiority of a prior determination of TPMT metabolic phenotype in ensuring the safety of thiopurine drug administration in the population. PMID- 29444715 TI - Porcine Wharton's jelly cells distribute throughout the body after intraperitoneal injection. AB - BACKGROUND: Wharton's jelly cells (WJCs) have multiple differentiation potentials and are easily harvested in large numbers. WJCs are well tolerated in allogeneic environments and there is a growing list of their therapeutic effects. Most therapies require administering large numbers of cells and this is generally accomplished by intravenous injection. Here, we studied the locations of porcine WJCs in immune-competent, allogeneic hosts after intraperitoneal (IP) injection. METHODS: Male porcine WJCs were administered to female neonatal piglets by IP injection. The location of transplanted cells was examined at 6 h, 24 h, and 7 days after administration using confocal microscopy and polymerase chain reaction (PCR). Transplanted cells were also retrieved from the intestines of recipients and were cultured. Previously transplanted cells were identified by fluorescence in-situ hybridization (FISH) using a Y-chromosome probe. RESULTS: Allogeneic cells were identified in the small and large intestine, stomach, liver, spleen, diaphragm, omentum, kidney, pancreas, mesenteric lymph nodes, heart, lungs, uterus, bladder, and skeletal muscle. Male cells (SRY positive) were found in cultures of cells harvested from the intestinal mucosa 1 week after administration of male porcine WJCs. CONCLUSIONS: Our results show that porcine WJCs distribute widely to the organs in immunocompetent allogeneic hosts after IP administration. They may distribute through the lymphatics initially, and a prominent site of incorporation is the mucosa of the gastrointestinal tract. In that location they could function in the niche of endogenous stem cells and provide secretory products to cells in the tissue damaged by intestinal disease. PMID- 29444716 TI - Prevalence of inadequate micronutrient intakes of Canadian long-term care residents. AB - This study determines the prevalence of inadequate micronutrient intakes consumed by long-term care (LTC) residents. This cross-sectional study was completed in thirty-two LTC homes in four Canadian provinces. Weighed and estimated food and beverage intake were collected over 3 non-consecutive days from 632 randomly selected residents. Nutrient intakes were adjusted for intra-individual variation and compared with the Dietary Reference Intakes. Proportion of participants, stratified by sex and use of modified (MTF) or regular texture foods, with intakes below the Estimated Average Requirement (EAR) or Adequate Intake (AI), were identified. Numbers of participants that met these adequacy values with use of micronutrient supplements was determined. Mean age of males (n 197) was 85.2 (sd 7.6) years and females (n 435) was 87.4 (sd 7.8) years. In all, 33 % consumed MTF; 78.2 % (males) and 76.1 % (females) took at least one micronutrient pill. Participants on a MTF had lower intake for some nutrients (males=4; females=8), but also consumed a few nutrients in larger amounts than regular texture consumers (males=4; females =1). More than 50 % of participants in both sexes and texture groups consumed inadequate amounts of folate, vitamins B6, Ca, Mg and Zn (males only), with >90 % consuming amounts below the EAR/AI for vitamin D, E, K, Mg (males only) and K. Vitamin D supplements resolved inadequate intakes for 50 70 % of participants. High proportions of LTC residents have intakes for nine of twenty nutrients examined below the EAR or AI. Strategies to improve intake specific to these nutrients are needed. PMID- 29444717 TI - Good correlation between visual analogue scale and numerical rating scale in the assessment of nasal obstruction. AB - OBJECTIVE: Results from telephone interviews may be needed to supplement those from mailed questionnaires when response rates are inadequate. This study assessed the correlation between visual analogue scale ratings used in mailed questionnaires and numerical rating scale scores used in telephone interviews. METHODS: Patients scheduled for nasal septal surgery routinely respond to a visual analogue scale of obstruction during the day and at night. In this study, they were also asked to verbally rate their sense of obstruction using whole numbers. RESULTS: There was no significant difference between visual analogue scale and numerical rating scale obstruction scores. CONCLUSION: Ratings of nasal obstruction obtained with a numerical rating scale in telephone interviews are comparable to visual analogue scale scores in mailed questionnaires. PMID- 29444718 TI - Routine use of salivary bypass tubes in laryngectomy patients: systematic review. AB - BACKGROUND: Pharyngocutaneous fistula is a cause of significant morbidity following laryngectomy. Routine use of salivary bypass tubes during laryngectomy has been proposed to reduce the incidence of fistulae and neopharyngeal strictures. METHOD: Following a systematic search of Embase, Medline and Cochrane databases (1946 - current), included articles were assessed for bias according to the Cochrane Handbook for Systematic Reviews of Interventions. RESULTS: Three case-control trials showed reduced pharyngocutaneous fistula rates with the use of salivary bypass tubes; six case series reported widely varied fistula rates. With regards to stricture rates, the largest case-control trial found no improvement with salivary bypass tube use. No fatal adverse events were observed among the 204 patients who received a salivary bypass tube. CONCLUSION: Low-level evidence suggests salivary bypass tubes may reduce the incidence of fistula in high-risk patient groups. A robust randomised controlled trial, or large, multicentre cohort studies, are needed to further examine this intervention. PMID- 29444719 TI - The significance of atherosclerosis in hypertensive patients with epistaxis. AB - BACKGROUND: The relationship between hypertension and epistaxis is controversial and poorly understood. The present research investigated atherosclerosis as a potential risk factor in hypertensive patients with epistaxis. METHODS: A prospective study of 141 hypertensive patients with epistaxis was conducted. The laboratory tests included full blood count, lipid profile and coagulation profile. All patients underwent funduscopic examination of the eye and were classified in terms of four retinopathy grades. RESULTS: There were strong positive correlations between the number of nosebleeds and retinopathy grade and low-density lipoprotein cholesterol level. There were weak correlations between the number of nosebleeds and blood pressure readings and triglycerides levels. Patients with grade III retinopathy, suggesting atherosclerosis, suffered from more frequent nosebleeds than other patients. CONCLUSION: Atherosclerosis is one of the potential risk factors in hypertensive patients with epistaxis. This may have an impact on treatment choices. PMID- 29444720 TI - MATERNAL SENSITIVITY AND PERFORMANCE AND VERBAL INTELLIGENCE IN LATE CHILDHOOD AND ADOLESCENCE. AB - The aim of this study was to investigate the association between maternal sensitivity and offspring intelligence in late childhood and adolescence. Secondary data (N=117) from the Block and Block (2006a, b) 30-year longitudinal study of Californian children, which began in the late 1960s, was used to test the hypothesis that maternal sensitivity in childhood would be predictive of late childhood and adolescent intelligence. Correlational analyses revealed that maternal sensitivity, as judged by raters viewing mother's interactions with their children in a set of four joint structured cognitive tasks when the child was 5 years of age, was associated with verbal and performance IQ test scores when the children were ages 11 and 18. Using hierarchical regression to control for child sex, socioeconomic status, child temperament, child baseline IQ (as measured at age 4), mother's level of education and mother's emotional nurturance, it was found that the maternal sensitivity and child and adolescent IQ association held for verbal, but not performance IQ. Furthermore, a pattern emerged in which the association between maternal sensitivity and verbal IQ was stronger for adolescents with a lower baseline IQ. The results suggest that maternal sensitivity is associated with offspring verbal intelligence and that this association holds when numerous variables are accounted for. Additionally, this association may be stronger for children with lower IQs. PMID- 29444722 TI - An event-semantic account of spatial modification in the acquisition of Mandarin. AB - This study investigates Mandarin-speaking children's knowledge of event semantics in interpreting spatial modifiers with zai 'at' after a posture verb or before a placement verb. The event-semantic principles investigated include subevent modification (Parsons, 1990) and aspect shift (Fong, 1997). We conducted an experimental study using modified forced choice, video choice, and elicited production techniques with five groups of children (two- to six-year-olds) and an adult control group. Three-year-olds were sensitive to the ambiguity of zai-PPs with placement verbs and posture verbs, suggesting guidance from principles of aspect shift and subevent modification. On the other hand, distributional properties of the input play a role in acquiring the interpretation and word order of zai: e.g., four-year-olds significantly differed from adults in accepting non-target V-zai sentences, as some verb classes can take postverbal prepositional phrases with zai while others cannot in adult usage. PMID- 29444723 TI - Evaluation of the Xpert MTB/RIF Performance on Tissues: Potential Impact on Airborne Infection Isolation at a Tertiary Cancer Care Center. AB - OBJECTIVES In this study, we sought to evaluate the performance of the Xpert MTB/RIF (Cepheid) assay for the detection of Mycobacterium tuberculosis (MTB) complex DNA on fresh and formalin-fixed, paraffin-embedded (FFPE) tissue specimens from oncology patients in an area with a low prevalence of tuberculosis. We also aimed to retrospectively assess the potential impact of Xpert MTB/RIF on the duration of airborne infection isolation (AII). SETTING A 473-bed, tertiary-care cancer center in New York City. DESIGN A total of 203 tissue samples (101 FFPE and 102 fresh) were tested using Xpert MTB/RIF, including 133 pulmonary tissue samples (65.5%) and 70 extrapulmonary tissue samples (34.5%). Acid-fast bacilli (AFB) culture was used as the diagnostic gold standard. The limit of detection (LOD) and reproducibility were also evaluated for both samples types using contrived specimens. The potential impact of the Xpert MTB PCR assay on tissue samples from AII patients on AII duration was retrospectively assessed. RESULTS Using the Xpert MTB/RIF for fresh tissue specimens, the sensitivity was 50% (95% CI, 1.3%-98.7%) and the specificity was 99% (95% CI, 94.5%-99.9%). For FFPE tissue specimens, the sensitivity was 100% (95% CI, 63.1%-100%) and the specificity was 98.3% (95% CI, 95.5%-100%. The LOD was 103 colony-forming units (CFU)/mL for both fresh and FFPE tissue specimens, and the Xpert MTB/RIF was 100% reproducible at concentrations 10 times that of the LOD. With an expected turnaround time of 24 hours, the Xpert MTB PCR could decrease the duration of AII from a median of 8 days to a median of 1 day. CONCLUSIONS The Xpert MTB/RIF assay offers a valid option for ruling out Mycobacterium tuberculosis complex (MTBC) on tissue samples from oncology patients and for minimizing AII resource utilization.

PMID- 29444721 TI - Psychological treatments delivered by community health workers in low-resource government health systems: effectiveness of group interpersonal psychotherapy for caregivers of children affected by nodding syndrome in Uganda. AB - BACKGROUND: Despite increasing evidence for the benefits of psychological treatments (PTs) in low- and middle-income countries, few national health systems have adopted PTs as standard care. We aimed to evaluate the effectiveness of a group interpersonal psychotherapy (IPT-G) intervention, when delivered by lay community health workers (LCHWs) in a low-resource government health system in Uganda. The intended outcome was reduction of depression among caregivers of children with nodding syndrome, a neuropsychiatric condition with high morbidity, mortality and social stigma. METHODS: A non-randomized trial design was used. Caregivers in six villages (n = 69) received treatment as usual (TAU), according to government guidelines. Caregivers in seven villages (n = 73) received TAU as well as 12 sessions of IPT-G delivered by LCHWs. Primary outcomes were caregiver and child depression assessed at 1 and 6 months post-intervention. RESULTS: Caregivers who received IPT-G had a significantly greater reduction in the risk of depression from baseline to 1 month [risk ratio (RR) 0.25, 95% confidence interval (CI) 0.10-0.62] and 6 months (RR 0.33, 95% CI 0.11-0.95) post intervention compared with caregivers who received TAU. Children of caregivers who received IPT-G had significantly greater reduction in depression scores than children of TAU caregivers at 1 month (Cohen's d = 0.57, p = 0.01) and 6 months (Cohen's d = 0.54, p = 0.03). Significant effects were also observed for psychological distress, stigma and social support among caregivers. CONCLUSION: IPT-G delivered within a low-resource health system is an effective PT for common mental health problems in caregivers of children with a severe neuropsychiatric condition and has psychological benefits for the children as well. This supports national health policy initiatives to integrate PTs into primary health care services in Uganda. PMID- 29444724 TI - Early postoperative remodelling following repair of tetralogy of Fallot utilising unsedated cardiac magnetic resonance: a pilot study. AB - : IntroductionThe right ventricular adaptations early after surgery in infants with tetralogy of Fallot are important to understand the changes that occur later on in life; this physiology has not been fully delineated. We sought to assess early postoperative right ventricular remodelling in patients with tetralogy of Fallot by cardiac MRI.Materials and methodSubjects with tetralogy of Fallot under 1 year of age were recruited following complete surgical repair for tetralogy of Fallot. Protocol-based cardiac MRI to assess anatomy, function, and flows was performed before hospital discharge using the feed and sleep technique, an unsedated imaging technique. RESULTS: MRI was completed in 16 subjects at a median age of 77 days (interquartile range 114). There was normal ventricular ejection fraction and indexed right ventricular end-diastolic volume (48+/-13 cc/m2), but elevated right ventricular mass (z score 6.2+/-2.4). Subjects requiring a transannular patch or right ventricle to pulmonary artery conduit had moderate pulmonary insufficiency (regurgitant fraction 27+/-16%).DiscussionEarly right ventricular remodelling after surgical repair for tetralogy of Fallot is characterised by significant pulmonary regurgitation, right ventricular hypertrophy, and lack of dilation. Performing cardiac MRI using the feed and sleep technique is feasible in infants younger than 5 months. These results might open new avenues to study longitudinal right ventricular changes in tetralogy of Fallot and to further explore the utility of unsedated MRI in patients with other types of CHDs.

PMID- 29444726 TI - Resting-state thalamic dysconnectivity in schizophrenia and relationships with symptoms. AB - BACKGROUND: Schizophrenia (SZ) is a severe neuropsychiatric disorder associated with disrupted connectivity within the thalamic-cortico-cerebellar network. Resting-state functional connectivity studies have reported thalamic hypoconnectivity with the cerebellum and prefrontal cortex as well as thalamic hyperconnectivity with sensory cortical regions in SZ patients compared with healthy comparison participants (HCs). However, fundamental questions remain regarding the clinical significance of these connectivity abnormalities. METHOD: Resting state seed-based functional connectivity was used to investigate thalamus to whole brain connectivity using multi-site data including 183 SZ patients and 178 matched HCs. Statistical significance was based on a voxel-level FWE corrected height threshold of p < 0.001. The relationships between positive and negative symptoms of SZ and regions of the brain demonstrating group differences in thalamic connectivity were examined. RESULTS: HC and SZ participants both demonstrated widespread positive connectivity between the thalamus and cortical regions. Compared with HCs, SZ patients had reduced thalamic connectivity with bilateral cerebellum and anterior cingulate cortex. In contrast, SZ patients had greater thalamic connectivity with multiple sensory-motor regions, including bilateral pre- and post-central gyrus, middle/inferior occipital gyrus, and middle/superior temporal gyrus. Thalamus to middle temporal gyrus connectivity was positively correlated with hallucinations and delusions, while thalamus to cerebellar connectivity was negatively correlated with delusions and bizarre behavior. CONCLUSIONS: Thalamic hyperconnectivity with sensory regions and hypoconnectivity with cerebellar regions in combination with their relationship to clinical features of SZ suggest that thalamic dysconnectivity may be a core neurobiological feature of SZ that underpins positive symptoms.

PMID- 29444728 TI - The Long-Term Effects of the Deepwater Horizon Oil Spill on Women's Depression and Mental Distress. AB - OBJECTIVE: The purpose of the study is to describe changes in mental health among women following an oil spill and to examine their association with the Deepwater Horizon oil spill (DHOS). METHODS: The Women and Their Children's Health study followed 2038 women in Louisiana after the DHOS. Subjects were interviewed in 2012-2014 and 2014-2016. Oil spill exposure was characterized using survey items about economic and physical exposures. Outcomes were depressive symptoms and mental distress. RESULTS: After adjustment for relevant demographics, depressive symptoms increased over 2 time points following the DHOS, whereas symptoms of mental distress decreased. For every year increase in time since the DHOS, the rate ratio for depressive symptoms increased by a factor of 1.08. In contrast, the rate ratio for mental distress decreased by a factor of 0.97. In addition, initial associations between economic and physical exposure to the DHOS persisted up to 6 years after the spill; women who were more highly exposed experienced higher levels of depressive symptoms (rate ratios ranged from 1.08 to 1.11) and mental distress (rate ratios from 1.05 to 1.11) at each time point than women who were less exposed. CONCLUSION: A better understanding of recovery patterns following an oil spill can help direct critical mental health response efforts. (Disaster Med Public Health Preparedness. 2018;page 1 of 8).

PMID- 29444733 TI - Medically Attended Catheter Complications Are Common in Patients With Outpatient Central Venous Catheters. AB - OBJECTIVE Outpatient central venous catheters (CVCs) are being used more frequently; however, data describing mechanical complications and central-line associated bloodstream infections (CLABSI) in the outpatient setting are limited. We performed a retrospective observational cohort study to understand the burden of these complications to elucidate their impact on the healthcare system. METHODS Data were retrospectively collected on patients discharged from Vanderbilt University Medical Center with a CVC in place and admitted into the care of Vanderbilt Home Care Services. Risk factors for medically attended catheter-associated complications (CACs) and outpatient CLABSIs were analyzed. RESULTS A CAC developed in 143 patients (21.9%), for a total of 165 discrete CAC events. Among these, 76 (46%) required at least 1 visit to the emergency department or an inpatient admission, while the remaining 89 (54%) required an outpatient clinic visit. The risk for developing a CAC was significantly increased in female patients, patients with a CVC with >1 lumen, and patients receiving total parenteral nutrition. The absolute number of CLABSIs identified in the study population was small at 16, or 2.4% of the total cohort. CONCLUSIONS Medically attended catheter complications were common among outpatients discharged with a CVC, and reduction of these events should be the focus of outpatient quality improvement programs.

AB - The aim of this experiment was to study the effect of total replacement of oat hay by rosemary distillation residues (RR) on growth, carcass characteristics and meat quality of Barbarine lambs. A total of 21 lambs were divided into three groups. The control group (C) was offered 600 g of oat hay; the RR87 and RR60 groups received 600 g of pellets containing 87% and 60% of RR, respectively. The CP content was 9% and 14% for RR87 and RR60, respectively. All animals were supplemented by 600 g of concentrate. After 77 days of fattening, lambs were slaughtered. The DM and CP intakes were significantly increased with RR diets. The average daily gain was higher (P<0.001), while the feed conversion rate was lower for RR60 and RR87 than C group. The dressing percentage was similar for all groups. The tissular (muscle, fat and bone) and the regional (leg, shoulder, etc.) carcass composition did not differ among groups. The bony organs and gut weights were similar among groups, while functional ones (skin, liver, kidney and testicles) were significantly heavier for both RR groups than control. The ultimate pH, water cooking loss and color variables were similar among groups and the chemical composition (protein, fat, myoglobin, collagen and iron) did not differ also among groups. These results revealed the opportunity of RR use in fattening lambs without adverse effects on carcass and meat characteristics. Moreover, 9% CP in RR pellets are enough given the same growth performance recorded as that of RR with 14% CP. PMID- 29444735 TI - Short Assessment of Health Literacy (SAHL) in Portugal: development and validation of a self-administered tool. AB - The goal of this study was to adapt, improve and validate a short, self administered health literacy assessment tool for European Portuguese-speaking adults. Health literacy tools are of great importance to health authorities and professionals, as low or inadequate health literacy, that is, a limited capacity to handle health-related information, is associated with higher morbidity and mortality. The 18-item Short Assessment of Health Literacy for Brazilian Portuguese-speaking adults (SAHLPA-18) was adapted into European Portuguese. The European Portuguese tool (SAHLPA-23) includes five additional items. The SAHLPA 23 was tested in a convenience sample of 503 participants from two Portuguese regions. Socio-demographic data, literacy and cognitive indicators were collected. Participants also completed a questionnaire on comprehension of written health materials. Construct validity was assessed through correlations between SAHLPA-23 scores and education, literacy, and cognitive variables and score on the comprehension questionnaire. The psychometric properties of the new tool were compared with those of the SAHLPA-18. The mean SAHLPA-18 and SAHLPA-23 scores were 13.9 (77.2%; SD=2.9) and 18.3 (79.6%; SD=3.8), respectively. Both tools showed adequate reliability (Cronbach's alpha>0.7). SAHLPA-23 was more highly correlated with all study variables than SAHLPA-18. Although both instruments displayed acceptable discriminative power, SAHLPA-23 had better accuracy than SAHLPA-18 (DeLong's method: DeltaAUC=0.09, Z=3.36; P<0.001). The SAHLPA-23 is an independent, feasible and innovative tool for estimation of health literacy in the Portuguese adult population.

AB - : Aim To explore the experiences and challenges for residential care home staff when managing the healthcare needs of their residents, in particular those living with dementia. BACKGROUND: Increasing number of older people, with complex health and social care needs are living in residential care homes. Yet there is limited appreciation of why staff sometimes struggle to manage residents' healthcare needs, or understanding of their working relationship with district nurses (DNs), whose responsibility it is to provide nursing support. METHODS: This PhD study, in a metropolitan area in the United Kingdom, was conducted by an experienced DN and involved three phases. This paper focuses on the first two phases. Phase 1 data included: semi-structured interviews (n=8), reflective field notes based on non-participant observation, documentary analysis of policies, procedures and assessment tools and other contextual data from one care home (case study site). The practitioner researcher reflected on the findings from the case study, in relation to her own knowledge and experience as a DN, focusing in particular on findings that were familiar, or which surprised. In Phase 2 she fed these findings back to other care homes (n=11) to check whether the findings from the single case study were unique or resonated with others. She gathered their feedback through semi-structured interviews with senior care staff (n=14). Data were analysed using thematic data analysis. Findings Findings highlight the complexity facing residential care homes: high levels of healthcare needs amongst residents, the demands of caring for residents living with dementia, variations in the knowledge and skill set of care staff, inequity in the level of healthcare support, the challenges of building a good relationship with DNs, and funding pressures facing care homes. Implications Any, or all of these factors can prevent care home staff from managing the healthcare needs of their residents. PMID- 29444737 TI - Offspring birth weight and cardiovascular mortality among parents: the role of cardiovascular risk factors. AB - An inverse association between offspring birth weight (BW) and higher risk of parental cardiovascular disease (CVD) mortality and morbidity has been reported. Shared environmental, genetic and intrauterine factors may be responsible for explaining these associations. We studied the role of parental CVD risk factors in the association between offspring BW and CVD mortality among mothers and fathers. All births registered in Medical Birth Registry Norway (1967-2012) were linked to three health surveys, National Educational Registry and Cause of Death Registry. Number of births with information of parental CVD risk factors available for the analyses was 1,006,557 (520,670 for mothers and 485,887 for fathers). Cox proportional hazards regression models were used, following CVD deaths in parents from 1974 to 2012. An inverse association between offspring BW and CVD mortality was observed among both parents: hazard ratio 1.60 (1.44-1.75) for mothers and 1.16 (1.10-1.23) for fathers. Among mothers, adjustment for smoking, triglycerides and diabetes reduced the risk to 1.36 (1.25-1.52), 1.57 (1.43-1.73) and 1.58 (1.43-1.79), respectively. Adjustment for diastolic blood pressure (DBP) and systolic blood pressure (SBP) both reduced the risk to 1.53 (1.37-1.66). Among fathers, adjustments for smoking, DBP, SBP reduced the risk to 1.08 (1.02-1.15), 1.13 (1.06-1.19) and 1.14 (1.08-1.22), respectively. Triglycerides and diabetes both reduced the risk to 1.15 (1.09-1.12). Our results indicate that shared environmental factors might be important in the association. A stronger association in mothers suggest that intrauterine factors also are at play. PMID- 29444738 TI - The Influence of Traffic, Area Location, and Other Factors on Operating Room Microbial Load. AB - OBJECTIVE To determine how the movement of patients, equipment, materials, staff, and door openings within the operating room (OR) affect microbial loads at various locations within the OR. DESIGN Observation and sampling study. SETTING Academic health center, public hospital. METHODS We first analyzed 27 videotaped procedures to determine the areas in the OR with high and low numbers of people in transit. We then placed air samplers and settle plates in representative locations during 21 procedures in 4 different ORs during 2 different seasons of the year to measure microbial load in colony-forming units (CFU). The temperature and humidity, number of door openings, physical movement, and the number of people in the OR were measured for each procedure. Statistical analysis was conducted using hierarchical regression. RESULTS The microbial load was affected by the time of year that the samples were taken. Both microbial load measured by the air samplers and by settle plates in 1 area of the OR was correlated with the physical movement of people in the same area but not with the number of door openings and the number of people in the OR. CONCLUSIONS Movement in the OR is correlated with the microbial load. Establishing operational guidelines or developing OR layouts that focus on minimizing movement by incorporating desirable internal storage points and workstations can potentially reduce microbial load, thereby potentially reducing surgical site infection risk.

AB - OBJECTIVE: To analyse the content and extent of marketing of ultra-processed food products (UPP) and their brand pages on Facebook, which are highly accessed by Brazilians. DESIGN: Descriptive. SETTING: Sixteen UPP brand pages on Facebook were selected from 250 pages that were the most liked by Brazilians in October 2015. SUBJECTS: We analysed the frequency of 'likes' and members 'talking about' each one of the pages, in addition to fifteen marketing techniques used in the previous year (September 2014 to October 2015). The number of posts, likes, 'shares' and 'commentaries', and the mean number of likes, shares and commentaries per post, were collected for one month, from 23 September to 23 October 2015. RESULTS: The two most liked pages were: Coke(r) (93 673 979 likes) and McDonald's(r) (59 749 819 likes). Regarding the number of people talking about the pages, McDonald's led with 555 891 commentaries, followed by Coke (287 274), Burger King(r) (246 148) and Kibon(r) (244 523). All pages used marketing techniques, which included photos, user conversations, presence of brand elements and links. Videos were observed on 93.8 % of the pages; promotions on 68.8 %; and celebrities on 62.5 %. In one month, Garoto(r), Outback(r) and Coke were brands that published more than one post per day. Kibon achieved the highest ratio of likes per post (285 845.50) and Burger King had the highest mean shares per post (10 083.93), including commentaries per post (7958.13). CONCLUSIONS: UPP marketing is extensively used on Facebook pages and is highly accessed by Brazilians, with UPP companies employing a diversity of marketing strategies. PMID- 29444740 TI - Associations between modifiable lifestyle factors and multidimensional cognitive health among community-dwelling old adults: stratified by educational level. AB - : ABSTRACTBackground:Cognition is multidimensional, and each domain plays a unique and crucial part in successful daily life engagement. However, less attention has been paid to multi-domain cognitive health for the elderly, and the role of lifestyle factors in each domain remains unclear. METHODS: We conducted a cross-sectional study of 3,230 older adults aged 60+ years in Xiamen, China, in 2016. The Montreal Cognitive Assessment (MoCA) was used to measure general cognition and six specific sub-domains. To account for educational effects, we adjusted the MoCA score and divided respondents into three education-specific groups (low, moderate, and high education groups with <=5, 6~8, and >=9 years of education, respectively). A series of proportional odds models were used to detect the associations between two categories of lifestyle factors - substance abuse (cigarette and alcohol) and leisure activity (TV watching, reading, smartphone use, social activity, and exercise) - and general cognition and the six sub-domains in those three groups. RESULTS: Among the 3,230 respondents, 2,617 eligible participants were included with a mean age of 69.05 +/- 7.07 years. Previous or current smoking/drinking was not associated with MoCA scores in the whole population, but unexpectedly, the ex-smokers in the low education group performed better in general cognition (OR = 2.22) and attention (OR = 2.05) than their never-smoking counterparts. Modest TV watching, reading, and smartphone use also contributed to better cognition among elderly participants in the low education group. For the highly educated elderly, comparatively longer reading (>3.5 hours/week) was inversely associated with general cognition (OR = 0.53), memory (OR = 0.59), and language (OR = 0.54), while adequate exercise (5~7 days/week) was positively related to these factors with OR = 1.48, OR = 1.49, and OR = 1.53, respectively. For the moderately educated elderly, only modest reading was significantly beneficial. CONCLUSIONS: Lifestyle factors play different roles in multidimensional cognitive health in different educational groups, indicating that individual intervention strategies should be designed according to specific educational groups and different cognitive sub-domains.

PMID- 29444742 TI - Effects of Disaster Damage and Working Conditions on Mental Health Among Public Servants 16 Months After the Great East Japan Earthquake. AB - OBJECTIVE: To explore whether stressors after a disaster have later effects on the mental health of public servants who engage in disaster response and to estimate the proportion of those experiencing persistent mental distress. METHODS: We analyzed the data of health surveys conducted in Miyagi Prefecture for all prefectural public servants at 2, 7, and 16 months after the Great East Japan Earthquake (n=3174). We investigated relationships between mental distress (defined as K6>=10) at 16 months after the earthquake and earthquake damage and working conditions at 2 months. We also calculated the proportion of participants who scored K6>=10 on all 3 surveys. RESULTS: The experience of living someplace other than one's own home was significantly related with mental distress at 16 months after the earthquake. Few participants consistently scored K6>=10 throughout all 3 surveys. CONCLUSIONS: The effects of stressors in the aftermath of a disaster could remain for a long time. Few public servants experienced persistent mental distress. Disaster Med Public Health Preparedness. 2018;12:622 630. PMID- 29444743 TI - Tumor suppressive microRNA-708 targets Notch1 to suppress cell proliferation and invasion in gastric cancer. AB - Growing evidence demonstrated that numerous microRNAs (miRNAs) may participate in the regulation of gastric carcinogenesis and progression. This phenomenon suggests that gastric cancer-related miRNAs can be identified as effective therapeutic targets for this disease. MiRNA-708 (miR-708) has recently been reported to be aberrantly expressed in several types of cancer and contribute to carcinogenesis and progression. However, the expression level, biological roles and underlying mechanisms of miR-708 in gastric cancer are poorly understood. Here, we found that miR-708 was down-regulated in gastric cancer tissues and cell lines. Down-regulated miR-708 expression was significantly associated with lymphatic metastasis, invasive depth and TNM stage. Further investigation indicated that ectopic expression of miR-708 prohibited cell proliferation and invasion in gastric cancer. Bioinformatics analysis showed that Notch1 was a potential target of miR-708. Notch1 was further confirmed as a direct target gene of miR-708 in gastric cancer by luciferase reporter assay, reverse transcriptionquantitative polymerase chain reaction and Western blot analysis. Furthermore, an inverse association was found between miR-708 and Notch1 mRNA level in gastric cancer tissues. In addition, restored Notch1 expression rescued the inhibitory effects on gastric cancer cell proliferation and invasion induced by miR-708 overexpression. Our findings highlight the tumor suppressive roles of miR-708 in gastric cancer and suggest that miR708 may be investigated as a novel target for gastric cancer treatment. PMID- 29444744 TI - Overexpression of Pyruvate dehydrogenase E1a subunit Inhibits Warburg effect and Induces Cell Apoptosis through Mitochondria-mediated Pathway in Hepatocellular Carcinoma. AB - Most cancers rely disproportionately on glycolysis for energy even in the presence of adequate oxygen supply, a condition known as "aerobic glycolysis", or the "Warburg effect". Pyruvate dehydrogenase E1a subunit (PDHA1) is one of main factors for metabolic switch from oxidative phosphorylation (OXPHOS) to aerobic glycolysis and has been suggested to be closely associated with tumorigenesis. Here we observed that PDHA1 protein was reduced in hepatocellular carcinoma (HCC) specimens by immunohistochemistry and western blot, which was significantly associated with poor overall survival. To further analyze the function of PDHA1 in cancer cells, it was up-regulated in HCC cell line SMMC-7721 and HepG2. The results demonstrated that overexpression of PDHA1 gene inhibited aerobic glycolysis with lower lactate via increased PDH activity, meanwhile mitochondrial OXPHOS was enhanced accompanied with higher ATP and lower glucose consumption. We also found that apoptosis was promoted and intrinsic pathway proteins was increased in PDHA1 overexpressing cells. Collectively, our data indicate that reduced PDHA1 protein expression is associated with poor clinical outcome HCC cancers. Up-regulated PDHA1 gene expression can inhibit Warburg effect and enhanced mitochondria-mediated apoptosis pathway. PMID- 29444745 TI - MicroRNA-598 Inhibits Cell Proliferation and Invasion of Glioblastoma by Directly Targeting Metastasis Associated in Colon Cancer-1 (MACC1). AB - The dysregulation of microRNA (miRNA) expression is closely related with tumorigenesis and tumor development in glioblastoma (GBM). In this study, we found that miRNA-598 (miR-598) expression was significantly downregulated in GBM tissues and cell lines. Restoring miR-598 expression inhibited cell proliferation and invasion in GBM. Moreover, we validated that metastasis associated in colon cancer-1 (MACC1) is a novel target of miR-598 in GBM. Restoring MACC1 expression reversed the inhibitory effects of miR-598 overexpression on GBM cells. In addition, miR-598 overexpression suppressed Met/AKT pathway activation in GBM. Our results provided compelling evidence that miR-598 serves tumor-suppressive roles in GBM and that its antioncogenic effects are mediated chiefly through the direct suppression of MACC1 expression and regulation of the Met/AKT signaling pathway. Therefore, miR-598 is a potential target in the treatment of GBM. PMID- 29444746 TI - Using marijuana, drinking alcohol or a combination of both: the association of marijuana, alcohol and sexual risk behaviour among adolescents. AB - : Background Although the association between alcohol use and sexual risk behaviour has been well-documented, there is little understanding of whether marijuana use alone or combining marijuana with alcohol use contributes to sexual risk behaviour among adolescents. METHODS: A diverse sample of sexually active adolescents (n = 616) aged 12-18 years (50.32% Hispanic; 31.17% Black) completed a survey on alcohol use, marijuana use and sexual risk behaviour during a visit to a primary care clinic. RESULTS: Adolescents were more likely to report having had two or more sexual partners in the past 3 months if they reported using both alcohol and marijuana (OR=3.90, P<0.0001), alcohol alone (OR=2.51, P<0.0001) or marijuana alone (OR=1.89, P<0.001) compared with adolescents who reported no use during the past month. Adolescents were more likely to report having both two or more partners and condomless sex if they used both alcohol and marijuana (OR=3.19, P<0.001) or alcohol alone (OR=3.41, P<0.01) in the past month compared with adolescents who reported using marijuana alone or had no use of either. CONCLUSIONS: Providers should screen for both alcohol and marijuana use among adolescents and discuss how use of alcohol or alcohol in conjunction with marijuana may be associated with sexual risk behaviours. PMID- 29444747 TI - HIV susceptibility among clients of female sex workers in Indonesia: a qualitative inquiry. AB - : Background The spread of HIV infection among men in Indonesia continues to increase every year. Clients of female sex workers (FSWs) are a group at higher risk of acquiring HIV infection due to their frequent engagement in sexual acts with sex workers. This study aimed to identify factors of susceptibility to HIV infection among clients of FSWs. METHODS: A qualitative inquiry using one-on-one in-depth interviews was conducted in the Belu and Malaka districts of Indonesia from January to April 2017. The study participants (n =42) were the clients of FSWs recruited using the snowball sampling technique. The inclusion criteria were: being a client of FSWs and being aged 18 years or more. Data were analysed using a framework analysis. RESULTS: Findings were grouped into two main emerging themes that included behavioural and socioeconomic factors. Behavioural factors that mediated HIV susceptibility among clients of FSWs were: frequent engagement in unsafe sex with multiple sex workers; low perceptions of the relevance of available HIV and AIDS services and limited access to these services; and HIV stigma or fear of being labelled as HIV positive. Socioeconomic factors included: participants' economic situation; and individuals' household responsibility and ability to afford FSWs services. CONCLUSIONS: The study results indicate the need to reformulate and improve HIV and AIDS-related services, including increasing the level of availability of HIV service points and the dissemination of knowledge and information about HIV and AIDS and condom use and making them accessible to both FSWs and their clients in Belu and Malaka districts. PMID- 29444748 TI - Aortopulmonary collaterals in neonates with d-transposition of the great arteries - Clinical significance early after arterial switch operation. AB - OBJECTIVES: Purpose of this study is to evaluate the clinical significance of major aortopulmonary collateral arteries (MAPCAs) during the early postoperative course after arterial switch operation (ASO) in d-transposition of the great arteries (dTGA). METHODS: Clinical data of 98 patients with simple dTGA between January 2007 and December 2016 at the University Children's Hospital Zurich, Switzerland were analyzed retrospectively. RESULTS: 37 from 98 patients (38%) required cardiac catheterization (CC) due to an early complicated postoperative course or difficult coronary transfer due to special coronary anatomy. In 15 (15%) patients, hemodynamically relevant MAPCAs were found during CC and coil embolization was performed. Patients with relevant MAPCAs had a significantly longer PICU stay (7 versus 6 days, p = 0.021), longer hospital stay (41 versus 27 days, p = 0.005), longer mechanical ventilation time (5 versus 3 days, p = 0.005), longer need for inotropic support (5 versus 4 days, p = 0.001) and delayed chest closure time (3 versus 2 days, p = 0.030) in those in whom it was left open in comparison to all other patients. In patients having CC, pre-surgery oxygen saturation was significantly lower in patients with relevant MAPCAs (58% vs 70%, p 0.019). Echocardiography had a sensitivity of 53% and a specificity of 100% in detecting relevant MAPCAs, accurately. CONCLUSIONS: MAPCAs are frequently found in dTGA patients and can be associated with lower baseline oxygen saturation and a prolonged postoperative course after ASO. Transthoracic echocardiography cannot replace CC as diagnostic tool. If significant MAPCAs are suspected, early CC should be performed for diagnostic and therapeutic reasons. PMID- 29444749 TI - Microbiological diagnosis of adult tuberculous meningitis in a ten-year cohort in Indonesia. AB - We evaluated microbiological diagnosis of tuberculous (TB) meningitis in a referral hospital in Indonesia. Over a ten-year period, we examined cerebrospinal fluid (CSF) samples of 1180 adult meningitis suspects. Sensitivity of different methods was compared, and results were stratified for HIV status, disease severity, and CSF volume. TB meningitis was bacteriologically confirmed in 501 patients. Using clinical diagnosis as reference standard (n = 713), sensitivity of different methods was 12.2% (86/703) for microscopy, 42% (73/174) for Xpert MTB/RIF, 46.0% (163/354) for solid culture, 48.8% (332/680) for liquid culture, and 64.0% (212/331) for in-house PCR. Head to head comparisons in 654 patients showed a higher yield of in-house PCR (32.3%) compared to culture (15.6%, P < 0.01). Microscopic observation of drug susceptibility (MODS) culture more rapidly became positive compared to other culture methods. Yield of culture was lower in HIV-infected (39/105) than in HIV-negative patients (N = 316/585; P < 0.01). Molecular and culture methods gave higher yields in patients with more severe disease (P < 0.01). CSF volume of >=6 ml increased the yield of culture (42.8% versus 12.1% for CSF <6 ml, P < 0.01) and ZN-microscopy (18.3% versus 1.9% for CSF <6 ml, P < 0.01). CSF centrifugation had no clear effect on sensitivity of Xpert MTB/RIF. ZN-microscopy lacks sensitivity for diagnosis of TB meningitis. For molecular assays, in-house IS6110-PCR is more sensitive than Xpert MTB/RIF. MODS culture has a clear advantage in terms of speed. Large CSF volumes are necessary for all tests. The effect of CSF processing for Xpert MTB/RIF needs further study. PMID- 29444750 TI - Structures and properties of porphyrin-based film materials part I.

PMID- 29444751 TI - Management of dyspepsia-The role of the ED Observation unit to optimize patient outcomes. AB - BACKGROUND: Dyspepsia is a common complaint that can confer significant burden on one's quality of life and may also be associated with serious underlying conditions. The objective of this study was to determine if patients admitted to the emergency department observation unit (EDOU) for severe or persistent dyspepsia would have cost effective management in terms of investigations performed, length and cost of hospital stay. The secondary objective was to determine if any patient characteristics could predict a need for admission to the inpatient unit. METHODS: Retrospective chart reviews of patients admitted to the EDOU under the Dyspepsia protocol between January 2008 and August 2014 were conducted. Baseline demographics, investigations performed, outcomes related to EDOU stay, admission and 30-day re-presentation outcomes were recorded. RESULTS: A total of 1304 patients were included. Median length of stay was 1day. Cumulative bed-saved days were 38 per month. Two hundred eighteen (16.7%) patients required admission to the inpatient service for further management, while 533 (40.9%) and 313 (24.0%) patients underwent esophagogastroduodenoscopy and hepatobiliary ultrasonography, respectively. No major adverse events were attributed to the EDOU admissions or delays in treatment. No significant clinically relevant factors were associated with a need for admission from the EDOU to the inpatient unit. Median cost of the EDOU admission was approximately one-third that of a similar admission to the inpatient unit. CONCLUSION: The EDOU is an appropriate setting to facilitate investigations and treatment of patients with dyspepsia with considerable bed-saved days. PMID- 29444752 TI - A review of international pharmacy-based minor ailment services and proposed service design model. AB - BACKGROUND: The need to consider sustainable healthcare solutions is essential. An innovative strategy used to promote minor ailment care is the utilisation of community pharmacists to deliver minor ailment services (MASs). Promoting higher levels of self-care can potentially reduce the strain on existing resources. AIM: To explore the features of international MASs, including their similarities and differences, and consider the essential elements to design a MAS model. METHODS: A grey literature search strategy was completed in June 2017 to comply with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses standard. This included (1) Google/Yahoo! search engines, (2) targeted websites, and (3) contact with commissioning organisations. Executive summaries, table of contents and title pages of documents were reviewed. Key characteristics of MASs were extracted and a MAS model was developed. RESULTS: A total of 147 publications were included in the review. Key service elements identified included eligibility, accessibility, staff involvement, reimbursement systems. Several factors need to be considered when designing a MAS model; including contextualisation of MAS to the market. Stakeholder engagement, service planning, governance, implementation and review have emerged as key aspects involved with a design model. CONCLUSION: MASs differ in their structural parameters. Consideration of these parameters is necessary when devising MAS aims and assessing outcomes to promote sustainability and success of the service. PMID- 29444753 TI - Liposome mediated double-stranded RNA delivery to silence ribosomal protein P0 in the tick Rhipicephalus haemaphysaloides. AB - Control of ticks has been achieved primarily by the application of acaricides, which has drawbacks such as environmental contamination leading to the selection of pesticide-resistant ticks. The potential of dsRNA to suppress genes critical for tick survival due to its sequence specificity suggests that dsRNAs could be developed as tailor-made pesticides. In this study, the dsRNA of P0 gene from the tick, Rhipicephalus haemaphysaloides, was evaluated as a potential anti-tick agent. Effects of using different dsRNA delivery methods were tested by quantitative RT-PCR and tick bioassays to determine survival, feeding and reproduction. The results showed that P0 dsRNAs could be effectively delivered into ticks and silenced by incubating with liposomes. Incubation time was found to be the most important factor in dsRNA delivery and gene silencing compared with liposome types and dsRNA concentration. The effects of P0 dsRNA treatment on ticks were found to be significant on blood feeding, molting or reproduction. These data show that anti-tick agents based on dsRNAs could have potential use in tick control. PMID- 29444754 TI - Clinical rating systems in elbow research-a systematic review exploring trends and distributions of use. AB - BACKGROUND: Clinical rating systems are used as outcome measures in clinical trials and attempt to gauge the patient's view of his or her own health. The choice of clinical rating system should be supported by its performance against established quality standards. METHODS: A search strategy was developed to identify all studies that reported the use of clinical rating systems in the elbow literature. The strategy was run from inception in Medline Embase and CINHAL. Data extraction identified the date of publication, country of data collection, pathology assessed, and the outcome measure used. RESULTS: We identified 980 studies that reported clinical rating system use. Seventy-two separate rating systems were identified. Forty-one percent of studies used >=2 separate measures. Overall, 54% of studies used the Mayo Elbow Performance Score (MEPS). For arthroplasty, 82% used MEPS, 17% used Disabilities of Arm, Shoulder and Hand (DASH), and 7% used QuickDASH. For trauma, 66.7% used MEPS, 32% used DASH, and 23% used the Morrey Score. For tendinopathy, 31% used DASH, 23% used Patient-Rated Tennis Elbow Evaluation (PRTEE), and 13% used MEPS. Over time, there was an increased proportional use of the MEPS, DASH, QuickDASH, PRTEE, and the Oxford Elbow Score. CONCLUSIONS: This study identified a wide choice and usage of clinical rating systems in the elbow literature. Numerous studies reported measures without a history of either a specific pathology or cross cultural validation. Interpretability and comparison of outcomes is dependent on the unification of outcome measure choice. This was not demonstrated currently.

AB - Anaerobic digestion (AD) has been widely used for biogas or biofuel generation from waste treatment. Because a low production rate and instability of AD occur frequently, various technologies have been applied to improvement of AD. Microbial electrolysis cells (MECs), an emerging technology, can convert organic matter into hydrogen, methane, and other value-added products. Recent studies showed that application of MEC to AD (MEC-AD) can accelerate degradation of a substrate (including recalcitrant compounds) and alter AD microbial community by enriching exoelectrogens and methanogens thus increasing biogas production. With stable microbial communities established, improvement of MEC-AD for methane production was achieved. MEC-AD process can be monitored in real-time by detecting electric signals, which linearly correlate with substrate concentrations. This review attempts to evaluate interactions among the decomposition of substrates, MEC-AD system, and the microbial community. This analysis should provide useful insights into the improvement of methane production and the performance of MEC-AD. PMID- 29444758 TI - Electron transfer process in microbial electrochemical technologies: The role of cell-surface exposed conductive proteins. AB - Electroactive microorganisms have attracted significant interest for the development of novel biotechnological systems of low ecological footprint. These can be used for the sustainable production of energy, bioremediation of metal contaminated environments and production of added-value products. Currently, almost 100 microorganisms from the Bacterial and Archaeal domains are considered electroactive, given their ability to efficiently interact with electrodes in microbial electrochemical technologies. Cell-surface exposed conductive proteins are key players in the electron transfer between cells and electrodes. Interestingly, it seems that among the electroactive organisms identified so far, these cell-surface proteins fall into one of four groups. In this review, the different types of cell-surface conductive proteins found in electroactive organisms will be overviewed, focusing on their structural and functional properties. PMID- 29444759 TI - Current management of pelvic organ prolapse in aging women: EMAS clinical guide. AB - Management of pelvic organ prolapse (POP) is a common and challenging task. Nowadays older women are more active than they were in the past, and the development of POP disrupts quality of life and impairs social and personal activities. The menopausal transition is a time of vulnerability, during which many women start experiencing symptoms and signs of POP. The role of hormonal changes or of hormonal therapies in influencing the development or progression of POP has been explored extensively. The management of POP requires considerable clinical skills. Correct diagnosis and characterization of the prolapse and an identification of the individual woman's most bothersome symptoms are the hallmark of appropriate initial management. Therapy is multimodal and often multidisciplinary, and requires a competence in pelvic medicine and surgery. The integration of hormonal, non-hormonal and surgical strategies is important and needs to be adjusted to changing circumstances on an individualized basis. When surgery is required, optimal management requires clinicians who are familiar with the advantages and disadvantages of all the available strategies and who are able to use these strategies in a tailored manner. Complex cases should be sent to specialist referral centers. Management of POP should be integrated into the practice of healthcare professionals dealing in menopause. PMID- 29444760 TI - Risk factors for persistent Aspergillus respiratory isolation in cystic fibrosis. AB - BACKGROUND: Aspergillus species are increasingly detected in the respiratory tracts of individuals with cystic fibrosis (CF), and chronic Aspergillus fumigatus is associated with more frequent hospitalizations for pulmonary exacerbations. However, patient and clinical factors that may contribute to the acquisition of persistent Aspergillus infection have yet to be identified. The objective of this study was to identify risk factors for development of Aspergillus respiratory isolation in CF. METHODS: A retrospective cohort study of participants in the CF Foundation Patient Registry between 2006 and 2012 was conducted. Generalized estimating equation models were used to evaluate the association between the development of persistent Aspergillus respiratory isolation and individual level demographic and clinical characteristics. RESULTS: Among 16,095 individuals with CF followed from 2006 to 2012, 1541 (9.6%) subjects developed persistent Aspergillus isolation. White race (Odds Ratio [OR] 1.74, 95% confidence interval 1.23, 2.48, p<0.001) and pancreatic insufficiency (OR 1.50, 95% CI 1.09, 2.06, p<0.001) were found to be risk factors for persistent Aspergillus isolation. Chronic therapies, including inhaled antibiotics (OR 1.33; 95% CI 1.21, 1.46), macrolides (OR 1.23, 95% CI 1.14, 1.32, p<0.001), and inhaled corticosteroids (OR 1.13, 95% CI 1.04, 1.20, p<0.001) were also independently associated with an increased risk for persistent Aspergillus isolation. CONCLUSIONS: We identified macrolides and inhaled antibiotics, which individually have been shown to improve CF outcomes, and inhaled corticosteroids as risk factors for developing persistent Aspergillus isolation. Further work is needed to determine whether these associations are causal or due to confounding by other factors. PMID- 29444761 TI - Chronic infection sustained by a Pseudomonas aeruginosa High-Risk clone producing the VIM-1 metallo-beta-lactamase in a cystic fibrosis patient after lung transplantation. AB - BACKGROUND: The significance of chronic lung infection by multidrug-resistant (MDR) pathogens in Cystic Fibrosis (CF) transplanted patients remains controversial, and the available information is overall limited. Here we describe the case of a chronic infection, sustained by a metallo-beta-lactamase (MBL) producing P. aeruginosa strain, in a CF patient following lung transplantation. METHODS: Twelve P. aeruginosa isolates collected from a CF patient over a 15 years follow-up period after lung transplantation were analysed for their antibiotic susceptibility profile, MBL production and clonal relatedness. Available clinical and microbiological records were reviewed. RESULTS: The transplanted CF patient was chronically infected by an MBL-producing P. aeruginosa strain which harboured a blaVIM-1 determinant inserted into a novel class 1 integron. The strain exhibited an MDR phenotype and belonged to the globally widespread ST235 epidemic clonal lineage, which however is not a typical CF-associated epidemic clone. Despite the chronic infection, the long-term outcome of this patient during the post-transplant period was characterized by the absence of acute exacerbations and by a mostly stable pulmonary function. CONCLUSIONS: This report provides one of the few descriptions of MBL-producing P. aeruginosa infections in CF patients, and the first description of such an infection after lung transplantation in these patients. Infection with the MBL producing strain apparently did not significantly affect the patient pulmonary function. PMID- 29444762 TI - Hemimegalencephaly with Bannayan-Riley-Ruvalcaba syndrome. AB - Hemimegalencephaly is known to occur in Proteus syndrome, but has not been reported, to our knowledge, in the other PTEN mutation-related syndrome of Bannayan-Riley-Ruvalcaba. Here, we report a patient with Bannayan-Riley-Ruvalcaba syndrome who also had hemimegalencephaly and in whom the hemimegalencephaly was evident well before presentation of the characteristic manifestations of Bannayan Riley-Ruvalcaba syndrome. An 11-year-old boy developed drug-resistant focal seizures on the fifth day of life. MRI revealed left hemimegalencephaly. He later showed macrocephaly, developmental delay, athetotic quadriplegic cerebral palsy, and neuromuscular scoliosis. Freckling of the penis, which is characteristic of Bannayan-Riley-Ruvalcaba syndrome, was not present at birth but was observed at 9 years of age. Gene analysis revealed a c.510 T>G PTEN mutation. This patient and his other affected family members, his father and two siblings, were started on the tumour screening procedures recommended for patients with PTEN mutations. This case highlights the importance of early screening for PTEN mutations in cases of hemimegalencephaly not otherwise explained by another disorder, even in the absence of signs of Proteus syndrome or the full manifestations of Bannayan Riley Ruvalcaba syndrome.

AB - Somatosensory reflex epilepsy is induced by repetitive cutaneous contact of a circumscribed body area with a tight time-lock between somatosensory stimulation and seizure. We describe the case of a 27-year-old man with seizures induced by repetitive tapping on the sole of the right foot. Simultaneous video-EEG monitoring and surface electromyography was performed during a seizure triggered by repetitive tapping on the right sole aspect using a hammer. Stimulation produced a tingling sensation on the right sole that extended to the right lower leg. This was followed by motor Jacksonian march of the right leg.

PMID- 29444764 TI - Clinical-radiological-pathological correlation in an unusual case of refractory epilepsy: a two-year journey of whodunit! AB - New-onset refractory focal epilepsy poses significant challenges to the clinician in the absence of specific diagnostic biomarkers. Differential diagnoses based on imaging may be expanded by a veritable spectrum of peri-ictal imaging findings that may mask the underlying substrate. We report a 13-year-old girl who presented with refractory focal seizures of left parieto-occipital origin with cytotoxic gyral oedema noted over the same region on imaging. Despite an initial negative autoantibody profile, the patient was treated with immunosuppression, followed by serial relapses requiring immune-modulation. Over the next year, her syndrome persisted as focal left posterior cortex epilepsy that necessitated occipital lobectomy, following a relapsing-remitting radiological profile, consistent with peri-ictal MRI changes. Histopathology was inconclusive for any definitive substrate. After a period of quiescence, she developed focal motor seizures of right hemispheric origin with progressive encephalopathy, at which point a repeat cerebrospinal fluid anti-N-methyl-D-aspartate receptor antibody profile returned positive. The patient was managed with steroids and rituximab with a good clinical outcome. We hypothesise that persistent or relapsing remitting focal gyral oedema in unexplained refractory focal epilepsy mandates consideration of focal encephalitis secondary to autoimmunity, and late appearance of intrathecal auto-antibody synthesis correlates with evolution into a more diffuse disease. PMID- 29444765 TI - Early infancy-onset stimulation-induced myoclonic seizures in three siblings with inherited glycosylphosphatidylinositol (GPI) anchor deficiency. AB - Inherited glycosylphosphatidylinositol anchor deficiency causes a variety of clinical symptoms, including epilepsy, however, little information is available regarding seizures as a symptom. We report three siblings with inherited glycosylphosphatidylinositol anchor deficiency with PIGL gene mutations. The phenotypes of the subjects were not consistent with CHIME syndrome or Mabry syndrome, as reported in previous studies. All shared some clinical manifestations, including transient apnoea as neonates, dysmorphic facial features, and intellectual disability. Between one week and 3 months of life, all patients developed myoclonic seizures. Myoclonic jerks were easily evoked by sudden unexpected acoustic or tactile stimuli. None showed elevation of serum alkaline phosphatase. Vitamin B6 was given to one of the three siblings, but failed to suppress seizures. The presence of early infancy-onset stimulation induced myoclonic seizures combined with dysmorphic facial features should lead physicians to consider the possibility of inherited glycosylphosphatidylinositol anchor deficiency.

PMID- 29444767 TI - Patient-Reported Measures for Person-Centered Coordinated Care: A Comparative Domain Map and Web-Based Compendium for Supporting Policy Development and Implementation. AB - BACKGROUND: Patient-reported measure (PRM) questionnaires were originally used in research to measure outcomes of intervention studies. They have now evolved into a diverse family of tools measuring a range of constructs including quality of life and experiences of care. Current health and social care policy increasingly advocates their use for embedding the patient voice into service redesign through new models of care such as person-centered coordinated care (P3C). If chosen carefully and used efficiently, these tools can help improve care delivery through a variety of novel ways, including system-level feedback for health care management and commissioning. Support and guidance on how to use these tools would be critical to achieve these goals. OBJECTIVE: The objective of this study was to develop evidence-based guidance and support for the use of P3C-PRMs in health and social care policy through identification of PRMs that can be used to enhance the development of P3C, mapping P3C-PRMs against an existing model of domains of P3C, and integration and organization of the information in a user friendly Web-based database. METHODS: A pragmatic approach was used for the systematic identification of candidate P3C-PRMs, which aimed at balancing comprehensiveness and feasibility. This utilized a number of resources, including existing compendiums, peer-reviewed and gray literature (using a flexible search strategy), and stakeholder engagement (which included guidance for relevant clinical areas). A subset of those candidate measures (meeting prespecified eligibility criteria) was then mapped against a theoretical model of P3C, facilitating classification of the construct being measured and the subsequent generation of shortlists for generic P3C measures, specific aspects of P3C (eg, communication or decision making), and condition-specific measures (eg, diabetes, cancer) in priority areas, as highlighted by stakeholders. RESULTS: In total, 328 P3C-PRMs were identified, which were used to populate a freely available Web based database. Of these, 63 P3C-PRMs met the eligibility criteria for shortlisting and were classified according to their measurement constructs and mapped against the theoretical P3C model. We identified tools with the best coverage of P3C, thereby providing evidence of their content validity as outcome measures for new models of care. Transitions and medications were 2 areas currently poorly covered by existing measures. All the information is currently available at a user-friendly web-based portal (p3c.org.uk), which includes all relevant information on each measure, such as the constructs targeted and links to relevant literature, in addition to shortlists according to relevant constructs. CONCLUSIONS: A detailed compendium of P3C-PRMs has been developed using a pragmatic systematic approach supported by stakeholder engagement. Our user-friendly suite of tools is designed to act as a portal to the world of PRMs for P3C, and have utility for a broad audience, including (but not limited to) health care commissioners, managers, and researchers. PMID- 29444768 TI - Web-Based Just-in-Time Information and Feedback on Antibiotic Use for Village Doctors in Rural Anhui, China: Randomized Controlled Trial. AB - BACKGROUND: Excessive use of antibiotics is very common worldwide, especially in rural China; various measures that have been used in curbing the problem have shown only marginal effects. OBJECTIVE: The objective of this study was to test an innovative intervention that provided just-in-time information and feedback (JITIF) to village doctors on care of common infectious diseases. METHODS: The information component of JITIF consisted of a set of theory or evidence-based ingredients, including operation guideline, public commitment, and takeaway information, whereas the feedback component tells each participating doctor about his or her performance scores and percentages of antibiotic prescriptions. These ingredients were incorporated together in a synergetic way via a Web-based aid. Evaluation of JITIF adopted a randomized controlled trial design involving 24 village clinics randomized into equal control and intervention arms. Measures used included changes between baseline and endpoint (1 year after baseline) in terms of: percentages of patients with symptomatic respiratory or gastrointestinal tract infections (RTIs or GTIs) being prescribed antibiotics, delivery of essential service procedures, and patients' beliefs and knowledge about antibiotics and infection prevention. Two researchers worked as a group in collecting the data at each site clinic. One performed nonparticipative observation of the service process, while the other performed structured exit interviews about patients' beliefs and knowledge. Data analysis comprised mainly of: (1) descriptive estimations of beliefs or knowledge, practice of indicative procedures, and use of antibiotics at baseline and endpoint for intervention and control groups and (2) chi-square tests for the differences between these groups. RESULTS: A total of 1048 patients completed the evaluation, including 532 at baseline (intervention=269, control=263) and 516 at endpoint (intervention=262, control=254). Patients diagnosed with RTIs and GTIs accounted for 76.5% (407/532) and 23.5% (125/352), respectively, at baseline and 80.8% (417/532) and 19.2% (99/532) at endpoint. JITIF resulted in substantial improvement in delivery of essential service procedures (2.6%-24.8% at baseline on both arms and at endpoint on the control arm vs 88.5%-95.0% at endpoint on the intervention arm, P<.001), beliefs favoring rational antibiotics use (11.5%-39.8% at baseline on both arms and at endpoint on the control arm vs 19.8%-62.6% at endpoint on the intervention arm, P<.001) and knowledge about side effects of antibiotics (35.7% on the control arm vs 73.7% on the intervention arm, P<.001), measures for managing or preventing RTIs (39.1% vs 66.7%, P=.02), and measures for managing or preventing GTIs (46.8% vs 69.2%, P<.001). It also reduced antibiotics prescription (from 88.8%-62.3%, P<.001), and this decrease was consistent for RTIs (87.1% vs 64.3%, P<.001) and GTIs (94.7% vs 52.4%, P<.001). CONCLUSIONS: JITIF is effective in controlling antibiotics prescription at least in the short term and may provide a low-cost and sustainable solution to the widespread excessive use of antibiotics in rural China. PMID- 29444769 TI - Effectiveness of a Web-Based Self-Help Program for Suicidal Thinking in an Australian Community Sample: Randomized Controlled Trial. AB - BACKGROUND: Treatment for suicidality can be delivered online, but evidence for its effectiveness is needed. OBJECTIVE: The goal of our study was to examine the effectiveness of an online self-help intervention for suicidal thinking compared to an attention-matched control program. METHODS: A 2-arm randomized controlled trial was conducted with assessment at postintervention, 6, and, 12 months. Through media and community advertizing, 418 suicidal adults were recruited to an online portal and were delivered the intervention program (Living with Deadly Thoughts) or a control program (Living Well). The primary outcome was severity of suicidal thinking, assessed using the Columbia Suicide Severity Rating Scale. RESULTS: Intention-to-treat analyses showed significant reductions in the severity of suicidal thinking at postintervention, 6, and 12 months. However, no overall group differences were found. CONCLUSIONS: Living with Deadly Thoughts was of no greater effectiveness than the control group. Further investigation into the conditions under which this program may be beneficial is now needed. Limitations of this trial include it being underpowered given the effect size ultimately observed, a high attrition rate, and the inability of determining suicide deaths or of verifying self-reported suicide attempts.

PMID- 29444771 TI - Consumption of ultra-processed foods and cancer risk: results from NutriNet-Sante prospective cohort. AB - OBJECTIVE: To assess the prospective associations between consumption of ultra processed food and risk of cancer. DESIGN: Population based cohort study. SETTING AND PARTICIPANTS: 104 980 participants aged at least 18 years (median age 42.8 years) from the French NutriNet-Sante cohort (2009-17). Dietary intakes were collected using repeated 24 hour dietary records, designed to register participants' usual consumption for 3300 different food items. These were categorised according to their degree of processing by the NOVA classification. MAIN OUTCOME MEASURES: Associations between ultra-processed food intake and risk of overall, breast, prostate, and colorectal cancer assessed by multivariable Cox proportional hazard models adjusted for known risk factors. RESULTS: Ultra processed food intake was associated with higher overall cancer risk (n=2228 cases; hazard ratio for a 10% increment in the proportion of ultra-processed food in the diet 1.12 (95% confidence interval 1.06 to 1.18); P for trend<0.001) and breast cancer risk (n=739 cases; hazard ratio 1.11 (1.02 to 1.22); P for trend=0.02). These results remained statistically significant after adjustment for several markers of the nutritional quality of the diet (lipid, sodium, and carbohydrate intakes and/or a Western pattern derived by principal component analysis). CONCLUSIONS: In this large prospective study, a 10% increase in the proportion of ultra-processed foods in the diet was associated with a significant increase of greater than 10% in risks of overall and breast cancer. Further studies are needed to better understand the relative effect of the various dimensions of processing (nutritional composition, food additives, contact materials, and neoformed contaminants) in these associations. STUDY REGISTRATION: Clinicaltrials.gov NCT03335644. PMID- 29444773 TI - Lung Function, Inflammation, and Endothelin-1 in Congenital Heart Disease Associated Pulmonary Arterial Hypertension. AB - BACKGROUND: Breathlessness is the most common symptom in people with pulmonary arterial hypertension and congenital heart disease (CHD-APAH), previously thought to be caused by worsening PAH, but perhaps also by inflammation and abnormalities of lung function. We studied lung function and airway inflammation in patients with CHD-APAH and compared the results with controls. METHODS AND RESULTS: Sixty people were recruited into the study: 20 CHD-APAH, 20 CHD controls, and 20 healthy controls. Spirometry, gas transfer, whole body plethysmography and lung clearance index, 6-minute walk distance, and medical research council dyspnea scoring were performed. Inflammatory markers and endothelin-1 levels were determined in blood and induced sputum. The CHD-APAH group had abnormal lung function with lung restriction, airway obstruction, and ventilation heterogeneity. Inverse correlations were shown for CHD-APAH between medical research council dyspnea score and percent predicted peak expiratory flow (r= 0.5383, P=0.0174), percent predicted forced expiratory flow rate at 50% of forced vital capacity (r=-0.5316, P=0.0192), as well as for percent predicted forced expiratory volume in 1 s (r=-0.6662, P=0.0018) and percent predicted forced vital capacity (r=-0.5536, P=0.0186). The CHD-APAH patients were more breathless with lower 6-minute walk distance (360 m versus 558 m versus 622 m, P=0.00001). Endothelin-1, interleukin (IL)-beta, IL-6, IL-8, tumor necrosis factor alpha, and vascular endothelial growth factor were significantly higher in CHD-APAH than controls. Serum endothelin-1 for CHD-APAH correlated with airflow obstruction with significant negative correlations with percent predicted forced expiratory flow rate at 75% of forced vital capacity (r=-0.5858, P=0.0135). CONCLUSIONS: Raised biomarkers for inflammation were found in CHD-APAH. Significant abnormalities in airway physiology may contribute to the dyspnea but are not driven by inflammation as assessed by circulating and sputum cytokines. A relationship between increased serum endothelin-1 and airway dysfunction may relate to its bronchoconstrictive properties. PMID- 29444775 TI - Persistent inequalities in Hospice at Home provision. AB - OBJECTIVE: To describe the nature and scope of a new Hospice at Home (H@H) service and to identify its equality of provision. METHODS: Case note review of patients supported by a H@H service for 1 year from September 2012 to August 2013 (n=321). Descriptive analysis to report frequencies and proportions of quantitative data extracted from service logs, referral forms and care records; thematic analysis of qualitative data from care record free text. RESULTS: Demand outstripped supply. Twice as many night care episodes were requested (n=1237) as were provided (n=613). Inequalities in access to the service related to underlying diagnosis and socioeconomic status. 75% of patients using the service had cancer (221/293 with documented diagnosis). Of those who died at home in the areas surrounding the hospice, 53% (163/311) of people with cancer and 11% (49/431) of those without cancer received H@H support. People who received H@H care were often more affluent than the population average for the area within which they lived. Roles of the service identified included: care planning/implementation, specialist end-of-life care assessment and advice, 'holding' complex patients until hospice beds become available and clinical nursing care. CONCLUSION: There is significant unmet need and potentially large latent demand for the H@H service. People without cancer or of lower socioeconomic status are less likely to access the service. Action is needed to ensure greater and more equitable service provision in this and similar services nationally and internationally. PMID- 29444774 TI - Comparison Between Different Strategies of Rheumatic Heart Disease Echocardiographic Screening in Brazil: Data From the PROVAR (Rheumatic Valve Disease Screening Program) Study. AB - BACKGROUND: Considering the limited accuracy of clinical examination for early diagnosis of rheumatic heart disease (RHD), echocardiography has emerged as an important epidemiological tool. The ideal setting for screening is yet to be defined. We aimed to evaluate the prevalence and pattern of latent RHD in schoolchildren (aged 5-18 years) and to compare effectiveness of screening between public schools, private schools, and primary care centers in Minas Gerais, Brazil. METHODS AND RESULTS: The PROVAR (Rheumatic Valve Disease Screening Program) study uses nonexperts and portable and handheld devices for RHD echocardiographic screening, with remote interpretation by telemedicine, according to the 2012 World Heart Federation criteria. Compliance with study consent and prevalence were compared between different screening settings, and variables associated with RHD were analyzed. In 26 months, 12 048 students were screened in 52 public schools (n=10 901), 2 private schools (n=589), and 3 primary care centers (n=558). Median age was 12.9 years, and 55.4% were girls. Overall RHD prevalence was 4.0% borderline (n=486) and 0.5% definite (n=63), with statistically similar rates between public schools (4.6%), private schools (3.5%), and primary care centers (4.8%) (P=0.24). The percentage of informed consents signed was higher in primary care centers (84.4%) and private schools (66.9%) compared with public schools (38.7%) (P<0.001). Prevalence was higher in children >=12 years (5.3% versus 3.1%; P<0.001) and girls (4.9% versus 4.0%; P=0.02). Only age (odds ratio, 1.12; 95% confidence interval, 1.09-1.17; P<0.001) was independently associated with RHD. CONCLUSIONS: RHD screening in primary care centers seems to achieve higher coverage rates. Prevalence among schoolchildren is significantly high, with rates higher than expected in private schools of high income areas. These data are important for the formulation of public policies to confront RHD. PMID- 29444776 TI - Association between spectral characteristics of paraspinal muscles and functional disability in patients with low back pain: a cohort study. AB - OBJECTIVES: Characteristics of muscle activity, represented by surface electromyography (EMG), have revealed differences between patients with low back pain (LBP) and healthy adults; how they relate to functional and clinical parameters remains unclear. The purpose of the current study was to examine the correlation between frequency characteristics of EMG (analysed using continuous wavelet transform (CWT) analysis) and patients' self-rated score of disability. DESIGN AND SETTING: This is a case-control study with 15 patients with mechanical LBP without radicular symptoms. Patients were recruited from the orthopaedic clinic at Charing Cross Hospital. Ten healthy adults were recruited from the staff working in the hospital and associated university. Patients completed the Roland-Morris Disability Questionnaire (RMDQ) and bilateral EMG activity was obtained from erector spinae at vertebral levels L4 and T12. Subjects performed three brief maximal voluntary isometric contractions (MVICs) of the back extensors and the torque was measured using a dynamometer. CWT was applied to the EMG signals of each muscle in a 200 ms window centred around the peak torque obtained during the MVICs. The ratio (low/high frequencies) of the energy, the peak power and the frequency of the peak power were calculated for each recording site, averaged and correlated with the individual's RMDQ score. RESULTS: Patients had lower peak power (T12 and L4) and lower frequency of the peak power (at T12) than the healthy adults. Additionally, RMDQ positively correlated to the average ratio of energy at T12 (r=0.63; p=0.012), that is, greater self-rated disability corresponded to a dominant distribution of energy in the lower frequencies. CONCLUSION: The current findings reveal alterations in EMG profile and its association with self-related back pain disability, suggesting that spectral characteristics of EMG reflect muscle function. PMID- 29444777 TI - Estimates of prevalence, demographic characteristics and social factors among people with disabilities in the USA: a cross-survey comparison. AB - OBJECTIVE: A national priority for disability research in the USA is the standardised identification of people with disabilities in surveillance efforts. Mandated by federal statute, six dichotomous difficulty-focused questions were implemented in national surveys to identify people with disabilities. The aim of this study was to assess the prevalence, demographic characteristics and social factors among people with disabilities based on these six questions using multiple national surveys in the USA. SETTING: American Community Survey (ACS), Current Population Survey Annual Social and Economic Supplement (CPS-ASEC), National Health Interview Survey (NHIS) and the Survey of Income and Program Participation (SIPP). PARTICIPANTS: Civilian, non-institutionalised US residents aged 18 and over from the 2009 to 2014 ACS, 2009 to 2014 CPS-ASEC, 2009 to 2014 NHIS and 2008 SIPP waves 3, 7 and 10. PRIMARY AND SECONDARY OUTCOME MEASURES: Disability was assessed using six standardised questions asking people about hearing, vision, cognition, ambulatory, self-care and independent living disabilities. Social factors were assessed with questions asking people to report their education, employment status, family size, health and marital status, health insurance and income. RESULTS: Risk ratios and demographic distributions for people with disabilities were consistent across survey. People with disabilities were at decreased risk of having college education, employment, families with three or more people, excellent or very good self-reported health and a spouse. People with disabilities were also consistently at greater risk of having health insurance and living below the poverty line. Estimates of disability prevalence varied between surveys from 2009 to 2014 (range 11.76% 17.08%). CONCLUSION: Replicating the existing literature, we found the estimation of disparities and inequity people with disabilities experience to be consistent across survey. Although there was a range of prevalence estimates, demographic factors for people with disabilities were consistent across surveys. Variations in prevalence estimates can be explained by survey context effects. PMID- 29444778 TI - Efficacy and safety of the Shexiang Baoxin Pill for the treatment of coronary artery disease not amenable to revascularisation: study protocol for a randomised, placebo-controlled, double-blinded trial. AB - INTRODUCTION: Coronary artery disease (CAD) not amenable to revascularisation indicates that the coronary arteries have severe diffuse lesions or calcifications, or that CAD is complicated with severe multiple-organ disease. Currently, Western medicines available for the treatment of CAD not amenable to revascularisation are limited. Shexiang Baoxin Pill (SBP), a type of Chinese patent medicine, has been widely used to treat CAD in China for many years. Previous studies have shown that long-term administration of SBP (1-2 pills three times daily, for at least 6 months) for treatment of CAD is effective and safe, with a significant, long-term effect. This study aims to evaluate the efficacy and safety of SBP in patients with CAD not amenable to revascularisation. METHODS AND ANALYSIS: This is a multicentre, randomised, double-blinded, placebo controlled clinical trial. A total of 440 participants will be randomly allocated to two groups: the intervention group and the placebo group. Based on conventional treatment with Western medicine, the intervention group will be treated with SBP and the placebo group will be treated with SBP placebo. The primary outcomes include major adverse cardiovascular events (including angina, acute myocardial infarction, pulmonary embolism and aortic dissection). The secondary outcomes include C reactive protein, B-type natriuretic peptide, ECG, echocardiographic parameters (ejection fraction percentage and the E/A ratio) and hospital readmission rates due to CAD. Assessments will be performed at baseline (before randomisation) and at 24 weeks after randomisation. ETHICS AND DISSEMINATION: The protocol has been approved by the Research Ethics Committee of Guang'anmen Hospital, China Academy of Chinese Medical Sciences in Beijing, China (reference: 2016-129-KY-01). The results of this study will be published in a peer-reviewed journal and will be used as a basis for a multisite trial. TRIAL REGISTRATION NUMBER: NCT03072121; Pre-results. PMID- 29444779 TI - Estimating the met need for emergency obstetric care (EmOC) services in three payams of Torit County, South Sudan: a facility-based, retrospective cross sectional study. AB - OBJECTIVE: To determine the met need for emergency obstetric care (EmOC) services in three Payams of Torit County, South Sudan in 2015 and to determine the frequency of each major obstetric complication. DESIGN: This was a retrospective cross-sectional study. SETTING: Four primary healthcare centres (PHCCs) and one state hospital in three payams (administrative areas that form a county) in Torit County, South Sudan. PARTICIPANTS: All admissions in the obstetrics and gynaecology wards (a total of 2466 patient admission files) in 2015 in all the facilities designated to conduct deliveries in the study area were reviewed to identify obstetric complications. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was met need for EmOC, which was defined as the proportion of all women with direct major obstetric complications in 2015 treated in health facilities providing EmOC services. The frequency of each complication and the interventions for treatment were the secondary outcomes. RESULTS: Two hundred and fifty four major obstetric complications were admitted in 2015 out of 390 expected from 2602 pregnancies, representing 65.13% met need. The met need was highest (88%) for Nyong Payam, an urban area, compared with the other two rural payams, and 98.8% of the complications were treated from the hospital, while no complications were treated from three PHCCs. The most common obstetric complications were abortions (45.7%), prolonged obstructed labour (23.2%) and haemorrhage (16.5%). Evacuation of the uterus for retained products (42.5%), caesarean sections (32.7%) and administration of oxytocin for treatment of postpartum haemorrhage (13.3%) were the most common interventions. CONCLUSION: The met need for EmOC in Torit County is low, with 35% of women with major obstetric complications not accessing care, and there is disparity with Nyong Payam having a higher met need. We suggest more support supervision to the PHCCs to increase access for the rural population. PMID- 29444781 TI - Do quality improvement initiatives for diabetes care address social inequities? Secondary analysis of a systematic review. AB - BACKGROUND: Socially disadvantaged populations carry a disproportionate burden of diabetes-related morbidity and mortality. There is an emerging interest in quality improvement (QI) strategies in the care of patients with diabetes, however, the effect of these interventions on disadvantaged groups remains unclear. OBJECTIVE: This is a secondary analysis of a systematic review that seeks to examine the extent of equity considerations in diabetes QI studies, specifically quantifying the proportion of studies that target interventions toward disadvantaged populations and conduct analyses on the impact of interventions on disadvantaged groups. RESEARCH DESIGN AND METHODS: Studies were identified using Medline, HealthStar and the Cochrane Effective Practice and Organisation of Care database. Randomised controlled trials assessing 12 QI strategies targeting health systems, healthcare professionals and/or patients for the management of adult outpatients with diabetes were eligible. The place of residence, race/ethnicity/culture/language, occupational status, gender/sexual identity, religious affiliations, education level, socioeconomic status, social capital, plus age, disability, sexual preferences and relationships (PROGRESS Plus) framework was used to identify trials that focused on disadvantaged patient populations, to examine the types of equity-relevant factors that are being considered and to explore temporal trends in equity-relevant diabetes QI trials. RESULTS: Of the 278 trials that met the inclusion criteria, 95 trials had equity relevant considerations. These include 64 targeted trials that focused on a disadvantaged population with the aim to improve the health status of that population and 31 general trials that undertook subgroup analyses to assess the extent to which their interventions may have had differential impacts on disadvantaged subgroups. Trials predominantly focused on race/ethnicity, socioeconomic status and place of residence as potential factors for disadvantage in patients receiving diabetes care. CONCLUSIONS: Less than one-third of diabetes QI trials included equity-relevant considerations, limiting the relevance and applicability of their data to disadvantaged populations. There is a need for better data collection, reporting, analysis and interventions on the social determinants of health that may influence the health outcomes of patients with diabetes.

AB - BACKGROUND: Kawasaki disease (KD) is a self-limited acute systemic vasculitis of unknown aetiology that predominantly affects infants and young children eventually associated with immunological abnormalities. Coeliac disease (CD) is an inflammatory autoimmune disease characterised by a permanent gluten intolerance, which affects genetically susceptible individuals of any age group, and can cause intestinal and systemic symptoms. Association of CD with KD has been previously described in a single study that disclosed a surprisingly high prevalence of CD in children with a history of KD. OBJECTIVE: To confirm the existence of a higher prevalence of CD among individuals with a history of KD, which would turn the screening for CD in patients with history of KD highly advisable. SETTING: Children with history of KD, diagnosed and followed at the Rheumatology Clinic of the Children's Hospital of Brasilia (Brasilia, Brazil). PARTICIPANTS: This study included 110 children with history of KD and a control group composed of 110 presumably healthy children. INTERVENTIONS: Participants underwent anti-transglutaminase and anti-endomysial antibodies tests and genetic typing for the presence of CD predisposing alleles (HLA-DQ2 and DQ8). Jejunal biopsy was performed when necessary, according the European Society of Paediatric Gastroenterology, Hepatology and Nutrition guidelines. RESULTS: Diagnosis of CD was confirmed in one (0.91%) patient with KD by positive serological tests, presence of predisposing alleles and CD typical lesions on duodenal biopsy. All serological tests were negative among the controls. The prevalence of CD predisposing alleles among patients with KD was 29.09%, similar to the prevalence found among controls, 33.64%. CONCLUSION: The detected CD prevalence (0.91%) does not confirm the existence of an association between KD and CD since this prevalence is similar to that found in the general population (?1%).

AB - INTRODUCTION: Attracting graduates was recommended as a means of diversifying the UK medical student population. Graduates now make up nearly a quarter of the total medical student population. Research to date has focused on comparing the sociodemographic characteristics of applicants to and/or students on traditional and graduate entry programmes (GEMs), yet GEMs account for only 40% of the graduate medical student population. Thus, we aimed to compare the sociodemographic characteristic and outcomes of graduates and non-graduate applicants across a range of programmes. METHODS: This was an observational study of 117 214 applicants to medicine who took the UK Clinical Aptitude Test (UKCAT) from 2006 to 2014 and who applied to medical school through Universities and Colleges Admissions Service (UCAS). We included applicant demographics, UKCAT total score and offers in our analysis. Applicants were assigned as graduates or non-graduates on the basis of their highest qualification. Multiple logistic regression was used to predict the odds of receiving an offer, after adjusting for confounders. RESULTS: Irrespective of graduate or non-graduate status, most applicants were from the highest socioeconomic groups and were from a white ethnic background. Receiving an offer was related to gender and ethnicity in both graduates and non-graduates. After adjusting for UKCAT score, the OR of an offer for graduates versus non-graduates was approximately 0.5 (OR=0.48, 95% CI 0.46 to 0.49). DISCUSSION: Our findings indicate that the aim of diversifying the medical student population on socioeconomic grounds by attracting graduates has been only marginally successful. Graduate applicants from widening access backgrounds are less likely than others to be offered a place at medical school. Different approaches must be considered if medicine is to attract and select more socially diverse applicants.

AB - OBJECTIVE: This investigation reports the cause and the quality of death certification in a community cohort of patients with Parkinson's disease (PD) and controls at 18 years. SETTING: Denbighshire North Wales, UK. PARTICIPANTS: The community-based cohorts consisted of 166 patients with PD and 102 matched controls. PRIMARY OUTCOMES: All-cause mortality was ascertained at 18 years by review of hospitals' primary care records and examination of death certificates obtained from the UK General Register Office. Mortality HRs were estimated using Cox proportional regression, controlling for covariates including age at study entry, age at death, gender, motor function, mood, health-related quality of life (HRQoL) and cognitive function. RESULTS: After 18 years, 158 (95%) of patients in the PD cohort and 34 (33%) in the control cohort had died. Compared with the general UK population, the PD cohort had a higher risk of mortality (standard mortality rate, 1.82, 95% CI 1.55 to 2.13). As the primary or underlying cause of death, PD was not reported in 75/158 (47%) of the death certificates. In addition, although 144/158 (91%) of the PD cohort had a diagnosis of dementia, this was reported in less than 10% of death certificates. The main cause of death reported in the PD cohort was pneumonia (53%), followed by cardiac-related deaths (21%). Compared with controls, patients with PD had a greater risk of pneumonia (2.03, 95% CI 1.34 to 3.6), poorer HRQoL and more likely to reside in institutional care at death (P<0.01). CONCLUSION: This investigation found that PD was associated with an excess risk of mortality compared with the general population. However, PD as a primary or underlying cause of death recorded on certificates was found to be suboptimal. This suggests that the quality of mortality statistics drawn from death certificates alone is not a valid or reliable source of data.

AB - INTRODUCTION: Obesity has become one of the biggest public health problems of the 21st century. Prevalence of obesity in children and adolescents has increased dramatically worldwide over the last 20 years, and this trend is expected to continue. Obesity in childhood is concerning as it predicts obesity in adulthood, a common risk factor for a wide array of chronic diseases and poor health outcomes. Obesity is preventable and a vast but fragmented body of evidence on preventative interventions is now available. This article outlines the protocol for a scoping review of published literature reviews on interventions to prevent obesity in children. The scoping review addresses the broad research question 'What is the evidence on interventions to prevent childhood obesity?'. It aims to give an overview of the various interventions available, understand those which are effective and identify barriers and facilitators to their effectiveness. METHODS AND ANALYSIS: The six-staged Arksey and O'Malley methodology framework is used to guide the scoping review process: following the definition of the research questions (stage 1); the eligibility criteria and search strategy are defined (stage 2); the study selection process based on the eligibility criteria identified will follow (stage 3); a framework developed for this review will then inform the extraction and charting of data from the included reviews (stage 4); results will be aggregated and summarised with criteria relevant for health professionals and policy-makers (stage 5); and the optional consultation (stage 6) exercise is not planned. ETHICS AND DISSEMINATION: Since the scoping review methodology aims at synthetising information from available publications, this study does not require ethical approval. An article reporting the results of the scoping review will be submitted for publication to a scientific journal, presented at relevant conferences and disseminated as part of future workshops with professionals involved in obesity prevention. PMID- 29444785 TI - Longitudinal changes in intraocular pressure and association with systemic factors and refractive error: Lingtou Eye Cohort Study. AB - OBJECTIVES: To investigate the longitudinal changes in intraocular pressure (IOP) and its associations with refractive error and systemic determinants in a Chinese geriatric population. DESIGN: Prospective cohort study. SETTING: Guangzhou Government Servant Physical Check-up Center, Guangzhou, China. PARTICIPANTS: 4413 government employees aged no less than 40 years (41.9% female) attending annual physical and eye examinations were included in this study. The inclusion criterion was having attended the 2010 follow-up examination. The exclusion criteria include glaucoma or intraocular surgery history, IOP >21 mm Hg at any visit or without available IOP data at all visits from 2010 to 2014. PRIMARY AND SECONDARY OUTCOME MEASURES: The outcome measure was IOP at each follow-up visit from 2010 to 2014. Mixed-effect model was used to assess the relationship between longitudinal changes in IOP and potential risk factors. RESULTS: For the 2653 participants who had available IOP data at both the 2010 and 2014 follow-up visits, the average change in IOP was an increase of 0.43 (95% CI 0.36 to 0.50) mm Hg. For the whole study population and in the optimised mixed model, there was a non-linear increase of IOP with age (P<0.001), with greater changes in younger subjects and in women (P<0.001 and P=0.002, respectively). Elevations in systolic blood pressure, diastolic blood pressure, body mass index (BMI) and fasting plasma glucose (FPG), as well as a myopic shift (all with P<0.001), during the follow-up were associated with an increasing trend of IOP, while serum lipids were found to be not significantly associated. CONCLUSIONS: In this cohort of elderly Chinese adults, IOP increases non-linearly with ageing. People with increasing blood pressure, BMI, FPG and myopic progression are more likely to have IOP elevation over time.

AB - INTRODUCTION: Rheumatic heart disease (RHD) remains an important cause of cardiovascular morbidity and mortality globally due to weak health systems in many countries. RHD can be effectively prevented and managed; however, RHD related interventions have not been widely adopted in countries with severe human resource constraints. Task sharing is a recognised approach to personnel shortages that could prove effective for RHD and has, anecdotally, been attempted in a few settings. We propose a systematic review and meta-analysis protocol to assess models that use non-physician workers to expand access to, and quality of, RHD-related healthcare. METHODS: We will include randomised controlled trials (RCT), cluster RCTs, quasi-experimental and controlled before and after studies providing information on the effectiveness of non-physician workers in providing care for streptoccocal pharyngitis, rheumatic fever and RHD. We will search relevant electronic databases and grey literature using medical subject headings. Standardised data extraction forms will be used to collect effect sizes that will be pooled in random-effects models. We will also conduct subgroup analyses and note other important quantitative findings, such as cost reduction, and qualitative findings, such as patient satisfaction. We will also assess study quality and risk of bias and metabias. ETHICS AND DISSEMINATION: Ethics approval is not required for this systematic review of previously published literature. The results of the systematic review will be broadly disseminated via conference presentations, multidisciplinary workshops and peer-reviewed publications.

PMID- 29444787 TI - Randomised controlled pragmatic clinical trial evaluating the effectiveness of a discharge follow-up phone call on 30-day hospital readmissions: balancing pragmatic and explanatory design considerations. AB - INTRODUCTION: Hospital readmissions within 30 days are a healthcare quality problem associated with increased costs and poor health outcomes. Identifying interventions to improve patients' successful transition from inpatient to outpatient care is a continued challenge. METHODS AND ANALYSIS: This is a single centre pragmatic randomised and controlled clinical trial examining the effectiveness of a discharge follow-up phone call to reduce 30-day inpatient readmissions. Our primary endpoint is inpatient readmission within 30 days of hospital discharge censored for death analysed with an intention-to-treat approach. Secondary endpoints included observation status readmission within 30 days, time to readmission, all-cause emergency department revisits within 30 days, patient satisfaction (measured as mean Hospital Consumer Assessment of Healthcare Providers and Systems scores) and 30-day mortality. Exploratory endpoints include the need for assistance with discharge plan implementation among those randomised to the intervention arm and reached by the study nurse, and the number of call attempts to achieve successful intervention delivery. Consistent with the Learning Healthcare System model for clinical research, timeliness is a critical quality for studies to most effectively inform hospital clinical practice. We are challenged to apply pragmatic design elements in order to maintain a high-quality practicable study providing timely results. This type of prospective pragmatic trial empowers the advancement of hospital-wide evidence based practice directly affecting patients. ETHICS AND DISSEMINATION: Study results will inform the structure, objective and function of future iterations of the hospital's discharge follow-up phone call programme and be submitted for publication in the literature.

AB - Primary patellar neoplasms are rare, comprising 0.12% of primary bone tumours; thus, no standardised treatment related to staging exists. 70%-90% of primary patellar neoplasms are benign or intermediate with giant cell tumour (GCT) being the most common. GCTs are locally aggressive, have a high recurrence rate and metastasise in 1%-2%. We report the case of a 23-year-old man with histologically confirmed recurrent GCT of the patella to demonstrate that aggressive surgical management options described in the literature, such as patellectomy with or without complex reconstruction, may be excessive and cause patients undue morbidity. Initially, the patient underwent intralesional curettage with excellent recovery, but presented again with a local recurrence within a year. A further definitive operation was performed which included excision of the inferior pole followed by curettage of the patellar body and artificial bone grafting. The patient made a good recovery and at 5-year follow-up has maintained good function. PMID- 29444788 TI - Assessment of the societal and individual preferences for fertility treatment in Australia: study protocol for stated preference discrete choice experiments. AB - INTRODUCTION: In Australia, societal and individual preferences for funding fertility treatment remain largely unknown. This has resulted in a lack of evidence about willingness to pay (WTP) for fertility treatment by either the general population (the funders) or infertile individuals (who directly benefit). Using a stated preference discrete choice experiment (SPDCE) approach has been suggested as a more appropriate method to inform economic evaluations of fertility treatment. We outline the protocol for an ongoing study which aims to assess fertility treatment preferences of both the general population and infertile individuals, and indirectly estimate their WTP for fertility treatment. METHODS AND ANALYSIS: Two separate but related SPDCEs will be conducted for two population samples-the general population and infertile individuals-to elicit preferences for fertility treatment to indirectly estimate WTP. We describe the qualitative work to be undertaken to design the SPDCEs. We will use D-efficient fractional experimental designs informed by prior coefficients from the pilot surveys. The mode of administration for the SPDCE is also discussed. The final results will be analysed using mixed logit or latent class model. ETHICS AND DISSEMINATION: This study is being funded by the Australian National Health and Medical Research Council (NHMRC) project grant AP1104543 and has been approved by the University of New South Wales Human Research Ethics Committee (HEC 17255) and a fertility clinic's ethics committee. Findings of the study will be disseminated in peer-reviewed journals and presented at various conferences. A lay summary of the results will be made publicly available on the University of New South Wales National Perinatal Epidemiology and Statistics Unit website. Our results will contribute to the development of an evidence-based policy framework for the provision of cost-effective and patient-centred fertility treatment in Australia.

AB - Localised nasopharyngeal amyloidosis is rare. Findings on physical examination and invasive pattern on CT scan can be misleading as it can resemble nasopharyngeal carcinoma. A 64-year-old man presented with left aural fullness for 6 months. The physical examination showed straw-coloured fluid in the left middle ear and irregular reddish mass at the left side of the nasopharynx. The CT scan showed a lobulated heterogeneous mass at the left side of the nasopharynx involving the left Eustachian tube opening. Pathology report was amyloidosis, thus, surgery was done. After a year, there were new foci of amyloidosis at the right side of the nasopharynx, and a repeat surgery was performed. Two years later, the systemic amyloidosis with underlying IgG4-related disease was suspected due to multiple organ involvement. Surgery is the treatment for localised amyloidosis with compressive symptoms. Close follow-up is important after surgical excision due to its recurrence and progression to systemic amyloidosis.

AB - Bladder schwannoma is a rare tumour arising from Schwann cells in nerve sheaths. It is usually more common in patients diagnosed with neurofibromatosis. However, isolated cases of urinary bladder schwannoma is incredibly rare, attributing to <0.1% of bladder tumours. A literature review and analysis revealed that it presents in adulthood, is mostly symptomatic and diagnosis is established histologically. We report a case of isolated bladder schwannoma in 25 year-old female who presented with dyspareunia.

Here we report a 25-year-old young man who presented with pain in the abdomen, recurrent loose stools and hyperglycaemia. On radiological imaging study, there was complete agenesis of the dorsal pancreas except for thin stripe of tissue at the level of the uncinate process. Both exocrinedysfunction and endocrine dysfunction were present in this patient. Patient was supplemented with pancreatic enzyme preparation and insulin. PMID- 29444796 TI - Biopsy-proven multiple sclerosis in an adult patient with atypical craniometaphyseal dysplasia. AB - Craniometaphyseal dysplasia (CMD) is a rare condition characterised by progressive, diffuse hyperostosis of cranial and long bones, with compression of cranial nerves, linked to mutations in ANKH or GJA1 genes. Here we describe an adult case with clinical features of CMD, who developed cerebral expansive lesion of undetermined nature. Brain biopsy revealed active demyelinating lesions, consistent with multiple sclerosis. The genetic screening of target genes for CMD (ANKH and GJA1) resulted negative in this patient. The peculiar clinical association and the negativity of genetic analyses allow to hypothesise that other genetic causes, not already known, are responsible for the combination of these pathological conditions. Future studies aim to identify the genetic causes of CMD, which will be important to further understand the pathogenetic mechanism of this rare and invalidating disease.

PMID- 29444801 TI - Widespread and precise reprogramming of yeast protein-genome interactions in response to heat shock. AB - Gene expression is controlled by a variety of proteins that interact with the genome. Their precise organization and mechanism of action at every promoter remains to be worked out. To better understand the physical interplay among genome-interacting proteins, we examined the temporal binding of a functionally diverse subset of these proteins: nucleosomes (H3), H2AZ (Htz1), SWR (Swr1), RSC (Rsc1, Rsc3, Rsc58, Rsc6, Rsc9, Sth1), SAGA (Spt3, Spt7, Ubp8, Sgf11), Hsf1, TFIID (Spt15/TBP and Taf1), TFIIB (Sua7), TFIIH (Ssl2), FACT (Spt16), Pol II (Rpb3), and Pol II carboxyl-terminal domain (CTD) phosphorylation at serines 2, 5, and 7. They were examined under normal and acute heat shock conditions, using the ultrahigh resolution genome-wide ChIP-exo assay in Saccharomyces cerevisiae Our findings reveal a precise positional organization of proteins bound at most genes, some of which rapidly reorganize within minutes of heat shock. This includes more precise positional transitions of Pol II CTD phosphorylation along the 5' ends of genes than previously seen. Reorganization upon heat shock includes colocalization of SAGA with promoter-bound Hsf1, a change in RSC subunit enrichment from gene bodies to promoters, and Pol II accumulation within promoter/+1 nucleosome regions. Most of these events are widespread and not necessarily coupled to changes in gene expression. Together, these findings reveal protein-genome interactions that are robustly reprogrammed in precise and uniform ways far beyond what is elicited by changes in gene expression. PMID- 29444802 TI - Building Support for Adolescent Sexuality and Reproductive Health Education and Responding to Resistance in Conservative Contexts: Cases From Pakistan. AB - BACKGROUND: Despite international recommendations and supportive evidence, there are few examples of scaled-up and sustained programs to provide adolescents with sexuality education. Moreover, despite acknowledgment that building community support and responding to resistance are key challenges, there is a lack of detailed discussion on specific programmatic strategies to address these issues. OBJECTIVES: This article reviews the work of 2 organizations-Aahung and Rutgers Pakistan-that are successfully implementing large-scale sexuality education programs in Pakistan, collectively reaching more than 500,000 students. This review aims to answer the following questions: (1) How did Aahung and Rutgers Pakistan work to understand Pakistani society and culture and shape their programs to build community support? (2) How did Aahung and Rutgers Pakistan overcome resistance to their efforts? METHODS: We reviewed program documents and publications, synthesized key themes, identified questions of interest, and engaged key informants from Aahung and Rutgers Pakistan's leadership. RESULTS: The success of Aahung and Rutgers Pakistan was grounded in their readiness to understand the nuanced context within the communities, collaborate with groups of stakeholders-including parents, school officials, religious leaders, media personnel, and adolescents themselves-to ensure support, and stand up to forces of resistance to pursue their goals. Specific strategies included working with communities to select content, tactfully selecting and framing issues with careful consideration for sensitivities, engaging adolescents' influencers, strengthening media presence, showcasing school programs to increase understanding and transparency, and choosing opportune times to introduce messages. CONCLUSION: The successful strategies used by Aahung and Rutgers Pakistan to promote adolescent sexual and reproductive health through sexuality education can inform programs worldwide. Additionally, the programmatic weaknesses identified can guide future planning and action by Aahung and Rutgers Pakistan. We call on other programs to continue sharing challenges, specifically related to resistance, with sexuality education programs in order to develop a toolbox of additional strategies for community uptake.

PMID- 29444804 TI - Partitioning the Pleiotropy Between Coronary Artery Disease and Body Mass Index Reveals the Importance of Low Frequency Variants and Central Nervous System Specific Functional Elements. AB - BACKGROUND: The objective of this study is to investigate the extent and nature of pleiotropy between coronary artery disease (CAD) and body mass index (BMI). METHODS: We examined the contribution of genome-wide single-nucleotide polymorphisms (minor allele frequency >=0.01) to co-occurrence of CAD and BMI in a sample of genetically unrelated 8041 subjects (genetic resemblance <=0.025) of European ancestry using mixed-linear-models. We further partitioned the estimated pleiotropy according to biological features to gain insight into the nature of pleiotropy between CAD and BMI. RESULTS: We found significant (P<0.0001) positive genetic correlation between CAD and BMI (rg =0.60). The estimated pleiotropy explained 68% of phenotypic correlation, and it was not proportionally distributed across the chromosomes; notably, chromosome 10 contributed more; whereas, chromosomes 11 and 14 contributed less to pleiotropy than expected given their chromosomal length. We noted that a large proportion (63%; P=0.002) of the pleiotropy is attributed to single-nucleotide polymorphisms with low allele frequency (minor allele frequency <0.05). Of note, pleiotropy was enriched among central nervous system genes and genes of metabolic pathways. Further analyses revealed that these effects are more pronounced in the proopiomelanocortin pathway and genes involved in carbohydrate metabolism. After genome-wide association study meta-analysis, only single-nucleotide polymorphisms downstream of the MC4R gene were found concordantly associated with (P<5*10-8) BMI and CAD with lead single-nucleotide polymorphism being rs663129 (combined P=2.7*10-65). Finally, partitioning the pleiotropy according to functional elements pointed to the importance of superenhancers and notably brain-specific superenhancers. CONCLUSIONS: Genome-wide pleiotropy substantially contributes to co-occurrence of CAD and obesity, and it is highly enriched among low frequency variants and central nervous system-specific functional elements. PMID- 29444807 TI - Hypoxic Challenge Testing (Fitness to Fly) in children with complex congenital heart disease. AB - OBJECTIVE: Commercial airplanes fly with an equivalent cabin fraction of inspired oxygen of 0.15, leading to reduced oxygen saturation (SpO2) in passengers. How this affects children with complex congenital heart disease (CHD) is unknown. We conducted Hypoxic Challenge Testing (HCT) to assess need for inflight supplemental oxygen. METHODS: Children aged <16 years had a standard HCT. They were grouped as (A) normal versus abnormal baseline SpO2 (>=95% vs <95%) and (B) absence versus presence of an actual/potential right-to-left (R-L) shunt. We measured SpO2, heart rate, QT interval corrected for heart rate and partial pressure of carbon dioxide measured transcutaneously (PtcCO2). A test failed when children with (1) normal baseline SpO2 desaturated to 85%, (2) baseline SpO285% 94% desaturated by 15% of baseline; and (3) baseline SpO275%-84% desaturated to 70%. RESULTS: There were 68 children, mean age 3.3 years (range 10 weeks-14.5 years). Children with normal (n=36) baseline SpO2 desaturated from median 99% to 91%, P<0.0001, and 3/36 (8%) failed the test. Those with abnormal baseline SpO2 (n=32) desaturated from median 84% to 76%, P<0.0001, and 5/32 (16%) failed (no significant difference between groups). Children with no R-L shunt (n=25) desaturated from median 99% to 93%, P<0.0001, but 0/25 failed. Those with an actual/potential R-L shunt (n=43) desaturated from median 87% to 78%, P<0.0001, and 8/43 (19%) failed (difference between groups P<0.02). PtcCO2, heart rate and QT interval corrected for heart rate were unaffected by the hypoxic state. CONCLUSIONS: This is the first evidence to help guide which children with CHD need a preflight HCT. We suggest all children with an actual or potential R-L shunt should be tested. PMID- 29444805 TI - A Reassessment of Genes Modulating Aging in Mice Using Demographic Measurements of the Rate of Aging. AB - Many studies have reported genetic interventions that have an effect on mouse life span; however, it is crucial to discriminate between manipulations of aging and aging-independent causes of life extension. Here, we used the Gompertz equation to determine whether previously reported aging-related mouse genes statistically affect the demographic rate of aging. Of 30 genetic manipulations previously reported to extend life span, for only two we found evidence of retarding demographic aging: Cisd2 and hMTH1 Of 24 genetic manipulations reported to shorten life span and induce premature aging features, we found evidence of five accelerating demographic aging: Casp2, Fn1, IKK-beta, JunD, and Stub1 Overall, our reassessment found that only 15% of the genetic manipulations analyzed significantly affected the demographic rate of aging as predicted, suggesting that a relatively small proportion of interventions affecting longevity do so by regulating the rate of aging. By contrast, genetic manipulations affecting longevity tend to impact on aging-independent mortality. Our meta-analysis of multiple mouse longevity studies also reveals substantial variation in the controls used across experiments, suggesting that a short life span of controls is a potential source of bias. Overall, the present work leads to a reassessment of genes affecting the aging process in mice, with broad implications for our understanding of the genetics of mammalian aging and which genes may be more promising targets for drug discovery. PMID- 29444806 TI - Multiple Applications of a Transient CRISPR-Cas9 Coupled with Electroporation (TRACE) System in the Cryptococcus neoformans Species Complex. AB - Cryptococcus neoformans is a fungal pathogen that claims hundreds of thousands of lives annually. Targeted genetic manipulation through biolistic transformation in C. neoformans drove the investigation of this clinically important pathogen at the molecular level. Although costly and inefficient, biolistic transformation remains the major method for editing the Cryptococcus genome as foreign DNAs introduced by other methods such as electroporation are predominantly not integrated into the genome. Although the majority of DNAs introduced by biolistic transformation are stably inherited, the transformation efficiency and the homologous integration rate (~1-10%) are low. Here, we developed a Transient CRISPR (clustered regularly interspaced short palindromic repeat)-Cas9 coupled with Electroporation (TRACE) system for targeted genetic manipulations in the C. neoformans species complex. This method took advantages of efficient genome integration due to double-strand breaks created at specific sites by the transient CRISPR-Cas9 system and the high transformation efficiency of electroporation. We demonstrated that TRACE can efficiently generate precise single-gene deletion mutants using the ADE2 locus as an example. This system can also effectively delete multiple genes in a single transformation, as evident by the successful generation of quadruple mfalpha1Delta2Delta3Delta4Delta mutants. In addition to generating gene deletion mutants, we complemented the ade2Delta mutant by integrating a wild-type ADE2 allele at the "safe haven" region (SH2) via homologous recombination using TRACE. Interestingly, introduced DNAs can be inserted at a designated genetic site without any homologous sequences, opening up numerous other applications. We expect that TRACE, an efficient, versatile, and cost-effective gene editing approach, will greatly accelerate research in this field.

AB - BACKGROUND: It is advocated that heterotaxy should be segregated into right or left isomerism according to atrial appendage morphology. However, atrial situs determination is often based on the pattern of associated findings rather than on atrial morphology itself, which can be difficult to define. The objective was to assess how often concordant patterns of isomerism classified by atrial appendage morphology, bronchopulmonary pattern, and splenic status are breached using cardiac magnetic resonance or computed tomography. The secondary objective was to determine the feasibility of defining atrial appendage morphology using cardiac magnetic resonance or computed tomography. METHODS AND RESULTS: Retrospective review of 114 pediatric patients (median, 2.4 years; range, 1 day-17.9 years) with heterotaxy who underwent cardiac magnetic resonance or computed tomography was performed to evaluate atrial appendage, bronchopulmonary, and visceral organ arrangements. Atrial appendage and splenic anatomy were not definable in 17 of 114 (15%) and 4 of 114 (3.5%) patients, respectively. In the remaining 93 patients, 39% had classic right isomerism (bilateral right atrial appendages, right bronchopulmonary pattern, and asplenia) and 40% had classic left isomerism (bilateral left atrial appendages, left bronchopulmonary pattern, and polysplenia). Classic pattern of isomerism was breached in 20 of 93 (21.5%) patients: 13 (65%) displayed incongruent abdominal situs, 5 (25%) incongruent bronchial situs, 1 (5%) had discrepant appendage morphology, and 1 (5%) incongruent situs at all levels. CONCLUSIONS: Atrial appendage morphology is difficult to assess and not always indicative of bronchopulmonary or abdominal situs. Discordance between bronchopulmonary branching, atrial appendage arrangement, and splenic status was identified in >20% patients with heterotaxy. Independent description of each organ system is required when arrangements are disharmonious among different organ systems.

AB - The flowers of major cereals are arranged on reproductive branches known as spikelets, which group together to form an inflorescence. Diversity for inflorescence architecture has been exploited during domestication to increase crop yields, and genetic variation for this trait has potential to further boost grain production. Multiple genes that regulate inflorescence architecture have been identified by studying alleles that modify gene activity or dosage; however, little is known in wheat. Here, we show TEOSINTE BRANCHED1 (TB1) regulates inflorescence architecture in bread wheat (Triticum aestivum) by investigating lines that display a form of inflorescence branching known as "paired spikelets." We show that TB1 interacts with FLOWERING LOCUS T1 and that increased dosage of TB1 alters inflorescence architecture and growth rate in a process that includes reduced expression of meristem identity genes, with allelic diversity for TB1 found to associate genetically with paired spikelet development in modern cultivars. We propose TB1 coordinates formation of axillary spikelets during the vegetative to floral transition and that alleles known to modify dosage or function of TB1 could help increase wheat yields.

AB - BACKGROUND AND OBJECTIVE: Neonatal hypothermia is common in low birth weight (LBW) (<2500 g) and late-preterm infants (LPIs) (34 0/7-36 6/7 weeks' gestation). It can be a contributory factor for newborn admission to a NICU, resulting in maternal-infant separation and increased resource use. Our objective was to study the efficacy of a quality-improvement bundle of hypothermia preventive measures for LPIs and/or LBW infants in a mother-infant unit. METHODS: We conducted plan do-study-act (PDSA) cycles aimed at decreasing environmental hypothermia for LPIs and/or LBW infants in a mother-infant unit with no other indications for NICU level care. Interventions included using warm towels after delivery, a risk identification card, an occlusive hat, delayed timing of first bath, submersion instead of sponge-bathing, and conducting all assessments under a radiant warmer during the initial hours of life. We implemented these interventions in 3 PDSA cycles and followed hypothermia rates by using statistical process control methods. RESULTS: The baseline mean monthly hypothermia rate among mother-infant unit LPIs and/or LBW infants was 29.8%. Postintervention, the rate fell to 13.3% (-16.5%; P = .002). This decrease occurred in a stepwise fashion in conjunction with the PDSA cycles. In the final, full-intervention period, the rate was 10.0% (-19.8%; P = .0003). A special-cause signal shift was observed in this final period. CONCLUSIONS: Targeted interventions can significantly reduce hypothermia in otherwise healthy LPIs and/or LBW newborns and allow them to safely remain in a mother-infant unit. If applied broadly, such preventive practices could decrease preventable hypothermia in high-risk populations. PMID- 29444815 TI - Molecular mechanisms of missense mutations that generate ectopic N-glycosylation sites in coagulation factor VIII. AB - N-glycosylation is a common posttranslational modification of secreted and membrane proteins, catalyzed by the two enzymatic isoforms of the oligosaccharyltransferase, STT3A and STT3B. Missense mutations are the most common mutations in inherited diseases; however, missense mutations that generate extra, non-native N-glycosylation sites have not been well characterized. Coagulation factor VIII (FVIII) contains five consensus N-glycosylation sites outside its functionally dispensable B domain. We developed a computer program that identified hemophilia A mutations in FVIII that can potentially create ectopic glycosylation sites. We determined that 18 of these ectopic sites indeed become N-glycosylated. These sites span the domains of FVIII and are primarily associated with a severe disease phenotype. Using STT3A and STT3B knockout cells, we determined that ectopic glycosylation exhibited different degrees of dependence on STT3A and STT3B. By separating the effects of ectopic N glycosylation from those due to underlying amino acid changes, we showed that ectopic glycans promote the secretion of some mutants, but impair the secretion of others. However, ectopic glycans that enhanced secretion could not functionally replace a native N-glycan in the same domain. Secretion-deficient mutants, but not mutants with elevated secretion levels, show increased association with the endoplasmic reticulum chaperones BiP (immunoglobulin heavy chain-binding protein) and calreticulin. Though secreted to different extents, all studied mutants exhibited lower relative activity than wild-type FVIII. Our results reveal differential impacts of ectopic N-glycosylation on FVIII folding, trafficking and activity, which highlight complex disease-causing mechanisms of FVIII missense mutations. Our findings are relevant to other secreted and membrane proteins with mutations that generate ectopic N-glycans.

PMID- 29444814 TI - Plastid Translation Elongation Factor Tu Is Prone to Heat-Induced Aggregation Despite Its Critical Role in Plant Heat Tolerance. AB - Translation elongation factor Tu (EF-Tu) is a conserved GTP-binding protein essential for protein translation in prokaryotes and in eukaryotic mitochondria and plastids. EF-Tu also has a GTP/GDP-independent chaperone activity that may function in acclimation to heat. Here, we report that the Arabidopsis (Arabidopsis thaliana) plastid EF-Tu, Rabe1b, rapidly becomes insoluble at temperatures as low as 35 degrees C in vitro and 41 degrees C in vivo, with more than 90% aggregation after 9 h at 45 degrees C in vivo. Based on its established function in protein translation, heat-induced aggregation likely inactivates Rabe1b. To determine the effect of heat-induced aggregation, we isolated an Arabidopsis rabe1b knockdown mutant and discovered it to be highly compromised in heat tolerance. Overexpression of constitutive GTP- or GDP-bound mutant forms of Rabe1b in Arabidopsis and virus-induced silencing of Rabe1b in tomato (Solanum lycopersicum) also reduced heat tolerance. Compromised heat tolerance in the Arabidopsis rabe1b mutant and in the lines overexpressing constitutive GTP- or GDP-bound mutant Rabe1b proteins was associated with reduced plastid translation under heat stress. The Arabidopsis rabe1b mutant also showed compromised heat induced expression of HsfA2 and its target genes. Constitutive overexpression of HsfA2 activated its target genes but only partially restored the heat tolerance of the rabe1b mutant. These results strongly suggest that the plastid protein EF Tu is heat sensitive and acts as a critical limiting factor in plant heat stress responses, primarily functioning in plastid protein translation but also in protein folding and retrograde signaling of nuclear heat-responsive gene expression. PMID- 29444818 TI - Sox7 promotes high-grade glioma by increasing VEGFR2-mediated vascular abnormality. AB - High-grade glioma (HGG) is highly angiogenic, but antiangiogenic therapy has transient clinical benefit in only a fraction of patients. Vascular regulators of these heterogeneous responses remain undetermined. We found up-regulation of Sox7 and down-regulation of Sox17 in tumor endothelial cells (tECs) in mouse HGG. Sox7 deletion suppressed VEGFR2 expression, vascular abnormality, hypoxia-driven invasion, regulatory T cell infiltration, and tumor growth. Conversely, Sox17 deletion exacerbated these phenotypes by up-regulating Sox7 in tECs. Anti-VEGFR2 antibody treatment delayed tumor growth by normalizing Sox17-deficient abnormal vessels with high Sox7 levels but promoted it by regressing Sox7-deficient vessels, recapitulating variable therapeutic responses to antiangiogenic therapy in HGG patients. Our findings establish that Sox7 promotes tumor growth via vessel abnormalization, and its level determines the therapeutic outcome of VEGFR2 inhibition in HGG. In 189 HGG patients, Sox7 expression was heterogeneous in tumor vessels, and high Sox7 levels correlated with poor survival, early recurrence, and impaired vascular function, emphasizing the clinical relevance of Sox7 in HGG. PMID- 29444819 TI - BACE1 deletion in the adult mouse reverses preformed amyloid deposition and improves cognitive functions. AB - BACE1 initiates the generation of the beta-amyloid peptide, which likely causes Alzheimer's disease (AD) when accumulated abnormally. BACE1 inhibitory drugs are currently being developed to treat AD patients. To mimic BACE1 inhibition in adults, we generated BACE1 conditional knockout (BACE1fl/fl) mice and bred BACE1fl/fl mice with ubiquitin-CreER mice to induce deletion of BACE1 after passing early developmental stages. Strikingly, sequential and increased deletion of BACE1 in an adult AD mouse model (5xFAD) was capable of completely reversing amyloid deposition. This reversal in amyloid deposition also resulted in significant improvement in gliosis and neuritic dystrophy. Moreover, synaptic functions, as determined by long-term potentiation and contextual fear conditioning experiments, were significantly improved, correlating with the reversal of amyloid plaques. Our results demonstrate that sustained and increasing BACE1 inhibition in adults can reverse amyloid deposition in an AD mouse model, and this observation will help to provide guidance for the proper use of BACE1 inhibitors in human patients. PMID- 29444820 TI - A modified, hypoallergenic variant of the Ricinus communis Ric c1 protein retains biological activity. AB - Ric c1, an allergenic protein from Ricinus communis , is an insect alpha-amylase inhibitor that has become an occupational allergen. Ric c1 can cross-react with allergens from wheat, soybean, peanut, shrimp, fish, gluten, house dust, tobacco, and air fungus, thereby amplifying the concern and risks caused by Ricinus allergens. Two continuous IgE-binding epitopes were identified in Ric c1, both containing glutamic acid residues involved in IgE-binding and allergic challenges. We produced recombinant Ric c1 (rRic c1) in Escherichia coli , using primers from foliar R. communis DNA, and a mutant (Glu-Leu) recombinant protein (mrRic c1) in the same system using synthetic genes. rRic c1 preserved both allergenic and alpha-amylase inhibitory properties, and mrRic c1 drastically reduced allergenic properties. These results can help to establish meaningful relationships between structure, defense and allergenicity, important steps for producing engineered plants and developing new approaches for immunotherapy. PMID- 29444821 TI - A fusion protein composed of the DSL domain of Dll1 and RGD motif protects cryptic stem cells in irradiation injury. AB - Intestine is vulnerable to irradiation injury, which induces cell death and compromises regeneration of intestinal crypts. It is well accepted that cryptic stem cells, which are responsible for cryptic regeneration under physiological and pathological conditions, are controlled by multiple cell-intrinsic and environmental signals such as Notch signaling. Therefore, in the present study, we tested whether a soluble Notch ligand tethered to endothelial cells-mD1R-the Delta-Serrate-Lag2 (DSL) domain of mouse Notch ligand Delta-like1 fused with a RGD motif could protect cryptic cells from irradiation-induced intestinal injury. The result showed that administration of mD1R, which activated Notch signaling in intestinal cells, ameliorated loss of body weight and reduction of cryptic structures in intestine after total body irradiation (TBI) in mice. Histological staining showed that injection of mD1R after TBI promoted cryptic cell proliferation and reduced cell apoptosis in crypts. Immunofluorescence staining and reverse transcription (RT)-PCR showed that mD1R increased the level of Lgr5, Bmi1, Olfactomedin-4 (OLFM4), and IRIG1 in crypts, suggesting a protective effect on cryptic stem and progenitor cells after irradiation. Moreover, we found that administration of mD1R increased the number of Paneth cells and the mRNA level of Defa1, and the number Alcian Blue+ Goblet cells decreased first and then increased after irradiation, suggesting that mD1R promoted the maturation of the intestinal crypt after irradiation injury. Our data suggested that mD1R could serve as a therapeutic agent for the treatment of irradiation-induced intestinal injury. PMID- 29444823 TI - Introduction to the Thematic Minireview Series: Green biological chemistry. AB - Plants and their green cousins cyanobacteria and algae use sunlight to drive the chemistry that lets them grow, survive, and perform an amazing range of biochemical reactions. The ability of these organisms to use a freely available energy source makes them attractive as sustainable and renewable platforms for more than just food production. They are also a source of metabolic tools for engineering microbes for "green" chemistry. This Thematic Minireview Series discusses how green organisms capture light and protect their photosynthetic machinery from too much light; new structural snapshots of the clock complex that orchestrates signaling during the light/dark cycle; challenges for improving stress responses in crops; harnessing cyanobacteria as biofactories; and efforts to engineer microbes for "green" biopolymer production. PMID- 29444822 TI - The protein kinase PERK/EIF2AK3 regulates proinsulin processing not via protein synthesis but by controlling endoplasmic reticulum chaperones. AB - Loss-of-function mutations of the protein kinase PERK (EIF2AK3) in humans and mice cause permanent neonatal diabetes and severe proinsulin aggregation in the endoplasmic reticulum (ER), highlighting the essential role of PERK in insulin production in pancreatic beta cells. As PERK is generally known as a translational regulator of the unfolded protein response (UPR), the underlying cause of these beta cell defects has often been attributed to derepression of proinsulin synthesis, resulting in proinsulin overload in the ER. Using high resolution imaging and standard protein fractionation and immunological methods we have examined the PERK-dependent phenotype more closely. We found that whereas proinsulin aggregation requires new protein synthesis, global protein and proinsulin synthesis are down-regulated in PERK-inhibited cells, strongly arguing against proinsulin overproduction being the root cause of their aberrant ER phenotype. Furthermore, we show that PERK regulates proinsulin proteostasis by modulating ER chaperones, including BiP and ERp72. Transgenic overexpression of BiP and BiP knockdown (KD) both promoted proinsulin aggregation, whereas ERp72 overexpression and knockdown rescued it. These findings underscore the importance of ER chaperones working in concert to achieve control of insulin production and identify a role for PERK in maintaining a functional balance among these chaperones.

This subfamily contains both homodimeric kinesins whose catalytic domains result from the same gene product and heterodimeric kinesins with motor domains derived from two different gene products. In this Minireview, we focus on the progress to define the biochemical and biophysical properties of the kinesin-2 family members. Our understanding of their mechanochemical capabilities has been advanced by the ability to identify the kinesin-2 genes in multiple species, expression and purification of these motors for single-molecule and ensemble assays, and development of new technologies enabling quantitative measurements of kinesin activity with greater sensitivity. PMID- 29444825 TI - Structure and function of a novel periplasmic chitooligosaccharide-binding protein from marine Vibrio bacteria. AB - Periplasmic solute-binding proteins in bacteria are involved in the active transport of nutrients into the cytoplasm. In marine bacteria of the genus Vibrio, a chitooligosaccharide-binding protein (CBP) is thought to be the major solute-binding protein controlling the rate of chitin uptake in these bacteria. However, the molecular mechanism of the CBP involvement in chitin metabolism has not been elucidated. Here, we report the structure and function of a recombinant chitooligosaccharide-binding protein from Vibrio harveyi, namely VhCBP, expressed in Escherichia coli Isothermal titration calorimetry revealed that VhCBP strongly binds shorter chitooligosaccharides ((GlcNAc) n , where n = 2, 3, and 4) with affinities that are considerably greater than those for glycoside hydrolase family 18 and 19 chitinases but does not bind longer ones, including insoluble chitin polysaccharides. We also found that VhCBP comprises two domains with flexible linkers and that the domain-domain interface forms the sugar-binding cleft, which is not long extended but forms a small cavity. (GlcNAc)2 bound to this cavity, apparently triggering a closed conformation of VhCBP. Trp-363 and Trp-513, which stack against the two individual GlcNAc rings, likely make a major contribution to the high affinity of VhCBP for (GlcNAc)2 The strong chitobiose binding, followed by the conformational change of VhCBP, may facilitate its interaction with an active-transport system in the inner membrane of Vibrio species. PMID- 29444826 TI - Polymerase theta-helicase efficiently unwinds DNA and RNA-DNA hybrids. AB - POLQ is a unique multifunctional replication and repair gene that encodes for a N terminal superfamily 2 helicase and a C-terminal A-family polymerase. Although the function of the polymerase domain has been investigated, little is understood regarding the helicase domain. Multiple studies have reported that polymerase theta-helicase (Poltheta-helicase) is unable to unwind DNA. However, it exhibits ATPase activity that is stimulated by single-stranded DNA, which presents a biochemical conundrum. In contrast to previous reports, we demonstrate that Poltheta-helicase (residues 1-894) efficiently unwinds DNA with 3'-5' polarity, including DNA with 3' or 5' overhangs, blunt-ended DNA, and replication forks. Poltheta-helicase also efficiently unwinds RNA-DNA hybrids and exhibits a preference for unwinding the lagging strand at replication forks, similar to related HELQ helicase. Finally, we find that Poltheta-helicase can facilitate strand displacement synthesis by Poltheta-polymerase, suggesting a plausible function for the helicase domain. Taken together, these findings indicate nucleic acid unwinding as a relevant activity for Poltheta in replication repair. PMID- 29444828 TI - Diagnosing Invasive Candidiasis. AB - Cultures are negative in ~50% of invasive candidiasis. Data are emerging for the performance of nonculture tests such as mannan/antimannan, Candida albicans germ tube antibody, 1,3-beta-d-glucan, PCR, and the T2Candida panel in diagnosing both candidemia and deep-seated candidiasis. In most settings, positive predictive values of nonculture test are low, and negative predictive values are high. For tests to be useful, clinicians must understand the pretest likelihood of invasive candidiasis and test performance for the most common disease manifestation in a given patient. This paper reviews nonculture Candida diagnostics and discusses how they might be used effectively in patient care. PMID- 29444827 TI - Site-specific polyubiquitination differentially regulates parathyroid hormone receptor-initiated MAPK signaling and cell proliferation. AB - G protein-coupled receptor (GPCR) signaling and trafficking are essential for cellular function and regulated by phosphorylation, beta-arrestin, and ubiquitination. The GPCR parathyroid hormone receptor (PTHR) exhibits time dependent reversible ubiquitination. The exact ubiquitination sites in PTHR are unknown, but they extend upstream of its intracellular tail. Here, using tandem MS, we identified Lys388 in the third loop and Lys484 in the C-terminal tail as primary ubiquitination sites in PTHR. We found that PTHR ubiquitination requires beta-arrestin and does not display a preference for beta-arrestin1 or -2. PTH stimulated PTHR phosphorylation at Thr387/Thr392 and within the Ser489-Ser493 region. Such phosphorylation events may recruit beta-arrestin, and we observed that chemically or genetically blocking PTHR phosphorylation inhibits its ubiquitination. Specifically, Ala replacement at Thr387/Thr392 suppressed beta arrestin binding and inhibited PTHR ubiquitination, suggesting that PTHR phosphorylation and ubiquitination are interdependent. Of note, Lys-deficient PTHR mutants promoted normal cAMP formation, but exhibited differential mitogen activated protein kinase (MAPK) signaling. Lys-deficient PTHR triggered early onset and delayed ERK1/2 signaling compared with wildtype PTHR. Moreover, ubiquitination of Lys388 and Lys484 in wildtype PTHR strongly decreased p38 signaling, whereas Lys-deficient PTHR retained signaling comparable to unstimulated wildtype PTHR. Lys-deficient, ubiquitination-refractory PTHR reduced cell proliferation and increased apoptosis. However, elimination of all 11 Lys residues in PTHR did not affect its internalization and recycling. These results pinpoint the ubiquitinated Lys residues in PTHR controlling MAPK signaling and cell proliferation and survival. Our findings suggest new opportunities for targeting PTHR ubiquitination to regulate MAPK signaling or manage PTHR-related disorders. PMID- 29444829 TI - Multiplex Immunochromatographic Detection of OXA-48, KPC, and NDM Carbapenemases: Impact of Inoculum, Antibiotics, and Agar. AB - For the rapid detection of carbapenemase-producing Enterobacteriaceae (CPE), immunochromatographic lateral flow tests (ICT) have recently been developed. The aim of this study was to assess the new multiplex ICT Resist-3 O.K.N. and to investigate if it can be performed directly from susceptibility testing plates. Additionally, the impact of the inoculum and carbapenem disks on sensitivity and specificity was evaluated. The new ICT was challenged using 63 carbapenem resistant Enterobacteriaceae (CRE) isolates, including 51 carbapenemase producers. It was assessed under five different conditions directly from Mueller Hinton agar (MHA): 1 MUl or 10 MUl of inoculum harvested in the absence of antibiotic pressure or 1 MUl taken from the inhibition zone of either an ertapenem, imipenem, or meropenem disk. The sensitivity of the ICT was 100% for OXA-48-like and KPC carbapenemases and 94.4% for the NDM carbapenemase with the 1 MUl inoculum. When harvested adjacent to a carbapenem disk, the sensitivity increased to 100%. Additionally, with zinc-supplemented MHA, both the sensitivity increased and the NDM band became visible faster (mean time, 8 +/- 3.9 min for MHA compared to 1.9 +/- 1.5 min for MHA plus zinc; P = 0.0016). The specificity of the ICT was 100%. The Resist-3 O.K.N. ICT is a sensitive and rapid test for the detection of three highly prevalent carbapenemases. However, false-negative results for NDM can occur. We recommend an inoculum of 1 MUl that is harvested adjacent to an ertapenem or meropenem disk and the use of agars with sufficient zinc content to achieve the best performance. PMID- 29444830 TI - Characterization of a Vesivirus Associated with an Outbreak of Acute Hemorrhagic Gastroenteritis in Domestic Dogs. AB - Four of eleven affected dogs died despite aggressive treatment during a 2015 focal outbreak of hemorrhagic gastroenteritis following a stay in a pet housing facility. Routine diagnostic investigations failed to identify a specific cause. Virus isolation from fresh necropsy tissues yielded a calicivirus with sequence homology to a vesivirus within the group colloquially known as the vesivirus 2117 strains that were originally identified as contaminants in CHO cell bioreactors. In situ hybridization and reverse transcription-PCR assays of tissues from the four deceased dogs confirmed the presence of canine vesivirus (CaVV) nucleic acids that localized to endothelial cells of arterial and capillary blood vessels. CaVV nucleic acid corresponded to areas of necrosis and hemorrhage primarily in the intestinal tract, but also in the brain of one dog with nonsuppurative meningoencephalitis. This is the first report of an atypical disease association with a putative hypervirulent vesivirus strain in dogs, as all other known strains of CaVV appear to cause nonclinical infections or relatively mild disease. After identification of the CU-296 vesivirus strain from this outbreak, four additional CaVV strains were amplified from unrelated fecal specimens and archived stocks provided by other laboratories. Broader questions include the origins, reservoir(s), and potential for reemergence and spread of these related CaVVs. PMID- 29444831 TI - HIV-Associated Mycobacterium tuberculosis Bloodstream Infection Is Underdiagnosed by Single Blood Culture. AB - We assessed the additional diagnostic yield for Mycobacterium tuberculosis bloodstream infection (BSI) by doing more than one tuberculosis (TB) blood culture from HIV-infected inpatients. In a retrospective analysis of two cohorts based in Cape Town, South Africa, 72/99 (73%) patients with M. tuberculosis BSI were identified by the first of two blood cultures during the same admission, with 27/99 (27%; 95% confidence interval [CI], 18 to 36%) testing negative on the first culture but positive on the second. In a prospective evaluation of up to 6 blood cultures over 24 h, 9 of 14 (65%) patients with M. tuberculosis BSI had M. tuberculosis grow on their first blood culture; 3 more patients (21%) were identified by a second independent blood culture at the same time point, and the remaining 2 were diagnosed only on the 4th and 6th blood cultures. Additional blood cultures increase the yield for M. tuberculosis BSI, similar to what is reported for nonmycobacterial BSI.

PMID- 29444832 TI - Differential Contributions of Specimen Types, Culturing, and 16S rRNA Sequencing in Diagnosis of Prosthetic Joint Infections. AB - Prosthetic joint failure is mainly caused by infection, aseptic failure (AF), and mechanical problems. Infection detection has been improved with modified culture methods and molecular diagnostics. However, comparisons between modified and conventional microbiology methods are difficult due to variations in specimen sampling. In this prospective, multidisciplinary study of hip or knee prosthetic failures, we assessed the contributions of different specimen types, extended culture incubations, and 16S rRNA sequencing for diagnosing prosthetic joint infections (PJI). Project specimens included joint fluid (JF), bone biopsy specimens (BB), soft-tissue biopsy specimens (STB), and swabs (SW) from the prosthesis, collected in situ, and sonication fluid collected from prosthetic components (PC). Specimens were cultured for 6 (conventional) or 14 days, and 16S rRNA sequencing was performed at study completion. Of the 156 patients enrolled, 111 underwent 114 surgical revisions (cases) due to indications of either PJI (n = 43) or AF (n = 71). Conventional tissue biopsy cultures confirmed PJI in 28/43 (65%) cases and refuted AF in 3/71 (4%) cases; one case was not evaluable. Based on these results, minor diagnostic adjustments were made. Fourteen-day cultures of JF, STB, and PC specimens confirmed PJI in 39/42 (93%) cases, and 16S rRNA sequencing confirmed PJI in 33/42 (83%) cases. One PJI case was confirmed with 16S rRNA sequencing alone and five with cultures of project specimens alone. These findings indicated that JF, STB, and PC specimen cultures qualified as an optimal diagnostic set. The contribution of sequencing to diagnosis of PJI may depend on patient selection; this hypothesis requires further investigation. PMID- 29444834 TI - Accuracy of High-Throughput Nanofluidic PCR-Based Pneumococcal Serotyping and Quantification Assays Using Sputum Samples for Diagnosing Vaccine Serotype Pneumococcal Pneumonia: Analyses by Composite Diagnostic Standards and Bayesian Latent Class Models. AB - The lack of reliable diagnostic tests for detecting vaccine serotype pneumococcal pneumonia (VTPP) remains a challenging issue in pneumococcal vaccine studies. This study assessed the performances of high-throughput nanofluidic PCR-based pneumococcal serotyping and quantification assay methods using sputum samples (the nanofluidic sputum quantitative PCR [Sp-qPCR] assay) to diagnose 13-valent pneumococcal conjugate VTPP compared with the performance of the serotype specific urinary antigen detection (UAD) assay using urine samples. Adult pneumonia patients from Japan were enrolled in this study between September 2012 and August 2014. Sputum samples were subjected to the nanofluidic Sp-qPCR assay, quantitatively cultured, and serotyped by the Quellung reaction (SpQt). Urine samples were tested by the UAD method. The diagnostic performances of these tests were assessed using composite reference standards and Bayesian latent class models (BLCMs). Among 244 total patients, 27 (11.1%) tested positive with the UAD assay, while 16 (6.6%) and 34 (13.9%) tested positive with the SpQt and nanofluidic Sp-qPCR assays, respectively, with a cutoff value of >=104 DNA copies/ml, which showed the maximum value of the Youden index. Using BLCMs, the estimated prevalence for VTPP was 12.9%, and the nanofluidic Sp-qPCR assay demonstrated the best performance (sensitivity, 90.2%; specificity, 96.9%), followed by UAD (sensitivity, 75.6%; specificity, 97.9%) and SpQt (sensitivity, 45.8%; specificity, 99.5%). However, when a higher cutoff value of >=107 DNA copies/ml was applied, the performance of UAD became comparable to that of Sp qPCR. The vaccine serotype-specific pneumococcal DNA load in sputum among UAD positive patients was 3 logs higher than that among UAD-negative patients (P = 0.036). The nanofluidic Sp-qPCR assay may be accurate and useful for detecting VTPP among adults. PMID- 29444835 TI - Retrospective Review of Treponema pallidum PCR and Serology Results: Are Both Tests Necessary? AB - There has been a resurgence of syphilis diagnoses in Australia. We investigated whether our Treponema pallidum PCR test provides any additional diagnostic information over syphilis serology (chemiluminescence immunoassay [CMIA], Treponema pallidum particle agglutination [TPPA] assay, and the rapid plasma reagin [RPR] flocculation test). A retrospective audit of all T. pallidum PCR requests that came through our laboratory from January 2010 to June 2017 was conducted; data collected included age, gender, site of swab, and results from T. pallidum PCR, syphilis serology, and herpes simplex virus 1 (HSV-1) and HSV-2 PCRs. A total of 441 T. pallidum PCR tests were performed; on average, 3 T. pallidum PCRs per month were requested in 2011, and this rate increased to 17.2 requests per month in 2017. A total of 323 patients had both T. pallidum PCR and syphilis serology performed, with 67% of swabs taken from the genitals. T. pallidum PCR gave positive results for 61/323 (19%) patients; of these 61 patients, 59 (97%) also had positive syphilis serology results (T. pallidum PCR sensitivity, 68%; specificity, 99%; positive predictive value, 97%; negative predictive value, 89%). Syphilis serology was positive for 91/323 patients (28%); of these 91 patients, 61 (66%) were also T. pallidum PCR positive (syphilis serology sensitivity, 97%; specificity, 88%; positive predictive value, 60%; negative predictive value, 99%). The Cohen's kappa value was 0.74, indicating substantial agreement between the two tests. Our results show that most patients with positive T. pallidum PCR results also had positive syphilis serology. Therefore, T. pallidum PCR adds little clinical value over serology for the diagnosis of syphilis in certain clinical settings.

The Elecsys Chagas assay is a newly developed, double antigen sandwich assay for use on the Elecsys and cobas e immunoassay analyzers, intended to identify individuals infected with Trypanosoma cruzi, for diagnosis and screening. The performance of the Elecsys Chagas assay was evaluated in comparison with those of other widely used T. cruzi antibody assays, at multiple sites (Europe/Latin America). Relative sensitivity and specificity were assessed by using samples from blood donors, pregnant women, and hospitalized patients from regions where Chagas disease is endemic and from regions of nonendemicity. The Elecsys Chagas assay had an overall relative sensitivity of 100% (n = 674). Overall relative specificities were 99.90% (n = 14,681), 100% (n = 313), and 100% (n = 517) for samples from blood donors, pregnant women, and hospitalized patients, respectively. The analytical specificity was 99.83% (n = 594). The Elecsys Chagas assay detected T. cruzi antibodies in two World Health Organization (WHO) standard T. cruzi reference panels (panels 09/188 and 09/186) at a 1:512 dilution, corresponding to a cutoff sensitivity of approximately 1 mIU/ml. The Elecsys Chagas assay demonstrated robust performance under routine conditions at multiple sites in Europe and Latin America. In contrast to other available Chagas assays, the Elecsys assay uses a reduced number of recombinant T. cruzi antigens, resulting in a significantly smaller number of cross-reactions and improved analytical specificity while being highly sensitive. PMID- 29444837 TI - Whole-Genome Sequence Analysis of Streptococcus pneumoniae Strains That Cause Hospital-Acquired Pneumonia Infections. AB - Streptococcus pneumoniae colonizes the nasopharyngeal mucus in healthy individuals and can cause otitis media, pneumonia, and invasive pneumococcal diseases. In this study, we analyzed S. pneumoniae strains that caused 19 pneumonia episodes in long-term inpatients with severe underlying disease in a hospital during a period of 14 months (from January 2014 to February 2015). Serotyping and whole-genome sequencing analyses revealed that 18 of the 19 pneumonia cases were caused by S. pneumoniae strains belonging to 3 genetically distinct groups: clonal complex 9999 (CC9999), sequence type 282 (ST282), and ST166. The CC9999 and ST282 strains appeared to have emerged separately by a capsule switch from the pandemic PMEN 1 strain (Spain23F-ST81). After all the long-term inpatients were inoculated with the 23-valent pneumococcal polysaccharide vaccine, no other nosocomial pneumonia infections occurred until March 2016. PMID- 29444838 TI - Enzyme polymorphism, oxygen and injury: a lipidomic analysis of flight-induced oxidative damage in a succinate dehydrogenase d (Sdhd)-polymorphic insect. AB - When active tissues receive insufficient oxygen to meet metabolic demand, succinate accumulates and has two fundamental effects: it causes ischemia reperfusion injury while also activating the hypoxia-inducible factor pathway (HIF). The Glanville fritillary butterfly (Melitaea cinxia) possesses a balanced polymorphism in Sdhd, shown previously to affect HIF pathway activation and tracheal morphology and used here to experimentally test the hypothesis that variation in succinate dehydrogenase affects oxidative injury. We stimulated butterflies to fly continuously in a respirometer (3 min duration), which typically caused episodes of exhaustion and recovery, suggesting a potential for cellular injury from hypoxia and reoxygenation in flight muscles. Indeed, flight muscle from butterflies flown on consecutive days had lipidome profiles similar to those of rested paraquat-injected butterflies, but distinct from those of rested untreated butterflies. Many butterflies showed a decline in flight metabolic rate (FMR) on day 2, and there was a strong inverse relationship between the ratio of day 2 to day 1 FMR and the abundance of sodiated adducts of phosphatidylcholines and co-enzyme Q (CoQ). This result is consistent with elevation of sodiated lipids caused by disrupted intracellular ion homeostasis in mammalian tissues after hypoxia-reperfusion. Butterflies carrying the Sdhd M allele had a higher abundance of lipid markers of cellular damage, but the association was reversed in field-collected butterflies, where focal individuals typically flew for seconds at a time rather than continuously. These results indicate that Glanville fritillary flight muscles can be injured by episodes of high exertion, but injury severity appears to be determined by an interaction between SDH genotype and behavior (prolonged versus intermittent flight). PMID- 29444839 TI - Reverse genetics demonstrate the role of mucosal C-type lectins in food particle selection in the oyster Crassostrea virginica. AB - Prey selection governs species interactions and regulates physiological energetics of individuals and populations. Suspension-feeding bivalves represent key species in coastal and estuarine systems for their ecological and economic value. These animals are able to sort and selectively ingest nutritious microalgae from dilute and composite mixtures of particulate matter. This aptitude was suggested to be mediated by interactions between carbohydrates associated with the surface of microalgae and C-type lectins present in mucus covering the feeding organs, although a direct, unequivocal, role of lectins in food sorting in bivalves remains elusive. This study was designed to identify and characterize mucosal C-type lectins from oysters and manipulate the expression of these proteins in order to obtain decisive information regarding their involvement in food choice. Thus, two mucosal C-type lectins (CvML3912 and CvML3914) were identified based on transcriptomic and proteomic information. Transcripts of these lectins were detected in the feeding organs and their expression was upregulated following starvation. Recombinant lectin (rCvML3912) competitively inhibited the binding of commercial mannose/glucose-specific lectins to microalgae. Short Dicer-substrate small interfering RNA (DsiRNA) targeting these two lectins were designed and used to evaluate the effect of gene silencing on food particle sorting. As a result, the abundance of the two cognate transcripts significantly decreased and food sorting ability was significantly reduced among silenced oysters as compared with control animals. Overall, these findings propose a novel concept establishing the role of carbohydrate-protein interactions to provide efficient food particle sorting, and establish a new dimension for the role of evolutionarily conserved mannose/glucose-binding proteins in metazoans. PMID- 29444840 TI - Intestinal alpha-glycosidase transcriptional responses during development and diet adjustment in altricial birds. AB - We describe developmental changes in maltasic activity and its mRNA until adulthood, and in response to an increase in dietary starch. We studied house sparrows (Passer domesticus), which undergo a natural switch from insects to a starch-containing seed diet during development, and zebra finches (Taeniopygia guttata), which have a relatively fixed starchy seed diet during development. In zebra finches, in which maltasic activity increased with age but not with dietary starch, alpha-glycosidase (AG) mRNA was not affected by either age or dietary starch level. In house sparrow nestlings, in which maltasic activity increased with age and with added starch, AG mRNA was higher when birds were fed a diet with added starch but did not increase with age. These results are consistent with the idea that the apparent programmed developmental increase in maltasic activity is not mainly under transcriptional control of AG mRNA, whereas induction of maltasic activity by increased dietary starch is. PMID- 29444841 TI - Measuring metabolic rates of small terrestrial organisms by fluorescence-based closed-system respirometry. AB - We explore a recent, innovative variation of closed-system respirometry for terrestrial organisms, whereby oxygen partial pressure (PO2 ) is repeatedly measured fluorometrically in a constant-volume chamber over multiple time points. We outline a protocol that aligns this technology with the broader literature on aerial respirometry, including the calculations required to accurately convert O2 depletion to metabolic rate (MR). We identify a series of assumptions, and sources of error associated with this technique, including thresholds where O2 depletion becomes limiting, that impart errors to the calculation and interpretation of MR. Using these adjusted calculations, we found that the resting MR of five species of angiosperm seeds ranged from 0.011 to 0.640 ml g-1 h-1, consistent with published seed MR values. This innovative methodology greatly expands the lower size limit of terrestrial organisms that can be measured, and offers the potential for measuring MR changes over time as a result of physiological processes of the organism. PMID- 29444842 TI - Task-specific sensory coding strategies are matched to detection and discrimination performance. AB - The acquisition of sensory information is limited by the neural encoding method used, constraining perceptual abilities. The most relevant aspects of stimuli may change as behavioral context changes, making efficient encoding of information more challenging. Sensory systems must balance rapid detection of a stimulus with perception of fine details that enable discrimination between similar stimuli. Here, we show that in a species of weakly electric fish, Apteronotus leptorhynchus, two coding strategies are employed for these separate behavioral tasks. Using communication signals, we demonstrate a strong correlation between neural coding strategies and behavioral performance on a discrimination task. Extracellular recordings of pyramidal cells within the electrosensory lateral line lobe of alert fish show two distinct response patterns, either burst discharges with little variation between different signals of the same category, or a graded, heterogeneous response that contains sufficient information to discriminate between signals with slight variations. When faced with a discrimination-based task, the behavioral performance of the fish closely matches predictions based on coding strategy. Comparisons of these results with neural and behavioral responses observed in other model systems suggest that our study highlights a general principle in the way sensory systems utilize different neural codes. PMID- 29444843 TI - Testing the parasite mass burden effect on alteration of host behaviour in the Schistocephalus-stickleback system. AB - Many parasites with complex life cycles modify the behaviour of their intermediate host, which has been proposed to increase transmission to their definitive host. This behavioural change could result from the parasite actively manipulating its host, but could also be explained by a mechanical effect, where the physical presence of the parasite affects host behaviour. We created an artificial internal parasite using silicone injections in the body cavity to test this mechanical effect hypothesis. We used the Schistocephalus solidus and threespine stickleback (Gasterosteus aculeatus) system, as this cestode can reach up to 92% of its fish host mass. Our results suggest that the mass burden brought by this macroparasite alone is not sufficient to cause behavioural changes in its host. Furthermore, our results show that wall-hugging (thigmotaxis), a measure of anxiety in vertebrates, is significantly reduced in Schistocephalus-infected sticklebacks, unveiling a new altered component of behaviour that may result from manipulation by this macroparasite. PMID- 29444844 TI - The stomatogastric nervous system of the medicinal leech: its anatomy, physiology and associated aminergic neurons. AB - Blood feeding is an essential and signature activity of the medicinal leech species Hirudo verbana. Despite keen interest in understanding the neuronal substrates of this behavior, a major component of the nervous system associated with feeding has remained overlooked. In this study, for the first time, we report on the presence and characteristics of five stomatogastric ganglia (STGs) comprising the visceral stomatogastric nervous system (STN) of the leech. Although a brief report was published by Ruth Hanke in 1948 indicating that a ring of three ganglia (not five) was associated with the cephalic ganglia, this information was never integrated into subsequent neurobiological studies of feeding. Here, the anatomical features of the STGs are described, as are the morphological and electrophysiological characteristics of neurons originating in them. We also determined that two of the five STGs (STG-1 and STG-3) each contained two relatively large (ca. 40 um diameter) serotonergic neurons. The STN was also enriched with dopaminergic and serotonergic arborizations; however, no intrinsic dopaminergic somata were observed. The trajectory of the serotonergic large lateral (LL) neuron, a command-like cell for feeding, was documented to project directly to the STN and not to the jaw and pharyngeal musculature as previously reported, thus reopening the important question of how the LL cell activates and coordinates biting activity with pharyngeal swallowing. Additional studies revealed that the LL cell is excited by blood serum applied to the lip and is strongly inhibited by dopamine. These findings provide a new foundation for understanding the regulation and modulation of neural networks involved in feeding. PMID- 29444845 TI - Antibacterial activity of male and female sperm-storage organs in ants. AB - Bacteria can damage sperm and thus reduce the reproductive success of both males and females; selection should therefore favour the evolution of antimicrobial protection. Eusocial hymenopterans might be particularly affected by such bacterial infections because of their mating ecology. In both sexes, mating is restricted to a short window early in the adult stage; there are no further chances to mate later in life. Males die shortly after mating, but queens use the acquired sperm to fertilise their eggs for years, sometimes decades. The reproductive success of both sexes is, thus, ultimately sperm-limited, which maintains strong selection for high sperm viability before and after storage. We tested the antibacterial activity of the contents of the male and female sperm storage organs - the accessory testes and the spermatheca, respectively. As our study species, we used the bacterium Escherichia coli and the garden ant Lasius niger, whose queens can live for several decades. Our results provide the first empirical evidence that male and female sperm-storage organs display different antibacterial activity. While the contents of the accessory testes actually enhanced bacterial growth, the contents of the spermatheca strongly inhibited it. Furthermore, mating appears to activate the general immune system in queens. However, antimicrobial activity in both the spermatheca and the control tissue (head-thorax homogenate) declined rapidly post-mating, consistent with a trade off between immunity and reproduction. Overall, this study suggests that ejaculates undergo an immune 'flush' at the time of mating, allowing storage of sperm cells free of bacteria. PMID- 29444846 TI - Differential immune gene expression in sperm storage organs of leaf-cutting ants. AB - Leaf-cutting ant queens mate with multiple males during a single nuptial flight and store sperm for up to two decades. During mating, males transfer sperm from their accessory testes to the queen bursa copulatrix from where it enters the spermatheca, an insect sperm storage organ that has become highly specialized in long-lived ant queens who never re-mate later in life. Long-term storage without the possibility to obtain new sperm creates an immune defence dilemma, because recognition of non-self cells eliminates infections but may also target irreplaceable sperm and reduce lifetime reproductive success. We therefore hypothesized that non-specific immune responses, like pathogen melanization, should be silenced in the spermatheca, because they rely on general non-self recognition, and that specific responses such as antimicrobial peptides are activated instead as they specifically target pathogenic bacteria and/or fungi. The maintenance of uninfected sperm cells by males before mating is not constrained by non-self recognition, meaning immune regulation might be more liberal in male reproductive organs. To test this hypothesis, we measured gene expression of two antimicrobial peptides, abaecin and defensin, and prophenoloxidase, an important enzyme of the melanization pathway, in male accessory glands and testes and in queen bursae copulatrix and spermathecae of Acromyrmex echinatior and Atta colombica leaf-cutting ants. As expected, prophenoloxidase expression was low in reproductive organs that sustain prolonged contact with sperm, whereas antimicrobial peptides showed average to high expression, indicating that leaf-cutting ants invest in specific rather than generalist immune defences for pathogen protection in organs that store sperm. PMID- 29444847 TI - Turnover of muscle lipids and response to exercise differ between neutral and polar fractions in a model songbird, the zebra finch. AB - The turnover rates of tissues and their constituent molecules give us insights into animals' physiological demands and their functional flexibility over time. Thus far, most studies of this kind have focused on protein turnover, and few have considered lipid turnover despite an increasing appreciation of the functional diversity of this class of molecules. We measured the turnover rates of neutral and polar lipids from the pectoralis muscles of a model songbird, the zebra finch (Taeniopygia guttata, N=65), in a 256 day C3/C4 diet shift experiment, with tissue samples taken at 10 time points. We also manipulated the physiological state of a subset of these birds with a 10 week flight training regimen to test the effect of exercise on lipid turnover. We measured lipid delta13C values via isotope ratio mass spectrometry (IRMS) and estimated turnover in different fractions and treatment groups with non-linear mixed-effect regression. We found a significant difference between the mean retention times (tau) of neutral and polar lipids (t119=-2.22, P=0.028), with polar lipids (tau=11.80+/-1.28 days) having shorter retention times than neutral lipids (tau=19.47+/-3.22 days). When all birds were considered, we also found a significant decrease in the mean retention time of polar lipids in exercised birds relative to control birds (difference=-2.2+/-1.83 days, t56=-2.37, P=0.021), but not neutral lipids (difference=4.2+/- 7.41 days, t56=0.57, P=0.57). A larger, more variable neutral lipid pool and the exposure of polar lipids in mitochondrial membranes to oxidative damage and increased turnover provide mechanisms consistent with our results. PMID- 29444848 TI - A miniaturized threshold-triggered acceleration data-logger for recording burst movements of aquatic animals. AB - Although animal-borne accelerometers are effective tools for quantifying the kinematics of animal behaviors, quantifying the burst movements of small and agile aquatic animals remains challenging. To capture the details of burst movements, accelerometers need to sample at a very high frequency, which will inevitably shorten the recording duration or increase the device size. To overcome this problem, we developed a high-frequency acceleration data-logger that can be triggered by a manually defined acceleration threshold, thus allowing the selective measurement of burst movements. We conducted experiments under laboratory and field conditions to examine the performance of the logger. The laboratory experiment using red seabream (Pagrus major) showed that the new logger could measure the kinematics of their escape behaviors. The field experiment using free-swimming yellowtail kingfish (Seriola lalandi) showed that the loggers trigger correctly. We suggest that this new logger can be applied to measure the burst movements of various small and agile animals. PMID- 29444850 TI - Neurovascular dysfunction in dementia - human cellular models and molecular mechanisms. AB - From the earliest stages of development, when cerebral angiogenesis and neurogenesis are entwined, to the end of life, the interplay between vascular and neural systems of the brain is critical in health and disease. Cerebral microvascular endothelial cells constitute the blood-brain barrier and in concert with pericytes or smooth muscle cells, glia and neurons, integrate into a functional neurovascular unit (NVU). This multicellular NVU maintains homoeostasis of the brain's microenvironment by restricting the entry of systemic pathogens and neurotoxins as well as meeting the metabolic demands of neural activity. Recent evidence of cerebral microvascular pathologies in vascular diseases and dementia, including Alzheimer's disease, has challenged the notion that vascular events are merely the consequence of neuronal pathology. This review focuses on molecular mechanisms of neurovascular dysfunction in dementia and outlines currently employed in vitro models to decode such mechanisms. Deciphering neurovascular crosstalk is likely to be more important in understanding the molecular mechanisms of disease than previously anticipated and may offer novel therapeutic opportunities for dementia and related conditions. PMID- 29444849 TI - Amplification of PIP3 signalling by macropinocytic cups. AB - In a role distinct from and perhaps more ancient than that in signal transduction, PIP3 and Ras help to spatially organize the actin cytoskeleton into macropinocytic cups. These large endocytic structures are extended by actin polymerization from the cell surface and have at their core an intense patch of active Ras and PIP3, around which actin polymerizes, creating cup-shaped projections. We hypothesize that active Ras and PIP3 self-amplify within macropinocytic cups, in a way that depends on the structural integrity of the cup. Signalling that triggers macropinocytosis may therefore be amplified downstream in a way that depends on macropinocytosis. This argument provides a context for recent findings that signalling to Akt (an effector of PIP3) is sensitive to cytoskeletal and macropinocytic inhibitors.

PMID- 29444853 TI - Interprofessional Teamwork Innovation Model (ITIM) to promote communication and patient-centred, coordinated care. AB - BACKGROUND: Despite recommendations and the need to accelerate redesign of delivery models to be team-based and patient-centred, professional silos and cultural and structural barriers that inhibit working together and communicating effectively still predominate in the hospital setting. Aiming to improve team based rounding, we developed, implemented and evaluated the Interprofessional Teamwork Innovation Model (ITIM). METHODS: This quality improvement (QI) study was conducted at an academic medical centre. We followed the system's QI framework, FOCUS-PDSA, with Lean as guiding principles. Primary outcomes included 30-day all-cause same-hospital readmissions and 30-day emergency department (ED) visits. The intervention group consisted of patients receiving care on two hospitalist ITIM teams, and patients receiving care from other hospitalist teams were matched with a control group. Outcomes were assessed using difference-in difference analysis. RESULTS: Team members reported enhanced communication and overall time savings. In multivariate modelling, patients discharged from hospitalist teams using the ITIM approach were associated with reduced 30-day same-hospital readmissions with an estimated point OR of 0.56 (95% CI 0.34 to 0.92), but there was no impact on 30-day same-hospital ED visits. Difference-in difference analysis showed that ITIM was not associated with changes in average total direct costs nor average cost per patient day, after adjusting for all other covariates in the models, despite the addition of staff resources in the ITIM model. CONCLUSION: The ITIM approach facilitates a collaborative environment in which patients and their family caregivers, physicians, nurses, pharmacists, case managers and others work and share in the process of care. PMID- 29444854 TI - BET bromodomain proteins regulate enhancer function during adipogenesis. AB - Developmental transitions are guided by master regulatory transcription factors. During adipogenesis, a transcriptional cascade culminates in the expression of PPARgamma and C/EBPalpha, which orchestrate activation of the adipocyte gene expression program. However, the coactivators controlling PPARgamma and C/EBPalpha expression are less well characterized. Here, we show the bromodomain containing protein, BRD4, regulates transcription of PPARgamma and C/EBPalpha. Analysis of BRD4 chromatin occupancy reveals that induction of adipogenesis in 3T3L1 fibroblasts provokes dynamic redistribution of BRD4 to de novo super enhancers proximal to genes controlling adipocyte differentiation. Inhibition of the bromodomain and extraterminal domain (BET) family of bromodomain-containing proteins impedes BRD4 occupancy at these de novo enhancers and disrupts transcription of Pparg and Cebpa, thereby blocking adipogenesis. Furthermore, silencing of these BRD4-occupied distal regulatory elements at the Pparg locus by CRISPRi demonstrates a critical role for these enhancers in the control of Pparg gene expression and adipogenesis in 3T3L1s. Together, these data establish BET bromodomain proteins as time- and context-dependent coactivators of the adipocyte cell state transition. PMID- 29444855 TI - Role of glutathione metabolism in host defense against Borrelia burgdorferi infection. AB - Pathogen-induced changes in host cell metabolism are known to be important for the immune response. In this study, we investigated how infection with the Lyme disease-causing bacterium Borrelia burgdorferi (Bb) affects host metabolic pathways and how these metabolic pathways may impact host defense. First, metabolome analysis was performed on human primary monocytes from healthy volunteers, stimulated for 24 h with Bb at low multiplicity of infection (MOI). Pathway analysis indicated that glutathione (GSH) metabolism was the pathway most significantly affected by Bb Specifically, intracellular levels of GSH increased on average 10-fold in response to Bb exposure. Furthermore, these changes were found to be specific, as they were not seen during stimulation with other pathogens. Next, metabolome analysis was performed on serum samples from patients with early-onset Lyme disease in comparison with patients with other infections. Supporting the in vitro analysis, we identified a cluster of GSH-related metabolites, the gamma-glutamyl amino acids, specifically altered in patients with Lyme disease, and not in other infections. Lastly, we performed in vitro experiments to validate the role for GSH metabolism in host response against Bb. We found that the GSH pathway is essential for Bb-induced cytokine production and identified glutathionylation as a potential mediating mechanism. Taken together, these data indicate a central role for the GSH pathway in the host response to Bb GSH metabolism and glutathionylation may therefore be important factors in the pathogenesis of Lyme disease and potentially other inflammatory diseases as well. PMID- 29444856 TI - Placental physiology monitored by hyperpolarized dynamic 13C magnetic resonance. AB - Placental functions, including transport and metabolism, play essential roles in pregnancy. This study assesses such processes in vivo, from a hyperpolarized MRI perspective. Hyperpolarized urea, bicarbonate, and pyruvate were administered to near-term pregnant rats, and all metabolites displayed distinctive behaviors. Little evidence of placental barrier crossing was observed for bicarbonate, at least within the timescales allowed by 13C relaxation. By contrast, urea was observed to cross the placental barrier, with signatures visible from certain fetal organs including the liver. This was further evidenced by the slower decay times observed for urea in placentas vis-a-vis other maternal compartments and validated by mass spectrometric analyses. A clear placental localization, as well as concurrent generation of hyperpolarized lactate, could also be detected for [1 13C]pyruvate. These metabolites also exhibited longer lifetimes in the placentas than in maternal arteries, consistent with a metabolic activity occurring past the trophoblastic interface. When extended to a model involving the administration of a preeclampsia-causing chemical, hyperpolarized MR revealed changes in urea's transport, as well as decreases in placental glycolysis vs. the naive animals. These distinct behaviors highlight the potential of hyperpolarized MR for the early, minimally invasive detection of aberrant placental metabolism. PMID- 29444857 TI - Doubly hybrid density functionals that correctly describe both density and energy for atoms. AB - Recently, it was argued [Medvedev MG, et al. (2017) Science 355:49-52] that the development of density functional approximations (DFAs) is "straying from the path toward the exact functional." The exact functional should yield both exact energy and density for a system of interest; nevertheless, they found that many heavily fitted functionals for molecular energies actually lead to poor electron densities of atoms. They also observed a trend that, for the nonempirical and few parameter functionals, densities can be improved as one climbs up the first four rungs of the Jacob's ladder of DFAs. The XYG3 type of doubly hybrid functionals (xDHs) represents a less-empirical and fewer-parameter functional on the top fifth rung, in which both the Hartree-Fock-like exchange and the second-order perturbative (MP2-like) correlation are hybridized with the low rung functionals. Here, we show that xDHs can well describe both density and energy for the same atomic set of Medvedev et al., showing that the latter trend can well be extended to the top fifth rung.

PMID- 29444860 TI - Humans quickly learn to blink strategically in response to environmental task demands. AB - Eye blinking is one of the most frequent human actions. The control of blinking is thought to reflect complex interactions between maintaining clear and healthy vision and influences tied to central dopaminergic functions including cognitive states, psychological factors, and medical conditions. The most imminent consequence of blinking is a temporary loss of vision. Minimizing this loss of information is a prominent explanation for changes in blink rates and temporarily suppressed blinks, but quantifying this loss is difficult, as environmental regularities are usually complex and unknown. Here we used a controlled detection experiment with parametrically generated event statistics to investigate human blinking control. Subjects were able to learn environmental regularities and adapted their blinking behavior strategically to better detect future events. Crucially, our design enabled us to develop a computational model that allows quantifying the consequence of blinking in terms of task performance. The model formalizes ideas from active perception by describing blinking in terms of optimal control in trading off intrinsic costs for blink suppression with task related costs for missing an event under perceptual uncertainty. Remarkably, this model not only is sufficient to reproduce key characteristics of the observed blinking behavior such as blink suppression and blink compensation but also predicts without further assumptions the well-known and diverse distributions of time intervals between blinks, for which an explanation has long been elusive.

AB - DNA methylation is an important epigenetic modification involved in gene regulation and transposable element silencing. Changes in DNA methylation can be heritable and, thus, can lead to the formation of stable epialleles. A well characterized example of a stable epiallele in plants is fwa, which consists of the loss of DNA cytosine methylation (5mC) in the promoter of the FLOWERING WAGENINGEN (FWA) gene, causing up-regulation of FWA and a heritable late flowering phenotype. Here we demonstrate that a fusion between the catalytic domain of the human demethylase TEN-ELEVEN TRANSLOCATION1 (TET1cd) and an artificial zinc finger (ZF) designed to target the FWA promoter can cause highly efficient targeted demethylation, FWA up-regulation, and a heritable late flowering phenotype. Additional ZF-TET1cd fusions designed to target methylated regions of the CACTA1 transposon also caused targeted demethylation and changes in expression. Finally, we have developed a CRISPR/dCas9-based targeted demethylation system using the TET1cd and a modified SunTag system. Similar to the ZF-TET1cd fusions, the SunTag-TET1cd system is able to target demethylation and activate gene expression when directed to the FWA or CACTA1 loci. Our study provides tools for targeted removal of 5mC at specific loci in the genome with high specificity and minimal off-target effects. These tools provide the opportunity to develop new epialleles for traits of interest, and to reactivate expression of previously silenced genes, transgenes, or transposons. PMID- 29444861 TI - Interacting-heads motif has been conserved as a mechanism of myosin II inhibition since before the origin of animals. AB - Electron microscope studies have shown that the switched-off state of myosin II in muscle involves intramolecular interaction between the two heads of myosin and between one head and the tail. The interaction, seen in both myosin filaments and isolated molecules, inhibits activity by blocking actin-binding and ATPase sites on myosin. This interacting-heads motif is highly conserved, occurring in invertebrates and vertebrates, in striated, smooth, and nonmuscle myosin IIs, and in myosins regulated by both Ca2+ binding and regulatory light-chain phosphorylation. Our goal was to determine how early this motif arose by studying the structure of inhibited myosin II molecules from primitive animals and from earlier, unicellular species that predate animals. Myosin II from Cnidaria (sea anemones, jellyfish), the most primitive animals with muscles, and Porifera (sponges), the most primitive of all animals (lacking muscle tissue) showed the same interacting-heads structure as myosins from higher animals, confirming the early origin of the motif. The social amoeba Dictyostelium discoideum showed a similar, but modified, version of the motif, while the amoeba Acanthamoeba castellanii and fission yeast (Schizosaccharomyces pombe) showed no head-head interaction, consistent with the different sequences and regulatory mechanisms of these myosins compared with animal myosin IIs. Our results suggest that head head/head-tail interactions have been conserved, with slight modifications, as a mechanism for regulating myosin II activity from the emergence of the first animals and before. The early origins of these interactions highlight their importance in generating the inhibited (relaxed) state of myosin in muscle and nonmuscle cells.

PMID- 29444864 TI - Lineage-specific gene acquisition or loss is involved in interspecific hybrid sterility in rice. AB - Understanding the genetic basis of reproductive barriers between species has been a central issue in evolutionary biology. The S1 locus in rice causes hybrid sterility and is a major reproductive barrier between two rice species, Oryza sativa and Oryza glaberrima The O. glaberrima-derived allele (denoted S1g) on the S1 locus causes preferential abortion of gametes with its allelic alternative (denoted S1s) in S1g/S1s heterozygotes. Here, we used mutagenesis and screening of fertile hybrid plants to isolate a mutant with an allele, S1mut, which does not confer sterility in the S1mut/S1g and S1mut/S1s hybrids. We found that the causal mutation of the S1mut allele was a deletion in the peptidase-coding gene (denoted "SSP") in the S1 locus of O. glaberrima No orthologous genes of SSP were found in the O. sativa genome. Transformation experiments indicated that the introduction of SSP in carriers of the S1s allele did not induce sterility. In S1mut/S1s heterozygotes, the insertion of SSP led to sterility, suggesting that SSP complemented the loss of the functional phenotype of the mutant and that multiple factors are involved in the phenomenon. The polymorphisms caused by the lineage-specific acquisition or loss of the SSP gene were implicated in the generation of hybrid sterility. Our results demonstrated that artificial disruption of a single gene for the reproductive barrier creates a "neutral" allele, which facilitates interspecific hybridization for breeding programs.

AB - The increasing resistance of human pathogens severely limits the efficacy of antibiotics in medicine, yet many animals, including solitary beewolf wasps, successfully engage in defensive alliances with antibiotic-producing bacteria for millions of years. Here, we report on the in situ production of 49 derivatives belonging to three antibiotic compound classes (45 piericidin derivatives, 3 streptochlorin derivatives, and nigericin) by the symbionts of 25 beewolf host species and subspecies, spanning 68 million years of evolution. Despite a high degree of qualitative stability in the antibiotic mixture, we found consistent quantitative differences between species and across geographic localities, presumably reflecting adaptations to combat local pathogen communities. Antimicrobial bioassays with the three main components and in silico predictions based on the structure and specificity in polyketide synthase domains of the piericidin biosynthesis gene cluster yield insights into the mechanistic basis and ecoevolutionary implications of producing a complex mixture of antimicrobial compounds in a natural setting.

AB - In multiple myeloma (MM), the bone marrow (BM) microenvironment may contain a myeloma cell fraction that has acquired treatment resistance by undergoing an epigenetic gene expression change. Hypoxic stress is an important factor in the BM microenvironment. Recently, we demonstrated that miR-210 was upregulated in hypoxia and downregulated IRF4, which is known as an essential factor in myeloma oncogenesis in normoxia. In the study, we demonstrated that myeloma cells still showed a strong antiapoptotic phenotype despite IRF4 downregulation, suggesting that another antiapoptotic factor might be involved under hypoxic stress. To determine the factor or factors, we conducted gene expression analysis on myeloma cells (primary samples and cell lines) that were exposed to chronic hypoxia and observed upregulation of glycolytic genes and genes encoding H3K9 demethylases in myeloma cells with hypoxia. Among these, KDM3A was most significantly upregulated in all examined cells, and its knockdown induced apoptosis of myeloma cells in chronic hypoxia. Expression of KDM3A was dependent on HIF-1alpha, which is a transcription factor specifically upregulated in hypoxia. We further demonstrated that an essential target of KDM3A was a noncoding gene, MALAT1, whose upregulation contributed to acquisition of an antiapoptotic phenotype by accumulation of HIF-1alpha, leading to upregulation of glycolytic genes under hypoxia. This process was independent from IRF4. These results led us to conclude that the hypoxia-inducible HIF-1alpha-KDM3A-MALAT1 axis also contributes to acquisition of the antiapoptotic phenotype via upregulation of glycolysis promoting genes. Thus, this axis is a promising therapeutic target against myeloma cells in the BM microenvironment. PMID- 29444875 TI - GP inspections: are sanctions holding back improvement in poor areas? PMID- 29444872 TI - FVIII proteins with a modified immunodominant T-cell epitope exhibit reduced immunogenicity and normal FVIII activity. AB - Factor VIII (FVIII)-neutralizing antibodies (inhibitors) are a serious complication in hemophilia A (HA). The peptide FVIII2194-2213 contains an immunodominant HLA-DRA*01-DRB1*01:01 (DRB1*01:01)-restricted epitope recognized by CD4+ T-effector cells from HA subjects. The aim of this study was to identify amino acid substitutions to deimmunize this epitope while retaining procoagulant function and expression levels comparable to those of wild-type (WT) FVIII proteins. The shortest DRB1*01:01-binding peptide was FVIII2194-2205, and residues important for affinity were identified as F2196, M2199, A2201, and S2204. T-cell proliferation experiments with Ala-substituted FVIII2194-2205 peptides identified F2196A as a substitution that abrogated proliferation of clones specific for the WT sequence. T-cell clones that were stimulated by recombinant WT-FVIII-C2 (rWT-FVIII-C2) protein did not proliferate when cultured with rFVIII-C2-F2196A, indicating the immunogenic peptide includes a naturally processed T-cell epitope. Additional amino acid substitutions at F2196 and M2199 were evaluated by peptide-MHC class II (MHCII)-binding assays, T-cell proliferation assays, epitope prediction algorithms, and sequence homologies. Six B-domain-deleted (BDD)-FVIII proteins with substitutions F2196A, F2196L, F2196K, M2199A, M2199W, or M2199R were produced. Proliferation of T-cell clones and polyclonal lines in response to rBDD-FVIII-F2196K and rBDD-FVIII-M2199A was reduced compared with responses to WT-BDD-FVIII. The BDD-FVIII-F2196K sequence modification appears to be the most promising sequence variant tested here, due to its effectiveness at eliminating DRB1*01:01-restricted immunogenicity, low potential immunogenicity in the context of other MHCII alleles, expression level comparable to WT-BDD-FVIII, and retained procoagulant activity. These results provide proof of principle for the design of less immunogenic FVIII proteins targeted to specific subsets of HA patients.

PMID- 29444881 TI - Ischaemic stroke, haemorrhage, and mortality in older patients with chronic kidney disease newly started on anticoagulation for atrial fibrillation: a population based study from UK primary care. AB - OBJECTIVE: To assess the association between anticoagulation, ischaemic stroke, gastrointestinal and cerebral haemorrhage, and all cause mortality in older people with atrial fibrillation and chronic kidney disease. DESIGN: Propensity matched, population based, retrospective cohort analysis from January 2006 through December 2016. SETTING: The Royal College of General Practitioners Research and Surveillance Centre database population of almost 2.73 million patients from 110 general practices across England and Wales. PARTICIPANTS: Patients aged 65 years and over with a new diagnosis of atrial fibrillation and estimated glomerular filtration rate (eGFR) of <50 mL/min/1.73m2, calculated using the chronic kidney disease epidemiology collaboration creatinine equation. Patients with a previous diagnosis of atrial fibrillation or receiving anticoagulation in the preceding 120 days were excluded, as were patients requiring dialysis and recipients of renal transplants. INTERVENTION: Receipt of an anticoagulant prescription within 60 days of atrial fibrillation diagnosis. MAIN OUTCOME MEASURES: Ischaemic stroke, cerebral or gastrointestinal haemorrhage, and all cause mortality. RESULTS: 6977 patients with chronic kidney disease and newly diagnosed atrial fibrillation were identified, of whom 2434 were on anticoagulants within 60 days of diagnosis and 4543 were not. 2434 pairs were matched using propensity scores by exposure to anticoagulant or none and followed for a median of 506 days. The crude rates for ischaemic stroke and haemorrhage were 4.6 and 1.2 after taking anticoagulants and 1.5 and 0.4 in patients who were not taking anticoagulant per 100 person years, respectively. The hazard ratios for ischaemic stroke, haemorrhage, and all cause mortality for those on anticoagulants were 2.60 (95% confidence interval 2.00 to 3.38), 2.42 (1.44 to 4.05), and 0.82 (0.74 to 0.91) compared with those who received no anticoagulation. CONCLUSION: Giving anticoagulants to older people with concomitant atrial fibrillation and chronic kidney disease was associated with an increased rate of ischaemic stroke and haemorrhage but a paradoxical lowered rate of all cause mortality. Careful consideration should be given before starting anticoagulants in older people with chronic kidney disease who develop atrial fibrillation. There remains an urgent need for adequately powered randomised trials in this population to explore these findings and to provide clarity on correct clinical management.

AB - AIMS: The cumulative effect of gestational diabetes mellitus (GDM) and hypertensive disorders of pregnancy (HDP) on postpartum cardio-metabolic diseases is equivocal. We aimed to assess the associations of GDM and HDP's individual and synergic contribution to risks of postpartum cardio-metabolic diseases (metabolic syndrome (MetS), abnormal glucose metabolism and hypertension (HTN)). METHODS: Of participants from a Singapore birth cohort, 276 mothers attending the 5-year postpartum visit were included in this study. During this visit, we collected mothers' history of GDM and HDP in all live births in a chronicle sequence and assessed the cardio-metabolic risks based on blood pressure, anthropometry and a panel of serum biomarkers. We diagnosed MetS, abnormal glucose metabolism and HTN according to Adult Treatment Panel III 2000 and World Health Organization guidelines. RESULTS: Of 276 mothers, 157 (56.9%) had histories of GDM while 23 (8.3%) had histories of HDP. After full adjustment, we found associations of GDM episodes with postpartum abnormal glucose metabolism (single episode: relative risk (RR) 2.9 (95% CI: 1.7, 4.8); recurrent episodes (>=2): RR = 3.8 (2.1-6.8)). Also, we found association between histories of HDP and HTN (RR = 3.6 (1.5, 8.6)). Having either (RR 2.6 (1.7-3.9)) or both gestational complications (RR 2.7 (1.6-4.9)) was associated with similar risk of postpartum cardio-metabolic disease. CONCLUSIONS: Mothers with GDM or HDP had a threefold increased risk of postpartum abnormal glucose metabolism or HTN, respectively. Having both GDM and HDP during past pregnancies was not associated with additional risk of postpartum cardio-metabolic diseases beyond that associated with either complication alone. PMID- 29444891 TI - Metabolic Syndrome Is Associated With Impaired Diastolic Function Independently of MRI-Derived Myocardial Extracellular Volume: The MESA Study. AB - The relationship of metabolic syndrome (MetS) and insulin resistance (one of its key pathophysiological mediators) with diastolic dysfunction and myocardial fibrosis is not well understood. This study aimed to evaluate the association of MetS with diastolic function and myocardial extracellular matrix (ECM) using cardiac MRI (CMRI) in a large community-based population. This cross-sectional analysis included 1,582 participants from the Multi-Ethnic Study of Atherosclerosis (MESA) with left ventricular ejection fraction >=50% and no history of cardiac events. Diastolic function was assessed using tagged CMRI parameters including end-diastolic strain rate (EDSR) and strain relaxation index (SRI). ECM was evaluated using extracellular volume (ECV) quantification. Participants' mean age was 67.4 +/- 8.6 years, and 48.1% were males. MetS was present in 533 individuals (33.7%), and type 2 diabetes in 250 (15.8%). In the multivariable analyses, MetS (irrespective of the presence of type 2 diabetes) and higher insulin resistance were associated with impaired diastolic function (higher SRI and lower EDSR), independent of ECV. In conclusion, MetS, irrespective of the presence of type 2 diabetes, was independently associated with impaired diastole. These functional myocardial changes seem to result from intrinsic cardiomyocyte alterations, irrespective of the myocardial interstitium (including fibrosis). PMID- 29444892 TI - Role of Protein Phosphatase 1 and Inhibitor of Protein Phosphatase 1 in Nitric Oxide-Dependent Inhibition of the DNA Damage Response in Pancreatic beta-Cells. AB - Nitric oxide is produced at micromolar levels by pancreatic beta-cells during exposure to proinflammatory cytokines. While classically viewed as damaging, nitric oxide also activates pathways that promote beta-cell survival. We have shown that nitric oxide, in a cell type-selective manner, inhibits the DNA damage response (DDR) and, in doing so, protects beta-cells from DNA damage-induced apoptosis. This study explores potential mechanisms by which nitric oxide inhibits DDR signaling. We show that inhibition of DDR signaling (measured by gammaH2AX formation and the phosphorylation of KAP1) is selective for nitric oxide, as other forms of reactive oxygen/nitrogen species do not impair DDR signaling. The kinetics and broad range of DDR substrates that are inhibited suggest that protein phosphatase activation may be one mechanism by which nitric oxide attenuates DDR signaling in beta-cells. While protein phosphatase 1 (PP1) is a primary regulator of DDR signaling and an inhibitor of PP1 (IPP1) is selectively expressed only in beta-cells, disruption of either IPP1 or PP1 does not modify the inhibitory actions of nitric oxide on DDR signaling in beta-cells. These findings support a PP1-independent mechanism by which nitric oxide selectively impairs DDR signaling and protects beta-cells from DNA damage-induced apoptosis. PMID- 29444893 TI - Dusp6 attenuates Ras/MAPK signaling to limit zebrafish heart regeneration. AB - Zebrafish regenerate cardiac tissue through proliferation of pre-existing cardiomyocytes and neovascularization. Secreted growth factors such as FGFs, IGF, PDGFs and Neuregulin play essential roles in stimulating cardiomyocyte proliferation. These factors activate the Ras/MAPK pathway, which is tightly controlled by the feedback attenuator Dual specificity phosphatase 6 (Dusp6), an ERK phosphatase. Here, we show that suppressing Dusp6 function enhances cardiac regeneration. Inactivation of Dusp6 by small molecules or by gene inactivation increased cardiomyocyte proliferation, coronary angiogenesis, and reduced fibrosis after ventricular resection. Inhibition of Erbb or PDGF receptor signaling suppressed cardiac regeneration in wild-type zebrafish, but had a milder effect on regeneration in dusp6 mutants. Moreover, in rat primary cardiomyocytes, NRG1-stimulated proliferation can be enhanced upon chemical inhibition of Dusp6 with BCI. Our results suggest that Dusp6 attenuates Ras/MAPK signaling during regeneration and that suppressing Dusp6 can enhance cardiac repair. PMID- 29444894 TI - Morphometrics of complex cell shapes: lobe contribution elliptic Fourier analysis (LOCO-EFA). AB - Quantifying cell morphology is fundamental to the statistical study of cell populations, and can help unravel mechanisms underlying cell and tissue morphogenesis. Current methods, however, require extensive human intervention, are highly parameter sensitive, or produce metrics that are difficult to interpret biologically. We therefore developed a method, lobe contribution elliptical Fourier analysis (LOCO-EFA), which generates from digitalised two dimensional cell outlines meaningful descriptors that can be directly matched to morphological features. This is shown by studying well-defined geometric shapes as well as actual biological cells from plant and animal tissues. LOCO-EFA provides a tool to phenotype efficiently and objectively populations of cells, here demonstrated by applying it to the complex shaped pavement cells of Arabidopsis thaliana wild-type and speechless leaves, and Drosophila amnioserosa cells. To validate our method's applicability to large populations, we analysed computer-generated tissues. By controlling in silico cell shape, we explored the potential impact of cell packing on individual cell shape, quantifying through LOCO-EFA deviations between the specified shape of single cells in isolation and the resultant shape when they interact within a confluent tissue. PMID- 29444895 TI - Optimizing Hybrid Closed-Loop Therapy in Adolescents and Emerging Adults Using the MiniMed 670G System. AB - OBJECTIVE: The MiniMed 670G System is the first commercial hybrid closed-loop (HCL) system for management of type 1 diabetes. Using data from adolescent and young adult participants, we compared insulin delivery patterns and time-in-range metrics in HCL (Auto Mode) and open loop (OL). System alerts, usage profiles, and operational parameters were examined to provide suggestions for optimal clinical use of the system. RESEARCH DESIGN AND METHODS: Data from 31 adolescent and young adult participants (14-26 years old) at three clinical sites in the 670G pivotal trial were analyzed. Participants had a 2-week run-in period in OL, followed by a 3-month in-home study phase with HCL functionality enabled. Data were compared between baseline OL and HCL use after 1 week, 1 month, 2 months, and 3 months. RESULTS: Carbohydrate-to-insulin (C-to-I) ratios were more aggressive for all meals with HCL compared with baseline OL. Total daily insulin dose and basal-to bolus ratio did not change during the trial. Time in range increased 14% with use of Auto Mode after 3 months (P < 0.001), and HbA1c decreased 0.75%. Auto Mode exits were primarily due to sensor/insulin delivery alerts and hyperglycemia. The percentage of time in Auto Mode gradually declined from 87%, with a final use rate of 72% (-15%). CONCLUSIONS: In transitioning young patients to the 670G system, providers should anticipate immediate C-to-I ratio adjustments while also assessing active insulin time. Users should anticipate occasional Auto Mode exits, which can be reduced by following system instructions and reliably bolusing for meals. Unique 670G system functionality requires ongoing clinical guidance and education from providers. PMID- 29444896 TI - Regulation of Hed1 and Rad54 binding during maturation of the meiosis-specific presynaptic complex. AB - Most eukaryotes have two Rad51/RecA family recombinases, Rad51, which promotes recombination during mitotic double-strand break (DSB) repair, and the meiosis specific recombinase Dmc1. During meiosis, the strand exchange activity of Rad51 is downregulated through interactions with the meiosis-specific protein Hed1, which helps ensure that strand exchange is driven by Dmc1 instead of Rad51. Hed1 acts by preventing Rad51 from interacting with Rad54, a cofactor required for promoting strand exchange during homologous recombination. However, we have a poor quantitative understanding of the regulatory interplay between these proteins. Here, we use real-time single-molecule imaging to probe how the Hed1- and Rad54-mediated regulatory network contributes to the identity of mitotic and meiotic presynaptic complexes. Based on our findings, we define a model in which kinetic competition between Hed1 and Rad54 helps define the functional identity of the presynaptic complex as cells undergo the transition from mitotic to meiotic repair. PMID- 29444897 TI - Role of NKp46+ natural killer cells in house dust mite-driven asthma. AB - House dust mite (HDM)-allergic asthma is driven by T helper 2 (Th2) lymphocytes, but also innate immune cells control key aspects of the disease. The precise function of innate natural killer (NK) cells during the initiation and propagation of asthma has been very confusing, in part because different, not entirely specific, strategies were used to target these cells. We show that HDM inhalation rapidly led to the accumulation of NK cells in the lung-draining lymph nodes and of activated CD69+ NK cells in the bronchoalveolar lumen. However, genetically engineered Ncr1-DTA or Ncr1-DTR mice that constitutively or temporarily lack NK cells, still developed all key features of acute or chronic HDM-driven asthma, such as bronchial hyperreactivity, Th2 cytokine production, eosinophilia, mucus overproduction, and Th2-dependent immunoglobulin serum titers. The same results were obtained by administration of conventional NK1.1 or asialo-GM1 NK cell-depleting antibodies, antibody-mediated blocking of the NKG2D receptor, or genetic NKG2D deficiency. Thus, although NK cells accumulate in allergen-challenged lungs, our findings comprehensively demonstrate that these cells are not required for HDM-driven asthma in the mouse. PMID- 29444898 TI - Significant prevalence of NR3C1 mutations in incidentally discovered bilateral adrenal hyperplasia: results of the French MUTA-GR Study. AB - BACKGROUND: Recently discovered mutations of NR3C1 gene, encoding for the GR, in patients with glucocorticoid resistance and bilateral adrenal incidentalomas prompted us to investigate whether GR mutations might be associated with adrenal hyperplasia. OBJECTIVE: The multicenter French Clinical Research Program (Muta GR) was set up to determine the prevalence of GR mutations and polymorphisms in patients harboring bilateral adrenal incidentalomas associated with hypertension and/or biological hypercortisolism without clinical Cushing's signs. RESULTS: One hundred patients were included in whom NR3C1 sequencing revealed five original heterozygous GR mutations that impaired GR signaling in vitro. Mutated patients presented with mild glucocorticoid resistance defined as elevated urinary free cortisol (1.7 +/- 0.7 vs 0.9 +/- 0.8 upper limit of normal range, P = 0.006), incomplete 1 mg dexamethasone suppression test without suppressed 8-AM adrenocorticotrophin levels (30.9 +/- 31.2 vs 16.2 +/- 17.5 pg/mL) compared to the non-mutated patients. Potassium and aldosterone levels were lower in mutated patients (3.6 +/- 0.2 vs 4.1 +/- 0.5 mmol/L, P = 0.01, and 17.3 +/- 9.9 vs 98.6 +/- 115.4 pg/mL, P = 0.0011, respectively) without elevated renin levels, consistent with pseudohypermineralocorticism. Ex vivo characterization of mutated patients' fibroblasts demonstrated GR haploinsufficiency as revealed by below normal glucocorticoid induction of FKBP5 gene expression. There was no association between GR polymorphisms and adrenal hyperplasia in this cohort, except an over-representation of BclI polymorphism. CONCLUSION: The 5% prevalence of heterozygous NR3C1 mutations discovered in our series is higher than initially thought and encourages GR mutation screening in patients with adrenal incidentalomas to unambiguously differentiate from Cushing's states and to optimize personalized follow-up. PMID- 29444899 TI - Comparison of Glasgow Admission Prediction Score and Amb Score in predicting need for inpatient care. AB - AIM: We compared the abilities of two established clinical scores to predict emergency department (ED) disposition: the Glasgow Admission Prediction Score (GAPS) and the Ambulatory Score (Ambs). METHODS: The scores were compared in a prospective, multicentre cohort study. We recruited consecutive patients attending ED triage at two UK sites: Northern General Hospital in Sheffield and Glasgow Royal Infirmary, between February and May 2016. Each had a GAPS and Ambs calculated at the time of triage, with the triage nurses and treating clinicians blinded to the scores. Patients were followed up to hospital discharge. The ability of the scores to discriminate discharge from ED and from hospital at 12 and 48 hours after arrival was compared using the area under the curve (AUC) of their receiving-operator characteristics (ROC). RESULTS: 1424 triage attendances were suitable for analysis during the study period, of which 567 (39.8%) were admitted. The AUC for predicting admission was significantly higher for GAPS at 0.807 (95% CI 0.785 to 0.830), compared with 0.743 (95% CI 0.717 to 0.769) for Ambs, P<0.00001. Similar results were seen when comparing ability to predict hospital stay of >12 hour and >48 hour. GAPS was also more accurate as a binary test, correctly predicting 1057 outcomes compared with 1004 for Ambs (74.2vs70.5%, P=0.012). CONCLUSION: The GAPS is a significantly better predictor of need for hospital admission than Ambs in an unselected ED population. PMID- 29444901 TI - Intensive Hemodialysis Fails to Reduce Plasma Levels of Uremic Solutes. PMID- 29444900 TI - Extended Duration Nocturnal Hemodialysis and Changes in Plasma Metabolite Profiles. AB - BACKGROUND AND OBJECTIVES: In-center, extended duration nocturnal hemodialysis has been associated with variable clinical benefits, but the effect of extended duration hemodialysis on many established uremic solutes and other components of the metabolome is unknown. We determined the magnitude of change in metabolite profiles for patients on extended duration nocturnal hemodialysis. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: In a 52-week prospective, observational study, we followed 33 patients receiving conventional thrice weekly hemodialysis who converted to nocturnal hemodialysis (7-8 hours per session, three times per week). A separate group of 20 patients who remained on conventional hemodialysis (3-4 hours per session, three times per week) served as a control group. For both groups, we applied liquid chromatography-mass spectrometry-based metabolite profiling on stored plasma samples collected from all participants at baseline and after 1 year. We examined longitudinal changes in 164 metabolites among those who remained on conventional hemodialysis and those who converted to nocturnal hemodialysis using Wilcoxon rank sum tests adjusted for multiple comparisons (false discovery rate <0.05). RESULTS: On average, the nocturnal group had 9.6 hours more dialysis per week than the conventional group. Among 164 metabolites, none changed significantly from baseline to study end in the conventional group. Twenty-nine metabolites changed in the nocturnal group, 21 of which increased from baseline to study end (including all branched-chain amino acids). Eight metabolites decreased after conversion to nocturnal dialysis, including l carnitine and acetylcarnitine. By contrast, several established uremic retention solutes, including p-cresol sulfate, indoxyl sulfate, and trimethylamine N-oxide, did not change with extended dialysis. CONCLUSIONS: Across a wide array of metabolites examined, extended duration hemodialysis was associated with modest changes in the plasma metabolome, with most differences relating to metabolite increases, despite increased dialysis time. Few metabolites showed reduction with more dialysis, and no change in several established uremic toxins was observed. PMID- 29444902 TI - The Effect of Single Mismatches on Primer Extension. AB - BACKGROUND: Allele-specific PCR is an important diagnostic tool that identifies single-nucleotide variants by preferential amplification of a particular allele, using primers that are mismatched to all but one allele variant. METHODS: We applied a fluorescent stopped-flow polymerase assay to measure extension rates from oligonucleotide hairpins to simulate primer-template pairs. Under PCR applicable conditions, reaction rates were recorded in nucleotides per second per polymerase (nt/s/poly). The effects of temperature, potassium chloride, mismatch type, and position were studied with primarily a deletion mutant of Thermus aquaticus (Taq) DNA polymerase and 135 oligonucleotide sequences. RESULTS: Rates at 65 degrees C were between 205 +/- 11 and 177 +/- 8 nt/s/poly for matched templates and between 4.55 +/- 0.21 and 0.008 +/- 0.005 nt/s/poly for 3' mismatched templates. Although extension rates progressively increased with mismatches further away from the 3' end, rates were still reduced by as much as 84% with a C . C mismatch 6 bases from the 3' end. The optimal extension temperature for matched sequences was 70 degrees C, shifting to 55-60 degrees C for 3' mismatches. KCl inhibited mismatch extension. The Michaelis constant (Km) was increased and the apparent unimolecular rate constant (kcat) decreased for 3' mismatches relative to matched templates. CONCLUSIONS: Although primer extension of mismatches depends on mismatch type and position, variation also depends on local sequence, KCl concentration, and the type of polymerase. Introduction of 3' mismatches reduces the optimal temperature for extension, suggesting higher annealing temperatures for better allele discrimination. Quantitative descriptions of expected specificity in allele-specific PCR provide additional design direction and suggest when other methods (e.g., high-resolution melting analysis) may be a better choice. PMID- 29444903 TI - Generation and Characterization of a CYP2C11-Null Rat Model by Using the CRISPR/Cas9 Method. AB - CYP2C11 is involved in the metabolism of many drugs in rats. To assess the roles of CYP2C11 in physiology and drug metabolism, a CYP2C11-null rat model was generated using the clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9method. A 2-base pair insertion was added to exon 6 of CYP2C11 in Sprague-Dawley rats. CYP2C11 was not detected by western blotting in liver microsomes of CYP2C11-null rats. No off-target effects were found at 11 predicted sites of the knockout model. The CYP2C11-null rats were viable and had no obvious abnormalities, with the exception of reduced fertility. Puberty in CYP2C11-null rats appeared to be delayed by ~20 days, and the average litter size fell by 43%. Tolbutamide was used as a probe in this drug metabolism study. In the liver microsomes of CYP2C11-null rats, the Vmax and intrinsicclearance values decreased by 22% and 47%, respectively, compared with those of wild-type rats. The Km values increased by 47% compared with that of wild types. However, our pharmacokinetics study showed no major differences in any parameters between the two strains, in both males and females. In conclusion, a CYP2C11-null rat model was successfully generated and is a valuable tool to study the in vivo function of CYP2C11. PMID- 29444904 TI - Mutation in an alternative transcript of CDKL5 in a boy with early-onset seizures. AB - Infantile-onset epilepsies are a set of severe, heterogeneous disorders for which clinical genetic testing yields causative mutations in ~20%-50% of affected individuals. We report the case of a boy presenting with intractable seizures at 2 wk of age, for whom gene panel testing was unrevealing. Research-based whole genome sequencing of the proband and four unaffected family members identified a de novo mutation, NM_001323289.1:c.2828_2829delGA in CDKL5, a gene associated with X-linked early infantile epileptic encephalopathy 2. CDKL5 has multiple alternative transcripts, and the mutation lies in an exon in the brain-expressed forms. The mutation was undetected by gene panel sequencing because of its intronic location in the CDKL5 transcript typically used to define the exons of this gene for clinical exon-based tests (NM_003159). This is the first report of a patient with a mutation in an alternative transcript of CDKL5 This finding suggests that incorporating alternative transcripts into the design and variant interpretation of exon-based tests, including gene panel and exome sequencing, could improve the diagnostic yield. PMID- 29444906 TI - Detection of myositis-specific antibodies: additional notes. PMID- 29444905 TI - Renal Interstitial Platelet-Derived Growth Factor Receptor-beta Cells Support Proximal Tubular Regeneration. AB - BACKGROUND: The kidney is considered to be a structurally stable organ with limited baseline cellular turnover. Nevertheless, single cells must be constantly replaced to conserve the functional integrity of the organ. PDGF chain B (PDGF BB) signaling through fibroblast PDGF receptor-beta (PDGFRbeta) contributes to interstitial-epithelial cell communication and facilitates regenerative functions in several organs. However, the potential role of interstitial cells in renal tubular regeneration has not been examined. METHODS: In mice with fluorescent protein expression in renal tubular cells and PDGFRbeta-positive interstitial cells, we ablated single tubular cells by high laser exposure. We then used serial intravital multiphoton microscopy with subsequent three-dimensional reconstruction and ex vivo histology to evaluate the cellular and molecular processes involved in tubular regeneration. RESULTS: Single-tubular cell ablation caused the migration and division of dedifferentiated tubular epithelial cells that preceded tubular regeneration. Moreover, tubular cell ablation caused immediate calcium responses in adjacent PDGFRbeta-positive interstitial cells and the rapid migration thereof toward the injury. These PDGFRbeta-positive cells enclosed the injured epithelium before the onset of tubular cell dedifferentiation, and the later withdrawal of these PDGFRbeta-positive cells correlated with signs of tubular cell redifferentiation. Intraperitoneal administration of trapidil to block PDGFRbeta impeded PDGFRbeta-positive cell migration to the tubular injury site and compromised the recovery of tubular function. CONCLUSIONS: Ablated tubular cells are exclusively replaced by resident tubular cell proliferation in a process dependent on PDGFRbeta-mediated communication between the renal interstitium and the tubular system.

This study examined small airway pathology using a novel combination of multidetector row computed tomography (MDCT), micro computed tomography (microCT) and histology.Airway branches visible on specimen MDCT were counted and the dimensions of the third- to fifth-generation airways were computed, while the terminal bronchioles (designated TB), preterminal bronchioles (TB-1) and pre-preterminal bronchioles (TB-2) were examined with microCT and histology in eight explanted lungs with end-stage COPD and seven unused donor lungs that served as controls.On MDCT, COPD lungs showed a decrease in the number of 2-2.5 mm diameter airways and the lumen area of fifth-generation airways, while on microCT there was a reduction in the number of terminal bronchioles as well as a decrease in the luminal areas, wall volumes and alveolar attachments to the walls of TB, TB-1 and TB-2 bronchioles. The combination of microCT and histology showed increased B-cell infiltration into the walls of TB-1 and TB-2 bronchioles, and this change was correlated with a reduced number of alveolar attachments in COPD.Small airways disease extends from 2 mm diameter airways to the terminal bronchioles in COPD. Destruction of alveolar attachments may be driven by a B-cell-mediated immune response in the preterminal bronchioles.

AB - Experimental models of neuroendocrine tumour disease are scarce, and no comprehensive characterisation of existing gastroenteropancreatic neuroendocrine tumour (GEPNET) cell lines has been reported. In this study, we aimed to define the molecular characteristics and therapeutic sensitivity of these cell lines. We therefore performed immunophenotyping, copy number profiling, whole-exome sequencing and a large-scale inhibitor screening of seven GEPNET cell lines. Four cell lines, GOT1, P-STS, BON-1 and QGP-1, displayed a neuroendocrine phenotype while three others, KRJ-I, L-STS and H-STS, did not. Instead, these three cell lines were identified as lymphoblastoid. Characterisation of remaining authentic GEPNET cell lines by copy number profiling showed that GOT1, among other chromosomal alterations, harboured losses on chromosome 18 encompassing the SMAD4 gene, while P-STS had a loss on 11q. BON-1 had a homozygous loss of CDKN2A and CDKN2B, and QGP-1 harboured amplifications of MDM2 and HMGA2 Whole-exome sequencing revealed both disease-characteristic mutations (e.g. ATRX mutation in QGP-1) and, for patient tumours, rare genetic events (e.g. TP53 mutation in P STS, BON-1 and QGP-1). A large-scale inhibitor screening showed that cell lines from pancreatic NETs to a greater extent, when compared to small intestinal NETs, were sensitive to inhibitors of MEK. Similarly, neuroendocrine NET cells originating from the small intestine were considerably more sensitive to a group of HDAC inhibitors. Taken together, our results provide a comprehensive characterisation of GEPNET cell lines, demonstrate their relevance as neuroendocrine tumour models and explore their therapeutic sensitivity to a broad range of inhibitors. PMID- 29444913 TI - Lung transplantation after allogeneic stem cell transplantation: a pan-European experience. AB - Late-onset noninfectious pulmonary complications (LONIPCs) affect 6% of allogeneic stem cell transplantation (SCT) recipients within 5 years, conferring subsequent 5-year survival of 50%. Lung transplantation is rarely performed in this setting due to concomitant extrapulmonary morbidity, excessive immunosuppression and concerns about recurring malignancy being considered contraindications. This study assesses survival in highly selected patients undergoing lung transplantation for LONIPCs after SCT.SCT patients undergoing lung transplantation at 20 European centres between 1996 and 2014 were included. Clinical data pre- and post-lung transplantation were reviewed. Propensity score matched controls were generated from the Eurotransplant and Scandiatransplant registries. Kaplan-Meier survival analysis and Cox proportional hazard regression models evaluating predictors of graft loss were performed.Graft survival at 1, 3 and 5 years of 84%, 72% and 67%, respectively, among the 105 SCT patients proved comparable to controls (p=0.75). Sepsis accounted for 15 out of 37 deaths (41%), with prior mechanical ventilation (HR 6.9, 95% CI 1.0-46.7; p<0.001) the leading risk factor. No SCT-specific risk factors were identified. Recurring malignancy occurred in four patients (4%). Lung transplantation <2 years post-SCT increased all-cause 1-year mortality (HR 7.5, 95% CI 2.3-23.8; p=0.001).Lung transplantation outcomes following SCT were comparable to other end-stage diseases. Lung transplantation should be considered feasible in selected candidates. No SCT-specific factors influencing outcome were identified within this carefully selected patient cohort. PMID- 29444915 TI - Predictors of accelerated decline in lung function in adult-onset asthma. AB - Little is known about the prognosis of adults with new-onset asthma. Cross sectional studies suggest that these patients may exhibit accelerated decline in forced expiratory volume in 1 s (FEV1). However, risk factors for accelerated decline in lung function have not yet been identified.We aimed to identify these risk factors in a prospective 5-year follow-up study in 200 adults with newly diagnosed asthma. In the current study, clinical, functional and inflammatory parameters were assessed annually for 5 years. Linear mixed-effects models were used to identify predictors.Evaluable lung function sets of 141 patients were available. Median (interquartile range) change in post-bronchodilator FEV1 was 17.5 (-54.2 to +22.4) mL per year. Accelerated decline in FEV1 was defined by the lower quartile of decline (>54.2 mL per year). Nasal polyps, number of blood and sputum eosinophils, body mass index, and level of exhaled nitric oxide were univariably associated with decline in lung function. Only the latter two were independently associated. Using cut-off values to identify patients at highest risk showed accelerated decline in FEV1 in all patients with combined exhaled nitric oxide fraction (FeNO) >=57 ppb and body mass index (BMI) <=23 kg.m-2We conclude that adults with new-onset asthma with both high levels of exhaled nitric oxide and low BMI are at risk of accelerated decline in lung function. PMID- 29444914 TI - Palatal prolapse as a signature of expiratory flow limitation and inspiratory palatal collapse in patients with obstructive sleep apnoea. AB - In some individuals with obstructive sleep apnoea (OSA), the palate prolapses into the velopharynx during expiration, limiting airflow through the nose or shunting it out of the mouth. We hypothesised that this phenomenon causes expiratory flow limitation (EFL) and is associated with inspiratory "isolated" palatal collapse. We also wanted to provide a robust noninvasive means to identify this mechanism of obstruction.Using natural sleep endoscopy, 1211 breaths from 22 OSA patients were scored as having or not having palatal prolapse. The patient-level site of collapse (tongue-related, isolated palate, pharyngeal lateral walls and epiglottis) was also characterised. EFL was quantified using expiratory resistance at maximal epiglottic pressure. A noninvasive EFL index (EFLI) was developed to detect the presence of palatal prolapse and EFL using the flow signal alone. In addition, the validity of using nasal pressure was assessed.A cut-off value of EFLI >0.8 detected the presence of palatal prolapse and EFL with an accuracy of >95% and 82%, respectively. The proportion of breaths with palatal prolapse predicted isolated inspiratory palatal collapse with 90% accuracy.This study demonstrates that expiratory palatal prolapse can be quantified noninvasively, is associated with EFL and predicts the presence of inspiratory isolated palatal collapse. PMID- 29444916 TI - Low uptake of palliative care for COPD patients within primary care in the UK. AB - Mortality and symptom burden from chronic obstructive pulmonary disease (COPD) and lung cancer are similar but there is thought to be an inequality in palliative care support (PCS) between diseases. This nationally representative study assessed PCS for COPD patients within primary care in the UK.This was a cohort study using electronic healthcare records (2004-2015). Factors associated with receiving PCS were assessed using logistic regression for the whole cohort and deceased patients.There were 92 365 eligible COPD patients, of which 26 135 died. Only 7.8% of the whole cohort and 21.4% of deceased patients received PCS. Lung cancer had a strong association with PCS compared with other patient characteristics, including Global Initiative for Chronic Obstructive Lung Disease stage and Medical Research Council Dyspnoea score (whole cohort, lung cancer: OR 14.1, 95% CI 13.1-15; deceased patients, lung cancer: OR 6.5, 95% CI 6-7). Only 16.7% of deceased COPD patients without lung cancer received PCS compared with 56.5% of deceased patients with lung cancer. In patients that received PCS, lung cancer co-diagnosis significantly increased the chances of receiving PCS before the last month of life (1-6 versus <=1 month pre-death: risk ratio 1.4, 95% CI 1.3-1.7).Provision of PCS for COPD patients in the UK is inadequate. Lung cancer, not COPD, was the dominant driver for COPD patients to receive PCS. PMID- 29444918 TI - Immunotherapy: a new standard of care in thoracic malignancies? A summary of the European Respiratory Society research seminar of the Thoracic Oncology Assembly. AB - In May 2017, the second European Respiratory Society research seminar of the Thoracic Oncology Assembly entitled "Immunotherapy, a new standard of care in thoracic malignancies?" was held in Paris, France. This seminar provided an opportunity to review the basis of antitumour immunity and to explain how immune checkpoint inhibitors (ICIs) work. The main therapeutic trials that have resulted in marketing authorisations for use of ICIs in lung cancer were reported. A particular focus was on the toxicity of these new molecules in relation to their immune-related adverse events. The need for biological selection, currently based on immunohistochemistry testing to identify the tumour expression of programmed death ligand (PD-L)1, was stressed, as well as the need to harmonise PD-L1 testing and techniques. Finally, sessions were dedicated to the combination of ICIs and radiotherapy and the place of ICIs in nonsmall cell lung cancer with oncogenic addictions. Finally, an important presentation was dedicated to the future of antitumour vaccination and of all ongoing trials in thoracic oncology.

AB - Tracheal reconstruction is one of the greatest challenges in thoracic surgery when direct end-to-end anastomosis is impossible or after this procedure has failed. The main indications for tracheal reconstruction include malignant tumours (squamous cell carcinoma, adenoid cystic carcinoma), tracheoesophageal fistula, trauma, unsuccessful surgical results for benign diseases and congenital stenosis. Tracheal substitutes can be classified into five types: 1) synthetic prosthesis; 2) allografts; 3) tracheal transplantation; 4) tissue engineering; and 5) autologous tissue composite. The ideal tracheal substitute is still unclear, but some techniques have shown promising clinical results. This article reviews the advantages and limitations of each technique used over the past few decades in clinical practice. The main limitation seems to be the capacity for tracheal tissue regeneration. The physiopathology behind this has yet to be fully understood. Research on stem cells sparked much interest and was thought to be a revolutionary technique; however, the poor long-term results of this approach highlight that there is a long way to go in this research field. Currently, an autologous tissue composite, with or without a tracheal allograft, is the only long-term working solution for every aetiology, despite its technical complexity and setbacks.

PMID- 29444925 TI - Increasing Incidence and Prevalence of World Health Organization Groups 1 to 4 Pulmonary Hypertension: A Population-Based Cohort Study in Ontario, Canada. AB - BACKGROUND: The World Health Organization recognizes 5 groups of pulmonary hypertension (PH), categorized by pathogenesis or comorbidity: 1-pulmonary arterial hypertension 2-left-heart disease, 3-lung disease and hypoxia 4-chronic thromboembolic disease, and 5-miscellaneous. The epidemiology of PH, apart from group 1, is largely unknown. METHODS AND RESULTS: We describe incidence, prevalence, comorbidities, mortality and prescribing patterns for groups 1 to 4 PH from 1993 to 2012. Case definitions are based on hospitalizations and emergency department visits, using the Institute for Clinical Evaluative Sciences data, which comprises linked databases of universal coverage health service records for Ontario residents. This cohort included 50 529 patients with PH. The annual incidence of adult PH increased from 2003 to 2012 from 24.1 to 28.7 cases/100 000 population and the annual prevalence from 1993 to 2012 from 99.8 to 127.3 cases/100 000 population, respectively. The most common form of adult PH was group 2, alone (34.2%) or combined with group 3 PH (29.3%). A diagnosis of PH increased the 1-year standardized mortality ratio 7.2-fold. Mortality in adults with PH was 13.0%, 36.4%, and 62.4%, at 30 days, 1 year, and 5 years, respectively. Mortality was highest in groups 2 and 3 and lowest in group 1. PH was present in only 3.6% of people with left heart disease, 0.7% with lung disease, and 1.4% with thromboembolic disease, suggesting that PH is a relatively rare complication of these common diseases. Children (age<16 years) accounted for 3.6% of the cohort. In children group 1 PH was most common (65.2%), and 5-year mortality was lower (21.4%) than in adults. Group 1-specific PH therapies were increasingly prescribed over time and paradoxically were often used in patients who seemed to have group 2, PH based on diagnostic codes indicating left heart disease. CONCLUSIONS: The incidence and prevalence of adult PH are increasing. Groups 2 and 3 are the most common and lethal forms of PH. This study identifies an emerging epidemic of PH that likely has substantial adverse health and economic implications.

PMID- 29444926 TI - High-Sensitivity Cardiac Troponin I and the Diagnosis of Coronary Artery Disease in Patients With Suspected Angina Pectoris. AB - BACKGROUND: We determined whether high-sensitivity cardiac troponin I can improve the estimation of the pretest probability for obstructive coronary artery disease (CAD) in patients with suspected stable angina. METHODS AND RESULTS: In a prespecified substudy of the SCOT-HEART trial (Scottish Computed Tomography of the Heart), plasma cardiac troponin was measured using a high-sensitivity single molecule counting assay in 943 adults with suspected stable angina who had undergone coronary computed tomographic angiography. Rates of obstructive CAD were compared with the pretest probability determined by the CAD Consortium risk model with and without cardiac troponin concentrations. External validation was undertaken in an independent study population from Denmark comprising 487 patients with suspected stable angina. Higher cardiac troponin concentrations were associated with obstructive CAD with a 5-fold increase across quintiles (9% 48%; P<0.001) independent of known cardiovascular risk factors (odds ratio, 1.35; 95% confidence interval, 1.25-1.46 per doubling of troponin). Cardiac troponin concentrations improved the discrimination and calibration of the CAD Consortium model for identifying obstructive CAD (C statistic, 0.788-0.800; P=0.004; chi2=16.8 [P=0.032] to 14.3 [P=0.074]). The updated model also improved classification of the American College of Cardiology/American Heart Association pretest probability risk categories (net reclassification improvement, 0.062; 95% confidence interval, 0.035-0.089). The revised model achieved similar improvements in discrimination and calibration when applied in the external validation cohort. CONCLUSIONS: High-sensitivity cardiac troponin I concentration is an independent predictor of obstructive CAD in patients with suspected stable angina. Use of this test may improve the selection of patients for further investigation and treatment. CLINICAL TRIAL REGISTRATION: URL: https://www.clinicaltrials.gov. Unique identifier: NCT01149590. PMID- 29444929 TI - Development and External Validation of Prediction Models for 10-Year Survival of Invasive Breast Cancer. Comparison with PREDICT and CancerMath. AB - Purpose: To compare PREDICT and CancerMath, two widely used prognostic models for invasive breast cancer, taking into account their clinical utility. Furthermore, it is unclear whether these models could be improved.Experimental Design: A dataset of 5,729 women was used for model development. A Bayesian variable selection algorithm was implemented to stochastically search for important interaction terms among the predictors. The derived models were then compared in three independent datasets (n = 5,534). We examined calibration, discrimination, and performed decision curve analysis.Results: CancerMath demonstrated worse calibration performance compared with PREDICT in estrogen receptor (ER)-positive and ER-negative tumors. The decline in discrimination performance was -4.27% ( 6.39 to -2.03) and -3.21% (-5.9 to -0.48) for ER-positive and ER-negative tumors, respectively. Our new models matched the performance of PREDICT in terms of calibration and discrimination, but offered no improvement. Decision curve analysis showed predictions for all models were clinically useful for treatment decisions made at risk thresholds between 5% and 55% for ER-positive tumors and at thresholds of 15% to 60% for ER-negative tumors. Within these threshold ranges, CancerMath provided the lowest clinical utility among all the models.Conclusions: Survival probabilities from PREDICT offer both improved accuracy and discrimination over CancerMath. Using PREDICT to make treatment decisions offers greater clinical utility than CancerMath over a range of risk thresholds. Our new models performed as well as PREDICT, but no better, suggesting that, in this setting, including further interaction terms offers no predictive benefit. Clin Cancer Res; 24(9); 2110-5.

AB - Purpose: Immunotherapeutic treatment strategies for glioblastoma (GBM) are under investigation in clinical trials. However, our understanding of the immune phenotype of GBM-infiltrating T cells (tumor-infiltrating lymphocytes; TILs) and changes during disease progression is limited. Deeper insight is urgently needed to therapeutically overcome tumor-induced immune exhaustion.Experimental Design: We used flow cytometry and cytokine assays to profile TILs and peripheral blood lymphocytes (PBLs) from patients with GBM, comparing newly diagnosed or recurrent GBM to long-term survivors (LTS) and healthy donors. TCR sequencing was performed on paired samples of newly diagnosed and recurrent GBM.Results: We identified a clear immune signature of exhaustion and clonal restriction in the TILs of patients with GBM. Exhaustion of CD8+ TILs was defined by an increased prevalence of PD-1+, CD39+, Tim-3+, CD45RO+, HLA-DR+ marker expression, and exhibition of an effector-/transitional memory differentiation phenotype, whereas KLRG1 and CD57 were underrepresented. Immune signatures were similar in primary and recurrent tumors; however, restricted TCR repertoire clonality and a more activated memory phenotype were observed in TILs from recurrent tumors. Moreover, a reduced cytokine response to PHA stimulation in the blood compartment indicates a dysfunctional peripheral T-cell response in patients with GBM. LTS displayed a distinct profile, with abundant naive and less exhausted CD8+ T cells.Conclusions: TILs and PBLs exhibit contrasting immune profiles, with a distinct exhaustion signature present in TILs. While the exhaustion profiles of primary and recurrent GBM are comparable, TCR sequencing demonstrated a contracted repertoire in recurrent GBM, concomitant with an increased frequency of activated memory T cells in recurrent tumors.

PMID- 29444931 TI - Complete Remission with Reduction of High-Risk Clones following Haploidentical NK Cell Therapy against MDS and AML. AB - Purpose: To evaluate the safety, efficacy, and immunobiological correlates of allogeneic NK-cell-based therapy in primary chemotherapy-refractory or relapsed high-risk myelodysplastic syndrome (MDS), secondary AML (MDS/AML), and de novo AML patients.Experimental Design: Sixteen patients received fludarabine/cyclophosphamide conditioning combined with total lymphoid irradiation followed by adoptive immunotherapy with IL2-activated haploidentical NK cells.Results: NK-cell infusions were well-tolerated, with only transient adverse events observed in the 16 patients. Six patients achieved objective responses with complete remission (CR), marrow CR, or partial remission (PR). Five patients proceeded to allogeneic hematopoietic stem cell transplantation (HSCT). Three patients are still free from disease >3 years after treatment. All evaluable patients with objective responses (5/5 evaluable) had detectable donor NK cells at days 7/14 following infusion and displayed reduction of tumor cell clones, some of which carried poor prognosis mutations. Residual lin CD34+CD123+CD45RA+ blast cells in responders had increased total HLA class I and HLA-E expression. Responding patients displayed less pronounced activation of CD8+ T cells and lower levels of inflammatory cytokines following NK-cell infusion. Intriguingly, despite omission of systemic IL2, all patients displayed increased frequencies of activated Ki-67+CD127-FoxP3+CD25hiCD4+ Treg cells of recipient origin following NK-cell therapy.Conclusions: Overall, this study suggests that high-risk MDS is responsive to NK-cell therapy and supports the use of haploidentical NK-cell infusions as a bridge to HSCT in refractory patients. Objective clinical responses and reduction of high-risk clones were associated with detectable donor-derived NK cells, immunoediting of residual blast cells, and less pronounced host immune activation.

PMID- 29444933 TI - PNLDC1, mouse pre-piRNA Trimmer, is required for meiotic and post-meiotic male germ cell development. AB - PIWI-interacting RNAs (piRNAs) are germ cell-specific small RNAs essential for retrotransposon gene silencing and male germ cell development. In piRNA biogenesis, the endonuclease MitoPLD/Zucchini cleaves long, single-stranded RNAs to generate 5' termini of precursor piRNAs (pre-piRNAs) that are consecutively loaded into PIWI-family proteins. Subsequently, these pre-piRNAs are trimmed at their 3'-end by an exonuclease called Trimmer. Recently, poly(A)-specific ribonuclease-like domain-containing 1 (PNLDC1) was identified as the pre-piRNA Trimmer in silkworms. However, the function of PNLDC1 in other species remains unknown. Here, we generate Pnldc1 mutant mice and analyze small RNAs in their testes. Our results demonstrate that mouse PNLDC1 functions in the trimming of both embryonic and post-natal pre-piRNAs. In addition, piRNA trimming defects in embryonic and post-natal testes cause impaired DNA methylation and reduced MIWI expression, respectively. Phenotypically, both meiotic and post-meiotic arrests are evident in the same individual Pnldc1 mutant mouse. The former and latter phenotypes are similar to those of MILI and MIWI mutant mice, respectively. Thus, PNLDC1-mediated piRNA trimming is indispensable for the function of piRNAs throughout mouse spermatogenesis. PMID- 29444934 TI - Bromofatty aldehyde derived from bromine exposure and myeloperoxidase and eosinophil peroxidase modify GSH and protein. AB - alpha-Chlorofatty aldehydes (alpha-ClFALDs) and alpha-bromofatty aldehydes (alpha BrFALDs) are produced in activated neutrophils and eosinophils. This study investigated the ability of alpha-BrFALD and alpha-ClFALD to react with the thiols of GSH and protein cysteinyl residues. Initial studies showed that 2 bromohexadecanal (2-BrHDA) and 2-chlorohexadecanal (2-ClHDA) react with GSH producing the same fatty aldehyde-GSH adduct (FALD-GSH). In both synthetic and cellular reactions, FALD-GSH production was more robust with 2-BrHDA compared with 2-ClHDA as precursor. NaBr-supplemented phorbol myristate acetate (PMA) activated neutrophils formed more alpha-BrFALD and FALD-GSH compared with non NaBr-supplemented neutrophils. Primary human eosinophils, which preferentially produce hypobromous acid and alpha-BrFALD, accumulated FALD-GSH following PMA stimulation. Mice exposed to Br2 gas had increased levels of both alpha-BrFALD and FALD-GSH in the lungs, as well as elevated systemic plasma levels of FALD-GSH in comparison to mice exposed to air. Similar relative reactivity of alpha-ClFALD and alpha-BrFALD with protein thiols was shown using click analogs of these aldehydes. Collectively, these data demonstrate that GSH and protein adduct formation are much greater as a result of nucleophilic attack of cysteinyl residues on alpha-BrFALD compared with alpha-ClFALD, which was observed in both primary leukocytes and in mice exposed to bromine gas. PMID- 29444935 TI - Adenylyl cyclase 1 as a major isoform to generate cAMP signaling for apoA-1 mediated cholesterol efflux pathway. AB - HDL apoA-1-mediated cholesterol efflux pathway requires multiple cellular proteins and signal transduction processes, including adenylyl cyclase (AC)/cAMP signaling. Due to the existence of multiple transmembrane AC isoforms, it was not known how many AC isoforms are expressed and which ones are essential for cholesterol efflux in macrophage foam cells. These questions were investigated in THP-1 macrophages in this study. Quantitative RT-PCR detected mRNAs for all nine transmembrane AC isoforms, but only the mRNA and protein of the AC1 isoform were consistently upregulated by cholesterol loading and apoA-1. AC1 shRNA interference decreased AC1 mRNA and protein levels, resulting in reduction of apoA-1-mediated cAMP production and cholesterol efflux, while the intracellular cholesterol levels remained high. Confocal microscopy showed that apoA-1 promoted translocation of cholesterol and formation of cholesterol-apoA-1 complexes (protrusions) on the cholesterol-loaded macrophage surface. AC1 shRNA-interfered macrophages showed no translocation of cholesterol to the cell surface. AC1 shRNA interference also disrupted cellular localization of the intracellular cholesterol indicator protein adipophillin, and the expression as well as surface translocation of ABCA1. Together, our results show that AC1 is a major isoform for apoA-1-activated cAMP signaling to promote cholesterol transport and exocytosis to the surface of THP-1 macrophage foam cells. PMID- 29444936 TI - Aspirin alone and combined with a statin suppresses eicosanoid formation in human colon tissue. AB - Eicosanoids, including prostaglandins (PGs) and thromboxanes, are broadly bioactive lipid mediators and increase colon tumorigenesis possibly through chronic inflammatory mechanisms. Epidemiological and experimental data suggest that acetylsalicylic acid (ASA) helps prevent colorectal cancer (CRC), possibly through cyclooxygenase (COX)-mediated suppression of eicosanoid, particularly PGE2, formation. Recent studies suggest that statins prevent CRC and improve survival after diagnosis. We identified patients on ASA and/or statin treatment undergoing routine colonoscopy and measured eicosanoid levels in colonic mucosa with targeted metabolomics technology (LC-MS/MS). ASA-treated individuals (n = 27) had significantly lower tissue eicosanoid levels of most COX-derived metabolites than untreated individuals (n = 31). In contrast, COX-derived lipid metabolites tended to be higher in patients with statin treatment (n = 7) as compared with those not receiving statins (n = 24). This effect was not discernible in subjects treated with ASA and statins (n = 11): Individuals treated with both drugs showed a pronounced suppression of COX-derived eicosanoids in colon tissue, even compared with subjects treated with ASA alone. Our data from a routine clinical setting support the hypothesis that ASA and statins could inhibit CRC development via lipid mediator modification. Further studies should directly investigate the effect of dual ASA and statin treatment on colon tumorigenesis in humans. PMID- 29444937 TI - Maraviroc is associated with latent HIV-1 reactivation through NF-kappaB activation in resting CD4+ T cells from HIV-Infected Individuals on Suppressive Antiretroviral Therapy. AB - Maraviroc is a CCR5 antagonist used in the treatment of HIV-1 infection. We and others have suggested that maraviroc could reactivate latent HIV-1. To test the latency reversing potential of maraviroc and the mechanisms involved, we performed a phase-II, single-center, open-label study in which maraviroc was administered for 10 days to 20 HIV-1-infected individuals on suppressive antiretroviral therapy (Eudra CT: 2012-003215-66). All patients completed full maraviroc dosing and follow up. The primary endpoint was to study whether maraviroc may reactivate HIV-1 latency, eliciting signalling pathways involved in the viral reactivation. An increase in HIV-1 transcription in resting CD4+ T cells, estimated by HIV-1 unspliced RNA, was observed. Moreover, activation of the NF-kappaB transcription factor was observed in these cells. In contrast, AP-1 and NFAT activity was not detected. To elucidate the mechanism of NF-kappaB activation by maraviroc, we have evaluated in HeLa P4 C5 cells, which stably express CCR5, if maraviroc could be acting as a partial CCR5-agonist, with no other mechanisms or pathways involved. Our results show that maraviroc can induce NF-kappaB activity and NF-kappaB target genes expression by CCR5 binding, since the use of TAK779, a CCR5 inhibitor, blocked NF-kappaB activation and functionality. Taken together, we show that maraviroc may have a role in the activation of latent virus transcription through the activation of NF-kappaB as a result of binding CCR5. Our results strongly support a novel use of maraviroc as a potential latency reversal agent in HIV-1-infected patients.IMPORTANCE HIV-1 persistence in a small pool of long-lived latently infected resting CD4+ T-cells is a major barrier to viral eradication in HIV-1-infected patients on antiretroviral therapy. A potential strategy to cure HIV-1-infection is the use of latency reversing agents to eliminate the reservoirs established in resting CD4+ T-cells. As no drug has been shown to be completely effective so far, the search for new drugs and combinations remains a priority in the HIV cure. We examined the ability of maraviroc, a CCR5-antagonist used as an antiretroviral drug, to activate latent HIV-1 in infected-individuals on antiretroviral therapy. The study showed that maraviroc can activate NF-kappaB and, subsequently, induce latent HIV-1-transcription in resting CD4+ T-cells from HIV-1-infected individuals on suppressive antiretroviral therapy. Additional interventions will be needed to eliminate latent HIV-1 infection. Our results suggest that maraviroc may be a new latency reversing agent to interfere with HIV-1 persistence during antiretroviral therapy. PMID- 29444938 TI - Intranasal Live Influenza Vaccine Priming Elicits Localized B Cell Responses in Mediastinal Lymph Nodes. AB - Pandemic live attenuated influenza vaccines (pLAIV) prime subjects for a robust neutralizing antibody response upon subsequent administration of a pandemic inactivated subunit vaccine (pISV). However, a difference was not detected in H5 specific memory B cells in the peripheral blood between pLAIV-primed and unprimed subjects prior to pISV boost. To investigate the mechanism underlying pLAIV priming, we vaccinated groups of 12 African green monkeys (AGMs) with H5N1 pISV or pLAIV alone or H5N1 pLAIV followed by pISV and examined immunity systemically and in local draining lymph nodes (LN). The AGM model recapitulated the serologic observations from clinical studies. Interestingly, H5N1 pLAIV induced robust germinal center B cell responses in the mediastinal LN (MLN). Subsequent boosting with H5N1 pISV drove increases in H5-specific B cells in the axillary LN, spleen, and circulation in H5N1 pLAIV-primed animals. Thus, H5N1 pLAIV primes localized B cell responses in the MLN that are recalled systemically following pISV boost. These data provide mechanistic insights for the generation of robust humoral responses via prime-boost vaccination.IMPORTANCE We have previously shown that pandemic live attenuated influenza vaccines (pLAIV) prime for a rapid and robust antibody response on subsequent administration of inactivated subunit vaccine (pISV). This is observed even in individuals who had undetectable antibody (Ab) responses following the initial vaccination. To define the mechanistic basis of pLAIV priming, we turned to a nonhuman primate model and performed a detailed analysis of B cell responses in systemic and local lymphoid tissues following prime-boost vaccination with pLAIV and pISV. We show that the nonhuman primate model recapitulates the serologic observations from clinical studies. Further, we found that pLAIVs induced robust germinal center B cell responses in the mediastinal lymph node. Subsequent boosting with pISV in pLAIV-primed animals resulted in detection of B cells in the axillary lymph nodes, spleen, and peripheral blood. We demonstrate that intranasally administered pLAIV elicits a highly localized germinal center B cell response in the mediastinal lymph node that is rapidly recalled following pISV boost into germinal center reactions at numerous distant immune sites. PMID- 29444939 TI - Single-Cell Analysis of the Impact of Host Cell Heterogeneity on Infection with Foot-and-Mouth Disease Virus. AB - Viral infection and replication are affected by host cell heterogeneity, but the mechanisms underlying the effects remain unclear. Using single-cell analysis, we investigated the effects of host cell heterogeneity, including cell size, inclusion, and cell cycle, on foot-and-mouth disease virus (FMDV) infection (acute and persistent infections) and replication. We detected various viral genome replication levels in FMDV-infected cells. Large cells and cells with a high number of inclusions generated more viral RNA copies and viral protein and a higher proportion of infectious cells than other cells. Additionally, we found that the viral titer was 10- to 100-fold higher in cells in G2/M than those in other cell cycle phases and identified a strong correlation between cell size, inclusion, and cell cycle heterogeneity, which all affected the infection and replication of FMDV. Furthermore, we demonstrated that host cell heterogeneity influenced the adsorption of FMDV due to differences in the levels of FMDV integrin receptors expression. Collectively, these results further our understanding of the evolution of a virus in a single host cell.IMPORTANCE It is important to understand how host cell heterogeneity affects viral infection and replication. Using single-cell analysis, we found that viral genome replication levels exhibited dramatic variability in foot-and-mouth disease virus (FMDV) infected cells. We also found a strong correlation between heterogeneity in cell size, inclusion number, and cell cycle status and that all of these characteristics affect the infection and replication of FMDV. Moreover, we found that host cell heterogeneity influenced the viral adsorption as differences in the levels of FMDV integrin receptors' expression. This study provided new ideas for the studies of correlation between FMDV infection mechanisms and host cells. PMID- 29444940 TI - Dynamics of Evolution of Poliovirus Neutralizing Antigenic Sites and Other Capsid Functional Domains during a Large and Prolonged Outbreak. AB - We followed the dynamics of capsid amino acid replacement among 403 Nigerian outbreak isolates of type 2 circulating vaccine-derived poliovirus (cVDPV2) from 2005 through 2011. Four different functional domains were analyzed: 1) neutralizing antigenic (NAg) sites, 2) residues binding the poliovirus receptor (PVR), 3) VP1 residues 1-32, and 4) the capsid structural core. Amino acid replacements mapped to 37 of 43 positions across all 4 NAg sites; the most variable and polymorphic residues were in NAg sites 2 and 3b. The most divergent of the 120 NAg variants had no more than 5 replacements in all NAg sites, and were still neutralized at titers similar to those of Sabin 2. PVR-binding residues were less variable (25 different variants; 0-2 replacements/isolate; 30/44 invariant positions), with the most variable residues also forming parts of NAg sites 2 and 3a. Residues 1-32 of VP1 were highly variable (133 different variants; 0-6 replacements/isolate; 5/32 invariant positions), with residues 1-18 predicted to form a well-conserved amphipathic helix. Replacement events were dated by mapping them onto the branches of time-scaled phylogenies. Rates of amino acid replacement varied widely across positions and followed no simple substitution model. Replacements into the structural core were the most conservative and were fixed at an overall rate ~20-fold lower than rates for the NAg sites and VP1 1-32, and ~5-fold lower than the rate for the PVR-binding sites. Only VP1-143-Ile, a non-NAg site surface residue and known attenuation site, appeared to be under strong negative selection.IMPORTANCE The high rate of poliovirus evolution is offset by strong selection against amino acid replacement at most positions of the capsid. Consequently, poliovirus vaccines developed from strains isolated decades ago have been used worldwide to bring wild polioviruses almost to extinction. The apparent antigenic stability of poliovirus obscures a dynamic of continuous change within the neutralizing antigenic (NAg) sites. During seven years of a large outbreak in Nigeria, the circulating type 2 vaccine derived polioviruses generated 120 different NAg site variants via multiple independent pathways. Nonetheless, overall antigenic evolution was constrained, as no isolate had fixed more than 5 amino acid differences from the Sabin 2 NAg sites, and the most divergent isolates were efficiently neutralized by human immune sera. Evolution elsewhere in the capsid was also constrained. Amino acids binding the poliovirus receptor were strongly conserved, and extensive variation in the VP1 amino terminus still conserved a predicted amphipathic helix. PMID- 29444941 TI - Lactic Acid Downregulates Viral MicroRNA To Promote Epstein-Barr Virus Immortalized B Lymphoblastic Cell Adhesion and Growth. AB - High plasma lactate is associated with poor prognosis of many malignancies, but its role in virally mediated cancer progression and underlying molecular mechanisms are unclear. Epstein-Barr virus (EBV), the first human oncogenic virus, causes several cancers, including B-cell lymphoma. Here, we report that lactate dehydrogenase A (LDH-A) expression and lactate production are elevated in EBV-immortalized B lymphoblastic cells, and lactic acid (LA; acidic lactate) at low concentration triggers EBV-infected B-cell adhesion, morphological changes, and proliferation in vitro and in vivo Moreover, LA-induced responses of EBV infected B cells uniquely occurs in viral latency type III, and it is dramatically associated with the inhibition of global viral microRNAs, particularly the miR-BHRF1 cluster, and the high expression of SMAD3, JUN, and COL1A genes. The introduction of miR-BHRF1-1 blocks the LA-induced effects of EBV infected B cells. Thus, this may be a novel mechanism to explain EBV-immortalized B lymphoblastic cell malignancy in an LA microenvironment.IMPORTANCE The tumor microenvironment is complicated, and lactate, which is created by cell metabolism, contributes to an acidic microenvironment that facilitates cancer progression. However, how LA operates in virus-associated cancers is unclear. Thus, we studied how EBV (the first tumor virus identified in humans; it is associated with many cancers) upregulates the expression of LDH-A and lactate production in B lymphoma cells. Elevated LA induces adhesion and the growth of EBV-infected B cells by inhibiting viral microRNA transcription. Thus, we offer a novel understanding of how EBV utilizes an acidic microenvironment to promote cancer development. PMID- 29444942 TI - A Functional Link between RNA Replication and Virion Assembly in the Potyvirus Plum Pox Virus. AB - Accurate assembly of viral particles in the potyvirus Plum pox virus (PPV) has been shown to depend on the contribution of the multifunctional viral protein HCPro. In this study, we show that other viral factors, in addition to the capsid protein (CP) and HCPro, are necessary for the formation of stable PPV virions. The CP produced in Nicotiana benthamiana leaves from a subviral RNA termed LONG, which expresses a truncated polyprotein that lacks P1 and HCPro, together with HCPro supplied in trans, was assembled into virus-like particles and remained stable after in vitro incubation. In contrast, deletions in multiple regions of the LONG coding sequence prevented the CP stabilization mediated by HCPro. In particular, we demonstrated that the first 178 amino acids of P3, but not a specific nucleotide sequence coding for them, are required for CP stability and proper assembly of PPV particles. Using a sequential coagroinfiltration assay, we observed that the subviral LONG RNA replicates and locally spreads in N. benthamiana leaves expressing an RNA silencing suppressor. The analysis of the effect of both point and deletion mutations affecting RNA replication in LONG and full-length PPV demonstrated that this process is essential for the assembly of stable viral particles. Interestingly, in spite of this requirement, the CP produced by a nonreplicating viral RNA can be stably assembled into virions as long as it is coexpressed with a replication-proficient RNA. Altogether, these results highlight the importance of coupling encapsidation to other viral processes to secure a successful infection.IMPORTANCE Viruses of the family Potyviridae are among the most dangerous threats for basically every important crop, and such socioeconomical relevance has made them a subject of many research studies. In spite of this, very little is currently known about proteins and processes controlling viral genome encapsidation by the coat protein. In the case of Plum pox virus (genus Potyvirus), for instance, we have previously shown that the multitasking viral factor HCPro plays a role in the production of stable virions. Here, by using this potyvirus as a model, we move further to show that additional factors are also necessary for the efficient production of potyviral particles. More importantly, a comprehensive screening for such factors led us to the identification of a functional link between virus replication and packaging, unraveling a previously unknown connection of these two key events of the potyviral infection cycle. PMID- 29444943 TI - Vaccinia Virus C9 Ankyrin Repeat/F-Box Protein Is a Newly Identified Antagonist of the Type I Interferon-Induced Antiviral State. AB - Type I interferons (IFNs) induce expression of more than 300 cellular genes that provide protection against viruses and other pathogens. For survival, viruses evolved defenses to prevent the IFN response or counteract the IFN-induced antiviral state. However, because viruses and cells coevolved, the dynamic relationship between virus and host is difficult to discern. In the present study, we demonstrated that vaccinia virus with a large deletion near the left end of the genome had a diminished ability to replicate in cells that had been pretreated with beta interferon (IFN-beta), suggesting that one or more of the missing 17 open reading frames (ORFs) encode an antagonist of the IFN-induced antiviral state. By systematically deleting groups of ORFs and then individual ORFs, the C9L gene was shown to be required for IFN resistance. Replication of the C9L deletion mutant (vDeltaC9) was impaired in human cells that had been pretreated with IFN-beta. Expression of viral early genes occurred, but subsequent events, including genome uncoating, genome replication, and postreplicative gene expression, were inhibited. Expression of the C9 protein occurred prior to genome replication, consistent with an early role in counteracting the IFN-induced antiviral state. C9 contains six ankyrin repeat motifs and a near C-terminal F-box. Mass spectrometry and immunoblotting identified host proteins that copurified with a functional epitope-tagged C9. The most abundant proteins were components of the SCF (CUL1, SKP1, F-box) and signalosome/deneddylation complexes, which interact with each other, suggesting a possible role in proteolysis of one or more interferon-induced proteins.IMPORTANCE Poxviruses comprise a family of large DNA viruses that replicate in the cytoplasm of vertebrate and insect hosts and cause human and zoonotic diseases. In most cases the primary infection is moderated by innate immune defenses. Vertebrates, including fish, amphibians, reptiles, birds, and mammals, all produce type I interferon homologs. In humans, interferon stimulates the synthesis of more than 300 proteins thought to have roles in host defense. Conversely, viruses have evolved means to thwart the host defenses. We are attempting to deconstruct the established virus-host relationship in order to better understand the molecular mechanisms involved. In the present study, we identified a vaccinia virus gene that prevents interferon-mediated inhibition of very early stages of viral replication and is conserved in orthopoxviruses. The viral protein was shown to interact with host proteins involved in proteolysis, suggesting that vaccinia virus may subvert the cellular apparatus for its own defense. PMID- 29444944 TI - The 38K-Mediated Specific Dephosphorylation of the Viral Core Protein P6.9 Plays an Important Role in the Nucleocapsid Assembly of Autographa californica Multiple Nucleopolyhedrovirus. AB - Encapsidation of the viral genomes, leading to the assembly of the nucleocapsids to form infectious progeny virions, is a key step in many virus life cycles. Baculovirus nucleocapsid assembly is a complex process that involves many proteins. Our previous studies showed that the deletion of the core gene 38K (ac98) interrupted the nucleocapsid assembly by producing capsid sheaths devoid of viral genomes by an unknown mechanism. All homologs of 38K contain conserved motifs of the haloacid dehalogenase superfamily, which are involved in phosphoryl transfer. The requirements of these motifs for nucleocapsid assembly, confirmed in the present study, suggest that 38K may be a functioning haloacid dehalogenase. P6.9 is also encoded by a core gene (ac100) and is required for viral genome encapsidation. It has been reported that multiple phosphorylated species of P6.9 are present in virus-infected cells, while only an unphosphorylated species is detected in the budded virus. Therefore, whether 38K mediates the dephosphorylation of P6.9 was investigated. An additional phosphorylated species of P6.9 in 38K-deleted or -mutated virus-transfected cells was detected, and the dephosphorylated sites mediated by 38K were determined by mass spectrometry. To assess the effects of dephosphorylation of P6.9 mediated by 38K on virus replication, these sites were mutated to glutamic acids (phosphorylation-mimic mutant) or to alanines (phosphorylation-deficient mutant). Studies showed that the nucleocapsid assembly was interrupted in phosphorylation mimic mutant virus-transfected cells. Taken together, our findings demonstrate that 38K mediates the dephosphorylation of specific sites at the C terminus of P6.9, which is essential for viral genome encapsidation.IMPORTANCE Genome packaging is a fundamental process in the virus life cycle, and viruses have different strategies to perform this step. For several double-stranded DNA (dsDNA) viruses, the procapsid is formed before genome encapsidation, which may require basic proteins that help to neutralize the nucleic acid charge repulsion to facilitate the compaction of the genome within the confined capsid space. Baculovirus encodes a small basic protein, P6.9, which is required for a variety of processes in the virus infection cycle. The phosphorylation of P6.9 is thought to result in nucleocapsid uncoating, while the dephosphorylation of P6.9 is involved in viral DNA encapsidation during nucleocapsid assembly. Here, we demonstrate that a haloacid dehalogenase homolog encoded by baculovirus core gene 38K is involved in nucleocapsid assembly by mediating the dephosphorylation of 5 specific sites at the C terminus of P6.9. This finding contributes to the understanding of the mechanisms of virus nucleocapsid assembly. PMID- 29444945 TI - Interaction of Human Cytomegalovirus Tegument Proteins ppUL35 and ppUL35A with Sorting Nexin 5 Regulates Glycoprotein B (gpUL55) Localization. AB - Human cytomegalovirus (HCMV) is a widespread human pathogen that causes asymptomatic infection in healthy individuals but poses a serious threat to immunocompromised patients. During the late phase of HCMV infection, the viral capsid is transported to the cytoplasmic viral assembly center (cVAC), where it is enclosed by the tegument protein layer and the viral envelope. The cVAC consists of circularly arranged vesicles from the trans-Golgi and endosomal networks. The HCMV gene UL35 encodes ppUL35 and its shorter form, ppUL35A. We have previously shown that the UL35 gene is involved in HCMV assembly, but it is unknown how UL35 proteins regulate viral assembly. Here we show that sorting nexin 5 (SNX5), a component of the retromer and part of the retrograde transport pathway, interacts with UL35 proteins. Expression of wild-type proteins but not mutants defective in SNX5 binding resulted in the cellular redistribution of the cation-independent mannose-6-phosphate receptor (CI-M6PR), indicating that UL35 proteins bind and negatively regulate SNX5 to modulate cellular transport pathways. Furthermore, binding of UL35 proteins to SNX5 was required for efficient viral replication and for transport of the most abundant HCMV glycoprotein B (gB; gpUL55) to the cVAC. These results indicate that ppUL35 and ppUL35A control the localization of the essential gB through the regulation of a retrograde transport pathway. Thus, this work is the first to define a molecular interaction between a tegument protein and a vesicular transport factor to regulate glycoprotein localization.IMPORTANCE Human cytomegalovirus is ubiquitously present in the healthy population, but reactivation or reinfection can cause serious, life-threatening infections in immunocompromised patients. For completion of its lytic cycle, human cytomegalovirus induces formation of an assembly center where mature virus particles are formed from multiple viral proteins. Viral glycoproteins use separate vesicular pathways for transport to the assembly center, which are incompletely understood. Our research identified a viral structural protein which affects the localization of one of the major glycoproteins. We could link this change in glycoprotein localization to an interaction of the structural protein with a cellular protein involved in regulation of vesicle transport. This increases our understanding of how the virus intersects into cellular regulatory pathways to enhance its own replication. PMID- 29444946 TI - Karyopherin Alpha 6 Is Required for Replication of Porcine Reproductive and Respiratory Syndrome Virus and Zika Virus. AB - Movement of macromolecules between the cytoplasm and the nucleus occurs through the nuclear pore complex (NPC). Karyopherins comprise a family of soluble transport factors facilitating the nucleocytoplasmic translocation of proteins through the NPC. In this study, we found that karyopherin alpha6 (KPNA6; also known as importin alpha7) was required for the optimal replication of porcine reproductive and respiratory syndrome virus (PRRSV) and Zika virus (ZIKV), which are positive-sense, single-stranded RNA viruses replicating in the cytoplasm. The KPNA6 protein level in virus-infected cells was much higher than that in mock infected controls, whereas the KPNA6 transcript remains stable. Viral infection blocked the ubiquitin-proteasomal degradation of KPNA6, which led to an extension of the KPNA6 half-life and the elevation of the KPNA6 level in comparison to mock infected cells. PRRSV nsp12 protein induced KPNA6 stabilization. KPNA6 silencing was detrimental to the replication of PRRSV, and KPNA6 knockout impaired ZIKV replication. Moreover, KPNA6 knockout blocked the nuclear translocation of PRRSV nsp1beta but had a minimal effect on two other PRRSV proteins with nuclear localization. Exogenous restitution of KPNA6 expression in the KPNA6-knockout cells results in restoration of the nuclear translocation of PRRSV nsp1beta and the replication of ZIKV. These results indicate that KPNA6 is an important cellular factor for the replication of PRRSV and ZIKV.IMPORTANCE Positive-sense, single-stranded RNA (+ssRNA) viruses replicate in the cytoplasm of infected cells. The roles of transport factors in the nucleocytoplasmic trafficking system for the replication of +ssRNA viruses are not known. In this study, we discovered that PRRSV and ZIKV viruses needed karyopherin alpha6 (KPNA6), one of the transport factors, to enhance the virus replication. Our data showed that viral infection induced an elevation of the KPNA6 protein level due to an extension of the KPNA6 half-life via viral interference of the ubiquitin-proteasomal degradation of KPNA6. Notably, KPNA6 silencing or knockout dramatically reduced the replication of PRRSV and ZIKV. PRRSV nsp1beta depended on KPNA6 to translocate into the nucleus. In addition, exogenous restitution of KPNA6 expression in KPNA6-knockout cells led to the restoration of nsp1beta nuclear translocation and ZIKV replication. These results reveal a new aspect in the virus-cell interaction and may facilitate the development of novel antiviral therapeutics. PMID- 29444947 TI - Hepatitis C Virus core+1/ARF Protein Modulates the Cyclin D1/pRb Pathway and Promotes Carcinogenesis. AB - Viruses often encompass overlapping reading frames and unconventional translation mechanisms in order to maximize the output from a minimum genome and to orchestrate their timely gene expression. Hepatitis C virus (HCV) possesses such an unconventional open reading frame (ORF) within the core-coding region, encoding an additional protein, initially designated ARFP, F, or core+1. Two predominant isoforms of core+1/ARFP have been reported, core+1/L, initiating from codon 26, and core+1/S, initiating from codons 85/87 of the polyprotein coding region. The biological significance of core+1/ARFP expression remains elusive. The aim of the present study was to gain insight into the functional and pathological properties of core+1/ARFP through its interaction with the host cell, combining in vitro and in vivo approaches. Our data provide strong evidence that the core+1/ARFP of HCV-1a stimulates cell proliferation in Huh7-based cell lines expressing either core+1/S or core+1/L isoforms and in transgenic liver disease mouse models expressing core+1/S protein in a liver-specific manner. Both isoforms of core+1/ARFP increase the levels of cyclin D1 and phosphorylated Rb, thus promoting the cell cycle. In addition, core+1/S was found to enhance liver regeneration and oncogenesis in transgenic mice. The induction of the cell cycle together with increased mRNA levels of cell proliferation-related oncogenes in cells expressing the core+1/ARFP proteins argue for an oncogenic potential of these proteins and an important role in HCV-associated pathogenesis.IMPORTANCE This study sheds light on the biological importance of a unique HCV protein. We show here that core+1/ARFP of HCV-1a interacts with the host machinery, leading to acceleration of the cell cycle and enhancement of liver carcinogenesis. This pathological mechanism(s) may complement the action of other viral proteins with oncogenic properties, leading to the development of hepatocellular carcinoma. In addition, given that immunological responses to core+1/ARFP have been correlated with liver disease severity in chronic HCV patients, we expect that the present work will assist in clarifying the pathophysiological relevance of this protein as a biomarker of disease progression. PMID- 29444948 TI - The Superimposed Deubiquitination Effect of OTULIN and Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) Nsp11 Promotes Multiplication of PRRSV. AB - Linear ubiquitination plays an important role in the regulation of the immune response by regulating nuclear factor kappaB (NF-kappaB). The linear ubiquitination-specific deubiquitinase ovarian tumor domain deubiquitinase with linear linkage specificity (OTULIN) can control the immune signaling transduction pathway by restricting the Met1-linked ubiquitination process. In our study, the porcine OTLLIN gene was cloned and deubiquitin functions were detected in a porcine reproductive and respiratory syndrome virus (PRRSV)-infected-cell model. PRRSV infection promotes the expression of the OTULIN gene; in turn, overexpression of OTULIN contributes to PRRSV proliferation. There is negative regulation of innate immunity with OTULIN during viral infection. The cooperative effects of swine OTULIN and PRRSV Nsp11 potentiate the ability to reduce levels of cellular protein ubiquitin associated with innate immunity. Importantly, PRRSV Nsp11 recruits OTULIN through a nonenzymatic combination to enhance its ability to remove linear ubiquitination targeting NEMO, resulting in a superimposed effect that inhibits the production of type I interferons (IFNs). Our report presents a new model of virus utilization of the ubiquitin-protease system in vivo from the perspective of the viral proteins that interact with cell deubiquitination enzymes, providing new ideas for prevention and control of PRRSV.IMPORTANCE Deubiquitination effects of swine OTULIN were identified. The interaction between porcine OTULIN and PRRSV Nsp11 is dependent on the OTU domain. PRRSV Nsp11 recruits OTULIN through a nonenzymatic combination to promote removal of linear ubiquitination targeting NEMO, resulting in a superimposed effect that inhibits the production of type I IFNs. PMID- 29444950 TI - miRNA targeting and alternative splicing in the stress response - events hosted by membrane-less compartments. AB - Stress can be temporary or chronic, and mild or acute. Depending on its extent and severity, cells either alter their metabolism, and adopt a new state, or die. Fluctuations in environmental conditions occur frequently, and such stress disturbs cellular homeostasis, but in general, stresses are reversible and last only a short time. There is increasing evidence that regulation of gene expression in response to temporal stress happens post-transcriptionally in specialized subcellular membrane-less compartments called ribonucleoprotein (RNP) granules. RNP granules assemble through a concentration-dependent liquid-liquid phase separation of RNA-binding proteins that contain low-complexity sequence domains (LCDs). Interestingly, many factors that regulate microRNA (miRNA) biogenesis and alternative splicing are RNA-binding proteins that contain LCDs and localize to stress-induced liquid-like compartments. Consequently, gene silencing through miRNAs and alternative splicing of pre-mRNAs are emerging as crucial post-transcriptional mechanisms that function on a genome-wide scale to regulate the cellular stress response. In this Review, we describe the interplay between these two post-transcriptional processes that occur in liquid-like compartments as an adaptive cellular response to stress. PMID- 29444949 TI - Downregulation of MicroRNA eca-mir-128 in Seminal Exosomes and Enhanced Expression of CXCL16 in the Stallion Reproductive Tract Are Associated with Long Term Persistence of Equine Arteritis Virus. AB - Equine arteritis virus (EAV) can establish long-term persistent infection in the reproductive tract of stallions and is shed in the semen. Previous studies showed that long-term persistence is associated with a specific allele of the CXCL16 gene (CXCL16S) and that persistent infection is maintained despite the presence of a local inflammatory and humoral and mucosal antibody responses. In this study, we demonstrated that equine seminal exosomes (SEs) are enriched in a small subset of microRNAs (miRNAs). Most importantly, we demonstrated that long-term EAV persistence is associated with the downregulation of an SE-associated miRNA (eca-mir-128) and with an enhanced expression of CXCL16 in the reproductive tract, a putative target of eca-mir-128. The findings presented here suggest that SE eca-mir-128 is implicated in the regulation of the CXCL16/CXCR6 axis in the reproductive tract of persistently infected stallions, a chemokine axis strongly implicated in EAV persistence. This is a novel finding and warrants further investigation to identify its specific mechanism in modulating the CXCL16/CXCR6 axis in the reproductive tract of the EAV long-term carrier stallion.IMPORTANCE Equine arteritis virus (EAV) has the ability to establish long-term persistent infection in the stallion reproductive tract and to be shed in semen, which jeopardizes its worldwide control. Currently, the molecular mechanisms of viral persistence are being unraveled, and these are essential for the development of effective therapeutics to eliminate persistent infection. Recently, it has been determined that long-term persistence is associated with a specific allele of the CXCL16 gene (CXCL16S) and is maintained despite induction of local inflammatory, humoral, and mucosal antibody responses. This study demonstrated that long-term persistence is associated with the downregulation of seminal exosome miRNA eca mir-128 and enhanced expression of its putative target, CXCL16, in the reproductive tract. For the first time, this study suggests complex interactions between eca-mir-128 and cellular elements at the site of EAV persistence and implicates this miRNA in the regulation of the CXCL16/CXCR6 axis in the reproductive tract during long-term persistence. PMID- 29444954 TI - Invite your representative to work. Change the world. Here's how. AB - Today's political climate can seem hostile to science. Alternative facts, climate change denial, and relabeling of actual news as fake news are discouraging phenomena for sure. But these trends make it more important than ever to engage our politicians. Take heart! There is something you can do. You can show your representatives firsthand the amazing things you do, evidence of the economic engine that your activities generate, and the real people behind the discoveries. I did, and it was fun. We invited our congressman to the University of California, Santa Barbara (UCSB), and he accepted! For 2 hours, we explained and demonstrated efforts to cure blindness using stem cells, the medical implications of the discovery that cells can recover from the brink of death, a mosquito lab striving to eliminate insect-borne disease, and an Alzheimer's disease laboratory. Salud Carbajal peered through a microscope and met real scientists. Before his visit, he did not know what a postdoctoral fellow was, much less what stem cells look like. When he left he knew our names, how much money we bring into his district, and how important National Institutes of Health funding and international mobility are to our enterprise. Although I live in the United States, this approach should also apply to other democratic countries. If each of us converts one representative into a science champion, we can change the world. PMID- 29444955 TI - Common and divergent features of galactose-1-phosphate and fructose-1-phosphate toxicity in yeast. AB - Metabolic dysregulation leading to sugar-phosphate accumulation is toxic in organisms ranging from bacteria to humans. By comparing two models of sugar phosphate toxicity in Saccharomyces cerevisiae, we demonstrate that toxicity occurs, at least in part, through multiple, isomer-specific mechanisms, rather than a single general mechanism. PMID- 29444956 TI - Dual-color metal-induced and forster resonance energy transfer for cell nanoscopy. AB - We report a novel method, dual color axial nanometric localization by Metal Induced Energy Transfer (dcMIET), and combine it with Forster Resonant Energy Transfer (FRET) for resolving structural details in cells on the molecular level. We demonstrate the capability of this method on cytoskeletal elements and adhesions in human mesenchymal stem cells (hMSCs). Our approach is based on Fluorescence-Lifetime-Imaging Microscopy (FLIM), and allows for precise determination of the 3D architecture of stress fibers anchoring at focal adhesions, thus yielding crucial information to understand cell-matrix mechanics. In addition to resolving nanometric structural details along the z-axis, we use FRET to gain precise information on the distance between actin and vinculin at focal adhesions. PMID- 29444953 TI - Staphylococcal Osteomyelitis: Disease Progression, Treatment Challenges, and Future Directions. AB - Osteomyelitis is an inflammatory bone disease that is caused by an infecting microorganism and leads to progressive bone destruction and loss. The most common causative species are the usually commensal staphylococci, with Staphylococcus aureus and Staphylococcus epidermidis responsible for the majority of cases. Staphylococcal infections are becoming an increasing global concern, partially due to the resistance mechanisms developed by staphylococci to evade the host immune system and antibiotic treatment. In addition to the ability of staphylococci to withstand treatment, surgical intervention in an effort to remove necrotic and infected bone further exacerbates patient impairment. Despite the advances in current health care, osteomyelitis is now a major clinical challenge, with recurrent and persistent infections occurring in approximately 40% of patients. This review aims to provide information about staphylococcus induced bone infection, covering the clinical presentation and diagnosis of osteomyelitis, pathophysiology and complications of osteomyelitis, and future avenues that are being explored to treat osteomyelitis. PMID- 29444957 TI - P38 activation induces the dissociation of tristetraprolin from Argonaute 2 to increase ARE-mRNA stabilization. AB - ARE-mRNAs are actively degraded with tristetraprolin (TTP) in resting cells while they turn into stable messengers in activated cells. P38 plays a crucial role in stabilizing ARE-mRNA. Here we reveal that P38 activation represses the interaction between TTP and Ago2, thus restraining TTP from being targeted into processing bodies and stabilizing ARE-mRNA. PMID- 29444952 TI - Treatment of Infections Caused by Extended-Spectrum-Beta-Lactamase-, AmpC-, and Carbapenemase-Producing Enterobacteriaceae. AB - Therapy of invasive infections due to multidrug-resistant Enterobacteriaceae (MDR E) is challenging, and some of the few active drugs are not available in many countries. For extended-spectrum beta-lactamase and AmpC producers, carbapenems are the drugs of choice, but alternatives are needed because the rate of carbapenem resistance is rising. Potential active drugs include classic and newer beta-lactam-beta-lactamase inhibitor combinations, cephamycins, temocillin, aminoglycosides, tigecycline, fosfomycin, and, rarely, fluoroquinolones or trimethoprim-sulfamethoxazole. These drugs might be considered in some specific situations. AmpC producers are resistant to cephamycins, but cefepime is an option. In the case of carbapenemase-producing Enterobacteriaceae (CPE), only some "second-line" drugs, such as polymyxins, tigecycline, aminoglycosides, and fosfomycin, may be active; double carbapenems can also be considered in specific situations. Combination therapy is associated with better outcomes for high-risk patients, such as those in septic shock or with pneumonia. Ceftazidime-avibactam was recently approved and is active against KPC and OXA-48 producers; the available experience is scarce but promising, although development of resistance is a concern. New drugs active against some CPE isolates are in different stages of development, including meropenem-vaborbactam, imipenem-relebactam, plazomicin, cefiderocol, eravacycline, and aztreonam-avibactam. Overall, therapy of MDR-E infection must be individualized according to the susceptibility profile, type, and severity of infection and the features of the patient.

AB - Cdc48/p97 and the ubiquilin family of UBA-UBL proteins are known for their role in the retrotranslocation of damaged proteins from the endoplasmic reticulum. We demonstrate that Cdc48 and the ubiquilin-like proteins in yeast also play a role in the anterograde trafficking of proteins, in this case the vacuolar protease, Cps1. PMID- 29444959 TI - The synaptotagmin C2B domain calcium-binding loops modulate the rate of fusion pore expansion. AB - In chromaffin cells, the kinetics of fusion pore expansion vary depending on which synaptotagmin isoform (Syt-1 or Syt-7) drives release. Our recent studies have shown that fusion pores of granules harboring Syt-1 expand more rapidly than those harboring Syt-7. Here, we sought to define the structural specificity of synaptotagmin action at the fusion pore by manipulating the Ca2+-binding C2B module. We generated a chimeric Syt-1 in which its C2B Ca2+-binding loops had been exchanged for those of Syt-7. Fusion pores of granules harboring a Syt-1 C2B chimera with all three Ca2+-binding loops of Syt-7 (Syt-1:7C2B123) exhibited slower rates of fusion pore expansion and neuropeptide cargo release relative to WT Syt-1. After fusion, this chimera also dispersed more slowly from fusion sites than WT protein. We speculate that the Syt-1:7 C2B123 and WT Syt-1 are likely to differ in their interactions with Ca2+ and membranes. Subsequent in vitro and in silico data demonstrated that the chimera exhibits a higher affinity for phospholipids than WT Syt-1. We conclude that the affinity of synaptotagmin for the plasma membrane, and the rate at which it releases the membrane, contribute in important ways to the rate of fusion pore expansion.

AB - Herein, we describe a technique for stent-assisted coil embolization with a spring-shaped microcatheter in a patient with an M1 ultrawide-necked circumferential aneurysm in the middle cerebral artery (MCA). A 49-year-old man was referred for treatment of an incidentally detected M1 large-circumference aneurysm on magnetic resonance angiography. Subsequent digital subtraction angiography revealed an 18.2*16.5 mm ultrawide-necked circumferential aneurysm on the distal M1 portion of the left MCA, and we planned stent-assisted coil embolization using a spring-shaped microcatheter. After we deployed the stent, we performed coil embolization under the down-the-barrel view by pulling out the microcatheter little by little. Using this technique, we could fill the coil mass evenly into the aneurysmal sac around the stent. And there were no immediate or delayed complications after the procedure. Stent-assisted coiling using a spring shaped microcatheter is a useful and safe technique for treating ultrawide-necked circumferential aneurysm or fusiform aneurysms.

AB - INTRODUCTION: Mechanical thrombectomy (MT) has been widely accepted as a safe and effective treatment for acute ischemic stroke (AIS). Development of stent retriever devices has been intensively developed over the past two decades. In this study, we compared the effectiveness and safety of a new thrombectomy device with Solitaire FR for the treatment of AIS models. METHODS: Mechanical performance of stent retrievers was tested in vitro. Thrombin-induced thrombus was pre-injected into the right distal external carotid-maxillary artery in 18 dogs to create an acute thrombus occlusion model, and these animals were divided into a Tonbridge group (n=9, with Tonbridge stent Tonbridge Medical Technology) and a Solitaire group as control (n=9, with Solitaire stent, ev3 Neurovascular). Final flow restoration, side branches, recanalization time, distal vessel embolism, and device-related complications were recorded and compared. A post procedure angiogram was obtained at 30 and 90 days after thrombectomy. Device manipulation-related damage to the arterial walls was evaluated histologically. RESULTS: In vitro test showed that the maximum friction within the microcatheter was 0.763 for the Tonbridge device and 0.784 n for the Solitaire (P>0.05). Slight increase in radial force was noticed for the Tonbridge (0.035 N/mm vs 0.031 N/mm of Solitaire, P>0.05). Eighteen and 16 retriever attempts were done in the Tonbridge (mean 2.0 attempts) and the Solitaire (mean 1.8 attempts) groups (P=0.74). The Tonbridge device led to good flow restoration in all nine (100%) models compared with eight (88.9%) in the Solitaire group (P=0.30). Side branches' influence (P=0.39), distal thromboembolism (P=0.60), and device-related complications (P=1.00) found no difference between the two groups. The rates of disruption of the internal elastic lamina (IEL) were 8.3% (2/24) and 4.2% (1/24) of the specimens, respectively (P=0.683). TICI 2b/3 flow of the right CCA were similar between the two groups at 1 (6/6 vs 6/6) and 3 months (6/6 vs 6/6) follow up (P>0.05). CONCLUSION: Our preliminary study indicated this new device was technically feasible and effective to be used in thrombectomy for the treatment of acute thrombus occlusion in canine models.

AB - Here we report, for the first time, a combination of five-vessel aortic arch, anomalous origin of the right vertebral artery (VA) from the common carotid artery (CCA), an aberrant right subclavian artery (SCA), and bilateral symmetrical segmental agenesis of VAs.In this case report, we present a patient with moyamoya syndrome (MMS) and Down syndrome (DS) who has bilateral symmetrical segmental agenesis of VAs, left VA originating from aortic arch and anomalous origin of right VA arising from CCA in combination with an aberrant right SCA. Therefore, five vessels are originating from aortic arch. Here, we report, for the first time, a combination of five-vessel aortic arch with an aberrant right SCA and symmetrical segmental agenesis of both VAs. The possible embryological mechanisms of the anomalies as well as an relation with MMS and DS are discussed.

AB - A 71-year-old man who had a L1/S1 posterior fusion revision surgery complained of increasing back pain 5 weeks after the open surgical procedure. The pain was initially estimated at 9/10 on the visual analog scale (VAS) and thought to be related to a right-sided L2 screw loosening. A right parapedicular vertebroplasty was performed and polymethylmethacrylate cement was instilled around the right pedicle screw, filling the anterior two-thirds of the vertebral body. On postvertebroplasty day 1, the patient had significant improvement in his low back pain. The pain further decreased at 1 and 3 months after the intervention (2/10 on the VAS). Vertebroplasty is a minimally invasive, accessible, effective, and long lasting treatment for compression fractures. We believe that this technique could also be indicated to treat pain related to low grade screw loosening in properly selected patients. PMID- 29444964 TI - Electrical stimulation of the dorsolateral prefrontal cortex impairs semantic cognition. AB - OBJECTIVE: To identify the prefrontal cortical structures causally involved in verbal and nonverbal semantic cognition in both cerebral hemispheres. METHODS: We retrospectively screened the intraoperative brain mapping data of 584 patients who underwent neurosurgery for neoplastic tumor under local anesthesia with direct cortical electrostimulation. Patients were included if they were right handed, recently diagnosed with a diffuse low-grade glioma, and had a positive language mapping for verbal (naming task) and nonverbal (visual semantic association task) semantic cognition in the prefrontal cortex (n = 49). Among these, 30 were tested intraoperatively with both the naming and the semantic association tasks, while 19 were tested with the naming task only. Subsequently, each semantic site (n = 85) was plotted individually onto a common stereotaxic space for detailed analyses. RESULTS: The cortical sites associated with verbal semantic disturbances (n = 45) were distributed in the pars opercularis (n = 14) and pars triangularis (n = 19) of the left inferior frontal gyrus, and left dorsolateral prefrontal cortex (dlPFC, n = 12); only 2 sites were observed in the right dlPFC. In contrast, all but one cortical site associated with nonverbal semantic disturbances were observed in the left dorsolateral cortex (n = 8). In the right hemisphere, the same disturbances were found in the dlPFC (n = 14) and pars opercularis (n = 2). CONCLUSION: The present study demonstrated the critical role of the dlPFC in the semantic network, and indicated its specific and bilateral involvement in nonverbal semantic cognition in right-handers.

AB - OBJECTIVE: To reveal the prevalence and localization of cerebral microbleeds (CMBs) in the 3 main variants of primary progressive aphasia (PPA) (logopenic, semantic, and nonfluent/agrammatic), to identify the relationship with underlying Alzheimer pathology, and to explore whether CMBs contribute to language breakdown. METHODS: We used a cross-sectional design in a multicenter cohort of 82 patients with PPA and 19 similarly aged healthy controls. MRI allowed for rating CMBs (2-dimensional gradient recalled echo T2*, susceptibility weighted imaging sequences) and white matter hyperintensities. CSF Alzheimer disease biomarker analyses available in 63 of the 82 patients provided the stratification of PPA into subgroups with patients who had or did not have probable underlying Alzheimer pathology. RESULTS: The prevalence of CMBs was higher in patients with PPA (28%) than in controls (16%). They were more prevalent in logopenic PPA (50%) than in semantic PPA (18%) and nonfluent/agrammatic PPA (17%). The localization of CMBs was mainly lobar (81%) with no difference between the PPA variants. CMBs were more frequent in PPA patients with positive than with negative CSF Alzheimer disease biomarkers (67% vs 20%). Patients with and without lobar CMBs had similar volumes of white matter hyperintensities. Language and general cognitive impairment in PPA was unrelated to CMB rates. CONCLUSIONS: CMB prevalence in PPA is higher than in healthy controls. CMBs were most prevalent in the logopenic variant, were related to underlying Alzheimer pathology, and did not affect the language/cognitive impairment. Our findings also suggest that CMB detection with MRI contributes to PPA variant diagnosis, especially of logopenic PPA, and provides an estimator of the underlying neuropathology. PMID- 29444968 TI - Behavioral interventions as a treatment for epilepsy: A multicenter randomized controlled trial. AB - OBJECTIVE: To evaluate the effect of a stress-reduction intervention in participants with medication-resistant epilepsy. METHODS: Adults with medication resistant focal epilepsy (n = 66) were recruited from 3 centers and randomized to 1 of 2 interventions: (1) progressive muscle relaxation (PMR) with diaphragmatic breathing, or (2) control focused-attention activity with extremity movements. Following an 8-week baseline period, participants began 12 weeks of double-blind treatment. Daily self-reported mood and stress ratings plus seizure counts were completed by participants using an electronic diary, and no medication adjustments were permitted. The primary outcome was percent reduction in seizure frequency per 28 days comparing baseline and treatment; secondary outcomes included stress reduction and stress-seizure interaction. RESULTS: In the 66 participants in the intention-to-treat analysis, seizure frequency was reduced from baseline in both treatment groups (PMR: 29%, p < 0.05; focused attention: 25%, p < 0.05). PMR and focused attention did not differ in seizure reduction (p = 0.38), although PMR was associated with stress reduction relative to focused attention (p < 0.05). Daily stress was not a predictor of seizures. CONCLUSIONS: Both PMR and the focused-attention groups showed reduced seizure frequency compared to baseline in participants with medication-resistant focal seizures, although the 2 treatments did not differ. PMR was more effective than focused attention in reducing self-reported stress. CLINICALTRIALSGOV IDENTIFIER: NCT01444183. PMID- 29444970 TI - Cytoplasmic RNA granules, ribostasis, and neurodegeneration. PMID- 29444969 TI - Atrial fibrillation detected after stroke is related to a low risk of ischemic stroke recurrence. AB - OBJECTIVE: To compare the risk of 1-year ischemic stroke recurrence between atrial fibrillation (AF) diagnosed after stroke (AFDAS) and sinus rhythm (SR) and investigate whether underlying heart disease is as frequent in AFDAS as it is in AF known before stroke (KAF). METHODS: In this retrospective cohort study, we included all ischemic stroke patients admitted to institutions participating in the Ontario Stroke Registry from July 1, 2003, to March 31, 2013. Based on heart rhythm assessed during admission, we classified patients as AFDAS, KAF, or SR. We modeled the relationship between heart rhythm groups and 1-year ischemic stroke recurrence by using Cox regression adjusted for multiple covariates (e.g., oral anticoagulants). We compared the prevalence of coronary artery disease, myocardial infarction, and heart failure among the 3 groups. RESULTS: Among 23,376 ischemic stroke patients, 15,885 had SR, 587 AFDAS, and 6,904 KAF. At 1 year, 39 (6.6%) patients with AFDAS, 661 (9.6%) with KAF, and 1,269 (8.0%) with SR had recurrent ischemic strokes (p = 0.0001). AFDAS-related ischemic stroke recurrence adjusted risk was not different from that of SR (hazard ratio 0.90 [95% confidence interval 0.63, 1.30]; p = 0.57). Prevalence of coronary artery disease (18.2% vs 34.7%; p < 0.0001), myocardial infarction (11.6% vs 20.5%; p < 0.0001), and heart failure (5.5% vs 16.8%; p < 0.0001) were lower in AFDAS relative to KAF. CONCLUSIONS: The lack of difference in 1-year ischemic stroke recurrence between AFDAS and SR and the lower prevalence of heart disease in AFDAS compared to KAF suggest that the underlying pathophysiology of AFDAS may differ from that of KAF. PMID- 29444971 TI - Anosognosia predicts default mode network hypometabolism and clinical progression to dementia. AB - OBJECTIVE: To identify the pathophysiologic mechanisms and clinical significance of anosognosia for cognitive decline in mild cognitive impairment. METHODS: We stratified 468 patients with amnestic mild cognitive impairment into intact and impaired awareness groups, determined by the discrepancy between the patient and the informant score on the Everyday Cognition questionnaire. Voxel-based linear regression models evaluated the associations between self-awareness status and baseline beta-amyloid load, measured by [18F]florbetapir, and the relationships between awareness status and regional brain glucose metabolism measured by [18F]fluorodeoxyglucose at baseline and at 24-month follow-up. Multivariate logistic regression tested the association of awareness status with conversion from amnestic mild cognitive impairment to dementia. RESULTS: We found that participants with impaired awareness had lower [18F]fluorodeoxyglucose uptake and increased [18F]florbetapir uptake in the posterior cingulate cortex at baseline. In addition, impaired awareness in mild cognitive impairment predicted [18F]fluorodeoxyglucose hypometabolism in the posterior cingulate cortex, left basal forebrain, bilateral medial temporal lobes, and right lateral temporal lobe over 24 months. Furthermore, participants with impaired awareness had a nearly 3 fold increase in likelihood of conversion to dementia within a 2-year time frame. CONCLUSIONS: Our results suggest that anosognosia is linked to Alzheimer disease pathophysiology in vulnerable structures, and predicts subsequent hypometabolism in the default mode network, accompanied by an increased risk of progression to dementia. This highlights the importance of assessing awareness of cognitive decline in the clinical evaluation and management of individuals with amnestic mild cognitive impairment. PMID- 29444972 TI - Usefulness of ADAMTS13 to predict response to recanalization therapies in acute ischemic stroke. AB - OBJECTIVE: We aimed to analyze ADAMTS13 (a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13) in relation to arterial recanalization in patients treated with IV tissue plasminogen activator (tPA) and in relation to futile recanalization in patients treated with mechanical thrombectomy. METHODS: Acute ischemic stroke patients (n = 108) with documented arterial occlusions treated with IV-tPA were selected. ADAMTS13 activity was measured by ELISA in samples collected before treatment. Recanalization was assessed at 2 hours by transcranial Doppler. In 78 consecutive patients treated with endovascular thrombectomy, ADAMTS13 antigen was measured by ELISA and futile recanalization was defined as complete recanalization plus modified Rankin Scale score >2 at 3 months. Independent predictors of recanalization and futile recanalization were determined by logistic regression, adjusted by age, NIH Stroke Scale score, and time from stroke onset. RESULTS: Patients who achieved tPA-induced recanalization had higher baseline ADAMTS13 activity (78.1% [68%-88%] vs 70.1% [61%-79%], p = 0.021). In logistic regression analysis, ADAMTS13 activity >75% was an independent predictor of recanalization (odds ratio = 6.76 [1.52-30.02], p = 0.012), together with absence of early ischemic signs and Oxfordshire Community Stroke Project classification. Regarding endovascular therapies, a reduced ADAMTS13 concentration (<982 ng/mL) was an independent predictor of futile recanalization (odds ratio = 67.4 [1.4-3,282.1], p = 0.034), together with age and diabetes mellitus. The addition of ADAMTS13 to clinical predictors of tPA induced recanalization and futile recanalization improved discrimination and reclassification (integrated discrimination improvement = 10.06% and 28.4%, net reclassification improvement = 61.0% and 107.4%, respectively). CONCLUSIONS: A reduced ADAMTS13 was associated with poor response to recanalization therapies. If confirmed in future prospective studies, a panel of blood biomarkers including ADAMTS13 might be a useful tool to guide reperfusion therapies. PMID- 29444973 TI - Eight-hours adaptive deep brain stimulation in patients with Parkinson disease. AB - OBJECTIVES: To assess the feasibility and clinical efficacy of local field potentials (LFPs)-based adaptive deep brain stimulation (aDBS) in patients with advanced Parkinson disease (PD) during daily activities in an open-label, nonblinded study. METHODS: We monitored neurophysiologic and clinical fluctuations during 2 perioperative experimental sessions lasting for up to 8 hours. On the first day, the patient took his/her daily medication, while on the second, he/she additionally underwent subthalamic nucleus aDBS driven by LFPs beta band power. RESULTS: The beta band power correlated in both experimental sessions with the patient's clinical state (Pearson correlation coefficient r = 0.506, p < 0.001, and r = 0.477, p < 0.001). aDBS after LFP changes was effective (30% improvement without medication [3-way analysis of variance, interaction day * medication p = 0.036; 30.5 +/- 3.4 vs 22.2 +/- 3.3, p = 0.003]), safe, and well tolerated in patients performing regular daily activities and taking additional dopaminergic medication. aDBS was able to decrease DBS amplitude during motor "on" states compared to "off" states (paired t test p = 0.046), and this automatic adjustment of STN-DBS prevented dyskinesias. CONCLUSIONS: The main findings of our study are that aDBS is technically feasible in everyday life and provides a safe, well-tolerated, and effective treatment method for the management of clinical fluctuations. CLASSIFICATION OF EVIDENCE: This study provides Class IV evidence that for patients with advanced PD, aDBS is safe, well tolerated, and effective in controlling PD motor symptoms.

PMID- 29444975 TI - Approaching adaptive control in neurostimulation for Parkinson disease: Autopilot on. PMID- 29444976 TI - FoxO transcription factors modulate autophagy and proteoglycan 4 in cartilage homeostasis and osteoarthritis. AB - Aging is a main risk factor for osteoarthritis (OA). FoxO transcription factors protect against cellular and organismal aging, and FoxO expression in cartilage is reduced with aging and in OA. To investigate the role of FoxO in cartilage, Col2Cre-FoxO1, 3, and 4 single knockout (KO) and triple KO mice (Col2Cre-TKO) were analyzed. Articular cartilage in Col2Cre-TKO and Col2Cre-FoxO1 KO mice was thicker than in control mice at 1 or 2 months of age. This was associated with increased proliferation of chondrocytes of Col2Cre-TKO mice in vivo and in vitro. OA-like changes developed in cartilage, synovium, and subchondral bone between 4 and 6 months of age in Col2Cre-TKO and Col2Cre-FoxO1 KO mice. Col2Cre-FoxO3 and FoxO4 KO mice showed no cartilage abnormalities until 18 months of age when Col2Cre-FoxO3 KO mice had more severe OA than control mice. Autophagy and antioxidant defense genes were reduced in Col2Cre-TKO mice. Deletion of FoxO1/3/4 in mature mice using Aggrecan(Acan)-CreERT2 (AcanCreERT-TKO) also led to spontaneous cartilage degradation and increased OA severity in a surgical model or treadmill running. The superficial zone of knee articular cartilage of Col2Cre TKO and AcanCreERT-TKO mice exhibited reduced cell density and markedly decreased Prg4 In vitro, ectopic FoxO1 expression increased Prg4 and synergized with transforming growth factor-beta stimulation. In OA chondrocytes, overexpression of FoxO1 reduced inflammatory mediators and cartilage-degrading enzymes, increased protective genes, and antagonized interleukin-1beta effects. Our observations suggest that FoxO play a key role in postnatal cartilage development, maturation, and homeostasis and protect against OA-associated cartilage damage.

AB - Herpes simplex virus type 1 (HSV-1) causes recurrent mucocutaneous lesions in the eye that may advance to corneal blindness. Nucleoside analogs exemplified by acyclovir (ACV) form the primary class of antiherpetic drugs, but this class suffers limitations due to the emergence of viral resistance and other side effects. While studying the molecular basis of ocular HSV-1 infection, we observed that BX795, a commonly used inhibitor of TANK-binding kinase 1 (TBK1), strongly suppressed infection by multiple strains of HSV-1 in transformed and primary human cells, cultured human and animal corneas, and a murine model of ocular infection. Our investigations revealed that the antiviral activity of BX795 relies on targeting Akt phosphorylation in infected cells, leading to the blockage of viral protein synthesis. This small-molecule inhibitor, which was also effective against an ACV-resistant HSV-1 strain, shows promise as an alternative to existing drugs and as an effective topical therapy for ocular herpes infection. Collectively, our results obtained using multiple infection models and virus strains establish BX795 as a promising lead compound for broad spectrum antiviral applications in humans. PMID- 29444977 TI - Microenvironmental regulation of the IL-23R/IL-23 axis overrides chronic lymphocytic leukemia indolence. AB - Although the progression of chronic lymphocytic leukemia (CLL) requires the cooperation of the microenvironment, the exact cellular and molecular mechanisms involved are still unclear. We investigated the interleukin (IL)-23 receptor (IL 23R)/IL-23 axis and found that circulating cells from early-stage CLL patients with shorter time-to-treatment, but not of those with a more benign course, expressed a defective form of the IL-23R complex lacking the IL-12Rbeta1 chain. However, cells from both patient groups expressed the complete IL-23R complex in tissue infiltrates and could be induced to express the IL-12Rbeta1 chain when cocultured with activated T cells or CD40L+ cells. CLL cells activated in vitro in this context produced IL-23, a finding that, together with the presence of IL 23 in CLL lymphoid tissues, suggests the existence of an autocrine/paracrine loop inducing CLL cell proliferation. Interference with the IL-23R/IL-23 axis using an anti-IL-23p19 antibody proved effective in controlling disease onset and expansion in xenografted mice, suggesting potential therapeutic strategies. PMID- 29444979 TI - Irreversible inhibition of cytosolic thioredoxin reductase 1 as a mechanistic basis for anticancer therapy. AB - Cancer cells adapt to their inherently increased oxidative stress through activation of the glutathione (GSH) and thioredoxin (TXN) systems. Inhibition of both of these systems effectively kills cancer cells, but such broad inhibition of antioxidant activity also kills normal cells, which is highly unwanted in a clinical setting. We therefore evaluated targeting of the TXN pathway alone and, more specifically, selective inhibition of the cytosolic selenocysteine containing enzyme TXN reductase 1 (TXNRD1). TXNRD1 inhibitors were discovered in a large screening effort and displayed increased specificity compared to pan TXNRD inhibitors, such as auranofin, that also inhibit the mitochondrial enzyme TXNRD2 and additional targets. For our lead compounds, TXNRD1 inhibition correlated with cancer cell cytotoxicity, and inhibitor-triggered conversion of TXNRD1 from an antioxidant to a pro-oxidant enzyme correlated with corresponding increases in cellular production of H2O2 In mice, the most specific TXNRD1 inhibitor, here described as TXNRD1 inhibitor 1 (TRi-1), impaired growth and viability of human tumor xenografts and syngeneic mouse tumors while having little mitochondrial toxicity and being better tolerated than auranofin. These results display the therapeutic anticancer potential of irreversibly targeting cytosolic TXNRD1 using small molecules and present potent and selective TXNRD1 inhibitors. Given the pronounced up-regulation of TXNRD1 in several metastatic malignancies, it seems worthwhile to further explore the potential benefit of specific irreversible TXNRD1 inhibitors for anticancer therapy. PMID- 29444980 TI - Circulating TFH cells, serological memory, and tissue compartmentalization shape human influenza-specific B cell immunity. AB - Immunization with the inactivated influenza vaccine (IIV) remains the most effective strategy to combat seasonal influenza infections. IIV activates B cells and T follicular helper (TFH) cells and thus engenders antibody-secreting cells and serum antibody titers. However, the cellular events preceding generation of protective immunity in humans are inadequately understood. We undertook an in depth analysis of B cell and T cell immune responses to IIV in 35 healthy adults. Using recombinant hemagglutinin (rHA) probes to dissect the quantity, phenotype, and isotype of influenza-specific B cells against A/California09-H1N1, A/Switzerland-H3N2, and B/Phuket, we showed that vaccination induced a three pronged B cell response comprising a transient CXCR5-CXCR3+ antibody-secreting B cell population, CD21hiCD27+ memory B cells, and CD21loCD27+ B cells. Activation of circulating TFH cells correlated with the development of both CD21lo and CD21hi memory B cells. However, preexisting antibodies could limit increases in serum antibody titers. IIV had no marked effect on CD8+, mucosal-associated invariant T, gammadelta T, and natural killer cell activation. In addition, vaccine-induced B cells were not maintained in peripheral blood at 1 year after vaccination. We provide a dissection of rHA-specific B cells across seven human tissue compartments, showing that influenza-specific memory (CD21hiCD27+) B cells primarily reside within secondary lymphoid tissues and the lungs. Our study suggests that a rational design of universal vaccines needs to consider circulating TFH cells, preexisting serological memory, and tissue compartmentalization for effective B cell immunity, as well as to improve targeting cellular T cell immunity. PMID- 29444982 TI - The unique features of proteins depicting the chicken amniotic fluid. AB - In many amniotes, the amniotic fluid is depicted as a dynamic milieu that participates in the protection of the embryo (cushioning, hydration, and immunity). However, in birds, the protein profile of the amniotic fluid remains unexplored, even though its proteomic signature is predicted to differ compared to human's. In fact, unlike humans, chicken amniotic fluid does not collect excretory products and its protein composition strikingly changes at mid development due to the massive inflow of egg white proteins, which are thereafter swallowed by the embryo to support its growth. Using GeLC-MS/MS and shotgun strategies, we identified 91 non-redundant proteins delineating the chicken amniotic fluid proteome at day 11 of development, before egg white transfer. These proteins were essentially associated with the metabolism of nutrients, immune response and developmental processes. Forty-eight proteins were common to both chicken and human amniotic fluids, including serum albumin, apolipoprotein A1 and alpha-fetoprotein. We further investigated the effective role of the chicken amniotic fluid in innate defense and revealed that it exhibits significant antibacterial activity at day 11 of development. This antibacterial potential is drastically enhanced after egg white transfer, presumably due to lysozyme, avian beta-defensin 11, vitelline membrane outer layer protein 1, and beta-microseminoprotein-like as the most likely antibacterial candidates. Interestingly, several proteins recovered in the chicken amniotic fluid prior and after egg white transfer are uniquely found in birds (ovalbumin and related proteins X and Y, avian beta-defensin 11) or oviparous species (vitellogenins 1 and 2, riboflavin-binding protein). This study provides an integrative overview of the chicken amniotic fluid proteome and opens stimulating perspectives in deciphering the role of the avian egg-specific proteins in embryonic development, including innate immunity. These proteins may constitute valuable biomarkers for poultry production to detect hazardous situations (stress, infection, etc.), that may negatively affect the development of the chicken embryo. PMID- 29444981 TI - Protein Palmitoylation Plays an Important Role in Trichomonas vaginalis Adherence. AB - The flagellated protozoan parasite Trichomonas vaginalis is the etiologic agent of trichomoniasis, the most common non-viral sexually transmitted infection worldwide. As an obligate extracellular pathogen, adherence to epithelial cells is critical for parasite survival within the human host and a better understanding of this process is a prerequisite for the development of therapies to combat infection. In this sense, recent work has shown S-acylation as a key modification that regulates pathogenesis in different protozoan parasites. However, there are no reports indicating whether this post-translational modification is a mechanism operating in T. vaginalis In order to study the extent and function of S-acylation in T. vaginalis biology, we undertook a proteomic study to profile the full scope of S-acylated proteins in this parasite and reported the identification of 363 proteins involved in a variety of biological processes such as protein transport, pathogenesis related and signaling, among others. Importantly, treatment of parasites with the palmitoylation inhibitor 2-bromopalmitate causes a significant decrease in parasite: parasite aggregation as well as adherence to host cells suggesting that palmitoylation could be modifying proteins that are key regulators of Trichomonas vaginalis pathogenesis.

PMID- 29444985 TI - Molecular Pharmacodynamics-Guided Scheduling of Biologically Effective Doses: A Drug Development Paradigm Applied to MET Tyrosine Kinase Inhibitors. AB - The development of molecularly targeted agents has benefited from use of pharmacodynamic markers to identify "biologically effective doses" (BED) below MTDs, yet this knowledge remains underutilized in selecting dosage regimens and in comparing the effectiveness of targeted agents within a class. We sought to establish preclinical proof-of-concept for such pharmacodynamics-based BED regimens and effectiveness comparisons using MET kinase small-molecule inhibitors. Utilizing pharmacodynamic biomarker measurements of MET signaling (tumor pY1234/1235MET/total MET ratio) in a phase 0-like preclinical setting, we developed optimal dosage regimens for several MET kinase inhibitors and compared their antitumor efficacy in a MET-amplified gastric cancer xenograft model (SNU 5). Reductions in tumor pY1234/1235MET/total MET of 95%-99% were achievable with tolerable doses of EMD1214063/MSC2156119J (tepotinib), XL184 (cabozantinib), and XL880/GSK1363089 (foretinib), but not ARQ197 (tivantinib), which did not alter the pharmacodynamic biomarker. Duration of kinase suppression and rate of kinase recovery were specific to each agent, emphasizing the importance of developing customized dosage regimens to achieve continuous suppression of the pharmacodynamic biomarker at the required level (here, >=90% MET kinase suppression). The customized dosage regimen of each inhibitor yielded substantial and sustained tumor regression; the equivalent effectiveness of customized dosage regimens that achieve the same level of continuous molecular target control represents preclinical proof-of-concept and illustrates the importance of proper scheduling of targeted agent BEDs. Pharmacodynamics-guided biologically effective dosage regimens (PD-BEDR) potentially offer a superior alternative to pharmacokinetic guidance (e.g., drug concentrations in surrogate tissues) for developing and making head-to-head comparisons of targeted agents.

PMID- 29444987 TI - Cardiovascular Risk Prediction Functions Underestimate Risk in HIV Infection. AB - BACKGROUND: Cardiovascular disease (CVD) risk is elevated in HIV-infected individuals, with contributions from both traditional and nontraditional risk factors. The accuracy of established CVD risk prediction functions in HIV is uncertain. We sought to assess the performance of 3 established CVD risk prediction functions in a longitudinal cohort of HIV-infected men. METHODS: The FHS (Framingham Heart Study) functions for hard coronary heart disease (FHS CHD) and atherosclerotic CVD (FHS ASCVD) and the American College of Cardiology/American Heart Association ASCVD function were applied to the Partners HIV cohort. Risk scores were calculated between January 1, 2006, and December 31, 2008. Outcomes included CHD (myocardial infarction or coronary death) for the FHS CHD function and ASCVD (myocardial infarction, stroke, or coronary death) for the FHS ASCVD and American College of Cardiology/American Heart Association ASCVD functions. We investigated the accuracy of CVD risk prediction for each function when applied to the HIV cohort using comparison of Cox regression coefficients, discrimination, and calibration. RESULTS: The HIV cohort was comprised of 1272 men followed for a median of 4.4 years. There were 78 (6.1%) ASCVD events; the 5 year incidence rate was 16.4 per 1000 person-years. Discrimination was moderate to poor as indicated by the low c statistic (0.68 for FHS CHD, 0.65 for American College of Cardiology/American Heart Association ASCVD, and 0.67 for FHS ASCVD). Observed CVD risk exceeded the predicted risk for each of the functions in most deciles of predicted risk. Calibration, or goodness of fit of the models, was consistently poor, with significant chi2P values for all functions. Recalibration did not significantly improve model fit. CONCLUSIONS: Cardiovascular risk prediction functions developed for use in the general population are inaccurate in HIV infection and systematically underestimate risk in a cohort of HIV infected men. Development of tailored CVD risk prediction functions incorporating traditional CVD risk factors and HIV-specific factors is likely to result in more accurate risk estimation to guide preventative CVD care.

PMID- 29444988 TI - NMDA-Type Glutamate Receptor Activation Promotes Vascular Remodeling and Pulmonary Arterial Hypertension. AB - BACKGROUND: Excessive proliferation and apoptosis resistance in pulmonary vascular cells underlie vascular remodeling in pulmonary arterial hypertension (PAH). Specific treatments for PAH exist, mostly targeting endothelial dysfunction, but high pulmonary arterial pressure still causes heart failure and death. Pulmonary vascular remodeling may be driven by metabolic reprogramming of vascular cells to increase glutaminolysis and glutamate production. The N-methyl d-aspartate receptor (NMDAR), a major neuronal glutamate receptor, is also expressed on vascular cells, but its role in PAH is unknown. METHODS: We assessed the status of the glutamate-NMDAR axis in the pulmonary arteries of patients with PAH and controls through mass spectrometry imaging, Western blotting, and immunohistochemistry. We measured the glutamate release from cultured pulmonary vascular cells using enzymatic assays and analyzed NMDAR regulation/phosphorylation through Western blot experiments. The effect of NMDAR blockade on human pulmonary arterial smooth muscle cell proliferation was determined using a BrdU incorporation assay. We assessed the role of NMDARs in vascular remodeling associated to pulmonary hypertension, in both smooth muscle specific NMDAR knockout mice exposed to chronic hypoxia and the monocrotaline rat model of pulmonary hypertension using NMDAR blockers. RESULTS: We report glutamate accumulation, upregulation of the NMDAR, and NMDAR engagement reflected by increases in GluN1-subunit phosphorylation in the pulmonary arteries of human patients with PAH. Kv channel inhibition and type A-selective endothelin receptor activation amplified calcium-dependent glutamate release from human pulmonary arterial smooth muscle cell, and type A-selective endothelin receptor and platelet-derived growth factor receptor activation led to NMDAR engagement, highlighting crosstalk between the glutamate-NMDAR axis and major PAH-associated pathways. The platelet-derived growth factor-BB-induced proliferation of human pulmonary arterial smooth muscle cells involved NMDAR activation and phosphorylated GluN1 subunit localization to cell-cell contacts, consistent with glutamatergic communication between proliferating human pulmonary arterial smooth muscle cells via NMDARs. Smooth-muscle NMDAR deficiency in mice attenuated the vascular remodeling triggered by chronic hypoxia, highlighting the role of vascular NMDARs in pulmonary hypertension. Pharmacological NMDAR blockade in the monocrotaline rat model of pulmonary hypertension had beneficial effects on cardiac and vascular remodeling, decreasing endothelial dysfunction, cell proliferation, and apoptosis resistance while disrupting the glutamate-NMDAR pathway in pulmonary arteries. CONCLUSIONS: These results reveal a dysregulation of the glutamate-NMDAR axis in the pulmonary arteries of patients with PAH and identify vascular NMDARs as targets for antiremodeling treatments in PAH. PMID- 29444991 TI - Ozone Generation during High-Voltage Leak Detection: Fiction or Reality? AB - In order to further clarify if and how much ozone is generated during high voltage leak detection and to identify measures to reduce the impact of ozone generation on product quality, a highly sensitive analytical system was employed to investigate the generation of ozone at different operational conditions of high-voltage leak detection integrity testing. The analytical system is based on oxidation of Iodide ions in solution and identification of the Iodine formed by N, N-Diethyl-p-phenylendiamine (DPD) according to DIN 38403. Sensitivity of the system was found suitable to detect ozone levels as low as 0.025 ppm (mg/L). High voltage leak detection process parameters-inspection speed, high voltage, filling level of the ampoule, and exposure time to the ampoule to high voltage-were varied between maximum and minimum values applicable in integrity testing of different ampoule sizes. For variation of exposure time, ampoules were repetitively tested by the leak testing machine to achieve a maximum exposure time of the ampoule up to 24 s (exposure time during production <=2.4 s). No ozone was detected during the study under all inspection conditions. Even repeated exposure of the ampoules to high-voltage leak detection did not result in generation of measurable ozone levels. It has to be concluded that high voltage leak detection is not prone to causing oxidation of the drug products.LAY ABSTRACT: For drug products in ampoules, 100% integrity testing is requested both by European and US regulations. Detection of integrity defects like small holes or cracks in the ampoule can be performed by numerous methods. Due to automation requirements, only three methods have been used during routine production-vacuum decay, head space infrared spectroscopy, and high-voltage leak detection. High voltage leak detection is the most common method used in the pharmaceutical industry for 100% integrity testing of ampoules, but resent publications showed considerable oxidation of an air-sensitive active pharmaceutical ingredient during the integrity testing process. It was assumed that ozone generated in the inside of the vial due to exposure of the product to the high voltage during the testing process may be responsible for this result. As ozone is a very aggressive and non-selective oxidant, this result posed a serious thread not only to this product but also to the quality of many other products subjected to integrity testing by high-voltage leak detection.

The document provides a summary of historical microbiological control concerns, coupled with industry-derived best practices, for material, equipment, and storage controls required to mitigate the potential for microbial ingress and contamination of chromatography resin and equipment.

PMID- 29444993 TI - A Novel Method for Qualification of a Potency Assay through Partial Computer Simulation. AB - For biotherapeutics and vaccines, potency is measured in a bioassay that compares the concentration-response curves of a new batch to that of a reference standard. Acceptable accuracy and precision of potency measurement is critical to the manufacturing of these products. These characteristics of a bioassay are typically assessed in a procedure that is carried out with samples spanning the acceptable range for the product. During early development, however, a full validation study such as that which is carried out in late development can be costly as it relates to the likelihood of eventual program success. For these reasons, the laboratory may look for alternative ways to ensure the validity of the bioassay across a range that will support product development. One such alternative combines information from a reduced procedure using only reference standard and 100% relative potency concentration-response data sets, together with computer simulation, to estimate missing relative potency values across the desired range. Fits to the reduced dataset provide estimates of bioassay model parameters such as those for an S-shaped potency assay that follows a four parameter logistic relationship, along with estimates of their variance covariance structure and independent experimental unit (e.g., well-to-well or animal-to-animal) errors. Using Bayesian Markov Chain Monte Carlo modeling, the predictive distribution of the concentration-response data for the desired levels of relative potency is generated. Results from use of the reduced procedure are compared to results calculated from a full dataset in Monte Carlo simulation and in a motivating example.LAY ABSTRACT: For biotherapeutics and vaccines, potency is measured in a bioassay that compares the concentration-response curves of a new batch to that of a reference standard.

PMID- 29444994 TI - Life Cycle Assessment of Reusable and Disposable Cleanroom Coveralls. AB - Cleanroom garments serve a critical role in such industries as pharmaceuticals, life sciences, and semiconductor manufacturing. These textiles are available in reusable and disposable alternatives. In this report, the environmental sustainability of cleanroom coveralls is examined using life cycle assessment technology. The complete supply chain, manufacture, use, and end-of-life phases for reusable and disposable cleanroom coveralls are compared on a cradle-to-end of-life cycle basis. Three industry representative coveralls are examined: a reusable woven polyethylene terephthalate (PET) coverall, a disposable flash spunbonded high-density polyethylene (HDPE) coverall, and a disposable spunbond meltblown-spunbond polypropylene (SMS PP) coverall. The reusable cleanroom coverall system shows substantial improvements over both disposable cleanroom coverall systems in all environmental impact categories. The improvements over the disposable HDPE coverall were 34% lower process energy (PE), 23% lower natural resource energy (NRE), 27% lower greenhouse gas (GHG) emissions, and 73% lower blue water consumption. The improvements over the disposable SMS PP coverall were 59% lower PE, 56% lower NRE, 57% lower GHG emissions, and 77% lower blue water consumption. In addition, the reusable system shows a 94-96% reduction in solid waste to the landfill from the cleanroom facility. Between the two disposable cleanroom coveralls, the flash spunbonded HDPE coverall shows a measurable environmental improvement over the SMS PP coverall.LAY ABSTRACT: Pharmaceutical drugs are manufactured and handled in controlled environments called cleanrooms to ensure the safety and quality of products. In order to maintain strict levels of cleanliness, cleanroom personnel are required to wear garments such as coveralls, hoods, and gloves that restrict the transfer of particles from the person to the environment. These garments are available in reusable and disposable types. Cleanroom operators consider a number of factors when selecting between reusable and disposable garments, including price, comfort, and environmental sustainability.In this report, the environmental sustainability of reusable and disposable cleanroom coveralls is examined using a technique called life cycle assessment. With this technique, environmental parameters such as energy use and greenhouse gas emissions are quantified and compared for three market representative cleanroom coveralls, from raw material extraction through manufacturing, use, and final disposal. Reusable coveralls were found to substantially outperform disposable coveralls in all environmental parameters examined. This is an important conclusion that supports cleanroom companies that select reusable coveralls to be more sustainable. PMID- 29444995 TI - PDA Points to Consider: Best Practices for Document/Data Management and Control and Preparing for Data Integrity Inspections. AB - The Parenteral Drug Association (PDA) has identified 11 current questions related to data management and control that have been frequently cited in U.S. Food and Drug Administration (FDA) inspections or have led to FDA regulatory actions. The purpose of this document is to help to clarify some of these issues for industry and to help facilitate better compliance by sharing PDA members' expertise in and understanding of current best practices.Data integrity inspectional observations by health authorities can have a severe impact on a firm from a regulatory and public perception perspective and should not result from a lack of clarity by industry about what is required. In addition, firms are concerned that the inability to produce a requested record or document during an inspection, even if not a standard report or existing quality system document, could be construed as delaying, denying, limiting, or refusing inspection, which also has significant consequences.The PDA acknowledges it may not be possible for a single firm or site to have a meaningful discussion of these issues in the context of an inspection or inspection response and is offering these best practices so that industry can proactively comply and properly prioritize its efforts to improve document management and control and good manufacturing practices in the most efficient and effective means possible. The PDA acknowledges there are many more questions to be addressed and hopes that there can be an ongoing dialogue between industry and regulators to facilitate answers. PMID- 29444996 TI - A Model of Risk Analysis in Analytical Methodology for Biopharmaceutical Quality Control. AB - One key quality control parameter for biopharmaceutical products is the analysis of residual cellular DNA. To determine small amounts of DNA (around 100 pg) that may be in a biologically derived drug substance, an analytical method should be sensitive, robust, reliable, and accurate. In principle, three techniques have the ability to measure residual cellular DNA: radioactive dot-blot, a type of hybridization; threshold analysis; and quantitative polymerase chain reaction. Quality risk management is a systematic process for evaluating, controlling, and reporting of risks that may affects method capabilities and supports a scientific and practical approach to decision making. This paper evaluates, by quality risk management, an alternative approach to assessing the performance risks associated with quality control methods used with biopharmaceuticals, using the tool hazard analysis and critical control points. This tool provides the possibility to find the steps in an analytical procedure with higher impact on method performance. By applying these principles to DNA analysis methods, we conclude that the radioactive dot-blot assay has the largest number of critical control points, followed by quantitative polymerase chain reaction, and threshold analysis. From the analysis of hazards (i.e., points of method failure) and the associated method procedure critical control points, we conclude that the analytical methodology with the lowest risk for performance failure for residual cellular DNA testing is quantitative polymerase chain reaction.LAY ABSTRACT: In order to mitigate the risk of adverse events by residual cellular DNA that is not completely cleared from downstream production processes, regulatory agencies have required the industry to guarantee a very low level of DNA in biologically derived pharmaceutical products. The technique historically used was radioactive blot hybridization. However, the technique is a challenging method to implement in a quality control laboratory: It is laborious, time consuming, semi quantitative, and requires a radioisotope. Along with dot-blot hybridization, two alternatives techniques were evaluated: threshold analysis and quantitative polymerase chain reaction. Quality risk management tools were applied to compare the techniques, taking into account the uncertainties, the possibility of circumstances or future events, and their effects upon method performance. By illustrating the application of these tools with DNA methods, we provide an example of how they can be used to support a scientific and practical approach to decision making and can assess and manage method performance risk using such tools. This paper discusses, considering the principles of quality risk management, an additional approach to the development and selection of analytical quality control methods using the risk analysis tool hazard analysis and critical control points. This tool provides the possibility to find the method procedural steps with higher impact on method reliability (called critical control points). Our model concluded that the radioactive dot-blot assay has the larger number of critical control points, followed by quantitative polymerase chain reaction and threshold analysis. Quantitative polymerase chain reaction is shown to be the better alternative analytical methodology in residual cellular DNA analysis. PMID- 29444997 TI - Efficacy of multicomponent culturally tailored HIV/ STI prevention interventions targeting foreign female entertainment workers: a quasi-experimental trial. AB - OBJECTIVES: We assessed the efficacy of a multicomponent culturally tailored HIV/STI prevention intervention programme on consistent condom use and STI incidence among foreign Thai and Vietnamese female entertainment workers (FEWs) in Singapore. METHODS: We conducted a quasi-experimental pretest and post-test intervention trial with a comparison group. We recruited 220 participants (115 Vietnamese and 105 Thai) for the comparison group, followed by the intervention group (same number) from the same sites which were purposively selected after a 3 month interval period. Both groups completed a self-administered anonymous questionnaire and STI testing for cervical gonorrhoea and Chlamydia, as well as pharyngeal gonorrhoea at baseline and 6-week follow-up. The peer-led intervention consisted of behavioural (HIV/STI education and condom negotiation skills), biomedical (STI screening and treatment services) and structural components (access to free condoms). We used the mixed effects Poisson regression model accounting for clustering by establishment venue to compute the adjusted risk ratio (aRR) of the outcomes at follow-up. RESULTS: At follow-up, the intervention group was more likely than the comparison group to report consistent condom use for vaginal sex with paid (aRR 1.77; 95% CI 1.71 to 1.83) and casual (aRR 1.81; 95% CI 1.71 to 1.91) partners. For consistent condom use for oral sex, this was aRR 1.50; 95% CI 1.23 to 1.82 with paid and aRR 1.54; 95% CI 1.22 to 1.95 with casual partners. STI incidence at follow-up was significantly lower in the intervention (6.8 per 100 FEWs) than the comparison (14.8 per 100 FEWs) group (aRR 0.42; 95% CI 0.32 to 0.55). CONCLUSIONS: This trial was effective in promoting consistent condom use for vaginal and oral sex as well as reducing STI incidence among the foreign Thai and Vietnamese FEWs in Singapore. The feasibility of scaling up the interventions to all entertainment establishments in Singapore should be assessed.

PMID- 29444998 TI - Treatment of Aortic Stenosis With a Self-Expanding, Resheathable Transcatheter Valve: One-Year Results of the International Multicenter Portico Transcatheter Aortic Valve Implantation System Study. AB - BACKGROUND: The aim of the Portico TAVI (transcatheter aortic valve implantation) system study was to evaluate outcomes <=1 year after implantation of a novel resheathable, self-expanding TAVI system in a multicenter patient population with severe aortic stenosis (AS). METHODS AND RESULTS: High-risk patients (n=222) with symptomatic severe AS (mean age, 83.0+/-4.6 years; 74.3% women) were enrolled across 12 centers in Europe and Australia. The study's primary end point was all cause mortality at 30 days. A total of 209 patients who received the Portico TAVI system were available for follow-up after the 30-day visit. Data collection included hemodynamic assessment by echocardiography with core laboratory evaluation and assessment of functional status. Valve Academic Research Consortium-defined adverse events were adjudicated by an independent Clinical Events Committee. TAVI using the Portico valve led to a significant and persistent improvement in aortic valve function at 1 year. More than mild paravalvular leak was present in 5.7% and 7.5% of patients at 30 days and 1 year, respectively. Kaplan-Meier estimates at 30 days and 1 year were 3.6% and 13.8% for all-cause mortality, 3.6% and 9.6% for cardiovascular mortality, and 3.2% and 5.8% for major (disabling) stroke. After 30 days and <=1 year of follow-up, adverse events included stage 3 acute kidney injury (n=3), major vascular complications (n=5), and life-threatening/disabling bleeding (n=3). Overall permanent pacemaker rate was 14.7%. At 1 year, 74.8% improved >=1 New York Heart Association class compared with baseline (P<0.0001). CONCLUSIONS: The Portico TAVI system is safe and effective at 1 year, yielding low mortality and stroke rates in high-risk patients with severe AS.

PMID- 29445000 TI - Retroperitoneal Hemorrhage After Percutaneous Coronary Intervention: Incidence, Determinants, and Outcomes as Recorded by the British Cardiovascular Intervention Society. AB - BACKGROUND: Retroperitoneal hemorrhage (RH) is a rare bleeding complication of percutaneous coronary intervention, which can result as a consequence of femoral access or can occur spontaneously. This study aims to evaluate temporal changes in RH, its predictors, and clinical outcomes in a national cohort of patients undergoing percutaneous coronary intervention in the United Kingdom. METHODS AND RESULTS: We analyzed RH events in patients who underwent percutaneous coronary intervention between 2007 and 2014. Multiple logistic regression models were used to identify factors associated with RH and to quantify the association between RH and 30-day mortality and major adverse cardiovascular events. A total of 511 106 participants were included, and 291 in hospital RH events were recorded (0.06%). Overall, rates of RH declined from 0.09% to 0.03% between 2007 and 2014. The strongest independent predictors of RH events were femoral access (odds ratio [OR], 19.66; 95% confidence interval [CI], 11.22-34.43), glycoprotein IIb/IIIa inhibitor (OR, 2.63; 95% CI, 1.99-3.47), and warfarin use (OR, 2.53; 95% CI, 1.07 5.99). RH was associated with a significant increase in 30-day mortality (OR, 3.59; 95% CI, 2.19-5.90) and in-hospital major adverse cardiovascular events (OR, 5.76; 95% CI, 3.71-8.95). A legacy effect was not observed; patients with RH who survived 30 days did not have higher 1-year mortality compared with those without this complication (hazard ratio, 0.97; 95% CI, 0.49-1.91). CONCLUSIONS: Our results suggest that RH is a rare event that is declining in the United Kingdom, related to transition to transradial access site utilization, but remains a clinically important event associated with increased 30-day mortality but no long term legacy effect. PMID- 29445001 TI - Interventional Treatment of Severe Tricuspid Regurgitation: Early Clinical Experience in a Multicenter, Observational, First-in-Man Study. AB - BACKGROUND: Transcatheter caval valve implantation is under evaluation as a treatment option for inoperable patients with severe tricuspid regurgitation (TR). The procedure involves the catheter-based implantation of bioprosthetic valves in the inferior vena cava and superior vena cava to treat symptoms associated with TR. This study is the first to evaluate the feasibility, safety, and efficacy of this interventional concept. METHODS AND RESULTS: Twenty-five patients (mean age, 73.9+/-7.6 years; women, 52.0%) with severe symptomatic TR despite optimal medical treatment deemed unsuitable for surgery were treated with caval valve implantation under a compassionate clinical use program. Technical feasibility defined as procedural success, hemodynamic effect defined as venous pressure reduction, and safety defined as periprocedural adverse events were evaluated, with clinical follow-up at discharge and up to 12 months. The functional impact was evaluated by assessment of New York Heart Association class at the time of hospital discharge. The total number of valves implanted in the caval position was 31. Patients were treated with single (inferior vena cava only; n=19; 76.0%) or bicaval valve implantation (inferior vena cava+superior vena cava; n=6; 24.0%). Either balloon-expandable valves (Sapien XT/3: n=18; 72.0%) or self-expandable valves (TricValve: n=6; 24.0%; Directflow: n=1; 4.0%) were used. Procedural success was achieved in 96% (n=24). Early and late valve migration requiring surgical intervention occurred in 1 patient each. Thirty-day and in-hospital mortality were 8% (2 of 25) and 16% (4 of 25). Causes of in hospital mortality included respiratory (n=1) or multiple organ failure (n=3) and were not linked to the procedure. Mean overall survival in the study cohort was 316+/-453 days (14-1540 days). CONCLUSIONS: Caval valve implantation for the treatment of severe TR and advanced right ventricular failure is associated with a high procedural success rate and seems safe and feasible in an excessive-risk cohort. The study demonstrates hemodynamic efficacy with consistent elimination of TR-associated venous backflow and initial clinical improvement. These results encourage further trials to determine which patients benefit most from this interventional approach.

PMID- 29445006 TI - Inflammatory Monocytes Drive Influenza A Virus-Mediated Lung Injury in Juvenile Mice. AB - Healthy children are more likely to die of influenza A virus (IAV) infection than healthy adults. However, little is known about the mechanisms underlying the impact of young age on the development of life-threatening IAV infection. We report increased mortality in juvenile mice compared with adult mice at each infectious dose of IAV. Juvenile mice had sustained elevation of type I IFNs and persistent NLRP3 inflammasome activation in the lungs, both of which were independent of viral titer. Juvenile mice, but not adult mice, had increased MCP 1 levels that remained high even after viral clearance. Importantly, continued production of MCP-1 was associated with persistent recruitment of monocytes to the lungs and prolonged elevation of inflammatory cytokines. Transcriptional signatures of recruited monocytes to the juvenile and adult IAV-infected lungs were assessed by RNA-seq. Genes associated with a proinflammatory signature were upregulated in the juvenile monocytes compared with adult monocytes. Depletion of monocytes with anti-CCR2 Ab decreased type I IFN secretion, NLRP3 inflammasome activation, and lung injury in juvenile mice. This suggests an exaggerated inflammatory response mediated by increased recruitment of monocytes to the lung, and not an inability to control viral replication, is responsible for severe IAV infection in juvenile mice. This study provides insight into severe IAV infection in juveniles and identifies key inflammatory monocytes that may be central to pediatric acute lung injury secondary to IAV. PMID- 29445007 TI - Highly Efficient and Versatile Plasmid-Based Gene Editing in Primary T Cells. AB - Adoptive cell transfer is an important approach for basic research and emerges as an effective treatment for various diseases, including infections and blood cancers. Direct genetic manipulation of primary immune cells opens up unprecedented research opportunities and could be applied to enhance cellular therapeutic products. In this article, we report highly efficient genome engineering in primary murine T cells using a plasmid-based RNA-guided CRISPR system. We developed a straightforward approach to ablate genes in up to 90% of cells and to introduce precisely targeted single nucleotide polymorphisms in up to 25% of the transfected primary T cells. We used gene editing-mediated allele switching to quantify homology-directed repair, systematically optimize experimental parameters, and map a native B cell epitope in primary T cells. Allele switching of a surrogate cell surface marker can be used to enrich cells, with successful simultaneous editing of a second gene of interest. Finally, we applied the approach to correct two disease-causing mutations in the Foxp3 gene. Repairing the cause of the scurfy syndrome, a 2-bp insertion in Foxp3, and repairing the clinically relevant Foxp3K276X mutation restored Foxp3 expression in primary T cells. PMID- 29445008 TI - Blockade of Host beta2-Adrenergic Receptor Enhances Graft-versus-Tumor Effect through Modulating APCs. AB - Allogeneic hematopoietic cell transplantation is a potential curative therapy for hematologic malignancies. Host APCs are pivotal to the desired graft-versus-tumor (GVT) effect. Recent studies have shown that beta2-adrenergic receptor (beta2AR) signaling can have an important impact on immune cell function, including dendritic cells (DCs). In this article, we demonstrate that pretreatment of host mice with a beta2AR blocker significantly increases the GVT effect of donor CD8+ T cells by decreasing tumor burden without increasing graft-versus-host disease. beta2AR-deficient host mice have significantly increased effector memory and central memory CD8+ T cells and improved reconstitution of T cells, including CD4+Foxp3+ regulatory T cells. Notably, beta2AR deficiency induces increased CD11c+ DC development. Also, beta2AR-deficient bone marrow-derived DCs induce higher CD8+ T cell proliferation and improved tumor killing in vitro. Metabolic profiling shows that beta2AR deficiency renders DCs more immunogenic through upregulation of mTOR activity and reduction of STAT3 phosphorylation. Altogether, these findings demonstrate an important role for host beta2AR signaling in suppressing T cell reconstitution and GVT activity. PMID- 29445009 TI - Human Binge Alcohol Intake Inhibits TLR4-MyD88 and TLR4-TRIF Responses but Not the TLR3-TRIF Pathway: HspA1A and PP1 Play Selective Regulatory Roles. AB - Binge/moderate alcohol suppresses TLR4-MyD88 proinflammatory cytokines; however, alcohol's effects on TLR-TRIF signaling, especially after in vivo exposure in humans, are unclear. We performed a comparative analysis of the TLR4-MyD88, TLR4 TRIF, and TLR3-TRIF pathways in human monocytes following binge alcohol exposure. Mechanistic regulation of TLR-TRIF signaling by binge alcohol was evaluated by analyzing IRF3 and TBK1, upstream regulator protein phosphatase 1 (PP1), and immunoregulatory stress proteins HspA1A and XBP-1 in alcohol-treated human and mouse monocytes/macrophages. Two approaches for alcohol exposure were used: in vivo exposure of primary monocytes in binge alcohol-consuming human volunteers or in vitro exposure of human monocytes/murine macrophages to physiological alcohol concentrations (25-50 mM ethanol), followed by LPS (TLR4) or polyinosinic polycytidylic acid (TLR3) stimulation ex vivo. In vivo and in vitro binge alcohol exposure significantly inhibited the TLR4-MyD88 cytokines TNF-alpha and IL-6, as well as the TLR4-TRIF cytokines/chemokines IFN-beta, IP-10, and RANTES, in human monocytes, but not TLR3-TRIF-induced cytokines/chemokines, as detected by quantitative PCR and ELISA. Mechanistic analyses revealed TBK-1-independent inhibition of the TLR4-TRIF effector IRF3 in alcohol-treated macrophages. Although stress protein XBP-1, which is known to regulate IRF3-mediated IFN-beta induction, was not affected by alcohol, HspA1A was induced by in vivo alcohol in human monocytes. Alcohol-induced HspA1A was required for inhibition of TLR4-MyD88 signaling but not TLR4-TRIF cytokines in macrophages. In contrast, inhibition of PP1 prevented alcohol-mediated TLR4-TRIF tolerance in macrophages. Collectively, our results demonstrate that in vivo and in vitro binge alcohol exposure in humans suppresses TLR4-MyD88 and TLR4-TRIF, but not TLR3-TRIF, responses. Whereas alcohol-mediated effects on the PP1-IRF3 axis inhibit the TLR4-TRIF pathway, HspA1A selectively suppresses the TLR4-MyD88 pathway in monocytes/macrophages.

AB - Small animal veterinarians' opinions were investigated regarding the frequency and nature of ethical dilemmas encountered, beliefs regarding euthanasia and balancing client and animal interests, prevalence and value of ethics training and proposals to mitigate the stressful effects of ethical dilemmas. The majority (52 per cent) of 484 respondents in the USA indicated via an online survey experiencing an ethical dilemma regarding the interests of clients and those of their patients at least weekly. Scenarios involving client financial concerns were commonly reported causes of ethical conflicts. While only 20 per cent of respondents indicated that other practitioners prioritise patient interests, 50 per cent of respondents characterised their own behaviour as prioritising patients. Most respondents (52 per cent) reported that ethical dilemmas are the leading cause, or are one of many equal causes, of work-related stress. Less experienced practitioners, general practitioners and associate veterinarians were more likely to encounter situations they defined as ethical dilemmas, and female respondents were more likely to find ethical dilemmas stressful. Most small animal veterinarians experience ethical dilemmas regularly, which contribute to moral stress. Results suggested that most small animal practitioners believe that greater awareness of moral stress and providing training in ethical theories and tools for coping with ethical dilemmas can ameliorate moral stress. PMID- 29445011 TI - Understanding veterinary leadership in practice. AB - The Vet Futures Report has identified 'exceptional leadership' as a key ambition for the long-term sustainability of the industry. This research investigates what it is like to be a veterinary surgeon in an in-practice leadership position, applying the qualitative methodology of interpretative phenomenological analysis. Through the researchers' interpretation of the seven participants' stories of their leadership experiences, the study advances understanding of the work environment, underlying motivations and the perceived responsibilities of veterinary leaders. Findings suggest, for many, a struggle in transition to leader positions, improving with time. The increase in pace of work is relayed by participants, with an ongoing, and unchallenged, work-life imbalance. The vets involved are highly motivated, driven by enjoyment of their jobs, a desire for self-determination and a need to make a difference. Relationships form the core of the perceived responsibilities, and yet are identified as the greatest day-to day challenge of leadership. This study offers a valuable insight for veterinary surgeons, suggesting the industry could benefit from pausing and reflecting on behaviours. With a greater understanding of the complexity of leadership and followership, progress can be made to enact positive changes for the future. PMID- 29445012 TI - Counterintuitive increase in observed Mycobacterium avium subspecies paratuberculosis prevalence in sympatric rabbits following the introduction of paratuberculosis control measures in cattle. AB - Paratuberculosis (Johne's disease) is caused by the bacterium Mycobacterium avium subspecies paratuberculosis (Map). Achieving herd-level control of mycobacterial infection is notoriously difficult, despite widespread adoption of test-and-cull based control strategies. The presence of infection in wildlife populations could be contributing to this difficulty. Rabbits are naturally infected with the same Map strain as cattle, and can excrete high levels in their faeces. The aim of this study is to determine if implementation of paratuberculosis control in cattle leads to a decline in Map infection levels in rabbits. An island-wide, test-and-cull-based paratuberculosis control programme was initiated on a Scottish island in 2008. In this study annual tests were obtained from 15 cattle farms, from 2008 to 2011, totalling 2609 tests. Rabbits (1564) were sampled from the 15 participating farms, from 2008 to 2011, and Map was detected by faecal culture. Map seroprevalence in cattle decreased from 16 to 7.2 per cent, while Map prevalence in rabbits increased from 10.3 to 20.3 per cent. Results indicate that efforts to control paratuberculosis in cattle do not reduce Map levels in sympatric rabbits. This adds to mounting evidence that if Map becomes established in wild rabbit populations, rabbits represent a persistent and widespread source of infection, potentially impeding livestock control strategies.

PMID- 29445014 TI - Effect of on-farm interventions in the aftermath of an outbreak of hypervirulent verocytotoxin-producing Escherichia coli O157:H7 in Sweden. AB - In 2007, human infections with a hypervirulent strain of verocytotoxin-producing Escherichia coli O157:H7 increased in Sweden and especially in the Halland County. A connection between the cases and a local beef cattle farm with an on farm abattoir and meat processing plant was established. In this observational study the control measures implemented on the infected farm and the dynamics of infection in the herd are described. In May 2008, when measures were initiated and animals put to pasture, the prevalence of positive individuals was 40 per cent and 18 carcasses out of 24 slaughtered animals were contaminated. During summer the monthly prevalence of positive carcasses varied between 8 and 41 per cent and at turning-in 22 out of 258 individually sampled animals were shedding the pathogen. After January 2009 no positive carcasses were found at slaughter and follow-up samplings of environment and individuals remained negative until the study period ended in May 2010. The results indicate that on-farm measures have potential to reduce the prevalence of the pathogen in a long-term perspective. However, as self-clearance cannot be excluded the effectiveness of the suggested measures needs to be confirmed. PMID- 29445015 TI - Influence of ageing on quantitative contrast-enhanced ultrasound of the kidneys in healthy cats. AB - The degenerative effects of ageing on the kidneys have been extensively studied in humans. However, only recently interest has been focused on renal ageing in veterinary medicine. Contrast-enhanced ultrasound allows non-invasive evaluation of renal perfusion in conscious cats. Renal perfusion parameters were obtained in 43 healthy cats aged 1-16 years old, and the cats were divided in four age categories: 1-3 years, 3-6 years, 6-10 years and over 10 years. Routine renal parameters as serum creatinine, serum urea, urine-specific gravity, urinary protein:creatinine ratio and systolic blood pressure were also measured. No significant differences in any of the perfusion parameters were observed among the different age categories. A trend towards a lower peak enhancement and wash in area under the curve with increasing age, suggestive for a lower blood volume, was detected when comparing the cats over 10 years old with the cats of 1-3 years old. Additionally, no significant age-effect was observed for the serum and urine parameters, whereas a higher blood pressure was observed in healthy cats over 10 years old.

AB - Shipping is the dominant marine anthropogenic noise source in the world's oceans, yet we know little about vessel encounter rates, exposure levels and behavioural reactions for cetaceans in the wild, many of which rely on sound for foraging, communication and social interactions. Here, we used animal-borne acoustic tags to measure vessel noise exposure and foraging efforts in seven harbour porpoises in highly trafficked coastal waters. Tagged porpoises encountered vessel noise 17 89% of the time and occasional high-noise levels coincided with vigorous fluking, bottom diving, interrupted foraging and even cessation of echolocation, leading to significantly fewer prey capture attempts at received levels greater than 96 dB re 1 uPa (16 kHz third-octave). If such exposures occur frequently, porpoises, which have high metabolic requirements, may be unable to compensate energetically with negative long-term fitness consequences. That shipping noise disrupts foraging in the high-frequency-hearing porpoise raises concerns that other toothed whale species may also be affected. PMID- 29445017 TI - Landscape configurational heterogeneity by small-scale agriculture, not crop diversity, maintains pollinators and plant reproduction in western Europe. AB - Agricultural intensification is one of the main causes for the current biodiversity crisis. While reversing habitat loss on agricultural land is challenging, increasing the farmland configurational heterogeneity (higher field border density) and farmland compositional heterogeneity (higher crop diversity) has been proposed to counteract some habitat loss. Here, we tested whether increased farmland configurational and compositional heterogeneity promote wild pollinators and plant reproduction in 229 landscapes located in four major western European agricultural regions. High-field border density consistently increased wild bee abundance and seed set of radish (Raphanus sativus), probably through enhanced connectivity. In particular, we demonstrate the importance of crop-crop borders for pollinator movement as an additional experiment showed higher transfer of a pollen analogue along crop-crop borders than across fields or along semi-natural crop borders. By contrast, high crop diversity reduced bee abundance, probably due to an increase of crop types with particularly intensive management. This highlights the importance of crop identity when higher crop diversity is promoted. Our results show that small-scale agricultural systems can boost pollinators and plant reproduction. Agri-environmental policies should therefore aim to halt and reverse the current trend of increasing field sizes and to reduce the amount of crop types with particularly intensive management. PMID- 29445019 TI - Wound treatment and selective help in a termite-hunting ant. AB - Open wounds are a major health risk in animals, with species prone to injuries likely developing means to reduce these risks. We therefore analysed the behavioural response towards open wounds on the social and individual level in the termite group-hunting ant Megaponera analis During termite raids, some ants get injured by termite soldiers (biting off extremities), after the fight injured ants get carried back to the nest by nest-mates. We observed treatment of the injury by nest-mates inside the nest through intense allogrooming at the wound. Lack of treatment increased mortality from 10% to 80% within 24 h, most likely due to infections. Wound clotting occurred extraordinarily fast in untreated injured individuals, within 10 min. Furthermore, heavily injured ants (loss of five extremities) were not rescued or treated; this was regulated not by the helper but by the unresponsiveness of the injured ant. Interestingly, lightly injured ants behaved 'more injured' near nest-mates. We show organized social wound treatment in insects through a multifaceted help system focused on injured individuals. This was not only limited to selective rescuing of lightly injured individuals by carrying them back (thus reducing predation risk), but, moreover, included a differentiated treatment inside the nest. PMID- 29445020 TI - Trade-offs between microbial growth phases lead to frequency-dependent and non transitive selection. AB - Mutations in a microbial population can increase the frequency of a genotype not only by increasing its exponential growth rate, but also by decreasing its lag time or adjusting the yield (resource efficiency). The contribution of multiple life-history traits to selection is a critical question for evolutionary biology as we seek to predict the evolutionary fates of mutations. Here we use a model of microbial growth to show that there are two distinct components of selection corresponding to the growth and lag phases, while the yield modulates their relative importance. The model predicts rich population dynamics when there are trade-offs between phases: multiple strains can coexist or exhibit bistability due to frequency-dependent selection, and strains can engage in rock-paper scissors interactions due to non-transitive selection. We characterize the environmental conditions and patterns of traits necessary to realize these phenomena, which we show to be readily accessible to experiments. Our results provide a theoretical framework for analysing high-throughput measurements of microbial growth traits, especially interpreting the pleiotropy and correlations between traits across mutants. This work also highlights the need for more comprehensive measurements of selection in simple microbial systems, where the concept of an ordinary fitness landscape breaks down. PMID- 29445021 TI - The influence of the few: a stable 'oligarchy' controls information flow in house hunting ants. AB - Animals that live together in groups often face difficult choices, such as which food resource to exploit, or which direction to flee in response to a predator. When there are costs associated with deadlock or group fragmentation, it is essential that the group achieves a consensus decision. Here, we study consensus formation in emigrating ant colonies faced with a binary choice between two identical nest-sites. By individually tagging each ant with a unique radio frequency identification microchip, and then recording all ant-to-ant 'tandem runs'-stereotyped physical interactions that communicate information about potential nest-sites-we assembled the networks that trace the spread of consensus throughout the colony. Through repeated emigrations, we show that both the order in which these networks are assembled and the position of each individual within them are consistent from emigration to emigration. We demonstrate that the formation of the consensus is delegated to an influential but exclusive minority of highly active individuals-an 'oligarchy'-which is further divided into two subgroups, each specialized upon a different tandem running role. Finally, we show that communication primarily occurs between subgroups not within them, and further, that such between-group communication is more efficient than within group communication. PMID- 29445022 TI - Whole genome duplication and transposable element proliferation drive genome expansion in Corydoradinae catfishes. AB - Genome size varies significantly across eukaryotic taxa and the largest changes are typically driven by macro-mutations such as whole genome duplications (WGDs) and proliferation of repetitive elements. These two processes may affect the evolutionary potential of lineages by increasing genetic variation and changing gene expression. Here, we elucidate the evolutionary history and mechanisms underpinning genome size variation in a species-rich group of Neotropical catfishes (Corydoradinae) with extreme variation in genome size-0.6 to 4.4 pg per haploid cell. First, genome size was quantified in 65 species and mapped onto a novel fossil-calibrated phylogeny. Two evolutionary shifts in genome size were identified across the tree-the first between 43 and 49 Ma (95% highest posterior density (HPD) 36.2-68.1 Ma) and the second at approximately 19 Ma (95% HPD 15.3 30.14 Ma). Second, restriction-site-associated DNA (RAD) sequencing was used to identify potential WGD events and quantify transposable element (TE) abundance in different lineages. Evidence of two lineage-scale WGDs was identified across the phylogeny, the first event occurring between 54 and 66 Ma (95% HPD 42.56-99.5 Ma) and the second at 20-30 Ma (95% HPD 15.3-45 Ma) based on haplotype numbers per contig and between 35 and 44 Ma (95% HPD 30.29-64.51 Ma) and 20-30 Ma (95% HPD 15.3-45 Ma) based on SNP read ratios. TE abundance increased considerably in parallel with genome size, with a single TE-family (TC1-IS630-Pogo) showing several increases across the Corydoradinae, with the most recent at 20-30 Ma (95% HPD 15.3-45 Ma) and an older event at 35-44 Ma (95% HPD 30.29-64.51 Ma). We identified signals congruent with two WGD duplication events, as well as an increase in TE abundance across different lineages, making the Corydoradinae an excellent model system to study the effects of WGD and TEs on genome and organismal evolution. PMID- 29445023 TI - Ocean acidification but not warming alters sex determination in the Sydney rock oyster, Saccostrea glomerata. AB - Whether sex determination of marine organisms can be altered by ocean acidification and warming during this century remains a significant, unanswered question. Here, we show that exposure of the protandric hermaphrodite oyster, Saccostrea glomerata to ocean acidification, but not warming, alters sex determination resulting in changes in sex ratios. After just one reproductive cycle there were 16% more females than males. The rate of gametogenesis, gonad area, fecundity, shell length, extracellular pH and survival decreased in response to ocean acidification. Warming as a sole stressor slightly increased the rate of gametogenesis, gonad area and fecundity, but this increase was masked by the impact of ocean acidification at a level predicted for this century. Alterations to sex determination, sex ratios and reproductive capacity will have flow on effects to reduce larval supply and population size of oysters and potentially other marine organisms. PMID- 29445024 TI - Quantitative analysis of the complete larval settlement process confirms Crisp's model of surface selectivity by barnacles. AB - For barnacle cypris larvae at the point of settlement, selection of an appropriate surface is critical. Since post-settlement relocation is usually impossible, barnacles have evolved finely tuned surface-sensing capabilities to identify suitable substrata, and a temporary adhesion system for extensive surface exploration. The pattern of exploratory behaviour appears complex and may last for several hours, imposing significant barriers to quantitative measurement. Here, we employ a novel tracking system that enables simultaneous analysis of the larval body movement of multiple individuals over their entire planktonic phase. For the first time, to our knowledge, we describe quantitatively the complete settlement process of cyprids as they explore and select surfaces for attachment. We confirm the 'classic' behaviours of wide searching, close searching and inspection that comprise a model originally proposed by Prof. Dennis Crisp FRS. Moreover, a short-term assay of cyprid body movement has identified inspection behaviour as the best indicator of propensity to settle, with more inspection-related movements occurring in conditions that also promote higher settlement. More than half a century after the model was first proposed by Crisp, there exists a precise method for quantifying cyprid settlement behaviour in wide-ranging investigations of barnacle ecology and applied studies of fouling management.

PMID- 29445025 TI - Strong conservation of inbred mouse strain microRNA loci but broad variation in brain microRNAs due to RNA editing and isomiR expression. AB - Diversity in the structure and expression of microRNAs, important regulators of gene expression, arises from SNPs, duplications followed by divergence, production of isomiRs, and RNA editing. Inbred mouse strains and crosses using them are important reference populations for genetic mapping, and as models of human disease. We determined the nature and extent of interstrain miRNA variation by (i) identifying miRNA SNPs in whole-genome sequence data from 36 strains, and (ii) examining miRNA editing and expression in hippocampus (Hpc) and frontal cortex (FCx) of six strains, to facilitate the study of miRNAs in neurobehavioral phenotypes. miRNA loci were strongly conserved among the 36 strains, but even the highly conserved seed region contained 16 SNPs. In contrast, we identified RNA editing in 58.9% of miRNAs, including 11 consistent editing events in the seed region. We confirmed the functional significance of three conserved edits in the miR-379/410 cluster, demonstrating that edited miRNAs gained novel target mRNAs not recognized by the unedited miRNAs. We found significant interstrain differences in miRNA and isomiR expression: Of 779 miRNAs expressed in Hpc and 719 in FCx, 262 were differentially expressed (190 in Hpc, 126 in FCx, 54 in both). We also identified 32 novel miRNA candidates using miRNA prediction tools. Our studies provide the first comprehensive analysis of SNP, isomiR, and RNA editing variation in miRNA loci across inbred mouse strains, and a detailed catalog of expressed miRNAs in Hpc and FCx in six commonly used strains. These findings will facilitate the molecular analysis of neurological and behavioral phenotypes in this model organism. PMID- 29445027 TI - A Curative-Intent Trimodality Approach for Isolated Abdominal Nodal Metastases in Metastatic Colorectal Cancer: Update of a Single-Institutional Experience. AB - BACKGROUND: The purpose of this study was to define survival rates in patients with isolated advanced abdominal nodal metastases secondary to colorectal cancer (CRC), treated with curative-intent trimodality therapy. MATERIALS AND METHODS: Sixty-five patients received trimodality therapy, defined as chemotherapy delivered with external beam radiotherapy (EBRT) followed by lymphadenectomy and intraoperative radiotherapy (IORT). Infusional 5-fluorouracil was the most common radiosensitizer used (63%, 41 patients). The median dose of EBRT was 50 Gy, and the median dose of IORT was 12.5 Gy. We evaluated time to distant metastasis, toxicities, local failure within the EBRT field, recurrence within the IORT field, and survival. RESULTS: Fifty-two percent of patients were male; patients' median age was 50.5 years. All patients had an Eastern Cooperative Oncology Group score <=1. Twenty-nine patients had right-sided colon cancer, 22 had left-sided colon cancer, and 14 had rectal primaries. The median time from initial CRC diagnosis to development of abdominal nodal metastatic disease was 20.6 months (95% confidence interval [CI], 21.2-40.8 months). Seventy-eight percent (51 patients) had para-aortic nodal metastases, 15% (10 patients) had mesenteric nodal metastases, and 6% (4 patients) had both. With a median follow-up of 77.6 months, the median overall survival and 5-year estimated survival rate were 55.4 months (95% CI, 47.2-80.9 months) and 45%, respectively. The median progression free survival was 19.3 months (95% CI, 16.5-32.8 months). Twenty-six (40%) patients never developed distant disease. The outcome was not affected by disease sidedness or rectal primary. Treatment was well tolerated without grade 3 or 4 toxicities. CONCLUSION: Trimodality therapy produces sustainable long-term survival in selected patients with metastatic CRC presenting with isolated retroperitoneal or mesenteric nodal relapse. IMPLICATIONS FOR PRACTICE: This article reports a unique trimodality approach incorporating external beam radiotherapy with radiosensitizing chemotherapy, surgical resection, and intraoperative radiotherapy provides durable survival benefit with significant curative potential for patients with metastatic colorectal cancer who present with isolated abdominal nodal (mesenteric and/or retroperitoneal) recurrence. PMID- 29445028 TI - Evaluation of Treatment Patterns and Survival Outcomes in Elderly Pancreatic Cancer Patients: A Surveillance, Epidemiology, and End Results-Medicare Analysis. AB - BACKGROUND: Management of pancreatic cancer (PC) in elderly patients is unknown; clinical trials exclude patients with comorbidities and those of extreme age. This study evaluated treatment patterns and survival outcomes in elderly PC patients using linked Surveillance, Epidemiology, and End Results (SEER) and Medicare data. MATERIALS AND METHODS: Histology codes 8140, 8500, 8010, 8560, 8490, 8000, 8260, 8255, 8261, 8263, 8020, 8050, 8141, 8144, 8210, 8211, or 8262 in Medicare Parts A and B were identified. Data regarding demographic, characteristics, treatments, and vital status between 1998 and 2009 were collected from the SEER. Determinants of treatment receipt and overall survival were examined using logistic regression and Cox proportional hazards models, respectively. RESULTS: A total of 5,975 patients met inclusion. The majority of patients were non-Hispanic whites (85%) and female (55%). Most cases presented with locoregional stage disease (74%); 41% received only chemotherapy, 30% chemotherapy and surgery, 10% surgery alone, 3% radiation, and 16% no cancer directed therapy. Patients with more advanced cancer, older age, and those residing in areas of poverty were more likely to receive no treatment. Among patients 66-74 years of age with locoregional disease, surgery alone (hazard ratio [HR] = 0.54; 95% confidence interval [CI]: 0.39-0.74) and surgery in combination with chemotherapy (HR = 0.69; 95% CI: 0.53-0.91) showed survival benefit as compared with the no treatment group. Among patients >=75 years of age with locoregional disease, surgery alone (HR = 2.04; 95% CI: 0.87-4.8) or in combination with chemotherapy (HR = 1.59; 95% CI: 0.87-2.91) was not associated with better survival. CONCLUSION: Treatment modality and survival differs by age and stage. Low socioeconomic status appears to be a major barrier to the receipt of PC therapy among Medicare patients. IMPLICATIONS FOR PRACTICE: Elderly patients with cancer are under-represented on clinical trials and usually have comorbid illnesses. The management of elderly patients with pancreatic cancer is unknown, with many retrospective experiences but low sample sizes. Using Surveillance, Epidemiology, and End Results-Medicare linked data to analyze treatment patterns and survival of elderly patients with pancreatic cancer on a larger population scale, this study highlights treatment patterns and their effect on survival and proposes possible obstacles to access of care in elderly patients with pancreatic cancer other than Medicare coverage. PMID- 29445029 TI - Pantoprazole, an Inhibitor of the Organic Cation Transporter 2, Does Not Ameliorate Cisplatin-Related Ototoxicity or Nephrotoxicity in Children and Adolescents with Newly Diagnosed Osteosarcoma Treated with Methotrexate, Doxorubicin, and Cisplatin. AB - LESSONS LEARNED: Using a randomized crossover design and continuous variables such as change in hearing threshold and biomarkers of acute renal injury as short term endpoints, it was determined that pantoprazole, an organic cation transporter 2 inhibitor, did not ameliorate cisplatin-associated nephrotoxicity or ototoxicity.Cystatin C is a robust method to estimate glomerular filtration rate in patients with cancer. Using a patient-reported outcome survey, all patients identified tinnitus and subjective hearing loss occurring "at least rarely" after cycle 1, prior to objective high-frequency hearing loss measured by audiograms.New therapies that improve outcome with less acute and long-term toxicity are needed. BACKGROUND: Organic cation transporter 2 (OCT2), which is a cisplatin uptake transporter expressed on renal tubules and cochlear hair cells but not on osteosarcoma cells, mediates cisplatin uptake. Pantoprazole inhibits OCT2 and could ameliorate cisplatin ototoxicity and nephrotoxicity. Using a randomized crossover design, we evaluated audiograms, urinary acute kidney injury (AKI) biomarkers, and glomerular filtration rate (GFR) estimated from cystatin C (GFRcysC) in patients receiving cisplatin with and without pantoprazole. MATERIALS AND METHODS: Cisplatin (60 mg/m2 * 2 days per cycle) was administered concurrently with pantoprazole (intravenous [IV], 1.6 mg/kg over 4 hours) on cycles 1 and 2 or cycles 3 and 4 in 12 patients with osteosarcoma (OS) with a median (range) age of 12.8 (5.6-19) years. Audiograms, urinary AKI biomarkers, and serum cystatin C were monitored during each cycle. RESULTS: Pantoprazole had no impact on decrements in hearing threshold at 4-8 kHz, post-treatment elevation of urinary AKI biomarkers, or GFRcysC (Fig. 1, Table 1). Histological response (percent necrosis) after two cycles was similar with or without pantoprazole. All eight patients with localized OS at diagnosis are alive and in remission; three of four patients with metastases at diagnosis have died. CONCLUSION: Pantoprazole did not ameliorate cisplatin ototoxicity or nephrotoxicity. The decrease in GFRcysC and increase in N-acetyl-beta-glucosaminidase (NAG) and creatinine demonstrate that these biomarkers can quantify cisplatin glomerular and proximal tubular toxicity. OCT2 inhibition by pantoprazole did not appear to alter antitumor response or survival. PMID- 29445030 TI - Cabozantinib in Patients with Advanced Merkel Cell Carcinoma. AB - BACKGROUND: This study sought to determine the efficacy and safety profile of cabozantinib in patients with advanced Merkel cell carcinoma (MCC). EXPERIMENTAL DESIGN: This prospective, phase II, single-institution trial enrolled patients with platinum-failure, recurrent/metastatic MCC to receive cabozantinib 60 mg orally daily until disease progression, withdrawal from study, or severe toxicity. The primary endpoint was disease control rate. Secondary endpoints included overall survival (OS), progression-free survival (PFS), and toxicity. Immunohistochemistry for VEGFR-2, MET, and HGF expression and next-generation sequencing of tumor tissue were performed and correlated with outcome. RESULTS: Eight patients were accrued from January 24, 2014, to June 8, 2016. The study was closed prematurely because of toxicity and lack of responses. The most frequent adverse events were grades 1 and 2 and included anorexia, fatigue, nausea, hypothyroidism, and dysgeusia. Two patients developed nonhealing, painful ulcers and tumor-skin fistula. One patient had stable disease for 8 months. One patient withdrew from the study after 2 weeks of therapy because of adverse events. Three patients required dose reduction because of toxicity. Median PFS and OS were 2.1 and 11.2 months, respectively. No expression of MET, HGF, or VEGFR-2 was identified in tumor cells by immunohistochemistry of patients' tissue samples. CONCLUSION: Cabozantinib was poorly tolerated and did not demonstrate activity in patients with recurrent/metastatic, platinum-failure MCC. It is unclear whether preselection of patients with the specific upregulation or genetic alteration in the targets for cabozantinib would have changed the results of this study. (Clinical trial identification number: NCT02036476) IMPLICATIONS FOR PRACTICE: This phase II study demonstrated poor tolerability and lack of activity of cabozantinib in an unselected group of patients with advanced Merkel cell carcinoma. Although it is unclear whether preselection of patients with the specific upregulation and genetic alterations in targets for cabozantinib would have changed the results of this study, this would have likely led to an extremely rare patient population that would take many years to accrue. PMID- 29445031 TI - The Perils of Single-Site Genetic Testing for Hereditary Cancer Syndromes in the Era of Next-Generation Sequencing. AB - : A challenge in counseling patients with a family history suggesting a hereditary cancer syndrome is deciding which genetic tests or panels to order. In this article, we discuss the identification of multiple familial mutations through genetic counseling and panel testing. For patients meeting National Comprehensive Cancer Network criteria for clinical genetic testing, providers should consider expanded panels to provide a more complete assessment of one's genetic risk. The continued use of expanded panel testing in the clinical setting will help inform optimal management of cancer patients, as well as the management of their unaffected family members. The mutation discovered in this case was in the ATM gene. The clinical significance of the mutation, potential therapeutic targets, and proper clinical management are discussed. KEY POINTS: With single site genetic testing, there is the potential to miss hereditary genetic syndromes that can be managed clinically.Between 4% and 6% of hereditary breast and ovarian cancer syndromes are caused by genes other than BRCA1 and BRCA2.ATM is a DNA mismatch repair gene associated with double-stranded DNA break repair and cell cycle checkpoint arrest.The risk of developing female breast cancer by age 50 and by age 80 in ATM heterozygotes is 9% and 17%-52%, respectively.

PMID- 29445035 TI - Comparative dynamics of microglial and glioma cell motility at the infiltrative margin of brain tumours. AB - Microglia are a major cellular component of gliomas, and abundant in the centre of the tumour and at the infiltrative margins. While glioma is a notoriously infiltrative disease, the dynamics of microglia and glioma migratory patterns have not been well characterized. To investigate the migratory behaviour of microglia and glioma cells at the infiltrative edge, we performed two-colour time lapse fluorescence microscopy of brain slices generated from a platelet-derived growth factor-B (PDGFB)-driven rat model of glioma, in which glioma cells and microglia were each labelled with one of two different fluorescent markers. We used mathematical techniques to analyse glioma cells and microglia motility with both single cell tracking and particle image velocimetry (PIV). Our results show microglia motility is strongly correlated with the presence of glioma, while the correlation of the speeds of glioma cells and microglia was variable and weak. Additionally, we showed that microglia and glioma cells exhibit different types of diffusive migratory behaviour. Microglia movement fit a simple random walk, while glioma cell movement fits a super diffusion pattern. These results show that glioma cells stimulate microglia motility at the infiltrative margins, creating a correlation between the spatial distribution of glioma cells and the pattern of microglia motility. PMID- 29445034 TI - The SKP1-Cullin-F-box E3 ligase betaTrCP and CDK2 cooperate to control STIL abundance and centriole number. AB - Deregulation of centriole duplication has been implicated in cancer and primary microcephaly. Accordingly, it is important to understand how key centriole duplication factors are regulated. E3 ubiquitin ligases have been implicated in controlling the levels of several duplication factors, including PLK4, STIL and SAS-6, but the precise mechanisms ensuring centriole homeostasis remain to be fully understood. Here, we have combined proteomics approaches with the use of MLN4924, a generic inhibitor of SCF E3 ubiquitin ligases, to monitor changes in the cellular abundance of centriole duplication factors. We identified human STIL as a novel substrate of SCF-betaTrCP. The binding of betaTrCP depends on a DSG motif within STIL, and serine 395 within this motif is phosphorylated in vivo SCF betaTrCP-mediated degradation of STIL occurs throughout interphase and mutations in the DSG motif causes massive centrosome amplification, attesting to the physiological importance of the pathway. We also uncover a connection between this new pathway and CDK2, whose role in centriole biogenesis remains poorly understood. We show that CDK2 activity protects STIL against SCF-betaTrCP mediated degradation, indicating that CDK2 and SCF-betaTrCP cooperate via STIL to control centriole biogenesis.

AB - Exceptional performance is often considered to be elegant and free of 'errors' or missteps. During the most extreme escape behaviours, neural control can approach or exceed its operating limits in response time and bandwidth. Here we show that small, rapid running cockroaches with robust exoskeletons select head-on collisions with obstacles to maintain the fastest escape speeds possible to transition up a vertical wall. Instead of avoidance, animals use their passive body shape and compliance to negotiate challenging environments. Cockroaches running at over 1 m or 50 body lengths per second transition from the floor to a vertical wall within 75 ms by using their head like an automobile bumper, mechanically mediating the manoeuvre. Inspired by the animal's behaviour, we demonstrate a passive, high-speed, mechanically mediated vertical transitions with a small, palm-sized legged robot. By creating a collision model for animal and human materials, we suggest a size dependence favouring mechanical mediation below 1 kg that we term the 'Haldane limit'. Relying on the mechanical control offered by soft exoskeletons represents a paradigm shift for understanding the control of small animals and the next generation of running, climbing and flying robots where the use of the body can off-load the demand for rapid sensing and actuation. PMID- 29445033 TI - Rett syndrome: a neurological disorder with metabolic components. AB - Rett syndrome (RTT) is a neurological disorder caused by mutations in the X linked gene methyl-CpG-binding protein 2 (MECP2), a ubiquitously expressed transcriptional regulator. Despite remarkable scientific progress since its discovery, the mechanism by which MECP2 mutations cause RTT symptoms is largely unknown. Consequently, treatment options for patients are currently limited and centred on symptom relief. Thought to be an entirely neurological disorder, RTT research has focused on the role of MECP2 in the central nervous system. However, the variety of phenotypes identified in Mecp2 mutant mouse models and RTT patients implicate important roles for MeCP2 in peripheral systems. Here, we review the history of RTT, highlighting breakthroughs in the field that have led us to present day. We explore the current evidence supporting metabolic dysfunction as a component of RTT, presenting recent studies that have revealed perturbed lipid metabolism in the brain and peripheral tissues of mouse models and patients. Such findings may have an impact on the quality of life of RTT patients as both dietary and drug intervention can alter lipid metabolism. Ultimately, we conclude that a thorough knowledge of MeCP2's varied functional targets in the brain and body will be required to treat this complex syndrome. PMID- 29445037 TI - On the diverse roles of fluid dynamic drag in animal swimming and flying. AB - Questions of energy dissipation or friction appear immediately when addressing the problem of a body moving in a fluid. For the most simple problems, involving a constant steady propulsive force on the body, a straightforward relation can be established balancing this driving force with a skin friction or form drag, depending on the Reynolds number and body geometry. This elementary relation closes the full dynamical problem and sets, for instance, average cruising velocity or energy cost. In the case of finite-sized and time-deformable bodies though, such as flapping flyers or undulatory swimmers, the comprehension of driving/dissipation interactions is not straightforward. The intrinsic unsteadiness of the flapping and deforming animal bodies complicates the usual application of classical fluid dynamic forces balance. One of the complications is because the shape of the body is indeed changing in time, accelerating and decelerating perpetually, but also because the role of drag (more specifically the role of the local drag) has two different facets, contributing at the same time to global dissipation and to driving forces. This causes situations where a strong drag is not necessarily equivalent to inefficient systems. A lot of living systems are precisely using strong sources of drag to optimize their performance. In addition to revisiting classical results under the light of recent research on these questions, we discuss in this review the crucial role of drag from another point of view that concerns the fluid-structure interaction problem of animal locomotion. We consider, in particular, the dynamic subtleties brought by the quadratic drag that resists transverse motions of a flexible body or appendage performing complex kinematics, such as the phase dynamics of a flexible flapping wing, the propagative nature of the bending wave in undulatory swimmers, or the surprising relevance of drag-based resistive thrust in inertial swimmers. PMID- 29445038 TI - Quantitative modelling of nutrient-limited growth of bacterial colonies in microfluidic cultivation. AB - Nutrient gradients and limitations play a pivotal role in the life of all microbes, both in their natural habitat as well as in artificial, microfluidic systems. Spatial concentration gradients of nutrients in densely packed cell configurations may locally affect the bacterial growth leading to heterogeneous micropopulations. A detailed understanding and quantitative modelling of cellular behaviour under nutrient limitations is thus highly desirable. We use microfluidic cultivations to investigate growth and microbial behaviour of the model organism Corynebacterium glutamicum under well-controlled conditions. With a reaction-diffusion-type model, parameters are extracted from steady-state experiments with a one-dimensional nutrient gradient. Subsequently, we employ particle-based simulations with these parameters to predict the dynamical growth of a colony in two dimensions. Comparing the results of those simulations with microfluidic experiments yields excellent agreement. Our modelling approach lays the foundation for a better understanding of dynamic microbial growth processes, both in nature and in applied biotechnology. PMID- 29445040 TI - Tailoring drug release rates in hydrogel-based therapeutic delivery applications using graphene oxide. AB - Graphene oxide (GO) is increasingly used for controlling mass diffusion in hydrogel-based drug delivery applications. On the macro-scale, the density of GO in the hydrogel is a critical parameter for modulating drug release. Here, we investigate the diffusion of a peptide drug through a network of GO membranes and GO-embedded hydrogels, modelled as porous matrices resembling both laminated and 'house of cards' structures. Our experiments use a therapeutic peptide and show a tunable nonlinear dependence of the peptide concentration upon time. We establish models using numerical simulations with a diffusion equation accounting for the photo-thermal degradation of fluorophores and an effective percolation model to simulate the experimental data. The modelling yields an interpretation of the control of drug diffusion through GO membranes, which is extended to the diffusion of the peptide in GO-embedded agarose hydrogels. Varying the density of micron-sized GO flakes allows for fine control of the drug diffusion. We further show that both GO density and size influence the drug release rate. The ability to tune the density of hydrogel-like GO membranes to control drug release rates has exciting implications to offer guidelines for tailoring drug release rates in hydrogel-based therapeutic delivery applications. PMID- 29445039 TI - Both lipopolysaccharide and lipoteichoic acids potently induce anomalous fibrin amyloid formation: assessment with novel AmytrackerTM stains. AB - In recent work, we discovered that the presence of highly substoichiometric amounts (10-8 molar ratio) of lipopolysaccharide (LPS) from Gram-negative bacteria caused fibrinogen clotting to lead to the formation of an amyloid form of fibrin. We here show that the broadly equivalent lipoteichoic acids (LTAs) from two species of Gram-positive bacteria have similarly (if not more) potent effects. Using thioflavin T fluorescence to detect amyloid as before, the addition of low concentrations of free ferric ion is found to have similar effects. Luminescent conjugated oligothiophene dyes (LCOs), marketed under the trade name AmytrackerTM, also stain classical amyloid structures. We here show that they too give very large fluorescence enhancements when clotting is initiated in the presence of the four amyloidogens (LPS, ferric ions and two LTA types). The staining patterns differ significantly as a function of both the amyloidogens and the dyes used to assess them, indicating clearly that the nature of the clots formed is different. This is also the case when clotting is measured viscometrically using thromboelastography. Overall, the data provide further evidence for an important role of bacterial cell wall products in the various coagulopathies that are observable in chronic, inflammatory diseases. The assays may have potential in both diagnostics and therapeutics. PMID- 29445042 TI - Working dogs transfer different tasks in reciprocal cooperation. AB - Direct reciprocity can establish stable cooperation among unrelated individuals. It is a common assumption of direct reciprocity models that agents exchange like with like, but this is not necessarily true for natural interactions. It is yet unclear whether animals apply direct reciprocity rules when successive altruistic help involves different tasks. Here, we tested whether working dogs transfer help from one to another cooperative task in an iterated prisoner's dilemma paradigm. In our experiment, individual dogs received help to obtain food from a conspecific, which involved a specific task. Subsequently, the focal subject could return received favour by using a different task. Working dogs transferred the cooperative experience received through one task by applying an alternative task when they helped a previously cooperative partner. By contrast, they refrained from helping previously defecting partners. This suggests that dogs realize the cooperative act of a conspecific, which changes their propensity to provide help to that partner by different means. The ability of animals to transfer different tasks when helping a social partner by satisfying the criteria of direct reciprocity might explain the frequent occurrence of reciprocal cooperation in nature. PMID- 29445041 TI - Generational shift in spring staging site use by a long-distance migratory bird. AB - In response to environmental change, species have been observed altering their migratory behaviours. Few studies, however, have been able to determine whether these alterations resulted from inherited, plastic or flexible changes. Here, we present a unique observation of a rapid population-level shift in migratory routes-over 300 km from Spain to Portugal-by continental black-tailed godwits Limosa limosa limosa This shift did not result from adult godwits changing staging sites, as adult site use was highly consistent. Rather, the shift resulted from young godwits predominantly using Portugal over Spain. We found no differences in reproductive success or survival among individuals using either staging site, indicating that the shift resulted from developmental plasticity rather than natural selection. Our results therefore suggest that new migratory routes can develop within a generation and that young individuals may be the agents of such rapid changes. PMID- 29445043 TI - Vestigial singing behaviour persists after the evolutionary loss of song in crickets. AB - The evolutionary loss of sexual traits is widely predicted. Because sexual signals can arise from the coupling of specialized motor activity with morphological structures, disruption to a single component could lead to overall loss of function. Opportunities to observe this process and characterize any remaining signal components are rare, but could provide insight into the mechanisms, indirect costs and evolutionary consequences of signal loss. We investigated the recent evolutionary loss of a long-range acoustic sexual signal in the Hawaiian field cricket Teleogryllus oceanicus Flatwing males carry mutations that remove sound-producing wing structures, eliminating all acoustic signalling and affording protection against an acoustically-orientating parasitoid fly. We show that flatwing males produce wing movement patterns indistinguishable from those that generate sonorous calling song in normal-wing males. Evolutionary song loss caused by the disappearance of structural components of the sound-producing apparatus has left behind the energetically costly motor behaviour underlying normal singing. These results provide a rare example of a vestigial behaviour and raise the possibility that such traits could be co-opted for novel functions. PMID- 29445044 TI - The extra burden of motherhood: reduced dive duration associated with pregnancy status in a deep-diving mammal, the northern elephant seal. AB - The cost of pregnancy is hard to study in marine mammals, particularly in species that undergo pregnancy while diving continuously at sea such as elephant seals (genus Mirounga). We analysed the diving behaviour of confirmed pregnant and non pregnant northern elephant seals (M. angustirostris, n = 172) and showed that after an initial continuous increase in dive duration, dives of pregnant females become shorter after week 17. The reasons for this reduction in dive duration remain unknown, but we hypothesize that increased fetal demand for oxygen could be the cause. Our findings reveal an opportunity to explore the use of biologging data to investigate pregnancy status of free-ranging marine mammals and factors that could affect pregnancy success. PMID- 29445046 TI - Expression of concern: Lionfish predators use flared fin displays to initiate cooperative hunting. PMID- 29445045 TI - Genomes to space stations: the need for the integrative study of migration for avian conservation. AB - Ongoing changes to global weather patterns and human modifications of the environment have altered the breeding and non-breeding ranges of migratory species, the timing of their migrations, and even whether they continue to migrate at all. Animal movements are arguably one of the most difficult behaviours to study, particularly in smaller birds that migrate tens to thousands of kilometres seasonally, often moving hundreds of kilometres each day. The recent miniaturization of tracking and logging devices has led to a radical transformation in our understanding of avian migratory behaviour and migratory connectivity. While advances in technology have altered the way researchers study migratory behaviour in the field, advances in techniques related to the study of physiological and genetic mechanisms underlying migratory behaviour have rarely been integrated into field studies of tracking. To predict the capacity of migrants to adjust to a changing planet, it is essential that we combine avian migration data with physiological and genetic measurements taken at key time points prior to, during and after migration. PMID- 29445047 TI - Association of Smoking with General and Abdominal Obesity: Evidence from a Cohort Study in West of Iran. AB - BACKGROUND: This study aimed to examine the association between smoking and obesity among adults in Kermanshah Province, west of Iran. STUDY DESIGN: A cross sectional study. METHODS: A total of 8822 participants, aged 35-65 yr, form Ravansar Non-communicable Disease (RaNCD) cohort study (2014-2016) were enrolled. Smoking habits were categorized in terms of smoking status (current, former and never smokers) and smoking intensity (light, moderate and heavy). General obesity was defined as body mass index (BMI) >=30 kg/m2 and abdominal obesity were defined as a waist to hip ratio (WHR) >=90 for men and >=85 for women. Multiple logistic regressions were used to examine the association between general and abdominal obesity with smoking status and smoking intensity while controlling for age, sex, years of education and wealth index. RESULTS: Overall, 12% were current smokers, 8.4% former smokers and 79.6% never smokers. The prevalence of light, moderate and heavy smokers among current smokers was 30.8%, 18%, and 51.2%, respectively. The prevalence of general obesity was 27.6%, while the prevalence of abdominal obesity was 82.3%. The probabilities of general and abdominal obesity for current smokers were lower than never smokers by 34% and 36%, respectively. The probability of abdominal obesity for heavy smokers was 31% lower than light smokers. We did not observe significant associations between smoking intensity and general obesity. CONCLUSIONS: Current smokers compared to never smokers were less likely to be obese. The reverse association between smoking and obesity; however, should not be interpreted as a causal relationship. PMID- 29445048 TI - Impact of Body Mass Index on Arterial Stiffness in Young Prehypertensives: A Cross Sectional Study. AB - BACKGROUND: Obesity and hypertension pose a big threat to public health. Targeting the prehypertension stage to evaluate the vascular damage due to obesity can help us to plan early interventions. STUDY DESIGN: A cross-sectional study. METHODS: This study as a part of the medical heath checkup program was conducted by the Medical College in Puducherry, India on all medical students of age group 18-25 years. Blood pressure (BP) recordings and body mass index (BMI) were classified into following four groups: Group1: Normotensives with normal BMI (n=109); Group 2: Normotensives with higher BMI (n=89); Group 3: Prehypertensive subjects with normal BMI (n=50); and Group 4: Prehypertensive subjects with higher BMI (n=99). Arterial stiffness, body fat composition, and lipid profile were evaluated. Correlation of arterial stiffness indices with BMI, BP, body fat, visceral fat, lipid profile were done using Pearson's correlation and the contribution of BMI to arterial stiffness was assessed using univariate regression analysis. RESULTS: BMI, arterial stiffness, body fat, visceral fat, total cholesterol and total triglyceride showed a significant increase in prehypertensive group with higher BMI as compared to other groups. BMI showed significant correlation with arterial stiffness (P<0.0001) and found to be an independent contributing factor for arterial stiffness development in prehypertensives. CONCLUSIONS: Vascular damage was seen in the prehypertensive stage itself and was more pronounced in individuals with higher BMI. PMID- 29445049 TI - Prevalence and Predictors of Internet Addiction among College Students in Sousse, Tunisia. AB - BACKGROUND: Internet represents a revolution in the world of technology and communication all over the world including Tunisia. However, this technology has also introduced problematic use, especially among students. The current study aimed to determine the prevalence of Internet addiction among college students and its predictors in the region of Sousse, Tunisia. STUDY DESIGN: A cross sectional study. METHODS: The current study was conducted in the colleges of Sousse, Tunisia in 2012-2013. A self-administrated questionnaire was used to collect data from 556 students in 5 randomly selected colleges from the region. Collected data concerned socio-demographic characteristics, substances use and internet addiction using the Young Internet Addiction Test. RESULTS: The response rate was 96%. The mean age of participants was 21.8+/-2.2 yr. Females represented 51.8% of them. Poor control of internet use was found among 280 (54.0%; CI95%: 49.7, 58.3%) participants. Low education levels among parents, the young age, lifetime tobacco use and lifetime illicit drugs use were significantly associated with poor control of internet use among students (P<0.001). While, the most influential factor on internet use among them was under-graduation with an adjusted odds ratio of 2.4 (CI95%: 1.7, 3.6). CONCLUSIONS: Poor control of internet use is highly prevalent among the college students of Sousse especially those under graduate. A national intervention program is required to reduce this problem among youth. A national study among both in-school and out-of-school adolescents and young people would identify at-risk groups and determine the most efficient time to intervene and prevent internet addiction. PMID- 29445050 TI - Has the Financial Protection Been Materialized in Iranian Health System? Analyzing Household Income and Expenditure Survey 2003-2014. AB - BACKGROUND: The financial protection against catastrophic and impoverishing health expenditures is one of the main aspects of the universal health coverage. This study aimed to present a clear picture of the financial protection situation in Iran from 2003-2014. STUDY DESIGN: This is an analytical study on secondary data of Statistical Center of Iran (SCI). The study has some policy implications for policy makers; therefore, it is an applied one. METHODS: Data related to the Iranian rural and urban household payments on health expenditures was obtained from annual surveys of the SCI. WHO researchers' approach was used to calculate the Fairness of Financial Contribution Indicator (FFCI), the headcount and overshoot ratios of catastrophic and impoverishing health expenditures. A logistic regression was conducted to identify the determinants of probability of occurrence of catastrophic health expenditure among Iranian households in 2014. RESULTS: The mean of FFCI for rural and urban households was 0.854 (0.41) and 0.867 (0.32), respectively. The average headcount ratios of catastrophic and impoverishing health expenditures were 1.32% (0.24) and 0.33% (P=0.006) for rural households and 1.4% (0.6) and 0.28% (P=0.001) for urban households. Concerning rural households, the overshoot of catastrophic and impoverishing health expenditures was 14.94% (P=0.001) and 7.22% (0.53); it was 15.59% (1.54) and 7.76% (0.52) for urban households. CONCLUSIONS: No significant and considerable change was found in the headcount ratios of catastrophic and impoverishing health expenditure and in their overshoot or gap amounts. This suggested a lack of well designed and effective schemes for materializing the financial protection in Iran. PMID- 29445051 TI - Socioeconomic Inequalities in Poor Health-Related Quality of Life in Kermanshah, Western Iran: A Decomposition Analysis. AB - BACKGROUND: Socioeconomic status (SES) is an important determinant of health related quality of life (HRQoL). We aimed to quantify socioeconomic-related inequality in poor-HRQoL among adults in Kermanshah, western Iran. STUDY DESIGN: A cross-sectional study. METHODS: Overall, 1730 adults (18-65 yr) were selected using convenience sampling from Kermanshah, Iran. A self-administrated questionnaire was used to collect data on socio-demographic characteristics, SES, lifestyle factors and HRQoL of participants over the period between May and Aug 2017. The concentration curve and concentration index (C) were used to illustrate and measure wealth-related inequality in poor-HRQoL. Additionally, we decomposed the C index to identify factors explaining wealth-related inequality in poor HRQoL. RESULTS: The overall prevalence of poor-HRQoL was 35.3% (95% confidence interval[CI]: 33.1%, 37.6%). The poor-HRQoL was mainly concentrated among the poor adults (C=-0.256, 95% CI: -0.325, -0.187). Poor-HRQoL was concentrated among men (C=-0.256, 95% CI: -0.345, -0.177) and women (C=-0.261, 95% CI: -0.310, 0.204). Wealth, physical inactivity, the presence of chronic health condition(s), lack of health insurance coverage were the main factors contributing to the concentration of poor-HRQoL among socioeconomically disadvantaged adults. CONCLUSIONS: Socioeconomic-related inequalities in poor-HRQoL among adult should warrant more attention. Policies should be designed to not only improve HRQoL among adults but also reduce the pro-rich distribution of HRQoL among adults in Kermanshah. PMID- 29445052 TI - Increase in breath hydrogen concentration was correlated with the main pancreatic duct stenosis. AB - BACKGROUND: Hydrogen is produced from unabsorbed carbohydrates in the intestine through degradation and metabolism by hydrogenase of intestinal bacteria. The hydrogen is then partially diffused into blood flow and released and detected in exhaled breath. Pancreatic juice production is decreased in patients with reduced pancreatic exocrine function, including those with pancreatic cancer, thus decreasing digestion and absorption of nutrients including carbohydrates, which may increase undigested carbohydrates in the intestine and increase breath hydrogen concentration (BHC). The aim of this study was to investigate the association between BHC and pancreatic diseases. METHODS: A retrospective study was designed and 68 patients underwent morning fasting breath hydrogen test. Since there is no clear standard, normal BHC, the median of the measured values from the subjects (9 ppm) was adopted as the standard. The subjects were classified into those with a value exceeding the median (BHC high group: 32 patients) and a value equal to or below the median (BHC low group: 36 patients). Patients characteristics, blood test results and imaging findings characteristic of pancreatic diseases were compared between the groups. RESULTS: The age was significantly higher (P = 0.010) and the incidences of pancreatic ductal adenocarcinoma and autoimmune pancreatitis were significantly higher (P = 0.018 and P = 0.004, respectively) in the BHC high group. With respect to the blood test items, the Alb level was significantly lower in the BHC high group (P = 0.005). With respect to the characteristic imaging findings of pancreatic diseases, the proportions of patients with pancreatic enlargement, the main pancreatic duct (MPD) stenosis, and the MPD dilatation were significantly higher in the BHC high group (P = 0.022, P < 0.001, and P = 0.002, respectively). On univariate analysis, only the MPD stenosis was extracted as an independent factor (P = 0.014). CONCLUSION: It was suggested that the fasting BHC is associated with pancreatic diseases causing stenosis of the MPD, including pancreatic cancer (UMIN000020777). PMID- 29445053 TI - SPIRAL2 Stabilises Endoplasmic Microtubule Minus Ends in the Moss Physcomitrella patens. AB - Stabilisation of minus ends of microtubules (MTs) is critical for organising MT networks in land plant cells, in which all MTs are nucleated independent of centrosomes. Recently, Arabidopsis SPIRAL2 (SPR2) protein was shown to localise to plus and minus ends of cortical MTs, and increase stability of both ends. Here, we report molecular and functional characterisation of SPR2 of the basal land plant, the moss Physcomitrella patens. In protonemal cells of P. patens, where non-cortical, endoplasmic MT network is organised, we observed SPR2 at minus ends, but not plus ends, of endoplasmic MTs and likely also of phragmoplast MTs. Minus end decoration was reconstituted in vitro using purified SPR2, suggesting that moss SPR2 is a minus end-specific binding protein (-TIP). We generated a loss-of-function mutant of SPR2, in which frameshift-causing deletions/insertions were introduced into all four paralogous SPR2 genes by means of CRISPR/Cas9. Protonemal cells of the mutant showed instability of endoplasmic MT minus ends. These results indicate that moss SPR2 is a MT minus end stabilising factor.Key words: acentrosomal microtubule network, microtubule minus end, P. patens, CAMSAP/Nezha/Patronin. PMID- 29445055 TI - An Inappropriate Shock Case Early after Implantation of a Subcutaneous Cardiac Defibrillator by Subcutaneous Entrapped Air. AB - A 17-year-old woman was resuscitated from cardiac arrest due to ventricular fibrillation and was diagnosed with concealed long QT syndrome. She underwent subcutaneous implantable cardiac defibrillator (S-ICD) implantation at our hospital. The device electrogram immediately after implantation was normal. Four days after implantation, she received an inappropriate shock. The device interrogation revealed a continuous baseline shift and frequent oversensing for low amplitude signals, followed by a shock. A chest radiograph in the orthogonal view showed entrapped subcutaneous air surrounding the distal electrode. Entrapped subcutaneous air can cause inappropriate shocks in the early period after S-ICD implantation. PMID- 29445054 TI - Comparison of Drug Metabolism and Its Related Hepatotoxic Effects in HepaRG, Cryopreserved Human Hepatocytes, and HepG2 Cell Cultures. AB - Differentiated HepaRG cells maintain liver-specific functions such as drug metabolizing enzymes. In this study, the feasibility of HepaRG cells as a human hepatocyte model for in vitro toxicity assessment was examined using selected hepatotoxic compounds. First, basal drug-metabolizing enzyme activities (CYP1A2, CYP2B6, CYP2C9, CYP2C19, CYP2D6, CYP3A4, uridine 5'-diphospho glucuronosyltransferase [UGT], and sulfotransferases [SULT]) were measured in HepaRG, human hepatocytes, and HepG2 cells. Enzyme activities in differentiated HepaRG cells were comparable to those in human hepatocytes and much higher than those in HepG2 cells, except for SULT activity. Second, we examined the cytotoxicity of hepatotoxic compounds, acetaminophen (APAP), aflatoxin B1 (AFB1), cyclophosphamide (CPA), tamoxifen (TAM), and troglitazone (TGZ) in HepaRG cells and human hepatocytes. AFB1- and CPA-induced cytotoxicities against HepaRG cells were comparable to those against human hepatocytes. Furthermore, the cytotoxicities of these compounds were inhibited by 1-aminobenzotriazole (ABT), a broad CYP inhibitor, in both cells and were likely mediated by metabolic activation by CYP. Finally, toxicogenomics analysis of HepG2 and HepaRG cells after exposure to AFB1 and CPA revealed that numerous p53-related genes were upregulated- and the expression of these genes was greater in HepaRG than in HepG2 cells. These results suggest that gene expression profiles of HepaRG cells were affected more considerably by the toxic mechanisms of AFB1 and CPA than the profiles of HepG2 cells were. Therefore, our investigation shows that HepaRG cells could be useful human hepatic cellular models for toxicity studies. PMID- 29445056 TI - Decreased Serum Relaxin-2 Is Correlated with Impaired Islet beta-Cell Function in Patients with Unstable Angina and Abnormal Glucose Metabolism. AB - Circulating relaxin (RLX) is altered in patients with diabetes mellitus (DM) or cardiovascular diseases. This study was designed to evaluate the changes of RLX in patients with unstable angina (UA) complicated with various categories of abnormal glucose metabolism.Patients who confirmed UA by angiographic and clinical standard were grouped according to the glucose metabolism status with oral glucose tolerance test (OGTT) and medical history categorized as normal, prediabetes, newly diagnosed type 2 DM (T2DM), and previously diagnosed T2DM. Serum RLX-2 was measured and islet beta-cell function was evaluated. The severity of the coronary arterial lesions was evaluated with Syntax Scores.Serum RLX-2 was significantly higher in UA patients with prediabetes (median [quartiles]: 9.87 [7.48, 32.58] pg/mL) and newly diagnosed T2DM (18.36 [9.52, 48.08] pg/mL), compared with those with normal glucose tolerance (6.24 [4.02, 7.27] pg/mL, both P < 0.05). Interestingly, UA patients with previously diagnosed T2DM exhibited lower RLX-2 levels (4.17 [3.23, 5.72] pg/mL) compared with those with normal glucose tolerance (P < 0.05). Subsequent analyses indicated that serum RLX-2 was positively associated with parameters of islet beta-cell function, C-peptide, and fasting insulin levels; however, it was negatively associated with the levels of fasting glucose, 2-hour postprandial blood glucose, HbA1c, and insulin sensitivity, suggesting a potential protective role of RLX-2 during abnormal glucose metabolism in UA patients. Serum RLX-2 was not correlated with the Syntax Scores in these patients.Serum RLX-2 is a potential marker for UA patients with early glucose metabolism abnormality, and increased RLX-2 level was correlated with preserved islet beta-cell function. PMID- 29445057 TI - Utility of Fluid Assessment Based on the Intrathoracic Impedance Monitoring in a Peripartum Woman with Heart Disease. AB - Recently, implantable cardioverter-defibrillators (ICD) have become capable of monitoring intrathoracic impedance to detect an increased fluid volume and heart failure. Pregnancy is a well-known cause of an increased body fluid volume; however, it is not clear whether the measurement of intrathoracic impedance by ICD is clinically useful for precisely detecting heart failure in pregnant women. We herein report the case of a 39-year-old woman with an ICD that had been implanted after an event of ventricular fibrillation due to severe aortic regurgitation with a bicuspid aortic valve. Elevated right ventricular pressure and brain natriuretic peptide levels were detected at 37 weeks of gestation and postpartum. At the same time, the ICD's stored fluid index gradually increased and exceeded the threshold on the 10th day after delivery. She was treated with diuretics and recovered from postpartum heart failure. The physiological volume changed in the perinatal period, but we were still able to detect heart failure by ICD. Intrathoracic impedance monitoring is effective in the perinatal field. PMID- 29445058 TI - Nonfasting Glucose and Incident Stroke and Its Types - The Circulatory Risk in Communities Study (CIRCS). AB - BACKGROUND: The effect of postprandial glucose on the risk of cardiovascular disease has been emphasized, but it is controversial whether nonfasting glucose is related to incident stroke and its types.Methods and Results:We investigated the associations of nonfasting glucose with incident stroke and its types among 7,198 participants aged 40-74 years from the Circulatory Risk in Communities Study, enrolled in 1995-2000. We estimated multivariable hazard ratios (HR) using Cox proportional hazard models. Over a median follow-up of 14.1 years, 291 cases of total stroke (ischemic strokes: 191 including 109 lacunar infarctions) were identified. Nonfasting glucose concentration was associated with greater risk of incident total stroke, ischemic stroke and lacunar infarction when modeled categorically (for prediabetic type: 7.8-11.0 mmol/L vs. normal type: <7.8 mmol/L among all subjects, HR for lacunar infarction was 2.02, 95% confidence interval (CI): 1.19, 3.43) or continuously (per one standard deviation increment among all subjects, HR for lacunar infarction was 1.29, 95% CI: 1.15, 1.45). Diabetic type showed similar results. Population attributable fractions of nonfasting hyperglycemia were 13.2% for ischemic stroke and 17.4% for lacunar infarction. CONCLUSIONS: Nonfasting glucose concentration, either as a diagnosis of prediabetic and diabetic types or as a continuous variable, proved to be an independent predictor significantly attributed to incident total stroke, especially ischemic stroke and lacunar infarction, in the general population. PMID- 29445059 TI - Liver Cirrhosis and/or Hepatocellular Carcinoma Occurring Late After the Fontan Procedure - A Nationwide Survey in Japan. AB - BACKGROUND: Fontan-associated liver disease (FALD) is an important late complication involving liver dysfunction, such as liver cirrhosis (LC) and hepatocellular carcinoma (HCC), in patients undergoing the Fontan procedure. However, the prevalence, clinical manifestation, and methods of diagnosis of FALD are still not well established.Methods and Results:This study comprised 2 nationwide surveys in Japan. First, the prevalence of LC and/or HCC in patients undergoing the Fontan procedure was determined. Second, clinical manifestations in patients with LC and/or HCC were analyzed, along with data from blood tests, echocardiography, and right heart catheterization. In the 1st survey, of the 2,700 patients who underwent the Fontan procedure, 31 were diagnosed with LC and/or HCC (1.15%), and 5 died due to liver diseases (mortality: 0.19%). In the 2nd survey, data were collected from 17 patients (12 with LC, 2 with HCC, and 3 with LC+HCC. Of these 17 patients, 5 died (mortality: 29.4%). The mean age at diagnosis of LC and HCC was 23 and 31 years, respectively. Computed tomography followed by ultrasound was most frequently used for diagnosis. Blood tests revealed low platelet counts, increased hemoglobin, aspartate aminotransferase, gamma-guanosine triphosphate, and total bilirubin levels, and an elevated international normalized ratio of prothrombin time. CONCLUSIONS: LC and/or HCC in patients undergoing the Fontan procedure were not rare late complications and were associated with high mortality rates.

AB - Prevention of sudden cardiac death (SCD) has become an important issue in today's cardiovascular field, together with various developments in secondary prevention of basic cardiac diseases. The importance of the implantable cardioverter defibrillator (ICD) is now widely accepted because it has exhibited significant improvement in patients' prognoses in ischemic and non-ischemic cardiovascular diseases. However, there is an unignorable gap between the ICD indication in the guidelines and real-world high-risk patients for SCD, especially in the acute recovery phase of cardiac injury. Although various studies have demonstrated a clinical benefit of defibrillation devices, the studies of immediate ICD use in the acute recovery phase have failed to exhibit a benefit in patients from the point of the view of a decrease in total deaths. To bridge this gap, the wearable cardioverter defibrillator (WCD) provides a safer observation period in the acute phase and eliminates inappropriate overuse of ICD in the subacute phase. Here, we discuss the usefulness of the WCD and current understanding of its indications based on various clinical data. In conclusion, WCD is a feasible bridge to therapy and/or safe observation for patients at high risk of SCD, especially in the acute recovery phase of cardiac diseases. PMID- 29445061 TI - The Prophylactic Effect of Anti-influenza Agents for an Influenza Outbreak in a University Hospital. AB - Objective From November 24 to December 9, 2013, an outbreak of the influenza (flu) A (H3) virus occurred in a tertiary-care university hospital (1,014 beds). We herein report the prophylactic effect of anti-flu agents for controlling the flu outbreak. Methods We administered pre- or post-exposure prophylaxis with anti flu agents in flu outbreak. To test the effectiveness of prophylaxis in a flu outbreak, we used the posterior mean of the reproductive value during the pre- and post-intervention period. We also simulated the probability distribution of new flu cases. We performed an analysis to quantify the strength of the intervention effect. Results A total of 97 people were diagnosed with flu before the intervention, and 7 were diagnosed after the intervention. A molecular analysis of the flu virus revealed that this outbreak was due to the flu A (H3) virus. A total of 3,702 people received prophylaxis. There was a significant reduction in the reproductive value from 1.89 [95% confidence interval (CI), 1.59 to 2.24] to 0.65 (95% CI, 0.02 to 1.00) after the intervention (p<0.001). Conclusion Prophylaxis with anti-flu agents, along with prompt identification and isolation of infected individuals, was effective in reducing the impact of a flu outbreak in a hospital.

PMID- 29445064 TI - The validity of anesthetic protocols for the surgical procedure of castration in rats. AB - To achieve surgical anesthesia in animal experimentation, it is necessary to select the appropriate anesthetic protocol by considering its pharmacological properties and the surgical procedure to be performed. However, few studies have investigated the validity of anesthetic protocols under surgical conditions in small rodents. The present study aimed to clarify the pharmacological properties of 4 anesthetic protocols during the surgical procedure of castration in rats. Eight-week-old male Wistar rats were anesthetized with anesthetics, including the combination of ketamine and xylazine (K/X), the combination of medetomidine, midazolam, and butorphanol (M/M/B), isoflurane, and sevoflurane. Castration was performed under each anesthesia, and anesthetic depth and times were assessed, as were vital signs. The injectable anesthetics were investigated at standard and high doses. The concentration of inhalant anesthetics was adjusted to 1.5 minimum alveolar concentration (MAC). K/X at both doses demonstrated sufficient anesthetic depth with rapid induction and recovery. However, bradycardia and hypothermia were prominent in high-dose K/X, indicating that the standard-dose is more appropriate for surgical anesthesia in castration procedures. M/M/B demonstrated high anesthetic sensitivity variation in individual animals. In contrast to injectable anesthetics, inhalant anesthetics provided stable anesthetic depth with less cardiorespiratory influence. Sevoflurane did not lead to a significant decrease in rectal temperature during the anesthetic period. Results of the present study revealed the optimal dose and pharmacological features of several anesthetic protocols for castration, and may contribute to the standardization of surgical anesthesia in rats. PMID- 29445065 TI - Questionnaire Survey From the Viewpoint of Concordance in Patient and Physician Satisfaction Concerning Hypertensive Treatment in Elderly Patients - Patients Voice Study. AB - BACKGROUND: Patient-physician concordance is an important concern in the treatment of elderly patients with hypertension (HT). Treatment that considers concordance is necessary for mutual understanding and therapeutic satisfaction between patients and physicians. However, there have been no studies addressing concordance that objectively analyzed both patient and physician satisfaction before and after treatment.Methods and Results:An exploratory open-label, multicenter, intervention study was conducted. Patients with HT undergoing treatment with angiotensin-receptor blocker (ARB) or a calcium-channel blocker (CCB) monotherapy were enrolled. Medication was switched to an ARB/CCB combination tablet and taken for 12 weeks. Physicians and patients participated in satisfaction surveys concerning treatment. Discrepancies in satisfaction levels between patients and physicians were found at baseline for the following survey items: treatment, involvement in treatment, understanding of HT, reliance, medication, and blood pressure. After treatment, the satisfaction levels of both patients and physicians increased; discrepancies in satisfaction between the groups also improved. CONCLUSIONS: The rates of satisfaction were relatively higher for patients compared with physicians at baseline. After HT treatment addressing concordance, both patient and physician satisfaction rates and the gap in satisfaction rates between patients and physicians improved. This indicates that addressing concordance has clinical significance in the treatment of elderly HT patients. (UMIN000017270). PMID- 29445066 TI - Epidemiology of Pediatric Out-of-Hospital Cardiac Arrest at School - An Investigation of a Nationwide Registry in Japan. AB - BACKGROUND: A better understanding of the epidemiology of pediatric out-of hospital cardiac arrest (OHCA) occurring in school settings is important to establish an evidence-based strategy for prevention and better prognosis.Methods and Results:The Stop and Prevent cardIac aRrest, Injury, and Trauma in Schools (SPIRITS) is a nationwide prospective observational study linking databases from 2 nationally representative registries, the Injury and the Accident Mutual Aid Benefit System of The Japan Sport Council and the All-Japan Utstein Registry of the Fire and Disaster Management Agency. Using these databases, we described the detailed characteristics and outcomes of pediatric OHCAs that occurred in school settings in Japan between 2009 and 2014. During the 6-year study period, 295 OHCA cases were confirmed. Overall incidence rate was 0.4 per 100,000 students per year. The majority of OHCA cases had a cardiac origin (71%), occurred during exercise (65%), were witnessed by bystanders (70%), and received bystander initiated cardiopulmonary resuscitation (73%). In approximately one-third of cases the student was defibrillated by public-access automated external defibrillator (38%). The proportion of patients with 1-month survival and a favorable neurological outcome was 34% among all OHCAs and 43% among OHCAs of cardiac origin. CONCLUSIONS: In Japan, approximately 50 pediatric cases of OHCA consistently occur yearly in school settings. The majority of students received basic life support from bystanders, and patients with OHCA of cardiac origin had a relatively good prognosis. PMID- 29445067 TI - Circulating Fatty Acid-Binding Protein 4 Concentration Predicts the Progression of Carotid Atherosclerosis in a General Population Without Medication. AB - BACKGROUND: Fatty acid-binding protein 4 (FABP4), which is expressed in both adipocytes and macrophages, is secreted from the cells and acts as an adipokine. An elevated circulating FABP4 level is associated with insulin resistance and atherosclerosis.Methods and Results:We investigated the causative association between FABP4 level and progression of atherosclerosis in subjects of the Tanno Sobetsu Study, a population-based cohort. In 281 subjects without medication (male/female: 109/172) in the year 2010 or 2013, the carotid intima-media thickness (CIMT) assessed using carotid ultrasonography was significantly correlated with age, adiposity, blood pressure, renal dysfunction and levels of cholesterol, triglycerides, fasting glucose, HbA1c and FABP4 (r=0.331, P<0.001). Multiple regression analysis demonstrated that age, sex and FABP4 concentration were independent predictors of CIMT. A total of 78 (male/female: 29/49) of the 156 subjects in 2010 underwent carotid ultrasonography again in 2013. The change in CIMT each year during that 3-year period (mean+/-SD: 3.8+/-22.3 um/year) was positively correlated with basal levels of high-sensitivity C-reactive protein (hsCRP) (r=0.231, P=0.046) and FABP4 (r=0.267, P=0.018) in 2010. After adjustment for age, sex and hsCRP level, the basal FABP4 level was independently associated with the change in CIMT per year. CONCLUSIONS: FABP4 concentration is an independent predictor of the progression of carotid atherosclerosis. PMID- 29445068 TI - Lower Plasma Levels of IL-35 in Patients with Primary Biliary Cirrhosis. AB - Primary biliary cirrhosis (PBC) is an autoimmune liver disease. Its histological characteristics, such as progressive intrahepatic bile duct destruction, cholestasis, and liver cirrhosis, are caused by the body's autoimmune disorders. Interleukin (IL)-35 has two subunits (p35 and Ebi3) and is a member of the IL-12 family of heterodimeric cytokines. IL-35 has immunosuppressive functions and plays an important role in many autoimmune diseases. In this study, we compared plasma levels of IL-35 and relative mRNA expression levels of p35 and Ebi3 in peripheral blood mononuclear cells (PBMCs) from 70 PBC patients and 70 healthy individuals. The results showed that the relative expression levels of Ebi3 mRNA were lower in PBMCs from PBC patients than in PBMCs from healthy individuals, whereas the levels of p35 mRNA were similar in both groups. Plasma IL-35 concentrations were lower in patients with PBC than in healthy individuals. Plasma levels were higher in PBC patients at an advanced stage compared to patients at an early stage. Variable plasma levels with different stages were also found in transforming growth factor beta (TGF-beta), which is mainly produced by regulatory T cells (Tregs). IL-35 and TGF-beta levels were positively correlated with each other, and IL-35 was capable of promoting the inhibitory functions of Tregs in PBC patients at both the early and late stages of disease. Lower plasma IL-35 levels were accompanied by higher levels of typical clinical parameters, such as alkaline phosphatase, or of proinflammatory cytokines, such as interferon-gamma (IFN-gamma), in PBC patients (P < 0.05 for each). We propose that IL-35 may be involved in the pathogenesis of PBC and could be a potential biomarker for diagnosing this disease. PMID- 29445069 TI - Expression and distribution of the zinc finger protein, SNAI3, in mouse ovaries and pre-implantation embryos. AB - The Snail gene family includes Snai1, Snai2, and Snai3 that encode zinc finger containing transcriptional repressors in mammals. The expression and localization of SNAI1 and SNAI2 have been studied extensively during folliculogenesis, ovulation, luteinization, and embryogenesis in mice. However, the role of SNAI3 is unknown. In this study, we investigated the expression of SNAI3 during these processes. Our immunohistochemistry data showed that SNAI3 first appeared in oocytes by postnatal day (PD) 9. Following this, SNAI3 was found to be expressed consistently in theca and interstitial cells, along with oocytes. In gonadotropin treated immature mice, the expression of SNAI3 did not change significantly during follicular development. The expression of SNAI3 was reduced during ovulation, after which it increased gradually during luteinization. Similar results were obtained from western blot analyses. Furthermore, real-time polymerase chain reaction (RT-PCR) analyses revealed varying mRNA levels of different Snail factors at a given time in gonadotropin-induced ovaries. During early embryo cleavage, SNAI3 was localized to the nucleus, except the nucleolus at the germinal vesicle and one-cell stages. From two- to eight-cell stages, SNAI3 was localized only to the nucleolus. Thereafter, SNAI3 was detected only in the cytoplasm, except during the blastocyst stage when it was localized to the nucleus of the trophectoderm and the inner cell mass. RT-PCR results showed that the expression of Snail superfamily genes was decreased during the blastocyst stage. From the eight-cell to morula stage, when compaction occurs that is a prerequisite for blastocyst formation, Snai3 mRNA was expressed at very low levels and was opposite to the highest expression level of the compaction-related gene, E-cadherin, at the eight-cell stage. Taken together, our results suggest that SNAI3 likely plays some roles during folliculogenesis, luteinization, and early embryonic development. PMID- 29445070 TI - Development to term of sheep embryos reconstructed after inner cell mass/trophoblast exchange. AB - Here we report in vitro and term development of sheep embryos after the inner cell mass (ICM) from one set of sheep blastocysts were injected into the trophoblast vesicles of another set. We also observed successful in vitro development of chimeric blastocysts made from sheep trophoblast vesicles injected with bovine ICM. First, we dissected ICMs from 35 sheep blastocysts using a stainless steel microblade and injected them into 29 re-expanded sheep trophoblastic vesicles. Of the 25 successfully micromanipulated trophoblastic vesicles, 15 (51.7%) re-expanded normally and showed proper ICM integration. The seven most well reconstructed embryos were transferred for development to term. Three ewes receiving manipulated blastocysts were pregnant at day 45 (42.8%), and all delivered normal offspring (singletons, two females and one male, average weight: 3.54 +/- 0.358 kg). Next, we monitored in vitro development of sheep trophoblasts injected with bovine ICMs. Of 17 injected trophoblastic vesicles, 10 (58.8%) re-expanded after 4 h in culture, and four (40%) exhibited integrated bovine ICM. Our results indicate that ICM/trophoblast exchange is feasible, allowing full term development with satisfactory lambing rate. Therefore, ICM exchange is a promising approach for endangered species conservation. PMID- 29445071 TI - A case report of thyroid metastasis from p16-positive oropharyngeal squamous cell carcinoma. AB - Thyroid metastasis from head and neck squamous cell carcinoma (SCC) is a very rare form of rarely observed metastatic thyroid tumor. We herein report a case of thyroid metastasis from oropharyngeal SCC (OSCC). The patient was a 68-year-old male diagnosed with p16-positive tonsillar OSCC on the right side with multiple lymph node metastases and a thyroid mass, which was determined as metastatic p16 positive OSCC by immunohistochemistry of specimens collected by fine-needle aspiration cytology (FNAC). He received one cycle of induction chemotherapy followed by concurrent chemoradiotherapy. No visible primary lesions were observed after treatment. The disappearance of the tonsillar lesion was considered to be a complete response by the magnetic resonance imaging (MRI) and positron emission tomography-computed tomography (PET-CT). The thyroid lesion was also decreased, but a solid lesion with unclear boundaries in the right thyroid lobe remained. Therefore, the patient underwent total thyroidectomy to remove any residual tumor. Postoperative pathological evaluation revealed no residual viable carcinoma cells in the resected specimen. As illustrated in this case, immunohistochemistry of the FNAC specimen for p16 was successful in determining the thyroid tumor as a metastatic lesion from the oropharynx. Although radical radiotherapy might be sufficient to control thyroid gland metastasis of OSCC, in this case, early-stage remedial surgery was thought to be necessary for a secure radical cure. PMID- 29445072 TI - Molar eruption and identification of the eastern grey kangaroo (Macropus giganteus) at different ages. AB - To treat dental disorders and estimate age, it is important that veterinarians understand teeth eruption sequence for the animal in question. Few dental images of the eastern grey kangaroo have been published. In the present study, radiographic imagings of 29 kangaroos, ranging in age from 12 months to 10 years 9 months, was used to surveil the replacement of premolars and the eruption of molars. These images revealed eruption patterns in five stages, while the second and third deciduous premolars were shed non-systematically. Furthermore, the third premolars and fourth molars erupted in the mandible earlier than in the maxilla, which may contribute to the frequency of mandibular dental disorders. PMID- 29445073 TI - Adiponectin deficiency-induced diabetes increases TNFalpha and FFA via downregulation of PPARalpha. AB - Expression of peroxisome proliferator-activated receptor (PPAR) alpha was investigated in adiponectin knockout mice to elucidate the relationship between PPARalpha and adiponectin deficiency-induced diabetes. Adiponectin knockout (Adp /-) mice were generated by gene targeting. Glucose tolerance test (GTT), insulin tolerance test (ITT), and organ sampling were performed in Adp-/- mice at the age of 10 weeks. PPARalpha, insulin, triglyceride, free fatty acid (FFA), and tumor necrosis factor alpha (TNFalpha) were analyzed from the sampled organs. Adp-/- mice showed impaired glucose tolerance and insulin resistance. Additionally, PPARalpha levels were decreased and plasma concentration of triglyceride, FFA and TNFalpha were increased. These data may indicate that insulin resistance in Adp-/ mice is likely caused by an increase in concentrations of TNFalpha and FFA via downregulation of PPARalpha. PMID- 29445074 TI - Intrapancreatic accessory spleen in a harbor porpoise (Phocoena phocoena). AB - The occurrence of accessory spleens in cetacean species is high yet confirmed reports of intrapancreatic accessory spleen, a congenital malformation, remain undescribed. The current study provides the gross, microscopical, histochemical and immunohistochemical features of an intrapancreatic accessory spleen in a harbor porpoise (Phocoena phocoena). Grossly, a 17 * 18 * 9 mm well-demarcated, dark brown to red mass expanded the left pancreatic lobe. Microscopically, this mass consisted of mature splenic tissue interspersed with exocrine pancreatic acini. Intrapancreatic accessory spleens should be considered in the list of differential diagnoses for intrapancreatic nodular lesions in cetaceans.

AB - A practical Pd-catalyzed carbonylation of (hetero)aryl bromides using a crystalline carbon monoxide (CO) surrogate, 2,4,6-trichlorophenyl formate (TCPF), was developed. This reaction proceeds without the slow addition technique that was previously required and with a low catalyst loading (1 mol%). The utility of this Pd-catalyzed external-CO-free carbonylation using TCPF was demonstrated in the synthesis of a histone deacetylase inhibitor. PMID- 29445077 TI - Successful External Cardioversion via Fluoroscopic Electrode Positioning in Patients with Enlarged Trans-Thoracic Diameter. AB - BACKGROUND Atrial fibrillation is the most common cardiac arrhythmia. It increases the risk of stroke by at least five-fold and is associated with higher risk for mortality and morbidity. Therefore, prompt diagnosis and treatment is crucial. In addition to anti-coagulation therapy, electrical and pharmacological cardioversion to restore sinus rhythm remains the standard of care. The most common and effective method for electrical cardioversion is achieved with placement of electrodes in the anteroposterior position. CASE REPORT We present three cases of patients with initial unsuccessful cardioversion attempts for persistent atrial fibrillation. These patients had elevated body mass indices and large trans-thoracic diameters. Their initial external cardioversion via the conventional method was not successful for restoration of sinus rhythm. This failure may have been attributed to their body habitus. To ensure that the current would traverse through the atrial tissue, the electrode pads were applied using fluoroscopic guidance for adequate myocardial depolarization. CONCLUSIONS Optimal fluoroscopic placement of the electrode pads during external cardioversion procedure increases the odds of successful restoration of sinus rhythm when compared to the conventional method. PMID- 29445076 TI - Clinical Utility of Carotid Ultrasonography in the Prediction of Cardiovascular Events in Patients with Diabetes: A Combined Analysis of Data Obtained in Five Longitudinal Studies. AB - AIM: It remains unclear whether measures used in carotid ultrasonography such as the intima-media thickness (IMT) and ultrasonic tissue characterization of the carotid using the gray-scale median (GSM) can add prognostic information beyond the conventional cardiovascular risk markers in patients with diabetes. METHODS: This study employed a combined analysis of data obtained in five longitudinal studies including a total of 3263 patients with diabetes but without apparent cardiovascular disease (CVD) at baseline. The associations between carotid ultrasonography measures and the first occurrence of CVD (488 cases), which were defined as cardiovascular death, coronary artery diseases, stroke, or peripheral artery disease, were analyzed. RESULTS: Common carotid artery (CCA)-mean-IMT, CCA max-IMT, Max-IMT, plaque-GSM, and the presence of low-GSM echolucent plaques at baseline were prognostic factors for CVD even after adjustment for conventional risk factors. Time-dependent receiver-operating-characteristic (ROC) curve analysis indicated that the use of CCA-mean-IMT, CCA-max-IMT, and Max-IMT in addition to the conventional risk factors improved significantly the prediction of occurrence of CVD. Increments in the CCA-mean-IMT (hazard ratio [HR] 2.37 for every 0.1-mm/year increment [95% confidence interval [CI]: 1.63-3.47], p<0.001), Max-IMT (HR 1.51 for every 0.1-mm/year increment [95% CI: 1.07-2.14], p=0.020), and Mean-GSM (HR 0.22 for every 10-U/year increment [95% CI: 0.06-0.76], p=0.016) during the observation period were also prognostic factors for CVD even after adjusting for the baseline value of the respective measure. CONCLUSIONS: Addition of carotid ultrasonography measures to conventional risk factors significantly improved the stratification of patients by cardiovascular risk. Changes over time in carotid ultrasonography measures may be used as therapeutic outcome measures. PMID- 29445078 TI - miR-144 Potentially Suppresses Proliferation and Migration of Ovarian Cancer Cells by Targeting RUNX1. AB - BACKGROUND Ovarian cancer (OC) is one of the most common malignant diseases of the female reproductive system worldwide. Evidence has shown that microRNAs are involved in the development of ovarian cancer. miR-144, one of these microRNAs, has been found have upregulated expression in various human malignancies. The present study aimed to investigate the role miR-144 in ovarian cancer cell lines and to elucidate the mechanism involved. MATERIAL AND METHODS Human ovarian cancer cell lines (SKOV3/OVCAR3) and a normal ovarian cell line (IOSE80) were used to identify the miR-144 expression though qRT-PCR method. SKOV3/OVCAR3 cells were transfected with miR-144 mimics by Lipofectamine, and the proliferation, migration, and invasion ability of these cells were detected by MTT assay, wound healing assay, and Transwell assays, respectively. MMP2 and MMP9 expression were detected at mRNA and protein levels. The results of dual luciferase reporter assay confirmed that miR-144 could down-regulate RUNX1 expression level. Finally, the expression of runt-related transcription factor 1 (RUNX1) was examined using qRT-PCR and Western blot analysis. RESULTS Our results demonstrate that the expression level of miR-144 was downregulated in SKOV3/OVCAR3 compared to IOSE80, and we found that miR-144 suppresses the proliferation and migration of ovarian cancer cells. Moreover, RUNX1 was predicted and confirmed to be a target of miRNA 144. Additionally, after 48-h transfection with miR-144 mimics, the expression of RUNX1 was downregulated in OC cells. CONCLUSIONS miR-144 mimics can inhibit the proliferation and migration of ovarian cancer cells though regulating the expression of RUNX1. PMID- 29445079 TI - Seropositivity of Hepatitis A in Children Aged 7-14 Years in Diyarbakir Province Center. AB - BACKGROUND Hepatitis A virus (HAV) is a common morbidity in society, and mortality is more common in older ages. It is important to identify the prevalence in the population, the development of primary protection methods, and vaccination policies. This study aimed to identify anti-HAV seropositivity in children in 3 different schools in Diyarbakir, Turkey, to evaluate the risk factors influencing prevalence, and thus to develop strategies to prevent infection. MATERIAL AND METHODS The study was a prospective investigation of 600 children with a mean age of 10.5 years (range, 7-14), including 291 males and 309 females. RESULTS The seropositivity was 45.7% (41.2% in males and 49.8% females) with a statistically significant difference by sex (p=0.042). It was also significantly correlated with age. Factors significantly associated with seropositivity were educational level and income of parents, number of rooms in the house, type of toilet, number of siblings, and source of drinking water. Hence, older age, more siblings, crowded household, and low socioeconomic level are risk factors for seropositivity. CONCLUSIONS Protection strategies for the disease include improving socioeconomic level, increasing the level of education, disseminating appropriate drinking water, improving infrastructure and sewage disposal, and public health education on hygiene and the importance of vaccination. We also believe that active immunization against HAV in Turkey in general and in our province in particular can prevent infection in children and related complications in older people. PMID- 29445080 TI - Modeling radiation injury-induced cell death and countermeasure drug responses in a human Gut-on-a-Chip. AB - Studies on human intestinal injury induced by acute exposure to gamma-radiation commonly rely on use of animal models because culture systems do not faithfully mimic human intestinal physiology. Here we used a human Gut-on-a-Chip (Gut Chip) microfluidic device lined by human intestinal epithelial cells and vascular endothelial cells to model radiation injury and assess the efficacy of radiation countermeasure drugs in vitro. Exposure of the Gut Chip to gamma-radiation resulted in increased generation of reactive oxygen species, cytotoxicity, apoptosis, and DNA fragmentation, as well as villus blunting, disruption of tight junctions, and compromise of intestinal barrier integrity. In contrast, pre treatment with a potential prophylactic radiation countermeasure drug, dimethyloxaloylglycine (DMOG), significantly suppressed all of these injury responses. Thus, the human Gut Chip may serve as an in vitro platform for studying radiation-induced cell death and associate gastrointestinal acute syndrome, in addition to screening of novel radio-protective medical countermeasure drugs. PMID- 29445081 TI - Baicalin administration attenuates hyperglycemia-induced malformation of cardiovascular system. AB - In this study, the effects of Baicalin on the hyperglycemia-induced cardiovascular malformation during embryo development were investigated. Using early chick embryos, an optimal concentration of Baicalin (6 MUM) was identified which could prevent hyperglycemia-induced cardiovascular malformation of embryos. Hyperglycemia-enhanced cell apoptosis was reduced in embryos and HUVECs in the presence of Baicalin. Hyperglycemia-induced excessive ROS production was inhibited when Baicalin was administered. Analyses of SOD, GSH-Px, MQAE and GABAA suggested Baicalin plays an antioxidant role in chick embryos possibly through suppression of outwardly rectifying Cl(-) in the high-glucose microenvironment. In addition, hyperglycemia-enhanced autophagy fell in the presence of Baicalin, through affecting the ubiquitin of p62 and accelerating autophagy flux. Both Baicalin and Vitamin C could decrease apoptosis, but CQ did not, suggesting autophagy to be a protective function on the cell survival. In mice, Baicalin reduced the elevated blood glucose level caused by streptozotocin (STZ). Taken together, these data suggest that hyperglycemia-induced embryonic cardiovascular malformation can be attenuated by Baicalin administration through suppressing the excessive production of ROS and autophagy. Baicalin could be a potential candidate drug for women suffering from gestational diabetes mellitus. PMID- 29445082 TI - Pyruvate kinase M2 regulates photoreceptor structure, function, and viability. AB - Pyruvate kinase M2 (PKM2) is a glycolytic enzyme that is expressed in cancer cells. Its role in tumor metabolism is not definitively established, but investigators have suggested that regulation of PKM2 activity can cause accumulation of glycolytic intermediates and increase flux through the pentose phosphate pathway. Recent evidence suggests that PKM2 also may have non-metabolic functions, including as a transcriptional co-activator in gene regulation. We reported previously that PKM2 is abundant in photoreceptor cells in mouse retinas. In the present study, we conditionally deleted PKM2 (rod-cre PKM2-KO) in rod photoreceptors and found that the absence of PKM2 causes increased expression of PKM1 in rods. Analysis of metabolic flux from U-13C glucose shows that rod-cre PKM2-KO retinas accumulate glycolytic intermediates, consistent with an overall reduction in the amount of pyruvate kinase activity. Rod-cre PKM2-KO mice also have an increased NADPH availability could favor lipid synthesis, but we found no difference in phospholipid synthesis between rod-cre PKM2 KO and PKM2-positive controls. As rod-cre PKM2-KO mice aged, we observed a significant loss of rod function, reduced thickness of the photoreceptor outer segment layer, and reduced expression of photoreceptor proteins, including PDE6beta. The rod-cre PKM2-KO retinas showed greater TUNEL staining than wild-type retinas, indicating a slow retinal degeneration. In vitro analysis showed that PKM2 can regulate transcriptional activity from the PDE6beta promoter in vitro. Our findings indicate that both the metabolic and transcriptional regulatory functions of PKM2 may contribute to photoreceptor structure, function, and viability. PMID- 29445083 TI - Fibroblast growth factor-21 prevents diabetic cardiomyopathy via AMPK-mediated antioxidation and lipid-lowering effects in the heart. AB - Our previous studies showed that both exogenous and endogenous FGF21 inhibited cardiac apoptosis at the early stage of type 1 diabetes. Whether FGF21 induces preventive effect on type 2 diabetes-induced cardiomyopathy was investigated in the present study. High-fat-diet/streptozotocin-induced type 2 diabetes was established in both wild-type (WT) and FGF21-knockout (FGF21-KO) mice followed by treating with FGF21 for 4 months. Diabetic cardiomyopathy (DCM) was diagnosed by significant cardiac dysfunction, remodeling, and cardiac lipid accumulation associated with increased apoptosis, inflammation, and oxidative stress, which was aggravated in FGF21-KO mice. However, the cardiac damage above was prevented by administration of FGF21. Further studies demonstrated that the metabolic regulating effect of FGF21 is not enough, contributing to FGF21-induced significant cardiac protection under diabetic conditions. Therefore, other protective mechanisms must exist. The in vivo cardiac damage was mimicked in primary neonatal or adult mouse cardiomyocytes treated with HG/Pal, which was inhibited by FGF21 treatment. Knockdown of AMPKalpha1/2, AKT2, or NRF2 with their siRNAs revealed that FGF21 protected cardiomyocytes from HG/Pal partially via upregulating AMPK-AKT2-NRF2-mediated antioxidative pathway. Additionally, knockdown of AMPK suppressed fatty acid beta-oxidation via inhibition of ACC-CPT 1 pathway. And, inhibition of fatty acid beta-oxidation partially blocked FGF21 induced protection in cardiomyocytes. Further, in vitro and in vivo studies indicated that FGF21-induced cardiac protection against type 2 diabetes was mainly attributed to lipotoxicity rather than glucose toxicity. These results demonstrate that FGF21 functions physiologically and pharmacologically to prevent type 2 diabetic lipotoxicity-induced cardiomyopathy through activation of both AMPK-AKT2-NRF2-mediated antioxidative pathway and AMPK-ACC-CPT-1-mediated lipid lowering effect in the heart. PMID- 29445085 TI - Glycogen synthase kinase-3beta inhibition promotes lysosome-dependent degradation of c-FLIPL in hepatocellular carcinoma. AB - Glycogen synthase kinase-3beta (GSK-3beta) is a ubiquitously expressed serine/threonine kinase involved in a variety of functions ranging from the control of glycogen metabolism to transcriptional regulation. We recently demonstrated that GSK-3beta inhibition triggered ASK1-JNK-dependent apoptosis in human hepatocellular carcinoma (HCC) cells. However, the comprehensive picture of downstream GSK-3beta-regulated pathways/functions remains elusive. In this study, we showed that GSK-3beta was aberrantly activated in HCC. Pharmacological inhibition and genetic depletion of GSK-3beta suppressed the growth and induced caspase-dependent apoptosis in HCC cells. In addition, GSK-3beta inhibition induced apoptosis through downregulation of c-FLIPL in HCC, which was caused by biogenesis of functional lysosomes and subsequently c-FLIPL translocated to lysosome for degradation. This induction of the lysosome-dependent c-FLIPL degradation was associated with nuclear translocation of transcription factor EB (TFEB), a master regulator of lysosomal biogenesis. Moreover, GSK-3beta inhibition-induced TFEB translocation acts through activation of AMPK and subsequently suppression of mTOR activity. Thus our findings reveal a novel mechanism by which inhibition of GSK-3beta promotes lysosome-dependent degradation of c-FLIPL. Our study shows that GSK-3beta may become a promising therapeutic target for HCC. PMID- 29445084 TI - The carnitine system and cancer metabolic plasticity. AB - Metabolic flexibility describes the ability of cells to respond or adapt its metabolism to support and enable rapid proliferation, continuous growth, and survival in hostile conditions. This dynamic character of the cellular metabolic network appears enhanced in cancer cells, in order to increase the adaptive phenotype and to maintain both viability and uncontrolled proliferation. Cancer cells can reprogram their metabolism to satisfy the energy as well as the biosynthetic intermediate request and to preserve their integrity from the harsh and hypoxic environment. Although several studies now recognize these reprogrammed activities as hallmarks of cancer, it remains unclear which are the pathways involved in regulating metabolic plasticity. Recent findings have suggested that carnitine system (CS) could be considered as a gridlock to finely trigger the metabolic flexibility of cancer cells. Indeed, the components of this system are involved in the bi-directional transport of acyl moieties from cytosol to mitochondria and vice versa, thus playing a fundamental role in tuning the switch between the glucose and fatty acid metabolism. Therefore, the CS regulation, at both enzymatic and epigenetic levels, plays a pivotal role in tumors, suggesting new druggable pathways for prevention and treatment of human cancer. PMID- 29445086 TI - The oncogene Etv5 promotes MET in somatic reprogramming and orchestrates epiblast/primitive endoderm specification during mESCs differentiation. AB - Unipotent spermatogonial stem cells (SSCs) can be efficiently reprogrammed into pluripotent stem cells only by manipulating the culture condition, without introducing exogenous reprogramming factors. This phenotype raises the hypothesis that the endogenous transcription factors (TFs) in SSCs may facilitate reprogramming to acquire pluripotency. In this study, we screened a pool of SSCs TFs (Bcl6b, Lhx1, Foxo1, Plzf, Id4, Taf4b, and Etv5), and found that oncogene Etv5 could dramatically increase the efficiency of induced pluripotent stem cells (iPSCs) generation when combined with Yamanaka factors. We also demonstrated that Etv5 could promote mesenchymal-epithelial transition (MET) at the early stage of reprogramming by regulating Tet2-miR200s-Zeb1 axis. In addition, Etv5 knockdown in mouse embryonic stem cells (mESCs) could decrease the genomic 5hmC level by downregulating Tet2. Furthermore, the embryoid body assay revealed that Etv5 could positively regulate primitive endoderm specification through regulating Gata6 and negatively regulate epiblast specification by inhibiting Fgf5 expression. In summary, our findings provide insights into understanding the regulation mechanisms of Etv5 under the context of somatic reprogramming, mESCs maintenance, and differentiation. PMID- 29445087 TI - Rage induces hepatocellular carcinoma proliferation and sorafenib resistance by modulating autophagy. AB - The receptor for advanced glycation end products (Rage) is involved in the development of various tumors and acts as an oncogenic protein. Rage is overexpressed in tumors including hepatocellular carcinoma (HCC). However, the molecular mechanism of Rage in HCC progression and sorafenib resistance remains unclear. In this study, enhanced Rage expression is highly associated proliferation and contributes to sorafenib resistance. Rage deficiency contributed to autophagy induction through activating AMPK/mTOR signaling pathway, which is important for sorafenib response. Moreover, the interactions between Rage and Rage ligands such as high mobility group box 1 (HMGB1) and s100a4 positively increased Rage expression. Our data indicate that Rage may be a potential target for therapeutic intervention in HCC and biomarker for sorafenib resistance. PMID- 29445088 TI - Cancer cell responses to Hsp70 inhibitor JG-98: Comparison with Hsp90 inhibitors and finding synergistic drug combinations. AB - Hsp70 is a promising anti-cancer target. Our JG-98 series of Hsp70 inhibitors show anti-cancer activities affecting both cancer cells and tumor-associated macrophages. They disrupt Hsp70 interaction with a co-chaperone Bag3 and affect signaling pathways important for cancer development. Due to a prior report that depletion of Hsp70 causes similar responses as depletion of Hsp90, interest to Hsp70 inhibitors as drug prototypes is hampered by potential similarity of their effects to effects of Hsp90 inhibitors. Here, using the Connectivity Map platform we demonstrate that physiological effects of JG-98 are dissimilar from effects of Hsp90 inhibitors, thus justifying development of these compounds. Using gene expression and ActivSignal IPAD platform, we identified pathways modulated by JG 98. Some of these pathways were affected by JG-98 in Bag3-dependent (e.g. ERK) and some in Bag3-independent manner (e.g. Akt or c-myc), indicating multiple effects of Hsp70 inhibition. Further, we identified genes that modulate cellular responses to JG-98, developed approaches to predict potent combinations of JG-98 with known drugs, and demonstrated that inhibitors of proteasome, RNApol, Akt and RTK synergize with JG-98. Overall, here we established unique effects of novel Hsp70 inhibitors on cancer cell physiology, and predicted potential drug combinations for pre-clinical development. PMID- 29445089 TI - MiR-27a-5p Increases Steer Fat Deposition Partly by Targeting Calcium-sensing Receptor (CASR). AB - Castration increases fat deposition, improving beef quality in cattle. Here, the steer group exhibited a significantly higher intramuscular fat (IMF) content than the bull group. To determine the potential roles of microRNAs (miRNAs) in castration-induced fat deposition, differential expression patterns of miRNA in liver tissue were investigated in bulls and steers. A total of 7,827,294 clean reads were obtained from the bull liver library, and 8,312,483 were obtained from the steer liver library; 452 conserved bovine miRNAs and 20 novel miRNAs were identified. The results showed that the expression profiles of miRNA in liver tissue were changed by castration, and 12 miRNAs that were differentially expressed between bulls and steers were identified. Their target genes were majorly involved in the metabolic, PI3K-Akt, and MAPK signaling pathways. Furthermore, six differentially expressed miRNAs were validated by quantitative real-time PCR, and luciferase reporter assays verified that calcium-sensing receptor (CASR) was the direct target of miR-27a-5p. Meantime, we found that the expression level of CASR was significantly higher in steers than in bulls, and revealed that CASR gene silencing in bovine hepatocytes significantly inhibited triacylglycerol (TAG) accumulation and reduced secretion of very low density lipoprotein (VLDL). These results obtained in the liver indicate that miR-27a-5p may increase fat deposition partly by targeting CASR in steers. PMID- 29445090 TI - Two Sprayer CVD Synthesis of Nitrogen-doped Carbon Sponge-type Nanomaterials. AB - Nitrogen-doped carbon sponge-type nanostructures (N-CSTNs) containing coaxial multiwalled carbon nanotubes are synthesized at 1020 degrees C by using a modified chemical vapor deposition (CVD) arrangement. Here, the CVD reactor is supplied by two flows coming from two independent sprayers (called sprayer A and sprayer B). The nebulized material in each sprayer is transported by two different gases with different flow velocities. The synthesis of carbon N-CSTNs is performed using different precursors: sprayer A contains a solution composed of ethanol, thiophene and ferrocene, whereas sprayer B contains a solution of benzylamine, thiophene and ferrocene. Samples are classified according to the position inside the reactor and characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy and thermogravimetric analysis (TGA). Samples collected at the beginning of the reactor contain curly structures with diameters of 10-100 nm. At the end of the reactor, the sample is mainly formed by one type of structure. A spongy-type material is mainly formed in the hottest zone of the tubular furnace. The N-CSTNs are highly hydrophobic with oil sorption properties, which could be used for adsorption of oil spills. PMID- 29445091 TI - Thermal stabilization of the deglycating enzyme Amadoriase I by rational design. AB - Amadoriases are a class of FAD-dependent enzymes that are found in fungi, yeast and bacteria and that are able to hydrolyze glycated amino acids, cleaving the sugar moiety from the amino acidic portion. So far, engineered Amadoriases have mostly found practical application in the measurement of the concentration of glycated albumin in blood samples. However, these engineered forms of Amadoriases show relatively low absolute activity and stability levels, which affect their conditions of use. Therefore, enzyme stabilization is desirable prior to function altering molecular engineering. In this work, we describe a rational design strategy based on a computational screening method to evaluate a library of potentially stabilizing disulfide bonds. Our approach allowed the identification of two thermostable Amadoriase I mutants (SS03 and SS17) featuring a significantly higher T50 (55.3 degrees C and 60.6 degrees C, respectively) compared to the wild-type enzyme (52.4 degrees C). Moreover, SS17 shows clear hyperstabilization, with residual activity up to 95 degrees C, whereas the wild type enzyme is fully inactive at 55 degrees C. Our computational screening method can therefore be considered as a promising approach to expedite the design of thermostable enzymes. PMID- 29445092 TI - 3D Plasmon Coupling Assisted Sers on Nanoparticle-Nanocup Array Hybrids. AB - Unique colorimetric optical properties of nanomaterials can effectively influence the light absorption or emission of molecules. Here, we design plasmonic substrate for surface-enhanced Raman scattering (SERS) by inducing three dimensional (3D) hot spots on the sensing surface. The 3D hot spots are formed by the self-assembly of plasmonic nanoparticles (NPs) on a 3D plasmonic nanocup array structure. This 3D hot spot formation on the periodic nanocup arrays achieves much higher SERS enhancement factor than the 2D NP arrays, which have been conventionally sought SERS substrates. We also utilize the colorimetric properties of the nanocup arrays for an additional degree of SERS enhancement. Colorimetry, achieved by tunable plasmon resonance wavelength by controlling dielectric property on the nanocup array surface, eases the modulation of the plasmonic resonance condition without modifying the nanostructure design. By continuously monitoring the shifts of the plasmon resonance condition and its effect on the light absorption and emission of the nearby molecules, we verify that larger SERS enhancement is achieved when the plasmon resonance wavelength is matched with the Raman excitation wavelength. The ease of plasmon resonance tuning of this nanocup array-nanoparticle hybrid structure allows versatile SERS enhancement for a variety of different Raman measurement conditions. PMID- 29445093 TI - Hydroxynitrile lyases from cyanogenic millipedes: molecular cloning, heterologous expression, and whole-cell biocatalysis for the production of (R)-mandelonitrile. AB - Hydroxynitrile lyases (HNLs), which are key enzymes in cyanogenesis, catalyze the cleavage of cyanohydrins into carbonyl compounds and hydrogen cyanide. Since HNLs also catalyze the reverse reaction, they are used industrially for the asymmetric synthesis of cyanohydrins, which are valuable building blocks of pharmaceuticals and fine chemicals. HNLs have been isolated from cyanogenic plants and bacteria. Recently, an HNL from the cyanogenic millipede Chamberlinius hualienensis was shown to have the highest specific activity for (R)-mandelonitrile synthesis, along with high stability and enantioselectivity. However, no HNLs have been isolated from other cyanogenic millipedes. We identified and characterized HNLs from 10 cyanogenic millipedes in the Paradoxosomatidae and Xystodesmidae. Sequence analyses showed that HNLs are conserved among cyanogenic millipedes and likely evolved from one ancestral gene. The HNL from Parafontaria tonominea was expressed in Escherichia coli SHuffle T7 and showed high specific activity for (R)-mandelonitrile synthesis and stability at a range of pHs and temperatures. The stability of millipede HNLs is likely due to disulfide bond(s). The E. coli cells expressing HNL produced (R)-mandelonitrile with 97.6% enantiomeric excess without organic solvents. These results demonstrate that cyanogenic millipedes are a valuable source of HNLs with high specific activity and stability. PMID- 29445094 TI - Being slightly overweight is associated with a better quality of life in breast cancer survivors. AB - To examine the association between BMI and QOL in breast cancer survivors in China, we conducted a cross-sectional survey and recruited 10708 breast cancer survivors. Survivors self-reported QOL was measured using the EORTC QLQ-C30 and the QLQ-BR23. The impact of BMI on QOL was examined through standard least squares regression. Normal weight and overweight survivors were more likely to have a better QOL than underweight and obese survivors and the results were similar to survivors diagnosed as having chronic diseases. After adjustment for clinical and sociodemographic factors, the QOL increased with increasing BMI in breast cancer survivors ranged from underweight to overweight with no chronic diseases, especially in the scales of emotional function and fatigue. Obese breast cancer survivors reported a significantly worse QOL compared to normal weight and overweight breast cancer survivors. Within breast cancer survivors with one or more chronic diseases, it was more obvious that overweight ones had a significantly better QOL with clear evidence of a dose relationship across underweight to overweight in almost all scales. Unlike obese breast cancer survivors without chronic diseases, the ones with chronic disease(s) had a similar QOL compared to normal weight breast cancer survivors in all scales except in the domain of fatigue. PMID- 29445095 TI - Granzyme B deficiency promotes osteoblastic differentiation and calcification of vascular smooth muscle cells in hypoxic pulmonary hypertension. AB - Calcification is a major risk factor for vascular integrity. This pathological symptom and the underlying mechanisms in hypoxic pulmonary artery hypertension remain elusive. Here we report that pulmonary vascular medial calcification is elevated in pulmonary artery hypertension models as a result of an osteoblastic phenotype change of pulmonary arterial smooth muscle cells induced by hypoxia. Notably, inhibiting store-operated calcium channels significantly decreased osteoblastic differentiation and calcification of pulmonary arterial smooth muscle cells under hypoxia. We identified granzyme B, a major constituent of cytotoxic T lymphocytes/natural killer cell granules involved in apoptosis, as the main regulator of pulmonary arterial calcification. Overexpression of granzyme B blocked the mineralization through its effect on store-operated calcium channels in cultured pulmonary arterial smooth muscle cells under hypoxic conditions. Mice with overexpression of granzyme B exposed to hypoxia for 3 weeks showed attenuated vascular calcification and pathological progression of hypoxic pulmonary arterial hypertension. Our findings emphasize the central function of granzyme B in coordinating vascular calcification in hypoxic pulmonary arterial hypertension. PMID- 29445096 TI - Chronic intermittent hypoxia promotes myocardial ischemia-related ventricular arrhythmias and sudden cardiac death. AB - We investigated the effects of intermittent hypoxia (IH), such as that encountered in severe obstructive sleep apnea (OSA) patients, on the development and severity of myocardial ischemia-related ventricular arrhythmias. Rats were exposed to 14 days of IH (30 s at 5%O2 and 30 s at 21%O2, 8 h.day-1) or normoxia (N, similar air-air cycles) and submitted to a 30-min coronary ligature. Arterial blood pressure (BP) and ECG were recorded for power spectral analysis, ECG interval measurement and arrhythmia quantification. Left ventricular monophasic action potential duration (APD) and expression of L-type calcium (LTCC) and transient receptor potential (TRPC) channels were assessed in adjacent epicardial and endocardial sites. Chronic IH enhanced the incidence of ischemic arrhythmias, in particular ventricular fibrillation (66.7% vs. 33.3% in N rats, p < 0.05). IH also increased BP and plasma norepinephine levels along with increased low frequency (LF), decreased high-frequency (HF) and increased LF/HF ratio of heart rate and BP variability. IH prolonged QTc and Tpeak-to-Tend intervals, increased the ventricular APD gradient and upregulated endocardial but not epicardial LTCC, TRPC1 and TRPC6 (p < 0.05). Chronic IH, is a major risk factor for sudden cardiac death upon myocardial ischemia through sympathoactivation and alterations in ventricular repolarization, transmural APD gradient and endocardial calcium channel expression. PMID- 29445097 TI - Complete Transcriptome Profiling of Normal and Age-Related Macular Degeneration Eye Tissues Reveals Dysregulation of Anti-Sense Transcription. AB - Age-related macular degeneration (AMD) predominantly affects the retina and retinal pigment epithelium in the posterior eye. While there are numerous studies investigating the non-coding transcriptome of retina and RPE, few significant differences between AMD and normal tissues have been reported. Strand specific RNA sequencing of both peripheral retina (PR) and RPE-Choroid-Sclera (PRCS), in both AMD and matched normal controls were generated. The transcriptome analysis reveals a highly significant and consistent impact on anti-sense transcription as well as moderate changes in the regulation of non-coding (sense) RNA. Hundreds of genes that do not express anti-sense transcripts in normal PR and PRCS demonstrate significant anti-sense expression in AMD in all patient samples. Several pathways are highly enriched in the upregulated anti-sense transcripts-in particular the EIF2 signaling pathway. These results call for a deeper exploration into anti-sense and noncoding RNA regulation in AMD and their potential as therapeutic targets. PMID- 29445098 TI - Representational similarity analysis reveals task-dependent semantic influence of the visual word form area. AB - Access to semantic information of visual word forms is a key component of reading comprehension. In this study, we examined the involvement of the visual word form area (VWFA) in this process by investigating whether and how the activity patterns of the VWFA are influenced by semantic information during semantic tasks. We asked participants to perform two semantic tasks - taxonomic or thematic categorization - on visual words while obtaining the blood-oxygen-level dependent (BOLD) fMRI responses to each word. Representational similarity analysis with four types of semantic relations (taxonomic, thematic, subjective semantic rating and word2vec) revealed that neural activity patterns of the VWFA were associated with taxonomic information only in the taxonomic task, with thematic information only in the thematic task and with the composite semantic information measured by word2vec in both semantic tasks. Furthermore, the semantic information in the VWFA cannot be explained by confounding factors including orthographic, low-level visual and phonological information. These findings provide positive evidence for the presence of both orthographic and task relevant semantic information in the VWFA and have significant implications for the neurobiological basis of reading. PMID- 29445099 TI - Pharmacokinetic-pharmacodynamic correlations in the development of ginger extract as an anticancer agent. AB - Anticancer efficacy of ginger phenolics (GPs) has been demonstrated in various in vitro assays and xenograft mouse models. However, only sub-therapeutic plasma concentrations of GPs were detected in human and mouse pharmacokinetic (PK) studies. Intriguingly, a significant portion of GPs occurred as phase II metabolites (mainly glucuronide conjugates) in plasma. To evaluate the disposition of GPs and understand the real players responsible for efficacy, we performed a PK and tissue distribution study in mice. Plasma exposure of GPs was similar on day 1 and 7, suggesting no induction or inhibition of clearance pathways. Both free and conjugated GPs accumulated in all tissues including tumors. While non-cytotoxicity of 6-ginerol glucuronide precluded the role of conjugated GPs in cell death, the free forms were cytotoxic against prostate cancer cells. The efficacy of ginger was best explained by the reconversion of conjugated GPs to free forms by beta-glucuronidase, which is over-expressed in the tumor tissue. This previously unrecognized two-step process suggests an instantaneous conversion of ingested free GPs into conjugated forms, followed by their subsequent absorption into systemic circulation and reconversion into free forms. This proposed model uncovers the mechanistic underpinnings of ginger's anticancer activity despite sub-therapeutic levels of free GPs in the plasma. PMID- 29445100 TI - Pretreatment Inflammatory Indexes as Prognostic Predictors for Survival in Colorectal Cancer Patients Receiving Neoadjuvant Chemoradiotherapy. AB - This study was to evaluate the prognostic value of pretreatment inflammatory indexes including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), and systemic immune-inflammation index (SII) in colorectal cancer (CRC) patients receiving neoadjuvant chemoradiotherapy (CRT). We enrolled 98 eligible CRC patients and divided them into high or low NLR, PLR, LMR, and SII groups according to their median index value, respectively. Univariate and multivariate analysis were performed to identify the potential predictors of progression-free survival (PFS) and overall survival (OS). In the univariate analysis, ECOG performance status, distant metastasis, NLR, PLR, LMR, and SII were found to be significantly associated with PFS and OS. In the multivariate analysis, ECOG performance status, distant metastasis, and NLR were identified to be independent predictors of PFS (HR 2.487, p = 0.012; HR 2.422, p = 0.042; HR 2.243, p = 0.034, respectively), and OS (HR 2.237, p = 0.018; HR 2.757, p = 0.020; HR 2.336, p = 0.017, respectively). The results of our study revealed that ECOG performance status, distant metastasis and NLR were independent prognostic factors of PFS and OS in CRC patients receiving neoadjuvant CRT. PMID- 29445101 TI - Projective measurement onto arbitrary superposition of weak coherent state bases. AB - One of the peculiar features in quantum mechanics is that a superposition of macroscopically distinct states can exist. In optical system, this is highlighted by a superposition of coherent states (SCS), i.e. a superposition of classical states. Recently this highly nontrivial quantum state and its variant have been demonstrated experimentally. Here we demonstrate the superposition of coherent states in quantum measurement which is also a key concept in quantum mechanics. More precisely, we propose and implement a projection measurement onto an arbitrary superposition of two weak coherent states in optical system. The measurement operators are reconstructed experimentally by a novel quantum detector tomography protocol. Our device is realized by combining the displacement operation and photon counting, well established technologies, and thus has implications in various optical quantum information processing applications. PMID- 29445103 TI - Mesoscopic physical removal of material using sliding nano-diamond contacts. AB - Wear mechanisms including fracture and plastic deformation at the nanoscale are central to understand sliding contacts. Recently, the combination of tip-induced material erosion with the sensing capability of secondary imaging modes of AFM, has enabled a slice-and-view tomographic technique named AFM tomography or Scalpel SPM. However, the elusive laws governing nanoscale wear and the large quantity of atoms involved in the tip-sample contact, require a dedicated mesoscale description to understand and model the tip-induced material removal. Here, we study nanosized sliding contacts made of diamond in the regime whereby thousands of nm3 are removed. We explore the fundamentals of high-pressure tip induced material removal for various materials. Changes in the load force are systematically combined with AFM and SEM to increase the understanding and the process controllability. The nonlinear variation of the removal rate with the load force is interpreted as a combination of two contact regimes each dominating in a particular force range. By using the gradual transition between the two regimes, (1) the experimental rate of material eroded on each tip passage is modeled, (2) a controllable removal rate below 5 nm/scan for all the materials is demonstrated, thus opening to future development of 3D tomographic AFM. PMID- 29445102 TI - Reversal of stress fibre formation by Nitric Oxide mediated RhoA inhibition leads to reduction in the height of preformed thrombi. AB - Evidence has emerged to suggest that thrombi are dynamic structures with distinct areas of differing platelet activation and inhibition. We hypothesised that Nitric oxide (NO), a platelet inhibitor, can modulate the actin cytoskeleton reversing platelet spreading, and therefore reduce the capability of thrombi to withstand a high shear environment. Our data demonstrates that GSNO, DEANONOate, and a PKG-activating cGMP analogue reversed stress fibre formation and increased actin nodule formation in adherent platelets. This effect is sGC dependent and independent of ADP and thromboxanes. Stress fibre formation is a RhoA dependent process and NO induced RhoA inhibition, however, it did not phosphorylate RhoA at ser188 in spread platelets. Interestingly NO and PGI2 synergise to reverse stress fibre formation at physiologically relevant concentrations. Analysis of high shear conditions indicated that platelets activated on fibrinogen, induced stress fibre formation, which was reversed by GSNO treatment. Furthermore, preformed thrombi on collagen post perfused with GSNO had a 30% reduction in thrombus height in comparison to the control. This study demonstrates that NO can reverse key platelet functions after their initial activation and identifies a novel mechanism for controlling excessive thrombosis. PMID- 29445104 TI - Genetic modification to induce CXCR2 overexpression in mesenchymal stem cells enhances treatment benefits in radiation-induced oral mucositis. AB - Radiation-induced oral mucositis affects patient quality of life and reduces tolerance to cancer therapy. Unfortunately, traditional treatments are insufficient for the treatment of mucositis and might elicit severe side effects. Due to their immunomodulatory and anti-inflammatory properties, the transplantation of mesenchymal stem cells (MSCs) is a potential therapeutic strategy for mucositis. However, systemically infused MSCs rarely reach inflamed sites, impacting their clinical efficacy. Previous studies have demonstrated that chemokine axes play an important role in MSC targeting. By systematically evaluating the expression patterns of chemokines in radiation/chemical-induced oral mucositis, we found that CXCL2 was highly expressed, whereas cultured MSCs negligibly express the CXCL2 receptor CXCR2. Thus, we explored the potential therapeutic benefits of the transplantation of CXCR2-overexpressing MSCs (MSCsCXCR2) for mucositis treatment. Indeed, MSCsCXCR2 exhibited enhanced targeting ability to the inflamed mucosa in radiation/chemical-induced oral mucositis mouse models. Furthermore, we found that MSCCXCR2 transplantation accelerated ulcer healing by suppressing the production of pro-inflammatory chemokines and radiogenic reactive oxygen species (ROS). Altogether, these findings indicate that CXCR2 overexpression in MSCs accelerates ulcer healing, providing new insights into cell-based therapy for radiation/chemical-induced oral mucositis. PMID- 29445105 TI - Presence-absence of marine macrozoobenthos does not generally predict abundance and biomass. AB - Many monitoring programmes of species abundance and biomass increasingly face financial pressures. Occupancy is often easier and cheaper to measure than abundance or biomass. We, therefore, explored whether measuring occupancy is a viable alternative to measuring abundance and biomass. Abundance- or biomass occupancy relationships were studied for sixteen macrozoobenthos species collected across the entire Dutch Wadden Sea in eight consecutive summers. Because the form and strength of these relationships are scale-dependent, the analysis was completed at different spatiotemporal scales. Large differences in intercept and slope of abundance- or biomass-occupancy relationships were found. Abundance, not biomass, was generally positively correlated with occupancy. Only at the largest scale, seven species showed reasonably strong abundance-occupancy relationships with large coefficients of determination and small differences in observed and predicted values (RMSE). Otherwise, and at all the other scales, intraspecific abundance and biomass relationships were poor. Our results showed that there is no generic relationship between a species' abundance or biomass and its occupancy. We discuss how ecological differences between species could cause such large variation in these relationships. Future technologies might allow estimating a species' abundance or biomass directly from eDNA sampling data, but for now, we need to rely on traditional sampling technology. PMID- 29445106 TI - The High-Pressure Superconducting Phase of Arsenic. AB - Ab initio random structure searching (AIRSS) technique is predicted a stable structure of arsenic (As). We find that the body-centered tetragonal (bct) structure with spacegroup I41/acd to be the stable structure at high pressure. Our calculation suggests transition sequence from the simple cubic (sc) structure transforms into the host-guest (HG) structure at 41 GPa and then into the bct structure at 81 GPa. The bct structure has been calculated using ab initio lattice dynamics with finite displacement method confirm the stability at high pressure. The spectral function alpha2F of the bct structure is higher than those of the body-centered cubic (bcc) structure. It is worth noting that both bct and bcc structures share the remarkable similarity of structural and property. Here we have reported the prediction of temperature superconductivity of the bct structure, with a T c of 4.2 K at 150 GPa. PMID- 29445107 TI - Progesterone Receptor Membrane Component 1 suppresses the p53 and Wnt/beta catenin pathways to promote human pluripotent stem cell self-renewal. AB - Progesterone receptor membrane component 1 (PGRMC1) is a multifunctional heme binding protein involved in various diseases, including cancers and Alzheimer's disease. Previously, we generated two monoclonal antibodies (MAbs) 108-B6 and 4A68 against surface molecules on human pluripotent stem cells (hPSCs). Here we show that PGRMC1 is the target antigen of both MAbs, and is predominantly expressed on hPSCs and some cancer cells. PGRMC1 is rapidly downregulated during early differentiation of hPSCs. Although PGRMC1 knockdown leads to a spread-out morphology and impaired self-renewal in hPSCs, PGRMC1 knockdown hPSCs do not show apoptosis and autophagy. Instead, PGRMC1 knockdown leads to differentiation of hPSCs into multiple lineage cells without affecting the expression of pluripotency markers. PGRMC1 knockdown increases cyclin D1 expression and decreases Plk1 expression in hPSCs. PGRMC1 knockdown also induces p53 expression and stability, suggesting that PGRMC1 maintains hPSC self-renewal through suppression of p53-dependent pathway. Analysis of signaling molecules further reveals that PGRMC1 knockdown promotes inhibitory phosphorylation of GSK-3beta and increased expression of Wnt3a and beta-catenin, which leads to activation of Wnt/beta-catenin signaling. The results suggest that PGRMC1 suppresses the p53 and Wnt/beta-catenin pathways to promote self-renewal and inhibit early differentiation in hPSCs. PMID- 29445108 TI - Individual and combined effects of herbicide tribenuron-methyl and fungicide tebuconazole on soil earthworm Eisenia fetida. AB - Earthworms are soil engineers that alter the soil bio-physical properties to favor plant growth whereas pesticides represent a significant threat to their abundance and soil health. Thus, we investigated the toxic effects of tribenuron methyl (TBM) and tebuconazole (TEB) on the soil earthworm, Eisenia fetida. The TBM demonstrated low toxicity to E. fetida in the contact filter paper and artificial soil tests, with median lethal concentrations (LC50) of 135.6 MUg cm-2 at 48 h and 511 mg kg-1 on day 14, respectively. Similarly, TEB also showed low toxicity to E. fetida in the artificial soil test with LC50 of 287 mg kg-1 on day 14. However, TEB was highly toxic to earthworm in the contact filter paper test with LC50 of 5.7 MUg cm-2 at 48 h. The mixture of two pesticides had an antagonistic effect on the earthworm. Under 0.1 LC50 of TBM and TEB, either single or combined application of pesticides induced oxidative stress and inhibited cellulase activity in early days of the earthworm exposure. However, both pesticides did not damage the earthworm DNA. Our results suggest that pesticides can negatively affect soil earthworms and provide valuable information regarding the responses of soil biological engineers to the lethal agrochemicals. PMID- 29445109 TI - Species-specified VOC emissions derived from a gridded study in the Pearl River Delta, China. AB - This study provides a top-down approach to establish an emission inventory of volatile organic compounds (VOC) based on ambient measurements, by combining the box model and positive matrix factorization (PMF) model. Species-specified VOC emissions, source contributions, and spatial distributions are determined based on regional-scale gridded measurements between September 2008 to December 2009 in the Pearl River Delta (PRD), China. The most prevalent anthropogenic species in the PRD was toluene estimated by the box model to be annual emissions of 167.8 +/ 100.5 Gg, followed by m,p-xylene (68.0 +/- 45.0 Gg), i-pentane (49.2 +/- 40.0 Gg), ethene (47.6 +/- 27.6 Gg), n-butane (47.5 +/- 40.7 Gg), and benzene (46.8 +/ 29.0 Gg). Alkanes such as propane, i-butane, and n-pentane were 2-8 times higher in box model than emission inventories (EI). Species with fewer emissions were highly variable between EI and box model results. Hotspots of VOC emissions were identified in southwestern PRD and port areas, which were not reflected by bottom up EI. This suggests more research is needed for VOC emissions in the EI, especially for fuel evaporation, industrial operations and marine vessels. The species-specified top-down method can help improve the quality of these emission inventories.

AB - Environmental Enteric Dysfunction (EED), a syndrome characterized by chronic gut inflammation, contributes towards stunting and poor response to enteric vaccines in children in developing countries. In this study, we evaluated major putative biomarkers of EED using growth faltering as its clinical proxy. Newborns (n = 380) were enrolled and followed till 18 months with monthly anthropometry. Biomarkers associated with gut and systemic inflammation were assessed at 6 and 9 months. Linear mixed effects model was used to determine the associations of these biomarkers with growth faltering between birth and 18 months. Fecal myeloperoxidase (neutrophil activation marker) at 6 months [beta = -0.207, p = 0.005], and serum GLP 2 (enterocyte proliferation marker) at 6 and 9 months [6M: beta = -0.271, p = 0.035; 9M: beta = -0.267, p = 0.045] were associated with decreasing LAZ score. Ferritin at 6 and 9 months was associated with decreasing LAZ score [6M: beta = -0.882, p < 0.0001; 9M: beta = -0.714, p < 0.0001] and so was CRP [beta = -0.451, p = 0.039] and AGP [beta = -0.443, p = 0.012] at 9 months. Both gut specific and systemic biomarkers correlated negatively with IGF 1, but only weakly correlated, if at all with each other. We therefore conclude that EED may be contributing directly towards growth faltering, and this pathway is not entirely through the pathway of systemic inflammation.

AB - The macro- and micro-structures of mineralised tissues hierarchy are well described and understood. However, investigation of their nanostructure is limited due to the intrinsic complexity of biological systems. Preceding transmission electron microscopy studies investigating mineralising tissues have not resolved fully the initial stages of mineral nucleation and growth within the collagen fibrils. In this study, analytical scanning transmission electron microscopy and electron energy-loss spectroscopy were employed to characterise the morphology, crystallinity and chemistry of the mineral at different stages of mineralization using a turkey tendon model. In the poorly mineralised regions, calcium ions associated with the collagen fibrils and ellipsoidal granules and larger clusters composed of amorphous calcium phosphate were detected. In the fully mineralised regions, the mineral had transformed into crystalline apatite with a plate-like morphology. A change in the nitrogen K-edge was observed and related to modifications of the functional groups associated with the mineralisation process. This transformation seen in the nitrogen K-edge might be an important step in maturation and mineralisation of collagen and lend fundamental insight into how tendon mineralises.

AB - Exposure to noise and ototoxic drugs are responsible for much of the debilitating hearing loss experienced by about 350 million people worldwide. Beyond hearing aids and cochlear implants, there have been no other FDA approved drug interventions established in the clinic that would either protect or reverse the effects of hearing loss. Using Auditory Brainstem Responses (ABR) in a guinea pig model, we demonstrate that fluvastatin, an inhibitor of HMG-CoA reductase, the rate-limiting enzyme of the mevalonate pathway, protects against loss of cochlear function initiated by high intensity noise. A novel synchrotron radiation based X ray tomographic method that imaged soft tissues at micrometer resolution in unsectioned cochleae, allowed an efficient, qualitative evaluation of the three dimensional internal structure of the intact organ. For quantitative measures, plastic embedded cochleae were sectioned followed by hair cell counting. Protection in noise-exposed cochleae is associated with retention of inner and outer hair cells. This study demonstrates the potential of HMG-CoA reductase inhibitors, already vetted in human medicine for other purposes, to protect against noise induced hearing loss.

AB - There are few instances in oncology where reciprocal clinical and laboratory translation studies have accelerated the understanding of disease biology and treatment more so than the decade following the Food and Drug Administration (FDA) approval of lenalidomide (RevlimidTM; Celgene Corporation, Summit, NJ, USA) for the treatment of patients with myelodysplastic syndrome (MDS) and chromosome 5q deletion (del(5q)). Lenalidomide was approved by the FDA in December 2005 on the merits of a multicenter phase 2 study, which demonstrated sustained and prolonged transfusion independence in the majority of participants. Since then, del(5q) MDS has emerged as one of the best characterized bone marrow malignancies and, in particular, has raised our understanding as to how allelic haplodeficiency underlies both its hematological phenotype and the selective sensitivity to lenalidomide by virtue of synthetic lethality. Herein, we review the clinical and biological discoveries that have advanced our understanding of del(5q) MDS and its treatment since its approval by United States and European regulatory agencies. PMID- 29445114 TI - Kinesin 1 regulates cilia length through an interaction with the Bardet-Biedl syndrome related protein CCDC28B. AB - Bardet-Biedl syndrome (BBS) is a ciliopathy characterized by retinal degeneration, obesity, polydactyly, renal disease and mental retardation. CCDC28B is a BBS-associated protein that we have previously shown plays a role in cilia length regulation whereby its depletion results in shortened cilia both in cells and Danio rerio (zebrafish). At least part of that role is achieved by its interaction with the mTORC2 component SIN1, but the mechanistic details of this interaction and/or additional functions that CCDC28B might play in the context of cilia remain poorly understood. Here we uncover a novel interaction between CCDC28B and the kinesin 1 molecular motor that is relevant to cilia. CCDC28B interacts with kinesin light chain 1 (KLC1) and the heavy chain KIF5B. Notably, depletion of these kinesin 1 components results in abnormally elongated cilia. Furthermore, through genetic interaction studies we demonstrate that kinesin 1 regulates ciliogenesis through CCDC28B. We show that kinesin 1 regulates the subcellular distribution of CCDC28B, unexpectedly, inhibiting its nuclear accumulation, and a ccdc28b mutant missing a nuclear localization motif fails to rescue the phenotype in zebrafish morphant embryos. Therefore, we uncover a previously unknown role of kinesin 1 in cilia length regulation that relies on the BBS related protein CCDC28B. PMID- 29445115 TI - The thick and thin of the central corneal thickness in glaucoma. AB - Central corneal thickness (CCT) is an important parameter in the assessment of any potential glaucoma patient. While it affects prognosis in ocular hypertension, its value in patients diagnosed with glaucoma is less certain. There are several biological factors and genetic components that may influence glaucoma progression, which have been associated with thinner CCT. The CCT itself can be affected by several factors including ethnicity, age, sex, glaucoma medications, genetics, and the subtype of glaucoma. Besides, there is variability in the measurement of CCT between difference types of devices. These factors need to be considered in the evaluation of glaucoma patients' CCT and its effect on interpretation of intraocular pressure levels and risk stratification. PMID- 29445116 TI - Evaluation of 3D heads-up vitrectomy: outcomes of psychometric skills testing and surgeon satisfaction. AB - OBJECTIVES: To evaluate the use of a three-dimensional heads-up microscope (3DM) during 25-gauge pars plana vitrectomy (PPV) compared with a traditional ophthalmic microscope (TM) in terms of efficacy, safety, and teaching and learning satisfaction. METHODS: Prospective comparative interventional study. Fifty eyes affected by one of the following diseases: rhegmatogenous or tractional retinal detachment, epiretinal membrane, full-thickness macular hole, vitreous hemorrhage, or dropped lens. The 50 eyes were randomly assigned to one of two groups: group A (25 eyes) underwent 25-gauge PPV with 3DM, and group B (25 eyes) underwent 25-gauge PPV with TM. The main outcome measures were the duration of the operation, intraoperative complications, and surgeon and observer satisfaction. A questionnaire was used to assess surgeon satisfaction according to the following parameters: comfort, visibility, image quality, depth perception, simplicity of use, maneuverability, and teaching. A questionnaire to assess observer satisfaction was completed by 20 observers (surgical residents or ophthalmic surgeons). RESULTS: The degree of satisfaction was higher using 3DM for both surgeons and observers (P < 0.001). The average duration of the operation did not differ significantly between the two methods. No major complications occurred for either method. CONCLUSIONS: PPV with 3DM is more comfortable for the surgeon and poses no substantially greater risk of complications for the patient. The high-definition screen delivers excellent depth perception and better screen parameter control, which results in high quality surgical performance. 3DM surgery helps to significantly improve teaching and learning intra-operative surgical procedures. PMID- 29445117 TI - Transitional correlation between inner-membrane potential and ATP levels of neuronal mitochondria. AB - The importance of highly active mitochondria and their contribution to neuronal function has been of recent interest. In most cases, however, mitochondrial activity is estimated using measurements of mitochondrial inner membrane potential (IMPmito), and little is known about the dynamics of native mitochondrial ATP (ATPmito). This study conducted simultaneous imaging of IMPmito and ATPmito in neurons to explore their behaviour and their correlation during physiological mitochondrial/neuronal activity. We found that mitochondrial size, transport velocity and transport direction are not dependent on ATPmito or IMPmito. However, changes in ATPmito and IMPmito during mitochondrial fission/fusion were found; IMPmito depolarized via mitochondrial fission and hyperpolarized via fusion, and ATPmito levels increased after fusion. Because the density of mitochondria is higher in growth cones (GCs) than in axonal processes, integrated ATPmito signals (density * ATPmito) were higher in GCs. This integrated signal in GCs correlated with axonal elongation. However, while the averaged IMPmito was relatively hyperpolarized in GCs, there was no correlation between IMPmito in GCs and axonal elongation. A detailed time-course analysis performed to clarify the reason for these discrepancies showed that IMPmito and ATPmito levels did not always correlate accurately; rather, there were several correlation patterns that changed over time. PMID- 29445118 TI - N1-methylnicotinamide is a signalling molecule produced in skeletal muscle coordinating energy metabolism. AB - Obesity is a major health problem, and although caloric restriction and exercise are successful strategies to lose adipose tissue in obese individuals, a simultaneous decrease in skeletal muscle mass, negatively effects metabolism and muscle function. To deeper understand molecular events occurring in muscle during weight-loss, we measured the expressional change in human skeletal muscle following a combination of severe caloric restriction and exercise over 4 days in 15 Swedish men. Key metabolic genes were regulated after the intervention, indicating a shift from carbohydrate to fat metabolism. Nicotinamide N methyltransferase (NNMT) was the most consistently upregulated gene following the energy-deficit exercise. Circulating levels of N1-methylnicotinamide (MNA), the product of NNMT activity, were doubled after the intervention. The fasting-fed state was an important determinant of plasma MNA levels, peaking at ~18 h of fasting and being lowest ~3 h after a meal. In culture, MNA was secreted by isolated human myotubes and stimulated lipolysis directly, with no effect on glucagon or insulin secretion. We propose that MNA is a novel myokine that enhances the utilization of energy stores in response to low muscle energy availability. Future research should focus on applying MNA as a biomarker to identify individuals with metabolic disturbances at an early stage. PMID- 29445119 TI - Conservation of a pH-sensitive structure in the C-terminal region of spider silk extends across the entire silk gene family. AB - Spiders produce multiple silks with different physical properties that allow them to occupy a diverse range of ecological niches, including the underwater environment. Despite this functional diversity, past molecular analyses show a high degree of amino acid sequence similarity between C-terminal regions of silk genes that appear to be independent of the physical properties of the resulting silks; instead, this domain is crucial to the formation of silk fibers. Here, we present an analysis of the C-terminal domain of all known types of spider silk and include silk sequences from the spider Argyroneta aquatica, which spins the majority of its silk underwater. Our work indicates that spiders have retained a highly conserved mechanism of silk assembly, despite the extraordinary diversification of species, silk types and applications of silk over 350 million years. Sequence analysis of the silk C-terminal domain across the entire gene family shows the conservation of two uncommon amino acids that are implicated in the formation of a salt bridge, a functional bond essential to protein assembly. This conservation extends to the novel sequences isolated from A. aquatica. This finding is relevant to research regarding the artificial synthesis of spider silk, suggesting that synthesis of all silk types will be possible using a single process. PMID- 29445120 TI - Proximity of breeding and foraging areas affects foraging effort of a crepuscular, insectivorous bird. AB - When complementary resources are required for an optimal life cycle, most animals need to move between different habitats. However, the level of connectivity between resources can vary and, hence, influence individuals' behaviour. We show that landscape composition and configuration affect the connectivity between breeding (heathlands) and foraging habitats (extensively-grazed grasslands) of the European Nightjar (Caprimulgus europaeus), a crepuscular insectivorous bird. On a daily basis, nightjars connect breeding and foraging sites by rapidly crossing unsuitable habitats in order to exploit a higher prey biomass in foraging sites. However, low availability of foraging habitat near breeding sites and clustered landscapes greatly increase foraging distance. Birds occupying these sub-optimal breeding areas compensate for longer travels by increasing foraging duration, and their physiology shows increased stress levels. All findings suggest that landscape heterogeneity can affect population dynamics of nightjars. Therefore, we recommend an integrated management approach for this EU protected bird species. PMID- 29445121 TI - Tomato AUXIN RESPONSE FACTOR 5 regulates fruit set and development via the mediation of auxin and gibberellin signaling. AB - Auxin response factors (ARFs) encode transcriptional factors that function in the regulation of plant development processes. A tomato ARF gene, SlARF5, was observed to be expressed at high levels in emasculated ovaries but maintained low expression levels in pollinated ovaries. The amiRNA SlARF5 lines exhibited ovary growth and formed seedless fruits following emasculation. These parthenocarpic fruits developed fewer locular tissues, and the fruit size and weight were decreased in transgenic lines compared to those of wild-type fruits. Gene expression analysis demonstrated that several genes involved in the auxin signaling pathway were downregulated, whereas some genes involved in the gibberellin-signaling pathway were enhanced by the decreased SlARF5 mRNA levels in transgenic plants, indicating that SlARF5 may play an important role in regulating both the auxin- and gibberellin-signaling pathways during fruit set and development. PMID- 29445122 TI - Deep phenotyping of speech and language skills in individuals with 16p11.2 deletion. AB - Recurrent deletions of a ~600-kb region of 16p11.2 have been associated with a highly penetrant form of childhood apraxia of speech (CAS). Yet prior findings have been based on a small, potentially biased sample using retrospectively collected data. We examine the prevalence of CAS in a larger cohort of individuals with 16p11.2 deletion using a prospectively designed assessment battery. The broader speech and language phenotype associated with carrying this deletion was also examined. 55 participants with 16p11.2 deletion (47 children, 8 adults) underwent deep phenotyping to test for the presence of CAS and other speech and language diagnoses. Standardized tests of oral motor functioning, speech production, language, and non-verbal IQ were conducted. The majority of children (77%) and half of adults (50%) met criteria for CAS. Other speech outcomes were observed including articulation or phonological errors (i.e., phonetic and cognitive-linguistic errors, respectively), dysarthria (i.e., neuromuscular speech disorder), minimal verbal output, and even typical speech in some. Receptive and expressive language impairment was present in 73% and 70% of children, respectively. Co-occurring neurodevelopmental conditions (e.g., autism) and non-verbal IQ did not correlate with the presence of CAS. Findings indicate that CAS is highly prevalent in children with 16p11.2 deletion with symptoms persisting into adulthood for many. Yet CAS occurs in the context of a broader speech and language profile and other neurobehavioral deficits. Further research will elucidate specific genetic and neural pathways leading to speech and language deficits in individuals with 16p11.2 deletions, resulting in more targeted speech therapies addressing etiological pathways. PMID- 29445123 TI - Psychosocial risk predicts high readmission rates for hematopoietic cell transplant recipients. AB - Hematopoietic cell transplantation (HCT) is an intensive treatment resulting in disease control however subsequent psychosocial distress is common. Screening for psychosocial risk factors that contribute to morbidity is underutilized; moreover, the value in screening is uncertain. We performed a retrospective study of 395 HCT patients who were screened for psychosocial risk using the Transplant Evaluation Rating Scale (TERS). Patients were classified by psychosocial risk as no-risk (TERS = 26.5, 52%) vs. at-risk (TERS > 26.5, 48%), with at-risk patients stratified by cumulative deficits into mild risk (TERS = 27-35.5, 39%) and moderate risk (TERS > 35.5, 9%). At-risk patients were more likely to be readmitted within 90 days (mild risk HR = 1.62, p = 0.02; moderate risk HR = 2.50, p = 0.002). Prior psychiatric history (HR = 1.81, p = 0.002) and poor coping skills (HR = 1.64, p = 0.04) also influenced readmission. At-risk patients were more likely to be readmitted for infection (no-risk = 12% vs. at-risk = 25%, p = 0.002). Pre-HCT screening with the TERS did not predict survival or length of stay although at-risk patients are at a heighted risk of readmission. Implementing strategies to reduce readmission in higher risk patients is warranted. PMID- 29445124 TI - Efficacy of mucosal polyanhydride nanovaccine against respiratory syncytial virus infection in the neonatal calf. AB - Human respiratory syncytial virus (HRSV) is a leading cause of severe acute lower respiratory tract infection in infants and children worldwide. Bovine RSV (BRSV) is closely related to HRSV and a significant cause of morbidity in young cattle. BRSV infection in calves displays many similarities to RSV infection in humans, including similar age dependency and disease pathogenesis. Polyanhydride nanoparticle-based vaccines (i.e., nanovaccines) have shown promise as adjuvants and vaccine delivery vehicles due to their ability to promote enhanced immunogenicity through the route of administration, provide sustained antigen exposure, and induce both antibody- and cell-mediated immunity. Here, we developed a novel, mucosal nanovaccine that encapsulates the post-fusion F and G glycoproteins from BRSV into polyanhydride nanoparticles and determined the efficacy of the vaccine against RSV infection using a neonatal calf model. Calves receiving the BRSV-F/G nanovaccine exhibited reduced pathology in the lungs, reduced viral burden, and decreased virus shedding compared to unvaccinated control calves, which correlated with BRSV-specific immune responses in the respiratory tract and peripheral blood. Our results indicate that the BRSV-F/G nanovaccine is highly immunogenic and, with optimization, has the potential to significantly reduce the disease burden associated with RSV infection in both humans and animals. PMID- 29445125 TI - Pin1 impairs microRNA biogenesis by mediating conformation change of XPO5 in hepatocellular carcinoma. AB - MicroRNA (miRNA) dysregulation is associated with the tumorigenesis and development of numerous human cancers. The defect in miRNA biogenesis is the main cause of miRNA dysregulation. We previously demonstrated that ERK-induced phosphorylation of XPO5 followed by peptidyl-prolyl cis/trans isomerase Pin1 mediated isomerization downregulates miRNA expression and contributes to hepatocellular carcinoma (HCC) development. However, how Pin1 precisely regulates miRNA biogenesis in HCC remains elusive. Here we reveal that Pin1 has a pivotal role in the miRNA maturation process by modulating phosphorylated Serine-Proline (pS-P) motif of XPO5 in a phosphorylation-dependent manner. By recognizing and binding to XPO5 via its WW domain, Pin1 catalyzes the conformation change of XPO5 and diminishes XPO5 ability to export pre-miRNAs from the nucleus to the cytoplasm, resulting in the reduced mature miRNA levels and promoted HCC development. Furthermore, downregulation of Pin1 by shRNA restores XPO5-dependent pre-miRNA export and effective biogenesis of mature miRNAs, leading to both in vitro and in vivo HCC inhibition. Therefore, our research discloses a new posttranscriptional regulatory mechanism of miRNA biosynthesis and provides the experimental basis for a novel HCC therapy by targeting Pin1. PMID- 29445126 TI - EGFR controls bone development by negatively regulating mTOR-signaling during osteoblast differentiation. AB - Mice deficient in epidermal growth factor receptor (Egfr-/- mice) are growth retarded and exhibit severe bone defects that are poorly understood. Here we show that EGFR-deficient mice are osteopenic and display impaired endochondral and intramembranous ossification resulting in irregular mineralization of their bones. This phenotype is recapitulated in mice lacking EGFR exclusively in osteoblasts, but not in mice lacking EGFR in osteoclasts indicating that osteoblasts are responsible for the bone phenotype. Experiments are presented demonstrating that signaling via EGFR stimulates osteoblast proliferation and inhibits their differentiation by suppression of the IGF-1R/mTOR-pathway via ERK1/2-dependent up-regulation of IGFBP-3. Osteoblasts from Egfr-/- mice show increased levels of IGF-1R and hyperactivation of mTOR-pathway proteins, including enhanced phosphorylation of 4E-BP1 and S6. The same changes are also seen in Egfr-/- bones. Importantly, pharmacological inhibition of mTOR with rapamycin decreases osteoblasts differentiation as well as rescues the low bone mass phenotype of Egfr-/- fetuses. Our results demonstrate that suppression of the IGF-1R/mTOR-pathway by EGFR/ERK/IGFBP-3 signaling is necessary for balanced osteoblast maturation providing a mechanism for the skeletal phenotype observed in EGFR-deficient mice. PMID- 29445127 TI - Cripto-1 contributes to stemness in hepatocellular carcinoma by stabilizing Dishevelled-3 and activating Wnt/beta-catenin pathway. AB - Identification and characterization of functional molecular targets conferring stemness properties in hepatocellular carcinoma (HCC) offers crucial insights to overcome the major hurdles of tumor recurrence, metastasis and chemoresistance in clinical management. In the current study, we investigated the significance of Cripto-1 in contributing to HCC stemness. Cripto-1 was upregulated in the sorafenib-resistant clones derived from HCC cell lines and patient-derived xenograft that we previously developed, suggesting an association between Cripto 1 and stemness. By in vitro experiments, Cripto-1 fostered cell proliferation, migration, and invasion. It also enhanced self-renewal ability and conferred chemoresistance of HCC cells. Consistently, silencing of Cripto-1 suppressed in vivo tumorigenicity on serial transplantation. On the downstream signaling mechanism, expression of major components of Wnt/beta-catenin pathway beta catenin, AXIN2, and C-MYC, accompanied by beta-catenin activity was reduced upon Cripto-1 knockdown. The suppressive effects on stemness properties with Cripto-1 knockdown in vitro and in vivo were partially rescued by forced expression of constitutively active beta-catenin. Further elucidation revealed the binding of Cripto-1 to Frizzled-7 (FZD7), low-density lipoprotein receptor-related protein 6 (LRP6) and Dishevelled-3 (DVL3) of the Wnt/beta-catenin pathway and stabilized DVL3 protein. Analyses with clinical samples validated Cripto-1 overexpression in HCC tissues, as well as a positive correlation between Cripto-1 and AXIN2 expressions. High Cripto-1 level in tumor was associated with poorer disease-free survival of HCC patients. Taken together, Cripto-1 binds to FZD7/LRP6 and DVL3, stabilizes DVL3 expression and activates the Wnt/beta-catenin signaling cascade to confer stemness in HCC. Our study findings substantiated the role of Cripto-1 in determining stemness phenotypes of HCC and mechanistically in modulating the Wnt/beta-catenin signaling cascade, one of the most frequently deregulated pathways in liver cancer. PMID- 29445128 TI - The brace helices of MLKL mediate interdomain communication and oligomerisation to regulate cell death by necroptosis. AB - The programmed cell death pathway, necroptosis, relies on the pseudokinase, Mixed Lineage Kinase domain-Like (MLKL), for cellular execution downstream of death receptor or Toll-like receptor ligation. Receptor-interacting protein kinase-3 (RIPK3)-mediated phosphorylation of MLKL's pseudokinase domain leads to MLKL switching from an inert to activated state, where exposure of the N-terminal four helix bundle (4HB) 'executioner' domain leads to cell death. The precise molecular details of MLKL activation, including the stoichiometry of oligomer assemblies, mechanisms of membrane translocation and permeabilisation, remain a matter of debate. Here, we dissect the function of the two 'brace' helices that connect the 4HB to the pseudokinase domain of MLKL. In addition to establishing that the integrity of the second brace helix is crucial for the assembly of mouse MLKL homotrimers and cell death, we implicate the brace helices as a device to communicate pseudokinase domain phosphorylation event(s) to the N-terminal executioner 4HB domain. Using mouse:human MLKL chimeras, we defined the first brace helix and adjacent loop as key elements of the molecular switch mechanism that relay pseudokinase domain phosphorylation to the activation of the 4HB domain killing activity. In addition, our chimera data revealed the importance of the pseudokinase domain in conferring host specificity on MLKL killing function, where fusion of the mouse pseudokinase domain converted the human 4HB + brace from inactive to a constitutive killer of mouse fibroblasts. These findings illustrate that the brace helices play an active role in MLKL regulation, rather than simply acting as a tether between the 4HB and pseudokinase domains. PMID- 29445129 TI - Light and temperature control the seasonal distribution of thaumarchaeota in the South Atlantic bight. AB - Mid-summer peaks in the abundance of Thaumarchaeota and nitrite concentration observed on the Georgia, USA, coast could result from in situ activity or advection of populations from another source. We collected data on the distribution of Thaumarchaeota, ammonia-oxidizing betaproteobacteria (AOB), Nitrospina, environmental variables and rates of ammonia oxidation during six cruises in the South Atlantic Bight (SAB) from April to November 2014. These data were used to examine seasonality of nitrification in offshore waters and to test the hypothesis that the bloom was localized to inshore waters. The abundance of Thaumarchaeota marker genes (16S rRNA and amoA) increased at inshore and nearshore stations starting in July and peaked in August at >107 copies L-1. The bloom did not extend onto the mid-shelf, where Thaumarchaeota genes ranged from 103 to 105 copies L-1. Ammonia oxidation rates (AO) were highest at inshore stations during summer (to 840 nmol L-1 d-1) and were always at the limit of detection at mid-shelf stations. Nitrite concentrations were correlated with AO (R = 0.94) and were never elevated at mid-shelf stations. Gene sequences from samples collected at mid-shelf stations generated using Archaea 16S rRNA primers were dominated by Euryarchaeota; sequences from inshore and nearshore stations were dominated by Thaumarchaeota. Thaumarchaeota were also abundant at depth at the shelf-break; however, this population was phylogenetically distinct from the inshore/nearshore population. Our analysis shows that the bloom is confined to inshore waters during summer and suggests that Thaumarchaeota distributions in the SAB are controlled primarily by photoinhibition and secondarily by water temperature. PMID- 29445130 TI - Comparative genomic inference suggests mixotrophic lifestyle for Thorarchaeota. AB - Thorarchaeota are a new archaeal phylum within the Asgard superphylum, whose ancestors have been proposed to play possible ecological roles in cellular evolution. However, little is known about the lifestyles of these uncultured archaea. To provide a better resolution of the ecological roles and metabolic capacity of Thorarchaeota, we obtained Thorarchaeota genomes reconstructed from metagenomes of different depth layers in mangrove and mudflat sediments. These genomes from deep anoxic layers suggest the presence of Thorarchaeota with the potential to degrade organic matter, fix inorganic carbon, reduce sulfur/sulfate and produce acetate. In particular, Thorarchaeota may be involved in ethanol production, nitrogen fixation, nitrite reduction, and arsenic detoxification. Interestingly, these Thorarchaeotal genomes are inferred to contain the tetrahydromethanopterin and tetrahydrofolate Wood-Ljungdahl (WL) pathways for CO2 reduction, and the latter WL pathway appears to have originated from bacteria. These archaea are predicted to be able to use various inorganic and organic carbon sources, possessing genes inferred to encode ribulose bisphosphate carboxylase-like proteins (normally without RuBisCO activity) and a near-complete Calvin-Benson-Bassham cycle. The existence of eukaryotic selenocysteine insertion sequences and many genes for proteins previously considered eukaryote-specific in Thorarchaeota genomes provide new insights into their evolutionary roles in the origin of eukaryotic cellular complexity. Resolving the metabolic capacities of these enigmatic archaea and their origins will enhance our understanding of the origins of eukaryotes and their roles in ecosystems. PMID- 29445131 TI - Strains of the toxic and bloom-forming Nodularia spumigena (cyanobacteria) can degrade methylphosphonate and release methane. AB - Nodularia spumigena is a nitrogen-fixing cyanobacterium that forms toxic blooms in the Baltic Sea each summer and the availability of phosphorous is an important factor limiting the formation of these blooms. Bioinformatic analysis identified a phosphonate degrading (phn) gene cluster in the genome of N. spumigena suggesting that this bacterium may use phosphonates as a phosphorus source. Our results show that strains of N. spumigena could grow in medium containing methylphosphonic acid (MPn) as the sole source of phosphorous and released methane when growing in medium containing MPn. We analyzed the total transcriptomes of N. spumigena UHCC 0039 grown using MPn and compared them with cultures growing in Pi-replete medium. The phnJ, phosphonate lyase gene, was upregulated when MPn was the sole source of phosphorus, suggesting that the expression of this gene could be used to indicate the presence of bioavailable phosphonates. Otherwise, growth on MPn resulted in only a minor reconstruction of the transcriptome and enabled good growth. However, N. spumigena strains were not able to utilize any of the anthropogenic phosphonates tested. The phosphonate utilizing pathway may offer N. spumigena a competitive advantage in the Pi limited cyanobacterial blooms of the Baltic Sea. PMID- 29445132 TI - Microbiome assembly of avian eggshells and their potential as transgenerational carriers of maternal microbiota. AB - The microbiome is essential for development, health and homeostasis throughout an animal's life. Yet, the origins and transmission processes governing animal microbiomes remain elusive for non-human vertebrates, oviparous vertebrates in particular. Eggs may function as transgenerational carriers of the maternal microbiome, warranting characterisation of egg microbiome assembly. Here, we investigated maternal and environmental contributions to avian eggshell microbiota in wild passerine birds: woodlark Lullula arborea and skylark Alauda arvensis. Using 16S rRNA gene sequencing, we demonstrated in both lark species, at the population and within-nest levels, that bacterial communities of freshly laid eggs were distinct from the female cloacal microbiome. Instead, soil-borne bacteria appeared to thrive on freshly laid eggs, and eggshell microbiota composition strongly resembled maternal skin, body feather and nest material communities, sources in direct contact with laid eggs. Finally, phylogenetic structure analysis and microbial source tracking underscored species sorting from directly contacting sources rather than in vivo-transferred symbionts. The female egg-nest system allowed an integrative assessment of avian egg microbiome assembly, revealing mixed modes of symbiont acquisition not previously documented for vertebrate eggs. Our findings illuminated egg microbiome origins, which suggested a limited potential of eggshells for transgenerational transmission, encouraging further investigation of eggshell microbiome functions in vertebrates. PMID- 29445133 TI - Photoautotrophic organisms control microbial abundance, diversity, and physiology in different types of biological soil crusts. AB - Biological soil crusts (biocrusts) cover about 12% of the Earth's land masses, thereby providing ecosystem services and affecting biogeochemical fluxes on a global scale. They comprise photoautotrophic cyanobacteria, algae, lichens and mosses, which grow together with heterotrophic microorganisms, forming a model system to study facilitative interactions and assembly principles in natural communities. Biocrusts can be classified into cyanobacteria-, lichen-, and bryophyte-dominated types, which reflect stages of ecological succession. In this study, we examined whether these categories include a shift in heterotrophic communities and whether this may be linked to altered physiological properties. We analyzed the microbial community composition by means of qPCR and high throughput amplicon sequencing and utilized flux measurements to investigate their physiological properties. Our results revealed that once 16S and 18S rRNA gene copy numbers increase, fungi become more predominant and alpha diversity increases with progressing succession. Bacterial communities differed significantly between biocrust types with a shift from more generalized to specialized organisms along succession. CO2 gas exchange measurements revealed large respiration rates of late successional crusts being significantly higher than those of initial biocrusts, and different successional stages showed distinct NO and HONO emission patterns. Thus, our study suggests that the photoautotrophic organisms facilitate specific microbial communities, which themselves strongly influence the overall physiological properties of biocrusts and hence local to global nutrient cycles. PMID- 29445134 TI - The long non-coding RNA FOXD2-AS1 promotes bladder cancer progression and recurrence through a positive feedback loop with Akt and E2F1. AB - Long non-coding RNAs (lncRNAs) have been identified as significant regulators in cancer progression. Positive feedback loops between lncRNAs and transcription factors have attracted increasing attention. Akt pathway plays a crucial role in bladder cancer growth and recurrence. In the present study, we demonstrate a novel regulatory pattern involving FOXD2-AS1, Akt, and E2F1. FOXD2-AS1 is highly expressed in bladder cancer and is associated with tumor stage, recurrence, and poor prognosis. Further experiments showed that FOXD2-AS1 promotes bladder cancer cell proliferation, migration, and invasion in vitro and in vivo. Microarray analysis demonstrated that FOXD2-AS1 negatively regulates the expression of Tribbles pseudokinase 3 (TRIB3), a negative regulator of Akt. Mechanistically, FOXD2-AS1 forms an RNA-DNA complex with the promoter of TRIB3, the transcriptional activity of which is subsequently repressed, and leads to the activation of Akt, which further increases the expression of E2F1, a vital transcription factor involved in the G/S transition. Interestingly, E2F1 could bind to the FOXD2-AS1 promoter region and subsequently enhance its transcriptional activity, indicating that FOXD2-AS1/Akt/E2F1 forms a feedback loop. In summary, this regulatory pattern of positive feedback may be a novel target for the treatment of bladder cancer and FOXD2-AS1 has the potential to be a new recurrence predictor.

AB - The purpose of this study is to determine neural, vascular, protein secretion, and cellular signaling changes with disease progression in lacrimal glands of the thrombospondin-1-/- (TSP-1-/-) mouse model of dry eye compared to C57BL/6 wild type (WT) mice. Neural innervation was reduced in TSP-1-/- lacrimal glands compared to WT controls, whereas the number of blood vessels was increased. Intracellular Ca2+ stores and the amount of lysosomes, mitochondria, and secretory granules, but not the endoplasmic reticulum, were reduced in TSP-1-/- compared to WT acini at 12 weeks of age. Ex vivo high KCl-evoked secretion was decreased in TSP-1-/- compared to WT lacrimal gland tissue pieces. The alpha1D adrenergic agonist-stimulated response was increased in TSP-1-/- at 4 and 24 weeks but decreased at 12 weeks, and the ATP and MeSATP-stimulated peak [Ca2+]i responses were decreased at 24 weeks. These changes were observed prior to the appearance of mononuclear infiltrates. We conclude that in the lacrimal gland the absence of TSP-1: injures peripheral nerves; blocks efferent nerve activation; decreases protein secretion; and alters intracellular Ca2+ stores. Through these effects the absence of TSP-1 leads to disruption of ocular surface homeostasis and development of dry eye.

AB - Dietary antigen acquisition by lamina propria (LP) dendritic cells (DCs) is crucial to induce oral tolerance and maintain homeostasis. However, encountering innocuous antigens during infection can lead to inflammatory responses, suggesting processes may limit steady-state luminal antigen capture during infection. We observed that goblet cell (GC) associated antigen passages (GAPs), a steady-state pathway delivering luminal antigens to LP-DCs, are inhibited during Salmonella infection. GAP inhibition was mediated by IL-1beta. Infection abrogated luminal antigen delivery and antigen-specific T cell proliferation in the mesenteric lymph node (MLN). Antigen-specific T cell proliferation to dietary antigen was restored by overriding GAP suppression; however, this did not restore regulatory T cell induction, but induced inflammatory T cell responses. Salmonella translocation to the MLN required GCs and correlated with GAPs. Genetic manipulations overriding GAP suppression, or antibiotics inducing colonic GAPs, but not antibiotics that do not, increased dissemination and worsened outcomes independent of luminal pathogen burden. Thus, steady-state sampling pathways are suppressed during infection to prevent responses to dietary antigens, limit pathogen entry, and lessen the disease. Moreover, antibiotics may worsen Salmonella infection by means beyond blunting gut microbiota colonization resistance, providing new insight into how precedent antibiotic use aggravates enteric infection. PMID- 29445137 TI - Metabolic features of cancer stem cells: the emerging role of lipid metabolism. AB - Cancer stem cells (CSCs) are an uncommon subset of tumor cells capable of self renewal, differentiating, and recreating the parental tumor when transplanted into the murine background. Over the past two decades, efforts toward understanding CSC biology culminated into identifying a set of signaling pathways sustaining "stemness". Nevertheless, while metabolic rewiring is nowadays considered a hallmark of cancer, no consensus has been reached on the metabolic features underlying the plastic nature of CSCs, which are capable of residing in a dormant state, and able to rapidly proliferate when the need to repopulate the tumor mass arises. An emerging concept in the field of CSC metabolism is that these cells are extremely reliant on the activity of enzymes involved in lipid metabolism, such as stearoyl-CoA desaturase 1 (SCD1) and 3-hydroxy-3 methylglutharyl-coenzyme A reductase (HMG-CoAR). Indeed, SCD1 and HMG-CoAR have been described as key factors for the correct function of a number of concatenated pathways involved in CSC fate decision, such as Hippo and Wnt. In the present review, we describe metabolic futures of CSCs with a special focus on lipid metabolism, which until now represents an underappreciated force in maintaining CSCs and an attractive therapeutic target. PMID- 29445138 TI - Non-toxic engineered carbon nanodiamond concentrations induce oxidative/nitrosative stress, imbalance of energy metabolism, and mitochondrial dysfunction in microglial and alveolar basal epithelial cells. AB - Engineered nanoparticles are finding a wide spectrum of biomedical applications, including drug delivery and capacity to trigger cytotoxic phenomena, potentially useful against tumor cells. The full understanding of their biosafety and interactions with cell processes is mandatory. Using microglial (BV-2) and alveolar basal epithelial (A549) cells, in this study we determined the effects of engineered carbon nanodiamonds (ECNs) on cell viability, nitric oxide (NO) and reactive oxygen species (ROS) production, as well as on energy metabolism. Particularly, we initially measured decrease in cell viability as a function of increasing ECNs doses, finding similar cytotoxic ECN effects in the two cell lines. Subsequently, using apparently non-cytotoxic ECN concentrations (2 ug/mL causing decrease in cell number < 5%) we determined NO and ROS production, and measured the concentrations of compounds related to energy metabolism, mitochondrial functions, oxido-reductive reactions, and antioxidant defences. We found that in both cell lines non-cytotoxic ECN concentrations increased NO and ROS production with sustained oxidative/nitrosative stress, and caused energy metabolism imbalance (decrease in high energy phosphates and nicotinic coenzymes) and mitochondrial malfunctioning (decrease in ATP/ADP ratio).These results underline the importance to deeply investigate the molecular and biochemical changes occurring upon the interaction of ECNs (and nanoparticles in general) with living cells, even at apparently non-toxic concentration. Since the use of ECNs in biomedical field is attracting increasing attention the complete evaluation of their biosafety, toxicity and/or possible side effects both in vitro and in vivo is mandatory before these highly promising tools might find the correct application.

PMID- 29445139 TI - Dynamic network biomarker indicates pulmonary metastasis at the tipping point of hepatocellular carcinoma. AB - Developing predictive biomarkers that can detect the tipping point before metastasis of hepatocellular carcinoma (HCC), is critical to prevent further irreversible deterioration. To discover such early-warning signals or biomarkers of pulmonary metastasis in HCC, we analyse time-series gene expression data in spontaneous pulmonary metastasis mice HCCLM3-RFP model with our dynamic network biomarker (DNB) method, and identify CALML3 as a core DNB member. All experimental results of gain-of-function and loss-of-function studies show that CALML3 could indicate metastasis initiation and act as a suppressor of metastasis. We also reveal the biological role of CALML3 in metastasis initiation at a network level, including proximal regulation and cascading influences in dysfunctional pathways. Our further experiments and clinical samples show that DNB with CALML3 reduced pulmonary metastasis in liver cancer. Actually, loss of CALML3 predicts shorter overall and relapse-free survival in postoperative HCC patients, thus providing a prognostic biomarker and therapy target in HCC. PMID- 29445141 TI - Continuous depth profile of the rock strength in the Nankai accretionary prism based on drilling performance parameters. AB - A new method for evaluating the in situ rock strength beneath the seafloor is proposed and applied to the Nankai Trough accretionary prism. The depth continuous in situ rock strength is a critical parameter for numerous studies in earth science, particularly for seismology and tectonics at plate convergence zones; yet, measurements are limited owing to a lack of drilled cores. Here, we propose a new indicator of strength, the equivalent strength (EST), which is determined only by drilling performance parameters such as drill string rotational torque, bit depth, and string rotational speed. A continuous depth profile of EST was drawn from 0 to 3000 m below the seafloor (mbsf) across the forearc basin and accretionary prism in the Nankai Trough. The EST did not show a significant increase around the forearc basin-accretionary prism boundary, but it did show a clear increase within the prism, ca. below 1500 mbsf. This result may indicate that even the shallow accretionary prism has been strengthened by horizontal compression derived from plate subduction. The EST is a potential parameter to continuously evaluate the in situ rock strength during drilling, and its accuracy of the absolute value can be improved by combining with laboratory drilling experiments.

AB - Despite the increasing understanding of the magnitude and drivers of carbon gas emissions from inland waters, the relevance of water fluctuation and associated drying on their dynamics is rarely addressed. Here, we quantified CO2 and CH4 fluxes from a set of temporary ponds across seasons. The ponds were in all occasion net CO2 emitters irrespective of the presence or absence of water. While the CO2 fluxes were in the upper range of emissions for freshwater lentic systems, CH4 fluxes were mostly undetectable. Dry habitats substantially contributed to these emissions and were always a source of CO2, whereas inundated habitats acted either as a source or a sink of atmospheric CO2 along the year. Higher concentrations of coloured and humic organic matter in water and sediment were linked to higher CO2 emissions. Composition of the sediment microbial community was related both to dissolved organic matter concentration and composition, but we did not find a direct link with CO2 fluxes. The presence of methanogenic archaea in most ponds suggested the potential for episodic CH4 production and emission. Our results highlight the need for spatially and temporally inclusive approaches that consider the dry phases and habitats to characterize carbon cycling in temporary systems. PMID- 29445144 TI - Lenalidomide regulates CNS autoimmunity by promoting M2 macrophages polarization. AB - Multiple sclerosis (MS) is a chronic and debilitating neurological disorder of the central nervous system (CNS), characterized by infiltration of leukocytes into CNS and subsequent demyelination. Emerging evidences have revealed the beneficial roles of M2 macrophages in ameliorating experimental autoimmune encephalomyelitis (EAE), a model for MS. Here, we identify that lenalidomide alone could promote macrophages M2 polarization to prevent the progression of EAE, which is associated with subsequent inhibition of proinflammatory Th1 and Th17 cells both in peripheral lymph system and CNS. Depletion of macrophages by pharmacology treatment of clodronate liposomes or transferring lenalidomide induced BMDMs in EAE mice completely abolished the therapeutic effect of lenalidomide or prevented EAE development, respectively. The macrophages-derived IL10 was upregulated both in vivo and in vitro after lenalidomide treatment. Moreover, lenalidomide-treated IL10-dificient EAE mice had higher clinical scores and more severe CNS damage, and intravenous injection of lenalidomide-treated IL10-/- BMDMs into mice with EAE at disease onset did not reverse disease severity, implying IL10 may be essential in lenalidomide-ameliorated EAE. Mechanistically, lenalidomide significantly increased expression and autocrine secretion of IL10, subsequently activated STAT3-mediated expression of Ym1. These studies facilitate the development of potential novel therapeutic application of lenalidomide for the treatment of MS. PMID- 29445145 TI - Canagliflozin mediated dual inhibition of mitochondrial glutamate dehydrogenase and complex I: an off-target adverse effect. AB - Recent FDA Drug Safety Communications report an increased risk for acute kidney injury in patients treated with the gliflozin class of sodium/glucose co transport inhibitors indicated for treatment of type 2 diabetes mellitus. To identify a potential rationale for the latter, we used an in vitro human renal proximal tubule epithelial cell model system (RPTEC/TERT1), physiologically representing human renal proximal tubule function. A targeted metabolomics approach, contrasting gliflozins to inhibitors of central carbon metabolism and mitochondrial function, revealed a double mode of action for canagliflozin, but not for its analogs dapagliflozin and empagliflozin. Canagliflozin inhibited the glutamate dehydrogenase (GDH) and mitochondrial electron transport chain (ETC) complex I at clinically relevant concentrations. This dual inhibition specifically prevented replenishment of tricarboxylic acid cycle metabolites by glutamine (anaplerosis) and thus altered amino acid pools by increasing compensatory transamination reactions. Consequently, canagliflozin caused a characteristic intracellular accumulation of glutamine, glutamate and alanine in confluent, quiescent RPTEC/TERT1. Canagliflozin, but none of the classical ETC inhibitors, induced cytotoxicity at particularly low concentrations in proliferating RPTEC/TERT1, serving as model for proximal tubule regeneration in situ. This finding is testimony of the strong dependence of proliferating cells on glutamine anaplerosis via GDH. Our discovery of canagliflozin-mediated simultaneous inhibition of GDH and ETC complex I in renal cells at clinically relevant concentrations, and their particular susceptibility to necrotic cell death during proliferation, provides a mechanistic rationale for the adverse effects observed especially in patients with preexisting chronic kidney disease or previous kidney injury characterized by sustained regenerative tubular epithelial cell proliferation. PMID- 29445146 TI - Dural effects of oxidative stress on cardiomyogenesis via Gata4 transcription and protein ubiquitination. AB - Oxidative stress generates reactive oxygen species (ROS) that can promote or inhibit cardiac differentiation of stem cells dependent on the intensity of stimuli as well as cellular context in redox and differentiation status. In the current study, we confirmed that suitable intensity of hydrogen peroxide at the formation stage of embryoid bodies (EBs) effectively favored the formation of spontaneously beating cardiomyocytes from P19 embryonal carcinoma cells. Mechanistic studies implicated that extrinsic ROS enhanced the Caspase-mediated degradation of Oct4 and Nanog, two factors that governing pluripotent property. Further experiments suggested that a cohort of Nanog together with histone deacetylase 4 (Hdac4) played a critical role in establishing and maintaining the silent transcriptional status of Gata4 and Nkx2.5 in undifferentiated cells. Thus, an impulse of hydrogen peroxide depleted Nanog and Hdac4 via a caspase dependent manner to ameliorate the repression on Gata4 and Nkx2.5 promoters, thereby generating a persistent activation on cardiac differentiation program. Meanwhile, we found that excessive ROS-activated JNK cascade to facilitate the ubiquitination and subsequent degradation of Gata4 protein. Overall, our results indicate that suitable ROS promotes the activation of Gata4 in transcription, while excessive ROS targets Gata4 protein for proteasome-dependent degradation. Gata4 is an important modulator balancing the promoting and inhibitory effects of oxidative stress on differentiation program of cardiomyogenesis. PMID- 29445147 TI - Long non-coding RNA PVT1 predicts poor prognosis and induces radioresistance by regulating DNA repair and cell apoptosis in nasopharyngeal carcinoma. AB - The long non-coding RNA, plasmacytoma variant translocation 1 (PVT1), is highly expressed in a variety of tumors, and is believed to be a potential oncogene. However, the role and mechanism of action of PVT1 in the carcinogenesis and progression of nasopharyngeal carcinomas (NPCs) remains unclear. In this study, for the first time, we have discovered that PVT1 shows higher expression in NPCs than in normal nasopharyngeal epithelial tissue, and patients with NPCs who show higher expression of PVT1 have worse progression-free and overall survivals. Additionally, we observed that the proliferation of NPC cells decreased, and their rate of apoptosis increased; these results indicated that the knockdown of PVT1 expression in the NPC cells induced radiosensitivity. Further, we have shown that the knockdown of PVT1 expression can induce apoptosis in the NPC cells by influencing the DNA damage repair pathway after radiotherapy. In general, our study shows that PVT1 may be a novel biomarker for prognosis and a new target for the treatment of NPCs. Additionally, targeting PVT1 may be a potential strategy for the clinical management of NPC and for the improvement of the curative effect of radiation in NPCs. PMID- 29445148 TI - Temporal requirements for ISL1 in sympathetic neuron proliferation, differentiation, and diversification. AB - Malformations of the sympathetic nervous system have been associated with cardiovascular instability, gastrointestinal dysfunction, and neuroblastoma. A better understanding of the factors regulating sympathetic nervous system development is critical to the development of potential therapies. Here, we have uncovered a temporal requirement for the LIM homeodomain transcription factor ISL1 during sympathetic nervous system development by the analysis of two mutant mouse lines: an Isl1 hypomorphic line and mice with Isl1 ablated in neural crest lineages. During early development, ISL1 is required for sympathetic neuronal fate determination, differentiation, and repression of glial differentiation, although it is dispensable for initial noradrenergic differentiation. ISL1 also plays an essential role in sympathetic neuron proliferation by controlling cell cycle gene expression. During later development, ISL1 is required for axon growth and sympathetic neuron diversification by maintaining noradrenergic differentiation, but repressing cholinergic differentiation. RNA-seq analyses of sympathetic ganglia from Isl1 mutant and control embryos, together with ISL1 ChIP seq analysis on sympathetic ganglia, demonstrated that ISL1 regulates directly or indirectly several distinct signaling pathways that orchestrate sympathetic neurogenesis. A number of genes implicated in neuroblastoma pathogenesis are direct downstream targets of ISL1. Our study revealed a temporal requirement for ISL1 in multiple aspects of sympathetic neuron development, and suggested Isl1 as a candidate gene for neuroblastoma. PMID- 29445149 TI - Let-7c inhibits cholangiocarcinoma growth but promotes tumor cell invasion and growth at extrahepatic sites. AB - Cholangiocarcinoma (CCA) is a cancer type with high postoperative relapse rates and poor long-term survival largely due to tumor invasion, distant metastasis, and multidrug resistance. Deregulated microRNAs (miRNAs) are implicated in several cancer types including CCA. The specific roles of the miRNA let-7c in cholangiocarcinoma are not known and need to be further elucidated. In our translational study we show that microRNA let-7c expression was significantly downregulated in human cholangiocarcinoma tissues when compared to adjacent tissues of the same patient. Let-7c inhibited the tumorigenic properties of cholangiocarcinoma cells including their self-renewal capacity and sphere formation in vitro and subcutaneous cancer cell growth in vivo. Ectopic let-7c overexpression suppressed migration and invasion capacities of cholangiocarcinoma cell lines in vitro, however, promoted distant invasiveness in vivo. Furthermore, we found that let-7c regulated the aforementioned malignant biological properties, at least in part, through regulation of EZH2 protein expression and through the DVL3/beta-catenin axis. The miRNA let-7c thus plays an important dual role in regulating tumorigenic and metastatic abilities of human cholangiocarcinoma through mechanisms involving EZH2 protein and the DVL3/beta catenin axis. PMID- 29445150 TI - Loss of NDRG2 in liver microenvironment inhibits cancer liver metastasis by regulating tumor associate macrophages polarization. AB - The liver is the predominant metastatic site for several types of malignancies. Tumor-associated macrophages (TAMs) in the liver play crucial roles in the metastasis process. Shifting tumor-promoting M2-like TAMs toward the M1-like phenotype, which exerts tumor suppressor functions via phagocytosis and the secretion of inhibitory factors, may be a potential therapeutic strategy for liver cancer metastasis treatment.We first cloned NDRG2 (N-myc downstream regulated gene 2) and verified its tumor suppressor role in multiple solid tumors, including colorectal cancer and hepatocellular carcinoma. However, its role in the tumor-associated liver microenvironment, especially in TAMs, has not been illustrated. By establishing a liver cancer metastasis model in wild-type (WT) and Ndrg2 knockout (Ndrg2-/-) mice, we found that the loss of the tumor suppressor Ndrg2 in liver microenvironment significantly suppressed the growth of liver colonies. In addition, this process was accompanied by a higher proportion of M1-like TAM infiltration in Ndrg2-/- mice. Interestingly, bone marrow (BM) transplantation revealed that BM-derived macrophages (BMDMs) rather than liver resident Kupffer cells were responsible for the inhibitory effect. We further demonstrated that loss of Ndrg2 influenced TAM polarization via the NF-kappaB pathway. Inhibition of IkappaBalpha phosphorylation in cancer cell-conditioned medium-stimulated BMDMs decreased M1 marker expression in Ndrg2-/- macrophages. Finally, in vitro, invasion, migration, and proliferation assays confirmed that NF-kappaB participated in the tumor suppressor function of Ndrg2-/- macrophages. Collectively, our findings highlight the role of NDRG2 in the regulation of TAM polarization and its function in promoting cancer liver metastasis. PMID- 29445151 TI - The vesicle trafficking regulator PN_SCD1 is demethylated and overexpressed in florets of apomictic Paspalum notatum genotypes. AB - Apomixis (asexual reproduction through seeds) is considered a deviation of the sexual reproductive pathway leading to the development of clonal progenies genetically identical to the mother plant. Here we used the Methylation-Sensitive Amplification Polymorphism (MSAP) technique to characterize cytosine methylation patterns occurring in florets of sexual and aposporous Paspalum notatum genotypes, in order to identify epigenetically-controlled genes putatively involved in apomixis development. From twelve polymorphic MSAP-derived sequences, one (PN_6.6, later renamed PN_SCD1) was selected due to its relevant annotation and differential representation in apomictic and sexual floral transcriptome libraries. PN_SCD1 encodes the DENN domain/WD repeat-containing protein SCD1, which interacts with RAB GTPases- and/or MAPKs to promote specialized cell division, functions in clathrin-mediated membrane transport and acts as potential substrate receptor of CUL4 E3 ubiquitin ligases. Quantitative RT-PCR and comparative RNAseq analyses of laser microdissected nucellar cells confirmed PN_SCD1 upregulation in florets of apomictic plants and revealed that overexpression takes place just before the onset of apospory initials. Moreover, we found that several SCD1 molecular partners are expressed in P. notatum florets and upregulated in apomictic plants. Our results disclosed a specific vesicle trafficking molecular pathway epigenetically modulated during apomixis. PMID- 29445152 TI - Fourier transform spectrometer on silicon with thermo-optic non-linearity and dispersion correction. AB - Miniaturized integrated spectrometers will have unprecedented impact on applications ranging from unmanned aerial vehicles to mobile phones, and silicon photonics promises to deliver compact, cost-effective devices. Mirroring its ubiquitous free-space counterpart, a silicon photonics-based Fourier transform spectrometer (Si-FTS) can bring broadband operation and fine resolution to the chip scale. Here we present the modeling and experimental demonstration of a thermally tuned Si-FTS accounting for dispersion, thermo-optic non-linearity, and thermal expansion. We show how these effects modify the relation between the spectrum and interferogram of a light source and we develop a quantitative correction procedure through calibration with a tunable laser. We retrieve a broadband spectrum (7 THz around 193.4 THz with 0.38-THz resolution consuming 2.5 W per heater) and demonstrate the Si-FTS resilience to fabrication variations-a major advantage for large-scale manufacturing. Providing design flexibility and robustness, the Si-FTS is poised to become a fundamental building block for on chip spectroscopy. PMID- 29445153 TI - Development of a chimeric Zika vaccine using a licensed live-attenuated flavivirus vaccine as backbone. AB - The global spread of Zika virus (ZIKV) and its unexpected association with congenital defects necessitates the rapid development of a safe and effective vaccine. Here we report the development and characterization of a recombinant chimeric ZIKV vaccine candidate (termed ChinZIKV) that expresses the prM-E proteins of ZIKV using the licensed Japanese encephalitis live-attenuated vaccine SA14-14-2 as the genetic backbone. ChinZIKV retains its replication activity and genetic stability in vitro, while exhibiting an attenuation phenotype in multiple animal models. Remarkably, immunization of mice and rhesus macaques with a single dose of ChinZIKV elicits robust and long-lasting immune responses, and confers complete protection against ZIKV challenge. Significantly, female mice immunized with ChinZIKV are protected against placental and fetal damage upon ZIKV challenge during pregnancy. Overall, our study provides an alternative vaccine platform in response to the ZIKV emergency, and the safety, immunogenicity, and protection profiles of ChinZIKV warrant further clinical development. PMID- 29445154 TI - Interleukin 4 modulates microglia homeostasis and attenuates the early slowly progressive phase of amyotrophic lateral sclerosis. AB - Microglia activation is a commonly pathological hallmark of neurodegenerative diseases, such as amyotrophic lateral sclerosis (ALS), a devastating disorder characterized by a selective motor neurons degeneration. Whether such activation might represent a causal event rather than a secondary epiphenomenon remains elusive. Here, we show that CNS-delivery of IL-4-via a lentiviral-mediated gene therapy strategy-skews microglia to proliferate, inducing these cells to adopt the phenotype of slowly proliferating cells. Transcriptome analysis revealed that IL-4-treated microglia express a broad number of genes normally encoded by embryonic microglia. Since embryonic microglia sustain CNS development, we then hypothesized that turning adult microglia to acquire such phenotype via IL-4 might be an efficient in vivo strategy to sustain motor neuron survival in ALS. IL-4 gene therapy in SOD1G93A mice resulted in a general amelioration of clinical outcomes during the early slowly progressive phase of the disease. However, such approach did not revert neurodegenerative processes occurring in the late and fast progressing phase of the disease. PMID- 29445155 TI - The cytotoxicity of coxsackievirus B3 is associated with a blockage of autophagic flux mediated by reduced syntaxin 17 expression. AB - Coxsackievirus B3 (CVB3) is an important human pathogen linked to cardiac arrhythmias and acute heart failure. CVB3 infection has been reported to induce the formation of autophagosomes that support the viral replication in host cells. Interestingly, our study shows that the accumulation of autophagosomes during CVB3 infection is caused by a blockage of autophagosome-lysosome fusion rather than the induction of autophagosome biogenesis. Moreover, CVB3 decreases the transcription and translation of syntaxin 17 (STX17), a SNARE (soluble N ethylmaleimide-sensitive factor activating protein receptor) protein involved in autophagosome-lysosome fusion. Overexpression of STX17 restored the autophagic flux, alleviated the virus-induced lysosomal dysfunction, and decreased the apoptosis induced by CVB3 infection in HeLa cells. Taken together, our results suggest that CVB3 infection impairs the autophagic flux by blocking autophagosome lysosome fusion. These findings thus point to potential new therapeutic strategies targeting STX17 or autophagosome-lysosome fusion for treating CVB3 associated diseases. PMID- 29445156 TI - Probing electrochemical reactions in organic cathode materials via in operando infrared spectroscopy. AB - Organic materials are receiving an increasing amount of attention as electrode materials for future post lithium-ion batteries due to their versatility and sustainability. However, their electrochemical reaction mechanism has seldom been investigated. This is a direct consequence of a lack of straightforward and broadly available analytical techniques. Herein, a straightforward in operando attenuated total reflectance infrared spectroscopy method is developed that allows visualization of changes of all infrared active bands that occur as a consequence of reduction/oxidation processes. In operando infrared spectroscopy is applied to the analysis of three different organic polymer materials in lithium batteries. Moreover, this in operando method is further extended to investigation of redox reaction mechanism of poly(anthraquinonyl sulfide) in a magnesium battery, where a reduction of carbonyl bond is demonstrated as a mechanism of electrochemical activity. Conclusions done by the in operando results are complemented by synthesis of model compound and density functional theory calculation of infrared spectra. PMID- 29445157 TI - Enhanced viral-mediated cochlear gene delivery in adult mice by combining canal fenestration with round window membrane inoculation. AB - Cochlear gene therapy holds promise for the treatment of genetic deafness. Assessing its impact in adult murine models of hearing loss, however, has been hampered by technical challenges that have made it difficult to establish a robust method to deliver transgenes to the mature murine inner ear. Here in we demonstrate the feasibility of a combined round window membrane injection and semi-circular canal fenestration technique in the adult cochlea. Injection of both AAV2/9 and AAV2/Anc80L65 via this approach in P15-16 and P56-60 mice permits robust eGFP transduction of virtually all inner hair cells throughout the cochlea with variable transduction of vestibular hair cells. Auditory thresholds are not compromised. Transduction rate and cell tropism is primarily influenced by viral titer and AAV serotype but not age at injection. This approach is safe, versatile and efficient. Its use will facilitate studies using cochlear gene therapy in murine models of hearing loss over a wide range of time points. PMID- 29445159 TI - Microfluidic cell sorting by stiffness to examine heterogenic responses of cancer cells to chemotherapy. AB - Cancers consist of a heterogeneous populations of cells that may respond differently to treatment through drug-resistant sub-populations. The scarcity of these resistant sub-populations makes it challenging to understand how to counter their resistance. We report a label-free microfluidic approach to separate cancer cells treated with chemotherapy into sub-populations enriched in chemoresistant and chemosensitive cells based on the differences in cellular stiffness. The sorting approach enabled analysis of the molecular distinctions between resistant and sensitive cells. Consequently, the role of multiple mechanisms of drug resistance was identified, including decreased sensitivity to apoptosis, enhanced metabolism, and extrusion of drugs, and, for the first time, the role of estrogen receptor in drug resistance of leukemia cells. To validate these findings, several inhibitors for the identified resistance pathways were tested with chemotherapy to increase cytotoxicity sevenfold. Thus, microfluidic sorting can identify molecular mechanisms of drug resistance to examine heterogeneous responses of cancers to therapies. PMID- 29445158 TI - ACKR2 in hematopoietic precursors as a checkpoint of neutrophil release and anti metastatic activity. AB - Atypical chemokine receptors (ACKRs) are regulators of leukocyte traffic, inflammation, and immunity. ACKR2 is a scavenger for most inflammatory CC chemokines and is a negative regulator of inflammation. Here we report that ACKR2 is expressed in hematopoietic precursors and downregulated during myeloid differentiation. Genetic inactivation of ACKR2 results in increased levels of inflammatory chemokine receptors and release from the bone marrow of neutrophils with increased anti-metastatic activity. In a model of NeuT-driven primary mammary carcinogenesis ACKR2 deficiency is associated with increased primary tumor growth and protection against metastasis. ACKR2 deficiency results in neutrophil-mediated protection against metastasis in mice orthotopically transplanted with 4T1 mammary carcinoma and intravenously injected with B16F10 melanoma cell lines. Thus, ACKR2 is a key regulator (checkpoint) of mouse myeloid differentiation and function and its targeting unleashes the anti-metastatic activity of neutrophils in mice. PMID- 29445160 TI - Optomechanics with a hybrid carbon nanotube resonator. AB - In just 20 years of history, the field of optomechanics has achieved impressive progress, stepping into the quantum regime just 5 years ago. Such remarkable advance relies on the technological revolution of nano-optomechanical systems, whose sensitivity towards thermal decoherence is strongly limited due to their ultra-low mass. Here we report a hybrid approach pushing nano-optomechanics to even lower scales. The concept relies on synthesising an efficient optical scatterer at the tip of singly clamped carbon nanotube resonators. We demonstrate high signal-to-noise motion readout and record force sensitivity, two orders of magnitude below the state of the art. Our work opens the perspective to extend quantum experiments and applications at room temperature. PMID- 29445161 TI - Anti-fouling graphene-based membranes for effective water desalination. AB - The inability of membranes to handle a wide spectrum of pollutants is an important unsolved problem for water treatment. Here we demonstrate water desalination via a membrane distillation process using a graphene membrane where water permeation is enabled by nanochannels of multilayer, mismatched, partially overlapping graphene grains. Graphene films derived from renewable oil exhibit significantly superior retention of water vapour flux and salt rejection rates, and a superior antifouling capability under a mixture of saline water containing contaminants such as oils and surfactants, compared to commercial distillation membranes. Moreover, real-world applicability of our membrane is demonstrated by processing sea water from Sydney Harbour over 72 h with macroscale membrane size of 4 cm2, processing ~0.5 L per day. Numerical simulations show that the channels between the mismatched grains serve as an effective water permeation route. Our research will pave the way for large-scale graphene-based antifouling membranes for diverse water treatment applications. PMID- 29445162 TI - MYCN drives glutaminolysis in neuroblastoma and confers sensitivity to an ROS augmenting agent. AB - Heightened aerobic glycolysis and glutaminolysis are characteristic metabolic phenotypes in cancer cells. Neuroblastoma (NBL), a devastating pediatric cancer, is featured by frequent genomic amplification of MYCN, a member of the Myc oncogene family that is primarily expressed in the early stage of embryonic development and required for neural crest development. Here we report that an enriched glutaminolysis gene signature is associated with MYCN amplification in children with NBL. The partial knockdown of MYCN suppresses glutaminolysis in NBL cells. Conversely, forced overexpression of MYCN in neural crest progenitor cells enhances glutaminolysis. Importantly, glutaminolysis induces oxidative stress by producing reactive oxygen species (ROS), rendering NBL cells sensitive to ROS augmentation. Through a small-scale metabolic-modulator screening, we have found that dimethyl fumarate (DMF), a Food and Drug Administration-approved drug for multiple sclerosis, suppresses NBL cell proliferation in vitro and tumor growth in vivo. DMF suppresses NBL cell proliferation through inducing ROS and subsequently suppressing MYCN expression, which is rescued by an ROS scavenger. Our findings suggest that the metabolic modulation and ROS augmentation could be used as novel strategies in treating NBL and other MYC-driven cancers.

AB - Down syndrome (DS) is caused by the presence of a supernumerary copy of the human chromosome 21 (Hsa21) and is the most frequent genetic cause of intellectual disability (ID). Key traits of DS are the distinctive facies and cognitive impairment. We conducted for the first time an analysis of the Nuclear Magnetic Resonance (NMR)-detectable part of the metabolome in plasma and urine samples, studying 67 subjects with DS and 29 normal subjects as controls selected among DS siblings. Multivariate analysis of the NMR metabolomic profiles showed a clear discrimination (up to of 80% accuracy) between the DS and the control groups. The univariate analysis of plasma and urine revealed a significant alteration for some interesting metabolites. Remarkably, most of the altered concentrations were consistent with the 3:2 gene dosage model, suggesting effects caused by the presence of three copies of Hsa21 rather than two: DS/normal ratio in plasma was 1.23 (pyruvate), 1.47 (succinate), 1.39 (fumarate), 1.33 (lactate), 1.4 (formate). Several significantly altered metabolites are produced at the beginning or during the Krebs cycle. Accounting for sex, age and fasting state did not significantly affect the main result of both multivariate and univariate analysis. PMID- 29445164 TI - Inactivation of TRPM7 kinase in mice results in enlarged spleens, reduced T-cell proliferation and diminished store-operated calcium entry. AB - T lymphocytes enlarge (blast) and proliferate in response to antigens in a multistep program that involves obligatory cytosolic calcium elevations. Store operated calcium entry (SOCE) pathway is the primary source of Ca2+ in these cells. Here, we describe a novel modulator of blastogenesis, proliferation and SOCE: the TRPM7 channel kinase. TRPM7 kinase-dead (KD) K1646R knock-in mice exhibited splenomegaly and impaired blastogenic responses elicited by PMA/ionomycin or anti-CD3/CD28 antibodies. Splenic T-cell proliferation in vitro was weaker in the mutant compared to wildtype littermates. TRPM7 current magnitudes in WT and KD mouse T cells were, however, similar. We tested the dependence of T-cell proliferation on external Ca2+ and Mg2+ concentrations. At a fixed [Mg2+o] of ~0.4 mM, Ca2+o stimulated proliferation with a steep concentration dependence and vice versa, at a fixed [Ca2+o] of ~0.4 mM, Mg2+o positively regulated proliferation but with a shallower dependence. Proliferation was significantly lower in KD mouse than in wildtype at all Ca2+ and Mg2+ concentrations. Ca2+ elevations elicited by anti-CD3 antibody were diminished in KD mutant T cells and SOCE measured in activated KD splenocytes was reduced. These results demonstrate that a functional TRPM7 kinase supports robust SOCE, blastogenesis and proliferation, whereas its inactivation suppresses these cellular events. PMID- 29445166 TI - Plastic pollution of the world's seas and oceans as a contemporary challenge in ocean governance. AB - The pervasive nature of marine plastic pollution was highlighted at the recent United Nations Environment Assembly. This meeting saw strong commitments for action, but at the same time reinforced the challenges for contemporary ocean governance in addressing marine plastic pollution. PMID- 29445165 TI - 53BP1 can limit sister-chromatid rupture and rearrangements driven by a distinct ultrafine DNA bridging-breakage process. AB - Chromosome missegregation acts as one of the driving forces for chromosome instability and cancer development. Here, we find that in human cancer cells, HeLa and U2OS, depletion of 53BP1 (p53-binding protein 1) exacerbates chromosome non-disjunction resulting from a new type of sister-chromatid intertwinement, which is distinct from FANCD2-associated ultrafine DNA bridges (UFBs) induced by replication stress. Importantly, the sister DNA intertwinements trigger gross chromosomal rearrangements through a distinct process, named sister-chromatid rupture and bridging. In contrast to conventional anaphase bridge-breakage models, we demonstrate that chromatid axes of the intertwined sister-chromatids rupture prior to the breakage of the DNA bridges. Consequently, the ruptured sister arms remain tethered and cause signature chromosome rearrangements, including whole-arm (Robertsonian-like) translocation/deletion and isochromosome formation. Therefore, our study reveals a hitherto unreported chromatid damage phenomenon mediated by sister DNA intertwinements that may help to explain the development of complex karyotypes in tumour cells. PMID- 29445167 TI - Prognostic significance of nephrectomy in metastatic renal cell carcinoma treated with systemic cytokine or targeted therapy: A 16-year retrospective analysis. AB - We compared progression-free survival (PFS) and overall survival (OS) among 292 metastatic renal cell carcinoma (mRCC) patients either undergoing nephrectomy (Nx, 61.6%) or not (non-Nx, 38.4%), stratified according to the MSKCC and Heng risk models, treated with either immunotherapy (IT, 45.2%) or targeted therapy (TT, 54.8%) between 2000 and 2015. During the follow-up duration of 16.6 months, PFS/OS of the Nx (6.0/30 months) and non-Nx (3.0/6.0 months) groups were significantly different despite differences among baseline parameters (p < 0.05). The intermediate- and poor-risk patients defined using either model showed significantly longer PFS and OS in the Nx group than in the non-Nx group (p < 0.05). After stratifying groups by systemic therapy and risk models, both the Nx and non-Nx groups showed no significant differences in intermediate and poor-risk models (p > 0.05). In both synchronous and metachronous mRCC patients, both PFS and OS showed similar survivals; the Nx group had significantly longer PFS and OS than the non-Nx group, even after considering each systemic therapy and prognostic model. Nx showed a significant positive benefit in PFS and OS compared to no Nx upon patient stratification according to the MSKCC and Heng risk models. The metastatic type did not significantly affect survival between the two groups. PMID- 29445168 TI - Biomimetic light-harvesting funnels for re-directioning of diffuse light. AB - Efficient sunlight harvesting and re-directioning onto small areas has great potential for more widespread use of precious high-performance photovoltaics but so far intrinsic solar concentrator loss mechanisms outweighed the benefits. Here we present an antenna concept allowing high light absorption without high reabsorption or escape-cone losses. An excess of randomly oriented pigments collects light from any direction and funnels the energy to individual acceptors all having identical orientations and emitting ~90% of photons into angles suitable for total internal reflection waveguiding to desired energy converters (funneling diffuse-light re-directioning, FunDiLight). This is achieved using distinct molecules that align efficiently within stretched polymers together with others staying randomly orientated. Emission quantum efficiencies can be >80% and single-foil reabsorption <0.5%. Efficient donor-pool energy funneling, dipole re orientation, and ~1.5-2 nm nearest donor-acceptor transfer occurs within hundreds to ~20 ps. Single-molecule 3D-polarization experiments confirm nearly parallel emitters. Stacked pigment selection may allow coverage of the entire solar spectrum. PMID- 29445169 TI - Shape anisotropy revisited in single-digit nanometer magnetic tunnel junctions. AB - Nanoscale magnetic tunnel junctions play a pivotal role in magnetoresistive random access memories. Successful implementation depends on a simultaneous achievement of low switching current for the magnetization switching by spin transfer torque and high thermal stability, along with a continuous reduction of junction size. Perpendicular easy-axis CoFeB/MgO stacks possessing interfacial anisotropy have paved the way down to 20-nm scale, below which a new approach needs to be explored. Here we show magnetic tunnel junctions that satisfy the requirements at ultrafine scale by revisiting shape anisotropy, which is a classical part of magnetic anisotropy but has not been fully utilized in the current perpendicular systems. Magnetization switching solely driven by current is achieved for junctions smaller than 10 nm where sufficient thermal stability is provided by shape anisotropy without adopting new material systems. This work is expected to push forward the development of magnetic tunnel junctions toward single-digit nm-scale nano-magnetics/spintronics. PMID- 29445170 TI - BRM270 inhibits cancer stem cell maintenance via microRNA regulation in chemoresistant A549 lung adenocarcinoma cells. AB - Chemotherapy is a standard treatment for non-small-cell lung cancer (NSCLC). However, the dose-limiting toxicity of drugs and the development of chemoresistance are major clinical challenges to successful management of NSCLC. Asian traditional medicine is gaining global attention as a non-toxic alternative to chemotherapy. BRM270 is an extract formulated from seven Asian medicinal plants that has been shown to inhibit tumor cell proliferation in diverse cancer types. We previously demonstrated that BRM270 suppresses tumorigenesis by negatively regulating nuclear factor-kappaB signaling in multidrug-resistant cancer stem cells (CSCs). In this study we report that the growth, migration, and invasion of normal human lung adenocarcinoma cells and their chemoresistant derivatives was inhibited by BRM270 treatment. Notably, BRM270 was found to modulate CSC self-renewal and tumor-initiating capacity via positive regulation of the miRNA-128. Thus, combination therapy with miRNA-128 and BRM270 may be an effective treatment strategy for chemoresistant NSCLC. PMID- 29445171 TI - Electrophysiological evidence of memory-based detection of auditory regularity violations in anesthetized mice. AB - In humans, automatic change detection is reflected by an electrical brain response called mismatch negativity (MMN). Mismatch response is also elicited in mice, but it is unclear to what extent it is functionally similar to human MMN. We investigated this possible similarity by recording local field potentials from the auditory cortex of anesthetized mice. First, we tested whether the response to stimulus changes reflected the detection of regularity violations or adaptation to standard stimuli. Responses obtained from an oddball condition, where occasional changes in frequency were presented amongst of a standard sound, were compared to responses obtained from a control condition, where no regularities existed. To test whether the differential response to the deviant sounds in the oddball condition is dependent on sensory memory, responses from the oddball condition using 375 ms and 600 ms inter-stimulus intervals (ISI) were compared. We found a differential response to deviant sounds which was larger with the shorter than the longer ISI. Furthermore, the oddball deviant sound elicited larger response than the same sound in the control condition. These results demonstrate that the mismatch response in mice reflects detection of regularity violations and sensory memory function, as the human MMN. PMID- 29445172 TI - Rational cell culture optimization enhances experimental reproducibility in cancer cells. AB - Optimization of experimental conditions is critical in ensuring robust experimental reproducibility. Through detailed metabolomic analysis we found that cell culture conditions significantly impacted on glutaminase (GLS1) sensitivity resulting in variable sensitivity and irreproducibility in data. Baseline metabolite profiling highlighted that untreated cells underwent significant changes in metabolic status. Both the extracellular levels of glutamine and lactate and the intracellular levels of multiple metabolites changed drastically during the assay. We show that these changes compromise the robustness of the assay and make it difficult to reproduce. We discuss the implications of the cells' metabolic environment when studying the effects of perturbations to cell function by any type of inhibitor. We then devised 'metabolically rationalized standard' assay conditions, in which glutaminase-1 inhibition reduced glutamine metabolism differently in both cell lines assayed, and decreased the proliferation of one of them. The adoption of optimized conditions such as the ones described here should lead to an improvement in reproducibility and help eliminate false negatives as well as false positives in these assays. PMID- 29445173 TI - Tuning piezoelectric properties through epitaxy of La2Ti2O7 and related thin films. AB - Current piezoelectric sensors and actuators are limited to operating temperatures less than ~200 degrees C due to the low Curie temperature of the piezoelectric material. Strengthening the piezoelectric coupling of high-temperature piezoelectric materials, such as La2Ti2O7 (LTO), would allow sensors to operate across a broad temperature range. The crystalline orientation and piezoelectric coupling direction of LTO thin films can be controlled by epitaxial matching to SrTiO3(001), SrTiO3(110), and rutile TiO2(110) substrates via pulsed laser deposition. The structure and phase purity of the films are investigated by x-ray diffraction and scanning transmission electron microscopy. Piezoresponse force microscopy is used to measure the in-plane and out-of-plane piezoelectric coupling in the films. The strength of the out-of-plane piezoelectric coupling can be increased when the piezoelectric direction is rotated partially out-of plane via epitaxy. The strongest out-of-plane coupling is observed for LTO/STO(001). Deposition on TiO2(110) results in epitaxial La2/3TiO3, an orthorhombic perovskite of interest as a microwave dielectric material and an ion conductor. La2/3TiO3 can be difficult to stabilize in bulk form, and epitaxial stabilization on TiO2(110) is a promising route to realize La2/3TiO3 for both fundamental studies and device applications. Overall, these results confirm that control of the crystalline orientation of epitaxial LTO-based materials can govern the resulting functional properties. PMID- 29445175 TI - A novel autophagy inhibitor berbamine blocks SNARE-mediated autophagosome lysosome fusion through upregulation of BNIP3. AB - Increasing evidences reveal that autophagy inhibitor could enhance the effect of chemotherapy to cancer. However, few autophagy inhibitors are currently approved for clinical application in humans. Berbamine (BBM) is a natural compound extracted from traditional Chinese medicine that is widely used for treatment of a variety of diseases without any obvious side effects. Here we found that BBM is a novel auophagy inhibitor, which potently induced the accumulation of autophagosomes by inhibiting autophagosome-lysosome fusion in human breast cancer cells. Mechanistically, we found that BBM blocked autophagosome-lysosome fusion by inhibiting the interaction of SNAP29 and VAMP8. Furthermore, BBM induced upregulation of BNIP3 and the interaction between SNAP29 and BNIP3. BNIP3 depletion or SNAP29 overexpression abrogated BBM-mediated blockade of autophagosome-lysosome fusion through the interaction between SNAP29 and VAMP8, whereas BNIP3 overexpression blocked autophagosome-lysosome fusion through inhibition of the interaction between SNAP29 and VAMP8. These findings suggest that upregulation of BNIP3 and interaction between BNIP3 and SNAP29 could be involved in BBM-mediated blockade of autophagosome-lysosome fusion through inhibition of the interaction between SNAP29 and VAMP8. Our findings identify the critical role of BNIP3 in blockade of autophagosome-lysosome fusion mediated by BBM, and suggest that BBM could potentially be further developed as a novel autophagy inhibitor, which could enhance the effect of chemotherapy to cancer. PMID- 29445174 TI - A spatial gradient of bacterial diversity in the human oral cavity shaped by salivary flow. AB - Spatial and temporal patterns in microbial communities provide insights into the forces that shape them, their functions and roles in health and disease. Here, we used spatial and ecological statistics to analyze the role that saliva plays in structuring bacterial communities of the human mouth using >9000 dental and mucosal samples. We show that regardless of tissue type (teeth, alveolar mucosa, keratinized gingiva, or buccal mucosa), surface-associated bacterial communities vary along an ecological gradient from the front to the back of the mouth, and that on exposed tooth surfaces, the gradient is pronounced on lingual compared to buccal surfaces. Furthermore, our data suggest that this gradient is attenuated in individuals with low salivary flow due to Sjogren's syndrome. Taken together, our findings imply that salivary flow influences the spatial organization of microbial communities and that biogeographical patterns may be useful for understanding host physiological processes and for predicting disease. PMID- 29445176 TI - Thermally-Conductive and Mechanically-Robust Graphene Nanoplatelet Reinforced UO2 Composite Nuclear Fuels. AB - Low thermal transport behavior along the radial direction of nuclear fuel pellets and pellet-cladding mechanical interaction significantly impact fuel performance and the safety of current nuclear energy systems. Here we report a new strategy of advanced fuel design in which highly thermally-conductive and mechanically robust graphene nanoplatelets are incorporated into UO2 fuel matrix to improve fuel thermal-mechanical properties. The 2D geometry of the graphene nanoplatelets enables a unique lamellar structure upon fuel consolidation by spark plasma sintering. The thermal conductivity along the radial direction of the sintered fuel pellets at room temperature reaches 12.7 and 19.1 wm-1K-1 at 1 wt.% and 5 wt.% loadings of the graphene nanoplatelets, respectively, representing at least 74% and 162% enhancements as compared to pure UO2 fuel pellets. Indentation testing suggests great capability of the 2D graphene nanoplatelets to deflect and pin crack propagation, drastically improving the crack propagation resistance of fuel matrix. The estimated indentation fracture toughness reaches 3.5 MPa.m1/2 by 1 wt.% loading of graphene nano-platelets, representing a 150% improvement over 1.4 MPa.m1/2 for pure UO2 fuel pellets. Isothermal annealing of the composite fuel indicates that the graphene nano-platelet is able to retain its structure and properties against reaction with UO2 matrix up to 1150 degrees C. PMID- 29445177 TI - Validating a breast cancer score in Spanish women. The MCC-Spain study. AB - A breast-risk score, published in 2016, was developed in white-American women using 92 genetic variants (GRS92), modifiable and non-modifiable risk factors. With the aim of validating the score in the Spanish population, 1,732 breast cancer cases and 1,910 controls were studied. The GRS92, modifiable and non modifiable risk factor scores were estimated via logistic regression. SNPs without available genotyping were simulated as in the aforementioned 2016 study. The full model score was obtained by combining GRS92, modifiable and non modifiable risk factor scores. Score performances were tested via the area under the ROC curve (AUROC), net reclassification index (NRI) and integrated discrimination improvement (IDI). Compared with non-modifiable and modifiable factor scores, GRS92 had higher discrimination power (AUROC: 0.6195, 0.5885 and 0.5214, respectively). Adding the non-modifiable factor score to GRS92 improved patient classification by 23.6% (NRI = 0.236), while the modifiable factor score only improved it by 7.2%. The full model AUROC reached 0.6244. A simulation study showed the ability of the full model for identifying women at high risk for breast cancer. In conclusion, a model combining genetic and risk factors can be used for stratifying women by their breast cancer risk, which can be applied to individualizing genetic counseling and screening recommendations. PMID- 29445178 TI - The effect of Clostridium butyricum on symptoms and fecal microbiota in diarrhea dominant irritable bowel syndrome: a randomized, double-blind, placebo-controlled trial. AB - Irritable bowel syndrome (IBS) is a common disorder in gastrointestinal system and impairs the quality of life of the patients. Clostridium butyricum (CB) is a probiotics that has been used in several gastrointestinal diseases. The efficacy of CB in treating IBS is still unknown. This prospective, multi-centre, randomized, double-blind, placebo-controlled trial aimed to assess the efficacy and safety of CB in treating diarrhea-predominant IBS (IBS-D) and analyze the fecal microbiota after treatment. Two hundred patients with IBS-D were recruited and were given CB or placebo for 4 weeks. End points included change from baseline in IBS symptoms, quality of life, stool consistency and frequency. Compared with placebo, CB is effective in improving the overall IBS-D symptoms ( 62.12 +/- 74.00 vs. -40.74 +/- 63.67, P = 0.038) as well as quality of life (7.232 +/- 14.06 vs. 3.159 +/- 11.73, P = 0.032) and stool frequency (-1.602 +/- 1.416 vs. -1.086 +/- 1.644, P = 0.035). The responder rates are found higher in CB compared with the placebo (44.76% vs. 30.53%, P = 0.042). The change in fecal microbiota was analyzed and function pathways of CB in treating IBS-D were predicted. In conclusion, CB improves overall symptoms, quality of life and stool frequency in IBS-D patients and is considered to be used as a probiotics in treating IBS-D clinically. PMID- 29445179 TI - Long noncoding RNA GAS5 promotes bladder cancer cells apoptosis through inhibiting EZH2 transcription. AB - Aberrant expression of long noncoding RNA GAS5 in bladder cancer (BC) cells was identified in recent studies. However, the regulatory functions and underlying molecular mechanisms of GAS5 in BC development remain unclear. Here, we confirmed that there was a negative correlation between GAS5 level and bladder tumor clinical stage. Functionally, overexpression of GAS5 reduced cell viability and induced cell apoptosis in T24 and EJ bladder cancer cells. Mechanistically, GAS5 effectively repressed EZH2 transcription by directly interacting with E2F4 and recruiting E2F4 to EZH2 promoter. We previously reported that miR-101 induced the apoptosis of BC cells by inhibiting the expression of EZH2. Interestingly, the present study showed that downregulation of EZH2 by GAS5 resulted in overexpression of miR-101 in T24 and EJ cells. Furthermore, the level of GAS5 was increased under the treatment of Gambogic acid (GA), a promising natural anti cancer compound, whereas knockdown of GAS5 suppressed the inhibitory effect of GA on cell viability and abolished GA-induced apoptosis in T24 and EJ cells. Taken together, our findings demonstrated a tumor-suppressor role of GAS5 by inhibiting EZH2 on transcriptional level, and additionally provided a novel therapeutic strategy for treating human bladder cancer. PMID- 29445182 TI - Terpene Composition Complexity Controls Secondary Organic Aerosol Yields from Scots Pine Volatile Emissions. AB - Secondary organic aerosol (SOA) impact climate by scattering and absorbing radiation and contributing to cloud formation. SOA models are based on studies of simplified chemical systems that do not account for the chemical complexity in the atmosphere. This study investigated SOA formation from a mixture of real Scots pine (Pinus sylvestris) emissions including a variety of monoterpenes and sesquiterpenes. SOA generation was characterized from different combinations of volatile compounds as the plant emissions were altered with an herbivore stress treatment. During active herbivore feeding, monoterpene and sesquiterpene emissions increased, but SOA mass yields decreased after accounting for absorption effects. SOA mass yields were controlled by sesquiterpene emissions in healthy plants. In contrast, SOA mass yields from stressed plant emissions were controlled by the specific blend of monoterpene emissions. Conservative estimates using a box model approach showed a 1.5- to 2.3-fold aerosol enhancement when the terpene complexity was taken into account. This enhancement was relative to the commonly used model monoterpene, "alpha-pinene". These results suggest that simplifying terpene complexity in SOA models could lead to underpredictions in aerosol mass loading. PMID- 29445181 TI - Interactions between predation and disturbances shape prey communities. AB - Ecological disturbances are important drivers of biodiversity patterns. Many biodiversity studies rely on endpoint measurements instead of following the dynamics that lead to those outcomes and testing ecological drivers individually, often considering only a single trophic level. Manipulating multiple factors (biotic and abiotic) in controlled settings and measuring multiple descriptors of multi-trophic communities could enlighten our understanding of the context dependency of ecological disturbances. Using model microbial communities, we experimentally tested the effects of imposed disturbances (i.e. increased dilution simulating density-independent mortality as press or pulse disturbances coupled with resource deprivation) on bacterial abundance, diversity and community structure in the absence or presence of a protist predator. We monitored the communities immediately before and after imposing the disturbance and four days after resuming the pre-disturbance dilution regime to infer resistance and recovery properties. The results highlight that bacterial abundance, diversity and community composition were more affected by predation than by disturbance type, resource loss or the interaction of these factors. Predator abundance was strongly affected by the type of disturbance imposed, causing temporary relief of predation pressure. Importantly, prey community composition differed significantly at different phases, emphasizing that endpoint measurements are insufficient for understanding the recovery of communities. PMID- 29445180 TI - Myeloid-derived interleukin-1beta drives oncogenic KRAS-NF-kappaBeta addiction in malignant pleural effusion. AB - Malignant pleural effusion (MPE) is a frequent metastatic manifestation of human cancers. While we previously identified KRAS mutations as molecular culprits of MPE formation, the underlying mechanism remained unknown. Here, we determine that non-canonical IKKalpha-RelB pathway activation of KRAS-mutant tumor cells mediates MPE development and this is fueled by host-provided interleukin IL 1beta. Indeed, IKKalpha is required for the MPE-competence of KRAS-mutant tumor cells by activating non-canonical NF-kappaB signaling. IL-1beta fuels addiction of mutant KRAS to IKKalpha resulting in increased CXCL1 secretion that fosters MPE-associated inflammation. Importantly, IL-1beta-mediated NF-kappaB induction in KRAS-mutant tumor cells, as well as their resulting MPE-competence, can only be blocked by co-inhibition of both KRAS and IKKalpha, a strategy that overcomes drug resistance to individual treatments. Hence we show that mutant KRAS facilitates IKKalpha-mediated responsiveness of tumor cells to host IL-1beta, thereby establishing a host-to-tumor signaling circuit that culminates in inflammatory MPE development and drug resistance. PMID- 29445183 TI - Reducing risk and improving maternal perspective-taking and empathy using virtual embodiment. AB - The ability to perspective-take (cognitive awareness of another's state) and empathise (emotional/affective response) are important characteristics for sensitive, co-operative and constructive parenting, which assists in developing adaptive functioning for children. For the first time, immersive virtual reality was used to place parents in the position of a child in order to assess impact on perspective-taking and empathy. This novel study was conducted with 20 non-high risk Spanish mothers (a pilot study with 12 mothers is reported in supplementary files). Mothers were virtually embodied as a 4-year-old child, experienced from the first-person perspective and with virtual and real body movements synchronised. They interacted with a 'mother avatar', which responded either in a Positive or Negative way. Participants reported a strong body ownership illusion for the child body that led to cognitive, emotional and physical reactions. Experiencing negative maternal behavior increased levels of empathy. In addition, the Negative mother led to increased feelings of fear of violence. Physiological data indicated greater stress in the Negative than Positive condition. Although further research is required to assess the effectiveness of such methods, any improvement in empathy that leads to a change in parenting behavior has the potential to impact on developmental outcomes for children. PMID- 29445184 TI - Parental micronutrient deficiency distorts liver DNA methylation and expression of lipid genes associated with a fatty-liver-like phenotype in offspring. AB - Micronutrient status of parents can affect long term health of their progeny. Around 2 billion humans are affected by chronic micronutrient deficiency. In this study we use zebrafish as a model system to examine morphological, molecular and epigenetic changes in mature offspring of parents that experienced a one-carbon (1-C) micronutrient deficiency. Zebrafish were fed a diet sufficient, or marginally deficient in 1-C nutrients (folate, vitamin B12, vitamin B6, methionine, choline), and then mated. Offspring livers underwent histological examination, RNA sequencing and genome-wide DNA methylation analysis. Parental 1 C micronutrient deficiency resulted in increased lipid inclusion and we identified 686 differentially expressed genes in offspring liver, the majority of which were downregulated. Downregulated genes were enriched for functional categories related to sterol, steroid and lipid biosynthesis, as well as mitochondrial protein synthesis. Differential DNA methylation was found at 2869 CpG sites, enriched in promoter regions and permutation analyses confirmed the association with parental feed. Our data indicate that parental 1-C nutrient status can persist as locus specific DNA methylation marks in descendants and suggest an effect on lipid utilization and mitochondrial protein translation in F1 livers. This points toward parental micronutrients status as an important factor for offspring health and welfare. PMID- 29445186 TI - Current-induced magnetization switching in atom-thick tungsten engineered perpendicular magnetic tunnel junctions with large tunnel magnetoresistance. AB - Perpendicular magnetic tunnel junctions based on MgO/CoFeB structures are of particular interest for magnetic random-access memories because of their excellent thermal stability, scaling potential, and power dissipation. However, the major challenge of current-induced switching in the nanopillars with both a large tunnel magnetoresistance ratio and a low junction resistance is still to be met. Here, we report spin transfer torque switching in nano-scale perpendicular magnetic tunnel junctions with a magnetoresistance ratio up to 249% and a resistance area product as low as 7.0 Omega um2, which consists of atom-thick W layers and double MgO/CoFeB interfaces. The efficient resonant tunnelling transmission induced by the atom-thick W layers could contribute to the larger magnetoresistance ratio than conventional structures with Ta layers, in addition to the robustness of W layers against high-temperature diffusion during annealing. The critical switching current density could be lower than 3.0 MA cm-2 for devices with a 45-nm radius. PMID- 29445185 TI - Iron Overload Accelerates the Progression of Diabetic Retinopathy in Association with Increased Retinal Renin Expression. AB - Diabetic retinopathy (DR) is a leading cause of blindness among working-age adults. Increased iron accumulation is associated with several degenerative diseases. However, there are no reports on the status of retinal iron or its implications in the pathogenesis of DR. In the present study, we found that retinas of type-1 and type-2 mouse models of diabetes have increased iron accumulation compared to non-diabetic retinas. We found similar iron accumulation in postmortem retinal samples from human diabetic patients. Further, we induced diabetes in HFE knockout (KO) mice model of genetic iron overload to understand the role of iron in the pathogenesis of DR. We found increased neuronal cell death, vascular alterations and loss of retinal barrier integrity in diabetic HFE KO mice compared to diabetic wildtype mice. Diabetic HFE KO mouse retinas also exhibited increased expression of inflammation and oxidative stress markers. Severity in the pathogenesis of DR in HFE KO mice was accompanied by increase in retinal renin expression mediated by G-protein-coupled succinate receptor GPR91. In light of previous reports implicating retinal renin-angiotensin system in DR pathogenesis, our results reveal a novel relationship between diabetes, iron and renin-angiotensin system, thereby unraveling new therapeutic targets for the treatment of DR. PMID- 29445187 TI - Adult male mice exposure to nonylphenol alters courtship vocalizations and mating. AB - The neural circuitry processing male sexual behavior is tightly regulated by testosterone and its neural metabolite estradiol. The present study evaluated the effects of adult exposure to low doses of nonylphenol (NP), a widespread environmental contaminant, on the neuroendocrine regulation of testosterone and expression of sexual behavior. Oral exposure of C57BL/6J males to NP (0.5, 5 or 50 MUg/kg/day) for 4 weeks did not affect circulating levels of testosterone or the kisspeptin system, a key regulator of the gonadotropic axis. In contrast, mice exposed to NP at 5 MUg/kg/day emitted an increased number and duration of ultrasonic vocalizations, took longer to reach ejaculation and showed increased number of mounts, intromissions and thrusts. This was associated with normal olfactory preference and locomotor activity, and increased anxiety level. Analysis of the neural circuitry that underlies sexual behavior showed changes in the number of cells expressing androgen and estrogen receptors in males exposed to NP at 5 MUg/kg/day. The neural circuitry underlying sexual behavior is thus highly sensitive to adult exposure to NP. Furthermore, almost all the observed effects were induced at 5 MUg/kg/day of NP, indicating that this endocrine disrupter triggers a non-monotonic response in the adult male mouse brain. PMID- 29445188 TI - Daily circadian misalignment impairs human cognitive performance task dependently. AB - Shift work increases the risk for human errors, such that drowsiness due to shift work has contributed to major industrial disasters, including Space Shuttle Challenger, Chernobyl and Alaska Oil Spill disasters, with extraordinary socio economical costs. Overnight operations pose a challenge because our circadian biology inhibits cognitive performance at night. Yet how the circadian system modulates cognition over multiple days under realistic shift work conditions remains to be established. Importantly, because task-specific cognitive brain regions show different 24-h circadian dynamics, we hypothesize that circadian misalignment impacts cognition task-dependently. Using a biologically-driven paradigm mimicking night shift work, with a randomized, cross-over design, we show that misalignment between the circadian pacemaker and behavioral/environmental cycles increases cognitive vulnerability on sustained attention, cognitive throughput, information processing and visual-motor performance over multiple days, compared to circadian alignment (day shifts). Circadian misalignment effects are task-dependent: while they acutely impair sustained attention with recovery after 3-days, they progressively hinder daily learning. Individuals felt sleepier during circadian misalignment, but they did not rate their performance as worse. Furthermore, circadian misalignment effects on sustained attention depended on prior sleep history. Collectively, daily circadian misalignment may provide an important biological framework for developing countermeasures against adverse cognitive effects in shift workers. PMID- 29445189 TI - STK17B promotes carcinogenesis and metastasis via AKT/GSK-3beta/Snail signaling in hepatocellular carcinoma. AB - Hepatocellular carcinoma (HCC) is a lethal malignancy worldwide with frequent intrahepatic and distant metastasis. Elucidating the underlying molecular mechanism that modulates HCC progression is critical for exploring novel therapeutic strategies. Serine/Threonine Kinase 17B (STK17B) is upregulated in HCC tissues, but its role in HCC progression remains elusive. In the present studies, we reported that STK17B had a critical role in HCC progression. STK17B was significantly upregulated in HCC cell lines and specimens, and patients with ectopic STK17B expression characterized with poor clinicopathological features. In vitro and in vivo assay demonstrated that inhibition of STK17B markedly inhibits HCC tumorigenesis and metastasis, while STK17B overexpression promoted these processes. Furthermore, we found that STK17B promoted EMT process via activating AKT/GSK-3beta/Snail signal pathway, and miR-455-3p was identified as the upstream regulator of STK17B. Combination of high level of STK17B and low level of miR-455-3p predicted poor prognosis with higher accuracy for HCC patients. In conclusion, our research demonstrated that STK17B promotes HCC progression, induces EMT process via activating AKT/GSK-3beta/Snail signal and predicts poor prognosis in HCC. PMID- 29445190 TI - The chemokine receptor CCR10 promotes inflammation-driven hepatocarcinogenesis via PI3K/Akt pathway activation. AB - G-protein-coupled receptor (GPCR)-related proteins are dysregulated and the GPCR CC-chemokine receptor 10 (CCR10) is significantly upregulated in inflammation driven HCC. However, CCR10's role in inflammation-driven hepatocarcinogenesis remains unknown. The aim of this study was to evaluate the role of CCR10 in inflammation-driven hepatocarcinogenesis. Via a targeted gene expression microarray screening alterations in GPCR family gene expression, we found CCR10 to be significantly upregulated in hepatocytes isolated from inflammation-driven human HCC tumors and matching paracancerous tissues. Tetrachloromethane (CCl4) induced and diethylnitrosamine (DEN)-induced murine models of inflammatory hepatocarcinogenesis displayed significant hepatocellular TNF and CCR10 upregulation. Exogenous TNF applied to HepG2 and LO2 cell lines as well as wild type (WT) mice significantly upregulated hepatocellular CCR10 expression, Akt phosphorylation, PCNA expression, and hepatocellular proliferation. Additionally, exogenous TNF significantly upregulated secretion of the natural CCR10 ligand agonist CCL28 from both cell lines. Transgenic CCR10-knockout (CCR10 KO) in DEN treated mice significantly increased hepatocellular apoptosis levels and significantly lowered compensatory hepatocellular proliferation but did not affect upstream TNF expression. In addition, DEN-treated CCR10 KO mice showed a significantly lower liver weight/body weight ratio, significantly lower liver tumor incidence, and significantly smaller tumors. Moreover, exogenous CCR10 expression significantly raised xenograft tumor growth in Balb/c nude mice. In vitro, CCR10 transfection or CCL28 treatment in HepG2 and LO2 cell lines significantly increased Akt phosphorylation, PCNA expression, and cell proliferation, while CCR10 silencing or Akt inhibition produced the opposite effects. In vivo, hepatocytes isolated from HCC tumor tissue and matching paracancerous tissue in DEN-treated CCR10 KO mice showed significantly lower Akt phosphorylation and PCNA expression relative to WT hepatocytes. In conclusion, inflammation-induced TNF promotes hepatocellular CCR10 expression and downstream PI3K/Akt-mediated hepatocarcinogenesis. CCR10 appears to function as a linkage between TNF stimulation and downstream PI3K/Akt pathway activation and shows promise as a potential therapeutic target for inflammation-driven HCC. PMID- 29445191 TI - Minute hands of clocks indicating the same time are not perceived as haptically parallel. AB - Many studies have already shown that a large idiosyncratic orientation difference is needed to perceive two bars that are far apart as haptically parallel. There exist also strong indications that if such bars are imagined to be minute hands of clocks, errors made in clock time estimates and clock time settings are much smaller. The current study investigated this seemingly discrepancy. Participants partook in three experiments: parallel setting, clock time estimate and clock time setting, in this order. As the individual parallel settings were used in the subsequent clock time estimate experiment, and the estimated clock times in the clock time setting experiment, the deviations could be compared directly. In all three experiments, the deviations were systematic and idiosyncratic, and consistent with a biasing influence of an egocentric reference frame. However, the deviations in the two clock time experiments were indeed much smaller than in the parallel setting experiment. Task instruction and strengthened focus on an allocentric reference frame are the most likely explanations. These findings provide fundamental insights in the processing of spatial information. Taking these findings into account when designing haptic devices may make these more intuitive. PMID- 29445192 TI - SPRY2 is a novel MET interactor that regulates metastatic potential and differentiation in rhabdomyosarcoma. AB - Rhabdomyosarcoma (RMS) is a predominantly pediatric soft-tissue cancer where the tumor cells exhibit characteristics of the developing skeletal muscle, and the two most common sub-types are embryonal and alveolar RMS. Elevated activation of the receptor tyrosine kinase (RTK) MET is frequent in RMS and is thought to cause increased tumor metastasis and lack of differentiation. However, the reasons underlying dysregulated MET expression and activation in RMS are not well understood. Therefore, we explored the role of Sprouty 2 (SPRY2), a modulator of RTK signaling, in regulating MET. We identify SPRY2 as a novel MET interactor that colocalizes with and binds MET in both embryonal and alveolar RMS. We find that depletion of SPRY2 leads to MET degradation, resulting in reduced migratory and clonogenic potential, and induction of differentiation in both embryonal and alveolar RMS, outcomes that are identical to depletion of MET. Activation of the ERK/MAPK pathway, known to be crucial for regulating cell migration and whose inhibition is required for myogenic differentiation, was downregulated upon depletion of MET or SPRY2. This provides a direct connection to the decreased migration and induction of differentiation upon depletion of MET or SPRY2. Thus, these data indicate that SPRY2 interacts with MET and stabilizes it in order to maintain signaling downstream of MET, which keeps the ERK/MAPK pathway active, resulting in metastatic potential and inhibition of differentiation in RMS. Our results identify a novel mechanism by which MET signaling is stabilized in RMS, and is a potential target for therapeutic intervention in RMS.

AB - Coastal wetlands are increasingly recognised for their pivotal role in mitigating the growing threats from cyclones (including hurricanes) in a changing climate. There is, however, insufficient information about the economic value of coastal wetlands for cyclone mitigation, particularly at regional scales. Analysis of data from 1990-2012 shows that the variation of cyclone frequencies is related to EI Nino strength in the Pacific Ocean adjacent to Australia, but not China. Among the cyclones hitting the two countries, there are significant relationships between the ratio of total economic damage to gross domestic production (TD/GDP) and wetland area within cyclone swaths in Australia, and wetland area plus minimum cyclone pressure despite a weak relationship in China. The TD/GDP ratio is significantly higher in China than in Australia. Despite their extensive and growing occurrence, seawalls in China appear not to play a critical role in cyclone mitigation, and cannot replace coastal wetlands, which provide other efficient ecosystem services. The economic values of coastal wetlands in Australia and China are respectively estimated at US$52.88 billion and 198.67 billion yr-1 for cyclone mitigation, albeit with large within-country geographic variation. This study highlights the urgency to integrate this value into existing valuations of coastal wetlands. PMID- 29445193 TI - Uncoupling FoxO3A mitochondrial and nuclear functions in cancer cells undergoing metabolic stress and chemotherapy. AB - While aberrant cancer cell growth is frequently associated with altered biochemical metabolism, normal mitochondrial functions are usually preserved and necessary for full malignant transformation. The transcription factor FoxO3A is a key determinant of cancer cell homeostasis, playing a dual role in survival/death response to metabolic stress and cancer therapeutics. We recently described a novel mitochondrial arm of the AMPK-FoxO3A axis in normal cells upon nutrient shortage. Here, we show that in metabolically stressed cancer cells, FoxO3A is recruited to the mitochondria through activation of MEK/ERK and AMPK, which phosphorylate serine 12 and 30, respectively, on FoxO3A N-terminal domain. Subsequently, FoxO3A is imported and cleaved to reach mitochondrial DNA, where it activates expression of the mitochondrial genome to support mitochondrial metabolism. Using FoxO3A-/- cancer cells generated with the CRISPR/Cas9 genome editing system and reconstituted with FoxO3A mutants being impaired in their nuclear or mitochondrial subcellular localization, we show that mitochondrial FoxO3A promotes survival in response to metabolic stress. In cancer cells treated with chemotherapeutic agents, accumulation of FoxO3A into the mitochondria promoted survival in a MEK/ERK-dependent manner, while mitochondrial FoxO3A was required for apoptosis induction by metformin. Elucidation of FoxO3A mitochondrial vs. nuclear functions in cancer cell homeostasis might help devise novel therapeutic strategies to selectively disable FoxO3A prosurvival activity. PMID- 29445195 TI - Ultra-high thermal effusivity materials for resonant ambient thermal energy harvesting. AB - Materials science has made progress in maximizing or minimizing the thermal conductivity of materials; however, the thermal effusivity-related to the product of conductivity and capacity-has received limited attention, despite its importance in the coupling of thermal energy to the environment. Herein, we design materials that maximize the thermal effusivity by impregnating copper and nickel foams with conformal, chemical-vapor-deposited graphene and octadecane as a phase change material. These materials are ideal for ambient energy harvesting in the form of what we call thermal resonators to generate persistent electrical power from thermal fluctuations over large ranges of frequencies. Theory and experiment demonstrate that the harvestable power for these devices is proportional to the thermal effusivity of the dominant thermal mass. To illustrate, we measure persistent energy harvesting from diurnal frequencies, extracting as high as 350 mV and 1.3 mW from approximately 10 degrees C diurnal temperature differences. PMID- 29445196 TI - On the origins of transport inefficiencies in mesoscopic networks. AB - A counter-intuitive behavior analogous to the Braess paradox is encountered in a two-terminal mesoscopic network patterned in a two-dimensional electron system (2DES). Decreasing locally the electron density of one channel of the network paradoxically leads to an increased network electrical conductance. Our low temperature scanning gate microscopy experiments reveal different occurrences of such puzzling conductance variations, thanks to tip-induced localized modifications of electron flow throughout the network's channels in the ballistic and coherent regime of transport. The robustness of the puzzling behavior is inspected by varying the global 2DES density, magnetic field and the tip-surface distance. Depending on the overall 2DES density, we show that either Coulomb Blockade resonances due to disorder-induced localized states or Fabry-Perot interferences tuned by the tip-induced electrostatic perturbation are at the origin of transport inefficiencies in the network, which are lifted when gradually closing one channel of the network with the tip. PMID- 29445197 TI - Differences in frontotemporal dysfunction during social and non-social cognition tasks between patients with autism spectrum disorder and schizophrenia. AB - Although literature evidence suggests deficits in social and non-social cognition in patients with autistic spectrum disorder (ASD) and schizophrenia (SCZ), the difference in neural correlates of the impairments between the two disorders has not been elucidated. We examined brain function in response to a non-social cognition and a social cognition task using functional near-infrared spectroscopy (fNIRS) in 13 patients with ASD, 15 patients with SCZ, and 18 healthy subjects. We assessed the brain function of participants using a verbal fluency task and an emotional facial recognition task. The patients with ASD showed significantly reduced brain activation in the left frontotemporal area during both tasks compared to healthy subjects. The patients with ASD with larger score in 'attention to detail' in the autism spectrum quotient showed lower activation of the left frontotemporal area during the two tasks. The patients with SCZ showed significantly reduced activation, compared to healthy subjects, and greater activation, compared to patients with ASD, in the area during the verbal fluency task. The patients with SCZ with more severe symptoms had lower brain activation during the task in this area. Our results suggest that two distinct areas are involved in the distinctive brain pathophysiology relevant to cognitive processing in patients with ASD and SCZ. PMID- 29445198 TI - Phase-tuning Metasurface for Circularly Polarized Broadside Radiation in Broadband. AB - Metasurface antennas (MAs) have been proposed as innovative alternatives to conventional bulky configurations for satellite applications because of their low profile, low cost, and high gain. The general method of surface impedance modulation for designing MAs is complicated, and achieving broad operation bandwidth remains a challenge because of its high dispersion response. We propose a novel and easy technique to control cylindrical surface waves radiated by a phase-tuning metasurface. Simultaneously, this technique exhibits a considerably wide working bandwidth. A detailed analysis of the radiation mechanism is discussed. A left-hand circularly polarized (LHCP) antenna and a right-hand circularly polarized (RHCP) antenna that are based on the phase-tuning metasurface are simulated and measured. The measured fractional 3-dB gain bandwidth and gain are higher than 17% and 15.57 dBi, respectively, which are consistent with the simulated results. Moreover, 30% 3-dB axial ratio is achieved for the LHCP and RHCP antennas. To the best knowledge of the authors, it is for the first time to realize a circularly polarized broadband MA by using the phase tuning mechanism. The approach can be regarded as a new starting point for antenna design, thereby paving the way for the development of broadband and low profile antennas for future satellite communication. PMID- 29445199 TI - Lack of T-bet reduces monocytic interleukin-12 formation and accelerates thrombus resolution in deep vein thrombosis. AB - The role of leukocytes in deep vein thrombosis (DVT) resolution is incompletely understood. We determined how depletion of lysozyme positive (LysM+) cells and a switched-off type 1 immune response influences thrombus resolution. DVT was induced in 12-week-old male mice by inferior vena cava (IVC) stenosis. Toxin mediated depletion of myeloid cells improved thrombus resolution in mice with Cre inducible expression of the diphtheria toxin receptor in LysM+ cells. This correlated with decreased CD45+ cells, a population shift of Gr-1+ to Gr-1- CD11b+ myelomonocytic cells (flow cytometry) and an increase in CC-chemokine ligand 2, interleukin-4 and interleukin-10 mRNA expressions. Tbx21-/- mice (lacking transcription factor T-bet and marked by an attenuated type 1 immune response) with DVT had faster thrombus resolution, a reduction of pro inflammatory Ly6Chi monocytes in thrombi and decreased interleukin-12p40 mRNA expression than control mice resulting in increased vascular endothelial growth factor mRNA expression and improved neovascularization of thrombotic veins. Transfer of Tbx21-/- bone marrow into irradiated Tbx21+/+ recipients lead to accelerated thrombus resolution with lower T-bet-dependent interleukin-12p40 mRNA levels following IVC-stenosis. We conclude that inhibition of Tbet+ interleukin 12 forming myelomonocytic cells accelerated thrombus resolution. Modulating the inflammatory immune response might be an approach to improve therapy of DVT. PMID- 29445201 TI - Magnetism and high magnetic-field-induced stability of alloy carbides in Fe-based materials. AB - Understanding the nature of the magnetic-field-induced precipitation behaviors represents a major step forward towards unravelling the real nature of interesting phenomena in Fe-based alloys and especially towards solving the key materials problem for the development of fusion energy. Experimental results indicate that the applied high magnetic field effectively promotes the precipitation of M23C6 carbides. We build an integrated method, which breaks through the limitations of zero temperature and zero external field, to concentrate on the dependence of the stability induced by the magnetic effect, excluding the thermal effect. We investigate the intimate relationship between the external field and the origins of various magnetics structural characteristics, which are derived from the interactions among the various Wyckoff sites of iron atoms, antiparallel spin of chromium and Fe-C bond distances. The high-magnetic-field-induced exchange coupling increases with the strength of the external field, which then causes an increase in the parallel magnetic moment. The stability of the alloy carbide M23C6 is more dependent on external field effects than thermal effects, whereas that of M2C, M3C and M7C3 is mainly determined by thermal effects. PMID- 29445200 TI - Impaired beta-arrestin recruitment and reduced desensitization by non-catechol agonists of the D1 dopamine receptor. AB - Selective activation of dopamine D1 receptors (D1Rs) has been pursued for 40 years as a therapeutic strategy for neurologic and psychiatric diseases due to the fundamental role of D1Rs in motor function, reward processing, and cognition. All known D1R-selective agonists are catechols, which are rapidly metabolized and desensitize the D1R after prolonged exposure, reducing agonist response. As such, drug-like selective D1R agonists have remained elusive. Here we report a novel series of selective, potent non-catechol D1R agonists with promising in vivo pharmacokinetic properties. These ligands stimulate adenylyl cyclase signaling and are efficacious in a rodent model of Parkinson's disease after oral administration. They exhibit distinct binding to the D1R orthosteric site and a novel functional profile including minimal receptor desensitization, reduced recruitment of beta-arrestin, and sustained in vivo efficacy. These results reveal a novel class of D1 agonists with favorable drug-like properties, and define the molecular basis for catechol-specific recruitment of beta-arrestin to D1Rs. PMID- 29445202 TI - Chemically induced Fermi level pinning effects of high-k dielectrics on graphene. AB - High-k materials such as Al2O3 and HfO2 are widely used as gate dielectrics in graphene devices. However, the effective work function values of metal gate in graphene FET are significantly deviated from their vacuum work function, which is similar to the Fermi level pinning effect observed in silicon MOSFETs with high-k dielectric. The degree of deviation represented by a pinning factor was much worse with HfO2 (pinning factor (S) = 0.19) than with Al2O3 (S = 0.69). We propose that the significant pinning-like behaviors induced by HfO2 are correlated with the oxygen exchange reactions occurred at the interface of graphene and HfO2. PMID- 29445203 TI - Effects of Touch Location and Intensity on Interneurons of the Leech Local Bend Network. AB - Touch triggers highly precise behavioural responses in the leech. The underlying network of this so-called local bend reflex consists of three layers of individually characterised neurons. While the population of mechanosensory cells provide multiplexed information about the stimulus, not much is known about how interneurons process this information. Here, we analyse the responses of two local bend interneurons (cell 157 and 159) to a mechanical stimulation of the skin and show their response characteristics to naturalistic stimuli. Intracellular dye-fills combined with structural imaging revealed that these interneurons are synaptically coupled to all three types of mechanosensory cells (T, P, and N cells). Since tactile stimulation of the skin evokes spikes in one to two cells of each of the latter types, interneurons combine inputs from up to six mechanosensory cells. We find that properties of touch location and intensity can be estimated reliably and accurately based on the graded interneuron responses. Connections to several mechanosensory cell types and specific response characteristics of the interneuron types indicate specialised filter and integration properties within this small neuronal network, thus providing evidence for more complex signal processing than previously thought. PMID- 29445204 TI - The effect of air pulse-driven whole eye motion on the association between corneal hysteresis and glaucomatous visual field progression. AB - Corneal hysteresis (CH) measured with Ocular Response Analyzer (Reichert: ORA) has been reported to be closely related to the glaucomatous visual field (VF) progression. The air pulse applied to an eye not only induces corneal deformation, but also whole eye motion (WEM), which may result in an inaccurate measurement of CH. Here we investigated the influence of air pulse-driven WEM measured with the Corivs ST (CST(r), OCULUS) on the relationship between CH and VF progression in primary open angle-glaucoma patients. Using the CST parameters of the maximal WEM displacement (WEM-d) and the time to reach that displacement (WEM-t), the eyes were classified into subgroups (WEM-d low- and high-group, and WEM-t short- and long-group). For the whole population and all subgroups, the optimal linear mixed model to describe mean of total deviation (mTD) progression rate with eight reliable VFs was selected from all combinations of seven parameters including CH. As a result, optimal models for the mTD progression rate included CH in the whole population, the WEM-d low- group and the WEM-t short group, but not in the WEM-d high-group and the WEM-t long-group. Our findings indicated association between CH and glaucomatous progression can be weakened because of large WEM. PMID- 29445205 TI - The plasmatic and salivary levels of IL-1beta, IL-18 and IL-6 are associated to emotional difference during stress in young male. AB - Saliva collection is considered a non-invasive method to detect inflammatory markers in response to emotional states within natural social contexts. Numerous studies have prompted an important role of cytokines in modulating distinct aspects of social and emotional behavior. The aim of this study was to investigate the reliability of plasma and saliva as investigative tools for measure some inflammatory marker levels (CRP, IL-1beta, IL-18, and IL-6). At the same time, the relationships between these markers and emotional states in response to a socio-cognitive stress (Academic Exam, AE), were considered. It was demonstrated that the plasma and saliva concentrations of all immune-mediators analyzed were significantly related across the socio-cognitive stress. In addition, when there was a close correlation to AE, the anger state, the IL 1beta, the IL-18 salivary and plasmatic concentrations were significantly higher, while they decreased during the AE. On the other hand, the anxiety state and the IL-6 levels significantly increased throughout the AE. The IL-1beta and IL-6 were positively associated to the anger and the anxiety state, respectively. In conclusion, our data highlight that different immune markers are similarly detectable in plasma and saliva during socio-cognitive stress. Also, they could be related to different emotional responses. PMID- 29445206 TI - Nanostructuring one-dimensional and amorphous lithium peroxide for high round trip efficiency in lithium-oxygen batteries. AB - The major challenge facing lithium-oxygen batteries is the insulating and bulk lithium peroxide discharge product, which causes sluggish decomposition and increasing overpotential during recharge. Here, we demonstrate an improved round trip efficiency of ~80% by means of a mesoporous carbon electrode, which directs the growth of one-dimensional and amorphous lithium peroxide. Morphologically, the one-dimensional nanostructures with small volume and high surface show improved charge transport and promote delithiation (lithium ion dissolution) during recharge and thus plays a critical role in the facile decomposition of lithium peroxide. Thermodynamically, density functional calculations reveal that disordered geometric arrangements of the surface atoms in the amorphous structure lead to weaker binding of the key reaction intermediate lithium superoxide, yielding smaller oxygen reduction and evolution overpotentials compared to the crystalline surface. This study suggests a strategy to enhance the decomposition rate of lithium peroxide by exploiting the size and shape of one-dimensional nanostructured lithium peroxide. PMID- 29445207 TI - Holographic Traction Force Microscopy. AB - Traction Force Microscopy (TFM) computes the forces exerted at the surface of an elastic material by measuring induced deformations in volume. It is used to determine the pattern of the adhesion forces exerted by cells or by cellular assemblies grown onto a soft deformable substrate. Typically, colloidal particles are dispersed in the substrate and their displacement is monitored by fluorescent microscopy. As with any other fluorescent techniques, the accuracy in measuring a particule's position is ultimately limited by the number of evaluated fluorescent photons. Here, we present a TFM technique based on the detection of probe particle displacements by holographic tracking microscopy. We show that nanometer scale resolutions of the particle displacements can be obtained and determine the maximum volume fraction of markers in the substrate. We demonstrate the feasibility of the technique experimentally and measure the three-dimensional force fields exerted by colorectal cancer cells cultivated onto a polyacrylamide gel substrate. PMID- 29445208 TI - Synergistic effect of nano-Pt and Ni spine for HER in alkaline solution: hydrogen spillover from nano-Pt to Ni spine. AB - The design of active, stable, and cost-effective electrocatalysts for the H2 evolution reaction (HER) in alkaline conditions is important for electrochemical systems such as the chloro-alkaline process and H2 production. Here we report catalysts comprising Pt on Ni single crystalline spines (Pt/Ni-SP) with high activity and stability for HER in alkaline solution with proposed mechanism. The Pt/Ni-SP catalysts are prepared by dispersing platinum nanoparticles (1.7-3.1 nm) on the single-crystalline spines (Ni-SP) of Ni urchin-like particles. The size and coverage of Pt nanoparticles on Ni-SP are increased with increases in the Pt loading amount. X-ray diffraction, high-resolution transmission electron microscopy, X-ray photoelectron spectroscopy, and X-ray absorption spectroscopy are performed to observe the structure of the Pt/Ni-SP catalyst. The catalysts achieve the mass activity of 1.11 A mg-1(Pt), comparing favorably to Pt/C catalysts with the mass activity of 0.33 A mg-1(Pt) at 0.05 V overpotential. The Tafel slope of the Pt/Ni-SP catalyst is approximately 30 mV dec-1, similar to that of Pt, while Pt/Ni-SP is very stable in alkaline solution, like Ni. The synergistic effect of Pt/Ni-SP is ascribed to H spillover from Pt to Ni. PMID- 29445210 TI - The Caveats of observing Inter-Trial Phase-Coherence in Cognitive Neuroscience. AB - Many studies have now consistently reported that the phase angle of ongoing oscillatory activity (measured using EEG/MEG), at time of stimulus presentation influences detection when stimuli are near-threshold. However, studies examining whether the adjustment of the phase angle of oscillations is under top-down attentional control have thus far yielded conflicting results. A possible source for the discrepancy could be that the estimation of the phase of ongoing oscillations as well as its uniformity across trials could be affected by task induced changes in the power of oscillations or concurrent evoked responses. One measure, Inter-Trial Phase-Locking (ITPC), or the uniformity of phase angles across trials, is particularly vulnerable to these factors. Here, using various simulations modelling the common task induced changes in the EEG reported in the literature, we demonstrate that apparent changes in Inter-Trial Phase-Locking of oscillatory activity can occur independent of any actual change in the phase of the ongoing activity. PMID- 29445209 TI - 3D microfluidic liver cultures as a physiological preclinical tool for hepatitis B virus infection. AB - With more than 240 million people infected, hepatitis B virus (HBV) is a major health concern. The inability to mimic the complexity of the liver using cell lines and regular primary human hepatocyte (PHH) cultures pose significant limitations for studying host/pathogen interactions. Here, we describe a 3D microfluidic PHH system permissive to HBV infection, which can be maintained for at least 40 days. This system enables the recapitulation of all steps of the HBV life cycle, including the replication of patient-derived HBV and the maintenance of HBV cccDNA. We show that innate immune and cytokine responses following infection with HBV mimic those observed in HBV-infected patients, thus allowing the dissection of pathways important for immune evasion and validation of biomarkers. Additionally, we demonstrate that the co-culture of PHH with other non-parenchymal cells enables the identification of the cellular origin of immune effectors, thus providing a valuable preclinical platform for HBV research. PMID- 29445211 TI - Bronchoscopic fibered confocal fluorescence microscopy for longitudinal in vivo assessment of pulmonary fungal infections in free-breathing mice. AB - Respiratory diseases, such as pulmonary infections, are an important cause of morbidity and mortality worldwide. Preclinical studies often require invasive techniques to evaluate the extent of infection. Fibered confocal fluorescence microscopy (FCFM) is an emerging optical imaging technique that allows for real time detection of fluorescently labeled cells within live animals, thereby bridging the gap between in vivo whole-body imaging methods and traditional histological examinations. Previously, the use of FCFM in preclinical lung research was limited to endpoint observations due to the invasive procedures required to access lungs. Here, we introduce a bronchoscopic FCFM approach that enabled in vivo visualization and morphological characterisation of fungal cells within lungs of mice suffering from pulmonary Aspergillus or Cryptococcus infections. The minimally invasive character of this approach allowed longitudinal monitoring of infection in free-breathing animals, thereby providing both visual and quantitative information on infection progression. Both the sensitivity and specificity of this technique were high during advanced stages of infection, allowing clear distinction between infected and non-infected animals. In conclusion, our study demonstrates the potential of this novel bronchoscopic FCFM approach to study pulmonary diseases, which can lead to novel insights in disease pathogenesis by allowing longitudinal in vivo microscopic examinations of the lungs. PMID- 29445212 TI - Archimedes' principle for characterisation of recombinant whole cell biocatalysts. AB - The ability of whole cells to catalyse multistep reactions, often yielding synthetically demanding compounds later used by industrial biotech or pharma, makes them an indispensable tool of synthetic chemistry. The complex reaction network employed by cellular catalysts and the still only moderate predictive power of modelling approaches leaves this tool challenging to engineer. Frequently, large libraries of semi-rationally generated variants are sampled in high-throughput mode in order to then identify improved catalysts. We present a method for space- and time-efficient processing of very large libraries (107) of recombinant cellular catalysts, in which the phenotypic characterisation and the isolation of positive variants for the entire library is done within one minute in a single, highly parallelized operation. Specifically, product formation in nanolitre-sized cultivation vessels is sensed and translated into the formation of catalase as a reporter protein. Exposure to hydrogen peroxide leads to oxygen gas formation and thus to a density shift of the cultivation vessel. Exploiting Archimedes' principle, this density shift and the resulting upward buoyancy force can be used for batch-wise library sampling. We demonstrate the potential of the method for both, screening and selection protocols, and envision a wide applicability of the system for biosensor-based assays. PMID- 29445213 TI - Wireless Data Transmission at Terahertz Carrier Waves Generated from a Hybrid InP Polymer Dual Tunable DBR Laser Photonic Integrated Circuit. AB - We report for the first time the successful wavelength stabilization of two hybrid integrated InP/Polymer DBR lasers through optical injection. The two InP/Polymer DBR lasers are integrated into a photonic integrated circuit, providing an ideal source for millimeter and Terahertz wave generation by optical heterodyne technique. These lasers offer the widest tuning range of the carrier wave demonstrated to date up into the Terahertz range, about 20 nm (2.5 THz) on a single photonic integrated circuit. We demonstrate the application of this source to generate a carrier wave at 330 GHz to establish a wireless data transmission link at a data rate up to 18 Gbit/s. Using a coherent detection scheme we increase the sensitivity by more than 10 dB over direct detection. PMID- 29445214 TI - RACK1 is indispensable for porcine reproductive and respiratory syndrome virus replication and NF-kappaB activation in Marc-145 cells. AB - Porcine reproductive and respiratory syndrome virus (PRRSV) causes porcine reproductive and respiratory syndrome (PRRS), which is currently insufficiently controlled. RACK1 (receptor of activated protein C kinase 1) was first identified as a receptor for protein kinase C, with increasing evidence showing that the functionally conserved RACK1 plays important roles in cancer development, NF kappaB activation and various virus infections. However, the roles of RACK1 during PRRSV infection in Marc-145 cells have not been described yet. Here we demonstrated that infection of Marc-145 cells with the highly pathogenic PRRSV strain YN-1 from our lab led to activation of NF-kappaB and upregulation of RACK1 expression. The siRNA knockdown of RACK1 inhibited PRRSV replication in Marc-145 cells, abrogated NF-kappaB activation induced by PRRSV infection and reduced the viral titer. Furthermore, knockdown of RACK1 could inhibit an ongoing PRRSV infection. We found that RACK1 is highly conserved across different species based on the phylogenetic analysis of mRNA and deduced amino acid sequences. Taken together, RACK1 plays an indispensable role for PRRSV replication in Marc-145 cells and NF-kappaB activation. The results would advance our further understanding of the molecular mechanisms underlying PRRSV infection in swine and indicate RACK1 as a promising potential therapeutic target. PMID- 29445215 TI - Origin, evolution, and distribution of the molecular machinery for biosynthesis of sialylated lipooligosaccharide structures in Campylobacter coli. AB - Campylobacter jejuni and Campylobacter coli are the most common cause of bacterial gastroenteritis worldwide. Additionally, C. jejuni is the most common bacterial etiological agent in the autoimmune Guillain-Barre syndrome (GBS). Ganglioside mimicry by C. jejuni lipooligosaccharide (LOS) is the triggering factor of the disease. LOS-associated genes involved in the synthesis and transfer of sialic acid (glycosyltranferases belonging to family GT-42) are essential in C. jejuni to synthesize ganglioside-like LOS. Despite being isolated from GBS patients, scarce genetic evidence supports C. coli role in the disease. In this study, through data mining and bioinformatics analysis, C. coli is shown to possess a larger GT-42 glycosyltransferase repertoire than C. jejuni. Although GT-42 glycosyltransferases are widely distributed in C. coli population, only a fraction of C. coli strains (1%) are very likely able to express ganglioside mimics. Even though the activity of C. coli specific GT-42 enzymes and their role in shaping the bacterial population are yet to be explored, evidence presented herein suggest that loss of function of some LOS-associated genes occurred during agriculture niche adaptation. PMID- 29445216 TI - Evaluation of HER2-specific peptide ligand for its employment as radiolabeled imaging probe. AB - HER2 transmembrane receptor is an important target in immunotherapy treatment of breast and gastroesophageal cancer. Molecular imaging of HER2 expression may provide essential prognostic and predictive information concerning disseminated cancer and aid in selection of an optimal therapy. Radiolabeled low molecular weight peptide ligands are particularly attractive as probes for molecular imaging, since they reach and bind to the target and clear from non-target organs and blood stream faster than bulky antibodies. In this study, we evaluated a potential HER2-imaging probe, an A9 nonapeptide, derived from the trastuzumab-Fab portion. Its cellular uptake was investigated by mass spectrometry analysis of the cytoplasmic cellular extracts. Moreover, based on in-silico modeling, DTPA chelator was conjugated to N-terminus of A9. 111In-labeled A9 demonstrated nanomolar affinity to HER2-expressing BT474 cells and favorable biodistribution profile in NMRI mice. This study suggests that the peptide A9 represents a good lead candidate for development of molecular probe, to be used for imaging purposes and for the delivery of cytotoxic agents.

AB - In noncentrosymmetric crystals with broken inversion symmetry [Formula: see text], the I-V (I: current, V: voltage) characteristic is generally expected to depend on the direction of I, which is known as nonreciprocal response and, for example, found in p-n junction. However, it is a highly nontrivial issue in translationally invariant systems since the time-reversal symmetry T plays an essential role, where the two states at crystal momenta k and -k are connected in the band structure. Therefore, it has been considered that the external magnetic field (B) or the magnetic order which breaks the T-symmetry is necessary to realize the nonreciprocal I-V characteristics, i.e., magnetochiral anisotropy. Here we theoretically show that the electron correlation in T-broken multi-band systems can induce nonreciprocal I-V characteristics without T-breaking. An analog of Onsager's relation shows that nonreciprocal current response without T breaking generally requires two effects: dissipation and interactions. By using nonequilibrium Green's functions, we derive general formula of the nonreciprocal response for two-band systems with onsite interaction. The formula is applied to Rice-Mele model, a representative 1D model with inversion breaking, and some candidate materials are discussed. This finding offers a coherent understanding of the origin of nonreciprocal I-V characteristics, and will pave a way to design it.

AB - A thorough understanding of starch gelatinization is needed to control starch functional properties for food processing and human nutrition. Here, we reveal the mechanism of structural disassembly of rice, maize and wheat starch granules during thermal transitions in which a Rapid Visco Analyzer (RVA) was used to pre heat the starches to certain transition points in the differential scanning calorimetry (DSC) heating profiles. This was done to generate sufficient material for structural analyses. The results from DSC, Raman, X-ray diffraction and scanning electron microscopy (SEM) analyses all showed that at the conclusion temperature (Tc) of the DSC endotherm rice starch gelatinization was complete, whereas residual structural order remained in maize and wheat starches. Gelatinization of wheat and maize starch was complete at a temperature higher than Tc in the profile, which we define as the end temperature (Te). We propose that Te would be better to define the completion point of starch gelatinization than Tc. PMID- 29445219 TI - Comparative toxicity of five dispersants to coral larvae. AB - Oil spill responders require information on the absolute and relative toxicities of chemical dispersants to relevant receptor species to assess their use in spill response. However, little toxicity data are available for tropical marine species including reef-building corals. In this study, we experimentally assessed the sub lethal toxicity of five dispersants to larvae of the coral Acropora millepora over three short exposure periods (2, 6 and 24 h) reflecting real-world spill response scenario durations. Inhibition of larval settlement increased rapidly between 2 and 6 h, and was highest at 24 h: EC50 Corexit EC9500A = 4.0 mg l-1; Ardrox 6120 = 4.0 mg l-1; Slickgone LTSW = 2.6 mg L-1; Slickgone NS = 11.1 mg L-1 and Finasol OSR52 = 3.4 mg L-1. Coral larvae were more sensitive to dispersants than most other coral life stages and marine taxa, but the toxic thresholds (EC10s) exceeded most realistic environmental dispersant concentrations. Estimating toxic threshold values for effects of dispersants on coral should benefit the decision-making of oil spill responders by contributing to the development of species sensitivity distributions (SSDs) for dispersant toxicity, and by informing net environmental benefit assessment (NEBA) for dispersant use. PMID- 29445220 TI - Association of admission serum levels of vitamin D, calcium, Phosphate, magnesium and parathormone with clinical outcomes in neurosurgical ICU patients. AB - To evaluate the association of admission serum levels of 25(OH)D, parathormone and the related electrolytes with severity of illness and clinical outcomes in neurosurgical critically ill patients, serum levels of 25(OH)D, parathormone, calcium, magnesium, and phosphate, along with APACHE II score were measured for 210 patients upon admission. Mean serum 25(OH)D was 21.1 +/- 7.4 ng/mL. 25(OH)D deficiency (less than 20 ng/dL) and elevated serum parathormone level were found in 47.6% and 38% of patients respectively. Hypocalcaemia, hypophosphatemia, hypomagnesaemia and hypermagnesaemia were found in 29.5%, %63.8, 41.9% and 27.6% of patients respectively. The APACHE II score was significantly correlated with serum levels of 25(OH)D, parathormone, calcium, and phosphate. Multivariate regression analysis adjusted by other risk factors showed that among all clinical outcomes, admission hypovitaminosis D was associated with longer duration of ICU stay and a high admission of parathormone was associated with in ICU mortality. We concluded that disorders of admission serum levels of 25(OH)D, parathormone, calcium, magnesium, and phosphate are related to the presence of multiple causal factors such as severity of disease and are not independently associated with clinical outcomes. Most often they are normalize spontaneously with resolution of the disease process. PMID- 29445221 TI - Remodeling of the Actin/Spectrin Membrane-associated Periodic Skeleton, Growth Cone Collapse and F-Actin Decrease during Axonal Degeneration. AB - Axonal degeneration occurs in the developing nervous system for the appropriate establishment of mature circuits, and is also a hallmark of diverse neurodegenerative diseases. Despite recent interest in the field, little is known about the changes (and possible role) of the cytoskeleton during axonal degeneration. We studied the actin cytoskeleton in an in vitro model of developmental pruning induced by trophic factor withdrawal (TFW). We found that F actin decrease and growth cone collapse (GCC) occur early after TFW; however, treatments that prevent axonal fragmentation failed to prevent GCC, suggesting independent pathways. Using super-resolution (STED) microscopy we found that the axonal actin/spectrin membrane-associated periodic skeleton (MPS) abundance and organization drop shortly after deprivation, remaining low until fragmentation. Fragmented axons lack MPS (while maintaining microtubules) and acute pharmacological treatments that stabilize actin filaments prevent MPS loss and protect from axonal fragmentation, suggesting that MPS destruction is required for axon fragmentation to proceed.

AB - The dynamic motion of a water droplet on an inclined hydrophobic surface is analyzed with and without environmental dust particles on the surface. Solution crystallization of a polycarbonate surface is carried out to generate a hydrophobic surface with hierarchical texture composed of micro/nanosize spheroids and fibrils. Functionalized nanosize silica particles are deposited on the textured surface to reduce contact angle hysteresis. Environmental dust particles are collected and characterized using analytical tools prior to the experiments. The droplet motion on the hydrophobic surface is assessed using high speed camera data, and then, the motion characteristics are compared with the corresponding analytical results. The influence of dust particles on the water droplet motion and the amount of dust particles picked up from the hydrophobic surface by the moving droplet is evaluated experimentally. A 40 MUL droplet was observed to roll on the hydrophobic surface with and without dust particles, and the droplet slip velocity was lower than the rotational velocity. The rolling droplet removes almost all dust particles from the surface, and the mechanism for the removal of dust particles from the surface was determined to be water cloaking of the dust particles. PMID- 29445223 TI - Thermodynamically induced in Situ and Tunable Cu Plasmonic Behaviour. AB - The Cu nanoparticles (Cu NPs) were grown in soda-lime glass matrix through Cu+ < > Na+ ion exchange methods under thermal annealing in an open environment and studied variation in their size on tunable plasmonic behaviour, optical absorption spectra and photoluminescence (PL). A blue shift from 570 to 560 nm was observed in localized surface plasmon resonance (SPR) of Cu NPs from 550 to 650 degrees C. A mutual relation between size and surface plasmon resonance with full width half maxima (FWHM) has been derived for plasmonic properties at variable temperatures. Structural investigations of embedded Cu NPs have been confirmed by using HRTEM and EDX. Grazing incidence X-ray diffraction (GIXRD) had identified a crystalline nature of Cu NPs under annealed conditions. XPS, Raman and secondary ion mass spectroscopies (SIMS) have identified an embedding behaviour of Cu NPs in glass matrix. Plasmonic and thermodynamic properties of embedded Cu NPs have explained their in situ thermal growth mechanism for efficient distribution where enthalpy (?H), entropy (?S) and Gibbs free energy (?G) have interpreted their temperature driven Cu NPs growth. An interdependence of ?H, ?S and ?G has been developed vis-a-vis activation energy on an extent of 12.54 J/mol.

AB - Betulin (BT), a pentacyclic lupine-type triterpenoid natural product, possesses antitumor activity in various types of cancers. However, its clinical development was discouraged due to its low biological activities and poor solubility. We prepared lup-20(29)-en-3beta,28-di-yl-nitrooxy acetate (NBT), a derivative of BT, that was chemically modified at position 3 of ring A and C-28 by introducing a NO releasing moiety. This study mainly explored the mechanism of NBT in treating breast cancer through the crosstalk between apoptosis and autophagy in mitochondria. NBT possessed a potent antiproliferative activity in MCF-7 cells both in vitro and in vivo. Mechanically, NBT affected cell death through the mitochondrial apoptosis pathway and autophagy. NBT induced cell cycle arrest in the G0/G1 phase by decreasing the expression of cyclin D1. It also induced mitochondrial apoptosis by increasing the expression of Bax, caspase-9, and poly(ADP-ribose) polymerase and mitochondrial membrane potential loss and leaks of cytochrome c (Cyt C) from mitochondria in MCF-7 cells and decreasing the expression of mitochondrial Bcl-2. We further demonstrated whether chloroquine (CQ), which inhibits the degradation of autophagosome induced by NBT, affects the proliferation of MCF-7 cells compared with NBT. The experiments inferred that the combination of NBT and CQ significantly promoted MCF-7 cell mitochondria to divide and Cyt C to be released from mitochondria to the cytoplasm, resulting in an increased apoptosis rate. The in vivo experiments showed that NBT inhibited the growth of MCF-7 tumor via the apoptosis pathway, and its effect was similar to 5-fluorouracil. PMID- 29445225 TI - Atrial Fibrillation Characteristics in Patients on Haemodialysis vs. Peritoneal Dialysis. AB - Atrial fibrillation (AF) is highly prevalent in dialysis patients, however whether its impact differs between patients on haemodialysis (HD) vs. peritoneal dialysis (PD) is unknown. We aimed to compare the association of AF and clinical outcomes in different dialysis modalities. We performed a population based retrospective cohort study, including adult patients who initiated dialysis between the years 2002 and 2015. Clinical, echocardiographic and laboratory data were reviewed and correlated with outcomes in HD vs. PD. During the study period, 1,130 patients began dialysis. Of the 997 patients without AF before dialysis initiation, 17% developed new-onset AF after the initiation of dialysis (17.3% of HD vs. 13.7% of PD patients, p = 0.27). Using multivariate analysis, only enlarged left atrium at dialysis initiation (hazard ratio (HR) 2.82, CI95% 2.00 3.99) and age (HR 1.04, CI95% 1.03-1.06) were significantly associated with AF. Dialysis modality was not a significant predictor of AF in either univariate or multivariate analysis. In conclusion, our study demonstrated that AF is common in dialysis patients irrespective of modality. In our cohort, the risk factors associated with AF were older age and enlarged left atrium. AF was associated with increased rates of heart failure and mortality, but not stroke. PMID- 29445226 TI - GCY-35/GCY-36-TAX-2/TAX-4 Signalling in O2 Sensory Neurons Mediates Acute Functional Ethanol Tolerance in Caenorhabditis elegans. AB - Ethanol is a widely used beverage and abused drug. Alcoholism causes severe damage to human health and creates serious social problems. Understanding the mechanisms underlying ethanol actions is important for the development of effective therapies. Alcohol has a wide spectrum of effects on physiological activities and behaviours, from sensitization to sedation and even intoxication with increasing concentrations. Animals develop tolerance to ethanol. However, the underlying mechanisms are not well understood. In Caenorhabditis elegans, NPR 1 negatively regulates the development of acute tolerance to ethanol. Here, using in vivo Ca2+ imaging, behavioural tests and chemogenetic manipulation, we show that the soluble guanylate cyclase complex GCY-35/GCY-36-TAX-2/TAX-4 signalling pathway in O2 sensory neurons positively regulates acute functional tolerance in npr-1 worms. PMID- 29445227 TI - Novel ubiquitin-independent nucleolar c-Myc degradation pathway mediated by antizyme 2. AB - The proto-oncogene c-Myc encodes a short-lived protein c-Myc that regulates various cellular processes including cell growth, differentiation and apoptosis. Degradation of c-Myc is catalyzed by the proteasome and requires phosphorylation of Thr-58 for ubiquitination by E3 ubiquitin ligase, Fbxw7/ FBW7. Here we show that a polyamine regulatory protein, antizyme 2 (AZ2), interacts with c-Myc in the nucleus and nucleolus, to accelerate proteasome-mediated c-Myc degradation without ubiquitination or Thr-58 phosphorylation. Polyamines, the inducer of AZ2, also destabilize c-Myc in an AZ2-dependent manner. Knockdown of AZ2 by small interfering RNA (siRNA) increases nucleolar c-Myc and also cellular pre-rRNA whose synthesis is promoted by c-Myc. AZ2-dependent c-Myc degradation likely operates under specific conditions such as glucose deprivation or hypoxia. These findings reveal the targeting mechanism for nucleolar ubiquitin-independent c-Myc degradation. PMID- 29445228 TI - A Study on Curing Kinetics of Nano-Phase Modified Epoxy Resin. AB - In this paper, DSC curves at different heating rates were measured by DSC, the characteristic curing temperature was determined, and the optimum curing conditions were obtained. The KAS method, Friedman method and FWO method were used to analyze the DSC curves respectively. The kinetic parameters and the reaction mechanism function of the curing system were obtained, and the results of different analytical methods were compared and analyzed. Result from fitting and verification of the curing kinetic model for the curing system of the nano phase modified epoxy resin further demonstrates that the nano-particle could play a catalytic role in the curing reaction of the epoxy resin and could reduce the apparent activation energy of the system, thus it is considered as a breakthrough in the field of resin research. PMID- 29445229 TI - Enhanced Electrochemical Properties of Zr4+-doped Li1.20[Mn0.52Ni0.20Co0.08]O2 Cathode Material for Lithium-ion Battery at Elevated Temperature. AB - The typical co-precipitation method was adopted to synthesized the Li-excess Li1.20[Mn0.52-xZr x Ni0.20Co0.08]O2 (x = 0, 0.01, 0.02, 0.03) series cathode materials. The influences of Zr4+ doping modification on the microstructure and micromorphology of Li1.20[Mn0.52Ni0.20Co0.08]O2 cathode materials were studied intensively by the combinations of XRD, SEM, LPS and XPS. Besides, after the doping modification with zirconium ions, Li1.20[Mn0.52Ni0.20Co0.08]O2 cathode demonstrated the lower cation mixing, superior cycling performance and higher rate capacities. Among the four cathode materials, the Li1.20[Mn0.50Zr0.02Ni0.20Co0.08]O2 exhibited the prime electrochemical properties with a capacity retention of 88.7% (201.0 mAh g-1) after 100 cycles at 45 degrees C and a discharge capacity of 114.7 mAh g-1 at 2 C rate. The EIS results showed that the Zr4+ doping modification can relieve the thickening of SEI films on the surface of cathode and accelerate the Li+ diffusion rate during the charge and discharge process. PMID- 29445230 TI - Investigation of biomarkers alterations after an acute tissue trauma in human trapezius muscle, using microdialysis. AB - Alterations in muscle milieu are suggested as important activity of peripheral drive in patients with chronic musculoskeletal pain (CMP). Microdialysis (MD) has been used in monitoring altered metabolic response pattern in muscles. However, the insertion of MD probe causes a local tissue trauma. Whether and how metabolites in trapezius muscle are affected by acute tissue trauma is unknown. Hence, this study investigated the metabolic response and nociceptive reaction of the tissue following MD probe insertion in patients with CMP and healthy individuals. Fifty-nine patients and forty pain-free volunteers were recruited. Pressure pain thresholds (PPTs) were obtained at the trapezius and tibialis muscles. Pain questionnaires determined the levels of pain related aspects. MD (20 kDa cut-off) was performed in the trapezius and samples were collected within 40 min. Interstitial concentration of the metabolites was analyzed by a two-way mixed-ANOVA. The metabolic response pattern changed over time and alterations in the level of metabolites could be seen in both CMP and healthy controls. Pain questionnaires and pain intensities manifested clinical aspects of pain closely to what CMP patients describe. Analyzing metabolites due to acute tissue trauma by aid of MD may be a useful model to investigate altered metabolic response effect in CMP. PMID- 29445231 TI - Impact of nanoparticles on the Bacillus subtilis (3610) competence. AB - Due to the physicochemical properties of nanoparticles, the use of nanomaterials increases every year in industrial and medical processes. At the same time, the increasing number of bacteria becoming resistant to many antibiotics, mostly by a horizontal gene transfer process, is a major public health concern. We herein report, for the first time, the role of nanoparticles in the physiological induction of horizontal gene transfer in bacteria. Besides the most well-known impacts of nanoparticles on bacteria, i.e. death or oxidative stress, two nanoparticles, n-ZnO and n-TiO2, significantly and oppositely impact the transformation efficiency of Bacillus subtilis in biofilm growth conditions, by modification of the physiological processes involved in the induction of competence, the first step of transformation. This effect is the consequence of a physiological adaptation rather than a physical cell injury: two oligopeptide ABC transporters, OppABCDF and AppDFABC, are differentially expressed in response to nanoparticles. Interestingly, a third tested nanoparticle, n-Ag, has no significant effect on competence in our experimental conditions. Overall, these results show that nanoparticles, by altering bacterial physiology and especially competence, may have profound influences in unsuspected areas, such as the dissemination of antibiotic resistance in bacteria. PMID- 29445232 TI - The Cerebellum of Patients with Steatohepatitis Shows Lymphocyte Infiltration, Microglial Activation and Loss of Purkinje and Granular Neurons. AB - Peripheral inflammation contributes to minimal hepatic encephalopathy in chronic liver diseases, which could be mediated by neuroinflammation. Neuroinflammation in cerebellum of patients with chronic liver diseases has not been studied in detail. Our aim was to analyze in cerebellum of patients with different grades of liver disease, from mild steatohepatitis to cirrhosis and hepatic encephalopathy: (a) neuronal density in Purkinje and granular layers; (b) microglial activation; (c) astrocyte activation; (d) peripheral lymphocytes infiltration; (e) subtypes of lymphocytes infiltrated. Steatohepatitis was classified as SH1, SH2 and SH3. Patients with SH1 show Th17 and Tfh lymphocytes infiltration in the meninges, microglia activation in the molecular layer and loss of 16 +/- 4% of Purkinje and 19 +/- 2% of granular neurons. White matter remains unaffected. With the progression of liver disease to worse stages (SH2, SH3, cirrhosis) activation of microglia and astrocytes extends to white matter, Bergman glia is damaged in the molecular layer and there is a further loss of Purkinje neurons. The results reported show that neuroinflammation in cerebellum occurs at early stages of liver disease, even before reaching cirrhosis. Neuroinflammation occurs earlier in the molecular layer than in white matter, and is associated with infiltration of peripheral Th17 and Tfh lymphocytes. PMID- 29445233 TI - In vitro cytotoxicity activity of novel Schiff base ligand-lanthanide complexes. AB - A Schiff base ligand (SBL), N2, N3-bis (anthracen-9-ylmethylene) pyridine-2, 3 diamine, was synthesized through the condensation of 2,6-diaminopyridine and anthracene-9-carbaldehyde using a 1:2 ratio. 1H NMR spectra confirmed the observation of non-involvement aromatic carboxylic proton in SBL. A novel series of lanthanide (i.e., praseodymium (Pr), erbium (Er), and ytterbium (Yb))-based SBL metal complexes was successfully synthesized, and their functional groups were elaborately demonstrated using UV-visible, Fourier transform infrared (FT IR), and fluorescence spectroscopy analyses. FT-IR spectral studies revealed that SBL behaved as a bidentate ligand and it was structured with metal ions by the two azomethine nitrogens. The synthesized SBL-based metal complexes were elaborately performed for cytotoxicity activity versus Vero, human breast cancer (MCF7), and cervical (HeLa) anticancer cell lines. PMID- 29445234 TI - Tuning the Optical Properties of Silicon Quantum Dots via Surface Functionalization with Conjugated Aromatic Fluorophores. AB - Silicon Quantum Dots (SQDs) have recently attracted great interest due to their excellent optical properties, low cytotoxicity, and ease of surface modification. The size of SQDs and type of ligand on their surface has a great influence on their optical properties which is still poorly understood. Here we report the synthesis and spectroscopic studies of three families of unreported SQDs functionalized by covalently linking to the aromatic fluorophores, 9 vinylphenanthrene, 1-vinylpyrene, and 3-vinylperylene. The results showed that the prepared functionalized SQDs had a highly-controlled diameter by HR-TEM, ranging from 1.7-2.1 nm. The photophysical measurements of the assemblies provided clear evidence for efficient energy transfer from the fluorophore to the SQD core. Forster energy transfer is the likely mechanism in these assemblies. As a result of the photogenerated energy transfer process, the emission color of the SQD core could be efficiently tuned and its emission quantum efficiency enhanced. To demonstrate the potential application of the synthesized SQDs for bioimaging of cancer cells, the water-soluble perylene- and pyrene-capped SQDs were examined for fluorescent imaging of HeLa cells. The SQDs were shown to be of low cytotoxicity. PMID- 29445235 TI - Development and application of a rapid Mycobacterium tuberculosis detection technique using polymerase spiral reaction. AB - Mycobacterium tuberculosis is an age-old bacterium that is difficult to eliminate. A simple and rapid diagnostic method is of great importance to prevent the spread of M. tuberculosis. Here, we developed a low-cost rapid M. tuberculosis nucleic acid detection technique, named GenePop, which enabled the storage and transport of M. tuberculosis diagnostic reagent at ambient temperatures, without the need for professional operations or expensive instrumentation. Using a vitrification method, we vitrified heat-unstable components onto the cap of a reaction tube, and placed heat-stable components at the bottom of the reaction tube by sealing them with paraffin wax. The all-in-one detection tube, when used together with our other invention-a multi-functional sample treatment tube pre-filled with a nucleic acid-releasing agent-only required three simple steps to yield results. A comparative analysis with a commercial qPCR kit for M. tuberculosis indicated that our new technique had a concordance rate of 91.6%, showing no cross-reactivity with 11 other bacteria. The complete operation time was only 65 min. It is suitable for use in field settings or by personnel in grass-root units, and is applicable in household activities, hence can be used in developing countries. PMID- 29445237 TI - Comparing watershed afforestation and natural revegetation impacts on soil moisture in the semiarid Loess Plateau of China. AB - Two contiguous watersheds in the Loess Plateau in China that differed in the way their vegetation had been restored-afforestation or natural revegetation-differed in their consumption of soil moisture: the afforested watershed consumed more soil moisture, although the difference was significant only in wet years. Yet, both the afforestation and natural revegetation did not induce the soil desiccation in the study area. In the afforested watershed, soil moisture was depleted even beyond a depth of 100 cm, whereas in the grassland (natural revegetation), the depletion was confined to a layer less than 60 cm deep. Rainfall in the growing season accounted for 46-60% of the variation in soil moisture in the 0-60 cm layer in the grassland, but only 22-39% of that in the forest land. Overall, afforestation is the better option for the Loess Plateau only in areas where the annual rainfall is more than 500 mm. In any attempt at revegetation, the choice of tree species and planting densities should match the carrying capacity of the region's water resources. PMID- 29445236 TI - Retinotopic effects of visual attention revealed by dichoptic multifocal pupillography. AB - Multifocal pupillographic objective perimetry (mfPOP) has recently been shown to be able to measure cortical function. Here we assessed 44 regions of the central 60 degrees of the visual fields of each eye concurrently in 7 minutes/test. We examined how foveally- and peripherally-directed attention changed response sensitivity and delay across the 44 visual field locations/eye. Four experiments were completed comparing white, yellow and blue stimulus arrays. Experiments 1 to 4 tested 16, 23, 9 and 6 subjects, 49/54 being unique. Experiment 1, Experiments 2 and 3, and Experiment 4 used three variants of the mfPOP method that provided increasingly improved signal quality. Experiments 1 to 3 examined centrally directed attention, and Experiment 4 compared effects of attention directed to different peripheral targets. Attention reduced the sensitivity of the peripheral locations in Experiment 1, but only for the white stimuli not yellow. Experiment 2 confirmed that result. Experiment 3 showed that blue stimuli behaved like white. Peripheral attention showed increased sensitivity around the attentional targets. The results are discussed in terms of the cortical inputs to the pupillary system. The results agree with those from multifocal and other fMRI and VEP studies. mfPOP may be a useful adjunct to those methods. PMID- 29445238 TI - VPS35 depletion does not impair presynaptic structure and function. AB - The endosomal system is proposed as a mediator of synaptic vesicle recycling, but the molecular recycling mechanism remains largely unknown. Retromer is a key protein complex which mediates endosomal recycling in eukaryotic cells, including neurons. Retromer is important for brain function and mutations in retromer genes are linked to neurodegenerative diseases. In this study, we aimed to determine the role of retromer in presynaptic structure and function. We assessed the role of retromer by knocking down VPS35, the core subunit of retromer, in primary hippocampal mouse neurons. VPS35 depletion led to retromer dysfunction, measured as a decrease in GluA1 at the plasma membrane, and bypassed morphological defects previously described in chronic retromer depletion models. We found that retromer is localized at the mammalian presynaptic terminal. However, VPS35 depletion did not alter the presynaptic ultrastructure, synaptic vesicle release or retrieval. Hence, we conclude that retromer is present in the presynaptic terminal but it is not essential for the synaptic vesicle cycle. Nonetheless, the presynaptic localization of VPS35 suggests that retromer-dependent endosome sorting could take place for other presynaptic cargo. PMID- 29445240 TI - High fat diet-induced metabolically obese and normal weight rabbit model shows early vascular dysfunction: mechanisms involved. AB - BACKGROUND: Obesity contributes significantly to the development and evolution of cardiovascular disease (CVD) which is believed to be mediated by oxidative stress, inflammation and endothelial dysfunction. However, the vascular health of metabolically obese and normal weight (MONW) individuals is not completely comprehended. OBJECTIVES: The purpose of our study was to evaluate vascular function on the basis of a high fat diet (HFD)-MONW rabbit model. SUBJECTS: Twenty four male rabbits were randomly assigned to receive either a regular diet (CD, n = 12) or a high-fat diet (18% extra fat on the regular diet, HFD, n = 12) for 6 weeks. RESULTS: Body weight, TBARS and gluthathione serum levels were similar between the groups; fasting glucose, triglycerides, C reactive protein (CRP), visceral adipose tissue (VAT), triglyceride-glucose index (TyG index) were higher in the HFD group. Compared to CD, the HFD rabbits had glucose intolerance and lower HDL-cholesterol and plasma nitrites levels. Thoracic aortic rings from HFD rabbits exhibited: (a) a reduced acetylcholine-induced vasorelaxation; (b) a greater contractile response to norepinephrine and KCl; (c) an improved angiotensin II-sensibility. The HFD-effect on acetylcholine-response was reversed by the cyclooxygenase-2 (COX-2) inhibitor (NS398) and the cyclooxygenase-1 inhibitor (SC560), and the HFD-effect on angiotensin II was reversed by NS398 and the TP receptor blocker (SQ29538). Immunohistochemistry and western blot studies showed COX-2 expression only in arteries from HFD rabbits. CONCLUSIONS: Our study shows a positive pro-inflammatory status of HFD-induced MONW characterized by raised COX-2 expression, increase of the CRP levels, reduction of NO release and oxidative stress-controlled conditions in an early stage of metabolic alterations characteristic of metabolic syndrome. Endothelial dysfunction and increased vascular reactivity in MONW individuals may be biomarkers of early vascular injury. Therefore, the metabolic changes induced by HFD even in normal weight individuals may be associated to functional alterations of blood vessels. PMID- 29445239 TI - The Urokinase Receptor Induces a Mesenchymal Gene Expression Signature in Glioblastoma Cells and Promotes Tumor Cell Survival in Neurospheres. AB - PLAUR encodes the urokinase receptor (uPAR), which promotes cell survival, migration, and resistance to targeted cancer therapeutics in glioblastoma cells in culture and in mouse model systems. Herein, we show that patient survival correlates inversely with PLAUR mRNA expression in gliomas of all grades, in glioblastomas, and in the subset of glioblastomas that demonstrate the mesenchymal gene expression signature. PLAUR clusters with genes that define the more aggressive mesenchymal subtype in transcriptome profiles of glioblastoma tissue and glioblastoma cells in neurospheres, which are enriched for multipotent cells with stem cell-like qualities. When PLAUR was over-expressed or silenced in glioblastoma cells, neurosphere growth and expression of mesenchymal subtype biomarkers correlated with uPAR abundance. uPAR also promoted glioblastoma cell survival in neurospheres. Constitutively-active EGF Receptor (EGFRvIII) promoted neurosphere growth; however, unlike uPAR, EGFRvIII did not induce the mesenchymal gene expression signature. Immunohistochemical analysis of human glioblastomas showed that uPAR is typically expressed by a small sub-population of the cancer cells; it is thus reasonable to conclude that this subpopulation of cells is responsible for the effects of PLAUR on patient survival. We propose that uPAR expressing glioblastoma cells demonstrate a mesenchymal gene signature, an increased capacity for cell survival, and stem cell-like properties. PMID- 29445241 TI - Is early life exposure to polyomaviruses and herpesviruses associated with obesity indices and metabolic traits in childhood? AB - BACKGROUND: Evidence for an infectious origin of obesity is emerging. We explored whether common viruses were associated with obesity and metabolic traits. METHODS: We used cross-sectional (n = 674) and prospective (n = 440) data from children participating at the 4 and 6 years of age follow-up in the Rhea birth cohort. Presence of IgG antibodies to ten polyomaviruses (BKPyV, JCPyV, KIPyV, WUPyV, HPyV6, HPyV7, TSPyV, MCPyV, HPyV9, and HPyV10) and four herpesviruses (EBV, CMV, HSV-1, and HSV-2) were measured at age 4. Body mass index, waist circumference, and skinfold thickness were measured at age 4 and 6. Data on serum lipids, leptin, and adiponectin were also available. Multivariable linear regression models were used to explore the associations. RESULTS: At 4 years of age, seroprevalence to polyomaviruses ranged from 21.0% for HPyV9 to 82.0% for HPyV10. Seroprevalence for EBV, CMV, HSV-1, and HSV-2 was 53.0%, 26.0%, 3.6%, and 1.5% respectively. BKPyV seropositivity was associated with lower BMI SD score at age 4 [-0.21 (95% CI: -0.39, -0.03)] and 6 [-0.27 (95% CI:-0.48, -0.05)], waist circumference at age 4 [-1.12 cm (95% CI: -2.10, -0.15)] and 6 [-1.73 cm (95% CI: -3.33, -0.12)], sum of four skinfolds [-2.97 mm (95% CI: -5.70, -0.24)], and leptin levels at age 4 [ratio of geometric means, 0.83 (95% CI: 0.70, 0.98)]. CMV seropositivity was associated with higher BMI SD score at age 4 [0.28 (95% CI: 0.11, 0.45)] and 6 [0.24 (95% CI: 0.03, 0.45)] and sum of four skinfolds at age 6 [4.75 mm (95% CI: 0.67, 8.83)]. Having "2-3 herpesviruses infections" (versus "0 herpesvirus infections") was associated with higher BMI SD score [0.32, (95% CI: 0.12, 0.53)], waist circumference [1.22 cm (95% CI: 0.13, 2.31)], and sum of four skinfolds [3.26 mm (95% CI: 0.18, 6.35)] at age 4. Polyomaviruses burden was not associated with outcomes. CONCLUSIONS: A higher herpesviruses burden and CMV seropositivity were associated with obesity traits in childhood.

AB - Previously reported co-occurrence of colorectal cancer (CRC) and tooth agenesis (TA) and the overlap in disease-associated gene variants suggest involvement of similar molecular pathways. Here, we took an unbiased approach and tested genome wide significant CRC-associated variants for association with isolated TA. Thirty single nucleotide variants (SNVs) in CRC-predisposing genes/loci were genotyped in a discovery dataset composed of 440 individuals with and without isolated TA. Genome-wide significant associations were found between TA and ATF1 rs11169552 (P = 4.36 * 10-10) and DUSP10 rs6687758 (P = 1.25 * 10-9), and positive association found with CASC8 rs10505477 (P = 8.2 * 10-5). Additional CRC marker haplotypes were also significantly associated with TA. Genotyping an independent dataset consisting of 52 cases with TA and 427 controls confirmed the association with CASC8. Atf1 and Dusp10 expression was detected in the mouse developing teeth from early bud stages to the formation of the complete tooth, suggesting a potential role for these genes and their encoded proteins in tooth development. While their individual contributions in tooth development remain to be elucidated, these genes may be considered candidates to be tested in additional populations. PMID- 29445243 TI - Quantitative assessment of liver fibrosis (qFibrosis) reveals precise outcomes in Ishak "stable" patients on anti-HBV therapy. AB - Current widely used semiquantitative histological assessment methods are insensitive to identify subtle changes of liver fibrosis. Therefore, to precisely assess therapeutic efficacy on chronic hepatitis B (CHB), we explored the utility of qFibrosis (a fully-quantitative morphometric method employing second harmonic generation/two photon excitation fluorescence) in liver fibrosis evaluation. Fibrosis changes were evaluated by Ishak fibrosis scoring and qFibrosis in CHB patients with paired liver biopsies before and after 78 weeks' antiviral therapy. A total of 162 patients with qualified paired biopsies were enrolled. Ishak fibrosis scoring revealed that 42.6% (69/162) of the patients achieved fibrosis regression (>=1-point decrease), 51.9% (84/162) remained stable, and 5.5% (9/162) showed progression (>=1-point increase). qFibrosis showed similar trends in the groups of regression and progression patients as evaluated by Ishak. However, in Ishak stable patients, qFibrosis revealed hitherto undetected changes, allowing for further subcategorization into regression ("Regression by qFibrosis"; 40/84, 47.6%), stable (29/84, 34.5%), and progression ("Progression by qFibrosis"; 15/84, 17.9%) groups. These newly fine-tuned categories were supported by changes of morphological parameters of fibrosis, collagen percentage area, and liver stiffness measurements. In conclusion, qFibrosis can be used to quantitatively identify subtle changes of liver fibrosis in CHB patients after antiviral therapy.

The structural origin of ammonia selectivity remains obscure, but experiments have revealed that a double mutation renders it impermeable to ammonia without affecting water permeability. Here, we aim to reproduce and explain these observations by performing an extensive mutational study using microsecond long molecular dynamics simulations, applying the two popular force fields CHARMM36 and Amber ff99SB-ILDN. We calculate permeabilities and free energies along the channel axis for ammonia and water. For one force field, the permeability of the double mutant decreases by a factor of 2.5 for water and 4 for ammonia, increasing water selectivity by a factor of 1.6. We attribute this effect to decreased entropy of water in the pore, due to the observed increase in pore water interactions and narrower pore. Additionally, we observe spontaneous opening and closing of the pore on the cytosolic side, which suggests a gating mechanism for the pore. Our results show that sampling methods and simulation times are sufficient to delineate even subtle effects of mutations on structure and function and to capture important long-timescale events, but also underline the importance of improving models further.

AB - We use an event study approach to examine the economic consequences of hospital admissions for adults in two datasets: survey data from the Health and Retirement Study, and hospitalization data linked to credit reports. For non-elderly adults with health insurance, hospital admissions increase out-of-pocket medical spending, unpaid medical bills and bankruptcy, and reduce earnings, income, access to credit and consumer borrowing. The earnings decline is substantial compared to the out-of-pocket spending increase, and is minimally insured prior to age-eligibility for Social Security Retirement Income. Relative to the insured non-elderly, the uninsured non-elderly experience much larger increases in unpaid medical bills and bankruptcy rates following a hospital admission. Hospital admissions trigger less than 5 percent of all bankruptcies.

AB - The de novo asymmetric total syntheses of daumone 1, daumone 3 along with 5 new analogs are described. The key steps of our approach are: the diastereoselective palladium catalyzed glycosylation reaction; the Noyori reduction of 2-acetylfuran and an ynone, which introduce the absolute stereochemistry of the sugar and aglycon portion of daumone; and an Achmatowicz rearrangement, an epoxidation and a ring opening installing the remaining asymmetry of daumone. The synthetic daumones 1 and 3 as well as related analogs were evaluated for dauer activity in C. elegans and for effects on hatching of the related nematode H. glycines. This data provides additional structure activity relationships (SAR) that further inform the study of nematode signaling. PMID- 29445248 TI - Friendship, curiosity and the city: Dementia friends and memory walks in Liverpool. AB - The city is not just a context for friendships or a problem to be solved through them; it can be a catalyst for these relationships, sparking and strengthening connections between individuals and groups. Shared experiences of and curiosity in cities - expressed through practices that include revisiting familiar places and exploring others for the first time - can draw people together in beneficial ways. These principles underpin a health and wellbeing agenda, pioneered in Liverpool, which encourages people to 'take notice' and 'connect' - two of five 'ways to wellbeing' promoted through the Liverpool Decade of Health and Wellbeing. This paper focusses upon one particular set of schemes and relationships which brings all this into focus: befriending schemes designed to support people with dementia, which engage with objects and places as catalysts for connection. These observations shed a broader light upon the meanings and uses of friendship, with particular reference to cities. PMID- 29445249 TI - Overexpression of GRK3, Promoting Tumor Proliferation, Is Predictive of Poor Prognosis in Colon Cancer. AB - Deregulation of G protein-coupled receptor kinase 3 (GRK3), which belongs to a subfamily of kinases called GRKs, acts as a promoter mechanism in some cancer types. Our study found that GRK3 was significantly overexpressed in 162 pairs of colon cancer tissues than in the matched noncancerous mucosa (P < 0.01). Based on immunohistochemistry staining of TMAs, GRK3 was dramatically stained positive in primary colon cancer (130/180, 72.22%), whereas it was detected minimally or negative in paired normal mucosa specimens (50/180, 27.78%). Overexpression of GRK3 was closely correlated with AJCC stage (P = 0.001), depth of tumor invasion (P < 0.001), lymph node involvement (P = 0.004), distant metastasis (P = 0.016), and histologic differentiation (P = 0.004). Overexpression of GRK3 is an independent prognostic indicator that correlates with poor survival in colon cancer patients. Consistent with this, downregulation of GRK3 exhibited decreased cell growth index, reduction in colony formation ability, elevated cell apoptosis rate, and impaired colon tumorigenicity in a xenograft model. Hence, a specific overexpression of GRK3 was observed in colon cancer, GRK3 potentially contributing to progression by mediating cancer cell proliferation and functions as a poor prognostic indicator in colon cancer and potentially represent a novel therapeutic target for the disease. PMID- 29445250 TI - Magneto-elastic coupling across the first-order transition in the distorted kagome lattice antiferromagnet Dy3Ru4Al12. AB - Structural changes through the first-order paramagnetic-antiferromagnetic phase transition of Dy3Ru4Al12 at 7 K have been studied by means of X-ray diffraction and thermal expansion measurements. The compound crystallizes in a hexagonal crystal structure of Gd3Ru4Al12 type (P63/mmc space group), and no structural phase transition has been found in the temperature interval between 2.5 and 300 K. Nevertheless, due to the spin-lattice coupling the crystal volume undergoes a small orthorhombic distortion of the order of 2*10-5 as the compound enters the antiferromagnetic state. We propose that the first-order phase transition is not driven by the structural changes but rather by the exchange interactions present in the system. PMID- 29445251 TI - [Sense of guilt in sexually abused children : Mediating role of avoidance coping on anxiety and self-esteem]. AB - Prior studies have suggested self-blame and sense of guilt as important elements associated with the effects of childhood sexual abuse on adult survivors (Canton Cortes, Canton, Justicia & Cortes, 2011). However, few studies have explored the potential impact of the sense of guilt on outcomes in child victims. This study examines the mediating role of avoidance coping on the relationship between sense of guilt and outcomes (anxiety and self-esteem) in sexually abused children. The sample consisted of 447 sexually abused children (319 girls and 128 boys) aged 6 to 12. Path analysis indicated that children with higher feelings of guilt about the abuse showed more anxiety and lower levels of self-esteem. Indirect effects also indicated that sense of guilt predicted avoidance coping, which in turn contributed to higher anxiety and lower self-esteem. This model, which fits the data well for both girls and boys, explains 24.4 % of the variance in anxiety and 11.2 % of the variance in self-esteem. Results suggest that sense of guilt is an important target for clinical intervention with sexually abused children. PMID- 29445252 TI - Implications of Measurement Assay Type in Design of HIV Experiments. AB - Time series measurements of circular viral episome (2-LTR) concentrations enable indirect quantification of persistent low-level Human Immunodeficiency Virus (HIV) replication in patients on Integrase-Inhibitor intensified Combined Antiretroviral Therapy (cART). In order to determine the magnitude of these low level infection events, blood has to be drawn from a patients at a frequency and volume that is strictly regulated by the Institutional Review Board (IRB). Once the blood is drawn, the 2-LTR concentration is determined by quantifying the amount of HIV DNA present in the sample via a PCR (Polymerase Chain Reaction) assay. Real time quantitative Polymerase Chain Reaction (qPCR) is a widely used method of performing PCR; however, a newer droplet digital Polymerase Chain Reaction (ddPCR) method has been shown to provide more accurate quantification of DNA. Using a validated model of HIV viral replication, this paper demonstrates the importance of considering DNA quantification assay type when optimizing experiment design conditions. Experiments are optimized using a Genetic Algorithm (GA) to locate a family of suboptimal sample schedules which yield the highest fitness. Fitness is defined as the expected information gained in the experiment, measured by the Kullback-Leibler Divergence (KLD) between the prior and posterior distributions of the model parameters. We compare the information content of the optimized schedules to uniform schedules as well as two clinical schedules implemented by researchers at UCSF and the University of Melbourne. This work shows that there is a significantly greater gain information in experiments using a ddPCR assay vs. a qPCR assay and that certain experiment design considerations should be taken when using either assay. PMID- 29445253 TI - Mitochondrial (Dys) Function in Inflammaging: Do MitomiRs Influence the Energetic, Oxidative, and Inflammatory Status of Senescent Cells? AB - A relevant feature of aging is chronic low-grade inflammation, termed inflammaging, a key process promoting the development of all major age-related diseases. Senescent cells can acquire the senescence-associated (SA) secretory phenotype (SASP), characterized by the secretion of proinflammatory factors fuelling inflammaging. Cellular senescence is also accompanied by a deep reshaping of microRNA expression and by the modulation of mitochondria activity, both master regulators of the SASP. Here, we synthesize novel findings regarding the role of mitochondria in the SASP and in the inflammaging process and propose a network linking nuclear-encoded SA-miRNAs to mitochondrial gene regulation and function in aging cells. In this conceptual structure, SA-miRNAs can translocate to mitochondria (SA-mitomiRs) and may affect the energetic, oxidative, and inflammatory status of senescent cells. We discuss the potential role of several of SA-mitomiRs (i.e., let-7b, miR-1, miR-130a-3p, miR-133a, miR-146a-5p, miR-181c 5p, and miR-378-5p), using miR-146a as a proof-of-principle model. Finally, we propose a comprehensive, metabolic, and epigenetic view of the senescence process, in order to amplify the range of possible approaches to target inflammaging, with the ultimate goal of decelerating the aging rate, postponing or blunting the development of age-related diseases. PMID- 29445254 TI - Cigarette Smoke Exposure Inhibits Bacterial Killing via TFEB-Mediated Autophagy Impairment and Resulting Phagocytosis Defect. AB - Introduction: Cigarette smoke (CS) exposure is the leading risk factor for COPD emphysema pathogenesis. A common characteristic of COPD is impaired phagocytosis that causes frequent exacerbations in patients leading to increased morbidity. However, the underlying mechanism is unclear. Hence, we investigated if CS exposure causes autophagy impairment as a mechanism for diminished bacterial clearance via phagocytosis by utilizing murine macrophages (RAW264.7 cells) and Pseudomonas aeruginosa (PA01-GFP) as an experimental model. Methods: Briefly, RAW cells were treated with cigarette smoke extract (CSE), chloroquine (autophagy inhibitor), TFEB-shRNA, CFTR(inh)-172, and/or fisetin prior to bacterial infection for functional analysis. Results: Bacterial clearance of PA01-GFP was significantly impaired while its survival was promoted by CSE (p < 0.01), autophagy inhibition (p < 0.05; p < 0.01), TFEB knockdown (p < 0.01; p < 0.001), and inhibition of CFTR function (p < 0.001; p < 0.01) in comparison to the control group(s) that was significantly recovered by autophagy-inducing antioxidant drug, fisetin, treatment (p < 0.05; p < 0.01; and p < 0.001). Moreover, investigations into other pharmacological properties of fisetin show that it has significant mucolytic and bactericidal activities (p < 0.01; p < 0.001), which warrants further investigation. Conclusions: Our data suggests that CS-mediated autophagy impairment as a critical mechanism involved in the resulting phagocytic defect, as well as the therapeutic potential of autophagy inducing drugs in restoring is CS-impaired phagocytosis. PMID- 29445255 TI - Cigarette Smoking and Adipose Tissue: The Emerging Role in Progression of Atherosclerosis. AB - Smoking is an established risk factor for atherosclerosis through several underlying pathways. Moreover, in the development of atherosclerotic plaque formation, obesity, defined as excess fat mass accumulation, also plays a vital role in dyslipidemia and insulin resistance. Substantial evidence shows that cigarette smoking induces multiple pathological effects in adipose tissue, such as differentiation of adipocytes, lipolysis, and secretion properties in adipose tissue. Therefore, there is an emerging speculation in which adipose tissue abnormality induced by smoking or nicotine is likely to accelerate the progression of atherosclerosis. Herein, this review aims to investigate the possible interplay between smoking and adipose tissue dysfunction in the development of atherosclerosis. PMID- 29445256 TI - Distinct Signature of Oxylipid Mediators of Inflammation during Infection and Asymptomatic Colonization by E. coli in the Urinary Bladder. AB - Urinary tract infection (UTI) is an extremely common infectious disease. Uropathogenic Escherichia coli (UPEC) is the predominant etiological agent of UTI. Asymptomatic bacteriuric E. coli (ABEC) strains successfully colonize the urinary tract resulting in asymptomatic bacteriuria (ABU) and do not induce symptoms associated with UTI. Oxylipids are key signaling molecules involved in inflammation. Based on the distinct clinical outcomes of E. coli colonization, we hypothesized that UPEC triggers the production of predominantly proinflammatory oxylipids and ABEC leads to production of primarily anti-inflammatory or proresolving oxylipids in the urinary tract. We performed quantitative detection of 39 oxylipid mediators with proinflammatory, anti-inflammatory, and proresolving properties, during UTI and ABU caused by genetically distinct E. coli strains in the murine urinary bladder. Our results reveal that infection with UPEC causes an increased accumulation of proinflammatory oxylipids as early as 6 h postinoculation, compared to controls. To the contrary, ABEC colonization leads to decreased accumulation of proinflammatory oxylipids at the early time point compared to UPEC infection but does not affect the level of proresolving oxylipids. This report represents the first comprehensive investigation on the oxylipidome during benign ABEC colonization observed in ABU and acute inflammation triggered by UPEC leading to UTI.

AB - A genuine microbiota resides in the lungs which emanates from the colonization by the oropharyngeal microbiota. Changes in the oropharyngeal microbiota might be the source of dysbiosis observed in the lower airways in patients suffering from asthma or cystic fibrosis (CF). To examine this hypothesis, we compared the throat microbiota from healthy children (n = 62) and that from children with asthma (n = 27) and CF (n = 57) aged 6 to 12 years using 16S rRNA amplicon sequencing. Our results show high levels of similarities between healthy controls and children with asthma and CF revealing the existence of a core microbiome represented by Prevotella, Streptococcus, Neisseria, Veillonella, and Haemophilus. However, in CF, the global diversity, the bacterial load, and abundances of 53 OTUs were significantly reduced, whereas abundances of 6 OTUs representing opportunistic pathogens such as Pseudomonas, Staphylococcus, and Streptococcus were increased compared to those in healthy controls controls and asthmatics. Our data reveal a core microbiome in the throat of healthy children that persists in asthma and CF indicating shared host regulation favoring growth of commensals. Furthermore, we provide evidence for dysbiosis with a decrease in diversity and biomass associated with the presence of known pathogens consistent with impaired host defense in children with CF. PMID- 29445260 TI - An approximation theorem and generic convergence for equilibrium problems. AB - In this paper, we prove an approximation theorem for equilibrium problems and provide theoretical support for many algorithms. Simon's bounded rationality is illustrated by an approximation theorem, that is, bounded rationality is approaching full rationality as its ultimate goal. Furthermore, by the methods of set-valued analysis, we obtain the generic uniqueness and generic convergence of the solutions of monotone equilibrium problems in the sense of Baire category. As applications, we investigate the optimization problem, variational inequality problem and saddle point problem as special cases. PMID- 29445259 TI - Significant Cytokine mRNA Expression Changes Immediately after Initiation of Cardiopulmonary Resuscitation. AB - Introduction: The purpose of this study was to evaluate immediate immunological changes following cardiopulmonary resuscitation (CPR). mRNA expression levels of selected immunomodulatory cytokines in out-of-hospital cardiac arrest (OHCA) survivors were detected and correlated to clinical parameter. Methods: OHCA survivors with sustained unconsciousness after return of spontaneous circulation (ROSC) were included. PAXgene whole blood samples were drawn immediately after initiation of CPR and subsequently after 6 h, 12 h, 24 h, 48 h, and 72 h. TNF alpha, IL-8, IL-10, and IL-1ra mRNA levels were quantified by RT-qPCR and compared to multiple organ failure, 30-day survival, and the induction of therapeutic hypothermia (TH). Results: 25 patients (63 +/- 15 years) were enrolled presenting a characteristic time-dependent cytokine profile in the early postresuscitation period. High initial TNF-alpha and IL-8 mRNA levels were followed by a significant decrease. IL-1ra mRNA levels significantly increased beginning after 6 h. Nonsurvivors showed significantly higher IL-8 mRNA levels immediately after CPR. TH induced significantly higher IL-1ra mRNA levels compared to normothermia. Conclusion: Significant mRNA cytokine expression changes are already detectable immediately after initiation of CPR. These expressional changes are significantly different depending on 30-day survival. TH seems to attenuate proinflammatory immune reaction by a significant increase of IL-1ra mRNA levels. This trial is registered with DRKS00012940. PMID- 29445261 TI - On asphericity of convex bodies in linear normed spaces. AB - In 1960, Dvoretzky proved that in any infinite dimensional Banach space X and for any [Formula: see text] there exists a subspace L of X of arbitrary large dimension epsilon-iometric to Euclidean space. A main tool in proving this deep result was some results concerning asphericity of convex bodies. In this work, we introduce a simple technique and rigorous formulas to facilitate calculating the asphericity for each set that has a nonempty boundary set with respect to the flat space generated by it. We also give a formula to determine the center and the radius of the smallest ball containing a nonempty nonsingleton set K in a linear normed space, and the center and the radius of the largest ball contained in it provided that K has a nonempty boundary set with respect to the flat space generated by it. As an application we give lower and upper estimations for the asphericity of infinite and finite cross products of these sets in certain spaces, respectively.

In this paper, we define degenerate Cauchy numbers of the third kind and give some identities for the degenerate Cauchy numbers of the third kind. In addition, we give some relations between four kinds of the degenerate Cauchy numbers, the Daehee numbers and the degenerate Bernoulli numbers. PMID- 29445263 TI - Noncompaction cardiomyopathy and heterotaxy syndrome. AB - Left ventricular noncompaction cardiomyopathy (LVNC) is characterized by compact and trabecular layers of the left ventricular myocardium. This cardiomyopathy may occur with congenital heart disease (CHD). Single cases document co-occurrence of LVNC and heterotaxy, but no data exist regarding the prevalence of this association. This study sought to determine whether a non-random association of LVNC and heterotaxy exists by evaluating the prevalence of LVNC in patients with heterotaxy. In a retrospective review of the Indiana Network for Patient Care, we identified 172 patients with heterotaxy (69 male, 103 female). Echocardiography and cardiac magnetic resonance imaging results were independently reviewed by two cardiologists to ensure reproducibility of LVNC. A total of 13/172 (7.5%) patients met imaging criteria for LVNC. The CHD identified in this subgroup included atrioventricular septal defects [11], dextrocardia [10], systemic and pulmonary venous return abnormalities [7], and transposition of the great arteries [5]. From this subgroup, 61% (n = 8) of the patients developed arrhythmias; and 61% (n = 8) required medical management for chronic heart failure. This study indicates that LVNC has increased prevalence among patients with heterotaxy when compared to the general population (0.014-1.3%) suggesting possible common genetic mechanisms. Interestingly, mice with a loss of function of Scrib or Vangl2 genes showed abnormal compaction of the ventricles, anomalies in cardiac looping, and septation defects in previous studies. Recognition of the association between LVNC and heterotaxy is important for various reasons. First, the increased risk of arrhythmias demonstrated in our population. Secondly, theoretical risk of thromboembolic events remains in any LVNC population. Finally, many patients with heterotaxy undergo cardiac surgery (corrective and palliative) and when this is associated with LVNC, patients should be presumed to incur a higher peri-operative morbidity based on previous studies. Further research will continue to determine long-term and to corroborate genetic pathways. PMID- 29445264 TI - Exercise program improved subjective dry eye symptoms for office workers. AB - Introduction: We investigated the benefits of a cognitive behavior therapy-based exercise program to reduce the dry eye symptoms of office workers. Materials and methods: We recruited 11 office workers with dry eye symptoms, aged 31-64 years, who voluntarily participated in group health guidance at a manufacturing company. Participants learned about the role of physical activity and exercise in enhancing wellness and performed an exercise program at home 3 days per week for 10 weeks. We estimated the indexes of body composition, dry eye symptoms, and psychological distress using the Dry Eye-Related Quality of Life Score and the World Health Organization's Subjective Well-Being Inventory questionnaires pre- and postintervention. Results: The 10-week exercise program and the questionnaires were completed by 48.1% (39 of 81) of the participants. Body composition did not change pre- and postintervention. However, the average of the Dry Eye-Related Quality of Life Score scores in participants with subjective dry eye significantly improved after the intervention. Moreover, the World Health Organization's Subjective Well-Being Inventory positive well-being score tended to increase after the intervention. Conclusion: In this study, we showed that a 10-week exercise program improved subjective dry eye symptoms of healthy office workers. Our study suggests that a cognitive behavior therapy-based exercise program can play an important role in the treatment of patients with dry eye disease. PMID- 29445266 TI - Are frail elderly patients treated in a CGA unit more satisfied with their hospital care than those treated in conventional acute medical care? AB - Objectives: Our aim was to study whether the acute care of frail elderly patients directly admitted to a comprehensive geriatric assessment (CGA) unit is superior to the care in a conventional acute medical care unit in terms of patient satisfaction. Design: TREEE (Is the TReatment of frail Elderly patients Effective in an Elderly care unit?) is a clinical, prospective, controlled, one-center intervention trial comparing acute treatment in CGA units and in conventional wards. Setting: This study was conducted in the NAL-Uddevalla county hospital in western Sweden. Participants: In this follow-up to the TREEE study, 229 frail patients, aged >=75 years, in need of acute in-hospital treatment, were eligible. Of these patients, 139 patients were included in the analysis, 72 allocated to the CGA unit group and 67 to the conventional care group. Mean age was 85 years and 65% were female. Intervention: Direct admittance to an acute elderly care unit with structured, systematic interdisciplinary CGA-based care, compared to conventional acute medical care via the emergency room. Measurements: The primary outcome was the satisfaction reported by the patients shortly after discharge from hospital. A four-item confidential questionnaire was used. Responses were given on a 4-graded scale. Results: The response rate was 61%. In unadjusted analyses, significantly more patients in the intervention group responded positively to the following three questions about the hospitalization: "Did you get the nursing from the ward staff that you needed?" (p=0.003), "Are you satisfied with the information you received on your diseases and medication?" (p=0.016), and "Are you satisfied with the planning before discharge from the hospital?" (p=0.032). After adjusted analyses by multiple regression, a significant difference in favor of the intervention remained for the first question (p=0.027). Conclusion: Acute care in a CGA unit with direct admission was associated with higher levels of patient satisfaction compared with conventional acute care via the emergency room. PMID- 29445265 TI - New frontiers in oncolytic viruses: optimizing and selecting for virus strains with improved efficacy. AB - Oncolytic viruses have demonstrated selective replication and killing of tumor cells. Different types of oncolytic viruses - adenoviruses, alphaviruses, herpes simplex viruses, Newcastle disease viruses, rhabdoviruses, Coxsackie viruses, and vaccinia viruses - have been applied as either naturally occurring or engineered vectors. Numerous studies in animal-tumor models have demonstrated substantial tumor regression and prolonged survival rates. Moreover, clinical trials have confirmed good safety profiles and therapeutic efficacy for oncolytic viruses. Most encouragingly, the first cancer gene-therapy drug - Gendicine, based on oncolytic adenovirus type 5 - was approved in China. Likewise, a second generation oncolytic herpes simplex virus-based drug for the treatment of melanoma has been registered in the US and Europe as talimogene laherparepvec. PMID- 29445267 TI - A patient and community-centered approach selecting endpoints for a randomized trial of a novel advance care planning tool. AB - Background: Despite a movement toward patient-centered outcomes, best practices on how to gather and refine patients' perspectives on research endpoints are limited. Advanced care planning (ACP) is inherently patient centered and would benefit from patient prioritization of endpoints for ACP-related tools and studies. Objective: This investigation sought to prioritize patient-centered endpoints for the content and evaluation of an ACP video being developed for patients undergoing major surgery. We also sought to highlight an approach using complementary engagement and research strategies to document priorities and preferences of patients and other stakeholders. Materials and methods: Endpoints identified from a previously published environmental scan were operationalized following rating by a caregiver co-investigator, refinement by a patient co investigator, review by a stakeholder committee, and validation by patients and family members. Finalized endpoints were taken to a state fair where members of the public who indicated that they or a loved one had undergone major surgery prioritized their most relevant endpoints and provided comments. Results: Of the initial 50 ACP endpoints identified from the review, 12 endpoints were selected for public prioritization. At the state fair, 359 individuals prioritized the endpoints, the highest ranking of which was having a meaningful conversation with a physician before surgery (57%). Conclusion: Using a novel combination of engagement and research techniques provided the opportunity to understand which endpoints were most important to patients and families and fostered framework development clarifying the differential contributions of engagement and research. Results from this study ultimately changed the content and evaluation of the ACP video. PMID- 29445268 TI - Genome-editing applications of CRISPR-Cas9 to promote in vitro studies of Alzheimer's disease. AB - Genetic variations play an important role in the clinical presentation and progression of Alzheimer's disease (AD), especially early-onset Alzheimer's disease. Hundreds of mutations have been reported with the majority resulting from alterations in beta-amyloid precursor protein (APP), presenilin 1 (PSEN1), or presenilin 2 (PSEN2) genes. The roles of these mutations in the pathogenesis of AD have been classically confirmed or refuted through functional studies, where the mutations are cloned, inserted into cell lines, and monitored for changes in various properties including cell survival, amyloid production, or Abeta42/40 ratio. However, these verification studies tend to be expensive, time consuming, and inconsistent. Recently, the clustered regularly interspaced short palindromic repeats-CRISPR-associated protein 9 (CRISPR-Cas9) system was developed, which improves sequence-specific gene editing in cell lines, organs, and animals. CRISPR-Cas9 is a promising tool for the generation of models of human genetic diseases and could facilitate the establishment of new animal AD models and the observation of dynamic bioprocesses in AD. Here, we recapitulated the history of CRISPR technology, recent progress, and, especially, its potential applications in AD-related genetic, animal modeling, and functional studies. PMID- 29445269 TI - An open-label, prospective interventional study of the tolerability and efficacy of 0.4 mg oral tamsulosin oral controlled absorption system in men with lower urinary tract symptoms associated with benign prostatic hyperplasia who are unsatisfied with treatment with 0.2 mg tamsulosin. AB - Purpose: The aim of this study was to investigate the efficacy and tolerability of switching from 0.2 mg tamsulosin to 0.4 mg tamsulosin oral controlled absorption system (OCAS) over a 12-week period in Taiwanese men with lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH). Patients and methods: Taiwanese male patients who were dissatisfied with treatment with 0.2 mg tamsulosin were enrolled in this clinical study and switched to 0.4 mg tamsulosin OCAS. Efficacy was assessed over a 12-week period by an International Prostate Symptom Score (IPSS) questionnaire and analysis of urinary flow by uroflowmetry. Results: A statistically significant improvement was observed in total IPSS scores from baseline (14.94+/-7.41, moderate) to 12 weeks (7.36+/-5.77, mild) in 81 patients who were switched from 0.2 to 0.4 mg tamsulosin OCAS (P<0.001). The IPSS subscores for storage, voiding, nocturia, and quality of life (QOL) were also significantly improved over the 12-week period. Uroflowmetry analysis demonstrated significantly increased maximum flow rate, average flow rate, and mean voided volume from baseline to the end of the 12-week period. The 0.4 mg tamsulosin OCAS dose was well tolerated, with only mild dizziness (five patients) and headache (two patients) as the most frequent adverse events. No clinically significant reduction was observed in blood pressure or vital signs. Conclusion: Treatment with 0.4 mg tamsulosin OCAS in Taiwanese men with LUTS associated with BPH who were dissatisfied with 0.2 mg tamsulosin significantly improved IPSS scores, urinary flow, and QOL and was well tolerated, suggesting that this should be the recommended dose offered to Taiwanese male patients. PMID- 29445270 TI - Alterations of the default mode network and cognitive impairments in patients with chronic obstructive pulmonary disease. AB - Background and objectives: Cognitive impairment is a common extrapulmonary comorbidity in COPD patients. The default mode network (DMN) plays a critical role in maintaining the normal activities of humans, and its function can be evaluated by resting state functional magnetic resonance imaging. The aim of this study was to investigate the correlations between cognition and function changes of the DMN in COPD patients. Methods: One hundred and thirteen eligible participants including 30 control subjects and 83 COPD patients matched for demographic characteristics were recruited. All participants performed cognitive function tests and underwent resting state functional magnetic resonance imaging. Results: The total cognitive function scores of COPD patients were significantly different from those of control subjects (P<0.05) and worsened with the degree of airflow obstruction. The activated brain regions in the DMN of COPD patients were less than those of normal controls. Six activated brain regions in the DMN were found to develop significantly different functional connectivity (FC) values among the subjects. Meanwhile, the FC values of the left posterior cingulate cortex and left hippocampus correlated well with cognitive functions and pulmonary function. Conclusion: COPD patients have cognitive impairments that correlate well with disease severity. FC changes in activated brain regions in the DMN may predict cognitive impairment, and the left posterior cingulate cortex and left hippocampus may be important brain regions related to cognitive impairment in COPD patients. PMID- 29445271 TI - Immune cell response to strenuous resistive breathing: comparison with whole body exercise and the effects of antioxidants. AB - Background/hypothesis: Whole body exercise (WBE) changes lymphocyte subset percentages in peripheral blood. Resistive breathing, a hallmark of diseases of airway obstruction, is a form of exercise for the inspiratory muscles. Strenuous muscle contractions induce oxidative stress that may mediate immune alterations following exercise. We hypothesized that inspiratory resistive breathing (IRB) alters peripheral blood lymphocyte subsets and that oxidative stress mediates lymphocyte subpopulation alterations following both WBE and IRB. Patients and methods: Six healthy nonathletes performed two WBE and two IRB sessions for 45 minutes at 70% of VO2 maximum and 70% of maximum inspiratory pressure (Pimax), respectively, before and after the administration of antioxidants (vitamins E, A, and C for 75 days, allopurinol for 30 days, and N-acetylcysteine for 3 days). Blood was drawn at baseline, at the end of each session, and 2 hours into recovery. Lymphocyte subsets were determined by flow cytometry. Results: Before antioxidant supplementation at both WBE end and IRB end, the natural killer cell percentage increased, the T helper cell (CD3+ CD4+) percentage was reduced, and the CD4/CD8 ratio was depressed, a response which was abolished by antioxidants only after IRB. Furthermore, at IRB end, antioxidants promoted CD8+ CD38+ and blunted cytotoxic T-cell percentage increase. CD8+ CD45RA+ cell percentage changes were blunted after antioxidant supplementation in both WBE and IRB. Conclusion: We conclude that IRB produces (as WBE) changes in peripheral blood lymphocyte subsets and that oxidative stress is a major stimulus predominantly for IRB-induced lymphocyte subset alterations. PMID- 29445272 TI - CT densitometry in emphysema: a systematic review of its clinical utility. AB - Background: The aim of the study was to assess the relationship between computed tomography (CT) densitometry and routine clinical markers in patients with chronic obstructive pulmonary disease (COPD) and alpha-1 anti-trypsin deficiency (AATD). Methods: Multiple databases were searched using a combination of pertinent terms and those articles relating quantitatively measured CT densitometry to clinical outcomes. Studies that used visual scoring only were excluded, as were those measured in expiration only. A thorough review of abstracts and full manuscripts was conducted by 2 reviewers; data extraction and assessment of bias was conducted by 1 reviewer and the 4 reviewers independently assessed for quality. Pooled correlation coefficients were calculated, and heterogeneity was explored. Results: A total of 112 studies were identified, 82 being suitable for meta-analysis. The most commonly used density threshold was 950 HU, and a significant association between CT density and all included clinical parameters was demonstrated. There was marked heterogeneity between studies secondary to large variety of disease severity within commonly included cohorts and differences in CT acquisition parameters. Conclusion: CT density shows a good relationship to clinically relevant parameters; however, study heterogeneity and lack of longitudinal data mean that it is difficult to compare studies or derive a minimal clinically important difference. We recommend that international consensus is reached to standardize CT conduct and analysis in future COPD and AATD studies. PMID- 29445273 TI - New bacterial growth in bronchial secretions after bronchoscopic valve implantation. AB - Background: Bronchoscopic valve implantation is an established treatment in selected patients with severe lung emphysema. There is evidence in literature of increased bacterial colonization of various implants. So far, it is unclear if an increased bacterial colonization can also be observed after endoscopic valve therapy. Methods: Retrospective analysis of patients with examination of the bronchial secretions for presence or change of bacterial growth before and after valve implantation. Results: Overall, 144 patients who underwent bronchoscopic follow-up after valve implantation were included in this analysis. Prior to valve placement, only 7 out of 144 consecutive emphysema patients (5%) presented with evidence of bacterial colonization, whereas 137 patients (95%) showed no bacterial growth prior to valve placement. One hundred seven out of the 137 patients (78%) showed new bacterial growth after valve implantation. Almost 38% of the patients who presented with a new bacterial growth had evidence of Viridans streptococci, Rothia mucilaginousa and Neisseria species simultaneously, as bacterial colonization. Pathogenic bacterial growth was recorded for Staphylococcus aureus (18%), Pseudomonas aeruginosa (13%) and Stenotrophomonas maltophilia (9%) microorganisms. There was also a significant bacterial growth by Moraxella catarrhalis (26%) and anaerobic bacteria (23%), especially in patients with complete atelectasis after successful endoscopic lung volume reduction. For all of the 7 patients, the presented initial bacterial colonization showed a change in the flora after bronchoscopy valve implantation. Conclusion: In this study we observed an increased bacterial colonization in the long term after valve implantation. This finding needs further evaluation regarding its possible clinical relevance but should be taken into consideration in the follow-up of these patients. PMID- 29445274 TI - Endoplasmic reticulum chaperone GRP78 mediates cigarette smoke-induced necroptosis and injury in bronchial epithelium. AB - Introduction: Bronchial epithelial cell death and airway inflammation induced by cigarette smoke (CS) have been involved in the pathogenesis of COPD. GRP78, belonging to heat shock protein 70 family, has been implicated in cell death and inflammation, while little is known about its roles in COPD. Here, we demonstrate that GRP78 regulates CS-induced necroptosis and injury in bronchial epithelial cells. Materials and methods: GRP78 and necroptosis markers were examined in human bronchial epithelial (HBE) cell line, primary mouse tracheal epithelial cells, and mouse lungs. siRNA targeting GRP78 gene and necroptosis inhibitor were used. Expression of inflammatory cytokines, mucin MUC5AC, and related signaling pathways were detected. Results: Exposure to CS significantly increased the expression of GRP78 and necroptosis markers in HBE cell line, primary mouse tracheal epithelial cells, and mouse lungs. Inhibition of GRP78 significantly suppressed CS extract (CSE)-induced necroptosis. Furthermore, GRP78-necroptosis cooperatively regulated CSE-induced inflammatory cytokines such as interleukin 6 (IL6), IL8, and mucin MUC5AC in HBE cells, likely through the activation of nuclear factor (NF-kappaB) and activator protein 1 (AP-1) pathways, respectively. Conclusion: Taken together, our results demonstrate that GRP78 promotes CSE induced inflammatory response and mucus hyperproduction in airway epithelial cells, likely through upregulation of necroptosis and subsequent activation of NF kappaB and AP-1 pathways. Thus, inhibition of GRP78 and/or inhibition of necroptosis could be the effective therapeutic approaches for the treatment of COPD. PMID- 29445275 TI - Burden of COPD in Nepal. AB - Background: COPD is a globally significant public health problem and is the second leading cause of mortality. This study presents the health burden of COPD in Nepal using the Global Burden of Disease (GBD) study 2016 dataset. Methods: This study used the data from the GBD repository presenting morbidity and mortality attributed to COPD, by sex and age. In GBD 2016, due to a lack of the primary source of data in Nepal, estimations on morbidity and mortality of COPD were based on its predictive covariates. Years of life lost (YLLs) were calculated based on the cause of death estimations, applying GBD's Cause of Death Ensemble modeling. Likewise, years lived with disability (YLDs) were calculated by multiplying the prevalence of each sequela by the disability weight. Disability-adjusted life years (DALYs) were derived as the sum of YLLs and YLDs. Results: Between 1990 and 2016, the estimated age-standardized mortality rate due to COPD was decreasing for both genders, but the decline was much higher among males. Unlike the high rate of incidence among males, the age-standardized DALYs were found to be high among females (2,274.9 [95% UI: 1,702.0-2,881.5] per 100,000). YLLs contributed around 80% of DALYs due to COPD in 2016. Age standardized YLLs rate was higher among females, with a value of 1,860 (95% uncertainty interval (UI): 1,282.8-2,472.8) vs 1,547.6 (95% UI: 992.1-2,018.5) among the males per 100,000 population. Conclusion: The prevalence and incidence of COPD remained almost stationary over the years, but still very high. Though the incidence and prevalence of disease were high among males, the death rate and DALYs were more significant among females throughout the years. If the current situation prevails, the burden of COPD will continue to increase in the country. Hence, comprehensive social, environmental, and behavioral approaches to curtail the risk factors along with early identification, treatment, and management of COPD is of utmost importance. PMID- 29445278 TI - Increased viability of fibroblasts when pretreated with ceria nanoparticles during serum deprivation. AB - Conditions of cellular stress are often the cause of cell death or dysfunction. Sustained cell stress can lead to several health complications, such as extensive inflammatory responses, tumor growth, and necrosis. To prevent disease and protect human tissue during these conditions and to avoid medication side effects, nanomaterials with unique characteristics have been applied to biological systems. This paper introduces the pretreatment in human dermal fibroblasts with cerium oxide nanoparticles during nutritional stress. For this purpose, human dermal fibroblast cells received cell culture media with concentrations of 250 ug/mL and 500 ug/mL of nano-cerium oxide before being exposed to 24, 48, and 72 hours of serum starvation. Contrast images demonstrated higher cell confluence and cell integrity in cells pretreated with ceria nanoparticles compared to untreated cells. It was confirmed by MTS assay after 72 hours of serum starvation that higher cell viability was achieved with ceria nanoparticles. The results demonstrate the potential of cerium oxide nanoparticles as protective agents during cellular starvation. PMID- 29445276 TI - Redox-responsive F127-folate/F127-disulfide bond-d-alpha-tocopheryl polyethylene glycol 1000 succinate/P123 mixed micelles loaded with paclitaxel for the reversal of multidrug resistance in tumors. AB - Introduction: The development of nanodrug carriers utilizing tumor microenvironment has become a hotspot in reversing multidrug resistance (MDR). Materials and methods: This study synthesized a redox-sensitive copolymer, Pluronic F127-disulfide bond-d-alpha-tocopheryl polyethylene glycol 1000 succinate (FSST), through the connection of the reduction-sensitive disulfide bond between F127 and d-alpha-tocopheryl polyethylene glycol 1000 succinate. This polymer could induce the elevation of reactive oxygen species (ROS) levels, ultimately resulting in cytotoxicity. Moreover, the redox-responsive mixed micelles, F127-folate (FA)/FSST/P123 (FFSSTP), based on FSST, Pluronic F127-FA, and Pluronic P123, were prepared to load paclitaxel (PTX). Results: The in vitro release study demonstrated that FFSSTP/PTX accelerated the PTX release through the breakage of disulfide bond in reductive environment. In cellular experiment, FFSSTP/PTX induced significant apoptosis in PTX-resistant MCF-7/PTX cells through inhibiting adenosine triphosphate (ATP)-binding cassette proteins from pumping out PTX by interfering with the mitochondrial function and ATP synthesis. Furthermore, FFSSTP/PTX induced apoptosis through elevating the intracellular levels of ROS. Conclusion: FFSSTP could become a potential carrier for the treatment of MDR tumors. PMID- 29445277 TI - Effects of silica-gentamicin nanohybrids on osteogenic differentiation of human osteoblast-like SaOS-2 cells. AB - Introduction: In recent years, there has been an increasing interest in silica (SiO2) nanoparticles (NPs) as drug delivery systems. This interest is mainly attributed to the ease of their surface functionalization for drug loading. In orthopedic applications, gentamicin-loaded SiO2 NPs (nanohybrids) are frequently utilized for their prolonged antibacterial effects. Therefore, the possible adverse effects of SiO2-gentamicin nanohybrids on osteogenesis of bone-related cells should be thoroughly investigated to ensure safe applications. Materials and methods: The effects of SiO2-gentamicin nanohybrids on the cell viability and osteogenic differentiation of human osteoblast-like SaOS-2 cells were investigated, together with native SiO2 NPs and free gentamicin. Results: The results of Cell Count Kit-8 (CCK-8) assay show that both SiO2-gentamicin nanohybrids and native SiO2 NPs reduce cell viability of SaOS-2 cells in a dose dependent manner. Regarding osteogenesis, SiO2-gentamicin nanohybrids and native SiO2 NPs at the concentration range of 31.25-125 MUg/mL do not influence the osteogenic differentiation capacity of SaOS-2 cells. At a high concentration (250 MUg/mL), both materials induce a lower expression of alkaline phosphatase (ALP) but an enhanced mineralization. Free gentamicin at concentrations of 6.26 and 9.65 MUg/mL does not significantly influence the cell viability and osteogenic differentiation capacity of SaOS-2 cells. Conclusions: The results of this study suggest that both SiO2-gentamicin nanohybrids and SiO2 NPs show cytotoxic effects to SaOS-2 cells. Further investigation on the effects of SiO2-gentamicin nanohybrids on the behaviors of stem cells or other regular osteoblasts should be conducted to make a full evaluation of the safety of SiO2-gentamicin nanohybrids in orthopedic applications. PMID- 29445279 TI - EGFR-targeted photodynamic therapy by curcumin-encapsulated chitosan/TPP nanoparticles. AB - Background: Photodynamic therapy (PDT) is an effective therapy for cancers and is a minimally invasive therapy with low dark toxicity and limited side effects. PDT employs the combination of photosensitizers with a specific light source to produce reactive oxygen species (ROS) to damage tumor cells. Methods: We fabricated nanoparticles encapsulating curcumin through crosslinking chitosan and tripolyphosphate (TPP). Additionally, the chitosan was conjugated to epidermal growth factor in order to target the epidermal growth factor receptor (EGFR), overexpressed on cancer cells. To investigate PDT using fabricated nanoparticles, we measured cell viabilities and ROS production in relation to EGFR overexpressing gastric cancer cells and non-cancer gastric cells. Results: The targeting nanoparticles displayed a superior PDT effect in the cancer cell, with a resultant approximately fourfold decrease in the IC50. The PDT mechanism of curcumin-encapsulated nanoparticles is further identified as the generation of 1O2, the major pathway in PDT. Conclusion: These curcumin-encapsulated chitosan/TPP nanoparticles are a promising targeted-PDT against EGFR overexpressing cancers. PMID- 29445280 TI - The differences between patients with panic disorder and healthy controls in psychophysiological stress profile. AB - Background: Alarming somatic symptoms, in particular, cardiovascular symptoms, are the characteristic feature of panic attacks. Increased cardiac mortality and morbidity have been found in these patients. Power spectral analysis of electrocardiogram R-R intervals is known to be a particularly successful tool in the detection of autonomic instabilities in various clinical disorders. Our study aimed to compare patients with panic disorder and healthy controls in heart rate variation (HRV) parameters (very-low-frequency [VLF], low-frequency [LF], and high-frequency [HF] band components of R-R interval) in baseline and during the response to the mental task. Subjects and methods: We assessed psychophysiological variables in 33 patients with panic disorder (10 men, 23 women; mean age 35.9+/-10.7 years) and 33 age- and gender-matched healthy controls (10 men, 23 women; mean age 35.8+/-12.1 years). Patients were treatment naive. Heart rate, blood pressure, muscle tension, and HRV in basal conditions and after the psychological task were assessed. Power spectrum was computed for VLF (0.003-0.04 Hz), LF (0.04-0.15 Hz), and HF (0.15-0.40 Hz) bands using fast Fourier transformation. Results: In the baseline period, the VLF band was significantly lower in panic disorder group compared to controls (p<0.005). In the period of mental task, the LF/HF ratio was significantly higher in panic disorder patients compared to controls (p<0.05). No significant differences were found in the remaining parameters. There was a significant difference in DeltaHF and DeltaLF/HF ratio between patients and controls, with Delta increasing in patients and decreasing in controls. Conclusion: These findings revealed that patients suffering from panic disorder were characterized by relative sympathetic dominance (reactivity) in response to mental stress compared with healthy controls. PMID- 29445281 TI - Suicidal drug overdose following stroke in elderly patients: a retrospective population-based cohort study. AB - Purpose: The purpose of this study was to investigate the incidence and risk of suicidal drug overdose (SDO) after stroke in older patients. Methods: We enrolled patients aged 60-99 years who were diagnosed with new-onset stroke between 2002 and 2013 and age-, sex-, and index-year-matched controls who did not have stroke. Patients with a history of SDO before enrollment were excluded. Both groups were observed until December 31, 2013. The primary end point was the occurrence of newly diagnosed SDO. The cumulative incidence rates of the study and control groups were estimated using the Kaplan-Meier method. Furthermore, we used the Cox proportional hazards model to identify risk factors for SDO. Results: We selected 22,770 individuals. Among them, 11,385 were older patients (aged 60-99 years) who had newly diagnosed stroke and 11,385 were controls. Of the 22,770 individuals, 275 (1.21%) had SDO during a mean follow-up period of 5.33+/-3.30 years, comprising 191 (1.68%) from the stroke group and 84 (0.74%) from the control group. Older patients with stroke had a significantly higher risk of SDO than the controls (adjusted hazard ratio: 2.288, 95% confidence interval [CI]: 1.746 2.999, p<0.001). Moreover, in older patients with stroke, the risk significantly increased with the number of stroke events. Patients with depressive disorder or coronary disease had an increased risk of SDO. Additionally, benzodiazepines and anticoagulants were the two most commonly prescribed medications for SDO. Conclusion: Clinicians should be aware of the risk of SDO and risk factors in older patients with stroke. Psychological assessment and medication monitoring should be incorporated into current clinical diagnoses in neurology and treatments following stroke. PMID- 29445282 TI - Orexin/hypocretin levels in the cerebrospinal fluid and characteristics of patients with myotonic dystrophy type 1 with excessive daytime sleepiness. AB - Purpose: Myotonic dystrophy type 1 (DM1) is often characterized by excessive daytime sleepiness (EDS) and sleep-onset rapid eye movement periods caused by muscleblind-like protein 2. The EDS tends to persist even after treatment of sleep apnea. We measured the cerebrospinal fluid (CSF) orexin levels in DM1 patients with EDS and compared the clinical characteristics with narcolepsy type 1 and idiopathic hypersomnia (IHS) patients. Patients and methods: We measured the CSF orexin levels in 17 DM1 patients with EDS and evaluated subjective sleepiness using the Epworth Sleepiness Scale (ESS), objective sleepiness using mean sleep latency (MSL), and sleep apnea using apnea-hypopnea index (AHI). We compared the ESS scores and MSL between decreased (<=200 pg/mL) and normal (>200 pg/mL) CSF orexin group in DM1 patients. Furthermore, we compared the CSF orexin levels, ESS scores, MSL, and AHI among patients with DM1, narcolepsy type 1 (n=46), and IHS (n=30). Results: Seven DM1 patients showed decreased CSF orexin levels. There were significant differences in the ESS scores and MSL between decreased and normal CSF orexin groups in DM1 patients. The ESS scores showed no significant difference among patients with DM1, narcolepsy type 1, and IHS. The MSL in DM1 and IHS patients were significantly higher than narcolepsy type 1 patients (p=0.01, p<0.001). The AHI in DM1 patients was significantly higher than narcolepsy type 1 patients (p=0.042) and was insignificantly different from IHS patients. The CSF orexin levels in DM1 patients were significantly lower than IHS patients and higher than narcolepsy type 1 patients (p<0.001, p<0.001). Conclusion: The CSF orexin levels of DM1 patients moderately decreased compared to those of IHS patients as the control group. However, the EDS of DM1 patients may not be explained by only orexin deficiency. PMID- 29445283 TI - Application value of selected serum indicators in the differential diagnosis of geriatric depression and transient depressive state. AB - Background: Transient depressive state (TDS) is a transient, negative emotional state caused by certain events or situations. Because of the similarity in depressive symptoms between depression and TDS that arise within 2 weeks of their onset, it is difficult to distinguish TDS from depression. The aims of the present study were to investigate the application value of selected serum indicators in the differential diagnosis of geriatric depression and TDS in the early stage and to provide evidence for treatment. Patients and methods: In this study, a total of 274 elderly patients were divided into the depression group (n=144) and the TDS group (n=130). All participants' serum samples were collected, and 9 selected serum indicators were analyzed. Afterward, 90 patients with depression and 90 patients with TDS were used to build the diagnostic model. A binary logistic regression analysis was used to establish regression models, and the area under the receiver operating characteristic (ROC) curve was drawn. Finally, another 54 patients with depression and 40 patients with TDS were used to validate our model. Results: For the 9 screening serum indicators, the 3 serum indicators selected to build the regression model were BDNF (P=0.001), IL-1beta (P<0.001), and cortisol (P<0.001). The regression equation was Y = 1/[1 + e-( 16.258 - 0.018 (BDNF) + 0.256 (IL-1beta) + 0.093 (Cortisol))], and the ROC curve of combined detection was 0.926. The diagnostic rate of the logistic model was 89.36%. Conclusion: The logistic regression model and ROC curves based on serum levels of BDNF, IL-1beta, and cortisol could distinguish depression from TDS in early stage, which could provide assistance to the differential diagnosis of geriatric depression and TDS. PMID- 29445284 TI - Efficacy, acceptability, and safety of adjunctive aripiprazole in treatment resistant depression: a meta-analysis of randomized controlled trials. AB - Background: Treatment-resistant depression (TRD) is common and potentially life threatening in adults, and the benefits and risks of adjunctive aripiprazole in these patients remain controversial. Therefore, we conducted a meta-analysis of randomized controlled trials (RCTs) to assess the efficacy, acceptability, safety, and quality of life of adjunctive aripiprazole in patients with TRD. Methods: RCTs published in PubMed, Web of Science, and Embase were systematically reviewed to evaluate the efficacy and safety profiles of TRD patients who were treated with adjunctive aripiprazole. The main outcome measures included response rate, remission rate, changes from baseline in Montgomery-Asberg Depression Rating Scale (MADRS), Clinical Global Impression-severity (CGI-S), Clinical Global Impression-improvement (CGI-I), 17-Item Hamilton Rating Scale for Depression (HAM-D17), Sheehan Disability scale (SDS), and Inventory of Depressive Symptomatology Self-Report Scale (IDS-SR), discontinuation due to adverse events, and adverse events. Risk ratio (RR) or weight mean difference with 95% confidence intervals (CIs) were pooled using a fixed-effects or random-effects model according to the heterogeneity among studies. Results: A total of 8 RCTs involving 2,260 patients were included in this meta-analysis. Adjunctive aripiprazole was associated with a significantly higher remission rate (RR =1.64, 95% CI: 1.42 to 1.89; P<0.001) and response rate (RR =1.45, 95% CI: 1.13 to 1.87; P=0.004) than other treatments. Moreover, adjunctive aripiprazole had greater changes in MADRS score, CGI-S score, CGI-I score, HAM-D17 score, SDS score, and IDS-SR score. There were more patients treated with adjunctive aripiprazole who discontinued their treatments due to adverse events. The incidence of adverse events was significantly higher in the adjunctive aripiprazole group than in other treatment groups. Conclusion: The adjunctive aripiprazole showed benefits in improving the response rate, remission rate, and the quality of life in patients with TRD. However, clinicians should interpret these findings with caution due to the evidence of potential treatment-related side effects. PMID- 29445285 TI - The effect of exercise on cancer-related fatigue in cancer survivors: a systematic review and meta-analysis. AB - Objective: The objective of the study was to conduct systematic review and meta analysis to establish the effect of exercise interventions on cancer-related fatigue (CRF) in cancer survivors, compared to non-exercise intervention controls. Methods: Trials published between January 1st 2000 and August 17th 2016 were included through PubMed database search and search of references. Eligible trials compared the effect of an exercise intervention on CRF compared to non exercise intervention controls, with CRF as primary outcome and measured by validated self-report questionnaire, in cancer survivors not receiving palliative care. We evaluated risk of bias of individual trials following Cochrane Quality criteria. We performed a random-effects meta-analysis in the low risk of bias trials with intervention type, exercise intensity, adherence, and cancer type as moderators, and also performed meta-regression analyses and a sensitivity analysis including the high risk of bias trials. Results: Out of 274 trials, 11 met the inclusion criteria, of which six had low risk of bias. Exercise improved CRF with large effect size (Cohen's d 0.605, 95% CI 0.235-0.975) with no significant difference between types of cancer. Aerobic exercise (Delta=1.009, CI 0.222-1.797) showed a significantly greater effect than a combination of aerobic and resistance exercises (Delta=0.341, CI 0.129-0.552). Moderator and meta regression analyses showed high adherence yielding best improvements. Conclusion: Exercise has a large effect on CRF in cancer survivors. Aerobic interventions with high adherence have the best result. PMID- 29445286 TI - Glia maturation factor-beta: a potential therapeutic target in neurodegeneration and neuroinflammation. AB - Glia maturation factor-beta (GMFB) is considered to be a growth and differentiation factor for both glia and neurons. GMFB has been found to be upregulated in several neuroinflammation and neurodegeneration conditions. It may function by mediating apoptosis and by modulating the expression of superoxide dismutase, granulocyte-macrophage colony-stimulating factor, and neurotrophin. In this review, we mainly discussed the role of GMFB in several neuroinflammatory and neurodegenerative diseases. On review of the literature, we propose that GMFB may be a promising therapeutic target for neuroinflammatory and neurodegenerative diseases. PMID- 29445287 TI - Patient knowledge on stroke risk factors, symptoms and treatment options. AB - Background: Public campaigns focus primarily on stroke symptom and risk factor knowledge, but patients who correctly recognize stroke symptoms do not necessarily know the reason for urgent hospitalization. The aim of this study was to explore knowledge on stroke risk factors, symptoms and treatment options among acute stroke and transient ischemic attack patients. Methods: This prospective study included patients admitted to the stroke unit at the Department of Neurology, Akershus University Hospital, Norway. Patients with previous cerebrovascular disease, patients receiving thrombolytic treatment and patients who were not able to answer the questions in the questionnaire were excluded. Patients were asked two closed-ended questions: "Do you believe that stroke is a serious disorder?" and "Do you believe that time is of importance for stroke treatment?". In addition, patients were asked three open-ended questions where they were asked to list as many stroke risk factors, stroke symptoms and stroke treatment options as they could. Results: A total of 173 patients were included, of whom 158 (91.3%) confirmed that they regarded stroke as a serious disorder and 148 patients (85.5%) considered time being of importance. In all, 102 patients (59.0%) could not name any treatment option. Forty-one patients (23.7%) named one or more adequate treatment options, and they were younger (p<0.001) and had higher educational level (p<0.001), but had a nonsignificant shorter prehospital delay time (p=0.292). Conclusion: The level of stroke treatment knowledge in stroke patients seems to be poor. Public campaigns should probably also focus on information on treatment options, which may contribute to reduce prehospital delay and onset-to-treatment-time. PMID- 29445288 TI - Prognostic significance of epidermal growth factor receptor expression in glioma patients. AB - Purpose: There is a great controversy regarding the prognostic significance of epidermal growth factor receptor (EGFR) in glioma patients. The current meta analysis was conducted to evaluate the effect of abnormal EGFR expression on overall survival in glioma patients. Materials and methods: A comprehensive literature search of PubMed, EMBASE, Google Scholar, Web of Science, and Cochrane Library was conducted. The combined hazard ratio (HR) and its 95% confidence intervals (CIs) were used to evaluate the association between EGFR expression and survival in glioma. Results: A total of 476 articles were screened, and 17 articles containing 1,458 patients were selected. The quality assessment of the included studies was performed by the Newcastle-Ottawa Scale. Overexpression of EGFR was found to be an indicator of poor prognosis in overall survival in glioma patients (HR =1.72, 95% CI 1.32-2.25, P=0.000, random effect) and glioblastoma multiforme patients (HR =1.57, 95% CI 1.15-2.14, P=0.004, random effect). Subgroup analysis was conducted to explore the source of high heterogeneity. Conclusion: This meta-analysis indicated that high expression of EGFR may serve as a biomarker for poor prognosis in glioma patients. PMID- 29445289 TI - Expression of Nemo-like kinase in cervical squamous cell carcinoma: a clinicopathological study. AB - Objective: Nemo-like kinase (NLK) has been reported to play different roles in tumors. However, the role of NLK in cervical squamous cell carcinoma (CSCC) remains unknown. In this study, we explored the clinical significance including survival of NLK protein expression in CSCCs. Patients and methods: Immunohistochemical method was performed using tissues from 130 patients with CSCC. The associations between NLK expression and the clinicopathological factors and prognosis of CSCCs were evaluated. Statistical analyses were performed using the chi-square test, the multivariate Cox proportional hazard model, and the Kaplan-Meier method. Results: Immunohistochemical staining analysis showed that NLK was localized predominately in the nucleus of the tumor cells, and increased NLK expression was detected in 71 (54.6%) of 130 patients. NLK overexpression significantly correlated with higher histological grade (P=0.001), vascular/lymphatic invasion (P=0.010), lymph node metastasis (P=0.012), and recurrence (P=0.022). Patients with elevated NLK expression had poorer overall survival (OS) and disease-free survival (DFS) (P=0.006 and P=0.004, respectively) compared with patients with decreased NLK expression. Multivariate Cox analysis demonstrated that NLK overexpression was an independent factor for OS and DFS (P=0.034 and P=0.025, respectively). Conclusion: NLK may be a valuable biomarker for predicting the prognosis of CSCC patients and may serve as a potential target for cancer therapy. PMID- 29445290 TI - Molecular features of giant-cell carcinoma of the lung: a case report and literature review. AB - Giant-cell carcinoma of the lung (GCCL) is a rare histological form of poorly differentiated non-small-cell lung cancer, which is classified as a subtype of pulmonary sarcomatoid carcinomas. In this case report, we describe the case of a 50-year-old Chinese male who presented with a pulmonary nodule in the right upper lobe of his lung. After thoracoscopic lobectomy, a histopathologic diagnosis of GCCL was made. He did well postoperatively, showing no local recurrence or distal disease in a 7-year follow-up period. Furthermore, for this case, we also analyzed 295 tumor-related driver genes with high-throughput sequencing technology. We found that treatment using MEK inhibitor, CDK 4/6 inhibitor, and TP53 inhibitor may provide a new therapeutic direction for GCCL. Therefore, complete tumor excision is the best choice of treatment strategy at the early stage of GCCL and gene target therapy may be a new therapeutic option for this disease. PMID- 29445291 TI - Raptor mediates the antiproliferation of cardamonin by mTORC1 inhibition in SKOV3 cells. AB - Purpose: Cardamonin inhibits the proliferation of SKOV3 cells by suppressing the mammalian target of rapamycin complex 1 (mTORC1). However, the mechanism of cardamonin on mTORC1 inhibition has not been well demonstrated. The regulatory associated protein of TOR (Raptor) is an essential component of mTORC1. Here, we investigated the role of Raptor in the mTORC1 inhibition effect of cardamonin in SKOV3 cells. Methods: The expression of Raptor was knockdown by small interfering RNA (siRNA). The expressions of specific binding proteins of mTORC1 were analyzed by Western blotting, and the cell proliferation was detected by methyl thiazolyl tetrazolium (MTT) assay. Results: Rapamycin, AZD8055, and cardamonin inhibited the activity of mammalian target of rapamycin (mTOR). Different from rapamycin and AZD8055, cardamonin suppressed the phosphorylation and protein expression of Raptor. Transfected with Raptor siRNA, the mTOR activation and proliferation of SKOV3 cells were decreased, and these effects were strengthened by cardamonin in Raptor siRNA SKOV3 cells. Cardamonin interfered with the lysosomal colocalization of mTOR with lysosomal associated membrane protein 2 (LAMP2), which was also hindered by Raptor siRNA. Furthermore, cardamonin strengthened the inhibitory effect on the lysosomal localization of mTOR in Raptor siRNA cells. Conclusion: Our results suggested that Raptor mainly mediated the inhibition of cardamonin on mTORC1 in SKOV3 cells. PMID- 29445293 TI - Clinical utility of ustekinumab in Crohn's disease. AB - The introduction of anti-tumor necrosis factor (TNF) therapy marked an important milestone in the management of moderate-to-severe Crohn's disease (CD). However, there remains a pressing demand for alternative therapeutic options for patients with primary nonresponse, secondary loss of response, or intolerable side effects to conventional treatment and TNF antagonists. Ustekinumab (UST) is a fully human IgG1kappa monoclonal antibody that inhibits the p40 subunit shared by the proinflammatory cytokines, the interleukin (IL)-12 and -23. This blockade leads to dampening of the inflammatory cascade and differentiation of inflammatory T cells. The clinical development program for UST in CD includes dose finding Phase II (Crohn's Evaluation of Response to Ustekinumab Anti-Interleukin-12/23 for Induction [CERTIFI]) and the pivotal Phase III (UNITI) trials that demonstrated both the clinical efficacy and safety in anti-TNF-naive and anti-TNF-exposed patients. Real-world evidence has further defined the role of UST in CD management. In this review, we discuss the mechanism of action of UST, describe the results of the randomized controlled trials with this agent, and review the real-world efficacy and safety data from observational cohorts. Finally, we identify areas of future research in the IL-12/23 inflammatory pathway and discuss the positioning of this novel therapeutic option in CD treatment algorithms. PMID- 29445292 TI - Late-onset asthma: current perspectives. AB - Because the pathophysiology of asthma has diverse characteristics, to manage the disease effectively, it is important for clinicians to distinguish among the clinical phenotypes. Among them, adult-onset asthma, that is, late-onset asthma (LOA), is increasing because of the aging of the population. The phenotype of LOA is largely divided into two types according to the presence or absence of eosinophilic inflammation, T-helper (Th)2- and non-Th2-associated LOA. Especially in Th2 LOA related to rhinosinusitis, as pulmonary function at onset is poor and asthma exacerbations occur frequently, it is important to detect this phenotype in the early phase by using a biomarker of Th2-type inflammation such as fractional exhaled nitric oxide (FENO). As non-Th2-LOA is often resistant to corticosteroids, this phenotype often requires another treatment strategy such as macrolide, diet, or smoking cessation. We often struggle with the management of LOA patients due to a lack of evidence; therefore, the elucidation of the mechanism of LOA contributes to increased efficiency of diagnosis and treatment of LOA. Age-related immune system and structural changes are thought to be associated with the pathophysiology of LOA. In the former case, changes in inflammatory cell function such as variations in the innate immune response and acquisition of autoimmunity or upregulation of oxidative stress are thought to be involved in the mechanism. Meanwhile, the latter can also become triggers or exacerbating factors of LOA via enhancement of airway hyperresponsiveness, decline in lung function, increased air trapping, and reduction in chest wall compliance. Therefore, appropriate individualized management in LOA may be possible through precisely assessing the pathophysiology based on age-related functional changes, including the immune and structural system. PMID- 29445294 TI - Anxiety and depression in general practice outpatients: the long-term change process. AB - Background and objectives: Patients who come for a consultation at a general practice clinic as outpatients often suffer from background anxiety and depression. The psychological state of such patients can alleviate naturally; however, there are cases when these symptoms persist. This study investigated the realities and factors behind anxiety/depression becoming prolonged. Methods: Participants were 678 adult patients, who came to Department of General Medicine at Chiba University Hospital within a 1-year period starting from April 2012 and who completed the Hospital Anxiety and Depression Scale (HADS) during their initial consultation. Participants whose Anxiety or Depression scores in the HADS, or both, were 8 points or higher were defined as being within the anxiety/depression group, with all other participants making up the control group. A telephone interview was also conducted with participants. Furthermore, age, sex, the period from the onset of symptoms to the initial consultation at our department, the period from the initial department consultation to the telephone survey, and the existence of mental illness at the final department diagnosis were investigated. Results: A total of 121 patients (17.8% response rate) agreed to the phone survey. The HADS score during the phone survey showed that the anxiety/depression group had a significantly higher score than the control group. The HADS scores obtained between the initial consultation and telephone survey showed a positive correlation. Logistic regression analysis extracted "age" and the "continuation of the symptoms during the initial consultation" as factors that prolonged anxiety/depression. Conclusion: Anxiety and depression in general practice outpatients have the possibility of becoming prolonged for an extended period of time. Being aged 65 years or over and showing a continuation of symptoms past the initial consultation are the strongest factors associated with these prolonged conditions. When patients with anxiety and depression exhibit these risk factors, they should be further evaluated for treatment. PMID- 29445295 TI - The effect of exercise frequency on neuropathic pain and pain-related cellular reactions in the spinal cord and midbrain in a rat sciatic nerve injury model. AB - Background: Exercise regimens are established methods that can relieve neuropathic pain. However, the relationship between frequency and intensity of exercise and multiple cellular responses of exercise-induced alleviation of neuropathic pain is still unclear. We examined the influence of exercise frequency on neuropathic pain and the intracellular responses in a sciatic nerve chronic constriction injury (CCI) model. Materials and methods: Rats were assigned to four groups as follows: CCI and high-frequency exercise (HFE group), CCI and low-frequency exercise (LFE group), CCI and no exercise (No-Ex group), and naive animals (control group). Rats ran on a treadmill, at a speed of 20 m/min, for 30 min, for 5 (HFE) or 3 (LFE) days a week, for a total of 5 weeks. The 50% withdrawal threshold was evaluated for mechanical sensitivity. The activation of glial cells (microglia and astrocytes), expression of brain-derived neurotrophic factor (BDNF) and MU-opioid receptor in the spinal dorsal horn and endogenous opioid in the midbrain were examined using immunohistochemistry. Opioid receptor antagonists (naloxone) were administered using intraperitoneal injection. Results: The development of neuropathic pain was related to the activation of glial cells, increased BDNF expression, and downregulation of the MU-opioid receptor in the ipsilateral spinal dorsal horn. In the No-Ex group, neuropathic pain showed the highest level of mechanical hypersensitivity at 2 weeks, which improved slightly until 5 weeks after CCI. In both exercise groups, the alleviation of neuropathic pain was accelerated through the regulation of glial activation, BDNF expression, and the endogenous opioid system. The expression of BDNF and endogenous opioid in relation to exercise-induced alleviation of neuropathic pain differed in the HFE and LFE groups. The effects of exercise-induced alleviation of mechanical hypersensitivity were reversed by the administration of naloxone. Conclusion: The LFE and HFE program reduced neuropathic pain. Our findings indicated that aerobic exercise-induced alleviated neuropathic pain through the regulation of glial cell activation, expression of BDNF in the ipsilateral spinal dorsal horn, and the endogenous opioid system. PMID- 29445296 TI - The ultrasound-guided retrolaminar block: volume-dependent injectate distribution. AB - Purpose: The ultrasound-guided retrolaminar block is one of the newer and simpler alternatives to the traditional, often technically challenging, paravertebral (PV) block. Its feasibility, safety, and efficacy have already been clinically demonstrated in patients with multiple rib fractures using higher volumes of local anesthetic, when compared with the traditional approach. The primary aim of this observational anatomical study was to assess the spread of local anesthetic from the retrolaminar injection point to the PV space and its volume dependence. Second, we assessed the incidence of epidural and contralateral PV spread in the both groups. Methods: Ten fresh porcine cadavers were randomized into 2 groups (n=5 each) to receive ultrasound-guided retrolaminar injections at Th4-Th5 level with either 10 mL (low-volume group) or 30 mL (high-volume group) of 2% lidocaine and methylene blue mixture. After the procedure, the cadavers were dissected and frozen. Cross-section cuts (~1 cm thick) were performed to evaluate the injectate spread. Results: In the high-volume group, injectate spread from the retrolaminar to the PV space was observed in all specimens (5 out of 5; 100%), while in the low-volume group, no apparent spread to the PV space was found (0 out of 5; 0%). No epidural or contralateral PV spread was observed in any of the specimens. Conclusion: Following ultrasound-guided retrolaminar injections in fresh porcine cadavers, injectate spread from the retrolaminar tissue plane to the PV space is strongly volume dependent, suggesting that, clinically, high local anesthetic volumes maybe critical for achieving regional anesthesia and analgesia consistent with traditional PV blockade. PMID- 29445298 TI - Presence of pain on three or more days of the week is associated with worse patient reported outcomes in adults with sickle cell disease. AB - While acute episodic pain is the hallmark of sickle cell disease (SCD), transition to chronic pain is a major cause of morbidity and impaired quality of life. One of the core diagnostic criteria used by Analgesic, Anesthetic, and Addiction Clinical Trial Translations Innovations Opportunities and Networks American Pain Society Pain Taxonomy (AAPT) to define chronic SCD pain is the presence of pain on a "majority of days" in the past 6 months in one or more locations. The frequency characteristic of "majority of days" is adapted from the criteria of 15 days or more per month, used to define chronic migraine, but there are inadequate data to support this cutoff in SCD. Using an existing dataset of adults with SCD who completed patient-reported outcomes of pain interference, physical functioning, anxiety, depression, and fatigue using the National Institutes of Health (NIH) patient-reported outcomes measures information system (PROMIS) short-form instruments, we examined the association of the presence of pain on 3 or more days per week with patient-reported outcomes of functioning. In unadjusted analyses, presence of pain on 3 or more days a week was associated with higher median PROMIS scores of pain interference, anxiety, and depression. Median PROMIS scores of fatigue and physical function were worse in women compared with men in unadjusted analyses. We did not find any difference in median PROMIS pain scores between adults aged <=35 years compared with those aged >=35 years. In linear regression models, after adjustment for age and sex, the presence of pain on 3 or more days a week was found to be associated with worse pain interference and anxiety. These data support the clinical relevance of the frequency characteristic of pain on a "majority of days" in the definition of chronic SCD pain, and provide the rationale for prospective studies to validate the clinical definition of chronic pain in SCD. PMID- 29445297 TI - Managing severe pain and abuse potential: the potential impact of a new abuse deterrent formulation oxycodone/naltrexone extended-release product. AB - Proper management of severe pain represents one of the most challenging clinical dilemmas. Two equally important goals must be attained: the humanitarian/medical goal to relieve suffering and the societal/legal goal to not contribute to the drug abuse problem. This is an age-old problem, and the prevailing emphasis placed on one or the other goal has resulted in pendulum swings that have resulted in either undertreatment of pain or the current epidemic of misuse and abuse. In an effort to provide efficacious strong pain relievers (opioids) that are more difficult to abuse by the most dangerous routes of administration, pharmaceutical companies are developing products in which the opioid is manufactured in a formulation that is designed to be tamper resistant. Such a product is known as an abuse-deterrent formulation (ADF). ADF opioid products are designed to deter or resist abuse by making it difficult to tamper with the product and extracting the opioid for inhalation or injection. To date, less than a dozen opioid formulations have been approved by the US Food and Drug Administration to carry specific ADF labeling, but this number will likely increase in the coming years. Most of these products are extended-release formulations. PMID- 29445299 TI - Choosing wisely after publication of level I evidence in breast cancer radiotherapy. AB - Background: Recent trials in early-stage breast cancer support hypofractionated whole-breast radiotherapy (WBRT) as part of breast-conserving therapy (BCT). Evidence also suggests that radiotherapy (RT) omission may be reasonable for some patients over 70 years. Among radiation-delivery techniques, intensity-modulated RT (IMRT) is more expensive than 3-dimensional conformal RT (3DCRT). Based on this evidence, in 2013, the American Society for Radiation Oncology (ASTRO) recommended hypofractionated schedules for women aged >=50 years with early-stage breast cancer and avoiding routine use of IMRT for WBRT. To assess response to level I evidence and adherence to ASTRO recommendations, we evaluated the pattern of RT use for early-stage breast cancer at our National Comprehensive Cancer Network institution from 2006 to 2008 and 2011 to 2013 and compared the results with national trends. Methods: Data from a prospective database were extracted to include patients treated with BCT, aged >=50 years, with histologic findings of invasive ductal carcinoma, stage T1-T2N0M0, estrogen receptor-positive, and HER2 normal. We retrospectively reviewed the medical records and estimated costs based on 2016 Hospital Outpatient Prospective Payment System (technical fees) and Medicare Physician Fee Schedule (professional fees). Results: Among 55 cases from 2006 to 2008, treatment regimens were 11% hypofractionated, 69% traditional schedule, and 20% RT omission (29% of patients were aged >70 years). Among 83 cases from 2011 to 2013, treatment regimens were 54% hypofractionated, 19% traditional schedule, and 27% RT omission (48% of patients were aged >70 years). 3DCRT was used for all WBRT treatments. Direct medical cost estimates were as follows: 15 fractions 3DCRT, $7,197.87; 15 fractions IMRT, $11,232.33; 25 fractions 3DCRT, $9,731.39; and 25 fractions IMRT, $16,877.45. Conclusion: Despite apparent resistance to shorter radiation schedules in the United States, we demonstrate that rapid practice change in response to level I evidence is feasible. Wider adoption of evidence-based guidelines in early-stage breast cancer may substantially lower health care costs and improve convenience for patients without sacrificing oncologic outcomes. PMID- 29445301 TI - Comparative effectiveness of early-line nab-paclitaxel vs. paclitaxel in patients with metastatic breast cancer: a US community-based real-world analysis. AB - Background: Real-world analyses of treatments for patients with metastatic breast cancer are limited. We evaluated the comparative effectiveness of nab-paclitaxel vs. paclitaxel in patients with metastatic breast cancer using data from an electronic medical record database from community practices across the USA. Methods: We performed a retrospective cohort study using fully de-identified data from an independent US electronic medical record platform of patients with metastatic breast cancer initiating single-agent nab-paclitaxel or paclitaxel as a first- or second-line treatment from December 1, 2010 to October 6, 2014. The clinical efficacy objectives were time to treatment discontinuation (TTD) and time to next treatment (TTNT). Subgroup analyses were performed in patients with 2 types of metastatic breast cancer as follows: 1) hormone receptor-positive and human epidermal growth factor receptor 2 negative, and 2) triple-negative disease. Results: This analysis included 925 patients. Patients receiving nab paclitaxel vs. paclitaxel had significantly longer TTD (median 4.2 vs. 2.8 months, P<0.0001) and TTNT (median 6.0 vs. 4.2 months, P<0.0001); similar outcomes were observed for patients with hormone receptor-positive/human epidermal growth factor receptor 2 negative disease. Compared with paclitaxel, nab-paclitaxel was associated with significantly longer TTD in patients with triple-negative disease. nab-Paclitaxel was associated with significantly less all-grade neuropathy, anemia, pain, and diarrhea than paclitaxel. Antiemetic and antihistamine use were significantly less frequent with nab-paclitaxel vs. paclitaxel, whereas use of granulocyte colony-stimulating factor, hydrating agents, and bone-directed therapy to decrease skeletal-related events were more frequent. Conclusion: nab-Paclitaxel demonstrated improved clinical effectiveness compared with paclitaxel when examining TTD and TTNT in patients with metastatic breast cancer in a real-world setting. PMID- 29445300 TI - Gastric cancer: epidemiology, prevention, classification, and treatment. AB - Gastric cancer is the second most common cause of cancer-related deaths in the world, the epidemiology of which has changed within last decades. A trend of steady decline in gastric cancer incidence rates is the effect of the increased standards of hygiene, conscious nutrition, and Helicobacter pylori eradication, which together constitute primary prevention. Avoidance of gastric cancer remains a priority. However, patients with higher risk should be screened for early detection and chemoprevention. Surgical resection enhanced by standardized lymphadenectomy remains the gold standard in gastric cancer therapy. This review briefly summarizes the most important aspects of gastric cancers, which include epidemiology, risk factors, classification, diagnosis, prevention, and treatment. The paper is mostly addressed to physicians who are interested in updating the state of art concerning gastric carcinoma from easily accessible and credible source. PMID- 29445302 TI - Anastomotic reinforcement with omentoplasty reduces anastomotic leakage for minimally invasive esophagectomy with cervical anastomosis. AB - Purpose: Anastomotic leakage is the most feared postoperative complication after esophagectomy. Omentoplasty, wrapping the omentum around the alimentary tract anastomosis, is thought to decrease the anastomotic leakage rate. The purpose of this clinical study is to investigate the use of omentoplasty to reinforce cervical esophagogastrostomy after minimally invasive esophagectomy (MIE). Patients and methods: In this retrospective study, the data of 160 consecutive patients who underwent cervical esophagogastrostomy after MIE between September 2012 and May 2015 were analyzed, 87 who underwent omentoplasty (group A) and 73 who did not undergo omentoplasty (group B). The primary outcome was the incidence of anastomotic leakage and anastomotic strictures after the operation. Secondary outcomes were other complications and mortality rate. Univariate and multivariate analysis of variables associated with an increased risk for anastomotic leak was performed. Results: The median age was 61 years (range, 37-82 years). The anastomotic leakage rates were 4.6% (4/87) in group A and 15.1% (11/73) in group B (P = 0.023). There was no statistical significance in anastomotic stricture rates between group A (6.9%) and group B (9.6%; P = 0.535). No difference was noted in other complications between the groups. There was a trend toward lower leak-associated mortality rates for group A (0%) compared with that for group B (4.1%). Conclusion: Cervical esophagogastrostomy with omentoplasty is more effective than esophagogastrostomy without omentoplasty for the prevention of anastomotic leakage in MIE with cervical anastomosis. Omentoplasty could be used as an adjunct technique to reduce the incidence of anastomotic leakage in cervical esophagogastrostomy following MIE. PMID- 29445303 TI - Uncemented three-dimensional-printed prosthetic replacement for giant cell tumor of distal radius: a new design of prosthesis and surgical techniques. AB - Introduction: Currently, it is challenging to treat giant cell tumor (GCT) of distal radius. For Campanacci grade III or recurrent GCTs, en bloc resection has been accepted as a better treatment option. Although numerous methods are available for reconstruction, all of them have some limitations in joint function and complications. In this study, our aims were to treat the GCT of distal radius with uncemented three-dimensional (3D)-printed prosthesis and to present and evaluate the surgical techniques and short-term outcomes. Methods: Between September 2015 and March 2017, 11 patients with distal radius GCTs were treated with personalized uncemented 3D-printed prosthesis. The preoperative/postoperative pain, range of motion, and grip strengths of all patients were evaluated. Oncological results, complications, and degenerative changes in the wrist joint were evaluated. Functional outcomes were assessed according to the disabilities of the arm, shoulder, and hand (DASH) questionnaire and Mayo wrist scoring systems. Results: The average follow-up was 14.45 months (range, 8-18 months). There was a significant decrease in the mean postoperative visual analog scale score (2.33) compared with the preoperative score (5.22; p<0.001). The mean DASH score and Mayo wrist score of the wrist joint function were 18.7 and 72, respectively. There was no local recurrence or lung metastasis. No complication associated with prosthesis was observed, including aseptic loosening, subluxation, and breakage. Joint space narrowing, or disuse osteoporosis, was also not found in all cases. Conclusion: En bloc resection and reconstruction with a personalized uncemented 3D-printed prosthesis can be alternative options to treat Campanacci grade III or recurrent GCTs of distal radius and can result in short-term oncologic salvage, good postoperative function, and low complication rate. However, a long-term follow-up is required to determine the outcome. PMID- 29445304 TI - Prevalence of medication errors in primary health care at Bahrain Defence Force Hospital - prescription-based study. AB - Background: One of the important activities that physicians - particularly general practitioners - perform is prescribing. It occurs in most health care facilities and especially in primary health care (PHC) settings. Objectives: This study aims to determine what types of prescribing errors are made in PHC at Bahrain Defence Force (BDF) Hospital, and how common they are. Methods: This was a retrospective study of data from PHC at BDF Hospital. The data consisted of 379 prescriptions randomly selected from the pharmacy between March and May 2013, and errors in the prescriptions were classified into five types: major omission, minor omission, commission, integration, and skill-related errors. Results: Of the total prescriptions, 54.4% (N=206) were given to male patients and 45.6% (N=173) to female patients; 24.8% were given to patients under the age of 10 years. On average, there were 2.6 drugs per prescription. In the prescriptions, 8.7% of drugs were prescribed by their generic names, and 28% (N=106) of prescriptions included an antibiotic. Out of the 379 prescriptions, 228 had an error, and 44.3% (N=439) of the 992 prescribed drugs contained errors. The proportions of errors were as follows: 9.9% (N=38) were minor omission errors; 73.6% (N=323) were major omission errors; 9.3% (N=41) were commission errors; and 17.1% (N=75) were skill-related errors. Conclusion: This study provides awareness of the presence of prescription errors and frequency of the different types of errors that exist in this hospital. Understanding the different types of errors could help future studies explore the causes of specific errors and develop interventions to reduce them. Further research should be conducted to understand the causes of these errors and demonstrate whether the introduction of electronic prescriptions has an effect on patient outcomes. PMID- 29445305 TI - Implantation of intracorneal ring segments in pediatric patients: long-term follow-up. AB - Purpose: To analyze the long-term outcomes of intracorneal ring segments (ICRS) implantation for keratoconus management in pediatric patients. Methods: Retrospective case series review of the long-term (>5 years) outcomes of Intacs(r) ICRS implantation for keratoconus in pediatric patients (age <18 years old at the time of surgery) between January 2008 and December 2011 at Ophthalmology Department of Hospital de Santo Antonio. Demographic data, follow up time, preoperative and postoperative uncorrected visual acuity (UCVA) and best corrected visual acuity (BCVA) in decimal scale, and corneal topography were evaluated. Statistical analysis was done using SPSS for windows (version 24). Significance was set at p<0.0125. Results: Fourteen eyes of 14 patients, with a mean age of 15.36 years (range 10-18 years), were included in this study. All patients had been diagnosed with keratoconus with reported progression in the 6 months prior to surgery. Follow-up time was 6.36+/-0.97 years. UCVA and BCVA improved after ICRS implantation (p<0.0125). Keratometry (K) minimum (Kmin) and K maximum (Kmax) decreased after surgery (p<0.0125). During follow-up, UCVA, BCVA, Kmin, and Kmax values ranged, showing a tendency to worsen at the end of follow up. However, statistically significant differences were not observed. Conclusion: ICRS implantation showed good visual and topographic results in pediatric patients. Long-term follow-up suggests that, despite ICRS implantation, there is still progression of keratoconus. To the best of our knowledge, there are no reports regarding the long-term efficacy of ICRS implantation in pediatric patients. PMID- 29445306 TI - Repository corticotropin injection in patients with rheumatoid arthritis resistant to biologic therapies. AB - Introduction: Although synthetic and biologic disease-modifying antirheumatic drugs are available, many patients with rheumatoid arthritis have a difficult-to control disease and need other treatment options. Repository corticotropin injection (RCI) may alleviate symptoms and exacerbations in patients with refractory disease. Methods: Nine patients with refractory rheumatoid arthritis were included in this study. Patients were maintained on their baseline therapies with a minimum of 7.5 mg prednisone daily. RCI was given daily at 40 U for 7 days. Patients who had an adequate disease response were given 40 U twice weekly through Week 12. For patients who had inadequate disease response, the dose was increased to 80 U daily for 7 days, followed by 80 U twice weekly through Week 12. Results: The primary endpoint was >1.2 point reduction in the Disease Activity Score 28 using C-reactive protein (DAS28-CRP) at Week 12. Secondary endpoints were improvements in Health Assessment Questionnaire-Disease Index and Functional Assessment of Chronic Illness Therapy scores. Six of the nine patients met the primary endpoint. The average change in DAS28-CRP from baseline to Week 12 was numerically greater with 40 U than with 80 U RCI. Functional Assessment of Chronic Illness Therapy and Health Assessment Questionnaire-Disease Index improved as early as Week 1, and the improvements remained throughout treatment. Conclusion: There was no association between cortisol levels and low-dose RCI response. No serious adverse events occurred. RCI produced a clinically meaningful reduction in markers of disease activity, improved health-related quality of life, and a favorable safety profile. The response rate to RCI was substantial and shows promise in this difficult-to-treat population. PMID- 29445308 TI - CPR in medical TV shows: non-health care student perspective. AB - Introduction: There are over a dozen medical shows airing on television, many of which are during prime time. Researchers have recently become more interested in the role of these shows, and the awareness on cardiopulmonary resuscitation. Several cases have been reported where a lay person resuscitated a family member using medical TV shows as a reference. The purpose of this study is to examine and evaluate college students' perception on cardiopulmonary resuscitation and when to shock using an automated external defibrillator based on their experience of watching medical TV shows. Methods: A total of 170 students (nonmedical major) were surveyed in four different colleges in the United States. The survey consisted of questions that reflect their perception and knowledge acquired from watching medical TV shows. A stepwise regression was used to determine the significant predictors of "How often do you watch medical drama TV shows" in addition to chi-square analysis for nominal variables. Results: Regression model showed significant effect that TV shows did change students' perception positively (p<0.001), and they would select shock on asystole as the frequency of watching increases (p=0.023). Conclusion: The findings of this study show that high percentage of nonmedical college students are influenced significantly by medical shows. One particular influence is the false belief about when a shock using the automated external defibrillator (AED) is appropriate as it is portrayed falsely in most medical shows. This finding raises a concern about how these shows portray basic life support, especially when not following American Heart Association (AHA) guidelines. We recommend the medical advisors in these shows to use AHA guidelines and AHA to expand its expenditures to include medical shows to educate the public on the appropriate action to rescue an out-of hospital cardiac arrest patient. PMID- 29445309 TI - The role of pairing an anesthesiology rotation with the general surgery clerkship: positive impact on surgical and perioperative education. AB - Background: The use of an anesthesiology rotation in the realm of surgical education is not very well studied. Several studies show the importance of an anesthesiology rotation in the grand scheme of undergraduate medical education. However, its importance in perioperative medicine and surgical education is not very well understood. This study attempts to look at this relationship and determine whether or not a temporal relationship between this anesthesiology rotation and a surgical rotation is important. Methods: I used an online survey tool to survey medical students who took the anesthesiology rotation (required rotation) in 2014 and 2015 (when rotation was coupled to surgical rotation) and compared those data to the data of students who took the rotation in 2016 (when the rotation was not coupled to surgery). I asked several questions looking at the importance of the anesthesiology rotation to surgical education and to perioperative medicine. Results: Having a required anesthesiology rotation appears to add value to the general surgery rotation in undergraduate medical education. Furthermore, when this rotation is paired with the general surgery rotation, it appears that the students learn more about perioperative medicine than when the rotation is paired with other "advanced" rotation. Conclusion: The pairing of anesthesiology with a general surgery rotation does indeed improve the perioperative medicine education and knowledge of students. Students appreciate having a week of anesthesiology with the surgical rotation, and they note that it adds value to the general surgery rotation. PMID- 29445310 TI - Training in emerging advances in chronic hepatitis C infection in Pakistan: the Teach - Pak project. AB - Purpose: Viral hepatitis B and C represent the primary health challenge confronting Asia and Pakistan. With direct-acting antiviral therapy for hepatitis C, patients will be treated by general physicians (GPs) and will need training through continuing medical education (CME). Blended learning is a combination of didactic teaching with online, self-paced learning, and it has not been evaluated as a CME tool for general physicians. We aimed to compare the change in physician's knowledge about chronic viral hepatitis following a blended learning educational program. Methods: Participants enrolled in a 6 week blended learning program comprising three modules, each of 2 weeks duration. These were: 1) epidemiology and prevention of viral hepatitis; 2) diagnosis and assessment of hepatitis; and 3) treatment of hepatitis. Activities were primarily web based with some face-to-face interactive sessions. All study material was available on the Teach - Pak website. Discussions, questions, and comments were encouraged. An overall pre-and postintervention knowledge assessment was performed, in addition to individual module assessments. Results: A total of 48 participants completed the program; 39 passed (81.25%). The participants were from diverse backgrounds with variable previous training. The pass rate rose from 16.1% at the start of the program to 81.2% at the conclusion. The mean pretest score was 26.0 (standard deviation =4.36), while the mean posttest score was 34.6 (standard deviation =5.15), showing an increase in the mean score of 8.56 points. Eighty four percent had completed at least one credit hour for CME as compared to those who did not pass the posttest (44.4% p-value =0.02). No significant differences in results of posttest were observed in the categories of participant's age, years since graduation, or years of experience. The participants were satisfied with the blended learning mode of teaching. Conclusion: Blended learning is an efficient way to impart hepatitis CME to a diverse group of postgraduate physicians. PMID- 29445307 TI - Sleep problems during the menopausal transition: prevalence, impact, and management challenges. AB - A substantial number of women experience sleep difficulties in the approach to menopause and beyond, with 26% experiencing severe symptoms that impact daytime functioning, qualifying them for a diagnosis of insomnia. Here, we review both self-report and polysomnographic evidence for sleep difficulties in the context of the menopausal transition, considering severity of sleep complaints and links between hot flashes (HFs) and depression with poor sleep. Longitudinal population based studies show that sleep difficulties are uniquely linked with menopausal stage and changes in follicle-stimulating hormone and estradiol, over and above the effects of age. A major contributor to sleep complaints in the context of the menopausal transition is HFs, and many, although not all, HFs are linked with polysomnographic-defined awakenings, with HF-associated wake time contributing significantly to overall wakefulness after sleep onset. Some sleep complaints may be comorbid with depressive disorders or attributed to sleep-related breathing or movement disorders, which increase in prevalence especially after menopause, and for some women, menopause, age, and environmental/behavioral factors may interact to disrupt sleep. Considering the unique and multifactorial basis for sleep difficulties in women transitioning menopause, we describe clinical assessment approaches and management options, including combination treatments, ranging from cognitive behavioral therapy for insomnia to hormonal and nonhormonal pharmacological options. Emerging studies suggest that the impact of severe insomnia symptoms could extend beyond immediate health care usage and quality of life issues to long-term mental and physical health, if left untreated in midlife women. Appropriate treatment, therefore, has immediate benefit as well as advantages for maintaining optimal health in the postmenopausal years. PMID- 29445311 TI - Fetal growth restriction in rural Bangladesh: a prospective study. AB - Background: Fetal growth restriction (FGR) and low birth weight(LBW) are serious public health problems. In developing countries, the incidence of low birth weight is predominantly the result of FGR, and both low birth weight and FGR are associated with neonatal death and later growth and development. Fetal growth charts are important for assessing the size of the fetus during pregnancy. The aims of this study were to describe the fetal growth pattern of a population in rural Bangladesh where maternal undernutrition is prevalent and to compare the timing of FGR in that population with WHO and INTERGROWTH- 21st international reference values. Methods: From November 2001 to October 2003, pregnant women were recruited in Matlab, a sub district of Bangladesh, and underwent three follow-up ultrasound examinations during pregnancy for measurement of the parameters of the fetal head, abdomen, and femur. The data were fitted to a linear-cubic model, and the derived values were compared with international reference values. Results: A total of 2678 singleton pregnancies were included in the analyses. The mean (SD) maternal age was 25.9 (5.8) years (range, 14-47 years). The mean (SD) early pregnancy BMI was 20.1 (2.6) kg/m2, and 27.6% of the women were underweight (BMI < 18.5 kg/m2). The growth of the biparietal diameter and abdominal circumference was significantly smaller throughout the pregnancy than the reference values (P <= 0.05). Moreover, a larger deviation in the growth of Bangladeshi fetuses was observed after 28 weeks of gestation when compared with the WHO and INTERGROWTH-21st reference fetal growth charts (P <= 0.05). After 28 weeks of gestation, the average Bangladesh estimated fetal weight gain per week of gestational age was significantly lower than the WHO estimated fetal weight by as much as 67.4 g (P <= 0.001). Conclusions: The present population based study showed that fetuses were smaller in the third trimester when compared with the reference charts. Growth faltering started in the second trimester for all the biometric parameters for the head, abdomen, and femur. This finding provides more challenges concerning nutritional interventions. PMID- 29445312 TI - Treatment of Recurrent or Metastatic Uterine Adenosarcoma. AB - Purpose: This study retrospectively evaluated overall survival (OS) by treatment of recurrent or metastatic uterine adenosarcoma including surgery, radiation, chemotherapy, and hormonal therapy and evaluated OS and progression-free survival (PFS) after 1st line systemic chemotherapy. Methods: 78 patients with recurrent or metastatic adenosarcoma comprised the study population. The Kaplan-Meier method was used to estimate OS and PFS. The log-rank test was performed to test the difference in survival between groups. Results: Median OS from diagnosis of recurrent or metastatic disease was 1.8 yrs. OS was influenced by pathology on recurrence, p=0.035. Median OS differed by surgery for 1st recurrence 26.3 months versus 15.1 months. OS was not influenced by chemotherapy, p=0.58, palliative radiation, p=0.58, or hormonal therapy, p=0.15. The response rate (CR + PR) per RECIST 1.1 for chemotherapy was 31.2% for doxorubicin-based regimens and 14.3% for gemcitabine/docetaxel. OS since 1st line chemotherapy was not significantly different among chemotherapy regimens. However, the median PFS was superior for doxorubicin/ifosfamide (15.4 months) compared to gemcitabine/docetaxel (5.0 months), platinum-based regimens (5.7 mo), or other doxorubicin-based regimens (6.5 months). Conclusion: These results suggest that surgery is an important treatment modality for recurrent or metastatic uterine adenosarcoma, and the most effective chemotherapeutics are doxorubicin/ifosfamide and gemcitabine/docetaxel. PMID- 29445313 TI - Little composite dark matter. AB - We examine the dark matter phenomenology of a composite electroweak singlet state. This singlet belongs to the Goldstone sector of a well-motivated extension of the Littlest Higgs with T-parity. A viable parameter space, consistent with the observed dark matter relic abundance as well as with the various collider, electroweak precision and dark matter direct detection experimental constraints is found for this scenario. T-parity implies a rich LHC phenomenology, which forms an interesting interplay between conventional natural SUSY type of signals involving third generation quarks and missing energy, from stop-like particle production and decay, and composite Higgs type of signals involving third generation quarks associated with Higgs and electroweak gauge boson, from vector like top-partners production and decay. The composite features of the dark matter phenomenology allows the composite singlet to produce the correct relic abundance while interacting weakly with the Higgs via the usual Higgs portal coupling [Formula: see text], thus evading direct detection. PMID- 29445314 TI - Prognostic assessment for patients with cancer and incidental pulmonary embolism. AB - Background: An incidental/unsuspected diagnosis of pulmonary embolism (IPE) in cancer patients is a frequent occurrence. This single-institution analysis of uniformly managed patients investigates short and long-term outcomes and proposes a prognostic risk score, aiming to assist clinical decision-making. Methods: Data from a prospectively recorded cohort of 234 consecutive cancer patients with IPE were analysed. Multivariate logistic regression and the Cox regression survival methods were used to identify factors with independent association with early (30 day, 3-month, 6-month) mortality and survival. Receiver operator characteristic analysis (ROC) was used to assess appropriate cut-offs for continuous variables and the fitness of prognostic scoring. Results: 30-day, 3-month and 6-month mortality was 3.4% (n = 8), 15% (n = 35) and 31% (n = 72) respectively. Recurrence during anticoagulation occurred in 2.6% (n = 6) and major haemorrhage in 2.1% (n = 5) of the patients. A prognostic score incorporating performance status (0 vs 1-2 vs 3-4) and the presence of new or worsening symptoms, with and without the consideration of the presence of incurable malignancy, correlated with overall survival (p < .001 respectively) as well as early mortality (AUC = .821, p = .004 and AUC = .805, p = 0.006, respectively). Conclusion: A simple prognostic score incorporating basic oncologic clinical assessment and self reported symptomatology could reliably stratify the mortality risk of ambulant cancer patients and IPE.

PMID- 29445315 TI - Surfaces with Controllable Topography and Chemistry Used as a Template for Protein Crystallization. AB - Surfaces with controllable topography and chemistry were prepared to act as substrates for protein crystallization, in order to investigate the influence of these surface properties on the protein crystallization outcome. Three different methods were investigated to deposit 1,3,5-tris(10-carboxydecyloxy)benzene (TCDB) on a muscovite mica substrate to find the best route for controlled topography. Of these three, sublimation worked best. Contact angle measurements revealed that the surfaces with short exposure to the TCDB vapor (20 min or less) are hydrophilic, while surfaces exposed for 30 min or longer are hydrophobic. The hydrophilic surfaces are flat with low steps, while the hydrophobic surfaces contain macrosteps. Four model proteins were used for crystallization on the surfaces with controlled topography and chemistry. Hen egg white lysozyme crystals were less numerous on the surface with macrosteps than on smoother surfaces. On the other hand, insulin nucleated faster on the hydrophobic surfaces with macrosteps, and therefore, the crystals were more abundant and smaller. Bovine serum albumin and talin protein crystals were more numerous on all TCDB functionalized surfaces, compared to the reference clean muscovite mica surfaces. Overall, this shows that surface topography and chemistry is an important factor that partly determines the outcome in a protein crystallization experiment. PMID- 29445316 TI - Evaluating the Energetic Driving Force for Cocrystal Formation. AB - We present a periodic density functional theory study of the stability of 350 organic cocrystals relative to their pure single-component structures, the largest study of cocrystals yet performed with high-level computational methods. Our calculations demonstrate that cocrystals are on average 8 kJ mol-1 more stable than their constituent single-component structures and are very rarely (<5% of cases) less stable; cocrystallization is almost always a thermodynamically favorable process. We consider the variation in stability between different categories of systems-hydrogen-bonded, halogen-bonded, and weakly bound cocrystals-finding that, contrary to chemical intuition, the presence of hydrogen or halogen bond interactions is not necessarily a good predictor of stability. Finally, we investigate the correlation of the relative stability with simple chemical descriptors: changes in packing efficiency and hydrogen bond strength. We find some broad qualitative agreement with chemical intuition-more densely packed cocrystals with stronger hydrogen bonding tend to be more stable-but the relationship is weak, suggesting that such simple descriptors do not capture the complex balance of interactions driving cocrystallization. Our conclusions suggest that while cocrystallization is often a thermodynamically favorable process, it remains difficult to formulate general rules to guide synthesis, highlighting the continued importance of high-level computation in predicting and rationalizing such systems. PMID- 29445317 TI - Resolving Crystallization Kinetics of GeTe Phase-Change Nanoparticles by Ultrafast Calorimetry. AB - Chalcogenide-based phase change materials (PCMs) are promising candidates for the active element in novel electrical nonvolatile memories and have been applied successfully in rewritable optical disks. Nanostructured PCMs are considered as the next generation building blocks for their low power consumption, high storage density, and fast switching speed. Yet their crystallization kinetics at high temperature, the rate-limiting property upon switching, faces great challenges due to the short time and length scales involved. Here we present a facile method to synthesize highly controlled, ligand-free GeTe nanoparticles, an important PCM, with an average diameter under 10 nm. Subsequent crystallization by slow and ultrafast rates allows unravelling of the crystallization kinetics, demonstrating the breakdown of Arrhenius behavior for the crystallization rate and a fragile-to strong transition in the viscosity as well as the overall crystal growth rate for the as-deposited GeTe nanoparticles. The obtained results pave the way for further development of phase-change memory based on GeTe with sub-lithographic sizes. PMID- 29445318 TI - Inhibition of the Vapor-Mediated Phase Transition of the High Temperature Form of Pyrazinamide. AB - Tailor-made additives can prove an effective method to prolong the lifetime of metastable forms of pharmaceutical compounds by surface stabilization. Pyrazinamide (PZA) is a pharmaceutical compound with four polymorphic forms. The high temperature gamma form, which can be produced by spray drying or sublimation growth, is metastable at room temperature and transforms within days when produced by spray drying, and within several months up to years for single crystals produced by sublimation. However, when PZA is cospray dried with 1,3 dimethylurea (DMU), it has been reported to remain in its gamma form for several years. Scanning electron microscopy (SEM) images reveal that the phase transition from gamma-PZA to the low temperature forms involves a vapor-mediated recrystallization, while the reverse phase transition upon heating is a nucleation-and-growth solid-solid phase transition. The lifetime-extending effect of DMU on spray-dried PZA has been investigated in more detail and compared with high-energy ball milling of sublimation-grown gamma-PZA crystals. Co-ball milling of PZA and DMU is found to extend the lifetime of the high temperature form of PZA to a few months, while separate ball milling leads to an extension of merely a few weeks. DMU acts as an additive that most likely stabilizes the surface of gamma-PZA, which would reduce the vapor pressure of PZA, thereby reducing the transition rate. Alternatively, DMU could prevent nucleation of low temperature forms of PZA. PMID- 29445319 TI - Quantifying the uptake of user-written commands over time. AB - A major factor in the uptake of new statistical methods is the availability of user-friendly software implementations. One attractive feature of Stata is that users can write their own commands and release them to other users via Statistical Software Components at Boston College. Authors of statistical programs do not always get adequate credit, because programs are rarely cited properly. There is no obvious measure of a program's impact, but researchers are under increasing pressure to demonstrate the impact of their work to funders. In addition to encouraging proper citation of software, the number of downloads of a user-written package can be regarded as a measure of impact over time. In this article, we explain how such information can be accessed for any month from July 2007 and summarized using the new ssccount command. PMID- 29445320 TI - A combined test for a generalized treatment effect in clinical trials with a time to-event outcome. AB - Most randomized controlled trials with a time-to-event outcome are designed and analyzed assuming proportional hazards of the treatment effect. The sample-size calculation is based on a log-rank test or the equivalent Cox test. Nonproportional hazards are seen increasingly in trials and are recognized as a potential threat to the power of the log-rank test. To address the issue, Royston and Parmar (2016, BMC Medical Research Methodology 16: 16) devised a new "combined test" of the global null hypothesis of identical survival curves in each trial arm. The test, which combines the conventional Cox test with a new formulation, is based on the maximal standardized difference in restricted mean survival time (rmst) between the arms. The test statistic is based on evaluations of rmst over several preselected time points. The combined test involves the minimum p-value across the Cox and rmst-based tests, appropriately standardized to have the correct null distribution. In this article, I outline the combined test and introduce a command, stctest, that implements the combined test. I point the way to additional tools currently under development for power and sample-size calculation for the combined test. PMID- 29445321 TI - Gallium-68 Labeled Iron Oxide Nanoparticles Coated with 2,3-Dicarboxypropane-1,1 diphosphonic Acid as a Potential PET/MR Imaging Agent: A Proof-of-Concept Study. AB - The aim of this study was to develop a dual-modality PET/MR imaging probe by radiolabeling iron oxide magnetic nanoparticles (IONPs), surface functionalized with water soluble stabilizer 2,3-dicarboxypropane-1,1-diphosphonic acid (DPD), with the positron emitter Gallium-68. Magnetite nanoparticles (Fe3O4 MNPs) were synthesized via coprecipitation method and were stabilized with DPD. The Fe3O4 DPD MNPs were characterized based on their structure, morphology, size, surface charge, and magnetic properties. In vitro cytotoxicity studies showed reduced toxicity in normal cells, compared to cancer cells. Fe3O4-DPD MNPs were successfully labeled with Gallium-68 at high radiochemical purity (>91%) and their stability in human serum and in PBS was demonstrated, along with their further characterization on size and magnetic properties. The ex vivo biodistribution studies in normal Swiss mice showed high uptake in the liver followed by spleen. The acquired PET images were in accordance with the ex vivo biodistribution results. Our findings indicate that 68Ga-Fe3O4-DPD MNPs could serve as an important diagnostic tool for biomedical imaging. PMID- 29445322 TI - The Impact of Novel Radiation Treatment Techniques on Toxicity and Clinical Outcomes In Rectal Cancer. AB - Purpose of review: Three-dimensional conformal radiation therapy (3DCRT) has been the standard technique in the treatment of rectal cancer. The use of new radiation treatment technologies such as intensity-modulated radiation therapy (IMRT), proton therapy (PT), stereotactic body radiation therapy (SBRT) and brachytherapy (BT) has been increasing over the past 10 years. This review will highlight the advantages and drawbacks of these techniques. Recent findings: IMRT, PT, SBRT and BT achieve a higher target coverage conformity, a higher organ at risk sparing and enable dose escalation compared to 3DCRT. Some studies suggested a reduction in gastrointestinal and hematologic toxicities and an increase in the complete pathologic response rate; however, the clinical benefit of these techniques remains controversial. Summary: The results of these new techniques seem encouraging despite conclusive data. Further trials are required to establish their role in rectal cancer. PMID- 29445323 TI - Urine proteomics of primary membranous nephropathy using nanoscale liquid chromatography tandem mass spectrometry analysis. AB - Background: Primary membranous nephropathy (PMN) is an important cause of nephrotic syndrome in adults. Urine proteome may provide important clues of pathophysiological mechanisms in PMN. In the current study, we analyzed and compared the proteome of urine from patients with PMN and normal controls. Methods: We performed two technical replicates (TMT1 and TMT2) to analyze and compare the urine proteome from patients with PMN and normal controls by tandem mass tag (TMT) technology coupled with nanoscale liquid chromatography tandem mass spectrometry analysis (LC-MS/MS). Gene ontology (GO) enrichment analysis was performed to analyse general characterization of the proteins. The proteins were also matched against the database of Kyoto Encyclopedia of Genes and Genomes (KEGG). For validation, Western blot was used to analyze the selected proteins. Results: A total of 509 proteins and 411 proteins were identified in TMT1 and TMT2, respectively. 249 proteins were both identified in two technical replicates. GO analysis and KEGG analysis revealed immunization and coagulation were predominantly involved. Among the differential protein, the overexcretion of alpha-1-antitrypsin (A1AT) and afamin (AFM) were validated by Western blot analysis. Conclusions: Our data showed the important role of immunologic mechanism in the development of PMN, and the value of urinary A1AT and AFM in biomarker discovery of patients with PMN. The discovery of the overexcretion of A1AT and AFM in the urine can help to further elucidate pathogenetic mechanisms involved in PMN. PMID- 29445324 TI - Delayed Degradation and Impaired Dendritic Delivery of Intron-Lacking EGFP Arc/Arg3.1 mRNA in EGFP-Arc Transgenic Mice. AB - Arc is a unique immediate early gene (IEG) whose expression is induced as synapses are modified during learning. Newly-synthesized Arc mRNA is rapidly transported throughout dendrites and localizes near recently activated synapses. Arc mRNA levels are regulated by rapid degradation, which is accelerated by synaptic activity in a translation-dependent process. One possible mechanism is nonsense-mediated mRNA decay (NMD), which depends on the presence of a splice junction in the 3'UTR. Here, we test this hypothesis using transgenic mice that express EGFP-Arc. Because the transgene was constructed from Arc cDNA, it lacks intron structures in the 3'UTR that are present in the endogenous Arc gene. NMD depends on the presence of proteins of the exon junction complex (EJC) downstream of a stop codon, so EGFP-Arc mRNA should not undergo NMD. Assessment of Arc mRNA rundown in the presence of the transcription inhibitor actinomycin-D confirmed delayed degradation of EGFP-Arc mRNA. EGFP-Arc mRNA and protein are expressed at much higher levels in transgenic mice under basal and activated conditions but EGFP-Arc mRNA does not enter dendrites efficiently. In a physiological assay in which cycloheximide (CHX) was infused after induction of Arc by seizures, there were increases in endogenous Arc mRNA levels consistent with translation dependent Arc mRNA decay but this was not seen with EGFP-Arc mRNA. Taken together, our results indicate: (1) Arc mRNA degradation occurs via a mechanism with characteristics of NMD; (2) rapid dendritic delivery of newly synthesized Arc mRNA after induction may depend in part on prior splicing of the 3'UTR. PMID- 29445325 TI - Biomarkers of Amyotrophic Lateral Sclerosis: Current Status and Interest of Oxysterols and Phytosterols. AB - Amyotrophic lateral sclerosis (ALS) is a non-demyelinating neurodegenerative disease in adults with motor disorders. Two forms exist: a sporadic form (90% of cases) and a family form due to mutations in more than 20 genes including the Superoxide dismutase 1, TAR DNA Binding Protein, Fused in Sarcoma, chromosome 9 open reading frame 72 and VAPB genes. The mechanisms associated with this pathology are beginning to be known: oxidative stress, glutamate excitotoxicity, protein aggregation, reticulum endoplasmic stress, neuroinflammation, alteration of RNA metabolism. In various neurodegenerative diseases, such as Alzheimer's disease or multiple sclerosis, the involvement of lipids is increasingly suggested based on lipid metabolism modifications. With regard to ALS, research has also focused on the possible involvement of lipids. Lipid involvement was suggested for clinical arguments where changes in cholesterol and LDL/HDL levels were reported with, however, differences in positivity between studies. Since lipids are involved in the membrane structure and certain signaling pathways, it may be considered to look for oxysterols, mainly 25-hydroxycholesterol and its metabolites involved in immune response, or phytosterols to find suitable biomarkers for this pathology. PMID- 29445326 TI - Structure/Function Studies of the alpha4 Subunit Reveal Evolutionary Loss of a GlyR Subtype Involved in Startle and Escape Responses. AB - Inhibitory glycine receptors (GlyRs) are pentameric ligand-gated anion channels with major roles in startle disease/hyperekplexia (GlyR alpha1), cortical neuronal migration/autism spectrum disorder (GlyR alpha2), and inflammatory pain sensitization/rhythmic breathing (GlyR alpha3). However, the role of the GlyR alpha4 subunit has remained enigmatic, because the corresponding human gene (GLRA4) is thought to be a pseudogene due to an in-frame stop codon at position 390 within the fourth membrane-spanning domain (M4). Despite this, a recent genetic study has implicated GLRA4 in intellectual disability, behavioral problems and craniofacial anomalies. Analyzing data from sequenced genomes, we found that GlyR alpha4 subunit genes are predicted to be intact and functional in the majority of vertebrate species-with the exception of humans. Cloning of human GlyR alpha4 cDNAs excluded alternative splicing and RNA editing as mechanisms for restoring a full-length GlyR alpha4 subunit. Moreover, artificial restoration of the missing conserved arginine (R390) in the human cDNA was not sufficient to restore GlyR alpha4 function. Further bioinformatic and mutagenesis analysis revealed an additional damaging substitution at K59 that ablates human GlyR alpha4 function, which is not present in other vertebrate GlyR alpha4 sequences. The substitutions K59 and X390 were also present in the genome of an ancient Denisovan individual, indicating that GLRA4 has been a pseudogene for at least 30,000-50,000 years. In artificial synapses, we found that both mouse and gorilla alpha4beta GlyRs mediate synaptic currents with unusually slow decay kinetics. Lastly, to gain insights into the biological role of GlyR alpha4 function, we studied the duplicated genes glra4a and glra4b in zebrafish. While glra4b expression is restricted to the retina, using a novel tol2-GAL4FF gene trap line (SAIGFF16B), we found that the zebrafish GlyR alpha4a subunit gene (glra4a) is strongly expressed in spinal cord and hindbrain commissural neurones. Using gene knockdown and a dominant-negative GlyR alpha4aR278Q mutant, we found that GlyR alpha4a contributes to touch-evoked escape behaviors in zebrafish. Thus, although GlyR alpha4 is unlikely to be involved in human startle responses or disease states, this subtype may contribute to escape behaviors in other organisms. PMID- 29445327 TI - Missense Gamma-Aminobutyric Acid Receptor Polymorphisms Are Associated with Reaction Time, Motor Time, and Ethanol Effects in Vivo. AB - Background: The Gamma-aminobutyric acid type A receptor (GABA-A receptor) is affected by ethanol concentrations equivalent to those reached during social drinking. At these concentrations, ethanol usually causes impairment in reaction and motor times in most, but not all, individuals. Objectives: To study the effect of GABA-A receptor variability in motor and reaction times, and the effect of low ethanol doses. Methods: Two hundred and fifty healthy subjects received one single dose of 0.5 g/Kg ethanol per os. Reaction and motor times were determined before ethanol challenge (basal), and when participants reached peak ethanol concentrations. We analyzed all common missense polymorphisms described in the 19 genes coding for the GABA-A receptor subunits by using TaqMan probes. Results: The GABRA6 rs4454083 T/C polymorphisms were related to motor times, with individuals carrying the C/C genotype having faster motor times, both, at basal and at peak ethanol concentrations. The GABRA4 rs2229940 T/T genotype was associated to faster reaction times and with lower ethanol effects, determined as the difference between basal reaction time and reaction time at peak concentrations. All these associations remained significant after correction for multiple comparisons. No significant associations were observed for the common missense SNPs GABRB3 rs12910925, GABRG2 rs211035, GABRE rs1139916, GABRP rs1063310, GABRQ rs3810651, GABRR1 rs12200969 or rs1186902, GABRR2 rs282129, and GABRR3 rs832032. Conclusions: This study provides novel information supporting a role of missense GABA-A receptor polymorphisms in reaction time, motor time and effects of low ethanol doses in vivo. PMID- 29445328 TI - Hippocampal Atrophy Following Subarachnoid Hemorrhage Correlates with Disruption of Astrocyte Morphology and Capillary Coverage by AQP4. AB - Despite successful management of ruptured intracranial aneurysm following subarachnoid hemorrhage (SAH), delayed cerebral ischemia (DCI) remains the main cause of high mortality and morbidity in patients who survive the initial bleeding. Astrocytes play a key role in neurovascular coupling. Therefore, changes in the neurovascular unit including astrocytes following SAH may contribute to the development of DCI and long-term complications. In this study, we characterized morphological changes in hippocampal astrocytes following experimental SAH, with special emphasis on glia-vascular cross-talk and hippocampal volume changes. Four days after induction of SAH or sham-operation in mice, their hippocampal volumes were determined by magnetic resonance imaging (MRI) and histological/stereological methods. Glial fibrillary acid protein (GFAP) immunostained hippocampal sections were examined by stereological techniques to detect differences in astrocyte morphology, and global spatial sampling method was used to quantify the length density of Aquaporin-4 (AQP4) positive capillaries. Our results indicated that hippocampal volume, as measured both by MRI and by histological approaches, was significantly lower in SAH animals than in the sham-operated group. Accordingly, in this animal model of SAH, hippocampal atrophy existed already at the time of DCI onset in humans. SAH induced retraction of GFAP positive astrocyte processes, accompanied by a significant reduction in the length density of AQP4 positive capillaries as well as narrowing of hippocampal capillaries. Meanwhile, astrocyte volume was higher in SAH mice compared with the sham-operated group. Morphological changes in hippocampal astrocytes seemingly disrupt glia-vascular interactions early after SAH and may contribute to hippocampal atrophy. We speculate that astrocytes and astrocyte-capillary interactions may provide targets for the development of therapies to improve the prognosis of SAH. PMID- 29445329 TI - The Effects of Transcranial Direct Current Stimulation (tDCS) on Psychomotor and Visual Perception Functions Related to Driving Skills. AB - Objective: It could be demonstrated that anodal transcranial direct current stimulation (tDCS) of the left dorsolateral prefrontal cortex (DLPFC) enhances accuracy in working memory tasks and reaction time in healthy adults and thus may also have an influence on complex everyday tasks like driving a car. However, no studies have applied tDCS to psychomotor skills related to a standard driving test so far. Methods: 10 female and 5 male healthy adults without any medication and history of psychiatric or neurological illness were randomly assigned to two groups receiving active and sham stimulation in a double blind, cross-over study design. Standardized computerized psychomotor tests according to the German guidelines for road and traffic safety were administered at baseline. Then they performed the same tests during an anodal or sham tDCS of the left DLPFC in two separated sessions. Results: No significant improvements in skills related to driving performance like visual perception, stress tolerance, concentration, and vigilance could be shown after left anodal prefrontal tDCS. Side effects were low and did not differ between active and sham stimulation. Conclusions: The findings of our study indicate that left prefrontal tDCS may not alter driving skills affording more automated action patterns but as shown in previous studies may have an influence on driving behavior requiring executive control processes. This however has to be proved in future studies and within greater samples. PMID- 29445330 TI - Non-neural Muscle Weakness Has Limited Influence on Complexity of Motor Control during Gait.

Weakness in CP has neural and non neural components, whereas in DMD, weakness can be considered as a predominantly non-neural problem. Despite the different underlying causes, weakness is a constraint for the central nervous system when controlling gait. CP demonstrates decreased complexity of motor control during gait from muscle synergy analysis, which is reflected by a higher total variance accounted for by one synergy (tVAF1). However, it remains unclear if weakness directly contributes to higher tVAF1 in CP, or whether altered tVAF1 reflects mainly neural impairments. If muscle weakness directly contributes to higher tVAF1, then tVAF1 should also be increased in DMD. To examine the etiology of increased tVAF1, muscle activity data of gluteus medius, rectus femoris, medial hamstrings, medial gastrocnemius, and tibialis anterior were measured at self-selected walking speed, and strength data from knee extensors, knee flexors, dorsiflexors and plantar flexors, were analyzed in 15 children with CP [median (IQR) age: 8.9 (2.2)], 15 boys with DMD [8.7 (3.1)], and 15 typical developing (TD) children [8.6 (2.7)]. We computed tVAF1 from 10 concatenated steps with non-negative matrix factorization, and compared tVAF1 between the three groups with a Mann-Whiney U-test. Spearman's rank correlation coefficients were used to determine if weakness in specific muscle groups contributed to altered tVAF1. No significant differences in tVAF1 were found between DMD [tVAF1: 0.60 (0.07)] and TD children [0.65 (0.07)], while tVAF1 was significantly higher in CP [(0.74 (0.09)] than in the other groups (both p < 0.005). In CP, weakness in the plantar flexors was related to higher tVAF1 (r = -0.72). In DMD, knee extensor weakness related to increased tVAF1 (r = -0.50). These results suggest that the non-neural weakness in DMD had limited influence on complexity of motor control during gait and that the higher tVAF1 in children with CP is mainly related to neural impairments caused by the brain lesion. PMID- 29445331 TI - Do Event-Related Evoked Potentials Reflect Apathy Tendency and Motivation? AB - Apathy is a mental state of diminished motivation. Although the reward system as the foundation of the motivation in the human brain has been studied extensively with neuroimaging techniques, the electrophysiological correlates of motivation and apathy have not been fully explored. Thus, in 14 healthy volunteers, we examined whether event-related evoked potentials (ERP) obtained during a simple number discrimination task with/without rewards reflected apathy tendency and a reward-dependent tendency, which were assessed separately using the apathy scale and the temperament and character inventory (TCI). Participants were asked to judge the size of a number, and received feedback based on their performance in each trial. The P3 amplitudes related to the feedback stimuli increased only in the reward condition. Furthermore, the P2 amplitudes related to the negative feedback stimuli in the reward condition had a positive correlation with the reward-dependent tendency in TCI, whereas the P3 amplitudes related to the positive feedback stimuli had a negative correlation with the apathy score. Our result suggests that the P2 and P3 ERPs to reward-related feedback stimuli are modulated in a distinctive manner by the motivational reward dependence and apathy tendency, and thus the current paradigm may be useful for investigating the brain activity associated with motivation. PMID- 29445332 TI - Motor Unit Action Potential Clustering-Theoretical Consideration for Muscle Activation during a Motor Task. AB - During dynamic or sustained isometric contractions, bursts of muscle activity appear in the electromyography (EMG) signal. Theoretically, these bursts of activity likely occur because motor units are constrained to fire temporally close to one another and thus the impulses are "clustered" with short delays to elicit bursts of muscle activity. The purpose of this study was to investigate whether a sequence comprised of "clustered" motor unit action potentials (MUAP) can explain spectral and amplitude changes of the EMG during a simulated motor task. This question would be difficult to answer experimentally and thus, required a model to study this type of muscle activation pattern. To this end, we modeled two EMG signals, whereby a single MUAP was either convolved with a randomly distributed impulse train (EMG-rand) or a "clustered" sequence of impulses (EMG-clust). The clustering occurred in windows lasting 5-100 ms. A final mixed signal of EMG-clust and EMG-rand, with ratios (1:1-1:10), was also modeled. A ratio of 1:1 would indicate that 50% of MUAP were randomly distributed, while 50% of "clustered" MUAP occurred in a given time window (5-100 ms). The results of the model showed that clustering MUAP caused a downshift in the mean power frequency (i.e., ~30 Hz) with the largest shift occurring with a cluster window of 10 ms. The mean frequency shift was largest when the ratio of EMG-clust to EMG-rand was high. Further, the clustering of MUAP also caused a substantial increase in the amplitude of the EMG signal. This model potentially explains an activation pattern that changes the EMG spectra during a motor task and thus, a potential activation pattern of muscles observed experimentally. Changes in EMG measurements during fatiguing conditions are typically attributed to slowing of conduction velocity but could, per this model, also result from changes of the clustering of MUAP. From a clinical standpoint, this type of muscle activation pattern might help describe the pathological movement issues in people with Parkinson's disease or essential tremor. Based on our model, researchers moving forward should consider how MUAP clustering influences EMG spectral and amplitude measurements and how these changes influence movements. PMID- 29445334 TI - Post-task Effects on EEG Brain Activity Differ for Various Differential Learning and Contextual Interference Protocols. AB - A large body of research has shown superior learning rates in variable practice compared to repetitive practice. More specifically, this has been demonstrated in the contextual interference (CI) and in the differential learning (DL) approach that are both representatives of variable practice. Behavioral studies have indicate different learning processes in CI and DL. Aim of the present study was to examine immediate post-task effects on electroencephalographic (EEG) brain activation patterns after CI and DL protocols that reveal underlying neural processes at the early stage of motor consolidation. Additionally, we tested two DL protocols (gradual DL, chaotic DL) to examine the effect of different degrees of stochastic fluctuations within the DL approach with a low degree of fluctuations in gradual DL and a high degree of fluctuations in chaotic DL. Twenty-two subjects performed badminton serves according to three variable practice protocols (CI, gradual DL, chaotic DL), and a repetitive learning protocol in a within-subjects design. Spontaneous EEG activity was measured before, and immediately after each 20-min practice session from 19 electrodes. Results showed distinguishable neural processes after CI, DL, and repetitive learning. Increases in EEG theta and alpha power were obtained in somatosensory regions (electrodes P3, P7, Pz, P4, P8) in both DL conditions compared to CI, and repetitive learning. Increases in theta and alpha activity in motor areas (electrodes C3, Cz, C4) were found after chaotic DL compared to gradual DL, and CI. Anterior areas (electrodes F3, F7, Fz, F4, F8) showed increased activity in the beta and gamma bands after CI. Alpha activity was increased in occipital areas (electrodes O1, O2) after repetitive learning. Post-task EEG brain activation patterns suggest that DL stimulates the somatosensory and motor system, and engages more regions of the cortex than repetitive learning due to a tighter stimulation of the motor and somatosensory system during DL practice. CI seems to activate specifically executively controlled processing in anterior brain areas. We discuss the obtained patterns of post-training EEG traces as evidence for different underlying neural processes in CI, DL, and repetitive learning at the early stage of motor learning. PMID- 29445333 TI - Sleep-Dependent Memory Consolidation and Incremental Sentence Comprehension: Computational Dependencies during Language Learning as Revealed by Neuronal Oscillations. AB - We hypothesize a beneficial influence of sleep on the consolidation of the combinatorial mechanisms underlying incremental sentence comprehension. These predictions are grounded in recent work examining the effect of sleep on the consolidation of linguistic information, which demonstrate that sleep-dependent neurophysiological activity consolidates the meaning of novel words and simple grammatical rules. However, the sleep-dependent consolidation of sentence-level combinatorics has not been studied to date. Here, we propose that dissociable aspects of sleep neurophysiology consolidate two different types of combinatory mechanisms in human language: sequence-based (order-sensitive) and dependency based (order-insensitive) combinatorics. The distinction between the two types of combinatorics is motivated both by cross-linguistic considerations and the neurobiological underpinnings of human language. Unifying this perspective with principles of sleep-dependent memory consolidation, we posit that a function of sleep is to optimize the consolidation of sequence-based knowledge (the when) and the establishment of semantic schemas of unordered items (the what) that underpin cross-linguistic variations in sentence comprehension. This hypothesis builds on the proposal that sleep is involved in the construction of predictive codes, a unified principle of brain function that supports incremental sentence comprehension. Finally, we discuss neurophysiological measures (EEG/MEG) that could be used to test these claims, such as the quantification of neuronal oscillations, which reflect basic mechanisms of information processing in the brain. PMID- 29445335 TI - Dual-Tasking in Multiple Sclerosis - Implications for a Cognitive Screening Instrument. AB - The monitoring of cognitive functions is central to the assessment and consecutive management of multiple sclerosis (MS). Though, especially cognitive processes that are central to everyday behavior like dual-tasking are often neglected. We examined dual-task performance using a psychological-refractory period (PRP) task in N = 21 patients and healthy controls and conducted standard neuropsychological tests. In dual-tasking, MS patients committed more erroneous responses when dual-tasking was difficult. In easier conditions, performance of MS patients did not differ to controls. Interestingly, the response times were generally not affected by the difficulty of the dual task, showing that the deficits observed do not reflect simple motor deficits or deficits in information processing speed but point out deficits in executive control functions and response selection in particular. Effect sizes were considerably large with d~0.80 in mild affected patients and the achieved power was above 99%. There are cognitive control and dual tasking deficits in MS that are not attributable to simple motor speed deficits. Scaling of the difficulty of dual-tasking makes the test applied suitable for a wide variety of MS-patients and may complement neuropsychological assessments in clinical care and research setting. PMID- 29445336 TI - The Two-Systems Account of Theory of Mind: Testing the Links to Social- Perceptual and Cognitive Abilities. AB - According to the two-systems account of theory of mind (ToM), understanding mental states of others involves both fast social-perceptual processes, as well as slower, reflexive cognitive operations (Frith and Frith, 2008; Apperly and Butterfill, 2009). To test the respective roles of specific abilities in either of these processes we administered 15 experimental procedures to a large sample of 343 participants, testing ability in face recognition and holistic perception, language, and reasoning. ToM was measured by a set of tasks requiring ability to track and to infer complex emotional and mental states of others from faces, eyes, spoken language, and prosody. We used structural equation modeling to test the relative strengths of a social-perceptual (face processing related) and reflexive-cognitive (language and reasoning related) path in predicting ToM ability. The two paths accounted for 58% of ToM variance, thus validating a general two-systems framework. Testing specific predictor paths revealed language and face recognition as strong and significant predictors of ToM. For reasoning, there were neither direct nor mediated effects, albeit reasoning was strongly associated with language. Holistic face perception also failed to show a direct link with ToM ability, while there was a mediated effect via face recognition. These results highlight the respective roles of face recognition and language for the social brain, and contribute closer empirical specification of the general two-systems account. PMID- 29445339 TI - Population Pharmacokinetic Modeling of a Desmopressin Oral Lyophilisate in Growing Piglets as a Model for the Pediatric Population. AB - Desmopressin is used to treat primary nocturnal enuresis in children. Over the years, various formulations of desmopressin were commercialized of which the sublingual melt tablet is preferred in the pediatric population, despite the lack of full PK studies in this population. A full PK study was performed in growing conventional piglets to evaluate if this juvenile animal model can provide supplementary information to complement the information gap in the pediatric population. A desmopressin sublingual melt tablet (120 MUg) was administered to 32 male piglets aged 8 days, 4 weeks, 7 weeks, and 6 months (each group n = 8). Population PK (pop-PK) analysis was performed to derive the PK parameters, the between- and within-subject variabilities and the effects of covariates. Desmopressin demonstrated two-compartmental PK, with a dual, sequential absorption process, and linear elimination. Body weight was the only significant covariate on clearance and on apparent volume of distribution of the central compartment. In human pediatric trials, no double peak in the absorption phase was observed in the plasma concentration-time curves, possibly due to the sparse sampling strategy applied in those pediatric studies. Therefore, it is recommended to perform additional studies, based on the sampling protocol applied in the current study. PMID- 29445337 TI - Cocaine-Induced Changes in Low-Dimensional Attractors of Local Field Potentials in Optogenetic Mice. AB - Optogenetically evoked local field potential (LFP) recorded from the medial prefrontal cortex (mPFC) of mice during basal conditions and following a systemic cocaine administration were analyzed. Blue light stimuli were delivered to mPFC through a fiber optic every 2 s and each trial was repeated 100 times. As in the previous study, we used a surrogate data method to check that nonlinearity was present in the experimental LFPs and only used the last 1.5 s of steady activity to measure the LFPs phase resetting induced by the brief 10 ms light stimulus. We found that the steady dynamics of the mPFC in response to light stimuli could be reconstructed in a three-dimensional phase space with topologically similar "8" shaped attractors across different animals. Therefore, cocaine did not change the complexity of the recorded nonlinear data compared to the control case. The phase space of the reconstructed attractor is determined by the LFP time series and its temporally shifted versions by a multiple of some lag time. We also compared the change in the attractor shape between cocaine-injected and control using (1) dendrogram clustering and (2) Frechet distance. We found about 20% overlap between control and cocaine trials when classified using dendrogram method, which suggest that it may be possible to describe mathematically both data sets with the same model and slightly different model parameters. We also found that the lag times are about three times shorter for cocaine trials compared to control. As a result, although the phase space trajectories for control and cocaine may look similar, their dynamics is significantly different. PMID- 29445338 TI - Synaptic Homeostasis and Allostasis in the Dentate Gyrus Caused by Inflammatory and Neuropathic Pain Conditions. AB - It has been generally accepted that pain can cause imbalance between excitation and inhibition (homeostasis) at the synaptic level. However, it remains poorly understood how this imbalance (allostasis) develops in the CNS under different pain conditions. Here, we analyzed the changes in both excitatory and inhibitory synaptic transmission and modulation of the dentate gyrus (DG) under two pain conditions with different etiology and duration. First, it was revealed that the functions of the input-output (I/O) curves for evoked excitatory postsynaptic currents (eEPSCs) following the perforant path (PP) stimulation were gained under both acute inflammatory and chronic neuropathic pain conditions relative to the controls. However, the functions of I/O curves for the PP-evoked inhibitory postsynaptic currents (eIPSCs) differed between the two conditions, namely it was greatly gained under inflammatory condition, but was reduced under neuropathic condition in reverse. Second, both the frequency and amplitude of miniature IPSCs (mIPSCs) were increased under inflammatory condition, however a decrease in frequency of mIPSCs was observed under neuropathic condition. Finally, the spike discharge of the DG granule cells in response to current injection was significantly increased by neuropathic pain condition, however, no different change was found between inflammatory pain condition and the control. These results provide another line of evidence showing homeostatic and allostatic modulation of excitatory synaptic transmission by inhibitory controls under different pathological pain conditions, hence implicating use of different therapeutic approaches to maintain the homeostasis between excitation and inhibition while treating different conditions of pathological pain. PMID- 29445340 TI - Inhibition of Glucose-6-Phosphate Dehydrogenase Reverses Cisplatin Resistance in Lung Cancer Cells via the Redox System. AB - The pentose phosphate pathway (PPP), which branches from glycolysis, is correlated with cancer cell proliferation, survival and senescence. In this study, differences in the metabolic profile of the PPP and the redox status of human lung carcinoma A549 cells and cisplatin-induced multidrug-resistant A549/DDP cells were analyzed and evaluated. The results showed that A549/DDP cells exhibited differential PPP-derived metabolic features and redox-related molecules. A549/DDP cells exhibited increased expression and enzymatic activity of PPP enzyme glucose-6-phosphate dehydrogenase (G6PD). Furthermore, as demonstrated by the apoptotic rate, cell viability, and colony formation, inhibition of G6PD by siRNA or an inhibitor sensitized A549/DDP cells to cisplatin. Additionally, inhibition of G6PD restored the cisplatin sensitivity of A549/DDP cells by influencing redox homeostasis. In conclusion, overcoming cisplatin resistance through inhibition of G6PD could improve the understanding of the mechanisms underlying cisplatin-induced resistance in human lung cancer and may provide insights into the therapeutic potential of this treatment to combat resistance. PMID- 29445341 TI - Celastrol Alleviates Airway Hyperresponsiveness and Inhibits Th17 Responses in Obese Asthmatic Mice. AB - Severe airway hyperresponsiveness (AHR) is a clinical feature of asthma, which has been associated with obesity and has shown a poor response to standard asthma treatments such as glucocorticoids. Numerous studies have shown that Interleukin (IL)-17 producing CD4+T cells (Th17 cells), which could be inhibited by celastrol, is essential in mediating steroid-resistant AHR. The following study investigates the impact of celastrol and its mechanism on the regulation of AHR in murine model of obesity and asthma. C57BL/6 mice were sensitized by intraperitoneal injection of ovalbumin (OVA) on day 1 and 13 starting from 12th week, which was followed by aerosol OVA challenge that lasted for 30 min per daily for 7 consecutive days starting from 16th week. Diet-induced obesity (DIO) mice were fed a high fat diet (HFD) for 16 weeks. Celastrol was administrated orally for 7 consecutive days, 30 min before every challenge in DIO-OVA-induced mice. Lung functions were analyzed by measuring the airway resistance (Rn) and methacholine (MCh) AHR, while H&E staining was used to examine histological changes in the lungs. Immunohistochemistry was used to observe IL-17A protein in lung tissues; flow cytometry to detect the proportion of Th17 cells in CD4+T cells. The concentration of cytokines IL-17A in serum was assessed by standardized sandwich ELISA, while the expression of IL-17A mRNA in lung was examined by quantitative real-time RT-PCR. Briefly, our data indicated that celastrol reduced body mass in DIO-OVA-induced obesity and asthma. Both baseline Rn and MCh AHR were significantly lower in celastrol group. Moreover, celastrol treatment decreased the frequency of Th17 cell expansion and reduced the production of IL-17A in both lung and serum. To sum up, our findings indicated that Th17 and its cytokine measured in the spleen and lung were closely associated with AHR. In addition, celastrol has shown the ability to suppress AHR through Th17 inhibition in obese asthmatic mice. PMID- 29445342 TI - The A2B Adenosine Receptor Modulates the Epithelial- Mesenchymal Transition through the Balance of cAMP/PKA and MAPK/ERK Pathway Activation in Human Epithelial Lung Cells. AB - The epithelial-mesenchymal transition (EMT) is a complex process in which cell phenotype switches from the epithelial to mesenchymal one. The deregulations of this process have been related with the occurrence of different diseases such as lung cancer and fibrosis. In the last decade, several efforts have been devoted in understanding the mechanisms that trigger and sustain this transition process. Adenosine is a purinergic signaling molecule that has been involved in the onset and progression of chronic lung diseases and cancer through the A2B adenosine receptor subtype activation, too. However, the relationship between A2BAR and EMT has not been investigated, yet. Herein, the A2BAR characterization was carried out in human epithelial lung cells. Moreover, the effects of receptor activation on EMT were investigated in the absence and presence of transforming growth factor-beta (TGF-beta1), which has been known to promote the transition. The A2BAR activation alone decreased and increased the expression of epithelial markers (E-cadherin) and the mesenchymal one (Vimentin, N-cadherin), respectively, nevertheless a complete EMT was not observed. Surprisingly, the receptor activation counteracted the EMT induced by TGF-beta1. Several intracellular pathways regulate the EMT: high levels of cAMP and ERK1/2 phosphorylation has been demonstrated to counteract and promote the transition, respectively. The A2BAR stimulation was able to modulated these two pathways, cAMP/PKA and MAPK/ERK, shifting the fine balance toward activation or inhibition of EMT. In fact, using a selective PKA inhibitor, which blocks the cAMP pathway, the A2BAR-mediated EMT promotion were exacerbated, and conversely the selective inhibition of MAPK/ERK counteracted the receptor-induced transition. These results highlighted the A2BAR as one of the receptors involved in the modulation of EMT process. Nevertheless, its activation is not enough to trigger a complete transition, its ability to affect different intracellular pathways could represent a mechanism at the basis of EMT maintenance/inhibition based on the extracellular microenvironment. Despite further investigations are needed, herein for the first time the A2BAR has been related to the EMT process, and therefore to the different EMT-related pathologies. PMID- 29445345 TI - The Impact of Sex Differences on Odor Identification and Facial Affect Recognition in Patients with Schizophrenia Spectrum Disorders. AB - Background: Social interactive functions such as facial emotion recognition and smell identification have been shown to differ between women and men. However, little is known about how these differences are mirrored in patients with schizophrenia and how these abilities interact with each other and with other clinical variables in patients vs. healthy controls. Methods: Standardized instruments were used to assess facial emotion recognition [Facially Expressed Emotion Labelling (FEEL)] and smell identification [University of Pennsylvania Smell Identification Test (UPSIT)] in 51 patients with schizophrenia spectrum disorders and 79 healthy controls; furthermore, working memory functions and clinical variables were assessed. Results: In both the univariate and the multivariate results, illness showed a significant influence on UPSIT and FEEL. The inclusion of age and working memory in the MANOVA resulted in a differential effect with sex and working memory as remaining significant factors. Duration of illness was correlated with both emotion recognition and smell identification in men only, whereas immediate general psychopathology and negative symptoms were associated with emotion recognition only in women. Conclusion: Being affected by schizophrenia spectrum disorder impacts one's ability to correctly recognize facial affects and identify odors. Converging evidence suggests a link between the investigated basic and social cognitive abilities in patients with schizophrenia spectrum disorders with a strong contribution of working memory and differential effects of modulators in women vs. men. PMID- 29445343 TI - Medicinal Plants from Near East for Cancer Therapy. AB - Background: Cancer is one of the major problems affecting public health worldwide. As other cultures, the populations of the Near East rely on medicinal herbs and their preparations to fight cancer. Methods: We compiled data derived from historical ethnopharmacological information as well as in vitro and in vivo results and clinical findings extracted from different literature databases including (PubMed, Scopus, Web of Science, and Google Scholar) during the past two decades. Results: In this survey, we analyzed the huge amount of data available on anticancer ethnopharmacological sources used in the Near East. Medicinal herbs are the most dominant ethnopharmacological formula used among cancer's patients in the Near East. The data obtained highlight for the first time the most commonly used medicinal plants in the Near East area for cancer treatment illustrating their importance as natural anticancer agents. The literature survey reveals that various Arum species, various Artemisia species, Calotropis procera, Citrullus colocynthis, Nigella sativa, Pulicaria crispa, various Urtica species, Withania somnifera, and others belong to the most frequently used plants among cancer patients in the Near East countries. Molecular modes of action that have been investigated for plant extracts and isolated compounds from Near East include cell cycle arrest and apoptosis induction with participation of major player in these processes such as p53 and p21, Bcl-2, Bax, cytochrome c release, poly (ADP-ribose) polymerase cleavage, activation of caspases, etc. Conclusion: The ethnopharmacology of the Near East was influenced by Arabic and Islamic medicine and might be promising for developing new natural and safe anticancer agents. Further research is required to elucidate their cellular and molecular mechanisms and to estimate their clinical activity.

PMID- 29445346 TI - Psychological Shift in Partners of People with Multiple Sclerosis Who Undertake Lifestyle Modification: An Interpretive Phenomenological Study. AB - : Introduction: Being in an intimate relationship with a person with multiple sclerosis (MS) may have a substantial impact on the partner's quality of life. Existing research has largely focused on negative impacts of MS for both people with MS (PwMS) and their partners and has sampled the population of partners of PwMS who have primarily adopted standard medical management only. Modifiable lifestyle factors have become increasingly recognized in the management of MS symptoms and disease progression. For partners of PwMS who have undertaken lifestyle modification as an additional strategy to minimize disease progression, the impacts, both positive and negative remain unexplored. This research is unique as it focuses on partners of PwMS who have attempted to adopt major lifestyle interventions outside of the prevailing paradigm of MS management. Aim: To explore and interpret the lived experiences of partners of PwMS who have adopted lifestyle modification, to understand partners' attitudes to and experiences of the effect of MS and lifestyle modification on their life, relationship and view of the future. Method: Design: a qualitative, interpretive, phenomenological study using semi-structured interviews. PARTICIPANTS: English speaking; aged 18 years or more; in a spousal relationship for 12 months or more with a person with MS who had attended a residential lifestyle educational intervention and undertaken lifestyle modification. ANALYSIS: Interviews were recorded, transcribed verbatim and thematically analyzed using NVivoTM software. Results: Twenty-one partners were interviewed. This paper reports one of the study's themes, the psychological shift experienced by partners of PwMS. Sub themes included adaptation; loss and grief; difficult emotions; reframing, re evaluating and re-prioritizing; hope and optimism; empowerment and taking control; and self-awareness, greater understanding and personal growth. Conclusion: Partners of PwMS who have undertaken lifestyle modification experienced a broad range of psychological adjustments. Whilst reflecting the potential difficulties that partners of PwMS may experience, this group experienced a range of positive psychological changes that add to the literature regarding partners' potential experiences and may provide hope for those in partnerships with people with MS. This study provides themes to potentially inform a quantitative study of a larger population of partners of PwMS. PMID- 29445344 TI - Invertebrate Trehalose-6-Phosphate Synthase Gene: Genetic Architecture, Biochemistry, Physiological Function, and Potential Applications. AB - The non-reducing disaccharide trehalose is widely distributed among various organisms. It plays a crucial role as an instant source of energy, being the major blood sugar in insects. In addition, it helps countering abiotic stresses. Trehalose synthesis in insects and other invertebrates is thought to occur via the trehalose-6-phosphate synthase (TPS) and trehalose-6-phosphate phosphatase (TPP) pathways. In many insects, the TPP gene has not been identified, whereas multiple TPS genes that encode proteins harboring TPS/OtsA and TPP/OtsB conserved domains have been found and cloned in the same species. The function of the TPS gene in insects and other invertebrates has not been reviewed in depth, and the available information is quite fragmented. The present review discusses the current understanding of the trehalose synthesis pathway, TPS genetic architecture, biochemistry, physiological function, and potential sensitivity to insecticides. We note the variability in the number of TPS genes in different invertebrate species, consider whether trehalose synthesis may rely only on the TPS gene, and discuss the results of in vitro TPS overexpression experiment. Tissue expression profile and developmental characteristics of the TPS gene indicate that it is important in energy production, growth and development, metamorphosis, stress recovery, chitin synthesis, insect flight, and other biological processes. We highlight the molecular and biochemical properties of insect TPS that make it a suitable target of potential pest control inhibitors. The application of trehalose synthesis inhibitors is a promising direction in insect pest control because vertebrates do not synthesize trehalose; therefore, TPS inhibitors would be relatively safe for humans and higher animals, making them ideal insecticidal agents without off-target effects.

PMID- 29445348 TI - Taekwondo Fighting in Training Does Not Simulate the Affective and Cognitive Demands of Competition: Implications for Behavior and Transfer. AB - Enhancing practice design is critical to facilitate transfer of learning. Considerable research has focused on the role of perceptual information in practice simulation, yet has neglected how affect and cognition are shaped by practice environments and whether this influences the fidelity of behavior (Headrick et al., 2015). This study filled this gap by examining the fidelity of individual (cognition, affect, and actions) and interpersonal behavior of 10 highly skilled Australian Taekwondo athletes fighting in training compared to competition. Interpersonal behavior was assessed by tracking location coordinates to analyze distance-time coordination tendencies of the fighter-fighter system. Individual actions were assessed through notational analysis and approximate entropy calculations of coordinate data to quantify the (un)predictability of movement displacement. Affect and cognition were assessed with mixed-methods that included perceptual scales measuring anxiety, arousal, and mental effort, and post-fight video-facilitated confrontational interviews to explore how affect and cognitions might differ. Quantitative differences were assessed with mixed models and dependent t-tests. Results reveal that individual and interpersonal behavior differed between training and competition. In training, individuals attacked less (d = 0.81, p < 0.05), initiated attacks from further away (d = -0.20, p < 0.05) and displayed more predictable movement trajectories (d = 0.84, p < 0.05). In training, fighters had lower anxiety (d = -1.26, p < 0.05), arousal (d = -1.07, p < 0.05), and mental effort (d = -0.77, p < 0.05). These results were accompanied by changes in interpersonal behavior, with larger interpersonal distances generated by the fighter-fighter system in training (d = 0.80, p < 0.05). Qualitative data revealed the emergence of cognitions and affect specific to the training environment, such as reductions in pressure, arousal, and mental challenge. Findings highlight the specificity of performer-environment interactions. Fighting in training affords reduced affective and cognitive demands and a decrease in action fidelity compared to competition. In addition to sampling information, representative practice needs to consider modeling the cognitions and affect of competition to enhance transfer. PMID- 29445350 TI - Captive Bottlenose Dolphins Do Discriminate Human-Made Sounds Both Underwater and in the Air. AB - Bottlenose dolphins (Tursiops truncatus) spontaneously emit individual acoustic signals that identify them to group members. We tested whether these cetaceans could learn artificial individual sound cues played underwater and whether they would generalize this learning to airborne sounds. Dolphins are thought to perceive only underwater sounds and their training depends largely on visual signals. We investigated the behavioral responses of seven dolphins in a group to learned human-made individual sound cues, played underwater and in the air. Dolphins recognized their own sound cue after hearing it underwater as they immediately moved toward the source, whereas when it was airborne they gazed more at the source of their own sound cue but did not approach it. We hypothesize that they perhaps detected modifications of the sound induced by air or were confused by the novelty of the situation, but nevertheless recognized they were being "targeted." They did not respond when hearing another group member's cue in either situation. This study provides further evidence that dolphins respond to individual-specific sounds and that these marine mammals possess some capacity for processing airborne acoustic signals. PMID- 29445351 TI - Scalar and Ignorance Inferences Are Both Computed Immediately upon Encountering the Sentential Connective: The Online Processing of Sentences with Disjunction Using the Visual World Paradigm. AB - Accounts based on the pragmatic maxim of quantity make different predictions about the computation of scalar versus ignorance inferences. These different predictions are evaluated in two eye-tracking experiments using a visual world paradigm to assess the on-line computation of inferences. The test sentences contained disjunction phrases, which engender both kinds of inferences. The first experiment documented that both inferences are computed immediately upon encountering the disjunctive connective, at nearly identical temporal locations. The second experiment was designed to determine whether or not there exists an intermediate stage at which the truth of the corresponding conjunction phrase is ignored. No such stage was found.

To examine the potential of online delivery as a way of increasing overall usage of services, this study looked at students' attitudes toward and likelihood of using both online and/or face-to-face counseling. A survey was conducted with 409 students from six universities in Malaysia participating. Approximately 35% of participants reported that they would be likely to utilize online counseling services but would be unlikely to participate in face-to-face counseling. Based on these results, it is suggested that offering online counseling, in addition to face-to-face services, could be an effective way for many university counseling centers to increase the utilization of their services and thus better serve their communities. PMID- 29445353 TI - Validation of the Italian Tinnitus Questionnaire Short Form (TQ 12-I) as a Brief Test for the Assessment of Tinnitus-Related Distress: Results of a Cross Sectional Multicenter-Study. AB - Objectives: The use of reliable and valid psychometric tools to assess subjectively experienced distress due to tinnitus is broadly recommended. The purpose of the study was the validation of the Italian version of Tinnitus Questionnaire 12 item short form (TQ 12-I) as a brief test for the assessment of patient reported tinnitus-related distress. Design: Cross-sectional multicenter questionnaire study. Setting: Tinnitus Center, European Hospital (Rome), the Department of Otorhinolaryngology, "Guglielmo da Saliceto" Hospital (Piacenza), and the Department of Audiology and Phoniatry, "Mater Domini" University Hospital (Catanzaro). Participants: One hundred and forty-three outpatients with tinnitus treated at one of the participating medical centers. Main Outcome Measures: Tinnitus Questionnaire Short Form (TQ 12-I), compared to the Tinnitus Handicap Inventory (THI), Brief Symptom Inventory (BSI), and Short Form (SF-36) Health Survey. Results: Our factor analysis revealed a two-factor solution (health anxiety, cognitive distress), accounting for 53.5% of the variance. Good internal consistency for the total score (alpha = 0.86) and both factors (alpha = 0.79 0.87) was found. Moderate correlations with the THI (r = 0.65, p < 0.001) indicated good convergent validity. Tinnitus distress was further correlated to increased psychological distress (r = 0.31, p < 0.001) and reduced emotional well being (r = -0.34, p < 0.001). Conclusion: The study clearly showed that the TQ 12 I is a reliable and valid instrument to assess tinnitus-related distress which can be used in clinical practice as well as for research. PMID- 29445354 TI - Effects of Acupuncture on the Recovery Outcomes of Stroke Survivors with Shoulder Pain: A Systematic Review. AB - Background: Poststroke shoulder pain limits stroke survivors' physical functioning, impairs their ability to perform daily activities, and compromises their quality of life. The use of acupuncture to manage shoulder pain after a stroke is believed to free the blockage of energy flow and produce analgesic effects, but the evidence is unclear. We therefore conducted a systematic review to summarize the current evidence on the effects of acupuncture on the recovery outcomes of stroke survivors with shoulder pain. Methods: Fourteen English and Chinese databases were searched for data from January 2009 to August 2017. The review included adult participants with a clinical diagnosis of ischemic or hemorrhagic stroke who had developed shoulder pain and had undergone conventional acupuncture, electroacupuncture, fire needle acupuncture, or warm needle acupuncture. The participants in the comparison group received the usual stroke care only. Results: Twenty-nine randomized controlled trials were included. Most studies were assessed as having a substantial risk of bias. Moreover, due to the high heterogeneity of the acupuncture therapies examined, pooling the results in a meta-analysis was not appropriate. A narrative summary of the results is thus presented. The review showed that conventional acupuncture can be associated with benefits in reducing pain and edema and improving upper extremity function and physical function. The effects of conventional acupuncture on improving shoulder range of motion (ROM) are in doubt because this outcome was only examined in two trials. Electroacupuncture might be effective in reducing shoulder pain and improving upper extremity function, and conclusions on the effects of electroacupuncture on edema, shoulder ROM, and physical function cannot be drawn due to the limited number of eligible trials. The evidence to support the use of fire needle or warm needle acupuncture in stroke survivors with shoulder pain is also inconclusive due to the limited number of studies. Conclusion: Although most studies reviewed concluded that conventional and electroacupuncture could be effective for management of shoulder pain after stroke, the very high potential for bias should be considered. Further work in this area is needed that employs standardized acupuncture treatment modalities, endpoint assessments, and blinding of treatments. PMID- 29445355 TI - Plasma Levels of Myonectin But Not Myostatin or Fibroblast-Derived Growth Factor 21 Are Associated with Insulin Resistance in Adult Humans without Diabetes Mellitus. AB - Background: Myokines are a group of protein mediators produced by skeletal muscle under stress or physical exertion. Even though their discovery and effects in cell culture and animal models of disease have elicited great enthusiasm, very little is known about their role in human metabolism. We assessed whether plasma concentrations of three known myokines [myonectin, myostatin, and fibroblast derived growth factor 21 (FGF-21)] would be associated with direct and indirect indicators of insulin resistance (IR) in individuals who did not have a diagnosis of diabetes. Methods: We studied 81 adults of both sexes comprising a wide range of body adiposity and insulin sensitivity. All participants underwent a thorough clinical assessment and a 5-point oral glucose tolerance test with calculation of multiple IR and insulin sensitivity indices. Twenty-one of them additionally underwent a hyperinsulinemic-euglycemic clamp with determination of steady-state whole-body insulin-stimulated glucose disposal ("M"). We compared plasma myokine concentrations across quartiles of IR indices and clinical IR surrogates, and explored the correlation of each myokine with the M-value. Results: Plasma myonectin levels increased monotonically across quartiles of the incremental area under the insulin curve (higher values indicate more IR) (p-trend = 0.021) and decreased monotonically across quartiles of the insulin sensitivity index (ISI - higher values indicate less IR) (p-trend = 0.012). After multivariate adjustment for other relevant determinants of IR (body mass index, age, and sex), the negative association of myonectin with ISI persisted (standardized beta = -0.235, p = 0.023). Myostatin was not associated with any clinical IR indicator or direct IR index measure. In multivariate analyses, FGF-21 showed a trend toward a positive correlation with glucose disposal that did not reach statistical significance (standardized beta = 0.476, p = 0.091). Conclusion: The secretion of myonectin may constitute an attempt at a compensatory mechanism against IR in humans. PMID- 29445356 TI - DHEA Supplementation Confers No Additional Benefit to that of Growth Hormone on Pregnancy and Live Birth Rates in IVF Patients Categorized as Poor Prognosis. AB - Background: In vitro fertilization (IVF) patients receive various adjuvant therapies to enhance success rates, but the true benefit is actively debated. Growth hormone (GH) and dehydroepiandrosterone (DHEA) supplementation were assessed in women undergoing fresh IVF transfer cycles and categorized as poor prognosis from five criteria. Methods: Data were retrospectively analyzed from 626 women undergoing 626 IVF cycles, where they received no adjuvant, GH alone, or GH-DHEA in combination. A small group received DHEA alone. The utilization of adjuvants was decided between the attending clinician and the patient depending on various factors including cost. Results: Despite patients being significantly older with lower ovarian reserve, live birth rates were significantly greater with GH alone (18.6%) and with GH-DHEA (13.0%) in comparison to those with no adjuvant (p < 0.003). No significant difference was observed between the GH groups (p = 0.181). Overall, patient age, quality of the transferred embryo, and GH treatment were the only significant independent predictors of live birth chance. Following adjustment for patient age, antral follicle count, and quality of transferred embryo, GH alone and GH-DHEA led to a 7.1-fold and 5.6-fold increase in live birth chance, respectively (p < 0.000). Conclusion: These data indicated that GH adjuvant may support more live births, particularly in younger women, and importantly, the positive effects of GH treatment were still observed even if DHEA was also used in combination. However, supplementation with DHEA did not indicate any potentiating benefit or modify the effects of GH treatment. Due to the retrospective design, and the risk of a selection bias, caution is advised in the interpretation of the data. PMID- 29445357 TI - Gender Difference in the Association of Early- vs. Late-Onset Type 2 Diabetes with Non-Fatal Microvascular Disease in China: A Cross-sectional Study. AB - Background: This study aimed to test whether early-onset (defined as <40 years of age) type 2 diabetes mellitus (T2DM) imparted different risks of microvascular disease to Chinese men and women. Methods: 222,537 Chinese patients with T2DM were recruited in 630 hospitals from 106 cities in 30 provinces of China in 2012 using a cross-sectional design. Logistic regression analysis was performed to obtain odds ratios (ORs) of male vs. female for diabetic retinopathy (DR) and diabetic nephropathy (DN). Additive interaction was used to test whether male gender and early-onset T2DM had interactive effects for DR and DN. Results: More men than women with T2DM had DN (4.5 vs. 3.0%, P < 0.0001), DR (5.3 vs. 5.1%, P < 0.0001), and microvascular disease (either DN or DR) (8.4 vs. 7.1%, P < 0.0001). After adjustment for age and levels of hospitals, the effect sizes of early-onset T2DM for microvascular disease were higher in men than in women, with a 2.67 [95% confidence intervals (CI): 2.51-2.85] fold risk in men and a 2.53 (95% CI: 2.35 2.72) fold risk in women. The risk effect sizes were greatly attenuated by further adjusting for diabetes durations and other traditional risk factors, with a 1.28 (95% CI: 1.19-1.37) fold risk in men and a 1.07 (95% CI: 0.99-1.16) fold risk in women. After adjustment for diabetes durations and other traditional risk factors, using women with late-onset T2DM as the reference, co-presence of early onset and male gender significantly enhanced the ORs of either early-onset alone (1.10, 95% CI: 1.03-1.19) or male gender alone (0.96, 95% CI: 0.93-0.99) to 1.32 (95% CI: 1.24-1.41), with significant additive interaction. Kaplan-Meier analysis showed that in early-onset T2DM, DN developed 5 years earlier in men than in women. Conclusion: Early-onset T2DM increased more risk of microvascular complications in Chinese men than in women, most of increased risks being attributable to longer diabetes durations.

PMID- 29445359 TI - Composition and Activity of Microbial Communities along the Redox Gradient of an Alkaline, Hypersaline, Lake. AB - We compared the composition of microbial communities obtained by sequencing 16S rRNA gene amplicons with taxonomy derived from metatranscriptomes from the same samples. Samples were collected from alkaline, hypersaline Mono Lake, California, USA at five depths that captured the major redox zones of the lake during the onset of meromixis. The prokaryotic community was dominated by bacteria from the phyla Proteobacteria, Firmicutes, and Bacteroidetes, while the picoeukaryotic chlorophyte Picocystis dominated the eukaryotes. Most (80%) of the abundant (>1% relative abundance) OTUs recovered as amplicons of 16S rRNA genes have been reported in previous surveys, indicating that Mono Lake's microbial community has remained stable over 12 years that have included periods of regular, annual overturn interspersed by episodes of prolonged meromixis that result in extremely reducing conditions in bottom water. Metatranscriptomic sequences binned predominately to the Gammaproteobacteria genera Thioalkalivibrio (4-13%) and Thioalkalimicrobium (0-14%); and to the Firmicutes genera Dethiobacter (0-5%) and Clostridium (1-4%), which were also abundant in the 16S rRNA gene amplicon libraries. This study provides insight into the taxonomic affiliations of transcriptionally active communities of the lake's water column under different redox conditions. PMID- 29445361 TI - A Quasi-Steady-State Approximation to the Basic Target-Cell-Limited Viral Dynamics Model with a Non-Cytopathic Effect. AB - Analysis of previously published target-cell limited viral dynamic models for pathogens such as HIV, hepatitis, and influenza generally rely on standard techniques from dynamical systems theory or numerical simulation. We use a quasi steady-state approximation to derive an analytic solution for the model with a non-cytopathic effect, that is, when the death rates of uninfected and infected cells are equal. The analytic solution provides time evolution values of all three compartments of uninfected cells, infected cells, and virus. Results are compared with numerical simulation using clinical data for equine infectious anemia virus, a retrovirus closely related to HIV, and the utility of the analytic solution is discussed. PMID- 29445360 TI - The Dynamic Distribution of Small-Tail Han Sheep Microbiota across Different Intestinal Segments. AB - The sheep intestinal tract is characterized by a diverse microbial ecosystem that is vital for the host to digest diet material. The importance of gut microbiota (GM) of animals has also been widely acknowledged because of its pivotal roles in the health and well-being of animals. However, there are no relevant studies on GM of small-tail Han sheep, a superior mutton variety domestic in China. In this study, the structure and distribution of gut microflora were studied by high throughput sequencing technology. Results showed a significant difference between jejunum and cecum, jejunum, and rectum. Meanwhile, the cecum and rectum not only display higher species richness but also exhibit higher similarity of the bacterial diversity than that of the jejunum based on the results of abundance based coverage estimator (ACE), Chao1, and Shannon indexes. Firmicutes and Bacteroidetes were the predominant phyla in cecum and rectum, while higher relative abundances of Firmicutes and Cyanobacteria were observed in jejunum. At the genus level, Bacteroidetes, Ruminococcus, Lactobacillus, Flavonifractor, and Clostridium were the dominant genera in the cecum and rectum. An obvious dynamic distribution of Lactobacillus is continuously decreasing from the jejunum to the cecum, then to the rectum, whereas the result of Bacteroides is completely inverse. In addition, this study also found many kinds of bacteria associated with the production of volatile fatty acids (VFA) colonized in the large intestine. This study is the first to investigate the distribution of intestinal flora in small-tail Han sheep. The findings provide an important indication for diagnosis and treatment of intestinal diseases in small-tail Han sheep, as well as offer a direction for the development of intestinal microecological preparations. PMID- 29445362 TI - Microbial Flora Associated with the Halophyte-Salsola imbricate and Its Biotechnical Potential. AB - Halophytes are associated with the intertidal forest ecosystem of Saudi Arabia and seemingly have an immense potential for yielding useful and important natural products. In this study we have aimed to isolate and characterize the endophytic and rhizospheric bacterial communities from the halophyte, Salsola imbricata, In addition these bacterial strains were identified and selected strains were further studied for bioactive secondary metabolites. At least 168 rhizspheric and endophytic bacteria were isolated and of these 22 were active antagonists against the oomycetous fungal plant pathogens, Phytophthora capsici and Pythium ultimum. Active cultures were mainly identified with molecular techniques (16S r DNA) and this revealed 95.7-100% sequence similarities with relevant type strains. These microorgansims were grouped into four major classes: Actinobacteria, Firmicutes, beta-Proteobacteria, and gamma-Proteobacteria. Production of fungal cell wall lytic enzymes was detected mostly in members of Actinobacteria and Firmicutes. PCR screening for type I polyketide synthases (PKS-I), type II polyketide synthases (PKS-II) and nonribosomal peptide synthetases (NRPS) revealed 13 of the 22 strains (59%) were positive for at least one of these important biosynthetic genes that are known to be involved in the synthesis of important antibiotics. Four bacterial strains of Actinobacteria with potential antagonistic activity including two rhizobacteria, EA52 (Nocardiopsis sp.), EA58 (Pseudonocardia sp.) and two endophytic bacteria Streptomyces sp. (EA65) and Streptomyces sp. (EA67) were selected for secondary metabolite analyses using LC-MS. As a result, the presence of different bioactive compounds in the culture extracts was detected some of which are already reported for their diverse biological activities including antibiotics such as Sulfamethoxypyridazine, Sulfamerazine, and Dimetridazole. In conclusion, this study provides an insight into antagonistic bacterial population especially the Actinobacteria from S. imbricata, producing antifungal metabolites of medical significance and characterized taxonomically in future. PMID- 29445363 TI - Helicobacter pylori Infection Is Not Associated with Non-alcoholic Fatty Liver Disease: A Cross-Sectional Study in China. AB - Background and Aim:Helicobacter pylori infection has been reported to promote the development of a variety of extra-digestive manifestations, including type 2 diabetes, cardiovascular and liver diseases. Recently, the association between H. pylori infection and non-alcoholic fatty liver disease (NAFLD) was also proposed. However, evidence from different studies was controversial. We therefore performed this study to investigate the relationship between them in a large population of apparently healthy subjects in China. Methods: A total of 21,456 subjects underwent a healthy checkup program were included. H. pylori infection was detected by 14C urea breath test (14C-UBT) and NAFLD was diagnosed by ultrasonography. Results: Subjects infected with H. pylori had a more unfavorable metabolic profile, including higher levels of body mass index (BMI), blood pressure, triglycerides (TG) and lower levels of high-density lipoprotein cholesterol (HDL-C), as compared with those without H. pylori infection (all P < 0.05). Moreover, the prevalence rate of NAFLD was significantly increased in subjects with H. pylori infection when compared with those without H. pylori in women (23.6% vs. 21.5%, P < 0.05), but not in men (46.5% vs. 45.5%, P > 0.05). After adjusting for confounding factors including age, sex, BMI, blood pressure and lipid profiles, multivariate logistic analysis revealed that H. pylori infection was not independently associated with the risk of NAFLD in the total population (OR = 0.9, 95% CI = 0.9-1.0, P = 0.097). Also, subgroup analysis (stratified by age, sex, BMI, and diabetes status) showed no independent association between H. pylori infection and NAFLD. Conclusion: Our data suggests that H. pylori infection is not independently associated with the risk of NAFLD in apparently healthy subjects. PMID- 29445364 TI - Non-specific Effect of Vaccines: Immediate Protection against Respiratory Syncytial Virus Infection by a Live Attenuated Influenza Vaccine. AB - The non-specific effects (NSEs) of vaccines have been discussed for their potential long-term beneficial effects beyond direct protection against a specific pathogen. Cold-adapted, live attenuated influenza vaccine (CAIV) induces local innate immune responses that provide a broad range of antiviral immunity. Herein, we examined whether X-31ca, a donor virus for CAIVs, provides non specific cross-protection against respiratory syncytial virus (RSV). The degree of RSV replication was significantly reduced when X-31ca was administered before RSV infection without any RSV-specific antibody responses. The vaccination induced an immediate release of cytokines and infiltration of leukocytes into the respiratory tract, moderating the immune perturbation caused by RSV infection. The potency of protection against RSV challenge was significantly reduced in TLR3 /- TLR7-/- mice, confirming that the TLR3/7 signaling pathways are necessary for the observed immediate and short-term protection. The results suggest that CAIVs provide short-term, non-specific protection against genetically unrelated respiratory pathogens. The additional benefits of CAIVs in mitigating acute respiratory infections for which vaccines are not yet available need to be assessed in future studies. PMID- 29445365 TI - Babesia microti Infection Changes Host Spleen Architecture and Is Cleared by a Th1 Immune Response. AB - Babesia microti is a malaria-like parasite, which infects ~2000 people annually, such that babesiosis is now a notifiable disease in the United States. Immunocompetent individuals often remain asymptomatic and are tested only after they feel ill. Susceptible C3H/HeJ mice show several human-like disease manifestations and are ideal to study pathogenesis of Babesia species. In this study, we examined parasitemia of B. microti at different time points and assessed its impact on hemoglobin levels in blood, on spleen pathology and overall immune response in C3H/HeJ mice. Peak parasitemia of 42.5% was immediately followed by diminished hemoglobin level. Parasitemia at 21 days of infection was barely detectable by microscopy presented 5.7 * 108 to 5.9 * 109B. microti DNA copies confirming the sensitivity of our qPCR. We hypothesize that qPCR detects DNA released from recently lysed parasites or from extracellular B. microti in blood, which are not easily detected in blood smears and might result in under-diagnosis of babesiosis in patients. Splenectomized patients have been reported to show increased babesiosis severity and result in high morbidity and mortality. These results emphasize the importance of splenic immunity in resolution of B. microti infection. Splenomegaly in infected mice associated with destruction of marginal zone with lysed erythrocytes and released B. microti life forms in our experiments support this premise. At conclusion of the experiment at 21 days post-infection, significant splenic B and T cells depletion and increase in macrophages levels were observed in B. microti infected mice suggesting a role of macrophage in disease resolution. Infected mice also showed significantly higher plasmatic concentration of CD4 Th1 cells secreted cytokines such as IL-2 and IFN-gamma while cytokines such as IL-4, IL-5, and IL-13 secreted by Th2 cells increase was not always significant. Thus, Th1 cells-mediated immunity appears to be important in clearance of this intracellular pathogen. Significant increase in IL-6 that promotes differentiation of Th17 cells was observed but it resulted in only moderate change in IL-17A, IL-17F, IL-21, and IL-22, all secreted by Th17 cells. A similar immune response to Trypanosoma infection has been reported to influence the clearance of this protozoan, and co-infecting pathogen(s). PMID- 29445366 TI - The Effect of DNA Extraction Methods on Observed Microbial Communities from Fibrous and Liquid Rumen Fractions of Dairy Cows. AB - DNA based methods have been widely used to study the complexity of the rumen microbiota, and it is well known that the method of DNA extraction is a critical step in enabling accurate assessment of this complexity. Rumen fluid (RF) and fibrous content (FC) fractions differ substantially in terms of their physical nature and associated microorganisms. The aim of this study was therefore to assess the effect of four DNA extraction methods (RBB, PBB, FDSS, PQIAmini) differing in cell lysis and/or DNA recovery methods on the observed microbial diversity in RF and FC fractions using samples from four rumen cannulated dairy cows fed 100% grass silage (GS100), 67% GS and 33% maize silage (GS67MS33), 33% GS and 67% MS (GS33MS67), or 100% MS (MS100). An ANOVA statistical test was applied on DNA quality and yield measurements, and it was found that the DNA yield was significantly affected by extraction method (p < 0.001) and fraction (p < 0.001). The 260/280 ratio was not affected by extraction (p = 0.08) but was affected by fraction (p = 0.03). On the other hand, the 260/230 ratio was affected by extraction method (p < 0.001) but not affected by fraction (p = 0.8). However, all four extraction procedures yielded DNA suitable for further analysis of bacterial, archaeal and anaerobic fungal communities using quantitative PCR and pyrosequencing of relevant taxonomic markers. Redundancy analysis (RDA) of bacterial 16S rRNA gene sequence data at the family level showed that there was a significant effect of rumen fraction (p = 0.012), and that PBB (p = 0.012) and FDSS (p = 0.024) also significantly contributed to explaining the observed variation in bacterial community composition. Whilst the DNA extraction method affected the apparent bacterial community composition, no single extraction method could be concluded to be ineffective. No obvious effect of DNA extraction method on the anaerobic fungi or archaea was observed, although fraction effects were evident for both. In summary, the comprehensive assessment of observed communities of bacteria, archaea and anaerobic fungi described here provides insight into a rational basis for selecting an optimal methodology to obtain a representative picture of the rumen microbiota. PMID- 29445367 TI - Microbial Communities and Diversities in Mudflat Sediments Analyzed Using a Modified Metatranscriptomic Method. AB - Intertidal mudflats are land-sea interaction areas and play important roles in global nutrient cycles. However, a comprehensive understanding of microbial communities in these mudflats remains elusive. In this study, mudflat sediment samples from the Dongtan wetland of Chongming Island, the largest alluvial island in the world, were collected. Using a modified metatranscriptomic method, the depth-wise distributions of potentially active microbial communities were investigated based on small subunit ribosomal RNA (SSU rRNA) sequences. Multiple environmental factors were also measured and analyzed in conjunction with the prokaryotic composition profiles. A prokaryotic diversity analysis based on the metatranscriptome datasets revealed two or threefold higher diversity indices (associated with potentially active microbes participating in biogeochemical processes in Dongtan) compared with the diversity indices based on 16S rRNA gene amplicons. Bacteria were numerically dominant relative to archaea, and the potentially active prokaryotic taxa were mostly assigned to the bacterial phyla Chloroflexi, Acidobacteria, and Bacteroidetes and the classes Delta- and Gamma proteobacteria, along with the archaeal lineages phylum Bathyarchaeota and the order Thermoplasmatales. The total nitrogen and carbon content of the sediment samples were environmental factors that significantly affected the depth-wise distributions of both bacterial and archaeal communities. Furthermore, the activity of potentially active taxa (including the prevalent order Desulfobacterales and family Anaerolineaceae) appeared to be significantly underestimated by PCR-based methods, notably at the DNA level, and indicates that using normal PCR amplification of DNA limits the study of potential microbial activity. This is the first study of potentially active microbial communities in depth-wise sediments from Dongtan. The improved knowledge of microbial communities in Dongtan provides a foundation for exploring biogeochemical cycling and microbial functions. PMID- 29445368 TI - Beneficial Oral Biofilms as Smart Bioactive Interfaces. AB - Periodontitis is a very common health problem caused by formation of pathogenic bacterial biofilm that triggers inflammation resulting in either reversible gingivitis or irreversible periodontal hard and soft tissue damages, leading to loss of teeth when left untreated. Commensal bacteria play an important role in oral health in many aspects. Mainly by colonizing oral tissues, they (i) contribute to maturation of immune response, and (ii) foreclose attachment of pathobiont and, therefore, prevent from infection. The main goal of the study was to investigate if blocking of receptors on a commensal biofilm can prevent or reduce the attachment of pathogenic strains. To do so, biofilm produced by commensal Streptococcus sanguinis was treated with whole cell lysate of pathobionts Fusobacterium nucleatum or Porphyromonas gingivalis, followed by incubation with respective strain(s). The study revealed significant reduction in pathobiont adhesion to lysate-treated commensal biofilm. Therefore, adhesion of pathobionts onto the lysate-blocked biofilm was hindered; however, not completely eliminated supporting the idea that such approach in the oral cavity would benefit the production of a well-balanced and healthy bioactive interface. PMID- 29445369 TI - Turgor Pressure and Possible Constriction Mechanisms in Bacterial Division. AB - Bacterial cytokinesis begins with the assembly of FtsZ into a Z ring at the center of the cell. The Z-ring constriction in Gram-negative bacteria may occur in an environment where the periplasm and the cytoplasm are isoosmotic, but in Gram-positive bacteria the constriction may have to overcome a substantial turgor pressure. We address three potential sources of invagination force. (1) FtsZ itself may generate force by curved protofilaments bending the attached membrane. This is sufficient to constrict liposomes in vitro. However, this force is on the order of a few pN, and would not be enough to overcome turgor. (2) Cell wall (CW) synthesis may generate force by pushing the plasma membrane from the outside. However, this would probably require some kind of Brownian ratchet to separate the CW and membrane sufficiently to allow a glycan strand to slip in. The elastic element is not obvious. (3) Excess membrane production has the potential to contribute significantly to the invagination force. If the excess membrane is produced under the CW, it would force the membrane to bleb inward. We propose here that a combination of FtsZ pulling from the inside, and excess membrane pushing membrane inward may generate a substantial constriction force at the division site. This combined force generation mechanism may be sufficient to overcome turgor pressure. This would abolish the need for a Brownian ratchet for CW growth, and would permit CW to operate by reinforcing the constrictions generated by FtsZ and excess membrane. PMID- 29445370 TI - Ex Vivo Expanded Human Non-Cytotoxic CD8+CD45RClow/- Tregs Efficiently Delay Skin Graft Rejection and GVHD in Humanized Mice. AB - Both CD4+ and CD8+ Tregs play a critical role in the control of immune responses and immune tolerance; however, our understanding of CD8+ Tregs is limited while they are particularly promising for therapeutic application. We report here existence of highly suppressive human CD8+CD45RClow/- Tregs expressing Foxp3 and producing IFNgamma, IL-10, IL-34, and TGFbeta to mediate their suppressive activity. We demonstrate that total CD8+CD45RClow/- Tregs can be efficiently expanded in the presence of anti-CD3/28 mAbs, high-dose IL-2 and IL-15 and that such expanded Tregs efficiently delay GVHD and human skin transplantation rejection in immune humanized mice. Robustly expanded CD8+ Tregs displayed a specific gene signature, upregulated cytokines and expansion in the presence of rapamycin greatly improved proliferation and suppression. We show that CD8+CD45RClow/- Tregs are equivalent to canonical CD4+CD25highCD127low/- Tregs for suppression of allogeneic immune responses in vitro. Altogether, our results open new perspectives to tolerogenic strategies in human solid organ transplantation and GVHD. PMID- 29445371 TI - Effects of MicroRNA on Regulatory T Cells and Implications for Adoptive Cellular Therapy to Ameliorate Graft-versus-Host Disease. AB - Regulatory T cells (Tregs) are key mediators of the immune system. MicroRNAs (miRNAs) are a family of ~22 nucleotide non-coding RNAs that are processed from longer precursors by the RNases Drosha and Dicer. miRNA regulates protein expression posttranscriptionally through mRNA destabilization or translational silencing. A critical role for miRNA in Treg function was initially discovered when both Dicer and Drosha knockout (KO) mice were found to develop a fatal autoimmune disease phenotypically similar to Foxp3 KO mice. PMID- 29445372 TI - Robust Phenotypic Activation of Eosinophils during Experimental Toxocara canis Infection. AB - Eosinophils are multifunctional cells that have cytotoxic proinflammatory activities and stimulate CD4+ T-cells in experimental models of allergy and parasitic infections. Eosinophils, when exposed to antigens, are activated, expressing the CD38/CD69 molecules and exhibited increased expression of major histocompatibility complex (MHC-II), CD80 and CD86, suggesting they play a role upon Toxocara canis antigen stimulation. In the present study, we evaluated the profile of eosinophils using conventional and image flow cytometry upon experimental T. canis infection. T. canis antigens induced a robust activation on this subset, contributing to the immune responses elicited in the experimental model for T. canis-associated visceral larva migrans syndrome. Data analysis demonstrated that, during murine T. canis infection, eosinophils from peripheral blood, spleen, and bone marrow presented upregulated expression of CD69/MHC II/CD80/CD86. As opposed to splenic and bone marrow eosinophils, circulating eosinophils had increased expression of activation markers upon T. canis infection. The enhanced connectivity between eosinophils and T-cells in T. canis infected mice in all three compartments (peripheral blood, spleen, and bone marrow) also supports the hypothesis that eosinophils may adopt a role during T. canis infection. Moreover, in vitro T. canis antigen stimulation resulted in activation and upregulation of co-stimulatory-related molecules by bone marrow derived eosinophils. Our findings are evidence of activation and upregulation of important activation and co-stimulatory-related molecules in eosinophils and suggest a reshape of activation hierarchy toward eosinophils during experimental T. canis infection. PMID- 29445373 TI - Tissue-Dependent Tumor Microenvironments and Their Impact on Immunotherapy Responses. AB - Recent advances in cancer immunology have led to a better understanding of the role of the tumor microenvironment (TME) in tumor initiation, progression, and metastasis. Tumors can occur at many locations within the body and coevolution between malignant tumor cells and non-malignant cells sculpts the TME at these sites. It has become increasingly clear that there are specific differences of the TMEs at different anatomical locations, and these tissue-specific TMEs regulate tumor growth, determine metastatic progression, and impact on the outcome of therapy responses. Herein, we review the scientific advances in understanding tissue-specific TMEs, discuss their impact on immunotherapeutic response, and assess the current clinical knowledge in this emerging field. A deeper understanding of the tissue-specific TME will help to develop effective immunotherapies against tumors and their metastases and assist in predicting clinical outcomes. PMID- 29445374 TI - The Immunome in Two Inherited Forms of Pulmonary Fibrosis. AB - : The immunome (immune cell phenotype, gene expression, and serum cytokines profiling) in pulmonary fibrosis is incompletely defined. Studies focusing on inherited forms of pulmonary fibrosis provide insights into mechanisms of fibrotic lung disease in general. To define the cellular and molecular immunologic phenotype in peripheral blood, high-dimensional flow cytometry and large-scale gene expression of peripheral blood mononuclear cells and serum proteomic multiplex analyses were performed and compared in a cohort with familial pulmonary fibrosis (FPF), an autosomal dominant disorder with incomplete penetrance; Hermansky-Pudlak syndrome pulmonary fibrosis (HPSPF), a rare autosomal recessive disorder; and their unaffected relatives. Our results showed high peripheral blood concentrations of activated central memory helper cells in patients with FPF. Proportions of CD38+ memory CD27- B-cells, IgA+ memory CD27+ B cells, IgM+ and IgD+ B-cells, and CD39+ T helper cells were increased whereas those of CD39- T helper cells were reduced in patients affected with either familial or HPSPF. Gene expression and serum proteomic analyses revealed enrichment of upregulated genes associated with mitosis and cell cycle control in circulating mononuclear cells as well as altered levels of several analytes, including leptin, cytokines, and growth factors. In conclusion, dysregulation of the extra-pulmonary immunome is a phenotypic feature of FPF or HPSPF. Further studies investigating the blood immunome are indicated to determine the role of immune system dysregulation in the pathogenesis of pulmonary fibrosis.

AB - Cytochromes are expressed in many different tissues of the human body. They are found mostly in intestinal and hepatic tissues. Cytochromes P450 (CYPs) are enzymes that oxidize substances using iron and are able to metabolize a large variety of xenobiotic substances. CYP enzymes are linked to a wide array of reactions including and O-dealkylation, S-oxidation, epoxidation, and hydroxylation. The activity of the typical P450 cytochrome is influenced by a variety of factors, such as genus, environment, disease state, herbicide, alcohol, and herbal medications. However, diet seems to play a major role. The mechanisms of action of dietary chemicals, macro- and micronutrients on specific CYP isoenzymes have been extensively studied. Dietary modulation has effects upon the metabolism of xenobiotics. Cytochromes harbor intra- or interindividual and intra- or interethnic genetic polymorphisms. Bacteria were shown to express CYP like genes. The tremendous metabolic activity of the microbiota is associated to its abundant pool of CYP enzymes, which catalyze phase I and II reactions in drug metabolism. Disease states, intestinal disturbances, aging, environmental toxic effects, chemical exposures or nutrition modulate the microbial metabolism of a drug before absorption. A plethora of effects exhibited by most of CYP enzymes can resemble those of proinflammatory cytokines and IFNs. Moreover, they are involved in the initiation and persistence of pathologic pain by directly activating sensory neurons and inflammatory cytokines.

AB - Life-history theory is fundamental to understanding how animals allocate resources among survival, development, and reproduction, and among traits within these categories. Immediate trade-offs occur within a short span of time and, therefore, are more easily detected. Trade-offs, however, can also manifest across stages of the life cycle, a phenomenon known as carryover effects. We investigated trade-offs on both time scales in two populations of Dall sheep (Ovis dalli dalli) in Southcentral Alaska. Specifically, we (i) tested for glucocorticoid-mediated carryover effects from the breeding season on reproductive success and immune defenses during parturition and (ii) tested for trade-offs between immune defenses and reproduction within a season. We observed no relationship between cortisol during mating and pregnancy success; however, we found marginal support for a negative relationship between maternal cortisol and neonate birth weights. Low birth weights, resulting from high maternal cortisol, may result in low survival or low fecundity for the neonate later in life, which could result in overall population decline. We observed a negative relationship between pregnancy and bacterial killing ability, although we observed no relationship between pregnancy and haptoglobin. Study site affected bactericidal capacity and the inflammatory response, indicating the influence of external factors on immune responses, although we could not test hypotheses about the cause of those differences. This study helps advance our understanding of the plasticity and complexity of the immune system and provides insights into the how individual differences in physiology may mediate differences in fitness. PMID- 29445377 TI - Mouse Models of Influenza Infection with Circulating Strains to Test Seasonal Vaccine Efficacy. AB - Influenza virus infection is a significant cause of morbidity and mortality worldwide. The surface antigens of influenza virus change over time blunting both naturally acquired and vaccine induced adaptive immune protection. Viral antigenic drift is a major contributing factor to both the spread and disease burden of influenza. The aim of this study was to develop better infection models using clinically relevant, influenza strains to test vaccine induced protection. CB6F1 mice were infected with a range of influenza viruses and disease, inflammation, cell influx, and viral load were characterized after infection. Infection with circulating H1N1 and representative influenza B viruses induced a dose-dependent disease response; however, a recent seasonal H3N2 virus did not cause any disease in mice, even at high titers. Viral infection led to recoverable virus, detectable both by plaque assay and RNA quantification after infection, and increased upper airway inflammation on day 7 after infection comprised largely of CD8 T cells. Having established seasonal infection models, mice were immunized with seasonal inactivated vaccine and responses were compared to matched and mismatched challenge strains. While the H1N1 subtype strain recommended for vaccine use has remained constant in the seven seasons between 2010 and 2016, the circulating strain of H1N1 influenza (2009 pandemic subtype) has drifted both genetically and antigenically since 2009. To investigate the effect of this observed drift on vaccine induced protection, mice were immunized with antigens from A/California/7/2009 (H1N1) and challenged with H1N1 subtype viruses recovered from 2009, 2010, or 2015. Vaccination with A/California/7/2009 antigens protected against infection with either the 2009 or 2010 strains, but was less effective against the 2015 strain. This observed reduction in protection suggests that mouse models of influenza virus vaccination and infection can be used as an additional tool to predict vaccine efficacy against drift strains. PMID- 29445378 TI - Fc-Glycosylation in Human IgG1 and IgG3 Is Similar for Both Total and Anti-Red Blood Cell Anti-K Antibodies. AB - After albumin, immunoglobulin G (IgG) are the most abundant proteins in human serum, with IgG1 and IgG3 being the most abundant subclasses directed against protein antigens. The quality of the IgG-Fc-glycosylation has important functional consequences, which have been found to be skewed toward low fucosylation in some antigen-specific immune responses. This increases the affinity to IgG1-Fc-receptor (FcgammaR)IIIa/b and thereby directly affects downstream effector functions and disease severity. To date, antigen-specific IgG glycosylation have not been analyzed for IgG3. Here, we analyzed 30 pregnant women with anti-K alloantibodies from a prospective screening cohort and compared the type of Fc-tail glycosylation of total serum- and antigen-specific IgG1 and IgG3 using mass spectrometry. Total serum IgG1 and IgG3 Fc-glycoprofiles were highly similar. Fc glycosylation of antigen-specific IgG varied greatly between individuals, but correlated significantly with each other for IgG1 and IgG3, except for bisection. However, although the magnitude of changes in fucosylation and galactosylation were similar for both subclasses, this was not the case for sialylation levels, which were significantly higher for both total and anti-K IgG3. We found that the combination of relative IgG1 and IgG3 Fc-glycosylation levels did not improve the prediction of anti-K mediated disease over IgG1 alone. In conclusion, Fc-glycosylation profiles of serum- and antigen-specific IgG1 and IgG3 are highly similar. PMID- 29445379 TI - Contribution of Regulatory T Cells in Nucleotide-Binding Oligomerization Domain 2 Response to Influenza Virus Infection. AB - Influenza A virus (IAV) is recognized to cause severe pulmonary illnesses in humans, particularly in elderly and children. One of the features associated with IAV infection is an excessive lung inflammation due to an uncontrolled immune response. The nucleotide-binding oligomerization domain 2 (NOD2) receptor is known to recognize ssRNA viruses such as IAV, but its role in the inflammatory process during viral infections remains to be clarified. In a previous report, we have shown that activation of NOD2 with muramyl dipeptide (MDP) significantly reduces both viral loads and lung inflammation and also improves pulmonary function during IAV infection. These findings prompted us to further investigate whether NOD2 receptor may contribute to regulate inflammation during viral infection. In the present study, we show that administration of MDP to mice infected with IAV stimulates the migration of regulatory T (Treg) cells to the lungs. Such a presence of Treg cells was also accompanied with a reduction of neutrophils in the lungs during IAV infection, which correlated, with a significant decrease of Th17 cells. In our model, Treg cell recruitment is dependent of CXCL12 and CCL5 chemokines. Moreover, we show that the presence of Ly6Clow patrolling monocytes is required for Treg cells mobilization to the lung of mice treated with MDP. In fact, following monocyte depletion by administration of clodronate liposome, mobilization of Treg cells to the lungs of treated mice was found to occur when circulating Ly6Clow monocytes begin to reemerge. In addition, we also detected an increased production of TGF-beta, a cytokine contributing to Treg activity when blood Ly6Clow monocytes are restored. Together, our results demonstrate that MDP treatment can promote an anti inflammatory environment through the mobilization of Treg cells to the lung, a mechanism that requires the presence of Ly6Clow monocytes during IAV infection. Overall, our results suggest that activation of NOD2 receptor could be an appealing approach to control pulmonary inflammation in patients infected with IAV. PMID- 29445380 TI - The Role of Indoleamine-2,3-Dioxygenase in Cancer Development, Diagnostics, and Therapy. AB - Tumors are composed of abnormally transformed cell types and tissues that differ from normal tissues in their genetic and epigenetic makeup, metabolism, and immunology. Molecular compounds that modulate the immune response against neoplasms offer promising new strategies to combat cancer. Inhibitors targeting the indoleamine-2,3-dioxygenase 1 enzyme (IDO1) represent one of the most potent therapeutic opportunities to inhibit tumor growth. Herein, we assess the biochemical role of IDO1 in tumor metabolism and immune surveillance, and review current diagnostic and therapeutic approaches that are intended to increase the effectiveness of immunotherapies against highly aggressive and difficult-to-treat IDO-expressing cancers. PMID- 29445382 TI - Innovative Approaches to Evaluate Sugar Beet Responses to Changes in Sulfate Availability. AB - In this study, a system based on omics profiling was set-up for sugar beet (Beta vulgaris L. subsp. vulgaris) evaluation after changes in sulfate availability. Seedlings were grown on sulfate-deprived Hoagland solution. Six days after germination, 100 MUM MgSO4 was added to the solution. Root samples were collected 36 h after treatments. WinRHIZO root-scanning approach was used for the automated image analysis of plant root morphology. Inductively Coupled Plasma Spectrometry (ICP-OES) and quadrupole-time-of-flight mass spectrometry (Q-TOF) were used for ionomic and metabolic analysis, respectively. Nanofluidic real-time PCR (OpenArray system) was used for molecular profiling. OpenArray chips were designed with TaqMan probes for 53 sugar beet genes putatively involved in sulfate nutrition. At morphological level treated seedlings showed significantly higher values (P < 0.01) than untreated plants for root traits related to soil exploration and nutrient uptake, such as total root length, fine roots length and root tips number. ICP-OES, Q-TOF and transcriptomic data revealed changes due to sulfate availability in sugar beet samples. Two key results are highlighted in sulfate-supplied roots and leaves. Firstly, high expression levels of auxin efflux carrier component 1 (PIN) and 5-phosphoribosyl-anthranilate, precursor of tryptophan and auxin synthesis, were observed in roots. Secondly, high levels of 2-Cys peroxiredoxin BAS1, chloroplastic, thioredoxin reductase (NADPH) and cysteine synthase, chloroplastic/chromoplastic, O-acetylserine sulfhydrylase, involved in protection against oxidative stress and cysteine synthase activity, respectively, were observed in leaves. Based on our findings, the combination of evaluated omics approaches could become a key system for the evaluation of the nutritional status of sugar beet under different nutrient availability conditions. PMID- 29445381 TI - Proteins of TNF-alpha and IL6 Pathways Are Elevated in Serum of Type-1 Diabetes Patients with Microalbuminuria. AB - Soluble cytokine receptors may play an important role in development of microalbuminuria (MA) in type-1 diabetes (T1D). In this study, we measured 12 soluble receptors and ligands from TNF-alpha/IL6/IL2 pathways in T1D patients with MA (n = 89) and T1D patients without MA (n = 483) participating in the PAGODA study. Twelve proteins in the sera from T1D patients with and without MA were measured using multiplex Luminex assays. Ten serum proteins (sTNFR1, sTNFR2, sIL2Ralpha, MMP2, sgp130, sVCAM1, sIL6R, SAA, CRP, and sICAM1) were significantly elevated in T1D patients with MA. After adjusting for age, duration of diabetes, and sex in logistic regression, association remained significant for seven proteins. MA is associated with increasing concentrations of all 10 proteins, with the strongest associations observed for sTNFR1 (OR = 108.3, P < 10-32) and sTNFR2 (OR = 65.5, P < 10-37), followed by sIL2Ralpha (OR = 12.9, P < 10-13), MMP2 (OR = 5.5, P < 10-6), sgp130 (OR = 5.2, P < 10-3), sIL6R (OR = 4.6, P < 10 4), and sVCAM1 (OR = 3.3, P < 10-4). We developed a risk score system based on the combined odds ratios associated with each quintile for each protein. The risk scores cluster MA patients into three subsets, each associated with distinct risk for MA attributable to proteins in the TNF-alpha/IL6 pathway (mean OR = 1, 13.5, and 126.3 for the three subsets, respectively). Our results suggest that the TNF alpha/IL6 pathway is overactive in approximately 40% of the MA patients and moderately elevated in the middle 40% of the MA patients. Our results suggest the existence of distinct subsets of MA patients identifiable by their serum protein profiles. PMID- 29445383 TI - Study on Reproductive Biology of Rhododendron longipedicellatum: A Newly Discovered and Special Threatened Plant Surviving in Limestone Habitat in Southeast Yunnan, China. AB - Rhododendron longipedicellatum is a narrow endemic species and a subject of urgent demand in the domestic market and overseas. Its fascinating shapes, brilliantly gilvous flowers, and unusual flowering time endow this species with extremely high ornamental value. However, only five wild populations of R. longipedicellatum surviving in limestone habitat have been found through elaborate field investigation, and the number of the populations decreases further or is even confronted with risk of extinction due to the damage of human activities. To enhance the protection and utilization of R. longipedicellatum, this study systematically investigated several important aspects of reproductive biology, including floral syndrome, pollen viability and stigma receptivity, petal color reflectance, breeding system, and pollination biology. The results demonstrated that arched styles not only create obvious herkogamy that avoide self-pollination, but also effectively reduce rain damage to the intrinsic characteristics of the stigma surface secretions, promoting the female fitness of R. longipedicellatum in poor weather. Pollen viability maintained a high level over the flowering period. The reflectance spectrum of petals had two peaks at wavelengths of 360 and 580 nm. Tests of OCI, P/O and artificial pollination all indicated that R. longipedicellatum was self-compatible and that the breeding system was mixed mating. Geitonogamy mediated by Bombus braccatus was the primary pollination route in the natural environment, which suggested that the breeding system of R. longipedicellatum might be evolving from selfing to outcrossing. The pollination vector of R. longipedicellatum was very specific, in that only B. braccatus was confirmed to deliver pollen to the stigmas. Visitation frequency was influenced by the activity rhythms and resource requirements of the different castes (i.e., sex). B. braccatus workers were the most effective pollinators because of higher visitation frequency and more effective contribution to fruit production, whereas the presence of B. braccatus males might enhance pollen flow within the population to a certain extent. Finally, these findings not only provided a reliable theoretical basis for hybridization breeding of R. longipedicellatum as parents, but also laid a solid foundation for further molecular biology studies to more broadly reveal the mechanisms of its endangerment in the future.

PMID- 29445385 TI - Fagopyrum esculentum Alters Its Root Exudation after Amaranthus retroflexus Recognition and Suppresses Weed Growth. AB - Weed control by crops through growth suppressive root exudates is a promising alternative to herbicides. Buckwheat (Fagopyrum esculentum) is known for its weed suppression and redroot pigweed (Amaranthus retroflexus) control is probably partly due to allelopathic root exudates. This work studies whether other weeds are also suppressed by buckwheat and if the presence of weeds is necessary to induce growth repression. Buckwheat and different weeds were co-cultivated in soil, separating roots by a mesh allowing to study effects due to diffusion. Buckwheat suppressed growth of pigweed, goosefoot and barnyard grass by 53, 42, and 77% respectively without physical root interactions, probably through allelopathic compounds. Root exudates were obtained from sand cultures of buckwheat (BK), pigweed (P), and a buckwheat/pigweed mixed culture (BK-P). BK-P root exudates inhibited pigweed root growth by 49%. Characterization of root exudates by UHPLC-HRMS and principal component analysis revealed that BK and BK-P had a different metabolic profile suggesting that buckwheat changes its root exudation in the presence of pigweed indicating heterospecific recognition. Among the 15 different markers, which were more abundant in BK-P, tryptophan was identified and four others were tentatively identified. Our findings might contribute to the selection of crops with weed suppressive effects. PMID- 29445386 TI - Editorial: Evolution of Reproductive Organs in Land Plants. PMID- 29445387 TI - QTL Mapping in Three Connected Populations Reveals a Set of Consensus Genomic Regions for Low Temperature Germination Ability in Zea mays L. AB - Improving seed vigor in response to cold stress is an important breeding objective in maize that allows early sowing. Using two cold tolerant inbred lines 220 and P9-10 and two susceptible lines Y1518 and PH4CV, three connected F2:3 populations were generated for detecting quantitative trait locus (QTL) related to seed low-temperature germination ability. At 10 degrees C, two germination traits (emergence rate and germination index) were collected from a sand bed and three seedling traits (seedling root length, shoot length, and total length) were extracted from paper rolls. Significant correlations were found among all traits in all populations. Via single-population analysis, 43 QTL were detected with explained phenotypic variance of 0.62%~39.44%. Seventeen QTL explained more than 10% phenotypic variance; of them sixteen (94.12%) inherited favorable alleles from the tolerant lines. After constructing a consensus map, three meta-QTL (mQTL) were identified to include at least two initial QTL from different populations. mQTL1-1 included seven initial QTL for both germination and seedling traits; with three explaining more than 30% phenotypic variance. mQTL2-1 and mQTL9-1 covered two to three initial QTL. The favorable alleles of the QTL within these three mQTL regions were all inherited from the tolerant line 220 and P9-10. These results provided a basis for cloning of genes underlying the mQTL regions to uncover the molecular mechanisms of maize cold tolerance during germination. PMID- 29445388 TI - Starch Hydrolysis and Vessel Occlusion Related to Wilt Symptoms in Olive Stems of Susceptible Cultivars Infected by Verticillium dahliae. AB - This study investigated starch content, amount of pathogen DNA and density of occluded vessels in healthy and Verticillium dahliae infected olive shoots and stems. Starch hydrolysis is considered a mechanism to refill xylem vessels that suffered cavitation by either, drought conditions or pathogen infections. The main objective of this work was to evaluate this mechanism in olive plants subjected to V. dahliae infection or to drought conditions, in order to know the importance of cavitation in the development of wilting symptoms. In initial experiments starch content in the shoots was studied in trees of cultivars differing in the level of resistance growing in fields naturally infested with V. dahliae. The starch content, esteemed by microscopic observation of stem transversal sections stained with lugol, decreased with the level of symptom severity. Results were confirmed in a new experiment developed with young plants of cultivars 'Picual' (highly susceptible), 'Arbequina' (moderately susceptible) and 'Frantoio' (resistant), growing in pots under greenhouse conditions, either inoculated or not with V. dahliae. In this experiment, the pathogen DNA content, quantified by real-time PCR, and the density of occluded vessels, recorded by microscopic observations of transversal sections stained with toluidine blue, were related to the symptoms severity caused by the pathogen. Finally, a drought experiment was established with young plants of the cultivar 'Picual' grown in pots under greenhouse conditions in order to compare the effects caused by water deficit with those caused by the pathogen infection. In both cases, results show that starch hydrolysis occurred, what indirectly evidence the importance of xylem cavitation in the development of the symptoms caused by V. dahliae but in the water stressed plants no vessel occlusion was detected. PMID- 29445389 TI - Interspecific Divergence of Two Sinalliaria (Brassicaceae) Species in Eastern China. AB - How endemic species originated in eastern Asia has interested botanists for a long time. In this study, we combined experimental and computational modeling approaches to examine the morphological and genetic divergence and reproductive isolation of two tentative species of Sinalliaria (Brassicaceae) endemic to eastern China, S. limprichtiana and S. grandifolia. Most of the examined morphological characters (including hairs of leaf blades and stems, corolla length and width, and flower stalk length) were well-delineated between two species at the same ploidy level, and there was clear evidence of reproductive isolation between them (mainly due to post-pollination barriers) in the common garden environment. There were also strong and consistent divergences in the population genetic data. Coalescent simulations based on sequence variation of the nuclear genes suggest that interspecific divergence began during the Pleistocene when the climate oscillated in eastern Asia. Gene flow between two species appears to have been very limited and asymmetrical. Our results suggested that both species are well-differentiated and that the fast divergence between them might have been together shaped by both stochastic processes and habitat selection pressures. PMID- 29445390 TI - Approaches and Recent Developments for the Commercial Production of Semi synthetic Artemisinin. AB - The antimalarial drug artemisinin is a natural product produced by the plant Artemisia annua. Extracts of A. annua have been used in Chinese herbal medicine for over two millennia. Following the re-discovery of A. annua extract as an effective antimalarial, and the isolation and structural elucidation of artemisinin as the active agent, it was recommended as the first-line treatment for uncomplicated malaria in combination with another effective antimalarial drug (Artemisinin Combination Therapy) by the World Health Organization (WHO) in 2002. Following the WHO recommendation, the availability and price of artemisinin fluctuated greatly, ranging from supply shortfalls in some years to oversupply in others. To alleviate these supply and price issues, a second source of artemisinin was sought, resulting in an effort to produce artemisinic acid, a late-stage chemical precursor of artemisinin, by yeast fermentation, followed by chemical conversion to artemisinin (i.e., semi-synthesis). Engineering to enable production of artemisinic acid in yeast relied on the discovery of A. annua genes encoding artemisinic acid biosynthetic enzymes, and synthetic biology to engineer yeast metabolism. The progress of this effort, which resulted in semi-synthetic artemisinin entering commercial production in 2013, is reviewed with an emphasis on recent publications and opportunities for further development. Aspects of both the biology of artemisinin production in A. annua, and yeast strain engineering are discussed, as are recent developments in the chemical conversion of artemisinic acid to artemisinin. PMID- 29445391 TI - ZIP13: A Study of Drosophila Offers an Alternative Explanation for the Corresponding Human Disease. AB - The fruit fly Drosophila melanogaster has become an important model organism to investigate metal homeostasis and human diseases. Previously we identified dZIP13 (CG7816), a member of the ZIP transporter family (SLC39A) and presumably a zinc importer, is in fact physiologically primarily responsible to move iron from the cytosol into the secretory compartments in the fly. This review will discuss the implication of this finding for the etiology of Spondylocheirodysplasia-Ehlers Danlos Syndrome (SCD-EDS), a human disease defective in ZIP13. We propose an entirely different model in that lack of iron in the secretory compartment may underlie SCD-EDS. Altogether three different working models are discussed, supported by relevant findings made in different studies, with uncertainties, and questions remained to be solved. We speculate that the distinct ZIP13 sequence features, different from those of all other ZIP family members, may confer it special transport properties. PMID- 29445392 TI - How many parathyroid glands can be identified during thyroidectomy?: Evidence based data for medical experts. AB - Background: The purpose of this study is to provide guidance for medical experts regarding malpractice claims on permanent hypoparathyroidism by analyzing the number of parathyroid glands (PGs) identified during thyroidectomy and the clinical outcome. Methods: Parathyroid findings were documented in a standardized protocol for 357 patients undergoing thyroidectomy and treated by a single specialized surgeon. The resected thyroid was routinely dissected for accidentally removed PGs with consecutive autotransplantation and the pathological report also described unintentionally resected PGs. Follow-up was performed for 6 months. Results: The mean number of identified PGs was 2.28. No PGs were found in 20 (5.6%), one in 56 (15.7%), two in 126 (35.3%), three in 114 (31.9%), and four in 41 (11.5%) cases. One patient (0.28%) had manifest permanent hypoparathyroidism, while ten patients (2.8%) had latent permanent hypoparathyroidism (hypocalcemia and normoparathyroidism). The risk factors identified for postoperative hypoparathyroidism were an increasing number of visualized PGs, autotransplantation, central neck dissection, and PGs in the histopathological work-up. For permanent hypoparathyroidism, PGs in the histology examination and neck dissection were significant, but the number of identified PGs was not. Conclusion: Even an experienced surgeon is not always able to find all four PGs during thyroidectomy and occasionally identifies none. Rather than focusing on identifying a minimum number of PGs, it is more important not to miss them in risky positions. A documented awareness of PGs, i. e., knowledge of variable parathyroid positions and their saving, is a prerequisite for surgical quality and to protect surgeons from claims. PMID- 29445393 TI - Adenoma and Polyp Detection Rates in Colonoscopy according to Indication. AB - Background: Adenoma detection rate (ADR) is a validated quality measure for screening colonoscopy, but there are little data for other indications. The distribution of adenomas is not well described for these indications. Aim: To describe ADR and the adenoma distribution in the proximal and distal colon based on colonoscopy indication. Methods: Outpatient colonoscopies are subdivided by indication. PDR and ADR for the entire colon and for proximal and distal colon. Data were compared using generalized estimating equations to adjust for clustering amongst endoscopists while controlling for patient age and gender. Results: 3436 colonoscopies were reviewed (51.2%: men (n = 1759)). Indications are screening 49.2%, surveillance 29.3%, change in bowel habit 8.4%, bleeding 5.8%, colitides 3.0%, pain 2.8%, and miscellaneous 1.5%. Overall ADR was 37% proximal ADR 28%, and distal ADR 17%. PDR and ADR were significantly higher in surveillance than in screening (PDR: 69% versus 51%; ADR: 50% versus 33%; p = 0.0001). Adenomas were more often detected in the proximal than in the distal colon, for all indications. Conclusions: Prevalence of polyps and adenomas differs based on colonoscopy indication. Adenoma detection is highest in surveillance and more commonly detected in the proximal colon. For quality assurance, distinct ADR and PDR targets may need to be established for different colonoscopy indications. PMID- 29445394 TI - Polyethylene Glycol for Small Bowel Capsule Endoscopy. AB - Capsule endoscopy has been the first-line examination for small bowel diseases, yet its diagnostic yield is restricted by unsatisfactory bowel preparation. To evaluate the clinical effectiveness of different dosages of polyethylene glycol in patients undergoing capsule endoscopy, we performed a comprehensive meta analysis of all randomized controlled trials involving polyethylene glycol in preparation for capsule endoscopy. The methodological quality of the trials was evaluated using the Cochrane Risk of Bias assessment instrument. In this study, 12 RCTs involving 2072 patients were included in this review. Our review indicated that 4 L and 2 L polyethylene (PEG) before capsule endoscopy (CE) and 500 mL PEG after CE increase the small bowel image quality, whereas 1 L PEG did not improve the small bowel image quality. PEG accelerated the gastric emptying time. There was no significant difference between the PEG group and control group in small bowel transit time, completion rates, and diagnostic yield. PMID- 29445395 TI - Platelet Distribution Width Levels Can Be a Predictor in the Diagnosis of Persistent Organ Failure in Acute Pancreatitis. AB - Purpose: The change of serum platelet indices such as platelet distribution width (PDW) has been reported in a series of inflammatory reaction and clinical diseases. However, the relationship between PDW and the incidence of persistent organ failure (POF) in acute pancreatitis (AP) has not been elucidated so far. Materials and Methods: A total of 135 patients with AP admitted within 72 hours from symptom onset of AP at our center between December 2014 and January 2016 were included in this retrospective study. Demographic parameters on admission, organ failure assessment, laboratory data, and in-hospital mortality were compared between patients with and without POF. Multivariable logistic regression analyses were utilized to evaluate the predictive value of serum PDW for POF. Results: 30 patients were diagnosed with POF. Compared to patients without POF, patients with POF showed a significantly higher value of serum PDW on admission (14.88 +/- 2.24 versus 17.60 +/- 1.96%, P < 0.001). After multivariable analysis, high PDW level remained a risk factor for POF (odds ratio 39.42, 95% CI: 8.64 179.77; P < 0.001). A PDW value of 16.45% predicted POF with an area under the curve (AUC) of 0.870, a sensitivity with 0.867, and a specificity with 0.771, respectively. Conclusions: Our results indicate that serum PDW on admission could be a predictive factor in AP with POF and may serve as a potential prognostic factor.

The area of abdominal subcutaneous adipose tissue (ASAT) and visceral adipose tissue (VAT) was measured and the ratio of ASAT to VAT (SVR) was calculated. Results: SVR was correlated positively with Matsuda index in healthy, MD, and hyperglycemia groups, and inversely with HOMA-IR. SVR positively related with both early- and late-phase DI in the healthy group only. In the healthy group, the hyperbolas of I0-30/G0-30 and I30-120/G30-120 versus Matsuda index in the highest quarter of SVR were significantly right shifted compared to those in the lowest (both P < 0.05). Conclusions: In healthy adults, higher SVR was a protective factor for beta-cell function and IS, while in those with glucometabolic abnormality, higher SVR contributed to a relative better IS, indicating SVR is possible to be an early predicator of type 2 diabetes development. PMID- 29445398 TI - A New Method for the Determination of Sucrose Concentration in a Pure and Impure System: Spectrophotometric Method. AB - Analytical chemistry is a set of procedures and techniques used to identify and quantify the composition of a sample of material. It is also focused on improvements in experimental design and the creation of new measurement tools. Analytical chemistry has broad applications to forensics, medicine, science, and engineering. The objective of this study is to develop a new method of sucrose dosage using a spectrophotometry method in a pure and impure system (presence of glucose and fructose). The work performed shows the reliability of this method. A model linking sucrose solution absorbance and mass percentage of glucose and fructose has been developed using experimental design. The results obtained show that all the investigated factors (sucrose concentration, mass percentage of glucose, and mass percentage of fructose) have a positive effect on the absorbance. The effect of the interaction between glucose and fructose on the absorbance is very significant.

AB - Background: Curcumin contained in Curcuma xanthorrhiza is an immunomodulator that has similar biological effect as vitamin D. Combination of curcumin and vitamin D3 is expected to work synergistically. Objective: To determine the effect of Curcuma xanthorrhiza supplementation on vitamin D3 administration to SLEDAI, IL 6, and TGF-beta1 serum in SLE patients with hypovitamin D. Methods: This was a double-blind RCT conducted in Saiful Anwar Hospital, Malang, in January 2016 March 2017. Subjects were SLE active (SLEDAI > 3) with levels of 25(OH)D3 <= 30 ng/ml and divided into two groups: those receiving cholecalciferol 3 * 400 IU and placebo 3 * 1 tablets (group I) and those receiving 3 * 400 IU cholecalciferol and Curcuma xanthorrhiza 3 * 20 mg for 3 months (group II). SLEDAI, levels of vitamin D, IL-6, and TGF-beta1 in serum were evaluated before and after the treatment. Results: There were no significant differences in SLEDAI reduction, decreased serum levels of IL-6, and increased levels of TGF-beta1 serum among groups after the treatment. Decreased levels of serum IL-6 have a positive correlation with SLEDAI reduction. Conclusion. Curcuma xanthorrhiza supplementation on vitamin D3 had no effects on SLEDAI and serum levels of IL-6 and TGF-beta1. This clinical trial is registered with NCT03155477. PMID- 29445399 TI - Nesprin-2 Interacts with Condensin Component SMC2. AB - The nuclear envelope proteins, Nesprins, have been primarily studied during interphase where they function in maintaining nuclear shape, size, and positioning. We analyze here the function of Nesprin-2 in chromatin interactions in interphase and dividing cells. We characterize a region in the rod domain of Nesprin-2 that is predicted as SMC domain (aa 1436-1766). We show that this domain can interact with itself. It furthermore has the capacity to bind to SMC2 and SMC4, the core subunits of condensin. The interaction was observed during all phases of the cell cycle; it was particularly strong during S phase and persisted also during mitosis. Nesprin-2 knockdown did not affect condensin distribution; however we noticed significantly higher numbers of chromatin bridges in Nesprin-2 knockdown cells in anaphase. Thus, Nesprin-2 may have an impact on chromosomes which might be due to its interaction with condensins or to indirect mechanisms provided by its interactions at the nuclear envelope. PMID- 29445401 TI - Predictors of Women's Satisfaction with Hospital-Based Intrapartum Care in Asmara Public Hospitals, Eritrea. AB - Background: Exploring patient satisfaction contributes to provide quality maternity care, but there is paucity of epidemiologic data in Eritrea. Objectives: To determine the predictors of women's satisfaction with intrapartum care in Asmara public maternity hospitals in Eritrea. Methods: A cross-sectional study among 771 mothers who gave birth in three public Hospitals. Chi-square tests were done to analyze the difference in proportion and logistic regression to assess the predictors of satisfaction with intrapartum care. Results: Overall, only 20.8% of the participants were satisfied with intrapartum service. The key predictors of satisfaction with intrapartum care were provision of clean bed and beddings (AOR = 18.87, 2.33-15.75), privacy during examinations (AOR = 10.22, 4.86-21.48), using understandable language (AOR = 8.72, 3.57-21.27), showing how to summon for help (AOR = 8.16, 4.30-15.48), showing baby immediately after birth (AOR = 8.14, 2.87-23.07), control of the delivery room (AOR = 6.86, 2.65-17.75), receiving back massage (AOR = 6.43, 3.23-12.81), toilet access and cleanliness (AOR = 6.09, 3.25-11.42), availability of chairs for relatives (AOR = 5.96, 3.14 11.30), allowing parents to stay during labour (AOR = 3.52, 1.299-9.56), and request for permission before any procedure (AOR = 2.39, 1.28-4.46). Conclusion: To increase satisfaction with intrapartum care, maternity service providers need to address the general maternity ward cleanliness, improve the quality of physical facilities, and sensitize health providers for better communication with clients. Policy makers need to adopt strategies that ensure more women involvement in decision making and consideration of privacy and reassurance needs during the whole delivery process. PMID- 29445402 TI - Allogenic Adipose Tissue-Derived Mesenchymal Stem Cells Ameliorate Acute Hepatic Injury in Dogs. AB - Adipose tissue-derived mesenchymal stem cells (AT-MSCs) are an attractive source for cell-based therapy of some diseases, including acute and chronic liver failure, in not only human medicine but also veterinary medicine. However, in veterinary medicine, no studies have reported the effects of AT-MSCs on liver injury in dogs. The purpose of this study was to investigate the effects of allogenic AT-MSCs on acute liver injury by carbon tetrachloride in dogs and to compare the therapeutic effects of AT-MSCs transplanted via the peripheral vein (PV) or splenic vein (SV). After transplantation of AT-MSCs through the PV or SV, serum liver enzymes were decreased significantly, and SV injection was more effective compared with PV injection. By comparing the number of engrafted AT MSCs in the liver, SV injection was significantly more effective than PV injection. mRNA expression levels of proinflammatory cytokines, such as IL-1, IL 6, IL-8, and IFNgamma, in the liver were decreased significantly, but those of anti-inflammatory cytokines, such as IL-4 and IL-10, HGF, and VEGFA, were significantly increased after the first AT-MSC injection. These findings suggest that allogenic AT-MSCs injected via the PV or SV ameliorate acute hepatic injury in dogs, and AT-MSCs injected via the SV provide more effective improvement. PMID- 29445403 TI - Reversal of Experimental Liver Damage after Transplantation of Stem-Derived Cells Detected by FTIR Spectroscopy. AB - The transplantation of autologous BM-MSCs holds great potential for treating end stage liver diseases. The aim of this study was to compare the efficiency of transplanted rBM-MSCs and rBM-MSC-derived differentiated stem cells (rBM-MSC DSCs) for suppression of dimethylnitrosamine-injured liver damage in rat model. Synchrotron radiation Fourier-transform infrared (SR-FTIR) microspectroscopy was applied to investigate changes in the macromolecular composition. Transplantation of rBM-MSC-DSCs into liver-injured rats restored their serum albumin level and significantly suppressed transaminase activity as well as the morphological manifestations of liver disease. The regenerative effects of rBM-MSC-DSCs were corroborated unequivocally by the phenotypic difference analysis between liver tissues revealed by infrared spectroscopy. Spectroscopic changes in the spectral region from 1190-970 cm-1 (bands with absorbance maxima at 1150 cm-1, 1081 cm-1, and 1026 cm-1) indicated decreased levels of carbohydrates, in rBM-MSC-DSC transplanted livers, compared with untreated and rBM-MSC--transplanted animals. Principal component analysis (PCA) of spectra acquired from liver tissue could readily discriminate rBM-MSC-DSC-transplanted animals from the untreated and rBM MSC-transplanted animals. We conclude that the transplantation of rBM-MSC-DSCs effectively treats liver disease in rats and SR-FTIR microspectroscopy provides important insights into the fundamental biochemical alterations induced by the stem-derived cell transplantation, including an objective "signature" of the regenerative effects of stem cell therapy upon liver injury.

PMID- 29445405 TI - High Sensitivity of Human Adipose Stem Cells to Differentiate into Myofibroblasts in the Presence of C. aspersa Egg Extract. AB - Introduction: Regeneration therapy using adipose-derived stem cells (ADSC) has been proposed in the treatment of skin aging. Myofibroblast plays a relevant role in the organization of the extracellular matrix of the damaged skin. A natural extract was derived from the eggs of the mollusk Cryptomphalus aspersa (e-CAF) that seems to play a role on skin repair. We have investigated the potential effects of e-CAF in the differentiation of ADSC. Materials and methods: ADSC were cultured in the absence or presence of e-CAF (50 and 200 MUg/mL) for 24 hours and 7 days. Real-time cell assay, morphological, immunofluorescence, and RT-PCR techniques were used to evaluate the cell culture and expression of alphaSMA, collagen I, and tropoelastin. Results: e-CAF induced significant reduction in the rate of growth of ADSC from 24 hours to 7 days of culture. e-CAF also induced bigger sizes, higher levels of cytoplasmic refringence and complexity, and a more polyhedral morphological changes in the cultured ADSC. The protein and mRNA expression of alphaSMA was significantly increased in e-CAF-cultured ADSC. Conclusion: e-CAF promotes ADSC differentiation to myofibroblasts and should be considered as a potential agent for the prevention and treatment of skin aging. PMID- 29445406 TI - Detection and Molecular Characterization of Human Adenovirus Infections among Hospitalized Children with Acute Diarrhea in Shanghai, China, 2006-2011. AB - Background: Human adenovirus (HAdV) is considered a significant enteropathogen associated with sporadic diarrhea in children. However, limited data are available regarding the epidemiology of HAdV in hospitalized children with viral diarrhea in Shanghai. The aim of this study was to characterize the epidemiology of HAdVs and describe their association with acute diarrhea in hospitalized children. Methods: A total of 674 fecal samples were subjected to PCR or RT-PCR to detect RVA, HuCV, HAstV, and HAdV. Results: HAdV infections were detected in 4.7% (32/674) of specimens, with detection rates of 13.4% (11/82), 4.6% (8/174), 3.2% (4/124), 4.1% (3/74), 2.0% (2/100), and 3.3% (4/120) from 2006 to 2011, respectively. Comprehensive detection of the four viruses revealed the presence of a high percentage (90.6%) of coinfections among HAdV-positive samples, where HAdV+RVA was the most prevalent coinfection. Of the 32 HAdV-positive samples, 50.0% (16/32) were classified as HAdV-41, and 18.8% (6/32) were classified as HAdV-3. Almost 94.0% of children infected with HAdV were less than 24 months of age. Conclusions: These results clearly indicated diversity across the HAdV genotypes detected in inpatient children with acute diarrhea in Shanghai and suggested that HAdVs play a role in children with acute diarrhea. PMID- 29445407 TI - Practical outpatient pharmacotherapy for alcohol use disorder. AB - Alcohol use disorder (AUD) is commonly encountered in clinical practice. A combination of psychosocial intervention and pharmacotherapy is the cornerstone of AUD treatment. Despite their efficacy, safety and cost-effectiveness, clinicians are reluctant to prescribe medications to treat individuals with AUD. Given the high rate of relapse with psychosocial intervention alone, increasing patient access to this underutilized treatment has the potential to improve clinical outcome in this difficult-to-treat population. Herein, we provide practical pharmacotherapy strategies to improve treatment outcome for AUD. We review the efficacy and side effects of both on- and off-label agents with a particular focus on clinical applicability. Recommendations are supported by findings from randomized controlled trials (RCT) and meta-analyses selected to be representative, where possible, of current treatment guidelines. The goal of this paper is to help readers use pharmacotherapy with greater confidence when treating patients with AUD. PMID- 29445408 TI - Needs and preferences of women users of oral contraceptives in selected countries in Central and Eastern Europe. AB - Background: The availability of various oral contraceptive (OC) pill formulations with different hormone compositions suggests that there is potential to align a particular product with an individual user's needs and preferences. To explore this concept further, a survey was conducted of current users of OCs to define and confirm areas of specific needs, and to gain insight into their views and preferences for OC formulations. Methods: During November and December 2015, women users (n=615) of OCs in five Central and Eastern European countries were surveyed in face-to-face interviews conducted by experienced interviewers. The survey questionnaire comprised 34 questions about the use of and specific needs for OCs. Results: Four basic needs of women taking OCs were identified: reliable contraception, reversibility of contraception, no effect on body weight and safety. Overall, 85% of surveyed women indicated that prevention of pregnancy was the main reason for taking OCs. Weight gain was the side effect of greatest concern with OC use (46% spontaneous answer; 65% aided answer). Independent behavioural segmentation analysis identified four groups - Solved Cycle Problems (46% of participants), Low Hormone Content (22%), Lifestyle (17%) and Beauty (14%) - which characterised the women according to needs and preferences beyond the basic needs of OCs. Each group had unique features and distinct preferences for different formulations of OCs. Conclusions: Aligning product advantages with specific individual needs may enhance users' overall experience with OCs as a contraceptive option. PMID- 29445409 TI - Suvorexant for insomnia in older adults: a perspective review. AB - The aim of this review was to identify published randomized control trials (RCTs) that evaluated the efficacy and tolerability of suvorexant for the treatment of insomnia among older adults (>=65 years). A literature search was conducted of PubMed, MEDLINE, EMBASE, PsycINFO and Cochrane collaboration databases for RCTs in any language evaluating suvorexant for the treatment of insomnia in older adults. Additionally, references of full-text articles that were included in this review were searched for further studies. Data from three RCTs of suvorexant were included in this review. All the three studies fulfilled the criteria for being of good quality based on the items listed by the Center for Evidence Based Medicine (CEBM) for the assessment of RCTs. None of the three studies were conducted exclusively among older adults. However, they also included older individuals diagnosed with primary insomnia. These studies included a total of 1298 participants aged >=65 years in age. Trial durations ranged from 3 months to 1 year. Available data from these studies indicate that suvorexant improves multiple subjective and polysomnographic sleep parameters for sleep onset and maintenance among older individuals with a diagnosis of primary insomnia and is generally well tolerated. Current evidence, although limited, indicates that suvorexant benefits older adults with primary insomnia and is generally well tolerated. PMID- 29445410 TI - Enrichment of Phenolic Compounds from Olive Mill Wastewater and In Vitro Evaluation of Their Antimicrobial Activities. AB - The production of olive oil generates massive quantities of by-product called olive mill wastewater (OMWW). The uncontrolled disposal of OMWW poses serious environmental problems. The OMWW effluent is rich in several polyphenolic compounds. Liquid-liquid extraction of OMWW using ethyl acetate solvent was used to enrich phenolic compounds under investigation. Total phenolic and flavonoid content and antioxidant activity of the extract were determined. HPLC coupled to photodiode array (PDA) detector was used to analyze the main three phenolic compounds of OMWW, namely, hydroxytyrosol, tyrosol, and oleuropein. The antimicrobial activity of the extract was also investigated. Additionally, the OMWW extract was used as natural preservative and antioxidants for olive oil. Results showed that OMWW is very rich in phenolic compounds and has strong antioxidant activity. HPLC analysis showed that the extract contains mainly hydroxytyrosol and tyrosol but no oleuropein. The OMWW extract showed also positive activities as antibacterial (gram positive and gram negative) and antifungal as well as activities against yeast. The addition of OMWW extract to olive oil samples has an effect on the stability of olive oil as reflected by its acid value, peroxide value, K232 and K270, and total phenolic content. PMID- 29445411 TI - Memory Improvement Effect of Ethanol Garlic (A. sativum) Extract in Streptozotocin-Nicotinamide Induced Diabetic Wistar Rats Is Mediated through Increasing of Hippocampal Sodium-Potassium ATPase, Glutamine Synthetase, and Calcium ATPase Activities. AB - Studies suggest that garlic (A. sativum) improves memory dependent on the hippocampus. However, the effect of ethanol garlic extract on hippocampus Na+/K+ ATPase, Ca2+ ATPase, and glutamine synthetase (GS) activities as possible mechanisms in memory improvement in diabetic Wistar rats has not been reported. Twenty-four male Wistar rats weighing 200-250 g were divided into three groups with 8 rats each. Group (A), normal control rats, and Group (B), diabetic rats, received 1 ml of normal saline; diabetic rats in Group (C) received 1000 mg/kg of garlic extract orally for 21 days. Hyperglycemia was induced by a single intraperitoneal injection of streptozotocin 60 mg/kg followed by 120 mg/kg nicotinamide while extraction of garlic was done by cold maceration method. Memory was tested in all groups. After that, the rats were sacrificed, the brain was removed, and the hippocampi were carefully excised and then homogenized. Activities of Na+/K+ ATPase, calcium ATPase, and GS were analyzed from the homogenate. Results showed improvement in memory and a significant increase (P < 0.05) in hippocampus Na+/K+ ATPase, Ca2+ ATPase, and GS activities in diabetic rats treated with garlic extract. In conclusion, the increased activity of hippocampus Na+/K+ ATPase, calcium ATPase, and glutamine synthetase may account for the memory improvement. PMID- 29445412 TI - Aqueous Extracts of Herba Cistanche Promoted Intestinal Motility in Loperamide Induced Constipation Rats by Ameliorating the Interstitial Cells of Cajal. AB - Traditional Chinese medicine was reported to have good effects in treating functional constipation. This work attempted to prove the effects of aqueous extracts of Herba Cistanche (AEHC) on STC treatment and to determine the possible mechanisms by a loperamide-induced slow transit constipation (STC) model. HPLC was performed for identification and confirmation of the bioactive components in the AEHC. It was found that AEHC attenuated STC responses based on increased fecal quantity, moisture content, and intestinal transit rate, as well as serum levels of GAS, MTL, SS, and CGRP. The protein and mRNA levels of c-kit, a labeling of interstitial cells of Cajal (ICC), also increased. Meanwhile, only the protein level of SCF, a ligand of c-kit, increased. The analysis of our data suggested that AEHC could obviously improve the function of ICC via a signaling pathway involving PI3K, SCF, and c-kit and enhance colonic motility indices such as GAS, MTL, SS, and CGRP. It is interesting to note that AEHC appeared to be effective on constipation, so further experiments are necessary to clarify the exact mechanisms involved. PMID- 29445413 TI - Icariin Regulates the Bidirectional Differentiation of Bone Marrow Mesenchymal Stem Cells through Canonical Wnt Signaling Pathway. AB - Fat infiltration within the bone marrow is easily observed in some postmenopausal women. Those fats are mainly derived from bone marrow mesenchymal stem cells (BMMSCs). The increment of adipocytes derived from BMMSCs leads to decreased osteoblasts derived from BMMSCs, so the bidirectional differentiation of BMMSCs significantly contributes to osteoporosis. Icariin is the main extractive of Herba Epimedii which is widely used in traditional Chinese medicine. In this experiment, we investigated the effect of icariin on the bidirectional differentiation of BMMSCs through quantitative real-time PCR, immunofluorescence, western blot, and tissue sections in vitro and in vivo. We found that icariin obviously promotes osteogenesis and inhibits adipogenesis through detecting staining and gene expression. Micro-CT analysis showed that icariin treatment alleviated the loss of cancellous bone of the distal femur in ovariectomized (OVX) mice. H&E staining analysis showed that icariin-treated OVX mice obtained higher bone mass and fewer bone marrow lipid droplets than OVX mice. Western blot and immunofluorescence showed that icariin regulates the bidirectional differentiation of BMMSCs via canonical Wnt signaling. This study demonstrates that icariin exerts its antiosteoporotic effect by regulating the bidirectional differentiation of BMMSCs through the canonical Wnt signaling pathway. PMID- 29445414 TI - Effects of a new nutraceutical combination on cognitive function in hypertensive patients. AB - Background: Chronic increased arterial blood pressure has been associated with executive dysfunction, slowing of attention and mental processing speed, and later with memory deficits. Due to the absence of a concrete therapeutic approach to this pathophysiological process, in the last decades there has been an increasing interest in the use of nutraceuticals, especially those with antioxidant properties, which own strong neuroprotective potential, that may help to improve cognitive function and to delay the onset of dementia. Results: We evaluated the effects of the treatment with a new nutraceutical preparation containing different molecules with potent antioxidant properties (AkP05, IzzeK(r)) and placebo on a cohort of thirty-six hypertensive patients. At baseline, neuropsychological evaluation, arterial stiffness and biochemical parameters of the subjects were comparable. After 6 months of treatment, there was a significant reduction of the augmentation index in the AkP05-treated group. Moreover, the measurement of cognitive function, evaluated with MoCA test and Word Match Testing, showed a significant improvement in patients receiving the active treatment. In addition, the group treated with nutraceutical reached a better Stroop test score, while subjects that received placebo did not showed any improvement. Finally, a positive relationship between SBP variation and the psychometric assessment with the EQ-VAS scale was observed only in the active treatment group. Conclusions: In this study, we demonstrated that the therapy with a new nutraceutical preparation is able to significantly increase the scores of important neuropsychological tests in hypertensive patients already on satisfactory blood pressure control. Although future studies are needed to better characterize the molecular mechanisms involved, these results candidate the new nutraceutical combination as a possible therapeutic strategy to support the cerebrovascular functions and delay the onset of dementia in hypertensive patients. PMID- 29445415 TI - Curcumin and piperine supplementation of obese mice under caloric restriction modulates body fat and interleukin-1beta. AB - Background: Dietary bioactive compounds capable of improving metabolic profiles would be of great value, especially for overweight individuals undergoing a caloric restriction (CR) regimen. Curcumin (Cur), a possible anti-obesity compound, and piperine (Pip), a plausible enhancer of Cur's bioavailability and efficacy, may be candidate agents for controlling body fat, metabolism and low grade inflammation. Methods: 47 eight-week-old male C57BL/6 mice were fed a high fat diet (HFD) for 23 weeks to induce obesity. Then, mice were divided into 5 groups. Group 1 continued on HFD ad libitum. The other 4 groups underwent CR (reduced 10% HFD intake for 10 weeks, 20% for 20 weeks) with Cur, Pip, Cur + Pip or none of these. Percent body fat, plasma inflammatory markers associated with obesity (interferon (IFN)-gamma, interleukin (IL)-10, IL-12 p70, IL-1beta, IL-6 and KC/GRO), plasma Cur metabolites and liver telomere length were measured. Results: Compared to the other groups, obese mice who underwent CR and received Cur + Pip in their diet lost more fat and had significantly lower IL-1beta and KC/GRO. Tandem mass spectrometry analysis of plasma from obese mice under CR showed no difference in Cur metabolite levels between groups supplemented with Cur alone or combined with Pip. However, plasma IL-1beta levels were inversely correlated with curcumin glucuronide. Minor modulation of telomere length were observed. Conclusions: It is plausible that supplementing the high fat diet of CR mice with Cur + Pip may increase loss of body fat and suppresses HFD induced inflammation. Combination of Cur and Pip has potential to enhance CR effects for the prevention of metabolic syndrome. PMID- 29445416 TI - A safe and complete algorithm for metagenomic assembly. AB - Background: Reconstructing the genome of a species from short fragments is one of the oldest bioinformatics problems. Metagenomic assembly is a variant of the problem asking to reconstruct the circular genomes of all bacterial species present in a sequencing sample. This problem can be naturally formulated as finding a collection of circular walks of a directed graph G that together cover all nodes, or edges, of G. Approach: We address this problem with the "safe and complete" framework of Tomescu and Medvedev (Research in computational Molecular biology-20th annual conference, RECOMB 9649:152-163, 2016). An algorithm is called safe if it returns only those walks (also called safe) that appear as subwalk in all metagenomic assembly solutions for G. A safe algorithm is called complete if it returns all safe walks of G. Results: We give graph-theoretic characterizations of the safe walks of G, and a safe and complete algorithm finding all safe walks of G. In the node-covering case, our algorithm runs in time [Formula: see text], and in the edge-covering case it runs in time [Formula: see text]; n and m denote the number of nodes and edges, respectively, of G. This algorithm constitutes the first theoretical tight upper bound on what can be safely assembled from metagenomic reads using this problem formulation. PMID- 29445418 TI - Local constructions of gender-based violence amongst IDPs in northern Uganda: analysis of archival data collected using a gender- and age-segmented participatory ranking methodology. AB - Background: Gender-based violence (GBV) is a significant problem in conflict affected settings. Understanding local constructions of such violence is crucial to developing preventive and responsive interventions to address this issue. Methods: This study reports on a secondary analysis of archived data collected as part of formative qualitative work - using a group participatory ranking methodology (PRM) - informing research on the prevalence of GBV amongst IDPs in northern Uganda in 2006. Sixty-four PRM group discussions were held with women, with men, with girls (aged 14 to 18 years), and with boys (aged 14 to 18 years) selected on a randomized basis across four internally displaced persons (IDP) camps in Lira District. Discussions elicited problems facing women in the camps, and - through structured participatory methods - consensus ranking of their importance and narrative accounts explaining these judgments. Results: Amongst forms of GBV faced by women, rape was ranked as the greatest concern amongst participants (with a mean problem rank of 3.4), followed by marital rape (mean problem rank of 4.5) and intimate partner violence (mean problem rank of 4.9). Girls ranked all forms of GBV as higher priority concerns than other participants. Discussions indicated that these forms of GBV were generally considered normalized within the camp. Gender roles and power, economic deprivation, and physical and social characteristics of the camp setting emerged as key explanatory factors in accounts of GBV prevalence, although these played out in different ways with respect to differing forms of violence. Conclusions: All groups acknowledged GBV to represent a significant threat - among other major concerns such as transportation, water, shelter, food and security - for women residing in the camps. Given evidence of the significantly higher risk in the camp of intimate partner violence and marital rape, the relative prominence of the issue of rape in all rankings suggests normalization of violence within the home. Programs targeting reduction in GBV need to address community-identified root causes such as economic deprivation and social norms related to gender roles. More generally, PRM appears to offer an efficient means of identifying local constructions of prevailing challenges in a manner that can inform programming. PMID- 29445417 TI - Bioactive polysaccharides from natural resources including Chinese medicinal herbs on tissue repair. AB - Background: Functional polysaccharides can be derived from plants (including herbs), animals and microorganisms. They have been widely used in a broad of biomedical applications, such as immunoregulatory agents or drug delivery vehicles. In the past few years, increasing studies have started to develop natural polysaccharides-based biomaterials for various applications in tissue engineering and regenerative medicine. Main body: We discuss in this article the emerging applications of natural polysaccharides-particularly those derived from Chinese medicine-for wound healing. First, we introduce natural polysaccharides of three natural sources and their biological activities. Then, we focus on certain natural polysaccharides with growth factor-binding affinities and their inspired polymeric tools, with an emphasis on how these polysaccharides could possibly benefit wound healing. Finally, we report the latest progress in the discovery of polysaccharides from Chinese medicinal herbs with identified activities favouring tissue repair. Conclusion: Natural polysaccharides with clearly elucidated compositions/structures, identified cellular activities, as well as desirable physical properties have shown the potential to serve as therapeutic tools for tissue regeneration. PMID- 29445419 TI - Highly efficient conversion of plant oil to bio-aviation fuel and valuable chemicals by combination of enzymatic transesterification, olefin cross metathesis, and hydrotreating. AB - Background: The production of fuels and chemicals from renewable resources is increasingly important due to the environmental concern and depletion of fossil fuel. Despite the fast technical development in the production of aviation fuels, there are still several shortcomings such as a high cost of raw materials, a low yield of aviation fuels, and poor process techno-economic consideration. In recent years, olefin metathesis has become a powerful and versatile tool for generating new carbon-carbon bonds. The cross-metathesis reaction, one kind of metathesis reaction, has a high potential to efficiently convert plant oil into valuable chemicals, such as alpha-olefin and bio-aviation fuel by combining with a hydrotreatment process. Results: In this research, an efficient, four-step conversion of plant oil into bio-aviation fuel and valuable chemicals was developed by the combination of enzymatic transesterification, olefin cross metathesis, and hydrotreating. Firstly, plant oil including oil with poor properties was esterified to fatty acid methyl esters by an enzyme-catalyzed process. Secondly, the fatty acid methyl esters were partially hydrotreated catalytically to transform poly-unsaturated fatty acid such as linoleic acid into oleic acid. The olefin cross-metathesis then transformed the oleic acid methyl ester (OAME) into 1-decene and 1-decenoic acid methyl ester (DAME). The catalysts used in this process were prepared/selected in function of the catalytic reaction and the reaction conditions were optimized. The carbon efficiency analysis of the new process illustrated that it was more economically feasible than the traditional hydrotreatment process. Conclusions: A highly efficient conversion process of plant oil into bio-aviation fuel and valuable chemicals by the combination of enzymatic transesterification, olefin cross-metathesis, and hydrotreatment with prepared and selected catalysts was designed. The reaction conditions were optimized. Plant oil was transformed into bio-aviation fuel and a high value alpha-olefin product with high carbon utilization. PMID- 29445420 TI - A bionic system with Fenton reaction and bacteria as a model for bioprocessing lignocellulosic biomass. AB - Background: The recalcitrance of lignocellulosic biomass offers a series of challenges for biochemical processing into biofuels and bio-products. For the first time, we address these challenges with a biomimetic system via a mild yet rapid Fenton reaction and lignocellulose-degrading bacterial strain Cupriavidus basilensis B-8 (here after B-8) to pretreat the rice straw (RS) by mimicking the natural fungal invasion process. Here, we also elaborated the mechanism through conducting a systematic study of physicochemical changes before and after pretreatment. Results: After synergistic Fenton and B-8 pretreatment, the reducing sugar yield was increased by 15.6-56.6% over Fenton pretreatment alone and 2.7-5.2 times over untreated RS (98 mg g-1). Morphological analysis revealed that pretreatment changed the surface morphology of the RS, and the increase in roughness and hydrophilic sites enhanced lignocellulose bioavailability. Chemical components analyses showed that B-8 removed part of the lignin and hemicellulose which caused the cellulose content to increase. In addition, the important chemical modifications also occurred in lignin, 2D NMR analysis of the lignin in residues indicated that the Fenton pretreatment caused partial depolymerization of lignin mainly by cleaving the beta-O-4 linkages and by demethoxylation to remove the syringyl (S) and guaiacyl (G) units. B-8 could depolymerize amount of the G units by cleaving the beta-5 linkages that interconnect the lignin subunits. Conclusions: A biomimetic system with a biochemical Fenton reaction and lignocellulose-degrading bacteria was confirmed to be able for the pretreatment of RS to enhance enzymatic hydrolysis under mild conditions. The high digestibility was attributed to the destruction of the lignin structure, partial hydrolysis of the hemicellulose and partial surface oxidation of the cellulose. The mechanism of synergistic Fenton and B-8 pretreatment was also explored to understand the change in the RS and the bacterial effects on enzymatic hydrolysis. Furthermore, this biomimetic system offers new insights into the pretreatment of lignocellulosic biomass.

AB - Background: Nijmegen breakage syndrome is an autosomal recessive disorder characterized by microcephaly, immunodeficiency, hypersensitivity to X irradiation, and a high predisposition to cancer. Nibrin, the product of the NBN gene, is part of the MRE11/RAD50 (MRN) complex that is involved in the repair of DNA double strand breaks (DSBs), and plays a critical role in the processing of DSBs in immune gene rearrangements, telomere maintenance, and meiotic recombination. NBS skin fibroblasts grow slowly in culture and enter early into senescence. Case presentation: Here we present an incidental finding. Skin fibroblasts, derived from a 9 year old NBS patient, showed a mosaic of normal diploid cells (46,XY) and those with a complex, unbalanced translocation. The aberrant karyotype was analysed by G-banding, comparative genomic hybridization, and whole chromosome painting. The exact breakpoints of the derivative chromosome were mapped by whole genome sequencing: 45,XY,der(6)(6pter -> 6q11.1::13q11 -> 13q21.33::20q11.22 -> 20qter),-13. The deleted region of chromosomes 6 harbors almost 1.400 and that of chromosome 13 more than 500 genes, the duplicated region of chromosome 20 contains about 700 genes. Such unbalanced translocations are regularly incompatible with cellular survival, except in malignant cells. The aberrant cells, however, showed a high proliferation potential and could even be clonally expanded. Telomere length was significantly reduced, hTERT was not expressed. The cells underwent about 50 population doublings until they entered into senescence. The chromosomal preparation performed shortly before senescence showed telomere fusions, premature centromere divisions, endoreduplications and tetraploid cells, isochromatid breaks and a variety of marker chromosomes. Inspection of the site of skin biopsy 18 years later, presented no evidence for abnormal growth. Conclusions: The aberrant cells had a significant selective advantage in vitro. It is therefore tempting to speculate that this highly unbalanced translocation could be a primary driver of cancer cell growth. PMID- 29445422 TI - Sleeping Beauty transposon integrates into non-TA dinucleotides. AB - Background: Sleeping Beauty transposon (SB) has become an increasingly important genetic tool for generating mutations in vertebrate cells. It is widely thought that SB exclusively integrates into TA dinucleotides. However, this strict TA preference has not been rigorously tested in large numbers of insertion sites that now can be detected with next generation sequencing. Li et al. found 71 SB insertions in non-TA dinucleotides in 2013, suggesting that TA dinucleotides are not the only sites of SB integration, yet further studies on this topic have not been carried out. Results: In this study, we re-analyzed 600 million pairs of Illumina sequence reads from a high-throughput SB mutagenesis screen and identified 28 thousand SB insertions in non-TA sites. We recovered some of these non-TA sites using PCR and confirmed that at least a subset of the insertions at non-TA sites are real integrations. The consensus sequence of these non-TA sites shows an asymmetric pattern distinct from the symmetric pattern of the canonical TA sites. Perfect similarity between the downstream flanking sequence and SB transposon ends indicates there may be interaction between the transposon DNA binding domain of transposase and the target DNA. Conclusion: The TA-preference of SB transposon is not as strict as what people had thought. And the SB integrations at non-TA sites might be guided by the interaction between the transposon DNA binding domain of SB transposase and the target DNA. PMID- 29445423 TI - An update on vitamin B12-related gene polymorphisms and B12 status. AB - Background: Vitamin B12 is an essential micronutrient in humans needed for health maintenance. Deficiency of vitamin B12 has been linked to dietary, environmental and genetic factors. Evidence for the genetic basis of vitamin B12 status is poorly understood. However, advancements in genomic techniques have increased the knowledge-base of the genetics of vitamin B12 status. Based on the candidate gene and genome-wide association (GWA) studies, associations between genetic loci in several genes involved in vitamin B12 metabolism have been identified. Objective: The objective of this literature review was to identify and discuss reports of associations between single-nucleotide polymorphisms (SNPs) in vitamin B12 pathway genes and their influence on the circulating levels of vitamin B12. Methods: Relevant articles were obtained through a literature search on PubMed through to May 2017. An article was included if it examined an association of a SNP with serum or plasma vitamin B12 concentration. Beta coefficients and odds ratios were used to describe the strength of an association, and a P < 0.05 was considered as statistically significant. Two reviewers independently evaluated the eligibility for the inclusion criteria and extracted the data. Results: From 23 studies which fulfilled the selection criteria, 16 studies identified SNPs that showed statistically significant associations with vitamin B12 concentrations. Fifty-nine vitamin B12-related gene polymorphisms associated with vitamin B12 status were identified in total, from the following populations: African American, Brazilian, Canadian, Chinese, Danish, English, European ancestry, Icelandic, Indian, Italian, Latino, Northern Irish, Portuguese and residents of the USA. Conclusion: Overall, the data analyzed suggests that ethnic specific associations are involved in the genetic determination of vitamin B12 concentrations. However, despite recent success in genetic studies, the majority of identified genes that could explain variation in vitamin B12 concentrations were from Caucasian populations. Further research utilizing larger sample sizes of non-Caucasian populations is necessary in order to better understand these ethnic-specific associations. PMID- 29445425 TI - Mosaicism for GNAS methylation defects associated with pseudohypoparathyroidism type 1B arose in early post-zygotic phases. AB - Background: Pseudohypoparathyroidism type 1B (PHP1B; MIM#603233) is a rare imprinting disorder (ID), associated with the GNAS locus, characterized by parathyroid hormone (PTH) resistance in the absence of other endocrine or physical abnormalities. Sporadic PHP1B cases, with no known underlying primary genetic lesions, could represent true stochastic errors in early embryonic maintenance of methylation. Previous data confirmed the existence of different degrees of methylation defects associated with PHP1B and suggested the presence of mosaicism, a phenomenon already described in the context of other IDs. Results: With respect to mosaic conditions, the study of multiple tissues is a necessary approach; thus, we investigated somatic cell lines (peripheral blood and buccal epithelium and cells from the urine sediment) descending from different germ layers from 19 PHP patients (11 spor-PHP1B, 4 GNAS mutated PHP1A, and 4 PHP with no GNAS (epi)genetic defects) and 5 healthy controls. We identified 11 patients with epigenetic defects, further subdivided in groups with complete or partial methylation defects. The recurrence of specific patterns of partial methylation defects limited to specific CpGs was confirmed by checking methylation profiles of spor-PHP1B patients diagnosed in our lab (n = 56). Underlying primary genetic defects, such as uniparental disomy or deletion, potentially causative for the detected partial methylation were excluded in all samples. Conclusions: Our data showed no differences of methylation levels between organs and tissues from the same patient, so we concluded that the epimutation occurred in early post-zygotic phases and that the partial defects were mosaics. The number of patients with no detectable (epi)genetic GNAS defects was too small to exclude epimutations occurring in later post-zygotic phases, affecting only selected tissues different from blood, thus leading to underdiagnosis during routine molecular diagnosis. Finally, we found no correlation between methylation ratios, representing the proportion of epimutated cells, and the clinical presentation, further confirming the hypothesis of a threshold effect of the GNAS loss of imprinting leading to an "all-or-none" phenotype. PMID- 29445424 TI - Promoter methylation of DNA damage repair (DDR) genes in human tumor entities: RBBP8/CtIP is almost exclusively methylated in bladder cancer. AB - Background: Genome-wide studies identified pan-cancer genes and shared biological networks affected by epigenetic dysregulation among diverse tumor entities. Here, we systematically screened for hypermethylation of DNA damage repair (DDR) genes in a comprehensive candidate-approach and exemplarily identify and validate candidate DDR genes as targets of epigenetic inactivation unique to bladder cancer (BLCA), which may serve as non-invasive biomarkers. Methods: Genome-wide DNA methylation datasets (2755 CpG probes of n = 7819 tumor and n = 659 normal samples) of the TCGA network covering 32 tumor entities were analyzed in silico for 177 DDR genes. Genes of interest were defined as differentially methylated between normal and cancerous tissues proximal to transcription start sites. The lead candidate gene was validated by methylation-specific PCR (MSP) and/or bisulfite-pyrosequencing in different human cell lines (n = 36), in primary BLCA tissues (n = 43), and in voided urine samples (n = 74) of BLCA patients. Urines from healthy donors and patients with urological benign and malignant diseases were included as controls (n = 78). mRNA expression was determined using qRT-PCR in vitro before (n = 5) and after decitabine treatment (n = 2). Protein expression was assessed by immunohistochemistry (n = 42). R 3.2.0. was used for statistical data acquisition and SPSS 21.0 for statistical analysis. Results: Overall, 39 DDR genes were hypermethylated in human cancers. Most exclusively and frequently methylated (37%) in primary BLCA was RBBP8, encoding endonuclease CtIP. RBBP8 hypermethylation predicted longer overall survival (OS) and was found in 2/4 bladder cancer cell lines but not in any of 33 cancer cell lines from entities with another origin like prostate. RBBP8 methylation was inversely correlated with RBBP8 mRNA and nuclear protein expression while RBBP8 was re expressed after in vitro demethylation. RBBP8 methylation was associated with histological grade in primary BLCA and urine samples. RBBP8 methylation was detectable in urine samples of bladder cancer patients achieving a sensitivity of 52%, at 91% specificity. Conclusions: RBBP8 was identified as almost exclusively hypermethylated in BLCA. RBBP8/CtIP has a proven role in homologous recombination mediated DNA double-strand break repair known to sensitize cancer cells for PARP1 inhibitors. Since RBBP8 methylation was detectable in urines, it may be a complementary marker of high specificity in urine for BLCA detection. PMID- 29445426 TI - The effect of different methods and image analyzers on the results of the in vivo comet assay. AB - Introduction: The in vivo comet assay is a widely used genotoxicity test that can detect DNA damage in a range of organs. It is included in the Organisation for Economic Co-operation and Development Guidelines for the Testing of Chemicals. However, various protocols are still used for this assay, and several different image analyzers are used routinely to evaluate the results. Here, we verified a protocol that largely contributes to the equivalence of results, and we assessed the effect on the results when slides made from the same sample were analyzed using two different image analyzers (Comet Assay IV vs Comet Analyzer). Findings: Standardizing the agarose concentrations and DNA unwinding and electrophoresis times had a large impact on the equivalence of the results between the different methods used for the in vivo comet assay. In addition, there was some variation in the sensitivity of the two different image analyzers tested; however this variation was considered to be minor and became negligible when the test conditions were standardized between the two different methods. Conclusion: By standardizing the concentrations of low melting agarose and DNA unwinding and electrophoresis times between both methods used in the current study, the sensitivity to detect the genotoxicity of a positive control substance in the in vivo comet assay became generally comparable, independently of the image analyzer used. However, there may still be the possibility that other conditions, except for the three described here, could affect the reproducibility of the in vivo comet assay. PMID- 29445427 TI - A Novel Open-Framework Cu-Ge-Based Chalcogenide Anode Material for Sodium-Ion Battery. AB - Open-framework chalcogenides are potential electrode materials for sodium-ion batteries (SIBs) due to their architectures with fast-ion conductivity. Herein, we report on the successful synthesis of open-framework Cu-Ge-based chalcogenides [Cu8Ge6Se19](C5H12N)6 (CGSe) and the research of their energy storage application as SIB anodes for the first time. As a result, the CGSe anode exhibited good electrochemical performances such as high reversible capacity (463.3 mAh g-1), excellent rate performance, and considerable cycling stability. Our exploration not only develops a promising electrode material for SIBs, but also extends the application of open-framework chalcogenides. PMID- 29445428 TI - The Danger Zone in the Anterior Neck: Anatomical Landmarks to Avoid Injury to Anterior Jugular Vein During Face-Lift and Neck-Lift. AB - Background: An estimated 125,711 face-lifts and 54,281 neck-lifts were performed in 2015. Regardless of the technique employed, facial and neck flap elevation carries with it anatomical risk of which any surgeon performing these procedures should be aware of. Statistics related to anterior jugular vein injury during these procedures have not been published. Objective: To define a "danger zone" that will contain both of the anterior jugular veins on the basis of anatomical landmarks to aid surgeons with planning their surgical approach during rhytidectomy in the anterior neck region. Methods: Ten fresh tissue heminecks were dissected. All specimens were dissected under loupe magnification in a 45 degrees (face-lift) position in which a midline incision was used for exposure. Measurements from the anterior jugular vein to the hyoid, thyroid cartilage, and cricoid cartilage bilaterally were taken. The transverse distance between the anterior jugular veins at the level of the hyoid, thyroid cartilage, and cricoid cartilage was also measured. Results: The anterior jugular veins remain in an anatomical danger zone while they travel in the anterior neck. Regardless of anatomical variation of the vessels between bodies, they generally reside in this danger zone from their inferior emergence behind the sternocleidomastoid muscle until they branch in the suprahyoid region. Conclusions: Knowledge of the anatomy, course, and location of the anterior jugular veins through the anterior neck based on anatomical landmarks and distance ratios can facilitate a safer dissection during rhytidectomy procedures. PMID- 29445429 TI - Classification of MRI and psychological testing data based on support vector machine. AB - Alzheimer's disease (AD) is a progressive, and often fatal, brain disease that causes neurodegeneration, resulting in memory loss as well as other cognitive and behavioral problems. Here, we propose a novel multimodal method combining independent components from MRI measures and clinical assessments to distinguish Alzheimer's patients or mild cognitive impairment (MCI) subjects from healthy elderly controls. 70 AD subjects (mean age: 77.15 +/- 6.2 years), 98 MCI subjects (mean age: 76.91 +/- 5.7 years), and 150 HC subjects (mean age: 75.69 +/- 3.8 years) were analyzed. Our method includes the following steps: pre-processing, estimating the number of independent components from the MR image data, extracting effective voxels for classification, and classification using a support vector machine (SVM)-based classifier. As a result, with regards to classifying AD from healthy controls, we achieved a classification accuracy of 97.7%, sensitivity of 99.2%, and specificity of 96.7%; for differentiating MCI from healthy controls, we achieved a classification accuracy of 87.8%, a sensitivity of 86.0%, and a specificity of 89.6; these results are better than those obtained with clinical measurements alone (accuracy of 79.5%, sensitivity of 74.0%, and specificity of 85.1%). We found that (1) both AD patients and MCI subjects showed brain tissue loss, but the volumes of gray matter loss in MCI subjects was far less, supporting the notion that MCI is a prodromal stage of AD; and (2) combining gray matter features from MRI and three commonly used measures of mental status, cognitive function improved classification accuracy, sensitivity, and specificity compared with classification using only independent components or clinical measurements. PMID- 29445430 TI - Seizure Prophylaxis in the Immediate Post-Hemorrhagic Period in Patients with Aneurysmal Subarachnoid Hemorrhage. AB - Introduction: Seizures are a well-known complication of aneurysmal subarachnoid hemorrhage (aSAH) and occur most commonly in the immediate posthemorrhagic period. Most commonly used antiepileptic drugs (AEDs) for seizure prophylaxis in aSAH include phenytoin and levetiracetam. There is no reliable data available on the safety and efficacy of restricting AED prophylaxis only till the aneurysm is secured. Methods: We retrospectively chart reviewed patients admitted to our neurosciences intensive care unit (NICU) with aSAH during the past two years. Seizure incidence was studied in patients treated with phenytoin versus levetiracetam and in patients treated for 3-7 days vs. those where AED was discontinued immediately after aneurysm was secured. Results: In 28 patients, AED prophylaxis was discontinued immediately after the aneurysm was secured, and in 21 patients, it was continued for 3-7 days. Of the 28 patients who received AED prophylaxis for less than or equal to two days, phenytoin was used in 20 patients and levetiracetam was used in eight patients. In patients receiving AED prophylaxis for 3-7 days, phenytoin was used in eight cases and levetiracetam was used in 13 cases. None of these patients had seizures reported during hospitalization or at three-month follow-up. Conclusion: Stopping the AED prophylaxis immediately after aneurysm coiling is not associated with increased risk of seizures. Seizures at presentation in patients with aSAH are not associated with development of epilepsy at three months. Both phenytoin and levetiracetam are well tolerated in patients with aSAH when limited to the immediate posthemorrhagic period. PMID- 29445431 TI - Outcome, Recurrence and Mortality after Non-Valvular Atrial Fibrillation Stroke: Long-Term Follow-Up Study. AB - Objective: Non-valvular atrial fibrillation (NVAF) is a major risk factor for ischemic stroke (IS) and a powerful predictor of mortality. This study investigates early and long-term outcome among patients with IS secondary to NVAF and identify the main factors associated with poor outcome, recurrence, and death. Methods: We analyzed the data from our consecutive NVAF acute IS database, over a period of 23 years. The endpoints were bad outcome (Modified Rankin Score >=3), recurrence, and mortality at discharge, after 6 months, 12 months, and final follow-up. Multivariate Cox and Kaplan-Meier analysis were used to estimate the probability of death. Results: 129 consecutive acute IS patients were included (77 [59.7%] females, mean age 70.2 +/- 10.1 years). Discharge, 6 and 12 months bad outcome was 62%, 63%, and 61%, respectively. After a median follow-up of 17 months (IQR 6-54.5), 35.6% patients had bad outcome, 21.7% had recurrence and 36.4% died. The recurrence and death annual rates were 19.1% and 6.32%. The absence of oral anticoagulation (OAC) and NIHSS score > 12 were the strongest predictors of mortality. Conclusions: IS secondary to NVAF has a high rate of stroke recurrence and mortality in our population, with the absence of OAC and major stroke as the main risk factors. PMID- 29445432 TI - Recurrent Intracerebral Hemorrhage after Exercise in a Young Patient Presenting with Sporadic Cerebral Amyloid Angiopathy in a Young Patient. AB - Cerebral Amyloid Angiopathy (CAA) is one of the significant causes of lobar intracerebral hemorrhage (ICH) mainly among elderly people. Sporadic cases of CAA have been linked to genetic polymorphisms with an increased risk of disease, an earlier presentation, and an accelerated pathology [1]. Here, we present a patient with no significant risk factors who had a recurrent intracerebral hemorrhage secondary to CAA probably induced by exercise. PMID- 29445433 TI - Upright Catheter-Based Cerebral Angiography. AB - Background: Several studies using Doppler ultrasound have suggested cerebral venous drainage is through paravertebral venous plexus due to the collapse of internal jugular veins in an upright position. Methods: We present a technique of acquiring venographic images during an upright position as part of catheter-based angiography to provide additional information regarding cerebral venous diseases. Angiographic images in anteroposterior projection were acquired in lying position and after patients were placed at 60 degrees using radiolucent supporting wedges on angiographic table. Results: In the first patient, there was activation of the paravertebral venous plexus as supplemental venous drainage to right internal jugular vein and stenosis of left internal jugular vein in high cervical segment in the upright position. There was relative collapse of both internal jugular veins in the mid-cervical region. In the second patient, there was attenuation of contrast opacification of right posterior cervical veins and complete occlusion of right internal jugular vein proximal extracranial segment (high-grade stenosis in lying position). There was activation of additional supplemental drainage to left internal jugular vein including paravertebral venous plexus. In the third patient, there was exacerbation of stenoses of the left and right internal jugular veins proximal extracranial segment in the upright position (moderate stenoses in lying position). There was activation of additional supplemental drainage via paravertebral venous plexus to both internal jugular veins. Conclusion: Our results demonstrate prominent changes in venous drainage patterns during upright angiographic images. Further studies would have to identify the patients in whom additional information in the upright angiography may provide clinically relevant information. PMID- 29445434 TI - Primary Endovascular Treatment of Acute Ischemic Stroke Using Stent Retrievers: Initial Egyptian Experience. AB - Background: Several mechanical thrombectomy (MT) devices have been designed with the goal of improving the recanalization rates of major intracranial artery occlusions. Objective: In this single-center experience, we analyzed the acute ischemic stroke (AIS) treatment with Primary MT; safety and efficacy and clinical results in our patients with large vessel occlusion (LVO). Methods: During a five year period (from September 2011 to July 2016), out of 996 patients who presented to our center with a diagnosis of AIS, 113 (11.4%) patients (55 men and 58 women) underwent primary mechanical recanalization within three hours from onset of signs and symptoms for anterior and 12 hours for posterior circulation (with computer tomography angiography/perfusion ELVO). Successful recanalization (thrombolysis in cerebral infarction 2b-3), good outcome (modified Rankin scale score 0-2) and overall mortality rate, and symptomatic intracranial hemorrhage [sICH: parenchymal hematoma Type 1 or Type 2; National Institutes of Health Stroke Scale (NIHSS) score increment >=4 points] were prospectively assessed. Results: The mean age of the patients was 62 +/- 11.73 years, with a baseline mean admission NIHSS score of 16.7 +/- 3.2. The mean time from onset to puncture (time to treatment) was 208.55 +/- 53.49. Successful recanalization was achieved in 104 (92%) cases. Good outcome was observed in 89 (78.8%) patients, and mortality was 11.5% (n = 13). sICH occurred in five (4.4%) patients. Conclusion: MT, within the first 4.5 hours, as primary treatment of acute LVO stroke provides high rate of recanalization and favorable clinical outcomes with low procedural complications. PMID- 29445435 TI - Investigation of Gender Differences and Exclusive Criteria in a Diabetic Acute Ischemic Stroke Population Treated with Recombinant Tissue-Type Plasminogen Activator (rtPA). AB - Background: Many studies have reported that women who survive stroke have less favorable outcomes than men in the use of rtPA, while others reported worse outcomes in men than women. The gender difference in the exclusion criteria in a diabetic stroke population is not fully understood. This issue was investigated in this study. Method: In a diabetic stroke population from a stroke registry of data collected between January 2010 to June 30, 2016, the gender difference was determined using demographics and clinical factors. Comparison was determined using univariate analysis while multivariable model was used to adjust for the effect of confounding variables. Results: In a diabetic stroke population of 439 patients, more females were excluded than males (P < 0.0001, OR = 2.323). The male exclusion was associated with atrial fibrillation (P = 0.011, OR = 3.697), carotid artery stenosis (P = 0.023, OR = 5.001), and cholesterol reducer (P = 0.037, OR = 0.409). In the female diabetic stroke population, exclusion from rtPA therapy was associated with language disturbances (P = 0.039, OR = 0.372), history of previous stroke (P = 0.005, OR = 3.276), antihypertensive medication use (P = 0.013, OR = 0.163), and antidiabetic medication use (P = 0.031, OR = 0.324). Conclusion: In a stroke population, women have a worse outcome than men in an untreated acute ischemic stroke population, but when treated there is no significant difference, suggesting a better treatment outcome for women compared to men. In a diabetic stroke population, the clinical variables for the exclusion criteria for women and men are significantly different, even after adjustment for confounding variables.

AB - Objective: We report the first experience with a new dual lumen guide catheter with lumen A with curved tip designed for delivery of stent and angioplasty catheters and lumen B with side exit for coaxial placement of stiff 0.014 inch wire. Methods: We prospectively determined technical success, intended procedure (stent delivery at target lesion and a final residual stenosis <30%) completed without a need for a different catheter, and technical ease, intended procedure completed without >=3 unsuccessful attempts in patients with symptomatic vertebral artery origin stenosis. Vertebral artery origin was classified as type A if originated from ascending segment and type B if originated from an arch or horizontal segment of subclavian artery. Results: The mean age of the four treated patients was 66.2 years (range 64-68 years). The mean percentage of vertebral artery origin stenosis was 82.7% (range 60-92%). The origin of vertebral artery from subclavian artery was classified as type A and type B origins in two patients each. The dual lumen catheter was advanced over an exchange length of 0.035 inch glide wire in one patient and directly through transfemoral insertion in three patients. Technical success and technical ease was achieved in all four procedures. Post procedure residual stenosis was 6% (range 5-7%). The primary operator rated the performance of guide catheter as superior compared with another catheter used in such procedures. Conclusion: The present study demonstrates the feasibility of performing stent placement for vertebral artery origin stenosis by using a dual lumen catheter with superior performance.

PMID- 29445440 TI - Comparison of Clinical and Radiological Outcome of Carotid Angioplasty and Stenting after Direct Navigation Versus Exchange Methods: A Randomized Clinical Trial. AB - Background: The purpose of this study was to compare the frequency of microembolic brain infarcts after direct navigation method versus exchange method in carotid artery stenting and vertebral artery origin angioplasty. Methods and Material: This is a prospective study conducted at Shiraz University of Medical Sciences in southern Iran. Consecutive patients undergoing "carotid angioplasty and stenting" and "vertebral artery origin stenting" were randomly assigned into two groups with "direct navigation method" and "exchange method." Subsequently, postprocedural magnetic resonance imaging (MRI) including diffusion weighted imaging and apparent diffusion coefficient were obtained within the first 24 hours after completion of the procedure. Results: In total, 89 patients were recruited (67% male, mean age: 72 years). Cases comprised of 38 left internal carotid arteries (ICAs), 38 right ICAs, 6 left vertebral artery origin, and 7 right vertebral artery origin. Forty patients underwent exchange method, while 49 underwent direct navigation method. There was only one clinical stroke that occurred in "exchange method" group. Fifteen patients (37.5%) in exchange group and 23 patients (46.9%) in direct navigation group developed diffusion restricted lesions. In exchange group, 13 patients (32.5%) had at least one diffusion restricted lesion ipsilateral to the target vessel, and three patients (7.5%) had at least one diffusion restricted lesion contralateral to the target vessel. In direct navigation group, these measures were 19 (38.8%) and 9 (18.4%). However, no statistically significant intergroup differences were observed. The only significant difference was bilateral infarct percentile, which was more common in the direct navigation method (0.032). Conclusion: Diffusion restricted lesions were more common in the direct navigation method, both ipsilateral and contralateral to the target vessel, and in both carotid and vertebral artery study subgroups. However, differences were not statistically significant. PMID- 29445441 TI - Potential New Cysteine Sparing Mutation in the NOTCH3 Gene in a Patient with Nonfamilial CADASIL-like Disease. AB - Background: Several different mutations have been reported in patients with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). We present a unique case with transversion not involving cysteine on neurogenic locus notch homolog protein 3 gene. Case description: We present a case of 65-year-old woman with new ischemic stroke resulting in right hemiparesis. She has previously suffered minor strokes at age 56, 58, and 60 years and migraine headaches between age 10 and 50 years. Magnetic resonance imaging demonstrated multifocal chronic ischemic infarctions with encephalomalacia in the left posterior parietal, parieto-occipital regions and the pons. An analysis of the protein sequence of notch 3 gene did not demonstrate any alterations characteristics of CADASIL disease. There was a deoxyribonucleic acid variant with transversion of alanine with tyrosine and change of histidine with leucine on notch 3 gene. None of the family members had any clinical manifestations suggestive of CADASIL. Conclusion: We report the first report of deoxyribonucleic acid variation in notch 3 gene associated with clinical features of CADASIL without any familial component.

AB - Background: ATP-binding cassette transporter super-family including ABCC1 and MDR 1 were involved in multi-drug resistance (MDR) of renal cell carcinoma (RCC) patients. Several miRNAs were confirmed to promote the MDR and the survival of tumor cells. Methods: The RCC cell lines Caki-2 with vinblastine-resistant (Caki 2/VBL) or doxorubicin-resistant (Caki-2/DOX) were constructed, respectively. The expressions of miR-210-3p, ABCC1 and MDR-1 protein were determined by qRT-PCR and Western blot assays. The viability of RCC cells was assessed by MTT assay. The regulatory relationship between miR-210-3p and ABCC1 was analyzed by Dual Luciferase assay. The effect of miR-210-3p in vivo was investigated with a tumor xenograft model in mice. Results: MiR-210-3p expression was observed to significantly decrease in Caki-2/VBL and Caki-2/DOX cells. Meanwhile, ABCC1 and MDR-1 were significantly increased in Caki-2/VBL and Caki-2/DOX cells. ABCC1 was a novel target of miR-210-3p and negatively regulated by miR-210-3p. And miR-210 3p improved drug-sensitivity of RCC cells. Down-regulation of ABCC1 could reverse the effect of miR-210-3p knockdown on the drug-resistance and the level of MDR-1 in drug-sensitive RCC cells. Conclusion: We confirmed that down-regulation of miR 210-3p increased ABCC1 expression, thereby enhancing the MRP-1-mediated multidrug resistance of RCC cells.

AB - Background Administration of coronary reperfusion therapy to patients with an acute myocardial infarction (AMI) within the proper timeframe is essential in avoiding clinical complications and death. However, the extent of pre-hospital delay is unexplored in Vietnam. This report aims to describe the duration of pre hospital delay of Hanoi residents hospitalized with a first AMI at the Vietnam National Heart Institute . Methods A total of 103 Hanoi residents hospitalized at the largest tertiary care medical center in the city for first AMI, who have information on prehospital delay was included in this report. Results One third of the study sample was women and mean age was 66 years. The mean and median pre hospital delay duration were 14.9 hours and 4.8 hours, respectively. The proportion of patients who delayed <6 , 6-<12, and >= 12 hours were 45%, 13%, and 42%, respectively. Conclusions Our data shows that a prolonged pre-hospital delay is often observed in patients with a first AMI in Vietnam. In order to confirm these findings, a full-scale investigation of all Hanoi residents hospitalized with first AMI is needed. Increasing public awareness about AMI treatment is vital in encouraging patients to seek medical care timely after experiencing AMI symptoms such that received treatment is most effective. PMID- 29445445 TI - Fe-S Clusters Emerging as Targets of Therapeutic Drugs. AB - Fe-S centers exhibit strong electronic plasticity, which is of importance for insuring fine redox tuning of protein biological properties. In accordance, Fe-S clusters are also highly sensitive to oxidation and can be very easily altered in vivo by different drugs, either directly or indirectly due to catabolic by products, such as nitric oxide species (NOS) or reactive oxygen species (ROS). In case of metal ions, Fe-S cluster alteration might be the result of metal liganding to the coordinating sulfur atoms, as suggested for copper. Several drugs presented through this review are either capable of direct interaction with Fe-S clusters or of secondary Fe-S clusters alteration following ROS or NOS production. Reactions leading to Fe-S cluster disruption are also reported. Due to the recent interest and progress in Fe-S biology, it is very likely that an increasing number of drugs already used in clinics will emerge as molecules interfering with Fe-S centers in the near future. Targeting Fe-S centers could also become a promising strategy for drug development. PMID- 29445448 TI - Surgical placement of a wireless telemetry device for cardiovascular studies of bovine calves. AB - Background: Domestic cattle ( Bos taurus) are naturally susceptible to hypoxia induced pulmonary arterial hypertension; consequently, the bovine calf has been used with considerable success as an animal model of the analogous human condition. Studies to date, however, have relied on instantaneous measurements of pressure and cardiac output. Here, we describe the surgical technique for placement of a fully implantable wireless biotelemetry device in a bovine calf for measurement of pulmonary arterial and left ventricular pressures, right ventricular output, and electrocardiogram. Methods: Three, 2-month old bovine calves underwent left-sided thoracotomies. A transit-time flow probe was placed around the pulmonary artery and solid-state pressure catheters inserted into the pulmonary artery and left ventricle. Biopotential leads were secured to the epicardium. The implant body was secured subcutaneously, dorso-caudal to the incision. Results: The implant and sensors were successfully placed in two of the three calves. One calf died from ventricular fibrillation following left ventricular puncture prior to pressure sensor insertion. Anatomical discrepancies meant that either 4 th or 5 th rib was removed. The calves recovered quickly with minimal complications that included moderate dyspnea and subcutaneous edema. Conclusions: Left thoracotomy is a viable surgical approach for wireless biotelemetry studies of bovine calf cardiovascular function. The real-time, contemporaneous collection of cardiovascular pressures and output, permits pathophysiological studies in a naturally susceptible, large animal model of pulmonary arterial hypertension. PMID- 29445449 TI - Early language development in preterm children without neurological damage: a longitudinal study. AB - Children born at a very low gestational age, even those without neurosensory damages, are at risk of linguistic disorders. This longitudinal study aimed at analyzing communicative and language abilities in preterm children during their second year of life, through a standardized questionnaire, with particular attention to the communicative and language abilities that predict the first verbal skills. Our results showed that preterm children are slower than full terms in language acquisition particularly at earlier stages of development. The differences between the two groups of children was significant only at 16 and 18 months. Preterms use more simplistic linguistic categories for longer than full terms, with regards to lexicon composition and syntactic complexity. This different pattern could involve more qualitative, rather than quantitative, aspects of developmental processes that characterize language acquisition in preterms and full-term children. PMID- 29445450 TI - Prevention of influenza-related illness in young infants by maternal vaccination during pregnancy. AB - The influenza virus circulates yearly and causes global epidemics. Influenza infection affects all age groups and causes mild to severe illness, and young infants are at particular risk for serious disease. The most effective measure to prevent influenza disease is vaccination; however, no vaccine is licensed for use in infants younger than 6 months old. Thus, there is a crucial need for other preventive strategies in this high-risk age group. Influenza vaccination during pregnancy protects both the mothers and the young infants against influenza infection. Vaccination during pregnancy boosts the maternal antibodies and increases the transfer of immunoglobulin G from the mother to the fetus through the placenta, which confers protection against infection in infants too young to be vaccinated. Data from clinical trials and observational studies did not demonstrate adverse effects to the mother, the fetus, or the infant after maternal influenza vaccination. We present the current data on the effectiveness and safety of influenza vaccination during pregnancy in preventing disease in the young infant. PMID- 29445451 TI - Recent progress on the molecular pharmacology of propofol. AB - The precise mechanism by which propofol enhances GABAergic transmission remains unclear, but much progress has been made regarding the underlying structural and dynamic mechanisms. Furthermore, it is now clear that propofol has additional molecular targets, many of which are functionally influenced at concentrations achieved clinically. Focusing primarily on molecular targets, this brief review attempts to summarize some of this recent progress while pointing out knowledge gaps and controversies. It is not intended to be comprehensive but rather to stimulate further thought, discussion, and study on the mechanisms by which propofol produces its pleiotropic effects. PMID- 29445453 TI - The European Falsified Medicines Directive in Poland: background, implementation and potential recommendations for pharmacists. AB - By February 2019, the Polish pharmaceutical industry, community and hospital pharmacies, wholesalers and parallel traders must all comply with the EU-wide Falsified Medicines Directive (FMD) legislation (2011/62/EU), to ensure that no medicinal product is dispensed to a patient without proper tracking and authentication. Here we describe how Poland is complying with the new EU regulations, the actions that have been taken to incorporate the FMD into Polish Pharmaceutical Law and whether or not these actions are sufficient. We found that Poland is only partially compliant with the FMD and further actions need to be undertaken to fully meet the Delegated Act (DA) requirements. Moreover, there is lack of awareness in Poland about the prevalence of falsified medication and the time scale required for implementation of the DA. Based on our findings, we suggest that a public awareness campaign should be started to raise awareness of the increased number of falsified medicines in the legal supply chain and that drug authorisation systems are implemented by Polish pharmacies to support the FMD. PMID- 29445452 TI - Exploiting immune cell metabolic machinery for functional HIV cure and the prevention of inflammaging. AB - An emerging paradigm in immunology suggests that metabolic reprogramming and immune cell activation and functions are intricately linked. Viral infections, such as HIV infection, as well as cancer force immune cells to undergo major metabolic challenges. Cells must divert energy resources in order to mount an effective immune response. However, the fact that immune cells adopt specific metabolic programs to provide host defense against intracellular pathogens and how this metabolic shift impacts immune cell functions and the natural course of diseases have only recently been appreciated. A clearer insight into how these processes are inter-related will affect our understanding of several fundamental aspects of HIV persistence. Even in patients with long-term use of anti retroviral therapies, HIV infection persists and continues to cause chronic immune activation and inflammation, ongoing and cumulative damage to multiple organs systems, and a reduction in life expectancy. HIV-associated fundamental changes to the metabolic machinery of the immune system can promote a state of "inflammaging", a chronic, low-grade inflammation with specific immune changes that characterize aging, and can also contribute to the persistence of HIV in its reservoirs. In this commentary, we will bring into focus evolving concepts on how HIV modulates the metabolic machinery of immune cells in order to persist in reservoirs and how metabolic reprogramming facilitates a chronic state of inflammation that underlies the development of age-related comorbidities. We will discuss how immunometabolism is facilitating the changing paradigms in HIV cure research and outline the novel therapeutic opportunities for preventing inflammaging and premature development of age-related conditions in HIV + individuals. PMID- 29445455 TI - Postnatal care utilization and associated factors among women of reproductive age Group in Halaba Kulito Town, Southern Ethiopia. AB - Background: Despite postnatal care services significant role in improving maternal and new-born health, services are underutilized in most developing countries including Ethiopia. Hence, it is important to identify factors that facilitate or impede postnatal care services utilization. The aim of this study was to assess postnatal care services utilization and associated factors among reproductive age women who gave live birth in 2015 at Halaba kulito town, Southern Ethiopia. Methods: A community-based cross-sectional study was conducted on 401 reproductive age women who gave live birth a year prior to the survey. Data were collected by using structured questionnaire. Bivariate and multivariable logistic regression analysis were carried out to identify factors associated with postnatal care services utilization. A significant association was declared when p-value is less than 0.05. The strength of association was determined by calculating odds ratio at 95% confidence interval. Result: In this study, postnatal care services utilization by reproductive age women was 47.9%. Multivariable analysis revealed that government employed (AOR = 3.01, 95%CI = 1.36, 6.67), have three ANC visits (AOR = 4.29, 95% CI = 1.59, 11.55), have four ANC visits (AOR = 9.55, 95% CI = (3.46, 26.39), gave last birth at Health Centre (AOR = 10.76, 95% CI = 3.26, 35.57), gave last birth at Hospital (AOR = 13.15, 95% CI = (3.64, 47.50), didn't aware of at least one postpartum danger signs (AOR = 0.06, 95% CI = (0.01, 0.37), didn't know child care and had three ANC visits (AOR =0 .14, 95% CI (0.02, 0.8), and didn't know child care and had four or more ANC visits (AOR =0 .13, 95% CI (0.02, 0.79) were significantly associated with postnatal care services utilization. Conclusion: This study assessed PNC services utilization and associated factors among reproductive age women. The study results provided a basic understanding of factors that associated with PNC services utilization by reproductive age women. The findings of this study showed direct association between postnatal care utilization and maternal employment, awareness to postpartum danger signs, frequency of ANC and attending birth at health institution. Therefore, the results suggested context-specific evidence which might be taken into consideration when rethinking policies to increase PNC utilization. PMID- 29445454 TI - Rumen-protected methionine during the peripartal period in dairy cows and its effects on abundance of major species of ruminal bacteria. AB - Background: Extensive degradation of amino acids in the rumen via microbial deamination decreases the post-ruminal availability of dietary indispensable amino acids. Together with the normal decrease in voluntary dry matter intake (DMI) around parturition in dairy cows, microbial metabolism contributes to a markedly negative balance of indispensable amino acids, including methionine which may be the first-limiting for milk production. The main objective of the current study was to profile changes in major bacterial species with key functions in cellulose and hemicellulose digestion, xylan breakdown, proteolytic action, propionic acid production, lactate utilization and ruminal biohydrogenation in cows supplemented with rumen-protected Methionine (SM; Smartamine M, Adisseo NA, Alpharetta, GA, USA) from -23 through 30 d relative to parturition. Because ~90% of the methionine in SM bypasses the rumen, ~10% of the methionine is released into the rumen and can be utilized by microbes. Results: As expected, there was an increase in overall DMI after parturition (Day, P < 0.05) during which cows consumed on average 19.6 kg/d versus 13.9 kg/d in the prepartum period. The postpartum diet contained greater concentrations of lipid and highly-fermentable carbohydrate from corn grain, which likely explains the increases in the relative abundance of Anaerovibrio lipolytica, Megasphaera elsdenii, Prevotella bryantii, Selenomonas ruminantium, Streptococcus bovis, and Succinimonas amylolytica. Despite similar DMI prepartum, cows fed SM had greater (Treatment * Day, P < 0.05) abundance prepartum of Fibrobacter succinogenes, Succinimonas amylolytica, and Succinivibrio dextrinosolvens. However, the greater DMI in cows fed SM after parturition (19.6 kg/d versus 13.9 kg/d) was associated with lower abundance of Fibrobacter succinogenes (2.13 * 10-3 versus 2.25 * 10-4) and Selenomonas ruminantium (2.98 * 10-1 versus 4.10 * 10-1). A lower abundance (Day, P < 0.05) was detected on d 20 compared with d -10 for Fibrobacter succinogenes and Succinivibrio dextrinosolvens. The relative abundance of Butyrivibrio proteoclasticus and Eubacterium ruminantium was stable across treatment and time. Conclusions: In diets with proper balance of rumen-degradable protein and fermentable carbohydrate, the small fraction of Methionine released from the rumen-protected supplement did not seem to compromise growth of major bacterial species in the rumen. In fact, it had a positive effect on 3 major species prepartum when DMI was similar between groups. Because the actual requirements of Methionine (and Lysine, for example) by the cow during the transition period are unknown, it appears warranted to study the rumen microbiome as it relates to supply of rumen-protected amino acids.

PMID- 29445502 TI - Long-term recovery following critical illness in an Australian cohort. AB - Background: Almost all data on 5-year outcomes for critical care survivors come from North America and Europe. The aim of this study was to investigate long-term mortality, physical function, psychological outcomes and health-related quality of life in a mixed intensive care unit cohort in Australia. Methods: This longitudinal study evaluated 4- to 5-year outcomes. Physical function (six-minute walk test) and health-related quality of life (Short Form 36 Version 2) were compared to 1-year outcomes and population norms. New psychological data (Center for Epidemiological Studies-Depression, Impact of Events Scale) was collected at follow-up. Results: Of the 150 participants, 66 (44%) patients were deceased by follow-up. Fifty-six survivors were included with a mean (SD) age of 64 (14.2). Survivors' mean (SD) six-minute walk distance increased between 1 and 4 to 5 years (465.8 m (148.9) vs. 507.5 m (118.2)) (mean difference = - 24.5 m, CI - 58.3, 9.2, p = 0.15). Depressive symptoms were low: median (IQR) score of 7.0 (1.0-15.0). The mean level of post-traumatic stress symptoms was low-median (IQR) score of 1.0 (0-11.0)-with only 9 (16%) above the threshold for potentially disordered symptoms. Short-Form 36 Physical and Mental Component Scores did not change between 1 and 4 to 5 years (46.4 (7.9) vs. 46.7 (8.1) and 48.8 (13) vs. 48.8 (11.1)) and were within a standard deviation of normal. Conclusions: Outcomes of critical illness are not uniform across nations. Mortality was increased in this cohort; however, survivors achieved a high level of recovery for physical function and health-related quality of life with low psychological morbidity at follow-up. Trial registration: The trial was registered with the Australian New Zealand Clinical Trials Registry ACTRN12605000776606. PMID- 29445503 TI - Overview of occupational cancer in painters in Korea. AB - Comprehensive consideration is necessary for setting guidelines to evaluate evidence of occupational cancer in painters due to work-related exposure to carcinogens in paint (a phenomenon termed herein as "work-relatedness"). The aim of the present research is to perform a comprehensive review and to suggest criteria for the provision of compensation for occupational neoplasm among painters in Korea. In order to perform a comprehensive review, this study assessed and evaluated scientific reports of carcinogenicities from the International Agency for Research on Cancer (IARC) and the Industrial Injuries Advisory Council (IIAC), as well as reviewed the existing literature about occupational exposure among painters in Korea and the epidemiologic investigations of claimed cases of cancer among painters in Korea. The IARC declares that occupational exposures in commercial painting are classified as Group 1 carcinogens for lung cancer and bladder cancer among painters. The epidemiologic studies show consistent causal relationships between occupational exposure in painters and cancers such as lung cancer [meta relative risk: 1.34 (95% confidence intervals (CIs): 1.23-1.41)] and bladder cancer [meta relative risk: 1.24 (95% CIs: 1.16-1.33)]. In reviewing occupational cancer risks for commercial painters, the Industrial Injuries Advisory Council (IIAC) confirms occupational cancer risks for lung and bladder cancer among commercial painters. According to the IIAC, however, the elevated cancer risks reported in existing literature are not doubled in either lung or bladder cancer in commercial painters relative to the risks of these cancers in the general population. Based on our review of existing Korean articles on the topic, painters are exposed to potential carcinogens including polycyclic aromatic hydrocarbons (PAHs), benzene, hexavalent chrome, crystalized silica, asbestos, and other agents, and relative levels are estimated within commercial painting processes. However, the cancer risks of occupational exposure to Group 1 carcinogens for lung and bladder cancer in painters per se are not fully assessed in existing Korean articles. Total work duration, potential carcinogens in paint, mixed exposure to paints across various industries such as construction and shipbuilding, exposure periods, latent periods, and other factors should be considered on an individual basis in investigating the work-relatedness of certain types of cancer in commercial painters. PMID- 29445504 TI - The relationship between night work and breast cancer. AB - Background: Since the International Agency for Research on Cancer classified shift work that involves circadian disruption as "probably carcinogenic to humans," there has been growing concern on the relationship between night work and breast cancer. In Korea, about 10-15% of workers are engaged in night-shift work, and breast cancer is one of the most common cancers in women. The purpose of this study was to review epidemiologic evidence on the relationship between night work and breast cancer. Methods: We reviewed 21 original articles and 5 meta analyses on relationship between nightwork and breast cancer, and investigated the compensation criteria of Denmark. Results: The association between breast cancer and night work has been reported by numerous epidemiologic studies, including cohort studies, case-control studies, and meta-analysis. However, a dose-response relationship has not clearly emerged among workers exposed to less than 20 years of night work. Conclusion: Although there are some limitations to the epidemiological studies so far, further consideration of breast cancer cases in patients with high exposure to night work is needed to assess breast cancer as a work-related disease. PMID- 29445506 TI - Ulinastatin did not reduce mortality in elderly multiple organ failure patients: a retrospective observational study in a single center ICU. AB - Aim: Our aim was to evaluate the effect of ulinastatin on 28-day mortality in patients who developed multiple organ failure (MOF) related to their acute illness and were admitted to the intensive care unit (ICU). Methods: We carried out a retrospective observational study of MOF patients in a general ICU of a tertiary care hospital in Japan from January 2009 to December 2012. The primary outcome was 28-day all-cause mortality. Secondary outcomes were ventilator-free days, ICU-free days, and vasopressor-free days at day 28. We investigated the association between ulinastatin treatment and outcomes using multivariable regression analysis. Results: A total of 212 MOF patients were included, 79 (37%) of whom received ulinastatin. The median age was 70 years (interquartile range, 60-77) and median APACHE II score was 25 (interquartile range, 19-29). Overall 28 day mortality was 20%. There were no significant differences between the ulinastatin group and the control group in age, gender, or APACHE II score. The ulinastatin group had higher prevalence of sepsis (44% versus 22%, P = 0.001). Multivariable logistic regression analysis showed that ulinastatin was not associated with 28-day mortality (odds ratio = 1.22; 95% confidence interval, 0.54-2.79). Moreover, ulinastatin did not reduce the mortality in patients with sepsis (odds ratio = 1.92; 95% confidence interval, 0.52-7.13). However, ICU-free days and ventilator-free days was significantly fewer in the ulinastatin group than control group. Conclusions: In this retrospective observational study, ulinastatin was not associated with mortality in elderly patients with established MOF, although it might be related to patient's utility. PMID- 29445507 TI - Development of the Japanese version of the Cornell Assessment of Pediatric Delirium. AB - Aim: Delirium is a form of acute cerebral dysfunction and is associated with increased length of hospital stay, mortality, and health-care costs for adult patients in intensive care. However, in Japan, there are currently no reliable criteria or tools for diagnosing delirium in critically ill pediatric patients. The purpose of this study was to translate the Cornell Assessment of Pediatric Delirium (CAPD)-a screening tool for pediatric delirium-from English to Japanese for use in the diagnosis of delirium for pediatric patients in pediatric intensive care units. Methods: The back-translation method was used to ensure equivalence in the Japanese version of the CAPD and its accompanying developmental anchor points. The translation process was repeated by a multidisciplinary committee of medical researchers and clinicians. Results: The final back-translated version of the CAPD was submitted to the original author, who gave her approval. Conclusion: The Japanese CAPD was developed and its effectiveness tested using a standardized procedure. Further study is required to test the validity and reliability of the Japanese version of the CAPD. PMID- 29445508 TI - Development of the Japanese version of the Preschool Confusion Assessment Method for the ICU. AB - Aim: Delirium is associated with various negative clinical outcomes, such as decline in cognitive ability, increased length of hospital stay, and higher mortality. For these reasons, early diagnosis of delirium is critical. Unfortunately, there are no reliable diagnostic criteria or tool of delirium for infants and preschool-aged children in Japan. : The aim of the present study was to translate a new delirium assessment tool, the Preschool Confusion Assessment Method for the Intensive Care Unit (psCAM-ICU), for accurately diagnosing clinically ill infants and preschool-aged children, from English to Japanese. Methods: The translation was undertaken with the internationally established back translation method. The translation was repeated blindly and independently by eight medical researchers and clinicians from multiple disciplines. Any discrepancy evident from the translated works was discussed and resolved. Results: We report the successful development of the Japanese version of psCAM ICU. However, before its full application, this diagnostic tool requires further testing and study, most notably for its validation and reliability. Conclusion: A Japanese version of the psCAM-ICU was developed. PMID- 29445509 TI - A case of paraplegia that developed 6 years after thoracic endovascular aortic repair for blunt traumatic aortic injury. AB - Case: Thoracic endovascular aortic repair (TEVAR) is becoming the standard therapy for blunt thoracic aortic injury (BTAI). However, the long-term outcomes of TEVAR for BTAI remain unclear. A 36-year-old man was admitted to our emergency department with dyspnea. He had been involved in a serious traffic accident 6 years earlier, requiring TEVAR for BTAI. Outcome: Acute heart failure and pneumonia were diagnosed on this admission. His respiratory condition improved, but paraplegia developed 10 h after hospitalization. Magnetic resonance imaging showed an intraspinal longitudinal area of signal hyperintensity, and spinal cord infarction was diagnosed. Conclusion: Although the causal relationship between the TEVAR and spinal cord infarction remains unclear, paraplegia as a long-term complication after TEVAR does not appear to have been reported previously, and so represents a potentially important complication.

PMID- 29445511 TI - Management of group b streptococcus-positive pregnant women at maternity homes in JAPAN: a questionnaire survey of compliance among midwives. AB - Background: Per the 2014 Japanese Midwives Association (JMA) guidelines, midwives were allowed to manage the deliveries for group B streptococcus (GBS)-positive pregnant women in labour at maternity homes without the supervision of a medical doctor if they complied with the guidelines of the Japan Society of Obstetrics and Gynecology (JSOG), wherein midwives working for maternity homes are expected to cooperate with commissioned obstetricians and paediatricians in cooperative medical facilities. We examined the rate of compliance with these JMA and JSOG guidelines regarding the management of GBS-positive pregnant women among midwives at maternity homes in Japan. Methods: Between October and December 2015, an anonymous questionnaire was distributed to 337 maternity homes registered with the JMA by mail. The questionnaire obtained information regarding the timing of GBS screening, specimen collection, transfer of GBS-positive pregnant women from a maternity home to a hospital, administration of intrapartum antibiotic prophylaxis, and collaboration between midwives and commissioned obstetricians. Data were analysed using descriptive statistics. We used frequency distribution as the statistical test. Results: Responses were received from 246 (73.0%) maternity homes, of which complete responses from 204 maternity homes (valid response rate, 60.5%) were analysed. Of these 204 maternity homes, only 97 (47.5%) conducted a GBS screening test during 33-37 weeks of gestation as recommended by the JSOG guidelines. Although midwives alone managed GBS-positive pregnant women in labour at 135 maternity homes (66.2%), intrapartum antibiotic prophylaxis, as recommended by the JSOG guidelines, was conducted in only 111 (54.4%). Moreover, only 37.0% (50/135) and 82.2% (111/135) of maternity homes ensured that GBS-positive pregnant women in labour with an elapse of >=18 h after PROM and a body temperature of >=38.0 degrees C, respectively, were transferred to a hospital by ambulance. Only at 58.3% (119/204) of maternity homes did midwives discuss the management of labour for GBS-positive pregnant women with commissioned obstetricians. Conclusions: Some midwives working for maternity homes did not follow the JMA and JSOG guidelines of the management of GBS positive pregnant women. For improving compliance rates, midwives at maternity homes should discuss the management of GBS-positive pregnant women with commissioned doctors more carefully and concretely per the existing guidelines. PMID- 29445512 TI - Changes in tear volume and ocular symptoms of patients receiving oral anticancer drug S-1. AB - Background: Most eye disorders are not fatal but may deteriorate the quality of life of a patient. The eye disorder that is most frequently reported in the cancer chemotherapy is associated with the combination of tegafur/gimeracil/potassium oxonate (S-1). However, preventive methods or treatment methods for the eye disorder have not yet been established. This study aimed to determine changes in tear volume and subjective ocular symptoms during the treatment period in patients receiving S-1 monotherapy for early detection of adverse effects in the eye and establishment of its treatment methods. Methods: This study included eleven patients receiving S-1 monotherapy as a postoperative adjuvant chemotherapy for gastric cancer. Six subjective ocular symptoms including watering eyes were evaluated and changes in tear volume measured by the Schirmer's test in patients receiving S-1 during the treatment period. In the present study, the patients were divided into "no watering eyes" (patients not experienced watering eyes) group and "watering eyes" (patients experienced watering eyes even once) group. Results: Six out of eleven patients developed watering eyes after receiving S-1 monotherapy. Among these, the earliest onset occurred on the 2nd week after oral administration. Watering eyes and eye discharge were highly related in patients having a trouble in daily life due to the decreased QOL. Changes in tear volume in the "watering eyes" group significantly increased compared to the "no watering eyes" group during the treatment period, especially when the patients had no subjective symptom of the increased tear volume. Conclusions: It is essential to prevent eye disorders including watering eyes as an adverse effect of S-1 administration. The present study recommends that the tear volume should be periodically measured using Schirmer's test, and the patient should be interviewed regarding the subjective ocular symptoms for the early detection of watering eyes caused by S-1 administration. If the tear volume can not be measured periodically, medical staffs should pay attention to the patient with eye discharge. PMID- 29445513 TI - Evaluating different interrow distance between corn and soybean for optimum growth, production and nutritive value of intercropped forages. AB - Background: Maize fodder is being used as staple feed for livestock but it lacks protein and essential amino acids; lysine and tryptophan. Intercropping maize with leguminous soybean crop is promising technique under limited land resources of South Korea but it can only give considerable advantages when adequate distance is provided between corn and soybean rows. Main aim of present study was to find-out adequate distance between corn and soybean seeding rows for optimum growth, yield and nutritive value of intercropped forage. Methods: Different interrow distances between corn and soybean were evaluated under four treatments, viz. 1) Corn sole as positive control treatment 2) Zero cm between corn and soybean (control); 2) Five cm between corn and soybean; 3) 10 cm between corn and soybean, with three replicates under randomized block design. Results: Findings depicted that height and number of corn stalks and ears were similar (P > 0.05) among different treatments. Numerically average corn ear height was decreased at zero cm distance. Dry matter percentage in all components; corn stalk, corn ear and soybean was also found not different (P > 0.05) but dry matter yield in component of corn ear was lower (P < 0.05) at zero cm distance as compared to that of 5 and 10 cm interrow distances. In case of nutritive value, total digestible nutrient yield in intercropped corn was also found lower (P < 0.05) at zero cm distance than that of 5 and 10 cm interrow distances between corn and soybean seeding rows. Substantial decrease in dry matter yield of maize ear at zero cm distance might be attributed to factor of closed interrow spacing which made interplant competition more intensified for light interception, necessary for photosynthetic activity. Lower dry matter yield in ear also reduced total digestible nutrients in intercropped maize because it was determining factor in calculation of digestible nutrients. The optimum yield and nutritive value of forage at wider interrow distance i.e. 5 cm between corn and soybean might be due to adequate interseed distance. Conclusion: Conclusively, pattern of corn and soybean seeding in rows at 5 cm distance was found suitable which provided adequate interrow distance to maintain enough mutual cooperation and decreased competition between both species for optimum production performance and nutritive value of intercropped forage. PMID- 29445514 TI - Exploring computerised cognitive training as a therapeutic intervention for people with Huntington's disease (CogTrainHD): protocol for a randomised feasibility study. AB - Background: Cognitive impairments, especially deficits of executive function, have been well documented as a core and early feature in Huntington's disease (HD). Cognitive impairments represent considerable burden and can be devastating for people and families affected by HD. Computerised cognitive training interventions that focus on improving executive function present a possible non pharmacological treatment option. We propose to determine the feasibility, acceptability, and appropriate outcome measures for use in a randomised controlled feasibility study. Methods/design: Participants will be randomised into either a computerised cognitive training group or a control group. Those randomised to the training group will be asked to complete a cognitive training intervention based on the HappyNeuron Pro software tasks of executive function, for a minimum of 30 min, three times a week for the 12-week study duration. Participants in the control group will not receive computerised cognitive training but will receive a similar degree of social interaction via equivalent study and home visits. We will explore quantitative outcome measures, including measures of cognitive performance, motor function, questionnaires and semi structured interviews, as well as magnetic resonance imaging (MRI) measures in a subset of participants. Feasibility will be determined through assessment of recruitment, retention, adherence and acceptability of the intervention. Discussion: The results of this study will provide crucial guidance and information regarding the feasibility of conducting a randomised controlled study into computerised cognitive training in HD. This study is crucial for the development of larger definitive randomised controlled trials which are powered to determine efficacy and for the development of future cognitive training programmes for people affected by HD. Trial registration: The study is registered on clinicaltrials.gov and has the unique identifier NCT02990676. PMID- 29445515 TI - Telementoring with project ECHO: a pilot study in Europe. AB - The Extension of Community Healthcare Outcomes (ECHO) project is a novel educational intervention designed in New Mexico to transfer subspecialty knowledge about hepatitis C virus (HCV) to primary care providers, thereby increasing patient access to HCV care. The ECHO model has been shown to deliver educational benefits and to result in good treatment outcomes for HCV-infected individuals in the USA; however, this approach has not been assessed in a European setting. We sought to evaluate the feasibility, acceptability and implementation of the ECHO model in Ireland using a pilot study. We present a descriptive review of recruitment, participation, retention and cost of the intervention as well as a qualitative review of the views of participants on the barriers, benefits and acceptability of the ECHO model. In the original Project ECHO in New Mexico, geographical distance posed the greatest barrier to accessing HCV care. In Ireland, people who inject drugs (PWID) were identified by interviewees as the main group facing barriers to accessing specialist HCV care. State-employed doctors and nurses caring for large numbers of HCV-infected PWID in opiate substitution treatment centres and homeless hostels were successfully recruited to participate in the project. Self-employed general practitioners did not participate, due mainly to a lack of time and the absence of reimbursement for participation. Practitioners who participated in the pilot reported benefits to themselves and their patients and would like to continue to participate in similar multidisciplinary, multisite educational interventions in the future. PMID- 29445516 TI - Does this treatment work for me? The patient's role in assessing medical care. AB - Randomised clinical trials are designed to determine whether a particular treatment is appropriate to make a significant difference to the health of a defined population and to aid its approval for use. For an accurate, cheap and simple assessment to see if a treatment benefits an individual person, all that is needed is a pen, paper, simple pocket calculator and daily recording of a few variables. It requires the ability to read and write and to understand addition and division. Factorial design of experiments is used to show the impact of several variables and their interaction on the person's health status. An example of a 75-year-old man with an enlarged prostate is used here to illustrate this approach. This person was able to understand and reduce side effects, lower the costs of medication by 83% and improve measured health status by 28%. A multivariate model for this person was then created with about 450 person-days of data. PMID- 29445505 TI - The Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2016 (J-SSCG 2016). AB - Background and Purpose: The Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2016 (J-SSCG 2016), a Japanese-specific set of clinical practice guidelines for sepsis and septic shock created jointly by the Japanese Society of Intensive Care Medicine and the Japanese Association for Acute Medicine, was first released in February 2017 in Japanese. An English language version of these guidelines was created based on the contents of the original Japanese-language version. Methods: Members of the Japanese Society of Intensive Care Medicine and the Japanese Association for Acute Medicine were selected and organized into 19 committee members and 52 working group members. The guidelines were prepared in accordance with the Medical Information Network Distribution Service (Minds) creation procedures. The Academic Guidelines Promotion Team was organized to oversee and provide academic support to the respective activities allocated to each Guideline Creation Team. To improve quality assurance and workflow transparency, a mutual peer review system was established, and discussions within each team were open to the public. Public comments were collected once after the initial formulation of a clinical question (CQ), and twice during the review of the final draft. Recommendations were determined to have been adopted after obtaining support from a two-thirds (>66.6%) majority vote of each of the 19 committee members. Results: A total of 87 CQs were selected among 19 clinical areas, including pediatric topics and several other important areas not covered in the first edition of the Japanese guidelines (J-SSCG 2012). The approval rate obtained through committee voting, in addition to ratings of the strengths of the recommendation and its supporting evidence were also added to each recommendation statement. We conducted meta analyses for 29 CQs. Thirty seven CQs contained recommendations in the form of an expert consensus due to insufficient evidence. No recommendations were provided for 5 CQs. Conclusions: Based on the evidence gathered, we were able to formulate Japanese-specific clinical practice guidelines that are tailored to the Japanese context in a highly transparent manner. These guidelines can easily be used not only by specialists, but also by non-specialists, general clinicians, nurses, pharmacists, clinical engineers, and other healthcare professionals. PMID- 29445518 TI - Why do endocrine profiles in elite athletes differ between sports? AB - Background: Endocrine profiles have been measured on blood samples obtained immediately post-competition from 693 elite athletes from 15 Olympic Sports competing at National or International level; four were subsequently excluded leaving 689 for the current analysis. Methods: Body composition was measured by bioimpedance in a sub-set of 234 (146 men and 88 women) and from these data a regression model was constructed that enabled 'estimated' lean body mass and fat mass to be calculated on all athletes. One way ANOVA was used to assess the differences in body composition and endocrine profiles between the sports and binary logistical regression to ascertain the characteristic of a given sport compared to the others. Results: The results confirmed many suppositions such as basketball players being tall, weightlifters short and cross-country skiers light. The hormone profiles were more surprising with remarkably low testosterone and free T3 (tri-iodothyronine) in male powerlifters and high oestradiol, SHBG (sex hormone binding globulin) and prolactin in male track and field athletes. Low testosterone concentrations were seen 25.4% of male elite competitors in 12 of the 15 sports and high testosterone concentrations in 4.8% of female elite athletes in 3 of the 8 sports tested. Interpretation of the results is more difficult; some of the differences between sports are at least partially due to differences in age of the athletes but the apparent differences between sports remain significant after adjusting for age. The prevalence of 'hyperandrogenism' (as defined by the IAAF (International Association of Athletics Federations) and IOC (International Olympic Committee)) amongst this cohort of 231 elite female athletes was the highest so far recorded and the very high prevalence of 'hypoandrogenism' in elite male athletes a new finding. Conclusions: It is unclear whether the differences in hormone profiles between sports is a reason why they become elite athletes in that sport or is a consequence of the arduous processes involved. For components of body composition we know that most have a major genetic component and this may well be true for endocrine profiles. PMID- 29445517 TI - Autonomic components of Complex Regional Pain Syndrome (CRPS) are favourably affected by Electrical Twitch-Obtaining Intramuscular Stimulation (ETOIMS): effects on blood pressure and heart rate. AB - Introduction: Favourable pain relief results on evoking autonomous twitches at myofascial trigger points with Electrical Twitch Obtaining Intramuscular Stimulation (ETOIMS). Aim: To document autonomic nervous system (ANS) dysfunction in Complex Regional Pain Syndrome (CRPS) from blood pressure (BP) and pulse/heart rate changes with ETOIMS. Methods and materials: A patient with persistent pain regularly received serial ETOIMS sessions of 60, 90, 120 or >=150 min over 24 months. Outcome measures include BP: systolic, diastolic, pulse pressure and pulse/heart rate, pre-session/immediate-post-session summed differences (SDPPP index), and pain reduction. His results were compared with that of two other patients and one normal control. Each individual represented the following maximal elicitable twitch forces (TWF) graded 1-5: maximum TWF2: control subject; maximum TWF3: CRPS patient with suspected ANS dysfunction; and maximum TWF4 and TWF5: two patients with respective slow-fatigue and fast-fatigue twitches who during ETOIMS had autonomous twitching at local and remote myotomes simultaneously from denervation supersensitivity. ETOIMS results between TWFs were compared using one-way analysis of variance test. Results: The patients showed immediate significant pain reduction, BP and pulse/heart rate changes/reduction(s) except for diastolic BP in the TWF5 patient. TWF2 control subject had diastolic BP reduction with ETOIMS but not with rest. Linear regression showed TWF grade to be the most significant variable in pain reduction, more so than the number of treatments, session duration and treatment interval. TWF grade was the most important variable in significantly reducing outcome measures, especially pulse/heart rate. Unlike others, the TWF3 patient had distinctive reductions in SDPPP index. Conclusions: Measuring BP and pulse/heart rate is clinically practical for alerting ANS dysfunction maintained CRPS. SDPPP index (>=26) and pulse/heart rate (>=8) reductions with almost every ETOIMS treatment, plus inability to evoke autonomous twitches due to pain-induced muscle hypertonicity, are pathognomonic of this problem. PMID- 29445519 TI - Highly efficient generation of knock-in transgenic medaka by CRISPR/Cas9-mediated genome engineering. AB - Background: Medaka (Oryzias latipes) is a popular animal model used in vertebrate genetic analysis. Recently, an efficient (~ 30%) knock-in system via non homologous end joining (NHEJ) was established in zebrafish using the CRISPR/Cas9 system. If the same technique were applicable in medaka, it would greatly expand the usefulness of this model organism. The question of the applicability of CRISPR/Cas9 in medaka, however, has yet to be addressed. Results: We report the highly efficient generation of knock-in transgenic medaka via non-homologous end joining (NHEJ). Donor plasmid containing a heat-shock promoter and a reporter gene was co-injected with a short guide RNA (sgRNA) targeted for genome digestion, an sgRNA targeted for donor plasmid digestion, and Cas9 mRNA. Broad transgene expression in the expression domain of a target gene was observed in approximately 25% of injected embryos. By raising these animals, we established stable knock-in transgenic fish with several different constructs for five genetic loci, obtaining transgenic founders at efficiencies of > 50% for all five loci. Further, we show that the method is useful for obtaining mutant alleles. In the experiments where transgene integrations were targeted between the transcription start site and the initiation methionine, the resultant transgenic fish became mutant alleles. Conclusion: With its simplicity, design flexibility, and high efficiency, we propose that CRISPR/Cas9-mediated knock-in via NHEJ will become a standard method for the generation of transgenic and mutant medaka. PMID- 29445520 TI - Efficacy and safety of azilsartan medoxomil, an angiotensin receptor blocker, in Korean patients with essential hypertension. AB - Background: This was a phase 3, randomized, double-blind, placebo-controlled study. Methods: Adult Korean patients with essential hypertension and a baseline mean sitting clinic systolic blood pressure (scSBP) >=150 and <=180 mmHg were randomized to 6-week treatment with placebo (n = 65), azilsartan medoxomil (AZL M) 40 mg (n = 132), or AZL-M 80 mg (n = 131). The primary endpoint was the change from baseline to week 6 in trough scSBP. Results: The least-squares mean (standard error) change from baseline in trough scSBP in the placebo, AZL-M 40 mg, and 80-mg groups at week 6 were - 8.8 (2.00), - 22.1 (1.41), and - 23.7 (1.40) mmHg, respectively (p < 0.001 for AZL-M 40 and 80 mg vs placebo). No clinically meaningful heterogeneity in efficacy was observed between subgroups (age, sex, diabetes status) and the overall population. Treatments were well tolerated and adverse events were similar between groups. Conclusions: Results of this study confirm a positive benefit-risk profile of AZL-M for essential hypertension in Korean adults. Trial registration: Clinicaltrial.gov; identifier number: NCT02203916.

AB - Plain English summary: The purpose of this paper is to describe a patient engagement event designed to create an educational workbook with smokers who drink alcohol at harmful levels. The goal was to create a workbook that combined scientific evidence with patients' values, preferences, and needs. Fourteen adult smokers who drink alcohol were invited to the Centre for Addiction and Mental Health (CAMH) to take part in a four-hour event to help design the workbook with the CAMH research team. Participants provided their opinions and ideas to create an outline for the workbook, including activities, images, and titles. The workbook - called Self-Awareness - is currently being offered in a smoking cessation program in 221 primary care clinics across Ontario to help smokers quit or reduce their harmful alcohol use. The patient engagement event was a useful way to co-create educational materials that incorporate both scientific research and patient needs. Abstract: Background Evidence-based medicine is the integration of best research evidence with clinical expertise and patient values. There are few methodologies on how to design evidence-based programs and resources to include patient values. The latter is an important aspect of patient centered care, and is essential for patients to trust the recommendations and empower them as consumers to make informed choices. This manuscript describes a participatory research approach to design patient-facing educational materials that incorporate both evidence-based and community-sensitive principles. These materials are intended to support smokers to reduce or stop harmful alcohol consumption. Methods Adult smokers who report consuming alcohol were invited to a co-creation meeting at the Centre for Addiction and Mental Health's Nicotine Dependence Service to guide the adaptation of evidence-based materials. The four hour event consisted of individual reflections, group discussions, and consensus building interactions. Detailed notes were taken and then incorporated into the material. Results Fourteen individuals participated in the event. The end product was a descriptive outline of an educational resource - entitled Self-Awareness - incorporating material from evidence-based workbooks and patient-driven features. Participants collaboratively selected the resource's content, structure, and titles. Conclusions This model describes a participatory research method that emphasizes the value of the patient perspective; preliminary evidence finds this adaptation approach can increase the adoption of resources. The process described in this article could be replicated in other settings to co-create evidence-based resources, interventions, and programs that reflect the needs of the community.

AB - Background: Evaluation of the impact of different macular optical coherence parameters on visual acuity as early as 1 day after injection of ranibizumab in patients with subfoveal exsudative age-related macular degeneration. Methods: This was an interventional, non randomized, open label prospective study, where we evaluated 20 eyes of 20 patients affected by exudative age-related macular degeneration. These patients were treated with injections of ranibizumab between February 2013 and January 2015. The primary endpoint of this study was to evaluate the early changes in optical coherence tomography parameters (retinal thickness, central and total retinal volume) and impact on best-corrected visual acuity (BCVA) obtained by logarithm of minimum resolution using ETDRS protocol in patients treated with a single dose intravitreal injection of ranibizumab (0.5 mg/0.05 mL) during the first month of follow. The patients were evaluated on the first day, them at 7 and 30 days after the treatment. The National Eye Institute Visual Functioning Questionnaire was applied during the study period to assess early perception of ranibizumab injection effectiveness. The adverse events were monitored throughout the study. Results: Central retinal thickness values at 1 (464.0 +/- 97.8 um), 7 (379.9 +/- 107.8 um) and 30 days (365.5 +/- 95.1 um) after ranibizumab injection showed a statically significant reduction when compared with baseline results (P = 0.01, P = 0.001, P = 0.001, respectively). Similar alterations were observed in central and total retinal volume, which were detected early on the first day of evaluation, after the measurement at baseline (central: 0.36 +/- 0.07 vs. 0.40 +/- 0.10 mm3, P = 0.01; total: 9.62 +/- 1.10 vs. 9.99 +/- 2.56 mm3, P = 0.002) and remained steady at 7 (P = 0.001, P = 0.002, respectively) and 30 days (P = 0.001, P = 0.004, respectively) with slight variations without losing their gains in these parameters. The best-corrected logarithm of minimum angle of resolution (logMAR) showed a statistically significant difference when compared to the baseline. (0.81 +/- 0.16 vs. 0.67 +/- 0.24, P = 0.005). The NEI-VFQ-25 questionnaire demonstrate statically significant results after treatment. When patients were asked about the subjective improvement in visual quality, over 80% reported early improvement. Throughout the period of follow-up visits, no serious adverse events were reported. Conclusion: Intravitreal injection of ranibizumab can produce early changes in optical coherence tomography parameters and an improvement in perceived visual quality of patients with subfoveal exsudative age-related macular degeneration.

PMID- 29445525 TI - Physiological consequences of CPAP therapy withdrawal in patients with obstructive sleep apnoea-an opportunity for an efficient experimental model. AB - Randomised controlled trials (RCTs) of continuous positive airway pressure (CPAP) in obstructive sleep apnoea (OSA) are time consuming, and their findings often inconclusive or limited due to suboptimal CPAP adherence in CPAP-naive patients with OSA. Short-term CPAP withdrawal in patients with prior optimal CPAP adherence results in recurrence of OSA and its consequences. Thus, this experimental model serves as an efficient tool to investigate both the consequences of untreated OSA, and potential treatment alternatives to CPAP. The CPAP withdrawal protocol has been thoroughly validated, and applied in several RCTs focusing on cardiovascular and metabolic consequences of untreated OSA, as well as the assessment of treatment alternatives to CPAP.

PMID- 29445526 TI - Intermittent hypoxia, cardiovascular disease and obstructive sleep apnoea. AB - Obstructive sleep apnoea (OSA) is a common disorder and is associated with cardiovascular disease. Continuous positive airway pressure (CPAP), whilst reducing blood pressure, has not been shown to reduce cardiovascular events when used as a treatment solely for this purpose in patients with previous cardiovascular disease. Developing a better understanding of the mechanisms underlying cardiovascular disease in OSA is important to develop new treatments. Potential causative mechanisms for cardiovascular disease in OSA include arousal induced sympathetic activation, large intrathoracic pressure swings leading to shear stress on the heart and great vessels, and intermittent hypoxia (IH). This review discusses the role of IH, as a major physiological consequence of OSA, in the development of cardiovascular disease. PMID- 29445527 TI - Drug induced sleep endoscopy: its role in evaluation of the upper airway obstruction and patient selection for surgical and non-surgical treatment. AB - Sleep related breathing disorders cause obstruction of the upper airway which can be alleviated by continuous positive airway pressure (CPAP) therapy, oral devices or surgical intervention. Non-surgical treatment modalities are not always accepted by patients and in order to attain successful surgical outcomes, evaluation of the upper airway is necessary to carefully select the patients who would benefit from surgery. There are numerous techniques available to assess the upper airway obstruction and these include imaging, acoustic analysis, pressure transducer recording and endoscopic evaluation. It is essential to note that the nocturnal obstructive upper airway has limited muscle control compared to the tone of the upper airway lumen during wakefulness. Thus, if one were to attempt to identify the anatomical segments contributing to upper airway obstruction in sleep related breathing disorders; it must be borne in mind that evaluation of the airway must be performed if possible when the patient is awake and asleep albeit during drug induced sleep. This fact as such limits the use of imaging techniques for the purpose. Drug induced sleep endoscopy (DISE) was pioneered at Royal National Throat, Nose and Ear Hospital, London in 1990 and initially introduced as sleep nasendoscopy. The nomenclature and the technique has been modified by various Institutions but the core value of this evaluation technique remains similar and extremely useful for identifying the anatomical segment responsible for obstructing the upper airway during sleep in patients with sleep related breathing disorders. There have been numerous controversies that have surrounded this technique but over the last two decades most of these have been addressed and it now remains in the forefront of methods of evaluating the upper airway obstruction. A variety of sedative agents and different grading systems have been described and efforts to unify various aspects of the technique have been made. This article will look at its usefulness and advantages and will discuss some important contributions made to the field of evaluation of the upper airway using DISE. PMID- 29445528 TI - An update on mandibular advancement devices for the treatment of obstructive sleep apnoea hypopnoea syndrome. AB - Continuous positive airway pressure (CPAP) remains the gold standard treatment for obstructive sleep apnoea hypopnoea syndrome (OSAHS). However, the high efficacy of CPAP is offset by intolerance and poor compliance, which can undermine effectiveness. This means that alternatives to CPAP are also necessary. In recent years, oral appliances have emerged as the leading alternative to CPAP. There is now a strong body of evidence supporting their use in OSAHS and clinical guidelines now recommend their use in mild OSAHS and in more severe cases when CPAP fails. These devices are by no means a homogenous group as they differ greatly in both design and action. The most commonly used appliances are mandibular advancement devices (MAD) that increase airway diameter with soft tissue displacement achieved by mandibular protrusion. Despite the growing evidence, there are still barriers to MAD provision. Their effectiveness can be difficult to predict and there is debate about the required level of design sophistication. These uncertainties prevent more widespread inclusion of MAD within clinical sleep services. This review will focus on the efficacy, effectiveness, design features, side-effects of and patient selection for MAD therapy. Comparison will also be made between MAD and CPAP therapy. PMID- 29445529 TI - Cardiorespiratory interaction with continuous positive airway pressure. AB - The treatment of choice for obstructive sleep apnoea (OSA) is continuous positive airway pressure therapy (CPAP). Since its introduction in clinical practice, CPAP has been used in various clinical conditions with variable and heterogeneous outcomes. In addition to the well-known effects on the upper airway CPAP impacts on intrathoracic pressures, haemodynamics and blood pressure (BP) control. However, short- and long-term effects of CPAP therapy depend on multiple variables which include symptoms, underlying condition, pressure used, treatment acceptance, compliance and usage. CPAP can alter long-term cardiovascular risk in patients with cardiorespiratory conditions. Furthermore, the effect of CPAP on the awake patient differs from the effect on the patients while asleep, and this might contribute to discomfort and removal of the use interface. The purpose of this review is to highlight the physiological impact of CPAP on the cardiorespiratory system, including short-term benefits and long-term outcomes. PMID- 29445531 TI - Patient ventilator asynchrony and sleep disruption during non-invasive ventilation. AB - Patient-ventilator asynchrony (PVA) are a common phenomenon affecting all patients receiving long-term domiciliary ventilation. The interruption of synchrony between the patient and the ventilator has been reported to be a possible cause of nocturnal sleep disruption leaking to arousals, awakenings and reduced periods of stage 3 and REM sleep overnight. The cause of PVA is multi factorial driven frequently by leak at the interface, changing respiratory breathing patterns and changes in sleep stages. It currently remains unclear as to whether the PVA is the cause of sleep fragmentation or if PVA is purely a marker of unsuccessful ventilatory control, patient discomfort and underlying sleep disruption. PMID- 29445530 TI - Update: non-invasive ventilation in chronic obstructive pulmonary disease. AB - Chronic obstructive pulmonary disease (COPD) remains a common cause of morbidity and mortality worldwide. Patients with COPD and respiratory failure, whether acute or chronic have a poorer prognosis than patients without respiratory failure. Non-invasive ventilation (NIV) has been shown to be a useful tool in both the acute hospital and chronic home care setting. NIV has been well established as the gold standard therapy for acute decompensated respiratory failure complicating an acute exacerbation of COPD with reduced mortality and intubation rates compared to standard therapy. However, NIV has been increasingly used in other clinical situations such as for weaning from invasive ventilation and to palliate symptoms in patients not suitable for invasive ventilation. The equivocal evidence for the use of NIV in chronic hypercapnic respiratory failure complicating COPD has recently been challenged with data now supporting a role for therapy in selected subgroups of patients. Finally the review will discuss the emerging role of high flow humidified therapy to support or replace NIV in certain clinical situation. PMID- 29445532 TI - Sleep disordered breathing in motor neurone disease. AB - Motor neurone disease (MND) is a neurodegenerative disease defined by axonal loss and gliosis of upper and lower motor neurones in the motor cortex, lower brainstem nuclei and ventral horn of the spinal cord. MND is currently incurable and has a poor prognosis, with death typically occurring 3 to 5 years after disease onset. The disease is characterised by rapidly progressive weakness leading to paralysis, fasciculations, bulbar symptoms (including dysarthria and dysphagia) and respiratory compromise. Respiratory complications arise as a result of weakness of upper airway (pharyngeal and laryngeal) muscles and respiratory muscles (diaphragm, intercostal and accessory muscles) leading to respiratory failure. Due to early involvement of respiratory muscles in MND, sleep disordered breathing (SDB) occurs at a higher frequency than compared to the general population. SDB usually precedes daytime respiratory symptoms and chronic respiratory failure. It significantly impacts upon patients' quality of life and survival and its presence may predict prognosis. Managing SDB in MND with non-invasive ventilation (NIV) improves quality of life and survival. Early identification and management of SDB in MND patients is therefore crucial. This update will review assessments of respiratory muscle function, types of SDB and the effects of NIV in patients with MND. PMID- 29445533 TI - Insomnia and cognitive behavioural therapy-how to assess your patient and why it should be a standard part of care. AB - Hippocrates recognized the importance of asking about sleep as long ago as 400 BC when he wrote "sleep and watchfulness, both of them when immoderate, constitute disease". Disrupted sleep for any reason has immediate and long term consequences on physical and mental health. Insomnia disorder ("immoderate watchfulness") remains the commonest sleep disorder in primary and secondary care with an estimated 5-10% of the adult population affected. While it is commonly comorbid with other physical and mental health problems, the new diagnostic classification has been helpfully simplified such that it is considered a disorder in itself. If it is the patient's main concern, it warrants treatment. Patients and health professionals have often had limited teaching about effective strategies for insomnia which leaves many untreated and insomnia can be unfairly perceived as a challenging symptom to manage. The first line treatment is now well established as insomnia-specific cognitive behavioural therapy (CBTi) in the most recent US and European treatment guidelines. Over 25 years of high quality research have shown evidence for sustained improvements in sleep in those with insomnia alone or insomnia comorbid with other conditions. This is a simple CBT to deliver with better and safer outcomes than prescription hypnotics. Therefore, this review will cover the initial assessment of insomnia, including insomnia mimics, the selection of patients for treatment and the key components of CBT therapy. Finally, the review will cover evidence for different modes of delivery (online, self, help, group or individual face to face) in a variety of clinical settings. PMID- 29445534 TI - Delayed sleep-wake phase disorder. AB - Delayed sleep-wake phase disorder (DSWPD) is the most commonly encountered of the circadian rhythm sleep-wake disorders (CRSDs), and is often confused with sleep initiation insomnia. It typically emerges in teenage years and persists into adulthood. In essence, people with the disorder have an abnormally delayed major sleep episode relative to the dark phase of the solar cycle, and hence great difficulty initiating sleep at an appropriately early time, and, as a knock-on effect, waking at a desirable time in the morning, leading to chronic, and often quite severe sleep restriction trying to conform to a 9 to 5 schedule. As a result, sleep on free days is often extended in compensation. When released from such schedule constraints, sleep duration and quality is normal; it is just delayed. This review highlights elements of our current understanding of the epidemiology, associations and pathophysiology of the disorder, before discussing how some of our knowledge of sleep and circadian physiology can be applied to guide treatment of it. PMID- 29445535 TI - Clinical update on central hypersomnias. AB - The central hypersomnias encompass a range of conditions causing persisting or intermittent excessive daytime sleepiness (EDS). These conditions therefore present not infrequently in general clinical sleep practice, and remain in the differential for patients presenting with sleepiness. Our understanding of the pathophysiology, diagnosis and management of these conditions has progressed significantly over recent years, and in this article we review this group of disorders, focussing in particular on recent changes in classification and diagnosis, pathophysiological advances, and novel treatment options. PMID- 29445536 TI - Predictors of long-term adherence to continuous positive airway pressure in patients with obstructive sleep apnoea and acute coronary syndrome. AB - Background: Continuous positive airway pressure (CPAP) is an effective treatment for obstructive sleep apnoea (OSA), but an evaluation of CPAP adherence is rarely carried out among patients with acute coronary syndrome (ACS). The goals of the study are to analyse long-term adherence and identify the predictors of non compliance with CPAP treatment for patients with non-sleepy OSA and ACS. Methods: This is an ancillary study of the ISAACC study, which is a multicentre, prospective, open-label, parallel, randomized, and controlled trial (NCT01335087) in patients with hospital admission for ACS. For the purpose of this study, only non-sleepy patients with moderate or severe OSA and randomized to receive CPAP treatment were analysed (n=357). Non-compliance was defined as CPAP dropout or average cumulative CPAP use of <4 hours/night. Multivariable logistic regression analysis was performed to identify predictors of CPAP adherence. Results: Adherence to treatment was 35.3% at 12 months. According to the unadjusted analysis, higher apnoea-hypopnea index (AHI) (P<0.001) and oxygen desaturation index (ODI) (P=0.001) were associated with a lower risk of non-compliance. Multivariable logistic regression analysis showed that high AHI (P=0.0051), high amounts of smoking pack-year (P=0.0170), and long intensive care unit (ICU) stays (P=0.0263) were associated with lower odds of non-compliance. It also showed a significant interaction between ACS history and age (P=0.0131), such that young patients with their first ACS showed significantly lower odds of CPAP non compliance than patients with recurrent ACS and significantly lower odds of CPAP non-compliance were associated with ageing only in patients with recurrent ACS. Conclusions: Protective factors against non-compliance with CPAP treatment in non sleepy patients with ACS were illness severity (high values of AHI or ICU stay length) or smoking amount. Patients with no previous history of ACS showed lower odds of CPAP non-compliance than patients with a recurrent ACS with younger age. PMID- 29445537 TI - Neural respiratory drive and cardiac function in patients with obesity hypoventilation syndrome following initiation of non-invasive ventilation. AB - Background: Chronic hypercapnic respiratory failure (HRF) in obesity hypoventilation syndrome (OHS) is commonly treated using non-invasive ventilation (NIV). We hypothesised that treatment of OHS would improve neural respiratory drive index (NRDI) and cardiac function. Methods: Fourteen patients (8 females) with OHS, who were admitted for initiation of domiciliary NIV, were prospectively studied. Patients had (mean +/- SD): age (53+/-10 years), body mass index (BMI) (50.1+/-10.8 kg/m2), and pCO2 (7.3+/-0.9 kPa). NRDI was assessed by surface electromyogram of the parasternal intercostals. Cardiac function was assessed by transthoracic echocardiography (TTE). All measurements were performed at baseline, 6 weeks, and 3 months. Results: NRDI improved on day one following NIV set-up comparing to baseline (484.2+/-214.8 vs. 316.5+/-106.5 AU) and this improvement was maintained at 6 weeks (369.1+/-173.2 AU) and at 3 months (351.2+/ 167.1 AU) (P=0.004). No significant differences were identified in terms of cardiac function between baseline and 3 months [tricuspid annular plane systolic excursion (TAPSE) (24.6+/-5.8 vs. 23.0+/-4.0 mm, P=0.317); systolic pulmonary artery (PA) pressures (36.7+/-15.2 vs. 44.5+/-23.9 mmHg, P=0.163]. Conclusions: NIV improves NRDI in patients with OHS, while the cardiac function over a three month period remains unchanged. PMID- 29445538 TI - Peri-operative treatment of sleep-disordered breathing and outcomes in bariatric patients. AB - Background: Obstructive sleep apnoea (OSA) is increasingly common in bariatric patients undergoing sedation during elective surgery. However, it has not been established how significant a contributor it is to peri-operative respiratory complications and mortality. We sought to pre-operatively identify OSA in bariatric patients and record peri-operative complications during and after bariatric surgery. Methods: Data were collected and analysed from June 2014 to March 2017 for 410 bariatric surgery patients referred to the sleep laboratory for pre-operative screening and treatment of OSA. The STOP-Bang questionnaire, Epworth Sleepiness Scale (ESS) and nocturnal pulse oximetry were recorded and treatment was allocated with continuous positive airway pressure (CPAP). Peri operative complications and mortality were the primary outcome measures for patients receiving CPAP treatment for OSA, with patients who did not require CPAP used as control. The mean follow-up time for all patients was 433 and 732 days for the patients who had undergone bariatric surgery. The two groups were compared with Chi square test and unpaired two-tailed t-test. Results: OSA was present in any form in 70% of the screened patients; 40% of patients involved in the study received CPAP treatment. Patients receiving CPAP treatment [49.5 (11.3) years old, 61% female, 50.3 (8.5) kg/m2] were older, had a lower percentage of females and had a higher body mass index (BMI) than those not receiving CPAP [44.9 (12.0), 81% female, 46.6 (7.7)]. No significant differences were observed between patients on CPAP and those not on CPAP, there was no significant difference in hospital stay or rate of respiratory complications. Out of 53 patients who had undergone bariatric surgery at the cut-off date, only 1 had suffered a respiratory complication. Conclusions: Bariatric patients who are screened pre-operatively for OSA and treated according to guidelines have no increased risk of respiratory complications compared to patients without OSA. PMID- 29445539 TI - The clinical usefulness of a self-administered questionnaire for sleep-disordered breathing in patients with neuromuscular disease. AB - Background: Patients with neuromuscular disease (NMD) are at risk of developing sleep-disordered breathing (SDB) with hypercapnic respiratory failure. We hypothesised that a self-administered questionnaire (SiNQ-5 scores) may be useful to assess patients who are established on treatment for NMD with SDB. Methods: Patients attending a tertiary referral centre filled in the SiNQ-5 (range 0-10 points, lower scores indicating fewer symptoms). The questionnaire contains five questions related to breathlessness, sleep and posture. Patients with NMD and treated SDB were compared to NMD without SDB, to sleep apnoea, chronic obstructive pulmonary disease (COPD) and heart failure (HF) patients' scores, as well as a group of patients without SDB. Results were compared using Kruskal Wallis one-way analysis of variance, with Dunn/Bonferroni post-hoc tests if comparisons were found to be statistically significant. Results: A total of 265 (156 male) patients completed the assessment, 40 had NMD with treated SDB [SiNQ-5 score 3.4 (3.0) points], 11 had NMD without SDB [2.7 (2.9) points], 120 patients had obstructive sleep apnoea (OSA) [4.1 (2.6) points], 16 had COPD [3.9 (3.0) points] and 9 had HF [3.2 (2.8) points], 69 patients had other conditions with no evidence of SDB [3.0 (2.4) points; P=0.077]. Patients with NMD without SDB and those with SDB who were on treatment did not differ in their responses (P=0.417). Question #1 allowed discrimination between patients with NMD with SDB [0.8 (0.8) points] and other disorders without respiratory involvement [0.3 (0.6) points; P=0.024]. Conclusions: The SiNQ-5 scores in neuromuscular patients with SDB who are established on treatment and NMD patients without SDB, as well as in patients with other conditions leading to SDB are similar. PMID- 29445540 TI - The effect of positive and negative message framing on short term continuous positive airway pressure compliance in patients with obstructive sleep apnea. AB - Background: Continuous positive airway pressure (CPAP), the best available treatment for obstructive sleep apnea (OSA), requires long-term compliance to be effective. Behavioral interventions may be used to improve adherence to CPAP. We aimed to investigate whether positive or negative message framing impacts on CPAP compliance in patients with OSA, when compared to standard care. Methods: Consenting patients with confirmed OSA were randomly allocated to receive along with their CPAP either positively or negatively framed messages (Pos; Neg), or standard care (Con). Standardized motivational messages were read out to patients during an initial teaching session and through weekly telephone calls. Patients' compliance data were reviewed 2 and 6 weeks following CPAP initiation. Results: We randomized 112 patients to groups that were matched for age, BMI, and OSA severity. The positively framed group (Pos) showed greater CPAP usage after 2 weeks (total use 53.7+/-31.4 hours) as compared to the negatively framed and the control group (35.6+/-27.4 and 40.8+/-33.5 hours, P<0.05); however, no differences were seen at 6 weeks. There were more dropouts in the control group than in either framed groups (Pos n=5; Neg n=8; Con n=11; P<0.05). Conclusions: Positively framed messages can improve CPAP adherence in patients with OSA in the short-term; however, strategies for implementing its long-term use need to be developed. PMID- 29445541 TI - Multiple dimensions of excessive daytime sleepiness. AB - Background: In this study we investigated subjective measures of sleepiness and related our findings to dimensions of affect, fatigue, emotion, mood and quality of life based on a hypothetical multidimensional model of sleepiness. Methods: Patients referred to a sleep clinic were assessed regarding their excessive daytime sleepiness (EDS), sleep complaints, routine and symptoms. Age, gender and body mass index (BMI), the Epworth Sleepiness Scale (ESS), the Stanford Sleepiness Scale (SSS), the Samn-Perelli fatigue Scale (SPS), the Global Vigor and Affect Scale (GVS and GAS, respectively), the Hospital Anxiety and Depression Scale (HADS-A and HADS-D, respectively), and the Positive and Negative Affect Schedule (PAS and NAS, respectively) scores were recorded. Results: Fifty patients [25 male, 45.2 (18.7) years] completed the questionnaires. The ESS scores were positively correlated with SSS, SPS, HADS-A, HADS-D and NAS scores and negatively with GVS and GAS scores (P<0.05). The SPS (P<0.001) and HADS-A scores (P=0.002) were independently associated with the ESS scores (R2=0.532, adjusted R2 =0.4794, P<0.001). Conclusions: A model of sleepiness that assesses dimensions of fatigue and anxiety could explain the symptom of subjective sleepiness better than the isolated use of the ESS. PMID- 29445542 TI - Assessing the sleeping habits of patients in a sleep disorder centre: a review of sleep diary accuracy. AB - Background: Excessive daytime sleepiness (EDS) is a complaint common to many aspects of medicine. There are primary and secondary causes for EDS, with secondary causes including a large number of common conditions. Primary causes, such as narcolepsy, are much rarer. When assessing for primary hypersomnia, restricted or fragmented sleep must be ruled out. This process involves assessment of sleeping habits using a sleep diary and/or actigraphy. Clinicians are suspicious of the accuracy with which patients use the former. This review aims to evaluate the accuracy of a sleep diary study against the 'objective gold standard' actigraphy report. Methods: Data from 35 patients at a Sleep Disorder Centre who underwent both a sleep diary and actigraphy study for suspected primary hypersomnia in 2016 was collected. Mean values of four variables were calculated: 'time of lights out', 'time to fall asleep', 'time of waking' and 'sleep time'. The 'similarity' was assessed. This was a term defined in three different ways: if sleep diary values are accurate to within 20, 30 and 60 min respectively. Percentage 'similarity', mean time differences and standard deviations (SDs) were calculated for each variable. A paired t-test was also performed to assess the significance of the time differences between the two modalities. Results: Least accurate was 'sleep time', with 14.7%, 23.5% and 58.8% of patients within 20, 30 and 60 min of the actigraphy respectively. Mean time difference for this variable was 66 min (versus 33, 15 and 22). 'Time to fall asleep' was most accurate, with 76.5%, 82.4% and 100% 'similarity' respectively. Conclusions: The clinically acceptable accuracy has no universal definition, so clinicians must use experience and reasoning to determine this level to interpret this data. The review suggests that some variables are entered with high accuracy, and the diary is low cost and adds subjective information that cannot be gathered from actigraphy. Therefore, use is recommended to continue alongside actigraphy. PMID- 29445543 TI - Models for Preterm Cortical Development Using Non Invasive Clinical EEG. AB - The objective of this study was to evaluate the piglet and the mouse as model systems for preterm cortical development. According to the clinical context, we used non invasive EEG recordings. As a prerequisite, we developed miniaturized Ag/AgCl electrodes for full band EEG recordings in mice and verified that Urethane had no effect on EEG band power. Since mice are born with a "preterm" brain, we evaluated three age groups: P0/P1, P3/P4 and P13/P14. Our aim was to identify EEG patterns in the somatosensory cortex which are distinguishable between developmental stages and represent a physiologic brain development. In mice, we were able to find clear differences between age groups with a simple power analysis of EEG bands and also for phase locking and power spectral density. Interhemispheric coherence between corresponding regions can only be seen in two week old mice. The canolty maps for piglets as well as for mice show a clear PAC (phase amplitude coupling) pattern during development. From our data it can be concluded that analytic tools relying on network activity, as for example PAC (phase amplitude coupling) are best suited to extract basic EEG patterns of cortical development across species. PMID- 29445544 TI - Telomeric G-Quadruplexes: From Human to Tetrahymena Repeats. AB - The human telomeric and protozoal telomeric sequences differ only in one purine base in their repeats; TTAGGG in telomeric sequences; and TTGGGG in protozoal sequences. In this study, the relationship between G-quadruplexes formed from these repeats and their derivatives is analyzed and compared. The human telomeric DNA sequence G3(T2AG3)3 and related sequences in which each adenine base has been systematically replaced by a guanine were investigated; the result is Tetrahymena repeats. The substitution does not affect the formation of G-quadruplexes but may cause differences in topology. The results also show that the stability of the substituted derivatives increased in sequences with greater number of substitutions. In addition, most of the sequences containing imperfections in repeats which were analyzed in this study also occur in human and Tetrahymena genomes. Generally, the presence of G-quadruplex structures in any organism is a source of limitations during the life cycle. Therefore, a fuller understanding of the influence of base substitution on the structural variability of G quadruplexes would be of considerable scientific value. PMID- 29445545 TI - HIV-Stigma in Nigeria: Review of Research Studies, Policies, and Programmes. AB - Nigeria has about 3.8 million people living with HIV, the second largest globally. Stigma and discrimination are major barriers to testing, treatment uptake, and adherence. In this review, we synthesized information on research studies, policies, and programmes related to HIV-stigma in Nigeria. This was with a view to identify critical areas that research and programmes must address in order to accelerate the progress towards zero (new infections, discrimination, and death) target by year 2030. Existing studies were mostly devoted to stigma assessment using varieties of measures. Research, policies, and programmes in the past two decades have made very useful contributions to stigma reduction. We identified the need for a consistent, valid, and objective measure of stigma at different levels of the HIV response. Nigeria does not lack relevant policies; what needs to be strengthened are design, planning, implementation, monitoring, and evaluation of context-specific stigma reduction programmes. PMID- 29445546 TI - Circulating Angiogenic Growth Factors in Diabetes Patients with Peripheral Arterial Disease and Exertional Leg Pain in Ghana. AB - Objective: Peripheral arterial disease (PAD) is a common complication of diabetes, associated with impairment in angiogenesis. Angiogenesis is regulated by angiogenic growth factors such as angiopoietin 1 (Ang-1), Ang-2, and vascular endothelial growth factor (VEGF). We studied the association between angiogenic growth factors versus PAD and exertional leg symptoms in diabetes patients in Ghana. Method: In this cross-sectional study, ankle-brachial index was measured with oscillometrically and exertional leg symptoms were screened with Edinburgh claudication questionnaire in 140 diabetes patients and 110 nondiabetes individuals. Circulating levels of Ang-1, Ang-2, and VEGF were measured with immunosorbent assay. Results: The prevalence of PAD and exertional leg pain was 16.8% and 24.8%, respectively. Compared to non-PAD participants, PAD patients had higher VEGF levels [85.8 (37.5-154.5) versus 57.7 (16.6-161.1) p = 0.032] and lower Ang-1 levels [31.3 (24.8-42.6) versus 40.9 (28.2-62.1), p = 0.017]. In multivariable logistic regression, patients with exertional leg pain had increased the odds of plasma Ang-2 levels [OR (95% CI): 2.08 (1.08-6.41), p = 0.036]. Conclusion: Diabetes patients with PAD and exertional leg pain have imbalance in angiogenic growth factors, indicating impaired angiogenesis. In patients with exertional leg pains, Ang-2 may be an important biomarker. PMID- 29445548 TI - Comparison of Algorithms for the Detection of Enteroviruses in Stool Specimens from Children Diagnosed with Acute Flaccid Paralysis. AB - This study was designed to compare both the cell culture dependent and independent enterovirus detection algorithms recommended by the WHO and assess how either might impact our perception of the diversity of enterovirus types present in a sample. Sixteen paired samples (16 isolates from RD cell culture and their corresponding stool suspension, i.e., 32 samples) from AFP cases in Nigeria were analyzed in this study. All the samples were subjected to RNA extraction, cDNA synthesis, the WHO recommended RT-snPCR, and its modification. Amplicons were sequenced and strains identified. Enterovirus diversity was the same between the isolates and fecal suspension for the control and five of the samples. It was, however, different for the remaining 10 (62.5%) samples. Nine (CV-B4, E6, E7, E13, E14, E19, E29, EV-B75, and EV-B77) and five (CV-A1, CV-A11, CV-A13, EV C99, and PV2) EV-B and EV-C types, respectively, were detected. Particularly, E19 and EV-B75 were only recovered from the isolates while E14, EV-B77, CV-A11, and CV-A13 were only recovered from fecal suspension. Both the cell culture dependent and independent protocols bias our perception of the diversity of enterovirus types present in a sample. Hence, effort should be directed at harmonizing both for increased sensitivity. PMID- 29445547 TI - Temporal Regulation of fim Genes in Uropathogenic Escherichia coli during Infection of the Murine Urinary Tract. AB - Uropathogenic Escherichia coli (UPEC) adhere to cells in the human urinary tract via type 1 pili that undergo phase variation where a 314-bp fimS DNA element flips between Phase-ON and Phase-OFF orientations through two site-specific recombinases, FimB and FimE. Three fim-lux operon transcriptional fusions were created and moved into the clinical UPEC isolate NU149 to determine their temporal regulation in UPEC growing in the urinary tract. Within murine urinary tracts, the UPEC strains demonstrated elevated transcription of fimA and fimB early in the infection, but lower transcription by the fifth day in murine kidneys. In contrast, fimE transcription was much lower than either fimA or fimB early, increased markedly at 24 h after inoculation, and then dropped five days after inoculation. Positioning of fimS was primarily in the Phase-ON position over the time span in UPEC infected bladders, whereas in UPEC infected murine kidneys the Phase-OFF orientation was favored by the fifth day after inoculation. Hemagglutination titers with guinea pig erythrocytes remained constant in UPEC growing in infected murine bladders but fell substantially in UPEC infected kidneys over time. Our results show temporal in vivo regulation of fim gene expression in different environmental niches when UPEC infects the murine urinary tract.

PMID- 29445549 TI - Relationship between Insulin Levels and Nonpsychotic Dementia: A Systematic Review and Meta-Analysis. AB - Objectives: To explore the relationship between insulin levels and nonpsychotic dementia. Methods: Six electronic databases (PubMed, Cochrane, SCI, CNKI, VIP, and Wanfang) were searched from January 1, 2007, to March 1, 2017. Experimental or observational studies that enrolled people with nonpsychotic dementia or abnormal insulin levels in which insulin levels or MMSE scores (events in nonpsychotic dementia) were the outcome measures. Random-effects models were chosen for this meta-analysis. Sample size, mean, s.d., and events were primarily used to generate effect sizes (with the PRIMA registration number CRD42017069860). Results: 50 articles met the final inclusion criteria. Insulin levels in cerebrospinal fluid were lower (Hedges' g = 1.196, 95% CI = 0.238 to 2.514, and P = 0.014), while the levels in peripheral blood were higher in nonpsychotic dementia patients (Hedges' g = 0.853 and 95% CI = 0.579 to 1.127), and MMSE scores were significantly lower in the high insulin group than in the healthy control group (Hedges' g = 0.334, 95% CI = 0.249 to 0.419, and P = 0.000). Conclusions: Our comprehensive results indicate that blood insulin levels may increase in patients with nonpsychotic dementia. PMID- 29445552 TI - Oncocytes in Mucoepidermoid Carcinoma of the Palate: Diagnostic Challenges. AB - The origin of a salivary gland tumour is attributed to cells at various levels of differentiation which present histologically as diverse tissues and cellular patterns. Mitochondria-rich, eosinophilic oncocytes are cells commonly encountered in salivary gland neoplasms. We report a case of mucoepidermoid carcinoma (MEC) in the palate of a 43-year-old female that exhibited a prominent oncocytic component. While the parotid and submandibular glands have been reported as predominant sites for oncocytic MEC (OMEC), the palate and minor salivary glands are rare sites for occurrence. Also, most of the reported cases of OMEC have been histologically of low-grade mucoepidermoid carcinoma with large cystic spaces and good prognosis. In this article, we discuss the differential diagnosis and diagnostic workup of an MEC presenting with oncocytes. PMID- 29445551 TI - Effects of Various Extents of High-Frequency Hearing Loss on Speech Recognition and Gap Detection at Low Frequencies in Patients with Sensorineural Hearing Loss. AB - This study explored whether the time-compressed speech perception varied with the degree of hearing loss in high-frequency sensorineural hearing loss (HF SNHL) individuals. 65 HF SNHL individuals with different cutoff frequencies were recruited and further divided into mildly, moderately, and/or severely affected subgroups in terms of the averaged thresholds of all frequencies exhibiting hearing loss. Time-compressed speech recognition scores under both quiet and noisy conditions and gap detection thresholds within low frequencies that had normal thresholds were obtained from all patients and compared with data from 11 age-matched individuals with normal hearing threshold at all frequencies. Correlations of the time-compressed speech recognition scores with the extents of HF SNHL and with the 1 kHz gap detection thresholds were studied across all participants. We found that the time-compressed speech recognition scores were significantly affected by and correlated with the extents of HF SNHL. The time compressed speech recognition scores also correlated with the 1 kHz gap detection thresholds except when the compression ratio of speech was 0.8 under quiet condition. Above all, the extents of HF SNHL were significantly correlated with the 1 kHz gap thresholds. PMID- 29445553 TI - S. lugdunensis Native-Joint Septic Arthritis: Case Report and Review of the Literature. AB - Staphylococcus lugdunensis is a skin commensal classified as a coagulase-negative Staphylococcus (CoNS). Though CoNS is typically associated with less aggressive clinical disease than Staphylococcus aureus, there is growing awareness that S. lugdunensis may be as virulent as S. aureus. The association between S. lugdunensis and infective endocarditis is well known, but few reports of native joint disease with this organism exist. We report a case a 28-year-old male with no prior medical problems presenting with native-joint septic arthritis. Cultures grew S. lugdunensis. To our knowledge, this is the fifth case reported in the literature. PMID- 29445554 TI - Ogilvie's Syndrome after Cesarean Section: Case Report in Saudi Arabia and Management Approach. AB - Background: Acute colonic pseudoobstruction or Ogilvie's syndrome is a rare entity that is characterized by acute dilatation of the colon without any mechanical obstruction. It is usually associated with medical disease or surgery and rarely occurs spontaneously. If not diagnosed early, Ogilvie's syndrome may cause bowel ischemia and perforation. Case: A G7P4+2, 40-year-old woman, who is a known case of gestational diabetes mellitus during her current pregnancy, four previous cesarean sections, two early pregnancy losses at six-week gestation, and hypothyroidism, underwent uncomplicated elective cesarean section, after which she complained of abdominal distention. Conclusion: Ogilvie's syndrome is a rare condition yet of interest to obstetricians, midwifery staff, and general surgeons because its early diagnosis and prompt treatment are the keystones to avoid any subsequent fatal complications. This case report reviews the clinical characteristics, diagnostic methods, and management of Ogilvie's syndrome. Moreover, we suggest a management approach to help in early diagnosis and prompt management to improve the outcome of this potentially serious condition. PMID- 29445555 TI - Metastatic Recurrence of Typical Pulmonary Carcinoid Accompanied by Carcinoid Syndrome, Successfully Treated with Octreotide LAR. AB - We present a case of metastatic recurrence of carcinoid tumor accompanied by carcinoid syndrome in a 68-year-old Japanese man, 12 years after resection of typical pulmonary carcinoid. Histopathologic examination from percutaneous liver biopsy revealed metastatic typical carcinoid. Clinical symptoms gradually improved after administration of octreotide LAR. Two years after starting treatment, the disease remains well controlled. This case report illustrates the possibility of antiproliferative effects of octreotide LAR on typical pulmonary carcinoid. PMID- 29445556 TI - Immunotherapy for Metastatic Melanoma with Right Atrial Involvement in a Patient with Rheumatoid Arthritis. AB - Prognosis for metastatic melanoma has improved significantly with the use of immune checkpoint inhibitors. Given improvements in survival, aggressive surgical treatment may be considered in patients with life-threatening complications from their disease that would not otherwise be considered in advanced disease. Patients with preexisting autoimmune diseases or prior immune-related adverse events from therapy are largely excluded from clinical trials. Concerns exist that immunotherapy in these patients could worsen autoimmune disease or increase the risk of developing additional immune-related adverse events on therapy. We present a case of a patient with rheumatoid arthritis that presented with obstructive heart failure secondary to melanoma that had metastasized to the right atrium. After aggressive surgical resection to stabilize him from his life threatening heart failure, he was treated with ipilimumab, which was stopped due to an immune-related adverse event. He was then started on pembrolizumab and had a durable response to therapy. Aggressive surgical treatment should be considered in patients with a cancer that may respond to immunotherapy. Furthermore, some patients with preexisting autoimmune disease may be safely treated with checkpoint inhibition therapy, and patients with a severe immune toxicity from one class may successfully be treated with an alternate class. PMID- 29445557 TI - Benign Recurrent Sixth Nerve Palsy in a Child. AB - Benign recurrent sixth nerve palsy in children is rare. It typically occurs following viral illness or immunization, and prognosis is usually excellent. However, it is always a diagnosis of exclusion given the more serious alternative causes. Therefore, a thorough examination with brain imaging is recommended. The authors report a child with six recurrent episodes of isolated benign sixth nerve palsy. PMID- 29445558 TI - Delayed Radial Nerve Palsy after Closed Reduction of a Pediatric Humeral Shaft Fracture. AB - Humeral shaft fractures are common in the United States and may be associated with radial nerve injuries due to their close anatomic relationship in the spiral groove. Most radial nerve palsies are found at presentation due to the initial trauma; however, they can present secondary to orthopaedic intervention following reduction. In this case report, we present a case of delayed radial nerve palsy in a pediatric patient that was identified four days after closed reduction and splinting which required open reduction, nerve exploration, and internal fixation. Fortunately, full motor and sensory recovery was observed at 6 weeks post-op. A unique aspect of this case is that immediate postreduction exam in the emergency department showed no signs of injury or entrapment of the radial nerve. PMID- 29445559 TI - A Rare Case Report and Literature Review of External Auditory Canal Cholesteatoma with Circumferential Destruction of Canal Wall Exposing Facial Nerve. AB - External auditory canal cholesteatoma (EACC) is a rare condition with an estimated incidence of 1.2 per 1000 new otological patients. It is often mistaken with keratosis obturans. We discuss an extensive primary EACC with an aural polyp in a male which was managed by modified radical mastoidectomy. PMID- 29445560 TI - The Partial Duplication of the 5' Segment of KMT2A Revealed KMT2A-MLLT10 Rearrangement in a Boy with Acute Myeloid Leukemia. AB - The duplication of 5' segment of KMT2A is a rare molecular event in childhood leukemia, and the influence on prognosis is unknown. Here, we report on a boy who developed acute monocytic leukemia. Fluorescence in situ hybridization revealed the duplication of the 5' segment with 2 normal alleles at KMT2A which was eventually found to be fused with MLLT10. Chemotherapy promptly induced the first complete remission in the patient at our facility, and the patient remained in first complete remission with negative minimal residual disease at 3.5 years from diagnosis. Our case is similar to two previously reported patients who had partial duplication of the 5' segment of KMT2A with a KMT2A-MLLT10 rearrangement. Further studies and experience with this cryptic translocation may shed more light on the management of acute myeloid leukemia. PMID- 29445561 TI - Thoracic Paravertebral Mass as an Infrequent Manifestation of IgG4-Related Disease. AB - Case: A 50-year-old African American male presented with abdominal pain and significant weight loss. On physical examination, he had parotid and submandibular gland enlargement associated with right eye proptosis. Computed tomography showed a thoracic paravertebral soft tissue mass, enlarged lymph nodes, and ascending aortic aneurysm. Laboratory results were remarkable for elevated total IgG and IgG4 subclass. The submandibular gland pathology revealed chronic sclerosing sialadenitis, with a large subset of inflammatory cells positively staining for IgG4. The histology of the paravertebral mass demonstrated fibrosclerosis with increased lymphocytic infiltrate, associated with increased IgG4 plasma cells. He was diagnosed with immunoglobulin G4-related disease (IgG4-RD). Steroid therapy initially yielded improvement; however, after steroids were stopped, there was disease recurrence. Prednisone was restarted, and the plan was to start him on rituximab. Interestingly, the patient's brother also had IgG4-RD. Conclusion: IgG4-RD can present as a paravertebral mass which is usually responsive to steroids; however, recurrent and resistant disease can be seen for which steroid-sparing agents such as rituximab should be considered. In addition, to the best of our knowledge, this is the first reported case of IgG4-RD in two family members presenting as a paravertebral mass, highlighting an exciting area for more research in the future.

PMID- 29445563 TI - Eculizumab for Thrombotic Microangiopathy Associated with Antibody-Mediated Rejection after ABO-Incompatible Kidney Transplantation. AB - Thrombotic microangiopathy is a form of antibody-mediated rejection (ABMR): it is the main complication of ABO-incompatible (ABOi) kidney transplantation (KT). Herein, we report on two cases of ABMR with biological and histological features of thrombotic microangiopathy (TMA) that were treated by eculizumab after ABOi KT. The first patient presented with features of TMA at postoperative day (POD) 13. Because of worsening biological parameters and no recovery of kidney function, despite seven sessions of immunoadsorption, a salvage therapy of eculizumab was started on POD 23. Kidney function slightly improved during the first 4 months after transplantation. Eculizumab was stopped at month 4. However, kidney function worsened progressively, leading to dialysis at month 13 after transplantation. The second patient presented with features of TMA at POD 1. In addition to immunoadsorption therapy, eculizumab was started on POD 6. Kidney function improved. Eculizumab was stopped on POD 64 and immunoadsorption sessions were stopped on POD 102. At the last follow-up (after 9 months), eGFR was at 43 mL/min/1.73 m2. Our case reports show the beneficial effect of eculizumab to treat ABMR after ABOi KT. However, it should be given early after diagnosing TMA associated with ABMR. PMID- 29445564 TI - 3-DOF Force-Sensing Micro-Forceps for Robot-Assisted Membrane Peeling: Intrinsic Actuation Force Modeling. AB - Membrane peeling is a challenging procedure in retinal microsurgery, requiring careful manipulation of delicate tissues by using a micro-forceps and exerting very fine forces that are mostly imperceptible to the surgeon. Previously, we developed a micro-forceps with three integrated fiber Bragg grating (FBG) sensors to sense the lateral forces at the instrument's tip. However, importantly this architecture was insufficient to sense the tissue pulling forces along the forceps axis, which may be significant during membrane peeling. Our previous 3 DOF force sensing solutions developed for pick tools are not appropriate for forceps tools due to the motion and intrinsic forces that develop while opening/closing the forceps jaws. This paper presents a new design that adds another FBG attached to the forceps jaws to measure the axial loads. This involves not only the external tool-to-tissue interactions that we need to measure, but also the adverse effect of intrinsic actuation forces that arise due to the elastic deformation of jaws and friction. In this study, through experiments and finite element analyses, we model the intrinsic actuation force. We investigate the effect of the coefficient of friction and material type (stainless steel, titanium, nitinol) on this model. Then, the obtained model is used to separate the axial tool-to-tissue forces from the raw sensor measurements. Preliminary experiments and simulation results indicate that the developed linear model based on the actuation displacement is feasible to accurately predict the axial forces at the tool tip. PMID- 29445566 TI - Patients affected by endemic pemphigus foliaceus in Colombia, South America exhibit autoantibodies to optic nerve sheath envelope cell junctions. AB - Background: The majority of the patients affected by a new variant of endemic pemphigus foliaceus in El Bagre, Colombia (El Bagre EPF or pemphigus Abreu-Manu), have experienced vision problems; we have previously reported several ocular abnormalities. Methods: Here, we aimed to investigate reactivity to optic nerves in these patients. We utilized bovine, rat and mouse optic nerves, and performed immunofluorescence and confocal microscopy to test for optical nerve autoreactivity. We tested 45 patients affected by this disease and 45 controls from the endemic area matched by age, sex and work activity. Results: Overall, 37 of the 45 patient sera reacted to the optic nerve envelope that is composed of leptomeninges; the reactivity was polyclonal and present mostly at the cell junctions (P < 0.001). The immune response was directed against optic nerve sheath cell junctions and the vessels inside it, as well as other molecules inside the nerve. No control cases were positive. Of interest, all the patient autoantibodies co-localized with commercial antibodies to desmoplakins I-II, myocardium-enriched zonula occludens-1- associated protein (MYZAP), armadillo repeat gene deleted in velo-cardio-facial syndrome (ARVCF), and plakophilin-4 (p0071) from Progen Biotechnik (P < 0.001). Conclusion: We conclude that the majority of the patients affected by pemphigus Abreu-Manu have autoantibodies to optic nerve sheath envelope cell junctions. These antibodies also co-localize with armadillo repeat gene deleted in velo-cardio-facial syndrome, p0071 and desmoplakins I-II. The clinical significance of our findings remains unknown. PMID- 29445565 TI - Super-Resolution Community Detection for Layer-Aggregated Multilayer Networks. AB - Applied network science often involves preprocessing network data before applying a network-analysis method, and there is typically a theoretical disconnect between these steps. For example, it is common to aggregate time-varying network data into windows prior to analysis, and the trade-offs of this preprocessing are not well understood. Focusing on the problem of detecting small communities in multilayer networks, we study the effects of layer aggregation by developing random-matrix theory for modularity matrices associated with layer-aggregated networks with N nodes and L layers, which are drawn from an ensemble of Erdos Renyi networks with communities planted in subsets of layers. We study phase transitions in which eigenvectors localize onto communities (allowing their detection) and which occur for a given community provided its size surpasses a detectability limit K* . When layers are aggregated via a summation, we obtain [Formula: see text], where T is the number of layers across which the community persists. Interestingly, if T is allowed to vary with L, then summation-based layer aggregation enhances small-community detection even if the community persists across a vanishing fraction of layers, provided that T/L decays more slowly than ??(L-1/2). Moreover, we find that thresholding the summation can, in some cases, cause K* to decay exponentially, decreasing by orders of magnitude in a phenomenon we call super-resolution community detection. In other words, layer aggregation with thresholding is a nonlinear data filter enabling detection of communities that are otherwise too small to detect. Importantly, different thresholds generally enhance the detectability of communities having different properties, illustrating that community detection can be obscured if one analyzes network data using a single threshold. PMID- 29445567 TI - An unusual lesion on the nose: microvenular hemangioma. AB - Microvenular hemangioma (MVH) is an acquired, benign type of hemangioma that usually manifests itself as a solitary, slowly growing, red to violaceous, asymptomatic papule, plaque or nodule. It is typically located on the trunk or extremities of young adults. It can be difficult to differentiate MVH from other types of hemangioma and Kaposi sarcoma. Herein we report a case of MVH unusual for its location, age of onset, and morphologic features. A 62-year-old man complained of an asymptomatic, bluish-red discoloration on the tip of his nose that had been present for two years. Dermatologic examination showed a violaceous patch 2 * 2 cm in diameter with indistinct borders. Incisional biopsy revealed irregularly branched small or medium-sized vascular spaces lined with benign endothelial cells, positive for CD34 and negative for HHV-8. MVH is a rare lesion, and less than 70 cases have been published to date. A review of 40 reported cases revealed that 15% of MVH patients were over 40 years of age and only 3% of the cases showed macules or patches. A literature survey showed only two cases of MVH located on the facial region, one on the chin and the other on the cheek. Our case was unique for its location and interesting for other rarely encountered features. MVH should be considered in the differential diagnoses of vascular lesions on nasal skin. PMID- 29445569 TI - Glutathione for skin lightening: a regnant myth or evidence-based verity? AB - The recent hype surrounding the antimelanogenic properties of glutathione has resulted in physicians frequently administering it as a "wonder" drug for skin lightening and treatment of hyperpigmentation, especially in ethnic populations with darker skin tones. This phenomenon has seen a recent surge owing to aggressive marketing and capitalization of pharma-cosmeceutical companies. However, the unbridled and prodigal use of it, especially as a parenteral formulation, seems unjustified, given the lacunae in our knowledge about its antimelanogenic potential, limited clinical evidence favoring its role in skin lightening, and the statutory ban/advisory issued by certain federal agencies. Even though parenteral glutathione is approved only for severe liver disorders and for prevention of chemotherapy associated neurotoxicity, the lack of statutory laws governing the use of systemic glutathione in most countries has contributed to its unchecked use for skin lightening. The current clinical evidence of intravenous glutathione for skin lightening is limited to a single study with a dubious study design and apparently flawed analysis of results, casting doubt on the drug's efficacy and reported adverse effects. Two studies evaluating oral/sublingual administration and one trial involving the use of topical glutathione reported good safety profile and appreciable but reversible results on skin tone. In this article, we shall review and discuss the current status of glutathione as a skin lightening agent and address the sundry unanswered queries regarding the dosage, duration of use and longevity of accrued effects based on clinical evidence and recent insights into its antimelanogenic mechanism.

AB - Collagenoma is a type of connective tissue nevi, a rare hamartomatous malformation characterized by the predominant proliferation of normal collagen fibers and normal, decreased, or increased elastic fibers. Collagenomas present as multiple or solitary, hereditary or sporadic, asymptomatic, skin-colored papules, nodules, and plaques with variable sizes, and are usually located on the trunk, arm, and back. Here, we report on a 14-year-old boy who presented with an isolated giant collagenoma of the frontal area that dramatically responded to intralesional triamcinolone acetonide. PMID- 29445570 TI - A new perspective on the nail plate for treatment of ingrown toenail. AB - Background: Our routine treatment for ingrown toenail was removal of the surrounding soft tissue and shortening the bone of the distal phalanx. We determined the range and volume of excision based on our experience without an objective standard and routinely performed avulsion of the nail plate. Objective: To take the nail plate as an objective mark during surgical treatment of ingrown toenail to ensure accurate excision. Patients and Methods: Fifteen patients with ingrown toenails were treated with this technique. We used the lateral borders of the nail plate as a landmark to determine the volume of soft tissue surrounding the nail plate and distal phalanx to be removed. No avulsion of nail plate was performed. Results: No recurrence was observed during the follow-up period, which ranged from 24 to 35 months (29.9 months on average). The visual analog scale for pain showed significant pain relief in the patients. The Vancouver Scar Scale showed acceptable cosmetic outcomes. The width of excised skin ranged from 3.5 to 6.2 mm (5.0 mm on average). Conclusion: The use of the lateral borders of the nail plate as a landmark for surgical intervention of ingrown toenail offered excellent outcomes and reduced loss of healthy tissues. PMID- 29445571 TI - Immunoreactivity of Wilms tumor 1 (WT1) as an additional evidence supporting hemangiomatous rather than inflammatory origin in the etiopathogenesis of angiolymphoid hyperplasia with eosinophilia. AB - Background: Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare vascular proliferative disorder mainly located in the periauricular region. The etiopathogenesis of ALHE is unknown, and it is still controversial as to whether the entity represents a benign vascular neoplasm or an inflammatory process. Aim: Recently, the intracytoplasmic staining pattern of Wilms tumor 1 (WT1) on immunohistochemistry has highlighted true vascular neoplasms, such as microvenular hemangioma, tufted angioma, and spindle cell hemangioma, which has made it helpful to distinguish ALHE from vascular malformations, as there is a negative staining pattern in the other entities. We aimed to investigate the immunoreactivity of ALHE specimens for WT1 as well as glucose transporter protein 1 (GLUT1) immunohistochemistry, an important and sensitive marker for the diagnosis of infantile hemangioma, which recently has been described to label other hemangiomas, such as verrucous hemangioma. Material and methods: Clinical data and histopathological specimens from patients diagnosed with ALHE were reviewed, and immunohistochemical staining and microscopic analysis for WT-1 and GLUT1 were performed. Results: Intracytoplasmic endothelial staining of WT1 was detected in 19 of 20 ALHE specimens. GLUT1 was not detected in any ALHE specimen. Conclusions: We conclude that ALHE may represent a true hemangioma (i.e., benign vascular neoplasia) characterized by an eosinophil- and lymphocyte-rich inflammatory component as opposed to the reactive inflammatory dermatosis with a positive intracytoplasmic staining pattern for WT1. As far as we are aware, WT1 staining for ALHE has not been described to date. PMID- 29445572 TI - Dermoscopy of a rare case of linear syringocystadenoma papilliferum with review of the literature.

AB - LEOPARD syndrome, also known as Gorlin syndrome II, cardiocutaneous syndrome, lentiginosis profusa syndrome, Moynahan syndrome, was more recently coined as Noonan syndrome with multiple lentigines (NSML), inside the RASopathies. Historically, the acronym LEOPARD refers to the presence of distinctive clinical features such as: lentigines (L), electrocardiographic/conduction abnormalities (E), ocular hypertelorism (O), pulmonary stenosis (P), genital abnormalities (A), retardation of growth (R), and sensorineural deafness (D). This condition is identified in 85% of patients with phenotype hallmarks caused by presence a germline point mutation in PTPN11 gene. Association of melanoma to NSML seems to be rare: to our knowledge, two patients so far were reported in the literature. We herein present a patient diagnosed with LEOPARD syndrome, in whom molecular investigation confirmed the presence of the c.1403C>T mutation in exon 12 of the PTPN11 gene, who developed four superficial spreading melanomas and three atypical lentiginous hyperplasias. Three of the melanomas were achromic or hypochromic, three were in situ, and one had a Breslow index under 0.5 mm. Dermoscopic examination showed some characteristic white structures in most of the lesions, which were a signature pattern and a key for the diagnosis.

PMID- 29445581 TI - Eruptive nevi after burn injury. AB - Eruptive melanocytic nevi (EMN) is an unusual phenomenon characterized by the abrupt development of multiple melanocytic nevi over weeks to months in association with an underlying trigger. The underlying mechanisms are not fully understood, however, they have been associated with a variety of conditions. EMN is relatively uncommon and might be underreported due to the absence of close monitoring, insufficient recognition, and the presumed benign course of the condition. We describe the first case report of acral EMN associated with a burn wound on a 2-year-old child. Familiarity is important to differentiate EMN from neoplasms.

Its genital localization is rare, and the diagnosis in this site could be challenging. Here, we report two patients with vulvar BCC and describe their clinical, dermoscopic and in vivo and ex vivo reflectance confocal microscopic (RCM) features. Dermoscopy and RCM can be useful tools for helping the clinical diagnosis of vulvar BCC and for identifying the correct surgical margins. PMID- 29445583 TI - Deep sustained response to daratumumab monotherapy associated with T-cell expansion in triple refractory myeloma. AB - Background: Daratumumab, a human CD38 monoclonal antibody that has direct on tumor and immunomodulatory mechanisms of action, demonstrated clinical benefit as monotherapy or in combination with established regimens in patients with multiple myeloma with one or more prior lines of therapy. Case presentation: A male patient, who was 70 years of age at the time of diagnosis of multiple myeloma in 2011, relapsed after five lines of therapy, including autologous stem cell transplantation. The patient's disease, which was considered high risk with a deletion of chromosome 17p, advanced quickly and was triple refractory 2 years after diagnosis leaving few treatment options. He was treated with daratumumab monotherapy in the SIRIUS clinical trial resulting in a stringent complete response and clearance of minimal residual disease. The duration of the patient's clinical response is now over 3.5 years without relapse, compared with a median of 7.6 months for similarly treated patients. The patient's immunophenotype revealed CD8+ T-cell expansion, clonal expansion of the T-cell receptor repertoire, and decreases in regulatory T cells during daratumumab therapy, suggesting a robust adaptive immune response. This immune response was still present 32 months into daratumumab therapy. Conclusions: The results from this case report showed that a patient with advanced multiple myeloma, who had exhausted all treatment options with existing regimens, mounted an ongoing, deep, and durable response to daratumumab monotherapy. Further investigation of the immunologic profile provided additional patient-level evidence of an immunomodulatory mechanism of action of daratumumab.Trial registration ClinicalTrials.gov Identifier number NCT01985126.

AB - Acid-sensing ion channel 1a (ASIC1a) participates in human intervertebral disc degeneration (IVDD) and regulates the destiny of nucleus pulposus cells (NPCs) in acid stimulus. However, the mechanism of ASIC1a activation and its downstream pathway remain unclear. Endoplasmic reticulum (ER) stress also participates in the acid-induced apoptosis of NPCs. The main purpose of this study was to investigate whether there is any connection between ASIC1a and ER stress in an acid-induced nucleus pulposus degeneration model. The IVDs of Sprague-Dawley rats were stained by immunohistochemical staining to evaluate the expression of ASIC1a in normal and degenerated rat nucleus pulposus. ASIC1a expression was also quantified by quantitative real-time-polymerase chain reaction and Western blotting analysis. NPCs were exposed to the culture media with acidity at pH 7.2 and 6.5 for 24 h, with or without 4-phenylbutyrate (4-PBA, a blocker of the ER stress pathway). Cell apoptosis was examined by Annexin V/Propidium Iodide (PI) staining and was quantified using flow cytometry analysis. ASIC1a-mediated intracellular calcium was determined by Ca2+ imaging using Fura-2-AM. Acidity induced changes in ER stress markers were studied using Western blotting analysis. In vivo, ASIC1a expression was upregulated in natural degeneration. In vitro, acid stimulus increased intracellular calcium levels, but this effect was blocked by knockdown of ASIC1a, and this reversal was partly inhibited by 4-PBA. In addition, blockade of ASIC1a reduced expression of ER stress markers, especially the proapoptotic markers. ASIC1a partly regulates ER stress and promotes apoptosis of NPCs under acid stimulus and may be a novel therapeutic target in IVDD. PMID- 29445585 TI - Engineered Human Stem Cell Microenvironments. AB - Stem cells have the ability to self-renew and differentiate into specialized cell types, and, in the human body, they reside in specialized microenvironments called "stem cell niches." Although several niches have been described and studied in vivo, their functional replication in vitro is still incomplete. The in vitro culture of pluripotent stem cells may represent one of the most advanced examples in the effort to create an artificial or synthetic stem cell niche. A focus has been placed on the development of human stem cell microenvironments due to their significant clinical implications, in addition to the potential differences between animal and human cells. In this concise review we describe the advances in human pluripotent stem cell culture, and explore the idea that the knowledge gained from this model could be replicated to create synthetic niches for other human stem cell populations, which have proven difficult to maintain in vitro. PMID- 29445587 TI - Training in robotic thoracic surgery. AB - The best way to teach robotic thoracic surgery is still being decided. New trainees, experienced video-assisted thoracoscopic surgery (VATS) surgeons, and predominantly open surgeons each have different needs when it comes to learning robotic surgery. The data shows that the learning curve and ability to learn robotics initially appears to be shorter and easier than surgeons learning VATS. Though the absolute best method for teaching is still under investigation, multiple centers have started to create systematic methods of teaching robotic surgery that increases resident autonomy while still protecting the patient. PMID- 29445588 TI - The Very Experienced Time-honoUred Surgeons (VETUS) project. AB - Senior surgeons who completed their formal surgical training before the video assisted thoracoscopic surgery (VATS) lobectomy era have had more experience with lobectomy via thoracotomy while their thoracoscopic training background contrasts from younger surgeons. However, this does not seem to have an unfavourable effect on their performance. Despite the literature recognising the critical points of influence of the learning curve for resident surgeons, limited data are focusing on the incremental performance of VATS lobectomy by senior surgeons. The Very Experienced Time-honoUred Surgeons (VETUS) project aims to understand this trend in the VATS group and to introduce an approach to the VATS lobectomy involving senior surgeon. The VETUS project is based on a self-assessment program where the senior surgeon (independently and in complete anonymity) follows a 1-year approach to training in VATS lobectomy. At predefined time intervals, the surgeon will be called to evaluate his performance according to a number of variables such as the choice of VATS lobectomy indications, the number of the port used and length of utility incision, time spent in dissecting the hilar structures and the overall percentage of VATS lobectomy performed in 1 year compared to open. The self-assessment of the VETUS project is a unique opportunity to define the path of a systematic approach to training outside the traditional modalities with the ultimate aim of supporting quality of standardised VATS lobectomy throughout the country. PMID- 29445586 TI - Stressed Out - Therapeutic Implications of ER Stress Related Cancer Research. AB - The unfolded protein response (UPR) is an established and well-studied cellular response to the stress and serves to relieve the stress and reinstate cellular homeostasis. It occurs in the endoplasmic reticulum (ER), responsible of properly folding and processing of secretory and transmembrane proteins. It is extremely sensitive to alteration in homeostasis caused by various internal or external stressors which leads to accumulation of misfolded or unfolded proteins in the ER lumen. The UPR works by restoring protein homeostasis in the ER, either through the boosting of protein-folding and degradation capability or by assuaging the demands for such effects, and can cause the activation of cell death if unable to do so. Cancer cells have adapted to gain advantage from the UPR and keeping the cell away from apoptosis and promoting survival, including survival of the cancer stem cells and evading the immune system. Several components of the UPR are overexpressed in a malignant cell and are responsible for resistance from various chemotherapy options and radiotherapy, which are also responsible for causing ER stress and activating the UPR. In this review, we discuss the various ways in which UPR can aid different cancers to survive and evade therapy and highlight recent research, which exploits the UPR to confer sensitivity to these cancer cells against various drugs and radiation.

PMID- 29445590 TI - Enhanced recovery after surgery (ERAS) and fast-track in video-assisted thoracic surgery (VATS) lobectomy: preoperative optimisation and care-plans. AB - Main specific interventions for preoperative clinical optimisation of patients undergoing lung cancer surgery include assessment and treatment of comorbidities, minimizing preoperative hospitalization, minimizing preoperative fasting, and optimisation of antibiotic and thrombo-embolic prophylaxis. Preoperative patient optimisation is considered a crucial part of enhanced recovery after thoracic surgery pathways. Potentially, advantages of this fast-track management could be even higher when considering video-assisted thoracic surgery (VATS) major lung resection, because reduced trauma related to minimally invasive techniques is one of the main factors improving postoperative outcome. Literature data and clinical evidences in this setting are reported and discussed. PMID- 29445591 TI - The time for VATS segmentectomy has come.

This is the preferable procedure for central typical carcinoid tumour located closed to the carina. PMID- 29445593 TI - Minimally invasive techniques in thymic surgery: a worldwide perspective. AB - Minimally invasive surgical techniques are important in surgical management of thymic pathologies. Traditional access techniques are being replaced with minimally invasive techniques using multiportal or uniportal approach. Adoption of minimally invasive techniques for thymic malignancies has been slow due to long term recurrence concerns. Recent studies show that minimally invasive video assisted thoracoscopic surgery (VATS) or robotic approach to early stage thymic malignancies are associated with less intraoperative bleeding, lower rate of respiratory complications, shorter chest tube duration and shorter hospital stay. Oncologic outcomes are at least equivalent to open approach. Minimally invasive approach for benign pathologies is widely applied. There are significant variations in VATS approaches for thymus, showing a multinational interest in the issue of minimizing trauma during thymectomy. Use of robotic technology is also popular, as the retrosternal area is a narrow anatomic space to manipulate conventional instruments. The evolution of minimally invasive surgery for thymus has been possible with contribution from centers all around the world. In the current practice, various approaches are being adopted and every surgeon should prefer a technique depending on surgical preference and experience.

AB - During the last two decades, there was a tremendous development of video-assisted thoracoscopic surgery (VATS), especially in the field of video-assisted lung resections.

The problems in practical application are illustrated as well as clinical results, like they are presented in literature. PMID- 29445595 TI - Anesthesia and analgesia: how does the role of anesthetists changes in the ERAS program for VATS lobectomy. AB - Enhanced recovery after surgery (ERAS) programs are developed to prevent factors that delay postoperative recovery as well as issues that cause complications. The development of video-assist thoracoscopic surgery (VATS) techniques favors the fast recovery after thoracic procedures. ERAS strategies are based on multidisciplinary approach in which the anesthetist plays an important role from the preoperative to the postoperative phase with several goals. After preoperative evaluation and medical optimization, the anesthetist must ensure a tailored anesthetic plan aiming to a fast recovery and adequate pain relief to reduce the response to the surgical stress. The present narrative review presents the major parts of the ERAS anesthetic approach to VATS lobectomy like short acting drugs, protective one-lung ventilation (OLV), fluid administration and opioid-sparing multimodal analgesia. PMID- 29445597 TI - The technique of VATS right pneumonectomy. AB - Pneumonectomy has higher morbidity and mortality rate than any other anatomic lung resection. It is infrequently performed by VATS and mostly in high volume centers. The handling of central vessels with long instruments across very small incisions instead of palpation is the main cause of surgeon's discomfort and resistance to perform this radical type of resection. Published data on VATS pneumonectomy is still limited and based on case series. Nevertheless, the available series suggest that VATS pneumonectomy is at least equivalent to open pneumonectomy. Through a case presentation illustrated with surgical videos, we aim to describe the main technical features of a uniportal VATS right pneumonectomy for lung cancer. The clinical indications, contraindications, patient's preoperative evaluation and postoperative care will also be discussed. PMID- 29445598 TI - Small incisions, major complications: video-assisted thoracoscopic surgery management of intraoperative complications. AB - The object of our study is to show the causes leading to conversion, in order to observe the responsible variables and analyses if conversion influences the patient's outcome. Between January 2013 and December 2016, Udine Thoracic Department performed 180 video-assisted thoracoscopic surgery (VATS) lobectomies, and 24 cases were converted to thoracotomy due to an intra-operative complication such as arterial or venous bleeding, airway and other injuries. The VATS lobectomies' number increased over the three years: from 27 in 2013 to 55 in 2015 and 48 in 2016. While conversion's rate decreased from 33% in 2013 to 5.5% in 2015 and 10% in 2016. We performed a univariate and a multivariate analysis looking for the variables affecting the conversion rate. This was significantly related to intraoperative bleeding and airway injuries (P<0,001). Seventy-year older patients were not associated to a higher conversion rate, instead they showed an increased risk of post-operative complications (P<0,018, RR =1.8). We have focused our attention on all the variables leading to conversion and conditioning the patient's outcome in terms of post-operative complications and length of stay. The best strategy to face VATS complication is to prevent them. Young surgeons at the beginning of their learning curve should perform VATS lobectomies under close supervision of a skilled VATS surgeon. Moreover, conversion to open thoracotomy should be not considered a failure of VATS, but rather a procedure for patient's safety.

PMID- 29445602 TI - Uniportal video-assisted thoracoscopic surgery (VATS) sleeve resections for non small cell lung cancer patients: an observational prospective study and technique analysis. AB - Bronchus sleeve resection for operative treatment of non-small cell lung cancer (NSCLC) is a gold standard in modern thoracic surgery in cases of centrally located tumors or hilar lymph node metastases. Advanced instruments and growing surgical experience allowed surgeons to reduce the required incisions (from 3 port to uniportal) and to resect larger and more centrally located malignancies minimal invasively. It is a logical and expected advance in thoracic surgery that video-assisted thoracoscopic surgery (VATS) would be ultimately used also for complex bronchial resections. We therefore present in this study our early clinical results and technique of uniportal sleeve resections for patients with centrally located NSCLC or carcinoids. In the period 2015-2017, n:40 patients with NSCLC were found eligible for uniportal VATS sleeve resection in our institution. In two cases a thoracotomy conversion because of severe hilar scar tissue was necessary. In 38 cases a uniportal VATS sleeve resection could be completed. We believe that uniportal sleeve resections are the logical evolution of VATS allowing patients with locally advanced malignancies to have quicker recovery and reduced perioperative pain. PMID- 29445601 TI - Predictors of unexpected nodal upstaging in patients with cT1-3N0 non-small cell lung cancer (NSCLC) submitted to thoracoscopic lobectomy. AB - Background: In the last decades, the use of video-assisted thoracoscopic surgery (VATS) lobectomy for the treatment of early stage non-small cell lung cancer is continuously growing. This is mainly due to the development of more advanced surgical devices, to the rising incidence of peripheral lung tumors and is also favored by the increased reliability of preoperative staging techniques. Despite this progress, postoperative unexpected nodal upstaging is still a relevant issue. Aim of this study is to identify possible predictors of unexpected nodal upstaging in patients affected by cT1-3N0 NSCLC submitted to VATS lobectomy. Methods: A total of 231 cases of cT1-3N0 patients submitted to thoracoscopic lobectomy at our centre between June 2012 and October 2016 were retrospectively reviewed. All data regarding clinical staging by means of computed tomography (CT) and positron-emission tomography (PET)/CT were collected and reviewed. The subsequent pathological staging has been analyzed, with special regards to the possible type of nodal involvement, and the number of pathological nodal stations. Results: Most of the patients included in this study were in a clinical stage cT1aN0, cT1bN0 (stage IA) and cT2aN0 (stage IB), 86 (37.2%) patients, 73 (31.6%) patients and 62 (26.8%) patients, respectively. Postoperative histopathological analysis showed that the most frequent tumor histotype was adenocarcinoma (192 patients, 83.1%). Thirty-eight (16.5%) patients had a nodal upstaging; among these, 17 (7.4%) patients had N2 disease (8 patients with isolated mediastinal nodal involvement, 9 patients with N1 + N2 disease) and 21 (9.1%) patients had an isolated hilar nodal involvement (N1). At bivariate analysis, the clinical T (cT)-parameter (P=0.023), the histotype (P=0.029) and the pathological T (pT)-parameter (P=0.003) were identified as statistically significant predictors of nodal upstaging. Concerning the type of nodal upstaging, the pT was found to be statistically significant (P=0.042). At bivariate analysis for the number of involved nodal stations, a statistical significance was highlighted for the parameters cT (P=0.030) and pT (P=0.027). With linear logistic regression, histology as well as pT reached statistical significance (P=0.0275 and P=0.0382, respectively). No correlation was found between nodal upstaging and the intensity of FDG uptake in the primary lung tumor or with the timing between PET and surgery. Conclusions: There is a strong correlation between the clinical staging of the parameter T evaluated with CT and the possible unexpected nodal upstaging. The same correlation with nodal upstaging is found for pT. At equal clinical stage, in patients affected by adenocarcinoma of the lung the relative risk of having a postoperative unexpected nodal upstaging is almost 7 times higher than in patients with squamous cell carcinoma. PMID- 29445603 TI - Uniportal video-assisted thoracic lung segmentectomy with near infrared/indocyanine green intersegmental plane identification. AB - In the era of lung cancer screening and early detection of lung lesions, pulmonary segmentectomy has gained wide acceptance between thoracic community reducing the need of lobectomy for diagnostic purpose and treatment in case of centrally located benign, multiple or undetermined lesions. In rigorously selected patients with stage I non-small cell lung cancer (NSCLC), segmentectomies seem to offer similar survival outcomes rather than lobectomies, but associated with a better conservation of lung function. However, segmentectomy is a more challenging procedure to be performed compared to lobectomy, especially by video-assisted thoracic surgery (VATS). Many difficulties could arise during video-assisted segmentectomy, making the procedure more demanding and stressful. Following the introduction of the near infrared (NIR)/indocyanine imaging system on standard endoscopic module, we decided to adopt peripheral intravenous injection of indocyanine green (ICG) to identify intersegmental plain during uniportal VATS lung segmentectomy. Our technique herein is widely illustrated. PMID- 29445604 TI - Uniportal non-intubated thoracic surgery. AB - Uniportal video-assisted thoracoscopic surgery (VATS) is the most advanced evolution of the minimally invasive technique, which allows often the possibility to include patients in enhanced recovery programs in order to optimize the therapeutic pathway, shorten the length of stay and reduce hospital costs. Non intubated VATS procedures allow the performance of surgeries with minimal sedation without general anesthesia, maintaining throughout the operation spontaneous breathing. The principle is to create an iatrogenic spontaneous pneumothorax, which can provide a good lung isolation without the need of a double lumen tube. A survey between the members of the European Society of Thoracic Surgery (ESTS) showed that non-intubated VATS procedures are already performed by a large number of ESTS members for minor procedures. With the publication of new data and the spreading of uniportal VATS in many centers worldwide in the last decades, the application of the non-intubated technique in major procedure like anatomic resections is expected to grow. This technique can potentially be beneficial for high-risk patients but also could be used for the routine procedures as well, but more data are needed to establish the real benefit for these groups of patients. PMID- 29445605 TI - The state of uniportal video-assisted thoracoscopic surgery in North America: a survey of thoracic surgeons. AB - Background: In recent years, there has been an exponential growth in the research and development of uniportal video-assisted thoracoscopic surgery (VATS). In the context of the 2017 Annual Asian Single-Port VATS Symposium held in Shanghai, China, we sought to describe current the state of uniportal VATS in North America and explore factors that could influence future adoption. Methods: In March 2017, a five-question survey was distributed to North American Thoracic Surgeons in order to obtain their opinion regarding the uniportal VATS approach to pulmonary resection. Responses were summarized and statistical comparisons of categorical variables were performed using Fisher's exact test. Results: The estimated response rate to the survey was 16.5% (99/600). The majority of respondents were experienced surgeons with 41.4% (41/99) having been in practice 11-20 years. The majority (70%; 69/99) of surgeons had never performed a uniportal VATS procedure. When surgeons were asked to state what could potentially convince them to adopt uniportal VATS, scientific evidence of superiority (86%; 85/99) and/or of superior ergonomics (39%; 39/99), attendance to focused conferences with a practical simulation component (38%; 38/99), and the availability of surgical proctorship (9%; 9/99) were the most commonly selected responses. Conclusions: This survey is the first of its kind to provide a glimpse into the status of the uniportal VATS in North America. The responses suggest that there are few early adopters of this approach as compared to other parts of the world. The lack of perceived advantages to uniportal VATS and the need for more comparative evidence to other established approaches appear to be major obstacles to more widespread adoption in North America.

AB - Background: Liver resection is a complex procedure for trainee surgeons. Cognitive task analysis (CTA) facilitates understanding and decomposing tasks that require a great proportion of mental activity from experts. Methods: Using CTA and video-based coaching to compare liver resection by open and laparoscopic approaches, we decomposed the task of liver resection into exposure (visual field building), adequate tension made at the working plane (which may change three dimensionally during the resection process), and target processing (intervention strategy) that can bridge the gap from the basic surgical principle. Results: The key steps of highly-specialized techniques, including hanging maneuvers and looping of extra-hepatic hepatic veins, were shown on video by open and laparoscopic approaches. Conclusions: Familiarization with laparoscopic anatomical orientation may help surgeons already skilled at open liver resection transit to perform laparoscopic liver resection smoothly. Facilities at hand (such as patient tolerability, advanced instruments, and trained teams of personnel) can influence surgical decision making. Application of the rationale and realizing the interplay between the surgical principles and the other paramedical factors may help surgeons in training to understand the mental abstractions of experienced surgeons, to choose the most appropriate surgical strategy effectively at will, and to minimize the gap.

AB - This video aimed to describe the role of intraoperative neuromonitoring (IONM) during transoral endoscopic thyroidectomy vestibular approach (TOETVA) with emphasis given to IONM technical and technological notes, the identification of recurrent laryngeal nerve (RLN). Standardized technique of IONM consist in identifying and monitoring both the vagus nerve and the RLNs before and after resection (V1, V2, R1, R2). According to this report, IONM during TOETVA is feasible and safe in providing identification and function of laryngeal nerves. IONM enable surgeons to feel more comfortable with their initial approach to TOETVA or extended indications. Larger series are needed for appropriated evaluation of IONM in reduction of the rates for RLN complications.

PMID- 29445612 TI - Application of the coaxial smart drain in patients with a large air leak following anatomic lung resection: a prospective multicenter phase II analysis of efficacy and safety. AB - Background: The presence of air leak following lung resection remains a frequent problem, which may prolong hospital stay and increase hospital costs. In the past, some studies documented the efficacy of soft and flexible chest tube in patients who underwent thoracic surgery. Nevertheless, safety in case of post operative large air or liquid leak remains questionable. The objective of this study was to verify through a multicentre study the safety and the effectiveness of the coaxial chest tube in a consecutive series of selected patients who underwent anatomical pulmonary resection and with an active and large air leak. Methods: Between October 2016 and September 2017, data from patients submitted to anatomical lung resection with curative intent and operated in two Department of Thoracic Surgery of two different were prospectively collected. The inclusion criteria consisted in the presence of an air leak greater than 50 mL/min measured with a digital drainage system during the 3 postoperative hours. A descriptive statistic was used to report the incidence of complications assumed to be associated with the use of the coaxial drain. Results: Forty-eight consecutive patients (27 males) submitted to lobectomy (37 patients: 77%) or anatomic segmentectomies (11 patients) were included in the analyses. Thirty-four operations (71%) were performed by video-assisted thoracic surgery (VATS). The median duration of chest tubes was 13 days [interquartile range (IQR), 4-19] and the median duration of air leak was 9 days (IQR, 2-17.5). No patient had undrained postoperative pleural effusion judged to require an additional chest tube placement. There were 12 (25%) cases of clinically or radiologically significant surgical emphysema; in none of these patients any additional procedure or re-operation was required, and they were treated conservatively by increasing the level of suction. Conclusions: Our experience with this novel Coaxial Drain was satisfactory with no clinically relevant complication caused using this drain, no need to insert additional drain or replace the existing one with another drain a duration of air leak and chest tubes as well as the incidence of subcutaneous emphysema that was in line with what observed in the daily practice in similar highly selected patients with large air leak.

AB - The aim of this study was to characterize serum protein capillary electrophoretic pattern in apparently healthy adult male (age: 3-7 years) dromedary camels and also evaluate total protein and albumin levels using automated analyzer. Blood samples were taken from 20 camels. 5ml of blood was collected from the jugular vein and serum was separated from samples by centrifugation. Capillary electrophoresis of serum proteins identified six protein fractions in adult camels, including albumin, alpha1, alpha2, beta1, beta2 and gamma globulins, serum levels of these parameters were 3.9+/-0.04 g/dl, 0.16+/-0.01 g/dl, 0.39+/ 0.03 g/dl, 0.515+/-0.03 g/dl, 0.205+/-0.01 g/dl and 0.61+/-0.04 g/dl, and 65.42+/ 0.62 g/l, respectively. The total protein concentration was 65.42+/-0.62 g/L, while, the albumin/globulin (A/G) ratio was 2.4+/-0.14. The present study indicates six peaks with minicapillary electrophoresis and the results obtained were compared and interpreted in the light of finding reported by other investigators in camels. PMID- 29445615 TI - Thermodynamic effects of commercially available ice boots. AB - The limb of the equine athlete is subjected to all types of various stressors during exercise. To ensure the health of the horse and to prevent the possibility of lameness, it has been a common practice to apply cold therapy to the distal limb of the horse pre- and post-exercise. Commercially available boots are widely available for the application of cold therapy. To test the effectiveness of the boot, 6 healthy performance level sport type horses were exercised at a walk, trot, and canter in a round-pen and then subjected to the application of the ice boot for 20 minutes on a treatment leg, and no ice boot on an untreated leg. Thermal images were taken of the 3rd metacarpal region pre-exercise, post exercise, post-ice boot, and every 2 minutes after until the difference between the temperatures of the control leg and the treatment leg became zero. The images were analyzed using an analysis software (FLIR Tools) to determine the average temperature of the 3rd metacarpal region at each time point. The measured temperatures between treatments were found to be significantly different due to the application of the ice boot, providing evidence that the boot sufficiently cools the leg (P<.01). Thereafter, a 95% confidence interval was created to depict the average time it took for the cooled leg to return to average temperature post-ice boot, suggesting that it takes about 14.67 minutes for the difference between the temperatures of the cooled leg versus the non-cooled leg to become zero. This finding is significant to horse owners, trainers, and veterinarians that use this commonly available tool. These findings lend evidence to support the common practice of using cold therapy in treatment of disease in the horse.

AB - We report clinical and pathological features of enzootic nasal adenocarcinoma (ENA) in one sheep in Algeria. A one-year-old Ouled Djellal sheep from a large herd (~1240 animals), located in Bordj Bou Arreridj, Algeria, was clinically diagnosed by the presence of persistent seromucous nasal discharge, head shaking, muzzle licking, dyspnoea, exophthalmia and frontal protrusion. The sheep was euthanized, and the necropsy was performed. Gross examination showed soft touch, pinkish-white tumour masses in the nasal cavities with distortion of the turbinates and of the medium septum. According to clinical and pathological findings, the tumour has been defined as a low grade mixed nasal adenocarcinoma, with the presence of tubular and papillary structures. This is, to our knowledge, the first report of ENA in Algeria known to be associated with enzootic nasal tumour virus (ENTV) infection. However, such association requires confirmation by direct and/or indirect viral investigation.

AB - Dermatophilosis is one of the major economically important diseases of cattle in Nigeria. Managing the condition has been very challenging and re-occurrence has been reported with moderate to high morbidity and mortality. The incidence and biochemical features of cattle with dermatophilosis was conducted in June to December 2016 across the four geopolitical zones of Oyo state, Nigeria. Clinical diagnosis were made based on appearance of dermatophilosis lesion, breeds morphologically characterized, ageing were based on rostral dentition and severity based on the extent and nature of the lesion. Biochemical analysis was based on standard procedure as prescribed by Fortress International. Fifty cattle were found to be infected with clinical dermatophilosis during the period of the study. Twenty four (48%) in Ibadan zone, 14 (28%) in Oyo/Ogbomosho, 8 (16%) in Oke-ogun and 4 (8%) in Ibarapa zone. Breeds distribution across the zones showed 28 (56%) White Fulani, 5 (10%) Sokoto Gudali, 3 (6%) Adamawa Gudali, 7 (14%) Red Bororo, 5 (10%) Cross breeds while the Kuri was 2 (4%). Regarding animal ages, less than 2 years old were 2 animals (4%) while the adults were 48 animals (96%) and they fall under the categories of 2-21/2 years of age, 3-31/2 years of age and those which are over 31/2 years of age. The different levels of severity were categorized into mild (20 (40%)), moderate (23 (46%)) and severe (7 (14%)) .The best parameters were seen in White Fulani, while the least were seen in Adamawa Gudali. The age group in the category of 3 - 31/2 years had most of the best serum values while the least values were seen in animals less than 2 years of age. Cattle exhibiting mild lesions had most of the best serum values and the least values were observed in cattle with severe lesions. No significant difference (p > 0.05) was observed in the mean values for the various parameters studied among the breeds, age, and severity of condition. PMID- 29445617 TI - Pathogenic Leptospira: Advances in understanding the molecular pathogenesis and virulence. AB - Leptospirosis is a common zoonotic disease has emerged as a major public health problem, with developing countries bearing disproportionate burdens. Although the diverse range of clinical manifestations of the leptospirosis in humans is widely documented, the mechanisms through which the pathogen causes disease remain undetermined. In addition, leptospirosis is a much-neglected life-threatening disease although it is one of the most important zoonoses occurring in a diverse range of epidemiological distribution. Recent advances in molecular profiling of pathogenic species of the genus Leptospira have improved our understanding of the evolutionary factors that determine virulence and mechanisms that the bacteria employ to survive. However, a major impediment to the formulation of intervention strategies has been the limited understanding of the disease determinants. Consequently, the association of the biological mechanisms to the pathogenesis of Leptospira, as well as the functions of numerous essential virulence factors still remain implicit. This review examines recent advances in genetic screening technologies, the underlying microbiological processes, the virulence factors and associated molecular mechanisms driving pathogenesis of Leptospira species.

Comparative oncology as an integrative approach offers to learn more about naturally occurring cancers across different species. Canine models have many advantages as they experience spontaneous disease, have many genes similar to human genes, five to seven-fold accelerated ageing compared to humans, respond to treatments similarly as humans do and health care levels second only to humans. Also, the clinical trials in canines could generate more robust data, as their spontaneous nature mimics real-life situations and could be translated to humans. PMID- 29445620 TI - Genetic analysis of maternal and paternal lineages in Kabardian horses by uniparental molecular markers. AB - Studies of mitochondrial DNA (mtDNA) as well as the non-recombining part of the Y chromosome help to understand the origin and distribution of maternal and paternal lineages. The Kabardian horse from Northern Caucasia which is well-known for strength, stamina and endurance in distance riding has a large gap in its breeding documentation especially in the recent past. A 309 bp fragment of the mitochondrial D-loop (156 Kabardian horses) and six mutations in Y chromosome (49 Kabardian stallions), respectively, were analyzed to get a better insight into breeding history, phylogenetic relationship to related breeds, maternal and paternal diversity and genetic structure. We found a high mitochondrial diversity represented by 64 D-loop haplotypes out of 14 haplogroups. The most frequent haplogroups were G (19.5%), L (12.3%), Q (11.7%), and B (11.0%). Although these four haplogroups are also frequently found in Asian riding horses (e.g. Buryat, Kirghiz, Mongolian, Transbaikalian, Tuvinian) the percentage of the particular haplogroups varies sometimes remarkable. In contrast, the obtained haplogroup pattern from Kabardian horse was more similar to that of breeds reared in the Middle East. No specific haplotype cluster was observed in the phylogenetic tree for Kabardian horses. On Kabardian Y chromosome, two mutations were found leading to three haplotypes with a percentage of 36.7% (haplotype HT1), 38.8% (haplotype HT2) and 24.5% (haplotype HT3), respectively. The high mitochondrial and also remarkable paternal diversity of the Kabardian horse is caused by its long history with a widely spread maternal origin and the introduction of Arabian as well as Thoroughbred influenced stallions for improvement. This high genetic diversity provides a good situation for the ongoing breed development and performance selection as well as avoiding inbreeding. PMID- 29445621 TI - Immunohistochemical evaluation of lymphocyte populations in the nictitans glands of normal dogs and dogs with keratoconjunctivitis sicca. AB - Idiopathic canine keratoconjunctivitis sicca (iKCS) is a common condition of the canine eye involving a deficiency in aqueous tear production which is commonly held to have an immune-mediated, as most probably an autoimmune aetiopathogenesis. Yet to date no direct evaluation has been made of the inflammatory cell populations in the lacrimal tissue of dogs with iKCS. Here we sought to quantify T and B lymphocyte populations in the lacrimal tissue of the nictitans glands of dogs with iKCS those with neurological KCS (nKCS)and also in dogs with tear production within the recognized normal levels and no ocular surface signs of KCS. Nictitans glands were obtained from 10 healthy dogs with no signs or history consistent with KCS at post-mortem or after enucleation. Nictitans glands were also obtained at parotid duct transposition surgery from ten dogs with idiopathic KCS and three with neurogenic KCS. Histological sections form the lacrimal tissue were processed immunohistochemically with primary monoclonal antibodies recognizing the T lymphocyte CD3 antigen and the B lymphocyte CD79a antigen. Cell numbers were counted in 10 randomly sampled representative high-power fields in five sections. Statistical significance of differences in cell numbers was determined using analysis of variance with significance achieved at p=0.05.Nictitans glands from dogs with iKCS showed elevated numbers of T and B lymphocytes compared with those from dogs with normal tear production. The increase in the T cell population was highly statistically significant (p=0.0025) while the increase in B cells, while statistically significant was less pronouncedly so (p=0.049). T and B lymphocyte numbers were not significantly elevated in nictitans glands from dogs with neurogenic KCS compared with those in dogs with normal tear production. The elevation in the T cell population seen in dogs with idiopathic KCS strongly supports the widely held assumption that this disease is an immune-mediated and probably autoimmune. The lack of increase in T cell populations in dogs with nKCS strongly suggests that the changes in iKCS are causing the tear deficiency and not resulting from it. PMID- 29445622 TI - Palmar annular ligament desmotomy in horses with the Arthrex-CenterlineTM : An ex vivo study. AB - The aim of this study was to evaluate the use of a single-portal endoscopic desmotomy of the PAL with the use of Arthrex - CenterlineTM. Ten horse distal front limbs from horses free of PAL disease were prepared for tenoscopy of the digital flexor tendon sheath (DFTS). A dual-port endoscopic desmotomy with a hook knife was performed in 5 specimens (Group A) and single port Arthrex-CenterlineTM Desmotomy was performed in another 5 specimens (Group B). The performing time, judgments of the surgeon, number of blade passages, and gross anatomy were evaluated. The performing time and surgeon judgments were significantly lower in Group B. No significant differences were assessed in number of passages to achieve a complete PAL resection and a gross anatomy evaluation. The use of Arthrex-CenterlineTM is feasible for a PAL desmotomy procedure. It was faster with more handling ease compared with the free-hand double-portal desmotomy and allowed the same results in terms of number of passages to complete the release evaluated at gross anatomy.

PMID- 29445624 TI - Dioxin Exposure in the Manufacture of Pesticide Production as a Risk Factor for Death from Prostate Cancer: A Meta-analysis. AB - Background: In pesticide exposure groups such as farmers, the risk of prostate cancer was increased, although the report of the cause of evidence is limited. We selected chlorophenol compounds as an important group of the contaminated pesticide with highly toxic 2, 3, 7, 8-tetrachlorodibenzo-p-dioxin (TCDD). This meta-analysis, the risk of death from prostate cancer was analyzed. Methods: PubMed, Scopus, Scholar Google and web of Sciences until 2016 were searched. The standardized mortality rate (SMR) and 95% confidence intervals (CI) were obtained from the studies. We tested statistical heterogeneity with Cochrane Q test and I2 index. Egger test was used for evaluating publication bias. Random or fixed effects models and meta-regression were also used in our analysis. Moreover, Cochrane tool was used to assess the risk of bias. Results: Five available papers consist of 28706 exposed populations were assessed. Overall standardized mortality rate as combined result of prostate cancer risk from the fixed model was 1.2 (95% confidence interval (CI) 1.02 to 1.42, P=0.027). Some biases are more probable in these studies such as confounding by indication, loss to follow up and misclassification. Conclusion: A contaminated pesticide with dioxins between other pesticides is an important risk factor for prostate cancers. PMID- 29445625 TI - Improvement of Emergency Management Mechanism of Public Health Crisis in Rural China: A Review Article. AB - Background: With the rapid development of social economy in China, various public health emergencies frequently occur. Such emergencies cause a serious threat to human health and public safety, especially in rural China. Owing to flaws in emergency management mechanism and policy, the government is not capable to effectively deal with public health emergencies. Therefore, this study aimed to discuss the path to improve the emergency management mechanism for public health emergency in rural China. Methods: This study was conducted in 2017 to detect the emergency management mechanism of public health crisis (EMMPHC) in Rural China. Data were collected using the following keywords: Rural China, public health emergency, emergency management mechanism, organization mechanism, operation mechanism in the databases of PubMed, Scopus, Web of Science, and CNKI. Results: EMMPHC in rural China can be enhanced from the following three aspects. First, a permanent institution for rural emergency management with public health management function is established. Second, the entire process of emergency management mechanism, including the stages of pre-disaster, disaster, and post disaster, is improved. Finally, investment in rural public health is increased, and an adequate reserve system for emergency resources is formed. Conclusion: The new path of EMMPHC in rural China can effectively help the local government accomplish the dispatch capability in public health emergency, and it has important research significance for the protection of public health and social stability of residents in rural China. PMID- 29445626 TI - Catastrophic Health Expenditure in Iran: A Review Article. AB - Background: One of the main challenges of healthcare systems is to protect people from consequences of health expenditures. Such expenditures may lead to catastrophic financial loss in families so that many people deny demanding necessary healthcare services, which results in harms to their health status. The aim of this systematic review was to investigate the catastrophic health expenditures trend and its related factors in Iran. Methods: This systematic review and meta-analysis was conducted on studies conducted between 1984 and 2014. Data were collected through searching electronic databases and searching engines of PubMed, Scopus, EconLit, Google Scholar, Science Direct, MagIran, and Scientific Information Database (SID). The random effects were used with 95% confidence interval for the meta-analysis. Results: Out of 561 initially retrieved articles, finally 42 were included in the final analysis. The studies were conducted between 1984 and 2014. The overall proportion of exposure to catastrophic health expenditure in Iran was 7.5% (95% CI, 6.2 - 9.1). In the urban and rural areas, the proportion was 2.3% (95% CI, 1.8 - 2.9) and 3.4% (95% CI, 2.8 - 4.1) respectively. The overall proportion of exposure to the catastrophic health expenditure in hospitals was 35.9% (95% CI, 23.5 - 54.3). Conclusion: The catastrophic expenditures proportion of healthcare is relatively high in Iran and the government is expected to adopt effective measures in this regard, especially for the inpatient care. There are needs for special supporting policies for the financial protection of specific patients, the poor and villagers.

Ancient physicians declared some of the confirmed pharmacological effects. Conclusion: Maidenhair fern frond can be a good candidate for clinical purpose. Therefore, future researches on the other mentioned effects in traditional medicine are recommended. PMID- 29445629 TI - Trends and Associated Factors of Hypertension among Residents Aged >=15 Years in Guangzhou, China, 2004-2013. AB - Background: We aimed to describe the trends and associated factors of hypertension among residents aged >=15 yr in Guangzhou, China. Methods: Three standardized cross-sectional health surveys were conducted in 2004, 2009 and 2013 using a multi-stage cluster sampling method, and a total of 69128 qualified participants were included in the study. The data were obtained through physical health examination and questionnaire survey. Results: The age-standardised prevalence of hypertension increased from 12.5% to 16.0% between 2004 and 2009 and declined from 16.0% to 14.0% between 2009 and 2013, and crude prevalence respectively was 14.6%, 19.1% and 18.8% in 2004, 2009 and 2013. The proportion of optimal blood pressure dropped from 51.1% to 33.2%, high-normal blood pressure increased from 20.1% to 28.9%, grade 1 hypertension and grade 2 or 3 hypertension increased from 11.5% to 13.6% and 3.9% to 5.8% between 2004 and 2013. The average age was significantly increased (P<0.001) from 42.8 to 47.5 yr, and the average body mass index slightly increased (P<0.001) from 22.4 to 23.0. Logistic regression analysis shows that higher age, male, higher body mass index, smoking and drinking alcohol were potential risk factors for hypertension. Conclusion: Both crude and age-standardized prevalence of hypertension were initially increased, but subsequently decreased in Guangzhou during 2004-2013. The optimal blood pressure population decreased significantly while the high-normal blood pressure population increased substantially during the survey period. PMID- 29445631 TI - Effects of Negative Emotions and Life Events on Women's Missed Miscarriage. AB - Background: To investigate the effects of negative emotions and life events on women's missed miscarriage. Methods: Overall, 214 women diagnosed with a missed miscarriage by prenatal examination from 2016-2017 in Xiamen Maternal and Child Health Care Hospital, Xiamen, China were selected as the observation group compared to 214 women as control group. The general data of the patients were investigated by self-programmed questionnaires. Zung Self-Rating Anxiety Scale, Center Epidemiological Studies Depression Scale; Life Events Scale for Pregnant Women were used conduct the study. General data, anxiety, depression and life events were compared between the two groups of patients, and statistically different factors were included in the multivariate Logistic regression analysis. Results: There were statistically significant differences in the educational level, pre-pregnancy health status, planned pregnancy, pre-pregnancy or gestational gynecological inflammation and the initiative to obtain knowledge of prenatal and postnatal care between the two groups of pregnant women (P<0.01); there were also statistically significant differences in score of life events, score of anxiety and score of depression between them (P<0.01). The high educational level, good health status before pregnancy and the initiative to obtain the knowledge of prenatal and postnatal care were taken as the independent protective factors for the missed miscarriage in pregnant women, while life events, anxiety and depression were independent risk factors for it. Conclusion: Negative emotions and life events increase the risk of women's missed miscarriage, and the high educational level, good health status before pregnancy and the initiative to obtain the knowledge of prenatal and postnatal care reduce the risk of women's missed miscarriage.

Results: The visiting rates to medical institutions were 39.7%. The percentage who received a prescription for a diabetes mellitus medication from a doctor was 80.9%, the medication possession ratio was 70.8%, and the rate of medication adherence was 57.8%. Conclusion: The visiting rate, medication possession ratio and rate of medication adherence for DM medication were not high. In order to increase the visiting rate, medication possession ratio and rate of medication adherence, NHIS should support environment in which medical institutions and DM patients can do the role of each part. PMID- 29445632 TI - Trend of Medical Tourism Publications: An Attempt to Explore the Involved Academic Disciplines and Interests. AB - Background: Medical tourism suffers from the lack of a consensus regarding the involved categories. This study aimed to address this gap from the academic disciplines and publications perspective. Methods: Totally 1954 citations were identified through a formula of keyword search of SCOPUS. In order to classify the various subject areas, we followed the international standard classification of education (ISCED) developed by UNESCO. Moreover, the trends of publications were identified based on their popularity between 2000 and 2017. Results: The category with the most interests on publication about medical tourism was 'health and welfare', followed by 'social science'. Even though various disciplines were involved in the medical tourism, it seems that a downward trend has been experienced since 2015. Conclusion: The identified key trends of medical tourism publications will benefit researchers exploring the categories of medical tourism or health travel. The results contribute to advance the state of knowledge from the academic perspective. PMID- 29445633 TI - The Effect of Intensive Statin Therapy on Symptomatic Intracranial Arterial Stenosis. AB - Background: The aim of this study was to observe the effect of intensive statin therapy on symptomatic intracranial arterial stenosis. Methods: overall, 120 patients with symptomatic intracranial arterial stenosis were admitted to the Xiangyang No.1 People's Hospital, Hubei University of Medicine, Xiangyang, China from January 2010 to May 2013. They were randomly divided into three groups and were given different doses of atorvastatin orally for 1 year or more, and followed up for 12 months. The three groups were assessed for clinical end-point event rates and changes in cerebral blood flow value before and after treatment to assess the effectiveness of intensive statin therapy. Results: The incidence rates of end-point cerebrovascular events in the low-dose group (10 mg/d), the general-dose group (20 mg/d) and the intensive treatment group (40 mg/d) were 26.3%, 13.5% and 5.4% respectively during the 12-month follow-up after treatment. There was a significant difference between the low dose group and the intensive treatment group (P<0.05). The relative cerebral blood flow and relative cerebral blood volume of the three groups were significantly higher than those before treatment (P<0.05), and the relative time to peak for the intensive treatment group was shorter than that before treatment (P<0.001). Conclusion: Atorvastatin at 40 mg/d has a significant advantage compared with atorvastatin at 20 mg/d and 10 mg/d in reducing cerebrovascular events and improving cerebral blood flow. PMID- 29445635 TI - Implementing Health Impact Assessment at National Level: An Experience in Iran. AB - Background: According to the general health policies issued in 2014, Health Impact Assessment (HIA) or Health Annex should be implemented in Iran. The present study provided a model for executing HIA in the Iranian context as a developing country. Methods: This is a system design study with the qualitative approach. The data on the system components were gathered via reviews of the literature, in-depth interviews and focused group discussions (FGDs) with experts. The information were contently analyzed in order to draft the model and a consensus was reached on by the steering committee. Results: Fifteen in-depth interviews and six FGD meeting were conducted. The equity-based approach in assessing the health impacts of policies, programs and projects were chosen as the most practical tool. Experts believe that for the next five years, HIA should be used just for the "national projects" so that the ministries and national agencies could be empowered. Components of the model including structure, procedures, and standards, management style, mission and resources were prepared. The national regulations and protocols were sent to the SCHFS Secretariat for final revision and the council approval. Conclusion: The hasty implementation of HIA will face serious resistances as the health-oriented attitude and behavior in both government and non-governmental sectors will gradually form. Also, the overlapping of the contents of HIA with other tools such as Environmental, Cultural and Social Impact Assessments, currently used by other sectors, causes difficulties in implementing the HIA by the Ministry of Health and Medical Education. PMID- 29445634 TI - Evaluation of Respiratory Symptoms among Workers in an Automobile Manufacturing Factory, Iran. AB - Background: This study estimated the prevalence of respiratory symptoms and disorders among workers exposed to exposure to volatile organic compound (VOCs) in an automobile manufacturing factory in Tehran, Iran in 2016. Methods: Subjects of this case-control research were included 80 samples including 40 workers exposed to different level of BTEX as well as 40 unexposed individuals were considered as control group. Methods 1501 and 7602 presented by the National Institute of Occupational Safety and Health (NIOSH) were used for the sampling and analysis of compounds in the air. Gas Chromatography-Flame Ionization Detector (GC-FID) was used for analysis of compounds of interest. Six silica samples were collected during the campaign. Silica analyses were performed by using visible absorption spectrophotometry system. Lung functions were evaluated for 80 workers (40 exposed, 40 nonexposed) using spirometry system. Results: The average amount of total dust and free silica measured in factory were 7.3+/-1.04 mg.m-3 and 0.017+/-0.02 mg.m-3 respectively. Average benzene, toluene, ethyl benzene and xylene exposure levels in exposed subject's median were 0.775+/-0.12, 1.2+/-2.08, 45.8+/-8.5, and 42.5+/-23.9 ppm respectively. Statistical tests showed significant difference between pulmonary function tests (except PEF) of exposed and non-exposed individuals before and after employment (P<0.05). Workers exposed to VOCs presented lower levels of FVC, VC, and PEF than the control group except FEV1/FVC%, FEV1, FEF2575 and FEV1/VC%. Conclusion: Decline in lung volumes and respiratory symptoms, significant difference associated with the exposure to dust or gas, duration of exposure, and smoking habit. Therefore, lung function tests should be performed before and after the employment to identify sensitive workers candidates.

AB - Background: Asthma is the first cause of children hospitalization and need for emergency and impose high economic burden on the families and governments. We aimed to investigate the economic burden of pediatric asthma and its contribution to family health budget in Iran. Methods: Overall, 283 pediatric asthmatic patients, who referred to two tertiary pediatric referral centers in Tehran capital of Iran, included from 2010-2012. Direct and indirect asthma-related costs were recorded during one-year period. Data were statistically analyzed for finding association between the costs and factors that affect this cost (demographic variables, tobacco smoke exposure, control status of asthma and asthma concomitant diseases). Results: Ninety-two (32.5%) females and 191(67.5%) males with the age range of 1-16 yr old were included. We found the annual total pediatrics asthma related costs were 367.97+/-23.06 USD. The highest cost belonged to the medications (69%) and the lowest one to the emergency (2%). We noticed a significant increasing in boys' total costs (P=0.011), and 7-11 yr old age group (P=0.018). In addition, we found significant association between total asthma costs and asthma control status (P=0.011). Conclusion: The presence of an asthmatic child can consume nearly half of the health budget of a family. Our results emphasis on improving asthma management programs, which leads to successful control status of the disease and reduction in economic burden of pediatric asthma. PMID- 29445637 TI - Virulence Determinants and Antimicrobial Resistance Patterns of Vancomycin resistant Enterococcus faecium Isolated from Different Sources in Southwest Iran. AB - Background: This study aimed to investigate the incidence of antibiotic resistance and virulence genes in vancomycin-resistant Enterococcus faecium isolated from different sources in southwest Iran from Mar to Sep 2015. Methods: Overall, 120 E. faecium isolates (80 VRE and 40 vancomycin-susceptible enterococci [VSE] isolates) were obtained from four hospitals. The resistance of the VRE isolates was determined by disk diffusion method. Multiplex PCR was performed to detect the virulence genes carried by the E. faecium isolates, namely, enterococcal surface protein (esp), hyaluronidase (hyl), and collagen binding adhesin (acm). Results: All the VRE isolates exhibited multidrug resistance, with the rates of resistance to ampicillin, erythromycin, and ciprofloxacin reaching high levels. The isolates were least resistant to chloramphenicol and nitrofurantoin, but all of them were susceptible to linezolid. 46.6%, 20.8%, and 86.6% of the E.faecium isolates carried the esp, hyl, and acm genes, respectively. Conclusion: There is a significant difference between the prevalence of esp and hyl genes in the VRE and VSE isolates. In the VRE isolates, the high prevalence of multidrug resistance were found and the difference in the prevalence of esp among various sources was significant. The findings reflected a relationship between the prevalence of esp and hyl and resistance to certain antibiotics.

Data for 193 children, admitted in 2012-2013, were collected retrospectively. They were allocated to two groups of 2nd and 3rd trimester, based on the time of diagnosis antenatal hydronephrosis. Data analysis was done using SPSS. Chi-Square, Fisher-exact and independent t-test also Mantel-Hanzel test were used. P-value<0.05 was considered as statistically significant. Results: Of 193 infants (36 female, 157male), the antenatal hydronephrosis of 76 cases (39.4%) have been diagnosed in the 2nd trimester. In addition, 110 cases (57%) were bilateral and 33 cases (17.1%) had severe antenatal hydronephrosis. Consanguinity marriage, being unilateral or bilateral and the severity of antenatal hydronephrosis were significant with the specific trimester that it has been diagnosed (P<0.05). Conclusion: Infants with bilateral and severe grade of antenatal hydronephrosis also with the history of consanguinity marriage among their parent will diagnose in the second trimester more than the third trimester and will refer for some surgical correction, relating to other kidney diseases such as vesicoureteral reflux, more than others. Thus, this is a good sign for caring infants. PMID- 29445639 TI - The Association between Adverse Events in the Last 5 Years and the Rate of Breast Cancer. AB - Background: This study was conducted in Yazd Province, Central Iran aimed to investigate the relationship between adverse events and breast cancer during 2012 2014. Methods: Hospital-based case-control study of 150 women with breast cancer and 150 healthy women (did not have breast cancer) was conducted. Sampling was performed in the form of accessibility. Data collection was conducted using questionnaire through interview. The collected data were entered into SPSS for statistical analysis. Results: The mean age of participants was 51.58 yr. Eight percent of cases and 1.3% of the controls had experienced the sister's death over the past 5 yr, this difference was statistically significant (P=0.03). Factors such as disability due to illness, divorce, unemployment, the second marriage, addiction, ill spouse, child's problems (such as conflict, unemployment, addiction, legal troubles, illness), taking care of their own parents or their husband's parents, migration, change of habitat, loss of home, communication problems, job-relevant factors were not significantly different between the two groups (P>0.05). Mean of severity of adverse events in both groups was significantly different (8.92+/-8.29 in the case group, 5.72+/-5.6 in the control group) (P=0.000). Conclusion: There was no significant relationship between adverse events in the last 5 yr and the risk of breast cancer. Factors such as personality and ability to cope with problems may positively influence this relationship. PMID- 29445640 TI - Medical Waste Management in Community Health Centers. AB - Background: Non-standard management of medical waste leads to irreparable side effects. This issue is of double importance in health care centers in a city which are the most extensive system for providing Primary Health Care (PHC) across Iran cities. This study investigated the medical waste management standards observation in Tabriz community health care centers, northwestern Iran. Methods: In this triangulated cross-sectional study (qualitative-quantitative), data collecting tool was a valid checklist of waste management process developed based on Iranian medical waste management standards. The data were collected in 2015 through process observation and interviews with the health center's staff. Results: The average rate of waste management standards observance in Tabriz community health centers, Tabriz, Iran was 29.8%. This case was 22.8% in dimension of management and training, 27.3% in separating and collecting, 31.2% in transport and temporary storage, and 42.9% in sterilization and disposal. Lack of principal separation of wastes, inappropriate collecting and disposal cycle of waste and disregarding safety tips (fertilizer device performance monitoring, microbial cultures and so on) were among the observed defects in health care centers supported by quantitative data. Conclusion: Medical waste management was not in a desirable situation in Tabriz community health centers. The expansion of community health centers in different regions and non-observance of standards could predispose to incidence the risks resulted from medical wastes. So it is necessary to adopt appropriate policies to promote waste management situation.

AB - : Background: Bariatric surgery with the improvement of obesity-related diseases, increases longevity and quality of life and is more cost-effective when compared to non-surgical Procedures. Objective: The aim of this study is to compare the cost-effectiveness of Laparoscopic Sleeve Gastrectomy (LSG) and Laparoscopic Roux en-Y Gastric Bypass (LRYGB). METHOD: This study was performed in two stages. Initially, a cross-sectional study was carried out for costing LSG and LRYGB in Rasoul Akram and Bahman hospitals in Tehran in the year 2014. Direct costs for each surgical procedure were calculated according to the average time of surgery in both the private and public sectors. In the second stage, using Outcome (DeltaBMI) collected by means of a systematic review study and cost data; cost effectiveness of two surgical procedures was examined by ICER analysis and compared with threshold limit. The Perspective of this analysis was health system. Results: The direct cost of services for LRYGB was $ 2991.5 (98121659 Rials) in the public sector and $4221.9 in the private sector. In LSG, it was $ 1952.9 (64055468 R) in the public sector and $ 3177.2 in the private sector. ICER for LSG was 720.48(23631855 R) and $716.27 (23493924 R) in private and public sector respectively. Conclusion: In this study, LSG procedure when compared to LRYGB was cost effective. The ICER obtained indicated that LSG surgery in comparison to LRYGB was $716.27 (23493924 R) and $720.48(23631855 R) in the public and private sector respectively. Moreover, per unit change in BMI was less than the threshold. PMID- 29445650 TI - The relationship between social capital components and control of type 2 diabetes: A path analysis model. AB - Background: Social capital is an important interpersonal organizational resource that may affect health behaviors and seems to be an important factor in chronic diseases. Considering the lack of evidence on this topic, in the present study, we aimed at investigating the association between components of social capital, socioeconomic condition, and controlling Type 2 diabetes mellitus in Iran. Methods: This study was conducted on 300 patients with Type 2 diabetes in Tehran, Iran. In this study, simple random sampling method was used for data collection. Path analysis model was used to examine the potential association between social capital components and to determine the factors that control Type 2 diabetes. Results: In the present study, most of the participants were female (70.7%) and married (78.7%). Path coefficients were calculated by a series of multiple regression analyses based on the conceptual model. The final model had a proper fit with Chi-square = 2.08 (DF = 1, P = 0.049), GFI = 0.542, AGFI = 0.915, NFI = 0.228, RFI = 0.284, IFI = 0.299, TLI = 0.292, CFI = 0.219, and RMSEA = 0.033. The Groups and networks (network) (beta = 0.051, p = 0.036) and trust and solidarity (beta = -0.018, p = 0.028) had a direct positive and negative effect on HbA1C, respectively. The results also revealed that education levels had a direct positive effect on groups and networks (network) (beta = 0.118, p = 0.036), trust and solidarity (beta = 0.082, p = 0.007), information and communication (beta = 0.037, p = 0.027), and contribution in team works and public activities (beta = 0.064, p = 0.003). In addition, education levels had an indirect positive effect on HbA1C through their effect on groups and networks (network), trust and solidarity, and information and communication. Conclusion: Social capital has a significant relationship with diabetes. Although it was not specified clearly which components of social capital were associated with diabetes, trust and solidarity showed a negative direct effect on HbA1C, respectively. Therefore, developing and implementing local and collective programs to build trust and increase the standards of social trust in patients with diabetes can be effective in controlling HbA1C. PMID- 29445652 TI - Pattern of some risk factors of cardiovascular diseases and liver enzymes among Iranian seafarers. AB - Background: Little information is available on the trend in cardiovascular risk factors and hepatic enzymes in Iranian seafarers. The present study aimed at assessing the pattern of obesity, hypertension, diabetes, elevated serum glutamic oxaloacetate transaminase (SGOT), and serum glutamate pyruvate transaminase (SGPT) in Iranian seafarers during 2010 to 2014. Methods: Data on cardiovascular risk factors and hepatic enzymes were extracted from seafarers' annual health examination of National Iranian Tanker Company (NITC) of 2010, 2012, and 2014. The repeated measure ANOVA was used to compare continuous variables across 3 years. Categorical data were analyzed using Chi-square test. Over weight was defined as BMI (Body Mass Index) >25 kg/m2; obesity was defined as BMI>=30 kg/m2; hypertension was defined as systolic blood pressure (SBP)> 140 mmHg, and diastolic blood pressure (DBP)> 90 mmHg, or a history of antihypertensive drug use. Diabetes (DM) was defined as fasting blood sugar (FBS) > 110 mg/dl, or having a history of oral hypoglycemic agents; and elevated SGOT and SGPT were defined as SGOT > 40 U/L and SGPT > 40 U/L, respectively. Results: The BMI mean+/ SD values of Iranian seafarers were 24.81+/-3.07 kg/m2, 25.51+/-2.96 kg/m2, and 25.96 +/- 3.02 kg/m2 in 2010, 2012, and 2014, respectively. A significant difference was observed in BMI over the study period. The mean of systolic and diastolic blood pressure did not significantly increase over time. The SGOT and SGPT means were not significantly different from 2010 to 2014. The prevalence of overweight increased significantly from 46.7% to 60.9% over the study period; however, the prevalence of obesity, hypertension, elevated SGOT, and elevated SGPT did not change significantly. Conclusion: The current survey showed that the obesity problem has increased among Iranian seafarers working on tankers, which is a concerning problem because obesity has negative effects on seafarers' health. PMID- 29445653 TI - Elements of healthy death: a thematic analysis. AB - Background: Death is a natural and frightening phenomenon, which is inevitable. Previous studies on death, which presented a negative and tedious image of this process, are now being revised and directed towards acceptable death and good death. One of the proposed terms about death and dying is "healthy death", which encourages dealing with death positively and leading a lively and happy life until the last moment. This study aimed to explain the views of Iranians about the elements of healthy death. Methods: This qualitative study was conducted for 12 months in two general hospitals in Tehran (capital of Iran), using the thematic analysis method. After conducting 23 in-depth interviews with 21 participants, transcription of content, and data immersion and analysis, themes, as the smallest meaningful units were extracted, encoded and classified. Results: One main category of healthy death with 10 subthemes, including dying at the right time, dying without hassle, dying without cost, dying without dependency and control, peaceful death, not having difficulty at dying, not dying alone and dying at home, inspired death, preplanned death, and presence of a clergyman or a priest, were extracted as the elements of healthy death from the perspective of the participants in this study. Conclusion: The study findings well explained the elements of healthy death. Paying attention to the conditions and factors causing healthy death by professionals and providing and facilitating quality services for patients in the end stage of life make it possible for patients to experience a healthy death. PMID- 29445654 TI - Subgroup dairy products consumption on the risk of stroke and CHD: A systematic review and meta-analysis. AB - Background: There is no global consensus about the relationship between dairy consumption and cardiovascular diseases (CVD). This study aimed at integrating the results of several studies to predict the dairy effects on CVD, e.g. stroke and CHD. Methods: In the present study, some major databases such as Scopus, Science Direct, and PubMed were searched up to September 2014. All prospective cohort studies dealing with dairy products consumption and CVD were surveyed regardless of their publication date or language. This reference population includes all individuals without any delimitation with regard to age, gender, or race. The quality of the study was evaluated using STROBE Checklist. Study selection and data extraction were done by 2 independent researchers separately. The indices in this study were RR and HR. The random model was used to combine the results. Results: Out of 6234 articles, 11 were included in the meta analysis. No relationship was found between stroke and consumption of milk, cream, and butter, and the results are as follow: RR = 0.91 (95%CI: 0.81-1.01) for milk, RR = 0.97 (95%CI: 0.88-1.06) for cream, and RR = 0.95 (95%CI: 0.85 1.07) for butter. However, cheese was found to decrease stroke risk: RR = 0.93 (95%CI: 0.88-0.99). The relationship of CHD with consumption of milk, cheese, cream, and butter are as follows, respectively: RR = 1.05 (95% CI: 0.96- 1.15), RR = 0.90 (95%CI: 0.81-1.01), RR = 0.96 (95% CI: 0.87-1.06), and RR = 0.99 (95%CI: 0.89-1.11). In other words, no relationship existed between dairy products and CHD. Conclusion: No relationship was found between consumption of various dairy products and CHD or stroke, except for cheese that decreased stroke risk by 7%. Considering the small number of studies, the result of the present study is not generalizable and more studies need to be conducted. PMID- 29445655 TI - A RCT comparing lumbosacral orthosis to routine physical therapy on postural stability in patients with chronic low back pain. AB - Background: Poor balance performance and impaired postural control have been frequently reported in patients with low back pain. However, postural control is rarely monitored during the course of treatment even though poor postural control may contribute to chronicity and recurrence of symptoms. Therefore, the present study aimed at investigating the effect of a nonextensible lumbosacral orthosis (LSO) versus routine physical therapy on postural stability of patients with nonspecific chronic low back pain. Methods: This was a randomized controlled trial conducted between November 2015 and May 2016 at the outpatient physical therapy clinic of the School of Rehabilitation Sciences. Patients with nonspecific chronic low back pain aged 20 to 55 years were randomly allocated to the intervention and control groups. Both groups received 8 sessions of physical therapy twice weekly for 4 weeks. The intervention group received nonextensible LSO in addition to routine physical therapy. Pain intensity, functional disability, fear of movement/ (re)injury, and postural stability in 3 levels of postural difficulty were measured before and after 4 weeks of intervention. A 2*2*3 mixed model of analysis of variance (ANOVA) was used to determine the main and interactive effects of the 3 factors including group, time, and postural difficulty conditions for each variable of postural stability. Results: The LSO and control groups displayed significant improvement in postural stability at the most difficult postural task conditions (P-value for 95% area ellipse was 0.003; and for phase plane, the mean total velocity and standard deviation of velocity was <0.001). Both groups exhibited a decrease in pain intensity, Oswestry Disability Index, and Tampa Scale of Kinesiophobia after 4 weeks of intervention. A significant difference between groups was found only for functional disability, with greater improvement in the orthosis group (t = 3.60, P<0.001). Conclusion: Both routine physical therapy and LSO significantly improved clinical and postural stability outcomes immediately after 4 weeks of intervention. The orthosis group did not display superior outcomes, except for functional disability. PMID- 29445656 TI - Epidemiological and clinical characteristics of scorpionism in Shiraz (2012 2016); development of a clinical severity grading for Iranian scorpion envenomation. AB - Background: Scorpionism is a public health problem in some provinces in Iran. The present study aimed to assess the clinical manifestations of scorpion envenomation in Shiraz and determine a clinical severity grading for Iranian scorpion envenomation in order to suggest a treatment guideline for emergency physicians. Methods: In this analytic retrospective study, all medical charts of patients with scorpion sting admitted in the adult medical toxicology center in Shiraz during July 2012 to July 2016 were assessed. Data regarding the patient's age, gender, sting site, month of envenomation, time of sting, clinical manifestations, vital signs, presence of blood or hemoglobin in urine analysis, duration of admission, color of scorpion, received treatments, and administration of scorpion antivenin were recorded. Results: The scorpions in Shiraz and its suburban area were classified into two groups: yellow scorpions ( Mesobuthus eupeus, Mesobuthus caucasicus , and Compsobuthus matthiesseni) and Hottentotta scorpions (Hottentotta jayakari and Hottentotta zagrosensis). A total of 126 cases of scorpion stings were assessed. About 59% (n=74) were males. The patients aged 8-63 years (mean age, 33.8+/-11.5 years). About 38.4% (n=48) of the stings occurred during summer. More than 40% of patients (n=51) referred to the emergency department (ED) at night. Localized pain was the most frequent presenting complaint (76.2%). The most frequent general symptom was nausea (6.3%). The most prevalent envenomation site was the lower extremities followed by upper extremities (43.5% and 41.9%, respectively). Based on the clinical severity grading for Iranian scorpion envenomation, 65, 43, and 18 patients (51.6%, 34.1%, and 14.3%) were classified in the grades I, II, and III, respectively. Eighty-one (73%) patients stayed in the ED from 1 to 6 hours, and 30 (27%) patients stayed for >6 hours for observation. Severe localized pain was more prevalent in stings with Hottentotta scorpions than yellow scorpions (P=0.01). The season of envenomation with Hottentotta scorpions was summer in all cases, but envenomation with yellow scorpions was seen throughout the year. All patients received symptomatic treatment, and five were given scorpion antivenin. No death was reported. Conclusion:Hottentotta jayakari is recommended to be listed among the medically important scorpions in Iran. Moreover, scorpion-stung patients in geographical regions where Hemiscorpius lepturus and Androctonus crassicauda are not prevalent may be treated in outpatient departments. The presented grading system can be used for treating patients with scorpion envenomation. PMID- 29445657 TI - Correlation of visfatin level with non-alcoholic fatty liver in metabolic syndrome. AB - Background: Metabolic syndrome (MS) and non-alcoholic fatty liver disease (NAFLD) is a common public health problem. Visfatin is secreted by visceral adipose tissue and is an adipocytokine. It could be a pro-inflammatory adipocytokine and is related to the metabolic syndrome and non-alcoholic fatty liver disease. This study evaluated the association between visfatin levels in patients with the metabolic syndrome with and without non-alcoholic fatty liver disease (NAFLD). Methods: In this cross-sectional study, 120 patients with metabolic syndrome were selected. They were categorized into two groups, patients with fatty liver (n=70) and without fatty liver disease (n=50). Laboratory and anthropometric options such as age, sex, systolic blood pressure, fasting blood sugar, lipid profile, liver enzymes, uric acid, visfatin, insulin, BMI, waist circumference, and TNF alpha were measured. The chi-square test, Mann-Whitney, t test, Spearman and Pearson correlations were used for the data analysis. Results: There was a significant difference between the fatty liver and non-fatty liver disease with visfatin, BMI, FBS and lipid profile (p<0.05). The mean+/-SD level of visfatin was 37.1+/-1.7 ng/dl in the non-fatty liver and was 44.4+/-1.5 ng/dl in fatty liver participants (p=0.02). 59% of patients with metabolic syndrome had fatty liver in ultrasonography. Conclusion: According to this study, there was a correlation between visfatin levels and fatty liver disease. PMID- 29445658 TI - Current status of health index in Tehran: A multidimensional approach. AB - Background: Health is an essential component of human rights and the rights are interdependent, indivisible, and correlated. The present study aimed at codifying a multidimensional health index according to multistage index development and describing the status of this index in 22 municipal districts of Tehran. Methods: This study was conducted using the data collected in the second round of Urban HEART Project of Tehran (2012-2013). The sample size was 34 700. To develop a multidimensional health index (MDHI), the nine steps of the Organization for Economic Cooperation and Development (OECD) were followed, from codifying theoretical framework to introducing the index. Results: According to the constructed MDHI, the districts no. 13, 10, 17, 1, 3, 4, and 22 had the best status and the district no. 8 the worst status. With respect to physical health, the districts no. 13, 17, 1, 3, 10, and 18 had the best status and the district no. 8 the worst. Concerning mental health, the districts no. 3, 6, 1, and 10 had the best status and the districts no. 8 and 12 the worst status. With respect to social health, the districts no. 10, 22, and 21 had the best status and the districts no. 6, 7, 12, and 14 the worst status. The analysis of sensitivity indicated that the MDHI was more sensitive towards physical health. Based on the mean, minimum, and maximum scores on each indicator of the questionnaires, the physical, mental, social, and MDHI status of Tehran residents (2012-2013) was high-medium, medium, low-medium, and high-medium, respectively. Conclusion: The right to health should be widely investigated, as it is a primary principle needed for sustainable development, which can be accomplished when the attitudes of different organizations towards the health construct are multidimensional rather than unidimensional. PMID- 29445659 TI - Clinical assessment of activities of daily living in acute stroke: Validation of the Persian version of Katz Index. AB - Background: Katz Index is a well-known index for assessing basic activities of daily living. The aim was to determine validity and reliability of the Katz Index in Iranian patients with acute stroke. Methods: Eighty-seven patients (56 male, 31 female) with acute stroke (1-30 days post-stroke) participated in this psychometric properties study. Interval time for retest was 14 days. All participants were Iranian with Persian as native language, had no other major diseases (e.g. cancer, Alzheimer) and no psychiatric disorder. Cognitive mental score of all participants was above 18 (according to Mini-Mental State Examination). If they had another stroke during the following-up period, they were excluded from the study. Intraclass Correlation Coefficient (ICC), Standard Error of Measurement (SEM) and Minimum Detectable Change (MDC) were calculated to investigate the reliability of the KI. Criterion validity of the KI was assessed by Spearman's Correlation Coefficient (rho). Moreover, Confirmatory Factor Analysis (CFA) and Exploratory Factor Analysis (EFA) were performed to investigate the construct validity of the KI. Results: Inter-rater and intra rater reliability of Persian Katz Index were reasonable (ICC2,1=0.93, ICC2,1=0.83; respectively). Internal consistency of this index was high (cronbach's alpha=0.79). The high to excellent correlation was found between Katz Index and the motion (rho=0.88), self-care (rho=0.98), and total scores (rho=0.92) of Barthel Index. Factor analysis of the Persian Katz Index indicated two factors including motion (bathing, toileting, and transferring) and self-care (dressing, bowel & bladder control, and feeding). Conclusion: The results of this study suggest that Persian version of Katz Index in patients with acute stroke can be considered as an acceptable clinical instrument in practice and research. PMID- 29445660 TI - Health technology assessment of magnet therapy for relieving pain. AB - Background: Magnet therapy has been used increasingly as a new method to alleviate pain. Magnetic products are marketed with claims of effectiveness for reducing pain of various origins. However, there are inconsistent results from a limited number of randomized controlled trials (RCTs) testing the analgesic efficacy of magnet therapy. This study aimed to evaluate the safety and effectiveness of magnet therapy on reliving various types of pain. Methods: A systematic search of two main medical databases (Cochrane Library and Ovid Medline) was conducted from 1946 to May 2014. Only English systematic reviews that compared magnet therapy with other conventional treatments in patients with local pain in terms of pain relieving measures were included. The results of the included studies were thematically synthesized. Results: Eight studies were included. Magnet therapy could be used to alleviate pain of various origins including pain in various organs, arthritis, myofascial muscle pain, lower limb muscle cramps, carpal tunnel syndrome and pelvic pain. Results showed that the effectiveness of magnetic therapy was only approved in muscle pains, but its effectiveness in other indications and its application as a complementary treatment have not been established. Conclusion: According to the results, it seems that magnet therapy could not be an effective treatment for relieving different types of pain. Our results highlighted the need for further investigations to be done in order to support any recommendations about this technology. PMID- 29445661 TI - Does the normal four steps weight-bearing rule predict the need for radiography in cases of blunt ankle trauma? AB - Background: Ankle injuries are one of the most common complaints of patients presenting to emergency departments (ED). The Ottawa ankle rules (OAR) was introduced to help physicians to decide who may require x-ray for blunt injuries. The present study aimed at validating the four steps weight-bearing rule of OAR as a sole criterion. Methods: This prospective observational study was conducted on 214 patients with acute ankle injury who referred to 3 emergency departments over a 7-months period in 2008. Main outcome measures of this survey included the sensitivity, specificity, positive and negative predictive values, and the likelihood ratios (positive and negative) of the four steps weight-bearing rule. Results: In this study, 34 fractures were found among the patients. The decision rule had a sensitivity of 0.88 and specificity of 0.61 in detecting all midfoot and ankle fractures. Application of this rule by emergency medicine residents resulted in a 47% reduction in the use of midfoot and ankle radiography. Conclusion: Applying a four steps weight-bearing rule as a sole criterion to detect ankle fractures is not as accurate and sensitive as OAR. Solitary application of this rule may lead to an increasing number of missed fractures compared with OAR. PMID- 29445662 TI - Footprint as an alternative to X-ray in hallux valgus angle measurement. AB - Background: X- ray images provide accurate and reliable data in different foot pathologies. However, the accompanied complications will limit its use for epidemiological studies and research purposes, especially in children. Therefore, simple, accessible, and cost- effective methods such as footprint, with a good correlation with x-ray images, are needed to help diagnose different foot pathologies. In the present study, the accuracy of footprint technique in assessing hallux valgus angle (HVA) was evaluated based on x-ray images through measuring the angle between the medial border protrusion of the foot and the hallux. Methods: In this cross-sectional study, 42 participants with symptomatic hallux valgus were recruited. HVA was measured by both x-ray imaging and footprint. The differences between the two approaches were identified by applying correlation-coefficient test and reliability, which was assessed using interclass correlation (ICC). Results: A significant correlation was found between the HVA measured by x-ray and HVA by footprints (p< 0.001), and the ICC was upper than 90%. Conclusion: Foot print is a reliable method for measuring HVA, as it was highly correlated with the HVAs obtained by x-ray imaging. PMID- 29445663 TI - Comparing minimally supervised home-based and closely supervised gym-based exercise programs in weight reduction and insulin resistance after bariatric surgery: A randomized clinical trial. AB - Background: Effectiveness of various exercise protocols in weight reduction after bariatric surgery has not been sufficiently explored in the literature. Thus, in the present study, we aimed at comparing the effect of minimally supervised home based and closely supervised gym-based exercise programs on weight reduction and insulin resistance after bariatric surgery. Methods: Females undergoing gastric bypass surgery were invited to participate in an exercise program and were randomly allocated into 2 groups using a random number generator in Excel. They were either offered a minimally supervised home-based (MSHB) or closely supervised gym-based (CSGB) exercise program. The CSGB protocol constitutes 2 weekly training sessions under ACSM guidelines. In the MSHB protocol, the participants received a notebook containing a list of recommended aerobic and resistance exercises, a log to record their activity, and a schedule of follow-up phone calls and clinic visits. Both groups received a pedometer. We measured their weight, BMI, lipid profile, FBS, and insulin level at baseline and at 20 weeks after the exercises, the results of which were compared using t test or Mann-Whitney U test at the end of the study. All the processes were observed by 1 senior resident in sport medicine. Results: A total of 80 patients were recruited who were all able to complete our study (MSHB= 38 and CSGB= 42). The baseline comparison revealed that the 2 groups were similar. The mean change (reduction) in BMI was slightly better in CSGB (8.61 95% CI 7.76-9.45) compared with the MSHB (5.18 95% CI 3.91-6.46); p< 0.01. However, the 2 groups did not have a statistically significant difference in the amount of change in the other factors including FBS and Homa.ir. Conclusion: As we expected a non-inferiority result, our results showed that both MSHB and CSGB exercise methods are somewhat equally effective in improving lipid profile and insulin resistance in the 2 groups, but a slightly better effect on BMI was observed in CSGB group. With considerably lower costs of minimally supervised home- based exercise programs, both methods should be considered when there is lack of adequate funding. PMID- 29445664 TI - Unmet needs in Iranian cancer patients. AB - Background: The identification and management of unmet needs is an essential component of health care for the growing cancer patient population. Information about the prevalence of unmet need can help medical service planning/redesigning. Therefore, this study aimed to identify unmet needs in Iranian patients suffering from cancer. Methods: This cross-sectional correlational study was conducted on 650 cancer patients admitted to the major medical centers in Mashhad and Neyshabur by census sampling. The data was gathered by the Survivor Unmet Needs Survey (SUNS). Data were analyzed using ANOVA, t-test and Pearson correlation. Results: Most of participants were female (56%, n=263) and Mashhad resident (67.1%, n=436). The most common cancers were colorectal (17.8 %, n=116), stomach (13.6%, n=88) and lung (9.4%, n=62), respectively. The highest unmet needs score belonged to work and financial needs (2.46 +/- 0.91), and the least was the emotional domain (1.92+/-0.90). Among demographic factors, a significant relationship was found between resident places (p<0.001), and cancer type (p<0.0001). Conclusion: This is the first study addressing the unmet needs of cancer patients in Iran. It reveals that cancer patients had a relative high number of unmet needs; this shows the necessity of including these factors in the routine assessment of all cancer patients and planning treatment interventions based on their individual's need. PMID- 29445665 TI - Envelope-based inter-aural time difference localization training to improve speech-in-noise perception in the elderly. AB - Background: Many elderly individuals complain of difficulty in understanding speech in noise despite having normal hearing thresholds. According to previous studies, auditory training leads to improvement in speech-in-noise perception, but these studies did not consider the etiology, so their results cannot be generalized. The present study aimed at investigating the effectiveness of envelopebased interaural time difference (ITD ENV) localization training on improving ITD threshold and speech-in-noise perception. Methods: Thirty-two elderly males aged 55 to 65 years with clinically diagnosed normal hearing at 250 2000 Hertz, who suffered from speech-in-noise perception difficulty participated in this study. These individuals were randomly divided into training and control groups: 16 elderlies in the experimental group received envelope-based interaural time difference localization training in 9 sessions, but 16 matched elderlies in the control group did not receive any training. The ITD ENV threshold and spatial word recognition score (WRS) in noise were analyzed before and after the localization training. Results: Findings demonstrated that following the training program, the interaural time difference envelope threshold and spatial word recognition score (WRS) in noise were improved significantly in the experimental group (p<= 0.001). Moreover, a significant difference was detected in interaural time difference envelope threshold and spatial word recognition score (WRS) in noise (p<= 0.001) before and after the training in the experimental group. Conclusion: The results of the present study revealed the effectiveness of envelope- based interaural time difference localization training in localization ability and speech in noise perception in the elderlies with normal hearing up to 2000 Hz who suffered from speech-in-noise perception difficulty. PMID- 29445666 TI - Perioperative changes in platelet count and function in patients undergoing cardiac surgery. AB - Background: Patients undergoing cardiac surgery are at increased risk of bleeding due to multifactorial coagulopathies. In the present study, we aimed at investigating the changes in platelet count and function during and after surgery as well as determining the association of the platelet dysfunction with bleeding and transfusion requirements in these patients. Methods: A total of 40 adult patients scheduled for elective valve coronary cardiac surgery were included in this prospective observational study. Changes in platelet count and function with ADP, acid arachidonic, and collagen (light transmission aggregometry) were analyzed at three time points: before CPB, after CPB, and 24 hours after end of surgery. Postoperative bleeding and intraoperative transfusion requirements were recorded. Results: There were a significant reverse correlation between CPB time and ADP-induced aggregation, particularly after CPB and postoperative AA-induced aggregation. There was not any significant correlation between platelet count and function at all-time points. Both platelet count and platelet aggregation significantly reduced during CPB. While platelet aggregation increased on postoperative Day 1, platelet count reduced by about 40% after CPB, and remained at this level postoperatively. Patients with abnormal ADP-induced aggregation had significant increased postoperative bleeding and transfusion requirements. Conclusion: The results of this study demonstrate that platelet count and platelet aggregation are reduced during CPB. Our results emphasized the effect of platelet dysfunction on increased postoperative bleeding and transfusion requirements. Perioperative monitoring of platelet function can be considered as a bleeding management strategy for implantation of PBM programs. PMID- 29445667 TI - Determination of lymphocytes surface markers in patients with thermal burns and the influence of burn size on mononuclear cell subsets. AB - Background: Thermal burn injuries impair the host defence system. Hence, in the present study, we aimed at investigating the changes in the number and phenotype of peripheral blood lymphocyte populations (T, B, and natural killer cells) and their subpopulations in patients with thermal burns and determining the relationships with different sizes of total body surface area (TBSA). Methods: Blood samples from 67 patients, admitted to Motahary Burn Center in Tehran, with burns from 30% to more than 70% TBSA were collected on Days 3 and 7 postburn. Lymphocytes and their subpopulations were identified by monoclonal antibodies. The cells were analyzed using flow cytometry. The results were compared with healthy controls. Results: In this study, 3 and 7 days after burn injury, the percentages of CD3+, CD4+ and CD8+ lymphocyte significantly decreased, CD4+/CD8+ ratios were below the normal range, and CD19+ (B cells) significantly increased. No significant difference was obtained in the mean percentage of CD16+ (NK cells) between Days 3 and 7 postburn. Patients with burns of 30% TBSA or greater (>70%) had a significant reduction in CD3+, CD4+ and CD8+ ( T cells) numbers up to 7 days compared with 3 days after burn injury. Patients with 30% to >70 % TBSA burn failed to show any significant changes in CD4+/CD8+ ratio as well as CD16+ (NK cells) 3 to 7 days after burn. In patients with burns more than 30% to>70% TBSA, CD19+ (B cells) number changes were found to be complicated after 3 and 7 days. Conclusion: The results of this study suggest that alterations of immune cell surface markers and TBSA% can reflect postburn lymphocyte activation. PMID- 29445668 TI - Cost-effectiveness of teriparatide compared with alendronate and risedronate for the treatment of postmenopausal osteoporosis patients in Iran. AB - Background: Hip, vertebral and wrist fractures are the most common consequences of osteoporosis. This study aimed at analyzing the cost-effectiveness of teriparatide (CinnoPar(r)), compared with alendronate and risedronate, in the treatment of women aged 60 and over with postmenopausal osteoporosis in Iran. Methods: A decision tree model with a 2-year time horizon was used to compare treatment with teriparatide (CinnoPar(r)) with the following treatment strategies: two years of treatment with alendronate and two years of treatment with risedronate in women aged 60 years and over or those at risk of osteoporosis. Cost per QALY was calculated for 3 treatment strategies from the model. After base case analysis, one-way sensitivity analysis was performed on key parameters of the model to assess their impact on the study results and the cost-effectiveness of different treatment strategies and the model robustness. TreeAge Pro 2006 software was used for modeling and data analysis. Results: Incremental cost-effectiveness ratio (ICER) of alendronate and teriparatide than risedronate (base treatment) were US$- 2178.03 and US$483,783.67 per QALY, respectively. Therefore, the dominant and cost-effective treatment option was alendronate. In the one-way sensitivity analysis, the impact of annual 25% increase or decrease in the teriparatide cost on its ICER was remarkable. Also, reducing the discount rate from 0.03 to 0.0 had the greatest impact on the ICER of the teriparatide. Conclusion: The treatment strategy of teriparatide is more expensive than risedronate and alendronate and is associated with very little increase in QALYs. A significant reduction in teriparatide price and a limit in its use only for high-risk women and for acute and short-term treatment courses can contribute to its cost-effectiveness. PMID- 29445669 TI - Males' perspectives on health in Iran: A grounded theory study. AB - Background: Males' health plays a basic role in the community's health, especially in family's health. Health is a multifaceted issue that affects people in all aspects. Health is also one of the 4 metaparadigm concepts in nursing. This study was conducted to explore males' perspectives on health. Methods: In this qualitative study conducted based on a grounded theory approach, 22 males were selected through a purposive sampling. Data were collected through semi structured interviews and continued until data saturation. Data analysis was done using Strauss and Corbin's three-stage coding process. Results: Based on the perspectives of the participants, 8 categories emerged, which are as follow: psychological health; physical health; family health; spiritual health; welfare and social health; health and relationships; sexual health; and occupational economic health. Psychological health was emerged as the core variable. Conclusion: As a multifaceted phenomenon, health is an individual's general condition in all these aspects, particularly psychological aspect. Males' health should be taken into account for the role they play in managing the family. Males as the family heads require evidence-based decision making and planning. PMID- 29445670 TI - General practitioners' views on key factors affecting their desired income: A principal component analysis approach. AB - Background: Based on the target income hypothesis, the economic behavior of physicians is mainly affected by their target income. This study aimed at designing an instrument to explain how general practitioners (GPs) set their desired income. Methods: A self-administered questionnaire of affecting factors on GPs' target income was extracted from literature reviews and a small qualitative study. Respondents were 666 GPs who completed the questionnaire (response rate= 52%) during 2 seasonal congresses of Iranian GPs. The principal component analysis (PCA) with varimax rotation was used to classify the variables and data reduction. Sample adequacy test, sphericity test, eigenvalues of components, and scree plot were evaluated for PCA. Cronbach's alpha was also checked to assess the internal consistency of the principal components. Results: The results of the KMO measure of sampling adequacy (0.657) and Bartlett's test of sphericity (809.05, p<0.001) revealed that the collected data were suitable for PCA. Based on the scree plot pattern and eigenvalues greater than 1, 6 components including perceived comparative income, importance of responsiveness to patients, perceived socioeconomic status, economic expectations, socioeconomic status of paternal family, and provision of luxury services were selected, which explained 65.19% of the total variance. Finally, only those with a Cronbach's alpha value higher than 0.6 were considered reliable (the first 4 components). Conclusion: Based on the target income hypothesis, a physician's desired level of income affects their behavior. Our developed instrument and its mentioned components can be used in future studies related to GPs' behavior, especially those studies related to the economic aspects of GPs' behavior. It also helps formulate a better payment mechanism for primary care providers. PMID- 29445671 TI - A seroprevalence and relationship survey of brucellosis between pregnant women and women with spontaneous abortion in Iran. AB - Background: Brucellosis is one of the most prevalent diseases common between humans and animals. It is also called Malta fever, Undulant fever and Mediterranean fever. This disease is spread by consuming milk and its unpasteurized derivatives. Clinical symptoms of brucellosis in humans are fever, chills, headache, muscular pain, tiredness, loss of appetite, joint pain, weight loss, constipation, sore throat, and dry cough. The present study aimed at surveying the seroprevalence of brucellosis in pregnant women and those women who suffered from spontaneous abortion. Methods: This case- control study was conducted in Sanandaj (Iran) in 2016 and included 2 groups of pregnant women: one group included 160 pregnant women and the other included 160 women who suffered from spontaneous abortion. Then, the participants were asked to fill out the questionnaire. After receiving permission from an obstetrician, a 10-cc blood sample was taken from each person to be used in the Rose Bengal, Wright, 2ME, and Coombs tests. Independent samples t test and Chi-square test were used to analyze the data and compare the groups. Results: Mean+/-SD age of women in the case group was 30.9+/-7.3 years, while it was 27.74+/-5.41 years in control women. The Rose Bengal, Wright, and 2ME prevalence for both groups was negative, but the Coombs and Wright tests score was 33 (20.6%) in pregnant women and it was 27 (16.9%) in women who experienced spontaneous abortion. No meaningful relationship was observed between spontaneous abortion and brucellosis (p= 0.39). Conclusion: Even though the present study did not find a meaningful relationship between spontaneous abortion and brucellosis (p=0.39), high brucella seroprevalence rates between both groups of women indicated that screening tests should be considered before gestation as an appropriate therapeutic strategy. PMID- 29445672 TI - Catastrophic health expenditure among households with members with special diseases: A case study in Kurdistan. AB - Background: One of the main goals of health systems is to protect people against financial risks associated with diseases that can be catastrophic for patients. In 2014, Health Sector Evolution Plan (HSEP) was implemented in Iran; one of the objectives of HSEP was to reduce out-of-pocket payments and provide more financial protection for people. Therefore, the present study aimed at exploring the likelihood of facing catastrophic health expenditures (CHE) among households with members suffering from dialysis, kidney transplant, or multiple sclerosis (MS) after the implementation of HSEP. Methods: A total number of 385 households were selected using stratified random sampling and were asked to complete the World Health Survey questionnaire through telephone conversations. As outlined by the World Health Organization (WHO), when household out-of-pocket expense for health services is >=40% of its capacity to pay, then that household is considered to be facing CHE. Furthermore, determinants of CHE were identified using logistic regression. Results: The percentage of facing catastrophic health care expenditures for households with a MS, dialysis, and kidney transplant patient was 20.6%, 18.7%, and 13.8%, respectively. Results of logistic regression analysis revealed that patient's economic status, level of education, supplementary insurance status, type of disease, multiple members with special diseases in the household, rural residence, use of inpatient, dental, and rehabilitation services were effective factors for determining the likelihood of facing CHE. Conclusion: Despite the implementation of HSEP, the percentage of CHE is still high for households that have members who suffer from special diseases. However, basic health insurance packages should be amended and more cost-sharing exemptions should be granted to provide more financial protection for the vulnerable households. PMID- 29445673 TI - Periodontitis in rheumatoid arthritis patients, abundance and association with disease activity. AB - Background: There are some discrepancy in association between activity of rheumatoid arthritis (RA) and periodontitis. The aim of this study was to evaluate the periodontal status of outpatients with RA. Methods: The study was conducted in 2013-14 in a rheumatology clinic in Sari, north of Iran on 74 patients with RA. Evaluation of RA disease activity was according to disease activity score 28 (DAS28). Periodontitis was evaluated by probing depth (PD), gingival index (GI), clinical attachment level (CAL index), plaque index (PI), and panoramic X-ray. Statistical analysis included independent ttest and Mann Whitney U test for quantitative, and chi square and OR for qualitative variables and evaluation of RA activity and periodontitis severity. Results: The mean+/-SD of age and disease duration were 47.01+/-8.1 and 8.93+/-8.6 years, respectively and the mean+/-SD number of teeth was 20.70+/-6.8. Twenty-seven (36.5%) patients had moderate to severe disease. Forty-seven cases (63.5%) were found with periodontitis and 14 (12.2%) were identified to have moderate to severe periodontitis, unrelated to disease activity (p=0.22). For active/inactive periodontitis OR =1.33 (95% CI: 0.46 - 3.87) was computed. There was no association between RA disease activity and number of teeth, CAL, PI, PD, and GI, (p>0.05). Conclusion: About 60% of RA patients suffered from periodontitis, but there was not any significant relation between RA disease activity and severity of periodontitis. Periodontitis may interfere with management and follow up of RA, so periodic periodontal examination is suggested in these patients. PMID- 29445674 TI - Experiences of substance abusers from methadone maintenance therapy. AB - Background: Substance abusers are not able to withdraw drugs eternally despite the abundance of different treatments; therefore, withdrawal programs are not quite successful and notwithstanding all the successes of methadone maintenance therapy, there are some defects found in the manner this treatment is applied. Thus, this study was conducted to explore the experience of drug abusers regarding methadone maintenance therapy. Methods: This is a qualitative study using content analysis methodology. The research community includes drug abusers admitted to the treatment centers of the western cities of Mazandaran Province, Iran in 2016. The sampling was purposive and the data were collected by face-to face single interviews with 20 patients. The interviews were continued up to data saturation. Finally, the Lundman and Grenheim method was used to analyze the interviews and the four criteria of Guba and Lincoln were applied to check data integrity. Results: "Buying time," "methadone dependence," and "looking from a narrow view to the patient" were the main three categories that fit the results. Conclusion: Governmental free services for drug abusers; paying attention to different aspects of treatment such as mental, emotional, and social recovery; lifelong support of the family and society members; and balance in prescribing and following the treatment process prescribed by health care providers can enhance both the quality and safety of the treatment process. Psychological consultation alongside social services can facilitate the recovery process in methadone maintenance therapy. PMID- 29445675 TI - Psychosocial experiences of the internet in a group of adolescents: A qualitative content analysis. AB - Background: Social networking has a dramatically increasing trend among adolescents. By creating novel models of content production, distribution, and reception, this space has introduced opportunities and threats for adolescents, which must be understood in relation with their health status. This study was conducted with the aim of describing the psychosocial experiences of Iranian adolescents in the Internet's virtual space. Methods: The present qualitative formal content analysis was conducted in Mashhad a city Iran. The participants included 32 adolescents of 13-18 years of age. Data were collected through 32 semi-structured individual and group interviews with maximum variation. The data were recorded, transcribed, and then analyzed via MAXQ 10 software. Results: In this study, 2 main themes of "moving towards constructiveness" and "perceiving social and psychological tensions" were formed. Accordingly, 9 subcategories were formulated including: increasing the social capital, a good feeling in life, escaping loneliness, being seen in the social network, intelligent selection of content, perceived threats, temptation, decline of behavioral values and principles, and emotional and social helplessness. Conclusion: Adolescents' positive and negative experiences in the Internet form based on personal and environmental factors. These experiences affect the mental and social dimensions of their health. These factors call for the attention of scholars and policymakers for developing enabling strategies for adolescents, and their families and for experts for promoting adolescents' health. PMID- 29445676 TI - Rationing in health systems: A critical review. AB - Background: It is difficult to provide health care services to all those in need of such services due to limited resources and unlimited demands. Thus, priority setting and rationing have to be applied. This study aimed at critically examining the concept of rationing in health sector and identifying its purposes, influencing factors, mechanisms, and outcomes. Methods: The critical interpretive synthesis methodology was used in this study. PubMed, Cochrane, and Proquest databases were searched using the related key words to find related documents published between 1970 and 2015. In total, 161 published reports were reviewed and included in the study. Thematic content analysis was applied for data analysis. Results: Health services rationing means restricting the access of some people to useful or potentially useful health services due to budgetary limitation. The inherent features of the health market and health services, limited resources, and unlimited needs necessitate health services rationing. Rationing can be applied in 4 levels: health care policy- makers, health care managers, health care providers, and patients. Health care rationing can be accomplished through fixed budget, benefit package, payment mechanisms, queuing, copayments, and deductibles. Conclusion: This paper enriched our understanding of health services rationing and its mechanisms at various levels and contributed to the literature by broadly conceptualizing health services rationing. PMID- 29445677 TI - Accuracy of ultrasonography in diagnosing acute appendicitis during pregnancy based on surgical findings. AB - Background: Acute appendicitis is the most common nonobstetric surgical problem in pregnancy. Common signs and symptoms of appendicitis are less reliable during pregnancy due to physiological changes; thus, the role of imaging becomes prominent. Thus, in the present study, we aimed at assessing the accuracy of sonography in diagnosing acute appendicitis during pregnancy. Methods: In this prospective analytic study, among 1000 patients diagnosed and treated as acute appendicitis, clinical and sonographic findings of 58 consecutive pregnant patients, who underwent appendectomy, were recorded and analyzed. All surgically resected samples were evaluated and confirmed through histological evaluation. Sonographic criteria were utilized to judge the results for appendicitis. Diagnostic test performance characteristics (sensitivity, specificity, predictive values, and likelihood ratios) were calculated. Results: The mean age of the patients was 27.1+/-4.9 years, and the most common clinical symptom was right lower quadrant pain. There was no significant difference in the mean leukocyte count between the appendicitis group and normal appendix group (p=0.768). Left shift was also unrelated with the appendix pathology (p= 0.549). The sensitivity, specificity, predictive values (positive and negative), and likelihood ratios (positive and negative) were 80%, 75%, 91.4%, 52.9%, 3.2, and 0.26, respectively during all trimesters of pregnancy. Conclusion: Ultrasonography is the initially preferred imaging modality in pregnant women suspected of having acute appendicitis with an acceptable sensitivity; however, application of other imaging modalities such as CT scan or MRI is recommended after inconclusive ultrasonography results. PMID- 29445678 TI - Effectiveness of psychosocial interventions in abused children and their families. AB - Background: Child abuse is a significant public health and social problem worldwide. It can be described as a failure to provide care and protection for children by the parents or other caregivers. This study aimed at evaluating the effectiveness of psychosocial interventions in abused children and their families. Methods: This quasi-experimental study was conducted in the psychosocial support unit of a pediatric hospital in Bandar Abbas, Iran, from 2012 to 2013. The participants consisted of child abuse cases and their parents who referred to the psychosocial support unit to receive services. Services delivered in this unit included parenting skills training, psychiatric treatments, and supportive services. The effectiveness of the interventions was assessed with Child Abuse Questionnaire, General Health Questionnaire (GHQ), and Strengths and Difficulties Questionnaires (SDQ). Participants were assessed at baseline, at 3, and 6 months follow-ups. ANOVA with repeated measures and Friedman test were used to evaluate the effect of the interventions. Results: A total of 68 children and their parents enrolled in this study, of whom 53% were males. Post-intervention follow-ups revealed significant changes in mothers' general health questionnaire (p<0.001), and children's conduct problem (p<0.05), hyperactivity (p<0.001), and peer problems (p<0.05). Physical and emotional abuses significantly decreased (p<0.001). Conclusion: Our findings revealed that psychosocial interventions effectively improved child-parents interaction and mental health of parents. The effectiveness of interventions based on subgroup analysis and implications of the results have been discussed for further development of psychosocial interventions in the health system. PMID- 29445679 TI - Sentinel lymph node in cervical cancer. AB - Background: Cervical cancer is the second most common type of cancer among women. Effective screening programs can help cancer detection in early phases and reduce death. Metastasis to lymph nodes is one of the most prognostic factors in patients who underwent surgery. Also, a positive result from pathology report alert oncologist as a cause of death. Sentinel lymph node biopsy has been widely studied and clinically used for many types of cancer. Methods: Two techniques exist for detecting sentinel node in cervical cancer, which are Blue dye and gamma probe with radioactive isotope (99mTc). Moreover, lymphoscintigraphy has many advantages over the stain method. Detecting the sentinel node is performed via laparoscopy or laparotomy; former method is better and more accurate. Results: Various researchers have focused on this method and its positive results; its superiority against full lymphadenectomy has been declared in previous studies. Moreover, the role of sentinel lymph nodes biopsy in cervical cancer is still being extensively studied. Sentinel lymph nodes (SLN) method has a higher accuracy level to detect metastasis. Conclusion: Hence, it can be considered as a more appropriate alternative for pelvic lymph node dissection (PLND), which is a standard technique. Altering the method to a standard clinical method needs in-depth researches and studies. PMID- 29445680 TI - Cultural barriers in access to healthcare services for people with disability in Iran: A qualitative study. AB - Background: People with disability experience various problems to access to healthcare services. This study aimed to identify cultural barriers in access to healthcare services for people with disability in Iran. Methods: We conducted a qualitative study using content analysis to identify the cultural barriers. We used semi-structured interviews to collect data. Participants were selected through purposeful sampling with maximum variation. 50 individual interviews were conducted with three groups of people with disability, healthcare services providers and policy makers, September to May 2015, at different locations in Tehran, Iran. Results: We identified a number of different cultural barriers in access to health services for people with disability in Iran. These related to health service providers, namely reluctance to provide health services and disrespect; related to People with disability, namely denial of disability, disproportionate expectation, shame and insufficient sociocultural supports; and related to policy makers, namely lack of concern, little attention to the culture of disability and discrimination. We categorized misconception as a barrier that was observed at all levels of the society. Conclusion: Disability is a reality that some human being may experience and live with it. The negative attitude towards people with disability has a close relationship with the cultural norms of a society. The culture of disability in different dimensions should be a priority for all policy makers. Removing cultural barriers in access to healthcare for people with a disability needs collective efforts and collaborations among all stakeholders. PMID- 29445681 TI - Digital games in medical education: Key terms, concepts, and definitions. AB - Introduction: Game-based education is fast becoming a key instrument in medical education. Method: In this study, papers related to games were filtered and limited to full-text peer-reviewed published in English. Results: To the best of researchers' knowledge, the concepts used in the literature are varied and distinct, and the literature is not conclusive on the definition of educational games for medical education. Conclusion: This paper attempts to classify terms, concepts and definitions common to gamification in medical education. PMID- 29445682 TI - Changes of the brain's bioelectrical activity in cognition, consciousness, and some mental disorders. AB - Background: An electroencephalogram (EEG) is an accepted method in neurophysiology with a wide application. Different types of brain rhythms indicate that simultaneous activity of the brain cortex neurons depend on the person's mental state. Method: we have focus on reviewing the existing literature pertaining to changes of the brain's bioelectrical activity that recorded from the scalp in different conditions such as cognition and some mental disorders. Result: The frequency of brain waves may indicate sleep, consciousness, cognition, and some mental disorders. Slow brain waves are seen in some conditions such as sleep, coma, brain death, depression, autism, brain tumors, obsessive-compulsive disorder (OCD), attention deficit hyperactivity disorder (ADHD), and encephalitis, while rapid waves are generally reported in conditions such as epilepsy, anxiety, posttraumatic stress disorder (PTSD), and drug abuse. Conclusion: Increase in the EEG rhythm is a marker of high brain activity that leads to high degrees of consciousness, while slow waves are suggestive of less brain activity. The pattern of EEG rhythm can be an indicator of some mental disorders, too. PMID- 29445683 TI - Comparison of the Joel-Cohen-based technique and the transverse Pfannenstiel for caesarean section for safety and effectiveness: A systematic review and meta analysis. AB - Background: Caesarean section (C-section) is the most common surgery among women worldwide, and the global rate of this surgical procedure has been continuously rising. Hence, it is significantly crucial to develop and apply highly effective and safe caesarean section techniques. In this review study, we aimed at assessing the safety and effectiveness of the Joel-Cohen-based technique and comparing the results with the transverse Pfannenstiel incision for C-section. Methods: In this study, various reliable databases such as the PubMed Central, COCHRANE, DARE, and Ovid MEDLINE were targeted. Reviews, systematic reviews, and randomized clinical trial studies comparing the Joel-Cohen-based technique and the transverse Pfannenstiel incision were selected based on the inclusion criteria. Selected studies were checked by 2 independent reviewers based on the inclusion criteria, and the quality of these studies was assessed. Then, their data were extracted and analyzed. Results: Five randomized clinical trial studies met the inclusion criteria. According to the exiting evidence, statistical results of the Joel-Cohen-based technique showed that this technique is more effective compared to the transverse Pfannenstiel incision. Metaanalysis results of the 3 outcomes were as follow: operation time (5 trials, 764 women; WMD -9.78; 95% CI:-14.49-5.07 minutes, p<0.001), blood loss (3 trials, 309 women; WMD 53.23ml; 95% -CI: 90.20-16.26 ml, p= 0.004), and post-operative hospital stay (3 trials, 453 women; WMD -.69 day; 95% CI: 1.4-0.03 day, p<0.001). Statistical results revealed a significant difference between the 2 techniques. Conclusion: According to the literature, despite having a number of side effects, the Joel Cohen-based technique is generally more effective than the Pfannenstiel incision technique. In addition, it was recommended that the Joel-Cohen-based technique be used as a replacement for the Pfannenstiel incision technique according to the surgeons' preferences and the patients' conditions. PMID- 29445684 TI - Efficacy of commercial formulas in comparison with home-made formulas for enteral feeding: A critical review. AB - Background: In several disease conditions, patients must inevitably be nourished by enteral feeding (EF). Though in many countries, commercial formulas are routinely used for EF, in Iran still home-made formulas are commonly employed as commercial formulas are not covered by insurance. This may pose patients to malnutrition and bring about further costs. The aim of this study was to evaluate the efficacy of EF commercial formulas in comparison with home-made formulas and thus to make further evidence for insurance policy-making Methods: Medline, Cochrane, Embass and Center for Review & Dissemination (CRD) as well as IranDoc and SID databases were searched. Keywords included formula, ICU, and enteral nutrition or tube feeding. No clinical trial study on the efficacy of EF formulas was found. Therefore, the compositions of available formulas and their cost effectiveness were evaluated based on the clinical guidelines of scientific bodies such as American Society for Parenteral and Enteral Nutrition (ASPEN), European Society for Parenteral and Enteral Nutrition (ESPEN) and relative articles available in PubMed. In addition, the expert opinions were also taken into consideration. Results: Domestic commercial formulas seemed to less merit dietary recommended intakes, i.e. the amount of some nutrients were much higher, and some others were much lower than the recommended values. The amount of several micronutrients including vitamins B1, B6, C, D and K, as well as iron, calcium and magnesium were not sufficient to meet the body needs in most commercial formulas upon receiving 2000 kilocalories and less. Conclusion: Clinical studies on the efficacy of commercial formulas in comparison with home made formulas are needed. Meanwhile, making suitable conditions for increasing the diversity of artificial nutrition products in the market would help clinical nutritionists to make better choices according to their patients conditions and to reduce the costs, as well. PMID- 29445685 TI - Comparison of intramuscular progesterone with oral nifedipine for treating threatened preterm labor: A randomized controlled trial. AB - Background: Threatened preterm labor (TPL) is the leading cause of hospitalization during pregnancy. Tocolytic agents are the primary therapeutic options for TPL. The aim of this study is to compare intramuscular progesterone with oral nifedipine as a tocolytic agent. Methods: This randomized controlled trial was carried out in a teaching hospital (Shahid Akbarabadi) in Tehran, Iran, from December 2011 to November 2012. Three hundred and fifteen singleton pregnant women aged >18 yrs at 26-34 weeks' gestation with the diagnosis of threatened preterm labor (TPL) were randomly received either intramuscular progesterone or oral nifedipine for tocolysis. Maternal and neonatal outcomes were then compared between the two interventions. P value less than 0.05 was considered statistically significant. IRCT registration number of this study is IRCT201112198469N1 Results: The success rate of progesterone and nifedipine in treating TPL were 83% and 82.7%, respectively. There was no significant difference between the two interventions with regard to gestational age at delivery, type of delivery, the time interval until the delivery, birth weight, NICU admission rate and hospital stays. Progesterone administration was associated with lower duration of NICU stay as compared with nifedipine (0.33+/ 0.77 days vs.1.5+/-3.2 days, p<0.05). None of the two drugs caused any major side effects. Conclusion: Single dose intramuscular progesterone is as effective as oral nifedipine in treating TPL. It also significantly reduces the NICU stay. PMID- 29445686 TI - Prevalence of proline racemase/ hydroxyproline epimerase gene in human brucella isolates in Iran. AB - Background: Human brucellosis is a zoonotic disease caused by Brucella melitensis, Brucella abortus, and Brucella suis. Brucella causes a chronic disease, which subverts the immune defense system of their hosts. In this study, the prevalence of an important Brucella virulence determinant, prpA, which can modulate immune response, was determined in human isolates. Methods: Polymerase chain reaction (PCR) assay was standardized and applied to 37 isolates obtained from patient's specimens. Primers for prpA gene were designed and evaluated using bioinformatic tools. DNA sequencing was performed for further verification. Results: In the 37 Brucella isolates (31 Brucella melitensis and 6 Brucella abortus), 32 (86.4%) carried prpA gene. Conclusion: Presence of prpA gene in most isolates indicates the high prevalence of this gene among Iranian isolates and emphasizes its role in pathogenicity of this organism. PMID- 29445687 TI - Gender is a risk factor in patients with gastroesophageal reflux disease. AB - Background: Prevalence of gastroesophageal reflux disease (GERD) has increased in the last decades, and it is now one of the most common chronic and recurrent diseases. The present study aimed at determining the frequency of gender (sex) and age in Iranian patients with GERD symptoms. Methods: In this study, 803 patients aged 11 to 84 years, with erosive and nonerosive gastroesophageal reflux diseases, based on the questionnaire and esophagogastroduodenoscopy findings, participated. The female group was compared with the male group with respect to age, symptoms, esophageal injury, and hiatus hernia. Results: Of the 803 participants, 60.5% (n= 486) were female, and 69.2% (n= 555) were younger than 50 years. Of those patients older than 50 years, 32.8% (n= 81) were female. Moreover, 31.0% (n= 249) of the patients had erosive esophagitis (ERD), and 69.0% (n= 254) had normal esophageal mucosa (NERD).The female to male ratio was 1/1.06 and 1.94/1 in ERD and NERD patients, respectively. Hiatal hernia was more prevalent in females than in males. Conclusion: Nonerosive reflux disease, as a gastroesophageal reflux disease (GERD), was more common in females than in males. GERD became more prevalent with increase in age. Gender and hiatal hernias were 2 potential risk factors of GERD. PMID- 29445688 TI - Complementary health insurance, out- of- pocket expenditures, and health services utilization: A population- based survey. AB - Background: Studies have shown that people using complementary health insurances have more access to health services than others. In the present study, we aimed at finding the differences between out- of- pocket payments and health service utilizations in complementary health insurances (CHIs) users and nonusers. Methods: Propensity score matching was used to compare the 2 groups. First, confounder variables were identified, and then propensity score matching was used to compare out- of- pocket expenditures with dental, general physician, hospital inpatient, emergency services, nursing, midwifery, laboratory services, specialists and rehabilitation services utilization. Results: Our results revealed no significant differences between the 2 groups in out- of- pocket health expenditures. Also, the specialist visits, inpatient services at the hospital, and dental services were higher in people who used CHIs compared to nonusers. Conclusion: People did not change their budget share for health care services after using CHIs. The payments were equal for people who were not CHIs users due to the increase in the quantity of the services. PMID- 29445689 TI - The effect of 3,4- methylenedioxymethamphetamine on expression of neurotrophic factors in hippocampus of male rats. AB - Background: 3,4- methylenedioxymethamphetamine (MDMA) is a chemical derivative of amphetamine that can induce learning and memory impairment. Due to the effect of neurotrophins on memory and learning, the impact of MDMA was evaluated on the brain - derived neurotrophic factor (BDNF), neurotrophin- 4 (NT-4), and tropomyosin- related kinase B (Trk- beta) expression in the hippocampus. Methods: In this study, 20 adult male Wistar rats (200-250 g) received saline (1 mL) or 10 mg/kg of MDMA intraperitoneally as single or multiple injection for 2 consecutive days per week for 2 months. Expression of BDNF, Trk-beta, and NT4 were assessed using Western blotting and RT PCR methods. Results: Our results revealed that the expression of BDNF, Trk- beta, and NT4 proteins and genes significantly decreased in MDMA groups compared to the sham group (p<0.05). Furthermore, the acute group showed the lowest expression of these proteins. Conclusion: The results of the present study suggest that ecstasy administration may downregulate the expression of BDNF, Trk- beta, and NT-4 in hippocampus, which is more extensive in case of acute treatment. It seems that in the chronic group, hippocampus was able to compensate the ecstasy- induced neurotoxicity. PMID- 29445690 TI - The paced auditory serial addition test for working memory assessment: Psychometric properties. AB - Background: The paced auditory serial addition test (PASAT) was primarily developed to assess the effects of traumatic brain injury on cognitive functioning. Working memory (WM) is one of the most important aspects of cognitive function, and WM impairment is one of the clinically remarkable signs of aphasia. To develop the Persian version of PASAT, an initial version was used in individuals with aphasia (IWA). Methods: In this study, 25 individuals with aphasia (29-60 years) and 85 controls (18-60 years) were included. PASAT was presented in the form of recorded 61 single-digit numbers (1 to 9). The participants repeatedly added the 2 recent digits. The psychometric properties of PASAT including convergent validity (using the digit memory span tasks), divergent validity (using results in the control group and IWA group), and face validity were investigated. Test-retest reliability was considered as well. Results: The relationship between the PASAT and digit memory span tests was moderate to strong in the control group (forward digit memory span test: r= 0.52, p< 0.0001; backward digit memory span test: r = 0.48, p< 0.0001). A strong relationship was found in IWA (forward digit memory span test: r= 0.72, p< 0.0001; backward digit memory span test: r= 0.53, p= 0.006). Also, strong testretest reliability (intraclass correlation= 0.95, p< 0.0001) was observed. Conclusion: According to our results, the PASAT is a valid and reliable test to assess working memory, particularly in IWA. It could be used as a feasible tool for clinical and research applications. PMID- 29445692 TI - Does smoking status affect cost of hospitalization? Evidence from three main diseases associated with smoking in Iran. AB - Background: Smoking is recognized as one of the main public health problems worldwide and is accounted for a high financial burden to healthcare systems and the society as a whole. This study was aimed at examining the effect of smoking status on cost of hospitalization among patients with lung cancer (LC), chronic obstructive pulmonary disease (COPD) and ischemic heart diseases (IHD) in Iran in 2014. Methods: A total of 1,271 patients (consisting of 415 LC, 427 COPD and 429 IHD patients) were included in the study. Data on age, sex, and insurance status, length of hospital stay and cost of hospitalization were extracted from the medical records of the patients. The smoking status of the patients was obtained through a telephone survey. A generalized linear model (GLM) was used to compare the costs of hospitalization of current, former and never smokers. The analysis was done using Stata v.12. Results: The mean+/-SD cost of hospitalization per patient was 45.6 +/- 41.8 million IR for current smokers, 34.8+/-23 million IR for former smokers and 27.6+/-24.6 million IR for never smokers, respectively. The findings indicated that the cost of hospitalization for current and former smokers was 65% and 26% in the unadjusted model and 35% and 24% in the adjusted model higher than for never smokers. Conclusion: The findings revealed that smoking drains a large hospital resource and imposes a high financial burden on the health system and the society. Therefore, efforts should focus on reducing the prevalence of smoking and the negative economic consequences of smoking. PMID- 29445691 TI - Study of Porphyromonas gingivalis in periodontal diseases: A systematic review and meta-analysis. AB - Background: The mouth cavity hosts various types of anaerobic bacteria including Porphyromonas gingivalis, which causes periodontal inflammatory diseases. P. gingivalis is a gram-negative oral anaerobe and is considered as a main etiological factor in periodontal diseases. Several studies have reported a relationship between P. gingivalis in individuals with periodontal diseases and a critical role of this bacterium in the pathogenesis of periodontal diseases. The present study aimed at estimating this probability using a meta-analysis. Methods: We searched several databases including PubMed, Scopus, Google Scholar, and Web of Science to identify case-control studies addressing the relationship between P. gingivalis with periodontal diseases. A total of 49 reports published from different countries from 1993 to 2014 were included in this study. I2 (heterogeneity index) statistics were calculated to examine heterogeneity. Data were analyzed using STATA Version 11. Results: After a detailed analysis of the selected articles, 49 case-control studies with 5924 individuals fulfilled the inclusion criteria for the meta-analysis. The healthy controls included 2600 healthy individuals with a Mean+/-SD age of 36.56+/-7.45 years. The periodontal diseases group included 3356 patients with a mean age of 43.62+/-8.35 years. There was a statistically significant difference between P. gingivalis in periodontal patients and healthy controls; 9.24 (95% CI: 5.78 to 14.77; P = 0.000). In the other word, there was a significant relationship between the presence of P. gingivalis and periodontal diseases. Conclusion: Analyzing the results of the present study, we found a strong association between the presence of P. gingivalis and periodontal diseases. This result suggests that another research is needed to further assess this subject. PMID- 29445693 TI - Antibacterial activity of amino- and amido- terminated poly (amidoamine)-G6 dendrimer on isolated bacteria from clinical specimens and standard strains. AB - Background: Nanoscale poly (amidoamine) dendrimers have been investigated for their biological demands, but their antibacterial activity has not been widely discovered. Thus, the sixth generation of poly (amidoamine) dendrimer (PAMAM-G6) was synthesized and its antibacterial activities were evaluated on Gram-negative bacteria; P. aeruginosa, E. coli, A. baumannii, S. typhimurium, S. dysenteriae, K. pneumoniae, P. mirabilis, and Gram-positive bacteria, and S.aureus and B. subtilis, which were isolated from different clinical specimens and standard strains of these bacteria. Methods: In this study, 980 specimens including urine (47%), blood (27%), sputum (13%), wounds (8%), and burns (5%) were collected from clinical specimens of 16 hospitals and clinics in city of Sabzevar, Iran. Then, the target bacteria were isolated and identified using standard methods. Minimum inhibitory concentration and minimum bactericidal concentrations against Gram positive and Gram-negative bacteria were determined according to guidelines described by clinical and laboratory standards institute (CLSI). Standard discs were prepared using 0.025, 0.25, 2.5, and 25 MUg/mL concentrations of PAMAM-G6 on Mueller-Hinton agar plates to determinate the zone of inhibition. The cytotoxicity of PAMAM-G6 dendrimer was evaluated in HCT116 cells by MTT assay. Results: The most important isolated bacteria were E. coli (23.65%), S. aureus (24.7%), P. aeruginosa (10.49%), B. subtilis (7.7%), S. typhimurium (8.87%), A. baumannii (7.02%), K. pneumoniae (7.1%), P. mirabilis (6.46%), and S. dysenteriae (3.6%). Moreover, it was found that poly (amidoamine)-G6 exhibited more antibacterial efficacy on standard strains than isolated bacteria from clinical samples (p<0.05). The cytotoxicity of PAMAM-G6 to the cells showed that cytotoxicity depended on the concentration level and exposure time. Conclusion: The PAMAM-G6 dendrimer showed a positive impact on the removal of dominant bacterial isolated from clinical specimens and standard strains. PMID- 29445694 TI - P-value: What is and what is not. AB - The misinterpretation and misuse of p-value have been increasing for decades. In March 2016, the American Statistical Association released a statement to warn about the use and interpretation of p-value. In this study, we provided a definition and discussion of pvalue and emphasized the importance of its accurate interpretation. PMID- 29445695 TI - Serum mannan-binding lectin in patients with pulmonary tuberculosis: Its lack of a relationship to the disease and response to treatment. AB - Background: Lectin pathway mediates complement activation, which is activated by many microorganisms. This study aimed at determining the serum levels of mannose binding lectin (MBL) in patients with pulmonary tuberculosis, assessing its relationship to antiuberculosis treatment response, and comparing them with a control group. Methods: This cross-sectional study was conducted on patients with pulmonary tuberculosis during 2012 and 2013 in South West of Iran. PPD-ST negative individuals were selected as controls from healthy relatives of patients. Serum MBL levels were measured using ELISA kit (Human MBL HK323, Hycultbiotech Company, Netherlands). All patients were followed- up for response to treatment. We applied Mann-Whitney and Fisher's exact tests and used SPSS Version 17 software for statistical analysis. Results: The study included 62 patients as the case group and 63 noninfected TB patients as the control group. The MBL (ng/mL) in patients with pulmonary tuberculosis (median = 1012) was significantly (p= 0.037) higher than that of the control group (median= 296.2). No significant difference was found in the MBL level (ng/mL) between patients with response to antituberculosis treatment (median= 1012) and patients with treatment failure (median= 798.9) (p= 0.84). Conclusion: MBL may be involved in the pathogenesis of tuberculosis and in the low values that are protective against tuberculosis, and it seems that it has no effect on the antituberculosis treatment response. PMID- 29445696 TI - Identifying training and informational components to develop a psoriasis self- management application. AB - Background: Psoriasis is a complex disease with lifelong emotional and social consequences for affected patients. It also reduces the patients' quality of life and requires a long-term management. Therefore, in addition to appropriate treatment of the disease, selfmanagement strategies to improve patient health and quality of life are essential. On the other hand, smartphone-based applications alter the way people interact with health care and public health systems. This study aimed at identifying training and informational components to develop a psoriasis self- management application. Methods: This descriptive-analytic study was conducted on 100 patients with psoriasis and 26 dermatologists who were selected randomly, using Morgan table. The data were collected using a researcher made questionnaire, which included demographic and clinical information, lifestyle training and management, and application capabilities in psoriasis self management. A group of experts and a test-retest method were used to confirm the validity and reliability of the questionnaire, respectively. Results: The mean scores for demographic and clinical information, lifestyle training and management, and application capabilities in self-management were 80.55%, 85.7%, and 88.8% from the patients' perspective, and 83.7%, 71%, and 75% from the specialists' viewpoint, respectively. Conclusion: Determining self-management components by patients as persons who are suffering from the disease and physicians as specialists in the field will be helpful in efficient psoriasis self-management. It is more likely that self-reliant patients, who are aware of the benefits and risks of their disease management application, will follow their treatment plan and pursue the management of their disease more seriously. PMID- 29445697 TI - Social accounting matrix and the effects of economic reform on health price index and household expenditures: Evidence from Iran. AB - Background: Socioeconomic indicators are the main factors that affect health outcome. Health price index (HPI) and households living costs (HLC) are affected by economic reform. This study aimed at examining the effect of subsidy targeting plan (STP) on HPI and HLC. Methods: The social accounting matrix was used to study the direct and indirect effects of STP. We chose 11 health related goods and services including insurance, compulsory social security services, hospital services, medical and dental services, other human health services, veterinary services, social services, environmental health services, laundry& cleaning and dyeing services, cosmetic and physical health services, and pharmaceutical products in the social accounting matrix to examine the health price index. Data were analyzed by the I-O&SAM software. Results: Due to the subsidy release on energy, water, and bread prices, we found that (i) health related goods and services groups' price index rose between 33.43% and 77.3%, (ii) the living cost index of urban households increased between 48.75% and 58.21%, and (iii) the living cost index of rural households grew between 53.51% and 68.23%. The results demonstrated that the elimination of subsidy would have negative effects on health subdivision and households' costs such that subsidy elimination increased the health prices index and the household living costs, especially among low income families. The STP had considerable effects on health subdivision price index. Conclusion: The elimination or reduction of energy carriers and basic commodities subsidies have changed health price and households living cost index. Therefore, the policymakers should consider controlling the price of health sectors, price fluctuations and shocks. PMID- 29445698 TI - The impact of computerized physician order entry on prescription orders: A quasi experimental study in Iran. AB - Background: One way to reduce medical errors associated with physician orders is computerized physician order entry (CPOE) software. This study was conducted to compare prescription orders between 2 groups before and after CPOE implementation in a hospital. Methods: We conducted a before-after prospective study in 2 intensive care unit (ICU) wards (as intervention and control wards) in the largest tertiary public hospital in South of Iran during 2014 and 2016. All prescription orders were validated by a clinical pharmacist and an ICU physician. The rates of ordering the errors in medical orders were compared before (manual ordering) and after implementation of the CPOE. A standard checklist was used for data collection. For the data analysis, SPSS Version 21, descriptive statistics, and analytical tests such as McNemar, chi-square, and logistic regression were used. Results: The CPOE significantly decreased 2 types of errors, illegible orders and lack of writing the drug form, in the intervention ward compared to the control ward (p< 0.05); however, the 2 errors increased due to the defect in the CPOE (p< 0.001). The use of CPOE decreased the prescription errors from 19% to 3% (p= 0.001), However, no differences were observed in the control ward (p<0.05). In addition, more errors occurred in the morning shift (p< 0.001). Conclusion: In general, the use of CPOE significantly reduced the prescription errors. Nonetheless, more caution should be exercised in the use of this system, and its deficiencies should be resolved. Furthermore, it is recommended that CPOE be used to improve the quality of delivered services in hospitals. PMID- 29445700 TI - Health care expenditure in the Islamic Republic of Iran versus other high spending countries. AB - Background: In all countries, health expenditures are a main part of government expenditure, and governments try to find policies and strategies to reduce this expenditure. Overall expenditure index has been raised 30 times during the past 20 years in Iran, while in the health sector, the growth in health expenditures index has been 71 times. The present study aimed at examining health care expenditure in the Islamic Republic of Iran versus other high spending countries. Methods: A comparative panel study was conducted in selected countries with the high mean of health expenditure per capita. Data were collected from the WORLD BANK. Out- of- pocket (OOP), health expenditure per capita, public and private health expenditure, and total health expenditure were compared among the selected counties. Results: Iran has the lowest health expenditure per capita compared to other countries and the USA has the highest health expenditures per capita. In Iran, out- of- pocket expenditure, with more than 50%, was the most cost, while in Luxembourg it was the least cost during 2004 to 2014, with less than 12%. Conclusion: Our findings revealed that politicians and health care executives should find a stable source to finance the health system. Stable sources of financing lead to having a steady trend in health expenditure. PMID- 29445699 TI - Out-of-pocket and informal payments in Iran's health care system: A systematic review and meta-analysis. AB - Background: Out-of-pocket and informal payments are considered as 2 most important topics for equity in health care financing. Therfore, this study was conducted to systematically review and meta-analyze the status of these payments in Iran's health care system. Methods: Required data were collected through searching the following key terms: "Unofficial", "Informal Payment", "Iran", "Health Financing", "Health expenditure", and "Out-of-pocket" on Scopus, PubMed, IranMedex, SID, and Google Scholar databases. After extracting and screening previous studies, data were collected from the articles using PRISMA pattern. To perform the metaanalysis, Comprehensive Meta-Analysis (CMA: 2) software was used. Results: A total of 15 studies were entered in this review. Overall, the rate of out-of-pocket payments was estimated to be 50% (95% CI: 45-57%). A significant correlation was found between gender and the rate of out-of-pocket payments (p<=0.05). Moreover, the overall rate of informal payments was found to be 35%. Most of the informal payments were in form of cash, and the main reasons for informal payments were appreciating the staff and medical team as well as requests made by the hospital staff. Length of stay, marital status, employment status, income, and insurance coverage were key factors in the field of informal payments. Conclusion: According to the results of the present study, out-of pocket and informal payments are more prevalent in Iran. Considering the negative effects of these payments on the health care system, it is of prime importance to implement extensive interventions to reduce or even prevent these payments. PMID- 29445701 TI - The impact of the learning contract on self-directed learning and satisfaction in nursing students in a clinical setting. AB - Background: The most important responsibilities of an education system are to create self-directed learning opportunities and develop the required skills for taking the responsibility for change. The present study aimed at determining the impact of a learning contract on self-directed learning and satisfaction of nursing students. Methods: A total of 59 nursing students participated in this experimental study. They were divided into six 10-member groups. To control the communications among the groups, the first 3 groups were trained using conventional learning methods and the second 3 groups using learning contract method. In the first session, a pretest was performed based on educational objectives. At the end of the training, the students in each group completed the questionnaires of self-directed learning and satisfaction. The results of descriptive and inferential statistical methods (dependent and independent t tests) were presented using SPSS. Results: There were no significant differences between the 2 groups in gender, grade point average of previous years, and interest toward nursing. However, the results revealed a significant difference between the 2 groups in the total score of self-directed learning (p= 0.019). Although the mean satisfaction score was higher in the intervention group, the difference was not statistically significant. Conclusion: This study suggested that the use of learning contract method in clinical settings enhances self directed learning among nursing students. Because this model focuses on individual differences, the researcher highly recommends the application of this new method to educators. PMID- 29445702 TI - Validity and reliability of Persian version of Listening Styles Profile-Revised (LSP- R) in Iranian students. AB - Background: Individuals' listening styles differs based on their characters, professions and situations. This study aimed to assess the validity and reliability of Listening Styles Profile- Revised (LSP- R) in Iranian students. Methods: After translating into Persian, LSP-R was employed in a sample of 240 medical and nursing Persian speaking students in Iran. Statistical analysis was performed to test the reliability and validity of the LSP-R. Results: The study revealed high internal consistency and good test-retest reliability for the Persian version of the questionnaire. The Cronbach's alpha coefficient was 0.72 and intra-class correlation coefficient 0.87. The means for the content validity index and the content validity ratio (CVR) were 0.90 and 0.83, respectively. Exploratory factor analysis (EFA) yielded a four-factor solution accounted for 60.8% of the observed variance. Majority of medical students (73%) as well as majority of nursing students (70%) stated that their listening styles were task oriented. Conclusion: In general, the study finding suggests that the Persian version of LSP-R is a valid and reliable instrument for assessing listening styles profile in the studied sample. PMID- 29445703 TI - Critical appraisal of fundamental items in approved clinical trial research proposals in Mashhad University of Medical Sciences. AB - Background: Writing, designing, and conducting a clinical trial research proposal has an important role in achieving valid and reliable findings. Thus, this study aimed at critically appraising fundamental information in approved clinical trial research proposals in Mashhad University of Medical Sciences (MUMS) from 2008 to 2014. Methods: This cross-sectional study was conducted on all 935 approved clinical trial research proposals in MUMS from 2008 to 2014. A valid and reliable as well as comprehensive, simple, and usable checklist in sessions with biostatisticians and methodologists, consisting of 11 main items as research tool, were used. Agreement rate between the reviewers of the proposals, who were responsible for data collection, was assessed during 3 sessions, and Kappa statistics was calculated at the last session as 97%. Results: More than 60% of the research proposals had a methodologist consultant, moreover, type of study or study design had been specified in almost all of them (98%). Appropriateness of study aims with hypotheses was not observed in a significant number of research proposals (585 proposals, 62.6%). The required sample size for 66.8% of the approved proposals was based on a sample size formula; however, in 25% of the proposals, sample size formula was not in accordance with the study design. Data collection tool was not selected appropriately in 55.2% of the approved research proposals. Type and method of randomization were unknown in 21% of the proposals and dealing with missing data had not been described in most of them (98%). Inclusion and exclusion criteria were (92%) fully and adequately explained. Moreover, 44% and 31% of the research proposals were moderate and weak in rank, respectively, with respect to the correctness of the statistical analysis methods. Conclusion: Findings of the present study revealed that a large portion of the approved proposals were highly biased or ambiguous with respect to randomization, blinding, dealing with missing data, data collection tool, sampling methods, and statistical analysis. Thus, it is essential to consult and collaborate with a methodologist in all parts of a proposal to control the possible and specific biases in clinical trials. PMID- 29445704 TI - Prevalence of depression in people with HIV and AIDS in Iran: A systematic review. AB - Background: Depression is the most common mental disorder in individuals with HIV and AIDS (PLWHA), and comorbidity with depression exacerbates the disease. Several studies have estimated the prevalence of depression in HIV and AIDS patients so far, but there is no consensus about the prevalence of depression among these patients. Thus, we aimed at estimating the overall prevalence of depression among Iranian PLWHA. Methods: The international and national databases including Web of Science, Scopus, Medline, Science Direct, MagIran, Scientific Information Database (SID), IranMedex, and Medlib were searched until June 2016. The quality of included studies was assessed using Newcastle-Ottawa Scale. Results: Out of 591 references, 9 cross-sectional studies met the eligibility criteria and were included in the review. The lowest and highest reported prevalence of depression among people with HIV was 22% (95% CI: (11, 33)) and 76% (95% CI: (71, 81)), respectively. Prevalence of depression in people with HIV in the north, west, and south of Iran was 45% (95% CI: (23, 67)), 30% (95% CI: (15, 45)), and 56% (95% CI: (35, 77)), respectively. Prevalence of depression among addict and non-addict patients was 25% (95% CI: (21, 30)) and 58% (95% CI: (40, 77)), respectively. Conclusion: According to the results of this systematic review, the prevalence of depression is considerable among Iranian PLWHA. Prevalence in the southern regions of Iran is more than the western and northern regions of Iran. This evidence may be useful for Iranian health policymakers to design suitable preventive and therapeutic interventions in PLWHA to prevent and control depression among these people in Iran. PMID- 29445705 TI - Evidence- based medicine performance among health care providers in Iranian hospitals: A nationwide survey. AB - Background: Evidence- Based Medicine (EBM) refers to the ability and skill in the use and integration of the best evidence obtained from repeatable bias-free clinical trials with the patients' preferences and conditions. Considering this fact that few large-scale studies have been done in this field in Iran, the present study aimed at comprehensively reviewing the status of EBM performance among health care providers in Iranian hospitals. Methods: This cross-sectional study was conducted during 2014 and 2015. Study participants consisted of 2800 health care providers (physicians, nurses, midwives, and paramedical personnel) in active hospitals in Iran. Data collection tool was a self-made questionnaire. Content validity of the questionnaire was improved by comments of 10 experts. The reliability of the questionnaire was assessed using test-retest method (alpha= 0.85). Results: The results revealed that only 12.7% and 15.8% of the participants were highly familiar with EBM databases and terminologies, respectively. Most participants believed that EBM-related workshops and practical involvement in EBM-related programs and activities can have a more effect on the improvement of EBM performance. Most participants had a positive view of the EBM. About 47% of the participants reported that their EBM knowledge and skills is high. Among the demographic variables, there were only significant relationships between work experience and attitude, gender and attitudes, and between knowledge and skills (p<0.05). Conclusion: According to the results of the present study, it seems that holding EBM-related workshops and practical participation in EBP related programs and activities as well as improving facilities such as manpower, equipment, and access can have a significant effect on improving EBM- related activities. PMID- 29445706 TI - Estimation of economic burden of preterm and premature births in Iran. AB - Background: Tremendous difficulties are imposed on families with preterm and premature babies, both at birth and during their lifetime. The present study aimed at evaluating the potential economic impact of preterm and premature birth in Iran. Methods: In this descriptive cross-sectional study (2014-2015), we studied preterm and premature newborns, who have been subjected to hospitalization in Ali-Asghar hospital. We followed social perspective to estimate the economic consequences of preterm and premature birth in 3 categories of direct medical, direct non-medical, and indirect costs. Required data were collected from documents in the NICU, and studying medical records, and interviewing their parents. Data were analyzed by Microsoft Excel. Results: Direct medical, direct non-medical and indirect affairs were 84%, 6%, and 10% of the total cost, respectively. The estimated social costs were 373, 529, 189; 508, 774, 181; and 529, 481, 996 US dollars (according to their corresponding incidence of 5.8%, 7.9%, and 9.9%). We also found that 75% of the direct medical costs of initial hospitalization were due to intensive care beds. Conclusion: The economic burden of preterm and premature birth in Iran is considerable and to decrease the costs, it is necessary to implement preventive programs for preterm and premature newborns and to provide management care and support for families dealing with this problem. PMID- 29445707 TI - Patient waiting time in hospital emergency departments of Iran: A systematic review and meta-analysis. AB - Background: Waiting time in emergency department is a key indicator in measuring the quality of hospital services and has a significant impact on patient satisfaction The purpose of this study was to conduct a systematic review and meta-analysis of the patients' waiting time in hospital emergency departments in Iran. Methods: Data were collected from databases of Web of Science, Embase, PubMed, Scopus, Google scholar, SID, and Iran Medex using the following key words: "emergency ward", "emergency room", "waiting time", " time delay", "first visit", "first treatment" , "emergency department", "Iran", and their Persian equivalents. The timeframe of 2000 to 2016 was selected to search the articles. CMA 2 (Comprehensive Meta-Analysis) software was used in this meta-analysis. Results: A total of 236 articles were extracted from databases and other sources, and finally 17 articles were included in the analysis. In total, waiting time in different parts of the emergency department was measured for 15 943 patients. Mean+/-SD waiting time was 5.9 +/- 0.6 minutes from the arrival to the first visit by a physician, it was 45 +/- 5 minutes between the first visit and the first therapeutic steps, 94+/- 33.9 minutes between referring to the laboratory and receiving the result, 23.2 +/- 3 minutes between referring to the radiology and receiving the result, and 32.2 +/- 7 minutes between referring to ECG and receiving the result; moreover, waiting time for the first specialist consultation was 99.3 +/- 32.8 minutes. Conclusion: The results demonstrated that waiting time in the emergency rooms of Iranian hospitals was higher than the national and international standards. According to the high rate of heterogeneity in the results and probability of publication bias, we highly recommend that readers use the results of this study and pay sufficient attention to this issue. PMID- 29445708 TI - Roles of triglyceride and phosphate in atherosclerosis of diabetic hemodialysis patients. AB - Background: A growing number of patients with End-Stage Renal Disease (ESRD) are undergoing long-term hemodialysis (HD). HD needs a vascular access (VA) and complications of VA account for a sizable proportion of its costs. One of the important cardiovascular diseases (CVD) is atherosclerosis, which is a major cause of premature deaths in the world. So, it is essential to find the risk factors to treat them before they cause an obvious CVD. Methods: We analyzed data from 174 ESRD patients who were candidate for Arterio Venous Fistula (AVF) creation from April 2008 to March 2009 in Hasheminejad Kidney Center by convenient sampling. X-ray images were used and C 4.5 algorithm of data mining techniques revealed the roles of two risk factors for atherosclerosis of diabetic ESRD patients. Pearson coefficient was also used to measure the correlation between the parameters. Results: Diabetic patients had significantly more calcified arteries in their forearm X-ray than other patients (p<0.001). Occurrence of atherosclerotic CVD in diabetic HD patients has an adverse relation compared with the controlled levels of their plasma levels of Triglyceride (TG) and Phosphorus. We found an inverse effect of TG and phosphorus plasma levels on the atherosclerotic involvement of radial and ulnar arteries in diabetic HD patients. We observed that the prevalence of radial and ulnar arteries calcification in these patients is lower when they have higher plasma levels of TG and phosphorous. Conclusion: This study investigates the role of high plasma levels of TG and phosphorous in the development of atherosclerosis in diabetic HD patients. Although many studies showed that hypertriglyceridemia plays a promoting role in the development of CVD, our study also found an inverse effect of plasma levels of TG on the atherosclerotic involvement of radial and ulnar arteries in diabetic patients, and therefore our results support this suspicion that hypertriglyceridemia plays a significant role in developing atherosclerosis.

PMID- 29445709 TI - Association between the circulating leptin levels and the biomarkers of oxidative stress and inflammation among Iranian overweight and obese adults. AB - Background: Oxidative stress in obese people is an important pathogenic mechanism of an obesity-associated metabolic syndrome. We evaluated the association between circulating leptin levels with biomarkers of oxidative stress in overweight and obese participants. Methods: This study was performed on 189 overweight and obese people aged 18-60 years old. Serum leptin, superoxide dismutase (SOD), high sensitivity C-reactive protein (hs-CRP), homocysteine (Hcy), thiobarbituric acid reactive substances (TBARS) and amyloid A (SAA) concentrations were measured. Pearson correlation and multiple linear regressions were used to assess the relationships. Results: We found that among the biomarkers of oxidative stress and inflammation in participants, serum hs-CRP and SAA were positively correlated with BMI (beta=0.003, P<0.001 and beta=7.83, P<0.001, respectively). This relationship remained significant even after controlling other oxidative stress and inflammatory indicators (beta=0.003, p<0.001 for hs-CRP), but this association disappeared for SAA. In addition, serum hs-CRP was positively correlated with leptin (beta=0.001, p=0.003). Regression analysis showed that there was no association between serum Hcy, SAA, TBARS and SOD with serum leptin concentrations Conclusion: Overall, the current study demonstrated that serum hs CRP and SAA levels were independently correlated with BMI. Furthermore, serum hs CRP was positively correlated with leptin. Focusing on such strategies may lead to promises for alleviating obesity and its co-morbidities. PMID- 29445712 TI - Radioprotective Effects of Sulfur-containing Mineral Water of Ramsar Hot Spring with High Natural Background Radiation on Mouse Bone Marrow Cells. AB - Background: We intend to study the inhibitory effect of sulfur compound in Ramsar hot spring mineral on tumor-genesis ability of high natural background radiation. Objective: The radioprotective effect of sulfur compounds was previously shown on radiation-induced chromosomal aberration, micronuclei in mouse bone marrow cells and human peripheral lymphocyte. Ramsar is known for having the highest level of natural background radiation on Earth. This study was performed to show the radioprotective effect of sulfur-containing Ramsar mineral water on mouse bone marrow cells. Method: Mice were fed three types of water (drinking water, Ramsar radioactive water containing sulfur and Ramsar radioactive water whose sulfur was removed). Ten days after feeding, mice were irradiated by gamma rays (0, 2 and 4 Gy). 48 and 72 hours after irradiating, mice were killed and femurs were removed. Frequency of micronuclei was determined in bone marrow erythrocytes. Results: A significant reduction was shown in the rate of micronuclei polychromatic erythrocyte in sulfur-containing hot spring water compared to sulfur-free water in hot spring mineral water. Gamma irradiation induced significant increases in micronuclei polychromatic erythrocyte (MNPCE) and decreases in polychromatic erythrocyte/polychromatic erythrocyte + normochromatic erythrocyte ratio (PCEs/PCEs+NCEs) (P < 0.001) in sulfur-containing hot spring water compared to sulfur-free hot spring mineral water. Also, apparently there was a significant difference between drinking water and sulfur-containing hot spring water in micronuclei polychromatic erythrocyte and polychromatic erythrocyte/polychromatic erythrocyte+ normochromatic erythrocyte ratio. Conclusion: The results indicate that sulfur-containing mineral water could result in a significant reduction in radiation-induced micronuclei representing the radioprotective effect of sulfur compounds. PMID- 29445711 TI - In-vitro Study of Photothermal Anticancer Activity of Carboxylated Multiwalled Carbon Nanotubes. AB - Background and Objective: Multi-walled Carbon Nano Tubes (MWCNTs) as an important element of nanosciences have a remarkable absorption in the region of NIR window (650-900 nm) which can overcome the limitations of deep treatment in photothermal therapy. To disperse MWCNTs in water, it is proposed to attach carboxylated functional group (-COOH) to MWCNTs in order to increase dispersivity in water. Materials and Methods: A stable suspension of MWCNTs-COOH with different concentrations (from 2.5 to 500 MUg/ml) was prepared. Then, they were compared for their ability to increase temperature in the presence of 810 nm laser irradiation and through a wide range of radiation time (from 20 to 600 s) and three laser powers (1.5, 2 and 2.5 w). The temperature rise was recorded real time every 20 seconds by a precise thermometer. Results: Absorption spectrum of MWCNTs-COOH suspension was remarkably higher than water in a wavelength range of 200 to 1100 nm. For example, using the concentrations of 2.5 and 80 MUg/ml of MWCNTs-COOH suspension caused a temperature elevation 2.35 and 9.23 times compared to water, respectively, upon 10 min laser irradiation and 2.5 w. Moreover, this predominance can be observed for 1.5 and 2 w radiation powers, too. Our findings show that the maximum of temperature increase was obtained at 80 MUg/ml concentration of MWCNT-COOH suspension for three powers and through all periods of exposure time. Our results show that the minimum required parameters for a 5 degrees C temperature increase (a 5 degrees C temperature increase causes cell death) were achieved through 2.5 w, 28 MUg/ml concentration and 20 second irradiation time in which both concentration and radiation times were relatively low. Conclusion: Our results showed that MWCNTs-COOH can be considered as a potent photothermal agent in targeted therapies. New strategies must be developed to minimize the concentration, irradiation time and radiation power used in experiments. PMID- 29445713 TI - Effects of Laser Physical Parameters on Lesion Size in Retinal Photocoagulation Surgery: Clinical OCT and Experimental Study. AB - Introduction: The aim of the present study was to determine burn intensity in retinal laser photocoagulation based on laser parameters; wavelength, power, beam size and pulse duration, using Optical Coherence Tomography (OCT), fundus camera, physical eye model and computer simulation in a clinical study. Materials and Methods: Participants were 10 adult patients between 50-80 years with proliferative diabetic retinopathy. A multicolor-photo coagulator with 532 nm green and 672 nm red for retina photocoagulation in diabetic retinopathy was used to investigate the participants. Lesion size was measured for spot sizes 50 and 100 MUm, with 100 and 150 mW laser power, and pulse duration 50 and 100 ms by OCT. Artificial eye and Zemax-optical design software were used with the same laser parameters. Results: Appearance of OCT and fundus images showed direct relationship between retina burn size and lesion intensity with exposure time and power and also reverse relationship with laser spot size. Compared to red wavelength, burn size and lesion intensity increased in green wavelength. On the other hand, results from physical eye model were the same as clinical examination shown. Laser spot size in retina with Zemax simulation demonstrated that red wavelength was greater than green one. Conclusion: This study showed shorter pulses provide decrease in duration of laser surgery with significantly reduced pain. Results and calculations described in this article can help clinicians adjusting the required total coagulated area, the number of lesions and pattern density. PMID- 29445714 TI - Brain Volume Estimation Enhancement by Morphological Image Processing Tools. AB - Background: Volume estimation of brain is important for many neurological applications. It is necessary in measuring brain growth and changes in brain in normal/abnormal patients. Thus, accurate brain volume measurement is very important. Magnetic resonance imaging (MRI) is the method of choice for volume quantification due to excellent levels of image resolution and between-tissue contrast. Stereology method is a good method for estimating volume but it requires to segment enough MRI slices and have a good resolution. In this study, it is desired to enhance stereology method for volume estimation of brain using less MRI slices with less resolution. Methods: In this study, a program for calculating volume using stereology method has been introduced. After morphologic method, dilation was applied and the stereology method enhanced. For the evaluation of this method, we used T1-wighted MR images from digital phantom in BrainWeb which had ground truth. Results: The volume of 20 normal brain extracted from BrainWeb, was calculated. The volumes of white matter, gray matter and cerebrospinal fluid with given dimension were estimated correctly. Volume calculation from Stereology method in different cases was made. In three cases, Root Mean Square Error (RMSE) was measured. Case I with T=5, d=5, Case II with T=10, D=10 and Case III with T=20, d=20 (T=slice thickness, d=resolution as stereology parameters). By comparing these results of two methods, it is obvious that RMSE values for our proposed method are smaller than Stereology method. Conclusion: Using morphological operation, dilation allows to enhance the estimation volume method, Stereology. In the case with less MRI slices and less test points, this method works much better compared to Stereology method. PMID- 29445715 TI - Detection of Ultraweak Photon Emission (UPE) from Cells as a Tool for Pathological Studies. AB - Objective: It is well-known that all living cells emit ultra-weak photon emission (UPE), which is due to byproducts of chemical reactions in cell metabolisms. It has been shown that Reactive Oxygen Species (ROS) in the cells enhances the UPE intensity. The magnitude of such UPE is extremely weak (i.e. a few to 103 photons/ (sec.cm22)), and the detection of such ultra-weak signals is hardly possible via sensitive instruments like photomultiplier tube (PMT) that can detect single photons. Materials and Methods: H2O2 factor with various concentrations was applied on the HT-29 cells to generate ROS. H2O2 concentrations were so low to be nondestructive to the cells. Then, the effect of ROS generation on UPE intensity was investigated. PMT was used to detect UPE from HT-29 cells. Results: The topical application of H2O2 was significantly different (P < 0.05) in comparison with HT-29 cells without H2O2 at a concentration of 1mM in 5 min detection time. The integrated UPE in the presence of H2O2 at concentration of 3mM was significantly higher (P < 0.05) than the integrated UPE in other groups at the same detection time. The difference between the concentrations of 3mM and 4mM was not significant (P > 0.01) for integrated UPE in the cell groups in the presence of H2O2. Conclusion: The results show that the recorded UPE from HT-29 cells increased with the topical application of exogenous ROS inducer. As a result, UPE can be used as a non-invasive technique for monitoring ROS in cells. PMID- 29445716 TI - A Study on Performance and Safety Tests of Defibrillator Equipment. AB - Introduction: Nowadays, more than 10,000 different types of medical devices can be found in hospitals. This way, medical electrical equipment is being employed in a wide variety of fields in medical sciences with different physiological effects and measurements. Hospitals and medical centers must ensure that their critical medical devices are safe, accurate, reliable and operational at the required level of performance. Defibrillators are critical resuscitation devices. The use of reliable defibirillators has led to more effective treatments and improved patient safety through better control and management of complications during Cardiopulmonary Resuscitation (CPR). Materials and Methods: The metrological reliability of twenty frequent use, manual defibrillators in use ten hospitals (4 private and 6 public) in one of the provinces of Iran according to international and national standards was evaluated. Results: Quantitative analysis of control and instrument accuracy showed the amount of the obtained results in many units are critical which had less value over the standard limitations especially in devices with poor battery. For the accuracy of delivered energy analysis, only twelve units delivered acceptable output values and the precision in the output energy measurements especialy in weak battry condition, after activation of discharge alarm, were low. Conclusion: Obtained results indicate a need for new and severe regulations on periodic performance verifications and medical equipment quality control program especially for high risk instruments. It is also necessary to provide training courses on the fundumentals of operation and performane parameters for medical staff in the field of meterology in medicine and how one can get good accuracy results especially in high risk medical devices. PMID- 29445717 TI - Acceptance of Health Information Technologies, Acceptance of Mobile Health: A Review Article. AB - Background: Mobile health is one of the new technologies for the utilization of health information. For its successful implementation as well as any other system, we must primarily measure the adoption and use of its factors. The purpose of this study was to systematically investigate published articles about the factors affecting the adoption of mobile health and categorizing the factors affecting the adoption of this system. Methods: This study is a comprehensive review done by searching major databases such as Google Scholar, Emerald, Science Direct, Iran Medex, SID, Magiran, Pub med, etc. In addition, we use Mobile, mobile Health + adoption, mobile Health + TAM, Health + TAM keywords in the range of 2004 to 2015. Results: Among the studies that use information technology theories to survey the factors affecting the adoption of mobile health, TAM model was used more than other models. Factors such as perceived ease of use, perceived usefulness and facilitating condition form TUATU are the most effective in the adoption of mobile health. Conclusion: Results showed that by considering factors such as perceived ease of use, perceived usefulness and facilitating condition can increase the adoption of mobile health system. Consequently, these factors are recommended to be considered in planning to run systems. PMID- 29445718 TI - Designing and Developing Automatic Trolley for Washing and Dressing the Wounds. AB - Introduction: Many items are needed for dressing including sterile dressing set, antiseptic and washing solutions, leucoplast tape, waste bin for infectious garbage, waste bin for noninfectious garbage, safe disposal trash for sharp cutting instruments, bedpan and sometimes drugs. All the items are laid out on a simple wheeled trolley. The multiplicity of items together with problems in placing tools on trolley, forgetting some items, disturbing sterile condition, falling and damaging equipment and the need for at least two people for each procedure, all are the reasons to design and develop Automatic Trolley for Washing and Dressing the Wounds. Material and Method: To develop a mobile unit which meets our needs for dressing, the trolley patents registered in America and different companies were evaluated as well as the materials and methods used while dressing were considered. Results: Automatic Trolley for Washing and Dressing the Wounds was designed and developed. It comprises the followings: drawer, waste bin for infectious garbage, waste bin for noninfectious garbage, shelves for serum and betadine solution, serum stand, peristaltic pump, flexible tube for connecting serum, a place for bedpan, foot pedal for serum flow, two eye sensor chambers for solution betadine and scrub, an auxiliary work surface. Conclusion: Due to the usual requirements for dressing, we have designed an equipped mobile unit which covers all the objectives of dressing and increases the speed of procedure. Moreover, due to the contrived equipment on the trolley, procedures are done quickly and second person is not required to assist. Automatic Trolley for Washing and Dressing the Wounds is made up of stainless steel which could be mass housing and commercializing which would play a deserving role in improving the fundamentals of health care and wound treatment.

PMID- 29445721 TI - Young Adults' Selection and Use of Dependent Coverage under the Affordable Care Act. AB - The dependent coverage expansion under the Affordable Care Act (ACA) required health insurance policies that cover dependents to offer coverage for policyholder' children up to age 26. It has been well documented that the provision successfully reduced the uninsured rate among the young adults. However, less is known about whether dependent coverage crowded out other insurance types and whether young adults used dependent coverage as a fill-in-the gap short-term option. Using data from the Survey of Income and Program Participation 2008 Panel, the paper assesses dependent coverage uptake and duration before and after the ACA provision among young adults aged 19-26 versus those aged 27-30. Regressions for additional coverage outcomes were also performed to estimate the crowd-out rate. It was found that the ACA provision had a significant positive impact on dependent coverage uptake and duration. The estimated crowd-out rate ranges from 27 to 42%, depending on the definition. Most dependent coverage enrollees used the coverage for 1 or 2 years. Differences in dependent coverage uptake and duration remained among racial groups. Less healthy individuals were also less likely to make use of dependent coverage. PMID- 29445722 TI - Genetic Testing between Private and Public Interests: Some Legal and Ethical Reflections. AB - In Europe, there is a wide variety of genetic tests that various private companies offer to patients or to consumers. More and more people have become curious about their genetic predisposition and susceptibility. Most public health care systems, however, are not adequately prepared for responding to these new demands and to the results of these genetic tests as, quite often, there is no available therapy for the identified genetic condition. This discrepancy between the newly emerging expectations and the insufficient responses contributes to a further rift between the public and private sectors of health care. Individual genetic test results may also trigger the need for personalized medicine and may open up a competition between the two fields in offering further genetic tests and medical exams. Pro-active patients may need a different kind of information on genetic tests and their implications. In this context, how should the public health system deal with the challenges of private testing? Will private genetic testing transform health care from a solidarity-based system to an individualistic one? In this paper, I would like to explore the emerging legal and ethical issues related to genetic testing and the relevant legal framework that has developed so far. In the conclusion, I will examine the possibilities of further legal development. PMID- 29445723 TI - Cord Care Practices: A Perspective of Contemporary African Setting. AB - Background: Cord care is the series of steps applied in handling of the umbilical cord after delivery of the new born. Globally, an estimated 4 million deaths occur annually within the first 4 weeks of life and 1.5 million of these deaths are attributable to infections. In Nigeria, studies have reported umbilical cord infections accounting for between 10 and 19% of neonatal admissions and resultant estimated 30-49% neonatal deaths. Hence, this study was conducted to assess the knowledge and practice of cord care within a contemporary setting. Methodology: This was a cross-sectional study conducted among 324 mothers of children less than 59 months using a multistage sampling technique and SSPS version 20 was used for data analysis. Crude and adjusted odds ratios as well as 95% confidence interval were used in this study with a P-value of <=0.05 considered statistically significant. Results: The mean age of the mothers in the study was 27.5 +/- 6 years with majority of them having good overall knowledge and practice of cord care. Factors such residence in rural community (AOR = 0.26; 95% CI = 0.0915-0.7230) and heath facility delivery (AOR = 7.0; 95% CI = 4.7877-9.3948) were predictors of cord care practices. Conclusion: This study has brought to light the level of cord care practices with health facility delivery, place of residence, and knowledge of cord care as its determinants. PMID- 29445720 TI - Application of Single-Nucleotide Polymorphism-Related Risk Estimates in Identification of Increased Genetic Susceptibility to Cardiovascular Diseases: A Literature Review. AB - Background: Although largely preventable, cardiovascular diseases (CVDs) are the biggest cause of death worldwide. Common complex cardiovascular disorders (e.g., coronary heart disease, hypertonia, or thrombophilia) result from a combination of genetic alterations and environmental factors. Recent advances in the genomics of CVDs have fostered huge expectations about future use of susceptibility variants for prevention, diagnosis, and treatment. Our aim was to summarize the latest developments in the field from a public health perspective focusing on the applicability of data on single-nucleotide polymorphisms (SNPs), through a systematic review of studies from the last decade on genetic risk estimating for common CVDs. Methods: Several keywords were used for searching the PubMed, Embase, CINAHL, and Web of Science databases. Recent advances were summarized and structured according to the main public health domains (prevention, early detection, and treatment) using a framework suggested recently for translational research. This framework includes four recommended phases: "T1. From gene discovery to candidate health applications; T2. From health application to evidence-based practice guidelines; T3. From evidence-based practice guidelines to health practice; and T4. From practice to population health impacts." Results: The majority of translation research belongs to the T1 phase "translation of basic genetic/genomic research into health application"; there are only a few population-based impacts estimated. The studies suggest that an SNP is a poor estimator of individual risk, whereas an individual's genetic profile combined with non-genetic risk factors may better predict CVD risk among certain patient subgroups. Further research is needed to validate whether these genomic profiles can prospectively identify individuals at risk to develop CVDs. Several research gaps were identified: little information is available on studies suggesting "Health application to evidence-based practice guidelines"; no study is available on "Guidelines to health practice." It was not possible to identify studies that incorporate environmental or lifestyle factors in the risk estimation. Conclusion: Currently, identifying populations having a larger risk of developing common CVDs may result in personalized prevention programs by reducing people's risk of onset or disease progression. However, limited evidence is available on the application of genomic results in health and public health practice.

PMID- 29445725 TI - A Polyoxoniobate/g-C3N4 Nanoporous Material with High Adsorption Capacity of Methylene Blue from Aqueous Solution. AB - A polyoxoniobate/g-C3N4 nanoporous material with functional groups has been synthesized by using carbon nitride (g-C3N4) and hexaniobate (K8Nb6O19.10H2O, abbreviated as NbO) as precursors. The structure and compositions of the as prepared nanomaterials were characterized by XRD, FT-IR, FESEM, TEM, and XPS. These two kinds of materials interact with each other forming a hybrid composite, which can be used as an adsorbent for removing a cationic dye (methylene blue, MB) from wastewater with excellent adsorption capacity. Furthermore, parameters that can affect adsorption process including initial dye concentration, pH and temperature were investigated by bath adsorption experiments. The results indicated that the maximum adsorption capacity of NbO/g-C3N4 can reach up to 373.1 mg g-1. Moreover, the equilibrium experiment data fitted Langmuir isotherm well and the adsorption kinetics showed that the pseudo second order model can satisfyingly described MB adsorption kinetics. The thermodynamic analysis indicated that the adsorption was endothermic and spontaneous.

PMID- 29445727 TI - Molecular Features Underlying Selectivity in Chicken Bitter Taste Receptors. AB - Chickens sense the bitter taste of structurally different molecules with merely three bitter taste receptors (Gallus gallus taste 2 receptors, ggTas2rs), representing a minimal case of bitter perception. Some bitter compounds like quinine, diphenidol and chlorpheniramine, activate all three ggTas2rs, while others selectively activate one or two of the receptors. We focus on bitter compounds with different selectivity profiles toward the three receptors, to shed light on the molecular recognition complexity in bitter taste. Using homology modeling and induced-fit docking simulations, we investigated the binding modes of ggTas2r agonists. Interestingly, promiscuous compounds are predicted to establish polar interactions with position 6.51 and hydrophobic interactions with positions 3.32 and 5.42 in all ggTas2rs; whereas certain residues are responsible for receptor selectivity. Lys3.29 and Asn3.36 are suggested as ggTas2r1 specificity-conferring residues; Gln6.55 as ggTas2r2-specificity-conferring residue; Ser5.38 and Gln7.42 as ggTas2r7-specificity conferring residues. The selectivity profile of quinine analogs, quinidine, epiquinidine and ethylhydrocupreine, was then characterized by combining calcium-imaging experiments and in silico approaches. ggTas2r models were used to virtually screen BitterDB compounds. ~50% of compounds known to be bitter to human are likely to be bitter to chicken, with 25, 20, 37% predicted to be ggTas2r1, ggTas2r2, ggTas2r7 agonists, respectively. Predicted ggTas2rs agonists can be tested with in vitro and in vivo experiments, contributing to our understanding of bitter taste in chicken and, consequently, to the improvement of chicken feed. PMID- 29445728 TI - Radiation-Induced Cardiovascular Disease: Mechanisms and Importance of Linear Energy Transfer. AB - Radiation therapy (RT) in the form of photons and protons is a well-established treatment for cancer. More recently, heavy charged particles have been used to treat radioresistant and high-risk cancers. Radiation treatment is known to cause cardiovascular disease (CVD) which can occur acutely during treatment or years afterward in the form of accelerated atherosclerosis. Radiation-induced cardiovascular disease (RICVD) can be a limiting factor in treatment as well as a cause of morbidity and mortality in successfully treated patients. Inflammation plays a key role in both acute and chronic RICVD, but the underling pathophysiology is complex, involving DNA damage, reactive oxygen species, and chronic inflammation. While understanding of the molecular mechanisms of RICVD has increased, the growing number of patients receiving RT warrants further research to identify individuals at risk, plans for prevention, and targets for the treatment of RICVD. Research on RICVD is also relevant to the National Aeronautics and Space Administration (NASA) due to the prevalent space radiation environment encountered by astronauts. NASA's current research on RICVD can both contribute to and benefit from concurrent work with cell and animal studies informing radiotoxicities resulting from cancer therapy. This review summarizes the types of radiation currently in clinical use, models of RICVD, current knowledge of the mechanisms by which they cause CVD, and how this knowledge might apply to those exposed to various types of radiation. PMID- 29445729 TI - Brucella Antibodies in Alaskan True Seals and Eared Seals-Two Different Stories. AB - Brucella pinnipedialis was first isolated from true seals in 1994 and from eared seals in 2008. Although few pathological findings have been associated with infection in true seals, reproductive pathology including abortions, and the isolation of the zoonotic strain type 27 have been documented in eared seals. In this study, a Brucella enzyme-linked immunosorbent assay (ELISA) and the Rose Bengal test (RBT) were initially compared for 206 serum samples and a discrepancy between the tests was found. Following removal of lipids from the serum samples, ELISA results were unaltered while the agreement between the tests was improved, indicating that serum lipids affected the initial RBT outcome. For the remaining screening, we used ELISA to investigate the presence of Brucella antibodies in sera of 231 eared and 1,412 true seals from Alaskan waters sampled between 1975 and 2011. In eared seals, Brucella antibodies were found in two Steller sea lions (Eumetopias jubatus) (2%) and none of the 107 Northern fur seals (Callorhinus ursinus). The low seroprevalence in eared seals indicate a low level of exposure or lack of susceptibility to infection. Alternatively, mortality due to the Brucella infection may remove seropositive animals from the population. Brucella antibodies were detected in all true seal species investigated; harbor seals (Phoca vitulina) (25%), spotted seals (Phoca largha) (19%), ribbon seals (Histriophoca fasciata) (16%), and ringed seals (Pusa hispida hispida) (14%). There was a low seroprevalence among pups, a higher seroprevalence among juveniles, and a subsequent decreasing probability of seropositivity with age in harbor seals. Similar patterns were present for the other true seal species; however, solid conclusions could not be made due to sample size. This pattern is in accordance with previous reports on B. pinnipedialis infections in true seals and may suggest environmental exposure to B. pinnipedialis at the juvenile stage, with a following clearance of infection. Furthermore, analyses by region showed minor differences in the probability of being seropositive for harbor seals from different regions regardless of the local seal population trend, signifying that the Brucella infection may not cause significant mortality in these populations. In conclusion, the Brucella infection pattern is very different for eared and true seals. PMID- 29445730 TI - Pilot study of a smartphone application designed to socially motivate cardiovascular disease patients to improve medication adherence. AB - Background: Social support received by patients from family and community has been identified as a key factor for success in improving medication adherence in those patients. This pilot study aimed to investigate the usability and feasibility of PillPal, a smartphone application that uses video-chatting as a social motivation medium to encourage medication adherence in cardiovascular disease (CVD) patients. We additionally gathered feedback on the Physician Calendar, an accompanying web platform that allows clinicians to view patient adherence data generated from the app. Methods: Thirty patients were recruited from the Johns Hopkins Hospital (JHH) Lipid Clinic (n=14) and Inpatient Cardiology Service (n=16) to pilot test the app. Data were obtained through in person interviews in which patients tested out the app and answered standardized questions regarding the app's feasibility as a means to enhance social support, as well as its usability measured in terms of ease of use and patient comfort level with the video-chat technology. Cardiologists (n=10) from JHH were interviewed to gain feedback on the Physician Calendar. Results: We recorded 43.4% participants who stated that PillPal would increase their motivation to take their medications; 96.7% stated the app was easy to use; and 70% stated they were comfortable with video-chatting while taking their medications. Patient factors such as current adherence level, disease severity, and personality were more predictive of positive app reviews than the perceived level of social support. Clinicians generally approved of the Physician Calendar, as they would be able to quickly screen for non-adherence and begin conversations with patients to address the root cause of their non-adherence. Conclusions: Based on pilot testing and interviews, using a smartphone app for video-chatting as a social support medium to improve patient medication adherence is feasible and has potential to increase medication adherence depending on certain patient characteristics. The Physician Calendar was deemed a useful tool by clinicians to quickly identify and understand reasons for medication non-adherence. PMID- 29445731 TI - Expecting great expectations when expecting. AB - Pregnancy is a time when a woman experiences a number of unexpected biological, psychological and social changes. Traditionally, woman sought guidance and help from their mothers and/or social circles to learn how to tackle these changes. With the advent of the mobile revolution, women are now turning to mobile applications to do the same. In this article, we review a pregnancy tracking mobile application called Ovia, in the light of the comments made by mothers using it from around the world. We learn that women like Ovia because it allows them to track, monitor and explore their pregnancy journey by receiving personalized guidance.

AB - Mitochondria change their morphology dynamically by continual fusion and fission processes to fulfill their function. However, little is known about the effect of cardiac arrest on mitochondrial dynamics. This study aimed to investigate time dependent change of the mitochondrial dynamics after brain ischemic injury in rats of cardiac arrest. After resuscitation, obvious neuronal injury, reduced adenosine triphosphate (ATP) levels, excessive reactive oxygen species (ROS) generation, decreased mitochondrial membrane potential (MMP), and increased release of mitochondrial cytochrome c were observed at 12 h and 24 h after cardiac arrest. Moreover, we found that elongation of mitochondria was observed at 4 h after cardiac arrest, whereas fragmented mitochondria were significantly increased, along with concomitant increase in the fission proteins Drp1 and Fis1 and a reduction in the fusion proteins Mfn1 and Mfn2 at 12 h and 24 h after cardiac arrest. Taken together, these findings suggest that imbalance in mitochondrial dynamics probably contributes to brain injury after cardiac arrest.

AB - The facultative intracellular pathogen Listeria monocytogenes causes a severe food-borne infection in humans and animals. L. monocytogenes invasion factor InlB interacts with the tyrosine kinase c-Met via the N-terminal internalin domain. Previously, distinct variants of the InlB internalin domain (idInlB) have been described in L. monocytogenes field isolates. Three variants were used to restore full-length InlB expression in the L. monocytogenes strain EGDeDeltainlB. Obtained isogenic L. monocytogenes strains were tested in the invasion assay and intravenous, intraperitoneal, and intragastric models of infection in mice. All idInlBs were functional, restored InlB activity as an invasion factor, and improved invasion of the parental strain EGDeDeltainlB into human kidney HEK23 cells. Meanwhile, distinct idInlBs provided different mortality rates and bacterial loads in internal organs. When recombinant strains were compared, the variant designated idInlB14 decreased severity of disease caused by intravenous and intraperitoneal bacterial administration, whereas this variant improved intestine colonization and stimulated intragastric infection. Obtained results demonstrated that naturally occurring idInlBs differed in their impact on severity of L. monocytogenes infection in mice in dependence on the infection route.

PMID- 29445736 TI - Tuberculosis Treatment Outcomes and Factors Associated with Each of Them in a Cohort Followed Up between 2010 and 2014. AB - Tuberculosis treatment has undergone recent changes in Brazil. Objective. To assess whether favorable outcomes on tuberculosis therapy improved in recent years. Methods. Retrospective observational study, based on primary data of tuberculosis patients, followed at INI-FIOCRUZ, from January 2012 to December 2014. Results. The outcomes observed were as follows: cure (80%), default (14%), treatment failure (5%), and death (1%). HIV infection without antiretroviral therapy [OR 0.34 (0.15-0.79)], tuberculosis diagnosis based on sputum smear [OR 0.22 (0.07-0.74)], drug use [OR 0.22 (0.11-0.46)], and/or treatment interruption due to adverse reactions [OR 0.23 (0.08-0.67)] decreased the chance of cure. Predictors of default, that is, use of noninjecting drugs [OR 3.00 (95% CL 1.31 6.88)], treatment interruption due to adverse reactions [OR 6.30 (1.81-21.95)], low schooling [OR 2.59 (2.15-5.82)], higher age [OR 0.44 (0.23-0.82)], and female gender [OR 0.28 (0.11-0.71)], reduced the chance of treatment default. Tuberculosis diagnosis based on sputum smear [OR 7.77 (1.94-31.09)] and/or arterial hypertension [OR 4.07 (1.25-13.18)] was associated with treatment failure. Conclusion. Mortality and default were low considering the prevalence of HIV infection; however cure was not significantly increased. PMID- 29445734 TI - Failure of the PTEN/aPKC/Lgl Axis Primes Formation of Adult Brain Tumours in Drosophila. AB - Different regions in the mammalian adult brain contain immature precursors, reinforcing the concept that brain cancers, such as glioblastoma multiforme (GBM), may originate from cells endowed with stem-like properties. Alterations of the tumour suppressor gene PTEN are very common in primary GBMs. Very recently, PTEN loss was shown to undermine a specific molecular axis, whose failure is associated with the maintenance of the GBM stem cells in mammals. This axis is composed of PTEN, aPKC, and the polarity determinant Lethal giant larvae (Lgl): PTEN loss promotes aPKC activation through the PI3K pathway, which in turn leads to Lgl inhibition, ultimately preventing stem cell differentiation. To find the neural precursors responding to perturbations of this molecular axis, we targeted different neurogenic regions of the Drosophila brain. Here we show that PTEN mutation impacts aPKC and Lgl protein levels also in Drosophila. Moreover, we demonstrate that PI3K activation is not sufficient to trigger tumourigenesis, while aPKC promotes hyperplastic growth of the neuroepithelium and a noticeable expansion of the type II neuroblasts. Finally, we show that these neuroblasts form invasive tumours that persist and keep growing in the adult, leading the affected animals to untimely death, thus displaying frankly malignant behaviours. PMID- 29445737 TI - Effects of TLR3 and TLR9 Signaling Pathway on Brain Protection in Rats Undergoing Sevoflurane Pretreatment during Cardiopulmonary Bypass. AB - Objective: To investigate the effects of TLR3 and TLR9 signaling pathway on brain injury during CPB in rats pretreated with sevoflurane and its possible molecular mechanism. Methods: SD rats were randomly assigned to sham group, CPB group, and Sev group. Brain tissue was obtained at before CPB (T0), at CPB for 30 minutes (T1), 1 hour after CPB (T3), and 3 hours after CPB (T5). ELISA was used to measure S100-beta and IL-6. Western blot was utilized to determine TLR3 and TLR9 expression. TUNEL was applied to detect neuronal apoptosis. Results: Compared with CPB group, at T1, at termination after 1 hour of CPB (T2), T3, 2 hours after CPB (T4) and T5, S100-beta and IL-6 decreased in Sev group. Compared with CPB group, IFN-beta were increased in Sev group, except T0. Compared with CPB group, TLR3 expression increased, and TLR9 and NF-kappaB decreased in Sev group. The apoptotic neurons were less in Sev group than in CPB group (P < 0.05). Conclusion: Sevoflurane intervention can activate TLR3 and TLR9 signaling pathway, upregulate TLR3 expression and downstream TRIF expression, decrease TLR9 expression, and downregulate downstream NF-kappaB expression in CPB rat models, thereby mitigating brain injury induced by inflammatory response during CPB. PMID- 29445738 TI - Expression of Cancer Stem Cell Marker CD44 and Its Polymorphisms in Patients with Chronic Gastritis, Precancerous Gastric Lesion, and Gastric Cancer: A Cross Sectional Multicenter Study in Thailand. AB - Here we investigated CD44 protein expression and its polymorphisms in patients with chronic gastritis, precancerous gastric lesions, and gastric cancer; and we evaluated our result with the risk of CD44 protein expression and clinicopathological characteristics. Our results obtained by analyzing 162 gastric cancer patients, 125 chronic gastritis, and 165 precancerous gastric lesions from three study centers in Thailand showed that CD44 expression was significantly higher in patients with precancerous gastric lesions and gastric cancer while patients with chronic gastritis were negative for CD44 staining (p = 0.036). We further observed the significant association of variant genotype; gastric cancer patients carrying AG or GG of CD44 rs187116 had more increased risk of CD44 expression than wild-type (WT) carriers (AG: odds ratio (OR) = 5.67; 95% CI = 1.57-7.23; p = 0.024 and GG: OR = 8.32; 95% CI = 2.94-11.42; p = 0.016), but no significant difference in the risk of CD44 expression due to polymorphism in patients with precancerous gastric lesions. Our results suggested that CD44 expression could be used as a marker for the prediction of gastric cancer development, particularly in patients with precancerous gastric lesions carrying AG or GG, who were selected to surveillance follow-up for gastric cancer prevention.

AB - The goal of the present study were (1) to investigate the pathological characteristics of gastrocnemius muscle (GM) and quantitatively assess GM tissue stiffness in rat models with spinal cord injury (SCI) and (2) to explore the correlation between pathological characteristics changes and Young's modulus value of GM. 24 Sprague Dawley male rats were allocated into normal control groups and SCI model subgroups, respectively. GM stiffness was assessed with shear wave sonoelastography technology. All GMs were further analyzed by pathological examinations. GM weights were decreased, the ratio of type I fibers was decreased, and the ratio of type II fibers was increased in the GM in the model group. MyHC-I was decreased, while MyHC-II was increased according to the electrophoretic analysis in model subgroups. The elastic modulus value of GM was increased in the model group. A significant negative correlation was found between Young's modulus value of GM and the ratio of type I fibers of GM in model subgroup. Our studies showed that the stiffness of GM is correlated with pathological characteristics during the initial stages of SCI in rats. We also identified shear wave sonoelastography technology as a useful tool to assess GM stiffness in SCI rat models. PMID- 29445741 TI - PSBinder: A Web Service for Predicting Polystyrene Surface-Binding Peptides. AB - Polystyrene surface-binding peptides (PSBPs) are useful as affinity tags to build a highly effective ELISA system. However, they are also a quite common type of target-unrelated peptides (TUPs) in the panning of phage-displayed random peptide library. As TUP, PSBP will mislead the analysis of panning results if not identified. Therefore, it is necessary to find a way to quickly and easily foretell if a peptide is likely to be a PSBP or not. In this paper, we describe PSBinder, a predictor based on SVM. To our knowledge, it is the first web server for predicting PSBP. The SVM model was built with the feature of optimized dipeptide composition and 87.02% (MCC = 0.74; AUC = 0.91) of peptides were correctly classified by fivefold cross-validation. PSBinder can be used to exclude highly possible PSBP from biopanning results or to find novel candidates for polystyrene affinity tags. Either way, it is valuable for biotechnology community.

AB - Infections caused by Candida albicans, often refractory and with high morbidity and mortality, cause a heavy burden on the public health while the current antifungal drugs are limited and are associated with toxicity and resistance. Many plant-derived molecules including compounds isolated from traditional Chinese medicine (TCM) are reported to have antifungal activity through different targets such as cell membrane, cell wall, mitochondria, and virulence factors. Here, we review the recent progress in the anti-Candida compounds from TCM, as well as their antifungal mechanisms. Considering the diverse targets and structures, compounds from TCM might be a potential library for antifungal drug development. PMID- 29445742 TI - Relationship between Undescended Testis Position and Prevalence of Testicular Appendices, Epididymal Anomalies, and Patency of Processus Vaginalis. AB - Objectives: To assess the incidence of testicular appendices (Tas), epididymal anomalies (EAs), and processus vaginalis (PV) patency in patients with undescended testis (UT) according to testicular position and to compare them with human fetuses. Methods: We studied 85 patients (108 testes) with cryptorchidism and compared the features with those of 15 fetuses (30 testes) with scrotal testes. We analyzed the relationships among the testis and epididymis, patency of PV, and the presence of TAs. We used the Chi-square test for statistical analysis (p < 0.05). Results: In 108 UT, 72 (66.66%) had PV patent, 67 (62.03%) had TAs, and 39 (36.12%) had EAs. Of the 108 UT, 14 were abdominal (12.96%; 14 had PV patency, 9 TAs, and 7 EAs); 81 were inguinal (75%; 52 had PV patency, 45 TAs, and 31 EAs), and 13 were suprascrotal (12.03%; 6 had PV patency, 13 TAs, and 1 EAs). The patency of PV was more frequently associated with EAs (p = 0.00364). The EAs had a higher prevalence in UT compared with fetuses (p = 0.0005). Conclusions: Undescended testis has a higher risk of anatomical anomalies and the testes situated in abdomen and inguinal canal have a higher risk of presenting patency of PV and EAs.

AB - The relationships between IVIM and DCE-MRI parameters in AS are not clear. We explore the correlation between intravoxel incoherent motion (IVIM) diffusion weighted imaging (DWI) and dynamic contrast-enhanced (DCE) parameters obtained on MR images in patients with ankylosing spondylitis (AS). Forty-four patients with AS were prospectively examined using a 1.5-T MR system. IVIM DWI was performed with 11 b values (range, 0-800 s/mm2) for all patients. The correlation coefficients between IVIM and DCE-MRI parameters were analyzed using Spearman's method. Our results showed that intra- and interobserver reproducibility were excellent to relatively good (ICC = 0.804-0.981; narrow width of 95% limits of agreement). Moderate positive correlations were observed between pure molecular diffusion (Ds) and maximum enhancement (ME) and relative enhancement (RE) (r = 0.700, P < 0.001; r = 0.607, P < 0.001, resp.). Perfusion-related diffusion (Df) showed negative moderate correlation with ME (r = -0.608, P < 0.001). However, no correlation was observed between perfusion fraction (f) and any parameters of ME, RE, TTP, and BE (r = -0.093-0.213; P > 0.165). In conclusion, the IVIM parameters, especially f, might play a critical role in detecting the progression of AS, because it can provide more perfusion information compared with DCE-MRI; besides the IVIM MRI is a noninvasive method. PMID- 29445744 TI - Simvastatin Ameliorates PAK4 Inhibitor-Induced Gut and Lung Injury. AB - P21 activated kinase 4 (PAK4), a key regulator of cytoskeletal rearrangement and endothelial microparticles (EMPs), is released after lipopolysaccharide (LPS) stimulation. In addition, it participates in LPS-induced lung injury. In this study, forty-eight Sprague Dawley (SD) rats were divided into two groups, including PAK4 inhibitor (P) and PAK4 inhibitor + simvastatin (P + S) treatment groups. All rats were given PAK4 inhibitor (15 mg/kg/d) orally. Immediately after PAK4 inhibitor administration, simvastatin was injected intraperitoneally to P + S group animals at 20 mg/kg/day. Then, treatment effects on the intestinal mucosal barrier and lung injury caused by PAK4 inhibitor and simvastatin were assessed. The results showed that gut Zonula Occludens- (ZO-) 1, PAK4, mitogen activated protein kinase 4 (MPAK4), and CD11c protein levels were reduced, while plasma endotoxin levels were increased after administration of PAK4 inhibitor. Furthermore, compared with normal rats, wet-to-dry (W/D) values of lung tissues and circulating EMP levels were increased in the treatment group, while PAK4 and CD11c protein amounts were reduced. Therefore, in this lung injury process induced by PAK4 inhibitor, the protective effects of simvastatin were reflected by intestinal mucosal barrier protection, inflammatory response regulation via CD11c+ cells, and cytoskeleton stabilization. In summary, PAK4 is a key regulator in the pathophysiological process of acute lung injury (ALI) and can be a useful target for ALI treatment.

AB - Background: Scientific evidence in the field of implant dentistry of the past 20 years established that titanium rough surfaces have shown improved osseointegration rates. In a majority of dental implants, the surface microroughness was obtained by grit blasting and/or acid etching. The aim of the study was to evaluate in vivo two different highly hydrophilic surfaces at different experimental times. Methods: Calcium-modified (CA) and SLActive surfaces were evaluated and a total of 18 implants for each type of surface were positioned into the rabbit articular femoral knee-joint in a split model experiment, and they were evaluated histologically and histomorphometrically at 15, 30, and 60 days of healing. Results: Bone-implant contact (BIC) at the two implant surfaces was significantly different in favor of the CA surface at 15 days (p = 0.027), while SLActive displayed not significantly higher values at 30 (p = 0.51) and 60 days (p = 0.061). Conclusion: Both implant surfaces show an intimate interaction with newly formed bone.

AB - This study aimed at evaluating the ability of SL-44 to control Rhizoctonia solani and promote pepper (Capsicum annuum) growth. Strain SL-44 was isolated from plant rhizosphere and the pot experiment results indicated that the dry and fresh weights of pepper in SL-44 and Rhizoctonia solani (S-R) treatment were 45.5% and 54.2% higher than those in Rhizoctonia solani (R) treatment and 18.2% and 31.8% higher than those in CK (control, noninoculation) treatment. The plant height in S-R treatment increased by 14.2% and 9.0% compared with those in the R and CK treatments, respectively. In vitro antagonism assay showed that SL-44 exhibited strong antifungal activity against the mycelial growth of Rhizoctonia solani, with an inhibition rate of 42.3%. The amount of phosphorus dissolved by SL-44 reached 60.58 mg.L-1 in broth and 7.5 MUg.mL-1 IAA were secreted by SL-44. Strain SL-44 inhibited the growth of R. solani and improved biomass of pepper plants. Mass exchange and information transmission between the pepper plants and SL-44 mutually promoted their development. Bacillus subtilis SL-44 has a great potential as biocontrol agent against Rhizoctonia solani on pepper plants. PMID- 29445748 TI - Oxidation Resistance of the Sulfur Amino Acids: Methionine and Cysteine. AB - Sulfur amino acids are a kind of amino acids which contain sulfhydryl, and they play a crucial role in protein structure, metabolism, immunity, and oxidation. Our review demonstrates the oxidation resistance effect of methionine and cysteine, two of the most representative sulfur amino acids, and their metabolites. Methionine and cysteine are extremely sensitive to almost all forms of reactive oxygen species, which makes them antioxidative. Moreover, methionine and cysteine are precursors of S-adenosylmethionine, hydrogen sulfide, taurine, and glutathione. These products are reported to alleviate oxidant stress induced by various oxidants and protect the tissue from the damage. However, the deficiency and excess of methionine and cysteine in diet affect the normal growth of animals; thereby a new study about defining adequate levels of methionine and cysteine intake is important. PMID- 29445749 TI - Impact of Chestnut and Quebracho Tannins on Rumen Microbiota of Bovines. AB - The use of phytogenic dietary additives is being evaluated as a means to improve animal productivity. The effect of tannins seems to be the influence not only directly on the digestive process through binding of dietary proteins but also indirectly over their effects on gastrointestinal microbiota. High-throughput sequencing of 16S rRNA gene was used to analyze the impact of dietary supplementation with a blend of chestnut and quebracho tannins on the rumen microbiota of Holstein steers. Bacterial richness was lower in tannins treated animals, while the overall population structure of rumen microbiota was not significantly disturbed by tannins. The ratio of the phyla Firmicutes and Bacteroidetes, a parameter associated with energy harvesting function, was increased in tannins supplemented animals, essentially due to the selective growth of Ruminococcaceae over members of genus Prevotella. Fibrolytic, amylolytic, and ureolytic bacterial communities in the rumen were altered by tannins, while methanogenic archaea were reduced. Furthermore, ruminal pH was significantly higher in animals supplemented with tannins than in the control group, while urease activity exhibited the opposite pattern. Further work is necessary to assess the relation between tannins impact on rumen microbiota and alteration of rumen fermentation parameters associated with bovine performance. PMID- 29445750 TI - The Association between Monocyte Surface CD163 and Insulin Resistance in Patients with Type 2 Diabetes. AB - Aim: To investigate the association between monocyte CD163 and insulin resistance in patients with type 2 diabetes. Methods: One hundred sixty-six patients with type 2 diabetes without inflammatory or chronic kidney disease were recruited. The monocyte CD163 levels were measured by flow cytometry and soluble CD163 (sCD163) by ELISA. Insulin resistance was evaluated by the index of the homeostasis model assessment (HOMA-R). Results: The median sCD163 and monocyte CD163 expression levels were 582.9 (472.4-720.0) ng/ml and 6061 (4486-7876) mean fluorescent intensity (MFI), respectively. In a simple regression analysis, monocyte CD163 was inversely correlated with log [HOMA-R] (r = -0.257, p = 0.010), and sCD163 was positively correlated with log [HOMA-R] (r = 0.198, p = 0.042). In multiple regression analyses, monocyte CD163 was an independent contributor to log [HOMA-R] (beta = -0.220, p = 0.020) even after adjustment of various clinical factors for HOMA-R (R2 = 0.281, p = 0.001), whereas sCD163 was not. Conclusions: Monocyte surface CD163 expression levels were more significantly associated with insulin resistance than sCD163 in patients with type 2 diabetes, suggesting a novel pathophysiological role of CD163. PMID- 29445751 TI - Circulating Nesfatin-1 Levels and Type 2 Diabetes: A Systematic Review and Meta Analysis. AB - The role of nesfatin-1 in glucose homeostasis has been investigated previously. However, although numerous studies have examined the relationships between circulating nesfatin-1 levels and type 2 diabetes, the conclusions are contradictory. We aimed to probe the relationship between circulating nesfatin-1 levels and type 2 diabetes by meta-analysis. Seven studies including 328 type 2 diabetes patients and 294 control subjects were included. Although there was no obvious difference in circulating nesfatin-1 levels between patients with type 2 diabetes and the control group (MD = -0.04; 95% CI = -0.32 to -0.23), subgroup analysis showed higher nesfatin-1 levels in newly diagnosed type 2 diabetes patients (MD = 0.59; 95% CI = 0.45 to 0.74) and significantly lower nesfatin-1 levels in type 2 diabetes patients receiving antidiabetic treatment (MD = -0.26; 95% CI = -0.33 to -0.20). In conclusion, the analysis supports a relationship between circulating nesfatin-1 levels and type 2 diabetes, where newly diagnosed type 2 diabetes was associated with an elevated Nesfatin-1 level, and type 2 diabetes patients receiving antidiabetic treatment showed lower circulating nesfatin-1 levels. PMID- 29445752 TI - Improvement in Neuropathy Specific Quality of Life in Patients with Diabetes after Vitamin D Supplementation. AB - Objective: To assess the effect of vitamin D supplementation on neuropathy specific quality of life (NeuroQoL) in patients with painful diabetic neuropathy. Methods: This prospective, open label study was conducted between June 2012 and April 2013. Patients with symptomatic diabetic neuropathy were given a single dose of 600,000 IU intramuscular vitamin D, and NeuroQol was assessed at baseline and at five follow-up visits every 4 weeks. Results: Of 143 participants, 41.3% were vitamin D deficient (vitamin D < 20 ng/ml). Treatment with vitamin D resulted in a significant increase in 25(OH)D (P < 0.0001) and a significant improvement in the NeuroQoL subscale score for emotional distress (P = 0.04), with no significant change in the other NeuroQoL domains of painful symptoms and paresthesia, loss of temperature and touch sensation, unsteadiness, limitation in daily activities, and interpersonal problems. There was a significant reduction in patient perception about foot problems on QoL of "quite a lot" (P < 0.05) and "very much" (P < 0.0001) with a significant reduction in the baseline response of having a "poor" QoL from 5.2% to 0.7% (P < 0.0001) and an increase in the response of an "excellent QoL" from 1.5% to 7.4% (P < 0.0001). Conclusion: Vitamin D is effective in improving quality of life in patients with painful diabetic neuropathy. PMID- 29445753 TI - Treatments for Severe Cutaneous Adverse Reactions. AB - Severe cutaneous adverse reaction (SCAR) is life-threatening. It consists of Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN), drug reaction with eosinophilia and systemic symptoms (DRESS), acute generalized exanthematous pustulosis (AGEP), and generalized bullous fixed drug eruptions (GBFDE). In the past years, emerging studies have provided better understandings regarding the pathogenesis of these diseases. These diseases have unique presentations and distinct pathomechanisms. Therefore, theoretically, the options of treatments might be different among various SCARs. However, due to the rarity of these diseases, sufficient evidence is still lacking to support the best choice of treatment for patients with SCAR. Herein, we will provide a concise review with an emphasis on the characteristics and treatments of each SCAR. It may serve as a guidance based on the current best of knowledge and may shed light on the directions for further investigations.

AB - Objective: This study aimed to explore the immunoregulatory effect of flavonoids of blueberry (Vaccinium corymbosum L.) leaves (FBL). Methods: The flavonoids of blueberry leaves were prepared with 70% ethanol and were identified by ultraperformance liquid chromatography/quadrupole-time-of-flight mass spectrometry (UPLC/Q-Tof-MS). The immunoregulatory effect and possible regulatory mechanisms of FBL were investigated in lipopolysaccharide- (LPS-) induced RAW 264.7 cells. Results: According to the results of UPLC/Q-Tof-MS, nine flavonoids of blueberry leaves were identified. FBL showed a significant reduction in the production of TNF-alpha in LPS-stimulated RAW 264.7 cells. FBL significantly decreased the expression of NF-kappaB p65 and P-NF-kappaB p65 in LPS-induced RAW 264.7 cells in a dose-dependent manner. Conclusion: Our study showed the immunoregulatory effect of FBL through the suppression of TNF-alpha via the NF kappaB signal pathway.

PMID- 29445754 TI - Fundamentals and Methods for T- and B-Cell Epitope Prediction. AB - Adaptive immunity is mediated by T- and B-cells, which are immune cells capable of developing pathogen-specific memory that confers immunological protection. Memory and effector functions of B- and T-cells are predicated on the recognition through specialized receptors of specific targets (antigens) in pathogens. More specifically, B- and T-cells recognize portions within their cognate antigens known as epitopes. There is great interest in identifying epitopes in antigens for a number of practical reasons, including understanding disease etiology, immune monitoring, developing diagnosis assays, and designing epitope-based vaccines. Epitope identification is costly and time-consuming as it requires experimental screening of large arrays of potential epitope candidates. Fortunately, researchers have developed in silico prediction methods that dramatically reduce the burden associated with epitope mapping by decreasing the list of potential epitope candidates for experimental testing. Here, we analyze aspects of antigen recognition by T- and B-cells that are relevant for epitope prediction. Subsequently, we provide a systematic and inclusive review of the most relevant B- and T-cell epitope prediction methods and tools, paying particular attention to their foundations. PMID- 29445756 TI - Modulation of Tumor-Associated Macrophages (TAM) Phenotype by Platelet-Activating Factor (PAF) Receptor. AB - Platelet-activating factor (PAF) plays an important role in the pathogenesis of several types of tumors. The biological effects of PAF are mediated by the PAF receptor (PAFR), which can be expressed by tumor cells and host cells that infiltrate the tumor microenvironment. In the present study, we investigated the role of PAFR expressed by leukocytes that infiltrate two types of tumors, one that expresses PAFR (TC-1 carcinoma) and another that does not express the receptor (B16F10 melanoma) implanted in mice that express the receptor or not (PAFR KO). It was found that both tumors grew significantly less in PAFR KO than in wild-type (WT) mice. Analysis of the leukocyte infiltration shown in PAFR KO increased the frequency of neutrophils (Gr1+) and of CD8+ lymphocytes in B16F10 tumors and of CD4+ lymphocytes in TC-1 tumors. PAFR KO also had a higher frequency of M1-like (CD11c+) and lower M2-like (CD206+) macrophages infiltrated in both tumors. This was confirmed in macrophages isolated from the tumors that showed higher iNOS, lower arginase activity, and lower IL10 expression in PAFR KO tumors than WT mice. These data suggest that in the tumor microenvironment, endogenous PAF-like activity molecules bind PAFR in macrophages which acquire an M2-like profile and this promotes tumor growth.

AB - Cerebral aneurysms (CAs) have become a health burden not only because their rupture is life threatening, but for a series of devastating complications left in survivors. It is well accepted that sustained chronic inflammation plays a crucial role in the pathology of cerebral aneurysms. In particular, macrophages have been identified as critical effector cells orchestrating inflammation in CAs. In recent years, dysregulated M1/M2 polarization has been proposed to participate in the progression of CAs. Although the pathological mechanisms of M1/M2 imbalance in CAs remain largely unknown, recent advances have been made in the understanding of the molecular basis and other immune cells involving in this sophisticated network. We provide a concise overview of the mechanisms associated with macrophage plasticity and the emerging molecular targets.

AB - Several genome-wide association studies have identified a polymorphism located 35 kb upstream of the coding region of HLA-C gene (rs9264942; termed -35 C/T) as a host factor significantly associated with the control of HIV-1 viremia in untreated patients. The potential association of this host genetic polymorphism with the viral reservoirs has never been investigated, nor the association with the viral control in response to the treatment. In this study, we assess the influence of the polymorphism -35 C/T on the outcome of virus burden in 183 antiretroviral-naive HIV-1-infected individuals who initiated antiviral treatment (study STIR-2102), analyzing HIV-1 RNA viremia and HIV-1 DNA reservoirs. The rs9264942 genotyping was investigated retrospectively, and plasma levels of HIV-1 RNA and peripheral blood mononuclear cell- (PBMC-) associated HIV-1 DNA were compared between carriers and noncarriers of the protective allele -35 C before antiretroviral therapy (ART), one month after ART and at the end of the study (36 months). HIV-1 RNA and HIV-1 DNA levels were both variables significantly different between carriers and noncarriers of the allele -35 C before ART. HIV-1 DNA levels remained also significantly different one month posttherapy. However, this protective effect of the -35 C allele was not maintained after long-term ART. PMID- 29445760 TI - Corneal functional optical zone under monocular and binocular assessment. AB - Background: In this retrospective randomized case series, we compared bilateral symmetry between OD and OS eyes, intercorneal differences and Functional Optical Zone (FOZ) of the corneal aberrations. Methods: Sixty-seven normal subjects (with no ocular pathology) who never had any ocular surgery were bilaterally evaluated at Augenzentrum Recklinghausen (Germany). In all cases, standard examinations and corneal wavefront topography (OPTIKON Scout) were performed. The OD/OS bilateral symmetry was evaluated for corneal wavefront aberrations, and FOZ-values were evaluated from the Root-Mean-Square (RMS) of High-Order Wavefront-Aberration (HOWAb). Moreover, correlations of FOZ, spherical equivalent (SE), astigmatism power, and cardinal and oblique astigmatism for binocular vs. monocular, and binocular vs. intercorneal differences were analyzed. Results: Mean FOZ was 6.56 +/- 1.13 mm monocularly, 6.97 +/- 1.34 mm binocularly, and 7.64 +/- 1.30 mm intercorneal difference, with all strongly positively correlated, showing that the diameter of glare-free vision is larger in binocular than monocular conditions. Mean SE was 0.78 +/- 1.30 D, and the mean astigmatism power (magnitude) was 0.46 +/- 0.52 D binocularly. The corresponding monocular values for these metrics were 0.78 +/- 1.30 D and 0.53 +/- 0.53 D respectively. SE, astigmatism magnitude, cardinal astigmatism component, and FOZ showed a strong correlation and even symmetry; and oblique astigmatism component showed odd symmetry indicating Enantiomorphism between the left and right eye. Conclusions: These results confirm OD-vs.-OS bilateral symmetry (which influences binocular summation) of HOWAb, FOZ, defocus, astigmatism power, and cardinal and oblique astigmatism. Binocular Functional Optical Zone calculated from corneal wavefront aberrations can be used to optimize refractive surgery design. PMID- 29445761 TI - Oxidative Stress Assays (arsenite and tBHP) in Caenorhabditis elegans. AB - Cells and organisms face constant exposure to reactive oxygen species (ROS), either from the environment or as a by-product from internal metabolic processes. To prevent cellular damage from ROS, cells have evolved detoxification mechanisms. The activation of these detoxification mechanisms and their downstream responses represent an overlapping defense response that can be tailored to different sources of ROS to adequately adapt and protect cells. In this protocol, we describe how to measure the sensitivity to oxidative stress from two different sources, arsenite and tBHP, using the nematode C. elegans. PMID- 29445762 TI - Distribution and Seasonal Activity of Phlebotominae Sand Flies in Yazd and Its Outskirts, Center of Iran. AB - Background: Phlebotominae sand flies are the main vectors of leishmaniasis and some other diseases. Materials and Methods: Using sticky traps, sand flies were collected fortnightly from outdoors and indoors areas of selected sites. Results: A total of 2032 specimens (498 in the city and 1534 in the outskirts of Yazd) belonging to 11 species were collected. The activity of sand flies started in early-April and ended in mid-November. There were two peaks of activity in the end of April and mid-September. Phlebotomus sergenti and P. papatasi were the most abundant species in the city and outskirts of Yazd city, respectively. Other species were P. salehi, P. ansarii, P. kazerouni, P. caucasicus, P. andrejevi, P. alexandri, P. mongolensis, Sergentomyia sintoni, and S. palestinensis. Conclusion: In comparison to some other parts of Iran, the extended period between two peaks suggests that the larvae to adult development of sand fly were delayed by the higher temperature of the summer months in Yazd province.

AB - Molecular identification and characterization of fear controlling circuitries is a promising path towards developing targeted treatments of fear-related disorders. Three-color in situ hybridization analysis was used to determine whether somatostatin (SOM, Sst), neurotensin (NTS, Nts), corticotropin-releasing factor (CRF, Crf), tachykinin 2 (TAC2, Tac2), protein kinase c-delta (PKC-delta, Prkcd), and dopamine receptor 2 (DRD2, Drd2) mRNA colocalize in male mouse amygdala neurons. Expression and colocalization was examined across capsular (CeC), lateral (CeL), and medial (CeM) compartments of the central amygdala. The greatest expression of Prkcd and Drd2 were found in CeC and CeL. Crf was expressed primarily in CeL, while Sst-, Nts-, and Tac2-expressing neurons were distributed between CeL and CeM. High levels of colocalization were identified between Sst, Nts, Crf, and Tac2 within the CeL, while little colocalization was detected between any mRNAs within the CeM. These findings provide a more detailed understanding of the molecular mechanisms that regulate the development and maintenance of fear and anxiety behaviors. PMID- 29445765 TI - In Vivo Observation of Structural Changes in Neocortical Catecholaminergic Projections in Response to Drugs of Abuse. AB - Catecholaminergic (dopamine and norepinephrine) projections to the cortex play an important role in cognitive functions and dysfunctions including learning, addiction, and mental disorders. While dynamics of glutamatergic synapses have been well studied in such contexts, little is known regarding catecholaminergic projections, owing to lack of robust methods. Here we report a system to monitor catecholaminergic projections in vivo over the timeframes that such events occur. Green fluorescent protein (GFP) expression driven by tyrosine hydroxylase promoter in a transgenic mouse line enabled us to perform two-photon imaging of cortical catecholaminergic projections through a cranial window. Repetitive imaging of the same axons over 24 h revealed the highly dynamic nature of catecholaminergic boutons. Surprisingly, administration of single high dose methamphetamine (MAP) induced a transient increase in bouton volumes. This new method opens avenues for longitudinal in vivo evaluation of structural changes at single release sites of catecholamines in association with physiology and pathology of cortical functions. PMID- 29445766 TI - Ventral and Dorsal Pathways Relate Differently to Visual Awareness of Body Postures under Continuous Flash Suppression. AB - Visual perception includes ventral and dorsal stream processes. However, it is still unclear whether the former is predominantly related to conscious and the latter to nonconscious visual perception as argued in the literature. In this study upright and inverted body postures were rendered either visible or invisible under continuous flash suppression (CFS), while brain activity of human participants was measured with functional MRI (fMRI). Activity in the ventral body-sensitive areas was higher during visible conditions. In comparison, activity in the posterior part of the bilateral intraparietal sulcus (IPS) showed a significant interaction of stimulus orientation and visibility. Our results provide evidence that dorsal stream areas are less associated with visual awareness. PMID- 29445767 TI - Serotonin Differentially Regulates L5 Pyramidal Cell Classes of the Medial Prefrontal Cortex in Rats and Mice. AB - The prefrontal cortex receives a dense serotonergic innervation that plays an important role in its regulation. However, how serotonin regulates different pyramidal and interneuron cell classes in this area is incompletely understood. Previous work in rats has shown that serotonin differentially regulates two classes of pyramidal cells in layer 5. It excites one class by activating 5-HT2A receptors, whereas it more subtly modulates the integrative properties of the other by co-activating 5-HT1A and 5-HT2A receptors. Here we have used electrophysiological recordings, combined with retrograde labeling and morphological reconstruction, to show that the first cell class corresponds to long range corticofugal neurons and the second corresponds to intratelencephalic neurons. These results suggest that, in rats, serotonin facilitates subcortical output while more subtly modulating cortico-cortical and cortico-striatal output. Interestingly, these results obtained in rats differ from those previously reported for mouse prefrontal cortex. Therefore we reinvestigated the effects of serotonin in mice and confirmed that serotonin predominantly activates inhibitory 5-HT1A receptors on long-range corticofugal cells. Thus serotonin exerts opposite effects on these cells in rats and mice. Finally, we determined whether cortical serotonin responsiveness in mice is regulated during development. Serotonin elicited predominantly depolarizing inward current responses during the early postnatal period, whereas inhibitory 5-HT1A receptor-mediated responses did not become evident until the end of the second postnatal week. These results reveal commonalities as well as unexpected differences in the serotonergic regulation of long-range corticofugal and intratelencephalic neurons of layer 5 in rat and mouse. PMID- 29445768 TI - HsTRPA of the Red Imported Fire Ant, Solenopsis invicta, Functions as a Nocisensor and Uncovers the Evolutionary Plasticity of HsTRPA Channels. AB - Solenopsis invicta, the red imported fire ant, represents one of the most devastating invasive species. To understand their sensory physiology, we identified and characterized their Hymenoptera-specific (Hs) TRPA channel, SiHsTRPA. Consistent with the sensory functions of SiHsTRPA, it is activated by heat, an electrophile, and an insect repellent. Nevertheless, SiHsTRPA does not respond to most of the honey bee ortholog (AmHsTRPA)-activating compounds. The jewel wasp ortholog (NvHsTRPA) is activated by these compounds even though it outgroups both AmHsTRPA and SiHsTRPA. Characterization of AmHsTRPA/SiHsTRPA chimeric channels revealed that the amino acids in the N terminus, as well as ankyrin repeat 2 (AR2) of AmHsTRPA, are essential for the response to camphor. Furthermore, amino acids in ARs 3 and 5-7 were specifically required for the response to diallyl disulfide. Thus, amino acid substitutions in the corresponding domains of SiHsTRPA during evolution would be responsible for the loss of chemical sensitivity. SiHsTRPA-activating compounds repel red imported fire ants, suggesting that SiHsTRPA functions as a sensor for noxious compounds. SiHsTRPA represents an example of the species-specific modulation of orthologous TRPA channel properties by amino acid substitutions in multiple domains, and SiHsTRPA-activating compounds could be used to develop a method for controlling red imported fire ants. PMID- 29445769 TI - Prefrontal theta-Burst Stimulation Disrupts the Organizing Influence of Active Short-Term Retrieval on Episodic Memory. AB - Dorsolateral prefrontal cortex (DLPFC) is thought to organize items in working memory and this organizational role may also influence long-term memory. To causally test this hypothesized role of DLPFC in long-term memory formation, we used theta-burst noninvasive stimulation (TBS) to modulate DLPFC involvement in a memory task that assessed the influence of active short-term retrieval on later memory. Human subjects viewed three objects on a grid and then either actively retrieved or passively restudied one object's location after a brief delay. Long term memory for the other objects was assessed after a delay to evaluate the beneficial role of active short-term retrieval on subsequent memory for the entire set of object locations. We found that DLPFC TBS had no significant effects on short-term memory. In contrast, DLPFC TBS impaired long-term memory selectively in the active-retrieval condition but not in the passive-restudy condition. These findings are consistent with the hypothesized contribution of DLPFC to the organizational processes operative during active short-term retrieval that influence long-term memory, although other regions that were not stimulated could provide similar contributions. Notably, active-retrieval and passive-restudy conditions were intermixed, and therefore nonspecific influences of stimulation were well controlled. These results suggest that DLPFC is causally involved in organizing event information during active retrieval to support coherent long-term memory formation. PMID- 29445770 TI - Subthalamic Neural Activity Patterns Anticipate Economic Risk Decisions in Gambling. AB - Economic decision-making is disrupted in individuals with gambling disorder, an addictive behavior observed in Parkinson's disease (PD) patients receiving dopaminergic therapy. The subthalamic nucleus (STN) is involved in the inhibition of impulsive behaviors; however, its role in impulse control disorders and addiction is still unclear. Here, we recorded STN local field potentials (LFPs) in PD patients with and without gambling disorder during an economic decision making task. Reaction times analysis showed that for all patients, the decision whether to risk preceded task onset. We compared then for both groups the STN LFP preceding high- and low-risk economic decisions. We found that risk avoidance in gamblers correlated with larger STN LFP low-frequency (<12-Hz) fluctuations preceding task onset. In particular, the amplitude of low-frequency LFP fluctuations carried significant information about future decisions. Decisions of patients not affected by gambling disorder were instead not correlated with pretask STN LFP. Our results suggest that STN activity preceding task onset affects risk decisions by preemptively inhibiting attraction to high but unlikely rewards in favor of a long-term payoff. PMID- 29445771 TI - Biomimetic Rotated Lamellar Plywood Motifs by Additive Manufacturing of Metal Alloy Scaffolds for Bone Tissue Engineering. AB - Additive manufacturing presents opportunities to treat bone defects using biomimetic tissue scaffolds. Past investigations have explored modulating scaffold mechanical properties through varying materials and geometric motifs. Herein, we applied the rotated plywood structure of bone tissue to a 3D printed scaffold with the goal of improving mechanical performance compared to an orthogonal mesh design commonly used in tissue scaffold applications. The scaffolds were subjected to uniaxial compression followed by scanning electron microscopy and microcomputer tomography. The uniaxial compression test was characterized through elastic modulus (mean 1.32 GPa biomimetic, 0.196 GPa orthogonal, p < 0.001), ultimate compressive strength (mean 16.546 MPa biomimetic, 6.309 MPa orthogonal design, p < 0.001), and ultimate compressive strain values (4.867% biomimetic, 9.000% orthogonal, p < 0.005). Correlation of microfracture imaging to bulk scaffold mode of failure suggest that utilizing the biomimetic plywood design not only improved mechanical performance, but also reduced asymmetrtic buckling, plastic deformation, and fracture propagation similar to bone tissue. PMID- 29445772 TI - A Review of Evidence Based Treatments for Transgender Youth Diagnosed with Social Anxiety Disorder. AB - In addition to the high prevalence of gender dysphoria among transgender youth, this population is at greater risk of suffering from additional mental health disorders, including social anxiety disorder, compared to their cisgender peers. Cognitive behavioral therapy (CBT) has been established as an effective form of treatment for social anxiety disorder. It is recommended that therapists modify and adapt CBT when working with minority groups such as transgender youth to ensure that the treatment is efficacious and culturally sensitive. However, literature assessing the efficacy of CBT for transgender youth with mental health issues is scant. As a result, there is no empirical literature on effective treatment for transgender youth who meet criteria for social anxiety disorder alone or youth who meet criteria for social anxiety disorder and gender dysphoria. This literature review aims to identify current research related to prevalence of mental health disorders in transgender youth, the current literature on adaptations of cognitive behavioral techniques, and the need for treatment research on adaptation of CBT for transgender individuals, specifically those with social anxiety disorder and gender dysphoria. PMID- 29445773 TI - Leveraging tuberculosis case relative locations to enhance case detection and linkage to care in Swaziland. AB - Background: In Swaziland, as in many high HIV/TB burden settings, there is not information available regarding the household location of TB cases for identifying areas of increased TB incidence, limiting the development of targeted interventions. Data from "Butimba", a TB REACH active case finding project, was re-analyzed to provide insight into the location of TB cases surrounding Mbabane, Swaziland. Objective: The project aimed to identify geographical areas with high TB burdens to inform active case finding efforts. Methods: Butimba implemented household contact tracing; obtaining landmark based, informal directions, to index case homes, defined here as relative locations. The relative locations were matched to census enumeration areas (known location reference areas) using the Microsoft Excel Fuzzy Lookup function. Of 403 relative locations, an enumeration area reference was detected in 388 (96%). TB cases in each census enumeration area and the active case finders in each Tinkhundla, a local governmental region, were mapped using the geographic information system, QGIS 2.16. Results: Urban Tinkhundla predictably accounted for most cases; however, after adjusting for population, the highest density of cases was found in rural Tinkhundla. There was no correlation between the number of active case finders currently assigned to the 7 Tinkhundla surrounding Mbabane and the total number of TB cases (Spearman rho = -0.57, p = 0.17) or the population adjusted TB cases (Spearman rho = 0.14, p = 0.75) per Tinkhundla. Discussion: Reducing TB incidence in high-burden settings demands novel analytic approaches to study TB case locations. We demonstrated the feasibility of linking relative locations to more precise geographical areas, enabling data-driven guidance for National Tuberculosis Programs' resource allocation. In collaboration with the Swazi National Tuberculosis Control Program, this analysis highlighted opportunities to better align the active case finding national strategy with the TB disease burden. PMID- 29445774 TI - An evaluation of immunization services, using the reaching every district criteria, in two districts of Gujarat, India. AB - Background: Immunizations are considered the most successful and cost-effective public health interventions employed today. While immunization coverage in India has improved dramatically in the last decade, areas of very low coverage persist. The University of Michigan School of Public Health and the Indian Institute of Public Health Gandhinagar collaborated to document strengths and weaknesses of immunization service delivery in two districts in India. Methods: This report describes a qualitative assessment of clinic level immunization service delivery in ten primary health centers (PHCs) located in two districts of Gujarat, India. Assessment criteria were derived from the Reaching Every District (RED) strategy that is intended to provide a framework for delivering childhood immunizations. Staff from the PHCs were interviewed in April 2013. Results: Interviews revealed several barriers to immunization service delivery including: 1) Vaccine and supply stockouts; 2) Hard to reach communities; 3) Unreliable Internet access; 4) Cold chain equipment malfunctions; 5) Inconsistently maintained and utilized immunization records and registries. Conclusions: Immunization service delivery is a complex process that can encounter barriers at many stages. A RED-based evaluation of the vaccine delivery system in Gujarat, India identified several points where the system was performing sub-optimally and possible solutions to successfully address these challenges. PMID- 29445775 TI - Torsion bottle, a very simple, reliable, and cheap tool for a basic scoliosis screening. AB - Background: One of the reasons that make scoliosis a disease that scares so much the parents is its specific characteristic of being difficult to detect on its onset.The aim of this paper is to check the possible usefulness of a simple tool (the torsion bottle) that has been developed with the aim to offer an instrument for home use by parents but also for screening purposes in the low-income countries. Methods: Study design: retrospective analysis to evaluate intra operator reliability of the tools and inter-operator repeatability using the torsion bottle.For the first and the second part of the study, 35 subjects were measured.The goal of the first experiment was to evaluate the reliability of the torsion bottle to identify all individuals who experienced a thoracic or lumbar prominence equal or greater than 7 degrees .The secondary aim was to verify the reliability of blinded inter-operator assessments, performed with the torsion bottle by two physiotherapists on the same patients. Results: The reliability of the assessments of the torsion bottle has been performed with the Kappa statistic to evaluate the measurement agreement.The results have shown that the intra operator reliability of the tool is very high between the measurements collected with the scoliometer(r) and those collected with the torsion bottle (kappa = 0.9278; standard error = 0.7094).The data of the second part of the study show that the inter-operator reliability is good (kappa = 0.7988; standard error 0.1368). Conclusion: The collected data showed that the torsion bottle revealed itself as an efficient tool to execute a basic screening to identify the presence of a prominence in a significant group of adolescents. PMID- 29445776 TI - Retinal nerve fiber layer sector-specific compromise in relapsing and remitting multiple sclerosis. AB - Objective: To evaluate quadrant and sector retinal nerve fiber layer (RNFL) thickness and total macular volume (TMV) in relapsing-remitting multiple sclerosis (RR-MS) patients. Methods: Optical coherence tomography measures of RNFL and TMV were studied in 321 eyes without prior optic neuritis (ON) (MS unaffected), 151 eyes with prior ON (MS affected), and 148 healthy control eyes. Results: Mean RNFL thickness was significantly lower in the MS affected and MS unaffected groups relative to the control group (p < 0.0001). RNFL thicknesses in the superior, inferior, and temporal quadrants were significantly reduced in MS unaffected (113 +/- 15 MUm, 119 +/- 17 MUm, 63 +/- 13 MUm) (p < 0.001) and MS affected groups (99 +/- 19 MUm, 103 +/- 21 MUm, 51 +/- 13 MUm) (p < 0.0001) compared with that in controls (120 +/- 14 MUm, 128 +/- 15 MUm, 69 +/- 8 MUm, respectively). TMV was significantly reduced in both the MS affected and MS unaffected groups compared with that in the controls (p < 0.0001). Conclusion: Quadrant, sector, and PMB RNFL thicknesses are significant individual measures in RR-MS for both affected and unaffected eyes and may prove valuable in future investigations including biomarker and outcomes research.

There is a weak intramolecular pi-pi contact between the two phenyl rings, with a centroid-to-centroid distance of 4.004 (2) A. The dihedral angle between the rings is 9.96 (13) degrees .

PMID- 29445778 TI - NADPH Oxidase-4 Driven Cardiac Macrophage Polarization Protects Against Myocardial Infarction-Induced Remodeling. AB - The reactive oxygen species-generating enzyme NADPH oxidase 4 (Nox4) is up regulated in the heart after myocardial infarction (MI). Mice with cardiomyocyte targeted Nox4 overexpression (TG) displayed increased macrophages in the heart at baseline, with skewing toward an M2 phenotype compared with wild-type controls (WT). After MI, TG mice had a higher proportion of M2 macrophages along with higher survival, decreased cardiac remodeling, and better contractile function than wild-type mice. The post-MI increase in cardiac matrix metalloproteinase-2 activity was substantially blunted in TG mice. These results indicate that cardiomyocyte Nox4 modulates macrophage polarization toward an M2 phenotype, resulting in improved post-MI survival and remodeling, likely through the attenuation of cardiac matrix metalloproteinase-2 activity. PMID- 29445779 TI - Wireless Sensor-Dependent Ecological Momentary Assessment for Pediatric Asthma mHealth Applications. AB - Pediatric asthma is a prevalent chronic disease condition that can benefit from wireless health systems through constant symptom management. In this paper, we propose a smart watch based wireless health system that incorporates wireless sensing and ecological momentary assessment (EMA) to determine an individual's asthma symptoms. Since asthma is a multifaceted disease, this approach provides individualized symptom assessments through various physiological and environmental wireless sensor based EMA triggers specific to common asthma exacerbations. Furthermore, the approach described here improves compliance to use of the system through insightful EMA scheduling related to sensor detected environmental and physiological changes, as well as the patient's own schedule. After testing under several real world conditions, it was found that the system is sensitive to both physiological and environmental conditions that would cause asthma symptoms. Furthermore, the EMA questionnaires that were triggered based on these changes were specific to the asthma trigger itself, allowing for invaluable context behind the data to be collected. PMID- 29445780 TI - Actinide-based MOFs: a middle ground in solution and solid-state structural motifs. AB - In this review, we highlight how recent advances in the field of actinide structural chemistry of metal-organic frameworks (MOFs) could be utilized towards investigations relative to efficient nuclear waste administration, driven by the interest towards development of novel actinide-containing architectures as well as concerns regarding environmental pollution and nuclear waste storage. We attempt to perform a comprehensive analysis of more than 100 crystal structures of the existing An (U,Th)-based MOFs to establish a correlation between structural density and wt% of actinide and bridge structural motifs common for natural minerals with ones typically observed in the solution chemistry of actinides. In addition to structural considerations, we showcase the benefits of MOF modularity and porosity towards the stepwise building of hierarchical material complexity and the capture of nuclear fission products, such as technetium and iodine. We expect that these facets not only contribute to the fundamental science of actinide chemistry, but also could foreshadow pathways for more efficient nuclear waste management. PMID- 29445781 TI - Membrane bound COMT isoform is an interfacial enzyme: general mechanism and new drug design paradigm. AB - The enzyme catechol-O-methyltransferase (COMT) has water soluble (S-COMT) and membrane associated (MB-COMT), bitopic, isoforms. Of these MB-COMT is a drug target in relation to the treatment of Parkinson's disease. Using a combination of computational and experimental protocols, we have determined the substrate selection mechanism specific to MB-COMT. We show: (1) substrates with preferred affinity for MB-COMT over S-COMT orient in the membrane in a fashion conducive to catalysis from the membrane surface and (2) binding of COMT to its cofactor ADOMET induces conformational change that drives the catalytic surface of the protein to the membrane surface, where the substrates and Mg2+ ions, required for catalysis, are found. Bioinformatics analysis reveals evidence of this mechanism in other proteins, including several existing drug targets. The development of new COMT inhibitors with preferential affinity for MB-COMT over S-COMT is now possible and insight of broader relevance, into the function of bitopic enzymes, is provided. PMID- 29445783 TI - The construction of fluorescent heteropore covalent organic frameworks and their applications in spectroscopic and visual detection of trinitrophenol with high selectivity and sensitivity. AB - Two fluorescent covalent organic frameworks (COFs) which bear two kinds of pores with different sizes and shapes have been synthesized.

PMID- 29445785 TI - A signal-on, colorimetric determination of deoxyribonuclease I activity utilizing the photoinduced synthesis of gold nanoparticles. AB - A simple, colorimetric method is developed for the determination of deoxyribonuclease I (DNase I) activity based on the novel finding that DNase I can promote the photoinduced synthesis of gold nanoparticles (AuNPs). In the absence of DNase I, a phosphorothioate (PS) DNA probe remains intact and captures Au(iii) through a strong Au-thiol interaction, which prevents the photoinduced synthesis of AuNPs, leaving the sample in a colorless state. On the other hand, in the presence of DNase I, the PS DNA probe is cleaved into small fragments that are removed via a simple purification process. The resulting solution, after the incubation with HAuCl4 and threonine (Thr), forms AuNPs by UV light irradiation with the aid of Thr which acts as a catalyst for the Au(iii) reduction process. As a result, a red-colored suspension is produced. By monitoring the color changes of the samples with the naked eye, the DNase I activity was conveniently determined. In addition, the clinical utility of this simple, yet highly efficient colorimetric strategy was verified by reliably quantifying the DNase I activities in a bovine urine sample. Importantly, the working principle designed for the determination of DNase I activity was successfully expanded for the detection of target nucleic acids, ensuring the universal applicability of the developed assay system. PMID- 29445786 TI - Amplified polarization properties of electrospun nanofibers containing fluorescent dyes and helical polymer. AB - Nanofibers with the cationic fluorescent molecules, 1-pyrenemethylamine hydrochloride (PyrMA) and alpha,beta,gamma,delta-tetrakis(1-methylpyridinium-4 yl)porphyrin p-toluenesulfonate (TMPyP), in the presence of complementary anionic chiral polysaccharide, hyaluronic acid (HA) and transparent polymer, polyethylene oxide (PEO) were successfully prepared using an electrospinning technique. The results showed that the fluorescence spectra of electrospun nanofibers (ENFs) of PEO-HA-PyrMA exhibit a higher amount of pyrene excimer emission when the [PyrMA]/[HA] ratio was increased from 0.5 to 1, while the concentration of TMPyP had no remarkable effect on the fluorescence of the PEO-HA-TMPyP ENFs. From circular dichroism (CD) characterization, the ENFs of both dyes exhibit stronger intensities in the apparent CD spectra upon increasing the dye ratio. Moreover, they also showed higher CD intensities when compared with those of solutions and thin films prepared using other methods. The apparent CD in this work was proved to mainly originate from linear dichroism (LD) and linear birefringence (LB) obtained by macroscopic alignment along the electrospinning process. These results suggest the advantages of molecular orientation via electrospinning, together with chirality induction by incorporation of a chiral HA polymer. The enhancement of these polarization properties provides great possibilities for improving fluorescent-chiral nanofibers for further optoelectronic applications. PMID- 29445787 TI - Nanoparticles based on glycyrrhetinic acid modified porphyrin for photodynamic therapy of cancer. AB - Self-assembled small molecules, as a novel form of drug presentation, have splendid capabilities for water stability and cell endocytosis. Photodynamic therapy (PDT) is regarded as a promising cancer treatment because it is less invasive and has fewer side effects. In this work, an amphiphilic glycyrrhetinic acid-porphyrin conjugate (TPP-GA) was designed and synthesized, and this could self-assemble into nanoparticles (TPP-GA NPs) in water. The morphology of the TPP GA NPs was observed using transmission electron microscopy (TEM) and their stability in water was revealed by dynamic light scattering (DLS). The PDT effect of the TPP-GA NPs was confirmed by means of in vitro experiment, after photostability verification. It could be conceived that the application of TPP-GA NPs for PDT is a feasible choice and this work shows progress in the self assembly of amphiphilic small organic molecules.

AB - A facile synthetic route is presented to fabricate highly ordered three dimensional hierarchical CoO/MnCo2O4.5 nanorod arrays on carbon cloth (CC) as a high performance anode material for lithium ion batteries (LIBs). Inheriting the merits from the CC substrate and the special hierarchical architecture, as well as the interfacial and synergistic effects between CoO nanorods and MnCo2O4.5 nanosheets, the as-prepared product exhibits outstanding electrochemical performance in terms of high reversible capacity, cycling stability, and rate capability. Electrochemical characterization depicts that the hierarchical CoO/MnCo2O4.5 nanorod electrode can retain a high reversible capacity of about 1183 mA h g-1 at 200 mA-1 for the second cycle and a high rate capacity of 657 mA h g-1 at 1000 mA-1. After 120 cycles, a reversible capacity of 1030 mA h g-1 at 200 mA-1 can be maintained without obvious decay. These results demonstrate that the hierarchical CoO/MnCo2O4.5 nanorod array on CC is a promising candidate as an anode material for LIBs with superior properties.

AB - We report a green fabrication of conductive paper based on in situ polymerization of polymerizable deep eutectic solvents (PDESs) through a screen printing process.

AB - It is highly desirable to develop efficient and durable oxygen evolution reaction (OER) electrocatalysts. Herein, we report the in situ development of an Fe (tetracyanoquinodimethane)2 nanowire array on Fe foil (Fe(TCNQ)2/Fe) via a solution immersion method. As a non-noble-metal OER electrocatalyst, such Fe(TCNQ)2/Fe needs an overpotential of only 340 mV to drive a geometrical catalytic current density of 10 mA cm-2 in 1.0 M KOH. Notably, it also shows strong long-term electrochemical durability capable of maintaining its catalytic activity for at least 110 h. PMID- 29445792 TI - Understanding receptor-mediated endocytosis of elastic nanoparticles through coarse grained molecular dynamic simulation. AB - For nanoparticle (NP)-based drug delivery platforms, the elasticity of the NPs has a significant influence on their blood circulation time and cellular uptake efficiency. However, due to the complexity of the endocytosis process and the inconsistency in the definition of elasticity for NPs in experiments, the understanding about the receptor-mediated endocytosis process of elastic NPs is still limited. In this work, we developed a coarse-grained molecular dynamics (CGMD) model for elastic NPs. The energy change of the elastic NPs can be precisely controlled by the bond, area, volume and bending potentials of this CGMD model. To represent liposomes with different elasticities, we systematically varied the bending rigidity of elastic NPs in CGMD simulations. Additionally, we changed the radius of the elastic NPs to explore the potential size effect. Through virtual nano-indentation tests, we found that the effective stiffness of elastic NPs was determined by their bending rigidity and size. Afterwards, we investigated the receptor-mediated endocytosis process of elastic NPs with different sizes and bending rigidities. We found that the membrane wrapping of soft NPs was faster than that of the stiff ones at the early stage, due to the NP deformation induced large contact area between the NPs and the membrane. However, because of the large energy penalties induced by the NP deformation, the membrane wrapping speed of soft NPs slows down during the late stage. Eventually, the soft NPs are wrapped less efficiently than the stiff ones during the membrane wrapping process. Through systematic CGMD simulations, we found a scaling law between the cellular uptake efficiency and the phenomenal bending rigidity of elastic NPs, which agrees reasonably well with experimental observations. Furthermore, we observed that the membrane wrapping efficiencies of soft and stiff NPs with large sizes were close to each other, due to the stronger ligand-receptor binding force and smaller difference in the stiffness of elastic NPs. Our computational model provides an effective tool to investigate the receptor-mediated endocytosis of elastic NPs with well controlled mechanical properties. This study can also be applied to guide the design of NP-based drug carriers with high efficacy, by utilizing their elastic properties.

AB - C-S bond activation of thiophenols and mercaptans is of great importance but has rarely been reported. In this paper we report the C-S bond cleavage of the thiolato ligand of [2,6-(tBu2PO)2C6H3]NiSCH2Ph (1) mediated by BH3.THF. The treatment of 1 with an excess amount of BH3.THF in THF at room temperature afforded the borohydride complex [2,6-(tBu2PO)2C6H3]Ni(eta2-BH4) (2) as the only product. The reaction of 1 with 2 equiv. of BH3.THF in THF at room temperature for 48 h produced the hydride complex [2,6-(tBu2PO)2C6H3]NiH (3) and the mercapto complex [2,6-(tBu2PO)2C6H3]NiSH (5). As a new complex, 5 was also independently synthesized by a salt metathesis reaction of the corresponding chloride complex with NaSH and fully characterized by multinuclear NMR, FTIR, HRMS, X-ray crystallography and elemental analysis. A possible mechanism for the formation of 5 was proposed. It was supposed that 5 formed through BH3 mediated C-S bond cleavage of the thiolato ligand of 1. The result would initiate further studies on the transition metal catalyzed borane mediated C-S bond activation of mercaptans. PMID- 29445794 TI - High-pressure dissociation of selenium and tellurium. AB - Pressure-induced molecular dissociation provides significant insights into chemical bonding, governing the physical properties of molecular solids. Here the typical molecular solids, selenium and tellurium, have been explored experimentally to unearth the process of pressure-induced molecular dissociation. Before molecular dissociation, both commensurately and incommensurately modulated structures have been observed in these two elements. Upon compression, the successive commensurate-incommensurate phase transitions are proved by the soft amplitude (AMP) mode. The fitted critical pressure suggests that the molecular dissociation of Te is inferred to occur at 26.1 GPa in agreement with our XRD and Raman data. The current precise structural studies before pressure-induced molecular dissociation demonstrated in the elements selenium and tellurium will help in clarifying the mechanisms of molecular dissociation in related molecular solids. PMID- 29445795 TI - Zwitterionic peptide-capped gold nanoparticles for colorimetric detection of Ni2+ . AB - Zwitterionic nanoparticles are typically utilized as nanoprobes and delivery vehicles in nanomedicine and therapeutics due to their resistance to interferences. Their high stability also shows great potential to be applied in sensing applications. Here, we report a selective, sensitive and rapid colorimetric sensing of nickel ions (Ni2+) using zwitterionic polypeptide, EKEKEKPPPPC (EK)3, capped gold nanoparticles (AuNP-(EK)3). By taking advantage of the alternate carboxylic (-COOH)/amine (-NH2) groups, the zwitterionic peptide can function dually by being able to sense metal ions and maintain colloidal stability. Ni2+ can trigger the aggregation of the AuNP-(EK)3 nanoprobe, which results in a red-to-purple color change of the AuNP-(EK)3 solution. Our 40 nm AuNP-(EK)3 nanoprobe can detect Ni2+ as low as 34 nM within 15 min with a linear range of 60-160 nM, and is stable in soil, urine and water samples. We demonstrate that the aggregation mechanism of the nanoprobe is due to the interactions between the -NH2 group of glutamic acid at the N-terminus of the peptide and Ni2+, and the aggregation process is reversible. Furthermore, the slight modification of two amino acid sequences at the N-terminus allows the nanoprobe to retain its stability, even in a high ionic strength medium. We believe that by adjusting or extending the peptide sequences, new metal ion selective peptides could be created.

AB - A low-coordinate iron(ii) complex (CztBu(PztBu)2)Fe[N(SiMe3)2], 1 bearing an NNN pincer ligand was prepared and fully characterized. Intramolecular C-H activation on the 5-position of a pyrazole at elevated temperatures was observed. Complex 1 was found to be an efficient and chemoselective pre-catalyst for the hydrosilylation of organo carbonyl substrates. PMID- 29445797 TI - Spectroscopy as a tool to detect multinuclear Cu(ii)-triethanolamine complexes in aqueous solution. AB - Complexes of Cu(ii) with triethanolamine (TEA) are widely used in aqueous precursor solutions of Cu-based catalysts and metal oxides such as YBa2Cu3O7 delta superconductors. An outstanding question is whether such complexes are multinuclear in solution. Here, we use various spectroscopic techniques to unmistakably prove the existence of such multimers. Firstly, we introduce an original approach based on NMR spectroscopy and the Evans method that establishes the existence of multimers in aqueous solution at pH 4 and higher, and allows precise monitoring of the formation of these complexes with increasing pH. Secondly, we use extended X-ray absorption fine structure (EXAFS) spectroscopy to show that a Cu-Cu interaction exists at pH 9.5, which is not observed in acidic (pH 2) solutions. Finally, NMRD measurements reveal additional structural information regarding the multinuclear complexes. Knowledge concerning the nature of Cu(ii)-TEA complexes in solution is of great relevance in view of the design of speciation models to predict the stability of copper triethanolamine-based precursor solutions. PMID- 29445798 TI - Solvation-controlled lithium-ion complexes in a nonflammable solvent containing ethylene carbonate: structural and electrochemical aspects. AB - The structural and electrochemical properties of lithium-ion solvation complexes in a nonflammable organic solvent, tris(2,2,2-trifluoroethyl)phosphate (TFEP) containing ethylene carbonate (EC), were investigated using vibrational spectroscopic and electrochemical measurements. Based on quantitative Raman and infrared (IR) spectral analysis of the Li bis(trifluoromethanesulfonyl)amide (TFSA) salt in TFEP + EC electrolytes, we successfully evaluated the individual solvation numbers of EC (nEC), TFEP (nTFEP), and TFSA- (nTFSA) in the first solvation sphere of the Li-ion. We found that the nEC value linearly increased with increasing EC mole fraction (xEC), whereas the nTFEP and nTFSA values gradually decreased with increasing nEC. The ionic conductivity and viscosity (Walden plots) indicated that mainly Li+TFSA- ion pairs formed in neat TFEP (xEC = 0). This ion pair gradually dissociated into positively charged Li-ion complexes as xEC increased, which was consistent with the Raman/IR spectroscopy results. The redox reaction corresponding to an insertion/desertion of Li-ion into/from the graphite electrode occurred in the LiTFSA/TFEP + EC system at xEC >= 0.25. The same was not observed in the lower xEC cases. We discussed the relation between Li-ion solvation and electrode reaction behaviors at the molecular level and proposed that nEC plays a crucial role in the electrode reaction, particularly in terms of solid electrolyte interphase formation on the graphite electrode. PMID- 29445799 TI - DNA nanodevices monitored with fluorogenic looped-out 2-aminopurine. AB - We report several DNA nanodevices monitored with fluorogenic looped-out 2 aminopurine. It is found that looped-out 2-AP, an analogue of adenine, in split parallel G-quadruplexes, triplexes and duplexes always shows much higher fluorescence intensity than that in single- or double-stranded DNAs, due to the weaker quenching effects derived from the reduced base stacking environments. Taking advantage of these traits, we introduce a new strategy to monitor the behaviours of DNA nanodevices via the fluorescence signal output by utilizing changes in the base stacking environment of 2-AP. As proof-of-principle experiments, two nanoplatforms for detecting disease genes, as well as a triplex nanoswitch, are constructed and monitored by fluorogenic looped-out 2-AP, illustrating that fluorogenic looped-out 2-AP holds great promise for reading the behaviours of diverse DNA nanodevices. Compared with conventional fluorescence labelling, looped-out 2-AP as a reporter shows good photostability and can be quenched by base-pairing, thereby providing an efficient quencher-free methodology for monitoring DNA nanodevices. PMID- 29445800 TI - Acoustic separation in plastic microfluidics for rapid detection of bacteria in blood using engineered bacteriophage. AB - A more effective treatment of bacteremia requires a diagnostic platform that is both sensitive, accurate and rapid. Currently, clinical laboratory techniques require growth of bacteria prior to diagnosis, take days to complete, and leave empiric therapy and broad spectrum antibiotics as the only option at the onset of treatment. In order to bypass this growth requirement, we engineered a system that purifies bacteria from blood to improve performance in a bacteriophage-based luminescence assay. To perform the purification, we used acoustophoresis in plastic microfluidic chips, enabling future development into a low cost point-of care system. Acoustophoresis achieves differential separation on the basis of size differences between bacteria and blood cells. We show isolation of three known pathogen species, including members of both Gram-negative and positive bacteria from blood, and show isolation at clinically relevant concentrations. Using the device as a preparation step prior to the bacteriophage-based luminescence assay, we demonstrate a 33-fold improvement in limit of detection, compared with the unpurified sample, achieving a limit of detection of 6 bacteria. PMID- 29445801 TI - Liquid crystal self-assembly of upconversion nanorods enriched by depletion forces for mesostructured material preparation. AB - Monodisperse rod-like colloidal particles are known for spontaneously forming both nematic and smectic liquid crystal phases, but their self-assembly was typically exploited from the fundamental soft condensed matter physics perspective. Here we demonstrate that depletion interactions, driven by non adsorbing polymers like dextran and surfactants, can be used to enrich the self organization of photon-upconversion nanorods into orientationally ordered nematic and smectic-like membrane colloidal superstructures. We study thermodynamic phase diagrams and demonstrate polarization-dependent photon upconversion exhibited by the ensuing composites, which arises from the superposition of unique properties of the solid nanostructures and the long-range ordering enabled by liquid crystalline self-organization. Finally, we discuss how our method of utilizing self-assembly due to the steric and electrostatic interactions, along with attractive depletion forces, can enable technological uses of lyotropic colloidal liquid crystals and mesostructured composite materials enabled by them, even when they are formed by anisotropic nanoparticles with relatively small aspect ratios. PMID- 29445802 TI - Pulsatile plasma filtration and cell-free DNA amplification using a water-head driven point-of-care testing chip. AB - We demonstrate a microfiltration chip that separates blood plasma by using water head-driven pulsatile pressures rather than any external equipment and use it for on-chip amplification of nucleic acids. The chip generates pulsatile pressures to significantly reduce filter clogging without hemolysis, and consists of an oscillator, a plasma-extraction pump, and filter units. The oscillator autonomously converts constant water-head pressure to pulsatile pressure, and the pump uses the pulsatile pressure to extract plasma through the filter. Because the pulsatile pressure can periodically clear blood cells from the filter surface, filter clogging can be effectively reduced. In this way, we achieve plasma extraction with 100% purity and 90% plasma recovery at 15% hematocrit. During a 10 min period, the volume of plasma extracted was 43 MUL out of a 243 MUL extraction volume at 15% hematocrit. We also studied the influence of the pore size and diameter of the filter, blood loading volume, oscillation period, and hematocrit level on the filtration performance. To demonstrate the utility of our chip for point-of-care testing (POCT) applications, we successfully implemented on-chip amplification of a nucleic acid (miDNA21) in plasma filtered from blood. We expect our chip to be useful not only for POCT applications but also for other bench-top analysis tools using blood plasma. PMID- 29445803 TI - Poly(vinylidene fluoride)/poly(3-methylthiophene) core-shell nanocomposites with improved structural and electronic properties of the conducting polymer component. AB - We report significant improvements in the structure and electronic properties of a poly(3-alkylthiophene) representative, namely poly(3-methylthiophene) (P3MT), when it is synthesized in the presence of submicron electroactive poly(vinylidene fluoride) (PVDF) particles. The applied template oxidative synthesis leads to the formation of the PVDF/P3MT composite consisting of core-shell particles. The shells are constituted with a monolayer of 20-40 nm nanoparticles of the doped P3MT (P3MT-Cl) precipitated at the surface of the spherical PVDF cores. This morphology differs strongly from the hierarchical one of the neat P3MT synthesized without PVDF particles. In the latter case, 20-60 nm P3MT nanoparticles form ~200 nm aggregates, which, in turn, are arranged in a few micrometer agglomerates. Furthermore, we demonstrate that compared to the neat polymer, doped P3MT in the shells of the composite is characterized with higher effective conjugation length, regioregularity of the molecular structure, improved intrachain packing order and lower bipolaron/polaron ratio. These features of the PVDF/P3MT composite strongly suggest applicability of this material in various electronic devices. As a proof of concept, we report on an improved sensing performance of the PVDF/P3MT-Cl composite compared with the neat P3MT-Cl in detection of several volatile organic compounds known as markers for some diseases and toxic substances. We have discovered that the maximal improvement in the sensor response magnitude corresponds to the case when the values of the analyte electronegativity and polythiophene work function are close. We associate this behavior with a higher surface dipole component of the work function of the PVDF/P3MT-Cl composite compared to that of the neat conducting polymer.

AB - 1,6-Bis(hydroxymethyl)diamantane spontaneously aligns inside double-walled carbon nanotubes. The encapsulated molecules form a one-dimensional network within the double-walled carbon nanotubes through hydrogen bonding that leads to a highly dense filling as compared to unfunctionalized diamantane. Improving the encapsulation yields of precursors via functionalization is crucial to prepare novel one-dimensional materials. PMID- 29445805 TI - Transition of surface phase of cobalt oxide during CO oxidation. AB - In situ/operando studies of a heterogeneous catalyst are particularly valuable for achieving a fundamental understanding of catalytic mechanisms at a molecular level by establishing a correlation between the observed catalytic performance and the corresponding surface chemistry during catalysis. Herein, CO oxidation on cobalt oxides was studied via ambient pressure X-ray photoelectron spectroscopy (AP-XPS). During CO oxidation on CoO in the temperature range of 140-180 degrees C, the active surface phase of CoO progressively transforms to Co3O4. Kinetic studies of CO oxidation on the surface phase CoO at 80-120 degrees C and on the formed Co3O4 at 160-220 degrees C show that CoO and Co3O4 exhibit different activation barriers: 49.3 kJ mol-1 for CoO and 36.9 kJ mol-1 for Co3O4. This study demonstrates the transition of the active surface phase of a transition metal oxide-based catalyst under catalytic conditions with no change in the bulk phase of the catalyst. PMID- 29445806 TI - Intercalation of metformin into montmorillonite. AB - Metformin hydrochloride is an extensively used antidiabetic drug that according to the results reported here is able to spontaneously intercalate layered silicates like the montmorillonite clay mineral following an ion-exchange mechanism. The adsorption isotherm from water solutions shows a great affinity of metformin towards the clay mineral, which can retain about thrice the exchange capacity of the clay. The adsorbed excess was easily removed by washing with water, leading to an intercalation compound that contains 93 meq of metformin per 100 g of montmorillonite, matching the CEC value of this clay. The intercalated metformin is arranged in the interlayer space as a monolayer of monoprotonated molecules, which remain strongly entrapped within the solid. These new hybrid materials were characterized by elemental chemical analysis, XRD, FTIR, TG-DTA, and NMR. We preliminary evaluated the use of the metformin-montmorillonite intercalation compound as a drug delivery system, determining the liberation kinetics of metformin at diverse pH values that mimic the gastrointestinal tract. Although the release rate was not totally slowed down, the system seems promising in view of further optimization for drug delivery applications.

AB - The condensation of anthracene-9-carbaldehyde with 2 (phenylthio/seleno)ethylamine results in Schiff bases [PhS(CH2)2C[double bond, length as m-dash]N-9-C14H9](L1) and [PhSe(CH2)2C[double bond, length as m-dash]N 9-C14H9] (L2). On their reaction with [(eta5-Cp*)IrCl(MU-Cl)]2 and CH3COONa at 50 degrees C followed by treatment with NH4PF6, iridacycles, [(eta5-Cp*)Ir(L H)][PF6] (1: L = L1; 2: L = L2), result. The same reaction in the absence of CH3COONa gives complexes [(eta5-Cp*)Ir(L)Cl][PF6] (3-4) in which L = L1(3)/L2(4) ligates in a bidentate mode. The ligands and complexes were authenticated with HR MS and NMR spectra [1H, 13C{1H} and 77Se{1H} (in the case of L2 and its complexes only)]. Single crystal structures of L2 and half sandwich complexes 1-4 were established with X-ray crystallography. Three coordination sites of Ir in each complex are covered with eta5-Cp* and on the remaining three, donor atoms present are: N, S/Se and C-/Cl-, resulting in a piano-stool structure. The moisture and air insensitive 1-4 act as efficient catalysts under mild conditions for base free N-alkylation of amines with benzyl alcohols and transfer hydrogenation (TH) of aldehydes/ketones. The optimum loading of 1-4 as a catalyst is 0.1-0.5 mol% for both the activations. The best reaction temperature is 80 degrees C for transfer hydrogenation and 100 degrees C for N-alkylation. The mercury poisoning test supports a homogeneous pathway for both the reactions catalyzed by 1-4. The two catalytic processes are most efficient with 3 followed by 4 > 1 > 2. The mechanism proposed on the basis of HR-MS of the reaction mixtures of the two catalytic processes taken after 1-2 h involves the formation of an alkoxy and hydrido species. The real catalytic species proposed in the case of iridacycles results due to the loss of the Cp* ring. PMID- 29445808 TI - Multi-spectrometer calibration transfer based on independent component analysis. AB - Calibration transfer is indispensable for practical applications of near infrared (NIR) spectroscopy due to the need for precise and consistent measurements across different spectrometers. In this work, a method for multi-spectrometer calibration transfer is described based on independent component analysis (ICA). A spectral matrix is first obtained by aligning the spectra measured on different spectrometers. Then, by using independent component analysis, the aligned spectral matrix is decomposed into the mixing matrix and the independent components of different spectrometers. These differing measurements between spectrometers can then be standardized by correcting the coefficients within the independent components. Two NIR datasets of corn and edible oil samples measured with three and four spectrometers, respectively, were used to test the reliability of this method. The results of both datasets reveal that spectra measurements across different spectrometers can be transferred simultaneously and that the partial least squares (PLS) models built with the measurements on one spectrometer can predict that the spectra can be transferred correctly on another. PMID- 29445809 TI - Lithium doping on 2D squaraine-bridged covalent organic polymers for enhancing adsorption properties: a theoretical study. AB - Lithium modification, especially quantitative and oriented doping, is an effective way to enhance the adsorption properties of covalent organic frameworks (e.g., CO2 and H2). Two-dimensional squaraine-bridged covalent organic polymers (SQ-COPs), with quantitative and oriented Li-doped open oxygen sites of the squaric-acid unit, are investigated for their CO2 capture properties by using first-principles calculation combined with grand canonical Monte Carlo (GCMC) simulation. It is found that owing to the strong affinity of Li atoms to the squaraine units of SQ-COPs, the gas adsorption capacity in SQ-COP-Li increased to 3 times more than those of the pristine SQ-COPs. In particular, since the Li-O bonds between squaraine units and Li atoms can enhance the electrostatic interaction between the framework and CO2, the adsorption amount of CO2 in SQ-COP Li reaches an extremely high capacity of 83.4 and 202.0 mmol g-1 at 298 K and 100 bar for 1-Li (SQ-COP-1-Li) and 3-Li (SQ-COP-3-Li), respectively. Such a high CO2 uptake means that 3-Li outperforms the best 3D COF (COF-05) materials so far reported, and is even twice that of MOF-177 and IRMOF-10. Even at 30 bar and 298 K, the CO2 uptake values of 49.2 mmol g-1 of 1-Li and 61.5 mmol g-1 of 3-Li are far higher than 29.7 mmol g-1 of Li-doped COF-102 and 42.0 mmol g-1 of Li-doped COF-105. Moreover, the selectivity of CO2/H2 and CO2/CH4 in 1-Li reaches 19 and 5.4 at 273 K, and 10.3 and 3.6 at 298 K, respectively. Therefore, such Li-doped SQ-COPs might be an environmentally friendly candidate for high CO2 capture. Furthermore, the possible synthesis pathways of SQ-COP-Li are investigated, and it is indicated that the use of lithium di-isopropylamide and lithium naphthalene as dopants is energetically favorable. The findings in this work are expected to provide new ideas for metal doping and extended applications of functionalized materials.

AB - BF3.Et2O promoted metal-free denitrogenative transannulation of N-sulfonyl-1,2,3 triazole was reported. Rather than transition metals, BF3.Et2O was employed for the first time to promote the formation of alpha-diazoimines from N-sulfonyl 1,2,3-triazoles in nitriles, leading to the synthesis of various imidazoles. The protocol tolerates a broad range of functional groups and could also be applied to the late-stage modification of bioactive molecules, demonstrating the potential of this protocol in organic synthesis. A plausible mechanism was proposed. PMID- 29445812 TI - 3D cellular structures and co-cultures formed through the contactless magnetic manipulation of cells on adherent surfaces. AB - A magnet array is employed to manipulate diamagnetic cells that are contained in paramagnetic medium to demonstrate for the first time the contactless bioprinting of three-dimensional (3D) cellular structures and co-cultures of breast cancer MCF-7 and endothelial HUVEC at prescribed locations on tissue culture treated well plates. Sequential seeding of different cell lines and the spatial displacement of the magnet array creates co-cultured cellular structures within a well without using physically intrusive well inserts. Both monotypic and co culture experiments produce morphologically rich 3D cell structures that are otherwise absent in regular monolayer cell cultures. The magnetic contactless bioprinting of cells provides further insight into cell behaviour, invasion strategies and transformations that are useful for potential applications in drug screening, 3D cell culture formation and tissue engineering. PMID- 29445813 TI - An insight into the origin of room-temperature ferromagnetism in SnO2 and Mn doped SnO2 quantum dots: an experimental and DFT approach. AB - SnO2 and Mn-doped SnO2 single-phase tetragonal crystal structure quantum dots (QDs) of uniform size with control over dopant composition and microstructure were synthesized using the high pressure microwave synthesis technique. On a broader vision, we systematically investigated the influence of dilute Mn ions in SnO2 under the strong quantum confinement regime through various experimental techniques and density functional theoretical (DFT) calculations to disclose the physical mechanism governing the observed ferromagnetism. DFT calculations revealed that the formation of the stable (001) surface was much more energetically favorable than that of the (100) surface, and the formation energy of the oxygen vacancies in the stable (001) surface was comparatively higher in the undoped SnO2 QDs. X-ray photoelectron spectroscopy (XPS) and first-principles modeling of doped QDs revealed that the lower doping concentration of Mn favored the formation of MnO-like (Mn2+) structures in defect-rich areas and the higher doping concentration of Mn led to the formation of multiple configurations of Mn (Mn2+ and Mn3+) in the stable surfaces of SnO2 QDs. Electronic absorption spectra indicated the characteristic spin allowed ligand field transitions of Mn2+ and Mn3+ and the red shift in the band gap. DFT calculations clearly indicated that only the substitutional dopant antiferromagnetic configurations were more energetically favorable. The gradual increase of magnetization at a low level of Mn-doping could be explained by the prevalence of antiferromagnetic manganese vacancy pairs. Higher concentrations of Mn led to the appearance of ferromagnetic interactions between manganese and oxygen vacancies. The increase in the concentration of metallic dopants caused not just an increase in the total magnetic moment of the system but also changed the magnetic interactions between the magnetic moments on the metal ions and oxygen. The present study provides new insight into the fundamental understanding of the origin of ferromagnetism in transition metal-doped QDs. PMID- 29445814 TI - Anisotropic flexible transparent films from remaining wood microstructures for screen protection and AgNW conductive substrate. AB - Flexible transparent conductive films or substrates prepared from plastics or cellulose are widely used in optoelectronic devices. However, all of these films or substrates are fabricated by complex and expensive methods, which consume much energy and time. In this work, we report for the first time a remarkably facile and effective approach for fabricating flexible transparent films directly from wood. The resulting films exhibit an array of exceptional optical and mechanical properties. The well-aligned cell structures in natural wood are maintained during delignification, leading to anisotropic films with high transparency (~90% transmittance). These anisotropic films with well-aligned cell structures show mechanical tensile strengths higher than those of the original wood, and can be used as screen protection films for cellphones. Furthermore, ultrathin, highly transparent, and outstandingly conductive films have been prepared from such films and silver nanowires (AgNWs) using the Meyer technique. A conductive film with an optimal area density (341 mg m-2) of AgNWs showed outstanding synergistic properties, with a transmittance of 80% and a sheet resistance of 11 Omega sq-1, equal to the conductivity of ITO. Of importance here is that the low-cost anisotropic transparent wood film shows promising potential for electronics applications in solar cells, flexible displays, and other products. PMID- 29445815 TI - Collisions of noble gas atoms with graphene and a graphene nanodome. AB - The collisions of noble gas atoms with graphene and a graphene nanodome were investigated by employing first principles molecular dynamics calculations. By analyzing the electron-related properties of the collision process, the atom dynamics and the deformation of the graphene/nanodome, our results show a difference between the elastic properties of the nanodome and graphene. Generally, the nanodome can more easily revert to its initial conformation. The final kinetic energy, Ef, of the atom that collides with the nanodome is larger than the Ef of the atom that collides with graphene. In addition, the relationship between the initial kinetic energy of the atom, Ek0, and its corresponding proportion of energy loss, chi, is linear (except for the Kr atom). Our research will probably contribute to the investigation of the 2D materials' mechanical properties and their surface morphology. Moreover, due to its novel mechanical properties, the graphene nanodome is an extraordinary nano architecture which can be employed to protect nano-devices from damage and injury.

Prolinol TMS ether catalyst in combination with benzoic acid was found to be the most effective for this reaction which proceeds through an equilibrium of lactols to provide a single diastereomer of enantiopure 2,4-disubstituted chromans. PMID- 29445820 TI - A drastic influence of the anion nature and concentration on high pressure intrusion-extrusion of electrolyte solutions in Silicalite-1. AB - High pressure intrusion-extrusion of concentrated solutions of sodium salts in a pure-silica MFI-type zeolite (Silicalite-1) was studied for potential applications in mechanical energy absorption and storage. It was discovered that the anion nature has a drastic influence on the behavior and the energetic performances of "Silicalite-1 - concentrated Na+X- solution" systems, where X = Cl-, Br-, I-, NO2-, NO3-, ClO4- and CrO42-. In the case of NaNO2, NaClO4, Na2CrO4, and NaI a combination of bumper and shock-absorber behaviors with a partial irreversible solution intrusion was observed, whereas a fully reversible spring behavior is demonstrated for the intrusion-extrusion of NaBr, NaCl and NaNO3 solutions. In comparison with water, the intrusion pressure increases for all the solutions except for NaClO4 one. The irreversibility of intrusion decreases with a dilution rate, and the behavior of the corresponding systems with diluted solutions becomes very close. The variation of the system behavior and intrusion pressure values can be related to a different affinity of the corresponding anions for the pores of Silicalite-1. The samples before and after intrusion-extrusion experiments were characterized using several structural and physicochemical methods (XRD, TGA, solid-state NMR, and N2 physisorption), but no significant structural difference was observed. PMID- 29445823 TI - Mixed-matrix materials using metal-organic polyhedra with enhanced compatibility for membrane gas separation. AB - Discrete metal-organic polyhedra (MOPs) containing copper(ii), palladium(ii), and iron(ii) nodes were synthesized as fillers for mixed-matrix materials (MMMs) with a polyvinylidine fluoride (PVDF) polymer phase and contrasted against an MMM containing a metal-organic framework, MOF-5. When a given MOP was soluble in the precursor solutions, the resulting MMMs were thin, flexible, and homogeneous based on microscopy and SEM imaging. Analogous MMM formation using either insoluble MOPs or the inherent insoluble MOF-5 showed a higher degree of phase separation and inhomogeneity. Even when a MOP was not fully soluble, a significant particle size decrease was observed in contrast to the MOF-5 materials wherein the crystallites remained largely intact. This is a consequence of solubilizing the MOP fillers into the polymer solvent. The crystallinity and thermal stabilities of the MMMs were compared to pure PVDF using powder X-ray diffraction, and differential scanning calorimetry, indicating that the incorporation of MOPs both decreased overall crystallinity as well as increased thermal stability. In addition, MMMs containing PdMOP and FeMOP showed improved gas permeabilities relative to pure PVDF for H2, N2, CH4, and CO2, with the 10 wt% FeMOP membrane more selective for CO2 over N2 and H2.

AB - Protic ionic liquid crystals (PILCs) obtained from natural sources are promising compounds due to their peculiar properties and sustainable appeal. However, obtaining PILCs with higher thermal and mechanical stabilities for product and process design is in demand and studies on such approaches using this new IL generation are still scarce. In this context, this work discloses an alternative way for tuning the physicochemical properties of ILCs by mixing PILs. New binary mixtures of PILs derived from fatty acids and 2-hydroxy ethylamines have been synthesized here and investigated through the characterization of the solid-solid [liquid crystal]-liquid thermodynamic equilibrium and their rheological and critical micellar concentration profiles. The mixtures presented a marked nonideal melting profile with the formation of solid solutions. This work revealed an improvement of the PILCs' properties based on a significant increase in the ILC temperature domain and the obtainment of more stable mesophases at high temperatures when compared to pure PILs. In addition, mixtures of PILs also showed significant changes in their non-Newtonian and viscosity profile up to 100 s-1, as well as mechanical stability over a wide temperature range. The enhancement of the physicochemical properties of PILs here disclosed by such an approach leads to more new possibilities of their industrial application at high temperatures.

PMID- 29445825 TI - Microglial IL-1beta progressively increases with duration of alcohol consumption. AB - Chronic alcohol abuse leads to severe brain damage. Although the underlying neuropathological processes are largely unknown, recent studies show that chronic alcohol consumption leads to neuroinflammation and may result in neurodegeneration and impaired neuronal connectivity. Long-term alcohol consumption promotes the production of pro-inflammatory cytokines, such as TNF alpha and IL-1beta, and activates microglia cells in the brain. As it has not yet been investigated to what extent these processes dependent on the duration of alcohol consumption or whether microglia are source of pro-inflammatory cytokines in vivo, this study investigated the expression of the pro-inflammatory cytokine, IL-1beta, in microglia at different time points in mice chronically exposed to alcohol. In the present study, we exposed mice to 2, 6, and 12 months of alcohol consumption, and using immunohistochemistry, analyzed the expression of the microglial marker, Iba1, together with the pro-inflammatory cytokine IL-1beta in several cortical regions. Moreover, we investigated the effect of pro inflammatory activation of microglia on neuronal density. We found that alcohol drinking progressively enhanced IL-1beta expression in microglia, which was paralleled with an overall increased microglial density after long-term alcohol consumption. However, we did not find changes in the neuronal density or cortical volume after long-term alcohol consumption. These data show that 12 months of alcohol drinking leads to a pro-inflammatory activation of microglia, which may contribute to impaired neuronal connectivity in the cortex. Anti-inflammatory drug treatment during or after chronic alcohol consumption may thus provide a strategy for restoring brain homeostasis.

PMID- 29445826 TI - Genome-Based Comparison of Clostridioides difficile: Average Amino Acid Identity Analysis of Core Genomes. AB - Infections due to Clostridioides difficile (previously known as Clostridium difficile) are a major problem in hospitals, where cases can be caused by community-acquired strains as well as by nosocomial spread. Whole genome sequences from clinical samples contain a lot of information but that needs to be analyzed and compared in such a way that the outcome is useful for clinicians or epidemiologists. Here, we compare 663 public available complete genome sequences of C. difficile using average amino acid identity (AAI) scores. This analysis revealed that most of these genomes (640, 96.5%) clearly belong to the same species, while the remaining 23 genomes produce four distinct clusters within the Clostridioides genus. The main C. difficile cluster can be further divided into sub-clusters, depending on the chosen cutoff. We demonstrate that MLST, either based on partial or full gene-length, results in biased estimates of genetic differences and does not capture the true degree of similarity or differences of complete genomes. Presence of genes coding for C. difficile toxins A and B (ToxA/B), as well as the binary C. difficile toxin (CDT), was deduced from their unique PfamA domain architectures. Out of the 663 C. difficile genomes, 535 (80.7%) contained at least one copy of ToxA or ToxB, while these genes were missing from 128 genomes. Although some clusters were enriched for toxin presence, these genes are variably present in a given genetic background. The CDT genes were found in 191 genomes, which were restricted to a few clusters only, and only one cluster lacked the toxin A/B genes consistently. A total of 310 genomes contained ToxA/B without CDT (47%). Further, published metagenomic data from stools were used to assess the presence of C. difficile sequences in blinded cases of C. difficile infection (CDI) and controls, to test if metagenomic analysis is sensitive enough to detect the pathogen, and to establish strain relationships between cases from the same hospital. We conclude that metagenomics can contribute to the identification of CDI and can assist in characterization of the most probable causative strain in CDI patients. PMID- 29445828 TI - The neural circuits of number and letter copying: an fNIRS study. AB - In our daily lives, we are constantly exposed to numbers and letters. However, it is still under debate how letters and numbers are processed in the brain, while information on this topic would allow for a more comprehensive understanding of, for example, known influences of language on numerical cognition or neural circuits shared by numerical cognition and language processing. Some findings provide evidence for a double dissociation between numbers and letters, with numbers being represented in the right and letters in the left hemisphere, while the opposing view suggests a shared neural network. Since processing may depend on the task, we address the reported inconsistencies in a very basic symbol copying task using functional near-infrared spectroscopy (fNIRS). fNIRS data revealed that both number and letter copying rely on the bilateral middle and left inferior frontal gyri. Only numbers elicited additional activation in the bilateral parietal cortex and in the left superior temporal gyrus. However, no cortical activation difference was observed between copying numbers and letters, and there was Bayesian evidence for common activation in the middle frontal gyri and superior parietal lobules. Therefore, we conclude that basic number and letter processing are based on a largely shared cortical network, at least in a simple task such as copying symbols. This suggests that copying can be used as a control condition for more complex tasks in neuroimaging studies without subtracting stimuli-specific activation.

PMID- 29445830 TI - Bone health assessment in older people with or without muscle health impairment. AB - : This study investigated the relationship between muscle and bone status in elderly individuals. Our results suggested links between sarcopenia and osteoporosis; impairment in muscle status (i.e., muscle mass, muscle strength, and physical performance) is associated with deterioration in bone mass and texture subsequently leading to an increased risk of fracture. INTRODUCTION: Accumulating evidence has shown associations between sarcopenia and osteoporosis, but existing studies face inconsistencies in the clinical definition of both conditions. Thus, we sought to investigate bone health among older individuals with or without muscle health impairment. METHODS: We conducted an analysis of cross-sectional data available from the Sarcopenia and Physical Impairment with Advancing Age (SarcoPhAge) study. Sarcopenia was diagnosed according to the European Working Group on Sarcopenia in Older People (EWGSOP) (i.e., a low muscle mass plus either low muscle strength or low physical performance). Muscle mass and areal bone mineral density (aBMD) were determined using dual-energy X-ray absorptiometry (DEXA). Muscle strength was assessed using a hand dynamometer, and physical performance was assessed with the Short Physical Performance Battery test. Using the cutoff limits proposed by the EWGSOP, we have classified women in the "low SMI group" when its value was < 5.50 kg/m2, in the "low muscle strength group" when strength was < 20 kg, and in the "low physical performance group" when SPPB < 8 points. The thresholds of < 7.26 kg/m2 (for SMI), < 30 kg (for muscle strength), and SPPB < 8 points were used for men. The 10-year fracture risk was obtained using the FRAX(r) tool. Moreover, bone texture was determined using the trabecular bone score (TBS) method. RESULTS: The study sample consisted of 288 older subjects aged 74.7 +/- 5.7 years, and 59.0% of the subjects were women. Sarcopenia was diagnosed in 43 individuals (14.9%), and osteoporosis was diagnosed in 36 subjects (12.5%). Moreover, aBMD values were, most of the time, lower in older men and women with muscle impairment (i.e., low muscle mass, low muscle strength, and low physical performance). For these subjects, we also noted a higher probability of fracture. When comparing bone quality, there were no significant differences in the TBS values between sarcopenic and non-sarcopenic older men and women or between those with low and high muscle mass. However, when controlling for confounders (i.e., age, BMI, number of co-morbidities, smoking status, and nutritional status), TBS values were lower in older women with low muscle strength (p = 0.04) and in older men with low physical performance (p = 0.01). CONCLUSIONS: Our study showed interrelationships between components of sarcopenia and osteoporosis, with older subjects with muscle impairment having poorer bone health. PMID- 29445832 TI - Analytical challenges in sports drug testing. AB - Analytical chemistry represents a central aspect of doping controls. Routine sports drug testing approaches are primarily designed to address the question whether a prohibited substance is present in a doping control sample and whether prohibited methods (for example, blood transfusion or sample manipulation) have been conducted by an athlete. As some athletes have availed themselves of the substantial breadth of research and development in the pharmaceutical arena, proactive and preventive measures are required such as the early implementation of new drug candidates and corresponding metabolites into routine doping control assays, even though these drug candidates are to date not approved for human use. Beyond this, analytical data are also cornerstones of investigations into atypical or adverse analytical findings, where the overall picture provides ample reason for follow-up studies. Such studies have been of most diverse nature, and tailored approaches have been required to probe hypotheses and scenarios reported by the involved parties concerning the plausibility and consistency of statements and (analytical) facts. In order to outline the variety of challenges that doping control laboratories are facing besides providing optimal detection capabilities and analytical comprehensiveness, selected case vignettes involving the follow-up of unconventional adverse analytical findings, urine sample manipulation, drug/food contamination issues, and unexpected biotransformation reactions are thematized. PMID- 29445831 TI - Using a sequential explanatory mixed method to evaluate the therapeutic window of opportunity for initiating osteoporosis treatment following fragility fractures. AB - : Interventions targeting patients with recent fragility fracture and their physician were most successful at initiating osteoporosis treatment during the first 12 months. This window of opportunity had already closed after 1 year. The reasons for declining or accepting the intensive intervention were explored in patients still untreated at 12 months. INTRODUCTION: A fragility fracture (FF) event identifies patients most likely to benefit from osteoporosis treatment. Nonetheless, most FF patients go untreated. Our objective was to determine how long an incident FF remains a strong incentive to initiate osteoporosis treatment. METHODS: A total of 1086 men and women over age 50 with a recent FF event were assigned to either standard care (SC), to minimal (MIN), or intensive (INT) interventions targeting patients and their family physician to initiate osteoporosis treatment. Inpatients with FF (mainly hip) evaluated by rheumatologists were also included in a specialized group (SPE; n = 324). At 1 year, untreated patients in both the SC and the MIN groups were offered an INT intervention. The cohort was followed through 48 months. A qualitative analysis of patient-centered decision-making associated with initiation of treatment was conducted. RESULTS: In MIN and INT groups, osteoporosis treatment was initiated in 41.0 and 54.3% of untreated patients by 12 months, respectively, compared to 68.4% in SPE and 18.9% in SC groups; initiation rates drastically dropped thereafter. Over 4863 patient-years of follow-up, the rates of new FF were 3.4 per 100 patient-years, without significant differences between patients with initial major or minor FF, nor between control or intervention groups. Failure by patients and physicians to recognize FF as a sign of underlying bone disease contributed the most to lack of treatment. CONCLUSION: While incident FFs are an ideal opportunity for starting osteoporosis treatment, 1 year later, the therapeutic window of opportunity has already closed. PMID- 29445833 TI - Functionalized Au@Ag-Au nanoparticles as an optical and SERS dual probe for lateral flow sensing. AB - Lateral flow assay strips (LFASs) with Au nanoparticles (NPs) have been widely used as a probe for biomarkers in point-of-care testing; however, there still remain challenges in detection sensitivity and quantitative analysis. In this study, we developed a surface-enhanced Raman scattering (SERS)-based LFAS for quantitative analysis of a biomarker in the low concentration range. Moreover, apart from conventional Au NPs, three other types of citrate-capped Au-Ag bimetallic NPs: Au core with Ag shell NPs (Au@Ag NPs), rattle-like Au core in Ag Au shell NPs (Au@Ag-Au NPs) and Ag-Au NPs were prepared and functionalized, and their solution-based SERS activities were comprehensively studied by experimental measurement and theoretical analysis. The results clearly indicated that the citrate-capped Au@Ag-Au NPs exhibited the highest SERS activity among the probes tested. Au@Ag-Au NPs were used as both optical and SERS probes in a SERS-based LFAS. In the presence of the analyte at high concentrations, a purple color appeared in the test zone. Highly sensitive and quantitative analysis was realized by measurement of SERS signals from the test lines. One of the most specific markers for cardiac injury, cardiac troponin I (cTnI), was chosen as the detection model. The detection limit of the SERS-based LFAS for cardiac troponin I was 0.09 ng/mL, lowered by nearly 50 times compared with visual results, and could be further lowered by optimization. These results demonstrated that the SERS-based LFAS using citrate-capped Au@Ag-Au NPs as probes can be a powerful tool for highly sensitive and quantitative detection of biomarkers. Graphical abstract A surface-enhanced Raman scattering (SERS)-based lateral flow assay strip using rattle-like Au core in Ag-Au shell (Au@Ag-Au) nanoparticles as probes was developed for quantitative analysis of a biomarker, with a detection limit nearly 50 times lower than that of visual assessment.

AB - Unequivocal assignment of phospholipid peaks in complex mixtures is difficult if only the m/z values but no tandem mass spectrometry (MS/MS) data are available. This is usually the case for matrix-assisted laser/desorption ionization time-of flight (MALDI-TOF) MS imaging experiments and the analysis has normally to be performed without prior separation. Another problem might be the often matrix induced loss of one methyl group in phosphatidylcholine (PC) species, which makes them detectable as negative ions becoming isomers of some phosphatidylethanolamines (PEs). Selected lipid mixtures of known compositions were investigated by negative ion MALDI-TOF MS and various imaging experiments. In addition to common matrices such as 2,5-dihydroxybenzoic acid (DHB) and 9 aminoacridine (9-AA), different binary matrices, including 2,5 dihydroxyacetophenone (2,5-DHAP) as matrix additive to DHB, were tested to probe their performance in both ionization modes. Beside artificial PC and PE mixtures of known compositions, egg yolk and liver extracts as well as cryosections from liver and pancreas tissue were selected as biologically relevant systems. The majority of the binary MALDI matrices used here leads to the loss of a methyl group from PC in the negative ion mode, which makes the clear identification of PE species ambiguous. However, this problem does not apply if a mixture of DHB and 2,5-DHAP is used. Therefore, the application of DHB/2,5-DHAP as matrix is a simple method to unequivocally identify PEs even in complex mixtures and tissue sections as negative ions and without the necessity to separate the individual lipid classes prior to MS detection. Graphical abstract Many common MALDI matrices (such as 9-AA) induce the loss of a methyl group from PC rendering the PC detectable as negative ion. These ions (m/z 744.6 in the upper trace) represent isomers of typical PE species. It will be shown that this problem can be avoided if mixtures between DHB and 2,5-DHAP are applied. At these conditions, POPC is exclusively detectable as a matrix adduct with DHB (at m/z 912.6, lower trace) and does not interfere with PE. This approach can also be used in MALDI MS imaging.

AB - The ability to detect chemical contaminants, including veterinary drug residues in animal products such as fish, is an important example of food safety analysis. In this paper, a liquid chromatography high-resolution mass spectrometry (LC HRMS) screening method using a quadrupole-Orbitrap instrument was applied to the analysis of veterinary drug residues in incurred tissues from aquacultured channel catfish, rainbow trout, and Atlantic salmon and imported aquacultured products including European eel, yellow croaker, and tilapia. Compared to traditional MS methods, the use of HRMS with nontargeted data acquisition and exact mass measurement capability greatly increased the scope of compounds that could be monitored simultaneously. The fish samples were prepared for analysis using a simple efficient procedure that consisted of an acidic acetonitrile extraction followed by solid phase extraction cleanup. Two different HRMS acquisition programs were used to analyze the fish extracts. This method detected and identified veterinary drugs including quinolones, fluoroquinolones, avermectins, dyes, and aminopenicillins at residue levels in fish that had been dosed with those compounds. A metabolite of amoxicillin, amoxicillin diketone, was also found at high levels in catfish, trout, and salmon. The method was also used to characterize drug residues in imported fish. In addition to confirming findings of fluoroquinolone and sulfonamide residues that were found by traditional targeted MS methods, several new compounds including 2-amino mebendazole in eel and ofloxacin in croaker were detected and identified. Graphical Abstract Aquacultured samples are analyzed with a high-resolution mass spectrometry screening method to detect and identify unusual veterinary drug residues including ofloxacin in an imported fish. PMID- 29445836 TI - Bone Loss After Romosozumab/Denosumab: Effects of Bisphosphonates. AB - Romosozumab and denosumab are monoclonal antibodies for the treatment of osteoporosis. Both have a rapid offset of effect resulting in loss of bone density (BMD) gained on-treatment and, in some cases, multiple vertebral fractures following treatment cessation. We recently reported disappointing results from transitioning patients from denosumab to intravenous zoledronate at the time the next denosumab injection is due. The present report re-assesses the role of bisphosphonates following the use of denosumab. In the FRAME trial, osteoporotic women were randomized to romosozumab or placebo for 1 year, then both groups were provided with open-label denosumab for the subsequent 2 years. In women completing this study at our center, we offered treatment with either oral or intravenous bisphosphonates. In the eleven women opting for intravenous treatment, zoledronate was given after a median delay of 65 days from trial-end, in the hope that this might increase skeletal uptake of the drug and, thereby, its efficacy to maintain bone density. In these women, spine BMD was 17.3% above baseline at trial-end, and still 12.3% above baseline a year later, a 73% (CI: 61%, 85%) retention of the treatment benefit. The comparable BMD figures for the total hip were 10.7 and 9.2% above baseline, a 87% (CI: 77%, 98%) retention of treatment effect. In contrast, those not receiving treatment after the conclusion of the FRAME trial lost 80-90% of the BMD gained on-trial in the following 12 months. Women treated with risedronate showed an intermediate response. In the zoledronate group, mean PINP 6 months post-FRAME was 23 +/- 4 ug/L and at 12 months it was 47 +/- 8 ug/L, suggesting that repeat zoledronate dosing is needed at 1 year to maintain the BMD gains. In conclusion, delaying administration of intravenous bisphosphonate when transitioning from short-term denosumab appears to increase the extent to which the gains in BMD are maintained. PMID- 29445837 TI - Alkaline Phosphatases in the Complex Chronic Kidney Disease-Mineral and Bone Disorders. AB - Alkaline phosphatases (APs) remove the phosphate (dephosphorylation) needed in multiple metabolic processes (from many molecules such as proteins, nucleotides, or pyrophosphate). Therefore, APs are important for bone mineralization but paradoxically they can also be deleterious for other processes, such as vascular calcification and the increasingly known cross-talk between bone and vessels. A proper balance between beneficial and harmful activities is further complicated in the context of chronic kidney disease (CKD). In this narrative review, we will briefly update the complexity of the enzyme, including its different isoforms such as the bone-specific alkaline phosphatase or the most recently discovered B1x. We will also analyze the correlations and potential discrepancies with parathyroid hormone and bone turnover and, most importantly, the valuable recent associations of AP's with cardiovascular disease and/or vascular calcification, and survival. Finally, a basic knowledge of the synthetic and degradation pathways of APs promises to open new therapeutic strategies for the treatment of the CKD-Mineral and Bone Disorder (CKD-MBD) in the near future, as well as for other processes such as sepsis, acute kidney injury, inflammation, endothelial dysfunction, metabolic syndrome or, in diabetes, cardiovascular complications. However, no studies have been done using APs as a primary therapeutic target for clinical outcomes, and therefore, AP's levels cannot yet be used alone as an isolated primary target in the treatment of CKD-MBD. Nonetheless, its diagnostic and prognostic potential should be underlined. PMID- 29445838 TI - Psychedelics and related drugs: therapeutic possibilities, mechanisms and regulation.

AB - Mammalian attachment behaviors, such as crying, are essential for infant survival by receiving food, protection, and warmth from caregivers. Ultrasonic vocalization (USV) of infant rodents functions to promote maternal proximity. Impaired USV emission has been reported in mouse models of autism spectrum disorder, suggesting that USV is associated with higher brain function. In utero and lactational dioxin exposure is known to induce higher brain function abnormalities in adulthood; however, whether perinatal dioxin exposure affects behavior during infancy is unclear. Therefore, we studied the impact of dioxin exposure on USV emission in infant mice born to dams treated with 2,3,7,8 tetrachlorodibenzo-p-dioxin (TCDD; 0.6 or 3.0 ug/kg) on gestational day 12.5. On postnatal days 3-9, USVs of the offspring were recorded for 1 min using a microphone in a sound-attenuated chamber. The total USV and mean call durations in infant mice exposed to 3.0 ug/kg, but not 0.6 ug/kg, were shorter than those in the control mice. In addition, the percentages of complicated call types (i.e., chevron and wave) in mice exposed to 3.0 ug/kg were decreased. Dioxin induced gene expression changes occurred in the brains of mice exposed to 3.0 ug/kg; however, body weight, motor activity, and vocal fold structure were not significantly affected. These results suggest that infant USV is a useful behavioral endpoint in developmental neurotoxicity assessment that may be used to evaluate effects of chemical exposure on the infant-caregiver interaction. PMID- 29445840 TI - [Serious adverse events in clinical trials with TAVR and SAVR]. AB - BACKGROUND: The expansion of the transcatheter aortic valve replacement (TAVR) indication towards patients with intermediate surgical risk (Ref. Society of Thoracic Surgeons, STS, score) was analyzed. The aim was to investigate if the complication rates particularly with respect to TAVR and surgical aortic valve replacement (SAVR) concerning patients with intermediate risk are comparable. METHODS: An analysis of serious adverse events (SAEs) and complication rates in clinical trials with TAVR and SAVR of these patients in comparison with high surgical risk patients was performed with the scientific literature and in the Federal Institute for Drugs and Medical Devices (Bundesinstitut fur Arzneimittel und Medizinprodukte, BfArM) database (2012-2017). RESULTS: In several studies for intermediate-risk TAVR patients the published data showed that some complication rates (e. g. mortality) are comparable or better than for intermediate-risk SAVR patients. The analysis of the BfArM database in study 1 (TAVR) resulted in a lower all-cause mortality for intermediate-risk patients (0.9% at 30 days and 7.3% at 1 year post-procedure) than concerning high-risk patients (5.2% at 30 days and 15.7% at 1 year post-procedure). In study 1 the cardiovascular mortality was altogether 11.5% at 4 years post-procedure (9.2% for intermediate and 13.4% for high-risk patients), in study 2 (patients with high-risk) at 4 years it was 15.5% in the TAVR group with slightly lower cardiovascular mortality for SAVR patients with 14.8%. CONCLUSION: In the analysis TAVR interventions have favorable incidences concerning mortality (all-cause and cardiovascular) for intermediate-risk patients. Recently, a transcatheter aortic heart valve with this expanded risk indication received a CE label for the first time in Europe; however, the results of larger clinical studies are relevant for the evaluation (e. g. long-term function over more than 5 years) of TAVR valves for intermediate risk patients.

AB - On November 25, the first national congress for rare diseases in dentistry and oral medicine under the auspices of ACHSE e. V. and Orphanet was held in Muenster. With speakers from the field of medicine, dentistry, politics, patient advocacy groups, self-help groups and persons concerned, a platform for exchange between physicians and patients on an equal footing was offered to the participants. At the end of each of the 12 lectures, more than 300 national and international guests discussed the various issues and perspectives related to the topic of rare diseases in dentistry and oral medicine. Besides the different presentations focusing on dentistry, neuropediatrics, and human genetics, the existing centers for rare diseases, sources of information, European reference networks, and the national action plan for people with rare diseases were the subjects of intensive discussion. The patient perspective was also considered. From now on the congress shall be held in Muenster biennially. PMID- 29445841 TI - Folding and assembly defects of pyruvate dehydrogenase deficiency-related variants in the E1alpha subunit of the pyruvate dehydrogenase complex. AB - The pyruvate dehydrogenase complex (PDC) bridges glycolysis and the citric acid cycle. In human, PDC deficiency leads to severe neurodevelopmental delay and progressive neurodegeneration. The majority of cases are caused by variants in the gene encoding the PDC subunit E1alpha. The molecular effects of the variants, however, remain poorly understood. Using yeast as a eukaryotic model system, we have studied the substitutions A189V, M230V, and R322C in yeast E1alpha (corresponding to the pathogenic variants A169V, M210V, and R302C in human E1alpha) and evaluated how substitutions of single amino acid residues within different functional E1alpha regions affect PDC structure and activity. The E1alpha A189V substitution located in the heterodimer interface showed a more compact conformation with significant underrepresentation of E1 in PDC and impaired overall PDC activity. The E1alpha M230V substitution located in the tetramer and heterodimer interface showed a relatively more open conformation and was particularly affected by low thiamin pyrophosphate concentrations. The E1alpha R322C substitution located in the phosphorylation loop of E1alpha resulted in PDC lacking E3 subunits and abolished overall functional activity. Furthermore, we show for the E1alpha variant A189V that variant E1alpha accumulates in the Hsp60 chaperonin, but can be released upon ATP supplementation. Our studies suggest that pathogenic E1alpha variants may be associated with structural changes of PDC and impaired folding of E1alpha.

AB - Although surgical techniques pertaining to adult spinal deformity (ASD) have advanced over the last decade, proximal junctional kyphosis (PJK) is still a complication following surgery for ASD that continues to significantly challenge clinicians. This article aimed to report on the prevalence of PJK as well as enhance understanding of surgically modifiable and non-modifiable risk factors of PJK to guide management of this postoperative complication of ASD. As the understanding of the pathogenesis as well as surgical modifications aimed at reducing the incidence of PJK have advanced, so too should clinicians' ability to implement more patient-specific operative plans and improve outcomes following realignment surgery for ASD.

AB - KEY MESSAGE: Testcross is the worst mating design to use as a training set to predict maize single-crosses that would be obtained through full diallel or North Carolina design II. Even though many papers have been published about genomic prediction (GP) in maize, the best mating design to build the training population has not been defined yet. Such design must maximize the accuracy given constraints on costs and on the logistics of the crosses to be made. Hence, the aims of this work were: (1) empirically evaluate the effect of the mating designs, used as training set, on genomic selection to predict maize single crosses obtained through full diallel and North Carolina design II, (2) and identify the possibility of reducing the number of crosses and parents to compose these training sets. Our results suggest that testcross is the worst mating design to use as a training set to predict maize single-crosses that would be obtained through full diallel or North Carolina design II. Moreover, North Carolina design II is the best training set to predict hybrids taken from full diallel. However, hybrids from full diallel and North Carolina design II can be well predicted using optimized training sets, which also allow reducing the total number of crosses to be made. Nevertheless, the number of parents and the crosses per parent in the training sets should be maximized.

AB - PURPOSE: This trial assessed if written information on procedural findings and subsequent treatment improved understanding and reduced anxiety among patients undergoing day case flexible cystoscopy (FC). METHODS: Participants completed pre and post-procedure questionnaires self-rating anxiety and feeling well informed on 5-point Likert scales. Supplemental written information was provided after FC to half the patients on a standardized template, according to randomized allocation. Comparisons between the groups were undertaken using the Wilcoxon test. RESULTS: Two hundred patients were recruited, with 171 evaluable questionnaires (83 from written group). The distribution of age, sex and prior FC, as well as the pre-procedure self-assessment of anxiety and understanding, was similar between the two groups. Patients receiving written information reported feeling better informed, with median (range) Likert score of 5 (4-5) compared to 4 (1-5) out of 5 (p < 0.0001) and less anxious (score 1 [1-4] compared to 2 [1-5] out of 5, p < 0.005), although all except four patients had an accurate understanding of the information provided (p = NS). CONCLUSIONS: Written information at the time of FC leads to patients feeling better informed and less anxious, although verbal information alone appears to lead to an adequate understanding.

AB - PURPOSE: Prostatic artery embolization (PAE) has seen a recent increase in interest as a treatment for men with benign prostatic obstruction (BPO). The appeal of this intervention lies in reported reduction in morbidity and its minimally invasive nature. The purpose of this review is to assess the safety and efficacy of PAE as a new treatment in BPO and explore risks surrounding its performance. METHODS: A review of the literature was performed. Medical databases searched included PubMed, EMBASE, and Cochrane databases, limited to English, peer-reviewed articles. Search terms included prostatic artery embolization, lower urinary tracts symptoms, minimally invasive therapies, interventional radiology prostate, and benign prostatic hyperplasia. Articles were screened by two independent reviewers for content on development, methods, outcomes, and complications of PAE. RESULTS: Suitability of patients to undergo PAE depends on review of patient history, pre-procedure visualisation of appropriate vascular anatomy and clinical parameters. Despite this selection of candidates favourable for procedural success, PAE is not without risk of complications, some of which can significantly affect patient quality of life. CONCLUSIONS: Although initial findings show promise regarding safety and efficacy of PAE in improving symptom and quality-of-life scores, further investigation is required to establish durability of effect and the appropriate use of this experimental modality. There is currently limited robust evidence for the beneficial outcomes of PAE. Long term follow-up studies will add to the evidence base to help further assess the feasibility of this procedure as an alternative to TURP.

A total of 110 samplers were distributed throughout the city. Vehicle traffic density, garbage containers and sewers were identified as local emission sources of ammonia. The average ammonia concentrations were 4.66 +/- 2.14 ug/m3 (0.39 11.23 ug/m3 range) in the winter and 5.30 +/- 1.81 ug/m3 (2.33-11.08 ug/m3 range) in the summer. Spatial and seasonal variations of ammonia levels were evaluated. Hotspots were located in the south and center of Madrid City in both winter and summer seasons, with lower ammonia concentrations located in the north (winter) and in the west and east (summer). The number of representative points that were needed to establish a reliable air quality monitoring network for ammonia was determined using a combined clustering and kriging approach. The results indicated that 40 samplers were sufficient to provide a reliable estimate for Madrid City.

AB - In this study, the oxidative damage, antioxidative responses and cadmium (Cd) accumulation in juvenile Silurus meridionalis were studied, after S. meridionalis were exposed to 0 (control), 62.5, 125, 250 and 500 ug Cd/L for 56 days. Cd accumulation, malondialdehyde, superoxide dismutase (SOD), catalase, glutathione (GSH) and total antioxidant capacity (T-AOC) were determined in gill, liver, kidney and intestine tissues. The results showed that the Cd accumulation in S. meridionalis was dose-dependent and tissue-specific, with the highest Cd content in the kidney, followed by the liver, gill, and intestine. Waterborne Cd stress in S. meridionalis was expressed as tissue-specific oxidative damage and antioxidant responses in gill, liver, kidney and intestine tissues. Waterborne Cd exposure induced the most significant oxidative damage in the gill, followed by the liver and kidney, while the intestine showed no sensitivity to waterborne Cd exposure. The antioxidants, such as SOD in the liver, kidney and intestine, as well as T-AOC and GSH in the gill, liver and kidney, were sensitive to waterborne Cd exposure. PMID- 29445850 TI - Factors associated with household food insecurity and depression in pregnant South African women from a low socio-economic setting: a cross-sectional study. AB - PURPOSE: Food insecurity has been linked with maternal depression in low-income settings. Few studies have looked at factors associated with both food insecurity and maternal depression as outcomes. This study aimed to assess factors associated with food insecurity and depression in a sample of pregnant South African women. METHODS: We conducted a cross-sectional study at a Midwife Obstetric Unit in a low-income suburb in Cape Town. Pregnant women attending the clinic for their first antenatal visit were invited to participate. The shortened form of the US Household Food Security Survey Module was used to measure food insecurity. The Expanded Mini-International Neuropsychiatric Interview was used to diagnose depression, anxiety, alcohol and drug dependence, and assess for suicidal ideation and behaviour. Logistic regression modelling was conducted to explore factors associated with food insecurity and depression in separate models. RESULTS: We found that 42% of households were food insecure and that 21% of participants were depressed (N = 376). The odds of being food insecure were increased in women with suicidal behaviour (OR = 5.34; 95% CI 1.26-22.57), with depression (4.27; 1.43-12.70) and in those with three or more children (3.79; 1.25-11.55). The odds of depression was greater in women who were food insecure (5.30; 1.63-17.30), substance dependent (15.83; 1.31-191.48) or diagnosed with an anxiety disorder (5.04; 1.71-14.82). CONCLUSIONS: Food insecurity and depression are strongly associated in pregnant women. The relationship between food insecurity and depression is complex and requires further investigation. Interventions that improve both food security and mental health during the perinatal period are likely to benefit the physical and mental well-being of mothers and children. PMID- 29445851 TI - Beta cell extracellular vesicle miR-21-5p cargo is increased in response to inflammatory cytokines and serves as a biomarker of type 1 diabetes. AB - AIMS/HYPOTHESIS: Improved biomarkers are acutely needed for the detection of developing type 1 diabetes, prior to critical loss of beta cell mass. We previously demonstrated that elevated beta cell microRNA 21-5p (miR-21-5p) in rodent and human models of type 1 diabetes increased beta cell apoptosis. We hypothesised that the inflammatory milieu of developing diabetes may also increase miR-21-5p in beta cell extracellular vesicle (EV) cargo and that circulating EV miR-21-5p would be increased during type 1 diabetes development. METHODS: MIN6 and EndoC-betaH1 beta cell lines and human islets were treated with IL-1beta, IFN-gamma and TNF-alpha to mimic the inflammatory milieu of early type 1 diabetes. Serum was collected weekly from 8-week-old female NOD mice until diabetes onset. Sera from a cross-section of 19 children at the time of type 1 diabetes diagnosis and 16 healthy children were also analysed. EVs were isolated from cell culture media or serum using sequential ultracentrifugation or ExoQuick precipitation and EV miRNAs were assayed. RESULTS: Cytokine treatment in beta cell lines and human islets resulted in a 1.5- to threefold increase in miR-21 5p. However, corresponding EVs were further enriched for this miRNA, with a three to sixfold EV miR-21-5p increase in response to cytokine treatment. This difference was only partially reduced by pre-treatment of beta cells with Z-VAD FMK to inhibit cytokine-induced caspase activity. Nanoparticle tracking analysis showed cytokines to have no effect on the number of EVs, implicating specific changes within EV cargo as being responsible for the increase in beta cell EV miR 21-5p. Sequential ultracentrifugation to separate EVs by size suggested that this effect was mostly due to cytokine-induced increases in exosome miR-21-5p. Longitudinal serum collections from NOD mice showed that EVs displayed progressive increases in miR-21-5p beginning 3 weeks prior to diabetes onset. To validate the relevance to human diabetes, we assayed serum from children with new onset type 1 diabetes compared with healthy children. While total serum miR-21-5p and total serum EVs were reduced in diabetic participants, serum EV miR-21-5p was increased threefold compared with non-diabetic individuals. By contrast, both serum and EV miR-375-5p were increased in parallel among diabetic participants. CONCLUSIONS/INTERPRETATION: We propose that circulating EV miR-21-5p may be a promising marker of developing type 1 diabetes. Additionally, our findings highlight that, for certain miRNAs, total circulating miRNA levels are distinct from circulating EV miRNA content. PMID- 29445852 TI - [Patient education for adults with atopic dermatitis according to the ARNE concept]. AB - Atopic dermatitis (AD) represents a chronic inflammatory skin disease showing a 1 year prevalence of 2-3% during adulthood. In a national randomized, controlled multicenter study initiated by the "Arbeitsgemeinschaft Neurodermitisschulung im Erwachsenenalter" (ARNE, Working Group on Educational Training for Adults with Atopic Dermatitis) a program for structured patient education conducted by a multiprofessional team was developed and evaluated. At 1-year follow-up, coping behavior with respect to itch (assessed by the "Juckreiz-Kognitions-Fragebogen", p < 0.001) and in quality of life (Skindex-29, p < 0.001) significantly improved in patients who had participated in this 12 h patient educational program (n = 168) compared to the waiting control group (n = 147). Moreover, the training led to a significantly greater reduction in disease severity (SCORAD Index, p < 0.001). In this first randomized, controlled multicenter study on effects of patient education in adulthood AD, significant beneficial effects on both psychosocial parameters and the disease severity could be demonstrated. PMID- 29445853 TI - Xylo- and arabinoxylooligosaccharides from wheat bran by endoxylanases, utilisation by probiotic bacteria, and structural studies of the enzymes. AB - Xylooligosaccharides (XOS) and arabinoxylooligosaccharides (AXOS) were produced from the insoluble arabinoxylan fraction of pretreated wheat bran by endoxylanases. The glycoside hydrolase (GH) family 10 xylanases GsXyn10A from Geobacillus stearothermophilus and RmXyn10A-CM from Rhodothermus marinus produced the AXOS A3X, A2XX and A2 + 3XX in addition to XOS. RmXyn10A-CM also produced XA2 + 3XX due to its non-conserved aglycone region accommodating additional arabinose substitutions in subsite +2. The GH11 enzymes, Pentopan from Thermomyces lanuginosus and NpXyn11A from Neocallimastix patriciarum had minor structural differences affecting hydrogen bonds in subsites -3 and +3, with similar hydrolysis profiles producing XA3XX as major AXOS and minor amounts of XA2XX but different ratios of X3/X2. In vitro analysis of the prebiotic properties of (A)XOS produced by Pentopan revealed nearly complete uptake of X2 and X3 by the probiotic bacteria Lactobacillus brevis and Bifidobacterium adolescentis. In contrast to previous reports, the GH43 arabinofuranosidase BaAXHd-3 from B. adolescentis cleaved alpha-1,3-linked arabinose on some single substituted AXOS. PMID- 29445854 TI - Constrained minimization problems for the reproduction number in meta-population models. AB - The basic reproduction number ([Formula: see text]) can be considerably higher in an SIR model with heterogeneous mixing compared to that from a corresponding model with homogeneous mixing. For example, in the case of measles, mumps and rubella in San Diego, CA, Glasser et al. (Lancet Infect Dis 16(5):599-605, 2016. https://doi.org/10.1016/S1473-3099(16)00004-9 ), reported an increase of 70% in [Formula: see text] when heterogeneity was accounted for. Meta-population models with simple heterogeneous mixing functions, e.g., proportionate mixing, have been employed to identify optimal vaccination strategies using an approach based on the gradient of the effective reproduction number ([Formula: see text]), which consists of partial derivatives of [Formula: see text] with respect to the proportions immune [Formula: see text] in sub-groups i (Feng et al. in J Theor Biol 386:177-187, 2015. https://doi.org/10.1016/j.jtbi.2015.09.006 ; Math Biosci 287:93-104, 2017. https://doi.org/10.1016/j.mbs.2016.09.013 ). These papers consider cases in which an optimal vaccination strategy exists. However, in general, the optimal solution identified using the gradient may not be feasible for some parameter values (i.e., vaccination coverages outside the unit interval). In this paper, we derive the analytic conditions under which the optimal solution is feasible. Explicit expressions for the optimal solutions in the case of [Formula: see text] sub-populations are obtained, and the bounds for optimal solutions are derived for [Formula: see text] sub-populations. This is done for general mixing functions and examples of proportionate and preferential mixing are presented. Of special significance is the result that for general mixing schemes, both [Formula: see text] and [Formula: see text] are bounded below and above by their corresponding expressions when mixing is proportionate and isolated, respectively. PMID- 29445855 TI - [Treatment strategy for early stage rectal cancer (T1 carcinoma)]. AB - BACKROUND: A common consensus for the definition for early rectal cancer does not exist. This item is used in cases of histological findings including pTis, pT1 or pT2 tumors. The term early rectal cancer is not mentioned in the German S3 guidelines on colorectal cancer. The pTis tumors are located at the mucosa level of the intestinal wall and they have nearly no tendency to develop metastases but pT2 tumors have a high risk of local metastases; therefore, the term early rectal cancer is not adequate for pT2 tumors. OBJECTIVE: This focus of this article is exclusively on pT1 rectal cancer. Following the histological definition, pT1 tumors of the rectum are located at the level of the mucosa and submucosa of the intestinal wall. CONCLUSION: With respect to the nature of the tumor (e.g. size, grading, invasion of lymphatic and/or blood vessels, Kikuchi classification) local methods (endoscopic procedure, surgical techniques) or radical resections are recommended. Tumor budding is of increasing interest and importance. Depending on the severity of the tumor budding classification (bd1-bd3) there is an association with a more frequent occurrence of lymph node metastases and should therefore be taken into consideration in treatment decisions in the future.

PMID- 29445857 TI - Superior and Anterior Hyoid Displacement During Swallowing in Non-Dysphagic Individuals. AB - The Dynamic Swallow Study (DSS) is a methodology used to objectively and quantitatively assess swallowing kinematics during Videofluoroscopic Swallow Studies (VFSS). No DSS normative data exist delineating superior and anterior hyoid displacement (Hsup and Hant, respectively), nor the ratio between Hsup and Hant (SAratio). The aims of this study were to (1) establish normative data for Hsup, Hant, and SAratio and (2) assess the effects of age, sex, and bolus size on these measures in non-dysphagic patients, within the context of DSS. VFSSs were reviewed for consecutive elderly (>= 65 years) and non-elderly (< 65 years) male and female non-dysphagic patients. Measurements of Hsup, Hant, and SAratio were made using a novel measurement methodology within the context of the Dynamic Swallow Study (DSS) protocol. Statistical analysis was performed to establish interaction effects and main effects of age, sex, and bolus size on Hsup, Hant, and SAratio. Descriptive statistics (mean +/- standard deviations) are outlined for Hsup, Hant, and SAratio. Hsup was significantly effected by bolus size and age. Additionally, a significant three-way interaction of age, sex, and bolus size was observed. Hant was significantly effected by bolus size and sex, but no two- or three-way interactions were present. Neither bolus size, age, nor sex significantly effected SAratio. Age, sex, and bolus size normative data were established for Hsup, Hant, and SAratio for VFSS kinematic analysis. By outlining these measures, one can more thoroughly evaluate the areas of specific swallowing impairment, better determine the therapy targets, and track changes over time. PMID- 29445858 TI - L-Thyroxine intake as a potential risk factor for the development of fatigue in breast cancer patients undergoing chemotherapy. AB - PURPOSE: L-Thyroxine is one of the most commonly prescribed drugs and accordingly used by many breast cancer patients with thyroid disorders. Hence, potential interactions of chemotherapy with L-thyroxine, possibly contributing to fatigue, would be of high clinical relevance. Therefore, we investigated fatigue and underlying pathways in L-thyroxine-using breast cancer patients during chemotherapy. METHODS: Thyroid-stimulating hormone (TSH), L-triiodothyronine (T3), and diurnal salivary cortisol patterns were analyzed in breast cancer patients in the beginning and at the end of adjuvant chemotherapy within the control group (n = 41) of a randomized exercise intervention trial. Additionally, relationships in the exercising group (n = 45) as well as in healthy women (n = 25) were explored. Regression and mediation analyses were performed. RESULTS: L Thyroxine use was significantly associated with lower TSH (median = 0.33 mU/l, interquartile range = (0.15-0.48)), whereas patients not using L-thyroxine had TSH comparable to healthy women (0.51 mU/l (0.37-0.74)). T3 significantly declined during chemotherapy in L-thyroxine users but not in non-users. However, the group difference failed statistical significance. L-Thyroxine treatment was significantly associated with increased physical fatigue during chemotherapy (p = 0.004) in the non-exercising group. This association appeared to be partly mediated by TSH. Further, TSH appeared to affect fatigue partly via increased cortisol levels. In the exercise group, there was no significant association between L-thyroxine and fatigue. CONCLUSIONS: L-Thyroxine treatment during chemotherapy might result in hormonal dysregulations that can contribute to increased physical fatigue. Therefore, breast cancer patients on L-thyroxine treatment may need special monitoring of their thyroid levels and of fatigue during chemotherapy and should be encouraged to exercise.

AB - A new species of Heligmonellidae (Trichostrongylina, Heligmosomoidea), Stilestrongylus kaaguyporai n. sp. is described from the small intestine of Euryoryzomys russatus (Rodentia, Cricetidae, Sigmodontinae) from the Argentine Atlantic Forest, in the Misiones province. The new species was found at Campo Anexo Manuel Belgrano, Reserva de Vida Silvestre Urugua-i and Parque Provincial Urugua-i, with a prevalence of 73% in 15 hosts examined. Stilestrongylus includes 24 Neotropical species, all parasitic in rodents, mostly Sigmodontinae. Stilestrongylus kaaguyporai n. sp. can be differentiated from its congeners by the following characters: caudal bursa dissymmetrical with right lobe larger and pattern of type1-4 in both lobes, rays 6 not forming a lateral trident with rays 4 and 5, rays 8 with dissymmetrical pathway, genital cone hypertrophied with a conspicuous hood-like projection and females with a marked dorso-ventral torsion of the posterior end. This report is the second record of a Stilestrongylus species in E. russatus, increasing to nine the number of parasitic species known from this host. PMID- 29445860 TI - Origin and initiation mechanisms of neuroblastoma. AB - Neuroblastoma is an embryonal malignancy that affects normal development of the adrenal medulla and paravertebral sympathetic ganglia in early childhood. Extensive studies have revealed the molecular characteristics of human neuroblastomas, including abnormalities at genome, epigenome and transcriptome levels. However, neuroblastoma initiation mechanisms and even its origin are long standing mysteries. In this review article, we summarize the current knowledge about normal development of putative neuroblastoma sources, namely sympathoadrenal lineage of neural crest cells and Schwann cell precursors that were recently identified as the source of adrenal chromaffin cells. A plausible origin of enigmatic stage 4S neuroblastoma is also discussed. With regard to the initiation mechanisms, we review genetic abnormalities in neuroblastomas and their possible association to initiation mechanisms. We also summarize evidences of neuroblastoma initiation observed in genetically engineered animal models, in which epigenetic alterations were involved, including transcriptomic upregulation by N-Myc and downregulation by polycomb repressive complex 2. Finally, several in vitro experimental methods are proposed that hopefully will accelerate our comprehension of neuroblastoma initiation. Thus, this review summarizes the state of-the-art knowledge about the mechanisms of neuroblastoma initiation, which is critical for developing new strategies to cure children with neuroblastoma. PMID- 29445861 TI - Bovine neutrophils in health and disease. AB - Bovine neutrophils have similarities to those of other species with respect to mechanisms of their activation and migration into tissue, modulation of immune responses and the balance between microbial killing and host tissue damage. However, bovine neutrophils have biochemical and functional differences from those of other species, which may yield insights about the comparative biology of neutrophils. Neutrophils play protective and harmful roles in the infectious diseases of cattle that occur at times of transition: respiratory disease in beef calves recently arrived to feedlots and mastitis and other diseases of postparturient dairy cows. An important research focus is the mechanisms by which risk factors for these diseases affect neutrophil function and thereby lead to disease and the prospect of genetic or pharmacologic improvement of disease resistance. Further, in keeping with the One Health paradigm, cattle can be considered a model for studying the role of neutrophils in naturally occurring diseases caused by host-adapted pathogens and are thus an intermediary between studies of mouse models and investigations of human disease. Finally, the study of bovine neutrophils is important for agriculture, to understand the pathogenesis of these production-limiting diseases and to develop novel methods of disease prevention that improve animal health and reduce the reliance on antimicrobial use. PMID- 29445862 TI - Hydrodynamic performance of a single-use aerated stirred bioreactor in animal cell culture: applications of tomography, dynamic gas disengagement (DGD), and CFD. AB - The hydrodynamics of gas-liquid two-phase flow in a single-use bioreactor were investigated in detail both experimentally and numerically. Electrical resistance tomography (ERT) and dynamic gas disengagement (DGD) combined with computational fluid dynamics (CFD) were employed to assess the effect of the volumetric gas flow rate and impeller speed on the gas-liquid flow field, local and global gas holdup values, and Sauter mean bubble diameter. From the results obtained from DGD coupled with ERT, the bubble sizes were determined. The experimental data indicated that the total gas holdup values increased with increasing both the rotational speed of impeller and volumetric gas flow rate. Moreover, the analysis of the flow field generated inside the aerated stirred bioreactor was conducted using CFD results. Overall, a more uniform distribution of the gas holdup was obtained at impeller speeds >= 100 rpm for volumetric gas flow rates >= 1.6 * 10 5 m3/s. PMID- 29445863 TI - Use of biological disease modifying antirheumatic drugs in rheumatoid arthritis in Austria from 2008 to 2011 : A retrospective analysis of 72% of the population. AB - BACKGROUND: Rheumatoid arthritis (RA) is the most prevalent chronic inflammatory joint disease. On a national level in Austria, there are currently no data available on how often and which biological disease modifying antirheumatic drugs (bDMARDs) are prescribed in patients with RA. The aim of the present study was to explore prescription patterns of bDMARDs in RA in Austria with a focus on drug survival. METHODS: A retrospective data analysis of bDMARD courses of individual patients with RA that were extracted from the databases of nine Austrian health insurance funds covering 6.1 million (72%) insured people in a 4-year observation period from January 2008 to December 2011. Only patients with first prescriptions of bDMARDs were included. All patients with diagnoses other than RA were excluded. RESULTS: A total of 2906 first prescriptions of bDMARDs were included in the present analysis and 19.35% of RA patients were on bDMARDs in Austria taking into account a prevalence of RA of 0.5%. Tocilizumab showed the longest drug survival after 1 year (73.2%), followed by abatacept which had the longest drug survival after 2 (68.2%) and 3 years (65.2%). The most frequent second bDMARDs switched to were adalimumab (n = 109, 26%), tocilizumab (n = 83, 20%) and etanercept (n = 82, 20%) and 37% of biological DMARDs were prescribed as monotherapy (ranging from 33% with infliximab to 46% with tocilizumab). CONCLUSIONS: Our analysis is based on the largest health care database available in Austria. Tocilizumab and abatacept showed the longest drug survival. Adalimumab, tocilizumab and etanercept were the most frequent DMARDs switched to. Of interest was the high number of bDMARD monotherapies. PMID- 29445864 TI - Playing to your skills: a randomised controlled trial evaluating a dedicated video game for minimally invasive surgery. AB - BACKGROUND: Video gaming demands elements of visual attention, hand-eye coordination and depth perception which may be contiguous with laparoscopic skill development. General video gaming has demonstrated altered cortical plasticity and improved baseline/acquisition of minimally invasive skills. The present study aimed to evaluate for skill acquisition associated with a commercially available dedicated laparoscopic video game (Underground) and its unique (laparoscopic like) controller for the Nintendo(r)Wii UTM console. METHODS: This single-blinded randomised controlled study was conducted with laparoscopically naive student volunteers of limited (< 3 h/week) video gaming backgrounds. Baseline laparoscopic skills were assessed using four basic tasks on the Virtual Reality (VR) simulator (LAP MentorTM, 3D systems, Colorado, USA). Twenty participants were randomised to two groups; Group A was requested to complete 5 h of video gaming (Underground) per week and Group B to avoid gaming beyond their normal frequency. After 4 weeks participants were reassessed using the same VR tasks. Changes in simulator performances were assessed for each group and for intergroup variances using mixed model regression. RESULTS: Significant inter- and intragroup performances were present for the video gaming and controls across four basic tasks. The video gaming group demonstrated significant improvements in thirty-one of the metrics examined including dominant (p <= 0.004) and non dominant (p < 0.050) instrument movements, pathlengths (p <= 0.040), time taken (p <= 0.021) and end score [p <= 0.046, (task-dependent)]. The control group demonstrated improvements in fourteen measures. The video gaming group demonstrated significant (p < 0.05) improvements compared to the control in five metrics. Despite encouraged gameplay and the console in participants' domiciles, voluntary engagement was lower than directed due to factors including: game enjoyment (33.3%), lack of available time (22.2%) and entertainment distractions (11.1%). CONCLUSION: Our work revealed significant value in training using a dedicated laparoscopic video game for acquisition of virtual laparoscopic skills. This novel serious game may provide foundations for future surgical developments on game consoles in the home environment. PMID- 29445865 TI - Risk of recurrence in a homogeneously managed pT3-differentiated thyroid carcinoma population. AB - BACKGROUND: International guidelines for the management of differentiated thyroid cancers are based on the 7th TNM classification: pT3 tumors are defined as differentiated thyroid cancers (DTCs) measuring more than 4 cm in their greatest dimension that are limited to the thyroid or any tumor with minimal extrathyroidal extension (ETE; sternothyroid muscle or perithyroid soft tissues). Differences in clinicohistological features and prognosis among patients with pT3 tumors remain controversial, and studies regarding pT3 subgroups are lacking. OBJECTIVE: To analyze the prognosis of four subgroups of pT3 DTCs (papillary, PTC; or follicular, FTC). DESIGN AND SETTING: The data of patients who underwent surgery for pT3 DTC between 1978 and 2015 in a surgical department specialized in endocrine surgery were reviewed. Patients were classified into four groups as follows: the pT3a (<= 10 mm with ETE), pT3b (10-40 mm with ETE), pT3c (> 40 mm without ETE), and pT3d groups (> 40 mm with ETE). Recurrence-free survival (RFS) was analyzed using the Kaplan-Meier method. RESULTS: One thousand eighty-eight patients with pT3 DTC were included, of whom 311 (29%) had pT3a; 548 (50%), pT3b; 165 (15%), pT3c; and 64 (6%), pT3d. For the 916 patients with lymph node (LN) dissection, metastatic LNs were more frequent in the pT3b and pT3d groups (61 and 61%, respectively) than in the other groups (44% pT3a and 10% pT3c; p < 0.001). During the median follow-up period of 9 years (range, 2-38 years), recurrence occurred in 169 patients with T3 tumors (16%), including 18 with pT3a (6%), 100 with pT3b (18%), 20 with pT3c (12%), and 31 with pT3d (48%). In a multivariate analysis, LN metastases (< 0.0001), extranodal extension (p = 0.03), FTC (vs. PTC) (p = 0.006), pT3b (p = 0.016), and pT3d (p = 0.047) were associated with an increased risk of recurrence. The 5-year RFS rates were 94.5, 82.2, 91.1, and 50.3% for the pT3a, pT3b, pT3c, and pT3d groups, respectively (p < 0.01). CONCLUSION: Except for microcarcinoma, the risk of LN involvement is high and similar for the DTC patients with minimal ETE, regardless of the size of the tumor. The association of a tumor size of > 4 cm and ETE are associated with a poor prognosis and should justify the classification of these cases as a high risk group. Other pT3 patients with no LN metastases could be individualized as a low-risk group.

METHODS: The standardized incidence ratio (SIR) of CCSPC and survival outcomes of EC survivors with and without CCSPC were analyzed using data from January 1 1993 to December 31 2011, obtained from the Korea Central Cancer Registry. RESULTS: Of 14,797 EC survivors, 147 (0.99%) developed CCSPC after an average interval of 5.5 years. The SIR of CCSPC among EC survivors was 2.56, higher than that of colon cancer in the general population. The SIR of CCSPC was highest for the ascending (3.77), followed by the transverse (3.45), descending colon (2.06), and rectum (1.99). The risk of a proximal site of CCSPC was high, especially within 5 years after the diagnosis of EC in the ascending (SIR, 4.37) and transverse (4.91) colon, and in young survivors (< 60 years) in the ascending (5.19) and transverse (3.82) colon. The 5- and 10-year overall survival rates were 84.8 and 80.4% among survivors with EC only and 89.2 and 76.3% for survivors with CCSPC, respectively. CONCLUSIONS: The risk of CCSPC among EC survivors increases especially in the proximal colon in young survivors. These results could be used for surveillance and counseling of EC survivors. PMID- 29445867 TI - Sustained effects of neurofeedback in ADHD: a systematic review and meta analysis. AB - Neurofeedback (NF) has gained increasing interest in the treatment of attention deficit/hyperactivity disorder (ADHD). Given learning principles underlie NF, lasting clinical treatment effects may be expected. This systematic review and meta-analysis addresses the sustainability of neurofeedback and control treatment effects by considering randomized controlled studies that conducted follow-up (FU; 2-12 months) assessments among children with ADHD. PubMed and Scopus databases were searched through November 2017. Within-group and between-group standardized mean differences (SMD) of parent behavior ratings were calculated and analyzed. Ten studies met inclusion criteria (NF: ten studies, N = 256; control: nine studies, N = 250). Within-group NF effects on inattention were of medium effect size (ES) (SMD = 0.64) at post-treatment and increased to a large ES (SMD = 0.80) at FU. Regarding hyperactivity/impulsivity, NF ES were medium at post-treatment (SMD = 0.50) and FU (SMD = 0.61). Non-active control conditions yielded a small significant ES on inattention at post-treatment (SMD = 0.28) but no significant ES at FU. Active treatments (mainly methylphenidate), had large ES for inattention (post: SMD = 1.08; FU: SMD = 1.06) and medium ES for hyperactivity/impulsivity (post: SMD = 0.74; FU: SMD = 0.67). Between-group analyses also revealed an advantage of NF over non-active controls [inattention (post: SMD = 0.38; FU: SMD = 0.57); hyperactivity-impulsivity (post: SMD = 0.25; FU: SMD = 0.39)], and favored active controls for inattention only at pre-post (SMD = - 0.44). Compared to non-active control treatments, NF appears to have more durable treatment effects, for at least 6 months following treatment. More studies are needed for a properly powered comparison of follow-up effects between NF and active treatments and to further control for non-specific effects. PMID- 29445869 TI - Guidelines for management of rheumatic diseases in developing countries from basics to real-world situation: relevance, need, and processes for development. AB - Guidelines or recommendations help to provide uniform standards in medical practice. The development of guidelines requires adherence to pre-defined norms prescribed by different international organizations such as the European League against Rheumatism (EULAR). We searched Pubmed and LILACS to identify published papers in five major rheumatic diseases (rheumatoid arthritis, systemic lupus erythematosus, spondyloarthropathies, osteoarthritis, and scleroderma) from different countries based on their economic prosperity and could find a lack of published literature from most economically weaker regions. Similarly, published guidelines in these rheumatic diseases were sparse from Asia and Africa, which are economically developed to a lesser extent than other regions of the world. Considering differing economic realities driving patient care in different regions of the world, unique challenges in certain geographic areas such as musculoskeletal manifestations of infectious diseases like leprosy and tuberculosis, as well as distinct risk of malignancies and other comorbid conditions, National Rheumatology societies should work towards developing more guidelines for rheumatic diseases from regions such as Asia and Africa, while following strictly the prescribed norms for the same. With a paucity of guidelines for such regions currently, an alternative (although less preferable) suggestion would be that major international societies, whose guidelines are widely read and followed the world over, should consider inputs from experts from diverse regions of the world while developing these guidelines. PMID- 29445868 TI - Induction of systemic resistance in tomato against Botrytis cinerea by N-decanoyl homoserine lactone via jasmonic acid signaling. AB - MAIN CONCLUSION: N-decanoyl-homoserine lactone activates plant systemic resistance against Botrytis cinerea in tomato plants, which is largely dependent on jasmonic acid biosynthesis and signal transduction pathways. Rhizosphere bacteria secrete N-acylated-homoserine lactones (AHLs), a type of specialized quorum-sensing signal molecule, to coordinate their population density during communication with their eukaryotic hosts. AHLs behave as low molecular weight ligands that are sensed by plants and promote the host's resistance against foliar pathogens. In this study, we report on N-decanoyl-homoserine lactone (DHL), which is a type of AHL that induces systemic immunity in tomato plants and protects the host organism against the necrotrophic fungus Botrytis cinerea. Upon DHL treatment, tomato endogenous jasmonic acid (JA) biosynthesis (rather than salicylic acid biosynthesis) and signal transduction were significantly activated. Strikingly, the DHL-induced systemic resistance against B. cinerea was blocked in the tomato JA biosynthesis mutant spr2 and JA signaling gene-silenced plants. Our findings highlight the role of DHL in systemic resistance against economically important necrotrophic pathogens and suggest that DHL-induced immunity against B. cinerea is largely dependent on the JA signaling pathway. Manipulation of DHL-induced resistance is an attractive disease management strategy that could potentially be used to enhance disease resistance in diverse plant species. PMID- 29445870 TI - Extralevator versus standard abdominoperineal excision in locally advanced rectal cancer: a retrospective study with long-term follow-up. AB - PURPOSE: To analyze the results of abdominoperineal excisions (APE) for locally advanced rectal cancer at our institution before and after the adoption of extralevator abdominoperineal excision (ELAPE) with a special reference to long term survival. METHODS: A retrospective cohort study conducted in a tertiary referral center. All consecutive patients operated for locally advanced (TNM classification T3-4) rectal cancer with APE in 2004-2009 were compared to patients with similar tumors operated with ELAPE in 2009-2016. RESULTS: Forty-two ELAPE and 27 APE patients were included. Circumferential resection margin (CRM) was less than 1 mm (R1-resection) in 10 (24%) of ELAPE patients and 11 (41%) of APE patients (p = 0.1358). Intraoperative perforation (IOP) occurred in 4 (10%) patients and 6 (22%) patients in ELAPE and APE groups, respectively (p = 0.1336). There were 3 (7%) local recurrences (LRs) in ELAPE group and 5 (19%) in APE (p = 0.2473). There were no statistical differences in adverse events, overall survival, or disease-free survival between ELAPE and APE groups. CONCLUSIONS: We found a non-significant tendency to lower rates of IOP and positive CRM as well as lower rate of LR in the ELAPE group. Long-term survival and adverse events did not differ between the groups. ELAPE is beneficial for the surgeon in offering better vicinity to the perineal area and better work ergonomics. These technical aspects and the clinically very important tendency to lower rate of LR support the use of ELAPE technique in spite of the lack of survival benefit. PMID- 29445871 TI - Are we doing too much?: local excision before radical surgery in early rectal cancer. AB - PURPOSE: In early rectal cancer cases, the use of local excision is increasing. The general indication for local excision is based on the preoperative stage, but there is often a discrepancy between pre and postoperative stages. We sought to determine the indications for local excision in T1 rectal adenocarcinoma patients by comparing the preoperative clinical and postoperative pathological stages. A second aim was to compare the oncologic outcomes between local excision and radical resection. METHODS: Between 2004 and 2014, 152 T1 rectal adenocarcinoma patients were enrolled. We divided the subjects into two groups, local excision and radical resection, depending on the modality of treatment the patients initially received. The group of patients who underwent radical resection was subsequently subdivided into "excisable" and "non-excisable" groups based on the postoperative pathology. RESULTS: Of 152 patients, 28 patients (18.4%) underwent local excision, while 124 patients (81.6%) underwent radical resection. Of 124 patients, in clinically suspected T2 or less and N0 (93) cases, 50 patients (53.8%) needed treatment beyond local excision, and local excision was sufficient for 43 patients (46.2%). The 3-year overall survival (p = 0.393) and 3-year disease-free survival (p = 0.076) between the local excision and radical resection groups showed no significant difference. CONCLUSIONS: The clinical T stage was overestimated in more than half of the cases. Therefore, if cT1/2 tumors with cN0 are suspected preoperatively, local excision is initially recommended and will allow for determination of underlying pathology. The clinician can then decide whether to monitor or intervene with radical resection. PMID- 29445872 TI - Bowman layer transplantation: 5-year results. AB - PURPOSE: The purpose of this study was to evaluate the 5-year clinical results of isolated Bowman layer (BL) transplantation in the treatment of advanced keratoconus. METHODS: In this prospective, single-center, interventional case series at a tertiary referral center, 20 eyes of 17 patients with advanced keratoconus underwent BL transplantation, i.e. an isolated Bowman layer graft was positioned into a manually dissected mid-stromal pocket. Scheimpflug-based corneal tomography measurements, best corrected spectacle and contact lens visual acuities (BSCVA and BCLVA), endothelial cell density, and complications were evaluated up to 5 years after surgery. RESULTS: Measured simulated and maximum keratometry (Kmean and Kmax) values were stable up to 5 years after surgery (P = .310 and P = .195 for 5 years compared to 1 month follow-up, respectively), following an initial decrease from pre- to 1 month postoperatively (P < .001 each). Mean LogMAR BSCVA remained stable (P > .99), after an initial improvement from pre- to 12 months postoperatively (P = .007). Mean BCLVA did not change from preoperative to 5 years postoperatively (P = .219). During all postoperative follow-ups, mean densitometry values were higher than preoperatively (P < .001). A corneal hydrops occurred in one eye at 4.5 years postoperatively; no other postoperative complications were observed. Kaplan-Meier analysis showed an estimated success rate of 84% at 5 years postoperatively. Endothelial cell density remained stable from before to 5 years after surgery (P = .319). CONCLUSIONS: After early postoperative corneal flattening, topographies were stable up to 5 years after BL transplantation, preserving BCLVA and contact lens tolerance, potentially allowing long term postponement of penetrating or deep anterior lamellar keratoplasty. PMID- 29445873 TI - Maturation of the [Ni-4Fe-4S] active site of carbon monoxide dehydrogenases. AB - Nickel-containing enzymes are diverse in terms of function and active site structure. In many cases, the biosynthesis of the active site depends on accessory proteins which transport and insert the Ni ion. We review and discuss the literature related to the maturation of carbon monoxide dehydrogenases (CODH) which bear a nickel-containing active site consisting of a [Ni-4Fe-4S] center called the C-cluster. The maturation of this center has been much less studied than that of other nickel-containing enzymes such as urease and NiFe hydrogenase. Several proteins present in certain CODH operons, including the nickel-binding proteins CooT and CooJ, still have unclear functions. We question the conception that the maturation of all CODH depends on the accessory protein CooC described as essential for nickel insertion into the active site. The available literature reveals biological variations in CODH active site biosynthesis. PMID- 29445874 TI - New evidence of predation on humans by cookiecutter sharks in Kauai, Hawaii. AB - The feeding patterns of species of large sharks on human corpses are well documented in the literature however, that of smaller sharks are less known. This may introduce uncertainty in the medicolegal conclusions. For that reason, accurate identification of patterns of shark predation is very relevant, specifically in areas bordered by the sea. In the case described here, an unidentified lesion was noted on the body of a victim of a scuba diving accident off the island of Kauai, in Hawaii. The aim of this study was to identify the origin of the lesion and investigate its potential to inform on the context of death and/or decomposition. The original outline of the lesion was digitally reconstructed to enable the collection of measurements which were compared with the literature and interpreted with an interdisciplinary approach. This approach permitted to determine that the macroscopic appearance and dimensions of the lesion (major axis = 3.53 cm) were consistent with a bitemark of a cookiecutter shark (Isistius brasiliensis). It was further determined that the bitemark was incomplete and that the specimen involved had a total length of about 24 cm and was likely to be a juvenile. This is the second report in the published literature of cookiecutter bitemarks on humans in the Hawaiian waters. This study brings new evidence-based insights into the interactions between cookiecutter sharks and human remains in marine environments and provides a valuable contribution to the knowledge base on the topic. PMID- 29445875 TI - Interference screw insertion angle has no effect on graft fixation strength for insertional Achilles tendon reconstruction. AB - PURPOSE: To compare the effect of two interference screw insertion angles on the biomechanical properties of the insertional Achilles tendon (IAT) reconstruction. METHODS: Nine matched pairs of fresh-frozen human cadaveric Achilles tendon specimens were randomized to two groups with interference screw insertion angles of 60 degrees and 120 degrees . The IAT reconstruction was performed by fixing the graft tendon with the interference screw. Each specimen was loaded to failure. The load at failure, stiffness, and mode of failure were documented. Differences in load at failure and stiffness were analysed. RESULTS: There was no statistically significant difference between the 60 degrees and 120 degrees groups for failure load (149.137 +/- 20.836 versus 155.428 +/- 28.343 N, respectively, n.s.) and stiffness (14.523 +/- 2.824 N/mm versus 14.727 +/- 2.192 N/mm, respectively, n.s.). The most common mode of failure was the graft pulling out of the bone tunnel when the screw broke. CONCLUSIONS: Graft fixation at two different interference screw insertion angles for IAT reconstruction exhibited equivalent biomechanical performance. When performing this procedure, surgeons may choose the interference screw insertion angle based on personal preference. PMID- 29445876 TI - Toxicity of PEG-Coated CoFe2O4 Nanoparticles with Treatment Effect of Curcumin. AB - In this work, CoFe2O4 nanoparticles coated with polyethylene glycol (PEG) were successfully synthesized via a hydrothermal technique. Morphological studies of the samples confirmed the formation of polycrystalline pure-phase PEG-CoFe2O4 nanoparticles with sizes of about 24 nm. Toxicity induced by CoFe2O4 nanoparticles was investigated, and biological assays were performed to check the toxicity effects of CoFe2O4 nanoparticles. Moreover, the healing effect of toxicity induced in living organisms was studied using curcumin and it was found that biochemical indexes detoxified and improved to reach its normal level after curcumin administration. Thus, PEG-coated CoFe2O4 synthesized through a hydrothermal method can be utilized in biomedical applications and curcumin, which is a natural chemical with no side effects, can be used for the treatment of toxicity induced by the nanoparticles in living organisms. PMID- 29445877 TI - Sodium lactate improves renal microvascular thrombosis compared to sodium bicarbonate and 0.9% NaCl in a porcine model of endotoxic shock: an experimental randomized open label controlled study. AB - BACKGROUND: Sodium lactate seemed to improve fluid balance and avoid fluid overload. The objective of this study was to determine if these beneficial effects can be at least partly explained by an improvement in disseminated intravascular coagulation (DIC)-associated renal microvascular thrombosis. METHODS: Ancillary work of an interventional randomized open label controlled experimental study. Fifteen female "Large White" pigs (2 months old) were challenged with intravenous infusion of E. coli endotoxin. Three groups of five animals were randomly assigned to receive different fluids: a treatment group received sodium lactate 11.2% (SL group); an isotonic control group received 0.9% NaCl (NC group); a hypertonic control group, with the same amount of osmoles and sodium than SL group, received sodium bicarbonate 8.4% (SB group). Glomerular filtration rate (GFR) markers, coagulation and inflammation parameters were measured over a 5-h period. Immediately after euthanasia, kidneys were withdrawn for histological study. Statistical analysis was performed with nonparametric tests and the Dunn correction for multiple comparisons. A p < 0.05 was considered significant. RESULTS: The direct immunofluorescence study revealed that the percentage of capillary sections thrombosed in glomerulus were significantly lesser in SL group [5 (0-28) %] compared to NC [64 (43-79) %, p = 0.01] and SB [64 (43-79), p = 0.03] groups. Alterations in platelet count and fibrinogen level occurred earlier and were significantly more pronounced in both control groups compared to SL group (p < 0.05 at 210 and 300 min). The increase in thrombin antithrombin complexes was significantly higher in NC [754 (367-945) MUg/mL; p = 0.03] and SB [463 (249-592) MUg/mL; p = 0.03] groups than in SL group [176 (37 265) MUg/mL]. At the end of the experiment, creatinine clearance was significantly higher in SL group [55.46 (30.07-67.85) mL/min] compared to NC group [1.52 (0.17-27.67) mL/min, p = 0.03]. CONCLUSIONS: In this study, we report that sodium lactate improves DIC-associated renal microvascular thrombosis and preserves GFR. These findings could at least partly explain the better fluid balance observed with sodium lactate infusion. PMID- 29445878 TI - Feasibility of intraoperative detection of sentinel lymph nodes with 89-zirconium labelled nanocolloidal albumin PET-CT and a handheld high-energy gamma probe. AB - BACKGROUND: PET/CT lymphoscintigraphy using 89Zr-nanocolloidal albumin has the potential to improve the preoperative identification of sentinel lymph nodes (SLNs), especially if located in the near proximity of the primary tumour. This study aims to demonstrate the feasibility of PET/CT lymphoscintigraphy followed by intraoperative detection of 89Zr-nanocolloidal albumin containing SLNs with the use of a handheld high-energy gamma probe. METHODS: PET/CT lymphoscintigraphy was performed after peritumoural injection of 89Zr-nanocolloidal albumin in five patients with oral cavity carcinoma planned for surgical resection. SLN biopsy procedure was performed 18 h later. SLNs were detected using detailed information of PET/CT and the high-energy gamma probe. RESULTS: In all patients, SLNs were identified on PET/CT lymphoscintigraphy. Intraoperative detection using the high energy gamma probe was possible in 10 of 13 SLNs, at a short distance from the SLN. CONCLUSIONS: This study demonstrates that intraoperative detection of SLNs containing 89Zr-nanocolloidal albumin using a handheld high-energy gamma probe is feasible, but its clinical use and sensitivity seem to be limited. TRIAL REGISTRATION: CCMO NL37222.092.11. PMID- 29445879 TI - Role of Thioredoxin in Age-Related Hypertension. AB - PURPOSE OF REVIEW: Although the roles of oxidant stress and redox perturbations in hypertension have been the subject of several reviews, role of thioredoxin (Trx), a major cellular redox protein in age-related hypertension remains inadequately reviewed. The purpose of this review is to bring readers up-to-date with current understanding of the role of thioredoxin in age-related hypertension. RECENT FINDINGS: Age-related hypertension is a major underlying cause of several cardiovascular disorders, and therefore, intensive management of blood pressure is indicated in most patients with cardiovascular complications. Recent studies have shown that age-related hypertension was reversed and remained lowered for a prolonged period in mice with higher levels of human Trx (Trx-Tg). Additionally, injection of human recombinant Trx (rhTrx) decreased hypertension in aged wild-type mice that lasted for several days. Both Trx-Tg and aged wild type mice injected with rhTrx were normotensive, showed increased NO production, decreased arterial stiffness, and increased vascular relaxation. These studies suggest that rhTrx could potentially be a therapeutic molecule to reverse age related hypertension in humans. The reversal of age-related hypertension by restoring proteins that have undergone age-related modification is conceptually novel in the treatment of hypertension. Trx reverses age-related hypertension via maintaining vascular redox homeostasis, regenerating critical vasoregulatory proteins oxidized due to advancing age, and restoring native function of proteins that have undergone age-related modifications with loss-of function. Recent studies demonstrate that Trx is a promising molecule that may ameliorate or reverse age-related hypertension in older adults. PMID- 29445881 TI - Study of salivary and serum vaspin and total antioxidants in anorexia nervosa. AB - OBJECTIVES: Patients with anorexia nervosa (AN) are primarily at high risk of multiple somatic complications, including oral diseases. In recent years, a number of new molecules that may play a potentially important role in AN progress and prognosis have been identified in saliva, but their exact roles are still poorly understood. Two such group of substances are antioxidants and vaspin. The purpose of this observational, cross-sectional study was to measure both the salivary and serum total antioxidant status (TAS), and vaspin (VASP) concentrations of patients with AN in comparison to an average population. MATERIAL AND METHODS: Ninety subjects participated (30 patients with AN, 60 matched healthy control subjects). A clinical examination was made, and blood and salivary samples were taken during the acute stage of AN (BMI < 15 kg/m2) in the first week of hospitalization. Enzyme immunoassay (ELISA) suitable for measuring VASP and colorimetric assay for TAS were used. RESULTS: Anorexic patients had significant reductions in salivary flow, TAS, and an elevation in VASP levels in their saliva and serum. Significant correlations between TAS, VASP, salivary flow, and nutritional status were detected. CONCLUSION: Determination of TAS and VASP in combined biological material confirmed that saliva might be a reliable non-invasive source of information for potent nutritional biomarkers. CLINICAL RELEVANCE: Our findings suggest that VASP cannot be excluded, as its increased concentration in saliva is an adaptive mechanism in reduced TAS, one resulting from diminished salivary secretion. It is therefore worth conducting further research aimed at recognizing the role of TAS and VASP in the saliva of underweight patients. PMID- 29445882 TI - Procedure rates performed by emergency medicine residents: a retrospective review. AB - BACKGROUND: The purpose of our study is to investigate rates of individual procedures performed by residents in our emergency medicine (EM) residency program. Different programs expose residents to different training environments. Our hypothesis is that ultrasound examinations are the most commonly performed procedure in our residency. METHODS: The study took place in an academic level I trauma center with multiple residency and fellowship programs including surgery, surgical critical care, trauma, medicine, pulmonary/critical care, anesthesiology and others. Also, the hospital provides a large emergency medical services program providing basic and advanced life support and critical care transport, which is capable of performing rapid sequence intubation. Each EM residency class, except for the first 2 months of the inaugural class, used New Innovations to log procedures. New Innovations is an online database for tracking residency requirements, such as procedures and hours. For the first 3 months, procedures were logged by hand on a log sheet. In addition, our department has a wireless electronic system (Qpath) for recording and logging ultrasound images. These logs were reviewed retrospectively without any patient identifiers. Actual procedures and simulation procedures were combined for analysis as they were only logged separately halfway through the study period. Procedures were summed and the average procedure rate per resident per year was calculated. RESULTS: In total, 66 full resident years were analyzed. Overall, ultrasound was the most commonly performed procedure, with each resident performing 125 ultrasounds per year. Removing "resuscitations," the second most common was endotracheal intubation, performed 28.91 times per year, and third most was laceration repair, which was performed 17.39 times per year. Our lowest performed procedure was thoracentesis, which was performed on average 0.11 times per resident per year. CONCLUSIONS: Residents performed a variety of procedures each year. Ultrasound examinations were the most frequent procedure performed. The number of ultrasound procedures performed may reflect the changing training landscape and influence future Accreditation Council of Graduate Medical Education requirements. PMID- 29445880 TI - The headache under-response to treatment (HURT) questionnaire, an outcome measure to guide follow-up in primary care: development, psychometric evaluation and assessment of utility. AB - BACKGROUND: Headache disorders are both common and burdensome but, given the many people affected, provision of health care to all is challenging. Structured headache services based in primary care are the most efficient, equitable and cost-effective solution but place responsibility for managing most patients on health-care providers with limited training in headache care. The development of practical management aids for primary care is therefore a purpose of the Global Campaign against Headache. This manuscript presents an outcome measure, the Headache Under-Response to Treatment (HURT) questionnaire, describing its purpose, development, psychometric evaluation and assessment for clinical utility. The objective was a simple-to-use instrument that would both assess outcome and provide guidance to improving outcome, having utility across the range of headache disorders, across clinical settings and across countries and cultures. METHODS: After literature review, an expert consensus group drawn from all six world regions formulated HURT through item development and item reduction using item-response theory. Using the American Migraine Prevalence and Prevention Study's general-population respondent panel, two mailed surveys assessed the psychometric properties of HURT, comparing it with other instruments as external validators. Reliability was assessed in patients in two culturally-contrasting clinical settings: headache specialist centres in Europe (n = 159) and primary care centres in Saudi Arabia (n = 40). Clinical utility was assessed in similar settings (Europe n = 201; Saudi Arabia n = 342). RESULTS: The final instrument, an 8-item self-administered questionnaire, addressed headache frequency, disability, medication use and effect, patients' perceptions of headache "control" and their understanding of their diagnoses. Psychometric evaluation revealed a two-factor model (headache frequency, disability and medication use; and medication efficacy and headache control), with scale properties apparently stable across disorders and correlating well and in the expected directions with external validators. The literature review found few instruments linking assessment to clinical advice or suggested actions: HURT appeared to fill this gap. In European specialist care, it showed utility as an outcome measure across headache disorders. In Saudi Arabian primary care, HURT (translated into Arabic) was reliable and responsive to clinical change. CONCLUSIONS: With demonstrated validity and clinical utility across disorders, cultures and settings, HURT is available for clinical and research purposes. PMID- 29445883 TI - Neurological Complications of Acute and Chronic Otitis Media. AB - PURPOSE OF REVIEW: The aim of this study is to discuss the symptoms, diagnosis, and management of the neurologic complications of acute and chronic otitis media. RECENT FINDINGS: Antibiotic therapy has greatly reduced the frequency of complications of otitis media. However, it is of vital importance to remain aware of the possible development of neurologic complications. There is a trend toward less severe presenting symptoms including otorrhea, headache, nausea, and fever, with altered mental status and focal neurologic deficits presenting later. In order to reduce morbidity, early deployment of a multidisciplinary approach with prompt imaging and laboratory studies is imperative to guide appropriate management. Complications of acute and chronic otitis media may present with neurologic signs and symptoms. It is important to recognize the possible otitic origin of such complications to ensure proper management and to decrease overall morbidity and mortality. PMID- 29445884 TI - Acute kidney injury epidemiology, risk factors, and outcomes in critically ill patients 16-25 years of age treated in an adult intensive care unit. AB - BACKGROUND: Most studies of acute kidney injury (AKI) have focused on older adults, and little is known about AKI in young adults (16-25 years) that are cared for in an adult intensive care unit (ICU). We analyzed data from a large single-center ICU database and defined AKI using the Kidney Disease Improving Global Outcomes criteria. We stratified patients 16-55 years of age into four age groups for comparison and used multivariable logistic regression to identify associations of potential susceptibilities and exposures with AKI and mortality. RESULTS: AKI developed in 52.6% (n = 8270) of the entire cohort and in 39.8% of the young adult age group (16-25 years). The AUCs for the age categories were similar at 0.754, 0.769, 0.772, and 0.770 for the 16-25-, 26-35-, 36-45-, and 45 55-year age groups, respectively. For the youngest age group, diabetes (OR 1.89; 95% CI 1.09-3.29), surgical reason for admission (OR 1.79; 95% CI 1.44-2.23), severity of illness (OR 1.02; 95% CI 1.02-1.03), hypotension (OR 1.13; 95% CI 1.04-1.24), and certain medications (vancomycin and calcineurin inhibitors) were all independently associated with AKI. AKI was a significant predictor for longer length of stay, ICU mortality, and mortality after discharge. CONCLUSIONS: AKI is a common event for young adults admitted to an adult tertiary care center ICU with an associated increased length of stay and risk of mortality. Potentially modifiable risk factors for AKI including medications were identified for all stratified age groups. PMID- 29445886 TI - Infinite dilution activity coefficient from SMD calculations: accuracy and performance for predicting liquid-liquid equilibria. AB - Prediction of liquid-liquid phase equilibria is an important goal in the physical chemistry of solutions. Quantum chemistry methods, combined with a dielectric continuum description of the solvent, has received attention as a first principle approach. In this work, the performance of the continuum solvation model based on density (SMD) for prediction of gammainfinity in binary liquid mixtures, using 46 values of gammainfinity, was evaluated. We found the mean uncertainty of RTln gammainfinity to be 0.92 kcal mol-1. Based on the calculated gammainfinity and the two parameters of the Redlich-Kister expansion, we calculated the liquid liquid phase equilibria. Based on 26 values of solubility, an uncertainty of 0.66 was found in the logarithm of molar fraction of the smallest component in each phase. Our results suggest this approach can be used for fast and semi quantitative prediction of phase behavior. More reliable predictions could be obtained with improvements in the SMD model. Graphical abstract Prediction of liquid-liquid phase equilibria?. PMID- 29445885 TI - The Interplay of Lipids, Lipoproteins, and Immunity in Atherosclerosis. AB - PURPOSE OF REVIEW: Atherosclerosis is an inflammatory disorder of the arterial wall, in which several players contribute to the onset and progression of the disease. Besides the well-established role of lipids, specifically cholesterol, and immune cell activation, new insights on the molecular mechanisms underlying the atherogenic process have emerged. RECENT FINDINGS: Meta-inflammation, a condition of low-grade immune response caused by metabolic dysregulation, immunological memory of innate immune cells (referred to as "trained immunity"), cholesterol homeostasis in dendritic cells, and immunometabolism, i.e., the interplay between immunological and metabolic processes, have all emerged as new actors during atherogenesis. These observations reinforced the interest in directly targeting inflammation to reduce cardiovascular disease. The novel acquisitions in pathophysiology of atherosclerosis reinforce the tight link between lipids, inflammation, and immune response, and support the benefit of targeting LDL-C as well as inflammation to decrease the CVD burden. How this will translate into the clinic will depend on the balance between costs (monoclonal antibodies either to PCSK9 or to IL-1beta), side effects (increased incidence of death due to infections for anti-IL-1beta antibody), and the benefits for patients at high CVD risk. PMID- 29445887 TI - Lung volumes and lung volume recruitment in ARDS: a comparison between supine and prone position. AB - BACKGROUND: The use of positive end-expiratory pressure (PEEP) and prone position (PP) is common in the management of severe acute respiratory distress syndrome patients (ARDS). We conducted this study to analyze the variation in lung volumes and PEEP-induced lung volume recruitment with the change from supine position (SP) to PP in ARDS patients. METHODS: The investigation was conducted in a multidisciplinary intensive care unit. Patients who met the clinical criteria of the Berlin definition for ARDS were included. The responsible physician set basal PEEP. To avoid hypoxemia, FiO2 was increased to 0.8 1 h before starting the protocol. End-expiratory lung volume (EELV) and functional residual capacity (FRC) were measured using the nitrogen washout/washin technique. After the procedures in SP, the patients were turned to PP and 1 h later the same procedures were made in PP. RESULTS: Twenty-three patients were included in the study, and twenty were analyzed. The change from SP to PP significantly increased FRC (from 965 +/- 397 to 1140 +/- 490 ml, p = 0.008) and EELV (from 1566 +/- 476 to 1832 +/- 719 ml, p = 0.008), but PEEP-induced lung volume recruitment did not significantly change (269 +/- 186 ml in SP to 324 +/- 188 ml in PP, p = 0.263). Dynamic strain at PEEP decreased with the change from SP to PP (0.38 +/- 0.14 to 0.33 +/- 0.13, p = 0.040). CONCLUSIONS: As compared to supine, prone position increases resting lung volumes and decreases dynamic lung strain. PMID- 29445888 TI - Addressing Molecular Diagnosis of Occupational Allergies. AB - PURPOSE OF REVIEW: Numerous clinically relevant allergenic molecules enhance the performance of specific (s) IgE tests and improve the specificity of allergy diagnosis. This review aimed to summarize our current knowledge of the high molecular-weight allergens involved in the development of occupational asthma and rhinitis and to critically analyze the contribution of component-resolved diagnosis in the management of these conditions. RECENT FINDINGS: There is a lack of standardization and validation for most available extracts of occupational agents, and assessment of sIgE reactivity to occupational allergen components has been poorly investigated, with the notable exception of natural rubber latex (NRL) and wheat flour. In the case of NRL, the application of recombinant single allergens and amplification of natural extracts with stable recombinant allergens improved the test sensitivity. IgE-sensitization profile in patients with baker's asthma showed great interindividual variation, and extract-based diagnostic is still recommended. For other occupational allergens, it remains necessary to evaluate the relevance of single allergen molecules for the sensitization induced by occupational exposure. Progress has been made to characterize occupational allergens especially NRL and wheat, although there is still an unmet need to increase the knowledge of occupational allergens, to include standardized tools into routine diagnostic, and to evaluate their usefulness in clinical practice. PMID- 29445889 TI - Clinical significance of circulating tumor cells from lung cancer patients using microfluidic chip. AB - Circulating tumor cells (CTCs) exist in the peripheral blood and have an important role in the disease development, tumor metastasis and clinical surveillance, especially in the process of metastasis. However, the technology of detecting CTCs still had a large challenge since they were rare in the peripheral blood. Here, we developed a size-based microfluidic chip, which contained array and filter channel array that could enrich CTCs from blood samples more quickly and conveniently. Combined with clinical specimen, we analyzed CTCs in 200 lung cancer patients by this microfluidic chip. The microfluidic device has high specificity and sensitivity in detecting CTCs (86.0% sensitivity and 98% specificity). Furthermore, the number of CTCs showed a increasing trend according to the stage of the disease (the mean number of I stage 5.0 +/- 5.121 versus II stage 8.731 +/- 6.36 versus III stage 16.81 +/- 9.556 versus IV stage 28.72 +/- 17.39 cells/mL, P < 0.05). The number of CTCs was concurrent with the condition of pathological type and metastasis patients. Compared to conventional markers like CEA, CY211, SCC, CTCs showed a higher positive rate in diagnosed patients. The advanced microfluidic device could capture tumor cells without reliance on cell surface expression markers and provide a fast, convenient, economical method in detecting CTCs, thereby offering potential to design effective and individualized cancer therapies. PMID- 29445890 TI - Benign endometrial proliferations mimicking malignancies: a review of problematic entities in small biopsy specimens. AB - Benign proliferations that mimic malignancies are commonly encountered during the course of assessment of small and fragmented endometrial samples. Although benign, endometrial epithelial metaplasias often coexist with premalignant or malignant lesions causing diagnostic confusion. The difficulty with mucinous metaplasia lies in its distinction from atypical mucinous glandular proliferations and mucinous carcinomas, which are associated with significant interobserver variability. Papillary proliferation of the endometrium is commonly associated with hormonal drugs and endometrial polyps and is characterised by papillae with fibrovascular cores covered by epithelial cells without cytologic atypia. They are classified into simple or complex papillary proliferations depending on the architectural complexity and extent of proliferation. Complex papillary proliferations are associated with a high risk of concurrent or subsequent hyperplasia with atypia/carcinoma. Papillary proliferations may have coexisting epithelial metaplasias and, most commonly, mucinous metaplasia and syncytial papillary change. Those with striking mucinous metaplasia overlap morphologically with papillary mucinous metaplasia. The latter has been proposed as a precursor of endometrial mucinous carcinoma. Misinterpreting the Arias Stella reaction as a malignant or premalignant lesion is more likely to occur if the pathologist is unaware that the patient is pregnant or on hormonal drugs. Endometrial hyperplasia with secretory changes may occasionally be difficult to distinguish from the torturous and crowded glands of a late secretory endometrium. Endometrial polyps may have abnormal features that can be misinterpreted as endometrial hyperplasia or Mullerian adenosarcoma. Awareness of these benign endometrial proliferations and their common association with hormonal medication or altered endogenous hormonal levels will help prevent the over-diagnosis of premalignant and malignant lesions. PMID- 29445892 TI - Performance evaluation of nonhomogeneous hospitals: the case of Hong Kong hospitals. AB - Throughout the world, hospitals are under increasing pressure to become more efficient. Efficiency analysis tools can play a role in giving policymakers insight into which units are less efficient and why. Many researchers have studied efficiencies of hospitals using data envelopment analysis (DEA) as an efficiency analysis tool. However, in the existing literature on DEA-based performance evaluation, a standard assumption of the constant returns to scale (CRS) or the variable returns to scale (VRS) DEA models is that decision-making units (DMUs) use a similar mix of inputs to produce a similar set of outputs. In fact, hospitals with different primary goals supply different services and provide different outputs. That is, hospitals are nonhomogeneous and the standard assumption of the DEA model is not applicable to the performance evaluation of nonhomogeneous hospitals. This paper considers the nonhomogeneity among hospitals in the performance evaluation and takes hospitals in Hong Kong as a case study. An extension of Cook et al. (2013) [1] based on the VRS assumption is developed to evaluated nonhomogeneous hospitals' efficiencies since inputs of hospitals vary greatly. Following the philosophy of Cook et al. (2013) [1], hospitals are divided into homogeneous groups and the product process of each hospital is divided into subunits. The performance of hospitals is measured on the basis of subunits. The proposed approach can be applied to measure the performance of other nonhomogeneous entities that exhibit variable return to scale. PMID- 29445891 TI - Immunohistochemical analysis and prognostic significance of PD-L1, PD-1, and CD8+ tumor-infiltrating lymphocytes in Ewing's sarcoma family of tumors (ESFT). AB - Ewing's sarcoma family of tumors (ESFT) are aggressive neoplasms with scant tumor infiltrating lymphocytes. We analyzed the immunohistochemical (IHC) expression of PD-L1 and PD-1 and their prognostic significance in clinically localized neoplasms in a cohort of 370 ESFT. Slides prepared from tissue microarrays were stained for PD-L1, PD-1, and CD8. Membranous/cytoplasmic staining over 5% of tumor cells was regarded as positive for PD-L1 and PD-1. Prognostic analysis was done considering only clinically localized tumors (n = 217). PD-L1 expression was present in 19% of ESFT, while PD-1 was expressed in 26%. Forty-eight percent of tumors were negative and 12% were positive for both PD-L1 and PD-1. Metastatic tumors displayed higher expression of PD-L1 (p < 0.0001). Histological subtypes were not correlated with PD-L1 or PD-1 positivity. ESFT with elevated proliferation index (Ki-67) were associated with higher PD-L1 expression (p = 0.049). Regarding prognosis, no significant association was found between PD-L1 expression and progression-free survival (PFS) or overall survival (OS), whereas lack of PD-1 expression in tumor cells was correlated with both poor PFS (p = 0.02) and poor OS (p = 0.004). Tumor-infiltrating CD8(+) T lymphocytes were observed in 15.4% of ESFT with informative results (347 tumors). No correlation was found between tumor-infiltrating CD8(+) T lymphocytes and ESFT histological subtypes, tumor location, or PD-1 and PD-L1 expression, nor with PFS (p = 0.473) or OS (p = 0.087). PD-L1 expression was not significantly related to prognosis. PD-1 was expressed in 26% of ESFT tumor cells and may have prognostic and therapeutic implications. CD8 expression in tumor-infiltrating lymphocytes was not related to prognosis. PMID- 29445893 TI - Nestin expression is differently regulated between odontoblasts and the subodontoblastic layer in mice. AB - The Nestin gene encodes type VI intermediate filament and is known to be expressed in undifferentiated cells during neurogenesis and myogenesis. To regulate Nestin expression, the first or second intron enhancer is activated in a tissue-dependent manner, for example, the former in mesodermal cells and the latter in neural stem cells. Although Nestin has also been used as a differentiation marker for odontoblasts during tooth development, how Nestin expression is regulated in odontoblasts remains unclear. Therefore, this study aimed to compare the expression patterns of Nestin-GFP (green fluorescent protein) with that of endogenous Nestin in developing teeth of Nestin-EGFP (enhanced GFP) transgenic mice, in which the second intron enhancer is connected with the EGFP domain, at postnatal 7d, 3w, and 8w. Immunohistochemical and in situ hybridization analyses revealed that endogenous Nestin protein and Nestin mRNA were intensely expressed in differentiated odontoblasts, while GFP immunoreactivity, which reflects the activity of Nestin second intron enhancer mediated transcription, was mainly observed in the subodontoblastic layer. These results indicate that the first intron enhancer may be activated in differentiated odontoblasts. Intriguingly, Nestin-GFP expression in the subodontoblastic layer was found to be restricted to the coronal pulp of molars, which is susceptible to tooth injuries. Because the subodontoblastic layer serves as a reservoir of newly differentiated odontoblast-like cells upon exogenous stimuli to dentin, our findings suggest that the original odontoblasts and regenerated odontoblast-like cells may differently regulate Nestin expression. PMID- 29445894 TI - Sparse QSAR modelling methods for therapeutic and regenerative medicine. AB - The quantitative structure-activity relationships method was popularized by Hansch and Fujita over 50 years ago. The usefulness of the method for drug design and development has been shown in the intervening years. As it was developed initially to elucidate which molecular properties modulated the relative potency of putative agrochemicals, and at a time when computing resources were scarce, there is much scope for applying modern mathematical methods to improve the QSAR method and to extending the general concept to the discovery and optimization of bioactive molecules and materials more broadly. I describe research over the past two decades where we have rebuilt the unit operations of the QSAR method using improved mathematical techniques, and have applied this valuable platform technology to new important areas of research and industry such as nanoscience, omics technologies, advanced materials, and regenerative medicine. This paper was presented as the 2017 ACS Herman Skolnik lecture. PMID- 29445895 TI - On reprogramming of tumor cells metabolism: detection of glycogen in the cell lines of hepatocellular origin with various degrees of dedifferentiation. AB - The reprogramming of cancer cells includes shifts in glucose and glycogen metabolism. The aim of our work was to check the ability of forming glycogen grains in hepatocellular tumor cell lines of various dedifferentiation levels. We studied the monolayer culture established in vitro after explanting cells from rat ascites Zajdela hepatoma strain C (ZH-C) as a "parental" line and its five daughter clonal sublines: the holoclonal sublines 3H, 5F, 6H and the meroclonal ones 1E, 9C, which possess, respectively, the properties of cancer stem-like cells (CSLCs) and cancer progenitor-like cells (CPLCs). Besides, we studied four permanent cell lines of a rat hepatoma HTC, two murine hepatomas BWTG3 and MH 22a, and human hepatoblastoma HepG2. We used normal rat hepatocytes as positive control cells that form glycogen. We estimated relative cell dedifferentiation levels of the studied lines via analysis of cell morphology, morphometry and motility character on stained cell preparations and lifetime video files. Glycogen in the cells was detected using a Schiff type Au-SO2 reagent. All studied hepatocellular tumor lines were not of equal dedifferentiation level as manifested by different nucleus-to-cytoplasm ratio, by epithelium-like or fibroblast-like morphology, by tight or loosen intercellular contacts, by cell migration of collective or individual types. Glycogen fluorescence of uneven intensity was observed in all normal rat hepatocytes, but only in some cell groups or in single cells of hepatocellular tumor lines. The large or small fluorescent grains were found not only in relatively less dedifferentiated parental ZH-C line, BWTG3 and HepG2 lines, but also in moderately dedifferentiated 1E and HTC lines and even in severely dedifferentiated 3H, 5F and 6H sublines, as well as in the islets of the rat ascites hepatoma induced in vivo by the injection of 3H cells (the tumor-initiating cells). On the other hand, MH-22 and 9C lines, being relatively less and moderately dedifferentiated, showed no glycogen fluorescence. Thus, in 10 tumor cell lines of hepatocellular origin, an ability to reserve glycogen manifested no obvious dependency on their dedifferentiation level. Glycogen grains were detected in some cells even of the severely dedifferentiated lines: in single CSLCs of holoclonal ZH sublines grown in vitro and in a majority of tumor-initiating cells derived from ascites hepatoma in vivo. We suggest that dynamic changes in glycogen formation in CSLCs and tumor-initiating cells might be of importance for their dedifferentiation, self-renewal in vitro, survival and metastasis in vivo. The role of glycogen in maintaining viability and metastasis of tumor cells is to be further studied. PMID- 29445896 TI - GLP-1 Receptor Agonists and Cardiovascular Disease: a Meta-Analysis of Recent Cardiac Outcome Trials. AB - PURPOSE: The aim of this study is to examine the cardioprotective properties of Glucagon-like peptide-1 receptor agonist, a class of antihyperglycemic therapy, via meta-analysis of four recently published cardiovascular outcomes trials. METHODS: Meta-analysis was performed pooling data from the ELIXA, LEADER, SUSTAIN 6 and EXSCEL trials. A random effects model was used to generate risk ratio with 95% confidence interval for cardiovascular and safety outcomes. RESULTS: A total of 33,457 patients were included in the meta-analysis. Based on the study, GLP-1R agonists significantly reduced all-cause mortality (RR 0.89; 95% CI 0.82 to 0.96) and cardiovascular mortality (RR 0.88; 95% CI 0.80 to 0.97) when compared to placebo. When long-acting agents were analyzed alone, reduction in major adverse cardiac events (RR 0.88; 95% CI 0.81 to 0.97) and non-fatal strokes (RR 0.87; 95% CI 0.76 to 0.99) also showed significance. CONCLUSION: Overall, GLP-1R agonists appear to have cardioprotective properties likely via modification of metabolic parameters such as glycemic control, weight loss, and improvement in blood pressure. Additional studies are warranted to compare cardiovascular outcomes among the different agents. PMID- 29445897 TI - BrdU/EdU dual labeling to determine the cell-cycle dynamics of defined cellular subpopulations. AB - Measuring the mean duration of synthesis-phase (Ts) and of the total cell-cycle (Tc) within progenitor cell populations can provide important insights into the biology governing these cells. Rather than a passive process that shows little variability across cellular contexts, the cell-cycle is instead highly regulated. For example, in the rodent forebrain, Ts is selectively lengthened in radial glial progenitor cells undergoing symmetric versus asymmetric division. This lengthening is thought to minimize the potential for copying errors that can occur during DNA replication. Manipulating cell-cycle duration can also affect cell fate, demonstrating that in certain circumstances cell-cycle duration is an instructive process. Currently, cell-cycle length is typically measured using either cumulative labeling with a single thymidine analogue, or via dual thymidine analogue labeling approaches. However, these methods are often time consuming and inefficient. Here, using the embryonic mouse cerebral cortex as a model system, we describe a simplified dual thymidine analogue protocol using BrdU and EdU that can be used to measure Ts and Tc. The advantage of this protocol over cumulative labeling approaches is that only a single time-point is required for measurement. An additional benefit of this protocol over existing dual-analog approaches (CldU/IdU) is the antibody-free detection of EdU and the acid-free detection of BrdU, processes allowing for the parallel use of specific antibodies so as to measure the cell-cycle in immunologically defined cellular subpopulations. PMID- 29445898 TI - Knowledge, Attitudes and Barriers to Human Papillomavirus (HPV) Vaccine Uptake Among an Immigrant and Refugee Catch-Up Group in a Western Canadian Province. AB - Vaccination is a key strategy to prevent cervical cancer in developed countries. Lower uptake of human papillomavirus (HPV) vaccine among new immigrants and refugees has been documented, although exploration of underlying reasons remains an understudied area. Semi-structured interviews with eleven immigrant women (ages 18-26 years) were conducted to understand their knowledge, attitudes and barriers regarding HPV vaccination in a western Canadian province. Participants had limited knowledge about HPV and the vaccine. Most women perceived that their risk of HPV was low, however expressed willingness to receive the vaccine if it were recommended by their physician. Greater efforts are needed to increase knowledge about HPV among immigrant and refugee women and support for physicians to discuss and offer vaccination to this underserved population. PMID- 29445899 TI - Aquarium Trade Supply-Chain Losses of Marine Invertebrates Originating from Papua New Guinea. AB - A major difficulty in managing live organism wildlife trade is often the reliance on trade data to monitor exploitation of wild populations. Harvested organisms that die or are discarded before a point of sale are regularly not reported. For the global marine aquarium trade, identifying supply-chain losses is necessary to more accurately assess exploitation from trade data. We examined quality control rejections and mortality of marine invertebrates (Asteroidea, Gastropoda, Malacostraca, Ophiuroidea) moving through the Papua New Guinea marine aquarium supply-chain, from fisher to importer. Utilizing catch invoices and exporter mortality records we determined that, over a 160 day period, 38.6% of the total invertebrate catch (n = 13,299 individuals) was lost before export. Supply-chain losses were divided among invertebrates rejected in the quality control process (11.5%) and mortality of the accepted catch in transit to, and during holding at, an export facility (30.6%). A further 0.3% died during international transit to importers. We quantified supply-chain losses for the ten most fished species which accounted for 96.4% of the catch. Quality control rejections (n = 1533) were primarily explained by rejections of oversized invertebrates (83.2% of rejections). We suggest that enforceable size limits on species prone to size based rejections and elimination of village-based holding of invertebrates would reduce losses along the Papua New Guinea supply-chain. This case study underscores that low mortality during international transit may mask large losses along supply-chains prior to export and exemplifies the limitations of trade data to accurately monitor exploitation. PMID- 29445900 TI - Clinical interpretation of pathogenic ATM and CHEK2 variants on multigene panel tests: navigating moderate risk. AB - Comprehensive genomic cancer risk assessment (GCRA) helps patients, family members, and providers make informed choices about cancer screening, surgical and chemotherapeutic risk reduction, and genetically targeted cancer therapies. The increasing availability of multigene panel tests for clinical applications allows testing of well-defined high-risk genes, as well as moderate-risk genes, for which the penetrance and spectrum of cancer risk are less well characterized. Moderate-risk genes are defined as genes that, when altered by a pathogenic variant, confer a 2 to fivefold relative risk of cancer. Two such genes included on many comprehensive cancer panels are the DNA repair genes ATM and CHEK2, best known for moderately increased risk of breast cancer development. However, the impact of screening and preventative interventions and spectrum of cancer risk beyond breast cancer associated with ATM and/or CHEK2 variants remain less well characterized. We convened a large, multidisciplinary, cross-sectional panel of GCRA clinicians to review challenging, peer-submitted cases of patients identified with ATM or CHEK2 variants. This paper summarizes the inter professional case discussion and recommendations generated during the session, the level of concordance with respect to recommendations between the academic and community clinician participants for each case, and potential barriers to implementing recommended care in various practice settings. PMID- 29445901 TI - Geology and geochemistry of the Atacama Desert. AB - The Atacama Desert, the driest of its kind on Earth, hosts a number of unique geological and geochemical features that make it unlike any other environment on the planet. Considering its location on the western border of South America, between 17 and 28 degrees S, its climate has been characterized as arid to hyperarid for at least the past 10 million years. Notably dry climatic conditions of the Atacama Desert have been related to uplift of the Andes and are believed to have played an important role in the development of the most distinctive features of this desert, including: (i) nitrates and iodine deposits in the Central Depression, (ii) secondary enrichment in porphyry copper deposits in the Precordillera, (iii) Li enrichment in salt flats of the Altiplano, and (iv) life in extreme habitats. The geology and physiography of the Atacama Desert have been largely shaped by the convergent margin present since the Mesozoic era. The geochemistry of surface materials is related to rock geochemistry (Co, Cr, Fe, Mn, V, and Zn), salt flats, and evaporite compositions in endorheic basins (As, B, and Li), in addition to anthropogenic activities (Cu, Mo, and Pb). The composition of surface water is highly variable, nonetheless in general it presents a circumneutral pH with higher conductivity and total dissolved solids in brines. Major water constituents, with the exception of HCO3-, are generally related to the increase of salinity, and despite the fact that trace elements are not well-documented, surface waters of the Atacama Desert are enriched in As, B, and Li when compared to the average respective concentrations in rivers worldwide. PMID- 29445902 TI - Natural product diversity of actinobacteria in the Atacama Desert. AB - The Atacama Desert of northern Chile is considered one of the most arid and extreme environment on Earth. Its core region was described as featuring "Mars like" soils that were at one point deemed too extreme for life to exist. However, recent investigations confirmed the presence of diverse culturable actinobacteria. In the current review, we discuss a total of 46 natural products isolated to date representing diverse chemical classes characterized from different actinobacteria isolated from various locations in the Atacama Desert. Their reported biological activities are also discussed. PMID- 29445903 TI - Movement Kinematics Dynamically Modulates the Rolandic ~ 20-Hz Rhythm During Goal Directed Executed and Observed Hand Actions. AB - This study investigates whether movement kinematics modulates similarly the rolandic alpha and beta rhythm amplitude during executed and observed goal directed hand movements. It also assesses if this modulation relates to the corticokinematic coherence (CKC), which is the coupling observed between cortical activity and movement kinematics during such motor actions. Magnetoencephalography (MEG) signals were recorded from 11 right-handed healthy subjects while they performed or observed an actor performing the same repetitive hand pinching action. Subjects' and actor's forefinger movements were monitored with an accelerometer. Coherence was computed between acceleration signals and the amplitude of alpha (8-12 Hz) or beta (15-25 Hz) oscillations. The coherence was also evaluated between source-projected MEG signals and their beta amplitude. Coherence was mainly observed between acceleration and the amplitude of beta oscillations at movement frequency within bilateral primary sensorimotor (SM1) cortex with no difference between executed and observed movements. Cross correlation between the amplitude of beta oscillations at the SM1 cortex and movement acceleration was maximal when acceleration was delayed by ~ 100 ms, both during movement execution and observation. Coherence between source-projected MEG signals and their beta amplitude during movement observation and execution was not significantly different from that during rest. This study shows that observing others' actions engages in the viewer's brain similar dynamic modulations of SM1 cortex beta rhythm as during action execution. Results support the view that different neural mechanisms might account for this modulation and CKC. These two kinematic-related phenomena might help humans to understand how observed motor actions are actually performed.

AB - PURPOSE OF REVIEW: At any point in time, there are hundreds of armed conflicts throughout the world. Neuropsychological disorders are a major cause of morbidity during and after armed conflicts. Conditions such as closed and open head injuries, acute stress disorder, post-traumatic stress disorder, depression, anxiety, and psychosis are prevalent among survivors. Herein, we summarize information on the various forms of torture, the resultant neuropsychological pathology, and treatment strategies to help survivors. RECENT FINDINGS: Strategies to address the needs of individuals who experienced neuropsychological trauma due to armed conflicts and torture include pharmacological and psychological interventions. The former includes antidepressant, antianxiety, and antipsychotic medications. The latter includes narrative exposure therapy and trauma-focused cognitive-behavioral therapy. Neuropsychological disorders are major causes of morbidity among survivors of armed conflicts and torture. Treatment strategies must be affordable, applicable across cultures, and deliverable by individuals who understand the victims' psychosocial and ethnic background. PMID- 29445907 TI - Management of Serrated Polyps of the Colon. AB - PURPOSE OF REVIEW: The purpose of this review is to summarize the management of serrated colorectal polyps (SPs), with a particular focus on the most common premalignant SP, sessile serrated adenoma or polyp (SSA/P). These lesions present a challenge for endoscopists with respect to detection and resection, and are also susceptible to pathologic misdiagnosis. RECENT FINDINGS: Patients with SSA/Ps are at an increased risk of future colorectal neoplasia, including advanced polyps and cancer. Reasonable benchmarks for SP detection rates are 5-7% for SSA/Ps and 10-12% for proximal SPs. Certain endoscopic techniques such as chromoendoscopy, narrow band imaging, water immersion, and wide-angle viewing may improve SSA/P detection. Emerging endoscopic techniques such as underwater polypectomy, suction pseudopolyp technique, and piecemeal cold snare polypectomy are helpful tools for the endoscopist's armamentarium for removing SSA/Ps. Proper orientation of SSA/P specimens can improve the accuracy of pathology readings. Patients with confirmed SSA/Ps and proximal HPs should undergo surveillance at intervals similar to what is recommended for patients with conventional adenomas. Patients with SSA/Ps may also be able to lower their risk of future polyps by targeting modifiable risk factors including tobacco and alcohol use and high-fat diets. NSAIDs and aspirin appear to be protective agents. SPs and SSA/Ps in particular are important colorectal cancer precursors that merit special attention to ensure adequate detection, resection, and surveillance. PMID- 29445909 TI - The relationship among preconception depression, anxiety, and social support of the reproductive-aged women in China. AB - The reproductive-aged women have to face physiological and psychological challenges as long as they plan to conceive. However, most previous studies focused on depression and anxiety during pregnancy. This study aimed to investigate the association among preconception depression, anxiety, and social support of the Chinese reproductive-aged women. Nine-hundred five reproductive aged women who planned to conceive for the first or second time in the next three months were recruited through the Maternity and Child Healthcare Hospital and Obstetrics and Gynecology Hospital from three provinces in China. Social Support Rating Scale, Self-Rating Depression Scale, and Self-Rating Anxiety Scale were used in this study. The hierarchical regression model was employed to examine the prediction effect of the three sub-dimensions of social support on preconception depression and anxiety. Of the reproductive-aged women, 25.86 and 13.04% had preconception depression and anxiety symptoms. Nearly all reproductive-aged women had moderate and high social support before pregnancy. The significant differences in depression and anxiety among different levels of occupation and monthly income were found. For depression and anxiety, objective support, support availability, and subjective support simultaneously entered into the model still could significantly explain 5.9 and 6.7% of variations after controlling for the demographic variables, respectively. According to this study, there were significant correlations among preconception depression, anxiety, and social support. And objective support, support availability, and subjective support could negatively predict preconception depression and anxiety. Attaching importance to the preconception mental health and social support can provide effective scientific support for helping women fully understand and effectively use the social resources, and scientifically prepare for pregnancy. PMID- 29445908 TI - Gender Differences in Epidemiology, Pathophysiology, and Treatment of Hypertension. AB - PURPOSE OF REVIEW: This review aims to examine gender differences in both the epidemiology and pathophysiology of hypertension and to explore gender peculiarities on the effects of antihypertensive agents in decreasing BP and CV events. RECENT FINDINGS: Men and women differ in prevalence, awareness, and control rate of hypertension in an age-dependent manner. Studies suggest that sex hormones changes play a pivotal role in the pathophysiology of hypertension in postmenopausal women. Estrogens influence the vascular system inducing vasodilatation, inhibiting vascular remodeling processes, and modulating the renin-angiotensin aldosterone system and the sympathetic system. This leads to a protective effect on arterial stiffness during reproductive age that is dramatically reversed after menopause. Data on the efficacy of antihypertensive therapy between genders are conflicting, and the underrepresentation of aged women in large clinical trials could influence the results. Therefore, further clinical research is needed to uncover potential gender differences in hypertension to promote the development of a gender-oriented approach to antihypertensive treatment. PMID- 29445910 TI - 1H, 13C and 15N resonance assignment of domain 1 of trans-activation response element (TAR) RNA binding protein isoform 1 (TRBP2) and its comparison with that of isoform 2 (TRBP1). AB - TAR RNA binding protein (TRBP) is a double-stranded RNA binding protein involved in various biological processes like cell growth, development, death, etc. The protein exists as two isoforms TRBP2 and TRBP1. TRBP2 contains additional 21 amino acids at its N-terminus, which are proposed to be involved in its membrane localization, when compared to TRBP1. The resonance assignment (19-228) of the double-stranded RNA binding domains (dsRBD 1 and 2) of TRBP2 has been reported earlier. Here, we report 1H, 13C and 15N resonance assignment for dsRBD1 of TRBP2 (1-105) containing the additional N-terminal residues. This assignment will provide deeper insights to understand the effect of these residues on the structure and dynamics of TRBP2 and would therefore help in further elucidating the differences in the role of these isoforms. PMID- 29445911 TI - High prevalence of HCV (GT4)-related TSH abnormality among 13402 Egyptian patients treated with direct acting antiviral therapy. AB - BACKGROUND: HCV is associated with several extra hepatic diseases including thyroid dysfunction. This study aims at evaluating prevalence of thyroid dysfunction and its possible predictors in a large cohort of HCV GT4-infected patients, and the role of thyroid dysfunction as a predictor of response in the setting of direct acting antivirals (DAAs). METHODS: Patients registered on the web-based registry system to receive therapy for chronic HCV in Beheira governorate viral hepatitis specialized treatment center affiliated to the National committee for control of viral hepatitis (NCCVH), Ministry of health, Egypt in the period from January 2015 to October 2016. Their data were exported and analyzed for the prevalence of thyroid dysfunction and its associated variables. RESULTS: Out of 13,402 patients, 2833 (21.1%) had elevated TSH level > 4.5 mIU/l (hypothyroidism). Female gender (62.7%), older age, higher FIB4, AST, and BMI and lower albumin were significantly associated with elevated TSH level on univariate analysis, while liver stiffness measured by fibroscan was not significantly associated. On the other hand, 466 patients (3.5%) showed low TSH level < 0.4 mIU/l (hyperthyroidism). Older age (median 52 years) and male gender (51.5%) were the only significantly associated variables. No association was found between SVR and baseline TSH level. Follow-up of 236 patients after SVR revealed improvement in TSH level in 80% of them. CONCLUSION: Hypothyroidism is prevalent in patients with chronic HCV GT4, and is influenced by patient gender and age. Pretreatment TSH does not affect SVR after DAAs. Despite limited data SVR achievement after DAAs improves thyroid dysfunction.

AB - PURPOSE: Elemental deficiencies are highly prevalent and have a significant impact on health. However, clinical monitoring of plasma elemental responses to foods remains largely unexplored. Data from in vitro studies show that red meat (beef) is a highly bioavailable source of several key elements, but cooking method may influence this bioavailability. We therefore studied the postprandial responses to beef steak, and the effects of two different cooking methods, in healthy young males. METHODS: In a randomized cross-over controlled trial, healthy males (n = 12, 18-25 years) were fed a breakfast of beef steak (270 +/- 20 g) in which the meat was either pan-fried (PF) or sous-vide (SV) cooked. Baseline and postprandial blood samples were collected and the plasma concentrations of 15 elements measured by inductively coupled plasma-mass spectrometry (ICP-MS). RESULTS: Concentrations of Fe and Zn changed after meal ingestion, with plasma Fe increasing (p < 0.001) and plasma Zn decreasing (p < 0.05) in response to both cooking methods. The only potential treatment effect was seen for Zn, where the postprandial area under the curve was lower in response to the SV meal (2965 +/- 357) compared to the PF meal (3190 +/- 310; p < 0.05). CONCLUSIONS: This multi-element approach demonstrated postprandial responsiveness to a steak meal, and an effect of the cooking method used. This suggests the method would provide insight in future elemental metabolic studies to evaluate responses to meat-based meals, including longer-term interventions in more specifically defined cohorts to clearly establish the role of red meat as an important source of elements. PMID- 29445913 TI - Dietary pattern associated with selenoprotein P and MRI-derived body fat volumes, liver signal intensity, and metabolic disorders. AB - PURPOSE: The association of complex dietary patterns with circulating selenoprotein P (SELENOP) levels in humans is unknown. In a general population sample, we aimed to identify a dietary pattern explaining inter-individual variation in circulating SELENOP concentrations and to study this pattern in relation to prevalent diabetes, metabolic syndrome (MetS), MRI-determined total volumes of visceral (VAT) and subcutaneous (SAT) abdominal adipose tissue, and liver signal intensity/fatty liver disease. METHODS: In this cross-sectional study, serum SELENOP levels were measured in 853 individuals. In a subsample of 553 participants, whole-body MRI was performed to assess body fat distribution and liver fat. Dietary intake was assessed by a self-administered food frequency questionnaire and the dietary pattern identified using reduced-rank regression (RRR). Multivariable linear and logistic regressions were used to investigate associations between dietary pattern score and metabolic traits. RESULTS: Characterized by high intake of fruit, vegetables and antioxidant beverages, the RRR-derived dietary pattern displayed inverse associations with VAT, SAT, MetS, and prevalent diabetes in multivariable-adjusted restricted cubic splines. Each unit increase in dietary pattern score was associated with 31% higher SELENOP levels, 12% lower VAT (95% CI: - 19%; - 5%), 13% (95% CI: - 20%; - 6%) lower SAT values and 46% (95% CI: 27%; 60%) and 53% (95% CI: 22%; 72%) lower odds of having MetS or diabetes, respectively. No meaningful relations were observed between the dietary pattern and liver traits. CONCLUSIONS: Our observations propose diet related regulation in SELENOP levels and that the identified dietary pattern is inversely related to VAT, SAT, MetS, and prevalent diabetes. PMID- 29445914 TI - Interaction between dietary acrylamide intake and genetic variants for estrogen receptor-positive breast cancer risk. AB - PURPOSE: The association between dietary acrylamide intake and estrogen receptor positive (ER+) breast cancer risk in epidemiological studies is inconsistent. By analyzing gene-acrylamide interactions for ER+ breast cancer risk, we aimed to clarify the role of acrylamide intake in ER+ breast cancer etiology. METHODS: The prospective Netherlands Cohort Study on diet and cancer includes 62,573 women, aged 55-69 years. At baseline, a random subcohort of 2589 women was sampled from the total cohort for a case-cohort analysis approach. Dietary acrylamide intake of subcohort members (n = 1449) and ER+ breast cancer cases (n = 844) was assessed with a food frequency questionnaire. We genotyped single nucleotide polymorphisms (SNPs) in genes in acrylamide metabolism, sex steroid systems, oxidative stress and DNA repair. Multiplicative interaction between acrylamide intake and SNPs was assessed with Cox proportional hazards analysis, based on 20.3 years of follow-up. RESULTS: Unexpectedly, there was a statistically non significant inverse association between acrylamide and ER+ breast cancer risk among all women but with no clear dose-response relationship, and no association among never smokers. Among the results for 57 SNPs and 2 gene deletions, rs1056827 in CYP1B1, rs2959008 and rs7173655 in CYP11A1, the GSTT1 gene deletion, and rs1052133 in hOGG1 showed a statistically significant interaction with acrylamide intake for ER+ breast cancer risk. CONCLUSIONS: This study did not provide evidence for a positive association between acrylamide intake and ER+ breast cancer risk. If anything, acrylamide was associated with a decreased ER+ breast cancer risk. The interaction with SNPs in CYP1B1 and CYP11A1 suggests that acrylamide may influence ER+ breast cancer risk through sex hormone pathways.

PMID- 29445916 TI - Bottom-of-sulcus focal cortical dysplasia presenting as epilepsia partialis continua multimodality characterization including 7T MRI. AB - INTRODUCTION: Bottom-of-sulcus focal cortical dysplasias are an under recognized, surgically treatable cause of focal epilepsy. Resection can dramatically reduce the seizure burden for children with refractory epilepsy, or eliminate seizures altogether. MATERIAL AND METHODS: We report the case and present the results of multimodality evaluation of a 15-year-old young man who presented with long standing partial epilepsy affecting his right leg, which over the years became refractory to therapy. RESULTS: High-resolution 3T MRI images acquired as a dedicated epilepsyprotocol were initially interpreted as unremarkable. On further review by an experienced specialist aware of clinical and electroencephalographic findings, a subtle focal cortical dysplasia was identified at the bottom of a sulcus near the medial aspect of the left precentral gyrus. After confirmation of the extent of the lesion with PET and ultra-high field 7T MRI, the patient underwent cortical mapping and focal resection and remains free of seizures. COCLUSIONS: This case emphasizes the need for a multidisciplinary approach to the evaluation of refractory focal epilepsy in children and highlights the potential role of ultra-high field 7T MRI in identifying the often subtle causative anatomic abnormalities.

PMID- 29445918 TI - Persistent craniopharyngeal canal, bilateral microphthalmia with colobomatous cysts, ectopic adenohypophysis with Rathke cleft cyst, and ectopic neurohypophysis: case report and review of the literature. AB - INTRODUCTION: Persistent craniopharyngeal canal (PCC) is a rare anomaly of the base of the skull. PCC is defined as a well-corticated osseous canal, extending from the roof of the nasopharynx to the base of the sella over the course of the sphenoid corpus. We reported a PCC case with unique associations. The magnetic resonance imaging findings are discussed. CASE PRESENTATION: We report a case of a 2-year-old boy with persistent craniopharyngeal canal, bilateral microphtalmia with large colobomatous cyst, and ectopic adenohypophysis with Rathke cleft cyst. He also has ectopic neurohypophysis and optic atrophy. CONCLUSION: The presence of orbital and optic tract malformations, craniofacial and intracranial anomalies, and tumors can accompany craniopharyngeal canals (CCs). MRI is helpful in the evaluation of PCC and associated anomalies in these patients. PMID- 29445919 TI - Appraisal of clinical practice guidelines on the management of hypothyroidism in pregnancy using the Appraisal of Guidelines for Research and Evaluation II instrument. AB - PURPOSE: This study aimed to systematically evaluate the quality of guidelines for the management of hypothyroidism in pregnancy. METHOD: Systematic searches were conducted to identify hypothyroidism in pregnancy guidelines published in electronic databases and developers' websites. Four reviewers independently evaluated eligible guidelines using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument. Agreement among reviewers was measured using the intraclass correlation coefficient (ICC). The number of recommendations, strength of recommendations, and levels of evidence were determined. The software used for analysis was SPSS version 12.0. RESULTS: Nine guidelines met the inclusion criteria and were appraised. The scope and purpose (65%) and clarity of presentation (70%) domains achieved relatively high scores, whereas the stakeholder involvement (41%), rigor of development (33%), applicability (36%), and editorial independence (31%) domains yielded low scores. The American Thyroid Association (ATA) guideline ranked the highest, whereas the 2012 Chinese Society of Endocrinology (CSE) guideline ranked the lowest among all the guidelines. The British Thyroid Association (BTA) and ATA guidelines were strongly recommended as dependable and helpful references to aid clinical decisions for medical providers, whereas the CSE guideline was not recommended. Most recommendations of the guidelines were relatively consistent. However, the nine guidelines varied with respect to their recommendations on thyroid scanning, dose of levothyroxine (L-T4) treatment, and target thyroid-stimulating hormone(TSH) level of L-T4 therapy. CONCLUSIONS: The quality of the guidelines on the management of hypothyroidism in pregnancy is highly variable. Additionally, these guidelines need significant improvement, especially in the rigor of development and applicability domains. Some improvements should be made to promote the development and implementation of guidelines, for example, conducting a comprehensive search strategy to include more potential evidence and establishing a standard grading system to evaluate the quality of evidence. PMID- 29445921 TI - Spontaneous Regression and Resolution of Breast Implant-Associated Anaplastic Large Cell Lymphoma: Implications for Research, Diagnosis and Clinical Management. AB - BACKGROUND: First described in 1997, breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) was recognised by the World Health Organisation in 2016 as a specific disease. It typically presents as a late seroma-containing atypical, monoclonal T cells which are CD30+ and anaplastic lymphoma kinase negative. Until recently, it was thought that the disease was very rare. However, it is being diagnosed increasingly frequently with 56 cases confirmed in Australia by September 2017 and the estimated incidence revised from 1 in 300,000 to between 1 in 1000 and 1 in 10,000 patients with bilateral implants. There is debate about the spectrum of BIA-ALCL. According to the current WHO classification, BIA-ALCL is a cancer in all cases. Treatment guidelines require that it is treated urgently with a minimum of bilateral removal of implants and capsulectomies. Whilst acknowledging the disease has been under diagnosed in the past, with some notable exceptions the BIA-ALCL literature has given scant attention to the epidemiological evidence. Now that it is known that the disease may occur in up to 1 in 1000 patients with a median of 7.5 years from implantation to diagnosis, understanding it in its epidemiological context is imperative. The epidemiology of cancer and lymphoma in women with breast implants strongly suggests that most patients do not have a cancer that will inevitably progress without treatment but instead a self-limiting lympho-proliferative disorder. Although the possibility of spontaneous regression has been raised and the observation made that treatment delay did not seem to increase the risk of spread, the main objection to the lympho-proliferative hypothesis has been the lack of documented cases of spontaneous regression or resolution. Because all cases currently are considered malignant and treated urgently, only case report evidence, interpreted in the proper epidemiological context, is likely to be available to challenge this thinking. METHODS AND RESULTS: New observations and interpretation of the epidemiology of BIA-ALCL are made. These are supported by the presentation of two cases, which to the best of our knowledge comprise the first documented evidence of spontaneous regression and spontaneous resolution of confirmed BIA-ALCL. CONCLUSIONS: The epidemiology of the disease strongly suggests that the vast majority of cases are not a cancer that will inevitably progress without treatment. The findings presented in the manuscript provide supportive clinical evidence. Consequently, an alternative view of BIA-ALCL with implications for research, diagnosis and clinical management needs to be considered.

PMID- 29445920 TI - Phylogenetic Diversity and In Vitro Susceptibility Profiles of Human Pathogenic Members of the Fusarium fujikuroi Species Complex Isolated from South India. AB - Availability of molecular methods, gene sequencing, and phylogenetic species recognition have led to rare fungi being recognized as opportunistic pathogens. Fungal keratitis and onychomycosis are fairly common mycoses in the tropics, especially among outdoor workers and enthusiasts. The frequently isolated etiological agents belong to genera Candida, Aspergillus, and Fusarium. Within the genus Fusarium, known to be recalcitrant to prolonged antifungal treatment and associated with poor outcome, members of the Fusarium solani species complex are reported to be most common, followed by members of the Fusarium oxysporum SC and the Fusarium fujikuroi SC (FFSC). Morphological differentiation among the various members is ineffective most times. In the present study, we describe different species of the FFSC isolated from clinical specimen in south India. All twelve isolates were characterized up to species level by nucleic acid sequencing and phylogenetic analysis. The molecular targets chosen were partial regions of the internal transcribed spacer rDNA region, the panfungal marker and translation elongation factor-1alpha gene, the marker of choice for Fusarium speciation. Phylogenetic analysis was executed using the Molecular Evolutionary Genetics Analysis software (MEGA7). In vitro susceptibility testing against amphotericin B, voriconazole, posaconazole, natamycin, and caspofungin diacetate was performed following the CLSI M38-A2 guidelines for broth microdilution method. The twelve isolates of the FFSC were F. verticillioides (n = 4), F. sacchari (n = 3), F. proliferatum (n = 2), F. thapsinum (n = 1), F. andiyazi (n = 1), and F. pseudocircinatum (n = 1). To the best of our knowledge, this is the first report of F. andiyazi from India and of F. pseudocircinatum as a human pathogen worldwide. Natamycin and voriconazole were found to be most active agents followed by amphotericin B. Elderly outdoor workers figured more among the patients and must be recommended protective eye wear. PMID- 29445922 TI - Education on the Business of Plastic Surgery During Training: A Survey of Plastic Surgery Residents. AB - BACKGROUND: Entrepreneurial skills are important for physicians, especially plastic surgeons. Nevertheless, these skills are not typically emphasized during residency training. OBJECTIVE: Evaluate the extent of business training at plastic surgery residency programs as well as means of enhancing business training. METHODS: A 6-question online survey was sent to plastic surgery program directors for distribution to plastic surgery residents. Responses from residents at the PGY2 level and above were included for analysis. Tables were prepared to present survey results. RESULTS: Hundred and sixty-six residents including 147 PGY2 and above residents responded to our survey. Only 43.5% reported inclusion of business training in their plastic surgery residency. A majority of residents reported they do not expect on graduation to be prepared for the business aspects of plastic surgery. Additionally, a majority of residents feel establishment of a formal lecture series on the business of plastic surgery would be beneficial. CONCLUSIONS: Results from our survey indicate limited training at plastic surgery programs in necessary business skills. Plastic surgery residency programs should consider incorporating or enhancing elements of business training in their curriculum.

PMID- 29445923 TI - Inpatient outcomes of preterm infants receiving omega-3 enriched lipid emulsion (SMOFlipid): an observational study. AB - : Neonatal units have started to switch from using conventional soy-based to alternate lipid emulsions, like SMOFlipid. SMOFlipid has been associated with an improvement in biochemical parameters and delays progression of parenteral nutrition-associated liver disease (PNALD). This retrospective epoch study aimed to compare clinically relevant neonatal outcomes in preterm infants (< 32 weeks), receiving SMOFlipid versus Intralipid. We compared clinical outcomes in two epochs-epoch 1 (Intralipid, October 2013-June 2015) versus epoch 2 (SMOFlipid, July 2015-March 2017). Primary outcome studied was mortality and rates of severe neonatal morbidities. Univariate and multivariate regression was conducted to determine risk for mortality and PNALD. A total of 222 infants (epoch 1, 123 versus epoch 2, 99) were included in the study. A higher incidence of late onset sepsis (56 versus 30%, p < 0.005) was observed in epoch 1. There was no significant difference in mortality or rates of any other severe neonatal morbidity. The type of lipid emulsion did not have a significant effect on mortality or PNALD on regression analysis. CONCLUSION: Use of SMOFlipid as the primary lipid emulsion seems to have minimal effect on rates of clinically important neonatal outcomes; however, long-term effects need to be further evaluated. What is Known: * Many neonatal units have started replacing traditional soy-based lipid formulations with SMOFlipid (omega-3 enriched lipid emulsion), as the primary lipid component in parenteral nutrition for preterm infants. * While there is evidence associating improved liver function and balanced essential fatty acid levels in infants receiving SMOFlipid, there is a lack of evidence evaluating relevant clinical outcomes in infants receiving SMOFlipid versus traditional lipid formulations. What is New: * The influence of SMOFlipid on a series of clinical outcomes in an at-risk preterm population is presented. * SMOFlipid appears to be well tolerated in preterm infants with minimal side effects, and some growth benefits seen. PMID- 29445925 TI - Tubal restorative surgery for hydrosalpinges in women due to in vitro fertilization. AB - OBJECTIVE: The study was carried out to clarify the IVF outcome after laparoscopic neosalpingostomy for infertile patients affected by hydrosalpinx stage III. MATERIALS AND METHODS: From January 2010 to June 2015, 91 subjects of hydrosalpinx stage III were treated in out center by laparoscopic surgery before IVF cycle. 43 underwent neosalpingostomy (group 1) and the remaining 48 underwent salpingestomy (group 2). We compared these patients and their IVF outcomes after two different surgical techniques. RESULTS: There were no significant differences between the two groups, except a higher number of patients with bilaterial hydrosalpinges was noted in the neosalpingostomy group (79.1% vs. 56.3%, respectively). 25 patients with neosalpingostomy and 29 with salpingectomy achieved pregnancy by IVF. The ongoing pregnancy rate per cycle in group 1 and group 2 was 51.1 and 47.2%, respectively. Two cases of ampullary ectopic pregnancies were noted in group 1 and one case of right tube interstitial pregnancy in group 2. No significant difference was observed in live birth rate between the groups (48.9% vs. 45.3%, respectively). CONCLUSIONS: The outcomes of IVF after neosalpingostomy were matchable with salpingectomy. For patients desire to preserve fallopian tubes, we recommend laparoscopic neosalpingostomy as an alternative choice to manage moderate hydrosalpinx before IVF.

PMID- 29445926 TI - Single versus double-balloon catheters for the induction of labor of singleton pregnancies: a meta-analysis of randomized and quasi-randomized controlled trials. AB - OBJECTIVE: To compare the efficacy of single- versus double-balloon catheter (SBC vs. DBC) for cervical ripening and labor induction with an unfavorable cervix. METHODS: Systematic review and meta-analysis of randomized controlled trials (RCTs) or quasi-RCTs (qRCT) regarding the use of SBC or DBC for labor induction of live singleton cephalic pregnancies (>= 35 weeks) of any parity with an unripe cervix (Bishop score <= 6). Nine research databases were searched for original articles published in all languages up to November 2017 comparing both devices for labor induction. Five RCTs and one qRCT were included. Primary outcome measures were time from intervention (device placement) to birth time, vaginal delivery and cesarean section rates, and maternal satisfaction with the procedure. Risk of bias was evaluated with the Cochrane tool. Random effects models were used to combine data for meta-analyses. Summary measures were reported as mean differences and risk ratios (RR) with 95% confidence intervals. RESULTS: Regardless of parity, pooled analyses of the six trials (n = 1060 women) found that mean intervention to birth time, vaginal delivery and cesarean section rates, and maternal satisfaction to the procedure were similar for both studied groups (SBC vs. DBC). CONCLUSION: Measured primary outcome measures were similar regardless of the type of device used for labor induction of singleton pregnancies. PMID- 29445928 TI - Efficacy and safety of trastuzumab, lapatinib, and paclitaxel neoadjuvant treatment with or without prolonged exposure to anti-HER2 therapy, and with or without hormone therapy for HER2-positive primary breast cancer: a randomised, five-arm, multicentre, open-label phase II trial. AB - BACKGROUND: Dual blockade of HER2 promises increased pathological complete response (pCR) rate compared with single blockade in the presence of chemotherapy for HER2-positive (+) primary breast cancer. Many questions remain regarding optimal duration of treatment and combination impact of endocrine therapy for luminal HER2 disease. METHODS: We designed a randomised phase II, five-arm study to evaluate the efficacy and safety of lapatinib and trastuzumab (6 weeks) followed by lapatinib and trastuzumab plus weekly paclitaxel (12 weeks) with/without prolongation of anti-HER2 therapy prior to chemotherapy (18 vs. 6 weeks), and with/without endocrine therapy in patients with HER2+ and/or oestrogen receptor (ER)+ disease. The primary endpoint was comprehensive pCR (CpCR) rate. Among the secondary endpoints, pCR (yT0-isyN0) rate, safety, and clinical response were evaluated. RESULTS: In total, 215 patients were enrolled; 212 were included in the full analysis set (median age 53.0 years; tumour size = T2, 65%; and tumour spread = N0, 55%). CpCR was achieved in 101 (47.9%) patients and was significantly higher in ER- patients than in ER+ patients (ER- 63.0%, ER+ 36.1%; P = 0.0034). pCR with pN0 was achieved in 42.2% of patients (ER- 57.6%, ER+ 30.3%). No significant difference was observed in pCR rate between prolonged exposure groups and standard groups. Better clinical response outcomes were obtained in the prolongation phase of the anti-HER2 therapy. No surplus was detected in pCR rate by adding endocrine treatment. No major safety concern was recognised by prolonging the anti-HER2 treatment or adding endocrine therapy. CONCLUSIONS: This study confirmed the therapeutic impact of lapatinib, trastuzumab, and paclitaxel therapy for each ER- and ER+ subgroup of HER2+ patients. Development of further strategies and tools is required, particularly for luminal HER2 disease. PMID- 29445929 TI - Prevalence of Leptospira serogroup-specific antibodies in cattle associated with reproductive problems in endemic states of India. AB - In this study, the seroprevalence and distribution of Leptospira in dairy cattle in endemic states of India were investigated in association with reproductive problems of the cattle. A total of 373 cattle serum samples from 45 farms in Maharashtra, Gujarat, Andhra Pradesh, Telangana, Karnataka, Tamil Nadu, Punjab, Haryana, Chhattisgarh, Sikkim and Uttarakhand states were collected from animals with a history of reproductive disorders like abortion, repeat breeding, anoestrus and endometritis, and also from apparently healthy animals. These samples were screened for Leptospira serogroup-specific antibodies by microscopic agglutination test (MAT) using a panel of 18 live reference serovar antigens. The seropositivity of 70.51% (263/373, 95% CI 0.65 to 0.75) was associated with reproductive problems (chi2 = 55.71, p < 0.01) and sampled states (chi2 = 32.99, p < 0.01) and independent of apparently healthy animals (chi2 = 15.6, p > 0.10) and age groups of cattle (chi2 = 0.91, p > 0.10). Further, the odds (risk relation) of reproductive disorders was 5.29 compared to apparently healthy animals (0.25 odds). The frequency distribution of predominant serogroup-specific Leptospira antibodies were determined against the serovars: Hardjo (27.76%), Pyrogenes (18.63%), Canicola and Javanica (17.49%), Hebdomadis (17.11%), Shermani and Panama (16.73%), Djasiman (16.35%), Tarassovi, Grippotyphosa and Pomona (15.97%), Icterohaemorrhagiae (15.59%), Copenhageni (14.83%), Australis (13.69%), Kaup and Hurstbridge (10.65%), Bankinang (10.27%) and Bataviae (9.51%). In conclusion, dairy cattle have a role in maintaining important several serovars besides well-known Hardjo serovar in endemic states of India and warrant mitigating measures to reduce the incidence of cattle leptospirosis including need for an intensive surveillance programme, preventive vaccination and control strategies. PMID- 29445931 TI - A rare case of pelvic bone duplication. AB - Iliac bone malformations are rare and result from early disturbance of the genetic and epigenetic processes that come together to form the pelvic girdle.

PMID- 29445930 TI - ZBTB17 loss-of-function mutation contributes to familial dilated cardiomyopathy. AB - Dilated cardiomyopathy (DCM) is a common primary myocardial disease leading to congestive heart failure, arrhythmia and sudden cardiac death. Increasing studies demonstrate substantial genetic determinants for DCM. Nevertheless, DCM is of substantial genetic heterogeneity, and the genetic basis for DCM in most patients remains unclear. The present study was sought to investigate the association of a genetic variant in the ZBTB17 gene with DCM. A cohort of 158 unrelated patients with idiopathic DCM and a total of 230 unrelated, ethnically matched healthy individuals used as controls were recruited. The coding exons and splicing boundaries of ZBTB17 were sequenced in all study participants. The functional effect of the mutant ZBTB17 was characterized by a dual-luciferase reporter assay system. A novel heterozygous ZBTB17 mutation, p.E243X, was discovered in an index patient. Genetic scan of the mutation carrier's available relatives showed that the mutation was present in all affected family members but absent in unaffected family members. Analysis of the proband's pedigree revealed that the mutation co segregated with DCM, which was transmitted in an autosomal dominant pattern with complete penetrance. The nonsense mutation was absent in the 460 control chromosomes. Functional assays demonstrated that the truncated ZBTB17 protein had no transcriptional activity as compared with its wild-type counterpart. This study firstly associates ZBTB17 loss-of-function mutation with enhanced susceptibility to DCM in humans, which provides novel insight into the molecular mechanism underpinning DCM, implying potential implications for genetic counseling and personalized management of DCM. PMID- 29445932 TI - Fibrodysplasia ossificans progressiva: a current review of imaging findings. AB - OBJECTIVE: Fibrodysplasia ossificans progressiva is a rare genetic disorder characterized by congenital skeletal deformities and soft tissue masses that progress to heterotopic ossification. Deformities of the great toes are distinctive, and heterotopic ossification in the soft tissues follows an expected anatomic and temporal pattern. In addition to heterotopic ossification, osteochondromata, middle ear ossification, demyelination, lymphedema, and venous thrombosis are characteristic. Awareness of this constellation of findings is important to early diagnosis and surveillance. CONCLUSIONS: Recognition of the imaging manifestations of fibrodysplasia ossificans progressiva is imperative to early diagnosis in order to appropriately direct patient care and preclude unnecessary biopsies or surgical procedures. PMID- 29445933 TI - Multimodality imaging of subacromial impingement syndrome. AB - Subacromial impingement syndrome results from irritation of the tendons of the rotator cuff muscles in the subacromial space and may manifest as a range of pathologies. However, subacromial impingement is a dynamic condition for which imaging reveals predisposing factors but no pathognomonic indicators. Also, the usual imaging features of subacromial impingement may be seen in symptomatic and asymptomatic patients. Therefore, imaging is able to detect tears and describe the risk factors of impingement but cannot confirm subacromial impingement. Radiographs allow assessment of the morphology of the acromion and its lateral extension by means of the acromial index and the critical shoulder angle, which may increase in cases of subacromial impingement. Ultrasound is necessary to evaluate a tendon tear and is the only tool that provides dynamic information, which is essential to assessing dynamic conditions. Magnetic resonance imaging (MRI) allows the assessment of associated intraarticular abnormalities, joint effusion, and bone marrow edema. The objective of this article is to provide an overview of the pathophysiology and clinical manifestations of subacromial impingement and discuss recent advances in the imaging of subacromial impingement and the role of radiography, ultrasound, and MRI in differentiating normal from pathologic findings. PMID- 29445934 TI - Serum Surfactant Protein Levels in Patients Admitted to the Hospital with Acute COPD Exacerbation. AB - Surfactant proteins (SPs) have been studied in COPD patients as biomarkers of disease severity and as predictive factors of unfavorable outcomes. The aim of this exploratory study was to evaluate serum levels of SP-A, SP-B, SP-C, and SP-D in patients with COPD both during AECOPD and in stability and to test their possible associations with disease severity and with the development of new exacerbation events. 20 consecutive COPD patients hospitalized for AECOPD were included. Serum SP levels were measured on admission, at discharge, and on stability. SP-A levels were significantly lower both on admission and at discharge in patients with early relapse compared to those with late or no relapse (29.2 +/- 9.1 vs. 43.9 +/- 16.9 ng/ml, p = 0.037, and 24.3 +/- 2.8 vs. 39.3 +/- 14.2 ng/ml, p = 0.011, respectively). SP-B levels were found to have a trend to be higher at discharge and significantly higher on stability in patients experiencing an early relapse compared to those with late or no relapse (52.5 +/- 31.6 vs. 31.4 +/- 32.3 ng/ml, p = 0.052 and 64.8 +/- 32.6 vs. 32.8 +/- 25.6 ng/ml, p = 0.024, respectively). Finally, the ROC analysis showed that serum SP A, SP-B, and SP-C levels at discharge, seemed to be significant predictors of early relapse. Our conclusion is that serum levels of SPs might be related to disease outcomes in COPD patients. PMID- 29445935 TI - Readmission Due to Exacerbation of COPD: Associated Factors. AB - OBJECTIVES: To compare characteristics of patients readmitted after discharge by chronic obstructive pulmonary disease (COPD) exacerbation with those who were not readmitted and to identify factors associated with readmission risk. PATIENTS AND METHODS: We randomly selected a group of 40 COPD patients with high frequency of readmissions (HFR), who had >= 2 admissions by COPD exacerbation within 30 days after the last admission in 2015, and another group of 40 COPD patients with low frequency of readmissions (LFR), with 0-1 admissions in that period. RESULTS: Patients of the HFR group, compared to those in LFR group, were more frequently males (p = 0.009), older (p = 0.022), had a higher degree of dyspnea (p = 0.044), worse lung function (p = 0.049), belonged more frequently to exacerbator emphysema phenotype (p < 0.001), and had a higher frequency of diabetes (p = 0.049). The variables independently associated with increased risk of HFR were sex (OR 0.06, 95% CI 0.01-0.63, in women in relation to males), exacerbator emphysema phenotype (OR 28.61, 95% CI 3.59 compared to non-exacerbator phenotype), complications during hospitalization (OR 0.09, 95% CI 0.01-0.62, compared with those without complications), destabilized heart failure (OR 5.25, 95% CI 1.11-24.75, compared to those who did not), and length of hospital stay (OR 0.79, 95% CI 0.65-0.95, per day). CONCLUSIONS: Chronic obstructive pulmonary disease patients with HFR are more frequently male, older, have worse dyspnea, lower lung function, belong more frequent to exacerbator emphysema phenotype, and more frequently diabetics. The variables that continued to be independent predictors of HFR in the multivariate analysis were sex, phenotype, occurrence of complications during admission, destabilized heart failure, and length of hospital stay.

AB - OBJECTIVES: Systemic sclerosis (SSc) is a chronic, inflammatory, and autoimmune connective tissue disease that is associated with vascular lesions, and fibrosis of the skin and visceral organs. Cardiac complications may occur as a secondary effect of SSc as a result of pulmonary arterial hypertension and interstitial lung disease. The objective of this study was to assess whether the pulmonary pulse transit time (pPTT) could serve as a diagnostic marker for pulmonary arterial alterations in patients with SSc, prior to development of pulmonary hypertension. METHODS: Twenty-five SSc patients as a study group and 25 age- and sex-matched healthy volunteers for the control group were recruited to the study. Right ventricle function parameters, such as tricuspid annular plane systolic excursion (TAPSE), estimated pulmonary artery systolic pressure (ePASP), right ventricular dimensions, right ventricle fractional area changes, and myocardial perfusion index (MPI) were measured and calculated. Pulmonary pulse transit time was defined as the time interval between the R-wave peak in the ECG and the corresponding peak late systolic pulmonary vein flow velocity. RESULTS: Right ventricle myocardial performance index (RVMPI) and eSPAP were significantly higher in the SSc group than the controls (p = 0.032, p = 0.012, respectively). Pulmonary pulse transit time and TAPSE was shorter in the patients with SSc (p = 0.006, p = 0.015, respectively). In correlation analysis, pPTT was inversely correlated with RVMPI (r = - 0.435, p = 0.003), eSPAP (r = - 0.434, p = 0.003), and disease duration (r = - 0.595, p = 0.003). Conversely, it positively correlated with TAPSE (r = 0.345, p = 0.022). CONCLUSION: pPTT was found to be shorter in SSc patients. pPTT might serve as a surrogate marker of pulmonary hemodynamics in patients with SSc, even prior to the development of pulmonary hypertension. PMID- 29445937 TI - Secondary Hemophagocytic Syndrome Associated with COG6 Gene Defect: Report and Review. AB - Hemophagocytic lymphohistiocytosis (HLH) is a rare but potentially fatal disease that is characterized by proliferation and infiltration of hyperactivated macrophages and T-lymphocytes. Clinically, it is characterized by prolonged fever, hepatosplenomegaly, hypertriglyceridemia, hypofibrinogenemia, pancytopenia, and hemophagocytosis in the bone marrow, spleen, or lymph nodes. It can be classified as primary if it is due to a genetic defect, or secondary if it is due to a different etiology such as severe infection, immune deficiency syndrome, rheumatological disorder, malignancy, and inborn errors of metabolism such as galactosemia, multiple sulfatase deficiency, lysinuric protein intolerance, Gaucher disease, Niemann-Pick disease, Wolman disease, propionic acidemia, methylmalonic acidemia, biotinidase deficiency, cobalamin C defect, galactosialidosis, Pearson syndrome, and long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD) deficiency. For the first time in the literature, we report on a 5-year-old girl diagnosed with a Component of Oligomeric Golgi Complex 6 (COG6) gene defect complicated by HLH. Finally, we review the literature on inborn errors of metabolism associated with HLH and compare the previously reported patients of COG6 gene defect with our patient. PMID- 29445938 TI - Mental Health of Homeless Youth: Moderation by Peer Victimization and Teacher Support. AB - The link between youth homelessness and mental health functioning was examined using state population-representative 2015 Youth Risk Behavior Survey (YRBS) data. The moderating role of victimization and perceived teacher support also was examined. Consistent with hypotheses, results indicated that homelessness was associated with greater mental health challenges, more victimization, and less teacher support. The association between homelessness and mental health was not moderated by perceived teacher support. However, victimization experiences served as a moderator such that more victimization exacerbated the effect of homelessness on mental health challenges. This study supports the utility of the YRBS for gaining understanding of the experiences and needs of youth experiencing homelessness and adds to the growing literature on predictors of individual differences in mental health functioning of these vulnerable youth. PMID- 29445939 TI - A comparison of two models for breast cancer mortality for women with ductal carcinoma in situ: an SEER-based analysis. AB - BACKGROUND: Approximately 1% of patients with ductal carcinoma in situ (DCIS) will die of breast cancer within 10 years. Women who develop an invasive breast cancer after DCIS have a much greater risk of dying than those who do not and it is often stated that these deaths are a consequence of metastases from the invasive in-breast recurrence. This progression is the result of a two-step process: first local invasive recurrence and then spread beyond the breast. A large proportion of women who die of DCIS have no record of invasive recurrence. We used SEER data and a simulation approach to test whether the actual mortality data are consistent with the two-step model. METHODS: First, we constructed Kaplan-Meier mortality curves for all patients with pure DCIS and with small node negative invasive breast cancers in the Surveillance, Epidemiology and End Results (SEER) registries database (1998-2014). We then constructed, through simulation, theoretical breast cancer mortality curves. To model the two-step scenario, we applied the annual incidence rates of incident invasive cancer following DCIS and of death from invasive cancer after DCIS to a theoretical cohort of 100,000 women. RESULTS: The observed 15-year breast cancer-specific mortality rate for patients with pure DCIS in the SEER database was 2.0%. The expected mortality for DCIS patients (assuming a two-step process) was only 1.1% at 15 years. Assuming the mortality rates following DCIS were one-half of those observed for patients with small invasive breast cancers, the expected mortality at 15 years post-DCIS was 2.1%. CONCLUSIONS: In the SEER database, we observed far more deaths from DCIS than would be expected under a model where all deaths from breast cancer occur amongst women who experience an invasive local recurrence. This lends support to the hypothesis that DCIS mortality is not restricted to those women who experience an in-breast invasive cancer and that DCIS has properties similar to small invasive breast cancers. PMID- 29445941 TI - Population norms for the EQ-5D-3L: a cross-country analysis of population surveys for 20 countries. AB - This study provides EQ-5D population norms for 20 countries (N = 163,838), which can be used to compare profiles for patients with specific conditions with data for the average person in the general population in a similar age and/or gender group. Descriptive EQ-5D data are provided for the total population, by gender and by seven age groups. Provided index values are based on European VAS for all countries, based on TTO for 11 countries and based on VAS for 10 countries. Important differences exist in EQ-5D reported health status across countries after standardizing for population structure. Self-reported health according to all five dimensions and EQ VAS generally decreased with increasing age and was lower for females. Mean self-rated EQ VAS scores varied from 70.4 to 83.3 in the total population by country. The prior living standards (GDP per capita) in the countries studied are correlated most with the EQ VAS scores (0.58), while unemployment appeared to be significantly correlated in people over the age of 45 only. A country's expenditure on health care correlated moderately with higher ratings on the EQ VAS (0.55). EQ-5D norms can be used as reference data to assess the burden of disease of patients with specific conditions. Such information, in turn, can inform policy-making and assist in setting priorities in health care. PMID- 29445940 TI - Differences in breast cancer incidence among young women aged 20-49 years by stage and tumor characteristics, age, race, and ethnicity, 2004-2013. AB - PURPOSE: Younger women diagnosed with breast cancer have poorer prognoses and higher mortality compared to older women. Young black women have higher incidence rates of breast cancer and more aggressive subtypes than women of other races/ethnicities. In this study, we examined recent trends and variations in breast cancer incidence among young women in the United States. METHODS: Using 2004-2013 National Program of Cancer Registries and Surveillance, Epidemiology, and End Results Program data, we calculated breast cancer incidence rates and trends and examined variations in stage, grade, and tumor subtype by age and race/ethnicity among young women aged 20-49 years. RESULTS: The majority of breast cancer cases occurred in women aged 40-44 and 45-49 years (77.3%). Among women aged < 45 years, breast cancer incidence was highest among black women. Incidence trends increased from 2004 to 2013 for Asian or Pacific Islander (API) women and white women aged 20-34 years. Black, American Indian or Alaska Native, and Hispanic women had higher proportions of cases diagnosed at later stages than white and API women. Black women had a higher proportion of grade III-IV tumors than other racial/ethnic groups. Across all age groups, incidence rates for triple-negative breast cancer were significantly higher in black women than women of other races/ethnicities, and this disparity increased with age. CONCLUSIONS: Breast cancer among young women is a highly heterogeneous disease. Differences in tumor characteristics by age and race/ethnicity suggest opportunities for further research into personal and cultural factors that may influence breast cancer risk among younger women. PMID- 29445942 TI - Market structure and competition in the healthcare industry : Results from a transition economy. AB - The present paper provides first empirical evidence on the relationship between market size and the number of firms in the healthcare industry for a transition economy. We estimate market-size thresholds required to support different numbers of suppliers (firms) for three occupations in the healthcare industry in a large number of distinct geographic markets in Slovakia, taking into account the spatial interaction between local markets. The empirical analysis is carried out for three time periods (1995, 2001 and 2010) which characterise different stages of the transition process. Our results suggest that the relationship between market size and the number of firms differs both across industries and across periods. In particular, we find that pharmacies, as the only completely liberalised market in our dataset, experience the largest change in competitive behaviour during the transition process. Furthermore, we find evidence for correlation in entry decisions across administrative borders, suggesting that future market analysis should aim to capture these regional effects. PMID- 29445944 TI - Diagnosis and treatment of anti-myelin oligodendrocyte glycoprotein antibody positive optic neuritis. AB - Anti-myelin-oligodendrocyte glycoprotein (MOG) antibody positive optic neuritis has been established as a new subset of optic neuropathy. Anti-MOG antibodies are usually measured by cell-based assay. Patients with anti-MOG antibody positive optic neuritis respond well to steroid therapy, and, while visual acuity outcomes are favorable, significant visual field defects remain. Furthermore, patients who are anti-MOG antibody positive have higher rates of recurrence compared to antibody negative patients. Based on these findings, anti-MOG antibody positive patients with optic neuritis have the characteristics of good visual outcomes, residual visual field defects, and high risk of recurrence. Tests for anti-MOG antibody are useful for the diagnosis and treatment of optic neuritis. PMID- 29445943 TI - Impact of the clinical use of ROCK inhibitor on the pathogenesis and treatment of glaucoma. AB - Rho-associated protein kinase (ROCK), a ubiquitously expressed signaling messenger and downstream effector of Rho, is activated by several bioactive factors in the aqueous humor (AH). Rho-ROCK signaling regulates a wide spectrum of fundamental cellular events, including cell adhesion, motility, proliferation, differentiation, and apoptosis. Previous studies, including our own, found that ROCK inhibitor lowers intraocular pressure (IOP) via a direct effect on the conventional AH outflow pathway, by regulation of contractile properties, fibrotic activity, and permeability of the trabecular meshwork (TM) and Schlemm's canal (SC) tissues, influencing extracellular matrix (ECM) production. Recently, a novel ROCK inhibitor, ripasudil, has been introduced in Japan. Other ROCK inhibitors are now in clinical trials as new IOP-lowering drugs for glaucoma patients. To date, ripasudil, administered together with other glaucoma medications, has proved safe and efficient in lowering IOP as well as additional effects such as prostaglandin analogs, beta-blockers, and carbonic anhydrase inhibitors, all of which help lower IOP by different mechanisms. In addition, we found that long-term treatment with ripasudil exerted an additional IOP-lowering effect, especially in eyes with high IOP, suggesting that late-onset remodeling of the ECM in glaucomatous eyes may elicit mild and delayed changes in IOP levels. ROCK inhibitors have also shown several additional effects, including increased retinal blood flow, direct protection of neurons against various types of stress, and regulation of wound healing; these benefits may potentially be useful in glaucoma treatment. PMID- 29445945 TI - Spectral domain optical coherence tomography and fundus autofluorescence findings in cytomegalovirus retinitis in HIV-infected patients. AB - PURPOSE: To assess the usefulness of spectral domain optical coherence tomography (SD-OCT) and fundus autofluorescence (FAF) findings in cytomegalovirus (CMV) retinitis. STUDY DESIGN: Observational case series. METHODS: Thirteen eyes of 11 human immunodeficiency virus (HIV)-positive patients with CMV retinitis underwent full ophthalmologic examinations, SD-OCT, and 4 eyes of 4 patients underwent FAF. FAF images included short-wavelength autofluorescence (SW-AF) and near-infrared autofluorescence (IR-AF). CMV retinitis was classified into proposed categories of acute, subacute, remission, and recurrent; the acute stage was further subdivided into initial, early, and late stages. RESULTS: In the initial stage, vertical structural disruption of all retinal layers was observed by SD-OCT, and FAF showed hyperautofluorescence on SW-AF and hypoautofluorescence on IR-AF. In the early stage, SD-OCT showed significant retinal thickening; cells and debris from the retinal surface to the vitreous; enlarged vessels with/without thickened vessel walls; and highly complicated serous retinal detachment. In the late to subacute stage, features observed included rhegmatogenous retinal detachment with shrinking posterior hyaloid membrane and waving from the ellipsoid zone to the retinal pigment epithelium. In remission, FAF findings were hypoautofluorescence on SW-AF and hyperautofluorescence on IR-AF. CONCLUSION: Although the number of examined eyes was limited, SD-OCT and FAF provide new information in various stages of CMV retinitis in patients with HIV infection that is not obtainable by conventional examination and which may be of great benefit when screening for the initial stage of CMV retinitis. PMID- 29445946 TI - Paravertebral tumours of the cervicothoracic junction extending into the mediastinum: surgical strategies in a no man's land. AB - PURPOSE: Cervicothoracic paravertebral neoplasms extending into the mediastinum pose a surgical challenge due the complex regional anatomy, their biological nature, rarity and surgeon's unfamiliarity with the region. We aim to define a surgical access framework addressing the aforementioned complexities whilst achieving oncological clearance. METHODS: We carried out a retrospective review of 28 consecutive patients operated in two tertiary referral centres between 1998 and 2015. Pathology was located paravertebrally from C6 to T4 with superior mediastinum invasion. Patients were operated jointly by a spinal and a thoracic surgeon. RESULTS: Tumours were classified according to subclavian fossa involvement as anteromedial, anterolateral and posterior and according to histology in benign nerve sheath tumour group (n = 10) and malignant bone or soft tissue tumours (n = 18). Three surgical routes were utilised: (1) median sternotomy (n = 11), (2) anterior cervical transsternal approach (n = 7) and (3) high posterolateral thoracotomy (n = 10). Resection was en bloc with wide margins in 22 cases, marginally complete in 3 and incomplete in 3. Complications included Horner's syndrome (n = 3), infection (n = 2) and transient neurological deficit (n = 4). In the nerve sheath tumour group, no recurrence or reoperation took place with a median follow-up of 4.5 years. In the malignant bone and soft tissue group, 96% of the patients were alive at 1 year, 67% at 2 years and 33% at 5 years. No vascular injuries or operative related deaths were observed. CONCLUSIONS: Classification of cervicothoracic paravertebral neoplasms with mediastinal extension according to the relationship with the subclavicular fossa and dual speciality involvement allows for a structured surgical approach and provides minimal morbidity/maximum resection and satisfactory oncological outcomes.

AB - BACKGROUND: Iliac crest has long been the gold standard for lumbar fusion, but concerns over donor site morbidity have led to a wide variety of bone graft substitutes. Despite prolific research, a general consensus is yet to be reached on bone graft materials that lead to optimal fusion. PURPOSE: The purpose of this review is to evaluate the current literature for bone graft material options that maximize fusion rate in posterolateral lumbar fusion surgery. DESIGN: Systematic Review. METHODS: A PRISMA-compliant systematic review of PubMed, EMBASE, and the Web of Science was conducted. Included studies were published from January 2000 to July 2015, were clinical human research studies involving available autograft, allograft, or synthetic bone graft options in posterolateral lumbar spine fusion, and reported radiographic fusion rate as a primary end outcome. This research had no funding source and the authors have no conflicts to declare. RESULTS: 81 articles underwent full-text review, and 48 were included in this study. 18 studies assessed fusion rate by plain radiographs alone (37.5%), while 6 used CT scan (12.5%), and 24 used both (50.0%). 45 studies looked at ICBG in conjunction with LAG (29), BCP(1), APC (2), BMPs (6), or DBM (1). Aggregate mean fusion rates among these ranged from 68.0 to 91.5%. 22 studies evaluated fusion rates of LAG, either isolated (3) or combined with ceramic extenders (8), DBM (4), BMP (1), BMA (4), APC (1), or ICBG(1). Aggregate mean fusion rate ranged from 75 to 95.5%. With the exception of studies involving allograft (mean fusion rate 40.0%), the mean fusion rate for all other graft combinations exceeded 70.0%. CONCLUSIONS: While our results find that LAG+BMA provided highest fusion rate, most material options analyzed in this study provide comparable fusion outcomes. The ideal graft option must incorporate a combination of materials with osteoconductive, osteoinductive, and osteogenic properties. Our results represent the robust and dynamic nature of the current state of lumbar graft technology. These slides can be retrieved under Electronic Supplementary Material. PMID- 29445948 TI - Intraspinal neural axis abnormalities in severe spinal deformity: a 10-year MRI review. AB - PURPOSE: Documents indicated that the average prevalence of intraspinal neural axis abnormalities (INAAs) in presumed idiopathic scoliosis (PIS) patients was about 17.7%. However, paucity study focuses on the incidence of INAAs in severe spinal deformity (SSDs). In this study, we investigate the incidence of intraspinal neural axis abnormalities (IINAAs) and the clinical relevance in SSD at a single center. METHODS: All the patients with SSDs admitted for spinal surgery were evaluated from 2003 to 2014. INCLUSION CRITERIA: patients who present with coronal Cobb over 90 degrees (and/or the sagittal Cobb >= 90 degrees ); patients with whole spine magnetic resonance imaging (MRI) done preoperatively; and patients with documented clinical findings preoperatively. EXCLUSION CRITERIA: ankylosing spondylitis, adult onset scoliosis, scoliosis secondary to bone destruction, and spinal dysraphism. RESULTS: 101 patients fulfilled the criteria were included. 43 patients were detected with INAAs (42.6%, 43/101). The most common INAAs was syrinx (S) (16/43, 37.2%). Of which, 43.7% (7/16), 37.5% (6/16), and 18.7% (3/16) were spindle, slit, and swelling types, respectively. Most of them were located in thoracic (6/16, 37.5%) and cervical (5/16, 31.3%) region. MRI revealed Chiari malformation with syringomyelia (C + S) in ten patients (10/43, 23.2%), Chiari malformation (C) in 6 patients (6/43, 13.9%) and others in 11 patients (11/43, 25.6%). As to the etiology, most patients with INAAs were PIS (34/43, 79.1%). On clinical examination, 16 of 101 patients (16/101, 15.8%) had abnormal neurologic signs. 15 of 16 patients (15/16, 93.7%) with abnormal neurologic signs had INAAs on MRI. On the other hand, 28 of 43 patients (28/43, 65.1%) with INAAs on MRI presented neurologically intact. 28 of 85 patients (28/85, 32.9%) with neurologically intact were detected with INAAs on MRI. CONCLUSION: The incidence of INAAs in SSDs was 42.6%. 65.1% of them present intact neurologic status. The most common neural anomaly was syrinx. Preoperative whole spine MRI must be beneficial for SSDs even in the absence of neurological findings. These slides can be retrieved under Electronic Supplementary Material. PMID- 29445949 TI - Postoperative K-line conversion from negative to positive is independently associated with a better surgical outcome after posterior decompression with instrumented fusion for K-line negative cervical ossification of the posterior ligament. AB - PURPOSE: Addition of posterior instrumented fusion to laminoplasty (posterior decompression with instrumented fusion: PDF) can improve the surgical outcome of patients with K-line (-) cervical ossification of the longitudinal ligament (OPLL) compared with laminoplasty alone. We sought to elucidate the factors that are significantly associated with a better outcome after PDF for K-line (-) OPLL. METHODS: The present study included 38 patients who underwent PDF for K-line (-) OPLL and were followed up for at least 1 year after surgery. Clinical outcome was assessed using Japanese Orthopedic Association (JOA) scores for cervical myelopathy and the recovery rate was calculated. Patients who belonged to the upper quartile of all the patients according to rank order of the JOA score recovery rate were considered to have a good outcome. The correlations between good outcome, patient factors and imaging assessments were analyzed statistically. RESULTS: Univariate analyses showed that postoperative conversion of K-line from (-) to (+) (p = 0.004), no increase in the sagittal vertical axis from the center of gravity of the head to C7 (p = 0.07), and a lower grade of preoperative intramedullary T2-signal intensity (p = 0.03) were candidates for the association. Stepwise logistic regression analysis revealed that postoperative K-line conversion from (-) to (+) is an independent factor that is significantly associated with a better surgical outcome (p = 0.04). CONCLUSION: Postoperative K-line conversion from (-) to (+) is a factor independently associated with a better surgical outcome. These slides can be retrieved under Electronic Supplementary material. PMID- 29445950 TI - The importance of proximal femoral angle on sagittal balance and quality of life in children and adolescents with high-grade lumbosacral spondylolisthesis. AB - PURPOSE: Previous studies did not specifically assess the influence of proximal femoral angle (PFA) on sagittal balance in high-grade spondylolisthesis (HGS). In addition, the relationship between PFA and quality of life (QOL) remains unknown. This study determines if increased PFA is associated with decreased QOL and sagittal balance in lumbosacral HGS. METHODS: This retrospective case-control study was performed on a cohort of 56 normal subjects and 42 patients with HGS. Initially, PFA was measured twice by 3 raters in a random subset of 30 subjects (15 normal and 15 HGS) to determine the intrarater and interrater reliability of the measurement technique. PFA was then measured for all subjects. For the 42 patients with HGS, QOL was assessed from the SRS-22 questionnaire, in addition to the evaluation of the spino-pelvic balance. RESULTS: The intrarater and interrater intraclass correlation coefficients for the measurement of PFA were, respectively, 0.951 and 0.958, suggesting excellent reliability. PFA was significantly higher in HGS patients (8.3 degrees +/- 6.7 degrees ; range - 5 degrees to 24 degrees ) when compared to normal subjects (3.0 degrees +/- 3.1 degrees ; range - 6 degrees to 10 degrees ). The PFA in HGS was 5.6 degrees +/- 5.6 degrees (range - 5 degrees to 18 degrees ), 8.9 degrees +/- 6.7 degrees (range - 2 degrees to 24 degrees ), and 14.0 degrees +/- 6.0 degrees (range 7 degrees -23 degrees ) in type 4 (balanced pelvis), type 5 (unbalanced pelvis/balanced spine), and type 6 (unbalanced pelvis and spine) subjects, respectively. There were, respectively, 23.5% (4/17), 26.3% (5/19), and 83.3% (5/6) of HGS patients with abnormal PFA >= 10 degrees in type 4, type 5, and type 6 subgroups. Increased PFA in HGS patients was related with deteriorating self-image, pain, function and total SRS-22 score, as well as with increasing pelvic tilt and decreasing sacral slope. CONCLUSION: A PFA >= 10 degrees is proposed as a criterion to define abnormal PFA. PFA was increased in HGS and increased along with deteriorating sagittal balance and QOL. PFA is a clinically relevant parameter of sagittal balance, and can be useful in the evaluation and management of patients with HGS. PMID- 29445951 TI - Full endoscopic lumbar interbody fusion (FELIF): technical note. AB - PURPOSE: Interbody fusion by open discectomy is the usual treatment for degenerative lumbar disease but requires a relatively long recovery period. Prevalent several interbody fusion methods have shown limitations by its own character. Full endoscopic lumbar interbody fusion (FELIF) has advantages in direct decompression of pathology with minimal invasive technique. We report novel technique of endoscopic fusion method through full guided with endoscopic view monitoring system. METHODS: The authors provide an introduction of FELIF technique followed by a description of the technical steps with discussion on its indications and advantages. In particular, tips to shorten operation time, simplify technical steps, and avoid complications are also presented. CONCLUSIONS: FELIF is a safe and effective interbody fusion option to decompress the lumbar exiting nerve root and ventral side of dura directly with minimal invasive situation.

AB - The widely use of IoT technologies in healthcare services has pushed forward medical intelligence level of services. However, it also brings potential privacy threat to the data collection. In healthcare services system, health and medical data that contains privacy information are often transmitted among networks, and such privacy information should be protected. Therefore, there is a need for privacy-preserving data collection (PPDC) scheme to protect clients (patients) data. We adopt (a,k)-anonymity model as privacy pretection scheme for data collection, and propose a novel anonymity-based PPDC method for healthcare services in this paper. The threat model is analyzed in the client-server-to-user (CS2U) model. On client-side, we utilize (a,k)-anonymity notion to generate anonymous tuples which can resist possible attack, and adopt a bottom-up clustering method to create clusters that satisfy a base privacy level of (a1,k1) anonymity. On server-side, we reduce the communication cost through generalization technology, and compress (a1,k1)-anonymous data through an UPGMA based cluster combination method to make the data meet the deeper level of privacy (a2,k2)-anonymity (a1 >= a2, k2 >= k1). Theoretical analysis and experimental results prove that our scheme is effective in privacy-preserving and data quality. PMID- 29445953 TI - Competition between abiogenic Al3+ and native Mg2+, Fe2+ and Zn2+ ions in protein binding sites: implications for aluminum toxicity. AB - Abiogenic aluminum has been implicated in some health disorders in humans. Protein binding sites containing essential metals (mostly magnesium) have been detected as targets for the "alien" Al3+. However, the acute toxicity of aluminum is very low. Although a substantial body of information has been accumulated on the biochemistry of aluminum, the underlying mechanisms of its toxicity are still not fully understood. Several outstanding questions remain unanswered: (1) Why is the toxicity of aluminum, unlike that of other "alien" metal cations, relatively low? (2) Apart from Mg2+ active centers in proteins, how vulnerable are other essential metal binding sites to Al3+ attack? (3) Generally, what factors do govern the competition between 'alien" Al3+ and cognate divalent metal cations in metalloproteins under physiologically relevant conditions? Here, we endeavor to answer these questions by studying the thermodynamic outcome of the competition between Al3+ and a series of biogenic metal cations, such as Mg2+, Fe2+ and Zn2+, in model protein binding sites of various structures, compositions, solvent exposure and charge states. Density functional theory calculations were employed in combination with polarizable continuum model computations. For the first time, the presence of different Al3+ soluble species at physiological pH was properly modeled in accordance with experimental observations. The results suggest that a combination of concentration and physicochemical factors renders the Al3+ -> M2+ (M = Mg, Fe, Zn) substitution and subsequent metalloenzyme inhibition a low occurrence event at ambient pH: the more active aluminum species, [Al(H2O)6]3+, presents in very minute quantities at physiological conditions, while the more abundant soluble aluminum hydrate, {[Al(OH-)4](H2O)2}-, appears to be thermodynamically incapable of substituting for the native cation. PMID- 29445954 TI - Normal boundary intersection applied as multivariate and multiobjective optimization in the treatment of amoxicillin synthetic solution. AB - Amoxicillin is a useful antibiotic to combat bacterial infections. However, this drug can cause serious problems when discarded in waterways due to its great bioaccumulation potential. This compound can be treated via advanced oxidation processes (AOPs), which are capable of converting amoxicillin into carbon dioxide and water. In this context, the use of ozone as an oxidizer has excelled in amoxicillin degradation. This paper aims at treating a synthetic solution of amoxicillin (0.1 g L-1) in a reactor with ozone bubbling. A Design of Experiment (DoE) with a response surface known as Central Composite Design (CCD) was used to optimize the treatment process. In addition, a Normal Boundary Intersection (NBI) method was used in the construction of a Pareto boundary chart. Results after 1-h treatment showed a reduction of 53% of the initial organic matter from a designed model using factors, such as pH, ozone generator power, and O3 flow. A model was built from the CCD with score of 0.9929. Thus, the model was able to represent the real scenario with confidence. PMID- 29445955 TI - Fifty shades of white: how white feather brightness differs among species. AB - White colouration is a common and important component of animal visual signalling and camouflage, but how and why it varies across species is poorly understood. White is produced by wavelength-independent and diffuse scattering of light by the internal structures of materials, where the degree of brightness is related to the amount of light scattered. Here, we investigated the morphological basis of brightness differences among unpigmented pennaceous regions of white body feathers across 61 bird species. Using phylogenetically controlled comparisons of reflectance and morphometric measurements, we show that brighter white feathers had larger and internally more complex barbs than duller white feathers. Higher brightness was also associated with more closely packed barbs and barbules, thicker and longer barbules, and rounder and less hollow barbs. Larger species tended to have brighter white feathers than smaller species because they had thicker and more complex barbs, but aquatic species were not significantly brighter than terrestrial species. As similar light scattering principals affect the brightness of chromatic signals, not just white colours, these findings help broaden our general understanding of the mechanisms that affect plumage brightness. Future studies should examine how feather layering on a bird's body contributes to differences between brightness of white plumage patches within and across species.

AB - Hybrid heterojunction solar cells (HHSCs) have gained extensive research and attention due to simple device structure and low-cost technological processes. Here, HHSCs are presented based on a highly transparent conductive polymer poly(3,4ethylenedioxythiophene):poly(styrenesulfonate)(PEDOT:PSS) directly spin coated on an n-type crystalline silicon with microscale surface textures, which are prepared by traditional chemical etching. We have studied interface properties between PEDOT:PSS and textured n-Si by varying coating conditions. Final power conversion efficiency (PCE) could arrive at 8.54% by these simple solution-based fabrication processes. The high conversion efficiency is attributed to the fully conformal contact between PEDOT:PSS film and textured silicon. Furthermore, the reflectance of the PEDOT:PSS layer on textured surface is analyzed by changing film thickness. In order to improve the performance of the device, silver nanowires were employed as electrodes because of its better optical transmittance and electrical conductivity. The highest PCE of 11.07% was achieved which displayed a 29.6% enhancement compared with traditional silver electrodes. These findings imply that the combination of PEDOT:PSS film and silver nanowire transparent electrodes pave a promising way for realizing high efficiency and low-cost solar cells. PMID- 29445958 TI - Histopathological and Behavioral Assessments of Aging Effects on Stem Cell Transplants in an Experimental Traumatic Brain Injury. AB - Traumatic brain injury (TBI) displays cognitive and motor symptoms following the initial injury which can be exacerbated by secondary cell death. Aging contributes significantly to the morbidity of TBI, with higher rates of negative neurological and behaviors outcomes. In the recent study, young and aged animals were injected intravenously with human adipose-derived mesenchymal stem cells (hADSCs) (Tx), conditioned media (CM), or vehicle (unconditioned media) following TBI. The beneficial effects of hADSCs were analyzed using various molecular and behavioral techniques. More specially, DiR-labeled hADSCs were used to observe the biodistribution of the transplanted cells. In addition, a battery of behavior tests was conducted to evaluate the neuromotor function for each treatment group and various regions of the brain were analyzed utilizing Nissl, hematoxylin and eosin (H&E), and human nuclei (HuNu) staining. Finally, flow cytometry was also performed to determine the levels of various proteins in the spleen. Here, we discuss the protocols for characterizing the histopathological and behavioral effects of transplanted stem cells in an animal model of TBI, with an emphasis on the role of aging in the therapeutic outcomes. PMID- 29445957 TI - Treating Immune-Related Epilepsy. AB - PURPOSE OF REVIEW: This review explores different treatment modalities for immune mediated epilepsy, including epilepsy caused by autoantibodies as well as epilepsy in the context of systemic autoimmune disease. RECENT FINDINGS: Autoimmune epilepsy is an increasingly recognized entity. Conventional treatments for epilepsy, such as antiseizure medications and epilepsy surgery, are less successful in treating epilepsy caused by autoimmune disease. Immunomodulatory therapies such as corticosteroids, intravenous immunoglobulin, and plasma exchange are generally more successful in treating immune-mediated epilepsy than conventional epilepsy therapies. Autoimmune epilepsy should be considered as a possible etiology for patients with frequent seizures of unknown etiology. The response to immunotherapies is often promising, particularly in patients with antibodies to neuronal cell surface antigens.

Although moths and butterflies are among the first animal models in which this self-eating process was described, only in recent years autophagy has been analyzed in detail in these insects. In particular, the silkworm Bombyx mori, which represents a well-studied model among Lepidoptera, provides a wide repertoire of cellular and molecular tools useful for studying the occurrence of autophagy and for evaluating its role in postembryonic development. Here, we describe some morphological, biochemical, and molecular methods to monitor autophagy in silkworm organs. PMID- 29445960 TI - Is percutaneous kyphoplasty the better choice for minimally invasive treatment of neurologically intact osteoporotic Kummell's disease? A comparison of two minimally invasive procedures. AB - PURPOSE: The purpose of this study was to compare and evaluate the safety and efficacy of percutaneous vertebroplasty at a hyperextension position (PVPHP) and percutaneous kyphoplasty at a hyperextension position (PKPHP) for the treatment of osteoporotic Kummell's disease. METHODS: This study was a retrospective, single-centre study. There were 35 patients with osteoporotic Kummell's disease who were analyzed. Twenty-two of them underwent PVPHP and the other 13 patients underwent PKPHP from January 2013 to January 2015. The volume of bone cement injection and operation costs were compared. We compared the visual analogue score (VAS) and vertebral Cobb's angle at pre-operation, the second day after operation, and the final follow-up. We compared the Oswestry disability index (ODI) score at the pre-operation and the final follow-up. RESULTS: There were no significant differences in gender, age, course of disease, bone mineral density (BMD), and mean follow-up time between the two groups (P > 0.05). Regarding the costs of the operation, the PKPHP group was significantly higher than the PVPHP group (P < 0.05). Compared with the pre-operation (P < 0.05), the post-operative ODI score, VAS, and Cobb's angle of the two groups were improved significantly. Even though the correction of Cobb's angle in the PKPHP group was slightly better than the PVPHP position group, there were no significant differences between two groups (P > 0.05). At the final follow-up, the Cobb's angle was increased in both groups, but there was no significant difference (P > 0.05). There was no significant difference in the bone cement leakage rate between the two groups (P > 0.05). CONCLUSION: For the treatment of Kummell's disease, PVPHP and PKPHP are both safe and effective, but PVPHP is more economical and can be considered a preferred method of treatment. PMID- 29445961 TI - Application of combined porous tantalum scaffolds loaded with bone morphogenetic protein 7 to repair of osteochondral defect in rabbits. AB - PURPOSE: Porous tantalum (PT) has been widely used in orthopaedic applications for low modulus of elasticity, excellent biocompatibility, and the microstructures similar to cancellous bone. In order to improve the biological activity of PT, biologically active factors can be combined with the material. The purpose of this study was to investigate if bone morphogenetic protein 7 (BMP 7) modifications could enhance the repairing of cartilage of PT in osteochondral defect in medial femoral condyle of rabbits. METHODS: A cylindrical osteochondral defect model was created on the animal medial femoral condyle of and filled as follows: PT modified with BMP-7 for MPT group, non-modified PT for the PT group, while no implants were used for the blank group. The regenerated osteochondral tissue was assessed and analyzed by histological observations at four, eight and 16 weeks post-operation and evaluated in an independent and blinded manner by five different observers using a histological score. Osteochondral and subchondral bone defect repair was assessed by micro-CT scan at 16 weeks post operation, while the biomechanical test was performed at 16 weeks post-operation. RESULTS: Briefly, higher overall histological score was observed in the MPT group compared to PT group. Furthermore, more new osteochondral tissue and bone formed at the interface and inside the inner pores of scaffolds of the MPT group compared to PT group. Additionally, the micro-CT data suggested that the new bone volume fractions and the quantity and quality of trabecular bone, as well as the maximum release force of the bone, were higher in the MPT group compared to PT group. CONCLUSIONS: We demonstrated that the applied modified PT with BMP-7 promotes excellent subchondral bone regeneration and may serve as a novel approach for osteochondral defects repair. PMID- 29445962 TI - Impact of surgical case order on peri-operative outcomes for total joint arthroplasty. AB - INTRODUCTION: There is growing support in the literatures that peri-operative outcomes are adversely affected by surgical case order in some certain surgical procedures. This study aimed to examine if similar phenomenon is also shared in total joint arthroplasty (TJA). METHODS: A total of 6548 joints (5183 patients) treated with primary TJA by a total of five surgeons at our institution from December 2011 to December 2015 were retrospectively reviewed in this study. Demographic data, operative duration, blood loss, peri-operative adverse events, medical cost, and length of hospital stay were collected and analyzed. Logistic regression was used to determine risk factors for adverse events. RESULTS: Of the 6548 cases in this cohort, 1643 TJAs were classified as first round cases, 1744 TJAs were second round cases, 1600 TJAs were third round cases, and 1561 TJAs were fourth or later round cases. Mean operating time was shorter in the intermediate cases (45.0 vs. 41.0 vs. 41.8 vs. 54.1 min, P < 0.01). Peri operative arthroplastic adverse events were increased in later surgical cases (2.07% vs. 2.18% vs. 3.06% vs. 4.87%, P < 0.01). Later case order (OR = 1.40 [95% CI: 1.22-1.61], P < 0.01) was a significant risk factor of arthroplastic adverse events. Patients undergoing TJA later in the day were more likely to have longer length of stay and higher cost than earlier cases. Peri-operative systemic complications and blood loss did not significantly differ between groups. CONCLUSION: Surgical case order is an independent risk factor for arthroplastic adverse events in TJA. TJA procedures performed later in the day have a higher risk for arthroplastic adverse events, but not for systematic adverse events. Significantly increased operative time, higher cost, and longer LOS were noted for fourth or later TJA cases. Data in our study reveals that performing more than three TJAs within a single day may imply compromised outcomes. PMID- 29445963 TI - Incomplete pure sensory stroke due to a pontine lacune. PMID- 29445964 TI - Different Methods for Modelling Severe Hypoglycaemic Events: Implications for Effectiveness, Costs and Health Utilities. AB - BACKGROUND: Clinical trials report severe hypoglycaemic events as the number of patients with at least one event out of the total randomised or number of events for a given total exposure. Different network meta-analysis models have been used to analyse these different data types. OBJECTIVE: This aim of this article was to establish the impact of using the different models on effectiveness, costs and health utility estimates. METHODS: We analysed a dataset used in a recent network meta-analysis of severe hypoglycaemic events conducted to inform National Institute for Health and Care Excellence recommendations regarding basal insulin choice for patients with type 1 diabetes mellitus. We fitted a model with a binomial likelihood reporting odds ratios (using a logit link) or hazard ratios (complementary log-log link), a model with a Poisson likelihood reporting hazard ratios and a shared-parameter model combining different types of data. We compared the results in terms of relative effects and resulting cost and disutility estimates. RESULTS: Relative treatment effects are similar regardless of which model or scale is used. Differences were seen in the probability of having an event on the baseline treatment with the logit model giving a baseline probability of 0.07, the complementary log-log 0.17 and the Poisson 0.29. These translate into differences of up to L110 in the yearly cost of a hypoglycaemic event and 0.004 in disutility. CONCLUSION: While choice of network meta-analysis model does not have a meaningful impact on relative effects for this outcome, care should be taken to ensure that the baseline probabilities used in an economic model are accurate to avoid misrepresenting costs and effects. PMID- 29445965 TI - Traumatic subarachnoid hemorrhage related to ophthalmic artery avulsion: a case report. AB - We present a case of ophthalmic artery (OA) traumatic avulsion, leading to a post traumatic subarachnoid hemorrhage (SAH) with ventricular blood invasion and hydrocephalus, mimicking an internal carotid aneurysm rupture. This is the third case of such an event reported in literature and the first without orbital fractures and optic nerve avulsion. Conservative treatment was sufficient for the avulsion, but surgery was needed for the coexisting eye luxation. Traumatic OA avulsion is a rare but possible event and should be suspected in case of basal cisterns SAH, evidence of orbital trauma and CT angiogram or angiographic absence of opacification of the OA. PMID- 29445966 TI - Thoracic ossification of ligamentum flavum manifesting holocord syringomyelia: case report. AB - It has been reported that syringomyelia is rarely associated with degenerative spinal disorders, but the case of holocord syringomyelia is never reported. We here present a case of a 59-year-old woman with right shoulder pain, dysesthesia of the right hand, and gait disturbance. Radiographically, examinations of the spine demonstrated holocord syringomyelia with ossification of ligamentum flavum at T2/3 level. Holocord syringomyelia was reduced remarkably after posterior decompression at the T2/3 level, and her symptoms also improved. We speculated that holocord syringomyelia might have developed due to craniospinal pressure dissociation caused by focal compression of dural sac from extradural degenerative change. PMID- 29445967 TI - The use of free nonvascularized fibular graft in the induced membrane technique to manage post-traumatic bone defects. AB - PURPOSE: The aim of the present study is to assess the results of free nonvascularized fibular graft in the induced membrane technique to manage bone defects. MATERIALS AND METHODS: Fifteen patients with segmental skeletal defects were treated by the induced membrane technique using free nonvascularized fibular graft. The ages ranged from 20 to 48 years with an average of 32 years. The cause of the defects was post-traumatic bone loss in all cases. The defects were located in the distal femur in nine cases, proximal tibia in two cases and middle third of the tibia in four cases. The defects ranged from 5 to 14 cm with an average of 8 cm. All cases were treated by the induced membrane technique in two stages. Autogenous cancellous bone graft and free nonvascularized fibular graft were used to fill the defect in the second stage of surgery. RESULTS: All cases healed without additional procedures after the second stage except in two cases. The time-to-bone union ranged from 4 to 13 months with an average of 7 months. After physiotherapy, all cases regained good range of ankle and knee movements except two cases. The complications included nonunion of the graft in two cases, deep wound infection in one case, and chronic pain along the iliac crest in one case. No cases were complicated by implant failure or refracture. CONCLUSION: The use of free nonvascularised fibular graft in the induced membrane technique reduces the time of healing and improves the final outcome. PMID- 29445968 TI - Arthroscopic direct meniscal extrusion reduction: surgical tips to reduce persistent meniscal extrusion in meniscal root repair. AB - Meniscal extrusion (ME) is defined as extension of the meniscal margin by at least 3 mm beyond the tibial margin. The main purpose of meniscal root repair is to restore the anatomy and function of the meniscus. Therefore, the reduction in the ME is one of the important objective outcomes. Nevertheless, the reduced meniscal extrusion was obtained in limited patients after meniscal root repair. This technical note described the arthroscopic direct meniscal extrusion reduction as surgical tips to reduce persistent meniscal extrusion in posterior meniscal root repair. PMID- 29445970 TI - Flower palate ultrastructure of the carnivorous plant Genlisea hispidula Stapf with remarks on the structure and function of the palate in the subgenus Genlisea (Lentibulariaceae). AB - In the genus Genlisea as well as in its sister genus Utricularia, the palate probably plays a key role in providing the colour, mechanical and olfactory stimuli to attract insect pollinators and to guide them to the generative structures and the nectary spur. However, information about the micro-morphology of the palate of Genlisea is scarce. This study aims to examine the structure of the palate in Genlisea hispidula in detail as well as the palate from other five species from the subgenus Genlisea. In particular, its aim is to ascertain whether these palates function as an area for the osmophores in the flower or whether they produce nectar. We showed that the palate in all of the species that were examined was the glandular type and that it had capitate, glandular trichomes, which had a similar general architecture across the species that were examined. No nectar secretion was observed on the palates. The ultrastructure of the palate trichomes showed that the palate glandular trichomes most probably function as scent glands that produce an olfactory stimulus for flower pollinators. PMID- 29445969 TI - The best cited articles of the European Journal of Orthopaedic Surgery and Traumatology (EJOST): a bibliometric analysis. AB - European Journal of Orthopaedic Surgery and Traumatology (EJOST) was founded in 1991. It was initially named as Orthopedie-Traumatologie, and since then it is dedicated in sharing knowledge and new evidence in the field of orthopaedics. Within 28 volumes and 157 issues, it has published 3218 scientific articles. In the early years of its distribution, published articles were in French, while the last two decades EJOST only hosts English articles between its pages. By the very beginning of its launch, it has been publishing high-quality research articles in all orthopaedic subspecialties and has gradually become one of the leading journals in its specific subject area. The aim of this study was to identify, analyse and categorize the most frequently cited articles, published by EJOST since its launch. PMID- 29445971 TI - Progesterone PLGA/mPEG-PLGA Hybrid Nanoparticle Sustained-Release System by Intramuscular Injection. AB - PURPOSE: To prepare sustained-release PLGA/mPEG-PLGA hybrid nanoparticles of progesterone (PRG), and evaluate the descending required administration dosage in vivo. METHODS: PRG hybrid nanoparticles (PRG H-NPs) based on PLGA/mPEG-PLGA were compared with PRG nanoparticles (PRG-NPs) of pure PLGA as the matrix and PRG-oil solutions. Nanoparticles (NPs) were formed by the method of nanoemulsion, and the pharmacokinetics of the sustained-release PRG H-NPs in male Sprague dawley (SD) rats were investigated. The rats were randomly divided into four groups, each group received: single dose of PRG H-NPs (14.58 mg/kg, i.m.) and PRG-NPs (14.58 mg/kg, i.m.), repeated dosing for 7 days of PRG-oil (2.08 mg/kg, i.m.) solution (Oil-L) and a higher dosage of PRG-oil (6.24 mg/kg, i.m.) solution (Oil-H), respectively. RESULTS: In the pharmacokinetic test, the PRG H-NPs exhibited a comparatively good sustained-release effect against the PRG-NPs without mPEG-PLGA and PRG-oil solution. The pharmacokinetic parameters of the PRG H-NPs, PRG-NPs, Oil-L and Oil-H were AUC0-t(ng.h.mL-1) 8762.1, 1546.1, 1914.5, and 12,138.9, t1/2 (h)52.7, 44.1, 8.4 and 44.6 respectively. CONCLUSIONS: Owing to the modification of PEG, PRG H-NPs can act as safe delivery platforms for sustained-release of drugs with a lower dosage required. PMID- 29445972 TI - Design and validation of an osteochondral bioreactor for the screening of treatments for osteoarthritis. AB - Bioreactors are systems that can be used to monitor the response of tissues and cells to candidate drugs. Building on the experience developed in the creation of an osteochondral bioreactor, we have designed a new 3D printed system, which allows optical access to the cells throughout testing for in line monitoring. Because of the use of 3D printing, the fluidics could be developed in the third dimension, thus maintaining the footprint of a single well of a typical 96 well plate. This new design was optimized to achieve the maximum fluid transport through the central chamber, which corresponds to optimal nutrient or drug exposure. This optimization was achieved by altering each dimension of the bioreactor fluid path. A physical model for optimized drug exposure was then created and tested. PMID- 29445973 TI - Is heart rate response a reliable marker of adenosine-induced coronary hyperemia? AB - Introduction Growing evidence supports ischemia-guided management of chest pain, with invasive and non-invasive tests reliant upon achieving adenosine-induced coronary hyperemia (defined as increased blood flow to an organ's perfusion bed). In the non-invasive setting, surrogate markers of hyperemia, such as increases in heart rate, are often used, despite not being formally validated. We tested whether heart rate and other non-invasive indices are reliable markers of coronary hyperemia. Methods The first part involved Doppler flow-based validation of the best pressure-wire markers of hyperemia in 53 patients. Subsequently, using these validated pressure-derived parameters, 265 pressure-wire traces were analysed to determine whether heart rate and other non-invasive parameters correlated with hyperemia. Results In the flow derivation cohort, the best determinant of hyperemia came from having 2 out of 3 of: (1) Ventriculisation of the distal pressure waveform, (2) disappearance of distal dicrotic pressure notch, (3) separation of mean aortic and distal pressures. Within the 244 patients demonstrating hyperemia, non-invasive markers of hyperemia, such as change in heart rate (p = 0.77), blood pressure (p = 0.60) and rate-pressure product (p = 0.86), were poor correlates of coronary hyperemia, with only 37.3% demonstrating a >= 10% increase in heart rate that is commonly used to adjudge adenosine-induced hyperemia in the non-invasive setting. Conclusions We demonstrate, by correlation with Doppler-flow data, a validated method of identifying coronary hyperemia within the catheter laboratory using the pressure wire. We subsequently show that non-invasive parameters, such as heart rate change, are poor predictors of coronary hyperemia during stress imaging protocols that rely upon achieving adenosine-induced hyperemia. PMID- 29445974 TI - Impact of acquisition and interpretation on total inter-observer variability in echocardiography: results from the quality assurance program of the STAAB cohort study. AB - Variability related to image acquisition and interpretation is an important issue of echocardiography in clinical trials. Nevertheless, there is no broadly accepted standard method for quality assessment of echocardiography in clinical research reports. We present analyses based on the echocardiography quality assurance program of the ongoing STAAB cohort study (characteristics and course of heart failure stages A-B and determinants of progression). In 43 healthy individuals (mean age 50 +/- 14 years; 18 females), duplicate echocardiography scans were acquired and mutually interpreted by one of three trained sonographers and an EACVI certified physician, respectively. Acquisition (AcV), interpretation (InV), and inter-observer variability (IOV; i.e., variability between the acquisition-interpretation sequences of two different observers), were determined for selected M-mode, B-mode, and Doppler parameters. We calculated Bland-Altman upper 95% limits of absolute differences, implying that 95% of measurement differences were smaller/equal to the given value: e.g. LV end-diastolic volume (mL): 25.0, 25.0, 27.9; septal e' velocity (cm/s): 3.03, 1.25, 3.58. Further, 90, 85, and 80% upper limits of absolute differences were determined for the respective parameters. Both, acquisition and interpretation, independently and sizably contributed to IOV. As such, separate assessment of AcV and InV is likely to aid in echocardiography training and quality-assurance. Our results further suggest to routinely determine IOV in clinical trials as a comprehensive measure of imaging quality. The derived 95, 90, 85, and 80% upper limits of absolute differences are suggested as reproducibility targets of future studies, thus contributing to the international efforts of standardization in quality assurance. PMID- 29445975 TI - Factors of U.S. Hospitals Associated with Improved Profit Margins: An Observational Study. AB - BACKGROUND: Hospitals face financial pressure from decreased margins from Medicare and Medicaid and lower reimbursement from consolidating insurers. OBJECTIVES: The objectives of this study are to determine whether hospitals that became more profitable increased revenues or decreased costs more and to examine characteristics associated with improved financial performance over time. DESIGN: The design of this study is retrospective analyses of U.S. non-federal acute care hospitals between 2003 and 2013. SUBJECTS: There are 2824 hospitals as subjects of this study. MAIN MEASURES: The main measures of this study are the change in clinical operating margin, change in revenues per bed, and change in expenses per bed between 2003 and 2013. KEY RESULTS: Hospitals that became more profitable had a larger magnitude of increases in revenue per bed (about $113,000 per year [95% confidence interval: $93,132 to $133,401]) than of decreases in costs per bed (about - $10,000 per year [95% confidence interval: - $28,956 to $9617]), largely driven by higher non-Medicare reimbursement. Hospitals that improved their margins were larger or joined a hospital system. Not-for-profit status was associated with increases in operating margin, while rural status and having a larger share of Medicare patients were associated with decreases in operating margin. There was no association between improved hospital profitability and changes in diagnosis related group weight, in number of profitable services, or in payer mix. Hospitals that became more profitable were more likely to increase their admissions per bed per year. CONCLUSIONS: Differential price increases have led to improved margins for some hospitals over time. Where significant price increases are not possible, hospitals will have to become more efficient to maintain profitability. PMID- 29445976 TI - An equivalence study of interview platform: Does videoconference technology impact medical school acceptance rates of different groups? AB - Web-based interviewing may be an effective element of a medical school's larger approach to promotion of holistic review, as recommended by the Association of American Medical Colleges, by facilitating the feasibility of including rural and community physicians in the interview process. Only 10% of medical schools offer videoconference interviews to applicants and little is known about the impact of this interview modality on the admissions process. This study investigated the impact of overall acceptance rates using videoconference interviews and face-to face interviews in the medical school selection process using an equivalence trial design. The University of New Mexico School of Medicine integrated a videoconferencing interview option for community and rural physician interviewers in a pseudo-random fashion during the 2014-2016 admissions cycles. Logistic regression was conducted to examine whether videoconference interviews impacted acceptance rates or the characteristics of accepted students. Demographic, admissions and diversity factors were analyzed that included applicant age, MCAT score, cumulative GPA, gender, underrepresented in medicine, socioeconomic status and geographic residency. Data from 752 interviews were analyzed. Adjusted rates of acceptance for face-to-face (37.0%; 95% CI 28.2, 46.7%) and videoconference (36.1%; 95% CI 17.8, 59.5%) interviews were within an a priori +/- 5% margin of equivalence. Both interview conditions yielded highly diverse groups of admitted students. Having a higher medical college admission test score, grade point average, and self-identifying as disadvantaged increased odds of admission in both interview modalities. Integration of the videoconference interview did not impact the overall acceptance of a highly diverse and qualified group of applicants, and allowed rural and community physicians to participate in the medical school interview process as well as allowed campus faculty and medical student committee members to interview remotely.

PMID- 29445978 TI - Positive Developmental Changes after Transition to High School: Is Retrospective Growth Correlated with Measured Changes in Current Status of Personal Growth? AB - The transition to high school is generally considered as a stressful turning point in adolescent development, but some students experience personal growth (i.e., positive developmental changes) through that experience. It is important to examine the mechanism behind such positive changes to understand various developmental patterns of adolescents during the transition. However, the concept of growth in this research area remains unexplored. Some researchers have questioned whether retrospective, self-reported growth reflects actual positive changes in the perception of personal growth. We elaborated on the concept of growth after high school transition by examining whether retrospective appraisal of personal growth after transition to high school is correlated with measured change in growth. Two hundred and sixty-two Japanese adolescents (aged 14-16 years, 50% girls) participated in surveys right before and right after transition. We assessed five domains of growth, including improved relating to others, identification of new possibilities, increased sense of personal strength, spiritual growth, and greater appreciation of life. The results showed that retrospective assessment of growth and measured change during transition were positively associated, provided the adolescents reported the transition as an important turning point in their lives. Adolescents who experienced salient positive changes across the transition were more likely to engage in intrusive and deliberate rumination and social support than adolescents who reported fewer changes. In summary, retrospective growth covaried with measured change only when adolescents perceived the transition as impactful in their lives. PMID- 29445979 TI - Hispanic Immigrant Father Involvement with Young Children in the United States: A Comparison with US-Born Hispanic and White non-Hispanic Fathers. AB - Objectives Fathering is known to foster child development and health, yet evidence on Hispanic immigrant fathers' involvement with their young children is sparse. This study assessed disparities in pregnancy intendedness and father involvement with children ages 0-4 among Hispanic immigrant co-resident fathers versus two reference groups: US-born Hispanic and US-born White fathers. We hypothesized that differentials in involvement were associated with socioeconomic and cultural factors. Methods Using 2011-2013 data from the National Survey of Family Growth (N = 598), we performed bivariate, logistic and linear regression analyses to assess disparities in pregnancy intendedness and five father involvement outcomes (physical care, warmth, outings, reading and discipline). The models controlled for socio-economic, structural, health and cultural covariates. Results Pregnancy intendedness did not differ significantly between Hispanic immigrant fathers and the two reference groups. Compared with US-born Hispanics, unadjusted models showed that immigrant fathers were less likely to engage in physical care, warmth and reading, (p <= 0.05) though the differences were attenuated when controlling for covariates. Hispanic immigrant fathers were less likely than US-born White fathers to engage in each of the father involvement outcomes (p <= 0.05), with the disparity in reading to their child persisting even after controlling for all covariates. Conclusions for Practice We found marked socio-economic and cultural differences between Hispanic immigrant and US-born Hispanic and White fathers which contribute to disparities in father involvement with their young children. Hispanic immigrant status is an important determinant of involved fathering and should be taken into account when planning public health policies and programs. PMID- 29445980 TI - Challenges and Facilitators to Promoting a Healthy Food Environment and Communicating Effectively with Parents to Improve Food Behaviors of School Children. AB - Background Childhood obesity is a major public health concern and families play an important role. Improving strategies to reach parents and directing tailored nutrition education to them is needed. Purpose To investigate the challenges and facilitators to promoting a healthy environment at home and to identify communication preferences to inform intervention strategies for effectively reaching low-income urban minority families. Procedure Semi-structured focus group interviews were conducted with four groups involving 16 low-income urban parents (94% female; 88% Hispanic/Latino, 12% African American) of elementary school children. Interviews were transcribed and analyzed applying Social Cognitive Theory and using in-vivo coding. Main Findings The most common barriers to parents providing healthy foods to their children were accommodating child preferences and familial opposition. Parents showed intentionality to engage in healthy behaviors, and often shared procedural knowledge for reaching health goals. The analyses of desired communication channels yielded major preferences: tailored information, information provided through multiple mediums, appropriate duration/frequency of messages, and presented from a voice of authority. Conclusion and Implication While parents expressed desires to be healthy, the home food environment presented substantial challenges. Multi-media supports such as workshops, flyers, and text messaging may be useful to facilitate the sharing of information to minimize the tensions between intentionality and reaching desired goals to be healthy. Some parents thought that information received through text messaging could be easily shared and would act as a voice of authority to support child behavior change. PMID- 29445981 TI - The Impact of Food Insecurity on the Home Emotional Environment Among Low-Income Mothers of Young Children. AB - Objectives Household stressors, such as food insecurity, contribute to the home emotional environment and negatively affect child development. Little research on this topic has been conducted among very young children. This study aimed to examine the relationship between food insecurity and the home emotional environment, as well the extent to which the relationship may be mediated by maternal symptoms of depression. Frequency of praise, affection, and discipline of young children by mothers were examined as markers of the home emotional environment. Methods Data were collected in a cross-sectional study of mothers of children under the age of five (N = 4231). Logistic regression was used to assess the relationship between level of food security and frequency of praise and discipline of children. Mediation analysis using the KHB method was conducted to test whether maternal mental health mediated the relationship between food insecurity and each outcome. Results Low and very low food security were significantly associated with higher odds of disciplining children with high frequency. Controlling for all covariates, frequency of praise was not significantly associated with level of household food insecurity. Differences in praise and discipline frequency were found by language of interview, maternal education, and employment. Conclusions for Practice Parent-child interactions, specifically related to discipline, are related to food insecurity. Further research should consider cultural patterns and mechanisms behind the relationship between food insecurity and the home environment. Household stressors begin affecting children at young ages, and early intervention is essential to prevent further negative sequelae as children grow older.

AB - Introduction This paper describes the care coordination training program and results of an evaluation from its pilot in seven states. Despite the importance of practice-based care coordination, only 42.3% of children with special health care needs (CYSHCN) met all needed components of care coordination as defined by the Maternal Child Health Bureau. Recognizing that children with medically complex conditions often have lower rates of achieving care coordination within a medical home, the Region 4 Midwest Genetics Collaborative worked with families to develop a training to empower families in care coordination. The Care Coordination: Empowering Families(CCEF) training provides families with the knowledge, tools, and resources to engage with health, education and family support systems. This article gives an overview of the training and comprehensive evaluation. Methods Participants were family caregivers of children with genetic conditions and other special health care needs recruited in one of seven pilot states. Evaluation data were collected from 190 participants prior to and immediately following the training. An additional follow-up assessment one full year post training was completed by 80 participants (a response rate of 42%). Results Families who attended the training report being the primary source of care coordination for their children and 83.7% see their role in their child's healthcare changing as a result of the training. The findings suggest that peer support and communication with providers increased as a result of the training over the course of the study. The data suggest that the training impacted how the family interacts with the child's doctor, including initiating conversations to prepare their child for transition to adult health care. Further, families report system-level improvements 1 year later compared to the pre-training assessment. Discussion CCEF training is a promising practice for facilitating medical home use among CYSHCN.

AB - PURPOSE: The purposes of this study were to investigate pulmonary vein cross sectional orifice area (PV-CSOA) using intracardiac echocardiography (ICE) and to determine its association with atrial fibrillation (AF) recurrence after radiofrequency catheter ablation (RFCA). METHODS: We studied 77 patients undergoing initial RFCA for AF (55 paroxysmal and 22 persistent AF patients, mean age 61 +/- 12 years, 59 men). The PV-CSOA was measured in each patient and expressed as an index divided by the body surface area-left superior (LSPV-CSOA), left inferior (LIPV-CSOA), right superior (RSPV-CSOA), and right inferior (RIPV CSOA). RESULTS: After a mean follow-up of 21 +/- 14 months, 61 patients maintained sinus rhythm (non-recurrence group) and AF recurred in 16 patients (recurrence group). The LSPV-CSOA index was significantly greater in the recurrence group compared with the non-recurrence group (146 +/- 41 vs. 126 +/- 30 mm2/m2, p = 0.04). A Cox regression multivariate analysis revealed that the LSPV-CSOA was the independent predictor of AF recurrence (HR 1.02, 95% CI 1.01 1.04, p = 0.01). The LSPV-CSOA cutoff value of 154 mm2/m2 predicts AF recurrence with 50% positive predictive value and 89% negative predictive value. CONCLUSIONS: The present study suggests that ICE can be used as an alternative imaging tools for assessing the PV-CSOA during RFCA and that the LSPV-CSOA index was a useful independent predictor of AF recurrence after RFCA. PMID- 29445984 TI - Impact of antibiotic prophylaxis on catheter-associated urinary tract infections during atrial fibrillation ablation. AB - PURPOSE: Urinary catheter placement is common during atrial fibrillation (AF) ablation when performed under general anesthesia. Whether patients undergoing AF ablation would benefit from prophylactic antibiotics is unknown. METHODS: Patients undergoing AF ablation in a single center from December 2011 until June 2016 were included. All patients received urinary catheters and general anesthesia. After June 2014, patients received antibiotic prophylaxis with a single dose of oral nitrofurantoin and a catheter insertion checklist performed prior to urinary catheter placement. The intervention group (group B) was compared to the pre-intervention group (group A) for development of the primary outcome. A multivariable logistic regression was performed to determine if any of the covariates were associated with catheter-associated urinary tract infection (CAUTI) development. RESULTS: There were 452 patients who underwent AF ablation during the analysis period (212 in group A and 240 in group B). The average patient age was 60 years (range 23-85) and 70% of the patients were male. Utilizing an intention to treat approach, there was a significantly lower incidence of CAUTI in the intervention group compared to controls (4.7 vs. 0.83%; OR 0.18, p = 0.029). There were no significant differences between the groups with respect to urinary tract infection risk factors or catheter duration. CONCLUSION: An intervention consisting of a single dose of nitrofurantoin in addition to performance of a catheter insertion checklist prior to urinary catheter insertion decreased CAUTI by 80% in patients undergoing AF ablation. Such interventions may be beneficial to reduce CAUTI in this group of patients. PMID- 29445985 TI - Acute pericarditis following second-generation cryoballoon ablation for atrial fibrillation. AB - PURPOSE: Acute pericarditis is a minor complication following atrial fibrillation (AF) ablation procedures. The aim of the study was to evaluate the incidence and clinical aspects of pericarditis following cryoballoon (CB) ablation of AF investigating a possible association with procedural characteristics and a possible relationship with post-ablation recurrences. METHODS: Four hundred fifty consecutive patients (male 73%, age 59.9 +/- 11.2 years) with drug-resistant paroxysmal AF who underwent CB ablation as index procedure were enrolled. Exclusion criteria were any contraindication for the procedure including the presence of intracavitary thrombus and uncontrolled heart failure and contraindications to general anesthesia. RESULTS: Acute pericarditis following CB ablation occurred in 18 patients (4%) of our study population. Pericardial effusion occurred in 14 patients (78%) and was mild/moderate. The total number of cryoapplications and the total freeze duration were significantly higher in patients with pericarditis compared with those without (respectively, p = 0.0006 and p = 0.01). Specifically, the number of applications and freeze duration in right inferior pulmonary vein were found significantly higher in patients with pericarditis (p = 0.007). The recurrence rate did not significantly differ between the two study groups (respectively, 16.7 vs 18.1%; p = 0.9). CONCLUSIONS: The incidence of acute pericarditis following CB ablation in our study population accounted for 4% and was associated with both total freezing time and number of cryoapplications. The clinical course was favorable in all these patients and the occurrence of acute pericarditis did not affect the outcome during the follow-up period. PMID- 29445986 TI - Pain threshold and temporomandibular function in systemic sclerosis: comparison with psoriatic arthritis. AB - The aim of the study was to evaluate whether a reduced pain threshold is associated with increased temporomandibular dysfunction in systemic sclerosis (SSc) compared to psoriatic arthritis (PsA) and healthy controls. Ninety subjects participated in the study (30 SSc, 30 PsA, and 30 healthy controls). The Helkimo index was used to evaluate temporomandibular dysfunction. Digital palpation was performed at the temporomandibular joint (TMJ) surface and at the superficial masseter muscle (SMM) and pain intensity was recorded on a visual analog scale (VAS), while pain pressure threshold (PPT) was measured at the same sites through a pressure algometer. PPT scores were lower in SSc patients compared to PsA patients and controls. In addition, the average Helkimo index score, measuring the degree of TMJ dysfunction, was higher in SSc compared to PsA and controls. A significant inverse correlation was observed between every PPT score, and both Helkimo index and VAS palpation in SSc and PsA. Both the range of motion and all the other pain-related subdomains of the Helkimo index score (pain on movement, pain palpation TMJ and pain palpation muscle) were significantly worse in SSc compared to PsA, while no significant differences were observed in the TMJ function subdomain. In SSc patients, the skin score was directly associated with the range of motion subdomain of the Helkimo index. Our results confirm that TMJ function is impaired in SSc; further longitudinal studies are needed to assess the role of pain threshold in the assessment of limitations in TMJ function and to identify an objective marker of therapeutic response. PMID- 29445987 TI - The complete genome sequence of CrRV-Ch01, a new member of the family Rhabdoviridae in the parasitic copepod Caligus rogercresseyi present on farmed Atlantic salmon (Salmo salar) in Chile. AB - We have determined the complete genome sequence of a new rhabdovirus, tentatively named Caligus rogercresseyi rhabdovirus Ch01 (CrRV-Ch01), which was found in the parasite Caligus rogercresseyi, present on farmed Atlantic salmon (Salmo salar) in Chile. The genome encodes the five canonical rhabdovirus proteins in addition to an unknown protein, in the order N-P-M-U (unknown)-G-L. Phylogenetic analysis showed that the virus clusters with two rhabdoviruses (Lepeophtheirus salmonis rhabdovirus No9 and Lepeophtheirus salmonis rhabdovirus No127) obtained from another parasitic caligid, Lepeophtheirus salmonis, present on farmed Atlantic salmon on the west coast of Norway. PMID- 29445988 TI - Viral shedding and clinical status of feline-norovirus-infected cats after reinfection with the same strain. AB - Norovirus (NoV) infection is the most common cause of acute gastroenteritis in humans of all ages worldwide. When cats are experimentally infected with feline norovirus (FNoV), they develop symptoms of acute gastroenteritis. Therefore, FNoV infection may serve as an animal model for the disease caused by human norovirus infection. In this study, we examined whether FNoV of cats infected with genogroup GVI are protected from reinfection with the same strain. The blood anti FNoV IgG level was inversely correlated with the viral load in stool samples and the clinical score of FNoV-infected cats, but complete prevention of reinfection was not observed. These findings were similar to the results of a reinfection experiment with NoV in human volunteers. PMID- 29445989 TI - Relevance of sleep quality on caregiver burden in Parkinson's disease. AB - Parkinson's disease (PD) is a neurodegenerative disorder which affects the quality of life of patient and their family. Sleep disorders appear in 80-90% of PD patients and have a great impact on the PD well-being. We examined the relationship of patients' sleep quality and depression on burden, mood, quality of life, and quality of sleep of their caregivers. A multicenter, regional (Veneto), observational, cross-sectional study that included 55 patient-caregiver pairs was conducted. Patients were assessed using Parkinson's Disease Sleep Scale (PDSS) and Epworth Sleepiness Scale (ESS) for sleep disorders, Beck Depression Inventory (BDI) as a measure of depression, and Parkinson's Disease Questionnaire (PDQ-39) as a measure of quality of life. Caregivers were evaluated by the Caregiver Burden Inventory (CBI) a measure of burden, BDI, SF-36 Health Survey as measures of HRQoL, and Medical Outcomes Study-Sleep Scale (MOS-SS) for quality of sleep. CBI, HRQoL, MOS-SS, and BDI scores displayed no association with patients' age, cognition (Mini Mental State Examination (MMSE) and Frontal Assessment Battery (FAB)), disease duration, and Hoehn and Yahr (H&Y), and UPDRS III scales whereas were significantly correlated with patients' quality of sleep, depression, and quality life. CBI and HRQoL were also associated respectively with patients' ESS and L-dopa daily dose. This study underscores the presence of a significant relationship between patient and caregiver quality of life. Interestingly, sleep quality and depression rather than motor disability best predicted caregivers' well-being. PMID- 29445990 TI - Time-dependent LXR/RXR pathway modulation characterizes capillary remodeling in inflammatory corneal neovascularization. AB - Inflammation in the normally immune-privileged cornea can initiate a pathologic angiogenic response causing vision-threatening corneal neovascularization. Inflammatory pathways, however, are numerous, complex and are activated in a time dependent manner. Effective resolution of inflammation and associated angiogenesis in the cornea requires knowledge of these pathways and their time dependence, which has, to date, remained largely unexplored. Here, using a model of endogenous resolution of inflammation-induced corneal angiogenesis, we investigate the time dependence of inflammatory genes in effecting capillary regression and the return of corneal transparency. Endogenous capillary regression was characterized by a progressive thinning and remodeling of angiogenic capillaries and inflammatory cell retreat in vivo in the rat cornea. By whole-genome longitudinal microarray analysis, early suppression of VEGF ligand-receptor signaling and inflammatory pathways preceded an unexpected later phase preferential activation of LXR/RXR, PPARalpha/RXRalpha and STAT3 canonical pathways, with a concurrent attenuation of LPS/IL-1 inhibition of RXR function and Wnt/beta-catenin signaling pathways. Potent downstream inflammatory cytokines such as Cxcl5, IL-1beta, IL-6 and Ccl2 were concomitantly downregulated during the remodeling phase. Upstream regulators of the inflammatory pathways included Socs3, Sparc and ApoE. A complex and coordinated time-dependent interplay between pro- and anti-inflammatory signaling pathways highlights a potential anti inflammatory role of LXR/RXR, PPARalpha/RXRalpha and STAT3 signaling pathways in resolving inflammatory corneal angiogenesis. PMID- 29445991 TI - Rainbow trout (Oncorhynchus mykiss) anesthesia with myrcene: efficacy and physiological responses in comparison with eugenol. AB - The aim of the present study was to investigate anesthetic efficacy of myrcene in rainbow trout (Oncorhynchus mykiss) along with the fish biochemical response to anesthesia in comparison with eugenol. In the first experiment, 240 fish were stocked in 12 tanks and acclimatized to experimental conditions for 2 weeks. Then, the fish of each tank were subjected to one concentration of either eugenol (12, 20, 30, 50, 80, and 130 MUL/L) or myrcene (100, 150, 200, 300, 400, and 500 MUL/L) concentrations. Induction time of and recovery time from anesthesia were recorded for each fish separately. Using these results, desired concentrations to induce anesthesia within 60, 180, 300, and 600 s were determined, being 81, 30, 19, and 10 MUL/L eugenol and 531, 251, 177, and 111 MUL/L myrcene. In the second experiment, 96 fish were stocked in 8 tanks. Six fish were netted from each tank and exposed to the calculated eugenol or myrcene concentrations. Blood samples were taken after the fish reached anesthesia. The results showed that there was no significant difference in serum lactate, alanine transaminase, and alkaline phosphatase. Increase in the induction time of anesthesia resulted in increased serum glucose with no significant difference between the anesthetics. Increase in induction time of anesthesia led to increase in serum lactate dehydrogenase activity in the eugenol-anesthetized fish and aspartate transaminase activity in myrcene-anesthetized fish. In conclusion, myrcene is capable to anesthetize rainbow trout, but at higher concentrations compared to eugenol. In addition, biochemical analysis showed that increase in induction time of anesthesia leads to hyperglycemia and increase in AST and LDH activities depending on anesthetic type. PMID- 29445992 TI - The functional genomics laboratory: functional validation of genetic variants. AB - Currently, one of the main challenges in human molecular genetics is the interpretation of rare genetic variants of unknown clinical significance. A conclusive diagnosis is of importance for the patient to obtain certainty about the cause of the disease, for the clinician to be able to provide optimal care to the patient and to predict the disease course, and for the clinical geneticist for genetic counseling of the patient and family members. Conclusive evidence for pathogenicity of genetic variants is therefore crucial. This review gives an introduction to the problem of the interpretation of genetic variants of unknown clinical significance in view of the recent advances in genetic screening, and gives an overview of the possibilities for functional tests that can be performed to answer questions about the function of genes and the functional consequences of genetic variants ("functional genomics") in the field of inborn errors of metabolism (IEM), including several examples of functional genomics studies of mitochondrial disorders and several other IEM. PMID- 29445993 TI - Unintended Consequences of Evidence-Based Treatment Policy Reform: Is Implementation the Goal or the Strategy for Higher Quality Care? AB - This study examined patterns of evidence-based treatment (EBT) delivery following a county-wide EBT reform initiative. Data were gathered from 60 youth and their 21 providers, who were instructed to deliver therapy as they normally would under the EBT initiative. Results showed limited applicability of county-supported EBTs to this service sample, and that most youth did not receive traditional delivery of EBTs. Findings suggest that it may be unrealistic to expect providers to deliver EBTs with fidelity with all clients, and that EBT implementation may be best thought of as a strategy for improving mental health services rather than a goal. PMID- 29445994 TI - Estimation of Posturographic Trajectory Using k-Nearest Neighbors Classifier in Patients with Rheumatoid Arthritis and Osteoarthritis. AB - Rheumatoid arthritis (RA) and osteoarthritis (OA) are common rheumatic diseases and account for a significant percentage of disability. Posturography is a method that assesses postural stability and quantitatively evaluates postural sways. The objective of this study was to estimate posturographic trajectories applying pattern recognition algorithms. To this end, k-nearest neighbors (k-NN) classifier was used to differentiate between healthy subjects and patients with OA and RA. The following parameters of trajectories were computed: radius of sways, developed area, total length, and two directional components of sways: length of left-right and forward-backward motions. Posturographic tests were applied with eyes open and closed, and with biofeedback control. We found that in RA, the radius of sways, the trajectory area, and the biofeedback coordination were related to the patients' condition. The trajectory dynamics in OA patients were smaller compared to those in RA patients. The smallest misclassification errors were observed after feature selection in the biofeedback test compared with the eyes open and closed tests. We conclude that the estimation of posturographic trajectory with k-NN classifier could be helpful in monitoring the condition of RA patients. PMID- 29445995 TI - Long-Term Exposure to Ambient Air Pollution in Childhood-Adolescence and Lung Function in Adulthood. AB - The aim of the study was to evaluate the effect of air pollution in the dwelling place during childhood-adolescence on respiratory function in early adulthood. The study was conducted in 220 female and 160 male university undergraduates in the cities of Cracow and Wroclaw in Poland and consisted of spirometry to assess lung function. The subjects' exposure to pollution during childhood-adolescence was assessed from the data acquired by the Polish Chief Inspectorate for Environmental Protection. We found differences in all spirometry variables depending on benz[a]piren exposure, in FVC% and FEV1/%FVC depending on PM2.5 content, and in FVC% depending on NO2 content. Statistically significant differences in spirometry variables were also found in relation to the degree of urbanization of the place of living during the early life period in question. The higher the urbanization, the higher is FEV1% and FCV%, and the lower FEV1/%FVC. Additionally, undergraduates of Cracow University had worse lung function compared to those of Wroclaw University. In conclusion, air pollution in the dwelling place during childhood-adolescence has an impact on lung function in early adulthood, independently of the current exposure to pollutants. PMID- 29445996 TI - Baker's Asthma: Is the Ratio of Rye Flour-Specific IgE to Total IgE More Suitable to Predict the Outcome of Challenge Test Than Specific IgE Alone. AB - Usually the diagnosis of baker's asthma is based on specific inhalation challenge with flours. To a certain extent the concentration of specific IgE to flour predicts the outcome of challenge test in bakers. The aim of this study was to evaluate whether the ratio of specific IgE (sIgE) to total IgE (tIgE) improves challenge test prediction in comparison to sIgE alone. Ninety-five bakers with work-related respiratory symptoms were challenged with rye flour. Total IgE, sIgE, and the sIgE/tIgE ratio were determined. Receiver operator characteristic (ROC) plots including the area under the curve (AUC) were calculated using the challenge test as gold-standard. Total IgE and sIgE concentrations, and their ratio were significantly higher in bakers with a positive challenge test than in those with a negative one (p < 0.0001, p < 0.0001, and p = 0.023, respectively). In ROC analysis, AUC was 0.83 for sIgE alone, 0.79 for tIgE, and 0.64 for the ratio. At optimal cut-offs, tIgE, sIgE, and the ratio reached a positive predicted value (PPV) of 95%, 84% and 77%, respectively. In conclusion, calculating the ratio of rye flour-sIgE to tIgE failed to improve the challenge test prediction in our study group. PMID- 29445997 TI - Human Papillomavirus-Related Multiphenotypic Sinonasal Carcinoma: A Case Report Documenting the Potential for Very Late Tumor Recurrence. AB - Human papillomavirus (HPV)-related multiphenotypic sinonasal carcinoma is a peculiar sinonasal tract tumor that demonstrates features of both a surface derived and salivary gland carcinoma. Implicit in its name, this tumor has a consistent association with high-risk HPV, particularly type 33. It was first described in 2013 under the designation of HPV-related carcinoma with adenoid cystic carcinoma-like features. However, since its initial description additional cases have emerged which demonstrate a wide morphologic spectrum and relatively indolent clinical behavior. Herein we report our experience with a case of HPV related multiphenotypic sinonasal carcinoma that was initially classified as adenoid cystic carcinoma in the 1980s. The patient recurred after a 30-year disease free interval. RNA in situ hybridization confirmed the presence of high risk HPV in both her recurrence and her initial tumor in the 1980s, which allowed for reclassification as HPV-related multiphenotypic sinonasal carcinoma. Our case adds to the literature of this relatively newly described entity and supports the indolent clinical behavior of this neoplasm but also demonstrates a potential for very late local recurrence.

PMID- 29445999 TI - The S190R mutation in the hemagglutinin protein of pandemic H1N1 2009 influenza virus increased its pathogenicity in mice. AB - Human influenza viruses preferentially bind to sialic acid-alpha2,6-galactose (SAalpha2,6Gal) receptors, which are predominant in human upper respiratory epithelia, whereas avian influenza viruses preferentially bind to SAalpha2,3Gal receptors. However, variants with amino acid substitutions around the receptor binding sites of the hemagglutinin (HA) protein can be selected after several passages of human influenza viruses from patients' respiratory samples in the allantoic cavities of embryonated chicken eggs. In this study, we detected an egg adapted HA S190R mutation in the pandemic H1N1 virus 2009 (pdmH1N1), and evaluated the effects of this mutation on receptor binding affinity and pathogenicity in mice. Our results revealed that residue 190 is located within the pocket structure of the receptor binding site. The single mutation to arginine at position 190 slightly increased the binding affinity of the virus to the avian receptor and decreased its binding to the long human alpha2,6-linked sialic acid receptor. Our study demonstrated that the S190R mutation resulted in earlier death and higher weight loss in mice compared with the wild-type virus. Higher viral titers at 1 dpi (days post infection) and diffuse damage at 4 dpi were observed in the lung tissues of mice infected with the mutant virus.

PMID- 29446001 TI - Canakinumab treatment in renal transplant recipients with familial Mediterranean fever. AB - Colchicine is the first-line treatment for familial Mediterranean fever (FMF), preventing both inflammatory attacks as well as the development of amyloidosis in the majority of the patients. However approximately 5-10% of patients are colchicine resistant/intolerant. Side effects of colchicine are more prominent in renal transplant recipients due to interaction with immunosuppressive drugs. Anti interleukin (IL)-1 drugs (anakinra, canakinumab and rilonacept) have emerged as the most promising drugs in the treatment of colchicine-resistant and/or intolerant FMF. There are no existing reports in the literature on canakinumab use in renal transplant recipients with FMF. We report here the efficacy and safety of canakinumab in three renal transplant recipients who achieved a complete clinical response with elimination of attacks and normalization of serum C-reactive protein (CRP) levels without significant side effects. This highlights the advantage of use of this drug in this setting, which has a better tolerability compared to anakinra. PMID- 29446002 TI - Genomic characterization of the first oral avian papillomavirus in a colony of breeding canaries (Serinus canaria). AB - Papillomaviruses are non-enveloped, DNA viruses that infect skin and mucosa of a wide variety of vertebrates, causing neoplasias or simply persisting asymptomatically. Avian papillomaviruses, with six fully sequenced genomes, are the second most studied group after mammalian papillomaviruses. In this study, we describe the first oral avian papillomavirus, detected in the tongue of a dead Yorkshire canary (Serinus canaria) and in oral swabs of the same bird and other two live canaries from an aviary in Madrid, Spain. Its genome is 8,071 bp and presents the canonical papillomavirus architecture with six early (E6, E7, E1, E9, E2, E4) and two late open reading frames (L1 and L2) and a long control region between L1 and E6. This new avian papillomavirus L1 gene shares a 64% pairwise identity with FcPV1 L1, so it has been classified as a new species (ScPV1) within the Ethapapillomavirus genus. Although the canary died after showing breathing problems, there is no evidence that the papillomavirus caused those symptoms so it could be part of the oral microbiota of the birds. Hence, future investigations are needed to evaluate the clinical relevance of the virus.

AB - This paper examines the difference in patient specific dosimetry using three different detectors of varying active volume, density and composition, for quality assurance of stereotactic treatments. A PTW 60017 unshielded electron diode, an Exradin W1 scintillator, and a PTW 31014 PinPoint small volume ionisation chamber were setup in a Lucy 3D QA phantom, and were positioned at the isocentre of an Elekta Axesse, with beam modulator collimator, using Exactrac and a HexaPODTM couch. Dose measurements were acquired for 43 stereotactic arcs, and compared to BrainLAB iPlan version 3.0.0 treatment planning system (TPS) calculations using a pencil beam algorithm. It was found that for arcs with field sizes [Formula: see text] mm, the properties of a detector have minimal impact on the measured doses, with all three detectors agreeing with the TPS (to within 5%). However, for field sizes [Formula: see text] mm, only the scintillator was found to yield results to within 5% of the TPS. The dose discrepancies were found to increase with decreasing field size. It is recommended that for field sizes [Formula: see text] mm, a water equivalent dosimeter like the Exradin W1 scintillator be used in order to minimise detector composition perturbations in the measured doses. PMID- 29446005 TI - Assessing Oral Cancer Awareness Among Dental Students. AB - The aim of this study was to assess oral cancer awareness among undergraduate dental students in Marmara University Faculty of Dentistry. A validated questionnaire which tested oral cancer awareness was given to third- and fifth year students of the dental faculty of Marmara University. A total of 198 students participated in this survey. Knowledge of oral cancer risk factors and diagnosis procedures, dentistry student's attitude towards oral cancers, management practice regarding oral cancer, and oral cancer information sources were assessed using 25 questions. The data were analyzed with IBM SPSS Statistics 22.0 program. Among 198 participant dentistry students, there were 99 (50%) third grade and 99 (50%) fifth-grade students. The largest number of the third- and last-grade students identified tobacco (98%) and alcohol usage (87.4%), prior oral cancer lesions (94.9%), viral infections (91.9%), UV exposure (94.4%), betel quid chewing (84.8%), older age (62.1%), and low consumption of fruit and vegetables (85.4%). Both groups showed higher scores in indicating squamous cell carcinoma as the most common form of oral cancer (p < 0.05); yet, third-grade students performed significantly higher scores in indicating erythroplakia and leukoplakia for most likely to be precancerous (p = 0.001; p < 0.05). This study highlighted the importance of improved educational methods for dentistry on oral cancer detection and prevention. PMID- 29446003 TI - Development of a 'ready-to-use' tool that includes preventability, for the assessment of adverse drug events in oncology. AB - Background Adverse drug events (ADEs) occur frequently in oncology and justify continuous assessment and monitoring. There are several methods for detecting them, but the trigger tool method seems the most appropriate. Although a generic tool exists, its use for ADEs in oncology has not been convincing. The development of a focused version is therefore necessary. Objective To provide an oncology-focused trigger tool that evaluates the prevalence, harm, and preventability in a standardised method for pragmatic use in ADE surveillance. Setting Hospitals with cancer care in France. Method The tool has been constructed in two steps: (1) constitution of an oncology-centred list of ADEs; 30 pharmacists/practitioners in cancer care from nine hospitals selected a list of ADEs using a method of agreement adapted from the RAND/UCLA Appropriateness Method; and (2) construction of three standardised dimensions for the characterisation of each ADE (including causality, severity, and preventability). Main outcome measure The main outcome measure was validation of the tool, including preventability criteria. Results The tool is composed of a final list of 15 ADEs. For each ADE, a 'reviewer form' has been designed and validated by the panel. It comprises (1) the trigger(s), (2) flowcharts to guide the reviewer, (3) criteria for grading harm, and (4) a standardised assessment of preventability with 6-14 closed sentences for each ADE in terms of therapeutic management and/or prevention of side-effects. Conclusion A complete 'ready-to use' tool for ADE monitoring in oncology has been developed that allows the assessment of three standardised dimensions. PMID- 29446006 TI - Exploring the chemical space of peptides for drug discovery: a focus on linear and cyclic penta-peptides. AB - Peptide and peptide-like structures are regaining attention in drug discovery. Previous studies suggest that bioactive peptides have diverse structures and may have physicochemical properties attractive to become hit and lead compounds. However, chemoinformatic studies that characterize such diversity are limited. Herein, we report the physicochemical property profile and chemical space of four synthetic linear and cyclic combinatorial peptide libraries. As a case study, the analysis was focused on penta-peptides. The chemical space of the peptide and N methylated peptides libraries was compared to compound data sets of pharmaceutical relevance. Results indicated that there is a major overlap in the chemical space of N-methylated cyclic peptides with inhibitors of protein-protein interactions and macrocyclic natural products available for screening. Also, there is an overlap between the chemical space of the synthetic peptides with peptides approved for clinical use (or in clinical trials), and to other approved drugs that are outside the traditional chemical space.

AB - BACKGROUND: To retard progression of chronic kidney disease (CKD) and reduce end stage kidney disease, it is important to detect acute kidney function worsening on CKD (AW-CKD) immediately and bring back their kidney functions to baselines by appropriate treatment. However, in general outpatient practice, it is difficult to detect the change in the slope of estimated glomerular filtration rate (eGFR). METHODS: We made automatic calculation system for the rate of eGFR decline (DeltaeGFR), and retrospectively observed the situation of AW-CKD among outpatients, who had visited all clinical departments of Steel Memorial Hirohata Hospital between May and August 2016, using the system. The patients with DeltaeGFR over 20 mL/min/1.73 m2/year were classified into "Detected cases", who were immediately detected AW-CKD by the attending physicians, and "Not detected cases". For each stratum of DeltaeGFR, subsequent eGFR recovery rates between two groups were compared. RESULTS: Among 6719 outpatients, 865 had CKD stages G3-5 and of which 196 had DeltaeGFR over 20 mL/min/1.73 m2/year. We revealed that, in cases of DeltaeGFR over 30 mL/min/1.73 m2/year, eGFR recovery rates in "Detected cases" were significantly higher than those in "Not detected cases" (103.2 vs 43.9%, p < 0.001). There were no differences in the clinical backgrounds except kidney function between two groups. CONCLUSION: In general outpatient practice, a substantial number of AW-CKD was latent. It is expected to improve kidney prognoses of outpatients having CKD through immediately detecting the patients, whose DeltaeGFR over 30 mL/min/1.73 m2/year using the system and alerting the attending physicians on the electronic medical record.

AB - Genetic engineering approaches offer an alternative method to the conventional breeding of Citrus sp. 'W. Murcott' mandarin (a hybrid of 'Murcott' and an unknown pollen parent) is one of the most commercially important cultivars grown in many regions around the world. Transformation of 'W. Murcott' mandarin was achieved by direct DNA uptake using a protoplast transformation system. DNA construct (pAO3), encoding Green Fluorescent Protein (GFP) and the cDNA of Xa21, a Xanthomonas resistance gene from rice, was used to transform protoplasts of 'W. Murcott' mandarin. Following citrus protoplast culture and regeneration, transformed micro calli were microscopically designated via GFP expression, physically isolated from non-transformed tissue, and cultured on somatic embryogenesis induction medium. More than 150 transgenic embryos were recovered and from them, ten transgenic lines were regenerated and cultured on rooting medium for shoot elongation. Transgenic shoots were micrografted and established in the greenhouse with 3-5 replicates per line. The insertion of Xa21 and GFP was confirmed by PCR and southern blot analysis. GFP expression was verified by fluorescence microscopy and western blot analysis revealed expression of Xa21 although it was variable among transgenic lines, as shown by RT-qPCR. Transgenic plants challenged with the citrus canker pathogen by syringe inoculation showed a reduction in lesion number and bacterial populations within lesions compared to non-transgenic control plants. Transgenic 'W. Murcott' mandarin lines with improved canker resistance via protoplast transformation from embryogenic callus with the Xa21 gene from rice are being evaluated under field conditions to validate the level of resistance. PMID- 29446009 TI - The ethics of separating conjoined twins: two arguments against. AB - I argue that the separation of conjoined twins in infancy or early childhood is unethical (rare exceptions aside). Cases may be divided into three types: both twins suffer from lethal abnormalities, only one twin has a lethal abnormality, or neither twin does. In the first kind of case, there is no reason to separate, since both twins will die regardless of treatment. In the third kind of case, I argue that separation at an early age is unethical because the twins are likely to achieve an irreplaceably good quality of life-the goods of conjoinment-that separation takes away. Evaluation of this possibility requires maturation past early childhood. Regarding the second type, I point out that with conceivable but unrecorded exceptions, these cases will consistently involve sacrifice separation. I present an argument that sacrifice separation is unethical, but in some cases a moral dilemma may exist in which separation and refraining from separation are both unethical. Perhaps in such cases a decision can be made on non-moral grounds; however, the possibility of such a decision serves not to mitigate but to underscore the fact that the separation is unethical. My conclusion, which applies to all three types of cases, is that it is unethical to separate conjoined twins before their developing personalities give some reliable indication as to whether they desire separation and whether they will achieve those goods of conjoinment. PMID- 29446010 TI - Phosphaturic mesenchymal tumors: what an endocrinologist should know. AB - Tumor-induced osteomalacia (TIO), also known as "oncogenic osteomalacia", is a rare cause of osteomalacia. TIO often has an insidious onset characterized clinically by progressive muscle weakness and bone pain with fractures. The hallmark biochemical finding is a persistent low serum phosphorus concentration due to renal phosphate wasting. The vast majority of cases of TIO result from production of the phosphaturic hormone fibroblast growth factor 23 (FGF23) by a histologically distinctive mesenchymal tumor, termed "phosphaturic mesenchymal tumor" (PMT). Circulating FGF23 induces internalization of renal sodium/phosphate co-transporters resulting in reduced proximal tubular phosphate reabsorption. FGF23 also inhibits production of 1alpha,25-dihydroxyvitamin D which is inappropriately low or normal in the context of hypophosphatemia. Diagnosis is often delayed owing to the rarity of the condition and an underappreciation for the role of phosphorus as a cause for the constellation of symptoms. Primary treatment for TIO is identification of the offending tumor and surgical removal. However, these tumors are notoriously difficult to find, precluding the opportunity for a curative surgery in many. In such cases, phosphate and calcitriol therapy is used to improve symptoms and heal the osteomalacia. Recently, molecular genetic studies have shown recurrent genetic events in PMT, including the novel fusions FN1-FGFR1 and less commonly FN1-FGF1. These fusion events are hypothesized to result in autocrine/paracrine signaling loops within the tumor, spurring tumorigenesis. This review will cover the clinical features, imaging characteristics, pathologic features, molecular genetic aspects, and therapy of PMT, with a brief discussion of other neoplasms that may cause TIO. PMID- 29446011 TI - Continuously sustained elimination of iodine deficiency: a quarter of a century success in the Islamic Republic of Iran. AB - BACKGROUND: Iodine deficiency and related disorders were very common in Iran prior to 1996, when universal salt iodization (USI) was implemented and in 2000 Iran was declared iodine deficiency disorders (IDD) free. The aim of this study was to evaluate the adequacy of iodine intake by Iranian households in all 30 provinces of Iran, a quarter of a century after the intervention. METHODS: A total of 18,000 school-aged children (8-10 years with mean 8.7 +/- 1 year) were included in this study. Urine samples were collected from all children for measurement of urinary iodine excretion and 1800, 210 and 3000 salt samples were randomly collected from the family kitchen, production site of 73 salt factories and distribution circles of 30 provinces, respectively. RESULTS: The median urinary iodine concentration (UIC) of participants was 161 MUg/L. The proportion of children with UIC of, 20-49, 50-99 and >= 100 MUg/L were 10.3, 15.9 and 73.7%, respectively. The mean (+/- SD) and median salt iodine values were 28.2 (+/- 12.6) and 31.7 ppm, at the production site, and 31.5 (+/- 13.6) and 29.6 ppm at the distribution circles, respectively. About 80% of factory salts had more than 20 ppm iodine. 98% of households consumed iodized salt, 80% had appropriate salt storage, and 83% of the household salts contained >= 20 ppm. CONCLUSIONS: Based on the results of this study, Iranian populations are consuming adequate iodine. The well-maintained and monitored USI program has improved the dietary iodine intakes of the population, and the country has achieved all criteria of a well controlled IDD program. PMID- 29446013 TI - Chronic graft-specific cell-mediated immune response toward candidate xenogeneic biomaterial. AB - Despite rabbits becoming an increasingly popular animal model, a flow cytometry panel that combines T cell markers (CD3, CD4, CD8, CD25, FOXP3) with a method for monitoring proliferation is lacking in this species. It has been shown that the rabbit model can be used to identify xenoantigens within bovine pericardium (BP), a common biological heart valve replacement material; however, these methods rely on monitoring the humoral immune response. The development of a rabbit T cell proliferation assay has utility in monitoring graft-specific cell-mediated immune responses toward bovine pericardium. Isolation and culture conditions were optimized to avoid cell death, red blood cell contamination, and non-specific proliferation. Effect of cell culture and stimulation on distribution and intensity of T cell markers was analyzed and compared between cells isolated from naive and BP-immunized rabbits. Submaximal levels (0.25 MUg/mL) of concavalin A were used to stimulate proliferation toward BP extract, with resultant proliferation compared between naive and BP-immunized rabbits. Density stratification followed by ammonium potassium chloride (ACK) lysis yielded the greatest number of viable peripheral blood mononuclear cells with the least amount of erythrocyte contamination. Flat-bottomed plates were necessary to reduce non-specific proliferation in culture. T cells responded appropriately to maximal mitogenic stimulation (5 MUg/mL concavalin A). Interestingly, immunization increased the intensity of FOXP3 in T regulatory cells compared to cells from naive animals. With addition of submaximal levels of concavalin A, T cells from immunized rabbits proliferated in response to BP protein extract, while cells from naive rabbits did not. In immunized rabbits, not only did more CD4+ T cells proliferate in response to BP re-stimulation, but the intensity of CD25 was increased indicating cell activation. This research provides a functional cell-mediated screening assay for assessment of BP-based biomaterials in rabbits, overcoming the limitations of previous humoral immune system-based assessments of biomaterial antigenicity in this important experimental animal species.

AB - Aim To determine whether breast cancer survivors (BCS) at work following the diagnosis and/or treatment of breast cancer, in a rapidly developing country such as China experience similar to return to work challenges as reported in nations with established return to work (RTW) policy and procedures for employees with cancer. Methods Semi-structured interviews were conducted with 16 BCS who returned to work following diagnosis and/or primary cancer treatment. An Interpretative Phenomenological Analysis was used to investigate responses. Results Three recurring themes emerged: (1) challenges at work related to residual effects of diagnosis and/or primary treatment; (2) positive and negative responses from employers and/or supervisors; and (3) positive and negative responses from co-workers/colleagues. Although several participants experienced a high level of workplace support, there was a subgroup that did report challenges related to symptom burden, cognitive limitations, and both positive and negative responses by employers and co-workers were reported. Conclusions Findings indicate similar challenges in BCS who RTW during and/or following cancer treatment in both rapidly developing and developed nations. Results suggest that regardless of the existence of workplace policies and practices related to RTW for workers with a history of cancer, a subgroup of BCS experience similar challenges when returning to work. These findings highlight the international nature of RTW challenges and suggest the need for more global efforts to develop and evaluate workplace interventions to assist with these similarities. PMID- 29446012 TI - A meta-analysis of the effects of antidepressants on cognitive functioning in depressed and non-depressed samples. AB - A thorough understanding of the cognitive effects of antidepressant medications is essential given their frequency of use. This meta-analysis was conducted to investigate whether antidepressants differentially affect the various domains of cognitive functioning for depressed and non-depressed participants. An electronic search of PsycInfo, Medline and Google Scholar was conducted for all journal articles published between January 1998 and January 2017. Thirty-three studies were included enabling calculation of Hedges' g using a random effects model for the cognitive domains of divided attention, executive function, expressive language, immediate memory, perceptual motor skills, processing speed, recent memory, sustained attention, visuospatial-constructional skills and working memory. Results revealed that overall, antidepressants have a modest, positive effect on divided attention, executive function, immediate memory, processing speed, recent memory and sustained attention for depressed participants. Selective serotonin reuptake inhibitors (SSRI's) were found to have the greatest positive effect on cognition for depressed participants, as compared to the other classes of antidepressants analysed. Antidepressants did not significantly affect cognitive function in non-depressed participants. PMID- 29446016 TI - Removal of organochlorine pesticides from lindane production wastes by electrochemical oxidation. AB - This study is focused on the effective removal of recalcitrant pollutants hexaclorocyclohexanes (HCHs, isomers alpha, beta, gamma, and delta) and chlorobenzenes (CBs) present in a real groundwater coming from a landfill of an old lindane factory. Groundwater is characterized by a total organic carbon (TOC) content of 9 mg L-1, pH0 = 7, conductivity = 3.7 mS cm-1, high salt concentration (SO42-, HCO3-, Cl-), and ferrous iron in solution. The experiments were performed using a BDD anode and a carbon felt (CF) cathode at the natural groundwater pH and without addition of supporting electrolyte. The complete depletion of the four HCH isomers and a mineralization degree of 90% were reached at 4-h electrolysis with a current intensity of 400 mA, the residual TOC (0.8 mg L-1) corresponding mainly to formic acid. A parallel series reaction pathway was proposed: HCHs and CBs are transformed into chlorinated and hydroxylated intermediates that are rapidly oxidized to non-toxic carboxylic acids and/or mineralized, leading to a rapid decrease in solution pH. PMID- 29446017 TI - Transformation of heavy metal fractionation under changing environments: a case study of a drainage system in an e-waste dismantling community. AB - The change in environmental conditions during the transportation of contaminated soil and sediment was expected to affect the transformation of heavy metal fractionation. This study disclosed the serious contamination of copper (Cu), lead (Pb), and zinc (Zn) in the sewer sediment of an e-waste dismantling community in Thailand which may be caused by flushed contaminated soil and e waste fragments. Two environmental conditions were simulated to observe the transformation of heavy metal fractionation. The anoxic sewer condition was induced using high substrate and sulfate in a closed container. The aeration of anoxic contaminated sediment was applied to simulate the transformation to an oxidative environment. The BCR sequential extraction was applied for heavy metal fractionation in this study. The study results exhibited that when heavy metal contaminated soil was transferred into this induced anoxic condition, fractionation was redistributed based on the chemical change of system that tends to be associated into F3 (oxidizable fraction) > F2 (reducible fraction) > F1 (acid soluble/exchangeable fraction). Cu exhibited the outstanding capability association to F3. The iron sulfide was not observed as usual due to its lower capability than Cu, Pb, and Zn. When contaminated sediment was transported to a more oxidative environment, the heavy metals fractionation would be redistributed again among those new environment media. It is noteworthy that F3 of Cu was stable even in oxic conditions. F2 of Fe was not developed by this oxic condition, possibly because its dehydration process was limited. The redistribution under an oxic environment became F1 > F2 > F3 indicating their more available form. This transformation was imperative and should be taken into account in heavy metal contaminated site management and control. PMID- 29446015 TI - Synthetic polymeric biomaterials for wound healing: a review. AB - Wounds are of a variety of types and each category has its own distinctive healing requirements. This realization has spurred the development of a myriad of wound dressings, each with specific characteristics. It is unrealistic to expect a singular dressing to embrace all characteristics that would fulfill generic needs for wound healing. However, each dressing may approach the ideal requirements by deviating from the 'one size fits all approach', if it conforms strictly to the specifications of the wound and the patient. Indeed, a functional wound dressing should achieve healing of the wound with minimal time and cost expenditures. This article offers an insight into several different types of polymeric materials clinically used in wound dressings and the events taking place at cellular level, which aid the process of healing, while the biomaterial dressing interacts with the body tissue. Hence, the significance of using synthetic polymer films, foam dressings, hydrocolloids, alginate dressings, and hydrogels has been reviewed, and the properties of these materials that conform to wound-healing requirements have been explored. A special section on bioactive dressings and bioengineered skin substitutes that play an active part in healing process has been re-examined in this work. PMID- 29446018 TI - Green synthesis of silver nanoparticles using Piper nigrum: tissue-specific bioaccumulation, histopathology, and oxidative stress responses in Indian major carp Labeo rohita. AB - The aim of the present investigation is to assess the sublethal toxicity of biologically synthesized silver nanoparticles (Ag NPs) in Indian major carp Labeo rohita. Ag NPs used in the study were synthesized by using AgNO3 with aqueous leaf extract of Piper nigrum. Median lethal concentration (LC50) of synthesized Ag NPs was determined for 96 h (25 MUg/L); 2.5 MUg/L (1/10th LC50) and 5 MUg/L (1/5th LC50) were taken as sublethal concentrations to evaluate the toxicity for 35 days. The results of the TEM, SEM, and EDX analyses revealed that Ag NPs were considerably accumulated in the gill, liver, and kidney of fish at both concentrations (2.5 and 5 MUg/L). Consequently, the activity of the antioxidant enzymes, SOD and CAT, was significantly (P < 0.05) decreased in the gill, liver, and kidney when compared to the control group during the study period. However, lipid peroxidase (LPO) activity in the gill, liver, and kidney was significantly (P < 0.05) increased, and the result concluded a possible sign of free radical induced oxidative stress in Ag NP-exposed fish than the sham-exposed individuals. The histopathological study also confirmed the alterations such as degeneration of lamella, lifting of lamellar epithelium, hepatic necrosis, pyknotic nuclei, increased intracellular space, and shrinkage of glomerulus elicited by Ag NPs in the gill, liver, and kidney of Labeo rohita with two different concentrations. The findings of the present study revealed that green synthesis of Ag NPs from Piper nigrum at sublethal concentrations leads to accumulation of Ag, oxidative stress, and histopathological alterations in the target organs of the fish, Labeo rohita. PMID- 29446019 TI - Evaluation of vulnerable PM2.5-exposure individuals: a repeated-measure study in an elderly population. AB - Numerous studies have shown that elderly people are susceptible to high-level particles with aerodynamic diameter <= 2.5 MUm (PM2.5) exposure. However, not all elderly people exposed to PM2.5 suffer from diseases. In this study, we aim to establish a method to predict the vulnerable PM2.5-exposure individuals among elderly population. Fourteen elderly people were recruited from May 8 to July 4, 2016, in Nanjing, China. Ten physiological indicators were repeatedly measured for 15 times. Liner mixed-effects model, principal component analysis (PCA), and PM2.5 lag score were used to estimate the effects of PM2.5 on blood pressure, pulse, and lung function. As a result, each quartile increase of ambient PM2.5 was significantly associated with increased pulse (P < 0.05 for lag0, 1, 4, 0-1, 0-2, 0-3, and 0-5 days), decreased blood pressure (P < 0.05 for lag4 and 0-3 days), and decreased lung function (P < 0.05 for lag0, 1, 0-1, and 0-2 days) among the 14 elderly people. In terms of pulse or lung function, three elderly people were considered as vulnerable PM2.5-exposure individuals. No vulnerable individual was found for blood pressure. Blood pressure, pulse, and lung function could be affected by high-level PM2.5 exposure in elderly people. This method for screening three elderly people may provide a new insight on identifying the vulnerable PM2.5-exposure individuals. PMID- 29446020 TI - Achieving an extraordinary high organic and hydraulic loadings with good performance via an alternative operation strategy in a multi-stage constructed wetland system. AB - In this study, a high organic loading rate of 58-146 g BOD5/m2 day with a hydraulic loading rate (HLR) of 1.63 m3/m2 day and retention time (RT) of 16 h was achieved to maximize the treatment capacity of a four-stage alum sludge-based constructed wetland (CW) system. An alternative operation strategy, i.e., the first stage anaerobic up-flow and the remaining stage tidal flow with effluent recirculation, was investigated to achieve the goal with good treatment performance of 82% COD, 91% BOD5, 92% SS, 94% NH4-N, and 82% TN removal. Two kinetic models, i.e., first-order model and Monod plus continuous stirred-tank reactor (CSTR) flow model, were employed for predicting the removal dynamics. The results showed that the tidal flow strategy enhances oxygen transport and diffusion, thus improving reduction of organics and NH4-N. Effluent recirculation could further increase elimination of organics by extending the interaction time and also benefit the denitrification process. In addition, denitrification could be further enhanced by anaerobic up-flow in the first stage.

AB - Herein, biochar derived from lotus seedpods, as an effective adsorbent, was prepared by pyrolysis method at 300 and 600 degrees C. The physicochemical characteristics and cadmium adsorption properties were studied systematically by batch adsorption experiments, FTIR, SEM-EDX, XRD, and XPS. Cd adsorption onto lotus seedpod-derived biochar was better fitted using Freundlich isotherm and pseudo-second-order model. Adsorption capacity of biochar produced at 300 and 600 degrees C was 31.69 and 51.18 mg g-1, respectively. The Cd adsorption capacity of biochar was related to its characteristics determined by pyrolysis temperature, including carbonization, surface area, surface morphology, and surface functional groups. Cd adsorption on lotus seedpod-derived biochar revealed that adsorption was controlled by multiple mechanisms including surface complexation, ion exchange, surface precipitation, and Cd-pi interaction. This study showed that lotus seedpod-derived biochar is an effective and environmentally friendly adsorbent for water treatment. PMID- 29446022 TI - Removal of MCs by Bi2O2CO3: adsorption and the potential of photocatalytic degradation. AB - Microcystins (MCs) is a kind of hepatotoxin, which is the secondary metabolite of cyanobacteria. Bi2O2CO3 (BOC) is a kind of cheap and nontoxic semiconductor material. BOC was synthetized by solvothermal method and then microcystin-LR (MC LR) and microcystin-RR (MC-RR) were removed by BOC, through adsorption and photocatalytic degradation. When the dosage of BOC is 6 g/L, the MC-LR and MC-RR in the natural water sample can be completely adsorbed in 30 min and then after 12 h irradiation, MC-LR and MC-RR were photocatalytically degraded by BOC. PMID- 29446023 TI - Comparing the adsorption mechanism of Cd by rice straw pristine and KOH-modified biochar. AB - Biochar was considered as an effective and novel sorbent for cadmium (Cd) adsorption from aqueous solution. In this study, the adsorption isotherm investigations were conducted to examine the effect of biochar produced via pyrolysis from rice straw on removing aqueous Cd before and after modification by 2 M KOH solution. Langmuir and Freundlich adsorption isotherms can preferably describe the adsorption process. Results showed that the highest adsorption capacity of pristine rice straw biochar was 12.17 mg g-1. The chemically modified rice straw biochar showed greater Cd adsorption capacity of 41.9 mg g-1, which was more than three times that of pristine biochar. Increase of surface area and changes of porous structure, especially the functional groups on the surface of modified biochar, were the major contributors to its more efficient adsorption of Cd. The possible mechanisms for Cd adsorption by biochar mainly involve (1) surface precipitation by forming insoluble Cd compounds in alkaline condition and (2) ion exchange for Cd with exchangeable cations in the biochar, such as calcium ions, which were confirmed by FTIR, XRD, SEM, and zeta potential determination.

AB - Bisphenol A (BPA) is a widely used environmental pollutant in the production of plastics but causes hepatotoxicity in mammals. In the present study, we studied the BPA-induced oxidative stress in rats and ameliorative potential of Adiantum capillus-veneris L. plant. It was concluded that the BPA can reduce the body and liver weight, increase in biochemical levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), total bilirubin, and disturb the normal hepatic physiology, histology, and metabolism. Additionally, liver histology shows hepatic necrosis, congestion, and vacuolization in exposed individuals. In contrast, simultaneous exposure of A. capillus-veneris and BPA showed declining trend in serum biomarker levels and normal histopathological structures. We conclude that the A. capillus-veneris plant is antioxidant in nature and can reduce the BPA-induced toxicity. These findings are very helpful to understand the BPA-induced hepatic toxicity and ameliorative potential of A. capillus veneris plant and are of great importance in risk assessment of xenobiotics. PMID- 29446026 TI - Potentially useful elements (Al, Fe, Ga, Ge, U) in coal gangue: a case study in Weibei coal mining area, Shaanxi Province, northwestern China. AB - Coal gangue has become one of the largest industrial solid waste in China, but it is also a kind of reserve resources. Representative coal gangue samples from different coal mines (mainly in Permo-Carboniferous and Jurassic) in Weibei area in Shaanxi Province are collected, and potentially useful elements (Al, Fe, Ga, Ge, U) in coal gangue are analyzed. The results show that the reserves of Al and Fe in Chinese coal gangue are 262 million tons and 196 million tons, respectively, based on the geometric mean values of Al2O3 (15.18%, weight percent) and Fe2O3 (6.24%, weight percent). Meanwhile, the crude reserves estimation of Ga, Ge, and U are 55,282, 6867, and 32,981 tons, respectively, based on the weighted mean contents of Ga, Ge, and U in coal gangue at 17.55, 2.18, and 10.47 mg/kg, respectively. Furthermore, Ga and Al contents in quite a large number of coal gangue mines exceed the cutoff value, which has a prospect of development and utilization from coal gangue. The policy implications from this study may include that (1) recycling of useful elements in Chinese coal gangue should be treated as an integral part of sustainable development with professional legislations and (2) establishing a basic database of coal gangue and authoritative system with relevant departments for solid waste management may effectively improve comprehensive utilization of coal gangue in the future.

AB - Sunflower (Helianthus annuus L.) is a major oilseed crop grown for its edible oil across the globe including Pakistan. In Pakistan, the production of edible oil is less than the required quantity; the situation is being worsened with the increasing population. Thus, there is dire need to grow those sunflower genotypes which perform better under a given set of agronomic practices. In this 2-year study, we compared four sunflower genotypes, viz., Armoni, Kundi, Sinji, and S 278 for their yield potential, oil contents, fatty acid composition, and profitability under three sowing methods, viz., bed sowing, line sowing, and ridge sowing and two tillage system, viz., plow till and minimum till. Among the sunflower genotypes, the genotype Armoni produced the highest plant height, number of leaves, head diameter, 1000-achene weight, and achene yield; the oil contents and oleic acid were the highest in genotype Sinji. Among the sowing methods, the highest number of leaves per plant, head diameter, number of achenes per head, achene yield, and oil contents were recorded in ridge sowing. Among the tillage systems, the highest head diameter 16. 2 cm, 1000-achene weight (57.2 g), achene yield (1.8 t ha-1), oil contents (35.2%), and oleic acid (15.2%) were recorded in minimum till sunflower. The highest net benefits and benefit to cost ratio were recorded in minimum till ridge sown Armoni genotype. In conclusion, the genotype Armoni should be grown on ridges to achieve the highest achene yield, oil contents, and net profitability. PMID- 29446027 TI - Review of the methods for determination of reactive oxygen species and suggestion for their application in advanced oxidation induced by dielectric barrier discharges. AB - Advanced oxidation processes (AOPs) particularly non-thermal plasmas based on electrical discharges have been widely investigated for water and wastewater treatment. Dielectric barrier discharges (DBDs) generate large amounts of selective and non-selective reactive oxygen species (ROS) such as ozone, hydrogen peroxide, atomic oxygen, superoxide molecular anions and hydroxyl radicals, having been proved to be efficient for water decontamination among various forms of electrical discharge systems. The detection and quantification methods of these oxygen species in non-thermal plasmas have been reviewed. However, their application in dielectric barrier discharge has not been well studied. It is therefore imperative to summarise the various detection and quantification methods for oxygen-based species determination in AOPs, aqueous systems and non thermal plasma processes. Thereafter, reviewed methods are suggested for the determination of ROS in DBD configurations to understand the consumption trend of these oxidants during treatment of water effluents and to evaluate the performance of the treatment reactor configuration towards the degradation of targeted pollutants. PMID- 29446029 TI - Using network to enhance the insights on correlation and pollution assessment of co-occurring metals in marine sediments, the East China Sea. AB - In this study, sediment samples were collected from 24 sites in the East China Sea (ECS) to investigate the distribution characteristics, co-occurrence correlations, and ecological risks of metals. In surface sediments, metals presented a homologous banding distribution pattern decreasing seaward with distance. With network analysis, it indicated metals in this area might directly derive from the coastal river inputs. According to geo-accumulation indexes (Igeo), Cd was classified as moderate pollution at 58% sites, far above other metals. In addition, the potential ecological risk index (RI) was clustered with the ecological risk (ER) of Cd, which was regarded as considerable or high-risk level for most coastal stations. Thus Cd pollution in the ESC sediment should be paid more attention. In sum, the visualization of statistical analyses combined with geochemical approaches could reveal the potential sources of contaminants and ecological risks, thus facilitate the pollution evaluation in marine sediments.

AB - Cystinosis is a rare autosomal recessive lysosomal transport disorder, characterized by the accumulation of the aminoacid cystine and progressive dysfunction of several organs. Kidneys are severely affected, and the most frequent form, infantile nephropathic cystinosis, presents with growth failure in infancy, renal Fanconi syndrome and end-stage renal disease by the first decade of life. We report of a girl with infantile nephropathic cystinosis that has reached adolescence without the need of renal replacement therapy and without extrarenal manifestations despite her delayed diagnosis and treatment initiation. The girl with this intermediate phenotype was found to have compound heterozygosity of one known (1015G > A) and one novel (587_588insA) mutation in CTNS gene. Our case points to the wide clinical presentation of infantile nephropathic cystinosis and suggest that long-term outcome is not always ominous as generally thought.

AB - Attention-deficit/hyperactivity disorder (ADHD) and generalized joint hypermobility (JH) are two separated conditions, assessed, and managed by different specialists without overlapping interests. Recently, some researchers highlighted an unexpected association between these two clinical entities. This happens in a scenario of increasing awareness on the protean detrimental effects that congenital anomalies of the connective tissue may have on human health and development. To review pertinent literature to identify possible connections between ADHD and GJH, special emphasis was put on musculoskeletal pain and syndromic presentations of GJH, particularly the hypermobile Ehlers-Danlos syndrome. A comprehensive search of scientific databases and references lists was conducted, encompassing publications based on qualitative and quantitative research. Impaired coordination and proprioception, fatigue, chronic pain, and dysautonomia are identified as potential bridges between ADHD and JH. Based on these findings, a map of the pathophysiological and psychopathological pathways connecting both conditions is proposed. Although ADHD and JH are traditionally separated human attributes, their association may testify for the dyadic nature of mind-body connections during critical periods of post-natal development. Such a mixed picture has potentially important consequences in terms of disability and deserves more clinical and research attention. PMID- 29446033 TI - Climate Change, Foodborne Pathogens and Illness in Higher-Income Countries. AB - PURPOSE OF REVIEW: We present a review of the likely consequences of climate change for foodborne pathogens and associated human illness in higher-income countries. RECENT FINDINGS: The relationships between climate and food are complex and hence the impacts of climate change uncertain. This makes it difficult to know which foodborne pathogens will be most affected, what the specific effects will be, and on what timescales changes might occur. Hence, a focus upon current capacity and adaptation potential against foodborne pathogens is essential. We highlight a number of developments that may enhance preparedness for climate change. These include the following: Adoption of novel surveillance methods, such as syndromic methods, to speed up detection and increase the fidelity of intervention in foodborne outbreaks Genotype-based approaches to surveillance of food pathogens to enhance spatiotemporal resolution in tracing and tracking of illness Ever increasing integration of plant, animal and human surveillance systems, One Health, to maximise potential for identifying threats Increased commitment to cross-border (global) information initiatives (including big data) Improved clarity regarding the governance of complex societal issues such as the conflict between food safety and food waste Strong user-centric (social) communications strategies to engage diverse stakeholder groups The impact of climate change upon foodborne pathogens and associated illness is uncertain. This emphasises the need to enhance current capacity and adaptation potential against foodborne illness. A range of developments are explored in this paper to enhance preparedness. PMID- 29446034 TI - Molecular genetic diversity of Gongylonema neoplasticum (Fibiger & Ditlevsen, 1914) (Spirurida: Gongylonematidae) from rodents in Southeast Asia. AB - More than a dozen Gongylonema spp. (Spirurida: Spiruroidea: Gongylonematidae) have been described from a variety of rodent hosts worldwide. Gongylonema neoplasticum (Fibiger & Ditlevsen, 1914), which dwells in the gastric mucosa of rats such as Rattus norvegicus (Berkenhout) and Rattus rattus (Linnaeus), is currently regarded as a cosmopolitan nematode in accordance with global dispersion of its definitive hosts beyond Asia. To facilitate the reliable specific differentiation of local rodent Gongylonema spp. from the cosmopolitan congener, the genetic characterisation of G. neoplasticum from Asian Rattus spp. in the original endemic area should be considered since the morphological identification of Gongylonema spp. is often difficult due to variations of critical phenotypical characters, e.g. spicule lengths and numbers of caudal papillae. In the present study, morphologically identified G. neoplasticum from 114 rats of seven species from Southeast Asia were selected from archived survey materials from almost 4,500 rodents: Thailand (58 rats), Cambodia (52 rats), Laos (three rats) and Philippines (one rat). In addition, several specimens from four rats in Indonesia were used in the study. Nucleotide sequences of the ribosomal RNA gene (rDNA) (5,649 bp) and the cytochrome c oxidase subunit 1 gene (cox1) (818 bp) were characterised. The rDNA showed little nucleotide variation, including the internal transcribed spacer (ITS) regions. The cox1 showed 24 haplotypes, with up to 15 (1.83%) nucleotide substitutions regardless of parasite origin. Considering that Rattus spp. have been shown to originate from the southern region of Asia and G. neoplasticum is their endogenous parasite, it is reasonable to propose that the present study covers a wide spectrum of the genetic diversity of G. neoplasticum, useful for both the molecular genetic speculation of the species and the molecular genetic differentiation of other local rodent Gongylonema spp. from the cosmopolitan congener.

AB - INTRODUCTION: There is increasing interest in social digital media (SDM) as a data source for pharmacovigilance activities; however, SDM is considered a low information content data source for safety data. Given that pharmacovigilance itself operates in a high-noise, lower-validity environment without objective 'gold standards' beyond process definitions, the introduction of large volumes of SDM into the pharmacovigilance workflow has the potential to exacerbate issues with limited manual resources to perform adverse event identification and processing. Recent advances in medical informatics have resulted in methods for developing programs which can assist human experts in the detection of valid individual case safety reports (ICSRs) within SDM. OBJECTIVE: In this study, we developed rule-based and machine learning (ML) models for classifying ICSRs from SDM and compared their performance with that of human pharmacovigilance experts. METHODS: We used a random sampling from a collection of 311,189 SDM posts that mentioned Roche products and brands in combination with common medical and scientific terms sourced from Twitter, Tumblr, Facebook, and a spectrum of news media blogs to develop and evaluate three iterations of an automated ICSR classifier. The ICSR classifier models consisted of sub-components to annotate the relevant ICSR elements and a component to make the final decision on the validity of the ICSR. Agreement with human pharmacovigilance experts was chosen as the preferred performance metric and was evaluated by calculating the Gwet AC1 statistic (gKappa). The best performing model was tested against the Roche global pharmacovigilance expert using a blind dataset and put through a time test of the full 311,189-post dataset. RESULTS: During this effort, the initial strict rule based approach to ICSR classification resulted in a model with an accuracy of 65% and a gKappa of 46%. Adding an ML-based adverse event annotator improved the accuracy to 74% and gKappa to 60%. This was further improved by the addition of an additional ML ICSR detector. On a blind test set of 2500 posts, the final model demonstrated a gKappa of 78% and an accuracy of 83%. In the time test, it took the final model 48 h to complete a task that would have taken an estimated 44,000 h for human experts to perform. CONCLUSION: The results of this study indicate that an effective and scalable solution to the challenge of ICSR detection in SDM includes a workflow using an automated ML classifier to identify likely ICSRs for further human SME review. PMID- 29446036 TI - Mindfulness Approaches and Weight Loss, Weight Maintenance, and Weight Regain. AB - PURPOSE OF REVIEW: There is an urgent need for effective weight management techniques, as more than one third of US adults are overweight or obese. Recommendations for weight loss include a combination of reducing caloric intake, increasing physical activity, and behavior modification. Behavior modification includes mindful eating or eating with awareness. The purpose of this review was to summarize the literature and examine the impact of mindful eating on weight management. RECENT FINDINGS: The practice of mindful eating has been applied to the reduction of food cravings, portion control, body mass index, and body weight. Past reviews evaluating the relationship between mindfulness and weight management did not focus on change in mindful eating as the primary outcome or mindful eating as a measured variable. This review demonstrates strong support for inclusion of mindful eating as a component of weight management programs and may provide substantial benefit to the treatment of overweight and obesity. PMID- 29446038 TI - Preoperative evaluation of the elderly surgical patient and anesthesia challenges in the XXI century. AB - Universally recognized goals of preoperative anesthesia assessment are the evaluation of patient's health status to define the entity of the surgical risk, and the anticipation of possible complications while optimizing and planning preventive strategies. Data obtained by Comprehensive Geriatric Assessment (CGA) and frailty evaluation are of extreme usefulness in surgical risk evaluation in older patients and in the decision about surgery. It is from the team-based discussion of such results that the most appropriate treatment can be individuated, surgery invasiveness and duration critically analyzed and if needed modified, and the best perioperative strategy carefully tailored. These data should thus be used as reference points not only in preoperative assessment but also in planning the perioperative course, from pre-habilitation to adequate intraoperative management to complications prevention and care continuity after discharge. It is from such a far-seeing approach that issues emerged from preoperative evaluation can really contribute to decision-making about surgery in the elderly. PMID- 29446037 TI - Developing Healthy Food Preferences in Preschool Children Through Taste Exposure, Sensory Learning, and Nutrition Education. AB - PURPOSE OF REVIEW: The present review was undertaken in order to summarize and evaluate recent research investigating taste exposure, sensory learning, and nutrition education interventions for promoting vegetable intake in preschool children. RECENT FINDINGS: Overall, taste exposure interventions yielded the best outcomes for increasing vegetable intake in early childhood. Evidence from sensory learning strategies such as visual exposure and experiential learning also show some success. While nutrition education remains the most common approach used in preschool settings, additional elements are needed to strengthen the educational program for increasing vegetable intake. There is a substantial gap in the evidence base to promote vegetable intake in food fussy children. The present review reveals the relative importance of different intervention strategies for promoting vegetable intake. To strengthen intervention effects for improving vegetable intake in preschool children, future research could consider integrating taste exposure and sensory learning strategies with nutrition education within the preschool curriculum.

AB - BACKGROUND: Diarrhea significantly contributes to the global burden of diseases, particularly in developing countries. Rotavirus and norovirus are the most dominant viral agents responsible for diarrheal disease globally. The aim of this review was to conduct a comprehensive assessment of rotavirus and norovirus study in Indonesia. DATA SOURCES: Articles about rotavirus and norovirus surveillance in Indonesia were collected from databases, including PubMed and Google Scholar. Manual searching was performed to identify additional studies. Furthermore, relevant articles about norovirus diseases were included. RESULTS: A national surveillance of rotavirus-associated gastroenteritis has been conducted for years, resulting in substantial evidence about the high burden of the diseases in Indonesia. In contrast, norovirus infection received relatively lower attention and very limited data are available about the incidence and circulating genotypes. Norovirus causes sporadic and epidemic gastroenteritis globally. It is also emerging as a health problem in immunocompromised individuals. During post rotavirus vaccination era, norovirus potentially emerges as the most frequent cause of diarrheal diseases. CONCLUSIONS: Our review identifies knowledge gaps in Indonesia about the burden of norovirus diseases and the circulating genotypes. Therefore, there is a pressing need to conduct national surveillance to raise awareness of the community and national health authority about the actual burden of norovirus disease in Indonesia. Continuing rotavirus surveillance is also important to assess vaccine effectiveness and to continue tracking any substantial changes of circulating rotavirus genotypes. PMID- 29446041 TI - Characteristic findings of high-grade cervical intraepithelial neoplasia or more on magnifying endoscopy with narrow band imaging. AB - BACKGROUND: Colposcopy, which is a standard modality for diagnosing cervical intraepithelial neoplasia (CIN), can have limited accuracy owing to poor visibility. Flexible magnifying endoscopy with narrow band imaging (ME-NBI) has excellent diagnostic accuracy for early gastrointestinal neoplasms and is expected to be highly useful for CIN diagnosis. This study aimed to determine the characteristic findings and evaluate the diagnostic ability of ME-NBI for lesions >= CIN 3. METHODS: A well-designed prospective diagnostic case series conducted at multiple tertiary-care centers. A total of 24 patients who underwent cervical conization with a preoperative diagnosis of high-grade squamous cell intraepithelial lesions (HSILs) or lesions >= CIN 3 were enrolled. Prior to conization, still images and video of ME-NBI were captured to investigate the cervical lesions. The images were reviewed based on histological examination of the resected specimens. RESULTS: The NBI-ME images revealed the following abnormal findings: (1) light white epithelium (l-WE), (2) heavy white epithelium (h-WE), and (3) atypical intra-epithelial papillary capillary loop (IPCL). Pathological examination of the resected specimens confirmed cervical lesions >= CIN 3 in 21 patients. The ME-NBI findings were classified into four groups: l-WE, l-WE with atypical IPCL, h-WE, and h-WE with atypical IPCL, at rates of 0, 23.8, 9.5, and 66.7%, respectively. Additionally, all 3 patients with micro-invasive carcinoma showed a strong irregularity of IPCLs. CONCLUSION: The lesions >= CIN 3 demonstrated characteristic ME-NBI findings of h-WE alone, or l-/h-WE with atypical micro-vessels. This study indicates that ME-NBI may have novel value for CIN diagnosis. PMID- 29446042 TI - The clinical features of squamous cell lung carcinoma with sensitive EGFR mutations. AB - BACKGROUND: The process of selecting patients on the basis of epidermal growth factor receptor (EGFR) mutations would likely result in a patient population with greater sensitivity to EGFR tyrosine kinase inhibitors (EGFR-TKIs). However, EGFR mutation status is not routinely examined in patients with squamous cell lung cancer (Sq) because of the low incidence of EGFR mutations and the poor clinical response to EGFR-TKIs. METHODS: We retrospectively reviewed the clinical features of patients at our hospital with Sq who carried EGFR-TKI-sensitive EGFR mutations and assessed their responses to EGFR-TKIs. RESULTS: EGFR mutation status was tested in 23 of 441 patients with Sq (5.2%) admitted to our hospital during the study period. An EGFR mutation (exon 19 deletion 3, L858R 2) was identified in five of the 23 patients (21.7%), all of whom were female never-smokers. Of these five patients, four (4/9; 44.4%) were in the normal lung group, one (1/12; 8.3%) was in the emphysematous lung group, and none (0/2; 0%) in the fibrotic lung group. Two of these five patients with the EGFR mutation received gefitinib and two received afatinib. Although the two patients who were treated with gefitinib did not respond well to treatment (stable disease, 1 patient; progressive disease, 1 patient), the two patients who were treated with afatinib showed a good response (partial response, 2 patients). CONCLUSION: The administration of afatinib to Sq patients after selecting patients using the EGFR mutation test based on their underlying pulmonary disease and smoking status would likely result in a population with a greater sensitivity to afatinib. PMID- 29446043 TI - Long-term outcomes of postoperative taxane/platinum chemotherapy for early stage cervical cancer: a retrospective study. AB - BACKGROUND: Taxane/platinum (TP)-based combination chemotherapy is standard for the treatment of metastatic or recurrent cervical cancer. The aim of this study was to investigate the efficacy of postoperative TP therapy in early stage cervical cancer. METHODS: A retrospective review of patients with FIGO IB-IIB stage cervical cancer who were treated with radical hysterectomy and displayed surgical-pathological risk factors was performed. 122 patients were identified between 2003 and 2012. Survival was analyzed by Kaplan-Meier method and compared by the log-rank test. The Cox proportional hazards model was used to investigate predictors of survival. RESULTS: The median follow-up period was 82.4 months. The postoperative adjuvant therapy was TP in 82 (67.2%) patients, other chemotherapies in 10 (8.2%), radiotherapy (RT) in 25 (20.5%), and no further therapy (NFT) in 5 (4.1%). Survival was analyzed using 4 subgroups according to the postoperative adjuvant therapy. The estimated 5-year overall survival was 95.1% in the TP group, 90.0% in the other chemotherapy group, 78.9% in the RT group, and 100% in the NFT group. No significant difference of survival was observed in the subgroups. However, when analyzing only patients who displayed high-risk factors, non-TP adjuvant therapy (including RT and other chemotherapies) was independently associated with shorter survival on multivariate analysis. In the TP group, multivariate analysis revealed that a positive surgical margin was a significant predictor of shorter survival. CONCLUSIONS: Postoperative TP is effective in patients with surgically treated early stage cervical cancer. In these populations, a positive surgical margin could be associated with poor prognosis. PMID- 29446044 TI - Electrophysiological correlates of encoding processes in a full-report visual working memory paradigm. AB - Why are some visual stimuli remembered, whereas others are forgotten? A limitation of recognition paradigms is that they measure aggregate behavioral performance and/or neural responses to all stimuli presented in a visual working memory (VWM) array. To address this limitation, we paired an electroencephalography (EEG) frequency-tagging technique with two full-report VWM paradigms. This permitted the tracking of individual stimuli as well as the aggregate response. We recorded high-density EEG (256 channel) while participants viewed four shape stimuli, each flickering at a different frequency. At retrieval, participants either recalled the location of all stimuli in any order (simultaneous full report) or were cued to report the item in a particular location over multiple screen displays (sequential full report). The individual frequency tag amplitudes evoked for correctly recalled items were significantly larger than the amplitudes of subsequently forgotten stimuli, regardless of retrieval task. An induced-power analysis examined the aggregate neural correlates of VWM encoding as a function of items correctly recalled. We found increased induced power across a large number of electrodes in the theta, alpha, and beta frequency bands when more items were successfully recalled. This effect was more robust for sequential full report, suggesting that retrieval demands can influence encoding processes. These data are consistent with a model in which encoding-related resources are directed to a subset of items, rather than a model in which resources are allocated evenly across the array. These data extend previous work using recognition paradigms and stress the importance of encoding in determining later VWM retrieval success. PMID- 29446045 TI - Effects of extracellular orotic acid on acute contraction-induced adaptation patterns in C2C12 cells. AB - Dietary administration of orotic acid (OA), an intermediate in the pyrimidine biosynthetic pathway, is considered to provide a wide range of beneficial effects, including cardioprotection and exercise adaptation. Its mechanisms of action, when applied extracellularly, however, are barely understood. In this study, we evaluated potential effects of OA on skeletal muscle using an in vitro contraction model of electrically pulse-stimulated (EPS) C2C12 myotubes. By analyzing a subset of genes representing inflammatory, metabolic, and structural adaptation pathways, we could show that OA supplementation diminishes the EPS provoked expression of inflammatory transcripts (interleukin 6, Il6; chemokine (C X-C Motif) ligand 5, Cxcl5), and attenuated transcript levels of nuclear receptor subfamily 4 group A member 3 (Nr4A3), early growth response 1 (Egr1), activating transcription factor 3 (Atf3), and fast-oxidative MyHC-IIA isoform (Myh2). By contrast, OA had no suppressive effect on the pathogen-provoked inflammatory gene response in skeletal muscle cells, as demonstrated by stimulation of C2C12 myotubes with bacterial LPS. In addition, we observed a suppressive effect of OA on EPS-induced phosphorylation of AMP-activated protein kinase (AMPK), whereas EPS-triggered phosphorylation/activation of the mammalian target of rapamycin (mTOR) was not affected. Finally, we demonstrate that OA positively influences glycogen levels in EP-stimulated myotubes. Taken together, our results suggest that in skeletal muscle cells, OA modulates both the inflammatory and the metabolic reaction provoked by acute contraction. These results might have important clinical implications, specifically in cardiovascular and exercise medicine. PMID- 29446046 TI - Anti-neovascularization effects of DMBT in age-related macular degeneration by inhibition of VEGF secretion through ROS-dependent signaling pathway. AB - Choroidal neovascularization (CNV) is the hallmark of late-staged wet age-related macular degeneration (AMD). Vascular endothelial growth factor (VEGF) is a key component in the development and progression of wet AMD. DMBT, 6,6'-bis(2,3 dimethoxybenzoyl)-alpha,alpha-D-trehalose, had been proved that it could suppress tumor angiogenesis and metastasis by inhibiting production of VEGF. But the effects of DMBT on CNV were not known. This study was to investigate effects and mechanisms of DMBT on CNV in vitro and in vivo. Results showed that DMBT could inhibit migration and tube formation of RF/6A cells under ARPE-19 hypoxia conditioned medium. DMBT could reduce lesion area in laser-induced CNV model mice. ELISA and Western blotting assay showed that DMBT markedly inhibited secretion of VEGF in vitro and in vivo. Furthermore, DMBT restrained ROS level under hypoxia via suppressing Nrf2/HO-1 pathway. DMBT effectively suppressed hypoxia-induced the up-regulation of p-Akt, p-NF-kappaB, and HIF-1alpha. These results suggest that DMBT can inhibit CNV by down-regulation of VEGF in retina through Akt/NF-kappaB/HIF-1alpha and ERK/Nrf2/HO-1/HIF-1alpha pathway. DMBT might be a promising lead molecule for anti-CNV and serve as a therapeutic agent to inhibit CNV. PMID- 29446047 TI - Epigallocatechin gallate suppresses hepatic cholesterol synthesis by targeting SREBP-2 through SIRT1/FOXO1 signaling pathway. AB - This study aims to explore the effect of epigallocatechin gallate (EGCG) on blood lipids, liver lipids, and cholesterol synthesis in hyperlipidemic rats. SREBP-2 transgenic rats were used to investigate the transcriptional level of SREBP-2 regulated by SIRT-1/FOXO1 and the molecular mechanism of rate-limiting enzyme HMGCR that affects cholesterol synthesis. Rat models of hyperlipidemia were established and administered EGCG. Cholesterol synthesis was observed. Enzyme linked immunosorbent assay was used to determine serum triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), free fatty acid (FFA), superoxide dismutase (SOD), malondialdehyde (MDA), and T-AOC contents. Hematoxylin-eosin staining and oil red O staining were utilized to observe the histological changes in the liver. Biochemical method was applied to measure serum ALT and AST changes. Western blot assay and qRT-PCR were employed to detect the changes in SIRT1/FOXO1 pathway-related proteins, cholesterol synthesis-related genes, and SREBP-2. EGCG 50 mg/kg could obviously decrease the liver weight and liver coefficient, reduce serum TG, TC, LDL-C, and FFA levels (P < 0.05), and increase serum HDL-C levels in hyperlipidemic rats. EGCG could diminish hyperlipidemia-induced liver injury and reduce serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels. Oil red O staining results demonstrated that the number of red lipid droplets in hepatocytes reduced to varying degrees, especially high-dose EGCG. EGCG remarkably diminished MDA content in the liver with hypercholesterolemia and increased T-AOC and SOD activity. In the model group, SIRT1 expression increased, and FOXO1 expression decreased. EGCG activated SIRT1 and increased FOXO1 expression, whose expression trend was consistent with the fenofibrate group. HMGCR, FDPS, SS, and ABCA1 expression increased, and ACAT2 expression noticeably reduced in SREBP-2+/+ transgenic rats. EGCG could reverse the expression trend of each gene. Simultaneously, EGCG increased FOXO1 expression, and decrease SREBP-2 expression; however, no significant changes in these expression were found in SREBP-2-/- rats. EGCG can alleviate liver injury and oxidative stress in hyperlipidemic rats. EGCG can activate SIRT1, activate FOXO1 protein, regulate SREBP-2 protein, and inhibit hepatic cholesterol synthesis. PMID- 29446049 TI - ? PMID- 29446048 TI - Adiponectin and colon cancer: evidence for inhibitory effects on viability and migration of human colorectal cell lines. AB - Adiponectin (Acrp30) is an adipokine widely studied for its beneficial metabolic and anti-inflammatory properties. Colorectal cancer is among the most common cancers worldwide. The aim of present study was to explore the effects of Acrp30 on both CaCo-2 and HCT116 colorectal cancer cells in terms of viability, oxidative stress, and apoptosis. In addition, since colorectal cancer represents a typical inflammation-related cancer, we investigated whether Acrp30 treatment modifies the migration and the expression of crucial proteins in the EMT transition. Finally, we analyzed the expression of cytokines in CaCo-2 cells. We found that Acrp30 reduces the survival rate of both CaCo-2 and HCT116 cells through induction of apoptosis and oxidative stress already after 24 h of treatment. In addition, wound-healing assay indicated that Acrp30 exposure statistically inhibits CaCo-2 and HCT116 cell migration. Western blot analysis performed on E-cadherin and vimentin, two EMT crucial markers in carcinogenesis, indicated that Acrp30 does not influence EMT transition. Finally, we found a reduction of mRNA levels corresponding to the anti-inflammatory IL-10 cytokine together with an increase of the pro-inflammatory IL-6 and IL-8 cytokines. This study provides new insight into Acrp30 molecular effects on colorectal cancer cells. Indeed, even if further studies are necessary to clarify the precise role of Acrp30 in colorectal cancer, our data strongly suggest that Acrp30 negatively regulates cell survival and migration in association with induction of oxidative stress and regulation of cytokines expression in both CaCo-2 and HCT116 colorectal cells. PMID- 29446050 TI - Coping Mechanisms for Psychosomatic Symptoms among Aging Roman Catholic German priests. AB - To identify and investigate coping mechanisms and other factors which may impact upon the psychosomatic symptoms of aging German Roman Catholic priests. A cross sectional study was conducted among 499 aging German Roman Catholic priests with standardized questionnaires: Brief Symptom Inventory, Coping Inventory Stressful Situations, and Religious Coping Scale. Task-Oriented Coping exhibited a significant difference between the two groups. Multiple regression analyses indicated that psychosomatic symptoms could be best predicted by means of Task Oriented Coping mechanisms, identification with priesthood, and by a low Negative Religious Coping. The success of adaptive coping processes for older clergy may depend on how they employ strategies, strengthen their spiritual dimensions, and manage important psychosocial aspects of aging. In our sample, Depression and Somatization are explained best by Emotion-Oriented Coping. It is desirable for aging priests to be aware of protective factors like Role Identification, Task Oriented Coping, and low Negative Religious Coping, which may be helpful in improving their psychological well-being.

PMID- 29446054 TI - Upregulation of Pro-inflammatory Cytokine Expression Following Chronic Paracetamol Treatment in Astrocyte. AB - The present study aimed to investigate the effect of APAP treatment on the expression of pro-inflammatory cytokines in the astrocytes. The mouse astrocyte cells (C8-D1A) were treated with APAP at the concentration of 100 MUM for 24 h, 16 and 28 days. The expressions of pro-inflammatory cytokines and NF-kB were determined using western blot analysis. Furthermore, the expression and localization of phosphorylation of NF-kB were detected by immunohistochemical and immunofluorescent analysis. The ultrastructure of C8-D1A cells was as well monitored. The results revealed that acute APAP treatment (24 h) had no effect on the expression of pro-inflammatory cytokines and pNF-kB. This treatment did not alter the ultrastructure of C8-D1A cells when compared with those in the control cells. However, the results obtained from the study on chronic APAP-treated cells (16 and 28 days) showed the different effect of APAP treatment. The results obtained from western blot analysis showed the increment of pro-inflammatory cytokine (IL-1beta and TNF-alpha) expressions and the activation of NF-kB signaling pathway. Nuclear translocation of pNF-kB and alteration of several cell structures were well observed in the C8-D1A cells with chronic APAP treatment. The results obtained from this study suggest that chronic APAP treatment can induce an upregulation of pro-inflammatory cytokines (IL-1beta and TNFalpha) in astrocytes. This alteration implies the involvement of the activation of NF-kB signaling pathway. PMID- 29446053 TI - Systems pharmacological analysis of mitochondrial cardiotoxicity induced by selected tyrosine kinase inhibitors. AB - Tyrosine kinase inhibitors (TKIs) are targeted therapies rapidly becoming favored over conventional cytotoxic chemotherapeutics. Our study investigates two FDA approved TKIs, DASATINIB; indicated for IMATINIB-refractory chronic myeloid leukemia, and SORAFENIB; indicated for hepatocellular carcinoma and advanced renal cell carcinoma. Limited but crucial evidence suggests that these agents can have cardiotoxic side effects ranging from hypertension to heart failure. A greater understanding of the underlying mechanisms of this cardiotoxicity are needed as concerns grow and the capacity to anticipate them is lacking. The objective of this study was to explore the mitochondrial-mediated cardiotoxic mechanisms of the two selected TKIs. This was achieved experimentally using immortalized human cardiomyocytes, AC16 cells, to investigate dose- and time dependent cell killing, along with measurements of temporal changes in key signaling proteins involved in the intrinsic apoptotic and autophagy pathways upon exposure to these agents. Quantitative systems pharmacology (QSP) models were developed to capture the toxicological response in AC16 cells using protein dynamic data. The developed QSP models captured well all the various trends in protein signaling and cellular responses with good precision on the parameter estimates, and were successfully qualified using external data sets. An interplay between the apoptotic and autophagic pathways was identified to play a major role in determining toxicity associated with the investigated TKIs. The established modeling platform showed utility in elucidating the mechanisms of cardiotoxicity of SORAFENIB and DASATINIB. It may be useful for other small molecule targeted therapies demonstrating cardiac toxicities, and may aid in informing alternate dosing strategies to alleviate cardiotoxicity associated with these therapies. PMID- 29446055 TI - Which Costs Matter? Costs Included in Economic Evaluation and their Impact on Decision Uncertainty for Stable Coronary Artery Disease. AB - BACKGROUND: Variation exists in the resource categories included in economic evaluations, and National Institute for Health and Care Excellence (NICE) guidance suggests the inclusion only of costs related to the index condition or intervention. However, there is a growing consensus that all healthcare costs should be included in economic evaluations for Health Technology Assessments (HTAs), particularly those related to extended years of life. OBJECTIVE AND METHODS: We aimed to quantify the impact of a range of cost categories on the adoption decision about a hypothetical intervention, and uncertainty around that decision, for stable coronary artery disease (SCAD) based on a dataset comprising 94,966 patients. Three costing scenarios were considered: coronary heart disease (CHD) costs only, cardiovascular disease (CVD) costs and all costs. The first two illustrate different interpretations of what might be regarded as related costs. RESULTS: Employing a 20-year time horizon, the highest mean expected incremental cost was when all costs were included (L2468) and the lowest when CVD costs only were included (L2377). The probability of the treatment being cost effective, estimating health opportunity costs using a ratio of L30,000 per quality-adjusted life-year (QALY), was different for each of the CHD (70%) costs, CVD costs (73%) and all costs (56%) scenarios. The results concern a hypothetical intervention and are illustrative only, as such they cannot necessarily be generalised to all interventions and diseases. CONCLUSIONS: Cost categories included in an economic evaluation of SCAD impact on estimates of both cost effectiveness and decision uncertainty. With an aging and co-morbid population, the inclusion of all healthcare costs may have important ramifications for the selection of healthcare provision on economic grounds. PMID- 29446057 TI - In Vitro Evaluation of Probiotic Potential of Lactic Acid Bacteria Isolated from Yunnan De'ang Pickled Tea. AB - This study aimed to investigate the probiotic potential of lactic acid bacteria (LAB) strains isolated from De'ang pickled tea, a traditional food consumed by the De'ang nationality of Yunnan, China. Twenty-six LAB strains isolated from De'ang pickled tea were subjected to identification based on 16S rRNA gene sequence analysis. Twenty-four belonged to Lactobacillus plantarum, one belonged to Enterococcus casseliflavus, and one belonged to Lactobacillus acidophilus. Eighteen out of 26 LAB strains which showed a higher capability to tolerate simulated gastrointestinal juices were chosen to further evaluate their probiotic properties. Varied adhesive abilities and auto-aggregative capacities of selected LAB strains were dependent on species and even strains. All tested LAB strains were resistant to kanamycin, streptomycin, gentamycin, and vancomycin and sensitive to tetracycline and chloramphenicol. Ten out of the 18 strains are resistant to ampicillin, and the remaining strains are sensitive to ampicillin; 4 out of the 18 strains showed resistance to erythromycin. Compared to reference strain Lactobacillus rhamnosus strain GG, these LAB strains had a greater or comparative antimicrobial activity against Salmonella typhimurium or Escherichia coli. In contrast, eight out of the 18 strains suppressed growth of Shigella flexneri. Two L. plantarum strains, ST and STDA10, not only exhibited good probiotic properties but also showed a good ability of scavenging DPPH and ABTS+. This study suggests that L. plantarum ST and STDA10 could be used as potential probiotics applied in functional foods. PMID- 29446056 TI - Hypothesis: structural heterogeneity of the unfolded proteins originating from the coupling of the local clusters and the long-range distance distribution. AB - We propose a hypothesis that explains two apparently contradicting observations for the heterogeneity of the unfolded proteins. First, the line confocal method of the single-molecule Forster resonance energy transfer (sm-FRET) spectroscopy revealed that the unfolded proteins possess broad peaks in the FRET efficiency plot, implying the significant heterogeneity that lasts longer than milliseconds. Second, the fluorescence correlation method demonstrated that the unfolded proteins fluctuate in the time scale shorter than 100 ns. To formulate the hypothesis, we first summarize the recent consensus for the structure and dynamics of the unfolded proteins. We next discuss the conventional method of the sm-FRET spectroscopy and its limitations for the analysis of the unfolded proteins, followed by the advantages of the line confocal method that revealed the heterogeneity. Finally, we propose that the structural heterogeneity formed by the local clustering of hydrophobic residues modulates the distribution of the long-range distance between the labeled chromophores, resulting in the broadening of the peak in the FRET efficiency plot. A clustering of hydrophobic residues around the chromophore might further contribute to the broadening. The proposed clusters are important for the understanding of protein folding mechanism.

AB - BACKGROUND: Lupus nephritis (LN) is one of the most common and severe complications in Systemic lupus erythematosus patients, and the mechanism underlining the pathogenesis of LN is still unknown. Autophagy plays vital roles in maintaining cell homeostasis and is involved in the pathogenesis of many diseases. In this study, we investigated the role of autophagy in the progression of LN. METHODS: Autophagic activities in podocytes of both LN patients (Class IV and V) and mice were evaluated. Podocytes were observed by electron microscopy, and autophagic activity was evaluated by immunofluorescence staining and western blot analysis. Apoptotic activity was evaluated by immunohistochemistry, TUNEL assays and flow cytometric analysis. RESULTS: Significantly greater podocyte injury and discrepant autophagic levels were observed in LN patients. Differentiated mouse podocytes in the LN group showed reduced nephrin expression and increased apoptosis, as well as significantly higher levels of apoptosis related proteins (cleaved caspase-3 and Bax). In the mice LN group, the increased number of autophagosomes was accompanied by increased LC3-II/LC3-I ratios and decreased p62, suggesting increased autophagic and apoptotic activity in podocytes. Blockade of autophagic activity by 3-MA or siRNA-mediated silencing of Atg5 resulted in decreases in LC3-II/LC3-I ratios, podocyte apoptosis and damage in the mice LN group. Futhermore, Rapamycin treatment increased LC3-II/LC3-I ratios, and enhanced LN-induced apoptosis in podocyte from modal animal. CONCLUSIONS: This study demonstrates that autophagic activity of podocytes is a crucial factor in renal injury by directly affecting the function of podocyte; thus, inhibiting this activity during the early stages of LN is implicated as a potential therapeutic strategy for delaying the progression of LN. Also, clinical application in LN needs to consider patients' pathological type and drugs' comprehensive effectiveness. PMID- 29446060 TI - Effect of adding midazolam to bupivacaine during rectus sheath block: a randomised controlled trial. AB - BACKGROUND: Various adjuvants have been tried to improve quality and increase duration of local anaesthetics during various nerve blocks. We aimed to evaluate the effect of adding midazolam to bupivacaine on rectus sheath (RS) block in patients undergoing umbilical or epigastric hernia repair. METHODS: In all, 60 adult patients were divided into two equal groups, each group included 30 patients. Group I received 20 ml of bupivacaine hydrochloride 0.25% + midazolam 50 MUg/kg in 2 ml saline 0.9% (Midazolam group, n = 30), whereas Group II received 20 ml of bupivacaine hydrochloride 0.25% + 2 ml saline (Control group, n = 30) for RS block on each side. The primary outcome was post-operative 48 h morphine consumption, whereas secondary outcomes included analgesia duration, post-operative pain, as evaluated by visual analogue scale (VAS) for pain scoring at 1, 2, 6, 12, 24 and 48 h post-operatively, reported post-operative nausea and or vomiting (PONV), somnolence or any adverse drug reactions. RESULTS: The current study showed that addition of midazolam to bupivacaine for RS blockade provided good analgesia as evidenced by a statistically significant less morphine consumption in the post-operative 48 h [11.2 (5.3-18.3) vs. 25.9 (15.2-31.0) mg, P = 0.002], longer duration of analgesia, lower VAS during post-operative 48 h, lower incidence of PONV, somnolence and pruritus. CONCLUSION: Midazolam addition to bupivacaine for RS blockade provided adjuvant analgesia as supported by less morphine consumption, longer duration of analgesia, and lower VAS score. PMID- 29446061 TI - Viewpoints of dentists on the use of bisphosphonates in rheumatology patients. AB - OBJECTIVES: Alhough typically prescribed in oncology, bisphosphonates (BPs) are also employed in rheumatology, particularly for the treatment of osteoporosis, sometimes resulting in complications, such as osteonecrosis of the jaw. Because of different opinions between rheumatologists and dentists on BP use, this study aimed to assess the views of dentists regarding administration of BPs in rheumatology. METHODS: A questionnaire was sent to 880 dentists from the Auvergne region of France to determine their views on BP treatment. RESULTS: We obtained 382 (43.4%) responses and analysed 376 (58.7% men). In total, 156 (41.5%) of the responders analysed had attended an in-service training course (ISTC) on the topic. A total of 237 (63.0%) systematically inquired as to whether their patients were undergoing BP treatment; this proportion was higher among those who had been practicing for fewer than 10 years (P < 0.004). For patients receiving BPs, 84.5% of practitioners felt ill at ease about performing dental surgery (n = 318) and 11% felt ill at ease about performing nonsurgical dental care (n = 41); 67% stated that their practice differed depending on the method of BP administration (per os or intravenously). Overall, 53.7% of practitioners felt uncomfortable when asked by a rheumatologist whether a given patient's dental status permitted prescription of BP (n = 202). This proportion was higher among those who had never attended an ISTC (62.6% vs. 50.7%; P < 0.03). CONCLUSIONS: Dentists feel ill at ease providing dental surgery to patients receiving BPs. Closer collaboration and better information-sharing between rheumatologists and dentists is necessary to facilitate the administration of BPs in rheumatology. PMID- 29446062 TI - Predicted MHC peptide binding promiscuity explains MHC class I 'hotspots' of antigen presentation defined by mass spectrometry eluted ligand data. AB - Peptides that bind to and are presented by MHC class I and class II molecules collectively make up the immunopeptidome. In the context of vaccine development, an understanding of the immunopeptidome is essential, and much effort has been dedicated to its accurate and cost-effective identification. Current state-of-the art methods mainly comprise in silico tools for predicting MHC binding, which is strongly correlated with peptide immunogenicity. However, only a small proportion of the peptides that bind to MHC molecules are, in fact, immunogenic, and substantial work has been dedicated to uncovering additional determinants of peptide immunogenicity. In this context, and in light of recent advancements in mass spectrometry (MS), the existence of immunological hotspots has been given new life, inciting the hypothesis that hotspots are associated with MHC class I peptide immunogenicity. We here introduce a precise terminology for defining these hotspots and carry out a systematic analysis of MS and in silico predicted hotspots. We find that hotspots defined from MS data are largely captured by peptide binding predictions, enabling their replication in silico. This leads us to conclude that hotspots, to a great degree, are simply a result of promiscuous HLA binding, which disproves the hypothesis that the identification of hotspots provides novel information in the context of immunogenic peptide prediction. Furthermore, our analyses demonstrate that the signal of ligand processing, although present in the MS data, has very low predictive power to discriminate between MS and in silico defined hotspots. PMID- 29446063 TI - Direct and Indirect Healthcare Resource Utilization and Costs Among Migraine Patients in the United States. AB - OBJECTIVE: The goal of this analysis was to provide a contemporary estimate of the burden of migraine, incorporating both direct and indirect costs, by comparing the costs of migraine patients to a matched group of patients without migraine in a large, nationally representative sample of commercially insured patients in the United States. BACKGROUND: Previous studies have shown that the economic burden of migraine in the United States is substantial for payers, patients, and employers. Despite the availability of multiple acute and preventive pharmacological treatment options and a relatively stable migraine prevalence in the United States, there has been a documented increase in migraine related healthcare resource and pharmacy use. Given the frequently disabling nature of migraine and its high prevalence, especially during peak productive years, and the lack of recent estimates of the burden of migraine, there is a need to update the existing literature with more current data. METHODS: This retrospective, observational cohort study identified migraine patients in the Truven Health Market Scan Research Databases between January 2008 and June 2013. Adult patients had 12 months of continuous enrollment before (baseline period) and after (follow-up period) the day they received migraine diagnoses and/or medications (index) and no diagnosis of HIV or malignancy during the study period. The patients with migraine were matched 1:1 to a group of patients without migraine on demographic variables and index date. Direct healthcare utilization and costs and indirect (absenteeism, short-term disability, and long term disability) costs were assessed during the 12-month follow-up period and differences between patients with vs without migraine were assessed. Two additional multivariable logistic regression analyses were conducted. First, an analysis was conducted comparing the odds of having a short-term disability claim between patients with and without migraine after controlling for patient demographic and clinical characteristics. A second analysis, conducted among the migraine patients only, compared the odds of having a short-term disability claim between (1) patients treated with acute or preventive migraine medications only during the baseline period and patients with no migraine treatment during baseline and (2) patients treated with both acute and preventive migraine medications during the baseline period and patients with no migraine treatment during baseline, after controlling for patient demographic and clinical characteristics. RESULTS: Migraine patients had total annual direct plus indirect costs that were $8924 (in 2014 United States dollars) higher than those of demographically similar individuals without evidence of migraine. Migraine patients' mean annual direct all-cause healthcare costs were $6575 higher than those of matched patients without migraine ($11,010 [standard deviation = $19,663] vs $4436 [standard deviation=$13,081]; P < .01). Total mean annual indirect costs were $2350 higher in the migraine cohort than in the matched no migraine patients ($11,294 vs $8945. Migraine patients were 2.0 times more likely as their nonmigraine counterparts to use opioids (45.5% vs 21.9%; P < .01) and among patients with opioid prescriptions, migraine patients had 1.8 times the number of opioid prescriptions per patient than did those without migraine (4.9 [standard deviation = 6.9] vs 2.7 [standard deviation = 4.0]; P < .01). After adjusting for baseline demographic and clinical characteristics, migraine patients treated with either acute or preventive migraine medications (odds ratio = 0.81 [95% confidence interval = 0.72-0.91]; P < .01) or both acute and preventive migraine medications during the baseline period (odds ratio = 0.93 [95% confidence interval = 0.89-0.98]; P < .01) were significantly less likely to have short-term disability claims than untreated patients during the follow-up period (Migraine patients with either acute or preventive medications only: 7290/45,632 [16.0%]; with both acute and preventive medications: 3085/14,941 [20.6%]; untreated patients: 1604/11,169 [14.4%] had a short-term disability claim.) However, overall, migraine patients had 1.94 times the odds of having a short-term disability claim than their matched counterparts (95% confidence interval = 1.83-2.05; P < .01; migraine patients: 11,979/71,742 [16.7%]; nonmigraine patients: 4801/71,742 [6.7%] had a short-term disability claim). CONCLUSIONS: Results from this real-world assessment of the economic burden of migraine suggest that migraine imposes a substantial direct and indirect cost burden in the United States. Compared to matched nonmigraine patients, migraine patients were more likely to have work loss and longer periods of work loss, leading to significantly higher indirect costs. Migraine patients also had higher levels of healthcare utilization, despite the relatively stable prevalence of migraine and the available acute and preventive treatment options for migraine management. PMID- 29446064 TI - Roles of community pharmacists in improving oral health awareness in Plateau State, Northern Nigeria. AB - INTRODUCTION: There is poor oral health awareness in Nigeria because of limited access to correct information on oral health as well as a lack of oral health care providers. The purpose of this study was to describe the roles of community pharmacists (CPs) in Plateau State, Northern Nigeria, as sources of oral health information in their communities. METHODS: A quantitative cross-sectional study on CPs spanning the entire State. Data collection was a survey method using a structured paper-based self-administered questionnaire. Analysis, which included t-tests and binary logistic regression, was carried out using SPSS ver. 23. RESULTS: A one-sample t-test to assess the attitudes of CPs on oral health showed that they had a very good disposition towards engaging in oral health services [advice, referrals, recommendations and basic treatment (e.g. of pain); mean = 4.54, standard deviation = 0.59, t(111) = 27.8, P < 0.001]. Although CPs presently provide some services to patients with oral health problems, 94.7% were willing to do more to advance the cause of oral health care. Training of CPs on oral health (32%), removal of restrictive policies in the health bill (1.8%) and sensitising the public (6.3%) were some suggestions on how to improve these services. CONCLUSION: The disposition of CPs towards improving oral health could serve as a platform to help propagate oral health care and awareness in their communities. Engaging the CPs might help to reduce oral health disparities by increasing oral health awareness and improving the quality of life via cost effective delivery of pharmacy-based oral health-care services. PMID- 29446065 TI - Simulating Variation in Families' Spending across Marketplace Plans. AB - OBJECTIVE: To examine variations in premium and cost-sharing across marketplace plans available to eligible families. DATA SOURCES: 2011-2012 Medical Expenditure Panel Survey (MEPS), 2014 health plan data from healthcare.gov, and the 2011 Medicare Part D public formulary file. STUDY DESIGN: We identified a nationally representative cohort of individuals in the MEPS who would have been eligible for marketplace coverage. For each family, we simulated the total out-of-pocket payment (premium plus cost-sharing) under each available plan in their county of residence, assuming their premarketplace use. DATA COLLECTION/EXTRACTION METHODS: Confidential state and county of residence identifiers were merged onto MEPS public use files and used to match MEPS families to the plans available in their county as reported in the publicly available data from healthcare.gov. PRINCIPAL FINDINGS: We found substantial variation in total family health care spending, especially premium component, across marketplace plans. This is true even within a plan tier of the same minimum actuarial value, and for families eligible for subsidies. Variation among families with income below 250 percent of the FPL is larger than variation among families with higher income. CONCLUSIONS: Our simulations show substantial variations in net premium and out-of-pocket payments across marketplace plans, even within a plan tier. PMID- 29446066 TI - Resource Use During the Last 6 Months of Life of Individuals Dying with and of Alzheimer's Disease. AB - OBJECTIVES: To compare resource use during the last 6 months of life of individuals diagnosed with Alzheimer's disease (AD) but for whom AD was not formally identified as the underlying cause of death (dying with AD) with that of those who had AD as underlying cause of death (dying of AD). DESIGN: Full population retrospective analysis. SETTING: Belgium. PARTICIPANTS: All Belgian decedents in 2012. MEASUREMENTS: We linked participants' healthcare, population, and death certificate data. Those who died of AD were selected based on underlying cause of death. Those who died with AD were selected using a validated algorithm. RESULTS: Individuals who died of AD had less hospital use than those who died with AD; were less often admitted to a palliative care unit but received palliative home care services slightly more often; and had use of physiotherapy, noninvasive ventilation, medical imaging, sedatives, oxygen, and opioids comparable with that of those who died with AD. CONCLUSION: During the last 6 months of life, individuals dying of AD used fewer intensive resources such as intensive care unit, cardiopulmonary resuscitation, and invasive ventilation than those dying with AD, which suggests the effect of recognition of an end-of-life phase. Overall, individuals with AD rarely used palliative care services, suggesting a need for more efforts to encourage use of palliative care in individuals with AD. PMID- 29446067 TI - Headache Linked to Intracranial Hypertension and Hypertrophic Pachymeningitis as the Initial and Dominant Presentation of Granulomatosis With Polyangiitis. Case Report and Review of the Recent Literature. AB - OBJECTIVE: The objective of this article is to report a rare case of headache as the initial symptom of granulomatosis with polyangiitis (GPA) and to review the recent literature. BACKGROUND: Granulomatosis with polyangiitis is a rare, systemic, autoimmune disease of unknown etiology. GPA has a wide spectrum of clinical symptomatology, including involvement of the nervous system, even as the initial manifestation. Symptoms of the peripheral nervous system used to dominate the clinical symptomatology. However, recent reports are focusing increasingly in granulomatous lesions of the central nervous system, and especially on the increased frequency of patients with hypertrophic pachymeningitis (HP). We report the case of a patient with headache linked to intracranial hypertension and hypertrophic pachymeningitis as the initial and dominant presentation of GPA and we review the recent literature. METHODS: A 54-year-old male, without any related medical history developed a severe headache. In the following 2 months, he gradually developed hoarseness and diplopia at the left and lower fields of vision. A brain MRI revealed wide-spread fattening and meningeal enhancement over the left hemisphere and the left cerebellar hemisphere. An endoscopy of the pharynx revealed the presence of a tumor-like mass in the left half of the nasopharynx. A biopsy showed inflammation with presence of polykaryocyte Langhans giant cells. The laboratory testing revealed important albuminuria and microhematuria, positive c-ANCA and negative p-ANCA. A diagnosis of GPA was established. RESULTS: A steroid treatment was administered initially, which improved the headache drastically, followed by the administration of a combination of cyclophosphamide and corticosteroid, which led to a gradual resolve of the remaining symptomatology. A follow-up brain MRI showed a decrease in meningeal enhancement, whereas a second one, 2 years later, was completely normal. CONCLUSIONS: HP was considered an extremely rare manifestation of GPA. However, recent studies are reporting an increased frequency of HP and are distinguishing a granulomatous and a vasculitic phenotype, with different localization and relapse rates, that may eventually constitute a different clinical spectrum of GPA. PMID- 29446068 TI - Model-Informed Drug Development for Ixazomib, an Oral Proteasome Inhibitor. AB - Model-informed drug development (MIDD) was central to the development of the oral proteasome inhibitor ixazomib, facilitating internal decisions (switch from body surface area (BSA)-based to fixed dosing, inclusive phase III trials, portfolio prioritization of ixazomib-based combinations, phase III dose for maintenance treatment), regulatory review (model-informed QT analysis, benefit-risk of 4 mg dose), and product labeling (absolute bioavailability and intrinsic/extrinsic factors). This review discusses the impact of MIDD in enabling patient-centric therapeutic optimization during the development of ixazomib. PMID- 29446069 TI - Accelerated Development of the Dual Orexin Receptor Antagonist ACT-541468: Integration of a Microtracer in a First-in-Human Study. AB - The orexin system regulates sleep and arousal and is targeted by ACT-541468, a new dual orexin receptor antagonist (DORA). Healthy male subjects received a single oral dose of 5-200 mg to assess safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), mass balance, metabolism, and absolute bioavailability utilizing a 14 C-labeled, orally and intravenously (i.v.) administered microtracer. The drug was safe and well tolerated; the PK profile was characterized by quick absorption and elimination, with median time to reach maximum concentration (tmax ) of 0.8-2.8 h and geometric mean terminal half-life (t1/2 ) of 5.9-8.8 h. Clear dose-related effects on the central nervous system were observed at >=25 mg, indicating a suitable PK-PD profile for a sleep promoting drug, allowing for rapid onset and duration of action limited to the intended use. This comprehensive first-in-human study created a wealth of data, while saving resources in drug development. PMID- 29446070 TI - A Hospital Based Retrospective Study of Acute Postpartum Headache. AB - OBJECTIVE: To describe acute headache diagnoses in women presenting emergently in the postpartum period and to determine which factors may be associated with secondary vs primary headache. BACKGROUND: Hormonal, vascular, and procedural factors elevate the risk for both secondary and primary headache disorders in the postpartum period. Differentiating between these can be a diagnostic challenge, particularly among the most severe patients referred for urgent neurological consultation. METHODS: A single-center retrospective study of consecutive postpartum women age >=18 years presenting with acute headache to a large urban tertiary-care hospital and receiving neurological consultation. RESULTS: Of 63 women who presented with acute postpartum headache, 17 (27.0%) were diagnosed with a primary headache disorder and 46 (73.0%) were diagnosed with a secondary headache disorder. Migraine comprised the majority of primary headache diagnoses (76.5%). Secondary headache most commonly featured postdural puncture headache (PDPH) (45.7%), postpartum preeclampsia (PEC) (26.1%), and a diverse group of cerebrovascular headache disorders (21.7%). Presentation within 24 hours and lack of side predominance helped to differentiate PDPH from migraine. However, abnormal diagnostic testing was more prevalent in the patients with headache secondary to cerebrovascular disorders/PEC. CONCLUSIONS: Nearly three-quarters of postpartum women who present with acute onset headache and receiving neurological consultation are found to have a secondary headache - with nearly half of the secondary headaches attributed to PEC or cerebrovascular headache disorders. The absence of a headache history and a clear PDPH description should prompt strong consideration for neuroimaging to rule out cerebrovascular etiologies of headache as well as close monitoring for signs and symptoms of preeclampsia in women presenting with acute severe postpartum headache. PMID- 29446071 TI - Indistinguishability tests in the actor-partner interdependence model. AB - When considering dyadic data, one of the questions is whether the roles of the two dyad members can be considered equal. This question may be answered empirically using indistinguishability tests in the actor-partner interdependence model. In this paper several issues related to such indistinguishability tests are discussed: the difference between maximum likelihood and restricted maximum likelihood based tests for equality in variance parameters; the choice between the structural equation modelling and multilevel modelling framework; and the use of sequential testing rather than one global test for a set of indistinguishability tests. Based on simulation studies, we provide guidelines for best practice. All different types of tests are illustrated with cross sectional and longitudinal data, and corroborated with corresponding R code. PMID- 29446072 TI - Sleep in a comparative context: Investigating how human sleep differs from sleep in other primates. AB - OBJECTIVES: Primates vary in their sleep durations and, remarkably, humans sleep the least per 24-hr period of the 30 primates that have been studied. Using phylogenetic methods that quantitatively situate human phenotypes within a broader primate comparative context, we investigated the evolution of human sleep architecture, focusing on: total sleep duration, rapid eye movement (REM) sleep duration, non-rapid eye movement (NREM) sleep duration, and proportion of sleep in REM. MATERIALS AND METHODS: We used two different Bayesian methods: phylogenetic prediction based on phylogenetic generalized least squares and a multistate Onrstein-Uhlenbeck (OU) evolutionary model of random drift and stabilizing selection. RESULTS: Phylogenetic prediction confirmed that humans sleep less than predicted for a primate of our body mass, predation risk, brain size, foraging needs, sexual selection, and diet. These analyses further revealed that humans pack an unexpectedly higher proportion of REM sleep within a shorter overall sleep duration, and do so by reducing NREM sleep (rather than increasing REM). The OU model generally confirmed these findings, with shifts along the human lineage inferred for TST, NREM, and proportion of REM, but not for REM. DISCUSSION: We propose that the risks and opportunity costs of sleep are responsible for shorter sleep durations in humans, with risks arising from terrestrial sleep involving threats from predators and conspecifics, and opportunity costs because time spent sleeping could be used for learning, creating material objects, and socializing. PMID- 29446073 TI - CCR2-dependent Gr1high monocytes promote kidney injury in shiga toxin-induced hemolytic uremic syndrome in mice. AB - The hemolytic uremic syndrome (HUS) is a life-threatening disease of the kidney that is induced by shiga toxin-producing E.coli. Major changes in the monocytic compartment and in CCR2-binding chemokines have been observed. However, the specific contribution of CCR2-dependent Gr1high monocytes is unknown. To investigate the impact of these monocytes during HUS, we injected a combination of LPS and shiga toxin into mice. We observed an impaired kidney function and elevated levels of the CCR2-binding chemokine CCL2 after shiga toxin/LPS- injection, thus suggesting Gr1high monocyte infiltration into the kidney. Indeed, the number of Gr1high monocytes was strongly increased one day after HUS induction. Moreover, these cells expressed high levels of CD11b suggesting activation after tissue entry. Non-invasive PET-MR imaging revealed kidney injury mainly in the kidney cortex and this damage coincided with the detection of Gr1high monocytes. Lack of Gr1high monocytes in Ccr2-deficient animals reduced neutrophil gelatinase-associated lipocalin and blood urea nitrogen levels. Moreover, the survival of Ccr2-deficient animals was significantly improved. Conclusively, this study demonstrates that CCR2-dependent Gr1high monocytes contribute to the kidney injury during HUS and targeting these cells is beneficial during this disease. PMID- 29446075 TI - Surface smoothing, decimation, and their effects on 3D biological specimens. AB - OBJECTIVE: Smoothing and decimation filters are commonly used to restore the realistic appearance of virtual biological specimens, but they can cause a loss of topological information of unknown extent. In this study, we analyzed the effect of smoothing and decimation on a 3D mesh to highlight the consequences of an inappropriate use of these filters. MATERIALS AND METHODS: Topological noise was simulated on four anatomical regions of the virtual reconstruction of an orangutan cranium. Sequential levels of smoothing and decimation were applied, and their effects were analyzed on the overall topology of the 3D mesh and on linear and volumetric measurements. RESULTS: Different smoothing algorithms affected mesh topology and measurements differently, although the influence on the latter was generally low. Decimation always produced detrimental effects on both topology and measurements. The application of smoothing and decimation, both separate and combined, is capable of recovering topological information. CONCLUSION: Based on the results, objective guidelines are provided to minimize information loss when using smoothing and decimation on 3D meshes. PMID- 29446076 TI - Topical application of glycyrrhetinic acid in the gingival sulcus inhibits attachment loss in lipopolysaccharide-induced experimental periodontitis in rats. AB - BACKGROUND AND OBJECTIVE: Attachment loss of the junctional epithelium and alveolar bone destruction are signs of periodontitis, which is mainly caused by an inflammatory response to dental plaque. Glycyrrhetinic acid (GA), a component of the licorice herb, has been shown to have important anti-inflammatory activities; however, there are no previous reports on the ability of its inhibitory effects to prevent periodontal diseases. Hence, in this study, using our experimental periodontitis model, we attempted to evaluate whether GA had an effect on the prevention of attachment loss and alveolar bone loss. MATERIAL AND METHODS: Rats were intraperitoneally immunized with Escherichia coli lipopolysaccharide (LPS). The LPS group (n = 5) received 3 topical applications of 50 MUg/MUL of LPS followed by one application of the vehicle (propylene glycol:ethyl alcohol:phosphate-buffered saline [PBS] = 8:1:1) into the gingival sulcus. This protocol was repeated twice per day for 10 days. The low (n = 5) and high (n = 5) groups received topical application of LPS and 0.03% or 0.3% GA, respectively. The control group received topical application of PBS and vehicle. The rats were killed on the 10th day. Attachment loss, alveolar bone level and inflammatory cell infiltration were investigated histometrically. The formation of immune complexes and infiltration of LPS were evaluated immunohistologically. RESULTS: Attachment loss, formation of immune complexes and infiltration of inflammatory cells were increased in the LPS group compared with the control group, and were completely inhibited in the low and high groups compared with the LPS group. The LPS group showed greater alveolar bone destruction compared with the control group and GA-treated groups. In addition, invasion of LPS was detected in the LPS group, was absent in the control group and was weaker in the GA-treated groups than in the LPS group. CONCLUSION: In the present study, we showed that GA inhibits periodontal destruction in the rat experimental periodontitis model. PMID- 29446074 TI - A Hitchhiker's guide to humanized mice: new pathways to studying viral infections. AB - Humanized mice are increasingly appreciated as an incredibly powerful platform for infectious disease research. The often very narrow species tropism of many viral infections, coupled with the sometimes misleading results from preclinical studies in animal models further emphasize the need for more predictive model systems based on human cells rather than surrogates. Humanized mice represent such a model and have been greatly enhanced with regards to their immune system reconstitution as well as immune functionality in the past years, resulting in their recommendation as a preclinical model by the US Food and Drug Administration. This review aims to give a detailed summary of the generation of human peripheral blood lymphocyte-, CD34+ haematopoietic stem cell- and bone marrow/liver/thymus-reconstituted mice and available improved models (e.g. myeloid- or T-cell-only mice, MISTRG, NSG-SGM3). Additionally, we summarize human tropic viral infections, for which humanized mice offer a novel approach for the study of disease pathogenesis as well as future perspectives for their use in biomedical, drug and vaccine research. PMID- 29446077 TI - Coffee drinking and colorectal cancer and its subsites: A pooled analysis of 8 cohort studies in Japan. AB - Coffee is a rich source of bioactive compounds that have potential anticarcinogenic effects. However, it remains unclear whether coffee drinking is associated with colorectal cancer. Also, despite different etiological factors involved in gut physiology, few studies have investigated this association by anatomical site of the lesion. To address these issues, this study examined the association between coffee drinking and colorectal cancer in a pooled analysis from 8 cohort studies conducted in Japan. Among 320,322 participants followed up for 4,503,274 person-years, 6,711 incident colorectal cancer cases were identified. Study-specific hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox proportional hazards models and then pooled using the random effects model. Coffee drinking was not materially associated with colorectal cancer risk in men or women (pooled HR 0.92, 95% CI 0.82-1.03 in men and pooled HR 0.90, 95% CI 0.76-1.07 in women). Analysis by subsite showed a lower risk of colon cancer among female drinkers of >=3 cups coffee/day (pooled HR 0.80, 95% CI 0.64-0.99). There was no such association in men. Coffee drinking was not associated with risk of rectal cancer in men or women. Results were virtually the same among never smokers except for an increased risk of rectal cancer associated with frequent coffee consumption. Coffee drinking may be associated with lower risk of colon cancer in Japanese women. PMID- 29446079 TI - Dietary intake of nutrients involved in one-carbon metabolism and risk of urothelial cell carcinoma: A prospective cohort study. AB - Nutrients involved in one-carbon metabolism may play a role in carcinogenesis through DNA replication, repair and methylation mechanisms. Most studies on urothelial cell carcinoma (UCC) have focused on folate. We sought to examine the association between B-group vitamins and methionine intake and UCC risk, overall and by subtype, and to test whether these associations are different for population subgroups whose nutritional status may be compromised. We followed participants in the Melbourne Collaborative Cohort Study (N = 41,513) for over 20 years and observed 500 UCC cases (89% originating in the bladder; superficial: 279, invasive: 221). Energy-adjusted dietary intakes of B vitamins (B1, B2, B3, B5, B6, B8, B9 and B12) and methionine were estimated from a 121-item food frequency questionnaire administered at baseline (1990-1994), using the residuals method. We used Cox regression models to compute hazard ratios (HRs) of UCC risk per standard deviation (SD) of log-transformed nutrient intakes and 95% confidence intervals, adjusted for potential confounders. We investigated associations by tumor subtype, and tested interactions with sex, country of birth, smoking and alcohol drinking. The risk of UCC appeared not to be associated with intake of B-group vitamins or methionine, and findings were consistent across tumor subtypes and across demographic and lifestyle characteristics of the participants. A potential interaction between vitamin B1 and alcohol drinking was observed (all participants: HR per 1 SD = 0.99 (0.91 1.09), never drinkers: HR = 0.81 (0.69-0.97), p-interaction = 0.02), which needs to be confirmed by other studies. Our findings do not indicate that dietary intake of nutrients involved in one-carbon metabolism are associated with UCC risk. PMID- 29446078 TI - A real-time method to simultaneously measure linear energy transfer and dose for proton therapy using organic scintillators. AB - PURPOSE: Currently, no detectors are capable of simultaneously measuring dose and linear energy transfer (LET) in real time. In this study, we evaluated the feasibility of exploiting the difference in the response of various organic plastic scintillation detectors to measure LET and dose in therapeutic proton beams. The hypothesis behind this work was that the ratio of the responses of different scintillators exposed to the same proton beam can be used to obtain a LET vs ratio calibration curve that can then be used to infer LET under any other measurement conditions. METHODS: We first used similar scintillators with different ionization quenching factors. LET values for different irradiation conditions were calculated using a validated Monte Carlo model of the proton beam line. The quenching factors in the Birks equation for different scintillators as a function of LET were obtained from measurements in a 100-MeV pristine proton beam. We then used four different organic scintillation materials - polystyrene (BCF-12), poly (methyl methacrylate), polyvinyltoluene, and a liquid scintillator - for which the LET response varied with regard to not only quenching but also differences in material density and relative stopping power. We simultaneously exposed the four different organic scintillators and a plane-parallel ion chamber to passively scattered proton beams at fluence-averaged LET. Comparisons to the expected values obtained from the Monte Carlo simulations were made on the basis of both dose and LET. RESULTS: The maximum difference in the quenching factor was 20%, resulting in a 5% change in LET with a response ratio over a range of 5 keV/MUm. Among all the scintillators investigated, the ratio of PMMA to BCF-12 provided the best correlation with LET values and was therefore used to construct the LET calibration curve. The expected LET values in the validation set were within 2% +/- 6%, which resulted in dose accuracy of 1.5% +/- 5.8% for the range of LET values investigated in this work. CONCLUSIONS: We demonstrated the feasibility of using the ratio of the light outputs of two organic scintillators to simultaneously measure LET and dose in therapeutic proton beams for fluence averaged LET values from 0.47 to 1.26 keV/MUm. Further studies are needed to verify the response for higher LET values and the reproducibility of this method.

PMID- 29446081 TI - Under the weather?-The direct effects of climate warming on a threatened desert lizard are mediated by their activity phase and burrow system. AB - For ectotherms such as lizards, the importance of behavioural thermoregulation in avoiding thermal extremes is well-established and is increasingly acknowledged in modern studies of climate warming and its impacts. Less appreciated and understood are the buffering roles of retreat sites and activity phase, in part because of logistical challenges of studying below-ground activity. Burrowing and nocturnal activity are key behavioural adaptations that have enabled a diverse range of reptiles to survive extreme environmental temperatures within hot desert regions. Yet, the direct impact of recent global warming on activity potential has been hypothesised to have caused extinctions in desert lizards, including the Australian arid zone skink Liopholis kintorei. We test the relevance of this hypothesis through a detailed characterisation of the above- and below-ground thermal and hydric microclimates available to, and used by, L. kintorei. We integrate operative temperatures with observed body temperatures to construct daily activity budgets, including the inference of subterranean behaviour. We then assess the likelihood that contemporary and future local extinctions in this species, and those of similar burrowing habits, could be explained by the direct effects of warming on its activity budget and exposure to thermal extremes. We found that L. kintorei spent only 4% of its time active on the surface, primarily at dusk, and that overall potential surface activity will be increased, not restricted, with climate warming. The burrow system provides an exceptional buffer to current and future maximum extremes of temperature (~40 degrees C reduction from potential surface temperatures), and desiccation (burrows near 100% humidity). Therefore, any climate warming impacts on this species are likely to be indirect. Our findings reflect the general buffering capacity of underground microclimates, therefore, our conclusions for L. kintorei are more generally applicable to nocturnal and crepuscular ectotherms, and highlight the need to consider the buffering properties of retreat sites and activity phase when forecasting climate change impacts. PMID- 29446082 TI - Development of a dual-energy computed tomography quality control program: Characterization of scanner response and definition of relevant parameters for a fast-kVp switching dual-energy computed tomography system. AB - PURPOSE: A prototype QC phantom system and analysis process were developed to characterize the spectral capabilities of a fast kV-switching dual-energy computed tomography (DECT) scanner. This work addresses the current lack of quantitative oversight for this technology, with the goal of identifying relevant scan parameters and test metrics instrumental to the development of a dual-energy quality control (DEQC). METHODS: A prototype elliptical phantom (effective diameter: 35 cm) was designed with multiple material inserts for DECT imaging. Inserts included tissue equivalent and material rods (including iodine and calcium at varying concentrations). The phantom was scanned on a fast kV switching DECT system using 16 dual-energy acquisitions (CTDIvol range: 10.3-62 mGy) with varying pitch, rotation time, and tube current. The circular head phantom (22 cm diameter) was scanned using a similar protocol (12 acquisitions; CTDIvol range: 36.7-132.6 mGy). All acquisitions were reconstructed at 50, 70, 110, and 140 keV and using a water-iodine material basis pair. The images were evaluated for iodine quantification accuracy, stability of monoenergetic reconstruction CT number, noise, and positional constancy. Variance component analysis was used to identify technique parameters that drove deviations in test metrics. Variances were compared to thresholds derived from manufacturer tolerances to determine technique parameters that had a nominally significant effect on test metrics. RESULTS: Iodine quantification error was largely unaffected by any of the technique parameters investigated. Monoenergetic HU stability was found to be affected by mAs, with a threshold under which spectral separation was unsuccessful, diminishing the utility of DECT imaging. Noise was found to be affected by CTDIvol in the DEQC body phantom, and CTDIvol and mA in the DEQC head phantom. Positional constancy was found to be affected by mAs in the DEQC body phantom and mA in the DEQC head phantom. CONCLUSION: A streamlined scan protocol was developed to further investigate the effects of CTDIvol and rotation time while limiting data collection to the DEQC body phantom. Further data collection will be pursued to determine baseline values and statistically based failure thresholds for the validation of long-term DECT scanner performance. PMID- 29446083 TI - Development and clinical characterization of a novel 2041 liquid-filled ionization chambers array for high-resolution verification of radiotherapy treatments. AB - PURPOSE: The aim of this study was to present a novel 2041 liquid-filled ionization chamber array for high-resolution verification of radiotherapy treatments. MATERIALS AND METHODS: The prototype has 2041 ionization chambers of 2.5 * 2.5 mm2 area filled with isooctane. The detection elements are arranged in a central square grid of 43 * 43, totally covering an area of 107.5 * 107.5 mm2 . The central inline and cross-line are extended to 227 mm and the diagonals to 321 mm to be able to perform profile measurements of large fields. We have studied stability, pixel response uniformity, dose rate dependence, depth and field size dependence and anisotropy. We present results for output factors, tongue-and groove, garden fence, small field profiles, irregular fields, and verification of dose planes of patient treatments. RESULTS: Comparison with other detectors used for small field dosimetry (SFD, CC13, microDiamond) has shown good agreement. Output factors measured with the device for square fields ranging from 10 * 10 to 100 * 100 mm2 showed relative differences within 1%. The response of the detector shows a strong dependence on the angle of incident radiation that needs to be corrected for. On the other hand, inter-pixel relative response variations in the 0.95-1.08 range have been found and corrected for. The application of the device for the verification of dose planes of several treatments has shown gamma passing rates above 97% for tolerances of 2% and 2 mm. The verification of other clinical fields, like small fields and irregular fields used in the commissioning of the TPS, also showed large passing rates. The verification of garden fence and tongue and-groove fields was affected by volume-averaging effects. CONCLUSIONS: The results show that the liquid filled ionization chamber prototype here presented is appropriate for the verification of radiotherapy treatments with high spatial resolution. Recombination effects do not affect very much the verification of relative dose distributions. However, verification of absolute dose distributions may require normalization to a radiation field which is representative of the dose rate of the treatment delivered. PMID- 29446084 TI - An assessment of injection site reaction and injection site pain of 1-month and 3 month long-acting injectable formulations of paliperidone palmitate. AB - PURPOSE: To evaluate injection site reactions and pain following paliperidone palmitate 1-month (PP1M) and 3-month (PP3M) administration using safety data of double-blind (DB), noninferiority study. METHODS: Patients (n = 1,429) with schizophrenia, treated with PP1M (50-150 mg-eq, 17-week open-label [OL] phase) were randomized to PP1M or PP3M in 48-week DB phase. FINDINGS: PP1M and PP3M injections were well tolerated. Incidence of induration, redness, and swelling were low in both phases (OL: 9-12%; DB: 7-13%), and were mostly mild in both groups. Mean (SD) visual analog scale scores decreased from OL-baseline (22.0 [21.6]) to DB-baseline (19.5 [20.6] vs. 18.4 [20.4]) and DB-endpoint (15.6 [17.9] vs. 15.5 [18.3]). PRACTICE IMPLICATIONS: Injection site reactions and pain were low and similar between both treatments, regardless of administration site and dose. PMID- 29446085 TI - DR4 mediates the progression, invasion, metastasis and survival of colorectal cancer through the Sp1/NF1 switch axis on genomic locus. AB - The single nucleotide polymorphism (SNP), -397G > T (rs13278062) polymorphism, in the promoter of Death Receptor 4 (DR4) had been reported to be associated with a significantly increased risk for bladder cancer. However, the association of this SNP with the risk of colorectal cancer has not been reported. In this study, we performed a case-control study in 1,078 colorectal cancer patients and 1,175 matched healthy controls to evaluate the association of the potential functional genetic variants in DR4 with risk and survival of colorectal cancer. PCR-TaqMan were used to genotype the rs13278062, rs1000294 and rs2235126 polymorphisms. We found that subjects carrying the rs13278062 GT/TT genotypes had a significantly lower risk and increased survival time when compared to the GG genotype. We also constructed the rs13278062 GT/TT genotype in SW480 and SW620 cells (rs13278062 is GG in both cell lines) with the CRISPR/Cas9 system. Flow cytometry experiments showed that the rs13278062 TT genotype promoted apoptosis in colorectal cancer cells. In vitro and in vivo experiments established that the rs13278062 G to T mutation inhibited carcinogenesis and metastasis of colorectal cancer. Chromatin immunoprecipitation (ChIP) assays revealed that the rs13278062 G > T polymorphism altered the binding affinity of the transcription factors Sp1/NF1 to the rs13278062 mutation region. Immunohistochemistry, western blot, and qPCR corroborated that the rs13278062 GT/TT genotypes increased the expression of DR4 protein in colorectal cancer tissues and cells. In conclusion, these findings indicate that DR4 mediated progression, invasion, metastasis and survival of colorectal cancer via the Sp1/NF1 switch axis on genomics locus. PMID- 29446086 TI - Subchondral bone morphology in the metacarpus of racehorses in training changes with distance from the articular surface but not with age. AB - The repetitive large loads generated during high-speed training and racing commonly cause subchondral bone injuries in the metacarpal condyles of racehorses. Adaptive bone modelling leads to focal sclerosis at the site of highest loading in the palmar aspect of the metacarpal condyles. Information on whether and how adaptive modelling of subchondral bone changes during the career of a racehorse is sparse. The aim of this cross-sectional study was to describe the changes in subchondral bone micromorphology in the area of highest loading in the palmar aspect of the metacarpal condyle in thoroughbred racehorses as a function of age and training. Bone morphology parameters derived from micro-CT images were evaluated using principal component analysis and mixed-effects linear regression models. The largest differences in micromorphology were observed in untrained horses between the age of 16 and 20 months. Age and duration of a training period had no influence on tissue mineral density, bone volume fraction or number and area of closed pores to a depth of 5.1 mm from the articular surface in 2- to 4-year-old racehorses in training. Horses with subchondral bone injuries had more pores in cross-section compared with horses without subchondral bone injuries. Differences in bone volume fraction were due to the volume of less mineralised bone. Tissue mineral density increased and bone volume fraction decreased with increasing distance from the articular surface up to 5.1 mm from the articular surface. Further research is required to elucidate the biomechanical and pathophysiological consequences of these gradients of micromorphological parameters in the subchondral bone.

PMID- 29446089 TI - Morphometric and histopathological evaluation of the effect of grape seed proanthocyanidin on alveolar bone loss in experimental diabetes and periodontitis. AB - OBJECTIVE: Grape seed proanthocyanidine extract (GSPE) is a strong antioxidant derived from the grape seeds (Vitis vinifera, Terral J.F.) and has a polyphenolic structure with a wide range of biological activity. The aim of the present study was to evaluate the effects of GSPE on alveolar bone loss and histopathological changes in rats with diabetes mellitus and ligature-induced periodontitis. MATERIAL AND METHODS: Forty rats were divided into 6 study groups. Control (C, 6 rats) group, periodontitis (P, 6 rats) group, diabetes (D, 6 rats) group, diabetes and periodontitis (D+P, 6 rats) group, diabetes, periodontitis and 100 mg/kg/day GSPE (GSPE-100, 8 rats), and diabetes, periodontitis and 200 mg/kg/day GSPE (GSPE-200, 8 rats) group. Diabetes mellitus was induced by intraperitoneal injection of a single dose of streptozotocin (60 mg/kg). Periodontitis was induced via ligation method. Silk ligatures were placed at the mandibular right first molars. GSPE was administered by oral gavage. After 30 days, all rats were killed. Alveolar bone loss was measured morphometrically via a stereomicroscope. For histopathological analyses, Alizarin red staining, and matrix metalloproteinase (MMP)-8, vascular endothelial growth factor and hypoxia inducible factor (HIF)-1alpha immunohistochemistry were performed. Tartrate resistant acid phosphatase-positive osteoclast cells and relative total inflammatory cells were also determined. RESULTS: The highest alveolar bone loss was observed in the D+P group (P < .05). GSP-200 group decreased alveolar bone loss (P < .05). The D+P group had the highest osteoclast counts, but the difference was not significant compared to the P, GSPE-100 and GSPE-200 groups (P > .05). The inflammation in the D+P group was also higher than the other groups (P < .05). The osteoblast numbers increased in the GSPE-100 and GSPE-200 groups compared to the P and D+P groups (P < .05). MMP-8 and HIF-1alpha levels were highest in the D+P group and GSPE significantly decreased these levels (P < .05). CONCLUSION: Within the limits of this animal study, it can be suggested that GSPE administration may decrease periodontal inflammation and alveolar bone loss via decreasing MMP-8 and HIF-1alpha levels and increase osteoblastic activity in diabetic rats with experimental periodontitis. PMID- 29446090 TI - Potential lives saved in 73 countries by adopting multi-cohort vaccination of 9 14-year-old girls against human papillomavirus. AB - Up to 2016, low- and middle-income countries mostly introduced routine human papillomavirus (HPV) vaccination for just a single age-cohort of girls each year. However, high-income countries have reported large reductions in HPV prevalence following "catch-up" vaccination of multiple age-cohorts in the year of HPV vaccine introduction. We used the mathematical model PRIME to project the incremental impact of vaccinating 10- to 14-year-old girls compared to routine HPV vaccination only in the same year that routine vaccination is expected to be introduced for 9-year-old girls across 73 low- and lower-middle-income countries. Adding multiple age-cohort vaccination could increase the number of cervical cancer deaths averted by vaccine introductions in 2015-2030 by 30-40% or an additional 1.23-1.79 million over the lifetime of the vaccinated cohorts. The number of girls needed to vaccinate to prevent one death is 101 in the most pessimistic scenario, which is only slightly greater than that for routine vaccination of 9-year-old girls (87). These results hold even when assuming that girls who have sexually debuted do not benefit from vaccination. Results suggest that multiple age-cohort vaccination of 9- to 14-year-old girls could accelerate HPV vaccine impact and be cost-effective. PMID- 29446091 TI - An evaluation of delay to reinforcement and mand variability during functional communication training. AB - Children with autism spectrum disorder and other developmental disabilities often exhibit invariant responding (i.e., restricted behavioral repertoires), deficits in communication, and challenging behavior. Approaches demonstrated in the basic and applied literature to increase response variability include extinction, lag schedules of reinforcement, and percentile schedules of reinforcement. Results of basic studies have also indicated that delays to reinforcement often produce increases in response variability. The purpose of the current study was to evaluate the effects of a delay to reinforcement on the variability of communication responses during functional communication training with individuals with developmental disabilities and histories of engaging in challenging behavior. Results indicated that delays to reinforcement increased mand variability with all four participants with variable effects on challenging behavior across participants. PMID- 29446088 TI - The Second Visual System of The Tree Shrew. AB - This review provides a historical account of the discovery of secondary visual pathways (from retina to the superior colliculus to the dorsal thalamus and extrastriate cortex), and Vivien Casagrande's pioneering studies of this system using the tree shrew as a model. Subsequent studies of visual pathways in the tree shrew are also reviewed, beginning with a description of the organization and central projections of the tree shrew retina. The organization and connectivity of second visual system components that include the retino-recipient superior colliculus, tecto-recipient pulvinar nucleus and its projections, and the tecto-recipient dorsal lateral geniculate nucleus and its projections are detailed. Potential functions of the second visual system are discussed in the context of this work and in the context of the behavioral studies that initially inspired the secondary visual system concept. PMID- 29446092 TI - Association of salivary lactate dehydrogenase level with systemic inflammation in a Japanese population. AB - BACKGROUND AND OBJECTIVE: Salivary lactate dehydrogenase (LDH) was reported to be a useful parameter for the screening of periodontal disease. We performed a cross sectional study to verify the usefulness of salivary LDH as a biomarker of periodontitis and to investigate the association of severity of periodontitis with systemic inflammation by measuring salivary LDH and serum high sensitive C reactive protein (hs-CRP) levels in a community-based middle-aged and elderly population in Japan. MATERIAL AND METHODS: We recruited 644 men and 1171 women, aged 30-79 years, who participated in the Toon Health Study during 2011-15. Periodontal condition was assessed by full-mouth examination including mean value of probing depth, percentage of probing depth of >=4 mm and >=6 mm, and bleeding on probing. Saliva and blood serum samples were collected for measurement of salivary LDH level and hs-CRP, respectively. A linear trend across quartiles of salivary LDH was calculated using linear regression. Interaction of salivary LDH and overweight status (body mass index of >=25 kg/m2 ) was tested using the cross product term of log-transformed continuous salivary LDH and overweight status. RESULTS: Analysis of covariance adjusted for potential confounders revealed strong associations between salivary LDH level and the indicators of periodontal condition (P < .01) in both men and women. Sex- and age-adjusted mean values of hs-CRP according to salivary LDH quartiles were 0.40, 0.45, 0.45 and 0.50 mg/L (P for trend <.01). Although the association was attenuated after further adjustment for body mass index, hypertension, diabetes mellitus, dyslipidemia, alcohol intake, smoking status and physical activity. When stratified by overweight status, the association remained significant in overweight individuals (P = .03). The multivariable adjusted odds ratio of hs-CRP level of >=1 mg/L for the highest vs lowest quartile of salivary LDH was 1.93 (95% CI, 1.01-3.69) in overweight individuals, but not significant in non-overweight individuals. CONCLUSION: Salivary LDH appears to be a promising biomarker for the mass screening of periodontitis in local community health settings. High salivary LDH levels, particularly in overweight individuals might contribute to prevention of cardiovascular disease, through measuring systemic inflammatory burdens as well as traditional cardiovascular risk factors. PMID- 29446093 TI - Effects of neutral and enthusiastic praise on the rate of discrimination acquisition. AB - Previous research has shown that praise is an effective reinforcer; however, few researchers have evaluated whether qualitative differences in praise affect responding. The purpose of the current study was to compare the effects of neutral, enthusiastic, and no praise on the rate of matching-to-sample acquisition during discrete-trial training with adults diagnosed with autism and an intellectual disability. In addition, we evaluated preference for neutral, enthusiastic, and no praise. All three participants acquired responses slightly faster during the enthusiastic praise condition. Preference assessment results showed that one participant preferred enthusiastic praise, whereas the two other participants showed indiscriminate selections. PMID- 29446094 TI - Experimental evidence that density mediates negative frequency-dependent selection on aggression. AB - Aggression can be beneficial in competitive environments if aggressive individuals are more likely to access resources than non-aggressive individuals. However, variation in aggressive behaviour persists within populations, suggesting that high levels of aggression might not always be favoured. The goal of this study was to experimentally assess the effects of population density and phenotypic frequency on selection on aggression in a competitive environment. We compared survival of two strains of Drosophila melanogaster that differ in aggression across three density treatments and five frequency treatments (single strain groups, equal numbers of each strain and strains mixed at 3:1 and 1:3 ratios) during a period of limited resources. While there was no difference in survival across single-strain treatments, survival was strongly density dependent, with declining survival as density increased. Furthermore, at medium and high densities, there was evidence of negative frequency-dependent selection, where rare strains experienced greater survival than common strains. However, there was no evidence of negative frequency-dependent selection at low density. Our results indicate that the benefits of aggression during periods of limited resources can depend on the interaction between the phenotypic composition of populations and population density, both of which are mechanisms that could maintain variation in aggressive behaviours within natural populations. PMID- 29446095 TI - Orobanche cernua Loefling Attenuates Ultraviolet B-mediated Photoaging in Human Dermal Fibroblasts. AB - UV radiation is the primary cause of skin photoaging, which results in an increase in matrix metalloproteinases and degradation of collagen. Developing new natural antioxidant as photoprotective agents has become a popular area of research. Orobanche cernua Loefling is a parasitic plant that is rich in phenylethanoid glycosides (PhGs). This study investigated the photoprotective effects of the ethanolic extract of Orobanche cernua Loefling (OC) and its principal component acteoside on UVB-induced photoaging as well as their underlying molecular mechanisms in normal human dermal fibroblasts (NHDFs). Biological testing demonstrated that OC and acteoside possessed significant photoprotective activities, reducing MMP and IL-6 levels while improving type-I procollagen synthesis in UVB-irradiated NHDFs. Further study showed that the protective mechanisms were the improvement of transcription factor Nrf2-mediated antioxidant defensive system, suppression of MAPK/AP-1 and activation of the TGF beta/Smad pathway. Together, our results suggested that OC might be a promising antiphotoaging agent against UV radiation-induced skin damage. PMID- 29446096 TI - Degradation pattern of a porcine collagen membrane in an in vivo model of guided bone regeneration. AB - BACKGROUND AND OBJECTIVE: Although collagen membranes have been clinically applied for guided tissue/bone regeneration for more than 30 years, their in vivo degradation pattern has never been fully clarified. A better understanding of the different stages of in vivo degradation of collagen membranes is extremely important, considering that the biology of bone regeneration requires the presence of a stable and cell/tissue-occlusive barrier during the healing stages in order to ensure a predictable result. Therefore, the aim of this study was to investigate the degradation pattern of a porcine non-cross-linked collagen membrane in an in vivo model of guided bone regeneration (GBR). MATERIAL AND METHODS: Decalcified and paraffin-embedded specimens from calvarial defects of 18, 10-month-old Wistar rats were used. The defects were treated with a double layer of collagen membrane and a deproteinized bovine bone mineral particulate graft. At 7, 14 and 30 days of healing, qualitative evaluation with scanning electron microscopy and atomic force microscopy, and histomorphometric measurements were performed. Markers of collagenase activity and bone formation were investigated using an immunofluorescence technique. RESULTS: A significant reduction of membrane thickness was observed from 7 to 30 days of healing, which was associated with progressive loss of collagen alignment, increased collagen remodeling and progressive invasion of woven bone inside the membranes. A limited inflammatory infiltrate was observed at all time points of healing. CONCLUSION: The collagen membrane investigated was biocompatible and able to promote bone regeneration. However, pronounced signs of degradation were observed starting from day 30. Since successful regeneration is obtained only when cell occlusion and space maintenance exist for the healing time needed by the bone progenitor cells to repopulate the defect, the suitability of collagen membranes in cases where long-lasting barriers are needed needs to be further reviewed. PMID- 29446097 TI - Three-dimensional reciprocal space x-ray coherent scattering tomography of two dimensional object. AB - PURPOSE: X-ray coherent scattering tomography is a powerful tool in discriminating biological tissues and bio-compatible materials. Conventional x ray scattering tomography framework can only resolve isotropic scattering profile under the assumption that the material is amorphous or in powder form, which is not true especially for biological samples with orientation-dependent structure. Previous tomography schemes based on x-ray coherent scattering failed to preserve the scattering pattern from samples with preferred orientations, or required elaborated data acquisition scheme, which could limit its application in practical settings. Here, we demonstrate a simple imaging modality to preserve the anisotropic scattering signal in three-dimensional reciprocal (momentum transfer) space of a two-dimensional sample layer. METHODS: By incorporating detector movement along the direction of x-ray beam, combined with a tomographic data acquisition scheme, we match the five dimensions of the measurements with the five dimensions (three in momentum transfer domain, and two in spatial domain) of the object. We employed a collimated pencil beam of a table-top copper anode x-ray tube, along with a panel detector to investigate the feasibility of our method. RESULTS: We have demonstrated x-ray coherent scattering tomographic imaging at a spatial resolution ~2 mm and momentum transfer resolution 0.01 A-1 for the rotation-invariant scattering direction. For any arbitrary, non-rotation invariant direction, the same spatial and momentum transfer resolution can be achieved based on the spatial information from the rotation-invariant direction. The reconstructed scattering profile of each pixel from the experiment is consistent with the x-ray diffraction profile of each material. The three dimensional scattering pattern recovered from the measurement reveals the partially ordered molecular structure of Teflon wrap in our sample. CONCLUSIONS: We extend the applicability of conventional x-ray coherent scattering tomography to the reconstruction of two-dimensional samples with anisotropic scattering profile by introducing additional degree of freedom on the detector. The presented method has the potential to achieve low-cost, high-specificity material discrimination based on x-ray coherent scattering. PMID- 29446098 TI - Safety, efficacy and pharmacokinetics of vedolizumab in patients with simultaneous exposure to an anti-tumour necrosis factor. AB - BACKGROUND: Data on combination-biologic treatment in (IBD) are still scant. AIM: To explore outcomes of patients co-exposed to anti-TNF and vedolizumab. METHODS: Patients starting vedolizumab having measurable anti-TNF levels after recently stopping adalimumab/infliximab ('VDZ-aTNF' group), were compared with control vedolizumab patients in a retrospective 1:2 matched case-control study. RESULTS: Seventy-five patients were included (25 VDZ-aTNF, 50 VDZ). Adverse events were experienced by 9/25 VDZ-aTNF compared to 13/50 VDZ patients (P = 0.4, follow-up 14 weeks in all). Week 14 clinical remission was attained in 10/25 (40%) of VDZ aTNF patients versus 23/50 (46%) of VDZ patients (OR = 0.8, 95% CI 0.3-2.1, P = 0.6) and clinical response in 19/25 (76%) versus 39/50 (78%) respectively (OR = 0.9, 95% CI 0.3-2.7, P = 0.8). Corticosteroid-free remission and corticosteroid free response were experienced by 30% and 54%, respectively, of the entire cohort, and were similar between the two groups. Vedolizumab drug concentrations at week 2, 6 and 14 were similar among VDZ-aTNF and VDZ patients (P > 0.5). Multi variable analysis showed independent association of some vedolizumab drug-levels time-points with baseline albumin and weight, but not with anti-TNF co-exposure. In a prospective study of a separate cohort of patients starting infliximab (n = 12), the percentage of alpha4beta7+ memory T cells, slightly but nonsignificantly increased throughout weeks 0, 2 to 14 (26 +/- 2.3%, 27.8 +/- 2.9%, 29.5 +/- 2.6% respectively, P = 0.06). CONCLUSIONS: Vedolizumab/anti-TNF co-exposure did not generate new safety signals during 14-weeks induction, nor did it reduce efficacy or alter vedolizumab pharmacokinetics. These observations may aid the design of future co-biologics trials and also suggest that a deliberate waiting-interval between anti-TNF cessation and subsequent vedolizumab initiation may not be warranted.

AB - : Bacterial wilt of Curcuma alismatifolia (Patumma) caused by Ralstonia solanacearum is a major disease affecting the quality of rhizome exports. Traditionally, R. solanacearum is classified into five races based on differences in host range and six biovars based on biochemical properties. Recently a classification scheme based on phylotypes and sequevars was presented by the scientific community as a tool for determining phylogenetic relationships within R. solanacearum. This study used traditional and molecular methods to identify R. solanacearum strains from Patumma. All the strains were identified as biovar 4. A phylotype-specific multiplex PCR-based phylotyping of all the isolates detected the phylotype I-specific amplicon of 144 bp and the R. solanacearum-specific 281 bp amplicon. Phylogenetic analyses of endoglucanase (egl) sequences clustered all three strains of Patumma into phylotype I, sequevar 48 with reference strains M2 and M6. The study determined that the R. solanacearum strains from Patumma belong to biovar 4, phylotype I that originated from Asia, and sequevar 48. SIGNIFICANCE AND IMPACT OF THE STUDY: Phylotype and sequevar of Ralstonia solanacearum were associated with geographic region and geographic distribution. This is the first study to identify phylotype and sequevar of R. solanacearum from Patumma in Chiang Mai, Thailand. This will be useful for study of disease epidemiology and could help management for control of bacterial wilt diseases in this host. PMID- 29446104 TI - Heparin mimetics with anticoagulant activity. AB - Heparin, a sulfated polysaccharide belonging to the glycosaminoglycan family, has been widely used as an anticoagulant drug for decades and remains the most commonly used parenteral anticoagulant in adults and children. However, heparin has important clinical limitations and is derived from animal sources which pose significant safety and supply problems. The ever growing shortage of the raw material for heparin manufacturing may become a very significant issue in the future. These global limitations have prompted much research, especially following the recent well-publicized contamination scandal, into the development of alternative anticoagulants derived from non-animal and/or totally synthetic sources that mimic the structural features and properties of heparin. Such compounds, termed heparin mimetics, are also needed as anticoagulant materials for use in biomedical applications (e.g., stents, grafts, implants etc.). This review encompasses the development of heparin mimetics of various structural classes, including synthetic polymers and non-carbohydrate small molecules as well as sulfated oligo- and polysaccharides, and fondaparinux derivatives and conjugates, with a focus on developments in the past 10 years. PMID- 29446103 TI - Carfilzomib in relapsed or refractory multiple myeloma patients with early or late relapse following prior therapy: A subgroup analysis of the randomized phase 3 ASPIRE and ENDEAVOR trials. AB - We performed analyses of the randomized phase 3 ASPIRE and ENDEAVOR trials to investigate the efficacy of carfilzomib among subgroups of relapsed or refractory multiple myeloma patients who had early or late disease relapse following initiation of the immediately prior therapy. In ASPIRE and ENDEAVOR, patients had received 1 to 3 prior lines of therapy. Patients in ASPIRE received carfilzomib, lenalidomide, and dexamethasone (KRd) or lenalidomide and dexamethasone (Rd), and patients in ENDEAVOR received carfilzomib and dexamethasone (Kd) or bortezomib and dexamethasone (Vd). Patients with relapse <=1 year after initiating the most recent prior line of therapy were categorized as early relapsers, and patients with relapse after >1 year were categorized as late relapsers. The median progression-free survival (PFS) in ASPIRE for early relapsers was 21.4 months for KRd vs 10.7 months for Rd (hazard ratio [HR]: 0.714; 95% confidence interval [CI]: 0.508-1.004; P = 0.0257), and for late relapsers was 29.7 months for KRd vs 18.2 months for Rd (HR: 0.675; 95% CI: 0.533-0.854; P = 0.0005). The overall response rate (ORR) for early relapsers was 83.2% for KRd vs 54.8% for Rd, and for late relapsers was 89.0% for KRd vs 69.7% for Rd. The median PFS in ENDEAVOR (Kd vs Vd) for early relapsers was 13.9 months vs 5.7 months (HR: 0.598; 95% CI: 0.423-0.846; P = 0.0017), and for late relapsers was 22.2 months vs 10.2 months (HR: 0.486; 95% CI: 0.382-0.620; P < 0.0001). The ORR (Kd vs Vd) for early relapsers was 63.4% vs 49.1% and for late relapsers was 81.8% vs 66.8%. In conclusion, patients with relapsed or refractory multiple myeloma who received carfilzomib-containing regimens had improved PFS and ORR compared with control groups, regardless of whether they had an early or late relapse following the most recent prior therapy.

PMID- 29446106 TI - Impact of controlled attenuation parameter on detecting fibrosis using liver stiffness measurement. AB - BACKGROUND: Liver fibrosis is often accompanied by steatosis, particularly in patients with non-alcoholic fatty liver disease (NAFLD), and its non-invasive characterisation is of utmost importance. Vibration-controlled transient elastography is the non-invasive method of choice; however, recent research suggests that steatosis may influence its diagnostic performance. Controlled Attenuation Parameter (CAP) added to transient elastography enables simultaneous assessment of steatosis and fibrosis. AIM: To determine how to use CAP in interpreting liver stiffness measurements. METHODS: This is a secondary analysis of data from an individual patient data meta-analysis on CAP. The main exclusion criteria for the current analysis were unknown aetiology, unreliable elastography measurement and data already used for the same research question. Aetiology specific liver stiffness measurement cut-offs were determined and used to estimate positive and negative predictive values (PPV/NPV) with logistic regression as functions of CAP. RESULTS: Two thousand and fifty eight patients fulfilled the inclusion criteria (37% women, 18% NAFLD/NASH, 42% HBV, 40% HCV, 51% significant fibrosis >= F2). Youden optimised cut-offs were only sufficient for ruling out cirrhosis (NPV of 98%). With sensitivity and specificity-optimised cut-offs, NPV for ruling out significant fibrosis was moderate (70%) and could be improved slightly through consideration of CAP. PPV for significant fibrosis and cirrhosis were 68% and 55% respectively, despite specificity-optimised cut-offs for cirrhosis. CONCLUSIONS: Liver stiffness measurement values below aetiology specific cut-offs are very useful for ruling out cirrhosis, and to a lesser extent for ruling out significant fibrosis. In the case of the latter, Controlled Attenuation Parameter can improve interpretation slightly. Even if cut-offs are very high, liver stiffness measurements are not very reliable for ruling in fibrosis or cirrhosis. PMID- 29446107 TI - Intestinal T-cell lymphoma with enteropathy-associated T-cell lymphoma-like features arising in the setting of adult autoimmune enteropathy. AB - Enteropathy-associated T-cell lymphoma is regarded as a dismal, late complication of coeliac disease, though a single case of T-cell lymphoma with such features arising in the setting of autoimmune enteropathy of the adult has been reported to date. We aim to describe the case of a 41-year-old woman complaining of severe malabsorption syndrome, who was diagnosed with autoimmune enteropathy based on the presence of flat intestinal mucosa unresponsive to any dietary restriction and positivity for enterocyte autoantibodies. Steroid therapy led to a complete recovery of both mucosal and clinical findings over 12 years, when disease relapse was accompanied by the appearance of monoclonal rearrangement of T-cell receptor-gamma and peculiar T-cell phenotypic abnormalities, leading to a rapid transition to an overt T-cell lymphoma with features of the enteropathy associated subtype. Despite intensive treatment, the patient developed cerebral metastasis and died 9 months later. Our case enhances the concept of enteropathy associated T-cell lymphoma as a disease that may arise in the setting of enteropathies other than coeliac disease, thus representing a heterogeneous entity. Moreover, our observations support the need of a close follow-up of these patients, coupled with comprehensive characterization of mucosal biopsies. PMID- 29446108 TI - Resilience Analysis of a Remote Offshore Oil and Gas Facility for a Potential Hydrocarbon Release. AB - Resilience is the capability of a system to adjust its functionality during a disturbance or perturbation. The present work attempts to quantify resilience as a function of reliability, vulnerability, and maintainability. The approach assesses proactive and reactive defense mechanisms along with operational factors to respond to unwanted disturbances and perturbation. This article employs a Bayesian network format to build a resilience model. The application of the model is tested on hydrocarbon-release scenarios during an offloading operation in a remote and harsh environment. The model identifies requirements for robust recovery and adaptability during an unplanned scenario related to a hydrocarbon release. This study attempts to relate the resilience capacity of a system to the system's absorptive, adaptive, and restorative capacities. These factors influence predisaster and postdisaster strategies that can be mapped to enhance the resilience of the system. PMID- 29446109 TI - Systematic review: the natural history of alpha-1 antitrypsin deficiency, and associated liver disease. AB - BACKGROUND: Alpha-1 antitrypsin deficiency (AATD) is estimated to affect three million people worldwide. It causes liver disease in a proportion of carriers of the PiS and PiZ allele due to the formation and retention of polymers within the endoplasmic reticulum of hepatocytes. The reason for this selective penetrance is not known. Although clinical trials are underway, liver transplantation is the only effective treatment for liver disease due to AATD. AIMS: To report the prevalence and natural history of liver disease among individuals with AATD, and assess the outcomes of liver transplantation through systematic review. METHODS: A comprehensive search was conducted across multiple databases. Two independent authors selected the articles and assessed bias using the Newcastle-Ottawa Scale. Data were pooled for analysis, where comparable outcomes were reported. RESULTS: Thirty-five studies were identified related to disease progression and 12 for the treatment of AATD. Seven per cent of children were reported to develop liver cirrhosis, with 16.5% of individuals presenting in childhood requiring liver transplantation. Of those surviving to adulthood, 10.5% had liver cirrhosis and 14.7% required transplantation. Liver transplantation was the only effective treatment reported and outcomes compare favourably to other indications, with 5 year survival reported as over 90% in children and over 80% in adults. DISCUSSION: The clinical course of liver disease in individuals with AATD remains poorly understood, but affects about 10% of those with AATD. More research is required to identify those patients at risk of developing liver disease at an early stage, and to provide alternative treatments to liver transplantation.

AB - Previous research has shown that men and women, on average, have different risk attitudes and may therefore see different value propositions in response to new opportunities. We use data from smallholder farm households in Mali to test whether risk perceptions differ by gender and across domains. We model this potential association across six risks (work injury, extreme weather, community relationships, debt, lack of buyers, and conflict) while controlling for demographic and attitudinal characteristics. Factor analysis highlights extreme weather and conflict as eliciting the most distinct patterns of participant response. Regression analysis for Mali as a whole reveals an association between gender and risk perception, with women expressing more concern except in the extreme weather domain; however, the association with gender is largely absent when models control for geographic region. We also find lower risk perception associated with an individualistic and/or fatalistic worldview, a risk-tolerant outlook, and optimism about the future, while education, better health, a social orientation, self-efficacy, and access to information are generally associated with more frequent worry-with some inconsistency. Income, wealth, and time poverty exhibit complex associations with perception of risk. Understanding whether and how men's and women's risk preferences differ, and identifying other dominant predictors such as geographic region and worldview, could help development organizations to shape risk mitigation interventions to increase the likelihood of adoption, and to avoid inadvertently making certain subpopulations worse off by increasing the potential for negative outcomes. PMID- 29446113 TI - Use of a Simple, Inexpensive Dual-Modality Phantom as a Learning Tool for Magnetic Resonance Imaging-Ultrasound Fusion Techniques. AB - We describe an easily constructed, customizable phantom for magnetic resonance imaging-ultrasound fusion imaging and demonstrate its role as a learning tool to initiate clinical use of this emerging modality. Magnetic resonance imaging ultrasound fusion can prove unwieldy to integrate into routine practice. We demonstrate real-time fusion with single-sequence magnetic resonance imaging uploaded to the ultrasound console. Phantom training sessions allow radiologists and sonographers to practice fiducial marker selection and improve efficiency with the fusion hardware and software interfaces. Such a tool is useful when the modality is first introduced to a practice and in settings of sporadic use, in which intermittent training may be useful.

PMID- 29446115 TI - Iatrogenic risk factors associated with hospital readmission of elderly patients: A matched case-control study using a clinical data warehouse. AB - WHAT IS KNOWN: Hospital readmission within 30 days of patient discharge has become a standard to judge the quality of hospitalizations. It is estimated that 14% of the elderly, people over 75 years old or those over 65 with comorbidities, are at risk of readmission, of which 23% are avoidable. It may be possible to identify elderly patients at risk of readmission and implement steps to reduce avoidable readmissions. OBJECTIVE: The aim of this study was to identify iatrogenic risk factors for readmission. The secondary objective was to evaluate the rate of drug-related readmissions (DRRs) among all readmissions and compare it to the rate of readmissions for other reasons. METHODS: We conducted a retrospective, matched, case-control study to identify non-demographic risk factors for avoidable readmission, specifically DRRs. The study included patients hospitalized between 1 September 2014 and 31 October 2015 in an 800-bed university hospital. We included patients aged 75 and over. Cases consisted of patients readmitted to the emergency department within 30 days of initial discharge. Controls did not return to the emergency department within 30 days. Cases and controls were matched on sex and age because they are known as readmissions risk factors. After comparison of the mean or percentage between cases and controls for each variable, we conducted a conditional logistic regression. RESULTS: The risk factors identified were an emergency admission at the index hospitalization, returning home after discharge, a history of unplanned readmissions and prescription of nervous system drugs. Otherwise, 11.4% of the readmissions were DRRs, of which 30% were caused by an overdose of antihypertensive. The number of drugs at readmission was higher, and potentially inappropriate medications were more widely prescribed for DRRs than for readmissions for other reasons. WHAT IS NEW AND CONCLUSION: In this matched case control retrospective study, after controlling for gender and age, we identified the typical profile of elderly patients at risk of readmission. These patients had an unplanned admission at the index hospitalization and prescribed nervous system drugs at discharge from the index admission; they have a history of unplanned readmission within 30 days and return home after discharge. PMID- 29446116 TI - Does integrated academic and health education prevent substance use? Systematic review and meta-analyses. AB - BACKGROUND: Prevention of substance (alcohol, tobacco, illegal/legal drug) use in adolescents is a public health priority. As the scope for school-based health education is constrained in school timetables, interventions integrating academic and health education have gained traction in the UK and elsewhere, though evidence for their effectiveness remains unclear. We sought to synthesize the effectiveness of interventions integrating academic and health education for the prevention of substance use. METHODS: We searched 19 databases between November and December 2015, among other methods. We included randomized trials of interventions integrating academic and health education targeting school students aged 4-18 and reporting substance use outcomes. We excluded interventions for specific health-related subpopulations (e.g., children with behavioural difficulties). Data were extracted independently in duplicate. Outcomes were synthesized by school key stage (KS) using multilevel meta-analyses, for substance use, overall and by type. RESULTS: We identified 7 trials reporting substance use. Interventions reduced substance use generally in years 7-9 (KS3) based on 5 evaluations (d = -0.09, 95% CI [-0.17, -0.01], I2 = 35%), as well as in years 10-11 (KS4) based on 3 evaluations (-0.06, [-0.09, -0.02]; I2 = 0%). Interventions were broadly effective for reducing specific alcohol, tobacco, and drug use in both KS groups. CONCLUSIONS: Evidence quality was highly variable. Findings for years 3-6 and 12-13 could not be meta-analysed, and we could not assess publication bias. Interventions appear to have a small but significant effect reducing substance use. Specific methods of integrating academic and health education remain poorly understood. PMID- 29446118 TI - Water suppression in the human brain with hypergeometric RF pulses for single voxel and multi-voxel MR spectroscopy. AB - PURPOSE: To develop and investigate a novel water suppression sequence with hypergeometric pulses at 3 T. METHODS: Simulations were used to optimize the delays and amplitudes of 5 hypergeometric prepulses, to minimize the residual water over a range of T1 and B1 values. Single-voxel data with hypergeometric water suppression (HGWS) prepulses were acquired in the centrum semiovale, 2 parietal regions, and insula of 7 subjects, and compared with VAPOR water suppression. Magnetic resonance spectroscopic imaging (MRSI) data using both VAPOR and HGWS prepulses were also collected and compared. Water suppression performance was calculated as the residual water peak height relative to the unsuppressed water peak. MRSI voxel-by-voxel comparison was performed by calculating the ratio between HGWS and VAPOR residual water peaks. RESULTS: In simulations, HGWS and VAPOR are insensitive to B1 and water T1 variations, but with no B1 variation, HGWS has a lower average residual water fraction (0.0033) than that of VAPOR (0.0091). In single-voxel acquisitions, HGWS performs better than VAPOR in all regions with a 2.3-fold to 5.7-fold lower residual water. In MRSI acquisitions, HGWS performs on average 2.3-fold better than VAPOR in 98.9% of the voxels. CONCLUSION: HGWS provides better water suppression than VAPOR in both single-voxel and multivoxel acquisitions with a shorter sequence duration. PMID- 29446119 TI - Pancreaticoduodenal arterial arcades: Their dominance and variations-their potential clinical relevance. AB - The complex arterial system makes pancreatic interventions technically challenging for surgeons, and interventional radiologists. The arterial variants may alter tumor resecability, and cause complications in arterial embolization. International data on pancreatic blood supply are variable; therefore, we aimed to determine the frequency of variants of pancreaticoduodenal (PD) arterial arcades. Arteries of human abdominal organ complexes (50) were injected with resin mixture, and then corroded. CT scans and three-dimensional reconstructions were made; diameters of arcades were measured. Two PD arcades were found in 58%, three arcades in 30%, one arcade in three cases, four arcade in one specimen, and five arcades in two cases. In the casts with two arches the average diameter was 1.472 +/- 0.432 mm on the anterior and 1.383 +/- 0.343 mm on the posterior arch. Assessing the dominance of the PD arcades, the anterior arch proved to be dominant in 52% of the cases, and in 35% the posterior one by the criterion of 25% cross-section difference. It is advised to analyze the variations and dominance on a CT/MR-angiography before local chemotherapy. Furthermore, to reveal the arterial variations, a preoperative CT/MR-angiography would provide faster recuperation and better postoperative life quality. Clin. Anat. 31:544 550, 2018.

PMID- 29446117 TI - The sociology of cancer: a decade of research. AB - Biomedicine is often presented as the driving force behind improvements in cancer care, with genomics the latest innovation poised to change the meaning, diagnosis, treatment, prevention and lived experience of cancer. Reviewing sociological analyses of a diversity of patient and practitioner experiences and accounts of cancer during the last decade (2007-17), we explore the experiences of, approaches to and understandings of cancer in this period. We identify three key areas of focus: (i) cancer patient experiences and identities; (ii) cancer risk and responsibilities and (iii) bioclinical collectives. We explore these sociological studies of societal and biomedical developments and how sociologists have sought to influence developments in cancer identities, care and research. We end by suggesting that we extend our understanding of innovations in the fields of cancer research to take better account of these wider social and cultural innovations, together with patients, activists' and sociologists' contributions therein. PMID- 29446121 TI - Atrophy of hip abductor muscles is related to clinical severity in a hip osteoarthritis population. AB - Osteoarthritis mainly affects weight-bearing joints such as the hip and knee and is the most common form of arthritis. Greater muscle atrophy with fatty infiltration of gluteal muscles and decreased hip abduction strength has previously been identified with increasing severity of radiological hip OA. However, it is well documented that radiographic findings of OA do not always correlate with clinical severity. The aim of this secondary analysis was to examine whether atrophy and strength of gluteus maximus (GMax), medius (GMed), minimus (GMin), and tensor fascia lata (TFL) is associated with the clinical severity of OA. Twenty participants with unilateral hip OA and 20 age- and sex matched asymptomatic controls were classified on the basis of clinical severity (mild, moderate-severe and asymptomatic groups) using the Oxford hip score. Muscle volumes of GMax, GMed, GMin, and TFL were determined using magnetic resonance imaging and expressed as asymmetry between limbs. A hand-held dynamometer was used to identify hip rotation and abduction strength. Regression analyzes were used to identify the association between muscle asymmetry and patient-reported severity of hip OA. Both symptomatic groups (mild and moderate severe) demonstrated significant asymmetry in GMax (P < 0.01) and GMin (P < 0.01). GMed asymmetry was associated with only the moderate-severe symptomatic group. Hip abduction strength was reduced in both symptomatic groups. Gluteal muscle atrophy was associated with the clinical severity of OA. Clinical severity could be a useful tool for clinicians interpreting likely gluteal muscle changes and planning rehabilitation strategies for hip OA patients. Clin. Anat. 31:507 513, 2018.

AB - OBJECTIVE: This study evaluated the effects of Alzheimer disease (AD) on the relationship between the brain noradrenergic system and hypothalamic pituitary adrenocortical axis (HPA). Specifically, relationships between cerebrospinal fluid (CSF) norepinephrine (NE) and CSF cortisol were examined in cognitively normal participants and participants with AD dementia and amnestic mild cognitive impairment (aMCI). We hypothesized that there would a positive association between these 2 measures in cognitively normal controls and that this association would be altered in AD. METHODS: Four hundred twenty-one CSF samples were assayed for NE and cortisol in controls (n = 305), participants with aMCI (n = 22), and AD dementia (n = 94). Linear regression was used to examine the association between CSF cortisol and NE, adjusting for age, sex, education, and body mass index. RESULTS: Contrary to our hypothesis, CSF cortisol and NE levels were not significantly associated in controls. However, higher cortisol levels were associated with higher NE levels in AD and aMCI participants. Regression coefficients +/- standard errors for the change in cortisol per 100-pg/mL increase in NE are as follows: controls 0.0 +/- 0.2, P = 1.0; MCI, 1.4 +/- 0.7, P = .14; and AD 1.1 +/- 0.4, P = .032. Analysis with MCI and AD participants combined strengthened statistical significance (1.2 +/- 0.3, P = .007). CONCLUSIONS: Enhanced responsiveness of the HPA axis to noradrenergic stimulatory regulation in AD and disruption of the blood brain barrier may contribute to these findings. Because brainstem noradrenergic stimulatory regulation of the HPA axis is substantially increased by both acute and chronic stress, these findings are also consistent with AD participants experiencing higher levels of acute and chronic stress. PMID- 29446124 TI - Using oral health assessment to predict aspiration pneumonia in older adults. AB - OBJECTIVE: To investigate the significance of comprehensive assessment of oral health using the revised oral assessment guide (ROAG) in older adults with pneumonia. BACKGROUND: Oral health plays a major role in the eating-swallowing process. The role of comprehensive assessment of oral health in older adults with aspiration pneumonia has not been evaluated in detail. The ROAG is a screening tool for comprehensive assessment and has been shown to have a high sensitivity and specificity for the assessment of oral health. MATERIALS AND METHODS: We retrospectively studied 238 adults with pneumonia, aged 65 years and above, in whom the ROAG score had been assessed between December 2014 and June 2016. Participants were divided into two groups based on aspiration risk, as defined by Marik et al; correlation between the ROAG score and the risk of aspiration was evaluated. RESULTS: Two hundred and fifteen adults (90.3%) were found to be at aspiration risk. According to the ROAG score, mild-to-moderate and severe oral problems were noted in 38 (16.0%) and 200 (84.0%) adults, respectively. Aspiration risk was noted in 68.4% and 94.5% of adults with mild-to-moderate and severe oral problems, respectively (P < .0001). The area under the receiver operating characteristics curve for ROAG to predict aspiration risk was 0.72 (95% confidence interval: 0.60-0.84). Furthermore, a high ROAG score was an independent predictor of aspiration risk in our study population. CONCLUSION: In clinical practice, oral health assessment using ROAG can help predict aspiration risk in older adults with pneumonia. PMID- 29446125 TI - Feasibility of high spatiotemporal resolution for an abbreviated 3D radial breast MRI protocol. AB - PURPOSE: To develop a volumetric imaging technique with 0.8-mm isotropic resolution and 10-s/volume rate to detect and analyze breast lesions in a bilateral, dynamic, contrast-enhanced MRI exam. METHODS: A local low-rank temporal reconstruction approach that also uses parallel imaging and spatial compressed sensing was designed to create rapid volumetric frame rates during a contrast-enhanced breast exam (vastly undersampled isotropic projection [VIPR] spatial compressed sensing with temporal local low-rank [STELLR]). The dynamic enhanced data are subtracted in k-space from static mask data to increase sparsity for the local low-rank approach to maximize temporal resolution. A T1 weighted 3D radial trajectory (VIPR iterative decomposition with echo asymmetry and least squares estimation [IDEAL]) was modified to meet the data acquisition requirements of the STELLR approach. Additionally, the unsubtracted enhanced data are reconstructed using compressed sensing and IDEAL to provide high-resolution fat/water separation. The feasibility of the approach and the dual reconstruction methodology is demonstrated using a 16-channel breast coil and a 3T MR scanner in 6 patients. RESULTS: The STELLR temporal performance of subtracted data matched the expected temporal perfusion enhancement pattern in small and large vascular structures. Differential enhancement within heterogeneous lesions is demonstrated with corroboration from a basic reconstruction using a strict 10-second temporal footprint. Rapid acquisition, reliable fat suppression, and high spatiotemporal resolution are presented, despite significant data undersampling. CONCLUSION: The STELLR reconstruction approach of 3D radial sampling with mask subtraction provides a high-performance imaging technique for characterizing enhancing structures within the breast. It is capable of maintaining temporal fidelity, while visualizing breast lesions with high detail over a large FOV to include both breasts. PMID- 29446126 TI - Layer-specific global longitudinal strain reveals impaired cardiac function in patients with reversible ischemia. AB - AIMS: Two-dimensional speckle tracking echocardiography (2DSTE) detects early signs of left ventricular dysfunction; however, it is unknown whether layer specific global longitudinal strain (GLS) has incremental value in diagnosis of patients with reversible ischemia assessed by single photon emission computed tomography (SPECT). METHODS AND RESULTS: Eighty patients with stable angina pectoris (SAP), normal left ventricular ejection fraction (LVEF), and no history of ischemic heart disease were retrospectively identified to have been examined by 2DSTE, SPECT, and coronary angiography (CAG). Patients with a normal SPECT constituted the control group, and patients with a positive SPECT were divided into patients with or without (true- or false- positive SPECT) significant stenosis assessed by CAG. GLS was measured for two myocardial layers (endocardial and epicardial) and as well as mid-myocardial GLS. Patients with reversible ischemia had significantly lower GLS compared to the control group (GLSEndocardial : -19.0 +/- 4.4% vs -21.4 +/- 3.7%, P = .011; GLSEpicardial : 14.3 +/- 2.9% vs -16.3 +/- 2.9%, P = .004); GLSMid-myocardial : -16.5 +/- 3.6% vs -18.6 +/- 3.2%, P = .006. This difference was even more evident in patients with a true-positive SPECT (GLSEndocardial : -18.0 +/- 4.4% vs -21.4 +/- 3.7%, P < .001; GLSEpicardial : -13.6 +/- 3.0% vs -16.3 +/- 2.9%, P < .001); GLSMid myocardial : -15.6 +/- 3.6% vs -18.6 +/- 3.2%, P < .001. Notably, no significant differences existed in patients with a false-positive SPECT. GLSEpicardial was the only independent predictor of coronary artery disease. IN CONCLUSION: In patients with SAP and preserved LVEF, layer-specific GLS at rest identifies patients with reversible ischemia. This seems to be evident only in patients with a true-positive SPECT, thus, 2DSTE at rest might improve the diagnostic accuracy of a positive SPECT.

AB - PURPOSE: To develop a whole-body MRI technique at 3T with improved lesion conspicuity for metastatic cancer detection using fast, high-resolution and high SNR T2 -weighted (T2 W) imaging with simultaneous fat and fluid suppression. THEORY AND METHODS: The proposed dual-echo T2 -weighted acquisition for enhanced conspicuity of tumors (DETECT) acquires 4 images, in-phase (IP) and out-of-phase (OP) at a short and a long TE using single-shot turbo spin echo. The IP/OP images at the short and long TEs are reconstructed using the standard Dixon and shared field-map Dixon reconstruction respectively, for robust fat-water separation. An adaptive complex subtraction between the 2 TE water-only images achieves fluid attenuation. DETECT imaging was optimized and evaluated in whole-body imaging of 5 healthy volunteers, and compared against diffusion-weighted imaging with background suppression (DWIBS) in 5 patients with known metastatic renal cell carcinoma. RESULTS: Robust fat-water separation and fluid attenuation were achieved using the shared-field-map Dixon reconstruction and adaptive complex subtraction, respectively. DETECT imaging technique generated co-registered T2 W images with and without fat suppression, heavily T2 W, and fat and fluid suppressed T2 W whole-body images in <7 min. Compared to DWIBS acquired in 17 min, the DETECT imaging achieved better detection and localization of lesions in patients with metastatic cancer. CONCLUSION: DETECT imaging technique generates T2 W images with high resolution, high SNR, minimal geometric distortions, and provides good lesion conspicuity with robust fat and fluid suppression in <7 min for whole-body imaging, demonstrating efficient and reliable metastatic cancer detection at 3T.

PMID- 29446144 TI - Animal models of multiple sclerosis: Focus on experimental autoimmune encephalomyelitis. AB - Multiple sclerosis (MS) is a chronic, progressive disorder of the central nervous system (CNS) that affects more than two million people worldwide. Several animal models resemble MS pathology; the most employed are experimental autoimmune encephalomyelitis (EAE) and toxin- and/or virus-induced demyelination. In this review we will summarize our knowledge on the utility of different animal models in MS research. Although animal models cannot replicate the complexity and heterogeneity of the MS pathology, they have proved to be useful for the development of several drugs approved for treatment of MS patients. This review focuses on EAE because it represents both clinical and pathological features of MS. During the past decades, EAE has been effective in illuminating various pathological processes that occur during MS, including inflammation, CNS penetration, demyelination, axonopathy, and neuron loss mediated by immune cells. PMID- 29446145 TI - Neuronal ceroid lipofuscinosis in Salukis is caused by a single base pair insertion in CLN8. AB - Neuronal ceroid lipofuscinoses (NCLs) are heterogenic inherited lysosomal storage diseases that have been described in a number of species including humans, sheep, cattle, cats and a number of different dog breeds, including Salukis. Here we present a novel genetic variant associated with the disease in this particular breed of dog. In a clinical case, a Saluki developed progressive neurological signs, including disorientation, anxiety, difficulties in eating, seizures and loss of vision, and for welfare reasons, was euthanized at 22 months of age. Microscopy showed aggregation of autofluorescent storage material in the neurons of several brain regions and also in the retina. The aggregates showed positive staining with Sudan black B and periodic acid Schiff, all features consistent with NCL. Whole genome sequencing of the case and both its parents, followed by variant calling in candidate genes, identified a new variant in the CLN8 gene: a single bp insertion (c.349dupT) in exon 2, introducing an immediate stop codon (p.Glu117*). The case was homozygous for the insertion, and both parents were heterozygous. A retrospective study of a Saluki from Australia diagnosed with NCL identified this case as being homozygous for the same mutation. This is the fourth variant identified in CLN8 that causes NCL in dogs. PMID- 29446146 TI - CRISPR/Cas9-mediated MSTN disruption and heritable mutagenesis in goats causes increased body mass. AB - Genetic engineering in livestock has been greatly enhanced through the use of artificial programmed nucleases such as the recently emerged clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated 9 (Cas9) system. We recently reported our successful application of the CRISPR/Cas9 system to engineer the goat genome through micro-injection of Cas9 mRNA and sgRNAs targeting MSTN and FGF5 in goat embryos. The phenotypes induced by edited loss-of function mutations of MSTN remain to be evaluated extensively. We demonstrate the utility of this approach by disrupting MSTN, resulting in enhanced body weight and larger muscle fiber size in Cas9-mediated gene-modified goats. The effects of genome modifications were further characterized by H&E staining, quantitative PCR, Western blotting and immunofluorescence staining. Morphological and genetic analyses indicated the occurrence of phenotypic and genotypic modifications. We further provide sufficient evidence, including breeding data, to demonstrate the transmission of the knockout alleles through the germline. By phenotypic and genotypic characterization, we demonstrated the merit of using the CRISPR/Cas9 approach for establishing genetically modified livestock with an enhanced production trait.

The effective chemotherapy for advanced EMPD has not been established. This study was designed to evaluate the efficacy of combination 5-fluorouracil (500 mg/body, 7 days/week) and cisplatin (5 mg/body 5 days/week) for invasive EMPD. Seventeen EMPD patients with multiple metastases who visited our dermatology clinic between October 2004 and May 2016 (mean age, 76.9 years; 10 men, seven women) were retrospectively analyzed. Eight EMPD patients underwent low-dose 5 fluorouracil/cisplatin therapy and nine patients chose best supportive care. The average number of treatment cycles was 12.3. All patients had a confirmed response, four (50%) showed a partial response, two (25%) stable disease and two progressive disease. The median times to progression-free and overall survival were 25.0 and 77.4 weeks, respectively. There was no severe (grade 3 and 4) adverse event. Although not significant, the survival of the patients treated with low-dose 5-fluorouracil/cisplatin therapy showed a trend toward improved survival as compared with best supportive care (P = 0.08, log-rank test). This regimen had low risk and relatively high disease control rate, suggesting that this regimen be recommended as one of the treatment options for advanced EMPD. PMID- 29446149 TI - Distinction of the GABA 2.29 ppm resonance using triple refocusing at 3 T in vivo. AB - PURPOSE: To develop 1 H MR spectroscopy that provides distinction of gamma aminobutyric acid (GABA) signal at 3 T in vivo. METHODS: Triple-refocusing was tailored at 3 T, with numerical simulations and phantom validation, for distinction of the GABA 2.29-ppm resonance from the neighboring glutamate resonance. The optimization was performed on the inter-RF pulse time delays and the duration and carrier frequency of a non-slice-selective RF pulse. The optimized triple refocusing was tested in multiple regions in 6 healthy subjects, including hippocampus. The in vivo spectra were analyzed with the LCModel using in-house basis spectra. After normalization of the metabolite signal estimates to water, the metabolite concentrations were quantified with reference to medial occipital creatine at 8 mM. RESULTS: A triple-refocusing scheme with optimized inter-RF pulse time delays (TE = 74 ms) was obtained for GABA detection. With optimized duration (14 ms) and carrier frequency (4.5 ppm) of the non-slice selective RF pulse, the triple refocusing gave rise to distinction between the GABA 2.29-ppm and glutamate 2.35-ppm signals. The GABA 2.29-ppm signal was clearly discernible in spectra in vivo (voxel size 4 to 12 mL; scan times 4.3 to 17 minutes). With a total of 24 spectra from 6 gray or white matter-dominant regions, the GABA concentration was measured to be 0.62 to 1.15 mM (Cramer-Rao lower bound of 8 to 14%), and the glutamate level 5.8 to 11.2 mM (Cramer-Rao lower bound of 3 to 6%). CONCLUSION: The optimized triple refocusing provided distinction between GABA and glutamate signals and permitted direct codetection of these metabolites in the human brain at 3 T in vivo. PMID- 29446150 TI - Antimicrobial peptide gene expression in periodontitis patients: A pilot study. AB - AIM: Antimicrobial peptides (AMPs) are one of the most active components of innate immunity and have characteristics that could place them at the heart of the pathogenesis of periodontal disease. This study investigated differences in the expression of AMP coding genes obtained using a simple harvesting technique, gingival smear, between two groups of patients: chronic periodontitis subjects versus healthy ones. MATERIALS AND METHODS: Twenty-three patients were enrolled in two groups: 12 were diagnosed with moderate or severe generalized chronic periodontitis, and 11 were diagnosed as clinically healthy. Gingival smears were retrieved and studied using reverse transcription-quantitative PCR (RT-qPCR) after mRNA purification. RESULTS: Fifteen gene expressions were obtained using real-time RT-qPCR. Three AMP genes, histatin 3 (HTN3), alpha-defensin 4 (DEFA4) and lysozyme C (LYZ), presented different expression levels in periodontitis patients compared with healthy subjects. The relative expression level of DEFA4 appeared to be a protective factor against periodontitis. CONCLUSION: Gingival smears studied by RT-qPCR may be used to assess the expression of AMPs coding genes. A lack of expression of DEFA4 could be a potential indicator of periodontitis status. PMID- 29446151 TI - Organisational framework and outputs of International medical evacuation in Guinea: A need for change. AB - The study aims to describe the organizational framework of International Medical Evacuation (IME), the profile of persons evacuated, and the associated cost of IME in Guinea. This was a descriptive study of IME policy in Guinea. We described the politico-structural organization of IME and the profile of patient accessing IME through the Ministry of Health (MOH: 2001-2015) and through the National Social Security Fund (NSSF: 2011-2015). From 1958 to 1992 since the health system was restricted, the country negotiated the free medical treatment with Socialist countries. Since 1992, a medical assistance line was included in the sector budgets, and IME was officially managed by the MOH and with a parallel system existing at the NSSF. With an average cost of US $34 251 per case, cardiovascular diseases (20%), Traumatology/Orthopedic diseases (20%), and Neurologic/neurosurgery diseases (12.5%) have motivated more than half of 2445 IME supported by the MOH between 2001 and 2015. With a diagnostic exploration (38.7%) as main motivation, the majority of the IMEs (80.0%) endorsed by the NSSF (2011-2015) concerned their employees/workers or those of the NSSF's supervisory ministry and their families. Despite a strict regulatory framework, the emergence and sustainability of parallel IME systems in other departments with different procedures than MOH's procedure represent a major weakness/deficiency. The new prospects for the free medical treatment of state employees could eventually lead to an effective correction of this structural failure if efficiently managed.

PMID- 29446153 TI - Eating fish and farm life reduce allergic rhinitis at the age of twelve. AB - BACKGROUND: The prevalence of allergic rhinitis has increased, but the cause of this rise is partly unknown. Our aim was to analyse the prevalence, risk factors, and protective factors for allergic rhinitis in 12-year-old Swedish children. METHODS: Data were collected from a prospective, longitudinal cohort study of children born in western Sweden in 2003. The parents answered questionnaires when the children were 6 months to 12 years. The response rate at 12 years was 76% (3637/4777) of the questionnaires distributed. RESULTS: At the age of 12, 22% of children had allergic rhinitis and 57% were boys. Mean age at onset was 7.8 years, and 55% reported their first symptoms after 8 years. The most common trigger factors were pollen (85%), furry animals (34%), and house dust mites (17%). A multivariate analysis showed that the adjusted odds ratios and 95% confidence intervals for the independent risk factors for allergic rhinitis at 12 were as follows: parental allergic rhinitis (2.32, 1.94-2.77), doctor-diagnosed food allergy in the first year (1.75, 1.21-2.52), eczema in the first year (1.61, 1.31-1.97), and male gender (1.25, 1.06-1.47). Eating fish once a month or more at age of 12 months reduced the risk of allergic rhinitis at 12 years of age (0.70, 0.50-0.98) as did living on a farm with farm animals at 4 years (0.51, 0.32-0.84). Continuous farm living from age 4 to 12 seemed to drive the association. CONCLUSIONS: Allergic rhinitis affected > 20% of 12-year-olds, but was lower in children who ate fish at 12 months or grew up on a farm with farm animals.

PMID- 29446155 TI - Not just trust: factors influencing learners' attempts to perform technical skills on real patients. AB - CONTEXT: As part of their training, physicians are required to learn how to perform technical skills on patients. The previous literature reveals that this learning is complex and that many opportunities to perform these skills are not converted into attempts to do so by learners. This study sought to explore and understand this phenomenon better. METHODS: A multi-phased qualitative study including ethnographic observations, interviews and focus groups was conducted to explore the factors that influence technical skill learning. In a tertiary paediatric emergency department, staff physician preceptors, residents, nurses and respiratory therapists were observed in the delivery and teaching of technical skills over a 3-month period. A constant comparison methodology was used to analyse the data and to develop a constructivist grounded theory. RESULTS: We conducted 419 hours of observation, 18 interviews and four focus groups. We observed 287 instances of technical skills, of which 27.5% were attempted by residents. Thematic analysis identified 14 factors, grouped into three categories, which influenced whether residents attempted technical skills on real patients. Learner factors included resident initiative, perceived need for skill acquisition and competing priorities. Teacher factors consisted of competing priorities, interest in teaching, perceived need for residents to acquire skills, attributions about learners, assessments of competency, and trust. Environmental factors were competition from other learners, judgement that the patient was appropriate, buy-in from team members, consent from patient or caregivers, and physical environment constraints. CONCLUSIONS: Our findings suggest that neither the presence of a learner in a clinical environment nor the trust of the supervisor is sufficient to ensure the learner will attempt a technical skill. We characterise this phenomenon as representing a pool of opportunities to conduct technical skills on live patients that shrinks to a much smaller pool of technical skill attempts. Learners, teachers and educators can use this knowledge to maximise the number of attempts learners make to perform technical skills on real patients.

AB - Greatly reduced scattering in the second near-infrared (NIR-II) region (1000-1700 nm) opens up many new exciting avenues of bioimaging research, yet NIR-II fluorescence imaging is mostly implemented by using nontargeted fluorophores or wide-field imaging setups, limiting the signal-to-background ratio and imaging penetration depth due to poor specific binding and out-of-focus signals. A newly developed high-performance NIR-II bioconjugate enables targeted imaging of a specific organ in the living body with high quality. Combined with a home-built NIR-II confocal set-up, the enhanced imaging technique allows 900 um-deep 3D organ imaging without tissue clearing techniques. Bioconjugation of two hormones to nonoverlapping NIR-II fluorophores facilitates two-color imaging of different receptors, demonstrating unprecedented multicolor live molecular imaging across the NIR-II window. This deep tissue imaging of specific receptors in live animals allows development of noninvasive molecular imaging of multifarious models of normal and neoplastic organs in vivo, beyond the traditional visible to NIR-I range. The developed NIR-II fluorescence microscopy will become a powerful imaging technique for deep tissue imaging without any physical sectioning or clearing treatment of the tissue. PMID- 29446158 TI - A neuroscience perspective of the gut theory of Parkinson's disease. AB - Parkinson's disease is caused by complex interactions between environmental factors and a genetic predisposition. Environmental factors include exposure to pesticides and toxins, heavy metals and accumulation of iron and/or manganese in the brain. However, accumulating evidence indicates that gut-brain health and function are impaired in Parkinson's disease, often a decade before motor symptoms are diagnosed. We present the gut-brain theory of Parkinson's disease and summarise the peripheral and central nervous system pathology, gastrointestinal symptoms experienced by many Parkinson's patients, the route by which gut-brain dysfunction may occur and changes in gut microbiota that are associated with disease expression. Finally, we consider future gut-based treatments to prevent or slow down the progression of Parkinson's disease and explore whether this knowledge may highlight biomarkers to be included in complex algorithms in the future to assess a person's risk of developing Parkinson's disease. PMID- 29446159 TI - Arginine vasopressin differentially modulates GABAergic synaptic transmission onto temperature-sensitive and temperature-insensitive neurons in the rat preoptic area. AB - The preoptic area (POA) of the hypothalamus, containing temperature-sensitive and temperature-insensitive neurons, plays a key role in specific thermoregulatory responses. Although arginine vasopressin (AVP) has been shown to induce hypothermia by increasing the firing activities of warm-sensitive neurons and decreasing those of cold-sensitive and temperature-insensitive neurons, the effects of AVP on POA GABAergic transmission remain unknown. Herein, inhibitory postsynaptic currents (IPSCs) of temperature-sensitive and temperature insensitive neurons in POA slices were recorded using whole-cell patch clamp. By monitoring changes in GABAergic transmission during AVP treatment, we showed that AVP decreased the amplitudes and frequencies of spontaneous IPSCs in mostly warm sensitive neurons and in some temperature-insensitive neurons but increased these parameters in other temperature-insensitive neurons. The IPSC amplitude was reduced for only cold-sensitive neurons. RT-PCR and Western blot analyses further confirmed the POA expression of V1a receptors and GABAA receptors, including the subunits alpha1, alpha2, alpha3, beta2, beta3 and gamma2. The effects of AVP on IPSCs in temperature-sensitive and temperature-insensitive neurons were dependent on G proteins and intracellular Ca2+ . AVP-mediated modulation was associated with changes in the kinetic parameters (decay time, 10-90% rise time, half width). Together, these results suggest that AVP, acting via V1a receptors but not V1b receptors, differentially modulates GABAergic synaptic transmission and fine-tunes the firing activities of temperature-sensitive and temperature insensitive neurons in the rat POA. PMID- 29446160 TI - Protection against summer solar lentigo over-pigmentation with a SPF30 daily cream. AB - BACKGROUND/PURPOSE: The aim of this study was to measure lentigines' pigmentation over a long period of time and evaluate if summer over-pigmentation can be avoided by the use a SPF30 day skin cream. METHODS: Seventeen healthy female volunteers aged 50 and over and presenting lentigines participated in the study from spring to summer. Throughout the study, all subjects applied a SPF30 daily skin cream to only one hand. Color measurements of the target lesions were performed with a chromameter and with a color-calibrated camera. Target lesions were also imaged with in vivo reflectance confocal microscopy (RCM). A specific procedure for re-registering the images was developed to ensure that the same papillae were measured over time. RESULTS: Both color measurement methods, chromametry and color-calibrated camera, showed that lentigines treated over time with the SPF30 day skin cream were significantly lighter than the non-treated lentigines. The RCM images showed a decrease in the papillary contrast for the treated lentigines. CONCLUSION: This study shows that this over-pigmentation can be avoided using a SPF30 day skin cream. Moreover, we have demonstrated that very fine re-registration of the RCM images is possible and ensures a more robust analysis.

AB - Bullous pemphigoid (BP) is a common autoimmune blistering disorder with unknown etiology. Recently, increasing numbers of BP cases which developed under the medication with dipeptidyl peptidase-4 inhibitors (DPP4i), widely used antihyperglycemic drugs, have been reported in published works. Here, we report a case of DPP4i (teneligliptin)-associated BP that developed in a 70-year-old Japanese man. Interestingly, the patient had acquired reactive perforating collagenosis (ARPC), which is also known to be associated with the onset of BP. In the present case, clinical, histopathological and immunological findings suggested that DPP4i rather than ARPC was associated with the onset of BP.

PMID- 29446165 TI - Synthetic Transient Crosslinks Program the Mechanics of Soft, Biopolymer-Based Materials. AB - Actin networks are adaptive materials enabling dynamic and static functions of living cells. A central element for tuning their underlying structural and mechanical properties is the ability to reversibly connect, i.e., transiently crosslink, filaments within the networks. Natural crosslinkers, however, vary across many parameters. Therefore, systematically studying the impact of their fundamental properties like size and binding strength is unfeasible since their structural parameters cannot be independently tuned. Herein, this problem is circumvented by employing a modular strategy to construct purely synthetic actin crosslinkers from DNA and peptides. These crosslinkers mimic both intuitive and noncanonical mechanical properties of their natural counterparts. By isolating binding affinity as the primary control parameter, effects on structural and dynamic behaviors of actin networks are characterized. A concentration-dependent triphasic behavior arises from both strong and weak crosslinkers due to emergent structural polymorphism. Beyond a certain threshold, strong binding leads to a nonmonotonic elastic pulse, which is a consequence of self-destruction of the mechanical structure of the underlying network. The modular design also facilitates an orthogonal regulatory mechanism based on enzymatic cleaving. This approach can be used to guide the rational design of further biomimetic components for programmable modulation of the properties of biomaterials and cells.

AB - AIM AND OBJECTIVES: To explore Iranian hospital nurses' lived experiences of intelligent resilience. BACKGROUND: Nurses do high levels of emotional work when fulfilling patients' and their family members' complex needs. Intelligent resilience can alleviate nurses' stress and enhance their endurance. DESIGN: This study was based on the Husserlian descriptive phenomenology. METHODS: A purposive sample of ten hospital nurses was drawn from hospitals affiliated with Hamadan University of Medical Sciences, Hamadan, Iran. In-depth semi-structured interviews were held to collect data. The seven-step data analysis approach proposed by Colaizzi was used for the data analysis. In this study, the adherence to consolidated criteria for reporting qualitative guidelines has been followed. RESULTS: The participating hospital nurses' lived experiences of intelligent resilience came into four main themes of patience and wisdom, reverence, situational self-control and appealing to religiosity. Each of the four main themes included two subthemes which were having peace and wise quietness, reverence for the patients, physicians and nurses, distancing themselves from stressful situations and displacing staff who cause stress, and the nurse's trust in God as well as the patient and his family's trust in God, respectively. CONCLUSION: Nurses with intelligent resilience are able to bring peace, reverence for others and situational self-control to stressors thereby providing higher quality of care to their patients. RELEVANCE TO CLINICAL PRACTICE: Nurses work in unstable and stressful conditions. The findings of this study provide better understanding about the concept of nurses' intelligent resilience and its indicators and attributes. PMID- 29446169 TI - Oxygen concentration modulates cellular senescence and autophagy in human trophoblast cells. AB - PROBLEM: We investigated the effect of oxygen concentrations on cellular senescence and autophagy and examined the role of autophagy in human trophoblast cells. METHOD OF STUDY: Human first-trimester trophoblast cells (Sw.71) were incubated under 21%, 5%, or 1% O2 concentrations for 24 hours. We examined the extent of senescence caused using senescence-associated beta-galactosidase (SA beta-Gal) and senescence-associated secretory phenotype (SASP) as markers. Moreover, we examined the role of autophagy in causing cellular senescence using an autophagy inhibitor (3-methyladenine, 3MA). RESULTS: Physiological normoxia (5% O2 ) decreased SA-beta-Gal-positive cells and SASP including interleukin-6 (IL-6) and IL-8 compared with cultured cells in 21% O2 . Pathophysiological hypoxia (1% O2 ) caused cytotoxicity, including extracellular release of ATP and lactate dehydrogenase, and decreased senescence phenotypes. 3MA-treated trophoblast cells significantly suppressed senescence markers (SA-beta-Gal positive cells and SASP secretion) in O2 -independent manner. CONCLUSION: We conclude that O2 concentration modulates cellular senescence phenotypes regulating autophagy in the human trophoblast cells. Moreover, inhibiting autophagy suppresses cellular senescence, suggesting that autophagy contributes to oxygen stress-induced cellular senescence. PMID- 29446170 TI - Magnetic resonance elastography of the lumbar back muscles: A preliminary study. AB - Back pain is associated with increased lumbar paraspinal muscle (LPM) stiffness identified by manual palpation and strain elastography. Recently, magnetic resonance elastography (MRE) has allowed the stiffness of muscle to be characterized noninvasively in vivo, providing quantitative 3D stiffness maps (elastograms). The aim of this study was to characterize the stiffness (shear modulus, SM) of the LPM (multifidus and erector spinae) using MRE. MRE of the lumbar region was performed on seven adults in supine position. MRE was acquired in three muscular states: relaxed with outstretched legs, stretched with passive pelvis flexion, and contracted with outstretched legs and tightened trunk muscles. The mean SM was measured within a region of interest manually defined in the multifidus, erector spinae, and the entire paraspinal compartment. The intermuscular difference and the effects of stretching and contraction were assessed by ANOVA and t-tests. At rest, the mean SM of the paraspinal compartment was 1.6 +/- 0.2 kPa. It increased significantly with stretching to 1.65 +/- 0.3 kPa, and with contraction to 2.0 +/- 0.7 kPa. Irrespective of muscular state, the erector spinae was significantly stiffer than the multifidus. The multifidus underwent proportionally higher stiffness changes from rest to contraction and stretching. MRE can be used to measure the stiffness of the LPM in different muscular states. We hypothesize that, irrespective of posture, the erector spinae behaves as semi-rigid beam, and ensures permanent stiffness of the spine. The multifidus behaves as an adaptable muscle that provides segmental flexibility to the spine and tunes the spine stiffness. Clin. Anat. 31:514-520, 2018. (c) 2018 Wiley Periodicals, Inc.

AB - OBJECTIVES: Cancer pain is common and difficult to treat, as conservative medical management fails in approximately 20% of patients for reasons such as intolerable side-effects or failure to control pain. Intrathecal drug delivery systems (IDDS), while underutilized, can be effective tools to treat intractable cancer pain. This study aims to determine the degree of pain relief, efficacy, and safety of patients who underwent IDDS implantation at a multidisciplinary pain clinic. MATERIALS AND METHODS: A retrospective review was conducted of patients with an intrathecal pain pump implanted for malignant pain. Charts were reviewed for demographics, cancer type, pain scores before and after implantation, and intrathecal drugs utilized. A Wilcoxon Signed-Rank test was conducted on the paired differences of pain scores before and after implant. A regression analysis was conducted using a linear model to assess effects of demographic variables on change in pain scores. RESULTS: 160 patients were included in analysis. The median pain score was 7.1 at time of implantation and 5.0 at one-month postimplantation. For patients with both baseline and one-month pain scores available, the median decrease in pain was 2.5 (p < 0.0001). Pain scores three month postimplantation did not significantly differ from one-month postimplantation. Median longevity was 65 days. Five patients had pumps explanted due to infection with a median time to pump extraction of 28 days. CONCLUSIONS: IDDS has the potential to improve cancer pain in a variety of patients and should be strongly considered as an option for those with cancer pain intractable to conservative medical management.

AB - AIMS AND OBJECTIVES: To measure the prevalence of symptomatic (S-IDH) and asymptomatic intradialytic hypotension (A-IDH) or postdialysis overhydration in a satellite haemodialysis clinic in Western Australia. BACKGROUND: Intradialytic hypotension is one of the most common side effects of haemodialysis caused by ultrafiltration provoking a temporary volume depletion. The prevalence of asymptomatic hypotension during dialysis has been rarely reported, but is considered to have the same negative consequences as symptomatic hypotension on various end organs like the brain and the gastrointestinal tract. DESIGN: Observational study on a retrospective 3-month period of nursing recorded fluid related adverse events. METHODS: Data collection on the occurrence of S-IDH and A IDH during a total of 2,357 haemodialysis treatments in 64 patients. Body weight of patients at the time of cessation of treatment was recorded, and patients, whose weight exceeded their ideal body weight by at least 0.5 kg, were classified as overhydrated. Data analysis was performed using spss version 24 software. RESULTS: Symptomatic intradialytic hypotension was the most common adverse event measured in this cohort, and occurred during 221 (9.4%) of all treatments, whereas asymptomatic intradialytic hypotension occurred in 88 (3.7%) of all treatments. The total occurrence of intradialytic hypotension was 13.1%, and symptomatic was observed in 30 patients, implying that nearly every second patient had at least one symptomatic episode within 3 months. Overhydration occurred in a total of 103 (4.4%) of all treatments, and involved 17 patients. CONCLUSIONS: Symptomatic and asymptomatic intradialytic hypotension were the most commonly observed adverse events in this cohort; overhydration occurrence was considerably less common. RELEVANCE TO CLINICAL PRACTICE: The high occurrence of hypotension-related events demonstrates that ultrafiltration treatment goals in satellite dialysis clinics are sometimes overestimated, resulting in regular significant symptomatic episodes for the patient. Raising the awareness of the prevalence of IDH amongst renal nurses could be an essential initial step before collectively preventative strategies in haemodialysis satellite units are implemented.

PMID- 29446174 TI - Comorbid depressive symptoms and self-esteem improve after either cognitive behavioural therapy or family-based treatment for adolescent bulimia nervosa. AB - This study examined the effect of family-based treatment for bulimia nervosa (FBT BN) and cognitive behavioral therapy for adolescents (CBT-A) on depressive symptoms and self-esteem in adolescents with BN. Data were collected from 110 adolescents, ages 12-18, who met Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition, text revision criteria for BN or partial BN. Participants were randomly assigned to FBT-BN or CBT-A and completed measures of depressive symptoms and self-esteem before and after treatment and at 6- and 12 month follow-up assessments. Depressive symptoms and self-esteem significantly improved in both treatments, and neither treatment appeared superior on these clinical outcomes. Parents often worry whether FBT-BN addresses comorbid depressive symptoms and low self-esteem. Our findings address this concern, as they demonstrate that FBT-BN does not differ from CBT-A in improving depressive symptoms and self-esteem, and both treatments result in symptom improvement. These findings can help clinicians guide families to choose a treatment that addresses BN and depressive symptoms and low self-esteem. PMID- 29446175 TI - Conceptualizing workplace cyberbullying: Toward a definition for research and practice in nursing. AB - AIMS: To explore nurses' understandings and perceptions of workplace cyberbullying, in order to develop a relevant and meaningful definition of the phenomenon for future research and practice. BACKGROUND: Although previous research places nurses at an elevated risk of exposure to traditional workplace bullying, there is a notable absence of research investigating workplace cyberbullying within this profession. Considering the detrimental outcomes experienced by the targets of workplace cyberbullying, this is an issue that warrants focus. METHODS: Utilizing relevant scenarios as prompts, semi-structured interviews were conducted with 16 nurses (practising and in training) to explore their understanding of the concept and dynamics of workplace cyberbullying. RESULTS: Three high-level themes were identified and discussed: (1) cyber specific features that make cyberbullying more damaging than traditional bullying; (2) the importance of context; and (3) the work environment factors that facilitate the occurrence of workplace cyberbullying. CONCLUSIONS: Our refined definition facilitates the investigation of a broader and more inclusive range of behaviours that targets may experience as workplace cyberbullying, and our findings in general highlight potential antecedents in common with traditional workplace bullying. IMPLICATIONS FOR NURSING MANAGEMENT: Given the work environment and the challenges faced by the nursing profession, a system wide approach to intervention and management is recommended, along with utilizing a nursing-specific definition. PMID- 29446176 TI - Meningococcal conjugate vaccine safety surveillance in the Vaccine Safety Datalink using a tree-temporal scan data mining method. AB - PURPOSE: The objective of our study was to conduct a data mining analysis to identify potential adverse events (AEs) following MENACWY-D using the tree temporal scan statistic in the Vaccine Safety Datalink population and demonstrate the feasibility of this method in a large distributed safety data setting. METHODS: Traditional pharmacovigilance techniques used in vaccine safety are generally geared to detecting AEs based on pre-defined sets of conditions or diagnoses. Using a newly developed tree-temporal scan statistic data mining method, we performed a pilot study to evaluate the safety profile of the meningococcal conjugate vaccine Menactra(r) (MenACWY-D), screening thousands of potential AE diagnoses and diagnosis groupings. The study cohort included enrolled participants in the Vaccine Safety Datalink aged 11 to 18 years who had received MenACWY-D vaccination(s) between 2005 and 2014. The tree-temporal scan statistic was employed to identify statistical associations (signals) of AEs following MENACWY-D at a 0.05 level of significance, adjusted for multiple testing. RESULTS: We detected signals for 2 groups of outcomes: diseases of the skin and subcutaneous tissue, fever, and urticaria. Both groups are known AEs following MENACWY-D vaccination. We also identified a statistical signal for pleurisy, but further examination suggested it was likely a false signal. No new MENACWY-D safety concerns were raised. CONCLUSIONS: As a pilot study, we demonstrated that the tree-temporal scan statistic data mining method can be successfully applied to screen broadly for a wide range of vaccine-AE associations within a large health care data network. PMID- 29446177 TI - How does retirement affect healthcare expenditures? Evidence from a change in the retirement age. AB - Using individual-level administrative panel data from Hungary, we estimate causal effects of retirement on outpatient and inpatient care expenditures and pharmaceutical expenditures. Our identification strategy is based on an increase in the official early retirement age of women, using that the majority of women retire upon reaching that age. According to our descriptive results, people who are working before the early retirement age have substantially lower healthcare expenditures than nonworkers, but the expenditure gap declines after retirement. Our causal estimates from a two-part (hurdle) model show that the shares of women with positive outpatient care, inpatient care, and pharmaceutical expenditures, respectively, decrease by 3.0, 1.4, and 1.3 percentage points in the short run due to retirement. These results are driven by the relatively healthy, by those who spent some time on sick leave and by the less educated. The effect of retirement on the size of positive healthcare expenditures is generally not significant. PMID- 29446178 TI - Health-promoting behaviours of Iranian nurses and its relationship with some occupational factors: A cross sectional study. AB - AIM: To assess the prevalence of health-promoting behaviours (HPBs) and their associations with some occupational factors among nurses. BACKGROUND: Health promoting behaviours are significant indicators of health status. Nurses' HPBs may have a direct impact on patients' care and safety. METHODS: A descriptive, questionnaire design was conducted among nursing staff (n = 136) in a district hospital in Iran during 2015. Data was collected using a two-part questionnaire, which included the Health Promoting Lifestyle Profile II. Data was analysed using the Pearson correlation coefficient, and independent t and ANOVA tests (alpha = .05). RESULTS: The stress-management and physical activity dimensions had the lowest mean score and health responsibility had the highest. The HPBs of nurses with rotating/irregular shifts, contract employment, and low income were significantly lower. CONCLUSIONS: Nurses' HPBs should be promoted in the stress management and physical activity dimensions. In this regard, contract nurses, shift nurses, and low-income nurses are the priorities. IMPLICATIONS FOR NURSING MANAGEMENT: Nurse managers should give more attention to promote nurses' HPBs especially in the areas of stress management and physical activity through implementation of healthy lifestyle programs. Nursing policy makers should give attention to permanent recruitment and improving salary as a strategy to improve nurses' HPBs. PMID- 29446179 TI - Genomic diversity of a nectar yeast clusters into metabolically, but not geographically, distinct lineages. AB - Both dispersal limitation and environmental sorting can affect genetic variation in populations, but their contribution remains unclear, particularly in microbes. We sought to determine the contribution of geographic distance (as a proxy for dispersal limitation) and phenotypic traits (as a proxy for environmental sorting), including morphology, metabolic ability and interspecific competitiveness, to the genotypic diversity in a nectar yeast species, Metschnikowia reukaufii. To measure genotypic diversity, we sequenced the genomes of 102 strains of M. reukaufii isolated from the floral nectar of hummingbird pollinated shrub, Mimulus aurantiacus, along a 200-km coastline in California. Intraspecific genetic variation showed no detectable relationship with geographic distance, but could be grouped into three distinct lineages that correlated with metabolic ability and interspecific competitiveness. Despite ample evidence for strong competitive interactions within and among nectar yeasts, a full spectrum of the genotypic and phenotypic diversity observed across the 200-km coastline was represented even at a scale as small as 200 m. Further, more competitive strains were not necessarily more abundant. These results suggest that dispersal limitation and environmental sorting might not fully explain intraspecific diversity in this microbe and highlight the need to also consider other ecological factors such as trade-offs, source-sink dynamics and niche modification. PMID- 29446180 TI - Pigs expressing the human inhibitory ligand PD-L1 (CD 274) provide a new source of xenogeneic cells and tissues with low immunogenic properties. AB - BACKGROUND: The programmed cell death-1 (PD-1, CD279)/PD-Ligand1 (PD-L1, CD274) receptor system is crucial for controlling the balance between immune activation and induction of tolerance via generation of inhibitory signals. Expression of PD L1 is associated with reduced immunogenicity and renders cells and tissues to an immune-privileged/tolerogenic state. METHODS: To apply this concept for clinical xenotransplantation, we generated human (h)PD-L1 transgenic pigs and characterized expression and biological function of the transgene at the cellular level. RESULTS: The hPD-L1 was detected in kidney, heart, and pancreas. In addition, peripheral blood mononuclear cells (PBMC), cultured fibroblasts, and endothelial cells were hPD-L1 positive (hPD-L1+ ). The hPD-L1 levels were increased by the treatment of transgenic cells with human cytokines (eg, TNF alpha), suggesting a regulatable mode of transgene expression. Compared to cells from wild-type pigs, hPD-L1+ PBMC had a significantly reduced capacity to stimulate proliferation of human CD4+ T cells. Moreover, fibroblasts from hPD-L1 transgenic pigs were partially protected from cell-mediated lysis by human cytotoxic effector cells. CONCLUSIONS: These data indicate a low immunogenic, immune-protected status of cells from hPD-L1 transgenic pigs. The integration of the hPD-L1 concept into existing multi-transgenic pigs is promising to achieve long-term survival of porcine xenografts in non-human primate recipients.

PMID- 29446182 TI - Catheter ablation of ventricular arrhythmias with QRS morphology resembling that of aortic sinus cusp arrhythmias: Significance of mapping the left pulmonary sinus cusp. AB - BACKGROUND: There is a close anatomical relationship between aortic sinus cusp (ASC) and the left pulmonary sinus cusp (LPSC). PURPOSE: The study was to investigate the significance of mapping and ablation of LPSC for ventricular arrhythmias (VAs) with QRS morphology resembling that of ASC arrhythmias. METHODS: In 33 consecutive patients undergoing successful catheter ablation of idiopathic VAs with ASC arrhythmia-like QRS morphology, LPSC was mapped carefully. RESULTS: Among the 33 patients studied, QRS morphology resembled that of arrhythmias of either right or left coronary cusp (LCC or RCC) origin in 17 and 16 patients, respectively. Out of 12 arrhythmias with the earliest potential in LCC during left-sided mapping, an earlier potential in LPSC than in LCC was recorded in 2 arrhythmias, the same earliest potential in LPSC as in LCC was recorded in 6 arrhythmias, and 5 (42%) were finally ablated successfully in LPSC using the reversed U curve. Out of 16 arrhythmias with the earliest potential in the RCC during left-sided mapping, an earlier potential in LPSC than in RCC was recorded in 4 arrhythmias, the same earliest potential in LPSC as in RCC was recorded in 3 arrhythmias, and 4 (25%) were finally ablated successfully in LPSC using the reversed U curve. CONCLUSIONS: For VAs with ASC arrhythmia-like QRS morphology, mapping in LPSC could have unique electrophysiologic characteristics, and some of them could be eliminated in LPSC using reversed U curve. PMID- 29446183 TI - Comparison of detergent-based decellularization protocols for the removal of antigenic cellular components in porcine aortic valve. AB - BACKGROUND: Various detergent-based protocols are used to remove cells and cellular debris in porcine aortic valve (PAV). However, the removal of antigenic cellular components has not been thoroughly elucidated to date. In this study, we used 4 detergent-based protocols to decellularize PAVs and aimed to evaluate their effects on removing antigenic cellular components. METHODS: Porcine aortic valves were decellularized using sodium dodecyl sulfate (SDS), SDS in combination with sodium deoxycholate (SDS/SD), Triton X-100, and Triton X-100 in combination with SD (Triton X-100/SD), respectively. Untreated PAVs were used as controls. Immunohistochemical and SDS-polyacrylamide gel electrophoresis (SDS-PAGE) analyses were performed to determine the removal of antigenic protein components. Histological, biochemical, and biomechanical analyses were performed to determine the preservation and mechanical properties of the extracellular matrix. PAV tissues were implanted subcutaneously in Sprague Dawley rats to evaluate the host immune response. Implanted PAVs were taken out at the indicated time points for histological and immunohistochemical examinations. RESULTS: All 4 protocols effectively removed the membrane antigenic proteins major histocompatibility complex I molecule and galactose-alpha-1,3 galactose. The SDS/SD protocol was the most effective method to remove the cytoplasmic cytoskeletal proteins, vimentin and alpha-SMA, and SDS alone partly removed vimentin protein. The SDS/SD protocol was the most effective method to remove nuclear DNA with residual DNA below 50 ng/mg, followed by the SDS protocol with residual DNA of 74.9 ng/mg. The SDS protocol was the most effective method to remove proteins ranged from 10 to 55 kDa, followed by the SDS/SD protocol. SDS and SDS/SD PAV implants attracted fewer neutrophils in vivo on postoperative day 3. The infiltration of macrophages and T lymphocytes was significantly lower in SDS and SDS/SD implants on days 14 and day 28. All of the decellularized protocols that were examined greatly reduced the contents of collagen, elastin, and glycosaminoglycan compared to controls. Biomechanical analysis revealed significant differences in ultimate tensile strength and Young's modulus between control PAVs and decellularized PAVs generated using SDS, SDS/SD, Triton X-100, or Triton X-100/SD. CONCLUSIONS: These results indicated that SDS-based protocols more effectively removed antigenic cellular components compared to Triton X-100-based protocols. These results are clinically significant because complete removal of antigenic determinants is critical to decrease adverse immune-mediated and inflammatory responses to a PAV when used in xenogeneic application. PMID- 29446184 TI - Microwave-Assisted, Asymmetric Synthesis of 3-Amino-2,3-Dihydrobenzofuran Flavonoid Derivatives from Chalcones. AB - A route to access 3-amino-2,3-dihydrobenzofurans that utilizes microwave-assisted organic synthesis to rapidly generate analogues has been developed. The route begins with an acid-catalyzed, microwave-assisted aldol condensation to generate chalcone intermediates, followed by a Corey-Bakshi-Shibata reduction and subsequent Sharpless asymmetric epoxidation to access stereoisomeric epoxyalcohols. The final step is a one-pot, microwave-assisted, regioselective, acid-catalyzed epoxide opening with various amines followed by an intramolecular nucleophilic aromatic substitution reaction to generate the 3-amino-2,3 dihydrobenzofurans. This route provides ready access to stereochemically and structurally diverse analogues of these flavonoid scaffolds. Additionally, a pilot library was synthesized, and the biological activity diversity of the chalcones and dihydrobenzofurans was explored in human carcinoma cell lines. PMID- 29446185 TI - Chart validation of inpatient ICD-9-CM administrative diagnosis codes for acute myocardial infarction (AMI) among intravenous immune globulin (IGIV) users in the Sentinel Distributed Database. AB - BACKGROUND: The Sentinel Distributed Database (SDD) is a large database of patient-level administrative health care records, primarily derived from insurance claims and electronic health records, and is sponsored by the US Food and Drug Administration for medical product safety evaluations. Acute myocardial infarction (AMI) is a common study endpoint for drug safety studies that rely on health records from the SDD and other administrative databases. PURPOSE: In this chart validation study, we report on the positive predictive value (PPV) of inpatient International Classification of Diseases, Ninth Revision, Clinical Modification AMI administrative diagnosis codes (410.x1 and 410.x0) in the SDD. METHODS: As part of an assessment of thromboembolic adverse event risk following treatment with intravenous immune globulin, charts were obtained for 103 potential post-intravenous immune globulin AMI cases. Charts were abstracted by trained nurses and physician-adjudicated based on prespecified diagnostic criteria. RESULTS: Acute myocardial infarction status could be determined for 89 potential cases. The PPVs for the inpatient AMI diagnoses recorded in the SDD were 75% overall (95% CI, 65-84%), 93% (95% CI, 78-99%) for principal-position diagnoses, 88% (95% CI, 72-97%) for secondary diagnoses, and 38% (95% CI, 20-59%) for position-unspecified diagnoses (eg, diagnoses originating from separate physician claims associated with an inpatient stay). Of the confirmed AMI cases, demand ischemia was the suspected etiology more often for those coded in secondary or unspecified positions (72% and 40%, respectively) than for principal position AMI diagnoses (21%). CONCLUSIONS: The PPVs for principal and secondary AMI diagnoses were high and similar to estimates from prior chart validation studies. Position-unspecified diagnosis codes were less likely to represent true AMI cases. PMID- 29446186 TI - Longterm persistence and nonrecurrence of depression treatment in Germany: a four year retrospective follow-up using linked claims data. AB - OBJECTIVES: To measure persistence and nonrecurrence of depression treatment and investigate potential risk factors. METHODS: We retrospectively observed a closed cohort of insurees with new-onset depression treatment in 2007 and without most psychiatric comorbidity for 16 quarters (plus one to ascertain discontinuation). We linked inpatient/outpatient/drug-data per person and quarter. Person-quarters containing specified depression services were classified as depression-treatment person-quarters (DTPQ). We defined longterm-DTPQ-persistence as 16 + 1 continuous DTPQ and longterm-DTPQ-nonrecurrence as 12 continuous quarters without DTPQ and used multivariate logistic regression to explore associations with these outcomes. RESULTS: Within first 16 quarters, 28,348 patients' first period (total time) persisted for a mean/median 5.4/3 (8.7/8) quarters. Fourteen percent had longterm-DTPQ-persistence, associated (p < .05) with baseline hospital (odds ratio, OR = 1.80), psychotherapy/specialist-interview and antidepressants (OR = 1.81), age (years, OR = 1.03), unemployment (OR = 1.21), retirement (OR = 1.31), and insured as a dependent (OR = 1.32). Thirty-four percent had longterm-DTPQ nonrecurrence, associated with psychotherapy/specialist-interview (OR = 1.40), antidepressants (OR = 0.54), female sex (OR = 0.84), age (years, OR = 0.99), retirement (OR = 1.18), and insured as a dependent (OR = 0.88). Women differed for episodic and not chronic treatment. CONCLUSION: Treatment measures compared to survey's symptoms measures. We suggest further research on "treatment-free time." Antidepressants(-) and psychotherapy/specialist-interview(+) were significantly associated with longterm-DTPQ-nonrecurrence. This was presumably moderated by possible short-time/low-dosage antidepressants use(-) and selective therapy assignment(+). Sample selectivity limited data misclassification. PMID- 29446187 TI - 4-Fluorophenyl 3-nitro-2-pyridinesulfenate as a practical protecting agent for amino acids. AB - We report a new protecting agent (1, Npys-OPh(pF)) for 3-nitro-2-pyridine (Npy) sulfenylation of amino, hydroxy, and thiol functional groups. Several Npys phenoxides were synthesized from Npys chloride (Npys-Cl) and phenols in the presence of base in 1-step reaction, and their ability for Npy-sulfenylation was evaluated. As a result, 1 was selected as a new Npy-sulfenylation agent with advantages including improved physicochemical stability, more controllable reactivity, and easier handling than the conventional protecting agent Npys-Cl.

AB - The first catalytic inverse hydroboration of imines with N-heterocyclic carbene (NHC) boranes has been realized by means of cooperative organocatalysis and photocatalysis. This catalytic combination provides a promising platform for promoting NHC-boryl radical chemistry under sustainable and radical-initiator free conditions. The highly important functional-group compatibility and possible application in late-stage hydroborations represent an important step forward to an enhanced alpha-amino organoboron library. PMID- 29446189 TI - Parents' experiences of neonatal transfer. A meta-study of qualitative research 2000-2017. AB - Transfers of critically ill neonates are frequent phenomena. Even though parents' participation is regarded as crucial in neonatal care, a transfer often means that parents and neonates are separated. A systematic review of the parents' experiences of neonatal transfer is lacking. This paper describes a meta-study addressing qualitative research about parents' experiences of neonatal transfer. Through deconstruction and reflections of theories, methods, and empirical data, the aim was to achieve a deeper understanding of theoretical, empirical, contextual, historical, and methodological issues of qualitative studies concerning parents' experiences of neonatal transfer over the course of this meta study (2000-2017). Meta-theory and meta-method analyses showed that caring, transition, and family-centered care were main theoretical frames applied and that interviewing with a small number of participants was the preferred data collection method. The meta-data-analysis showed that transfer was a scary, unfamiliar, and threatening experience for the parents; they were losing familiar context, were separated from their neonate, and could feel their parenthood disrupted. We identified 'wavering and wandering' as a metaphoric representation of the parents' experiences. The findings add knowledge about meta-study as an approach for comprehensive qualitative research and point at the value of meta theory and meta-method analyses. PMID- 29446190 TI - Entropy-Driven Diastereoselectivity Improvement in the Paterno-Buchi Reaction of 1-Naphthyl Aryl Ethenes with a Chiral Cyanobenzoate through Remote Alkylation. AB - The precise stereocontrol of photocycloaddition reactions is still a significant challenge owing to their mechanistic complexity and the involvement of highly reactive and short-lived intermediates. Attempts have hitherto been made through structural modifications, mostly by introducing steric conflicts, to increase the difference between the enthalpic barriers. Herein, we show that entropy plays a crucial role in influencing the diastereoselectivity of a Paterno-Buchi reaction. Remote meta alkylation of the donor caused nominal changes in its photophysical properties as well as those of the exciplexes derived thereof. Nevertheless, the diastereomeric excess of the oxetane product was greatly improved by about 40 %. This enhancement, which is not accompanied by any significant changes in the photophysical properties, is difficult to rationalize by conventional enthalpic control concepts based on repulsive steric and/or attractive intermolecular interactions as well as electronic perturbations. Differential activation parameters and compensatory enthalpy-entropy relationships revealed that the diastereoselectivity enhancement is not simply enthalpic but also entropic in origin. PMID- 29446191 TI - Speech understanding in noise in elderly adults: the effect of inhibitory control and syntactic complexity. AB - BACKGROUND: Previous research has suggested that speech perception in elderly adults is influenced not only by age-related hearing loss or presbycusis but also by declines in cognitive abilities, by background noise and by the syntactic complexity of the message. AIMS: To gain further insight into the influence of these cognitive as well as acoustic and linguistic factors on speech perception in elderly adults by investigating inhibitory control as a listener characteristic and background noise type and syntactic complexity as input characteristics. METHODS & PROCEDURES: Phoneme identification was measured in different noise conditions and in different linguistic contexts (single words, sentences with varying syntactic complexity). Additionally, inhibitory control was measured using a visual stimulus-response matching task. Fifty-one adults participated in this study, including elderly adults with age-related hearing loss (n = 9) and with normal hearing (n = 17), and a control group of normal hearing younger adults (n = 25). OUTCOMES & RESULTS: The analysis revealed that elderly adults with normal hearing and with hearing loss were less likely to identify successfully phonemes in single words than younger normal hearing controls. In the context of sentences, only elderly adults with hearing loss had a lower odds of correct phoneme perception than the control group. Additionally, in elderly adults with hearing loss, phoneme-in-sentence perception was linked to age-related declines in inhibitory control. In all participants, phoneme identification in sentences was influenced by both noise type and syntactic complexity. CONCLUSIONS & IMPLICATIONS: Inhibitory control and syntactic complexity might play a significant role in speech perception, especially in elderly listeners. These factors might also influence the results of clinical assessments of speech perception. Testing procedures thus need to be selected and their results interpreted carefully with these influences in mind. PMID- 29446192 TI - Increasing the autotrophic growth of Chlorella USTB-01 via the control of bacterial contamination by Bdellovibrio USTB-06. AB - AIMS: (i) To obtain and identify the predatory bacteria for the control of contaminated bacteria and to promote the autotrophic growth of Chlorella USTB-01. (ii) To identify and measure the different cell numbers in microalgal culture using flow cytometer. METHODS AND RESULTS: A predatory bacterial strain was isolated using Escherichia coli BL21 as a sole prey host, which was identified as Bdellovibrio USTB-06 by the analysis of 16S rDNA sequence. A flow cytometer was successfully used to identify and measure the cell numbers of Chlorella USTB-01, the contaminated bacteria and Bdellovibrio USTB-06 simultaneously in the autotrophic culture of Chlorella USTB-01 according to the identification of the different cell sizes. With the addition of Bdellovibrio USTB-06 at initial 104 plaque-forming units per ml, the contaminated bacteria severely decreased by about five counts (in log10 CFU per ml) and the growth of Chlorella USTB-01 was greatly increased by 37.0% compared with those of control respectively. CONCLUSIONS: Bdellovibrio USTB-06 could effectively promote the growth of Chlorella USTB-01 via the killing of the contaminated bacteria. SIGNIFICANCE AND IMPACT OF THE STUDY: Our study reveals a good biotechnology method to increase the growth of Chlorella USTB-01 which is very important in the industry of microalgal culture. PMID- 29446193 TI - Impact of nonintrusive clinical decision support systems on laboratory test utilization in a large academic centre. AB - BACKGROUND: The near-universal prevalence of electronic health records (EHRs) has made the utilization of clinical decision support systems (CDSS) an integral strategy for improving the value of laboratory ordering. Few studies have examined the effectiveness of nonintrusive CDSS on inpatient laboratory utilization in large academic centres. METHODS: Red blood cell folate, hepatitis C virus viral loads and genotypes, and type and screens were selected for study. We incorporated the appropriate indications for these labs into text that accompanied the laboratory orders in our hospital's EHR. Providers could proceed with the order without additional clicks. An interrupted time-series analysis was performed, and the primary outcome was the rate of tests ordered on all inpatient medicine floors. RESULTS: The rate of folate tests ordered per monthly admissions showed no significant level change at the time of the intervention with only a slight decrease in rate of 0.0109 (P = .07). There was a 43% decrease in the rate of hepatitis C virus tests per monthly admissions immediately after the intervention with a decrease of 0.0135 tests per monthly admissions (P = .02). The rate of type and screens orders per patient days each month had a significant downward trend by 0.114 before the intervention (P = .04) but no significant level change at the time of the intervention or significant change in rate after the intervention. DISCUSSION: Our study suggests that nonintrusive CDSS should be evaluated for individual laboratory tests to ensure only effective alerts continue to be used so as to avoid increasing EHR fatigue.

PMID- 29446195 TI - Attachment and therapeutic alliance in psychological therapy for people with recent onset psychosis who use cannabis. AB - We examine associations between client attachment style and therapeutic alliance in a 3-arm randomized controlled trial of brief motivational interviewing and cognitive-behavioural therapy compared with longer term motivational interviewing and cognitive-behavioural therapy or standard care alone. Client self-report measures of attachment style were completed at baseline, and both clients and therapists in the treatment arms of the trial completed alliance measures 1 month into therapy. We found that insecure-anxious attachment was positively associated with therapist-rated alliance, whereas clients with insecure-avoidant attachment were more likely to report poorer bond with therapist. There was no evidence that client attachment significantly predicted clinical or substance misuse outcomes either directly or indirectly via alliance. Nor evidence that the length of therapy offered interacted with attachment to predict alliance. PMID- 29446196 TI - Laboratory maintenance does not alter ecological and physiological patterns among species: a Drosophila case study. AB - Large comparative studies in animal ecology, physiology and evolution often use animals reared in the laboratory for many generations; however, the relevance of these studies hinges on the assumption that laboratory populations are still representative for their wild living conspecifics. In this study, we investigate whether laboratory-maintained and freshly collected animal populations are fundamentally different and whether data from laboratory-maintained animals are valid to use in large comparative investigations of ecological and physiological patterns. Here, we obtained nine species of Drosophila with paired populations of laboratory-maintained and freshly collected flies. These species, representing a range of ecotypes, were assayed for four stress-tolerance, two body-size traits and six life-history traits. For all of these traits, we observed small differences in species-specific comparisons between field and laboratory populations; however, these differences were unsystematic and laboratory maintenance did not eclipse fundamental species characteristics. To investigate whether laboratory maintenance influence the general patterns in comparative studies, we correlated stress tolerance and life-history traits with environmental traits for the laboratory-maintained and freshly collected populations. Based on this analysis, we found that the comparative physiological and ecological trait correlations are similar irrespective of provenience. This finding is important for comparative biology in general because it validates comparative meta-analyses based on laboratory-maintained populations.

PMID- 29446199 TI - Light-Dependent Cytoplasmic Recruitment Enhances the Dynamic Range of a Nuclear Import Photoswitch. AB - Cellular signal transduction is often regulated at multiple steps to achieve more complex logic or precise control of a pathway. For instance, some signaling mechanisms couple allosteric activation with localization to achieve high signal to noise. Here, we create a system for light-activated nuclear import that incorporates two levels of control. It consists of a nuclear import photoswitch, light-activated nuclear shuttle (LANS), and a protein engineered to preferentially interact with LANS in the dark, Zdk2. First, Zdk2 is tethered to a location in the cytoplasm that sequesters LANS in the dark. Second, LANS incorporates a nuclear localization signal (NLS) that is sterically blocked from binding to the nuclear import machinery in the dark. If activated with light, LANS both dissociates from its tethered location and exposes its NLS, which leads to nuclear accumulation. We demonstrate that this coupled system improves the dynamic range of LANS in mammalian cells, yeast, and Caenorhabditis elegans and provides tighter control of transcription factors that have been fused to LANS.

AB - Multinuclear heterometallic nanoclusters with controllable stoichiometry and structure are anticipated to possess promising catalytic, magnetic, and optical properties. Heterometallic nanoclusters with precise stoichiometry of Bi3 Cu4 and Bi7 Cu12 can be stabilized in the scaffold of two-dimensional metal-organic networks on a Cu(111) surface through on-surface metallosupramolecular self assembly processes. The atomic structures of the nanoclusters were resolved using scanning tunneling microscopy and density functional theory calculations. The nanoclusters feature highly symmetric planar hexagonal shapes and core-shell charge modulation. The clusters are arranged as triangular lattices with a periodicity that can be tuned by choosing molecules of different size. This work shows that on-surface metallosupramolecular self-assembly creates unique possibilities for the design and synthesis of multinuclear heterometallic nanoclusters. PMID- 29446201 TI - Transposable elements shape the human proteome landscape via formation of cis acting upstream open reading frames. AB - Transposons are major drivers of mammalian genome evolution. To obtain new insights into the contribution of transposons to the regulation of protein translation, we here examined how transposons affected the genesis and function of upstream open reading frames (uORFs), which serve as cis-acting elements to regulate translation from annotated ORFs (anORFs) located downstream of the uORFs in eukaryotic mRNAs. Among 39,786 human uORFs, 3,992 had ATG trinucleotides of a transposon origin, termed "transposon-derived upstream ATGs" or TuATGs. Luciferase reporter assays suggested that many TuATGs modulate translation from anORFs. Comparisons with transposon consensus sequences revealed that most TuATGs were generated by nucleotide substitutions in non-ATG trinucleotides of integrated transposons. Among these non-ATG trinucleotides, GTG and ACG were converted into TuATGs more frequently, indicating a CpG methylation-mediated process of TuATG formation. Interestingly, it is likely that this process accelerated human-specific upstream ATG formation within transposon sequences in 5' untranslated regions after divergence between human and nonhuman primates. Methylation-mediated TuATG formation seems to be ongoing in the modern human population and could alter the expression of disease-related proteins. This study shows that transposons have potentially been shaping the human proteome landscape via cis-acting uORF creation. PMID- 29446202 TI - Conditional deletion of Cadherin 13 perturbs Golgi cells and disrupts social and cognitive behaviors. AB - Inhibitory interneurons mediate the gating of synaptic transmission and modulate the activities of neural circuits. Disruption of the function of inhibitory networks in the forebrain is linked to impairment of social and cognitive behaviors, but the involvement of inhibitory interneurons in the cerebellum has not been assessed. We found that Cadherin 13 (Cdh13), a gene implicated in autism spectrum disorder and attention-deficit hyperactivity disorder, is specifically expressed in Golgi cells within the cerebellar cortex. To assess the function of Cdh13 and utilize the manipulation of Cdh13 expression in Golgi cells as an entry point to examine cerebellar-mediated function, we generated mice carrying Cdh13 floxed alleles and conditionally deleted Cdh13 with GlyT2::Cre mice. Loss of Cdh13 results in a decrease in the expression/localization of GAD67 and reduces spontaneous inhibitory postsynaptic current (IPSC) in cerebellar Golgi cells without disrupting spontaneous excitatory postsynaptic current (EPSC). At the behavioral level, loss of Cdh13 in the cerebellum, piriform cortex and endopiriform claustrum have no impact on gross motor coordination or general locomotor behaviors, but leads to deficits in cognitive and social abilities. Mice lacking Cdh13 exhibit reduced cognitive flexibility and loss of preference for contact region concomitant with increased reciprocal social interactions. Together, our findings show that Cdh13 is critical for inhibitory function of Golgi cells, and that GlyT2::Cre-mediated deletion of Cdh13 in non-executive centers of the brain, such as the cerebellum, may contribute to cognitive and social behavioral deficits linked to neurological disorders.

PMID- 29446204 TI - An up to 17-year follow-up retrospective analysis of a minimally invasive, flapless approach: 18 945 implants in 7783 patients. AB - BACKGROUND: This study investigates gender, age, jaw, implant position, loading protocol (immediate vs delayed), smoking, and type of surgery (punch vs flap) as influential factors of implant survival in a large patient collective. PURPOSE: To evaluate the survival rates of implants in patients using a mucoperiosteal punch for flapless implantation in the majority of cases in order to evaluate its medical efficacy and safety. MATERIALS AND METHODS: Between 1994 and 2015 all patients with complete data treated at the Wienerberg Dental Clinic, Vienna, Austria, were included and statistically analyzed in Cox proportional hazard (PH) models. As patients with multiple implants were included, a clustering term was added to the Cox PH model to respect pooled failures in patients. RESULTS: Of the initial 24 282 ANKYLOS/Dentsply implants placed in 8137 patients a total of 7783 patients with 18 945 implants were finally included. The mean follow-up was 2.8 +/- 3.2 up to 17.9 years. Cumulative survival rates (CSRs) after 1, 3, 5, and 10 years were 98.5%, 97.7%, 96.7%, and 93.0%, respectively. Of these, 17 517 (92.5%) implants were placed minimally invasive via a flapless approach by use of the ATP Punch with comparable survival rates as observed for flap surgery. The Cox PH models proved smoking (hazard ratio [HR] = 2.2) and implant position as significant factors of implant survival. In the maxilla, canines and third molars were identified as low risk sites in comparison to the most frequently implanted first premolar site. In the mandible, the central incisor and second premolar were identified as high-risk sites, the canine as low risk site in comparison to the most frequently placed first molar site. CONCLUSION: The analyzed data concludes the safety and medical efficacy of the ATP-Punch. The CSRs using this flapless technique are comparable to the classic surgical flap approach. PMID- 29446205 TI - Surgeon-led prostate cancer lymph node staging: pathological outcomes stratified by robot-assisted dissection templates and patient selection. AB - OBJECTIVES: To evaluate the perioperative, pathological, and oncological outcomes from surgeon-led pathological staging of pelvic lymph node (LN) metastases at the time of robot-assisted radical prostatectomy (RARP). PATIENTS AND METHODS: Over the 6-year period of 2006-2012, three distinct pelvic LN dissection (PLND) strategies were used in chronological order at a single cancer referral hospital. Strategies were characterised by both an omission of PLND (pNx) vs inclusion decision threshold, and standard vs extended templates for patients selected for PLND. The three cohorts included: (i) omission vs standard template (04/2006 10/2007), for dominant Gleason score 4-5 or a prostate-specific antigen (PSA) level of >10 ng/mL; (ii) omission/standard vs extended template (11/2007 12/2010), for dominant Gleason score 4-5, PSA level of >10 ng/mL, any single core >7 mm, or >3 ipsilateral positive cores; and (iii) extended template with minimal exceptions (01/2011-08/2012). Standard outcomes data compared included: Clavien Dindo complication rates, LN metrics (yield, percentage positive), and biochemical recurrence (BCR). A novel metric comprised 'pNx regret': the rate of pNx patients upgraded/upstaged. Exploratory analyses included selection criteria for reduced PLND templates, i.e. low-yield subsets. RESULTS: Standard PLND yielded 8-10 LNs and a positive-LN yield of 2.2-6.2%. The addition of an extended PLND (E-PLND) significantly increased the yield to 14-20 LNs and the positive-LN yield to 17.4-18.4% (both P < 0.001). E-PLND had the highest impact on the percentage of positive LNs (%pN1) for high-risk disease (9.3 vs 32.8%, P = 0.002), modest for intermediate risk (4.2 vs 10.9%, P = 0.003), and minimal impact on low risk disease (4.1 vs 0%, P = 0.401). The combined strategies of setting a very low threshold for E-PLND and sending separate LN packets increased the LN yields (18 vs 24, P < 0.001), but did not significantly change the observed %pN1 rates by clinical risk group (P = 0.975). Efforts to reduce the need for E-PLND included omission by clinical criteria, but resulting in 'pNx regret' in 16-19%. A third of patients with unilateral disease and positive LNs were found to have contralateral disease. A subset of men with minimal biopsy volume Gleason score 4 + 3 had pN1 rates after E-PLND of three of 14 (21%) compared to minimal biopsy volume Gleason score 3 + 4 pN1 rates after E-PLND of 0 of 31. E-PLND takes about twice as long to perform but with no statistically significant difference in complications (5.0 vs 6.0%, P = 0.511). The 5-year BCR rates were higher for E-PLND, given the selection criteria, but not different for overall survival. CONCLUSIONS: The net benefit of E-PLND remains uncertain, and therapeutic impact will probably require a randomised trial, given the strong selection criteria. E-PLND contributes to oncological staging in a significant number of high- and intermediate-risk patients, and should be bilateral. Immediate concerns include longer operative times, but no higher complication rates. PMID- 29446206 TI - Regression equations to estimate the 2-min walk distance in an adult Asian population aged 40-75 years. AB - BACKGROUND AND OBJECTIVE: There is increased use of the 2-min walk test (2MWT) to assess functional exercise capacity. However, the distance achieved during this test may be difficult to interpret in the absence of reference values from a local population. Regression equations to estimate the 2-min walk distance (2MWD) only exist for American and Brazilian populations. The objective of this study was to develop regression equations to estimate the 2MWD in Malaysian adults who were free from major health problems. METHODS: Eighty-seven adults (43 males; mean +/- SD age: 57.1 +/- 9.6 years) performed two 2MWT using a standardized protocol. Heart rate (HR) was recorded every 30 s during the test. Stepwise multiple regression analysis was performed using age, gender, height, weight and change in HR (DeltaHR) as independent variables, and better of the two 2MWD as the dependent variable. A second regression equation, without DeltaHR, was planned if DeltaHR was retained as one of the predictors of the 2MWD in the first equation. RESULTS: The better of the two 2MWD was 200 +/- 34 m. Males walked 33 +/- 6 m further than females (P < 0.001). The two regression equations were 196 - 1.1 * age, years + 1.0 * DeltaHR, bpm + 31.2 * gender (R2 = 0.73) and 279 - 1.7 * age, years + 35.9 * gender (R2 = 0.47) with females = 0 and males = 1. CONCLUSION: The equations derived in this study may facilitate the interpretation of the 2MWD in clinical populations in Malaysia, as well as in countries with similar cultural backgrounds to Malaysia. PMID- 29446207 TI - VEGF mitigates histone-induced pyroptosis in the remote liver injury associated with renal allograft ischemia-reperfusion injury in rats. AB - Clinical evidence has indicated a possible link between renal injury and remote liver injury. We investigated whether extracellular histone mediates remote hepatic damage after renal graft ischemia-reperfusion injury, while vascular endothelial growth factor (VEGF) is protective against remote hepatic injury. In vitro, hepatocyte HepG2 cultures were treated with histone. In vivo, the Brown Norway renal graft was stored in 4 degrees C preservation solution for 24 hours and then transplanted into a Lewis rat recipient; blood samples and livers from recipients were harvested 24 hours after surgery. Prolonged cold ischemia in renal grafts enhanced liver injury 24 hours after engraftment. Caspase-1, ASC, NLRP3, and AIM2 expressions in hepatocyte, CD68+ -infiltrating macrophages, tissue, and serum interleukin-1beta and -18 were greatly elevated, indicating that pyroptosis occurred in the liver and resulted in acute liver functional impairment. Blocking the caspase-1 pathway decreased the number of necrotic hepatocytes. VEGF treatment suppressed the hepatocyte pyroptosis and liver function was partially restored. Our data suggested that renal allograft ischemia reperfusion injury is likely associated with acute liver damage due to hepatocyte pyroptosis induced by histone and such injury may be protected by VEGF administration. VEGF, therefore, may serve as a new strategy against other remote organ injuries related to renal transplantation. PMID- 29446209 TI - Effect of the iChoose Kidney decision aid in improving knowledge about treatment options among transplant candidates: A randomized controlled trial. AB - We previously developed a mobile- and web-based decision aid (iChoose Kidney) that displays individualized risk estimates of survival and mortality, for the treatment modalities of dialysis versus kidney transplantation. We examined the effect of iChoose Kidney on change in transplant knowledge and access to transplant in a randomized controlled trial among patients presenting for evaluation in three transplant centers. A total of 470 patients were randomized to standard transplantation education (control) or standard education plus iChoose Kidney (intervention). Change in transplant knowledge (primary outcome) among intervention versus control patients was assessed using nine items in pre- and postevaluation surveys. Access to transplant (secondary outcome) was defined as a composite of waitlisting, living donor inquiries, or transplantation. Among 443 patients (n = 226 intervention; n = 216 control), the mean knowledge scores were 5.1 +/- 2.1 pre- and 5.8 +/- 1.9 postevaluation. Change in knowledge was greater among intervention (1.1 +/- 2.0) versus control (0.4 +/- 1.8) patients (P < .0001). Access to transplantation was similar among intervention (n = 168; 74.3%) versus control patients (n = 153; 70.5%; P = .37). The iChoose Kidney decision aid improved patient knowledge at evaluation, but did not impact transplant access. Future studies should examine whether combining iChoose Kidney with other interventions can increase transplantation. (Clinicaltrials.gov NCT02235571). PMID- 29446208 TI - Study rationale, design, and pretransplantation alloantibody status: A first report of Clinical Trials in Organ Transplantation in Children-04 (CTOTC-04) in pediatric heart transplantation. AB - Anti-HLA donor-specific antibodies are associated with worse outcomes after organ transplantation. Among sensitized pediatric heart candidates, requirement for negative donor-specific cytotoxicity crossmatch increases wait times and mortality. However, transplantation with positive crossmatch may increase posttransplantation morbidity and mortality. We address this clinical challenge in a prospective, multicenter, observational cohort study of children listed for heart transplantation (Clinical Trials in Organ Transplantation in Children-04 [CTOTC-04]). Outcomes were compared among sensitized recipients who underwent transplantation with positive crossmatch, nonsensitized recipients, and sensitized recipients without positive crossmatch. Positive crossmatch recipients received antibody removal and augmented immunosuppression, while other recipients received standard immunosuppression with corticosteroid avoidance. This first CTOTC-04 report summarizes study rationale and design and relates pretransplantation sensitization status using solid-phase technology. Risk factors for sensitization were explored. Of 317 screened patients, 290 were enrolled and 240 underwent transplantation. Core laboratory evaluation demonstrated that more than half of patients were anti-HLA sensitized. Greater than 80% of sensitized patients had class I (with or without class II) HLA antibodies, and one-third of sensitized patients had at least 1 HLA antibody with median fluorescence intensity of >=8000. Logistic regression models demonstrated male sex, weight, congenital heart disease history, prior allograft, and ventricular assist device are independent risk factors for sensitization. PMID- 29446210 TI - Lead exposure reduces sperm quality and DNA integrity in mice. AB - Toxicity of lead on male reproductive functions has raised wide public concern as environmental lead contamination remains common worldwide. Conflicting and controversial data are available regarding effects of lead on male fertility. More importantly, our knowledge on effects of lead on sperm DNA integrity is significantly limited. Thus, further studies should focus on this issue. In the current study, adult male mice were exposed to a series of lead acetate concentrations in drinking water for six weeks. Following administration, lead levels in blood, testicles, and epididymis were measured, and potential changes in morphology of testis and epididymis due to lead exposure were identified. We also analyzed sperm parameters, including sperm density, viability, motility, and morphology, to evaluate quality of sperm collected from epididymis. Especially, hypothetical influence of lead on sperm DNA integrity was also evaluated by terminal deoxynucleotidyltransferase-mediated dUTP-biotin nick end labeling, alkaline comet assay, and sperm chromatin structure assay. Lead exposure possibly exerted no effect on growth of mice because these animals acquired similar body weight gain during the experimental period. However, high lead concentrations (0.5% and 1%) in drinking water affected sperm motility and increased percentage of spermatozoa with abnormal morphology. In groups treated with 0.25%, 0.5%, and 1% lead acetate, percentages of sperm cells showing DNA breaks and chromatin structure damage significantly increased. Altogether, lead exposure not only exhibits adverse effects on sperm physiological parameters, but also impairs DNA structure and integrity. These effects may lead to significant decline in male fertility. PMID- 29446198 TI - Mutational spectrum in a worldwide study of 29,700 families with BRCA1 or BRCA2 mutations. AB - The prevalence and spectrum of germline mutations in BRCA1 and BRCA2 have been reported in single populations, with the majority of reports focused on White in Europe and North America. The Consortium of Investigators of Modifiers of BRCA1/2 (CIMBA) has assembled data on 18,435 families with BRCA1 mutations and 11,351 families with BRCA2 mutations ascertained from 69 centers in 49 countries on six continents. This study comprehensively describes the characteristics of the 1,650 unique BRCA1 and 1,731 unique BRCA2 deleterious (disease-associated) mutations identified in the CIMBA database. We observed substantial variation in mutation type and frequency by geographical region and race/ethnicity. In addition to known founder mutations, mutations of relatively high frequency were identified in specific racial/ethnic or geographic groups that may reflect founder mutations and which could be used in targeted (panel) first pass genotyping for specific populations. Knowledge of the population-specific mutational spectrum in BRCA1 and BRCA2 could inform efficient strategies for genetic testing and may justify a more broad-based oncogenetic testing in some populations. PMID- 29446211 TI - The benefit sharing vision of H3Africa. AB - One of the central ethical tenets of research in developing countries is the sponsor's obligation to benefit host participants and communities. Two known models of benefits provision dominate the ethical discourse of research in developing countries. The first model, known as the "reasonable availability," endorses the obligation to provide interventions proven to be effective at the end of a study. This contrasts with the second model, known as "fair benefits," which endorses other forms of benefits that host communities may deem as fair beyond those derived directly from the study's findings. This paper explores a third benefit model consistent with the writings of the Human Hereditary and Health in Africa (H3Africa) research initiative. The H3Africa-a North-South collaborative initiative predicated by U.S. National Institutes of Health, the Wellcome Trust and the African Society of Human Genetics upholds a benefit model that endorses capacity building as the primary obligation of its research agenda. This is evident by the endorsement of mechanisms to strengthen capacity building in its research projects. While capacity building remains a plausible means of improving the expertise, quality and independence of research in Africa, sustainable measures are needed to realizing the full potential for African-led research on the continent. PMID- 29446212 TI - Free dialysis in Nepal: Logistical challenges explored. AB - Nepal's Ministry of Health began offering free lifetime hemodialysis (HD) in 2016. There has been a large growth in renal replacement therapy (RRT) services offered in Nepal since 2010, when the last known data on the subject was published. In 2016, 42 HD centers existed (223% increase since 2010) serving 1975 end stage renal disease patients (303% increase since 2010); 36 nephrologists were registered (200% increase since 2010), 12 were trained in transplantation, and 790 transplants had been performed to date. We estimate the incidence of end stage renal disease to be 2900 patients (100 per million population). With an annual cost of approximately US$2300 per dialysis patient, offering free dialysis could potentially cost the government US$6.7 million per year, suggesting that 2.1% of the annual health budget would be allocated to 0.01% of the population. The geographic zone surrounding the capital city, Kathmandu, contains 50% of HD centers, but only 14.5% of Nepal's population. Forty-eight percent of the population lives within zones without HD service, therefore infrastructure challenges exist in providing equitable access to RRT. The aim of this article is to summarize the current statistics of RRT in Nepal. PMID- 29446213 TI - Osteopontin is essential for IL-1beta production and apoptosis in peri implantitis. AB - BACKGROUND AND PURPOSE: Peri-implantitis is caused by a cascade of host and microbial factors leading to an oral inflammatory disease. The inflammation proliferates into supporting tissues surrounding implants and may finally lead to a complete loss of osseointegration. Being a phosphorylated glycoprotein secreted by immunocompetent cells, osteopontin (OPN) is involved in the differentiation of odontoblast-like cells during pulpal healing following tooth transplantation and the secretion of type I collagen in reparative dentin. But the production and function of OPN in peri-implantitis has not been thoroughly evaluated. MATERIALS AND METHODS: Peri-implant crevicular fluid (PICF) was collected from 28 healthy implants patients and 28 peri-implantitis patients to determine the expression of OPN in response to the inflammation of peri-implantitis by Western-blot, Enzyme linked immunosorbent assay (ELISA), and immunofluorescence staining. THP-1 macrophages infected by Porphyromonas gingivalis were chosen to reveal the production and function of OPN in peri-implantitis by immunofluorescence staining, quantitative polymerase chain reaction (RT-PCR), and Western-blot. RESULTS: Results showed that OPN increased in most PICF of peri-implantitis patients and in THP-1 macrophages stimulated with P. gingivalis. The expression of OPN in response to P. gingivalis decreased at mRNA and protein levels when exposed to either the lectin-type oxidized LDL receptor 1 (LOX-1) neutralizing antibody or inhibitor pretreatment in THP-1 macrophages. P. gingivalis induces OPN through the Erk1/2 MAPK dependent pathway. OPN neutralization decreased interleukin 1 beta (IL-1beta) expression on P. gingivalis infection, and the lower IL-1beta mRNA and protein levels were rescued by human osteopontin recombinant protein (rhOPN) in THP-1 macrophages. RhOPN suppressed P. gingivalis induced apoptosis of the mitochondrial pathway in THP-1 macrophage. CONCLUSIONS: Overall, the results of this study provide insight into the essential roles of OPN for IL-1beta production and apoptosis in peri-implantitis, as supported by the evidence from the study of patient's PICF and cell culture experiments. PMID- 29446214 TI - New developments in India concerning the policy of passive euthanasia. AB - Euthanasia and assisted dying are illegal in India according to Sections 306 and 309 of the Indian Penal Code (IPC), and Article 21 of the Constitution of India. There have been a number of cases where the Indian High Courts and Indian Supreme Court issued differing verdicts concerning the right to life and the right to die. Nevertheless, on 7 March 2011, a paradigm shift happened as a result of the Indian Supreme Court's judgment on involuntary passive euthanasia in the case of Aruna Shanbaug. In its judgment, the Supreme Court requested the government to prepare a law on euthanasia. Accordingly, the 241st Report of the Law Commission of India proposed a bill to permit passive euthanasia. In May 2016 the Ministry of Health and Family Welfare (MOHFW) issued the draft bill for public comment in order to create an informed decision. The Indian people are divided on the issue of euthanasia. The majority of the scientific community welcome it, while some religious groups oppose it. Hindus, in general, express both supporting and opposing views on euthanasia, whereas, Christians and Muslims have hardened their opposition against it. The Supreme Court judgment and the Report of the Law Commission pave the way for the development of new policies pertaining to passive euthanasia by the central government of India. Once such legislation is passed, passive euthanasia may, and probably will, have an enormous impact on the cultural, political, public and medical spheres of India in the near future. PMID- 29446215 TI - Elevated success of multispecies bacterial invasions impacts community composition during ecological succession. AB - Successful microbial invasions are determined by a species' ability to occupy a niche in the new habitat whilst resisting competitive exclusion by the resident community. Despite the recognised importance of biotic factors in determining the invasiveness of microbial communities, the success and impact of multiple concurrent invaders on the resident community has not been examined. Simultaneous invasions might have synergistic effects, for example if resident species need to exhibit divergent phenotypes to compete with the invasive populations. We used three phylogenetically diverse bacterial species to invade two compositionally distinct communities in a controlled, naturalised in vitro system. By initiating the invader introductions at different stages of succession, we could disentangle the relative importance of resident community structure, invader diversity and time pre-invasion. Our results indicate that multiple invaders increase overall invasion success, but do not alter the successional trajectory of the whole community. PMID- 29446216 TI - Bipolar II should only exist if we can actually study treatments of it. Otherwise, what purpose does it serve? PMID- 29446217 TI - Clinical staging model in offspring of parents with bipolar disorder: a systematic review. AB - OBJECTIVE: We sought to systematically review the literature on the psychiatric risk of offspring of parents with bipolar disorder (OPBD) using a developmental psychopathology framework. The review also sought to establish the utility of clinical stage modelling as a framework for identifying precursor disorders to later onset of bipolar disorder (BD) in OPBD. METHODS: A systematic search was performed using EMBASE, PsychINFO and Medline. Reference lists of included studies and previous reviews were also searched. Studies were included if they reported diagnostic outcomes for child, adolescent and young adult offspring of parents diagnosed with BD. RESULTS: Twenty-six studies were identified representing 21 individual cohorts. The review identified that OBPD present as a high-risk group for a range of mood and non-mood disorders in childhood, adolescence and young adulthood. The trajectory of risk was from non-mood disorders in childhood via non-bipolar mood disorders in early adolescence towards mania/hypomania in late adolescence and early adulthood. From a clinical staging perspective, childhood anxiety disorders were associated with later onset of BD. Recurrent substance use disorder was identified as a risk in OPBD during late adolescence and early adulthood. Quality ratings indicated that studies were methodologically robust. CONCLUSIONS: Our review provides evidence for a developmental psychopathology trajectory of precursor risks to BD in OPBD. There is support for clinical stage modelling as a conceptual framework for understanding developmental risk in OPBD and as a tool for developing early and individualized intervention strategies. PMID- 29446218 TI - Influence of grandparents on the dietary intake of their 2-12-year-old grandchildren: A systematic review. AB - AIM: Grandparents are assuming increased child-caregiving responsibilities, which potentially influences the dietary intake of grandchildren. The aim of this systematic review is to determine the influence of grandparental care on the dietary intake, food-related behaviours, food choices and weight status of their preschool and school-aged grandchildren. METHODS: Six electronic health databases were searched in January 2017. Inclusion criteria were publication in English language, peer-reviewed journal between 2000 and 2017; children aged 2-12 years; study outcomes included child dietary intake/weight status, grandparent nutrition knowledge/beliefs or grandparent/parent feeding practices. Included studies were appraised for quality and bias. The review was registered with PROSPERO, number CRD42016047518. RESULTS: Sixteen studies were identified in the review, published between 2007 and 2016, with 15 assessed as moderate or high quality. Nine studies reported grandparental child feeding attitudes and behaviours that are considered to negatively influence child dietary intake, while three studies identified positive influences. Seven studies identified that differences in child feeding attitudes and behaviours between parents and grandparents created conflict and tensions between caregivers, often resulting in poor feeding practices. Statistically significant positive associations (odds ratio 1.47-1.72) between grandparent cohabitation and increased rates of child overweight and obesity were found in four studies. CONCLUSIONS: Grandparents in caregiving roles may negatively influence the dietary intake and weight status of their grandchildren. More rigorous, targeted studies are required to further define the mechanisms by which grandparents' knowledge, attitudes and feeding behaviours may influence child dietary intake. This review suggests that grandparents may be an important audience to target in future child nutrition interventions. PMID- 29446219 TI - Hypertension in a resource-limited setting: Is it associated with end organ damage in older adults in rural Tanzania? AB - Few data from sub-Saharan Africa exist on the effects of hypertension on the organs of the human body. We aimed to establish the prevalence of hypertensive end organ damage (EOD) in an elderly cohort of Tanzanians. The population aged 70 years and over of 2 villages in northern Tanzania (n = 246), had blood pressure (BP) data available from 2010 and 2013, and underwent in-depth follow-up for markers of hypertensive EOD in 2016. Assessment included ankle-brachial pressure index, lying-standing BP, electrocardiogram, and mid-stream urine dip. Sustained hypertension (those with hypertension at all 3 assessments) was found in 129 (52.4% subjects). Of the entire cohort, 13.9% had left ventricular hypertrophy and 26.4% had peripheral arterial disease, both of which were associated with sustained hypertension, although orthostatic hypotension, stroke, proteinuria, and arterial stiffening were not. Further investigation, particularly in younger age groups, is merited if hypertension-associated morbidity is to be controlled. PMID- 29446220 TI - Density-dependent survival varies with species life-history strategy in a tropical forest. AB - Species coexistence in diverse communities likely results from multiple interacting factors. Mechanisms such as conspecific negative density dependence (CNDD) and varying life-history strategies related to resource partitioning are known to influence plant fitness, and thereby community composition and diversity. However, we have little understanding of how these mechanisms interact and how they vary across life stages. Here, we document the interaction between CNDD and life-history strategy, based on growth-mortality trade-offs, from seedling to adult tree for 47 species in a tropical forest. Species' life-history strategies remained consistent across stages: fast-growing species had higher mortality than slow-growing species at all stages. In contrast, mean CNDD was strongest at early life stages (i.e. seedling, sapling). Fast-growing species tended to suffer greater CNDD than slow-growing species at several, but not all life stages. Overall, our results demonstrate that coexistence mechanisms interact across multiple life stages to shape diverse tree communities. PMID- 29446221 TI - Stereodivergent Evolution of Artificial Enzymes for the Michael Reaction. AB - Enzymes are valuable biocatalysts for asymmetric synthesis due to their exacting stereocontrol. Changing the selectivity of an existing catalyst for new applications is, however, challenging. Here we show that, in contrast, the stereoselectivity of an artificial enzyme created by design and directed evolution is readily tunable. We engineered a promiscuous artificial retro aldolase into four stereocomplementary catalysts for the Michael addition of a tertiary carbanion to an unsaturated ketone. Notably, this selectivity is also preserved with alternative Michael nucleophiles. Complete stereodiversification of other designer enzymes should similarly be possible by extension of these approaches. PMID- 29446222 TI - Engineering controls in veterinary oncology: A survey of 148 ACVIM board certified oncologists and environmental surveillance in 20 specialty hospitals. AB - Engineering controls (EC, facility and equipment barriers between hazards and people) are used to avoid exposure to chemotherapy drugs. In this study, American College of Veterinary Internal Medicine board-certified veterinary oncologists were surveyed about their use of containment primary EC (C-PEC) and supplemental EC (closed system transfer devices, CSTD). The survey was completed by 148 (38%) of practicing diplomates. All used EC. Both C-PEC and CSTD were used at 92% of hospitals; however, US Pharmacopoeial Convention Chapter <800> (USP <800>) standards were met at only 19% of hospitals and oncologists did not know the type of C-PEC at 18% of hospitals. Next, surface contamination and EC use were assessed with environmental surveillance for carboplatin, cyclophosphamide, doxorubicin, and vincristine in 20 veterinary specialty hospitals using a commercially available kit. No contamination with carboplatin, doxorubicin, or vincristine was detected, however, there was contamination with cyclophosphamide at 4 hospitals. Based on this study, most veterinary oncologists use C-PEC and CSTD, but few meet USP <800> standards. Current measures appear effective for preventing contamination with IV drugs, but additional measures are needed for oral drugs. PMID- 29446223 TI - Evolution and development of scyphozoan jellyfish. AB - Scyphozoan jellyfish, or scyphomedusae, are conspicuous members of many ocean ecosystems, and have large impacts on human health and industry. Most scyphomedusae are the final stage in a complex life cycle that also includes two intermediate stages: the larval planula and benthic polyp. In species with all three life-cycle stages, the metamorphosis of a polyp into a juvenile scyphomedusa (ephyra) is termed strobilation, and polyps can produce one ephyra (termed monodisc strobilation) or many ephyrae (termed polydisc strobilation). In contrast to species with planula, polyp and medusa stages, a handful of scyphozoan species possess modified life cycles with reduced or absent stages. The evolutionary patterns associated with strobilation and life-cycle type have not been thoroughly investigated, and many studies of ephyra development and strobilation induction are not yet synthesized. Herein, I place the development of scyphomedusae in an evolutionary context. I first review the current evolutionary hypotheses for Scyphozoa. Next, I review what is known about scyphomedusa development across a broad diversity of species, including the first signs of strobilation, the formation of strobila segments, and the morphogenesis of ephyrae. I then review cases where the canonical scyphozoan life cycle has been modified, and take advantage of phylogenetic hypotheses to place these observations in an evolutionary context. I show that the evolution of monodisc strobilation occurred at least twice, and that the loss of intermediate life cycle stages occurred several times independently; by contrast, the reduction of the medusa stage appears to have occurred within a single clade. I then briefly review the major natural cues of strobilation induction. Finally, I summarize what is currently known about the molecular mechanisms of strobilation induction and ephyra development. I conclude with suggestions for future directions in the field. PMID- 29446224 TI - Comparative effects of small intestinal glucose on blood pressure, heart rate, and noradrenaline responses in obese and healthy subjects. AB - Meal consumption leads to an increase in sympathetic output to compensate for hemodynamic changes and maintain blood pressure (BP). Obesity is associated with a blunting of the sympathetic response to meal ingestion, but interpretation of studies investigating these responses is compromised by their failure to account for the rate of gastric emptying, which is an important determinant of postprandial cardiovascular and sympathetic responses and, in both health and obesity, exhibits a wide interindividual variation. We sought to determine the effects of intraduodenal glucose infusion, bypassing gastric emptying, on BP, heart rate (HR), and noradrenaline responses in obese and healthy control subjects. 12 obese subjects (age 36.6 +/- 3.9 years, body mass index (BMI) 36.1 +/- 1.3 kg/m2 ) and 23 controls (age 27.8 +/- 2.4 years, BMI 22.4 +/- 0.5 kg/m2 ) received intraduodenal infusions of glucose at 1 or 3 kcal/min, or saline, for 60 min (t = 0-60 min), followed by intraduodenal saline (t = 60-120 min). BP and HR were measured with an automatic cuff, and blood samples collected for measurement of plasma noradrenaline. Intraduodenal glucose at 1 kcal/min was associated with a fall in diastolic BP in the control subjects only (P < 0.01), with no change in systolic BP, HR or noradrenaline in either group. In both groups, intraduodenal glucose at 3 kcal/min was associated with a fall in diastolic (P < 0.01), but not systolic, BP, and rises in HR (P < 0.001) and plasma noradrenaline (P < 0.01), with no difference in responses between the groups. We conclude that cardiovascular and sympathetic responses to intraduodenal glucose infusion are comparable between obese and control subjects, and dependent on the rate of glucose delivery.

AB - We aimed to evaluate the influence of urological complications occurring within the first year after kidney transplantation on long-term patient and graft outcomes, and sought to examine the impact of the management approach of ureteral strictures on long-term graft function. We collected data on urological complications occurring within the first year posttransplant. Graft survivals, patient survival, and rejection rates were compared between recipients with and without urological complications. Male gender of the recipient, delayed graft function, and donor age were found to be significant risk factors for urological complications after kidney transplantation (P < .05). Death censored graft survival analysis showed that only ureteral strictures had a negative impact on long-term graft survival (P = .0009) compared to other complications. Death censored graft survival was significantly shorter in kidney recipients managed initially with minimally invasive approach when compared to the recipients with no stricture (P = .001). However, graft survival was not statistically different in patients managed initially with open surgery (P = .47). Ureteral strictures following kidney transplantation appear to be strongly negatively correlated with long-term graft survival. Our analysis suggests that kidney recipients with ureteral stricture should be managed initially with open surgery, with better long-term graft survival. PMID- 29446226 TI - Towards donor lung recovery-gene expression changes during ex vivo lung perfusion of human lungs. AB - We and others have demonstrated that acellular normothermic ex vivo lung perfusion of high-risk donor lungs can result in posttransplant outcomes equivalent to that of contemporaneous lung transplantation using standard donor lungs. However, the mechanism of this effect remains unclear. Given the restoration of cellular metabolic activity during normothermic perfusion, one possibility is that of lung healing via natural innate recovery mechanisms. We explored this by examining the gene expression changes occurring in human lungs during ex vivo lung perfusion. Human lungs clinically rejected for transplantation were perfused for 12 hours of EVLP with biopsies taken at the start, at 1 hour, at 3 hours, and then every 3 hours thereafter to 12 hours. Temporal changes were identified in 2585 genes using the Short Time-series Expression Miner and used for pathway analysis. Despite increases in endothelial markers of inflammation, circulating leukocyte cell-specific gene expression fell over 12 hours of ex vivo lung perfusion (EVLP), suggesting an interrupted inflammation response secondary to washout of circulating leukocytes. Analysis of these gene changes suggests lung recovery follows specific stages: cellular death, cellular preservation, cellular reorganization, and cellular invasion. EVLP may improve posttransplant lung function by washout of leukocytes and facilitating innate mechanisms of repair.

AB - A rapid, low-cost, and simple method is proposed based on a miniaturized solid phase extraction named microextraction in packed syringe coupled with gas chromatography and mass spectrometry for the preconcentration and determination of some organophosphorous pesticides including diazinon, ethion, and malathion. For the first time, natural nanoperlite is used as a safe sorbent. Based on this technique, the analytes are adsorbed on the solid phase and then eluted by a desorbing solvent. The influence of some important parameters such as the solution pH, type, and volume of the organic desorption solvent on the microextraction efficiency of the selected pesticide technique is investigated. The proposed method showed a good linearity in the range of 1.0-35.0 MUg/L for ethion and 0.4-30.0 MUg/L for both diazinon and malathion. The limits of detection in the range of 0.1-0.38 MUg/L were obtained using the selected ion monitoring mode of the mass spectrometer. The reproducibility of the method was found to be in the range of 2.8-8.9% for the studied pesticides. To evaluate the matrix effect, the developed method is also applied to the preconcentration and determination of the selected pesticides in real water samples. PMID- 29446229 TI - Biogeographical distribution of bacterial communities in Changbai Mountain, Northeast China. AB - The broad-leaved and Korean pine mixed forest in Changbai Mountain, China is an important component of boreal forest; the area is sensitive to global climate change. To understand spatial distribution patterns of soil bacterial community along elevation, we analyzed the soil bacterial community diversity and composition along an elevational gradient of 699-1177 m in a primitive Korean pine forest in Changbai Mountain using the high-throughput sequencing. In total, 149,519 optimized sequences were obtained. Bacterial Shannon index increased along elevation from 699 m to 937 m and started to decrease at the elevation of 1,044 m, showing a humpback curve along elevation. Evenness (ACE index) and richness (Chao index) of the soil bacterial community both decreased with elevation (the highest values of 770 and 762 at 699 m and the lowest values of 548 and 539 at 1,177 m, respectively), all the indices are significantly different between elevations. Bacterial composition at phylum and genus levels had some differences between elevations, but the dominant bacterial populations were generally consistent. Beta-diversity analysis showed a distance-decay pattern of bacterial community similarity at different samples. Soil physical and chemical properties explained 70.78% of the variation in bacterial community structure (soil pH explained 19.95%), and elevational distance only explained 8.42%. In conclusion, the contemporary environmental disturbances are the critical factors in maintaining the bacterial spatial distribution compared with historical contingencies.

PMID- 29446231 TI - Estimating the burden of influenza-associated hospitalizations and deaths in Chile during 2012-2014. AB - BACKGROUND: Influenza is a vaccine preventable disease that causes important morbidity and mortality worldwide. Estimating the burden of influenza disease is difficult. However, there are some methods based in surveillance data and laboratory testing that can be used for this purpose. OBJECTIVES: Estimating the burden of serious illness from influenza by means of hospitalization and death records during the period between 2012 and 2014, and using information from Severe Acute Respiratory Illness (SARI) surveillance. METHODS: To estimate the Chilean rate of influenza-associated hospitalizations and deaths, we applied the influenza positivity of respiratory samples tested in six SARI surveillance sentinel hospitals to the hospitalizations and deaths from the records with ICD 10 codes from influenza and pneumonia. RESULTS: Annually, 5320 people are hospitalized for influenza and 447 die for this cause. The annual influenza associated hospitalization rate for the period was 71.5/100 000 person-year for <5 years old, 11.8/100 000 person-year for people between 5 and 64 years old; and 156.0/100 000 person-year for >=65 years. The annual mortality rate for the period was 0.08/100 000 person-year for <5 years; 0.3/100 000 person-year for people between 5 and 64 years; and 22.8/100 000 person-year for >=65 years. CONCLUSIONS: This is the first study of influenza burden in Chile. Every year an important quantity of hospitalizations and deaths result from influenza infection. In countries in temperate zones, it is important to know the burden of influenza in order to prepare the health care network and to assess preventive intervention currently in practice and the new ones to implementing. PMID- 29446232 TI - Bmal1 knockdown suppresses wake and increases immobility without altering orexin A, corticotrophin-releasing hormone, or glutamate decarboxylase. AB - OBJECTIVE: To determine the effect of Bmal1 knockdown (KD) on sleep, activity, immobility, hypothalamic levels of orexin, corticotrophin-releasing hormone (CRH), and GABAergic glutamate decarboxylase (GAD). METHODS: We used Bmal1 siRNA, or control siRNA intracerebroventricular (ICV) injection to knock down Bmal1 in C57BL/6 mice. Sleep polysomnography, wheel-running activity, and tail suspension test were performed. Polysomnographic (PSG) recordings in both groups were preceded by ICV injection made during both the light phase and the dark phase. We also measured brain orexin A and CRH using an ELISA and measured GAD using immunoblotting. RESULTS: Compared with control group, Bmal1 KD group had reduced wheel activity and increased immobility. Compared with control, the Bmal1 KD group had reduced wheel activity and increased immobility. During the first 24 hours after treatment, we observed that control siRNA induced a much greater increase in sleep during the dark phase, which was associated with lower orexin levels. However, beginning 24 hours after treatment, we observed an increase in sleep and a decrease in time spent awake during the dark phase in the Bmal1 KD group. These changes were not associated with changes in brain levels of orexin A, CRH, or GAD. CONCLUSION: Bmal1 KD led to reduced activity, increased immobility, and dramatic reduction in time spent awake as well as an increase in sleep during the dark phase. Early after injection, there was a slight change in sleep but brain levels of orexin, CRH, and GAD remain unchanged. Control siRNA also affected sleep associated with changes in orexin levels.

AB - BACKGROUND: Estimates of influenza disease burden are broadly useful for public health, helping national and local authorities monitor epidemiologic trends, plan and allocate resources, and promote influenza vaccination. Historically, estimates of the burden of seasonal influenza in the United States, focused mainly on influenza-related mortality and hospitalization, were generated every few years. Since the 2010-2011 influenza season, annual US influenza burden estimates have been generated and expanded to include estimates of influenza related outpatient medical visits and symptomatic illness in the community. METHODS: We used routinely collected surveillance data, outbreak field investigations, and proportions of people seeking health care from survey results to estimate the number of illnesses, medical visits, hospitalizations, and deaths due to influenza during six influenza seasons (2010-2011 through 2015-2016). RESULTS: We estimate that the number of influenza-related illnesses that have occurred during influenza season has ranged from 9.2 million to 35.6 million, including 140 000 to 710 000 influenza-related hospitalizations. DISCUSSION: These annual efforts have strengthened public health communications products and supported timely assessment of the impact of vaccination through estimates of illness and hospitalizations averted. Additionally, annual estimates of influenza burden have highlighted areas where disease surveillance needs improvement to better support public health decision making for seasonal influenza epidemics as well as future pandemics. PMID- 29446228 TI - Integrins promote axonal regeneration after injury of the nervous system. AB - Integrins are cell surface receptors that form the link between extracellular matrix molecules of the cell environment and internal cell signalling and the cytoskeleton. They are involved in several processes, e.g. adhesion and migration during development and repair. This review focuses on the role of integrins in axonal regeneration. Integrins participate in spontaneous axonal regeneration in the peripheral nervous system through binding to various ligands that either inhibit or enhance their activation and signalling. Integrin biology is more complex in the central nervous system. Integrins receptors are transported into growing axons during development, but selective polarised transport of integrins limits the regenerative response in adult neurons. Manipulation of integrins and related molecules to control their activation state and localisation within axons is a promising route towards stimulating effective regeneration in the central nervous system. PMID- 29446234 TI - A natural antioxidant, tannic acid mitigates iron-overload induced hepatotoxicity in Swiss albino mice through ROS regulation. AB - Tannic acid (TA), a water soluble natural polyphenol with 8 gallic acids groups, is abundantly present in various medicinal plants. Previously TA has been investigated for its antimicrobial and antifungal properties. Being a large polyphenol, TA chelates more than 1 metal. Hence TA has been explored for potent antioxidant activities against reactive oxygen species (ROS), reactive nitrogen species (RNS) and as iron chelator in vitro thereby mitigating iron-overload induced hepatotoxicity in vivo. Iron dextran was injected intraperitoneally in Swiss albino mice to induce iron-overload triggered hepatotoxicity, followed by oral administration of TA for remediation. After treatment, liver, spleen, and blood samples were processed from sacrificed animals. The liver iron, serum ferritin, serum markers, ROS, liver antioxidant status, and liver damage parameters were assessed, followed by histopathology and protein expression studies. Our results show that TA is a prominent ROS and RNS scavenger as well as iron chelator in vitro. It also reversed the ROS levels in vivo and restricted the liver damage parameters as compared to the standard drug, desirox. Moreover, this natural polyphenol exclusively ameliorates the histopathological and fibrotic changes in liver sections reducing the iron-overload, along with chelation of liver iron and normalization of serum ferritin. The protective role of TA against iron-overload induced apoptosis in liver was further supported by changed levels of caspase 3, PARP as well as Bax/BCl-2 ratio. Thus, TA can be envisaged as a better orally administrable iron chelator to reduce iron-overload induced hepatotoxicity through ROS regulation. PMID- 29446235 TI - Quantitative evaluation of the performance of different deformable image registration algorithms in helical, axial, and cone-beam CT images using a mobile phantom. AB - The goal of this project is to investigate quantitatively the performance of different deformable image registration algorithms (DIR) with helical (HCT), axial (ACT), and cone-beam CT (CBCT). The variations in the CT-number values and lengths of well-known targets moving with controlled motion were evaluated. Four DIR algorithms: Demons, Fast-Demons, Horn-Schunck and Lucas-Kanade were used to register intramodality CT images of a mobile phantom scanned with different imaging techniques. The phantom had three water-equivalent targets inserted in a low-density foam with different lengths (10-40 mm) and moved with adjustable motion amplitudes (0-20 mm) and frequencies (0-0.5 Hz). The variations in the CT number level, volumes and shapes of these targets were measured from the spread out of the CT-number distributions. In CBCT, most of the DIR algorithms were able to produce the actual lengths of the mobile targets; however, the CT-number values obtained from the DIR algorithms deviated from the actual CT-number of the targets. In HCT, the DIR algorithms were successful in deforming the images of the mobile targets to the images of the stationary targets producing the CT number values and lengths of the targets for motion amplitudes <20 mm. Similarly in ACT, all DIR algorithms produced the actual CT-number values and lengths of the stationary targets for low-motion amplitudes <15 mm. The optical flow-based DIR algorithms such as the Horn-Schunck and Lucas-Kanade performed better than the Demons and Fast-Demons that are based on attraction forces particularly at large motion amplitudes. In conclusion, most of the DIR algorithms did not reproduce well the CT-number values and lengths of the targets in images that have artifacts induced by large motion amplitudes. The deviations in the CT number values and variations in the volume of the mobile targets in the deformed CT images produced by the different DIR algorithms need to be considered carefully in the treatment planning for accurate dose calculation dose coverage of the tumor, and sparing of critical structures.

AB - Social support at work is considered useful in treating job-related stress, and supervisors' emotional support has been found to be the most effective source of support at work. But an understanding of what elements make employees use supervisors as a source of emotional support is lacking. The present qualitative study included in-depth interviews with 24 teachers and 12 principals and a focus group with 12 school counsellors. The findings pointed at 2 groups of determinants of subordinates' intentions of asking socioemotional help from supervisors. The structural-organizational factors included low formalization structure, supportive and open work climate, shared goals, and manager's professional expertise; the dyadic factors included quality of relationship and demographic similarity. The determinants reflected different dimensions of psychological distance forming a close construal level that played a central part in employees' viewing the supervisor as an accessible socioemotional resource. The role of construal fit is discussed. PMID- 29446237 TI - Going through the motions: incorporating movement analyses into disease research. AB - Though epidemiology dates back to the 1700s, most mathematical representations of epidemics still use transmission rates averaged at the population scale, especially for wildlife diseases. In simplifying the contact process, we ignore the heterogeneities in host movements that complicate the real world, and overlook their impact on spatiotemporal patterns of disease burden. Movement ecology offers a set of tools that help unpack the transmission process, letting researchers more accurately model how animals within a population interact and spread pathogens. Analytical techniques from this growing field can also help expose the reverse process: how infection impacts movement behaviours, and therefore other ecological processes like feeding, reproduction, and dispersal. Here, we synthesise the contributions of movement ecology in disease research, with a particular focus on studies that have successfully used movement-based methods to quantify individual heterogeneity in exposure and transmission risk. Throughout, we highlight the rapid growth of both disease and movement ecology and comment on promising but unexplored avenues for research at their overlap. Ultimately, we suggest, including movement empowers ecologists to pose new questions, expanding our understanding of host-pathogen dynamics and improving our predictive capacity for wildlife and even human diseases. PMID- 29446238 TI - Bacterial microleakage at the abutment-implant interface, in vitro study. AB - INTRODUCTION: In implant rehabilitation, a microspace is created at the abutment implant interface (AII). Previous research has shown that oral microbiome can proliferate in this microspace and affect periimplant tissues, causing inflammation in peri-implant tissues. Preventing microbial leakages through the AII is therefore an important goal in implantology. OBJECTIVE: To determine the presence of marginal bacterial microleakage at the AII according to the torque applied to the prosthetic implant in vitro. MATERIAL AND METHODS: Twenty-five Ticare Inhex internal conical implants (MG Mozo-Grau, Valladolid, Espana) were connected to a prosthetic abutment using torques of <10, 10, 20, 30, and 30 N and then sealed. The samples were submitted to cycles of occlusal loads and thermocycling, then one sample of each group was observed by micro TC, while the rest were mounted on devices according to the bacterial leakage model with Porphyromonas gingivalis. RESULTS: Bacterial leakage was observed only in the <10 and 10 N torque samples, and the same groups presented poor abutment/implant adjustment as determined by micro-CT. CONCLUSION: The different torques applied to the abutment-implant system condition the bacterial leakage at the implant interface. No microleakage was observed at 20 and 30 N.

AB - An ion mobility quadrupole time-of-flight mass spectrometry-based pesticide suspect screening methodology was developed and validated covering 20 plant derived food matrices deriving from six commodity groups of different complexity according to the actual European Commission document SANTE/11813/2017 applying a QuEChERS sample preparation protocol. The method combines ultra-performance liquid chromatography, traveling wave ion mobility, and quadrupole time-of-flight mass spectrometry. Besides the determination of the physicochemical property collision cross-section and the establishment of a corresponding scientific suspect screening database comprising 280 pesticides for several pesticides, different protomers, sodium adducts, as well as dimers were identified in ion mobility spectrometry traces. Additionally, collision cross-section values were included in the validation requirements regarding chromatography and mass spectrometry for the detection of pesticides. A collision cross-section value window was analyzed within a tolerable error of +/-2%. For this cross-matrix validation, screening detection limits were determined at concentration levels of 0.100 mg/kg (84% of the original pesticide scope), 0.010 mg/kg (56%), and 0.001 mg/kg (21%). By application of ion mobility spectrometry, the compound identification was improved due to independence of commodity of concern and concentration levels of analyte molecules, as false assignments are reduced by application of a collision cross-section range.

AB - Successful prevention of pressure ulcers is the end product of a complex series of care processes including, but not limited to, the assessment of vulnerability to pressure damage; skin assessment and care; nutritional support; repositioning; and the use of beds, mattresses, and cushions to manage mechanical loads on the skin and soft tissues. The purpose of this review was to examine where and how Statistical Process Control (SPC) measures have been used to assess the success of quality improvement initiatives intended to improve pressure ulcer prevention. A search of 7 electronic bibliographic databases was performed on May 17th, 2017, for studies that met the inclusion criteria. SPC methods have been reported in 9 publications since 2010 to interpret changes in the incidence of pressure ulcers over time. While these methods offer rapid interpretation of changes in incidence than is gained from a comparison of 2 arbitrarily selected time points pre- and post-implementation of change, more work is required to ensure that the clinical and scientific communities adopt the most appropriate SPC methods. PMID- 29446243 TI - Reproductive health in women following abdominal organ transplant. AB - Fertility is commonly impaired in women with end-stage kidney and liver disease, although most women will have restoration of fertility within 1 year of transplant. Family planning is therefore critical to discuss with reproductive aged transplant recipients in the early posttransplant period, in order to ensure timely initiation of contraception, and optimal timing for conception. For women seeking pregnancy, the risks to the mother, graft, and baby should be discussed, including evaluation of immunosuppression safety and potential for adjusting medications prior to conception. With an increasing number of transplant patients now breastfeeding, immunosuppression safety in lactation continues to carry great importance. PMID- 29446245 TI - Differential metabolic effects of constant moderate versus high intensity interval training in high-fat fed mice: possible role of muscle adiponectin. AB - Exercise regimens may have differing effects in the presence of obesity. In addition to being fat derived, adiponectin has recently been described as a myokine that regulates insulin sensitivity, which may link to exercise-related metabolic benefits in obesity. Whether skeletal muscle adiponectin varies in different exercise modalities is unclear. This study investigated the comparative effects of 10 weeks of endurance constant-moderate intensity exercise (END) with high intensity interval training (HIIT), on metabolic outcomes, including muscle adiponectin in a mouse model of diet-induced obesity. Ten-week-old male C57BL/6 mice were fed a high-fat diet (HFD) (45% FAT) or standard CHOW diet ab libitum and underwent one of three training regimes: (1) no exercise, (2) END, or (3) HIIT (8 bouts of 2.5 min with eight periods of rest of 2.5 min) for 10 weeks (3 * 40 min sessions/week). Chow-fed mice acted as controls. Compared with HFD alone, both training programs similarly protected against body weight gain (HFD = 45 +/- 2; END = 37 +/- 2; HIIT = 36 +/- 2 g), preserved lean/fat tissue mass ratio (HFD = 0.64 +/- 0.09; END = 0.34 +/- 0.13; HIIT = 0.33 +/- 0.13), and improved blood glucose excursion during an insulin tolerance test (HFD = 411 +/- 54; END = 350 +/- 57; HIIT = 320 +/- 66 arbitrary units [AU]). Alterations in fasting glycemia, insulinemia, and AST/ALT ratios were prevented only by END. END, but not HIIT increased skeletal muscle adiponectin mRNA (14-fold; P < 0.05) and increased protein content of high molecular weight (HMW) adiponectin (3.3-fold), whereas HIIT induced a milder increase (2.4-fold). Compared with HFD, neither END nor HIIT altered circulating low (LMW) or high (HMW) molecular weight adiponectin forms. Furthermore, only END prevented the HFD downregulation of PGC1alpha (P < 0.05) mRNA levels downstream of muscle adiponectin. These data show that different training programs affect muscle adiponectin to differing degrees. Together these results suggest that END is a more effective regimen to prevent HFD-induced metabolic disturbances in mice. PMID- 29446246 TI - Improvement of cardiomyocyte function by in vivo hexarelin treatment in streptozotocin-induced diabetic rats. AB - Diabetic cardiomyopathy is characterized by diastolic and systolic cardiac dysfunction, yet no therapeutic drug to specifically treat it. Hexarelin has been demonstrated to improve heart function in various types of cardiomyopathy via its receptor GHS-R. This experiment aims to test the effect of hexarelin on cardiomyocytes under experimental diabetes. Streptozotocin (STZ, 65 mg/kg) induced diabetic rat model was employed with vehicle injection group as control. Daily hexarelin (100 MUg/kg) treatment was performed for 2 weeks after 4-week STZ induced diabetes. Cardiomyocytes were isolated by enzyme treatment under O2 saturated perfusion for single-cell shortening, [Ca2+ ]i transient, and electrophysiology recordings. GHS-R expression and apoptosis-related signaling proteins Bax, Bcl-2, caspase-3 and 9, were assessed by western blot. Experimental data demonstrated a reduced cell contraction and relaxation in parallel with depressed rise and fall of [Ca2+ ]i transients in diabetic cardiomyocytes. Hexarelin reversed the changes in both contraction and [Ca2+ ]i . Action potential duration and transient outward potassium current (Ito ) density were dramatically increased in diabetic cardiomyocytes and hexarelin treatment reverse such changes. Upregulated GHS receptor (GHS-R) expression was observed in both control and diabetic groups after hexarelin treatment, which also caused antiapoptotic changes of Bax, Bcl-2, caspase-3 and 9 expression. In STZ-induced diabetic rats, hexarelin is able to improve cardiomyocyte function through recovery of Ito K+ currents, intracellular Ca2+ homeostasis and antiapoptotic signaling pathways.

AB - BACKGROUND: Serological responses to revaccination against hepatitis B virus (HBV) are unclear in HIV-positive adults who had undergone neonatal HBV vaccination and whose antibodies against HBV had waned in the era of combination antiretroviral therapy (cART). METHODS: Between 2000 and 2017, 666 HIV-positive men who have sex with men (MSM) who were born after 1986, when nationwide neonatal HBV vaccination programme was implemented in Taiwan, were included for analyses. A serological response was defined when a hepatitis B surface antibody (anti-HBs) titre >=10 mIU/mL was measured 4-24 weeks after the third dose of HBV vaccination. RESULTS: During the study period, 295 (48.7%) HIV-positive MSM (mean age, 23.2 years) who had lost HBV seroprotection were eligible for revaccination; 171 (58.0%) received at least 1 dose (20-MUg) of HBV vaccine and 116 (39.3%) completed the 3-dose schedule. The serological response rate to 3 doses of HBV revaccination was 74.0% and the rate of high-titre response (anti-HBs titre >=100 mIU/mL) was 46.0%. The CD4 count before the first dose (per 50-cell/MUL increment, adjusted odds ratio, 1.14; 95% confidence interval, 1.01-1.29) was positively associated with the serological response. The incident rate of HBV infection was 9.2 per 1000 person-years of follow-up among the patients who were non-responders after revaccination. CONCLUSIONS: Despite HBV vaccination in the neonatal period, the serological response rate to HBV revaccination in HIV positive MSM was modest and could wane rapidly. Regular testing of anti-HBs should be integrated into the HIV care despite cART containing HBV-active agents. PMID- 29446250 TI - How do Small Groups Promote Behaviour Change? An Integrative Conceptual Review of Explanatory Mechanisms. AB - BACKGROUND: Small groups are used to promote health, well-being, and personal change by altering members' perceptions, beliefs, expectations, and behaviour patterns. An extensive cross-disciplinary literature has articulated and tested theories explaining how such groups develop, function, and facilitate change. Yet these theoretical understandings are rarely applied in the development, description, and evaluation of health-promotion, group-based, behaviour-change interventions. METHODS: Medline database, library catalogues, search engines, specific journals and reference lists were searched for relevant texts. Texts were reviewed for explanatory concepts or theories describing change processes in groups, which were integrated into the developing conceptual structure. This was designed to be a parsimonious conceptual framework that could be applied to design and delivery. RESULTS: Five categories of interacting processes and concepts were identified and defined: (1) group development processes, (2) dynamic group processes, (3) social change processes, (4) personal change processes, and (5) group design and operating parameters. Each of these categories encompasses a variety of theorised mechanisms explaining individual change in small groups. CONCLUSION: The final conceptual model, together with the design issues and practical recommendations derived from it, provides a practical basis for linking research and theory explaining group functioning to optimal design of group-based, behaviour-change interventions. PMID- 29446251 TI - A novel technique for en bloc kidney transplantation from infant donors with extremely low body weight by using the distal abdominal aorta as an outflow tract. AB - Pediatric kidney donors remain underutilized due to the high risk of postoperative thrombosis. To address this problem, we developed a novel en bloc kidney transplantation technique using donor thoracic aorta and the distal abdominal aorta as inflow and outflow tracts, respectively. Briefly, eight kidneys from deceased infant donors under five months old and with low body weight (1.9-4.9 kg) were transplanted en bloc into four pediatric and four adult patients. The donor's common iliac artery or external iliac artery was anastomosed to the recipient's distal external iliac artery or inferior epigastric artery, respectively, as an outflow tract. Recipients received basiliximab or antithymocyte globulin as induction therapy followed by tacrolimus, mycophenolate mofetil, and prednisone but without prophylactic anticoagulation. Delayed graft function was observed in one patient but was reversed at 90 days posttransplant. Two patients had urine leakage, which was cured by conservative treatment. Two recipients developed lung infections that eventually cleared. No patients experienced posttransplant vascular thrombosis. After 1-1.5 years of follow-up, all patients are well and have normal serum creatinine levels. In conclusion, this novel en bloc kidney transplantation technique using a modified arterial inflow and outflow tract can prevent vascular thrombosis and provide adequate graft function. PMID- 29446252 TI - What is the effect of exercise on wound healing in patients with venous leg ulcers? A systematic review. AB - Standard best practice for the treatment of venous leg ulcers (VLUs) is compression bandaging of the lower leg to reduce hydrostatic pressure. There is considerable variation in reported healing rates when using this gold-standard approach; therefore, a systematic and robust evaluation of other interventions is required. Exercise interventions, in addition to standard compression therapy, could improve wound-healing time and prevent their recurrence. We have conducted a systematic review to examine the effects of exercise on wound characteristics, including time to heal, size and recurrence, pain, quality of life, adverse events, and economic outcomes. This review was registered with PROSPERO 2016:CRD42016046407. A systematic search of Ovid Medline, Ovid EMBASE, Ovid CINAHL, The Cochrane Library, PsycINFO, Web of Science, and PEDro was conducted on January 30, 2017, for randomised control trials to examine the effects of exercise on time to heal, size and recurrence, pain, quality of life, adverse events, and economic outcomes. Six studies met the inclusion criteria, but all had design flaws leading to biases, most commonly performance and selective reporting bias. Three studies compared a progressive resistance exercise programme (PREG) plus compression with compression alone for a period of 12 weeks. Low-quality evidence indicates the following: possibly no difference in the proportion of ulcers healed (risk ratio [RR] 1.14, 95% CI 0.71 to 1.84, I2 36%; 3 trials, 116 participants); probably no difference in quality of life (mean difference [MD] 3 points better on 100 point scale with exercise, 95% CI -1.89 to 7.89, 1 trial, 59 participants); possible increase in the risk of adverse events with exercise (OR 1.32, 95% CI 0.95 to 1.85, 1 RCT, 40 participants); and no difference in ankle range of motion and calf muscle pump. Evidence was downgraded due to susceptibility to bias and imprecision. Recurrence, pain, and economic outcomes were not measured in these trials, and time to healing was measured but not fully reported in 1 trial. We are uncertain of the effects of other interventions (community-based exercise and behaviour modification, ten thousand steps, supervised vs unsupervised exercise) due to the availability of low- or very low-quality evidence only from single trials. The review highlights the need for further research, with larger sample sizes, to properly address the significance of the effect of exercise on VLU wound characteristics.

AB - Surgical results for intrahepatic cholangiocarcinoma (ICC) remain unsatisfactory due to the high rate of recurrence. Here, we investigated that the expression and roles of tripartite motif-containing protein 44 (TRIM44) in human ICCs. Firstly, TRIM44 expression was analyzed in several kinds of cancers by referring to public Oncomine database, and the expressions of TRIM44 mRNA and protein were tested in ICC and corresponding paratumorous tissues. Secondly, functions and mechanisms of TRIM44 in ICC cells were further evaluated by TRIM44 interference and cDNA transfection. Finally, the prognostic role of TRIM44 was assessed by Kaplan-Meier and Cox regression. We found that TRIM44 expression was upregulated in ICC tissues compared with corresponding paratumorous tissues, which were consistent with the results from the public cancer database. Knockdown of TRIM44 repressed the invasion and migration of ICC cells, while increased the ICC cell apoptosis. Additionally, high level of TRIM44 was shown to induce ICC cell epithelial to mesenchymal transition (EMT). Mechanistically, a high level of TRIM44 was found to activate MAPK signaling, and a MEK inhibitor, AZD6244, reversed cell EMT and apoptosis endowed by TRIM44 overexpression. Clinically, TRIM44 expression was positively associated with large tumor size (P = 0.035), lymphatic metastasis (P = 0.008) and poor tumor differentiation (P = 0.036). Importantly, patients in TRIM44high group had shorter overall survival and higher cumulative rate of recurrence than patients in TRIM44low group. Our results suggest elevated TRIM44 promotes ICC development by inducing cell EMT and apoptosis resistance, and TRIM44 is a valuable prognostic biomarker and promising therapeutic target of ICC. PMID- 29446254 TI - Heart failure: a weak link in CHA2 DS2 -VASc. AB - AIMS: In atrial fibrillation, stroke risk is assessed by the CHA2 DS2 -VASc score. Heart failure is included in CHA2 DS2 -VASc, but the rationale is uncertain. Our objective was to test if heart failure is a risk factor for stroke, independent of other risk factors in CHA2 DS2 -VASc. METHODS AND RESULTS: We studied 300 839 patients with atrial fibrillation in the Swedish Patient Register 2005-11. Three definitions of heart failure were used in order to assess the robustness of the results. In the main analysis, heart failure was defined by a hospital discharge diagnosis of heart failure as first or second diagnosis and a filled prescription of a diuretic within 3 months before index + 30 days. The second definition counted first or second discharge diagnoses <1 year before index + 30 days and the third definition any heart failure diagnosis in open or hospital care before index + 30 days. Associations with outcomes were assessed with multivariable Cox analyses. Patients with heart failure were older (80.5 vs. 74.0 years, P < 0.001) and had higher CHA2 DS2 -VASc score (4.4 vs. 2.7, P < 0.001). The 1 year incidence of ischaemic stroke without warfarin was 4.4% with heart failure and 3.1% without. Adjustment for the cofactors in CHA2 DS2 -VASc eradicated the difference in stroke risk between patients with and without heart failure (hazard ratio 1.01 with 95% confidence interval 0.96-1.05). The area under the receiver operating characteristic curve for CHA2 DS2 -VASc was not improved by points for heart failure. CONCLUSIONS: A clinical diagnosis of heart failure was not an independent risk factor for stroke in patients with atrial fibrillation, which may have implications for anticoagulation management.

AB - BACKGROUND: Although various genes and genomic regions were described as of susceptibility for nonsyndromic oral clefts (NOC), recent reports have demonstrated significant interethnic variations in the genetic predisposition, a situation that affects the Brazilian population, one of the most admixed populations in the world. Therefore, the purpose of this review was to describe the available information on genetic risk markers for NOC in the Brazilian population. METHODS: A systematic search of the literature was performed using LILACS, LIVIVO, PubMed, Scopus, and Web of Science databases, and studies that investigated genetic susceptibility markers for NOC in the Brazilian population were retrieved. Markers with enough statistical data were subjected to meta analysis using random- or fixed-effects model with odds ratio (OR) and 95% confidence intervals (95% CI) as effect measures. RESULTS: Forty-nine studies conducted since 1999 were found, and in these 114 markers were evaluated throughout case-control or family-based approaches. Most of the studies were conducted with patients affected by nonsyndromic cleft lip with or without cleft palate (NSCL +/- P), and 79 markers (69.3%) were evaluated by a single study only. Meta-analysis was performed with nine markers, and the most promising results were obtained for IRF6 (rs642961), 8q24 (rs987525 and rs1530300) and MTHFR (rs1801133), which were associated with increased risk for NSCL +/- P, and for BMP4 (rs17563) that showed a protective effect for NSCL +/- P. CONCLUSION: A large number of genetic markers distributed in several genes/loci was associated with NOC in the Brazilian population, but in general the original studies included limited number of samples and unsatisfactory protocols. The classical risk markers located in IRF6 and 8q24 showed promising results as well as rs1801133 in MTHFR and rs17563 in BMP4, and they should be validated in larger and multicenter studies taking in consideration the variations in the miscegenation of Brazilian population. PMID- 29446256 TI - Using a Vancomycin PBPK Model in Special Populations to Elucidate Case-Based Clinical PK Observations. AB - Simultaneous changes in several physiological factors may contribute to the large pharmacokinetic (PK) variability of vancomycin. This study was designed to systematically characterize the effects of multiple physiological factors to the altered PK of vancomycin observed in special populations. A vancomycin physiologically based pharmacokinetic (PBPK) model was developed as a PK simulation platform to quantitatively assess the effects of changes in physiologies to the PK profiles. The developed model predicted the concentration time profiles in healthy adults and diseased patients. The implementation of developmental changes in both renal and non-renal elimination pathways to the pediatric model improved the predictability of vancomycin clearance. Simulated PK profiles with a 50% decrease in cardiac output (peak plasma concentration (Cmax ), 59.9 ng/mL) were similar to those observed in patients before bypass surgery (Cmax , 55.1 ng/mL). The PBPK modeling of vancomycin demonstrated its potential to provide mechanistic insights into the altered disposition observed in patients who have changes in multiple physiological factors. PMID- 29446257 TI - Utilization of direct smears of thyroid fine-needle aspirates for ancillary molecular testing: A comparison of two proprietary testing platforms. AB - BACKGROUND: Ancillary molecular testing has been recommended for thyroid fine needle aspirates (FNA) with indeterminate cytologic diagnoses. Rosetta Genomics and Interpace Diagnostics have developed assays that can utilize direct smears as the testing substrate. METHODS: A retrospective study of indeterminate thyroid FNAs with known histologic follow-up was performed. One Diff-Quik-stained smear and one Papanicolaou-stained smear with similar cellularity (at least 60-100 lesional cells) from each case were sent to Rosetta and Interpace, respectively, for analysis. The results were directly compared and correlated with the final histopathology. Neither company was aware of the follow-up histologic findings in these cases. RESULTS: A total of 10 thyroid FNAs were identified from our 2015 files. The cytologic diagnoses included follicular lesion of undetermined significance (FLUS, n = 5), follicular neoplasm/suspicious for follicular neoplasm (FN/SFN, n = 4), and suspicious for malignancy (SM, n = 1). Of the seven cases with benign histology, six smears were classified as benign by the RosettaGX microRNA classifier, and one case was designated as suspicious. Five cases were negative by both ThyGenX oncogene panel and ThyraMIR microRNA classifier. One case was negative by ThyGenX and positive on follow-up ThyraMIR, and one case was positive for KRAS mutation and positive on ThyraMIR. Both the RosettaGX and ThyGenX/ThyraMIR tests demonstrated positive results for the three histologically malignant cases. CONCLUSION: This study demonstrates that two molecular testing platforms performed equally well using our stained direct smears. Both molecular tests revealed a 100% negative predictive rate. RosettaGX showed a 75% positive predictive value in comparison to 60% for ThyGenX/ThyraMIR. PMID- 29446258 TI - Corrigendum. PMID- 29446259 TI - Corrigendum.

AB - The photoresponsive azobenzene-tethered DNAs have received growing experimental attention because of their potential applications in biotechnology and nanotechnology; however, little is known about the initial photoisomerization of azobenzene in these systems. Herein we have employed quantum mechanics/molecular mechanics (QM/MM) methods to explore the photoisomerization dynamics of an azobenzene-tethered DNA duplex. We find that in the S1 state the trans-cis photoisomerization path is much steeper in DNA than in vacuo, which makes the photoisomerization much faster in the DNA environment. This acceleration is primarily caused by complex steric interactions between azobenzene and the nearby unpaired thymine nucleobase, which also change the photoisomerization mechanism of azobenzene in the DNA duplex. PMID- 29446261 TI - Enhanced linear-array photoacoustic beamforming using modified coherence factor. AB - Photoacoustic imaging (PAI) is a promising medical imaging modality providing the spatial resolution of ultrasound imaging and the contrast of optical imaging. For linear-array PAI, a beamformer can be used as the reconstruction algorithm. Delay and-sum (DAS) is the most prevalent beamforming algorithm in PAI. However, using DAS beamformer leads to low-resolution images as well as high sidelobes due to nondesired contribution of off-axis signals. Coherence factor (CF) is a weighting method in which each pixel of the reconstructed image is weighted, based on the spatial spectrum of the aperture, to mainly improve the contrast. We demonstrate that the numerator of the formula of CF contains a DAS algebra and propose the use of a delay-multiply-and-sum beamformer instead of the available DAS on the numerator. The proposed weighting technique, modified CF (MCF), has been evaluated numerically and experimentally compared to CF. It was shown that MCF leads to lower sidelobes and better detectable targets. The quantitative results of the experiment (using wire targets) show that MCF leads to for about 45% and 40% improvement, in comparison with CF, in the terms of signal-to-noise ratio and full-width-half-maximum, respectively.

AB - Optical imaging techniques are widely used for in vivo preclinical studies, and it is well known that the Geant4 Application for Emission Tomography (GATE) can be employed for the Monte Carlo (MC) modeling of light transport inside heterogeneous tissues. However, the GATE MC toolkit is limited in that it does not yet include optical lens implementation, even though this is required for a more realistic optical imaging simulation. We describe our implementation of a biconvex lens into the GATE MC toolkit to improve both the sensitivity and spatial resolution for optical imaging simulation. The lens implemented into the GATE was validated against the ZEMAX optical simulation using an US air force 1951 resolution target. The ray diagrams and the charge-coupled device images of the GATE optical simulation agreed with the ZEMAX optical simulation results. In conclusion, the use of a lens on the GATE optical simulation could improve the image quality of bioluminescence and fluorescence significantly as compared with pinhole optics. PMID- 29446263 TI - Pulsed terahertz imaging of breast cancer in freshly excised murine tumors. AB - This paper investigates terahertz (THz) imaging and classification of freshly excised murine xenograft breast cancer tumors. These tumors are grown via injection of E0771 breast adenocarcinoma cells into the flank of mice maintained on high-fat diet. Within 1 h of excision, the tumor and adjacent tissues are imaged using a pulsed THz system in the reflection mode. The THz images are classified using a statistical Bayesian mixture model with unsupervised and supervised approaches. Correlation with digitized pathology images is conducted using classification images assigned by a modal class decision rule. The corresponding receiver operating characteristic curves are obtained based on the classification results. A total of 13 tumor samples obtained from 9 tumors are investigated. The results show good correlation of THz images with pathology results in all samples of cancer and fat tissues. For tumor samples of cancer, fat, and muscle tissues, THz images show reasonable correlation with pathology where the primary challenge lies in the overlapping dielectric properties of cancer and muscle tissues. The use of a supervised regression approach shows improvement in the classification images although not consistently in all tissue regions. Advancing THz imaging of breast tumors from mice and the development of accurate statistical models will ultimately progress the technique for the assessment of human breast tumor margins.

AB - In the article there are given results of the evaluation of non-carcinogenic risks for the health of the child population residing in different areas (districts) of the city of Kazan with the aim of the subsequent comprehensive assessment of the pollutants in drinking water. Assessment of the risk for the human health was performed correspondingly to with the P 2.1.10.1920-04 for oral route of exposure in accordance to the chemical composition of drinking water with account for the standard and regional factors of the exposure. The results of the risk assessment under the consumption of drinking tap water by the child population with localized place of residence permit to reveal areas with a high level of health risk in the city. The screening assessment of carcinogenic risk due to the consumption of chemicals with drinking water revealed differences in regional and standard values of the exposure factors. This affects both on the value of the chronic average daily intake of chemical contaminants in drinking water and the level of risk under the consumption of drinking water by the child population.

PMID- 29446267 TI - Skin irritation from a facial mask in Class III malocclusion: evaluation of individual silicone chin cups in a group of 100 children. AB - BACKGROUND: Reverse headgear (a facial mask) is one of the most frequently used interceptive orthodontic devices in patients with Class III malocclusion. It is a simple device but may present some drawbacks related to pressure on the skin generated by the forehead and chin supports linked to the maxillary intraoral appliance by elastics. This can cause injury to the chin and lips. METHODS: Patients between 7 and 8 years of age were selected from the Unit of Pediatric Dentistry. Orthopedic therapy with a rapid palatal expander and reverse headgear was prescribed for all subjects. The patients were divided into two groups: those who used a facial mask without a silicone chin cup and those who used a facial mask with a silicone chin cup. RESULTS: Two-hundred subjects including 90 male patients and 110 female patients were enrolled. The groups that used a facial mask with and without a silicone chin cup included 100 patients each. The percentage of subjects without irritation was significantly greater in the group with a silicone chin cup than in the group without a silicone chin cup. CONCLUSIONS: The authors propose a simple and effective solution to prevent skin irritation on the chin caused by a facial mask. A chin mask is a custom solution that can prevent injury to the chin during treatment when coupled with facial mask therapy. PMID- 29446268 TI - Tooth color changes and sensitivity in patients undergoing dental bleaching with 10% hydrogen peroxide using customized trays or strips: a randomized clinical trial. AB - BACKGROUND: This paper aimed to compare the tooth color changes and sensitivity in patients undergoing dental bleaching with 10% hydrogen peroxide using customized trays or strips as delivering systems. METHODS: A total of 50 patients aged between 18-30 years old were assigned into two groups (N.=25) according to the bleaching treatment: tray (TB) or strips (SB). For both techniques, the patients underwent a 30-minute application of 10% hydrogen peroxide twice a day for seven days. Tooth color was evaluated before, 3 and 7 days of treatment, and 14 days after bleaching using a tooth color shade guide (VITA(r) shade). Tooth sensitivity was assessed using the Visual Analogue Scale (VAS). The values obtained from the color changes and tooth sensitivity were statistically analyzed (alpha=5%). RESULTS: For both groups, there was a significant difference on the tooth color before and after bleaching (P<0.001), although there was no significant difference between them (P=0.4215). The SB group exhibited a lower frequency of sensitivity (50.2%) compared to the TB group (70.2%) (P<0.001). However, the highest number of individuals reporting score 1 of sensitivity was found in the SB group (37.3%) compared to the TB group (20.9%) (P<0.001). For the other scores, there were no differences between the SB and TB groups, with results of 9.8% and 8.4% for score 2 (P=0.744) and 2.7% and 0.5% for score 3 (P=0.122). CONCLUSIONS: The bleaching effect of 10% hydrogen peroxide is not influenced by the delivering system (tray or strips). Even though the technique with strips was associated to a lower frequency of dental sensitivity, the peak level of pain was greater when compared to the technique using trays. PMID- 29446269 TI - A self-report joint damage and musculoskeletal disorders data among dentists: a cross-sectional study. AB - BACKGROUND: Musculoskeletal disorders (MSD) are an occupational health problem that demands a high cost and may also reduce the quality of life and productivity of the dentists. The aim of this study was to evaluate the prevalence of MSD and its association with self-reported joint damage in dentists from Sao Paulo (Brazil). METHODS: This was a cross-sectional study performed from two self administered questionnaires - the Nordic Musculoskeletal Questionnaire and the other containing demographic and occupational data - in 6072 dentists. Between April and May 2014, 5885 questionnaires were distributed via e-mail through Sao Paulo Regional Board of Dentistry (CRO-SP) and 187 in Congress and public offices. Multivariable logistic regression was used to assess the association between explanatory variables (sex, age, level of education, duration of practice in years, number of patients seen per day, previous receipt of information about ergonomics, physical activity, and the presence of joint damage) and MSD. RESULTS: Two hundred eighty-six valid questionnaires were returned. The prevalence of MSD was 63.6% (N.=182). Multivariable logistic regression showed that only the factor of self-reported joint damage has a significant association with MSD (OR 0.001; 95% CI: 0.000-0.007). Concerning the self-reported joint damage (60.1%), the carpal tunnel syndrome was the most frequent (13.2%). CONCLUSIONS: The prevalence of MSD in dentists from Sao Paulo is high, and carpal tunnel syndrome is the most common self-reported joint damage.

AB - BACKGROUND: The aim of this study was to compare the effects of acidulated phosphate fluoride (APF) gel, calcium phosphopeptide-amorphous calcium phosphate (CPP/ACP) paste alone and in combination with CO2 laser on the resistance of enamel to acid solubility. METHODS: Ninety enamel sections were obtained from 15 extracted teeth and were randomly assigned to six groups: 1) control group; 2) APF group; 3) CPP-ACP group; 4) CO2 laser group; 5) APF + CO2 group; and 6) CPP ACP + CO2 group. The specimens were individually demineralized in 0.1 M lactic acid solution with adjusted pH of 4.8 for 24h at 37 oC. The acid solubility was determined using atomic absorption spectrometry. Statistical analysis was done using one-way ANOVA and Tukey-Kramer post hoc test (P<0.05). RESULTS: The average extent of calcium ion released (ppm) was estimated as follow: group 1: 6.974+/ 1.757, group 2: 5.363+/-1.383, group 3: 6.962+/-1.489, group 4: 6.890+/-1.560, group 5: 4.803+/-1.080 and group 6: 6.789+/-1.218. Based on the between-group comparison results, group 2 and group 5 showed significant differences with the other groups. CONCLUSIONS: Under the studied conditions, only, the APF group alone and in combination with CO2 laser could decrease enamel acid solubility.

AB - In the article there is considered the substantiation of raise demands to the chemical composition of children's food and indices of their safety, with taking into account the immaturity of metabolic and physiological processes and limitations of "depot" of nutrients in babies. Based on research results of leading experts in the field of children's nutritiology and according to the recommendations of the Codex Alimentarius of the Commission of FAO/WHO, ESPGHAN Committee on Nutrition, the EFSA recommendations and EUDirectives there were specified requirements for the ingredient composition, content of essential components and indices of the nutritional value of substitutes for human milk and functional products for the nutrition of infants of the first year of life. There are shown stages of the development of the Russian system of hygienic requirements for baby food, and the direction of its harmonization with international and European standards, particularly for substitutes for human milk and products of dietary therapeutic and dietary preventive nutrition for babies. There are considered aspects of the introduction ofproducts and weaning food dishes into the food ration of infants. There is presented the classification ofproducts of children's food and the assortment of each group of weaning foods. There is provided the modern legislative framework in the field of the quality and safety for infant nutrition. There was shown the difference between domestic legislation and regulatory framework of the EurAsEC Customs Union of the European countries in the field offood products safety for children older three years. There are presented proposals on the creation of the single regulatory base within the framework of the EurAsEC Customs Union for control the quality and safety of all the baby foods.

AB - Based on the study of actual nutrition and availability of macroelements there was found that adult population of the city of Omsk was established to refer to the group at risk for the development of micronutrient deficiency associated with low content of a set of essential elements (copper, zinc, calcium, selenium) in the ration, being prior for correction.There was executed the hygienic substantiation developed the fermented acid milk bioproduct of a functional purpose "Bifidin" enriched with micronutrients, prior for the population of the Omsk region. Introduction of this bio-product into the ration allows to effectively correct disorders of the mineral status, that was manifested in a decline in the proportion of patients with insufficiency of calcium (from 37.9 to 24.1%; p = 0.013), copper (from 51.7 to 25.9%; p = 0.004), selenium (from 96.6 to 84.5%; p = 0.026), zinc (from 58.6 to 48.3% of the subjects; p = 0.264). Upon the completion of the prophylactic course (intake "Bifidin" of 200 ml for 60 days), there was noted the gain in the concentration in hair: calcium (by 24.4%; p=0.441), zinc (by 8.0%; p=0.0008), copper (by 8.8%; p < 0.001), selenium (by 41.5%; p < 0.001). There was established the efficacy of the use of bio-product "Bifidin" enriched with micronutrients for the improvement of the structure of nutrition and element status of the adult population of the city of Omsk. There was justified the extensive use of dairy products enriched with micronutrients both for the reduction of the prevalence of microelementoses and the improvement of the nutritional status.

AB - In the work there are considered results of the development of the multicomponent method of measurement of concentration of herbicides of various chemical nature under their joint presence in the water. There was justified the optimality of application of HPLC-DAD (the working wavelength of 240 nm) for the determination of levels of 10 active ingredients of herbicides of class of sulfonylurea (metsulfuron-methyl, nikosulfuron, sulfometuron-methyl, thifensulfuron-methyl, triflusulfuron-methyl), imidazolinone (imazapyr, imazethapyr), 2,6-Bis[(4,6 dimethoxy-2- pyrimidinyl)oxy]benzoic acid (bispyribac acid), triazol-pyrimidines (Penoxsulam), a benzoylpyrazole compound (Topramenzone). For the concentrating and cleaning of samples of water there were used cartridges for solid-phase extraction of Oasis HLB - the macro porous copolymer made on the basis of the balanced ratio of 2 monomers - lipophilic divinylbenzene and hydrophilic N vinylpirrolidone. The range of the detected concentrations in water was volatile between 0.0005 and 0.005 mg/L, values of standard deviation vary in the range of 1.8-3.9%. Chlorine-containing acidic herbicides were analyzed by the method of GC ECD and GC-MS (IE) after preliminary converting of compounds into flying derivatives with the use of diazomethane. Satisfactory extraction of substances from a water sample may be achieved by classical extraction in the system "liquid liquid" with the application of Methyl tert-butyl ester. For cleaning of the derivatized sample there were used cartridges for solid-phase extraction on the basis of silica gel. The range of the determination of 9 active ingredients referring to classes of phenoxy-acetic acid (2,4- D, MCPA), pyridinecarboxylic (aminopyiralid, picloram, clopyralid), benzoic acids (dicamba), benzothiadiazinone (bentazone), biphenyl ester (acifluorfen) and a chloroacetamide (acetochlor) - 0.0001-0.001 mg/L, SD values vary in the range of 1.8-33%.

AB - The paper presents the results of a study of the qualitative composition and quantity of pollutants in atmospheric air in the course of operational wear of the road surface, braking system and tire treads of automobiles. On the basis of field research in samples ofatmospheric air ofthe city of St. Petersburg there were identified compounds of heavy metals andpolycyclic aromatic hydrocarbons (PAHs). There was established the dependence of the level of air pollution on traffic flows in locations of the city. Pollutants were shown to enter the air environment mainly in the form offine dust particles. There was justified the need for the control ofproducts of wear the road traffic complex in the hygienic assessment of the quality of ambient air ofmegalopises.

AB - In the work there are presented results of studies on the validation of the gas chromatographic (GC) methodfor the determination of chlorothalonil residue amounts in peaches with the use of electron capture detector (ECD). For the analytical control there was selected such stone fruit crop as the peach, referring to the crops, the most contaminated with residue amounts ofpesticides. There was justified the necessity of the inclusion in the procedure of the detection of the method of confirmation, based on mass spectrometry detection (MSD) (the type of ionization - electron impact). The significant source of the obtaining of incorrect data in the identification with the use of ECD of ions are shown to be phthalates, visualized in the chromatogram as intense and/or broad peaks. Mass spectra of compounds of the class ofphthalates are characterized by the dominant peak of the ion with the value of (mass/ charge) 149, just on this peak the detection of low molecular weight phthalates occurs in various matrices, on the spectrum there are also recorded typical ions corresponding to fragments of radical residues. The combination of the use of various types of the detection allows to prove that the revealed response (detector signal) is caused just by the analyte, but not the impurities, and optionally to optimize chromatographic conditions towards to the obtaining reliable results. The lower limit of the quantitation of chlorothalonil in peach fruits accounts for 0.01 mg/kg, determined with a signal/noise ratio of 10. The range of measured concentrations is volatile between 0.01-0.1 mg/kg, recovery rate of chlorothalonil from samples of peaches, established according to results of the analysis of model samples with the introduction of the substance in four points along the detection range, was 84-102%, the SD value of the repeatability varies in the range of 2.0-5.8%.

AB - The aim of the study was the hygienic characteristics of the location of sewage pumping stations (SPSs) in the residential area of the city and the assessment of working conditions for the staff. The features of the technological process at the SPSs resulted in the formation of specific working conditions characterized by the presence of a cooling microclimate, noise production, technological vibration, air pollution by microorganisms. The assessment of working conditions has allowed to refer them to the 3 class (harmful working conditions) of the 2 and 3 degree. Preventive measures for SPSs should include the use of equipment for cleaning the air of working zone, having a combined odourremoving and microbicidal action; the automation of the labor process; the installation of additional equipment for filtering air circulating in workplaces and emitting into the atmosphere; provision of sealing equipment with the use of noise insulating materials.

AB - The aim is the study of the circulation, biological activity, persistent potential and genotypic characteristics of opportunistic Enterobacteriaceae of microbial community of the Lena River which is the one of the largest sources of water in Russia and Siberia. Gram-negative component of microbial community in the Lena River was mainly represented by Enterobacteriaceae (80%), including dominated Escherichia (dominant class) and Enterobacter and Klebsiella (subdominant class). In conditions of anthropogenic pollution there is a reorganization of microbial community of the Lena River in the direction of the increase in the proportion of opportunistic pathogens, their species diversity; there is a change of the biological activity of microorganisms, gains of share of strains characterized by antilysozyme activity, hemolytic activity, production DNase, phosphatase. The parameters of system "lysozyme-antilysozyme" are changing, the frequency of the occurrence of bacteria with antilysozyme activity is increasing. This shows the restructurization of the microbial community of water objects. Microorganisms of water objects in territories of anthropogenic pollution are characterized by multiple antibiotic resistance. The proportion of gram-negative opportunistic Enterobacteriaceae in microbial communities of water ecosystems determines the potential danger of water objects and the impact on the level of antibiotic resistance of bacteria. Opportunistic Enterobacteriaceae of microbial community of the Lena River near the city of Yakutsk are characterized by the presence of genetic determinants of pathogenicity (hlyA and sfaG). This is indicative of their potential epidemiological relevance. Microorganisms with high biological activity are markers of their epidemiological danger.

AB - This article describes results of the immunological study of school-aged children residing in cities with different levels of the technogenic air pollution. Children from cities with the highest level of the technogenic pollution had a high number of immature neutrophils (band cells) and eosinophils. The children living in these ecologically unfavorable areas have presented a reduction of T cell antigen receptor CD3, CD4, CD8, CD20, CD16, CD95. This indicates to that both T-cell and B-cell immunity is suppressed. The decline of the phagocytic function in neutrophils indicates to the suppression of the nonspecific host defense mechanisms also.

AB - There was executed the examination of patients with occupational chronic mercury intoxication in the post-exposure period after the exposure to metallic mercury vapor. 47 persons with an established diagnosis of chronic mercury intoxication (HMI) passed the laboratory and immunological examination in the period of exposure to metallic mercury vapor in a production environment. The average age of men accounted for 49.2+/-1.2 years. The experience of work in hazardous working conditions amounted of 21.65+/-1.61 years (1 observation). All these same cases were observed in the institute clinic again after 5 years (2 observation) and 10 years (3 observation). A control group of healthy men consisted of 47 cases included persons of representative both age and general work experience, without a professional route of contact with hazardous substances. The level of such cytokines as IL-1beta, IL-2, IL-4, IL-6, TNF-a, INF-y and neurotropic IgG class antibodies directed to proteins of the nervous tissue (NF-200, GFAP, MBP, B dependent Ca-channel, Glu-R, DA-R, R-GABA, Ser-R, R-Chol, DNA, B2GP) in serum were determined by enzyme linked immunosorbent assay. There was established the gain in the imbalance of inflammatory mediators and production ofneural antibodies in dynamics after the termination of the production in conditions of metallic mercury vapors. Revealed features of the regulatory relationship between the level of cytokines and the severity of the autoimmune process were shown to contribute to the maintenance and progression of neurodegenerative processes. There was recommended the identification of immunoregulatory markers (IL-1beta, IL-4, TNF-a, NF-AT to 200, GFAP, S-100) as an additional criteria for the diagnosis of health disorders in operating and monitoring the course of the progredient professional mercury intoxication.

AB - There are many harmful factors that possess a damaging impact on the body of employees at aluminum production. It leads to the development of bronchial asthma (BA), chronic nonobstructive bronchitis (CNB) and chronic obstructive pulmonary disease (COPD). The pathogenesis of these disorders, as well as sensitizing effect offluorine in the aluminum production is not fully understood. The purpose of this work was to study the characteristics of laboratory indices in patients with occupational diseases of the respiratory system. In workers of aluminum production with the diagnosis of occupational diseases of respiratory system (15 patients with a diagnosis of asthma, 30 CNB cases, 20 COPD patients) we evaluated the content of total protein, total cholesterol, high density lipoprotein cholesterol (HDLC), total calcium, phosphorus, ceruloplasmin, hematological indices and performed emigration of leukocytes braking test (TTEEL). Clinical and biochemical profile ofpersons with occupational asthma was characterized by a low level of total calcium and ceruloplasmin, a high concentration of phosphorus in the blood serum and inhibition of leukocyte emigration in the test with sodium fluoride. For aluminum production CNB workers characteristic active proatherogenic process was pronounced by a decrease in the HDLC level and an increase in atherogenic index; higher hematocrit value and concentration of erythrocytes, and more than 50% of cases of sensitization to the presence of sodium fluoride. COPD cases had occupational lower average concentration of hemoglobin in the erythrocyte, total protein in serum, as well as polymorphic variant response to sodium fluoride in the form of a depression and activation of leucocytes emigration.

AB - Tunnels are an integral part of the ways and artificial constructions of the railway. Objective assessment of working conditions is important, because current regulations fail to allow to give a definite hygienic assessment of some factors of the production environment of the tunnels. Objective: to reveal the peculiarities of the formation of working conditions in railway tunnels with the subsequent hygienic assessment for the development of preventive measures. Measurement of the factors of working process and working environment is carried out with the use of the certified equipment for the approved the hygienic and sanitary-chemical methods in workplaces in tunnels of the East-Siberian railway. Specific conditions were shown to be formed due to constructive solutions, climate and geographical location, the length of railway tunnels, the composition of the rocks through which the tunnel, the nature of the maintenance tunnels, ventilation system, repetition rate and type of passing rolling stock. All employees from occupational groups from examined tunnels were established to be exposed to high concentrations of aerosols with predominantly fibrogenic action, noise levels, adverse climate (low positive and negative temperatures, high relative humidity and mobility of air), the lack of natural lighting, low levels of artificial light, hard exertion of labor (dynamic physical load, working position, the slopes of the body, movement in space). Additionally, high levels of the vibration, nonionizing and ionizing radiation were typical for jobs of the Baikal and the North-Muya tunnel. There is proposed the algorithm of hygienic assessment of the microclimate, light environment at the working places depending on the time of the works in the underground conditions and constructional features of tunnels, methods of accounting personnel dose rates from natural sources.

AB - The rail transport is the one of the leading sectors of the national economy. More than 50% of the employees of the enterprises of the railway complex work under the unfavourable impact of hazardous and dangerous substances and occupational factors. In the literature issues of working conditions and health of employees of railway carrepairing plant are hardly highlighted. The aim of the study is the evaluation of the morbidity rate shaped under the influence of harmful occupational factors for the elaboration of preventive measures. In the work there were used generally accepted methods of hygienic studies, analysis of morbidity rate with temporary disability (TD), according to records of periodic medical examinations, occupational prevalence. The railway car-repairing plant was established to be characterized by the complex of harmful factors of the working environment and labor process: noise, local vibration, industrial aerosols of complex composition, chemicals, low light, hardness of the labor process. The levels of incidence with temporal disability in the studied groups, depending on the work seniority in the harmful labor conditions, significantly decrease with the experience from 5 to 9 years and increase with the experience more than 10 years. Executed in-depth analysis as of the both morbidity rate and TD, as well results of periodic medical examinations of workers of main shops shows that overall indices of the morbidity rate and TD are significantly higher than in the comparison group; levels of the morbidity rate and TD in the observed groups significantly decline depending on the length of service in hazardous working conditions with a length of the experience offrom 5 to 9 years and increase with the increase in the length of experience of 10 years or more. In the structure of morbidity and TD leading positions are occupied by diseases of the respiratory system, musculoskeletal system and connective tissue, circulatory system and digestive system, diseases of the eye and its appendages. The health damage risk coefficients in the studied groups of workers and the average losses of working time due to the morbidity with TD per 1 employee in all shops are higher than those in the comparison group. The level of the occupational morbidity rate is very low. Harmful working conditions contribute to the development of general and occupationally related diseases.

AB - It was found that the appearance of respiratory diseases among workers was established to be associated with the impact of aerosols with the complex chemical composition, exceeding corresponding MAC. Among respiratory diseases in workers there were detected predominantly chronic non-obstructive bronchitis - 59.15%, and chronic obstructive pulmonary disease (COPD) - in 35.2% of cases. In the analysis of spirometric indices of examined patients the vast majority (76.3%) of them showed disturbances of the bronchial patency of mild to moderate degree of the pronouncement. As a result of the implementation offlexible bronchoscopy there was established the presence of a diffuse lesion of bronchi with a predominance of subatrophic and atrophic processes in the mucosa. It was found that under the increase of the concentration of HF in the air of industrial premises the probability of bronchial obstruction and deterioration of the tracheobronchial patency in aluminum smelter workers was established to elevate.

AB - The purpose of research is the assessment of the individual cancer risk (ICR) for workers of the basic occupations in key branches of industry of the Irkutsk region. There was executed the calculation of ICR levels for workers of the basic occupations of the aircraft industry, aluminum smelters and vinyl chloride production plants. The estimation of the exposure for workers was carried out according to long-term time-weighted average concentrations in the air of the working area, for the population - on annual average concentrations in the ambient air. To assess the risk that is not associated with the profession, the dose was calculated for the period of life (70 years). When calculating the toxicant doses in the working area there were used the "standard" indices ofpulmonary ventilation for adults, body weight, the work experience in the contact with carcinogens of 30 years, the number of days in the contact of 240, the duration of the working time 8 or 12 hours (in accordance with the working hours) duration. ICR for the Irkutsk population amounted of 3.08E-04, in Shelekhov - 4.8E-05, Sayansk - 1.1E-05. The amount of risk depends on the content offormaldehyde in all territories and chromium VI in cities of Irkutsk and Shelekhov. ICR for workers of basic occupations of studied plants in dozens of times are higher than for the urban population. Priority carcinogens are: chromium VI, nickel, formaldehyde, silicon dioxide -for the aircraft plant employees; 1,2-dichloretan, vinyl chloride - for the workers of vinyl chloride production plant; benzopyrene - for the aluminum smelter workers.

AB - Results of the clinical and neurophysiological examinations of 42 workers with operating history at the chemical plant exposed to vinyl chloride (VC) are presented. The purpose of research was the identification ofpeculiarities of clinical manifestations and disorders of the functional activity of the brain in workers at the vinyl chloride production, with taking into account the exposure toxic load (ETL). There were made clinical and electroencephalographic examinations with the detection of cognitive evoked potentials (CEP) and statistical analysis of results with the use of the Mann-Whitney U-test, Fisher's F-test, calculation of Spearman's correlation coefficient. The features in clinical picture of the pathology of the nervous system were detected in the form of asthenic disorders with cognitive impairment and autonomic dysfunction syndrome. There was established the increase in the cognitive impairment rate (p = 0.03), the decline in a-EEG activity (p = 0.01) and the worsening of indices of the amplitude (p = 0.011) and latency (p = 0,05) of CEP in extremely high level of ETL in comparison with same indices in the group with moderately high ETL. In the first group there was revealed a statistically significant exceedance of the frequency of hypertension - by 1.6 times, skin diseases - by 9 times, chronic subatrophic rhino-pharyngitis by 1.4 times in comparison with cases from the second group. In the group with moderately high level of ETL there was established the statistically significant inverse correlationship between the ETL and the index of P300 amplitude from the left side (r = -0.38, p = 0.019) and in the group with extremely high level ETL - between ETL and index of the beta2 - rhythm (r = - 0.73, p = 0.0008).

PMID- 29446300 TI - Mineralogical Evidence of Galvanic Corrosion in Drinking Water Lead Pipe Joints. AB - Galvanic corrosion as a mechanism of toxic lead release into drinking water has been under scientific debate in the U.S. for over 30 years. Visual and mineralogical analysis of 28 lead pipe joints, excavated after 60+ years from eight U.S. water utilities, provided the first direct view of three distinct galvanic corrosion patterns in practice: (1) no evidence of galvanic corrosion; (2) galvanic corrosion with lead cathode; (3) galvanic corrosion with lead anode. Pattern 3 is consistent with empirical galvanic series (lead -> brass -> copper in order of increasing nobility) and poses the greatest risk of Pb exposure. Pattern 2 is consistent with galvanic battery reversion. The identification of copper-sulfate minerals (Pattern 2), and lead-sulfate and lead-chloride minerals (Pattern 3) in galvanic zones illustrated the migration of chloride and sulfate toward the anode. Geochemical modeling confirmed the required pH drop from the bulk water level to at least pH 3.0-4.0 (Pattern 2) and pH < 5.5 (Pattern 3) in order to form these minerals. Despite joints being over 60 years old, galvanic zones in Pattern 3 were active and possibly posed an important source of lead to drinking water. Importantly, Pattern 3 was not observed in samples from systems representing water qualities favoring PbO2 formation. PMID- 29446301 TI - Plasmon Waveguiding in Nanowires. AB - Nanowires supporting propagating surface plasmons can function as nanowaveguides to realize the light guiding with field confinement beyond the diffraction limit, providing fundamental building blocks for nanophotonic integrated circuits. This review covers the recent developments of plasmon waveguiding in nanowires, mainly including plasmon waveguiding in metal nanowires, coupling of nanowire plasmons and emitters, hybrid nanowire waveguides and plasmonic gain, and nanowire photonic devices. We first introduce the main techniques for fabricating metal nanowires, the plasmon modes in metal nanowires and the excitation/detection methods. We then discuss the fundamental properties of plasmon propagation and emission, including zigzag, chiral and spin-dependent propagation, mode conversion, loss and propagation length, group velocity, terminal emission, and leaky radiation. Then the interactions between nanowires and emitters are reviewed, especially the coupling of single nanowires and single quantum emitters. Finally, we briefly introduce the hybrid nanowire waveguide composed of a semiconductor nanowire and a metal film with an intervening thin insulator and highlight a few nanophotonic devices based on plasmonic nanowire networks or plasmonic-photonic hybrid nanowire structures. PMID- 29446302 TI - Life Cycle Assessment of Connected and Automated Vehicles: Sensing and Computing Subsystem and Vehicle Level Effects. AB - Although recent studies of connected and automated vehicles (CAVs) have begun to explore the potential energy and greenhouse gas (GHG) emission impacts from an operational perspective, little is known about how the full life cycle of the vehicle will be impacted. We report the results of a life cycle assessment (LCA) of Level 4 CAV sensing and computing subsystems integrated into internal combustion engine vehicle (ICEV) and battery electric vehicle (BEV) platforms. The results indicate that CAV subsystems could increase vehicle primary energy use and GHG emissions by 3-20% due to increases in power consumption, weight, drag, and data transmission. However, when potential operational effects of CAVs are included (e.g., eco-driving, platooning, and intersection connectivity), the net result is up to a 9% reduction in energy and GHG emissions in the base case. Overall, this study highlights opportunities where CAVs can improve net energy and environmental performance.

AB - INTRODUCTION: The aim of this paper is to ascertain the number of patients with pre-injury warfarin use who developed lower extremity hematomas treated in our facility, to analyse the data, used treatment methods and outcomes in these patients. PATIENTS AND METHODS: We performed a retrospective review, identifying all the patients with pre-injury Warfarin use admitted with hematoma or full thickness skin loss in the ten years period from January 2006 to December 2015. RESULTS: Overall 9 women and 2 men with mean age of 72 years were identified. All the injuries were sustained in a domestic setting. Except of one female patient primarily admitted to our department, all patients had been hospitalized primarily in local/regional hospitals for an average period of 32.6 days. All the patients transferred to our department required surgical wound closure. The mean wound surface area was 136.3cm2 (range 45-525). The duration of hospital stay was 15 days in average. DISCUSSION: The data obtained were compared with the results and findings of similar studies and were discussed. CONCLUSION: The results achieved in the present study showed the beneficial effect of used treatment methods based on the surgical wound closure techniques during hospital stay of the patients. Clinicians, first contact physicians, and also patients alone need to be aware of the vulnerability of this group of patients. The consequences of even minor lower extremity trauma can be serious, with development of a very complex chronic wound that is difficult to manage. PMID- 29446304 TI - SURGICAL CORRECTION OF LABIA MINORA HYPERTROPHY, A PERSONAL TECHNIQUE. AB - BACKGROUND: Labia minora hypertrophy is a congenital or acquired condition in which both labia minora (or more rarely only one) protrude beyond the edge of the labia majora. The authors present a surgical technique of volumetric reduction of hypertrophic labia minora, associated with lipofilling of the labia majora. METHODS: Between 2005 and 2014, 27 patients underwent surgical reduction of labia minora, as described by Altier and Rouzier. The indications for surgical treatment varied and were as follows: interference with sexual intercourse; poor hygiene; difficulty wearing tight-fitting pants; difficulty while performing sporting activities such as cycling; aesthetic complaints. The surgical resection was associated with fat graft injection in labia majora in order to protect and cover the labia minora. The mean follow up was 1 year. RESULTS: The labia majora, increased in volume and firmness, cover and protect the labia minora slightly hypertrophic or surgically reduced. All patients reported an improvement in comfort, aesthetic appearance, when wearing close-fitting clothes and an improvement in their sexuality. In one case we recorded a "recurrence", with an increase of dimensions in width of labia minora, still lower than the preoperative situation but greater than the immediate postop. CONCLUSIONS: The reduction of labia minora hypertrophy with conservative techniques allows achieving excellent results in terms of aesthetics and functionality. The simple lipofilling of labia majora allows preserving and protecting the labia minora through a volumetric increase of the labia majora. PMID- 29446305 TI - SUTURE VERSUS FIBRIN GLUE MICRONEURAL ANASTOMOSIS OF THE FEMORAL NERVE IN SPRAGUE DEWLY RAT MODEL. A COMPARATIVE EXPERIMENTAL ASSESSMENT OF THE CLINICAL, HISTOLOGICAL AND STATISTICAL FEATURES. AB - INTRODUCTION: Peripheral nerve injury is a frequently encountered clinical problem that leads to functional losses at the long-term. Although microsurgical repair has been introduced to clinical practice in peripheral nerve injuries, unsatisfactory outcomes regarding functional recovery in target organ cause an increasing interest on studies about nerve injury and biology of the recovery in nerve injuries1. MATERIAL AND METHODS: Sciatic nerves of seventy adult Sprague Dewly rats were transected and primary anastomosis was performed. Rats were then divided into three groups: Control group, while 30 rats were repaired with sutures, and the remaining 30 were repaired with fibrin glue. After 30 days the rats were sacrified and the sciatic nerves were investigated histologically with morphometrical and statistical analyses. RESULTS: In microsurgical nerve repair, suture placement has been thought to cause hindrance to the sprouting axons and compress the blood supply to the fascicles, thereby impairing the regeneration of the transected nerve ends after repair, with possible neuroma formation. On the other hand, fibrin glue is a simple, effective technique, less time consuming than suturing. Another advantage of this suture-free technique is that it avoids injuring the axon with needles, and the lack of foreign bodies minimizes the inflammatory reaction. CONCLUSION: We recommend using fibrin glue as it demonstrates less inflammatory reaction, less scar tissue formation, it is less time consuming and provides better outcomes. PMID- 29446306 TI - INTRAOPERATIVE FAT GRAFTING INTO THE PECTORALIS AND LATISSIMUS DORSI MUSCLES NOVEL MODIFICATION OF AUTOLOGOUS BREAST RECONSTRUCTION WITH EXTENDED LATISSIMUS DORSI FLAP. AB - BACKGROUND: The latissimus dorsi flap is a reliable and one of the most commonly used methods of both immediate and delayed breast reconstruction. Its disadvantage is the limited volume of transferred tissue. The authors present their experience with the use of extended latissimus dorsi flap associated with immediate fat grafting into the pectoralis and latissimus dorsi muscles for secondary breast reconstruction. METHODS: From 2013 to 2016, 14 patients underwent secondary unilateral total breast reconstruction with extended latissimus dorsi flap associated with primary fat grafting into the pectoralis major and latissimus dorsi muscles. Fat was injected under visual control between muscle fibers. Fat injected into the pectoralis muscle formed an apparent bulging - autoprosthesis. RESULTS: Mean patient age was 48.2 years (range, 34 to 64 years). Mean injected fat volume was 86.4 ml (range, 50 to 160 ml) and majority of this volume was injected into the pectoralis muscle. All flaps healed uneventfully and no fat grafting-related complications were observed. The most common complication was donor site seroma, which occurred in 57.1%. Results of postoperative ultrasound examination were evaluated. Incidence and the size of oil cysts and fat necroses were significantly lower in muscular layer in comparison with the subcutaneous layer of the reconstructed breast. CONCLUSIONS: Immediate fat transfer into the pectoralis and latissimus dorsi muscle increases the breast volume during the reconstruction with extended latissimus dorsi flap avoiding implant-related complications when abdominal tissue is not available. Pectoralis and latissimus dorsi muscles were shown as reliable and safe recipients for fat grafting. PMID- 29446307 TI - HAS A GLOMUS TUMOR ALWAYS A QUICK DIAGNOSIS? AB - INTRODUCTION: Glomus tumor is a rare and benign vascular tumor. Although symptoms specific for this tumor are quite clear, there is still a delay between the onset of symptoms, diagnosis and subsequent surgical therapy. The authors monitor the time from the onset of symptoms to the diagnosis and management of the problems. MATERIAL AND METHODS: Between 2004-2012, a total of 5 patients were diagnosed with subungual glomus tumor in the area of the distal phalanges of the hand. It involved 3 women and 2 men with the mean age of 32.2 years (26-47 years). During the first examination, we monitored the duration of symptoms, number and specialty of the doctors who examined the patient, and what examinations were performed. When the cold test was positive, MRI was performed and the patients were indicated for surgical revision. Tissue samples in all patients were histologically examined. Patients were followed for 2 years. RESULTS: It was found that the patients had clinical symptoms for an average of 2.4 years. In our group, the patients were examined by an average of 5.4 physicians (3-9 physicians). On examination before surgery, three patients reported changes in the nail bed and two patients reported no change. When following the patients 2 years after the surgery, relapse occurred in one patient and it was treated with reoperation. During regular follow-up 2 years after the surgery, 4 patients were without nail deformity. In one patient, there was resulting nail deformity. Relapse occurred in only one case. DISCUSSION: Because the glomus tumor is a rare lesion, occurring most frequently in the nail bed, early diagnosis is still a problem. Even in literature, we encounter a similar time frame from the onset of symptoms until the final diagnosis of 1.9 to 8 years. CONCLUSION: Although clinical signs and problems concerning the glomus tumor are very obvious, there still remains a long time for diagnosis. It would certainly be most beneficial for patients with persistent symptoms not to be referred to different specialists, but directly to a department that specializes in hand surgery. PMID- 29446308 TI - CURRENT CONCEPTS IN PERIPHERAL NERVE INJURY REPAIR. AB - Even though reconstructive surgery of the nerves underwent significant progress due to experimental and clinical research over the past 40 years, injuries to the peripheral nerves still remain a great challenge for microsurgery. Literature results of these procedures are often evaluated as very good but the final result is often characterized by an achievement of only a useful and not full function, which is rather rare. It is not only a simple suture; the success is also based on functional regeneration and interconnection of the nerve fibres. This is limited by correct surgical technique, the age of the patient, delay from the time of injury and the mechanism or localization of the injury. Some injuries even now remain untreatable (such as the most severe brachial plexus injuries or long traction injuries of the peroneal nerve). Apart from standard neurolysis and epi- or perineural suture with or without nerve grafts, distal nerve transfers (in case of proximal injuries) and end-to-side neurorrhaphy (mainly in trauma of sensitive nerves) have recently been frequently used. The future is however based on influence of nerve regeneration at the cellular level using substances with growth potential. The main prerequisite of successful surgery is however early indication of surgical revision in a specialized centre. PMID- 29446309 TI - SUBACUTE ARTERIAL BLEEDING AFTER SIMULTANEOUS MASTOPEXY AND BREAST AUGMENTATION WITH IMPLANTS: CASE REPORT. AB - Breast augmentation with implants is one of the most commonly performed plastic surgery procedures. The goal of the operation is to increase the size, shape or fullness of the breast. It is accomplished by placing silicone, saline or alternative composite breast implants under the chest muscles, fascia or the mammary gland. This type of operation is no exception with regards to concerning the occurrence of complications. The most common early complications include an infectious process, a seroma, and a hematoma, and the late ones include capsular contracture, reoperation, implant removal, breast asymmetry, and a rupture or deflation of the implant. The authors present a case of subacute arterial bleeding after simultaneous mastopexy and breast augmentation with silicone implants in a 27-year-old woman. The patient complained of worsening swelling and pain in the right breast. The patient denied having had any traumas. Ultrasonography indicated 2.5 cm heterogeneous fluid collections around the implant. Therefore, revision surgery was performed, and a hematoma of 650 mL was removed. Hemorrhage from a branch of the internal mammary artery was found. After the revision, the implant was returned to the lodge. The postoperative period was uneventful. This case report presents a description of a subacute hematoma after simultaneous mastopexy and breast augmentation with silicone implants, which is an extremely rare complication in aesthetic surgery.

PMID- 29446312 TI - Interactive laboratory classes enhance neurophysiological knowledge in Thai medical students. AB - Interactive laboratory class (ILC) is a two-way communication teaching method that encourages students to correlate laboratory findings with materials from lectures. In Thai medical education, active learning methods are uncommon. This paper aims to establish 1) if ILCs would effectively promote physiology learning; 2) if effectiveness would be found in both previously academically high performing and low-performing students; and 3) the acceptability of ILCs to Thai medical students as a novel learning method. Two hundred seventy-eight second year medical students were recruited to this study. We conducted three ILC sessions, which followed corresponding lectures. We carried out multiple-choice pre- and post-ILC assessments of knowledge and compared by repeated-measures ANOVA and unpaired t-test. Subgroup analysis was performed to compare high performance (HighP) and low-performance (LowP) students. After the ILCs, participants self-rated their knowledge and satisfaction. Post-ILC test scores increased significantly compared with pre-ILC test scores in all three sessions. Mean scores of each post-ILC test increased significantly from pre-ILC test in both LowP and HighP groups. More students self-reported a "very high" and "high" level of knowledge after ILCs. Most students agreed that ILCs provided more discussion opportunity, motivated their learning, and made lessons more enjoyable. As an adjunct to lectures, ILCs can enhance knowledge in medical students, regardless of previous academic performance. Students perceived ILC as useful and acceptable. This study supports the active learning methods in physiology education, regardless of cultural context. PMID- 29446313 TI - Digital chalk-talk videos improve knowledge and satisfaction in renal physiology. AB - The authors began a curriculum reform project to improve the experience in a Renal Physiology course for first-year medical students. Taking into account both the variety of learning preferences among students and the benefits of student autonomy, the authors hypothesized that adding digital chalk-talk videos to lecture notes and live lectures would improve student knowledge, course satisfaction, and engagement. The authors measured performance on the renal physiology exam before (the traditional curriculum) and for 2 yr after implementation of the new curriculum. During the traditional and subsequent years, students took a Q-sort survey before and after the Renal Physiology course. Satisfaction was assessed based on ranked statements in the Q sort, as well as through qualitative analysis of student commentary. Compared with the traditional curriculum, mean scores on the renal physiology final exam were higher after implementation of the new curriculum: 65.3 vs. 74.4 ( P < 0.001) with year 1 and 65.3 vs. 79.4 ( P < 0.001) in the second year. After the new curriculum, students were more likely to agree with the statement, "I wish other courses were taught like this one." Qualitative analysis revealed how the video based curriculum improved student engagement and satisfaction. Adding digital chalk-talk videos to a traditional Renal Physiology course that included active learning led to improved exam performance and high levels of student satisfaction. Other preclinical courses in medical school may benefit from such an intervention.

PMID- 29446315 TI - Left ventricular volume analysis as a basic tool to describe cardiac function. AB - The heart is often regarded as a compression pump. Therefore, determination of pressure and volume is essential for cardiac function analysis. Traditionally, ventricular performance was described in terms of the Starling curve, i.e., output related to input. This view is based on two variables (namely, stroke volume and end-diastolic volume), often studied in the isolated (i.e., denervated) heart, and has dominated the interpretation of cardiac mechanics over the last century. The ratio of the prevailing coordinates within that paradigm is termed ejection fraction (EF), which is the popular metric routinely used in the clinic. Here we present an insightful alternative approach while describing volume regulation by relating end-systolic volume (ESV) to end-diastolic volume. This route obviates the undesired use of metrics derived from differences or ratios, as employed in previous models. We illustrate basic principles concerning ventricular volume regulation by data obtained from intact animal experiments and collected in healthy humans. Special attention is given to sex-specific differences. The method can be applied to the dynamics of a single heart and to an ensemble of individuals. Group analysis allows for stratification regarding sex, age, medication, and additional clinically relevant covariates. A straightforward procedure derives the relationship between EF and ESV and describes myocardial oxygen consumption in terms of ESV. This representation enhances insight and reduces the impact of the metric EF, in favor of the end systolic elastance concept advanced 4 decades ago. PMID- 29446316 TI - Impact of the INBRE summer student mentored research program on undergraduate students in Arkansas. AB - The Institutional Development Award (IDeA) program, housed within the National Institute for General Medical Sciences, administers the Networks of Biomedical Research Excellence (INBRE) as a strategic mission to broaden the geographic distribution of National Institutes of Health (NIH) funding within the United States. Undergraduate summer student mentored research programs (SSMRP) are a common feature of INBRE programs and are designed to increase undergraduate student interest in research careers in the biomedical sciences. Little information is available about student perspectives on how these programs impact their choices relative to education and careers. Therefore, we conducted qualitative interviews with 20 participants from the Arkansas INBRE SSMRP in the years 2002-2012. Each telephone interview lasted 30-45 min. An interview guide with a broad "grand tour" question was used to elicit student perspectives on SSMRP participation. Interviews were digitally recorded, then transcribed verbatim, and the transcript checked for accuracy. Content analysis and constant comparison were used to identify nine themes that were grouped into three temporal categories: before, during, and after the SSMRP experience. Students viewed the experience as positive and felt it impacted their career choices. They emphasized the value of mentoring in the program, and some reported maintaining a relationship with the mentor after the summer experience ended. Students also valued learning new laboratory and presentation skills and felt their research experience was enhanced by meeting students and scientists with a wide range of career interests. These data suggest that the Arkansas INBRE and the NIH IDeA program are successfully meeting the goal of increasing interest in research among undergraduates.

It is the role of the occupational health nurse practitioner to evaluate and reduce the risk of cardiovascular disease in this population. PMID- 29446317 TI - Credentialing of radiotherapy centres in Australasia for TROG 09.02 (Chisel), a Phase III clinical trial on stereotactic ablative body radiotherapy of early stage lung cancer. AB - OBJECTIVE: A randomised clinical trial comparing stereotactic ablative body radiotherapy (SABR) with conventional radiotherapy for early stage lung cancer has been conducted in Australia and New Zealand under the auspices of the TransTasman Radiation Oncology Group (NCT01014130). We report on the technical credentialing program as prerequisite for centres joining the trial. METHODS: Participating centres were asked to develop treatment plans for two test cases to assess their ability to create plans according to protocol. Dose delivery in the presence of inhomogeneity and motion was assessed during a site visit using a phantom with moving inserts. RESULTS: Site visits for the trial were conducted in 16 Australian and 3 New Zealand radiotherapy facilities. The tests with low density inhomogeneities confirmed shortcomings of the AAA algorithm for dose calculation. Dose was assessed for a typical treatment delivery including at least one non-coplanar beam in a stationary and moving phantom. This end-to-end test confirmed that all participating centres were able to deliver stereotactic ablative body radiotherapy with the required accuracy while the planning study demonstrated that they were able to produce acceptable plans for both test cases. CONCLUSION: The credentialing process documented that participating centres were able to deliver dose as required in the trial protocol. It also gave an opportunity to provide education about the trial and discuss technical issues such as four-dimensional CT, small field dosimetry and patient immobilisation with staff in participating centres. Advances in knowledge: Credentialing is an important quality assurance tool for radiotherapy trials using advanced technology. In addition to confirming technical competence, it provides an opportunity for education and discussion about the trial. PMID- 29446319 TI - Dual-energy CT iodine maps as an alternative quantitative imaging biomarker to abdominal CT perfusion: determination of appropriate trigger delays for acquisition using bolus tracking. AB - OBJECTIVE: Quantitative evaluation of different bolus tracking trigger delays for acquisition of dual energy (DE) CT iodine maps as an alternative to CT perfusion. METHODS: Prior to this retrospective analysis of prospectively acquired data, DECT perfusion sequences were dynamically acquired in 22 patients with pancreatic carcinoma using dual source CT at 80/140 kVp with tin filtration. After deformable motion-correction, perfusion maps of blood flow (BF) were calculated from 80 kVp image series of DECT, and iodine maps were calculated for each of the 34 DECT acquisitions per patient. BF and iodine concentrations were measured in healthy pancreatic tissue and carcinoma. To evaluate potential DECT acquisition triggered by bolus tracking, measured iodine concentrations from the 34 DECT acquisitions per patient corresponding to different trigger delays were assessed for correlation to BF and intergroup differences between tissue types depending on acquisition time. RESULTS: Average BF measured in healthy pancreatic tissue and carcinoma was 87.6 +/- 28.4 and 38.6 +/- 22.2 ml/100 ml min-1, respectively. Correlation between iodine concentrations and BF was statistically significant for bolus tracking with trigger delay greater than 0 s (rmax = 0.89; p < 0.05). Differences in iodine concentrations between healthy pancreatic tissue and carcinoma were statistically significant for DECT acquisitions corresponding to trigger delays of 15-21 s (p < 0.05). CONCLUSION: An acquisition window between 15 and 21 s after exceeding bolus tracking threshold shows promising results for acquisition of DECT iodine maps as an alternative to CT perfusion measurements of BF. Advances in knowledge: After clinical validation, DECT iodine maps of pancreas acquired using bolus tracking with appropriate trigger delay as determined in this study could offer an alternative quantitative imaging biomarker providing functional information for tumor assessment at reduced patient radiation exposure compared to CT perfusion measurements of BF. PMID- 29446320 TI - Inhibition of mucin secretion via glucocorticoid-induced regulation of calcium related proteins in mouse lung. AB - Calcium is important for physiological functioning in many tissues and is essential in mucus secretion and muscle contraction. Intracellular concentrations of calcium are regulated by calcium-related proteins, such as transient receptor potential cation channel subfamily V member 4 (TRPV 4), TRPV6, Calbindin-D9k (CaBP-9k), sodium-calcium exchanger (NCX1), and plasma membrane Ca2+ ATPase 1 (PMCA1). In this study, the relationship between secretion of pulmonary mucus and calcium regulation was investigated. To confirm the effect of steroid hormones, immature mice were injected with estrogen (E2) or progesterone (P4), and mature mice were injected with dexamethasone (DEX). Subsequently, the location and expression of TRPV4, TRPV6, CaBP-9k, NCX1, and PMCA1 in lung tissue were examined. Periodic acid-Schiff staining was performed to investigate functional aspects of the protein expression. There were no significant differences in calcium-related gene expression in E2- and P4-treated mice, but TRPV4, NCX1, and PMCA1 were increased in DEX-treated mice and were recovered by RU486 treatment. DEX induces the expression of calcium-related proteins through the glucocorticoid receptor-mediated pathway and may involve decreased mucin secretion in the bronchiole. TRPV4, TRPV6, CaBP-9k, NCX1, and PMCA1 were specifically expressed in Clara and alveolar type 2 cells of mouse lung. CC10, a marker of Clara cells, was decreased by DEX. In addition, mucin secretion, which is a functional aspect of this cell, was also decreased by DEX treatment. Control of calcium-related gene expression may affect the control of mucus secretion in the lung. Such a control mechanism can form the basis of studies into diseases such as inflammation attributable to mucus secretion abnormalities, coughing, and respiratory disorders and distress. PMID- 29446321 TI - Pulmonary IL-1beta expression in early life causes permanent changes in lung structure and function in adulthood. AB - Chorioamnionitis, mechanical ventilation, oxygen therapy, and postnatal infection promote inflammation in the newborn lung. The long-term consequences of pulmonary inflammation during infancy have not been well characterized. The aim of this study was to examine the impact of inflammation during the late saccular to alveolar stages of lung development on lung structure and function in adulthood. To induce IL-1beta expression in the pulmonary epithelium of mice with a tetracycline-inducible human IL-1beta transgene, doxycycline was administered via intraperitoneal injections to bitransgenic pups and their littermate controls on postnatal days (PN) 0, 0.5, and 1. Lung structure, inflammation, and airway reactivity were studied in adulthood. IL-1beta production in early life resulted in increased numbers of macrophages and neutrophils on PN21, but inflammation subsided by PN42. Permanent changes in alveolar structure, i.e., larger alveoli and thicker alveolar walls, were present from PN21 to PN84. Lack of alveolar septation thus persisted after IL-1beta production and inflammation had ceased. Early IL-1beta production caused goblet cell hyperplasia, enhanced calcium activated chloride channel 3 (CLCA3) protein expression, and increased airway reactivity in response to methacholine on PN42. Lymphoid follicles were present adjacent to small airways in the lungs of adult bitransgenic mice, and levels of the B cell chemoattractant CXC-motif ligand (CXCL) 13 were elevated in the lungs of bitransgenic mice compared with controls. In conclusion, IL-1beta-induced pulmonary inflammation in early life causes a chronic lung disease in adulthood. PMID- 29446323 TI - Conners 3-Self-Report Scale: An empirical support to the dimensionality of the content scales. AB - The Conners' Rating Scales are one of the most used instruments for attention deficit/hyperactivity disorder (ADHD). Nonetheless, in the latest edition, the Inattention scale was not statistically supported. This study examined the dimensionality of the Italian version of the Conners 3-Self-Report scale testing both a five-factor structure including Inattention and a four-factor model combining Inattention and Learning Problems. Moreover, the generalizability of the detected structure through measurement invariance was verified. The Italian version of the scale was completed by 971 children (53% males, mean age: 12.76 years) randomly split in a calibration sample ( n = 464) and a validation sample ( n = 507). Confirmatory factor analyses detected a five-factor structure (i.e. Inattention, Hyperactivity/Impulsivity, Learning Problems, Defiance/Aggression, and Family Relations), and measurement invariance was confirmed. Findings provided statistical evidence for the Inattention subscale, supporting the Conners 3-Self-Report Scale as effectively aimed to assess the two dimensions of ADHD and its main comorbid difficulties. PMID- 29446322 TI - BOLD MRI to evaluate early development of renal injury in a rat model of diabetes. AB - Objective To investigate changes in renal oxygenation levels by blood-oxygenation level dependent (BOLD)-magnetic resonance imaging (MRI), and to evaluate BOLD-MRI for detecting early diabetic renal injury. Methods Seventy-five rats, with unilateral nephrectomy, were randomly divided into streptozotocin-induced diabetes mellitus (DM, n = 65) and normal control (NC, n = 10) groups. BOLD-MRI scans were performed at baseline (both groups) and at 3, 7, 14, 21, 28, 35, 42, 49, 56, 63 and 70 days (DM only). Renal cortical (C) and medullary (M) R2* signals were measured and R2* medulla/cortex ratio (MCR) was calculated. Results DM-group CR2* and MR2* values were significantly higher than NC values following diabetes induction. R2* values increased gradually and peaked at day 35 (CR2*, 33.95 +/- 0.34 s-1; MR2*, 43.79 +/- 1.46 s-1), then dropped gradually (CR2*, 33.17 +/- 0.69 s-1; MR2*, 41.61 +/- 0.95 s-1 at day 70). DM-group MCR rose gradually from 1.12 to 1.32 at day 42, then decreased to 1.25 by day 70. Conclusions BOLD-MRI can be used to non-invasively evaluate renal hypoxia and early diabetic renal injury in diabetic rats. MCR may be adopted to reflect dynamic changes in renal hypoxia. PMID- 29446325 TI - Behaviour change techniques in physical activity interventions for men with prostate cancer: A systematic review. AB - Physical activity interventions can improve prostate cancer survivors' health. Determining the behaviour change techniques used in physical activity interventions can help elucidate the mechanisms by which an intervention successfully changes behaviour. The purpose of this systematic review was to identify and evaluate behaviour change techniques in physical activity interventions for prostate cancer survivors. A total of 7 databases were searched and 15 studies were retained. The studies included a mean 6.87 behaviour change techniques (range = 3-10), and similar behaviour change techniques were implemented in all studies. Consideration of how behaviour change techniques are implemented may help identify how behaviour change techniques enhance physical activity interventions for prostate cancer survivors. PMID- 29446324 TI - Hepatocellular carcinoma surveillance with ultrasound-cost-effectiveness, high risk populations, uptake. AB - Hepatocellular carcinoma (HCC) is the most frequent primary liver cancer and the second cause of cancer-related deaths worldwide. In most cases, it is diagnosed in patients with identified risk factors, mainly cirrhosis from all causes. These patients are candidates for a surveillance program that, depending on guidelines, involves regular liver ultrasound alone or combined with serum markers. These programs have been shown to improve the oncological outcome by detecting earlier stage tumors and providing patients with potentially curative treatment and improved survival. Yet, the level of evidence supporting these guidelines remains limited. This review article presents an overview of the evidence supporting surveillance programs for hepatocellular carcinoma, in particular the efficacy, cost-effectiveness, and consequences of this approach for patient survival. Western and Eastern guideline recommendations are described and discussed. PMID- 29446327 TI - Changes in Life Expectancy From 2006 to 2015 in Suzhou, East China: Contributions of Age- and Cause-Specific Mortality. AB - This study was designed to estimate the contribution of age- and disease-specific mortality, particularly that attributable to chronic noncommunicable diseases and at-birth life expectancy (LE) in Suzhou, East China, between 2006 and 2015. In total, data on 427 290 deaths were analyzed. From 2006 to 2015, the at-birth LE increased from 78.92 years to 82.87 years in Suzhou. A decrease in all-cause age specific death rates contributed to an increase of 1.98 years. The decreased death rates attributable to noncommunicable diseases including cerebrovascular diseases, cancer, heart disease, and respiratory diseases resulted in an increased LE of 1.37 years, which was particularly pronounced among people aged 65 years and older. However, the prevalence of cancer in those aged 45 to 74 years, particularly gastric, liver, and esophageal cancers, contributed the most to the increase in LE. These data may be useful for public health communications. PMID- 29446328 TI - Contribution of EEG signals to brain-machine interfaces.

PMID- 29446330 TI - Effectiveness in Regular Practice of Collaborative Care for Depression Among Adolescents: A Retrospective Cohort Study. AB - OBJECTIVE: Depression is common among adolescents, but many lack ready access to mental health services. Integrated models of care for depression are needed, along with evidence to support their use in regular practice. The authors examined the effectiveness of an ongoing collaborative care program for depressed adolescents embedded in a busy primary care practice. METHODS: This retrospective cohort study assessed EMERALD (Early Management and Evidence-based Recognition of Adolescents Living with Depression), a collaborative care program. All patients ages 12-17 and age 18 and still in high school with a score of >=10 on the nine item Patient Health Questionnaire for Adolescents (PHQ-9A) and without a diagnosis of bipolar disorder were eligible. The sample included 162 EMERALD participants and 499 similarly eligible non-EMERALD patients. Outcomes were six month remission of depression (score <5) and six-month treatment response (>50% reduction from baseline) as measured by the PHQ-9A. Analyses included logistic regression and propensity score matching to adjust for differences in demographic factors and number of contacts-observations. RESULTS: After propensity score matching, EMERALD patients had better adjusted rates of depression remission (11 percentage points higher, p=.035) and treatment response (14 percentage points higher, p<.001) than comparison patients. Results from primary analyses were as conservative as or more conservative than results from all sensitivity analyses tested. CONCLUSIONS: Collaborative care for adolescents in regular practice led to better remission and treatment response than usual care. Future studies could examine which groups might benefit most and flexible payment models to support these services. PMID- 29446331 TI - The Case for Severe Mental Illness as a Disparities Category. AB - Extensive evidence documents that people with severe mental illness have higher rates of morbidity and mortality compared with the general population and receive lower-quality and higher-cost health care. These trends, at least in part, stem from discrimination, exclusion, widespread stigma, and criminalization of individuals with mental illness. As such, severe mental illness should receive formal, national recognition as a disparities category. Such a designation would have multiple important implications in health policy, services and quality research, and advocacy. PMID- 29446333 TI - Delays in Seeking General Medical Services and Measurable Abnormalities Among Individuals With Serious Mental Illness. AB - OBJECTIVE: The study explored the association of delays in seeking general medical care with elevated blood pressure and metabolic abnormalities among individuals with serious mental illness. METHODS: Association of delays in medical care with blood pressure, serum hemoglobin A1c (HbA1C), and lipids was assessed among patients at two inner-city community mental health centers. RESULTS: Of 271 participants, 62% reported delays in seeking general medical care due to attitudinal and financial barriers. Care delay was associated with abnormalities in measured blood pressure (adjusted odds ratio [AOR]=2.14, p=.029) and HbA1c (AOR=3.18, p=.026). Care delay was not associated with abnormalities in lipid profiles. CONCLUSIONS: This study found that delays in seeking general medical care are common and are associated with clinical markers linked with common medical conditions. The results may help to explain the elevated morbidity and mortality associated with serious mental illness. PMID- 29446332 TI - General Medical, Mental Health, and Demographic Risk Factors Associated With Suicide by Firearm Compared With Other Means. AB - OBJECTIVE: Mitigation of suicide risk by reducing access to lethal means, such as firearms and potentially lethal medications, is a highly recommended practice. To better understand groups of patients at risk of suicide in medical settings, the authors compared demographic and clinical risk factors between patients who died by suicide by using firearms or other means with matched patients who did not die by suicide (control group). METHODS: In a case-control study in 2016 from eight health care systems within the Mental Health Research Network, 2,674 suicide cases from 2010-2013 were matched to a control group (N=267,400). The association between suicide by firearm or other means and medical record information on demographic characteristics, general medical disorders, and mental disorders was assessed. RESULTS: The odds of having a mental disorder were higher among cases of suicide involving a method other than a firearm. Fourteen general medical disorders were associated with statistically significant (p<.001) greater odds of suicide by firearm, including traumatic brain injury (TBI) (odds ratio [OR]=23.53), epilepsy (OR=3.17), psychogenic pain (OR=2.82), migraine (OR=2.35), and stroke (OR=2.20). Fifteen general medical disorders were associated with statistically significant (p<.001) greater odds of suicide by other means, with particularly high odds for TBI (OR=7.74), epilepsy (OR=3.28), HIV/AIDS (OR=6.03), and migraine (OR=3.17). CONCLUSIONS: Medical providers should consider targeting suicide risk screening for patients with any mental disorder, TBI, epilepsy, HIV, psychogenic pain, stroke, and migraine. When suicide risk is detected, counseling on reducing access to lethal means should include both firearms and other means for at-risk groups. PMID- 29446334 TI - Leveraging Behavioral Health Expertise: Practices and Potential of the Project ECHO Approach to Virtually Integrating Care in Underserved Areas. AB - This column describes Project ECHO (Extension for Community Healthcare Outcomes), a teleconsultation, tele-education, telementoring model for enhancing primary care treatment of underserved patients with complex medical conditions. Numerous centers have adapted ECHO to support primary care treatment of behavioral health disorders. Preliminary evidence for behavioral health ECHO programs suggests positive impacts on providers, treatment planning, and emergency department costs. ECHO has the potential to improve access to effective and cost-effective behavioral health care by virtually integrating behavioral health knowledge and support in sites where specialty providers are not available. Patient-level outcomes research is critical. PMID- 29446335 TI - Implementing Illness Management and Recovery Within Assertive Community Treatment: A Pilot Trial of Feasibility and Effectiveness. AB - OBJECTIVE: In a pilot feasibility and effectiveness study, illness management and recovery (IMR), a curriculum-based program to help people with serious mental illness pursue personal recovery goals, was integrated into assertive community treatment (ACT) to improve participants' recovery and functioning. METHODS: A small-scale cluster randomized controlled design was used to test implementation of IMR within ACT teams in two states. Eight high-fidelity ACT teams were assigned to provide IMR (ACT+IMR; four teams) or standard ACT services (ACT only; four teams). Clinical outcomes from 101 individuals with schizophrenia-spectrum or bipolar disorders were assessed at baseline, six months, and one year. RESULTS: Exposure to IMR (session attendance and module completion) varied between the ACT+IMR teams, with participants on one team having significantly less exposure. Results from intent-to-treat analyses showed that participants in ACT+IMR demonstrated significantly better outcomes with a medium effect size at follow-up on clinician-rated illness self-management. A nonsignificant, medium effect size was found for one measure of functioning, and small effect sizes were observed for client-rated illness self-management and community integration. Session and module completion predicted better outcomes on four of the 12-month outcome measures. CONCLUSIONS: Findings support the feasibility of implementing IMR within ACT teams. Although there were few significant findings, effect sizes on some variables in this small-scale study and the dose-response relationships within ACT+IMR teams suggest this novel approach could be promising for improving recovery for people with serious mental illness. Further large-scale studies utilizing a hybrid effectiveness-implementation design could provide a promising direction in this area.

Patients with psychiatric conditions are interested in mental health apps and have begun to use them. That does not mean that clinicians must support, endorse, or even adopt the use of apps, but they should be prepared to answer patients' questions about apps and facilitate shared decision making around app use. This column describes an evaluation framework designed by the American Psychiatric Association to guide informed decision making around the use of smartphone apps in clinical care. PMID- 29446339 TI - The rs1527483, but not rs3212018, CD36 polymorphism associates with linoleic acid detection and obesity in Czech young adults. AB - Recent evidence has raised the possibility of the existence of a sixth taste modality - that is, taste for fat - which is mediated by lingual CD36 and plays a role in obesity. Consequently, the genetic polymorphism of CD36 has been shown to be associated with altered oro-sensory detection of dietary lipids. In the present study, we investigated the relationship between oro-sensory perception of linoleic acid (LA), two CD36 polymorphisms (rs1527483 and rs3212018), obesity parameters and craving habits for dietary lipids in young Czech adults. We also sequenced 5 and 6 exons of CD36 to trace out any new mutation that might be responsible for the difference in taste perception. We observed that craving for dietary lipids was correlated with anthropometric parameters (P<0.05) and LA detection threshold (P=0.033). The participants with the CC genotype of the rs1527483 polymorphism had lower BMI (P=0.011), waist circumference (P=0.005), waist:height ratio (P=0.010) and higher sensitivity for LA (P=0.037) than the participants with the CT and TT genotypes. Interestingly, we did not observe any association between the rs3212018 polymorphism and the studied parameters. Moreover, we did not observe any mutation in exons 5 and 6 of the CD36 gene in these subjects. Finally, we can state that rs1527483, but not rs3212018, is associated with high body weight in young Czech subjects. PMID- 29446340 TI - Identification of vitamin B12 deficiency in vegetarian Indians. AB - The prevalence of a sub-clinical vitamin B12 deficiency in the vegetarians is high. Total serum vitamin B12 concentration alone does not reliably reflect vitamin B12 status. Holotranscobalamin (holo-TC) II is a bioactive B12 fraction promoting specific uptake of B12 by cells and the circulating concentration reflects the intake of B12, whereas total homocysteine (tHcy) indicates the metabolic ability. In this study, we investigated the diagnostic value of circulating holo-TC, B12, folate and homocysteine in vegetarians who were at risk of B12 deficiency. B12-related biomarkers were measured in 119 young, healthy graduate vegetarians. None was folate deficient. As per reported definition, half were B12 deficient; 70 % of males and 50 % of females had low plasma holo-TC concentrations; and 92 % of males and half of females had hyperhomocysteinaemia. None had any clinical signs of B12 deficiency. Receiver operating characteristic curve analysis demonstrated similar AUC at the B12 concentration of 100 and 150 pmol/l when holo-TC (0.777 and 0.784) and homocysteine (0.924 and 0.928) were used as variables. Cut-off value of 100 pmol/l resulted in the highest sensitivity of 77.78 % and specificity of 71.05 % with a predictive value of 19.6 pmol/l for holo-TC and a sensitivity of 82.72 % and specificity of 89.7 % with a predictive value of 21.7 umol/l for homocysteine. The combination of B12, holo-TC and tHcy improves the diagnostic accuracy at these cut-offs, and we suggest that for the young Indian vegetarians the cut-off for plasma B12 and holotrancobalamin is 100 pmol/l and 19.6 pmol/l, respectively, and for homocysteine it is 17.6 (females) and 27 umol/l (males) for identifying B12 deficiency. PMID- 29446341 TI - Emergency Management and Preparedness Training for Youth (EMPTY): The Results of the First Swedish Pilot Study. AB - OBJECTIVE: To examine the impact of a simulation training in raising a group of young students' personal and situational awareness in disasters and emergencies. METHODS: In total, 25 young students participated in two simulation scenarios representing two actual events, fire, and shooting, using a combination of two validated simulation training (Emergency Management and Preparedness Training for Youth [EMPTY]). The changes in their knowledge and awareness were evaluated by using questionnaires and the whole simulation was evaluated by three independent observers and a reference group. RESULTS: New concepts of emergency management, for example, evacuation, and barricading, could be trained in a safe environment. There was a significant increase in students' personal and situational awareness and their active engagement in the management of emergencies. CONCLUSION: EMPTY could raise the youth basic knowledge and ability to understand the concept of preparedness by being mentally prepared, available for collaboration, gaining a higher confidence, understanding the physical and psychological consequences of a major incident and the importance of their own safety.

AB - Weaning of piglets is associated with important changes in gut structure and function resulting from stressful events such as separation from the sow, moving to a new facility and dietary transition from a liquid to a solid feed. This may result in post-weaning diarrhoea and a decrease in feed intake and growth. In humans, the cyanobacterium Spirulina platensis (SP) and the freshwater microalga Chlorella vulgaris (CV) are known for their beneficial health effects. This study aimed to determine the effects of early oral administration of Spirulina and Chlorella in piglets on mucosal architecture and cytokine expression in the intestine around weaning, and consequences on growth performance and diarrhoea incidence. The experiment was conducted on 108 suckling piglets of 14 days of age (initial BW=4.9+/-0.7 kg) and weaned at 28 days of age (day 0). Animals received orally 385 mg/kg BW per day of SP or CV, or water (negative control (NC)) during 4 weeks from day -14 to day 14 and their growth performance was measured daily. After weaning, growth, feed intake and diarrhoea incidence were measured daily. Intestinal morphology and functionality were assessed at day -1, day 2, and day 14. During the suckling period, average daily gain (ADG) in SP piglets was higher, resulting in a higher weaning BW compared to NC and CV piglets (P0.10). Shorter ileal villi were measured in SP and CV piglets than in NC piglets (P<0.05). Cytokine expression did not differ between treatments in response to weaning. At day 14, IL-8 expression in the ileum was higher in SP piglets, while IL-1beta expression in the jejunum was higher in CV piglets (P<0.05). This study shows that Spirulina administration around weaning alleviates diarrhoea in weaned piglets, without marked modulation of local inflammation.

AB - Echinococcus granulosus is a helminth from the family Taeniidae, which causes cystic echinococcosis (CE) in humans and diverse livestock around the world. The identification of existing genotypes in different regions is a major step towards the prevention and establishment of control programmes for the disease. This study aimed to detect CE genotypes using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) of the internal transcribed spacer-1 (ITS1) gene and sequencing of the cytochrome c oxidase subunit 1 (Cox1) gene in isolates from the central part of Mazandaran province, northern Iran. Forty isolates were collected from sheep, 17 from cattle and 6 from human formalin fixed paraffin-embedded tissues (FFPE). The ITS1 and Cox1 genes were successfully amplified by PCR in 41 and 42 samples, respectively. PCR-RFLP and sequencing showed that all isolates had the G1-G3 genotypes in this study. Out of 31 isolates subjected to sequencing for the Cox1 gene, 80.7% had the G1 genotype. G2 (16.1%) and G3 (3.2%) genotypes were observed in five sheep and one cattle samples, respectively. Five human isolates were also sequenced for the ITS1 gene, which showed that all samples belonged to the G1 genotype. Ten haplotypes were determined among the isolates by alignment analysis of the Cox1 gene. In summary, this study demonstrated that G1 was the dominant genotype circulating between humans and livestock in the studied region. Furthermore, high genotypic diversity among the CE isolates was observed. PMID- 29446345 TI - Phase transition of intermetallic TbPt at high temperature and high pressure. AB - Here we present synchrotron-based x-ray diffraction experiments combined with diamond anvil cell and laser heating techniques on the intermetallic rare earth compound TbPt (Pnma and Z = 4) up to 32.5 GPa and ~1800 K. The lattice parameters of TbPt exhibit continuous compression behavior up to 18.2 GPa without any evidence of phase transformation. Pressure-volume data were fitted to a third order Birch-Murnaghan equation of state with V 0 = 175.5(2) A3, [Formula: see text] = 110(5) GPa and [Formula: see text] = 3.8(7). TbPt exhibits anisotropic compression with beta a > beta b > beta c and the ratio of axial compressibility is 2.50:1.26:1.00. A new monoclinic phase of TbPt assigned to the Pc or P2/c space group was observed at 32.5 GPa after laser heating at ~1800 K. This new phase is stable at high pressure and presented a quenchable property on decompression to ambient conditions. The pressure-volume relationship is well described by the second-order Birch-Murnaghan equation of state, which yields V 0 = 672(4) A3, [Formula: see text] = 123(6) GPa, which is about ~14% more compressible than the orthorhombic TbPt. Our results provide more information on the structure and elastic property view, and thus a better understanding of the physical properties related to magnetic structure in some intermetallic rare earth alloys. PMID- 29446343 TI - Cost-utility analysis of antiviral use under pandemic influenza using a novel approach - linking pharmacology, epidemiology and heath economics. AB - Simulation models are used widely in pharmacology, epidemiology and health economics (HEs). However, there have been no attempts to incorporate models from these disciplines into a single integrated model. Accordingly, we explored this linkage to evaluate the epidemiological and economic impact of oseltamivir dose optimisation in supporting pandemic influenza planning in the USA. An HE decision analytic model was linked to a pharmacokinetic/pharmacodynamics (PK/PD) - dynamic transmission model simulating the impact of pandemic influenza with low virulence and low transmissibility and, high virulence and high transmissibility. The cost utility analysis was from the payer and societal perspectives, comparing oseltamivir 75 and 150 mg twice daily (BID) to no treatment over a 1-year time horizon. Model parameters were derived from published studies. Outcomes were measured as cost per quality-adjusted life year (QALY) gained. Sensitivity analyses were performed to examine the integrated model's robustness. Under both pandemic scenarios, compared to no treatment, the use of oseltamivir 75 or 150 mg BID led to a significant reduction of influenza episodes and influenza-related deaths, translating to substantial savings of QALYs. Overall drug costs were offset by the reduction of both direct and indirect costs, making these two interventions cost-saving from both perspectives. The results were sensitive to the proportion of inpatient presentation at the emergency visit and patients' quality of life. Integrating PK/PD-EPI/HE models is achievable. Whilst further refinement of this novel linkage model to more closely mimic the reality is needed, the current study has generated useful insights to support influenza pandemic planning. PMID- 29446346 TI - Alkali-corrosion synthesis and excellent DSSC performance of novel jujube-like hierarchical TiO2 microspheres. AB - Novel jujube-like hierarchical TiO2 microspheres (HTMs) were synthesized by an alkali-corrosion process of titanium phosphate (Ti2O3(H2PO4)2 . 2H2O) microspheres. The hierarchical titanium phosphate microsphere (HTPM) intermediates consisting of nanoflakes with a thickness of 20 nm were firstly prepared by a facile hydrothermal method. After reacting with diluted NaOH at low temperature and atmospheric pressure, followed by subsequent acid washing and a calcination process, the HTPM intermediates were transformed to TiO2 with the microsphere morphology well retained, while the nanoflakes became porous, and some new nanowires were formed between the nanoflakes. Finally, HTMs consisting of porous nanoflakes and nanowires were obtained. The possible growth mechanisms of HTPMs and HTMs are discussed. The HTMs demonstrate high specific surface area and excellent light-scattering ability. The performance of the dye sensitized solar cells (DSSCs) of the HTMs synthesized under different conditions is studied, and a total conversion efficiency of up to 8.93% was obtained. The improved DSSC performance was attributed to the enhanced dye loading, light scattering, and charge transporting ability of the HTMs with a unique hierarchical nanostructure.

PMID- 29446348 TI - The effect of air stable n-doping through mild plasma on the mechanical property of WSe2 layers. AB - Two-dimensional transition metal dichalcogenides have been widely applied to electronic and optoelectronic device owing to their remarkable material properties. Many studies present the platform for regulating the contact resistance via various doping schemes. Here, we report the alteration of mechanical properties of few top layers of the WSe2 flake which are processed by air stable n-doping of N2O with a constant gas flow through mild plasma and present better manufacturability and friability. The single-line nanoscratching experiments on the WSe2 flakes with different doping time reveal that the manufacturable depths are positively correlated with the exposure time at a certain range and tend to be stable afterwards. Meanwhile, material characterization by x-ray photoelectron spectroscopy confirms that the alteration of mechanical properties is owing to the creation of Se vacancies and substitution of O atoms, which breaks the primary molecular structure of the WSe2 flakes. The synchronous Kelvin probe force microscopy and topography results of ROI nanoscratching of a stepped WSe2 sample confirmed that the depth of the degenerate doping is five layers, which was consistent with the single-line scratching experiments. Our results reveal the interrelationship of the mechanical property, chemical bonds and work function changes of the doped WSe2 flakes. PMID- 29446349 TI - Origin of noise in liquid-gated Si nanowire troponin biosensors. AB - Liquid-gated Si nanowire field-effect transistor (FET) biosensors are fabricated using a complementary metal-oxide-semiconductor-compatible top-down approach. The transport and noise properties of the devices reflect the high performance of the FET structures, which allows label-free detection of cardiac troponin I (cTnI) molecules. Moreover, after removing the troponin antigens the structures demonstrate the same characteristics as before cTnI detection, indicating the reusable operation of biosensors. Our results show that the additional noise is related to the troponin molecules and has characteristics which considerably differ from those usually recorded for conventional FETs without target molecules. We describe the origin of the noise and suggest that noise spectroscopy represents a powerful tool for understanding molecular dynamic processes in nanoscale FET-based biosensors. PMID- 29446350 TI - Image charge models for accurate construction of the electrostatic self-energy of 3D layered nanostructure devices. AB - Efficient analytical image charge models are derived for the full spatial variation of the electrostatic self-energy of electrons in semiconductor nanostructures that arises from dielectric mismatch using semi-classical analysis. The methodology provides a fast, compact and physically transparent computation for advanced device modeling. The underlying semi-classical model for the self-energy has been established and validated during recent years and depends on a slight modification of the macroscopic static dielectric constants for individual homogeneous dielectric regions. The model has been validated for point charges as close as one interatomic spacing to a sharp interface. A brief introduction to image charge methodology is followed by a discussion and demonstration of the traditional failure of the methodology to derive the electrostatic potential at arbitrary distances from a source charge. However, the self-energy involves the local limit of the difference between the electrostatic Green functions for the full dielectric heterostructure and the homogeneous equivalent. It is shown that high convergence may be achieved for the image charge method for this local limit. A simple re-normalisation technique is introduced to reduce the number of image terms to a minimum. A number of progressively complex 3D models are evaluated analytically and compared with high precision numerical computations. Accuracies of 1% are demonstrated. Introducing a simple technique for modeling the transition of the self-energy between disparate dielectric structures we generate an analytical model that describes the self-energy as a function of position within the source, drain and gated channel of a silicon wrap round gate field effect transistor on a scale of a few nanometers cross-section. At such scales the self-energies become large (typically up to ~100 meV) close to the interfaces as well as along the channel. The screening of a gated structure is shown to reduce the self-energy relative to un-gated nanowires. PMID- 29446351 TI - Dynamical quantum phase transitions: a review. AB - Quantum theory provides an extensive framework for the description of the equilibrium properties of quantum matter. Yet experiments in quantum simulators have now opened up a route towards the generation of quantum states beyond this equilibrium paradigm. While these states promise to show properties not constrained by equilibrium principles, such as the equal a priori probability of the microcanonical ensemble, identifying the general properties of nonequilibrium quantum dynamics remains a major challenge, especially in view of the lack of conventional concepts such as free energies. The theory of dynamical quantum phase transitions attempts to identify such general principles by lifting the concept of phase transitions to coherent quantum real-time evolution. This review provides a pedagogical introduction to this field. Starting from the general setting of nonequilibrium dynamics in closed quantum many-body systems, we give the definition of dynamical quantum phase transitions as phase transitions in time with physical quantities becoming nonanalytic at critical times. We summarize the achieved theoretical advances as well as the first experimental observations, and furthermore provide an outlook to major open questions as well as future directions of research. PMID- 29446352 TI - Deep learning for hybrid EEG-fNIRS brain-computer interface: application to motor imagery classification. AB - OBJECTIVE: Brain-computer interface (BCI) refers to procedures that link the central nervous system to a device. BCI was historically performed using electroencephalography (EEG). In the last years, encouraging results were obtained by combining EEG with other neuroimaging technologies, such as functional near infrared spectroscopy (fNIRS). A crucial step of BCI is brain state classification from recorded signal features. Deep artificial neural networks (DNNs) recently reached unprecedented complex classification outcomes. These performances were achieved through increased computational power, efficient learning algorithms, valuable activation functions, and restricted or back-fed neurons connections. By expecting significant overall BCI performances, we investigated the capabilities of combining EEG and fNIRS recordings with state-of the-art deep learning procedures. APPROACH: We performed a guided left and right hand motor imagery task on 15 subjects with a fixed classification response time of 1 s and overall experiment length of 10 min. Left versus right classification accuracy of a DNN in the multi-modal recording modality was estimated and it was compared to standalone EEG and fNIRS and other classifiers. MAIN RESULTS: At a group level we obtained significant increase in performance when considering multi-modal recordings and DNN classifier with synergistic effect. SIGNIFICANCE: BCI performances can be significantly improved by employing multi-modal recordings that provide electrical and hemodynamic brain activity information, in combination with advanced non-linear deep learning classification procedures.

AB - Background Depression is one of the leading psychiatric disorders of the world affecting a person's mood, physical health and behavior. It is not permanent and is neither a character flaw nor a lack in discipline for a person to be ashamed of. It is a disorder that is reliably diagnosed and successfully treated. Antidepressants are the standard and the most efficacious approach to treating people with depression. However, adherence to treatment is necessary for achieving effectiveness. The result of nonadherence is severe and may cause therapeutic failure resulting in poor quality of life. Objective To determine the medication adherence pattern in patients with depression and assess the factors associated with non-adherence to the prescribed antidepressant therapy. Method Patients meeting the inclusion criteria who were diagnosed with depression were taken for the study. Informed consent was taken from the patients or from their relatives in case of their incapability. They were then interviewed using structured questionnaire. Result Among the 60 patients included in the study, 78% of them were females. Most of the patients 43% (n=26) were prescribed with atypical antidepressants. Less number (37%) of the patients were adherent to the antidepressant therapy. 68% of the females were non adherent. 82% of housewives were not adherent to therapy. Forgetfulness was the main reason for missing dose in majority (50%) of the nonadherent patients. Conclusion Majority of the patients with depression were non-adherent to medication. Forgetfulness was the major reason for missing dose in these patients. PMID- 29446355 TI - Incidence and Associated Risk Factors of Postoperative Sore Throat in Tertiary Care Hospital. AB - Background Postoperative sore throat is a relatively minor complaint but a frequent postoperative complication of anesthesia. The incidence of postoperative sore throat varies from 0-50% in most research studies, but some report the incidence is as high as 51-100% following general anesthesia. Objective The aim of this study was to obtain the incidence and determine the associated risk factors of postoperative sore throat in tertiary care hospital. Method Three hundred and seventy six patients who underwent various surgeries under general anesthesia in Dhulikhel Hospital during a four month period were included. Using a predesigned questionnaire with follow up after 24-30 hours after extubation, data was collected. Sore throat was identified using a four point scale (0-3). Result Overall incidence of postoperative sore throat was 50.8%. Patient with airway device endotracheal tubes had the highest incidence (52.2%, 176 of 337), and patient with i-gel had a lower incidence of sore throat (33.3%, 7 of 21). Female patients reported more sore throat than male, more common with older age group and duration of anesthesia more than two hours. Increased incidence of postoperative sore throat was not associated with the type of surgery, number of intubation attempts, category of personnel performing airway managementr and use of oropharyngeal airway. Conclusion Postoperative sore throat is a common complication of airway instrumentation in general anesthesia that can lead to discomfort. The overall incidence of postoperative sore throat in this study was 50.8%. Endotracheal tube, female patients and increased duration of anesthesia were associated with increased postoperative sore throat rates. PMID- 29446356 TI - Pattern of Self-medication in Undergraduate Students at BP Koirala Institute of Health Sciences. AB - Background Self-medication is a growing health problem. It may lead to wastage of resources, emergence of antimicrobial resistance, adverse drug reactions and prolonged suffering. Little has been reported on the extent of self-medication practiced in medical students in Nepal. Objective To study the pattern, reason and perception of self-medication among undergraduate students. Method A cross sectional study was conducted among all undergraduate students at BP Koirala Institute of Health Sciences, Dharan, Nepal between April and May, 2015. After obtaining ethical clearance, pre-validated questionnaire was used to collect data. The date were analyzed and presented as frequency and percentage using SPSS version 11.5. Result Total of 520 students participated in the study with a mean age of 21.2+/-1.7 years. Prevalence of self-medication was found to be 48.3%. Most common cause for self-medication was common cold (53.3%). Nonsteroidal anti inflammatory drugs (78.9%) were the most commonly used medicine for self medication. The students commonly approached their seniors (50.2%) for the drug information. The most common adverse drug reaction experienced by the students was drowsiness (50.9%). Approximately one third of the students (33.2%) used to prescribe medicines to others. More than half of the students (53.8%) opined that self-medication is a part of self-care. Around one-fifth of the students (21.5%) students opined that self-medication is recommended by WHO. Conclusion Self medication is commonly practiced by undergraduate students. Nearly one third of the students also prescribe medicines to others. Nonsteroidal anti-inflammatory drugs are the most commonly used medicine as self-medication. The students need to be educated regarding appropriate safe-medication. PMID- 29446357 TI - To Access the Role of Serum Procalcitonin in Predicting the Severity of Acute Pancreatitis. AB - Background Acute Pancreatitis remains a common disorder with devastating consequences in severe form of disease. In this study we assessed serum procalcitonin for early prediction of severity of acute pancreatitis and compared it with multiple scoring systems and biomarkers. Objective This is a prospective comparative study in which 125 patients with diagnosis of acute pancreatitis were enrolled. All blood samples and imaging studies were obtained within 24-72 hours of admission and the severity was predicted. Method This is a prospective comparative study in which 125 patients with diagnosis of acute pancreatitis were enrolled. All blood samples and imaging studies were obtained within 24-72 hours of admission and the severity was predicted. Result Acute pancreatitis was graded severe in 54 patients and mild in 71 patients as per the Atlanta criteria. Receiver operating characteristic curve showed the area under curve of serum procalcitonin was higher (area under curve: 0.887, Confidence interval: 0.825 0.948) compared to computed tomography severity index scoring system (Area under curve: 0.841, Confidence interval: 0.771-0.911), Ranson's score (Area under curve: 0.796, Confidence interval: 0.715-0.876) and C-reactive protein (Area under curve: 0.717, Confidence interval: 0.628-0.8.7) in predicting the severity of acute pancreatitis. The best cut-off value of serum procalcitonin to predict severe acute pancreatitis was 0.9 ng/ml with 92.6% sensitivity, 80.3% specificity. The accuracy of serum procalcitonin (85.6%) was better than computed tomography severity index score (73.6 %), Ranson's score (76.8%) and C-reactive protein (64.8%). Conclusion Multifactorial scoring systems are complex and hard to use in clinical basis. Serum procalcitonin can be used as a promising single biomarker, easily done in all setup with better accuracy. And it is comparable to computed tomography severity index and Ranson's scores in earlier prediction of severity of acute pancreatitis. PMID- 29446358 TI - Clinical Profile of Diabetic Ketoacidosis in Adults in Dhulikhel Hospital. AB - Background Diabetic ketoacidosis is one of the life-threatening acute complications of diabetes mellitus. Despite the improvements in diabetic care, it remains a major clinical problem in clinical practice. Objective To assess the clinical and laboratory profile of adults with diabetic ketoacidosis in Dhulikhel hospital. Method This is a descriptive cross-sectional study including adult patients admitted in Dhulikhel hospital from July 2014 to July 2016 with the diagnosis of diabetic ketoacidosis according to the guidelines of American diabetes association. The hospital records of these patients were reviewed for their clinical and biochemical profiles. Result Forty eight patients fulfilled the criteria of diabetic ketoacidosis and were included in the study. Seventy three percent of patients had type 2 diabetes mellitus. Twenty three percent of the patients were cases of newly diagnosed diabetes mellitus. Polyuria and polydipsia as presenting complaint was more common in patients with type 1 diabetes mellitus (p=0.002) whereas fever was more common in type 2 diabetes mellitus patients (p=0.03). Majority of patients had normal serum sodium and potassium level. Forty two percent of the patients have high serum urea level and just over one third had high serum creatinine level. The most common precipitating factor of diabetic ketoacidosis for patients with type 1 diabetes mellitus was omission of insulin whereas in type 2 diabetic patients was infection. Conclusion Diabetic ketoacidosis is complication of both type 1 and type 2 diabetes mellitus. High degree of suspicion is needed for early detection of this life threatening condition especially in patients without history of diabetes mellitus. PMID- 29446359 TI - Evaluation of Risk Factors for Laryngopharyngeal Reflux among Sikkimese Population. AB - Background Laryngopharyngeal reflux is a global health problem and is associated with a huge economic burden and decreased quality of life. Studies describing the epidemiology of laryngopharyngeal reflux are sparse in India and south east Asia. This study becomes significant as it is being conducted in Sikkimese population who resides in high altitude have a different lifestyle. Objective To evaluate the risk factors for laryngopharyngeal reflux among Sikkimese origin. Method Patients of Sikkimese origin visiting Ear Nose Throat outpatient department Were administered with validated questionnaire. The patients were further subjected to validate Reflux symptom Index score. Indirect laryngoscopy was performed to calculate reflux finding score. Presence of laryngopharyngeal reflux was identified with patients having reflux symptom index and reflux finding score of greater or equal to 13 or more and 7 or more. Result Out of 200 subjects analysed, there were 77(38.5%) male and 123(61.5%) female. Heartburn and regurgitation were the most common symptom among the masses. Hoarseness and frequent throat clearance were the commonest laryngopharyngeal reflux symptoms. Various risk factors were computed as mentioned in the results column. Conclusion Study on the above mentioned population differed from rest of the country in terms of dietary habits. Fermented food was found to be one of the important risk factor for the development of laryngopharyngeal reflux in the sikkimise population. PMID- 29446360 TI - Factors Influencing Brain Drain among Nepalese Nurses. AB - Background Brain drain means migration of technically skilled people from one country to another country. Migration of health workers including nurses are the result of interplay of many push and pull factors. Push factors are those conditions that influence the nurses' decision to leave their own country. Conversely, pull factors are those conditions in a given country that attract nurses, influencing their movement to that country. Objective The objective of this study was to identify push and pull factors of brain drain among the Nepalese nurses. Method Descriptive cross sectional study was done among 228 Nepalese nurses working in five different countries in 2016 by using quota sampling technique. A self administered questionnaire consisting of structured four-point Likert scale was designed to collect information on push and pull factors of brain drain. Descriptive and inferential statistics were computed using SPSS version 16. Result Many of brain drained nurses had ranked very important push factor was personal ambition (72.8%) and very important pull factor was better job and career opportunity (77.2%). Majority of nurses working in Nepal had ranked very important push factor was lack of job and career opportunity (86.0%) and pull factor was better job and career opportunity (85.1%). All push and pull factors were significantly associated with brain drain. Conclusion Most of the Nepalese nurses were forced to go abroad due to personal ambition, followed by low salary, and lack of job and career opportunity. Nurse migration out of Nepal is likely to persist and even increase if underlying factors aren't properly resolved. PMID- 29446361 TI - Outcome of Patients with Meningitis and Encephalitis at Tertiary Care Hospital in Eastern Nepal. AB - Background There are several etiologies of meningitis and encephalitis which must be considered in any patient presenting with fever, headache, neck stiffness and vomiting. Bacterial meningitis and viral encephalitis are medical emergencies and need urgent attention and treatment. Any delay in diagnosis and treatment has been shown to increase morbidity and mortality. Some of the survivors also have neurological sequel with a need for long term physical and occupational rehabilitation. Objective To find out common causes of meningitis, encephalitis, predictors of outcome, early and late complications of meningitis and encephalitis at Tertiary Care Hospital in Eastern Nepal. Method It is a prospective study which was conducted at Nobel Medical College Teaching Hospital from April 2015 to March 2016. Result A total of 52 patients participated in the study. Bacterial meningitis was the most common type of neuroinfection (40.4%) followed by tubercular meningitis (27%), viral encephalitis (17.3%) and viral meningitis (15.4%). Pneumococcus was the most common identified cause of meningitis accounting for 28.9% of bacterial meningitis. Japanese encephalitis was the most common identifiable cause of encephalitis accounting for 33% of cases. Low Glasgow Coma Scale at admission was significantly associated with worse neurological outcome (P<0.001). Similarly, high white blood cell count in blood was associated with worse neurological outcome (P=0.001). Conclusion Meningitis and encephalitis are neurological emergency. Prompt diagnosis and treatment is needed to improve survival. Neurological sequel is common after those infections which require long term rehabilitation. PMID- 29446362 TI - A Survey on Oral Health and Practice of Nepalese in Areas Affected by Earthquake in 2015. AB - Background Understanding post-earthquake oral health indicators is essential for developing oral health interventions of the victims. Presumably, due to a geographic difficulty, there has been no investigation to reveal the oral health status of individuals after the Gorkha earthquake in Nepal. Objective The main objective was to determine the oral health and practice of Nepalese affected by earthquake in April-May, 2015. Method The epidemiological cross sectional study was done at 5 different districts (Sindhupalchok, Dadhing, Bhaktapur, Kathmandu and Kavre) of Nepal from September till November, 2015. Altogether 500 subjects aged form 16 to 80 years of age living in the transitional shelters community were included in earthquake-affected areas. Different parameters were studied from past and present medical and dental problems, habits, oral hygiene habits. DMFT, gingival index, periodontal index were studied and correlation was studied among them. Result It shows that 98% of the participants had plaque and 96.4% of the participants had calculus. Mean decayed was 9, mean missing was 4 and mean filling was 1. 22.60% of the participants had score 0, 34.8% had score 1, 34% had score 2 and 8.60% had score 3 of mean gingivitis index. 10% of the participants showed score 0, 36% showed score 1, 35% showed score 2, 10.2% showed score 3 and 8.2% showed score 4 of mean periodontal index. Moreover, significant correlation was observed among DMFT index, gingival index and periodontal index (p<0.001). Conclusion The oral health care practice, oral hygiene habits, nutritional intake of the people have been affected in the earthquake affected areas. It showed high caries index, gingival index and periodontal index in earthquake affected people suggesting further efforts are needed for an oral health improvement. Data from this study may be used as basic information for oral health planning and future steps in oral health care preventive and therapeutic programs. PMID- 29446363 TI - Histopathological Analysis of Non-Neoplastic Superficial Lymphadenopathies. AB - Background Lymphadenopathies are the clinical manifestation of enlargement of lymph nodes which are a common occurrence and are processes of lymph nodes in response to a variety of exogenous and endogenous stimulants. The vast majority of enlarged lymph nodes are non- neoplastic. Objective The objective of the study is to analyze the spectrum of non-neoplastic lesions of superficial lymphadenopathies with their histomorphological features. Method This was a retrospective hospital based study done in the department of Pathology. All cases of superficial lymph node biopsies received during a period of 7 years were retrieved and divided into 2 broad categories: neoplastic and non-neoplastic. The latter group is the material for the present study. The diagnosis was made on morphological basis. Result Of all the 268 superficial lymph node biopsies, 25.4% (68 cases) were neoplastic and 74.6% (200 cases) were non-neoplastic. The non neoplastic cases were further categorized into non-infectious 60.5% (121 cases) and infectious 39.5% (79 cases). Neck node (70%) was the most common site of involvement. There were 102 male and 98 female patients with male to female ratio 1.04:1. The age range of the patients was 2 years to 83 years with a mean of 27.16 years and most common being 11-20 years 29% (58 cases). Majority of the cases were non-specific reactive lymphadenitis 84.3% (102 cases) followed by tuberculosis 36.5% (73 cases). Conclusion The major cause for the superficial lymphadenopathy was found to be non-neoplastic etiology with slight male predominance. Reactive lymphadenitis was the leading cause unlike the studies done in other Asian and Tropical countries where tuberculosis was more common. PMID- 29446364 TI - Characterization of Seasonal Influenza Virus Type and Subtypes Isolated from Influenza Like Illness Cases of 2012. AB - Background Seasonal influenza is one of the increasing public health burdens in Nepal. Objective The objective of this study was to isolate and characterize the influenza virus type and subtypes of Nepal. Method A total of 1536 throat swab specimens were collected from January to December 2012. Total ribonucleic acid was extracted using Qiagen viral nucleic acid extraction kit and polymerase chain reaction assay was performed following the US; CDC Real-time PCR protocol. Ten percent of positive specimens were inoculated onto Madin-Darby Canine Kidney cells. Isolates were characterized by using reference ferret antisera. Result Of the total specimens (n=1536), influenza virus type A was detected in 196 (22%) cases; of which 194 (99%) were influenza A (H1N1) pdm09 and 2 (1 %) were influenza A/H3 subtype. Influenza B was detected in 684 (76.9%) cases. Influenza A (H1N1) pdm09, A/H3 and influenza B virus were antigenically similar to the recommended influenza virus vaccine candidate of the year 2012. Although sporadic cases of influenza were observed throughout the year, peak was observed during July to November. Conclusion Similar to other tropical countries, A (H1N1) pdm09, A/H3 and influenza B viruses were co-circulated in Nepal. PMID- 29446365 TI - Determination of Sex from the Foramen Magnum using 3DCT: A Nepalese Study. AB - Background Identification is of utmost importance in any medicolegal investigation with sex determination being one of the principle indicators of identity. Sexing of bones becomes easy when the skeletal remains are complete. However, the problem arises when the bones are fragmented. Many researchers have undertaken several studies in different populations to determine the sex with reasonable accuracy using numerous measurements of the skull including those of the foramen magnum. Objective The present study was aimed to find the sexual dimorphism of the foramen magnum in the Nepalese population by analyzing the antero-posterior length, transverse diameter and area of the foramen magnum. Method The antero-posterior length and transverse diameter of the foramen magnum were measured using three-dimensional computed tomography (3DCT) images of the head in a cohort of 100 Nepalese subjects. Radinsky's and Teixeria's formulae were used to calculate the area of the foramen magnum. Discriminate function analysis was used to analyze sex differences. Result Mean values of antero posterior length and transverse diameter of the foramen magnum in males were higher than in females. The mean of the area calculated using Radinsky's formula was smaller than that calculated by Teixeira's formula and the areas calculated were higher in males. The measurements of the foramen magnum and the areas calculated showed significant difference (p<0.001) between males and females. Discriminate function analysis for the measurements of the foramen magnum and the areas calculated showed high predictability for both the sexes. Discriminate function analysis showed a maximum predictability of 75%. Conclusion Considering the percent of predictability of sex from the various variables related to the foramen magnum in the Nepalese population, it can be concluded that its restricted applicability in forensic investigations should be constrained to cases of fragmentary skull bases.

AB - Background Impacted teeth are those that have erupted or are partially erupted and will not assume a normal arch relationship with opposing and adjacent teeth and tissues. Objective To evaluate the incidence and pattern of mandibular impacted third molars in patients of Dhulikhel Hospital. Method A retrospective study was conducted from March 2016 to November 2016 and reviewed 581 orthopantomograms and clinical records of patients who presented to the Department of Oral and Maxillofacial Surgery. The angulation of impaction was measured using Winter's classification and the level and position of impacted third molar was recorded using Pell and Gregory classification system. The etiology for extraction was recorded from previous clinical records. Result In this study, incidence of impaction was more prevalent in females. The most common pattern of impaction was mesioangular followed by horizontal, vertical, distoangular and others. The most common cause of extraction was caries in the third molar. There was no significant difference between the pattern of impaction in the right and left sides of the mandible. Conclusion Classifications of impacted mandibular third molars can be effectively used to predict the surgical difficulty and to evaluate the risk of postoperative complications. Therefore, this study highlights the importance of evaluation of pattern, type and class of impaction in Nepalese population giving a high clinical significance.

Mean age of the patients was 30.87 +/- 19.25 years. Among them 205 patients showed abnormal CT findings, scalp injury being the commonest one, followed by skull fracture. 60 patients showed abnormal intracranial findings. There was significant correlation of skull fracture and abnormal intracranial findings in this study. Conclusion This study provided the normal and abnormal CT findings in head of the craniocerebral trauma patients in Dhulikhel Hospital. Abnormal CT findings were predominantly extra-cranial and were overlapping with intracranial abnormal findings. PMID- 29446368 TI - Awareness and Knowledge of Oral Cancer among Medical Students in Kathmandu University School of Medical Sciences. AB - Background Oral cancer is a major public health problem worldwide. It has high mortality rates and chances of survival is relatively superior when detected early. Lack of knowledge and awareness about oral cancer among medical students may contribute to delay in diagnosis and treatment. Objective To assess awareness and knowledge of oral cancer among medical students. Method A cross-sectional study conducted among 286 students by Department of Otorhinolaryngology and Head & Neck surgery, Kathmandu University School of Medical sciences between July to August 2016.

PMID- 29446370 TI - Correlation between Preoperative High Resolution Computed Tomography (CT) Findings with Surgical Findings in Chronic Otitis Media (COM) Squamosal Type. AB - Background The exact role of High resolution computed tomography (HRCT) temporal bone in preoperative assessment of Chronic suppurative otitis media atticoantral disease still remains controversial. Objective To evaluate the role of high resolution computed tomography temporal bone in Chronic suppurative otitis media atticoantral disease and to compare preoperative computed tomographic findings with intra-operative findings. Method Prospective, analytical study conducted among 65 patients with chronic suppurative otitis media atticoantral disease in Department of Radiodiagnosis, Kathmandu University Dhulikhel Hospital between January 2015 to July 2016. The operative findings were compared with results of imaging. The parameters of comparison were erosion of ossicles, scutum, facial canal, lateral semicircular canal, sigmoid and tegmen plate along with extension of disease to sinus tympani and facial recess. Sensitivity, specificity, negative predictive value, positive predictive values were calculated. Result High resolution computed tomography temporal bone offered sensitivity (Se) and specificity (Sp) of 100% for visualization of sigmoid and tegmen plate erosion. The performance of HRCT in detecting malleus (Se=100%, Sp=95.23%), incus (Se=100%,Sp=80.48%) and stapes (Se=96.55%, Sp=71.42%) erosion was excellent. It offered precise information about facial canal erosion (Se=100%, Sp=75%), scutum erosion (Se=100%, Sp=96.87%) and extension of disease to facial recess and sinus tympani (Se=83.33%,Sp=100%). high resolution computed tomography showed specificity of 100% for lateral semicircular canal erosion (Sp=100%) but with low sensitivity (Se=53.84%). Conclusion The findings of high resolution computed tomography and intra-operative findings were well comparable except for lateral semicircular canal erosion. high resolution computed tomography temporal bone acts as a road map for surgeon to identify the extent of disease, plan for appropriate procedure that is required and prepare for potential complications that can be encountered during surgery.

AB - Aluminium phosphide is one of the most common poisons used for suicide in an agricultural country like India. Death is usually due to myocarditis which occurs within few hours of ingestion. There are many late complications reported in medical literature, however toxic effects on the gastrointestinal system, particularly corrosive action leading to massive haemorrhage is rarely reported. A 30 year old male developed upper gastrointestinal bleeding on the second day after consumption of aluminium phosphide. An exploratory laprotomy was done followed by adhesinolysis, gastrostomy closure with feeding jejunostomy and drainage. He died after eight days of ingestion. The autopsy findings of this rarely reported case along with review of literature on corrosive action of Aluminium Phosphide is discussed.

Both tissues share the same anatomical origin. Sometimes exact etiological passage of disease process cannot be traced; nevertheless traditional and newer treatment modalities must be employed to ensure best treatment possibilities. Patient reported with pain and pus exudates in upper left anterior region. Past dental history revealed no history of trauma. Initial examination revealed draining sinus with respect to 22. However, no Caries and pockets could be detected. Tooth was nonresponsive to vitality test. Patient symptoms did not relieve even two months after completion of RCT. Apical surgery was planned. Apicectomy was done and osseous defect was filled with PRF coagulum. Patient was followed up every three months and showed complete resolution of all symptoms. Radiographs showed complete resolution of osseous defect in nine months. PRF can be used to enhance bone augmentation in treatment of periapical defects as a potential treatment alternative for faster healing. PMID- 29446377 TI - Therapeutic Effects of a Long-Acting Cholinergic Receptor Blocker, Tiotropium Bromide, on Asthma. AB - BACKGROUND The aim of this study was to evaluate the therapeutic effects of tiotropium bromide on asthma. MATERIAL AND METHODS A total of 160 patients with moderate persistent asthma were randomly divided into 4 groups (n=40): the 3 control groups were given fluticasone propionate aerosol (group A), salmeterol fluticasone propionate inhalant (group B), and tiotropium bromide inhalation powder combined with salmeterol-fluticasone propionate inhalant (group C), respectively, and the experimental group received tiotropium bromide inhalation powder combined with fluticasone propionate aerosol (group D) and salbutamol was used to relieve symptoms when necessary. RESULTS After 8 weeks of treatment, the pulmonary function of group D, which was significantly better than those of group A (P<0.05), was similar to those of groups B and C (P>0.05). Group D had significantly better asthma control test scores and nighttime symptom scores than in group A (P<0.05), without significant differences from those of group B or group C (P>0.05). The number of times salbutamol was used to alleviate symptoms was significantly different (P<0.05) between group D and group A (P<0.05), as well as between group C and group D (P<0.05). Groups D and B had similar results (P>0.05). IL-13 levels in induced sputum had significant differences (P<0.05). The levels in group D, which were higher than those of groups A and B (P<0.05), were similar to those of group C (P>0.05). CONCLUSIONS Tiotropium bromide combined with fluticasone propionate improved the respiratory function and quality of life, and is a new therapy for moderate, persistent asthma. PMID- 29446378 TI - Freezing on a sphere. AB - The best understood crystal ordering transition is that of two-dimensional freezing, which proceeds by the rapid eradication of lattice defects as the temperature is lowered below a critical threshold. But crystals that assemble on closed surfaces are required by topology to have a minimum number of lattice defects, called disclinations, that act as conserved topological charges-consider the 12 pentagons on a football or the 12 pentamers on a viral capsid. Moreover, crystals assembled on curved surfaces can spontaneously develop additional lattice defects to alleviate the stress imposed by the curvature. It is therefore unclear how crystallization can proceed on a sphere, the simplest curved surface on which it is impossible to eliminate such defects. Here we show that freezing on the surface of a sphere proceeds by the formation of a single, encompassing crystalline 'continent', which forces defects into 12 isolated 'seas' with the same icosahedral symmetry as footballs and viruses. We use this broken symmetry aligning the vertices of an icosahedron with the defect seas and unfolding the faces onto a plane-to construct a new order parameter that reveals the underlying long-range orientational order of the lattice. The effects of geometry on crystallization could be taken into account in the design of nanometre- and micrometre-scale structures in which mobile defects are sequestered into self ordered arrays. Our results may also be relevant in understanding the properties and occurrence of natural icosahedral structures such as viruses. PMID- 29446379 TI - Astroglial Kir4.1 in the lateral habenula drives neuronal bursts in depression. AB - Enhanced bursting activity of neurons in the lateral habenula (LHb) is essential in driving depression-like behaviours, but the cause of this increase has been unknown. Here, using a high-throughput quantitative proteomic screen, we show that an astroglial potassium channel (Kir4.1) is upregulated in the LHb in rat models of depression. Kir4.1 in the LHb shows a distinct pattern of expression on astrocytic membrane processes that wrap tightly around the neuronal soma. Electrophysiology and modelling data show that the level of Kir4.1 on astrocytes tightly regulates the degree of membrane hyperpolarization and the amount of bursting activity of LHb neurons. Astrocyte-specific gain and loss of Kir4.1 in the LHb bidirectionally regulates neuronal bursting and depression-like symptoms. Together, these results show that a glia-neuron interaction at the perisomatic space of LHb is involved in setting the neuronal firing mode in models of a major psychiatric disease. Kir4.1 in the LHb might have potential as a target for treating clinical depression. PMID- 29446380 TI - Pulsating aurora from electron scattering by chorus waves. AB - Auroral substorms, dynamic phenomena that occur in the upper atmosphere at night, are caused by global reconfiguration of the magnetosphere, which releases stored solar wind energy. These storms are characterized by auroral brightening from dusk to midnight, followed by violent motions of distinct auroral arcs that suddenly break up, and the subsequent emergence of diffuse, pulsating auroral patches at dawn. Pulsating aurorae, which are quasiperiodic, blinking patches of light tens to hundreds of kilometres across, appear at altitudes of about 100 kilometres in the high-latitude regions of both hemispheres, and multiple patches often cover the entire sky. This auroral pulsation, with periods of several to tens of seconds, is generated by the intermittent precipitation of energetic electrons (several to tens of kiloelectronvolts) arriving from the magnetosphere and colliding with the atoms and molecules of the upper atmosphere. A possible cause of this precipitation is the interaction between magnetospheric electrons and electromagnetic waves called whistler-mode chorus waves. However, no direct observational evidence of this interaction has been obtained so far. Here we report that energetic electrons are scattered by chorus waves, resulting in their precipitation. Our observations were made in March 2017 with a magnetospheric spacecraft equipped with a high-angular-resolution electron sensor and electromagnetic field instruments. The measured quasiperiodic precipitating electron flux was sufficiently intense to generate a pulsating aurora, which was indeed simultaneously observed by a ground auroral imager.

AB - The N-methyl-d-aspartate receptor (NMDAR) antagonist ketamine has attracted enormous interest in mental health research owing to its rapid antidepressant actions, but its mechanism of action has remained elusive. Here we show that blockade of NMDAR-dependent bursting activity in the 'anti-reward center', the lateral habenula (LHb), mediates the rapid antidepressant actions of ketamine in rat and mouse models of depression. LHb neurons show a significant increase in burst activity and theta-band synchronization in depressive-like animals, which is reversed by ketamine. Burst-evoking photostimulation of LHb drives behavioural despair and anhedonia. Pharmacology and modelling experiments reveal that LHb bursting requires both NMDARs and low-voltage-sensitive T-type calcium channels (T-VSCCs). Furthermore, local blockade of NMDAR or T-VSCCs in the LHb is sufficient to induce rapid antidepressant effects. Our results suggest a simple model whereby ketamine quickly elevates mood by blocking NMDAR-dependent bursting activity of LHb neurons to disinhibit downstream monoaminergic reward centres, and provide a framework for developing new rapid-acting antidepressants. PMID- 29446382 TI - A spin-orbital-entangled quantum liquid on a honeycomb lattice. AB - The honeycomb lattice is one of the simplest lattice structures. Electrons and spins on this simple lattice, however, often form exotic phases with non-trivial excitations. Massless Dirac fermions can emerge out of itinerant electrons, as demonstrated experimentally in graphene, and a topological quantum spin liquid with exotic quasiparticles can be realized in spin-1/2 magnets, as proposed theoretically in the Kitaev model. The quantum spin liquid is a long-sought exotic state of matter, in which interacting spins remain quantum-disordered without spontaneous symmetry breaking. The Kitaev model describes one example of a quantum spin liquid, and can be solved exactly by introducing two types of Majorana fermion. Realizing a Kitaev model in the laboratory, however, remains a challenge in materials science. Mott insulators with a honeycomb lattice of spin orbital-entangled pseudospin-1/2 moments have been proposed, including the 5d electron systems alpha-Na2IrO3 (ref. 5) and alpha-Li2IrO3 (ref. 6) and the 4d electron system alpha-RuCl3 (ref. 7). However, these candidates were found to magnetically order rather than form a liquid at sufficiently low temperatures, owing to non-Kitaev interactions. Here we report a quantum-liquid state of pseudospin-1/2 moments in the 5d-electron honeycomb compound H3LiIr2O6. This iridate does not display magnetic ordering down to 0.05 kelvin, despite an interaction energy of about 100 kelvin. We observe signatures of low-energy fermionic excitations that originate from a small number of spin defects in the nuclear-magnetic-resonance relaxation and the specific heat. We therefore conclude that H3LiIr2O6 is a quantum spin liquid. This result opens the door to finding exotic quasiparticles in a strongly spin-orbit-coupled 5d-electron transition-metal oxide.

AB - Highly stretchable strain sensors that are capable of collecting complex multi axial, multidimensional strain information in real time are crucial in practical applications for human motion detection. Here we present a highly sensitive and selective multidimensional resistive strain sensor based on a monolithic integration of a stiffness-variant stretchable substrate and sensing film comprising a cross-shaped silver nanowire percolation network in a single device. The multidimensional strain sensor efficiently distinguishes strains in various directions with a large gauge factor (GF) of >20 and a wide strain-detectable range of up to 60%. The sensor also features a maximum difference in GF between the x- and y-axes of >20 and long-term performance stability for up to 500 strain cycles. The practicality of the sensor as a human motion detector is demonstrated by attaching it directly to a part of the human body and measuring the multidimensional strains that occur during motions in real time.

AB - The carbon nanotube aerogel (CNA) with an ultra-low density, three-dimensional network nanostructure, superior electronic conductivity and large surface area is being widely employed as a catalytic electrode and catalytic support. Impressively, dye-sensitized solar cells (DSSCs) assembled with a CNA counter electrode (CE) achieved a maximum power conversion efficiency (PCE) of 8.28%, which exceeded that of the conventional platinum (Pt)-based DSSC (7.20%) under the same conditions. Furthermore, highly dispersed CoS2 nanoparticles endowed with excellent intrinsic catalytic activity were hydrothermally incorporated to form a CNA-supported CoS2 (CNA-CoS2) CE, which was due to the large number of catalytically active sites and sufficient connections between CoS2 and the CNA. The electrocatalytic ability and stability were systematically evaluated by cyclic voltammetry (CV), electrochemical impedance spectra (EIS) and Tafel polarization, which confirmed that the resultant CNA-CoS2 hybrid CE exhibited a remarkably higher electrocatalytic activity toward I3- reduction, and faster ion diffusion and electron transfer than the pure CNA CE. Such cost-effective DSSCs assembled with an optimized CNA-CoS2 CE yielded an enhanced PCE of 8.92%, comparable to that of the cell fabricated with the CNA-Pt hybrid CE reported in our published literature (9.04%). These results indicate that the CNA-CoS2 CE can be considered as a promising candidate for Pt-free CEs used in low-cost and high performance DSSCs. PMID- 29446419 TI - A semi-permanent and durable nanoscale-crack-based sensor by on-demand healing. AB - Although sensitivity and durability are desirable in a sensor, both of them cannot be easily achieved. Site-specific and effective signal acquisition on the limited area of a sensor inevitably allows fatigue accumulation and contamination. For example, an ultrasensitive nanoscale-crack-based sensor for detecting a mechanical stimulus with tremendous sensitivity (a gauge factor greater than 2000 under 2% strain), yet limited durability (up to a few thousand stretching cycles in tensile tests) has been presented previously. Herein, we suggest a simple yet robust nanoscale-crack-based sensor that achieves remarkable durability through the use of a self-healable polymer. The self-healable polymer helps the crack gap recover and maintain high stability for 1 million cycles under 2% strain. Moreover, site-specific recovery with infrared light irradiation was demonstrated with monolithic arrayed sensors. The proposed strategy provides a unique solution to achieving highly enhanced durability and high mechanosensitivity, which are typically incompatible. PMID- 29446420 TI - Newly synthesized quercetin derivatives as corrosion inhibitors for mild steel in 1 M HCl: combined experimental and theoretical investigation. AB - To evaluate the corrosion inhibition efficacy of the derivatives of naturally available organics, mono and di-4-((2-hydroxyethyl)piperazin-1-yl)methyl derivatives of quercetin, a flavonoid, have been synthesized. Their potential as anti-corrosive agents is assessed for mild steel in 1 M HCl employing the weight loss technique as well as electrochemical methods. Comparing the rate of corrosion in uninhibited and inhibited solutions as a function of temperature, the thermodynamic parameters of adsorption of these derivatives on mild steel surfaces and the kinetic parameters of the corrosion process are evaluated. These parameters together with information derived from electrochemical methods are further used to ascertain the mechanism of corrosion and mode of adsorption of inhibitors with intricate detail. Density functional theory (DFT) calculations were employed to explain the relative corrosion inhibition propensity between the studied mono and di quercetin derivatives. Molecular dynamics (MD) simulations were carried out to obtain the interaction energy between the inhibitor molecules and the metal surface. Results show that both derivatives, acting as mixed-type inhibitors, exert profound anti-corrosive influence (around 95% inhibition efficiency at 1 mM concentration at 313 K). Theoretical studies suggest that the trihydroxy chromone ring and dihydroxy phenyl ring of quercetin maintain a planar orientation with respect to each other and are adsorbed on the metal surface (mostly chemisorption).

Taking a Cu(pop)(pz2Bph2) crystal as a typical TADF molecular model, we computed the conversion and decay rates of the first excited singlet state (S1) and triplet state (T1) at different temperatures by employing the thermal vibration correlation function (TVCF) approach. For the consideration of the solid-state environment, a methodology, which is based on the combination of a nonempirical, optimally tuned range-separated hybrid functional with the polarizable continuum model, was applied. Our calculated results are in excellent agreement with the experimentally available data. It is found that the reverse intersystem crossing (RISC) from T1 to S1 proceeds at a rate of kRISC = 6.34 * 105 s-1 and can compete with the radiative decay rate (k = 3.29 * 103 s-1) and nonradiative intersystem crossing rate (k = 1.48 * 102 s-1) of T1 at 300 K. This implies that the S1 state can be repopulated from the T1 state, TADF should be observed and the TADF decay time was found to be tau (300 K) = 9.68 MUs by fitting calculations. In addition, the calculations indicate that the free rotation of the phenylene ring in the pop ligand can provide an important channel to energy conversion between T1 and S1. But, at a low temperature of T < 100 K, the situation will experience a larger change. The RISC rate becomes very small, kRISC ? k or kISC, and it cannot induce an occurrence of delayed fluorescence. As a consequence, Cu(pop)(pz2Bph2) is a highly attractive candidate for applications of TADF.

AB - Fast, low-cost and reliable DNA sequencing is one of the most desirable innovations in recent years, which can pave the way for high throughput, label free and inexpensive personalized genome sequencing techniques. Although graphene based nanopore devices hold great promise for next-generation DNA sequencing, it is still a challenging problem to detect different DNA sequences efficiently and accurately. In the present work, the translocation of four homogeneous DNA strands (i.e., poly(A)20, poly(C)20, poly(G)20, and poly(T)20) through the functionalized graphene nanopores is investigated by all-atom molecular dynamic simulations. Interestingly, it is found that the four types of bases could be identified by different ionic currents when they pass through the hydrogenated and hydroxylated pores. For the hydrogenated nanopore, the difference in the ionic current for the four bases is mainly attributed to the different electrostatic interactions between the base and the ion. For the hydroxylated nanopore, apart from the electrostatic interactions, the position of a nucleotide inside the nanopore and the dwell time of an ion around the nucleotide also play an important role in the ionic current. The present study could be helpful to better design a novel device for DNA sequencing in the future. PMID- 29446424 TI - Adsorption of amphiphilic graft copolymers in solvents selective for the grafts on a lyophobic surface: a coarse-grained simulation study. AB - The sorption of graft copolymers on surfaces attractive only for the backbone and its effect on the conformational behavior of adsorbed/desorbed chains in solvents good for the grafts and poor for the backbone was studied by coarse-grained computer simulations. It was found that the sorption and conformational behavior are very complex and are results of an intricate interplay of solvent quality (polymer-solvent interactions) and solvent strength (polymer-surface vs. solvent surface interactions). Increasing grafting density and length of grafts protect the backbone against adsorption, but the behavior is non-trivial. A decrease in solvent quality promotes the adsorption, because it lowers the overall solubility, but the backbone collapses and the probability of backbone-surface contacts decreases, which simultaneously hinders the adsorption. The results of simulations are presented in the form of phase diagrams depicting the decisive features of the conformational and sorption behavior. PMID- 29446425 TI - Electronic structure calculations and nonadiabatic dynamics simulations of excited-state relaxation of Pigment Yellow 101. AB - Pigment Yellow 101 (PY101) is widely used as a typical pigment due to its excellent excited-state properties. However, the origin of its photostability is still elusive. In this work, we have systematically investigated the photodynamics of PY101 by performing combined electronic structure calculations and trajectory-based nonadiabatic dynamics simulations. On the basis of the results, we have found that upon photoexcitation to the S1 state, PY101 undergoes an essentially barrierless excited-state intramolecular single proton transfer generating an S1 keto species. In the keto region, there is an energetically accessible S1/S0 conical intersection that funnels the system to the S0 state quickly. In the S0 state, the keto species either goes back to its trans-enol species through a ground-state reverse hydrogen transfer or arrives at the cis keto region. In addition, we have found an additional excited-state decay channel for the S1 enol species, which is directly linked to an S1/S0 conical intersection located in the enol region. This mechanism has also been confirmed by our dynamics simulations, in which about 54% of the trajectories decay to the S0 state via the enol S1/S0 conical intersection; while the remaining ones employ the keto S1/S0 conical intersection. The gained mechanistic information helps us understand the photostability of the PY101 chromophore and its variants with the same molecular scaffold. PMID- 29446426 TI - Time dependent aggregation induced emission enhancement and the study of molecular packing in closely related azo-phenol BODIPY species. AB - Fluorescent azo-phenol BODIPYs (1-3) have been obtained by the substituent ( OCH3/-CH3) directed synthesis of ortho (L1) and para (L2-L3) azo-phenol aldehydes. These display aggregation caused quenching (ACQ, 1) and aggregation induced emission enhancement (AIEE, 2 and 3) depending on the position of azo relative to the phenolic hydroxyl group. An intriguing time dependent morphological transition from nanospheres to ordered nanorods and subsequent emission changes in AIEE active azo-phenol BODIPYs have been successfully realized by time dependent fluorescence, scanning electron (SEM), transmission electron (TEM) and fluorescence optical microscopy (FOM) studies. The existence of one-dimensional (1D) nanorods as ultimate species in these compounds (2-3) has been supported by crystal packing patterns. Diverse aggregated forms and hierarchical nanostructures have been related to variable extents of fluorescence enhancement. The plausible charge transfer process and its role in AIEE have been supported by DFT studies. PMID- 29446427 TI - Nickel(iii)-mediated oxidative cascades from a thiol-bearing nickel(ii) precursor to the nickel(iv) product. AB - A nickel(ii) complex, Ni(HPS2)2 (1) that contains two pendant thiols, is rapidly aerobically oxidized in the presence of an amine to produce a diamagnetic nickel(iv) complex, Ni(PS2)2 (2). This process was investigated spectroscopically at a temperature of -80 degrees C. Absorption spectra revealed that the deprotonation of one pendant thiol of 1 triggers an oxidative cascade; EPR findings indicate that single-spin species comprised of nickel(iii) intermediates are produced in the reaction solution. Possible reaction routes were examined by DFT calculations, in which an energy profile indicates that (i) a self-driven formation of 2 favors a sequential proton/electron transfer pathway; (ii) kinetically trapped nickel(iii) intermediates may respond to the specificity of the coordination of 2 in a cis-form. The overall findings help one to rationalize how a nickel(ii) precursor can be oxidized by O2 to a higher oxidation state. PMID- 29446428 TI - p-Type conductivity of hexagonal boron nitride as a dielectrically tunable monolayer: modulation doping with magnesium. AB - Hexagonal boron nitride (h-BN) is the widest band gap 2D material (>6 eV), which has attracted extensive attention. For exploring potential applications in optoelectronic devices, electrical conductivity modulation (n or p type) is of extreme importance. Here, we report the achievement of a large-scale and high quality h-BN monolayer with p-type conductivity by modulation doping of Mg using a low pressure chemical vapor deposition method. A large-scale monolayer h-BN (>10 inches) was grown by using a wound Cu foil roll on a multi-prong quartz fork. Magnesium nitride is used as a dopant precursor in a separate line due to its appropriate melting point and decomposition temperature. Density functional theory calculations revealed that the acceptor level introduced by Mg is almost pinned into the valence band and the activated holes are highly delocalized into the surrounding h-BN lattices. The h-BN:Mg monolayer showed a p-type conductivity with a considerable surface current of over 12 MUA and a hole density of 1.7 * 1014 cm-2. The dielectrically tunable h-BN monolayer makes the fabrication of advanced 2D optoelectronic devices in short wavelength possible. PMID- 29446429 TI - Optical nano-biosensing interface via nucleic acid amplification strategy: construction and application. AB - Modern optical detection technology plays a critical role in current clinical detection due to its high sensitivity and accuracy. However, higher requirements such as extremely high detection sensitivity have been put forward due to the clinical needs for the early finding and diagnosing of malignant tumors which are significant for tumor therapy. The technology of isothermal amplification with nucleic acids opens up avenues for meeting this requirement. Recent reports have shown that a nucleic acid amplification-assisted modern optical sensing interface has achieved satisfactory sensitivity and accuracy, high speed and specificity. Compared with isothermal amplification technology designed to work completely in a solution system, solid biosensing interfaces demonstrated better performances in stability and sensitivity due to their ease of separation from the reaction mixture and the better signal transduction on these optical nano-biosensing interfaces. Also the flexibility and designability during the construction of these nano-biosensing interfaces provided a promising research topic for the ultrasensitive detection of cancer diseases. In this review, we describe the construction of the burgeoning number of optical nano-biosensing interfaces assisted by a nucleic acid amplification strategy, and provide insightful views on: (1) approaches to the smart fabrication of an optical nano-biosensing interface, (2) biosensing mechanisms via the nucleic acid amplification method, (3) the newest strategies and future perspectives. PMID- 29446430 TI - Highly stable SnO2-Fe2O3-C hollow spheres for reversible lithium storage with extremely long cycle life. AB - SnO2-Fe2O3-C triple-shell hollow nano-spheres are fabricated by combining the template-based sol-gel coating technique and hydrothermal method, and their electrochemical performance as an anode for lithium ion batteries (LIBs) is investigated, particularly focusing on their structural stability and long term cyclability. To accomplish this, same-sized SnO2 solid spheres, Fe2O3 solid spheres, SnO2-Fe2O3 solid spheres, SnO2-Fe2O3-C solid spheres, SnO2 hollow spheres and SnO2-Fe2O3 hollow spheres are prepared in a similar manner and their cyclic performances are compared. It is found that the as-synthesized 80 nm-sized SnO2-Fe2O3-C hollow sphere electrode exhibits an extraordinary reversible capacity (1100 mA h g-1 after 100 cycles at 200 mA g-1) and excellent long cycle stability (475 mA h g-1 after 1000 cycles at 2000 mA g-1), which are attributed to the Fe-enhanced reversibility of the Li2O reduction reaction, high electrical conductivity, high Li+ ion mobility, and structural stability of the carbon coated triple-shell hollow spheres.

AB - Herein, a copper-catalyzed highly diastereoselective aerobic oxygenated [3+3] cyclization of 3-substituted indoles with C,N-cyclic azomethine imines using oxygen as the sole oxidant under mild conditions has been developed. This protocol provides a simple and convenient approach for constructing [2,3]-fused indoline O-heterocycles bearing two pharmaceutically intriguing parts, tetrahydroisoquinoline and indoline. Good yields and excellent diastereoselectivity under mild reaction conditions were observed. PMID- 29446432 TI - Serum albumin hydrogels in broad pH and temperature ranges: characterization of their self-assembled structures and nanoscopic and macroscopic properties. AB - We report extended pH- and temperature-induced preparation procedures and explore the materials and molecular properties of different types of hydrogels made from human and bovine serum albumin, the major transport protein in the blood of mammals. We describe the diverse range of properties of these hydrogels at three levels: (1) their viscoelastic (macroscopic) behavior, (2) protein secondary structure changes during the gelation process (via ATR-FTIR spectroscopy), and (3) the hydrogel fatty acid (FA) binding capacity and derive from this the generalized tertiary structure through CW EPR spectroscopy. We describe the possibility of preparing hydrogels from serum albumin under mild conditions such as low temperatures (notably below albumin's denaturation temperature) and neutral pH value. As such, the proteins retain most of their native secondary structure. We find that all the combined data indicate a two-stage gelation process that is studied in detail. We summarize these findings and the explored dependences of the gels on pH, temperature, concentration, and incubation time by proposing phase diagrams for both HSA and BSA gel-states. As such, it has become possible to prepare gels that have the desired nanoscopic and macroscopic properties, which can, in future, be tested for, e.g., drug delivery applications.

AB - An efficient asymmetric synthesis of trans-4,5-disubstituted gamma-butyrolactones from aldehydes and enantioenriched gamma-carbamate alkenylboronates is reported. The cornerstone of this strategy is the implementation of sequential [3,3]-allyl cyanate rearrangement/allylboration/nucleophilic addition/cyclisation reactions. Diverse gamma-butyrolactones such as the flavouring compounds, (+)-trans-whiskey lactone and (+)-trans-cognac lactone, as well as an advanced intermediate towards the first synthesis of natural products, (-)-nicotlactone B and (-)-galbacin, have thus been obtained. PMID- 29446434 TI - Thermal conversion of primary alcohols to disulfides via xanthate intermediates: an extension to the Chugaev elimination. AB - Primary alcohols are converted into dialkyl disulfides via heating in situ generated O-alkyl S-difluoro(ethoxycarbonyl)methyl xanthates from ethyl bromodifluoroacetate and potassium xanthates, prepared from primary alcohols and carbon disulfide in the presence of KOH. The reaction mechanism is suggested as an alkyl C[1,3] shift followed by a radical mechanism. This extends to the Chugaev elimination which yields olefins. The current research provides easy access to dialkyl disulfides from commercially available primary alkanols.

Flexible pseudo-crown ethers with aromatic donor/acceptor groups at the chain ends, however, displayed enhanced binding affinity and selectivity, particularly when the direct binding interactions were compromised by unfavorable solvents. PMID- 29446436 TI - The WITS Atlas: A Black Southern African dental atlas for permanent tooth formation and emergence. AB - : Current dental maturity charts, such as the widely applied London atlas, do not take into consideration advanced tooth emergence and formation patterns observed in children of African ancestry. The result is inaccurate age estimation in Southern Africa, a region where there is great forensic and anthropological need for reliable age estimation. OBJECTIVES: To develop a population-specific atlas of permanent tooth emergence and formation for age estimation of Black Southern Africans. MATERIALS AND METHODS: Using data from a cross-sectional study of 642 school children aged 5-20 years, panoramic radiographs taken during routine dental examination in a mobile treatment van were analyzed using the Demirjian method of eight (A-H) tooth formation stages. Tables of the stages of tooth development for each tooth, including the third molars, were generated separately for age cohorts and by sex. The most frequently occurring (modal) stage of tooth formation was considered the signature developmental stage for the age. The relationship of the third molar occlusal surfaces with occlusal tables on the radiographs were checked and compared with the findings recorded during intra oral examination. RESULTS: Comparison with the London atlas shows that at age 9.5 years, the canine and premolar emergence are at least one year ahead and the third molar formation completes four years earlier in the WITS Atlas. DISCUSSION: Similarities in advancement in tooth formation and emergence across sub-Saharan Africa suggest that the WITS Atlas can be used for those populations as well. PMID- 29446437 TI - Effects of total fat intake on bodyweight in children. AB - BACKGROUND: As part of efforts to prevent childhood overweight and obesity, we need to understand the relationship between total fat intake and body fatness in generally healthy children. OBJECTIVES: To assess the effects of total fat intake on measures of weight and body fatness in children and young people not aiming to lose weight. SEARCH METHODS: For this update we revised the previous search strategy and ran it over all years in the Cochrane Library, MEDLINE (Ovid), MEDLINE (PubMed), and Embase (Ovid) (current to 23 May 2017). No language and publication status limits were applied. We searched the World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov for ongoing and unpublished studies (5 June 2017). SELECTION CRITERIA: We included randomised controlled trials (RCTs) in children aged 24 months to 18 years, with or without risk factors for cardiovascular disease, randomised to a lower fat (30% or less of total energy (TE)) versus usual or moderate-fat diet (greater than 30%TE), without the intention to reduce weight, and assessed a measure of weight or body fatness after at least six months. We included prospective analytical cohort studies in these children if they related baseline total fat intake to weight or body fatness at least 12 months later. We duplicated inclusion decisions and resolved disagreement by discussion with other authors. DATA COLLECTION AND ANALYSIS: We extracted data on participants, interventions or exposures, controls and outcomes, and trial or cohort quality characteristics, as well as data on potential effect modifiers, and assessed risk of bias for all included studies. We extracted outcome data using the following time point ranges, when available: RCTs: baseline to six months, six to 12 months, one to two years, two to five years and more than five years; cohort studies: baseline to one year, one to two years, two to five years, five to 10 years and more than 10 years. We planned to perform random-effects meta-analyses with relevant subgrouping, and sensitivity and funnel plot analyses where data allowed. MAIN RESULTS: We included 24 studies comprising three parallel-group RCTs (n = 1054 randomised) and 21 prospective analytical cohort studies (about 25,059 children completed). Twenty-three were conducted in high-income countries. No meta analyses were possible, since only one RCT reported the same outcome at each time point range for all outcomes, and cohort studies were too heterogeneous.For the RCTs, concerns about imprecision and poor reporting limited our confidence in our findings. In addition, the inclusion of hypercholesteraemic children in two trials raised concerns about applicability. Lower versus usual or modified total fat intake may have made little or no difference to weight over a six- to twelve month period (mean difference (MD) -0.50 kg, 95% confidence interval (CI) -1.78 to 0.78; 1 RCT; n = 620; low-quality evidence), nor a two- to five-year period (MD -0.60 kg, 95% CI -2.39 to 1.19; 1 RCT; n = 612; low-quality evidence). Compared to controls, lower total fat intake (30% or less TE) probably decreased BMI in children over a one- to two-year period (MD -1.5 kg/m2, 95% CI -2.45 to 0.55; 1 RCT; n = 191; moderate-quality evidence), with no other differences evident across the other time points (two to five years: MD 0.00 kg/m2, 95% CI 0.63 to 0.63; 1 RCT; n = 541; greater than five years; MD -0.10 kg/m2, 95% CI 0.75 to 0.55; 1 RCT; n = 576; low-quality evidence). Lower fat intake probably slightly reduced total cholesterol over six to 12 months compared to controls (MD -0.15 mmol/L, 95% CI -0.24 to -0.06; 1 RCT; n = 618; moderate-quality evidence), but may make little or no difference over longer time periods. Lower fat intake probably slightly decreased low-density lipoprotein (LDL) cholesterol over six to 12 months (MD -0.12 mmol/L, 95% CI -0.20 to -0.04; 1 RCT; n = 618, moderate quality evidence) and over two to five years (MD -0.09, 95% CI -0.17 to -0.01; 1 RCT; n = 623; moderate-quality evidence), compared to controls. However, lower total fat intake probably made little or no difference to HDL-C over a six- to 12 month period (MD -0.03 mmol/L, 95% CI -0.08 to 0.02; 1 RCT; n = 618; moderate quality evidence), nor a two- to five-year period (MD -0.01 mmol/L, 95% CI -0.06 to 0.04; 1 RCT; n = 522; moderate-quality evidence). Likewise, lower total fat intake probably made little or no difference to triglycerides in children over a six- to 12-month period (MD -0.01 mmol/L, 95% CI -0.08 to 0.06; 1 RCT; n = 618; moderate-quality evidence). Lower versus usual or modified fat intake may make little or no difference to height over more than five years (MD -0.60 cm, 95% CI 2.06 to 0.86; 1 RCT; n = 577; low-quality evidence).Over half the cohort analyses that reported on primary outcomes suggested that as total fat intake increases, body fatness measures may move in the same direction. However, heterogeneous methods and reporting across cohort studies, and predominantly very low-quality evidence, made it difficult to draw firm conclusions and true relationships may be substantially different. AUTHORS' CONCLUSIONS: We were unable to reach firm conclusions. Limited evidence from three trials that randomised children to a lower total fat intake (30% or less TE) versus usual or modified fat intake, but with no intention to reduce weight, showed small reductions in body mass index, total- and LDL-cholesterol at some time points with lower fat intake compared to controls, and no consistent differences in effects on weight, high-density lipoprotein (HDL) cholesterol or height. Associations in cohort studies that related total fat intake to later measures of body fatness in children were inconsistent and the quality of this evidence was mostly very low. Twenty-three out of 24 included studies were conducted in high-income countries, and may not be applicable in low- and middle-income settings. High-quality, longer-term studies are needed, that include low- and middle-income settings and look at both possible benefits and risks. PMID- 29446438 TI - Three-dimensional (3D) geometric morphometric analysis of human premolars to assess sexual dimorphism and biological ancestry in Australian populations. AB - OBJECTIVES: This study aimed to investigate size and shape variation of human premolars between Indigenous Australians and Australians of European ancestry, and to assess whether sex and ancestry could be differentiated between these groups using 3D geometric morphometrics. MATERIALS AND METHODS: Seventy dental casts from each group, equally subdivided by sex, were scanned using a structured light scanner. The 3D meshes of upper and lower premolars were processed using geometric morphometric methods. Seventy-two landmarks were recorded for upper premolars and 50 landmarks for lower premolars. For each tooth type, two-way ANOVA was used to assess group differences in centroid size. Shape variations were explored using principal component analysis and visualized using 3D morphing. Two-way Procrustes ANOVA was applied to test group differences for ancestry and sex, and a "leave-one-out" discriminant function was applied to assess group assignment. RESULTS: Centroid size and shape did not display significant difference between the sexes. Centroid size was larger in Indigenous Australians for upper premolars and lower second premolars compared to the Australians of European ancestry. Significant shape variation was noted between the two ancestral groups for upper premolars and the lower first premolar. Correct group assignment of individual teeth to their ancestral groups ranged between 80.0 and 92.8% for upper premolars and 60.0 and 75.7% for lower premolars. DISCUSSION: Our findings provide evidence of significant size and shape variation in human premolars between the two ancestral groups. High classification rates based on shape analysis of upper premolars highlight potential application of geometric morphometrics in anthropological, bioarcheological and forensic contexts. PMID- 29446439 TI - Vision screening for correctable visual acuity deficits in school-age children and adolescents. AB - BACKGROUND: Although the benefits of vision screening seem intuitive, the value of such programmes in junior and senior schools has been questioned. In addition there exists a lack of clarity regarding the optimum age for screening and frequency at which to carry out screening. OBJECTIVES: To evaluate the effectiveness of vision screening programmes carried out in schools to reduce the prevalence of correctable visual acuity deficits due to refractive error in school-age children. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2017, Issue 4); Ovid MEDLINE; Ovid Embase; the ISRCTN registry; ClinicalTrials.gov and the ICTRP. The date of the search was 3 May 2017. SELECTION CRITERIA: We included randomised controlled trials (RCTs), including cluster-randomised trials, that compared vision screening with no vision screening, or compared interventions to improve uptake of spectacles or efficiency of vision screening. DATA COLLECTION AND ANALYSIS: Two review authors independently screened search results and extracted data. Our pre-specified primary outcome was uncorrected, or suboptimally corrected, visual acuity deficit due to refractive error six months after screening. Pre-specified secondary outcomes included visual acuity deficit due to refractive error more than six months after screening, visual acuity deficit due to causes other than refractive error, spectacle wearing, quality of life, costs, and adverse effects. We graded the certainty of the evidence using GRADE. MAIN RESULTS: We identified seven relevant studies. Five of these studies were conducted in China with one study in India and one in Tanzania. A total of 9858 children aged between 10 and 18 years were randomised in these studies, 8240 of whom (84%) were followed up between one and eight months after screening. Overall we judged the studies to be at low risk of bias. None of these studies compared vision screening for correctable visual acuity deficits with not screening.Two studies compared vision screening with the provision of free spectacles versus vision screening with no provision of free spectacles (prescription only). These studies provide high-certainty evidence that vision screening with provision of free spectacles results in a higher proportion of children wearing spectacles than if vision screening is accompanied by provision of a prescription only (risk ratio (RR) 1.60, 95% confidence interval (CI) 1.34 to 1.90; 1092 participants). The studies suggest that if approximately 250 per 1000 children given vision screening plus prescription only are wearing spectacles at follow-up (three to six months) then 400 per 1000 (335 to 475) children would be wearing spectacles after vision screening and provision of free spectacles. Low-certainty evidence suggested better educational attainment in children in the free spectacles group (adjusted difference 0.11 in standardised mathematics score, 95% CI 0.01 to 0.21, 1 study, 2289 participants). Costs were reported in one study in Tanzania in 2008 and indicated a relatively low cost of screening and spectacle provision (low-certainty evidence). There was no evidence of any important effect of provision of free spectacles on uncorrected visual acuity (mean difference -0.02 logMAR (95% CI adjusted for clustering -0.04 to 0.01) between the groups at follow-up (moderate-certainty evidence). Other pre-specified outcomes of this review were not reported.Two studies explored the effect of an educational intervention in addition to vision screening on spectacle wear. There was moderate-certainty evidence of little apparent effect of the education interventions investigated in these studies in addition to vision screening, compared to vision screening alone for spectacle wearing (RR 1.11, 95% CI 0.95 to 1.31, 1 study, 3177 participants) or related outcome spectacle purchase (odds ratio (OR) 0.84, 95% CI 0.55 to 1.31, 1 study, 4448 participants). Other pre-specified outcomes of this review were not reported.Three studies compared vision screening with ready-made spectacles versus vision screening with custom-made spectacles. These studies provide moderate-certainty evidence of no clinically meaningful differences between the two types of spectacles. In one study, mean logMAR acuity in better and worse eye was similar between groups: mean difference (MD) better eye 0.03 logMAR, 95% CI 0.01 to 0.05; 414 participants; MD worse eye 0.06 logMAR, 95% CI 0.04 to 0.08; 414 participants). There was high-certainty evidence of no important difference in spectacle wearing (RR 0.98, 95% CI 0.91 to 1.05; 1203 participants) between the two groups and moderate-certainty evidence of no important difference in quality of life between the two groups (the mean quality-of-life score measured using the National Eye Institute Refractive Error Quality of Life scale 42 was 1.42 better (1.04 worse to 3.90 better) in children with ready-made spectacles (1 study of 188 participants). Although none of the studies reported on costs directly, ready-made spectacles are cheaper and may represent considerable cost savings for vision screening programmes in lower income settings. There was low certainty evidence of no important difference in adverse effects between the two groups. Adverse effects were reported in one study and were similar between groups. These included blurred vision, distorted vision, headache, disorientation, dizziness, eyestrain and nausea. AUTHORS' CONCLUSIONS: Vision screening plus provision of free spectacles improves the number of children who have and wear the spectacles they need compared with providing a prescription only. This may lead to better educational outcomes. Health education interventions, as currently devised and tested, do not appear to improve spectacle wearing in children. In lower-income settings, ready-made spectacles may provide a useful alternative to expensive custom-made spectacles. PMID- 29446440 TI - Mechanical implications of the mandibular coronoid process morphology in Neandertals. AB - OBJECTIVES: Among the diagnostic features of the Neandertal mandible are the broad base of the coronoid process and its straight posterior margin. The adaptive value of these (and other) anatomical features has been linked to the Neandertal's need to cope with a large gape. The present study aims to test this hypothesis with regard to the morphology of the coronoid process. MATERIALS AND METHODS: This admittedly simple, intuitive hypothesis was tested here via a comparative finite-element study of the primitive versus modified state of the coronoid process, using two-dimensional models of the mandible. RESULTS: Our simulations demonstrate that a large gape has an unfavorable effect on the primitive state of the coronoid process: the diagonal, almost horizontal, component of the temporalis muscle resultant (relative to the long axis of the coronoid process) bends the process in the sagittal plane. Furthermore, we show that the modification of the coronoid process morphology alone reduces the process' bending in a wide gape increasing the compression to tension ratio. DISCUSSION: These results provide indirect evidence in support of the hypothesis that the modification of the coronoid process in Neandertals is necessary for enabling their mandible to cope with a large gape. PMID- 29446441 TI - OsPIN2, which encodes a member of the auxin efflux carrier proteins, is involved in root elongation growth and lateral root formation patterns via the regulation of auxin distribution in rice. AB - Auxin flow is important for different root developmental processes such as root formation, emergence, elongation and gravitropism. However, the detailed information about the mechanisms regulating the auxin flow is less well understood in rice. We characterized the auxin transport-related mutants, Ospin formed2-1 (Ospin2-1) and Ospin2-2, which exhibited curly root phenotypes and altered lateral root formation patterns in rice. The OsPIN2 gene encodes a member of the auxin efflux carrier proteins that possibly regulates the basipetal auxin flow from the root tip toward the root elongation zone. According to DR5-driven GUS expression, there is an asymmetric auxin distribution in the mutants that corresponded with the asymmetric cell elongation pattern in the mutant root tip. Auxin transport inhibitor, N-1-naphthylphthalamic acid and Ospin2-1 Osiaa13 double mutant rescued the curly root phenotype indicating that this phenotype results from a defect in proper auxin distribution. The typical curly root phenotype was not observed when Ospin2-1 was grown in distilled water as an alternative to tap water, although higher auxin levels were found at the root tip region of the mutant than that of the wild-type. Therefore, the lateral root formation zone in the mutant was shifted basipetally compared with the wild-type. These results reflect that an altered auxin flow in the root tip region is responsible for root elongation growth and lateral root formation patterns in rice.

AB - BACKGROUND: Influenza immune globulin, manufactured from plasma of convalescent or vaccinated donors has been proposed as a potential therapy for severe influenza. In 2009, a program was initiated to collect plasma from donors who self-identified as having had H1N1 influenza or having received the H1N1 pandemic vaccine. The goal of this study was to determine the efficiency of donor screening by self-identification without antibody testing, and to evaluate demographic predictors of high-titer donations. STUDY DESIGN AND METHODS: Plasma samples from self-identified or control donors were randomly selected to evaluate hemagglutination inhibition (HAI) antibody responses. HAI titers were correlated with donor age, gender, location, and influenza exposure history. RESULTS: Both self-identified vaccinated and convalescent donor groups had higher geometric mean titers (GMTs) against A/California/07/2009 (H1N1) virus compared to the control donors (39.9, 24, and 8.5, respectively). The proportion of samples with titers >=64 in vaccinated, convalescent, and control donors were 54%, 37%, and 10%, respectively. Donations with titers <=16 were predominant in control donors (80%) and substantial in convalescent (47%) and vaccinated (40%) donors. Titers did not correlate with donor age, gender, or geographical location. GMTs for vaccinated donors were significantly higher than for convalescent donors and in both groups significantly higher than in the control. CONCLUSION: Targeted collection of plasma containing high levels of anti-influenza antibodies from self-identified donors was effective, but could be further improved by reducing the number of low-titer donations. More selective donor screening and/or testing for influenza antibodies could increase the potency of an influenza antibody-rich immune globulin (FLUIGIV). PMID- 29446443 TI - Association of killer cell immunoglobulin-like receptors with spontaneous clearance of hepatitis C virus in the Chinese population. AB - BACKGROUND: Natural killer (NK) cells are critical components in innate immune response to viral infection. Killer cell immunoglobulin-like receptors (KIRs) are involved in regulating the balance of activation or inhibitory function of NK cells. However, the association of KIRs with the spontaneous clearance of hepatitis C virus (HCV) remains unclear in the Chinese population. STUDY DESIGN AND METHODS: A total of 407 HCV-seropositive voluntary blood donors were recruited, including 203 with spontaneous viral clearance and 204 with chronic infection. The presence of KIR genes was detected individually by polymerase chain reaction with sequence-specific primers. Data of HLA and interleukin-28B (IL28B) genotypes were extracted from our previous study. RESULTS: Our results showed that KIR2DL2, 2DS2, 2DL2/2DL3, and 2DL5A-/2DL5B+ were more frequent in subjects with HCV clearance than those with chronic infection (odds ratio [OR], 1.640, p = 0.034; OR, 1.664, p = 0.032; OR, 1.636, p = 0.040; and OR, 2.601, p = 0.012, respectively). Multivariate logistic regression analysis showed that KIR2DL5A-/2DL5B+ associated with HCV clearance (OR, 2.448, p = 0.027), independent of sex, IL28B, and other KIRs. In contrast, KIR2DL3/2DL3 (OR, 0.610, p = 0.034) as well as 2DL3/2DL3+HLA-C1 or C1C1 (OR, 0.580, p = 0.017; and OR, 0.639, p = 0.025, respectively) was found associated with chronic HCV infection. The presence of the homozygous KIR2DL3 with or without its HLA ligand increased the OR of developing chronic HCV infection in the context of IL28B. CONCLUSIONS: In this study we identified KIR2DL5A-/2DL5B+ associated with HCV spontaneous clearance, while KIR2DL3/2DL3, 2DL3/2DL3+HLA-C1, or C1C1 associated with chronic infection. Our study highlighted the fact that the roles of KIR and KIR-HLA contributed to the control of HCV infection by innate immune responses. PMID- 29446445 TI - Lenograstim 5 ug/kg is not superior to biosimilar filgrastim 10 ug/kg in lymphoma patients undergoing peripheral blood stem cell mobilization after chemotherapy: preliminary results from a prospective randomized study. AB - BACKGROUND: Randomized trials comparing chemomobilization efficiency between lenograstim and biosimilar filgrastim are lacking. Our previous retrospective study suggested that lenograstim could be more effective than biosimilar filgrastim when used at the same conventional dosage (5 ug/kg) only in lymphoma patients undergoing peripheral blood stem cell mobilization. We planned a prospective randomized study comparing lenograstim 5 ug/kg with biosimilar filgrastim 10 ug/kg to verify the hypothesis of lenograstim superiority even at half the dosage (stress test). Herein we report data after enrolling 60% of planned patients. STUDY DESIGN AND METHODS: From October 2014 to November 2017, a total of 42 of 70 planned patients with lymphoma were randomly assigned to receive lenograstim 5 ug/kg (21) or biosimilar filgrastim 10 ug/kg (21). Patients were stratified according to treatment line at the time of mobilization (1 or >=2). Primary endpoint was the rate of achievement of the CD34+ cell collection target dose (>= 4 * 106 /kg). An improvement by 23% was expected to validate the hypothesis of lenograstim superiority. RESULTS: The two cohorts were balanced for all the baseline features. We observed an identical rate of patients able to reach the targeted CD34+ cell dose and of mobilization failures (90.4 and 4.8% in both cohorts) and a perfect equivalence in any of the secondary collection outcomes. The hypothesis of lenograstim superiority was not corroborated at interim analysis. CONCLUSION: Lenograstim at conventional dosage has failed to demonstrate its superiority over biosimilar filgrastim at double the dosage at interim analysis in their first head-to-head trial. PMID- 29446444 TI - Extracorporeal photopheresis as second-line therapy for patients with acute graft versus-host disease: does the number of cells treated matter? AB - BACKGROUND: Extracorporeal photopheresis (ECP) has demonstrated efficacy as second-line treatment for steroid-refractory (SR) acute graft-versus-host disease (aGVHD). The aim of our study was to analyze whether the amount of ECP-treated cells in patients with SR, aGVHD has an impact on response at 1 month. STUDY DESIGN AND METHODS: Data on white blood cells, lymphocytes, monocytes, mononuclear cells, and neutrophils, including absolute counts and counts per kilogram of body weight in ECP products from patients with aGVHD, were collected. For each cell population, the median dose per single ECP and the cumulative doses collected during the first week and the first month of treatment were compared with the response to ECP. RESULTS: In total, 99 patients underwent 1215 ECP procedures. Overall response was defined as a complete response if all signs of aGVHD resolved or a partial response if greater than 50% resolution was reached without other, additional immunosuppression. An overall response was obtained by 75% of patients, including 53% complete responses. Univariate analysis showed a correlation of lymphocytes and mononuclear cells/kg body weight for a single procedure and overall response. In logistic regression analysis, no tested variable had an influence on response. In receiver operating characteristic curve analysis, cutoffs of 8.4 * 106 /kg body weight lymphocytes and 13.9 * 106 /kg body weight mononuclear cells were associated with an overall response to ECP at 1 month with 75% sensitivity. CONCLUSION: Our results in patients with steroid refractory aGVHD confirm that response rates to ECP are high and that certain cutoff values for lymphocytes and mononuclear cells/kg body weight in each individual procedure can predict an overall response to ECP at 1 month. PMID- 29446446 TI - Telemedicine in otolaryngology outpatient setting-single Center Head and Neck Surgery experience. AB - OBJECTIVES/HYPOTHESIS: We present our experience with telemedicine visits in an otolaryngology outpatient setting within our institution's Center for Head and Neck Surgery. STUDY DESIGN: Retrospective chart review. METHODS: A review of telemedicine outpatient encounters examining patient demographics, visit type, and wait times was conducted. Internet-based navigation applications were used to calculate travel distance and estimate commute time to our clinic. Patient survey responses were reviewed. RESULTS: Two hundred fifty telemedicine encounters were reviewed between December 2015 and June 2017. The average age of patients was 50 years (range, 4-87 years). Patients waited an average of 10 minutes for their telemedicine appointments and avoided an average estimated commute time of 78 minutes (64 miles). The majority of visits were postoperative encounters (70%). Clinical follow-up of recent results or nonpostoperative complaints accounted for the remaining 30% of visits. All patients were offered a post-telemedicine survey, and 78 (31%) completed the survey. Of the respondents, 95% of patients reported that they were satisfied with their visit. Among patients who were dissatisfied, wait time and technical issues were cited as reasons. CONCLUSIONS: With appropriate patient selection, telemedicine is an effective way to safely conduct outpatient clinic visits while maintaining high patient satisfaction. It can be particularly useful for institutions with large catchment areas to minimize travel times and increase ease of communication. LEVEL OF EVIDENCE: 4. Laryngoscope, 128:2072-2075, 2018.

AB - The objective of this study was to create a clinically useful tool for individualized prediction of seizure outcomes following antiepileptic drug withdrawal after pediatric epilepsy surgery. We used data from the European retrospective TimeToStop study, which included 766 children from 15 centers, to perform a proportional hazard regression analysis. The 2 outcome measures were seizure recurrence and seizure freedom in the last year of follow-up. Prognostic factors were identified through systematic review of the literature. The strongest predictors for each outcome were selected through backward selection, after which nomograms were created. The final models included 3 to 5 factors per model. Discrimination in terms of adjusted concordance statistic was 0.68 (95% confidence interval [CI] 0.67-0.69) for predicting seizure recurrence and 0.73 (95% CI 0.72-0.75) for predicting eventual seizure freedom. An online prediction tool is provided on www.epilepsypredictiontools.info/ttswithdrawal. The presented models can improve counseling of patients and parents regarding postoperative antiepileptic drug policies, by estimating individualized risks of seizure recurrence and eventual outcome. PMID- 29446449 TI - Opioid prescribing patterns among otolaryngologists: Crucial insights among the medicare population. AB - OBJECTIVES/HYPOTHESIS: There has been growing recognition of the roles prescription drug misuse and diversion play in facilitating the ongoing opioid epidemic. Our objective was to evaluate opioid prescription patterns among practicing otolaryngologists. STUDY DESIGN: Retrospective review of a CMS database. METHODS: Medicare Part D beneficiary data (2015) were accessed for a list of otolaryngologists. Opioid prescription rates, amount, and supply were calculated. Factors including board certification, experience, gender, and location were obtained for the 9,068 unique otolaryngologists represented in this dataset. RESULTS: In 2015, otolaryngologists wrote 133,779 opioid prescriptions for 922,806 days (6.9 days/per prescription). The majority was for hydrocodone acetaminophen (64.0%). Most otolaryngologists (51.2%) prescribed <= 10 opioids; 6.1% offered > 50 opioid prescriptions. Men wrote more prescriptions on average. Opioid prescription rates were greatest in the Midwest (4.6%) and least in the Northeast (1.8%), and the highest/lowest rates were in Delaware (8.6%) and New York (1.3%). Midcareer (11 -20 years) otolaryngologists were most likely to write >50 prescriptions. The opioid prescription rate declined with greater experience. CONCLUSIONS: Opioid prescriptions written by otolaryngologists may play a significant role in the availability of these agents, as otolaryngologists wrote nearly 1 million days worth of opioids to Medicare beneficiaries in 2015. Although the majority of otolaryngologists write fewer than 11 prescriptions annually, those writing more prescriptions also write lengthier courses. There is significant geographic variation in prescribing patterns, highlighting a lack of consensus, and midcareer otolaryngologists are more aggressive in offering opioids. These findings highlight an urgent need for strengthening educational resources aimed at minimizing unnecessary prescriptions. LEVEL OF EVIDENCE: NA. Laryngoscope, 128:1576-1581, 2018. PMID- 29446450 TI - Comparison of physical chewing measures to consumer typed Mouth Behavior. AB - : The purpose of this study was to investigate the hypotheses that when presented with foods that could be chewed in different ways, (1) are participants jaw movements and chewing sequence measures correlated with Mouth Behavior (MB) group, as measured by the JBMB typing tool? (2) can MB group membership can be predicted from jaw movement and chewing sequence measures? One hundred subjects (69 female and 31 male, mean age 27 +/- 7.7 years) were given four different foods (Mentos, Walkers, Cheetos Puffs, Twix) and video recordings of their jaw movements made. Twenty-nine parameters were calculated on each chewing sequence with 27 also calculated for the first half and second half of chewing sequence. Subjects were assigned to a MB group using the JBMB typing tool which gives four MB groups ("Chewers," "Crunchers," "Smooshers," and "Suckers"). The differences between individual chewing parameters and MB group were assessed with analysis of variance which showed only small differences in average chewing parameters between the MB groups. By using discriminant analysis, it was possible to partially discriminate between MB groups based on changes in their chewing parameters between foods with different material properties and stages of the chewing. A 19-variable model correctly predicted 68% of the subjects' membership of a MB group. This partially confirms our first hypothesis that when presented with foods that could be chewed in different ways participants will use a chewing sequence and jaw movements that correlate with their MB as measured by the JBMB typing tool. PRACTICAL APPLICATIONS: The way consumers chew their food has an impact on their texture perception of that food. While there is a wide range of chewing behaviors between consumers, they can be grouped into broad categories to better target both product design and product testing by sensory panel. In this study, consumers who were grouped on their texture preference (MB group) had jaw movements, when chewing a range of foods, which partially reflected group membership. Therefore, while MB group membership could not be predicted from jaw movement measurements, there were similarities in jaw movements within the members of the groups. A better understanding of how jaw movement during chewing relates to consumer sensory perception would aid in new solid product design with controlled textural attributes. PMID- 29446451 TI - Practical data collection and extraction for big data applications in radiotherapy. AB - The capture of high-quality treatment data and outcomes is necessary in order to learn from our clinical experiences with big data analytics. In radiotherapy, there are several practical challenges to overcome. Practical aspects of data collection are discussed pointing to a need for a culture change in clinical practice to one that captures structured patient-related data in routine care in a prospective manner. Radiation dosimetry and the contoured anatomy must also be captured routinely to represent the best estimate of delivered radiation. The quality and integrity present in the data are critical which poses opportunities to introduce electronic validity checking to improve them. Similarly, data completeness and methods and technology to improve the efficiency and sufficiency of data capture can be introduced. In the manuscript, the types of clinical data are discussed including patient reports, images, biospecimens, treatments, and symptom management. With a data-driven culture, the realization of a learning health system is possible unlocking the potential of big data and its influence on clinical decision-making and hypothesis generation. PMID- 29446452 TI - Development of Children's Use of External Reminders for Hard-to-Remember Intentions. AB - This study explored under what conditions young children would set reminders to aid their memory for delayed intentions. A computerized task requiring participants to carry out delayed intentions under varying levels of cognitive load was presented to 63 children (aged between 6.9 and 13.0 years old). Children of all ages demonstrated metacognitive predictions of their performance that were congruent with task difficulty. Only older children, however, set more reminders when they expected their future memory performance to be poorer. These results suggest that most primary school-aged children possess metacognitive knowledge about their prospective memory limits, but that only older children may be able to exercise the metacognitive control required to translate this knowledge into strategic reminder setting. PMID- 29446453 TI - A Semiempirical Approach to the Determination of Daily Erythemal Doses. AB - The maintenance of ground-based instruments to measure the incidence of ultraviolet radiation (UVR) from the Sun demands strict and well-developed procedures. A piece of equipment can be out of service for a couple of weeks or months for calibration, repair or even the improvement of the facilities where it has been set up. However, the replacement of an instrument in such circumstances can be logistically and financially prohibitive. On the other hand, the lack of data can jeopardize a long-term experiment. In this study, we introduce a semiempirical approach to the determination of the theoretical daily erythemal dose (DEDt ) for periods of instrumental absence in a tropical site. The approach is based on 5 years of ground-based measurements of daily erythemal dose (DED) linearly correlated with parameters of total ozone column (TOC) and reflectivity (RPC ) from the Ozone Monitoring Instrument (OMI) and the cosine of solar zenith angle at noon (SZAn ). Seventeen months of missing ground-based data were replaced with DEDt , leading to a complete 5-year series of data. The lowest and the highest values of typical DED were 2411 +/- 322 J m-2 (1sigma) (winter) and 5263 +/- 997 J m-2 (summer). The monthly integrated erythemal dose (mED) varied from 59 kJ m-2 (winter) to 162 kJ m-2 (summer). Both of them depended mainly on cos(SZAn ) and RPC . The 12-month integrated erythemal dose (12-ED) ranged from 1350 kJ m-2 to 1546 kJ m-2 , but it can depend significantly on other atmospheric parameter (maybe aerosols) not explicitly considered here.

PMID- 29446455 TI - Uncultivated stromal vascular fraction is equivalent to adipose-derived stem and stromal cells on porous polyurethrane scaffolds forming adipose tissue in vivo. AB - OBJECTIVES/HYPOTHESIS: To find an alternative approach to contemporary techniques in tissue augmentation and reconstruction, tissue engineering strategies aim to involve adipose-derived stem and stromal cells (ASCs) harboring a strong differentiation potential into various tissue types such as bone, cartilage, and fat. STUDY DESIGN: Animal research. METHODS: The stromal vascular fraction (SVF) was used directly as a cell source to provide a potential alternative to contemporary ASC-based adipose tissue engineering. Seeded in TissuCol fibrin, we applied ASCs or SVF cells to porous, degradable polyurethane (PU) scaffolds. RESULTS: We successfully demonstrated the in vivo generation of volume-stable, well-vascularized PU-based constructs containing host-derived mature fat pads. Seeded human stem cells served as modulators of host-cell migration rather than differentiating themselves. We further demonstrated that preliminary culture of SVF cells was not necessary. CONCLUSIONS: Our results bring adipose tissue engineering, together with automated processing devices, closer to clinical applicability. The time-consuming and cost-intensive culture and induction of the ASCs is not necessary. LEVEL OF EVIDENCE: NA. Laryngoscope, 128:E206-E213, 2018. PMID- 29446456 TI - Lack of mitochondrial thioredoxin o1 is compensated by antioxidant components under salinity in Arabidopsis thaliana plants. AB - In a changing environment, plants are able to acclimate to new conditions by regulating their metabolism through the antioxidant and redox systems involved in the stress response. Here, we studied a mitochondrial thioredoxin in wild-type (WT) Arabidopis thaliana and two Attrxo1 mutant lines grown in the absence or presence of 100 mM NaCl. Compared to WT plants, no evident phenotype was observed in the mutant plants under control condition, although they had higher number of stomata, loss of water, nitric oxide and carbonyl protein contents as well as higher activity of superoxide dismutase (SOD) and catalase enzymes than WT plants. Under salinity, the mutants presented lower water loss and higher stomatal closure, H2 O2 and lipid peroxidation levels accompanied by higher enzymatic activity of catalase and the different SOD isoenzymes compared to WT plants. These inductions may collaborate in the maintenance of plant integrity and growth observed under saline conditions, possibly as a way to compensate the lack of TRXo1. We discuss the potential of TRXo1 to influence the development of the whole plant under saline conditions, which have great value for the agronomy of plants growing under unfavorable environment. PMID- 29446457 TI - Toward a multifactorial model of expertise: beyond born versus made. AB - The debate over the origins of individual differences in expertise has raged for over a century in psychology. The "nature" view holds that expertise reflects "innate talent"-that is, genetically determined abilities. The "nurture" view counters that, if talent even exists, its effects on ultimate performance are negligible. While no scientist takes seriously a strict nature-only view of expertise, the nurture view has gained tremendous popularity over the past several decades. This environmentalist view holds that individual differences in expertise reflect training history, with no important contribution to ultimate performance by innate ability ("talent"). Here, we argue that, despite its popularity, this view is inadequate to account for the evidence concerning the origins of expertise that has accumulated since the view was first proposed. More generally, we argue that the nature versus nurture debate in research on expertise is over-or certainly should be, as it has been in other areas of psychological research for decades. We describe a multifactorial model for research on the nature and nurture of expertise, which we believe will provide a progressive direction for future research on expertise. PMID- 29446458 TI - Clinical criteria for CT scan evaluation of upper digestive tract fishbone. AB - OBJECTIVES: To establish clinical criteria for performing computed tomography scan for suspected upper digestive tract fishbone. METHODS: This is a prospective study of all adult patients referred to the otolaryngology emergency department at our medical center for suspected fishbone in the upper digestive tract after no fishbone was seen on physical examination. The patients were divided into two groups: 1) The first was a high clinical suspicion group, which included patients with at least one of the following criteria: drooling, accumulation of saliva in the sinus piriformis, fever, referral 24 hours after the ingestion with worsening/continuing symptoms, and readmission. These patients underwent nonenhanced CT scan (NECT) of the neck. 2) The second was a low clinical suspicion group, which included patients discharged with no NECT performed. These patients were followed at 1 week and 3 months. RESULTS: One hundred and fourteen patients were included in the study; the median age was 41 years. Half of the patients arrived at the emergency department within 7 hours. There were no false negatives. The negative predictive value and sensitivity were 100%. Positive predictive value and specificity were 28.5% and 65%, respectively. Referral to the emergency department 24 hours after the ingestion with continuing symptoms had the highest false positive rate. CONCLUSIONS: Our clinical criteria score for excluding foreign body fishbone in the upper aerodigestive tract was established. According to this score, a NECT can be spared in about 75% of all cases, thus reducing unnecessary ionizing radiation, stay at the emergency department, and costs with a very high NPV of almost 99%.

AB - OBJECTIVES: To infer the ecogeographic conditions that underlie the evolutionary diversification of macaques, we investigated the within- and between-species relationships of craniodental dimensions, geography, and environment in extant macaque species. We studied evolutionary processes by contrasting macroevolutionary patterns, phylogeny, and within-species associations. MATERIALS AND METHODS: Sixty-three linear measurements of the permanent dentition and skull along with data about climate, ecology (environment), and spatial geography were collected for 711 specimens of 12 macaque species and analyzed by a multivariate approach. Phylogenetic two-block partial least squares was used to identify patterns of covariance between craniodental and environmental variation. Phylogenetic reduced rank regression was employed to analyze spatial clines in morphological variation. RESULTS: Between-species associations consisted of two distinct multivariate patterns. The first represents overall craniodental size and is negatively associated with temperature and habitat, but positively with latitude. The second pattern shows an antero-posterior tooth size contrast related to diet, rainfall, and habitat productivity. After controlling for phylogeny, however, the latter dimension was diminished. Within-species analyses neither revealed significant association between morphology, environment, and geography, nor evidence of isolation by distance. DISCUSSION: We found evidence for environmental adaptation in macaque body and craniodental size, primarily driven by selection for thermoregulation. This pattern cannot be explained by the within-species pattern, indicating an evolved genetic basis for the between species relationship. The dietary signal in relative tooth size, by contrast, can largely be explained by phylogeny. This cautions against adaptive interpretations of phenotype-environment associations when phylogeny is not explicitly modelled.

PMID- 29446459 TI - The challenge of converting Gram-positive-only compounds into broad-spectrum antibiotics. AB - Multidrug resistant Gram-negative bacterial infections are on the rise, and there is a lack of new classes of drugs to treat these pathogens. This drug shortage is largely due to the challenge of finding antibiotics that can permeate and persist inside Gram-negative species. Efforts to understand the molecular properties that enable certain compounds to accumulate in Gram-negative bacteria based on retrospective studies of known antibiotics have not been generally actionable in the development of new antibiotics. A recent assessment of the ability of >180 diverse small molecules to accumulate in Escherichia coli led to predictive guidelines for compound accumulation in E. coli. These "eNTRy rules" state that compounds are most likely to accumulate if they contain a nonsterically encumbered ionizable Nitrogen (primary amines are the best), have low Three dimensionality (globularity <= 0.25), and are relatively Rigid (rotatable bonds <= 5). In this review, we look back through 50+ years of antibacterial research and 1000s of derivatives and assess this historical data set through the lens of these predictive guidelines. The results are consistent with the eNTRy rules, suggesting that the eNTRy rules may provide an actionable and general roadmap for the conversion of Gram-positive-only compounds into broad-spectrum antibiotics.

PMID- 29446461 TI - A method for red blood cell biotinylation in a closed system. AB - BACKGROUND: Several circumstances require the accurate measurement of red blood cell (RBC) survival and clearance, such as determination of posttransfusion recovery of stored RBCs to investigate the effect of new additive solutions. To this end, biotin as a marker of RBCs to track donor RBCs in the blood of the recipient has been used in many studies. However, so far only experimental, nonvalidated, biotin-labeled red cell concentrates (RCCs) are transfused. The goal of this study was to produce a standardized biotin-labeled RCC product in a fast, simple, and sterile manner that can be used for clinical research and for the evaluation of new blood products according to Good Practice Guidelines (GPG) for blood establishments. STUDY DESIGN AND METHODS: RCC fractions were labeled with two different concentrations of biotinylation reagent in a closed system, to prevent bacterial contamination of the end product. Using flow cytometry, the reproducibility and robustness of the biotin labeling was assessed, as well as the stability of the biotin label on the (un-)irradiated RCC fraction. Additionally, parameters such as phosphatidylserine (PS) exposure, sodium (Na), potassium (K), free hemoglobin, adenosine triphosphate (ATP), pH, and morphology were determined prior to and after biotin labeling to rule out detrimental effects of the labeling procedure on the RCC. RESULTS: Our data show that RCCs can be labeled under sterile conditions in a closed system with two different biotinylation reagent concentrations, without affecting the biological activity. CONCLUSION: An easy, rapid (<2 hr), and robust method was developed to manufacture biotin-labeled RCCs for clinical research compliant to GPG.

AB - OBJECTIVES: Although integration studies are important to understand the evolution of organisms' traits across phylogenies, vertebral integration in primates is still largely unexplored. Here we describe and quantify patterns of morphological integration and modularity in the subaxial cervical vertebrae (C3 C7) in extant hominines incorporating the potential influence of size. MATERIALS AND METHODS: Three-dimensional landmarks were digitized on 546 subaxial cervical vertebrae from 141 adult individuals of Gorilla gorilla, Pan troglodytes, and Homo sapiens. Integration and modularity, and the influence of size effects, were quantified using geometric morphometric approaches. RESULTS: All subaxial cervical vertebrae from the three species show a strong degree of integration. Gorillas show the highest degree of integration; conversely, humans have the lowest degree of integration. Analyses of allometric regression residuals show that size is an important factor promoting integration in gorillas, with lesser influence in chimpanzees and almost no effect in humans. DISCUSSION: Results point to a likely ancestral pattern of integration in non-human hominines, whereby the degree of integration decreases from cranial to caudal positions. Humans deviate from this pattern in the cranialmost (C3) and, to a lesser extent, in the caudalmost (C7) vertebrae, which are less integrated. These differences can be tentatively related to the emergence of bipedalism due to the presence of modern human-like C3 in australopiths, which still preserve a more chimpanzee like C7.

AB - In the present study, we evaluated the prevalence of occult hepatitis B (OBI) in a population from the Brazilian Amazon region, identify circulating genotypes, and mutations in the S gene. One hundred eighty-one patients with negative serology for HBsAg and anti-HBs and positive serology for anti-HBc participated in the study. Detection of viral DNA, genotyping by sequencing, and analysis of nucleotide sequences to detect possible mutations were performed. HBV DNA was detected in 14.36% of the patients. Genotyping revealed genotype A in 88.46% of HBV DNA-positive subjects, with subgenotype A1 being the most prevalent (78.26%) followed by subgenotype A2 (21.74%). Genotype F was detected in 11.54% (all of them subgenotype F2). Amino acid substitutions were observed in the amplified S gene in individuals with OBI compared to HBsAg-positive individuals (evident infection). In conclusion, the results show a high prevalence of OBI in the population studied, with a pattern of genotypes A and F that circulate in the Brazilian Amazon region. Amino acid substitutions were detected in part of the S gene in patients with OBI. Further studies on the molecular epidemiology of HBV in this region are important to identify patients considered healthy but who are potential transmitters of the disease. PMID- 29446469 TI - Clinical trials in allergen immunotherapy: current concepts and future needs. AB - Allergen immunotherapy (AIT) is a safe, effective treatment for allergic rhinoconjunctivitis and allergic asthma. However, AIT's clinical effect is still contested-primarily due to heterogeneity in clinical trial designs, study populations, therapeutic formulations, and efficacy criteria. After discussing current concepts and unmet needs, an international panel of experts made several recommendations: (i) explore and validate definitions for (clinical) responders in AIT trials; (ii) use of well-documented, standardized provocation tests prior to inclusion of subjects with relevant diseases in AIT trials; (iii) monitoring neo-sensitizations and occurrence of new allergy in extended AIT trials, and exclusion of polyallergic participants; (iv) validation of allergen exposure chambers with regard to natural exposure; (v) in studies of seasonal allergies, focus on peak exposure but also consider organizing two parallel, geographically distinct but otherwise identical trials; (vi) discuss adaptive trial designs with the regulatory authorities; (vii) use e-health and m-health technologies to capture more information on individual exposure to allergens; (viii) initiate research on potential psychological, biochemical, immune, neural, and even genomic markers of the placebo response; (ix) identify trial designs and primary endpoints that will give children with allergies easier, faster access to AIT formulations; and (x) promote and apply standardized methods for reporting systemic and local adverse events. The latest technologies and trial designs may provide novel, ethical ways of reducing bias and heterogeneity in AIT clinical trials. There is scope for physicians, patient organizations, companies, and regulators to improve clinical trials in AIT and, ultimately, to provide patients with better treatments. PMID- 29446470 TI - HEV and HAV seroprevalence in men that have sex with men (MSM): An update from Milan, Italy. AB - Hepatitis E virus (HEV) is a feco-orally transmitted pathogen and one of the most common cause of acute hepatitis worldwide. Recent studies in developed countries suggested that a direct human-to-human contact such as for sexually transmitted diseases may play a significant role in the HEV spread. The aim of this study was to investigate the seroprevalence of HEV and HAV in a group of MSM, including subjects HIV, and Treponema infected, in Milan, Italy. The overall anti HEV IgG seroprevalence in MSM was 10.2% (65/636), instead in the control group the detection rate was 5.2% (15/288) (P < 0.05); the anti HAV seroprevalence was 42.8% in MSM, when in the control group the positivity rate was 29.2% (P < 0.05). The rate of coinfection HEV/HAV was 14.6% in MSM and 1% in control group (P < 0.05). In the future, sexual history, HIV status, and STI risk might address specific investigations to prevent spread of pathogens such HEV in MSM, before becoming a substantial public health problem like for HAV outbreaks.

AB - To clinically evaluate the patient satisfaction and associated costs of dentures made using a simplified procedure that eliminates assembly on the articulator and dentures made with the conventional technique. Single-blind randomised clinical trial. Forty edentulous patients were randomly divided into 2 groups. One group received dentures made using the conventional method (CG), and the other using a simplified technique (SG) that omits the use of functional impressions (with modelling compound and ZOE impression paste) and an articulator to assemble the models. Overall patient satisfaction was assessed at 3 and 6 months by means of a Numerical Rating Scale (NRS). The comparisons were made using a repeated measures ANOVA (P = .05). No significant differences were found in terms of the satisfaction stated by the patients or the quality of the prosthesis evaluated by a professional among the dentures made using the traditional (n = 17) and simplified (n = 21) techniques. The rehabilitation of an edentulous patient with a simplified technique for the preparation of a total prosthesis is a feasible, more economical alternative and accepted by most patients. PMID- 29446472 TI - Hantavirus induced cardiopulmonary syndrome: A public health concern. AB - Hantavirus cardiopulmonary syndrome is characterized by pulmonary capillary leakage and alveolar flooding, resulting in 50% mortality due to fulminant hypoxic respiratory failure. In addition, depression of cardiac function ensues, which complicates the picture with cardiogenic shock. Early diagnosis and appropriate use of extracorporeal membrane oxygenation (ECMO) are amongst the lifesaving interventions in this fatal illness. However, a recent case report demonstrates that implementation of high volume continuous hemofilteration along with protective ventilation reverses the cardiogenic shock within few hours in hantavirus infected patients. This review article is focused on the recent advances in clinical features, diagnosis, management, epidemiology, and pathogenesis of hantavirus induced cardiopulmonary syndrome. It provides information for clinicians to help in correct diagnosis during the early stages of viral infection that could improve the prognosis of this viral illness.

AB - BACKGROUND: Patient-family-healthcare provider interaction seems important for patients with chronic obstructive pulmonary disease (COPD) and their family members' self-management practices. Because the need for support might be enhanced after a hospitalisation, it might be beneficial to explore this interaction further in follow-up health care. AIM: To explore the meaning of patients' and their family members' experiences of interacting with healthcare providers to their daily self-management over time. METHODS: Participant observations and in-depth interviews were conducted repeatedly with 10 patients and seven family members during follow-up visits at hospital and at the participants' homes between 2014 and 2016. A phenomenological-hermeneutical approach was used to interpret the data. RESULTS: 'Between hope and hopelessness' involved frustrations, concerns and doubts, all of which could relate to the interaction with healthcare providers. 'Seeking support from healthcare services', 'navigating between healthcare providers' and 'collaborating with healthcare providers at home' could entail opportunities to strengthen self management and hope; however, it could also entail reduced faith in getting the right help and hopelessness. CONCLUSION: During a period of transition after hospitalisation, available and well-coordinated healthcare services, and alliances with healthcare professionals are crucial to COPD patients and their family members in terms of their self-management, hope and well-being.

PMID- 29446476 TI - The role of human papillomavirus in laryngeal cancer in Southern China. AB - To delineate the role of human papillomavirus (HPV) in laryngeal cancer in Southern Chinese, a retrospective cross-sectional study was conducted in a major otorhinolaryngology referral center in Hong Kong. Eighty-five Chinese patients with histology-confirmed laryngeal squamous cell carcinoma (LSCC) diagnosed between 2005 and 2010 were examined for the status of HPV by PCR, and the expression of p16 and p53 by immunohistochemistry. The HPV, p16 and p53 findings were correlated with clinicopathological features, recurrence and 5-year survival. HPV DNA was detected in one patient (1.2%, 95%CI: 0.2-6.4%) who had glottic cancer and harbored HPV-6. Overexpression of p16 and p53 were detected in 11 (12.9%) and 47 (55.3%) cases, respectively. Recurrence occurred in 22.4% of patients at a median of 13 months. The 5-year overall survival and disease specific survival were 55.7% and 72.4%, respectively. Overexpression of p16 or p53 was not associated with clinicopathological features, recurrence or overall survival. HPV plays a limited role in laryngeal cancer in Hong Kong Southern Chinese. In contrast to oropharyngeal cancer, p16 cannot be used as a surrogate marker for oncogenic involvement of HPV and cannot predict survival in laryngeal cancer. PMID- 29446478 TI - Touch. PMID- 29446477 TI - ATP sensitive K+ channel subunits (Kir6.1, Kir6.2) are the candidate mediators regulating ameliorating effects of pulsed magnetic field on aortic contractility in diabetic rats. AB - Diabetes mellitus is a metabolic disease that causes increased morbidity and mortality in developed and developing countries. With recent advancements in technology, alternative treatment methods have begun to be investigated in the world. This study aims to evaluate the effect of pulsed magnetic field (PMF) on vascular complications and contractile activities of aortic rings along with Kir6.1 and Kir6.2 subunit expressions of ATP-sensitive potassium channels (KATP ) in aortas of controlled-diabetic and non-controlled diabetic rats. Controlled diabetic and non-controlled diabetic adult male Wistar rats were exposed to PMF for a period of 6 weeks according to the PMF application protocol (1 h/day; intensity: 1.5 mT; consecutive frequency: 1, 10, 20, and 40 Hz). After PMF exposure, body weight and blood glucose levels were measured. Then, thoracic aorta tissue was extracted for relaxation-contraction and Kir6.1 and Kir6.2 expression experiments. Blood plasma glucose levels, body weight, and aortic ring contraction percentage decreased in controlled-diabetic rats but increased in non controlled diabetic rats. PMF therapy repressed Kir6.1 mRNA expression in non controlled diabetic rats but not in controlled diabetic rats. Conversely, Kir6.2 mRNA expressions were repressed both in controlled diabetic and non-controlled diabetic rats by PMF. Our findings suggest that the positive therapeutic effects of PMF may act through (KATP ) subunits and may frequently occur in insulin-free conditions. Bioelectromagnetics. 39:299-311, 2018.

AB - Immunological factors, such as cytokines, have been proposed as a cause of changes in the lipid profile of dengue patients. We studied whether serum lipid levels and serum TNF-alpha levels are associated in a group of dengue patients from an endemic region in the Northwest of Mexico. We found statistically important differences in the serum lipid profile and the TNF-alpha levels of dengue patients compared with the control group, were observed. However, TNF alpha levels did not correlate with the lipid profile of dengue patients. PMID- 29446481 TI - Clinical parameters of ovarian hyperstimulation syndrome following different hormonal triggers of oocyte maturation in IVF treatment. AB - OBJECTIVE: Ovarian hyperstimulation syndrome (OHSS) is a serious iatrogenic condition, predominantly related to the hormone used to induce oocyte maturation during IVF treatment. Kisspeptin is a hypothalamic neuropeptide that has recently been demonstrated to safely trigger final oocyte maturation during IVF treatment even in women at high risk of OHSS. However, to date, the safety of kisspeptin has not been compared to current hormonal triggers of oocyte maturation. DESIGN: We conducted a retrospective single-centre cohort study investigating symptoms and clinical parameters of early OHSS in women at high risk of OHSS (antral follicle count or total number of follicles on day of trigger >=23) triggered with human chorionic gonadotrophin (hCG) (n = 40), GnRH agonist (GnRHa; n = 99) or kisspeptin (n = 122) at Hammersmith Hospital IVF unit, London, UK (2013-2016). RESULTS: Clinical Parameters of OHSS: Median ovarian volume was larger following hCG (138 ml) than GnRHa (73 ml; P < .0001), and in turn kisspeptin (44 ml; P < .0001). Median ovarian volume remained enlarged 20-fold following hCG, 8-fold following GnRHa and 5-fold following kisspeptin compared to prestimulation ovarian volumes. Mean (+/-SD) ascitic volumes were lesser following GnRHa (9 +/- 44 ml) and kisspeptin (5 +/- 8 ml) than hCG (62 +/- 84 ml; P < .0001). Symptoms of OHSS were most frequent following hCG and least frequent following kisspeptin. Diagnosis of OHSS: The odds ratio for OHSS diagnosis was 33.6 (CI 12.6-89.5) following hCG and 3.6 (CI 1.8-7.1) following GnRHa, when compared to kisspeptin. CONCLUSION: Triggering oocyte maturation by inducing endogenous gonadotrophin release is preferable to the use of exogenous hCG in women at high risk of OHSS. PMID- 29446482 TI - Oncogenesis as a Selective Force: Adaptive Evolution in the Face of a Transmissible Cancer. AB - Similar to parasites, malignant cells exploit the host for energy, resources and protection, thereby impairing host health and fitness. Although cancer is widespread in the animal kingdom, its impact on life history traits and strategies have rarely been documented. Devil facial tumour disease (DFTD), a transmissible cancer, afflicting Tasmanian devils (Sarcophilus harrisii), provides an ideal model system to monitor the impact of cancer on host life history, and to elucidate the evolutionary arms-race between malignant cells and their hosts. Here we provide an overview of parasite-induced host life history (LH) adaptations, then both phenotypic plasticity of LH responses and changes in allele frequencies that affect LH traits of Tasmanian devils in response to DFTD are discussed. We conclude that akin to parasites, cancer can directly and indirectly affect devil LH traits and trigger host evolutionary responses. Consequently, it is important to consider oncogenic processes as a selective force in wildlife. PMID- 29446483 TI - Adenovirus types associated with severe respiratory diseases: A retrospective 4 year study in Kuwait. AB - Human adenovirus (HAdV) infection can result in a severe respiratory disease. The aim of this study was to identify HAdV types detected in patients hospitalized for severe respiratory illness. The study population consisted of 743 patients with severe respiratory disease admitted to four major hospitals in Kuwait between January 2013 and December 2016. Respiratory specimens were retrospectively screened for 20 respiratory viruses by real-time PCR. The HAdV hexon gene was amplified and directly sequenced, and HAdV types were identified by performing Bayesian phylogenetic analysis. HAdV DNA was detected in 27 (3.6%) patients, with peaks in November and March. Most patients were infants and young children suffering from pneumonia or acute bronchiolitis. The detected HAdV types were C1, C2, C5, B3, and B7. Clusters of HAdV C1, C2, and C5 were observed with high posterior probability. All patients infected with HAdV C5 and 50% of patients infected with HAdV C2 or B7 were admitted to the intensive care unit (ICU). Co-infection with other viruses was detected in 44.4% of patients. The most common co-infecting virus was rhinovirus (HRV). HAdV/HRV co-infection was detected in two children who presumably developed disseminated HAdV infection and died. This is the first report describing the circulation of HAdV types associated with severe outcomes in Kuwait. These findings highlight the need for a national surveillance system to monitor changes in predominant HAdV types and increased numbers of severe respiratory infections. PMID- 29446484 TI - Head position affects the direction of occlusal force during tapping movement. AB - Despite numerous reports describing the relationship between head position and mandibular movement in human subjects, the direction and magnitude of force at the occlusal contacts have not been investigated in relation to head position. The objective was to investigate the effect of head position on the direction of occlusal force while subjects performed a tapping movement. Twenty-three healthy adult subjects were asked to sit on a chair with their back upright and to perform 15 tapping movements in five different head positions: natural head position (control); forward; backward; and right and left rolled. The direction and magnitude of force were measured using a small triaxial force sensor. The Wilcoxon signed-rank test and Bonferroni test were used to compare head positions in each angle of the anteroposterior axis direction and the lateral axis direction with respect to the superior axis. The force element in the anteroposterior axis shifted to the forward direction in the head position pitched backward, compared with control, pitched forward and rolled left positions (P = .02, <.01 and <.01, respectively). The force direction in the lateral axis with the head position rolled to the right or left shifted to the left and right directions, respectively, compared with those in the other positions (P < .05). Results of this study suggest that the head should be maintained in a position in which a stable tapping movement can be performed in a relaxed position without anteroposterior and lateral loading. PMID- 29446485 TI - Effects of glucosamine supplements on painful temporomandibular joint osteoarthritis: A systematic review. AB - The purpose of this study was to systematically review the literature for studies that assessed the effects of glucosamine supplements (GS) on pain and maximum mouth opening (MMO) restriction compared to other therapies, placebo or no intervention on painful temporomandibular joint osteoarthritis (TMJ OA). Randomised controlled trials were selected in a two-phase process. Seven electronic databases, in addition to three grey literature databases, were searched. Risk of bias was assessed using the Cochrane Collaboration's tool for assessing risk of bias in randomised trials. Twelve potentially eligible studies were identified, from which three were finally included. Furthermore, two were categorised at low risk and one at high risk of bias. Intervention groups were treated with glucosamine-sulphate, while controls were treated with placebo or ibuprofen. In two studies, GS were equally effective regarding pain reduction and mouth opening improvement compared to ibuprofen taken two or three times a day over 12 weeks; however, one study did not find significant differences in follow up evaluations concerning these clinical variables in both glucosamine and placebo groups administered over six weeks. There is very low evidence regarding GS therapeutic effects on TMJ OA. Considering a follow-up of 12 weeks, GS were as effective as ibuprofen taken two or three times a day. However, over six weeks of medication intake, GS were not superior to placebo. Still, included studies presented major drawbacks, and therefore, conclusions must be interpreted with caution. PMID- 29446487 TI - TM2D3 rs675436 or FGFR2 rs755793 polymorphisms and susceptibility to Epstein-Barr virus-associated tumors in Chinese Han population. AB - Epstein-Barr virus (EBV) is etiologically linked to nasopharyngeal carcinoma, lymphoma, and gastric carcinoma. The aim of this study was to assess the association of TM2 domain containing 3 (TM2D3) and fibroblast growth factor receptor 2 (FGFR2) SNPs rs675436 and rs755793 with susceptibility to EBV associated tumors in Chinese Han population. Genomic DNA of 415 patients with cancer and 99 healthy controls was assessed using a MALDI-TOF mass spectrometer, and was genotyped in EBV-associated/-negative gastric cancer (EBVa/nGC), EBV associated/-negative nasopharyngeal carcinoma (EBVa/nNPC), EBV-associated/ negative lymphoma (EBVa/nL), and normal controls (NC). The chi-squared (chi2 ) test or Fisher's exact test was used to compare all results and P < 0.05 was considered statistically significant. The results showed that the G-allele of rs675436 was less prevalent in EBVaGC as than in the other groups, while the T allele was more prevalent in EBVaGC (EBVaGC vs EBVnGC: P = 0.005, OR = 10.522, 95%CI = 1.377-80.376; EBVaGC vs NC: P = 0.005, OR = 10.637, 95%CI = 1.392 81.263). Interestingly, the distribution of the genotype and allele frequencies of rs675436 was significantly different between EBVaGC and EBVaNPC. Neither the genotype nor allele frequency of rs755793 was statistically different between any two groups (P > 0.05). These findings indicated that the TT genotype and T allele frequencies of rs675436 were associated with an increased risk of EBVaGC, while allele A or G of rs755793 had no effect on the occurrence of EBV-associated tumors in Chinese Han population. PMID- 29446486 TI - Interleukin-17A participates in podocyte injury by inducing IL-1beta secretion through ROS-NLRP3 inflammasome-caspase-1 pathway. AB - Studies show that the Th17/IL-17A axis plays an important role in the pathogenesis of kidney diseases. Previously, we also showed that IL-17A may play a role in the pathogenesis of primary nephrotic syndrome; however, the underlying mechanism(s) is unclear. The aim of this study was to explore the molecular mechanism of IL-17A-inducing podocyte injury in vitro. In this study, the NLRP3 inflammasome activation and the morphology of podocytes were detected by Western blot and immunofluorescence. The results showed that podocytes persistently expressed IL-17A receptor and that NLRP3 inflammasome in these cells was activated upon exposure to IL-17A. Also, activity of caspase-1 and secretion of IL-1beta increased in the presence of IL-17A. In addition, IL-17A disrupted podocyte morphology by decreasing expression of podocin and increasing expression of desmin. Blockade of intracellular ROS or inhibition of caspase-1 prevented activation of the NLRP3 inflammasome, thereby restoring podocyte morphology. Taken together, the results suggest that IL-17A induces podocyte injury by activating the NLRP3 inflammasome and IL-1beta secretion and contributes to disruption of the kidney's filtration system. PMID- 29446488 TI - Spatial trends in a biomagnifying contaminant: Application of amino acid compound specific stable nitrogen isotope analysis to the interpretation of bird mercury levels. AB - Levels of biomagnifying contaminants are greatest in high-trophic level biota (e.g., predatory birds such as gulls). Gull eggs have been used to assess contaminant spatial patterns and sources, but such assessments must consider how organism trophic position may influence spatial inferences. Stable nitrogen isotopes (delta15 N) in bulk tissue are routinely used in this context. However, bulk delta15 N values are only useful if spatial differences in baseline delta15 N values are considered. Amino acid compound-specific stable nitrogen isotope analysis can generate estimates of baseline delta15 N values and trophic position from the same sample. In the present study, eggs (n = 428) of California (Larus californicus), herring (Larus argentatus smithsonianus), and ring-billed (Larus delawarensis) gulls were used to assess spatial patterns in mercury (Hg) availability in 12 western Canadian lakes located over 14 degrees of latitude, with amino acid compound-specific stable isotope analysis adjustment of egg Hg levels for trophic position. Mean trophic position-adjusted egg Hg levels (micrograms per gram, dry wt) were greatest at sites in receiving waters of the Athabasca River (X- = 0.70) compared to southern (X- = 0.39) and northern (X- = 0.50) regions. Research is required to investigate factors (e.g., local Hg released as a result of human activities, processes influencing Hg methylation) which may be responsible for greater Hg availability in the lower Athabasca River basin. However, it is clear that amino acid compound-specific stable isotope analysis is a valuable tool for assessing contaminant spatial patterns. Environ Toxicol Chem 2018;37:1466-1475. (c) 2018 SETAC. PMID- 29446489 TI - Alcohol attenuates anti-HCV function of IFN-lambda1 through up-regulation of PLASy expression in human hepatic cells. AB - Alcohol could compromise the anti-hepatitis C virus (HCV) function of interferon alpha (IFN-alpha). However, little information is available about the effect of alcohol on interferon-lambda (IFN-lambda, type III IFN), a novel candidate for development of therapy for HCV infection. Huh7 cells were infected with HCV JFH-1 virus, then treated with alcohol, and/or IFN-lambda1. RT-PCR and Western blot were used to detect the levels of HCV and key cellular factors. Overexpression or silencing expression was performed to verify the role of key factors in alcohol attenuated anti-HCV function of IFN-lambda1. Alcohol treatment compromised anti HCV effect of IFN-lambda1 in HCV JFH-1-infected Huh7 cells, evidenced by the significantly increased levels of HCV RNA, and HCV core protein in alcohol-/IFN lambda1-treated cells compared to cells with IFN-lambda1 treatment alone. Investigation of the mechanisms responsible for the alcohol action revealed that alcohol enhanced the expression of protein inhibitor of activated STAT (PIASy). Overexpression of PIASy compromised anti-HCV ability of IFN-lambda1, whereas silencing expression of PIASy partly restored the alcohol-attenuated anti-HCV effect of IFN-lambda1. More importantly, overexpression of PIASy significantly down-regulated the level of IFN-lambda1-indcued phosphorylation of STAT1 (p STAT1), an important adaptor in IFN-lambda pathway, as well as reduced the expression of IFN-lambda1-induced IFN-stimulated genes 56 (ISG56), and myxovirus resistance 1 (Mx1), two antiviral effectors in in IFN-lambda pathway. These findings indicate that alcohol, through inducing the expression of negative regulator in IFN-lambda pathway, inhibits IFN-lambda-mediated anti-HCV action in human hepatic cells, which may lead to the poor efficacy of IFN-lambda-based therapy against HCV infection. PMID- 29446490 TI - A 3-dimensional-printed patient-specific guide system for minimally invasive plate osteosynthesis of a comminuted mid-diaphyseal humeral fracture in a cat. AB - OBJECTIVE: To report the use of a 3-dimensional (3D)-printed patient-specific reduction guide system to facilitate minimally invasive plate osteosynthesis (MIPO) of a humeral fracture in a cat. STUDY DESIGN: Case report. ANIMALS: A 9 year-old male neutered domestic short hair cat weighing 4.4 kg. METHODS: A 9-year old male domestic short hair cat was presented with a comminuted, mid-diaphyseal left humeral fracture. Computed tomographic data were processed to yield 3D mesh representations of both humeri and subsequently manipulated in computer-aided design software. The mirrored, intact humerus was used as a template for appropriate spatial orientation of the major proximal and distal fracture fragments. Patient-specific Ellis pin orientation guides and a reduction guide were designed and 3D printed. The guide system was used intraoperatively to align the major fracture fragments before application of locking internal fixation via standard MIPO surgical portals. RESULTS: Internal fixation of the fracture resulted in appropriate bone alignment. Recovery was uncomplicated, with early return to normal limb function and radiographic evidence of advanced fracture healing after 4 months. CONCLUSION: A 3D-printed patient-specific reduction guide system facilitated accurate alignment of a comminuted humeral fracture during MIPO without intraoperative imaging. PMID- 29446491 TI - Characterization of morphological conversion of Helicobacter pylori under anaerobic conditions. AB - Helicobacter pylori (H. pylori), a gram-negative microaerophilic bacterial pathogen that colonizes the stomachs of more than half of all humans, is linked to chronic gastritis, peptic ulcers and gastric cancer. Spiral-shaped H. pylori undergo morphologic conversion to a viable but not culturable coccoid form when they transit from the microaerobic stomach into the anaerobic intestinal tract. However, little is known about the morphological and pathogenic characteristics of H. pylori under prolonged anaerobic conditions. In this study, scanning electron microscopy was used to document anaerobiosis-induced morphological changes of H. pylori, from helical to coccoid to a newly defined fragmented form. Western blot analysis indicated that all three forms express certain pathogenic proteins, including the bacterial cytotoxin-associated gene A (CagA), components of the cag-Type IV secretion system (TFSS), the blood group antigen-binding adhesin BabA, and UreA (an apoenzyme of urease), almost equally. Similar urease activities were also detected in all three forms of H. pylori. However, in contrast to the helical form, bacterial motility and TFSS activity were found to have been abrogated in the anaerobiosis-induced coccoid and fragmented forms of H. pylori. Notably, it was demonstrated that some of the anaerobiosis-induced fragmented state cells could be converted to proliferation-competent helical bacteria in vitro. These results indicate that prolonged exposure to the anaerobic intestine may not eliminate the potential for H. pylori to revert to the helical pathogenic state. PMID- 29446492 TI - Bayesian reconstruction of the evolutionary history and cross-species transition of variola virus and orthopoxviruses. AB - Variola virus (VARV), the causative agent of smallpox, is an exclusively human virus belonging to the genus Orthopoxvirus, which includes many other viral species covering a wide range of mammal hosts, such as vaccinia, cowpox, camelpox, taterapox, ectromelia, and monkeypox virus. The tempo and mode of evolution of Orthopoxviruses were reconstructed using a Bayesian phylodynamic framework by analysing 80 hemagglutinin sequences retrieved from public databases. Bayesian phylogeography was used to estimate their putative ancestral hosts. In order to estimate the substitution rate, the tree including all of the available Orthopoxviruses was calibrated using historical references dating the South American variola minor clade (alastrim) to between the XVI and XIX century. The mean substitution rate determined by the analysis was 6.5 * 10-6 substitutions/site/year. Based on this evolutionary estimate, the time of the most recent common ancestor of the genus Orthopoxvirus was placed at about 10 000 years before the present. Cowpox virus was the species closest to the root of the phylogenetic tree. The root of VARV circulating in the XX century was estimated to be about 700 years ago, corresponding to about 1300 AD. The divergence between West African and South American VARV went back about 500 years ago (falling approximately in the XVI century). A rodent species is the most probable ancestral host from which the ancestors of all the known Orthopoxviruses were transmitted to the other mammal host species, and each of these species represented a dead-end for each new poxvirus species, without any further inter specific spread. PMID- 29446493 TI - Anti-donor antibody induction following intramuscular injections of allogeneic mesenchymal stromal cells. AB - Allogeneic mesenchymal stromal cells (allo-MSC) are a promising "off-the-shelf" therapy with anti-inflammatory and pro-repair properties. This study investigated humoral immune responses to intramuscular (IM) injections of allo-MSC. Total and isotype-specific anti-donor IgG and donor-specific complement-mediated lysis were determined in sera from healthy mice 2 weeks after single or repeated IM injections of fully mismatched-MHC allo-MSC with comparison to mice receiving syngeneic MSC, allogeneic splenocytes or saline. In mice subjected to hind limb ischemia (HLI), anti-donor IgG was analyzed following IM allo-MSC injection with and without administration of the T-cell immunosuppressant tacrolimus. Recipients of single and repeated IM allo-MSC developed readily-detectable anti-donor IgG. Serum anti-donor IgG levels were similar to those of allo-splenocyte recipients but had higher IgG1/IgG2a ratio and variable capacity for complement-mediated lysis of donor cells. The induced anti-donor IgG bound readily to allo-MSC and this binding was increased following allo-MSC pretreatment with interferon gamma. In mice with HLI, IM injection of allo-MSC into the ischemic limb was also associated with induction of anti-donor IgG but this was abrogated by tacrolimus (FK-506). The results indicate that allo-MSC are inherently immunogenic when delivered intramuscularly to healthy and ischemic mouse hind limb, but induce an IgG1-skewed humoral response that is suppressed by tacrolimus. PMID- 29446494 TI - Prepared for surgery - Communication in nurses' preoperative consultations with patients undergoing surgery for colorectal cancer after a person-centred intervention. AB - AIMS AND OBJECTIVES: To describe preoperative communication after a person centred intervention in nurses' consultations with patients undergoing surgery for colorectal cancer. BACKGROUND: Patients all over the world scheduled for surgery are referred to preoperative consultations with healthcare professionals. The goal is to assess the risk of perioperative complications, improving quality of care and enabling patients to be prepared for surgery and recovery. A person centred intervention was developed, which consisted of an interactive written patient education material and person-centred communication. DESIGN: An explorative quantitative and qualitative study based on 18 audio-taped transcriptions. METHODS: Eighteen patients preoperative nursing consultations at three Swedish hospitals were analysed quantitatively regarding structure: words, time, phases, questions, discursive space, and qualitatively: topics and how the person-centred communication appeared in the consultations. RESULTS: The median time for consultations was 27 min (range 13-64 min). The nurses used two-thirds of the discursive space in the consultations with the patients. The patient education material was used as a support to structure the consultation and discuss sensitive and difficult issues. Seven topics were discussed during the consultation. Two different approaches to communication were identified: Talking with the patient versus Talking to the patient. Talking with the patient (seen as person-centred communication) was defined as: listening to the narrative and confirming each other, raising difficult topics, seeing each other as persons, building on strengths and resources, preparing for surgery and asking open questions. CONCLUSION: Ways of communicating influence how the preoperative consultation develops. Talking with the patient could be seen as person-centred communication in the preoperative care, and when using this approach, the intervention purpose of person-centred communication was met. RELEVANCE TO CLINICAL PRACTICE: Education in person-centred communication is important for nurses to improve their skills in performing preoperative consultations. PMID- 29446495 TI - The role of COBRA-LIKE 2 function, as part of the complex network of interacting pathways regulating Arabidopsis seed mucilage polysaccharide matrix organization. AB - The production of hydrophilic mucilage along the course of seed coat epidermal cell differentiation is a common adaptation in angiosperms. Previous studies have identified COBRA-LIKE 2 (COBL2), a member of the COBRA-LIKE gene family, as a novel component required for crystalline cellulose deposition in seed coat epidermal cells. In recent years, Arabidopsis seed coat epidermal cells (SCEs), also called mucilage secretory cells, have emerged as a powerful model system for the study of plant cell wall components biosynthesis, secretion, assembly and de muro modification. Despite accumulating data, the molecular mechanism of COBL function remains largely unknown. In the current research, we utilized genetic interactions to study the role of COBL2 as part of the protein network required for seed mucilage production. Using correlative phenotyping of structural and biochemical characteristics, unique features of the cobl2 extruded mucilage are revealed, including: 'unraveled' ray morphology, loss of primary cell wall 'pyramidal' organization, reduced Ruthenium red staining intensity of the adherent mucilage layer, and increased levels of the monosaccharides arabinose and galactose. Examination of the cobl2cesa5 double mutant provides insight into the interface between COBL function and cellulose deposition. Additionally, genetic interactions between cobl2 and fei1fei2 as well as between each of these mutants to mucilage-modified 2 (mum2) suggest that COBL2 functions independently of the FEI-SOS pathway. Altogether, the presented data place COBL2 within the complex protein network required for cell wall deposition in the context of seed mucilage and introduce new methodology expending the seed mucilage phenotyping toolbox.

AB - AIMS AND OBJECTIVES: To gain greater understanding of which personal and professional demands novice nurses are confronted with and what can be done to improve the transition from novice to professional staff nurse. BACKGROUND: Novice nurses are confronted with a lot of physical, emotional and intellectual changes in the role-transition process from student nurse to professional staff nurse, which are often related to feelings of confusion, uncertainty and stress. Few studies have investigated, on a longitudinal basis, the lived experiences of novice nurses in the clinical setting. DESIGN: The study adopted a qualitative longitudinal approach to investigate the described experiences of novice nurses during their first 2 years after graduation. Written diaries were selected for optimal data collection. METHODS: A sample of eighteen novice nurses was recruited from several wards at a University Medical Center in the Netherlands. The inclusion criteria were a Bachelor's degree in nursing, aged under 30, and no more than 1 year's work experience. Data were collected from weekly measurements from September 2013-September 2014. RESULTS: Eight major themes emerged from the diaries (n = 580): relatedness, competence, development, organisational context, existential events, goals, autonomy and fit. This study revealed that the need for relatedness was by far the most reported theme. Support and positive feedback from colleagues appeared to be crucial for novices starting work in a highly complex environment. CONCLUSION: This study showed that one of the strategies novice nurses use to deal with challenging and existential situations is to share their experiences with colleagues. Therefore, novice nurses should always work in a safe environment which enables this. RELEVANCE TO CLINICAL PRACTICE: Identification of key issues around understanding novice nurses' first clinical experiences may help to improve their transition from novice to professional staff nurse. The presence and support from supervisors and mentors are inevitable to keep novice nurses motivated for the profession.

AB - In biological systems, nanoparticles (NPs) elicit bioactivity upon interaction with proteins. As a result of post-translational modification, proteins occur in a variety of alternative covalent forms, including structural isomers, which present unique molecular surfaces. We aimed at a detailed description of the recognition of protein isomeric species by NP surfaces. The transient adsorption of isomeric ubiquitin (Ub) dimers by NPs was investigated by solution NMR spectroscopy. Lys63- and Lys48-linked Ub2 were adsorbed by large anionic NPs with different affinities, whereas the binding strength was similar in the cases of smaller particles. After the incorporation of paramagnetic tags into NPs, the observed site-resolved paramagnetic footprints provided a high-resolution map of the different protein surfaces binding to NPs. The approach described could be extended to further protein isoforms and more specialized NP systems to allow better control of the interactions between NPs and protein targets. PMID- 29446498 TI - Simultaneous G-Quadruplex DNA Logic. AB - A fundamental principle of digital computer operation is Boolean logic, where inputs and outputs are described by binary integer voltages. Similarly, inputs and outputs may be processed on the molecular level as exemplified by synthetic circuits that exploit the programmability of DNA base-pairing. Unlike modern computers, which execute large numbers of logic gates in parallel, most implementations of molecular logic have been limited to single computing tasks, or sensing applications. This work reports three G-quadruplex-based logic gates that operate simultaneously in a single reaction vessel. The gates respond to unique Boolean DNA inputs by undergoing topological conversion from duplex to G quadruplex states that were resolved using a thioflavin T dye and gel electrophoresis. The modular, addressable, and label-free approach could be incorporated into DNA-based sensors, or used for resolving and debugging parallel processes in DNA computing applications. PMID- 29446499 TI - Magnetic Switching by the In Situ Electrochemical Control of Quasi-Spin-Peierls Singlet States in a Three-Dimensional Spin Lattice Incorporating TTF-TCNQ Salts. AB - Magnetic phase switching in a coordination polymer is reported, which is demonstrated by combining two processes: (A) the pre-organization of magnetic/redox-active molecules into a framework, and (B) a post-treatment through electrochemical tuning of the pre-organized molecules. A TTF.+ -TCNQ.- salt (TTF=tetrathiafulvalene; TCNQ=7,7,8,8-tetracyano-p-quinodimethane) was incorporated into a three-dimensional framework with paddlewheel-type dimetal(II, II) units ([M2II,II ]; M=Ru with S=1, 1; and Rh with S=0, 2), where the [M2II,II ] and TCNQ.- units form the coordinating framework, and TTF.+ is located in the pores of framework, forming an irregular pi-stacking alternating column with the TCNQ.- in the framework. In 1, the spins of [Ru2II,II ] and TCNQ.- units make a magnetic correlation through the framework upon decreasing the temperature from 300 K, which is, however, suddenly suppressed below 137 K (=Td (1)) by the formation of a spin singlet in the TTF.+ -TCNQ.- columns, as seen in the spin Peierls transition (Td (2)=200 K). This material was incorporated as a cathode in a Li-ion battery (LIB); a long-range ferrimagnetic correlation was formed through the three-dimensional [{Ru2II,II }2 TCNQ]- framework at Tc =78 K in the discharge process. The reversible magnetic phase switching between the non-volatile ferrimagnetic and paramagnetic states, resulting from the local spin tuning of quasi-spin-Peierls singlet, is demonstrated through the discharge/charge cycling of the LIB. PMID- 29446500 TI - Building the foundation to generate a fundamental care standardised data set. AB - AIM AND OBJECTIVES: This paper provides an overview of the current state of performance measurement, key trends and a methodological approach to leverage in efforts to generate a standardised data set for fundamental care. BACKGROUND: Considerable transformation is occurring in health care globally with organisations focusing on achieving the quadruple aim of improving the experience of care, the health of populations, and the experience of providing care while reducing per capita costs of health care. In response, healthcare organisations are employing performance measurement and quality improvement methods to achieve the quadruple aim. Despite the plethora of measures available to health managers, there is no standardised data set and virtually no indicators reflecting how patients actually experience the delivery of fundamental care, such as nutrition, hydration, mobility, respect, education and psychosocial support. CONCLUSIONS: Given the linkages of fundamental care to safety and quality metrics, efforts to build the evidence base and knowledge that captures the impact of enacting fundamental care across the healthcare continuum and lifespan should include generating a routinely collected data set of relevant measures. RELEVANCE TO CLINICAL PRACTICE: This paper provides an overview of the current state of performance measurement, key trends and a methodological approach to leverage in efforts to generate a standardised data set for fundamental care. Standardised data sets enable comparability of data across clinical populations, healthcare sectors, geographic locations and time and provide data about care to support clinical, administrative and health policy decision-making. PMID- 29446501 TI - alpha-Hydroxy Ketones as Masked Ester Donors in Bronsted Base Catalyzed Conjugate Additions to Nitroalkenes. AB - The catalyst-controlled enantioselective direct addition reaction of enolizable esters and related carboxylic acid derivatives to pi electrophiles remains a difficult synthetic transformation. In this study, the suitability of alpha hydroxy ketones as ester equivalents capable of being activated by bifunctional Bronsted base catalysts in the context of conjugate addition reactions to nitroolefins is demonstrated. The scope of the reaction, which affords the corresponding Michael adducts with very high stereoselectivity (diastereomeric ratio (d.r.) >=95:5, up to 99 % enantiomeric excess (ee)), and its limitations are explored, as is the aftermath elaboration of adducts into densely functionalized enantioenriched products. PMID- 29446502 TI - Alcohol, pattern of drinking and all-cause mortality in Russia, Belarus and Hungary: a retrospective indirect cohort study based on mortality of relatives. AB - AIMS: To assess the relationship between alcohol intake frequency and mortality among males and females in three Eastern European populations, and to estimate the additional mortality risk posed by a combination of frequent drinking, binge drinking and other hazardous drinking habits. DESIGN: Retrospective cohort study; the cohort consisted of close relatives of survey participants. SETTING: Middle sized settlements in Russia, Belarus and Hungary. PARTICIPANTS: A total of 124 150 subjects aged 35-69 years in 1998 and followed-up until 2013. MEASUREMENTS: Survey respondents provided information on their mothers, fathers, siblings and partners of female respondents. This information, including current vital status and dates of birth and death, was used to construct the cohort of relatives. Alcohol consumption indices, reported by survey participants, included drinking frequency, binge drinking and hazardous drinking [consuming non-beverage and/or illicitly-produced alcohol and/or heavy drinking over several days (zapoi in Russian)]. FINDINGS: Drinking frequency was associated positively with mortality in all three countries and both genders. At each drinking frequency level, mortality risk increased among those who also engaged in binge and/or hazardous drinking. Regular male drinkers who were also binge drinkers and hazardous drinkers had the highest risk of death; their hazard ratios (HR), compared with non-binge-non-hazardous occasional drinkers, were 2.56 [95% confidence interval (CI) = 2.27-2.88], 2.14 (95% CI = 1.84-2.48) and 2.11 (95% CI = 1.90-2.35) in Russia, Belarus and Hungary, respectively. In women, the corresponding HRs (using a lower frequency cut-off) were 2.86 (95% CI = 1.99-4.12) in Russia, 3.44 (95% CI = 2.17-5.44) in Belarus and 3.01 (95% CI = 2.26-4.01) in Hungary. CONCLUSIONS: Drinking frequency is associated positively with mortality among men and women in Russia, Belarus and Hungary. The mortality risk is higher among frequent drinkers who exhibit binge and hazardous drinking patterns. PMID- 29446503 TI - CRISPR/Cas9-mediated mutagenesis of lncRNA1459 alters tomato fruit ripening. AB - With the development of high-throughput sequencing, many long non-coding RNAs (lncRNAs) have been found to play important roles in diverse biological processes. However, the biological functions of most plant lncRNAs are still unknown. We have previously discovered a tomato ripening-related lncRNA, lncRNA1459. Here, we cloned the full-length lncRNA1459, giving two transcript isoforms. In addition, lncRNA1459 exhibited a specific location in the nucleus. Furthermore, in order to fully identify the function of lncRNA1459 in tomato ripening, loss-of-function mutants of lncRNA1459 were developed using clustered regularly interspaced short palindromic repeats (CRISPR)/-associated protein 9 (Cas9)-induced genome editing technology. Compared with wild-type fruits, the tomato ripening process was significantly repressed in lncRNA1459 mutants. Ethylene production and lycopene accumulation were largely repressed in lncRNA1459 mutants. Additionally, genes related to ethylene and carotenoid biosynthesis were distinctly downregulated in lncRNA1459 mutants compared with wild-type fruits. Moreover, expression of numerous ripening-related genes was changed significantly when lncRNA1459 was knocked out. Expression of potential tomato ripening-related lncRNAs was also specifically changed after knocking out lncRNA1459. Taken together, these results provide insight into the role of lncRNA1459 in tomato fruit ripening. PMID- 29446504 TI - Mechanism of Enolate Transfer between Si and Cu. AB - Exchange of X (F, Cl, OMe) and a substituted enolate chain between SiMe3 and various CuI complexes was examined. Reaction mechanisms pass through a cyclic transition state in which the reaction coordinate is associated with rotation of the SiMe3 moiety. The dependence of the thermodynamic and kinetic features on the nature of the active and ancillary ligands was examined. Formation of copper enolate is shown to be favored when stabilized enolates are used. Replacement of F by Cl reverses the preference of the reaction. This is associated with the small difference between the Cu-Cl and Si-Cl bond energies, in contrast to other Si-X bonds, which are systematically stronger than their Cu-X analogues. PMID- 29446506 TI - Picomolar-scale compound-specific isotope analyses. AB - RATIONALE: We report modifications to compound-specific isotope analyses (CSIA) to enable high-precision isotopic analyses of picomoles of carbon for intact organic molecules. This sample size is two orders of magnitude below the amounts required for commercial systems. The greatly enhanced sensitivity of this system expands molecular isotope studies and applications previously prohibited by low concentrations and small samples. METHODS: We utilize the resolving power and low volumetric flow rates of narrow-bore capillary gas chromatography to improve sample transfer efficiency while maintaining narrow peak widths. Post-column peak broadening is minimized using a micro-fluidic valve for solvent diversion, capillary combustion reactor, narrow-bore capillary transfer lines, and cryogenic water trap. The mass spectrometer was fitted with collector amplifiers configured to 25 ms response times and a data logger board with firmware capable of rapid data acquisition. Carbon dioxide gas was introduced directly into the ion source to evaluate the dynamic range of the system and accuracy and precision of carbon isotope ratio (delta13 C value) measurements. The accuracy and precision for combusted compounds were evaluated using a suite of n-alkanes. RESULTS: For >=30 pmol carbon introduced directly into the ion source, the mean difference between the measured and expected delta13 C values is 0.030/00 (1sigma, n = 57) and the standard deviation of replicate measurements is 0.110/00 (1sigma). The CO2 peak widths generated by the exponential dilution flask were 250 ms and the peak widths produced by combusting n-alkanes were ca 500 ms, less than 25% the width of conventional gas chromatography peaks. For a mixture of 15 n-alkanes (n-C16 to n-C30 ), the accuracy is 0.30/00 (1sigma) and precision is 0.90/00 (1sigma) for replicate delta13 C measurements with 100 pmol carbon per compound on column. CONCLUSIONS: The pico-CSIA method described here offers improved chromatographic resolution and reduces sample size requirements by two orders of magnitude. These advances significantly broaden the available analytical window for CSIA in research areas frequently hindered by sample size limitations, such as forensics, paleoclimate, astrobiology, and biochemistry. PMID- 29446505 TI - ClpC and MecA, components of a proteolytic machine, prevent Spo0A-P-dependent transcription without degradation. AB - In Bacillus subtilis, a proteolytic machine composed of MecA, ClpC and ClpP degrades the transcription factor ComK, controlling its accumulation during growth. MecA also inhibits sporulation and biofilm formation by down-regulating spoIIG and sinI, genes that are dependent for their transcription on the phosphorylated protein Spo0A-P. Additionally, MecA has been shown to interact in vitro with Spo0A. Although the inhibitory effect on transcription requires MecA's binding partner ClpC, inhibition is not accompanied by the degradation of Spo0A, pointing to a previously unsuspected regulatory mechanism involving these proteins. Here, we further investigate the MecA and ClpC effects on Spo0A-P dependent transcription. We show that MecA inhibits the transcription of several Spo0A-P activated genes, but fails to de-repress several Spo0A-P repressed promoters. This demonstrates that MecA and ClpC do not act by preventing the binding of Spo0A-P to its target promoters. Consistent with this, MecA by itself has no effect in vitro on the transcription from PspoIIG while the addition of both MecA and ClpC has a strong inhibitory effect. A complex of MecA and ClpC likely binds to Spo0A-P on its target promoters, preventing the activation of transcription. Thus, components of a degradative machine have been harnessed to directly repress transcription. PMID- 29446507 TI - Technical determinants of biathlon standing shooting performance before and after race simulation. AB - The aim of this study was to identify performance-determining factors in biathlon standing shooting in rest and after intense exercise. Eight Finnish national- and nine junior-team biathletes participated in the study. Participants fired 40 resting shots (REST) and 2 * 5 competition simulation shots (LOAD) after 5 minutes of roller skiing at 95% of peak heart rate. Hit percentage, aiming point trajectory and postural balance were measured from each shot. Cleanness of triggering (ATV, movement of the aiming point 0-0.2 second before the shot) and vertical stability of hold (DevY) were the most important components affecting shooting performance both in REST (DevY, R = -0.61, P < .01; ATV, R = -0.65, P < .01) and in LOAD (DevY, R = -0.50, P < .05; ATV, R = -0.77, P < .001). Postural balance, especially in shooting direction, was related to DevY and ATV. Stability of hold in horizontal (F(1,15) = 7.025, P < .05) and vertical (F(1,15) = 21.285, P < .001) directions, aiming accuracy (F(1,15) = 9.060, P < .01), and cleanness of triggering (F(1,15) = 59.584, P < .001) decreased from REST to LOAD, accompanied by a decrease in postural balance. National- and junior-team biathletes differed only in hit percentage in REST (92 +/- 8% vs 81 +/- 8%, P < .05) and left leg postural balance in shooting direction in LOAD (0.31 +/- 0.18 mm vs 0.52 +/- 0.20 mm, P < .05), and the intense exercise affected the shooting technical components similarly in both national and junior groups. Biathletes should focus on cleanness of triggering and vertical stability of hold in order to improve biathlon standing shooting performance. More stable postural balance in shooting direction could help to improve these shooting technical components. PMID- 29446509 TI - Recovery without autonomy: Progress forward or more of the same for mental health service users? AB - In Western nations, the Recovery approach has become a widely accepted philosophy and treatment concept in mental health. Yet, community understanding of the Recovery approach remains largely unexplored. This study aimed to investigate (i) people's awareness of the principles underpinning the Recovery approach in mental health, and (ii) the treatment approaches people consider most important, and whether these align with the Recovery approach. To achieve these aims, a random sample of 1217 Australian adults participated in the National Social Survey (QSS) via telephone interview. People's experience with mental health services, the importance they place on various treatment approaches, and their awareness of principles underpinning the Recovery approach were assessed. Analyses were conducted using descriptive statistics. Most participants (94%) agreed that 'regardless of the severity of symptoms experienced and/or the mental illness diagnosis, being diagnosed with a mental illness means there is always hope for a meaningful life'. Moreover, most participants considered treatments in line with the Recovery approach as important. However, few participants (35%) agreed with the principle that 'after diagnosis, the person themselves should direct the long term management of their mental illness, rather than a medical professional'. Australian people were to some extent aware of the principles underpinning the Recovery Approach, particularly with regard to hope, ability to live a meaningful life, and the importance of support from family, friends, and others living with mental illness. Nonetheless, autonomy was not highly prioritized, with the prevailing view that management of mental illness should be directed by the medical profession. PMID- 29446508 TI - Accelerated T2 mapping combining parallel MRI and model-based reconstruction: GRAPPATINI. AB - BACKGROUND: Quantitative T2 measurements are sensitive to intra- and extracellular water accumulation and myelin loss. Therefore, quantitative T2 promises to be a good biomarker of disease. However, T2 measurements require long acquisition times. PURPOSE: To accelerate T2 quantification and subsequent generation of synthetic T2 -weighted (T2 -w) image contrast for clinical research and routine. To that end, a recently developed model-based approach for rapid T2 and M0 quantification (MARTINI) based on undersampling k-space, was extended by parallel imaging (GRAPPA) to enable high-resolution T2 mapping with access to T2 w images in less than 2 minutes acquisition time for the entire brain. STUDY TYPE: Prospective cross-sectional study. SUBJECTS/PHANTOM: Fourteen healthy subjects and a multipurpose phantom. FIELD STRENGTH/SEQUENCE: Carr-Purcell Meiboom-Gill sequence at a 3T scanner. ASSESSMENT: The accuracy and reproducibility of the accelerated T2 quantification was assessed. Validations comprised MRI studies on a phantom as well as the brain, knee, prostate, and liver from healthy volunteers. Synthetic T2 -w images were generated from computed T2 and M0 maps and compared to conventional fast spin-echo (SE) images. STATISTICAL TESTS: Root mean square distance (RMSD) to the reference method and region of interest analysis. RESULTS: The combination of MARTINI and GRAPPA (GRAPPATINI) lead to a 10-fold accelerated T2 mapping protocol with 1:44 minutes acquisition time and full brain coverage. The RMSD of GRAPPATINI increases less (4.3%) than a 10-fold MARTINI reconstruction (37.6%) in comparison to the reference. Reproducibility tests showed low standard deviation (SD) of T2 values in regions of interest between scan and rescan (<0.4 msec) and across subjects (<4 msec). DATA CONCLUSION: GRAPPATINI provides highly reproducible and fast whole-brain T2 maps and arbitrary synthetic T2 -w images in clinically compatible acquisition times of less than 2 minutes. These abilities are expected to support more widespread clinical applications of quantitative T2 mapping. LEVEL OF EVIDENCE: 2 Technical Efficacy: Stage 1 J. MAGN. RESON. IMAGING 2018;48:359-368. PMID- 29446510 TI - Use of T1 relaxation time in rotating frame (T1 rho) and apparent diffusion coefficient to estimate cerebral stroke evolution. AB - BACKGROUND: The major factor for the appropriate treatment strategies for ischemia patients is its onset timing. PURPOSE/HYPOTHESIS: To study to evaluate the diagnostic accuracy of T1 relaxation time in a rotating frame (T1 rho) and apparent diffusion coefficient (ADC) from MRI to estimate ischemia stages. STUDY TYPE: Prospective. POPULATION/SUBJECTS/PHANTOM/SPECIMEN/ANIMAL MODEL: In all, 73 patients (49 males, aged 29-78 years and 24 females, aged 22-94 years) with ischemia were prospectively imaged with T1 rho and diffusion MRI during the postischemic period. FIELD STRENGTH/SEQUENCE: 3T/T1 rho and diffusion-weighted imaging (DWI). ASSESSMENT: Ischemic parenchyma included tissue with elevated signal areas on DWI and correlative hypointense areas on ADC maps. STATISTICAL TESTS: The sensitivity of variables to ischemia time was quantified by analyzing the respective correlations of these values with onset time. RESULTS: DeltaT1 rho (ipsilateral-contralateral differences in T1 rho) (R2 = 0.956) and T1 rhoipsi (ipsilateral ischemia T1 rho values) (R2 = 0.941) were elevated in all ischemic lesions; these values increased linearly as a function of time, unlike DeltaADC (ipsilateral-contralateral differences in ADC) (R2 = -0.410) and ADCipsi (ipsilateral ischemia ADC values) (R2 = 0.550). DeltaT1 rho and T1 rhoipsi were significantly different between all stages (P < 0.01), except the acute and hyperacute stages (P = 0.589 for DeltaT1 rho, P = 0.290 for T1 rhoipsi , respectively), but DeltaADC and ADCipsi only between the late subacute and early subacute stages (P < 0.01) and the late subacute and chronic stages (P < 0.01). DATA CONCLUSION: These data suggest that T1 rho can provide estimates for the ischemic time in patients. T1 rho has the potential to outperform diffusion for single-timepoint examination because the T1 rho change during strokes is positive and linear. If patients with suspected stroke are scanned by MRI within the appropriate timeframe, T1 rho may provide tools for evaluating stroke onset, potentially aiding in treatment strategies.

PMID- 29446511 TI - Long-term study of tubeless insulin pump therapy compared to multiple daily injections in youth with type 1 diabetes: Data from the German/Austrian DPV registry. AB - OBJECTIVE: To examine glycemic control in youth with type 1 diabetes (T1D) who switched from multiple daily injections (MDI) to a tubeless insulin pump (Omnipod Insulin Management System, Insulet Corporation, Billerica, Massachusetts) compared to patients who continued MDI therapy over a 3-year time period. RESEARCH DESIGN AND METHODS: This retrospective analysis of the German/Austrian Diabetes Patienten Verlaufsdokumentation registry included data from 263 centers and 2529 patients <20 years (n = 660 tubeless insulin pump; n = 1869 MDI) who initiated treatment on a tubeless insulin pump as of January 1, 2013 and had 1 year of data preswitch from MDI and 3 years of data postswitch to a tubeless pump. Outcomes included the change in glycated hemoglobin (HbA1c), insulin dose, and body mass index (BMI) SD score (SDS). RESULTS: Youth with T1D who switched from MDI therapy to a tubeless insulin pump showed better glycemic control at 1 year compared to patients who continued MDI treatment, adjusted mean +/- SE: 7.5% +/- 0.03% (58 mmol/mol) vs 7.7% +/- 0.02% (61 mmol/mol); P < .001, with no between-group difference at 2 and 3 years. Total daily insulin dose was lower (P < .001) in the tubeless insulin pump group, 0.80 +/- 0.01, 0.81 +/- 0.01, and 0.85 +/- 0.01 U/kg, vs the MDI group, 0.89 +/- 0.01, 0.94 +/- 0.01, and 0.97 +/- 0.01 U/kg, at 1, 2, and 3 years, respectively (all P < .001). BMI SDS increased in both groups and was not different over time. CONCLUSIONS: Treatment with a tubeless insulin pump in youth with T1D was associated with improvements in glycemic control compared to MDI after 1 year and appears to be an effective alternative to MDI. PMID- 29446512 TI - Nursing staff-led behavioural group intervention in psychiatric in-patient care: Patient and staff experiences. AB - A promising intervention in mental health in-patient care is behavioural activation (BA). Interventions based on BA can be used by mental health nurses and other staff members. The aim of this study was to evaluate patients' and staff members' experiences of a nursing staff-led behavioural group intervention in mental health in-patient care. The intervention was implemented at three adult acute general mental health in-patient wards in a public hospital setting in Sweden. A self-administrated questionnaire, completed by 84 patients and 34 nurses and nurse assistants, was administered, and nonparametric data analysed using descriptive statistics. Our findings revealed that both patients and nursing staff ranked nursing care and care environment as important aspects in the recovery process. Patients and staff members reported overall positive experiences of the group sessions. Patients with higher frequencies of attendance and patients satisfied with overall care had a more positive attitude towards the intervention. A more positive experience of being a group leader was reported by staff members who had been leading groups more than ten times. The most common impeding factor during implementation, reported by staff members, was a negative attitude to change. Conducive factors were having support from a psychologist and the perception that patients were showing interest. These positive experiences reported by patients and nursing staff, combined with previous research in this field, are taking us one step further in evaluating group sessions based on BA as a meaningful nursing intervention in mental health in-patient care. PMID- 29446513 TI - A systematic review of clinical supervision evaluation studies in nursing. AB - According to the international, extant literature published during the last 20 years or so, clinical supervision (CS) in nursing is now a reasonably common phenomenon. Nevertheless, what appears to be noticeably 'thin on the ground' in this body of literature are empirical evaluations of CS, especially those pertaining to client outcomes. Accordingly, the authors undertook a systematic review of empirical evaluations of CS in nursing to determine the state of the science. Adopting the approach documented by Stroup et al. (JAMA, 283, 2000, 2008), the authors searched for reports of evaluation studies of CS in nursing - published during the years 1995 to 2015. Keywords for the search were 'clinical supervision', 'evaluation', 'efficacy', 'nursing', and combinations of these keywords. Electronic databases used were CINAHL, MEDLINE, PsychLIT, and the British Nursing Index. The research evidence from twenty-eight (28) studies reviewed is presented, outlining the main findings with an overview of each study presented. The following broad themes were identified and are each discussed in the study: narrative/anecdotal accounts of positive outcomes for clinical supervision, narrative/anecdotal accounts of negative outcomes for clinical supervision, empirical positive outcomes reported by supervisee, and empirical findings showing no effect by supervisee. PMID- 29446515 TI - Long-term monitoring of an amphibian community after a climate change- and infectious disease-driven species extirpation. AB - Infectious disease and climate change are considered major threats to biodiversity and act as drivers behind the global amphibian decline. This is, to a large extent, based on short-term studies that are designed to detect the immediate and strongest biodiversity responses to a threatening process. What few long-term studies are available, although typically focused on single species, report outcomes that often diverge significantly from the short-term species responses. Here, we report the results of an 18-year survey of an amphibian community exposed to both climate warming and the emergence of lethal chytridiomycosis. Our study shows that the impacts of infectious disease are ongoing but restricted to two out of nine species that form the community, despite the fact all species can become infected with the fungus. Climate warming appears to be affecting four out of the nine species, but the response of three of these is an increase in abundance. Our study supports a decreasing role of infectious disease on the community, and an increasing and currently positive effect of climate warming. We caution that if the warming trends continue, the net positive effect will turn negative as amphibian breeding habitat becomes unavailable as water bodies dry, a pattern that already may be underway.

PMID- 29446517 TI - Coumarin Photocaging Groups Modified with an Electron-Rich Styryl Moiety at the 3 Position: Long-Wavelength Excitation, Rapid Photolysis, and Photobleaching. AB - A new class of coumarin photocaging groups modified with an electron-rich styryl moiety at the 3-position was constructed. The large pi-conjugated structure and stabilization of the carbocation intermediates by electron donors endowed the new photocaging groups with excellent long-wavelength absorption, large two-photon absorption cross-sections, and high uncaging quantum yields. Moreover, the new photocaging groups displayed unique photobleaching properties after photocleavage as a result of the intramolecular cyclization rearrangement of a carbocation intermediate to form five-membered ring byproducts and block the styryl conjugation at the 3-position. These superior properties of the new photocaging groups are extremely beneficial for high-concentration samples and thick specimens, thus extending the application of photocaging groups in many fields. PMID- 29446518 TI - Interwoven histories: Mental health nurses with experience of mental illness, qualitative findings from a mixed methods study. AB - The effects of mental health nurses' own experience of mental illness or being a carer have rarely been researched beyond the workplace setting. This study aimed to explore how the experience of mental illness affects mental health nurses' lives outside of and inside work. A sample of 26 mental health nurses with personal experience of mental illness took part in semistructured interviews. Data were analysed thematically using a six-phase approach. The analysis revealed the broad context of nurses' experiences of mental illness according to three interwoven themes: mental illness as part of family life; experience of accessing services; and life interwoven with mental illness. Participants typically described personal and familial experience of mental illness across their life course, with multiple causes and consequences. The findings suggest that nurses' lives outside of work should be taken into account when considering the impact of their personal experience of mental illness. Similarly being a nurse influences how mental illness is experienced. Treatment of nurses with mental illness should account for their nursing expertise whilst recognizing that the context for nurses' mental illness could be much broader than the effect of workplace stress.

AB - OBJECTIVES: To describe the incidence and prevalence of type 1 diabetes among pediatric dependents of the US Department of Defense. METHODS: The Military Health System (MHS) data repository was used to identify pediatric patients (<=17 years of age) with type 1 diabetes from January 1, 2007 to December 31, 2012. Annual incidence, annual prevalence and adjusted incidence were calculated and stratified by sex, age group, and region of residence. RESULTS: Within a 6-year study period from 2007 to 2012, 5616 pediatric patients with type 1 diabetes were identified; 57% male, mean (SD) age of 10.9 (4.2) years. Annual type 1 diabetes incidence (per 100 000 persons) over the 5-year time period ranged from 20.7/100 000 to 21.3/100 000. Incidence for each year was highest in the 10 to 14 years age group and ranged from 30.9/100 000 in 2008 to 35.2/100 000 in 2011. Annual type 1 diabetes prevalence (per 1000 persons) remained stable throughout the study period at 1.5/1000. Adjusted incidence for males was significantly higher compared to females (21.0/100 000 vs 18.1/100 000; P = .001). During the study period, annual incidence remained steady (test for trend, P = .984). CONCLUSIONS: The incidence of type 1 diabetes among children appears to plateau during the study period, suggesting a steady state of type 1 diabetes within this pediatric population. The MHS provides an accurate and up to date look at incidence of type 1 diabetes and may reflect broader trends of incidence of pediatric disease for the United States as a whole.

AB - INTRODUCTION: Lenalidomide is a thalidomide analog with anti-angiogenic properties. Previous case reports suggest its efficacy in preventing gastrointestinal bleeding (GIB) secondary to angiodysplasia (AD) in hereditary haemorrhagic telangiectasia and potentially in reversing AD. We present the first case series to explore lenalidomide as a treatment for AD-related GIB in patients with von Willebrand disease (VWD). METHODS: A retrospective chart review was conducted to include patients with VWD, who were evaluated from 2010 to 2013 and who had received lenalidomide to treat recurrent GIB secondary to AD. All patients had failed single-agent use of antifibrinolytic agents. Patients were observed for at least 2 years on therapy. RESULTS: Five patients (3 males; 68.2 +/- 4.9 years) with VWD (3 with type 3 and 1 each with types 1 and 2a) and AD were found. Sites of AD included the stomach, duodenum, jejunum and colon. Lenalidomide was started at 5 mg oral daily. Uptitration to 10 and 15 mg in 1 patient each was necessary due to recurrence of GIB. The mean number of endoscopies performed for control of GIB post lenalidomide was significantly lower compared to pretherapy (0.25 vs 5.50; P = .001). Mean bleed-free duration on lenalidomide was 12.6 +/- 4.7 months. Three patients have reported no GIB on lenalidomide. CONCLUSION: This case series demonstrates significantly reduced number of endoscopies and increased bleed-free duration with lenalidomide treatment in selected patients with VWD and recurrent GIB from AD. Prospective multicenter trials are needed to further define the role of lenalidomide in the management of GIB from angiodysplasia and VWD.

AB - Gelation mechanism is of utmost importance to the rational design of supramolecular hydrogelators. Although both kinetic and thermodynamic controlled self-assembly processes have been widely studied in hydrogels, the formation relationship between crystalline and amorphous gel networks still remains ambiguous. Herein, a gelation transformation from a kinetic to a thermodynamic process was achieved by balancing the rigidity and flexibility of the inorganic organic co-assemblies. By using polyoxometalates and zwitterionic amphiphiles, the transition morphologies between crystalline and amorphous hydrogel networks were evidenced for the first time, as ordered wormlike micelles. Given the versatile applications of hydrogels in biological systems and materials science, these findings may highlight the potential of inorganic-organic binary supramolecular hydrogelators and fill in the blank between kinetic and thermodynamic controlled gelation processes.

AB - The safety of triple oral therapy with dapagliflozin plus saxagliptin plus metformin versus dual therapy with dapagliflozin or saxagliptin plus metformin was compared in a post-hoc analysis of 3 randomized trials of sequential or concomitant add-on of dapagliflozin and saxagliptin to metformin. In the concomitant add-on trial, patients with type 2 diabetes on stable metformin received dapagliflozin 10 mg/d plus saxagliptin 5 mg/d. In sequential add-on trials, patients on metformin plus either saxagliptin 5 mg/d or dapagliflozin 10 mg/d received dapagliflozin 10 mg/d or saxagliptin 5 mg/d, respectively, as add on therapy. After 24 weeks, incidences of adverse events and serious adverse events were similar between triple and dual therapy and between concomitant and sequential add-on regimens. Urinary tract infections were more common with sequential than with concomitant add-on therapy; genital infections were reported only with sequential add-on of dapagliflozin to saxagliptin plus metformin. Hypoglycaemia incidence was <2.0% across all analysis groups. In conclusion, the safety and tolerability of triple therapy with dapagliflozin, saxagliptin and metformin, as either concomitant or sequential add-on, were similar to dual therapy with either agent added to metformin. PMID- 29446524 TI - Impact of blood flow-restricted bodyweight exercise on skeletal muscle adaptations. AB - This study ascertains the ability of bodyweight blood flow-restricted (BFR) exercise training to promote skeletal muscle adaptations of significance for muscle accretion and metabolism. Six healthy young individuals (three males and three females) performed six weeks of bodyweight BFR training. Each session consisted of five sets of sit-to-stand BFR exercise to volitional failure with 30 second inter-set recovery. Prior to, and at least 72 h after training, muscle biopsies were taken from m. vastus lateralis to assess changes in fibre type specific cross-sectional area (CSA), satellite cell (SC) and myonuclei content and capillarization, as well as mitochondrial protein expression. Furthermore, magnetic resonance imaging was used to assess changes in whole thigh muscle CSA. Finally, isometric knee extensor muscle strength was evaluated. An increase in knee extensor whole muscle CSA was observed at middle and distal localizations after training (3.2% and 3.5%, respectively) (P<0.05), and a trend was observed towards an increase in type I fibre CSA, whereas muscle strength did not increase. Additionally, the number of SCs and myonuclei associated with type I fibres increased by 65.7% and 20%, respectively (P<0.05). No significant changes were observed in measures of muscle capillarization and mitochondrial proteins. In conclusion, six weeks of bodyweight-based BFR exercise promoted myocellular adaptations related to muscle accretion, but not metabolic properties. Moreover, the study revealed that an appropriate total training volume needs further investigation before recommending bodyweight BFR to patient populations. PMID- 29446526 TI - The SCN9A channel and plasma membrane depolarization promote cellular senescence through Rb pathway. AB - Oncogenic signals lead to premature senescence in normal human cells causing a proliferation arrest and the elimination of these defective cells by immune cells. Oncogene-induced senescence (OIS) prevents aberrant cell division and tumor initiation. In order to identify new regulators of OIS, we performed a loss of-function genetic screen and identified that the loss of SCN9A allowed cells to escape from OIS. The expression of this sodium channel increased in senescent cells during OIS. This upregulation was mediated by NF-kappaB transcription factors, which are well-known regulators of senescence. Importantly, the induction of SCN9A by an oncogenic signal or by p53 activation led to plasma membrane depolarization, which in turn, was able to induce premature senescence. Computational and experimental analyses revealed that SCN9A and plasma membrane depolarization mediated the repression of mitotic genes through a calcium/Rb/E2F pathway to promote senescence. Taken together, our work delineates a new pathway, which involves the NF-kappaB transcription factor, SCN9A expression, plasma membrane depolarization, increased calcium, the Rb/E2F pathway and mitotic gene repression in the regulation of senescence. This work thus provides new insight into the involvement of ion channels and plasma membrane potential in the control of senescence. PMID- 29446527 TI - Nonbinary quantification technique accounting for myocardial infarct heterogeneity: Feasibility of applying percent infarct mapping in patients. AB - BACKGROUND: Binary threshold-based quantification techniques ignore myocardial infarct (MI) heterogeneity, yielding substantial misquantification of MI. PURPOSE: To assess the technical feasibility of MI quantification using percent infarct mapping (PIM), a prototype nonbinary algorithm, in patients with suspected MI. STUDY TYPE: Prospective cohort POPULATION: Patients (n = 171) with suspected MI referred for cardiac MRI. FIELD STRENGTH/SEQUENCE: Inversion recovery balanced steady-state free-precession for late gadolinium enhancement (LGE) and modified Look-Locker inversion recovery (MOLLI) T1 -mapping on a 1.5T system. ASSESSMENT: Infarct volume (IV) and infarct fraction (IF) were quantified by two observers based on manual delineation, binary approaches (2-5 standard deviations [SD] and full-width at half-maximum [FWHM] thresholds) in LGE images, and by applying the PIM algorithm in T1 and LGE images (PIMT1 ; PIMLGE ). STATISTICAL TEST: IV and IF were analyzed using repeated measures analysis of variance (ANOVA). Agreement between the approaches was determined with Bland Altman analysis. Interobserver agreement was assessed by intraclass correlation coefficient (ICC) analysis. RESULTS: MI was observed in 89 (54.9%) patients, and 185 (38%) short-axis slices. IF with 2, 3, 4, 5SDs and FWHM techniques were 15.7 +/- 6.6, 13.4 +/- 5.6, 11.6 +/- 5.0, 10.8 +/- 5.2, and 10.0 +/- 5.2%, respectively. The 5SD and FWHM techniques had the best agreement with manual IF (9.9 +/- 4.8%) determination (bias 1.0 and 0.2%; P = 0.1426 and P = 0.8094, respectively). The 2SD and 3SD algorithms significantly overestimated manual IF (9.9 +/- 4.8%; both P < 0.0001). PIMLGE measured significantly lower IF (7.8 +/- 3.7%) compared to manual values (P < 0.0001). PIMLGE , however, showed the best agreement with the PIMT1 reference (7.6 +/- 3.6%, P = 0.3156). Interobserver agreement was rated good to excellent for IV (ICCs between 0.727-0.820) and fair to good for IF (0.589-0.736). DATA CONCLUSION: The application of the PIMLGE technique for MI quantification in patients is feasible. PIMLGE , with its ability to account for voxelwise MI content, provides significantly smaller IF than any thresholding technique and shows excellent agreement with the T1 -based reference.

AB - BACKGROUND: A meta-analysis was conducted to investigate the diagnostic performance of computed tomography (CT) imaging features of ground-glass opacity (GGO) to predict invasiveness. METHODS: Two reviewers independently searched PubMed, Medline, Web of Science, Cochrane Embase and CNKI for relevant studies. CT imaging signs of bubble lucency, speculation, lobulated margin, and pleural indentation were used as diagnostic references to discriminate pre-invasive and invasive disease. The sensitivity, specificity, diagnostic odds ratio (DOR), summary receiver operating characteristic (SROC) curves, and the area under the SROC curve (AUC) were calculated to evaluate diagnostic efficiency. RESULTS: Twelve studies were finally included. Diagnostic performance ranged from 0.41 to 0.52 for sensitivity and 0.56 to 0.63 for specificity. The diagnostic positive and negative likelihood ratios ranged from 1.03 to 2.13 and 0.52 to 1.05, respectively. The DORs of the GGO CT features for discriminating invasive disease ranged from 1.02 to 4.00. The area under the ROC curve was also low, with a range of 0.60 to 0.67 for discriminating pre-invasive and invasive disease. CONCLUSION: The diagnostic value of a single CT imaging sign of GGO, such as bubble lucency, speculation, lobulated margin, or pleural indentation is limited for discriminating pre-invasive and invasive disease because of low sensitivity, specificity, and AUC. PMID- 29446525 TI - Laboratory testing for factor VIII and IX inhibitors in haemophilia: A review. AB - Inhibitors are antibodies directed against haemophilia treatment products which interfere with their function. Factor VIII (FVIII) inhibitors in haemophilia A and factor IX (FIX) inhibitors in haemophilia B are significant clinically when they require a change in a patient's treatment regimen. Their persistence may increase morbidity and mortality. Multiple laboratory tests are now available for detecting and understanding inhibitors in haemophilia. Inhibitors are traditionally measured by their interference in clotting or chromogenic factor assays. They may also be detected using immunologic assays, such as enzyme-linked immunosorbent assay or fluorescence immunoassay. Anti-FVIII or anti-FIX antibodies of IgG4 subclass best correlate with the presence of functional inhibitors. Improvements in inhibitor measurement have been recently introduced. Preanalytical heat treatment of patient specimens allows testing of patients without delaying treatment. Use of chromogenic and immunologic assays may aid in identification of false-positive results, which are frequent among low-titre inhibitors. Validated reagent substitutions can be used to reduce assay cost. New methods for defining assay positivity and reporting low-titre inhibitors have been suggested. Challenges remain in the areas of quality control, assay standardization, monitoring of patients undergoing immune tolerance induction therapy and testing in the presence of modified and novel treatment products. PMID- 29446529 TI - Educational disparities in the associations between self-monitoring of blood glucose and glycemic control in type 2 diabetes patients in Xiamen, China. AB - BACKGROUND: This study examined the combined effects of self-monitoring of blood glucose (SMBG) and educational attainment on glycemic control in type 2 diabetes mellitus (T2DM) patients. METHODS: A cross-sectional survey was performed among community residents with T2DM. Good glycemic control was defined as HbA1c <7% in the most recent measurement. Multivariable logistic regression was used to examine associations of glycemic control with SMBG, educational attainment, and their combined effects by controlling for certain covariates, with further stratification by sex. RESULTS: Complete data were available for 798 patients, of which 58.52% had good glycemic control. Higher education and SMBG were associated with good glycemic control (P < 0.05). In the SMBG group, tertiary-educated patients had the greatest odds of good glycemic control (odds ratios 2.56; 95% confidence interval 1.31-4.99). Among those performing SMBG, the odds of good glycemic control were higher for those with higher education levels (Ptrend = 0.003), whereas there was no clear trend for those not performing SMBG (Ptrend = 0.071). For subjects attaining secondary and tertiary education levels, the odds of good glycemic control were higher in those performing SMBG, although there was no significant difference between the two groups for those with a primary education. Glycemic control decreased slightly among males with a primary level education, but showed an increasing trend among females with a primary level education. CONCLUSIONS: Sex-specific educational disparities exist in the association between SMBG and glycemic control. More detailed guidelines for SMBG according to a subject's socioeconomic position and sex are required. PMID- 29446530 TI - A novel tissue-based beta-catenin gene and immunohistochemical analysis to exclude familial adenomatous polyposis among children with hepatoblastoma tumors. AB - BACKGROUND: The Wnt/beta-catenin pathway plays a central role in the pathogenesis of most hepatoblastomas (HBs), that is, up to 60-80% carry activating CTNNB1 mutations. HBs can however also be the first manifestation of familial adenomatous polyposis (FAP). As this is a severe disease, it is important for the patient and related family members to firmly exclude FAP at an early stage. Current diagnosis largely depends on APC germline mutation detection on genomic DNA, which is associated with 10-20% false-negative results. Here, we establish and validate a tissue-based beta-catenin gene and immunohistochemical analysis, which complements germline mutation screening to exclude the diagnosis of FAP among HB patients. METHODS: Tumor tissues of 18 HB patients, including three FAP cases were subjected to CTNNB1 exon 3 mutational analysis and immunohistochemistry comparing staining patterns for total and exon 3 specific beta-catenin antibodies. RESULTS: Our novel tissue-based method reliably identified all three FAP patients. Their tumors were characterized by a wild-type exon 3 sequence and a comparable nuclear staining for both antibodies. In contrast, the non-FAP tumors carried missense CTNNB1 mutations combined with a clearly reduced staining for the exon 3 antibody, or complete loss of staining in case of lesions with exon 3 deletions. CONCLUSION: We have successfully established and validated a novel beta-catenin gene and immunohistochemical diagnostic method, which, when combined with routine germline DNA testing, allows the exclusion of the diagnosis of FAP among HB patients.

PMID- 29446533 TI - Forms of Capital and Habitus in the Decision to Go on Academic Exchange. AB - Although Canadian universities have made internationalization a strategic priority, only few Canadian students currently participate in any international study opportunities. Drawing on interviews with Canadian students who were about to spend some of their undergraduate education abroad as exchange students, or had recently returned from a study exchange, we argue that despite the importance of relatively high costs associated with international study experiences, cultural factors play a more important role in enabling the decision to study abroad. Being habitually exposed to travel in one's family, and having been encouraged to travel independently as a teenager or young adult emerge as important precursors to our participants' decision to take part in study exchanges. Although one needs to engage critically with university administrators' current preoccupation with internationalization, being exposed to an extended time abroad has shown to have positive effects, especially for otherwise underprivileged students. Given the exploratory nature of this study, we conclude with suggestions for further research aimed at confirming our findings and developing policy. PMID- 29446534 TI - Habitat Maintenance and Local Economic Ethics in Rural Atlantic Canada. AB - Inspired by Jane Jacobs's writing on "habitat maintenance," this paper seeks to identify the ethics that sometimes compel rural residents to act in ways that preserve their communities in the long run, despite short-term incentives to do otherwise. Data from focus groups in four rural Atlantic Canadian communities suggest shared ethics around entrepreneurship, market competition, buying local, and subsistence, some of which underlie the rural practices and perspectives that appear, to some outsiders, as irrational and "backwards." Understanding these ethics and the practices they incite as components of habitat maintenance-and judging them by their situated pragmatism rather than their fit with the placeless ideologies of growth-centric global capitalism and competitiveness highlights their rationality and utility. Findings could help direct discussions of rural economic development toward notions of prosperity, sustainability, and economy that fit better with rural realities. PMID- 29446535 TI - Translocality, Network Structure, and Music Worlds: Underground Metal in the United Kingdom. AB - Translocal music worlds are often defined as networks of local music worlds. However, their networked character and more especially their network structure is generally assumed rather than concretely mapped and explored. Formal social network analysis (SNA) is beginning to attract interest in music sociology but it has not previously been used to explore a translocal music world. In this paper, drawing upon a survey of the participation of 474 enthusiasts in 148 live music events, spread across 6 localities, we use SNA to explore a significant "slice" of the network structure of the U.K.'s translocal underground heavy metal world. Translocality is generated in a number of ways, we suggest, but one way, the way we focus upon, involves audiences traveling between localities to attend gigs and festivals. Our analysis of this network uncovers a core-periphery structure which, we further find, maps onto locality. Not all live events enjoy equal standing in our music world and some localities are better placed to capture more prestigious events, encouraging inward travel. The identification of such structures, and the inequality they point to, is, we believe, one of several benefits of using SNA to analyze translocal music worlds.

PMID- 29446537 TI - Replacing the Canadianization Generation: An Examination of Faculty Composition from 1977 through 2017. AB - Amid growing numbers of doctoral graduates entering an increasingly competitive global academic job market, concerns about equity in the hiring process and the value of the Canadian Ph.D. are mounting. Grounded within the historical context of the Canadianization Movement, we examine the doctoral credentials of 4,934 U15 social science faculty between 1977 and 2017 to understand the ebb and flow of incoming and outgoing faculty across the country's academic field. Our trend analyses reveal an overall increase in the proportion of Canadian-trained faculty hires with the noted exceptions of Canada's top three universities who display a strong presence of high-status American-trained faculty throughout. Results from the contemporary period, between 1997 and 2017, reveal a time of retirement during which outgoing Canadian-trained faculty are replaced with increasing proportions of American-trained academics.

AB - There has been growing discussion surrounding the phenomenon of Islamophobia in Western societies over the last few years. However, in-depth empirical research of the prevalence and patterns of prejudice toward Muslims remains scarce, especially in the Canadian context. With data from the 2011 Canadian Election Study and the 2014 General Social Survey, this study measures the extent to which negative feelings toward Muslims are present among the general adult population, and the extent to which Muslim Canadians themselves say they have experienced discrimination in recent years due to their religion, ethnicity, and culture. PMID- 29446539 TI - Corrigendum. PMID- 29446540 TI - The Institution of Sociological Theory in Canada. AB - Using theory syllabi and departmental data collected for three academic years, this paper investigates the institutional practice of theory in sociology departments across Canada. In particular, it examines the position of theory within the sociological curriculum, and how this varies among universities. Taken together, our analyses indicate that theory remains deeply institutionalized at the core of sociological education and Canadian sociologists' self-understanding; that theorists as a whole show some coherence in how they define themselves, but differ in various ways, especially along lines of region, intellectual background, and gender; that despite these differences, the classical versus contemporary heuristic largely cuts across these divides, as does the strongly ingrained position of a small group of European authors as classics of the discipline as a whole. Nevertheless, who is a classic remains an unsettled question, alternatives to the "classical versus contemporary" heuristic do exist, and theorists' syllabi reveal diverse "others" as potential candidates. Our findings show that the field of sociology is neither marked by universal agreement nor by absolute division when it comes to its theoretical underpinnings. To the extent that they reveal a unified field, the findings suggest that unity lies more in a distinctive form than in a distinctive content, which defines the space and structure of the field of sociology. PMID- 29446541 TI - Group-Based Diet and Physical Activity Weight-Loss Interventions: A Systematic Review and Meta-Analysis of Randomised Controlled Trials. AB - BACKGROUND: Many weight-loss interventions are delivered in groups but evidence on their effectiveness, and characteristics associated with effectiveness, is limited. We synthesised evidence on (1) design and delivery of group-based weight loss interventions; (2) effectiveness; and (3) associations between intervention characteristics, change techniques, and effectiveness. METHODS: Five online databases were searched to May 2017 for randomised controlled trials (RCTs) of group-based diet and/or physical activity interventions for overweight/obese adults (BMI >= 25). Intervention characteristics were synthesised narratively. Mean differences (MD) in weight loss were calculated using a random-effects meta analysis, and sub-group analyses were conducted to identify moderators of effectiveness. RESULTS: Forty-seven RCTs reporting 60 evaluations of group-based interventions were included. MD in weight loss between intervention and control groups was -3.49 [95% CI -4.15, -2.84], -3.44 [-4.23, -2.85], and -2.56 kg [ 3.79, -1.33] at follow-ups closest to 6, 12, and 24 months, respectively. Explicitly targeting weight loss, men-only groups providing feedback and dietary goals were significantly associated with greater effectiveness (p < .05). CONCLUSIONS: Diet and physical activity interventions delivered in groups are effective in promoting clinically meaningful weight loss at 12 months. Intervention design and effectiveness vary considerably between studies, and evidence on what optimises the effectiveness of group-based weight-loss interventions remains limited. PMID- 29446542 TI - Novel calcitonin gene-related peptide/chitosan-strontium-calcium phosphate cement: Enhanced proliferation of human umbilical vein endothelial cells in vitro. AB - Bone cement materials have some disadvantages, including slow degradation and no biological activity, which greatly weakens their clinical application. Therefore, the search for a multifunctional bioactive bone cement has become urgent. In this study, a novel bone cement sample of calcitonin gene-related peptide (CGRP)/chitosan-strontium (Sr)-calcium phosphate cement (CPC) was developed. The structure and morphology were observed by scanning electron microscope (SEM). The cytotoxicity and proliferation of CGRP/chitosan-Sr-CPC were also measured. The expression of CGRP receptor 1 was measured using an immunofluorescence assay. Real-time polymerase chain reaction (PCR) and enzyme-linked immunosorbent assay (ELISA) were employed to quantify the VEGF mRNA and protein levels, respectively. Finally, the ability of the material to improve angiogenesis was assessed by using human umbilical vein endothelial cells (HUVECs) tube formation assay. The results showed that CGRP/Chitosan-Sr-CPC had the characteristics of a good orthopedic material without showing cell cytotoxicity to HUVECs. Meanwhile, CGRP/chitosan-Sr-CPC could release CGRP and enhance the proliferation of HUVECs via CGRP receptors. Moreover, CGRP/chitosan-Sr-CPC significantly upregulated the expression of the VEGF gene and protein in HUVECs, which might help improve the angiogenesis microenvironment. Besides, CGRP/chitosan-Sr-CPC could significantly improve angiogenesis of HUVECs. These findings provide new therapeutic material for the treatment of osteoporotic bone injury.

PMID- 29446543 TI - Cyclin dependent kinase inhibitor 2A/B gene deletions are markers of poor prognosis in Indian children with acute lymphoblastic leukemia. AB - BACKGROUND: Cyclin dependent kinase inhibitor 2A/B (CDKN2A/B) genes are implicated in many malignancies including acute lymphoblastic leukemia (ALL). These tumor suppressor genes, with a key regulatory role in cell cycle are located on chromosome 9p21.3. Previous studies involving CDKN2A/B gene deletions have shown mixed associations with survival outcome in childhood ALL. PROCEDURE: Hundred and four newly diagnosed children with ALL (1-14 years) were enrolled in this study. Genomic DNA from pretreatment bone marrow/peripheral blood samples of these children was investigated for copy number alterations in CDKN2A/B genes using multiplex ligation dependent probe amplification assay. Immunophenotype subtyping and cytogenetic and molecular analysis of ALL was performed at start of induction chemotherapy in all children. Children were monitored for response to prednisolone (Day 8), complete morphological remission, and minimal residual disease at the end of induction. The minimum postinduction follow-up period was 6 months. RESULTS: CDKN2A/B deletions were seen in 19.8% (18/91) of B lineage acute lymphoblastic leukemia (B-ALL) and 38.5% (5/13) of T lineage acute lymphoblastic leukemia (T-ALL). Monoallelic CDKN2A/B deletions were found in 61.1% of total deletions in B-ALL while all the children with T-ALL harbored biallelic deletions. The prevalence of CDKN2A/B gene deletions was found to be significantly higher in older children (P = 0.002), in those with higher leukocyte count (P = 0.037), and in National Cancer Institute high risk group patients (P = 0.001) in the B-ALL subgroup. Hazard ratio was significantly high for children with CDKN2A/B deletions in total cohort (P = 0.004). Children with CDKN2A/B deletion had significantly lesser event free survival (P = 0.03). CONCLUSIONS: CDKN2A/B deletions were significantly more prevalent in T-ALL subgroup and were found to have higher hazard ratio and lesser event free survival in total cohort in our study. PMID- 29446545 TI - From Aqueous Dispersions to Functional Materials: Capillarity and Electrostatic Adhesion. AB - The author was first acquainted with polymer lattices as model particles for studying sedimentation phenomena, evolving towards the elucidation of synthetic and natural latex heterogeneity and microchemistry. This brought new elements to understand the remarkable mechanical properties of natural rubber, leading to the latex route for making nanocomposites. These materials show exceptional properties that are largely due to electrostatic adhesion, a concept that had been previously presented by Deryagin but was later abandoned. Electrostatic adhesion is the outcome of ion partition and self-assembly within drying aqueous dispersions, producing co-existing domains with opposite charges. Their examination allowed several experimental observations leading to the proposal of mechanisms to explain hitherto challenging electrostatic phenomena shown by solids and liquids. Water plays a decisive role in all the different phenomena described in this account. PMID- 29446544 TI - Association between plasma trans-fatty acid concentrations and diabetes in a nationally representative sample of US adults. AB - BACKGROUND: A diet high in trans-fatty acids (TFA) induces insulin resistance in rodent models and primates. However, previous epidemiological studies on the association between TFAs, based primarily on self-reported intake from the diet, and diabetes in humans have yielded conflicting results. Herein we examined the associations of objectively measured plasma TFA concentrations with diabetes in a large population-based study among US adults. METHODS: We included 3801 participants aged >=20 years from the National Health and Nutrition Examination Survey 1999-2000 and 2009-10. Four major TFAs, namely palmitelaidic acid (C16:1 n 7t), elaidic acid (C18:1 n-9t), vaccenic acid (C18:1 n-7t), and linolelaidic acid (C18:2 n-6t, 9t), were measured in fasting plasma using gas chromatography-mass spectrometry. Diabetes was defined by self-reported physician diagnosis, plasma fasting glucose >=126 mg/dL, or HbA1c >=6.5%. RESULTS: After adjustment for other major risk factors, the odds ratios (95% confidence intervals) of diabetes comparing the highest with lowest quintile of plasma TFAs was 2.19 (1.27-3.79) for total TFAs (Ptrend = 0.01), 2.34 (1.48-3.72) for elaidic acid (Ptrend = 0.0004), 1.33 (0.82-2.15) for linolelaidic acid (Ptrend = 0.18), 1.58 (0.97 2.58) for palmitelaidic acid (Ptrend = 0.02), and 1.64 (0.95-2.84) for vaccenic acid (Ptrend = 0.08). In addition, total TFAs, elaidic acid, palmitelaidic acid, and vaccenic acid were significantly associated with fasting glucose, fasting insulin, the insulin resistance index, and HbA1c. CONCLUSIONS: In a nationally representative population, plasma TFAs, in particular elaidic acid, were positively associated with diabetes and biomarkers of glucose metabolism.

AB - Myelin Regulatory Factor (MYRF) is a transcription factor that has previously been associated with the control of the expression of myelin-related genes. However, it is highly expressed in human tissues and mouse embryonic tissues outside the nervous system such as the stomach, lung, and small intestine. It has not previously been reported as a cause of any Mendelian disease. We report here two males with Scimitar syndrome [MIM 106700], and other features including penoscrotal hypospadias, cryptorchidism, pulmonary hypoplasia, tracheal anomalies, congenital diaphragmatic hernia, cleft spleen, thymic involution, and thyroid fibrosis. Gross neurologic functioning appears to be within normal limits. In both individuals a de novo variant in MYRF was identified using exome sequencing. Neither variant is found in gnomAD. Heterozygous variants in MYRF should be considered in patients with variants of Scimitar syndrome and urogenital anomalies.

AB - Cu is a unique catalyst for CO2 electroreduction, since it can catalyze CO2 reduction to a series of hydrocarbons, alcohols, and carboxylic acids. Nevertheless, such Cu catalysts suffer from poor selectivity. High pressure of CO2 is considered to facilitate the activity and selectivity of CO2 reduction. Herein, a new strategy is presented for CO2 reduction with improved C2 H4 selectivity on a Cu catalyst by using CO2 capture materials as the support at ambient pressure. N-doped carbon (Nx C) was synthesized through high-temperature carbonization of melamine and l-lysine. We observed that the CO2 uptake capacity of Nx C depends on both the microporous area and the content of pyridinic N species, which can be controlled by the carbonization temperature (600-800 degrees C). The as-prepared CuO/Nx C catalysts exhibit a considerably higher C2 H4 faradaic efficiency (36 %) than CuO supported on XC-72 carbon black (19 %), or unsupported CuO (20 %). Moreover, there is a good linear relationship between the C2 H4 faradaic efficiency and CO2 uptake capacity of the supports for CuO. The local high CO2 concentration near Cu catalysts, created by CO2 capture materials, was proposed to increase the coverage of CO intermediate, which is favorable for the coupling of two CO units in the formation of C2 H4 . This study demonstrates that pairing Cu catalysts with CO2 capture supports is a promising approach for designing highly effective CO2 reduction electrocatalysts.

AB - This service evaluation analysed the long-term clinical outcomes, as measured by the Pain Self-Efficacy Questionnaire (PSEQ) and Oswestry Disability Index (ODI), of a 12-h group-based, multidisciplinary, combined physical and psychological treatment programme for patients with persistent back pain in a secondary care setting. Between April 2012 and December 2015, 373 patients attended the programme, with outcome measures obtained for 272 patients post-treatment. We randomly selected 120 patients who had completed treatment, for long-term outcome measurement follow-up, and gained outcome measures for 40 patients in total. At a median follow-up of 27 months post-treatment, the results demonstrated significant improvements in both clinical outcome measures. We conclude that a brief combined physical and psychological treatment programme appears to be effective at reducing back disability and pain self-efficacy, with improvements maintained in the longer term.

AB - The ability to introduce a nitrile group into a biologically active compound is very useful in organic synthesis, owing to the importance of nitrile groups in transformations and tuning molecular properties. To date, nucleophilic cyanation has been the most used strategy for this purpose, whilst electrophilic cyanation reactions are less developed. Recently, the electrophilic cyanation reagent N cyano-N-phenyl-p-toluenesulfonamide (NCTS) has received increasing attention, owing to its superior properties in terms of safety and practicality. This Focus Review summarizes recent progress in transition-metal-catalyzed cyanation reactions that use NCTS. PMID- 29446550 TI - Impact of workplace violence against nurses' thriving at work, job satisfaction and turnover intention: A cross-sectional study. AB - AIMS AND OBJECTIVES: To investigate the interrelationships between workplace violence, thriving at work and turnover intention among Chinese nurses and to explore the action mechanism among these variables. BACKGROUND: Workplace violence is a dangerous occupational hazard globally, and it is pervasive in the health service industry. As a corollary, workplace violence may produce many negative outcomes among nursing staff. Consequently, it hinders nurses' professional performance and reduces nursing quality. DESIGN: A cross-sectional online survey was conducted. METHODS: A total of 1,024 nurses from 26 cities in China were recruited from February-May 2016. An anonymous questionnaire was used in this survey. Participants' completed data were collected using a demographics form and a 26-item questionnaire consisting of scales addressing workplace violence, thriving at work, job satisfaction, subjective well-being and turnover intention. To evaluate multivariate relationships, some multiple linear hierarchical regression analyses were performed. RESULTS: Workplace violence significantly negatively influenced nurses' job satisfaction and thriving at work, and significantly positively influenced nurses' turnover intention. Job satisfaction significantly predicted thriving at work and turnover intention. Job satisfaction not only fully mediated the relationship between workplace violence and thriving at work, but also partially mediated the relationship between workplace violence and turnover intention. Subjective well-being moderated the relationship between workplace violence and job satisfaction and the relationship between workplace violence and nurses' turnover intention. CONCLUSIONS: Adverse effects of workplace violence were demonstrated in this study. Decreases in job satisfaction were a vital mediating factor. The moderating effect of subjective well-being was helpful in reducing the harm of workplace violence to nurses and in decreasing their turnover intention. RELEVANCE TO CLINICAL PRACTICE: Workplace violence and its negative impact on nursing work should not go unnoticed by nursing managers. Nurses' subjective well-being is critical in controlling and mitigating the adverse effects of workplace violence.

However, there is a paucity of methods capable of quantifying the dynamics of guest binding processes. Here, we demonstrate nanopore detection of single-molecule binding within metallosupramolecular cages. Real-time monitoring of the ion current flowing through a transmembrane alpha-hemolysin nanopore resolved the binding of different guests to both cage enantiomers. This enabled the single molecule kinetics of guest binding to be quantified, whereas the ordering and durations of events were consistent with a guest-exchange mechanism that does not involve ligand dissociation. In addition to providing a new approach for single molecule interrogation of dynamic supramolecular processes, this work also establishes that cage complexes which are too large to enter the nanopore can be exploited for detecting small molecules, thus constituting a new class of molecular adapter. PMID- 29446551 TI - Targeting Murine Mesenchymal Stem Cells to Kidney Injury Molecule-1 Improves Their Therapeutic Efficacy in Chronic Ischemic Kidney Injury. AB - Mesenchymal stem cells (MSC) have been experimentally used for kidney repair, but modest retention limits their efficacy. Cell-surface coating allows modulating MSC homing and interaction with target cells. We coated mouse adipose tissue derived MSC with antibodies directed against kidney injury molecule-1 (ab-KIM1), which is upregulated in injured kidneys, and tested the hypothesis that this would enhance their therapeutic effects in ischemic kidney injury. Untreated MSC, ab-KIM1-coated MSC (KIM-MSC), or vehicle, were injected systemically into the carotid artery of 2-kidneys, 1-clip mice 2 weeks after surgery. MSC retention in different organs was explored 24 hours, 48 hours, or 2 weeks after injection. Renal volume, perfusion, and oxygenation were studied 2 weeks after injection using magnetic resonance imaging in vivo, and renal inflammation, apoptosis, capillary density, and fibrosis ex vivo. The ab-KIM1 coating had little effect on MSC viability or proliferation. The stenotic kidney showed upregulated KIM1 expression, selective homing, and greater retention of KIM-MSC compared to untreated MSC and compared to other organs. KIM-MSC-injected mice improved renal perfusion and capillary density, and attenuated oxidative damage, apoptosis, and fibrosis compared to mice treated with vehicle or with native MSC. In conclusion, MSC coating with ab-KIM1 increased their retention in the ischemic kidney and enhanced their therapeutic efficacy. This novel method may be useful to selectively target injured kidneys, and supports further development of strategies to enhance cell-based treatment of ischemic kidney injury.

AB - The experiences of children related to conflict and crisis management in child mental health settings, especially those aged 12 and below, have been rarely studied. This study examined the moral experiences of children related to conflict and crisis management and the related use of restraint and seclusion in a child mental health setting. A 5-month focused ethnography using a participatory hermeneutic framework was conducted in a day hospital programme for children with severe disruptive disorders within a mental health institute. Children considered restraints and seclusion could help them feel safe in certain instances, for example if another child was being aggressive towards them or in exceptional cases to prevent self-injury. However, their own experiences of being restrained were predominantly negative, especially if not knowing the reason for their use, which they then found unfair. Some of the children emphasized the punitive nature of the use of restraints and seclusion, and most children disagreed with these practices when used as a punishment. Children's perspectives also highlighted the limits of the use of a uniform de-escalation approach by the staff to manage crises. Children considered discussing with the staff and developing a relationship with them as more helpful in case of a crisis then the use of a de-escalation approach or coercive strategies. PMID- 29446555 TI - Ge14 Br8 (PEt3 )4 : A Subhalide Cluster of Germanium. AB - Heating a metastable solution of GeI Br to room temperature led to the first structurally characterized metalloid subhalide cluster Ge14 Br8 (PEt3 )4 (1). Furthermore 1 can be seen as the first isolated binary halide cluster on the way from GeI Br to elemental germanium, giving insight into the complex reaction mechanism of its disproportionation reaction. Quantum chemical calculations further indicate that a classical bonding situation is realized within 1 and that the last step of the formation of 1 might include the trapping of GeBr2 units. PMID- 29446554 TI - Impact of cigarette smoking on the relationship between body mass index and insulin: Longitudinal observation from the Bogalusa Heart Study. AB - OBJECTIVES: Despite the inverse association between cigarette smoking and body mass index (BMI), it is unknown whether the effect of smoking on insulin is mediated through decreased BMI. This study aims to examine the temporal relationship between BMI and insulin, the impact of smoking on this relationship and the mediation effect of BMI on the association between smoking and insulin levels. METHODS: The longitudinal cohort consisted of 1121 adults (807 white and 314 black participants, mean age, 42.0 years at follow-up) for whom BMI and fasting insulin were measured twice, with an average follow-up period of 17.1 years. Cross-lagged panel and mediation analysis models were used to examine the temporal relationship between BMI and insulin, and the mediation effect of BMI on the smoking-insulin association. RESULTS: Smoking was inversely associated with insulin (regression coefficient, -0.073; P = .015 at baseline and -0.121; P < .001 at follow-up), adjusting for age, race and gender. After additional adjustment for follow-up periods, the cross-lagged path coefficient from BMI to insulin (beta, 0.226; P < .001) was significantly greater than that from insulin to BMI (beta, -0.029; P = .208), with P < .001 for the difference. The path coefficient from BMI to insulin was significantly greater in non-smokers (beta, 0.273; P < .001) than in smokers (beta, 0.122; P = .046), with P = .013 for the difference. The mediation effect of BMI on the smoking-insulin association was estimated at 53.4% (P = .030) at baseline and 58.7% (P < .001) at follow-up. CONCLUSIONS: These findings suggest that cigarette smoking has a significant impact on the one-directional relationship from BMI to insulin. The insulin lowering effect of smoking is predominantly mediated through decreased BMI as the result of smoking. PMID- 29446556 TI - The origins and early elaboration of projectile technology. AB - The ability of Homo sapiens to kill prey at a distance is arguably one of the catalysts for our current ecological dominance. Many researchers have suggested its origins lie in the African Middle Stone Age or the European Middle Palaeolithic (~300-30 thousand years ago), but the perishable components of armatures rarely preserve. Most research on this subject therefore emphasises analysis of armature tip size, shape, and diagnostic impacts or residues. Other lines of evidence have included human skeletal anatomy or analyses of the species composition of faunal assemblages. Projectile Impact Marks (PIMs) on archaeofaunal remains offer an ideal complement to this work, but their potential has been restricted mainly to the later Eurasian zooarchaeological record. A review of current evidence and approaches shows that systematic PIM research could add much to our understanding of early projectile technology, especially in Africa.

AB - The Acheulean handaxe is one of the longest-known and longest-surviving artifacts of the Palaeolithic and, despite its experimentally tested functionality, is often regarded as puzzling. It is unnecessary to invoke a unique-for-mammals genetic mechanism to explain the handaxe phenomenon. Instead, we propose that two nongenetic processes are sufficient. The first is a set of ergonomic design principles linked to the production of sturdy, hand-held cutting tools in the context of a knapped-stone technology that lacked hafting. The second is an esthetic preference for regular forms with gradual curves and pleasing proportions. Neither process is a cultural meme but, operating together in a cultural context, they can account for all of the supposedly puzzling time-space patterns presented by handaxes. PMID- 29446560 TI - Less of a bird's song than a hard rock ensemble. AB - Corbey et al. (2016) propose that the Acheulean handaxe was, at least in part, under genetic control. An alternative perspective is offered here, focusing on the nature of the Acheulean handaxe and the archaeological record, and re emphasizing their status as cultural artefacts. This is based on four main arguments challenging the proposals of Corbey et al. Firstly, handaxes do not have to track environmental variation to be a cultural artefact, given their role as a hand-held butchery knife or multi-purpose tool. Secondly, while handaxe shapes do cluster around a basic bauplan, there is also significant variability in the Acheulean handaxe record, characterized by site-specific modal forms and locally expressed, short-lived, idiosyncratic traits. Critically, this variability occurs in both time and space, is multi-scalar, and does not appear to be under genetic control. Thirdly, handaxes were produced in social contexts, within which their makers grew up exposed to the sights and sounds of artefact manufacture. Finally, the localized absences of handaxes at different times and places in the Lower Paleolithic world is suggestive of active behavioral choices and population dynamics rather than genetic controls.

AB - In this contribution, we address a major puzzle in the evolution of human material culture: If maturing individuals just learn their parental generation's material culture, then what is the origin of key innovations as documented in the archeological record? We approach this question by coupling a life-history model of the costs and benefits of experimentation with a niche-construction perspective. Niche-construction theory suggests that the behavior of organisms and their modification of the world around them have important evolutionary ramifications by altering developmental settings and selection pressures. Part of Homo sapiens' niche is the active provisioning of children with play objects - sometimes functional miniatures of adult tools - and the encouragement of object play, such as playful knapping with stones. Our model suggests that salient material culture innovation may occur or be primed in a late childhood or adolescence sweet spot when cognitive and physical abilities are sufficiently mature but before the full onset of the concerns and costs associated with reproduction. We evaluate the model against a series of archeological cases and make suggestions for future research. PMID- 29446563 TI - The Evolution of Evolutionary Anthropology.

AB - Trypanosoma cruzi, the causative agent of Chagas disease, interacts with molecules in the midgut of its insect vector to multiply and reach the infective stage. Many studies suggest that the parasite binds to midgut-specific glycans. We identified several glycoproteins expressed in the intestine and perimicrovillar membrane (PMM) of Triatoma (Meccus) pallidipennis under different feeding conditions. In order to assess changes in protein-linked glycans, we performed lectin and immunoblot analyses on glycoprotein extracts from these intestinal tissues using well-characterized lectins, and an antibody, which collectively recognize a wide range of different glycans epitopes. We observed that the amount and composition of proteins and glycoproteins associated with different glycans structures changed over time in the intestines and PMM under different physiological conditions. PMM extracts contained a wide variety of glycoproteins with different sugar residues, including abundant high-mannose and complex sialylated glycans. We propose that these molecules could be involved in the process of parasite-vector interactions. PMID- 29446566 TI - Celebrating milestones and balancing metrics. PMID- 29446565 TI - Targeted surgical parathyroidectomy in end-stage renal disease patients and long term metabolic control: A single-center experience in the current era. AB - BACKGROUND: The long-term results of surgical parathyroidectomy (PTX) in end stage renal disease (ESRD) patients are less well known in the modern era of newer activated vitamin-D analogs, calcimimetics and intraoperative monitoring of parathyroid hormone (PTH). METHODS: We performed a retrospective chart review of all ESRD patients undergoing PTX at the University of Mississippi Medical Center between January 2005 and August 2011, with follow-up data as available up to 4 years. All PTXs were performed with intraoperative second-generation PTH monitoring and targeted gland size reduction. RESULTS: The cohort (N = 37) was relatively young with a mean (+/-SD) age of 48.4 +/- 13.9. 94.6% of the subjects were African American and 59.5% female. Preoperatively, 45.9% received cinacalcet (CNC) at a mean dose of 63.5 +/- 20.9 mg. The size of the largest removed glands measured 1.7 +/- 0.8 cm and almost all (94.6%) glands had hyperplasia on histology. The mean length of inpatient stay was 5.5 +/- 2.4 days. Preoperative calcium/phosphorus measured 9.6 +/- 1.2/6.6 +/- 1.7 mg/dL with PTH concentrations of 1589 +/- 827 pg/mL. Postoperative PTH values measured 145.4 +/- 119.2 pg/mL. Preoperative PTH strongly correlated (P < 0.0001) with both alkaline phosphatase (ALP) levels (r: 0.596) and the number of inpatient days (r: 0.545), but not with CNC administration. Independent predictors for the duration of hospitalization were preoperative ALP (beta 0.469; P = 0.001) and age (beta -0.401; P = 0.005) (R2 0.45); for postoperative hypocalcemia, age (beta: -0.321; P = 0.006) and preoperative PTH (beta: 0.431; P = 0.036) were significant in linear regression models with stepwise selection. CONCLUSION: Gland-sparing PTX achieved acceptable control of ESRD-associated hyperparathyroidism in most patients from a socioeconomically challenged, underserved population of the United States. PMID- 29446567 TI - Prognostic value of the index of microcirculatory resistance after percutaneous coronary intervention in patients with non-ST-segment elevation acute coronary syndrome. AB - BACKGROUND: The prognostic value of physiological indices in non-ST-segment elevation acute coronary syndrome (NSTE-ACS) patients undergoing percutaneous coronary intervention (PCI) is unknown. We investigated the prognostic efficacy of physiological indices obtained after PCI in patients with NSTE-ACS. METHODS: Eighty-three patients (men: n = 70, age: 63.7 +/- 9.7 years) undergoing PCI for NSTE-ACS within 48 hr postadmission were investigated. Fractional flow reserve (FFR), coronary flow reserve (CFR), and the index of microcirculatory resistance (IMR) of the culprit vessels were measured after the completion of PCI. The patients were clinically followed up to determine major cardiac adverse events (MACE), including death, congestive heart failure requiring hospitalization, and remote coronary revascularization. RESULTS: The median FFR, CFR, and IMR values were 0.90 (interquartile range [IQR] 0.86-0.95), 2.38 (IQR 1.75-4.17), and 22.9 (IQR 11.2-31.5), respectively. During a median follow-up of 20.7 months, 19 MACEs (22.9%) were documented. No significant difference in baseline patient characteristics, except for age, was detected between patients with and without MACE. Patients with MACE showed higher IMR and lower CFR than those without (IMR: 27.2 vs. 16.3; P = 0.001, CFR: 1.82 vs. 2.55; P = 0.04), whereas FFR was not significantly different (0.92 vs. 0.89; P = 0.72), irrespective of the MACE occurrence. Post-PCI IMR was the only independent predictor of MACE (hazard ratio 1.033, 95% confidence interval 1.013-1.052, P = 0.001). The MACE-free survival was significantly worse in patients with high post-PCI IMR (chi2 7.12; P = 0.008). CONCLUSION: Post-PCI IMR may help identify patients at high risk for subsequent adverse coronary events who require adjunctive therapeutic strategies.

AB - Clinical genome and exome sequencing (CGES) may identify variants leading to targeted management of existing conditions. Yet, CGES often fails to identify pathogenic diagnostic variants and introduces uncertainties by detecting variants of uncertain significance (VUS) and secondary findings. This study investigated how families understand findings and adjust their perspectives on CGES. As part of NIH's Clinical Sequencing Exploratory Research Consortium, children were recruited from clinics at the Children's Hospital of Pennsylvania (CHOP) and offered exome sequencing. Primary pathogenic and possibly pathogenic, and some secondary findings were returned. Investigators digitally recorded results disclosure sessions and conducted 3-month follow up interviews with 10 adolescents and a parent. An interdisciplinary team coded all transcripts. Participants were initially disappointed with findings, yet reactions evolved within disclosure sessions and at 3-month interviews toward acceptance and satisfaction. Families erroneously expected, and prepared extensively, to learn about risk for common conditions. During disclosure sessions, parents and adolescents varied in how they monitored and responded to each others reactions. Several misinterpreted, or overestimated, the utility of findings to attribute meaning and achieve closure for the CGES experience. Participants perceived testing as an opportunity to improve disease management despite results that did not introduce new treatments or diagnoses. Future research may examine whether families experience cognitive dissonance regarding discrepancies between expectations and findings, and how protective buffering minimizes the burden of disappointment on loved ones. As CGES is increasingly integrated into clinical care providers must contend with tempering family expectations and interpretations of findings while managing complex medical care.

AB - The dynamics and structure of the occupational morbidity rate in main branches of the industry in the Eastern Siberia for the 2000-2015 (on the example of the Irkutsk region) is presented in this paper. During the observation period there were noted the significant gain in the number of cases of occupational diseases registered in such different branches of industry as Coal and Lignite Mining, ship and aircraft building, and in some other branches (metallurgical production, air transport, pulp production, electric power distribution industry). In the structure of the occupational morbidity leading positions are occupied by diseases associated with the exposure to physical factors, industrial aerosols, physical overload and overexertion of certain organs and systems. The main reasons and factors contributing to the gain of the occupational morbidity rate are the imperfection of technological processes, working places, personal protective equipment and/or their lack, constructive defects of machines and equipment, the violation of safety regulations, regimen of the work and rest, insufficiently high level of medical and preventive maintenance, delayed making of decisions for the rational employment to the workers with the revealed early forms of occupational diseases. There pointed out priority directions of the prevention the implementation of which will allow to decline the level of the occupational morbidity rate. The main directions are the implementation of economically caused mechanisms of the interest in the preservation of workers ' health; implementation of the regional aimed programs; the introduction of new processes, equipment and mechanisms meeting modern hygienic requirements; the assessment of occupational risk with the creation and implementation of the system of monitoring for the dynamics of working conditions and the state of the workers ' health for the making corrective management solutions on the optimization and elevation of the efficacy and relevance of developed and implemented preventive health measures.

The analysis of the etiological role of occupational factors in the shaping of the morbidity and the physiological and clinical manifestations, established indices of the risk for occupational and industrial caused pathology have allowed to substantiate the relationship of a number of nosological forms associated with working conditions of firefighters. There was developed a system of preventive activities for the promotion and preservation of the health of firefighters, as well as a conceptual model for monitoring of working conditions and state of health.

AB - The hygienic assessment of working conditions of employees exposed to local vibration established that working conditions for employees ofvibration dangerous occupations at the aircraft plant according to the degree from a health standpoint and hazard are referred to the fourth (dangerous) class of the degree of danger that stipulates stable high levels of the morbidity rate. The leading factor is a local vibration that results in the consistently high levels of occupational morbidity rate. There was shown the efficiency of the use of the pulsed magnetic stimulation in the treatment ofpatients with vibration disease associated with the exposure to local vibration. For the evaluation of the effectiveness of treatment in patients the condition of the central nervous system was determined with the use of computer electroencephalography with the registration of visual and auditory evoked potentials and somatosensory evoked potentials; there was studied the state of the peripheral nerves in arms and legs relying upom electromyographic data; there was performed psychological study. After the performance of pulse magnetic stimulation in patients diagnosed to have the vibration diseases there were observed the improvement in the interaction of cortical-subcortical structures and associative areas of the frontal and temporal lobes of the brain. After treatment there was noted the shortening of the time of the conduction of the afferent wave of the excitation at the level of the cervical spinal cord, subcortical structures and the central conduction time. There was restored previously reduced the speed of the conduction of the impulse via the distal parts of the tibial and median nerve, through the ulnar nerve in the area of the elbow joint. There was noted the rise in the average temperature on the hands; the decline of thresholds of vibration and pain sensitivity; the improvement of indices characterizing of the state of mnestic- attentional and psycho-emotional scope of activity.

AB - The transition to a new stage of the development - the information society is an objective reality and has an influence on all areas of the activity of the society, including the establishment of a child as an object of the hygienic research. In conditions of the general informatization of the society, the appearance of so-called "clip thinking," explains the maladjustment of educational technologies to mechanisms of children ' and teenagers 'perception and is confirmed by the growth of the school pathology and the gain in the morbidity rate. In the investigation on the example of the educational institutions of Irkutsk it was executed the evaluation of the impact of the intensification of informatization of education and personal development. For the investigation there were formed 2 groups ofpreschools with different levels of informatization in the same preschool institution of the central district of the city of Irkutsk but in different periods of time. In total there were observed 211 children aged of 5.5 to 6.5 years. For the study the influence of the intensification (and informatization of training there were formed 2 groups of small schoolchildren with different levels of intensification (and informatization) of education. The total number of cases accountedfor 465 children aged of 7-9 years. There were suggested methodical approaches to the estimation of the health status of the children, with taking into account the inevitable influence offactors of informatization and the intensification of education. The performed investigations have allowed to reveal the following tendencies in the shaping of the psychophysical state of health and development of children: an increase of level of informatization of education and personal and accomplishment; intensification of learning working; reduction of the attention level; imagination and visual divergence; capability to the linear differentiation and construction of inferences; fear to fail to meet the expectations of surrounding people and low resistance to stress; the increase speed of data processing along with fall in quality; the gain in hyperactivity.

AB - The purpose of the research is to assess the intra-environment indices in urban and rural secondary schools. In the course of special studies there was given the hygienic assessment of the climate, illumination and air quality of classrooms. In classrooms in rural schools microclimate indices were established to fail to meet hygienic requirements mainly on the temperature and humidity parameters. In rural schools, the temperature was decreased to 16-17 degrees C in 19.0 +/- 8.6% of classrooms, humidity was elevated to 63.1% in 25.7 +/- 7.4% of classrooms. Among urban schools the humidity in 49.6 +/- 4.4% of classrooms reduced to 23.3 +/- 0.3%, in 20.8 +/- 5.4% of offices it was increased to 71.9 +/- 0.9%. The coefficient of the natural illumination in rural schools has been reduced to 0.86 1.4% in 33.9 +/- 14.2% of classrooms. In 25.1 +/- 2.3% of classrooms in urban schools the level of natural light ratio was below the normative values and varied in the range of 0.32-1.3%. It is noted that in the offices of informatics natural light indices are significantly lower than in the classrooms for core subjects. The artificial lighting in urban schools was found to be lower than hygienic standards on the desks by 1.9 times, 2.2 times - at the board. There were obtained statistically significant handshaking health problems of urban schoolchildren due to intraenvironmental factors. The c dimate in surveyed gyms in rural schools is different in the low temperature and high humidity. The hygienic assessment of the air pollution classrooms' medium was executed for a range of chemicals: formaldehyde, carbon monoxide, nitrogen dioxide, sulfur dioxide, particulate matter. Concentrations of formaldehyde; nitrogen dioxide, suspended solids in the air in classrooms in urban schools appeared to be higher than in rural schools. Carbon monoxide concentrations in classrooms in rural schools was found to exceed their values in urban schools. The air in classrooms of the one of the cities was found to be differed by a specific atmosphere for its chemical - hydrogen fluoride, in concentrations exceeding the maximum allowed concentration by 3-3.5 times.

AB - The article considers the findings of hygienic assessments of educational conditions in urban and rural schools in Mongolia and socio-economic conditions of living of schoolchildren and analysis of anthropometric measurements of schoolchildren aged of 7-16 years in relation to the assessment of harmonicity of their physical development. Hygienic conditions in Mongolian schools are characterized by improper organization of the educational - accomplishment process, high occupancy rate in classes causing insufficient space for a pupil and disconformity of school furniture parameters of school desks and chairs to growth and age requirements of pupils. Comparative assessment of socio-economic factors revealed (videleno avtorom) that the majority (84.1%) of rural pupils reside in uncomfortable houses and gerdwellings, 58.5 % - in large families with many children, 46.3 % - in families with poor living conditions. There were obtained data about differences in physical development of urban and rural schoolchildren pronounced with age by the gain in the number of children with disharmonious development and children with lower physical indices of the development, delayed by 1-2 years appearance of the crossing of growth and growth shift typical for rural children in comparison with their urban counterparts. According to results of multivariate regression analysis most significant factors for the formation of physical development of school children in descending order are academic workload, the place of residence, the number of children in the family, uncomfortable living conditions, household income and parent's education. In the presence of these factors, the risk of the formation of disharmonious physical growth of school children increases by 1.8-2.8 times. The probability of the risk offormation of disharmonious physical development of schoolchildren living in rural areas was found to be by 2.5 times more than for their urban counterparts. The results can be usedfor scientific substantiation and development of targeted health measures.

AB - The article presents results of study of the impact of iodine deficiency and technogenic fluoride on the state of the thyroid gland in children. On the example of two districts of the city of Bratsk there were executed dynamic investigations (2002 and 2012), including the estimation of the pollution of ambient air and soil by fluorine compounds, levels of iodine intake by the body, the clinical examination of children aged from 5 to 7 years d and interviewing of their parents. In the course of the medical examination there were executed: physical examination by the pediatrician, endocrinologist, ultrasound examination of the thyroid gland, the determination both of serum hormone content by radioimmunoassay and urinary excretion offluorine and iodine. Concentrations of hydrogen fluoride and a solidfluorides in ambient air led to the accumulation offluoride ion in the soil. The iodine entering with drinking water and food, was established to provide only 37.5-50% of the daily requirement of iodine. Increased fluoride ion content in urine and milk teeth in children is associated with the concentrations of the fluorine-containing pollutants in the ambient air and soil. The fluoride pollution against the background of the natural iodine deficiency was established to increase the frequency of functional and morphological disorders of the thyroid gland in children. PMID- 29446581 TI - Odontogenic focal infection is a possible trigger of severe Henoch-Schonlein purpura nephritis. PMID- 29446580 TI - Is there any difference between the symptomatology and clinical findings of viral agents causing dehydration? AB - BACKGROUND: Acute gastroenteritis is responsible for dehydration in many children. The viruses like rotavirus, norovirus, and adenovirus are considered the main causative agents of gastroenteritis. The goal of this study is the evaluation of the symptoms, clinical findings and hospitalization requirements in pediatric patients with dehydration secondary to viral gastroenteritis. METHODS: The distribution of age, symptoms, clinical and laboratory findings and hospitalization requirements of 156 viral acute gastroenteritis patients with moderate dehydration were evaluated retrospectively. Patients were between 3 months to 16 years of age (mean: 38.7 months). The patients were categorized into four groups according to etiological agents as rotavirus, norovirus, adenovirus, and mixed infections for the comparison of symptoms, clinical characteristics, laboratory results, seasonal distribution, treatment requirements, hospitalization unit, and hospitalization period. Age groups were categorized as 0-24 months, 25-72 months, and >72 months. Clinical characteristics of patients were analyzed for hospitalization period as <24 hours, and >=24 hours. RESULTS: Moderate-degree dehydration was detected in 156 patients with acute gastroenteritis (156/278) caused by rotavirus (60.5%), norovirus (58%) and adenovirus (42%) respectively. The common symptoms of all patients were vomiting, diarrhea, abdominal pain and malaise, although fever was seen mostly in the patients of rotavirus. Aspartat aminotransferase (AST) was elevated in rotavirus gastroenteritis (11.5%) more than norovirus (5.4%) and adenovirus (0.8%) infections. Elevated blood urea nitrogen (BUN) levels (>20 mg/dL) were shown in 79.3%, of patients especially in rotavirus (43.8%). CONCLUSIONS: The main agents of acute gastroenteritis which caused dehydration were norovirus and rotavirus in our patients. Rotavirus was detected in most of the hospitalized patients with severe symptoms. AST was prominently elevated in rotavirus gastroenteritis. The clinical characteristics and some laboratory findings including hyperglycemia, leukocytosis, and elevated AST may be helpful in differentiating rotavirus from norovirus gastroenteritis. BUN level was insignificantly elevated in patients with rotavirus. PMID- 29446582 TI - What is hindering research on psychological aspects of fathers of premature infants? PMID- 29446583 TI - [Determination of priority unfavorable environmental factors]. AB - In the Irkutsk region there are recorded high indices of rates of morbidity, disability, mortality rate of the working-age population and low levels of life expectancy of the population, that is confirmed by ranking position levels among the all subjects of the Russian Federation. According to all mentioned indices of health the region is inside the top ten unfavorable regions of Russia. In relation to the problem in the state of health of the adult population the estimation of the causal relationships between environmental factors and certain health indices is actual. The list of studiedfactors included health indices that characterize the harmful working conditions of the working population and basic socioeconomic indices in the region. Estimation of causal-relationship relationships was performed with the use of methods of multivariate analysis - correlation and multiple linear regression. In the selection offactors for the construction of mathematical models of multiple regression there were used methods of the analysis of variables variability, pair correlation coefficients matrix and sequential switching covariates to eliminate the problems of multicollinearity, pre-standardization of indices for the elevation of the numerical stability of regression analysis algorithm. As a result of the execution of the analysis there were constructed statistical models for the dependence in the system variables "environment - public health", which allowed to identify the most informative regression models for the adult population health according to indices of primary disability of the population, the mortality rate and life expectancy of the working age population. According to results of the analysis there were identified priority factors affecting on the health of the adult population of the Irkutsk region. To these factors there are referred the proportion of workplaces failing to meet sanitary standards for vibration and 8 socio-economic indices of living standards of the population.

AB - There are presented results of the immunohistochemical study of neural tissue of outbred albino rats exposed for 9 days to the influence of the silver nanobiocomposite consisted of silver nanoparticles encapsulated into a matrix of a natural polymer - arabinogalactan. The research of albino rats was performed in 2 stages: half of the rats in each groups were decapitated immediately after the exposure (early period) and the rest animals - 6 months after the end of exposure (remote period). The impact of the studied substance was proved to cause functional changes in cells of the nervous tissue. After the subacute administration of the nanobiocomposite - argentum-arabinogalactan (nano-Ag-AG) in cells of the nervous tissue of the brain of albino rats the expression of apoptotic and anti-apoptotic protein (caspase-3 and bcl-2) was established to be changed. The number of normal neurons producing protein caspase-3 sharply increases. Herewith the number of immunonegative neurons fairly declines. Along with this there is noted the high level of bcl-2 content, one function ofwhich is the preclusion ofapoptosis. In preparations there is revealed a significant gain in the number of bcl-2 expressing neurons, however, the protective effect of the protein is not fully realized, that leads to the significantly increase in the content of damaged hyperchromatic cells. The evaluation of results of the immunohistochemical study of the nervous tissue of albino rats according to data concerning the proteins caspase-3 and bcl-2 expression permits to make a conclusion about the capability of nanoargentum encapsulated into polymer matrix by passing the blood-brain barrier to induce the triggering apoptosis cascade in neurons of the cerebral cortex.

AB - Among the risk factors that have priority in shaping the health of the population, a leading place is held by a rational nutrition. Presented results indicate to the absence of a stable group eating regularly, with the rational regularity and having all the necessary meals and the recommended food set. In the population of the adult people of the city of Irkutsk there is revealed the role of the nutritional factor in the formation of morbidity rate level of the adult population. It was found that the risk of diseases of the circulatory system accounted of 2.5 (95% CI: 2.1-3.6), for infectious and parasitic diseases 2.4 (95% CI: 1.7-3.5), for the endocrine system - 2.2 (95% CI: 1.4-3.4), andfor the urinary system - 2.3 (95% CI: 1,7-3,0).

It considers a variety of brain activity parameters to determine the type of mental operation being performed at the moment. The corresponding algorithm previously developed in the lab was modified for real-time application. The possibility of interface application for cognitive skills training was investigated. In the proposed paradigm, as soon as the EEG spectral pattern was adequate for the current task, some clue to the solution was presented. As we supposed, such positive biofeedback should facilitate memorization of the current brain state. After just one learning session, the differences in EEG spectra, corresponding two types of tasks, were concentrated in more narrow frequency ranges. It indicates the decrease of mental effort. Moreover, the majority of subjects succeeded to solve the tasks faster, that's an evidence of efficiency increased. The developed interface could be used for the new type of training, based on objective features of brain activity.

PMID- 29446588 TI - [Hygiene and the spectral energtic light pattern]. AB - There are considered methodological bases of multicriteria synthesis of a spectral energetic pattern for the evaluation of the excessive share of blue and red light in the spectrum of artificial energy sources. The basis of this methodology is relied upon on the hygienic approach to the spectrum analysis of solar and led light. Relying upon on "photobiological paradox of vision" according to M. A. Ostrovsky, conditions of "melanopsin cross" and mechanisms of adverse impact of light on vision, all the spectral-energy characteristics of solar light were divided into subspaces. The border between them became a spectral energy pattern for the evaluation of artificial sources on the security of their impact on eye and human health according to criteria of the excessive dose of blue or red light. On two examples there was shown the effectiveness and clarity of this estimation with the using of the spectral energetic pattern of light. PMID- 29446589 TI - [The approach to the regulation of mercury according to the content of its termoforms in soils and bed loads]. AB - The article contains the results of the ecological and hygienic diagnostics of conditions of lands of areas of different sizes and varying degrees of urbanization, located in different agro-climatic conditions of European Russia (the southern Astrakhan region, he city of Moscow). Assessments of the state of territories use a new approach to rationing of Hg according to quantitative ratios of the content of its thermoforms in soils, grounds and alluvium (in litho substrate). The method of diagnostics is based on known properties of Hg forms: their geochemical activity (migration mobility) and toxicity decline along with the increment of the Hg temperature threshold of the release in the process of continuous warming up of the litho substrate sample (up to 1100 degrees C). Thermoforms are not tied to specific minerals or chemicals and are conditionally designated as FR (Free: <180 degrees C), CL (Chloride: 180-250 degrees C), FS and CS (physically and chemically sorbed: 250-400 degrees C), SU (Sulfide: 400-500 degrees C) IS (isomorphic: >500 degrees C) Hg forms. Among forms, also conditionally according to complexes of low, medium and high temperature variations(FR + CL, FS + CS and SU + IZ, respectively, there are selected groups of "mobile", "sustainable" and "inert" forms. For technogenic Hg there is characterized the predominance in the sample of "mobile" and to lesser extent degree - "stable" thermoforms. The more intensive this predominance is, the higher is environmental hazard. The natural accumulation is diagnosed by the presence and prevalence of the sum of moderate - and high-temperature inert forms of Hg. According to the ratios of Hg content, its forms and groups, as well as the density of correlationships between them, 6 indices of the conditions of soils and alluvium were developed by ourselves.Main coefficients out of indices on informativeness of results of diagnostics are the following factors: Endogenous input, Geochemical activity and Hg mobility. With regard to the combination of variability in indices, the total amount of Hg, the genesis and intensity of its accumulation (natural or anthropogenic), there were also developed ranking scales of the ecological and hygienic condition of the land areas and surface water bodies. As a result, on the base of such approach to the regulation of Hg the information value of assessments of mercury contamination of land significantly increased. At the objects of assessments there were identified following areas: foci of the manifestation of Hg hypolimnetic emanations on the landscape surface - dispersion halos in the areas of the Earth crust fracture (the dome of the Astrakhan gas condensate field); environmentally dangerous (sometimes even at a low total content of Hg) parts of cities, towns, their districts, as well as beds of watercourses and water reservoirs bottom (the Volga river valley and delta, the Lefortovo quarter in Moscow). There was also diagnosed the threshold of the background distribution of gross Hg content detected = 0.2-0.3 mg/kg. Its magnitude is consistent with domestic and abroad safe levels of Hg accumulation in soils = 0.3-0.4 mg/kg. The approach provides the differentiation of the environmental hazard lands. Technology of the approach can be used in the development of normative Document for the diagnosis of environmental and sanitary condition of territories in the system of Classifications of hazard of waste, in decontamination of territories, water areas and land zoning according to the criteria of natural or anthropogenic Hg accumulation.

AB - At present due to the environmental contamination by heavy metals there is a great interest to investigate the processes of their both accumulation in plants and toxic effect on biochemical indices. Therefore the objective of this research was the analysis of the alteration of the system of antioxidant protection ofplants in conditions of soil contamination by copper and zinc. Research object were germinants of oat in amount of300 plants in each variant of the experiment. For the performance of the experiment, the sand was equally contaminated by sulfates of Cu and Zn in concentration of 2 MPC on its gross content in soil. The experiment lastedfor 2 weeks. For the implementation of the objective of research there was analyzed the contentof both Cu and Zn in plants exposed to soil contamination. Additionally there was performed an analysis of as the content of lipids peroxidation products, phenols and flavonoids; as well the activity ofperoxidase, catalase and photosynthetic system. Under the soil contamination by copper and zinc corresponding to 2 MPC the accumulation of heavy metals was established to be happening in plants. If compared copper accumulation was higher than zinc accumulation that can be explained by the high migration capability of zinc. Under combined impact of two metals there was revealed their antagonistic interaction. There was established an elevated content of lipids peroxidation products in cells as a sequence of the accumulation of heavy metals in plants. As a result of the elevation of the content of lipids peroxidation products there was revealed a raised activity ofphotosynthetic apparatus and antioxidant system (carotenoids, catalase and peroxidase) in the cell. The decrease of the content ofphenols and flavonoids is related with the usage of this system of antioxidant protection for the neutralization of lipids peroxidation processes. PMID- 29446591 TI - [Impact of waste landfills in the Saratov region on the sanitary condition of the soil]. AB - Monitoring of environment in regions of the location of waste landfills includes the implementation of the control over a sanitary condition of soils. The main origins of the spread ofpollutants into soils are the solid particles from aerosol emissions from the functioning of landfills transmitted to surrounding territories. Within zones of the impact of three largest waste landfills in the Saratov region (Aleksandrovsky, Guselsky in the city of Saratov and Balakovsky in the city of Balakovo) there were taken 152 soil samples. According to results of the estimation in soil concentration of gross and motile forms of heavy metals of the first (Zn, Cd, Ni) and the second danger classes (Cu, Cr, Pb) there was performed the analysis of coefficients of danger- K0 and total coefficients ofpollution - Zc. There was executed the assessment of both a sanitary and hygienic condition of soils and degree of danger ofpollution. The most contrast areal features of the distribution of the danger coefficient - Ko in soils are characteristic for motile forms of heavy metals. For all three studied objects persistently there is stood out the dangerous and areal pollution of soils by association of Ni and Cu . The danger ofpollution of soils by gross forms of heavy metals is minimum. The coefficient of total pollution of Zc exceeds admissible level on motile forms of heavy metals only for the soils surrounding the Balakovo landfill. In zones of the impact of waste landfills there are located the processed lands with an adverse sanitary and hygienic condition of soils. In the region of the Guselsky object soils of the processed agricultural grounds are dangerously polluted by motile forms of Ni and Cu. In vicinities of the Balakovo waste landfill considerable areas of private gardening enterprises are dangerously polluted by the motile forms of Ni, Cu and Zn.

AB - The mechanisms underlying the locomotion recovery in poststroke patients remain unknown. Navigated transcranial magnetic stimulation (nTMS) is a new method to evaluate the functional state of the motor system. Using of the exoskeleton complex (EC) allow to correct walking pattern significantly. The aim of this study was to evaluate the capability of nTMS to assess changes in gait cortical control using EC in poststroke patients. 14 patients suffered subcortical stroke, mean age was 53.0 years [49, 62], mean duration of a stroke of 14.2 [7.0; 23.0] months were included. All patients trained with EC for 10 times and also received standardized physical therapy. All patients underwent nTMS, as well as clinical assessment using a Fugl-Meyer Scale lower extremity section and 10 m walking test before and after trains. A significant decrease of time to walk 10 meter was observed, while Fugl-Meyer Score remained unchanged. Patients showed the significant reduction of the average latency of motor responses from the affected hemisphere and different patterns of size and localization changes in both legs' cortical motor areas. Navigates TMS may demonstrate individual patterns of changes in cortical representation of leg muscles in post-stroke patients with damage of various motor system elements, while using exoskeleton complex. Thus, navigated TMS may be used not only for verification of neuroplasticity process, but it may also provide its detailed description.

Among them are: the association of rooms according to a functional purpose; division of children collectives according to the age; rational placement of main rooms for the prevention ofpenetration of noise and pollution; ensuring convenientfunctional connections between different premises and group rooms and the parcel ofpreschool institutions; optimal solution of the light mode; rational air and thermal mode. There are made proposals for the expansion of the list of hygienic principles of the design of buildings of kindergartens: provision of conditions for realization of physical activity of children, the safe use of electronic educational equipment, and the creation of the barrier-free environment. There was established the insufficiency of areas of group rooms for the realization of voluntary motor activity of children in modern kindergartens and the need of the revision of the standard of the area of the group room per one child.

AB - The comparative research was carried to study basic indices of physical development and cardiovascular system in Aboriginals and north-born Europeans of different areas of Russia's northeast (Chukotsky Autonomous District, Magadan Region). According to most examined morphofunctional characteristics no significant differences were found between the groups of subjects that testify to the formation, under the current social conditions, of convergent adaptation processes typical for the two ethnic cohorts from the observed areas of residing. High percentage of asthenia in body constitution of young residents from Magadan Region was common and mostly demonstrated by Aboriginals of the Magadan city.

AB - In the article there are presented data on characteristics ofpeculiarities of the functional state of medical 1-6 years students of higher educational institutions. The results were obtained with the aid of variation pulsometry. Students were shown to have typical elevated tone of the sympathetic nervous system, especially for students of the 1, 3, 5 and 6 courses, that is confirmed by the amplitude mode (AMo), characterizing the sympathetic activity of autonomous nervous system (ANS), which is an average of the students 1 year accounted for 38.6 +/- 1.89%, for students of the 3 course - 38.5 +/- 1.72%, for students of the 5 year (40.9 +/- 3.25 %) and the students of 6 course (46.7 +/- 2.59%). There was determined the trend to the centralization of the heart rate control, as evidenced by a reduced proportion of high-frequency waves (HF) by 29.2% to 35.2%, exceeding by 3.6 to 14.4 times in waves of the very low frequency (VLF) relative to the average standard values; the high proportion of students from 41% to 52%, with a mismatch of the sympathetic and parasympathetic compartments of the autonomic nervous system in the regulation of biological processes of adaptation. For medical students of higher education institutions there are typical functional reserves reduced from 20.5 % to 97.6% and a decrease in the proportion of students with a satisfactory adaptation by 40.4% from the 1 to the 6th year.

AB - In the paper there are presented results of investigations of indices of the physical development of male adolescents aged of 11-17 years - residents of the 1 2 generation from new coming European migrants in the Magadan region during 2008 2014. There were observed 418 adolescents - representatives of the 1 generation, and 463 cases from the 2 generation. Representatives of the 2 generation in the initial period (11-12 years) were established to show higher tempos of growth. Maximal gains in the body length, body mass, and chest circumference in adolescents of the 1 generation occur at the age of 13-14 years, but in the 2 generation it is seen one year later - at the age of 14-15 years. In adolescents of each generation there was noted the high variability of the level of major indices of the physical development. However, among representatives of the 1 generation there is less proportion of cases with normal or average values of body length, body mass, and chest circumference along with larger proportion ofpersons with diverse deviations, as well deficit as excess in comparison with the 2 generation. At the final stage of the puberty age (17 years) more adolescents with microsomatic (25%) and disharmonic (38.2%) body constitution occur among the subjects from the 1 generation as compared to those of the 2 generation (19.7% and 28.2%, respectively).

AB - The article contains the review and analysis of data on the mechanisms of the toxic action of carbon nanotubes (CNTs) on the body and available results of CNT toxicological evaluation after inhalation and oral routes of the action. Identification of cellular and molecular mechanisms of CNTs toxicity allows to justify the list of the most sensitive biochemical toxicity markers that could be used for monitoring the occupational effects of CNTs and serve as a promising target for the corresponding pharmacological and immunopharmacological interventions aimed on specific prophylaxis and therapy of diseases caused by CNT. A considerable amount of experimental data obtained in vivo on inhalation animal models allows to establish the hygienic standardfor CNT in the air of the working area. As to safe levels of the oral route of CNT it needs further study for their reliable assessment. The search and selection of sources for the review was executed with the use of public databases, including (in order of relevance) PubMed, Scopus, Google Scholar, and RISC, for the period from 2004 to 2017.

AB - Multisegmental muscle responses (MMR) are reflexes in the leg muscles evoked by transcutaneous electrical spinal cord stimulation over the Th11-Th12 vertebrae. We have used MMR to evaluate the excitability of lumbosacral motor neurons in individuals suffering lower paraplegia. Ten individuals were tested using H reflexes and MMR bilaterally before (n 0 = 20) and during 4-weeks course of rehabilitation (n=76). The H-reflex and MMR of m. gastrocnemius lateralis were obtained in: 15 and 13 cases out of 20, respectively. Both reflexes were recorded in 11 and were absent in 3 cases, matched up to 70% of recordings. In dynamic, the both methods were 100% reproducible and the responses' amplitude varied in similar directions in 67% of records. The data confirm the validity and reproducibility of the MMR for evaluation of the motor neurons excitability in lumbosacral cord. The H-reflex magnitude shows moderate correlation with MMR in m. gastrocnemius lateralis (r = 0.59, p < 0.001), and low correlation with MMR in mm. rectus femoris, biceps femoris, and tibialis anterior (r < 0.40, p < 0.001). These findings do not allow extrapolate the results from the H-reflex measurement on the state of lumbosacral cord. At the same time, measurements of the MMR allow estimate simultaneously the excitability of motor pools innervating several muscle groups. This makes advantageous to assess the functional state of the motor neurons in the lumbosacral spinal cord for clinical and experimental studies, including the spinal cord damage. PMID- 29446610 TI - Self-Supported Stainless Steel Nanocone Array Coated with a Layer of Ni-Fe Oxides/(Oxy)hydroxides as a Highly Active and Robust Electrode for Water Oxidation. AB - Highly efficient, robust, and cheap water oxidation electrodes are of great significance for large-scale production of hydrogen by electrolysis of water. Here, a self-supported stainless steel (SS) nanocone array coated with a layer of nanoparticulate Ni-Fe oxides/(oxy)hydroxides was fabricated by a facile, low cost, and easily scalable two-step process. The construction of a nanocone array on the surface of an AISI 304 SS plate by acid corrosion greatly enlarged the specific surface area of the substrate, and the subsequent formation of a layer of Ni-Fe oxides/(oxy)hydroxides featuring the NiFe2O4 spinel phase on the nanocone surface by electrodeposition of [Ni(bpy)3]2+ significantly enhanced the intrinsic activity and the stability of the SS-based electrode. The as-prepared electrode demonstrated superior activity for the oxygen evolution reaction (OER) in 1 M KOH, with 232 and 280 mV overpotentials to achieve 10 and 100 mA cmgeo-2 current densities, respectively. The high activity of the electrode was maintained over 340 h of chronopotentiometric test at 20 mA cmgeo-2, and the electrode also showed good stability over 100 h of electrolysis at high current density (200 mA cm-2). More important for practical application, the used SS based electrode can be easily regenerated with the original OER activity. The superior activity of this SS-based electrode stems from synergistic combination of high conductivity of the SS substrate, a large electrochemically active surface area of the nanocone array, and a uniformly coated nanoparticulate Ni-Fe oxide/(oxy)hydroxide layer with an optimal Ni/Fe ratio. PMID- 29446611 TI - Lithium-Ion Batteries: Charged by Triboelectric Nanogenerators with Pulsed Output Based on the Enhanced Cycling Stability. AB - The triboelectric nanogenerator (TENG) has been used to store its generated energy into lithium-ion batteries (LIBs); however, the influences of its pulse current and high voltage on LIB polarization and dynamic behaviors have not been investigated yet. In this paper, it is found that LIBs based on the phase transition reaction of the lithium storage mechanism [LiFePO4 (LFP) and Li4Ti5O12 (LTO) electrodes] are more suitable for charging by TENGs. Thus, the enhanced cycling capacity, Coulombic efficiency (nearly 100% for LTO electrode), and energy storage efficiency (85.3% for the LFP-LTO electrode) are successfully achieved. Moreover, the pulse current has a positive effect on the increase of the Li-ion extraction, reducing the charge-transfer resistance ( Rct) for all studied electrodes as well (LFP, LiNi0.6Co0.2Mn0.2O2, LTO, and graphite). The excellent cyclability, high Coulombic, and energy storage efficiencies demonstrated the availability of storing pulsed energy generated by TENGs. This research has provided a promising analysis to obtain an enhanced charging methodology, which provides significant guidance for the scientific research of the LIBs. PMID- 29446612 TI - Total Capture, Convection-Limited Nanofluidic Immunoassays Exhibiting Nanoconfinement Effects. AB - Understanding nanoconfinement phenomena is necessary to develop nanofluidic technology platforms. One example of nanoconfinement phenomena is shifts in reaction equilibria toward reaction products in nanoconfined systems, which have been predicted theoretically and observed experimentally in DNA hybridization. Here we demonstrate a convection-limited nanofluidic immunoassay that achieves total capture of a target analyte and an apparent shift in the antibody-antigen reaction equilibrium due to nanoconfinement. The system exhibits wavefronts of the target analyte that propagate along the length of the nanochannel at a velocity much slower than that of the carrier fluid. We apply an analytical model describing the propagation of these wavefronts to determine the density of capture antibody binding sites in the enclosed nanochannel for a known concentration of the target analyte. We then use this binding site density to estimate the concentration of solutions with 5* and 10* less analyte. Our analysis suggests that nanoconfinement results in a preference toward binding of the target analyte with the surface-grafted capture antibody, as evidenced by an apparent reduction in the equilibrium dissociation constant. Our findings motivate the advancement of new biomedical and chemical synthesis technologies by leveraging nanoconfinement effects, and demonstrate a useful platform for studying the effect of nanoconfinement on chemical systems. PMID- 29446613 TI - Hierarchical FeNiP@Ultrathin Carbon Nanoflakes as Alkaline Oxygen Evolution and Acidic Hydrogen Evolution Catalyst for Efficient Water Electrolysis and Organic Decomposition. AB - Efficiency of hydrogen evolution via water electrolysis is mainly impeded by the kinetically sluggish oxygen evolution reaction (OER). Thus, it is of great significance to develop highly active and stable OER catalyst for alkaline water electrolysis or to substitute the more kinetically demanding acidic OER with a facile electron-donating reaction such that OER is no longer the bottleneck half reaction for either acidic or alkaline water electrolysis. Herein, the hierarchical Fe-Ni phosphide shelled with ultrathin carbon networks on Ni foam (FeNiP@C) is reported and shows exceptional OER activity and enhanced chemical stability in 1 M KOH. This unique electrode provides large active sites, facile electron transport pathways, and rapid gas release, resulting in a remarkable OER activity that delivers a current density of 100 mA/cm2 at an overpotential of 182 mV with a Tafel slope of 56 mV/dec. Combining the hydrogen evolution reaction with organic pollutant (methylene blue) oxidation, a multifunctional electrolyzer for simultaneous cost-effective hydrogen generation and organic pollutant decomposition in acid wastewater is proposed. Our strategies in this work provide attractive opportunities in energy- and environment-related fields. PMID- 29446614 TI - Interpenetrated and Polythreaded CoII-Organic Frameworks as a Supercapacitor Electrode Material with Ultrahigh Capacity and Excellent Energy Delivery Efficiency. AB - Synthesizing kinetically stable coordination polymers (CPs) through ligand functionalization can effectively improve their supercapacitive performances. Herein, we have successfully synthesized three novel and topological Co-CPs by varying the flexible N-donor ligand and inorganic anions, namely, interpenetrated [Co(HTATB)( o-bib)].H2O, extended two-dimensional (2D) layered Co(HTATB)( m bib).2H2O, and three-dimensional (3D) Co(HTATB)( m-bib), where bib is the flexible N-donor bis((1 H-imidazol-1-yl)methyl)benzene linker (where o- and m- refer to ortho and meta positions, respectively) ligand and HTATB is the partial deprotonation mode from 4,4',4"- s-triazine-2,4,6-triyl-tribenzoic acid. Various Co-CPs have been directly applied in the field of supercapacitors. All these framework materials exhibit high capacitance, excellent energy delivery efficiency, and good cycling performance. For instance, the maximum specific capacitance for penetrated 3D networks is 2572 F g-1 at 2.0 A g-1, and the mean energy delivery efficiency is up to 92.7% based on the tested current densities. Compared with extensional 2D layered and 3D networks, the 3D interpenetrated and polythreaded architectures could provide more active sites and thus promote fast charging and discharging processes. Furthermore, the Li+ uptake-release abilities of the Co-based CPs are also investigated, and the initial discharge capacity value for the 3D interpenetrated structures can reach up to 1792 mA h g-1 at a current density of 50 mA g-1. PMID- 29446615 TI - Leveraging Engineering of Cells for Drug Delivery. AB - Cell therapy has become a momentum-gathering treatment strategy for a variety of diseases, including cancer, diabetes, hemophilia, and cardiomyopathy. However, clinical applications of conventional cell therapies have often been compromised by rapid decline in viability and function of the transplanted cells due to host recognition and subsequent foreign body rejection. Along this line, cell engineering technologies such as cell encapsulation within microcapsules and immobilization in porous scaffolds have been implemented to address the immunosuppression concerns. As a recent emerging research topic, drawing inspiration from the ways that natural cells interact with the body has opened new avenues for cell engineering, such as direct modification of whole cells with synthetic materials and "top-down" integration of biological membranes with micro/nanomaterials, which aim to alleviate immune response while harnessing the complex biological functions of cells. In this Account, we summarize our recent contribution to the field of cell engineering methodologies, with which we have demonstrated their promising applications for cancer immunotherapy, targeted drug delivery, and blood glucose regulation. For example, inspired by the inherent ability of platelets to accumulate at wound sites and interact with circulating tumor cells, we exploited a targeted checkpoint antibody delivery strategy for treatment of postsurgical cancer recurrence and metastatic spread by covalent binding of platelets' cell surfaces with a monoclonal antibody against programmed death ligand 1 (aPDL1). Without interfering with the platelets' surgical-site homing property, the conjugated aPDL1 could be triggered to release in the form of microparticles after in situ activation. As an extension, we then engineered the platelet membrane to cloak nanoparticles for anticancer drug delivery, mimicking the targeting capability of the source cells while possessing prolonged circulation lifetime and insignificant immunogenicity. At the same time, we also found that the subcellular compartment membrane-derived particulates exhibited high specificity toward homotypic cells, by which enhanced intracellular drug delivery was achieved. Moreover, by taking advantage of the reversible interaction between glucose-derivative-modified insulin and the red blood cell membrane, we constructed a glucose-responsive smart insulin delivery system for long-term maintenance of blood glucose levels within a normal range. Recently, by virtue of painless microneedle patches as convenient cell engineering platforms, a minimally invasive intradermal antitumor vaccine was invented by integrating whole-tumor lysis into near-infrared light-illuminated microneedle patches. The microneedle patches also showed promise in combining with conventional cell encapsulation techniques, by which an externally positioned beta-cell engineering strategy was proposed for diabetes treatment. The results presented in this Account demonstrate distinct approaches to the development and application of cell engineering strategies for drug delivery.

AB - Although peptides, antibodies/antibody fragments, siRNAs, antisense DNAs, enzymes, and aptamers are all under development as possible therapeutic agents, the breadth of their applications has been severely compromised by their inability to reach intracellular targets. Thus, while macromolecules can often enter cells by receptor-mediated endocytosis, their missions frequently fail due to an inability to escape their entrapping endosomes. In this paper, we describe a general method for promoting release of any biologic material from any entrapping endosome. The strategy relies on the fact that all nascent endosomes contain extracellular (Na+-enriched) medium, but are surrounded by intracellular (K+-enriched) fluid in the cytoplasm. Osmotic swelling and rupture of endosomes will therefore be facilitated if the flow of K+ down its concentration gradient from the cytosol into the endosome can be facilitated without allowing downhill flow of Na+ from the endosome into the cytosol. While any K+ selective ionophore can promote the K+ specific influx, the ideal K+ ionophore will also exchange influxed K+ for an osmotically inactive proton (H+) in order to prevent buildup of an electrical potential that would rapidly halt K+ influx. The only ionophore that catalyzes this exchange of K+ for H+ efficiently is nigericin. We demonstrate here that ligand-targeted delivery of nigericin into endosomes that contain an otherwise impermeable fluorescent dye can augment release of the dye into the cell cytosol via swelling/bursting of the entrapping endosomes. We further show that nigericin-facilitated escape of a folate-targeted luciferase siRNA conjugate from its entrapping endosomes promotes rapid suppression of the intended luciferase reporter gene. Taken together, we propose that ionophore catalyzed entry of K+ into endosomal compartments can promote the release of otherwise impermeable contents from their encapsulating endosomes.

PMID- 29446620 TI - Polydopamine-Coated Main-Chain Liquid Crystal Elastomer as Optically Driven Artificial Muscle. AB - Optically driven active materials have received much attention because their deformation and motion can be controlled remotely, instantly, and precisely in a contactless way. In this study, we investigated an optically actuated elastomer with rapid response: polydopamine (PDA)-coated liquid crystal elastomer (LCE). Because of the photothermal effect of PDA coating and thermal responsiveness of LCE, the elastomer film contracted significantly with near-infrared (NIR) irradiation. With a fixed strain, light-induced actuating stress in the film could be as large as 1.5 MPa, significantly higher than the maximum stress generated by most mammalian skeletal muscle (0.35 MPa). The PDA-coated LCE films could also bend or roll up by surface scanning of an NIR laser. The response time of the film to light exposure could be as short as 1/10 of a second, comparable to or even faster than that of mammalian skeletal muscle. Using the PDA-coated LCE film, we designed and fabricated a prototype of robotic swimmer that was able to swim near the water-air interface by performing "swimming strokes" through reversible bending and unbending motions induced and controlled by an NIR laser. The results presented in this study clearly demonstrated that PDA-coated LCE is a promising optically driven artificial muscle, which may have great potential for applications of soft robotics and optomechanical coupling devices. PMID- 29446621 TI - Oxidative Dehydrogenation on Nanocarbon: Insights into the Reaction Mechanism and Kinetics via in Situ Experimental Methods. AB - Sustainable and environmentally benign catalytic processes are vital for the future to supply the world population with clean energy and industrial products. The replacement of conventional metal or metal oxide catalysts with earth abundant and renewable nonmetallic materials has attracted considerable research interests in the field of catalysis and material science. The stable and efficient catalytic performance of nanocarbon materials was discovered at the end of last century, and these materials are considered as potential alternatives for conventional metal-based catalysts. With its rapid development in the past 20 years, the research field of carbon catalysis has been experiencing a smooth transition from the discovery of novel nanocarbon materials or related new reaction systems to the atomistic-level mechanistic understanding on the catalytic process and the subsequent rational design of the practical catalytic reaction systems. In this Account, we summarize the recent progress in the kinetic and mechanistic studies on nanocarbon catalyzed alkane oxidative dehydrogenation (ODH) reactions. The paper attempts to extract general concepts and basic regularities for carbon catalytic process directing us on the way for rational design of novel efficient metal-free catalysts. The nature of the active sites for ODH reactions has been revealed through microcalorimetric analysis, ambient pressure X-ray photoelectron spectroscopy (XPS) measurement, and in situ chemical titration strategies. The detailed kinetic analysis and in situ catalyst structure characterization suggests that carbon catalyzed ODH reactions involve the redox cycles of the ketonic carbonyl-hydroxyl pairs, and the key physicochemical parameters (activation energy, reaction order, and rate/equilibrium constants, etc.) of the carbon catalytic systems are proposed and compared with conventional transition metal oxide catalysts. The proposal of the intrinsic catalytic activity (TOF) provides the possibility for the fair comparisons of different nanocarbon catalysts and the consequent structure function relation regularity. Surface modification and heteroatom doping are proved as the most effective strategies to adjust the catalytic property (activity and product selectivity etc.) of the nanocarbon catalysts. Nanocarbon is actually a proper candidate platform helping us to understand the classical catalytic reaction mechanism better, since there is no lattice oxygen and all the catalytic process happens on nanocarbon surface. This Account also exhibits the importance of the in situ structural characterizations for heterogeneous nanocarbon catalysis. The research strategy and methods proposed for carbon catalysts may also shed light on other complicated catalytic systems or fields concerning the applications of nonmetallic materials, such as energy storage and environment protection etc. PMID- 29446622 TI - Hyper-Cross-linked Porous MoS2-Cyclodextrin-Polymer Frameworks: Durable Removal of Aromatic Phenolic Micropollutant from Water. AB - A reasonable and efficient strategy for the construction of hyper-cross-linked porous MoS2-CD-polymer frameworks (MoS2CDPFs) was demonstrated. Here, MoS2 nanosheets (NSs) can be decorated with amino functionalized beta-cyclodextrin, producing a nanoscale structural motif (MoS2@CD) for the synthesis of MoS2CDPFs. We demonstrated that CD polymer (CDP) as linker can be uniformly incorporated into the frameworks. Except for the pores created between MoS2 NSs, polymer doping generates extra interspace between MoS2 NSs and CD monomer. Interestingly, the resultant MoS2CDPFs can rapidly sequester aromatic phenolic micropollutant bisphenol A (0.1 mM) from water with 93.2% adsorption capacity, which is higher than that of MoS2, MoS2@CD, and CDP. The intercalation between MoS2 sheets with CDP imparts the frameworks durability in adsorption/desorption of aromatic phenolic micropollutants. Remarkably, the removal efficiency reduced only 3% after 10 regeneration-reuse cycles. These findings demonstrated that the porous MoS2-CD-polymer-based frameworks are promising adsorbents for rapid, flow-through water remediation.

AB - Using coumarin-modified diphenylalanine (CO-FF) and gamma-cyclodextrin (gamma-CD) as building blocks, we successfully constructed one-dimensional nanofibers with several nanometers in width and tens of micrometers in length. Through the photodimerization of coumarin units in CO-FF?gamma-CD complexes, the resultant nanofibers could be cross-linked to organic 2D thin films with a lateral dimension of tens of micrometers and a thickness of nanometers. The resultant thin films exhibited a significant fluorescence enhancement for twisted intramolecular charge-transfer (TICT) molecules and effective removal of pollutant from water through filtration. This 1D -> 2D morphological conversion controlled by light may provide a novel strategy to construct the highly ordered nanostructures that can be used as templates for making nanoscaled materials with defined sizes and shapes. PMID- 29446624 TI - Hydrogen-Assisted Growth of Large-Area Continuous Films of MoS2 on Monolayer Graphene. AB - We show how control over the chemical vapor deposition (CVD) reaction chemistry of molybdenum disulfide (MoS2) by hydrogen addition can enable the direct growth of centimeter-scale continuous films of vertically stacked MoS2 monolayer on graphene under atmospheric pressure conditions. Hydrogen addition enables longer CVD growth times at high temperature by reducing oxidation effects that would otherwise degrade the monolayer graphene. By careful control of nucleation density and growth time, high-quality monolayer MoS2 films could be formed on graphene, realizing all CVD-grown vertically stacked monolayer semimetal/semiconducting interfaces. Photoluminescence spectroscopy shows quenching of MoS2 by the underlying graphene, indicating a good interfacial charge transfer. We utilize the MoS2/graphene vertical stacks as photodetectors, with photoresponsivities reaching 2.4 A/W under 135 MUW 532 nm illumination. This approach provides insights into the scalable manufacturing of high-quality two dimensional electronic and optoelectronic devices.

AB - A combination of carbon dioxide (CO2) capture and chemical fixation in a one-step process is attractive for chemists and environmentalists. In this work, by incorporating chelating multiamine sites to enhance the binding affinity toward CO2, two novel metal-organic frameworks (MOFs) [Zn2(L)(2,6 NDC)2(H2O)].1.5DMF.2H2O (1) and [Cd2(L)(2,6-NDC)2].1.5DMF.2H2O (2) (L = N1-(4-(1 H-1,2,4-triazole-1-yl)benzyl)- N1-(2-aminoethyl)ethane-1,2-diamine, 2,6-H2NDC = 2,6-naphthalenedicarboxylic acid, DMF = N, N-dimethylformamide) were achieved under solvothermal conditions. Both 1 and 2 possess high selectivity for adsorption of CO2 over CH4 at room temperature under atmospheric pressure. Moreover, 1 has one-dimensional tubular channels decorated with multiactive sites including NH2 groups and coordination unsaturated Lewis acid metal sites, leading to efficient catalytic activity for chemical fixation of CO2 by reaction with epoxides to give cyclic carbonates under mild conditions.

AB - Lipid droplets (LDs) are intracellular lipid-rich organelles that regulate the storage of neutral lipids and were recently found to be involved in many physiological processes, metabolic disorders, and diseases including obesity, diabetes, and cancers. Herein we present a family of new fluorogenic merocyanine fluorophores based on an indolenine moiety and a dioxaborine barbiturate derivative. These so-called StatoMerocyanines (SMCy) fluoresce from yellow to the near-infrared (NIR) in oil with an impressive fluorescence enhancement compared to aqueous media. Additionally, SMCy display remarkably high molar extinction coefficients (up to 390 000 M-1 cm-1) and high quantum yield values (up to 100%). All the members of this new family specifically stain the LDs in live cells with very low background noise. Unlike Nile Red, a well-known lipid droplet marker, SMCy dyes possess narrow absorption and emission bands in the visible, thus allowing multicolor imaging. SMCy proved to be compatible with fixation and led to high-quality 3D images of lipid droplets in cells and tissues. Their high brightness allowed efficient tissue imaging of adipocytes and circulating LDs. Moreover their remarkably high two-photon absorption cross-section, especially SMCy5.5 (up to 13 300 GM), as well as their capacity to efficiently fluoresce in the NIR region led to two-photon multicolor tissue imaging (liver). Taking advantage of the available color palette, lipid droplet exchange between cells was tracked and imaged, thus demonstrating intercellular communication.

AB - Planarity of the amide bond represents one of the most widely recognized properties of amides. Herein, we report a combined structural and computational study on the effect of ortho-substitution on resonance and barriers to rotation in tertiary aromatic amides. We demonstrate that ortho-chloro substitution in a class of benzamides that are important from the reactivity and medicinal chemistry perspective results in increased barriers to rotation around both the N C(O) and C-C(O) axes. The effect of steric hindrance on structures, resonance energies, barriers to rotation, and proton affinities is discussed. The present study strongly supports the use of ortho-substitution in common benzamides to strengthen amidic resonance. PMID- 29446629 TI - Microplastics in Swiss Floodplain Soils. AB - Microplastics (MPs) are small (<5 mm diameter) but have clear implications for the environment. These artificial particles are found in and pose threats to aquatic systems worldwide. MPs have terrestrial sources, but their concentrations and fates in the terrestrial environment are poorly understood. While global plastic production continues to increase, so do the environmental concentrations and impacts of MPs. In this first study of MPs in floodplain soils, we developed a method for identifying, quantifying, and measuring the sizes of most commonly produced MPs in soil by FT-IR microscopy. For small MP (<1 mm) analysis, MP were separated by density separation and oxidation of organic matter. In this study we analyzed 29 floodplains in Swiss nature reserves associated with catchments covering 53% of Switzerland. We found evidence that 90% of Swiss floodplain soils contain MPs. The highest MP concentrations were associated with the concentration of mesoplastics (5 mm - 2.5 cm diameter), indicating plastic waste as source. Furthermore, MP concentration was correlated with the population of the catchment. The wide distribution of MPs, their presence in remote unsettled high mountain areas, decoupling of MEP and MP compositions, and the dominance of MPs by small (<500 MUm diameter) particles, indicate that MPs enter soils via diffuse aeolian transport.

This finding confirms experimental results for lanthanum and gadolinium showing the highest remanent polarization values of all hafnia-based ferroelectric films until now. However, no comprehensive overview that links structural properties to the electrical performance of the films in detail is available for lanthanide-doped hafnia. La:HfO2 appears to be a material with a broad window of process parameters, and accordingly, by optimization of the La content in the layer, it is possible to improve the performance of the material significantly. Variations of the La concentration leads to changes in the crystallographic structure in the bulk of the films and at the interfaces to the electrode materials, which impacts the spontaneous polarization, internal bias fields, and with this the field cycling behavior of the capacitor structure. Characterization results are compared to other dopants like Si, Al, and Gd to validate the advantages of the material in applications such as semiconductor memory devices.

AB - This is a comprehensive study on mobilization/speciation and temporal/spatial variation of atmospheric arsenic (As) deposition in the Pearl River Delta (PRD) region. A set of experimental procedures was established for measuring the deposition fluxes of individual As species. The deposition carrying inorganic AsIII % was significantly higher than that contained in atmospheric particles. Compared with dry deposition, wet deposition was much more harmful to the regional ecosystem, as it contributed the majority of bulk deposition (>75%) and carried most of the mobilized iAsIII compounds. A stepwise linear regression model was utilized to identify the factors influencing total As deposition (wet: precipitation and PM2.5, dry: relative humidity, wind speed, and PM10, bulk: precipitation, PM2.5, and wind speed). By examining the representativeness of the study sites and comparison with the literature data, the statistic models were verified to explain the temporal/spatial variation of total As deposition in the entire PRD region, where significant seasonal variation was only found for wet deposition (wet season > dry season). The annual As load contributed from regional atmospheric deposition increased from 2013 to 2015, when the contributions of individual cities varied annually. PMID- 29446631 TI - Mechanistic Investigation and Multiplexing of Liposome-Assisted Metabolic Glycan Labeling. AB - Metabolic labeling of glycans with bioorthogonal reporters has been widely used for glycan imaging and glycoproteomic profiling. One of the intrinsic limitations of metabolic glycan labeling is the lack of cell-type selectivity. The recently developed liposome-assisted bioorthogonal reporter (LABOR) strategy provides a promising means to overcome this limitation, but the mechanism of LABOR has not been investigated in detail. In this work, we performed a mechanistic study on LABOR and explored its multiplexing capability. Our studies support an endocytosis-salvage mechanism. The ligand-targeted liposomes encapsulating azidosugars are internalized into the endosome via the receptor-mediated endocytosis. Unlike the conventional drug delivery, LABOR does not rely on the endosomal escape pathways. Rather, the liposomes are allowed to enter the lysosome, inside which the azidosugars are released from the liposomes. The released azidosugars then intercept the salvage pathways of monosaccharides and get transported into the cytosol by lysosomal sugar transporters. Based on this mechanism, we expanded the scope of LABOR by evaluating a series of ligand receptor pairs for targeting sialoglycans in various cell types. Different ligand types including small molecules, antibodies, aptamers, and peptides could be easily implemented into LABOR. Finally, we demonstrated that the sialoglycans in two distinct cell populations in a co-cultured system could be selectively labeled with two distinct chemical reporters by performing a multiplexed LABOR labeling. PMID- 29446633 TI - Molecular Dynamics Study of the Solution Structure, Clustering, and Diffusion of Four Aqueous Alkanolamines. AB - CO2 sequestration from anthropogenic resources is a challenge to the design of environmental processes at a large scale. Reversible chemical absorption by amine based solvents is one of the most efficient methods of CO2 removal. Molecular simulation techniques are very useful tools to investigate CO2 binding by aqueous alkanolamine molecules for further technological application. In the present work, we have performed detailed atomistic molecular dynamics simulations of aqueous solutions of three prototype amines: monoethanolamine (MEA) as a standard, 3-aminopropanol (MPA), 2-methylaminoethanol (MMEA), and 4-diethylamino 2-butanol (DEAB) as potential novel CO2 absorptive solvents. Solvent densities, radial distribution functions, cluster size distributions, hydrogen-bonding statistics, and diffusion coefficients for a full range of mixture compositions have been obtained. The solvent densities and diffusion coefficients from simulations are in good agreement with those in the experiment. In aqueous solution, MEA, MPA, and MMEA molecules prefer to be fully solvated by water molecules, whereas DEAB molecules tend to self-aggregate. In a range from 30/70 50/50 (w/w) alkanolamine/water mixtures, they form a bicontinuous phase (both alkanolamine and water are organized in two mutually percolating clusters). Among the studied aqueous alkanolamine solutions, the diffusion coefficients decrease in the following order MEA > MPA = MMEA > DEAB. With an increase of water content, the diffusion coefficients increase for all studied alkanolamines. The presented results are a first step for process-scale simulation and provide important qualitative and quantitative information for the design and engineering of efficient new CO2 removal processes.

AB - An unusual strategy toward novel substituted benzo[b]thiophenes has been developed. The generation of arynes in the presence of acyl ketene dithioacetals resulted in a cascade reaction involving [3 + 2] cycloaddition, and a dealkylative arylation of a thioether moiety to afford 2,3-disubstuted benzo[b]thiophenes. This route represents an expeditious approach to benzothiophenes that employs acyl ketene dithioacetals as dipoles. PMID- 29446636 TI - Mapping the Extra Solvent Power of Ionic Liquids for Monomers, Polymers, and Dry/Wet Globular Single-Chain Polymer Nanoparticles. AB - Ionic liquids (ILs) have shown advantages in organic synthesis and catalysis, energy storage and conversion, and a variety of pharmaceutical applications. Understanding the miscibility behavior of IL/monomer, IL/polymer, and IL/polymer nanoparticle mixtures is critical for the use of ILs as green solvents in polymerization processes as well as to rationalize recent observations concerning the superior solubility of some proteins in ILs when compared to standard solvents. In this work, the most relevant results obtained in terms of extended three-component Flory-Huggins theory concerning the extra solvent power (ESP) of ILs when compared to traditional nonionic solvents for monomeric solutes (Case I), linear polymers (Case II), dry (i.e., without IL inside) globular single chain polymer nanoparticles (SCNPs) (Case III), and wet (i.e., with IL inside) globular SCNPs (Case IV) are presented. Moreover, useful ESP maps are drawn for the first time for IL mixtures corresponding to Cases I, II, III, and IV at a constant temperature and pressure. Finally, a potential pathway to improve the miscibility of nonionic polymers in ILs is proposed.

The corresponding adducts were obtained in good yields (85%-96%) with excellent enantioselectivities (up to >99%). This protocol exhibits extraordinary reactivity, because of the fact that a complex with as little as 0.05 mol % Rh(III) can catalyze the title reaction on a gram-scale with excellent enantioselectivity. PMID- 29446639 TI - Two-Dimensional Electronic Spectroscopy Reveals Dynamics and Mechanisms of Solvent-Driven Inertial Relaxation in Polar BODIPY Dyes. AB - In this work, we demonstrate the use of two-dimensional electronic spectroscopy (2DES) to study the mechanism and time scale of the femtosecond Stokes shift dynamics in molecules characterized by intramolecular charge transfer, such as distyryl-functionalized boron dipyrromethene (BODIPY) molecules. The obtained results demonstrate that 2DES allows clear and direct visualization of the phenomenon. The analysis of the 2D data in terms of 2D frequency-frequency decay associated maps provides indeed not only the time scale of the relaxation process but also the starting and the final point of the energy flow and the associated reorganization energy, identified by looking at the coordinates of a negative signature below the diagonal. The sensitivity of the 2DES technique to vibrational coherence dynamics also allowed the identification of a possible relaxation mechanism involving specific interaction between a vibrational mode of the dye and the solvent.

PMID- 29446641 TI - Persistent mania following cessation of corticosteroids. AB - OBJECTIVES: The aims of this study are to describe two patients whose manic symptoms persisted for several months after the cessation of corticosteroids, to review the literature and to suggest treatment. METHODS: The presentation of two elderly patients with persistent manic symptoms following cessation of corticosteroids several months previously afforded the author the opportunity to examine them carefully, investigate and treat them. RESULTS: The patients were investigated to rule out other causes and were treated with sodium valproate and quetiapine (in the second patient). When well, the medications were slowly decreased and stopped. Both patients were well at one-year follow-up. CONCLUSIONS: Manic symptoms may persist for many months after stopping corticosteroids and active treatment is needed to control them.

AB - AIM: To understand the effects of gallic acid (GA) on ampicillin (Amp) sensitive or resistant strain of Pseudomonas sp. and also in modulating the corresponding biofilms. METHODOLOGY: The cell viability was determined by broth dilution, dry weight and CFU assays. Biofilm formation was measured by crystal violet assay while oxygen consumption rate was measured to verify the metabolic status of the cells. The membrane damage and drug efflux/accumulation were studied by fluorimetric assays. RESULTS: GA transformed the Amp resistant cells, both planktonic and biofilms, into highly sensitive one by inducing membrane damage and enhancing accumulation of drug, whereas the Amp sensitive cells gained resistance against Amp. CONCLUSION: Use of GA as an antimicrobial compound should be analyzed more critically depending on the drug dosages, drug sensitivity as well as types of bacterial strains being studied. PMID- 29446643 TI - Traditional consumption of and rearing edible insects in Africa, Asia and Europe. AB - The traditional consumption of edible insects is common in one third of the world's population, mostly in Latin America, Africa and Asia. There are over one thousand identified species of insects eaten in some stage of their life cycle; and they play important roles in ensuring food security. The most common way to collect insects are from the wild, which is seasonal with limited availability and has an increasing demand resulting in a disruption to the ecosystem. There is a growing interest shown in rearing insects for commercial purposes, and an industrial scale production will be required to ensure steady supplies. Industrial production will need to take into account the living environment of insects, the nutritional composition of their feed and the overall efficiency of the production system. We provide a short overview on the consumption of and rearing insects in Africa, Asia and Europe. For Africa, a snapshot is given for Nigeria, Ghana, Central African Republic, Kenya and Uganda, while the following countries are reported for Asia: China, Japan, Lao People's Democratic Republic, Thailand and Vietnam. In addition, a list of insect species with the highest potential for food and feed in the European Union is provided with some reference to The Netherlands and Finland. The review concludes that there is need to better understand the rearing and farming procedures that will yield high quality edible insects in Africa, Asia and Europe. PMID- 29446644 TI - An algorithm for managing adults who refuse medical treatment in New South Wales. AB - OBJECTIVES: The assessment and management of a patient who refuses medical treatment requires clinical skill, and consideration of the relevant law and the patient's decision-making capacity. Psychiatrists are often asked to advise in these situations. We aimed to develop an algorithm describing the relevant legal pathways to assist clinicians, especially psychiatrists, working in New South Wales (NSW), Australia. METHODS: We reviewed the academic literature on treatment refusal, relevant legislation, judicial rulings and NSW Health policy directives and guidelines. We consulted with clinicians and representatives of relevant tribunals. RESULTS: We developed an algorithm for managing patients who refuse medical treatment in NSW. The algorithm emphases the evaluation of decision making capacity and tracks separate pathways depending upon a person's status under the Mental Health Act 2007 (NSW). CONCLUSIONS: The algorithm provides a clear decision tree for clinicians responding to a patient refusing medical treatment in NSW. PMID- 29446646 TI - Accuracy of flash glucose monitoring and continuous glucose monitoring technologies: Implications for clinical practice. AB - Continuous glucose monitoring and flash glucose monitoring technologies measure glucose in the interstitial fluid and are increasingly used in diabetes care. Their accuracy, key to effective glycaemic management, is usually measured using the mean absolute relative difference of the interstitial fluid sensor compared to reference blood glucose readings. However, mean absolute relative difference is not standardised and has limitations. This review aims to provide a consensus opinion on assessing accuracy of interstitial fluid glucose sensing technologies. Mean absolute relative difference is influenced by glucose distribution and rate of change; hence, we express caution on the reliability of comparing mean absolute relative difference data from different study systems and conditions. We also review the pitfalls associated with mean absolute relative difference at different glucose levels and explore additional ways of assessing accuracy of interstitial fluid devices. Importantly, much data indicate that current practice of assessing accuracy of different systems based on individualised mean absolute relative difference results has limitations, which have potential clinical implications. Healthcare professionals must understand the factors that influence mean absolute relative difference as a metric for accuracy and look at additional assessments, such as consensus error grid analysis, when evaluating continuous glucose monitoring and flash glucose monitoring systems in diabetes care. This in turn will ensure that management decisions based on interstitial fluid sensor data are both effective and safe. PMID- 29446645 TI - The relationship of perivascular adipose tissue and atherosclerosis in the aorta and carotid arteries, determined by magnetic resonance imaging. AB - BACKGROUND AND AIMS: Imaging studies have relied on the 'overall' volumetric quantification of perivascular adipose tissue. We sought to assess the relationship of circumferential distribution between perivascular adipose tissue and adjacent wall thickness of carotid and aortic arteries using dedicated magnetic resonance imaging sequences. METHODS: Vessel wall and perivascular adipose tissue were acquired using magnetic resonance imaging (1.5 T). Co registered images were segmented separately, and measurements of both perivascular adipose tissue and vessel wall were obtained along radii of the vessel spaced at angles of 5 degrees each. RESULTS: In total, 29 patients were recruited. Perivascular adipose tissue thickness of the aorta was 3.34 +/- 0.79 mm with specific pattern of 'double peaks' distribution, while carotid perivascular adipose tissue had no identifiable pattern with thickness of 0.8 +/- 0.91 mm. Although statistically significant, the correlation between perivascular adipose tissue thickness and wall thickness in carotid arteries with normal (r = 0.040, p = 0.001) or with abnormal wall thickness (r = -0.039, p = 0.015) was merely nominal. Similarly, perivascular adipose tissue of the aorta had very weak correlation with normal aortic wall thickness (r = 0.010, p = 0.008) but not with the abnormal ones (r = -0.05, p = 0.29). CONCLUSION: Dissociation between the spatial distribution of perivascular adipose tissue and arterial wall thickening in the aorta and carotid arteries does not support that perivascular adipose tissue has a causal role in promoting atherosclerotic plaque via a paracrine route. Yet, perivascular adipose tissue functional properties were not examined in this study. PMID- 29446648 TI - Electromagnetic Field Could Protect SH-SY5Y Cells Against Cisplatin Cytotoxicity, But Not MCF-7 Cells. AB - Cisplatin [cis-dichlorodiammine platinum (II), CDDP], morphine (Mor), and electromagnetic field (EMF) induced oxidative stress. In this study, we tried to increase the cytotoxicity of CDDP in combination with Mor and/or EMF in MCF-7 and SH-SY5Y cells. Furthermore, we evaluate the expression levels of 11 antioxidant genes in both cell lines. We designed four treatments: CDDP alone, "CDDP+Mor," "CDDP+EMF," and "CDDP+Mor+EMF." Serial dilutions of CDDP, Mor (5.0 MUM), and EMF (50 Hz, 0.50 mT, "15 min field-on/15 min field-off") were used for estimation of relative IC50 values. The mRNA expression levels of antioxidant genes were determined by real-time PCR. The IC50 value of CDDP in "CDDP+Mor+EMF" treatment was significantly higher than CDDP alone and "CDDP+Mor" treatments in both cell lines. Whereas the expression levels of antioxidant genes in the four treatments showed similar patterns in MCF-7 cells, in SH-SY5Y cells, most of the antioxidant genes showed an upregulation with "CDDP+EMF" and "CDDP+Mor+EMF" treatments. Moreover, significant differences in the number of upregulated genes were observed between different treatments in SH-SY5Y cells. The molecular mechanism of CDDP-reduced cytotoxicity in our designed combinations is probably different in MCF-7 and SH-SY5Y cells. CDDP in combination with EMF could protect SH-SY5Y cells from the cytotoxicity, whereas it has no significant change in MCF-7 cells.

AB - Anaerobes represent the dominating population in the human gut microbiota and play a key role in gut homeostasis. In addition, several anaerobes are now considered as probiotics and they remain essential to several processes in the field of biotechnology. With the implementation of MALDI-TOF MS in routine laboratories, anaerobes are no longer neglected in clinical microbiology, as their identification is made easy. However, the isolation and identification of anaerobic bacteria, remains time consuming, fastidious and costly. Various strategies have been developed, from sampling to culturing human specimens, which will be discussed in this paper. Also, particular attention is paid to isolating species with special medical importance, as for contribution to the field of culturomics.

AB - : Blancher, Marc, Francois Albasini, Fidel Elsensohn, Ken Zafren, Natalie Holzl, Kyle McLaughlin, Albert R. Wheeler III, Steven Roy, Hermann Brugger, Mike Greene, and Peter Paal. Management of multi-casualty incidents in mountain rescue: Evidence-based guidelines of the International Commission for Mountain Emergency Medicine (ICAR MEDCOM). High Alt Med Biol. 19:131-140, 2018. INTRODUCTION: Multi Casualty Incidents (MCI) occur in mountain areas. Little is known about the incidence and character of such events, and the kind of rescue response. Therefore, the International Commission for Mountain Emergency Medicine (ICAR MEDCOM) set out to provide recommendations for the management of MCI in mountain areas. MATERIALS AND METHODS: Details of MCI occurring in mountain areas related to mountaineering activities and involving organized mountain rescue were collected. A literature search using (1) PubMed, (2) national mountain rescue registries, and (3) lay press articles on the internet was performed. The results were analyzed with respect to specific aspects of mountain rescue. RESULTS: We identified 198 MCIs that have occurred in mountain areas since 1956: 137 avalanches, 38 ski lift accidents, and 23 other events, including lightning injuries, landslides, volcanic eruptions, lost groups of people, and water related accidents. DISCUSSION: General knowledge on MCI management is required. Due to specific aspects of triage and management, the approach to MCIs may differ between those in mountain areas and those in urban settings. CONCLUSIONS: Mountain rescue teams should be prepared to manage MCIs. Knowledge should be reviewed and training performed regularly. Cooperation between terrestrial rescue services, avalanche safety authorities, and helicopter crews is critical to successful management of MCIs in mountain areas.

AB - OBJECTIVE: To evaluate olfactory function and clinical-neurological characteristics in a group of patients with mild head trauma. METHODS: A total of 352 patients with MTBI underwent olfactory function evaluation. The site of head trauma, loss of consciousness <20 min, memory loss, subjective presence or absence of olfaction and other clinical, neurological and radiological aspects were evaluated and compared with the olfactory dysfunction. RESULTS: A total of 33.5% patients enrolled in the study had an olfactory dysfunction. Eighty-seven percent of the patients had a diagnosis of anosmia whereas 13% had a diagnosis of hyposmia. Statistical analysis did not show a correlation between radiologically detected head lesions and different types of olfactory dysfunction (p > 0.05). Besides, no difference between head lesion site and different olfactory dysfunction was reported (p = 0.5). Regarding olfactory sub-tests a low detection threshold was present in these patients. CONCLUSION: The possibility of olfactory dysfunction should be considered in any case of MTBI appears differently than expected, a minor head injury causes anosmia much more frequently than hyposmia. PMID- 29446652 TI - Developmental regulation of the intestinal FGF19 system in domestic pigs. AB - Fibroblast growth factor-19 (FGF19) is an emerging endocrine factor involved in the regulation of bile acid homeostasis and energy metabolism in rodents and humans. In pigs, however, the FGF19 system remains largely unexplored. This study was designed to investigate the developmental regulation of the FGF19 system in domestic pigs. Samples of intestinal sections, liver, and plasma were collected from 24 pigs ( n = 6) at four developmental stages (birth, preweaning, postweaning, and adulthood). In the intestine, expression of the farnesoid X receptor (FXR) and FGF19 showed a congruent time- and region-dependent regulation, beginning soon after birth to achieve maximal expression in ileum during adulthood. The same temporal pattern was followed by the circulating concentration of FGF19, and these changes were accompanied by a time-related increase in the ileal proportion of bile acids that potently activate FXR. Conversely, genes belonging to the FGF19 signaling machinery achieved maximal expression in the small intestine at birth to decrease sharply afterward. In the liver, gene expression of FGF19 receptors and enzymes involved in bile acid biosynthesis paralleled after-birth changes in plasma concentration of this enterokine and attained a maximum during postweaning when plasma FGF19 was the lowest. Although detectable at birth, the hepatic expression of genes belonging to the bile acid-FXR-FGF19 pathway was low before the onset of enteral feeding. In summary, the porcine FGF19 system is present from birth, operative before the onset of enteral feeding, and regulated in a temporal and section-specific manner. NEW & NOTEWORTHY Fibroblast growth factor-19 (FGF19) is an emerging endocrine factor. The domestic pig is a translational model of value in biomedical research. We show for the first time that in pigs the intestinal FGF19 system is present from birth, operative before the onset of enteral feeding, and regulated in a temporal and section-specific manner. This work identifies pigs as a suitable model for investigating the implications of FGF19 signaling within and beyond the gut-liver axis. PMID- 29446654 TI - Hypouricaemic effects of yoghurt containing Lactobacillus gasseri PA-3 in patients with hyperuricaemia and/or gout: A randomised, double-blind, placebo controlled study. AB - PURPOSE: Lactobacillus gasseri PA-3 (PA-3) has been previously shown to decrease serum uric acid (SUA) levels in subjects with increased SUA. In this study, we investigated whether PA-3 is also capable of decreasing SUA levels in patients with hyperuricaemia and/or gout. METHODS: Twenty-five patients with hyperuricaemia and/or gout completed this study. Urate-lowering drugs were discontinued for 12 weeks (week -4 to week 8). After flushing of urate-lowering drugs for 4 weeks (week 0), patients were randomised equally to receive diets containing yoghurt beverages with PA-3 or without PA-3 for a duration of 8 weeks (week 8). The intention to treat (ITT) population included all subjects who were randomised, and the per-protocol (PP) population included subjects who completed the experiment with compliance. We evaluated SUA levels at the end of the study as well as changes in SUA levels in comparison to week 0. RESULTS: In both ITT and PP analyses, there were no significant differences in SUA levels or in the changes in SUA levels compared to week 0 between the two groups. However, in a sub-population whose SUA levels at week 0 were within one SD of the mean of the whole PP population, changes in SUA levels in the group consuming PA-3-containing yoghurt were significantly lower than those of the control group (p = .0378). CONCLUSION: PA-3-containing yoghurt improves SUA levels, even in patients with hyperuricaemia and/or gout. PMID- 29446653 TI - cGAS-mediated autophagy protects the liver from ischemia-reperfusion injury independently of STING. AB - Liver ischemia-reperfusion (I/R) injury occurs through induction of oxidative stress and release of damage-associated molecular patterns (DAMPs), including cytosolic DNA released from dysfunctional mitochondria or from the nucleus. Cyclic guanosine monophosphate-adenosine monophosphate (cGAMP) synthase (cGAS) is a cytosolic DNA sensor known to trigger stimulator of interferon genes (STING) and downstream type 1 interferon (IFN-I) pathways, which are pivotal innate immune system responses to pathogen. However, little is known about the role of cGAS/STING in liver I/R injury. We subjected C57BL/6 (WT), cGAS knockout (cGAS-/ ), and STING-deficient (STINGgt/gt) mice to warm liver I/R injury and that found cGAS-/- mice had significantly increased liver injury compared with WT or STINGgt/gt mice, suggesting a protective effect of cGAS independent of STING. Liver I/R upregulated cGAS in vivo and also in vitro in hepatocytes subjected to anoxia/reoxygenation (A/R). We confirmed a previously published finding that hepatocytes do not express STING under normoxic conditions or after A/R. Hepatocytes and liver from cGAS-/- mice had increased cell death and reduced induction of autophagy under hypoxic conditions as well as increased apoptosis. Protection could be restored in cGAS-/- hepatocytes by overexpression of cGAS or by pretreatment of mice with autophagy inducer rapamycin. Our findings indicate a novel protective role for cGAS in the regulation of autophagy during liver I/R injury that occurs independently of STING. NEW & NOTEWORTHY Our studies are the first to document the important role of cGAS in the acute setting of sterile injury induced by I/R. Specifically, we provide evidence that cGAS protects liver from I/R injury in a STING-independent manner. PMID- 29446655 TI - MicroRNAs as molecular targets of quercetin and its derivatives underlying their biological effects: A preclinical strategy. AB - Quercetin is a well-known flavonoid naturally occurring in most of the plant foods and is often found in the human diet. It can act as a potent antioxidant and anti-inflammatory agent, and plays significant roles in the prevention of various chronic diseases. Recent findings revealed that quercetin could affect metabolic traits by regulating certain transcription factors or key proteins involved in cellular signal pathways and influencing the expression of functional genes along with related regulatory pathway(s), and that microRNAs (miRNAs) circulate in body fluids and are involved in post-transcriptional gene silencing and regulation of gene expression in various biological processes including development, proliferation, metabolism and inflammation. This article reviews the studies into the molecular pathways underlying the beneficial bioactivities of quercetin and its derivatives, and the modulatory effects of miRNAs by quercetin and its derivatives on miRNAs-mediated cellular processes. MicroRNAs as molecular targets of quercetin and its derivatives and as predictive biomarkers for early diagnosis of the outcome of quercetin-rich diets are highlighted. Current limitations and future directions of research on the impact and associated mechanism(s) of the synergies between quercetin species and other co-existing nutrients/bioactives on the expression of miRNAs as well as the roles of miRNAs in overall nutritional control are critically discussed. PMID- 29446656 TI - Crohn's Disease Candidate Gene Alleles Predict Time to Progression from Inflammatory B1 to Stricturing B2, or Penetrating B3 Phenotype. AB - AIM: Crohn's disease (CD) patients are mostly diagnosed with the uncomplicated inflammatory form of disease; however, the majority will progress to complicated stricturing or penetrating disease over time. It is important to identify patients at risk for disease progression at an early stage. The aim of our study was to examine the role of 33 candidate CD genes as possible predictors of disease progression and their influence on time to progression from an inflammatory to a stricturing or penetrating phenotype. METHODS: Patients with an inflammatory phenotype at diagnosis were followed for 10 years and 33 CD associated polymorphisms were genotyped. To test for association with CD, 449 healthy individuals were analyzed as the control group. RESULTS: Ten years after diagnosis, 39.1% of patients had not progressed beyond an inflammatory phenotype, but 60.9% had progressed to complicated disease, with average time to progression being 5.91 years. Association analyses of selected single nucleotide polymorphisms (SNPs) confirmed associations with CD for 12 SNPs. Furthermore, seven loci were associated with disease progression, out of which SNP rs4263839 in the gene TNFSF15 showed the strongest association with disease progression and the frameshift mutation rs2066847 in the gene NOD2 showed the strongest association with time to progression. CONCLUSIONS: The results of our study identified specific genetic biomarkers as useful predictors of both disease progression and speed of disease progression in patients with CD. PMID- 29446657 TI - Health Risks among People with Severe Mental Illness in Psychiatric Outpatient Settings. AB - Life expectancy is greatly reduced in patients with schizophrenia, and cardiovascular diseases are a leading cause of mortality. The aim of this cross sectional study was to investigate the prevalence of overweight, obesity, and cardiovascular disease (CVD) risk and to investigate the relationships between self-rated health, sense of coherence, CVD risk, and body mass index (BMI) among people with severe mental illness (SMI) in psychiatric outpatient settings. Nearly 50% of the participants were exposed to moderate/high risk of CVD and over 50% were obese. The results showed no statistically relationships between the subjective and objective measures (Bayes factor <1) of health. The integration of physical health into clinical psychiatric nursing practice is vital. PMID- 29446658 TI - Post-concussive symptoms after a mild traumatic brain injury during childhood and adolescence. AB - OBJECTIVE: Mild traumatic brain injury (mTBI) is common injury during childhood and adolescence but the long-term outcomes are poorly understood. This study examined post-concussive symptoms and behavioural outcomes in children and adolescents up to 24 months post-mTBI. METHOD: Parents of children aged 8-15 years with mTBI completed the BASC-2 and Rivermead Post-Concussion Symptoms Questionnaire at baseline, 1-, 6-, 12- and 24 months post-injury. An age-matched traumatic brain injury-free cohort was recruited and assessed at 12- and 24 months. RESULTS: PCSs decreased significantly over the first 12 months post injury. At 12- and 24 months post-injury, the mTBI group reported more PCSs and behavioural symptoms compared to controls. Parents of children with mTBI were more likely to report >=4 problematic PCS symptoms (28% at both time points) compared to controls (7.7% and 1.7% at 12 and 24 months, respectively). The mTBI group was 4.63 times more likely to have four or more ongoing PCS symptoms at 12 months post-injury compared to controls. Headache was the most common acute post injury symptom (55%), while the most commonly reported persistent symptoms were irritability, frustration, forgetfulness and fatigue. CONCLUSIONS: PCSs are common 2 years post-mTBI in childhood or adolescence. Given this, additional intervention and support is needed for families post-injury.

AB - BACKGROUND AND AIM: This study was designed to explore the relationship between the brain-derived neurotrophic factor (BDNF) Val66Met polymorphism and antidepressants' efficacy in the Chinese Han population with generalized anxiety disorder (GAD). MATERIALS AND METHODS: We recruited 206 patients who met the diagnostic criteria for GAD into the test group, and assigned 209 healthy participants to the control group. All participants were genotyped for the BDNF Val66Met polymorphism. GAD patients were treated with escitalopram or extended release venlafaxine. We used the Hamilton Rating Scale for Anxiety (HAM-A) to assess the response to 8-weeks of antidepressant treatment for GAD. RESULTS: We did not identify any significant differences in the allelic or genotype frequencies of the BDNF Val66Met polymorphism between the test and control group. Furthermore, we did not detect any significant difference in the allele or genotype frequency of BDNF Val66Met between patients with different treatment responses. Finally, we did not detect any significant difference in the HAM-A score reduction rate among patients with different genotypes, gender, or treatment drugs. CONCLUSIONS: No significant difference was found in the BDNF Val66Met polymorphism between patients with GAD and healthy controls, nor was this polymorphism significantly associated with antidepressant drug efficacy for GAD.

AB - Plasma triglyceride (TG) levels show a clear daily rhythm, however, thus far it is still unknown whether this rhythm results from a daily rhythm in TG production, TG uptake or both. Previous studies have shown that feeding activity affects plasma TG concentrations, but it is not clear how the daily rhythm in feeding activity affects plasma TG concentrations. In the present study, we measured plasma TG concentrations and TG secretion rates in rats at 6 Zeitgeber times to investigate whether plasma TG concentrations and TG secretion show a daily rhythm. We found that plasma TG concentrations and TG secretion show a significant day/night rhythm. Next, we removed the daily rhythm in feeding behavior by introducing a 6-meals-a-day (6M) feeding schedule to investigate whether the daily rhythm in feeding behavior is necessary to maintain the daily rhythm in TG secretion. We found that the day/night rhythm in TG secretion was abolished under 6M feeding conditions. Hepatic apolipoprotein B (ApoB) and microsomal TG transfer protein (Mttp), which are both involved in TG secretion, also lost their daily rhythmicity under 6M feeding conditions. Together, these results indicate that: (1) the daily rhythm in TG secretion contributes to the formation of a day/night rhythm in plasma TG levels and (2) a daily feeding rhythm is essential for maintaining the daily rhythm in TG secretion.

Partly due to the negative connotation that this disease carries in religiously conservative areas, HIV-related stigma remains a critical barrier to HIV care in the South. However, spirituality is a well-documented, effective coping mechanism among persons living with HIV/AIDS (PLWH). The purpose of this study was to examine the relationship between HIV-related stigma and spiritual well-being among a sample of PLWH (n = 216) in Appalachian counties of Tennessee and Alabama using the HIV Stigma Scale and the Spiritual Well-being Scale. Overall, disclosure of HIV status was the most highly reported stigma concern. Women reported higher levels of stigma and religious well-being than men. While existential well-being was negatively correlated with stigma, no significant overall correlation was found between religious well-being and stigma. Our findings reveal the importance of defining theology and differentiating between cultural religious conditioning and internalized beliefs. PMID- 29446662 TI - Parents' Knowledge and Beliefs about the Impact of Exposure to Media Violence on Children's Aggression. AB - The current study aimed to assess Jordanian parents' knowledge and beliefs about the effects of violent media on children's aggressive behavior. A sample of 262 parents of children aged 6-11 years completed a Media Quotient questionnaire about children's media habits, media effects, and children's aggressive behavior. Parents reported that their children spend an average of 4.83 h (SD = 2.12) watching TV, 3.20 h (SD = 2.29) playing video games, 1.07 h (SD = 0.88) listening to music, and only 0.52 min (SD = 0.67) reading for pleasure per day. Parents have a moderate level of knowledge about the media effect (M = 15.49, SD = 3.439). Children of parents who have adequate knowledge about the media effect, spend less time watching TV (r = -.355, p < .001), playing video games (r = .265, p < .001), and listening to music (r = -.347, p < .001). Ninety-two percent (n = 241) of parents were concerned about the amount of sexual and of violent content their children see in movies or on TV. Children who spend more time playing video games (r = -.201, p = .004) show aggressive relational behavior. This study suggests that increasing parents' knowledge of media of evidence-based programs may have a protective effect on children's behavior. PMID- 29446663 TI - Editor's presentation. PMID- 29446666 TI - The Impact of Climate Change on Raw and Untreated Wastewater Use for Agriculture, Especially in Arid Regions: A Review. AB - Climate change is one of the major challenges of our time that pose unprecedented stress to the environment and threats to human health. The global impacts of climate change are vast, spanning from extreme weather events to changes in patterns and distribution of infectious diseases. Lack of rainfall associated with higher temperatures has a direct influence on agricultural production. This is compounded by a growing population forecasted to expand further with increasing needs for food and water. All this has led to the increasing use of wastewater worldwide. In this review, we more specifically discuss the use of untreated wastewater in agriculture in the Middle East and North Africa (MENA) countries, the most arid region in the world. This presents challenges for agriculture with respect to water availability and increasing wastewater use in agri-food chain. This in turn exerts pressures on the safety of food raised from such irrigated crops. Current practices in the MENA region indicate that ineffective water resource management, lack of water quality policies, and slow paced wastewater management strategies continue to contribute to a decline in water resources and an increased unplanned use of black and graywater in agriculture. Radical actions are needed in the region to improve water and wastewater management to adapt to these impacts. In this regard, the 2006 WHO guidelines for the use of wastewater contain recommendations for the most effective solutions. They provide a step-by-step guide for series of appropriate health protection measures for microbial reduction targets of 6 log units for viral, bacterial, and protozoan pathogens, but these need to be combined with new varieties of crops that are drought and pest resistant. More research into economic local treatment procedures for wastewater in the region is warranted. PMID- 29446667 TI - Safety of Administering Furosemide During Nuclear Diuretic Renography in Patients With Sulfonamide Allergies. AB - OBJECTIVE: We reviewed the safety of nuclear diuretic renography with furosemide in patients with sulfonamide allergies. The electronic health record was used to uncover any drug effects reported within 30 days of diuretic renograms performed between January 2009 and December 2015. CONCLUSION: Eighty-three of 1103 (7.5%) diuretic renograms were performed on patients with sulfonamide allergies. Two instances of minor rash occurred. No serious reactions occurred. Furosemide is associated with an extremely low risk of minor reactions in patients with sulfonamide allergies. PMID- 29446668 TI - Improved Opacification of a Suboptimally Enhanced Pulmonary Artery in Chest CT: Experience Using a Dual-Layer Detector Spectral CT. AB - OBJECTIVE: The objective of our study was to evaluate the quality of virtual monoenergetic imaging (VMI) from dual-layer detector spectral CT and the effect of virtual monoenergetic images obtained at low energies on the detection of pulmonary embolism (PE) in patients with a suboptimally enhanced pulmonary artery on chest CT. MATERIALS AND METHODS: Of 1552 consecutive chest CT examinations performed with dual-layer detector spectral CT using a routine protocol with a tube voltage of 120 kVp, 79 examinations with suboptimal enhancement of the pulmonary artery (i.e., mean attenuation of pulmonary artery <= 180 HU) were included. The mean attenuation of the pulmonary artery, noise, contrast-to-noise ratio (CNR), and signal-to-noise ratio (SNR) of virtual monoenergetic images obtained at 40-200 keV were compared with those of the conventional 120-kVp images. The virtual monoenergetic images with the best CNR were compared with the 120-kVp images with regard to subjective image quality and diagnostic accuracy for detecting PE. RESULTS: Sufficient attenuation of the pulmonary artery (> 180 HU) was obtained using VMI for 78 of the 79 examinations. The noise levels of the virtual monoenergetic images were gradually increased with decreasing energy level (i.e., kiloelectron volt setting). The CNR and SNR of virtual monoenergetic images at 40-65 keV were significantly higher (both, p < 0.001) than the CNR and SNR of the 120-kVp images. The CNR was the highest at 40 keV for all cases. Diagnostic accuracy for detecting PE was significantly higher for 40-keV images (reader 1: AUC = 0.992, p = 0.033; reader 2: AUC = 0.986, p = 0.043) than for 120 kVp images (reader 1, AUC = 0.911; reader 2, AUC = 0.933). The subjective quality was not different between these two images. CONCLUSION: In chest CT examinations in which the pulmonary artery is suboptimally enhanced, obtaining virtual monoenergetic images at a low energy setting using dual-layer detector spectral CT allows sufficient attenuation of the pulmonary artery to be achieved while preserving image quality and increasing diagnostic performance for detecting PE. PMID- 29446669 TI - Segmental Arterial Mediolysis: Abdominal Imaging of and Disease Course in 111 Patients. AB - OBJECTIVE: The purpose of this study is to identify the imaging characteristics of segmental arterial mediolysis (SAM) at presentation and establish the longitudinal course of disease. MATERIALS AND METHODS: We retrospectively identified patients with SAM at a single institution from 2000 through 2015. Diagnosis was based on published guidelines with multidisciplinary consensus. Imaging studies obtained at initial evaluation were reviewed to evaluate imaging findings and vascular territory distribution. All subsequent follow-up imaging studies were reviewed to assess for progression, stability, or regression. RESULTS: We identified 111 patients (79 men and 32 women; median age, 51 years) who met the diagnostic criteria for SAM. Abdominal pain was the most common presentation (74%), followed by flank pain (21%). SAM most commonly affected the renal arteries (47%), superior mesenteric artery (46%), celiac trunk (46%), hepatic artery (23%), iliac arteries (18%), and splenic artery (14%). The most common imaging findings were dissection (86%), aneurysm (57%), beading or webs (28%), occlusion (19%), and a rind or wall thickening (15%). The 247 available follow-up imaging studies for 97 patients (median follow-up, 12 months) showed progression in 19 patients (20%), with either stability or regression observed in the remaining patients. CONCLUSION: SAM most commonly affects the renal arteries, superior mesenteric artery, and celiac artery. Dissections and aneurysms are the most common imaging findings. Follow-up imaging studies show stability or regression in most patients. PMID- 29446670 TI - Diagnostic Performance of Margin Features in Thyroid Nodules in Prediction of Malignancy. AB - OBJECTIVE: The purpose of this study was to evaluate thyroid nodule margins for specific morphologic features and determine the diagnostic performance of these features in differentiating papillary carcinoma from benign thyroid nodules. MATERIALS AND METHODS: Nodules measuring 1-3 cm in largest diameter that had been evaluated with high-resolution ultrasound (12-18 MHz) and ultrasound-guided biopsy with definitive pathologic diagnosis were analyzed. Three blinded board certified readers evaluated high-resolution images of each nodule for jagged edges, lobulated borders, and curved borders along their margins. Reader interpretations were correlated with the pathologic diagnosis to determine the diagnostic performance of each feature. A board-certified pathologist analyzed 10 randomly selected nodules with jagged edges by slide review to evaluate for structural correlation with the imaging finding. RESULTS: The diagnostic performance of jagged edges in papillary carcinoma of the thyroid was 67.4% sensitive and 78.3% specific (odds ratio, 7.44; p < 0.001) for malignancy. Jagged edges correlated with infiltrative variant expansion at slide review. Lobulated borders had sensitivity of 76.1% and specificity of 60.9% for papillary carcinoma (odds ratio, 4.95; p = 0.001) for malignancy. Curved borders were not a significant predictor of papillary carcinoma. CONCLUSION: Jagged edges and lobulated borders of thyroid nodule margins are statistically significant predictors of papillary carcinoma of the thyroid. Jagged edges correlate with infiltrative-type expansion and may be useful predictors of more aggressive papillary carcinomas. PMID- 29446671 TI - Unenhanced MRI as an Alternative to 99mTc-Labeled Dimercaptosuccinic Acid Scintigraphy in the Detection of Pediatric Renal Scarring. AB - OBJECTIVE: The purpose of this study was to determine whether unenhanced MRI without sedation is a feasible substitute for dimercaptosuccinic acid (DMSA) scintigraphy in the detection of renal scars in pediatric patients. SUBJECTS AND METHODS: Patients scheduled for 99mTc-labeled DMSA scintigraphy for assessment of possible renal scars were recruited to undergo unenhanced MRI (free-breathing fat suppressed T2-weighted single-shot turbo spin-echo and T1-weighted gradient-echo imaging, 13 minutes' total imaging time). Scintigraphic and MRI studies were evaluated by two independent blinded specialty-based radiologists. For each imaging examination, readers identified scars in upper, middle, and lower kidney zones and rated their diagnostic confidence and the quality of each study. The scintigraphic readers' consensus score opinion for the presence of scars was considered the reference standard. RESULTS: DMSA scintigraphy showed scarring in 19 of the 78 (24.4%) evaluated zones and MRI in 18 of the 78 (23.1%). The two MRI readers found mean sensitivities of 94.7% and 89.5%, identical specificities of 100%, and diagnostic accuracies of 98.7% and 97.4%. Interobserver agreement was 98.7% for MRI and 92.3% for DMSA scintigraphy. The MRI readers were significantly more confident in determining the absence rather than the presence of scars (p = 0.02). MRI readers were more likely to rate study quality as excellent (84.6%) than were the scintigraphic readers (57.7%) (p = 0.024). CONCLUSION: Unenhanced MRI has excellent sensitivity, specificity, diagnostic accuracy, and interobserver agreement for detecting renal scars in older children who do not need sedation. It may serve as a substitute modality, especially when DMSA is not available. PMID- 29446672 TI - Choledochal Malformations: Surgical Implications of Radiologic Findings. AB - OBJECTIVE: The purpose of this article is to review the relevant pathophysiologic features, appearances, and surgical implications of choledochal malformations. CONCLUSION: Choledochal malformations, colloquially called choledochal cysts, initially described in 1723, have been recategorized multiple times, the most widely accepted being the Todani classification based on morphologic features and location. Although readily applied to imaging findings, this classification system does not correlate well with clinical and surgical management. In 2004, Visser and colleagues proposed an alternative that emphasized the etiologic factors, imaging appearance, and treatment approach. PMID- 29446673 TI - A Systematic Review of Fatigue in Radiology: Is It a Problem? AB - OBJECTIVE: The purpose of this study was to review current literature regarding radiologist fatigue. MATERIALS AND METHODS: A literature search was performed using PubMed. Key words and Medical Subject Heading terms were used to generate refined queries with inclusion and exclusion criteria, focusing on fatigue and error. Results were selected according to these criteria: examined radiologist fatigue and radiologic error stemming from fatigue; experimental results measured as accuracy, error, or performance; and peer-reviewed publication. The risk of bias was addressed by including both quantitative and qualitative studies. RESULTS: Twenty-seven articles were included, mainly primary research articles. Common outcome measures included subjective self-reports and tests to measure eyestrain. Reaction time was also recorded, accounting for variables such as age and experience. One group recommended that guidelines should be implemented regarding number of hours worked. Most recommended ergonomic interventions, proposing the implementation of tools to measure and standardize fatigue and optimize workflow, in conjunction with considering radiologists individually. Education in appropriate viewing habits and breaks were also suggested. Only one study with seven participants recommended that radiologists should sleep well to improve their performance and overall well-being, despite the undeniable evidence that radiologists are fatigued. CONCLUSION: Fatigue is present in radiology and affects diagnostic accuracy. PMID- 29446674 TI - Intravoxel Incoherent Motion MRI of Rectal Cancer: Correlation of Diffusion and Perfusion Characteristics With Prognostic Tumor Markers. AB - OBJECTIVE: The objective of our study was to evaluate the intravoxel incoherent motion (IVIM)-DWI derived parameters and their relationships with tumor prognostic markers using 3-T MRI in patients with rectal cancer. SUBJECTS AND METHODS: Fifty-two patients with histopathologically proven rectal cancer who underwent preoperative pelvic MRI were prospectively enrolled in this study. Diffusion and perfusion parameters including the apparent diffusion coefficient (ADC), pure diffusion coefficient, perfusion fraction, and pseudodiffusion coefficient derived from IVIMDWI were independently measured by two radiologists. Comparisons of IVIM-DWI-derived parameters in patients with different tumor prognostic markers were made using the independent-samples t test, ANOVA, and Mann-Whitney U test. The correlations between IVIM-DWI-derived parameters and tumor grade and tumor stage were further evaluated using Spearman correlation analysis. Interobserver agreement was evaluated using the intraclass correlation coefficient (ICC). RESULTS: Excellent interobserver reproducibility was obtained for the IVIM-DWI-derived parameters (range of ICCs with 95% limits of agreement = 0.9309-0.9948, which is narrow). ADC, pseudodiffusion coefficient, and perfusion fraction tended to rise with greater tumor differentiation (r = 0.520, p < 0.001; r = 0.447, p = 0.001; r = 0.354, p = 0.010, respectively). The pure diffusion coefficient and pseudodiffusion coefficient showed a trend of decreasing with increasing tumor stages (r = 0.479, p < 0.001; r = 0.517, p < 0.001). The group of patients with extramural vascular invasion (EMVI) showed lower pseudodiffusion coefficient values than the group of patients with no EMVI (p < 0.05). CONCLUSION: IVIM-DWI-derived parameters in patients with rectal cancer, especially the pseudodiffusion coefficient, are associated with tumor grade and tumor stage and show statistically significant differences between subjects with EMVI and those without EMVI. IVIM-DWI-derived parameters would be helpful in predicting tumor aggressiveness and prognosis.

AB - OBJECTIVE: The objective of this article is to discuss the current treatment options for colorectal cancer (CRC) liver metastases and the role of ablation. CONCLUSION: A randomized control trial of ablation combined with chemotherapy showed improved overall survival compared with chemotherapy alone. Local recurrence rates are comparable to those associated with resection when ablative margins of more than 5 mm are achieved and target lesions are smaller than 3 cm. In patients with unresectable disease, ablation for curative intent should be considered. PMID- 29446676 TI - Advanced DWI Methods for the Assessment of Ischemic Stroke.

PMID- 29446677 TI - How to Integrate Cell-Free DNA Screening With Sonographic Markers for Aneuploidy: An Update. AB - OBJECTIVE: The sonologist detects a so-called "soft marker" during approximately 10% of routine second-trimester anatomy examinations and is often uncertain about what further management is appropriate. This article will specifically address the management of patients with sonographic markers for six common entities: choroid plexus cysts (CPCs), ventriculomegaly (VM), echogenic intracardiac focus (EIF), urinary tract dilation (UTD), fetal echogenic bowel (FEB), and femoral and humeral shortening. The use of cell-free DNA screening and its relationship to these sonographic findings will be reviewed. CONCLUSION: The era of ultrasound markers as a screen for fetal aneuploidy is coming to a close. The detection of these markers on an ultrasound examination should simply serve as a reminder to ensure that the patient was offered cell-free DNA screening or conventional analyte screening. Cell-free DNA testing is revolutionizing screening. With normal results on a cell-free DNA test, many isolated soft markers-including CPCs, EIF, mild rhizomelic limb shortening, and mild pyelectasis-are irrelevant from a genetic standpoint. However, further counseling and workup are indicated for VM, true FEB, femur or humerus length measurement that is less than 2.5 percentile value, and pyelectasis to evaluate for the nongenetic associations with these findings. Finally, cell-free DNA testing is currently a screening test; positive results require definitive diagnostic testing with amniocentesis or chorionic villus sampling. PMID- 29446678 TI - Interrater Agreement and Diagnostic Accuracy of a Novel Computer-Aided Detection Process for the Detection and Prevention of Retained Surgical Instruments. AB - OBJECTIVE: The purpose of this study is to evaluate the diagnostic accuracy of a process incorporating computer-aided detection (CAD) for the detection and prevention of retained surgical instruments using a novel nondeformable radiopaque MUTag. MATERIALS AND METHODS: A high-specificity CAD system was developed iteratively from a training set (n = 540 radiographs) and a validation set (n = 560 radiographs). A novel test set composed of 700 thoracoabdominal radiographs (410 with a randomly placed MUTag and 290 without a MUTag) was obtained from 10 cadavers embedded with confounding iatrogenic objects. Data were analyzed first by the blinded CAD system; radiographs coded as negative (n = 373) were then independently reviewed by five blinded radiologists. The reference standard was the presence of a MUTag. Sensitivity and specificity were calculated. Interrater agreement was assessed with Cohen kappa values. Mean (+/- SD) image analysis times were calculated. RESULTS: The high-specificity CAD system had one false-positive (sensitivity, 79.5% [326/410]; specificity, 99.7% [289/290]). A combination of the CAD system and one failsafe radiologist had superior sensitivity (98.5% [404/410] to 100% [410/410]) and specificity (99.0% [287/290] to 99.7% [289/290]), with 327 (47%) radiographs not requiring immediate radiologist review. Interrater agreement was almost perfect for all radiologist pairwise comparisons (kappa = 0.921-0.992). Cumulative mean image analysis time was less than one minute (CAD, 29 +/- 2 seconds; radiologists, 26 +/- 16 seconds). CONCLUSION: The combination of a high-specificity CAD system with a failsafe radiologist had excellent diagnostic accuracy in the rapid detection of a nondeformable radiopaque MUTag.

Gore and Associates), specifically made for transjugular intrahepatic portosystemic shunt (TIPS) creation, has significantly improved TIPS patency compared with bare metal stents. Post-TIPS hepatic encephalopathy (HE), however, remains relatively common after TIPS creation. We describe a technique to secondarily restrict a Viatorr stent-graft to treat post-TIPS refractory HE and maintain use of the Viatorr device. CONCLUSION: We show a simple technique to modify the Viatorr stent-graft for TIPS reduction. PMID- 29446680 TI - Initial Clinical Experience With an Inducible Magnetic Seed System for Preoperative Breast Lesion Localization. AB - OBJECTIVE: The purpose of this study is to evaluate a nonradioactive inducible magnetic seed system (Magseed, Endomag) for preoperative localization of nonpalpable breast lesions. CONCLUSION: All of the 73 seeds placed in the first 4 months of clinical use were successfully placed and all were successfully retrieved intraoperatively. The mean time from seed placement to surgery was 3 days. Early clinical experience suggests that Magseed is an effective and accurate means of preoperative breast lesion localization. PMID- 29446681 TI - Coronary CT Angiography: Use in Patients With Chest Pain Presenting to Emergency Departments. AB - OBJECTIVE: Previously published reports have shown that coronary CT angiography (CCTA) is a more efficient method of diagnosis than myocardial perfusion imaging (MPI) and stress echocardiography for patients presenting to emergency departments (EDs) with acute chest pain. In light of this evidence, the objective of this study was to examine recent trends in the use of these techniques in EDs. MATERIALS AND METHODS: The nationwide Medicare Part B databases for 2006-2015 were the data source. The Current Procedural Terminology, version 4, codes for CCTA, MPI, and stress echocardiography were selected. Medicare place-of-service codes were used to determine procedure volumes in EDs. Medicare specialty codes were used to ascertain how many of these examinations were interpreted by radiologists, cardiologists, and other physicians as a group. RESULTS: From 2006 to 2015, there was essentially no change in the number of MPI examinations performed in EDs for patients using Medicare (22,342 in 2006, 22,338 in 2015) or in the number of stress echocardiograms (3544 in 2006, 3520 in 2015). By contrast, the number of CCTA examinations increased rapidly, from 126 in 2006 to 1919 in 2015 (compound annual growth rate, 35%). Despite this rapid growth, patients in EDs underwent 11.6 times as many MPI as CCTA examinations in 2015. In that last year of the study, radiologists interpreted 78% of ED MPI and 83% of ED CCTA examinations. CONCLUSION: Use of CCTA in EDs has increased rapidly, but far more MPI examinations are still being performed. This finding suggests that recently acquired evidence is not yet being fully acted upon. PMID- 29446682 TI - Fetal Urinary Tract Anomalies: Review of Pathophysiology, Imaging, and Management. AB - OBJECTIVE: Common fetal anomalies of the kidneys and urinary tract encompass a complex spectrum of abnormalities that can be detected prenatally by ultrasound. Common fetal anomalies of the kidneys and urinary tract can affect amniotic fluid volume production with the development of oligohydramnios or anhydramnios, resulting in fetal pulmonary hypoplasia and, potentially, abnormal development of other fetal structures. CONCLUSION: We provide an overview of common fetal anomalies of the kidneys and urinary tract with an emphasis on sonographic patterns as well as pathologic and postnatal correlation, along with brief recommendations for postnatal management. Of note, we render an updated classification of fetal abnormalities of the kidneys and urinary tract based on the presence or absence of associated urinary tract dilation. In addition, we review the 2014 classification of urinary tract dilation based on the Linthicum multidisciplinary consensus panel. PMID- 29446683 TI - Three-Dimensional Radial VIBE Sequence for Contrast-Enhanced Brain Imaging: An Alternative for Reducing Motion Artifacts in Restless Children. AB - OBJECTIVE: The purpose of this study was to evaluate the usefulness of radially sampled 3D fat-suppressed T1-weighted gradient-echo sequences (radial volumetric interpolated breath-hold examination [radial VIBE]) for contrast-enhanced brain MRI of children through comparison with a magnetization-prepared rapid acquisition gradient-echo (MP-RAGE) sequence. MATERIALS AND METHODS: Sixty-five consecutive contrast-enhanced brain MRI examinations performed with axial MP-RAGE and radial VIBE sequences were included. For quantitative analysis, coefficients of variation of gray matter and white matter and CSF and relative contrast between tissue types (gray matter and white matter, gray matter and CSF, and white matter and CSF) for each sequence were calculated. For qualitative assessment, motion, pulsation artifacts, overall image quality, and lesion conspicuity were retrospectively scored on a 5-point scale. Quantitative and qualitative subgroup analyses were performed for patients with serious motion artifacts. RESULTS: Images obtained with the radial VIBE sequence had fewer motion and pulsation artifacts than those obtained with the MP-RAGE sequence (MP RAGE vs radial VIBE motion score, 3.57 +/- 1.00 vs 4.52 +/- 0.51; pulsation score, 3.57 +/- 0.60 vs 4.91 +/- 0.21; all p < 0.001). Among 25 images with serious motion artifacts, radial VIBE images had significantly higher scores for all qualitative parameters, including overall image quality, than did MP-RAGE images (overall image quality for MP-RAGE vs radial VIBE, 2.63 +/- 0.82 vs 3.42 +/- 0.55, p < 0.001). CONCLUSION: The study showed that a radial fat-suppressed T1-weighted gradient-echo sequence is a viable alternative to conventional cartesian acquisition for contrast-enhanced brain imaging of restless children. PMID- 29446684 TI - Acute Nonhemorrhagic Adrenal Infarction in Pregnancy: 10-Year MRI Incidence and Patient Outcomes at a Single Institution. AB - OBJECTIVE: The purpose of this study was to retrospectively investigate the MRI incidence of nonhemorrhagic adrenal infarction in pregnant women undergoing MRI evaluation of acute abdominal or flank pain, assess the MRI features quantitatively, and report patient outcomes. MATERIALS AND METHODS: All abdominal MRI examinations of pregnant women with acute pain at one institution from May 2005 to April 2015 were reviewed. The adrenals were evaluated for abnormal morphologic and signal intensity characteristics described in the literature characterizing nonhemorrhagic adrenal infarction and were compared with the contralateral adrenal by paired t tests. The findings were correlated with clinical presentation. Patient demographics and outcomes were gathered from the medical record. RESULTS: Findings of nonhemorrhagic adrenal infarction were present in 5 of 379 (1.3%) examinations of four pregnant patients (mean age, 28 years; range, 20.8-33.9 years; mean gestational age, 26 weeks; range, 16-35 weeks). MRI features included lengthening (mean, 39.8 versus 21.2 mm) (p = 0.005) and increased T2 signal intensity (p = 0.001) of the infarcted adrenal with surrounding edema and without T1 signal intensity suggesting hemorrhage. No alternative diagnosis was identified. All patients presented with severe acute abdominal or flank pain on the same side as the MRI findings, tenderness to palpation, and mild leukocytosis. All women delivered healthy infants. CONCLUSION: Unilateral nonhemorrhagic adrenal infarction was identified in 1.3% of abdominal MRI examinations performed for pregnant women with acute abdominal or flank pain. Knowledge of the MRI characteristics of this entity is important for recognizing it and may prevent further potentially invasive tests, procedures, or missed diagnoses. PMID- 29446685 TI - Inactivation of Salmonella and Surrogate Bacteria on Cashews and Macadamia Nuts Exposed to Commercial Propylene Oxide Processing Conditions. AB - Propylene oxide (PPO), a chemical fumigant, has been validated to reduce Salmonella on bulk almonds but has not been evaluated for other tree nuts. There is a need to identify nonpathogenic surrogate microorganisms whose inactivation is comparable to that of Salmonella to assure effective PPO processing parameters in different packaging configurations without introducing Salmonella into the pasteurization facility. The objective of this research was to compare the reduction of Salmonella and three potential surrogate bacterial strains, Enterococcus faecium ATCC 8459, Pediococcus acidilactici ATCC 8042, or Staphylococcus carnosus ATCC 51365, on cashews and macadamia nuts processed by using PPO. Whole cashews and macadamia nuts were coinoculated with a five-strain cocktail of Salmonella and one surrogate, dried to the original water activity of 0.44 to 0.51 before being packaged in woven polypropylene bags (2.3 kg), and shipped overnight in Styrofoam containers under ambient conditions to a commercial facility for PPO treatment. Salmonella and surrogates were recovered by vigorous shaking in phosphate buffer (1:1, m/v), serial diluted, and plated onto tryptic soy agar with an overlay of xylose lysine Tergitol 4 for Salmonella or mannitol salt agar or bile esculin azide agar for each surrogate. The mean log reductions of Salmonella and each surrogate ( n = 18), within a sample and among all trials (three independent), were compared by using a matched pairs t test. Reduction in log CFU per gram of Salmonella was significantly greater than that of E. faecium on both macadamia nuts (7.3 +/- 0.19 versus 6.4 +/- 0.31) and cashews (5.4 +/- 0.15 versus 5.1 +/- 0.25) and significantly greater than P. acidilactici on both nuts (7.8 +/- 0.22 versus 6.3 +/- 0.33 on macadamia nuts and 4.9 +/- 0.22 versus 4.1 +/- 0.25 on cashews). Reduction of S. carnosus exceeded that of Salmonella. E. faecium and P. acidilactici may be considered as surrogates for Salmonella on whole macadamia nuts and cashews processed by using PPO. PMID- 29446686 TI - Survey of Foodborne Pathogens, Aerobic Plate Counts, Total Coliform Counts, and Escherichia coli Counts in Leafy Greens, Sprouts, and Melons Marketed in the United States. AB - The objective of this research was to assess the microbiological status of leafy greens, sprouts, and melons from U.S. markets. A total of 14,183 samples of leafy greens, 2,652 samples of sprouts, and 3,411 samples of melons were collected throughout the United States from 2009 to 2014. The samples were analyzed for aerobic plate counts, total coliform counts, Escherichia coli counts, and the presence and levels of Salmonella, Shigella, Listeria monocytogenes, and Shiga toxin-producing E. coli (STEC), depending on the year and type of produce. Among the leafy greens, no E. coli O157:H7 or non-O157 STEC were detected from iceberg lettuce samples. The overall prevalences of Salmonella, E. coli O157:H7, non-O157 STEC, and L. monocytogenes in the 14,183 samples of leafy greens were 0.05, 0.01, 0.07, and 0.11%, respectively. Among sprout samples, no Salmonella or E. coli O157:H7 was detected, and the overall prevalences of non-O157 STEC and L. monocytogenes were 0.04 and 0.11%, respectively. Among melon samples, no Salmonella was detected from cucumbers, no L. monocytogenes was detected from cantaloupes, and the overall prevalences of Salmonella and L. monocytogenes were 0.12 and 0.23%, respectively. L. monocytogenes levels were 0.4 to 1,470 most probable number (MPN)/g in leafy greens, 0.36 to 1,100 MPN/g in sprouts, and <0.03 to 150 MPN/g in melons, and most positive samples had low levels of these pathogens. The isolates from these foods were very diverse genetically. Foodborne pathogens, including Salmonella, STEC, and L. monocytogenes, had relatively low prevalences in the produce surveyed. Because these foods are usually consumed raw, measures should be taken to significantly minimize the presence and levels of human pathogens. PMID- 29446687 TI - icaA Gene of Staphylococcus aureus Responds to NaCl, Leading to Increased Biofilm Formation. AB - The objective of this study was to elucidate the role of the icaA gene in biofilm formation of Staphylococcus aureus exposed to NaCl. The icaA-deletion mutant of S. aureus ATCC 13565 was constructed with the temperature-sensitive plasmid pIMAY. Microtiter plate assays were performed to confirm biofilm formation for both the wild type and the mutant at 0% (control), 2, 4, and 6% NaCl. The microtiter plate assay revealed that biofilm formation by the wild type increased ( P < 0.05) as NaCl concentration increased, but biofilm formation of the mutant was not affected by NaCl concentration. Biofilm formation by the mutant was lower ( P < 0.05) than that by the wild type. These results indicate that icaA plays an important role in biofilm formation by S. aureus when the pathogen is exposed to NaCl. PMID- 29446688 TI - Chronic Thromboembolic Pulmonary Hypertension. PMID- 29446689 TI - Platelets and vascular integrity. AB - Platelets patrol the vasculature and adhere at sites of vascular damage after trauma to limit blood loss. In recent years, however, it has become clear that platelets also contribute to pathophysiologic processes such as thrombosis, atherosclerosis, stroke, sepsis and many more. An exciting new role for them is in non-classical hemostasis to prevent bleeding in the inflamed vasculature. Recent studies suggest that GPVI, CLEC-2, integrin alphaIIbbeta3 (GPIIb/IIIa), and the content of platelet alpha- and dense granules are important players in this process. This review summarizes the current knowledge about how platelets prevent vascular integrity during inflammation in the skin, lung, and the ischemic brain and their organ-specific role. PMID- 29446690 TI - Perineurial-like Cells and EMA Expression in the Suprachoroidal Region of the Human Eye. AB - The suprachoroidal region of the eye comprises vascular channels, melanocytes, and thin fibroblasts with elongated cytoplasm that are positioned directly adjacent to the densely collagenous sclera. Morphological similarities between these suprachoroidal fibroblasts and arachnoid cells and perineurial cells have been recognized, but whether these fibroblasts have a perineurial cell-like immunophenotype is not known. To further examine the relationship of these three cell types, we investigated the comparative expression of epithelial membrane antigen (EMA), the tight junction protein claudin-1, glucose transporter-1 (Glut 1), and CD34 in suprachoroidal fibroblasts, arachnoid of the optic nerve sheath, and perineurium of ciliary nerves in eight human eye specimens. Granular, diffuse, and cytoplasmic EMA expression was seen in suprachoroidal fibroblasts, but this was not contiguous with the similar pattern of EMA expression in adjacent perineurium and arachnoid. CD34 expression in suprachoroidal fibroblasts was also seen, similar to arachnoid and perineurium. Claudin-1 and Glut-1 were not consistently expressed in suprachoroidal fibroblasts, distinguishing them from perineurial cells in particular and suggesting that these fibroblasts do not arise directly from adjacent arachnoid or perineurium. Nonetheless, the overlapping morphology and protein expression suggest phenotypic similarities in these cells that protect and support adjacent retina, optic nerve, and peripheral nerve. PMID- 29446692 TI - Can bracing help adults with chronic back pain and scoliosis? Short-term results from a pilot study. AB - BACKGROUND: Adult scoliosis is sometimes associated with back pain. Recently, the PeakTM Scoliosis Brace was designed to alleviate pain in adult patients with scoliosis. OBJECTIVES: To test the efficacy of the Peak Scoliosis Brace in reducing pain in adult scoliosis patients. STUDY DESIGN: Prospective experimental cohort study. METHODS: A total of 20 adult females with back pain secondary to idiopathic scoliosis were included. Patients were evaluated at baseline immediately before starting bracing and after 1 month. The brace had to be worn for at least 2 h per day. The outcome measures used were Graphical Rating Scale, Roland-Morris Questionnaire, Core Outcome Measurement Index, and Oswestry Disability Index. RESULTS: Worst pain, back pain, and leg pain significantly improved from 7.15 to 5.85, from 6.55 to 5.25, and from 5.65 to 3.55, respectively ( p < 0.05). A total of 75% of patients reported improved worst and leg pain, 65% improved back pain, 30% of patients achieved the minimal clinically significant difference of 2 points for worst pain, 60% for leg pain, and 25% for back pain. Roland-Morris Questionnaire and Core Outcome Measurement Index improved ( p < 0.05) and no differences were observed for Oswestry Disability Index. CONCLUSION: The Peak Scoliosis Brace led to some improvement of pain at 1 month in a group of adult women with scoliosis and chronic low back pain. The quality of life did not change significantly. Clinical relevance According to our data, the Peak Brace is helpful to quickly improve pain in patients with chronic low back pain secondary to scoliosis. To achieve this goal, it should be applied for at least 2 h per day. PMID- 29446691 TI - Early insights into the characteristics and evolution of clinical parameters in a cohort of patients prescribed sacubitril/valsartan in Germany. AB - OBJECTIVES: This study aimed to provide early insights into sacubitril/valsartan (sac/val) prescription patterns and the demographic and clinical characteristics of patients prescribed sac/val in primary care and cardiology settings in Germany. METHODS: The study used electronic medical records from the German IMS(r) Disease Analyzer database. Patients with >=1 prescription for sac/val during 1 January-31 December 2016 (n = 1643) were identified and followed up for <=12 months from first prescription. Patients with >=1 heart failure (HF) diagnosis during the study period, >=1 additional HF diagnosis in the full history of the database, and >=1 prescription for an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker and a beta-blocker during the study period, without a prescription for sac/val (n = 25,264), were included as a reference cohort. Changes in clinical parameters in the 12 months before and after sac/val initiation were investigated and compared with those from the PARADIGM-HF study. RESULTS: The characteristics of patients prescribed sac/val more closely resembled those of patients enrolled in PARADIGM-HF (e.g. younger age, higher proportion of men than women, lower systolic blood pressure) than patients in the reference cohort. Most patients were initiated on the lowest dose of sac/val irrespective of clinical setting. Significant decreases (p < 0.001) in NT-proBNP and glycated haemoglobin levels were observed following sac/val initiation. CONCLUSIONS: Patients prescribed sac/val had similar baseline demographics and clinical characteristics to those from PARADIGM-HF, and most patients were initiated on the lowest dose. Changes in clinical parameters before and after initiation mirrored findings from the PARADIGM-HF study. PMID- 29446693 TI - Hyperparathyroidism Mimicking Metastatic Bone Disease: A Case Report and Review of Literature. AB - Multiple osteolytic lesions are usually associated with metastatic involvement of the bone; however, metabolic bone diseases should also be included in the differential diagnosis. In this study, we describe a case of primary hyperparathyroidism (PHPT) with multiple osteolytic lesions that was diagnosed initially as having metastatic bone involvement. The laboratory results showed hypercalcemia and raised alkaline phosphatase along with fibrosis in the bone marrow biopsy with no increase in tumor markers and normal serum protein electrophoresis. The parathyroid hormone levels were high, which pointed toward a diagnosis of PHPT. Sestamibi scan revealed uptake at the level of the left inferior pole of the thyroid gland, which was suggestive of parathyroid adenoma. The possibility of hyperparathyroidism should be kept in mind when a patient presents with multiple osteolytic lesions and hypercalcemia. PMID- 29446694 TI - Experimental measurement of forces during percutaneous dilatational tracheostomy. AB - The measurement of mechanical effects associated with the dilatation phase of a percutaneous dilatational tracheostomy is of primary importance to identify the causes of major complications associated with this procedure, such as tracheal cartilage subluxation or fracture and bleeding. Such information can be very useful also for the design of better instruments and procedures. The aim of this study was to present a methodology to evaluate mechanical effects of the dilatation phase of a percutaneous dilatational tracheostomy on the tracheal rings and adjacent anatomical structures. Forces and moments were measured through a dilator instrumented with strain gauges. Two surgeons, with different levels of expertise, performed the percutaneous dilatational tracheostomy on a lifelike reproduction of an adult head, specifically designed for training professionals. The modified dilator was effective in measuring forces involved in the percutaneous dilatational tracheostomy without affecting the ability of the operator to perform the procedure. The main contribution to the insertion of the dilator was given by the axial force, defined as the force acting on the handle, compressing it (mean and peak force: 48.8 and 88.2 N for Surgeon 1, 31.3 and 82.8 N for Surgeon 2, respectively). The proposed method was effective in measuring differences between procedures performed by surgeons with different amounts of experience in terms of duration, forces applied and repeatability. In addition, it may have applications for use as a feedback for incorrect positioning or excessively variable pressure during the training of surgeons for the execution of percutaneous dilatational tracheostomy. PMID- 29446695 TI - Weight-shift ability significantly correlates with walking velocity in post-acute stroke patients. AB - The ability to shift weight toward the paretic leg has been considered an essential ability to restore independent walking for post-acute stroke patients. However, few data are available regarding the relationship between the weight shift ability and gait performance. No clear mechanism has been provided as to why and how the weight-shift ability improves walking performance in stroke patients. We therefore investigated changes in the weight-shift ability and kinematic and kinetic parameters of walking gait in post-stroke patients during rehabilitation. Eight male inpatients undergoing rehabilitation for moderate hemiplegia participated in this study. Measurements were taken every 4 weeks from when the participants were able to walk at least 10 m until they were discharged from the hospital. Our results demonstrated a significant overall correlation between the weight-shift ability and walking velocity, indicating that the improvement in the weight-shift ability toward the paretic leg by lateral tilting of the thorax is fundamentally important to improve walking velocity. We also found that the upward impulse and vertical ground reaction force exerted by the paretic leg were significantly correlated with the walking velocity to cope with the downward impulse due to gravity and to allow sufficient time to swing the non paretic leg forward during walking. Therefore, improvement in the weight-shift ability is crucial for restoration of walking velocity. We believe that weight shift training for the paretic leg while instructing the patients to laterally tilt the thorax should be advocated as an effective protocol during rehabilitation of post-acute stroke inpatients. PMID- 29446696 TI - Expression profiles of stress-related genes in islets from donors with progressively impaired glucose metabolism. AB - It is currently unknown how the islet transcriptional pattern changes as glucose metabolism deteriorates and progresses to fulminant type 2 diabetes (T2D). In this study, we hypothesized that islets from donors with elevated HbA1c levels, but not yet diagnosed with T2D, would show signs of cell stress on a transcriptional level. Laser capture microdissection and qPCR arrays including 330 genes related to mitochondria, oxidative stress, or the unfolded protein response were used to extract and analyze islets from organ donors with HbA1c <5.5% (37 mmol/mol), elevated HbA1c (6.0-6.5% (42-48 mmol/mol)), high HbA1c (>6.5% (48 mmol/mol)) or established T2D. Principal component analysis and hierarchical clustering based on the expression of all 330 genes displayed no obvious separation of the four different donor groups, indicating that the inter donor variations were larger than the differences between groups. However, 44 genes were differentially expressed (P < 0.05, false discovery rate <30%) between islets from donors with HbA1c <5.5% (37 mmol/mol) compared with islets from T2D subjects. Twelve genes were differentially expressed compared to control islets in both donors with established T2D and donors with elevated HbA1c (6.0-6.5% (42 48 mmol/mol)). Overexpressed genes were related mainly to the unfolded protein response, whereas underexpressed genes were related to mitochondria. Our data on transcriptional changes in human islets retrieved by LCM from high-quality biopsies, as pre-diabetes progresses to established T2D, increase our understanding on how islet stress contributes to the disease development. PMID- 29446697 TI - Psychedelics and the essential importance of context. AB - Psychedelic drugs are making waves as modern trials support their therapeutic potential and various media continue to pique public interest. In this opinion piece, we draw attention to a long-recognised component of the psychedelic treatment model, namely 'set' and 'setting' - subsumed here under the umbrella term 'context'. We highlight: (a) the pharmacological mechanisms of classic psychedelics (5-HT2A receptor agonism and associated plasticity) that we believe render their effects exceptionally sensitive to context, (b) a study design for testing assumptions regarding positive interactions between psychedelics and context, and (c) new findings from our group regarding contextual determinants of the quality of a psychedelic experience and how acute experience predicts subsequent long-term mental health outcomes. We hope that this article can: (a) inform on good practice in psychedelic research, (b) provide a roadmap for optimising treatment models, and (c) help tackle unhelpful stigma still surrounding these compounds, while developing an evidence base for long-held assumptions about the critical importance of context in relation to psychedelic use that can help minimise harms and maximise potential benefits. PMID- 29446698 TI - Radiological fibrosis score is strongly associated with worse survival in rheumatoid arthritis-related interstitial lung disease. AB - OBJECTIVES: High-resolution computed tomography (HRCT) parenchymal patterns have been used to predict prognosis in patients with interstitial lung disease (ILD). In idiopathic pulmonary fibrosis, the fibrosis score (i.e. the combined extent of reticulation and honeycombing) has been associated with worse survival. This study aimed to identify HRCT patterns and patient characteristics that can predict poor prognosis in rheumatoid arthritis-related ILD (RA-ILD). METHODS: We retrospectively analysed 65 patients with newly diagnosed RA-ILD from 2007 to 2016 at Kurashiki Central hospital. Using univariate and bivariate Cox regression analysis, associations with mortality, were identified. RESULTS: During a median follow-up of 56.5 months, 16/65 (24.6%) patients died. Univariate analysis identified six significant poor prognostic factors: lower baseline % predicted forced vital capacity, total interstitial disease score, reticulation score, traction bronchiectasis score, fibrosis score, and definite UIP pattern. Fibrosis score remained to be an independently significant poor prognostic factor of survival on bivariate analysis. Patients with a fibrosis score >20% had higher mortality (HR, 9.019; 95% CI, 2.87-28.35; p < .05). CONCLUSION: This study showed that fibrosis score is strongly associated with worse survival in RA-ILD, and patients with fibrosis score >20% had a 9.019-fold increased risk of mortality. PMID- 29446699 TI - Investigating d-cycloserine as a potential pharmacological enhancer of an emotional bias learning procedure. AB - The partial N-methyl-D-aspartate receptor agonist d-cycloserine may enhance psychological therapies. However, its exact mechanism of action is still being investigated. Cognitive bias modification techniques allow isolation of cognitive processes and thus investigation of how they may be affected by d-cycloserine. We used a cognitive bias modification paradigm targeting appraisals of a stressful event, Cognitive Bias Modification-Appraisal, to investigate whether d cycloserine enhanced the modification of appraisal, and whether it caused greater reduction in indices of psychopathology. Participants received either 250 mg of d cycloserine ( n=19) or placebo ( n=19). As a stressor task, participants recalled a negative life event, followed by positive Cognitive Bias Modification-Appraisal training. Before and after Cognitive Bias Modification-Appraisal, appraisals and indices of psychopathology related to the stressor were assessed. Cognitive Bias Modification-Appraisal successfully modified appraisals, but d-cycloserine did not affect appraisals post-training. There were no post-training group differences in frequency of intrusions. Interestingly, d-cycloserine led to a greater reduction in distress and impact on state mood from recalling the event, and lower distress post-training was associated with fewer intrusions. Therefore, d-cycloserine may affect emotional reactivity to recalling a negative event when combined with induction of a positive appraisal style, but via a mechanism other than enhanced learning of the appraisal style. PMID- 29446700 TI - An interview-informed synthesized contingency analysis to inform the treatment of challenging behavior in a young child with autism. AB - PURPOSE: Experimental Functional analysis (EFA) is considered the "gold standard" of behavioural assessment and its use is predictive of treatment success. However, EFA has a number of limitations including its lengthy nature, the high level of expertise required, and the reinforcement of challenging behaviour. This study aimed to further validate a novel interview-informed synthesised contingency analysis (IISCA). METHODS: An open-ended interview and brief direct observation informed an IISCA for a young boy with autism who engaged in challenging behaviour. Resulting data supported the hypothesis that the target behaviour was multiply controlled by escape from demands and access to tangible items. An intervention comprised of most-to-least prompting, escape extinction, differential reinforcement and a high-probability instruction sequence was evaluated using a reversal design. RESULTS: This intervention reduced challenging behaviour to low levels and resulted in increased compliance. CONCLUSIONS: Findings support the status of the IISCA as a valid, practical, and effective process for designing function-based interventions. PMID- 29446702 TI - How Does Usage of Serotonin Noradrenaline Reuptake Inhibitors Affect Intraocular Pressure in Depression Patients? AB - PURPOSE: To evaluate anterior segment parameters and intraocular pressure (IOP) modifications in patients using serotonin noradrenaline reuptake inhibitors (SNRIs) due to major depressive disorder. METHODS: This cross-sectional study included 170 eyes of 85 subjects. All subjects were divided into three groups: group 1 included 44 healthy control subjects, group 2 included 22 patients receiving antidepressants for 1 week to 6 months, and group 3 included 19 patients receiving antidepressants for >6 months. All subjects underwent a detailed ophthalmologic examination, including gonioscopy. Anterior segments of all subjects were evaluated with the Scheimpflug system and pupil diameter (PD), central corneal thickness, anterior chamber depth (ACD), anterior chamber volume, and anterior chamber angle (ACA) measurements were enrolled. RESULTS: The median IOP was significantly lower in patients using antidepressants [16.0 (11.0-21.0) mmHg] than the control group [17.5 (12.0-21.0) mmHg] (P = 0.041). The PD was significantly larger in patients using antidepressants [3.56 (2.29-5.60) mm] than the control group [2.95 (2.00-4.40) mm] (P = 0.000). In the study group, PD was also significantly larger in patients using SNRIs for >=6 months [3.67 (2.38 5.08) mm] than <6 months [3.31 (2.29-5.60) mm] (P = 0.000). The median ACD was significantly lower in patients using antidepressants for >=6 months [3.21 (2.52 4.06) mm] than the control group [3.44 (2.63-4.29) mm] (P = 0.000). ACAs were measured between 25 degrees and 55 degrees by Scheimpflug imaging. CONCLUSIONS: Treatment of SNRIs causes mydriasis and decrease in width of ACD. These changes may not increase IOP as long as the patient has an open angle. SNRIs lead to decrease in IOP particularly in long-term usage. PMID- 29446701 TI - Endoscopic Excision of Benign Facial Masses in Children: A Review of Outcomes. AB - PURPOSE: Benign masses of the eyebrow and forehead are common in pediatric patients and can result in facial asymmetry, discomfort, or super-infection. Excision is classically conducted via an incision directly over the mass, which can produce sub-optimal cosmesis. Recently, an endoscopic approach using pediatric brow-lift equipment has been adopted. We reviewed our center's experience with endoscopic removal of benign facial lesions and compared these cases with an equivalent series of open cases. MATERIALS AND METHODS: A retrospective chart review was conducted to identify pediatric cases of endoscopic and open removal of benign eyebrow or forehead lesions at our institution from 2009 to 2016. Clinical and cosmetic outcomes were reviewed. RESULTS: A total of 40 endoscopic and 25 open cases of excision of benign facial lesions in children were identified. For the patients who underwent endoscopic excision, the majority (85%) presented with a cyst located at the eyebrow. Histologic examination revealed 36 dermoid cysts (90%), 2 epidermal cysts, and 2 pilomatrixomas. Of the 36 cases with post-operative follow-up, 32 patients (89%) had an uncomplicated recovery with good cosmesis. Two patients had an eyebrow droop that resolved without intervention. One patient had localized numbness overlying the site, but no motor deficits. One patient presented with a recurrent dermoid cyst that required open resection. For the patients who underwent open excision, the majority (52%) had dermoid cysts located at the eyebrow. Of the 22 cases with follow-up, 20 of the patients had an uncomplicated recovery (90%). Comparing the rate of complications, there was no statistically significant difference between the two groups (P = 1.0). CONCLUSION: Endoscopic excision of benign forehead and eyebrow lesions in pediatric patients is feasible and yields excellent cosmetic results. When compared with open excision, complication rates are similar between both approaches and a facial scar can be avoided with an endoscopic approach. PMID- 29446703 TI - Use of the 5-mm Endoscopic Stapler for Ligation of Fistula in Laparoscopic Assisted Repair of Anorectal Malformation. AB - OBJECTIVE: Laparoscopic anorectoplasty (LARRP) for the treatment of select anorectal malformations has gained popularity due to enhanced visualization of the fistula and the ability to place the rectum within the sphincter complex while minimizing division of muscles and the perineal incision. However, given the technical challenges and reported complications of ligation, a number of techniques have been described, including using clips, suture ligation, endoloops, or division without closure. We aimed to evaluate fistula closure and division for high imperforate anus using a 5-mm stapler (JustRight Surgical, Boulder, CO). MATERIALS AND METHODS: A retrospective chart review was performed on patients who underwent LAARP for imperforate anus between March 2015 and December 2016. RESULTS: Four patients underwent LAARP with division of the fistula using the 5-mm stapler. The average age was 3.2 months and average weight was 4.5 kg. The location of the fistula was rectoprostatic in 3 cases and rectobladder neck in 1 case. There were no complications. CONCLUSION: Division of a fistula at or above the level of the prostate can safely and effectively be performed with the 5-mm stapler. The stapler allows for division flush with the urethra or bladder ergonomically and quickly. PMID- 29446705 TI - Prospective Assessment of Rhinovirus Symptoms and Species Recurrence in Children With and Without an Acute Wheezing Exacerbation. AB - To assess if the difference in species-specific immune response to RV-C correlates with a higher frequency of reinfection, shorter time to reinfection, or different symptom severity than infections with RV-A or RV-B. Forty-three patients were enrolled of which 34 were successfully tracked longitudinally over 3 months, with nasal swabs and symptom questionnaires provided every 2 weeks to identify rhinovirus (RV) strains and the concurrent symptomatology. No difference was found in the time to reinfection with an RV species between RV-C and RV-A or RV-B (p = 0.866). There was a trend toward more rapid reinfection with the same species in RV-C than RV-A (55.1 days vs. 67.9 days), but this failed to reach statistical significance (p = 0.105). RV infections were generally associated with only minor symptoms, with rhinorrhea being the only significantly associated symptom (p = 0.01). RV-C was shown to have higher levels of lethargy and wheeze than other RV species. Time to reinfection with subsequent RV is not influenced by the species of the preceding RV. PMID- 29446704 TI - Effect of sodium molybdate supplementation on high concentrations of Cu in liver of yearling bulls. AB - AIM: To determine the impact of sodium molybdate treatment, given weekly, on concentrations of Cu in liver, activity of liver enzymes, and weight gain over 4 weeks, in yearling bulls with elevated concentrations of Cu in liver. METHODS: The study was carried on two commercial grazing farms in the Otago region of New Zealand in yearling Friesian bulls (n=150 on Farm A and n=49 on Farm B) with mean concentration of Cu in liver >3,000 umol/kg fresh weight. On Day 0, all animals were weighed and half were systematically allocated to treatment with sodium molybdate (3 mg/kg liveweight on Farm A and 7 mg/kg liveweight on Farm B); the remainder received no treatment (Control). Sodium molybdate was given as a drench weekly for 4 weeks and all animals were weighed again on Day 28. Ten animals on each farm (five from each treatment group) were systematically selected for blood sampling and liver biopsies on Days 0 and 28. Samples were analysed for concentrations of Cu in plasma, vitamin B12 in serum, activities of gamma glutamyl transferase, aspartate aminotransferase and glutamate dehydrogenase in serum, and concentrations of Cu and vitamin B12 in liver. Separate multivariable linear models were used to compare the change in outcome variables between Days 0 and 28 between bulls that had been drenched with sodium molybdate or not. RESULTS: On Farm A, mean concentrations of Cu in liver on Day 28, as a percentage of concentrations on Day 0, for the control group was 55 (95% CI=40-73)% and for the treatment group was 73 (95% CI=43-111)%. On Farm B, the equivalent mean for the control group was 75 (95% CI=42-131)% and for the treatment group was 85 (95% CI=38-134)%. The multivariable linear models indicated that the changes in concentrations of Cu in liver, activities of liver enzymes and weight gain between Days 0 and 28 did not differ between the bulls treated or not with sodium molybdate (p>0.18). CONCLUSIONS AND CLINICAL RELEVANCE: Treatment with sodium molybdate in one bolus at weekly intervals for 4 weeks did not affect concentrations of Cu in liver, activity of liver enzymes or weight gain in animals with high concentrations of Cu liver on two farms. PMID- 29446706 TI - A 3D finite element model of prophylactic vertebroplasty in the metastatic spine: Vertebral stability and stress distribution on adjacent vertebrae. AB - Background and Objective Patients with metastatically compromised vertebra can experience pathologic fracture with relevant neurological complications. Vertebroplasty is a low cost procedure and it can potentially prevent neurologic impairment if performed at an early stage. The aim of this study is to evaluate the effects of prophylactic vertebroplasty on stability of the metastatic spine and analyze load distribution at adjacent vertebrae. Setting A 3D finite element model of two spinal motion segments (L3-L5) was developed. A central core of elements was selected in L4 vertebral body and material properties of a lytic metastasis and successively PMMA were assigned. The model was settled in order to simulate a non-osteoporotic spine and an osteoporotic spine. Outcome Measures Vertebral stability was assessed by the measurement of vertebral bulge (VB) and vertebral height (VH) on L4. Load transfer on adjacent vertebrae was evaluated by observing the distribution of the von Mises stress on L3 and L5 endplates. Results The metastasis increased VB by 424% and VH by 626%, while prophylactic vertebroplasty decreased VB and VH by 99% and 95%, respectively, when compared to the normal/non-metastatic model. Prophylactic vertebroplasty increased the average von Mises stress of L3 lower endplate by 1.33% in the non-osteoporotic spine, while it increased to 16% in the osteoporotic model. Conclusions Prophylactic vertebroplasty could represent an interesting option to improve vertebral strength of metastatically compromised spine without excessively increasing the stresses on adjacent vertebrae in non-osteoporotic spine. PMID- 29446707 TI - Arsenic, cadmium, and mercury-induced hypertension: mechanisms and epidemiological findings. AB - Arsenic (As), cadmium (Cd), and mercury (Hg) are toxic elements widely distributed in the environment. Exposure to these elements was attributed to produce several acute and chronic illnesses including hypertension. The aim of this review is to provide a summary of the most frequently proposed mechanisms underlying hypertension associated with As, Cd, and Hg exposure including: oxidative stress, impaired nitric oxide (NO) signaling, modified vascular response to neurotransmitters and disturbed vascular muscle Ca2+ signaling, renal damage, and interference with the renin-angiotensin system. Due to the complexity of the vascular system, a combination rather than a singular mechanism needs to be considered. In addition, epidemiological findings showing the relationship between various biomarkers of metal exposure and hypertension are described. Given the complex etiology of hypertension, further epidemiological studies evaluating the roles of confounding factors such as age, gender, and life style are still necessary. PMID- 29446708 TI - Does local dynamic stability of kayak paddling technique affect the sports performance? A pilot study. AB - During competition, kayak athletes must optimally adapt to environmental factors (e.g. wind, waves) to achieve peak performance. However, the ability to adapt to such perturbations has never been assessed in kayak paddling. Therefore, the aim of the current study was to evaluate the local dynamic stability in sports technique of youth sprint kayak athletes. In a cross-sectional study, 14 healthy male athletes were recruited from an elite youth sprint kayak squad. During an incremental kayak ergometer test, mean power, heart rates and local dynamic technique stability of hands, arms, trunk and paddle were registered and the association with the athletes 2000 m free-water times were estimated using mixed models. The 2000 m free-water performance significantly predicted the paddles (p = .037) local dynamic stability whereas no association was found for the trunk or the upper extremity kinematics. In conclusion, kayak athletes with high performance capability over 2000 m paddling depict high local dynamic technique stability.

PMID- 29446710 TI - Early versus late cardiac remodeling during right ventricular pressure load and impact of preventive versus rescue therapy with endothelin-1 receptor blockers. AB - Pulmonary artery banding (PAB) causes right ventricular (RV) dysfunction, biventricular fibrosis, and apoptosis, which are attenuated by endothelin-1 receptor blockade (ERB). Little is known about the time course of remodeling and whether early versus late ERB confers improved outcome. PAB was performed in five groups of rabbits: Shams, 3-wk PAB (3W), 6-wk PAB (6W), 6-wk PAB + ERB administered from day 1 (6WERB1), and 6-wk PAB + ERB administered from day 21 (6WERB21). Biventricular development of profibrotic molecular signaling, fibrosis, apoptosis, and conductance catheter and echocardiography function were studied. Thirty-three rabbits [ n = 6-7 per group; 3.00 (0.23) kg, mean (SD)] developed half to full systemic RV pressures. Biventricular profibrotic signaling and collagen deposition [RV collagen: Shams 3.8 (0.58) vs. 3W 8.69 (2.52) vs. 6W 8.83 (4.02)%, P < 0.005] and apoptosis [RV: Shams 8.32 (3.2) vs. 3W 55.95 (47.55) vs. 6W 38.85 (17.26) apoptotic cells per microfield, P < 0.0005] increased with PAB. Early and late ERB attenuated fibrosis [RV: 6WERB1 5.55 (1.18), 6WERB21 5.63 (0.72)%] and apoptosis [RV: 6WERB1 11.1 (5.25), 6WERB21 20.24 (7.16) apoptotic cells per microfield, P < 0.0001 vs. 6W]. RV dimensions progressively increased at 3W and 6W and decreased with early ERB [end-diastolic dimensions: Shams 0.4 (0.13) vs. 3W 0.55 (0.78) vs. 6W 0.78 (0.25) vs. 6WERB1 0.71 (0.26) vs. 6WERB21 0.49 (0.23) cm, P < 0.05]. Despite increased RV contractility with PAB [RV end systolic pressure-volume relationship: Shams 3.76 (1.76) vs. 3W 12.21 (3.44) vs. 6W 19.4 (6.88) mmHg/ml], biventricular function and cardiac output [Shams 196.1 (39.73) vs. 3W 149.9 (34.82) vs. 6W 151 (31.69) ml/min] worsened in PAB groups and improved with early and late ERB [6WERB1 202.8 (26.8), 6WERB21 194.8 (36.93) ml/min, P < 0.05 vs. PAB]. In conclusion, RV pressure overload induces early biventricular fibrosis, apoptosis, remodeling, and dysfunction that worsens with persistent RV hypertension. This remodeling is attenuated by early and late ERB. NEW & NOTEWORTHY Our results in a rabbit model of progressive right ventricular (RV) pressure loading indicate that biventricular fibrosis, apoptosis, and dysfunction are already present when RV hypertension is reached at 3 wk of progressive pulmonary artery banding. These findings worsen with persistent RV hypertension to 6 wk and are attenuated with both early and late endothelin-1 receptor blockade, with some advantages to early therapy. These findings highlight the role of endothelin-1 in driving biventricular remodeling secondary to RV hypertension and suggest that early therapy with an endothelin-1 receptor blocker may be beneficial in attenuating biventricular remodeling but that late therapy is also effective. PMID- 29446711 TI - Neurophysiological adaptations in the untrained side in conjunction with cross education of muscle strength: a systematic review and meta-analysis. AB - We reviewed the evidence from randomized controlled trials (RCTs) focusing on the neurophysiological adaptations in the untrained side associated with cross education of strength (CE) and pooled data into definite effect estimates for neurophysiological variables assessed in chronic CE studies. Furthermore, scoping directions for future research were provided to enhance the homogeneity and comparability of studies investigating the neural responses to CE. The magnitude of CE was 21.1 +/- 18.2% (mean +/- SD; P < 0.0001) in 22 RCTs ( n = 467 subjects) that measured at least 1 neurophysiological variable in the untrained side, including the following: electromyography (EMG; 14 studies); motor evoked potential (MEP; 8 studies); short-interval intracortical inhibition (SICI), recruitment curve, and M wave (6 studies); cortical silent period (cSP; 5 studies); interhemispheric inhibition, intracortical facilitation (ICF), and H reflex (2 studies); and V wave, short-interval ICF, short-latency afferent inhibition, and long-latency afferent inhibition (1 study). Only EMG, MEP, ICF, cSP, and SICI could be included in the meta-analysis (18 studies, n = 387). EMG ( P = 0.26, n = 235) and MEP amplitude ( P = 0.11, n = 145) did not change in the untrained limb after CE. cSP duration ( P = 0.02, n = 114) and SICI ( P = 0.001, n = 95) decreased in the untrained hemisphere according to body region and type and intensity of training. The magnitude of CE did not correlate with changes in these transcranial magnetic stimulation (TMS) measures. The design of this meta analytical study and the lack of correlations prevented the ability to link mechanistically the observed neurophysiological changes to CE. Notwithstanding the limited amount of data available for pooling, the use of TMS to assess the ipsilateral neurophysiological responses to unilateral training still confirms the central neural origin hypothesis of chronic CE induced by strength training. However, how these neural adaptations contribute to CE remains unclear. PMID- 29446712 TI - Measures of sympathetic and parasympathetic autonomic outflow from heartbeat dynamics. AB - Reliable and effective noninvasive measures of sympathetic and parasympathetic peripheral outflow are of crucial importance in cardiovascular physiology. Although many techniques have been proposed to take up this long-lasting challenge, none has proposed a satisfying discrimination of the dynamics of the two separate branches. Spectral analysis of heart rate variability is the most currently used technique for such assessment. Despite its widespread use, it has been demonstrated that the subdivision in the low-frequency (LF) and high frequency (HF) bands does not fully reflect separate influences of the sympathetic and parasympathetic branches, respectively, mainly due to their simultaneous action in the LF. Two novel heartbeat-derived autonomic measures, the sympathetic activity index (SAI) and parasympathetic activity index (PAI), are proposed to separately assess the time-varying autonomic nervous system synergic functions. Their efficacy is validated in landmark autonomic maneuvers generally employed in clinical settings. The novel measures move beyond the classical frequency domain paradigm through identification of a set of coefficients associated with a proper combination of Laguerre base functions. The resulting measures were compared with the traditional LF and HF power. A total of 236 ECG recordings were analyzed for validation, including autonomic outflow changes elicited by procedures of different nature and temporal variation, such as postural changes, lower body negative pressure, and handgrip tests. The proposed SAI-PAI measures consistently outperform traditional frequency-domain indexes in tracking expected instantaneous autonomic variations, both vagal and sympathetic, and may aid clinical decision making, showing reduced intersubject variability and physiologically plausible dynamics. NEW & NOTEWORTHY While it is possible to obtain reliable estimates of parasympathetic activity from the ECG, a satisfying method to disentangle the sympathetic component from HRV has not been proposed yet. To overcome this long-lasting limitation, we propose two novel HRV based indexes, the sympathetic and parasympathetic activity indexes. PMID- 29446713 TI - Mitigation of airways responsiveness by deep inflation of the lung. AB - Stretching activated strips of airway smooth muscle (ASM) significantly affects both active force and stiffness due to a temporary reduction of the proportion of cycling myosin cross bridges that are bound to their actin binding sites. For the same reason, stretch applied to ASM in situ by a deep inflation (DI) of the lungs is one of the most potent means of reversing bronchoconstriction. When the DI is sufficiently large, however, and is applied while bronchoconstriction is in the process of developing, the subsequent depression in airway resistance is more persistent than can be attributed simply to temporary detachment of ASM cross bridges. In the present study, we use a computational model to demonstrate that this DI-induced ablation of airway responsiveness can be explained by a dose dependent reduction in the number of cross bridges available to bind to actin when the ASM in the airway wall is stretched above a critical threshold strain and that this disruption of the contractile apparatus recovers over an order of magnitude longer time scale than that of the simple reattachment of unbound cross bridges. NEW & NOTEWORTHY The mechanisms by which deep inflation of the lung reverse bronchoconstriction and affect subsequent airway responsiveness have important potential implications for asthma, yet remain controversial. This study uses computational modeling to posit a mechanism by which sufficiently vigorous inflations applied during active bronchoconstriction not only transiently reverse bronchoconstriction, but also reduce subsequent airways responsiveness for a period of time. Fitting the model to published data in mice supports this notion. PMID- 29446714 TI - Blunted shear-mediated dilation of the internal but not common carotid artery in response to lower body negative pressure. AB - Shear-mediated dilation in peripheral conduit arteries is blunted with sympathetic nervous system (SNS) activation; however, the effect of SNS activation on shear-mediated dilation in carotid arteries is unknown. We hypothesized that SNS activation reduces shear-mediated dilation in common and internal carotid arteries (CCA and ICA, respectively), and this attenuation is greater in the ICA compared with the CCA. Shear-mediated dilation in the CCA and ICA were measured in nine healthy men (24 +/- 1 yr) with and without SNS activation. Shear-mediated dilation was induced by 3 min of hypercapnia (end tidal partial pressure of carbon dioxide +10 mmHg from individual baseline); SNS activity was increased with lower body negative pressure (LBNP; -20 mmHg). CCA and ICA measurements were made using Doppler ultrasound during hypercapnia with (LBNP) or without (Control) SNS activation. LBNP trials began with 5 min of LBNP with subjects breathing hypercapnic gas during the final 3 min. Shear-mediated dilation was calculated as the percent rise in peak diameter from baseline diameter. Sympathetic activation attenuated shear-mediated dilation in the ICA (Control vs. LBNP, 5.5 +/- 0.7 vs. 1.8 +/- 0.4%, P < 0.01), but not in the CCA (5.1 +/- 1.2 vs. 4.2 +/- 1.0%, P = 0.31). Moreover, absolute reduction in shear mediated dilation via SNS activation was greater in the ICA than the CCA (-3.6 +/ 0.7 vs. -0.9 +/- 0.8%, P = 0.02). Our data indicate that shear-mediated dilation is attenuated during LBNP to a greater extent in the ICA compared with the CCA. These results potentially provide insight into the role of SNS activation on cerebral perfusion, as the ICA is a key supplier of blood to the brain. NEW & NOTEWORTHY We explored the effect of acute sympathetic nervous system (SNS) activation on shear-mediated dilation in the common and internal carotid arteries (CCA and ICA, respectively) in young healthy men. Our data demonstrate that hypercapnia-induced vasodilation of the ICA is attenuated during lower body negative pressure to a greater extent than the CCA. These data may provide novel information related to the role of SNS activation on cerebral perfusion in humans. PMID- 29446715 TI - Update in Women's Heart Disease: Prevention and Screening. AB - The goal in selecting these recent articles was to help identify literature that may change the clinical practice of women's health for internists. Articles were identified by reviewing the high-impact medical and women's health journals, national guidelines, ACP JournalWise, and NEJM Journal Watch. Cardiovascular (CV) disease remains the leading cause of death in women. The emphasis of this review is on identifying opportunities for CV risk reduction to prevent disease and on early identification of women with preexisting atherosclerotic disease to allow for early initiation of medical treatment.

AB - SIRT1 is a nicotinamide adenosine dinucleotide (NAD+)-dependent deacetylase, which removes acetyl groups from many target proteins, such as histone proteins, transcription factors and cofactors. SIRT1-catalyzed deacetylation of these factors modulates the activity of downstream proteins, thus influencing many biological processes. SIRT1 is involved in the regulation of metabolism, inflammation, and tumor growth. The activity of this enzyme is related to the beneficial health effects of calorie restriction, such as lifespan extension and, in particular, the activation of SIRT1 has a positive impact on the cardiovascular system. Therefore, SIRT1 is considered as an attractive drug target and modulation of SIRT1 may represents a new therapeutic strategy against cardiovascular diseases, as small molecules able to activate SIRT1 can be considered as cardioprotective agents. In this review, we summarize both natural or synthetic compounds developed as SIRT1 activators, with a focus on their promising therapeutic applications in cardiovascular pathologies. PMID- 29446718 TI - Current Trends and Future Directions of Fluoroquinolones. AB - Fluoroquinolones represent an interesting synthetic class of antimicrobial agents with broad spectrum and potent activity. Since the discovery of nalidixic acid, the prototype of quinolones, several structural modifications to the quinolone nucleus have been carried out for improvement of potency, spectrum of activity, and to understand their structure activity relationship (SAR). The C-7 substituent was reported to have a major impact on the activity. Accordingly, Substitution at C-7 or its N-4-piperazinyl moiety was found to affect potency, bioavailability, and physicochemical properties. Also, it can increase the affinity towards mammalian topoisomerases that may shift quinolones from antibacterial to anticancer candidates. Moreover, the presence of DNA topoisomerases in both eukaryotic and prokaryotic cells makes them excellent targets for chemotherapeutic intervention in antibacterial and anticancer therapies. Based on this concept, several fluoroquionolones derivatives have been synthesized and biologically evaluated as antibacterial, antituberculosis, antiproliferative, antiviral and antifungal agents. This review is an attempt to focus on the therapeutic prospects of fluoroquinolones with an updated account on their atypical applications such as antitubercular and anticancer activities. PMID- 29446719 TI - DNA Double Strand Breaks Repair Inhibitors: Relevance as Potential New Anticancer Therapeutics. AB - DNA Double-strand breaks are considered one of the most lethal form of DNA damage. Many effective anticancer therapeutic approaches used chemical and physical methods to generate DNA double-strand breaks in the cancer cells. They include: IR and drugs which mimetic its action, topoisomerase poisons, some alkylating agents or drugs which affected DNA replication process. On the other hand, cancer cells are mostly characterized by highly effective systems of DNA damage repair. There are two main DNA repair pathways used to fix double-strand breaks: NHEJ and HRR. Their activity leads to a decreased effect of chemotherapy. Targeting directly or indirectly the DNA double-strand breaks response by inhibitors seems to be an exciting option for anticancer therapy and is a part of novel trends that arise after the clinical success of PARP inhibitors. These trends will provide great opportunities for the development of DNA repair inhibitors as new potential anticancer drugs. The main objective of this article is to address these new promising advances. PMID- 29446720 TI - Electrochemistry of Alzheimer Disease Amyloid Beta Peptides. AB - Alzheimer's disease (AD) is a widespread form of dementia that is estimated to affect 44.4 million people worldwide. AD pathology is closely related to the accumulation of amyloid beta (Abeta) peptides in fibrils and plagues, the small oligomeric intermediate species formed during the Abeta peptides aggregation presenting the highest neurotoxicity. This review discusses the recent advances on the Abeta peptides electrochemical characterization. The Abeta peptides oxidation at a glassy carbon electrode occurs in one or two steps, depending on the amino acid sequence, length and content. The first electron transfer reaction corresponds to the tyrosine Tyr10 amino acid residue oxidation, and the second to all three histidine (His6, His13 and His14) and one methionine (Met35) amino acid residues. The Abeta peptides aggregation and amyloid fibril formation are electrochemically detected via the electroactive amino acids oxidation peak currents decrease that occurs in a time dependent manner. The Abeta peptides redox behaviour is correlated with changes in the adsorption morphology from initially random coiled structures, corresponding to the Abeta peptide monomers in random coil or in alpha-helix conformations, to aggregates, protofibrils and two types of fibrils, corresponding to the Abeta peptides in a beta-sheet configuration, observed by atomic force microscopy. Electrochemical studies of Abeta peptides aggregation, mediated by the interaction with metal ions, particularly zinc, copper and iron, and different methodologies concerning the detection of Abeta peptide biomarkers of AD in biological fluids, using electrochemical biosensors, are also discussed. PMID- 29446721 TI - Fluorescent Imaging of Amyloid-beta Deposits in Brain: An Overview of Probe Development and a Highlight of the Applications for In Vivo Imaging. AB - The beta-amyloid (Abeta) plaques presented within the brain parenchyma have been widely proved to be one of the hallmarks of Alzheimer's disease (AD). According to the amyloid cascade hypothesis, the accumulation of Abeta plaques in the brain is intrinsic and fundamental for disease onset, and much research about the early diagnosis of AD is based on this. A recent development in Abeta detection has focused on the mapping of the molecule events in the brain using an exquisite, noninvasive, and inexpensive optical imaging technique, which has stimulated the rapid development of Abeta-specific fluorescent probes. Among them, nearinfrared (NIR) fluorophores have gained adequate attention due to the weak light attenuation in tissues and avoidance from auto-fluorescence of biological matter. In this review, we showcase the current developments of fluorescent probes that are subject to in vitro or in vivo detection of Abeta plaques in the brain, and give an emphasis on the probes used for in vivo twophoton microscopy and NIR imaging by highlighting their biological and photochemical properties. PMID- 29446722 TI - Herbal compounds with special reference to gastrodin as potential therapeutic agents for microglia mediated neuroinflammation. AB - BACKGROUND: Activated microglia play a pivotal role neurodegenerative diseases by producing a variety of proinflammatory mediators including tumor necrosis factor alpha (TNF-alpha), interleukin-1bea (IL-1beta) and nitric oxide (NO) that are toxic to neurons and oligodendrocytes. METHODS: In view of the above, suppression of microglia mediated neuroinflammation is deemed a therapeutic strategy for neurodegenerative diseases. Several potential Chinese herbal extracts have been reported to exert neuroprotective effects against neurodegenerative diseases targeting specifically at the activated microglia. In this connection, the phenolic glucoside gastrodin, a main constituent of the Chinese herbal medicine Gastrodia rhizoma, produced widely in the local community exhibits potential neuroprotective effects through suppression of neurotoxic proinflammatory mediators. RESULTS: Here, we first review the roles of activated microglia in different brain diseases. The effects of gastrodin on activated microglia are then considered. We have identified gastrodin as a putative therapeutic agent as it has been found to suppress microglial activation thus ameliorating neuroinflammation. More importantly, gastrodin downregulates the expression of renin angiotensin system (RAS) and production of proinflammatory mediators. Remarkably, gastrodin promotes Sirtuin 3 (Sirt3) up-regulation and nicotinamide adenine dinucleotide phosphate oxidase-2 (NOX-2) down-regulation after ischemic hypoxia in activated microglia mediated by AT1 or AT2 receptors which are angiotensin II receptors subtypes, indicating a possible molecular link between RAS and Sirt3 survival genes. CONCLUSION: This review summarizes the beneficial effects of gastrodin acting on activated microglia along with other herbal compounds. Its efficacy in neuroprotection is consistent with some common herbal products in China. PMID- 29446723 TI - Immunomodulatory Effects of Flavonoids in the Prophylaxis and Treatment of Inflammatory Bowel Diseases: A Comprehensive Review. AB - Inflammatory Bowel Diseases (IBD) comprised of two disorders of idiopathic chronic intestinal inflammation that affect about three million people worldwide: Crohn's disease and ulcerative colitis. Nowadays, the first-line of treatment for patients with mild to moderate symptoms of IBD is comprised of corticosteroids, immunosuppressants, antibiotics, and biological agents. Unfortunately, none of these drugs are curative, and their long-term use may cause severe side effects and complications. Almost 40% of IBD patients use alternative therapies to complement the conventional one, and flavonoids are gaining attention for this purpose. The biological properties of flavonoids are well documented and their antioxidant and anti-inflammatory activities have been arousing attention in the scientific community. Flavonoids are the most widely distributed polyphenols in plants and fruits, making part of the human diet. Taking into account that all ingested flavonoids are expected to exert biological actions at the gastrointestinal level, research on the modulatory effect of these compounds in IBD is of paramount importance. This review intends to summarize, in an integrated and comprehensive form, the effect of flavonoids, both in vitro and in vivo, in the different phases of the characteristic IBD inflammatory network. PMID- 29446724 TI - Inhibitors of ER aminopeptidase 1 and 2: from design to clinical application. AB - Endoplasmic Reticulum aminopeptidase 1 and 2 are two homologous enzymes that help generate peptide ligands for presentation by Major Histocompatibility Class I molecules. Their enzymatic activity influences the antigenic peptide repertoire and indirectly controls adaptive immune responses. Accumulating evidence suggests that these two enzymes are tractable targets for the regulation of immune responses with possible applications ranging from cancer immunotherapy to treating inflammatory autoimmune disease. Here, we review the state-of-the-art in the development of inhibitors of ERAP1 and ERAP2 as well as their potential and limitations for clinical applications. PMID- 29446725 TI - Mapping of Protein-Protein Interactions: Web-Based Resources for Revealing Interactomes. AB - BACKGROUND: The significant number of protein-protein interactions (PPIs) discovered by harnessing concomitant advances in the fields of sequencing, crystallography, spectrometry and two-hybrid screening suggests astonishing prospects for remodelling drug discovery. The PPI space which includes up to 650 000 entities is a remarkable reservoir of potential therapeutic targets for every human disease. In order to allow modern drug discovery programs to leverage this we should be able to discern complete PPI maps associated with a specific disorder and corresponding normal physiology. OBJECTIVE: Here, we will review community available computational programs for predicting PPIs and web-based resources for storing experimentally annotated interactions. METHODS: We compared the capacities of prediction tools: iLoops, Struck2Net, HOMCOS, COTH, PrePPI, InterPreTS and PRISM to predict recently discovered protein interactions. RESULTS: We described sequence-based and structure-based PPI prediction tools and addressed their peculiarities. Additionally, since the usefulness of prediction algorithms critically depends on the quality and quantity of the experimental data they are built on, we extensively discussed community resources for protein interactions. We focused on the active and recently updated primary and secondary PPI databases, repositories specialized to the subject or species, as well as databases that include both experimental and predicted PPIs. CONCLUSION: PPI complexes are the basis of important physiological processes and therefore, possible targets for cell-penetrating ligands. Reliable computational PPI predictions can speed up new target discoveries through prioritization of therapeutically relevant protein-protein complexes for experimental studies. PMID- 29446726 TI - Metal-organic framework (MOF)-based nanomaterials for biomedical applications. AB - Metal-organic frameworks (MOFs) are compounds consisting of metal ions or clusters coordinated to organic ligands to form one-, two-, or three-dimensional structures. They are a subclass of coordination polymers (CPs), with the special feature that they are often porous. The organic ligands are sometimes referred to as second building structs. The new porous materials have paid great attention because of the variety of advantages such as tunable components, structural diversity, high loading performance and favorable biodegradability. In this review, we highlighted the recent progress on the drug delivery application of MOFs, especially emphasizing the application of pH-responsive delivery as well as magnetic-guided drug delivery systems (DDSs). Subsequently, the applications of MOFs in magnetic resonance imaging (MRI), optical imaging (OI), X-ray computed tomography (CT) imaging and multimodality imaging will be discussed. Finally, we will provide an overview for the photodynamic therapy and the toxicity feature of MOFs. PMID- 29446727 TI - Natural Terpenoids Against Female Breast Cancer: A 5-year Recent Research. AB - BACKGROUND: The approval of Taxol(r) in 1993 marked the great entrance of terpenoids in the anti-cancer area and this drug is still highly important in the treatment of refractory ovarian, breast and other cancers. Over decades, other prominent natural terpenoids have become indispensable for the modern pharmacotherapy of breast cancer. However, given the rapid evolution of drug resistance, effective treatments for advanced breast cancers requiring cytotoxic chemotherapy represent a major unmet clinical need. Therefore, innovative agents effective in long-term chemotherapy are urgently needed. OBJECTIVE: This review examines recent advances/research about natural terpenoids, and their mechanisms against female breast cancer over the period covering January 1st, 2012 to December 31st, 2016. RESULTS: Carcinogenesis constitutes a multistep process wherein each stage is characterized by distinct phenotypic changes. Numerous chemicals recorded in this review have been shown to significantly inhibit proliferation, migration, apoptosis resistance, tumor angiogenesis or metastasis in different breast cancer cells/tumours in vitro and in vivo. Targeting simultaneously several or all these aspects/steps of cancer progression could be an advantage. In line with this, phytochemicals such as thymoquinone (8), costunolide (46), tanshinone IIA (132), triptolide (136), cucurbitacin B (179), celastrol (226) and lycopene (238) had caught our attention. CONCLUSION: These compounds appear to be promising to overcome breast cancer treatment failure. However, despite the interesting activities, additional preclinical investigations are needed in further breast cancer cell/tumor models in vitro and in vivo. PMID- 29446728 TI - Recent advances in the use of metallic nanoparticles with antitumoral action. AB - The term cancer represents a set of more than 100 diseases that are caused due to an uncontrolled growth of cells; and their subsequent spread to the other tissues and organs of the body by a phenomenon, called 'metastasis'. According to the estimates provided by the World Health Organization (WHO), cancer is expected to account for about 10 million deaths per year by 2020, and 21 million cancer cases, which may lead to 13 million deaths by 2030, making cancer as the cause of highest mortality in contrast to other diseases. The search for potential therapeutics against cancer, which can reduce the side-effects that occur due to the difficulty of recognition between cancerous and normal cells, has ever been increased. In this view, nanotechnology, especially metallic nanoparticles (MNPs), comes to aid in the development of novel therapeutic agents, which may be synthesized or modified with the most diverse functional chemical groups; this property makes the metallic nanoparticles suitable for conjugation with already known drugs or prospective drug candidates. The biocompatibility, relatively simple synthesis, size flexibility and easy chemical modification of its surface, all make the metallic nanoparticles highly advantageous for opportune diagnosis and therapy of cancer. The present article analyzes and reports the anti-tumor activities of 78 papers of various metallic nanoparticles, particularly the ones containing copper, gold, iron, silver, and titanium in their composition. PMID- 29446729 TI - Recent Progress in the Development of Fluorometric Chemosensors to Detect Enzymatic Activity. AB - Enzymes are a class of macromolecules that function as highly efficient and specific biological catalysts requiring only mild reaction conditions. Enzymes are essential to maintaining life activities, including promoting metabolism and homeostasis, and participating in a variety of physiological functions. Accordingly, enzymatic levels and activity are closely related to the health of the organism, where enzymatic dysfunctions often lead to corresponding diseases in the host. Because of this, diagnosis of certain diseases is based on the levels and activity of certain enzymes. Therefore, rapid real-time and accurate detection of enzymes in situ is important for diagnosis, monitoring, clinical treatment, and pathological studies of disease. Fluorescent probes have unique advantages in terms of detecting enzymes, including being simple to use in highly sensitive and selective real-time rapid in-situ non-invasive and highly spatial resolution visual imaging. However, fluorescent probes are most commonly used to detect oxidoreductases, transferases, and hydrolases due to the processes and types of enzyme reactions. This paper summarizes the application of fluorescent probes to detect these three types of enzymes over the past five years. In addition, we introduce the mechanisms underlying detection of these enzymes by their corresponding probes. PMID- 29446730 TI - Salvaging the ischemic heart: Gi-coupled receptors in mast cells activate a PKCepsilon/ALDH2 pathway providing anti-RAS cardioprotection. AB - BACKGROUND: Excessive norepinephrine (NE) release in the ischemic heart elicits severe and often lethal arrhythmias. Resident cardiac mast cells synthesize and store active renin, which is released upon degranulation, causing the activation of a local cardiac renin-angiotensin system (RAS) responsible for NE release and consequent arrhythmias. Toxic aldehydes, known to be formed by lipid peroxidation in ischemia/reperfusion (I/R), have been shown to degranulate mast cells and activate a local RAS. OBJECTIVE: To provide an up-to-date description of the roles of ischemic preconditioning (IPC) and Gi-coupled receptors in anti-RAS cardioprotection. METHODS: Ex-vivo I/R models in cavian and murine hearts, and human and murine mast cell lines in vitro. RESULTS: IPC not only drastically reduces the injury subsequent to a prolonged ischemic event, but also decreases mast cell renin release, thus affording anti-RAS cardioprotection. Similarly, activation of Gi-coupled receptors, such as histamine-H4, adenosine-A3 and sphingosine-1-phosphate-S1P1 receptors, all expressed at the mast cell surface, mimic the cardioprotective anti-RAS effects of IPC. The mechanism of this action depends on the sequential activation of a specific isoform of protein kinase C, PKCepsilon, and mitochondrial aldehyde dehydrogenase-type 2 (ALDH2). Increased ALDH2 enzymatic activity exerts a pivotal role in the sequential inhibition of aldehyde-induced mast-cell renin release, prevention of RAS activation, reduction of NE release and alleviation of reperfusion arrhythmias. CONCLUSION: These recently discovered protective pathways indicate that activation of mast-cell Gi coupled receptors and subsequent ALDH2 phosphorylation/activation represent a novel therapeutic target for the alleviation of RAS-induced cardiac dysfunctions, including ischemic heart disease and congestive heart failure. PMID- 29446732 TI - Biomedical Potentialities of Taraxacum officinale-based Nanoparticles Biosynthesized Using Methanolic Leaf Extract. AB - BACKGROUND: In the present study, the potential of methanolic leaf extract of Taraxacum officinale plant as a function of bio-inspired green synthesis for the fabrication of silver nanoparticles (AgNPs) has been explored. METHODS: The bio reduction of aqueous silver nitrate (AgNO3) solution was confirmed by visually detecting the color change from pale yellow to blackish-brown. Maximum absorbance was observed at 420 nm due to the presence of characteristic surface Plasmon resonance of nano silver by UV-visible spectroscopy. The role of various functional groups in the bio-reduction of silver and chemical transformation was verified by Fourier transform infrared spectroscopy (FTIR). Scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX) predict the shape (rocky, flack type, ellipsoidal, etc.), size (68 nm) and elemental composition (Ag as a major constituent) of the biosynthesized AgNPs, respectively. RESULTS: Transmission electron microscopy (TEM) analysis further corroborated the morphology of the AgNPs. Color mapping and atomic force microscopy (AFM) confirmed the nano-sized topography. The dynamic light scattering (DLS) showed the charge, stability, and size of the AgNPs. The generated AgNPs presented potential antibacterial activities against Gram-positive and Gram-negative bacterial strains including Staphylococcus aureus, Escherichia coli, and Haemophilus influenzae. The biosynthesized AgNPs also showed antiproliferative activity against MCF-7 breast cancer cell line in a dosedependent manner. CONCLUSION: In conclusion, results clearly indicate that biosynthesized AgNPs could be used as effective nano drug for treating infectious diseases caused by multidrug resistant bacterial strains in the near future. PMID- 29446733 TI - Current Understanding of Inflammatory Responses in Acute Kidney Injury. AB - Acute kidney injury has been a tough complex with increased mortality and morbidity. Inflammatory responses, including innate and adaptive immune responses, involve in the initiation and development of acute kidney injury, especially under the ischemic circumstances. Tubular cells and distinct immune cell subgroups play a critical role in the pathogenesis of inflammation. Current gene therapies show their benefits in renal repair. Here, we reviewed the renal inflammatory infiltration, inflammatory mediators, oxidative stress and potential signaling pathways, which give rise to the kidney diseases, in the mechanism of acute kidney injury. Recent studies showed diverse insights in understanding the pathophysiological process of inflammation related renal injury and provided novel clinical targets for ameliorating acute kidney injury by balancing the facilitation of repairing and prevention of impairing. Interestingly, antisense oligonucleotides of target sequence, local electransfering on solid organ and adenovirus-mediated certain gene overexpression have been promising strategies in alleviating acute kidney injury. PMID- 29446735 TI - Epigenetic Regulation of Regulatory T Cells in Kidney Disease and Transplantation. AB - Regulatory T (Treg) cells are a kind of immunosuppression cells, which have been used to treat autoimmune diseases and induce allograft tolerance in clinical trials. While Treg cells based therapy is a promising treatment for kidney diseases and an emerging concept for tolerance induction in renal transplantation, a better understanding of the functions and biology of Treg cells is needed to be able to optimally exploit them. Epigenetics regulation, which refers to potentially heritable alterations in gene expression without underlying changes of the nucleotide sequence, plays an important role in Treg cells induction and maintenance. The expression of Foxp3, the key factor of Treg cells, is regulated by DNA methylation, histone modification and post transcriptionally modification. Herein, we review the current understanding of Treg cells in kidney diseases and transplantation, and discuss the epigenetic regulation of Treg cells. PMID- 29446731 TI - Vitamin D Receptor: A Novel Therapeutic Target for Kidney Diseases. AB - BACKGROUND: Kidney disease is a serious problem that adversely affects human health, but critical knowledge is lacking on how to effectively treat established chronic kidney disease. Mounting evidence from animal and clinical studies has suggested that Vitamin D Receptor (VDR) activation has beneficial effects on various renal diseases. METHODS: A structured search of published research literature regarding VDR structure and function, VDR in various renal diseases (e.g., IgA nephropathy, idiopathic nephrotic syndrome, renal cell carcinoma, diabetic nephropathy, lupus nephritis) and therapies targeting VDR was performed for several databases. RESULT: Included in this study are the results from 177 published research articles. Evidence from these papers indicates that VDR activation is involved in the protection against renal injury in kidney diseases by a variety of mechanisms, including suppression of RAS activation, anti inflammation, inhibiting renal fibrogenesis, restoring mitochondrial function, suppression of autoimmunity and renal cell apoptosis. CONCLUSION: VDR offers an attractive druggable target for renal diseases. Increasing our understanding of VDR in the kidney is a fertile area of research and may provide effective weapons in the fight against kidney diseases. PMID- 29446736 TI - Gene Therapy in Kidney Transplantation: Evidence of Efficacy and Future Directions. AB - Allograft loss remains a severe clinical problem after kidney transplantation. The molecular mechanism of graft loss is a complex process involving T and/or B cell activation, inflammation responses, autophagy and apoptosis. Since these pathways are involved in immune responses in kidney transplant rejection, application of genetic interference to inhibit specific pathways could present an effective targeted gene therapy method. Recent studies have successfully attempted to use gene therapy to target the key molecules involved in immune responses during transplantation. This strategy has the potential to silence target genes associated with a variety of diseases, including those that trigger allograft loss following organ transplantation. In this review, we have discussed evidence of the clinical applicability of gene therapy in kidney transplantation based on known associations between kidney diseases and genes participating in the underlying mechanisms. The molecules contributing to immune responses and inflammatory injury are further highlighted as potential targets in future clinical therapy for renal transplantation. PMID- 29446734 TI - CX3CL1/CX3CR1 Axis, as the Therapeutic Potential in Renal Diseases: Friend or Foe? AB - The fractalkine receptor chemokine (C-X3-C motif) receptor 1 (CX3CR1) and its highly selective ligand CX3CL1 mediate chemotaxis and adhesion of immune cells, which are involved in the pathogenesis and progression of numerous inflammatory disorders and malignancies. The CX3CL1/CX3CR1 axis has recently drawn attention as a potential therapeutic target because it is involved in the ontogeny, homeostatic migration, or colonization of renal phagocytes. We performed a Medline/PubMed search to detect recently published studies that explored the relationship between the CX3CL1/CX3CR1 axis and renal diseases and disorders, including diabetic nephropathy, renal allograft rejection, infectious renal diseases, IgA nephropathy, fibrotic kidney disease, lupus nephritis and glomerulonephritis, acute kidney injury and renal carcinoma. Most studies demonstrated its role in promoting renal pathopoiesis; however, several recent studies showed that the CX3CL1/CX3CR1 axis could also reduce renal pathopoiesis. Thus, the CX3CL1/CX3CR1 axis is now considered to be a double-edged sword that could provide novel perspectives into the pathogenesis and treatment of renal diseases and disorders. PMID- 29446737 TI - Gene-modified Mesenchymal Stem Cell-based Therapy in Renal Ischemia- Reperfusion Injury. AB - Acute Kidney Injury (AKI) is a common syndrome in the clinic and has become a worldwide public health problem. Renal Ischemia-Reperfusion Injury (IRI) is the most common cause of AKI. So far, effective treatment is still lacking for renal IRI, resulting in a high mortality rate of AKI. Mesenchymal Stem Cells (MSCs), considered as a promising candidate for tissue repair and regenerative medicine have aroused an increasing concern in recent years for the capacity of self renewal and multi-lineage differentiation. MSC-based therapy has drawn wide attention for its therapeutic potential in renal IRI. The administrated MSCs can alleviate the renal IRI and improve the renal function for its anti-inflammatory, immunomodulation properties. MSCs preferentially migrate into injured sites to play the role of tissue repair. Furthermore, MSCs can modify the microenvironment to promote the recovery of damaged renal tubular cells via paracrine factors. However, the poor kidney-directional homing and poor survival under ischemia environment have limited their beneficial effects. Genetic modification is an effective approach to increase the therapeutic action of MSCs. MSCs are modified with exogenous genes to enhance their innate properties. Here we review the current knowledge of gene-modified MSCs, their biological characteristics and applications in renal IRI. PMID- 29446738 TI - How Do Dendritic Cells Play the Role in Ischemia/Reperfusion Triggered Kidney Allograft Rejection. AB - In deceased donors, Ischemia/Reperfusion Injury (IRI) is an important cause of allograft dysfunction. Prolonged cold and warm ischemia time leads to a high risk of early post-transplant complications, including acute and chronic rejection. Ischemia not only up-regulates inflammatory cytokines and chemokines, but also enhances the expression of MHC-class II and adhesion molecules on epithelial and dendritic cells. Moreover, the Danger Associated Molecular Patterns (DAMPs) released from stressed or dying cells, not only cause or amplify tissue inflammation and trigger tissue repair in response to IRI, but also act as adjuvants that enhance DC maturation and potentiate the adaptive immune response. In this review, we will also discuss about whether donor or recipient DCs are more important in the process of ischemia enhanced acute rejection. PMID- 29446739 TI - Role of Complement Properdin in Renal Ischemia-Reperfusion Injury. AB - Renal Ischemia-Reperfusion Injury (IRI) is one of the main causes of Acute Kidney Injury (AKI), and may lead to chronic kidney disease. The high mortality rate of AKI has not changed in the last 5 decades due to non-recognition, nephrotoxin exposure, delayed diagnosis and lack of specific intervention. Complement activation plays important roles in IRI-induced AKI because of its association with immunity, inflammation, cell death and tissue repair. Nevertheless, the role of complement properdin, the sole positive regulator of the alternative pathway, in IRI-induced AKI has not been well defined. This review evaluates the dynamic changes and underlying mechanisms of complement activation with a focus on properdin in both in vitro and in vivo models challenged by hypoxia/ reoxygenation and renal IRI. The multiple actions of properdin associated with HMGB1 and caspase-3, apoptosis and inflammation mediators, are discussed in the context of immunity, injury and repair at both the early and later stages of AKI. The complement activation-independent role of properdin and the effect of modulating properdin with or without genotype alteration are also addressed. Taking together, these might provide new mechanistic insights that potentially benefit timely diagnosis and specific intervention of IRI-induced AKI. PMID- 29446740 TI - Role of Immune Cells in Diabetic Kidney Disease. AB - Diabetic Kidney Disease (DKD) is one of the major complications of Diabetes Mellitus (DM) and is currently the most common cause of End-Stage Renal Disease (ESRD) worldwide. Traditionally, DKD is considered a disease which has nothing to do with the immune system, and the pathogenesis is mainly characterized to be metabolic disturbance. Recent growing evidence indicates immunologic and inflammatory mechanisms in the development and progression of DKD. This overview of macrophages, dendritic cells, T lymphocytes, B lymphocytes, neutrophils and mast cells is closely involved in the pathologic process of DKD, with more emphasis on the leucocyte accumulation and related molecular mechanisms. Moreover, the potential contributions of these immune cells to renal injury will also be discussed. Specifically, these findings help to identify new potential therapeutic targets of DKD. Future preclinical and clinical studies might translate these exciting findings into clinical applications. PMID- 29446741 TI - What's new in Gene Therapy of Hemophilia. AB - BACKGROUND: Several methods have been investigated to effectively and safely transmit genes that stimulate cells to release therapeutic factor VIII (FVIII) and factor IX (FIX) into the circulation of people with hemophilia (PWH). OBJECTIVE: To review the role of gene therapy (GT) in PWH. METHODS: A Cochrane Library and PubMed (MEDLINE) search related to the role of GT in hemophilia was analyzed. RESULTS: The most promising vectors for hemophilia GT are adeno associated virus (AAV) and lentivirus. Several gene methods are available to lessen risks related to random vector integration and insertional mutagenesis, based on designer nucleases or CRISPR/Cas9 (clustered regularly interspaced short palindromic repeats/CRISPR associated system). However, off-target issues need to be more meticulously and widely evaluated. Some clinical studies on hemophilia B based on AAV have obtained transitory or subtherapeutic levels of FIX expression. Another problem is possible transitory liver toxicity. Therefore, to reduce unintentional immune responses, transitory immunosuppression must be used, particularly when administering high-vector doses. Codon-optimized FVIII or FIX transgenes are able to promote clotting factor expression levels. The inclusion of a hyper-active gain-of-function R338L mutation in the FIX gene (FIX-R338L [FIX Padua]) makes the procedure more effective. CONCLUSION: Achieving a safe and efficient remedy for hemophilia A and B by means of GT vector engineering needs further improvement. No randomized or quasi-randomized clinical trials of GT for hemophilia have been found. Given it is in its incipient period, there is need for well-designed clinical trials to evaluate the long-term practicability, efficacy and risks of GT for PWH. PMID- 29446742 TI - Development of an In-vitro Drug Delivery Efficiency Test for a Pulmonary Toxicokinetic Pig Study. AB - BACKGROUND: Since their appearance on the drugs of abuse market, synthetic cannabinoids (SCs) are gaining increasing toxicological relevance. They are consumed without knowledge of their toxicokinetic (TK) and toxicodynamic properties and human studies are not allowed due to ethical reasons. A controlled animal TK study following nebulization of 4-ethylnaphthalene-1-yl-(1-pentylindole 3-yl)methanone (JWH-210), 2-(4-methoxyphenyl)-1-(1-pentyl-indole-3-yl)methanone (RCS-4) as well as Delta9-tetrahydrocannabinol (THC) to pigs should be helpful for better interpretation of analytical results in cases of misuse or poisoning. As a prerequisite, an in-vitro test system mimicking a ventilated pig had to be developed to determine the quantity and reproducibility of which drug dose is delivered to the pig lung. METHODS: JWH-210, RCS-4, and THC (1 mg in 2 mL ethanol each) were nebulized during ventilation using an ultrasonic nebulizer. The drug aerosol was delivered via the inspiratory limb and the endotracheal tube passing through a glass fiber filter (n = 6). The drugs were extracted from the filters using ethanol and ultrasonication. After several dilution steps and adding an internal standard solution, the extracts were analyzed by LC-MS/MS. RESULTS: Extraction of the nebulized drugs revealed delivery efficiencies of 78.8 +/- 5.0% for JWH-210, 70.5 +/- 6.9% for RCS-4, and 70.8 +/- 7.9% for THC. The loss of about 20-30% of the administered dose might be attributable to retention in the nebulizer device or adhesion of the aerosol particles to the tube wall. CONCLUSION: Nevertheless, regarding delivery efficiencies, the minor standard deviations indicate an acceptable reproducibility, suggesting that this administration system is suitable for application in TK studies. PMID- 29446743 TI - Recent Advances in Antioxidant Cosmeceutical Topical Delivery. AB - Antioxidants are among the most important cosmeceuticals, with proven ability of inhibiting cellular damage. The topical skin administration of antioxidants is essential for minimizing skin aging and achieving better skin protection against harmful free radicals. However, their unfavorable physiochemical properties such as chemical instability, excessive hydrophilicity or lipophilicity and others could be a great obstacle against their skin promising effects as well as their delivery to deeper skin layers. These problems could all be remedied through the use of delivery carriers. The present review discusses the various delivery carriers which were proven successful in improving the beneficial effects of antioxidants against skin aging, namely different vesicular systems, lipidic systems, polymeric systems and carbon nanotubes, and their applications in topical antioxidant delivery. PMID- 29446744 TI - Delivery of Peptidic Gonadotropin Releasing Hormone Antagonists. AB - GnRH antagonists have several clinical applications in prostate cancer, regulation of ovulation induction in females, breast cancer, male contraception and others. Antagonists differ from natural GnRH decapeptide in having five or more amino acid substitutions, whereas most of the antagonists are available as subcutaneous (SC) formula for injection some are formulated as a depot formulation for sustained release (e.g., Cetrorelix, Degarelix). Systemic delivery of cetrorelix acetate by intratracheal route can be achieved using dry powder for inhalation of the adhesive mixture when the powder deposition reaches stage four. The oral route for systemic delivery of peptide without its degradation can be achieved using gastrointestinal permeation enhancement technology GIPET(r) provided by acyline. PMID- 29446746 TI - Mechanisms involved in glycemic control promoted by exercise in diabetics. AB - INTRODUCTION: Diabetes mellitus is a metabolic disease characterized by high glycemic levels for long periods. This disease has a high prevalence in the world population, being currently observed an increase in its incidence. This fact is mainly due to the sedentary lifestyle and hypercaloric diets. Non-pharmacological interventions for glycemic control include exercise, which promotes changes in skeletal muscle and adipocytes. Thus, increased glucose uptake by skeletal muscle and decreased insulin resistance through modulating adipocytes are the main factors that improve glycemic control against diabetes. Conclusio: it was sought to elucidate mechanisms involved in the improvement of glycemic control in diabetics in front of the exercise.

PMID- 29446747 TI - CRISPR/Cas9 Genome Editing: A Promising Tool for Therapeutic Applications of Induced Pluripotent Stem Cells. AB - BACKGROUND: Induced pluripotent stem cells hold tremendous potential for biological and therapeutic applications. The development of efficient technologies for targeted genome alteration of stem cells in disease models is a prerequisite for utilizing stem cells to their full potential. The revolutionary technology for genome editing known as the clustered regularly interspaced short palindromic repeat (CRISPR)-associated protein 9 (Cas9) system is recently recognized as a powerful tool for editing DNA at specific loci. OBJECTIVE: The ease of use of the CRISPR-Cas9 technology will allow us to improve our understanding of genomic variation in disease processes via cellular and animal models. More recently, this system was modified to repress (CRISPR interference, CRISPRi) or activate (CRISPR activation, CRISPRa) gene expression without alterations in the DNA, which amplified the scope of applications of CRISPR systems for stem cell biology. RESULTS AND CONCLUSION: Here, we highlight latest advances of CRISPR-associated applications in human pluripotent stem cells. The challenges and future prospects of CRISPR-based systems for human research are also discussed. PMID- 29446749 TI - The seroprevalence of cystic echinococcosis in a rural normal population, southwestern Iran. AB - INTRODUCTION: Cystic echinococcosis is a neglected zoonotic disease with worldwide distribution, which occurs mainly in pastoral regions. Echinococcus granulosus sensu stricto, is the main agent of human infection. Although Iran is an endemic area for CE in the Middle East, lack of data regarding the disease among rural inhabitants of Khuzestan province in recent years, persuaded us to perform the current study. METHODOLOGY: This cross-sectional study was conducted in 2016 using simple random sampling method in 15 villages of Shushtar county, southwestern Iran. Three hundred and fourteen of rural inhabitants were examined using AgB- ELISA test for CE. RESULTS: From the 314 patients included in the study, females and males were 244 (77.7%) and 70 (22.3%), respectively. Of these, 227 (72.3%) were in close contact with dogs, which 173 (70.9%) of them were females and 54 (29.1%) were males. ELISA detected three (1%) seropositive cases among investigated population. All three positive cases were females and in close contact with dogs. Furthermore, the positive cases in the age range of 21-50. None of the 70 examined males were positive. CONCLUSIONS: This study is the first report of CE in rural areas of Shushtar, Southwest Iran, which indicated seroprevalence of CE among rural areas with high prevalence rate of infection among females. It seems that the rural population of the region are at the risk of exposure to E. granulosus eggs. Therefore, more studies are required to evaluate the human CE in all parts of the province using serological and ultrasound methods. PMID- 29446748 TI - Anti-Oxidants as Chemopreventive Agents in Prostate Cancer: A Gap Between Preclinical and Clinical Studies. AB - BACKGROUND: Tumor cells may be expressed as a result of oxidative stress. The extent of oxidative stress correlates with the aggressive and metastatic potency of cancer. OBJECTIVE: One simple way to control prostate cancer is through chemoprevention which refers to the administration of natural or synthetic agents to block, reverse, or delay the process of carcinogenesis. The most chemopreventive agents are antioxidants in nature. METHODS: In this review, we summarized the effects of dietary antioxidants with a focus on their molecular mechanisms and possible roles in the treatment of prostate cancer cells. We also reported the recent outcomes of laboratory and/or clinical trials of antioxidants in prostate cancer patients. RESULTS: Numerous pre-clinical studies showed that antioxidants protect DNA against being damaged by Reactive Oxygen Species (ROS), thereby genetic mutations causing cancer are likely to be prevented. However, the clinical trial results showed that antioxidants have yielded mixed outcomes or benefitted only a subgroup of the population. CONCLUSION: A greater understanding of the molecular events associated with antioxidants will enhance the development of treatment and could result in better strategies for the chemoprevention of prostate cancer. Recent patents also suggest that anti-oxidant compounds can be effective for the prevention and the treatment of prostate cancer. PMID- 29446750 TI - Copaiba Oil Decreases Oxidative Stress and Inflammation But not Colon Damage in Rats with TNBS-Induced Colitis. AB - BACKGROUND: TNBS-induced colitis is an experimental immunopathology in rats that shares many features with human inflammatory bowel diseases. Copaiba oleoresin is extracted from plants of the genus Copaifera and is shown to reduce inflammation. OBJECTIVE: The aim of this study was to investigate the action of copaiba oil (C. reticulata Ducke) on inflammation and oxidative status in the distal colon of colitic rats. METHODS: Acute and subchronic colitis were induced in Wistar rats by an intracolonic enema with 2,4,6-trinitrobenzenesulfonic acid (TNBS). The colonic morphology was assessed by histological analysis and the oxidative stress parameters were measured in the intestinal homogenate. The liver damage markers were measured in the plasma. Control and colitic rats were orally treated either with one single dose (acute colitis) of copaiba oil (1.15 g Kg-1) or once a day during seven days (subchronic colitis). RESULTS: The intestinal morphology was severely modified by acute and subchronic colitis, as indicated by the intramural infiltration of polymorphonuclear cells and the increased thickness of all colon layers. The levels of TBARS, protein carbonyl groups and reactive oxygen species (ROS) were increased in the intestine of colitic rats. Copaiba oil did not attenuate the inflammatory damage in acute and subchronic colitis, but it decreased the activity of myeloperoxidase, leukocyte infiltration and oxidative stress in the colon. The level of plasma bilirubin and the activity of alkaline phosphatase were both increased in treated healthy and colitic rats. CONCLUSION: Copaiba oil decreased oxidative stress and inflammation but did not prevent intestinal damage in the colon of colitic rats. The alterations of plasma markers of hepatic damage caused by the oil seem to be associated to its harmful action on the liver. PMID- 29446751 TI - Molecular mechanism to target the endosomal Mon1-Ccz1 GEF complex to the pre autophagosomal structure. AB - During autophagy, a newly formed double membrane surrounds its cargo to generate the so-called autophagosome, which then fuses with a lysosome after closure. Previous work implicated that endosomal Rab7/Ypt7 associates to autophagosomes prior to their fusion with lysosomes. Here, we unravel how the Mon1-Ccz1 guanosine exchange factor (GEF) acting upstream of Ypt7 is specifically recruited to the pre-autophagosomal structure under starvation conditions. We find that Mon1-Ccz1 directly binds to Atg8, the yeast homolog of the members of the mammalian LC3 protein family. This requires at least one LIR motif in the Ccz1 C terminus, which is essential for autophagy but not for endosomal transport. In agreement, only wild-type, but not LIR-mutated Mon1-Ccz1 promotes Atg8-dependent activation of Ypt7. Our data reveal how GEF targeting can specify the fate of a newly formed organelle and provide new insights into the regulation of autophagosome-lysosome fusion.

PMID- 29446752 TI - Allosteric mechanism of the V. vulnificus adenine riboswitch resolved by four dimensional chemical mapping. AB - The structural interconversions that mediate the gene regulatory functions of RNA molecules may be different from classic models of allostery, but the relevant structural correlations have remained elusive in even intensively studied systems. Here, we present a four-dimensional expansion of chemical mapping called lock-mutate-map-rescue (LM2R), which integrates multiple layers of mutation with nucleotide-resolution chemical mapping. This technique resolves the core mechanism of the adenine-responsive V. vulnificus add riboswitch, a paradigmatic system for which both Monod-Wyman-Changeux (MWC) conformational selection models and non-MWC alternatives have been proposed. To discriminate amongst these models, we locked each functionally important helix through designed mutations and assessed formation or depletion of other helices via compensatory rescue evaluated by chemical mapping. These LM2R measurements give strong support to the pre-existing correlations predicted by MWC models, disfavor alternative models, and suggest additional structural heterogeneities that may be general across ligand-free riboswitches. PMID- 29446754 TI - Highly polarization sensitive photodetectors based on quasi-1D titanium trisulfide (TiS3). AB - Photodetectors with high polarization sensitivity are in great demand in advanced optical communication. Here, we demonstrate that photodetectors based on titanium trisulfide (TiS3) are extremely sensitive to polarized light (from visible to the infrared), due to its reduced in-plane structural symmetry. By density functional theory calculation, TiS3 has a direct bandgap of 1.13 eV. The highest photoresponsivity reaches 2500 A W-1. What is more, in-plane optical selection caused by strong anisotropy leads to the photoresponsivity ratio for different directions of polarization that can reach 4:1. The angle-dependent photocurrents of TiS3 clearly display strong linear dichroism. Moreover, the Raman peak at 370 cm-1 is also very sensitive to the polarization direction. The theoretical optical absorption of TiS3 is calculated by using the HSE06 hybrid functional method, in qualitative agreement with the observed experimental photoresponsivity. PMID- 29446755 TI - Classification methods to detect sleep apnea in adults based on respiratory and oximetry signals: a systematic review. AB - OBJECTIVE: Sleep apnea (SA), a common sleep disorder, can significantly decrease the quality of life, and is closely associated with major health risks such as cardiovascular disease, sudden death, depression, and hypertension. The normal diagnostic process of SA using polysomnography is costly and time consuming. In addition, the accuracy of different classification methods to detect SA varies with the use of different physiological signals. If an effective, reliable, and accurate classification method is developed, then the diagnosis of SA and its associated treatment will be time-efficient and economical. This study aims to systematically review the literature and present an overview of classification methods to detect SA using respiratory and oximetry signals and address the automated detection approach. APPROACH: Sixty-two included studies revealed the application of single and multiple signals (respiratory and oximetry) for the diagnosis of SA. MAIN RESULTS: Both airflow and oxygen saturation signals alone were effective in detecting SA in the case of binary decision-making, whereas multiple signals were good for multi-class detection. In addition, some machine learning methods were superior to the other classification methods for SA detection using respiratory and oximetry signals. SIGNIFICANCE: To deal with the respiratory and oximetry signals, a good choice of classification method as well as the consideration of associated factors would result in high accuracy in the detection of SA. An accurate classification method should provide a high detection rate with an automated (independent of human action) analysis of respiratory and oximetry signals. Future high-quality automated studies using large samples of data from multiple patient groups or record batches are recommended. PMID- 29446756 TI - Plasmon-enhanced scattering and charge transfer in few-layer graphene interacting with buried printed 2D-pattern of silver nanoparticles. AB - Hybrid structures combing silver nanoparticles and few-layer graphene have been synthetized by combining low-energy ion beam synthesis and stencil techniques. A single plane of metallic nanoparticles plays the role of an embedded plasmonic enhancer located in dedicated areas at a controlled nanometer distance from deposited graphene layers. Optical imaging, reflectance and Raman scattering mapping are used to measure the enhancement of electronic and vibrational properties of these layers. In particular electronic Raman scattering is shown as notably efficient to analyze the optical transfer of charge carriers between the systems and the presence of intrinsic and extrinsic defects. PMID- 29446757 TI - 3D bioprinting mesenchymal stem cell-laden construct with core-shell nanospheres for cartilage tissue engineering. AB - Cartilage tissue is prone to degradation and has little capacity for self-healing due to its avascularity. Tissue engineering, which provides artificial scaffolds to repair injured tissues, is a novel and promising strategy for cartilage repair. 3D bioprinting offers even greater potential for repairing degenerative tissue by simultaneously integrating living cells, biomaterials, and biological cues to provide a customized scaffold. With regard to cell selection, mesenchymal stem cells (MSCs) hold great capacity for differentiating into a variety of cell types, including chondrocytes, and could therefore be utilized as a cartilage cell source in 3D bioprinting. In the present study, we utilize a tabletop stereolithography-based 3D bioprinter for a novel cell-laden cartilage tissue construct fabrication. Printable resin is composed of 10% gelatin methacrylate (GelMA) base, various concentrations of polyethylene glycol diacrylate (PEGDA), biocompatible photoinitiator, and transforming growth factor beta 1 (TGF-beta1) embedded nanospheres fabricated via a core-shell electrospraying technique. We find that the addition of PEGDA into GelMA hydrogel greatly improves the printing resolution. Compressive testing shows that modulus of the bioprinted scaffolds proportionally increases with the concentrations of PEGDA, while swelling ratio decreases with the increase of PEGDA concentration. Confocal microscopy images illustrate that the cells and nanospheres are evenly distributed throughout the entire bioprinted construct. Cells grown on 5%/10% (PEGDA/GelMA) hydrogel present the highest cell viability and proliferation rate. The TGF-beta1 embedded in nanospheres can keep a sustained release up to 21 d and improve chondrogenic differentiation of encapsulated MSCs. The cell-laden bioprinted cartilage constructs with TGF-beta1-containing nanospheres is a promising strategy for cartilage regeneration. PMID- 29446758 TI - Localized thin-section CT with radiomics feature extraction and machine learning to classify early-detected pulmonary nodules from lung cancer screening. AB - Lung cancer screening aims to detect small pulmonary nodules and decrease the mortality rate of those affected. However, studies from large-scale clinical trials of lung cancer screening have shown that the false-positive rate is high and positive predictive value is low. To address these problems, a technical approach is greatly needed for accurate malignancy differentiation among these early-detected nodules. We studied the clinical feasibility of an additional protocol of localized thin-section CT for further assessment on recalled patients from lung cancer screening tests. Our approach of localized thin-section CT was integrated with radiomics features extraction and machine learning classification which was supervised by pathological diagnosis. Localized thin-section CT images of 122 nodules were retrospectively reviewed and 374 radiomics features were extracted. In this study, 48 nodules were benign and 74 malignant. There were nine patients with multiple nodules and four with synchronous multiple malignant nodules. Different machine learning classifiers with a stratified ten-fold cross validation were used and repeated 100 times to evaluate classification accuracy. Of the image features extracted from the thin-section CT images, 238 (64%) were useful in differentiating between benign and malignant nodules. These useful features include CT density (p = 0.002 518), sigma (p = 0.002 781), uniformity (p = 0.032 41), and entropy (p = 0.006 685). The highest classification accuracy was 79% by the logistic classifier. The performance metrics of this logistic classification model was 0.80 for the positive predictive value, 0.36 for the false-positive rate, and 0.80 for the area under the receiver operating characteristic curve. Our approach of direct risk classification supervised by the pathological diagnosis with localized thin section CT and radiomics feature extraction may support clinical physicians in determining truly malignant nodules and therefore reduce problems in lung cancer screening. PMID- 29446759 TI - Photoelastic colloidal gel for a high-sensitivity strain sensor. AB - Nanoparticles, having the ability to self-assemble into an ordered structure in their suspensions, analogous to liquid crystals, have attracted extensive attention. Herein, we report a new type of colloidal gel with an ordered crystal structure assembled from 1D and 2D nanoparticles. The material has high elasticity and, more interestingly, it shows significant photoelasticity. Its refractive index can be tuned under external stress and exhibits an ultra-wide dynamic range (Deltan) of the order of 10-2. Due to the large Deltan, the material shows an extremely high strain sensibility of 720 nm/epsilon, an order of magnitude higher than the reported ones. PMID- 29446760 TI - Quenching-free fluorescence signal from plastic-fibres in proton dosimetry: understanding the influence of Cerenkov radiation. AB - The origin of photons emitted in optical fibres under proton irradiation has been attributed to either entirely Cerenkov radiation or light consisting of fluorescence with a substantial amount of Cerenkov radiation. The source of the light emission is assessed in order to understand why the signal from optical fibres irradiated with protons is reportedly quenching-free. The present study uses the directional emittance of Cerenkov photons in 12 MeV and 20 MeV electron beams to validate a Monte Carlo model for simulating the emittance and transmission of Cerenkov radiation in optical fibres. We show that fewer than 0.01 Cerenkov photons are emitted and guided per 225 MeV proton penetrating the optical fibre, and that the Cerenkov signal in the optical fibre is completely negligible at the Bragg peak. Furthermore, on taking the emittance and guidance of both fluorescence and Cerenkov photons into account, it becomes evident that the reported quenching-free signal in PMMA-based optical fibres during proton irradiation is due to fluorescence.

AB - Developments of innovative strategies for the fabrication of stretchable sensors are of crucial importance for their applications in wearable electronic systems. In this work, we report the successful fabrication of stretchable capacitive sensors using a novel 3D printing method for highly sensitive tactile and electrochemical sensing applications. Unlike conventional lithographic or templated methods, the programmable 3D printing technique can fabricate complex device structures in a cost-effective and facile manner. We designed and fabricated stretchable capacitive sensors with interdigital and double-vortex designs and demonstrated their successful applications as tactile and electrochemical sensors. Especially, our stretchable sensors exhibited a detection limit as low as 1 * 10-6 M for NaCl aqueous solution, which could have significant potential applications when integrated in electronics skins. PMID- 29446762 TI - Investigation of growth parameters influence on self-catalyzed ITO nanowires by high RF-power sputtering. AB - ITO nanowires have been successfully fabricated using a radio-frequency sputtering technique with a high RF-power of 250W. The fabrication of the ITO nanowires has been optimized through the study of oxygen flow rates, temperatures and RF-power. The difference in the morphology of the ITO nanowires prepared by using a new target and a used target has been first observed and the mechanism for the difference has been discussed in detail. A hollow structure and air voids within the nanowires are formed during the process of the nanowire growth. The ITO nanowires fabricated by this method has demonstrated good conductivity (15Omega/sq) and a transmittance of more than 64% at a wavelength longer than 550nm after annealing. Furthermore, detailed microstructure studies show that the ITO nanowires exhibit a large number of oxygen vacancies. As a result, it is expected that they can be useful for the fabrication of gas sensor devices. PMID- 29446763 TI - Ferroelectric nanoparticle-embedded sponge structure triboelectric generators. AB - We report high-performance triboelectric nanogenerators (TENGs) employing ferroelectric nanoparticles (NPs) embedded in a sponge structure. The ferroelectric BaTiO3 NPs inside the sponge structure play an important role in increasing surface charge density by polarized spontaneous dipoles, enabling the packaging of TENGs even with a minimal separation gap. Since the friction surfaces are encapsulated in the packaged device structure, it suffers negligible performance degradation even at a high relative humidity of 80%. The TENGs also demonstrated excellent mechanical durability due to the elasticity and flexibility of the sponge structure. Consequently, the TENGs can reliably harvest energy even under harsh conditions. The approach introduced here is a simple, effective, and reliable way to fabricate compact and packaged TENGs for potential applications in wearable energy-harvesting devices.

AB - OBJECTIVES: There is an increasing need to identify reliable biomarkers for distinguishing Crohn's disease (CD) from other gastrointestinal disorders sharing similar clinical and pathological features. This study aimed at evaluating the diagnostic potential of antibodies to zymogen granule glycoprotein GP2 (aGP2) in a large, well-defined Chinese cohort with a special focus on their role in discriminating CD from intestinal Behcet's disease (BD) and intestinal tubercolosis (ITB). METHODS: A total of 577 subjects were prospectively enrolled, including 171 patients with CD, 208 patients with ulcerative colitis (UC), 71 with BD, 57 with ITB and 70 healthy controls (HC). aGP2 and anti-Saccharomyces cerevisiae antibodies (ASCA) were determined by ELISA. Perinuclear antineutrophil cytoplasmic antibodies were tested by indirect immunofluorescent assay. RESULTS: aGP2 IgG and IgA levels were significantly elevated in patients with CD compared with those in patients with UC, intestinal BD, and ITB and HC. Conversely, ASCA IgG levels were not different between CD and intestinal BD patients, whereas ASCA IgA levels did not discriminate CD from intestinal BD and ITB patients. aGP2 IgA and IgG displayed a better assay performance (larger areas under the curve) over ASCA IgA and IgG in differentiating CD from disease controls (P<0.05). ASCA IgA did not discriminate CD from disease controls. aGP2 IgA and/or IgG was significantly associated with penetrating disease (B3) and ileal CD (L1) (P<0.05), whereas ASCA IgA and/or IgG was not. CONCLUSIONS: In comparison with ASCA, aGP2 distinguishes CD from intestinal BD or ITB as disease controls more efficiently, aiding in the differential diagnosis of IBD. PMID- 29446766 TI - Are whole-exome and whole-genome sequencing approaches cost-effective? A systematic review of the literature. AB - PURPOSE: We conducted a systematic literature review to summarize the current health economic evidence for whole-exome sequencing (WES) and whole-genome sequencing (WGS). METHODS: Relevant studies were identified in the EMBASE, MEDLINE, Cochrane Library, EconLit and University of York Centre for Reviews and Dissemination databases from January 2005 to July 2016. Publications were included in the review if they were economic evaluations, cost studies, or outcome studies. RESULTS: Thirty-six studies met our inclusion criteria. These publications investigated the use of WES and WGS in a variety of genetic conditions in clinical practice, the most common being neurological or neurodevelopmental disorders. Study sample size varied from a single child to 2,000 patients. Cost estimates for a single test ranged from $555 to $5,169 for WES and from $1,906 to $24,810 for WGS. Few cost analyses presented data transparently and many publications did not state which components were included in cost estimates. CONCLUSION: The current health economic evidence base to support the more widespread use of WES and WGS in clinical practice is very limited. Studies that carefully evaluate the costs, effectiveness, and cost effectiveness of these tests are urgently needed to support their translation into clinical practice.

AB - Irritable bowel syndrome (IBS) is a common, heterogeneous disorder characterized by abdominal pain associated with changes in bowel habits. The pathogenesis of IBS is multifactorial and may relate to alterations in the gut microbiota, changes in visceral sensation and motility, and genetic and environmental factors. Administration of systemic antibiotics may increase the risk of IBS by altering gastrointestinal homeostasis. Therapeutic interventions for IBS with diarrhea that are thought to target alterations in the gut microbiota include the nonsystemic antibiotic rifaximin, the medical food serum-derived bovine immunoglobulin, prebiotics, probiotics, and dietary modification. SYN-010 is a modified-release statin formulation that reduces methane production by Methanobrevibacter smithii and is currently in development for the treatment of patients with constipation-predominant IBS. Use of these interventions in the management of patients with IBS may function to restore a healthy gut microbiota and ameliorate symptoms of IBS. PMID- 29446768 TI - Vascular cognitive impairment. PMID- 29446769 TI - Vascular cognitive impairment. AB - The term vascular cognitive impairment (VCI) was introduced around the start of the new millennium and refers to the contribution of vascular pathology to any severity of cognitive impairment, ranging from subjective cognitive decline and mild cognitive impairment to dementia. Although vascular pathology is common in elderly individuals with cognitive decline, pure vascular dementia (that is, dementia caused solely by vascular pathology) is uncommon. Indeed, most patients with vascular dementia also have other types of pathology, the most common of which is Alzheimer disease (specifically, the diffuse accumulation of amyloid beta plaques and neurofibrillary tangles composed of tau). At present, the main treatment for VCI is prevention by treating vascular diseases and other risk factors for VCI, such as hypertension and diabetes mellitus. Despite the current paucity of disease-modifying pharmacological treatments, we foresee that eventually, we might be able to target specific brain diseases to prevent cognitive decline and dementia. PMID- 29446767 TI - CLAPO syndrome: identification of somatic activating PIK3CA mutations and delineation of the natural history and phenotype. AB - PURPOSE: CLAPO syndrome is a rare vascular disorder characterized by capillary malformation of the lower lip, lymphatic malformation predominant on the face and neck, asymmetry, and partial/generalized overgrowth. Here we tested the hypothesis that, although the genetic cause is not known, the tissue distribution of the clinical manifestations in CLAPO seems to follow a pattern of somatic mosaicism. METHODS: We clinically evaluated a cohort of 13 patients with CLAPO and screened 20 DNA blood/tissue samples from 9 patients using high-throughput, deep sequencing. RESULTS: We identified five activating mutations in the PIK3CA gene in affected tissues from 6 of the 9 patients studied; one of the variants (NM_006218.2:c.248T>C; p.Phe83Ser) has not been previously described in developmental disorders. CONCLUSION: We describe for the first time the presence of somatic activating PIK3CA mutations in patients with CLAPO. We also report an update of the phenotype and natural history of the syndrome.

PMID- 29446772 TI - Production of ready-to-use few-layer graphene in aqueous suspensions. AB - Graphene has promising physical and chemical properties such as high strength and flexibility, coupled with high electrical and thermal conductivities. It is therefore being incorporated into polymer-based composites for use in electronics and photonics applications. A main constraint related to the graphene development is that, being of a strongly hydrophobic nature, almost all dispersions (usually required for its handling and processing toward the desired application) are prepared in poisonous organic solvents such as N-methyl pyrrolidone or N,N dimethyl formamide. Here, we describe how to prepare exfoliated graphite using a ball mill. The graphene produced is three to four layers thick and ~500 nm in diameter on average, as measured by electron microscopy and Raman spectroscopy; can be stored in the form of light solid; and is easily dispersed in aqueous media. Our methodology consists of four main steps: (i) the mechanochemical intercalation of organic molecules (melamine) into graphite, followed by suspension in water; (ii) the washing of suspended graphene to eliminate most of the melamine; (iii) the isolation of stable graphene sheets; and (iv) freeze drying to obtain graphene powder. This process takes 6-7 or 9-10 d for aqueous suspensions and dry powders, respectively. The product has well-defined properties and can be used for many science and technology applications, including toxicology impact assessment and the production of innovative medical devices. PMID- 29446773 TI - An experimental toolbox for characterization of mammalian collagen type I in biological specimens. AB - Collagen type I is the most abundant extracellular matrix protein, and collagen type I supramolecular assemblies (e.g., tissue grafts, biomaterials and cell assembled systems) are used extensively in tissue engineering and regenerative medicine. Many studies, for convenience or economic reasons, do not accurately determine collagen type I purity, concentration, solubility and extent of cross linking in biological specimens, frequently resulting in erroneous conclusions. In this protocol, we describe solubility; normal, reduced and delayed (interrupted) SDS-PAGE; hydroxyproline; Sircol collagen and Pierce BCA protein; denaturation temperature; ninhydrin/trinitrobenzene sulfonic acid; and collagenase assays and assess them in a diverse range of biological samples (e.g., tissue samples; purified solutions or lyophilized materials; 3D scaffolds, such as sponges and hydrogels; and cell media and layers). Collectively, the described protocols provide a comprehensive, yet fast and readily implemented, toolbox for collagen type I characterization in any biological specimen. PMID- 29446774 TI - Proteome-wide identification of ubiquitin interactions using UbIA-MS. AB - Ubiquitin-binding proteins play an important role in eukaryotes by translating differently linked polyubiquitin chains into proper cellular responses. Current knowledge about ubiquitin-binding proteins and ubiquitin linkage-selective interactions is mostly based on case-by-case studies. We have recently reported a method called ubiquitin interactor affinity enrichment-mass spectrometry (UbIA MS), which enables comprehensive identification of ubiquitin interactors for all ubiquitin linkages from crude cell lysates. One major strength of UbIA-MS is the fact that ubiquitin interactors are enriched from crude cell lysates, in which proteins are present at endogenous levels, contain biologically relevant post translational modifications (PTMs) and are assembled in native protein complexes. In addition, UbIA-MS uses chemically synthesized nonhydrolyzable diubiquitin, which mimics native diubiquitin and is inert to cleavage by endogenous deubiquitinases (DUBs). Here, we present a detailed protocol for UbIA-MS that proceeds in five stages: (i) chemical synthesis of ubiquitin precursors and click chemistry for the generation of biotinylated nonhydrolyzable diubiquitin baits, (ii) in vitro affinity purification of ubiquitin interactors, (iii) on-bead interactor digestion, (iv) liquid chromatography (LC)-MS/MS analysis and (v) data analysis to identify differentially enriched proteins. The computational analysis tools are freely available as an open-source R software package, including a graphical interface. Typically, UbIA-MS allows the identification of dozens to hundreds of ubiquitin interactors from any type of cell lysate, and can be used to study cell type or stimulus-dependent ubiquitin interactions. The nonhydrolyzable diubiquitin synthesis can be completed in 3 weeks, followed by ubiquitin interactor enrichment and identification, which can be completed within another 2 weeks. PMID- 29446775 TI - Carbon dots with efficient solid-state red-light emission through the step-by step surface modification towards light-emitting diodes. AB - Carbon dots (CDs) have attracted extensive attention over the past decade due to their excellent advantages. However, few attempts have been reported for realizing the long-wavelength emission, especially for obtaining efficient solid state red emission with high photoluminescence quantum yield (QY). Herein, we developed highly red light emitting CDs by the step-by-step surface modifications of the nitrogen-doped CDs. By introducing hexadecyltrimethyl ammonium bromide to modulate a red CD aqueous solution, the photoluminescence QY increases from 23.2% to 43.6%. Furthermore, we dispersed CDs in a PVP matrix for a solid-state film, where the solid-state quenching was effectively suppressed, and high QY (41.3%) of red light emission was achieved. Taking advantage of the as-prepared red light emitting CDs combining with the reported high quantum yield blue and green light emitting CDs, we realized UV-pumped WLEDs with tunable correlated color temperature from 7879 to 2961 K. Moreover, a high color rendering index (CRI) of 93 for WLEDs was realized, which is superior than the best records for the semiconductor quantum dot based WLEDs. Finally, the red light emitting CDs were demonstrated to have promising application as a red color converter in traditional YAG-based WLEDs to improve their CCT and CRI.

PMID- 29446777 TI - Very high commutation quality factor and dielectric tunability in nanocomposite SrTiO3 thin films with Tc enhanced to >300 degrees C. AB - We report on nanoengineered SrTiO3-Sm2O3 nanocomposite thin films with the highest reported values of commutation quality factor (CQF or K-factor) of >2800 in SrTiO3 at room temperature. The films also had a large tunability of dielectric constant (49%), low tangent loss (tan delta = 0.01) and a Curie temperature for SrTiO3 > 300 degrees C, making them very attractive for tunable RF applications. The enhanced properties originate from the unique nanostructure in the films, with <20 nm diameter strain-controlling Sm2O3 nanocolumns embedded in a SrTiO3 matrix. Very large out-of-plane strains (up to 2.6%) and high tetragonality (c/a) (up to 1.013) were induced in the SrTiO3. The K-factor was further enhanced by adding 1 at% Sc3+ (acceptor) dopant in SrTiO3 to a value of 3300 with the tangent loss being <=0.01 up to 1000 kV cm-1. PMID- 29446778 TI - Ir(iii) complex-based phosphorescence and electrochemiluminescence chemodosimetric probes for Hg(ii) ions with high selectivity and sensitivity. AB - Mercury, one of the most prevalent toxic metal elements, poses severe risks to human health and the environment. Several molecular probes have been developed for colorimetric and fluorometric detection of Hg(ii) ions. Nevertheless, development of a rapid, selective, and sensitive probe for Hg(ii) ions remains important. Herein, we report three Ir(iii) complex-based phosphorescence and electrochemiluminescence chemodosimeters for the selective detection of Hg(ii) ions. The acetylacetonate ancillary ligand of probe 1 reacts selectively with the Hg(ii) ion, inducing phosphorescence enhancement with a concomitant blue-shift. Meanwhile, the Hg(ii) ion selectively quenches the phosphorescence of probe 2. Probes 1 and 2 showed low detection limits (LOD) of 73 and 160 nM, respectively. In addition, the Hg(ii) ion level was successfully monitored by the electrochemiluminescence decrement of probe 9 with a good linear correlation between 0 and 40 MUM, with a detection limit of 170 pM. PMID- 29446784 TI - Clinical comparison between an opaque and a clear pit and fissures sealants: a 12 month split-mouth, randomized controlled study. AB - TRIAL DESIGN: We design a clinical splith-mouth, randomized controlled study, in which the retention of an opaque and clear pit and fissures sealants were evaluated and their effectiveness compared at 6 and 12 months of follow up. A secondary aim was to evaluate the possibility of using a fluorescence based intra oral camera through the clear sealant to monitor enamel demineralization. METHODS: Consecutive young adolescents with at least two molars with code 0, 1, 2 caries evidenced following the International Caries Detection and Assessment System (ICDAS II) were enrolled. A split-mouth randomized allocation was carried out. One skilled operator applied the sealant under 3.5 X magnification. A second operator evaluated clinical retention and performed the intra-oral camera assessments at 6 and 12 months follow up. RESULTS: A total of 42 patients, (20 males and 22 females, mean age 14.25) with 176 dental lesions were enrolled. Nine patients dropped out accounting for 26 teeth lost during follow up. Overall, a total of 150 sealed teeth were evaluated in the study. In 77 cases the clear sealant was used, while in 73 the opaque sealant was utilized. The opaque sealant rated 100% complete retention at 6 months, and 97.3% at 12 months, while the clear selant 91.8% and 85.9% respectively. Demineralization under clear selant was registered when sealant partial detachment occurred. CONCLUSIONS: The overall retention rate of an opaque sealant was higher than that of a clear sealant after 12 months of follow-up. This difference may partly be due to difficulty in clinical detection of clear sealants during follow-up. Fluorescence based intra oral camera seems useful to monitor enamel demineralization in clear sealant. PMID- 29446785 TI - Effects of salso-bromo-iodine thermal water in children suffering from otitis media with effusion: a randomized controlled pilot study. AB - BACKGROUND: Otitis media with effusion (OME) is an ear disorder defined by the presence of fluid in the middle ear without signs or symptoms of acute infection. The aim of this randomised and controlled pilot study was to evaluate whether the treatment with a watery salsobromo- iodine solution, administered by nasal douche, could induce ear healing better than isotonic saline in children with OME. METHODS: The study was randomized, single-blind, and controlled. Study group (40 children) was treated with salso-bromo-iodine thermal water solution and Control group (40 children) was treated with isotonic saline; both compounds were administered by nasal nebulization with Rinowash nasal douche twice/day for 10 days a month for 3 consecutive months. Tympanogram and audiometry were performed at baseline and after treatment. RESULTS: Salso-bromo-iodine therapy shows better and statistically significant trend after treatment when compared to control group both for tympanogram results with greater improvement (represented by type C tympanogram; p = 0.031) and healing (represented by type A tympanogram; p < 0.001) and audiometric results, with higher presence of patients with normal hearing (p = 0.029) and lower among patients with moderate hypoacusis (p = 0.014). CONCLUSIONS: The current randomized-controlled pilot study demonstrated that watery salso-bromo-iodine solution was effective in the treatment of children with OME. PMID- 29446786 TI - The synergistic effect between Positivity, socio-demographic factors and smoking cessation: results of a cohort study. AB - OBJECTIVE: To examine the extent to which a effect does exist between Positivity (POS), smoking and socio-demographic factors in determining quitting smoking in subjects participating in a Group Counselling Program (GCP) for smoking cessation. METHODS: 481 subjects were contacted through a telephone call. A logistic regression analysis was carried out. Possible interaction between sociodemographic variables and POS level was tested using the Synergism Index (SI). RESULTS: For individuals with a POS level over or equal to 3.4 the odds of being smoker was significantly higher among females (OR = 1.55), who smoked at home (OR = 2.16) and lower if there had children at home (OR = 0.53). For individuals with a POS level under 3.4, the only significant variable associated with smoking was beinga female (OR = 2.58). As far concerns the synergistic effect between the variables considered does exist between POS levels and having children at home (SI=1.13) and female gender (SI = 2.8). CONCLUSIONS: The synergistic effect between POS and sociodemographic factors adds evidence on the use of POS as possible determinants of individual happiness. PMID- 29446787 TI - The treatment of femoral fractures in children with cerebral palsy. AB - OBJECTIVE: The purpose of this study is to retrospectively evaluate a group of children affected by cerebral palsy with a recent femoral fracture, and to analyse the results and complications in relation to the treatment used. MATERIALS AND METHODS: The analysis was performed on 36 children (21 M, 15 F, 8 14 years old) with cerebral palsy (7 diplegia, 28 tetraparesis, 1 hemiplegia) with a metaphyseal or a diaphyseal femoral fracture. The patients were subdivided into two groups according to their Gross Motor Function Classification System (GMFCS) level: level 2-3 (9 patients) and level 4-5 (27 patients), evaluating the presence of complications and malunions for each group at the end of each follow up. RESULTS: The fractures were displaced in 24 patients and nondisplaced in 12 patients. In 26 cases the treatment involved a closed reduction and immobilisation in a long leg hip spica cast for 7 weeks, while in 10 cases the treatment involved an open reduction-internal fixation (ORIF) followed by a 3 week period in a plaster coated fracture bandage. CONCLUSIONS: Taking into consideration the maximum possible recovery of function, an ORIF is preferable to prevent malunion, particularly in distal metaphysis and distal shaft fractures. In the GMFCS level 2-3 patients, surgery has allowed to recover, or at least maintain, the pre-fracture functional level, while in patients with GMFCS level 4 5, it has allowed to reduce the immobilisation times and prevent the development of decubitus lesions. PMID- 29446788 TI - The potential role of herbal products in the treatment of Parkinson's disease. AB - Parkinson's disease (PD) is a multifactorial disorder of the nervous system in which there is a progressive loss of dopaminergic neurons. There is a disturbance in the movement in PD and these include resting tremors, rigidity, bradykinesia or akinesia, disturbance, posture and freezing (motor block). The substantia nigra and other parts of the brain are commonly affected. The disorder could be related to oxidative stress and there is an important role of reactive oxygen species (ROS). A number of herbal products contain active components which are known to possess antioxidant action. Hence, the potential role of herbal products in treating PD cannot be undermined. In the present narrative review, the main aim is to discuss the pathogenesis of PD, define the role of different potential herbal extracts on its pathogenesis which may form the basis of treatment. We also discuss in detail the active chemical compounds present each herb which are effective in the treatment of PD. These herbs include Baicalei, Erythrina velutin, Resveratrol, Peganum Harmal, Curcuma longa (Zingiberaceae), Carthamus tinctorius L. (Safflower), Pueraria lobate, Juglandis Semen (Walnut), Tianma Gouteng Yin (TGY), Lycium barbarum L fruit, Mucuna pruriens (Velvet bean), Chunghyuldan (CHD), Paeoniae Alba Radix. The present review may be beneficial for designing future drugs for effective treatment of PD. PMID- 29446789 TI - Medical advancements: emergency contraception (EC). Medico-legal implications of EC on adolescents. AB - The article's main focus is documenting what the best options are in order to make sure that minors are allowed to play a key role in the management of issues arising from the use of emergency contraception. In that regard, there is a lack of clean-cut legislative measures and, although there are several legal and ethical norms designed to get parents or legal guardians involved in such decisions, there seems to be an increasingly widespread tendency to give weight to the minor's will, thus acknowledging her decision-making capacity. Lastly, the paper's authors undertake a thorough examination as to what the duties of doctors are, and the measures that need to be put in place in order to safeguard the minor patients' conditions. They arrive at the conclusion that emergency contraception is suitable for minors even in absence of the stated consent from their parents or guardians, but it is of utmost importance to implement adequate measures aimed at the provision of proper care, prevention and education. PMID- 29446790 TI - Assisted heterologous fertilization and the right of donorconceived children to know their biological origins. AB - The paper's main goal is to elaborate on the ethical issues that heterologous fertilization has raised as to the right of children thus conceived to find out about their origins. Such a quandary revolves around the following questions: Is it the right thing to inform the child as to the way he or she was conceived? If it is, does said child have a right to know his or her biological parent and genetic background too? Authors point out that there is no unanimity of judgment among experts, and it is worth weighing all reasons in favor and against acknowledging the children's right to full knowledge of their biological parents' data. Laws regulating the issue in different countries vary substantially as well. Therefore, the authors advocate for shared legislation, centered on the children's best interest.

AB - Anemia is a pervasive problem in pediatrics and evaluating for it is considered part of standard care for all pediatric patients. If left untreated, it can cause significant problems for children and many of the detriments can be long lasting. Although iron deficiency anemia is the most common form of pediatric anemia, it is important to keep the broad differential in mind for those in whom the history suggests an alternate diagnosis or who do not respond to standard treatment with iron supplementation. This article gives a basic overview of anemia in children with a focus on iron deficiency. [Pediatr Ann. 2018;47(2):e42-e47.]. PMID- 29446793 TI - Headaches in Children. PMID- 29446794 TI - Migraine Variants in Children. AB - Migraine in children can manifest in ways that are markedly different from adult migraines. In children, migraine variants are often unaccompanied by headache and include conditions such as cyclic vomiting and abdominal migraine. Children who experience these conditions are often thought to have a disorder of the gastrointestinal tract, and when evaluation is unremarkable they may be diagnosed as having a conversion reaction. Complicated migraines, on the other hand, are often accompanied by focal neurological symptoms such as ataxia, hemiparesis, or altered level of consciousness that evoke great consternation in the examining clinician. Certain episodic syndromes that may hold interest to pediatricians are also discussed in this article, mostly to emphasize the ambiguity that still surrounds these disorders, such as migraine triggered by trauma. The cardinal rule that most of these disorders are diagnoses of exclusion and can only be confirmed after extensive evaluation, either by the pediatrician or pediatric neurologist, is emphasized. [Pediatr Ann. 2018;47(2):e50-e54.]. PMID- 29446795 TI - Management of Pediatric Migraine: Current Therapies. AB - Migraine is one of the most common neurologic conditions in pediatrics. It can be a significant stressor, causing absences from school and interruption of parents' work and family schedules. The mainstay of treatment remains educating patients about healthy lifestyle practices and the influences of sleep, stressors, and hydration on triggering migraine attacks. Psychological therapies such as biofeedback or cognitive-behavioral therapy may be beneficial in some patients, especially those with prominent psychological comorbidities. New advances in the pathophysiology of migraine and additional pediatric approval of abortive therapy with triptans have led to significant advances in the management of migraine in children. Some challenges to preventive therapy were recently noted with the negative results obtained in the Childhood and Adolescent Migraine Prevention Study, which compared prescription drugs to placebo. Inherent differences between adult and pediatric headaches, with shorter duration of pediatric migraine and prominent placebo effect, present recurring challenges for clinicians. [Pediatr Ann. 2018;47(2):e55-e60.]. PMID- 29446796 TI - Posttraumatic Headache. AB - After sustaining a concussion or mild traumatic brain injury, headaches are one of the most common complaints. The pathophysiologic changes that occur in the setting of injury likely contribute to or cause posttraumatic headaches. Posttraumatic headaches often present as migraine or tension-type headaches. Unlike pain from other types of injuries, headaches following mild traumatic brain injury are more likely to persist. Preexisting conditions such as migraine and mood disorders may influence posttraumatic headache and complicate management. Patients are at high risk to overuse abortive medications and develop medication overuse headache. Headache hygiene and early education are essential for effective management. Abortive medications include nonsteroidal anti inflammatory drugs and triptans. Preventive medications include tricyclic antidepressants and antiepileptics. Patients who fail outpatient therapies may benefit from referral for intravenous medications in the emergency department. Patients with persistent posttraumatic headache may benefit from multimodal treatments including physical rehabilitation and pain-focused cognitive behavioral therapies.

AB - Migraine and tension-type headaches are common primary headache disorders encountered among children and adolescents presenting to a pediatric clinic. At times, children present with a headache with unusual or peculiar features that can be alarming and perplexing. These can be in the form of a brief stabbing headache with lacrimation in one eye or a continuous headache locked to one side of the head or face. These headache syndromes tend to be more common among adults but, on occasion, are known to occur or have their onset during childhood. This review outlines some of the uncommon primary headache disorders in children and adolescents that may be encountered in a pediatric clinic. Knowledge of these interesting conditions may avert the need for immediate neurological consultation and prevent delays in initiating specific therapy. [Pediatr Ann. 2018;47(2):e69 e73.]. PMID- 29446798 TI - Life-Threatening Headaches in Children: Clinical Approach and Therapeutic Options. AB - Life-threatening headaches in children can present in an apoplectic manner that garners immediate medical attention, or in an insidious, more dangerous form that may go unnoticed for a relatively long period of time. The recognition of certain clinical characteristics that accompany the headache should prompt recognition and referral to an institution equipped with neuroimaging facilities, pediatric neurosurgeons, and neurologists. Thunderclap headaches, which reach a peak within a very short period of time, may be the presenting feature of conditions such as arterial dissection, venous sinus thrombosis, and reversible cerebral vasoconstriction syndrome, which can be addressed by specific pharmacological options instituted in an intensive care setting. On the other hand, subacute to chronic headaches that are accompanied by focal neurological signs, such as abducens nerve palsy, restriction of upward gaze, or papilledema, may be indicative of the need for urgent imaging and neurosurgical referral.

Clinical presentation of AIH in children is highly variable. It can present acutely, chronically, or silently. There are two main types of AIH-type 1 and type 2, which are differentiated and defined by the presence of specific autoantibodies. AIH eventually progresses to cirrhosis when left untreated, and occasionally even with treatment. AIH must be suspected and excluded in all children presenting with signs of acute, prolonged, or severe liver disease. The diagnosis of AIH is made by a combination of clinical manifestations, laboratory evaluation, histopathology, and the exclusion of other more common liver diseases. The best outcome for AIH is dependent on early diagnosis as well as early initiation of immunosuppressant therapy. [Pediatr Ann. 2018;47(2):e81 e86.]. PMID- 29446800 TI - Biology of Vibrio cholera. Editorial overview. AB - In this monographic issue, we have the pleasure to present contributions from six of the leading laboratories at the forefront of Vibrio cholerae genetics, ecology and evolution, together with a brief tribute by Diego Romero to Doctor Jaime Ferran y Clua, a pioneering Spanish bacteriologist who developed the first vaccine against this pathogen. V. cholerae is a free-living aquatic bacterium that interacts with and infects a variety of organisms. In humans it causes cholera, the deadly diarrhoea that was responsible for millions of deaths during seven pandemics since 1817, and still thousands every year. The Boucher lab presents a study of the ecology, evolution and dispersal of pandemic V. cholerae biotypes in relation to environmental reservoirs. They show how both species specific and lineage-specific genetic determinants play a role in the ability of V. cholerae strains to cause pandemics, having evolved gradually over centuries. One of the key aspects that makes a particularly successful pathogen is its genomic plasticity. The V. cholerae genome contains a superintegron (SI) that is involved in development and dissemination of antibiotic resistance genes among diverse bacterial species, permitting population expansion in challenging conditions. Escudero and Mazel review the SI as a true hotspot of V. cholerae's genomic diversity and low-cost memory of adaptive functions in its complex lifestyle and ecology. Another remarkable aspect of V. cholerae 's genetics is the presence of two chromosomes. Segregation and division in multi-chromosomal becteria is relatively complex, and V. cholerae remains the paradigm. Espinosa and colleagues review the cell cycle of V. cholerae , comparing and contrasting with that of E. coli . In addition to genome plasticity, V. cholerae uses a variety of attack/defence strategies to compete and thrive in different niches, through interaction with bacteriophages, bacteria and eukaryotes. The role of phages in the life cycle of V. cholerae has been increasingly recognized and investigated over the past decade. Andrew Camilli and colleagues take us through the exciting evolutionary arms race between V. cholerae and virulent bacteriophages, based both on mechanisms of phage resistance in the bacterium and a unique phage-encoded CRISPR-Cas system used to counteract this resistance. Finally, the authors discuss the impact of these predator-prey dynamics in the context of infection, and their use as a strategy to limit cholera transmission within a community. In regards to its ability to coexist with other microbes, V. cholerae can produce effectors that are either released to the extracellular media, or delivered via intimate cell-to-cell contact such as those injected via the type VI secretion system (T6SS). The Pukatzki lab reviews the versatility of the T6SS to produce different combinations of such effectors, which establishes the strains of V. cholerae that can co-exist in the environment. After killing a cell, its DNA is released and incorporated by natural competence into other living cells, thereby being a potential source of diversification for V. cholerae's T6SS effectors. Finally, I revisisit the discovery of non-canonical D amino acids, recently identified effectors secreted by V. cholerae which have increasingly been shown to be important in enhancing the ability of the bacterium to colonize and persist in a particular niche. I focus on recent observations that suggest different D-amino acids influence distinct cellular processes in bacteria, and dis cuss their role in modulating environmental bacterial biodiversity. PMID- 29446801 TI - Emergence, ecology and dispersal of the pandemic generating Vibrio cholerae lineage. AB - Although cholera is an ancient disease that first arose at least half a millennium ago, it remains a major health threat globally. Its pandemic form is caused by strains from a single lineage of the bacterium Vibrio cholerae. The ancestor of this lineage harbored several distinctive characteristics, the most notable being the O1 antigen polysaccharide. This lineage generated two biotypes, first Classical, responsible for six pandemics, and later El Tor, responsible for the seventh and ongoing pandemic. Just as El Tor replaced Classical as the main cause of outbreaks in the last fifty years, several variants of El Tor have evolved and displaced their predecessors worldwide. Understanding the ecology, evolution and dispersal of pandemic V. cholerae is central to studying this complex disease with environmental reservoirs. Here, we present recent advancements of our knowledge on the emergence and spread of the pandemic generating lineage of V. cholerae in the light of established eco-evolutionary observations. Specific ecological interactions shape seasonal cholera, playing a role in the abundance and distribution of its causative agent. Both species specific and lineage-specific genetic determinants play a role in the ability of V. cholerae strains to cause pandemics with seasonal outbreaks, having evolved gradually over centuries. On the basis of the current understanding, we outline future threats and changes in biogeographical and genomic-based investigation strategies to combat this global problem. PMID- 29446802 TI - Mechanisms of the evolutionary arms race between Vibrio cholerae and Vibriophage clinical isolates. AB - This review highlights recent findings on the evolutionary arms race between the causative agent of cholera Vibrio cholerae and virulent bacteriophages (phages) ICP1, ICP2, and ICP3 isolated from cholera patient stool samples. We discuss mechanisms of phage resistance such as a unique phage-inhibitory chromosomal island and mutations that affect phage receptor expression. We also discuss the molecular characterization of ICP1 and its unique CRISPR-Cas system, which it uses to combat the phage-inhibitory chromosomal island. The role of phages in the life cycle of V. cholerae has been increasingly recognized and investigated in the past decade. This article will review hypotheses as to how the predator-prey relationship may have an impact on infections within individuals and on the self limiting nature of cholera epidemics. In addition, we put forth a strategy of using phages as an intervention to reduce household transmission of cholera within a community. PMID- 29446803 TI - Coordination between replication, segregation and cell division in multi chromosomal bacteria: lessons from Vibrio cholerae. AB - Bacteria display a highly flexible cell cycle in which cell division can be temporally disconnected from the replication/segregation cycle of their genome. The accuracy of genetic transmission is enforced by restricting the assembly of the cell division apparatus to the low DNA-density zones that develop between the regularly spaced nucleoids originating from the concurrent replication and segregation of genomic DNA. In most bacteria, the process is simplified because the genome is encoded on a single chromosome. This is notably the case in Escherichia coli, the most well studied bacterial model organism. However, ~10% of bacteria have domesticated horizontally acquired mega-plasmids into extra numerous chromosomes. Most of our current knowledge on the cell cycle regulation of multi-chromosomal species derives from the study of replication, segregation and cell division in Vibrio cholerae, the agent of the deadly epidemic human diarrheal disease cholera. A nicety of this model is that it is closely related to E. coli in the phylogenetic tree of bacteria. Here, we review recent findings on the V. cholerae cell cycle in the context of what was previously known on the E. coli cell cycle. PMID- 29446804 TI - T6SS intraspecific competition orchestrates Vibrio cholerae genotypic diversity. AB - Vibrio cholerae is a diverse species that inhabits a wide range of environments from copepods in brackish water to the intestines of humans. In order to remain competitive, V. cholerae uses the versatile type-VI secretion system (T6SS) to secrete anti-prokaryotic and anti-eukaryotic effectors. In addition to competing with other bacterial species, V. cholerae strains also compete with one another. Some strains are able to coexist, and are referred to as belonging to the same compatibility group. Challenged by diverse competitors in various environments, different V. choleare strains secrete different combination of effectors - presumably to best suit their niche. Interestingly, all pandemic V. cholerae strains encode the same three effectors. In addition to the diversity displayed in the encoded effectors, the regulation of V. cholerae also differs between strains. Two main layers of regulation appear to exist. One strategy connects T6SS activity with behavior that is suited to fighting eukaryotic cells, while the other is linked with natural competence - the ability of the bacterium to acquire and incorporate extracellular DNA. This relationship between bacterial killing and natural competence is potentially a source of diversification for V. cholerae as it has been shown to incorporate the DNA of cells recently killed through T6SS activity. It is through this process that we hypothesize the transfer of virulence factors, including T6SS effector modules, to happen. Switching of T6SS effectors has the potential to change the range of competitors V. cholerae can kill and to newly define which strains V. cholerae can co-exist with, two important parameters for survival in diverse environments. PMID- 29446805 TI - Genomic Plasticity of Vibrio cholerae. AB - Vibrio cholerae is one of the deadliest pathogens in the history of humankind. It is the causative agent of cholera, a disease characterized by a profuse and watery diarrhoea that still today causes 95.000 deaths worldwide every year. V. cholerae is a free living marine organism that interacts with and infects a variety of organisms, from amoeba to humans, including insects and crustaceans. The complexity of the lifestyle and ecology of V. cholerae suggests a high genetic and phenotypic plasticity. In this review, we will focus on two peculiar genomic features that enhance genetic plasticity in this bacterium: the division of its genome in two different chromosomes and the presence of the superintegron, a gene capture device that acts as a large, low-cost memory of adaptive functions, allowing V. cholerae to adapt rapidly. PMID- 29446806 TI - Divergent functional roles of D-amino acids secreted by Vibrio cholerae. AB - The L-forms of amino acids are used in all kingdoms of life to synthesize proteins. However, the bacterium Vibriocholerae, the causative agent of cholera, produces D-amino acids which are released to the environment at millimolar concentrations. We baptized these D-amino acids as non-canonical D-amino acids (NCDAAs) since they are different from those (i.e. D-alanine and D-glutamate) normally present in the bacterial cell wall. In V. cholerae, production of NCDAAs relies on the BsrV enzyme, a periplasmic broad spectrum racemase. BsrV multispecific activity, produces of a wide range of distinct D-amino acids. Using a combination of genetics and molecular physiology approaches we have demonstrated that NCDAAs target different cellular processes which may function as part of a cooperative strategy in vibrio communities to protect non-producing members from competing bacteria. Because NCDAA production is widespread in bacteria, we anticipate that NCDAAs are relevant modulators of microbial subpopulations in diverse ecosystems.

AB - In a context of economic difficulties, the Tunisian government is required to find solutions to meet the expectations of the population. Health sector is one of the critical areas requiring radical reform. The objective of this paper is to find the place of public private partnership project in the harmonious development of both public and private sectors in Tunisia. Indeed, the Tunisian health system consists of two main sectors: the public sector, and the private sector, booming since the 90s. Tunisian infrastructure and staff resources distribution is characterised by a very significant regional disparity, to the detriment of the interior regions, which is more pronounced in the private sector. This area, considered innovative and responsive, captures the local wealthy clientele, and the foreign highly specialized care seekers. It wins over the best healthcare providers, inspite of some reported claims against pricing abuses leading to user's lack of confidence. As for the public sector under funded, handicapped by red tape and some forms of lack of transparency and lobbying, it can not cope with the influx of customers of poor and middle classes. The relationship between the two sectors misses often. The current challenge in the Tunisian health sector is how can public and private sectors combine and harmonize their efforts to achieve common interest objectives. The public-private partnership, is a process helping the state to involve private investors in the realization of public interest projects and develop long term contracts. So, the two sectors will share resources and technical expertise and will access to further advantages. However, it is essential to establish clear and effective legal and institutional frameworks governing private participation in the public sector. PMID- 29446809 TI - Cost of common low back pain and lumbar radiculopathy in rheumatologic consultation in Lome. AB - BACKGROUND: The cost of low back pain was the subject of few studies in black Africa. AIM: To assess the cost of common low back pain and lumbar radiculopathy in Lome. METHODS: A six months study was realised in the rheumatologic department of CHU Sylvanus Olympio. 103 consecutive patients suffering from a common low back pain or lumbar radiculopathy were included. To assess direct, indirect and non-financial costs they were questioned about their expense during the year. RESULTS: Financial cost of common low back pain and lumbar radiculopathy amounted to 107.2 $ US (extremes: 5.8 and 726.1 $ US). This amount, quadruple of guaranteed minimum wage, felled under two headings: direct cost (56.3 $ US; 53% of total sum), indirect cost (50.3 $ US; 47% of total sum). Non-financial cost were: disruption in daily activities (94%), impact in emotional and sexual life (59%), impact on the family's budget (69%), abandon of family's projects (58%) or of leisure (42%). CONCLUSION: In black Africa top priority is given to the fight against infectious diseases those cause an important mortality. But common low back pain and lumbar radiculopathy, those have social and economic impact, should be given more attention. PMID- 29446810 TI - Postoperative Endophtalmities: therapeuthic results and Early vitrectomy. AB - BACKGROUND: Postoperative endophthalmitis is a public health issue due to its bad prognosis; its treatment is both surgical and medical. Classically, surgical treatment was done if visual acuity is limited to light perception only. AIM: To evaluate therapeutic results Of postoperative endophtalmitieS and to Compare therapeutics almost used intravitreal injection of antibiotics versus early vitrectomy. METHODS: It's a retrospective comparative study includIng 120 cases of acute postoperative endophthalmitis hospitalized in a referral ophthalmology department between July 2007 and June 2013. A comparison was conducted between two groups of 24 and 94 patients; the first-line treatment was early vitrectomy for the first group and intravitreal antibiotic injection alone for the second group. RESULTS: The overall incidence rate was 0.38 %, Streptococcus and Staphylococcus Epidermidis where the most common bacterial strain (16 patients each). The treatment outcome was very favorable for 11 patients with final visual acuity higher or equal to 2/10, the outcome was intermediate for 43 patients and poor for 66 patients because of final visual acuity lower than or equal to 1/20, loss of media transparency or anatomical or functional loss of the eye. The prognostic factors statistically correlated to treatment outcome where intense initial inflammation (p<0.001), high bacterial virulence (p=0.002), bacteria culture positive to Streptococcus (p=0.024), a defectuous operative incision (p= 0.012), age over 80 (p=0.022) and posterior capsule rupture (p=0.013). Early vitrectomy group (group1) achieved a higher percentage of good outcome (60% vs 41.5%, p=0.098 ). CONCLUSION: Functional result is better in the Vitrectomy group than in the antibiotic intravitreal injections group whereas not Statically signifiant. PMID- 29446811 TI - Nosocomial infections: current situation in a resuscitation-unit. AB - BACKGROUND: The nosocomial infection (NI) is defined as an infection that is not present or incubating on admission in establishment of care. It can be caused by the patient's germs, care personnel or hospital environment. Multidrug resistant (MDR) bacteria are particularly common in intensive care units that lead to a serious infections and increase morbidity, mortality and cost of care. PURPOSE: To identify the epidemiological characteristics of NI, the predisposing factors, the antimicrobial sensitivity pattern of isolated bacteria and the impact on morbidity and mortality. METHODS: Observational study over the year 2013. All infected patients hospitalized for at least 48 hours were included unless infection has been documented at admission. The type of sampling and bacteriological analyzes were performed based on the infection site according to the classification of Coordination Committee for the Fight against Nosocomial Infection of 2012. Statistical analysis was performed using the SPSS software 20. A p value <0.05 was considered significant. RESULTS: 63 patients were included with an average age of 51 years and SAPS II at 38. 95% of included patients were ventilated and 100% had a central catheterization. 164 infectious episodes were documented. The number of infection episodes per patient was statistically correlated with the length of stay. The most common isolated microorganism was Acinetobacter baumannii. It remains sensitive to colistin in 87.5% of cases. It was noted an emergence of Carbapenemase Producing Enterobacteriaceae (12%). The major identified risk factors were: previous organ failure, sepsis and catecholamines use (respective OR at 2.72, 2.56 and 2.15). Death was attributed to nosocomial infection in 36.6% of cases. CONCLUSION: The incidence of nosocomial infections is constantly rising in intensive care units. Pneumonia remains the most common infectious site. Contributing factors are an anterior organ failure, sepsis and catecholamines use. Approximately, one infected patient among three died by nosocomial infection. PMID- 29446812 TI - Surgical management of primary crohn's disease. descriptive study about 226 patients. AB - BACKGROUND: The surgery is required in more than 80% of patients with Crohn's disease (CD). Studies before confirm the specific genetic variation of CD in the Tunisian population compared with the others ethnic groups. AIM: This article aims to study the epidemiological, anatomical and therapeutic principles of surgical forms of CD in a cohort of Tunisian patients. METHODS: We report a retrospective study from January 1998 to September 2010 that studied 226 patients originated only from Tunisia (in North Africa), operated on for MC. We had been interested in epidemiological, anatomical, clinical, therapeutic, topographic progression of the disease, the procedure and the postoperative follow-up. RESULTS: The median age was 33 years. The average time between the onset of the disease and the surgical procedure was 31 months. The diagnosis of CD was established preoperatively in 213 patients (94%). The diagnosis was made intraoperatively because of an acute complication in 5 cases (2.2%) and postoperatively in 8 cases (3.5%). The most common location was the ileocecal junction in 184 cases (81.4%). Achieving the most common was the mixed form (stricture and fistula) in 123 cases (54.4%). Operative mortality was 0.04% (n = 1). Specific morbidity was 8.4% (n = 19). In long term, a surgical recurrence was noted in 17 patients (7.5%). In multivariate analysis the independent risk factors for surgical recurrence were: smooking (p = 0.012, ORs = 3.57) and post operative medical treatment (p = 0.05, ORs = 2.6). CONCLUSIONS: Achieving stenosing and fistulizing the ileocecal junction is the most frequent surgical form in Crohn's disease. Our series is unique for a lower rate of the postoperative recurrence (7.5%). PMID- 29446813 TI - Ultrasound monitoring of cervical length in twin Pregnancies. AB - BACKGROUND: Preterm delivery is the major cause of adverse outcomes in twin pregnancy. A shortened cervix at 20-24 weeks of amenorrhea is a good predictor of preterm birth in asymptomatic patients. However, there are no recommendations for serial cervical length measurements for these high risk pregnancies. OBJECTIVES: To evaluate the benefits from monthly cervical length monitoring in asymptomatic twin pregnancies. METHODS: This was a prospective study. We compared two groups of twin pregnancies (groupe 1: patients with a monthly and systematic transvaginal ultrasound measurement of the cervical length and groupe2 : patients without monitoring of cervical length) in terms of premature labor screening, mean gestational age at the diagnosis of preterm labor, time saved by tocolysis in case of preterm labor and mean gestational age at delivery. RESULTS: Ninety nine twin pregnancies were included: 35 patients had a systematic, monthly cervical length (group1) and 64 women had a traditional prenatal care without monitoring of cervical length (group2). A significant relationship between a cervical length measured between 22 and 24 weeks of amenorrhea inferior to 30 mm and preterm labor with a high specificity (100%) and a high positive predictive value (100%). The sensitivity remains average (45%).A significant benefit was demonstrated through this systematic ultrasound measurement of cervical length for the screening of preterm labor (p=0.018), the time saved by tocolysis (p=0.023), as well as the medium gestational age at birth (p=0.046). CONCLUSION: Serial cervical length measurements seems to be a significant predictor of early preterm birth in asymptomatic twin pregnancies. PMID- 29446814 TI - Nerve surgery in obstetric brachial plexus palsy, report of 68 cases. AB - BACKGROUND: Obstetric brachial plexus palsy aredue to elongation of the brachial plexus during delivery by increasing thedistance between the head and shoulder. The majority of paralysis recoverspontaneously, but in some cases, nerve repair is necessary. The timing of thisnerve surgery and criteria for its indication are topics of discussion in theworld literature.The aim of this study is to askdirections and to evaluate the contribution of nerve surgery in improving theprognosis of this disease. METHODS: This is a retrospective study thathas interested 68 cases of obstetric brachial plexus palsy who needs a nerverepair, collected over a 8 year-period (2004 - 2011). We analyzed the musclequotes and evaluate the functions of the shoulder, elbow and hand pre and postoperative. A minimum 12 months'follow-up was observed. RESULTS: Seventy-eight patients werecollected, 33 boys and 35 girls with a 62 days mean age at first consultationand a mean birth weight of 4187 grams . The presentation was cephalic in 66 cases. Theright side was interested in 66%. Clinically, we reported 50% of total brachialplexus palsy and 50% of C5-C6 palsy.The mean age at time of surgery was 9 months 10 days. Preoperatively, the shoulder was listed 0 or 1 according to Gilbert classification in 70% of cases in the C5-C6 plasy and 90% of the total brachial palsy. After a mean follow up of 30 months, the rate was respectively 9% and 15%. In 75% of cases of total brachial palsy, the hand was listed 0 according to Raimondi scale, while in postoperative, 65% of cases, the hand was listed 2 and 3 according to Raimondi scale. Nerve rupture was the predominant lesion on the C5 and C6 root while fibrosis was predominant on C7, C8 and T1 roots. We noted 6 complications including respiratory distress. CONCLUSIONS: The nerve repair should not beperformed too early or too late. Too soon, we may operate those who can have aspontaneous recovery. Too late, the installation of the degeneration of motorendplates and muscle atrophy render unnecessary nerve repair. The absence ofbiceps clinical recovery in the 6th month of life and the presence of root-wrenching signs represented the absolute surgical indications. Its results areencouraging and improve functional outcome. PMID- 29446815 TI - Fetoplacental malformations and abnormalities. A retrospective analysis of 398 cases. AB - BACKGROUND: The fetoplacental examination is actually very important and sometimes necessary to confirm or correct prenatal diagnosis. AIM: to deduce a list of indications of fetoplacental examination and to determine the type and frequency of malformations found. METHODS: a retrospective study including 398 consecutive fetoplacental examinations, including abortions, stillbirths and children died perinatally. The cases were referred in the department of pathology of the M. Slim Hospital (North Tunis) from 1992 and 2012. RESULTS: The mean maternal age was 32,58 years. The average gravidity was 2,65 and the average rate was 1,48. Maternal conditions were dominated by preeclampsia. The main indication motivating the request for fetoplacental examination was a spontaneous abortion in 45,73% of cases. The rate of stillbirths was 15,61% and that of children who died in the perinatal period was 13,28%. The sex ratio was 1,4 and the medium term was 19,38 SA. 170 fetuses had abnormalities (43,14%). The most frequent abnormalities were chromosomal aberrations (27,64%), followed by facial abnormalities (25,88%) and central nervous system abnormalities (18,82%). We examined 283 placentas, 49% of them contained abnormalities. Ischemic lesions were the main placental abnormalities (41%). CONCLUSIONS: An efficient fetopathological examination should be as complete as possible, including examination of placenta. Everything must be integrated into a data collection and complete clinical information. PMID- 29446816 TI - Atrophic tear retinal detachment: clinical characteristics and surgical treatment results at long term. AB - AIM: to analyse clinical and epidemiological characteristics of atrophic tear retinal detachment (ATRD) and evaluate anatomical and functional results. METHODS: Retrospective study of 48 cases underwent primary scleral buckling for ATRD. Mean follow up was 80,52 months. RESULTS: ATRD represented 7% of all reghmatogenous RD. Mean age of patients was 38 years and 7 months. Age was less than 40 years in 62,5% of patients. Male predominance was noted. Myopia was noted in 67% of cases and 78,12% presented high myopia. Mean delay of consultation was 7 months ranging from 1 and 60 months. Visual acuity was ranged between light perception to 10/10. The AT number in eye varied between1 to 15 (mean 3 tears). The seat of AT was preferentially in inferior temporal quadrants than superior one. Maculae was detached in 87,5% of cases. All patients underwent scleral buckling: longitudinal buckle was performed in 27% of cases, radial sponge was put on in 8,3% of eyes and circumferential one was made in 64,5% of cases. Sub retinal fluid was punctured in 75% od cases. Retinal reattachment was obtained in all cases; after one surgery in 95,83% of cases. Redetachment was observed in 2 cases: it was linked with unknown AT. Visual acuity was improved in 83,3% of cases. It was more than 5/10 in 14,6% of cases. Postoperative hypertonia was observed in 18,75% of cases. Choroidal detachment was observed in one case and it was resolved spontaneously. Scleral bukle rejection was observed in one case. CONCLUSION: ATRD was not associated at posterior vitreous detachment. It was observed in young myopic patients. There is a chronic form of retinal detachment with many tears. Scleral buckle was the surgical treatment of this type of RD with good anatomical prognostic. PMID- 29446817 TI - Depression in Tunisian type 2 diabetic patients: prevalence and association to glycemic control and to treatment compliance. AB - AIM: to study the prevalence of depression in type 2 diabetes and to seek for a relationship between glycemic control and treatment adherence. METHODS: This cross-sectional study was carried out at the outpatient department of the Tunis nutrition institute. A total of 100 diabetic patients followed for Type 2 diabetes were randomly recruited. We used a structured questionnaire to collect patients' socio-demographic, clinical and therapeutic data. The treatment adherence was assessed by using MAS, Glycemic control according to blood glucose and glycated hemoglobin (HbA1c) levels and depression and anxiety by administering a dialectal Arabic validated version of Hospital Anxiety and Depression Scale (HAD). Finaly we also used the modules on mood disorders of the mini international neuropsychiatric interview (MINI). RESULTS: The prevalence of depression in T2DP was 38% according to the HAD scale with severe forms in 18%. The anxiety prevalence was 31%. However, 18% of T2DP had anxious-depressive co morbidity. According to the MINI, 31% of T2DP had a mood disorder. Dysthymia was noted in 14% of cases, an isolated depressive episode in 6%. Depressed T2DP have a poor glycemic control than those no depressed. Macro-angiopathy, irregular followed-up, poor treatment adherence and unbalanced diet were associated with depression. CONCLUSION: The detection of depression related to somatic pathology in particular diabetes, seems essential. As a result, depression treatment may improve the overall prognosis of the associated somatic diseases. PMID- 29446818 TI - Heart involvement in systemic sclerosis. AB - INTRODUCTION: Primary and secondary heart involvement in systemic sclerosis are important mortality predictors. Aim of this study was to investigate by standard echocardiography associated to pulsed-tissue Doppler imaging, six-minute walk test (6MWT) and BNP level cardiac manifestation in 30 patients with ScS and to establish a strategy to detect and to evaluate this complication. METHODS: This was a cross-sectional study conducted over a period of 16 months: a total of 30 consecutive patients with ScS diagnosed as proposed by the American college of Rheumatology and the European League Against Rheumatism 2013 and who were hospitalized in Internal Medicine department of Habib Thameur hospital underwent cardiac assessment. RESULTS: Twenty-nine patients were female, the mean age of diagnosis was 46 years +/- 13,49 [18-71 years]. Echocardiography found left ventricular systolic dysfunction (LVSD) on tissue doppler imaging, in 40% of cases, it was significantly associated with diffuse ScS (p=0,024), with Scl70 anti bodies (p=0,043) and interstitial lung disease (p=0,024). However, the left ventricular diastolic dysfunction (LVDD) was correlated with a high diastolic arterial hypertension (p=0,028), diffuse ScS (0,048), telangiectasia (p=0,029) and pulmonary hypertension (p=0,033). Higher systolic pulmonary arterial pressure (PAPs) (p=0,029) and higher BNP level (p=0,027) were noted in the group of patients with right ventricular systolic dysfunction (RVSD). Patients who had an elevated PAPs had: accelerated pulse (p=0,022), a cough (p=0,024), dyspnea III-IV (p=0,003), shorter six-minute walk distance (p=0,044), greater Borg score (p=0,025) and elevated BNP level (p=0,015). Thus, a positive correlation was found between PAPs and BNP (p=0,004, r=+0,53), a negative correlation was noted between PAPs and ST (p=0,006, r=-0,49). The ROC curve identified a discriminator threshold for ST<11,5cm/s (BNP >=43,5pg/l) and PAPs >35mmHg (BNP >=92pg/l). A discriminator value of the 6MWD (>=294m) was recorded for a PAPs >35mmHg. 2000 3000 salma Conclusion: Left ventricular diastolic impairment was the most frequent echographic abnormality in our study. The BNP level and 6MWT are sensitive and specific in the detection of an elevation of PAPs. PMID- 29446819 TI - Ileoanal J pouch prolapse: a rare complication after restorative coloproctectomy.

AB - BACKGROUND: Sickle cell disease, a common recessively inherited haemoglobin disorder, affects people from sub-Saharan Africa, the Middle East, Mediterranean basin, Indian subcontinent, Caribbean and South America. It is associated with complications and a reduced life expectancy. Phytomedicines (medicine derived from plants in their original state) encompass many of the plant remedies from traditional healers which the populations most affected would encounter. Laboratory research and limited clinical trials have suggested positive effects of phytomedicines both in vivo and in vitro. However, there has been little systematic appraisal of their benefits. This is an update of a Cochrane Review first published in 2004, and updated in 2010, 2013, and 2015. OBJECTIVES: To assess the benefits and risks of phytomedicines in people with sickle cell disease of all types, of any age, in any setting. SEARCH METHODS: We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Haemoglobinopathies Trials Register, the International Standard Randomised Controlled Trial Number Register (ISRCTN), the Allied and Complimentary Medicine Database (AMED), ClinicalTrials.gov and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP).Dates of most recent searches: Cochrane Cystic Fibrosis and Genetic Disorders Haemoglobinopathies Trials Register: 10 April 2017; ISRCTN: 26 July 2017; AMED: 24 August 2017; ClinicalTrials.gov: 02 August 2017; and the WHO ICTRP: 27 July 2017. SELECTION CRITERIA: Randomised or quasi randomised trials with participants of all ages with sickle cell disease, in all settings, comparing the administration of phytomedicines, by any mode to placebo or conventional treatment, including blood transfusion and hydroxyurea. DATA COLLECTION AND ANALYSIS: Both authors independently assessed trial quality and extracted data. MAIN RESULTS: Two trials (182 participants) and two phytomedicines Niprisan(r) (also known as Nicosan(r)) and Ciklavit(r) were included. The Phase IIB (pivotal) trial suggests that Niprisan(r) was effective in reducing episodes of severe painful sickle cell disease crisis over a six month period (low-quality evidence). It did not affect the risk of severe complications or the level of anaemia (low-quality evidence). No serious adverse effects were reported. The single trial of Cajanus cajan (Ciklavit(r)) reported a possible benefit to individuals with painful crises (low-quality evidence), and a possible adverse effect (non-significant) on the level of anaemia (low-quality evidence). AUTHORS' CONCLUSIONS: While Niprisan(r) appeared to be safe and effective in reducing severe painful crises over a six-month follow-up period, further trials are required to assess its role in the management of people with sickle cell disease and the results of its multicentre trials are awaited. Currently no conclusions can be made regarding the efficacy of Ciklavit(r). Based on the published results for Niprisan(r) and in view of the limitations in data collection and analysis of both trials, phytomedicines may have a potential beneficial effect in reducing painful crises in sickle cell disease. This needs to be further validated in future trials. More trials are required on the safety and efficacy of phytomedicines used in managing sickle cell disease. PMID- 29446826 TI - 1,3,6,7-Tetrahydroxy-8-prenylxanthone ameliorates inflammatory responses resulting from the paracrine interaction of adipocytes and macrophages. AB - BACKGROUND AND PURPOSE: Chronic inflammation in adipose tissue is critical in the onset and development of insulin resistance and type 2 diabetes. Macrophage infiltration into adipose tissue and pro-inflammatory polarization play key roles in adipose tissue inflammation. The fruit hull of mangosteen (Garcinia mangostana) is used in traditional medicine to treat various inflammatory diseases. However, its role in regulating adipose tissue inflammation is unexplored. This study was designed to identify xanthones from G. mangostana, which could ameliorate adipose tissue inflammation. EXPERIMENTAL APPROACH: Expressions of inducible NOS, cytokines, chemokines and components of the NF kappaB and MAPKs pathways were evaluated using Western blotting, immunofluorescence, quantitative real-time PCR or ELISA. The migration of macrophages towards adipocytes was tested using Transwell experiments in vitro. A murine model of LPS-induced acute inflammation was used to examine effects of 1,3,6,7-tetrahydroxy-8-prenylxanthone (TPX) on inflammatory responses in adipose tissue in vivo. KEY RESULTS: From a series of xanthones isolated from G. mangostana, TPX was identified as a potent inhibitor of LPS-induced NO production and IL-6 secretion in RAW264.7 macrophages. TPX ameliorated LPS-induced inflammatory responses in RAW264.7 macrophages, and TNF-alpha-mediated inflammation in 3T3-L1 adipocytes, through inhibiting MAPKs and NF-kappaB activation and promoting sirtuin 3 expression. TPX also blocked RAW264.7 macrophages migration towards 3T3-L1 adipocytes in co-cultures. Furthermore, TPX alleviated LPS-induced adipose tissue inflammation in vivo by reducing pro inflammatory cytokines and preventing the pro-inflammatory polarization of macrophages. CONCLUSIONS AND IMPLICATIONS: Taken together, our results indicate that TPX disrupts the inflammatory responses between macrophages and adipocytes, and attenuates adipose tissue inflammation.

AB - BACKGROUND: In order to investigate the effect of ultrasound dielectric pretreatment on the oxidation resistance of vacuum-fried apple chips, apple slices were pretreated at ultrasonic powers of 150, 250 and 400 W for times of 10, 20 and 30 min before vacuum frying. The quality and oxidation resistance of fried apple were evaluated by testing the dielectric properties and comparing the moisture content, oil uptake, color, acid value (AV) and peroxide value (PV) of apple chips. RESULTS: Ultrasonic treatment significantly changed the dielectric properties of apple slices. Moisture and oil contents of apple chips decreased with increasing ultrasonic power and time. During storage, the color retention of fried apple chips processed by ultrasound was improved. AV and PV values of fried apple chips processed by ultrasound were lower, which improved their antioxidant properties. CONCLUSION: The results of the present study indicated that ultrasound dielectric pretreatment improved not only the quality of vacuum-fried apple chips but also their antioxidant properties.

A retrospective clinical study. AB - STUDY QUESTION: To investigate whether sperm recovery is related to clinical features, hormone parameters and testosterone replacement therapy (TRT) in patients with Klinefelter syndrome (KS). SUMMARY ANSWER: This study provides three interesting insights: (i) the probability to retrieve sperm is not related to testicular volume; (ii) TRT does not affect sperm retrieval rate (SRR); and (iii) reduced levels of LH and FSH represent a negative predictor of sperm retrieval in patients with TRT. WHAT IS KNOWN ALREADY: Classical KS shows a karyotype with one extra X chromosome in all of somatic cells and clinical manifestations characterized by hypergonadotropic hypogonadism and infertility. STUDY DESIGN, SIZE AND DURATION: We performed a retrospective cohort study. Data from 111 consecutive KS azoospermic patients undergoing testicular sperm extraction (TESE) were collected from 2005 to 2016. PARTICIPANTS/MATERIALS, SETTING AND METHODS: Data on anthropometric parameters, reproductive hormones and testicular volumes were collected. SRR was related to clinical characteristics and compared between TRT and untreated patients. MAIN RESULTS AND THE ROLE OF CHANCE: A total of 38 patients (34.2%) had successful sperm recovery. The comparison of clinical characteristics did not differ between patients with and without sperm recovery. Sperm retrieval was successful also in subjects with smaller testes. The comparison of SRR in patients with or without TRT was not different (33.3% vs 34.6%). In TRT group, LH and FSH levels were significantly lower in subjects with no sperm retrieval (P values, respectively, <.05 and <.001). LIMITATIONS AND REASONS FOR CAUTION: Well-designed controlled studies are necessary to confirm these data aimed to set the best therapeutic approach for fertility management in hypogonadal patients with nonmosaic KS. WIDER IMPLICATIONS OF THE FINDINGS: Age at TESE, anthropometric measures, testis volume, sex hormones levels and semen parameters are not predictive parameters of SRR. Among TRT patients, reduced gonadotropin is related to failure in sperm retrieval. PMID- 29446829 TI - Injection testosterone and adverse cardiovascular events: A case-crossover analysis. AB - CONTEXT: Exogenous testosterone administration may affect blood clotting, polycythaemia, and may increase atherosclerosis, though any association with cardiovascular events is unclear. While the literature is inconclusive, some studies have suggested testosterone use may increase short-term risk of cardiovascular events and stroke, and injection testosterone may convey higher risks than other dosage forms. OBJECTIVE: We sought to evaluate the short-term cardiovascular risk of receiving injection testosterone. DESIGN: We conducted a case-crossover analysis comparing injection testosterone exposure in the 7 days prior to an outcome event to referent windows in the past to estimate the acute association of cardiovascular outcomes with the receipt of testosterone injections. PATIENTS: We identified adult male testosterone users hospitalized with myocardial infarction (MI), stroke or a composite of MI, stroke or unstable angina in US commercial claims (2000-2013) or Medicare (2007-2010) databases. MEASUREMENTS: We identified testosterone use for the patients from pharmacy dispensing claims or in-office procedure codes in the insurance billing data. RESULTS: We identified 2898 commercially insured men with events and recent testosterone use, and 339 from Medicare. Injected testosterone was associated with an increased risk of adverse events (composite outcome of myocardial infarction, stroke or unstable angina) in the immediate postinjection period for the older, Medicare population only: commercial insurance, odds ratios (OR) = 0.98 (95% confidence intervals [CI]: 0.86-1.12); Medicare, OR = 1.45 (1.07, 1.98). This association was either greatly attenuated or not present when evaluating receipt of any testosterone dosage forms (injection, gel, patch, implant): commercial insurance, OR = 1.01 (0.92, 1.11); Medicare, OR = 1.26 (95% CI: 0.98-1.63). CONCLUSIONS: Testosterone injections were uniquely associated with short-term risk of acute cardio- and cerebrovascular events in older adult men following injection receipt. PMID- 29446830 TI - Prior ingestion of exogenous ketone monoester attenuates the glycaemic response to an oral glucose tolerance test in healthy young individuals. AB - KEY POINTS: The recent development of exogenous ketone supplements allows direct testing of the metabolic effects of elevated blood ketones without the confounding influence of widespread changes experienced with ketogenic diets or prolonged fasting. In the present study, we determined the effect of (R)-3 hydroxybutyl (R)-3-hydroxybutyrate ketone monoester on the glycaemic response and insulin sensitivity index during a 2 h oral glucose tolerance test (OGTT) in humans. The results obtained show that consuming a ketone monoester supplement 30 min prior to an OGTT reduced the glycaemic response and markers of insulin sensitivity without affecting insulin secretion. The findings of the present study provides evidence that ketone supplements could have therapeutic potential for future application as a glucose-lowering nutritional supplement. ABSTRACT: The main objectives of the present study were: (i) to determine whether acute ingestion of ketone monoester (Kme ); (R)-3-hydroxybutyl (R)-3-hydroxybutyrate impacts plasma glucose levels during a standardized oral glucose tolerance test (OGTT) and (ii) to compare changes in insulin concentrations and estimates of insulin sensitivity after acute Kme supplementation. Twenty healthy participants (n = 10 males/females) aged between 18 and 35 years took part in a randomized cross-over study. After an overnight fast, participants consumed a Kme supplement (DeltaG(r); TDeltaS Ltd, UK, Oxford, UK; 0.45 ml kg-1 body weight) or placebo (water) 30 min before completing a 75 g OGTT. Blood samples were collected every 15-30 min over 2.5 h. The participants and study personnel performing the laboratory analyses were blinded to the study condition. Kme acutely raised blood d-beta-hydroxybutyrate (beta-OHB) to 3.2 +/- 0.6 mm within 30 min with levels remaining elevated throughout the entire OGTT. Compared to placebo, Kme significantly decreased the glucose area under the curve (AUC; -16%, P = 0.001), non-esterified fatty acid AUC (-44%, P < 0.001) and C-peptide incremental AUC (P = 0.005), at the same time as improving oral glucose insulin sensitivity index by ~11% (P = 0.001). In conclusion, a Kme supplement that acutely increased beta-OHB levels up to ~3 mm attenuated the glycaemic response to an OGTT in healthy humans. The reduction in glycaemic response did not appear to be driven by an increase in insulin secretion, although it was accompanied by improved markers of insulin sensitivity. These results suggest that ketone monoester supplements could have therapeutic potential in the management and prevention of metabolic diseases. PMID- 29446831 TI - The importance of key floral bioactive compounds to honey bees for the detection and attraction of hybrid vegetable crops and increased seed yield. AB - BACKGROUND: Crop breeding programmes generally select for traits for improved yield and human consumption preferences. Yet, they often overlook one fundamental trait essential for insect-pollinated crops: pollinator attraction. This is even more critical for hybrid plants that rely on cross-pollination between the male fertile line and the male-sterile line to set seeds. This study investigated the role of floral odours for honey bee pollination that could explain the poor seed yield in hybrid crops. RESULTS: The key floral bioactive compounds that honey bees detect were identified for three vegetable hybrid crops. It was found that 30% of the variation in bioactive compound quantities was explained by variety. Differences in quantities of the bioactive compounds triggered different degrees of olfactory response and were also associated with varied appetitive response. Correlating the abundance of each bioactive compound with seed yield, it was found that aldehydes such as nonanal and decanal can have a strong negative influence on seed yield with increasing quantity. CONCLUSION: Using these methodologies to identify relevant bioactive compounds associated with honey bee pollination, plant breeding programmes should also consider selecting for floral traits attractive to honey bees to improve crop pollination for enhanced seed yield.

AB - CONTEXT: Bronchopulmonary neuroendocrine tumours (bpNETs) and thymic carcinoid (ThC) are features of multiple endocrine neoplasia type 1 (MEN 1), and surveillance guidelines recommend periodic thoracic imaging. The optimal thoracic imaging modality and screening frequency remain uncertain as does the prognosis of small lung nodules when identified. OBJECTIVES: To evaluate fluorodeoxyglucose positron emission tomography/computed tomography (18 F-FDG PET/CT) for identification and prognostic assessment of thoracic lesions in MEN 1. DESIGN: Retrospective observational study. SETTING AND PARTICIPANTS: Fifty consecutive MEN 1 patients undergoing screening with 18 F-FDG PET/CT at a tertiary referral hospital between July 2011 and December 2016. INTERVENTIONS: 18 F-FDG PET/CT. OUTCOME MEASURES: Pulmonary and thymic lesion prevalence, size, functional characteristics and behaviour. RESULTS: Thirteen patients (26.0%) exhibited pulmonary nodules with multiple nodules identified in nine (18.0%). An asymptomatic 31 mm FDG-avid ThC was identified in one patient (2%). Of the 13 patients with pulmonary nodules, four (8.0%) exhibited 13 FDG-avid nodules (mean size 10.1 +/- 9.1 mm), and nine (18.0%) demonstrated 26 FDG nonavid nodules (mean size 6.9 +/- 5.8 mm). All FDG-avid lesions increased in size vs 11 (42.3%) FDG nonavid lesions (P = .0004). For FDG-avid and nonavid nodules, the median doubling time was 24.2 months (IQR 11.4-40.7) and 48.6 months (IQR 37.0-72.2), respectively. Nodule resection was undertaken in two patients, typical bronchial carcinoid diagnosed in one (FDG nonavid) and metastatic renal cell carcinoma in the second (FDG avid). CONCLUSION: Thoracic imaging with 18 F-FDG PET/CT effectively identifies pulmonary nodules and ThC. FDG-avid pulmonary lesions are significantly more likely to progress than nonavid lesions. PMID- 29446833 TI - Body fat content, fat distribution and adipocytokine production and their correlation with fertility markers in young adult men and women conceived by intracytoplasmic sperm injection (ICSI). AB - OBJECTIVE: Differences in body fat content during childhood and adolescence have been described in offspring conceived by in vitro fertilisation (IVF) and intracytoplasmic sperm injection (ICSI). However, data on body fat and its distribution as well as on adipocytokine production in young adults conceived by ICSI are nonexistent. We investigated if young adult men and women conceived by ICSI have a normal body fat patterning and adipocytokine production. DESIGN: Cohort study. PATIENTS: One hundred twenty-seven young adults conceived by ICSI and 138 peers born after spontaneous conception. MEASUREMENTS: Anthropometric parameters (skinfold thickness, hip and waist circumferences), dual X-ray absorptiometry (whole body and regional) measurements and adipocytokine levels (leptin and adiponectin) were analysed in relation to fertility markers (serum anti-Mullerian hormone (AMH) and inhibin B). RESULTS: While at age 18 years, a normal body fat distribution and normal leptin and adiponectin production was found in both male and female ICSI offspring, young men conceived by ICSI had a higher peripheral fat deposition in comparison with spontaneously conceived peers. No correlation between AMH and inhibin B with leptin or adiponectin was observed. CONCLUSION: While men conceived by ICSI, but not women, had a higher peripheral fat deposition, body fat distribution as well as mean levels of adipocytokines were not affected by the mode of conception. PMID- 29446834 TI - The HDL anti-inflammatory function is impaired in the context of low-normal free thyroxine in diabetic and nondiabetic individuals. PMID- 29446835 TI - Eudicots from severely phosphorus-impoverished environments preferentially allocate phosphorus to their mesophyll. AB - Plants allocate nutrients to specific leaf cell types, with commelinoid monocots preferentially allocating phosphorus (P) to the mesophyll and calcium (Ca) to the epidermis, whereas the opposite is thought to occur in eudicots. However, Proteaceae from severely P-impoverished habitats present the same P-allocation pattern as monocots. This raises the question of whether preferential P allocation to mesophyll cells is a phylogenetically conserved trait, exclusive to commelinoid monocots and a few Proteaceae, or a trait that has evolved multiple times to allow plants to cope with very low soil P availability. We analysed the P-allocation patterns of 16 species from 10 genera, eight families and six orders within three major clades of eudicots across different P-impoverished environments in Australia and Brazil, using elemental X-ray mapping to quantitatively determine leaf cell-specific nutrient concentrations. Many of the analysed species showed P-allocation patterns that differed substantially from that expected for eudicots. Instead, P-allocation patterns were strongly associated with the P availability in the natural habitat of the species, suggesting a convergent evolution of P-allocation patterns at the cellular level, with P limitation as selective pressure and without a consistent P-allocation pattern within eudicots. Here, we show that most eudicots from severely P impoverished environments preferentially allocated P to their mesophyll. We surmise that this preferential P allocation to photosynthetically active cells might contribute to the very high photosynthetic P-use efficiency of species adapted to P-impoverished habitats. PMID- 29446836 TI - Adverse pregnancy outcomes and future maternal cardiovascular disease. AB - Cardiovascular disease (CVD) remains the leading cause of death in women. Although traditional risk factors increase later-life CVD, pregnancy-associated complications additionally influence future CVD risk in women. Recent guidelines for the prevention of CVD in women have added adverse pregnancy outcomes as major CVD risk factors. Studies have shown that women with a history of preeclampsia, gestational diabetes, preterm delivery, and delivery of a small-for-gestational age infant have an increased risk of developing cardiometabolic risk factors and subsequent CVD. A history of multiple adverse pregnancy outcomes further increases this risk. It has been suggested that these pregnancy complications may unmask preexisting elevated CVD risk; however, whether the pathophysiologic changes underlying these conditions directly result in long-term cardiovascular damage is unclear. The purpose of this review was to highlight the associations between adverse pregnancy outcomes and future CVD, and to emphasize the importance of considering pregnancy history in assessing a woman's CVD risk. Targeted efforts to initiate screening and risk-reduction strategies in women with prior history of pregnancy complications, particularly lifestyle modification, may help decrease the burden of CVD in women. PMID- 29446837 TI - 25-OH-vitamin D, parathyroid hormone, and calcium serum levels in captive common marmosets (Callithrix jacchus): Reference values and effect of age, sex, season, and closure of long bone epiphyses. AB - BACKGROUND: To date, reference values for 25-OH-vitamin D, parathyroid hormone (PTH), and calcium in serum of common marmosets (Callithrix jacchus) based on a large sample size are not available. METHODS: Serum reference values for these parameters were determined and correlated with sex, age, season of sampling, and time of long bone epiphyseal closure in captive-housed marmosets. RESULTS AND CONCLUSIONS: The 90% reference range for serum 25-OH-vitamin D is 47.40-370.4 nmol/L, for PTH 2.10-30.51 pmol/L, and for calcium 2.08-2.63 mmol/L. Lower levels of vitamin D were measured in fall compared with the other seasons. Levels of PTH were higher in males than in females, and calcium levels were lower in younger animals compared with older marmosets. No other effects of age, sex, season, or timing of growth plate closure were found. PMID- 29446838 TI - The Effect of Pyrazolyl Substituents on the Photophysical and Photochemical Properties of Pyrazine Derivatives. AB - The reaction of 2,5-dibromopyrazine with N-Lithium pyrazolate in a 1:2 ratio leads to a mixture of 2-bromo-5-(1H-pyrazol-1-yl)pyrazine (I) and 2,5-di(1H pyrazol-1-yl)pyrazine (II). The structures of I and II are highly planar. Two absorption bands can be observed for the compounds in the UV-Vis region, having epsilon in the order of 104 m-1 cm-1 . TD-DFT computed results support the nature of the lower energy absorptions as pipyrazine ->pi*pyrazine transitions, including an additional intraligand charge transfer transition for I (pipyrazol >pi*pyrazine ). Upon excitation at 280 or 320 nm, the emission of both compounds is almost not affected by solvent polarity or oxygen presence, showing two bands for I and one for II in the 350-450 nm region. Emission of II follows a mono exponential decay, while I decays following a bi-exponential law, hypothesized from pipyrazine ->pi*pyrazine and pipyrazol ->pi*pyrazine transitions. Photodegradation of I and II follows a first-order kinetic with constants of 1.18 * 10-2 min-1 and 0.13 * 10-2 min-1 , respectively. Results suggest that photodegradation of I starts with the loose of bromide followed by intermolecular pyrazolyl subtraction and ring opening. This path is not available for II, which is reflected in its enhanced photostability. PMID- 29446839 TI - Siphonaxanthin, a Carotenoid From Green Algae, Inhibits Lipogenesis in Hepatocytes via the Suppression of Liver X Receptor alpha Activity. AB - Nonalcoholic fatty liver disease (NAFLD) has shown an increasing morbidity in recent years. Here, we demonstrated that siphonaxanthin (SPX), a rare marine carotenoid, exhibits a strong inhibitory effect on aggravated hepatic lipogenesis in vitro and would be a promising candidate in the prevention and alleviation of NAFLD in the future. In this study, we conducted a preliminary assessment of the effect of SPX on hepatic lipogenesis by using the HepG2 cell line, derived from human liver cancer, as a model of the liver. SPX significantly suppressed the excess accumulation of triacylglycerol induced by liver X receptor alpha (LXRalpha) agonist by downregulating a nuclear transcription factor named sterol regulatory element-binding protein-1c and a set of related genes. Moreover, fatty acid translocase (CD36) and fatty acid-binding protein-1, which regulates fatty acid uptake, also exhibited significant decrease in transcriptional levels. Furthermore, we found that SPX blocked LXRalpha activation and would be a promising candidate for antagonist of LXRalpha. PMID- 29446840 TI - Uncontrolled blood pressure affects atrial remodeling and adverse clinical outcome in paroxysmal atrial fibrillation. AB - BACKGROUND: To investigate the impact of uncontrolled blood pressure (BP) on left atrial (LA) remodeling and clinical outcome after pulmonary vein isolation (PVI) in paroxysmal atrial fibrillation (AF). METHODS: One hundred and one symptomatic paroxysmal AF patients (85 males, 62.2 +/- 8.4-year-old) who underwent successful PVI were classified as follows: group 1 (n = 46), no hypertension (HTN); group 2 (n = 36), HTN with controlled BP; and group 3 (n = 19), HTN with uncontrolled BP. Uncontrolled BP was defined as BP > 140/90 mm Hg. LA dimension was measured by echocardiography before and 6 months after PVI. LA wall thickness along the ablation line was measured using computed tomography prior to PVI. Cox regression analysis was performed for the prediction of recurrence. RESULTS: LA wall thickness in groups 2 and 3 was greater than that of group 1, except for the anterior right superior pulmonary vein (PV) and posterior left inferior PV. Kaplan-Meier analysis revealed a significantly higher recurrence in group 3 (52.6%). LA dimension only increased in group 3 (38.2 +/- 5.6 mm to 41.3 +/- 6.2 mm, P = 0.022). At the second procedure, all group 3 recurrent patients showed substrate degradation (low voltage area and/or dense scar formation) and required substrate modification. Uncontrolled BP was an independent risk factor for recurrence (hazard ratio: 2.350, P = 0.033). CONCLUSIONS: HTN induced heterogeneous LA hypertrophy regardless of whether HTN was controlled. Uncontrolled BP promoted atrial remodeling, and is therefore a strong predictor for recurrence of AF after PVI. PMID- 29446841 TI - The connection between the breast and heart in a woman: Breast cancer and cardiovascular disease. AB - Cardiovascular disease remains the leading cause of death in women in the United States and is a major public health issue for all women, but it is of increasing concern to breast cancer survivors. Advancements in early detection and breast cancer therapy have resulted in over 90% of women surviving 5 years past their diagnosis of breast cancer. Nonetheless, with increased survivorship from breast cancer, there has been an increase in cardiovascular disease in these women. The consequences of the treatments for breast cancer may increase the risk for cardiovascular disease. Additionally, there is an overlap of risk factors common to both breast cancer and cardiovascular disease. The increased risk of cardiovascular disease in women who survive breast cancer must be recognized, with a focus on the prevention and early detection of cardiovascular disease. PMID- 29446842 TI - Epidemiology and Risk Factors for Outpatient-Acquired Catheter-Related Bloodstream Infections in Children Receiving Home Parenteral Nutrition. AB - BACKGROUND: Few studies have examined the epidemiology and risk factors for the development of outpatient-acquired catheter-related bloodstream infections (CRBSIs) in children receiving home parenteral nutrition. This study aimed to (1) characterize the incidence, clinical presentation, and epidemiology of CRBSIs and (2) identify risk factors for CRBSIs in children receiving home parenteral nutrition. METHODS: A longitudinal database approved by our Institutional Review Board was created to prospectively track CRBSIs in the UCLA pediatric population from January to December 2012. Eligible patients included those < 18 years old receiving home parenteral nutrition. RESULTS: Thirty of 60 patients (50%) were diagnosed with 66 CRBSIs, for an overall CRBSI rate of 3.6 per 1000 catheter days. Of the CRBSIs, 73% were due to single microorganisms and 27% were polymicrobial. There was a significant difference in median (range) time for blood cultures to turn positive depending on type of CRBSIs (p = 0.03), with polymicrobial infections detected at 13.4 (8.7-24.3) hours, gram-negative infections at 16.5 (9-30.8) hours, and gram-positive infections at 18.9 (8.4 37.1) hours. The most common presenting symptom was fever (82%), followed by gastrointestinal symptoms (42%) and chills (29%). The only significant multivariate risk factor for CRBSIs was presence of a feeding tube (2.3-fold increase in CRBSI risk, p = 0.04). DISCUSSION: Outpatient-acquired CRBSIs are common in children receiving home parenteral nutrition. CRBSIs typically present with fever, but are also associated with gastrointestinal and/or respiratory symptoms. The presence of feeding tubes may predispose children on home parenteral nutrition to developing CRBSIs.

PMID- 29446845 TI - Simultaneous determination of 10 kinds of biogenic amines in rat plasma using high-performance liquid chromatography coupled with fluorescence detection. AB - We describe a simple, rapid, selective and sensitive HPLC method coupled with fluorescence detection for simultaneous determination of 10 kinds of biogenic amines (BAs: tryptamine, 2-phenethylamine, putrescine, cadaverine, histamine, 5 hydroxytryptamine, tyramine, spermidine, dopamine and spermine). BAs and IS were derivated with dansyl chloride. Fluorescence detection (lambdaex /lambdaem = 340/510 nm) was used. A satisfactory result for method validation was obtained. The assay was shown to be linear over the ranges 0.005-1.0 MUg/mL for tryptamine, 2-phenethylamine and spermidine, 0.025-1.0 MUg/mL for putrescine, 0.001-1.0 MUg/mL for cadaverine, 0.25-20 MUg/mL for histamine, 0.25-10 MUg/mL for 5 hydroxytryptamine and dopamine, and 0.01-1.0 MUg/mL for tyramine and spermine. The limits of detection and the limits of quantification were 0.3-75.0 ng/mL and 1.0-250.0 ng/mL, respectively. Relative standard deviations were <=5.14% for intra-day and <=6.58% for inter-day precision. The recoveries of BAs ranged from 79.11 to 114.26% after spiking standard solutions of BAs into a sample at three levels. Seven kinds of BAs were found in rat plasma, and the mean values of tryptamine, 2-phenethylamine, putrescine, cadaverine, histamine, spermidine and spermine determined were 52.72 +/- 7.34, 11.45 +/- 1.56, 162.56 +/- 6.26, 312.75 +/- 18.11, 1306.50 +/- 116.16, 273.89 +/- 26.41 and 41.51 +/- 2.07 ng/mL, respectively. PMID- 29446846 TI - Histological immune response patterns in sentinel lymph nodes involved by metastatic melanoma and prognostic significance. AB - BACKGROUND: To further characterize the micromorphometric immunological pattern to metastatic melanoma in sentinel lymph node (SLN) biopsies and completion lymph node (CLN) dissections and their relation to 5-year overall survival (OS). METHODS: Retrospective cohort of 49 patients from 1996 to 2005 with a positive SLN who underwent CLN dissection (CLD) was studied. Micromorphometric characteristics included follicular center count (FCC)/profile, sinus histiocytosis, metastatic size, tumor infiltrating lymphocytes (intranodal), paracortical dendritic cells, germinal center reaction and morphology. Comparison of Kaplan-Meier survival curves used the exact log-rank statistic. RESULTS: In the high-FCC (n = 5-51) vs the low-FCC (n < 5) lymph nodes, a delayed separation occurred at 3 years, with 5-year OS rates being 73% vs 54% in the high- and low FCC groups, respectively. Improved survival up to 3 years was also noted in CLDs that showed a higher FCC when compared to the prior SLN. Patients with metastatic deposits >2 mm had significantly lower 5-year survival (both <.001). CONCLUSIONS: Nodal micromorphometric features (ie, FCC) are probably related to host immune response to metastasis. Quantitative evaluation of lymphoid follicular centers could provide valuable prognostic information to help to stratify patients. PMID- 29446847 TI - Lipidomic Analysis: From Archaea to Mammals. AB - Lipids are among the most important organic compounds found in all living cells, from primitive archaebacteria to flowering plants or mammalian cells. They form part of cell walls and constitute cell storage material. Their biosynthesis and metabolism play key roles in faraway topics such as biofuel production (third generation biofuels produced by microorganisms, e.g. algae) and human diseases such as adrenoleukodystrophy, Zellweger syndrome, or Refsum disease. Current lipidomic analysis requires fast and accurate processing of samples and especially their characterization. Because the number of possible lipids and, more specifically, molecular species of lipids is of the order of hundreds to thousands, it is necessary to process huge amounts of data in a short time. There are two basic approaches to lipidomic analysis: shotgun and liquid chromatography mass spectometry. Both methods have their pros and cons. This review deals with lipidomics not according to the type of ionization or the lipid classes analyzed but according to the types of samples (organisms) under study. Thus, it is divided into lipidomic analysis of archaebacteria, bacteria, yeast, fungi, algae, plants, and animals. PMID- 29446848 TI - Methodological issues in assessing the association between periodontitis and caries among adolescents. AB - OBJECTIVES: We aimed to investigate the association between dental caries and periodontitis among adolescents participating in a case-control study of periodontitis. In addition, we compared 2 analytical approaches to estimate the association: conventional regression and structural equation modelling (SEM). METHODS: Along with periodontal recordings, data were obtained on caries, just as subgingival plaque samples were collected. Sociodemographic information was collected with a questionnaire. We used factor analyses to express the many correlated clinical periodontal dimensions in a smaller number of factors. The association between caries (counts of enamel and dentin lesions, or dentin lesions only) and periodontitis was tested using negative binomial regression with robust variance (conventional regression) and weighted least squares (SEM) estimation. RESULTS: Factor analysis revealed 2 different latent periodontal variables: "extent" and "severity" of periodontitis. Using conventional regression, the "extent" of periodontitis was positively associated with higher counts of dentin caries lesions, even after adjustments for maternal education and subgingival microbial composition (rate ratio 1.34; 95% CI 1.07-1.68). The "severity" of periodontitis was associated with lower counts of enamel and dentin caries lesions (rate ratio 0.85 95% CI 0.77-0.92). The SEM revealed a positive association between periodontitis "extent" and number of dentin caries lesions (coefficient 0.29; P < .0001). The "severity" of periodontitis was negatively associated with enamel and dentin caries (coefficient -0.44; P < .0001). CONCLUSIONS: We found an association between caries and periodontitis among adolescents. The "severity" of periodontitis was negatively associated with enamel/dentin caries, whereas the "extent" of periodontitis was positively associated with dentin caries irrespective of the analytical approach employed. PMID- 29446849 TI - Anxiety and anger of homeless people coping with dental care. AB - OBJECTIVES: To reveal and describe from open-ended interviews how homeless people in Vancouver interpret, appraise and cope with dental care. METHODS: Audio recorded interviews with 25 homeless people (18 men and 7 women; age range: 25-64 years), purposefully selected for a range of experiences, were transcribed and analysed inductively. The process of interpretive description drawing from the Behavioral Model for Vulnerable Populations and Lazarus's Theory of Emotions identified how participants appraised and coped with dental care. RESULTS: Four dominant themes emerged: barriers to care; service use; opinions on dental health; and improving dental services. Participants were anxious about the cost of dentistry and fearful of dentists. They got emergency dental care with difficulty, usually in hospital emergency departments although mostly they preferred self-treatment. They acknowledged the importance of dental health but felt stigmatized by their homelessness and visibly unhealthy mouths. They wanted accessible dental services with financial assistance from government, more widespread information about community dental clinics, and, notably among the Indigenous participants, less humiliating discrimination from dentists. CONCLUSIONS: Homeless people have difficulty coping with dental care. They believe that dentistry is frightening, humiliating and expensive, and governments are neither sympathetic to their disability nor willing to provide helpful information about community dental clinics or sufficient dental benefits for their needs. PMID- 29446850 TI - Superficial acral fibromyxoma in the heel with new vascular features on dermoscopy. AB - Superficial acral fibromyxoma (SAFM) is an uncommon mesenchymal soft tissue tumor with a predilection for the acral extremites and nail bed involvement. SAFM is diagnosed with clinicopathological and immunohistochemical examination. Awareness of this rare tumor is important because of amounts of benign and malignant neoplasms. We report a case of SAFM in a rare localization in the heel with a new finding on dermoscopy. PMID- 29446851 TI - Non-commercial vs. commercial clinical trials: a retrospective study of the applications submitted to a research ethics committee. AB - There are many difficulties in undertaking independent clinical research without support from the pharmaceutical industry. In this retrospective observational study, some design characteristics, the clinical trial public register and the publication rate of noncommercial clinical trials were compared to those of commercial clinical trials. A total of 809 applications of drug-evaluation clinical trials were submitted from May 2004 to May 2009 to the research ethics committee of a tertiary hospital, and 16.3% of trials were noncommercial. They were mainly phase IV, multicentre national, and unmasked controlled trials, compared to the commercial trials that were mainly phase II or III, multicentre international, and double-blind masked trials. The commercial trials were registered and published more often than noncommercial trials. More funding for noncommercial research is still needed. The results of the research, commercial or noncommercial, should be disseminated in order not to compromise either its scientific or its social value. PMID- 29446852 TI - Isolation of Crithidia spp. from lesions of immunocompetent patients with suspected cutaneous leishmaniasis in Iran. AB - OBJECTIVE: Leishmania major has been considered as the main etiological agent of cutaneous leishmaniasis in Iran. However, there are recent reports about existence of Crithidia spp in cutaneous lesions in southern Iran. Therefore, this study was designed to decipher some morphological, biological, and molecular aspects of this phenomenon. METHODS: Clinical isolates were obtained from 167 patients with cutaneous ulcers. A set of specific primers based on GAPDH (Glyceraldehyde-3-Phosphate Dehydrogenase) gene were used to distinguish between Crithidia and Leishmania genera. For molecular analysis, Pulsed Field Gel Electrophoresis and Mi-Seq Illumina platform were applied. Then, morphological analysis and some biological features (including potential growth at 37 degrees C and the ability of infecting mammalian macrophages) were studied. RESULTS: In 92.8% of clinical cases L. major was the only causative microorganism isolated, in 5.4% of cases co-infection of L. major and Crithidia spp. was identified, and in 1.8% of lesions only Crithidia spp. were found. CONCLUSION: We isolated Crithidia spp. from clinical samples of patients suspected of cutaneous leishmaniasis in Iran, indicating that Crithidia spp. are capable of surviving at human body temperature and infecting macrophage cells. This raises questions on the influence of this phenomenon on pathogenicity, therapeutic outcome, and disease control strategies. This article is protected by copyright. All rights reserved.

AB - Abrogating tumor angiogenesis by inhibiting vascular endothelial growth factor receptor-2 (VEGFR2) has been established as a therapeutic strategy for treating cancer. However, because of their low selectivity, most small molecule inhibitors of VEGFR2 tyrosine kinase show unexpected adverse effects and limited anticancer efficacy. In the present study, we detailed the pharmacological properties of anlotinib, a highly potent and selective VEGFR2 inhibitor, in preclinical models. Anlotinib occupied the ATP-binding pocket of VEGFR2 tyrosine kinase and showed high selectivity and inhibitory potency (IC50 <1 nmol/L) for VEGFR2 relative to other tyrosine kinases. Concordant with this activity, anlotinib inhibited VEGF induced signaling and cell proliferation in HUVEC with picomolar IC50 values. However, micromolar concentrations of anlotinib were required to inhibit tumor cell proliferation directly in vitro. Anlotinib significantly inhibited HUVEC migration and tube formation; it also inhibited microvessel growth from explants of rat aorta in vitro and decreased vascular density in tumor tissue in vivo. Compared with the well-known tyrosine kinase inhibitor sunitinib, once-daily oral dose of anlotinib showed broader and stronger in vivo antitumor efficacy and, in some models, caused tumor regression in nude mice. Collectively, these results indicate that anlotinib is a well-tolerated, orally active VEGFR2 inhibitor that targets angiogenesis in tumor growth, and support ongoing clinical evaluation of anlotinib for a variety of malignancies. PMID- 29446854 TI - Overexpression of interleukin-35 in intrahepatic cholangiocarcinoma is a prognostic indicator after curative resection. AB - Interleukin-35 (IL-35) is implicated in tumorigenesis, but its exact impact on intrahepatic cholangiocarcinoma (ICC) is not clear. The aim of the present study was to explore the specific effect of IL-35 on patient prognosis. Additionally, we formulated an effective prognostic nomogram for ICC patients after curative resection. Immunohistochemistry was applied to explore IL-35 expression as well as IL-35 receptor (IL-35R) in 102 ICC patients. Results showed that IL-35 was highly expressed in ICC tumor tissues and was positively associated with lymph node metastasis (LNM), TNM stage and vascular invasion and was an independent prognostic factor for patients' overall survival (OS) and recurrence-free survival (RFS). High expression of IL-35R (gp130 and IL-12Rbeta2) was also observed in ICC cancer tissues, but only gp130 was an independent prognostic factor for OS and RFS and was indispensable in IL-35-mediated ICC clinical prognosis. The nomogram comprising carcinoembryonic antigen, LNM, IL-35 and gp130 expression achieved better predictive accuracy compared with TNM stage for OS. Our data support that high IL-35 expression correlates with ICC aggressiveness and emerges as a valuable biomarker for evaluating ICC progression and prognosis in clinical work. PMID- 29446856 TI - Thyroid carcinoma producing beta-human chorionic gonadotropin shows different clinical behavior. AB - Columnar cell variant of papillary thyroid carcinoma (CCV-PTC) is an unusual neoplasm, the clinical behavior of which mainly depends on the encapsulation or infiltration. Patients with extensive extrathyroidal extension usually have an aggressive biological behavior. This study confirmed that beta-human chorionic gonadotropin (beta-hCG) secreting invasive CCV-PTC has good prognosis comparing with a cohort of follicular cell differentiated thyroid carcinoma. On the contrary, positive immunoreaction with beta-hCG was proved in three anaplastic thyroid carcinoma patients showing aggressive clinical courses. The clinicopathologic characteristics of CCV-PTC and the paraneoplastic syndromes in follicular cell differentiated thyroid carcinoma were further summarized using literature review.

AB - BACKGROUND: Pediatric long-term care facilities (pLTCF) serve a complicated and resource-intensive patient population with high usage of nutrition support. However, the relationship between nutrition support and outcomes among pLTCF residents is not well understood. We described this relationship in three metropolitan New York pLTCF and a subsample of infants from one of these facilities with a feeding disorders unit. METHODS: In this prospective cohort study, we used logistic regression to assess relationships between enteral nutrition (EN), and acute respiratory infections (ARI) among residents (n = 720, 50% male, mean age = 5.5 years, mean number comorbidities = 2.1) and infant subsample (<1 year, n = 208, 50% male, mean number comorbidities = 2.0). We tested these associations in multivariable models controlling for numbers of comorbidities and infections. RESULTS: Many residents received nutrition via percutaneous (59%) or nasogastric (15%) feeding tubes. In univariate analyses, residents receiving EN had more comorbidities. In multivariable analyses, EN was associated with ARI (incidence rate ratio = 1.65, p < .001). Among infants in the specialized unit, greater risk of ARI was associated only with percutaneous (incidence rate ratio = 1.94, p < .01) feeding. EN was associated with lower odds of being discharged home (OR = 0.45, p < .01). CONCLUSION: The prevalence of EN, complexity of cases, and necessity of long-term EN make nutrition support important in pLTCFs. Differences in EN types and adverse outcomes in the infant subsample suggest different care is necessary for this subpopulation. Results provide context for improving quality of care and clinician/caregiver education for this population. PMID- 29446857 TI - Infectious risk of biological drugs vs. traditional systemic treatments in moderate-to-severe psoriasis: a cohort analysis in the French insurance database. AB - The aim of this study was to compare the infectious risk between a group of psoriasis patients treated by biological drugs (BD) and a group treated by traditional systemic treatments (TST). We built a retrospective observational cohort study from the French health insurance database in the Midi-Pyrenees area (2.9 million inhabitants, southwest of France) using data from 01/01/2010 to 12/31/2013. We compared the infectious risk between 'exposed' patients treated with BD (adalimumab, etanercept, infliximab, or ustekinumab) and 'unexposed' patients treated by TST (phototherapy, acitretin, methotrexate, or cyclosporine). We realized a survival analysis on the first infectious event, defined as an anti infective drug delivery or a hospital diagnosis of infection. We selected 101 'exposed' and 788 'unexposed' patients. In our multivariate Cox model, 'exposure' did not seem to decrease the time frame of the first infectious event compared with 'nonexposure' (HR = 0.94, P = 0.62). Among all treatment, the safest seemed to be ustekinumab while the least safe was etanercept. We found factors statistically associated with the risk of infection: gender (female vs. male), economic deprivation, chronic hepatitis B or C, history of cancer, at least one infectious event, and the number of different drugs during the 6-month period before the study. We did not find any difference of infective risk between the BD and the TST. This result enhances the recent PSONET registries conclusions. PMID- 29446858 TI - Enteral Nutrition for Pediatric Crohn's Disease: An Underutilized Therapy. AB - Enteral nutrition (EN) for the treatment of Crohn's disease (CD) involves administration of a liquid nutrition product, administered orally or through tube feeding, while excluding typical dietary components. It is a safe and effective, but largely underused, therapy in the United States as a treatment for CD. EN is a particularly attractive option for pediatric CD as it avoids side effects of corticosteroids, improves growth, and may have a higher likelihood of achieving mucosal healing than some traditional medications. However, there are multiple real and perceived barriers to its use among providers. A comprehensive approach to addressing these barriers to EN may result in its increased use. This paper reviews the literature on the efficacy of EN, methods of utilization, and potential barriers and solutions to those barriers. PMID- 29446859 TI - Dicyanamide Salts that Adopt Smectic, Columnar, or Bicontinuous Cubic Liquid Crystalline Mesophases. AB - Although dicyanamide (i.e., [N(CN)2 ]- ) has been commonly used to obtain low viscosity, halogen-free, room-temperature ionic liquids, liquid-crystalline salts containing such anions have remained virtually unexplored. Here we report a series of amphiphilic dicyanamide salts that, depending on their structures and compositions, adopt smectic, columnar, or bicontinuous cubic thermotropic liquid crystalline mesophases, even at room temperature in some cases. Their thermal properties were explored by polarized light optical microscopy, differential scanning calorimetry, thermogravimetric analysis (including evolved gas analysis), and variable-temperature synchrotron X-ray diffraction. Comparison of the thermal phase characteristics of these new liquid-crystalline salts featuring "V-shaped" [N(CN)2 ]- anions with those of structural analogues containing [SCN]- , [BF4 ]- , [PF6 ]- , or [CF3 SO3 ]- anions indicated that not only the size of the counterion but also its shape should be considered in the development of mesomorphic salts. Collectively, these discoveries may be expected to facilitate the design of thermotropic ionic liquid crystals that form inverted-type bicontinuous cubic and other sophisticated liquid-crystalline phases. PMID- 29446860 TI - Development of a clinical prediction rule for tuberculous meningitis in adults in Lima, Peru. AB - OBJECTIVES: Diagnosis of tuberculous meningitis (TM) is a challenge in countries with a high burden of the disease and constrained resources and clinical prediction rules (CPRs) could be of assistance. We aimed at developing a CPR for diagnosis of TM in a Latin American setting with high tuberculosis incidence and a concentrated HIV epidemic. METHODS: We enrolled adult patients with clinical suspicion of TM attending two hospitals in Lima, Peru. We obtained information on potential anamnestic, clinical and laboratory predictive findings that are easy to collect and promptly available. We independently diagnosed TM according to a composite reference standard that included a series of microbiological tests. We performed bivariate analysis and constructed a logistic regression model to select the predictive findings associated with TM. With the selected predictors included in the model, we developed a score-based CPR. We assessed its internal validity and diagnostic performance. RESULTS: Of 155 analysed patients, 59 (38%) had TM. The CPR we derived includes three predictors: cough for 14 days or more, 10-500 cells in CSF and adenosine deaminase >= 6 U/l in CSF. It classifies patients into high-, moderate- or low-score groups and has an overall area under the ROC curve of 0.87. 59% of patients were assigned to either the high- or the low-score group, permitting prompt decision-making. In patients in the high-score group, it attains a positive likelihood ratio for TM of 10.6 and in patients with low scores, a negative likelihood ratio of 0.10. Bootstrap analysis indicated high internal validity. CONCLUSION: This CPR could support decision-making in patients with clinical suspicion of TM. External validation and further assessment of its clinical impact are necessary before application in other settings. PMID- 29446861 TI - Patterns of Posttraumatic Stress Disorder and Posttraumatic Growth Among Adolescents After the Wenchuan Earthquake in China: A Latent Profile Analysis. AB - Posttraumatic stress disorder (PTSD) and posttraumatic growth (PTG) often coexist in the survivors of traumatic events. The current study examined the coexisting patterns of PTSD and PTG using latent profile analysis in a sample of 591 adolescent survivors of the May 12, 2008 Wenchuan earthquake in China. Logistic regression analysis was used to examine the effects of traumatic exposure on specific coexisting patterns. A three-class solution characterized by a growth group (39.6%), a low symptoms group (10.3%), and a coexistence group (50.1%) fitted the data best. Members of the low symptoms group were more likely to be male, odds ratio (OR) = 2.67, 95% CI [1.48, 4.81]; and adolescents in the coexistence group were more likely to be older, OR = 1.22, 95%CI [1.09, 1.37], and to have had experienced serious indirect exposure, OR = 1.07, 95% CI [1.02, 1.12], and posttraumatic fear, OR = 1.20, 95% CI [1.11, 1.31].

PMID- 29446863 TI - Conservation value of low-productivity forests measured as the amount and diversity of dead wood and saproxylic beetles. AB - In many managed landscapes, low-productivity land comprises most of the remaining relatively untouched areas, and is often over-represented within protected areas. The relationship between the productivity and conservational value of a site is poorly known; however, it has been hypothesized that biodiversity increases with productivity due to higher resource abundance or heterogeneity, and that the species communities of low-productivity land are a nested subset of communities from more productive land. We tested these hypotheses for dead-wood-dependent beetles by comparing their species richness and composition, as well as the amount and diversity of dead wood, between low-productivity (potential forest growth <1 m3 .ha-1 .yr-1 ) and high-productivity Scots pine-dominated stands in Sweden. We included four stand types: stands situated on (1) thin soils and (2) mires (both low-productivity), (3) managed stands, and (4) unmanaged stands set aside for conservation purposes (both high-productivity). Beetle species richness and number of red-listed species were highest in the high-productivity set asides. Species richness was positively correlated with the volume and diversity of dead wood, but volume appeared to be a better predictor than diversity for the higher species richness in set-asides. Beetle species composition was similar among stand types, and the assemblages in low-productivity stands were largely subsets of those in high-productivity set-asides. However, 11% of all species and 40% of red-listed species only occurred in high-productivity stands, while no species were unique to low-productivity stands. We conclude that low-productivity forests are less valuable for conservation than high-productivity forest land. Given the generally similar species composition among stand types, a comparable conservational effect could be obtained by setting aside a larger area of low productivity forest in comparison to the high-productivity. In terms of dead wood volumes, 1.8-3.6 ha of low-productivity forest has the same value as 1 ha of unmanaged high-productivity forest. This figure can be used to estimate the conservation value of low-productivity forests; however, as high-productivity forests harbored some unique species, they are not completely exchangeable. PMID- 29446864 TI - Sensitive and Specific Guest Recognition through Pyridinium-Modification in Spindle-Like Coordination Containers. AB - An elaborately designed pyridinium-functionalized octanuclear zinc(II) coordination container 1-Zn was prepared through the self-assembly of Zn2+ , p tert-butylsulfonylcalix[4]arene, and pyridinium-functionalized angular flexible dicarboxylate linker (H2 BrL1). The structure was determined by a single-crystal X-ray diffractometer. 1-Zn displays highly sensitive and specific recognition to 2-picolylamine as revealed by drastic blueshifts of the absorption and emission spectra, ascribed to the decrease of intramolecular charge transfer (ICT) character of the container and the occurrence of intermolecular charge transfer between the host and guest molecules. The intramolecular charge transfer plays a key role in the modulation of the electronic properties and is tunable through endo-encapsulation of specific guest molecules. PMID- 29446865 TI - Guidance on the use of probiotics in clinical practice in children with selected clinical conditions and in specific vulnerable groups. AB - AIM: The use of probiotics has been covered by many guidelines, position papers and evidence-based recommendations, but few have referred to specific patient groups or clinical indications. This review summarises recommendations and scientifically credited guidelines on the use of probiotics for children with selected clinical conditions and provides practice points. METHODS: An expert panel was convened by the European Paediatric Association in June 2017 to define the relevant clinical questions for using probiotics in paediatric health care and review and summarise the guidelines, recommendations, position papers and high-quality evidence. RESULTS: The panel found that specific probiotic strains were effective in preventing antibiotic-associated and nosocomial diarrhoea, treating acute gastroenteritis and treating infantile colic in breastfed infants. However, special caution is indicated for premature infants, immunocompromised and critically ill patients and those with central venous catheters, cardiac valvular disease and short-gut syndrome. This review discusses the safety of using probiotics in selected groups of paediatric patients and the quality of the available products providing practice points based on proved findings. CONCLUSION: Efficacy of probiotics is strain specific. Their benefits are currently scientifically proven for their use in selected clinical conditions in children and not recommended for certain patient groups. PMID- 29446867 TI - Epigallocatechin Gallate Reduces Amyloid beta-Induced Neurotoxicity via Inhibiting Endoplasmic Reticulum Stress-Mediated Apoptosis. AB - SCOPE: We investigated the role of endoplasmic reticulum (ER) stress in the protective effects of EGCG against the neuronal apoptosis in Abeta1-42 -induced SH-SY5Y cells and APP/PS1 transgenic mice. METHODS AND RESULTS: Cell viability (CCK8 assay), flow cytometry, Hoechst 33258 staining, immunohistochemistry, transmission electron microscopy (TEM), and western blotting were used. EGCG prevented Abeta1-42-induced toxicity in SH-SY5Y cells, increased cell viability, and decreased apoptosis in a dose-dependent manner. In a subsequent mechanism study, it was found that this effect contributed to the down-regulation of GRP78, CHOP, cleaved-caspase-12 and -3. Moreover, EGCG also reduced the cytotoxicity induced by tunicamycin (TM) and thapsigargin (TG), two ER stress activators. Consistent with the in vitro study, EGCG inhibited neuronal apoptosis in the cortex of APP/PS1 transgenic mice, with the mitigation of ER abnormal ultrastructural swelling and the downregulation of ER-stress-associated proteins. CONCLUSION: These results indicate that EGCG attenuates the neurotoxicity in Alzheimer's disease (AD) via a novel mechanism that involves inhibition of ER stress-associated neuronal apoptosis in vitro and in vivo, suggesting the tremendous potential of EGCG for use in a nutritional preventive strategy against AD. PMID- 29446868 TI - Amyloid Polymorphism in the Protein Folding and Aggregation Energy Landscape. AB - Protein folding involves a large number of steps and conformations in which the folding protein samples different thermodynamic states characterized by local minima. Kinetically trapped on- or off-pathway intermediates are metastable folding intermediates towards the lowest absolute energy minima, which have been postulated to be the natively folded state where intramolecular interactions dominate, and the amyloid state where intermolecular interactions dominate. However, this view largely neglects the rich polymorphism found within amyloid species. We review the protein folding energy landscape in view of recent findings identifying specific transition routes among different amyloid polymorphs. Observed transitions such as twisted ribbon->crystal or helical ribbon->nanotube, and forbidden transitions such helical ribbon->crystal, are discussed and positioned within the protein folding and aggregation energy landscape. Finally, amyloid crystals are identified as the ground state of the protein folding and aggregation energy landscape. PMID- 29446866 TI - Tacrolimus concentration to dose ratio in solid organ transplant patients treated with fecal microbiota transplantation for recurrent Clostridium difficile infection. AB - Fecal microbiota transplantation (FMT) is increasingly being performed for Clostridium difficile infection in solid organ transplant (SOT) patients; however, little is known about the potential pharmacokinetic or pharmacomicrobial effects this may have on tacrolimus levels. We reviewed the medical records of 10 SOT patients from September 2012-December 2016 who were taking tacrolimus at time of FMT for recurrent C. difficile infection. We compared the differences in tacrolimus concentration/dose ratio (C/D ratio) 3 months prior to FMT vs 3 months after FMT. The mean of the differences in C/D ratio calculated as (ng/mL)/(mg/kg/d) was -17.65 (95% CI -1.25 to 0.58) (ng/mL)/(mg/kg/d), P-value .43 by Wilcoxon signed-rank test. The mean of the differences in C/D ratio calculated as (ng/mL)/(mg/d) was -0.33 (95% CI -1.25 to 0.58) (ng/mL)/(mg/d), P value .28 by Wilcoxon signed-rank test. Of these patients, 2/10 underwent allograft biopsy for allograft dysfunction in the year after FMT, with no evidence of allograft rejection on pathology. These preliminary data suggest that FMT may not predictably alter tacrolimus levels and support its safety for SOT patients however further study in randomized trials is needed. PMID- 29446869 TI - Dimensions of the medial wall of the prelacrimal recess. AB - BACKGROUND: Addressing anterior maxillary sinus pathology endoscopically that is inaccessible with an endoscopic modified medial maxillectomy requires either a prelacrimal approach (PLA) or an endoscopic Denker's approach (EDA). The PLA involves removing the medial wall of the prelacrimal recess (PLR), which is the bone between the pyriform aperture (PA) and nasolacrimal duct (NLD), from nasal floor to orbital floor. The PLA preserves the inferior turbinate and NLD, whereas both are sacrificed during an EDA. The purpose of this computed tomography (CT) based study was to determine the anteroposterior and superoinferior dimensions of the medial wall of the PLR. METHODS: One hundred thirty-one triplanar sinus CT scans of patients with various rhinologic diseases, but with intact bony PLR walls, were reviewed to assess dimensions of the medial wall of the PLR. The anteroposterior distances from the PA to the inferior-most, middle, and superior most aspects of the NLD were measured. The height from the nasal floor to orbital floor was also measured. Combining left and right sides, there were 262 measurements. RESULTS: The anteroposterior distances between the PA and the NLD were as follows: inferior: mean, 8.4 mm (standard error [SE], 0.2; range, 1.9 14.2); middle: mean, 7.6 mm (SE, 0.2; range, 0-13.6); and superior: mean, 5.5 mm (SE, 2.5; range, 0-11.9). The mean height of the medial wall of the PLR was 26.5 mm (SE, 0.2; range, 18.5-39.9). CONCLUSION: The anteroposterior and superoinferior dimensions of the medial wall of the PLR are variable, with the anteroposterior dimension being widest inferiorly. Its dimensions should be evaluated preoperatively when considering endoscopic approaches to or through the anterior maxillary sinus. PMID- 29446870 TI - Confinement Effects on the Benzene Orientational Structure. AB - Liquids under confinement exhibit different properties compared with their corresponding bulk phases, for example, miscibility, phase transitions, and diffusion. The underlying cause is the local ordering of molecules, which is usually only studied using pure simulation methods. Herein, we derive experimentally the structure of benzene confined in MCM-41 using total neutron scattering measurements. The study reveals a layering of molecules across a pore, and four concentric cylindrical shells can be distinguished for a pore with the radius of 18 A. The nanoscale confinement of the liquid has a major effect on the spatial and orientational correlations observed between the molecules, when compared with the structure of the bulk liquid. These differences are most marked for molecules in parallel configurations, and this suggests differences in chemical reactivity between the confined and bulk liquids. PMID- 29446872 TI - Does selective hormesis impact herbicide resistance evolution in weeds? ACCase resistant populations of Alopecurus myosuroides Huds. as a case study. AB - BACKGROUND: A field-evolved herbicide-resistant weed population can represent a heterogeneous composite of subpopulations that differ in their susceptibility and responsiveness to herbicide hormesis. Variable hormesis responsiveness can result in selection for and against certain subpopulations under low herbicide doses, and this has the potential to contribute to the evolution of resistance. The relevance of this hypothesis at practical field rates was studied for two field collected acetyl-coenzyme A carboxylase (ACCase) target-site resistant (TSR) biotypes of Alopecurus myosuroides Huds. (haplotype Leu1781) exposed to three ACCase inhibitors. Herbicide dose responses were evaluated at the population level and at different subpopulation levels after the dissection of individual plants by herbicide selection and genotyping. RESULTS: The practical field rates of fenoxaprop-P were lower than the observed hormetic doses in the resistant subpopulation, whereas the field rates of clodinafop and cycloxydim stimulated the shoot biomass in different resistant subpopulations by 21-38% above that of the control. Because variable dose levels induced hormesis in the different subpopulations, the practical field rates showed a significant potential to selectively enhance parts of a resistant field population, but did not impact or adversely affect other parts of the population. CONCLUSION: As a consequence of population heterogeneity, herbicide hormesis may impact resistance evolution in weeds at realistic use rates via the selective promotion of individual genotypes. However, the practical relevance of this phenomenon may be influenced by many factors, such as the herbicidal active ingredient used, as indicated in this study.

AB - BACKGROUND: Soil biosolarization is a promising alternative to conventional fumigation. Volatile fatty acids (VFAs) produced in the soil through fermentation of amended organic matter can affect pest inactivation during biosolarization. The objective was to determine how soil amended with organic wastes that were partially stabilized through either composting or anaerobic digestion affected the inactivation of Brassica nigra (BN; a weed) and Fusarium oxysporum f. sp. lactucae (FOL; a phytopathogenic fungus). RESULTS: The mortality of BN seeds in the biosolarized soil was 12% higher than in the solarized soil, although this difference was not significant. However, a significant correlation between BN mortality and VFA accumulation was observed. The number of FOL colony-forming units (CFU) in solarized samples at 5 cm was 34 CFU g-1 of soil, whereas in the biosolarized samples levels were below the limit of quantification. At 15 cm, these levels were 100 CFU g-1 for solarized samples and < 50 CFU g-1 of soil for the biosolarized samples. Amendment addition positively affected the organic matter and potassium content after the solarization process. CONCLUSION: The organic waste stabilization method can impact downstream biosolarization performance and final pest inactivation levels. This study suggests that organic waste management practices can be leveraged to improve pest control and soil quality. (c) 2018 Society of Chemical Industry.

AB - ST36 is a commonly-used acupoint in traditional Chinese medicine (TCM) for treatment of inflammations, pains and gastrointestinal disturbs. For decades, the low power laser acupuncture has been widely applied as an alternative therapy to traditional metal needle acupuncture and achieved relatively fine therapeutic effect for ST36-related symptoms with reduction of uncomfortableness and infection risks. However its disadvantages of low penetrativity and lack of manipulation skills limit its potential performance. An optical fiber laser acupuncture introduced by the previous study combines traditional needling acupuncture and the laser stimulation together, making a stronger therapeutic effect and showing a potential value in clinical application. To evaluate its acupunctural effect on blood, mice are taken as experimental model and Raman spectroscopic technique is used to analysis the changes of blood components after stimulating on ST36. The results show that both the traditional needling acupuncture and optical fiber acupuncture could lead to some spectral changes of blood in mice. This study explores the optical fiber acupuncture's effect on blood in mice using Raman spectroscopy technique for mechanism of acupuncture therapy. PMID- 29446874 TI - Transplant recipients are vulnerable to coverage denial under Medicare Part D. AB - Transplant immunosuppressants are often used off-label because of insufficient randomized prospective trial data to achieve organ-specific US Food and Drug Administration (FDA) approval. Transplant recipients who rely on Medicare Part D for immunosuppressant drug coverage are vulnerable to coverage denial for off label prescriptions, unless use is supported by Centers for Medicare & Medicaid Services (CMS)-approved compendia. An integrated dataset including national transplant registry data and 3 years of dispensed pharmacy records was used to identify the prevalence of immunosuppression use that is both off-label and not supported by CMS-approved compendia. Numbers of potentially vulnerable transplant recipients were identified. Off-label and off-compendia immunosuppression regimens are frequently prescribed (3-year mean: lung 66.5%, intestine 34.2%, pancreas 33.4%, heart 21.8%, liver 16.5%, kidney 0%). The annual retail cost of these at-risk medications exceeds $30 million. This population-based study of transplant immunosuppressants vulnerable to claim denials under Medicare Part D coverage demonstrates a substantial gap between clinical practice, current FDA approval processes, and policy mandates for pharmaceutical coverage. This coverage barrier reduces access to life-saving medications for patients without alternative resources and may increase the risk of graft loss and death from medication nonadherence.

AB - Politicians, government officials, business representatives, and nongovernmental climate activists all in various ways emphasize what they see as progress being made in the aftermath of the Paris Agreement, even if they continue to warn of the dire consequences of business as usual. Indeed, there is no lack of encouraging private and public sector initiatives on climate change. Some macro trends seem to be moving in the right direction, as well. But, closer scrutiny shows that these positive trends are still far from adding up to the necessary fundamental shift in the global energy economy. Furthermore, the public may greatly overestimate the advancement of renewable solar and wind energy technology, which contributes to a false sense of progress and lessens political urgency. Without determined and reinvigorated political leadership from the European Union (EU), there is little hope that necessary emission reduction goals to stay below 2 degrees C above preindustrial levels can be met. The EU has driven international climate policy from the beginning of climate negotiations, and there is unfortunately no other source of leadership in sight. It will require difficult political decisions to be taken sooner rather than later to force a much quicker domestic energy transition and to raise financing to help developing countries with their own energy transition and adaptation to a rapidly warming world.

AB - Cerebral palsy (CP) considerably impairs the ability to maintain upright stance. In the present study the effects of locomotor training and functional electrical stimulation (FES) on postural control have been determined in children (n = 27) aged 6-12 years with severe CP. The severity level of the CP clinical manifestations was determined as 3 according to the Gross Motor Function Classification System (GMFCS) classification. All patients participated in 15 half-hour sessions of mechanic therapy using robot-assisted passive stepping. In 12 out of 27 children, the locomotion therapy was accompanied with FES. Stabilometry and plantography tests were performed before and after the course of interventions. In addition, similar posturographics tests were performed in 23 healthy children same age. Postural control in children with CP was characterized by a forward shift of the center of pressure (COP) projection; higher values of the COP trajectory area and length, as weel as by mean amplitude of the COP oscillations, and the absence of COP response to the eyes closed condition. After treatment, the posturographic characteristics had a tendency to normalization in relation to the values obtained in neurologically intact children. The improvement was observed in 43% of children without FES and in 75% of children which used FES. Analysis of plantograms revealed normalization of footprints in children received FES. Thus, it was demonstrated that FES combined with locomotor training resulted in the improvement in vertical posture control in children with severe CP.

AB - Using spectral, wavelet, multifractal, and recurrence analyses we examined the features of involuntary shaking (tremor) arising during the performance of a given motor task. The task was to maintain the efforts of fingers under isometric conditions by a healthy subject, a patient with primary bilateral parkinsonism, and a patient with a syndrome of the essential tremor. The physiological tremor was characterized by the minimal amplitude, the broad power spectrum, the minimal energy of the wavelet spectrum, the maximal degree of multifractality, the minimal degree of determinism, and the maximal entropy of recurrence time density. In the case of the essential tremor we observed the significant enhancement of the wavelet spectrum energy and the decrease of the oscillation complexity. It was evident as the appearance of clear peaks in the power spectra, the fall in the multifractality degree, the emergence of a quasiperiodic structure in the recurrence diagrams, the grow of determinism and the decrease of the entropy of recurrence time density. All these trends were enhanced for the parkinsonian tremor. The suggested characteristics enable us to estimate the degree of deviation of the motor function from the healthy one.

AB - A pattern of cortical functional connectivity in the source space was studied in a group of right-handed adult participants (N = 44:17 women, 27 men, aged M = 29.61 +/- 6.45 years) who retained in their working memory (WM) traces of realistic pictures of positive, neutral, and negative emotional valence while in their working memory (WM) while performing same different task in which participants had to compare an etalon picture against a target picture that followed after a specified delay. A coherence (COH) between pairs of cortical sources chosen in advance according to fMRI data was estimated in the theta frequency range for the period of time preceding the etalon stimulus, distinct sets of functional links are found. The links of the first type that presumably reflect the involvement of sustained attention were between the dorsal anterior cingulate cortex, the prefrontal areas, and temporal areas of the right hemispheres. When compared to the rest period, links of this type showed strengthening not only during the retention period but also during the period preceding the etalon picture. The links of the second type presumably reflecting a progressive neocortex-to-hippocampus functional integration with increasing memory load and strengthened exclusively during retention period. Those links were between parietal, temporal and prefrontal cortices in the lateral surface of both hemispheres with the additional inclusion of the posterior cingulate cortex and the medial parietal cortex in the left hemisphere. An impact of emotional valence onto the strength and topography of the functional links of the second type was found. In the left hemisphere, an increase in the strength of cortical interaction was more pronounced for pictures of positive valence than for pictures of either neutral or negative valences. When compared to the pictures of neutral valence, the retention of pictorial information of both positive and negative valence showed some extraneous integration of the cortical areas for the theta rhythm. This finding might be related to the additional load exerted by emotionally colored pictures onto the mechanisms of short-time retention of visual information.

AB - We studied the ability of invariant recognition of the form of visual images concerning color, size and location of the image in 5-6 year-old children with typical and atypical patterns of development. It was found that the children of this age with typical development are able to identify the invariant form of a visual object regardless of any changes in its color, size or location. Children with neurodevelopmental disorders have difficulties with identifying the form of a visual object when its location is changed among a large number of figures. In children with early infantile autism, we observed different degrees of visual perception deficit. Children with milder forms of autistic disorders have difficulties only with recognizing the forms of an image when its location is changed; children with more severe forms of disorders, we observed serious disability of invariant recognition regardless of the color, size and location of images.

AB - This study presents the results of the pre- and postflight clinical and physiological examination (CPE) and scientific experiment "Sensory Adaptation-2" carried out in Yu.A. Gagarin Research & Test Cosmonaut Training Center. There were examined 14 Russian cosmonauts, crewmembers of long-term international spaceflights ISS-28/29 to ISS 36/37, who were in microgravity from 159 to 195 days. Age of the cosmonauts was 35-50 years. Studies were conducted twice before space flight (baseline), and on days R+1(2), R+4(5), and R+8(9) after landing. In the study of visual-manual tracking (VMT), eye movements were recorded by the electrooculography method (EOG), hand movements - by a joystick using biological visual feedback (on the screen represented the current angle/position of a joystick). Examinations were conducted using computerized stimulation programs, which were presented on the screen of the hardware-software complex "Sensomotor". Examinations of the VMT took place in the dialog mode and included the following sections: a) EOG-calibration; b) visual-manual tracking within +/-10 degrees on the screen with blank background (smooth linear and sinusoidal movement of a point target with a frequency of 0.16 Hz in the vertical and horizontal directions). There were evaluated time, amplitude, and velocity characteristics of visual and manual tracking (VT and MT), including the effectiveness (EC) and gain (GC) coefficients which were calculated respectively, as the ratio of amplitude and velocity of the visual stimulus (target). A study of the vestibular function (VF) was performed before and after space flight using videooculography. There were assessed static torsion otolith-cervical-ocular reflex, dynamic vestibular-cervical-ocular reactions, vestibular reactivity, spontaneous eye movements. Study of VF in the first postflight has shown a sharp decrease (up to its complete absence) of static vestibular excitability (otolith reflex) accompanied by the increased dynamic reactivity of the vestibular system. Study of VTM has shown a significant decrease of gain and effectiveness/amplitud of VT in the first days postflight, as well as correlation between the parameters of VF and MT, between the VF and VT, and no found correlation between parameters of VF and MT. It was found that the conditions of space flight (microgravity) have a greater impact on the accuracy of the VT than the accuracy of MT. Full return of characteristics of the VMT and VF to the baseline was observed on R+8(9) days after space flight. PMID- 29446900 TI - [Noise affect to the fragmented contour image recognition]. AB - We performed a comparison of the results of recognition of fragmented outline images in the presence of noise and without it. Contour images and visual noise were synthesized form Gabor elements. Distances between the Gabor elements in contour and in noise were changed and image sizes varied too. The percentage of correct responses was not dependent on the size of the stimuli, but differed for the same objects in the noise and without noise. The percentage of recognition was higher for images with lots of turns in case without noise. The recognition in noise was better for contour images having lines with slightly varying curvature. Identification in noise depended on the ration of the distances between the elements in noise and in contour.

AB - We studies the differences in oscillatory responses to emotional facial expressions in 40 subjects with different severity of depressive symptoms (19 men and 21 women) aged 18-30 years. In subjects with low severity of depressive symptoms (group 2), the perception of happy facial expressions was marked by lower delta synchronization as compared with angry and neutral expressions; in subjects with high severity of depressive chronization as compared with angry and neutral expression; in subjects with high severity of depressive symptoms (group 1), the perception of happy faces was marked by higher delta synchronization. Since an increase in delta oscillations is usually observed in aversive conditions, we suggest that happy facial expressions are perceived as negative stimuli by the subjects of group 1. The perception of angry facial expressions was accompanied by alpha band desynchronization in Group 2 and by alpha synchronization in Group 1. Basing on Klimesch's theory, this effect suggests that the subjects of group 1 are initially set up for the perception of negative emotional information. The effect of emotional stimulus category was significant in group 2, but not significant in group 1, which is an evidence of disorders in the recognition of emotional information in depression-prone individuals.

Three clusters of patients were formed with the use of the Gorbov-Shulte performance test. The patients of "low efficiency" cluster were characterized by the lack of habituation mechanisms in the activity of afferent systems and mechanism of motor response; the activity rate of stress adaptation systems and the rate of intrasystemic tension during the preparation to purposeful activities were higher than in patients of "intermediate" and "high performance" clusters.

AB - We studied the interrelations between G/A-polymorphism of EPAS 1 gene(rs1867785) and macimal oxygen consumption (VO2max) in Russian male athletes. There were two groups in the study: athletes of different sport specialization (n = 241) and nonathletic males (n = 92). It was found that the frequency of AA and AG genotype of EPAS1 gene in the group of athletes was higher (chi2 = 14.16, p = 0.03). In the subgroups with average (EPAS1*A 38.1% and EPAS1*G 61.9%) and high ((EPAS1*A 41.8% and EPAS1*G 58.2%) VO2max values, the frequency of these alleles was significantly different from those in the control group (chi2 = 7.53, p = 0.006 and chi2 = 6.58, p = 0.01, respectively). This suggests that higher aerobic capacities are caused by the presence of at least one minor A-Allele of the EPAS1 gene in the genome of an athlete.

AB - Alcohol-induced muscle damage (AIMD) - an umbrella term that includes all forms of alcoholic myopathy developing in acute or chronic alcohol intoxication. The most common form of destruction of skeletal muscle in alcoholism is a chronic alcoholic myopathy, which develops independently of other manifestations of alcoholism, such as polyneuropathy, malabsorption syndrome, liver damage, but can be combined with them. The basis of the destruction of skeletal muscle in chronic AIPM is atrophy of muscle fibers. Mainly affects muscle fiber type II with less destruction of type ! fibers. Currently, the pathogenesis of chronic alcoholic myopathy is studied. The imbalance of protein synthesis and proteolysisand increased apoptosis rate are discussed. PMID- 29446912 TI - Cathodic Corrosion of a Bulk Wire to Nonaggregated Functional Nanocrystals and Nanoalloys. AB - A key enabling step in leveraging the properties of nanoparticles (NPs) is to explore new, simple, controllable, and scalable nanotechnologies for their syntheses. Among "wet" methods, cathodic corrosion has been used to synthesize catalytic aggregates with some control over their size and preferential faceting. Here, we report on a modification of the cathodic corrosion method for producing a range of nonaggregated nanocrystals (Pt, Pd, Au, Ag, Cu, Rh, Ir, and Ni) and nanoalloys (Pt50Au50, Pd50Au50, and Ag xAu100- x) with potential for scaling up the production rate. The method employs poly(vinylpyrrolidone) (PVP) as a stabilizer in an electrolyte solution containing nonreducible cations (Na+, Ca2+), and cathodic corrosion of the corresponding wires takes place in the electrolyte under ultrasonication. The ultrasonication not only promotes particle PVP interactions (enhancing NP dispersion and diluting locally high NP concentration) but also increases the production rate by a factor of ca. 5. Further increase in the production rate can be achieved through parallelization of electrodes to construct comb electrodes. With respect to applications, carbon supported Pt NPs prepared by the new method exhibit catalytic activity and durability for methanol oxidation comparable or better than the commercial benchmark catalyst. A variety of Ag xAu100- x nanoalloys are characterized by ultraviolet-visible absorption spectroscopy and high-resolution transmission electron microscopy. The protocol for NP synthesis by cathodic corrosion should be a step toward its further use in academic research as well as in its practical upscaling.

AB - Transition metal dichalcogenides can be synthesized in a wide range of structures. 1D geometries, including nanotubes and nanowires, are especially intriguing due to enhanced light-matter interactions stemming from both the thickness and width possessing subwavelength dimensions. In this letter, we demonstrate the synthesis of 1D MoS2 nanobelts through chemical vapor deposition and examine the mechanism driving the formation of this material. We also report enhanced light scattering within these structures. Finally, we investigate the phototransistor behavior of MoS2 nanobelts and observed a photoresponsivity around 1.5 A/W, an order of magnitude greater than analogous multilayer 2D MoS2 sheets reported previously.

AB - Abnormal expression of C-terminal p53 isoforms alpha, beta, and gamma can cause the development of cancers including breast cancer. To date, much evidence has demonstrated that these isoforms can differentially regulate target genes and modulate their expression. Thus, quantification of individual isoforms may help to link clinical outcome to p53 status and to improve cancer patient treatment. However, there are few studies on accurate determination of p53 isoforms, probably due to sequence homology of these isoforms and also their low abundance. In this study, a targeted proteomics assay combining molecularly imprinted polymers (MIPs) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) was developed for simultaneous quantification of C-terminal p53 isoforms. Isoform specific surrogate peptides (i.e., KPLDGEYFTLQIR (peptide-alpha) for isoform alpha, KPLDGEYFTLQDQTSFQK (peptide-beta) for isoform beta, and KPLDGEYFTLQMLLDLR (peptide-gamma) for isoform gamma) were first selected and used in both MIPs enrichment and mass spectrometric detection. The common sequence KPLDGEYFTLQ of these three surrogate peptides was used as single template in MIPs. In addition to optimization of imprinting conditions and characterization of the prepared MIPs, binding affinity and cross-reactivity of the MIPs for each surrogate peptide were also evaluated. As a result, a LOQ of 5 nM was achieved, which was >15-fold more sensitive than that without MIPs. Finally, the assay was validated and applied to simultaneous quantitative analysis of C-terminal p53 isoforms alpha, beta, and gamma in several human breast cell lines (i.e., MCF-10A normal cells, MCF-7 and MDA-MB-231 cancer cells, and drug-resistant MCF-7/ADR cancer cells). This study is among the first to employ single template MIPs and cross reactivity phenomenon to select isoform-specific surrogate peptides and enable simultaneous quantification of protein isoforms in LC-MS/MS-based targeted proteomics. PMID- 29446915 TI - Radially Aligned Hierarchical Nickel/Nickel-Iron (Oxy)hydroxide Nanotubes for Efficient Electrocatalytic Water Splitting. AB - Designing well-controlled hierarchical structures on micrometer and nanometer scales represents one of the most important approaches for upgrading the catalytic abilities of electrocatalysts. Although NiFe (oxy)hydroxide has been widely studied as a water oxidation catalyst due to its high catalytic capability and abundance, its structural manipulation has been greatly restricted due to its inherent crystallographic stacking feature. In this work, we report for the first time the construction of a nanotube structure of NiFe (oxy)hydroxide with an inner Ni-rich layer, which was radially aligned on a macroporous nickel foam. Such a hierarchically structured material realized several crucial factors that are essential for excellent catalytic behaviors, including abundant catalytic sites, a high surface area, efficient ionic and electronic transport, etc., and the designed catalyst exhibited competitive electrocatalytic activity for reaction of not only oxygen evolution but also hydrogen evolution, which is very rare. As a result, this novel material was well-suited for the use as a bifunctional catalyst in an integrated water-splitting electrolyzer, which could be even driven by a single AA battery or a 1.5 V solar cell, outperforming a benchmark catalyst of noble-metal ruthenium-platinum combinations and most state of-the-art electrocatalysts. The work provided important suggestions for the rational modulation of catalysts with new structures targeted for high performance electrodes used in electrochemical applications. PMID- 29446916 TI - A Smart DNA Tweezer for Detection of Human Telomerase Activity. AB - Reliable and accurate detection of telomerase activity is crucial to better understand its role in cancer cells and to further explore its function in cancer diagnosis and treatment. Here, we construct a smart DNA tweezer (DT) for detection of telomerase activity. The DT is assembled by three specially designed single-stranded oligonucleotides: a central strand dually labeled with donor/acceptor fluorophores and two arm strands containing overhangs complementary to telomerase reaction products (TRPs). It can get closed through hybridization with TRPs and get reopen through strand displacement reaction by TRPs' complementary sequences. First, under the action of telomerase, telomerase binding substrates (TS) are elongated to generate TRPs ended with telomeric repeats (TTAGGG) n. TRPs hybridize with the two arm overhangs cooperatively and strain DT to closed state, inducing an increased fluorescence resonance energy transfer (FRET) efficiency, which is utilized for telomerase activity detection. Second, upon introduction of a removal strand (RS) complementary to TRPs, the closed DT is relaxed to open state via the toehold-mediated strand displacement, inducing a decreased FRET efficiency, which is utilized for determination of TRP length distribution. The detection limit of telomerase activity is equivalent to 141 cells/MUL for HeLa cells, and telomerase-active cellular extracts can be differentiated from telomerase-inactive cellular extracts. Furthermore, TRPs owning 1, 2, 3, 4, and >=5 telomeric repeats are identified to account for 25.6%, 20.5%, 15.7%, 12.5%, and 25.7%, respectively. The proposed strategy will offer a new approach for reliable, accurate detection of telomerase activity and product length distribution for deeper studying its role and function in cancer. PMID- 29446917 TI - Mapping the mAb Aggregation Propensity Using Self-Interaction Chromatography as a Screening Tool. AB - The osmotic second virial coefficient ( B2), which describes protein-protein molecular interactions in solution, was determined using self-interaction chromatography (SIC) for an IgG1-type mAb across a wide range of solution conditions. These data were compared with its time dependent aggregation behavior, as determined using size-exclusion chromatography (SEC), and its temperature dependent aggregation behavior using dynamic light scattering (DLS) over a four-week period (SEC) or overnight (DLS). DLS and SEC gave consistent data on aggregation behavior, which correlated well with experimental B2 trends across the wide pH (4-9) and NaCl concentration (0-1.0 M) ranges studied. The IgG aggregated at pH 4 for 0.5-1.0 M NaCl concentrations and for 0 M NaCl concentrations at pH 8. Best stability against aggregation was exhibited for the pH range from 5 to 8 at 0.8-1.0 M NaCl. SIC data were able to be classified within the one-day solution conditions for aggregation, which were not identified for 2-3 weeks in the accelerated SEC stability study. The ability of SIC to provide such data rapidly reflects the fundamentally thermodynamic nature of this parameter and of the aggregation process itself. Proteins with attractive protein protein interactions and negative B2 coefficients in the range -3 to -6 clearly exhibit aggregation behavior, while B2 values in the range 0 to 2 showed good stability toward aggregation. SIC allows the rapid screening of solution conditions for which mAbs will exhibit stability to aggregation while requiring 90% less time and material compared with that required for a conventional SEC aggregation study. PMID- 29446919 TI - Evolution of NiO Island Size Distributions during the Oxidation of a Ni-5Cr Alloy: Experiment and Modeling. AB - The classic models of metal oxidation developed by Wagner and Cabrera and Mott presuppose the existence of a planar oxide film and develop expressions for the rate at which the film thickens. Missing from those models is a description of how that initially planar film forms. Using scanning tunneling microscopy, we study the growth of NiO islands on the (100) surface of a Ni-5Cr alloy during the oxidation regime where the initial planar film is formed as oxide islands. The island height and area distributions as a function of the oxygen exposure in Langmuir (1 L = 10-6 Torr s) are measured. Lateral island growth and thickening occur as seemingly separate processes, and after a critical thickness of ~0.4 nm is achieved, growth is purely in the lateral direction. We develop a surface diffusion model for the evolution of the island size distribution that accounts for the lateral growth and coalescence of the NiO islands. Our results indicate that the oxygen surface diffusion screening length [Formula: see text] controls the island evolution. The screening length is found to be 0.3-0.4 nm, which suggests that the processes leading to island growth are highly localized to the island edge.

AB - We report blue, green, and red upconversion emissions with strongly angular dependent intensities for a new type of hybrid (Y,Yb,Er)-pyrazine thin films realized using the atomic/molecular layer deposition thin-film fabrication technology. The luminescence emissions in our amorphous (Y,Yb,Er)-pyrazine thin films of a controllable nanothickness originate from three- and two-photon NIR-to vis excitation processes. In addition to shielding the lanthanide ions from nonradiative de-excitation, the network of interconnected organic molecules serves as an excellent matrix for the Yb3+-to-Er3+ excitation energy transfer. This suggests a new approach to achieve efficient upconverting molecular materials with the potential to be used for next-generation medical diagnostics, waveguides, and surface-sensitive detectors. PMID- 29446920 TI - Homogeneous Noncompetitive Luminescent Immunodetection of Small Molecules by Ternary Protein Fragment Complementation. AB - The homogeneous immunological detection of small molecules at high sensitivity is still a daunting task. Here, we tried sensitive noncompetitive detection of small peptides based on the open-sandwich immunoassay principle, which was combined with a bioluminescent protein-fragment complementation assay (PCA) in vitro. Since the detection of antigen-induced approximation of the two antibody variable region fragments VH and VL by the standard Nanoluc-based PCA utilizing larger (LgBiT) and shorter (SmBiT) fragments was not successful, we decided to further split LgBiT into two, yielding smaller N-terminal derivative (LnBiT) and two C terminal, 11 residue peptides (LcBiT and SmBiT) corresponding to consecutive beta strands, to which VH and VL were each fused and expressed in Escherichia coli cells. Through the optimization of reaction conditions and peptide sequence, the antigen osteocalcin peptide can be noncompetitively detected with a low background signal and limit of detection, yielding a high light emission of 88% compared to that of the wild-type enzyme. Since the luminescence of this open sandwich bioluminescent immunoassay (OS-BLIA) can be observed with the naked eye, it could become the foundation of many point-of-care detection systems. PMID- 29446921 TI - Modeling of Pharmaceutical Biotransformation by Enriched Nitrifying Culture under Different Metabolic Conditions. AB - Pharmaceutical removal could be significantly enhanced through cometabolism during nitrification processes. To date, pharmaceutical biotransformation models have not considered the formation of transformation products associated with the metabolic type of microorganisms. Here we report a comprehensive model to describe and evaluate the biodegradation of pharmaceuticals and the formation of their biotransformation products by enriched nitrifying cultures. The biotransformation of parent compounds was linked to the microbial processes via cometabolism induced by ammonium-oxidizing bacteria (AOB) growth, metabolism by AOB, cometabolism by heterotrophs (HET) growth, and metabolism by HET in the model framework. The model was calibrated and validated using experimental data from pharmaceutical biodegradation experiments at realistic levels, taking two pharmaceuticals as examples, i.e., atenolol and acyclovir. Results demonstrated the good predictive performance of the established biotransformation model under different metabolic conditions, as well as the reliability of the established model in predicting different pharmaceutical biotransformations. The linear positive correlation between ammonia oxidation rate and pharmaceutical degradation rate confirmed the major role of cometabolism induced by AOB in the pharmaceutical removal. Dissolved oxygen was also revealed to be capable of regulating the pharmaceutical biotransformation cometabolically, and the substrate competition between ammonium and pharmaceuticals existed especially at high ammonium concentrations.

AB - The ligand-controlled Markovnikov and anti-Markovnikov hydrocarboxylation of styrenes with atmospheric pressure of CO2 at room temperature using dual visible light-nickel catalysis has been developed. In the presence of neocuproine as ligand, the Markovnikov product is obtained exclusively, while employing 1,4 bis(diphenylphosphino)butane (dppb) as the ligand favors the formation of the anti-Markovnikov product. A range of functional groups and electron-poor, neutral, as well as electron-rich styrene derivatives are tolerated by the reaction, providing the desired products in moderate to good yields. Preliminary mechanistic investigations indicate the generation of a nickel hydride (H-NiII) intermediate, which subsequently adds irreversibly to styrenes.

The biquinoline diimine ligand extends the PS light absorbing properties into the visible with a maximum absorption at 455 and 505 nm for NN = biq and dmebiq, respectively, in CH2Cl2 solvent. Following photoexcitation, both Cu(I) PS are emissive at low energy, albeit displaying stark differences in their excited state lifetimes (tauMLCT = 410 +/- 5 (biq) and 44 +/- 4 ns (dmebiq)). Cyclic voltammetry indicates a Cu-based HOMO and NN-based LUMO for both complexes, whereby the methyl ester substituents stabilize the LUMO within [Cu(Xantphos)(dmebiq)]+ by ~0.37 V compared to the unsubstituted analogue. When combined with H2O, N,N-dimethylaniline (DMA) electron donor, and cis [Rh(NN)2Cl2]PF6 (NN = Me2bpy = 4,4'-dimethyl-2,2'-bipyridine, bpy = 2,2' bipyridine, dmebpy = 2,2'-bipyridine-4,4'-dimethyl ester) water reduction catalysts (WRC), photocatalytic H2 evolution is only observed using the [Cu(Xantphos)(biq)]+ PS. Furthermore, the choice of cis-[Rh(NN)2Cl2]+ WRC strongly affects the catalytic activity with turnover numbers (TONRh = mol H2 per mol Rh catalyst) of 25 +/- 3, 22 +/- 1, and 43 +/- 3 for NN = Me2bpy, bpy, and dmebpy, respectively. This work illustrates how ligand modification to carefully tune the PS light absorbing, excited state, and redox-active properties, along with the WRC redox potentials, can have a profound impact on the photoinduced intermolecular electron transfer between components and the subsequent catalytic activity.

AB - Two copper(II)-carboxylate disulfide coordination polymers [Cu2((O2CPhS)2)2(H2O)2] n (1, 2) and one copper(I)-thiolate coordination polymer [Cu( p-SPhCO2H)] n (3) have been synthesized using either the 4-mercaptobenzoic acid (HSPhCO2H) or the 4,4'-dithiodibenzoic acid ((SPhCO2H)2) as ligand. These three compounds were characterized by X-ray diffraction, IR, and thermogravimetric analyses. Compounds 1 and 2 are polymorphs with the presence, for both, of dinuclear paddle-wheel copper(II)-carboxylates. In 1, the adjacent dimeric Cu2 units are linked by two (O2CPhS)2 ligands generating a cyclic loop chain, and in 2, each pair of Cu (II) atoms is linked by four ligands to create 2D networks, that are 2-fold interpenetrated. Compound 3 presents a lamellar structure, with an exceptional thermal and chemical stability, and exhibits intrinsic multiple emission between 485 and 660 nm. The different intensities of these bands generate a cyclic luminescence thermochromism from yellow to green to yellow.

AB - We assessed the gaseous, particulate, and genotoxic pollutants from two current technology gasoline direct injection vehicles when tested in their original configuration and with a catalyzed gasoline particulate filter (GPF). Testing was conducted over the LA92 and US06 Supplemental Federal Test Procedure (US06) driving cycles on typical California E10 fuel. The use of a GPF did not show any fuel economy and carbon dioxide (CO2) emission penalties, while the emissions of total hydrocarbons (THC), carbon monoxide (CO), and nitrogen oxides (NOx) were generally reduced. Our results showed dramatic reductions in particulate matter (PM) mass, black carbon, and total and solid particle number emissions with the use of GPFs for both vehicles over the LA92 and US06 cycles. Particle size distributions were primarily bimodal in nature, with accumulation mode particles dominating the distribution profile and their concentrations being higher during the cold-start period of the cycle. Polycyclic aromatic hydrocarbons (PAHs) and nitrated PAHs were quantified in both the vapor and particle phases of the PM, with the GPF-equipped vehicles practically eliminating most of these species in the exhaust. For the stock vehicles, 2-3 ring compounds and heavier 5-6 ring compounds were observed in the PM, whereas the vapor phase was dominated mostly by 2-3 ring aromatic compounds.

AB - The mechanism of B(C6F5)3 promoted Cp*CoIII-catalyzed C-H functionalization was investigated in detail employing density functional theory (DFT). The formation free energy of every possible species in the multicomponent complex system was explored and the optimal active catalyst was screened out. The results uncover the role of B(C6F5)3 played in forming active catalyst is from the coordination with OAc-, but not from the formation of [I(C6F5)3B]-, and no acceleration effect is found in C-H activation as well as the formation of CoIII-carbene intermediate. Moreover, present theoretical results elucidate the Cp*CoIII catalyzed C-H activation is mediated by imine N-coordination other than general proposed the sequence of N-deprotonation directed C-H activation. The metal controlled C-H/N-H selectivity was then elucidated by insighting into [Cp*CoIIIOAc]+/[Cp*RhIIIOAc]+-catalyzed C-H and N-H activations, respectively.

AB - When zerovalent iron (ZVI) is used in reductive removal of contaminants from industrial wastewater, where dissolved oxygen (DO) competes with target contaminant for the electrons donated by ZVI, both the reactivity and the electron selectivity (ES) of ZVI toward target contaminant are critical. Thus, the reactivity and ES of two sulfidated ZVI (S-ZVI) samples, synthesized by ball milling with elemental sulfur (S-ZVIbm) and reacting with Na2S (S-ZVINa2S), toward Cr(VI) under aerobic conditions were investigated. Sulfidation appreciably increased the reactivity of ZVI and the ratio of the rate constants for Cr(VI) removal by S-ZVIbm or S-ZVINa2S to their counterparts without sulfur fell in the range of 1.4-29.9. ES of S-ZVIbm and S-ZVINa2S toward Cr(VI) were determined to be 14.6% and 13.3%, which were 10.7- and 7.5-fold greater than that without sulfidation, respectively. This was mainly ascribed to the greater improving effect of sulfidation on the reduction rate of Cr(VI) than that of DO by ZVI. The improving effects of sulfidation on the performance of ZVI were mainly due to the following mechanisms: sulfidation increased the specific surface area of ZVI, the FeS x layer facilitated the enrichment of Cr(VI) anions on S-ZVI surface because of its anions selective property and favored the electron transfer from Fe0 core to Cr(VI) at the surface because of its role as efficient electron conductor.

AB - Manganese-alkylperoxo species have been proposed as important intermediates in certain enzymatic pathways and are presumed to play a key role in catalytic substrate oxidation cycles involving manganese catalysts and peroxide oxidants. However, structural and spectroscopic understanding of these intermediates is very limited, with only one series of synthetic MnIII-alkylperoxo complexes having been reported. In the present study, we describe the formation and properties of two new MnIII-alkylperoxo complexes, namely, [MnIII(OO tBu)(dpaq)]+ and [MnIII(OO tBu)(dpaq2Me)]+, which utilize the anionic, amide-containing pentadentate dpaq ligand platform. These complexes were generated by reacting the corresponding MnII precursors with a large excess of tBuOOH at -15 degrees C in MeCN. In both cases, the corresponding mononuclear MnIII-hydroxo complexes [MnIII(OH)(dpaq)]+ and [MnIII(OH)(dpaq2Me)]+ are observed as intermediates en route to the MnIII-alkylperoxo adducts. These new MnIII-alkylperoxo complexes were characterized by electronic absorption, infrared, and Mn K-edge X-ray absorption spectroscopies. Complementary density functional theory calculations were also performed to gain insight into their bonding and structural properties. Compared to previously reported MnIII-alkylperoxo adducts, the MnIII centers in these complexes exhibit significantly altered primary coordination spheres, with a strongly donating anionic amide nitrogen located trans to the alkylperoxo moiety. This results in MnIII-alkylperoxo bonding that is dominated by sigma interactions between the alkylperoxo piip*(O-O) orbital and the Mn d z2 orbital. PMID- 29446931 TI - Reactivity of Two-Electron-Reduced Boron Formazanate Compounds with Electrophiles: Facile N-H/N-C Bond Homolysis Due to the Formation of Stable Ligand Radicals. AB - The reactivity of a boron complex with a redox-active formazanate ligand, LBPh2 [L = PhNNC( p-tol)NNPh], was studied. Two-electron reduction of this main-group complex generates the stable, nucleophilic dianion [LBPh2]2-, which reacts with the electrophiles BnBr and H2O to form products that derive from ligand benzylation and protonation, respectively. The resulting complexes are anionic boron analogues of leucoverdazyls. N-C and N-H bond homolysis of these compounds was studied by exchange NMR spectroscopy and kinetic experiments. The weak N-C and N-H bonds in these systems derive from the stability of the resulting borataverdazyl radical, in which the unpaired electron is delocalized over the four N atoms in the ligand backbone. We thus demonstrate the ability of this system to take up two electrons and an electrophile (E+ = Bn+, H+) in a process that takes place on the organic ligand. In addition, we show that the [2e-/E+] stored on the ligand can be converted to E* radicals, reactivity that has implications in energy storage applications such as hydrogen evolution.

AB - Purification of the C8 alkylaromatics o-xylene, m-xylene, p-xylene, and ethylbenzene remains among the most challenging industrial separations, due to the similar shapes, boiling points, and polarities of these molecules. Herein, we report the evaluation of the metal-organic frameworks Co2(dobdc) (dobdc4- = 2,5 dioxido-1,4-benzenedicarboxylate) and Co2( m-dobdc) ( m-dobdc4- = 4,6-dioxido-1,3 benzenedicarboxylate) for the separation of xylene isomers using single-component adsorption isotherms and multicomponent breakthrough measurements. Remarkably, Co2(dobdc) distinguishes among all four molecules, with binding affinities that follow the trend o-xylene > ethylbenzene > m-xylene > p-xylene. Multicomponent liquid-phase adsorption measurements further demonstrate that Co2(dobdc) maintains this selectivity over a wide range of concentrations. Structural characterization by single-crystal X-ray diffraction reveals that both frameworks facilitate the separation through the extent of interaction between each C8 guest molecule with two adjacent cobalt(II) centers, as well as the ability of each isomer to pack within the framework pores. Moreover, counter to the presumed rigidity of the M2(dobdc) structure, Co2(dobdc) exhibits an unexpected structural distortion in the presence of either o-xylene or ethylbenzene that enables the accommodation of additional guest molecules. PMID- 29446933 TI - Dietary Sodium Butyrate Supplementation Reduces High-Concentrate Diet Feeding Induced Apoptosis in Mammary Cells in Dairy Goats. AB - Eighteen lactating goats (38.86 +/- 2.06 kg) were randomly allocated to three groups. One group was fed a low-concentrate (LC) diet (forage:concentrate = 6:4), while the other two groups were fed a high-concentrate (HC) diet (forage:concentrate = 4:6) or an HC diet supplemented with sodium butyrate (BHC) for 20 weeks. Samples of ruminal fluid, milk, hepatic blood plasma, and mammary gland tissue were prepared for the experimental analysis. The lipopolysaccharide (LPS) concentration, caspase-3 and -8 enzymatic activity, caspase-3 and -8 mRNA expression, and NF-kappaB (p65), phosphorylated-p65, bax, cytochrome c, and caspase-3 protein expression were higher in the HC group than those in the LC group; however, the levels of these parameters were lower in the BHC group than those in the HC group. Moreover, bcl-2 mRNA and protein expression was higher in the BHC group than that in the HC or LC groups, and no significant difference was observed between the HC and LC groups. Thus, feeding lactating goats an HC diet induces apoptosis in mammary cells, and supplementing the diet with sodium butyrate reduces the concentrations of LPS and proinflammatory cytokines, subsequently attenuating the activation of NF-kappaB and caspase-3 and eventually inhibiting apoptosis in mammary cells.

AB - A visible light-driven amine-functionalized Al-based MOF#@ yxSm2O3-ZnO nanocomposite (NH2-MOF#@ yxSm2O3-ZnO NCP) was synthesized as an effective photocatalyst for AMX degradation in the presence of ultrasound, in which # is MOF synthesis conditions from MOFI to MOFXII and x and y stand for the weight percentages of Sm2O3-to-ZnO and Sm2O3-ZnO-to-MOF, respectively. The beta-lactam antibiotic AMX, which is widely used for treating Gram-positive and Gram-negative bacterial infections in both animals and humans, was employed as a model pollutant. Using different detection techniques, the synthesized materials were characterized. Furthermore, effects of different synthesis methods, ultrasonic time, precursor concentration, sonication amplitude, and modulators on the MOFs photocatalytic behavior were taken into account. Also, catalytic dose and recycling, H2O2 usage, and operating pH effects were investigated. Compared to the pure forms of NH2-MOF-53(Al) and Sm2O3-ZnO, the NCPs having the optimal Sm2O3 ZnO and NH2-MOF-53(Al) contents highly influenced the photocatalytic activity due to the synergetic impacts of the high charge mobility and the red shift in the NH2-MOF@Sm2O3-ZnO NCPs absorption edge compared to the Sm2O3-ZnO nanoflowers. We used a TOC analyzer, UV/vis spectroscopy, and HPLC chromatogram to estimate the rate of AMX elimination in water over NH2-MOFXII@307Sm2O3-ZnO NCPs as our optimal sample. In addition, after the AMX pollutant degradation, the NH2-MOF@Sm2O3-ZnO NCPs were structurally stable and maintained the majority of their photocatalytic properties even after five runs of recycling process The NH2-MOFXII@307Sm2O3-ZnO NCPs as the superior photocatalysts were more examined and a mechanism for the AMX degradation was suggested. As a suggestion, our obtained results can be used as a starting point for the preparation of the other heterogeneous MOF-based NCPs combined with the Sm2O3-ZnO for a variety of applications such as the environmental remediation. PMID- 29446934 TI - Guanidinium-Functionalized Interpolyelectrolyte Complexes Enabling RNAi in Resistant Insect Pests. AB - RNAi-based technologies are ideal for pest control as they can provide species specificity and spare nontarget organisms. However, in some pests biological barriers prevent use of RNAi, and therefore broad application. In this study we tested the ability of a synthetic cationic polymer, poly-[ N-(3 guanidinopropyl)methacrylamide] (pGPMA), that mimics arginine-rich cell penetrating peptides to trigger RNAi in an insensitive animal- Spodoptera frugiperda. Polymer-dsRNA interpolyelectrolyte complexes (IPECs) were found to be efficiently taken up by cells, and to drive highly efficient gene knockdown. These IPECs could also trigger target gene knockdown and moderate larval mortality when fed to S. frugiperda larvae. This effect was sequence specific, which is consistent with the low toxicity we found to be associated with this polymer. A method for oral delivery of dsRNA is critical to development of RNAi based insecticides. Thus, this technology has the potential to make RNAi-based pest control useful for targeting numerous species and facilitate use of RNAi in pest management practices.

PMID- 29446937 TI - Preparation, Structure Evolution, and Metal-Insulator Transition of Na xRhO2 Crystals (0.25 <= x <= 1). AB - The triangular lattice Na xRhO2 contains a 4d Rh element with large spin-orbit coupling, and the electron-electron correlation effect is expected to have some novel physical properties. Here we report NaRhO2 crystal growth by Na2CO3 vapor growth and a series of Na xRhO2 (0.25 <= x <= 1) crystals prepared using the chemical desodiation method. Na xRhO2 reveals a layer structure with the space group R3 m, and the lattice parameter a evolves from 3.09 to 3.03 A and c from 15.54 to 15.62 A when x decreases from 1.0 to 0.2. Decreasing potassium concentration leads to a contraction of the RhO6 octahedral layers, which may be attributed to a higher covalency of Rh-O bonds. More important, the metal insulator transition in Na xRhO2 was observed in resistivity along the ab plane. The conducting mechanism of Na xRhO2 is strongly dependent on x. Two-dimensional variable range hopping (VRH) mechanisms (0.67 <= x <= 1) and metallic behaviors (0.42 and 0.47) are observed in temperature-dependent resistivity. The origin of this metal-insulator transition was discussed on the basis of the Ioffe-Regel criterion. Our work demonstrates the strong correlation between sodium concentration and physical properties of Na xRhO2.

AB - Pyrodextrin shares some properties of resistant starch, which is metabolically beneficial, and has potential applications as a functional food. In this study, we report that the oral administration of pyrodextrin (50 mg/kg/d for 7 weeks) decreased blood glucose (from 9.18 +/- 1.47 to 7.67 +/- 0.42 mmol/L), serum HbA1c, triglycerides, adipocyte size, and body weight (from 24.4 +/- 1.2 to 22.5 +/- 1.2 g) in mice with high-fat-diet-induced obesity. Western-blotting analysis suggested that pyrodextrins decreased intestinal SGLT-1 and GLUT-2 expression to ~70 and ~60% of the obese control, respectively, which slowed down glucose transportation from the gut into the blood and tentatively improved hepatic metabolism. Moreover, the pyrodextrin with a lower molecular weight of 44 kDa, a more branched structure, and increased nondigestible starch of 46.2 +/- 0.3% showed stronger hypoglycemic activity. This work provides important information for developing pyrodextrins as a functional food and dietary supplement for the management of obesity and diabetes. PMID- 29446939 TI - Particle/Gas Partitioning of Phthalates to Organic and Inorganic Airborne Particles in the Indoor Environment. AB - The particle/gas partition coefficient Kp is an important parameter affecting the fate and transport of indoor semivolatile organic compounds (SVOCs) and resulting human exposure. Unfortunately, experimental measurements of Kp exist almost exclusively for atmospheric polycyclic aromatic hydrocarbons, with very few studies focusing on SVOCs that occur in indoor environments. A specially designed tube chamber operating in the laminar flow regime was developed to measure Kp of the plasticizer di-2-ethylhexyl phthalate (DEHP) for one inorganic (ammonium sulfate) and two organic (oleic acid and squalane) particles. The values of Kp for the organic particles (0.23 +/- 0.13 m3/MUg for oleic acid and 0.11 +/- 0.10 m3/MUg for squalane) are an order of magnitude higher than those for the inorganic particles (0.011 +/- 0.004 m3/MUg), suggesting that the process by which the particles accumulate SVOCs is different. A mechanistic model based on the experimental design reveals that the presence of the particles increases the gas-phase concentration gradient in the boundary layer, resulting in enhanced mass transfer from the emission source into the air. This novel approach provides new insight into experimental designs for rapid Kp measurement and a sound basis for investigating particle-mediated mass transfer of SVOCs.

AB - Metal based therapeutics are a precious class of drugs in oncology research that include examples of theranostic drugs, which are active in both diagnostic, specifically imaging, and therapeutics applications. Ruthenium compounds have shown selective bioactivity and the ability to overcome the resistance that platinum-based therapeutics face, making them effective oncotherapeutic competitors in rational drug invention approaches. The development of antineoplastic ruthenium therapeutics is of particular interest because ruthenium containing complexes NAMI-A, KP1019, and KP1339 entered clinical trials and DW1/2 is in preclinical levels. The very robust, conformationally rigid organometallic Ru(II) compound DW1/2 is a protein kinase inhibitor and presents new Ru(II) compound designs as anticancer agents. Over the recent years, numerous strategies have been used to encapsulate Ru(II) derived compounds in a nanomaterial system, improving their targeting and delivery into neoplastic cells. A new photodynamic therapy based Ru(II) therapeutic, TLD-1433, has also entered clinical trials. Ru(II)-based compounds can also be photosensitizers for photodynamic therapy, which has proven to be an effective new, alternative, and noninvasive oncotherapy modality.

AB - We disclose a (terpy)NiBr2-catalyzed reaction protocol that regioselectively difunctionalizes unactivated olefins with tethered alkyl halides and arylzinc reagents. The reaction shows an excellent functional group tolerance (such as ketones, esters, nitriles, and halides) and a moderate to good level of diastereoselectivity. The current cyclization/cross-coupling also tolerates molecules containing base-sensitive racemizable stereocenters, which are preserved without racemization during the reaction. This cyclization/cross coupling provides a rapid access to (arylmethyl)carbo- and heterocyclic scaffolds, which occur widely as structural cores in various natural products and bioactive molecules. In order to show synthetic utility and generality, we have applied this new method in gram-scale quantities to the concise synthesis of six lignan natural products containing three different structural frameworks. We further conducted mechanistic investigations with radical probes and selectivity studies, which indicated that the current reaction proceeds via a single electron transfer (SET) process.

This protocol provides a straightforward way to synthesize a variety of useful SCF3-containing chlorides from a wide range of alkenes, including electron deficient, aromatic, and unactivated alkenes. Mechanistic studies indicate that this is a free radical transformation, and the stronger electrophilic trifluoromethylthiolating reagent CF3SCl was generated in situ under the employed conditions. The synthetic applications of this approach were also explored by a variety of synthetically useful transformations.

AB - Although there are many synthetic methods to produce fluorinated and trifluoromethylated organic structures, the construction of difluoromethylated compounds remains a synthetic challenge. We have discovered that unactivated imines will react with difluoroenolates under exceedingly mild conditions when using magnesium salts and organic bases. We have applied this approach to the iminoaldol reaction to produce difluoromethylene groups as alpha,alpha-difluoro beta-amino-carbonyl groups. This method provides synthetically useful quantities of difficult to access alpha,alpha-difluoro-beta-aminoketones without the need of protecting groups or the use of activated imines. Moreover, we have applied this strategy to create analogues of the dual orexin receptor antagonist, almorexant, in only two synthetic steps. PMID- 29446945 TI - Statistical Model To Decipher Protein Folding/Unfolding at a Local Scale. AB - Protein folding/unfolding can be analyzed experimentally at a local scale by monitoring the physical properties of local probes as a function of the temperature, for example, the distance between fluorophores or the values of chemical shifts of backbone atoms. Here, the analytical Lifson-Roig model for the helix-coil transition is modified to analyze local thermal unfolding of the fast folder W protein of bacteriophage lambda (gpW) simulated by all-atom molecular dynamics (MD) simulations in explicit solvent at 15 different temperatures. The protein structure is described by the coarse-grained dihedral angles (gamma) and bond angles (theta) built between successive Calpha-Calpha virtual bonds. Each (gamma,theta) pair serves as a local probe of protein unfolding. Local native/non native states are defined for each pair of (gamma,theta) angles by analyzing the free-energy landscapes Delta G(gamma,theta) computed from MD trajectories. The three local elementary equilibrium constants of the model are extracted for each (gamma,theta) pair along the sequence from MD simulations, and the model predictions are compared to the MD data. Using only the local equilibrium constants as an input, we show that the local denaturation curves computed from the model partition function fit their MD simulated counterparts in a satisfying manner without any adjustment. In the model and MD simulations, gpW unfolds gradually between 320 and 340 K, with an average native percentage decreasing from 0.8 (320 K) to 0.2 (340 K). In the prism of the model, there is no stable structure at the local scale in this 20 K unfolding temperature range. The enthalpy change upon local unfolding computed from the model and from MD trajectories suggests that the unfolded state between 320 and 340 K corresponds to a dynamical equilibrium between a large ensemble of constantly changing structures. The present results confirm the downhill unfolding of gpW, which does not obey a two-state global folding/unfolding model, and shed light on the interpretation of local denaturation curves.

AB - In recent years, a number of quantum mechanical-molecular mechanical (QM/MM) enzyme studies have investigated the dependence of reaction energetics on the size of the QM region using energy and free energy calculations. In this study, we revisit the question of QM region size dependence in QM/MM simulations within the context of energy and free energy calculations using a proton transfer in a DNA base pair as a test case. In the simulations, the QM region was treated with a dispersion-corrected AM1/d-PhoT Hamiltonian, which was developed to accurately describe phosphoryl and proton transfer reactions, in conjunction with an electrostatic embedding scheme using the particle-mesh Ewald summation method. With this rigorous QM/MM potential, we performed rather extensive QM/MM sampling, and found that the free energy reaction profiles converge rapidly with respect to the QM region size within ca. +/-1 kcal/mol. This finding suggests that the strategy of QM/MM simulations with reasonably sized and selected QM regions, which has been employed for over four decades, is a valid approach for modeling complex biomolecular systems. We point to possible causes for the sensitivity of the energy and free energy calculations to the size of the QM region, and potential implications.

Secondary amines like heteroaromatic amines and nucleobases have also been used, affording the corresponding coupling products in good to excellent yields.

AB - The adenosine A1 receptor (A1AR) is a potential novel therapeutic target for myocardial ischemia-reperfusion injury. However, to date, clinical translation of prototypical A1AR agonists has been hindered due to dose limiting adverse effects. Recently, we demonstrated that the biased bitopic agonist 1, consisting of an adenosine pharmacophore linked to an allosteric moiety, could stimulate cardioprotective A1AR signaling in the absence of unwanted bradycardia. Therefore, this study aimed to investigate the structure-activity relationship of compound 1 biased agonism. A series of novel derivatives of 1 were synthesized and pharmacologically profiled. Modifications were made to the orthosteric adenosine pharmacophore, linker, and allosteric 2-amino-3-benzoylthiophene pharmacophore to probe the structure-activity relationships, particularly in terms of biased signaling, as well as A1AR activity and subtype selectivity. Collectively, our findings demonstrate that the allosteric moiety, particularly the 4-(trifluoromethyl)phenyl substituent of the thiophene scaffold, is important in conferring bitopic ligand bias at the A1AR.

AB - Excitatory activity in the CNS is predominately mediated by l-glutamate through several families of l-glutamate neurotransmitter receptors. Of these, the N methyl-d-aspartate receptor (NMDAR) family has many critical roles in CNS function and in various neuropathological and psychiatric conditions. Until recently, the types of compounds available to regulate NMDAR function have been quite limited in terms of mechanism of action, subtype selectivity, and biological effect. However, several new classes of NMDAR agents have now been identified that are positive or negative allosteric modulators (PAMs and NAMs, respectively) with various patterns of NMDAR subtype selectivity. These new agents act at several newly recognized binding sites on the NMDAR complex and offer significantly greater pharmacological control over NMDAR activity than previously available agents. The purpose of this review is to summarize the structure-activity relationships for these new NMDAR modulator drug classes and to describe the current understanding of their mechanisms of action.

AB - In this work, we demonstrated that the simple substitution of the 1,2,4-triazole moiety in 5-( 4H-1,2,4-triazol-4-yl)isophthalic acid (5-TIA) by the 1 H-1,2,3 triazol-5-yl unit enables the preparation of a hydrogelator (click-TIA). In sharp contrast to 5-TIA, its isostere click-TIA undergoes self-assembly in water upon sonication, leading to the formation of stable supramolecular viscoelastic hydrogels with a critical gelation concentration of 6 g/L. Hydrogels made of click-TIA as well as hybrid hydrogels made of the mixture click-TIA + 5-TIA (molar ratio 1:0.2) were used to compare different properties of the materials (i.e., rheological properties, thermal properties, mechanical stability, morphology). In terms of toxicity, neither click-TIA nor 5-TIA showed cytotoxic effects on cellular viability of HeLa cells up to 2.3 * 10-3 g/L when compared to untreated cells incubated with DMSO. Furthermore, the hydrogels were used for the encapsulation and in vitro controlled release of oxytetracycline that followed first-order kinetics. For the hydrogel made of click-TIA, a maximum drug release of ~60% was reached after ~8 h within a pH range between 6.5 and 10. However, the release rate was reduced to approximately half of its value at pH values between 1.2 and 5.0, whereas the use of hybrid hydrogels made of click-TIA + 5-TIA allowed to reduce the original rate at pH <= 6.5.

AB - Reaction conditions allowing a stereoretentive cross-coupling of alkenyl sulfides with Grignard reagents using ligand-free Pd catalysis are discussed here. The presence of an adequately positioned OH function is a key feature that allows a Mg-promoted Lewis acid activation of the mercaptide leaving group. This easy to implement procedure actually relies on an in situ generation of stable Pd nanoparticles by simply mixing Pd2(dba)3, the Grignard reagent, and the vinyl sulfide cross-coupling partner in THF. The efficiency of this procedure has been demonstrated in a natural product total synthesis context.

PMID- 29446954 TI - Mechanism of Initial Stage of Pore Formation Induced by Antimicrobial Peptide Magainin 2. AB - Antimicrobial peptide magainin 2 forms pores in lipid bilayers, a property that is considered the main cause of its bactericidal activity. Recent data suggest that tension or stretching of the inner monolayer plays an important role in magainin 2-induced pore formation in lipid bilayers. Here, to elucidate the mechanism of magainin 2-induced pore formation, we investigated the effect on pore formation of asymmetric lipid distribution in two monolayers. First, we developed a method to prepare giant unilamellar vesicles (GUVs) composed of dioleoylphosphatidylglycerol (DOPG), dioleoylphosphatidylcholine (DOPC), and lyso PC (LPC) in the inner monolayer and of DOPG/DOPC in the outer monolayer. We consider that in these GUVs, the lipid packing in the inner monolayer was larger than that in the outer monolayer. Next, we investigated the interaction of magainin 2 with these GUVs with an asymmetric distribution of LPC using the single GUV method, and found that the rate constant of magainin 2-induced pore formation, kp, decreased with increasing LPC concentration in the inner monolayer. We constructed a quantitative model of magainin 2-induced pore formation, whereby the binding of magainin 2 to the outer monolayer of a GUV induces stretching of the inner monolayer, causing pore formation. A theoretical equation defining kp as a function of magainin 2 surface concentration, X, reasonably explains the experimental relationship between kp and X. This model quantitatively explains the effect on kp of the LPC concentration in the inner monolayer. On the basis of these results, we discuss the mechanism of the initial stage of magainin 2-induced pore formation. PMID- 29446955 TI - Modeling Gas Flow Dynamics in Metal-Organic Frameworks. AB - Modeling fluid flow dynamics in metal organic frameworks (MOFs) is a required step toward understanding mechanisms of their activity as novel catalysts, sensors, and filtration materials. We adapted a lattice Boltzmann model, previously used for studying flow dynamics in meso- and microporous media, to the nanoscale dimensions of the MOF pores. Using this model, rapid screening of permeability of a large number of MOF structures, in different crystallographic directions, is possible. The method was illustrated here on the example of an anisotropic MOF, for which we calculated permeability values in different flow directions. This method can be generalized to a large class of MOFs and used to design MOFs with the desired gas flow permeabilities.

AB - A series of pi-extended cycl[3,3,2]azines (3) bearing additional carbonyl groups were synthesized via aldol condensations. Two strong electron acceptor molecules (4 and 5), with low-lying LUMO energy levels of -3.99 and -3.95 eV, respectively, were obtained. Organic thin-film transistors (TFTs) based on the cyanated cyclazine derivatives 5 were fabricated by vapor deposition, exhibiting extraordinarily stable n-type semiconductor character under ambient condition with the highest electron mobility of 0.06 cm2 V-1 s-1 consistently for more than 30 months. PMID- 29446957 TI - Vitamin Catalysis: Direct, Photocatalytic Synthesis of Benzocoumarins via (-) Riboflavin-Mediated Electron Transfer. AB - An operationally simple protocol is disclosed to facilitate entry to benzo-3,4 coumarins directly from biaryl carboxylic acids without the need for substrate prefunctionalization. Complementary to classic lactonization strategies, this disconnection relies on the oxidation competence of photoactivated (-)-riboflavin (vitamin B2) to generate the heterocyclic core via photoinduced single electron transfer. Collectively, the inexpensive nature of the catalyst, ease of execution, and absence of external metal additives are a convincing endorsement for the incorporation of simple vitamins in contemporary catalysis. PMID- 29446958 TI - Density Functional Theory plus Hubbard U Study of the Segregation of Pt to the CeO2- x Grain Boundary. AB - Grain boundaries (GBs) can be used as traps for solute atoms and defects, and the interaction between segregants and GBs is crucial for understanding the properties of nanocrystalline materials. In this study, we have systematically investigated the Pt segregation and Pt-oxygen vacancies interaction at the ?3 (111) GB in ceria (CeO2). The Pt atom has a stronger tendency to segregate to the ?3 (111) GB than to the (111) and (110) free surfaces, but the tendency is weaker than to (112) and (100). Lattice distortion plays a dominant role in Pt segregation. At the Pt-segregated-GB (Pt@GB), oxygen vacancies prefer to form spontaneously near Pt in the GB region. However, at the pristine GB, oxygen vacancies can only form under O-poor conditions. Thus, Pt segregation to the GB promotes the formation of oxygen vacancies, and their strong interactions enhance the interfacial cohesion. We propose that GBs fabricated close to the surfaces of nanocrystalline ceria can trap Pt from inside the grains or other types of surface, resulting in the suppression of the accumulation of Pt on the surface under redox reactions, especially under O-poor conditions.

PMID- 29446960 TI - Improving adjustment and resilience in children following a disaster: Addressing research challenges. AB - There is compelling evidence of the potential negative effects of disasters on children's adjustment and functioning. Although there is an increasing base of evidence supporting the effectiveness of some interventions for trauma following disaster, more research is needed, particularly on interventions that can be delivered in the early aftermath of disaster as well as those that can address a broader range of adjustment difficulties such as bereavement that may be experienced by children after a disaster. This article identifies gaps in the knowledge of how best to intervene with children following disasters. Key challenges in conducting research in disaster contexts, including obtaining consent, designing rigorous studies, and obtaining funding quickly enough to conduct the study, are discussed. Several strategies hold promise to address research challenges in disasters, including using alternative designs (e.g., propensity scores, matched control groups, group-level assignment), working with schools and communities, and studying implementation of nontraditional modes of intervention delivery. (PsycINFO Database Record PMID- 29446961 TI - Psychopathic men: Deficits in general mental ability, not emotion perception. AB - Psychopathy is characteristically associated with deficits in emotion perception; however, findings surrounding this deficit are actually quite mixed. This is most likely due to limitations of study methodology, including the use of tasks with unknown or poor psychometric properties, underpowered samples, and a lack of control for third variables. We present a study that addressed these limitations. A sample of men (n = 339) ranging across the psychopathy continuum, recruited in and out of the German prison system, completed three psychometrically validated tasks that assessed the ability to perceive facially expressed emotions. Using latent variable modeling, we show that deficits in emotion perception ability associated with psychopathy are fully attributable to deficits in general mental ability. Modeling relations at the manifest level, separately for inmates and noninmates, support these conclusions. We conclude that emotion general and emotion-specific deficits associated with psychopathy have been exaggerated and instead indicate deficits in general mental ability. (PsycINFO Database Record PMID- 29446962 TI - Borderline personality features and integration of positive and negative thoughts about significant others. AB - Taking the bad with the good is a necessity of life, and people who readily integrate thoughts of their loved one's flaws with thoughts of their more positive attributes maintain more stable, satisfying relationships. Borderline personality disorder, however, is often characterized by interpersonal perceptions that fluctuate between extremes of good and bad. We used a timed judgment task to examine information processing about significant others in individuals high in borderline personality features relative to healthy individuals and those high in avoidant personality features. In Study 1, when judging traits of a liked significant other, same-valence facilitation by negative primes (judging negative traits faster than positive traits after a negative prime) was significantly stronger in the borderline features group than the other two groups, and was inversely associated with self-reports of integrated thoughts about significant others. In contrast, same-valence facilitation by positive primes (judging positive traits faster than negative traits after a positive prime) was significantly stronger in the avoidant features group than the other two groups, and inversely associated with self esteem. No between-group differences in same-valence facilitation were statistically significant when participants judged traits of disliked significant others, liked foods, and disliked foods. In Study 2, same-valence facilitation by negative primes when judging traits of a liked significant other was significantly associated with less integrated positive/negative thoughts about that person in a 12-day diary. These results identify an implicit information processing pattern relevant to interpersonal difficulties in borderline personality disorder. (PsycINFO Database Record PMID- 29446963 TI - The effect of data points per x- to y-axis ratio on visual analysts evaluation of single-case graphs. AB - Research based on single-case designs (SCD) are frequently utilized in educational settings to evaluate the effect of an intervention on student behavior. Visual analysis is the primary method of evaluation of SCD, despite research noting concerns regarding reliability of the procedure. Recent research suggests that characteristics of the graphic display may contribute to poor reliability and overestimation of intervention effects. This study investigated the effect of increasing or decreasing the data points per x- to y-axis ratio (DPPXYR) on rater evaluations of functional relation and effect size in SCD data sets. Twenty-nine individuals (58.6% male) with experience in SCD were asked to evaluate 40 multiple baseline data sets. Two data sets reporting null, small, moderate, and large intervention effects (8 total) were modified by manipulating the ratio of the x- to y-axis (5 variations), resulting in 40 total graphs. Results indicate that raters scored effects as larger as the DPPXYR decreased. Additionally, a 2-way within-subjects analysis of variance (ANOVA) revealed a significant main effect of DPPXYR manipulation on effect size rating, F(2.11, 58.98) = 58.05, p < .001, eta2 = .675, and an interaction between DPPXYR manipulation and magnitude of effect, F(6.71, 187.78) = 11.45, p < .001, eta2 = .29. Overall, results of the study indicate researchers and practitioners should maintain a DPPXYR of .14 or larger in the interest of more conservative effect size judgments. (PsycINFO Database Record PMID- 29446964 TI - Gender and age interact to predict the development of posttraumatic stress disorder symptoms following a motor vehicle accident. AB - OBJECTIVE: Women have a greater overall risk of developing posttraumatic stress disorder (PTSD) than men after exposure to trauma. In addition to gender, other sociodemographic factors have been identified as risk factors for PTSD; however, research has typically examined these factors separately. Age has been found to contribute to the development of psychiatric disorders, and both linear and curvilinear relationships have been reported between age and risk of developing PTSD. Recent research has suggested that this relationship may vary depending on gender. METHOD: We performed a secondary analysis of data from a prospective study of 287 (164 men, 123 women) motor vehicle accident (MVA) patients (aged 18 81) who completed clinical interviews 6 weeks, 6 months, and/or 1 year after an MVA. RESULTS: Overall, women developed more severe PTSD symptoms than men; however, gender differences were small in the young (18-24 years) and the old (55 and older) groups. In women, age was not associated with PTSD symptoms at 6 weeks and 6 months; however, age was curvilinearly associated with PTSD severity at 1 year post-MVA such that middle-aged women reported greater symptom severity than younger and older women. Prior trauma exposure and social support mediated this relationship. In men, PTSD severity was not associated with age, but was related to income and social support. CONCLUSIONS: These findings highlight age-based subgroups of women at elevated risk for PTSD following a traumatic injury and suggest that psychosocial intervention with middle-aged women following trauma exposure may help reduce the risk of persistent PTSD symptoms. (PsycINFO Database Record PMID- 29446966 TI - When divided attention fails to enhance memory encoding: The attentional boost effect is eliminated in young-old adults. AB - In the Attentional Boost Effect (ABE), images or words presented with to-be responded target squares are later recognized more accurately than images or words presented with to-be-ignored distractor squares. Surprisingly, previous studies investigating the ABE have always examined young participants: thus, the question of whether this memory facilitation can be also observed in older adults has never been tested. The present study sought to fill this gap by examining whether healthy aging modulated the size of the ABE in 4 experiments in which the nature of the background stimuli (images vs. words), the length of the encoding trials (500 vs. 1,000 ms), and the type of instructions given to participants (incidental vs. intentional) were varied. In all cases, the results showed that the ABE was robust and significant in younger adults, whereas it was completely abolished in older adults. It is suggested that the detection of target squares required more attention resources in older than in younger adults, and that these resources were subtracted from the encoding of target-associated stimuli; thus, reducing or eliminating the ABE in the older group. Alternative explanations are also discussed. (PsycINFO Database Record PMID- 29446967 TI - Perceived control and frailty: The role of affect and perceived health. AB - Mechanisms underlying prospective associations of perceived control with frailty and other health outcomes are not well understood. In the present study we used 3 waves of data from the Health and Retirement Study (N = 2,127) to test potential psychological and biological pathways linking perceived control with frailty over an 8-year period, and whether 4-year change in control predicts frailty independent of initial control. Lower odds of increasing frailty were associated with higher initial levels of perceived control (odds ratio [OR] = .74, p < .001, 95% confidence interval [CI] [.65, .83]) and a more positive change in perceived control (OR = .82, p = .006, 95% CI [.73, .92]), independent of the personality traits neuroticism and conscientiousness. In cross-lagged mediation models, the association of initial perceived control with frailty was partially mediated by positive affect, negative affect, and self-rated health, but not C-reactive protein or allostatic load. Associations of perceived control with positive and negative affect were bidirectional, with mediation in both directions. Initial frailty status was not related to 4-year change in perceived control. Perceived control may affect frailty risk through influences on affective states as well as perceived health. Findings also extend evidence that changes in perceived control may be prognostic of future health outcomes in older adults. (PsycINFO Database Record PMID- 29446965 TI - Associations between coherent neural activity in the brain's value system during antismoking messages and reductions in smoking. AB - OBJECTIVE: Worldwide, tobacco use is the leading cause of preventable death and illness. One common strategy for reducing the prevalence of cigarette smoking and other health risk behaviors is the use of graphic warning labels (GWLs). This has led to widespread interest from the perspective of health psychology in understanding the mechanisms of GWL effectiveness. Here we investigated differences in how the brain responds to negative, graphic warning label-inspired antismoking ads and neutral control ads, and we probed how this response related to future behavior. METHOD: A group of smokers (N = 45) viewed GWL-inspired and control antismoking ads while undergoing fMRI, and their smoking behavior was assessed before and one month after the scan. We examined neural coherence between two regions in the brain's valuation network, the medial prefrontal cortex (MPFC) and ventral striatum (VS). RESULTS: We found that greater neural coherence in the brain's valuation network during GWL ads (relative to control ads) preceded later smoking reduction. CONCLUSIONS: Our results suggest that the integration of information about message value may be key for message influence. Understanding how the brain responds to health messaging and relates to future behavior could ultimately contribute to the design of effective messaging campaigns, as well as more broadly to theories of message effects and persuasion across domains. (PsycINFO Database Record PMID- 29446968 TI - Aging and altruism in intertemporal choice. AB - In addition to making decisions about gains and losses that affect only ourselves, we often make decisions that affect others. Research on life span changes in motivation suggests that altruistic motives become stronger with age, but no prior research has examined how altruism affects tolerance for temporal delays. Experiment 1 used a realistic financial decision making task involving choices for gains, losses, and donations. Each decision required an intertemporal choice between a smaller-immediate and a larger-later option. Participants more often chose the larger-later option in the context of donations than in the context of losses; thus, parting with more of their overall capital when the act of doing so benefited a charity. As predicted, the magnitude of this "altruism effect" was amplified in older relative to younger adults. This pattern was replicated in a second experiment that was conducted online to minimize the influence of demand characteristics. Overall, these findings add to the literature on an age-related increase in altruism, and are the first to demonstrate its effects on intertemporal choice. (PsycINFO Database Record PMID- 29446969 TI - Age-related changes in emotional qualities of the social network from middle adulthood into old age: How do they relate to the experience of loneliness? AB - Research shows that people maintain fewer social ties and social activities when they grow older. There appears, however, to be little variation in the average loneliness level from middle adulthood into old age. In this study we investigate to what extent beneficial changes in emotional qualities of the social network (SNW; number of distressing relationships, number of pleasant relationships, relationship satisfaction) may help to prevent an age-related increase in loneliness. We concentrate in particular on the question as to whether these emotional qualities become more relevant for predicting loneliness when people grow older. Data for this study comes from 10,900 participants of the German Ageing Survey (DEAS) that have been observed over up to 9 years of study. The dynamics of emotional qualities of the SNW and loneliness are examined over a broad age range of 40 to 84 years by using an accelerated longitudinal data design. The results of our analyses suggest that age-related changes in emotional qualities of the SNW are marked by both gains and losses. On the one hand, people report fewer distressing ties and a higher satisfaction with family relations when they grow older. On the other hand, older adults are less satisfied with their friendships and acquaintances. The number of pleasant ties demonstrates little variation with age. All emotional qualities of the SNW considered in this study were found to be relevant for predicting a person's level of loneliness. Other than expected, however, predictive effects were similar over age groups. (PsycINFO Database Record PMID- 29446970 TI - Age differences in emotional responses to monetary losses and gains. AB - People of all ages face events that threaten their well-being, but theories of aging posit that older adults will cope better. In a gamble with randomly assigned losses (vs. gains), older adults reported relatively less negative and more positive emotions than younger adults, especially after losses (vs. gains). Avoiding preoccupation with negative thoughts was more likely among older (vs. younger) adults and was related to less negative emotions after losses (vs. gains). A focus on limited time was associated with more positive emotions across all participants. Our findings may inform interventions that aim to promote emotional well-being across all ages. (PsycINFO Database Record PMID- 29446971 TI - Preserved neural event segmentation in healthy older adults. AB - An important feature of action understanding is that comprehenders segment the perceptual stream into events. Event segmentation dynamically engages a network of brain regions that likely play a role in how events are encoded. Here, in a sample of older adults, we assessed the relationship between changes in brain dynamics during movie watching and event understanding performance. Forty healthy older adults and a comparison sample of 12 younger adults passively viewed short movies of everyday activities while their brain activity was measured with fMRI. Afterward, they segmented the movies into events and performed memory tasks for movie content. The older adults engaged a similar event segmentation network during movie watching as the younger adults. Individual differences analyses revealed that although behavioral measures of event segmentation predicted memory, activity in the segmentation network did not. Intersubject correlation analyses revealed that normative brain dynamics during viewing in the right posterior temporal sulcus and left dorsolateral prefrontal cortex predicted better segmentation performance. These data suggest that these regions play an important role in event understanding, and also that the event segmentation network is preserved in healthy aging.

AB - Traditionally the FHA is calculated stepwise between data points (sFHA), requiring down sampling to achieve a sufficiently large step size to minimize error. This paper proposes an alternate FHA calculation approach (rFHA), using a unique reference position to reduce error associated with small rotation angles. This study demonstrated error reduction using the rFHA approach relative to the sFHA approach. Furthermore, the rFHA in the femur is defined at each time point providing a continuous representation of joint motion. These characteristics enable the rFHA to quantify small differences in knee joint motion, providing an excellent measure to quantify knee joint stability. PMID- 29446975 TI - Primary adrenal insufficiency due to hereditary apolipoprotein AI amyloidosis: endocrine involvement beyond hypogonadism. AB - Several mutations in the gene encoding apolipoprotein AI (apoAI) have been described as a cause of familial amyloidosis. Individuals with apoAI-derived (AApoAI) amyloidosis frequently manifest with liver, kidney, laryngeal, skin and myocardial involvement. Although primary hypogonadism (PH) is considered almost pathognomonic of this disease, until now, primary adrenal insufficiency (PAI) has not been described as a common clinical feature. Here, we report the first kindred with AApoAI amyloidosis in which PAI is well-documented. All family members with the Leu60_Phe71delins60Val_61Thr heterozygous mutation who were regularly followed-up at our centre were considered. Nineteen individuals had the confirmed APOA1 deletion/insertion mutation, with detailed medical records available in 11 cases. Of these, 6 had PAI and 3 (all males) had PH. Among them, one 47-year-old man, not previously diagnosed with PAI, developed adrenal crisis after liver transplantation, precipitated by an opportunistic infection. Transplantation due to organ failure, which necessitates use of immunosuppressive medication such as corticosteroids, is frequently required during the course of hereditary amyloidosis. Consequently, PAI can remain masked, being discovered only when an adrenal crisis develops. Therefore, according to the present evidence, patients with AApoAI amyloidosis should be submitted to regular testing of corticotrophin and cortisol levels in order to avoid delaying corticosteroid replacement.

PMID- 29446977 TI - Establishment, Growth, Proliferation, and Gene Expression of Buffalo (Bubalus bubalis) Transgenic Fetal Fibroblasts Containing Human Insulin Gene, and Production of Embryos by Handmade Cloning Using These Cells. AB - The aim of the present study was to compare transgenic cells, containing human insulin gene kept under the control of mammary gland-specific buffalo beta lactoglobulin promoter, and their counterparts, that is, nontransgenic cells, for examining their potential for the production of embryos following somatic cell nuclear transfer (SCNT). The gene construct was delivered into buffalo fetal fibroblasts (BFF) by nucleofection following which, the transfected cells were selected by culture in the presence of G418 for 3 weeks. Transgene integration into BFF genome was confirmed by polymerase chain reaction (PCR) and reverse transcriptase PCR. At passage 8-10, the growth rate, cell proliferation rate, and quantitative expression of certain genes were compared between transgenic and nontransgenic cells. The growth rate and cell proliferation rate was significantly lower (p < 0.05) for transgenic than for nontransgenic cells. Using quantitative real-time PCR it was found that the expression level of CASPASE 3, CASPASE 9, BAX, and P53 was significantly higher (p < 0.05) and that of HDAC1 and IGF-1R was significantly lower (p < 0.05) in transgenic compared with nontransgenic cells. The differences in the relative expression level of BCL-XL, MCL-1, DNMT1, DNMT3a, GDF9, FGF2, and G6PD between the two groups were not significant. Furthermore, when the two cell types were used as donor cells for production of embryos by handmade cloning, the blastocyst rate was significantly lower (p < 0.05) with transgenic (35.69% +/- 1.78%) than with nontransgenic cells (48.75% +/- 2.38%). In conclusion, these results indicate that differences were present between transgenic and nontransgenic cells, which may affect the efficiency of SCNT when used as donor cells.

AB - INTRODUCTION: Synovial sarcoma is a rare mesenchymal malignant neoplasm that accounts for less than 10% of soft tissue sarcomas. About 95% of the sarcomas occur in the extremities. Primary synovial sarcomas of the spine are a rare tumor arising from the paravertebral regions, paraspinal muscles or epidural spaces. PURPOSE: To report an atypical radiological presentation of synovial sarcoma of the thoracic spine mimicking a nerve sheath tumor in an elderly adult and describe the management with review of the literature. CLINICAL PRESENTATION: A forty-six-year-old lady presented with clinical features of a thoracic intradural extramedullary cord compression at T7 level. She was Nurick grade 4 at presentation. MRI of the Thoracic spine with whole spine screening showed a contrast enhancing intradural extramedullary tumor at the T7-8 level; the tumor was exiting out through the left T7-8 neural foramina with foraminal widening. The possibility of a schwannoma was considered. INTERVENTION: She underwent a T7 8 laminectomy and total excision of the tumor followed by posterior fusion. The biopsy was reported as synovial sarcoma. She subsequently underwent radiation and chemotherapy. She had marked improvement in her Neurological status and remained disease free at six months follow-up. CONCLUSION: Synovial sarcoma of the spine is a rare mesenchymal malignant neoplasm. One needs to consider Synovial sarcoma as one of the differential diagnosis of intradural tumors of the spine. PMID- 29446980 TI - Best Use of Models to Advance the Artificial Pancreas.

AB - Current treatments of oesophageal diseases, such as carcinoma, congenital abnormality or trauma, require surgical intervention and oesophageal reconstruction with the stomach, jejunum or colon. However, serious side effects are possible with each treatment option. Despite tissue engineering promising to be an effective regenerative strategy, no functional solution currently exists for oesophageal reconstruction. Here, we developed an omentum-cultured oesophageal scaffold reinforced by a 3D-printed ring. The nano-structured scaffolds were wrapped into the omentum of rats and orthotopically transplanted for the repair of circumferential oesophageal defects two weeks later. The artificial oesophagus exhibited complete healing of the surgically created circumferential defects by the second week. The integration of the omentum cultured oesophageal scaffold and the regenerative tissue remained intact. Macroscopically, there was no evidence of a fistula, perforation, abscess formation or surrounding soft-tissue necrosis. The omentum-cultured nano structure scaffold reinforced by a 3D-printed ring is a more practical model with better vascularization for artificial neo-oesophagus reconstruction in a rat model. PMID- 29446981 TI - Diet Pattern and Respiratory Morbidity in the Atherosclerosis Risk in Communities Study. AB - RATIONALE: Dietary intake is a potential risk factor for respiratory morbidity in adult populations. Few studies capture the effect of dietary patterns, representative of the combination of nutrients consumed, on self-reported respiratory morbidity in combination with objective measures of lung function. OBJECTIVES: To evaluate patterns of dietary intake in relation to respiratory morbidity and objective measures of lung function in a U.S. POPULATION: METHODS: The ARIC (Atherosclerosis Risk in Communities) study investigators enrolled 15,792 participants from four U.S. communities between 1987 and 1989 and collected data using a validated food frequency questionnaire to assess diet. Principal component analysis was applied, and patterns representative of "Western" and "Prudent" diets emerged. We investigated cross-sectional associations between dietary patterns and pulmonary assessments that included asthma and chronic obstructive pulmonary disease (COPD) diagnosis, respiratory symptoms, and lung function. Multivariable Poisson regression models included quintiles of dietary patterns and potential confounders. Interaction of dietary patterns with obesity, sex, and smoking status was assessed in relation to all outcomes. RESULTS: Higher scores in the "Western" dietary pattern (quintile 5 vs. quintile 1) were associated with higher prevalence of COPD (prevalence ratio [PR], 1.62; 95% confidence ratio [CI], 1.33-1.97), wheeze (PR, 1.37; 95% CI, 1.11 1.69), cough (PR, 1.32; 95% CI, 1.32-1.59), and phlegm (PR, 1.27; 95% CI, 1.05 1.54) and lower percent predicted forced expiratory volume in 1 second (FEV1), percent predicted forced vital capacity (FVC), and FEV1/FVC ratio. Higher scores in the "Prudent" dietary pattern (quintile 5 vs. quintile 1) were associated with lower prevalence of COPD (PR, 0.82; 95% CI, 0.70-0.95) and cough (PR, 0.77; 95% CI, 0.67-0.89) and higher percent predicted FEV1 and FEV1/FVC ratio. The prevalence of asthma was not related to dietary intake. CONCLUSIONS: A "Western" dietary pattern was associated with respiratory symptoms, lower lung function, and COPD in ARIC participants.

AB - In the last decade, many works in combinatorial optimisation have shown that, due to the advances in multi-objective optimisation, the algorithms from this field could be used for solving single-objective problems as well. In this sense, a number of papers have proposed multi-objectivising single-objective problems in order to use multi-objective algorithms in their optimisation. In this article, we follow up this idea by presenting a methodology for multi-objectivising combinatorial optimisation problems based on elementary landscape decompositions of their objective function. Under this framework, each of the elementary landscapes obtained from the decomposition is considered as an independent objective function to optimise. In order to illustrate this general methodology, we consider four problems from different domains: the quadratic assignment problem and the linear ordering problem (permutation domain), the 0-1 unconstrained quadratic optimisation problem (binary domain), and the frequency assignment problem (integer domain). We implemented two widely known multi objective algorithms, NSGA-II and SPEA2, and compared their performance with that of a single-objective GA. The experiments conducted on a large benchmark of instances of the four problems show that the multi-objective algorithms clearly outperform the single-objective approaches. Furthermore, a discussion on the results suggests that the multi-objective space generated by this decomposition enhances the exploration ability, thus permitting NSGA-II and SPEA2 to obtain better results in the majority of the tested instances. PMID- 29446984 TI - Anticancer Drugs as Antibiofilm Agents in Candida albicans: Potential Targets. AB - The human pathogen Candida albicans can grow as a biofilm on host tissues and on the surfaces of different prosthetic devices in a patient's body. Various studies have reported that biofilms formed by C. albicans are resistant to most of the currently used antibiotics including the widely prescribed drug, fluconazole. As such, novel strategies for the treatment of drug-resistant biofilms are required. Drug repositioning or the use of drugs outside their unique indication has the potential to radically change drug development. We have tested 16 anticancer drugs for their activities against C. albicans. For the first time, we are reporting repositioning of anticancer drugs as potential antibiofilm agents in C. albicans. Nine categories of drugs with different chemical modes of action effectively inhibited biofilms at a concentration range of 0.25-4 mg/mL, establishing their potential for the inhibition of biofilms. Human genes targeted by these drugs show significant identity with their homologous genes in C. albicans at the amino acid as well as nucleotide levels. This study indicates that anticancer drugs could be potential candidates for repositioning as anti Candida biofilm agents.

AB - We used pore water samplers (PWS) to sample for isotope analysis (1) only water, (2) soil under laboratory conditions, and (3) soil in the field comparing the results with cryogenic extraction (CE). In (1) and (2), no significant differences between source and water extracted with PWS were detected with a mean absolute difference (MAD) always lower than 2 0/00 for delta2H and 1 0/00 for delta18O. In (2), CE water was more enriched than PWS-extracted water, with a MAD respect to source water of roughly 8 0/00 for delta2H and 4 0/00 for delta18O. In (3), PWS water was enriched relative to CE water by 3 0/00 for delta2H and 0.9 0/00 for delta18O. The latter result may be due to the distinct water portions sampled by the two methods. Large pores, easily sampled by PWS, likely retain recent, and enriched, summer precipitation while small pores, only sampled by CE, possibly retain isotopically depleted water from previous winter precipitation or irrigation inputs. Accuracy and precision were greater for PWS relative to CE. PWS is therefore suggested as viable tool to extract soil water for stable isotope analysis, particularly for soils used in this study (sandy and silty loams). PMID- 29446986 TI - An Intercenter Comparison of Nasolabial Appearance Including a Center Using Nasoalveolar Molding. AB - OBJECTIVE: To compare nasolabial appearance outcomes of patients with complete unilateral cleft lip and palate (CUCLP) in preadolescence from 4 cleft centers including a center using nasoalveolar molding (NAM) and primary nasal reconstruction. DESIGN: Retrospective cohort study. SETTING: Four cleft centers in North America. PATIENTS: 135 subjects with repaired CUCLP. METHODS: Frontal and profile facial pictures were assessed using the Asher-McDade rating scale. Intra- and interrater reliability were tested using weighted Kappa statistics. Median scores by center were compared with Kruskal-Wallis statistics. RESULTS: Intrarater reliability scores were moderate to good. Interrater reliability scores were moderate. Significant differences ( P < .05) among centers were found. For nasal form, center G (median = 2.83) had better scores than centers C and D (C median = 3.33, D median = 3.17). For nose symmetry, center G had better scores (median = 2.33) than all other centers (B median = 2.67, C median = 2.83, D median = 2.83). For vermillion border, center G had better scores (median = 2.58) than centers B and C (B median = 3.17, C median = 3.17). For nasolabial profile, center G (median score = 2.67) had better scores than center C (median = 3.00). For total nasolabial score, center G (median = 2.67) had better scores than all other centers (B median = 2.83, C median = 3, D median = 2.83). CONCLUSION: The protocol followed by center G, the only center that performed NAM and primary nasal reconstruction, produced better results in all categories when compared to center C, the only center that did not perform presurgical orthopedics or lip/nose revisions. When compared to centers that performed traditional presurgical orthopedics and surgical revisions (B and D), center G was not consistently better in all categories. As with other uncontrolled, retrospective intercenter studies, it is not possible to attribute the outcomes to a specific protocol component. PMID- 29446987 TI - Dexmedetomidine Decreases Postoperative Pain and Narcotic Use in Children Undergoing Alveolar Bone Graft Surgery. AB - OBJECTIVE: Dexmedetomidine is a parenteral agent that combines the benefits of cooperative sedation, anxiolysis, and analgesia without the risks of respiratory depression. Off-label use has been reported in children. We have introduced dexmedetomidine for use in patients having undergone alveolar bone graft (ABG). The objective is to demonstrate the value and safety of postoperative dexmedetomidine infusion in a non-ICU setting following ABG. DESIGN: A retrospective review was performed on patients who underwent ABG by the senior author. Patients were divided into 2 groups: those who received postoperative dexmedetomidine and those who received patient-controlled anesthesia. MAIN OUTCOME MEASURE(S): The primary study outcome measures included patient demographics, adverse events, length of stay, pain scores, and doses of narcotics during admission were collected. RESULTS: Inclusion criteria were met by 54 patients; 39 received dexmedetomidine whereas 15 did not. There were no significant differences between groups in age, gender, and length of stay. The patients who received dexmedetomidine used oral narcotics less often ( P = .01). In addition, more patients reported no pain after surgery ( P = .05) and at the time of discharge if they received dexmedetomidine ( P < .01). There were no reported adverse effects. CONCLUSIONS: Dexmedetomidine provided superior pain control after surgery and at the time of discharge, as well as a significant decrease in the use of oral narcotics. In our institution, it has since replaced the PCA as a postoperative pain control modality. Absent the risk for respiratory depression, dexmedetomidine has demonstrated a safe option for postoperative pain control in our focused group of pediatric patients. PMID- 29446988 TI - Diagnosing Tongue Base Obstruction in Pierre Robin Sequence Infants: Sleep vs Awake Endoscopy. AB - OBJECTIVE: To investigate whether awake endoscopy can diagnose base-of-tongue obstruction as reliably as sleep endoscopy in infants with Pierre Robin sequence (PRS). DESIGN: The study was retrospective with the clinicians blinded to patient identity. Endoscopy findings were assessed and measured by the performing pediatric otolaryngologist. SETTING: Tertiary care children's hospital. PATIENTS: All infants with PRS managed between January 2005 and July 2015 were included. There were 141 patients, of which 35 underwent both awake endoscopy (AE) and drug induced sleep endoscopy (DISE). INTERVENTIONS: Bedside AE and DISE in the operating room. MAIN OUTCOME MEASURES: Presence of moderate or severe base-of tongue collapse was assessed. Sensitivity, specificity, and positive likelihood ratio of AE findings as well as intertest differences between AE and DISE were calculated. RESULTS: AE had 50.0% sensitivity (95% confidence interval [CI] 27.2% 72.8%) and 86.7% specificity (95% CI 59.5%-98.3%) for detecting base-of-tongue obstruction compared to DISE; false negative rate was 50.0% (n = 10). Positive likelihood ratio was 3.75 (CI 0.96-14.65). Compared to AE, DISE demonstrated significantly more cases of base-of-tongue obstruction ( P = .039). CONCLUSIONS: Bedside AE has low sensitivity for detecting base-of-tongue collapse in infants with PRS. Because of the substantial false negative rate, AE may not be a reliable diagnostic modality for ruling out base-of-tongue obstruction in this susceptible population. DISE may be indicated in high-risk patients to avoid underdiagnosing upper airway obstruction. PMID- 29446989 TI - Comparison of the efficacy of two human fibrinogen concentrates to treat dilutional coagulopathy in vitro. AB - Both congenital and acquired fibrinogen deficiency can be safely treated with administration of fibrinogen concentrate. The aim of this study was to test the efficacy of a new fibrinogen product (Fibryga) compared to a licensed product (Haemocomplettan) in an in vitro model of dilutional coagulopathy. Ten blood specimens from healthy volunteers were diluted 1:1 with balanced crystalloid solution and subsequently supplemented with each fibrinogen concentrate at a dose replicating in vivo supplementation (50 mg kg-1). Changes in clot firmness (FIBTEM and EXTEM assay), as well as changes in the fibrinogen antigen level, fibrinogen activity, factor XIII level and fibronectin levels were assessed at baseline, after dilution and after adding fibrinogen concentrate. There was no significant difference between the drugs in their in vitro ability to improve clot firmness in the FIBTEM assay (Fibryga: mean MCF 14.4 mm (SD 3.4 mm) vs. Haemocomplettan: MCF 14.1 mm (2.4); p = .584). Fibryga led to significantly higher clot firmness in EXTEM MCF: 56.7 mm (3.8) vs. 53.7 mm (3.7); p < .001). Distinct differences between FXIII levels (significantly higher in Fibryga; mean 40.9% (6.2%) vs. 31.0% (6.2%); p < .001) and fibronectin levels (significantly higher in Haemocomplettan; mean 0.008 g L-1 (SD 0.002 g L-1) vs. 0.002 g L-1 (SD 0.002 g L-1; p < .001) were observed between products. This is the first study to demonstrate that Fibryga and Haemocomplettan have similar efficacy in improving clot firmness in a dilutional hypofibrinogenemia model in vitro. PMID- 29446990 TI - Rapid increases in nitrogen oxides are associated with acute myocardial infarction: A case-crossover study. AB - Aims High concentrations of air pollutants are associated with increased risk for myocardial infarction. The European Union has defined statutory limits for air pollutants based on upper absolute concentrations. We evaluated the association between rapid changes in air pollutants and the risk of myocardial infarction independently of absolute concentrations. Methods and results Using a hospital based case-crossover study, effects of 24h changes of nitrogen oxides (NOX/2), particulate matter (PM10), and ozone on the risk of myocardial infarction was assessed in 693 patients. In the overall population, increases of NOX of more than 20 ug/m3 within 24 h were associated with an increase in the risk of myocardial infarction by up to 121% (odds ratio (OR) 2.21, 95% confidence interval (CI) 1.19-4.08). Comparably, rapid increases of NO2 of more than 8 ug/m3 tended to increase myocardial infarction risk by 73% (OR 1.73, 95% CI 0.91-3.28) while myocardial infarction risk decreased by 60% after a decrease of NO2 concentration of more than 8 ug/m3 (OR 0.4, 95% CI 0.21-0.77), suggesting a close to-linear association. While results for ozone concentrations were ambiguous, rapid change in PM10 was not associated with myocardial infarction risk. Conclusion Dynamics and extent of increase in nitrogen oxide concentrations may be an independent risk factor for myocardial infarction. As there are currently no European Union statutory limits reflecting this dynamic variation of air pollutants on a daily basis, the results urgently call for confirming studies in different geographical regions to verify the observations. PMID- 29446992 TI - Anticandidal activity of bioinspired ZnO NPs: effect on growth, cell morphology and key virulence attributes of Candida species. AB - The pathogenicity of Candida species in human is dependent on a variety of virulence factor such as adhesion factors, germ tube and hyphal formation, secretion of hydrolytic phospholipases and proteinases and drug resistance biofilm. ZnO NPs have been synthesized by using leaf extract of Crinum latifolium and were characterized by UV-Vis spectrophotometer, FTIR, SEM, EDX and TEM. In this study for the first time, potent inhibitory effects of ZnO NPs on principal virulence factors of Candida albicans and non-albicans such as germ tube formation, secretion of hydrolytic phospholipases and proteinases and biofilm formation has been investigated. ZnO NPs remarkably reduced the germ tube formation of C. albicans at 1 (86.4%), 0.5 (75.0%), 0.25 (61.4%), 0.125 (34.1%) and 0.062 mg/ml (11.4%). ZnO NPs significantly lowered the phospholipase and proteinase secretion by 58.8 and 95.2% at 0.25 mg/ml, respectively. CSLM results showed that ZnO NPs suppressed biofilm formation up to 85% at 0.25 mg/ml. SEM and TEM micrograph showed that ZnO NPs penetrated inside the cell and causes extensive damaged in cell wall and cell membrane. Inhibition of Candida growth and various virulent factors by ZnO NPs provides an insight towards their therapeutic application for the treatment of Candida-associated infections. PMID- 29446991 TI - Fluid-structure interaction modeling of aneurysmal arteries under steady-state and pulsatile blood flow: a stability analysis. AB - Tortuous aneurysmal arteries are often associated with a higher risk of rupture but the mechanism remains unclear. The goal of this study was to analyze the buckling and post-buckling behaviors of aneurysmal arteries under pulsatile flow. To accomplish this goal, we analyzed the buckling behavior of model carotid and abdominal aorta with aneurysms by utilizing fluid-structure interaction (FSI) method with realistic waveforms boundary conditions. FSI simulations were done under steady-state and pulsatile flow for normal (1.5) and reduced (1.3) axial stretch ratios to investigate the influence of aneurysm, pulsatile lumen pressure and axial tension on stability. Our results indicated that aneurysmal artery buckled at the critical buckling pressure and its deflection nonlinearly increased with increasing lumen pressure. Buckling elevates the peak stress (up to 118%). The maximum aneurysm wall stress at pulsatile FSI flow was (29%) higher than under static pressure at the peak lumen pressure of 130 mmHg. Buckling results show an increase in lumen shear stress at the inner side of the maximum deflection. Vortex flow was dramatically enlarged with increasing lumen pressure and artery diameter. Aneurysmal arteries are more susceptible than normal arteries to mechanical instability which causes high stresses in the aneurysm wall that could lead to aneurysm rupture. PMID- 29446993 TI - Pre-Intensive Care Unit Cognitive Status, Subsequent Disability, and New Nursing Home Admission among Critically Ill Older Adults. AB - RATIONALE: Cognitive impairment is common among older adults, yet little is known about the association of pre-intensive care unit cognitive status with outcomes relevant to older adults maintaining independence after a critical illness. OBJECTIVES: To evaluate whether pre-intensive care unit cognitive status is associated with post-intensive care unit disability, new nursing home admission, and mortality after a critical illness among older adults. METHODS: In this prospective cohort study, 754 persons aged 70 years or more were monitored from March 1998 to December 2013 with monthly assessments of disability. Cognitive status was assessed every 18 months, using the Mini-Mental State Examination (range, 0-30), with scores classified as 28 or higher (cognitively intact), 24-27 (minimal impairment), and less than 24 (moderate impairment). The primary outcome was disability count (range, 0-13), assessed monthly over 6 months after an intensive care unit stay. The secondary outcomes were incident nursing home admission and time to death after intensive care unit admission. The analytic sample included 391 intensive care unit admissions. RESULTS: The mean age was 83.5 years. The prevalence of moderate impairment, minimal impairment, and intact cognition (the comparison group) was 17.3, 46.2, and 36.5%, respectively. In the multivariable analysis, moderate impairment was associated with nearly a 20% increase in disability over the 6-month follow-up period (adjusted relative risk, 1.19; 95% confidence interval, 1.04-1.36), and minimal impairment was associated with a 16% increase in post-intensive care unit disability (adjusted relative risk, 1.16; 95% confidence interval, 1.02-1.32). Moderate impairment was associated with more than double the likelihood of a new nursing home admission (adjusted odds ratio, 2.37; 95% confidence interval, 1.01-5.55). Survival differed significantly across the three cognitive groups (log-rank P = 0.002), but neither moderate impairment (adjusted hazard ratio, 1.19; 95% confidence interval, 0.65-2.19) nor minimal impairment (adjusted hazard ratio, 1.00; 95% confidence interval, 0.61-1.62) was significantly associated with mortality in the multivariable analysis. CONCLUSIONS: Among older adults, any impairment (even minimal) in pre-intensive care unit cognitive status was associated with an increase in post-intensive care unit disability over the 6 months after a critical illness; moderate cognitive impairment doubled the likelihood of a new nursing home admission. Pre-intensive care unit cognitive impairment was not associated with mortality from intensive care unit admission through 6 months of follow-up. Pre-intensive care unit cognitive status may provide prognostic information about the likelihood of older adults maintaining independence after a critical illness.

PMID- 29446994 TI - "It's Better in a Group Anyway": Patient Experiences of Group and Individual Acupuncture. AB - OBJECTIVES: Chronic pain is prevalent, burdensome, and costly, and there are ethnic and racial disparities in treatment. Acupuncture is effective and safe, but access is limited. Group acupuncture can decrease cost and increase capacity by decreasing clinic space needs and increasing patient volume per acupuncturist; however, the effectiveness and patient acceptability of group and individual session acupuncture have never been directly compared. DESIGN: The Acupuncture Approaches to Decrease Disparities in Pain Treatment (AADDOPT-2) study is a randomized comparative effectiveness trial of acupuncture for chronic pain. Semistructured in-depth interviews were conducted with a subset of patients enrolled in the trial. SETTINGS/LOCATION: Outpatient clinics in an urban, low income area serving a primarily black and Hispanic population. SUBJECTS: Qualitative interviews were conducted with 46 patients; 23 in each arm of the AADDOPT-2 study. INTERVENTIONS: Patients were randomized to receive either individual acupuncture or acupuncture delivered in a small group. OUTCOME MEASURES: Transcripts of the interviews were analyzed using an inductive thematic framework to explore and compare the patient experience in group and individual settings. RESULTS: Patients in both study arms valued the pain relief, improved quality of life, and relaxation experienced during acupuncture. Privacy and mixed sex groups were cited as a concern by a minority of patients; however, most of those randomized to the group setting noted that these concerns abated after initiating treatment. Differences between arms included the depth of the relationship with the acupuncturist and misgivings related to the treatment space. Group dynamics varied; some groups fostered a supportive, therapeutic interaction, while others were more reserved. CONCLUSIONS: Patients in both arms valued their acupuncture experience. Participants described both positive and negative aspects of the group setting. PMID- 29446996 TI - Recent Advances in Therapeutic Genome Editing in China. AB - Editing of the genome to correct disease-causing mutations is a promising approach for the treatment of human diseases. Recent advances in the development of programmable nuclease-based genome editing tools have substantially improved the ability to make precise changes in the human genome. Genome editing technologies are already being used to correct genetic mutations in affected tissues and cells to treat diseases that are refractory to traditional gene therapies. Chinese scientists have made remarkable breakthroughs in the field of therapeutic genome editing, particularly with the first clinical trial involving the clustered regularly interspaced short palindromic repeats-caspase 9 system that began in China. Herein, current progress toward developing programmable nuclease-based gene therapies is introduced, as well as future prospects and challenges in China. PMID- 29446997 TI - Double-Dose Adenovirus-Mediated Adjuvant Gene Therapy Improves Liver Transplantation Outcomes in Patients with Advanced Hepatocellular Carcinoma. AB - The present clinical trial assessed the effect of double-dose administration of replication-deficient adenovirus-thymidine kinase and ganciclovir (ADV-TK/GCV) in patients with advanced hepatocellular carcinoma (HCC) who underwent liver transplantation (LT). Eighty-six patients with single tumor diameters >5 cm or multiple tumors with diameters >3 cm each, regardless of vascular invasion, were examined over a follow-up period of 61 months. All patients underwent orthotopic LT; 43 received LT only, and 43 received LT plus double-dose ADV-TK/GCV gene therapy (LT + ADV-TK/GCV). Recurrence-free survival (RFS) and overall survival (OS) rates, as well as therapeutic safety, were assessed. The RFS and OS rates in LT + ADV-TK/GCV patients at 3 years (55.9% and 60.3%, respectively) were significantly higher than those in the LT-only group (13.5% and 19.3%, respectively; p < 0.001). LT + ADV-TK/GCV patients without vascular invasion showed significant improvement in RFS (73.7%) and OS (68.6%). LT + ADV-TK/GCV patients without extrahepatic vascular invasion experienced higher OS versus LT only patients. Double-dose ADV-TK/GCV gene therapy combined with LT was safe and improved RFS and OS in advanced HCC patients without vascular invasion over the 5 year follow-up period. The potential to select patients with intrahepatic and extrahepatic vascular invasion for LT requires further confirmation.

PMID- 29447000 TI - Ghrelin prevents cardiac cell apoptosis during cardiac remodelling post experimentally induced myocardial infarction in rats via activation of Raf-MEK1/2 ERK1/2 signalling. AB - CONTEXT: Mechanisms by which ghrelin affords its cardioprotection in mammals remained unclear. OBJECTIVE: To examine if ghrelin confers cardio-protection during cardiac remodelling post-MI by modulating the RAF-1-MEK1/2-ERK1/2 signalling pathway. MATERIALS AND METHODS: Rats were divided into control, sham, sham + ghrelin, myocardial infarction (MI), and MI + ghrelin groups. Ghrelin (100 ug/kg) was administered for 21 days, starting one-day post-MI. RESULTS: Ghrelin enhanced cardiac contractility and the activities of antioxidant enzymes, lowered serum levels of enzyme markers of cardiac dysfunction, and lowered inflammatory mediator levels. Ghrelin increased levels of phospho-Raf-1 (Ser338), phospho MEK1/2 (Ser217/221), phospho-ERK1/2 (Thr202/Tyr204), and of their downstream target p-BAD (Ser112) and inhibited the cleavage of caspase-3. Concomitantly, ghrelin prevented the increases in the levels of fibrotic markers, including alpha-smooth muscle actin (alpha-SMA), metalloproteinase-9 (MPP-9), and type III collagen. CONCLUSION: Post-MI in rats, ghrelin stimulated Raf-1-MEK1/2-ERK1/2-BAD signalling in the LV infarct areas, accounting for its anti-apoptotic effect, enhancing cardiac function, and inhibiting cardiac fibrosis during cardiac remodelling.

PMID- 29447002 TI - Recent treatment modalities for cardiovascular diseases with a focus on stem cells, aptamers, exosomes and nanomedicine. AB - Cardiovascular diseases (CVDs) are the leading cause of morbidity and mortality worldwide. Due to the significant impact of CVD on humans, there is a need to develop novel treatment modalities tailored to major classes of cardiac diseases including hypertension, coronary artery disease, cardiomyopathies, arrhythmias, valvular disease and inflammatory diseases. In this article, we discuss recent advancements regarding development of therapeutic strategies based on stem cells, aptamers, exosomes, drug-eluting and dissolvable stents, immunotherapy and nanomedicine for the treatment of CVD. We summarize current research and clinical advances in cardiovascular therapeutics, with a focus on therapies that move beyond current oral- or sublingual-based regimens. This review article provides insight into current research and future treatment strategies that hold a great relevance for future clinical practice in pursuit of improving quality of life of patients suffering from CVD. PMID- 29447003 TI - A study on the genetic polymorphisms of CYP3A5 among the Orang Asli in Malaysia using a next generation sequencing platform. AB - BACKGROUND: CYP3A5 is the predominant sub-family of biotransformation enzymes in the liver and the genetic variations in CYP3A5 are an important determinant of inter-individual and inter-ethnic differences in CYP3A-mediated drug disposition and response. AIM: This study aims to investigate the genetic polymorphisms of CYP3A5 among the Orang Asli in Peninsular Malaysia using a next generation sequencing platform. METHODS: Genomic DNAs were extracted from blood samples of the three main Orang Asli tribes and whole-genome sequencing was performed. RESULTS: A total of 61 single nucleotide polymorphisms were identified and all the SNPs were located in introns except rs15524, which is in the 3'UTR, and 11 of these polymorphisms were novel. Two allelic variants and three genotypes were identified in the Orang Asli. The major allelic variant was the non-functional CYP3A5*3 (66.4%). The percentages of Orang Asli with CYP3A5*3/*3 (47.2%) and CYP3A5*1/*3 (38.1%) genotypes are more than twice the percentage of Orang Asli with CYP3A5*1/*1 (14.8%) genotype. Almost half of the Orang Asli harboured CYP3A5 non-expressor genotype (CYP3A5*3/*3). CONCLUSIONS: The predominance of the CYP3A5 non-expressor genotype among the Orang Asli was unravelled and the findings in this study may serve as a guide for the optimisation of pharmacotherapy for the Orang Asli community. PMID- 29447004 TI - Household food security, and social support as protective factors. PMID- 29447005 TI - Human ASIC1a mediates stronger acid-induced responses as compared with mouse ASIC1a. AB - Acid-sensing ion channels (ASICs) are the major proton receptor in the brain and a key mediator of acidosis-induced neuronal injuries in disease. Most of published data on ASIC function came from studies performed in mice, and relatively little is known about potential differences between human and mouse ASICs (hASIC and mASIC, respectively). This information is critical for us to better interpret the functional importance of ASICs in human disease. Here, we examined the expression of ASICs in acutely resected human cortical tissue. Compared with mouse cortex, human cortical tissue showed a similar ratio of ASIC1a:ASIC2a expression, had reduced ASIC2b level, and exhibited a higher membrane:total ratio of ASIC1a. We further investigated the mechanism for higher surface trafficking of hASIC1a in heterologous cells. A single amino acid at position 285 was critical for increased N-glycosylation and surface expression of hASIC1a. Consistent with the changes in trafficking and current, cells expressing hASIC1a or mASIC1a S285P mutant had a higher acid-activated calcium increase and exhibited worsened acidotoxicity. These data suggest that ASICs are likely to have a larger impact on acidosis-induced neuronal injuries in humans than mice, and this effect is, at least in part, a result of more efficient trafficking of hASIC1a.-Xu, Y., Jiang, Y.-Q., Li, C., He, M., Rusyniak, W.

PMID- 29447006 TI - Retinoic acid signaling promotes the cytoskeletal rearrangement of embryonic epicardial cells. AB - All- trans-retinoic acid (RA), a vitamin A metabolite, is an important signaling molecule required for the proper development of the heart. The epicardium is the main source of RA in the embryonic heart, yet the cardiogenic functions of epicardial-produced RA are not fully understood. Here, we investigated the roles of RA signaling in the embryonic epicardium using in vivo and in vitro models of excess or deficiency of RA. Our results suggested that RA signaling facilitates the cytoskeletal rearrangement required for the epicardial-to-mesenchymal transition of epicardial cells. In vivo treatment with an inhibitor of RA synthesis delayed the migration of epicardial-derived precursor cells (EPDCs) into the myocardium; the opposite was seen in the case of dehydrogenase/reductase superfamily (DHRS)3-deficient embryos, a mouse model of RA excess. Analysis of the behavior of epicardial cells exposed to RA receptor agonists or inhibitors of RA synthesis in vitro revealed that appropriate levels of RA are important in orchestrating the platelet-derived growth factor-induced loss of epithelial character, cytoskeletal remodeling, and migration, necessary for the infiltration of the myocardium by EPDCs. To understand the molecular mechanisms by which RA regulates epicardial cytoskeletal rearrangement, we used a whole transcriptome profiling approach, which in combination with pull-down and inhibition assays, demonstrated that the Ras homolog gene family, member A (RhoA) pathway is required for the morphologic changes induced by RA in epicardial cells. Collectively, these data demonstrate that RA regulates the cytoskeletal rearrangement of epicardial cells via a signaling cascade that involves the RhoA pathway.-Wang, S., Yu, J., Jones, J. W., Pierzchalski, K., Kane, M. A., Trainor, P. A., Xavier-Neto, J., Moise, A. R. Retinoic acid signaling promotes the cytoskeletal rearrangement of embryonic epicardial cells.

AB - INTRODUCTION: High-mobility group box 1 (HMGB1) is a ubiquitous nuclear protein that promotes inflammation when released extracellularly after cellular activation, stress, damage or death. HMGB1 operates as one of the most intriguing molecules in inflammatory disorders via recently elucidated signal and molecular transport mechanisms. Treatments based on antagonists specifically targeting extracellular HMGB1 have generated encouraging results in a wide number of experimental models of infectious and sterile inflammation. Clinical studies are still to come. Areas covered: We here summarize recent advances regarding pathways for extracellular HMGB1 release, receptor usage, and functional consequences of post-translational modifications. The review also addresses results of preclinical HMGB1-targeted therapy studies in multiple inflammatory conditions and outlines the current status of emerging clinical HMGB1-specific antagonists. Expert opinion: Blocking excessive amounts of extracellular HMGB1, particularly the disulfide isoform, offers an attractive clinical opportunity to ameliorate systemic inflammatory diseases. Therapeutic interventions to regulate intracellular HMGB1 biology must still await a deeper understanding of intracellular HMGB1 functions. Future work is needed to create more robust assays to evaluate functional bioactivity of HMGB1 antagonists. Forthcoming clinical studies would also greatly benefit from a development of antibody-based assays to quantify HMGB1 redox isoforms, presently assessed by mass spectrometry methods.

AB - OBJECTIVE: Pulmonary fibrosis (PF) is a chronic respiratory system disease. The role of inflammation and angiotensin in the development and progression of PF has previously been demonstrated. Alternation in antifibrotic/profibrotic mediators and NF-kappaB activation have important roles in PF development. NF-kappaB, a nuclear factor, induces the transcription of inflammatory and pro-inflammatory cytokines. The aim of this study was to evaluate the effect of valsartan as an angiotensin receptor blocker on IL-4, INF-gamma, and NF-kappaB expression in the treatment of PF. MATERIALS AND METHODS: Rats were divided into five groups: groups I (bleomycin) and II (control) received a single injection of bleomycin (7.5 IU/kg) or vehicle, respectively. Groups III-V received valsartan (20, 40, and 80 mg/kg, respectively) orally a week before and for 3 weeks after the bleomycin injection. Serum levels of IL-4 and INF- gamma were then measured. Relative NF-kappaB expression was investigated by real-time PCR. RESULTS: Histopathological examination showed the anti-inflammation effect of valsartan. Bleomycin significantly increased IL-4 serum level and decreased that of INF gamma in the serum. Valsartan could restore their levels to normal. Valsartan raised the decreased ratio of INF-gamma/IL-4. Exposure to bleomycin elevated NF kappaB expression; and valsartan decreased the increased gene expression. DISCUSSION: Valsartan as an angiotensin receptor antagonist presumably by blocking angiotensin receptor causes to ameliorated PF, which was at least partly due to antifibrotic/profibrotic cytokine regulation and reduced NF-kappaB expression. CONCLUSIONS: Valsartan showed a significant protective effect against bleomycin-induced PF.

AB - Endometriosis is among the prevalent gynecological diseases and diagnosed in 10% of women of reproductive age. Endometriosis/adenomyosis is becoming increasingly a health-social problem, which is associated with severe clinical manifestations and recurrent disease which has a negative effect on quality of life, women ability to work and her reproductive function. This article presents modern approaches of drug therapy to treat severe forms of adenomyosis. We have reviewed recent major studies in the field of surgical treatment of this disease, analyzed the main stages of disease progress and the results of our surgeries. Here, we are presenting our own results of long-term post-operative hormonal therapy and complex medical treatment.

AB - Mammographic breast density is an established risk factor for breast cancer and significantly reduces the sensitivity of mammography, yet its use within breast cancer screening programs in Australia is limited. We provide a contemporary snapshot of the role of breast density measurement in screening for breast cancer and review the recent evidence for an increasing role of breast density measurement as: a predictor of breast cancer risk, a predictor of 'masking', and a biomarker to monitor effectiveness of intervention strategies for primary prevention or improved breast cancer outcomes. PMID- 29447011 TI - The genotoxic and antigenotoxic potential of the methanolic root extract of Glycyrrhiza glabra L. on human peripheral blood lymphocytes. AB - Glycyrrhiza glabra L. (licorice) is one of the most important medicinal plants, which is widely used throughout the world both in traditional and contemporary medical industries. This study was undertaken to investigate the potential genotoxic activity of G. glabra methanolic root extract, and its possible antigenotoxic properties against mitomycin C (MMC)-induced DNA damage in in vitro chromosome aberrations (CAs) and cytokinesis-block micronucleus (CBMN) assays in human peripheral blood lymphocytes (PBLs). Lymphocytes were treated with 25, 50, and 100 ug/ml G. glabra methanolic root extract alone as well as in combination with MMC (0.1 ug/ml) for 24 and 48 h treatment periods. It was found that there were no statistically significant differences between the negative control and the groups treated with all concentrations of G. glabra root extract of alone (p > 0.05), demonstrating the absence of genotoxic effects at both 24 and 48 h treatment periods. Besides, the co-treatment of G. glabra methanolic root extract and MMC significantly decreased the percentage of structural CAs and MN formation when compared with the culture treated with MMC alone (p < 0.001). In addition, the negative interaction factor (IF) values obtained for all combinations represent an antagonistic effect of G. glabra versus MMC. We can state that this extract acts as an antagonist and markedly decreased MMC-induced cytogenotoxicity. In conclusion, the present results demonstrate that in the tested experimental conditions, G. glabra methanolic root extract is not genotoxic in cultured human PBLs and has also antigenotoxic activity against MMC, which is widely used in chemotherapy against cancer. PMID- 29447013 TI - Identification of Three Types of alpha-Thalassemia Deletion, -alpha21.9, alpha2.4, and - -THAI, and Their Frequencies, in One Family in the Population of Southern Guangxi Zhuang Autonomous Region, People's Republic of China. AB - Different types of deletional alpha-thalassemia (alpha-thal) have been reported by researchers in China. This study describes one family carrying -alpha21.9 (NG_000006.1: g.14373_36299delinsGGGAAGGGTGGGTGGGAATAACAGCTTTT), -alpha2.4 (NG_000006.1: g.36860_39251del) and - -THAI (Thailand) (NG_000006.1: g.10664_44164del) alleles in Guangxi Zhuang Autonomous Region, People's Republic of China (PRC), and reports the frequencies of these types in the population of this region. The proband was a 4-year-old girl, who screened positive for thalassemia, although the thalassemia genotype results were normal when screened using the routine kits. Samples of the proband's parents were also collected to perform further analyses. Two real-time gap-polymerase chain reaction (gap-PCR) systems were designed for separate detection of - -THAI and screening for alpha21.9 and -alpha2.4. The genotype of the proband was -alpha21.9/-alpha2.4, and the two variants were inherited from her parents. In the frequency study, five - -THAI, four -alpha21.9 and 11 -alpha2.4 positive individuals were detected in the 3410 random samples. Thus, allele frequencies of -alpha21.9, - -THAI and alpha2.4 in the population of southern Guangxi were determined as 0.059, 0.073 and 0.161%, respectively. This is the first report of an individual carrying the alpha21.9/-alpha2.4 genotype, and the first report of the detection of alpha21.9, -alpha2.4 and - -THAI in a single family. The total frequency for these alleles was 0.293% in southern Guangxi, suggesting that the thalassemia clinical center in this region should utilize a screening kit that allows detection of these types of deletions for a more comprehensive evaluation of thalassemia risk. PMID- 29447012 TI - Structure-activity relationship investigation of tertiary amine derivatives of cinnamic acid as acetylcholinesterase and butyrylcholinesterase inhibitors: compared with that of phenylpropionic acid, sorbic acid and hexanoic acid. AB - In the present investigation, 48 new tertiary amine derivatives of cinnamic acid, phenylpropionic acid, sorbic acid and hexanoic acid (4d-6g, 10d-12g, 16d-18g and 22d-24g) were designed, synthesized and evaluated for the effect on AChE and BChE in vitro. The results revealed that the alteration of aminoalkyl types and substituted positions markedly influences the effects in inhibiting AChE. Almost of all cinnamic acid derivatives had the most potent inhibitory activity than that of other acid derivatives with the same aminoalkyl side chain. Unsaturated bond and benzene ring in cinnamic acid scaffold seems important for the inhibitory activity against AChE. Among them, compound 6g revealed the most potent AChE inhibitory activity (IC50 value: 3.64 umol/L) and highest selectivity over BChE (ratio: 28.6). Enzyme kinetic study showed that it present a mixed-type inhibition against AChE. The molecular docking study suggested that it can bind with the catalytic site and peripheral site of AChE. PMID- 29447014 TI - Macrophage migration inhibitory factor (MIF) inhibitor, Z-590 suppresses cartilage destruction in adjuvant-induced arthritis via inhibition of macrophage inflammatory activation. AB - BACKGROUND: Macrophage migration inhibitory factor (MIF) is a pleiotropic pro inflammatory mediator that is involved in the progression of rheumatoid arthritis (RA). Previously, we demonstrated a small molecule compound 3-[(biphenyl-4 ylcarbonyl) carbamothioyl] amino benzoic acid (Z-590) could inhibit MIF activity with docking-based virtual screening and experimental evaluation. METHODS: The LPS activated RAW264.7 macrophage cells were used to determine the anti inflammatory effects of Z-590 in vitro. A rat adjuvant-induced arthritis (AIA) model was used to determine the anti-arthritic effects of Z-590 in vivo. RESULTS: MIF inhibitor Z-590 significantly inhibited the production of NO, TNF-alpha and IL-6 in LPS-activated RAW 264.7 macrophage cells and markedly inhibited LPS induced expression of TNF-alpha, IL-6, inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2). Z-590 also significantly reduced paw edema, serum level of TNF-alpha, IL-6 and spleen index in the adjuvant-induced arthritis (AIA) rat model. Furthermore, Z-590 markedly ameliorated joint inflammation and articular cartilage damage in AIA rat model. CONCLUSION: MIF inhibitor Z-590 possesses potent anti-arthritic activity through suppression of macrophage activation, and could be a potential therapeutic treatment for RA.

AB - INTRODUCTION: The discovery and domestication of biomolecules that respond to light has taken a light of its own, providing new molecular tools with incredible spatio-temporal resolution to manipulate cellular behavior. Areas covered: The authors herein analyze the current optogenetic tools in light of their current, and potential, uses in cancer drug discovery, biosafety and cancer biology. Expert opinion: The pipeline from drug discovery to the clinic is plagued with drawbacks, where most drugs fail in either efficacy or safety. These issues require the redesign of the pipeline and the development of more controllable/personalized therapies. Light is, aside from inexpensive, almost harmless if used appropriately, can be directed to single cells or organs with controllable penetration, and comes in a variety of wavelengths. Light-responsive systems can activate, inhibit or compensate cell signaling pathways or specific cellular events, allowing the specific control of the genome and epigenome, and modulate cell fate and transformation. These synthetic molecular tools have the potential to revolutionize drug discovery and cancer research.

PMID- 29447016 TI - TGF-b1 or hypoxia enhance glucose metabolism and lactate production via HIF1A signaling in tendon cells. AB - : Purpose/Aim of the study: Healthy tendons are maintained in homeostasis through controlled usage of glucose for energy and redox equilibrium. Tendon cell stress imposed by overuse injury or vascular insufficiency is accompanied by activation of wound healing pathways which facilitate an adaptive response and the restoration of homeostasis. To understand this response at the gene expression level we have studied the in vivo effects of injected TGF-beta1 in a murine model of tendinopathy, as well as treatment of murine tendon explants with either TGF beta1 or hypoxia in vitro. METHODS AND RESULTS: We provide evidence (from expression patterns and immunohistochemistry) that both in vivo and in vitro, the stress response in tendon cells may be metabolically controlled in part by glycolytic reprogramming. A major feature of the response to TGF-beta1 or hypoxia is activation of the Warburg pathway which generates lactate from glucose under normoxia and thereby inhibits mitochondrial energy production. CONCLUSIONS: We discuss the likely outcome of this major metabolic shift in terms of the potential benefits and damage to tendon and suggest how incorporation of this metabolic response into our understanding of initiation and progression of tendinopathies may offer new opportunities for diagnosis and the monitoring of therapies. PMID- 29447018 TI - Summary of numerical analyses for therapeutic uses of laser-activated gold nanoparticles. AB - The optimal light dose, heat generation, consequent heat spread and an accurate thermal damage model, are key components of effective laser therapies. Recent advances in nanotechnology offer numerous possibilities on how to increase the efficacy of hyperthermia for tumour treatments. Gold nanoparticles are a promising candidate towards the achievement of this goal owing to their properties for efficiently converting light to heat. In this review, we summarise the numerical tools that are available for theoretical studies of gold nanoparticle-mediated photo-thermal therapy. The processes that occur in the treatments based on light propagation inside biological tissues and the subsequent temperature distributions are considered first, followed by evaluation of the thermal damage. The fundamental ideas underlying the presented methods are described in addition to their applications in photo-thermal therapy and its effects. The descriptions of extensively used tools for the characterisation of nanoparticles across multiple research fields are also presented for estimating the electromagnetic properties of gold nanoparticles (e.g. discrete dipole approximations, finite-difference time-domain simulations), the Monte Carlo model of light propagation in biological tissues, and the Pennes' bio-heat equation. In addition, the Arrhenius damage evaluation and the cumulative effective minutes normalisation methods are described. Finally, recent in vivo and in vitro results from the rapidly growing field of nanomedicine are presented. PMID- 29447019 TI - Lysophosphatidic acid enhanced the osteogenic and angiogenic capability of osteoblasts via LPA1/3 receptor. AB - Lysophosphatidic acid is a serum-derived growth factor that is involved in wound healing. Although in its infancy, a growing body of evidence has demonstrated that lysophosphatidic acid exerts a potentially significant role in regulating bone cell biology. However, previous studies mainly focused on the osteoinductive potential of lysophosphatidic acid, its effects on bone tissue vascularization, another essential element during bone regeneration, remains ill-defined so far. Here in this study, we examined the effects of lysophosphatidic acid on osteogenic differentiation as well as the angiogenesis-inducing capacity of pre osteoblasts, a cell population that coordinates osteogenic and angiogenic processes in bone regenerating niche. Our results showed that treatment of MC3T3 E1 pre-osteoblastic cells with lysophosphatidic acid enhanced alkaline phosphatase activity and matrix mineralization, demonstrating in vitro osteoblastic differentiation. Of particular importance was the finding that vascular endothelial growth factor secretion also increased after lysophosphatidic acid treatment. Lysophosphatidic acid conditioned media of MC3T3 E1 cells was capable of promoting angiogenic behavior of endothelial cells, as evidenced by stimulating proliferation, migration, and tube formation. Besides, inhibition of LPA1/3 receptor abolished lysophosphatidic acid-induced elevation of the osteogenic and angiogenic capability of pre-osteoblasts. Our research demonstrated the important role of lysophosphatidic acid in coupling osteogenesis and angiogenesis during bone remodeling through orchestrating pre-osteoblast behavior, and implications therein for novel and effective treatment strategies for bone regeneration success. PMID- 29447020 TI - Effect of pre-treatment with gonadotropin-releasing hormone analogue GnRH-alpha on high-intensity focussed ultrasound ablation for diffuse adenomyosis: a preliminary study. AB - OBJECTIVES: To evaluate the efficacy and safety of GnRH-alpha pre-treatment with HIFU ablation for diffuse adenomyosis. METHODS: From January 2014 to December 2016, 61 patients were divided into two groups. Twenty-three patients with larger uteri received pre-treatment with GnRH-alpha and were then subjected to HIFU, and 38 patients underwent HIFU alone. The technical parameters included treatment time, sonication time, average sonication power, treatment intensity, total energy, non-perfusion volume (NPV) and NPV ratio. Intra-, post-procedural complaints, the relief rate of dysmenorrhoea and clinical effectiveness were followed up. RESULTS: Although the lesion volume in the HIFU + GnRH group was larger than in the HIFU-only group, higher NPV, NPVR%, treatment intensity and total energy with shorter treatment and sonication times in the HIFU + GnRH group were obtained than that in the HIFU-only group. Significant differences were evident for NPV, NPVR%, average power, and total intensity energy (p < 0.05), but not for other parameters between the two groups (p > 0.05). Although no differences in the intra-, post-procedural VAS scores, in the adverse effects and in the relief rate or clinical effectiveness were apparent between the two groups (p > 0.05), the relief rate was better in the HIFU + GnRH group than that in the HIFU group from 6 to 12 months after treatment. Self-comparison of differences occurred in the two groups before and after treatment (p < 0.05) and were between the two groups after only 6 months (p < 0.05). CONCLUSION: The combination of HIFU with GnRH-alpha is more effective than HIFU alone for ablation of diffuse adenomyosis. Moreover, the GnRH-alpha pre-treatment with HIFU is safe.

PMID- 29447023 TI - Designing a Low-Cost, Single-Supply ECG System for Suppression of Movement Artifact from Contaminated Magnetocardiogram. AB - Measurement of the late potentials and His-bundle activity is crucial for many clinical studies using the noncontact and noninvasive magnetocardiography (MCG) technique; these weak signals are extracted by averaging many cardiac cycles aligned using the R-peak of the cardiac cycle identified using an electrocardiography (ECG) lead. ECG is measured simultaneously with MCG using a conventional dual-supply ECG amplifier, which requires either two separate batteries or a single battery with a switching voltage inverter circuit for its proper operation. The ECG circuitry based on two separate batteries requires a relatively large voltage supply (-18 to +18 V). The single-supply (low voltage: 0 9 V) ECG circuitry may be implemented using a switching voltage inverter; however, this mode of operation introduces switching noise in the system. The objective of the present work is to overcome these problems by carefully designing a low-voltage, single-supply ECG system, which can be used simultaneously with the MCG setup without introducing a significant level of additional noise in the MCG measurement system. PMID- 29447024 TI - Microbiology and clinical outcomes of puerperal sepsis: a prospective cohort study. AB - The objectives of this study were to determine the identity and antibacterial susceptibility profiles of bacteria colonising the female genital tract and blood stream and their association with clinical outcomes in women with puerperal sepsis. A prospective descriptive cohort study was conducted at two tertiary hospitals in Zimbabwe. Endocervical swabs and blood were collected for culture and susceptibility testing from 151 consecutive women who met the World Health Organisation criteria for puerperal sepsis. Medical records were reviewed for assessment of clinical outcomes. The commonest bacterial isolates were Escherichia coli (30.6%) and Klebsiella pneumoniae (15.3%). Multidrug-resistant organisms (MDRO) accounted for 10.9% of all isolates. MDRO were associated with prolonged hospital stay, 23.0 days compared to 10.5 days in women without MDRO (p = .009). Puerperal sepsis case fatality rate was 7.3%. Clinical culture surveillance to monitor epidemiologic trends, identify MDRO, robust infection control strategies and emphasis on rational drug use are recommended. Impact statement What is already known? Puerperal sepsis is often a polymicrobial infection. Escherichia coli has been reported as a common cause of severe maternal sepsis originating from the genital tract. Other bacteria include Group A Streptococcus, S. aureus, Streptococcus spp. Klebsiellae spp, Pseudomonas spp. and anaerobes. What does this study add? This study confirms Escherichia coli as the commonest cause of sepsis in Harare. There is high level resistance to first line antibiotic regimens on most Gram-negative isolates from the endocervix among women with puerperal sepsis. Emerging resistance to carbapenems is demonstrated. MDRO significantly increased length of hospital stay, and there was a clinically important trend towards higher rates of pelvic abscess, septic shock, death, need for laparotomy and ICU admission specific to puerperal sepsis. What are the implications for clinical practice and further research? Clinical culture surveillance to monitor epidemiologic trends in conjunction with robust infection control strategies and rational drug use may assist in prevention of community acquired and nosocomial multidrug-resistant infections. PMID- 29447021 TI - Release of pro-inflammatory cytokines from muscle and bone causes tenocyte death in a novel rotator cuff in vitro explant culture model. AB - PURPOSE: Tendinopathy is a significant clinical problem thought to be associated with altered mechanical loading. Explant culture models allow researchers to alter mechanical loading in a controlled in vitro environment while maintaining tenocytes in their native matrix. However, current models do not accurately represent commonly injured tendons, ignoring contributions of associated musculature and bone, as well as regional collagen structure. This study details the characterization of amouse rotator cuff explant culture model, including bone, tendon, and muscle (BTM). MATERIALS AND METHODS: Following harvest, BTM explants were maintained in stress-deprived culture for one week and tendon was then assessed for changes in cell viability, metabolism, matrix structure and content. RESULTS: Matrix turnover occurred throughout culture as manifested in both gene expression and biosynthesis, but this did not translate to net changes in total collagen or sulfated glycosaminoglycan content. Furthermore, tendon structure was not significantly altered throughout culture. However, we found significant cell death in BTM tendons after 3 days in culture, which we hypothesize is cytokine-induced. Using a targeted multiplex assay, we found high levels of pro-inflammatory cytokines released to the culture medium from muscle and bone, levels that did cause cell deathin tendon-alone controls. CONCLUSIONS: Overall, this model presents an innovative approach to understandingrotator cuff injury and tenocyte mechanobiology in a clinically-relevant tendon structure. Our model can be a powerful tool to investigate how mechanical and biological stimuli can alter normal tendon health and lead to tendon degeneration, and may provide a testbed for therapeutics for tendon repair. PMID- 29447025 TI - Anal sphincter dysfunction in patients treated with primary radiotherapy for anal cancer: a study with the functional lumen imaging probe. AB - BACKGROUND: Sphincter-sparing radiotherapy or chemoradiation are standard treatments for patients with anal cancer. The ultimate treatment goal is full recovery from anal cancer with preserved anorectal function. Unfortunately, long term survivors often suffer from severe anorectal symptoms. The aim of the present study was to characterize changes in anorectal physiology after radiotherapy for anal cancer. METHOD: We included 13 patients (10 women, age 63.4 +/- 1.9) treated with radiotherapy or chemoradiation for anal cancer and 14 healthy volunteers (9 women, age 61.4 +/- 1.5). Symptoms were assessed with scores for fecal incontinence and low anterior resection syndrome. Anorectal physiology was examined with anorectal manometry and the Functional Lumen Imaging Probe. RESULTS: Patients had a median Wexner fecal incontinence score of 5 (0-13) and a median LARS score of 29 (0-39). Compared to healthy volunteers, patients had lower mean (+/-SE) anal -resting (38 +/- 5 vs. 71 +/- 6, p < .001) and squeeze pressures (76 +/- 11 vs. 165 +/- 15, p < .001). Patients also had lower anal yield pressure (15.5 +/- 1.3 mmHg vs. 28.0 +/- 2.0 mmHg, p < .001), higher distensibility, and lower resistance to flow (reduced resistance ratio of the anal canal during distension, q = 5.09, p < .001). No differences were found in median (range) rectal volumes at first sensation (70.5 (15-131) vs. 57 (18-132) ml, p > .4), urge (103 (54-176) vs. 90 (32-212), p > .6) or maximum tolerable volume (173 (86-413) vs. 119.5 (54-269) ml, p > .10). CONCLUSION: Patients treated with radiotherapy or chemoradiation for anal cancer have low anal resting and squeeze pressures as well as reduced resistance to distension and flow.

PMID- 29447027 TI - Current knowledge of transient hypothyroxinemia of prematurity: to treat or not to treat? AB - BACKGROUND: Thyroid hormones (THs) play a critical role in normal maturation of the developing brain in the fetus and infant. Continuing advances in neonatal medicine have contributed to an increased survival of extremely premature infants with neonatal morbidities. In these infants, thyroid system immaturities, as well as morbidity-related thyroid dysfunction, contribute to transient hypothyroxinemia of prematurity (THOP), which is characterized by very low total and free thyroxine and normal or low thyroid-stimulating hormone (TSH) levels. REVIEW: Undoubtedly, low levels of THs with elevated TSH are associated with poor neurodevelopmental outcome. However, continuing debate exists regarding whether THOP is harmful to the developing brain. Moreover, no clear effects of TH treatment on neurodevelopmental outcome in preterm infants with THOP have been demonstrated. THs could have unpredictable effects if given unnecessarily. CONCLUSION: The current recommendation is to treat THOP with TH only if THOP is accompanied with TSH elevation. PMID- 29447028 TI - Elastase as a potential biomarker for radiation-induced gut wall injury of the distal bowel in an experimental mouse model. AB - BACKGROUND AND PURPOSE: Traditionally, elastase has been used to study exocrine activity of the pancreas in patients with chronic pancreatitis and cystic fibrosis, and calprotectin as a marker for gut-wall inflammation in patients with inflammatory bowel disease. The aim of the study was to find out whether elastase and calprotectin could be used as inflammatory markers for radiation-induced gut wall injury of the distal bowel. MATERIAL AND METHODS: Adult male mice were exposed to two, three, or four fractions of 6 Gy or 8 Gy irradiation to the sigmoid and rectum of the large bowel, using a linear accelerator. Fecal samples were collected from mice at 1, 3, and 6 weeks post-irradiation. The fecal levels of elastase and calprotectin were analyzed using ELISA. RESULTS: Three and 6 weeks after irradiation, we found a dose-effect relationship between dose of ionizing radiation and the fecal level of elastase; that is significantly higher levels of elastase were observed in mice that had received a high irradiation dose. We also found that irradiated mice hosted in the same cage had a comparable level (either high or low) of elastase. No significant differences were observed from the calprotectin data. CONCLUSIONS: We found a clear association between the dose of ionizing radiation to the distal colon and the level of elastase in the fecal samples.

AB - Nanosilver (Ag NPs) is currently one of the most commercialized antimicrobial nanoparticles with as yet, still unresolved cytotoxicity origins. To date, research efforts have mostly described the antimicrobial contribution from the leaching of soluble silver, while the undissolved solid Ag particulates are often considered as being microbiologically inert, serving only as source of the cytotoxic Ag ions. Here, we show the rapid stimulation of lethal cellular oxidative stress in bacteria by the presence of the undissolved Ag particulates. The cytotoxicity characteristics are distinct from those arising from the leached soluble Ag, the latter being locked in organic complexes. The work also highlights the unique oxidative stress-independent bacterial toxicity of silver salt. Taken together, the findings advocate that future enquiries on the antimicrobial potency and also importantly, the environmental and clinical impact of Ag NPs use, should pay attention to the potential bacterial toxicological responses to the undissolved Ag particulates, rather than just to the leaching of soluble silver. The findings also put into question the common use of silver salt as model material for evaluating bacterial toxicity of Ag NPs. PMID- 29447031 TI - Patient-Physician E-Mail.

PMID- 29447043 TI - Re-engineering the interpretation of electronic fetal monitoring to identify reversible risk for cerebral palsy: a case control series. AB - BACKGROUND: Even key opinion leaders now concede that electronic fetal monitoring (EFM) cannot reliably identify fetal acidemia which many vouch as the only labor mediated pathophysiologic precursor for cerebral palsy (CP). We have developed the "Fetal Reserve Index" - an algorithm combining five dynamic components of EFM (1. Rate, 2. Variability, 3. Accelerations, 4. Decelerations, and 5. Excessive uterine activity) considered individually that are combined with the presence of: 6. maternal, 7. obstetrical, and 8. fetal risk factors. OBJECTIVE: Here, we compare this 8-point fetal reserve index (FRI) against the performance of ACOG monograph criteria and ACOG Category systems for predicting risk for both CP and the need for emergency operative delivery (EOD). We then studied how varied management for screen positives (Red zone-defined below) impacts the outcome of such cases. STUDY DESIGN: Four hundred twenty term patients were studied: all entered labor with normal EFMs and no apparent cause of harm except events of labor and delivery. Sixty subsequently developed CP, and 360 were apparently normal controls. An FRI, normal on all eight parameters scored 100%, 4 of the 8 was 50%, etc. We divided cases into Green zone >50%, Yellow 50-26%, and Red <=25%. An FRI in the Red zone was considered a positive screen. We then compared performance metrics for the three evaluation schemes and differences between controls that reached Red against those controls whose worst scores were Green/Yellow. RESULTS: For detection of injury during labor, the FRI performed much better than the ACOG Category criteria (sensitivity 28%), and Category III (45%) (p < .001). All CP cases reached Red zone and were Red for a minimum of 2 hours (mean = 5.35 hours). Twenty-four% of controls reached Red, but were only Red for average of 1 hr. The incidence of low Apgar's, pH, FRI, and Lowest FRI increased progressively from Green/Yellow controls to red controls to CP cases. Irrespective, CP cases met ACOG Monograph criteria for labor injury less than 50% of the time. Only half of CP babies had umbilical artery pH values <7.00, and less than 50% showed Category III patterns. The earlier in labor the Red zone was reached, the more likely for a baby to develop CP or the mother to require an EOD regardless of fetal outcome. Successful intrauterine resuscitations (IR) diminished time spent in the Red zone and the need for EODs. CONCLUSIONS: FRI shows better discrimination for adverse fetal outcome and EOD than traditional EFM interpretation. The Category system is a very poor, subjective screening method as the vast majority of CP babies never reach the "action point" result of Category III. While reaching the Red zone does not ordain a bad outcome, how it is managed, does. Compared to CP cases, Red controls were delivered faster, had higher FRIs, and often had prompt management including IR maneuvers, which improved the FRI and lowered the risk of EODs even for cases with normal outcomes. With further study and validation, the quantitative FRI approach may replace the current, very subjective interpretation with a quantitative "lab test" approach. PMID- 29447044 TI - Improving the health of mental health staff through exercise interventions: a systematic review. AB - BACKGROUND: Exercise interventions are efficacious in reducing cardiometabolic risk and improving symptoms in people with severe mental illness, yet evidence guiding the implementation and scalability of such efforts is lacking. Given increasing efforts to address the disparity in physical health outcomes facing people with a mental illness, novel approaches to increasing adoption of effective interventions are required. Exercise interventions targeting mental health staff may improve staff health while also creating more positive attitudes towards the role of lifestyle interventions for people experiencing mental illness. AIMS: We aimed to determine the feasibility, acceptability and effectiveness of exercise interventions delivered to staff working in mental health services. METHOD: A systematic review was conducted from database inception, until November 2017. Studies recruiting staff participants to receive an exercise intervention were eligible for inclusion. RESULTS: Five studies met the inclusion criteria. Physical health interventions for mental health staff were feasible and acceptable with low dropout rates. Reductions in anthropometric measures and work-related stress were reported. CONCLUSIONS: Limited evidence suggests that exercise interventions targeting mental health staff are feasible and acceptable. Further research is required to determine the efficacy of such interventions and the impact such strategies may have on staff culture and patient outcomes.

AB - A four-channel electrochemical impedance spectroscopy (EIS) analyzer module has been demonstrated on flexible chemi-impedance sensors fabricated with gold electrodes for wearable applications. The module can perform time division multiplexed (TDM) impedance measurements on four sensors at 1 kHz. In this work, we characterize the system for the detection of cortisol in an ultralow volume (1 3 uL) of perspired human sweat, sensor performance, and effects during continuous cortisol dosing and with pH and temperature variations expected on the surface of the skin that would be representative of use conditions as seen by a wearable device. Detection of cortisol was shown for concentrations of 1 pg/mL to 200 ng/mL in both synthetic and perspired human sweat, and output response reported as a change in impedance with varying cortisol concentrations. Continuous dose testing was performed to demonstrate the stability of the sensors over prolonged periods of operation for cortisol concentrations within the physiologically relevant range of 10-200 ng/mL reported in human sweat. Temperature and pH effects testing was performed for pH range 4-8 and in a temperature chamber for the clinical range reported on the surface of human skin: 25-40 degrees C. The cortisol sensor demonstrated stability of operation with 7.58% variability under these conditions.

AB - AIM: Information and communication technologies (ICTs) offer immense benefits for university students including enhancing engagement and connections with others and promoting self-directed and interactive learning. Perceived anonymity and the absence of social cues, however, may contribute to risk of interpersonal aggression. While extensive research examines bullying in child and adolescent educational settings, this study addresses a gap regarding post-secondary environments. METHODS: An internet-based survey was provided to 5004 university students to examine the nature, extent and consequences of cyber-aggression. The survey received a response from 1350 students, a response rate of 28.5%. To enable further exploration, nine focus groups and eight individual interviews were conducted. RESULTS: This exploratory study found one quarter of respondents had a private video or photo shared without their permission and 28% were sent angry, vulgar, threatening or intimating messages. Perpetrators were most likely to be a friend (50%), another student (20%) or an intimate partner (18%). Focus group data revealed risks of ICTs and the need for resources and support to address students' wellbeing in the context of cyber-aggression. CONCLUSION: Cyber aggression is experienced by a significant minority of university students, impacting their sense of wellbeing and mental health. PMID- 29447047 TI - Prospective comparative study of 18F-sodium fluoride PET/CT and planar bone scintigraphy for treatment response assessment of bone metastases in patients with prostate cancer. AB - AIM: To compare 18F-sodium fluoride positron emission tomography/computed tomography (NaF PET/CT) and 99mTc-labelled diphosphonate bone scan (BS) for the monitoring of bone metastases in patients with prostate cancer undergoing anti cancer treatment. MATERIAL AND METHODS: Data from 64 patients with prostate cancer were included. The patients received androgen-deprivation therapy (ADT), next-generation hormonal therapy (NGH) or chemotherapy. The patients had a baseline scan and 1-3 subsequent scans during six months of treatment. Images were evaluated by experienced nuclear medicine physicians and classified for progressive disease (PD) or non-PD according to the Prostate Cancer Working Group 2 (PCWG-2) criteria. The patients were also classified as having PD/non-PD according to the clinical and prostate-specific antigen (PSA) responses. RESULTS: There was no difference between NaF PET/CT and BS in the detection of PD and non PD during treatment (McNemar's test, p = .18). The agreement between BS and NaF PET/CT for PD/non-PD was moderate (Cohen's kappa 0.53, 95% confidence interval 0.26-0.79). Crude agreement between BS and NaF PET/CT for the assessment of PD/non-PD was 86% (89% for ADT, n = 28; 88% for NGH, n = 16, and 80% for chemotherapy, n = 20). In most discordant cases, BS found PD when NaF PET/CT did not, or BS detected PD on an earlier scan than NaF PET/CT. Biochemical progression (27%) occurred more frequently than progression on functional imaging (BS, 22% and NaF PET/CT, 14%). Clinical progression was rare (11%), and almost exclusively seen in patients receiving chemotherapy. CONCLUSION: There was no difference between NaF PET/CT and BS in the detection of PD and non-PD; however, BS seemingly detects PD by the PCWG-2 criteria earlier than NaF-PET, which might be explained by the fact that NaF-PET is more sensitive at the baseline scan. PMID- 29447046 TI - Oral curcumin supplementation improves fine motor function in the middle-aged rhesus monkey. AB - Aged individuals experience decreased fine motor function of the hand and digits, which could result, in part, from the chronic, systemic state of inflammation that occurs with aging. Recent research for treating age-related inflammation has focused on the effects of nutraceuticals that have anti-inflammatory properties. One particular dietary polyphenol, curcumin, the principal curcuminoid of the spice turmeric, has been shown to have significant anti-inflammatory effects and there is mounting evidence that curcumin may serve to reduce systemic inflammation. Therefore, it could be useful for alleviating age-related impairments in fine motor function. To test this hypothesis we assessed the efficacy of a dietary intervention with a commercially available optimized curcumin to ameliorate or delay the effects of aging on fine motor function of the hand of rhesus monkeys. We administered oral daily doses of curcumin or a control vehicle to 11 monkeys over a 14- to 18-month period in which they completed two rounds of fine motor function testing. The monkeys receiving curcumin were significantly faster at retrieving a food reward by round 2 of testing than monkeys receiving a control vehicle. Further, the monkeys receiving curcumin demonstrated a greater degree of improvement in performance on our fine motor task by round 2 of testing than monkeys receiving a control vehicle. These findings reveal that fine motor function of the hand and digits is improved in middle-aged monkeys receiving chronic daily administration of curcumin. PMID- 29447049 TI - Impact of acute and subchronic inhalation exposure to PbO nanoparticles on mice. AB - Lead nanoparticles (NPs) are released into air from metal processing, road transport or combustion processes. Inhalation exposure is therefore very likely to occur. However, even though the effects of bulk lead are well known, there is limited knowledge regarding impact of Pb NPs inhalation. This study focused on acute and subchronic exposures to lead oxide nanoparticles (PbO NPs). Mice were exposed to PbO NPs in whole body inhalation chambers for 4-72 h in acute experiment (4.05 * 106 PbO NPs/cm3), and for 1-11 weeks in subchronic experiment (3.83 * 105 particles/cm3 in lower and 1.93 * 106 particles/cm3 in higher exposure group). Presence of NPs was confirmed in all studied organs, including brain, which is very important considering lead neurotoxicity. Lead concentration gradually increased in all tissues depending on the exposure concentration and duration. The most burdened organs were lung and kidney, however liver and brain also showed significant increase of lead concentration during exposure. Histological analysis documented numerous morphological alterations and tissue damage, mainly in lung, but also in liver. Mild pathological changes were observed also in kidney and brain. Levels of glutathione (reduced and oxidized) were modulated mainly in lung in both, acute and subchronic exposures. Increase of lipid peroxidation was observed in kidney after acute exposure. This study characterized impacts of short to longer-term inhalation exposure, proved transport of PbO NPs to secondary organs, documented time and concentration dependent gradual increase of Pb concentration and histopathological damage in tissues. PMID- 29447050 TI - Added value of cerebro-placental ratio and uterine artery Doppler at routine third trimester screening as a predictor of SGA and FGR in non-selected pregnancies. AB - OBJECTIVES: The objective of this study is to determine the added value of cerebroplacental ratio (CPR) and uterine Doppler velocimetry at third trimester scan in an unselected obstetric population to predict smallness and growth restriction. METHODS: We constructed a prospective cohort study of women with singleton pregnancies attended for routine third trimester screening (32+0-34+6 weeks). Fetal biometry and fetal-maternal Doppler ultrasound examinations were performed by certified sonographers. The CPR was calculated as a ratio of the middle cerebral artery to the umbilical artery pulsatility indices. Both attending professionals and patients were blinded to the results, except in cases of estimated fetal weight < p10. The association between third trimester Doppler parameters and small for gestational age (SGA) (birth weight <10th centile) and fetal growth restriction (FGR) (birth weight below the third centile) was assessed by logistic regression, where the basal comparison was a model comprising maternal characteristics and estimated fetal weight (EFW). RESULTS: A total of 1030 pregnancies were included. The mean gestational age at scan was 33 weeks (SD 0.6). The addition of CPR and uterine Doppler to maternal characteristics plus EFW improved the explained uncertainty of the predicting models for SGA (15 versus 10%, p < .001) and FGR (12 versus 8%, p = .03). However, the addition of CPR and uterine Doppler to maternal characteristics plus EFW only marginally improved the detection rates for SGA (38 versus 34% for a 10% of false positives) and did not change the predictive performance for FGR. CONCLUSIONS: The added value of CPR and uterine Doppler at 33 weeks of gestation for detecting defective growth is poor. PMID- 29447051 TI - Targeting crosstalk between Nuclear factor (erythroid-derived 2)-like 2 and Nuclear factor kappa beta pathway by Nrf2 activator dimethyl fumarate in epileptogenesis. AB - : Purpose/Aim: Epilepsy is a complex, chronic neurological disorder characterized by increased and abnormal synchronization of neuronal electrical activity, which is manifested as seizures. It is associated with many comorbid conditions such as depression, anxiety, sleep disorder, psychiatric disorder etc., which consequently causes higher mortality rate. The understanding of its cellular and molecular mechanism is partial, because of which it remains an ongoing health problem, despite the increasing availability of newer antiepileptic drugs. Although recurrent seizures are the clinical indication of epilepsy, the disease process (epileptogenesis) begins before the onset of the first seizure. This dormant phase before the onset of first seizure provides an opportune time window for modifying the epileptogenic process by intervening in its progression with an appropriate treatment. MATERIAL AND METHODS: Studies have shown that in epilepsy, there is a chronic state of oxidative stress and inflammation, which plays a key role in epileptic pathogenesis. Various antioxidant mechanisms maintain the redox balance in the body by either scavenging or regulating the generation of free radicals. Nuclear factor (erythroid-derived 2)-like 2 (Nrf2) pathway is a well established antioxidant pathway in various diseases such as diabetes, renal disease, various neurodegenerative disorders such as Parkinson's disease, Alzheimer's disease, Huntington's disease, amyotrophic lateral sclerosis, traumatic brain injury, etc. Results: It has been observed that single-target therapies are inefficient in providing anticonvulsant and disease-modifying effects in epilepsy. CONCLUSIONS: So, preventing the progression of epilepsy by targeting Nrf2-activated antioxidant pathway along with the other established antiepileptic pathways can prove beneficial in epilepsy treatment.

PMID- 29447055 TI - Advanced Microengineered Lung Models for Translational Drug Discovery. AB - Lung diseases impose a significant socioeconomic burden and are a leading cause of morbidity and mortality worldwide. Moreover, respiratory medicine, unlike several other therapeutic areas, faces a disappointingly low number of new approved therapies. This is partly due to lack of reliable in vitro or in vivo models that can reproduce organ-level complexity and pathophysiological responses of human lung. Here, we examine new opportunities in application of recently emerged organ-on-chip technology to model human lung alveolus and small airway in preclinical drug development and biomarker discovery. We also discuss challenges that need to be addressed in coming years to further enhance the physiological and clinical relevance of these microsystems, enable their increased accessibility, and support their leap into personalized medicine. PMID- 29447056 TI - Investigating the psychometric properties of the revised child anxiety and depression scale (RCADS) in a non-clinical sample of Irish adolescents. AB - BACKGROUND: The psychometric properties of the Revised Child Anxiety and Depression Scale (RCADS) have been established cross-culturally, yet psychometric evidence is lacking for an English-speaking European population. AIM: This research sought to further cross-validate the measure in a non-clinical Irish adolescent sample, and to test for gender and age-based differential item functioning in depression and anxiety. METHOD: Participants were Irish second level school students (N = 345; 164 male; 12-18 years, M =14.97, SD = 1.44). Confirmatory factor analysis for categorical data (confirmatory item factor analysis) and multiple-indicator multiple-cause (MIMIC) modelling to identify items displaying possible metric invariance were conducted. RESULTS: A six-factor model fit the data well in both gender samples and both school cycles, as a proxy for age samples. Gender-based metric invariance for 5 of 47 items and age-based metric invariance for three items were identified. However, the magnitudes were small. Internal consistency and validity were also established. CONCLUSIONS: While, a number of items demonstrated minor metric invariance, there was no evidence that they influenced overall scores meaningfully. The RCADS can reasonably be used without adjustment in male and female, younger and older, adolescent samples. Findings have implications for the use of the RCADS in an English-speaking European population. PMID- 29447057 TI - Effect of resin infiltration and microabrasion on the microhardness, surface roughness and morphology of incipient carious lesions. AB - OBJECTIVE: The effects of resin infiltration and microabrasion on incipient carious lesions by surface microhardness, roughness and morphological assessments, and resistance to further acid attack of treated lesions were evaluated. MATERIAL AND METHODS: Eighty artificially-induced incipient lesions were randomly divided into five groups (n = 16): resin infiltration with an adhesive resin (Excite F, Ivoclar Vivadent, Schaan, Liechtenstein), resin infiltration with a resin infiltrant (Icon, DMG, Hamburg, Germany), microabrasion without polishing (Opalustre, Ultradent, South Jordan, UT, USA), microabrasion with polishing (Opalustre, Ultradent, Diamond Excel, FGM, Joinville, SC, Brazil), and distilled water (control group). All specimens were exposed to demineralization for another 10 d. Microhardness, roughness and morphological assessments were done at baseline, following initial demineralization, treatment and further demineralization. Data were analysed by the Kruskal-Wallis, Friedman's and Bonferroni tests (p < .05). RESULTS: Enamel lesions treated with resin infiltrant and microabrasion demonstrated similar hardness values, with a nonsignificant difference compared with sound enamel. Resin infiltration demonstrated lower roughness values than those of microabrasion, and the values did not reach the values of sound enamel. Further demineralization for 10 d did not affect the hardness but increased the roughness of infiltrated and microabraded enamel surfaces. Polishing did not influence the roughness of microabraded enamel surfaces. After resin infiltration, porosities on enamel were sealed completely. The surface structure was similar to that of the enamel conditioning pattern for microabraded enamel lesions. CONCLUSIONS: Within the limitations of this study, the icon infiltration and microabrasion technique appeared to be effective for improving microhardness. Icon appeared to provide reduced roughness, although not equal to sound enamel. Further research is needed to elucidate their clinical relevance. PMID- 29447058 TI - Training and post-disaster interventions for the psychological impacts on disaster-exposed employees: a systematic review. AB - BACKGROUND: When organisations are exposed to traumatic situations, such as disasters, often staff are not prepared for the potential psychological impact which can negatively affect their wellbeing. AIMS: To conduct a systematic review of the literature on psychological interventions aimed at improving staff wellbeing during or after disasters. METHOD: Four electronic literature databases were searched. Reference lists of relevant articles were hand-searched. RESULTS: Fifteen articles were included. Five studies suggested that pre-disaster skills training and disaster education can improve employee confidence. Ten studies on post-disaster interventions revealed mixed findings on the effectiveness of psychological debriefing and limited evidence for cognitive behavioural therapy, psychoeducation and meditation. CONCLUSIONS: Pre-disaster training and education can improve employees' confidence in their ability to cope with disasters. The routine use of post-disaster psychological debriefings is not supported; further research is needed to determine if debriefing interventions could be useful in some circumstances. Further research is needed to provide more evidence on the potential positive effects of cognitive behavioural therapy, psychoeducation and meditation. More experimental studies on psychological disaster interventions are needed. PMID- 29447059 TI - Therapeutic potential of Mucuna pruriens (Linn.) on ageing induced damage in dorsal nerve of the penis and its implication on erectile function: an experimental study using albino rats. AB - OBJECTIVE: To study the effect of ethanolic seed extract of Mucuna pruriens on damaged dorsal nerve of the penis (DNP) in aged rat in relation to penile erection. METHODS: The rats were divided into four groups Young (3 months), Aged (24 - 28 months), Aged + M. pruriens, and Young + M. pruriens (200 mg/kg b.w/60 days) and were subjected to the hypophysial - gonadal axis, nerve conduction velocity (NCV), and penile reflex. DNP sections were stained with nitric oxide synthase (nNOS), nicotinamide adenine dinucleotide phosphate (NaDPH) diaphorase, androgen receptor (AR), and osmium tetroxide. Terminal deoxynucleotidyl transferase (TdT) dUTP Nick-End Labeling (TUNEL) staining, electron microscopy(EM) and histometric analyses were done. RESULTS: Significant disturbance in hypophysial - gonadal axis was noted in aged rat. With reduced number of myelinated fibers, diameter, vacuolization, indentation of the myelin sheath, and degeneration. nNOS and its cofactor (NaDPH diaphorase) were reduced in aged rat DNP. NCV was slow in aged rats and concomitant poor penile reflex was also noted. AR showed reduced expression in aged rat DNP when compared to young and control groups. TUNEL positive cells were increased in aged rat DNP. These pathological changes were remarkably reduced or recovered in M. pruriens treated aged rats. CONCLUSIONS: The results indicate a multi-factorial therapeutic activity in penile innervations towards sustaining the penile erection in the presence of the extract in aged rats and justifying the claim of traditional usage. PMID- 29447060 TI - Treatment of selective mutism based on cognitive behavioural therapy, psychopharmacology and combination therapy - a systematic review. AB - BACKGROUND: Selective mutism (SM) is a debilitating childhood anxiety disorder characterized by a persistent lack of speech in certain social settings and is considered hard to treat. Cognitive behavioral therapy (CBT) and pharmacological treatments are the best described treatments in the literature. AIM: To test whether there is evidence on treatment based on CBT, medication or a combination of these. METHODS: Systematic and critical review of the literature on CBT and/or pharmacological treatments of SM. Literature was sought on PubMed, Embase and Psycinfo in March 2017. RESULTS: Of the included studies, six examined CBT, seven pharmacologic treatment and two a combination of these. Using CBT 53/60 children improved symptomatically whilst respectively 55/67 and 6/7 improved using pharmacologic- and combination-treatment. CONCLUSION: Pharmacologic treatment and especially CBT showed promising results supported by some degree of evidence, which combination treatment lacks. Yet small numbers, few RCTs, heterogeneous study designs, lack of consistent measures, short treatment and follow-up periods, generally limits the evidence. This needs focus in future research.

PMID- 29447061 TI - Models to Predict Hepatitis B Virus Infection Among Patients With Cancer Undergoing Systemic Anticancer Therapy: A Prospective Cohort Study. AB - Purpose Most patients with cancer are not screened for hepatitis B virus (HBV) infection before undergoing anticancer therapy, and optimal screening strategies are unknown. We sought to develop selective HBV screening strategies for patients who require systemic anticancer therapy. Methods This prospective cohort study included adults age >= 18 years with solid or hematologic malignancies who received systemic anticancer therapy at a comprehensive cancer center during 2013 and 2014. Patients underwent hepatitis B surface antigen, hepatitis B core antibody, and hepatitis B surface antibody testing, and completed a 19-question modified Centers for Disease Control and Prevention (CDC) HBV survey. Multivariable models that predict chronic or past HBV infection were developed and validated using bootstrapping. Results A total of 2,124 patients (mean age, 58 +/- 13 years) completed the risk survey and HBV testing. Of these, 54% were women; 77% were non-Hispanic white, 11% Hispanic, 8% black, and 4% Asian; and 20% had a hematologic malignancy and 80% a solid tumor. Almost 12% were born outside the United States. The prevalence was 0.3% for chronic HBV infection and 6% for past HBV infection. Significant predictors of positive hepatitis B surface antigen or hepatitis B core antibody tests were as follows: men who had sex with men, black or Asian race, birthplace outside the United States, parent's birthplace outside the United States, household exposure to HBV, age >= 50 years, and history of injection drug use. The area under the receiver operating characteristic curve of the model on the basis of these seven predictors was 0.79 (95% CI, 0.73 to 0.82). The modified CDC survey and brief tools with fewer than seven questions yielded similar false-negative rates (0% and 0% to 0.7%, respectively). Conclusion An internally validated risk tool performed as well as the modified CDC survey; however, more than 90% of patients who completed the tool would still require HBV testing. Universal HBV testing is more efficient than risk-based screening. PMID- 29447063 TI - Introduction to the special issue on technology and neuropsychological rehabilitation. PMID- 29447064 TI - Childhood Origins of Young Adult Environmental Behavior. AB - Prospective, longitudinal analyses revealed that over a 12-year period from ages 6 to 18, individuals who grew up with mothers with more proenvironmental attitudes engaged in more proenvironmental behavior as young adults. A similar marginal association was uncovered between mothers' proenvironmental behaviors and the proenvironmental behavior of their young adult offspring. Maternal educational attainment, but not political ideology, was also associated with more proenvironmental behavior as children matured. Moreover, childhood time spent outdoors was positively associated with increased environmentally responsible behavior in young adulthood. Interestingly, one's own childhood proenvironmental behavior and attitude, at least as assessed at age 6, bear little on one's eventual proenvironmental behavior as a young adult. Finally, among this set of childhood factors, maternal education and childhood time spent outdoors were independent predictors of positive changes in environmental behavior from early childhood to young adulthood. PMID- 29447065 TI - Born criminal? Differences in structural, functional and behavioural lateralization between criminals and noncriminals. AB - Over 100 years ago Lombroso [(1876/2006). Criminal man. Durham: Duke University Press] proposed a biological basis for criminality. Based on inspection of criminals' skulls he theorized that an imbalance of the cerebral hemispheres was amongst 18 distinguishing features of the criminal brain. Specifically, criminals were less lateralized than noncriminals. As the advent of neuroscientific techniques makes more fine-grained inspection of differences in brain structure and function possible, we review criminals' and noncriminals' structural, functional, and behavioural lateralization to evaluate the merits of Lombroso's thesis and investigate the evidence for the biological underpinning of criminal behaviour. Although the body of research is presently small, it appears consistent with Lombroso's proposal: criminal psychopaths' brains show atypical structural asymmetries, with reduced right hemisphere grey and white matter volumes, and abnormal interhemispheric connectivity. Functional asymmetries are also atypical, with criminal psychopaths showing a less lateralized cortical response than noncriminals across verbal, visuo-spatial, and emotional tasks. Finally, the incidence of non-right-handedness is higher in criminal than non criminal populations, consistent with reduced cortical lateralization. Thus despite Lombroso's comparatively primitive and inferential research methods, his conclusion that criminals' lateralization differs from that of noncriminals is borne out by the neuroscientific research. How atypical cortical asymmetries predispose criminal behaviour remains to be determined. PMID- 29447066 TI - Inaugurating Rationalization: Three Field Studies Find Increased Rationalization When Anticipated Realities Become Current. AB - People will often rationalize the status quo, reconstruing it in an exaggeratedly positive light. They will even rationalize the status quo they anticipate, emphasizing the upsides and minimizing the downsides of sociopolitical realities they expect to take effect. Drawing on recent findings on the psychological triggers of rationalization, I present results from three field studies, one of which was preregistered, testing the hypothesis that an anticipated reality becoming current triggers an observable boost in people's rationalizations. San Franciscans rationalized a ban on plastic water bottles, Ontarians rationalized a targeted smoking ban, and Americans rationalized the presidency of Donald Trump, more in the days immediately after these realities became current compared with the days immediately before. Additional findings show evidence for a mechanism underlying these behaviors and rule out alternative accounts. These findings carry implications for scholarship on rationalization, for understanding protest behavior, and for policymakers. PMID- 29447068 TI - Microbial Culturomics Broadens Human Vaginal Flora Diversity: Genome Sequence and Description of Prevotella lascolaii sp. nov. Isolated from a Patient with Bacterial Vaginosis. AB - Microbial culturomics is a new subfield of postgenomic medicine and omics biotechnology application that has broadened our awareness on bacterial diversity of the human microbiome, including the human vaginal flora bacterial diversity. Using culturomics, a new obligate anaerobic Gram-stain-negative rod-shaped bacterium designated strain khD1T was isolated in the vagina of a patient with bacterial vaginosis and characterized using taxonogenomics. The most abundant cellular fatty acids were C15:0 anteiso (36%), C16:0 (19%), and C15:0 iso (10%). Based on an analysis of the full-length 16S rRNA gene sequences, phylogenetic analysis showed that the strain khD1T exhibited 90% sequence similarity with Prevotella loescheii, the phylogenetically closest validated Prevotella species. With 3,763,057 bp length, the genome of strain khD1T contained (mol%) 48.7 G + C and 3248 predicted genes, including 3194 protein-coding and 54 RNA genes. Given the phenotypical and biochemical characteristic results as well as genome sequencing, strain khD1T is considered to represent a novel species within the genus Prevotella, for which the name Prevotella lascolaii sp. nov. is proposed. The type strain is khD1T ( = CSUR P0109, = DSM 101754). These results show that microbial culturomics greatly improves the characterization of the human microbiome repertoire by isolating potential putative new species. Further studies will certainly clarify the microbial mechanisms of pathogenesis of these new microbes and their role in health and disease. Microbial culturomics is an important new addition to the diagnostic medicine toolbox and warrants attention in future medical, global health, and integrative biology postgraduate teaching curricula. PMID- 29447069 TI - After Aylan Kurdi: How Tweeting About Death, Threat, and Harm Predict Increased Expressions of Solidarity With Refugees Over Time. AB - Viral social media content has been heralded for its power to transform policy, but online responses are often derided as "slacktivism." This raises the questions of what drives viral communications and what is their effect on support for social change. We addressed these issues in relation to Twitter discussions about Aylan Kurdi, a child refugee who died en route to the European Union. We developed a longitudinal paradigm to analyze 41,253 tweets posted 1 week before the images of Aylan Kurdi emerged, the week they emerged, and 10 weeks afterward at the time of the Paris terror attacks. Tweeting about death before the images emerged predicted tweeting about Aylan Kurdi, and this, sustained by discussion of harm and threat, predicted the expression of solidarity with refugees 10 weeks later. Results suggest that processes of normative conflict and communication can be intertwined in promoting support for social change. PMID- 29447067 TI - Regulation of eukaryotic elongation factor 1 alpha (eEF1A) by dynamic lysine methylation. AB - Lysine methylation is a frequent post-translational protein modification, which has been intensively studied in the case of histone proteins. Lysine methylations are also found on many non-histone proteins, and one prominent example is eukaryotic elongation factor 1 alpha (eEF1A). Besides its essential role in the protein synthesis machinery, a number of non-canonical functions have also been described for eEF1A, such as regulation of the actin cytoskeleton and the promotion of viral replication. The functional significance of the extensive lysine methylations on eEF1A, as well as the identity of the responsible lysine methyltransferases (KMTs), have until recently remained largely elusive. However, recent discoveries and characterizations of human eEF1A-specific KMTs indicate that lysine methylation of eEF1A can be dynamic and inducible, and modulates mRNA translation in a codon-specific fashion. Here, we give a general overview of eEF1A lysine methylation and discuss its possible functional and regulatory significance, with particular emphasis on newly discovered human KMTs. PMID- 29447070 TI - Reading Your Mind While You Are Reading-Evidence for Spontaneous Visuospatial Perspective Taking During a Semantic Categorization Task. AB - Recent studies have demonstrated people's propensity to adopt others' visuospatial perspectives (VSPs) in a shared physical context. The present study investigated whether spontaneous VSP taking occurs in mental space where another person's perspective matters for mental activities rather than physical actions. Participants sat at a 90 degrees angle to a confederate and performed a semantic categorization task on written words. From the participants' point of view, words were always displayed vertically, while for the confederate, these words appeared either the right way up or upside down, depending on the confederate's sitting position. Participants took longer to categorize words that were upside down for the confederate, suggesting that they adopted the confederate's VSP without being prompted to do so. Importantly, the effect disappeared if the other's visual access was impeded by opaque goggles. This demonstrates that human adults show a spontaneous sensitivity to others' VSP in the context of mental activities, such as joint reading. PMID- 29447071 TI - A social media intervention to improve hypoglycemia management at a multicenter hospital: a quality improvement pilot for clinical nurses. AB - BACKGROUND: Hypoglycemia poses significant risk to inpatients. Nursing management of hypoglycemia is a challenge, despite established best practice guidelines. Social media is an effective tool for sharing information and could overcome barriers to clinical education at a multicenter hospital. AIMS: The purpose of this quality improvement intervention was to create and disseminate social media posts about best practices in hypoglycemia management. DESIGN: An unmatched pre and post-survey assessed nursing knowledge of hypoglycemia management. METHODS: Social media posts were created to visually outline the steps for hypoglycemia management over 2 weeks, across a nursing social media platform. We assessed the reach of the posts via Facebook and a survey. RESULTS: The posts reached 2962 users during the first week, and 1491 users the second week. CONCLUSIONS: A social media intervention can have a substantial reach and distribute information across a multicenter hospital. Additional study is needed to determine what factors could support an increase in nursing knowledge through a social media campaign. PMID- 29447072 TI - Construction and structure studies of DNA-bipyridine complexes as versatile scaffolds for site-specific incorporation of metal ions into DNA. AB - The facile construction of metal-DNA complexes using 'Click' reactions is reported here. A series of 2'-propargyl-modified DNA oligonucleotides were initially synthesized as structure scaffolds and were then modified through 'Click' reaction to incorporate a bipyridine ligand equipped with an azido group. These metal chelating ligands can be placed in the DNA context in site-specific fashion to provide versatile templates for binding various metal ions, which are exchangeable using a simple EDTA washing-and-filtration step. The constructed metal-DNA complexes were found to be thermally stable. Their structures were explored by solving a crystal structure of a propargyl-modified DNA duplex and installing the bipyridine ligands by molecular modeling and simulation. These metal-DNA complexes could have wide applications as novel organometallic catalysts, artificial ribonucleases, and potential metal delivery systems.

AB - In the yeast Saccharomyces cerevisiae, all strains possess a gene for the evolutionarily conserved POT family peptide transporter, Ptr2; however, the genes for a novel FOT family transporter were found only in some wine brewing strains. The substrate specificity of the POT and FOT family of transporters was compared. Among the naturally occurring oligopeptides that were tested, Lys-Leu and Arg-Phe were Ptr2-specific substrates. Artificial dipeptide aspartame was imported specifically through the FOT transporter, but the structurally similar Asp-Phe was a substrate of both FOT and Ptr2 transporters. Furthermore, only the FOT transporter was important for high sensitivity to an antibiotic puromycin. These results demonstrate that the POT and FOT family of transporters have distinct substrate preferences although both transporters import overlapping dipeptide substrates. Having POT and FOT transporters is advantageous for cells to acquire nutrients, but also detrimental when these cells are exposed to the toxic molecules of their substrates.

AB - INTRODUCTION: Patients diagnosed with schizophrenia display deficits in Theory of Mind (ToM) and Emotion Perception (EP) even before the appearance of full-blown symptomatology. METHODS: We evaluated ToM and EP in a male cohort consisting of 25 First Episode Psychosis (FEP) and 16 relapsed schizophrenic patients (CHRON) compared to 12 subjects in Ultra-high Risk (UHR) and 23 healthy controls (CTR). Furthermore, we measured the levels of Cortisol, Insulin like Growth Factor (IGF 1), TNF-a, TNF-b and several interleukins as potential biomarkers. RESULTS: Deficits in EP and ToM were found in FEP, CHRON patients and UHR subjects compared to CTR. The impairments in these two domains seem to follow different patterns in the course of psychosis. EP was more impaired in subjects with a longer history of symptomatology whereas there was no statistically significant difference regarding ToM. On the other hand IL-4 was the only biomarker correlated to ToM and EP scores in two different samples of our study. CONCLUSION: Social Cognition (SC) domains are impaired in patients with psychosis as well as in UHR subjects compared to healthy controls. There are differences in the progress of ToM and EP deficits in the course of psychosis. Interleukins as IL-4 could correlate to SC. PMID- 29447075 TI - Propionibacterium acnes Has Low Susceptibility to Chlorhexidine Digluconate. AB - BACKGROUND: The skin bacterium Propionibacterium acnes has been reported to be responsible for surgical site infections (SSIs). Skin disinfection before surgery therefore is of the utmost importance in the prevention of SSIs caused by skin bacteria. METHODS: We assessed the susceptibility of clinical isolates of two skin bacteria, P. acnes and Staphylococcus epidermidis, to disinfectants. RESULTS: The range of chlorhexidine digluconate (CHG) minimum inhibitory concentrations (MICs) for P. acnes isolates was 0.25-1 mcg/mL. Furthermore, the minimum bactericidal concentrations (MBCs) for a range of disinfectants were determined to evaluate their rapid bactericidal activity. The MBC range of CHG against the P. acnes isolates was 4,096->32,768 mcg/mL (MBC80 16,384 mcg/mL) after one minute of exposure and 1,024-32,768 mcg/mL (MBC80 8,192 mcg/mL) after five minutes, indicating that some strains required a CHG MBC higher than the commercial concentration of 2% (20,000 mcg/mL). In contrast, the MBCs of glutaraldehyde, sodium hypochlorite, povidone-iodine, ethanol, benzalkonium chloride, and olanexidine gluconate were all sufficiently lower than their commercial concentrations. In S. epidermidis, the MBC range of CHG was 128-1,024 mcg/mL at one minute of exposure and 4-8 mcg/mL at five minutes. CONCLUSIONS: Different skin bacteria have different susceptibilities to disinfectants. To prevent SSIs, the selected disinfectant agent and the disinfection time should have bactericidal activity toward all the bacteria that pose a risk of infection. PMID- 29447076 TI - A double-blind, placebo-controlled, randomised clinical study of the effect of pork collagen peptide supplementation on atherosclerosis in healthy older individuals. AB - We examined whether baPWV could be affected by pork collagen peptide (CP) ingestion. Seventy subjects were randomized into two groups (2.5 g/day CP and 2.5 g/day placebo). A significant reduction in baPWV was observed in the CP group compared to the placebo group. This study demonstrated that pork CP may contribute to the prevention of atherosclerosis in elderly. PMID- 29447078 TI - Effects of Peutz-Jeghers syndrome (PJS) causing missense mutations L67P, L182P, G242V and R297S on the structural dynamics of LKB1 (Liver kinase B1) protein. AB - The liver kinase B1 (LKB1) is encoded by LKB1 gene. Several pathogenic mutations of LKB1 causing Peutz-Jeghers syndrome and also cancers in breast, gastric, pancreas, and colon have been reported. The present study is focused to analyze the effects on the structural dynamics of LKB1 caused by the 4 pathogenic missense mutations (L67P, L182P, G242V, and R297S), which are reported to reduce the catalytic activity. In this study, the structural changes of LKB1 in apo- and in heterotrimeric complex (LKB1-STRADalpha-MO25alpha) form with wild and mutated LKB1 are investigated using all atomistic molecular dynamic simulation. The present study reveals that these four mutations initiate local structural distortions and the solvent accessibility of the surrounding regions of ATP binding pocket such as glycine-rich loop, alphaB and alphaC loop, activation and catalytic loops. The mutations of L67P, L182P, and G242 V induce distortions of the secondary structure of beta1-beta3 sheets, pi - pi interaction (observed between Phe204 of LKB1 and Phe243 of MO25alpha), and increase the helical properties (both helical twist and length) of the adjacent alphaH-helix, respectively. The active kinase features like the conformation of catalytic and activation loops, salt bridge and, finally, the formation of stable R- and C hydrophobic spines are also found to be perturbed by these mutations. Hence, the observed mutation-induced structural distortions fail to coordinate the essential binding nature of LKB1 with STRADalpha and MO25alpha, which eventually affects the native function of LKB1. These observations are in line with the experimentally reported reduced kinase activity of LKB1. PMID- 29447077 TI - Identification of proteins that bind to the neuroprotective agent neoechinulin A. AB - Neoechinulin A is an indole alkaloid with several biological activities. We previously reported that this compound protects neuronal PC12 cells from cytotoxicity induced by the peroxynitrite generator 3-morpholinosydnonimine (SIN 1), but the target proteins and precise mechanism of action of neoechinulin A were unclear. Here, we employed a phage display screen to identify proteins that bind directly with neoechinulin A. Our findings identified two proteins, chromogranin B and glutaredoxin 3, as candidate target binding partners for the alkaloid. QCM analyses revealed that neoechinulin A displays high affinity for both chromogranin B and glutaredoxin 3. RNA interference-mediated depletion of chromogranin B decreased the sensitivity of PC12 cells against SIN-1. Our results suggested chromogranin B is a plausible target of neoechinulin A. PMID- 29447079 TI - Flucloxacillin-induced hypokalaemia: a case report. AB - OBJECTIVE AND IMPORTANCE: Flucloxacillin is a narrow-spectrum beta-lactam antibiotic with activity against penicillinase producing staphylococci and streptococci. Severe hypokalaemia is an uncommon, but serious adverse effect in patients treated with penicillin derivates. CLINICAL PRESENTATION: We report a case of severe hypokalaemia in a patient treated with high dose intravenous flucloxacillin. CONCLUSION: This case report highlights the importance of monitoring electrolytes during treatment with high dose flucloxacillin. If severe hypokalaemia is noted during treatment, this should be considered in the differential diagnosis. PMID- 29447080 TI - Improved lower extremity pedaling mechanics in individuals with stroke under maximal workloads. AB - Background Individuals with stroke present with motor control deficits resulting in the abnormal activation and timing of agonist and antagonist muscles and inefficient movement patterns. The analysis of pedaling biomechanics provides a window into understanding motor control deficits, which vary as a function of workload. Understanding the relationship between workload and motor control is critical when considering exercise prescription during stroke rehabilitation. Objectives To characterize pedaling kinematics and motor control processes under conditions in which workload was systematically increased to an eventual patient specific maximum. Methods A cohort study was conducted in which 18 individuals with chronic stroke underwent a maximal exertion cardiopulmonary exercise test on a stationary cycle ergometer, during which pedaling torque was continuously recorded. Measures of force production, pedaling symmetry, and pedaling smoothness were obtained. Results Mean Torque increased significantly (p < 0.05) for both legs from initial to terminal workloads. Mean torque Symmetry Index, calculated for down and upstroke portions of the pedaling action, improved from 0.37(0.29) to 0.29(0.35) during downstroke (p = 0.007), and worsened during the upstroke: -0.37(0.38) to -0.62(0.46) (p < 0.001) from initial to terminal workloads. Low Torque Duration improved from initial to terminal workloads, decreasing from 121.1(52.9) to 58.1(39.6) degrees (p < 0.001), respectively. Smoothness of pedaling improved significantly from initial to terminal workloads (p < 0.001). Conclusions Improved pedaling kinematics at terminal workloads indicate that individuals with stroke demonstrate improved motor control with respect to the timing, sequencing, and activation of hemiparetic lower extremity musculature compared to lower workloads. Therapeutic prescription involving higher resistance may be necessary to sufficiently engage and activate the paretic lower extremity. PMID- 29447081 TI - Is neuropathic pain associated with cardiac sympathovagal activity changes in patients with breast cancer? AB - Objective Heart rate variability (HRV) is a good indicator of the autonomic nervous system (ANS) activity. A few studies have been conducted recently and have shown a relationship between reduced HRV and conditions that lead to neuropathic pain (NP). In this study, we aimed to investigate whether NP is associated with changes in cardiac sympathovagal activity in patients with breast cancer (BC). Methods We used the Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) questionnaire to evaluate NP in 70 patients with BC. The patients were subjected to a 24-h Holter ECG monitorization to determine heart rate variability (HRV). Standard deviation (SD) of the normal-to-normal RR intervals (SDNN), SD of the mean of the RR intervals (SDAAN), mean of the SD of the NN interval (SDNN Index), low-frequency component/high-frequency component ratio (LF/HF), and the mean heart rate of the patients were recorded. Results According to the LANSS questionnaire, 18 (25.7%) of the patients were classified as NP (+). The SDNN (P = 0.001), SDAAN (P = 0.003), and SDDN index (P = 0.007) were significantly lower in patients with NP than in patients without NP, whereas LF/HF ratio (P = 0.000) and mean heart rate were found to be significantly higher in patients with NP (P = 0.006). Conclusion According to our findings, NP (+) patients with BC had increased cardiac sympathetic activity, which was suggested to be associated with increased cardiovascular morbidity and mortality. PMID- 29447082 TI - Radiologic Measurement of Brain Swelling in Patients with Large Hemispheric Infarctions During Targeted Temperature Management. AB - Brain herniation is most often the result of severe brain swelling and can rapidly lead to death or brain death. We retrospectively identified radiologic indicators to evaluate the effects of targeted temperature management (TTM) on the extent of cerebral edema and determine the cutoff values that best predict TTM outcomes in patients with large hemispheric infarction. We retrospectively reviewed brain computed tomography (CT) scans of 21 patients with large hemispheric infarctions, who were treated with TTM. We excluded 4 patients whose CT scans were inadequate for evaluation, which left 17 patients. We divided the patients into success and failure groups. TTM failure was defined as death or the need for decompressive hemicraniectomy (DHC) after TTM. Infarction size was measured as the total restricted area in diffusion-weighted imaging that was performed on admission. CT scans were obtained on the first and second days after TTM initiation and then every 2 days. We measured septum pellucidum shifts (SPS) and pineal gland shifts (PGS) on CT scans. The median time from symptom onset to TTM initiation was 14.5 hours. Ten patients were successfully treated with TTM, six patients died, and one patient underwent a DHC. Initial infarction sizes were not significantly different between the success and failure groups (p = 0.529), but the SPS and PGS at 36-72 hours after TTM initiation were (mean SPS: 5.0 vs. 14.9 mm, p = 0.001; mean PGS: 2.3 vs. 7.9 mm, p = 0.001). The sensitivity and negative predictive value for TTM failure caused by cerebral edema (SPS >=9.25 mm and PGS >=3.70 mm) at 36-72 hours after TTM initiation were both 100%. The SPS and PGS on CT scans taken 36-72 hours after TTM initiation may help to estimate the effect of TTM on cerebral edema and guide further treatment. PMID- 29447084 TI - Binding site identification of anticancer drug gefitinib to HSA and DNA in the presence of five different probes. AB - This study was carried out to evaluate the binding interaction of gefitinib (GEF) with human serum albumin (HSA) and calf thymus DNA (ct-DNA) using fluorescence, UV-Visible, zeta potential measurements and molecular docking methods in order to understand its pharmacokinetic mechanism. By increasing the temperature, a steady decrease in Stern-Volmer quenching constants was observed for HSA binding properties; this indicates a static type of fluorescence quenching. Negative values were calculated for Gibbs free energy (DeltaG), enthalpy (DeltaH), and entropy (DeltaS) changes, indicating that the reaction is spontaneous and enthalpy-driven. Probe competitive experimental results showed that GEF contains the same binding site as warfarin and are consistent with modeling results. The zeta potential of the HSA increased with increasing GEF, which represents the presence of electrostatic interactions in the system. DNA binding properties were investigated in the presence of three probes. The experimental results showed that by increasing GEF to DNA-AO (acridine-orange) and DNA-MB (methylene-blue) system, the fluorescence intensity and absorbance spectra had no considerable change. Furthermore, with the addition of GEF to DNA, the zeta potential decreased gradually, indicating that the hydrophobic interaction between the GEF and the bases of DNA is the major factor. Thus, GEF can bind to DNA via a groove binding mode. It was also found that GEF entered into the minor groove in the A-T rich region of DNA fragment and bind via van der-Waals forces and three H-bond with double strands of DNA. This is in good agreement with experimental results. PMID- 29447083 TI - In complete SCI patients, long-term functional electrical stimulation of permanent denervated muscles increases epidermis thickness. AB - Our studies have shown that atrophic Quadriceps muscles from spinal cord injury patients suffering with permanent denervation-induced atrophy and degeneration of muscle fibers, were almost completely rescued to normal size after two years of home-based functional electrical stimulation (h-bFES). Because we used surface electrodes to stimulate the muscle, we wanted to know how the skin was affected by the treatments. Here, we report preliminary data from histological morphometry of Hematoxylin-Eosin-stained paraffin-embedded skin sections harvested from the legs of three SCI patients before and after two years of h-bFES. Despite the heterogeneity of gender and time from SCI, comparing pre vs post h-bFES in these three SCI patients, the data show that: (1) In one subject skin biopsies from both the right and left leg experienced a statistically significant increase in thickness of the epidermis after two years of H-bFES; (2) In the other two subjects, one leg showed a significant increase in epidermis thickness, while in the other leg there was either small positive or negative non-significant changes in epidermis thickness; and (3) more importantly, comparison of grouped data from the three subjects shows that there was a significant 28% increase in the thickness of the epidermis in response to two years of h-bFES rehabilitation. In conclusion, the three educational cases show a long-term positive modulation of epidermis thickness after two years of h-bFES, thus extending to skin the positive results previously demonstrated in skeletal muscle, specifically, a substantial recovery of muscle mass and contractile function after long-term h bFES. PMID- 29447085 TI - Paritaprevir/ritonavir/ombitasvir plus dasabuvir in HIV/HCV-coinfected patients with genotype 1 in real-life practice. AB - Background Data on the efficacy, safety, and concomitant use with other drugs of the combination ritonavir-boosted paritaprevir/ombitasvir plus dasabuvir (PrOD) in HIV/HCV-coinfected patients in real life are limited. The objectives of this study were to analyze these topics in HIV/HCV-coinfected subjects bearing HCV genotype 1 (GT1). Methods One hundred and eighty-two HIV/HCV-coinfected patients with GT1 (87 1a, 71 1b, 23 other) treated with PrOD, plus ribavirin (RBV) in 119 cases, in routine clinical practice were analyzed. The main variable of efficacy was sustained virological response (SVR) 12 weeks after completing therapy in an intention-to-treat (ITT) analysis and that of safety treatment discontinuation because of adverse effects. Factors associated with SVR were analyzed with a modified ITT (mITT) strategy. Results One hundred and seventy-two (94%) patients attained SVR, 3 (2%) experienced a relapse and two (1%) discontinued therapy due to adverse events. The rates of SVR in subjects with GT 1a and 1b by mITT were, respectively, 97% and 98%. Sixty-five (98%) out of 66 patients with cirrhosis and 107 (98%) out of 110 (p = 1) non-cirrhotics achieved SVR. Fifty-five (95%) patients on concomitant darunavir therapy developed SVR vs. 117 (99%) (p = 0.105) of those without DRV. RBV dose was reduced in 13 (11%) patients and permanently discontinued in 2 (2%), with no impact on SVR. Conclusions PrOD is highly effective and well tolerated in HIV/HCV-coinfected patients with GT1 in routine clinical practice. RBV is often required. However, RBV dose reduction or discontinuation is uncommonly needed and do not impair the SVR rate. PMID- 29447086 TI - Vitamin D down-regulates the expression of some Th17 cell-related cytokines, key inflammatory chemokines, and chemokine receptors in experimental autoimmune encephalomyelitis. AB - OBJECTIVES: A spectrum of immunomodulatory properties was attributed to vitamin D (VD). Here, the VD effects on expression of some Th17 cell- related cytokines, chemokines and chemokine receptors were investigated in experimental autoimmune encephalomyelitis (EAE). METHODS: One group of C57BL/6 mice, considered as healthy group, was treated with phosphate buffered saline (PBS). EAE was induced in other three groups and treated from day +3 to +30 with PBS, olive oil (VD vehicle) or 200 ng of VD. At day 31, the expression of interleukin-17 (IL-17), IL 23, chemokine (C-C motif) ligand 20 (CCL20), CCL22, CC chemokine receptor 4 (CCR4) and CCR6 in spinal cord and serum IL-17 and IL-23 levels were measured by real-time PCR and ELISA, respectively. RESULTS: The expression of IL-17, IL-23 P19, IL-23 P40, CCL20, CCL22 and CCR4 in spinal cord and serum IL-17 and IL-23 levels in PBS-administrated EAE mice were significantly increased compared with healthy group. In EAE mice treated with VD, the expression of aforementioned parameters was significantly reduced in comparison with PBS-administrated EAE mice. CONCLUSION: VD down-regulates the expression of some inflammatory cytokines, chemokines and chemokine receptors in EAE mice. The possible therapeutic potential of VD in multiple sclerosis can be considered in future investigation. PMID- 29447087 TI - A preliminary survey of Chlamydia psittaci genotypes from native and introduced birds in New Zealand. AB - AIM: To describe the Chlamydia psittaci genotypes in samples from native and introduced birds from New Zealand by analysis of the sequence variation of the ompA gene. METHODS: DNA was extracted from samples collected from a non-random sample of birds; either swabs from live asymptomatic birds or birds with clinical signs, or formalin-fixed, paraffin-embedded (FFPE) samples from historical post mortem cases. The presence of C. psittaci in all samples had been confirmed using a quantitative PCR assay. The C. psittaci ompA gene was amplified and sequenced from samples from 26 native and introduced infected birds comprising 12 different species. These sequences were compared to published available C. psittaci genotypes. RESULTS: Genotypes A and C of C. psittaci were identified in the samples. Genotype A was identified in samples from nine birds, including various native and introduced species. Genotype C was identified in samples from 16 different waterfowl species, and a mixed infection of both genotypes was found in a kaka (Nestor meridionalis). In native birds, C. psittaci infection was confirmed in seven new host species. CONCLUSIONS AND CLINICAL RELEVANCE: Two genotypes (A and C) of C. psittaci were found in samples from a wider range of both native and introduced species of birds in New Zealand than previously reported. Both genotypes have been globally associated with significant disease in birds and humans. These initial results suggest the host range of C. psittaci in New Zealand birds is under-reported. However, the prevalence of C. psittaci infection in New Zealand, and the associated impact on avian and public health, remains to be determined. There are biosecurity implications associated with the importation of birds to New Zealand if there is a limited diversity of C. psittaci genotypes present. PMID- 29447088 TI - Increasing incidence and survival of head and neck cancers in Denmark: a nation wide study from 1980 to 2014. AB - BACKGROUND: The purpose of the study was to determine trends in age-adjusted incidence rates (AAIR) and survival probability in head and neck cancers (HNCs) in the Danish population from 1980 to 2014. MATERIAL AND METHODS: All patients registered with HNC in the nationwide Danish Cancer Registry from 1980 to 2014 were included. We evaluated the AAIR per 100,000 and the average annual percent change (AAPC). The relative survival probability at 5 years was calculated in relation to gender, anatomical location and histology, and we constructed age period-cohort models of incidence. RESULTS: About 34,606 patients were included (64.7% men). The AAIR increased from 9.1 per 100,000 in 1980 to 17.4 per 100,000 in 2014 with an AAPC of 2.1%. The greatest incidence increase was observed in oropharyngeal cancer (AAPC: 5.4%) followed by hypopharyngeal cancer (AAPC: 4.2%). Adenocarcinomas had the highest AAPC (5.0%) followed by squamous cell carcinomas (AAPC: 2.0%). The AAPC was significantly higher in women (2.4%) compared with men (1.6%). For all HNC patients, the relative survival at 5 years rose significantly from 49.0% in 1980-1984 to 62.4% in 2010-2014. Women had a significantly higher survival than men with a relative survival of 61.7% compared to 50.0% in men. Laryngeal cancer had the best survival probability of cancers in the upper aerodigestive tract with hypopharyngeal cancer having the poorest survival. CONCLUSION: This nation-wide study showed a significant rise in incidence of HNC for men and women along with a significant increase in relative survival. Oropharyngeal cancer had the highest increase in incidence followed by hypopharyngeal cancer which showed the poorest survival of HNCs. PMID- 29447089 TI - Aflibercept Versus Bevacizumab and/or Ranibizumab for Recurrent Macular Edema Secondary to Central Retinal Vein Occlusion. AB - PURPOSE: To compare functional and anatomic outcomes of treatment with intravitreal aflibercept versus bevacizumab and/or ranibizumab in patients with recurrent macular edema (ME) secondary to central retinal vein occlusion (CRVO). METHODS: Retrospective, comparative case series of patients with recurrent ME in the setting of CRVO. Patients with recurrent ME received treatment with aflibercept (Group 1, G1) or bevacizumab and/or ranibizumab (Group 2, G2). Primary outcome measures were best-corrected visual acuity (BCVA) and central foveal thickness (CFT). RESULTS: Of the 20 eyes (20 patients) with recurrent ME included in the study, 9 received aflibercept (G1) and 11 received bevacizumab and/or ranibizumab (G2). Median BCVA at recurrence of ME and at most recent follow-up was 20/60 (G1) and 20/80 (G2) and 20/40 (G1) and 20/50 (G2, P > 0.05 for all comparisons), respectively. Median CFT at recurrence of ME and at most recent follow-up was 492 MUm (G1) and 448 MUm (G2) and 291 MUm (G1) and 295 MUm (G2, P > 0.05 for all comparisons), respectively. Complete resolution of ME for at least 4 months was found in 78% (G1) and 55% (G2) of patients with a median injection free interval of 11 (G1) and 13 (G2) months (P > 0.05). CONCLUSIONS: In patients with recurrent ME secondary to CRVO, there was improvement in BCVA and CFT in all groups, although patients treated with aflibercept showed a trend toward better anatomical outcomes decreased need for recurrent injections. PMID- 29447091 TI - Obesity in pregnancy: a comparison of four national guidelines. AB - BACKGROUND: Obesity in pregnancy has become one of the most important challenges in obstetrical care given its prevalence and potential adverse impact on both mother and fetus. The primary objective of this descriptive review is to identify common themes and distinctions within the current recommendations for maternal obesity in the most updated version of four published national guidelines. METHODS: We reviewed the following guidelines for obesity in pregnancy: American College of Obstetricians and Gynecologists (ACOG) 2015, Royal Australian and New Zealand College of Obstetricians and Gynecologists (RANZCOG) 2013, Royal College of Obstetrics and Gynecology (RCOG) 2010, and Society of Obstetrics and Gynecologists of Canada (SOGC) 2010. RESULTS: There were no major contradictions between the guidelines, however, variations did exist. Recognition of overweight and obese populations prenatally was uniformly emphasized, so that appropriate nutrition and exercise counseling could be provided prior to pregnancy. Obesity in pregnancy was consistently defined as a body mass index of 30 kg/m2 or more, and weight gain recommendations were in line with the Institute of Medicine guidelines. Counseling patients regarding the specific maternal and fetal complications in pregnancy, delivery, and postpartum which are associated with obesity was consistently emphasized. Most guidelines recommended early screening for gestational diabetes, however, specific details were not provided. All guidelines stressed the importance of available resources in clinics and the operating room specific to the obese population. Disparities were found regarding recommendations for high-dose folic acid, vitamin D supplementation, and low-dose aspirin. Thromboprophylaxis is a matter of debate, with most guidelines recommending use on an individual patient basis. CONCLUSIONS: In general, the guidelines emphasized the importance of counseling women regarding the risks associated with obesity in pregnancy, and stressed the necessity of screening for these adverse outcomes. Initiatives to develop common terminology and reporting of outcomes in women's health are important for the development of cohesive and uniform recommendations for patient care. Disparities existed with respect to management strategies and where the further research and systematic reviews should be targeted, to allow clinicians to provide an appropriate obstetrical care pathway for obese women. PMID- 29447092 TI - Evolution of muscular fatigue in periscapular and rotator cuff muscles during isokinetic shoulder rotations. AB - To this day, how shoulder muscles react to a strong fatigue stimulus during dynamic shoulder rotations remains unknown. The aims of this study were to assess the effect of repeated maximal internal-external isokinetic shoulder rotations on shoulder strength and muscle activity. Twenty-four individuals completed a 50 repetition fatiguing isokinetic protocol while electromyography was recorded on eleven muscles of the shoulder girdle. Time-frequency transformation and an ANOVA model using statistical parametric mapping methods were used to analyze shifts in instantaneous median frequency (MDF) between each 10-repetition Blocks. Peak torques decreased in both internal and external rotation (P < 0.01) by 24.8% on average which indicated the presence of fatigue. Significant decrease in MDF (P < 0.01) was observed for pectoralis, middle deltoid, upper, middle and lower trapezius, infraspinatus and subscapularis muscles. The observed fatigue to the periscapular and rotator cuff muscles suggests that shoulder stability could be compromised during repeated shoulder rotations, which could underlie the increased risk of scapular dyskinesis and shoulder impingement during fatiguing tasks. The present study provides a deeper understanding on the manifestations of fatigue within muscles of the shoulder girdle and the results could be applied toward improvements in athlete shoulder injury prevention and rehabilitation programs. PMID- 29447093 TI - Drug-Addicted Oncology Practice: The Drug Test. AB - PURPOSE: The buy-and-bill model of pharmaceuticals has been an economic reality for medical oncology practices for more than 30 years. Infusion services, once just a supportive service, grew exponentially in most practices between 1991 and 2000, to the point at which revenue from these services created a high, which made all things possible, including care of underinsured or uninsured patients. This altered state was further enhanced in the early part of this past decade when the introduction of high-cost chemotherapeutics and biologic agents created the euphoria of big business and a true dollar distortion for even the smallest oncology practice. RESULTS: In 2005, government and payer intervention forced average wholesale price to average sales price conversion to reduce the drug effect. Concurrently, payer scrutiny of utilization and medical necessity with further dose reductions, equating to margins, led many practices to experience painful drug withdrawal symptoms. Despite the enormous financial risk for unreimbursed expense and acknowledged spiraling decline of drug margins of greater than 30% since 2002, the seductive possibility of a financial fix keeps the practices hooked. CONCLUSION: Many practices will make poor financial choices and will gamble with their financial health by consuming precious resources to support the habit. We propose the drug test: Run your practice financials without drugs. Can you cover the total practice expense without drugs? If not, determine your level of dependency on the drug margin, and adjust your service lines and salaries accordingly. We issue the following warning: Drug dependencies may be hazardous to the financial health of your organization. PMID- 29447094 TI - Reduction in Chemotherapy Mixing Errors Using Six Sigma: Illinois CancerCare Experience. AB - PURPOSE: Chemotherapy mixing errors (CTMRs), although rare, have serious consequences. Illinois CancerCare is a large practice with multiple satellite offices. The goal of this study was to reduce the number of CTMRs using Six Sigma methods. PATIENTS AND METHODS: A Six Sigma team consisting of five participants (registered nurses and pharmacy technicians [PTs]) was formed. The team had 10 hours of Six Sigma training in the DMAIC (ie, Define, Measure, Analyze, Improve, Control) process. Measurement of errors started from the time the CT order was verified by the PT to the time of CT administration by the nurse. Data collection included retrospective error tracking software, system audits, and staff surveys. RESULTS: Root causes of CTMRs included inadequate knowledge of CT mixing protocol, inconsistencies in checking methods, and frequent changes in staffing of clinics. Initial CTMRs (n = 33,259) constituted 0.050%, with 77% of these errors affecting patients. The action plan included checklists, education, and competency testing. The postimplementation error rate (n = 33,376, annualized) over a 3-month period was reduced to 0.019%, with only 15% of errors affecting patients. Initial Sigma was calculated at 4.2; this process resulted in the improvement of Sigma to 5.2, representing a 100-fold reduction. Financial analysis demonstrated a reduction in annualized loss of revenue (administration charges and drug wastage) from $11,537.95 (Medicare Average Sales Price) before the start of the project to $1,262.40. CONCLUSION: The Six Sigma process is a powerful technique in the reduction of CTMRs.

AB - PURPOSE: In Ontario, health care spending has grown to 45% of total government expenditures. In a public health care system, changes in demographics and the emergence of innovative technologies challenge our ability to adapt to evolving patient needs. To maintain a high standard of clinical effectiveness, there is a need to identify opportunities to improve health care delivery. This study was structured to meet the following objectives: to understand the operating room (OR) inventory practices at a tertiary academic hospital, to mathematically model this process to ascertain service levels based on changes in inventory and demand, and to define the appropriate level of reusable inventory for open and laparoscopic colorectal surgery. METHODS: We retrospectively reviewed OR throughput for all cases of colorectal cancer from January 1, 2010, to January 31, 2011. The process flow of OR instrumentation was studied to understand delays in the provision of inventory. Combining total surgeries performed with surgeon specific instrument preferences generated daily instrument demand. We fitted parametric demand distributions for two instrument sets for major colon resections. Markovian models were used to estimate the distribution of available inventory and the likelihood of insufficient instruments on any given day. RESULTS: We reviewed 1,458 cases, 39.5% of which involved major open surgery, whereas 26.2% involved laparoscopic surgery. Demand for open and laparoscopic instrument sets was observed to fit binomial (20, 0.15) and Poisson (1.41) distributions, respectively. On the basis of these curves, we estimated the probability distribution of the in-stock inventory and, subsequently, the probability that demand would exceed supply on any given day ( Table 1 ). In particular, with 10 open and six laparoscopic sets currently owned by the institution, the probabilities that there would be insufficient inventory were 3.02% and 2.17%, respectively. [Table: see text] Conclusion: This analysis will guide purchasing decisions based on desired service levels and forecasted changes in demand. Furthermore, by ensuring that demand is being serviced, this analysis will help to curb loss of revenue, decrease wait times, and limit potential patient morbidity. Strategic purchasing can also reduce excessive inventory and therefore minimize shrinkage and obsolescence and increase working capital and institutional flexibility. PMID- 29447096 TI - Countering the Misincentivization of Cancer Medicine by Real-Time Personal Professional Education. AB - PURPOSE: In the United States, public and private payer misincentivization of medical care and the invisibility of costs to the consumers of that care have conspired to create unsustainable growth in health care expenditure that undermines our economy, diminishes our productivity, and limits our international competitiveness. Cancer medicine provides a small yet salient example. On average, Medicare reimburses oncologists 6% above the average acquisition price for essential anticancer agents and supportive therapies. The costs of these agents vary across a stunning five orders of magnitude, from a few dollars to more than $400,000 per course of treatment. The profitability to providers varies across approximately four orders of magnitude, from cents to thousands of dollars per treatment. National guidelines (National Comprehensive Cancer Network [NCCN], American Society of Clinical Oncology [ASCO]) help providers select the most effective therapies without regard for cost. METHODS: We created an oncologist-to oncologist professional education program to help cancer physicians optimally use expensive long-acting white blood cell growth factors, in accordance with these national guidelines. We then compared their use across a population of approximately 97,000 Medicare members before and after our intervention. Baseline use was recorded over two consecutive quarters (2009 to 2010). In March 2010, our oncologists initiated real-time discussions with the oncologists of 22 separate groups if these agents were ordered for use with regimens that placed patients at less than 10% risk of febrile neutropenia, according to NCCN guidelines. Neither NCCN nor ASCO recommend the routine use of these agents in this low-risk group. The care of 82 such patients was thoroughly discussed in the following 6 months. RESULTS: The monthly costs for these agents decreased by more than 50% by the final month of our intervention, although savings began immediately, reducing costs by more than $150,000 per quarter. No episode of febrile neutropenia was recorded in any patient in the intervention group. These savings generalize to the entire Medicare population at $30 million each month. CONCLUSION: We conclude that personal, oncologist-to-oncologist, real-time professional education will favorably modify oncologic prescribing behavior and can do so with significant immediate savings at no risk to patients with cancer. PMID- 29447097 TI - Wise Investment? Modeling Industry Profitability and Risk of Targeted Chemotherapy for Incurable Solid Cancers. AB - PURPOSE: Pharmaceutical development involves substantial financial risk. This risk, rising development costs, and the promotion of continued research and development have been cited as major drivers in the progressive increase in drug prices. Currently, cost-effective analyses are being used to determine the value of treatment. However, cost-effective analyses practically function as a threshold for value and do not directly address the rationale for drug prices. We set out to create a functional model for industry price decisions and clarify the minimum acceptable profitability of new drugs. METHODS: Assuming that industry should only invest in profitable ventures, we employed a linear cost-volume profit breakeven analysis to equate initial capital investment and risk and post drug-approval profits, where drug development represents the bulk of investment. A Markov decision analysis model was also used to define the relationships between investment events risk. A systematic literature search was performed to determine event probabilities, clinical trial costs, and total expenses as inputs into the model. Disease-specific inputs, current market size across regions, and lengths of treatment for cancer types were also included. RESULTS: With development of single novel chemotherapies costing from $802 to $1,042 million (2002 US dollars), pharmaceutical profits should range from $4.3 to $5.2 billion, with an expected rate of return on investment of 11% annually. However, diversification across cancer types for chemotherapy can reduce the minimum required profit to less than $3 billion. For optimal diversification, industry should study four tumor types per drug; however, nonprofit organizations could tolerate eight parallel development tracks to minimize the risk of development failure. Assuming that pharmaceutical companies hold exclusive rights for drug sales for only 5 years after market approval, the minimum required profit per drug per month per patient ranges from $294 for end-stage lung cancer to $3,231 for end-stage renal cell carcinoma. CONCLUSION: Pharmaceutical development in oncology is costly, with substantial risk, but is also highly profitable. Minimum acceptable profits per drug per month of treatment per patient vary with prevalence of disease, but they should be less than $5,000 per month of treatment in the developed world. Minimum acceptable profits may be lower for treatments with additional efficacy in the earlier stages of a tumor type. However, this type of event could not be statistically modeled. PMID- 29447098 TI - Achieving Meaningful Use and Operational Efficiency. AB - PURPOSE: The Centers for Medicare and Medicaid Services (CMS), through the Electronic Health Record (EHR) Incentive Program, are providing incentive payments to eligible professionals as they demonstrate meaningful use of certified EHR technology. Eligible professionals can receive up to $44,000 over a 5-year period for Medicare participation if they successfully demonstrate the ability to automatically generate, transmit, and meet thresholds for specific reporting elements from the EHR. Meeting the meaningful use requirement involves a reorganization of workflow within the clinical setting so that the data elements necessary to produce the relevant measurements are documented in the electronic medical record (EMR) as they are delivered. A by-product of this is operational efficiency improvement in three areas: coordination of data input throughout the care team to reduce or remove bottlenecks, assignment of responsibility for specific activity, and real-time objective monitoring of the work process. METHODS: Using the reporting system functionality of a certified EMR deployed in a two-physician medical oncology practice at the New London Cancer Center, the objective measurement of the ability of each of the eligible providers in the clinic to improve their individual MU scores was tracked. Analysis of the progress of each provider revealed gaps. Process issues were identified by work group: secretaries, laboratory preparation and phlebotomy staff, nurses, and clinicians. The designated physician leader met with each group to discuss the sections relevant to that particular group. RESULTS: By discovering and addressing work processes that were not utilizing the ability of the EHR to capture and document (ie, meaningful use of the EHR), rapid progress that affected all of the eligible providers and all patients cared for was made. Changes resulted in increased clarity of clinical and administrative responsibilities during patient processing and clinical care provision. Meaningful use attestation was completed in 14 weeks. CONCLUSION: Completion of the documentation necessary to meet the requirements of the EHR Incentive Program led to the discovery of systemic inefficiencies in administrative and clinical workflows. Addressing these bottlenecks, along with using the reporting capability of the EHR to measure the impact of workflow changes, enabled the administrative and care teams to make changes quickly and effectively. The certified EHR provided guidance and status-reporting capabilities that allowed the practice to achieve the meaningful use requirement. PMID- 29447099 TI - Keeping Pace With Oral Chemotherapy. AB - PURPOSE: Although the rising number of oral chemotherapy agents offers many patients with cancer a more convenient and less invasive treatment option compared with infusion therapy, multiple risks and challenges have been identified with the oral regimen, including dosing errors, drug interactions, and nonadherence or overadherence. Until recently, cancer care providers had maintained a considerable amount of control, including the certainty that the right drug was being administered in the right dose, via the right route, at the right time, and to the right patient-all of which were meticulously documented in patient records. In contrast, oral chemotherapy takes much of the control out of the clinician's hands and places tremendous responsibility on the patient, raising a number of adherence and control issues. Studies regarding oral hormonal therapy for breast cancer have described adherence rates ramping down from 83% to 77% within the first 2 years of therapy. These figures continue to decrease over time to a range of 50% to 64% within 4 to 5 years. On the basis of these data and a literature review, we developed a program to promote adherence to oral anticancer protocols. METHODS: Our team took a proactive, team-focused approach and established protocols at a time when oral chemotherapies were still at a low volume. In addition to infrastructures, policies, and procedures promoting collaborative communications among physicians, nurses, and pharmacists, we developed an in-depth educational component that provides the linchpin for ensuring an effective oral chemotherapy program. Our program focuses on three key pillars: education, communication, and follow-up. Our project team first conducted an inclusive review of available literature, with the objective of designing processes that would help our program directly address existing risks and challenges. Then we introduced concepts for the formalized program to our cancer center physicians, whose support was paramount to successful implementation. The next step was to start the program with a mandatory in service for all clinical staff, which included a presentation of the research evidence that prompted the creation of this model for oral chemotherapy. To enhance patient understanding, our team provides printed materials, individualized calendars, and in some cases preloaded pillboxes to assist patients. Concurrently, our nurses provide weekly telephone intervention for the second and third months and monthly phone interventions thereafter. Communication is key to the success of the program. This includes the use of a translation service to ensure effective communication with all non-English-speaking patients. We intervene early for those patients with financial barriers and offer a variety of referrals and resources for emotional, nutritional, and patient support services, including transportation issues. RESULTS: Since the inception of the program, the in-service has been incorporated into our new employee orientation. At the same time, a growing number of cancer center physicians are embracing the program. The program has received the attention of the Oncology Roundtable, which developed a Webinar around the topic, and been described in a feature article in an oncology journal. Finally, our team has been tapped to educate other pharmacists regarding oral agents, toxicity profiles, and safe handling. CONCLUSION: By combining safeguards, patient education strategies, intensive follow-up, and a system of effective checks and balances, our center is taking significant steps to maximize patient safety and oral chemotherapy treatment effectiveness, while keeping pace with the rapidly occurring changes in oncology practice. PMID- 29447100 TI - Extending Oncology Clinical Services to Rural Areas of Texas Via Teleoncology. AB - : Abstracts Purpose: For patients in rural Texas, accessing cancer specialists is quite challenging. Texas has many remote areas without community-based cancer care, requiring patients to travel long distances for specialized cancer professional consultations and services. An anticipated shortage of medical oncology expertise will exacerbate this situation. The advent of telemedicine tools has created an opportunity to easily extend specialized cancer services to underserved populations of patients with cancer in Texas. However, more research is needed to explore how well telemedicine tools will be accepted and used by both patients and oncologists alike. Data suggesting that teleoncology services are well accepted and liked by patients and health care professionals would provide a basis for expanding this method of delivering care. If effective, telemedicine tools could help patients with cancer in rural Texas, and throughout the United States, access the same quality of cancer care as their counterparts living in urban areas. METHODS: This pilot study will compare the effectiveness and reliability of remote oncologic clinical evaluations conducted via a telemedicine application with the traditional method of onsite evaluations in a private practice setting in rural East Texas. Patient and physician satisfaction with the clinical consultations and their perceptions of the telemedicine application will be assessed using a questionnaire administered at the conclusion of the clinical meetings. RESULTS: Initial results indicate high patient and physician satisfaction scores as well as high reliability and adequacy of the equipment and technology being used. CONCLUSION: Both patients and physicians are highly satisfied with the quality of teleoncology examinations and express openness to this method of delivering care. PMID- 29447101 TI - Development by a Large Integrated Health Care System of an Objective Methodology for Evaluation of Medical Oncology Service Sites. AB - PURPOSE: Aurora Health Care (AHC) is the largest health care system in Wisconsin, with 14 acute care hospitals. In early 2010, a group of 18 medical oncologists became affiliated with AHC. This affiliation added 13 medical oncology infusion clinics to our existing 12 sites. In the era of health care reform and declining reimbursement, we need an objective method and criteria to evaluate our 25 outpatient medical oncology sites. We developed financial, clinical, and strategic tools for the evaluation and management of our cancer subservice lines and outpatient sites. The key to our success has been the direct involvement of stakeholders with a vested interest in the services in the selection of the criteria and evaluation process. METHODS: We developed our objective metrics for evaluation based on strategic, financial, operational, and patient experience criteria. Strategic criteria included: population trends, full-time equivalent (FTE) medical oncologists/primary care physicians, FTE radiation oncologists, FTE oncologic surgeons, new annual cases of patients with cancer, and market share trends. Financial criteria per site included: physician work relative value units, staff FTE by type, staff salaries, and profit and loss. Operational criteria included: facility by type (clinic v hospital based), hours of operation, and facility detail (eg, No. of chairs, No. of procedure and examination rooms, square footage). Patient experience criteria included: nursing model primary/nurse navigators, multidisciplinary support at site, Press Ganey (South Bend, IN; health care performance improvement company) results, and employee engagement score. RESULTS: The outcome of our data analysis has resulted in the development of recommendations for AHC senior leadership and geographic market leadership to consider the consolidation of four sites (phase one, four sites; phase two, two sites) and priority strategic sites to address capacity issues that limit growth. The recommendations if implemented would result in significant cost savings, currently being quantified as a result of consolidation and improved efficiency. A reinvestment of these cost savings would be required to address facility expansion and program enhancement to maximize patient centered expert care consistently across all of our remaining sites of service.

PMID- 29447105 TI - Multi-muscle electrical stimulation and stand training: Effects on standing. AB - OBJECTIVE: To examine the biomechanical and neuromuscular effects of a longitudinal multi-muscle electrical stimulation (submaximal intensities) training of the lower limbs combined with/without activity-based stand training, on the recovery of stability and function for one individual with spinal cord injury (SCI). DESIGN: Single-subject, longitudinal study. SETTING: Neuroplasticity laboratory. PARTICIPANT: A 34-year-old male, with sensory- and motor-complete SCI (C5/C6). INTERVENTIONS: Two consecutive interventions: 61 hours of supine, lower-limb ES (ES-alone) and 51 hours of ES combined with stand training using an overhead body-weight support system (ST + ES). OUTCOME MEASURES: Clinical measures, trunk stability, and muscle activity were assessed and compared across time points. Trunk Stability Limit (TSL) determined improvements in trunk independence. RESULTS: Functional clinical values increased after both interventions, with further increases post ST + ES. Post ES-alone, trunk stability was maintained at 81% body-weight (BW) loading before failure; post ST + ES, BW loading increased to 95%. TSL values decreased post ST + ES (TSLA/P=54.0 kg.cm, TSLM/L=14.5 kg.cm), compared to ES-alone (TSLA/P=8.5 kg.cm, TSLM/L=3.9 kg.cm). Trunk muscle activity decreased post ST + ES training, compared to ES-alone. CONCLUSION: Neuromuscular and postural trunk control dramatically improved following the multi-muscle ES of the lower limbs with stand training. Multi-muscle ES training paradigm of the lower limb, using traditional parameters, may contribute to the functional recovery of the trunk. PMID- 29447107 TI - Vitamin D status and risk of dementia and Alzheimer's disease: A meta-analysis of dose-response. AB - OBJECTIVE: We aimed to test the dose-response association of serum 25(OH)D and risk of dementia and Alzheimer's disease (AD). METHODS: We performed a systematic search of PubMed and Scopus from database inception up to September 2017. Longitudinal cohort studies reporting risk estimates of incident dementia or AD in the general population, and for three or more quantitative categories of serum 25(OH)D were included. Pooled hazard ratios (HRs) were calculated using fixed effects/random-effects models. RESULTS: Seven prospective cohort studies and one retrospective cohort study (total n = 28,354) involving 1953 cases of dementia and 1607 cases of AD were included. The pooled HRs of dementia and AD were 1.09 (95%CI: 0.95, 1.24) and 1.19 (95%CI: 0.96, 1.41) for vitamin D insufficiency (10 20 ng/ml), and 1.33 (95%CI: 1.08, 1.58) and 1.31 (95%CI: 0.98, 1.65) for deficiency (<10 ng/ml), respectively. The lower risk of dementia was observed at serum 25(OH)D of ~25 ng/ml, whereas the risk of AD decreased continuously along with the increase of serum 25(OH)D up to ~35 ng/ml. CONCLUSION: Higher levels of serum 25(OH)D was associated with a lower risk of dementia and AD, but we have no conclusive evidence regarding serum 25(OH)D levels of >35 ng/ml. PMID- 29447108 TI - Introducing a simple model system for binding studies of known and novel inhibitors of AMPK: a therapeutic target for prostate cancer. AB - Prostate cancer (PC) is one of the leading cancers in men, raising a serious health issue worldwide. Due to lack of suitable biomarker, their inhibitors and the platform for testing those inhibitors result in poor prognosis of PC. AMP activated protein kinase (AMPK) is a highly conserved protein kinase found in eukaryotes that is involved in growth and development, and also acts as a therapeutic target for PC. The aim of the present study is to identify novel potent inhibitors of AMPK and propose a simple cellular model system for understanding its biology. Structural modelling and MD simulations were performed to construct and refine the 3D models of Dictyostelium and human AMPK. Binding mechanisms of different drug compounds were studied by performing molecular docking, molecular dynamics and MM-PBSA methods. Two novel drugs were isolated having higher binding affinity over the known drugs and hydrophobic forces that played a key role during protein-ligand interactions. The study also explored the simple cellular model system for drug screening and understanding the biology of a therapeutic target by performing in vitro experiments. PMID- 29447106 TI - Challenges of site-specific selenocysteine incorporation into proteins by Escherichia coli. AB - Selenocysteine (Sec), a rare genetically encoded amino acid with unusual chemical properties, is of great interest for protein engineering. Sec is synthesized on its cognate tRNA (tRNASec) by the concerted action of several enzymes. While all other aminoacyl-tRNAs are delivered to the ribosome by the elongation factor Tu (EF-Tu), Sec-tRNASec requires a dedicated factor, SelB. Incorporation of Sec into protein requires recoding of the stop codon UGA aided by a specific mRNA structure, the SECIS element. This unusual biogenesis restricts the use of Sec in recombinant proteins, limiting our ability to study the properties of selenoproteins. Several methods are currently available for the synthesis selenoproteins. Here we focus on strategies for in vivo Sec insertion at any position(s) within a recombinant protein in a SECIS-independent manner: (i) engineering of tRNASec for use by EF-Tu without the SECIS requirement, and (ii) design of a SECIS-independent SelB route. PMID- 29447109 TI - Sepsis 2018: Definitions and Guideline Changes. AB - BACKGROUND: Sepsis is a global healthcare issue and continues to be the leading cause of death from infection. Early recognition and diagnosis of sepsis is required to prevent the transition into septic shock, which is associated with a mortality rate of 40% or more. DISCUSSION: New definitions for sepsis and septic shock (Third International Consensus Definitions for Sepsis and Septic Shock [Sepsis-3]) have been developed. A new screening tool for sepsis (quick Sequential Organ Failure Assessment [qSOFA]) has been proposed to predict the likelihood of poor outcome in out-of-intensive care unit (ICU) patients with clinical suspicion of sepsis. The Surviving Sepsis Campaign Guidelines were recently updated and include greater evidence-based recommendations for treatment of sepsis in attempts to reduce sepsis-associated mortality. This review discusses the new Sepsis-3 definitions and guidelines. PMID- 29447110 TI - Time- and polarity-dependent proteomic changes associated with homeostatic scaling at central synapses. AB - In homeostatic scaling at central synapses, the depth and breadth of cellular mechanisms that detect the offset from the set-point, detect the duration of the offset and implement a cellular response are not well understood. To understand the time-dependent scaling dynamics we treated cultured rat hippocampal cells with either TTX or bicucculline for 2 hr to induce the process of up- or down scaling, respectively. During the activity manipulation we metabolically labeled newly synthesized proteins using BONCAT. We identified 168 newly synthesized proteins that exhibited significant changes in expression. To obtain a temporal trajectory of the response, we compared the proteins synthesized within 2 hr or 24 hr of the activity manipulation. Surprisingly, there was little overlap in the significantly regulated newly synthesized proteins identified in the early- and integrated late response datasets. There was, however, overlap in the functional categories that are modulated early and late. These data indicate that within protein function groups, different proteomic choices can be made to effect early and late homeostatic responses that detect the duration and polarity of the activity manipulation. PMID- 29447112 TI - Evidence that cell surface localization of serine protease activity facilitates cleavage of the protease activated receptor CDCP1. AB - The cellular receptor CUB domain containing protein 1 (CDCP1) is commonly elevated and functionally important in a range of cancers. CDCP1 is cleaved by serine proteases at adjacent sites, arginine 368 (R368) and lysine 369 (K369), which induces cell migration in vitro and metastasis in vivo. We demonstrate that membrane localization of serine protease activity increases efficacy of cleavage of CDCP1, and that both secreted and membrane anchored serine proteases can have distinct preferences for cleaving at CDCP1-R368 and CDCP1-K369. Approaches that disrupt membrane localization of CDCP1 cleaving serine proteases may interfere with the cancer promoting effects of CDCP1 proteolysis. PMID- 29447113 TI - The AGO proteins: an overview. AB - Small RNAs govern almost every biological process in eukaryotes associating with the Argonaute (AGO) proteins to form the RNA-induced silencing complex (mRISC). AGO proteins constitute the core of RISCs with different members having variety of protein-binding partners and biochemical properties. This review focuses on the AGO subfamily of the AGOs that are ubiquitously expressed and are associated with small RNAs. The structure, function and role of the AGO proteins in the cell is discussed in detail. PMID- 29447111 TI - Free light chains of immunoglobulins in patients with systemic sclerosis: correlations with lung involvement and inflammatory milieu. AB - AIM: Humoral immunity and B cells are thought to play an important role in the pathophysiology of the systemic sclerosis (SSc). The production of free light chains (FLC) of immunoglobulins is abnormally high in several pathological autoimmune conditions and reflects B cell activation. Furthermore, FLCs demonstrated different biological activities including their capability to modulate the immune system, proteolytic activity and complement cascade activation. The aims of this study are to determine the FLC levels in patients with SSc compared with healthy controls (HC) and to study their possible association with organ involvement and disease characteristics. METHODS: Sixty five patients with SSc and 20 HC were studied. Clinical and immunological inflammatory characteristics were assessed for all the patients with SSc. kappa FLC and lambda-FLC, interleukin 6 (IL-6) and B cell activating factor levels were measured. RESULTS: The mean serum kappa-FLC levels and FLC ratio were significantly higher in patients with SSc compared with HC, while the serum lambda-FLC levels were comparable.The levels of FLC were comparable in patients with diffuse skin disease and limited skin involvement, while kappa-FLC levels were increased in patients with restrictive lung (forced vital capacity (FVC) <80%) disease (26.4+/-7.4 mg/L) when compared with patients with FVC >=80% (19.6+/-7.3 mg/L, P=0.009). In patients with SSc, the levels of serum kappa-FLC level directly correlated with the IL-6 levels (R=0.3, P=0.001) and disease activity (R=0.4, P=0.003). CONCLUSIONS: FLC levels are elevated in SSc and high levels are associated with lung involvement and with a higher degree of inflammation, supporting a possible role of B cell activation in the pathophysiology of the disease. PMID- 29447114 TI - Higher D-lactate levels are associated with higher prevalence of small dense low density lipoprotein in obese adolescents. AB - BACKGROUND: Childhood obesity is associated with insulin resistance (IR), increased levels of small dense low-density lipoprotein (sd-LDL) as well as with augmented hepatic de novo lipogenesis, which implies increased triose phosphate fluxes that may lead to increased methylglyoxal (MG) and its catabolic end product D-lactate. We hypothesized that obese adolescents have increased D lactate serum levels associated with high incidence of sd-LDL. METHODS: This is a cross-sectional study where the anthropometric characteristics, atherogenic dyslipidemia complex, sd-LDL (Lipoprint, Quantimetrix) and D-lactate (kinetic enzymatic analysis) were explored in 30 lean vs. 30 obese adolescents (16 females and 14 males per group) without metabolic syndrome (MetS). Endothelial function by flow-mediated dilation (FMD, by ultrasound) and arterial lesion by carotid intima media thickness (CIMT, by ultrasound) were also measured. RESULTS: The mean age of participants was 16.8 +/- 1.4 years. Obese adolescents had a body mass index of 32.7 +/- 3.8 vs. 21.8 +/- 2.1 in lean participants. The obesity group showed higher D-lactate levels: 6.2 +/- 3.0 vs. 4.5 +/- 2.5 MUmol/L, higher levels of insulin: 15 (9.6-23.5) vs. 7.9 (6.5-10.5) MUIU/mL; triglyceride (TG): 1.46 (1.1-1.8) vs. 0.84 (0.6-1.2) mmol/L; non-high-density lipoprotein cholesterol (NON-HDL-C): 2.8 +/- 0.9 vs. 2.3 +/- 0.7 mmol/L; total cholesterol (TC)/HDL-C) index: 2.9 +/- 0.7 vs. 2.4 +/- 0.5; TG/HDL-C index: 2.2 (1.5-2.8) vs. 1.1 (0.8-1.8); %LDL-3: 4.2 +/- 4.07 vs. 1.9 +/- 2.7; smaller LDL size: 270.6 +/- 3 vs. 272.2 +/- 1.1 A. D-lactate correlated positively with LDL-2: r = 0.44 and LDL-3 (sd-LDL): r = 0.49 and negatively with large LDL-1: r = -0.48 and LDL size: r = -0.46; (p<0.05, p<0.01, p<0.001 and p<0.0001, respectively). Obese adolescents showed higher CIMT: 0.51 +/- 0.08 vs. 0.46 +/- 0.08 mm and lower FMD: 20.3% +/- 6.7% vs. 26.0% +/- 9.3%. CONCLUSIONS: Obese adolescents display subclinical signs of IR and endothelial dysfunction. Higher serum sd-LDL levels correlated positively with D-lactate levels. These findings suggest an association between atherogenic dyslipoproteinemia and whole body MG fluxes already detectable in apparently healthy obese adolescents.

AB - A major feature of Alzheimer's disease (AD) pathology is the plaque composed of aggregated amyloid-beta (Abeta) peptide. Although these plaques may have harmful properties, there is much evidence to implicate soluble oligomeric Abeta as the primary noxious form. Abeta oligomers can be generated both extracellularly and intracellularly. Abeta is toxic to neurons in a myriad of ways. It can cause pore formation resulting in the leakage of ions, disruption of cellular calcium balance, and loss of membrane potential. It can promote apoptosis, cause synaptic loss, and disrupt the cytoskeleton. Current treatments for AD are limited and palliative. Much research and effort is being devoted to reducing Abeta production as an approach to slowing or preventing the development of AD. Abeta formation results from the amyloidogenic cleavage of human amyloid precursor protein (APP). Reconfiguring this process to disfavor amyloid generation might be possible through the reduction of APP or inhibition of enzymes that convert the precursor protein to amyloid. PMID- 29447117 TI - On the high-lift characteristics of a bio-inspired, slotted delta wing. AB - A bio-inspired, slotted delta wing was abstracted from a multi-vane propulsor geometry ubiquitous in nature, and analysed to investigate aerodynamic performance during acceleratory and steady-state motions. Evolutionary convergence of slotted geometries in nature suggests an aerodynamic benefit in manoeuvrability, as exemplified in the fins and wings of a broad range of extant and extinct swimmers and flyers, respectively. Through direct force measurements and stereoscopic particle image velocimetry, it was found that the abstracted, slotted geometry exhibited a region of steady-state lift and drag enhancement at angles of attack greater than 25 degrees when compared to a reference profile based on a delta-wing plate. At an angle of attack of 30 degrees , the lift and drag measured on the abstracted model were 15.3% and 17.0% higher than the delta wing model, respectively. In contrast, these shapes showed little difference in performance during an acceleration-from-rest manoeuvre. It was found that the secondary and tertiary vanes of the abstraction encouraged the formation of additional leading-edge vorticity. The formation of these additional leading-edge vortices was confirmed by an increase in streamwise circulation measured near each effective leading edge along the length of the chord. As such, this configuration provides lift augmentation appropriate for the development of high performance control surfaces. PMID- 29447118 TI - Fluorescence properties of Yb3+-Er3+ co-doped phosphate glasses containing silver nanoparticles. AB - Er3+-Yb3+ co-doped phosphate glasses containing silver nitrate (SN), were fabricated. Transmission electron microscopy (TEM) and x-ray photoelectron spectroscopy (XPS) analyses were used to evidence the nucleation and presence of silver nanoparticles (SNP). The basic parameters of the glasses were inspected by means of absorption and fluorescence spectra, and fluorescence lifetimes under excitation at 916 nm (in-band of Yb3+), and at 406 nm (in-band of surface plasmon resonance given by the presence of SNP). The spectra as well as estimates for the basic parameters defining the lasing/amplifying potential of the glasses were studied as a function of SN concentration. The experimental results indicate that by increasing the SN content an enhancement of Er3+/Yb3+ fluorescence takes place.

AB - In a scenario of accidental mass radiation exposure transportation and analysis of samples may take some time, resulting in loss of biomarker information over this period. The present study aims to use phosphatase inhibitors for longer retention of focal signals to adopt gamma-H2AX as a biodosimetric biomarker for the management of early triage. Peripheral blood lymphocytes isolated from healthy individuals were irradiated in vitro with x-rays and gamma-H2AX foci were analysed using fluorescent microscopy and flow cytometric methods. Further, the effect of protein phosphatase 2A inhibitors such as calyculin A, fostriecin and okadiac acid on the retention of foci was studied. Fluorescent microscopy was found to be a more sensitive method than flow cytometry. Calyculin A showed significant retention of focal signals at 6 h with 1.5-fold increased retention compared to radiation alone; this may prove beneficial in early triage management because of a better dose approximation. PMID- 29447120 TI - Quasiparticle scattering in type-II Weyl semimetal MoTe2. AB - The electronic structure of type-II Weyl semimetal molybdenum ditelluride (MoTe2) is studied by using scanning tunneling microscopy and density functional theory calculations. Through measuring energy-dependent quasiparticle interference (QPI) patterns with a cryogenic scanning tunneling microscope, several characteristic features are found in the QPI patterns. Two of them arise from the Weyl semimetal nature; one is the topological Fermi arc surface state and the other can be assigned to be a Weyl point. The remaining structures are derived from the scatterings relevant to the bulk electronic states. The findings lead to further understanding of the topological electronic structure of type-II Weyl semimetal MoTe2. PMID- 29447121 TI - P3HT-graphene bilayer electrode for Schottky junction photodetectors. AB - We have investigated the effect of a poly (3-hexylthiophene-2.5-diyl)(P3HT) graphene bilayer electrode on the photoresponsivity characteristics of Si-based Schottky photodetectors. P3HT, which is known to be an electron donor and absorb light in the visible spectrum, was placed on CVD grown graphene by dip-coating method. The results of the UV-vis and Raman spectroscopy measurements have been evaluated to confirm the optical and electronic modification of graphene by the P3HT thin film. Current-voltage measurements of graphene/Si and P3HT-graphene/Si revealed rectification behavior confirming a Schottky junction formation at the graphene/Si interface. Time-resolved photocurrent spectroscopy measurements showed the devices had excellent durability and a fast response speed. We found that the maximum spectral photoresponsivity of the P3HT-graphene/Si photodetector increased more than three orders of magnitude compared to that of the bare graphene/Si photodetector. The observed increment in the photoresponsivity of the P3HT-graphene/Si samples was attributed to the charge transfer doping from P3HT to graphene within the spectral range between near-ultraviolet and near-infrared. Furthermore, the P3HT-graphene electrode was found to improve the specific detectivity and noise equivalent power of graphene/Si photodetectors. The obtained results showed that the P3HT-graphene bilayer electrodes significantly improved the photoresponsivity characteristics of our samples and thus can be used as a functional component in Si-based optoelectronic device applications. PMID- 29447122 TI - 18F-FDG production procedures as a source of eye lens exposure to radiation. AB - Decreasing the individual dose limit of exposure to ionizing radiation to the eye lenses means verifying the need for routine monitoring of the eye lenses of workers exposed to ionizing radiation, including those employed in facilities producing radiopharmaceuticals based on short-lived isotopes. This work analyzes the exposure of the eye lenses of employees of centers that produce the isotopes for positron emission tomography, in particular fluorine-18. It takes into account the employment structure and work system of the discussed centers, including in terms of changing the dose limit of exposure to the eye lenses. This work complements the paper by Wrzesien (2018 Australas. Phys. Eng. Sci. Med. submitted) , which focused on the exposure of workers' hands to ionizing radiation in radiopharmaceutical production centers. Measurements were carried out using high-sensitivity thermoluminescence detectors (LiF: Mg, Cu, P-MCP-N). The measurements covered 17 employees. Our results show that the highest values of personal dose equivalent Hp(3) were recorded for the 18F-FDG quality control personnel and nurses who injected the radiopharmaceutical in the patients. In the group of nurses, the maximum daily does Hp(3) reached a value close to 200 MUSv. For staff who performed the quality control of the 18F-FDG, the maximum daily dose of Hp(3) exceeded 200 MUSv. The estimated annual exposure of the eye lenses of workers in these two occupational groups may exceed the new dose limit (20 mSv/year). Results of this study indicate the need for optimization of the procedures related to quality control of radiopharmaceuticals and the injection of 18F-FDG in patients. PMID- 29447123 TI - Fast and controlled fabrication of porous graphene oxide: application of AFM tapping for mechano-chemistry. AB - This paper describes a novel method to fabricate porous graphene oxide (PGO) from GO by exposure to oxygen plasma. Compared to other methods to fabricate PGO described so far, e.g. the thermal and steam etching methods, oxygen plasma etching method is much faster. We studied the development of the porosity with exposure time using atomic force microscopy (AFM). It was found that the development of PGO upon oxygen-plasma exposure can be controlled by tapping mode AFM scanning using a Si tip. AFM tapping stalls the growth of pores upon further plasma exposure at a level that coincides with the fraction of sp2 carbons in the GO starting material. We suggest that AFM tapping procedure changes the bond structure of the intermediate PGO structure, and these stabilized PGO structures cannot be further etched by oxygen plasma. This constitutes the first report of tapping AFM as a tool for local mechano-chemistry. PMID- 29447124 TI - Spin crossover and high spin filtering behavior in Co-Pyridine and Co-Pyrimidine molecules. AB - We present a theoretical study on a series of cobalt complexes, which are constructed with cobalt atoms and pyridine/pyrimidine rings, using density functional theory. We investigate the structural and electric transport properties of spin crossover (SCO) Co complex with two spin states, namely low spin configuration [LS] and high-spin configuration [HS]. Energy analyses of the two spin states imply that the SCO Co-Pyridine2 and Co-Pyrimidine2 complexes may display a spin transition process accompanied by a geometric modification driven by external stimuli. A nearly perfect spin filtering effect is observed in the Co Pyrimidine2 complex with [HS] state. In addition, we also discover the contact dependent transmission properties of Co-Pyridine2. These findings indicate that SCO Co complexes are promising materials for molecular spintronic devices. PMID- 29447125 TI - The digital revolution.

PMID- 29447133 TI - Computerised training improves cognitive performance in chronic pain: a participant-blinded randomised active-controlled trial with remote supervision. AB - Chronic pain is associated with reduced efficiency of cognitive performance, and few studies have investigated methods of remediation. We trialled a computerised cognitive training protocol to determine whether it could attenuate cognitive difficulties in a chronic pain sample. Thirty-nine adults with chronic pain (mean age = 43.3, 61.5% females) were randomised to an 8-week online course (3 sessions/week from home) of game-like cognitive training exercises, or an active control involving watching documentary videos. Participants received weekly supervision by video call. Primary outcomes were a global neurocognitive composite (tests of attention, speed, and executive function) and self-reported cognition. Secondary outcomes were pain (intensity; interference), mood symptoms (depression; anxiety), and coping with pain (catastrophising; self-efficacy). Thirty participants (15 training and 15 control) completed the trial. Mixed model intention-to-treat analyses revealed significant effects of training on the global neurocognitive composite (net effect size [ES] = 0.43, P = 0.017), driven by improved executive function performance (attention switching and working memory). The control group reported improvement in pain intensity (net ES = 0.65, P = 0.022). Both groups reported subjective improvements in cognition (ES = 0.28, P = 0.033) and catastrophising (ES = 0.55, P = 0.006). Depression, anxiety, self efficacy, and pain interference showed no change in either group. This study provides preliminary evidence that supervised cognitive training may be a viable method for enhancing cognitive skills in persons with chronic pain, but transfer to functional and clinical outcomes remains to be demonstrated. Active control results suggest that activities perceived as relaxing or enjoyable contribute to improved perception of well-being. Weekly contact was pivotal to successful program completion. PMID- 29447131 TI - DNA repair deficiency sensitizes lung cancer cells to NAD+ biosynthesis blockade. AB - Synthetic lethality is an efficient mechanism-based approach to selectively target DNA repair defects. Excision repair cross-complementation group 1 (ERCC1) deficiency is frequently found in non-small-cell lung cancer (NSCLC), making this DNA repair protein an attractive target for exploiting synthetic lethal approaches in the disease. Using unbiased proteomic and metabolic high-throughput profiling on a unique in-house-generated isogenic model of ERCC1 deficiency, we found marked metabolic rewiring of ERCC1-deficient populations, including decreased levels of the metabolite NAD+ and reduced expression of the rate limiting NAD+ biosynthetic enzyme nicotinamide phosphoribosyltransferase (NAMPT). We also found reduced NAMPT expression in NSCLC samples with low levels of ERCC1. These metabolic alterations were a primary effect of ERCC1 deficiency, and caused selective exquisite sensitivity to small-molecule NAMPT inhibitors, both in vitro - ERCC1-deficient cells being approximately 1,000 times more sensitive than ERCC1 WT cells - and in vivo. Using transmission electronic microscopy and functional metabolic studies, we found that ERCC1-deficient cells harbor mitochondrial defects. We propose a model where NAD+ acts as a regulator of ERCC1-deficient NSCLC cell fitness. These findings open therapeutic opportunities that exploit a yet-undescribed nuclear-mitochondrial synthetic lethal relationship in NSCLC models, and highlight the potential for targeting DNA repair/metabolic crosstalks for cancer therapy. PMID- 29447132 TI - Role of GPCR (mu-opioid)-receptor tyrosine kinase (epidermal growth factor) crosstalk in opioid-induced hyperalgesic priming (type II). AB - Repeated stimulation of mu-opioid receptors (MORs), by an MOR-selective agonist DAMGO induces type II priming, a form of nociceptor neuroplasticity, which has 2 components: opioid-induced hyperalgesia (OIH) and prolongation of prostaglandin E2 (PGE2)-induced hyperalgesia. We report that intrathecal antisense knockdown of the MOR in nociceptors, prevented the induction of both components of type II priming. Type II priming was also eliminated by SSP-saporin, which destroys the peptidergic class of nociceptors. Because the epidermal growth factor receptor (EGFR) participates in MOR signaling, we tested its role in type II priming. The EGFR inhibitor, tyrphostin AG 1478, prevented the induction of prolonged PGE2 induced hyperalgesia, but not OIH, when tested out to 30 days after DAMGO. However, even when repeatedly injected, an EGFR agonist did not induce hyperalgesia or priming. A phosphopeptide, which blocks the interaction of Src, focal adhesion kinase (FAK), and EGFR, also prevented DAMGO-induced prolongation of PGE2 hyperalgesia, but only partially attenuated the induction of OIH. Inhibitors of Src and mitogen-activated protein kinase (MAPK) also only attenuated OIH. Inhibitors of matrix metalloproteinase, which cleaves EGF from membrane protein, markedly attenuated the expression, but did not prevent the induction, of prolongation of PGE2 hyperalgesia. Thus, although the induction of prolongation of PGE2-induced hyperalgesia at the peripheral terminal of peptidergic nociceptor is dependent on Src, FAK, EGFR, and MAPK signaling, Src, FAK, and MAPK signaling is only partially involved in the induction of OIH. PMID- 29447134 TI - Histone deacetylase 5 (HDAC5) regulates neuropathic pain through SRY-related HMG box 10 (SOX10)-dependent mechanism in mice. AB - A strong link between histone deacetylases (HDACs) and nociceptive hypersensitivity has been indicated in different pain models. However, the underlying molecular and cellular mechanisms remain elusive. Here, we discovered that partial sciatic nerve ligation-induced mechanical allodynia and thermal hyperalgesia in mice were associated with increased mRNA and protein expressions of HDAC5 (a member of class IIa HDACs) and SRY-related HMG-box 10 (SOX10) in the ipsilateral lumbar dorsal horn. Gene knockdown of spinal HDAC5 or SOX10 attenuated partial sciatic nerve ligation-induced nociceptive hypersensitivity, companied with decrease of spinal neuronal sensitization markers, namely phosphorylated-Erk, phosphorylated-GluN1 (ser896), and c-Fos. Conversely, overexpression of spinal HDAC5 or SOX10 by lentiviruses in naive mice not only induced pain-like behaviors but also increased the expression of these spinal neuronal sensitization markers. Of note, in contrast to its conventional deacetylation effect to silence gene expression, overexpression of HDAC5 not only enhanced SOX10 expression but also induced nociceptive hypersensitivity in naive mice, which were reversed by SOX10 gene knockdown. Chromatin-immunoprecipitation assay further confirmed a novel nonhistone modulation function of HDACs on SOX10 expression, that is, HDAC5 regulates SOX10 by binding to the promoter region of Sox10 gene. In conclusion, this study for the first time demonstrates that HDAC5 regulates spinal neuronal sensitization in neuropathic pain by upregulating modulating SOX10 expression. Thus, interventions that reduce HDAC5/SOX10 expression may represent promising avenues in the treatment of neuropathic pain. PMID- 29447135 TI - Introduction to the PAIN supplement on neuropathic pain. PMID- 29447136 TI - Individualized neuropathic pain therapy based on phenotyping: are we there yet? AB - Patients with the same neuropathic pain disorder may have completely different sensory signs and symptoms yet receive the same medicinal treatment. New concepts suggest that patient stratification according to their pain mechanisms, reflected in their sensory phenotype, could be promising to implement an individualized therapy in neuropathic pain. Retrospective classification of patients according to their sensory phenotype showed predictive validity and reliability for treatment response in certain subgroups of patients. Recent prospective studies using stratification based on sensory phenotypes confirm this concept. In this article, we review the recent accomplishments towards an individualized pharmacological treatment of neuropathic pain. PMID- 29447137 TI - Emerging therapies for neuropathic pain: new molecules or new indications for old treatments? AB - Neuropathic pain represents a highly unmet medical need because most of the available treatments have a modest efficacy or dose-limiting side effects. Hence, novel therapeutic perspectives are warranted. Many compounds acting on new pain targets are in preclinical or early clinical development. Only few clinical trials have suggested their clinical relevance in neuropathic pain. This concerns in particular NaV1.7 antagonists and angiotensin type II inhibitors. Another type of emerging drug therapy in neuropathic pain is represented by drugs largely used for other indications, such as botulinum toxin A and the antiepileptic oxcarbazepine, which have recently found to be effective in peripheral neuropathic pain. Emerging nondrug medical therapy with promising results in neuropathic pain also encompasses noninvasive brain neurostimulation techniques, such as repetitive transcranial magnetic stimulation and transcranial direct electrical stimulation. In this article, we review emerging medical treatments for neuropathic pain that are clinically available or with promising results from clinical trials. PMID- 29447138 TI - Inflammation in the pathophysiology of neuropathic pain. AB - Peripheral nerve injuries and diseases often lead to pain persisting beyond the resolution of damage, indicating an active disease-promoting process, which may result in chronic pain. This is regarded as a maladaptive mechanism resulting from neuroinflammation that originally serves to promote regeneration and healing. Knowledge on these physiological and pathophysiological processes has accumulated over the last few decades and has started to yield potential therapeutic targets. Key players are macrophages, T-lymphocytes, cytokines, and chemokines. In the spinal cord and brain, microglia and astrocytes are involved. Recently, data have been emerging on the regulation of these players. MicroRNAs and other noncoding RNAs have been discussed as potential master switches that may link nerve injury, pain, and inflammation. Clinical disorders most intensely studied in the context of neuroinflammation and pain are the complex regional pain syndrome, polyneuropathies, postherpetic neuralgia, and the fibromyalgia syndrome, in which recently a neuropathic component has been described. Research from several groups has shown an important role of both proinflammatory and anti inflammatory cytokines in neuropathic and other chronic pain states in humans. There is ample evidence of an analgesic action of anti-inflammatory cytokines in animal models. The interplay of anti-inflammatory cytokines and the nociceptive system provides possibilities and challenges concerning treatment strategies based on this concept. PMID- 29447139 TI - Global burden of neuropathic pain. AB - Global burden of disease studies measure the impact of disability and premature death resulting from specific diseases and injuries. Recently, these studies have highlighted the leading contribution of regional pain conditions (low back pain and neck pain in particular) to the global burden of disability. However, to date, there has not been a systematic approach to measuring the global burden of disease attributable to neuropathic pain (NP) conditions. This article gives a brief overview of the concept of burden of disease, the underlying drivers, and dynamics of disease burden at a population level and proposes an agenda in relation to NP for developing the conceptual and empirical evidence base necessary for estimating the global burden of NP. PMID- 29447140 TI - Resveratrol Improves Endothelial Progenitor Cell Function through miR-138 by Targeting Focal Adhesion Kinase (FAK) and Promotes Thrombus Resolution In Vivo. AB - BACKGROUND Endothelial progenitor cells (EPCs) were found to be a potential therapeutic choice for low extremity deep vein thrombosis. The aim of our research was to investigate the effect of resveratrol (RSV) on EPCs that may promote thrombus resolution and its potential pathway. MATERIAL AND METHODS EPCs were pretreated with RSV and migration; angiogenesis were evaluated ex vivo. Expression of miR-138 and focal adhesion kinase (FAK) was also tested. A murine model of venous thrombosis was developed as an in vivo model. The effects of RSV treatment on mice with inferior venous thrombosis were evaluated. RESULTS We found that RSV increased EPCs migration and tube formation ex vivo. RSV significantly inhibited miR-138 expression. Moreover, we demonstrated that FAK was a target of miR-138 and revealed that FAK knockdown downregulated migration and angiogenesis of RSV-treated EPCs. In addition, RSV-induced EPCs promoted thrombus resolution in a murine model of venous thrombosis. CONCLUSIONS We found the first evidence that intravenous injection of RSV-treated EPCs enhanced thrombus resolution in vivo. RSV exerted its role by reducing miR-138 expression and therefore upregulated FAK. PMID- 29447141 TI - Interim Estimates of 2017-18 Seasonal Influenza Vaccine Effectiveness - United States, February 2018. AB - In the United States, annual vaccination against seasonal influenza is recommended for all persons aged >=6 months (1). During each influenza season since 2004-05, CDC has estimated the effectiveness of seasonal influenza vaccine to prevent laboratory-confirmed influenza associated with medically attended acute respiratory illness (ARI). This report uses data from 4,562 children and adults enrolled in the U.S. Influenza Vaccine Effectiveness Network (U.S. Flu VE Network) during November 2, 2017-February 3, 2018. During this period, overall adjusted vaccine effectiveness (VE) against influenza A and influenza B virus infection associated with medically attended ARI was 36% (95% confidence interval [CI] = 27%-44%). Most (69%) influenza infections were caused by A(H3N2) viruses. VE was estimated to be 25% (CI = 13% to 36%) against illness caused by influenza A(H3N2) virus, 67% (CI = 54%-76%) against A(H1N1)pdm09 viruses, and 42% (CI = 25% 56%) against influenza B viruses. These early VE estimates underscore the need for ongoing influenza prevention and treatment measures. CDC continues to recommend influenza vaccination because the vaccine can still prevent some infections with currently circulating influenza viruses, which are expected to continue circulating for several weeks. Even with current vaccine effectiveness estimates, vaccination will still prevent influenza illness, including thousands of hospitalizations and deaths. Persons aged >=6 months who have not yet been vaccinated this season should be vaccinated. PMID- 29447142 TI - Prevalence of Obesity Among Youths by Household Income and Education Level of Head of Household - United States 2011-2014. AB - Obesity prevalence varies by income and education level, although patterns might differ among adults and youths (1-3). Previous analyses of national data showed that the prevalence of childhood obesity by income and education of household head varied across race/Hispanic origin groups (4). CDC analyzed 2011-2014 data from the National Health and Nutrition Examination Survey (NHANES) to obtain estimates of childhood obesity prevalence by household income (<=130%, >130% to <=350%, and >350% of the federal poverty level [FPL]) and head of household education level (high school graduate or less, some college, and college graduate). During 2011-2014 the prevalence of obesity among U.S. youths (persons aged 2-19 years) was 17.0%, and was lower in the highest income group (10.9%) than in the other groups (19.9% and 18.9%) and also lower in the highest education group (9.6%) than in the other groups (18.3% and 21.6%). Continued progress is needed to reduce disparities, a goal of Healthy People 2020. The overall Healthy People 2020 target for childhood obesity prevalence is <14.5% (5).

AB - During 2015-2016, the age-adjusted prevalence of HSV-1 was 48.1% among adolescents and adults aged 14-49 years (50.9% for females and 45.2% for males). Prevalence was higher for females than males in most 2-year periods from 1999 2000 to 2015-2016. Also during 2015-2016, the age-adjusted prevalence of HSV-2 for those aged 14-49 years was 12.1% (15.9% among females compared to 8.2% among males) and was higher for females than males for all 2-year periods. Prevalence significantly declined from 1999-2000 through 2015-2016 for HSV-1 and HSV-2 among both males and females.

PMID- 29447146 TI - Health-Risk Behaviors and Chronic Conditions Among Adults with Inflammatory Bowel Disease - United States, 2015 and 2016. AB - Inflammatory bowel disease (IBD), which includes Crohn's disease and ulcerative colitis, involves chronic inflammation of the gastrointestinal tract. In 2015, an estimated 3.1 million adults in the United States had ever received a diagnosis of IBD (1). Nationally representative samples of adults with IBD have been unavailable or too small to assess relationships between IBD and other chronic conditions and health-risk behaviors (2). To assess the prevalence of health-risk behaviors and chronic conditions among adults with and without IBD, CDC aggregated survey data from the 2015 and 2016 National Health Interview Survey (NHIS). An estimated 3.1 million (unadjusted lifetime prevalence = 1.3%) U.S. adults had ever received a diagnosis of IBD. Adults with IBD had a significantly lower prevalence of having never smoked cigarettes than did adults without the disease (55.9% versus 63.5%). Adults with IBD had significantly higher prevalences than did those without the disease in the following categories: having smoked and quit (26.0% versus 21.0%; having met neither aerobic nor muscle strengthening activity guidelines (50.4% versus 45.2%); reporting <7 hours of sleep, on average, during a 24-hour period (38.2% versus 32.2%); and having serious psychological distress (7.4% versus 3.4%). In addition, nearly all of the chronic conditions evaluated were more common among adults with IBD than among adults without IBD. Understanding the health-risk behaviors and prevalence of certain chronic conditions among adults with IBD could inform clinical practice and lead to better disease management. PMID- 29447148 TI - Reasons for Electronic Cigarette Use Among Middle and High School Students - National Youth Tobacco Survey, United States, 2016. AB - Electronic cigarettes (e-cigarettes) were the most commonly used tobacco product among U.S. middle school and high school students in 2016 (1). CDC and the Food and Drug Administration (FDA) analyzed data from the 2016 National Youth Tobacco Survey (NYTS) to assess self-reported reasons for e-cigarette use among U.S. middle school (grades 6-8) and high school (grades 9-12) student e-cigarette users. Among students who reported ever using e-cigarettes in 2016, the most commonly selected reasons for use were 1) use by "friend or family member" (39.0%); 2) availability of "flavors such as mint, candy, fruit, or chocolate" (31.0%); and 3) the belief that "they are less harmful than other forms of tobacco such as cigarettes" (17.1%). The least commonly selected reasons were 1) "they are easier to get than other tobacco products, such as cigarettes" (4.8%); 2) "they cost less than other tobacco products such as cigarettes" (3.2%); and 3) "famous people on TV or in movies use them" (1.5%). Availability of flavors as a reason for use was more commonly selected by high school users (32.3%) than by middle school users (26.8%). Efforts to prevent middle school and high school students from initiating the use of any tobacco product, including e-cigarettes, are important to reduce tobacco product use among U.S. youths (2). PMID- 29447147 TI - Assisted Reproductive Technology Surveillance - United States, 2015. AB - PROBLEM/CONDITION: Since the first U.S. infant conceived with assisted reproductive technology (ART) was born in 1981, both the use of ART and the number of fertility clinics providing ART services have increased steadily in the United States. ART includes fertility treatments in which eggs or embryos are handled in the laboratory (i.e., in vitro fertilization [IVF] and related procedures). Although the majority of infants conceived through ART are singletons, women who undergo ART procedures are more likely than women who conceive naturally to deliver multiple-birth infants. Multiple births pose substantial risks for both mothers and infants, including obstetric complications, preterm delivery (<37 weeks), and low birthweight (<2,500 g) infants. This report provides state-specific information for the United States (including the District of Columbia and Puerto Rico) on ART procedures performed in 2015 and compares birth outcomes that occurred in 2015 (resulting from ART procedures performed in 2014 and 2015) with outcomes for all infants born in the United States in 2015. PERIOD COVERED: 2015. DESCRIPTION OF SYSTEM: In 1995, CDC began collecting data on ART procedures performed in fertility clinics in the United States as mandated by the Fertility Clinic Success Rate and Certification Act of 1992 (FCSRCA) (Public Law 102-493 [October 24, 1992]). Data are collected through the National ART Surveillance System, a web-based data collection system developed by CDC. This report includes data from 52 reporting areas (the 50 states, the District of Columbia, and Puerto Rico). RESULTS: In 2015, a total of 182,111 ART procedures (range: 135 in Alaska to 23,198 in California) with the intent to transfer at least one embryo were performed in 464 U.S. fertility clinics and reported to CDC. These procedures resulted in 59,334 live-birth deliveries (range: 55 in Wyoming to 7,802 in California) and 71,152 infants born (range: 68 in Wyoming to 9,176 in California). Nationally, the number of ART procedures performed per 1 million women of reproductive age (15-44 years), a proxy measure of the ART utilization rate, was 2,832. ART use exceeded the national rate in 13 reporting areas (California, Connecticut, Delaware, the District of Columbia, Hawaii, Illinois, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Rhode Island, and Virginia). Nationally, among ART transfer procedures in patients using fresh embryos from their own eggs, the average number of embryos transferred increased with increasing age of the woman (1.6 among women aged <35 years, 1.8 among women aged 35-37 years, and 2.3 among women aged >37 years). Among women aged <35 years, the national elective single-embryo transfer (eSET) rate was 34.7% (range: 11.3% in Puerto Rico to 88.1% in Delaware). In 2015, ART contributed to 1.7% of all infants born in the United States (range: 0.3% in Puerto Rico to 4.5% in Massachusetts). ART also contributed to 17.0% of all multiple-birth infants, 16.8% of all twin infants, and 22.2% of all triplets and higher-order infants. The percentage of multiple birth infants was higher among infants conceived with ART (35.3%) than among all infants born in the total birth population (3.4%). Approximately 34.0% of ART conceived infants were twins and 1.0% were triplets and higher-order infants. Nationally, infants conceived with ART contributed to 5.1% of all low birthweight infants. Among ART-conceived infants, 25.5% had low birthweight, compared with 8.1% among all infants. ART-conceived infants contributed to 5.3% of all preterm (gestational age <37 weeks) infants. The percentage of preterm births was higher among infants conceived with ART (31.2%) than among all infants born in the total birth population (9.7%). Among singletons, the percentage of ART-conceived infants who had low birthweight was 8.7% compared with 6.4% among all infants born. The percentage of ART-conceived infants who were born preterm was 13.4% among singletons compared with 7.9% among all infants. INTERPRETATION: Multiple births from ART contributed to a substantial proportion of all twins, triplets, and higher-order infants born in the United States. For women aged <35 years, who are typically considered good candidates for eSET, the national average of 1.6 embryos was transferred per ART procedure. Of the four states (Illinois, Massachusetts, New Jersey, and Rhode Island) with comprehensive mandated health insurance coverage for ART procedures (i.e., coverage for at least four cycles of IVF), three (Illinois, Massachusetts, and New Jersey) had rates of ART use exceeding 1.5 times the national rate. This type of mandated insurance coverage has been associated with greater use of ART and likely accounts for some of the difference in per capita ART use observed among states. PUBLIC HEALTH ACTION: Twins account for the majority of ART-conceived multiple births. Reducing the number of embryos transferred and increasing use of eSET when clinically appropriate could help reduce multiple births and related adverse health consequences for both mothers and infants. State-based surveillance of ART might be useful for monitoring and evaluating maternal and infant health outcomes of ART in states with high ART use. PMID- 29447149 TI - Optimizing homeostatic cell renewal in hierarchical tissues. AB - In order to maintain homeostasis, mature cells removed from the top compartment of hierarchical tissues have to be replenished by means of differentiation and self-renewal events happening in the more primitive compartments. As each cell division is associated with a risk of mutation, cell division patterns have to be optimized, in order to minimize or delay the risk of malignancy generation. Here we study this optimization problem, focusing on the role of division tree length, that is, the number of layers of cells activated in response to the loss of terminally differentiated cells, which is related to the balance between differentiation and self-renewal events in the compartments. Using both analytical methods and stochastic simulations in a metapopulation-style model, we find that shorter division trees are advantageous if the objective is to minimize the total number of one-hit mutants in the cell population. Longer division trees on the other hand minimize the accumulation of two-hit mutants, which is a more likely evolutionary goal given the key role played by tumor suppressor genes in cancer initiation. While division tree length is the most important property determining mutant accumulation, we also find that increasing the size of primitive compartments helps to delay two-hit mutant generation.

AB - Viral infections are one of the major causes of death worldwide, with HIV infection alone resulting in over 1.2 million casualties per year. Antiviral drugs are now being administered for a variety of viral infections, including HIV, hepatitis B and C, and influenza. These therapies target a specific phase of the virus's life cycle, yet their ultimate success depends on a variety of factors, such as adherence to a prescribed regimen and the emergence of viral drug resistance. The epidemiology and evolution of drug resistance have been extensively characterized, and it is generally assumed that drug resistance arises from mutations that alter the virus's susceptibility to the direct action of the drug. In this paper, we consider the possibility that a virus population can evolve towards synchronizing its life cycle with the pattern of drug therapy. The periodicity of the drug treatment could then allow for a virus strain whose life cycle length is a multiple of the dosing interval to replicate only when the concentration of the drug is lowest. This process, referred to as "drug tolerance by synchronization", could allow the virus population to maximize its overall fitness without having to alter drug binding or complete its life cycle in the drug's presence. We use mathematical models and stochastic simulations to show that life cycle synchronization can indeed be a mechanism of viral drug tolerance. We show that this effect is more likely to occur when the variability in both viral life cycle and drug dose timing are low. More generally, we find that in the presence of periodic drug levels, time-averaged calculations of viral fitness do not accurately predict drug levels needed to eradicate infection, even if there is no synchronization. We derive an analytical expression for viral fitness that is sufficient to explain the drug-pattern-dependent survival of strains with any life cycle length. We discuss the implications of these findings for clinically relevant antiviral strategies.

AB - Cooperation and competition between human players in repeated microeconomic games offer a window onto social phenomena such as the establishment, breakdown and repair of trust. However, although a suitable starting point for the quantitative analysis of such games exists, namely the Interactive Partially Observable Markov Decision Process (I-POMDP), computational considerations and structural limitations have limited its application, and left unmodelled critical features of behavior in a canonical trust task. Here, we provide the first analysis of two central phenomena: a form of social risk-aversion exhibited by the player who is in control of the interaction in the game; and irritation or anger, potentially exhibited by both players. Irritation arises when partners apparently defect, and it potentially causes a precipitate breakdown in cooperation. Failing to model one's partner's propensity for it leads to substantial economic inefficiency. We illustrate these behaviours using evidence drawn from the play of large cohorts of healthy volunteers and patients. We show that for both cohorts, a particular subtype of player is largely responsible for the breakdown of trust, a finding which sheds new light on borderline personality disorder. PMID- 29447152 TI - A multiscale modelling approach to assess the impact of metabolic zonation and microperfusion on the hepatic carbohydrate metabolism. AB - The capacity of the liver to convert the metabolic input received from the incoming portal and arterial blood into the metabolic output of the outgoing venous blood has three major determinants: The intra-hepatic blood flow, the transport of metabolites between blood vessels (sinusoids) and hepatocytes and the metabolic capacity of hepatocytes. These determinants are not constant across the organ: Even in the normal organ, but much more pronounced in the fibrotic and cirrhotic liver, regional variability of the capillary blood pressure, tissue architecture and the expression level of metabolic enzymes (zonation) have been reported. Understanding how this variability may affect the regional metabolic capacity of the liver is important for the interpretation of functional liver tests and planning of pharmacological and surgical interventions. Here we present a mathematical model of the sinusoidal tissue unit (STU) that is composed of a single sinusoid surrounded by the space of Disse and a monolayer of hepatocytes. The total metabolic output of the liver (arterio-venous glucose difference) is obtained by integration across the metabolic output of a representative number of STUs. Application of the model to the hepatic glucose metabolism provided the following insights: (i) At portal glucose concentrations between 6-8 mM, an intra sinusoidal glucose cycle may occur which is constituted by glucose producing periportal hepatocytes and glucose consuming pericentral hepatocytes, (ii) Regional variability of hepatic blood flow is higher than the corresponding regional variability of the metabolic output, (iii) a spatially resolved metabolic functiogram of the liver is constructed. Variations of tissue parameters are equally important as variations of enzyme activities for the control of the arterio-venous glucose difference. PMID- 29447154 TI - Examining the controllability of sepsis using genetic algorithms on an agent based model of systemic inflammation. AB - Sepsis, a manifestation of the body's inflammatory response to injury and infection, has a mortality rate of between 28%-50% and affects approximately 1 million patients annually in the United States. Currently, there are no therapies targeting the cellular/molecular processes driving sepsis that have demonstrated the ability to control this disease process in the clinical setting. We propose that this is in great part due to the considerable heterogeneity of the clinical trajectories that constitute clinical "sepsis," and that determining how this system can be controlled back into a state of health requires the application of concepts drawn from the field of dynamical systems. In this work, we consider the human immune system to be a random dynamical system, and investigate its potential controllability using an agent-based model of the innate immune response (the Innate Immune Response ABM or IIRABM) as a surrogate, proxy system. Simulation experiments with the IIRABM provide an explanation as to why single/limited cytokine perturbations at a single, or small number of, time points is unlikely to significantly improve the mortality rate of sepsis. We then use genetic algorithms (GA) to explore and characterize multi-targeted control strategies for the random dynamical immune system that guide it from a persistent, non-recovering inflammatory state (functionally equivalent to the clinical states of systemic inflammatory response syndrome (SIRS) or sepsis) to a state of health. We train the GA on a single parameter set with multiple stochastic replicates, and show that while the calculated results show good generalizability, more advanced strategies are needed to achieve the goal of adaptive personalized medicine. This work evaluating the extent of interventions needed to control a simplified surrogate model of sepsis provides insight into the scope of the clinical challenge, and can serve as a guide on the path towards true "precision control" of sepsis.

AB - Trachoma is the leading infectious cause of blindness in the world and is associated with precarious living conditions in developing countries. The aim of the present study was to evaluate the prevalence of trachoma in three municipalities of the Marajo Archipelago, located in the state of Para, Brazil. In 2008, 2,054 schoolchildren from the public primary school system of the urban area of the region and their communicants were clinically examined; in 2016, 1,502 schoolchildren were examined. The positive cases seen during the clinical evaluation were confirmed by direct immunofluorescence (DIF) laboratory tests. The presence of antibodies against the genus Chlamydia was evaluated by indirect immunofluorescence (IIF), and the serotypes were determined by microimmunofluorescence (MIF). In 2008, the prevalence of trachoma among schoolchildren was 3.4% (69 cases) and it was more frequent in children between six and nine years of age and in females; among the communicants, a prevalence of 16.5% was observed. In 2016, three cases of trachoma were diagnosed (prevalence of 0.2%), found only in the municipality of Soure. The results of the present study showed that in 2008, trachoma had a low prevalence (3.4%) among schoolchildren in the urban area of Marajo Archipelago; eight years after the first evaluation and the introduction of control and prevention measures (SAFE strategy), there was a drastic reduction in the number of cases (0.2%), demonstrating the need for constant monitoring and effective measures for the elimination of trachoma. PMID- 29447157 TI - An inconclusive study comparing the effect of concrete and abstract descriptions of belief-inconsistent information. AB - Linguistic bias is the differential use of linguistic abstraction (as defined by the Linguistic Category Model) to describe the same behaviour for members of different groups. Essentially, it is the tendency to use concrete language for belief-inconsistent behaviours and abstract language for belief-consistent behaviours. Having found that linguistic bias is produced without intention or awareness in many contexts, researchers argue that linguistic bias reflects, reinforces, and transmits pre-existing beliefs, thus playing a role in belief maintenance. Based on the Linguistic Category Model, this assumes that concrete descriptions reduce the impact of belief-inconsistent behaviours while abstract descriptions maximize the impact of belief-consistent behaviours. However, a key study by Geschke, Sassenberg, Ruhrmann, and Sommer [2007] found that concrete descriptions of belief-inconsistent behaviours actually had a greater impact than abstract descriptions, a finding that does not fit easily within the linguistic bias paradigm. Abstract descriptions (e.g. the elderly woman is athletic) are, by definition, more open to interpretation than concrete descriptions (e.g. the elderly woman works out regularly). It is thus possible that abstract descriptions are (1) perceived as having less evidentiary strength than concrete descriptions, and (2) understood in context (i.e. athletic for an elderly woman). In this study, the design of Geschke et al. [2007] was modified to address this possibility. We expected that the differences in the impact of concrete and abstract descriptions would be reduced or reversed, but instead we found that differences were largely absent. This study did not support the findings of Geschke et al. [2007] or the linguistic bias paradigm. We encourage further attempts to understand the strong effect of concrete descriptions for belief inconsistent behaviour. PMID- 29447156 TI - West Nile and St. Louis encephalitis viral genetic determinants of avian host competence. AB - West Nile virus (WNV) and St. Louis encephalitis (SLEV) virus are enzootically maintained in North America in cycles involving the same mosquito vectors and similar avian hosts. However, these viruses exhibit dissimilar viremia and virulence phenotypes in birds: WNV is associated with high magnitude viremias that can result in mortality in certain species such as American crows (AMCRs, Corvus brachyrhynchos) whereas SLEV infection yields lower viremias that have not been associated with avian mortality. Cross-neutralization of these viruses in avian sera has been proposed to explain the reduced circulation of SLEV since the introduction of WNV in North America; however, in 2015, both viruses were the etiologic agents of concurrent human encephalitis outbreaks in Arizona, indicating the need to re-evaluate host factors and cross-neutralization responses as factors potentially affecting viral co-circulation. Reciprocal chimeric WNV and SLEV viruses were constructed by interchanging the pre-membrane (prM)-envelope (E) genes, and viruses subsequently generated were utilized herein for the inoculation of three different avian species: house sparrows (HOSPs; Passer domesticus), house finches (Haemorhous mexicanus) and AMCRs. Cross protective immunity between parental and chimeric viruses were also assessed in HOSPs. Results indicated that the prM-E genes did not modulate avian replication or virulence differences between WNV and SLEV in any of the three avian species. However, WNV-prME proteins did dictate cross-protective immunity between these antigenically heterologous viruses. Our data provides further evidence of the important role that the WNV / SLEV viral non-structural genetic elements play in viral replication, avian host competence and virulence. PMID- 29447158 TI - Interaction between nitric oxide and renal alpha1-adrenoreceptors mediated vasoconstriction in rats with left ventricular hypertrophyin Wistar Kyoto rats. AB - Left ventricular hypertrophy (LVH) is associated with decreased responsiveness of renal alpha1-adrenoreceptors subtypes to adrenergic agonists. Nitric oxide donors are known to have antihypertrophic effects however their impact on responsiveness of renal alpha1-adrenoreceptors subtypes is unknown. This study investigated the impact of nitric oxide (NO) and its potential interaction with the responsiveness of renal alpha1-adrenoreceptors subtypes to adrenergic stimulation in rats with left ventricular hypertrophy (LVH). This study also explored the impact of NO donor on CSE expression in normal and LVH kidney. LVH was induced using isoprenaline and caffeine in drinking water for 2 weeks while NO donor (L arginine, 1.25g/Lin drinking water) was given for 5 weeks. Intrarenal noradrenaline, phenylephrine and methoxamine responses were determined in the absence and presence of selective alpha1-adrenoceptor antagonists, 5- methylurapidil (5-MeU), chloroethylclonidine (CeC) and BMY 7378. Renal cortical endothelial nitric oxide synthase mRNA was upregulated 7 fold while that of cystathione gamma lyase was unaltered in the NO treated LVH rats (LVH-NO) group compared to LVH group. The responsiveness of renal alpha1A, alpha1B and alpha1D adrenoceptors in the low dose and high dose phases of 5-MeU, CEC and BMY7378 to adrenergic agonists was increased along with cGMP in the kidney of LVH-NO group. These findings suggest that exogenous NO precursor up-regulated the renal eNOS/NO/cGMP pathway in LVH rats and resulted in augmented alpha1A, alpha1B and alpha1D adrenoreceptors responsiveness to the adrenergic agonists. There is a positive interaction between H2S and NO production in normal animals but this interaction appears absent in LVH animals. PMID- 29447159 TI - A comprehensive and quantitative comparison of text-mining in 15 million full text articles versus their corresponding abstracts. AB - Across academia and industry, text mining has become a popular strategy for keeping up with the rapid growth of the scientific literature. Text mining of the scientific literature has mostly been carried out on collections of abstracts, due to their availability. Here we present an analysis of 15 million English scientific full-text articles published during the period 1823-2016. We describe the development in article length and publication sub-topics during these nearly 250 years. We showcase the potential of text mining by extracting published protein-protein, disease-gene, and protein subcellular associations using a named entity recognition system, and quantitatively report on their accuracy using gold standard benchmark data sets. We subsequently compare the findings to corresponding results obtained on 16.5 million abstracts included in MEDLINE and show that text mining of full-text articles consistently outperforms using abstracts only. PMID- 29447160 TI - Modeling the interactions of sense and antisense Period transcripts in the mammalian circadian clock network. AB - In recent years, it has become increasingly apparent that antisense transcription plays an important role in the regulation of gene expression. The circadian clock is no exception: an antisense transcript of the mammalian core-clock gene PERIOD2 (PER2), which we shall refer to as Per2AS RNA, oscillates with a circadian period and a nearly 12 h phase shift from the peak expression of Per2 mRNA. In this paper, we ask whether Per2AS plays a regulatory role in the mammalian circadian clock by studying in silico the potential effects of interactions between Per2 and Per2AS RNAs on circadian rhythms. Based on the antiphasic expression pattern, we consider two hypotheses about how Per2 and Per2AS mutually interfere with each other's expression. In our pre-transcriptional model, the transcription of Per2AS RNA from the non-coding strand represses the transcription of Per2 mRNA from the coding strand and vice versa. In our post-transcriptional model, Per2 and Per2AS transcripts form a double-stranded RNA duplex, which is rapidly degraded. To study these two possible mechanisms, we have added terms describing our alternative hypotheses to a published mathematical model of the molecular regulatory network of the mammalian circadian clock. Our pre-transcriptional model predicts that transcriptional interference between Per2 and Per2AS can generate alternative modes of circadian oscillations, which we characterize in terms of the amplitude and phase of oscillation of core clock genes. In our post transcriptional model, Per2/Per2AS duplex formation dampens the circadian rhythm. In a model that combines pre- and post-transcriptional controls, the period, amplitude and phase of circadian proteins exhibit non-monotonic dependencies on the rate of expression of Per2AS. All three models provide potential explanations of the observed antiphasic, circadian oscillations of Per2 and Per2AS RNAs. They make discordant predictions that can be tested experimentally in order to distinguish among these alternative hypotheses. PMID- 29447161 TI - Mycobacterium tuberculosis complex genotypes circulating in Nigeria based on spoligotyping obtained from Ziehl-Neelsen stained slides extracted DNA. AB - METHODS: All State TB control programmes in Nigeria were requested to submit 25 50 smear-positive Ziehl-Neelsen (ZN) stained slides for screening during 2013 2014. DNA was extracted from 929 slides for spoligotyping and drug-resistance analysis using microbead-based flow-cytometry suspension arrays. RESULTS: Spoligotyping results were obtained for 549 (59.1%) of 929 samples. Lineage 4 Cameroon sublineage (L4.6.2) represented half of the patterns, Mycobacterium africanum (L5 and L6) represented one fifth of the patterns, and all other lineages, including other L4 sublineages, represented one third of the patterns. Sublineage L4.6.2 was mostly identified in the north of the country whereas L5 was mostly observed in the south and L6 was scattered. The spatial distribution of genotypes had genetic geographic gradients. We did not obtain results enabling the detection of drug-resistance mutations. CONCLUSION/SIGNIFICANCE: We present the first national snapshot of the M. tuberculosis spoligotypes circulating in Nigeria based on ZN slides. Spoligotyping data can be obtained in a rapid and high-throughput manner with DNA extracted from ZN-stained slides, which may potentially improve our understanding of the genetic epidemiology of TB. PMID- 29447162 TI - Early experiences mediate distinct adult gene expression and reproductive programs in Caenorhabditis elegans. AB - Environmental stress during early development in animals can have profound effects on adult phenotypes via programmed changes in gene expression. Using the nematode C. elegans, we demonstrated previously that adults retain a cellular memory of their developmental experience that is manifested by differences in gene expression and life history traits; however, the sophistication of this system in response to different environmental stresses, and how it dictates phenotypic plasticity in adults that contribute to increased fitness in response to distinct environmental challenges, was unknown. Using transcriptional profiling, we show here that C. elegans adults indeed retain distinct cellular memories of different environmental conditions. We identified approximately 500 genes in adults that entered dauer due to starvation that exhibit significant opposite ("seesaw") transcriptional phenotypes compared to adults that entered dauer due to crowding, and are distinct from animals that bypassed dauer. Moreover, we show that two-thirds of the genes in the genome experience a 2-fold or greater seesaw trend in gene expression, and based upon the direction of change, are enriched in large, tightly linked regions on different chromosomes. Importantly, these transcriptional programs correspond to significant changes in brood size depending on the experienced stress. In addition, we demonstrate that while the observed seesaw gene expression changes occur in both somatic and germline tissue, only starvation-induced changes require a functional GLP-4 protein necessary for germline development, and both programs require the Argonaute CSR-1. Thus, our results suggest that signaling between the soma and the germ line can generate phenotypic plasticity as a result of early environmental experience, and likely contribute to increased fitness in adverse conditions and the evolution of the C. elegans genome.

PMID- 29447163 TI - Paternal lineage early onset hereditary ovarian cancers: A Familial Ovarian Cancer Registry study. AB - Given prior evidence that an affected woman conveys a higher risk of ovarian cancer to her sister than to her mother, we hypothesized that there exists an X linked variant evidenced by transmission to a woman from her paternal grandmother via her father. We ascertained 3,499 grandmother/granddaughter pairs from the Familial Ovarian Cancer Registry at the Roswell Park Cancer Institute observing 892 informative pairs with 157 affected granddaughters. We performed germline X chromosome exome sequencing on 186 women with ovarian cancer from the registry. The rate of cancers was 28.4% in paternal grandmother/granddaughter pairs and 13.9% in maternal pairs consistent with an X-linked dominant model (Chi-square test X2 = 0.02, p = 0.89) and inconsistent with an autosomal dominant model (X2 = 20.4, p<0.001). Paternal grandmother cases had an earlier age-of-onset versus maternal cases (hazard ratio HR = 1.59, 95%CI: 1.12-2.25) independent of BRCA1/2 status. Reinforcing the X-linked hypothesis, we observed an association between prostate cancer in men and ovarian cancer in his mother and daughters (odds ratio, OR = 2.34, p = 0.034). Unaffected mothers with affected daughters produced significantly more daughters than sons (ratio = 1.96, p<0.005). We performed exome sequencing in reported BRCA negative cases from the registry. Considering age-of-onset, one missense variant (rs176026 in MAGEC3) reached chromosome-wide significance (Hazard ratio HR = 2.85, 95%CI: 1.75-4.65) advancing the age of onset by 6.7 years. In addition to the well-known contribution of BRCA, we demonstrate that a genetic locus on the X-chromosome contributes to ovarian cancer risk. An X-linked pattern of inheritance has implications for genetic risk stratification. Women with an affected paternal grandmother and sisters of affected women are at increased risk for ovarian cancer. Further work is required to validate this variant and to characterize carrier families. PMID- 29447165 TI - Comparison of three data mining models for prediction of advanced schistosomiasis prognosis in the Hubei province. AB - BACKGROUND: In order to better assist medical professionals, this study aimed to develop and compare the performance of three models-a multivariate logistic regression (LR) model, an artificial neural network (ANN) model, and a decision tree (DT) model-to predict the prognosis of patients with advanced schistosomiasis residing in the Hubei province. METHODOLOGY/PRINCIPAL FINDINGS: Schistosomiasis surveillance data were collected from a previous study based on a Hubei population sample including 4136 advanced schistosomiasis cases. The predictive models use LR, ANN, and DT methods. From each of the three groups, 70% of the cases (2896 cases) were used as training data for the predictive models. The remaining 30% of the cases (1240 cases) were used as validation groups for performance comparisons between the three models. Prediction performance was evaluated using area under the receiver operating characteristic curve (AUC), sensitivity, specificity, and accuracy. Univariate analysis indicated that 16 risk factors were significantly associated with a patient's outcome of prognosis. In the training group, the mean AUC was 0.8276 for LR, 0.9267 for ANN, and 0.8229 for DT. In the validation group, the mean AUC was 0.8349 for LR, 0.8318 for ANN, and 0.8148 for DT. The three models yielded similar results in terms of accuracy, sensitivity, and specificity. CONCLUSIONS/SIGNIFICANCE: Predictive models for advanced schistosomiasis prognosis, respectively using LR, ANN and DT models were proved to be effective approaches based on our dataset. The ANN model outperformed the LR and DT models in terms of AUC. PMID- 29447166 TI - A molecular basis behind heterophylly in an amphibious plant, Ranunculus trichophyllus. AB - Ranunculus trichophyllus is an amphibious plant that produces thin and cylindrical leaves if grown under water but thick and broad leaves if grown on land. We found that such heterophylly is widely controlled by two plant hormones, abscisic acid (ABA) and ethylene, which control terrestrial and aquatic leaf development respectively. Aquatic leaves produced higher levels of ethylene but lower levels of ABA than terrestrial leaves. In aquatic leaves, their distinct traits with narrow shape, lack of stomata, and reduced vessel development were caused by EIN3-mediated overactivation of abaxial genes, RtKANADIs, and accompanying with reductions of STOMAGEN and VASCULAR-RELATED NAC-DOMAIN7 (VDN7). In contrast, in terrestrial leaves, ABI3-mediated activation of the adaxial genes, RtHD-ZIPIIIs, and STOMAGEN and VDN7 established leaf polarity, and stomata and vessel developments. Heterophylly of R.trichophyllus could be also induced by external cues such as cold and hypoxia, which is accompanied with the changes in the expression of leaf polarity genes similar to aquatic response. A closely related land plant R. sceleratus did not show such heterophyllic responses, suggesting that the changes in the ABA/ethylene signaling and leaf polarity are one of key evolutionary steps for aquatic adaptation. PMID- 29447167 TI - Activating attachments enhances heart rate variability. AB - Although activating mental representations of attachment figures is beneficial for psychological health, there is a paucity of knowledge of the underlying mechanisms. We investigated how priming attachment figures may modulate parasympathetic stress response. Participants (N = 62) with varying degrees of attachment security underwent a cold pressor test, and then imagined an attachment or non-attachment figure. Heart rate variability was assessed throughout the study. Participants with low avoidant attachment levels displayed less negative affect and greater heart rate variability following the attachment prime than those who imagined the non-attachment prime. This beneficial effect of attachment priming was not observed in participants with high avoidant attachment levels. These findings highlight that activating attachment representations can enhance the parasympathetic stress response in people with secure attachment styles, and provides one explanation for the psychological benefits of attachment proximity. PMID- 29447168 TI - Quantitative proteome profile of water deficit stress responses in eastern cottonwood (Populus deltoides) leaves. AB - Drought stress is a recurring feature of world climate and the single most important factor influencing agricultural yield worldwide. Plants display highly variable, species-specific responses to drought and these responses are multifaceted, requiring physiological and morphological changes influenced by genetic and molecular mechanisms. Moreover, the reproducibility of water deficit studies is very cumbersome, which significantly impedes research on drought tolerance, because how a plant responds is highly influenced by the timing, duration, and intensity of the water deficit. Despite progress in the identification of drought-related mechanisms in many plants, the molecular basis of drought resistance remains to be fully understood in trees, particularly in poplar species because their wide geographic distribution results in varying tolerances to drought. Herein, we aimed to better understand this complex phenomenon in eastern cottonwood (Populus deltoides) by performing a detailed contrast of the proteome changes between two different water deficit experiments to identify functional intersections and divergences in proteome responses. We investigated plants subjected to cyclic water deficit and compared these responses to plants subjected to prolonged acute water deficit. In total, we identified 108,012 peptide sequences across both experiments that provided insight into the quantitative state of 22,737 Populus gene models and 8,199 functional protein groups in response to drought. Together, these datasets provide the most comprehensive insight into proteome drought responses in poplar to date and a direct proteome comparison between short period dehydration shock and cyclic, post-drought re-watering. Overall, this investigation provides novel insights into drought avoidance mechanisms that are distinct from progressive drought stress. Additionally, we identified proteins that have been associated as drought-relevant in previous studies. Importantly, we highlight the RD26 transcription factor as a gene regulated at both the transcript and protein level, regardless of species and drought condition, and, thus, represents a key, universal drought marker for Populus species. PMID- 29447169 TI - Occurrence of measles in a country with elimination status: Amplifying measles infection in hospitalized children due to imported virus. AB - The Republic of Korea declared measles elimination in 2006. However, a measles outbreak occurred in 2013. This study aimed to identify the epidemiological characteristics of the sources of infection and the pattern of measles transmission in 2013 in South Korea. We utilized surveillance data, epidemiological data, immunization registry data, and genetic information. We describe the epidemiological characteristics of all measles case patients (sex, age distribution, vaccination status, sources of infection) as well as details of the outbreak (the pattern of transmission, duration, mean age of patients, and generation time). In 2013, a total of 107 measles cases were notified. Most patients were infants (43.0%) and unvaccinated individuals (60.7%). We identified 4 imported and 103 import-related cases. A total of 105 cases were related to four outbreaks that occurred in Gyeongnam, northern Gyeonggi, southern Gyeonggi, and Seoul. The predominant circulating genotype was B3 type, which was identified in the Gyeongnam, northern Gyeonggi, and southern Gyeonggi outbreaks. The B3 type had not been in circulation in South Korea in the previous 3 years; virologic evidence suggests that these outbreaks were import-related. Most measles cases in South Korea have been associated with imported measles virus. Although Korea has maintained a high level of herd immunity, clustering of susceptible people can cause such measles outbreaks. PMID- 29447170 TI - Imported endemic mycoses in Spain: Evolution of hospitalized cases, clinical characteristics and correlation with migratory movements, 1997-2014. AB - Endemic mycoses are systemic fungal infections. Histoplasmosis is endemic in all temperate areas of the world; coccidioidomycosis and paracoccidioidomycosis are only present in the American continent. These pathogens are not present in Spain, but in the last years there has been an increase of reported cases due to migration and temporary movements. We obtained from the Spanish hospitals records clinical and demographic data of all hospitalized cases between 1997 and 2014. There were 286 cases of histoplasmosis, 94 of Coccidioidomycosis and 25 of paracoccidioidomycosis. Overall, histoplasmosis was strongly related to HIV infection, as well as with greater morbidity and mortality. For the other mycoses, we did not find any immunosuppressive condition in most of the cases. Although we were not able to obtain data about clinical presentation of all the cases, the most frequently found was pulmonary involvement. We also found a temporal correlation between the Spanish population born in endemic countries and the number of hospitalized cases along this period. This study reflects the importance of imported diseases in non-endemic countries due to migratory movements.

AB - INTRODUCTION: Refractive error is an important cause of correctable visual impairment in the worldwide with a global distribution of 1.75% to 20.7% among schoolchildren. Teacher's knowledge about refractive error play an important role in encouraging students to seek treatment that helps in reducing the burden of visual impairment. OBJECTIVE: To determine knowledge, attitude and associated factors among primary school teachers regarding refractive error in school children in Gondar city. METHODS: Institution based cross-sectional study was conducted on 565 primary school teachers in Gondar city using pretested and structured self-administered questionnaire. For processing and analysis, SPSS version 20 was used and variables which had a P value of <0.05 in the multivariable analysis were considered as statistically significant. RESULT: A total of 565 study subjects were participated in this study with a mean age of 42.05 +/- 12.01 years. Of these study participants 55.9% (95% CI: 51.9, 59.8) had good knowledge and 57.2% (95% CI: 52.9, 61.4) had favorable attitude towards refractive error. History of spectacle use [AOR = 2.13 (95% CI: 1.32, 3.43)], history of eye examination [AOR = 1.67 (95% CI: 1.19, 2.34)], training on eye health [AOR = 1.94 (95% CI; 1.09, 3.43)] and 11-20 years of experience [AOR = 2.53 (95% CI: 1.18, 5.43)] were positively associated with knowledge. Whereas being male [AOR = 2.03 (95% CI: 1.37, 3.01)], older age [AOR = 3.05 (95% CI: 1.07, 8.72)], 31-40 years of experience [AOR = 0.23 (95% CI: 0.07, 0.72)], private school type [AOR = 1.76 (95% CI: 1.06, 2.93)] and 5th -8th teaching category [AOR = 1.54 (95% CI: 1.05, 2.24)] were associated with attitude. CONCLUSION: Knowledge and attitude of study subjects were low which needs training of teachers about the refractive error.

AB - The cohesin complex topologically encircles chromosomes and mediates sister chromatid cohesion to ensure accurate chromosome segregation upon cell division. Cohesin also participates in DNA repair and gene transcription. The Nipped-B-Mau2 protein complex loads cohesin onto chromosomes and the Pds5-Wapl complex removes cohesin. Pds5 is also essential for sister chromatid cohesion, indicating that it has functions beyond cohesin removal. The Brca2 DNA repair protein interacts with Pds5, but the roles of this complex beyond DNA repair are unknown. Here we show that Brca2 opposes Pds5 function in sister chromatid cohesion by assaying precocious sister chromatid separation in metaphase spreads of cultured cells depleted for these proteins. By genome-wide chromatin immunoprecipitation we find that Pds5 facilitates SA cohesin subunit association with DNA replication origins and that Brca2 inhibits SA binding, mirroring their effects on sister chromatid cohesion. Cohesin binding is maximal at replication origins and extends outward to occupy active genes and regulatory sequences. Pds5 and Wapl, but not Brca2, limit the distance that cohesin extends from origins, thereby determining which active genes, enhancers and silencers bind cohesin. Using RNA-seq we find that Brca2, Pds5 and Wapl influence the expression of most genes sensitive to Nipped-B and cohesin, largely in the same direction. These findings demonstrate that Brca2 regulates sister chromatid cohesion and gene expression in addition to its canonical role in DNA repair and expand the known functions of accessory proteins in cohesin's diverse functions. PMID- 29447173 TI - Dynamic changes of SETD2, a histone H3K36 methyltransferase, in porcine oocytes, IVF and SCNT embryos. AB - SETD2 (SET domain containing protein 2) acts as a histone H3 lysine 36 (H3K36) specific methyltransferase and may play important roles in active gene transcription in human cells. However, its expression and role in porcine oocytes and preimplantation embryos are not well understood. Here, we used immunofluorescence and laser scanning confocal microscopy to examine SETD2 expression in porcine fetal fibroblasts, oocytes, and preimplantation embryos derived from in vitro fertilization (IVF), parthenogenetic activation (PA), and somatic cell nuclear transfer (SCNT). In porcine fetal fibroblasts, SETD2 expression was detected in interphase cells, but not in M (mitotic)-phase cells. The SETD2 signal was observed in non-surrounded nucleolus (NSN)-stage oocytes, but not in surrounded nucleolus (SN)-, metaphase I (MI)-, or metaphase II (MII) stage oocytes. The SETD2 signal was detectable in sperm, and undetectable immediately after fertilization, detectable at the 2-cell stage, and peaked at the 4-cell stage of IVF embryos in which porcine embryonic genome is activated. Similar to the pattern found in IVF embryos, the SETD2 signal was absent from PA embryos at the 1-cell stage, but it was detected at the 2-cell stage and thereafter maintained to the blastocyst stage. Interestingly, unlike the IVF and PA embryos, the SETD2 signal was detected throughout the development of SCNT embryos, including at the 1-cell stage. These data suggest that SETD2 may be functional for embryonic gene transcription in porcine preimplantation embryos. It is further speculated that the aberrant expression of SETD2 at the 1-cell stage of porcine SCNT embryos may be a factor in the low efficiency of cloning in pig. PMID- 29447174 TI - Long-term cardiovascular risk of hypertensive events in emergency department: A population-based 10-year follow-up study. AB - BACKGROUND: Hypertension-related visits to the emergency department (ED) are increasing every year. Thus, ED could play a significant role in detecting hypertension and providing necessary interventions. However, it is not known whether a hypertensive event observed in the ED is an independent risk factor for future major adverse cardiovascular events (MACE). METHODS: A population-based observational study was conducted using a nationally representative cohort that contained the claim data of 1 million individuals from 2002 to 2013. We included non-critical ED visits without any history of MACE, and compared the new occurrences of MACE according to the presence of hypertensive events using extended Cox regression model. The disease-modifying effect of a follow-up visit was assessed by analyzing the interaction between hypertensive event and follow up visit. RESULTS: Among 262,927 first non-critical ED visits during the study period (from 2004 to 2013), 6,243 (2.4%) visits were accompanied by a hypertensive event. The hypertensive event group had a higher risk of having a first MACE at 3 pre-specified intervals: 0-3 years (HR, 4.25; 95% CI, 3.83-4.71; P<0.001), 4-6 years (HR, 3.65; 95% CI, 3.14-4.24; P<0.001), and 7-10 years (HR, 3.20; 95% CI, 2.50-4.11; P<0.001). Follow-up visits showed significant disease modifying effect at 2 intervals: 0-3 years (HR 0.65, 95% CI, 0.50-0.83) and 4-7 years (HR 0.68, 95% CI, 0.48-0.95). CONCLUSIONS: A hypertensive event in the ED is an independent risk factor for MACE, and follow-up visits after the event can significantly modify the risk.

AB - People vary at most levels, from the molecular to the cognitive, and the shape of the hard palate (the bony roof of the mouth) is no exception. The patterns of variation in the hard palate are important for the forensic sciences and (palaeo)anthropology, and might also play a role in speech production, both in pathological cases and normal variation. Here we describe a method based on Bezier curves, whose main aim is to generate possible shapes of the hard palate in humans for use in computer simulations of speech production and language evolution. Moreover, our method can also capture existing patterns of variation using few and easy-to-interpret parameters, and fits actual data obtained from MRI traces very well with as little as two or three free parameters. When compared to the widely-used Principal Component Analysis (PCA), our method fits actual data slightly worse for the same number of degrees of freedom. However, it is much better at generating new shapes without requiring a calibration sample, its parameters have clearer interpretations, and their ranges are grounded in geometrical considerations. PMID- 29447176 TI - Cost-effectiveness of prenatal food and micronutrient interventions on under-five mortality and stunting: Analysis of data from the MINIMat randomized trial, Bangladesh. AB - INTRODUCTION: Nutrition interventions may have favourable as well as unfavourable effects. The Maternal and Infant Nutrition Interventions in Matlab (MINIMat), with early prenatal food and micronutrient supplementation, reduced infant mortality and were reported to be very cost-effective. However, the multiple micronutrients (MMS) supplement was associated with an increased risk of stunted growth in infancy and early childhood. This unfavourable outcome was not included in the previous cost-effectiveness analysis. The aim of this study is to evaluate whether the MINIMat interventions remain cost-effective in view of both favourable (decreased under-five-years mortality) and unfavourable (increased stunting) outcomes. METHOD: Pregnant women in rural Bangladesh, where food insecurity still is prevalent, were randomized to early (E) or usual (U) invitation to be given food supplementation and daily doses of 30 mg, or 60 mg iron with 400 MUg of folic acid, or MMS with 15 micronutrients including 30 mg iron and 400 MUg of folic acid. E reduced stunting at 4.5 years compared with U, MMS increased stunting at 4.5 years compared with Fe60, while the combination EMMS reduced infant mortality compared with UFe60. The outcome measure used was disability adjusted life years (DALYs), a measure of overall disease burden that combines years of life lost due to premature mortality (under five-year mortality) and years lived with disability (stunting). Incremental cost effectiveness ratios were calculated using cost data from already published studies. RESULTS: By incrementing UFe60 (standard practice) to EMMS, one DALY could be averted at a cost of US$24. CONCLUSION: When both favourable and unfavourable outcomes were included in the analysis, early prenatal food and multiple micronutrient interventions remained highly cost effective and seem to be meaningful from a public health perspective. PMID- 29447177 TI - Physician prescribing of opioid agonist treatments in provincial correctional facilities in Ontario, Canada: A survey. AB - BACKGROUND: Substance use and substance use disorders are common in people who experience detention or incarceration in Canada, and opioid agonist treatment (OAT) may reduce the harms associated with substance use disorders. We aimed to define current physician practice in provincial correctional facilities in Ontario with respect to prescribing OAT and to identify potential barriers and facilitators to prescribing OAT. METHODS: We invited all physicians practicing in the 26 provincial correctional facilities for adults in Ontario to participate in an online survey. RESULTS: Twenty-seven physicians participated, with representation from most correctional facilities in Ontario. Of participating physicians, 52% reported prescribing methadone and 48% reported prescribing buprenorphine/naloxone to patients in provincial correctional facilities. Nineteen percent of participants reported initiating methadone treatment and 11% reported initiating buprenorphine/naloxone for patients in custody. Participants identified multiple barriers to initiating OAT in provincial correctional facilities including concerns about medication diversion and safety, concerns about initiating treatment in patients who are not currently using opioids, lack of linkage with community-based providers and the Ministry of Community Safety and Correctional Services policy. Identified facilitators to initiating OAT were support from institutional health care staff and administrative staff, adequate resources for program delivery and access to linkage with community-based OAT providers. CONCLUSIONS: This study identifies opportunities to improve OAT programs and to improve access to OAT for persons in provincial correctional facilities in Ontario. PMID- 29447178 TI - Joint ancestry and association test indicate two distinct pathogenic pathways involved in classical dengue fever and dengue shock syndrome. AB - Ethnic diversity has been long considered as one of the factors explaining why the severe forms of dengue are more prevalent in Southeast Asia than anywhere else. Here we take advantage of the admixed profile of Southeast Asians to perform coupled association-admixture analyses in Thai cohorts. For dengue shock syndrome (DSS), the significant haplotypes are located in genes coding for phospholipase C members (PLCB4 added to previously reported PLCE1), related to inflammation of blood vessels. For dengue fever (DF), we found evidence of significant association with CHST10, AHRR, PPP2R5E and GRIP1 genes, which participate in the xenobiotic metabolism signaling pathway. We conducted functional analyses for PPP2R5E, revealing by immunofluorescence imaging that the coded protein co-localizes with both DENV1 and DENV2 NS5 proteins. Interestingly, only DENV2-NS5 migrated to the nucleus, and a deletion of the predicted top linking motif in NS5 abolished the nuclear transfer. These observations support the existence of differences between serotypes in their cellular dynamics, which may contribute to differential infection outcome risk. The contribution of the identified genes to the genetic risk render Southeast and Northeast Asian populations more susceptible to both phenotypes, while African populations are best protected against DSS and intermediately protected against DF, and Europeans the best protected against DF but the most susceptible against DSS. PMID- 29447179 TI - Isolation and identification of new bacterial stains producing equol from Pueraria lobata extract fermentation. AB - Equol is a nonsteroidal estrogen that is produced by intestinal bacterial metabolism. Equol and equol-producing bacteria have been extensively investigated with soybean-based materials under anaerobic condition. In this study, an under appreciated plant material, Pueraria lobata, was used to find new bacterial strains that produce equol under aerobic conditions. Three new intestinal bacteria, CS1, CS2, and CS3, were isolated, and internal transcribed spacer analysis revealed that belonging to genus Pediococcus and Lactobacillus. HPLC analysis showed that these strains produced equol or its related intermediates when fermenting P. lobata extract. In comparison to fermentation of P. lobata extract, soybean germ extract was also fermented. While the isolated strains did not produce equol in this extract, they produced other equol-related precursors. To test the modularity effect of these fermentation mixtures with the newly isolated bacteria, MCF-7 cell proliferation assay was performed, which showed that all extracts fermented with those strains has a modularity effect. Fermenting P. lobata extract with strain CS1 demonstrated the best modularity effect. PMID- 29447180 TI - Experimental research on the structural instability mechanism and the effect of multi-echelon support of deep roadways in a kilometre-deep well. AB - We study the structural instability mechanism and effect of a multi-echelon support in very-deep roadways. We conduct a scale model test for analysing the structural failure mechanism and the effect of multi-echelon support of roadways under high horizontal stress. Mechanical bearing structures are classified according to their secondary stress distribution and the strength degradation of the surrounding rock after roadway excavation. A new method is proposed by partitioning the mechanical bearing structure of the surrounding rock into weak, key and main coupling bearing stratums. In the surrounding rock, the main bearing stratum is the plastic reshaping and flowing area. The weak bearing stratum is the peeling layer or the caving part. And the key bearing stratum is the shearing and yielding area. The structural fracture mechanism of roadways is considered in analysing the bearing structure instability of the surrounding rock, and multi echelon support that considers the structural characteristics of roadway bearings is proposed. Results of the experimental study indicate that horizontal pressure seriously influences the stability of the surrounding rock, as indicated by extension of the weak bearing area and the transfer of the main and key bearing zones. The falling roof, rib spalling, and floor heave indicate the decline of the bearing capacity of surrounding rock, thereby causing roadway structural instability. Multi-echelon support is proposed according to the mechanical bearing structure of the surrounding rock without support. The redesigned support can reduce the scope of the weak bearing area and limit the transfer of the main and key bearing areas. Consequently, kilometre-deep roadway disasters, such as wedge roof caving, floor heave, and rib spalling, can be avoided to a certain degree, and plastic flow in the surrounding rock is relieved. The adverse effect of horizontal stress on the vault, spandrel and arch foot decreases. The stability of the soft rock surrounding the roadways is maintained. PMID- 29447181 TI - Innate immune responses following Kawasaki disease and toxic shock syndrome. AB - The pathogenesis of Kawasaki disease (KD) remains unknown and there is accumulating evidence for the importance of the innate immune system in initiating and mediating the host inflammatory response. We compared innate immune responses in KD and toxic shock syndrome (TSS) participants more than two years after their acute illness with control participants to investigate differences in their immune phenotype. Toxic shock syndrome shares many clinical features with KD; by including both disease groups we endeavoured to explore changes in innate immune responses following acute inflammatory illnesses more broadly. We measured the in vitro production of interferon (IFN)-gamma, tumour necrosis factor (TNF)-alpha, interleukin (IL)-1beta, IL-6, IL-1 receptor antagonist (IL-1ra), and IL-10 following whole blood stimulation with toll-like receptor and inflammasome ligands in 52 KD, 20 TSS, and 53 control participants in a case-control study. Analyses were adjusted for age, sex, and unstimulated cytokine concentrations. Compared to controls, KD participants have reduced IL 1ra production in response to stimulation with double stranded RNA (geometric mean ratio (GMR) 0.37, 95% CI 0.15, 0.89, p = 0.03) and increased IL-6 production in response to incubation with LyovecTM (GMR 5.48, 95% CI 1.77, 16.98, p = 0.004). Compared to controls, TSS participants have increased IFN-gamma production in response to peptidoglycan (GMR 4.07, 95% CI 1.82, 9.11, p = 0.001), increased IL-1beta production to lipopolysaccharide (GMR 1.64, 95% CI 1.13, 2.38, p = 0.01) and peptidoglycan (GMR 1.61, 95% CI 1.11, 2.33, p = 0.01), and increased IL-6 production to peptidoglycan (GMR 1.45, 95% CI 1.10, 1.92, p = 0.01). Years following the acute illness, individuals with previous KD or TSS exhibit a pro-inflammatory innate immune phenotype suggesting a possible underlying immunological susceptibility or innate immune memory. PMID- 29447182 TI - The impact of EGFR mutations on the incidence and survival of stages I to III NSCLC patients with subsequent brain metastasis. AB - Previous studies have demonstrated the association between EGFR mutations and distant metastasis. However, the association for subsequent brain metastasis (BM) in stages I-III non-small cell lung cancer (NSCLC) patients remains inconclusive. We conducted a retrospective analysis to clarify the impact of EGFR mutations on the incidence of BM and associated survival in patients with stage I-III NSCLC. A total of 491 patients screened for EGFR mutations were retrospectively enrolled. Brain MRI or CT was used to detect the BM. Cumulative incidence of subsequent BM and overall survival (OS) after diagnosis of BM were estimated by the Kaplan Meier method and compared using log-rank test. We performed Cox proportional hazard regression for predictors of subsequent BM and determinants of OS after BM. The cumulative incidence of BM seemed higher in patients harboring EGFR mutations than those without EGFR mutations although it did not reach statistical significance (hazard ratio [HR] = 1.75, 95% confidence interval [CI] = 0.73~1.81). After adjusting possible confounders, including age, smoking, stage, and tumor size, EGFR mutation became one of the predictors for subsequent BM (HR = 1.89, 95% CI = 1.12~3.17, p = 0.017). Though there was no statistical difference in survival after BM between patients with EGFR mutations and wild type EGFR (median survival: 17.8 vs. 12.2 months, HR = 0.79, 95% CI = 0.45-1.40), patients with EGFR 19 deletion (Del) tended to have a longer survival after BM than the non-EGFR 19 Del group (median survival: 29.4 vs. 14.3 months, HR 0.58, 95% CI = 0.32-1.09, p = 0.089). In conclusion, our data suggested EGFR mutation to be one of the predictors for subsequent BM in stage I-III patients. Given the small sample size, more studies are warranted to corroborate our results. PMID- 29447183 TI - A mass-density model can account for the size-weight illusion. AB - When judging the heaviness of two objects with equal mass, people perceive the smaller and denser of the two as being heavier. Despite the large number of theories, covering bottom-up and top-down approaches, none of them can fully account for all aspects of this size-weight illusion and thus for human heaviness perception. Here we propose a new maximum-likelihood estimation model which describes the illusion as the weighted average of two heaviness estimates with correlated noise: One estimate derived from the object's mass, and the other from the object's density, with estimates' weights based on their relative reliabilities. While information about mass can directly be perceived, information about density will in some cases first have to be derived from mass and volume. However, according to our model at the crucial perceptual level, heaviness judgments will be biased by the objects' density, not by its size. In two magnitude estimation experiments, we tested model predictions for the visual and the haptic size-weight illusion. Participants lifted objects which varied in mass and density. We additionally varied the reliability of the density estimate by varying the quality of either visual (Experiment 1) or haptic (Experiment 2) volume information. As predicted, with increasing quality of volume information, heaviness judgments were increasingly biased towards the object's density: Objects of the same density were perceived as more similar and big objects were perceived as increasingly lighter than small (denser) objects of the same mass. This perceived difference increased with an increasing difference in density. In an additional two-alternative forced choice heaviness experiment, we replicated that the illusion strength increased with the quality of volume information (Experiment 3). Overall, the results highly corroborate our model, which seems promising as a starting point for a unifying framework for the size-weight illusion and human heaviness perception. PMID- 29447184 TI - Greenery in the university environment: Students' preferences and perceived restoration likelihood. AB - A large body of evidence shows that interaction with greenery can be beneficial for human stress reduction, emotional states, and improved cognitive function. It can, therefore, be expected that university students might benefit from greenery in the university environment. Before investing in real-life interventions in a university environment, it is necessary to first explore students' perceptions of greenery in the university environment. This study examined (1) preference for university indoor and outdoor spaces with and without greenery (2) perceived restoration likelihood of university outdoor spaces with and without greenery and (3) if preference and perceived restoration likelihood ratings were modified by demographic characteristics or connectedness to nature in Dutch university students (N = 722). Digital photographic stimuli represented four university spaces (lecture hall, classroom, study area, university outdoor space). For each of the three indoor spaces there were four or five stimuli conditions: (1) the standard design (2) the standard design with a colorful poster (3) the standard design with a nature poster (4) the standard design with a green wall (5) the standard design with a green wall plus interior plants. The university outdoor space included: (1) the standard design (2) the standard design with seating (3) the standard design with colorful artifacts (4) the standard design with green elements (5) the standard design with extensive greenery. Multi-level analyses showed that students gave higher preference ratings to the indoor spaces with a nature poster, a green wall, or a green wall plus interior plants than to the standard designs and the designs with the colorful posters. Students also rated preference and perceived restoration likelihood of the outdoor spaces that included greenery higher than those without. Preference and perceived restoration likelihood were not modified by demographic characteristics, but students with strong connectedness to nature rated preference and perceived restoration likelihood overall higher than students with weak connectedness to nature. The findings suggest that students would appreciate the integration of greenery in the university environment. PMID- 29447185 TI - Egg turning behavior and incubation temperature in Forster's terns in relation to mercury contamination. AB - Egg turning behavior is an important determinant of egg hatchability, but it remains relatively understudied. Here, we examined egg turning rates and egg temperatures in Forster's terns (Sterna forsteri). We used artificial eggs containing a data logger with a 3-D accelerometer, a magnetometer, and a temperature thermistor to monitor parental incubation behavior of 131 tern nests. Overall, adults turned their eggs an average (+/-SD) of 3.8 +/- 0.8 turns h-1, which is nearly two times higher than that of other seabirds. Egg turning rates increased with nest initiation date. We also examined egg turning rates and egg temperatures in relation to egg mercury contamination. Mercury contamination has been shown to be associated with reduced egg hatchability, and we hypothesized that mercury may decrease egg hatchability via altered egg turning behavior by parents. Despite the high variability in egg turning rates among individuals, the rate of egg turning was not related to mercury concentrations in sibling eggs. These findings highlight the need for further study concerning the potential determinants of egg turning behavior. PMID- 29447186 TI - Can an experimental white noise task assess psychosis vulnerability in adult healthy controls? AB - BACKGROUND: This is an extension of a paper published earlier. We investigated the association between the tendency to detect speech illusion in random noise and levels of positive schizotypy in a sample of 185 adult healthy controls. MATERIALS AND METHODS: Subclinical positive, negative and depressive symptoms were assessed with the Community Assessment of Psychic Experiences (CAPE); positive and negative schizotypy was assessed with the Structured Interview for Schizotypy-Revised (SIS-R). RESULTS: Speech illusions were associated with positive schizotypy (OR: 4.139, 95% CI: 1.074-15.938; p = 0.039) but not with negative schizotypy (OR: 1.151, 95% CI: 0.183-7.244; p = 0.881). However, the association of positive schizotypy with speech illusions was no longer significant after adjusting for age, sex and WAIS-III (OR: 2.577, 95% CI: 0.620 10.700; p = 0.192). Speech illusions were not associated with self-reported CAPE measures. CONCLUSIONS: The association between schizotypy and the tendency to assign meaning in random noise in healthy controls may be mediated by cognitive ability and not constitute an independent trait. PMID- 29447187 TI - Comparative study on the mechanical mechanism of confined concrete supporting arches in underground engineering. AB - In order to solve the supporting problem in underground engineering with high stress, square steel confined concrete (SQCC) supporting method is adopted to enhance the control on surrounding rocks, and the control effect is remarkable. The commonly used cross section shapes of confined concrete arch are square and circular. At present, designers have no consensus on which kind is more proper. To search for the answer, this paper makes an analysis on the mechanical properties of the two shapes of the cross-sections. A full-scale indoor comparative test was carried out on the commonly used straight-wall semi-circular SQCC arch and circular steel confined concrete arch (CCC arch). This test is based on self-developed full-scale test system for confined concrete arch. Our research, combining with the numerical analysis, shows: (1) SQCC arch is consistent with CCC arch in the deformation and failure mode. The largest damages parts are at the legs of both of them. (2) The SQCC arch's bearing capability is 1286.9 kN, and the CCC arch's ultimate bearing capability is 1072.4kN. Thus, the SQCC arch's bearing capability is 1.2 times that of the CCC arch. (3) The arches are subjected to combined compression and bending, bending moment is the main reason for the arch failure. The section moment of inertia of SQCC arch is 1.26 times of that of CCC arch, and the former is better than the latter in bending performance. The ultimate bearing capacity is positively correlated with the size of the moment of inertia. Based on the above research, the engineering suggestions are as follows: (1) To improve the bearing capacity of the arch, the cross-sectional shape of the chamber should be optimized and the arch bearing mode changed accordingly. (2) The key damaged positions, such as the arch leg, should be reinforced, optimizing the state of force on the arch. SQCC arches should be used for supporting in underground engineering, which is under stronger influence of the bending moment and non-uniform load on the supporting arches. The research results could provide a theoretical basis for the design of confined concrete support in underground engineering. PMID- 29447188 TI - Comparing deep learning and concept extraction based methods for patient phenotyping from clinical narratives. AB - In secondary analysis of electronic health records, a crucial task consists in correctly identifying the patient cohort under investigation. In many cases, the most valuable and relevant information for an accurate classification of medical conditions exist only in clinical narratives. Therefore, it is necessary to use natural language processing (NLP) techniques to extract and evaluate these narratives. The most commonly used approach to this problem relies on extracting a number of clinician-defined medical concepts from text and using machine learning techniques to identify whether a particular patient has a certain condition. However, recent advances in deep learning and NLP enable models to learn a rich representation of (medical) language. Convolutional neural networks (CNN) for text classification can augment the existing techniques by leveraging the representation of language to learn which phrases in a text are relevant for a given medical condition. In this work, we compare concept extraction based methods with CNNs and other commonly used models in NLP in ten phenotyping tasks using 1,610 discharge summaries from the MIMIC-III database. We show that CNNs outperform concept extraction based methods in almost all of the tasks, with an improvement in F1-score of up to 26 and up to 7 percentage points in area under the ROC curve (AUC). We additionally assess the interpretability of both approaches by presenting and evaluating methods that calculate and extract the most salient phrases for a prediction. The results indicate that CNNs are a valid alternative to existing approaches in patient phenotyping and cohort identification, and should be further investigated. Moreover, the deep learning approach presented in this paper can be used to assist clinicians during chart review or support the extraction of billing codes from text by identifying and highlighting relevant phrases for various medical conditions. PMID- 29447189 TI - Drought response of Mucuna pruriens (L.) DC. inoculated with ACC deaminase and IAA producing rhizobacteria. AB - Drought is one of the major constraints limiting agricultural production worldwide and is expected to increase in the future. Limited water availability causes significant effects to plant growth and physiology. Plants have evolved different traits to mitigate the stress imposed by drought. The presence of plant growth-promoting rhizobacteria (PGPR) could play an important role in improving plant performances and productivity under drought. These beneficial microorganisms colonize the rhizosphere of plants and increase drought tolerance by lowering ethylene formation. In the present study, we demonstrate the potential to improve the growth of velvet bean under water deficit conditions of two different strains of PGPR with ACCd (1-Aminocyclopropane-1-Carboxylate deaminase) activity isolated from rainfed farming system. We compared uninoculated and inoculated plants with PGPR to assess: a) photosynthetic performance and biomass; b) ACC content and ethylene emission from leaves and roots; c) leaf isoprene emission. Our results provided evidence that under drought conditions inoculation with PGPR containing the ACCd enzyme could improve plant growth compared to untreated plants. Ethylene emission from roots and leaves of inoculated velvet bean plants was significantly lower than uninoculated plants. Moreover, isoprene emission increased with drought stress progression and was higher in inoculated plants compared to uninoculated counterparts. These findings clearly illustrate that selected PGPR strains isolated from rainfed areas could be highly effective in promoting plant growth under drought conditions by decreasing ACC and ethylene levels in plants. PMID- 29447190 TI - The incidence and factors of hip fractures and subsequent morbidity in Taiwan: An 11-year population-based cohort study. AB - Hip fractures are a major problem to elder population, but subsequent morbidity is unclear about environmental factors and socioeconomic conditions. The study aims to investigate the incidence of hip fractures treated by the surgery; to compare the sequelae and temporal trends of hip fractures; to evaluate the seasonal effects in the subsequent short-term and long-term morbidities after hip fractures. A cohort study design is conducted using national health research datasets between 2000 and 2010. The ICD-9-CM diagnostic codes were utilized to investigate the incidence of hip fractures and the corresponding treatments. Hierarchical modeling was used to analyze the factors associated with various types of hip fractures. The results indicated that females had a lower incidence in the 30-44 age group, but a significantly higher incidence than males among those aged 60 years or older (adjusted rates 232.1 vs. 100.3 per 100,000 persons, p<0.001). The incidence of hip fractures in the low-income group showed no significant difference compared to that in the general population. There was a temporal trend of a 8.6% increase in the incidence of all types of hip fractures over the period of 2000-2010. A summer-winter variation is observed among the elderly. Hip fractures and subsequent morbidity are increasing in Taiwan's aging society. Older age, female gender, and time periods were independent risk factors for subsequent morbidities after surgical treatment. The result of this study is useful to the healthcare policy makers and to raise the public awareness of hip fractures.

AB - Euglena gracilis Z (Euglena) is a unicellular, photosynthesizing, microscopic green alga. It contains several nutrients such as vitamins, minerals, and unsaturated fatty acids. In this study, to verify the potential role of Euglena consumption on human health and obesity, we evaluated the effect of Euglena on human adipose-derived stem cells. We prepared a Euglena extract and evaluated its effect on cell growth and lipid accumulation, and found that cell growth was promoted by the addition of the Euglena extract. Interestingly, intracellular lipid accumulation was inhibited in a concentration-dependent manner. Quantitative real-time PCR analysis and western blotting analysis indicated that the Euglena extract suppressed adipocyte differentiation by inhibiting the gene expression of the master regulators peroxisome proliferator-activated receptor gamma (PPARgamma) and one of three CCAAT-enhancer-binding proteins (C/EBPalpha). Further Oil Red O staining experiments indicated that the Euglena extract inhibited the early stage of adipocyte-differentiation. Consistent with these results, we observed that down-regulation of gene expression was involved in the early stage of adipogenesis represented by the sterol regulatory element binding protein 1 c (SREBP1c), two of three CCAAT-enhancer-binding proteins (C/EBPbeta, C/EBPdelta), and the cAMP regulatory element-binding protein (CREB). Taken together, these data suggest that Euglena extract is a promising candidate for the development of a new therapeutic treatment for obesity.

AB - Preparing for intensifying threats of emergencies in unexpected, dangerous, and serious natural or man-made events, and consequent management of the situation, is highly demanding in terms of coordinating the personnel and resources to support human lives and the environment. This necessitates prompt action to manage the uncertainties and risks imposed by such extreme events, which requires collaborative operation among different stakeholders (i.e., the personnel from both the state and local communities). This research aims to find a way to enhance the coordination of multi-organizational response operations. To do so, this manuscript investigates the role of participants in the formed coordination response network and also the emergence and temporal dynamics of the network. By analyzing an inter-personal response coordination operation to an extreme bushfire event, the networks' and participants' structural change is evaluated during the evolution of the operation network over four time durations. The results reveal that the coordination response network becomes more decentralized over time due to the high volume of communication required to exchange information. New emerging communication structures often do not fit the developed plans, which stress the need for coordination by feedback in addition to by plan. In addition, we find that the participant's brokering role in the response operation network identifies a formal and informal coordination role. This is useful for comparison of network structures to examine whether what really happens during response operations complies with the initial policy.

AB - The basal media M199 or MEM was utilized in the classical method of vitro culture of glochidia where 1-5% CO2 was required to maintain stable physiological pH for completion of non-parasitic metamorphosis. The classical method encounters a great challenge to those glochidia which undergo development of visceral tissue but significantly increase in size during metamorphosis. The improved in vitro culture techniques and classical methods were firstly compared for non-parasitic metamorphosis and development of glochidia in pink heelsplitter. Based on the improved method, the optimal vitro culture media was further selected from 14 plasmas or sera, realizing the non-parasitic metamorphosis of axe-head glochidia for the first time. The results showed that addition of different plasma (serum) had significant effect on glochidial metamorphosis in pink heelsplitter. Only glochidia in the skewband grunt and red drum groups could complete metamorphosis, the metamorphosis rate in skewband grunt was 93.3+/-3.1% at 24+/-0.5 degrees C, significantly higher than in marine and desalinated red drum. Heat-inactivated treatment on the plasma of yellow catfish and Barbus capito had significant effect on glochidia survival and shell growth. The metamorphosis rate also varied among different gravid period, and generally decreased with gravid time. Further comparison of free amino acid and fatty acid indicated that the taurine of high concentration was the only amino acid that might promote the rapid growth of glochidial shell, and the lack of adequate DPA and DHA might be an important reason leading to the abnormal foot and visceral development. Combined with our results of artificial selection of host fish, we tentatively established the mechanism of its host specialists in pink heelsplitter for the first time. This is the first report on non-parasite metamorphosis of axe-head glochidia based on our improved vitro culture method, which should provide important reference to fundamental theory research of glochidia metamorphosis and also benefit for better understand of mechanism of host specialists and generalists of Unionidae species. PMID- 29447193 TI - The quality of instruments to assess the process of shared decision making: A systematic review. AB - OBJECTIVE: To inventory instruments assessing the process of shared decision making and appraise their measurement quality, taking into account the methodological quality of their validation studies. METHODS: In a systematic review we searched seven databases (PubMed, Embase, Emcare, Cochrane, PsycINFO, Web of Science, Academic Search Premier) for studies investigating instruments measuring the process of shared decision making. Per identified instrument, we assessed the level of evidence separately for 10 measurement properties following a three-step procedure: 1) appraisal of the methodological quality using the COnsensus-based Standards for the selection of health status Measurement INstruments (COSMIN) checklist, 2) appraisal of the psychometric quality of the measurement property using three possible quality scores, 3) best-evidence synthesis based on the number of studies, their methodological and psychometrical quality, and the direction and consistency of the results. The study protocol was registered at PROSPERO: CRD42015023397. RESULTS: We included 51 articles describing the development and/or evaluation of 40 shared decision-making process instruments: 16 patient questionnaires, 4 provider questionnaires, 18 coding schemes and 2 instruments measuring multiple perspectives. There is an overall lack of evidence for their measurement quality, either because validation is missing or methods are poor. The best-evidence synthesis indicated positive results for a major part of instruments for content validity (50%) and structural validity (53%) if these were evaluated, but negative results for a major part of instruments when inter-rater reliability (47%) and hypotheses testing (59%) were evaluated. CONCLUSIONS: Due to the lack of evidence on measurement quality, the choice for the most appropriate instrument can best be based on the instrument's content and characteristics such as the perspective that they assess. We recommend refinement and validation of existing instruments, and the use of COSMIN-guidelines to help guarantee high-quality evaluations. PMID- 29447195 TI - Hydrological and biogeochemical response of the Mediterranean Sea to freshwater flow changes for the end of the 21st century. AB - We evaluate the changes on the hydrological (temperature and salinity) and biogeochemical (phytoplankton biomass) characteristics of the Mediterranean Sea induced by freshwater flow modifications under two different scenarios for the end of the 21st century. An ensemble of four regional climate model realizations using different global circulation models at the boundary and different emission scenarios are used to force a single ocean model for the Mediterranean Sea. Freshwater flow is modified according to the simulated changes in the precipitation rates for the different rivers' catchment regions. To isolate the effect resulting from a change in freshwater flow, model results are evaluated against a 'baseline' simulation realized assuming a constant inflow equivalent to climatologic values. Our model results indicate that sea surface salinity could be significantly altered by freshwater flow modification in specific regions and that the affected area and the sign of the anomaly are highly dependent on the used climate model and emission scenario. Sea surface temperature and phytoplankton biomass, on the contrary, show no coherent spatial pattern but a rather widespread scattered response. We found in open-water regions a significant negative relationship between sea surface temperature anomalies and phytoplankton biomass anomalies. This indicates that freshwater flow modification could alter the vertical stability of the water column throughout the Mediterranean Sea, by changing the strength of vertical mixing and consequently upper water fertilization. In coastal regions, however, the correlation between sea temperature anomalies and phytoplankton biomass is positive, indicating a larger importance of the physiological control of growth rates by temperature. PMID- 29447196 TI - Nasopharyngeal carriage of Streptococcus pneumoniae among HIV-infected and uninfected children <5 years of age before introduction of pneumococcal conjugate vaccine in Mozambique. AB - Nasopharyngeal carriage is a precursor for pneumococcal disease and can be useful for evaluating pneumococcal conjugate vaccine (PCV) impact. We studied pre-PCV pneumococcal carriage among HIV-infected and -uninfected children in Mozambique. Between October 2012 and March 2013, we enrolled HIV-infected children age <5 years presenting for routine care at seven HIV clinics in 3 sites, including Maputo (urban-south), Nampula (urban-north), and Manhica (rural-south). We also enrolled a random sample of HIV-uninfected children <5 years old from a demographic surveillance site in Manhica. A single nasopharyngeal swab was obtained and cultured following enrichment in Todd Hewitt broth with yeast extract and rabbit serum. Pneumococcal isolates were serotyped by Quellung reaction and multiplex polymerase chain reaction. Factors associated with pneumococcal carriage were examined using logistic regression. Overall pneumococcal carriage prevalence was 80.5% (585/727), with similar prevalences among HIV-infected (81.5%, 339/416) and HIV-uninfected (79.1%, 246/311) children, and across age strata. Among HIV-infected, after adjusting for recent antibiotic use and hospitalization, there was no significant association between study site and colonization: Maputo (74.8%, 92/123), Nampula (83.7%, 82/98), Manhica (84.6%, 165/195). Among HIV-uninfected, report of having been born to an HIV-infected mother was not associated with colonization. Among 601 pneumococcal isolates from 585 children, serotypes 19F (13.5%), 23F (13.1%), 6A (9.2%), 6B (6.2%) and 19A (5.2%) were most common. The proportion of serotypes included in the 10- and 13 valent vaccines was 44.9% and 61.7%, respectively, with no significant differences by HIV status or age group. Overall 36.9% (n = 268) of children were colonized with a PCV10 serotype and 49.7% (n = 361) with a PCV13 serotype. Pneumococcal carriage was common, with little variation by geographic region, age, or HIV status. PCV10 was introduced in April 2013; ongoing carriage studies will examine the benefits of PCV10 among HIV-infected and-uninfected children. PMID- 29447198 TI - EW-7197 eluting nano-fiber covered self-expandable metallic stent to prevent granulation tissue formation in a canine urethral model. AB - PURPOSE: To evaluate an EW-7197-eluting nanofiber-covered stent (NFCS) for suppressing granulation tissue formation after stent placement in a canine urethral model. MATERIALS AND METHODS: All experiments were approved by the committee of animal research. A total of 12 NFCSs were placed in the proximal and distal urethras of six dogs. Dogs were divided into two groups with 3 dogs each. The control stent (CS) group received NFCSs and the drug stent (DS) group received EW-7197 (1000 MUg)-eluting NFCSs. All dogs were sacrificed 8 weeks after stent placement Histologic findings of the stented urethra were compared using the Mann-Whitney U test. RESULTS: Stent placement was technically successful in all dogs without procedure-related complications. On urethrographic analysis, the mean luminal diameter was significantly larger in the DS group than in the CS group at 4 and 8 weeks after stent placement (all p < 0.001). On histological examination, mean thicknesses of the papillary projection, thickness of submucosal fibrosis, number of epithelial layers, and degree of collagen deposition were significantly lower in the DS group than in the CS group (all p < 0.001), whereas the mean degree of inflammatory cell infiltration was not significantly different (p > 0.05). CONCLUSION: The EW-7197-eluting NFCS is effective and safe for suppressing granulation tissue formation after stent placement in a canine urethral model. PMID- 29447197 TI - Shotgun proteomics deciphered age/division of labor-related functional specification of three honeybee (Apis mellifera L.) exocrine glands. AB - The honeybee (Apis mellifera L.) uses various chemical signals produced by the worker exocrine glands to maintain the functioning of its colony. The roles of worker postcerebral glands (PcGs), thoracic glands (TGs), and mandibular glands (MGs) and the functional changes they undergo according to the division of labor from nursing to foraging are not as well studied. To comprehensively characterize the molecular roles of these glands in workers and their changes according to the division of labor of workers, we analyzed the proteomes of PcGs, TGs, and MGs from nurse bees and foragers using shotgun proteomics technology. We identified approximately 2000 proteins from each of the nurse bee or forager glands and highlighted the features of these glands at the molecular level by semiquantitative enrichment analyses of frequently detected, gland-selective, and labor-selective proteins. First, we found the high potential to produce lipids in PcGs and MGs, suggesting their relation to pheromone production. Second, we also found the proton pumps abundant in TGs and propose some transporters possibly related to the saliva production. Finally, our data unveiled candidate enzymes involved in labor-dependent acid production in MGs. PMID- 29447200 TI - Discovery of two new species of Crotalaria (Leguminosae, Crotalarieae) from Western Ghats, India. AB - Two new species of Fabaceae-Papilionoideae are described and illustrated. Crotalaria suffruticosa from Karul Ghat region of Maharashtra is morphologically close to C. albida and C. epunctata. C. multibracteata from Panhala region of Maharashtra resembles C. vestita. C. suffruticosa differs from C. albida and C. epunctata in its habit, leaf, inflorescence, callosity, keel type, stigma, style morphology and number of seeds/pod. To test if the new species differ from their morphologically most similar species, we measured various traits and performed a Principal Component Analysis (PCA). This analysis shows that the new species differs from similar species in gross morphology for several diagnostic traits and showed correlations between the variables or distance among groups and estimated the contribution of each character. Phylogenetic analyses were also conducted based on nuclear (ITS) and plastid (matK) markers. The analyses revealed nucleotide differences between the new species and their close allies attributing to their distinctiveness. A map and key including all species of Crotalaria from Maharashtra state are provided. Conservation status of the two new species have also been assessed. PMID- 29447199 TI - Short-term repeated HRV-16 exposure results in an attenuated immune response in vivo in humans. AB - INTRODUCTION: Naturally, development of adaptive immunity following HRV infection affects the immune response. However, it is currently unclear whether or not HRV re-exposure within a short time frame leads to an altered innate immune response. The "experimental cold model" is used to investigate the pathogenesis of HRV infection and allows us to investigate the effects of repeated exposure on both local and systemic innate immunity. METHODS: 40 healthy male and female (1:1) subjects were nasally inoculated with HRV-16 or placebo. One week later, all subjects received HRV-16. Baseline seronegative subjects (n = 18) were included for further analysis. RESULTS: Infection rate was 82%. Primary HRV infection induced a marked increase in viral load and IP-10 levels in nasal wash, while a similar trend was observed for IL-6 and IL-10. Apart from an increase in IP-10 plasma levels, HRV infection did not induce systemic immune effects nor lower respiratory tract inflammation. With similar viral load present during the second HRV challenge, IP-10 and IL-6 in nasal wash showed no increase, but gradually declined, with a similar trend for IL-10. CONCLUSION: Upon a second HRV challenge one week after the first, a less pronounced response for several innate immune parameters is observed. This could be the result of immunological tolerance and possibly increases vulnerability towards secondary infections. PMID- 29447201 TI - Estimation model for habitual 24-hour urinary-sodium excretion using simple questionnaires from normotensive Koreans. AB - This study was conducted to develop an equation for estimation of 24-h urinary sodium excretion that can serve as an alternative to 24-h dietary recall and 24-h urine collection for normotensive Korean adults. In total, data on 640 healthy Korean adults aged 19 to 69 years from 4 regions of the country were collected as a training set. In order to externally validate the equation developed from that training set, 200 subjects were recruited independently as a validation set. Due to heterogeneity by gender, we constructed a gender-specific equation for estimation of 24-h urinary-sodium excretion by using a multivariable linear regression model and assessed the performance of the developed equation in validation set. The best model consisted of age, body weight, dietary behavior ('eating salty food', 'Kimchi consumption', 'Korean soup or stew consumption', 'soy sauce or red pepper paste consumption'), and smoking status in men, and age, body weight, dietary behavior ('salt preference', 'eating salty food', 'checking sodium content for processed foods', 'nut consumption'), and smoking status in women, respectively. When this model was tested in the external validation set, the mean bias between the measured and estimated 24-h urinary-sodium excretion from Bland-Altman plots was -1.92 (95% CI: -113, 110) mmol/d for men and -1.51 (95% CI: -90.6, 87.6) mmol/d for women. The cut-points of sodium intake calculated based on the equations were >=4,000 mg/d for men and >=3,500 mg/d for women, with 89.8 and 76.6% sensitivity and 29.3 and 64.2% specificity, respectively. In this study, a habitual 24-hour urinary-sodium-excretion estimation model of normotensive Korean adults based on anthropometric and lifestyle factors was developed and showed feasibility for an asymptomatic population. PMID- 29447202 TI - Nitrogen isotopes suggest a change in nitrogen dynamics between the Late Pleistocene and modern time in Yukon, Canada. AB - A magnificent repository of Late Pleistocene terrestrial megafauna fossils is contained in ice-rich loess deposits of Alaska and Yukon, collectively eastern Beringia. The stable carbon (delta13C) and nitrogen (delta15N) isotope compositions of bone collagen from these fossils are routinely used to determine paleodiet and reconstruct the paleoecosystem. This approach requires consideration of changes in C- and N-isotope dynamics over time and their effects on the terrestrial vegetation isotopic baseline. To test for such changes between the Late Pleistocene and modern time, we compared delta13C and delta15N for vegetation and bone collagen and structural carbonate of some modern, Yukon, arctic ground squirrels with vegetation and bones from Late Pleistocene fossil arctic ground squirrel nests preserved in Yukon loess deposits. The isotopic discrimination between arctic ground squirrel bone collagen and their diet was measured using modern samples, as were isotopic changes during plant decomposition; Over-wintering decomposition of typical vegetation following senescence resulted in a minor change (~0-1 0/00) in delta13C of modern Yukon grasses. A major change (~2-10 0/00) in delta15N was measured for decomposing Yukon grasses thinly covered by loess. As expected, the collagen-diet C-isotope discrimination measured for modern samples confirms that modern vegetation delta13C is a suitable proxy for the Late Pleistocene vegetation in Yukon Territory, after correction for the Suess effect. The N-isotope composition of vegetation from the fossil arctic ground squirrel nests, however, is determined to be ~2.8 0/00 higher than modern grasslands in the region, after correction for decomposition effects. This result suggests a change in N dynamics in this region between the Late Pleistocene and modern time. PMID- 29447203 TI - Quantification of fetal organ volume and fat deposition following in utero exposure to maternal Western Diet using MRI. AB - PURPOSE: To examine the feasibility of using MRI to identify differences in liver size and fat deposition in fetal guinea pigs exposed to an in utero environment influenced by maternal consumption of a Western diet. MATERIALS AND METHODS: Female guinea pigs fed either an energy-dense Western Diet (WD), comprised of increased saturated fats and simple sugars, or a Control Diet (CD) from weaning through pregnancy, underwent MR scanning near term (~ 60 days; term ~ 69 days). Maternal weights were collected at mating and at MR scanning. T1-weighted, T2 weighted, and IDEAL water-fat images were acquired at 3 Tesla. The images were used to segment maternal adipose tissue, fetal liver, fetal brain, fetal adipose tissue, and total fetal volumes and to measure maternal and fetal hepatic fat fractions. RESULTS: Weights of WD sows were lower prior to pregnancy (P = .04), however their weight gain over pregnancy did not differ from the CD group (P = .98). The WD sows had less total adipose tissue (TAT) at MR scanning (P = .04), while hepatic fat content was significantly elevated (P = .04). When controlling for litter size, WD fetuses had larger livers (P = .02), smaller brains (P = .01), and increased total adipose tissue volume (P = .01) when normalized by fetal volume. The WD fetuses also had increased hepatic fat fractions compared to CD fetal livers (P < .001). CONCLUSION: Maternal Western Diet consumption prior to and during pregnancy induces differences in maternal liver fat content, fetal liver volume and liver fat storage, as well as changes in fetal adipose tissue deposition that can be measured in utero using MRI. PMID- 29447204 TI - Comparison of viral infection in healthcare-associated pneumonia (HCAP) and community-acquired pneumonia (CAP). AB - BACKGROUND: Although viruses are known to be the second most common etiological factor in community-acquired pneumonia (CAP), the respiratory viral profile of the patients with healthcare-associated pneumonia (HCAP) has not yet been elucidated. We investigated the prevalence and the clinical impact of respiratory virus infection in adult patients with HCAP. METHODS: Patients admitted with HCAP or CAP, between January and December 2016, to a tertiary referral hospital in Korea, were prospectively enrolled, and virus identification was performed using reverse-transcription polymerase chain reaction (RT-PCR). RESULTS: Among 452 enrolled patients (224 with HCAP, 228 with CAP), samples for respiratory viruses were collected from sputum or endotracheal aspirate in 430 (95.1%) patients and from nasopharyngeal specimens in 22 (4.9%) patients. Eighty-seven (19.2%) patients had a viral infection, and the proportion of those with viral infection was significantly lower in the HCAP than in the CAP group (13.8% vs 24.6%, p = 0.004). In both the HCAP and CAP groups, influenza A was the most common respiratory virus, followed by entero-rhinovirus. The seasonal distributions of respiratory viruses were also similar in both groups. In the HCAP group, the viral infection resulted in a similar length of hospital stay and in-hospital mortality as viral-bacterial coinfection and bacterial infection, and the CAP group showed similar results. CONCLUSIONS: The prevalence of viral infection in patients with HCAP was lower than that in patients with CAP, and resulted in a similar prognosis as viral-bacterial coinfection or bacterial infection. PMID- 29447205 TI - Aggressive fluid accumulation is associated with acute kidney injury and mortality in a cohort of patients with severe pneumonia caused by influenza A H1N1 virus. AB - INTRODUCTION: Fluid accumulation is associated with adverse outcomes such as acute kidney injury (AKI) in critically ill patients. This study aimed to describe the factors associated with AKI in individuals with influenza A H1N1 severe pneumonia, and explore the relation of fluid accumulation with AKI and mortality. MATERIAL AND METHODS: We reviewed medical records of individuals with influenza A H1N1 severe pneumonia and no history of chronic kidney disease, attending a national referral center for respiratory diseases between November 2014 and May 2015. Demographic information, risk factors for AKI, physiologic and laboratory data, outcomes and information on fluid intake and output were recorded. Categorical variables were compared using the chi-square test. Quantitative variables were compared using the Mann-Whitney test. Factors associated with AKI and mortality were identified by binary logistic regression. Linear models of fluid accumulation rates for individuals and groups were estimated using segmented linear regression. RESULTS: Of 60 patients studied, 43 developed AKI (71.6%). Male gender was protective for AKI (p = 0.019). AKI was associated with nephrotoxic drugs (p = 0.016); PEEP>10 cm H2O on admission (p = 0.031); mortality (p = 0.037); and fluid accumulation >=10% (fluid overload) at day 7 of hospitalization (p = 0.00026). Mortality was associated with older age (p = 0.009); nephrotoxic drugs (p = 0.034); and higher Pneumonia Severity Index score (112 vs. 76, p = 0.008) on admission. The Deceased-AKI group had a higher rate of fluid accumulation (expressed as ml/kg/body weight) than the Survivors-No AKI group during the study period of 7 days (Survivors-No AKI = 13.31 vs. Deceased-AKI = 22.76, p = 0.019). During the highest phase of fluid accumulation, the Survivors-No AKI group had a slower rate of fluid accumulation than the Survivors-AKI group (14.91 vs. 28.49, p = 0.001). CONCLUSIONS: A high rate of fluid accumulation was associated with AKI and mortality. We support the approach of resuscitation in acute illness, with an early transition to neutral and then negative fluid balances. PMID- 29447206 TI - Multiplex CRISPR/Cas9 system impairs HCMV replication by excising an essential viral gene. AB - Anti-HCMV treatments used in immunosuppressed patients reduce viral replication, but resistant viral strains can emerge. Moreover, these drugs do not target latently infected cells. We designed two anti-viral CRISPR/Cas9 strategies to target the UL122/123 gene, a key regulator of lytic replication and reactivation from latency. The singleplex strategy contains one gRNA to target the start codon. The multiplex strategy contains three gRNAs to excise the complete UL122/123 gene. Primary fibroblasts and U-251 MG cells were transduced with lentiviral vectors encoding Cas9 and one or three gRNAs. Both strategies induced mutations in the target gene and a concomitant reduction of immediate early (IE) protein expression in primary fibroblasts. Further detailed analysis in U-251 MG cells showed that the singleplex strategy induced 50% of indels in the viral genome, leading to a reduction in IE protein expression. The multiplex strategy excised the IE gene in 90% of all viral genomes and thus led to the inhibition of IE protein expression. Consequently, viral genome replication and late protein expression were reduced by 90%. Finally, the production of new viral particles was nearly abrogated. In conclusion, the multiplex anti-UL122/123 CRISPR/Cas9 system can target the viral genome efficiently enough to significantly prevent viral replication. PMID- 29447207 TI - Demography of a forest elephant population. AB - African forest elephants face severe threats from illegal killing for ivory and bushmeat and habitat conversion. Due to their cryptic nature and inaccessible range, little information on the biology of this species has been collected despite its iconic status. Compiling individual based monitoring data collected over 20 years from the Dzanga Bai population in Central African Republic, we summarize sex and age specific survivorship and female age specific fecundity for a cohort of 1625 individually identified elephants. Annual mortality (average = 3.5%) and natality (average = 5.3%) were lower and markedly less variable relative to rates reported for savanna elephant populations. New individuals consistently entered the study system, leading to a 2.5% average annual increase in the registered population. Calf sex ratios among known birth did not differ from parity. A weak seasonal signal in births was detected suggesting increased conceptions during the wet season. Inter-calf intervals and age of primiparity were longer relative to savanna elephant populations. Within the population, females between the ages of 25-39 demonstrated the shortest inter-calf intervals and highest fecundity, and previous calf sex had no influence on the interval. Calf survivorship was high (97%) the first two years after birth and did not differ by sex. Male and female survival began to differ by the age of 13 years, and males demonstrated significantly lower survival relative to females by the age of 20. It is suspected these differences are driven by human selection for ivory. Forest elephants were found to have one of the longest generation times recorded for any species at 31 years. These data provide fundamental understanding of forest elephant demography, providing baseline data for projecting population status and trends. PMID- 29447209 TI - Haplotype-based genome-wide association study identifies loci and candidate genes for milk yield in Holsteins. AB - Since milk yield is a highly important economic trait in dairy cattle, the genome wide association study (GWAS) is vital to explain the genetic architecture underlying milk yield and to perform marker-assisted selection (MAS). In this study, we adopted a haplotype-based empirical Bayesian GWAS to identify the loci and candidate genes for milk yield. A total of 1 092 Holstein cows were sequenced by using the genotyping by genome reducing and sequencing (GGRS) method. After filtering, 164 312 high-confidence SNPs and 13 476 haplotype blocks were identified to use for GWAS. The results indicated that 17 blocks were significantly associated with milk yield. We further identified the nearest gene of each haplotype block and annotated the genes with milk-associated quantitative trait locus (QTL) intervals and ingenuity pathway analysis (IPA) networks. Our analysis showed that four genes, DLGAP1, AP2B1, ITPR2 and THBS4, have relationships with milk yield, while another three, ARHGEF4, TDRD1 and KIF19, were inferred to have potential relationships. Additionally, a network derived from the IPA containing one inferred (ARHGEF4) and all four confirmed genes likely regulates milk yield. Our findings add to the understanding of identifying the causal genes underlying milk production traits and could guide follow up studies for further confirmation of the associated genes, pathways and biological networks. PMID- 29447208 TI - Species-specific regulation of angiogenesis by glucocorticoids reveals contrasting effects on inflammatory and angiogenic pathways. AB - Glucocorticoids are potent inhibitors of angiogenesis in the rodent in vivo and in vitro but the mechanism by which this occurs has not been determined. Administration of glucocorticoids is used to treat a number of conditions in horses but the angiogenic response of equine vessels to glucocorticoids and, therefore, the potential role of glucocorticoids in pathogenesis and treatment of equine disease, is unknown. This study addressed the hypothesis that glucocorticoids would be angiostatic both in equine and murine blood vessels.The mouse aortic ring model of angiogenesis was adapted to assess the effects of cortisol in equine vessels. Vessel rings were cultured under basal conditions or exposed to: foetal bovine serum (FBS; 3%); cortisol (600 nM), cortisol (600nM) plus FBS (3%), cortisol (600nM) plus either the glucocorticoid receptor antagonist RU486 or the mineralocorticoid receptor antagonist spironolactone. In murine aortae cortisol inhibited and FBS stimulated new vessel growth. In contrast, in equine blood vessels FBS alone had no effect but cortisol alone, or in combination with FBS, dramatically increased new vessel growth compared with controls. This effect was blocked by glucocorticoid receptor antagonism but not by mineralocorticoid antagonism. The transcriptomes of murine and equine angiogenesis demonstrated cortisol-induced down-regulation of inflammatory pathways in both species but up-regulation of pro-angiogenic pathways selectively in the horse. Genes up-regulated in the horse and down-regulated in mice were associated with the extracellular matrix. These data call into question our understanding of glucocorticoids as angiostatic in every species and may be of clinical relevance in the horse. PMID- 29447210 TI - Functional imaging of the interaction between gut microbiota and the human host: A proof-of-concept clinical study evaluating novel use for 18F-FDG PET-CT. AB - Recent data comparing germ-free to conventionally-raised mice demonstrated that energy homeostasis of colonocytes is dependent on gut microbiota through regulation of short chain fatty acids (SCFA) production and glucose utilization. We sought to evaluate 18F-FDG PET-CT as a novel technique for functional imaging of alterations in glucose metabolism as a result of the interaction between the gut microbiota and the human host. We conducted a prospective study in healthy humans that underwent 18F-FDG PET-CT and sampling of the gut microbiota before and after orally administered broad-spectrum antibiotics. The primary outcomes were total and regional physiologic colonic 18F-FDG uptake (measured as the mean and max standardized uptake values [SUVmean and SUVmax]). The study demonstrated significant increases in physiologic colonic 18F-FDG uptake in all study participants following antibiotic treatment and a 4-5log reduction of gut bacterial load. The mean increase in SUVmax was 0.63+/-0.37 SD (p = 0.004) and the median increase was 0.42 with an IQR of 0.40-0.81. The mean increase in SUVmean was 0.31+/-0.24 SD (p = 0.01) and the median increase was 0.41 with an IQR of 0.06-0.55. A likely explanation for this phenomenon is a shift in colonocyte metabolism to glycolysis due to a shortage of SCFA.

AB - AIM: Proprotein Convertase Subtilisin/Kexin Type 9 (PCSK9) is a hepatic secretory protein which promotes the degradation of low-density lipoprotein receptors leading to reduced hepatic uptake of plasma cholesterol. Non-synonymous single nucleotide polymorphisms in its gene have been linked to hypo- or hyper- cholesterolemia, depending on whether they decrease or increase PCSK9 activity, respectively. Since the proliferation and the infectivity of Plasmodium spp. partially depend on cholesterol from the host, we hypothesize that these PCSK9 genetic polymorphisms could influence the course of malaria infection in individuals who carry them. Here we examined the frequency distribution of one dominant (C679X) and two recessive (A443T, I474V) hypocholesterolemic polymorphisms as well as that of one recessive hypercholesterolemic polymorphism (E670G) among healthy and malaria-infected Malian children. METHODS: Dried blood spots were collected in Bandiagara, Mali, from 752 age, residence and ethnicity matched children: 253 healthy controls, 246 uncomplicated malaria patients and 253 severe malaria patients. Their genomic DNA was extracted and genotyped for the above PCSK9 polymorphisms using Taqman assays. Associations of genotype distributions and allele frequencies with malaria were evaluated. RESULTS: The minor allele frequency of the A443T, I474V, E670G, and C679X polymorphisms in the study population sample was 0.12, 0.20, 0.26, and 0.02, respectively. For each polymorphism, the genotype distribution among the three health conditions was statistically insignificant, but for the hypercholesterolemic E670G polymorphism, a trend towards association of the minor allele with malaria severity was observed (P = 0.035). The association proved to be stronger when allele frequencies between healthy controls and severe malaria cases were compared (Odd Ratio: 1.34; 95% Confidence Intervals: 1.04-1.83); P = 0.031). CONCLUSIONS: Carriers of the minor allele of the E670G PCSK9 polymorphism might be more susceptible to severe malaria. Further investigation of the cholesterol regulating function of PCSK9 in the pathophysiology of malaria is needed.

Here, we explore the following hypothesis: when replaying the tape, the details ("decorations") of the outcomes would vary but certain "invariants" might emerge across different life-tapes sharing similar initial conditions. We use large-scale simulations of an in silico model of pre-biotic evolution called GARD (Graded Autocatalysis Replication Domain) to test this hypothesis. GARD models the temporal evolution of molecular assemblies, governed by a rates matrix (i.e. network) that biases different molecules' likelihood of joining or leaving a dynamically growing and splitting assembly. Previous studies have shown the emergence of so called compotypes, i.e., species capable of replication and selection response. Here, we apply networks' science to ascertain the degree to which invariants emerge across different life-tapes under GARD dynamics and whether one can predict these invariant from the chemistry specification alone (i.e. GARD's rates network representing initial conditions). We analysed the (complex) rates' network communities and asked whether communities are related (and how) to the emerging species under GARD's dynamic, and found that the communities correspond to the species emerging from the simulations. Importantly, we show how to use the set of communities detected to predict species emergence without performing any simulations. The analysis developed here may impact complex systems simulations in general.

AB - Defining and identifying changes to seasonal ranges of migratory species is required for effective conservation. Historic sightings of migrating whooping cranes (Grus americana) have served as sole source of information to define a migration corridor in the Great Plains of North America (i.e., Canadian Prairies and United States Great Plains) for this endangered species. We updated this effort using past opportunistic sightings from 1942-2016 (n = 5,055) and more recent (2010-2016) location data from 58 telemetered birds (n = 4,423) to delineate migration corridors that included 50%, 75%, and 95% core areas. All migration corridors were well defined and relatively compact, with the 95% core corridor averaging 294 km wide, although it varied approximately +/-40% in width from 170 km in central Texas to 407 km at the international border of the United States and Canada. Based on historic sightings and telemetry locations, we detected easterly movements in locations over time, primarily due to locations west of the median shifting east. This shift occurred from northern Oklahoma to central Saskatchewan at an average rate of 1.2 km/year (0.3-2.8 km/year). Associated with this directional shift was a decrease in distance of locations from the median in the same region averaging -0.7 km/year (-0.3--1.3 km/year), suggesting a modest narrowing of the migration corridor. Changes in the corridor over the past 8 decades suggest that agencies and organizations interested in recovery of this species may need to modify where conservation and recovery actions occur. Whooping cranes showed apparent plasticity in their migratory behavior, which likely has been necessary for persistence of a wetland-dependent species migrating through the drought-prone Great Plains. Behavioral flexibility will be useful for whooping cranes to continue recovery in a future of uncertain climate and land use changes throughout their annual range. PMID- 29447214 TI - High efficiency classification of children with autism spectrum disorder. AB - Autism spectrum disorder (ASD) is a wide-ranging collection of developmental diseases with varying symptoms and degrees of disability. Currently, ASD is diagnosed mainly with psychometric tools, often unable to provide an early and reliable diagnosis. Recently, biochemical methods are being explored as a means to meet the latter need. For example, an increased predisposition to ASD has been associated with abnormalities of metabolites in folate-dependent one carbon metabolism (FOCM) and transsulfuration (TS). Multiple metabolites in the FOCM/TS pathways have been measured, and statistical analysis tools employed to identify certain metabolites that are closely related to ASD. The prime difficulty in such biochemical studies comes from (i) inefficient determination of which metabolites are most important and (ii) understanding how these metabolites are collectively related to ASD. This paper presents a new method based on scores produced in Support Vector Machine (SVM) modeling combined with High Dimensional Model Representation (HDMR) sensitivity analysis. The new method effectively and efficiently identifies the key causative metabolites in FOCM/TS pathways, ranks their importance, and discovers their independent and correlative action patterns upon ASD. Such information is valuable not only for providing a foundation for a pathological interpretation but also for potentially providing an early, reliable diagnosis ideally leading to a subsequent comprehensive treatment of ASD. With only tens of SVM model runs, the new method can identify the combinations of the most important metabolites in the FOCM/TS pathways that lead to ASD. Previous efforts to find these metabolites required hundreds of thousands of model runs with the same data. PMID- 29447215 TI - Maternal high-fat diet associated with altered gene expression, DNA methylation, and obesity risk in mouse offspring. AB - We investigated maternal obesity in inbred SM/J mice by assigning females to a high-fat diet or a low-fat diet at weaning, mating them to low-fat-fed males, cross-fostering the offspring to low-fat-fed SM/J nurses at birth, and weaning the offspring onto a high-fat or low-fat diet. A maternal high-fat diet exacerbated obesity in the high-fat-fed daughters, causing them to weigh more, have more fat, and have higher serum levels of leptin as adults, accompanied by dozens of gene expression changes and thousands of DNA methylation changes in their livers and hearts. Maternal diet particularly affected genes involved in RNA processing, immune response, and mitochondria. Between one-quarter and one third of differentially expressed genes contained a differentially methylated region associated with maternal diet. An offspring high-fat diet reduced overall variation in DNA methylation, increased body weight and organ weights, increased long bone lengths and weights, decreased insulin sensitivity, and changed the expression of 3,908 genes in the liver. Although the offspring were more affected by their own diet, their maternal diet had epigenetic effects lasting through adulthood, and in the daughters these effects were accompanied by phenotypic changes relevant to obesity and diabetes. PMID- 29447216 TI - Genome mining of Streptomyces scabrisporus NF3 reveals symbiotic features including genes related to plant interactions. AB - Endophytic bacteria are wide-spread and associated with plant physiological benefits, yet their genomes and secondary metabolites remain largely unidentified. In this study, we explored the genome of the endophyte Streptomyces scabrisporus NF3 for discovery of potential novel molecules as well as genes and metabolites involved in host interactions. The complete genomes of seven Streptomyces and three other more distantly related bacteria were used to define the functional landscape of this unique microbe. The S. scabrisporus NF3 genome is larger than the average Streptomyces genome and not structured for an obligate endosymbiotic lifestyle; this and the fact that can grow in R2YE media implies that it could include a soil-living stage. The genome displays an enrichment of genes associated with amino acid production, protein secretion, secondary metabolite and antioxidants production and xenobiotic degradation, indicating that S. scabrisporus NF3 could contribute to the metabolic enrichment of soil microbial communities and of its hosts. Importantly, besides its metabolic advantages, the genome showed evidence for differential functional specificity and diversification of plant interaction molecules, including genes for the production of plant hormones, stress resistance molecules, chitinases, antibiotics and siderophores. Given the diversity of S. scabrisporus mechanisms for host upkeep, we propose that these strategies were necessary for its adaptation to plant hosts and to face changes in environmental conditions. PMID- 29447218 TI - FindPrimaryPairs: An efficient algorithm for predicting element-transferring reactant/product pairs in metabolic networks. AB - The metabolism of individual organisms and biological communities can be viewed as a network of metabolites connected to each other through chemical reactions. In metabolic networks, chemical reactions transform reactants into products, thereby transferring elements between these metabolites. Knowledge of how elements are transferred through reactant/product pairs allows for the identification of primary compound connections through a metabolic network. However, such information is not readily available and is often challenging to obtain for large reaction databases or genome-scale metabolic models. In this study, a new algorithm was developed for automatically predicting the element transferring reactant/product pairs using the limited information available in the standard representation of metabolic networks. The algorithm demonstrated high efficiency in analyzing large datasets and provided accurate predictions when benchmarked with manually curated data. Applying the algorithm to the visualization of metabolic networks highlighted pathways of primary reactant/product connections and provided an organized view of element transferring biochemical transformations. The algorithm was implemented as a new function in the open source software package PSAMM in the release v0.30 (https://zhanglab.github.io/psamm/). PMID- 29447217 TI - Does napping enhance the effects of Cognitive Bias Modification-Appraisal training? An experimental study. AB - Posttraumatic Stress Disorder (PTSD) is characterised by dysfunctional appraisals of the trauma and its consequences including one's own symptoms. Experimental studies have shown that Cognitive Bias Modification-Appraisal (CBM-App) training can reduce dysfunctional interpretations and analog trauma symptoms. One important question is how to enhance the effects of CBM-App. Following work suggesting that sleep has beneficial effects on consolidation processes and can thus improve learning, the present study investigated whether a brief period of sleep (i.e., a nap) enhances the effects of CBM-App. All participants watched a stressful movie as an analogue trauma induction. After that, participants received either positive or negative CBM-App training. Within each training, half of the participants then had a 90-minute nap or watched a neutral movie. Results showed that the CBM training induced training-congruent appraisals. Sleep did not enhance this effect. Participants who slept, however, experienced fewer intrusive memories of the analogue trauma, but this effect was independent of the CBM condition. These results provide valuable information about the effects of sleep during a 90-minute nap period on encoding of analogue trauma and emotional learning in the context of appraisal, and highlight the importance of sleep as a focus for continued research. PMID- 29447219 TI - Optimization of prophylaxis for hemophilia A. AB - BACKGROUND & AIMS: Prophylactic injections of factor VIII reduce the incidence of bleeds and slow the development of joint damage in people with hemophilia. The aim of this study was to identify optimal person-specific prophylaxis regimens for children with hemophilia A. METHODS: Analytic and numerical methods were used to identify prophylaxis regimens which maximize the time for which plasma factor VIII concentrations exceed a threshold, maximize the lowest plasma factor VIII concentrations, and minimize risk of bleeds. RESULTS: It was demonstrated analytically that, for any injection schedule, the regimen that maximizes the lowest factor VIII concentration involves sharing doses between injections so that all of the trough concentrations in a prophylaxis cycle are equal. Numerical methods were used to identify optimal prophylaxis schedules and explore the trade offs between efficacy and acceptability of different prophylaxis regimens. The prophylaxis regimen which minimizes risk of bleeds depends on the person's pattern of physical activity and may differ greatly from prophylaxis regimens that optimize pharmacokinetic parameters. Prophylaxis regimens which minimize risk of bleeds also differ from prophylaxis regimens that are typically prescribed. Predictions about which regimen is optimal are sensitive to estimates of the effects on risk of bleeds of factor VIII concentration and physical activity. CONCLUSION: The methods described here can be used to identify optimal, person-specific prophylaxis regimens for children with hemophilia A. PMID- 29447220 TI - The relationship between context, structure, and processes with outcomes of 6 regional diabetes networks in Europe. AB - BACKGROUND: While health service provisioning for the chronic condition Type 2 Diabetes (T2D) often involves a network of organisations and professionals, most evidence on the relationships between the structures and processes of service provisioning and the outcomes considers single organisations or solo practitioners. Extending Donabedian's Structure-Process-Outcome (SPO) model, we investigate how differences in quality of life, effective coverage of diabetes, and service satisfaction are associated with differences in the structures, processes, and context of T2D services in six regions in Finland, Germany, Greece, Netherlands, Spain, and UK. METHODS: Data collection consisted of: a) systematic modelling of provider network's structures and processes, and b) a cross-sectional survey of patient reported outcomes and other information. The survey resulted in data from 1459 T2D patients, during 2011-2012. Stepwise linear regression models were used to identify how independent cumulative proportion of variance in quality of life and service satisfaction are related to differences in context, structure and process. The selected context, structure and process variables are based on Donabedian's SPO model, a service quality research instrument (SERVQUAL), and previous organization and professional level evidence. Additional analysis deepens the possible bidirectional relation between outcomes and processes. RESULTS: The regression models explain 44% of variance in service satisfaction, mostly by structure and process variables (such as human resource use and the SERVQUAL dimensions). The models explained 23% of variance in quality of life between the networks, much of which is related to contextual variables. Our results suggest that effectiveness of A1c control is negatively correlated with process variables such as total hours of care provided per year and cost of services per year. CONCLUSIONS: While the selected structure and process variables explain much of the variance in service satisfaction, this is less the case for quality of life. Moreover, it appears that the effect of the clinical outcome A1c control on processes is stronger than the other way around, as poorer control seems to relate to more service use, and higher cost. The standardized operational models used in this research prove to form a basis for expanding the network level evidence base for effective T2D service provisioning. PMID- 29447221 TI - How does the interaction radius affect the performance of intervention on collective behavior? AB - The interaction radius r plays an important role in the collective behavior of many multi-agent systems because it defines the interaction network among agents. For the topic of intervention on collective behavior of multi-agent systems, does r also affect the intervention performance? In this paper we study whether it is easier to change the convergent heading of the group by adding some special agents (called shills) into the Vicsek model when r is larger (or smaller). Two kinds of shills are considered: fixed-heading shills (like leaders that never change their headings) and evolvable-heading shills (like normal agents but with carefully designed initial headings). We know that with the increase of r, two contradictory effects exist simultaneously: the influential area of a single shill is enlarged, but its influence strength is weakened. Which factor dominates? Through simulations and theoretical analysis we surprisingly find that r affects the intervention performance differently in different cases: when fixed heading shills are placed together at the center of the group, larger r gives a better intervention performance; when evolvable-heading shills are placed together at the center, smaller r is better; when shills (either fixed-heading or evolvable-heading) are distributed evenly inside the group, the effect of r on the intervention performance is not significant. We believe these results will inspire the design of intervention strategies for many other multi-agent systems. PMID- 29447222 TI - Kinetics of PTEN-mediated PI(3,4,5)P3 hydrolysis on solid supported membranes. AB - Phosphatidylinositides play important roles in cellular signaling and migration. Phosphatidylinositol-3,4,5-trisphosphate (PI(3,4,5)P3) is an important phosphatidylinositide because it acts as a secondary messenger to trigger cell movement and proliferation. A high level of PI(3,4,5)P3 at the plasma membrane is known to contribute to tumorigenesis. One key enzyme that regulates PI(3,4,5)P3 levels at the plasma membrane is phosphatase and tensin homologue deleted on chromosome 10 (PTEN), which dephosphorylates PI(3,4,5)P3 through hydrolysis to form phosphatidylinositol-4,5-bisphosphate (PI(4,5)P2). It has been reported that PI(4,5)P2 is involved in positive feedback in the PI(3,4,5)P3 hydrolysis by PTEN. However, how PI(3,4,5)P3 dephosphorylation by PTEN is regulated, is still under debate. How other PI(3,4,5)P3-binding proteins affect the dephosphorylation kinetics catalyzed by PTEN also remains unclear. Here, we develop a fluorescent protein biosensor approach to study how PI(3,4,5)P3 dephosphorylation is regulated by PTEN as well as its membrane-mediated feedback mechanisms. Our observation of sigmoidal kinetics of the PI(3,4,5)P3 hydrolysis reaction supports the notion of autocatalysis in PTEN function. We developed a kinetic model to describe the observed reaction kinetics, which allowed us to i) distinguish between membrane-recruitment and allosteric activation of PTEN by PI(4,5)P2, ii) account for the influence of the biosensor on the observed reaction kinetics, and iii) demonstrate that all of these mechanisms contribute to the kinetics of PTEN mediated catalysis. PMID- 29447223 TI - Virome and bacteriome characterization of children with pneumonia and asthma in Mexico City during winter seasons 2014 and 2015. AB - BACKGROUND: Acute asthma exacerbations and pneumonia are important causes of morbidity and mortality in children and may coexist in the same children, although symptom overlap may lead to difficulties in diagnosis. Microbial and viral diversity and differential abundance of either may play an important role in infection susceptibility and the development of acute and chronic respiratory diseases. OBJECTIVES: To describe the virome and bacteriome present in the upper respiratory tract of hospitalized children with a clinical diagnosis of asthma and pneumonia during an acute exacerbation and an acute respiratory illness ARI episode respectively. METHODS: During the winter seasons of 2013-2014 and 2014 2015, 134 nasopharyngeal swabs samples of children <15 years of age with ARI hospitalized at a referral hospital for respiratory diseases were selected based on clinical diagnosis of asthma or pneumonia. The virome and bacteriome were characterized using Whole Genome Sequencing (WGS) and in-house bioinformatics analysis pipeline. RESULTS: The Asthma group was represented mainly by RV-C, BoV 1 and RSV-B and the pneumonia group by Bacteriophage EJ-1 and TTMV. TTV was found in both groups with a similar amount of reads. About bacterial composition Moraxella catarrhalis, Propionibacterium acnes and Acinetobacter were present in asthma and Veillonella parvula and Mycoplasma pneumoniae in pneumonia. Streptococcus pneumoniae and Haemophilus influenzae were mostly found with both asthma and pneumonia. CONCLUSIONS: Our results show a complex viral and bacterial composition in asthma and pneumonia groups with a strong association of RV-C presence in asthmatic children. We observed Streptococcus pneumoniae and Haemophilus influenzae concurrently in both groups. PMID- 29447224 TI - Directional freezing for the cryopreservation of adherent mammalian cells on a substrate. AB - Successfully cryopreserving cells adhered to a substrate would facilitate the growth of a vital confluent cell culture after thawing while dramatically shortening the post-thaw culturing time. Herein we propose a controlled slow cooling method combining initial directional freezing followed by gradual cooling down to -80 degrees C for robust preservation of cell monolayers adherent to a substrate. Using computer controlled cryostages we examined the effect of cooling rates and dimethylsulfoxide (DMSO) concentration on cell survival and established an optimal cryopreservation protocol. Experimental results show the highest post thawing viability for directional ice growth at a speed of 30 MUm/sec (equivalent to freezing rate of 3.8 degrees C/min), followed by gradual cooling of the sample with decreasing rate of 0.5 degrees C/min. Efficient cryopreservation of three widely used epithelial cell lines: IEC-18, HeLa, and Caco-2, provides proof-of concept support for this new freezing protocol applied to adherent cells. This method is highly reproducible, significantly increases the post-thaw cell viability and can be readily applied for cryopreservation of cellular cultures in microfluidic devices. PMID- 29447225 TI - Low apolipoprotein A-I levels in Friedreich's ataxia and in frataxin-deficient cells: Implications for therapy. AB - Friedreich's ataxia (FA) is an autosomal recessive neurodegenerative disorder, which results primarily from reduced expression of the mitochondrial protein frataxin. FA has an estimated prevalence of one in 50,000 in the population, making it the most common hereditary ataxia. Paradoxically, mortality arises most frequently from cardiomyopathy and cardiac failure rather than from neurological effects. Decreased high-density lipoprotein (HDL) and apolipoprotein A-I (ApoA-l) levels in the general population are associated with an increased risk of mortality from cardiomyopathy and heart failure. However, the pathophysiology of heart disease in FA is non-vascular and there are conflicting data on HDL cholesterol in FA. Two studies have shown a decrease in HDL-cholesterol compared with controls and two have shown there was no difference between FA and controls. One also showed that there was no difference in serum Apo-A-I levels in FA when compared with controls. Using a highly specific stable isotope dilution mass spectrometry-based assay, we demonstrated a 21.6% decrease in serum ApoA-I in FA patients (134.8 mg/dL, n = 95) compared with non-affected controls (172.1 mg/dL, n = 95). This is similar to the difference in serum ApoA-I levels between non smokers and tobacco smokers. Knockdown of frataxin by > 70% in human hepatoma HepG2 cells caused a 20% reduction in secreted ApoA-I. Simvastatin, a 3-hydroxy-3 methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitor caused a 200% increase in HMG-CoA in the control HepG2 cells with a similar increase in the frataxin knockdown HepG2 cells, back to levels found in the control cells. There was a concomitant 20% increase in secreted ApoA-I to levels found in the control cells that were treated with simvastatin. This study provides compelling evidence that ApoA-I levels are reduced in FA patients compared with controls and suggest that statin treatment would normalize the ApoA-I levels. PMID- 29447226 TI - Barriers and facilitators to antiretroviral therapy adherence among Peruvian adolescents living with HIV: A qualitative study. AB - AIDS deaths among adolescents are increasing globally. This qualitative study investigated the barriers and facilitators to cART adherence among Peruvian adolescents living with HIV. Guided by a social ecological model, we analyzed transcripts from 24 psychosocial support groups for HIV-positive adolescents aged 13-17 years and 15 individual, in-depth interviews with cART providers and caregivers to identify the barriers and facilitators to cART adherence at the individual, family/caregiver and hospital levels. Most barriers and facilitators to cART adherence clustered at the individual and family/caregiver levels, centering on support provided to adolescents; history of declining health due to suboptimal cART adherence; side effects from antiretroviral drugs; and cART misinformation. Interventions to support adolescent HIV cART adherence should begin at the individual and family/caregiver levels and include an educational component. No adolescent living with HIV should die from AIDS in an era of accessible cART. PMID- 29447227 TI - Probiotic effect of Pichia pastoris X-33 produced in parboiled rice effluent and YPD medium on broiler chickens. AB - In a previous paper we showed that the yeast Pichia pastoris X-33 grown in parboiled rice effluent supplemented with glycerol byproduct from the biodiesel industry improved the quality of the effluent. In this paper we show the validation of this yeast (PPE) as probiotic for broilers. Its effect on feed efficiency and immunomodulation was compared with the same yeast grown in yeast peptone dextrose medium (PPY), with Saccharomyces boulardii (SBY) and with the controls fed unsupplemented feed (CON). One-day-old female chicks were vaccinated against infectious bursal disease (IBD) and the titers of anti-IBD antibodies were measured by ELISA. PPE group had the highest mean titres on days 14 and 28 (p<0,05), and at 28 days, 64% of the animals showed seroconvertion. The PPE group also showed the best weight gains at 42 days of age, that, on days 7, 14 and 21 were 19%, 15%, and 8.7% higher, respectively, than the control group. The best feed conversion, 8.2% higher than the control group, was obtained by PPY at 42 days. Histopathological studies did not detect any undesirable effects in the supplemented animals. We concluded that Pichia pastoris X-33 when grown in effluents of the rice parboiling industry supplemented with glycerol byproduct from the biodiesel has probiotic properties for poultry. PMID- 29447228 TI - Chromosomal distribution of pTa-535, pTa-86, pTa-713, 35S rDNA repetitive sequences in interspecific hexaploid hybrids of common wheat (Triticum aestivum L.) and spelt (Triticum spelta L.). AB - Fluorescent in situ hybridization (FISH) relies on fluorescent-labeled probes to detect specific DNA sequences in the genome, and it is widely used in cytogenetic analyses. The aim of this study was to determine the karyotype of T. aestivum and T. spelta hybrids and their parental components (three common wheat cultivars and five spelt breeding lines), to identify chromosomal aberrations in the evaluated wheat lines, and to analyze the distribution of polymorphisms of repetitive sequences in the examined hybrids. The FISH procedure was carried out with four DNA clones, pTa-86, pTa-535, pTa-713 and 35S rDNA used as probes. The observed polymorphisms between the investigated lines of common wheat, spelt and their hybrids was relatively low. However, differences were observed in the distribution of repetitive sequences on chromosomes 4A, 6A, 1B and 6B in selected hybrid genomes. The polymorphisms observed in common wheat and spelt hybrids carry valuable information for wheat breeders. The results of our study are also a valuable source of knowledge about genome organization and diversification in common wheat, spelt and their hybrids. The relevant information is essential for common wheat breeders, and it can contribute to breeding programs aimed at biodiversity preservation. PMID- 29447229 TI - HIV epidemics in Shenzhen and Chongqing, China. AB - OBJECTIVE: Men who have sex with men (MSM) and heterosexuals are the populations with the fastest growing HIV infection rates in China. We characterize the epidemic growth and age patterns between these two routes from 2004 to 2015 in Chongqing and Shenzhen, China. DESIGN AND METHODS: Data were downloaded from the National HIV/ AIDS Comprehensive Response Information Management System. For the new HIV diagnoses of heterosexuals and MSM in both cities, we estimated the growth rates by fitting different sub-exponential models. Heat maps are used to show their age patterns. We used histograms to compare these patterns by birth cohort. RESULTS: The MSM epidemics grew significantly in both cities. Chongqing experienced quadratic growth in HIV reported cases with an estimated growth rate of 0.086 per week and a "deceleration rate" of 0.673. HIV reported cases of MSM in Shenzhen grew even more drastically with a growth rate of 0.033 per week and "deceleration rate" of 0.794. The new infections are mainly affecting the ages of 18 to 30 in Chongqing and ages of 20 to 35 in Shenzhen. They peaked in early 1990's and mid-1990's birth cohorts in Chongqing and Shenzhen respectively. The HIV epidemic among heterosexuals grew rapidly in both cities. The growth rates were estimated as 0.02 and 0.028 in Chongqing and Shenzhen respectively whereas the "deceleration rates" were 0.878 and 0.790 in these two places. It affected mostly aged 18 to 75 in males and 18 to 65 in females in Chongqing and aged 18 to 45 in males and 18 to 50 in females in Shenzhen in 2015. In Chongqing, the heterosexual female epidemics display two peaks in HIV diagnoses in the birth cohorts of early 1950's and early 1980's, with heterosexual male epidemics peaked in early 1940's and early 1960's. The heterosexual male and female epidemics display higher rates in the birth cohort 1940-1960, than the birth cohort 1960 1990. It peaked in birth cohorts of 1950's and 1980's in Shenzhen. CONCLUSIONS: We revealed striking differences in epidemic growth and age patterns of the HIV epidemics in these two cities. Our results may be used to inform age-targeted public health policies to curb their epidemic growth. PMID- 29447231 TI - Preparedness of lower-level health facilities and the associated factors for the outpatient primary care of hypertension: Evidence from Tanzanian national survey. AB - INTRODUCTION: Sub-Saharan Africa is experiencing a rapid rise in the burden of non-communicable diseases in both urban and rural areas. Data on health system preparedness to manage hypertension and other non-communicable diseases remains scarce. This study aimed to assess the preparedness of lower-level health facilities for outpatient primary care of hypertension in Tanzania. METHODS: This study used data from the 2014-2015 Tanzania Service Provision Assessment survey. The facility was considered as prepared for the outpatient primary care of hypertension if reported at least half (>=50%) of the items listed from each of the three domains (staff training and guideline, basic diagnostic equipment, and basic medicines) as identified by World Health Organization-Service Availability and Readiness Assessment manual. Data were analyzed using Stata 14. An unadjusted logistic regression model was used to assess the association between outcome and explanatory variables. All variables with a P value < 0.2 were fitted into the multiple logistic regression models using a 5% significance level. RESULTS: Out of 725 health facilities involved in the current study, about 68% were public facilities and 73% located in rural settings. Only 28% of the assessed facilities were considered prepared for the outpatient primary care of hypertension. About 9% and 42% of the assessed facilities reported to have at least one trained staff and guidelines for hypertension respectively. In multivariate analysis, private facilities [AOR = 2.7, 95% CI; 1.2-6.1], urban location [AOR = 2.2, 95% CI; 1.2 4.2], health centers [AOR = 5.2, 95% CI; 3.1-8.7] and the performance of routine management meetings [AOR = 2.6, 95% CI; 1.1-5.9] were significantly associated with preparedness for the outpatient primary care of hypertension. CONCLUSION: The primary healthcare system in Tanzania is not adequately equipped to cope with the increasing burden of hypertension and other non-communicable diseases. Rural location, public ownership, and absence of routine management meetings were associated with being not prepared. There is a need to strengthen the primary healthcare system in Tanzania for better management of chronic diseases and curb their rising impact on health outcomes. PMID- 29447230 TI - Propofol induces a metabolic switch to glycolysis and cell death in a mitochondrial electron transport chain-dependent manner. AB - The intravenous anesthetic propofol (2,6-diisopropylphenol) has been used for the induction and maintenance of anesthesia and sedation in critical patient care. However, the rare but severe complication propofol infusion syndrome (PRIS) can occur, especially in patients receiving high doses of propofol for prolonged periods. In vivo and in vitro evidence suggests that the propofol toxicity is related to the impaired mitochondrial function. However, underlying molecular mechanisms remain unknown. Therefore, we investigated effects of propofol on cell metabolism and death using a series of established cell lines of various origins, including neurons, myocytes, and trans-mitochondrial cybrids, with defined mitochondrial DNA deficits. We demonstrated that supraclinical concentrations of propofol in not less than 50 MUM disturbed the mitochondrial function and induced a metabolic switch, from oxidative phosphorylation to glycolysis, by targeting mitochondrial complexes I, II and III. This disturbance in mitochondrial electron transport caused the generation of reactive oxygen species, resulting in apoptosis. We also found that a predisposition to mitochondrial dysfunction, caused by a genetic mutation or pharmacological suppression of the electron transport chain by biguanides such as metformin and phenformin, promoted propofol induced caspase activation and cell death induced by clinical relevant concentrations of propofol in not more than 25 MUM. With further experiments with appropriate in vivo model, it is possible that the processes to constitute the molecular basis of PRIS are identified.

AB - Hepatitis B virus (HBV) diversity has not been previously studied in Cape Verde. The archipelago was discovered in 1460 by Portuguese explorers, who brought African slaves to colonise the islands. In this study, we investigated the HBV characteristics from 183 HBsAg-positive Cape Verdean individuals. Phylogenetic analysis of the pre-S/S region and the full-length genomes revealed 54 isolates with HBV/A1 (57%), 21 with HBV/A2 (22%), 19 with HBV/E (20%), and one with HBV/D (1%). HBV genotypes and subgenotypes were unequally distributed through the islands. In Sao Vicente, the main northern island, most isolates (84%) belonged to the African-originated HBV/A1, with the remaining isolates belonging to HBV/A2, which is prevalent in Europe. Interestingly, the HBV/A1 isolates from Sao Vicente were closely related to Brazilian sequences into the Asian-American clade, which suggests the dissemination of common African ancestors through slave trade. In contrast, in Santiago and nearby southern islands, where a recent influx from different populations circulates, a higher diversity of HBV was observed: HBV/A1 (40%); HBV/E (32%); HBV/A2 (28%); and HBV/D (1%). HBV/E is a recent genotype disseminated in Africa that was absent in the era of the slave trade. African and European human flows at different times of the history may explain the HBV diversity in Cape Verde. The possible origin and specifics of each HBV genotype circulating in Cape Verde are discussed.

The gamma-secretase inhibitor DAPT inhibits Notch signaling pathway and promotes nerve regeneration after cerebral ischemia. However, neuroprotective effects of DAPT against acute craniocerebral injury remain unclear. In this study, we established rat model of acute craniocerebral injury, and found that with the increase of damage grade, the expression of Notch and downstream protein Hes1 and Hes5 expression gradually increased. After the administration of DAPT, the expression of Notch, Hes1 and Hes5 was inhibited, apoptosis and oxidative stress decreased, neurological function and cognitive function improved. These results suggest that Notch signaling can be used as an indicator to assess the severity of post-traumatic brain injury. Notch inhibitor DAPT can reduce oxidative stress and apoptosis after acute craniocerebral injury, and is a potential drug for the treatment of acute craniocerebral injury. PMID- 29447235 TI - The dominance of introspective measures and what this implies: The example of environmental attitude. AB - The behavioral sciences, including most of psychology, seek to explain and predict behavior with the help of theories and models that involve concepts (e.g., attitudes) that are subsequently translated into measures. Currently, some subdisciplines such as social psychology focus almost exclusively on measures that demand reflection or even introspection when administered to persons. We argue that such a focus hinders progress in explaining behavior. One major reason is that such an exclusive focus on reflections results in common method bias, which then produces spurious relations, or in other words, low discriminant validity. Without the valid measurement of theoretical concepts, theoretical assumptions cannot be tested, and hence, theory development will be hampered. We argue that the use of a greater variety of methods would reduce these problems and would in turn foster theory building. Using a representative sample of N = 472 participants (age: M = 51.0, SD = 17.7; 54% female), we compared the validity of a classical introspective attitude measure (i.e., the New Ecological Paradigm) with that of an alternative attitude measure (i.e., the General Ecological Behavior scale). The latter measure, which was based on self-reported behavior, showed substantially better validity that we argue could aid theory development. PMID- 29447234 TI - Folic acid derived-P5779 mimetics regulate DAMP-mediated inflammation through disruption of HMGB1:TLR4:MD-2 axes. AB - High mobility group box 1 (HMGB1) is a damage-associated molecular pattern (DAMP) protein that mediates inflammatory responses after infection or injury. Previously, we reported a peptide inhibitor of HMGB1 (P5779) that acts by directly interrupting HMGB1/MD-2 binding. Here, fingerprint similarity search and docking studies suggest folic acid derived-drugs function as P5779 mimetopes. Molecular dynamic (MD) simulation studies demonstrate that folic acid mimics the binding of P5779 at the TLR4 and MD-2 intersection. In surface plasmon resonance (SPR) studies, these drugs showed direct binding to TLR4/MD-2 but not HMGB1. Furthermore, these P5779 mimetopes inhibit HMGB1 and MD-2 binding and suppress HMGB1-induced TNF release in human macrophages in the nanomolar range. We assert from our findings that their demonstrated anti-inflammatory effects may be working through TLR4-dependent signaling. PMID- 29447236 TI - The influence of a change in the meniscus cross-sectional shape on the medio lateral translation of the knee joint and meniscal extrusion. AB - OBJECTIVE: The purpose of this study was to evaluate the influence of a change in the meniscus cross sectional shape on its position and on the biomechanics of a knee joint. METHODS: One main finite element model of a left knee joint was created on the basis of MRI images. The model consisted of bones, articular cartilages, menisci and ligaments. Eight variants of this model with an increased or decreased meniscus height were then prepared. Nonlinear static analyses with a fixed flexion/extension movement for a compressive load of 1000 N were performed. The additional analyses for those models with a constrained medio-lateral relative bone translation allowed for an evaluation of the influence of this translation on a meniscus external shift. RESULTS: It was observed that a decrease in the meniscus height caused a decrease in the contact area, together with a decrease in the contact force between the flattened meniscus and the cartilage. For the models with an increased meniscus height, a maximal value of force acting on the meniscus in a medio-lateral direction was obtained. The results have shown that the meniscus external shift was approximately proportional to the meniscus slope angle, but that relationship was modified by a medio-lateral relative bone translation. It was found that the translation of the femur relative to the tibia may be dependent on the geometry of the menisci. CONCLUSIONS: The results have suggested that a change in the meniscus geometry in the cross sectional plane can considerably affect not only the meniscal external shift, but also the medio-lateral translation of the knee joint as well as the congruency of the knee joint. PMID- 29447238 TI - Ex situ cultivation protocol for Cystoseira amentacea var. stricta (Fucales, Phaeophyceae) from a restoration perspective. AB - Due to multiple impacts, Cystoseira forests are experiencing a significant decline, which is affecting the ecosystem services they provide. Despite conservation efforts, there is an urgent need to develop best practices and large scale restoration strategies. To implement restoration actions, we developed an ex situ protocol for the cultivation of Cystoseira. amentacea var. stricta, aimed at reducing the time needed for laboratory culture, thus avoiding prolonged maintenance and minimizing costs. Specifically, we tested the effects of temperature, light and substratum on settlement and growth of early life stages using a factorial experiment. Temperature (20 and 24 degrees C) and photoperiod (15L:9D) were selected to reflect the conditions experienced in the field during the reproductive period. Two light intensities (125 and 250 MUmol photons m-2s-1) were selected to mimic the condition experienced in the absence of canopy (i.e. barren-higher light intensity) or in the understory (lower light intensity) during gamete release. The tested substrata were flat polished pebbles and rough clay tiles. The release of gametes and the successive survival and development of embryo and germlings were followed for two weeks. Regardless of the culture conditions, rougher tiles showed higher zygote settlement, but the substrata did not affect the successive development. Zygote mortality after one week averaged 50% and at the end of the second week, embryonic survival was higher under lower light and temperature conditions, which also determined the growth of larger embryos. PMID- 29447237 TI - Pathophysiological and neurobehavioral characteristics of a propionic acid mediated autism-like rat model. AB - Autism spectrum disorder (ASD) is induced by complex hereditary and environmental factors. However, the mechanisms of ASD development are poorly understood. The purpose of this study was to identify standard indicators of this condition by comparing clinical, pathophysiological, and neurobehavioral features in an autism like animal model. A total of 22 male Sprague-Dawley rats were randomly divided into control and 500 mg/kg propionic acid (PPA)-treated groups. Rats were subjected to behavioral tests, gene expression analyses, and histological analyses to detect pathophysiological and neurobehavioral alterations. Exploratory activity and non-aggressive behavior were significantly reduced in PPA-treated rats, whereas enhanced aggressive behavior during adjacent interactions was observed on day 14 after PPA administration. To evaluate gene expression after PPA administration, we analyzed hippocampal tissue using reverse transcription PCR. Glial fibrillary acidic protein was augmented in the PPA treated group on day 14 after appearance of ASD-like behaviors by PPA administration, whereas octamer-binding transcription factor 4 expression was significantly decreased in the PPA-treated group. Histological evaluation revealed significantly reduced diameter and layer thickness of granule cells in PPA-treated rats compared with control rats. We conclude that PPA administration induced abnormal neural cell organization, which may have led to autism-like neurobehaviors, including increased aggressive behavior, reduced exploratory activity, and isolative and passive behaviors. PMID- 29447239 TI - Coaxial technique-promoted diagnostic accuracy of CT-guided percutaneous cutting needle biopsy for small and deep lung lesions. AB - Coaxial technique is extensively applied to facilitate percutaneous lung lesion biopsy. However, the impact of coaxial technique on diagnostic accuracy remains undecided. We reviewed 485 patients who underwent percutaneous CT-guided needle biopsies of lung lesions in our hospital. All of these biopsies were performed using either a cutting needle alone (n = 268) or a cutting needle combined with a coaxial needle (n = 217). The diagnostic accuracy and complications resulting from the two techniques were then compared. The diagnostic accuracies of the two techniques were comparably high, at 98.2% (with coaxial technique) and 95.9% (without coaxial technique), p = 0.24. Subgroup analysis discovered that for patients with lesions measuring < 1.5 cm and needle path length >= 4 cm, the coaxial technique achieved a higher diagnostic accuracy (95.5% vs. 72.7%, p = 0.023). The biopsy was well tolerated in all of the patients. Pneumothorax occurred less often in patients who were biopsied with the coaxial technique (19 versus 43, p = 0.024). Thus, the application of the coaxial technique could improve diagnostic accuracy in patients with small and deep lung lesions, and could reduce the risk of pneumothorax. The combined use of cutting needles with coaxial needles is the preferred technique for performing percutaneous CT-guided lung biopsies. PMID- 29447240 TI - B cell subset distribution is altered in patients with severe periodontitis. AB - Several studies have recently highlighted the implication of B cells in physiopathogenesis of periodontal disease by showing that a B cell deficiency leads to improved periodontal parameters. However, the detailed profiles of circulating B cell subsets have not yet been investigated in patients with severe periodontitis (SP). We hypothesised that an abnormal distribution of B cell subsets could be detected in the blood of patients with severe periodontal lesions, as already reported for patients with chronic inflammatory diseases as systemic autoimmune diseases. Fifteen subjects with SP and 13 subjects without periodontitis, according to the definition proposed by the CDC periodontal disease surveillance work group, were enrolled in this pilot observational study. Two flow cytometry panels were designed to analyse the circulating B and B1 cell subset distribution in association with the RANKL expression. A significantly higher percentage of CD27+ memory B cells was observed in patients with SP. Among these CD27+ B cells, the proportion of the switched memory subset was significantly higher. At the same time, human B1 cells, which were previously associated with a regulatory function (CD20+CD69-CD43+CD27+CD11b+), decreased in SP patients. The RANKL expression increased in every B cell subset from the SP patients and was significantly greater in activated B cells than in the subjects without periodontitis. These preliminary results demonstrate the altered distribution of B cells in the context of severe periodontitis. Further investigations with a larger cohort of patients can elucidate if the analysis of the B cell compartment distribution can reflect the periodontal disease activity and be a reliable marker for its prognosis (clinical trial registration number: NCT02833285, B cell functions in periodontitis). PMID- 29447241 TI - Selective targeting of tumor associated macrophages in different tumor models. AB - Tumor progression largely depends on the presence of alternatively polarized (M2) tumor-associated macrophages (TAMs), whereas the classical M1-polarized macrophages can promote anti-tumorigenic immune responses. Thus, selective inhibition of M2-TAMs is a desirable anti-cancer approach in highly resistant tumor entities such as hepatocellular carcinoma (HCC) or breast cancer. We here examined whether a peptide that selectively binds to and is internalized by in vitro-differentiated murine M2 macrophages as compared to M1 macrophages, termed M2pep, could be used to selectively target TAMs in HCC and breast carcinoma. We confirmed selectivity of M2pep for in vitro M2 polarized macrophages. Upon incubation of suspended mixed 4T1 tumor cells with M2pep, high amounts of the TAMs were found to be associated with M2pep, whereas in mixed tumor cell suspensions from two HCC mouse models, M2pep showed only low-degree binding to TAMs. M2pep also showed low-degree targeting of liver macrophages. This indicates that the TAMs in different tumor entities show different targeting of M2pep and that M2pep is a very promising approach to develop selective M2-TAM-targeting in tumor entities containing M2-TAMs with significant amounts of the so far elusive M2pep receptor(s). PMID- 29447242 TI - A novel ligand on astrocytes interacts with natural cytotoxicity receptor NKp44 regulating immune response mediated by NK cells. AB - NK cells play important role in immunity against pathogens and cancer. NK cell functions are regulated by inhibitory and activating receptors binding corresponding ligands on the surface of target cells. NK cells were shown to be recruited to the CNS following several pathological conditions. NK cells could impact CNS physiology by killing glial cells and by secreting IFN-gamma. Astrocytes are intimately involved in immunological and inflammatory events occurring in the CNS and reactive astrogliosis is a key feature in HIV-associated neurocognitive disorders. There is little data on NK-astrocyte interactions and ligands expressed on astrocytes that could impact NK cell function. Natural cytotoxicity receptors (NCRs) play a critical role in the cytolytic function of NK cells. Among the NCRs, NKp44 is unique in expression and signal transduction. NKp44 is expressed only upon activation of NK cells and it can mediate both activating and inhibitory signals to NK cells. Here, we have studied the expression and function of natural cytotoxicity receptor NKp44 upon NK-astrocytes interactions in the presence or absence of an HIV peptide (HIV-3S peptide) shown to induce NK cell killing of CD4+ T cells during HIV-infection. Using a fusion protein consisting of the extracellular domain of NKp44 fused to Fc portion of human IgG, we determined the expression of a novel ligand for NKp44 (NKp44L) on astrocytes. Incubation of astrocytes with HIV-3S peptide downregulated NKp44L expression on astrocytes implicating protection from NK mediated killing. Thus, our study showed that NKp44 have a protective effect on astrocytes from NK cell mediated killing during HIV infection and impact astrocyte role in HAND. PMID- 29447243 TI - Differences in the intestinal microbiota between uninfected piglets and piglets infected with porcine epidemic diarrhea virus. AB - Porcine epidemic diarrhea, a disastrous gastrointestinal disease, causes great financial losses due to its high infectivity, morbidity and mortality in suckling piglets despite the development and application of various vaccines. In this study, high-throughput sequencing was used to explore differences in the intestinal microbiota between uninfected piglets and piglets infected with porcine epidemic diarrhea virus (PEDV). The results revealed that the small intestinal microbiota of suckling piglets infected with PEDV showed low diversity and was dominated by Proteobacteria (49.1%). Additionally, the composition of the small intestinal microbiota of sucking piglets infected with PEDV showed marked differences from that of the uninfected piglets. Some of the taxa showing differences in abundance between uninfected piglets and piglets infected with PEDV were associated with cellular transport and catabolism, energy metabolism, the biosynthesis of other secondary metabolites, and amino acid metabolism as determined through the prediction of microbial function based on the bacterial 16S rRNA gene. Therefore, adjusting the intestinal microbiota might be a promising method for the prevention or treatment of PEDV. PMID- 29447244 TI - Influence of hiatal hernia and male sex on the relationship between alcohol intake and occurrence of Barrett's esophagus. AB - BACKGROUND: The association of alcohol intake with the incidence of Barrett's esophagus (BE) has been inconsistent. Although hiatal hernia and male sex are well-known risk factors of BE, its effect on the association of alcohol intake with the incidence of BE remains unknown. AIM: To investigate whether the influence of alcohol intake on the occurrence of BE might differ depending on male sex and presence of hiatal hernia. METHODS: We utilized a database of 8031 patients that underwent upper endoscopy for health screening in a prospective, multicenter, cohort study (the Upper Gastro Intestinal Disease study). The incidence of endoscopic columnar-lined esophagus (eCLE; endoscopically diagnosed BE) was the outcome variable. Multivariable logistic regression analysis was conducted to assess the association between alcohol intake and eCLE stratified by male sex and hiatal hernia, adjusting for clinical features and other potential confounders. RESULTS: Alcohol intake (>=20 g/day) showed a marginally significant association with the incidence of eCLE in participants without hiatal hernia (0 vs. >=20 g/day; odds ratio [OR], 1.62; 95% confidence interval [CI], 0.92-2.85, P = 0.09) but not in participants with hiatal hernia (0 vs. >=20/day; OR, 0.99; 95% CI, 0.59-1.65; P = 0.95). Furthermore, alcohol intake (>=20 g/day) was significantly associated with the incidence of eCLE in male participants without hiatal hernia (0 vs. >=20 g/day; OR, 1.98; 95% CI, 1.04-4.03; P = 0.04) but not in female participants without hiatal hernia (0 vs. >=20 g/day; OR, 0.47; 95% CI, 0.03-2.37; P = 0.42). CONCLUSIONS: The effect of alcohol intake on the incidence of eCLE might be associated with hiatal hernia status and male sex. PMID- 29447245 TI - Adverse obstetric outcomes during delivery hospitalizations complicated by suicidal behavior among US pregnant women. AB - OBJECTIVE: The effects of suicidal behavior on obstetric outcomes remain dangerously unquantified. We sought to report on the risk of adverse obstetric outcomes for US women with suicidal behavior at the time of delivery. METHODS: We performed a cross-sectional analysis of delivery hospitalizations from 2007-2012 National (Nationwide) Inpatient Sample. From the same hospitalization record, International Classification of Diseases codes were used to identify suicidal behavior and adverse obstetric outcomes. Adjusted odds ratios (aOR) and 95% confidence intervals (CI) were obtained using logistic regression. RESULTS: Of the 23,507,597 delivery hospitalizations, 2,180 were complicated by suicidal behavior. Women with suicidal behavior were at a heightened risk for outcomes including antepartum hemorrhage (aOR = 2.34; 95% CI: 1.47-3.74), placental abruption (aOR = 2.07; 95% CI: 1.17-3.66), postpartum hemorrhage (aOR = 2.33; 95% CI: 1.61-3.37), premature delivery (aOR = 3.08; 95% CI: 2.43-3.90), stillbirth (aOR = 10.73; 95% CI: 7.41-15.56), poor fetal growth (aOR = 1.70; 95% CI: 1.10 2.62), and fetal anomalies (aOR = 3.72; 95% CI: 2.57-5.40). No significant association was observed for maternal suicidal behavior with cesarean delivery, induction of labor, premature rupture of membranes, excessive fetal growth, and fetal distress. The mean length of stay was longer for women with suicidal behavior. CONCLUSION: During delivery hospitalization, women with suicidal behavior are at increased risk for many adverse obstetric outcomes, highlighting the importance of screening for and providing appropriate clinical care for women with suicidal behavior during pregnancy. PMID- 29447246 TI - Fried food intake and risk of nonfatal acute myocardial infarction in the Costa Rica Heart Study. AB - Economic development in middle-income countries has led to a noticeable rise in the availability of commercial deep fried foods and lifestyles that require eating meals "on the go" and outside of the home. Yet, data from these countries where fried foods were traditionally prepared at home are scarce, despite several studies showing the potential adverse effects of fried food consumption on risk for heart disease. We aimed to examine whether consumption of fried foods inside or outside of the home is associated with an increased risk of myocardial infarction (MI) among Hispanic/Latinos living in Costa Rica. Participants were incident cases of a first acute MI (n = 2,154) and randomly selected controls matched for age, sex, and residence (n = 2,154). After adjustment for traditional cardiovascular risk factors, including history of diabetes, history of hypertension, smoking, abdominal obesity, income, educational years, occupation, alcohol intake, dietary intakes of saturated fatty acid, fiber intake, and total energy intake, the multivariable-adjusted odds ratio (OR, 95% CI) for risk of MI were 1.00 (reference), 1.02 (0.86-1.21), 1.26 (0.81-1.95), and 1.58 (1.08-2.30) for intake of fried foods outside of the home <1/week, 1-3/week, 4-6/week, and 1/day, respectively (P trend = 0.02); and 1.00, 0.81 (0.65-1.00), 0.81 (0.61 1.09), and 0.93 (0.72-1.19), respectively (P for trend = 0.65) for intake of fried foods inside the home. The data suggest that consumption of fried foods outside of the home, a practice that has been associated with economic development, could have adverse effects on cardiovascular disease. PMID- 29447247 TI - Differences between fellow eyes of acute and chronic primary angle closure (glaucoma): An ultrasound biomicroscopy quantitative study. AB - PURPOSE: To compare various biometric parameters between fellow eyes of acute primary angle closure (glaucoma) [APAC(G)] and fellow eyes of chronic primary angle closure (glaucoma) [CPAC(G)]. METHODS: Ultrasound biomicroscopy examinations were performed on 47 patients with unilateral APAC(G) and 41 patients with asymmetric CPAC(G) before laser peripheral iridotomy and pilocarpine treatment. Anterior chamber depth and width (ACD and ACW), lens vault (LV), iris curvature (IC), iris root distance (IRD), trabecular-ciliary process distance (TCPD), iris-ciliary process distance (ICPD), trabecular-ciliary angle (TCA), and other biometric parameters were compared between fellow eyes of APAC(G) and fellow eyes of CAPC(G). RESULTS: Compared with fellow eyes of CPAC(G), fellow eyes of APAC(G) had smaller ACD (P < 0.001), ACW (P = 0.007), TCPD (P = 0.016), ICPD (P = 0.008), and TCA (P = 0.006), as well as larger LV (P = 0.002), IC (P = 0.012), and IRD (P = 0.003). On multivariate logistic regression analyses, a 0.1 mm decrease in ACD (odds ratio [OR]: 0.705, 95%CI: 0.564-0.880, P = 0.002), ICPD (OR: 0.557, 95%CI: 0.335-0.925, P = 0.024), and a 0.1 mm increase in IRD (OR: 2.707, 95%CI: 1.025-7.149, P = 0.045), was significantly associated with occurrence of acute angle closures. CONCLUSIONS: Fellow eyes of APAC(G) had smaller anterior segment dimensions, higher LV, more posterior iris insertion, greater IC, and more anteriorly rotated ciliary body compared with fellow eyes of CPAC(G). ACD, ICPD, and IRD were the three most important parameters that distinguish eyes predisposed to APAC(G) or CPAC(G). PMID- 29447248 TI - Effect of park prescriptions with and without group visits to parks on stress reduction in low-income parents: SHINE randomized trial. AB - INTRODUCTION: Exposure to nature may reduce stress in low-income parents. This prospective randomized trial compares the effect of a physician's counseling about nature with or without facilitated group outings on stress and other outcomes among low-income parents. MATERIALS AND METHODS: Parents of patients aged 4-18 years at a clinic serving low-income families were randomized to a supported park prescription versus independent park prescription in a 2:1 ratio. Parents in both groups received physician counseling about nature, maps of local parks, a journal, and pedometer. The supported group received additional phone and text reminders to attend three weekly family nature outings with free transportation, food, and programming. Outcomes measured in parents at baseline, one month and three months post-enrollment included: stress (using the 40-point Perceived Stress Scale [PSS10]); park visits per week (self-report and journaling); loneliness (modified UCLA-Loneliness Scale); physical activity (self report, journaling, pedometry); physiologic stress (salivary cortisol); and nature affinity (validated scale). RESULTS: We enrolled 78 parents, 50 in the supported and 28 in the independent group. One-month follow-up was available for 60 (77%) participants and three-month follow up for 65 (83%). Overall stress decreased by 1.71 points (95% CI, -3.15, -0.26). The improvement in stress did not differ significantly by group assignment, although the independent group had more park visits per week (mean difference 1.75; 95% CI [0.46, 3.04], p = 0.0085). In multivariable analysis, each unit increase in park visits per week was associated with a significant and incremental decrease in stress (change in PSS10-0.53; 95% CI [-0.89, -0.16]; p = 0.005) at three months. CONCLUSION: While we were unable to demonstrate the additional benefit of group park visits, we observed an overall decrease in parental stress both overall and as a function of numbers of park visits per week. Paradoxically the park prescription without group park visits led to a greater increase in weekly park visits than the group visits. To understand the benefits of this intervention, larger trials are needed. TRIAL REGISTRATION: ClinicalTrials.gov NCT02623855. PMID- 29447250 TI - Correction: STING expression and response to treatment with STING ligands in premalignant and malignant disease. AB - [This corrects the article DOI: 10.1371/journal.pone.0187532.]. PMID- 29447249 TI - A paralogous pair of mammalian host restriction factors form a critical host barrier against poxvirus infection. AB - Host restriction factors constitute a formidable barrier for viral replication to which many viruses have evolved counter-measures. Human SAMD9, a tumor suppressor and a restriction factor for poxviruses in cell lines, is antagonized by two classes of poxvirus proteins, represented by vaccinia virus (VACV) K1 and C7. A paralog of SAMD9, SAMD9L, is also encoded by some mammals, while only one of two paralogs is retained by others. Here, we show that SAMD9L functions similarly to SAMD9 as a restriction factor and that the two paralogs form a critical host barrier that poxviruses must overcome to establish infection. In mice, which naturally lack SAMD9, overcoming SAMD9L restriction with viral inhibitors is essential for poxvirus replication and pathogenesis. While a VACV deleted of both K1 and C7 (vK1L-C7L-) was restricted by mouse cells and highly attenuated in mice, its replication and virulence were completely restored in SAMD9L-/- mice. In humans, both SAMD9 and SAMD9L are poxvirus restriction factors, although the latter requires interferon induction in many cell types. While knockout of SAMD9 with Crispr-Cas9 was sufficient for abolishing the restriction for vK1L-C7L- in many human cells, knockout of both paralogs was required for abolishing the restriction in interferon-treated cells. Both paralogs are antagonized by VACV K1, C7 and C7 homologs from diverse mammalian poxviruses, but mouse SAMD9L is resistant to the C7 homolog encoded by a group of poxviruses with a narrow host range in ruminants, indicating that host species-specific difference in SAMD9/SAMD9L genes serves as a barrier for cross-species poxvirus transmission. PMID- 29447251 TI - Attention to fat- and thin-related words in body-satisfied and body-dissatisfied women before and after thin model priming. AB - Understanding the cognitive processes underlying body dissatisfaction provides important information on the development and perpetuation of eating pathology. Previous research suggests that body-dissatisfied women process weight-related information differently than body-satisfied women, but the precise nature of these processing differences is not yet understood. In this study, eye-gaze tracking was used to measure attention to weight-related words in body dissatisfied (n = 40) and body-satisfied (n = 38) women, before and after exposure to images of thin fashion models. Participants viewed 8-second displays containing fat-related, thin-related, and neutral words while their eye fixations were tracked and recorded. Based on previous research and theory, we predicted that body-dissatisfied women would attend to fat-related words more than body satisfied women and would attend to thin-related words less. It was also predicted that exposure to thin model images would increase self-rated body dissatisfaction and heighten group differences in attention. The results indicated that body-dissatisfied women attended to both fat- and thin-related words more than body-satisfied women and that exposure to thin models did not increase this effect. Implications for cognitive models of eating disorders are discussed. PMID- 29447252 TI - Low-back electromyography (EMG) data-driven load classification for dynamic lifting tasks. AB - OBJECTIVE: Numerous devices have been designed to support the back during lifting tasks. To improve the utility of such devices, this research explores the use of preparatory muscle activity to classify muscle loading and initiate appropriate device activation. The goal of this study was to determine the earliest time window that enabled accurate load classification during a dynamic lifting task. METHODS: Nine subjects performed thirty symmetrical lifts, split evenly across three weight conditions (no-weight, 10-lbs and 24-lbs), while low-back muscle activity data was collected. Seven descriptive statistics features were extracted from 100 ms windows of data. A multinomial logistic regression (MLR) classifier was trained and tested, employing leave-one subject out cross-validation, to classify lifted load values. Dimensionality reduction was achieved through feature cross-correlation analysis and greedy feedforward selection. The time of full load support by the subject was defined as load-onset. RESULTS: Regions of highest average classification accuracy started at 200 ms before until 200 ms after load-onset with average accuracies ranging from 80% (+/-10%) to 81% (+/ 7%). The average recall for each class ranged from 69-92%. CONCLUSION: These inter-subject classification results indicate that preparatory muscle activity can be leveraged to identify the intent to lift a weight up to 100 ms prior to load-onset. The high accuracies shown indicate the potential to utilize intent classification for assistive device applications. SIGNIFICANCE: Active assistive devices, e.g. exoskeletons, could prevent back injury by off-loading low-back muscles. Early intent classification allows more time for actuators to respond and integrate seamlessly with the user.

AB - OBJECTIVES: The objective of the current study was to understand the added effects of having a sensory impairment (vision and/or hearing impairment) in combination with cognitive impairment with respect to health-related outcomes among older adults (65+ years old) receiving home care or residing in a long-term care (LTC) facility in Ontario, Canada. METHODS: Cross-sectional analyses were conducted using existing data collected with one of two interRAI assessments, one for home care (n = 291,824) and one for LTC (n = 110,578). Items in the assessments were used to identify clients with single sensory impairments (e.g., vision only [VI], hearing only [HI]), dual sensory impairment (DSI; i.e., vision and hearing) and those with cognitive impairment (CI). We defined seven mutually exclusive groups based on the presence of single or combined impairments. RESULTS: The rate of people having all three impairments (i.e., CI+DSI) was 21.3% in home care and 29.2% in LTC. Across the seven groups, individuals with all three impairments were the most likely to report loneliness, to have a reduction in social engagement, and to experience reduced independence in their activities of daily living (ADLs) and instrumental ADLs (IADLs). Communication challenges were highly prevalent in this group, at 38.0% in home care and 49.2% in LTC. In both care settings, communication difficulties were more common in the CI+DSI group versus the CI-alone group. CONCLUSIONS: The presence of combined sensory and cognitive impairments is high among older adults in these two care settings and having all three impairments is associated with higher rates of negative outcomes than the rates for those having CI alone. There is a rising imperative for all health care professionals to recognize the potential presence of hearing, vision and cognitive impairments in those for whom they provide care, to ensure that basic screening occurs and to use those results to inform care plans. PMID- 29447254 TI - Loop diuretics are associated with greater risk of sarcopenia in patients with non-dialysis-dependent chronic kidney disease. AB - INTRODUCTION: Sarcopenia, the age-related loss of muscle mass and function, frequently accompanies chronic kidney disease. The aim of this study was to clarify the prevalence and the risk factors for sarcopenia among patients with non-dialysis-dependent chronic kidney disease (NDD-CKD), focusing on the use of drugs. METHODS: We conducted a cross-sectional analysis on a cohort of 260 patients with NDD-CKD in a university hospital, recruited between June 2016 and March 2017. We extracted data on patient gender, age, cause of chronic kidney disease, use of drugs, and comorbidities that could potentially affect the prevalence of sarcopenia. Sarcopenia was diagnosed using the criteria of the Asian Working Group for Sarcopenia. Logistic regression analysis was performed to analyze the association of each factor on the prevalence of sarcopenia. RESULTS: 25.0% of our study subjects had sarcopenia. Multivariable analysis revealed that an increased risk of sarcopenia was significantly associated with age, male gender, body mass index, diabetes mellitus, and loop diuretic use (odds ratio, 4.59: 95% confidence interval, 1.81-11.61: P-value 0.001). CONCLUSIONS: In our cohort, the prevalence of sarcopenia in patients with NDD-CKD was high, and diuretics use, particularly loop diuretic use, was suggested to be a risk factor of sarcopenia. Although loop diuretics are commonly used in patients with CKD, careful consideration of the risk of sarcopenia may be necessary. PMID- 29447255 TI - Hydroxyethyl starch for volume expansion after subarachnoid haemorrhage and renal function: Results of a retrospective analysis. AB - BACKGROUND: Hydroxyethyl starch (HES) was part of "triple-H" therapy for prophylaxis and therapy of vasospasm in patients with subarachnoid haemorrhage (SAH). The European Medicines Agency restricted the use of HES in 2013 due to an increase of renal failure in critically ill patients receiving HES compared to crystalloid fluids. The occurrence of renal insufficiency in patients with SAH due to HES is still uncertain. The purpose of our study was to evaluate whether there was an association with renal impairment in patients receiving HES after subarachnoid haemorrhage. METHODS: Medical records of all non-traumatic SAH patients treated at the Departments of Anaesthesiology and Neurosurgery, University Hospital of Leipzig, Germany, between January 2009 and December 2014 were analysed. Patients received either HES 6% and/or 10% (HES group, n = 183) or exclusively crystalloids for fluid therapy (Crystalloid group, n = 93). Primary outcome was the incidence of acute kidney injury. RESULTS: The study groups had similar characteristics except for initial SAPS scores, incidence of vasospasm and ICU length of stay. Patients receiving HES fulfilled significantly more often SIRS (systemic inflammatory response syndrome) criteria. 24.6% (45/183) of the patients in the HES group had acute kidney injury (KDIGO 1-3) at any time during their ICU stay compared to 26.9% (25/93) in the crystalloid group (p = 0.679). Only few patients needed renal replacement therapy with no significant difference between groups (Crystalloid group: 4.3%; HES group: 2.2%; p = 0.322). The incidence of vasospasm was increased in the HES group when compared to the crystalloid group (33.9% vs. 17.2%; p = 0.004). CONCLUSION: In the presented series of patients with non-traumatic SAH we found no significant association between HES therapy and the incidence of acute kidney injury. Treatment without HES did not worsen patient outcome. PMID- 29447256 TI - Modulation of neural circuits underlying temporal production by facial expressions of pain. AB - According to the Scalar Expectancy Theory, humans are equipped with a biological internal clock, possibly modulated by attention and arousal. Both emotions and pain are arousing and can absorb attentional resources, thus causing distortions of temporal perception. The aims of the present single-event fMRI study were to investigate: a) whether observation of facial expressions of pain interferes with time production; and b) the neural network subserving this kind of temporal distortions. Thirty healthy volunteers took part in the study. Subjects were asked to perform a temporal production task and a concurrent gender discrimination task, while viewing faces of unknown people with either pain related or neutral expressions. Behavioural data showed temporal underestimation (i.e., longer produced intervals) during implicit pain expression processing; this was accompanied by increased activity of right middle temporal gyrus, a region known to be active during the perception of emotional and painful faces. Psycho-Physiological Interaction analyses showed that: 1) the activity of middle temporal gyrus was positively related to that of areas previously reported to play a role in timing: left primary motor cortex, middle cingulate cortex, supplementary motor area, right anterior insula, inferior frontal gyrus, bilateral cerebellum and basal ganglia; 2) the functional connectivity of supplementary motor area with several frontal regions, anterior cingulate cortex and right angular gyrus was correlated to the produced interval during painful expression processing. Our data support the hypothesis that observing emotional expressions distorts subjective time perception through the interaction of the neural network subserving processing of facial expressions with the brain network involved in timing. Within this frame, middle temporal gyrus appears to be the key region of the interplay between the two neural systems. PMID- 29447257 TI - Access to health insurance coverage among sub-Saharan African migrants living in France: Results of the ANRS-PARCOURS study. AB - BACKGROUND: Migrants' access to care depends on their health insurance coverage in the host country. We aimed to evaluate in France the dynamic and the determinants of health insurance coverage acquisition among sub-Saharan migrants. METHODS: In the PARCOURS life-event retrospective survey conducted in 2012-2013 in health-care facilities in the Paris region, data on health insurance coverage (HIC) each year since arrival in France has been collected among three groups of sub-Saharan migrants recruited in primary care centres (N = 763), centres for HIV care (N = 923) and for chronic hepatitis B care (N = 778). Year to year, the determinants of the acquisition and lapse of HIC were analysed with mixed-effects logistic regression models. RESULTS: In the year of arrival, 63.4% of women and 55.3% of men obtained HIC. But three years after arrival, still 14% of women and 19% of men had not obtained HIC. HIC acquisition was accelerated in case of HIV or hepatitis B infection, for migrants arrived after 2000, and for women in case of pregnancy and when they were studying. Conversely, it was slowed down in case of lack of a residency permit and lack of financial resources for men. In addition, women and men without residency permits were more likely to have lost HIC when they had one. CONCLUSION: In France, the health insurance system aiming at protecting all, including undocumented migrants, leads to a prompt access to HIC for migrants from sub-Saharan Africa. Nevertheless, this access may be impaired by administrative and social insecurities. PMID- 29447258 TI - The time-series behavior of neutrophil-to-lymphocyte ratio is useful as a predictive marker in non-small cell lung cancer. AB - BACKGROUND: Nivolumab improves the survival of advanced non-small cell lung cancer (NSCLC), but a significant number of patients still fail to benefit from this treatment. In this study, we evaluated the efficacy of the time-series behavior of neutrophil-to-lymphocyte ratio (NLR) in a complete blood count from advanced NSCLC patients as a predictive marker of the anticancer effect of nivolumab. METHODS: We performed a retrospective review of medical records and collected data on patients with advanced NSCLC treated with nivolumab as second- and further-line treatments from December 2015 to March 2017. The NLRs were calculated before each treatment cycle for four cycles. These parameters were tested for its association with the overall survival (OS), progression-free survival (PFS) and time to treatment failure (TTF). RESULTS: Nineteen patients were treated with nivolumab. Stratified by the response to nivolumab, the median OS was 2.8 months in progressive disease (PD) and 14.0 months in non-PD (p = 0.002). Before discontinuation of PD or toxicity, an NLR is rising from baseline in 5 out of 7 patients with PD and all of 4 patients with discontinuation due to toxicity. Patients with an >30% increase in NLR were associated with a significantly shorter TTF compared with those with stable or decrease in NLR both after first cycle (p = 0.014) and second cycle (p < 0.001). CONCLUSIONS: The NLR is suggested to be useful not only as a prognostic marker but also as a predictive marker for treatment with nivolumab. Further prospective study is warranted to develop a predictive algorithm to detect PD cases as early as possible by focusing the time-series behavior of NLR. PMID- 29447259 TI - Medical professionalism of foreign-born and foreign-trained physicians under close scrutiny: A qualitative study with stakeholders in Germany. AB - Hospitals in Germany employ increasing numbers of foreign-born and foreign trained (FB&FT) physicians. Studies have investigated how FB&FT physicians experience their professional integration into the German healthcare system, however, the perspectives of stakeholders working with and shaping the work experiences of FB&FT physicians in German hospitals have so far been neglected. This study explores relevant stakeholders' opinions and attitudes towards FB&FT physicians-which likely influence how these physicians settle in-and how these opinions were formed. We conducted a qualitative interview study with 25 stakeholders working in hospitals or in health policy development. The interviews were analyzed within a constructivist research paradigm using methods derived from Grounded Theory (situational analysis as well as open, axial and selective coding). We found that stakeholders tended to focus on problems in FB&FT physicians' work performance. Participants criticized FB&FT physicians' work for deviating from presumably shared professional standards (skill or knowledge and behavioral standards). The professional standards invoked to justify problem focused statements comprised the definition of an ideal behavior, attitude or ability and a tolerance range that was adapted in a dynamic process. Behavior falling outside the tolerance range was criticized as unacceptable, requiring action to prevent similar deviations in the future. Furthermore, we derived three strategies (minimization, homogenization and quality management) proposed by participants to manage deviations from assumed professional standards by FB&FT physicians. We critically reflect on the social processes of evaluation and problematization and question the legitimacy of professional standards invoked. We also discuss discriminatory tendencies visible in evaluative statements of some participants as well as in some of the strategies proposed. We suggest it will be key to develop and implement better support strategies for FB&FT physicians while also addressing problematic attitudes within the receiving system to further professional integration. PMID- 29447260 TI - Optimal dose reduction algorithm using an attenuation-based tube current modulation method for cone-beam CT imaging. AB - To reduce the radiation dose given to patients, a tube current modulation (TCM) method has been widely used in diagnostic CT systems. However, the TCM method has not yet been applied to a kV-CBCT system on a LINAC machine. The purpose of this study is to investigate if a TCM method would be desirable in a kV-CBCT system for image-guided radiation therapy (IGRT) or not. We have developed an attenuation-based TCM method using prior knowledge from planning CT images of patients. The TCM method can provide optimized dose reductions without degrading image quality for kV-CBCT imaging. Here, we investigate whether or not our suggested TCM method is desirable to use in kV-CBCT systems to confirm and revise the exact position of a patient for IGRT. Patients go through diagnostic CT scans for RT planning; therefore, using information from prior CT images can enable estimations of the total X-ray attenuation through a patient's body in a CBCT setting for radiation treatment. Having this planning CT image allows to use the proposed TCM method in RT. The proposed TCM method provides a minimal amount of current for each projection, as well as total current, required to reconstruct the current modulated CBCT image with an image quality similar to that of CBCT. After applying a calculated TCM current for each projection, projection images were acquired and the current modulated CBCT image was reconstructed using a FDK algorithm. To validate the proposed approach, we used a numerical XCAT phantom and a real ATOM phantom and evaluated the performance of the proposed method via visual and quantitative image quality metrics. The organ dose due to imaging radiation was calculated in both cases and compared using the GATE simulation toolkit. As shown in the quantitative evaluation, normalized noise and SSIM values of the TCM were similar to those of conventional CBCT images. In addition, the proposed TCM method yielded comparable image quality to that of conventional CBCT images for both simulations and experimental studies as organ doses were decreased. We have successfully demonstrated the feasibility and dosimetric merit of a prototypical TCM method for kV-CBCT via simulations and experimental study. The results indicate that the proposed TCM method and overall framework can be a viable option for CBCT imaging that utilizes an optimal dose reduction without degrading image quality. Thus, this method reduces the probability for side effects due to radiation exposure. PMID- 29447261 TI - Relationship between serum bilirubin levels and cardiovascular disease. AB - We tested the hypothesis that higher levels of bilirubin, a bile pigment with antioxidant properties, are associated with a decreased risk of cardiovascular disease (CVD). This study analyzed data from the Korean Health and Genome Study to examine the association between serum total bilirubin (TB) on CVD and CVD death. Serum TB was measured in a total of 8,844 subjects (4,196 males and 4,648 females) and evaluated for the development of new onset CVD from 2001 to 2012 (mean 8.1 years of follow-up). During the follow-up period, 689 cases of incident CVD (7.8%) were identified, and the prevalence of metabolic syndrome (MetS) at baseline was 26.1%. The prevalence of MetS decreased across bilirubin tertile categories. In addition to MetS itself, individual components of MetS significantly decreased with increased bilirubin tertiles. Moreover, the incidence of CVD decreased across bilirubin tertile categories. The hazard ratios (HRs) for developing coronary heart disease (CHD, HR 0.769, 95% CI 0.655-1.000) and CVD death (HR 0.513, 95% CI 0.267-0.985) was significantly lower in the highest tertile group (> 0.63 mg/dL) in comparison to the lowest tertile group (< 0.44 mg/dL) after adjusting for all confounding variables. In the present longitudinal study, a significant negative relationship was demonstrated between baseline bilirubin levels and incident CHD and CVD death. PMID- 29447262 TI - Long-term use of cover crops and no-till shift soil microbial community life strategies in agricultural soil. AB - Reducing tillage and growing cover crops, widely recommended practices for boosting soil health, have major impacts on soil communities. Surprisingly little is known about their impacts on soil microbial functional diversity, and especially so in irrigated Mediterranean ecosystems. In long-term experimental plots at the West Side Research and Extension Center in California's Central Valley, we characterized soil microbial communities in the presence or absence of physical disturbance due to tillage, in the presence or absence of cover crops, and at three depths: 0-5, 5-15 and 15-30 cm. This characterization included qPCR for bacterial and archaeal abundances, DNA sequencing of the 16S rRNA gene, and phylogenetic estimation of two ecologically important microbial traits (rRNA gene copy number and genome size). Total (bacterial + archaeal) diversity was higher in no-till than standard till; diversity increased with depth in no-till but decreased with depth in standard till. Total bacterial numbers were higher in cover cropped plots at all depths, while no-till treatments showed higher numbers in 0-5 cm but lower numbers at lower depths compared to standard tillage. Trait estimates suggested that different farming practices and depths favored distinctly different microbial life strategies. Tillage in the absence of cover crops shifted microbial communities towards fast growing competitors, while no till shifted them toward slow growing stress tolerators. Across all treatment combinations, increasing depth resulted in a shift towards stress tolerators. Cover crops shifted the communities towards ruderals-organisms with wider metabolic capacities and moderate rates of growth. Overall, our results are consistent with decreasing nutrient availability with soil depth and under no till treatments, bursts of nutrient availability and niche homogenization under standard tillage, and increases in C supply and variety provided by cover crops. Understanding how agricultural practices shift microbial abundance, diversity and life strategies, such as presented here, can assist with designing farming systems that can support high yields, while enhancing C sequestration and increasing resilience to climate change. PMID- 29447263 TI - Insurance status and cancer treatment mediate the association between race/ethnicity and cervical cancer survival. AB - Cervical cancer outcomes remain poor among disadvantaged populations, including ethnic minorities, low-income, and underinsured women. The aim of this study was to evaluate the mechanisms that underlie the observed association between race/ethnicity and cervical cancer survival. We identified 13,698 women, ages 21 to 64 years, diagnosed with stages I-III primary cervical cancer between 2007 2013 in Surveillance, Epidemiology, and End Results (SEER). Multivariable Cox proportional hazards regression models evaluated associations between race/ethnicity (Non-Hispanic White, Non-Hispanic Black, Hispanic, Other) and cervical cancer-specific mortality. We conducted mediation analysis to calculate the mediation proportion and its 95% confidence interval. Non-Hispanic black women had an increased risk of cervical cancer-specific mortality (HR: 1.23, 95% CI: 1.08-1.39), and Hispanic women a decreased risk of dying from their disease (HR: 0.82, 95% CI: 0.72-0.93), compared with non-Hispanic white. The estimated proportion of excess cervical cancer mortality for non-Hispanic black women relative to non-Hispanic white women that was mediated by insurance was 18.6% and by treatment was 47.2%. Furthermore, non-Hispanic black women were more likely to receive radiation and less likely to receive surgery for early-stage disease. In this population-based study we found that some of the excess cervical cancer specific mortality for non-Hispanic black women is mediated by factors such as insurance status and treatment. These findings suggest that enhancing existing insurance coverage and ensuring equal and adequate treatment in all women may be a key strategy for improving cervical cancer outcomes. PMID- 29447264 TI - Ebselen alleviates testicular pathology in mice with Zika virus infection and prevents its sexual transmission. AB - Despite the low case fatality, Zika virus (ZIKV) infection has been associated with microcephaly in infants and Guillain-Barre syndrome. Antiviral and vaccine developments against ZIKV are still ongoing; therefore, in the meantime, preventing the disease transmission is critical. Primarily transmitted by Aedes species mosquitoes, ZIKV also can be sexually transmitted. We used AG129 mice lacking interferon-alpha/beta and -gamma receptors to study the testicular pathogenesis and sexual transmission of ZIKV. Infection of ZIKV progressively damaged mouse testes, increased testicular oxidative stress as indicated by the levels of reactive oxygen species, nitric oxide, glutathione peroxidase 4, spermatogenesis-associated-18 homolog in sperm and pro-inflammatory cytokines including IL-1beta, IL-6, and G-CSF. We then evaluated the potential role of the antioxidant ebselen (EBS) in alleviating the testicular pathology with ZIKV infection. EBS treatment significantly reduced ZIKV-induced testicular oxidative stress, leucocyte infiltration and production of pro-inflammatory response. Furthermore, it improved testicular pathology and prevented the sexual transmission of ZIKV in a male-to-female mouse sperm transfer model. EBS is currently in clinical trials for various diseases. ZIKV infection could be on the list for potential use of EBS, for alleviating the testicular pathogenesis with ZIKV infection and preventing its sexual transmission. PMID- 29447266 TI - Engineered resistance to Nosema bombycis by in vitro expression of a single-chain antibody in Sf9-III cells. AB - Nosema bombycis is a destructive, obligate intracellular parasite of the Bombyx mori. In this study, a single-chain variable fragment (scFv) dependent technology is developed for the purpose of inhibiting parasite proliferation in insect cells. The scFv-G4, which we prepared from a mouse G4 monoclonal antibody, can target the N. bombycis spore wall protein 12 (NbSWP12). Indirect immunofluorescence assays showed that NbSWP12 located mainly on the outside of the N. bombycis cytoskeleton, although some of it co-localized with beta-tubulin in the meront-stage of parasites. When meront division began, NbSWP12 became concentrated at both ends of each meront. Western blotting showed that scFv-G4 could express in Sf9-III cells and recognized native NbSWP12. The transgenic Sf9 III cell line showed better resistance than the controls when challenged with N. bombycis, indicating that NbSWP12 is a promising target in this parasite and this scFv dependent strategy could be a solution for construction of N. bombycis resistant Bombyx mori. PMID- 29447265 TI - Dynamic remodeling of lipids coincides with dengue virus replication in the midgut of Aedes aegypti mosquitoes. AB - We describe the first comprehensive analysis of the midgut metabolome of Aedes aegypti, the primary mosquito vector for arboviruses such as dengue, Zika, chikungunya and yellow fever viruses. Transmission of these viruses depends on their ability to infect, replicate and disseminate from several tissues in the mosquito vector. The metabolic environments within these tissues play crucial roles in these processes. Since these viruses are enveloped, viral replication, assembly and release occur on cellular membranes primed through the manipulation of host metabolism. Interference with this virus infection-induced metabolic environment is detrimental to viral replication in human and mosquito cell culture models. Here we present the first insight into the metabolic environment induced during arbovirus replication in Aedes aegypti. Using high-resolution mass spectrometry, we have analyzed the temporal metabolic perturbations that occur following dengue virus infection of the midgut tissue. This is the primary site of infection and replication, preceding systemic viral dissemination and transmission. We identified metabolites that exhibited a dynamic-profile across early-, mid- and late-infection time points. We observed a marked increase in the lipid content. An increase in glycerophospholipids, sphingolipids and fatty acyls was coincident with the kinetics of viral replication. Elevation of glycerolipid levels suggested a diversion of resources during infection from energy storage to synthetic pathways. Elevated levels of acyl-carnitines were observed, signaling disruptions in mitochondrial function and possible diversion of energy production. A central hub in the sphingolipid pathway that influenced dihydroceramide to ceramide ratios was identified as critical for the virus life cycle. This study also resulted in the first reconstruction of the sphingolipid pathway in Aedes aegypti. Given conservation in the replication mechanisms of several flaviviruses transmitted by this vector, our results highlight biochemical choke points that could be targeted to disrupt transmission of multiple pathogens by these mosquitoes. PMID- 29447267 TI - Tricked or trapped-Two decoy mechanisms in host-pathogen interactions. PMID- 29447268 TI - Circulating small non-coding RNAs reflect IFN status and B cell hyperactivity in patients with primary Sjogren's syndrome. AB - BACKGROUND: Considering the important role of miRNAs in the regulation of post transcriptional expression of target genes, we investigated circulating small non coding RNAs (snc)RNA levels in patients with primary Sjogren's syndrome (pSS). In addition we assessed if serum sncRNA levels can be used to differentiate patients with specific disease features. METHODS: Serum RNA was isolated from 37 pSS patients as well as 21 patients with incomplete Sjogren's Syndrome (iSS) and 17 healthy controls (HC) allocated to two independent cohorts: discovery and validation. OpenArray profiling of 758 sncRNAs was performed in the discovery cohort. Selected sncRNAs were measured in the validation cohort using single assay RT-qPCR. In addition, unsupervised hierarchical clustering was performed within the pSS group. RESULTS: Ten sncRNAs were differentially expressed between the groups in the array. In the validation cohort, we confirmed the increased expression of U6-snRNA and miR-661 in the iSS group as compared to HC. We were unable to validate differential expression of any miRNAs in the pSS group. However, within this group several miRNAs correlated with laboratory parameters. Unsupervised clustering distinguished three clusters of pSS patients. Patients in one cluster showed significantly higher serum IgG, prevalence of anti-SSB autoantibodies, IFN-score, and decreased leukocyte counts compared to the two other clusters. CONCLUSION: We were unable to identify any serum sncRNAs with differential expression in pSS patients. However, we show that circulating miRNA levels are associated with disease parameters in pSS patients and can be used to distinguish pSS patients with more severe B cell hyperactivity. As several of these miRNAs are implicated in the regulation of B cells, they may play a role in the perpetuation of the disease.

AB - The greenhouse whitefly Trialeurodes vaporariorum (Westwood) (Hemiptera: Aleyrodidae) is a pest of a wide range of vegetable and ornamental crops in greenhouses around the world. Yellow sticky traps are highly attractive to flying adults and so are frequently used to monitor the pest. Our aim was to test whether changes in trap translucency or the addition of printed black patterns could increase the catch on yellow sticky traps in greenhouses. Field trials were carried out in commercial crops of strawberry and tomato under glass over three years. Reduced trap translucency increased trap catches by a factor of 1.5 to 7.0 and the catch increased significantly for both females and males. Spectrometer measurements showed that the increased catch was consistent with an increased landing stimulus from a colour opponency mechanism i.e. the ratio of energy from 500-640 nm to the energy from 300-500 nm. Printed black patterns increased trap catches on specific types of trap, by a factor of 1.4 to 2.3, and the catch increased significantly for both females and males. The patterns increased trap catch on moderately translucent traps, but decreased trap catch on less translucent traps. The evidence points to a contrast/edge effect of pattern, but laboratory experiments are needed to clarify this. Exploitation of these translucency and pattern effects could improve the efficacy of yellow traps for monitoring and mass trapping in crops. PMID- 29447271 TI - Parents' knowledge, beliefs, and acceptance of the HPV vaccination in relation to their socio-demographics and religious beliefs: A cross-sectional study in Thailand. AB - Thailand has one of the world's highest prevalence of cervical cancer, mainly caused by the human papillomavirus (HPV). HPV infections can successfully be prevented by vaccination, which is available at a cost but not yet implemented in the national vaccination program. Parents play a critical role in deciding whether to vaccinate their child against HPV. Thus, the aim was to examine the association between parents' knowledge, beliefs, and acceptance of the HPV vaccination for their daughters, considering their socio-demographics and religious beliefs. A cross-sectional design was used among three schools in Thailand: Nakorn Phatom province (suburban) and Bangkok (urban). Parents of 9-12 year-old daughters completed the questionnaires, guided by the Health Belief Model. In total, 359 parents completed the questionnaires; of those, 301 were included in the final analyses. The ordinary least squares (OLS) regression analysis showed that background knowledge of HPV and the HPV vaccine was positively related to knowledge of HPV and cervical cancer. For beliefs, knowledge was positively associated with susceptibility (i.e., parents' perceived risk of an HPV infection/ related disease), severity, and benefit. However, knowledge was not significantly related to barriers. For acceptance, higher susceptibility and benefit were related to higher acceptance, and greater knowledge was associated with higher acceptance. Thus, we found associations between parents' knowledge, beliefs, and acceptance of the HPV vaccination for their daughters, considering their socio-demographics and religious beliefs. Parents, who reported religion as important, as opposed to those who did not, were more favorable toward the HPV vaccination. Four out of ten mothers had never undergone a cervical cancer screening, but most had accepted previous childhood vaccinations for their daughters. The overall acceptance of the vaccine was high, and we believe our results are promising for future implementation of the HPV vaccination in the national childhood vaccination program in Thailand. PMID- 29447273 TI - Molecular epidemiology and drug sensitivity pattern of Mycobacterium tuberculosis strains isolated from pulmonary tuberculosis patients in and around Ambo Town, Central Ethiopia. AB - INTRODUCTION: Tuberculosis (TB) is caused by M. tuberculosis complex and remains a major global public health problem. The epidemic remains a threat to sub Saharan Africa, including Ethiopia, with further emergence of drug resistant TB. We investigated the drug sensitivity pattern and molecular epidemiology of mycobacterial strains isolated from pulmonary TB patients in and around Ambo town in Oromia Region, Central Ethiopia. METHODS: A cross-sectional study was conducted involving 105 consecutive new smear positive pulmonary TB patients diagnosed at Ambo Hospital and surrounding Health Centers between May 2014 and March 2015 upon informed consent. Sputum samples were cultured on Lowenstein Jensen (LJ) media using standard techniques to isolate mycobacteria. Region of difference 9 (RD9)-based polymerase chain reaction (PCR) and spoligotyping was employed for the identification of the isolates at species and strain levels. The spoligotype patterns were entered into the SITVIT database to determine Octal and SIT (Spoligotyping International Typing) numbers for each strain. The sensitivity of the isolates to isoniazid (INH), rifampicin (RIF), ethambutol (ETB) and streptomycin (STM) was evaluated on LJ-medium with the indirect proportion method. RESULTS: Cultures were positive in 86/105 (82%) of newly diagnosed smear positive pulmonary TB cases. All of the 86 isolates were confirmed as M. tuberculosis. The majority (76.7%) of them were clustered into seven groups while the rest (23.3%) appeared unique. The most predominant Spoligotypes were SIT53 and SIT149, consisting of 24.4% and 20.9% of the isolates, respectively. Assigning of the isolates to family using SPOTCLUST software revealed that 45.3% of the isolates belonged to T1, 23.3% to T3 and 13% to CAS family. The majority (76.7%) of the M. tuberculosis isolates were susceptible to all the four drugs. Any resistance to any one of the four drugs was detected in 23.3% of the isolates. The highest proportion of any resistance was observed against isoniazid (9.3%) and ethambutol (7%). There was only a single case (1.2%) of multidrug resistant/rifampicin resistant (MDR/RR) TB. CONCLUSION: The majority of the isolates were clustered suggesting on-going active transmission in the study area. Mono resistance is relatively prevalent while the magnitude of MDR/RR-TB was found to be lower than in previous studies. PMID- 29447274 TI - Health literacy of hospital patients using a linguistically validated Croatian version of the Newest Vital Sign screening test (NVS-HR). AB - The Newest Vital Sign (NVS) is a simple, quick and accurate screening test for health literacy (HL). It has been validated for different languages but, to date, not for the Croatian language. The aim of this study was to develop a linguistically validated Croatian version of the NVS and to use it at a later stage in a pilot study of health literacy assessment of hospital patients in Croatia. A full linguistic validation procedure was applied, including forward and backward translation, expert panel review, cognitive interview with 10 respondents from general population, and full involvement in the procedure of one of the screening test developers, the lead author of the NVS-UK version. HL testing on 100 hospital patients (55% women, median age 63.5 years) revealed 58% of patients had less than adequate HL level (scores less than 4), and mean NVS total score was 3.34. A positive significant association was observed between HL and educational level (p = 0.002). A high percentage of patients (92%) did not object to being tested for HL by their primary care physician or in hospital, and 99% of patients would recommend HL testing among patients in general. The respondents' positive views on HL testing and mean completion time of 4 minutes indicate that the Croatian version of the NVS (NVS-HR) could be recommended for use in both clinical and research settings in Croatia.

PMID- 29447276 TI - Mesenchymal stem cell-derived exosomes have altered microRNA profiles and induce osteogenic differentiation depending on the stage of differentiation. AB - Human mesenchymal stem cell (hMSC)-derived exosomes have shown regenerative effects, but their role in osteogenesis and the underlying mechanism are yet to be determined. In this study, we examined the time-course secretion of exosomes by hMSCs during the entire process of osteogenic differentiation. Exosomes derived from hMSCs in various stages of osteogenic differentiation committed homotypic cells to differentiate towards osteogenic lineage, but only exosomes from late stages of osteogenic differentiation induced extracellular matrix mineralisation. Exosomes from expansion and early and late stages of osteogenic differentiation were internalised by a subpopulation of hMSCs. MicroRNA profiling revealed a set of differentially expressed exosomal microRNAs from the late stage of osteogenic differentiation, which were osteogenesis related. Target prediction demonstrated that these microRNAs enriched pathways involved in regulation of osteogenic differentiation and general mechanisms how exosomes exert their functions, such as "Wnt signalling pathway" and "endocytosis". Taken together, the results show that MSCs secrete exosomes with different biological properties depending on differentiation stage of their parent cells. The exosomal cargo transferred from MSCs in the late stage of differentiation induces osteogenic differentiation and mineralisation. Moreover, it is suggested that the regulatory effect on osteogenesis by exosomes is at least partly exerted by exosomal microRNA.

AB - BACKGROUND: Although investigations have shown that closing live poultry markets (LPMs) is highly effective in controlling human influenza A (H7N9) infections, many of the urban LPMs were shut down, but rural LPMs remained open. This study aimed to compare the proportional changes between urban and rural infections in the Zhejiang province from 2013 to 2017 by analyzing the exposure histories of human cases. METHODS: All laboratory-confirmed cases of H7N9 from 2013 (the first wave) to 2017 (the fifth wave) in the Zhejiang province of China were analyzed. Urban and rural infections were defined based on the locations of poultry exposure (direct and indirect) in urban areas (central towns) and rural areas (towns and villages on the outskirts of cities). A Chi-square trend test was used to compare the proportional trend between urban and rural infections over time and logistic regression was used to obtain the odds ratio by years. RESULTS: From 2013 to 2017, a statistically significant trend in rural infections was observed (p <0.01). The incremental odds ratio by years of rural infections was 1.59 with 95% confidence intervals of 1.34 to 1.86. Each year, significant increases in the proportion of live poultry transactions in LPMS and poultry processing plants were detected in conjunction with an increased proportion of urban and rural infections. CONCLUSION: The empirical evidence indicated a need for heightened infection control measures in rural areas, such as serving rural farms and backyards as active surveillance points for the H7N9 virus. Other potential interventions such as the vaccination of poultry and extending the closure of LPMs to the provincial level require further careful investigations.

AB - AIMS: Pattern-related visual stress (PRVS) refers to the perceptual difficulties experienced by some individuals when exposed to high contrast striped patterns. People with PRVS were reported to have reduced sensitivity to global motion at baseline testing and the difference disappears at a second estimate. The present study was to investigate the effect of practice on global motion threshold in adults with and without PRVS. METHODS: A total of 101 subjects were recruited and the Wilkins & Evans Pattern Glare Test was used to determine if a subject had PRVS. The threshold to detect global motion was measured with a random dot kinematogram. Each subject was measured 5 times at the first visit and again a month later. Receiver operating characteristic (ROC) curve analysis was applied to show the agreement between the two tests. RESULTS: Twenty-nine subjects were classified as having PRVS and 72 were classified as normal. At baseline, the threshold to detect global motion was significantly higher in subjects with PRVS (0.832 +/- 0.098 vs. 0.618 +/- 0.228, p < 0.001). After 5 sessions, the difference between the normal and subjects with PRVS increased (0.767 +/- 0.170 vs. 0.291 +/- 0.149, p < 0.001). In ROC analysis, the area under the curve (AUC) improved from 0.792 at baseline to 0.964 at the fifth session. After a one-month break, the difference between normal and subjects with PRVS was still significant (0.843 +/- 0.169 vs. 0.407 +/- 0.216, p < 0.001) and the AUC was 0.875. CONCLUSION: The ability to detect global motion is impaired in persons with PRVS and the difference increased after additional sessions of practice. PMID- 29447279 TI - Regulatory T cells in retroviral infections. AB - Tight regulation of immune responses is not only critical for preventing autoimmune diseases but also for preventing immunopathological damage during infections in which overactive immune responses may be more harmful for the host than the pathogen itself. Regulatory T cells (Tregs) play a critical role in this regulation, which was discovered using the Friend retrovirus (FV) mouse model. Subsequent FV studies revealed basic biological information about Tregs, including their suppressive activity on effector cells as well as the molecular mechanisms of virus-induced Treg expansion. Treg suppression not only limits immunopathology but also prevents complete elimination of pathogens contributing to chronic infections. Therefore, Tregs play a complex role in the pathogenesis of persistent retroviral infections. New therapeutic concepts to reactivate effector T-cell responses in chronic viral infections by manipulating Tregs also came from work with the FV model. This knowledge initiated many studies to characterize the role of Tregs in HIV pathogenesis in humans, where a complex picture is emerging. On one hand, Tregs suppress HIV-specific effector T-cell responses and are themselves targets of infection, but on the other hand, Tregs suppress HIV-induced immune hyperactivation and thus slow the infection of conventional CD4+ T cells and limit immunopathology. In this review, the basic findings from the FV mouse model are put into perspective with clinical and basic research from HIV studies. In addition, the few Treg studies performed in the simian immunodeficiency virus (SIV) monkey model will also be discussed. The review provides a comprehensive picture of the diverse role of Tregs in different retroviral infections and possible therapeutic approaches to treat retroviral chronicity and pathogenesis by manipulating Treg responses. PMID- 29447281 TI - Peptidic inhibitors of insulin-degrading enzyme with potential for dermatological applications discovered via phage display. AB - Insulin-degrading enzyme (IDE) is an atypical zinc-metalloendopeptidase that hydrolyzes insulin and other intermediate-sized peptide hormones, many of which are implicated in skin health and wound healing. Pharmacological inhibitors of IDE administered internally have been shown to slow the breakdown of insulin and thereby potentiate insulin action. Given the importance of insulin and other IDE substrates for a variety of dermatological processes, pharmacological inhibitors of IDE suitable for topical applications would be expected to hold significant therapeutic and cosmetic potential. Existing IDE inhibitors, however, are prohibitively expensive, difficult to synthesize and of undetermined toxicity. Here we used phage display to discover novel peptidic inhibitors of IDE, which were subsequently characterized in vitro and in cell culture assays. Among several peptide sequences tested, a cyclic dodecapeptide dubbed P12-3A was found to potently inhibit the degradation of insulin (Ki = 2.5 +/- 0.31 MUM) and other substrates by IDE, while also being resistant to degradation, stable in biological milieu, and highly selective for IDE. In cell culture, P12-3A was shown to potentiate several insulin-induced processes, including the transcription, translation and secretion of alpha-1 type I collagen in primary murine skin fibroblasts, and the migration of keratinocytes in a scratch wound migration assay. By virtue of its potency, stability, specificity for IDE, low cost of synthesis, and demonstrated ability to potentiate insulin-induced processes involved in wound healing and skin health, P12-3A holds significant therapeutic and cosmetic potential for topical applications. PMID- 29447282 TI - Addition of m6A to SV40 late mRNAs enhances viral structural gene expression and replication. AB - Polyomaviruses are a family of small DNA tumor viruses that includes several pathogenic human members, including Merkel cell polyomavirus, BK virus and JC virus. As is characteristic of DNA tumor viruses, gene expression in polyomaviruses is temporally regulated into an early phase, consisting of the viral regulatory proteins, and a late phase, consisting of the viral structural proteins. Previously, the late transcripts expressed by the prototypic polyomavirus simian virus 40 (SV40) were reported to contain several adenosines bearing methyl groups at the N6 position (m6A), although the precise location of these m6A residues, and their phenotypic effects, have not been investigated. Here, we first demonstrate that overexpression of the key m6A reader protein YTHDF2 induces more rapid viral replication, and larger viral plaques, in SV40 infected BSC40 cells, while mutational inactivation of the endogenous YTHDF2 gene, or the m6A methyltransferase METTL3, has the opposite effect, thus suggesting a positive role for m6A in the regulation of SV40 gene expression. To directly test this hypothesis, we mapped sites of m6A addition on SV40 transcripts and identified two m6A sites on the viral early transcripts and eleven m6A sites on the late mRNAs. Using synonymous mutations, we inactivated the majority of the m6A sites on the SV40 late mRNAs and observed that the resultant viral mutant replicated more slowly than wild type SV40. Alternative splicing of SV40 late mRNAs was unaffected by the reduction in m6A residues and our data instead suggest that m6A enhances the translation of viral late transcripts. Together, these data argue that the addition of m6A residues to the late transcripts encoded by SV40 plays an important role in enhancing viral gene expression and, hence, replication. PMID- 29447283 TI - Gp96 deficiency affects TLR4 functionality and impairs ERK and p38 phosphorylation. AB - Gp96 is an endoplasmic reticulum chaperone for multiple protein substrates. Its lack in intestinal macrophages of Crohn's disease (CD) patients is correlated with loss of tolerance against the host gut flora. Gp96 has been stablished to be an essential chaperone for Toll-like receptors (TLRs). We studied the impact of gp96-knockdown on TLR-function in macrophages. TLR2 and TLR4 expression was only decreased but not abolished when gp96 was knocked-down in cell lines, whereas in a monocyte/macrophage specific knock-out mouse model (LysMCre) TLR4 was abolished, while TLR2 was still present. Lipopolysaccharide (LPS)-induced NF kappaB activation was still observed in the absence of gp96, and gp96-deficient macrophages were able to up-regulate surface TLR4 upon LPS treatment, suggesting that there is another chaperone involved in the folding of TLR4 upon stress responses. Moreover, LPS-dependent pro-inflammatory cytokines were still expressed, although to a lesser extent in the absence of gp96, which reinforces the fact that gp96 is involved in regulating signaling cascades downstream of TLR4 are impaired upon loss of gp96. In addition, we have also found a reduced phosphorylation of ERK and p38 kinases and an impaired response upon CSF1R activation in gp96 deficient macrophages. Our findings indicate that the loss of gp96 not only impairs TLR4 signaling, but is also associated with a diminished phosphorylation of ERK and mitogen-activated stress kinases resulting in an impaired signalling through several receptors, including CSF1R.

AB - Lake Superior's ecosystem includes distinct nearshore and offshore food webs linked by hydrodynamic processes that transport water and tracers along and across shore. The scales over which these processes occur and their sensitivity to increasing summer surface temperatures are not well understood. This study investigated horizontal mixing between nearshore and offshore areas of Lake Superior over the 10-year period from 2003 to 2012 using a realistically forced three-dimensional numerical model and virtual tracers. An age tracer was used to characterize the time scales of horizontal mixing between nearshore areas of the lake where water depth is less than 100 m and deeper areas. The age of water in nearshore areas increased and decreased in an annual cycle corresponding to the lake's dimictic cycle of vertical mixing and stratification. Interannual variability of mixing in the isothermal period was significantly correlated to average springtime wind speed, whereas variability during the stratified season was correlated to the average summer surface temperature. Dispersal of a passive tracer released from nine locations around the model lake's perimeter was more extensive in late summer when stratification was established lakewide than in early summer. The distribution of eddies resolved in the model reflected differences between the early and late summer dispersal patterns. In the eastern part of the lake dispersal was primarily alongshore, reflecting counterclockwise coastal circulation. In the western part of the lake, cross-shore mixing was enhanced by cross-basin currents. PMID- 29447285 TI - Murine cytomegalovirus degrades MHC class II to colonize the salivary glands. AB - Cytomegaloviruses (CMVs) persistently and systemically infect the myeloid cells of immunocompetent hosts. Persistence implies immune evasion, and CMVs evade CD8+ T cells by inhibiting MHC class I-restricted antigen presentation. Myeloid cells can also interact with CD4+ T cells via MHC class II (MHC II). Human CMV (HCMV) attacks the MHC II presentation pathway in vitro, but what role this evasion might play in host colonization is unknown. We show that Murine CMV (MCMV) down regulates MHC II via M78, a multi-membrane spanning viral protein that captured MHC II from the cell surface and was necessary although not sufficient for its degradation in low pH endosomes. M78-deficient MCMV down-regulated MHC I but not MHC II. After intranasal inoculation, it showed a severe defect in salivary gland colonization that was associated with increased MHC II expression on infected cells, and was significantly rescued by CD4+ T cell loss. Therefore MCMV requires CD4+ T cell evasion by M78 to colonize the salivary glands, its main site of long term shedding. PMID- 29447284 TI - Influenza interaction with cocirculating pathogens and its impact on surveillance, pathogenesis, and epidemic profile: A key role for mathematical modelling. AB - Evidence is mounting that influenza virus interacts with other pathogens colonising or infecting the human respiratory tract. Taking into account interactions with other pathogens may be critical to determining the real influenza burden and the full impact of public health policies targeting influenza. This is particularly true for mathematical modelling studies, which have become critical in public health decision-making. Yet models usually focus on influenza virus acquisition and infection alone, thereby making broad oversimplifications of pathogen ecology. Herein, we report evidence of influenza virus interactions with bacteria and viruses and systematically review the modelling studies that have incorporated interactions. Despite the many studies examining possible associations between influenza and Streptococcus pneumoniae, Staphylococcus aureus, Haemophilus influenzae, Neisseria meningitidis, respiratory syncytial virus (RSV), human rhinoviruses, human parainfluenza viruses, etc., very few mathematical models have integrated other pathogens alongside influenza. The notable exception is the pneumococcus-influenza interaction, for which several recent modelling studies demonstrate the power of dynamic modelling as an approach to test biological hypotheses on interaction mechanisms and estimate the strength of those interactions. We explore how different interference mechanisms may lead to unexpected incidence trends and possible misinterpretation, and we illustrate the impact of interactions on public health surveillance using simple transmission models. We demonstrate that the development of multipathogen models is essential to assessing the true public health burden of influenza and that it is needed to help improve planning and evaluation of control measures. Finally, we identify the public health, surveillance, modelling, and biological challenges and propose avenues of research for the coming years.

AB - The Earth's climate is warming, especially in the mid- and high latitudes of the Northern Hemisphere. The northern elephant seal (Mirounga angustirostris) breeds and haul-outs on islands and the mainland of Baja California, Mexico, and California, U.S.A. At the beginning of the 21st century, numbers of elephant seals in California are increasing, but the status of Baja California populations is unknown, and some data suggest they may be decreasing. We hypothesize that the elephant seal population of Baja California is experiencing a decline because the animals are not migrating as far south due to warming sea and air temperatures. Here we assessed population trends of the Baja California population, and climate change in the region. The numbers of northern elephant seals in Baja California colonies have been decreasing since the 1990s, and both the surface waters off Baja California and the local air temperatures have warmed during the last three decades. We propose that declining population sizes may be attributable to decreased migration towards the southern portions of the range in response to the observed temperature increases. Further research is needed to confirm our hypothesis; however, if true, it would imply that elephant seal colonies of Baja California and California are not demographically isolated which would pose challenges to environmental and management policies between Mexico and the United States. PMID- 29447287 TI - Strain-specific quantification of root colonization by plant growth promoting rhizobacteria Bacillus firmus I-1582 and Bacillus amyloliquefaciens QST713 in non sterile soil and field conditions. AB - Bacillus amyloliquefaciens QST713 and B. firmus I-1582 are bacterial strains which are used as active ingredients of commercially-available soil application and seed treatment products Serenade(r) and VOTiVO(r), respectively. These bacteria colonize plant roots promoting plant growth and offering protection against pathogens/pests. The objective of this study was to develop a qPCR protocol to quantitate the dynamics of root colonization by these two strains under field conditions. Primers and TaqMan(r) probes were designed based on genome comparisons of the two strains with publicly-available and unpublished bacterial genomes of the same species. An optimized qPCR protocol was developed to quantify bacterial colonization of corn roots after seed treatment. Treated corn seeds were planted in non-sterile soil in the greenhouse and grown for 28 days. Specific detection of bacteria was quantified weekly, and showed stable colonization between ~104-105 CFU/g during the experimental period for both bacteria, and the protocol detected as low as 103 CFU/g bacteria on roots. In a separate experiment, streptomycin-resistant QST713 and rifampicin-resistant I 1582 strains were used to compare dilution-plating on TSA with the newly developed qPCR method. Results also indicated that the presence of natural microflora and another inoculated strain does not affect root colonization of either one of these strains. The same qPCR protocol was used to quantitate root colonization by QST713 and I-1582 in two corn and two soybean varieties grown in the field. Both bacteria were quantitated up to two weeks after seeds were planted in the field and there were no significant differences in root colonization in either bacteria strain among varieties. Results presented here confirm that the developed qPCR protocol can be successfully used to understand dynamics of root colonization by these bacteria in plants growing in growth chamber, greenhouse and the field. PMID- 29447289 TI - Correlates of self-harm and suicide attempts in justice-involved young people. AB - The purpose of this study was to ascertain the prevalence and correlates of self harm among young people in detention in Australia. The sample included 215 (177 male; 38 female) young people who were in youth detention in the state of Victoria, Australia. Participants were administered a series of questionnaires related to self-harm, mental health, socio-environmental experiences and behaviours. Overall, one-third (33%) of the sample reported previous self-harm and 12% reported at least one suicide attempt. In a multivariate logistic regression analysis, a history of childhood trauma, contact with mental health services, and low educational interest significantly increased the likelihood of self-harm. Young people who reported a suicide attempt scored significantly higher on the measure of childhood trauma than did youth who had engaged in non suicidal self-harm. Findings demonstrate a strong connection between childhood traumatic experiences and suicidal behaviours for youth in detention. Trauma histories and mental health concerns must be considered when identifying youth at increased risk of self-harm. PMID- 29447290 TI - A neonatal murine model for evaluation of enterovirus E HY12 virus infection and pathogenicity. AB - BACKGROUNDS: HY12 viruses are enteroviruses recently isolated from cattle characterized by severe respiratory and digestive disease with high morbidity and mortality in China. While the viruses exhibit unique biological and molecular characters distinct from known enterovirus E, the pathogenicity and viral pathogenesis remains largely unknown. METHODS: Neonatal mice of Balb/C, ICR, and Kunming strain are infected with HY12 to determine the susceptible mouse strain. The minimal infection dose, the virus infection routes, the pathogenicity and tissue tropism for HY12 were determined by infecting susceptible mice with HY12 viruses, and confirmed by different approaches including virus isolation and recovery, virus detection, histopathology, and immunohistochemistry. RESULTS: A murine model for HY12 infection was successfully established and employed to investigate the pathogenicity of HY12 viruses. ICR mouse strain is the most susceptible strain for HY12 infection with a minimal infective dose as 2*106TCID50/mouse. HY12 viruses have the capability of infecting ICR suckling mice via all infection routes including intranasal administration, oral administration, intraperitoneal injection, subcutaneous injection, and intramuscular injection, which are confirmed by the isolation and recovery of viruses from HY12-infected mice; detection of viruses by RT-PCR; observations of pathological lesions and inflammatory cell infiltrations in the intestine, lung, liver, and brain; uncovering of HY12 virus antigens in majority of tissues, especially in intestine, lung, and infected brain of mice by immunohistochemistry assay. CONCLUSIONS: A neonatal murine model for HY12 infection is successfully established for determining the susceptible mouse strain, the minimal infective dose, the infection route, the viral pathogenicity and the tropism of HY12, thus providing an invaluable model system for elucidating the pathogenesis of HY12 viruses and the elicited immunity.

PMID- 29447291 TI - Associations between physician home visits for the dying and place of death: A population-based retrospective cohort study. AB - BACKGROUND: While most individuals wish to die at home, the reality is that most will die in hospital. AIM: To determine whether receiving a physician home visit near the end-of-life is associated with lower odds of death in a hospital. DESIGN: Observational retrospective cohort study, examining location of death and health care in the last year of life. SETTING/PARTICIPANTS: Population-level study of Ontarians, a Canadian province with over 13 million residents. All decedents from April 1, 2010 to March 31, 2013 (n = 264,754). RESULTS: More than half of 264,754 decedents died in hospital: 45.7% died in an acute care hospital and 7.7% in complex continuing care. After adjustment for multiple factors including patient illness, home care services, and days of being at home receiving at least one physician home visit from a non-palliative care physician was associated with a 47% decreased odds (odds-ratio, 0.53; 95%CI: 0.51-0.55) of dying in a hospital. When a palliative care physician specialist was involved, the overall odds declined by 59% (odds ratio, 0.41; 95%CI: 0.39-0.43). The same model, adjusting for physician home visits, showed that receiving palliative home care was associated with a similar reduction (odds ratio, 0.49; 95%CI: 0.47 0.51). CONCLUSION: Location of death is strongly associated with end-of-life health care in the home. Less than one-third of the population, however, received end-of-life home care or a physician visit in their last year of life, revealing large room for improvement. PMID- 29447293 TI - The enzymatic processing of alpha-dystroglycan by MMP-2 is controlled by two anchoring sites distinct from the active site. AB - Dystroglycan (DG) is a membrane receptor, belonging to the dystrophin glycoprotein complex (DGC) and formed by two subunits, alpha-dystroglycan (alpha DG) and beta-dystroglycan (beta -DG). The C-terminal domain of alpha-DG and the N terminal extracellular domain of beta -DG are connected, providing a link between the extracellular matrix and the cytosol. Under pathological conditions, such as cancer and muscular dystrophies, DG may be the target of metalloproteinases MMP-2 and MMP-9, contributing to disease progression. Previously, we reported that the C-terminal domain alpha-DG (483-628) domain is particularly susceptible to the catalytic activity of MMP-2; here we show that the alpha-DG 621-628 region is required to carry out its complete digestion, suggesting that this portion may represent a MMP-2 anchoring site. Following this observation, we synthesized an alpha-DG based-peptide, spanning the (613-651) C-terminal region. The analysis of the kinetic and thermodynamic parameters of the whole and the isolated catalytic domain of MMP-2 (cdMMP-2) has shown its inhibitory properties, indicating the presence of (at least) two binding sites for the peptide, both located within the catalytic domain, only one of the two being topologically distinct from the catalytic active groove. However, the different behavior between whole MMP-2 and cdMMP-2 envisages the occurrence of an additional binding site for the peptide on the hemopexin-like domain of MMP-2. Interestingly, mass spectrometry analysis has shown that alpha-DG (613-651) peptide is cleavable even though it is a very poor substrate of MMP-2, a feature that renders this molecule a promising template for developing a selective MMP-2 inhibitor. PMID- 29447295 TI - Progress toward national estimates of police use of force. AB - This research builds on three decades of effort to produce national estimates of the amount and rate of force used by law enforcement officers in the United States. Prior efforts to produce national estimates have suffered from poor and inconsistent measurements of force, small and unrepresentative samples, low survey and/or item response rates, and disparate reporting of rates of force. The present study employs data from a nationally representative survey of state and local law enforcement agencies that has a high survey response rate as well as a relatively high rate of reporting uses of force. Using data on arrests for violent offenses and the number of sworn officers to impute missing data on uses of force, we estimate a total of 337,590 use of physical force incidents among State and local law enforcement agencies during 2012 with a 95 percent confidence interval of +/- 10,470 incidents or +/- 3.1 percent. This article reports the extent to which the number and rate of force incidents vary by the type and size of law enforcement agencies. Our findings demonstrate the willingness of a large proportion of law enforcement agencies to voluntarily report the amount of force used by their officers and the relative strengths and weaknesses of the Law Enforcement Management and Administrative Statistics (LEMAS) program to produce nationally representative information about police behavior. PMID- 29447294 TI - Evidence of sex-bias in gene expression in the brain transcriptome of two populations of rainbow trout (Oncorhynchus mykiss) with divergent life histories. AB - Sex-bias in gene expression is a mechanism that can generate phenotypic variance between the sexes, however, relatively little is known about how patterns of sex bias vary during development, and how variable sex-bias is between different populations. To that end, we measured sex-bias in gene expression in the brain transcriptome of rainbow trout (Oncorhynchus mykiss) during the first two years of development. Our sampling included from the fry stage through to when O. mykiss either migrate to the ocean or remain resident and undergo sexual maturation. Samples came from two F1 lines: One from migratory steelhead trout and one from resident rainbow trout. All samples were reared in a common garden environment and RNA sequencing (RNA-seq) was used to estimate patterns of gene expression. A total of 1,716 (4.6% of total) genes showed evidence of sex-bias in gene expression in at least one time point. The majority (96.7%) of sex-biased genes were differentially expressed during the second year of development, indicating that patterns of sex-bias in expression are tied to key developmental events, such as migration and sexual maturation. Mapping of differentially expressed genes to the O. mykiss genome revealed that the X chromosome is enriched for female upregulated genes, and this may indicate a lack of dosage compensation in rainbow trout. There were many more sex-biased genes in the migratory line than the resident line suggesting differences in patterns of gene expression in the brain between populations subjected to different forces of selection. Overall, our results suggest that there is considerable variation in the extent and identity of genes exhibiting sex-bias during the first two years of life. These differentially expressed genes may be connected to developmental differences between the sexes, and/or between adopting a resident or migratory life history.

PMID- 29447297 TI - Development of a decision aid for cardiopulmonary resuscitation and invasive mechanical ventilation in the intensive care unit employing user-centered design and a wiki platform for rapid prototyping. AB - BACKGROUND: Upon admission to an intensive care unit (ICU), all patients should discuss their goals of care and express their wishes concerning life-sustaining interventions (e.g., cardiopulmonary resuscitation (CPR)). Without such discussions, interventions that prolong life at the cost of decreasing its quality may be used without appropriate guidance from patients. OBJECTIVES: To adapt an existing decision aid about CPR to create a wiki-based decision aid individually adapted to each patient's risk factors; and to document the use of a wiki platform for this purpose. METHODS: We conducted three weeks of ethnographic observation in our ICU to observe intensivists and patients discussing goals of care and to identify their needs regarding decision making. We interviewed intensivists individually. Then we conducted three rounds of rapid prototyping involving 15 patients and 11 health professionals. We recorded and analyzed all discussions, interviews and comments, and collected sociodemographic data. Using a wiki, a website that allows multiple users to contribute or edit content, we adapted the decision aid accordingly and added the Good Outcome Following Attempted Resuscitation (GO-FAR) prediction rule calculator. RESULTS: We added discussion of invasive mechanical ventilation. The final decision aid comprises values clarification, risks and benefits of CPR and invasive mechanical ventilation, statistics about CPR, and a synthesis section. We added the GO-FAR prediction calculator as an online adjunct to the decision aid. Although three rounds of rapid prototyping simplified the information in the decision aid, 60% (n = 3/5) of the patients involved in the last cycle still did not understand its purpose. CONCLUSIONS: Wikis and user-centered design can be used to adapt decision aids to users' needs and local contexts. Our wiki platform allows other centers to adapt our tools, reducing duplication and accelerating scale-up. Physicians need training in shared decision making skills about goals of care and in using the decision aid. A video version of the decision aid could clarify its purpose. PMID- 29447298 TI - Effects of voluntary running exercise on bone histology in type 2 diabetic rats. AB - The incidence of obesity in children and adolescents, which may lead to type 2 diabetes, is increasing. Exercise is recommended to prevent and improve diabetes. However, little is known about the bone marrow environment at the onset of diabetes in the young, and it is unclear whether exercise training is useful for maintaining bone homeostasis, such as mechanical and histological properties. Thus, this study clarified the histological properties of bone and whether exercise contributes to maintaining bone homeostasis at the onset of type 2 diabetes in rats. Four-week-old male Otsuka Long-Evans Tokushima Fatty (OLETF; n = 21) rats as a diabetic model and Long-Evans Tokushima Otsuka (LETO; n = 18) rats as a control were assigned randomly to four groups: the OLETF sedentary group (O-Sed; n = 11), OLETF exercise group (O-Ex; n = 10), LETO sedentary group (L-Sed; n = 9), and LETO exercise group (L-Ex; n = 9). All rats in the exercise group were allowed free access to a steel running wheel for 20 weeks (5-25 weeks of age). In the glucose tolerance test, blood glucose level was higher in the O Sed group than that in the L-Sed and L-Ex groups, and was markedly suppressed by the voluntary running exercise of O-Ex rats. The energy to fracture and the two dimensional bone volume at 25 weeks of age did not differ significantly among the groups, though the maximum breaking force and stiffness were lower in OLETF rats. However, bone marrow fat volume was greater in O-Sed than that in L-Sed and L-Ex rats, and was markedly suppressed by wheel running in the O-Ex rats. Our results indicate that exercise has beneficial effects not only for preventing diabetes but also on normal bone remodeling at an early age. PMID- 29447299 TI - Effects of breast stimulation for spontaneous onset of labor on salivary oxytocin levels in low-risk pregnant women: A feasibility study. AB - OBJECTIVES: This preliminary study aimed to 1) determine changes in the salivary oxytocin (OT) level during breast stimulation for promoting the spontaneous onset of labor in low-risk term pregnancies, and 2) clarify the feasibility of the breast stimulation intervention protocol in terms of practicality and acceptability. METHODS: We used a single arm trial design. Sixteen low-risk pregnant women between 38 and 40 weeks of gestation with cephalic presentation participated. They performed breast stimulation for 3 days with an attendant midwife in a single maternity hospital. Each breast was stimulated for 15 minutes for a total of 1 hour per day. Saliva was collected 10 minutes before the intervention and 15, 30, 60, 75, and 90 minutes after the intervention, yielding 18 samples per woman. RESULTS: Among a total of 282 saliva samples from the 16 participants, OT level was measured in 142 samples (missing rate: 49.6%). The median OT level showed the highest values on day 3 of the breast stimulation, with a marked increase 30 min after the intervention. In the mixed models after multiple imputation for missing data, the OT level on the first day of intervention was significantly lower than that on the third day of intervention. Fatigue from breast stimulation decreased on subsequent days, and most of the women (75%) felt no discomfort with the protocol. Uterine hyperstimulation was not observed. CONCLUSION: Following a 3-day breast stimulation protocol for spontaneous onset of labor, the mean OT level showed the highest values on day 3. The breast stimulation intervention protocol showed good feasibility in terms of practicality and acceptability among the pregnant women. Additional large-scale studies are warranted to confirm the protocol's effectiveness. PMID- 29447300 TI - Explaining suicide attempt with personality traits of aggression and impulsivity in a high risk tribal population of India. AB - INTRODUCTION: Suicide is a spectrum of behavior including suicide ideation and suicidal attempt and is undoubtedly the outcome of the interaction of several factors. The role of two main constructs of human nature, aggression and impulsivity, has been discussed broadly in relation to suicide, as endophenotypes or traits of personality, in research and in clinical practice across diagnoses. The objective of our study was to assess impulsive and aggressive behaviors among primitive people of the Idu Mishmi tribe, who are known for high suicide completer and attempter rates. METHODS: The study group was comprised of 177 unrelated Idu Mishmi participants divided into two sets: 39 suicide attempters and 138 non-attempters. Data on demographic factors and details of suicide attempts were collected. Participants completed a set of instruments for assessment of aggression and impulsivity traits. RESULTS: In the Idu Mishimi population we screened (n = 177), 22.03% of the individuals had attempted suicide, a high percentage. The suicide attempters also showed a significant sex difference: 35.9% were male and 64.10% were female (p = .002*). The suicide attempters (A) scored significantly higher than non-attempters (NA) on aggression (A = 23.93,NA = 18.46) and impulsivity (A = 75.53,NA = 71.59, with p value = 0.05). The trait impulsiveness showed a significantly higher difference (F (1, 117) = 7.274) in comparison to aggression (F (1, 117) = 2.647), suggesting a profound role of impulsiveness in suicide attempts in the Idu Mishmi population. Analysis of sub-traits of aggression and impulsivity revealed significant correlations between them. Using different models, multivariate logistic regression implied roles of gender (OR = 1.079 (0.05)) and impulsiveness (OR = 3.355 (0.013)) in suicide attempts. CONCLUSION: Results demonstrate that gender and impulsivity are strong risk factors for suicide attempts in the Idu Mishmi population. PMID- 29447302 TI - In Throwers With Posterior Instability, Rotator Cuff Tears Are Common but Do Not Affect Surgical Outcomes. AB - In a previous study, compared with throwing athletes with superior labral anterior posterior (SLAP) tears, those with concomitant SLAP tears and rotator cuff tears (RCTs) had significantly poorer outcome scores and return to play. Posterior shoulder instability also occurs in throwing athletes, but no studies currently exist regarding outcomes of these patients with concomitant RCTs. The authors hypothesized that throwing athletes treated with arthroscopic capsulolabral repair for posterior shoulder instability with coexistent rotator cuff pathology would have poorer outcome scores and return to play. Fifty-six consecutive throwing athletes with unidirectional posterior shoulder instability underwent arthroscopic capsulolabral repair. Preoperative and postoperative patient-centered outcomes of pain, stability, function, range of motion, strength, and American Shoulder and Elbow Surgeons Shoulder (ASES) scores, as well as return to play, were evaluated. Patients with and without rotator cuff pathology were compared. Forty-three percent (24/56) of throwing athletes had rotator cuff pathology in addition to posterior capsulolabral pathology. All RCTs were debrided. At a mean of 3 years, there were no differences in preoperative and postoperative patient-centered outcomes between those with and without RCTs. Return-to-play rates showed no between-group differences; 92% (22/24) of athletes with concomitant RCTs returned to sport (P = .414), and 67% (16/24) returned to the same level (P = .430). Arthroscopic capsulolabral reconstruction is successful in throwing athletes with RCTs treated with arthroscopic debridement. Unlike the previous study evaluating throwers outcomes after surgical treatment for concomitant SLAP tears and RCTs, the authors found no difference in patient reported outcome measures or return to play for throwing athletes with concomitant posterior shoulder instability and RCTs. In throwing athletes with concomitant posterior instability and RCTs, arthroscopic posterior capsulolabral repair with rotator cuff debridement is successful. PMID- 29447303 TI - Arthroscopic Anterior Ankle Decompression Is Successful in National Football League Players. AB - Anterior ankle impingement is a frequent cause of pain and disability in athletes with impingement of soft-tissue or osseous structures along the anterior margin of the tibiotalar joint during dorsiflexion. In this study, we hypothesized that arthroscopic decompression of anterior ankle impingement would result in significant, reliable, and durable improvement in pain and range of motion (ROM), and would allow National Football League (NFL) players to return to their preoperative level of play. We reviewed 29 arthroscopic ankle debridements performed by a single surgeon. Each NFL player underwent arthroscopic debridement of pathologic soft tissue and of tibial and talar osteophytes in the anterior ankle. Preoperative and postoperative visual analog scale (VAS) pain scores, American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot scores, and ankle ROM were compared; time to return to play (RTP), events missed secondary to surgery, and complications were recorded. All athletes returned to the same level of NFL play at a mean (SD) of 8.4 (4.1) weeks after surgery and continued playing for a mean (SD) of 3.43 (2.57) years after surgery. Mean (SD) VAS pain scores decreased significantly (P < .001), to 0.38 (0.89) from 4.21 (1.52). Mean (SD) active ankle dorsiflexion increased significantly (P < .001), to 18.86 degrees (2.62 degrees ) from 8.28 degrees (4.14 degrees ). Mean (SD) AOFAS hindfoot scores increased significantly (P < .001), to 97.45 (4.72) from 70.62 (10.39). Degree of arthritis (r = 0.305) and age (r = 0.106) were poorly correlated to time to RTP. In all cases, arthroscopic debridement of anterior ankle impingement resulted in RTP at the same level at a mean of 2 months after surgery. There were significant improvements in VAS pain scores, AOFAS hindfoot scores, and ROM. Arthroscopic debridement of anterior ankle impingement relieves pain, restores ROM and function, and results in reliable RTP in professional football players.

PMID- 29447305 TI - Pseudo-Pedicle Heterotopic Ossification From Use of Recombinant Human Bone Morphogenetic Protein 2 (rhBMP-2) in Transforaminal Lumbar Interbody Fusion Cages. AB - We conducted a study to determine the common characteristics of patients who developed radiculopathy symptoms and corresponding heterotopic ossification (HO) from transforaminal lumbar interbody fusions (TLIF) using recombinant human bone morphogenetic protein 2 (rhBMP-2). HO can arise from a disk space with rhBMP-2 use in TLIF. Formation of bone around nerve roots or the thecal sac can cause a radiculopathy with a consistent pattern of symptoms. We identified 38 patients (26 males, 12 females) with a mean (SD) age of 50.8 (7.5) years who developed radiculopathy symptoms and corresponding HO from TLIF with rhBMP-2 in the disk space between 2002 and 2015. To document this complication and improve its recognition, we recorded common patterns of symptom development and radiologic findings: specifically, time from implantation of rhBMP-2 to symptom development, consistency with side of TLIF placement, and radiologic findings. Radicular pain generally developed a mean (SD) of 3.8 (1.0) months after TLIF with rhBMP-2. Development of radiculopathy symptoms corresponded to consistent "pseudo-pedicle" like HO. In all 38 patients, HO arising from the annulotomy site showed a distinct pseudo-pedicle pattern encompassing nerve roots and the thecal sac. In addition, development of radiculopathy symptoms and corresponding HO appear to be independent of amount of rhBMP-2. HO resulting from TLIF with rhBMP-2 in the disk space is a pain generator and a recognizable complication that can be diagnosed by assessment of symptoms and computed tomography characteristics. PMID- 29447301 TI - Esophageal squamous cell carcinoma with low mitochondrial copy number has mesenchymal and stem-like characteristics, and contributes to poor prognosis. AB - Alterations in mitochondrial DNA (mtDNA) copy numbers in various human cancers have been studied, but any such changes in esophageal squamous cell carcinoma (ESCC) are not established. In the present study, we investigated the correlation of mtDNA copy number with clinicopathologic features, prognosis, and malignant potential of ESCC. MtDNA copy numbers of resected specimens from 80 patients treated with radical esophagectomy were measured by quantitative real-time PCR analyses. Human ESCC cells, TE8 and TE11, were cultured, and depletion of mtDNA content was induced by knockdown of mitochondrial transcription factor A expression or treatment with ethidium bromide. The mRNA and protein expression, proliferation, invasion, and cell cycle were investigated. The results showed that the mtDNA copy number of cancerous portions was 56.0 (37.4-234.5) percent that of non-cancerous parts and significantly lower (p<0.01). Low mtDNA copy number in resected cancerous tissues was significantly correlated with pathological depth of tumor invasion (p = 0.045) and pathological stage (p = 0.025). Patients with lower mtDNA copy number had significantly poorer 5-year overall survival compared to patients with higher levels (p<0.01). The mtDNA depleted TE8 and TE11 cells had morphological changes and proliferated more slowly than control cells under normoxia but proliferated at almost the same rate under hypoxic conditions. In mtDNA-depleted cells, E-cadherin mRNA expression was decreased, and N-cadherin, vimentin, zeb-1, and cd44 mRNA expression was increased. Immunoblotting and flow cytometry analysis also showed downregulated E cadherin and upregulated N-cadherin and CD44 protein in mtDNA-depleted cells. Moreover, mtDNA-depleted cells had enhanced invasion, migration, and sphere formation abilities, and the cell cycle arrest at G0/G1 phase was induced in these cells. These results suggested that mtDNA-depleted ESCC cells had mesenchymal characteristics, cancer stemness, and tolerance to hypoxia, which played important role in cancer progression. In conclusion, a low copy number of mtDNA is associated with tumor progression in ESCC. PMID- 29447306 TI - Knotless Tape Suture Fixation of Quadriceps Tendon Rupture: A Novel Technique. AB - Quadriceps tendon ruptures disrupt the extensor mechanism of the knee and require urgent surgical management. Traditional repair techniques have had mixed biomechanical and clinical results risking weakness and extensor lag. We describe a novel technique using tape suture and knotless anchors, which has performed superiorly during biomechanical testing and yielded terrific early clinical results. PMID- 29447307 TI - Clinical and Histologic Evaluations of Immediately Placed SLA Dental Implants. AB - The goal of this investigation was to evaluate the bone-to-implant contact (BIC) of dental implants placed into fresh extraction sockets without pre-existing periapical pathology. When the extraction sites exhibited a gap distance of > 2 mm, autogenous bone harvested from surrounding surgical sites was grafted to fill that gap with no barrier membranes. All implants were clinically stable and successful at 6 months postoperative. The histologic examination demonstrated an average of 66.2% BIC for all five immediately placed dental implants. The results of this study provided sufficient histologic and histomorphometric knowledge to support immediate dental implant placement in carefully selected clinical scenarios. PMID- 29447308 TI - Simplified Protocol for Relining Provisional Prosthesis on Natural Abutments: A Technical Note. AB - This article describes a simplified technique for relining provisional prostheses on natural abutments that can be applied to this specific type of tooth preparation with feather-edge finish line. Starting from a diagnostic wax-up, a provisional fixed restoration is constructed, containing all the correct structural information. This includes the controlled depth of the prosthetic margin into the gingival sulcus, the emergence profile, and the area from the emergence profile to the gingival third. Chair time is saved during the clinical procedures because the finishing and polishing steps are shortened, and the resulting provisional restoration is precise and highly biocompatible. This technique allows for a simple and quick relining and finishing procedure and for the delivery of an esthetic and biocompatible provisional restoration. PMID- 29447309 TI - Single-Tooth Replacement Using Dental Implants Supporting All-Ceramic and Metal Based Reconstructions: Results at 18 Months of Loading. AB - The aim of this study was to compare customized zirconia and titanium abutments with respect to survival rates and technical, biologic, and esthetic outcomes. A total of 28 patients with single implants were randomly assigned to 12 customized zirconia (test, AC) and 16 customized titanium (control, MC) abutments. Technical, biologic, and esthetic outcomes were assessed after a mean follow-up time of 18 months. No biologic complications were observed, and no statistical difference for the bone-to-implant distance was found at 18 months (AC -0.05 +/- 0.51 mm vs MC -0.28 +/- 0.77 mm; P = .40). A similar discoloration of the peri implant mucosa was observed (DeltaEAC 9.6 +/- 5.4, DeltaEMC 7.6 +/- 5.3; P = .46). The mean papilla score values evaluation presented no statistically significant differences between the test and control groups (AC 2.07 +/- 0.94, MC 1.96 +/- 0.84). At 18 months, reconstructions based on zirconia and titanium abutments exhibited similar survival rates and similar clinical outcomes. PMID- 29447310 TI - Retrospective Evaluation of Factors Related to the Outcomes of Regenerative Therapy for Implants Affected by Peri-implantitis. AB - The aim of this retrospective study was to examine the histories of 100 patients with 170 implants that were consecutively treated and reported in a previous study to identify which patient and implant factors might have affected the outcomes of therapy. Patient factors included history of periodontitis, hypertension, cardiac problems, rheumatoid arthritis, smoking, and penicillin allergy. Implant factors included whether the prosthesis was cemented or screw retained and initial bone loss (<= 50% or > 50% of implant length). Frequency of maintenance visits (<= 3 months or > 3 months) were recorded, as was patient age (<= 60 years or > 60 years). On the patient level, only postoperative maintenance (<= 3 months) showed a statistically significant effect on radiographic bone gain (RBG) compared to patients with > 3 months maintenance frequency. Nondiabetic patients showed a trend toward soft tissue gain. On an implant level, screw retained prostheses demonstrated a statistically significant RBG compared to those with cement-retained prostheses. Significant favorable differences were seen in all outcomes when evaluating presurgical bone level loss (> 50% of the implant length). Further studies with larger groups of patients are necessary to substantiate the findings in this report. PMID- 29447311 TI - A Simplified Approach for Restoration of Worn Dentition Using the Full Mock-up Concept: Clinical Case Reports. AB - Treatment of tooth wear has increased over the last two decades. However, the treatments involved have not been satisfactory to most patients, nor have they achieved the expected goal on some worn teeth. New approaches have emerged to reconstruct full arches in a minimally invasive way that take advantage of developments in the field of adhesive dentistry. These new concepts constitute a revolution in dentistry and their application requires adapted techniques and training. The purpose of this article is to suggest a precise and reproducible method that simplifies the treatment of worn dentition. A wax-up and a mock-up are primarily used to design the esthetic outcome and then used as a guide for the preparation of anterior teeth or the occlusal surfaces of posterior teeth. This not only provides the exact new vertical dimension of occlusion but serves as a guide for precisely controlling occlusal preparation simultaneously with buccal preparation. The classical cavity design for a partial bonded restoration on posterior worn dentition is also reviewed. The authors believe that during the preparation of the occlusal surfaces of the posterior teeth surfaces, the marginal ridges must be preserved to reduce the biologic cost and mechanical stress leading to fracture. A new type of thin and reduced restoration called tabletop is presented. PMID- 29447312 TI - The Bone Core Technique for the Augmentation of Limited Bony Defects: Five-Year Prospective Study with a New Minimally Invasive Technique. AB - The aim of this study was to evaluate a new minimally invasive surgical technique for the reconstruction of critical-size bony defect with local harvested bone core with simultaneous implant placement. In a prospective study, 186 consecutively treated patients were included and controlled clinically and radiologically for at least 5 years postoperative. Every patient presented a bony defect affecting the buccal, lingual, or palatal wall. In all cases, the alveolar crest was wide enough to allow implant placement inside the bony contours. During implant bed preparation, a trephine bur (3.5 mm external diameter and 2.5 mm internal diameter) was used to harvest a bone core from the socket. After implant insertion, the buccal/palatal/lingual bony defect was grafted with bone chips covered with the bone core stabilized through compression with microscrews. After 3 months of healing, the implants and the grafted bone were exposed and the width of the grafted area was measured. After prosthetic restoration, the patients were recalled regularly. A total of 223 grafted sites were documented. Minor primary healing complications were observed in 3 sites (1.4%), all in smoker patients, and were treated locally without any influence on the prognosis. All other sites healed uneventfully. In 19 cases (4.4%), exposure of the screw heads was detected 1 to 3 months postoperatively without any inflammation or consequences for the grafted bone. The average width of the reconstructed area at the end of the grafting procedure was 2.4 +/- 0.8 mm, and at the reentry, 2.1 +/- 0.6 mm. There was a difference of remodeling between bone cores grafted totally inside or partially outside the bony contours. Bone cores grafted completely inside the bony contours demonstrated no resorption at 3 months postoperative, while bone cores grafted partially outside the bony contours in most cases showed partial resorption of the bone outside the bony contours. After 3 months of healing, all 223 implants had achieved primary healing and osseointegration and were restored after an average time of 4 months. No implant failed during the control period. According to this study, the use of an autogenous bone core harvested during the implant bed preparation is a simple and safe method for the reconstruction of small bone defects. PMID- 29447313 TI - Double Duplicate Technique for CAD/CAM Full-Arch Immediate Loading: A Technical Description and Case Report. AB - Full-arch fixed implant-supported prostheses have shown high biologic success rates after long-term follow-up, along with technical and prosthetic complications. Adequate planning is necessary for immediate implant occlusal loading in a completely edentulous maxilla or mandible. For totally edentulous patients, the main prosthetic problem is the transfer of diagnostic information to the master cast when an immediate loading approach is used. The aim of this clinical case report is to illustrate a new prosthetic protocol for immediate implant loading in edentulous or potentially edentulous patients. This innovative procedure can successfully guide the clinician step by step in a predictable way from diagnosis to delivery of an immediately loaded implant-supported full-arch rehabilitation. PMID- 29447314 TI - Restoration of Periodontally Compromised Dentitions Using Telescopic Full-Arch Retrievable Prosthesis Supported by Tooth-Implant Combination: A Long-Term Retrospective Study. AB - Advanced periodontal disease is often associated with severe loss of tooth support, necessitating prosthetic rehabilitation to restore function and esthetics. For tooth-supported restorations, periodontally compromised teeth may need to be extracted due to early failure from functional overload. For tooth/implant-supported restorations, implants can be used to reduce the overload on teeth and to avoid tooth extraction, bone augmentation, or other risks associated with implant placement. The aim of this retrospective study was to evaluate the long-term outcomes of full-arch, retrievable, telescopic-retained prostheses (TRPs) on teeth and implants according to survival rate analyses and technical and biologic complications in full-mouth rehabilitation of periodontally compromised dentitions. A total of 18 periodontally compromised patients (7 women, 11 men) with a mean age of 46.8 years (SD: 6.3 years; range: 32 to 64 years) were selected to receive supplementary implants with the aim of extensive prosthetic support in combined tooth/implant TRPs and annually evaluated for technical and/or biologic failures/complications. After a follow-up period of 15 years, all prostheses were in function. Complication rates were low, and maintenance services were limited to minor interventions. Combined tooth/implant TRPs improve prosthetic support and offer successful function over the long term in patients with periodontally compromised dentition.

AB - This report describes a failed blade implant after 25 years in function in the left maxilla and the results of histologic analysis of peri-implant tissues. The blade was retrieved, and histologic findings revealed that it was not osseointegrated despite being successfully in function for so many years. The long-term function of blade implants without osseointegration can be attributed to biotolerance exhibited by the implant rather than actual osseointegration. PMID- 29447316 TI - Peri-Implant Mucosal Creeping: Two Case Reports. AB - While creeping attachment in natural teeth has been reported in the literature for decades, the same phenomenon around dental implants is a new concept. This article describes two implant cases treated with free gingival autograft with follow-up at 18 and 30 months. Progressive coronal creeping of the mucosal margin was observed covering the implant and abutment surfaces postoperatively. This report demonstrates that mucosal creeping around implants may occur after peri implant plastic surgical procedures, further improving the final outcomes of therapy. PMID- 29447317 TI - Evaluation of Bone Stability and Esthetic Results After Immediate Implant Placement Using a Novel Synthetic Bone Substitute in the Anterior Zone: Results After 12 Months. AB - The aim of this study was to assess bone and soft tissue changes after tooth extraction and immediate implant insertion in the anterior maxilla. A novel synthetic bone graft (VivOss, Straumann) was used to fill the gap between the implant surface and the alveolar bone. Implants with a reduced diameter compared to the size of the socket were used. A fixed or removable provisional restoration was provided immediately after implant placement. Cone beam computed tomography (CBCT) scans were taken to evaluate bone changes, showing minor variations after 12 months of follow-up. To evaluate soft tissue changes, clinical vertical measurements were performed. Based on the results obtained from 15 implants placed in 14 patients, it can be concluded that the use of an immediate implant in combination with a synthetic bone graft and immediate provisionalization seems to be a predictable treatment option with satisfactory esthetic results after 1 year. PMID- 29447318 TI - Management of Multiple Gingival Recessions with the VISTA Technique: An 18-Month Clinical Case Series. AB - The purpose of the present study was to evaluate the efficacy of the vestibular incision subperiosteal tunnel access (VISTA) technique with collagen membrane, bioactive glass, and platelet-rich fibrin. A total of 22 systemically and periodontally healthy subjects with multiple gingival recession defects (Miller Class I and II) in the maxillary esthetic zone were enrolled in the study. The primary outcome measures were mean root coverage and alteration in gingival thickness. There were no surgical complications; however, one patient reported swelling of the upper lip area on the first postoperative day, which resolved spontaneously. A statistically significant increase in gingival thickness (0.45 mm) and 94.17% +/- 8.42% mean root coverage was observed at 18 months. Within the limitations of this study, it was concluded that the VISTA technique augmented with collagen membrane, bioactive glass, and platelet-rich fibrin is a predictable modality in multiple recession management. PMID- 29447319 TI - Squamous Cell Carcinoma of the Gingiva Mimicking Periodontal Disease: A Diagnostic Challenge and Therapeutic Dilemma. AB - A case of squamous cell carcinoma of the gingiva (GSCC) in the left anterior maxilla in a 64-year-old woman that was treated for almost 5 years as suspected periodontal lesion prior to establishing the final diagnosis of oral cancer is presented in this case report. GSCCs have a variable clinical appearance, ranging from an exophytic mass to ulcerative lesions. They have been reported to pose a diagnostic challenge and are not infrequently initially misdiagnosed as periodontal disease. A delay in diagnosis and extraction of teeth in the vicinity of GSCCs has been demonstrated to increase the risk for lymph node metastasis and thus result in a lower 5-year survival rate. To avoid misdiagnosis and delay of the appropriate treatment, a proper histopathologic evaluation is mandatory whenever an incisional biopsy is performed. Furthermore, referral to a specialist in oral medicine or oral and maxillofacial surgery is indicated when a gingival lesion is nonresponsive to treatment, recurring, or rapidly growing in size. PMID- 29447320 TI - A Pilot Study on the Efficacy of a Treatment Algorithm to Detoxify Dental Implant Surfaces Affected by Peri-implantitis. AB - This in vitro pilot study was performed to determine whether a treatment algorithm including mechanical debridement, followed by air powder abrasion with glycine, followed by citric acid conditioning with vigorous flushing of the surface with sterile water after each step, is capable of decontaminating an infected implant surface. A total of 14 dental implants that were deemed hopeless due to advanced peri-implantitis were extracted. Of these, 6 implants served as tests and had their exposed surfaces treated with the decontamination protocol, 6 served as untreated controls, and 2 were mechanically treated only, followed by rubbing the surface with sterile saline. All implants were placed in culture with human osteoprogenitor cells for 72 hours, and evaluation was performed using scanning electron microscopy. The 6 test implants all demonstrated attachment and proliferation of the normal human osteoprogenitor cells on their prior exposed and decontaminated surfaces. All of the untreated control and the mechanically debrided, sterile water-treated implants failed to demonstrate this same success. The results suggest that this protocol can decontaminate an implant surface affected by peri-implantitis. Further studies are warranted to determine if this technique would demonstrate similar success over a greater number of implants and whether this outcome may occur in humans. PMID- 29447321 TI - Decision Tree for Vertical Ridge Augmentation. AB - Vertical ridge augmentation (VRA) procedures before or during dental implant placement are technically challenging and often encounter procedure-related complications. To minimize complications and promote success, a literature search was conducted to validate procedures used for VRA. A decision tree based on the amount of additional ridge height needed (< 4, 4 to 6, or > 6 mm) was then developed to improve the procedure-selection process. At each junction, the clinician is urged to consider anatomical, clinical, and patient-related factors influencing treatment outcomes. This decision tree guides selection of the most appropriate treatment modality and sequence for safe, predictable management of the vertically deficient ridge in implant therapy.

AB - The conometric retention system was proposed and described as a predictable alternative to retain fixed implant-supported complete dentures and, more recently, to retain fixed partial restorations. Currently available studies describe a technique based on the Ankylos (Dentsply) implant system and stock conic coupling abutments. The purpose of this case series study is therefore to demonstrate the possibility of using Atlantis computer-aided design/computer assisted manufacture technology to produce Conus abutments (Dentsply) and using the fixed conometric retention with other implant brands for which appropriate stock conic coupling abutments are not available.

AB - The aim of the present survey was to define the most appropriate recall regimen and professional maintenance care protocol, identifying the main relative issues, based on a consensus of experts with long-term clinical experience. The survey consisted of 14 clinically relevant focused questions. The answers of each expert were aggregated to formulate clinical recommendations. The maintenance care protocol must be individually determined and a baseline condition identified. The recall frequency must have a specific periodicity, and bone levels must be radiographically checked at least every 2 years, unless specific needs require a shorter interval. PMID- 29447324 TI - Accuracy and Usefulness of CBCT in Periodontology: A Systematic Review of the Literature. AB - A systematic literature review was performed regarding the accuracy and usefulness of cone beam computed tomography (CBCT) in the field of periodontology. A total of 580 articles were identified, of which 13 met the inclusion criteria. Results showed a high accuracy of CBCT in visualizing periodontal structures and the demonstrated the usefulness of CBCT in regenerative periodontal surgery of maxillary molars. It remains questionable whether this gain of additional information actually leads to a better clinical outcome in periodontal treatment. Currently, the use of CBCT in periodontology should be restricted to complex periodontal cases, particularly those involving maxillary molars. PMID- 29447325 TI - Long-term results after restoring nasal tip support using auricular cartilage as an intercrural columellar strut graft: the "I-Beam" technique. AB - BACKGROUND: The lack of nasal tip support resulting in poor protection and projection of the nose is a common cause of nasal obstruction and cosmetic impairment. Although septal cartilage is preferred for restoration of nasal tip support, there is often not enough septal cartilage available. We describe an intercrural columellar strut graft in a circumferential soft tissue pocket: the I Beam technique. METHODOLOGY: In this cohort study over an 8-year period the clinical and biometrical long-term results after restoration of nasal tip support with an autologous auricular cartilage graft, the I-Beam technique, is evaluated. RESULTS: Out of the 72 consecutive septorhinoplasties with the I-Beam technique, we studied 66 patients in the median long-term follow-up of 89 months. In all patients a significant improvement in nasal tip projection was found. A functional improvement in nasal breathing was achieved in 86%. The overall satisfaction with the I-Beam graft was of 83%. No deterioration in smell perception was found after surgery. CONCLUSIONS: The I-Beam technique using back to-back sutured autologous auricular cartilage is a safe and effective technique and gives long-term structural support and enhances tip projection.

Our aim is to describe the sphenoid drill out technique as a sphenoid salvage intervention and to outline its implications on clinical outcome and quality of life. METHODOLOGY: 12 patients with chronic sphenoiditis undergoing a sphenoid drill out procedure were examined by nasal endoscopy preoperatively and postoperatively for one year. Preoperative and postoperative quality of life questionnaires (RSOM-31 and SF-36) were obtained. RESULTS: All but one patient had a completely patent neostium without scar formation. No major complications occurred after this procedure. All patients reported at least an improvement of their symptoms, 50% of patients were even symptom free at one year after surgery. The median postoperative RSOM-31 score was significantly lower than the preoperative score. Both the physical component summary (PCS) and the mental component summary (MCS) of the SF-36 score improved significantly. None of the patients needed a revision procedure. CONCLUSION: Sphenoid drill out is a safe and effective technique with a high success rate. In patients with chronic sphenoid sinusitis refractory to medical therapy and surgery it could be a valid alternative to revision sphenoidotomy. PMID- 29447327 TI - ? AB - BACKGROUND: The lack of nasal tip support resulting in poor protection and projection of the nose is a common cause of nasal obstruction and cosmetic impairment. Although septal cartilage is preferred for restoration of nasal tip support, there is often not enough septal cartilage available. We describe an intercrural columellar strut graft in a circumferential soft tissue pocket: the I Beam technique. METHODOLOGY: In this cohort study over an 8-year period the clinical and biometrical long-term results after restoration of nasal tip support with an autologous auricular cartilage graft, the I-Beam technique, is evaluated. RESULTS: Out of the 72 consecutive septorhinoplasties with the I-Beam technique, we studied 66 patients in the median long-term follow-up of 89 months. In all patients a significant improvement in nasal tip projection was found. A functional improvement in nasal breathing was achieved in 86%. The overall satisfaction with the I-Beam graft was of 83%. No deterioration in smell perception was found after surgery. CONCLUSIONS: The I-Beam technique using back to-back sutured autologous auricular cartilage is a safe and effective technique and gives long-term structural support and enhances tip projection. PMID- 29447328 TI - Cardiac surgery in adult patients with remitted or active malignancies: a review of preoperative screening, surgical management and short- and long-term postoperative results. AB - Candidate patients for cardiac surgery procedures with a history of malignancies and antitumour therapy or with an active cancer and on antineoplastic treatment are increasingly common in daily practice. Oncological therapy can lead to cardiovascular injury and, therefore, has the potential for impacting operative risks and surgical strategies. This means that a number of considerations are essential to take into account prior to cardiac surgery. These include the type of cancer, previous cardiotoxicity or concomitant antitumour therapy, reversibility or irreversibility of such complications, the interaction between cancer disease course and extracorporeal circulation, the need for associated surgery and the impact of cancer on early and long-term outcomes. Adequate preoperative evaluation of cardiovascular abnormalities potentially related to antineoplastic therapy and proper diagnostic workup of other conditions linked to the type of cancer (e.g. haematological disorders and lung dysfunction) are therefore of paramount importance for appropriate surgical decision-making. Careful evaluation of the association of cardiovascular disease to be treated and the prognosis of remitted or active cancer should be established to enhance the prediction of early, medium and long-term outcomes and for a more correctly informed patient. Furthermore, if the prognosis of operated patients appears unfavourable, then alternative therapeutic strategies can be applied without significant delay. The aim of this review is to give an overview of factors that should be considered in adult patients who are undergoing, or have undergone, treatment for oncological indications who are candidates for cardiac surgery. PMID- 29447329 TI - Randomised phase III trial of vinflunine plus capecitabine versus capecitabine alone in patients with advanced breast cancer previously treated with an anthracycline and resistant to taxane. AB - Background: Capecitabine is an approved standard therapy for anthracycline- and taxane-pretreated locally advanced or metastatic breast cancer (BC). Vinflunine has demonstrated single-agent activity in phase II studies in this setting and activity and tolerability when combined with capecitabine. We compared the combination of vinflunine plus capecitabine (VC) with single-agent capecitabine. Patients and methods: Patients with locally recurrent/metastatic BC previously treated or resistant to an anthracycline and resistant to taxane therapy were randomly assigned to either vinflunine (280 mg/m2, day 1) plus oral capecitabine [825 mg/m2 twice daily (b.i.d.), days 1-14] every 3 weeks (q3w) or single-agent oral capecitabine (1250 mg/m2 b.i.d., days 1-14) q3w. The primary end point was progression-free survival (PFS) assessed by an independent review committee. The study had 90% power to detect a 30% improvement in PFS. Results: Overall, 770 patients were randomised. PFS was significantly longer with VC than with capecitabine alone [hazard ratio, 0.84, 95% confidence interval (CI), 0.71-0.99; log-rank P = 0.043; median 5.6 versus 4.3 months, respectively]. Median overall survival was 13.9 versus 11.7 months with VC versus capecitabine alone, respectively (hazard ratio, 0.98; 95% CI, 0.83-1.15; log-rank P = 0.77). No difference in quality of life was observed between the two treatment arms. The most common adverse events (NCI CTCAE version 3.0) in the combination arm were haematological and gastrointestinal. Grade 4 neutropenia was more frequent with VC (12% versus 1% with capecitabine alone); febrile neutropenia occurred in 2% versus 0.5%, respectively. Hand-foot syndrome was less frequent with VC (grade 3: 4% versus 19% for capecitabine alone). Peripheral neuropathy was uncommon in both arms (grade 3: 1% versus 0.3%). Conclusions: Vinflunine combined with capecitabine demonstrated a modest improvement in PFS and an acceptable safety profile compared with capecitabine alone in patients with anthracycline- and taxane-pretreated locally recurrent/metastatic BC.

PMID- 29447330 TI - Is central lung tumour location really predictive for occult mediastinal nodal disease in (suspected) non-small-cell lung cancer staged cN0 on 18F fluorodeoxyglucose positron emission tomography-computed tomography? AB - OBJECTIVES: Current guidelines recommend preoperative invasive mediastinal staging in centrally located tumours with negative mediastinum on positron emission tomography-computed tomography, based on a 20-30% prevalence of occult mediastinal disease (pN2-3). However, a uniform definition of central tumour location is lacking. Our objective was to determine the best definition in predicting occult pN2-3. METHODS: A single-institution database was queried for patients with (suspected) non-small-cell lung cancer staged cN0 after positron emission tomography-computed tomography and referred to invasive staging and/or primary surgery. We evaluated 5 definitions: inner 1/3, inner 2/3, contact with bronchovascular structures, <=2 cm from bronchus or endobronchial visualization. RESULTS: Between 2005 and 2015, 813 patients were eligible (cT1: 42%, cT2: 28%, cT3: 17% and cT4: 11%). Invasive mediastinal staging and resection were performed in 30% and 97% of patients, respectively. Any nodal upstaging (pN+) was found in 21% of patients, of whom pN2-3 was found in 8%. Central tumour location demonstrated 4 times higher odds for any pN+ [for inner 1/3 vs outer 2/3, odds ratio 3.90 (95% confidence interval 2.24-6.77), P < 0.001], whereas no significantly different odds was observed for pN2-3. The discriminative ability for pN+ was not significantly different between the several definitions. CONCLUSIONS: The prevalence of occult pN2-3 was only 8% when modern fusion positron emission tomography-computed tomography imaging pointed at clinical N0 non-small-cell lung cancer. None of the 5 verified definitions of centrality was predictive for occult pN2-3. However, each definition of centrality was related to any pN+ at a prevalence of 21%, without significant differences in discriminative ability between definitions. These data question whether indication for preoperative invasive mediastinal staging should be based on centrality alone.

PMID- 29447332 TI - The impact of the maternal-foetal environment on outcomes of surgery for congenital heart disease in neonates. AB - OBJECTIVES: Pregnancies with congenital heart disease in the foetus have an increased prevalence of pre-eclampsia, small for gestational age and preterm birth, which are evidence of an impaired maternal-foetal environment (MFE). METHODS: The impact of an impaired MFE, defined as pre-eclampsia, small for gestational age or preterm birth, on outcomes after cardiac surgery was evaluated in neonates (n = 135) enrolled in a study evaluating exposure to environmental toxicants and neuro-developmental outcomes. RESULTS: The most common diagnoses were transposition of the great arteries (n = 47) and hypoplastic left heart syndrome (n = 43). Impaired MFE was present in 28 of 135 (21%) subjects, with small for gestational age present in 17 (61%) patients. The presence of an impaired MFE was similar for all diagnoses, except transposition of the great arteries (P < 0.006). Postoperative length of stay was shorter for subjects without an impaired MFE (14 vs 38 days, P < 0.001). Hospital mortality was not significantly different with or without impaired MFE (11.7% vs 2.8%, P = 0.104). However, for the entire cohort, survival at 36 months was greater for those without an impaired MFE (96% vs 68%, P = 0.001). For patients with hypoplastic left heart syndrome, survival was also greater for those without an impaired MFE (90% vs 43%, P = 0.007). CONCLUSIONS: An impaired MFE is common in pregnancies in which the foetus has congenital heart disease. After cardiac surgery in neonates, the presence of an impaired MFE was associated with lower survival at 36 months of age for the entire cohort and for the subgroup with hypoplastic left heart syndrome.

PMID- 29447337 TI - An analysis of patients requiring unifocalization revision following midline unifocalization for pulmonary atresia with ventricular septal defect and major aortopulmonary collaterals. AB - OBJECTIVES: Midline unifocalization has been developed for the surgical treatment of pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries. All patients will eventually require reoperation because of the presence of a conduit, and some patients may also require revision of the distal unifocalized bed. The purpose of this study was to analyse the need for unifocalization revision following midline unifocalization. METHODS: This was a retrospective review of 241 patients who underwent midline unifocalization for the treatment of pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries. Two hundred and four (85.4%) patients had a single-stage complete repair, whereas 37 patients had a unifocalization and placement of a central shunt. Seventy-eight patients have subsequently undergone reoperations at our institution, including 44 operations that required unifocalization revision. These 44 patients were compared with the 191 operative survivors who did not require revision. RESULTS: An analysis of risk factors for requiring unifocalization revision included the following: (i) single-stage complete repair versus unifocalization and shunt (14.7% vs 37.8%, P < 0.001), (ii) right ventricle to aortic pressure ratio at the initial repair (0.33 +/- 0.07 vs 0.44 +/- 0.08, P < 0.001) and (iii) absence of central pulmonary arteries (32.8% vs 13.4%, P < 0.001). CONCLUSIONS: Data demonstrate that 44 of 241 (18%) patients who underwent midline unifocalization have subsequently required revision of their unifocalization. The need for unifocalization revision was associated with 3 factors, all of which were known at the time of discharge from the initial unifocalization. These data suggest that potentially higher risk patients should be monitored more closely than their lower risk counterparts.

AB - Autoantibodies to aquaporin-4 (AQP4) are pathogenic in neuromyelitis optica spectrum disorder (NMOSD). However, it is not known which B cells are the major contributors to circulating AQP4 antibodies nor which conditions promote their generation. Our experiments showed CD19+CD27++CD38++ circulating ex vivo antibody secreting cells did not produce AQP4 antibodies under several culture conditions. To question whether other cells in circulation were capable of AQP4 antibody production, B cells were differentiated into antibody-secreting cells in vitro. Unfractionated peripheral blood mononuclear cells, isolated from 12 patients with NMOSD and a wide range of serum AQP4 antibody levels (91-26 610 units), were cultured with factors that mimicked established associations of NMOSD including T cell help, concurrent infections and cytokines reported to be elevated in NMOSD. Overall, the in vitro generation of CD19+CD27++CD38++ cells across several culture conditions correlated closely with the total IgG secreted (P < 0.0001, r = 0.71), but not the amount of AQP4 antibody. AQP4 antibody production was enhanced by CD40-ligand (P = 0.005), and by interleukin-2 plus toll-like receptor stimulation versus interleukin-21-predominant conditions (P < 0.0001), and did not require antigen. Across NMOSD patients, this in vitro generation of AQP4 antibodies correlated well with serum AQP4 antibody levels (P = 0.0023, r = 0.81). To understand how early within B cell lineages this AQP4 specificity was generated, purified B cell subsets were activated under these optimized conditions. Naive pre-germinal centre B cells (CD19+CD27-IgD+) differentiated to secrete AQP4 antibodies as frequently as post-germinal centre cells (CD19+CD27+). Taken together, these human cell-culture experiments demonstrate that preformed B cells, rather than ex vivo circulating antibody-secreting cells, possess AQP4 reactivity. Their differentiation and AQP4 antibody secretion is preferentially driven by select cytokines and these cells may make the dominant contribution to serum AQP4 antibodies. Furthermore, as AQP4-specific B cells can derive from likely autoreactive naive populations an early, pre-germinal centre loss of immunological tolerance appears present in some patients with NMOSD. This study has implications for understanding mechanisms of disease perpetuation and for rational choice of immunotherapies in NMOSD. Furthermore, the in vitro model presents an opportunity to apply condition-specific approaches to patients with NMOSD and may be a paradigm to study other antibody-mediated diseases.awy010media15732448284001. PMID- 29447338 TI - Exposure-Lag-Response in Longitudinal Studies: Application of Distributed-Lag Nonlinear Models in an Occupational Cohort. AB - Prolonged exposures can have complex relationships with health outcomes, as timing, duration, and intensity of exposure are all potentially relevant. Summary measures such as cumulative exposure or average intensity of exposure may not fully capture these relationships. We applied penalized and unpenalized distributed-lag nonlinear models (DLNMs) with flexible exposure-response and lag response functions in order to examine the association between crystalline silica exposure and mortality from lung cancer and nonmalignant respiratory disease in a cohort study of 2,342 California diatomaceous earth workers followed during 1942 2011. We also assessed associations using simple measures of cumulative exposure assuming linear exposure-response and constant lag-response. Measures of association from DLNMs were generally higher than those from simpler models. Rate ratios from penalized DLNMs corresponding to average daily exposures of 0.4 mg/m3 during lag years 31-50 prior to the age of observed cases were 1.47 (95% confidence interval (CI): 0.92, 2.35) for lung cancer mortality and 1.80 (95% CI: 1.14, 2.85) for nonmalignant respiratory disease mortality. Rate ratios from the simpler models for the same exposure scenario were 1.15 (95% CI: 0.89, 1.48) and 1.23 (95% CI: 1.03, 1.46), respectively. Longitudinal cohort studies of prolonged exposures and chronic health outcomes should explore methods allowing for flexibility and nonlinearities in the exposure-lag-response. PMID- 29447340 TI - Dysfunction of DNA damage-inducible transcript 4 in the decidua is relevant to the pathogenesis of preeclampsia. AB - Preeclampsia (PE) is a pregnancy-related disorder that occurs after 20 weeks of gestation and affects 3-5% of all human pregnancies worldwide. However, the pathogenesis of PE still remains poorly understood. A deficiency in decidualization is considered a contributing factor to the development of PE. The DNA damage inducible transcript 4 (DDIT4) gene encodes a protein whose main function is inhibiting mammalian target of rapamycin (mTOR) under stress, and several studies have demonstrated that its expression promotes tumor cell apoptosis. Our previous RNA-Seq results showed that DDIT4 is significantly decreased in the decidua of PE women. Here, we aimed to define the role of DDIT4 in human decidualization and its relationship with PE. The results indicated that DDIT4 was markedly decreased in the decidua of severe PE compared with those from uncomplicated pregnancies. The expression of DDIT4 in human endometrial stromal cell (hESC) line and primary hESCs was up-regulated during decidualization. Knockdown DDIT4 in hESCs and primary hESCs caused a significant reduction in the transcription of decidualization markers, insulin-like growth factor binding protein 1 (IGFBP1) and prolactin (PRL). In addition, silencing DDIT4 caused up regulated p-mTOR and p-p70s6k and reduced apoptosis, whereas rapamycin, an inhibitor of mTOR, reversed the result of apoptosis. Moreover, the expression of cleaved-caspase 3 in severe PE was significantly lower than that of uncomplicated pregnancies, which was unfavorable for trophoblast invasion. Our data suggest that DDIT4 is critical for normal decidualization and the apoptosis of decidual cells. DDIT4 deficiency is likely involved in the development of PE. PMID- 29447339 TI - Integrated microRNA and mRNA network analysis of the human myometrial transcriptome in the transition from quiescence to labor. AB - We conducted integrated transcriptomics network analyses of miRNA and mRNA interactions in human myometrium to identify novel molecular candidates potentially involved in human parturition. Myometrial biopsies were collected from women undergoing primary Cesarean deliveries in well-characterized clinical scenarios: (1) spontaneous term labor (TL, n = 5); (2) term nonlabor (TNL, n = 5); (3) spontaneous preterm birth (PTB) with histologic chorioamnionitis (PTB HCA, n = 5); and (4) indicated PTB nonlabor (PTB-NL, n = 5). RNAs were profiled using RNA sequencing, and miRNA-target interaction networks were mined for key discriminatory subnetworks. Forty miRNAs differed between TL and TNL myometrium, while seven miRNAs differed between PTB-HCA vs. PTB-NL specimens; six of these were cross-validated using quantitative PCR. Based on the combined sequencing data, unsupervised clustering revealed two nonoverlapping cohorts that differed primarily by absence or presence of uterine quiescence, rather than gestational age or original clinical cohort. The intersection of differentially expressed miRNAs and their targets predicted 22 subnetworks with enriched representation of miR-146b-5p, miR-223-3p, and miR-150-5p among miRNAs, and of myocyte enhancer factor-2C (MEF2C) among mRNAs. Of four known MEF2 transcription factors, decreased MEF2A and MEF2C expression in women with uterine nonquiescence was observed in the sequencing data, and validated in a second cohort by quantitative PCR. Immunohistochemistry localized MEF2A and MEF2C to myometrial smooth muscle cells and confirmed decreased abundance with labor. Collectively, these results suggest altered MEF2 expression may represent a previously unrecognized process through which miRNAs contribute to the phenotypic switch from quiescence to labor in human myometrium.

PMID- 29447342 TI - Diagnosing coronary artery disease after a positive coronary computed tomography angiography: the Dan-NICAD open label, parallel, head to head, randomized controlled diagnostic accuracy trial of cardiovascular magnetic resonance and myocardial perfusion scintigraphy. AB - Aims: Perfusion scans after coronary computed tomography angiography (CCTA) in patients with suspected coronary artery disease (CAD) may reduce unnecessary invasive coronary angiographies (ICAs). However, the diagnostic accuracy of perfusion scans after primary CCTA is unknown. The aim of this study was to determine the diagnostic accuracy of cardiac magnetic resonance (CMR) and myocardial perfusion scintigraphy (MPS) against ICA with fractional flow reserve (FFR) in patients suspected of CAD by CCTA. Methods and results: Included were consecutive patients (1675) referred to CCTA with symptoms of CAD and low/intermediate risk profile. Patients with suspected CAD based on CCTA were randomized 1:1 to CMR or MPS followed by ICA with FFR. Obstructive CAD was defined as FFR <= 0.80 or > 90% diameter stenosis by visual assessment. After initial CCTA, 392 patients (23%) were randomized; 197 to CMR and 195 to MPS. Perfusion scans and ICA were completed in 292 patients (CMR 148, MPS 144). Based on the ICA, 117/292 (40%) patients were classified with CAD. Sensitivity, specificity, negative predictive value (NPV), and positive predictive value (PPV) for CMR were 41%, 95% CI [28-54], 84% [75-91], 62% [45-78], and 68% [58-76], respectively. For the MPS group 36% [24-50], 94% [87-98], 81% [61-93], and 68% [59-76], respectively. Conclusion: Patients with low/intermediate CAD risk and a positive CCTA scan represent a challenge to perfusion techniques indicated by the low sensitivity of both CMR and MPS with FFR as a reference. The mechanisms underlying this discrepancy need further investigation. PMID- 29447343 TI - Reply to Rescigno et al. PMID- 29447344 TI - The balance between short-term and long-term outcomes of bilateral internal thoracic artery skeletonization in coronary artery bypass surgery: a propensity matched cohort study. AB - OBJECTIVES: There is growing interest in the use of bilateral internal thoracic arteries (BITAs) for myocardial revascularization. This study sought to compare the balance between early benefits and long-term outcomes of skeletonized or non skeletonized conduits and to determine whether differences in outcomes are affected by other patient risk factors. METHODS: BITAs were used in 1504 cases with either SK or NSK conduits. Propensity matching was completed using 22 covariates identifying 441 pairs of patients. The primary outcomes are the sternal wound infection in the short term and the composite outcome of all-cause mortality, myocardial infarction, revascularization and congestive heart failure. Outcomes were assessed using paired analysis techniques and Cox proportional hazards regression models stratified using the matched pairs. RESULTS: Incidences of in-hospital mortality and perioperative myocardial infarction were similar in both groups. There were fewer sternal wound infections in the SK group (5.4 vs 9.1%, P = 0.033). Homogeneity testing of the relative risk estimates confirmed that there was a protective effect of skeletonization in men that was not demonstrated in women (P = 0.020). SK had a protective effect in diabetics not seen in non-diabetics (P = 0.048). The composite outcome of all-cause mortality, myocardial infarction, revascularization and congestive heart failure at a median of 5.6 years was comparable in both groups (hazard ratio 0.81, 95% confidence interval 0.57-1.15). CONCLUSION: Skeletonization results in better perioperative outcomes and comparable cardiac outcomes in patients undergoing BITA with the greatest benefit in men and patients with chronic obstructive pulmonary disease.

AB - We propose a novel approach for the flexible modeling of complex exposure-lag response associations in time-to-event data, where multiple past exposures within a defined time window are cumulatively associated with the hazard. Our method allows for the estimation of a wide variety of effects, including potentially smooth and smoothly time-varying effects as well as cumulative effects with leads and lags, taking advantage of the inference methods that have recently been developed for generalized additive mixed models. We apply our method to data from a large observational study of intensive care patients in order to analyze the association of both the timing and the amount of artificial nutrition with the short term survival of critically ill patients. We evaluate the properties of the proposed method by performing extensive simulation studies and provide a systematic comparison with related approaches.

AB - Background: The prevalence of both obesity and type 2 diabetes has been on the rise in China. This randomized controlled trial was conducted to test the feasibility and effectiveness of an evidence-based diabetes prevention program in Yuci, Shanxi Province, China from 2012 to 2014. Methods: Women with pre-diabetes, ages 25-65 y, were assigned randomly to a comparison (n=75) or 6-mo lifestyle intervention condition (n=109). Weight, fasting glucose, hemoglobin A1c and self reported diet and physical activity were measured at baseline, 6 mo and 12 mo. Results: All measures except fasting glucose improved favorably in both comparison and intervention participants at the 6- and 12-mo follow-ups. Participants in the intervention group lost more weight (-0.91 kg, p<0.05) and had a lower body mass index (-0.39 kg/m2, p<0.05) than the comparison group at follow-up. A total of 31.6% (31/98) and 16.2% (11/68) of the participants in the intervention and comparison groups, respectively, achieved the weight loss goal of 5% at follow-up. There was no significant group difference in outcome measures at the 12-mo follow-up. Participants in the intervention group also showed favorable changes in self-reported diet and physical activity measures. Conclusions: A lifestyle intervention to prevent diabetes in at-risk women in community health centers in China is feasible and acceptable but effect sizes were small.

AB - Genetic changes due to dietary intervention in the form of either calorie restriction (CR) or intermittent fasting (IF) are not reported in detail until now. However, it is well established that both CR and IF extend the lifespan and protect against neurodegenerative diseases and stroke. The current research aims were first to describe the transcriptomic changes in brains of IF mice and, second, to determine whether IF induces extensive transcriptomic changes following ischemic stroke to protect the brain from injury. Mice were randomly assigned to ad libitum feeding (AL), 12 (IF12) or 16 (IF16) h daily fasting. Each diet group was then subjected to sham surgery or middle cerebral artery occlusion and consecutive reperfusion. Mid-coronal sections of ipsilateral cerebral tissue were harvested at the end of the 1 h ischemic period or at 3, 12, 24 or 72 h of reperfusion, and genome-wide mRNA expression was quantified by RNA sequencing. The cerebral transcriptome of mice in AL group exhibited robust, sustained up regulation of detrimental genetic pathways under ischemic stroke, but activation of these pathways was suppressed in IF16 group. Interestingly, the cerebral transcriptome of AL mice was largely unchanged during the 1 h of ischemia, whereas mice in IF16 group exhibited extensive up-regulation of genetic pathways involved in neuroplasticity and down-regulation of protein synthesis. Our data provide a genetic molecular framework for understanding how IF protects brain cells against damage caused by ischemic stroke, and reveal cellular signaling and bioenergetic pathways to target in the development of clinical interventions. PMID- 29447350 TI - Soil protists: a fertile frontier in soil biology research. AB - Protists include all eukaryotes except plants, fungi and animals. They are an essential, yet often forgotten, component of the soil microbiome. Method developments have now furthered our understanding of the real taxonomic and functional diversity of soil protists. They occupy key roles in microbial foodwebs as consumers of bacteria, fungi and other small eukaryotes. As parasites of plants, animals and even of larger protists, they regulate populations and shape communities. Pathogenic forms play a major role in public health issues as human parasites, or act as agricultural pests. Predatory soil protists release nutrients enhancing plant growth. Soil protists are of key importance for our understanding of eukaryotic evolution and microbial biogeography. Soil protists are also useful in applied research as bioindicators of soil quality, as models in ecotoxicology and as potential biofertilizers and biocontrol agents. In this review, we provide an overview of the enormous morphological, taxonomical and functional diversity of soil protists, and discuss current challenges and opportunities in soil protistology. Research in soil biology would clearly benefit from incorporating more protistology alongside the study of bacteria, fungi and animals. PMID- 29447351 TI - Research versus practice in quality improvement? Understanding how we can bridge the gap. AB - The gap between implementers and researchers of quality improvement (QI) has hampered the degree and speed of change needed to reduce avoidable suffering and harm in health care. Underlying causes of this gap include differences in goals and incentives, preferred methodologies, level and types of evidence prioritized and targeted audiences. The Salzburg Global Seminar on 'Better Health Care: How do we learn about improvement?' brought together researchers, policy makers, funders, implementers, evaluators from low-, middle- and high-income countries to explore how to increase the impact of QI. In this paper, we describe some of the reasons for this gap and offer suggestions to better bridge the chasm between researchers and implementers. Effectively bridging this gap can increase the generalizability of QI interventions, accelerate the spread of effective approaches while also strengthening the local work of implementers. Increasing the effectiveness of research and work in the field will support the knowledge translation needed to achieve quality Universal Health Coverage and the Sustainable Development Goals.

Intervention(s): To apply lean techniques such as value stream mapping, workplace organization, reduction of wastes and standardization by the frontline staff. Main Outcome Measure(s): Two periods were compared: (i) pre-lean: April-September, 2015; and (ii) post-lean: April-September, 2016. Variables included: median process time (time from beginning of nurse preparation to the end of nurse finalization after doctor disposition) of both discharged and transferred to observation patients; median length of stay; median waiting time; left without being seen, 72-h revisit and mortality rates, and daily number of visits. There was no additional staff or bed after lean implementation. Results: Despite an increment in the daily number of visits (+8.3%, P < 0.001), significant reductions in process time of discharged (182 vs 160 min, P < 0.001) and transferred to observation (186 vs 176 min, P < 0.001) patients, in length of stay (389 vs 329 min, P < 0.001), and in waiting time (71 vs 48 min, P < 0.001) were achieved after lean implementation. No significant differences were registered in left without being seen rate (5.23% vs 4.95%), 72-h revisit rate (3.41% vs 3.93%), and mortality rate (0.23% vs 0.15%). Conclusion: Lean thinking is a methodology that can improve triage acuity level-3 patient flow in the ED, resulting in better throughput along with reduced waiting time.

AB - Globalization is having an ever growing impact on the field of vaccine production and distribution in the world and domestically. In this article we examine the impact of taking a strategic approach to vaccination programmes by all the relevant actors: WHO, UNICEF, national immunization programmes, and vaccine manufacturers and distributors. The review of the relevant literature indicates that there are commonalities to the worldwide vaccination programmes. A comparative analysis of various vaccination strategies recommended by WHO and the immunization calendars of certain European countriesis made as well as an analysis of the Serbian vaccination programme. New and more expensive vaccines will continue to appear on the market in increasingly short periods of time. PMID- 29447354 TI - CREB3 regulatory factor -mTOR-autophagy regulates goat endometrial function during early pregnancy. AB - In domestic ruminants, a receptive endometrium is crucial for successful pregnancy. Although many essential molecular modulators and pathways have been identified during early pregnancy, the precise mechanisms regulating goat endometrial function remains largely unknown. Here, we describe a novel regulator during early pregnancy, whereby hormones increased CREB3 regulatory factor (CREBRF) expression and act as a potential activator of autophagy in endometrial epithelial cells (EECs) via the mTOR pathway. Our results showed that knockdown of CREBRF via shCREBRF hampered EECs proliferation by S-phase cell cycle arrest and significantly inhibited endometrial function. We also reported that CREBRF mTOR-autophagy pathway plays a vital role in regulating endometrial function, with a blockade of the mTOR by rapamycin demonstrating the regulatory function on prostaglandin (PGs) secretion and cell attachment in EECs. Moreover, chloroquine pretreatment also proved the above conclusion. Collectively, our findings provide new insight into the molecular mechanisms of goat endometrial function and indicate that the CREBRF-mTOR-autophagy pathway plays a central role in PGs secretion and cell attachment.

PMID- 29447356 TI - Barriers to the availability and accessibility of controlled medicines for chronic pain in Africa. AB - Africans endure a high burden of pain and suffering from HIV/AIDS and cancer, yet receive a meager amount of the world's pain medication. This tragedy occurs needlessly, given that inexpensive, effective and easily administered interventions are available. WHO has a 'three-step analgesic ladder' framework for managing cancer pain. This widely adopted clinical practice guideline is an integral part of palliative care programs and has also been applied to non-cancer pain. However, untreated pain is a major public health problem due to the discordance between scientific evidence and public policy. Historically, the International Narcotics Board has taken an unbalanced prohibitionist approach to international drug control that has emphasized suppressing controlled substances over making them available for medical and scientific purposes. The procurement process for controlled pain medications in most African countries is a morass of restrictions that make it exceedingly difficult for patients to obtain these drugs. Often, these restrictions arise in part from a misunderstanding of addiction and dependence on opiates. The result has been widespread 'opiophobia' among African policy makers and physicians. A host of factors have misaligned the analgesic pharmaceutical supply chain. Taken together, access to medically necessary controlled substance in sub-Saharan Africa is suboptimal. PMID- 29447357 TI - Analysis of cluster-randomized test-negative designs: cluster-level methods. AB - Intervention trials of vector control methods often require community level randomization with appropriate inferential methods. For many interventions, the possibility of confounding due to the effects of health-care seeking behavior on disease ascertainment remains a concern. The test-negative design, a variant of the case-control method, was introduced to mitigate this issue in the assessment of the efficacy of influenza vaccination (measured at an individual level) on influenza infection. Here, we introduce a cluster-randomized test-negative design that includes randomization of the intervention at a group level. We propose several methods for estimation and inference regarding the relative risk (RR). The inferential methods considered are based on the randomization distribution induced by permuting intervention assignment across two sets of randomly selected clusters. The motivating example is a current study of the efficacy of randomized releases of Wolbachia-infected Aedes aegypti mosquitoes to reduce the incidence of dengue in Yogyakarta City, Indonesia. Estimation and inference techniques are assessed through a simulation study. PMID- 29447358 TI - Factors associated with maternal utilization of health facilities for delivery in Ethiopia. AB - Background: As a signatory of the Millennium Development Goals, Ethiopia has made significant achievements towards meeting the maternal mortality related goals since 1990. Despite that, the country is still experiencing unacceptably high maternal mortality rates, and challenges to improving the coverage and utilisation of health facility delivery services which represent a key strategy to combat maternal mortality. Currently, there is limited evidence on the factors associated with health facility delivery in Ethiopia. Therefore, the objective of this study was to identify the correlates of facility delivery among urban and rural women in Ethiopia. Methods: This was a cross-sectional study based on data from the 2011 Ethiopian Demographic and Health Survey. Participants were 7540 women aged between 15 and 49 years with a history of at least one birth. The outcome variable was place of delivery. Data were analyzed using bivariate and multivariable regression techniques. Results: The overall prevalence of health facility delivery was 17.1% (1447/7540). In the multivariable regression analysis, education, wealth status, frequency of antenatal care visits and mother's age at first birth were found to be significantly associated with women's choice of place of delivery. Among urban women, those who had primary and secondary/higher level education had increased odds of delivering at a health facility compared with those without formal education. Those who were from the richest households had higher odds of delivering at a health facility compared with those in the lowest class. In urban and rural areas, compared with those who had no ANC visits, those who had at least four visits also had increased odds of delivering at a health facility. In the urban areas, those who were over 18 years old at their first childbirth had significantly higher odds of choosing to deliver at a health facility. Conclusion: Findings show that the prevalence of healthy facility delivery in Ethiopia is remarkably low. Addressing the sociodemographic and wealth inequities can help promote the utilisation of facility delivery in both urban and rural areas. Policy-makers should consider improving access to education as a strategy to meet maternal health related goals and treat education as a multipronged strategy. Providing free healthcare access could be one strategy to achieve the universal coverage of essential maternal healthcare services. PMID- 29447359 TI - ACTN3 genotype and physical function and frailty in an elderly Chinese population: the Rugao Longevity and Ageing Study. AB - Objective: To examine the associations of the actinin alpha 3 gene (ACTN3) R577X polymorphism with physical performance and frailty in an older Chinese population. Methods: Data from 1,463 individuals (57.8% female) aged 70-87 years from the Rugao Longevity and Ageing Study were used. The associations between R577X and timed 5-m walk, grip strength, timed Up and Go test, and frailty index (FI) based on deficits of 23 laboratory tests (FI-Lab) were examined. Analysis of variance and linear regression models were used to evaluate the genetic effects of ACTN3 R577X on physical performance and FI-Lab. Results: The XX and RX genotypes of the ACTN3 R557X polymorphism accounted for 17.1 and 46.9%, respectively. Multivariate regression analysis revealed that in men aged 70-79 years, the ACTN3 577X allele was significantly associated with physical performance (5-m walk time, regression coefficient (beta) = 0.258, P = 0.006; grip strength, beta = -1.062, P = 0.012; Up and Go test time beta = 0.368, P = 0.019). In women aged 70-79 years, a significant association between the ACTN3 577X allele and the FI-Lab score was observed, with a regression coefficient of beta = 0.019 (P = 0.003). These findings suggest an age- and gender-specific X additive model of R577X for 5-m walk time, grip strength, Up and Go Test time, and FI-Lab score. Conclusion: The ACTN3 577X allele is associated with an age- and sex-specific decrease in physical performance and an increase in frailty in an older population. PMID- 29447360 TI - Allocation of Treatment Responsibility in Adolescents With Epilepsy: Associations With Cognitive Skills and Medication Adherence. AB - Objectives: To describe allocation of treatment responsibility (ATR) in adolescents with epilepsy, investigate associations between cognitive skills and ATR, and examine whether ATR for antiepileptic drugs (AEDs) predicted electronically monitored adherence. Method: Sixty adolescents with epilepsy and their caregivers completed the Allocation of Treatment Responsibility Scale and a battery of self-report measures. Medical chart review data and electronically monitored AED adherence were collected for 1 year. Descriptive data assessed ATR for caregivers and adolescents; multivariate hierarchical regressions tested associations between variables. Results: ATR for labs and clinic appointments was greatest for caregivers, while ATR for AEDs was more likely to be shared between caregiver and adolescent. Poorer attention was associated with greater caregiver responsibility for AEDs. Greater caregiver responsibility for AEDs was associated with higher electronically monitored adherence over 12 months. Conclusions: In adolescents with epilepsy, caregivers are responsible for most treatment tasks, although responsibility for taking medication was shared with the adolescent. Greater caregiver responsibility for medication results in better long-term AED adherence. ATR is an important construct that warrants further attention in research and clinical practice, especially in the context of transition and health outcomes in pediatric epilepsy. PMID- 29447361 TI - Laryngeal squamous cell papilloma is highly associated with human papillomavirus. AB - Objective: To delineate the association between characteristics of adult-onset laryngeal squamous cell papilloma and human papillomavirus (HPV) infection. Methods: Clinical records and paraffin-embedded specimens of 77 papilloma patients who had been treated between 1998 and 2014 were collected. Of the 77 cases, 34 were identified in the larynx, 28 in the oral cavity and 15 in the oropharynx. Specimens were investigated by polymerase chain reaction (PCR) to detect HPV 6, 11, 16, 18, 31, 33, 35, 52b and 58, and immunohistochemical (IHC) staining for anti-p16INK4a antibody. Results: In 21 cases (61.8%) with laryngeal squamous cell papilloma, various types of HPV were detected: 14 cases (41.2%) were positive of high-risk HPV, 18 (52.9%) were positive of low-risk HPV and 11 (32.4%) were positive of both high-risk HPV and low-risk HPV. Younger patients (<60 years) showed a higher rate of HPV infection than older patients. Among the 34 cases with laryngeal papilloma, no malignant transformation was observed during the study period. With IHC staining, positive expression of p16 was observed in 20 cases (58.8%). HPV infection and p16-expression were associated with the pathological finding of koilocytosis. Only four cases (14.3%) showed HPV positivity in the oral cavity, and none of the 15 oropharyngeal cases were positive for HPV, and none of the oral cavity and oropharyngeal cases showed koilocytosis. Results of HPV-PCR and p16-IHC staining were significantly correlated each other. Conclusions: HPV infection is frequently associated with laryngeal squamous cell papilloma, and koilocytosis is a characteristic pathological finding. To the best of our knowledge, this is the first report which have described infections with multiple HPV types in laryngeal papilloma. PMID- 29447362 TI - EQ-5D-Y for the assessment of health-related quality of life among Taiwanese youth with mild-to-moderate chronic kidney disease. AB - Objective: To assess if health-related quality of life (HRQOL) of children with chronic kidney disease (CKD) and different comorbid conditions can be identified based on the EQ-5D child-friendly version (EQ-5D-Y). Design: Prospective cross sectional study. Setting: A tertiary care medical center in Taiwan. Study participants: All CKD patients aged 7-18 years treated at the center between May 2014 and December 2016. Main Outcome Measures: HRQOL assessment was done using EQ 5D-Y. Spearman correlation tests were used for construct validity of the traditional Chinese version of EQ-5D-Y. Test-retest reliability was determined through Cohen's kappa values and intraclass correlation coefficients (ICC). Laboratory results and CKD-related morbid conditions were ascertained and assessed their associations with HRQOL score using multivariate linear regression. Results: Of 68 participants, 53 of them completed two HRQOL assessments of HRQOL at least 6-month. Cross-sectional analysis revealed fair to moderate correlations between EQ visual analogue score and patient characteristics. Older children at assessment (P < 0.01), girls (P = 0.03) and presence of mineral bone disorders had a significantly negative impact on HRQOL. Children self-reported EQ-5D-Y dimensions were found to be fairly to highly reliable (kappa = 0.2 to 0.8), except for 'pain/discomfort' and 'anxiety/depression'. Conclusions: The EQ-5D-Y discriminated among children with different level of CKD-related clinical burden, but the psychometric properties may be limited in some HRQOL dimensions. Further research will need to address factors that may threaten validity and reliability data provided by children and adolescents.

Furthermore, the influence of x-ray noise on transmission electron microscopy measurements is discussed and observations on its composition are shared. PMID- 29447364 TI - Salzburg Global Seminar Session 565-'Better Health Care: how do we learn about improvement?' AB - A fundamental question for the field of healthcare improvement is the extent to which the results achieved can be attributed to the changes that were implemented and whether or not these changes are generalizable. Answering these questions is particularly challenging because the healthcare context is complex, and the interventions themselves tend to be complex and multi-dimensional. The Salzburg Global Seminar Session 565-'Better Health Care: How do we learn about improvement?' was convened to address questions of attribution, generalizability and rigor, and to think through how to approach these concerns in the field of quality improvement. The Salzburg Global Seminar Session 565 brought together 61 leaders in improvement from 22 countries, including researchers, evaluators and improvers. The primary conclusion that resulted from the session was the need for evaluation to be embedded as an integral part of the improvement. We have invited participants of the seminar to contribute to writing this supplement, which consists of eight articles reflecting insights and learning from the Salzburg Global Seminar. This editorial serves as an introduction to the supplement. The supplement explains results and insights from Salzburg Global Seminar Session 565. PMID- 29447365 TI - Cohort Profile: The Quebec Birth Cohort on Immunity and Health (QBCIH). PMID- 29447367 TI - Endometrial natural killer (NK) cells reveal a tissue-specific receptor repertoire. AB - STUDY QUESTION: Is the natural killer (NK) cell receptor repertoire of endometrial NK (eNK) cells tissue-specific? SUMMARY ANSWER: The NK cell receptor (NKR) expression profile in pre-pregnancy endometrium appears to have a unique tissue-specific phenotype, different from that found in NK cells in peripheral blood, suggesting that these cells are finely tuned towards the reception of an allogeneic fetus. WHAT IS KNOWN ALREADY: NK cells are important for successful pregnancy. After implantation, NK cells encounter extravillous trophoblast cells and regulate trophoblast invasion. NK cell activity is amongst others regulated by C-type lectin heterodimer (CD94/NKG2) and killer cell immunoglobulin-like (KIR) receptors. KIR expression on decidual NK cells is affected by the presence of maternal HLA-C and biased towards KIR2D expression. However, little is known about NKR expression on eNK cells prior to pregnancy. STUDY DESIGN SIZE, DURATION: In this study, matched peripheral and menstrual blood (a source of endometrial cells) was obtained from 25 healthy females with regular menstrual cycles. Menstrual blood was collected during the first 36 h of menstruation using a menstrual cup, a non-invasive technique to obtain endometrial cells. PARTICIPANTS/MATERIALS, SETTING, METHODS: KIR and NKG2 receptor expression on eNK cells was characterized by 10-color flow cytometry, and compared to matched pbNK cells of the same female. KIR and HLA-C genotypes were determined by PCR-SSOP techniques. Anti-CMV IgG antibodies in plasma were measured by chemiluminescence immunoassay. MAIN RESULTS AND THE ROLE OF CHANCE: KIR expression patterns of eNK cells collected from the same female do not differ over consecutive menstrual cycles. The percentage of NK cells expressing KIR2DL2/L3/S2, KIR2DL3, KIR2DL1, LILRB1 and/or NKG2A was significantly higher in eNK cells compared to pbNK cells, while no significant difference was observed for NKG2C, KIR2DL1/S1, and KIR3DL1. The NKR repertoire of eNK cells was clearly different from pbNK cells, with eNK cells co-expressing more than three NKR simultaneously. In addition, outlier analysis revealed 8 and 15 NKR subpopulation expansions in eNK and pbNK cells, respectively. In contrast to the pbNK cell population, the expansions present in the eNK cell population were independent of CMV status and HLA-C genotype. Moreover, the typical NKG2C imprint induced by CMV infection on pbNK cells was not observed on eNK cells from the same female, suggesting a rapid local turnover of eNK cells and/or a distinct licensing process. LIMITATIONS REASONS FOR CAUTION: Based on our previous work and the parameters studied here, menstrual blood-derived eNK cells closely resemble biopsy-derived eNK cells. However, sampling is not done at the exact same time during the menstrual cycle, and therefore we cannot exclude some, as yet undetected, differences. WIDER IMPLICATIONS OF THE FINDINGS: Our data reveals that NK cells in the pre implantation endometrium appear to have a dedicated tissue-specific phenotype, different from NK cells in peripheral blood. This may indicate that eNK cells are finely tuned to receive an allogeneic fetus. Studying the endometrial NKR repertoire of women with pregnancy related problems could provide clues to understand the pathogenesis of pregnancy complications.

AB - An 11-month-old girl with an unbalanced atrioventricular septal defect, coarctation of the aorta and an interrupted inferior vena cava with hemiazygos continuation post-surgical status of coarctation repair and pulmonary artery banding underwent a Kawashima operation. Severe hypoxia occurred immediately after she was weaned from cardiopulmonary bypass, which was successfully resolved by the ligation of the hemiazygos vein. Postoperative enhanced computed tomography detected significant venovenous malformation from the hemiazygos vein to the left renal vein. PMID- 29447366 TI - Parent-of-Origin-Dependent Gene Expression in Male and Female Schistosome Parasites. AB - Schistosomes are the causative agents of schistosomiasis, a neglected tropical disease affecting over 230 million people worldwide. Additionally to their major impact on human health, they are also models of choice in evolutionary biology. These parasitic flatworms are unique among the common hermaphroditic trematodes as they have separate sexes. This so-called "evolutionary scandal" displays a female heterogametic genetic sex-determination system (ZZ males and ZW females), as well as a pronounced adult sexual dimorphism. These phenotypic differences are determined by a shared set of genes in both sexes, potentially leading to intralocus sexual conflicts. To resolve these conflicts in sexually selected traits, molecular mechanisms such as sex-biased gene expression could occur, but parent-of-origin gene expression also provides an alternative. In this work we investigated the latter mechanism, that is, genes expressed preferentially from either the maternal or the paternal allele, in Schistosoma mansoni species. To this end, transcriptomes from male and female hybrid adults obtained by strain crosses were sequenced. Strain-specific single nucleotide polymorphism (SNP) markers allowed us to discriminate the parental origin, while reciprocal crosses helped to differentiate parental expression from strain-specific expression. We identified genes containing SNPs expressed in a parent-of-origin manner consistent with paternal and maternal imprints. Although the majority of the SNPs was identified in mitochondrial and Z-specific loci, the remaining SNPs found in male and female transcriptomes were situated in genes that have the potential to explain sexual differences in schistosome parasites. Furthermore, we identified and validated four new Z-specific scaffolds. PMID- 29447369 TI - Mandatory Change From Surgical Skull Caps to Bouffant Caps Among Operating Room Personnel Does Not Reduce Surgical Site Infections in Class I Surgical Cases: A Single-Center Experience With More Than 15 000 Patients. AB - BACKGROUND: Surgical site infections (SSIs) are noteworthy and costly complications. New recommendations from a national organization have urged the elimination of traditional surgeon's caps (surgical skull caps) and mandated the use of bouffant caps to prevent SSIs. OBJECTIVE: To report SSI rates for >15 000 class I (clean) surgical procedures 13 mo before and 13 mo after surgical skull caps were banned at a single site with 25 operating rooms. METHODS: SSI data were acquired from hospital infection control monthly summary reports from January 2014 to March 2016. Based on a change in hospital policy mandating obligatory use of bouffant caps since February 2015, data were categorized into nonbouffant and bouffant groups. Monthly and cumulative infection rates for 13 mo before (7513 patients) and 13 mo after (8446 patients) the policy implementation were collected and analyzed for the groups, respectively. RESULTS: An overall increase of 0.07% (0.77%-0.84%) in the cumulative rate of SSI in all class I operating room cases and of 0.03% (0.79%-0.82%) in the cumulative rate of SSI in all spinal procedures was noted. However, neither increase reached statistical significance (P > .05). The cumulative rate of SSI in neurosurgery craniotomy/craniectomy cases decreased from 0.95% to 0.75%; this was also not statistically significant (P = 1.00). CONCLUSION: National efforts at improving healthcare performance are laudable but need to be evidence based. Guidelines, especially when applied in a mandatory fashion, should be assessed for effectiveness. In this large, single center series of patients undergoing class I surgical procedures, elimination of the traditional surgeon's cap did not reduce infection rates. PMID- 29447370 TI - Management of gout by UK rheumatologists: a British Society for Rheumatology national audit. AB - Objectives: To assess the concordance of gout management by UK rheumatologists with evidence-based best-practice recommendations. Methods: Data were collected on patients newly referred to UK rheumatology out-patient departments over an 8 week period. Baseline data included demographics, method of diagnosis, clinical features, comorbidities, urate-lowering therapy (ULT), prophylaxis and blood tests. Twelve months later, the most recent serum uric acid level was collected. Management was compared with audit standards derived from the 2006 EULAR recommendations, 2007 British Society for Rheumatology/British Health Professionals in Rheumatology guideline and the National Institute for Health and Care Excellence febuxostat technology appraisal. Results: Data were collected for 434 patients from 91 rheumatology departments (mean age 59.8 years, 82% male). Diagnosis was crystal-proven in 13%. Of 106 taking a diuretic, this was reduced/stopped in 29%. ULT was continued/initiated in 76% of those with one or more indication for ULT. One hundred and fifty-eight patients started allopurinol: the starting dose was most commonly 100 mg daily (82%); in those with estimated glomerular filtration rate <60 ml/min the highest starting dose was 100 mg daily. Of 199 who started ULT, prophylaxis was co-prescribed for 94%. Fifty patients started a uricosuric or febuxostat: 84% had taken allopurinol previously. Of 44 commenced on febuxostat, 18% had a history of heart disease. By 12 months, serum uric acid levels ?360 and <300 MUmol/l were achieved by 45 and 25%, respectively. Conclusion: Gout management by UK rheumatologists concords well with guidelines for most audit standards. However, fewer than half of patients achieved a target serum uric level over 12 months. Rheumatologists should help ensure that ULT is optimized to achieve target serum uric acid levels to benefit patients. PMID- 29447371 TI - Getting shops to voluntarily stop selling cheap, strong beers and ciders: a time series analysis evaluating impacts on alcohol availability and purchasing. AB - Background: 'Reducing the Strength' (RtS) is a public health initiative encouraging retailers to voluntarily stop selling cheap, strong beers/ciders (>=6.5% alcohol by volume). This study evaluates the impact of RtS initiatives on alcohol availability and purchasing in three English counties with a combined population of 3.62 million people. Methods: We used a multiple baseline time series design to examine retail data over 29 months from a supermarket chain that experienced a two-wave, area-based role out of RtS: initially 54 stores (W1), then another 77 stores (W2). We measured impacts on units of alcohol sold (primary outcome: beers/ciders; secondary outcome: all alcoholic products), economic impacts on alcohol sales and substitution effects. Results: We observed a non-significant W1 increase (+3.7%, 95% CI: -11.2, 21.0) and W2 decrease ( 6.8%, 95% CI: -20.5, 9.4) in the primary outcome. We observed a significant W2 decrease in units sold across all alcohol products (-10.5%, 95% CI: -19.2, -0.9). The direction of effect between waves was inconsistent for all outcomes, including alcohol sales, with no evidence of substitution effects. Conclusions: In the UK, voluntary RtS initiatives appear to have little or no impact on reducing alcohol availability and purchase from the broader population of supermarket customers. PMID- 29447372 TI - Small Fiber Polyneuropathy Is Prevalent in Patients Experiencing Complex Chronic Pelvic Pain. AB - Objective: To demonstrate the prevalence of small fiber polyneuropathy (SFPN) in patients with refractory chronic pelvic pain (CPP). Design: Retrospective study of prospective database. Subjects: Participants were complex CPP patients recruited from subspecity referral clinics defined as those who were refractory to initial treatment and/or exhibited comorbid pain syndromes at initial presentation. Methods: Comprehensive treatment history for CPP was obtained, and participants referred as above; 3-mm punch biopsies were obtained of the lower extremity and sent to diagnostic reference labs to evaluate for SFPN. The reported lab sensitivity and specificity for SFPN are 78-92% and 65-90%, respectively. Results: Twenty-five of 39 patients (64%) were positive for SFPN. Comorbid conditions noted in our population included gastroesophageal reflux disease (46%), migraine (38%), irritable bowel syndrome (33%), lower back pain (33%), fibromyalgia (38%), endometriosis (15%), interstitial cystitis (18%), vulvodynia (5%), and other chronic pain syndromes (36%). Conclusions: The prevalence of SFPN in our specialty referral patients with complex CPP is remarkably high vs published general population prevalence data (53/100,000). Identification of SFPN in this complex population shifts the focus from undefined syndromes to symptom complexes with linked potentially treatable mechanisms (e.g., SFPN, central sensitization). Most CPP patients with SFPN are undiagnosed. Considering the diagnosis may expand treatment options beyond conventional or so called adjuvant analgesics. Treatment may expand to therapies such as IV lidocaine, IVIG, or other immunomodulatory options. In addition, the value to the patient of receiving a diagnosis for a multisystem or refractory pain syndrome, often attributed to negative psychologic factors, cannot be underestimated. Identifying SFPN should be contemplated in CPP patients who present with multisystem pain or who have not responded to initial evaluation and management. PMID- 29447374 TI - Spectrum of Pediatric Tuberculosis in a Tertiary Care Setting in South India. AB - Background: Pediatric tuberculosis (TB) is often underdiagnosed with poor estimate of its true burden. Availability of Xpert MTB/RIF assay enhances diagnostic capacity of pediatric TB. Methods: A 3-year retrospective review of hospital records was done for all children diagnosed with confirmed and unconfirmed TB. Comparison was made between intrathoracic, single-site extrathoracic and disseminated TB. Results: In total, 274 children had TB with 130 (47.4%) having confirmed TB. Pulmonary (23.4%), lymph node (23%) and central nervous system (12.8%) TB were the three commonest forms. HIV TB coinfection was 2.9%. Mycobacterial culture was positive in 90 (32.8%) and XPert MTB/RIF in 85 patients (31%). Mycobacterial confirmation was obtained in 45 (56.3%) intrathoracic TB, 69 (45.4%) extrathoracic TB and 16 (38.1%) disseminated TB. Correlation between positive Xpert and mycobacterial culture was poor (kappa 0.38). Rifampicin resistance was present in 25 (19.2%) of the 130 microbiologically confirmed TB. Conclusion: Extrathoracic TB is common in children. Mycobacterial confirmation in pediatric TB is improved with use of Xpert. PMID- 29447373 TI - Coupling the core of the anticancer drug etoposide to an oligonucleotide induces topoisomerase II-mediated cleavage at specific DNA sequences. AB - Etoposide and other topoisomerase II-targeted drugs are important anticancer therapeutics. Unfortunately, the safe usage of these agents is limited by their indiscriminate induction of topoisomerase II-mediated DNA cleavage throughout the genome and by a lack of specificity toward cancer cells. Therefore, as a first step toward constraining the distribution of etoposide-induced DNA cleavage sites and developing sequence-specific topoisomerase II-targeted anticancer agents, we covalently coupled the core of etoposide to oligonucleotides centered on a topoisomerase II cleavage site in the PML gene. The initial sequence used for this 'oligonucleotide-linked topoisomerase inhibitor' (OTI) was identified as part of the translocation breakpoint of a patient with acute promyelocytic leukemia (APL). Subsequent OTI sequences were derived from the observed APL breakpoint between PML and RARA. Results indicate that OTIs can be used to direct the sites of etoposide-induced DNA cleavage mediated by topoisomerase IIalpha and topoisomerase IIbeta. OTIs increased levels of enzyme-mediated cleavage by inhibiting DNA ligation, and cleavage complexes induced by OTIs were as stable as those induced by free etoposide. Finally, OTIs directed against the PML-RARA breakpoint displayed cleavage specificity for oligonucleotides with the translocation sequence over those with sequences matching either parental gene. These studies demonstrate the feasibility of using oligonucleotides to direct topoisomerase II-mediated DNA cleavage to specific sites in the genome. PMID- 29447375 TI - Coupling individual kernel-filling processes with source-sink interactions into GREENLAB-Maize. AB - Background and Aims: Failure to account for the variation of kernel growth in a cereal crop simulation model may cause serious deviations in the estimates of crop yield. The goal of this research was to revise the GREENLAB-Maize model to incorporate source- and sink-limited allocation approaches to simulate the dry matter accumulation of individual kernels of an ear (GREENLAB-Maize-Kernel). Methods: The model used potential individual kernel growth rates to characterize the individual potential sink demand. The remobilization of non-structural carbohydrates from reserve organs to kernels was also incorporated. Two years of field experiments were conducted to determine the model parameter values and to evaluate the model using two maize hybrids with different plant densities and pollination treatments. Detailed observations were made on the dimensions and dry weights of individual kernels and other above-ground plant organs throughout the seasons. Key Results: Three basic traits characterizing an individual kernel were compared on simulated and measured individual kernels: (1) final kernel size; (2) kernel growth rate; and (3) duration of kernel filling. Simulations of individual kernel growth closely corresponded to experimental data. The model was able to reproduce the observed dry weight of plant organs well. Then, the source-sink dynamics and the remobilization of carbohydrates for kernel growth were quantified to show that remobilization processes accompanied source-sink dynamics during the kernel-filling process. Conclusions: We conclude that the model may be used to explore options for optimizing plant kernel yield by matching maize management to the environment, taking into account responses at the level of individual kernels. PMID- 29447376 TI - The relationship between depression and biologic treatment response in rheumatoid arthritis: An analysis of the British Society for Rheumatology Biologics Register. AB - Objective: To investigate the relationship between depressive symptoms and treatment response and disease activity in RA over a 1-year follow-up. Methods: Data from the British Society for Rheumatology Biologics Register were used, representing 18 421 RA patients receiving biologic treatment. Depressive symptoms were identified through one of three assessments: reporting a history of depression, the Medical Outcomes Survey 36-item Short Form or the EuroQol five dimension scale. Logistic regression analyses examined the relationship between baseline depressive symptoms and odds of good treatment response by 1 year. Multilevel models addressed the association between baseline depressive symptoms and disease activity outcomes over 1-year follow-up, adjusting for age, gender, disease duration, comorbidities and baseline disease activity and physical disability. Results: Depression symptoms at biologic treatment initiation were associated with 20-40% reduced odds of achieving a good treatment response at 1 year. Depressive symptoms at baseline also associated with reduced improvement in disease activity over the course of follow-up. Patients with a history of depression or reporting symptoms of depression according to the EuroQol five dimension scale showed reduced improvement in tender and swollen joints, patient global assessment and ESR over 1-year follow-up. Patients with depression symptoms according to the 36-item Short Form showed reduced improvement in tender and swollen joints, but not ESR or patient global assessment. Conclusion: Experiencing symptoms of depression at the start of biologics treatment may reduce the odds of achieving a good treatment response, and reduce improvement in disease activity over time. Depression should be managed as part of routine clinical care to optimize treatment outcomes. PMID- 29447378 TI - Trace metal metabolism in plants. AB - Many trace metals are essential micronutrients, but also potent toxins. Due to natural and anthropogenic causes, vastly different trace metal concentrations occur in various habitats, ranging from deficient to toxic levels. Therefore, one focus of plant research is on the response to trace metals in terms of uptake, transport, sequestration, speciation, physiological use, deficiency, toxicity, and detoxification. In this review, we cover most of these aspects for the essential micronutrients copper, iron, manganese, molybdenum, nickel, and zinc to provide a broader overview than found in other recent reviews, to cross-link aspects of knowledge in this very active research field that are often seen in a separated way. For example, individual processes of metal usage, deficiency, or toxicity often were not mechanistically interconnected. Therefore, this review also aims to stimulate the communication of researchers following different approaches, such as gene expression analysis, biochemistry, or biophysics of metalloproteins. Furthermore, we highlight recent insights, emphasizing data obtained under physiologically and environmentally relevant conditions. PMID- 29447377 TI - Behavioral and neural indices of affective coloring for neutral social stimuli. AB - Emotional processing often continues beyond the presentation of emotionally evocative stimuli, which can result in affective biasing or coloring of subsequently encountered events. Here, we describe neural correlates of affective coloring and examine how individual differences in affective style impact the magnitude of affective coloring. We conducted functional magnetic resonance imaging in 117 adults who passively viewed negative, neutral and positive pictures presented 2 s prior to neutral faces. Brain responses to neutral faces were modulated by the valence of preceding pictures, with greater activation for faces following negative (vs positive) pictures in the amygdala, dorsomedial and lateral prefrontal cortex, ventral visual cortices, posterior superior temporal sulcus, and angular gyrus. Three days after the magnetic resonance imaging scan, participants rated their memory and liking of previously encountered neutral faces. Individuals higher in trait positive affect and emotional reappraisal rated faces as more likable when preceded by emotionally arousing (negative or positive) pictures. In addition, greater amygdala responses to neutral faces preceded by positively valenced pictures were associated with greater memory for these faces 3 days later. Collectively, these results reveal individual differences in how emotions spill over onto the processing of unrelated social stimuli, resulting in persistent and affectively biased evaluations of such stimuli. PMID- 29447379 TI - Acute exercise is not cardioprotective and may induce apoptotic signalling in heart surgery: a randomized controlled trial. AB - OBJECTIVES: During open-heart surgery, the myocardium experiences ischaemia reperfusion injury. A single bout of moderate, 30-min exercise induces preconditioning and protects the heart from ischaemia-reperfusion injury in rats, but this has never been investigated in humans. We aimed to investigate whether 1 bout of moderate exercise 24 h prior to surgery protects against mitochondrial and cardiac damage. METHODS: Patients scheduled for elective coronary artery bypass were eligible for this pilot study. Twenty were included and randomized to the treadmill exercise group (the EX group, n = 10) 24 h preoperatively or to standard presurgical procedures (control n = 10). Right atrial (RA) and left ventricular (LV) biopsies were collected immediately before and as long as possible after aortic cross-clamping to assess the primary outcome of mitochondrial respiration by respirometry, in addition to reactive oxygen species production by fluorometry and apoptotic transcripts. Cardiac troponin T and creatine kinase myocardial brain were measured in plasma at arrival, before surgery and 6 and 24 h postoperatively. RESULTS: Mitochondrial respiration was lower in the EX group after surgery in the LV (Complex I -22%, P < 0.05 and maximal -23%, P < 0.05) and the right atrium (Complex I -25%, P < 0.05). Transcript level of the apoptosis-related marker caspase 3 was increased 1.5-fold in the LV prior to surgery in the EX group when compared with the control group, P < 0.05. Cardiac troponin T was 45% higher in the EX group than in the control group 6 h postoperatively (P = 0.03), although not significant when corrected for aortic cross-clamping time. CONCLUSIONS: Results indicate that exercise did not precondition the heart against surgery-related damage. Exercise may render the myocardium and mitochondria more vulnerable to perioperative damage.

PMID- 29447380 TI - Sirtuins in gamete biology and reproductive physiology: emerging roles and therapeutic potential in female and male infertility. AB - BACKGROUND: Sirtuins (SIRT1-7) are a family of NAD+-dependent deacetylases that catalyze post-translational modifications of proteins. Together, they respond to metabolic challenges, inflammatory signals or hypoxic/oxidative stress, and are associated with aging and longevity. The role of Sirtuins in the regulation of fertility emerged in 2003 when a defective reproductive phenotype was observed in SIRT1-null mice. Although studies on Sirtuins in reproductive biology have been increasing in the last years, a recent comprehensive update on this issue is still lacking. OBJECTIVE AND RATIONALE: This review is aimed to provide knowledge on the activation mechanism and cellular role of Sirtuins and to give an update of the rapid development of Sirtuin research in female and male reproduction under physiological and pathological conditions. The final goal is to assess whether strategies aimed to improve Sirtuin expression or activity could have therapeutic potential for infertility associated with polycystic ovarian syndrome (PCOS), endometriosis, diabetes, xenobiotic stress and aging. SEARCH METHODS: The MEDLINE database was examined for peer-reviewed original articles. The following keywords were searched: 'Sirtuin', 'ovary', 'oocyte', 'ovarian follicle', 'embryo', 'endometrium', 'sperm' and 'testis'. These keywords were combined with other search phrases relevant to the topic. OUTCOMES: Our knowledge of Sirtuins in reproductive functions has grown exponentially over the last few years. The majority of the work carried out so far has focused on SIRT1 with a prevalence of studies on female reproduction. Numerous studies have provided evidence that down regulation of SIRT1 is associated with physiological or pathological reduction of ovarian reserve. SIRT1 has also been shown to regulate proliferation and apoptosis in granulosa cells whereas SIRT3 was found to promote luteinisation. Biochemical modulation of Sirtuin activity has led to discoveries of the roles of SIRT1, SIRT2, SIRT3 and SIRT6 in improving the competence of oocytes grown or matured in vitro in humans and animal models. Recently, SIRT1, SIRT2 and SIRT3 have emerged as protectors of oocyte against postovulatory aging. Transgenic models provide strong evidence that SIRT1 is involved in spermatogenesis by influencing specific functions of male germ cell, Sertoli cells and Leydig cells. When our attention moves to post-fertilization events, maternally derived SIRT3 appears crucial in the protecting early embryos against stress conditions. Finally, increasing SIRT1 activity may have the potential to ameliorate fertility in PCOS, diabetes, endometriosis, xenobiotic stress and aging. Overall, these effects have been ascribed to Sirtuin-mediated regulation of energy homoeostasis, mitochondrial biogenesis, chromatin remodelling and protection against oxidative stress. WIDER IMPLICATIONS: The present review provides challenges and opportunities to stimulate research and exploit Sirtuin-based signalling as diagnostic tools and potential targets for therapeutic applications in reproductive medicine. PMID- 29447381 TI - DNA mismatch repair and oligonucleotide end-protection promote base-pair substitution distal from a CRISPR/Cas9-induced DNA break. AB - Single-stranded oligodeoxyribonucleotide (ssODN)-mediated repair of CRISPR/Cas9 induced DNA double-strand breaks (DSB) can effectively be used to introduce small genomic alterations in a defined locus. Here, we reveal DNA mismatch repair (MMR) activity is crucial for efficient nucleotide substitution distal from the Cas9 induced DNA break when the substitution is instructed by the 3' half of the ssODN. Furthermore, protecting the ssODN 3' end with phosphorothioate linkages enhances MMR-dependent gene editing events. Our findings can be exploited to optimize efficiencies of nucleotide substitutions distal from the DSB and imply that oligonucleotide-mediated gene editing is effectuated by templated break repair. PMID- 29447382 TI - Randomized Controlled Trial of Acupuncture for Women with Fibromyalgia: Group Acupuncture with Traditional Chinese Medicine Diagnosis-Based Point Selection. AB - Background: Group acupuncture is a growing and cost-effective method for delivering acupuncture in the United States and is the practice model in China. However, group acupuncture has not been tested in a research setting. Objective: To test the treatment effect of group acupuncture vs group education in persons with fibromyalgia. Design: Random allocation two-group study with repeated measures. Setting: Group clinic in an academic health center in Portland, Oregon. Subjects: Women with confirmed diagnosis of fibromyalgia (American College of Radiology 1990 criteria) and moderate to severe pain levels. Methods: Twenty treatments of a manualized acupuncture treatment based on Traditional Chinese Medicine diagnosis or group education over 10 weeks (both 900 minutes total). Weekly Revised Fibromyalgia Impact Questionnaire (FIQR) and Global Fatigue Index at baseline, five weeks, and 10 weeks and a four-week follow-up were assessed. Results: Thirty women were recruited, with 78% reporting symptoms for longer than 10 years. The mean attendance was 810 minutes for acupuncture and 861 minutes for education. FIQR total, FIQR pain, and Global Fatigue Index all had clinically and statistically significant improvement in the group receiving acupuncture at end of treatment and four weeks post-treatment but not in participants receiving group education between groups. Conclusions: Compared with education, group acupuncture improved global symptom impact, pain, and fatigue. Furthermore, it was a safe and well-tolerated treatment option, improving a broader proportion of patients than current pharmaceutical options. PMID- 29447385 TI - Response to Mikel. PMID- 29447384 TI - Antimicrobial Prophylaxis with Combat-Related Open Soft-Tissue Injuries. AB - Introduction: All Department of Defense (DoD) guidance documents recommend cefazolin or clindamycin as post-trauma antibiotic prophylaxis for open soft tissue injuries. Although not advocated, some patients with open soft-tissue injuries also received expanded Gram-negative coverage (EGN) prophylaxis based on the judgment of front-line trauma providers. During the study period, revised guidelines in 2011/2012 re-emphasized recommendations for using cefazolin or clindamycin, and stewardship efforts in the DoD trauma community aimed to reduce the practice of adding EGN to guideline-recommended antibiotic prophylaxis. Our objective was to examine antibiotic utilization among wounded military personnel with open extremity soft-tissue injuries over a 5-yr period and assess the impact on infectious outcomes in patients who received EGN prophylaxis versus guideline directed prophylaxis. Methods: The study population included military personnel with open extremity soft-tissue injuries sustained in Iraq and Afghanistan (2009 2014) who transferred to participating hospitals in the USA following medical evacuation. The analysis was restricted to patients who were hospitalized for at least seven days at a U.S. facility and excluded those who sustained open fractures. Post-trauma antibiotic prophylactic regimens were defined as narrow if they followed recommended guidance (e.g., IV cefazolin or clindamycin) or EGN coverage when the narrow regimen also included fluoroquinolones and/or aminoglycosides. Intravenous amoxicillin-clavulanate, which is commonly used at non-U.S. coalition theater hospitals, was also classified as narrow because it conformed to coalition antibiotic prophylaxis guidelines. This study was approved by the Infectious Disease Institutional Review Board of the Uniformed Services University of the Health Sciences. Results: A total of 287 wounded personnel with open soft-tissue injuries were assessed, of which 212 (74%) received narrow prophylaxis and 75 (26%) received EGN coverage (p < 0.001). Among patients in the narrow prophylaxis group, 81% were given cefazolin and/or clindamycin, while 19% received amoxicillin-clavulanate. In the EGN group, 88% and 12% received a fluoroquinolone and aminoglycoside, respectively. Use of EGN coverage significantly declined during the study period from 39% in 2009-2010 to 11% in 2013-2014 (p < 0.001). Approximately 3% of patients who received a narrow regimen developed an extremity skin and soft-tissue infection, while there were no skin and soft-tissue infections among patients in the EGN coverage group. Nonetheless, this was not a significant difference (p = 0.345). In addition, the proportion of non-extremity infections was not significantly different between narrow and EGN regimen groups (11% and 15%, respectively). There were also no significant differences between the narrow and EGN regimen groups related to duration of hospitalization (median of 19 versus 20 d). Conclusion: Use of non-guideline directed EGN-based post-trauma antibiotic prophylaxis does not improve infectious outcomes nor does it shorten hospital stay. PMID- 29447383 TI - Super-resolution imaging identifies PARP1 and the Ku complex acting as DNA double strand break sensors. AB - DNA double-strand breaks (DSBs) are fatal DNA lesions and activate a rapid DNA damage response. However, the earliest stage of DSB sensing remains elusive. Here, we report that PARP1 and the Ku70/80 complex localize to DNA lesions considerably earlier than other DSB sensors. Using super-resolved fluorescent particle tracking, we further examine the relocation kinetics of PARP1 and the Ku70/80 complex to a single DSB, and find that PARP1 and the Ku70/80 complex are recruited to the DSB almost at the same time. Notably, only the Ku70/80 complex occupies the DSB exclusively in the G1 phase; whereas PARP1 competes with the Ku70/80 complex at the DSB in the S/G2 phase. Moreover, in the S/G2 phase, PARP1 removes the Ku70/80 complex through its enzymatic activity, which is further confirmed by in vitro DSB-binding assays. Taken together, our results reveal PARP1 and the Ku70/80 complex as critical DSB sensors, and suggest that PARP1 may function as an important regulator of the Ku70/80 complex at the DSBs in the S/G2 phase. PMID- 29447386 TI - Kick.it: The development of an evidence-based smoking cessation smartphone app. AB - Currently, the evidence for mobile health (mHealth) smoking cessation interventions is limited and heterogeneous, warranting the need for innovative rigorously developed solutions. The aim of this study was to describe the development of a smoking cessation smartphone application (app) developed using evidence-based principles. The app (Kick.it) was designed using the Intervention Mapping framework, incorporating an extensive literature review and qualitative study, in combination with the Behavioural Change Taxonomy v1, the Theoretical Domains Framework, and the Persuasive System Design framework. Kick.it provides quit smoking education, skills training, motivational content and self-regulation functionality for smokers, as well as their social support network. By logging cravings and cigarettes smoked, users will create their own smoking profile, which will be used to provide tailored interventions. It hosts a social network to allow 24/7 social support and provides in-app tools to help with urges to smoke. The app aims to motivate smokers to retry if they slip-up or relapse, allowing them to learn from previous smoking cessation attempts. Rather than basing the app on a singular behavioral change approach, Kick.it will use elements stemming from a variety of behavioral approaches by combining methods of multiple psychological theories. The use of best-practice intervention development frameworks in conjunction with evidence-based behavioral change techniques is expected to result in a smartphone app that has an optimal chance of helping people to quit smoking. PMID- 29447388 TI - Enhancing protein fold determination by exploring the complementary information of chemical cross-linking and coevolutionary signals. AB - Motivation: Elucidation of protein native states from amino acid sequences is a primary computational challenge. Modern computational and experimental methodologies, such as molecular coevolution and chemical cross-linking mass spectrometry allowed protein structural characterization to previously intangible systems. Despite several independent successful examples, data from these distinct methodologies have not been systematically studied in conjunction. One challenge of structural inference using coevolution is that it is limited to sequence fragments within a conserved and unique domain for which sufficient sequence datasets are available. Therefore, coupling coevolutionary data with complimentary distance constraints from orthogonal sources can provide additional precision to structure prediction methodologies. Results: In this work, we present a methodology to combine residue interaction data obtained from coevolutionary information and cross-linking/mass spectrometry distance constraints in order to identify functional states of proteins. Using a combination of structure-based models (SBMs) with optimized Gaussian-like potentials, secondary structure estimation and simulated annealing molecular dynamics, we provide an automated methodology to integrate constraint data from diverse sources in order to elucidate the native conformation of full protein systems with distinct complexity and structural topologies. We show that cross linking mass spectrometry constraints improve the structure predictions obtained from SBMs and coevolution signals, and that the constraints obtained by each method have a useful degree of complementarity that promotes enhanced fold estimates. Availability and implementation: Scripts and procedures to implement the methodology presented herein are available at https://github.com/mcubeg/DCAXL.

PMID- 29447387 TI - Ezh2 promotes clock function and hematopoiesis independent of histone methyltransferase activity in zebrafish. AB - EZH2 is a subunit of polycomb repressive complex 2 (PRC2) that silences gene transcription via H3K27me3 and was shown to be essential for mammalian liver circadian regulation and hematopoiesis through gene silencing. Much less, however, is known about how Ezh2 acts in live zebrafish. Here, we show that zebrafish ezh2 is regulated directly by the circadian clock via both E-box and RORE motif, while core circadian clock genes per1a, per1b, cry1aa and cry1ab are down-regulated in ezh2 null mutant and ezh2 morphant zebrafish, and either knockdown or overexpression of ezh2 alters locomotor rhythms, indicating that Ezh2 is required for zebrafish circadian regulation. In contrast to its canonical silencing function, zebrafish Ezh2 up-regulates these key circadian clock genes independent of histone methyltransferase activity by directly binding to key circadian clock proteins. Similarly, Ezh2 contributes to hematopoiesis by enhancing expression of hematopoietic genes such as cmyb and lck. Together, our findings demonstrate for the first time that Ezh2 acts in both circadian regulation and hematopoiesis independent of silencing PRC2. PMID- 29447389 TI - Survival of adults with systemic autoimmune rheumatic diseases and pulmonary arterial hypertension after lung transplantation. AB - Objectives: Pulmonary arterial hypertension (PAH) is a major cause of morbidity and mortality in adults with systemic autoimmune rheumatic diseases (ARDs). The aim of this study was to determine whether adults with ARDs and PAH on right sided heart catheterization (ARD-PAH) have increased mortality following lung transplantation compared with those with PAH not due to an ARD. Methods: We conducted a retrospective cohort study of 93 adults with ARD-PAH and 222 adults with PAH who underwent lung transplantation in the USA between 4 May 2005 and 9 March 2015 using data from the United Network for Organ Sharing. We examined associations between diagnosis and survival after lung transplantation using stratified Cox models adjusted for potential confounding recipient factors. Results: Among adults undergoing lung transplantation in the USA, we did not detect a difference in the multivariable-adjusted mortality rate between those with ARD-PAH and those with PAH [hazard ratio 0.75 (95% CI 0.47, 1.19)]. Conclusion: The presence of an ARD was not associated with increased mortality after lung transplantation in adults with PAH. PMID- 29447390 TI - Pold3 is required for genomic stability and telomere integrity in embryonic stem cells and meiosis. AB - Embryonic stem cells (ESCs) and meiosis are featured by relatively higher frequent homologous recombination associated with DNA double strand breaks (DSB) repair. Here, we show that Pold3 plays important roles in DSB repair, telomere maintenance and genomic stability of both ESCs and spermatocytes in mice. By attempting to generate Pold3 deficient mice using CRISPR/Cas9 or transcription activator-like effector nucleases, we show that complete loss of Pold3 (Pold3-/-) resulted in early embryonic lethality at E6.5. Rapid DNA damage response and massive apoptosis occurred in both outgrowths of Pold3-null (Pold3-/-) blastocysts and Pold3 inducible knockout (iKO) ESCs. While Pold3-/- ESCs were not achievable, Pold3 iKO led to increased DNA damage response, telomere loss and chromosome breaks accompanied by extended S phase. Meanwhile, loss of Pold3 resulted in replicative stress, micronucleation and aneuploidy. Also, DNA repair was impaired in Pold3+/- or Pold3 knockdown ESCs. Moreover, Pold3 mediates DNA replication and repair by regulating 53BP1, RIF1, ATR and ATM pathways. Furthermore, spermatocytes of Pold3 haploinsufficient (Pold3+/-) mice with increasing age displayed impaired DSB repair, telomere shortening and loss, and chromosome breaks, like Pold3 iKO ESCs. These data suggest that Pold3 maintains telomere integrity and genomic stability of both ESCs and meiosis by suppressing replicative stress. PMID- 29447392 TI - Activity-dependent functions of non-electrical glial cells. AB - Electrical activity is essential for brain function. However, neurons, the electrically active cells, are less numerous than the non-electrical glial cells in the central nervous system. The non-electrical components modify the function of neural circuits, depending on the electrical neuronal activity, by wrapping synapses, myelinating axons and phagocytozing the neuronal components. Moreover, recent evidence has suggested that they contribute to neurological and psychiatric disease by regulating neuronal circuits, ultimately affecting their behaviour. In this review, we highlight the physiological functions of glial cells, particularly the electrical activity-dependent processes, to provide further insight into their role in brain function. PMID- 29447391 TI - Comparative analysis of epidermal differentiation genes of crocodilians suggests new models for the evolutionary origin of avian feather proteins. AB - The epidermis of amniotes forms a protective barrier against the environment and the differentiation program of keratinocytes, the main cell type in the epidermis, has undergone specific alterations in the course of adaptation of amniotes to a broad variety of environments and lifestyles. The epidermal differentiation complex (EDC) is a cluster of genes expressed at late stages of keratinocyte differentiation in both sauropsids and mammals. In the present study we identified and analyzed the crocodilian equivalent of the EDC. The gene complement of the EDC of both the American alligator and the saltwater crocodile were determined by comparative genomics, de novo gene prediction and identification of EDC transcripts in published transcriptome data. We found that crocodilians have an organization of the EDC similar to that of their closest living relatives, the birds, with which they form the clade Archosauria. Notable differences include the specific expansion of a subfamily of EDC genes in crocodilians and the loss of distinct ancestral EDC genes in birds. Identification and comparative analysis of crocodilian orthologs of avian feather proteins suggest that the latter evolved by cooption and sequence modification of ancestral EDC genes, and that the amplification of an internal highly cysteine enriched amino acid sequence motif gave rise to the feather component Epidermal Differentiation Cysteine Rich Protein (EDCRP) in the avian lineage. Thus, sequence diversification of EDC genes contributed to the evolutionary divergence of the crocodilian and avian integuments. PMID- 29447393 TI - Disruption of SPT23 results in increased heat sensitivity due to plasma membrane damage in Pichia pastoris. AB - The ability to adapt to environmental changes is a necessary strategy for cell survival. Spt23 is responsible for regulation of Delta-9 desaturase expression in Pichia pastoris. Disruption of SPT23 leads to a remarkable decrease in cellular unsaturated fatty acids. In this study, we found that deletion of SPT23 resulted in growth defects under high temperature culture conditions and heat treatment induced the expression of SPT23. By measuring expression changes of heat shock proteins, protein levels and cellular localization of Hsf1, it was revealed that the sensitivity of spt23Delta to high temperature was independent of the heat shock response. Addition of the osmotic stabilizer sorbitol can restore the growth defects of spt23Delta under heat conditions. In addition, loss of SPT23 led to increased plasma membrane permeability, decreased plasma membrane integrity, depolarization, ergosterol synthesis defects and cell wall component disorder, which suggested that the sensitivity to heat treatment in spt23Delta was due to plasma membrane damage. Taken together, our results give new insights into the relationship between Spt23 and high temperature environmental stress. PMID- 29447395 TI - Characteristics and Outcomes of Coronavirus Infection in Children: The Role of Viral Factors and an Immunocompromised State. AB - Background: Immunocompromised children might be predisposed to serious infections from human coronaviruses (HCoVs), including strains OC43, NL63, HKU1, and 229E; however, the virologic and clinical features of HCoV infection in immunocompromised children have not been compared to those in nonimmunocompromised children. Methods: We retrospectively analyzed a cohort of children who presented to Seattle Children's Hospital and in whom HCoV was detected by a multiplex respiratory polymerase chain reaction assay of a nasal sample between October 2012 and March 2016. Lower respiratory tract disease (LRTD) was defined as possible or definite infiltrate seen in chest imaging, need for oxygen, or abnormal lung examination in conjunction with a physician diagnosis of LRTD. We used logistic regression modeling to evaluate risk factors for LRTD and LRTD that necessitated oxygen use (severe LRTD), including an immunocompromised state, in children with HCoV infection. Results: The median ages of 85 immunocompromised and 1152 nonimmunocompromised children with HCoV infection were 6.3 and 1.6 years, respectively. The prevalence of LRTD and of severe LRTD did not differ greatly between the immunocompromised and nonimmunocompromised patients (22% vs 26% [LRTD] and 15% vs 11% [severe LRTD], respectively); however, in a multivariable model, an immunocompromised state was associated with an increased likelihood of severe LRTD (adjusted odds ratio, 2.5 [95% confidence interval, 1.2-4.9]; P = .01). Younger age, having an underlying pulmonary disorder, and the presence of respiratory syncytial virus were also associated with LRTD or severe LRTD in multivariable models. The risks of LRTD or severe LRTD did not differ among the children with different HCoV strains. Conclusions: The presence of a copathogen and host factors, including an immunocompromised state, were associated with increased risk for severe LRTD. Recognizing risk factors for severe respiratory illness might assist in risk stratification. PMID- 29447394 TI - Human La binds mRNAs through contacts to the poly(A) tail. AB - In addition to a role in the processing of nascent RNA polymerase III transcripts, La proteins are also associated with promoting cap-independent translation from the internal ribosome entry sites of numerous cellular and viral coding RNAs. La binding to RNA polymerase III transcripts via their common UUU 3'OH motif is well characterized, but the mechanism of La binding to coding RNAs is poorly understood. Using electromobility shift assays and cross-linking immunoprecipitation, we show that in addition to a sequence specific UUU-3'OH binding mode, human La exhibits a sequence specific and length dependent poly(A) binding mode. We demonstrate that this poly(A) binding mode uses the canonical nucleic acid interaction winged helix face of the eponymous La motif, previously shown to be vacant during uridylate binding. We also show that cytoplasmic, but not nuclear La, engages poly(A) RNA in human cells, that La entry into polysomes utilizes the poly(A) binding mode, and that La promotion of translation from the cyclin D1 internal ribosome entry site occurs in competition with cytoplasmic poly(A) binding protein (PABP). Our data are consistent with human La functioning in translation through contacts to the poly(A) tail. PMID- 29447397 TI - Barriers and facilitators of diabetes services in Nepal: a qualitative evaluation. AB - For the past three decades, the burden of diabetes in Nepal has been steadily increasing, with an estimated 3% annual increase since the year 2000. Although the burden is increasing, the methods of addressing the challenge have remained largely unchanged. This study sought to assess the current state of diabetes services provided by health facilities and to identify the major barriers that people with diabetes commonly face in Nepal. For this qualitative study, we selected five health facilities of varying levels and locations. At each site, we employed three unique methods: a process evaluation of the diabetes treatment and prevention services available, in-depth interviews with patients and focus group discussions with community members without diabetes. We used thematic analysis to analyse the data. Our findings were organized into the five categories of the Ecological Model: Individual, Interpersonal, Organizational, Community and Public Policy. Sub-optimal knowledge and behaviors of patients often contributed to poor diabetes management, especially related to diet control, physical activity and initiation of drug treatment. Social support was often lacking. Organizational challenges included health provider shortages, long wait times, high patient loads and minimal time available to spend with patients, often resulting in incomprehensive care. Public policy challenges include limited services in rural settings and financial burden. The scarcity of financial and human resources for health in Nepal often results in the inability of the current healthcare system to provide comprehensive prevention and management services for chronic diseases. A multilevel, coordinated approach is necessary to address these concerns. In the short-term, adding community-based supplementary solutions outside of the traditional hospital-based model could help to increase access to affordable services. PMID- 29447398 TI - Secular Trends in the Physical Fitness of United States Army Infantry Units and Infantry Soldiers, 1976-2015. AB - Introduction: The purpose of this investigation was to examine changes over time in the physical fitness of the United States (US) Army infantry. A systematic review was conducted to identify and analyze articles and databases that reported on physical characteristics (height, weight, and body mass index) and/or Army Physical Fitness Test (APFT) scores of male infantrymen or men in infantry units. Materials and Methods: The National Library of Medicine's PubMed and the Defense Technical Information Center were searched using specific keywords. Reference lists of obtained articles, specific author searches, contact with authors, and secondary analysis of available databases enhanced the search. Studies and databases were selected if they involved infantry soldiers or soldiers in infantry units and provided a quantitative assessment of at least one physical characteristic or APFT measure. Average values for each measure were obtained, plotted by the year of data collection, and fitted to linear regression models. Results: Thirty-one articles and five available databases met the review criteria encompassing years 1976-2015. Regression analysis suggested a small temporal increase in height for infantry soldiers (2%) and soldiers in infantry units (1%). Body weight and body mass index increased over the period (9-15%) in both groups. APFT performance of infantry soldiers was generally higher than that of infantry units. There was little change in APFT performance over the period for infantry soldiers. For soldiers in infantry units, push-up performance changed little over time, whereas sit-up performance increased (8%) and two-mile run performance decreased (8%). Conclusion: Over the surveyed period, body weight and body mass index increased in US Army infantry soldiers and soldier in infantry units. Infantry soldier performance on the APFT appears to have been maintained over the period. For soldiers in infantry units, there has been a small improvement in sit-up performance, but lower two-mile run performance. PMID- 29447396 TI - RNA-DNA hybrids promote the expansion of Friedreich's ataxia (GAA)n repeats via break-induced replication. AB - Expansion of simple DNA repeats is responsible for numerous hereditary diseases in humans. The role of DNA replication, repair and transcription in the expansion process has been well documented. Here we analyzed, in a yeast experimental system, the role of RNA-DNA hybrids in genetic instability of long (GAA)n repeats, which cause Friedreich's ataxia. Knocking out both yeast RNase H enzymes, which counteract the formation of RNA-DNA hybrids, increased (GAA)n repeat expansion and contraction rates when the repetitive sequence was transcribed. Unexpectedly, we observed a similar increase in repeat instability in RNase H-deficient cells when we either changed the direction of transcription replication collisions, or flipped the repeat sequence such that the (UUC)n run occurred in the transcript. The increase in repeat expansions in RNase H deficient strains was dependent on Rad52 and Pol32 proteins, suggesting that break-induced replication (BIR) is responsible for this effect. We conclude that expansions of (GAA)n repeats are induced by the formation of RNA-DNA hybrids that trigger BIR. Since this stimulation is independent of which strand of the repeat (homopurine or homopyrimidine) is in the RNA transcript, we hypothesize that triplex H-DNA structures stabilized by an RNA-DNA hybrid (H-loops), rather than conventional R-loops, could be responsible. PMID- 29447399 TI - The Relationship Between Soldier Performance on the Two-Mile Run and the 20-m Shuttle Run Test. AB - Background: The 20-m shuttle run test (MSRT) is a common field test used to measure aerobic fitness in controlled environments. The U.S. Army currently assesses aerobic fitness with the two-mile run (TMR), but external factors may impact test performance. The aim of this study is to examine the relationship between the Army Physical Fitness Test TMR performance and the MSRT in military personnel. Methods: A group of 531 (403 males and 128 females) active duty soldiers (age: 24.0 +/- 4.1 years) performed the MSRT in an indoor facility. Heart rate was monitored for the duration of the test. Post-heart rate and age predicted maximal heart rate were utilized to determine near-maximal performance on the MSRT. The soldiers provided their most recent Army Physical Fitness Test TMR time (min). A Pearson correlation and multiple linear regression analyses were performed to examine the relationship between TMR time (min) and MSRT score (total number of shuttles completed). The study was approved by the Human Use Review Committee at the U.S. Army Research Institute of Environmental Medicine, Natick, Massachusetts. Findings: A significant, negative correlation exists between TMR time and MSRT score (r = -0.75, p < 0.001). Sex and MSRT score significantly predicted TMR time (adjusted R2 = 0.65, standard error of estimate = 0.97, p < 0.001) with a 95% ratio limits of agreement of +/-12.6%. The resulting equation is: TMR = 17.736-2.464 * (sex) - 0.050 * (MSRT) - 0.026 * (MSRT * sex) for predicted TMR time. Males equal zero, females equal one, and MSRT score is the total number of shuttles completed. Discussion: The MSRT is a strong predictor of the TMR and should be considered as a diagnostic tool when assessing aerobic fitness in active duty soldiers.

AB - Background: Superficial fungal foot infection is one of the most important dermatological diseases currently affecting military personnel. Many Thai naval rating cadets are found to suffer from superficial fungal foot infections and their sequels. Objective: To investigate prevalence, potent risk factors, responding pathogens and clinical correlation of superficial fungal foot infection in Thai naval rating cadets training in Naval rating school, Sattahip, Thailand. Materials and Methods: This cross-sectional study was performed in August 2015. Validated structured questionnaire was used regarding information about behaviors and clinical symptoms. Quality of life was assessed by Dermatology Quality of Life Index (DLQI) questionnaire and clinical presentation demonstrated by Athlete's foot severity score (AFSS). Laboratory investigations including direct microscopic examination and fungal culture were performed and recorded. All of the participants were informed and asked for their consent. Results: A total of 788 Thai naval rating cadets with a mean age of 19 yr were enrolled. There were 406 (51.5%) participants suspected of fungal skin infection from questionnaire screening. After clinical examination, 303 participants (38.5%) were found to have foot lesions (AFSS >=1). Superficial fungal foot infection was diagnosed with microscopic examination and fungal culture in 57 participants, giving a point prevalence of 7.2%. Tinea pedis was diagnosed in 54 participants with the leading causative organism being Trichophyton mentagrophytes (52.8%). Other 3 participants were diagnosed as cutaneous candidiasis. Wearing combat shoes more than 8 h was found to be a predisposing factor (p = 0.029), taking a shower less than two times a day (p = 0.008), and wearing sandals during shower (p = 0.055) was found to be protective against infection. Most fungal feet infection cases noticed their feet abnormalities (p < 0.001) including scales (p < 0.001), vesicles (p = 0.003) and maceration at interdigital web spaces (p < 0.001). Mean DLQI in superficial fungal foot infection cases was 3.35. Participants who had foot lesions (AFSS >=1) were concerned of their foots unpleasant odor demonstrated significantly higher mean DLQI than those without odor (4.2 vs. 2.28; p < 0.001). Conclusion: Superficial fungal foot infection is found as 7.2% of naval rating cadets. Wearing combat shoes more than 8 h was found to be a predisposing factor. In addition to skin manifestations including scales, vesicles, and maceration, superficial fungal foot infection also exhibited an unpleasant foot odor which affected quality of life. Self-foot-examination and life style modification should be promoted to prevent fungal infection. PMID- 29447401 TI - RaMWAS: fast methylome-wide association study pipeline for enrichment platforms. AB - Motivation: Enrichment-based technologies can provide measurements of DNA methylation at tens of millions of CpGs for thousands of samples. Existing tools for methylome-wide association studies cannot analyze datasets of this size and lack important features like principal component analysis, combined analysis with SNP data and outcome predictions that are based on all informative methylation sites. Results: We present a Bioconductor R package called RaMWAS with a full set of tools for large-scale methylome-wide association studies. It is free, cross platform, open source, memory efficient and fast.

PMID- 29447402 TI - Intraoperative Endotracheal Cuff Pressure Study: How Education and Availability of Manometers Help Guide Safer Pressures. AB - Introduction: Endotracheal intubation is a medical procedure that is often indicated in both the perioperative and critical care environments. Cuffed endotracheal tubes (ETT) allow for safer and more efficient delivery of positive pressure ventilation, as well as create a barrier to reduce the risk of micro aspiration and anesthetic pollution in the operating room environment. Over inflation of the endotracheal cuff can lead to serious and harmful sequelae. This study aimed to assess if departmental education paired with ready access to a manometer to assess cuff pressure would result in an improvement in the proportion of ETT cuff pressures in the goal range. Materials and Methods: A quality improvement study was conducted at the San Antonio Military Medical Center (SAMMC; Department of Defense hospital in San Antonio, TX). The initiative was divided into three key periods: pre-implementation, implementation, and post implementation. During the pre-implementation period, ETT cuff pressures were obtained to assess the baseline state of ETT cuff pressures for patients in the operating room; the proportion of in-range (20-30 cmH2O) pressures was calculated. During the implementation phase, operating rooms were equipped with manometers and anesthesia departmental education was performed regarding the use of the manometers. Three months later, post-implementation cuff pressures were measured in the OR, and the proportion of in-range pressures was again calculated. Results: The pre-implementation data showed an average cuff pressure of 48.92 cmH2O and a median of 38.5 cmH2O. Of the 100 pre-implementation pressures, 20 were in the goal range. Post-implementation data had an average cuff pressure of 41.96 cmH2O and a median of 30 cmH2O. A chi-squared test of pressures in the safe range from the pre-implementation versus post implementation values yielded a highly significant p-value of 0.0003. Conclusion: The data from this study clearly demonstrated a statistically significant improvement in the proportion of in-range cuff pressures following the quality improvement initiative. This study supports the use of department-wide education and the availability of manometers in each OR to yield safer cuff pressures for intubated patients. This study did not aim to determine an optimal ETT cuff pressure, but utilized data already available to determine a safe cuff pressure. Further research needs to be performed to assess whether routine monitoring of cuff pressure results in improved patient outcomes. PMID- 29447403 TI - Assessment of data quality and reporting systems for underserved populations: the case of integrated community case management programs in Nigeria. AB - Decision makers are searching for reliable data and best practices to support the implementation and scale-up of the integrated community case management (iCCM) programs in underserved areas to reduce under-five mortality in low-income countries. This study assesses data quality and reporting systems of the World Health Organization supported Rapid Access Expansion program implementing iCCM in Abia and Niger States, Nigeria. This cross-sectional study used data from 16 primary health facilities in both states. Data were collected through review of registers and monthly summary reports of 140 community-oriented resource persons (CORPs), assessments of the five dimensions of the data reporting systems and 46 key informant interviews with stakeholders. Data quality was assessed by availability, completeness and consistency. Each component of the reporting system was assessed on a 3-point scale (weak, satisfactory and strong). Results show that both the structure, functions and capabilities, as well as data collection and reporting tools dimensions of the reporting system were strong, scoring (2.80, 2.73) for Abia and (2.88, 2.75) for Niger, respectively. Data management processes and links with national reporting system components scored low 2 s, indicating fair strength. Data availability, completeness and consistency were found to be good, an indication of adequate training and supervision of CORPs and community health extension workers. Indicator definitions and reporting guidelines were the weakest dimension of the system due to lack of data reporting guidelines in both states. In conclusion, the results indicate satisfactory data reporting systems and good quality data during early implementation of iCCM programs in the two states. Hence, countries planning to adopt and implement iCCM programs should first develop structures, establish national standardized tools for collecting and reporting data, provide for adequate training and supervision of community health workers and develop reporting guidelines for all reporting levels to ensure data quality. PMID- 29447404 TI - Personal network characteristics and body mass index: the role of education among Black Americans. AB - Background: Personal (i.e. egocentric) network characteristics are associated with health outcomes, including overweight and obesity. Previous research suggests educational attainment may interact with network characteristics to buffer these relationships. Limited research has examined the personal network characteristics of Black Americans, who have increased risk of overweight and obesity. The purpose of the current study was to examine associations between network characteristics and body mass index (BMI), and whether educational attainment modified these associations among Black Americans. Methods: In 2014, using respondent-driven sampling, we recruited 430 adult residents of eight low income neighborhoods in Greenville, SC. Self-administered questionnaires assessed structural and compositional characteristics (i.e. size, density) of respondents' personal networks, socio-demographic characteristics, and health-related behaviors and conditions. Multilevel regression models with robust sandwich estimation accounted for clustering within respondent chains. Results: Among Black adults overall, network density-the number of connections among network members-was positively associated with BMI. Higher education moderated this relationship; among Black adults with a college degree, higher network density was inversely associated with BMI. Conclusions: Our data suggest low educational attainment may reflect more homogenous and less resourceful networks. Multiple pathways are discussed for how education interacts with network density on BMI among Black Americans. PMID- 29447405 TI - The representation of vulnerable populations in quality improvement studies. AB - Purpose: A mapping review to quantify representation of vulnerable populations, who suffer from disparity and often inequitable healthcare, in quality improvement (QI) research. Data sources: Studies published in 2004-2014 inclusive from Medline, Embase and Cochrane databases for English language research with the terms 'quality improvement' or 'quality control' or 'QI' and 'plan-do-study act' or 'PDSA' in the years 2004-2014 inclusively. Study selection: Published clinical research that was a QI-themed, as identified by its declared search terms, MESH terms, abstract or title. Data extraction: Three reviewers identified the eligible studies independently. Excluded were publications that were not trials, evaluations or analyses. Results of data synthesis: Of 2039 results, 1660 were eligible for inclusion. There were 586 (33.5%) publications that targeted a specific vulnerable population: children (184, 10.54%), mental health patients (125, 7.16%), the elderly (100, 5.73%), women (57, 3.27%), the poor (30, 1.72%), rural residents (29, 1.66%), visible minorities (27, 1.55%), the terminally ill (17, 0.97%), adolescents (16, 0.92%) and prisoners (1 study). Seventy-four articles targeted two or more vulnerable populations, and 11 targeted three population categories. On average, there were 158 QI research studies published per year, increasing from 69 in 2004 to 396 in 2014 (R2 = 0.7, P < 0.001). The relative representation of vulnerable populations had a mean of 33.58% and was stable over the time period (standard deviation (SD) = 5.9%, R2 = 0.001). Seven countries contributed to over 85% of the publications targeting vulnerable populations, with the USA contributing 62% of the studies. Conclusions: Over 11 years, there has been a marked increase in QI publications. Roughly one-third of all published QI research is on vulnerable populations, a stable proportion over time. Nevertheless, some vulnerable populations are under-represented. Increased education, resources and attention are encouraged to improve the health of vulnerable populations through focused QI initiatives. PMID- 29447406 TI - Using structural equation modelling to jointly estimate maternal and fetal effects on birthweight in the UK Biobank. AB - Background: To date, 60 genetic variants have been robustly associated with birthweight. It is unclear whether these associations represent the effect of an individual's own genotype on their birthweight, their mother's genotype, or both. Methods: We demonstrate how structural equation modelling (SEM) can be used to estimate both maternal and fetal effects when phenotype information is present for individuals in two generations and genotype information is available on the older individual. We conduct an extensive simulation study to assess the bias, power and type 1 error rates of the SEM and also apply the SEM to birthweight data in the UK Biobank study. Results: Unlike simple regression models, our approach is unbiased when there is both a maternal and a fetal effect. The method can be used when either the individual's own phenotype or the phenotype of their offspring is not available, and allows the inclusion of summary statistics from additional cohorts where raw data cannot be shared. We show that the type 1 error rate of the method is appropriate, and that there is substantial statistical power to detect a genetic variant that has a moderate effect on the phenotype and reasonable power to detect whether it is a fetal and/or a maternal effect. We also identify a subset of birthweight-associated single nucleotide polymorphisms (SNPs) that have opposing maternal and fetal effects in the UK Biobank. Conclusions: Our results show that SEM can be used to estimate parameters that would be difficult to quantify using simple statistical methods alone. PMID- 29447407 TI - The Feasibility of Venovenous ECMO at Role-2 Facilities in Austere Military Environments. AB - Introduction: Venovenous extracorporeal membrane oxygenation (VV-ECMO) has been gaining use to bridge the recovery from acute respiratory distress syndrome (ARDS) refractory to conventional treatment. However, these interventions are often limited to higher echelons of military care. We present a case of lung salvage from severe ARDS in an Afghani soldier with VV-ECMO at a Role-2 (R2) facility in an austere military environment in Afghanistan. Case: A 25-year-old Afghani soldier presented to an R2 facility with blast lung injury and multiple penetrating injuries following an explosion. The patient underwent immediate damage control laparotomy. The abdomen was left open for subsequent washouts and ongoing resuscitation. Due to his ineligibility for evacuation and worsening ARDS, despite 5 d of conventional ventilation strategies, he was started on VV ECMO. The patient had immediate improvements in oxygenation, which continued for 10 d. Moreover, he underwent three transportations to the operating room without accidental decannulation or disruption of the VV-ECMO device. Despite significant improvements, the patient expired on postoperative day 15, due to an overwhelming intra-abdominal sepsis. Conclusion: As future advancements are sought, VV-ECMO may become a consideration for casualties with severe ARDS at the point of injury and at lower echelons of military care.

PMID- 29447408 TI - Survival advantage of planned haemodialysis over peritoneal dialysis: a cohort study. AB - Background: Previous studies comparing the outcomes in haemodialysis (HD) with those in peritoneal dialysis (PD) have yielded conflicting results. Methods: The aim of the study was to compare the survival of planned HD versus PD patients in a cohort of adult incident patients who started renal replacement therapy (RRT) between 2006 and 2008 in the nationwide REIN registry (Reseau Epidemiologie et Information en Nephrologie). Patients who started RRT in emergency or stopped RRT within 2 months were excluded. Adjusted Cox models, propensity score matching and marginal structural models (MSMs) were used to compensate for the lack of randomization and provide causal inference from longitudinal data with time dependent treatments and confounders including transplant censorship, modality change over time and time-varying covariates. Results: Among a total of 13 767 dialysis patients, 13% were on PD at initiation of RRT and 87% were on HD. The median survival times were 53.5 months or 4.45 years and 38.6 months or 3.21 years for patients starting on HD and PD, respectively. Regardless of the model used, there was a consistent advantage in terms of survival for HD patients: hazard ratio (HR) 0.76 [95% confidence interval (95% CI) 0.69-0.84] with the Cox model using propensity score; HR 0.67 (95% CI 0.62-0.73) in the Cox model with censorship for each treatment change; and HR 0.82 (95% CI 0.69-0.97) with MSMs. However, MSMs tended to reduce the survival gap between PD and HD patients. Conclusion: This large cohort study using various statistical methods to minimize the bias appears to demonstrate a better survival in planned HD than in PD. PMID- 29447410 TI - Practical recommendations for the evaluation of improvement initiatives. AB - A lack of clear guidance for funders, evaluators and improvers on what to include in evaluation proposals can lead to evaluation designs that do not answer the questions stakeholders want to know. These evaluation designs may not match the iterative nature of improvement and may be imposed onto an initiative in a way that is impractical from the perspective of improvers and the communities with whom they work. Consequently, the results of evaluations are often controversial, and attribution remains poorly understood. Improvement initiatives are iterative, adaptive and context-specific. Evaluation approaches and designs must align with these features, specifically in their ability to consider complexity, to evolve as the initiative adapts over time and to understand the interaction with local context. Improvement initiatives often identify broadly defined change concepts and provide tools for care teams to tailor these in more detail to local conditions. Correspondingly, recommendations for evaluation are best provided as broad guidance, to be tailored to the specifics of the initiative. In this paper, we provide practical guidance and recommendations that funders and evaluators can use when developing an evaluation plan for improvement initiatives that seeks to: identify the questions stakeholders want to address; develop the initial program theory of the initiative; identify high-priority areas to measure progress over time; describe the context the initiative will be applied within; and identify experimental or observational designs that will address attribution. PMID- 29447412 TI - Service Models for Urgent and Emergency Psychiatric Care: An Overview. AB - There is variation in the way mental health services respond to urgent and emergency presentations, with few evidence-based models reported in the literature, and no agreed on best practice models. To inform the development of urgent and emergency psychiatric care models, a literature review was performed. The review sought to identify strengths and critiques of varying models, evidence gaps, and areas for future research. After review, significant variation was found in the design and scope of urgent and emergency care models. Most models are either community or hospital based, with few integrated models that span community and hospital care. The development of integrated models has the potential to reduce service duplication and support a shift toward provision of least restrictive care. The overall evidence base of urgent and emergency care models is limited, with few studies in the area, and there is a need for further research.

AB - The current article presents the effects of a 90-minute staff training intervention aimed at reducing inpatient psychiatric seclusion rates through strengthened staff commitment to seclusion alternatives and improved de escalation skills. The intervention occurred at an 18-bed adult inpatient psychiatric unit whose seclusion rates in 2015 were seven times the national average. Although the project's primary outcome compared patient seclusion rates before and after the intervention, anonymous staff surveys measured several secondary outcomes. Seclusion rates were reduced from a 6-month pre-intervention average of 2.95 seclusion hours per 1,000 patient hours to a 6-month post intervention average of 0.29 seclusion hours per 1,000 patient hours, a 90.2% reduction. Completed staff surveys showed significant staff knowledge gains, non significant changes in staff attitudes about seclusion, non-significant changes in staff de-escalation skill confidence, and use of the new resource sheet by only 17% of staff. The key study implication is that time-limited, focused staff training interventions can have a measurable impact on reducing inpatient seclusion rates.

AB - Women with dissociative identity disorder (DID) are significantly more likely than other women to experience intimate partner violence (IPV). The purpose of this qualitative investigation was to explicate the experiences of women with DID who experience IPV and describe how they cope. Grounded theory was used to conduct this investigation. Purposive sampling was used to recruit participants (N = 5) for face-to-face, semi-structured interviews. Verbatim transcripts were coded and categorized, and reflective memos were developed to explicate substantive categories. Women with DID used coping strategies that were consistent with their diagnoses, such as switching and dissociating. These coping mechanisms reflect past self-preservation strategies that were developed in association with severe childhood maltreatment. Women with DID who experienced IPV sought to mitigate and safeguard themselves from danger using strategies they developed as maltreated children. Nurses can use these findings to better recognize and understand the motivations and behaviors of women with DID who experience IPV.

AB - Motivational interviewing (MI) is a therapeutic technique that has been demonstrated to increase adherence to various treatment regimens. Nonattendance at outpatient appointments is associated with read-mission to psychiatric hospitals. The purpose of the current study was to examine the effectiveness of MI in promoting treatment adherence and increasing pediatric attendance rates at patients' first follow-up appointment after inpatient admission. A sample of 111 patients discharged from one of two child and adolescent units at an urban, inpatient psychiatric hospital in Southwestern Pennsylvania participated in the MI discharge process. Compared to hospital population data from 1 month prior to the current study, the MI discharge process demonstrated an increase of approximately 10% in attendance at the scheduled follow-up appointments and a decrease of approximately 4% in cancellations and no-show appointments. It was concluded that particularly for adolescents, MI may be a valuable treatment approach grounded in partnerships with health care providers, patients, and families to enhance outpatient appointment attendance.

AB - Support and safety measures are essential for Veterans admitted to acute psychiatric units with co-occurring posttraumatic stress disorder (PTSD) and opioid use disorder (OUD) to avoid unpleasant withdrawal symptoms. A human patient simulator was used to train clinicians to recognize opioid withdrawal symptoms. Clinicians were educated to assess for opioid withdrawal symptoms using the Clinical Opiate Withdrawal Scale. Knowledge was evaluated via pre/posttest. All participants' (N = 12) posttest scores improved. Participants self-rated their perception of clinical knowledge and practice skills as higher postintervention. Veterans indicated decreased concern about opioid withdrawal symptoms and increased perception that symptoms were adequately evaluated and treated by clinicians. Overall, the intervention appeared to enhance the provision of quality care in Veterans with OUD and co-occurring PTSD on an acute inpatient psychiatric unit.

Its highest incidence is in the elderly and the immunocompromised. The initial steps in establishing a diagnosis involve CNS imaging. Familiarity with the clinical presentation is important in order to limit the risk of a nondiagnostic biopsy. In addition to confirming the diagnosis, it is wise to evaluate for extra-CNS disease. There are important differences in the presentation and evaluation of immunocompetent patients and those of immunocompromised patients; we will delineate these in this review. Appropriate initial clinical evaluations facilitate optimal therapeutic management for patients with primary CNS lymphoma. This is of particular importance because primary CNS lymphoma is a potentially curable disease, despite the high likelihood of recurrence. PMID- 29447419 TI - Fear of Cancer Recurrence: A Practical Guide for Clinicians. AB - With increasing cancer survival, fear of cancer recurrence (FCR) is becoming a prominent clinical issue. FCR is prevalent, distressing, and long-lasting, and can negatively impact patients' quality of life, use of health services, and adherence to follow-up recommendations. Novel targeted therapies may increase risk of FCR because of longer treatment duration and follow-up, increased prognostic precision, and omission of treatment based on genomic status. Oncologists can assess and screen for FCR using validated measures; provide adequate information about prognosis, signs and symptoms of recurrence, and behavioral strategies for risk reduction and follow-up; and warn patients and families that FCR may be an issue in survivorship. It is important to normalize FCR and encourage patients to discuss it if it is a concern. Patients with severe FCR should be referred to psycho-oncology staff, who can apply some of the novel psychotherapeutic interventions that have emerged to address this condition.

AB - Survivors of childhood cancer are at increased risk for late effects of cancer therapy, but evidence suggests that adherence to follow-up care is suboptimal. Here, we review the barriers to adherence, including those unique to childhood cancer survivors, and the rationale for distribution of a survivorship care plan. We also discuss advantages and potential limitations of delivering survivorship care plans via web-based platforms, and describe the unique features of one of these platforms, Passport for Care. A baseline survey directed toward survivors and conducted through Passport for Care found that a significant proportion of survivors are unaware of their specific health risks resulting from cancer and its treatment, and compared with their parents, are less afraid of the risks of recurrence and of cancer therapy-associated late effects (n = 528). Web-based platforms such as Passport for Care have enormous potential for improving access to health information, as well as for enhancing patient, family caregiver, and healthcare provider awareness of both risks of late effects and recommended surveillance. Results from this survey also suggest the potential utility of leveraging these tools to conduct additional research on consenting survivors. PMID- 29447423 TI - NK cells inhibit anti-Mycobacterium bovis BCG T cell responses and aggravate pulmonary inflammation in a direct lung infection mouse model. AB - Tuberculosis remains a threat to public health. The major problem for curing this disease is latent infection, of which the underlying mechanisms are still not fully understood. Previous studies indicate that natural killer (NK) cells do not play a role in inhibiting the growth of Mycobacterium tuberculosis in the lung, and recent studies have revealed that NK cells regulate the adaptive immunity during mycobacterial infection. By using a mouse model of direct lung infection with Mycobacterium bovis bacillus Calmette-Guerin (BCG), we found that the presence of NK cells postponed the priming and activation of T cells after BCG infection. In addition, depletion of NK cells before infection alleviated pulmonary pathology. Further studies showed that NK cells lysed BCG-infected macrophages in an NKG2D dependent manner. Thus, NK cells did not play a direct role in control BCG, but aggravated the pulmonary inflammation and impaired anti BCG T cell immunity, likely through killing BCG-infected macrophages. Our results may have important implications for the design of immune therapy to treat tuberculosis.

AB - Toxoplasma gondii is a unicellular eukaryotic pathogen that belongs to the Apicomplexa phylum, which encompasses some of the deadliest pathogens of medical and veterinary importance. The centrosome is key to the organisation and coordination of the cell cycle and division of apicomplexan parasites. The T. gondii centrosome possesses a particular bipartite structure (outer and inner cores). One of the main roles of the centrosome is to ensure proper coordination of karyokinesis. However, how these 2 events are coordinated is still unknown in T. gondii, for which the centrosome components are poorly described. To gain more insights into the biology and the composition of the T. gondii centrosome, we characterised a protein that resides at the interface of the outer and inner core centrosomes. TgCep530 is a large coiled-coil protein with an essential role in the survival of the parasite. Depletion of this protein leads to the accumulation of parasites lacking nuclei and disruption of the normal cell cycle. Lack of TgCep530 results in a discoordination between the nuclear cycle and the budding cycle that yields fully formed parasites without nuclei. TgCep530 has a crucial role in the coordination of karyokinesis and cytokinesis. PMID- 29447427 TI - Vestibulo-ocular reflex gain values in the suppression head impulse test of healthy subjects. AB - OBJECTIVE: To assess whether there are differences in vestibulo-ocular reflex (VOR) gain for suppression head impulse (SHIMP) and head impulse (HIMP) video head impulse test paradigms, and if so, what are their causes. METHODS: Prospective multicenter observational double-blind nonrandomized clinical study was performed by collecting 80 healthy subjects from four reference hospitals. SHIMP data was postprocessed to eliminate impulses in which early SHIMP saccades were detected. Differences between HIMP and SHIMP VOR gain values were statistically evaluated. Head impulse maximum velocity, gender, age, direction of impulse, and hospital center were considered as possible influential factors. RESULTS: A small significant statistical difference between HIMP and SHIMP VOR gain values was found on repeated measures analysis of variance (-0.05 +/- 0.006, P < 0.001). Optimized linear model showed a significant influence of age variable on the observed differences for HIMP and SHIMP gain values and did not find influence between gain values differences and maximum head impulse velocity. Both HIMP and SHIMP VOR gain values were significant lower (-0.09, P < 0.001) when the impulses were performed to the left side. CONCLUSION: We had observed a difference in SHIMP and HIMP gain values not adequately explained by known gain modification factors. The persistence of this slight but significant difference indicates that there are more factors causing lower SHIMP VOR gain values. This difference must to be considered in further studies as well as in the clinical SHIMP testing protocols. We hypothesized that VOR phasic response inhibition could be the underlying cause of this difference. LEVEL OF EVIDENCE: 2b. Laryngoscope, 128:2383-2389, 2018.

AB - UV-B is a high-energy component of the solar radiation perceived by the plant and induces a number of modifications in plant growth and development, including changes in flowering time. However, the molecular mechanisms underlying these changes are largely unknown. In the present work, we demonstrate that Arabidopsis plants grown under white light supplemented with UV-B show a delay in flowering time, and this developmental reprogramming is mediated by the UVR8 photoreceptor. Using a combination of gene expression analyses and UV-B irradiation of different flowering mutants, we gained insight into the pathways involved in the observed flowering time delay in UV-B-exposed Arabidopsis plants. We provide evidence that UV-B light downregulates the expression of MSI1 and CLF, two of the components of the polycomb repressive complex 2, which in consequence drives a decrease in H3K27me3 histone methylation of MIR156 and FLC genes. Modification in the expression of several flowering time genes as a consequence of the decrease in the polycomb repressive complex 2 activity was also determined. UV-B exposure of flowering mutants supports the involvement of this complex in the observed delay in flowering time, mostly through the age pathway.

AB - Arterial stiffening is a hallmark of the aging process and atherosclerosis, including peripheral arterial disease (PAD). We investigated the associations between carotid-femoral pulse wave velocity (c-fPWV), augmentation index corrected for heart rate (Aix@HR75), ankle brachial index (ABI), and subendocardial viability ratio (SEVR), an indicator of cardiac perfusion. The c fPWV, Aix@HR75, and SEVR was estimated using applanation tonometry. The ankle systolic pressure measurements for the calculation of the ABI were obtained using an 8-mHz Doppler probe. The study group included 555 subjects, mean age 63 +/- 11 years (248 PAD (ABI < 1.0), and 307 non-PAD (ABI >= 1.0 <= 1.3). After the stepwise selection process in both PAD and non-PAD patients SEVR was not related to c-fPWV and ABI (P = .154; P = .156) and (P = .101; P = .402), respectively. In PAD patients, SEVR was negatively related to Aix@HR75 (P < .0001) and aortic PP (P = .0005). In conclusion, arterial stiffness is associated with non-invasive indices of myocardial perfusion in PAD patients, suggesting a potential pathophysiological link for increased cardiovascular events.

AB - The hydrogen bonds involving sulfur in the furfuryl mercaptan monohydrate are compared with the interactions originating from the hydroxyl group in furfuryl alcohol. The dimers with water were created in a supersonic jet expansion and characterized using microwave spectroscopy and supporting molecular orbital calculations. In furfuryl alcohol-water, a single isomer is observed, in which the water molecule forms an insertion complex with two simultaneous hydrogen bonds to the alcohol (O-H???Ow ) and the ring oxygen (Ow -H???Or ). When the alcohol is replaced by a thiol group in furfuryl mercaptan-water, two isomers are observed, with the thiol group preferentially behaving as proton donor to water. The first isomer is topologically equivalent to the alcohol analog but the stronger hydrogen bond is now established by water and the ring oxygen, assisted by a thiol S-H???Ow hydrogen bond. In the second isomer the sulfur group accepts a proton from water, forming a Ow -H???S hydrogen bond. Binding energies for the mercaptan-water dimer are predicted around 12 kJ mol-1 weaker than in the alcohol hydrate (B3LYP-D3(BJ)). The non-covalent interactions in the furfuryl dimers are dominantly electrostatic according to a SAPT(0) energy decomposition, but with increasing dispersion components in the mercaptan dimers, which are larger for the isomer with the weaker Ow -H???S interaction.

PMID- 29447430 TI - Aucubin protects against pressure overload-induced cardiac remodelling via the beta3 -adrenoceptor-neuronal NOS cascades. AB - BACKGROUND AND PURPOSE: Aucubin, the predominant component of Eucommia ulmoides Oliv., has been shown to have profound effects on oxidative stress. As oxidative stress has previously been demonstrated to contribute to acute and chronic myocardial injury, we tested the effects of aucubin on cardiac remodelling and heart failure. EXPERIMENTAL APPROACH: Initially, H9c2 cardiomyocytes and neonatal rat cardiomyocytes pretreated with aucubin (1, 3, 10, 25 and 50 MUM) were challenged with phenylephrine. Secondly, the transverse aorta was constricted in C57/B6 and neuronal NOS (nNOS)-knockout mice, then aucubin (1 or 5 mg.kg-1 body weight day-1 ) was injected i.p. for 25 days. Hypertrophy was evaluated by assessing morphological changes, echocardiographic parameters, histological analyses and hypertrophic markers. Oxidative stress was evaluated by examining ROS generation, oxidase activity and NO generation. NOS expression was determined by Western blotting. KEY RESULTS: Aucubin effectively suppressed cardiac remodelling; in mice, aucubin substantially inhibited pressure overload-induced cardiac hypertrophy, fibrosis and inflammation, whereas knocking out nNOS abolished these cardioprotective effects of aucubin. Blocking or knocking down the beta3 -adrenoceptor abolished the protective effects of aucubin in vitro. Furthermore, aucubin enhanced the protective effects of a beta3 -adrenoceptor agonist in vitro by increasing cellular cAMP levels, whereas treatment with an adenylate cyclase (AC) inhibitor abolished the cardioprotective effects of aucubin. CONCLUSIONS AND IMPLICATIONS: Aucubin suppresses oxidative stress during cardiac remodelling by increasing the expression of nNOS in a process that requires activation of the beta3 -adrenoceptor/AC/cAMP pathway. These findings suggest that aucubin could have potential as a treatment for cardiac remodelling and heart failure. PMID- 29447433 TI - A Step into the Future: Applications of Nanoparticle Enzyme Mimics. AB - We describe elementary concepts, up-to-date developments, and perspectives of the emerging field of nanoparticle enzyme mimics (so-called "nanozymes") at the interface of chemistry, biology, materials, and nanotechnology. The design and synthesis of functional enzyme mimics is a long-standing goal of biomimetic chemistry. Metal complexes, polymers and engineered biomolecules capturing the structure of natural enzymes or their active centers have been made to achieve high rates and enhanced selectivities. Still, the design of new "artificial enzymes" that are not related to proteins but with capacity of production and stability at industrial level, remains a goal. Inorganic nanoparticles bear this potential. Although it seems counterintuitive to compare nanoparticles and natural enzymes because they appear very different they share many common features: nano-size, irregular shape, and rich surface chemistry. These features enable nanomaterials to mimic reactions of natural enzymes. Representative examples with biomedical and environmental applications are given. PMID- 29447435 TI - Asymmetric dimethylarginine levels are associated with augmentation index across naive untreated patients with different hypertension phenotypes. AB - Asymmetric dimethylarginine (ADMA) is a robust marker of endothelial dysfunction in patients with essential hypertension. We investigated ADMA levels and their association with vascular damage in untreated hypertension. We enrolled consecutive patients with untreated, recently diagnosed hypertension and age matched normotensive individuals. 24-hour blood pressure, central hemodynamics, and arterial stiffness were recorded. A total of 311 individuals were studied: 165 with essential hypertension, 50 with masked hypertension, 25 with white-coat hypertension, and 71 normotensive individuals. ADMA levels significantly correlated with aortic augmentation index (AIx75) (r = .156, P = .006), aortic pulse pressure (r = .153, P = .007) and marginally with carotid-femoral pulse wave velocity (r = .110, P = .051), as well as with diastolic office BP. In the multivariate model, aortic AIx75 and age were the only statistically significant predictors of ADMA. This is the largest study to document an independent association between ADMA and aortic AIx75 but not with other indices of arterial stiffness. PMID- 29447434 TI - Alterations in melatonin and 5-HT signalling in the colonic mucosa of mice with dextran-sodium sulfate-induced colitis. AB - BACKGROUND AND PURPOSE: Inflammatory bowel disease (IBD) is characterized by pain, bleeding, cramping and altered gastrointestinal (GI) function. Changes in mucosal 5-HT (serotonin) signalling occur in animal models of colitis and in humans suffering from IBD. Melatonin is co-released with 5-HT from the mucosa and has a wide variety of actions in the GI tract. Here, we examined how melatonin signalling is affected by colitis and determined how this relates to 5-HT signalling. EXPERIMENTAL APPROACH: Using electroanalytical approaches, we investigated how 5-HT release, reuptake and availability as well as melatonin availability are altered in dextran sodium sulfate (DSS)-induced colitis in mice. Studies were conducted to explore if melatonin treatment during active colitis could reduce the severity of colitis. KEY RESULTS: We observed an increase in 5 HT and a decrease in melatonin availability in DSS-induced colitis. A significant reduction in 5-HT reuptake was observed in DSS-induced colitis animals. A reduction in the content of 5-HT was observed, but no difference in tryptophan levels were observed. A reduction in deoxycholic acid-stimulated 5-HT availability and a significant reduction in mechanically-stimulated 5-HT and melatonin availability were observed in DSS-induced colitis. Orally or rectally administered melatonin once colitis was established did not significantly suppress inflammation. CONCLUSION AND IMPLICATIONS: Our data suggest that DSS induced colitis results in a reduction in melatonin availability and an increase in 5-HT availability, due to a reduction/loss of tryptophan hydroxylase 1 enzyme, 5-HT content and 5-HT transporters. Mechanosensory release was more susceptible to inflammation when compared with chemosensory release. PMID- 29447436 TI - Synthesis of a Helical Bilayer Nanographene. AB - A rigid, inherently chiral bilayer nanographene has been synthesized as both the racemate and enantioenriched M isomer (with 93 % ee) in three steps from established helicenes. This folded nanographene is composed of two hexa-peri hexabenzocoronene layers fused to a [10]helicene, with an interlayer distance of 3.6 A as determined by X-ray crystallography. The rigidity of the helicene linker forces the layers to adopt a nearly aligned AA-stacked conformation, rarely observed in few-layer graphene. By combining the advantages of nanographenes and helicenes, we have constructed a bilayer system of 30 fused benzene rings that is also chiral, rigid, and remains soluble in common organic solvents. We present this as a molecular model system of bilayer graphene, with properties of interest in a variety of potential applications. PMID- 29447437 TI - J-Shaped Association Between Postoperative Levothyroxine Dosage and Fracture Risk in Thyroid Cancer Patients: A Retrospective Cohort Study. AB - Long-term administration of supraphysiologic dosages of levothyroxine can have detrimental effect on the bone. We aimed to investigate fracture incidence among post-thyroidectomy thyroid cancer patients compared with a matched comparison group, and explore the association between levothyroxine dosage and fracture risk. From the Korean National Health Insurance database, virtually all thyroid cancer patients who received thyroidectomy in Korea from January 1, 2004 to December 31, 2012 were included. Matched subjects were selected by 1:1 propensity score matching. Cox proportional hazards regression analysis was used to determine relative risk of osteoporotic fracture. Of 185,956 thyroid cancer patients identified, fracture events were observed in 1096 subjects (0.56%) over a mean 4.35 years of follow-up. Compared to the matched comparison group, thyroid cancer patients had no elevated risk of osteoporotic fracture (hazard ratio [HR] 1.03; 95% confidence interval [CI], 0.94 to 1.12); however, the highest dosage group (>=170 MUg/day) showed significantly higher risk (HR 1.25; 95% CI, 1.07 to 1.45), while the second quartile dosage group (115-144 MUg/day) showed lower risk (HR 0.71; 95% CI, 0.59 to 0.84) compared to a matched comparison group. When the second quartile dosage group was considered as reference, increased fracture risk was observed in those who took either lower (first quartile: adjusted HR 1.31; 95% CI, 1.08 to 1.59) or higher dosage of levothyroxine (third quartile: adjusted HR 1.50; 95% CI, 1.26 to 1.79; fourth quartile: adjusted HR 1.79; 95% CI, 1.51 to 2.13). Thyroid cancer patients were more likely to be treated with osteoporosis medication (HR 1.22; 95% CI, 1.18 to 1.26) than the matched comparison group. Both high and low dosage of levothyroxine treatment was associated with a higher risk for fractures in a J-shaped dose-dependent manner in post-thyroidectomy patients. Future studies are needed to determine how to optimize thyroid stimulating hormone (TSH) suppression and how to screen and manage fracture risk.

PMID- 29447438 TI - Serum uric acid is associated with incidence of heart failure with preserved ejection fraction and cardiovascular events in patients with arterial hypertension. AB - The objective of the present study was to evaluate clinical implications of serum uric acid (UA) on the progression of heart failure with preserved ejection fraction (HFpEF) in hypertensive patients. A total of 1009 adult patients with left ventricular hypertrophy and suspected left ventricular diastolic dysfunction were enrolled at our hospital from January 2008 to December 2011. With a median follow-up of 7.2 years, 136 (13.2%) patients developed new-onset HFpEF and 151 (15.0%) had major adverse cardiovascular events (MACEs). Compared with the lowest UA tertile of UA (<302 MUmol L-1 ), subjects in the highest tertile (>367 MUmol L 1 ) had a higher risk of developing new-onset HFpEF (HR: 1.761, 95% CI: 1.119 2.772, P = .015) as well as MACEs (HR: 1.664, 95% CI: 1.086-2.547, P = .019). Our findings indicate that hyperuricemia is associated with detrimental effects in terms of the incidence of new-onset HFpEF as well as MACEs in hypertensive patient. PMID- 29447439 TI - Threshold value of home pulse pressure predicting arterial stiffness in patients with type 2 diabetes: KAMOGAWA-HBP study. AB - This cross-sectional multicenter study was designed to evaluate the threshold value of home pulse pressure (PP) and home systolic blood pressure (SBP) predicting the arterial stiffness in 876 patients with type 2 diabetes. We measured the area under the receiver-operating characteristic curve (AUC) and estimated the ability of home PP to identify arterial stiffness using Youden Index defined cut-off point. The arterial stiffness was measured using the brachial-ankle pulse wave velocity (baPWV). AUC for arterial stiffness in morning PP was significantly greater than that in morning SBP (P < .001). AUC for arterial stiffness in evening PP was also significantly greater than that in evening SBP (P < .001). The optimal cut-off points for morning PP and evening PP, which predicted arterial stiffness, were 54.6 and 56.9 mm Hg, respectively. Our findings indicate that we should pay more attention to increased home PP in patients with type 2 diabetes.

PMID- 29447441 TI - Design factors of femur fracture fixation plates made of shape memory alloy based on the Taguchi method by finite element analysis. AB - This study proposed a way to design femur fracture fixation plates made of shape memory alloy based on computed tomography (CT) images of Korean cadaveric femurs. To this end, 3 major design factors of femur fracture fixation plates (circumference angle, thickness, and inner diameter) were selected based on the contact pressure when a femur fracture fixation plate was applied to a cylinder model using the Taguchi method. Then, the effects of the design factors were analyzed. It was shown that the design factors were statistically significant at a level of p = 0.05 concerning the inner diameter and the thickness. The factors affecting the contact pressure were inner diameter, thickness, and circumference angle, in that order. Particularly, in the condition of Case 9 (inner diameter 27 mm, thickness 2.4 mm, and circumference angle 270 degrees ), the max. average contact pressure was 21.721 MPa, while the min. average contact pressure was 3.118 MPa in Case 10 (inner diameter 29 mm, thickness 2.0 mm, and circumference angle 210 degrees ). When the femur fracture fixation plate was applied to the cylinder model, the displacement due to external sliding and pulling forces was analyzed. As a result, the displacement in the sliding condition was at max. 3.75 times greater than that in the pulling condition, which indicated that the cohesion strength between the femur fracture fixation plate and the cylinder model was likely to be greater in the pulling condition. When a human femur model was applied, the max. average contact pressure was 10.76 MPa, which was lower than the yield strength of a human femur (108 MPa). In addition, the analysis of the rib behaviors of the femur fracture fixation plate in relation to the recovery effect of the shape memory alloy showed that the rib behaviors varied depending on the arbitrarily curved shapes of the femur sections. PMID- 29447442 TI - Phenolic Group of alpha-Tocopherol Anchors at the Lipid-Water Interface of Fully Saturated Membranes. AB - alpha-Tocopherol is considered to carry on a very important role as an antioxidant for membranes and lipoproteins and other biological roles as membrane stabilizers and bioactive lipids. Given its essential role, it is very important to fully understand its location in the membrane. In this work, the vertical location of vitamin E in saturated membranes has been studied using biophysical techniques. Small- and wide-angle X-ray diffraction experiments show that alpha tocopherol alters the water layer between bilayers in both 1,2-dimyristoyl- sn glycero-3-phosphocholine (DMPC) and 1,2-dipalmitoyl- sn-glycero-3-phosphocholine (DPPC), indicating its proximity to this surface. The quenching of the intrinsic fluorescence of alpha-tocopherol indicates a low quenching efficiency by acrylamide and a higher quenching by 5-doxyl-PC than by 9- and 16-doxyl-PC. These results suggest that in both DMPC and DPPC membranes, the chromanol ring is not far away from the surface of the membrane but within the bilayer. 1H nuclear Overhauser enhancement spectroscopy magic-angle spinning-nuclear magnetic resonance studies showed that alpha-tocopherol is localized in a similar manner in DMPC and DPPC membranes, with the chromanol ring embedded in the upper part of the hydrophobic bilayer. Using attenuated total reflection-Fourier transform infrared spectroscopy, it was observed that the tail chain of alpha-tocopherol lies nearly parallel to the acyl chains of DMPC and DPPC. Taking these results together, it was concluded that in both DMPC and DPPC, the hydroxyl group of the chromanol ring will establish hydrogen bonding with water on the membrane surface, and the main axis of the alpha-tocopherol molecule will be perpendicular to the bilayer plane. PMID- 29447443 TI - Inhibitor Bound Dengue NS2B-NS3pro Reveals Multiple Dynamic Binding Modes. AB - Dengue virus poses a significant global health threat as the source of increasingly deleterious dengue fever, dengue hemorrhagic fever, and dengue shock syndrome. As no specific antiviral treatment exists for dengue infection, considerable effort is being applied to discover therapies and drugs for maintenance and prevention of these afflictions. The virus is primarily transmitted by mosquitoes, and infection occurs following viral endocytosis by host cells. Upon entering the cell, viral RNA is translated into a large multisubunit polyprotein which is post-translationally cleaved into mature, structural and nonstructural (NS) proteins. The viral genome encodes the enzyme to carry out cleavage of the large polyprotein, specifically the NS2B-NS3pro cofactor-protease complex-a target of high interest for drug design. One class of recently discovered NS2B-NS3pro inhibitors is the substrate-based trifluoromethyl ketone containing peptides. These compounds interact covalently with the active site Ser135 via a hemiketal adduct. A detailed picture of the intermolecular protease/inhibitor interactions of the hemiketal adduct is crucial for rational drug design. We demonstrate, through the use of protein- and ligand-detected solution-state 19F and 1H NMR methods, an unanticipated multibinding mode behavior of a representative of this class of inhibitors to dengue NS2B-NS3pro. Our results illustrate the highly dynamic nature of both the covalently bound ligand and protease protein structure, and the need to consider these dynamics when designing future inhibitors in this class. PMID- 29447444 TI - Methodology for the Preparation and Validation of Plutonium Age Dating Materials. AB - The present work describes a method for the preparation and validation of plutonium age dating reference materials. The test samples prepared in this context could be used to validate experimental protocols for determining the production date of plutonium via the 234U/238Pu, 235U/239Pu, 236U/240Pu, and 241Am/241Pu chronometers. The starting material was prepared using reactor-grade plutonium, which was purified using a dedicated method to guarantee high Pu recovery, while maximizing U and Am separation efficiencies. The U and Am separation factors were determined by the addition of high-amounts of 233U and 243Am spikes and their remeasurement in the final product. The prepared material is intended for quality control and assessment of method performance in nuclear forensics and safeguards. PMID- 29447445 TI - Electronic Exchange and Correlation in van der Waals Systems: Balancing Semilocal and Nonlocal Energy Contributions. AB - Short-range correlations in motion of electrons in matter are captured well by semilocal exchange-correlation (XC) functionals in density functional theory (DFT), but long-range correlations are neglected in such models and must be treated by van der Waals (vdW) dispersion methods. Whereas the effective range of distances at which fluctuations are correlated is usually explicit in the vdW models, the complementary range of semilocal functionals can be observed only implicitly, requiring an introduction of empirical damping functions to couple the semilocal and nonlocal contributions to the XC energy. We present a comprehensive study of the interplay between these short-range and long-range energy contributions in eight semilocal functionals (LDA, PBE, TPSS, SCAN, PBE0, B3LYP, SCAN0, M06-L) and three vdW models (MBD, D3, VV10) on noncovalently bonded organic dimers (S66*8), molecular crystals (X23), and supramolecular complexes (S12L), as well as on a series of graphene-flake dimers, covering a range of intermolecular distances and binding energies (0.5-130 kcal/mol). The binding energy profiles of many of the DFT+vdW combinations differ both quantitatively and qualitatively, and some of the qualitative differences are independent of the choice of the vdW model, establishing them as intrinsic properties of the respective semilocal functionals. We find that while the SCAN+vdW method yields a narrow range of binding-energy errors, the effective range of SCAN depends on system size, and we link this behavior to the specific dependence of SCAN on the electron localization function alpha around alpha = 1. Our study provides a systematic procedure to evaluate the consistency of semilocal XC functionals when paired with nonlocal vdW models and leads us to conclude that nonempirical generalized-gradient and hybrid functionals are currently among the most balanced semilocal choices for vdW systems. PMID- 29447446 TI - Online Proteolysis and Glycopeptide Enrichment with Thermoresponsive Porous Polymer Membrane Reactors for Nanoflow Liquid Chromatography-Tandem Mass Spectrometry. AB - In this Article, we have reported a fully automated online method to carry out proteolysis and glycopeptide enrichment in sequence for nanoflow liquid chromatography-tandem mass spectrometry (nLC-ESI-MS/MS) analysis. By implementing two serial thermoresponsive porous polymer membrane reactors (TPPMRs), in which the TPPM could be immobilized either with trypsin for proteolysis or with lectins for glycopeptide enrichment, the entire pretreatment procedure can be performed online in about an hour. The TPPM was fabricated by coating polystyrene-maleic anhydride- N-isopropylacrylamide (PS-MAn-PNIPAm), which was synthesized by reversible addition-fragmentation chain transfer polymerization, on a Nylon sheet. Because of the thermoresponsive nature of PNIPAm, it formed micelle cavities and changed its morphology at elevated temperatures, resulting in enhanced interactions between the enzyme or lectins and the proteins/peptides flowing through the membrane. The performances of the TPPMs were evaluated by varying the temperature conditions and the amount of standard proteins, showing that both proteolysis and glycopeptide enrichment with online deglycosylation were highly efficient at 37 degrees C. The developed online serial TPPMRs-nLC ESI-MS/MS method was applied to the human plasma sample (1.5 MUL) and a total of 262 N-glycopeptides could be identified from 155 glycoproteins. Thus, the present work demonstrates a fully automated high speed analytical protocol for online proteolysis and glycopeptide enrichment, which is extremely useful for analyzing small amounts of the proteome samples. PMID- 29447447 TI - DL_MG: A Parallel Multigrid Poisson and Poisson-Boltzmann Solver for Electronic Structure Calculations in Vacuum and Solution. AB - The solution of the Poisson equation is a crucial step in electronic structure calculations, yielding the electrostatic potential-a key component of the quantum mechanical Hamiltonian. In recent decades, theoretical advances and increases in computer performance have made it possible to simulate the electronic structure of extended systems in complex environments. This requires the solution of more complicated variants of the Poisson equation, featuring nonhomogeneous dielectric permittivities, ionic concentrations with nonlinear dependencies, and diverse boundary conditions. The analytic solutions generally used to solve the Poisson equation in vacuum (or with homogeneous permittivity) are not applicable in these circumstances, and numerical methods must be used. In this work, we present DL_MG, a flexible, scalable, and accurate solver library, developed specifically to tackle the challenges of solving the Poisson equation in modern large-scale electronic structure calculations on parallel computers. Our solver is based on the multigrid approach and uses an iterative high-order defect correction method to improve the accuracy of solutions. Using two chemically relevant model systems, we tested the accuracy and computational performance of DL_MG when solving the generalized Poisson and Poisson-Boltzmann equations, demonstrating excellent agreement with analytic solutions and efficient scaling to ~109 unknowns and 100s of CPU cores. We also applied DL_MG in actual large-scale electronic structure calculations, using the ONETEP linear-scaling electronic structure package to study a 2615 atom protein-ligand complex with routinely available computational resources. In these calculations, the overall execution time with DL_MG was not significantly greater than the time required for calculations using a conventional FFT-based solver. PMID- 29447448 TI - Gendered racism and the sexual and reproductive health of Black and Latina Women. AB - OBJECTIVE: To understand health disparities, it is important to use an intersectional framework that examines unique experiences of oppression faced by particular groups due to their intersecting identities and social positions linked to societal structures. We focus on Black and Latina women and their experiences with 'gendered racism' - unique forms of oppression due to the intersection of race/ethnicity and gender - to foster understanding of disparities between Black and Latina versus White women in sexual and reproductive health outcomes in the U.S. Specifically, we focus on stereotype related gendered racism (ongoing discrimination and stereotype threat based on historically-rooted stereotypes about Black and Latina women's sexuality and motherhood) and birth control-related mistrust (ongoing mistrust of the government and medical system related to birth control due to historical and current abuses). DESIGN: We analyzed data from two survey studies with adult women in New York (Study 1: paper-and-pencil community data collection, N = 135, Mage = 43.35) and across the U.S. (Study 2: online data collection, N = 343, Mage = 29.49) who were currently pregnant or had at least one child and identified as Black, Latina, or White. RESULTS: Black and Latina women reported greater frequency of and concern over stereotype-related gendered racism (F(3,131) = 17.90, p < .001 Study 1; F(3,339) = 22.23, p < .001 Study 2) and greater birth control-related mistrust (F(3,131) = 7.55, p < .001 Study 1; F(3,339) = 17.32, p < .001 Study 2) than White women did. In turn, stereotype-related gendered racism was positively associated with pregnancy-specific stress (beta = .40, p < .001 Study 1; beta = .33, p < .001 Study 2), and birth control-related mistrust was negatively associated with sexual relationship power (beta = -.19, p = .002 Study 2), which are factors known to contribute to birth outcomes and sexual risk, respectively. CONCLUSION: Findings suggest that gendered racism may play an important role in existing racial/ethnic disparities in women's sexual and reproductive health outcomes, and interventions addressing gendered racism at multiple levels are needed to promote health equity. PMID- 29447449 TI - Prognostic and Pathogenic Role of Angiopoietin-1 and -2 in Pneumonia. AB - RATIONALE: During pneumonia, pathogen-host interaction evokes inflammation and lung barrier dysfunction. Tie2 activation by angiopoietin-1 reduces, whereas Tie2 blockade by angiopoietin-2 increases, inflammation and permeability during sepsis. The role of angiopoietin-1/-2 in pneumonia remains unidentified. OBJECTIVES: To investigate the prognostic and pathogenic impact of angiopoietins in regulating pulmonary vascular barrier function and inflammation in bacterial pneumonia. METHODS: Serum angiopoietin levels were quantified in pneumonia patients of two independent cohorts (n = 148, n = 395). Human postmortem lung tissue, pneumolysin- or angiopoietin-2-stimulated endothelial cells, isolated perfused and ventilated mouse lungs, and mice with pneumococcal pneumonia were investigated. MEASUREMENTS AND MAIN RESULTS: In patients with pneumonia, decreased serum angiopoietin-1 and increased angiopoietin-2 levels were observed as compared with healthy subjects. Higher angiopoietin-2 serum levels were found in patients with community-acquired pneumonia who died within 28 days of diagnosis compared with survivors. Receiver operating characteristic analysis revealed improved prognostic accuracy of CURB-65 for 28-day survival, intensive care treatment, and length of hospital stay if combined with angiopoietin-2 serum levels. In vitro, pneumolysin enhanced endothelial angiopoietin-2 release, angiopoietin-2 increased endothelial permeability, and angiopoietin-1 reduced pneumolysin-evoked endothelial permeability. Ventilated and perfused lungs of mice with angiopoietin-2 knockdown showed reduced permeability on pneumolysin stimulation. Increased pulmonary angiopoietin-2 and reduced angiopoietin-1 mRNA expression were observed in Streptococcus pneumoniae-infected mice. Finally, angiopoietin-1 therapy reduced inflammation and permeability in murine pneumonia. CONCLUSIONS: These data suggest a central role of angiopoietin-1/-2 in pneumonia evoked inflammation and permeability. Increased angiopoietin-2 serum levels predicted mortality and length of hospital stay, and angiopoietin-1 may provide a therapeutic target for severe pneumonia.

AB - Plant glutathione S-transferases (GSTs) are integral to normal plant metabolism and biotic and abiotic stress tolerance. The GST gene family has been characterized in diverse plant species using molecular biology and bioinformatics approaches. In the current study, in silico analysis identified 44 GSTs in Vigna radiata. Of the total 44 GSTs identified, chromosomal locations of 31 GSTs were confirmed. The pI value of GST proteins ranged from 5.10 to 9.40. The predicted molecular weights ranged from 13.12 to 50 kDa. Subcellular localization analysis revealed that all GSTs were predominantly localized in the cytoplasm. The active site amino acids were confirmed to be serine in tau, phi, theta, zeta, and TCHQD; cysteine in lambda, DHAR, and omega; and tyrosine in EF1G. The gene architecture conformed to the two-exon/one-intron and three-exon/two-intron organization in the case of tau and phi classes, respectively. MEME analysis identified 10 significantly conserved motifs with the width of 8-50 amino acids. The motifs identified were either specific to a specific GST class or were shared by multiple GST classes. The results of the current study will be of potential importance in the characterization of the GST gene family in V. radiata, an economically important leguminous crop.

AB - Metastatic disease is the primary cause of death of patients with lung cancer, but the mouse models of lung adenocarcinoma do not accurately recapitulate the tumor microenvironment or metastatic disease observed in patients. In this study, we conditionally deleted E-cadherin in an autochthonous lung adenocarcinoma mouse model driven by activated oncogenic Kras and p53 loss. Loss of E-cadherin significantly accelerated lung adenocarcinoma progression and decreased survival of the mice. Kras;p53;E-cadherin mice had a 41% lung tumor burden, invasive grade 4 tumors, and a desmoplastic stroma just 8 weeks after tumor initiation. One hundred percent of the mice developed local metastases to the lymph nodes or chest wall, and 38% developed distant metastases to the liver or kidney. Lung adenocarcinoma cancer cell lines derived from these tumors also had high migratory rates. These studies demonstrate that the Kras;p53;E-cadherin mouse model better emulates the tumor microenvironment and metastases observed in patients with lung adenocarcinoma than previous models and may therefore be useful for studying metastasis and testing new lung cancer treatments in vivo. PMID- 29447460 TI - The curvilinear relationship of early-life adversity and successful aging: the mediating role of mental health. AB - OBJECTIVES: The steeling effect suggests that early-life adversity can have a beneficial impact later in life. However, little is known about its underlying mechanisms and long-term outcomes . The study aimed to examine the role of early life adversity (ELA) on successful aging, and whether this relationship can be explained by mental and physical health. METHOD: Socio-demographics, early-life adversity (ELA), individual quality of life (iQoL), and mental and physical health of 270 individuals (Mage = 66.82 years, 71.5% female) were assessed. Polynomial regressions and mediation analyses were conducted. RESULTS: Significant inverse U-shaped associations were found between ELA and iQoL (beta = -.59, p = .005) and between ELA and mental health (beta = -.64, p = .002), but not between ELA and physical health. Furthermore, mental health significantly mediated the relationship between ELA and iQoL (b = -.84, BCa CI [-1.66, -.27]). CONCLUSION: Highest level of individual quality of life (i.e. successful aging) was related to a moderate amount of ELA. Additionally, mental health significantly mediated this relationship. These findings suggest that some amount of ELA could be beneficial for successful aging. Resource-focused interventions are needed to improve health and promote successful aging for an underdetected, at-risk subgroup with low early-life adversity.

AB - OBJECTIVE: To identify ways Chinese and South Asian gay and bisexual men living in Auckland talk about issues related to sexuality and experiences of living 'gay social lives.' Results will be available to inform health policy and practice. DESIGN: A qualitative design with individual interviews and thematic analysis was used. Semi-structured digitally recorded interviews were undertaken with 27 Chinese and 17 South Asian gay and bisexual men living in Auckland. RESULTS: Four themes in the data related to talk about sexuality and living gay social lives are reported: (a) 'Happy in my skin': Being gay is Ok! (b) 'To come out or not': Managing sexual identity, (c) 'Places to go, people to see': Connecting with others, and (d) 'What's wrong with being Asian': Tolerating discrimination. CONCLUSION: There are many similarities in the ways these men talked about their identity and sexuality that can be usefully considered by health policy makers and service planners. The concept of gay (and bisexual) sexuality had some salience for the men interviewed, despite the adoption and acknowledgement of same-sex identity being a relatively new phenomenon in some Asian countries. This supports the use of these terms in local health interventions. However, as these men closely managed their gay identity and typically had not disclosed their sexuality to others, including healthcare professionals, interventions to address the skills and comfort of healthcare providers in addressing sexuality in clinical settings appear warranted to facilitate optimal healthcare. These men are not well connected with others and this has implications for HIV health promotion that is based on creating cultural norms among networks to encourage safe sex. Discrimination results in many Chinese and South Asian gay and bisexual men disengaging from connecting with others and should be addressed.

PMID- 29447461 TI - Genetic Ablation of p16INK4a Does Not Protect against Cellular Senescence in Mouse Models of Chronic Obstructive Pulmonary Disease/Emphysema. AB - Cigarette smoke (CS) affects DNA damage and cellular senescence signaling pathways in the pathogenesis of chronic obstructive pulmonary disease (COPD). p16INK4a (p16: a cyclin-dependent kinase inhibitor) is a key marker of cellular senescence, which is induced by CS in lung cells. It is thought that removal of p16 attenuates premature aging by removing senesced cells. However, the role of p16 in CS-induced stress-induced premature senescence (SIPS) and senescence associated secretory phenotype (SASP) during the development of COPD/emphysema is not known. We hypothesize that p16 regulates cellular senescence and DNA damage/repair molecular signaling targets during chronic CS-induced inflammation and airspace enlargement in mouse models of COPD. We used p16 global knockout (KO) and p16 lung epithelial cell-specific KO (p16CreCC10) mice to determine whether p16 removal in lung epithelium augments or protects against cellular senescence (SIPS and SASP) in chronic CS- and elastase-induced development of COPD/emphysema in mice. p16 KO mice exposed to chronic CS and p16 lung epithelial cell-specific KO mice exposed to elastase did not show attenuation of lung inflammation, altered lung function, or airspace enlargement. p16 KO and p16CreCC10 exposed to CS and elastase showed increases in lung senescence associated beta-galactosidase activity. Thus, removal of p16-positive cells did not protect against airspace enlargement and decline in lung function induced in COPD mouse models. Our findings suggest that p16 is not the only key player associated with CS-induced cellular senescence phenotypes (SIPS and SASP), decline in lung function, and airspace enlargement in COPD/emphysema.

PMID- 29447469 TI - Tricin isolated from Allium atroviolaceum potentiated the effect of docetaxel on PC3 cell proliferation: role of miR-21. AB - For more effectiveness and overcoming the drug resistance Chemotherapy agents, the combination treatment is raised. Flavonoids with different anti-cancer effects are an appropriate choice as lead compounds. Over expressed MiR-21 in prostate cancer is associated with metastasis and drug resistance to chemotherapy with Docetaxel. In this study, the anticancer effect of 4', 5, 7-Trihydroxy-3', 5'-dimethoxyflavone (Tricin) was investigated with Docetaxel on PC3 cell line. Tricin was initially isolated from the Allium atroviolaceum by column chromatography and recrystallization method. The chemical structure of isolate was elucidated by spectroscopic techniques. IC50 of Tricin and Docetaxel were assessed 117.5 +/- 4.4 MUM and 0.1 +/- 0.02 nM by MTT assay, respectively. Analysis of results indicates the synergistic effect of combination therapy on decreased proliferation. MiR-21 in treated cells with Tricin significantly decreased compared to control cells. So, Tricin can be effective in the reduction of metastasis and drug resistance of Docetaxel. PMID- 29447471 TI - Anti-infection silver nanoparticle immobilized biomaterials facilitated by argon plasma grafting technology. AB - Many research groups have attained slow, persistent, continuous release of silver ions through careful experimental design using existing methods. Such methods effectively kill planktonic bacteria and therefore prevent surface adhesion of pathogens. However, the resultant modified coatings cannot provide long-term antibacterial efficacy due to sustained anti-microbial release. In this study, the anti-infection activity of AgNP immobilized biomaterials was evaluated, facilitated by argon plasma grafting technology and activated by bacterial colonization. The modified materials generated in this study showed excellent specificity and were active against both Gram-positive and Gram-negative biofilm forming bacteria, including methicillin-resistant Staphylococcus aureus, Staphylococcus epidermidis, and Escherichia coli. The anti-infection biomaterials developed in this study demonstrate several attractive advantages in comparison to traditional anti-bacterial surfaces loaded with antibiotics or other types of antibacterial agents and include (1) broad spectrum of activity against antibiotic resistant bacteria, (2) the unlikelihood of bacterial resistance, (3) specificity, (4) biocompatibility, and (5) stability. PMID- 29447472 TI - Viable Cell Culture Banking for Biodiversity Characterization and Conservation. AB - Because living cells can be saved for indefinite periods, unprecedented opportunities for characterizing, cataloging, and conserving biological diversity have emerged as advanced cellular and genetic technologies portend new options for preventing species extinction. Crucial to realizing the potential impacts of stem cells and assisted reproductive technologies on biodiversity conservation is the cryobanking of viable cell cultures from diverse species, especially those identified as vulnerable to extinction in the near future. The advent of in vitro cell culture and cryobanking is reviewed here in the context of biodiversity collections of viable cell cultures that represent the progress and limitations of current efforts. The prospects for incorporating collections of frozen viable cell cultures into efforts to characterize the genetic changes that have produced the diversity of species on Earth and contribute to new initiatives in conservation argue strongly for a global network of facilities for establishing and cryobanking collections of viable cells. PMID- 29447473 TI - Impact of Micronutrients on the Immune Response of Animals. AB - Vitamins and minerals (micronutrients) play an important role in regulating and shaping an immune response. Deficiencies generally result in inadequate or dysregulated cellular activity and cytokine expression, thereby affecting the immune response. Decreased levels of natural killer, granulocyte, and phagocytic cell activity and T and B cell proliferation and trafficking are associated with inadequate levels of micronutrients, as well as increased susceptibility to various adverse health conditions, including inflammatory disorders, infection, and altered vaccine efficacy. In addition, most studies of micronutrient modulation of immune responses have been done in rodents and humans, thus limiting application to the health and well-being of livestock and companion animals. This exploratory review elucidates the role of vitamins and minerals on immune function and inflammatory responses in animals (pigs, dogs, cats, horses, goats, sheep, and cattle), with reference to rodents and humans. PMID- 29447474 TI - Introduction. PMID- 29447475 TI - The Divergent Genomes of Teleosts. AB - Boasting nearly 30,000 species, teleosts account for half of all extant vertebrates and approximately 98% of all ray-finned fish species (Actinopterygii). Teleosts are also the largest and most diverse group of vertebrates, exhibiting an astonishing level of morphological, physiological, and behavioral diversity. Previous studies had indicated that the teleost lineage has experienced an additional whole-genome duplication event. Recent comparative genomic analyses of teleosts and other bony vertebrates using spotted gar (a nonteleost ray-finned fish) and elephant shark (a cartilaginous fish) as outgroups have revealed several divergent features of teleost genomes. These include an accelerated evolutionary rate of protein-coding and nucleotide sequences, a higher rate of intron turnover, loss of many potential cis regulatory elements and shorter conserved syntenic blocks. A combination of these divergent genomic features might have contributed to the evolution of the amazing phenotypic diversity and morphological innovations of teleosts. PMID- 29447477 TI - Inhibition of the lethality of Shiga-like toxin-1 by functional gold nanoparticles. AB - Escherichia coli O157:H7 is a pathogen, which can generate Shiga-like toxins (SLTs) and cause hemolytic-uremic syndrome. Foodborne illness outbreaks caused by E. coli O157:H7 have become a global issue. Since SLTs are quite toxic, effective medicines that can reduce the damage caused by SLTs should be explored. SLTs consist of a single A and five B subunits, which can inhibit ribosome activity for protein synthesis and bind with the cell membrane of host cells, respectively. Pigeon ovalbumin (POA), i.e. a glycoprotein, is abundant in pigeon egg white (PEW) proteins. The structure of POA contains Gal-alpha(1->4)-Gal beta(1->4)-GlcNAc ligands, which have binding affinity toward the B subunit in SLT type-1 (SLT-1B). POA immobilized gold nanoparticles (POA-Au NPs) can be generated by reacting PEW proteins with aqueous tetrachloroauric acid in one-pot. The generated POA-Au NPs have been demonstrated to have selective trapping capacity toward SLT-1B previously. Herein, we explore that POA-Au NPs can be used as protective agents to neutralize the toxicity of SLT-1 in SLT-1-infected model cells. The results show that the cells can be completely rescued when a sufficient amount of POA-Au NPs is used to treat the SLT-1-infected cells within 1 h. PMID- 29447476 TI - Sequencing and characterization of lncRNAs in the breast muscle of Gushi and Arbor Acres chickens. AB - Chicken muscle quality is one of the most important factors determining the economic value of poultry, and muscle development and growth are affected by genetics, environment, and nutrition. However, little is known about the molecular regulatory mechanisms of long non-coding RNAs (lncRNAs) in chicken skeletal muscle development. Our study aimed to better understand muscle development in chickens and thereby improve meat quality. In this study, Ribo Zero RNA-Seq was used to investigate differences in the expression profiles of muscle development related genes and associated pathways between Gushi (GS) and Arbor Acres (AA) chickens. We identified two muscle tissue specific expression lncRNAs. In addition, the target genes of these lncRNAs were significantly enriched in certain biological processes and molecular functions, as demonstrated by Gene Ontology (GO) analysis, and these target genes participate in five signaling pathway, as revealed by an analysis of the Kyoto Encyclopedia of Genes and Genomes (KEGG) database. Taken together, these data suggest that different lncRNAs might be involved in regulating chicken muscle development and growth and provide new insight into the molecular mechanisms of lncRNAs. PMID- 29447478 TI - Dendritic platforms for biomimicry and biotechnological applications. AB - Dendrimers, commonly referred to as polymeric trees, offer endless opportunities for biotechnological and biomedical applications. By controlling the type, length, and molecular weight of the core, branches and end groups, respectively, the chemical functionality and topology of dendrimeric archetypes can be customized which further can be applied to achieve required solubility, biodegradability, diagnosis and other applications. Given the physicochemical variability of the dendrimers and their hybrids, this review attempts to discuss a full spectrum of recent advances and strides made by these "perfectly designed structures". An extensive biotech/biomimicry application profiling of dendrimers is provided with focus on complex archetypical designs such as protein biomimicry (angiogenic inhibitors, regenerative hydroxyapatite and collagen) and biotechnology applications. In terms of biotechnological advances, dendrimers have provided distinctive advantages in the fields of biocatalysis, microbicides, artificial lights, mitochondrial function modulation, vaccines, tissue regeneration and repair, antigen carriers and even biosensors. In addition, this review provides overview of the extensive chemo-functionalization opportunities available with dendrimers which makes them a perfect candidate for forming drug conjugates, protein hybrids, bio mimics, lipidic derivatives, metal deposits and nanoconjugates thereby making them the most multifunctional platforms for diverse biotechnological applications. PMID- 29447479 TI - Two new lignans from Horsfieldia kingii. AB - Two new dibenzylbutyrolactol lignans and three known dibenzylbutyrolactone lignans were isolated from the twigs and leaves of Horsfieldia kingii. Their structures were elucidated by spectroscopic analysis. Cytotoxicity evaluation of these compounds against five human tumour lines showed no inhibitory effects. PMID- 29447480 TI - Intramuscular Distribution of the Abducens Nerve in the Lateral Rectus Muscle for the Management of Strabismus. AB - AIMS: To elucidate the intramuscular distribution and branching patterns of the abducens nerve in the lateral rectus (LR) muscle so as to provide anatomical confirmation of the presence of compartmentalization, including for use in clinical applications such as botulinum toxin injections. METHODS: Thirty whole mount human cadaver specimens were dissected and then Sihler's stain was applied. The basic dimensions of the LR and its intramuscular nerve distribution were investigated. The distances from the muscle insertion to the point at which the abducens nerve enters the LR and to the terminal nerve plexus were also measured. RESULTS: The LR was 46.0 mm long. The abducens nerve enters the muscle on the posterior one-third of the LR and then typically divides into a few branches (average of 1.8). This supports a segregated abducens nerve selectively innervating compartments of the LR. The intramuscular nerve distribution showed a Y-shaped ramification with root-like arborization. The intramuscular nerve course finished around the middle of the LR (24.8 mm posterior to the insertion point) to form the terminal nerve plexus. This region should be considered the optimal target site for botulinum toxin injections. We have also identified the presence of an overlapping zone and communicating nerve branches between the neighboring LR compartments. CONCLUSION: Sihler's staining is a useful technique for visualizing the entire nerve network of the LR. Improving the knowledge of the nerve distribution patterns is important not only for researchers but also clinicians to understand the functions of the LR and the diverse pathophysiology of strabismus. PMID- 29447481 TI - Regularity changes of the retinal nerve fiber layer and macular ganglion cell complex in patients with the amnestic mild cognitive impairment. AB - : Purpose/aim: We investigated the regularity changes of the retinal nerve fiber layer (RNFL) and macular ganglion cell complex (mGCC) of the amnestic mild cognitive impairment (aMCI) patients in this prospective cohort study. MATERIALS AND METHODS: Twenty-four aMCI patients and 30 health controls, who are more than 60 years old, were recruited into the study. The RNFL and the mGCC average thickness were measured with Fourier-domain optical coherence tomography (FD OCT). RESULTS: Compared with that in the controls, the intraocular pressure (IOP) was significantly lower in the aMCI patients. A significant decrease in RNFL thickness in superior temporal, temporal upper (TU), and temporal upper and lower (TL) (TU+TL) quadrants was found in the aMCI patients than in the controls. The average thickness of the mGCC was also significantly thinner in the aMCI patients than in the controls. CONCLUSIONS: Retinal degeneration in the aMCI patients detected by OCT together with lower IOP may indicate disease pathological progression. PMID- 29447482 TI - Role of vitamin A supplementation in prevention of bronchopulmonary dysplasia in extremely low birth weight neonates: a systematic review of randomized trials. AB - BACKGROUND: Bronchopulmonary dysplasia (BPD) is one of the most common consequence of extreme prematurity (<28 weeks of gestation). BPD affects approximately 55% of extremely low birth weight (ELBW) neonates. AIMS: The aim of this systematic review is to evaluate the role of vitamin A supplementation in prevention of BPD in ELBW neonates. METHOD: The literature search was done for various randomized control trial (RCT) by searching the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, EMBASE, and ongoing clinical trials. RESULTS: This review included two RCTs that fulfilled inclusion criteria. There were statistically significant reduction in the incidence of BPD (oxygen requirement at 36 weeks of postmenstrual age (PMA)) (relative risk (RR) 0.88; 95%CI 0.77-0.99; p = .04; NNTB 14) and borderline significant reduction in combined outcomes of mortality/BPD (oxygen requirement at 36 weeks of PMA) (RR 0.90; 95%CI 0.82-1.00; p = .05). However, oxygen requirement at 28 days of life and combined outcome of mortality/BPD (oxygen requirement at 28 days of life) were not statistically significant. CONCLUSIONS: The role of vitamin A supplementation in the prevention of BPD is supported by the current evidences. However, due to limited number of studies, current evidences are not sufficient which can translate into routine clinical practice. We need large high-quality trials, with sufficient power to reliably assess clinically relevant differences in outcomes. PMID- 29447483 TI - The art of recovery: outcomes from participatory arts activities for people using mental health services. AB - BACKGROUND: There is a growing evidence base for the use of participatory arts for the purposes of health promotion. In recent years, recovery approaches in mental healthcare have become commonplace in English speaking countries amongst others. There are few studies that bring together these two fields of practice. AIMS: The two aims of this study were (a) to investigate the validity of the CHIME framework for characterising the experience of Participatory Arts and (b) to use the CHIME framework to investigate the relationship between participatory arts and mental health recovery. METHOD: The study employed a two-phase methodology: a rapid review of relevant literature followed by secondary analysis of qualitative data collected from 38 people who use mental health service who took part in participatory arts activities designed to improve mental health. RESULTS: Each of the recovery processes identified by CHIME are present in the qualitative research literature as well as in the data of the secondary analysis. CONCLUSIONS: Participatory arts activities produce outcomes which support recovery, specifically including enhancing connectedness and improving hope. They can be recommended to people living with mental health problems. PMID- 29447484 TI - Cationic DDA/TDB liposome as a mucosal vaccine adjuvant for uptake by dendritic cells in vitro induces potent humoural immunity. AB - The cationic dimethyldioctadecylammonium/trehalose 6,6,9-dibehenate (DDA/TDB) liposome is as a strong adjuvant system for vaccines, with remarkable immunostimulatory activity. The mucosal administration of vaccines is a potential strategy for inducing earlier and stronger mucosal immune responses to infectious diseases. In this study, we assessed whether the intranasal administration of cationic DDA/TDB liposomes combined with influenza antigen A (H3N2) can be used as a highly efficacious vaccine to induce mucosal and systemic antibody responses. Confocal laser scanning microscopy and a flow-cytometric analysis showed that the uptake of the cationic DDA/TDB liposome carrier was significantly higher than that of neutral 1,2-distearoyl-sn-glycero-3 phosphocholine/cholesterol (DSPC/Chol) or cationic 1,2-dioleoyl-3 trimethylammonium-propane/3beta-(N-[N',N'-dimethylaminoethane]-carbamoyl (DOTAP/DC-Chol) liposomes. Our results indicate that the cationic DDA/TDB liposome is more effective in facilitating its uptake by dendritic cells (DCs) in vitro than the DSPC/Chol or DOTAP/DC-Chol liposome. DCs treated with DDA/TDB liposomes strongly expressed CD80, CD86, and MHC II molecules, whereas those treated with DSPC/Chol or DOTAP/DC-Chol liposomes did not. C57BL/6 mice intranasally immunized with H3N2-encapsulating cationic DDA/TDB liposomes had significantly higher H3N2-specific s-IgA levels in their nasal wash fluid than those treated with other formulations. The DDA/TDB liposomes also simultaneously enhanced the serum IgG IgG2a, IgG1, and IgG2b antibody responses. In summary, DDA/TDB liposomes effectively facilitated their uptake by DCs and DCs maturation in vitro, and induced significantly higher mucosal IgA, systemic IgG, IgG1, and IgG2b antibody titres than other formulations after their intranasal administration in vivo. These results indicate that DDA/TDB liposomes are a promising antigen delivery carrier for clinical antiviral applications. PMID- 29447485 TI - Should women be screened for osteoporosis at midlife? AB - Osteoporosis and associated fractures are common in women after midlife and will increase as the population ages. Osteoporosis-related fractures cause a significant increase in morbidity and mortality. Osteoporosis decreases the quality of life and productivity of many older women, with an increasing burden on health-care resources. Future risk of fracture can be managed by evidence based interventions. It is thus appropriate to estimate the future risk of fracture in all women at the age of 50 years or at menopause, whichever occurs first. This can be achieved in a non-invasive fashion by targeted clinical history-taking. The future risk of fracture can be quantified using computerized models that integrate all risk factors, with or without dual-energy X-ray absorptiometry (DXA). Individuals found to be at increased risk of fracture need also to be assessed by DXA and, in the absence of lateral vertebral assessment, also by conventional X-ray imaging. All women should be screened by DXA at the age of 65 years, if not done before that time. At the age of 50, all women should be informed about a bone-friendly lifestyle. PMID- 29447486 TI - The Development of Mid-Wavelength Photoresponsivity in the Mouse Retina. AB - PURPOSE: Photoreceptors in the mouse retina express much of the molecular machinery necessary for phototransduction and glutamatergic transmission prior to eye opening at postnatal day 13 (P13). Light responses have been observed collectively from rod and cone photoreceptors via electroretinogram recordings as early as P13 in mouse, and the responses are known to become more robust with maturation, reaching a mature state by P30. Photocurrents from single rod outer segments have been recorded at P12, but no earlier, and similar studies on cone photoreceptors have been done, but only in the adult mouse retina. In this study, we wanted to document the earliest time point in which outer retinal photoreceptors in the mouse retina begin to respond to mid-wavelength light. METHODS: Ex-vivo electroretinogram recordings were made from isolated mouse retinae at P7, P8, P9, P10, and P30 at seven different flash energies (561 nm). The a-wave was pharmacologically isolated and measured at each developmental time point across all flash energies. RESULTS: Outer-retinal photoreceptors generated a detectable response to mid-wavelength light as early as P8, but only at photopic flash energies. a-wave intensity response curves and kinetic response properties are similar to the mature retina as early as P10. CONCLUSION: These data represent the earliest recorded outer retinal light responses in the rodent. Photoreceptors are electrically functional and photoresponsive prior to eye opening, and much earlier than previously thought. Prior to eye opening, critical developmental processes occur that have been thought to be independent of outer retinal photic modulation. However, these data suggest light acting through outer retinal photoreceptors has the potential to shape these critical developmental processes. PMID- 29447487 TI - Perianal Crohn's disease - association with significant inflammatory activity in proximal small bowel segments. AB - OBJECTIVES: Perianal Crohn's disease (CD) prevalence varies according to the disease location, being particularly frequent in patients with colonic involvement. We aimed to evaluate small bowel involvement and compare small bowel capsule endoscopy findings and inflammatory activity between patients with and without perianal disease. MATERIALS AND METHODS: Retrospective single-center study including 71 patients - all patients with perianal CD (17 patients) who performed a small bowel capsule endoscopy were included, and non-perianal CD patients were randomly selected (54 patients). Clinical and analytical variables at diagnosis were reviewed. Statistical analysis was performed with SPSS v21.0 and a two-tailed p value <.05 was defined as indicating statistical significance. RESULTS: Patients had a median age of 30 +/- 16 years with 52.1% females. Perianal disease was present in 23.9%. Patients with perianal disease had significantly more relevant findings (94.1% vs 66.6%, p = .03) and erosions (70.6% vs 42.6%, p = .04), however, no differences were found between the two groups regarding ulcer, villous edema and stenosis detection. Overall, patients with perianal disease had more frequently significant small bowel inflammatory activity, defined as a Lewis Score >=135 (94.1% vs 64.8%, p = .03), and higher Lewis scores in the first and second tertiles (450 +/- 1129 vs 0 +/- 169, p = .02 and 675 +/- 1941 vs 0 +/- 478, p = .04, respectively). No differences were found between the two groups regarding third tertile inflammatory activity assessed with the Lewis Score. CONCLUSION: Patients with perianal CD have significantly higher inflammatory activity in the small bowel, particularly in proximal small bowel segments, when compared with patients without perianal disease. PMID- 29447488 TI - Long-term effects of Lee Silverman Voice Treatment on daily voice use in Parkinson's disease as measured with a portable voice accumulator. AB - This study examines the effects of an intensive voice treatment focusing on increasing voice intensity, LSVT LOUD(r) Lee Silverman Voice Treatment, on voice use in daily life in a participant with Parkinson's disease, using a portable voice accumulator, the VoxLog. A secondary aim was to compare voice use between the participant and a matched healthy control. Participants were an individual with Parkinson's disease and his healthy monozygotic twin. Voice use was registered with the VoxLog during 9 weeks for the individual with Parkinson's disease and 2 weeks for the control. This included baseline registrations for both participants, 4 weeks during LSVT LOUD for the individual with Parkinson's disease and 1 week after treatment for both participants. For the participant with Parkinson's disease, follow-up registrations at 3, 6, and 12 months post treatment were made. The individual with Parkinson's disease increased voice intensity during registrations in daily life with 4.1 dB post-treatment and 1.4 dB at 1-year follow-up compared to before treatment. When monitored during laboratory recordings an increase of 5.6 dB was seen post-treatment and 3.8 dB at 1-year follow-up. Changes in voice intensity were interpreted as a treatment effect as no significant correlations between changes in voice intensity and background noise were found for the individual with Parkinson's disease. The increase in voice intensity in a laboratory setting was comparable to findings previously reported following LSVT LOUD. The increase registered using ambulatory monitoring in daily life was lower but still reflecting a clinically relevant change. PMID- 29447489 TI - Compulsory Use of the Backboard is Associated with Increased Frequency of Thoracolumbar Imaging. AB - BACKGROUND: Backboards have been shown to cause pain in uninjured patients. This may alter physical exam findings, leading emergency department (ED) providers to suspect a spinal injury when none exists resulting in additional imaging of the thoracolumbar spine. New York had previously employed a "Spinal Immobilization" protocol that included compulsory backboard application for all patients with suspected spinal injuries. In 2015, New York instituted a new "Spinal Motion Restriction" protocol that made backboard use optional for these patients. The objective of this study was to determine if this protocol change was associated with decreased backboard utilization and ED thoracolumbar spine imaging. METHODS: This was a retrospective before-and-after chart review of subjects transported by a single emergency medical services (EMS) agency to one of four EDs for emergency calls dispatched as motor vehicle collisions (MVC). EMS and ED data were included for all calls within a 6-month interval before and after the protocol change. The protocol change was implemented in the second half of 2015. Subject demographics, backboard use, and spine imaging were reviewed for the intervals January-June 2015 and January-June 2016. RESULTS: There were 818 subjects in the before period and 796 subjects in the after period. Subjects were similar in terms of gender, age and type of MVC in both periods. A backboard was utilized for 440 (54%) subjects in the before period and 92 (12%) subjects in the after period (p < 0.001). ED thoracic spine imaging was performed on 285 (35%) subjects in the before period, and 235 (30%) subjects in the after period (p = 0.02). ED lumbar spine imaging was performed for 335 (41%) subjects in the before period, and 281 (35%) subjects in the after period (p = 0.02). CONCLUSION: A shift from a spinal immobilization protocol to a spinal motion restriction protocol was associated with a decrease in backboard utilization by EMS providers and a decrease in thoracolumbar spine imaging by ED providers. PMID- 29447490 TI - Combined effects of artificial dermis and vascular endothelial growth factor concentration gradient on wound healing in diabetic porcine model. AB - Wounds in patients with diabetes mellitus are one of the most prevalent impaired wounds in the world. Vascular endothelial growth factor (VEGF) is one of the most important proangiogenic mediators. Artificial dermal (AD) such as Pelnac(r) has been shown, in humans and animal models, a great therapeutic potential in full thickness skin wounds. We attempt to promote the wound healing in diabetic porcine models through combined use of AD and constant concentration of VEGF or VEGF concentration gradient. We created full-thickness excisional wounds in diabetic animal models. Analyzed the healing process through images, histology and immunohistochemistry. Results show that the combination of AD and concentration gradient of VEGF could provide an appropriate angiogenesis, improve granulation formation, increase epithelization and maintain the VEGF levels of the wound bed. Eventually accelerate the direct healing of diabetic wounds or make good preparation for secondary skin graft. PMID- 29447491 TI - Association between Th1/Th2 immune imbalance and obesity in women with or without polycystic ovary syndrome. AB - OBJECTIVES: This study aimed to investigate the Th1/Th2 cells in peripheral blood of PCOS patients, and assess the potential correlation between Th1/Th2 imbalance and obesity. METHODS: Thirty-nine PCOS patients and 23 age-matched controls were enrolled. The PBMCs were obtained before pharmacological intervention in women with or without PCOS. The profiles of Th1 (IFN-gamma) and Th2 (IL-4) cytokines of CD3+CD- T lymphocyte subsets were analyzed by flow cytometry. Plasma sex hormones including E2, T, FSH, LH, and FINS, FPG were measured, together with BMI, WC, LH/FSH, E2/T and HOMA-IR index being calculated. Association between Th1/Th2 imbalance and BMI, WC were evaluated. RESULTS: The proportion of Th1 cells and Th1/Th2 ratio were significantly higher in PCOS patients than those in controls, accompanied by elevated T, LH, LH/FSH, FINS, HOMA-IR index and reduced E2/T. The Th1/Th2 ratio was increased when BMI and WC were enhanced in PCOS. Moreover, the significant difference of Th1/Th2 ratio was observed between WC subgroups of PCOS. CONCLUSIONS: It is concluded that Th1 type immunity is predominant in systemic immunization of PCOS patients. Th1/Th2 immune imbalance is connected with obesity, especially abdominal obesity, and may be one of the underlying mechanism for the pathogenesis of PCOS.

AB - OBJECTIVES: To explore strategies used by physiotherapists (PTs) in guiding people with rheumatoid arthritis to health-enhancing physical activity (HEPA) in a group setting during a 1-year intervention study. METHODS: Exploratory design with qualitative video analysis performed in three steps. Eleven female PTs were video recorded while leading support group sessions aiming at facilitating HEPA (twice-weekly exercise sessions at public gyms and 150 weekly minutes of moderately intense aerobic physical activity). RESULTS: Three categories of challenging situations emerged. They occurred when the HEPA intervention participants reported barriers to performing physical activity, when they neglected to use the planning tool for physical activity as intended in the program, and when they received negative results from physical capacity tests. PTs used different strategies to manage these challenges, with main focus either on information-giving, corresponding to a traditional health professional approach, or utilizing group resources by organizing participation. CONCLUSIONS: This study provides detailed descriptions of PTs' clinical behavior in video recorded sessions. The results imply that motivated PTs can, despite their biomedical and practitioner-focused training, learn to adapt their communication strategies to different situations, altering between traditional information giving and utilizing group resources by organizing participation.

AB - AIM: Despite the high prevalence of chronic neck pain, there is limited consensus about the primary etiology, risk factors, diagnostic criteria and therapeutic outcome. Here, we aimed to determine if Ferritin and Vitamin D are modifiable risk factors with chronic neck pain using slandered statistics and artificial intelligence neural network (ANN). METHODS: Fifty-four patients with chronic neck pain treated between February 2016 and August 2016 in King Abdullah University Hospital and 54 patients age matched controls undergoing outpatient or minor procedures were enrolled. Patients and control demographic parameters, height, weight and single measurement of serum vitamin D, Vitamin B12, ferritin, calcium, phosphorus, zinc were obtained. An ANN prediction model was developed. RESULTS: The statistical analysis reveals that patients with chronic neck pain have significantly lower serum Vitamin D and Ferritin (p-value <.05). 90% of patients with chronic neck pain were females. Multilayer Feed Forward Neural Network with Back Propagation(MFFNN) prediction model were developed and designed based on vitamin D and ferritin as input variables and CNP as output. The ANN model output results show that, 92 out of 108 samples were correctly classified with 85% classification accuracy. CONCLUSIONS: Although Iron and vitamin D deficiency cannot be isolated as the sole risk factors of chronic neck pain, they should be considered as two modifiable risk. The high prevalence of chronic neck pain, hypovitaminosis D and low ferritin amongst women is of concern. Bioinformatics predictions with artificial neural network can be of future benefit in classification and prediction models for chronic neck pain. We hope this initial work will encourage a future larger cohort study addressing vitamin D and iron correction as modifiable factors and the application of artificial intelligence models in clinical practice.

AB - Vitamin D has a crucial role in female reproduction, possibly through its effects on calcium homeostasis, cyclic sex steroid hormone fluctuations, or neurotransmitter function. We have assessed the effects of vitamin D supplementation on dysmenorrhea and premenstrual syndrome (PMS) in adolescents. In this study, 897 adolescent girls living in Mashhad and Sabzevar, Iran, received nine high-dose vitamin D supplements (as 50,000 IU/week of cholecalciferol) and were followed up over 9 weeks. We evaluated the effect of vitamin D supplementation on individuals in four categories: those with only PMS; individuals with only dysmenorrhea; subjects with both PMS and dysmenorrhea and normal subjects. The prevalence of PMS after the intervention fell from 14.9% to 4.8% (p < .001). Similar results were also found for the prevalence of subjects with dysmenorrhea (35.9% reduced to 32.4%), and in subjects with both PMS and dysmenorrhea (32.7% reduced 25.7%). Vitamin D supplementation was associated with a reduction in the incidence of several symptoms of PMS such as backache and tendency to cry easily as well as decrement in pain severity of dysmenorrhea (p < .05). High dose vitamin D supplementation can reduce the prevalence of PMS and dysmenorrhea as well as has positive effects on the physical and psychological symptoms of PMS.

AB - Estrogen receptor alpha (ERalpha) and retinoic acid receptors (RARs) play important and opposite roles in breast cancer growth. While exposure to ERalpha agonists such as 17beta-estradiol (E2) is related to proliferation, RAR agonists such as all-trans retinoic acid (AtRA) induce anti-proliferative effects. Although crosstalk between these pathways has been proposed, the molecular mechanisms underlying this interplay are still not completely unraveled. The aim of this study was to evaluate the effects of AtRA on ERalpha-mediated signaling in the ERalpha positive cell lines MCF7/BUS and U2OS-ERalpha-Luc to investigate some of the possible underlying modes of action. To do so, this study assessed the effects of AtRA on different ERalpha-related events such as ERalpha-mediated cell proliferation and gene expression, ERalpha-coregulator binding and ERalpha subcellular localization. AtRA-mediated antagonism of E2-induced signaling was observed in the proliferation and gene expression studies. However, AtRA showed no remarkable effects on the E2-driven coregulator binding and subcellular distribution of ERalpha. Interestingly, in the absence of E2, ERalpha-mediated gene expression, ERalpha-coregulator binding and ERalpha subcellular mobilization were increased upon exposure to micromolar concentrations of AtRA found to inhibit cell proliferation after long-term exposure. Nevertheless, experiments using purified ERalpha showed that direct binding of AtRA to ERalpha does not occur. Altogether, our results using MCF7/BUS and U2OS-ERalpha-Luc cells suggest that AtRA, without being a direct ligand of ERalpha, can indirectly interfere on basal ERalpha-coregulator binding and basal ERalpha subcellular localization in addition to the previously described crosstalk mechanisms such as competition of ERs and RARs for DNA binding sites.

AB - BACKGROUND: The research of G protein-coupled receptors (GPCRs) is a promising strategy for drug discovery. In cancer therapy, there is a need to discover novel agents that can inhibit proliferation and induce apoptosis in cancer cells. JTC 801 is a novel GPCR antagonist with the function of reversing pain and anxiety symptoms. This study aims to investigate the antitumor effects of JTC-801 on human osteosarcoma cells (U2OS) and elucidate the underlying mechanism. MATERIALS AND METHODS: The Cell Counting Kit-8 assay was used to detect the viability of U2OS cells treated with JTC-801 in vitro. The cell apoptosis was evaluated using a flow cytometry assay with Annexin V-FITC/PI double staining. The inhibitory effect of JTC-801 on invasion and migration of U2OS cells were determined by the Transwell assays. Western blot assay was performed to measure the levels of proteins related to cell apoptosis and its mechanism. RESULTS: The JTC-801 significantly decreased the viability of U2OS cells (p < .05) as a result of its anti-proliferative effect through induction of apoptosis associated with activation of BAX, Caspase-3 and down-regulating BCL-2 expression. The invasive and migratory cells were obviously reduced after JTC-801 treatment (p < .05). Further, the phosphorylated AKT, mTOR and active p70 S6 protein kinase in the PI3K/AKT signaling pathway were obviously lessened in the JTC-801 treated U2OS group (p < .05). CONCLUSIONS: JTC-801 may exert osteosarcoma cell growth inhibition by promoting cell apoptosis, through PI3K/AKT signaling pathway participation.

AB - INTRODUCTION: The purpose of this study was to examine the relationship of sleep quality to proneness to hallucinations and the mediating role of dissociation and unusual sleep experiences in a nonclinical sample. METHODS: One hundred and seventy-seven participants completed a questionnaire on sleep quality, a dissociative experiences scale, an unusual sleep experiences scale and a hallucination proneness scale. RESULTS: The results showed a significant positive association between quality of sleep and hallucination proneness, dissociation and unusual sleep experiences, and that dissociation and unusual sleep experiences fully mediated between sleep quality and hallucination proneness. CONCLUSIONS: Our study highlights the importance of variables related to sleep quality and unusual sleep experiences and dissociation in understanding hallucinations, and the importance of taking these variables into consideration in designing intervention directed at reducing distress caused by hallucinations. PMID- 29447542 TI - Predictors for orthopaedic surgery in patients with rheumatoid arthritis: results from a retrospective cohort study of 1010 patients diagnosed from 1972 to 2009 and followed up until 2015. AB - OBJECTIVES: To investigate how patient characteristics, time of diagnosis, and treatment affect the need for orthopaedic surgery in patients with rheumatoid arthritis (RA). METHOD: We reviewed the medical history of 1544 patients diagnosed with RA at Haukeland University Hospital in Bergen, Norway, from 1972 to 2009, of whom 1010 (mean age 57 years, 69% women) were included in the present study. Relevant orthopaedic procedures were obtained from the Norwegian Arthoplasty Register and the hospital's administrative patient records. In total, 693 procedures (joint synovectomies 22%, arthrodeses 21%, prostheses 41%, and forefoot procedures 12%) were performed in 315 patients. Survival analyses were completed to evaluate the impact of different factors such as age, gender, radiographic changes, and year of diagnosis, on the risk of undergoing surgery. RESULTS: Patients diagnosed in 1972-1985 and 1986-1998 had a relative risk of undergoing surgery of 2.4 and 2.2 (p < 0.001), respectively, compared to patients diagnosed in 1999-2009. Radiographic changes at diagnosis and female gender were also significant risk factors. Anti-rheumatic medication was significantly different in the three time periods. CONCLUSION: Patients with a diagnosis in the early years had a greatly increased risk of having orthopaedic surgery performed. This is probably due to the year of diagnosis being a proxy for the type and intensity of medical treatment. PMID- 29447544 TI - 'Asking' but Not 'Screening': Assessing Physicians' and Nurses' Substance-Related Clinical Behaviors. AB - BACKGROUND: Screening, brief intervention, and referral to treatment (SBIRT) is a promising public health approach for problematic substance use. A core component of SBIRT is the use of formal screening tools to categorize a patient's likely level of risk in order to provide an appropriately-matched service. Training in formal screening is included in many SBIRT training programs, but infrequently is emphasized. OBJECTIVES: To assess pre-training levels of SBIRT-related clinical behaviors, including screening, this study examined a secondary dataset collected from internal medicine residents and graduate nurse practitioner students. METHODS: Learners (n = 117) completed 13 self-report items assessing use of SBIRT related behaviors. Researchers used exploratory factor analysis to identify underlying concepts in the questionnaire, then used mixed ANOVA to compare mean frequency of utilization of each factor (asking, screening, and intervening) by academic program. RESULTS: Learners reported asking about substance use frequently, intervening some of the time, and infrequently using formal screening tools. Interaction and between-academic-program effects were significant but small. CONCLUSIONS: Prior to SBIRT training, most clinical practitioners reported asking patients about substance use, but few reported regularly using formal substance use screening tools. This may have implications for the importance of SBIRT training as part of curricular work, and for the internal content foci of SBIRT curricula.

AB - The purpose of this investigation was to assess the effect of compression sleeves on muscle activation cost during locomotion. Twenty-two recreationally active men (age: 25 +/- 3 years) ran on a treadmill at four different speeds (ordered sequence of 2.8, 3.3, 2.2, and 3.9 m/s). The tests were performed without (control situation, CON) and while wearing specially designed lower leg compression sleeves (SL). Myoelectric activity of five lower leg muscles (tibialis anterior, fibularis longus, lateral and medial head of gastrocnemius, and soleus) was captured using Surface EMG. To assess muscle activation cost, the cumulative muscle activity per distance travelled (CMAPD) of the CON and SL situations was determined. Repeated measures analyses of variance were performed separately for each muscle. The analyses revealed a reduced lower leg muscle activation cost with respect to test situation for SL for all muscles (p < 0.05, etap2 > 0.18). The respective significant reductions of CMAPD values during SL ranged between 4% and 16% and were largest at 2.8 m/s. The findings presented point towards an improved muscle activation cost while wearing lower leg compression sleeves during locomotion that have potential to postpone muscle fatigue.

AB - Older adults perceive less intense negative emotion in facial expressions compared to younger counterparts. Prior research has also demonstrated that mood alters facial emotion perception. Nevertheless, there is little evidence which evaluates the interactive effects of age and mood on emotion perception. This study investigated the effects of sad mood on younger and older adults' perception of emotional and neutral faces. Participants rated the intensity of stimuli while listening to sad music and in silence. Measures of mood were administered. Younger and older participants' rated sad faces as displaying stronger sadness when they experienced sad mood. While younger participants showed no influence of sad mood on happiness ratings of happy faces, older adults rated happy faces as conveying less happiness when they experienced sad mood. This study demonstrates how emotion perception can change when a controlled mood induction procedure is applied to alter mood in young and older participants.

AB - OBJECTIVE: The purpose of this viewpoint is to discuss the lack of research on resident advisor (RA) self-care and how behavioral interventions can be used in housing programs to educate and improve RA self-care. It is essential for live-in housing staff (both professional and paraprofessional) to learn how to develop appropriate strategies that target problem behaviors to improve self-care. An overview of the RA position, the effects of increased demands (i.e., burnout), and the research on self-care behavioral interventions are discussed. Lastly, the call to use behavioral interventions within housing programs to educate RAs on self-care awareness and improve and monitor their health behaviors to prevent burnout and psychological distress is provided.

PMID- 29447579 TI - Double gene targeting PCR assay for the detection of Crocodylus porosus in commercial products. AB - The demand for crocodile meat is quickly growing because of its exotic and organoleptic appeal and also the low content of cholesterol and lipids. Moreover, crocodile oil and blood have been used in alternative medicines for treating asthma and several other ailments since ancient times. Furthermore, crocodile hides have great demand in leather industries. All of these have collectively contributed to the extensive hunting, illegal trading and consequent decline of crocodiles in most parts of the world. To keep space with the growing demands, some crocodile species such as Crocodylus porosus have been raised in farms and its commercial trades have been legalised. However, demand for wild crocodiles in foods and medicines has continued in high gear. Recently, several DNA-based methods have been proposed for crocodile detection, but those assays are based on single gene and longer-sized amplicon targets that break down during extensive processing. To address this gap, here we developed and validated a highly stable double gene targeted multiplex PCR assay for the identification of C. porosus materials in commercial products. The assay involved two short sites from C. porosus atp6 (77 bp) and cytb (127 bp) genes and a universal internal control (99 bp) for eukaryotes. The PCR primers were cross-tested against 18 species and validated under pure and mixed matrices under extensive boiling, autoclaving and microwave cooking conditions. Finally, it was used to identify five crocodile based commercial products. The lower limits of detection for atp6 and cytb genes were 0.001 ng and 0.01 ng DNA, respectively, in pure meat and 1% under mixed matrices. Some inherent features, such as 77-127 bp amplicon sizes, exceptional stability and superior sensitivity, suggested the assay could be used for the identification of C. porosus in any forensic specimen. PMID- 29447580 TI - HPLC/PDA determination of carminic acid and 4-aminocarminic acid using relative molar sensitivities with respect to caffeine. AB - To accurately determine carminic acid (CA) and its derivative 4-aminocarminic acid (4-ACA), a novel, high-performance liquid chromatography with photodiode array detector (HPLC/PDA) method using relative molar sensitivity (RMS) was developed. The method requires no analytical standards of CA and 4-ACA; instead it uses the RMS values with respect to caffeine (CAF), which is used as an internal standard. An off-line combination of 1H-quantitative nuclear magnetic resonance spectroscopy (1H-qNMR) and HPLC/PDA was able to precisely determine the RMSs of CA274nm/CAF274nm and 4-ACA274nm/CAF274nm. To confirm the performance of the HPLC/PDA method using RMSs, the CA and 4-ACA contents in test samples were tested using four different HPLC-PDA instruments and one HPLC-UV. The relative standard deviations of the results obtained from five chromatographs and two columns were less than 2.7% for CA274nm/CAF274nm and 1.1% for 4 ACA274nm/CAF274nm. The 1H-qNMR method was directly employed to analyse the CA and 4-ACA contents in test samples. The differences between the quantitative values obtained from both methods were less than 5% for CA and 3% for 4-ACA. These results demonstrate that the HPLC/PDA method using RMSs to CAF is a simple and reliable quantification method that does not require CA and 4-ACA certified reference materials. PMID- 29447581 TI - Integrating Models of Diffusion and Behavior to Predict Innovation Adoption, Maintenance, and Social Diffusion. AB - This study documents an investigation into the adoption and diffusion of eave tubes, a novel mosquito vector control, during a large-scale scientific field trial in West Africa. The diffusion of innovations (DOI) and the integrated model of behavior (IMB) were integrated (i.e., innovation attributes with attitudes and social pressures with norms) to predict participants' (N = 329) diffusion intentions. The findings showed that positive attitudes about the innovation's attributes were a consistent positive predictor of diffusion intentions: adopting it, maintaining it, and talking with others about it. As expected by the DOI and the IMB, the social pressure created by a descriptive norm positively predicted intentions to adopt and maintain the innovation. Drawing upon sharing research, we argued that the descriptive norm may dampen future talk about the innovation, because it may no longer be seen as a novel, useful topic to discuss. As predicted, the results showed that as the descriptive norm increased, the intention to talk about the innovation decreased. These results provide broad support for integrating the DOI and the IMB to predict diffusion and for efforts to draw on other research to understand motivations for social diffusion.

PMID- 29447582 TI - Clinical characteristics and quality of life in Chinese patients with Parkinson's disease beyond 20 years. AB - Background The number of Parkinson's disease (PD) patients with disease duration of more than 20 years (long disease duration PD, LPD) is on the rise. Objectives This study aims to describe the clinical profiles and the quality of life (QoL) of LPD patients from a cohort of the Chinese population. Methods We compared 71 LPD subjects to 60 PD patients who died less than 20 years after the onset of PD (control PD, CPD). A regression model was constructed to assess the determinants for 20 years survival and the QoL of LPD patients. Results Compared to CPD patients, LPD patients exhibited a younger age at disease onset, higher total levodopa equivalent daily dose applications, more frequent motor complications, lower annual change in Unified PD Rating Scale (UPDRS) III score, as well as lower scores for 'sleep/fatigue' and 'mood/apathy' domains and higher score for 'sexual dysfunction' domain in the Non-Motor Symptom Scale (NMSS) (p < 0.05). Multivariate regression analyses indicated that a younger age at disease onset (OR = 0.520, 95%CI = 0.295-0.919, p = 0.024), lower annual change in UPDRS III score (OR = 0.009, 95%CI = 0.001-0.246, p = 0.005) and lower 'cardiovascular' score (OR = 0.552, 95%CI = 0.319-0.955, p = 0.034) were associated with 20-year survival, while UPDRS III (beta = 0.320, p < 0.001) and NMSS (beta = 0.549, p < 0.001) scores were associated with the PD Questionnaire 39 score in LPD. Conclusions The age at disease onset, rate of PD deterioration, and cardiovascular symptoms are the potential determinants for 20-year survival with PD. Both motor and non-motor disturbances contribute to the reduced QoL of LPD patients.

AB - : The aim of the study was to gain an in-depth understanding of opioid-dependent patients' lived experiences post-detoxification. METHOD: The study employed a naturalistic, observational longitudinal design, involving baseline screening and tracking of patients post-detoxification, with follow-up interviews at three, six, and nine months to observe specific processes of interest. This in-depth investigation of patients at four points was new within an Irish context and novel throughout the literature. FINDINGS: Recovery was seen as a process that was not always linear, and lapse and relapse were viewed as part of this process. Patients had great insight into "risk factors for relapse," information and knowledge gained over several years and many treatment episodes. Furthermore, the findings illustrate the role insight plays in any learning and growth experience and the emphasis that is placed upon it within the treatment journey; insight is a fundamental underpinning to any real growth and development. The current article argues that insight merits a more explicit role in the model of recovery capital. PMID- 29447585 TI - Service seeking experiences of college-aged sexual and intimate partner violence victims with a mental health and/or behavioral disability. AB - OBJECTIVE: To examine mental health service experiences following sexual violence (SV) and intimate partner violence (IPV) victimization among college women with a disability. PARTICIPANTS: College women (n = 27, ages 19 to 24) with a disability who experienced at least one SV/IPV occurrence; interviewed July/August 2016. METHODS: Qualitative study using in-depth interviews, with thematic analysis. RESULTS: Women tended to wait several months (or did not seek care at all) following SV/IPV, because they downplayed their experience (e.g., not wanting to label an experience as "rape"). Those seeking services primarily did so because of escalating mental health concerns. Among service seekers, women were satisfied when professionals validated their experiences/concerns; and were dissatisfied when faced with extended wait time for care and/or professionals unskilled with SV/IPV and mental health. However, women still sought care following negative experiences. CONCLUSIONS: Improved access to integrated care for SV/IPV and mental health, along with skilled professionals, is essential. PMID- 29447586 TI - A longitudinal study of interest and membership in a fraternity, rape myth acceptance, and proclivity to perpetrate sexual assault. AB - OBJECTIVE: This study explored the relation between interest and membership in a fraternity and acceptance of sexual violence (eg, rape myth acceptance, proclivity to perpetrate sexual aggression) among first year college men. PARTICIPANTS: A total of 315 men were surveyed before their first year of college (June-August 2010) and again at 4 time points over the next year. METHODS: Participants responded to measures of rape myth acceptance and proclivity to perpetrate sexual aggression. RESULTS: Interested members scored higher on proclivity to perpetrate sexual aggression and some rape myths than noninterested nonmembers; interested nonmembers scored in between the 2 groups. CONCLUSIONS: Results highlight the importance of considering both fraternity membership and interest in joining a fraternity, as well as examining individual rape myths, in studies of fraternity membership and sexual violence. PMID- 29447587 TI - A photochemically induced fluorescence based flow-through optosensor for screening of nitenpyram residues in cruciferous vegetables. AB - One of the most used agrochemicals in agricultural production, nitenpyram (NTP), has been determined by using a flow-through optosensing device based on Photochemically Induced Fluorescence detection. The combination of both methodologies allows, on one hand, a quick on-line photodegradation of NTP and, on the other hand, the preconcentration, quantification and desorption of the fluorescent photoproduct generated when retained on Sephadex QAE-A25 as solid support, which was monitored at 295 and 362 nm for excitation and emission, respectively. The proposed analytical method presents a detection limit of 500 pg mL-1 by using Multicommutated Flow Injection Analysis. Recovery experiments were carried out in different kinds of cruciferous vegetables at or below the MRL established in Japan, demonstrating that this method combines advantages of simplicity, high sensibility and high selectivity, fulfilling the requirements for its application in quality control. Results obtained in the analysis of real samples were in good agreement with those provided by a reference HPLC method. PMID- 29447588 TI - Psychotherapy Termination Practices with Older Adults: Impact of Patient and Therapist Characteristics. AB - OBJECTIVES: The aims of this study were to survey clinicians' opinions regarding psychotherapy practices in mutual termination with a specified population (depressed older adult outpatients) and to examine the patient and therapist characteristics that may influence such practices. METHODS: We surveyed psychologists' (N = 96) psychotherapy termination practices, using a hypothetical depressed older adult as a referent, to assess consensus on the appropriateness of various guidelines to termination and to examine whether these differ as a function of patient and therapist characteristics. RESULTS: Several practices were generally agreed to be "extremely appropriate" when terminating psychotherapy with older adults, including collaborating to determine the end date of treatment and discussing patient growth. Data also indicate that patient factors, such as personality pathology, and therapist factors, such as having an Integrative theoretical orientation were associated with differential endorsement of termination practices. Identification as a geropsychologist or working regularly with older adults were associated with a more cautious approach to termination. CONCLUSIONS: There is substantial consensus regarding many approaches to termination, but modifications might be appropriate depending on patient characteristics. CLINICAL IMPLICATIONS: Clinicians agree on a set of fundamental termination practices when working with older adults, but modify these based on orientation and diagnosis. PMID- 29447589 TI - Do student service members/veterans experience worse mental health stigma than their peers? A comparative study in a national sample. AB - OBJECTIVES: Examine differences in mental health treatment-related stigma in student service members and veterans (SSM/Vs) and peers from 57 post-secondary institutions across the United States. METHODS: In total, 909 SSM/Vs and 1818 demographically- and institutionally-matched non-SSM/Vs completed assessments of stigma-related barriers to mental health service utilization as part of the Healthy Minds Study between 2011 and 2015. RESULTS: When compared to non-SSM/V peers, SSM/Vs reported more mental health treatment-related stigma toward help seekers and less confidence in the helpfulness of therapy/counseling and psychotropic medications. However, effect sizes were small in magnitude (ds = .10 to .16), and depressed students in both groups reported greater stigma. CONCLUSIONS: SSM/Vs experience greater treatment-related stigma than non-SSM/V peers, which may deter service use in many cases. However, differences in stigma were small and other under-studied barriers to help-seeking may apply to the substantive subset of SSM/Vs and non-SSM/Vs who may benefit from utilizing available services. PMID- 29447590 TI - Correction to: Li, X., Li, W., Shi, Mo, Luo, Qin, Yang and Mo, Is serum bilirubin associated with the severity of Guillain-Barre syndrome? PMID- 29447591 TI - Characterization of a partial-body irradiation model with oral cavity shielding in nonhuman primates. AB - PURPOSE: Characterization of a novel partial-body irradiation (PBI) shielding strategy in nonhuman primates (NHP; rhesus macaques), aimed at protecting the oral cavity, with respect to various gastrointestinal acute radiation syndrome (GI-ARS) syndrome parameters as well as buccal ulceration development. MATERIALS AND METHODS: NHPs were irradiated using a Cobalt-60 gamma source, in a single uniform dose, ranging from 9-13 Gy and delivered at 0.60-0.80 Gy min-1. Animals were either partially shielded via oral cavity shielding (PBIOS) or underwent total-body irradiation (TBI). RESULTS: Clinical manifestations of GI-ARS, and also radiation-induced hematology and clinical chemistry changes, following PBIOS were comparable to the PBI NHP GI-ARS model utilizing shielding of the distal pelvic limbs and were significantly milder than TBI at similar radiation doses. Nadir citrulline levels were comparable between PBIOS and TBI but signs of recovery appeared earlier in PBIOS-treated animals. The PBIOS model prevented oral mucositis, whereas the TBI model presented buccal ulcerations at all tested radiation dose levels. CONCLUSIONS: Taken together, these results suggest that the PBIOS model is a suitable alternative to traditional PBI. For GI-ARS investigations requiring orally administered medical countermeasures, PBIOS confers added value due to the prevention of oral mucositis over traditional PBI. PMID- 29447600 TI - Does self-help increase rates of help seeking for student mental health problems by minimizing stigma as a barrier? AB - OBJECTIVE: This study examined whether self-help (books, websites, mobile apps) increases help seeking for mental health problems among college students by minimizing stigma as a barrier. PARTICIPANTS AND METHODS: A survey was conducted with 200 college students reporting elevated distress from February to April 2017. RESULTS: Intentions to use self-help were low, but a significant portion of students unwilling to see mental health professionals intended to use self-help. Greater self-stigma related to lower intentions to seek professional help, but was unrelated to seeking self-help. Similarly, students who only used self-help in the past reported higher self-stigma than those who sought professional treatment in the past. Although stigma was not a barrier for self-help, alternate barriers were identified. CONCLUSIONS: Offering self-help may increase rates of students receiving help for mental health problems, possibly by offering an alternative for students unwilling to seek in-person therapy due to stigma concerns. PMID- 29447601 TI - Examining the influence of gender and sexual motivation in college hookups. AB - OBJECTIVE: Hooking up is common in college, and has been linked to heavy drinking. Hookups have positive as well as negative consequences, and thus the motivations for hooking up are complex. Yet, little research has focused on these motivations. The present study examined the role that gender and drinking patterns play in the relationship between sexual motivation and penetrative hookups. PARTICIPANTS: Heavy drinking college students (N = 396) completed online surveys between September/October 2009. METHOD: Sexual motivation, alcohol, and hooking up were assessed. RESULTS: Enhancement motives and drinking frequency predicted more frequent oral and vaginal sex when hooking up, while peer and partner motives predicted anal sex. Men endorsed greater enhancement motives, peer motives, and hookup oral and vaginal sex. For men, coping motives predicted oral and vaginal sex and peer motives predicted anal sex. CONCLUSIONS: Results provide greater insight into the reasons why college students engage in penetrative hookups. PMID- 29447612 TI - Urban college student self-report of hookah use with health care providers. AB - OBJECTIVE: This study's purpose was to describe urban college students' communication about hookah with health care providers. PARTICIPANTS: Participants included a random sample of undergraduate urban college students and health care providers. METHODS: Students surveyed determined the epidemiology of hookah use in this population, how many health care providers asked about hookah, and how many students admitted hookah use to a physician. RESULTS: Of 375 students surveyed, 78 (20.8%) had never tried it, 284 (75.7%) had smoked hookah at least once, and 64 students (22.6%) were classified as frequent hookah smokers. Only 15 (4.7%) reported a health care provider asking about hookah during visits, whereas 36 (12.7%) admitted their hookah use to a health care provider. CONCLUSION: Hookah use was found to be highly prevalent among students in one urban university. This study supports the hypothesis that few health care providers broach the topic with patients. Additional research on health consequences of hookah use, education, and improved screening is warranted. PMID- 29447613 TI - "Who'll do all these if I'm not around?": Bonding social capital and health and well-being of inpatients. AB - PURPOSE: Although social capital influences health-related decisions and behavioural patterns in many developing countries, minimal attention has been paid to the nuances of its effect on healthcare. This paper examines how bonding social capital affects healthcare delivery for inpatients in Ghana. METHODS: Semi structured in-depth interviews were used and thematic analysis method employed to analyse the data. Interviews were conducted with health professionals and relatives and close friends of inpatients in three public health facilities in Ashanti region. RESULTS: Relatives and close friends of inpatients were a critical source of instrumental support such as provision of meals, laundry services, running errands and financial assistance as well as emotional support. These functions-that were both 'expected' and 'encouraged'- reduced the burden on the health facilities, which apparently had limited resources to offer adequate care. However, the relatives of inpatients sometimes inadvertently obstructed efficient healthcare delivery through actions such as extending 'unapproved' alternative care to patients. Moreover, the process of contributing towards health and well-being of the sick exposed the relatives to health risks due to poor living conditions. CONCLUSION: A well-defined and befitting role must be devised for at least an immediate social relation of inpatients to improve the positive effects of bonding social capital on healthcare delivery. PMID- 29447615 TI - Insights into structural features of HDAC1 and its selectivity inhibition elucidated by Molecular dynamic simulation and Molecular Docking. AB - Histone deacetylases (HDACs) are a family of proteins whose main function is the removal of acetyl groups from lysine residues located on histone and non-histone substrates, which regulates gene transcription and other activities in cells. HDAC1 dysfunction has been implicated in cancer development and progression; thus, its inhibition has emerged as a new therapeutic strategy. Two additional metal binding sites (Site 1 and Site 2) in HDACs have been described that are primarily occupied by potassium ions, suggesting a possible structural role that affects HDAC activity. In this work, we explored the structural role of potassium ions in Site 1 and Site 2 and how they affect the interactions of compounds with high affinities for HDAC1 (AC1OCG0B, Chlamydocin, Dacinostat and Quisinostat) and SAHA (a pan-inhibitor) using molecular docking and molecular dynamics (MD) simulations in concert with a Molecular-Mechanics-Generalized-Born-Surface-Area (MMGBSA) approach. Four models were generated: one with a potassium ion (K+) in both sites (HDAC1k), a second with K+ only at site 1 (HDAC1ks1), a third with K+ only at site 2 (HDAC1ks2) and a fourth with no K+ (HDAC1wk). We found that the presence or absence of K+ not only impacted the structural flexibility of HDAC1, but also its molecular recognition, consistent with experimental findings. These results could therefore be useful for further structure-based drug design studies addressing new HDAC1 inhibitors. PMID- 29447616 TI - Predictors of positive development in first-year college students. AB - OBJECTIVE: Emerging adulthood is an important phase in the transition to adulthood. Emerging adults experience minimal social control and incomplete development of executive functioning leaving this age-group at risk for misusing this newfound independence. Hence, it is important to understand pathways to support positive development (PD) outcomes. In this study, we examined the relationship between participation in civically engaged learning and PD among first-year college students. PARTICIPANTS: First-year college students (N = 225) were surveyed during the 2012-2013 academic year. METHODS: Students were surveyed on measures of PD and engaged learning prior to the beginning (initial survey) and at the end of the first year (final survey) of their undergraduate education. Stepwise linear regression was used to examine the influence of engaged learning on PD outcomes. RESULTS: Engaged learning during the academic year predicted flourishing and students' civic frequency. Also, faith-affiliation and parents' civic frequency contributed to students' civic frequency. CONCLUSIONS: Our interpretation of the findings suggests that engaged learning and family role modeling may promote PD among first-year undergraduate students. PMID- 29447614 TI - Adherence and perceived barriers to oral antiviral therapy for chronic hepatitis B. AB - BACKGROUND: Globally, of the 248 million people chronically infected with the hepatitis B virus (HBV), 74 million reside in China. Five oral nucleot(s)ide analogs (NUCs) have been approved for the treatment of chronic hepatitis B (CHB) in China. OBJECTIVES: The aims of this study were to determine rates of adherence to NUC therapy in patients with CHB, to identify the self-perceived barriers to adherence, and to examine the factors associated with adherence. METHODS: Questionnaire-based interviews were administered among Chinese patients with CHB at hepatology clinics of a tertiary hospital in the city of Wuhan, China. Adults aged 18 years or older prescribed with NUCs were recruited and interviewed to complete a 27-item questionnaire in a private setting, and adherence was measured using the Morisky Medication Adherence Scale (MMAS-8). RESULTS: Among 369 participants, only 16.5% had high adherence (score of 8), 32.2% had medium adherence (score of 6 to <8), and 51.2% were measured with low adherence (score of <6). A logistic regression model was used to determine the factors associated with medication adherence. Significant predictors of high adherence consisted of urban residency, non-cirrhotic status, not using prescribed pills other than HBV medications, and reminders from family members. The five most common reasons for skipping NUCs were that medication(s) are expensive (48.7%), forgetfulness (45.1%), have experienced or worry about potential side effects (19.8%), do not want others to know about my medication(s) usage (18.5%), and ran out of pills and do not have time to refill (15.9%). CONCLUSIONS: This study revealed that adherence rates to oral antiviral therapy were far from optimal. This finding should generate public attention, and it would be beneficial for interventional programs to target Chinese patients from rural regions, as well as patients with low socioeconomic status, cirrhosis, and taking multiple medications. PMID- 29447617 TI - Experience with Event Timing Does not Alter Emergent Timing: Further Evidence for Robustness of Event and Emergent Timing. AB - Although, event and emergent timings are thought of as mutually exclusive, significant correlations between tapping and circle drawing (Baer, Thibodeau, Gralnick, Li, & Penhune, 2013 ; Studenka, Zelaznik, & Balasubramaniam, 2012 ; Zelaznik & Rosenbaum, 2010 ) suggest that emergent timing may not be as robust as once thought. We aimed to test this hypothesis in both a younger (18-25) and older (55-100) population. Participants performed one block of circle drawing as a baseline, then six blocks of tapping, followed by circle drawing. We examined the use of event timing. Our hypothesis that acute experience with event timing would bias an individual to use event timing during an emergent task was not supported. We, instead, support the robustness of event and emergent timing as independent timing modes. PMID- 29447618 TI - Long-term impacts of college sexual assaults on women survivors' educational and career attainments. AB - OBJECTIVE: To examine the well-documented mental and physical health problems suffered by undergraduate women sexually assaulted while on campus with an exploration of how the trauma impacts a survivor's lifetime education trajectory and career attainment. PARTICIPANTS: In November and December 2015, researchers recruited US participants using an online crowdsourcing tool and a Listserv for sexual violence prevention and response professionals. METHODS: Of 316 women who completed initial screening, 89 qualified to complete a Qualtrics survey. Eighty one participants completed the online survey, and 32 participated in phone interviews. RESULTS: Ninety-one percent of the participants reported health problems related to the assault that they attributed to difficulties they faced in their attainment of their education and career goals. CONCLUSIONS: The findings suggest the importance of simultaneously examining the effects of human capital losses and mental and physical health problems attributed to the costly public health problem of campus sexual assault. PMID- 29447619 TI - Autism spectrum disorder traits in typically developing emerging adults and associated parenting: A person-centered approach. AB - Research on parenting children with autism spectrum disorder (ASD) indicates these children receive parenting tailored to their condition. However, little is known about ASD in adulthood, especially in emerging adults at college, and how they are parented. The current study examined how emerging adults in a non clinical typically-developing sample differed in their current perceptions of parenting as a function of ASD traits. Participants completed questionnaires about their current perceptions of parenting and self-reported ASD traits. Parenting characteristics assessed included parenting style, discipline, parent child relationship quality, and parental distress. Results indicated that higher levels of self-reported ASD traits were associated with increasingly ineffective parenting characteristics including lower authoritative style, harsher discipline, poorer parent-child relationship quality (e.g., lower involvement), and higher parental distress. Researchers are encouraged to extend ASD research into adulthood by validating diagnostic methods with adults and investigating processes in adulthood that have been well-established in the childhood ASD literature. PMID- 29447620 TI - Using smartphones to collect daily sexual behavior data from college students. AB - OBJECTIVE: Our objectives were to measure reporting differences between sexual behavior data from daily diary and retrospective estimates and to assess the utility of using smartphones to collect sexual behavior data from a college student population. PARTICIPANTS: Eighty-six participants (68 women, 18 men) completed the study. METHODS: For 30 days during the Spring 2017 semester, participants received prompts to participate in daily diaries about their previous day's sexual behavior on their smartphones. Participants then retrospectively reported their past 30 days of sexual behavior and provided feedback on the process of receiving daily diaries on their smartphones. RESULTS: We found that college students overreported their sexual behavior on the retrospective survey compared to their daily diary reports (ps < .001; Cohen's ds >= 1.51). Participants provided positive and constructive feedback. CONCLUSIONS: Using smartphones to administer daily diaries is a promising technique for obtaining reliable sexual behavior data from college students. PMID- 29447621 TI - College students' use of technology to communicate with romantic partners about sexual health issues. AB - OBJECTIVE: To examine college students' technology-assisted sexual communication perceptions and practices alongside their beliefs about the effectiveness of face to-face (F-t-F) sexual communication. PARTICIPANTS: 144 college students at a private university in the Northeast, U.S., completed a survey in October 2016. METHOD: A cross-sectional online survey examined how college students use text messaging and private social media messaging to communicate with romantic partners about sexual health issues. RESULTS: Students who have communicated with romantic partners via technology reported being likely to do so again in the future, to perceive the effectiveness of technology-assisted sexual communication to be comparable to F-t-F sexual communication, and to be confident in their ability to initiate sexual communication with romantic partners via F-t-F communication. CONCLUSIONS: College students may see text messaging and social media messaging as useful for sexual communication, which has important implications for college health professionals who wish to promote frequent, effective sexual communication. PMID- 29447622 TI - Online readiness assessment for Smoke- and Tobacco-free campus policies. AB - OBJECTIVE: Develop and test an online survey to assess campus readiness to adopt smoke- and tobacco-free (SF/TF) policies. PARTICIPANTS: Key informants (N = 18) at four campuses in Kentucky without a SF/TF policy recruited April 2015. METHODS: Cross-sectional design. The survey assessed six dimensions: knowledge about SF/TF policies; leadership for campus policy; resources for policy development; campus climate surrounding tobacco issues; existing tobacco policies; and political climate for campus policy development. Dimension raw scores were rescaled to range from 0-1 and summed to determine overall stage of readiness (0-6). RESULTS: Political climate was highest dimension across all campuses (0.83-1.0). Knowledge dimension ranked lowest (0.0-0.50). Overall readiness scores ranged from 2.53-3.94; two campuses in preplanning and two in preparation. CONCLUSIONS: Development of the online measure is timely considering the impetus to implement SF/TF policies. Findings reinforce that campuses are at varying stages of implementing these policies, and stage-based interventions are necessary. PMID- 29447623 TI - Community health workers on a college campus: Effects on influenza vaccination. AB - OBJECTIVE: To assess the impact of a campus community health worker program (HealthPALs) on student influenza vaccination. PARTICIPANTS: Undergraduate students at a northeastern US university (enrollment 6650), influenza seasons 2011-2012 through 2015-2016. METHODS: Study design: Difference-in-differences analysis of student vaccination at campus dormitory influenza clinics during intervention vs. baseline. INTERVENTION: In the first intervention year, HealthPALs conducted in-person peer outreach at several campus dormitory flu clinics. Subsequent years, HealthPALs conducted an enhanced intervention, with the addition of a personalized, dormitory-specific social media campaign appealing to students' community identity. RESULTS: The initial intervention increased vaccinations by 66% (IRR = 1.66, 95%CI 1.39-1.97) at intervention clinics relative to control. The enhanced intervention increased vaccinations by 85% (IRR = 1.85, 95%CI 1.75-1.96). CONCLUSION: Community health workers can be a highly effective, low-cost strategy for increasing influenza vaccination among college students. This model could also be used to address other campus health challenges where student engagement is key. PMID- 29447624 TI - Substance use among students in Thailand. AB - This study explored substance use prevalence, level of risk, and associated factors, especially related to binge drinking. A cross-sectional study was conducted among 306 students using questionnaires and the Alcohol, Smoking, and Substance Involvement Screening Test-Youth screening tool. The associations between binge drinking and risk factors were analyzed by generalized linear models. Our results showed current prevalence rates of alcohol, tobacco, and drugs use were 56.9%, 22.9%, and 2.3%, respectively. Multivariate analyses showed that being a binge drinker was significantly associated with low self-efficacy, high sensation seeking, moderate to high smoking risk, and low grade point average. PMID- 29447625 TI - Predicting help-seeking behavior: The impact of knowing someone close who has sought help. AB - OBJECTIVES: This study sought to replicate and extend research on social facilitators of college student's help seeking for psychological problems. PARTICIPANTS: We collected data on 420 ethnically diverse college students at a large public university (September 2008-May 2010). METHODS: Students completed a cross-sectional online survey. RESULTS: We found that students who were aware of close others' (eg, family, friends) help seeking were two times more likely to have sought formal (eg, psychologist) and informal (eg, clergy) help themselves. Tests of moderation revealed the incremental effect (ie, controlling for help seeking attitudes, internalizing symptoms, cultural demographics) of close others' formal help seeking was strong and significant for men (R2 = 0.112), while it was negligible and nonsignificant for women (R2 = .002). CONCLUSIONS: We discuss the importance for students-particularly men-to learn about close others' help seeking for facilitating their own help seeking during times of distress. PMID- 29447626 TI - Psoriasis and wound healing outcomes: A retrospective cohort study examining wound complications and antibiotic use. AB - Little is known about wound healing in psoriasis. We performed a cohort study examining differences in wound healing complications between patients with and without psoriasis. Psoriasis patients with traumatic wounds were matched 1:3 to non-psoriasis patients with traumatic wounds based on age, gender, and body mass index (BMI). We examined theincidence of wound complications including infection, necrosis, and hematoma as well as incident antibiotic use within three months following diagnosis of a traumatic wound. The study included 164 patients with traumatic wounds, comprised of 41 patients with psoriasis matched to 123 patients without psoriasis. No statistically significant differences were detected in the incidence of overall wound complications between wound patients with psoriasis and wound patients without psoriasis (14.6% versus. 13.0%, HR 1.18, CI 0.39 3.56). After adjustment for diabetes, peripheral vascular disease, and smoking, no statistically significant differences were detected in the incidence of overall wound complications between patients with and without psoriasis (HR 1.11, CI 0.34-3.58). Specifically, the adjusted rates of antibiotic use were not significantly different between those with and without psoriasis (HR 0.65, CI 0.29-1.46). The incidence of wound complications following traumatic wounds of the skin was found to be similar between patients with and without psoriasis. PMID- 29447627 TI - Lynch Syndrome and Muir-Torre Syndrome: An update and review on the genetics, epidemiology, and management of two related disorders. AB - Hereditary Nonpolyposis Colorectal Cancer (HNPCC), also known as Lynch Syndrome, is an autosomal dominant, tumor predisposing disorder usuallycaused by germline mutations in mismatch repair (MMR) genes. A subset of HNPCC, Muir-Torre Syndrome (MTS) also involves MMR gene defects and is generally accepted as a variant of HNPCC. MTS is typicallycharacterized by at least one visceral malignancy and one cutaneous neoplasm of sebaceous differentiation, with or without keratoacanthomas. In either version of the disorder, nonfunctional MMR systems lead tothe loss of genomic integrity, marked commonly by mismatches in repetitive DNA sequences, resulting in microsatellite instabilities. Deleterious nucleotide alterations ultimately drive the process of tumorigenesis in both HNPCC and MTS. The following article reviews the epidemiology, genetics, clinical presentation, and management of HNPCC and its MTS variant. PMID- 29447628 TI - Sexual side effects of 5-alpha-reductase inhibitors finasteride and dutasteride: A comprehensive review. AB - The 5-alpha-reductase inhibitors finasteride and dutasteride are frequently used in the treatment of androgenetic alopecia and benign prostatichyperplasia. These drugs are effective at reducing levels of dihydrotestosterone, the primary androgen responsible for the pathogenesis of both these conditions. However, finasteride and dutasteride have also been shown to produce an increase in the incidence of sexual dysfunction, namely, impotence, decreased libido, and ejaculation disorder. The purpose of this study is to review the existing medical literature with regard to the sexual side effects of 5-alpha-reductase inhibitor therapy. This review is an extensive look at the sexual effects of 5-alpha reductase inhibitors and compares outcomes for finasteride versus dutasteride in addition to comparing sexualside effects for each of the different dosages prescribed of finasteride and dutasteride. PMID- 29447629 TI - Wilderness dermatology: mountain exposures. AB - Exploring the mountains is a highly rewarding past time; however, certain high altitude exposures can lead to dermatologic manifestations. In this review article, the authors will describe cold, solar, and severe weather that one may experience when spending time outdoors. Factors such as increased ultraviolet radiation, temperature extremes, and low partial pressure of oxygen, along with human physiologic parameters also contribute to disease severity and presentation. This review article will address the diagnosis, treatment, and prevention of high-altitude dermatology exposures. PMID- 29447630 TI - Metformin as an adjunct therapy for the treatment of moderate to severe acne vulgaris. AB - The purpose of this literature review is to evaluate the use of metformin as an adjunct therapy in the treatment of moderate-to-severe acne in those not diagnosed with polycystic ovary syndrome (PCOS) or androgen excess. The authors conducted independent literature searches. Results were limited to clinical trials and randomized controlled trials. Studies with participants diagnosed with moderateto-severe acne vulgaris taking metformin versus placebo or other active treatment were included;studies with participants diagnosed with PCOS or androgen excess were excluded. The authors found three studies consistent with the search guidelines that evaluated the effects of metformin as adjunct therapy in moderate to severe acne vulgaris. In eachstudy, metformin was an effective adjunct therapy in the treatment of moderate-to-severe acne vulgaris. PMID- 29447631 TI - Does daily folic acid supplementation reduce methotrexate efficacy? AB - Methotrexate is a mainstay treatment for autoimmune and inflammatory conditions in the field of Dermatology. However, in some patients, its use is associated with significant side effects and toxicity. Folate supplementation with either folic acid or folinic acid often mitigates side effects and reduces the incidence of systemic toxicity related to methotrexate. Although the value of methotrexate is clear, debate remains about folate supplementation. There is little agreement about the proper dosing or frequency of folate supplementation as many believe that daily folate supplementation can reduce methotrexate efficacy. Although daily use of folic acid does not appear to affect methotrexate efficacy, dosing of folinic acid close to methotrexate administration may hinder methotrexate efficacy. Therefore, folic acid should be used daily with methotrexate to ameliorate side effects, whereas folinic acid should only be used for methotrexate toxicity. PMID- 29447632 TI - Greater distance to an academic medical center is associated with poorer melanoma prognostic factors: The University of Colorado Experience. AB - INTRODUCTION: Numerous studies report a correlation between distance to diagnostic provider in an academic medical center and poorer prognosis ofdisease. Limited research on this topic exists with respect to melanoma. METHODS: This was a retrospective chart review of 1,463 adults (>=18 years) initially diagnosed with melanoma between 2006-2016. Associations between distance traveled and Breslow depth and presence of metastatic disease were assessed via cumulative and binary logistic regression models, adjusting for patient and tumor characteristics. RESULTS: Subjects traveling >=50 miles had 58% greater odds of having an increased Breslow depth than those traveling less than that distance (OR: 1.58; 95% CI: 1.24-2.01; p<0.0001), and had four times the odds of presenting with metastatic disease (OR: 4.04; 95% CI: 3.00-5.46; p<0.0001). DISCUSSION: We highlight the correlation between increased distance to our academic medical center with greater Breslow depths and the presence ofmetastatic disease at presentation. CONCLUSION: Future studies assessing other factors and regional differences that limit access to diagnosis might help improve screening efforts to prevent poorer prognosis for patients in these areas. PMID- 29447633 TI - Modernizing dermatology interest groups in medical school: Certificate programs. AB - This commentary addresses the increasingly competitive nature of applying to dermatology residency programs and how both interest groups in medical schools and their dermatology departments can help to better prepare applicants. As previous literature argued that dermatology has been underemphasized in medical school curricula, we propose five fundamental options that interest groups can implement in order to offer increased exposure to our field in medical training. Furthermore, with therecent trend of many schools conferring certificates in various specialized concentrations, we also discuss interest groups pioneering certificate-grantingprograms in dermatology competency. The pros and cons of having a recognized certificate program in dermatology are presented. PMID- 29447634 TI - Pityriasis lichenoides-like drug reaction: A clinical histopathologic study of 10 cases. AB - BACKGROUND: Lymphomatoid drug reactions can mimic endogenous T and B cell lymphoproliferative diseases. OBJECTIVES: We present a novel form of cutaneous drug reaction with features of pityriasis lichenoides (PL), a recognized form of T cell dyscrasia. METHODS: Ten cases were studied where a cutaneous eruption exhibiting semblance to PL within a few weeks to months after starting a particular drug. RESULTS: The patient cohort comprised 7 females and 3 males with the mean age of 60 years. Widely distributederythematous cutaneous lesions were present in 6 cases whereas a more localized distribution was seen in three cases. The most frequently implicated drugsassociated with the eruption were antidepressants and statins. Histologic examination showed a morphologic picture identical to PL including marked epitheliotropism of mildly atypical lymphocytes, psoriasiform epidermal hyperplasia, dyskeratosis, hemorrhage, and a thick parakeratotic scale. Therewas a significant reduction in the expression of CD7 and CD62L amid the T cells. Regression of the eruption occurred in all cases excluding one. CONCLUSION: Thefindings conform the categorization of this process as a form of T-cell dyscrasia albeit one that is reversible, dependent on the drug withdrawal. The limitationof our study includes the retrospective design of the study. PMID- 29447635 TI - Sublamina densa-type linear IgA bullous dermatosis with IgA autoantibodies specific for type VII collagen: a case report and clinicopathological review of 32 cases. AB - Linear IgA bullous dermatosis (LABD) is a rare autoimmune bullous disorder characterized by linear deposits of IgA at the basement membrane zone(BMZ) and/or by circulating IgA anti-BMZ antibodies. Comparing with other immuno-bullous diseases, LABD represents a heterogeneous disease entitywith diversity of pathogenic IgA autoantibodies to different hemidesmosomal antigens and an association with malignancies and occasional drug use. We herein present an 82 year-old Japanese man with LABD, whose indirect immunofluorescence using 1M NaCl split skin showed positive staining for IgA at the dermal side alone. Fluorescence overlay antigen mapping using laser scanning confocal microscopy (FOAM-LSCM) was employed to examine the in vivo bound patient's IgA, which was specific for type VII collagen (COL7), a prominent antigen of the sublamina densa. One year later, he developed malignant lymphoma, suggesting the diagnosis of paraneoplastic LABD. We reviewed 32 cases of sublamina-densa type LABD with anti-COL7 IgA antibodies thus far reported in the literature to compare the clinicopathological characteristics of this rare disease variant and emphasize that COL7 is the main autoantigen in sublamina densa disease. PMID- 29447636 TI - A diagnostically challenging case of CD8+ primary cutaneous gamma/delta T-cell lymphoma. AB - Primary cutaneous gamma/delta T-cell lymphoma (PCgammadeltaTCL) is a rare form of cutaneous lymphoma characterized by abnormal clonal proliferation of mature, activated gamma-delta T cells expressing the gammadelta heterodimer of the T-cell receptor (TCR). As an entity, PCgammadeltaTCL has recently undergone diagnostic revision since its introduction in the 2008 WHO classification of cutaneous lymphomas and confirmedin 2016. Nonetheless, diagnosis remains difficult both clinically and histologically, given its broad range of clinical manifestations and immunohistochemical phenotypes. Herein, we present a rare case of CD8+ PCgammadeltaTCL with a discussion highlighting theheterogeneity within this entity. PMID- 29447637 TI - Crohn disease-associated neutrophilic urticarial dermatosis: report and literature review of neutrophilic urticarial dermatosis. AB - Neutrophilic urticarial dermatosis (NUD) is a useful diagnostic term for urticarial lesions that are less pruritic and more painful than conventional urticaria. The histopathologic features include neutrophilic infiltrates in the interstitial dermis with a higher density than idiopathic urticaria. NUD has been associated with several systemic conditions, which are predominantly autoimmune and autoinflammatory in nature. A woman with Crohn disease who developed NUD is described. Literature reports of other conditions in which neutrophilic urticarial dermatosis have been observed are also reviewed and summarized. NUD has not only been described in the setting of inflammatory bowel disease, but also in patients who have systemic lupus erythematosus, adult-onset Still disease, and IgA gammopathy. NUD is usually associated with an underlying disease. Therapeutic agents that target neutrophils (such as dapsone and colchicine) and antagonists to interleukin-1 receptor (such as anakinra) may be effective modalities for affected patients. NUD can be added to the list of dermatologic manifestations associated with systemic inflammation, particularly inflammatory bowel disease. PMID- 29447638 TI - Pediatric pustular psoriasis responsive to cyclosporine bridged to etanercept: A treatment approach. AB - Pustular psoriasis occurs rarely in children but can present with acute toxicity requiring inpatient admission. For the best approach, medical providers should have an evidence based and systematic treatment algorithm in their armamentarium. Toillustrate this point, we describe a 13-year-old girl who was admitted with generalized pustular psoriasis and who responded dramatically to "wet wrap" therapy and cyclosporine bridged to etanercept. Using this case example, we highlight the three most important considerations in any patient with new onset pustularpsoriasis: avoidance of disease complications, acute "rescue" therapy, and maintenance therapy. PMID- 29447639 TI - A patient case highlighting the myriad of cutaneous adverse effects of prolonged use of hydroxyurea. AB - BACKGROUND: Hydroxyurea is an antimetabolite primarily used to treat myeloproliferative disorders, and chronic treatment is associated with many cutaneous adverse effects ranging in severity from ichthyosis to aggressive nonmelanoma skin cancer. CASE PRESENTATION: We report a 67-year-oldman with a history of polycythemia vera who was referred for management of progressively worsening dorsal hand lesions. The patient presented withhyperpigmentation, ichthyosis, plantar keratoderma, dermatomyositis-like eruptions, two squamous cell carcinomas, and actinic keratoses. The adversereactions observed were acknowledged to be related to chronic hydroxyurea use. The patient underwent Mohs excision of the squamous cell carcinomas and thehydroxyurea was promptly discontinued; subsequent cutaneous improvement of the dermatomyositislike lesions ensued. Another clinically suspicious aggressive squamous cell carcinoma was suspected and the patient was referred to the plastic surgery department for complete excision because of the size of the lesion. The patient remains on periodic dermatology follow up. CONCLUSIONS: We report a case that exemplifies the cutaneous adverse effects of chronic hydroxyurea therapy. Although many cases improve after drug discontinuation, strict photoprotection and ongoing surveillance are indicated given the recently proposed premalignant potential of dermatomyositis-like eruptions and the aggressive nature of hydroxyurea-induced nonmelanoma skin cancer. PMID- 29447640 TI - Classic form of eosinophilic pustular folliculitis in an immunocompetent girl: rapid and complete resolution after low-dose oral indomethacin treatment. AB - Eosinophilic pustular folliculitis (EPF) is a rare noninfectious pruritic dermatosis, first described by Ise and Ofuji in 1965. We report the case of a 15 year oldimmunocompetent girl that presented with a widespread papulopustular eruption four days after her arrival in Japan. The clinical diagnosis of the classicform of EPF was confirmed by histological examination of the lesional skin that revealed an intense, mainly eosinophilic, dermal infiltrate within and aroundpilosebaceous units. Oral administration of lowdose indomethacin (25 mg/day) led to a complete resolution of the eruption within 6 weeks without causing any side effects. The patient is presently completing a 15-month follow up and remains free ofrelapses. To the best of our knowledge, it is the first time that low-dose oral indomethacin is reported to be capable of causing a rapid and complete resolutionof the classic form of EPF. PMID- 29447641 TI - Flame figures in linear IgA bullous dermatosis: a novel histopathologic finding. AB - BACKGROUND: Linear IgA bullous dermatosis (LABD) is an autoimmune subepidermal blistering disease usually with a neutrophil rich inflammatory infiltrate, and characterized by linear IgA deposition at the basement membrane zone (BMZ), and neutrophil predominant dermal inflammation. We report a case of LABD with numerous eosinophils and flame figure formation, a unique histopathologic finding not previously reported. A 69-year-old woman presented with a rapidly progressive, intensely pruritic rash over forearms, breasts, axillae, hips, and thighs. Thelesions were comprised of annular vesicles and bullae with hemorrhagic crusts and erosions. The clinical differential diagnosis included bullous pemphigoid(BP), LABD, and epidermolysis bullosa aquisita (EBA). RESULTS: A biopsy from a bullous plaque on the wrist revealed a subepidermal blister with neutrophils and numerous eosinophils with flame figure formation.Direct immunofluorescent (DIF) microscopy revealed linear deposition of IgA at the BMZ. CONCLUSIONS: Although unusual, the combined findings supported a diagnosis of LABD. Increased eosinophils may be associated with drug-induced LABD and may explain the numerous eosinophils in our case. It is important to be aware of this finding as the pathology may easily be misdiagnosed as BP, or possibly bullousWells syndrome. This case emphasizes that combined clinical, pathologic, and DIF findings are essential in the diagnosis of bullous dermatoses. PMID- 29447642 TI - Is it just a psoriasiform dermatitis? AB - Bazex syndrome (BS) is a rare paraneoplastic syndrome most frequently associated with squamous cell carcinomas of the upper aerodigestive tractand other tumours. Characteristically, cutaneous lesions precede the diagnosis of malignancy. We report a 72-year-old patient with 1-year history of acral dermatitis. The diagnosis of BS was based on the presence of psoriasiform acral dermatitis and the evidence of two simultaneous tumors (prostate adenocarcinoma and undifferentiated carcinoma ofthe submandibular gland). It is important to have this syndrome in mind since cutaneous features usually precede an underlying neoplasm. PMID- 29447643 TI - A case of leukocytoclastic vasculitis caused by novel anticoagulant rivaroxaban. AB - Cutaneous leukocytoclastic vasculitis (LCV) is type of small vessel vasculitis that commonly presents as palpable purpura involving the lower extremities and buttocks. Approximately half of cases are idiopathic, but the disease may be triggered by infection, drug reaction, inflammatory disease, or other causes. We report a case of leukocytoclastic vasculitis secondary to the novel anticoagulant rivaroxaban (Xarelto(r)). PMID- 29447644 TI - Cutaneous metastasis to the scalp as the primary presentation of colorectal adenocarcinoma. AB - Eruptaneous metastasis is an uncommon presentation of colorectal adenocarcinoma that can occur years after diagnosis of the primary cancer or manifest as the first sign of malignancy. It is essential to diagnose these metastases immediately, as this late-stage development carries a poor prognosis. The scalp is one of the less common sites for skin metastases and nodules may be mistaken for benign entities. In this case report, we report on the case of a 61-year-old woman with CREST syndrome who presented with a cutaneous metastasis to the scalp as the first sign ofcolorectal adenocarcinoma. PMID- 29447645 TI - Vulvar metastatic Crohn disease: clinical, histopathological and ultrasonographic findings. AB - Metastatic Crohn disease (MCD) is an unusual type of cutaneous Crohn disease characterized by skin lesions separated from the lesions of the gastrointestinal tract. The diagnosis of MCD is essentially histological,showing noncaseating granulomas in the dermis and subcutaneous fat tissue. We report a case of MCD with vulvar involvement and clinical, histopathological, and ultrasonographic findings of this disease. PMID- 29447646 TI - Lichen amyloidosis of the scalp and forehead. AB - Lichen amyloidosis is a subtype of primary localized cutaneous amyloidosis (PLCA), which presents as discrete, firm, closely-set 1-3mm, dome-shapedbrown papules commonly involving the anterior aspect of shins and extensor surfaces of forearms. We present a case of an otherwise healthy man in his 30s with solitary facial involvement of lichen amyloidosis, which is very uncommon. PMID- 29447647 TI - Association of pemphigus and systemic corticosteroid use with comorbid health disorders: A case-control study. AB - BACKGROUND: Pemphigus is a group of debilitating autoimmune blistering disorders associated with painful blisters of the skin and/or mucous membranes. Identification and management of the comorbiditiesof pemphigus is critically important to minimize morbidity and decrease mortality. OBJECTIVE: To identify the comorbid health conditions of pemphigus vulgaris. METHODS: This was a case control study of 130 cases of pemphigus verified by a clinical and laboratory diagnosis and 390 age and sex-matched controls with complete follow-up at a large metropolitanquaternary care medical center. RESULTS: Pemphigus vulgaris and its treatments were significantly associated with type 2 diabetes mellitus (adjusted odds ratio [95% confidence interval]: 5.68 [2.93-11.02]), hypertension (2.15 [1.25-3.71]), osteopenia (10.07 [3.72-27.25]), osteoporosis (4.19 [1.50-11.73]), cataracts (7.00 [1.81-27.07]), insomnia (15.00 [1.75-128.39]), and benign prostatic hyperplasia (6.84 [1.79-26.18]). A history of taking systemic corticosteroids was found in 76% of pemphigus vulgaris patients. There were significant statistical interactions between pemphigus vulgaris and a history of using systemic corticosteroids as predictors of diabetes mellitus type 2, hypertension, osteoporosis, and insomnia. CONCLUSIONS: Safer and more effective systemic treatment options are needed for pemphigus to minimize iatrogenic complications of disease. PMID- 29447648 TI - Dermatology Medical Education: A Multicenter Survey Study of the Undergraduate Perspective of the Dermatology Clinical Clerkship. AB - BACKGROUND/AIMS: Limited data are available regarding the undergraduate dermatology clinical clerkship curriculum in the United States. Our primaryaim is to assess medical students' perspectives of the dermatology clinical clerkship. METHODS: A multicenter survey study was conducted, which included four California dermatology academic programs. A 17-item questionnaire was designed to investigate medical student perception with regard tothe overall educational value of the various teaching aspects of the dermatology clinical clerkship. RESULTS: A total of 152 medical student surveys were completed. Over half of the medical students felt proficient in diagnosing the most commondermatologic conditions. Eighty-seven percent of medical students were very satisfied with the dermatology clerkship. Ninety-one percent of students felt the length of the clerkship was appropriate. CONCLUSIONS: The vast majority of medical students reported a high level of proficiency in the treatment and diagnosis of common skin disorders. In contrast, our findings suggest that medical students may not begaining sufficient hands-on experience in conducting certain dermatologic procedures following the dermatology clerkship. Overall, medical studentperception of the dermatology clinical clerkship was mostly positive. PMID- 29447649 TI - A national cross-sectional analysis of dermatology away rotations using the Visiting Student Application Service database. AB - The highly competitive nature of the dermatology match requires applicants to undertake a variety of measures in the hopes of securing a residency position. Among the opportunities available to applicants is the chance to participate in away or "audition" rotations during their final year of undergraduate medical education. Away rotations are now performed by a majority of medical students applying into dermatology, but littleresearch has been done to describe the nature of this opportunity for interested applicants. An analysis of all dermatology electives offered in the Visiting Student Application Service (VSAS) database wasperformed. Results indicate that students have the option to pursue electives in a variety of subjects offered by 100 sponsoring institutions spread across a wide geographic distribution. Although manyopportunities exist, this analysis sheds light on several areas for improving the quality of this experience for interested applicants, including providing more electives in advanced subject matter, permitting more flexibility in scheduling, and promoting wider participation in VSAS. PMID- 29447650 TI - Characteristics of research tracks in dermatology residency programs: a national survey. AB - Pursuing research is encouraged in dermatology residency programs. Some programs offer specific research or investigative tracks. Currently, there is little data on the structure or scope of research tracks in dermatology residency programs. An anonymous online survey was distributed to the Association of Professors of Dermatology listserve in 2016. Program directors of dermatology residency programs in the United States were asked to participate and 38 of the 95 program directors responded. The survey results confirmed that a 2+2 research track, which is two years of clinical training followed by two years of research, was the most common investigator trackmodel and may promote an academic career at the resident's home institution. Further studies will help determine the most effective research track models to promote long-term outcomes. PMID- 29447651 TI - Elective time during dermatology residency: A survey of residents and program directors. AB - Elective time during residency training provides residents with exposure to different subspecialties. This opportunity gives residents the chance tonurture growth in particular areas of interest and broaden their knowledge base in certain topics in dermatology by having the chance to work withexperts in the field. The purpose of this study was to assess the views of residency program directors and dermatology residents on the value of elective time through a cross sectional survey. An eight-questionIRB exempt survey was sent out to 113 residency program directors via email through the American Professors of Dermatology (APD) program director listserv. Program directors were asked to forward a separate set of 9 questions to their residents. The majority of programs that responded allowed for some elective time within their schedule, often duringthe PGY 4 (3rd year of dermatology training), but the amount of time allowed widely varied among many residency programs. Overall, residents and program directors agree that elective is important in residencytraining, but no standardization is established across programs. PMID- 29447652 TI - Pyoderma gangrenosum, acne, and suppurative hidradenitis syndrome in end-stage renal disease successfully treated with adalimumab. AB - PASH syndrome (pyoderma gangrenosum, acne, and suppurative hidradenitis) forms part of the spectrum of autoinflammatory diseases. We report an unusual case of PASH syndrome in a patient with end-stagerenal disease (ESRD) who was successfully treated with the tumor necrosis factor inhibitor, adalimumab. The case underscores the challenges associatedwith the treatment of PASH syndrome as well as the ongoing search to establish a genetic basis for the syndrome. Renal impairment has been reported in association with pyoderma gangrenosum but has notbeen described in PASH syndrome. We believe this to be the first reported case of a patient who developed PASH syndrome in the setting of ESRD. PMID- 29447653 TI - Rituximab and intravenous immunoglobulin as alternatives to long-term systemic corticosteroids in the treatment of pemphigus: a single center case series of 63 patients. AB - Rituximab and intravenous immunoglobulin [IVIg] have recently emerged as effective treatments for pemphigus refractory to corticosteroids [CS]. This case series sought to compare the clinical, serologic,and adverse effects of CS, IVIg, and rituximab in patients with pemphigus. A retrospective review of 63 patients with pemphigus vulgaris (PV), pemphigus foliaceus (PF), or paraneoplastic pemphigus (PNP)was performed. Clinical remission (CR), serologic remission (SR), and adverse effects were evaluated. Three study groups were compared: patients treated with systemic CS, refractory patients treated withIVIg, and refractory patients treated with rituximab. The overall number of adverse effects was not significantly different between the groups but those observed in patients treated with systemic CS weremore severe. CR was less likely in the patients treated with systemic CS than in patients treated with IVIg or rituximab, P-value = 0.000467. SR was more likely in patients treated with systemic CS or rituximab thanin patients treated with IVIg, P-value = 0.002118. These results suggest that the clinical efficacy of IVIg is not correlated with an expected concomitant SR. Frequently reserved for refractory pemphigus,IVIg and rituximab are significantly more likely to produce clinical remission than systemic CS therapy, suggesting their utility as first-line treatments. PMID- 29447654 TI - Papular mucinosis, or localized lichen myxedematosis (LM) (discrete papular type). AB - Lichen myxedematosus is condition characterized by localized areas of dermal deposition of mucin, presenting with firm papules localized to few areas of the body. The condition needs to be excluded from scleromyxedema, which, in addition to the firm papular eruption, has areas of induration and is usually associated with a monoclonal gammopathyand systemic symptoms. We present a 62-year-old woman with a several-year history of asymptomatic, firm papules over the face and arms with no evidence of thyroid disease or a monoclonal gammopathy,which is consistent with a diagnosis of localized lichen myxedematosus, the discrete papular variant. The patient is being treated with a topical calcineurininhibitor. PMID- 29447655 TI - Epidermolysis bullosa acquisita. AB - Epidermolysis bullosa acquisita (EBA) is a rare, acquired subepidermal blistering disease. EBA is characterized by autoantibodies to collagen VII,which serves to link the epidermis to the dermis. The two most common presentations of EBA are classical noninflammatory EBA and bullous pemphigoid-like EBA. Diagnosis of EBA can be challenging as it sharesclinical and histopathologic features with other blistering diseases. Treatment is often recalcitrant and will often necessitate multiple therapies. We presenta case of a thirty-six-year-old Chinese man with EBA and review the literature. PMID- 29447656 TI - Local heat urticaria. AB - We present a 38-year-old woman with local heat urticaria confirmed by heat provocation testing. Heat urticaria is a rare form of physical urticaria that istriggered by exposure to a heat source, such as hot water or sunlight. Although it is commonly localized and immediate, generalized and delayed onset forms exist. Treatment options include antihistamines and heat desensitization. A brisk, mechanical stroke elicited a linear wheal. Five minutes after exposure to hot water, she developed well-demarcated,erythematous blanching wheals that covered the distal forearm and entire hand. PMID- 29447657 TI - Generalized hyperhidrosis secondary to presumed eccrine gland dysfunction with possible apocrine metaplasia. AB - We present a 57 year-old man presented with generalized hyperhidrosis and widespread, smooth, flesh colored papules on the torso and extremities.Histological examination from multiple biopsies demonstrated morphologic alteration of the eccrine glands with an apocrine phenotype, suggesting eitherapocrine metaplasia or the presence of "apoeccrine glands." The morphologic similarities between eccrine, apocrine, and apoeccrine as they relate to ourpatient's histologic findings are discussed. We consider secondary causes of generalized hyperhidrosis, which may also play a role in this patient's presentation. Treatment and further workup are discussed, whilemanagement of this patient remains in progress. PMID- 29447658 TI - Primary anetoderma with undifferentiated connective tissue disease. AB - Anetoderma is a rare benign elastolytic disorder that is characterized by focal loss of elastin fibers on histopathology and is often recalcitrant to treatment. We present a case of a patient with a 20-year history of pruritic and painful hyperpigmented atrophic papules clustered on the neck, axillae, inframammary folds, and right medial thigh. Although the histopathologyof her axillary lesions was consistent with anetoderma, her clinical presentation is unusual given the extent of involvement, reported pain and pruritus, and sharp demarcation of the distribution. The diagnosticuncertainty of this case led to added difficulty in management of a disease that is already notoriously difficult to treat and may significantly impact patient's quality of life. PMID- 29447659 TI - Paraneoplastic Pemphigus in a 34-year-old. AB - Paraneoplastic Pemphigus (PNP) is a rare and often fatal autoimmune mucocutaneous blistering disease associated with an underlying malignancy. It is thought to be caused by antibodies to tumor antigenscross-reacting with epithelial antigens, specifically desmosomal and hemidesmosomal antigens. There are at least five clinical morphologic variants of PNP, with the earliest and most consistent finding beingsevere stomatitis. Diagnosis of PNP requires direct immunofluorescence of perilesional skin and indirect immunofluorescence. Treatment of PNP is difficult and largely limited to glucocorticoids, steroid sparing immunomodulators, rituximab and intravenous immunoglobulin (IVIG). Despite therapies, prognosis is poor. We report a case of paraneoplastic pemphigus in a 34-year old male with severe stomatitis and lichenplanus-like cutaneous lesions. PMID- 29447660 TI - Expanded carrier screening: what the reproductive endocrinologist needs to know. AB - Expanded carrier screening refers to identification of carriers of single-gene disorders outside of traditional screening guidelines. New genetic testing technologies allow for such screening at costs that are comparable to single-gene testing. There is a high degree of variability among genetic testing laboratories as to the inclusion of different disorders, some of which have mild or unpredictable phenotypes. This review discusses the pros and cons of using expanded carrier screening in the preconceptional patient and reviews guidelines currently endorsed by professional organizations. PMID- 29447661 TI - Ethical quandaries around expanded carrier screening in third-party reproduction. AB - Although current screening methods of gamete donors are capable of reducing the incidence of genetic anomalies in donor offspring below general population levels, targeted screening for a large number of conditions (expanded carrier screening or ECS) could be considered as part of the routine selection procedure for gamete donors. There are, however, important drawbacks to its practical implementation. Excluding all carriers of severe recessive monogenic pediatric disorders would disqualify virtually all donors, and other approaches negatively affect cost (and therefore access), present dilemmas in regard to disclosure of genetic findings, and/or overburden the intended parents. In all of the scenarios considered, adequate genetic counseling will be of central importance. Besides looking at benefits and drawbacks of possible ways of implementing ECS, we also examine whether a moral obligation exists to adopt ECS at all and on whose shoulders such an alleged obligation would rest: policymakers, medical staff at fertility clinics, sperm and egg banks, the intended parents? We argue that given the small risk reduction brought about by ECS, the possible negative effects of its implementation, and the absence of widespread preconception carrier screening in the general population, it is inconsistent to argue that there is a moral obligation to perform ECS in the context of donor conception. Finally, implications for the donors are discussed. PMID- 29447662 TI - Cell-free DNA for the detection of fetal aneuploidy. AB - Screening for fetal aneuploidy via cell-free DNA was described more than two decades ago and has been used clinically by obstetric providers in the United States for more than 5 years. Cell-free DNA affords excellent detection of fetal Down syndrome and other common aneuploidies and thus is sought by patients and providers. However, owing to the source of the DNA and the nature of the screening test, scenarios may arise that require expert counseling about complex issues regarding fetal and maternal health, test interpretation, and management. It is essential that infertility specialists understand the specific issues related to the strengths and limitations of this screening test, especially in light of expanded genetic testing of embryos. PMID- 29447664 TI - Prevention of in vitro fertilization twins should focus on maximizing single embryo transfer versus twins are an acceptable complication of in vitro fertilization. PMID- 29447663 TI - Prenatal diagnosis by chromosomal microarray analysis. AB - Chromosomal microarray analysis (CMA) is performed either by array comparative genomic hybridization or by using a single nucleotide polymorphism array. In the prenatal setting, CMA is on par with traditional karyotyping for detection of major chromosomal imbalances such as aneuploidy and unbalanced rearrangements. CMA offers additional diagnostic benefits by revealing sub-microscopic imbalances or copy number variations that are too small to be seen on a standard G-banded chromosome preparation. These submicroscopic imbalances are also referred to as microdeletions and microduplications, particularly when they include specific genomic regions that are associated with clinical sequelae. Not all microdeletions/duplications are associated with adverse clinical phenotypes and in many cases, their presence is benign. In other cases, they are associated with a spectrum of clinical phenotypes that may range from benign to severe, while in some situations, the clinical significance may simply be unknown. These scenarios present a challenge for prenatal diagnosis, and genetic counseling prior to prenatal CMA greatly facilitates delivery of complex results. In prenatal diagnostic samples with a normal karyotype, chromosomal microarray will diagnose a clinically significant subchromosomal deletion or duplication in approximately 1% of structurally normal pregnancies and 6% with a structural anomaly. Pre-test counseling is also necessary to distinguish the primary differences between the benefits, limitations and diagnostic scope of CMA versus the powerful but limited screening nature of non-invasive prenatal diagnosis using cell-free fetal DNA. PMID- 29447665 TI - Preparation of molecularly imprinted polymer nanobeads for selective sensing of carboxylic acid vapors. AB - The detection and discrimination of volatile carboxylic acid components, which are the main contributors to human body odor, have a wide range of potential applications. Here, a quartz crystal microbalance (QCM) sensor array based on molecularly imprinted polymer (MIP) nanobeads is developed for highly sensitive and selective sensing of typical carboxylic acid vapors, namely: propionic acid (PA), hexanoic acid (HA) and octanoic acid (OA). The MIP nanobeads were prepared by precipitation polymerization with methacrylic acid (MAA) as a functional monomer, trimethylolproane trimethacrylate (TRIM) as a crosslinker, and carboxylic acids (PA, HA and OA) as the template molecules. The precipitation polymerization resulted in nano-sized (150-200 nm) polymer beads with a regular shape. The polymerization conditions were optimized to give a functional monomer, crosslinker, and template ratio of 1:1:2. We investigated the imprinting effect using both QCM and GC/MS measurements comparing vapor absorption characteristics between the imprinted and non-imprinted (NIP) nanobeads. A four-channel QCM sensory array based on the NIP and the three types of MIP nanobeads was fabricated for sensing the three types of carboxylic acid vapor at concentrations on the ppm level. The output of the sensor array was analyzed by both a non supervised method (principle component analysis: PCA) and supervised method (linear discrimination analysis: LDA). LDA showed a better discrimination ability than PCA. A 96%-classification rate was achieved by applying leave-one-out cross validation to the LDA model. The high sensitivity and selectivity of the sensor array was attributed to the imprinting effect of the nano-sized polymer beads. The developed MIP nanobeads, together with other types of MIPs, show promise as materials for artificial receptors in vapor and odorant sensing. PMID- 29447666 TI - Trace determination of antimony by hydride generation atomic absorption spectrometry with analyte preconcentration/atomization in a dielectric barrier discharge atomizer. AB - Atomization conditions for antimony hydride in the plasma atomizer based on a dielectric barrier discharge (DBD) with atomic absorption spectrometric detection were optimized. Argon was found as the best discharge gas under a flow rate of 50 mL min- 1 while the DBD power was optimum at 30 W. Analytical figures of merit including interference study of As, Se and Bi have been subsequently investigated and the results compared to those found in an externally heated quartz tube atomizer (QTA). The limit of detection (LOD) reached in DBD (0.15 ng mL-1 Sb) is comparable to that observed in QTA (0.14 ng mL-1 Sb). Finally, possibility of Sb preconcentration by stibane in situ trapping in a DBD atomizer was studied. For trapping time of 300 s, the preconcentration efficiency and LOD, respectively, were 103 +/- 2% and 0.02 ng mL-1. PMID- 29447667 TI - Feature expansion by a continuous restricted Boltzmann machine for near-infrared spectrometric calibration. AB - A modified algorithm for training a restricted Boltzmann machine (RBM) has been devised and demonstrated for improving the results for partial least squares (PLS) calibration of wheat and meat by near-infrared (NIR) spectroscopy. In all cases, the PLS calibrations improved by using the abstract features generated from the RBM so long as the nonlinear mapping increased the dimensionality. The evaluations were validated using bootstrapped Latin partitions (BLPs) with 5 bootstraps and 3-Latin partitions which proved useful because of the statistical learning and random initial conditions of the RBM networks. By using a noise decay parameter, initial large amounts of noise could be used and the benefits of simulated annealing achieved as the noise level is slowly decreased. This paper demonstrates for the first time that using abstract features and enlarging the spectral data can improve the calibration results and exemplifies the Copiosity Principle. Two NIR reference datasets were evaluated. The first set of wheat spectra was calibrated for protein concentration and the second set of meat spectra was calibrated for moisture, fat, and protein concentration. The RBM feature extraction improved the linearity of the models and reduced embedded noise. The RBM also can help eliminate some difficult spectral preprocessing stages such as variable alignment and feature selection. RBMs benefit from derivative preprocessing of the NIR spectra or other preprocessing that enhances the differences among the spectra. PMID- 29447668 TI - A simple and automated sample preparation system for subsequent halogens determination: Combustion followed by pyrohydrolysis. AB - A simple and automated system based on combustion followed by a pyrohydrolysis reaction was proposed for further halogens determination. This system was applied for digestion of soils containing high (90%) and also low (10%) organic matter content for further halogens determination. The following parameters were evaluated: sample mass, use of microcrystalline cellulose and heating time. For analytes absorption, a diluted alkaline solution (6 mL of 25 mmol L-1 NH4OH) was used in all experiments. Up to 400 mg of soil with high organic matter content and 100 mg of soil with low organic matter content (mixed with 400 mg of cellulose) could be completely digested using the proposed system. Quantitative results for all halogens were obtained using less than 12 min of sample preparation step (about 1.8 min for sample combustion and 10 min for pyrohydrolysis). The accuracy was evaluated using a certified reference material of coal and spiked samples. No statistical difference was observed between the certified values and results obtained by the proposed method. Additionally, the recoveries obtained using spiked samples were in the range of 98-103% with relative standard deviation values lower than 5%. The limits of quantification obtained for F, Cl, Br and I for soil with high (400 mg of soil) and low (100 mg of soil) organic matter were in the range of 0.01-2 MUg g-1 and 0.07-59 MUg g-1, respectively. The proposed system was considered as a simple and suitable alternative for soils digestion for further halogens determination by ion chromatography and inductively coupled plasma mass spectrometry techniques.

AB - Glucose enzyme biosensors have been used for a variety of applications such as medical diagnosis, bioprocess engineering, beverage industry and environmental scanning etc. and there is still a growing interest in glucose sensors. For this purpose, addressed herein, as a novel glucose sensor, highly sensitive activated carbon (AC) decorated monodisperse nickel and palladium alloy nanocomposites modified glassy carbon electrode (Ni-Pd@AC/GCE NCs) have been synthesized by in situ reduction technique. Raman Spectroscopy (RS), X-ray Photoelectron Spectroscopy (XPS), X-ray Diffraction (XRD), Transmission Electron Microscopy (TEM), cyclic voltammetry (CV) and chronoamperometry (CA) were used for the characterization of the prepared non-enzymatic glucose sensor. The characteristic sensor properties of the Ni-Pd@AC/GCE electrode were compared with Ni-Pd NCs/GCE, Ni@AC/GCE and Pd@AC/GCE and the results demonstrate that the AC is very effective in the enhancement of the electrocatalytic properties of sensor. In addition, the Ni-Pd@AC/GCE nanocomposites showed a very low detection limit of 0.014 MUM, a wide linear range of 0.01 mM-1 mM and a very high sensitivity of 90 mA mM-1 cm-2. Furthermore, the recommended sensor offer the various advantageous such as facile preparation, fast response time, high selectivity and sensitivity. Lastly, monodisperse Ni-Pd@AC/GCE was utilized to detect glucose in real sample species.

AB - Thermal desorption electrospray ionization/mass spectrometry (TD-ESI-MS) employing a quickly interchangeable ionization source is a relatively new ambient ionization mass spectrometric technique that has had, to date, only a limited number of applications related to food safety control. With reallocation of resources, this direct-analysis technique has had wider use in food analysis when operated in dual-working mode (pretreatment-free qualitative screening and conventional quantitative confirmation) after switching to an ambient ionization source from a traditional atmospheric pressure ionization source. Herein, we describe the benefits and challenges associated with the use of a TD-ESI source to detect adulterants in processed vegetables (PVs), as a proof-of-concept for the detection of basic colorants. While TD-ESI can offer direct qualitative screening analyses for PVs with detection capabilities lower than those provided with liquid chromatography/UV detection within 30 s, the use of TD-ESI for semi quantification is applicable only for homogeneous food matrices. PMID- 29447671 TI - Label-free and sensitive microRNA detection based on a target recycling amplification-integrated superlong poly(thymine)-hosted copper nanoparticle strategy. AB - Poly(thymine)-hosted copper nanoparticles (poly T-CuNPs) have emerged as a promising label-free fluorophore for bioanalysis, but its application in RNA related studies is still rarely explored. Herein, by utilizing duplex-specific nuclease (DSN) as a convertor to integrate target recycling mechanism into terminal deoxynucleotidyl transferase (TdT)-mediated superlong poly T-CuNPs platform, a specific and sensitive method for microRNA detection has been developed. In this strategy, a 3'-phosphorylated DNA probe can hybridize with target RNA and then be cut by DSN to produce 3'-hydroxylated fragments, which can be further tailed by TdT with superlong poly T for fluorescent CuNPs synthesis. As proof of concept, an analysis of let-7d was achieved with a good linear correlation between 20 and 1000 pM (R2 = 0.9965) and a detection limit of 20 pM. Moreover, both homologous and heterologous microRNAs were also effectively discriminated. This strategy might pave a brand-new way for designing label-free and sensitive microRNA assays. PMID- 29447672 TI - Formulation of DNA chimera templates: Effects on emission behavior of silver nanoclusters and sensing. AB - Single strand DNA (ssDNA) chimeras consisting of a silver nanoclusters-nucleating sequence (NC) and an aptamer are widely employed to synthesize functional silver nanoclusters (AgNCs) for sensing purpose. Despite its simplicity, this chimeric templated AgNCs often leads to undesirable turn-off effect, which may suffer from false positive signals caused by interference. In our effort to elucidate how the relative position of NC and aptamer affects the fluorescence behavior and sensing performance, we systematically formulated these NC and aptamer regions at different position in a DNA chimera. Using adenosine aptamer as a model, we tested the adenosine-induced optical response of each design. We also investigated the effect of linker region connecting NC and aptamer, as well as different NC sequence on the sensing performance. We concluded that locating NC sequence at 5'-end exhibited the best response, with immediate fluorescence enhancement observed over a wide linear range (1-2500 MUM). Our experimental findings help to explain the emission behavior and sensing performance of chimeric conjugates of AgNCs, providing an important means to formulate a better aptasensor. PMID- 29447673 TI - A regenerated "turn on" fluorescent probe for sulfide detection in live cells and read samples based on dihydroxyhemicyanine-Cu2+ dye. AB - A novel "turn-on" fluorescence probe (HHC)2-Cu2+ for sulfide (S2-) was synthesized and characterized based on dihydroxyhemicyanine-Cu2+ complex. The probe displayed high sensitivity and selectivity for S2- over other analytes, including biothiols, NaCN, reactive oxygen species (ROS) and reactive nitrogen species (RNS) in aqueous solution, which was attributed to the large association constant and the fast kinetics of precipitation of CuS. The probe (HHC)2-Cu2+ can be regenerated and reversibly detected with S2- with a remarkable red-fluorescent change by alternating the addition of S2- and Cu2+. Fluorescent spectra of (HHC)2 Cu2+ toward S2- showed a high selectivity, a good linearity, a low limit of detection at 0.12 MUM, a rapid response time (less than 30 s), and a wide pH range of 7-10. Importantly, the probe was successfully applied to detect the low level of S2- in waste water samples, corrupt blood samples, and living cells. PMID- 29447674 TI - Green-modified micellar liquid chromatography for isocratic isolation of some cardiovascular drugs with different polarities through experimental design approach. AB - Bilayer pseudo-stationary phase micellar liquid chromatography (MLC) was developed for simultaneous isocratic isolation of hydrochlorothiazide, as a basic polar (hydrophilic) cardiovascular drug, as well as triamterene and losartan potassium, as acidic-nonpolar (hydrophobic) cardiovascular drugs. Utilizing a deep eutectic solvent (DES), as a novel green mobile phase additive in combination with acetonitrile (ACN) and acetic acid (ACA), drastically improved the chromatographic behavior of the drugs. Concentration of sodium dodecyl sulphate (SDS), as well as volume percentages of ACN, DES, and ACA were optimized by using a central composite design. The optimal composition of the mobile phase (0.12 mol L-1 SDS, 5% ACN, 4% DES, and 2% ACA) was chosen through the desirability function. The chromatographic peaks of both hydrophilic and hydrophobic drugs, respectively, emerged at high and low retention time values in the shortest total analysis time of 20 min (at a flow rate of 2 mL min-1). Analytical characterization of the developed approach was investigated through Food and Drug Administration (FDA) guidelines. Applicability of the method was evaluated by analysing of human plasma samples which were directly injected into the system. PMID- 29447675 TI - Quantitative determination of non-lactose milk oligosaccharides. AB - A method for the determination of non-lactose oligosaccharides (NLO) in milk using liquid chromatography has been developed. Oligosaccharides were labelled with a fluorescent tag, 2-aminobenzamide (2AB), and were identified by comparison of their retention times to those of oligosaccharide standards, their mass (as measured by mass spectrometry) and their fragmentation patterns in the mass spectrometer. The concentrations of the NLO in milk have been determined using 2 different approaches: (1) by preparing a calibration curve using genuine standards of each oligosaccharide. (2) by preparing a calibration curve using maltotriose as a universal standard for all NLO, and assuming all 2AB labelled oligosaccharides give an equimolar response in the detector. The accuracy of the method was assessed by spike-recovery experiments. Using genuine NLO standards for calibration, recoveries were in the range 96-114%. Using maltotriose as a universal calibrant, recoveries were in the range 86-120%. Method precision was assessed by determining the relative standard deviation of the results under repeatability (RSD(r)) and intermediate reproducibility (RSD(iR)) conditions. In most cases RSD(r) and RSD(iR) were below 5% irrespective of calibration method, but increased when NLO levels were close to LoQ.

PMID- 29447695 TI - Cervicovaginal Microbiota and Reproductive Health: The Virtue of Simplicity. AB - Cervicovaginal microbiota play a critical role in women's health and reproductive outcomes. Despite being one of the simplest commensal bacterial communities in the human body, we are only beginning to appreciate its complex dynamic nature and important role in host immune modulation. In this review, we discuss the "optimal" cervicovaginal bacterial community composition, the impact of microbiota on gynecologic and obstetric outcomes, and the hurdles to developing a deeper mechanistic understanding of the function of the cervicovaginal microbiome. We then describe efforts to durably alter microbial composition in this compartment by promotion of Lactobacillus colonization with probiotics, modulation of vaginal pH, hormonal administration, and the eradication of pathogenic bacteria with antibiotics. Finally, we draw on lessons learned from the deeply investigated gut microbiome to suggest future avenues of research into host-pathogen interactions in the female genital tract. PMID- 29447696 TI - Strain Tracking Reveals the Determinants of Bacterial Engraftment in the Human Gut Following Fecal Microbiota Transplantation. AB - Fecal microbiota transplantation (FMT) from healthy donor to patient is a treatment for microbiome-associated diseases. Although the success of FMT requires donor bacteria to engraft in the patient's gut, the forces governing engraftment in humans are unknown. Here we use an ongoing clinical experiment, the treatment of recurrent Clostridium difficile infection, to uncover the rules of engraftment in humans. We built a statistical model that predicts which bacterial species will engraft in a given host, and developed Strain Finder, a method to infer strain genotypes and track them over time. We find that engraftment can be predicted largely from the abundance and phylogeny of bacteria in the donor and the pre-FMT patient. Furthermore, donor strains within a species engraft in an all-or-nothing manner and previously undetected strains frequently colonize patients receiving FMT. We validated these findings for metabolic syndrome, suggesting that the same principles of engraftment extend to other indications. PMID- 29447697 TI - Herpes Simplex Virus 1 VP22 Inhibits AIM2-Dependent Inflammasome Activation to Enable Efficient Viral Replication. AB - The AIM2 inflammasome is activated by DNA, leading to caspase-1 activation and release of pro-inflammatory cytokines interleukin 1beta (IL-1beta) and IL-18, which are critical mediators in host innate immune responses against various pathogens. Some viruses employ strategies to counteract inflammasome-mediated induction of pro-inflammatory cytokines, but their in vivo relevance is less well understood. Here we show that the herpes simplex virus 1 (HSV-1) tegument protein VP22 inhibits AIM2-dependent inflammasome activation. VP22 interacts with AIM2 and prevents its oligomerization, an initial step in AIM2 inflammasome activation. A mutant virus lacking VP22 (HSV-1DeltaVP22) activates AIM2 and induces IL-1beta and IL-18 secretion, but these responses are lost in the absence of AIM2. Additionally, HSV-1DeltaVP22 infection results in diminished viral yields in vivo, but HSV-1DeltaVP22 replication is largely restored in AIM2 deficient mice. Collectively, these findings reveal a mechanism of HSV-1 evasion of the host immune response that enables efficient viral replication in vivo.

PMID- 29447698 TI - Genetic Ablation of Butyrate Utilization Attenuates Gastrointestinal Salmonella Disease. AB - Salmonella enterica serovar (S.) Typhi is an extraintestinal pathogen that evolved from Salmonella serovars causing gastrointestinal disease. Compared with non-typhoidal Salmonella serovars, the genomes of typhoidal serovars contain various loss-of-function mutations. However, the contribution of these genetic differences to this shift in pathogen ecology remains unknown. We show that the ydiQRSTD operon, which is deleted in S. Typhi, enables S. Typhimurium to utilize microbiota-derived butyrate during gastrointestinal disease. Unexpectedly, genetic ablation of butyrate utilization reduces S. Typhimurium epithelial invasion and attenuates intestinal inflammation. Deletion of ydiD renders S. Typhimurium sensitive to butyrate-mediated repression of invasion gene expression. Combined with the gain of virulence-associated (Vi) capsular polysaccharide and loss of very-long O-antigen chains, two features characteristic of S. Typhi, genetic ablation of butyrate utilization abrogates S. Typhimurium-induced intestinal inflammation. Thus, the transition from a gastrointestinal to an extraintestinal pathogen involved discrete genetic changes, providing insights into pathogen evolution and emergence.

PMID- 29447731 TI - Genetics, Clinical Features, and Long-Term Outcome of Noncompaction Cardiomyopathy. AB - BACKGROUND: The clinical outcomes of noncompaction cardiomyopathy (NCCM) range from asymptomatic to heart failure, arrhythmias, and sudden cardiac death. Genetics play an important role in NCCM. OBJECTIVES: This study investigated the correlations among genetics, clinical features, and outcomes in adults and children diagnosed with NCCM. METHODS: A retrospective multicenter study from 4 cardiogenetic centers in the Netherlands classified 327 unrelated NCCM patients into 3 categories: 1) genetic, with a mutation in 32% (81 adults; 23 children) of patients; 2) probably genetic, familial cardiomyopathy without a mutation in 16% (45 adults; 8 children) of patients; or 3) sporadic, no family history, without mutation in 52% (149 adults; 21 children) of patients. Clinical features and major adverse cardiac events (MACE) during follow-up were compared across the children and adults. RESULTS: MYH7, MYBPC3, and TTN mutations were the most common mutations (71%) found in genetic NCCM. The risk of having reduced left ventricular (LV) systolic dysfunction was higher for genetic patients compared with the probably genetic and sporadic cases (p = 0.024), with the highest risk in patients with multiple mutations and TTN mutations. Mutations were more frequent in children (p = 0.04) and were associated with MACE (p = 0.025). Adults were more likely to have sporadic NCCM. High risk for cardiac events in children and adults was related to LV systolic dysfunction in mutation carriers, but not in sporadic cases. Patients with MYH7 mutations had low risk for MACE (p = 0.03). CONCLUSIONS: NCCM is a heterogeneous condition, and genetic stratification has a role in clinical care. Distinguishing genetic from nongenetic NCCM complements prediction of outcome and may lead to management and follow-up tailored to genetic status. PMID- 29447733 TI - Stroke Risk in Patients With Reduced Ejection Fraction After Myocardial Infarction Without Atrial Fibrillation. AB - BACKGROUND: Stroke can occur after myocardial infarction (MI) in the absence of atrial fibrillation (AF). OBJECTIVES: This study sought to identify risk factors (excluding AF) for the occurrence of stroke and to develop a calibrated and validated stroke risk score in patients with MI and heart failure (HF) and/or systolic dysfunction. METHODS: The datasets included in this pooling initiative were derived from 4 trials: CAPRICORN (Effect of Carvedilol on Outcome After Myocardial Infarction in Patients With Left Ventricular Dysfunction), OPTIMAAL (Optimal Trial in Myocardial Infarction With Angiotensin II Antagonist Losartan), VALIANT (Valsartan in Acute Myocardial Infarction Trial), and EPHESUS (Eplerenone Post-Acute Myocardial Infarction Heart Failure Efficacy and Survival Study); EPHESUS was used for external validation. A total of 22,904 patients without AF or oral anticoagulation were included in this analysis. The primary outcome was stroke, and death was treated as a "competing risk." RESULTS: During a median follow-up of 1.9 years (interquartile range: 1.3 to 2.7 years), 660 (2.9%) patients had a stroke. These patients were older, more often female, smokers, and hypertensive; they had a higher Killip class; a lower estimated glomerular filtration rate; and a higher proportion of MI, HF, diabetes, and stroke histories. The final stroke risk model retained older age, Killip class 3 or 4, estimated glomerular filtration rate <=45 ml/min/1.73 m2, hypertension history, and previous stroke. The models were well calibrated and showed moderate to good discrimination (C-index = 0.67). The observed 3-year event rates increased steeply for each sextile of the stroke risk score (1.8%, 2.9%, 4.1%, 5.6%, 8.3%, and 10.9%, respectively) and were in agreement with the expected event rates. CONCLUSIONS: Readily accessible risk factors associated with the occurrence of stroke were identified and incorporated in an easy-to-use risk score. This score may help in the identification of patients with MI and HF and a high risk for stroke despite their not presenting with AF. PMID- 29447734 TI - Risk Scores-Medical Derivatives. PMID- 29447736 TI - Long-Term Outcomes of Post-Operative Atrial Fibrillation: Guilty as Charged. PMID- 29447735 TI - New-Onset Atrial Fibrillation After PCI or CABG for Left Main Disease: The EXCEL Trial. AB - BACKGROUND: There is limited information on the incidence and prognostic impact of new-onset atrial fibrillation (NOAF) following percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) for left main coronary artery disease (LMCAD). OBJECTIVES: This study sought to determine the incidence of NOAF following PCI and CABG for LMCAD and its effect on 3-year cardiovascular outcomes. METHODS: In the EXCEL (Evaluation of XIENCE Versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization) trial, 1,905 patients with LMCAD and low or intermediate SYNTAX scores were randomized to PCI with everolimus-eluting stents versus CABG. Outcomes were analyzed according to the development of NOAF during the initial hospitalization following revascularization. RESULTS: Among 1,812 patients without atrial fibrillation on presentation, NOAF developed at a mean of 2.7 +/- 2.5 days after revascularization in 162 patients (8.9%), including 161 of 893 (18.0%) CABG treated patients and 1 of 919 (0.1%) PCI-treated patients (p < 0.0001). Older age, greater body mass index, and reduced left ventricular ejection fraction were independent predictors of NOAF in patients undergoing CABG. Patients with versus without NOAF had a significantly longer duration of hospitalization, were more likely to be discharged on anticoagulant therapy, and had an increased 30-day rate of Thrombolysis In Myocardial Infarction major or minor bleeding (14.2% vs. 5.5%; p < 0.0001). By multivariable analysis, NOAF after CABG was an independent predictor of 3-year stroke (6.6% vs. 2.4%; adjusted hazard ratio [HR]: 4.19; 95% confidence interval [CI]: 1.74 to 10.11; p = 0.001), death (11.4% vs. 4.3%; adjusted HR: 3.02; 95% CI: 1.60 to 5.70; p = 0.0006), and the primary composite endpoint of death, MI, or stroke (22.6% vs. 12.8%; adjusted HR: 2.13; 95% CI: 1.39 to 3.25; p = 0.0004). CONCLUSIONS: In patients with LMCAD undergoing revascularization in the EXCEL trial, NOAF was common after CABG but extremely rare after PCI. The development of NOAF was strongly associated with subsequent death and stroke in CABG-treated patients. Further studies are warranted to determine whether prophylactic strategies to prevent or treat atrial fibrillation may improve prognosis in patients with LMCAD who are undergoing CABG.

PMID- 29447738 TI - Surrogate Endpoints for Pulmonary Hypertension Management and Trial Design: Moving in the Right Direction. PMID- 29447737 TI - Pulmonary Arterial Hypertension-Related Morbidity Is Prognostic for Mortality. AB - BACKGROUND: Registry data suggest that disease progression in pulmonary arterial hypertension (PAH) is indicative of poor prognosis. However, the prognostic relevance of PAH-related morbidity has not been formally evaluated in randomized controlled trials. OBJECTIVES: The purpose of these analyses was to assess the impact of morbidity events on the risk of subsequent mortality using the landmark method and data from the SERAPHIN and GRIPHON studies. METHODS: For each study, the risk of all-cause death up to the end of the study was assessed from the landmark time point (months 3, 6, and 12) according to whether a patient had experienced a primary endpoint morbidity event before the landmark. Each analysis was conducted using data from all patients who were available for survival follow up at the landmark. RESULTS: In the SERAPHIN study, on the basis of the 3-month landmark time point, patients who experienced a morbidity event before month 3 had an increased risk of death compared with patients who did not (hazard ratio [HR]: 3.39; 95% confidence interval [CI]: 1.94 to 5.92). In the GRIPHON study, on the basis of the 3-month landmark time point, there was also an increased risk with a HR of 4.48; (95% CI: 2.98 to 6.73). Analyses based on 6-month and 12-month landmarks also showed increased risk in patients who experienced morbidity events, albeit with a reduced HR. CONCLUSIONS: These results demonstrate the prognostic relevance of PAH-related morbidity as defined in the SERAPHIN and GRIPHON studies, highlighting the importance of preventing disease progression in patients with PAH and supporting the clinical relevance of SERAPHIN and GRIPHON morbidity events.

PMID- 29447739 TI - Native T1 and ECV of Noninfarcted Myocardium and Outcome in Patients With Coronary Artery Disease. AB - BACKGROUND: Coronary artery disease (CAD) remains the major cause of cardiac morbidity and mortality worldwide, despite the advances in treatment with coronary revascularization and modern antiremodeling therapy. Risk stratification in CAD patients is primarily based on left ventricular volumes, ejection fraction (LVEF), risk scores, and the presence and extent of late gadolinium enhancement (LGE). The prognostic role of T1 mapping in noninfarcted myocardium in CAD patients has not yet been determined. OBJECTIVES: This study sought to examine prognostic significance of native T1 mapping of noninfarcted myocardium in patients with CAD. METHODS: A prospective, observational, multicenter longitudinal study of consecutive patients undergoing routine cardiac magnetic resonance imaging with T1 mapping and LGE. The primary endpoint was all-cause mortality. Major adverse cardiocerebrovascular events (MACCE) (cardiac mortality, nonfatal acute coronary syndrome, stroke, and appropriate device discharge) are also reported. RESULTS: A total of 34 deaths and 71 MACCE (n = 665, males n = 424, median age [interquartile range] 57 [22] years; 64%; median follow-up period of 17 [11] months) were observed. Native T1 and extracellular volume were univariate predictors of outcome. Native T1 and LGE were stronger predictors of survival and MACCE compared with extracellular volume, LVEF, cardiac volumes, and clinical scores (p < 0.001). Native T1 of noninfarcted myocardium was the sole independent predictor of all-cause mortality (chi-square = 21.7; p < 0.001), which was accentuated in the absence of LGE or LVEF <=35%. For MACCE, native T1 and LGE extent were joint independent predictors (chi-square = 25.6; p < 0.001). CONCLUSIONS: Characterization of noninfarcted myocardium by native T1 is an important predictor of outcome in CAD patients, over and above the traditional risk stratifiers. The current study's results provide a basis for a novel risk stratification model in CAD based on a complementary assessment of noninfarcted myocardium and post-infarction scar, by native T1 mapping and LGE, respectively. PMID- 29447741 TI - The Burden of Iron Deficiency in Heart Failure: Therapeutic Approach. AB - Heart failure (HF) is highlighted by its burdening symptom-limited exercise capacity and recurrent hospitalizations. Despite substantial advances regarding disease-modifying drugs in HF with reduced ejection fraction, additional therapeutic strategies to improve quality of life are invaluable. Currently, iron deficiency (ID) is overwhelmingly recognized in over 30% to 50% of patients with stable chronic HF, which worsens prognosis. The established pathophysiological mechanisms of progressive HF may be intertwined with increasing myocardial iron scarcity, wherein one begets the other. Most importantly, ID constitutes a novel target for symptom relief in carefully selected patients. In this regard, intravenous iron may be a safe and efficacious intervention, potentially reducing HF hospitalizations. We discuss the evidence and gaps in knowledge concerning iron therapy in HF and propose a practical, comprehensive, clinically oriented algorithm for timely adequate iron replenishment in different clinical scenarios. Finally, we further debate imperative decision-making before intervention and the drawbacks of such a strategy. PMID- 29447742 TI - A Comparative Analysis of Current Lipid Treatment Guidelines: Nothing Stands Still. AB - Lipid treatment guidelines have continued to evolve as new evidence emerges. We sought to review similarities and differences of 5 lipid treatment guidelines from the American College of Cardiology/American Heart Association, Canadian Cardiovascular Society, European Society for Cardiology/European Atherosclerosis Society, U.S. Preventive Services Task Force, and U.S. Veterans Affairs/Department of Defense. All guidelines utilize rigorous evidentiary review, highlight statin therapy for primary and secondary prevention of atherosclerotic cardiovascular disease, and emphasize a clinician-patient risk discussion. However, there are differences in statin intensities, use of risk estimators, treatment of specific patient subgroups, and consideration of safety concerns. Clinicians should understand these similarities and differences in current and future guideline recommendations when considering if and how to treat their patients with statin therapy.

PMID- 29447753 TI - Kinematics of the anthropoid os centrale and the functional consequences of scaphoid-centrale fusion in African apes and hominins. AB - In most primates, the os centrale is interposed between the scaphoid, trapezoid, trapezium, and head of the capitate, thus constituting a component of the wrist's midcarpal complex. Scaphoid-centrale fusion is among the clearest morphological synapomorphies of African apes and hominins. Although it might facilitate knuckle walking by increasing the rigidity and stability of the radial side of the wrist, the exact functional significance of scaphoid-centrale fusion is unclear. If fusion acts to produce a more rigid radial wrist that stabilizes the hand and limits shearing stresses, then in taxa with a free centrale, it should anchor ligaments that check extension and radial deviation, but exhibit motion independent of the scaphoid. Moreover, because the centrale sits between the scaphoid and capitate (a major stabilizing articulation), scaphoid-centrale mobility should correlate with scaphocapitate mobility in extension and radial deviation. To test these hypotheses, the centrale's ligamentous binding was investigated via dissection in Pongo and Papio, and the kinematics of the centrale were quantified in a cadaveric sample of anthropoids (Pongo sp., Ateles geoffroyi, Colobus guereza, Macaca mulatta, and Papio anubis) using a computed tomography-based method to track wrist-bone motion. Results indicate that the centrale rotates freely relative to the scaphoid in all taxa. However, centrale mobility is only correlated with scaphocapitate mobility during extension in Pongo-possibly due to differences in overall wrist configuration between apes and monkeys. If an extant ape-like wrist characterized early ancestors of African apes and hominins, then scaphoid-centrale fusion would have increased midcarpal rigidity in extension relative to the primitive condition. Although biomechanically consistent with a knuckle-walking hominin ancestor, this assumes that the trait evolved specifically for that biological role, which must be squared with contradictory interpretations of extant and fossil hominoid morphology. Regardless of its original adaptive significance, scaphoid-centrale fusion likely presented a constraint on early hominin midcarpal mobility. PMID- 29447754 TI - Strontium isotopic aspects of Paranthropus robustus teeth; implications for habitat, residence, and growth. AB - The strontium isotopic ratio 87Sr/86Sr has been studied in the Sterkfontein Valley of South Africa to infer both habitat usage and residence for a number of early hominins. This paper examines the existing 87Sr/86Sr data collectively derived from three studies of Paranthropus robustus teeth with the aim of exploring whether the dataset as a whole may provide deeper insight into habitat, mobility, and growth for this species. 87Sr/86Sr from seven Swartkrans Member I third molars varies in a well defined narrow range, and while some canines were consistent with this range, a number of P. robustus canines and first and second molars were not, and therefore represent individuals who had arrived from other localities. A first and third molar 87Sr/86Sr was found to differ in TM1517c, the holotype P. robustus specimen from Kromdraai, suggesting this individual had moved to the locality sometime after the first molar and before the third molar had completely mineralized. While early forming teeth vary widely, the relatively low variation and absence of exogenous 87Sr/86Sr in third molars suggest that these teeth mineralized relatively late when compared to life history events bearing on higher primate residence patterns. The implications for further study of habitat, residence, and growth are discussed. PMID- 29447755 TI - Maturation is prolonged and variable in female chimpanzees. AB - Chimpanzees are important referential models for the study of life history in hominin evolution. Age at sexual maturity and first reproduction are key life history milestones that mark the diversion of energy from growth to reproduction and are essential in comparing life history trajectories between chimpanzees and humans. Yet, accurate information on ages at these milestones in wild chimpanzees is difficult to obtain because most females transfer before breeding. Precise age at first birth is only known from a relatively small number of non-dispersing individuals. Moreover, due to small sample sizes, the degree to which age at maturation milestones varies is unknown. Here we report maturation milestones and explore sources of variance for 36 wild female chimpanzees of known age, including eight dispersing females born in Gombe National Park, Tanzania. Using Kaplan-Meier survival analysis, including censored intervals, we find an average age of 11.5 years (range 8.5-13.9) at sexual maturity and 14.9 years (range 11.1 22.1) at first birth. These values exceed previously published averages for wild chimpanzees by one or more years. Even in this larger sample, age at first birth is likely underestimated due to the disproportionate number of non-dispersing females, which, on average, give birth two years earlier than dispersing females. Model selection using Cox Proportional Hazards models shows that age at sexual maturity is delayed in females orphaned before age eight years and those born to low-ranking mothers. Age at first birth is most delayed in dispersing females and those orphaned before age eight years. These data provide improved estimates of maturation milestones in a population of wild female chimpanzees and indicate the importance of maternal factors in development. PMID- 29447756 TI - The biomechanical significance of the frontal sinus in Kabwe 1 (Homo heidelbergensis). AB - Paranasal sinuses are highly variable among living and fossil hominins and their function(s) are poorly understood. It has been argued they serve no particular function and are biological 'spandrels' arising as a structural consequence of changes in associated bones and/or soft tissue structures. In contrast, others have suggested that sinuses have one or more functions, in olfaction, respiration, thermoregulation, nitric oxide production, voice resonance, reduction of skull weight, and craniofacial biomechanics. Here we assess the extent to which the very large frontal sinus of Kabwe 1 impacts on the mechanical performance of the craniofacial skeleton during biting. It may be that the browridge is large and the sinus has large trabecular struts traversing it to compensate for the effect of a large sinus on the ability of the face to resist forces arising from biting. Alternatively, the large sinus may have no impact and be sited where strains that arise from biting would be very low. If the former is true, then infilling of the sinus would be expected to increase the ability of the skeleton to resist biting loads, while removing the struts might have the opposite effect. To these ends, finite element models with hollowed and infilled variants of the original sinus were created and loaded to simulate different bites. The deformations arising due to loading were then compared among different models and bites by contrasting the strain vectors arising during identical biting tasks. It was found that the frontal bone experiences very low strains and that infilling or hollowing of the sinus has little effect on strains over the cranial surface, with small effects over the frontal bone. The material used to infill the sinus experienced very low strains. This is consistent with the idea that frontal sinus morphogenesis is influenced by the strain field experienced by this region such that it comes to lie entirely within a region of the cranium that would otherwise experience low strains. This has implications for understanding why sinuses vary among hominin fossils. PMID- 29447757 TI - Using the covariation of extant hominoid upper and lower jaws to predict dental arcades of extinct hominins. AB - Upper and lower jaws are well represented in the fossil record of mammals and are frequently used to diagnose species. Some hominin species are only known by either their maxillary or mandibular morphology, and in this study, we explore the possibility of predicting their complementary dental arcade shape to aid the recognition of conspecific specimens in the fossil record. To this end, we apply multiple multivariate regression to analyze 3D landmark coordinates collected on associated upper and lower dental arcades of extant Homo, Pan, Gorilla, Pongo, and Hylobates. We first study the extant patterns of variation in dental arcade shape and quantify how accurate predictions of complementary arcades are. Then we explore applications of this extant framework for interpreting the fossil record based on two fossil hominin specimens with associated upper and lower jaws, KNM WT 15000 (Homo erectus sensu lato) and Sts 52 (Australopithecus africanus), as well as two non-associated specimens of Paranthropus boisei, the maxilla of OH 5 and the Peninj mandible. We find that the shape differences between the predictions and the original fossil specimens are in the range of variation within genera or species and therefore are consistent with their known affinity. Our approach can provide a reference against which intraspecific variation of extinct species can be assessed. We show that our method predicts arcade shapes reliably even if the target shape is not represented in the reference sample. We find that in extant hominoids, the amount of within-taxon variation in dental arcade shape often overlaps with the amount of between-taxon shape variation. This implies that whereas a large difference in dental arcade shape between two individuals typically suggests that they belong to different species or even genera, a small shape difference does not necessarily imply conspecificity. PMID- 29447758 TI - Nasolacrimal anatomy and haplorhine origins. AB - Computed tomography X-ray imaging of the internal face in well-preserved primate fossil crania permits reconstruction of the nature of their nasal anatomy, including some soft-tissue features. These features are diagnostic of the primate suborder Haplorhini, and allow reevaluation of the phylogenetic status of several purported early members of the group. Here we examine the nasolacrimal morphology of a broad sample of extant primates, as well as a number of Paleogene fossils. The extant sample confirms the distinctiveness of the two suborders. Of the fossils studied, only Shoshonius cooperi from the late-early Eocene exhibits evidence of a haplorhine nose. This suggests that the haplorhine oronasal complex may have evolved before the postorbital septum, and strengthens the claim that Shoshonius is a close relative of tarsiers and anthropoids. These results indicate that Omomyiformes is not a monophyletic group, and that few of its members possessed the derived oronasal morphology that characterizes crown haplorhines. PMID- 29447759 TI - Ecomorphological analysis of bovid mandibles from Laetoli Tanzania using 3D geometric morphometrics: Implications for hominin paleoenvironmental reconstruction. AB - The current study describes a new method of mandibular ecological morphology (ecomorphology). Three-dimensional geometric morphometrics (3D GM) was used to quantify mandibular shape variation between extant bovids with different feeding preferences. Landmark data were subjected to generalized Procrustes analysis (GPA), principal components analysis (PCA), and discriminant function analysis (DFA). The PCA resulted in a continuum from grazers to browsers along PC1 and DFA classified 88% or more of the modern specimens to the correct feeding category. The protocol was reduced to a subset of landmarks on the mandibular corpus in order to make it applicable to incomplete fossils. The reduced landmark set resulted in greater overlap between feeding categories but maintained the same continuum as the complete landmark model. The DFA resubstitution and jackknife analyses resulted in classification success rates of 85% and 80%, respectively. The reduced landmark model was applied to fossil mandibles from the Upper Laetolil Beds (~4.3-3.5 Ma) and Upper Ndolanya Beds (~2.7-2.6 Ma) at Laetoli, Tanzania in order to assess antelope diet, and indirectly evaluate paleo vegetation structure. The majority of the fossils were classified by the DFA as browsers or mixed feeders preferring browse. Our results indicate a continuous presence of wooded habitats and are congruent with recent environmental studies at Laetoli indicating a mosaic woodland-bushland-grassland savanna ecosystem. PMID- 29447760 TI - Climatic controls on Later Stone Age human adaptation in Africa's southern Cape. AB - Africa's southern Cape is a key region for the evolution of our species, with early symbolic systems, marine faunal exploitation, and episodic production of microlithic stone tools taken as evidence for the appearance of distinctively complex human behavior. However, the temporally discontinuous nature of this evidence precludes ready assumptions of intrinsic adaptive benefit, and has encouraged diverse explanations for the occurrence of these behaviors, in terms of regional demographic, social and ecological conditions. Here, we present a new high-resolution multi-proxy record of environmental change that indicates that faunal exploitation patterns and lithic technologies track climatic variation across the last 22,300 years in the southern Cape. Conditions during the Last Glacial Maximum and deglaciation were humid, and zooarchaeological data indicate high foraging returns. By contrast, the Holocene is characterized by much drier conditions and a degraded resource base. Critically, we demonstrate that systems for technological delivery - or provisioning - were responsive to changing humidity and environmental productivity. However, in contrast to prevailing models, bladelet-rich microlithic technologies were deployed under conditions of high foraging returns and abandoned in response to increased aridity and less productive subsistence environments. This suggests that posited links between microlithic technologies and subsistence risk are not universal, and the behavioral sophistication of human populations is reflected in their adaptive flexibility rather than in the use of specific technological systems. PMID- 29447761 TI - New Neandertal wrist bones from El Sidron, Spain (1994-2009). AB - Twenty-nine carpal bones of Homo neanderthalensis have been recovered from the site of El Sidron (Asturias, Spain) during excavations between 1994 and 2009, alongside ~2500 other Neandertal skeletal elements dated to ~49,000 years ago. All bones of the wrist are represented, including adult scaphoids (n = 6), lunates (n = 2), triquetra (n = 4), pisiforms (n = 2), trapezia (n = 2), trapezoids (n = 5), capitates (n = 5), and hamates (n = 2), as well as one fragmentary and possibly juvenile scaphoid. Several of these carpals appear to belong to the complete right wrist of a single individual. Here we provide qualitative and quantitative morphological descriptions of these carpals, within a comparative context of other European and Near Eastern Neandertals, early and recent Homo sapiens, and other fossil hominins, including Homo antecessor, Homo naledi, and australopiths. Overall, the El Sidron carpals show characteristics that typically distinguish Neandertals from H. sapiens, such as a relatively flat first metacarpal facet on the trapezium and a more laterally oriented second metacarpal facet on the capitate. However, there are some distinctive features of the El Sidron carpals compared with most other Neandertals. For example, the tubercle of the trapezium is small with limited projection, while the scaphoid tubercle and hamate hamulus are among the largest seen in other Neandertals. Furthermore, three of the six adult scaphoids show a distinctive os-centrale portion, while another is a bipartite scaphoid with a truncated tubercle. The high frequency of rare carpal morphologies supports other evidence of a close genetic relationship among the Neandertals found at El Sidron. PMID- 29447762 TI - The easternmost Middle Paleolithic (Mousterian) from Jinsitai Cave, North China. AB - The dispersal of Neanderthals and their genetic and cultural interactions with anatomically modern humans and other hominin populations in Eurasia are critical issues in human evolution research. Neither Neanderthal fossils nor typical Mousterian assemblages have been reported in East Asia to date. Here we report on artifact assemblages comparable to western Eurasian Middle Paleolithic (Mousterian) at Jinsitai, a cave site in North China. The lithic industry at Jinsitai appeared at least 47-42 ka and persisted until around 40-37 ka. These findings expand the geographic range of the Mousterian-like industries at least 2000 km further to the east than what has been previously recognized. This discovery supplies a missing part of the picture of Middle Paleolithic distribution in Eurasia and also demonstrates the makers' capacity to adapt to diverse geographic regions and habitats of Eurasia. PMID- 29447763 TI - Scaling of bony canals for encephalic vessels in euarchontans: Implications for the role of the vertebral artery and brain metabolism. AB - Supplying the central nervous system with oxygen and glucose for metabolic activities is a critical function for all animals at physiologic, anatomical, and behavioral levels. A relatively proximate challenge to nourishing the brain is maintaining adequate blood flow. Euarchontans (primates, dermopterans and treeshrews) display a diversity of solutions to this challenge. Although the vertebral artery is a major encephalic vessel, previous research has questioned its importance for irrigating the cerebrum. This presents a puzzling scenario for certain strepsirrhine primates (non-cheirogaleid lemuriforms) that have reduced promontorial branches of the internal carotid artery and no apparent alternative encephalic vascular route except for the vertebral artery. Here, we present results of phylogenetic comparative analyses of data on the cross-sectional area of bony canals that transmit the vertebral artery (transverse foramina). These results show that, across primates (and within major primate subgroups), variation in the transverse foramina helps significantly to explain variation in forebrain mass even when variation in promontorial canal cross-sectional areas are also considered. Furthermore, non-cheirogaleid lemuriforms have larger transverse foramina for their endocranial volume than other euarchontans, suggesting that the vertebral arteries compensate for reduced promontorial artery size. We also find that, among internal carotid-reliant euarchontans, species that are more encephalized tend to have a promontorial canal that is larger relative to the transverse foramina. Tentatively, we consider the correlation between arterial canal diameters (as a proxy for blood flow) and brain metabolic demands. The results of this analysis imply that human investment in brain metabolism (~27% of basal metabolic rate) may not be exceptional among euarchontans.

PMID- 29447769 TI - Apixaban following acute coronary syndromes in patients with prior stroke: Insights from the APPRAISE-2 trial. AB - BACKGROUND AND PURPOSE: Patients with prior stroke are at greater risk for recurrent cardiovascular events post-acute coronary syndromes (ACS) and may have a different risk/benefit profile with antithrombotic therapy than patients without prior stroke. METHODS: We studied 7391 patients with ACS from APPRAISE-2, stratified by the presence or absence of prior stroke. Baseline characteristics and outcomes of cardiovascular death, myocardial infarction (MI), or stroke were compared between groups. Interactions between prior stroke, treatment assignment (apixaban vs placebo), and outcomes were tested before and after multivariable adjustment with Cox proportional hazards models. RESULTS: A total of 902 patients (12%) had prior stroke. Those with prior stroke were older (69 vs 67 years), had more hypertension (91% vs 77%), peripheral vascular disease (22% vs18%), and impaired renal function (38% vs 30%) but less diabetes (44% vs 48%) than those without prior stroke. Patients with prior stroke vs no prior stroke had higher unadjusted rates of cardiovascular death (4.8% vs 4.0%), MI (11.2% vs 7.1%), and ischemic stroke (3.2% vs 0.9%). Patients with prior stroke assigned to apixaban had similar rates of the composite of cardiovascular death, MI, or stroke compared with those assigned to placebo (HR 1.39; 95% CI 0.92-2.08). Patients without prior stroke assigned to apixaban had similar rates of cardiovascular death, MI, or ischemic stroke compared with those assigned to placebo (HR 0.87; 95% CI 0.73-1.04; P-interaction=.041). Median follow-up was 240 days. CONCLUSIONS: Patients with prior stroke are at higher risk for recurrent cardiovascular events post-ACS and had a differential risk/benefit profile with oral anticoagulation. PMID- 29447770 TI - Efficacy and safety of dual antiplatelet therapy after coronary stenting in patients with chronic kidney disease. AB - BACKGROUND: We compared efficacy and safety of short- (3 or 6 months) versus long term (>=12 months) dual antiplatelet therapy (DAPT) after drug-eluting stent (DES) implantation, according to the presence of chronic kidney disease (CKD). METHODS: Patient-level pooled analysis was performed with 7242 patients (87.2% with 2nd generation DES) from 5 randomized controlled trials. RESULTS: In both CKD (1273 patients) and non-CKD (5969 patients) population, the rates of patient oriented composite outcomes at 1-year (POCO, all-cause death, any myocardial infarction [MI], stroke and TIMI major bleeding) were not different between the short- and long-term DAPT (hazard ratio [HR] 1.19, 95% confidence interval [CI] 0.76-1.86, P=.449 in CKD population; HR 1.14, 95% CI 0.83-1.56, P=.434 in non-CKD population). The rates of coronary thrombotic events (any MI and definite/probable stent thrombosis) also did not differ between short- and long term DAPT in either CKD or non-CKD population. As for bleeding events, long-term DAPT increased the TIMI major bleeding (HR 2.91, 95% CI 1.31-6.48, P=.009) in non CKD population. The similar trend was observed with long-term DAPT in CKD population. But it did not reach statistical significance (HR 3.15, 95% CI 0.64 15.63, P=.160). CONCLUSIONS: The rates of POCO and coronary thrombotic events were significantly higher in patients with CKD compared with those without CKD, which were not affected by short- or long-term DAPT. Higher bleeding incidence by long-term DAPT was only observed in non-CKD patients but not in CKD patients. Further large scale studies are warranted to confirm our findings. PMID- 29447771 TI - Topographical distribution of perioperative cerebral infarction associated with transcatheter aortic valve implantation. AB - BACKGROUND: Transcatheter aortic valve implantation (TAVI) is associated with a high incidence of cerebrovascular injury. As these injuries are thought to be primarily embolic, neuroprotection strategies have focused on embolic protection devices. However, the topographical distribution of cerebral emboli and how this impacts on the effectiveness of these devices have not been thoroughly assessed. Here, we evaluated the anatomical characteristics of magnetic resonance imaging (MRI)-defined cerebral ischemic lesions occurring secondary to TAVI to enhance our understanding of the distribution of cardioembolic phenomena. METHODS: Forty patients undergoing transfemoral TAVI with an Edwards SAPIEN-XT valve under general anesthesia were enrolled prospectively in this observational study. Participants underwent brain MRI preprocedure, and 3 +/- 1 days and 6 +/- 1 months postprocedure. RESULTS: Mean +/- SD participant age was 82 +/- 7 years. Patients had an intermediate to high surgical risk, with a mean Society of Thoracic Surgeons score of 6.3 +/- 3.5 and EuroSCORE of 18.1 +/- 10.6. Post-TAVI, there were no clinically apparent cerebrovascular events, but MRI assessments identified 83 new lesions across 19 of 31 (61%) participants, with a median +/- interquartile range number and volume of 1 +/- 2.8 lesions and 20 +/- 190 MUL per patient. By volume, 80% of the infarcts were cortical, 90% in the posterior circulation and 81% in the right hemisphere. CONCLUSIONS: The distribution of lesions that we detected suggests that cortical gray matter, the posterior circulation, and the right hemisphere are all particularly vulnerable to perioperative cerebrovascular injury. This finding has implications for the use of intraoperative cerebral embolic protection devices, particularly those that leave the left subclavian and, therefore, left vertebral artery unprotected. PMID- 29447772 TI - The Optimal Anti-Coagulation for Enhanced-Risk Patients Post-Catheter Ablation for Atrial Fibrillation (OCEAN) trial. AB - BACKGROUND: The optimal long-term antithrombotic regimen for patients after successful catheter-based atrial fibrillation (AF) ablation is not well defined. Presently, practice variation exists, and the benefits of oral anticoagulation over antiplatelet therapy across the entire spectrum of stroke risk profile remain undefined in the postablation population. To date, there are no randomized trials to inform clinicians on this therapeutic question. OBJECTIVE: The objective was to assess whether rivaroxaban is superior to acetylsalicylic acid (ASA) in reducing the risk of clinically overt stroke, systemic embolism, or covert stroke among patients without apparent recurrent atrial arrhythmias for at least 1 year after their most recent AF ablation procedure. METHODS/DESIGN: A prospective, multicenter, open-label, randomized trial with blinded assessment of outcomes is under way (NCT02168829). Atrial fibrillation patients with at least 1 stroke risk factor (as defined by the CHA2DS2-VASc score) and without known atrial arrhythmia recurrences for at least 12 months after ablation are randomized to rivaroxaban 15 mg or ASA 75-160 mg daily. The primary outcome is a composite of clinically overt stroke, systemic embolism, and covert stroke based on brain magnetic resonance imaging. Key secondary outcomes include major bleeding outcomes, intracranial hemorrhage, transient ischemic attack, neuropsychological testing, quality of life, and an economic analysis. Subjects will be followed for 3 years. The estimated overall sample size is 1,572 subjects (786 per arm). DISCUSSION: The OCEAN trial is a multicenter randomized controlled trial evaluating 2 antithrombotic treatment strategies for patients with risk factors for stroke after apparently successful AF ablation. We hypothesize that rivaroxaban will reduce the occurrence of clinically overt stroke, systemic embolism, and covert stroke when compared with ASA alone. PMID- 29447773 TI - Percutaneous coronary intervention and antiplatelet therapy in patients with atrial fibrillation receiving apixaban or warfarin: Insights from the ARISTOTLE trial. AB - BACKGROUND: We assessed antiplatelet therapy use and outcomes in patients undergoing percutaneous coronary intervention (PCI) during the ARISTOTLE trial. METHODS: Patients were categorized based on the occurrence of PCI during follow up (median 1.8 years); PCI details and outcomes post-PCI are reported. Of the 18,201 trial participants, 316 (1.7%) underwent PCI (152 in apixaban group, 164 in warfarin group). RESULTS: At the time of PCI, 84% (267) were on study drug (either apixaban or warfarin). Of these, 19% did not stop study drug during PCI, 49% stopped and restarted <5 days post-PCI, and 30% stopped and restarted >5 days post-PCI. At 30 days post-PCI, 35% of patients received dual -antiplatelet therapy (DAPT), 23% received aspirin only, and 13% received a P2Y12 inhibitor only; 29% received no antiplatelet therapy. Triple therapy (DAPT + oral anticoagulant [OAC]) was used in 21% of patients, 23% received OAC only, 15% received OAC plus aspirin, and 9% received OAC plus a P2Y12 inhibitor; 32% received antiplatelet agents without OAC. Post-PCI, patients assigned to apixaban versus warfarin had numerically similar rates of major bleeding (5.93 vs 6.73 events/100 patient-years; P = .95) and stroke (2.74 vs 1.84 events/100 patient years; P = .62). CONCLUSIONS: PCI occurred infrequently during follow-up. Most patients on study drug at the time of PCI remained on study drug in the peri-PCI period; 19% continued the study drug without interruption. Antiplatelet therapy use post-PCI was variable, although most patients received DAPT. Additional data are needed to guide the use of antithrombotics in patients undergoing PCI. PMID- 29447774 TI - Percutaneous coronary intervention of lesions with in-stent restenosis: A report from the ADAPT-DES study. AB - BACKGROUND: There is a paucity of data from large contemporary cohorts of patients with in-stent restenosis (ISR) treated with drug-eluting stents (DESs), and no studies have examined the impact of high platelet reactivity (HPR) on the occurrence of ischemic events after ISR percutaneous coronary intervention (PCI) with DESs. We sought to report outcomes after PCI of ISR lesions and its association with HPR. METHODS: Patients in the prospective, multicenter ADAPT-DES study were stratified according to whether they had ISR versus non-ISR PCI. Two year outcomes were compared between the groups using Cox proportional hazards models. HPR was defined as on-clopidogrel P2Y12 platelet reaction units >208 as measured by the VerifyNow assay; target vessel failure (TVF) was defined as the composite of all-cause death, myocardial infarction, or ischemia-driven target vessel revascularization. RESULTS: Among the 8,582 patients included in the ADAPT DES study, 840 (9.8%) patients underwent successful ISR PCI. ISR PCI was independently associated with a higher 2-year risk of TVF (adjusted hazard ratio [HR] 1.95; 95% CI 1.68-2.27; P<.001) and stent thrombosis (adjusted HR 1.95; 95% CI 1.08-3.51; P=.027) but not bleeding (adjusted HR 0.94; 95% CI 0.73-1.21; P=.64). There was no statistical interaction between HPR and ISR versus non-ISR PCI in regard to TVF (adjusted Pinteraction=.81). CONCLUSIONS: ISR PCI is associated with a considerably higher risk of 2-year adverse ischemic events, with HPR conferring similar risk in ISR and non-ISR PCI. More effective therapeutic strategies for managing ISR lesions are necessary.

PMID- 29447777 TI - Cognition and brain changes associated with high-dose atorvastatin: A BOLD proposition? PMID- 29447776 TI - The relative benefits of claims and electronic health record data for predicting medication adherence trajectory. AB - BACKGROUND: Healthcare providers are increasingly encouraged to improve their patients' adherence to chronic disease medications. Prediction of adherence can identify patients in need of intervention, but most prediction efforts have focused on claims data, which may be unavailable to providers. Electronic health records (EHR) are readily available and may provide richer information with which to predict adherence than is currently available through claims. METHODS: In a linked database of complete Medicare Advantage claims and comprehensive EHR from a multi-specialty outpatient practice, we identified patients who filled a prescription for a statin, antihypertensive, or oral antidiabetic during 2011 to 2012. We followed patients to identify subsequent medication filling patterns and used group-based trajectory models to assign patients to adherence trajectories. We then identified potential predictors from both claims and EHR data and fit a series of models to evaluate the accuracy of each data source in predicting medication adherence. RESULTS: Claims were highly predictive of patients in the worst adherence trajectory (C=0.78), but EHR data also provided good predictions (C=0.72). Among claims predictors, presence of a prior gap in filling of at least 6 days was by far the most influential predictor. In contrast, good predictions from EHR data required complex models with many variables. CONCLUSION: EHR data can provide good predictions of adherence trajectory and therefore may be useful for providers seeking to deploy resource-intensive interventions. However, prior adherence information derived from claims is most predictive, and can supplement EHR data when it is available. PMID- 29447779 TI - Changes in lipoprotein(a) following bariatric surgery. PMID- 29447778 TI - The effect of high-dose atorvastatin on neural activity and cognitive function. AB - BACKGROUND: Functional magnetic resonance imaging (fMRI) has not been used to assess the effects of statins on the brain. We assessed the effect of statins on cognition using standard neuropsychological assessments and brain neural activation with fMRI on two tasks. METHODS: Healthy statin-naive men and women (48+/-15 years) were randomized to 80 mg/day atorvastatin (n=66; 27 men) or placebo (n=84; 48 men) for 6 months. Participants completed cognitive testing while on study drug and 2 months after treatment cessation using alternative test and task versions. RESULTS: There were few changes in standard neuropsychological tests with drug treatment (all P>.56). Total and delayed recall from the Hopkins Verbal Learning Test-Revised increased in both groups (P<.05). The Stroop Color Word score increased (P<.01) and the 18-Point Clock Test decreased in the placebo group (P=.02) after drug cessation. There were, however, small but significant group-time interactions for each fMRI task: participants on placebo had greater activation in the right putamen/dorsal striatum during the maintenance phase of the Sternberg task while on placebo but the effect was reversed after drug washout (P<.001). Participants on atorvastatin had greater activation in the bilateral precuneus during the encoding phase of the Figural Memory task while on drug but the effect was reversed after drug washout (P<.001). CONCLUSION: Six months of high dose atorvastatin therapy is not associated with measurable changes in neuropsychological test scores, but did evoke transient differences in brain activation patterns. Larger, longer-term clinical trials are necessary to confirm these findings and evaluate their clinical implications. PMID- 29447780 TI - Nonprimary PCI at hospitals without cardiac surgery on-site: Consistent outcomes for all? AB - BACKGROUND: The CPORT-E trial showed the noninferiority of nonprimary percutaneous coronary intervention (PCI) at hospitals without cardiac surgery on site (SoS) compared with hospitals with SoS for 6-week mortality and 9-month major adverse cardiac events (MACE). However, target vessel revascularization (TVR) was increased at non-SoS hospitals. Therefore, we aimed to determine the consistency of the CPORT-E trial findings across the spectrum of enrolled patients. METHODS: Post hoc subgroup analyses of 6-week mortality and 9-month MACE, defined as the composite of death, Q-wave myocardial infarction, or TVR, were performed. Patients with and without 9-month TVR and rates of related outcomes were compared. RESULTS: There was no interaction between SoS status and clinically relevant subgroups for 6-week mortality or 9-month MACE (P for any interaction=.421 and .062, respectively). In addition to increased 9-month rates of TVR and diagnostic catheterization at hospitals without SoS, non-TVR was also increased (2.7% vs 1.9%, P=.002); there was no difference in myocardial infarction-driven TVR, non-TVR, or diagnostic catheterization. Predictors of 9 month TVR included intra-aortic balloon pump use, any index PCI complication, and 3-vessel PCI, whereas predictors of freedom from TVR included SoS, discharge on a P2Y12 inhibitor, and stent implantation. CONCLUSIONS: The noninferiority of nonprimary PCI at non-SoS hospitals was consistent across clinically relevant subgroups. Elective PCI at an SoS hospital conferred a TVR benefit which may be related to a lower rate of referral for diagnostic catheterization for reasons other than myocardial infarction. PMID- 29447781 TI - Prediction of long-term net clinical outcomes using the TIMI-AF score: Comparison with CHA2DS2-VASc and HAS-BLED. AB - : The TIMI-AF score was described to predict net clinical outcomes (NCOs) in atrial fibrillation (AF) patients receiving warfarin. However, this score derived from the ENGAGE AF-TIMI 48 trial, and no external validation exists in real world clinical practice. We tested the long-term predictive performance of the TIMI-AF score in comparison with CHA2DS2-VASc and HAS-BLED in a 'real-world' cohort of anticoagulated AF patients. METHODS: We included 1156 consecutive AF patients stable on vitamin K antagonist (INR 2.0-3.0) during 6 months. The baseline risk of NCOs (composite of stroke, life-threatening bleeding, or all-cause mortality) was calculated using the novel TIMI-AF score. During follow-up, all NCOs were recorded and the predictive performance and clinical usefulness of TIMI-AF was compared with CHA2DS2-VASc and HAS-BLED. RESULTS: During 6.5 years (IQR 4.3-7.9), there were 563 NCOs (7.49%/year). 'Low-risk' (6.07%/year) and 'medium-risk' (9.49%/year) patients defined by the TIMI-AF suffered more endpoints that low- and medium-risk patients of CHA2DS2-VASc and HAS-BLED (2.37%/year and 4.40%/year for low risk; 3.48%/year and 6.39%/year for medium risk, respectively). The predictive performance of TIMI-AF was not different from CHA2DS2-VASc (0.678 vs 0.677, P = .963) or HAS-BLED (0.644 vs 0.671, P = .054). Discrimination and reclassification did not show improvement of prediction using the TIMI-AF score, and decision curves analysis did not demonstrate higher net benefit. CONCLUSIONS: In VKA-experienced AF patients, the TIMI-AF score has limited usefulness predicting NCOs over a long-term period of follow-up. This novel score was not superior to CHA2DS2-VASc and HAS-BLED identifying low-risk AF patients. PMID- 29447782 TI - Comparison of drug-eluting stents and drug-coated balloon for the treatment of drug-eluting coronary stent restenosis: A randomized RESTORE trial. AB - BACKGROUND: This study sought to evaluate the optimal treatment for in-stent restenosis (ISR) of drug-eluting stents (DESs). METHODS: This is a prospective, multicenter, open-label, randomized study comparing the use of drug-eluting balloon (DEB) versus second-generation everolimus-eluting stent for the treatment of DES ISR. The primary end point was in-segment late loss at 9-month routine angiographic follow-up. RESULTS: A total of 172 patients were enrolled, and 74 (43.0%) patients underwent the angiographic follow-up. The primary end point was not different between the 2 treatment groups (DEB group 0.15+/-0.49 mm vs DES group 0.19+/-0.41 mm, P=.54). The secondary end points of in-segment minimal luminal diameter (MLD) (1.80+/-0.69 mm vs 2.09+/-0.46 mm, P=.03), in-stent MLD (1.90+/-0.71 mm vs 2.29+/-0.48 mm, P=.005), in-segment percent diameter stenosis (34%+/-21% vs 26%+/-15%, P=.05), and in-stent percent diameter stenosis (33%+/ 21% vs 21%+/-15%, P=.002) were more favorable in the DES group. The composite of death, myocardial infarction, or target lesion revascularization at 1 year was comparable between the 2 groups (DEB group 7.0% vs DES group 4.7%, P=.51). CONCLUSIONS: Treatment of DES ISR using DEB or second-generation DES did not differ in terms of late loss at 9-month angiographic follow-up, whereas DES showed better angiographic results regarding minimal MLD and percent diameter stenosis. Both treatment strategies were safe and effective up to 1year after the procedure. PMID- 29447783 TI - Representation of black patients in randomized clinical trials of heart failure with reduced ejection fraction. AB - BACKGROUND: Black individuals have a disproportionately higher burden of heart failure with reduced ejection fraction (HFrEF) relative to other racial and ethnic populations. We conducted a systematic review to determine the representation, enrollment trends, and outcomes of black patients in historic and contemporary randomized clinical trials (RCTs) for HFrEF. METHODS: We searched PubMed and Embase for RCTs of patients with chronic HFrEF that evaluated therapies that significantly improved clinical outcomes. We extracted trial characteristics and compared them by trial type. Linear regression was used to assess trends in enrollment among HFrEF RCTs over time. RESULTS: A total of 25 RCTs, 19 for pharmacotherapies and 6 (n=9,501) for implantable cardioverter defibrillators, were included in this analysis. Among these studies, there were 78,816 patients, 4,640 black (5.9%), and the median black participation per trial was 162 patients. Black race was reported in the manuscript of 14 (56.0%) trials, and outcomes by race were available for 12 (48.0%) trials. Implantable cardiac defibrillator trials enrolled a greater percentage of black patients than pharmacotherapy trials (7.1% vs 5.7%). Overall, patient enrollment among the 25 RCTs increased over time (P = .075); however, the percentage of black patients has decreased (P = .001). Outcomes varied significantly between black and white patients in 6 studies. CONCLUSIONS: Black patients are modestly represented among pivotal RCTs of individuals with HFrEF for both pharmacotherapies and implantable cardioverter defibrillators. The current trend for decreasing black representation in trials of HF therapeutics is concerning and must improve to ensure the generalizability for this vulnerable population. PMID- 29447784 TI - Design of DISCO-Direct or Subacute Coronary Angiography in Out-of-Hospital Cardiac Arrest study. AB - BACKGROUND: Acute coronary syndrome is a common cause of out-of-hospital cardiac arrest (OHCA). In patients with OHCA presenting with ST elevation, immediate coronary angiography and potential percutaneous coronary intervention (PCI) after return of spontaneous circulation are recommended. However, the evidence for this invasive strategy in patients without ST elevation is limited. Observational studies have shown a culprit coronary artery occlusion in about 30% of these patients, indicating the electrocardiogram's (ECG's) limited sensitivity. The aim of this study is to determine whether immediate coronary angiography and subsequent PCI will provide outcome benefits in OHCA patients without ST elevation. METHODS/DESIGN: We describe the design of the DIrect or Subacute Coronary angiography in Out-of-hospital cardiac arrest study (DISCO)-a pragmatic national, multicenter, randomized, clinical study. OHCA patients presenting with no ST elevation on their first recorded ECG will be randomized to a strategy of immediate coronary angiography or to standard of care with admission to intensive care and angiography after 3days at the earliest unless the patient shows signs of acute ischemia or hemodynamic instability. Primary end point is 30-day survival. An estimated 1,006 patients give 80% power (alpha = .05) to detect a 20% improved 30-day survival rate from 45% to 54%. Secondary outcomes include good neurologic recovery at 30days and 6months, and cognitive function and cardiac function at 6months. CONCLUSION: This randomized clinical study will evaluate the effect of immediate coronary angiography after OHCA on 30-day survival in patients without ST elevation on their first recorded ECG. PMID- 29447786 TI - High-sensitivity cardiac troponin T, left ventricular function, and outcome in non-ST elevation acute coronary syndrome. AB - BACKGROUND: Cardiac troponin (cTn) levels reflect infarct size and depressed left ventricular ejection fraction (LVEF) in patients with non-ST elevation acute coronary syndrome (NSTE-ACS). However, there is very limited information on whether cTn measured with a high-sensitivity (hs) assay would provide incremental prognostic information to the LVEF in NSTE-ACS patients. METHODS: This was a registry-based study (SWEDEHEART registry) investigating 20,652 NSTE-ACS patients with available information on hs-cTnT (highest level recorded during the hospitalization) and the LVEF estimated using echocardiography. All patients had been followed for 1 year. RESULTS: Hs-cTnT levels independently predicted major cardiovascular events (MACE) in cohorts with normal, slightly depressed, moderately depressed, and severely depressed LVEF. The adjusted hazard ratios in these cohorts were 1.18 (95% CI 1.13-1.23), 1.12 (95% CI 1.06-1.18), 1.12 (95% CI 1.06-1.19), and 1.21 (95% CI 1.13-1.30), respectively. Hs-cTnT levels were particularly predictive for cardiovascular mortality and readmission for heart failure. Excluding patients with previous cardiac disease did not affect the overall interrelations of hs-cTnT and LVEF with MACE. CONCLUSIONS: Hs-cTnT levels provide incremental prognostic value independent of the LVEF in patients with NSTE-ACS. Hs-cTnT is particularly predictive for MACE in patients with severely depressed LVEF but also in those with a normal LVEF. Accordingly, a normal LVEF should not be used as an argument not to target patients to thorough workup. PMID- 29447785 TI - Association of lipoprotein-associated phospholipase A2 and risk of incident atrial fibrillation: Findings from 3 cohorts. AB - BACKGROUND: Multiple prospective studies have established an association between inflammation and higher risk of atrial fibrillation (AF), but the association between lipoprotein-associated phospholipase A2 (Lp-PLA2) mass and activity and incident AF has not been extensively evaluated. METHODS: Using data from 10,794 Atherosclerosis Risk In Communities (ARIC) study participants aged 53-75 years, 5,181 Cardiovascular Health Study (CHS) participants aged 65 to 100 years, and 5,425 Multi-Ethnic Study of Atherosclerosis (MESA) participants aged 45-84 years, we investigated the association between baseline Lp-PLA2 levels and the risk of developing AF. Incident AF was identified in each cohort by follow-up visit electrocardiograms, hospital discharge coding of AF, or Medicare claims data. RESULTS: Over a mean of 13.1, 11.5, and 10.0 years of follow-up, 1,439 (13%), 2,084 (40%), and 615 (11%) incident AF events occurred in ARIC, CHS, and MESA, respectively. In adjusted analyses, each SD increment in Lp-PLA2 activity was associated with incident AF in both ARIC (hazard ratio [HR] 1.13, 95% CI 1.06 1.20) and MESA (HR 1.24, 95% CI 1.05-1.46). Each SD increment in Lp-PLA2 mass was also associated with incident AF in MESA (HR 1.25, 95% CI 1.11-1.41). No significant associations were observed among CHS participants. CONCLUSIONS: Although higher Lp-PLA2 mass and activity were associated with development of AF in ARIC and MESA, this relationship was not observed in CHS, a cohort of older individuals. PMID- 29447787 TI - Rationale and design of the comparison between a P2Y12 inhibitor monotherapy versus dual antiplatelet therapy in patients undergoing implantation of coronary drug-eluting stents (SMART-CHOICE): A prospective multicenter randomized trial. AB - BACKGROUND AND RATIONALE: Dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 inhibitor reduces thrombotic events in patients undergoing percutaneous coronary intervention (PCI), but these benefits come at the expense of increased risk of bleeding when compared with aspirin monotherapy. It is unclear whether P2Y12 inhibitor monotherapy might maintain anti-ischemic efficacy while reducing the bleeding risk compared with DAPT after implantation of the current generation of drug-eluting stents (DES). STUDY DESIGN: The SMART-CHOICE trial is a prospective, open-label, multi-center, and randomized study designed to test the non-inferiority of P2Y12 inhibitor monotherapy compared with aspirin plus a P2Y12 inhibitor after mandatory 3-month DAPT in patients undergoing PCI with current generation DES. A total of 3000 patients will be randomized to 1 of the 2 antiplatelet treatment strategy groups. Randomization will be stratified by stent type (cobalt-chromium everolimus-eluting stents, platinum-chromium everolimus eluting stents, and sirolimus-eluting stents with bioresorbable polymer), P2Y12 inhibitors (clopidogrel, prasugrel, and ticagrelor), clinical presentation (acute coronary syndrome and stable ischemic heart disease), and investigational centers. The primary end point is a composite of all-cause death, myocardial infarction, and cerebrovascular events at 12 months after the index procedure. The key secondary end points are definite/probable stent thrombosis defined by the Academic Research Consortium, and bleeding defined by Bleeding Academic Research Consortium type 2-5. CONCLUSIONS: The SMART-CHOICE trial aims to examine the non-inferiority of monotherapy with one of any available oral P2Y12 inhibitors versus conventional DAPT of an identical P2Y12 inhibitor plus aspirin in a broad spectrum of patients receiving representative current-generation DES. PMID- 29447788 TI - The influence of febuxostat on coronary artery endothelial dysfunction in patients with coronary artery disease: A phase 4 randomized, placebo-controlled, double-blind, crossover trial. AB - BACKGROUND: The xanthine oxidase (XO) system is a significant source of vascular oxidative stress, which is believed to impair endothelial function, an important contributor to atherosclerotic disease. We tested whether febuxostat, a potent XO inhibitor, improves coronary endothelial function (CEF) in patients with stable coronary artery disease (CAD) in a single-center, randomized, placebo-controlled, double-blind crossover trial. METHODS: CEF was measured using noninvasive magnetic resonance imaging (MRI) assessment of changes in 30 patients with stable CAD and baseline impaired CEF. Patients received either febuxostat or placebo for 6 weeks and then were crossed over to the alternative for an additional 6 weeks. MRI-detected changes in coronary flow and in coronary cross-sectional area from rest to isometric handgrip exercise, a known endothelial-dependent stressor, were measured at the end of each 6 week period. RESULTS: Mean serum urate levels were lower at the end of the 6-week febuxostat period (2.9+/-0.8mg/dL) than at the end of the 6-week placebo period (5.9+/-0.04, P<.001). However, there were no significant differences in any of the CEF parameters measured at the end of the febuxostat and placebo periods. CONCLUSIONS: In summary, although XO inhibition with febuxostat was well tolerated and lowered serum urate, it did not improve the primary end point of the study, CEF measured using MRI after 6 weeks of treatment. In conclusion, these findings suggest that short-term inhibition of XO does not significantly improve impaired CEF in patients with stable CAD. PMID- 29447789 TI - Comprehensive electrocardiogram-to-device time for primary percutaneous coronary intervention in ST-segment elevation myocardial infarction: A report from the American Heart Association mission: Lifeline program. AB - BACKGROUND: Assessing hospital-related network-level primary percutaneous coronary intervention (PCI) performance for ST-segment elevation myocardial infarction (STEMI) is challenging due to differential time-to-treatment metrics based on location of diagnostic electrocardiogram (ECG) for STEMI. METHODS: STEMI patients undergoing primary PCI at 588 PCI-capable hospitals in AHA Mission: Lifeline (2008-2013) were categorized by initial STEMI identification location: PCI-capable hospitals (Group 1); pre-hospital setting (Group 2); and non-PCI capable hospitals (Group 3). Patient-specific time-to-treatment categories were converted to minutes ahead of or behind their group-specific mean; average time to-treatment difference for all patients at a given hospital was termed comprehensive ECG-to-device time. Hospitals were then stratified into tertiles based on their comprehensive ECG-to-device times with negative values below the mean representing shorter (faster) time intervals. RESULTS: Of 117,857 patients, the proportion in Groups 1, 2, and 3 were 42%, 33%, and 25%, respectively. Lower rates of heart failure and cardiac arrest at presentation are noted within patients presenting to high-performing hospitals. Median comprehensive ECG-to device time was shortest at -9 minutes (25th, 75th percentiles: -13, -6) for the high-performing hospital tertile, 1 minute (-1, 3) for middle-performing, and 11 minutes (7, 16) for low-performing. Unadjusted rates of in-hospital mortality were 2.3%, 2.6%, and 2.7%, respectively, but the adjusted risk of in-hospital mortality was similar across tertiles. CONCLUSIONS: Comprehensive ECG-to-device time provides an integrated hospital-related network-level assessment of reperfusion timing metrics for primary PCI, regardless of the location for STEMI identification; further validation will delineate how this metric can be used to facilitate STEMI care improvements. PMID- 29447790 TI - Fine particulate matter and incident coronary heart disease in the REGARDS cohort. AB - : Chronic exposure to fine particulate matter (PM2.5) is accepted as a causal risk factor for coronary heart disease (CHD). However, most of the evidence for this hypothesis is based upon cohort studies in whites, comprised of either only males or females who live in urban areas. It is possible that many estimates of the effect of chronic exposure to PM2.5 on risk for CHD do not generalize to more diverse samples. METHODS: Therefore, we estimated the relationship between chronic exposure to PM2.5 and risk for CHD in among participants in the REasons for Geographic And Racial Differences in Stroke (REGARDS) cohort who were free from CHD at baseline (n=17,126). REGARDS is a sample of whites and blacks of both genders living across the continental United States. We fit Cox proportional hazards models for time to CHD to estimate the hazard ratio for baseline 1-year mean PM2.5 exposure, adjusting for environmental variables, demographics, and other risk factors for CHD including the Framingham Risk Score. RESULTS: The hazard ratio (95% CI) for a 2.7-MUg/m3 increase (interquartile range) 1-year mean concentration of PM2.5 was 0.94 (0.83-1.06) for combined CHD death and nonfatal MI, 1.13 (0.92-1.40) for CHD death, and 0.85 (0.73-0.99) for nonfatal MI. We also did not find evidence that these associations depended upon overall CHD risk factor burden. CONCLUSIONS: Our results do not provide strong evidence for an association between PM2.5 and incident CHD in a heterogeneous cohort, and we conclude that the effects of chronic exposure to fine particulate matter on CHD require further evaluation.

PMID- 29447793 TI - Clinical role of vitamin D in prognosis of otitis media with effusion. AB - OBJECTIVE: To investigate the clinical role of Vitamin D in prognosis of Otitis media with effusion. METHODS: This prospective-controlled study was conducted at otolaryngology department in Duzce University, Turkey. The study group comprised children who were diagnosed with Otitis media with effusion between September 2016 and February 2017. Control group was conducted with children underwent circumcision or inguinal hernia repair operations that confirmed with ENT examination they do not have any sign of otitis media. After 3 months of follow up without any treatment, unresolved cases who were accepted as chronic otitis media with effusion were operated under general anesthesia for ventilation tube application. Study and control groups were assessed depending on the serum 25(OH)Vitamin D levels at the end of 3 months; < 15 ng/mL was accepted as vitamin D deficiency. The results were compared with the control group in terms of vitamin D levels. Also, subgroup analysis was performed addressing to the complete recovery otitis media with effusion and chronic otitis media with effusion. RESULTS: One-hundred-seventy-four children with otitis media with effusion and 80 control patients were included to the study. One-hundred-eight (62%) out of 174 patients with otitis media with effusion was completely recovered after a 3-months follow up. Of those 66 out of 174 children, they had persistent diseases, underwent ventilation tube insertion after a 3-months follow up. The mean 25(OH)Vitamin D level was 18.98 +/- 10.60 in otitis media with effusion group and 28.07 +/- 14.10 in control group and the difference was statistically significant between the study and control group (p < 0.001). Vitamin D deficiency was observed in 33 out of 66 patients (50.0%) in chronic otitis media with effusion group whilst 35 out of 108 patients (32.4%) in complete recovery otitis media with effusion group (p = 0.021). The rate of 25(OH)Vitamin D deficiency was 25% in control group which was statistically different from chronic otitis media with effusion and recovery chronic otitis media with effusion groups (p = 0.006). CONCLUSIONS: This study not only shows the relationship between Vitamin D and otitis media with effusion development, but also demonstrates the effects of Vitamin D on otitis media with effusion prognosis. There is a significant association between 25(OH)Vitamin D deficiency and follow-up outcomes of otitis media with effusion. PMID- 29447794 TI - Plasticity after pediatric cochlear implantation: Implication from changes in peripheral plasma level of BDNF and auditory nerve responses. AB - INTRODUCTION: Sensory neural hearing loss could lead to some structural and physiological changes in the auditory pathways, such as alteration in the expression of neurotrophins. These factors, especially Brain-Derived Neurotrophic Factor (BDNF), play an important role in synaptic functions and experience related plasticity. Restoring cochlear function after hearing loss is possible through cochlear implantation (CI). Evaluation of the blood concentration changes of neurotrophins as prerequisites of plasticity could help scientists to determine the prognosis of CI as in the candidacy procedure or enhancing prosthesis function by adding the exact needed amount of BDNF to the electrode array. METHODS: Here we have studied the plasma BDNF concentration before CI surgery and 6 months after using CI device in 15 pediatric CI recipients and compared this level with changes of BDNF concentration in 10 children who were using hearing aid (H.A). In addition, we searched for a possible correlation between post-surgery plasma BDNF concentration and electrical compound action potential (ECAP) and comfort-level (C-level) thresholds. RESULTS: Plasma BDNF concentration in children with CI increased significantly after CI surgery, while this difference in H.A group was not significant. Analysis of repeated measures of ECAP and C-level thresholds in CI group showed that there were some kinds of steadiness during follow- up sessions for ECAP thresholds in basal and E16 of middle electrodes, whereas C-level thresholds for all selected electrodes increased significantly up to six months follow-up. Interestingly, we did not find any significant correlation between post-surgery plasma BDNF concentration and ECAP or C-level threshold changes. CONCLUSION: It is concluded that changes in C-level threshold and steady state of ECAP thresholds and significant changes in BDNF concentration could be regarded as an indicator of experienced-related plasticity after CI stimulation. PMID- 29447795 TI - Modified approach for pediatric external cricopharyngeal myotomy. AB - Pediatric cricopharyngeal achalasia is an uncommon but important cause of oropharyngeal dysphagia. Failure of upper esophageal sphincter relaxation is the currently understood pathophysiology. Therapies include balloon dilation, botulinum toxin injection, and endoscopic or open cricopharyngeal myotomy (CPM). Open CPM is usually performed at the posterior midline of the cricopharyngeus and can be a risky procedure given concern for esophageal perforation and damage to the recurrent laryngeal nerve. Here, we present a novel modified technique for open CPM using a superficial anterolateral transection approach in the case of a young male with refractory cricopharyngeal achalasia.

AB - The endoscopic transterygoid approach to the petrous apex is a feasible/alternative approach in carefully selected patients with specific favorable anatomy, even children. This approach, unlike traditional approaches, spares cochlear and vestibular function. We report a case of a six-year-old boy with embryonal rhabdomyosarcoma of the petrous apex that was diagnosed via the endoscopic transpterygoid approach. PMID- 29447797 TI - The anatomic applicability of transcanal endoscopic ear surgery in children. AB - OBJECTIVE: The feasibility of TEES in dealing with pediatric middle ear disease is still under investigation. The goal of this study was to compare anatomical dimensions of the EAC between children and adults, and to analyze the anatomic applicability of TEES in children. METHODS: Forty pediatric (18 years old and younger) and 20 adult patients who received TB-HRCT to evaluate middle ear conditions were enrolled from December 2010 to December 2015. Dimensions including the diameters of the EAC orifice, isthmus and tympanic membrane annulus, the length of EAC, the height of the middle ear, and the angle between tympanic membrane and EAC axis were determined according to the TB-HRCT data. RESULTS: The diameters of the EAC orifice and isthmus and length of EAC in the pediatric patients were slightly smaller than those in the adult patients. The anatomical dimensions of middle ear were similar in both groups. Simple regression analysis indicated that the diameters of the EAC orifice and isthmus and the length of the EAC were positively correlated with the age of the pediatric patients. In the pediatric patients, 67 ears (83.75%) had an EAC isthmus diameter larger than 4 mm and are sufficient with a 3-mm endoscope manipulation. CONCLUSION: TEES is applicable for most pediatric patients using an endoscope with a diameter of 3 mm or smaller. With an appropriate endoscope and instruments, TEES is a safe and effective alternative to treat pediatric middle ear disease. PMID- 29447798 TI - Papillary thyroid carcinoma presenting as acute suppurative thyroiditis: A case report and review of the literature. AB - Acute suppurative thyroiditis is a rare, potentially life-threatening condition. We report the case of a 17-year-old male who initially presented with a thyroid abscess. Due to persistent symptoms and lack of evidence for underlying predisposing factors, he was followed closely and subsequently diagnosed with papillary thyroid cancer. He was successfully managed with surgery. His clinical course, radiological evaluation, and pathology reports are presented here along with a review of the literature. This case of papillary thyroid cancer highlights the need for close follow-up of patients presenting with a thyroid abscess, when other predisposing risk factors are not evident. PMID- 29447799 TI - Iatrogenic Cushing's syndrome and adrenal insufficiency in infants on intranasal dexamethasone drops for nasal obstruction - Case series and literature review. AB - The use of intranasal steroid drops for nasal obstruction in infants is common practice and can prevent more invasive surgical procedures; however, it is not without complication. We describe 2 cases of iatrogenic Cushing's secondary to nasal steroids in infants with nasal obstruction, discuss the etiology of this unusual complication, and review previous literature reports. While reporting in the literature is sparse, these cases highlight the risk of development of adrenal insufficiency with usage of nasal steroid drops in infants as well as the need for close monitoring of administration and tapering of the drops. Additionally, we suggest an approach to the infant with symptomatic nasal obstruction that addresses the usage of intranasal steroid drops and emphasizes the need for quick tapering and possible endocrine consultation when appropriate. PMID- 29447800 TI - Reliability and validity of the Chinese pediatric voice handicap index. AB - OBJECTIVES: To evaluate the reliability and validity of the Chinese version of pediatric voice handicap index (pVHI). MATERIAL AND METHODS: The original English version-pVHI was translated into Chinese. Parents of 52 children with voice dysphonia and 43 children with no history or symptoms of voice problems were asked to fill the Chinese pVHI questionnaires twice with an interval of 2 weeks. GRB (Grade, Roughness, Breathiness) scale was used for perceptual assessment by two otolaryngologists and one speech pathologist for each child's voice. The internal consistency was assessed using Cronbach's alpha coefficient. Pearson's correlation coefficient was used to evaluate the test-retest reliability. The Kendall's coefficient of concordance W was used to assess the consistency of GRB scores of 3 voice specialists. The nonparametric Mann-Whitney test was used to assess the differences between the dysphonia group and controls. The correlation between pVHI and GRB scores were assessed using Pearson's correlation coefficient. RESULTS: The internal consistency of total score and three subscales scores of Chinese pVHI were 0.788-0.944. The test-retest reliability was 0.631 0.887(P < .001). The pVHI scores of control group significantly were lower than the pathological group (P = .000). The GRB scores of 3 voice specialists have an excellent consistency (W = 0.694-0.807, P = .000). The pVHI scores positively correlated with GRB assessment (P < .01). CONCLUSIONS: The Chinese version of pVHI had a good reliability and validity. It can be applicable and useful supplementary tool for evaluating parents' perception of their children's dysphonia. PMID- 29447801 TI - A clinical pathway for the postoperative management of hypocalcemia after pediatric thyroidectomy reduces blood draws. AB - OBJECTIVES: Postoperative calcium management is challenging following pediatric thyroidectomy given potential limitations in self-reporting symptoms and compliance with phlebotomy. A protocol was created at our tertiary children's institution utilizing intraoperative parathyroid hormone (PTH) levels to guide electrolyte management during hospitalization. The objective of this study was to determine the effect of a new thyroidectomy postoperative management protocol on two primary outcomes: (1) the number of postoperative calcium blood draws and (2) the length of hospital stay. STUDY DESIGN: Institutional review board approved retrospective study (2010-2016). METHODS: Consecutive pediatric total thyroidectomy and completion thyroidectomy +/- neck dissection cases from 1/1/2010 through 8/5/2016 at a single tertiary children's institution were retrospectively reviewed before and after initiation of a new management protocol. All cases after 2/1/2014 comprised the experimental group (post protocol implementation). The pre-protocol control group consisted of cases prior to 2/1/2014. Multivariable linear and Poisson regression models were used to compare the control and experimental groups for outcome measure of number of calcium lab draws and hospital length of stay. RESULTS: 53 patients were included (n = 23, control group; n = 30 experimental group). The median age was 15 years. 41 patients (77.4%) were female. Postoperative calcium draws decreased from a mean of 5.2 to 3.6 per day post-protocol implementation (Rate Ratio = 0.70, p < .001), adjusting for covariates. The mean number of total inpatient calcium draws before protocol initiation was 13.3 (+/-13.20) compared to 7.2 (+/-4.25) in the post-protocol implementation group. Length of stay was 2.1 days in the control group and 1.8 days post-protocol implementation (p = .29). Patients who underwent concurrent neck dissection had a longer mean length of stay of 2.32 days compared to 1.66 days in those patients who did not undergo a neck dissection (p = .02). Hypocalcemia was also associated with a longer mean length of stay of 2.41 days compared to 1.60 days in patients who did not develop hypocalcemia (p < .01). CONCLUSIONS: The number of calcium blood draws was significantly reduced after introduction of a standardized protocol based on intraoperative PTH levels. The hospital length of stay did not change. Adoption of a standardized postoperative protocol based on intraoperative PTH levels may reduce the number of blood draws in children undergoing thyroidectomy. PMID- 29447802 TI - Effects of maxillary protraction appliances on airway dimensions in growing class III maxillary retrognathic patients: A systematic review and meta-analysis. AB - OBJECTIVES: The purpose of this study was to assess, through a systematic review and meta-analysis, the efficacy of maxillary protraction appliances (MPAs) on improving pharyngeal airway dimensions in growing class III patients with maxillary retrognathism. METHODS: An electronic search in PubMed, Cochrane Library, Web of Science, and EMBASE was until September 2nd, 2017. The assessments of methodological quality of the selected articles were performed using the Newcastle-Ottawa Scale. Review Manager 5.3 (provided by the Cochrane Collaboration) was used to synthesize the effects of MPAs on pharyngeal airway dimensions. RESULTS: Following full-text articles evaluation for eligibility, 6 studies (168 treated subjects and 140 untreated controls) were included in final quantitative synthesis and they were all high-quality. Compared to untreated control groups, the treatment groups had increased significantly nasopharyngeal airway dimensions with the following measurements: PNS-AD1 (fixed: mean difference, 1.33 mm, 95% CI, 0.48mm-2.19 mm, P = .002), PNS-AD2 (random: mean difference, 1.91 mm, 95% CI, 0.02mm-3.81 mm, P = .05), aerial nasopharyngeal area (fixed: mean difference, 121.91 mm2, 95% CI, 88.70 mm2-155.11 mm2, P < .00001) and total nasopharyngeal area (fixed: mean difference, 142.73 mm2, 95% CI, 107.90 mm2-177.56 mm2, P < .00001). Meanwhile, McNamara's upper pharynx dimension (fixed: mean difference, 0.96 mm, 95% CI, 0.29mm-1.63 mm, P = .005), which was highly related to post-palatal airway dimension, was also improved significantly. However, no statistically significant differences in adenoidal nasopharyngeal area (P > .05) and McNamara's lower pharynx dimension (P > .05) existed. CONCLUSIONS: MPAs can increase post-palatal and nasopharyngeal airway dimensions in growing skeletal class III subjects with maxillary retrusion. It may be suggested that MPAs have the potential to reduce the risk of obstructive sleep apnea syndrome in children with maxillary retrusion by enlarging airway space. PMID- 29447803 TI - Maternal knowledge and attitudes to universal newborn hearing screening: Reviewing an established program. AB - OBJECTIVES: To facilitate early diagnosis of infants with hearing loss, a universal newborn hearing screening program (UNHS) has been implemented in Hong Kong's public hospitals for over a decade. However, there have been no known studies investigating parent attitudes to, and satisfaction with, UNHS since its launch in Hong Kong. The present study aimed to investigate knowledge of UNHS as well as infant hearing development, and attitudes and satisfaction with UNHS, in Hong Kong mothers with newborns. The study was designed to help evaluate and improve an established UNHS public hospital program, based on the perspectives of service users. METHODS: A researcher-developed questionnaire was administered to 102 mothers whose newborn had received UNHS in the postnatal wards of a large public hospital in Hong Kong. The questionnaire considered parental knowledge of UNHS and infant hearing development, attitudes and satisfaction toward public hospital UNHS. In the knowledge dimension, parents' preferred time and location for pre-test information delivery, interpretation of screening results, and knowledge of hearing developmental milestones were surveyed. In addition, maternal attitudes to and satisfaction with UNHS screening services, the potential impact of UNHS on parent emotions and parent-baby bonding, attitudes toward informed consent, and willingness to comply with diagnostic assessment referral were also be surveyed. RESULTS: Mean participant scores on knowledge of infant hearing development were relatively low (M = 2.59/6.0, SD = 0.90). Many mothers also underestimated the potential ongoing risks of hearing impairment in babies. Around 80% of mothers thought an infant could not have hearing impairment after passing the screening. In addition, one-third of mothers thought a baby could not later develop hearing impairment in infancy or childhood. In terms of attitudes and satisfaction, participants gave somewhat negative ratings for questions regarding receiving sufficient information about the screening (M = 2.90/5.0, SD = 1.27), screening procedure (M = 2.20/5.0, SD = 1.08), and sufficiency of information about results (M = 2.87/5.0, SD = 1.14). Nonetheless, participants gave positive ratings concerning whether screening could lead to early diagnosis (M = 4.61/5.0, SD = 0.57) and over 95% of mothers supported UNHS despite potential for false positive results. Mothers reported a high willingness to bring their baby to follow-up assessments if required (M = 4.53/5.0, SD = 0.56). Participants gave positive ratings for their level of satisfaction with the time and location of first UNHS information provision (M = 4.34/5.0, SD = 0.80) and the way permission was asked for screening the baby (M = 4.04/5.0, SD = 0.97) but alternative procedures were also recommended. Most recommendations focused on providing more information about the test and a more detailed explanation of screening results. CONCLUSIONS: The survey results highlighted the need to provide more information to parents about infant hearing development to support home monitoring for signs of hearing loss after UNHS, as well as more detailed explanation and information regarding hearing screening and the implications of results to parents. Regardless of location, surveys of this type may provide valuable support for UNHS program quality assurance. PMID- 29447804 TI - Long-term follow-up with mention of complications in pediatric microvascular mandibular reconstruction. AB - The fibular free flap has become the gold standard for mandibular reconstruction. Despite its vast array of benefits, this procedure has the potential for several complications. In the pediatric setting, the immature skeleton sets the stage for an increased risk of future skeletal abnormalities, both in the jaw, and in the donor site. Herein we describe the case of a toddler who underwent mandibular reconstruction using a fibula free flap and, years later, subsequently developed ankle instability as a result of residual fibula migration. This indicates the need for careful consideration of long-term issues in the growing pediatric skeleton prior to surgery. PMID- 29447805 TI - Characterization of newborn hearing screening failures in multigestational births. AB - OBJECTIVE: To define the rate and characterize the type of newborn hearing screening failures in multigestational births. METHODS: Retrospective chart review of all multigestational births that occurred in a 10-year period (2002 2012) in which at least one newborn failed newborn hearing screening at two tertiary care hospitals in the Northwell Health System. RESULTS: Out of 125,405 total births, we identified 2961 multigestational births, of which 59 (2.0%) newborns failed newborn hearing screening. None of their 66 twin/triplet siblings failed their newborn hearing screens. Of 43 newborns that returned for follow-up, 56.0% (24/43) had confirmed hearing loss, resulting in an overall rate of 0.81% in all multigestational newborns with hearing loss. Of 19 infants that passed repeat testing, two were judged to need myringotomy tube placement. Twenty-four infants had a confirmed hearing loss, 11 of which had sensorineural hearing loss (0.37%), and 13 with a conductive or mixed hearing loss (0.44%). CONCLUSIONS: We identified a greater than expected risk of conductive hearing loss, not attributable to otitis media, than sensorineural hearing loss in this population. These observations are consistent with the increased risk of birth defects in multigestational births. PMID- 29447806 TI - Pediatric Meniere's disease. AB - OBJECTIVE: This study adopted an inner ear test battery comprising audiometry, and ocular vestibular evoked myogenic potential (oVEMP), cervical VEMP (cVEMP), and caloric tests to investigate the sequence of inner ear deficits in pediatric Meniere's disease (MD). METHODS: From 2005 to 2016, a total of 24 MD children aged <15 years old underwent otoscopy, CT scan, blood test, and an inner ear test battery. Nine subjects were males and 15 were females, with mean age of 12 years. Right ear was affected in 3 patients, left ear in 5 patients, and both ears in 16 patients (67%). Eight (33%) of the 24 MD children had positive family history. RESULTS: Inner ear deficits in MD children ran from abnormal hearing (25%) to abnormal cVEMP (20%), oVEMP (13%), and caloric (12%) tests, exhibiting a significantly declining sequence from the cochlea, to the saccule, utricle and semicircular canals. Analysis between the laterality and family history revealed a significantly positive correlation. CONCLUSION: Pediatric MD is rare, accounting for 2.3% prevalence in MD patients. The inner ear deficits in pediatric MD showed a significantly declining sequence from the cochlea, to the saccule, utricle and semicircular canals, mimicking the sequence in adult MD. One third MD children had positive family history, which may explain the high rate of bilateral affliction and symmetrical hearing levels on both ears. PMID- 29447807 TI - Sialoendoscopy for treatment of juvenile recurrent parotitis: The Brescia experience. AB - OBJECTIVE: To evaluate the role of sialoendoscopy associated with steroid irrigation for juvenile recurrent parotitis (JRP) at a tertiary referral hospital. METHODS: Clinical records of patients affected by JRP and treated with operative sialoendoscopy between June 2011 and April 2017 were retrospectively reviewed. Data on demographics, number of acute episodes per year before and after surgery, characteristics of the surgical procedure, hospitalization time, and rate of complications were collected. The outcome of the procedure was measured by comparing the number of episodes of parotid swelling before and after salivary endoscopic treatment. RESULTS: Twenty-three patients for a total of 34 operative sialoendoscopies were included in the study. Before the surgical endoscopic procedure, the mean number of parotid swelling was 10 episodes per year. At sialoendoscopy, typical endoscopic findings such as mucous plugs, stenosis of the duct, intraductal debris, and pale ductal appearance were evident. All patients were discharged on the first postoperative day. A significant decrease in the number of swelling episodes per year was observed compared to the preoperative rate (p = .0004). Complete resolution of the disorder was obtained in 35% of patients. CONCLUSIONS: Operative sialoendoscopy with steroid irrigation can be considered a valid therapeutic treatment for JRP. The technique is conservative, effective, safe, and, potentially repeatable. Short hospitalization time, rapid recovery, absence of peri-operative complications, and a high rate of good outcomes are the main advantages of this treatment. PMID- 29447808 TI - Hold your horses: A comparison of human laryngomalacia with analogous equine airway pathology. AB - OBJECTIVES: Laryngomalacia is the most common cause of stridor in infants. Dynamic airway collapse is also a well-recognised entity in horses and an important cause of surgical veterinary intervention. We compare the aetiology, clinical features and management of human laryngomalacia with equine dynamic airway collapse. METHODS: A structured review of the PubMed, the Ovid Medline and the Cochrane Collaboration databases (Cochrane Central Register of Controlled Trials, Cochrane Database of Systemic Reviews). RESULTS: There are numerous equine conditions that cause dynamic airway collapse defined specifically by the anatomical structures involved. Axial Deviation of the Aryepiglottic Folds (ADAF) is the condition most clinically analogous to laryngomalacia in humans, and is likewise most prevalent in the immature equine airway. Both conditions are managed either conservatively, or if symptoms require it, with surgical intervention. The operative procedures performed for ADAF and laryngomalacia are technically comparable. CONCLUSION: Dynamic collapse of the equine larynx, especially ADAF, is clinically similar to human laryngomalacia, and both are treated in a similar fashion. PMID- 29447809 TI - Difficult airway intubation simulation using Bonfils fiberscope and rigid fiberscope for surgical training. AB - INTRODUCTION: Pediatric otolaryngologists are frequently called to assist in difficult airway management in newborns with Pierre Robin Sequence (PRS) who have microretrognathia, glossoptosis, and an anterior larynx. The Bonfils fiberscope (BF) is a curved rigid scope designed to provide superior visualization in the anterior larynx. OBJECTIVE: (1) to assess whether BF provides an improvement in intubation success rate, time to intubation, or airway visualization as compared to rigid fiberscope (RF) in a difficult airway simulation setting and (2) to determine whether a training program for BF can improve time to intubation through practice trials. METHODS: Six right-handed trainees completed five trials on each of the three following airway models using the BF and RF: normal anatomy, anterior larynx and PRS. The normal larynx model was intubated only with RF. Main outcome measures were the time needed for tracheal intubation and Cormack-Lehane classification (1-4). RESULTS: The majority of the intubation trials showed a statistically significant difference between first and last completion times (p < .05) suggesting construct validity. Only the anterior larynx trials with BF did not demonstrate an improvement in time to intubation between first and last attempts (p < .3125). For the PRS retrognathia model, there was no statistically significant difference in time to intubation between using the BF and the RF (p < .44); in the anterior larynx model, the RF yielded a faster time to intubation than the BF on the final trial attempts (p < .0313). By Cormack-Lehane classification measures, laryngeal visualization by the BF was better than RF in the PRS manikin (p < .0022) while there was no significant difference in grade scores for the anterior larynx manikin (p < .45). All six trainees reported an improved visualization of the larynx with the BF compared to the RF for both the anterior larynx and PRS manikins; at the end of the trial runs, all participants noted an improvement in comfort level using the BF. CONCLUSION: The difficult airway simulation model is feasible for surgical training. BF adds superior visualization of the anterior larynx in PRS. Otolaryngology training programs may include BF as a supplemental tool in addition to RF as a part of the airway equipment training since there is significant improvement in time to intubation with consecutive practice trials and superior laryngeal visualization.

AB - INTRODUCTION: Primary Ciliary Dyskinesia (PCD) describes a group of inherited disorders that result in abnormal ciliary motion leading to mucous stasis. Clinical features include almost universally otitis media with effusion (OME), particularly in infants. PCD patients provide us with a cohort of patients with OME that is not treated with ventilatory tube (VT) insertion as these have been shown to result in frequent complications including chronic otorrhoea, early extrusion and persistent perforation without significant improvement to hearing in the long term. This cohort was used to investigate whether children with PCD and OME not treated with VT were predisposed to cholesteatoma formation in the setting of a paediatric quaternary referral centre. METHODS: A retrospective chart review was performed of all the children attending a multi-disciplinary PCD clinic at a national quaternary referral centre with a diagnosis of OME. We reviewed otoscopic findings, and audiometry and tympanometry results. We assessed the children in four groups: Watchful waiting, hearing aids, VT, and VT and hearing aids. RESULTS: One-hundred-and-one of 107 patients included in the study had a diagnosis of otitis media with effusion. No child with OME and PCD was diagnosed with a cholesteatoma during the follow up period. The only children who had insertion of a ventilatory tube were those who had the procedure prior to the formal diagnosis of PCD. We found a significant complication rate in the children with VT insertion. Hearing improved over time. The prevalence of retraction pockets in untreated OME was 1.72% (3 out of 174 ears). CONCLUSIONS: In children with PCD, OME is an almost universal finding in younger children, but not in adolescents. The study supports the current preference to avoid VT insertion in children with PCD as it confers a significantly higher rate of complications. No cases of cholesteatoma were found in this cohort of PCD children with OME managed without VTs. PMID- 29447811 TI - Sensorineural and conductive hearing loss in infants diagnosed in the program of universal newborn hearing screening. AB - OBJECTIVE: The aim of this study was to analyze infants diagnosed with sensorineural or conductive hearing deficit and to identify risk factors associated with these defects. MATERIAL AND METHODS: A retrospective analysis of infants diagnosed with hearing deficit based on the database of the universal newborn hearing screening program and medical records of the patients. RESULTS: 27 935 infants were covered by the universal neonatal hearing screening program. 109 (0.39%) were diagnosed with hearing deficit and referred for treatment and rehabilitation. 56 (51.4%) children were diagnosed with conductive, 38 (34.9%) with sensorineural and 15 (13.8%) with mixed type of hearing deficit. Children with sensorineural hearing deficit more frequently suffered from hyperbilirubinemia (p < 0.05), while infants with conductive hearing loss were more frequently diagnosed with isolated craniofacial anomalies (p < 0.05). The prevalence of other risk factors did not differ between the groups. Sensorineural hearing deficit occurred almost 3 times more often bilaterally than unilaterally (p < 0.05). In other types of hearing deficit, the difference was not significant. In children with conductive and mixed type of hearing loss the impairment was mainly mild while among those with sensorineural hearing deficit in almost 45% it was severe and profound (p < 0.05). When analyzing the consistency between hearing screening test by means of otoacoustic emissions and the final diagnosis of hearing deficit we found that the highest agreement rate was observed in children with sensorineural hearing loss (p < 0.01). CONCLUSIONS: The prevalence of most risk factors of hearing deficit was similar in children with sensorineural, conductive and mixed type of hearing loss, only hyperbilirubinemia seemed to predispose to sensorineural hearing deficit and isolated craniofacial malformations seemed to be associated with conductive hearing loss. Sensorineural hearing deficit usually occurred bilaterally and was severe or profound, while conductive and mixed type of hearing deficit were most often of mild degree. Most children with the final diagnosis of sensorineural hearing deficit had positive result of hearing screening by means of otoacoustic emissions. PMID- 29447812 TI - Total serum bilirubin levels and sensorineural hearing loss in the US adolescents: NHANES 2007-2010. AB - OBJECTIVE: We aimed to investigate whether current levels of total serum bilirubin are associated with different subtypes of sensorineural hearing loss (SNHL) in adolescents. METHODS: A set of cross-sectional data from the National Health and Nutrition Examination Survey (NHANES) (2007-2010) was used. A subset of 1404 adolescents was sampled for measurements of total serum bilirubin, tympanometry, and average pure tone threshold at low-frequencies (LPTA: 500, 1000, 2000 Hz) or high-frequencies (HPTA: 3000, 4000, 6000, and 8000 Hz). SNHL was defined as the hearing loss that had type A tympanograms with a peak admittance of 0.3 ml or greater. Associations between serum bilirubin (square root transformed) and different subtypes of SNHL were evaluated using binary or multinomial logistic regression models with 4-year sampling weights. The bootstrap method was used for estimation of variance and 10-fold cross-validation for assessment of overfitting issue. RESULTS: Total serum bilirubin levels were found to be associated with any high-frequency (HPTA>15 dB in at least one ear, adjusted odds-ratio (ORa)(bootstrap 95% confidence interval) = 3.29(1.31-8.19), p = 0.011), but not with any low-frequency (LPTA>15 dB in at least one ear), SNHL in the US adolescents. Furthermore, high-frequency SNHL with HPTA>15 dB in both ears (bilateral) or HPTA>=25 dB in at least one ear, compared to that with HPTA>15 dB in one ear only (unilateral) or HPTA = 15-25 dB in at least one ear, had a stronger association with total serum bilirubin levels (ORa = 5.37(1.27 22.65), p = 0.022 for bilateral; ORa = 2.64(0.84-8.25), p = 0.094 for unilateral; ORa = 5.00(0.95-26.58), p = 0.058 for HPTA>=25 dB in at least one ear; as well as ORa = 3.06(1.15-8.25), p = 0.025 for HPTA = 15-25 dB in at least one ear). No severe overfitting problems were found. CONCLUSION: Our findings suggest that current levels of total serum bilirubin may be informative in predicting and/or targeting high-frequency SNHL in the US adolescents.

AB - OBJECTIVES: Cochlear implant (CI) greatly enhances auditory performance as compared to hearing aids and has dramatically affected the educational and communication outcomes for profoundly deaf children. Universiti Kebangsaan Malaysia (UKM) pioneered CI program in 1995 in the South East Asia. We would like to report the long-term outcomes of UKM paediatric cochlear implantation in terms of: the proportion of children who were implanted and still using the device, the children's modes of communication, their educational placements, and their functional auditory/oral performance. We also examined the factors that affected the outcomes measured. STUDY DESIGN: This was a cross sectional observational study. METHODS: Two sets of questionnaires were given to 126 parents or primary caregivers of the implantees. The first set of questionnaire contained questions to assess the children's usage of CI, their types of education placement, and their modes of communication. The second set of questionnaire was the Parent's Evaluation Of Aural/Oral Performance of Children (PEACH) to evaluate the children's auditory functionality. RESULTS: Our study showed that among the implantees, 97.6% are still using their CI, 69.8% communicating orally, and 58.5% attending mainstream education. For implantees that use oral communication and attend mainstream education, their mean age of implantation is 38 months. This is significantly lower compared to the mean age of implantation of implantees that use non-oral communication and attend non-mainstream education. Simple logistic regression analysis shows age of implantation reliably predicts implantees (N = 126) would communicate using oral communication with odds ratio of 0.974, and also predict mainstream education (N = 118) with odds ratio of 0.967. The median score of PEACH rating scale is 87.5% in quiet, and this significantly correlates with an earlier age of implantation (r = -0.235 p = 0.048). CONCLUSIONS: UKM Cochlear Implant Program has achieved reasonable success among the pediatric implantees, with better outcomes seen in those implanted at the age of less than 4 years old. PMID- 29447814 TI - Spontaneous retropharyngeal and mediastinal thoracic duct cyst in an infant with respiratory distress. AB - Thoracic duct cysts (TDC) within the retropharyngeal space and mediastinum are exceedingly rare lesions, with the majority related to trauma or neoplasm. We describe a case of an otherwise healthy 8-month-old boy who presented with severe respiratory distress, which was found to be caused by a large, spontaneous TDC occupying most the retropharyngeal and mediastinal space. To our knowledge, this is the youngest patient to date presenting with TDC. Ultimately, his TDC was completely resolved with sclerotherapy, however the patient's age and size presented unique challenges to his medical management, which we describe below. PMID- 29447815 TI - Pre- and post-operative evaluation of the frequency of nocturnal enuresis and Modified Pediatric Epworth Scale in pediatric obstructive sleep apnea patients. AB - OBJECTIVE: To investigate the beneficial effect of adenotonsillectomy (AT) on nocturnal enuresis (NE) in children with adenotonsillar hypertrophy and evaluate the Modified Pediatric Epworth Scale (MPES). METHODS: This was a prospective study comparing preoperative and postoperative evaluation of the frequency of NE and MPES in pediatric obstructive sleep apnea (OSA). A questionnaire on NE history was prepared based on the Turkish Enuresis Guidelines. NE histories were evaluated pre- and postoperatively on the first month and third month, respectively. MPES questions were asked to the parents of all the OSA patients pre- and postoperatively, and scores were noted. RESULTS: Eighty-four (84) pediatric OSA patients were involved in the study. Preoperatively, 19 patients (27%) complained about nocturnal enuresis. After the surgery, 52% of the patients with NE had complete resolution of NE (p < 0.001). Postoperatively, the average Epworth scores of both groups significantly decreased (p < 0.001). CONCLUSION: There is a strong correlation between OSA and NE. In the present study, enuresis in pediatric OSA patients significantly decreased after surgery. Also, Epworth scores decreased significantly after surgery. In children with nocturnal enuresis, the presence of OSA symptoms should be questioned. PMID- 29447816 TI - Cochlear implant symmetry via template. AB - Current trends in bilateral cochlear implantation (CI) favor a minimally invasive subperiosteal pocket technique. Symmetric receiver-stimulator (R/S) placement is an important goal for bilateral CI, especially with regard to patient satisfaction. In this article, we describe a method easily adopted to achieve optimal symmetry. Upon reviewing the Senior Author's 11 bilateral CI cases using the direct subperiosteal pocket technique with the proposed "mirror template," we found improved symmetry, which translated into high patient and family satisfaction regarding the aesthetics of the symmetric R/S placement. PMID- 29447817 TI - Mature and immature pediatric head and neck teratomas: A 15-year review at a large tertiary center. AB - INTRODUCTION: Pediatric head and neck teratomas account for less than 4% of congenital teratomas. The distinct presentations and outcomes of mature and immature head and neck teratomas have not been well established. OBJECTIVES: To review the management and outcomes of pediatric head and neck teratomas. To distinguish differences between mature and immature tumors with respect to the age at presentation and surgery, tumor size and location, alpha fetoprotein (AFP) levels, airway management, and recurrence. METHODS: A 15-year retrospective chart review of patients treated for head and neck teratomas at Texas Children's Hospital was performed. A total of 20 patients were included. Wilcoxon rank and Fisher's exact tests were used for statistical analysis. RESULTS: Immature teratomas were associated with both higher AFP levels (80800 ng/ml, p = 0.02) and maximum tumor dimensions (14.4 cm, p = 0.0034) than mature teratomas (24400 ng/ml and 6.44 cm). Patients with immature tumors were younger at the time of surgical resection (19.8 days, p = 0.025) compared to those with mature tumors (348 days). 89% of immature teratomas involved anterior neck localization compared to 27% for mature teratomas (p = 0.0098); 88% of the immature teratomas required an EXIT (Ex Utero Intrapartum Treatment) procedure compared with 40% of the mature teratomas (p = 0.0656). Recurrence was noted in only two cases: an immature teratoma 51 months after incomplete resection and a mature teratoma 33 months after complete resection. Long-term consequences of surgical resection included cleft palate (38.9%), dysphagia (33.3%), facial nerve paresis/paralysis (16.7%) and tracheotomy (16.7%). CONCLUSION: Immature teratomas had higher AFP levels, tumor dimensions, frequency of anterior neck localization, and requirement of EXIT than mature teratomas. Given that there was no significant difference between the recurrence rates of immature and mature teratomas, follow-up vigilance should be maintained equally regardless of tumor maturity. PMID- 29447818 TI - Sirolimus for management of complex vascular anomalies - A proposed dosing regimen for very young infants. AB - Neonates with vascular anomalies causing airway compromise and other complications require early initiation of medical therapy. Sirolimus has emerged as a safe and effective treatment, but standard recommendations for dosing start at seven months. Guidelines are needed for dosing in very young infants, who have reduced hepatic metabolism of sirolimus. We present our experience treating six neonates (mean age 14.8 days) with complicated vascular anomalies. Standard dosing caused supratherapeutic levels in this population. Our modified dosing regimen has resulted in safe therapeutic concentrations. Properly dosed, sirolimus is a viable and potentially lifesaving option for neonates with severe morbidity from vascular anomalies. PMID- 29447819 TI - Lingual tonsillectomy in children with Down syndrome: Is it safe? AB - OBJECTIVE: Evaluate peri-operative course and morbidity in children with Down syndrome (DS) who underwent a lingual tonsillectomy (LT) for residual obstructive sleep apnea (rOSA). METHODS: Retrospective case series for children with DS who underwent LT for rOSA from April 2011 to July 2016. Our primary outcomes were length of stay, readmission and complications. Surgical effectiveness was evaluated by change in the obstructive apnea-hypopnea-index(OAHI) and oxygen saturation nadir. RESULTS: Thirty-nine patients underwent LT. The mean length of stay was 1.3 days with n = 21(72%) staying one night. One subject (2.6%) had a post-operative bleed that did not require operative intervention. No other major complications occurred. In terms of effectiveness of surgery, twenty-nine children had sufficient data for inclusion. Median OAHI did not appreciably change (p = 0.07) from before surgery. Five subjects (17%) were cured of OSA (OAHI < 2/hour) and a mix of improvement and worsening was identified. The lowest oxygen saturation improved from 78% (SD = 7) before surgery to 82% (SD = 6) after surgery (p = 0.003). CONCLUSION: LT has a favorable post-operative course but its effectiveness at curing rOSA in the DS population has not been established/proven. Further research is indicated to determine optimal surgical management for DS children with LTH. LEVEL OF EVIDENCE: 4. PMID- 29447820 TI - How does a bilingual environment affect the results in children with cochlear implants compared to monolingual-matched children? An Italian follow-up study. AB - OBJECTIVES: To compare the results after cochlear implantation achieved by monolingual and bilingual deaf children implanted at our Institution, with the aim of understanding if there are any differences between the two groups and if there is a correlation between the outcomes and some patients' variables. METHODS: The study group was composed by 14 bilingual deaf children and the control group by the same number of monolingual children implanted at our Institution. The control group was obtained by matching to each bilingual child a monolingual one with a similar clinical history regarding age at hearing loss diagnosis, age at first hearing-aids fitting and age at CI procedure. Children received a speech perception and linguistic development evaluation through specific structured tests. The linguistic competence of the patients both in mainstream and native language was determined by the Student Oral Language Observation Matrix (SOLOM). RESULTS: We did not find any statistically significant differences between bilingual and monolingual children in speech perception outcomes. Nevertheless, we obtained different results concerning language skills: bilingual implanted children scored lower at structured language tests, even if the difference was not statistically relevant. Bilingual children scored significantly lower than monolingual ones at the SOLOM scale for linguistic competence. CONCLUSION: The results reported in the present study show better language skills after cochlear implant in Italian monolingual cases than in bilingual ones. This seems to be related to the condition of bilingualism in Italy, mainly related to immigration, and frequently associated with low socio economic levels, poor competence in the mainstream language and poor social integration, with a suboptimal exposure to the mainstream language and difficulties in following the rehabilitative program. PMID- 29447821 TI - Genetic analysis of CLDN14 in the Chinese population affected with non-syndromic hearing loss. AB - OBJECTIVE: The CLDN14 gene, encoding the tight junction protein Claudin-14, has been proposed as a candidate causative gene affecting autosomal recessive non syndromic hearing loss (ARNSHL). Genetic analysis of nonsynonymous single nucleotide variations (nsSNVs) in CLDN14 has been performed in different populations. The role of CLDN14 nsSNVs in contributing to hearing loss in Chinese populations would be investigated in this study. METHODS: Target screening for CLDN14 variations were conducted in 500 unrelated patients diagnosed with non syndromic hearing loss (NSHL). RESULTS: No reported pathogenic CLDN14 nsSNVs in heterozygote or homozygote were detected in this study, however, we identified 4 heterozygous nsSNVs [c.11C > T, p.(Thr4Met); c.16G > A, p.(Val6Met); c.68T > C, p.(Ile23Thr); c.367A > C, p.(Thr123Pro)] in CLDN14. The 4 nsSNVs are located at claudin-14 transmembrane domains, but assessed to be poorly conservative and non pathogenic via multiple in silico algorithms. The structure-based analysis also suggested that the 4 nsSNVs had less structural and functional impact on claudin 14. CONCLUSION: Our findings indicated that CLDN14 might not be a major causative gene for NSHL in Chinese populations, which would contribute to fully understanding the genetic cause of NSHL in the East Asian populations. PMID- 29447822 TI - Are validated patient-reported outcomes used on children in pediatric otolaryngology? A systematic review. AB - OBJECTIVES: Review the pediatric otolaryngology literature to 1) identify studies in which children completed patient-reported outcome (PRO) measures and 2) appraise the psychometric quality and validity of these PROs as they apply to pediatrics. METHODS: In October 2016, a systematic review was performed by two reviewers on PubMed/MEDLINE and EMBASE for all otolaryngology-related studies that utilized PROs in children. Inclusion criteria included articles that required children (age<18) to complete PROs. Exclusion criteria included validation studies, reviews, and abstracts. Interreviewer agreement was determined using Cohen's kappa. Quality and rigor of validation testing for included PROs was determined using the COnsensus-based Standards for selection of health status Measurement Instruments. RESULTS: Interrater agreement was very good (kappa = 0.91; 95% CI, 0.85-0.98). Out of 316 articles retrieved, 11 met inclusion criteria. Eight PROs were identified. Six PROs were tested for validity and three of these PROs were tested for validity specifically within children. The most frequently utilized PRO was the Pediatric Rhinoconjunctivitis Quality of Life Questionnaire. Two studies (18.2%) utilized PROs within the scope of their validation. Seven studies (63.6%) used PROs outside the scope of their validation. Two studies (18.2%) used non-validated PROs. CONCLUSIONS: Patient reported outcomes have become an integral part of research and quality improvement. There is a relative paucity of PROs directed towards children in pediatric otolaryngology and some studies utilized PROs that were not validated or not validated for use in this age group. Future efforts to design and validate more instruments may be warranted. PMID- 29447823 TI - EXIT (ex utero intrapartum treatment) in a growth restricted fetus with tracheal atresia. AB - Congenital high airway obstruction syndrome (CHAOS) encompasses a heterogeneous group of pathologies leading to poor lung development and difficulty oxygenating the newborn after delivery. While previously uniformly fatal, the ex utero intrapartum therapy (EXIT) procedure has provided a method to treat these patients and provide an airway to potentiate survival. We present a patient diagnosed prenatally with CHAOS secondary to tracheal atresia complicated by severe intra-uterine growth restriction (IUGR) who was successfully delivered via an EXIT procedure at 33-weeks. Multidisciplinary care and planning is paramount. PMID- 29447824 TI - Central xanthoma of the mandible associated with hyperlipidemia: A rare presentation. AB - Xanthoma is a common, self-limiting cutaneous lesion of non-Langerhans cell, lipid-laden foamy histiocytes that is often concomitant with hyperlipidemia. The intraosseous counterpart is rarely encountered and typically presents as a painless, expansile osteolytic process in the context of hyperlipidemia or normolipidemia. Only a scant number of gnathic xanthomas have been reported in the otolaryngologic literature. We report the clinical, laboratory, radiographic, histopathologic, immunohistochemical, and ultrastructural studies of a mandibular lesion discovered in an asymptomatic 16-year-old male, and associated with 2 previously unreported comorbidities, namely hyperlipidemia and vitamin D deficiency. PMID- 29447825 TI - Profilactic role of simvastatin and mitomycin C in tracheal stenosis after tracheal damage: Study in rats. AB - OBJECTIVES: We aimed to investigate the prophylactic effect simvastatin of and mitomycin C (MMC) on laryngeal and tracheal stenosis in tracheotomised rats by histopathological evaluation of laryngotracheal segment. Randomized prospective single-blind. MATERIAL AND METHOD: Standard vertical tracheotomy was performed on 24 rats. Then the animals were randomly divided into three groups as A, B and C. In group A 0.4 mg/day once daily mitomycin C was injected to the paratracheal region for 14 days. In group B daily 30 mg/kg/day simvastatin was given via gavage to rats for 14 days. In group C 2 cc/day intraperitoneal saline given to rats and the created control group by 14 days follow up. After 10 days, tracheal cannulas were removed. Three weeks later, all animals were euthanized and trachea specimens were harvested. The present study investigates the effects of MMC and Simvastatin on fibrosis, inflammation, stenosis index and tracheal wall thickness in a tracheal injury model. RESULTS: The difference between the groups in terms of degree of inflammation scores was statistically insignificant (P = 0,187). Differences between the groups were found to be insignificant in terms of the preventionof fibrosis (P = 0,993). There was no significant difference between groups in terms of stenosis index (P = 0.645). In terms of wall thickness, control, simvastatin and mitomycin C groups were statistically different (p = 0.038). The difference between post-hoc test results was between Mitomycin C and control groups (p = 0.036). Maximum wall thickness in the MMC group (0,299 mm) was significantly lower compared to the control group (0,382 mm)(P < 0,0001). Maximum wall thickness was statistically lower in the simvastatin (0.324 mm) group compared with the control group (0.382 mm) (P < 0.0001). There was no statistically significant difference between the simvastatin group (0,198 mm) and control group (0,200 mm) with respect to minimum wall thickness (P = 0.982). Minimum wall thickness was significantly lower in the mitomycin-C group (0,160 mm) comparison to the control group (0,200 mm) (P < 0.0001). CONCLUSION: It was detected that the simvastatin and MMC is not effective in preventing the tracheal stenosis, inflammation and fibrosis formation. PMID- 29447826 TI - Impact of age on the anatomy of the pediatric pterygopalatine fossa and its relationship to the suprazygomatic maxillary nerve block. AB - OBJECTIVES: The suprazygomatic maxillary nerve block is associated with improved post-operative pain management after select craniofacial surgical procedures. This study's objective is to better define the impact of pediatric facial skeletal growth on techniques for accessing the pterygopalatine fossa (PPF). METHODS: Pediatric patients with prior thin-slice maxillofacial computed tomography imaging were identified in an institutional radiology database. Aquarius image-processing software (Ver. 4.4.11, TeraRecon, Inc., Foster City, CA) was used to measure from the suprazygomatic skin to the greater wing of the sphenoid where the needle is then re-oriented in an anterior and inferior trajectory allowing it to advance into the PPF. RESULTS: A total of 90 patients ranging from 0 to <=18 years of age were included in the study. The mean distance from the suprazygomatic skin to the foramen rotundum in patients 0 to <=12 months of age and >13 to <=18 years of age was 38.6 (SD +/- 4.7) and 47.1 (SD +/- 3.2) mm, respectively (p < .0001). The statistical analysis demonstrated a positive correlation between age in years and all of the measured distances (p = .0001). With respect to the plane of the needle entry site, the anterior and inferior angles required for passage into the PPF in the 0 to <=12 months age group were 11 (SD +/- 2.1) and 9.0 (SD +/- 2.5) degrees, respectively, compared to those in the >13 to <=18 years of age group at 12.4 (SD +/- 1.9) and 12.1 (SD +/- 3.2) degrees, respectively. These data reveal that patients in the oldest compared to the youngest pediatric age groups require significantly greater needle insertion, yet the angles of needle re-orientation are clinically similar between these two pediatric age groups varying by up to only 3 degrees . CONCLUSION: As expected, the distance from the skin to the foramen rotundum increases significantly with age; however, the angles of re-orientation with respect to the original needle entry site demonstrated up to only 3 degrees of variability between the youngest and oldest age groups evaluated in this pediatric cohort. PMID- 29447827 TI - A novel approach for comparing patterns of foreign body injuries across countries: A case study comparing European Countries and Bosnia and Herzegovina. AB - OBJECTIVES: The present study aimed at analyzing the characteristics of FB injuries from Bosnia and Herzegovina (B&H), a rapidly growing newly industrialized country, and to compare them with cases from European countries. METHODS: The analysis is based on FB injury cases included in the Susy Safe registry. Cases from the Ear-Nose-Throat (ENT) Clinic, University Clinical Center of Tuzla (B&H) were compared with cases from European countries participating in the Susy Safe project. Multiple Correspondence Analysis (MCA) was performed to elucidate differences within a large data set regarding mechanisms and objects causing injuries. RESULTS: The results of the MCA showed that the first three dimensions explained 43% of the variability. The first dimension was identified by children hospitalized for FB ingestion, the second one by children hospitalized for FB aspiration (lower airways), and the third one by children with an FB in the ear or in the upper airways. The analysis of the median of coordinates of factors contributing to each dimension showed that the greatest difference between B&H and European countries regarded the third one. Looking at the profile of these patients, it might be suggested that the proportion of males and females and the type of activity in which they were involved at time of injury occurrence are different among the countries considered CONCLUSIONS: This study proposes a simple tool for assessing differences among countries in the distribution of FB injuries. This case study shows that B&H has different patterns of FB injuries in the upper respiratory tract. PMID- 29447828 TI - Validity of automated threshold audiometry in school aged children. AB - BACKGROUND: Automated hearing tests have the potential to reduce the burden of disease amongst learners by introducing such services within the school context. METHODS: The aim of the study was to conduct a validation study on normal and hearing impaired learners, comparing air and bone conduction automated test results to conventional test results in 50 school aged learners (n = 100 ears) within a noise controlled school environment using a cross sectional comparative study design. The KuduWave 5000 (Emoyo.net) was used in this study. DATA ANALYSIS: The spearman's correlation coefficient was calculated to determine test retest reliability. The mean and standard deviation (SD) was measured for each frequency. The absolute mean difference (AMD) and SD was calculated for both air and bone conduction testing at each frequency for automated testing. A paired sampled t-test and a one way ANOVA was used to identify any significant differences. Alpha was set as 0.05. RESULTS: There was significant correlation between thresholds obtained for automated test one and test two for normal hearing and hearing impaired group. The spearmans correlation coefficient was high (close to +1) for majority of the results for both groups across the frequency range. Both air and bone conduction testing across the frequency range of 250 Hz-2000 Hz and at 8000 Hz were not statistically signfiicant (p < .005) for both groups, however at 4000 Hz for bone conduction testing in the hearing impaired group, there was a statisticially signficant difference (p = .003). This was attirubted to the variaibilty in bone conduction test results often due to force and placement of the bone vibrator. CONCLUSION: The findings indicate that automated audiometry can yield relaible results that are comparable to conventional test results. Key clinical considerations include extending the response time, regular rest periods, improving instructions and comfort levels. PMID- 29447829 TI - Custom-Made Titanium Miniplates Associated With Ultrahigh-Molecular-Weight Polyethylene Graft in Orthognathic Surgery: An Adjunct to Maxillary Advancement. AB - Patients with considerable maxillomandibular anteroposterior discrepancies and maxillary hypoplasia require corrective treatment through orthognathic surgery. However, in the treatment of severe maxillary retrognathism, it is necessary to reconstruct areas of bone deficiency through grafting techniques in addition to maxillary advancement using only the Le Fort I osteotomy. Treatment in these patients is more challenging and requires high surgical predictability. Alloplastic materials often have been used for the reconstruction of poor bone contours. Ultrahigh-molecular-weight polyethylene (UHMWPE) is currently an excellent filler material for poor bone regions and is a good substitute for autografts and other alloplastic materials for its unique properties, including high biocompatibility. Insertion of this material in the fixation system customized for virtually planned orthognathic surgeries is an innovative technique. This report describes the insertion of UHMWPE into custom-made titanium miniplates manufactured by computer-aided design and computer-aided manufacturing technology for orthognathic surgery consisting of maxillary advancement and mandibular retrusion to treat a patient with Crouzon syndrome, Class III malocclusion, and severe maxillary retrognathism.

Maintenance of the airway and difficulty in feeding are the main concerns for such patients. We performed a PubMed search to identify reported cases of syngnathia. With reference to the site of fusion and corresponding anomalies, the available studies were reviewed. The maxillomandibular fusion can be anterior fusion, unilateral or bilateral fusion, and complete fusion. The condition can be an isolated problem or associated with a syndrome. The condition requires immediate attention because it can be fatal. A case of isolated unilateral syngnathia, with the detailed review of the published data, is reported. PMID- 29447831 TI - Rhabdomyolysis After Prolonged Surgery: Report of 2 Cases and Review of Literature. AB - Rhabdomyolysis is a condition in which damaged muscle tissue breaks down and intracellular contents, including myoglobin, are released into the circulation. This produces a nonspecific clinical syndrome including electrolyte disturbances, hypovolemia, metabolic acidosis, coagulopathies, and risk of acute kidney injury. Rhabdomyolysis has been reported as a complication of prolonged surgical procedures but has rarely been reported in the oral and maxillofacial surgery literature. Early diagnosis and treatment of rhabdomyolysis are important to avoid long-term complications such as renal failure. We present 2 cases of postoperative rhabdomyolysis after prolonged maxillofacial surgical procedures in which the patients were managed without long-term sequelae. The pathophysiology, risk factors, diagnosis, and treatment of postoperative rhabdomyolysis are discussed, with a brief review of the literature.

AB - OBJECTIVE: To assess the impact of an intervention for teenage mothers with the involvement of maternal grandmothers on the prevalence of pacifier use in the first six months of life. METHODS: This randomized clinical trial involved 323 teenage mothers, allocated to four groups: intervention with teenagers only, intervention with teenagers and their mothers, and respective controls. Six breastfeeding counseling sessions, including the recommendation to avoid the use of a pacifier, were delivered at the maternity ward and subsequently at the teenagers' homes, at seven, 15, 30, 60, and 120 days postpartum. Data on infant feeding and pacifier use were collected monthly by interviewers blinded to group allocation. The impact of the intervention was measured by comparing survival curves for pacifier use in the first six months of life and mean time to pacifier introduction. RESULTS: The intervention had a significant impact on reducing pacifier use only in the group in which grandmothers were involved. In this group, the intervention delayed by 64 days the introduction of a pacifier (21-85 days), compared to 25 days in the group without the participation of grandmothers (65-90 days). CONCLUSIONS: The intervention reduced pacifier use in the first six months of life and delayed its introduction until beyond the first month when grandmothers were involved. The intervention did not have a significant impact when only teenage mothers were involved. PMID- 29447833 TI - Editorial Comment. PMID- 29447834 TI - Reply by Authors. PMID- 29447835 TI - Clay eating attenuates lithium-based taste aversion learning in rats: A remedial effect of kaolin on nausea. AB - Kaolin clay eating has been considered as a marker of nausea in rats, because a variety of treatments, which evoke nausea in humans, generate consumption of kaolin clay in rats. The present study with two experiments replicated kaolin clay ingestion induced by an injection of emetic lithium chloride (LiCl). The LiCl injection, however, did not generate eating of wooden objects in rats. The present study also provides a new finding that consumption of kaolin clay alleviates rats' taste aversion learning caused by an LiCl injection. This finding is congruent with the contention that consumption of kaolin clay is not only a useful index of, but also an effective remedy for, drug-induced nausea in rats. PMID- 29447836 TI - Sensory denervation of inguinal white fat modifies sympathetic outflow to white and brown fat in Siberian hamsters. AB - White adipose tissue (WAT) and brown adipose tissue (BAT) have sympathetic nervous system (SNS) and sensory innervations. Previous studies from our laboratory revealed central neuroanatomical evidence of WAT sensory and BAT SNS crosstalk with double labeling of inguinal WAT (IWAT) sensory and interscapular BAT (IBAT) SNS neurons. We previously demonstrated that WAT lipolysis increases IBAT temperature, but this effect is absent when IWAT afferents are surgically denervated, which severs both sensory and SNS nerves. It is possible that WAT sensory feedback can regulate SNS drive to itself and other WAT and BAT depots, and thus contribute to the existence of differential SNS outflow to fat during different energy challenges. Here we selectively denervated IWAT sensory nerves in Siberian hamsters using capsaicin and measured norepinephrine turnover (NETO) i.e., SNS drive to WAT and BAT depots, IBAT uncoupling protein 1 (UCP1) expression, body mass, fat mass, blood glucose, and food consumed after a 24-h cold exposure. IWAT sensory denervation decreased both IWAT and IBAT NETO and IBAT UCP1 expression. IWAT sensory denervation, however, increased mesenteric WAT (MWAT) NETO after the 24-h cold exposure and did not modify epididymal WAT (EWAT) and retroperitoneal WAT (RWAT) NETO compared with respective controls. Body mass, fat mass, blood glucose, and food consumed were unchanged across groups. RWAT and EWAT mass decreased in capsaicin-injected hamsters, but did not in the vehicle hamsters. These results functionally demonstrate the existence of IWAT sensory and IBAT SNS crosstalk and that a disruption in this sensory-SNS feedback mechanism modifies SNS drive to IWAT, IBAT, and MWAT, but not EWAT and RWAT.

AB - Osmoregulation mechanism underlying acclimation and adaptation of migratory fish to different salinities has been studied for decades. Recently developed transcriptomic and proteomic techniques would make it possible to provide more reliable data to decipher the mechanism study at a molecular level. Here in this study, an integrative analysis of the kidney-specific transcriptome and proteome was performed to identify important regulators and pathways involved in salinity adaption of roughskin sculpin (Trachidermus fasciatus). Fish were subjected to seawater-to-freshwater transfer that was achieved in 24 h, samples were collected at 12, 24 and 48 h after the start of the experiment. Time course profiling of gene and protein expressions were examined using RNA-seq and iTRAQ methods. A total of 1504 differentially expressed genes (DEGs) and 378 differentially expressed proteins (DEPs) were identified at the three time points. 66 proteins were filtered by correlation of transcriptome and proteome results. When comparing the data obtained from the three time points, 12 h exhibited the largest number of DEGs and DEPs, suggesting the time course experiment is critical to clarify the framework of regulatory genes/proteins in response to salinity change. This study provides the first time-course, kidney-specific, combined transcriptomic and proteomic profiling associated with salinity adaption of Trachidermus fasciatus. The results revealed the possibility of T. fasciatus as an experimental animal for osmoregulation studies, showed the powerfulness of combining transcriptomic and proteomic approaches to provide molecular insights of osmoregulation mechanisms in migratory fish.

AB - We propose a model for the growth of microbial populations in the presence of a rate-limiting nutrient which accounts for the switching of cells to a dormant phase at low densities in response to decreasing concentration of a putative biochemical signal. We then show that in conditions of nutrient starvation, self sustained oscillations can occur, thus providing a natural explanation for such phenomena as plankton blooms. However, unlike results of previous studies, the microbial population minima do not become unrealistically small, being buffered during minima by an increased dormant phase population. We also show that this allows microbes to survive in extreme environments for very long periods, consistent with observation. The mechanism provides a natural vehicle for other such sporadic outbreaks, such as viral epidemics. PMID- 29447839 TI - Consensus statement on the need for innovation, transition and implementation of developmental neurotoxicity (DNT) testing for regulatory purposes. AB - This consensus statement voices the agreement of scientific stakeholders from regulatory agencies, academia and industry that a new framework needs adopting for assessment of chemicals with the potential to disrupt brain development. An increased prevalence of neurodevelopmental disorders in children has been observed that cannot solely be explained by genetics and recently pre- and postnatal exposure to environmental chemicals has been suspected as a causal factor. There is only very limited information on neurodevelopmental toxicity, leaving thousands of chemicals, that are present in the environment, with high uncertainty concerning their developmental neurotoxicity (DNT) potential. Closing this data gap with the current test guideline approach is not feasible, because the in vivo bioassays are far too resource-intensive concerning time, money and number of animals. A variety of in vitro methods are now available, that have the potential to close this data gap by permitting mode-of-action-based DNT testing employing human stem cells-derived neuronal/glial models. In vitro DNT data together with in silico approaches will in the future allow development of predictive models for DNT effects. The ultimate application goals of these new approach methods for DNT testing are their usage for different regulatory purposes. PMID- 29447841 TI - CRISPR/Cas9 generated human CD46, CD55 and CD59 knockout cell lines as a tool for complement research. AB - BACKGROUND: To prevent unwanted complement activation and subsequent damage, complement activation must be tightly regulated on healthy host cells. Dysregulation of the complement system contributes to the pathology of diseases like Paroxysmal Nocturnal Hemoglobinuria and atypical Hemolytic Uremic Syndrome. To investigate complement regulator deficiencies, primary patient cells may be used, but access to patient cells may be limited and cells are heterogeneous between different patients. To inhibit regulator function on healthy host cells, blocking antibodies can be used, though it may be difficult to exclude antibody mediated effects. To circumvent these issues, we created single and combined complement regulator human knockout cells to be able to in vitro investigate complement activation and regulation on human cells. METHODS: CRISPR/Cas9 was used to knockout (KO) complement regulatory proteins CD46, CD55 and/or CD59 in human HAP1 cells. Single cell derived cell lines were profiled by Sanger sequencing and flow cytometry. To confirm the lack of complement regulatory function, the cells were exposed to complement in normal human serum and subsequently C3 and C4 deposition on the cell surface were detected by using flow cytometry. RESULTS: We created single KO cell lines that completely lacked CD46, CD55 or CD59. We additionally generated double CD46/CD55, CD46/CD59 and CD55/CD59 KOs and triple CD46/CD55/CD59 KOs. Upon classical pathway activation, deletion of CD46 resulted in increased C3 and C4 deposition, while deleting CD55 mainly resulted to increased C3 deposition, confirming their reported function in complement regulation. Upon alternative pathway activation, C3 deposition was only observed on the triple CD46/CD55/CD59 KO cells and not on any of the other cell lines, suggesting that human cells are resistant to spontaneous complement activation and suggesting a role for CD59 in C3 regulation. CONCLUSIONS: The generation of complement regulator KO cell lines provides a relevant tool for future in vitro investigations of complement activation and regulation on human cells. Furthermore, these cell lines may also be helpful to evaluate therapeutic complement inhibitors and may shed light on novel roles of complement regulatory proteins as we here observed for CD59. PMID- 29447843 TI - Creativity and cognitive control: Behavioral and ERP evidence that divergent thinking, but not real-life creative achievement, relates to better cognitive control. AB - Two studies used event-related potentials (ERPs) to examine whether and how divergent thinking and creative achievement are linked to attentional flexibility and cognitive control as indexed by response times and by the amplitude of the anterior N2 ERP component. Both experiments used an oddball paradigm in which participants viewed hierarchical letter stimuli and identified target letters in frequent and rare target trials. The successful identification of targets required attentional flexibility when switching levels of attention (from the frequent global to the rare local attentional level, or vice-versa). Divergent thinkers showed smaller switching times on rare target trials, indicating higher levels of attentional flexibility. Furthermore, divergent thinkers engaged cognitive control processes more strongly at the moment of the attentional switch (and before the response), as indicated by a larger N2 difference between frequent and rare targets. In contrast, creative achievement was associated neither with the switching times on rare target trials, nor with a larger N2 difference between frequent and rare targets. All results held when controlling for general intelligence. Results from these studies provide evidence that divergent thinking is associated with higher attentional flexibility and that such attentional flexibility relies on cognitive control processes required when disengaging from one level of attention (e.g., global), and shifting to the other level of attention (e.g., local). PMID- 29447842 TI - Neutrophils drive type I interferon production and autoantibodies in patients with Wiskott-Aldrich syndrome. AB - BACKGROUND: Wiskott-Aldrich syndrome (WAS) is a rare primary immunodeficiency caused by mutations in Wiskott-Aldrich syndrome protein (WASp), a key regulator of cytoskeletal dynamics in hematopoietic cells. A high proportion of patients experience autoimmunity caused by a breakdown in T- and B-cell tolerance. Moreover, excessive production of type I interferon (IFN-I) by plasmacytoid dendritic cells (pDCs) contributes to autoimmune signs; however, the factors that trigger excessive innate activation have not been defined. OBJECTIVE: Neutrophil extracellular traps (NETs) emerged as major initiating factors in patients with diseases such as systemic lupus erythematosus and rheumatoid arthritis. In this study we explored the possible involvement of aberrant neutrophil functions in patients with WAS. METHODS: We evaluated the expression of a set of granulocyte genes associated with NETs in a cohort of patients with WAS and the presence of NET inducers in sera. Using a mouse model of WAS, we analyzed NET release by WASp null neutrophils and evaluated the composition and homeostasis of neutrophils in vivo. By using depletion experiments, we assessed the effect of neutrophils in promoting inflammation and reactivity against autoantigens. RESULTS: Transcripts of genes encoding neutrophil enzymes and antimicrobial peptides were increased in granulocytes of patients with WAS, and serum-soluble factors triggered NET release. WASp-null neutrophils showed increased spontaneous NETosis, induced IFN I production by pDCs, and activated B cells through B-cell activating factor. Consistently, their depletion abolished constitutive pDC activation, normalized circulating IFN-I levels, and, importantly, abolished production of autoantibodies directed against double-stranded DNA, nucleosomes, and myeloperoxidase. CONCLUSIONS: These findings reveal that neutrophils are involved in the pathogenic loop that causes excessive activation of innate cells and autoreactive B cells, thus identifying novel mechanisms that contribute to the autoimmunity of WAS. PMID- 29447844 TI - Angiotensin II facilitates GABAergic neurotransmission at postsynaptic sites in rat amygdala neurons. AB - The central nucleus of the amygdala (CeA) is critical in the regulation of sodium appetite. Angiotensin II (Ang II) is important in the generation of sodium appetite and may function as a neurotransmitter or modulator to affect the synaptic transmission and the excitability of neurons. However, the role of Ang II in the CeA remains unclear. In this study, we determined the effects of Ang II on the excitatory and inhibitory synaptic inputs to the CeA neurons in brain slices with whole-cell patch-clamp recordings. Ang II (0.5-5 MUM) significantly potentiated the amplitude of spontaneous GABAergic inhibitory postsynaptic currents (IPSCs) in a concentration-dependent manner. Ang II (2 MUM) significantly increased the amplitude of miniature GABAergic inhibitory postsynaptic currents (mIPSCs) without affecting the frequency. This effect was blocked by Ang II type 1 (AT1) receptor antagonist, losartan. One mM guanosine 5' O-(-2-thiodiphosphate) (GDP-beta-s) in the pipette internal solution eliminated the facilitatory effect of Ang II on GABAergic synaptic transmission. In contrast, Ang II had no effect on the spontaneous glutamatergic excitatory postsynaptic currents (EPSCs) and did not alter the frequency and amplitude of miniature EPSCs at concentrations that facilitated IPSCs. Furthermore, Ang II decreased the firing activity of CeA neurons, and this effect was abolished by losartan and GDP-beta-s. In addition, Ang II failed to inhibit CeA neurons in the presence of bicuculline. These data provide substantial new evidence that Ang II inhibits the CeA neurons by facilitation of GABAergic synaptic input efficacy through activation of postsynaptic AT1 receptors. PMID- 29447846 TI - Keeping cool: Kissing bugs avoid cannibalism by thermoregulating. AB - Kissing bugs possess a highly developed thermal sense and when starved, they attempt to bite any object which temperature is close to that of a warm-blooded host. At each feeding event, these insects take massive meals in just a few minutes. One could then expect fed-bugs being heated-up by the ingested warm blood and so becoming attractive to starved conspecifics. This is not however the case, arising the question about why cannibalism is very rare among these insects. Recently, the ability of thermoregulating during feeding has been demonstrated in Rhodnius prolixus. These bugs possess a countercurrent heat exchanger that cools down the ingested blood, before it reaches the abdomen. We hypothesise that avoiding thermal stress is not the only adaptive advantages of this mechanism, but could also help avoiding cannibalism. We tested this hypothesis by quantifying cannibalism by never-fed first-instar larvae on: (1) just-fed 5th instar bugs, (2) artificially heated just-fed bugs, (3) heated or (4) non-heated objects of the same size. In line with our hypothesis, non-heated just-fed bugs were not attacked by the 1st instar larvae, whereas heated bugs and object triggered biting behaviour in starved bugs, which performed either cleptohaematophagy or haemolymphagy on heated bugs. We conclude that cannibalism triggered by thermal stimuli has been one of the selection pressures that gave origin to thermoregulation during feeding on kissing bugs. PMID- 29447845 TI - Probing GABAA receptors with inhibitory neurosteroids. AB - gamma-aminobutyric acid type A receptors (GABAARs) are important components of the central nervous system and they are functionally tasked with controlling neuronal excitability. These receptors are subject to post-translational modification and also to modulation by endogenous regulators, such as the neurosteroids. These modulators can either potentiate or inhibit GABAAR function. Whilst the former class of neurosteroids are considered to bind to and act from the transmembrane domain of the receptor, the domains that are important for the inhibitory neurosteroids remain less clear. In this study, we systematically compare a panel of recombinant synaptic-type and extrasynaptic-type GABAARs expressed in heterologous cell systems for their sensitivity to inhibition by the classic inhibitory neurosteroid, pregnenolone sulphate. Generally, peak GABA current responses were inhibited less compared to steady-state currents, implicating the desensitised state in inhibition. Moreover, pregnenolone sulphate inhibition increased with GABA concentration, but showed minimal voltage dependence. There was no strong dependence of inhibition on receptor subunit composition, the exception being the rho1 receptor, which is markedly less sensitive. By using competition experiments with pregnenolone sulphate and the GABA channel blocker picrotoxinin, discrete binding sites are proposed. Furthermore, by assessing inhibition using site-directed mutagenesis and receptor chimeras comprising alpha, beta or gamma subunits with rho1 subunits, the receptor transmembrane domains are strongly implicated in mediating inhibition and most likely the binding location for pregnenolone sulphate in GABAARs.

PMID- 29447847 TI - Perinatal selective serotonin reuptake inhibitor (SSRI) effects on body weight at birth and beyond: A review of animal and human studies. AB - The long-term impact of selective serotonin reuptake inhibitor (SSRI) antidepressant treatment during pregnancy and postpartum on offspring outcomes is still not clear. Specifically, perinatal SSRI exposure may have long-term consequences for body weight and related health outcomes in the newborn period and beyond. This review focuses on the impact of perinatal SSRI exposure on weight using human and animal findings. The impact of maternal mood is also explored. We propose potential mechanisms for weight changes, including how early alterations in serotonin signaling may have implications for weight via changes in metabolism and motor development. As the majority of serotonin is in the gastrointestinal (GI) system we also speculate that perinatal SSRI exposure might alter the brain-gut relationship, via the microbiome, leading to changes in feeding behavior and weight. PMID- 29447848 TI - Effects of tablet formulation and subsequent film coating on the supersaturated dissolution behavior of amorphous solid dispersions. AB - The effects of tablet preparation and subsequent film coating with amorphous solid dispersion (ASD) particles that were composed of a drug with poor water solubility and hydrophilic polymers were investigated. ASD particles were prepared with a drug and vinylpyrrolidone-vinyl acetate copolymer (PVPVA) or polyvinylpyrrolidone (PVP) at a weight ratio of 1:1 or 1:2 using a melt extrusion technique. Tablets were prepared by conventional direct compression followed by pan coating. A mathematical model based on the Noyes-Whitney equation assuming that stable crystals precipitated at the changeable surface area of the solid liquid interface used to estimate drug dissolution kinetics in a non-sink dissolution condition. All the ASD particles showed a maximum dissolution concentration approximately ten times higher than that of the crystalline drug. The ASD particles with PVPVA showed higher precipitation rate with lower polymer ratio, while PVP did not precipitate within 960 min regardless of the polymer ratio, suggesting the ASD particles of 1:1 drug:PVPVA (ASD-1) were the most unstable among the ASD particles considered. The dissolution of a core tablet with ASD-1 showed less supersaturation and a much higher precipitation rate than those of ASD-1 particles. However, a film-coated tablet or core tablet with a trace amount of hydroxypropylmethylcellulose (HPMC) showed a similar dissolution profile to that of the ASD-1 particles, indicating HPMC had a remarkable precipitation inhibition effect. Overall, these results suggest that tablet preparation with ASD may adversely affect the maintenance of supersaturation; however, this effect can be mitigated by adding an appropriate precipitation inhibitor to the formulation. PMID- 29447849 TI - Three-dimensional arterial spin labeling imaging with a DANTE preparation pulse. AB - On arterial spin-labeled (ASL) images, areas of bright intravascular signal will appear when the post labeling delay time is shorter than arterial transit time. Vascular suppression (VS) schemes reduce artefactual bright signal by dephasing intravascular labeled spins. However, existing VS methods, such as Motion Sensitized Driven-Equilibrium (MSDE), decrease the uniformity of the signal intensity distribution and extend the echo time. The purpose of this study is to compare VS using a Delays Alternating with Nutation for Tailored Excitation (DANTE) preparation pulse, with MSDE for ASL imaging on a flow phantom and volunteer data. In the phantom study, the signal decay pattern of moving water was similar for both methods. In the volunteer study, the bright intravascular signal artifact was decreased by both methods. However right-left differences in signal intensity were smaller using DANTE-prepared ASL. The proposed DANTE prepared ASL sequence has a vessel suppression effect while maintaining a uniform signal intensity distribution. This study indicates that DANTE is a potentially useful method for vessel suppression in ASL imaging. PMID- 29447850 TI - Impact of baseline CO2 on Blood-Oxygenation-Level-Dependent MRI measurements of cerebrovascular reactivity and task-evoked signal activation. AB - Neurovascular coupling describes the cascade between neuronal activity and subsequent Blood-Oxygenation-Level-Dependent (BOLD) signal increase. Based on this premise, the correlation of this BOLD signal increase with a particular task, such as finger-tapping, is used to map neuronal activation. This signal increase may be dampened in brain areas exhibiting impaired cerebrovascular reactivity (BOLD-CVR), leading to false negative activation. Blood-oxygenation level-dependent (BOLD) cerebrovascular reactivity (CVR) has also been used to optimize task evoked BOLD signal changes. To measure BOLD-CVR, controlled BOLD CVR studies have commonly been performed using a preset isocapnic carbon dioxide (CO2; ~40 mmHg) baseline, independent of subjects' resting CO2. This arbitrary baseline, however, may influence BOLD-CVR measurements. We therefore performed BOLD-CVR, as well as BOLD fMRI during a controlled bilateral finger-tapping task in two groups of ten subjects: group A at subject's resting CO2 and group B at a preset isocapnic CO2 baseline (40 mmHg). Whole brain BOLD-CVR was significantly decreased for group B (group A 0.26 (SD 0.05) vs group B 0.16 (SD 0.05), p < 0.001). For the predefined hand area in the precentral cortex, BOLD-CVR and BOLD fMRI signal changes were significantly lower for group B (group A 0.20 (SD 0.04) vs group B 0.13 (SD 0.05), p < 0.01; 1.19 (SD 0.31) vs 0.62 (SD 0.37), p < 0.01).CO2 levels significantly influence both BOLD-CVR and BOLD fMRI measurements. Hence, for an accurate interpretation, baseline CO2 levels and BOLD CVR should be considered complementary to task evoked BOLD fMRI.

AB - Colour vision is often essential for animals. Fine discrimination of colours enhances the ability of animals to find food, predators, or mating partners. Using two colour variants of medaka (Oryzias latipes), which mate assortatively depending on visual cues (pale grey versus dark orange), we recently established red colour-blind strains by knocking out the red opsin (long-wavelength sensitive) genes and elucidated that the fish were indeed insensitive to red light. In the present study, we investigated the mate choice of these red-blind fish. The colour variants with normal colour vision strongly preferred to mate with their own strain. The red-blind ones also preferred their own strain; i.e. they still mated assortatively. However, their preference was significantly weaker than that of fish with normal colour vision. In other words, the red-blind fish showed increased sexual interest in the other colour variant. These results indicated that reduced sensitivity to red light also reduced their ability to discriminate colours. This empirical evidence directly demonstrates that a change in cone-opsin repertoire changes mating decision behaviours, which would affect gene flow and speciation processes between conspecific colour variants in nature, as suggested in other studies. PMID- 29447853 TI - A comparator-hypothesis account of biased contingency detection. AB - Our ability to detect statistical dependencies between different events in the environment is strongly biased by the number of coincidences between them. Even when there is no true covariation between a cue and an outcome, if the marginal probability of either of them is high, people tend to perceive some degree of statistical contingency between both events. The present paper explores the ability of the Comparator Hypothesis to explain the general pattern of results observed in this literature. Our simulations show that this model can account for the biasing effects of the marginal probabilities of cues and outcomes. Furthermore, the overall fit of the Comparator Hypothesis to a sample of experimental conditions from previous studies is comparable to that of the popular Rescorla-Wagner model. These results should encourage researchers to further explore and put to the test the predictions of the Comparator Hypothesis in the domain of biased contingency detection. PMID- 29447854 TI - Risk factors and associated complications for postoperative urinary retention after lumbar surgery for lumbar spinal stenosis. AB - BACKGROUND CONTEXT: Postoperative urinary retention (POUR) is a very common postoperative complication of all surgeries (5%-70%) that may lead to complications such as urinary tract infection (UTI), bladder overdistension, autonomic dysregulation, and increased postoperative length of stay (LOS). Within the field of spine surgery, the reported incidence rate of POUR is highly variable (5.6%-38%). Lack of clear stratification of surgical level, spinal pathology, and inadequate sample size are major limitations of available studies concerning POUR following spine surgery, which may lead to inconsistency in the incidence of POUR and the ability to model its occurrence and consequences. PURPOSE: This study examines the incidence, predictive factors, and complications of POUR in patients undergoing elective posterior lumbar decompression with or without fusion for lumbar stenosis to eliminate bias from studying procedures done in different anatomical regions and with different approaches. Additionally, this study intends to identify the consequences of POUR. STUDY DESIGN AND SETTING: A retrospective consecutive cohort analysis was performed to examine patients undergoing posterior lumbar decompression who did and did not develop POUR. PATIENT SAMPLE: All patients undergoing posterior lumbar decompression with or without fusion for lumbar stenosis with claudication from January 2014 through December 2015 at our institution were evaluated. Patients under the age of 18 and patients with spinal malignancies or infections were excluded. OUTCOME MEASURES: Physiological measures included identification of POUR by evidence of reinsertion of a Foley catheter, use of straight catheterization postoperatively, or by a clear medical diagnosis with pharmacologic treatment. Other physiological measures included identification of development of UTI, sepsis, acute kidney injury (AKI), surgical site infection (SSI), or readmission within 90 days after surgery, as well as LOS and discharge disposition. METHODS: The electronic medical record was searched for all patients meeting inclusion and exclusion criteria. Postoperative urinary retention was defined as reinsertion of a Foley catheter, use of straight catheterization postoperatively, or a clear medical diagnosis with pharmacologic treatment. Statistical analysis was performed in R statistical software package version 3.3.2. Multiple variable selection techniques were used to determine appropriate variables for regression models, and logistic models were fit to the development of POUR and postoperative complications, whereas a linear regression model was used for LOS. RESULTS: Data were collected on 1,592 consecutive patients. Among the sample population, the mean age at surgery was 67 (standard deviation 10.1) and 45% of patients were women. The incidence rate of POUR was 17.1% (273/1592). Increased age (odds ratio [OR]=1.04; 95% confidence interval [CI], 1.02-1.06; p<.001), benign prostatic hyperplasia (BPH) (OR=1.92; 95% CI, 1.32-2.78); p<.001), previous AKI (OR=3.29; 95% CI, 1.11-9.29; p=.025), and previous UTI (OR=1.69; 95% CI, 1.24-2.24; p<.001) significantly increased the probability of developing POUR. Factors including increased body mass index, coronary artery disease, congestive heart failure, diabetes mellitus, chronic obstructive pulmonary disease, tobacco use, and fusion were found to be non-significant and were excluded from the model. With respect to complications, POUR was found to be associated with development of UTI (OR=4.50; 95% CI, 3.14-6.45; p<.001), sepsis (OR=4.05; 95% CI, 1.16-13.55; p=.022), increased LOS (p<.001), increased likelihood to be discharged to a skilled nursing facility (SNF) (OR of discharge to home=0.44; 95% CI, 0.32-0.62; p<.001), and increased risk of readmission within 90 days of the index surgery (OR=1.60; 95% CI, 1.11-2.26; p=.009). Development of POUR did not increase the risk of developing AKI (OR=2.45; 95% CI, 0.93-6.30; p=.063) or a SSI (OR=1.09; 95% CI, 0.56-2.02; p=.79). CONCLUSIONS: Overall, POUR was a significant risk factor for the development of UTI, sepsis, increased LOS, discharge to a SNF, and readmission within 90 days. Surgeons and anesthesiologists should take preventative measures against POUR in individuals with increased age, BPH, AKI, and UTI within 90 days before surgery, as these factors were found to significantly increase the risk of POUR. PMID- 29447855 TI - RPA using a multiplexed cartridge for low cost point of care diagnostics in the field. AB - A point of care device utilising Lab-on-a-Chip technologies that is applicable for biological pathogens was designed, fabricated and tested showing sample in to answer out capabilities. The purpose of the design was to develop a cartridge with the capability to perform nucleic acid extraction and purification from a sample using a chitosan membrane at an acidic pH. Waste was stored within the cartridge with the use of sodium polyacrylate to solidify or gelate the sample in a single chamber. Nucleic acid elution was conducted using the RPA amplification reagents (alkaline pH). Passive valves were used to regulate the fluid flow and a multiplexer was designed to distribute the fluid into six microchambers for amplification reactions. Cartridges were produced using soft lithography of silicone from 3D printed moulds, bonded to glass substrates. The isothermal technique, RPA is employed for amplification. This paper shows the results from two separate experiments: the first using the RPA control nucleic acid, the second showing successful amplification from Chlamydia Trachomatis. Endpoint analysis conducted for the RPA analysis was gel electrophoresis that showed 143 base pair DNA was amplified successfully for positive samples whilst negative samples did not show amplification. End point analysis for Chlamydia Trachomatis samples was fluorescence detection that showed successful detection of 1 copy/MUL and 10 copies/MUL spiked in a MES buffer.

INTERVENTION: Laparoscopic sacrohysteropexy. Institutional Review Board ruled that approval was not required for this study. MEASUREMENTS AND MAIN RESULTS: Uterine prolapse is very rare condition, manifesting in an estimated 10 000 to 15 000 pregnancies [1]. The management plan must be individualized, and the obstetrician should aware of possible complications, such as preterm labor, high incidence of abortion, cervical ulceration, and cervical dystocia. In general, bedrest, good genital hygiene, and pessary use is recommended. Alternatively, in cases where conservative solutions have failed, laparoscopic surgery in the pregnant patient may be considered. To date, only 1 case of laparoscopic promontohysteropexy at 10th weeks of gestation was reported by Pirtea et al [2]. A 37-year-old woman, at 12 weeks and 3 days of gestation, with stage III pelvic organ prolapse was referred to our clinic. Conservative management with pessary failed. The patient underwent laparoscopic sacrohysteropexy after written informed consent form was obtained. In exploration, uterine manipulation was difficult because of softness and large size of the uterus. First, the sigmoid colon was suspended at the abdominal wall to gain an adequate surgical field. The promontorium was dissected and the parietal peritoneum incised on the right pelvic side wall after ureter visualization. A polypropylene mesh was fixed to the cervix at the level of the uterosacral ligaments. The other edge of the mesh was fixed at the level of the promontory using the Uplift device (Neomedic International, Barcelona, Spain). Then, the peritoneum was sutured to cover the mesh. The patient was discharged 2 days after surgery. At the examination the pelvic floor was detected to be normal. The patient delivered a healthy baby weighing 3030 g by cesarean section at 38 weeks of gestation. The position of the mesh was controlled during surgery. There was no peritoneal fold detected on the cervical part of mesh; however, no adhesion was observed. CONCLUSION: Laparoscopic sacrohysteropexy may be an alternative and safe approach, if conservative treatment fails, for pelvic organ prolapse during pregnancy.

However, whether this effect rely on acetylcholine is unknown. Here we investigated if 17beta estradiol (E2) would be able to recover ORM deficits in animals with decreased expression of the Vesicular Acetylcholine Transporter (VAChT KDHET). We found that E2 improved short-term ORM (STM) in VAChT KDHET male and in OVX female mutant mice. However, E2 did not recover long-term (LTM) ORM in both sexes. Next, we tested whether hippocampal ERs activation could also rescue STM in mutant mice. Our results showed that ERalpha seems to be both sufficient and necessary for STM consolidation in female VAChT KDHET. Differently, in male, both ERalpha and ERbeta activation recovered STM. In addition, we tested whether mRNA level of estrogen receptors (ER) is also sensitive to VAChT expression. Female mutant mice showed lower levels of ER alpha (ERalpha) mRNA in the hippocampus, while no differences in male were observed. Together, our results showed that under hypocholinergic function, E2 improve short-term object recognition in both male and female. Furthermore, we showed that changes in VAChT expression might potentially modulate hippocampal ERalpha expression in a sex-dependent-manner. PMID- 29447858 TI - Intrathecal Injection of scAAV9-hIGF1 Prolongs the Survival of ALS Model Mice by Inhibiting the NF-kB Pathway. AB - Amyotrophic lateral sclerosis (ALS) is a chronic, fatal neurodegenerative disorder characterized by the progressive loss of upper and lower motor neurons. Currently, there is no effective drug for ALS. Recent studies in ALS model mice have shown that insulin-like growth factor-1 (IGF1) may be a promising therapeutic drug. We demonstrate that self-complementary adeno-associated virus serum type 9 encoding the human IGF1 (scAAV9-hIGF1) could significantly postpone the onset and slow down the progression of the disease owning to inhibiting the NF-kappaB signaling pathway. Furthermore, the results were supported by experiments in which the CRISPR/Cas9 system was used to knock-down IGF1 in ALS mice (mIGF1). Our data indicate that IGF1-mediated suppression of NF-kappaB activation in microglia is a novel molecular mechanism underlying MN death in ALS. It provides new insight into IGF1 and points toward novel therapeutic targets of IGF1 in ALS. PMID- 29447859 TI - Man With Bumps on His Shin. PMID- 29447860 TI - Man With Chest Pain and Lump in Neck.

AB - INTRODUCTION: Otitis media is the primary cause of antibiotic prescription in children. Two-thirds of all children experience at least one episode of otitis media before the age of 7 years. The aim of this study was to characterise the attributable effect of several modifiable risk exposures on the risk of >3 episodes of otitis media at age 18 months and 7 years within a large prospective national birth cohort. METHODS: The study used the Danish National Birth Cohort comprising information about otitis media and risk exposures from more than 50,000 mother-child pairs from the period 1996-2002. Logistic regression models were used to estimate odds ratios for the risk factors and to calculate the population attributable fraction. RESULTS: Short time with breastfeeding, early introduction to daycare, cesarean section, and low compliance to the national vaccination program were all associated with an increased risk of >3 episodes of otitis media at 18 months of age and at 7 years of age. The fraction of children with otitis media attributed from breastfeeding lasting for less than 6 months was 10%. Introduction to daycare before the age of 12 months attributed with 20% of the cases of >3 episodes of otitis media. CONCLUSIONS: Short duration of breastfeeding, early introduction into daycare, cesarean section, and low compliance with the national vaccination program increased the risk of experiencing >3 episodes of otitis media at 18 months, and at 7 years of age. These are factors that all can be modulated. PMID- 29447879 TI - Parental preferences for the first consultation for microtia. AB - OBJECTIVES: The aim of our study was to investigate subjective information concerning parental experiences and preferences with regard to the initial information that is provided right after the birth of a child with microtia. The analysis of these data is intended to help professionals improve the way in which such conversations are conducted. As a result, future parents may feel better informed and, hence, better fit to cope with challenges they may encounter having a child with microtia. METHODS: A self-administered questionnaire was sent to 106 parents and caretakers of children with microtia who visited the annual International Microtia and Atresia Conference in the Netherlands, May 2016. RESULTS: Eighty-seven questionnaires were returned (response rate 82%). Results revealed that 26% of the participants did not receive any information about the condition in the perinatal period. Participants who did receive information right after birth were informed by pediatricians and otolaryngolosits in most of the cases. Plastic surgeons and maxillofacial surgeons were the less commonly serving specialties in this role. A majority of the participants experienced their informing consultation as either being "terrible", or "bad". Parents desired more information about all domains regarding microtia. Development, clothing and appearance, and psychology were believed to be the least important domains. CONCLUSIONS: Parents are dissatisfied with several aspects of the initial information that is provided right after the birth of a child with microtia. We believe that there is a need for correct information and patient- and family centered care administered by multiple disciplines. PMID- 29447880 TI - Analysis of risk factors associated with unilateral hearing loss in children who initially passed newborn hearing screening. AB - OBJECTIVE: To analyze 2007 Joint Committee on Infant Hearing (JCIH) risk factors in children with confirmed unilateral hearing loss (UHL) who initially passed newborn hearing screening. METHODS: Retrospective record review of 16,108 infants who passed newborn hearing screening but had one or more JCIH risk factors prompting subsequent follow-up through the universal newborn hearing screening (UNHS) program in Virginia from 2010 to 2012. The study was reviewed and qualified as exempt by the Virginia Commonwealth University Institutional Review Board (IRB) and the Virginia Department of Health. RESULTS: Over the 2-year study period, 14896 (4.9% of total births) children passed UNHS but had the presence of one or more JCIH risk factor. Ultimately, we identified 121 babies from this group with confirmed hearing loss (0.7%), with 48 babies (0.2%) showing UHL. The most common risk factors associated with the development of confirmed UHL after passing the initial screen were neonatal indicators, craniofacial anomalies, family history, and stigmata of syndrome associated with hearing loss. CONCLUSION: Neonatal indicators and craniofacial anomalies were the categories most often found in children with confirmed unilateral hearing loss who initially passed their newborn hearing screen. While neonatal indicators were also the most common associated risk factor in all hearing loss, craniofacial abnormalities are relatively more common in children with UHL who initially passed newborn hearing screening. Further studies assessing the etiology underlying the hearing loss and risk factor associations are warranted. PMID- 29447881 TI - Tympanostomy tubes for serous otitis media and risk of recurrences. AB - OBJECTIVES: To determine the value of tympanostomy tubes (TTs) in the management of serous otitis media (SOM) and the risk factors for SOM recurrence. METHOD: This single-centre cohort study was performed in the University hospital of Amiens, France; and concerned 215 under-12 children having undergone at least one bilateral TT (Shepard grommet-type) placements for SOM. RESULTS: The mean TT retention time was 10 months. SOM recurred in 79 children (62.79%) and thus required a second TT placement (bilaterally in 90% of these cases). Overall, 29.3% of the patients underwent a total of two TT placements, 5.58% underwent three placements and 0.93% underwent four placements. After their first-ever TT placement, 17 children had complications: 10 cases of otorrhoea (4.6%), 4 cases of retraction pocket (1.9%) and 3 perforations of the tympanic membrane (1.4%). At last follow-up, the most common complications were tympanosclerosis (6.9%) and perforation of the tympanic membrane (6.5%). In a multivariate analysis, the only significant risk factors for SOM recurrence were age below 48 months at the time of TT placement, and a TT retention time below 9 months. In contrast, a history of allergy, gastro-oesophageal reflux, prematurity or passive smoking were not significantly associated with recurrence. CONCLUSION: Age at the time of TT placement and the TT retention time were significantly associated with SOM recurrence. The TT retention time and the number of TT placements were not associated with the risk of long-term complications. PMID- 29447882 TI - Acute external otitis as debut of acute myeloid leukemia - A case and review of the literature. AB - Acute leukemia is a well known childhood cancer. The relation between leukemia and otological symptoms has long been established but is highly rare as a debut symptom of leukemia. External otitis is a common condition affecting many children, and most cases are successively treated with topical medicine. Here we present a child with acute external otitis later shown to be the debut symptom of acute myeloid leukemia, to our knowledge the first specific case described. We have reviewed the literature to find red flags for suspicion of severe disease in case of acute external otitis. PMID- 29447883 TI - Whole exome sequencing identifies a pathogenic mutation in WFS1 in two large Chinese families with autosomal dominant all-frequency hearing loss and prenatal counseling. AB - OBJECTIVES: To identify the pathogenic mutation and provide prenatal counseling and diagnosis in two large Chinese families with autosomal dominant all-frequency hearing loss. METHODS: Whole exome sequencing technology was used to identify the pathogenic mutation of the two families. In addition, 298 patients with sporadic hearing loss and 400 normal controls were studied to verify the mutation/polymorphism nature of the identified variant. Prenatal diagnosis was carried out. RESULTS: A rare missense mutation c.2389G > A (p.D572N) in the Wolframin syndrome 1 (WFS1) gene was identified. It was reported in only one previous Chinese study, and never in other populations/ethnicities. The mutation was also found in one patient with sporadic hearing loss (1/298, 0.3%). A healthy baby was born after prenatal diagnosis. CONCLUSION: Our findings strongly suggest that the c.2389G > A mutation in WFS1 is associated with all-frequency hearing loss, rather than low- or high-frequency loss. So far, the mutation is only reported in Chinese. Prenatal diagnosis and prenatal counseling is available for these two Chinese families. PMID- 29447884 TI - Knowledge and attitudes of early childhood development practitioners towards hearing health in poor communities. AB - OBJECTIVE: Within the educational sector of low-and middle-income countries (LMICs), formal and informal early childhood development (ECD) centers are often the first point of contact for majority of children. Since early hearing detection services are mostly absent in LMICs, these ECD centers may serve as the first point of access to screenings for these children. ECD practitioner awareness regarding hearing and hearing loss is essential for the successful implementation of hearing screening programs. This study thus investigated the current knowledge and attitudes of ECD practitioners towards childhood hearing loss in a community representative of typical LMIC contexts. METHOD: Purposive sampling was used to identify ECD centers and participants across a community. Thereafter, a cross-sectional quantitative survey (23 items) was adminstered amongst 82 ECD practitioners. RESULTS: More than 80% of ECD practitioners correctly identified genetics and ear infections as etiological factors of hearing loss. Gaps in knowledge regarding identification techniques for children 3-6 years of age and the impact of hearing loss in the classroom were evident. ECD personnel's duration of experience had a significant effect on overall knowledge and attitude (p < .05; F (1,53) = 8.68). ECD personnel displayed a positive attitude towards children receiving a hearing test (88.3%) and almost all participants indicated the need for more information regarding hearing loss (93.5%). CONCLUSIONS: This study demonstrated a general readiness amongst ECD practitioners for the implementation of ECD hearing screening programs in LMICs, however additional information and guidelines are needed to improve practitioner knowledge and attitudes. PMID- 29447885 TI - Pediatric head and neck squamous cell carcinoma: Patient demographics, treatment trends and outcomes. AB - OBJECTIVES: To examine patient demographics, temporal and treatment trends, and survival outcomes of pediatric non-nasopharyngeal head and neck squamous cell carcinomas using the National Cancer Database. METHODS: The National Cancer Database was queried for pediatric patients (age 0-19 years) diagnosed with squamous cell carcinoma of the head and neck (including oral cavity, oropharynx, nasal cavity, larynx, hypopharynx, and salivary glands) from 2004 to 2013. RESULTS: Of 159 patients identified, the majority had oral cavity SCC (55%). There was no discernable change in incidence trends over the study period with the number of cases per year ranging from 10 to 20 (R2 = 0.174). The predominant treatment regimen for the nasal cavity was trimodality (surgery, radiation, and chemotherapy) treatment (29%), chemotherapy and radiation for the oropharynx (40%), and surgery alone for salivary gland (47%), oral cavity (44%), and larynx (22%). The 5-year overall survival for the entire cohort was 74% and by subsite: oral cavity (66%), oropharynx (68%), nasal cavity (75%), and larynx (95%). Laryngeal disease had statistically significant longer survival when compared to oral cavity (p = .031) or oropharynx (p = .029). CONCLUSION: Although pediatric non-nasopharyngeal head and neck squamous cell carcinomas are rare, practitioners should be aware of this entity and consider it in the differential diagnosis of pediatric malignancies. PMID- 29447886 TI - Recurrences of surgery for antrochoanal polyps in children: A systematic review. AB - OBJECTIVES: The main purpose was to evaluate the recurrence rate after surgery for antrochoanal polyps (ACPs) in children; secondly, we have analyzed the rate of recurrence for different types of surgery and the risk factors involved. METHODS: We performed a systematic review searching PubMed and MEDLINE databases including English-language published studies from June 1989 to October 2017 regarding surgical treatment of ACPs in children. RESULTS: We included thirteen studies, eight were retrospective and five prospective, with 285 participants, the mean rate of recurrence after ACPs surgery was 15.0% (95% CI:11.0-20.0). Functional endoscopic sinus surgery (FESS) was the main type of surgery used for primary cases (75.4%) followed by the combined approach i.e. FESS with a transcanine sinusoscopy or mini Caldwell-Luc (14%), the Caldwell-Luc (CWL) (8%) and simple polypectomy (SP) (2.8%). Our analysis has demonstrated a significant reduction of recurrences using the combined approach 0% (95% CI: 0.0-8.0) compared with FESS 17.7% (95% CI: 12.8-23.4) or SP 50% (95% CI:15.7-84.3) (p < .05) but no significant differences with CWL 9.1% (95% CI: 1.1-29.2) and others surgical approaches (p > .05). The analysis of the possible risk factors involved in recurrences are inconclusive. CONCLUSION: Recurrences of ACPs in children are still high. The endoscopic sinus surgery is considered the first choice for primary treatment, whilst the external approach may be a valid option in case of recurrence. It seems that the combined approach could reduce recurrence rates in selected patients that cannot be completely managed with endoscopy. PMID- 29447887 TI - Thirty-day perioperative outcomes in resection of cervical lymphatic malformations. AB - INTRODUCTION: Limited information exists regarding short-term morbidity in the resection of lymphatic malformations. In order to make informed collaborative medical decisions, clinicians and families would benefit from information on 30 day outcomes and the expected course associated with surgical excision of lymphatic malformations. METHODS: A retrospective chart review was conducted to develop a case series of patients who underwent resection of lymphatic malformation at a pediatric tertiary care center between June 1, 2007 and September 30, 2016. Demographic data, disease characteristics, operative details, post-operative care, and adverse events in the 30-day post-operative period were analyzed. Primary outcomes included facial nerve dysfunction, seroma formation, re-admission, and overall rate of any complications. Secondary outcomes included operative time, duration of stay, and duration of drain placement. RESULTS: Forty nine excisions were performed in 46 patients (21 male, 25 female). Median age was 5 years. All but 7 cases were performed as the initial primary intervention. Median operative time was 96 min (range 22-224). Higher stage lesions (3-5) were associated with a longer operative time (p = .03). Median length of stay was 2 days (range 0-35). Higher stage lesions were associated with an increased length of stay (p = .0004). Median duration of drain placement was 2 days (range 0-14), and was longer in higher stage lesions (p = .0002). Higher stage lesions (p = .002) and cases ultimately found to have residual disease (p = .019) were associated with an increased overall rate of complications; there was no association between cyst type and rate of complications. Seroma formation (31%) and transient facial nerve weakness (26%) were the two most common complications observed. There was no association between stage or cyst type and likelihood of seroma formation. Seromas resolved after a median duration of 3 months and transient facial nerve weakness resolved after a median duration of 2 months. 3 patients required return to the OR and 1 patient was readmitted. CONCLUSION: The overall rate of adverse events after surgical excision of cervical lymphatic malformations is relatively low. Increased rates of complications can be expected with higher stage. Similarly, for these higher stage lesions, a longer operative time, hospital stay, and duration of drain placement can be expected. PMID- 29447888 TI - Pathogenesis of chronic rhinosinusitis in patients affected by beta-thalassemia major and sickle cell anaemia post allogenic bone marrow transplant. AB - OBJECTIVES: Sickle cell anemia (SCA) and beta -thalassemia major are well recognized beta-globin gene disorders of red blood cells associated to mortality and morbidity included bone morbidities due to ineffective erythropoiesis and bone marrow expansion, which affect every part of the skeleton. While there are an abundance of described disease manifestations of the head and neck, the manner of paranasal sinuses involvement and its relations to beta-thalassemia and SCA process was not studied yet. Therefore, the aim of this study was to investigate a possible increased risk of rhinosinusitis and the real pathogenetic mechanism of it, comparing these two hematological diseases using msCT, gold standard for paranasal sinuses evaluation. METHODS: A retrospective analysis of 90 patients affected by beta-thalassemia major or SCA (respectively 59 and 31) underwent allogeneic bone marrow transplantation (BMT), and 44 control subjects was performed. Both patient categories and control group have been subjected to hematological and radiological evaluation using 64-multidetector-row CT scanner without contrast injection. RESULTS: Statistical analysis reveals that patients of the two study groups exhibit a significantly increased risk of sinusitis in comparison with the normal controls (RR: 3.55 for beta-thalassemic pediatric subjects; RR: 3.35 for SCA pediatric subjects). A significant difference (p < 0,5) was found between the beta -thalassemic patients on the one side, and SCA and control group on the other side, with regard to the evaluation of the typical anatomic alteration of maxillary sinus: beta-thalassemic children had significant increase in the bone thickness of anterior and lateral sinus walls and significant reduction in volume and density compared to SCA patients and control group, with normal conditions of these parameters. CONCLUSIONS: In these hematological patients, there is an increased incidence of sinonasal infections due their therapy-induced immunosuppression post transplantation. In beta thalassemic patients, furthermore, the specific anatomical variants play an important confounding factor in radiological interpretation of CT images. Therefore, a cranio-facial CT scan evaluation could be a useful tool in the management of upper airway infections after BMT and should be a routinely exams in order to avoid useless surgical or antibiotic approaches. PMID- 29447889 TI - Correlations between pediatric obstructive sleep apnea and longitudinal growth. AB - OBJECTIVES: Pediatric obstructive sleep apnea has a relatively high prevalence and has various negative health and behavioral consequences. Among the various complications of pediatric obstructive sleep apnea, growth disturbance is still controversial. METHOD: 745 pediatric subjects with obstructive sleep apnea diagnosed by in-lab polysomnography were enrolled, after excluding ineligible subjects with abnormal growth related factors. Height, weight, and BMI of enrolled patients were measured and statistically converted to z-scores, and the converted data were analyzed statistically with the polysomnographic results. Multiple linear regression were used to analyze the relationships between age, gender, z-score for weight, polysomnography results, and z-score for height. RESULTS: Patients with higher respiratory related index or lower mean/lowest oxygen saturation of PSG showed smaller z-score for height. Mean apnea hypopnea index and standard deviation of enrolled patients was 7.46 +/- 12.92, with moderate severity. And mean z-score for height and standard deviation was 0.21 +/ 1.15. Apnea hypopnea index, respiratory disturbance index, obstructive apnea index, and hypopnea index, respiratory related results of polysomnography, were statistically negative correlated with a z-score for height. And mean oxygen saturation and lowest oxygen saturation, oxygen saturation results of polysomnography, were statistically positive correlated with a z-score for height. CONCLUSIONS: Respiratory related results and oxygen saturation results of polysomnography show negative and positive correlation with z-score for height. Therefore, pediatric obstructive sleep apnea have a negative effect on longitudinal growth. PMID- 29447890 TI - Outcomes of adenoidectomy-alone in patients less than 3-years old. AB - OBJECTIVES: 1. Determine the percentage of patients under the age of 3 undergoing adenoidectomy-alone who require subsequent management of residual sleep disordered breathing (SDB).2. Characterize complications following adenoidectomy and determine if any perioperative factors are associated with intra-operative or post-operative complications and outcomes. METHODS: Case series with chart review was conducted including children seen at a tertiary care children's hospital between 2008 and 2012. Consecutive patients under the age of 3 who underwent adenoidectomy-alone were identified by billing codes. After excluding those with syndromes, partial adenoidectomies, and those without follow-up, 148 patients were included. Predictors of requiring additional surgery for SDB were evaluated using log-rank tests or Cox proportional hazards regression. RESULTS: Median age at time of initial adenoidectomy was 27.5 months (range 11-36 months) and the patient population was comprised of 66.2% males (n = 98/148) and 89.2% Caucasians (n = 132/148). 56.5% (n = 74/131) of patients continued to have residual symptoms of SDB and 34.5% (n = 51/148) underwent additional surgical intervention. Multivariable survival analysis revealed GERD (HR, 6.21; CI, 1.29-29.77, p = .022) and tonsil size (HR, 4.07; CI, 1.57-10.51, p = .004) were significant predictors of additional surgery in this group of patients under the age of 3. There was no observed difference in intra- and post-operative complication rates between patients with and without additional operative intervention. CONCLUSIONS: Residual SDB symptoms following adenoidectomy in patients less than 3 years of age are common and require additional surgery at a high rate. Medical comorbidities such as GERD and large tonsil size may help predict the need for additional surgery. PMID- 29447891 TI - Parents' experiences managing their child's complicated postoperative recovery. AB - OBJECTIVE: Tonsillectomy is commonly performed as same-day surgery and parents are heavily relied upon for management of children's postoperative recovery. The objective of this study was to provide an in-depth description of the experiences parents face when managing their child's complicated postoperative recoveries at home. METHODS: An exploratory qualitative study at an academic pediatric hospital in Eastern Canada was performed. Participants included 12 parents of children aged 3-6 years who underwent adeno/tonsillectomy and experienced unexpected outcomes or complications during the postoperative recovery period. Parents participated in semi-structured interviews within 6 months of their child's surgery. Interviews were transcribed verbatim and thematic analysis was used to identify themes in the parents' experiences. RESULTS: Parents described struggling to make the decision to come back to hospital, that adequate information does not prevent emotional difficulties, and feeling somewhat responsible for the unexpected outcome or complicated course of recovery. Communication with healthcare providers was considered very important in helping with the recovery process. CONCLUSION: This research helps to inform healthcare professionals about how they might better support families during complicated recovery processes. Areas of action may include clear communication, setting expectations, and psychosocial support. PMID- 29447892 TI - Differences in postoperative maladaptive behavioral changes between partial and total tonsillectomy patients. AB - INTRODUCTION: Behavioral difficulties associated with sleep-disordered breathing (SDB) improve after tonsillectomy, but surgery may lead to the development of short-term postoperative maladaptive behavioral changes (PMBCs). These PMBCs have not been compared between total and partial tonsillectomy patients. METHODS: SDB patients aged 1-6 years undergoing tonsillectomy were recruited. Parent phone surveys were conducted at 48-72 hours and 1-2 weeks postoperatively. Parents identified PMBCs using the Post-Hospital Behavior Questionnaire (PHBQ), scoring changes in behavior compared to baseline. PMBCs were defined by PHBQ scores >0 and compared by one-tailed t-test. Postoperative pain was categorized as mild, moderate, and severe pain using the Parents' Postoperative Pain Measure (PPPM). Differences in pain levels were analyzed by Chi-squared test. A p-value <0.05 was deemed statistically significant. RESULTS: Seventy-eight children completed the study, with 29 total tonsillectomy and 49 partial tonsillectomy patients. At both time points after surgery, PHBQ scores were higher in total tonsillectomy patients than in partial tonsillectomy patients (3.41 +/- 3.53 versus 1.94 +/- 2.25 at 2-3 days, p = .013). PMBCs were also more frequent in total than partial tonsillectomy patients (76% versus 59% at 2-3 days; 28% versus 7% at 1-2 weeks). Meanwhile, distribution of pain levels was similar between both partial and total tonsillectomy patients. CONCLUSIONS: Our study indicates that total tonsillectomy patients more frequently experience PMBCs than do partial tonsillectomy patients despite similar distributions in pain levels postoperatively. This difference in PHBQ scores between total and partial tonsillectomy patients should be further explored. PMID- 29447893 TI - iPhone otoscopes: Currently available, but reliable for tele-otoscopy in the hands of parents? AB - OBJECTIVES: Tele-otoscopy has been validated for tympanostomy surveillance and remote diagnosis when images are recorded by trained professionals. The CellScope iPhone Otoscope is a device that may be used for tele-otoscopy and it enables parents to record their children's ear examinations and send the films for remote physician diagnosis. This study aims to determine the ability to diagnose, and the reliability of the diagnosis when utilizing video exams obtained by a parent versus video exams obtained by an otolaryngologist. METHODS: Parents of children ages 17 years or younger attempted recordings of the tympanic membrane of their children with the CellScope after a video tutorial; a physician subsequently used the device to record the same ear. Recordings occurred prior to standard pediatric otolaryngology office evaluation. Later, a remote pediatric otolaryngologist attempted diagnosis solely based on the videos, blinded to whether the examination was filmed by a parent or physician. Interrater reliability between video diagnosis and original diagnosis on pneumatic otoscopy was measured, and objective tympanic membrane landmarks visualized on the films were recorded. RESULTS: Eighty ears were enrolled and recorded. There was low interrater agreement (k = 0.42) between diagnosis based on parent videos as compared with pneumatic otoscopy. There was high agreement (k = 0.71) between diagnosis based on physician videos and pneumatic otoscopy. Physician videos and parent videos had only slight agreement on objective landmarks identified (k = 0.087). CONCLUSIONS: iPhone otoscopy provides reliable tele-otoscopy images in when used by trained professionals but, currently, images obtained by parents are not suitable for use in diagnosis. PMID- 29447894 TI - Cochlear implantation in pediatric patients with Cockayne Syndrome. AB - Cockayne Syndrome (CS) is a rare, autosomal recessive disorder characterized by a spectrum of phenotypic abnormalities, including progressive sensorineural hearing loss (SNHL) that involves both peripheral and central components. To date, a single series of CS patients undergoing cochlear implant (CI) placement has been reported; this study reports on additional previously unreported pediatric CI recipients. Subjective benefits were noted early after activation in both patients, and speech perception scores improved over time as well, varying from 42 to 70% (versus 0-12% previously). Thus, we report that cochlear implantation in pediatric patients with CS can be effective in the management of progressive SNHL.

AB - Sternal clefts are rare malformations, especially in their complete form, which results from a lack of fusion of the sternal bars, which is normally done at the 9th week of intra uterine life. The incomplete form is often associated with other malformations of the chest wall, or falling within the framework of a polymalformative syndrome, the diagnosis is easy, being done with the inspection and the palpation, the paraclinical examinations are useful for confirming the diagnosis. We report the case of a total congenital sternal cleft isolated in an asymptomatic 20-day-old newborn. Thoracic CT, with threedimensional reconstructions, without injection of the contrast product confirmed the diagnosis, showing the presence of two hemistonids hypoplastic. The aim of our work is to draw attention to this pathology from birth because surgery must be undertaken during the first weeks of life to protect the heart and large vessels from any trauma, to improve respiratory dynamics and for aesthetic reasons. PMID- 29447896 TI - Bony cochlear nerve canal stenosis in pediatric unilateral sensorineural hearing loss. AB - OBJECTIVES: This study was performed to evaluate the frequency of bony cochlear nerve canal (BCNC) stenosis and its clinical significance in pediatric patients with unilateral sensorineural hearing loss (SNHL) of unknown etiology. MATERIALS AND METHODS: We analyzed the medical records and temporal bone computed tomography (CT) results of patients less than 13 years of age with a diagnosis of unilateral SNHL of unknown etiology between July 2007 and July 2017. We compared the BCNC diameter between both sides and analyzed the age at diagnosis, degree of hearing loss, and accompanying inner ear anomalies. RESULTS: In 42 patients, the mean age at diagnosis was 7.4 +/- 3.6 years, and the average hearing level in the affected ear was 87.9 +/- 20.0 dB HL (decibels hearing level). The average diameter of the BCNC was 1.22 +/- 0.75 mm on the affected side and 1.96 +/- 0.52 mm on the normal side. The most suitable criterion for BCNC stenosis appeared to be a diameter of 1.2 mm by the recursive partitioning procedure. With application of this criterion, the rate of BCNC stenosis was significantly greater on the affected side than on the normal side (52.4% vs. 4.8%, respectively; P < 0.05). A narrow internal acoustic canal was found in two patients, and vestibular and cochlear anomalies were found in three patients each. CONCLUSIONS: Our results suggest that it is reasonable to set a diameter of 1.2 mm as a cutoff for BCNC stenosis, and also that BCNC stenosis is a common cause of unilateral SNHL of unknown etiology in childhood.

It is often neglected in children with late presentation. This study aimed at determining the prevalence, sociodemographic features, comorbid illnesses, complications and quality of life in children with allergic rhinitis in the study institution. MATERIALS AND METHODS: This is a prospective hospital based study of children with allergic rhinitis in Ekiti state university teaching hospital, Ado Ekiti. The study was carried out in ENT department over a period of two years (between June 2015 to May 2017). Informed consent was obtained from the parents/guardian/patients and consented patients were enrolled into the study. Data were obtained by pretested interviewers assisted questionnaire. Details of their history, physical examination and investigations were carried out and findings were documented. All data obtained were descriptively analysed using SPSS version 18.0 and presented in simple tables and charts. Ethical clearance was sought for and obtained from the ethical committee of the hospital. RESULTS: A total of 4341 patients were seen out of which 265 were children with allergic rhinitis. Prevalence of allergic rhinitis in children in this study was 6.1%. There were 63.0% males with male to female ratio of 2:1. Allergic rhinitis was peaked at preschool age group (1-5 years) accounted for 47.9%. A total of 42.3% participants were living in urban setting while 57.7% were from rural setting. Majorities (40.4%) of the patients were in nursery and parent's major occupation was mainly farming in 27.2%. There was positive family history of allergy in 54.7% patients. Perennial allergic rhinitis were noted in 63.8% patients while seasonal allergic rhinitis were noted in 36.2% patients. Major form of allergens was inhalant 81.8% and the least form of allergen was ingestant 5.7%. The commonest identified trigger factors among the study population were as follows: dust, cold weather and smoke which were accounted for 59.6%, 37.4% and 18.9% of the study patients respectively. Other noted triggering factors were soap and perfume which accounted for 4.2% and 1.1% respectively. Major associated comorbid illnesses among the patients were tonsils hypertrophy, adenoid hypertrophy and inferior turbinate hypertrophy which accounted for 55.5%, 46.4% and 40.4% respectively. Clinical presentations of allergic rhinitis in this study were mainly 75.8% nasal blockage, 65.3% runny nose and 8.5% recurrent sneezing. Commonest complications of allergic rhinitis were 35.1% pharyngitis, 32.1% otitis media and 28.3% headache. Treatment of allergic rhinitis leads to improvement on the clinical features in 90.1% patients. No significant improvement in clinical features were noticed in 9.8% patients. None of the studied patients reported worse clinical condition after treatment of allergic rhinitis. No mortality was recorded from allergic rhinitis in this study. CONCLUSION: Allergic rhinitis affect all paediatric age group and there were delayed presentation in the participants. There were associated comorbid illnesses, complications and affectation of quality of life at presentation in majority of the patients. PMID- 29447898 TI - Challenges and outcomes of cholesteatoma management in children with Down syndrome. AB - INTRODUCTION: The high incidence of chronic otitis media with effusion and Eustachian tube dysfunction in children with Down syndrome (DS) may predispose them to cholesteatoma formation. Establishing the diagnosis, choosing the appropriate operative intervention, and post-operative care can be challenging. OBJECTIVE: To describe management strategies for cholesteatoma diagnosis, surgical treatment, and post-operative management in children with Down syndrome. METHODS: Retrospective case series of 14 patients (17 total ears) with Down syndrome diagnosed with cholesteatoma over a 9-year period. RESULTS: A total of 14 patients with cholesteatoma (3 with bilateral disease) were analyzed. Thirteen ears (76.5%) had >=2 tympanostomy tubes insertions prior to cholesteatoma diagnosis, and otorrhea and hearing loss were the most common presenting symptoms. Common pre-operative CT scan findings included mastoid sclerosis and ossicular erosion. The average age at first surgery was 9.8 years, and the average follow-up was 4.3 years. For acquired cholesteatoma, most ears were managed with canal wall up (CWU) approaches, but ultimately 6/15 (40.0%) required canal wall down (CWD) approaches. Postoperatively, 3 (20.0%) ears developed new tympanic membrane retraction pockets, but no recurrent cholesteatoma. Four (26.7%) ears developed recurrent disease, and 3 (20.0%) had residual disease at secondary procedures. Ossiculoplasty was performed in 4 ears. Twelve (70.6%) ears were rehabilitated with hearing aids or FM systems. CONCLUSIONS: The diagnosis of cholesteatoma in Down syndrome was associated with otorrhea, hearing loss, and CT scan findings of ossicular erosion and mastoid sclerosis. Most cases were managed with CWU surgical approaches. Hearing aid use was common post-operatively. PMID- 29447899 TI - Geographic health disparities in the Los Angeles pediatric esophageal foreign body population. AB - OBJECTIVE: To assess geographical sociodemographic differences in the pediatric esophageal foreign body population of Los Angeles. METHODS: We retrospectively reviewed the medical records of 128 consecutive pediatric patients at Children's Hospital Los Angeles (CHLA) from 2014 to 2017 with a diagnosis of a retained foreign body in the esophagus removed by rigid or flexible esophagoscopy. Sociodemographic information including zip code of residence was extracted and analyzed with Chi-square, Fisher's exact test, and multivariable logistic regression. RESULTS: The average age of patients with a retained esophageal foreign body in this study was 2.5 years old, 52.3% were male, 91.4% had no past medical history, 53.1% were Hispanic, 82.0% had public health insurance, and 63.3% were transfers from an outside hospital. The most common foreign body removed was a coin. There were no significant differences in gender, race, type of health insurance, or income between patients that lived within 10 miles of CHLA versus farther than 10 miles. On multivariable analysis, zip codes with a high volume of esophageal foreign bodies were more likely to be lower income neighborhoods. Gender, race, type of health insurance, and distance from CHLA were not risk factors for zip codes with a high volume of esophageal foreign bodies. CONCLUSION: Geographic areas in the greater Los Angeles community with a high volume of retained esophageal foreign bodies requiring endoscopic removal at our institution are associated with lower income neighborhoods. Further studies should be performed to better understand health disparities within the U.S. pediatric esophageal foreign body population. PMID- 29447900 TI - Microbiology and antibiotic therapy of subperiosteal orbital abscess in children with acute ethmoiditis. AB - OBJECTIVE: The objective of this study was to investigate the microbiological cultures and the management of acute ethmoiditis complicated by subperiosteal orbital abscess (SPOA) in a pediatric population. METHODS: The medical records of children under 18 years old was performed in a tertiary referral pediatric center from January 2009 to April 2017. Clinical examination, computed tomography scans, medical and surgical treatments were reviewed and compared to other studies in literature. RESULTS: One hundred and twenty-nine children were hospitalized for acute ethmoiditis. Among them, forty eight were complicated by SPOA. The mean age of these children were 7 years (range 10 months-16 years). Thirtyfour underwent surgical drainage; for the others the medical treatment was sufficient. Microbiological samples were obtained during the surgical intervention and were contributive in 91% of cases. Streptococcus spp was the most frequently encountered bacteria (60% of cases). We also found anaerobic bacteria (12%), and Staphylococcus aureus (12%). 94% of children received two intravenous antibiotics (a third-generation cephalosporin and metronidazole) for a mean duration of four days. Then the oral treatment was based on amoxicillin-clavulanate during about 8.5 days. All children were cured without sequelae. CONCLUSIONS: For five years Streptococcus milleri, Staphylococcus spp and anaerobic bacteria are on the rise in acute ethmoiditis complicated by SPOA. That is why antibiotics must be adapted to these bacteria even in children under ten years old. PMID- 29447901 TI - Hospital cost analysis of children with preseptal cellulitis. AB - OBJECTIVE: Hospitalization of the children with preseptal cellulitis creates a burden on healthcare costs. This study aimed to analyze the hospital costs for preseptal cellulitis and determine the factors contributing. METHODS: Children, between 1 and 18 years old, who were admitted to hospital for preseptal cellulitis from May 2013 to December 2016 were included in the study. Patients were divided into groups by age (under or equal to five years and older than five years) and by the presence of sinusitis. Demographics, length of stay and total and categorical hospital costs were evaluated retrospectively. RESULTS: The study included 54 patients with a mean age of 5 years. Thirty one of the patients were under five years of age. The most common symptoms were swelling (94.4%) and redness (83.3%) around eye. Among the predisposing factors, sinusitis was the most common one (37%). The average length of stay was 4.5 days. Total hospital cost of all patients was $11,841. Antibiotic costs (37%) and inpatient floor costs (36%) were the greatest expenditures. Between age groups, length of stay was longer, and inpatient floor and antibiotic costs were significantly higher in the group of >5 years (p = 0.007, p = 0.004 and p = 0.001, respectively). In the group with sinusitis, length of stay was longer, and all hospital costs were significantly higher compared to the group without sinusitis (p < 0.001). There was a strong, positive correlation between length of stay and hospital costs (r = 0.854, n = 53, p < 0.001). Sinusitis was a significant factor (p < 0.001) for longer length of stay, but age was not (p = 0.841). CONCLUSION: Sinusitis was found to be an important factor contributing to longer length of stay and higher hospital costs for preseptal cellulitis. Oral or ambulatory intravenous antimicrobial treatment strategies might decrease the hospital expenditure in these patients; however care should be taken in the presence of sinusitis. PMID- 29447902 TI - The erythrocyte osmotic resistance test as screening tool for cholesterol-related lysosomal storage diseases. AB - BACKGROUND: Erythrocyte volume regulation and membrane elasticity are essential for adaptation to osmotic and mechanical stress, and life span. Here, we evaluated whether defective cholesterol trafficking caused by the rare lysosomal storages diseases (LSDs), Niemann-Pick type C (NPC) and Lysosomal acid lipase (LAL) deficiency (LALD) impairs these properties. Moreover, we tested whether measurements of cholesterol membrane content and osmotic resistance serve as a screening test for these LSDs. METHODS: Patients were genotyped for mutations in NPC1, NPC2, or LIPA genes. We measured LSD plasma biomarkers and LAL activity. Red blood cells (RBC) membrane cholesterol content was evaluated in 73 subjects. Osmotic resistance tests (ORT) were conducted in 121 blood samples from LSD suspected patients and controls. RESULTS: We did not find statistically significant differences between RBC cholesterol content between subjects and controls. However, the ORT, particularly at 0.49% (w/v) hypotonic sodium chloride solution, revealed a significant higher osmotic resistance in LSDs patients than in controls. We established a cut-off value of <=51% of haemolysis with sensibility and specificity values of 80% and 70%, respectively. CONCLUSIONS: NPC and LALD do not alter cholesterol content in the RBC membrane but increase osmotic resistance. Therefore, ORT serves as screening test for the studied LSDs. PMID- 29447903 TI - Mass spectrometric identification of bromotryptophan containing conotoxin sequences from the venom of C. amadis. AB - Four 30 residue conotoxin have been identified from the venom of C. amadis. MS/MS analysis of crude venom subjected to global reduction/alkylation yielded fragmentation patterns, which permitted searching and matching with a database of putative mature toxin sequences obtained from transcriptomic analysis. Of the four sequences identified, Am3408(Am6.1b), Am3452(Am6.1c), Am3136(Am6.2a) and Am3214(Am6.2b), three contain bromotryptophan residues, while an additional post translational modification, gamma carboxylation of glutamic acid, is present in Am3408(Am6.1b)/3452(Am6.1c). The conotoxins belong to the O1/O2 gene superfamily and possess cysteine framework VI/VII. While, the cysteine patterns show a similarity to omega conotoxins, the three C. amadis peptides are highly negatively charged and possess a significant content of hydrophobic residues.

AB - Scorpion venoms comprise cocktails of proteins, peptides, and other molecules used for immobilizing prey and deterring predators. The composition and efficacy of scorpion venoms appears to be taxon-specific due to a coevolutionary arms race with prey and predators that adapt at the molecular level. The taxon-specific components of scorpion venoms can be used as barcodes for species identification if the amount of intraspecific variation is low and the analytical method is fast, inexpensive and reliable. The present study assessed the extent of intraspecific variation in newly regenerated venom collected in the field from geographically separated populations of four southern African scorpion species: three buthids, Parabuthus granulatus (Ehrenberg, 1831), Uroplectes otjimbinguensis (Karsch, 1879), and Uroplectes planimanus (Karsch, 1879), and one scorpionid, Opistophthalmus carinatus (Peters, 1861). Although ion signal patterns were generally similar among venom samples of conspecific individuals from different populations, MALDI-TOF mass spectra in the mass range m/z 700 10,000 revealed only a few ion signals that were identical suggesting that species identification based on simple venom mass fingerprints (MFPs) will be more reliable if databases contain data from multiple populations. In general, hierarchical cluster analysis (HCA) of the ion signals in mass spectra was more reliable for species identification than counts of mass-identical substances in MFPs. The statistical approach revealed conclusive information about intraspecific diversity. In combination with a comprehensive database of MALDI TOF mass spectra in reflectron mode, HCA may offer a method for rapid species identification based on venom MFPs.

PMID- 29447906 TI - Cell death in neural precursor cells and neurons before neurite formation prevents the emergence of abnormal neural structures in the Drosophila optic lobe. AB - Programmed cell death is a conserved strategy for neural development both in vertebrates and invertebrates and is recognized at various developmental stages in the brain from neurogenesis to adulthood. To understand the development of the central nervous system, it is essential to reveal not only molecular mechanisms but also the role of neural cell death (Pinto-Teixeira et al., 2016). To understand the role of cell death in neural development, we investigated the effect of inhibition of cell death on optic lobe development. Our data demonstrate that, in the optic lobe of Drosophila, cell death occurs in neural precursor cells and neurons before neurite formation and functions to prevent various developmental abnormalities. When neuronal cell death was inhibited by an effector caspase inhibitor, p35, multiple abnormal neuropil structures arose during optic lobe development-e.g., enlarged or fused neuropils, misrouted neurons and abnormal neurite lumps. Inhibition of cell death also induced morphogenetic defects in the lamina and medulla development-e.g., failures in the separation of the lamina and medulla cortices and the medulla rotation. These defects were reproduced in the mutant of an initiator caspase, dronc. If cell death was a mechanism for removing the abnormal neuropil structures, we would also expect to observe them in mutants defective for corpse clearance. However, they were not observed in these mutants. When dead cell-membranes were visualized with Apoliner, they were observed only in cortices and not in neuropils. These results suggest that the cell death occurs before mature neurite formation. Moreover, we found that inhibition of cell death induced ectopic neuroepithelial cells, neuroblasts and ganglion mother cells in late pupal stages, at sites where the outer and inner proliferation centers were located at earlier developmental stages. Caspase-3 activation was observed in the neuroepithelial cells and neuroblasts in the proliferation centers. These results indicate that cell death is required for elimination of the precursor cells composing the proliferation centers. This study substantiates an essential role of early neural cell death for ensuring normal development of the central nervous system. PMID- 29447907 TI - Wilhelm His' lasting insights into hindbrain and cranial ganglia development and evolution. AB - Wilhelm His (1831-1904) provided lasting insights into the development of the central and peripheral nervous system using innovative technologies such as the microtome, which he invented. 150 years after his resurrection of the classical germ layer theory of Wolff, von Baer and Remak, his description of the developmental origin of cranial and spinal ganglia from a distinct cell population, now known as the neural crest, has stood the test of time and more recently sparked tremendous advances regarding the molecular development of these important cells. In addition to his 1868 treatise on 'Zwischenstrang' (now neural crest), his work on the development of the human hindbrain published in 1890 provided novel ideas that more than 100 years later form the basis for penetrating molecular investigations of the regionalization of the hindbrain neural tube and of the migration and differentiation of its constituent neuron populations. In the first part of this review we briefly summarize the major discoveries of Wilhelm His and his impact on the field of embryology. In the second part we relate His' observations to current knowledge about the molecular underpinnings of hindbrain development and evolution. We conclude with the proposition, present already in rudimentary form in the writings of His, that a primordial spinal cord-like organization has been molecularly supplemented to generate hindbrain 'neomorphs' such as the cerebellum and the auditory and vestibular nuclei and their associated afferents and sensory organs. PMID- 29447908 TI - Primary lymphedema and other lymphatic anomalies are associated with 22q11.2 deletion syndrome. AB - BACKGROUND: Lymphedema is an abnormal accumulation of interstitial fluid within the tissues. Primary lymphedema is caused by aberrant lymphangiogenesis and it has been historically classified based on age at presentation. Although most cases are sporadic, primary lymphedema may be familial or present in association with chromosomal abnormalities and syndromic disorders. To the best of our knowledge, primary lymphedema has never been described in patients with 22q11.2 deletion syndrome. METHODS AND RESULTS: We identified 4 patients with 22q11.2 deletion syndrome and primary lymphedema via our International 22q11.2 Deletion Syndrome Consortium. All patients underwent comprehensive clinical, laboratory and imaging assessments to rule out other causes of lymphedema. All patients had de novo typical deletions and family histories were negative for lymphedema. CONCLUSIONS: We report the novel association of primary lymphedema with 22q11.2 deletion syndrome. Importantly, animal models demonstrated Tbx1 playing a critical role in lymphangiogenesis by reducing Vegfr3 expression in lymphatic endothelial cells. Moreover, the VEGFR3 pathway is essential for lymphangiogenesis with mutations identified in hereditary primary lymphedema. Accordingly, our findings provide a new insight into understanding cellular mechanisms of lymphangiogenesis disorders. PMID- 29447910 TI - Preventing non-contact ACL injuries in female athletes: What can we learn from dancers? AB - OBJECTIVES: To investigate the effects of dance experience and movement instruction on lower extremity kinematics and muscle activation during a landing task. DESIGN: Cross-sectional case control. SETTING: Laboratory setting. PARTICIPANTS: 27 female subjects (age 18-25) in 2 groups: dancers (n = 12) and non-dancers (n = 15). MAIN OUTCOME MEASURES: Lower extremity biomechanics during drop landing were analyzed. Subjects performed drop landings after watching an instructional video without verbal instructions (NI), followed by repeat assessment after watching the same videos with specific verbal instructions (VI). Surface electromyography (EMG) was used to measure the activation of gluteus maximus and medius during the deceleration phase of landings. Peak knee and hip frontal plane angles during landing were acquired using a 3-D motion capture system. RESULTS: Compared to non-dancers, dancers demonstrated generally greater gluteus maximus activation and a decreased knee abduction (i.e. valgus) angle during drop landing. A significant interaction showed that instruction led to increased knee valgus angle in non-dancers but not dancers (p = .014). CONCLUSIONS: Our findings suggest that experienced dancers demonstrate safer landing strategies compared to recreational athletes. Providing acute movement instruction was shown to disrupt the landing mechanics in those with no dance training experience. PMID- 29447909 TI - Phosphatidylserine-stimulated production of N-acyl-phosphatidylethanolamines by Ca2+-dependent N-acyltransferase. AB - N-acyl-phosphatidylethanolamine (NAPE) is known to be a precursor for various bioactive N-acylethanolamines including the endocannabinoid anandamide. NAPE is produced in mammals through the transfer of an acyl chain from certain glycerophospholipids to phosphatidylethanolamine (PE) by Ca2+-dependent or independent N-acyltransferases. The epsilon isoform of mouse cytosolic phospholipase A2 (cPLA2epsilon) was recently identified as a Ca2+-dependent N acyltransferase (Ca-NAT). In the present study, we first showed that two isoforms of human cPLA2epsilon function as Ca-NAT. We next purified both mouse recombinant cPLA2epsilon and its two human orthologues to examine their catalytic properties. The enzyme absolutely required Ca2+ for its activity and the activity was enhanced by phosphatidylserine (PS). PS enhanced the activity 25-fold in the presence of 1 mM CaCl2 and lowered the EC50 value of Ca2+ >8-fold. Using a PS probe, we showed that cPLA2epsilon largely co-localizes with PS in plasma membrane and organelles involved in the endocytic pathway, further supporting the interaction of cPLA2epsilon with PS in living cells. Finally, we found that the Ca2+-ionophore ionomycin increased [14C]NAPE levels >10-fold in [14C]ethanolamine labeled cPLA2epsilon-expressing cells while phospholipase A/acyltransferase-1, acting as a Ca2+-independent N-acyltransferase, was insensitive to ionomycin for full activity. In conclusion, PS potently stimulated the Ca2+-dependent activity and human cPLA2epsilon isoforms also functioned as Ca-NAT. PMID- 29447911 TI - Fluorescent protein tagged hepatitis B virus capsid protein with long glycine serine linker that supports nucleocapsid formation. AB - Fusion core proteins of Hepatitis B virus can be used to study core protein functions or capsid trafficking. A problem in constructing fusion core proteins is functional impairment of the individual domains in these fusion proteins, might due to structural interference. We reported a method to construct fusion proteins of Hepatitis B virus core protein (HBc) in which the functions of fused domains were partially kept. This method follows two principles: (1) fuse heterogeneous proteins at the N terminus of HBc; (2) use long Glycine-serine linkers between the two domains. Using EGFP and RFP as examples, we showed that long flexible G4S linkers can effectively separate the two domains in function. Among these fusion proteins constructed, GFP-G4S186-HBc and RFP-G4S47-HBc showed the best efficiency in rescuing the replication of an HBV replicon deficient in the core protein expression, though both of the two fusion proteins failed to support the formation of the relaxed circular DNA. These fluorescent protein tagged HBcs might help study related to HBc or capsids tracking in cells. PMID- 29447912 TI - Immunogold-agglutination assay for direct detection of HPV-16 E6 and L1 proteins from clinical specimens. AB - HPV-16 infection is the most common cause of cervical cancer. As HPV-16 transforms the cell, E6 oncoprotein is over-expressed. Therefore, molecular detection of HPV-16 E6 mRNA is now being used for diagnosis and prediction of cancer development. Besides detecting E6 mRNA, a rapid lateral flow detecting the E6 protein using enzyme immunoassay is also now on market with a sensitivity of 53.5% for cervical intraepithelial neoplasia (CIN)-3 or more severe (CIN-3+). Here, an immunogold-agglutination assay was developed to detect not only HPV-16 E6 protein but also L1, a major capsid protein found in the productive stage of the virus. Evaluation of this test using HPV-16 DNA positive cervical samples showed that the HPV-16 E6 immunogold-agglutination assay results correlated well with the progression of the cervical lesions, i.e., 10.34% of CIN-1, 68.75% of CIN-3 and 80% of cancer (CaCx) and none for healthy normal samples. Interestingly, the HPV-16 L1 protein was found in most of the cases with cancer indicating the possibility of virion production. Immunogold-agglutination assay for E6 protein is simpler, easier to be performed with a sensitivity of 73.1% for CIN-3+ suggesting a good method for laboratory diagnostic use. PMID- 29447913 TI - Microbiological surveillance of plasmid mediated colistin resistance in human Enterobacteriaceae isolates in Romagna (Northern Italy): August 2016-July 2017. AB - OBJECTIVES: To start a surveillance program to investigate the possible diffusion of mobilized colistin resistance genes in Enterobacteriaceae strains isolated in the Unit of Microbiology of the Great Romagna Hub Laboratory. METHODS: All the colistin resistant Enterobacteriaceae, isolated from August 1st 2016 to July 31st 2017, were prospectively evaluated for mcr-1 and mcr-2. Backdated survey of mcr 3, mcr-4 and mcr-5 was performed on the same group of isolates. Species identification was achieved by Vitek MS and the antibiotic susceptibility testing was performed both with Vitek-2 and Sensititre systems. Colistin resistant isolates were screened by PCR for the presence of the plasmid-mediated colistin resistance genes and amplicons were verified by sequencing. All mcr-1 positive isolates were subjected to MLST analysis. RESULTS: Over the total of 19053 isolates belonging to Enterobacteriaceae, 90 were colistin resistant. The presence of mcr-1 was detected in 26 Escherichia coli. The overall prevalence of mcr-1 was 0.14%. The mcr-1 positive E. coli strains were assigned to 13 distinct sequence types (STs) according to MLST. CONCLUSIONS: The prospective epidemiological survey carried out in our study gave a glimpse of the plasmid mediated colistin resistance dissemination in Romagna. Since the prevalence rate of carbapenem resistant Enterobacteriaceae (CRE) in some hospital wards in our area is alarming, we underline the importance of a Surveillance Program to monitor the spread of the plasmid-mediated colistin resistance genes into MDR Gram-negative bacteria. PMID- 29447915 TI - Comparing Treatment of Acute Retinal Necrosis With Either Oral Valacyclovir or Intravenous Acyclovir. AB - PURPOSE: To compare the visual outcomes of patients with acute retinal necrosis (ARN) treated initially with intravenous acyclovir vs oral valacyclovir therapy. DESIGN: Retrospective, comparative, interventional case series. METHODS: Sixty two patients (68 eyes) with ARN, treated at Moorfields Eye Hospital (United Kingdom) between 1992 and 2016, were identified through the hospital's electronic database. Exclusion criteria included insufficient patient records or follow-up (<150 days). Fifty-six patients had unilateral ARN, while 6 had bilateral ARN. Patients who received intravenous acyclovir on diagnosis (n = 33) were compared with patients treated with oral valacyclovir (n = 29) across outcomes including best-corrected visual acuity, retinal detachment, severe vision loss, and other complications. The impact of adjunctive intravitreal antiviral and prophylactic barrier laser treatment was also assessed. RESULTS: Change in best-corrected visual acuity was not significantly different for eyes treated initially with intravenous therapy vs oral therapy over 5 years of follow-up data (P = .16). There was no difference in the rates of severe vision loss between the 2 groups (46% and 59%, respectively, P = .18), or of those eyes retaining good vision (28% vs 31%, respectively, P = .80). Retinal detachment occurred in 63% of cases and did not differ across treatment groups (62% vs 66%, respectively, P = .67). Barrier laser and intravitreal therapy had no effect on retinal detachment rate in either group. CONCLUSION: Oral valacyclovir is clinically equivalent to intravenous therapy in the management of ARN. Oral valacyclovir as an outpatient therapy-with or without intravitreal foscarnet-can therefore be considered as an acceptable alternative to inpatient therapy required for intravenous treatment. PMID- 29447914 TI - Progression of Primary Open-Angle Glaucoma in Diabetic and Nondiabetic Patients. AB - PURPOSE: To compare the rates of visual field (VF) loss and retinal nerve fiber layer (RNFL) thinning in primary open-angle glaucoma (POAG) patients with or without type 2 diabetes mellitus (DM). DESIGN: Cohort study. METHODS: A total of 197 eyes (55 eyes of 32 POAG patients with DM in POAG/DM group and 142 eyes of 111 age-matched POAG patients without DM in POAG/DM- group) were included from the Diagnostic Innovations in Glaucoma Study (DIGS). Type 2 DM participants were defined by self-report of DM history and use of antidiabetic medication. The rates of VF loss and RNFL loss were compared in POAG eyes with and without DM using univariate and multivariable mixed-effects models. RESULTS: The median (interquartile range) follow-up was 5.7 years (4.0, 6.4). The mean rate of global RNFL loss in the POAG/DM group was 2-fold slower than in the POAG/DM- group overall (-0.40 MUm/year vs -0.83 MUm/year, respectively P = .01). Although a slower rate of VF mean deviation and pattern standard deviation loss was found in the POAG/DM group compared to the POAG/DM- group, the difference was not statistically significant. CONCLUSIONS: POAG patients with treated type 2 DM, who had no detectable diabetic retinopathy, had significantly slower rates of RNFL thinning compared to those without diagnosed DM.

Membrane proteins, vital to many biological functions and implicated in numerous diseases, fold into their active conformations in the complex environment of the cell bilayer membrane. While many membrane proteins rely on the translocon and chaperone proteins to fold correctly, others can achieve their functional form in the absence of any translation apparatus or other aides. Nevertheless, the spontaneous folding process is not well understood at the molecular level. Recent findings suggest that helix fraying and loop formation may be important for overall structure, dynamics and regulation of function. Several types of membrane helices with ionizable amino acids change their topology with pH. Additionally we note that some peptides, including many that are rich in arginine, and a particular analogue of gramicidin, are able passively to translocate across cell membranes. The findings indicate that a final protein structure in a lipid bilayer membrane is sequence-based, with lipids contributing to stability and regulation. While much progress has been made toward understanding the folding process for alpha-helical membrane proteins, it remains a work in progress.

AB - Since cancer cells depend on de novo lipogenesis for energy supply, highly active membrane biosynthesis and signaling, enhanced fatty acid synthesis is a crucial characteristic of cancer cells. Hence, targeting lipogenic enzymes and signaling cascades is a very promising approach in developing innovative therapeutic agents for the fight against cancer. This review summarizes main aspects of altered fatty acid synthesis in cancer cells and emphasizes the power of chemical genetic approaches in identifying and analyzing novel anti-cancer drug candidates interfering with lipid metabolism.

AB - The envelope (E) protein of Dengue virus rearranges to a trimeric hairpin to mediate fusion of the viral and target membranes, which is essential for infectivity. Insertion of E into the target membrane serves to anchor E and possibly also to disrupt local order within the membrane. Both aspects are likely to be affected by the depth of insertion, orientation of the trimer with respect to the membrane normal, and the interactions that form between trimer and membrane. In the present work, we resolved the depth of insertion, the tilt angle, and the fundamental interactions for the soluble portion of Dengue E trimers (sE) associated with planar lipid bilayer membranes of various combinations of 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC), 1 palmitoyl-2-oleoyl-sn-glycero-3-phospho-rac-glycerol (POPG), 1-palmitoyl-2-oleoyl sn-glycero-3-phosphoethanolamine (POPE), and cholesterol (CHOL) by neutron reflectivity (NR) and by molecular dynamics (MD) simulations. The results show that the tip of E containing the fusion loop (FL) is located at the interface of the headgroups and acyl chains of the outer leaflet of the lipid bilayers, in good agreement with prior predictions. The results also indicate that E tilts with respect to the membrane normal upon insertion, promoted by either the anionic lipid POPG or CHOL. The simulations show that tilting of the protein correlates with hydrogen bond formation between lysines and arginines located on the sides of the trimer close to the tip (K246, K247, and R73) and nearby lipid headgroups. These hydrogen bonds provide a major contribution to the membrane anchoring and may help to destabilize the target membrane.

AB - Programmed cell death protein 1 (PD-1) and indoleamine 2,3-dioxygenase (IDO) are both immunosuppressive proteins. Here, we investigated the relationship between PD-1 and IDO in the tumor microenvironment (TME) and in tumor-draining lymph nodes (TDLNs) in breast cancer patients. First, the protein and mRNA expression levels of PD-1 and IDO in 20 frozen tissues were examined using Western blotting and real-time polymerase chain reaction. Second, 151 paraffin-embedded breast samples and 52 lymph node samples were analyzed by immunohistochemistry. Third, correlation and survival data for PD-1 and IDO in 963 breast tumor patients were mined using the cBio Cancer Genomics Portal. We found that the protein expression level of IDO was significantly increased in frozen tumor tissues (P = .005). From paraffin-embedded samples in the TME, PD-1+ cells were only located in the stroma, while IDO was expressed in myoepithelial, stromal, and tumor cells. PD-1 and stromal IDO in the TME showed increased expression in tumors (P< .001 and P < .001, respectively). In TDLNs, PD-1+ cells were primarily located in the germinal centers (GCs), and IDO+ cells were primarily located in the paracortex. Normal lymph nodes expressed PD-1 and IDO at the same level as non-metastatic and metastatic lymph nodes (P = .151 and P = .812, respectively). According to cBioPortal, the correlation analysis showed that IDO and PD-1 had high correlation coefficients (r = 0.83). These findings suggest that there is a positive correlation between the expression of PD-1 and IDO and that blocking both PD-1 and IDO pathways may represent an attractive therapeutic strategy in breast cancer treatment. PMID- 29447920 TI - Overexpression of BCAT1 is a prognostic marker in gastric cancer. AB - As one form of branched-chain amino-acid transaminase (BCAT) enzymes, It has been found that up-regulation of BCAT1 is associated with poor prognosis in numerous types of tumors, but studies on the role of BCAT1 expression in gastric cancer (GC) are rare. The aims of this study were to detect BCAT1 expression in GC and to analyze its association with prognosis of GC patients. Microarray experiments were performed on the Affymetrix U133 plus 2.0 GeneChip Array. The protein and messenger RNA levels of BCAT1 were validated by immunohistochemistry and real time quantitative polymerase chain reaction in GC tissues and adjacent noncancerous tissues. Our study shows that the expression of BCAT1 significantly increased in human GC. Furthermore, it can also be found that BCAT1 overexpression was associated with TNM stage (P < .05), local invasion (P < .05), Lauren type (P < .05), tumor classification (P < .05), lymph node metastasis (P < .05), and presence of distant metastasis (P < .05). Kaplan-Meier survival analysis revealed that high BCAT1 expression predicted significantly worse overall survival (P < .05), whereas multivariate Cox regression analysis showed that BCAT1 affects GC independently. In conclusion, up-regulation of BCAT1 indicated a poor survival rate of GC and may serve as a useful marker for predicting the outcome of patients with GC. PMID- 29447921 TI - DNA demethylation of claudin-4 suppresses migration and invasion in laryngeal squamous carcinoma cells. AB - Claudin-4 (CLDN4) is a member of the claudin transmembrane protein family, which consists of integral membrane proteins that are components of the epithelial cell tight junctions; these tight junctions regulate movement of solutes and ions through the paracellular space. CLDN4 is also a differentiation marker and is believed to indicate an epithelial phenotype. However, the role of CLDN4 in laryngeal squamous carcinoma is still unclear. Here, we showed that CLDN4 expression was down-regulated in laryngeal squamous carcinoma tissues and negatively correlated with methyl-CpG-binding protein 2. In addition, CLDN4 was hypermethylated in HEp-2 cells. DNA demethylation of CLDN4 by 5-aza-2' deoxycytidine suppressed migration and invasion of HEp-2 cells, whereas CLDN4 silencing restored the migration and invasion of HEp-2 cells. Therefore, CLDN4 plays a key role in laryngeal squamous carcinoma progression. PMID- 29447922 TI - Regional lymph node sampling in lung carcinoma: a single institutional and national database comparison. AB - Assessing regional lymph node metastasis is a key component of lung carcinoma staging and prognostication. Recent guidelines have suggested a quality metric of 10 total regional lymph nodes sampled with each stage I-II primary lung carcinoma resection. However, the extent of mediastinal lymph node sampling remains controversial. We assessed factors contributing to regional lymph node counts and effect on overall patient survival in an institutional cohort of 888 cases and the Surveillance, Epidemiology, and End Results national cancer registry (10 856 cases). The distribution of total lymph node counts in lobectomy and pneumonectomy cases was variable with a median of 10 and an interquartile range of 7 to 14. Multiple clinical and pathologic factors correlated with total regional node counts. Total lymph node counts of at least 10 in the institutional cohort did not correlate with significant differences in overall survival as compared with node counts of less than 10 (P = .38). In the Surveillance, Epidemiology, and End Results database, although 0 regional lymph nodes were correlated with reduced overall survival (hazard ratio, 1.47; P < .01), no significant difference was detected for 1 to 9 versus at least 10 nodes (P = .8). In conclusion, lymph node counts for primary lung carcinoma are driven by surgical, pathologic, and biologic variability. We find no evidence for a meaningful quality metric of 10 total regional lymph nodes at the institutional and national registry levels. PMID- 29447923 TI - The significance of tumor budding in T1 colorectal carcinoma: the most reliable predictor of lymph node metastasis especially in endoscopically resected T1 colorectal carcinoma. AB - Endoscopic resection is widely recognized as a first-line treatment for T1 colorectal cancers (CRC), although additional surgical intervention may be indicated based on the risk of lymph node (LN) metastasis. However, risk factors for LN metastasis in T1 CRC not fully established. We investigated the clinicopathological features of T1 CRC and evaluated their association with lymph node metastasis in 133 cases of T1 CRC, consisting of 87 cases with first-line endoscopic resection (EMR) followed by additional surgery and 46 cases with primary surgical resection. Among the total 133 cases, 16 cases (12.0%) showed LN metastasis; 13 cases (13/16, 81.25%) were included in endoscopic resection cohort. These were all of the non-pedunculated gross type and most of LN+ tumors invaded submucosa over 1000 MUm (surgical cohort versus endoscopic resection cohort; 3 versus 11). However, there was no statistical difference in the depth of submucosal invasion between the LN+ and LN- in both surgical cohort (2799.42 MUm +/- 401.56 versus 3000.00 MUm +/- 721.69, P = .897) and endoscopic resection cohort (2066.55 MUm +/- 142.96 versus 2305.77 MUm +/- 345.62, P = .520). Conversely, presence of and a higher number of tumor budding foci were associated with an increase in the incidence of LN metastasis in both cohort (P < .0001). Positive resection margins as well as absence of adenoma component were also an independent predictive factor for lymph node metastasis in 87 cases with first line endoscopic resection followed by additional surgery. We found that tumor budding was the most reliable LN metastasis predictor in T1 CRC in both surgically resected and endoscopic resection specimens. PMID- 29447924 TI - New prostate cancer grade grouping system predicts survival after radical prostatectomy. PMID- 29447925 TI - DJ-1 is a useful biomarker for invasive extrahepatic cholangiocarcinoma. AB - We have previously reported that DJ-1 protein is up-regulated in cholangiocarcinoma compared with non-neoplastic epithelium of the bile duct in a study using liquid-chromatography mass spectrometry-based proteomics. The aim of this study was to clarify whether DJ-1 expression offers a biomarker for patients with invasive extrahepatic cholangiocarcinoma (EHCC) who undergo surgical resection with curative intent. Positive immunohistochemical (IHC) staining of DJ 1 was significantly more frequent in the cytoplasm of 96 invasive EHCCs (n = 28, 29.2%) than in that of 66 non-neoplastic epithelial lesions adjacent to invasive EHCC (n = 7, 10.6%; P = .006). No significant difference in clinicopathological features was evident between invasive EHCC patients with negative (n = 68) and positive (n = 28) IHC staining. However, negative IHC staining for DJ-1 in cytoplasm was selected as an independent risk factor for adverse prognosis on multivariate analysis (P = .004, hazard ratio 2.13, 95% confidence interval 1.28 3.57). Serum levels of DJ-1 in 16 invasive EHCC patients with metastasis were compared with 12 invasive EHCC patients without metastasis. Serum levels of DJ-1 tended to be higher in 16 patients with metastasis (median, 40.9 ng/ml) than in 12 patients without (27.6 ng/ml, P = .137). In addition, patients with high serum levels (>= 40 ng/ml) of DJ-1 tended to have metastasis more frequently than those without (P = .054, Fisher's exact test). We concluded that IHC staining pattern and serum level of DJ-1 in patients with invasive EHCC might be predictive of prognosis and metastasis, respectively. PMID- 29447927 TI - Impact of exposure factor selection on deterministic consumer exposure assessment. AB - Deterministic exposure assessment has uncertainty about the selection of input parameters on the resulting estimates. The purpose of this study was to compare inhalation exposures estimated by a specific percentile of each of the three exposure factors in deterministic assessment with population exposure. Exposure to nine household care products, namely a deodorizer, six cleaning products, and two disinfectants were investigated. The population exposures were individually calculated for three exposure factors (frequency of use, amount of use, and duration of use) from an existing database of 3333 participants representing the national population. Deterministic exposure assessment was conducted according to various percentiles of exposure factors. 99th percentiles of population exposure in all nine consumer products were 1.3-2.4 times greater than the 95th percentiles. Inhalation exposures based on the 75th percentiles of each of the three exposure factors in deterministic assessment were much lower than the 95th percentiles of the population exposure. Deterministic exposure estimates using 85th to 99th percentiles of each of the three exposure factors were closer to the 95th percentiles of the population exposure. We concluded that exposure factors in deterministic assessment should be greater than the 75th percentile to more precisely estimate exposure of at-risk groups. PMID- 29447926 TI - The role of physical activity enjoyment in the pathways from the social and physical environments to physical activity of early adolescent girls. AB - Most girls experience a notable decline in physical activity (PA) in early adolescence, increasing their risk for harmful health outcomes. Enjoyment for PA (i.e., positive feelings toward PA) is a determinant of PA among girls during adolescence and sustained PA throughout adulthood. Previous studies recommended increasing girls' PA enjoyment in order to increase their PA, but did not include environmental-level strategies for how families, schools, or communities do this. To gain insight on such strategies, this study examines the role of PA enjoyment as a mediator of social and physical environments to moderate-to-vigorous intensity PA of early adolescent girls. Cross-sectional, secondary analyses, using structural equation modeling, were conducted on a U.S. national dataset of 1721 sixth grade girls from the Trial of Activity for Adolescent Girls in 2003. Mediation model fit parameters included chi2 (292, N = 1721) = 947.73 p < 0.001, CFI = 0.95, RMSEA = 0.04 (90% CI = 0.03, 0.04), and SRMR = 0.037 suggesting overall good fit. There were no indirect effects on PA through PA enjoyment from the social or physical environmental factors. To PA, there were significant direct effects only from social support from friends (beta = 0.15, CI = 0.09, 0.22). To PA enjoyment, there were significant direct effects from social support from family (beta = 0.15, CI = 0.08, 0.23), school climate (teachers beta = 0.15, CI = 0.10, 0.21 and boys beta = 0.15, CI = 0.09, 0.20), and neighborhood environment (beta = 0.10, CI = 0.04, 0.17). The findings of this study identified several direct effects of the social and physical environment on PA enjoyment that can begin to inform environmental-level strategies for increasing PA enjoyment among early adolescent girls. PMID- 29447928 TI - The use of polysulfated polysaccharides heparin like compounds, glycosaminoglycans and Vitamin B17 as a possible treatment for prostate cancer. AB - Prostate cancer is impacting many men globally. It is a disease that has no effective treatment is available in the market. The understanding of the biophysical and biochemical aspects of the disease and the mechanism that allow it to metastasize is key to finding an effect treatment. Maintenance or pretreatment drug as well as a post treatment drug can be effective to avoid or delay the disease from appearing. The polysaccharides and monosaccharides polymers combined with vitamins can be the ingredient to developing the treatment. There are many evidences that investigators examined the individual components of the therapy proposed but never a combination of all these therapies. The one item that is not discussed is how to formulate the ingredient into an effective form which is a proprietary work being conducted currently. Nevertheless, the hypothesis seems reasonable to us and worth sharing with the scientific community. PMID- 29447929 TI - A complex systems approach to cancer prevention. AB - Cancer incidence continues to be a major health problem possibly because cancer is a complex system comprising many agents that interact in a non-linear manner resulting in many possible outcomes. The degree of complexity of a cancer system could be vast involving multiple endogenous and exogenous agents interacting with the over 10 trillion cells comprising the body. It is hypothesized that the practical management of this complexity may be a key to cancer prevention and possibly treatment. But the management and resolution of such an immensely complex system is difficult and may require a multidisciplinary approach including physics, biology, biochemistry and medical science. Research such as in systems biology involving large data sets may offer resolution in time, but the scale of the task is daunting. In evaluating the hypothesis, this paper proposes a method of resolution of the complex cancer system through a proxy in the form of the vital body system, energy balance, involved in several cancer processes. Although I suggest that the energy balance system is itself complex, it may permit access to factors that may be used in limiting cancer initiation. Meta analysis related to factors of blood sugar, inflammation, stress and immune response reveal that they could be likely candidates for management. Analysis also reveals certain devices that may give practical effect to these management options. Due to the inherent complexity of a cancer system, multiple devices may need to be applied in a combination. The analysis suggests that the low-risk and low-cost devices metformin, vitamin D and vitamin C, may prove to be suitable for use as a practical cancer prevention strategy. If the presented hypothesis is correct, a practical method for prevention or management of cancer may be possible. A trial to test the hypothesis is proposed. PMID- 29447930 TI - Linked help from bacterial proteins drives autoantibody production in small vessel vasculitis. AB - The small vessel vasculitides granulomatosis with polyangiitis (GPA) and microscopic polyangiitis are associated with autoantibodies to neutrophil cytoplasm antigens (ANCA), principally proteinase-3 (PR3) and myeloperoxidase (MPO). There is an association between GPA and nasal carriage of Staphylococcus aureus. The recent finding that S. aureus produces proteins that bind tightly to and block the function of both PR3 and MPO suggests a mechanism for ANCA formation. The bacterial protein-autoantigen conjugate is recognised by B cells with ANCA specificity, internalised, and the bacterial protein processed and presented to T cells with specificity for bacterial peptides. The T cell can then provide help to the B cell, allowing class switching, affinity maturation and the production of pathogenic ANCA. This mechanism predicts that T cells with this specificity will be found in patients, and that the bacterial protein-autoantigen conjugate will be particularly efficient at eliciting ANCA production. PMID- 29447931 TI - Impulsive mechanisms influencing relapse in alcohol drinking. AB - Impulsivity has been related to different features of addictive behaviors. Growing data, generated in separated lines of research, suggest that different processes underlying impulsivity are associated to relapse in alcohol drinking. Considering the evidence, relapse can be understood as an impulsive choice or as an impulsive action. In the first case, the return to drinking behavior is a consequence of insensitive to delayed consequence, that is, to the discounting of delayed rewards. In the second case, relapse is a consequence of failures to inhibit prepotent responses. Nevertheless, conditions that control the action of each mechanism or their interaction to influence relapse still unknown. We hypothesize that both mechanisms interact to produce relapse depending on framing effects, the moments of a drinking episode or context. The implication of the hypothesis is that relapse prevention strategies need to reduce discounting rate, but also to increase behavioral inhibition in the presence of cues related to alcohol. PMID- 29447932 TI - Determining the venous oxygen reservoir: A novel, hypothetical approach to titration of supplemental oxygen in preterm newborns. AB - While normal oxygen saturation is commonly thought to be a marker of normal oxygenation, cutaneous saturation does not account for the sufficiency of oxygen within each cell or that of the system overall. Rather, cutaneous oximetry simply defines the saturation of haemoglobin (Hb) with oxygen in a pulsatile vessel. Assessment of sufficiency is best determined by measurement of the amount of oxygen left over following aerobic respiration. This left over oxygen is 'stored' on Hb in the venous compartment and can be calculated as the venous oxygen content. We hypothesize that the development of a venous oxygen content or saturation reference range in a group of well, uninjured very preterm newborns and subsequent application, in a randomised trial, with a structural, functional and molecular outcome will resolve the method for assessment of oxygen sufficiency in preterms by demonstrating both clinical safety and effectiveness. This method could be subsequently used for titration of supplemental oxygen. PMID- 29447933 TI - Ultrasound-guided percutaneous electrolysis: A new therapeutic option for mammary fistulas. AB - Mammary fistula (MF) is a recurrent condition characterised by the draining of abscesses around the areola. The best management for MF remains challenging. Moreover, the main problem is the high recurrence rate of this disease. MF is considered a chronic process. The percutaneous electrolysis (PE) technique involves the application of a galvanic current with an ultrasound-guided needle to induce ablation and repair of the affected tissue. Good results have been obtained with PE in chronic tendinopathies. Below we present a hypothesis that PE may be a new therapeutic option for MF. PMID- 29447934 TI - Mismatch between GLUTs and glucose levels causes neuronal damage during glucose fluctuations. AB - Abnormal glucose levels damage the central nervous system, especially in case of rapid fluctuations. Even a single episode of glucose reperfusion can result in overt impairment of neurons. Oxidative stress plays an important role in this process, sharing properties with the pathophysiologic changes of glucose neurotoxicity. Glucose transporters (GLUTs) located in the brain are involved in direct glucose uptake by neurons. Instead of being insulin-sensitive, these transporters are regulated by glucose levels in the extracellular fluid, increasing their expression while glucose levels fall, to absorb more glucose. Therefore, we hypothesized that mismatch between altered GLUTs and sudden glucose level changes is responsible for neuronal damage during glucose fluctuations. Modulating hypoglycemia by increasing blood glucose slowly may improve the neurological outcomes of hypoglycemia. PMID- 29447935 TI - Biofilms busters to improve the detection of Borrelia using PCR. AB - Lyme disease is an affection caused by a spirochete infection called Borrelia Burgdorferi which may harbor a varied and misleading clinical symptomatology. The serology tests commonly used for diagnosis show a wide sensitivity varying from 34% to 70,5%, leaving many infected patients with false negative tests. Alternative techniques such as polymerase chain reaction (PCR) could be helpful but not conclusive enough. Using biofilm busters, such as stevia and serratiopeptidase, could lead to bacterial blood release, thus increasing the spirochete load, making PCR test more sensitive, thus improving the patient's diagnosis and management. PMID- 29447936 TI - Inducing hypertrophic effects of type I skeletal muscle fibers: A hypothetical role of time under load in resistance training aimed at muscular hypertrophy. AB - An emerging body of evidence is starting to suggest that the hypertrophy of skeletal muscle fibers might be load specific. In other words, it may be that resistance training with high loads (i.e., >=60% of 1 repetition maximum [RM]) emphasizes a greater growth of type II muscle fibers, while resistance training with low loads (i.e., <60% of 1RM) might primarily augment hypertrophy of type I muscle fibers. Type I and type II muscle fibers possess certain distinct characteristics, with type II muscle fibers having faster calcium kinetics, faster shortening velocities, and ability to generate more power than type I muscle fibers. Alternatively, compared to type II fibers, type I muscle fibers have a higher oxidative capacity and a higher fatigue threshold. Due to the lower fatigability of type I muscle fibers, it may be hypothesized that a greater time under load is necessary to stimulate an accentuated growth of these fibers. An increase in time under load can be achieved when training with lower loads (e.g., 30% of 1RM) and to momentary muscular failure. The present paper discusses the hypothesis that a greater hypertrophy of type I muscle fibers may be induced with low load resistance training. PMID- 29447937 TI - Splenectomy may have more complications than currently proven. AB - The spleen has been one of the least understood major organs for centuries. Its significance is relatively well-known today but it seems that all aspects of its activities are not fully understood. Persian medicine (PM) has special views on the function of spleen; many side effects were reported in PM due to spleen dysfunction. On the other hand nowadays splenectomy as a treatment strategy is recommended for some disorders and increasing risk of infections is considered as the most important long term side effect of that. In this study, we hypothesize that splenectomy may have more side effects than currently proven. According to PM, spleen is in close connection with liver, cardiovascular system, stomach, bone, brain and skin, and that is why any kind of spleen dysfunction leads to change in blood viscosity, appetite and bone strength, liver dysfunction, mood and skin disorders, cancer formation and fever. Considering this viewpoint it can be hypothesized such side effects may also occur after splenectomy. Proven complications of splenectomy include hypercoagulated state, cardiovascular events and infectious diseases but there is also some evidence about increased risk of cancer, skin disease like systemic lupus erythematosus, mood disorder such as depression, defective bone formation and impairment of immunity which can be considered as different levels of evidence to confirm the hypothesis. But for some others such as changes in appetite, there are no studies let alone convincing evidence. Future research about theses possible complications may lead to novel results. PMID- 29447938 TI - Hypothesis: Is there a link between the immune response to Human Herpes Virus type 6Alpha (HHV-6Alpha) infection and the interaction network (interactome) of the genes encoding the CTSS, PTX3, CHI3L1, Mx1, CXCL16, BIRC3 and BST2 proteins? AB - Human Herpes Virus type 6 (HHV-6) is a ubiquitous virus consisting of two viral species, HHV-6A and HHV-6B that have been associated with numerous and diverse pathologies. As many other viruses HHV-6 modulates the apoptotic machinery of its host to subvert immune response to infection, yet the exact mechanisms behind this process remain under investigation. The genes encoding the CTSS, PTX3, CHI3L1, Mx1, CXCL16, BIRC3 and BST2 proteins have been linked to HHV-6Alpha related neurologic diseases whilst also associated with apoptosis. This study aimed at the identification and functional analysis of the gene interaction network (interactome) of CTSS-PTX3-CHI3L1-Mx1-CXCL16-BIRC3-BST2 so as to evaluate the hypothesis of a probable link between the latter and host's immune response to HHV-6A infection. PMID- 29447939 TI - The cardiovascular robustness hypothesis: Unmasking young adults' hidden risk for premature cardiovascular death. AB - An undetected high risk for premature death of cardiovascular disease (CVD) among individuals with low-to-moderate risk factor levels is an acknowledged obstacle to CVD prevention. In this paper, we present the hypothesis that the vasculature's robustness against risk factor load will complement conventional risk factor models as a novel stratifier of risk. Figuratively speaking, mortality risk prediction without robustness scoring is akin to predicting the breaking risk of a lake's ice sheet considering load only while disregarding the sheet's bearing strength. Taking the cue from systems biology, which defines robustness as the ability to maintain function against internal and external challenges, we develop a robustness score from the physical parameters that comprehensively quantitate cardiovascular function. We derive the functional parameters using a recently introduced novel system, VascAssist 2 (iSYMED GmbH, Butzbach, Germany). VascAssist 2 (VA) applies the electronic-hydraulic analogy to a digital model of the arterial tree, replicating non-invasively acquired pule pressure waves by modulating the electronic equivalents of the physical parameters that describe in vivo arterial hemodynamics. As the latter is also subject to aging-associated degeneration which (a) progresses at inter individually different rates, and which (b) affects the biomarker-mortality association, we express the robustness score as a correction factor to calendar age (CA), the dominant risk factor in all CVD risk factor models. We then propose a method for the validation of the score against known time-to-event data in reference populations. Our conceptualization of robustness implies that risk factor-challenged individuals with low robustness scores will face preferential elimination from the population resulting in a significant robustness-CA correlation in this strata absent in the unchallenged stratum. Hence, we also present an outline of a cross-sectional study design suitable to test this hypothesis. We finally discuss the objections that may validly be raised against our robustness hypothesis, and how available evidence encourages us to refute these objections. PMID- 29447940 TI - The relationship between plasma vascular endothelial growth factor and erythrocyte 2,3-bisphosphoglycerate: The putative role of chronic hypoxia. AB - The non-invasive assessment of chronic tissue hypoxia is difficult. Pulse oximetry only allows the peripheral oxygen saturation to be measured, while the detection of hyperlactataemia needs to take into account the fact that the accumulation of lactic acid may result from several causes other than prolonged tissue hypoxia. Arterial blood oxygen measurement is invasive and often does not give a good indication of the level of tissue hypoxia. Other suggested methods include the use of positron emission tomography, magnetic resonance T2* relaxation time measurement, photoacoustics and high-frequency ultrasound. Tissue hypoxia leads to increased levels of hypoxia-inducible factor-1alpha, which in turn upregulates VEGFA, leading to increased levels of vascular endothelial growth factor (VEGF), which promote angiogenesis. Hypoxia lasting for more than a few hours is associated with increased synthesis in erythrocytes of 2,3 bisphosphoglycerate (BPG), a powerful regulator of the allosteric properties of haemoglobin, via the Rapoport-Luebering phosphoglycerate cycle. We therefore hypothesised that plasma VEGF and erythrocyte BPG levels should be positively correlated. Venous blood samples from 34 patients (18 male, mean age (standard error) 43.4 (3.2) y) were analysed; plasma VEGF was measured using an enzyme linked immunosorbent assay while the erythrocyte BPG was assessed by quantitative Fourier transform infrared spectrometry following gel electrophoresis. The Pearson product-moment correlation between the two variables was 0.622 (p < 0.0001). Based on our findings, we suggest that it may be useful to measure both erythrocyte BPG and plasma VEGF, together, when assessing chronic hypoxia; elevated levels of both are likely to indicate hypoxia.

AB - L-Asparaginases (ASNase) belong to a family of amidohydrolases, have both asparaginase and glutaminase activity. Acute lymphocytic leukemia (ALL) is an outrageous disease worldwide. Bacterial ASNase has been used for the treatment of ALL. Glutaminase activity of enzyme causes some side effect and it is not essential for anticancer activity. The aim of this study was engineering of Escherichia coli asparaginase II to find a mutant with reduced glutaminase activity by molecular docking, molecular dynamics (MD) and QM-MM (Quantum mechanics molecular dynamics) simulations. Residues with low free energy of binding to Asn and high free binding energy to Gln were chosen for mutagenesis. Then, a mutant with higher glutaminase free binding energy was selected for further studies. Additionally, the MD simulation and QM-MM computation of wild type (WT) were employed and the selected mutated ASNase were analyzed and discussed. Our data showed that V27T is a good candidate to reduction the glutaminase activity, while has no remarkable effect on asparaginase activity of the enzyme. The simulation analysis revealed that V27T mutant is more stable than WT and mutant simulation was successful completely. QM-MM results confirmed the successfulness of our mutagenesis.

AB - Chronic cerebral hypoperfusion (CCH), a leading cause of various cerebrovascular diseases, leads to cognitive dysfunction due to neuron loss and impaired neurogenesis. Liver X receptors (LXRs), including LXRalpha and LXRbeta isoforms, are crucial for cholesterol metabolism, synaptic plasticity as well as neurogenesis. However, it is not clear the potential roles of LXRs in the pathogenesis of cognitive impairment induced by CCH. In this study, we demonstrated that LXRbeta expression decreased in hippocampus of CCH mice. GW3965, a synthetic dual agonist for both LXRalpha and LXRbeta, ameliorated impairment of learning and memory in CCH mice by promoting neuronal survival and neural stem cells (NSCs) proliferation in dentate gyrus (DG) of CCH mice. The proliferative effects of GW3965 were further confirmed in cultured neural progenitor cells (NPCs) and showed in a concentration-dependent manner. Moreover, GW3965 phosphorylated protein kinase B (Akt) at Ser473 in a time- and concentration-dependent manner in NPCs. Furthermore, both LY294002, an inhibitor for phosphoinositide-3-kinase (PI3K), and short hairpin RNAs for LXRbeta knockdown, abrogated GW3965-induced Akt phosphorylation, and therefore abolished GW3965-mediated proliferation-promoting of NPCs. All the data suggested that GW3965 ameliorated impaired cognitive functions in CCH by promoting NSC proliferation through PI3K/Akt pathway followed LXRbeta activation. This study correlates a deficit of LXRbeta in cognitive dysfunction in CCH with impaired neurogenesis in hippocampus, and LXRs may serve as a potential therapeutic target for chronic cerebral ischemia. PMID- 29447945 TI - Salmeterol, agonist of beta2-aderenergic receptor, prevents systemic inflammation via inhibiting NLRP3 inflammasome. AB - beta2-Aderenergic receptor (beta2AR) agonist, Salmeterol exhibits anti inflammatory activities. However, the inhibitory effects of Salmeterol on inflammasome activation are elusive and the underlying mechanisms need to be explored. In this study, we established inflammatory model in primary bone marrow derived macrophages (BMDM) from C57BL/6J mice and beta-arrestin2 knockout (beta arrestin2-/-) mice in vitro. In vivo study by LPS intraperitoneally (i.p.) in C57BL/6J mice was carried out to ascertain its roles in systemic inflammation. We found that Salmeterol (10-10 M-10-7 M) prevented the cleavage of caspase-1 and the activation of NLRP3 inflammasome, reduced the release of pro-inflammatory cytokines tumor necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL 1beta) in vitro. Blockade of adenosine3',5'cyclic monophosphate (cAMP)/protein kinase A (PKA) pathway with cAMP or PKA inhibitors inhibited anti-inflammatory effects of Salmeterol only at 10-7 M. Depletion of beta-arrestin2 compromised the inhibitory effects of Salmeterol at both 10-10 M and 10-7 M. Salmeterol increased the interaction of beta-arrestin2 and NLRP3. In vivo study showed that Salmeterol decreased the serum concentrations of pro-inflammatory cytokines IL-1beta and TNF alpha, blocked cleavage of caspase-1 and release of IL-1beta in BMDM. These findings imply that Salmeterol at low concentrations (10-10 M-10-7 M) shows anti inflammatory effect via inhibiting NLRP3 inflammasome. The underlying mechanisms is dosage-dependent: Salmeterol at 10-10 M shows anti-inflammatory effects through beta-arrestin2 pathway, and 10-7 M Salmeterol inhibits inflammation via both classical G-protein coupled receptor (GPCR)/cAMP pathway and beta-arrestin2 pathway. These results provide new ideas for the future treatment of systemic inflammation and other inflammatory diseases. PMID- 29447946 TI - Bladder Re-augmentation in Classic Bladder Exstrophy: Risk Factors and Prevention. AB - OBJECTIVE: To characterize the causes of re-augmentation in patients with classic bladder exstrophy (CBE). METHODS: A prospectively maintained institutional database of 1327 exstrophy-epispadias complex patients was reviewed for patients with CBE who underwent more than 1 augmentation cystoplasty (AC) procedure. Data regarding bladder capacities, complications following AC, and reasons for re augmentation were evaluated. RESULTS: A total of 166 patients with CBE underwent AC. Of these, 67 (40.4%) were included in the control group and 17 (10%) patients underwent a re-augmentation. There were several indications for re-augmentation including continued small bladder capacity (17 of 17), inadequate bladder necks (8 of 17), failed rattail augmentation (2 of 17), stomal incontinence (1 of 17), a urethrocutaneous fistula (1 of 17), and an hourglass augmentation (1 of 17). Of note, 5 of the 17 patients (29%) had a re-augmentation procedure with a ureteral reimplantation. The sigmoid colon was the most commonly used bowel segment in the failed initial AC (8 patients), whereas the ileum was the most commonly used segment during re-augmentation (12 patients). In the re-augmentation cohort, the mean amount of bowel used during the first AC procedure was 12 cm (standard deviation [SD] 3.6) compared with 19 cm (SD 5.0) during re-augmentation. The mean amount of bowel used for control group augmentations was 20.8 cm (SD 4). The mean re-augmentation preoperative bladder capacity of 100 mL (SD 60) immediately increased after re-augmentation to 180.8 mL (SD 56.4) (P = .0001). CONCLUSION: Bladder re-augmentation is most commonly required in the setting of a small bladder capacity after an initial AC, when an insufficient amount of bowel is used during the first AC procedure. PMID- 29447947 TI - 80-W GreenLight Laser Vaporization Versus Transurethral Resection of the Prostate for Treatment of Benign Prostatic Obstruction: 5-Year Outcomes of a Single-center Prospective Randomized Trial. AB - OBJECTIVE: To assess long term functional and safety follow-up data after 80-W GreenLight photoselective vaporization (GL PV) of the prostate and transurethral resection of the prostate (TURP). MATERIALS AND METHODS: Prospective randomized trial at a single tertiary referral center (Geneva, Switzerland). Patients were recruited in the outpatient clinic if they met the criteria for surgical treatment of benign prostatic obstruction. At baseline, 238 patients were treated either with the 80-W GL PV or monopolar TURP. After 5 years, data were available from 105 patients: 44 GL PV patients and 61 TURP patients. The primary outcome measure was the International Prostate Symptom Score (IPSS). Secondary outcome measures included maximum urinary flow rate (Qmax), postvoidal residual (PVR) and reoperation rate. Statistical analyses were performed using Stata 14 (StataCorp). RESULTS: After 5 years of follow-up, mean improvements in International Prostate Symptom Score, postvoidal residual and maximum urinary flow rate were similar in both groups. The re-treatment rate was 14.3% in the GL PV group vs 11.9% in the TURP group (P = .9). CONCLUSION: Noninferiority of the GL PV to TURP was confirmed in all functional and safety outcomes at 5-year follow-up. GL-PV could be a safe surgical alternative for patients suffering from benign prostatic obstruction. PMID- 29447948 TI - Roles of Ihh signaling in chondroprogenitor function in postnatal condylar cartilage. AB - Condylar articular cartilage in mouse temporomandibular joint develops from progenitor cells near the articulating surface that proliferate, undergo chondrogenesis and mature into hypertrophic chondrocytes. However, it remains unclear how these processes are regulated, particularly postnatally. Here we focused on the apical polymorphic layer rich in progenitors and asked whether the phenotype and fate of the cells require signaling by Indian hedgehog (Ihh) previously studied in developing long bones. In condyles in newborn mice, the apical polymorphic/progenitor cell layer was ~10 cell layer-thick and expressed the articular matrix marker Tenascin-C (Tn-C), and the underlying thick cell layer expressed Tn-C as well as the chondrogenic master regulator Sox9. By 1 month, condylar cartilage had gained its full width, but became thinner along its main longitudinal axis and displayed hypertrophic chondrocytes. By 3 months, articular cartilage consisted of a 2-3 cell layer-thick zone of superficial cells and chondroprogenitors expressing both Tn-C and Sox9 and a bottom zone of chondrocytes displaying vertical matrix septa. EdU cell tracing in juvenile mice revealed that conversion of chondroprogenitors into chondrocytes and hypertrophic chondrocytes required about 48 and 72 h, respectively. Notably, EdU injection in 3 month-old mice labeled both progenitors and maturing chondrocytes by 96 h. Conditional ablation of Ihh in juvenile/early adult mice compromised chondroprogenitor organization and function and led to reduced chondroprogenitor and chondrocyte proliferation. The phenotype of mutant condyles worsened over time as indicated by apoptotic chondrocyte incidence, ectopic chondrocyte hypertrophy, chondrocyte column derangement and subchondral bone deterioration. In micromass cultures of condylar apical cells, hedgehog (Hh) treatment stimulated chondrogenesis and alkaline phosphatase (APase) activity, while treatment with HhAntag inhibited both. Our findings indicate that the chondroprogenitor layer is continuously engaged in condylar growth postnatally and its organization and functioning depend on hedgehog signaling. PMID- 29447949 TI - Protective effects of Alpinae Oxyphyllae Fructus extracts on lipopolysaccharide induced animal model of Alzheimer's disease. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Alpinae Oxyphyllae Fructus (AOF) with warming and tonifying the kidney and spleen, anti-salivation, anti-polyuria and anti-diarrhea functions is the dried ripe fruits of Alpinia oxyphylla Miq. (Zingiberaceae). As a traditional Chinese medicine, its application history is very long. AIMS OF THE STUDY: The purpose of our study is to investigate the effects of different solvent extracts from AOF on lipopolysaccharide (LPS)-induced animal model of Alzheimer's disease (AD) to elucidate the traditional medical theories with modern pharmacological methods and provide a reference for further clarifying its active components and mechanisms. MATERIALS AND METHODS: The method of stepwise screening was adopted in this paper. The animals were divided into 9 groups, including control (CT) group, model (MD) group, donepezil (DPZ) group, total extract (TT) group, petroleum ether extract (PE) group, chloroform extract (CF) group, ethyl acetate extract (EA) group, n-butanol extract (NB) group and water extract (WT) group. The anti-amnesic effects of different solvent extracts from AOF were measured in LPS-induced memory deficits mice by Y maze test and Morris water maze (MWM) test. Hematoxylin eosin (HE) staining was applied to observe pathological changes in hippocampus and cerebral cortex tissue of different groups. Biochemical indicators including ionized calcium-binding adaptor molecule 1 (IBA-1), interleukin beta 1 (IL-1beta), Abeta1-42 and hyperphosphorylated tau proteins (p-tau) in hippocampus and cortex after treatment with LPS were measured according to the manufacturer's instructions of ELISA kits. HPLC was used to evaluate the major components of different extracts. RESULTS: It was found that successive intragastric administration of AOF (360 mg/kg) extracts for 14 days showed different degrees of improvement on LPS-induced AD model as measured by Y maze test, Morris water maze test, and Histopathological examination. Moreover, the results of ELISA suggested petroleum ether (PE) extracts were worth recommending for inhibiting the high level of IBA-1, IL-1beta, Abeta1-42 and p tau in hippocampus and cortex after treatment with LPS. CONCLUSIONS: The present study demonstrated for the first time that AOF attenuated LPS-induced learning and memory impairment, which may be associated with its inhibitory effect on neuroinflammation, amyloids-beta (Abeta) deposition and p-tau. This research provided a theoretical basis for elucidating the traditional theory of AOF, and was also the stepping stone to the next step. PMID- 29447950 TI - Ethnobotanical and ethnomedicinal studies in Baluchi tribes: A case study in Mt. Taftan, southeastern Iran. AB - ETHNOBOTANICAL RELEVANCE: From ancient times, the applied use of herbs has been common among indigenous people throughout the world. The present survey is a regional ethnobotanical study of Baluchi tribes living in the Mt. Taftan area, Sistan and Baluchistan Province, southeastern Iran. The aim of this study was to document all traditional knowledge and analyze the medicinal plants used in area and also to identify significant plant species for future pharmacological study. MATERIALS AND METHODS: Local knowledge was obtained through semi structured and open interviews, in which 51 informants were interviewed. Data were analyzed with Informant Agreement Relative (IAR) and Frequency of Citation (FC) indices. RESULTS: A total number of 106 taxa of medicinal plants were collected from ten villages from the surrounding plains and highlands of Mt. Taftan, out of 446 plant taxa collected or reported as native in the area. Most plants belong to the Irano-Turanian phytogeographical region in which Asteraceae (15%), Lamiaceae (11%), Fabaceae (8%), Rosaceae (7%), Apiaceae (7%) and Brassicaceae (5%) are those predominantly used. The regression analysis shows that families Apiaceae, Lamiaceae, Solanaceae and Rosaceae are more highly used as medicinal than species rich families such as Asteraceae and Fabaceae, which are the richest families in the Iranian flora. The highest FC was recorded for Artemisia spp. (41) and Berberis integerrima (40). The highest IAR Index was obtained for stings (0.86), followed by disorders in the circulatory system (0.7), dental problems (0.70) and injuries (0.69). Comparing our data with major ethnobotanical references in Iran revealed that medicinal applications of 34 taxa have not been cited, including Hyoscyamus malekianus, a local endemic plant using for ailments of toothache and worms. The toxicity of the endemic Semenovia suffruticosa is also reported. CONCLUSION: As a result of this study we conclude that Taftan area harbours many plant species for which indigenous knowledge provides a background of medicinal importance. The high percentage of medicinal plants proportional to the native flora is 23.8%, compared to the world percentage of 17.1%, is an indication of the rich knowledge and relationship of isolated Baluchi tribes living in Mt. Taftan to the local flora growing in their surroundings. This rich knowledge should be highly regarded as a cultural and ethnobotanical heritage. Furthermore, ethnobotanical results show some weak interrelation between Baluchi tribes living in Iran and Pakistan, probably because of a different flora and/or unfavourable environmental conditions and perhaps local conflicts which might have reduced active cultural exchange. PMID- 29447951 TI - Suction electrode recording in locus coeruleus of newborn rat brain slices reveals network bursting comprising summated non-synchronous spiking. AB - The brainstem locus coeruleus (LC) controling behaviors like arousal, sleep, breathing, pain or opioid withdrawal is an established model for spontaneous action potential synchronization. Such synchronous 'spiking' might produce an extracellular field potential (FP) which is a crucial tool for neural network analyses. We found using >=10 MUm tip diameter suction electrodes in newborn rat brainstem slices that the LC generates at ~1 Hz a robust rhythmic FP (rFP). During distinct rFP phases, LC neurons discharge with a jitter of +/-33 ms single spikes that summate to a ~200 ms-lasting population burst. The rFP is abolished by blocking voltage-gated Na+ channels with tetrodotoxin (TTX, 50 nM) or gap junctions with mefloquine (100 MUM) and activating MU-opioid receptors with [D Ala2,N-Me-Phe4,Gly5-ol]-Enkephalin (DAMGO, 1 MUM). Raising superfusate K+ from 3 to 7 mM either increases rFP rate or transforms its pattern to slower and longer multipeak bursts similar to those during early recovery from DAMGO. The results show that electrical coupling of neonatal LC neurons does not synchronize their spiking as previously proposed. They also indicate that both increased excitability (by elevated K+) and recovery from inhibition (by opioids) can enhance spike desynchronization to transform the population burst pattern. Both observations show that this gap junction-coupled neural network has a more complex connectivity than currently assumed. These new findings along with the inhibitory drug effects that are in line with previous reports based on single neuron recording point out that field potential analysis is pivotal to further the understanding of this brain circuit. PMID- 29447952 TI - Insulin enhances GABAA receptor-mediated inhibitory currents in rat central amygdala neurons. AB - Insulin, a pancreatic hormone, can access the central nervous system, activate insulin receptors distributed in selective brain regions and affect various cellular functions such as neurotransmission. We have previously shown that physiologically relevant concentration of insulin potentiates the GABAA receptor mediated tonic inhibition and reduces excitability of rat hippocampal CA1 neurons. The central nucleus of the amygdala (CeA) comprises heterogeneous neuronal populations that can respond to hormonal stimulus. Using quantitative PCR and immunofluorescent labeling, we report that the mRNA and protein of the insulin receptor are abundantly expressed in the rat CeA. The insulin receptor mRNA is also detected in the CeA from post-mortem human brain samples. Furthermore, our whole-cell patch-clamp recordings show that the application of insulin (5 and 50 nM) selectively enhances the frequency and amplitude of spontaneous inhibitory postsynaptic currents (sIPSCs) in rat CeA neurons. Our findings reveal that GABAergic synaptic transmission is a target in the CeA for insulin receptor signaling that may underlie insulin modulation of emotion- and feeding-related behaviors. PMID- 29447954 TI - The inhibitory effect of levo-tetrahydropalmatine on the methamphetamine-induced spatial memory impairment in mice. AB - Methamphetamine (METH) administration results in addiction and memory impairment. Previous studies have suggested that levo-tetrahydropalmatine (l-THP), an alkaloid purified from the Chinese herb Corydalis, attenuates the behavioral changes induced by METH. Therefore, in this study, we explored whether l-THP could also protect against the METH-induced memory impairment examined using the Morris water maze (MWM). We found that low dose of METH (1.0 mg/kg) treated for 20 consecutive days prior to the MWM experiment impaired spatial memory retention but not acquisition in mice. In addition, high dose of METH (10.0 mg/kg) treated during the spatial learning phase for five consecutive days impaired both the acquisition and retention of spatial memory. Moreover, both of these impairments induced by METH were reversed by l-THP treatment, indicating a potential protective role of l-THP in METH use. PMID- 29447953 TI - Dendrite growth and the effect of ectopic Rheb expression on cortical neurons. AB - Ras homology enriched in brain (Rheb) is a GTPase that activates the protein kinase mammalian Target of Rapamycin (mTOR). Rheb mutations cause intellectual delay and megalencephaly. mTOR hyperactivation causes a constellation of neurodevelopmental disorders called "mTOR-opathies" that are frequently accompanied by hyperexcitable cortical malformations. Cortical malformations within the anterior cingulate cortex (ACC) and somatosensory cortex (SSC) frequently colocalize with hyperexcitability. Although Rheb and mTOR are implicated in the formation of cortical lesions, seizure activity, and defects in neuronal migration, the contribution of Rheb to changes in neuron size and dendrite morphology is not well established. Here, in utero electroporation of the developing embryonic brain was used to assess soma and dendrite growth in ACC and SCC layer II/III neurons. We found that between P0 and P21, neuronal soma size increased by 50 and 122 percent in the ACC and SSC, respectively. The increased size was accompanied by an increase in the number of basal dendrites and enhanced dendrite complexity. As an indicator of the involvement of the mTOR pathway in neuron maturation, phosphorylation of the mammalian target of rapamycin (mTOR) substrate S6 was identified in migrating cortical neuroblasts and maturing neurons. Notably, ectopic expression of Rheb caused cortical malformations comprised of ectopically positioned cytomegalic neurons with dendrite hypertrophy. This study provides a direct comparison of neuron maturation across two cortical regions during development, provides evidence for mTOR pathway activity during neuron maturation, and demonstrates that ectopic Rheb expression without mutation is sufficient to induce cortical malformations with cytomegaly and dendrite hypertrophy. PMID- 29447955 TI - PTH (1-34) affects bone turnover governed by osteocytes exposed to fluoride. AB - Exposure to fluoride from environmental sources remains an overlooked, but serious public health risk. In this study, we looked into the role osteocytes play on the mechanism underlying fluoride induced osteopathology. We analyzed bone formation and resorption related genes generated by osteocytes that were exposed to varied doses of fluoride with and without PTH in vitro. Correspondingly, osteogenesis and osteoclastogenesis related genes were also investigated in rats exposed to fluoride for 8 weeks, and the PTH(1-34)was applied at the last 3 weeks to observe its role in regulating bone turnover upon fluoride treatment. The data in vitro indicated that fluoride treatment inhibited Sost expression of mRNA and protein and stimulated RANKL mRNA protein expression as well as the RANKL/OPG ratio in the primary osteocytes. Single PTH treatment played the similar role on expression of these genes and proteins. The PTH combined administration enhanced the action of fluoride treatment on RNAKL/OPG and SOST/Sclerostin. The up-regulation of RANKL and decreasing of Sost induced by fluoride and/or PTH treatment was validated in vivo and suggests that osteocytes are a major source of RANKL and Sost, both of which play essential roles in fluoride affecting osteogenesis and osteoclastogenesis. Expression of Wnt/beta catenin was up-regulated in both in vitro osteocytes treated with high dose of fluoride and bone tissue of rats in the presence of fluoride and PTH. In vivo, fluoride and single PTH stimulated bone turnover respectively, furthermore, PTH combined with low dose of fluoride treatment reinforced the osteogenesis and osteoclastogenesis genes expression, however, co-treatment of PTH reversed the effect of high dose of fluoride on osteogenesis and osteoclastogenensis related factors. In conclusion, this study demonstrated that osteocytes play a key role in fluoride activated bone turnover, and PTH participates in the process of fluoride modulating SOST/Sclerostin and RANKL expression. PMID- 29447956 TI - Pubertal chlorocholine chloride exposure inhibits testicular testosterone synthesis by down-regulating steroidogenic enzymes in adult rats. AB - Chlorocholine chloride (CCC) is widely used to regulate plant growth. Considerable attention has been focused on its reproductive and developmental toxicities. In order to investigate the effects of pubertal CCC exposure on testicular testosterone (T) synthesis, male SD rats were exposed to CCC by oral gavage at doses of 0, 75, 150 and 300 mg/kg bw/day from postnatal day 23 to 70. We observed that pubertal CCC exposure lowered the body weight and the mean Johnsen's score. The percentage of seminiferous tubules with deciduous spermatogenic cells was increased in the 75 and 150 mg/kg bw/day groups. In addition, pubertal CCC exposure reduced the testicular absolute weights in the 75 and 300 mg/kg bw/day groups as well as the sperm motility in epididymides in the 150 mg/kg bw/day group. A significant decrease of testicular T was observed while levels of hypothalamic gonadotropin-releasing-hormone (GnRH) and serum luteinizing hormone (LH) were increased. Protein levels of steroidogenic acute regulatory (StAR), cholesterol side-chain cleavage enzyme (P450scc) and 3beta hydroxysteroid dehydrogenase (3beta-HSD) were decreased. Taken together, these results indicate that pubertal CCC exposure in rats might decrease testicular T synthesis by suppressing the expression of steroidogenic enzymes, which partially lead to an impairment on spermatogenesis. PMID- 29447957 TI - The effects of lead exposure on the expression of HMGB1 and HO-1 in rats and PC12 cells. AB - Lead (Pb) is an environmental neurotoxic metal. Chronic exposure to Pb causes deficits of learning and memory in children and spatial learning deficits in developing rats. In this study we investigated the effects of Pb exposure on the expression of HMGB1 and HO-1 in rats and PC12 cells. The animals were randomly divided to three groups: control group; low lead exposure group; high lead exposure group; PC12 cells were divided into 3 groups: 0 MUM (control group), 1 MUM and 100 MUM Pb acetate. The results showed that Pb levels in blood and brain of Pb exposed groups were significantly higher than that of the control group (p < 0.05). The expression of HMGB1 and HO-1 were increased in Pb exposed groups than that of the control group (p < 0.05). Moreover, we found that the up regulation of HO-1 in Pb exposure environment inhibited the expression of HMGB1. PMID- 29447958 TI - Serelaxin as a novel therapeutic opposing fibrosis and contraction in lung diseases. AB - The most common therapies for asthma and other chronic lung diseases are anti inflammatory agents and bronchodilators. While these drugs oppose disease symptoms, they do not reverse established structural changes in the airways and their therapeutic efficacy is reduced with increasing disease severity. The peptide hormone, relaxin, is a Relaxin Family Peptide Receptor 1 (RXFP1) receptor agonist with unique combined effects in the lung that differentiates it from these existing therapies. Relaxin has previously been reported to have cardioprotective effects in acute heart failure as well anti-fibrotic actions in several organs. This review focuses on recent experimental evidence of the beneficial effects of chronic relaxin treatment in animal models of airways disease demonstrating inhibition of airway hyperresponsiveness and reversal of established fibrosis, consistent with potential therapeutic benefit. Of particular interest, accumulating evidence demonstrates that relaxin can also acutely oppose contraction by reducing the release of mast cell-derived bronchoconstrictors and by directly eliciting bronchodilation. When used in combination, chronic and acute treatment with relaxin has been shown to enhance responsiveness to both glucocorticoids and beta2-adrenoceptor agonists respectively. While the mechanisms underlying these beneficial actions remain to be fully elucidated, translation of these promising combined preclinical findings is critical in the development of relaxin as a novel alternative or adjunct therapeutic opposing multiple aspects of airway pathology in lung diseases. PMID- 29447959 TI - Effects of maturation and advanced glycation on tensile mechanics of collagen fibrils from rat tail and Achilles tendons. AB - : Connective tissues are ubiquitous throughout the body and consequently affect the function of many organs. In load bearing connective tissues like tendon, the mechanical functionality is provided almost exclusively by collagen fibrils that in turn are stabilized by covalent cross-links. Functionally distinct tendons display different cross-link patterns, which also change with maturation, but these differences have not been studied in detail at the fibril level. In the present study, a custom built nanomechanical test platform was designed and fabricated to measure tensile mechanics of individual fibrils from rat tendons. The influence of animal maturity (4 vs. 16 week old rats) and functionally different tendons (tail vs. Achilles tendons) were examined. Additionally the effect of methylglyoxal (MG) treatment in vitro to form advanced glycation end products (AGEs) was investigated. Age and tissue type had no significant effect on fibril mechanics, but MG treatment increased strength and stiffness without inducing brittleness and gave rise to a distinct three-phase mechanical response corroborating that previously reported in human patellar tendon fibrils. That age and tissue had little mechanical effect, tentatively suggest that variations in enzymatic cross-links may play a minor role after initial tissue formation. STATEMENT OF SIGNIFICANCE: Tendons are connective tissues that connect muscle to bone and carry some of the greatest mechanical loads in the body, which makes them common sites of injury. A tendon is essentially a biological rope formed by thin strands called fibrils made of the protein collagen. Tendon function relies on the strength of these fibrils, which in turn depends on naturally occurring cross-links between collagen molecules, but the mechanical influence of these cross-links have not been measured before. It is believed that beneficial cross linking occurs with maturation while additional cross-linking with aging may lead to brittleness, but this study provides evidence that maturation has little effect on mechanical function and that age-related cross-linking does not result in brittle collagen fibrils. PMID- 29447960 TI - Mechanically enhanced nested-network hydrogels as a coating material for biomedical devices. AB - : Well-organized composite formations such as hierarchical nested-network (NN) structure in bone tissue and reticular connective tissue present remarkable mechanical strength and play a crucial role in achieving physical and biological functions for living organisms. Inspired by these delicate microstructures in nature, an analogous scaffold of double network hydrogel was fabricated by creating a poly(2-hydroxyethyl methacrylate) (pHEMA) network in the porous structure of alginate hydrogels. The resulting hydrogel possessed hierarchical NN structure and showed significantly improved mechanical strength but still maintained high elasticity comparable to soft tissues due to a mutual strengthening effect between the two networks. The tough hydrogel is also self lubricated, exhibiting a surface friction coefficient comparable with polydimethylsiloxane (PDMS) substrates lubricated by a commercial aqueous lubricant (K-Y Jelly) and other low surface friction hydrogels. Additional properties of this hydrogel include high hydrophilicity, good biocompatibility, tunable cell adhesion and bacterial resistance after incorporation of silver nanoparticles. Firm bonding of the hydrogel on silicone substrates could be achieved through facile chemical modification, thus enabling the use of this hydrogel as a versatile coating material for biomedical applications. STATEMENT OF SIGNIFICANCE: In this study, we developed a tough hydrogel by crosslinking HEMA monomers in alginate hydrogels and forming a well-organized structure of hierarchical nested network (NN). Different from most reported stretchable alginate-based hydrogels, the NN hydrogel shows higher compressive strength but retains comparable softness to alginate counterparts. This work further demonstrated the good integration of the tough hydrogel with silicone substrates through chemical modification and micropillar structures. Other properties including surface friction, biocompatibility and bacterial resistance were investigated and the hydrogel shows a great promise as a versatile coating material for biomedical applications. PMID- 29447961 TI - A physiologically relevant 3D collagen-based scaffold-neuroblastoma cell system exhibits chemosensitivity similar to orthotopic xenograft models. AB - : 3D scaffold-based in vitro cell culturing is a recent technological advancement in cancer research bridging the gap between conventional 2D culture and in vivo tumours. The main challenge in treating neuroblastoma, a paediatric cancer of the sympathetic nervous system, is to combat tumour metastasis and resistance to multiple chemotherapeutic drugs. The aim of this study was to establish a physiologically relevant 3D neuroblastoma tissue-engineered system and explore its therapeutic relevance. Two neuroblastoma cell lines, chemotherapeutic sensitive Kelly and chemotherapeutic resistant KellyCis83 were cultured in a 3D in vitro model on two collagen-based scaffolds containing either glycosaminoglycan (Coll-GAG) or nanohydroxyapatite (Coll-nHA) and compared to 2D cell culture and an orthotopic murine model. Both neuroblastoma cell lines actively infiltrated the scaffolds and proliferated displaying >100-fold increased resistance to cisplatin treatment when compared to 2D cultures, exhibiting chemosensitivity similar to orthotopic xenograft in vivo models. This model demonstrated its applicability to validate miRNA-based gene delivery. The efficacy of liposomes bearing miRNA mimics uptake and gene knockdown was similar in both 2D and 3D in vitro culturing models highlighting the proof-of-principle for the applicability of 3D collagen-based scaffolds cell system for validation of miRNA function. Collectively, this data shows the successful development and characterisation of a physiologically relevant, scaffold-based 3D tissue engineered neuroblastoma cell model, strongly supporting its value in the evaluation of chemotherapeutics, targeted therapies and investigation of neuroblastoma pathogenesis. While neuroblastoma is the specific disease being focused upon, the platform may have multi-functionality beyond this tumour type. STATEMENT OF SIGNIFICANCE: Traditional 2D cell cultures do not completely capture the 3D architecture of cells and extracellular matrix contributing to a gap in our understanding of mammalian biology at the tissue level and may explain some of the discrepancies between in vitro and in vivo results. Here, we demonstrated the successful development and characterisation of a physiologically relevant, scaffold-based 3D tissue-engineered neuroblastoma cell model, strongly supporting its value in the evaluation of chemotherapeutics, targeted therapies and investigation of neuroblastoma pathogenesis. The ability to test drugs in this reproducible and controllable tissue-engineered model system will help reduce the attrition rate of the drug development process and lead to more effective and tailored therapies. Importantly, such 3D cell models help to reduce and replace animals for pre-clinical research addressing the principles of the 3Rs. PMID- 29447962 TI - Low molecular weight fucoidan attenuates liver injury via SIRT1/AMPK/PGC1alpha axis in db/db mice. AB - Non-alcoholic fatty-liver disease (NAFLD), caused by elevated hepatic lipids, inflammation and oxidative stress, is the most common liver disease globally. Low molecular weight fucoidan (LMWF), a sulfated polysaccharide extracted from brown seaweeds, has shown strong anti-inflammatory and antioxidant activities, which has not been explored in diabetes-induced NAFLD. Therefore, the present study sought to determine whether LMWF protects obese diabetic db/db mice against NAFLD. Results showed LMWF administration decreased plasma level of alanine aminotransferase, aspartate aminotransferase, total cholesterol, and triglyceride, as well as alleviated hepatic accumulation of triglyceride and total cholesterol in db/db mice. LMWF also ameliorated hepatic oxidative stress by suppressing superoxide production and lipid peroxidation, and increasing catalase and superoxide dismutase activity in the liver of db/db mice. Furthermore, LMWF down-regulated several pro-inflammatory cytokines and transcription factor, and up-regulated the anti-inflammatory adiponectin. These changes were accompanied by the activation of hepatic SIRT1/AMPK/PGC1alpha signaling with LMWF treatment. In addition, blocking SIRT1 or AMPK by inhibitor notably abolished LMWF-elicited protection against palmitic acid-induced oxidative stress and inflammation in hepatocytes. These results suggest LMWF prevents NAFLD in db/db mice by activation of SIRT1/AMPK/PGC1alpha signaling pathway, which prevents lipotoxicity-related oxidative stress and inflammation. Therefore, LMWF provides a potential supplementary treatment for obesity/diabetes induced NAFLD.

AB - Anthocyanin derivatives are well-known secondary constituents contained in fruits. The inhibitory activity of anthocyanin derivatives toward soluble epoxide hydrolase (sEH) was tested for potential applications in the treatment of cardiovascular diseases. Anthocyanin derivatives 1-5 showed dose-dependent inhibitory activity toward sEH, with IC50 values ranging from 4.3+/-0.2 to 25.3+/ 2.6MUM. Lineweaver-Burk plots showed that all anthocyanin derivatives preferentially interacted with allosteric sites instead of active sites as noncompetitive (1-3) and mixed (4 and 5) inhibitors. Furthermore, the cavity located next to the active site may interact with anthocyanin derivatives (1-5) by molecular docking. Among the tested derivatives, (4) bonded with key amino acids at two loops around the binding site for 10ns. Finally, anthocyanin derivatives (1-5) are potential inhibitors of sEH, and anthocyanin-rich fruits may be useful for the targeted treatment of cardiovascular diseases via sEH inhibition.

AB - Congenital muscular torticollis (CMT) is a neck deformity that involves shortening of sternocleidomastoid muscle (SCM) characterized by muscle atrophy and interstitial fibrosis. To investigate wheatear Botulinum toxin type A (BTA) has anti-fibrotic effects in CMT, we established acquired muscular torticollis that mimetics CMT in rabbit by intra-SCM injection of anhydrous alcohol. The treatment groups received BTA (2.5units or 5units) injection into the fibrotic SCM. The shortening and thickening of SCM were recorded by B-mode ultrasound. Changes in Col1A1, Fn, alpha-SMA expression were determined by immunohistochemistry. In vitro studies, TGF-beta induced NIH3T3 fibroblasts were used to evaluate anti-fibrosis effect of BTA. Expression of the myofibroblast marker alpha-SMA and fibrosis markers Col1A1 and Fn were detected by Western blotting and quantitative RT-PCR. Our results showed that BTA injection attenuated shortening and thickening of fibrotic SCM. Elevated expression of Col1A1, Fn, alpha-SMA were confirmed in this fibrotic muscle model but reversed after BTA injection. Similar results observed in TGF-beta induced NIH3T3 fibroblasts in both mRNA and protein levels. In conclusion, our results suggested that BTA could be a promising agent against SCM fibrosis in CMT through regulating fibroblast and inhibiting myofibroblast differentiation.

AB - A facile method for the fabrication of crosslinked chitosan/graphene nanoplates composite sphere (CS/GNPs) was presented. The obtained samples were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopic (XPS) and thermogravimetric analysis (TGA). The adsorption activities of CS/GNPs for methyl orange (MO) and acid red 1 (AR1) were evaluated such as the effect of pH and GNPs content, as well as adsorption kinetics and isotherms. In view of practical, the reusability of CS/GNPs was also tested. The resulting adsorption capacity for MO is 230.91mgg-1 and 132.94mgg-1 for AR1, respectively. After saturated adsorption, CS/GNPs can be efficiently regenerated and reused with little uptake loss. Therefore, CS/GNPs is the apromising adsorbent with non-toxic, efficient, low-cost and easy to prepare for the dye removal.

Although a gluten free diet usually induces clinical improvements within days or weeks, adhering to this routine is still troublesome. Therefore, new solutions are needed for quality-of-life improvement of CD patients. The present work intends to bring molecular and thermodynamic insights on the ability of green tea epigalhocatechin 3-gallate (EGCG) to interact and modulate the bioavailability of a major CD immunodominant peptide (32-mer). Characterization of peptide binding was assessed by means of both 1D and 2D 1H NMR experiments, ITC and Molecular Dynamics simulations. Accordingly, EGCG not only exhibits a high reactivity towards the 32 mer peptide as its binding appears to be entropy-driven and involves two sequential binding events, each with different binding strengths. Structural rearrangements were also detected during the interaction, contributing to a greater stability of the formed complexes. In vitro transepithelial transport assays using a Caco-2 cell line model were also performed and highlighted the ability of EGCG to significantly reduce the concentration of free peptide in the basolateral compartment. Overall, this study provides important evidences regarding the structural features and molecular mechanisms by which EGCG could interact and potentially modulate the function of some bioactive CD peptides. PMID- 29447967 TI - Fabrication and characterization of chitosan conjugated eurycomanone nanoparticles: In vivo evaluation of the biodistribution and toxicity in fish. AB - Chitosan nanoparticles (CNPs) have been proven considerable delivery agents due to their remarkable physicochemical properties. Present study reports the fabrication of CNPs by ionic gelation process and their characterization by different approaches. The constructed nanoparticles were successfully conjugated with eurycomanone with significant entrapment efficiency. Particle size of chitosan and chitosan conjugated eurycomanone nanoparticles were 126.2nm and 130nm respectively. Scanning electron microscopy showed that the particles were spherical in shape and well dispersed. Cross-linking between CNPs and eurycomanone (CENPs) were confirmed by Fourier-transform infrared (FTIR) spectroscopy. Fluorescent nanoparticles were prepared by using Rhodamine-6G dye, characterised by SEM and confirmed for conjugation by FTIR. Biodistribution of CENPs showed the presence of fluorescent nanoparticles in liver, kidney, testes and brain of C. magur. The toxicity of CENPs was evaluated by comparing the histological sections of catfish testes collected from treated and control group. No signs of toxicity were seen in testes after the delivery of CENPs. Molecular docking study revealed high spontaneous binding ability of chitosan with eurycomanone and aromatase enzyme. The study reports that CNPs can act as a stabilizing agent for eurycomanone formulation and could be a promising approach to increase the reproductive performance of the fishes. PMID- 29447968 TI - Impact of acidic, water and alkaline extraction on structural features, antioxidant activities of Laminaria japonica polysaccharides. AB - This study comparatively evaluated the effects of different extraction methods on yield, structural features and antioxidant activities of Laminaria japonica (L. japonica) polysaccharides. Results showed that acid, water and alkaline extracted L. japonica polysaccharides (LJP-CA, LJP-W and LJP-A, respectively) differed significantly. Among three polysaccharides, LJP-W showed the highest viscosity with high uronic acid content and average molecular weight, whereas LJP-CA showed the lowest viscosity with low uronic acid and high sulfate content with moderate average molecular weight. LJP-CA was mainly composed of fucose, mannose and galactose, but the proportion of glucose was greatly increased in LJP-W and LJP A. LJP-W had an even and smooth sheet-like appearance, while LJP-CA and LJP-A exhibited irregular and rough fragments or particles with stronger antioxidant activities. These results suggest that acid and alkali would propose an improved process for polysaccharide preparation from L. japonica and to exploit its potential application as a functional ingredient in food application. PMID- 29447969 TI - Novel piperonal 1,3,4-thiadiazolium-2-phenylamines mesoionic derivatives: Synthesis, tyrosinase inhibition evaluation and HSA binding study. AB - A novel series of piperonal mesoionic derivatives (PMI 1-6) was synthesized. Tyrosinase inhibition in the presence of PMI-1, -2, -3, -4, -5 and -6 as well as human serum albumin (HSA) binding studies with PMI-5 and PMI-6 were done by spectroscopic and theoretical methods. The mesoionic compound PMI-5 is the most promising tyrosinase inhibitor with a noncompetitive inhibitory mechanism and an IC50=124MUmolL-1. In accordance with the kinetic profile, molecular docking results show that PMI-5 is able to interact favorably with the tyrosinase active site containing the substrate molecule, L-DOPA, interacting with Val-247, Phe-263 and Val-282 residues. The spectroscopic results for the interaction HSA:PMI-5 and HSA:PMI-6 indicated that these mesoionic compounds can associate with HSA in the ground state and energy transfer can occur with high probability. The binding was moderate, spontaneous and can perturb significantly the secondary structure of the albumin. The molecular docking results suggest that PMI-5 and PMI-6 are able to be accommodated inside the Sudlow's site I in HSA, interacting with hydrophobic and hydrophilic amino acid residues. PMID- 29447970 TI - Development of a new paper based nano-biosensor using the co-catalytic effect of tyrosinase from banana peel tissue (Musa Cavendish) and functionalized silica nanoparticles for voltammetric determination of l-tyrosine. AB - In this paper, a new and facile method for the electrochemical determination of l tyrosine was designed. First, 3-mercaptopropyl trimethoxysilane-functionalized silica nanoparticles were added to a paper disc. Then, the banana peel tissue and the mediator potassium hexacyanoferrate were dropped onto the paper, respectively. The modified paper disc was placed on the top of the graphite screen printed electrode and electrochemical characterization of this biosensor was studied by cyclic voltammetry and electrochemical impedance spectroscopy methods. The effective parameters like pH, banana peel tissue percentage, and the amount of mediator loading were optimized. l-tyrosine measurements were done by differential pulse voltammetry with a little sample (3 MUL) for analysis. The biosensor showed a linear response for l-tyrosine in the wide concentration range of 0.05-600 MUM and a low detection limit about 0.02 MUM because of the co catalytic effect of enzyme and nanoparticles. The stability of the biosensor and its selectivity were evaluated. This biosensor was applied for the voltammetric determination of l-tyrosine in the blood plasma sample. The results of the practical application study were comparable with the standard method (HPLC). In conclusion, a simple, inexpensive, rapid, sensitive and selective technique was successfully applied to the l-tyrosine analysis of the little samples. PMID- 29447971 TI - Horseradish peroxidase immobilization by copolymerization into cross-linked polyacrylamide gel and its dye degradation and detoxification potential. AB - Owing to the ever-increasing environmental and health impacts associated with the discharge of dye-based effluents, effective remediation of industrial waste have become a top priority for the industrialists and environmental fraternity, around the world. Plant-based peroxidases represent a suitable bio-remediating agent for the effective treatment of original dyes or dye-based colored wastewater effluents. In the present study, horseradish peroxidase was immobilized by copolymerization into cross-linked polyacrylamide gel and investigated its potential for the degradation and detoxification of an azo dye, methyl orange. In the presence of N, N'-methylenebisacrylamide as a cross-linker, polyacrylamide gel at 10% concentration furnished >80% of immobilization yield. The surface morphology of the control (free enzyme) and immobilized enzyme, i.e., horseradish peroxidase cross-linked polyacrylamide gel was characterized using scanning electron microscopy. The high yielded horseradish peroxidase cross-linked polyacrylamide gel concentration, i.e., 10% was used to develop a packed bed reactor and exploited for dye degradation and detoxification purposes. A noteworthy level (>90%) of dye degradation was recorded after polyacrylamide gel cross-linked horseradish peroxidase-catalyzed reaction in a packed bed bioreactor. The biodegradation was further assessed by Fourier-transform infrared spectral analysis. The acute toxicity assays demonstrated that enzyme-based bio degradation might be used effectively for large-scale environmental remediation of dyes and dyes containing wastewater effluents. PMID- 29447972 TI - Novel asymmetric chitosan/PVP/nanocellulose wound dressing: In vitro and in vivo evaluation. AB - The present study was to develop a novel chitosan based symmetric and asymmetric bionanocomposite for potential wound dressing application. Chitosan (C)/Poly (vinyl pyrrolidone) (P)/nanocellulose (NC) membrane were fabricated by salt leaching method with the addition of 3% and 5% wt of nanocellulose. To obtain asymmetric material one side of the membrane was coated by stearic acid (S) which could form hydrophobic surface and another side acts as a hydrophilic surface. Nanocellulose of size 2-10nm was synthesized and characterized by TEM analysis. SEM showed the hydrophilic surface of asymmetric bionanocomposite consists of porous structure and hydrophobic surface is smooth and homogeneous. The results revealed that the Chitosan/PVP/Nanocellulose 3%-Stearic acid (CPNC3%-S) had a moderate swelling ratio, porosity, barrier and mechanical properties. Incorporation of nanocellulose into chitosan/PVP matrix could enhance the antibacterial activity. The hydrophobic surface of the CPNC3%-S bionanocomposite shows water repellent and antiadhesion properties towards E. coli bacteria and also the hydrophilic surface exhibit excellent antibacterial property and cytotoxicity towards bacterial pathogens. In vivo wound healing test shows better re-epithelialization and wound contraction compared with control and Chitosan/PVP stearic acid (CP-S) bionanocomposite. Asymmetric bionanocomposite Chitosan/PVP/Nanocellulose coated with 3%-Stearic acid (CPNC3%-S) exhibited very good invitro cytocompatibility and enabled a faster wound healing than symmetric dressing, hence showing great potential to be applied as wound dressings. PMID- 29447973 TI - Extraction, purification and antioxidation of a polysaccharide from Fritillaria unibracteata var. wabuensis. AB - Rich polysaccharides were directly observed in the bulbs of Fritillaria unibracteata var. wabuensis (FUW) using the periodic acid-Schiff (PAS) method and microexamination. An acidic water-soluble heteropolysaccharide (FWPS1-1) was isolated from FUW through ethanol precipitation, decoloration, deproteinization, dialysis and separation using a DE-52 anion-exchange column and a Sepharose G-150 gel filtration column. FWPS1-1 (average molecular weight: ~7.44 kDa) has many branches and long side chains; holds the triple-helix conformation; was composed of mannose (Man), galacturonic acid (GalA), galactose (Gal), xylose (Xyl) and arabinose (Ara) with a molar ratio of 2.62:5.59:10.00:0.76:9.38; and features side chains that may be composed of Ara, Man, Gal and GalA, while the backbone may be composed of Xyl, Ara and Gal. In addition, the backbone of FWPS1-1 mainly consists of alpha-type glycosidic bonds. Bioactivity tests in vitro showed that the polysaccharide exhibited weak 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity and low ferric reducing antioxidant power (FRAP) but high 2,2 azino-bis(3-ethylbenzthiazoline-6-sulfonic acid)l (ABTS) radical scavenging activity, good Fe(II)-chelating ability and remarkable DNA damage protective activity. FWPS1-1 was the first heteropolysaccharide purified from FUW and showed good antioxidant activity and DNA protective effect. The results confirmed that macromolecule is also bioactive ingredient that requires attention like the small molecule active compounds in FUW.

PMID- 29447975 TI - Profiling of novel microRNAs elicited by EV71 and CA16 infection in human bronchial epithelial cells using high-throughput sequencing. AB - Enterovirus 71 (EV71) and coxsackievirus A16 (CA16) are two major etiologic agents associated with hand, foot, and mouth disease (HFMD) worldwide. Despite that they both belong to the Enterovirus genus of the Picornaviridae family, there are many differences in the infection process of these viruses. However, the underlying mechanisms have not been elucidated. Multiple studies indicated that microRNAs (miRNAs) can play critical roles in the host-pathogen interaction. Our previous study reported that EV71 and CA16 infection leads to differential expression of miRNAs in human bronchial epithelial (16HBE) cells. Herein, we aimed to further explore the expression profile and possible roles of other differentially expressed miRNAs in 16HBE cells following EV71 and CA16 infections using high-throughput sequencing. We describe 44 novel differentially expressed miRNAs in all samples. Among these miRNAs, 7 novel differentially expressed miRNAs show an opposite expression trend during the progression of EV71 and CA16 infections. Subsequently, bioinformatics analyses, including Gene Oncology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) databases, were used to identify the biological processes, molecular functions, cellular components, and pathways involved. The top 10 significant GO and Pathway annotations indicated that 849 target genes are involved in cell development, such as nervous system development, multicellular organism development, and developmental biology. Finally, the genes identified in both the GO and Pathway analysis were used to construct a co-expression network to further identify the potential function of these co-expressed genes. Thus, our data may be beneficial in guiding further studies on the molecular mechanism of developmental regulation in HFMD pathogenesis caused by EV71 and CA16. In addition, it provided new candidate biomarkers or therapeutic targets for HFMD. PMID- 29447976 TI - Identification of a novel host protein SINAL10 interacting with GP64 and its role in Bombyx mori nucleopolyhedrovirus infection. AB - Bombyx mori nucleopolyhedrovirus (BmNPV) is the most important pathogen of Bombyx mori, silkworm and causes severe losses in the silk industry. During the virus infectious cycle, budded virus (BVs) and occlusion-derived virus (ODVs) particles, which have identical genetic content but different phenotypes, are produced. The envelope glycoprotein GP64, specific in BVs, is involved in host cell receptor binding and is sufficient to mediate membrane fusion during the viral entry. However, the host cell factors, interacting with GP64 to mediate BVs infection, are still unknown. In this study, a cDNA library of Bombyx mori cells (BmN) was constructed and yeast two-hybrid screening was used to identify the host cell factors interacting with GP64. One of the eight candidate proteins encoded the E3 ubiquitin-protein ligase SINA-like 10 (SINAL10), was further confirmed through coimmunoprecipitation assays as novel GP64 binding protein. Moreover, overexpression of SINAL10 significantly enhances viral reproduction, and conversely, silencing its expression by small interfering RNAs showed significant inhibitory effects. Collectively, we demonstrated that SINAL10 is a novel GP64-binding protein that stimulates BmNPV proliferation. PMID- 29447977 TI - Serratene-type triterpenoids from Palhinhaea cernua. AB - Phytochemical investigation of the 95% ethanol extract of the whole plant of Palhinhaea cernua afforded five new serratene-type triterpenoids (1-5) together with four known analogues (6-9). The structures of the new compounds were elucidated by extensive spectroscopic analysis and X-ray crystallographic data. Compounds 1-3 triggered apoptosis of Hela-/- cell with EC50 values of 3.49 +/- 0.05, 0.28 +/- 0.13 and 7.98 +/- 0.03 MUM, respectively. PMID- 29447978 TI - The influence of procyanidins isolated from small-leaved lime flowers (Tilia cordata Mill.) on human neutrophils. AB - Linden flower is a wildly used plant material among patients in the treatment of common cold symptoms and mucosa inflammations. However, the structure and bioactivity of flavan-3-ol derivatives present in infusions from flowers of Tilia cordata have not been studied so far. The aim of current study was to isolate and identify main procyanidins present in the flowers of small-leaved lime and to evaluate their influence on the inflammatory response of human neutrophils ex vivo. The chemical structure of isolated compounds was established by 1D and 2D NMR experiments. The bioactivity of obtained compounds was tested in human neutrophils model. Cytotoxicity and influence of compounds on apoptosis was established by flow cytometry. The levels of produced cytokines were established by ELISA after stimulation with lipopolysaccharide (LPS). The inhibition of the production of reactive oxygen species was checked by luminol-dependent chemiluminescence method after N-formylmethionyl-leucyl-phenylalanine (f-MLP) induction. The phytochemical work resulted in the isolation of 10 compounds. Compounds were identified as oligomeric procyanidins and their precursor epicatechin. The potential anti-inflammatory activity of compounds was evaluated in the concentration range 5-20 MUM. All compounds were able to decrease the production of ROS from f-MLP-stimulated neutrophils. Most of compounds were able to inhibit the LPS-induced release of IL-8. Some trimeric and tetrameric derivatives were also able to decrease the production of MIP-1beta. Obtained results partially support the traditional usage of infusion from lime flowers in the treatment of symptoms of inflammation and irritation of mucosa in common cold, pharyngitis and tonsillitis. PMID- 29447979 TI - Jatrophanes as promising multidrug resistance modulators: Advances of structure activity relationships. AB - The phytochemical study of Euphorbia helioscopia afforded euphornin (1) in a large amount. Alkaline hydrolysis of 1 using potassium carbonate yielded the main product monodeacetyleuphornin (2), whose structural modification at 14-OH gave rise to 21 acylated derivatives euphornoate A-U (3-23). Thus, a mini compound library of jatrophanes was established to screen for MDR modulators. Biological studies clearly demonstrated the effect of C-14 pattern modification in MDR reversal activity and several compounds with RF values over 300 fold at 20 MUM (6, 16, 20, 22, 23) were thought to be promising MDR modulators. The SARs are discussed, which reveal that introduction of an alkyl acyl group bearing 4 carbons at C-14 or an aryl acyl group with electron donating groups is favorable for the activity. PMID- 29447980 TI - Megastigmane glycosides from Urena lobata. AB - Five new megastigmane glycosides, urenalobasides A-E (1-5), together with 11 known ones (6-16) were isolated from Urena lobata. Their structures were determined by extensive spectroscopic and spectrometric data (1D and 2D NMR, IR, and HRESIMS) and calculated electronic circular dichroism method. Compounds 1 and 2 are two unusual megastigmanes structurally containing a 6/5 fused ring system. Compound 3 exhibits inhibition of nitric oxide production in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophage cells with IC50 value of 53.7 +/- 1.0 MUM (positive control, dexamethasone, IC50 = 16.6 +/- 0.8 MUM). PMID- 29447981 TI - Evaluation of in vitro/in vivo anti-diabetic effects and identification of compounds from Physalis alkekengi. AB - The aims of the present study were to assess the anti-diabetic effects of Physalis alkekengi L. (PA) in 3T3-L1 pre-adipocyte cells and HepG2-GFP-CYP2E1 (E47) cells and in a pre-diabetic rat model, as well as to identify the active chemical constituents. The in vitro results showed that PA has a strong anti diabetic capacity to relieve oxidative stress and inhibit alpha-glucosidase activity. Mechanistic analysis also showed that ethyl acetate extracts of aerial parts and fruit of PA (PAG-EA and PAF-EA) enhanced glucose transporter 4 expression and function as well as enhanced insulin sensitivity by inhibiting the expression of cytochrome P450-2E1 (CYP2E1) mRNA and protein. In vivo, PAG-EA and PAF-EA significantly decreased the levels of fasting blood glucose and fasting insulin, as well as total cholesterol and triglyceride, in the pre-diabetic rats. The results from insulin sensitivity index and homeostasis model assessment insulin resistance index along with an oral glucose tolerance test also showed that PAG-EA and PAF-EA could significantly enhance the insulin sensitivity, which confirmed the in vitro findings. Moreover, HPLC-ESI-QTOF-MS analysis identified flavonoids, physalins and phenolic acids as the main plant constituents. Our findings support the ethnopharmacological use of PA fruit, along with its aerial parts, as a strong anti-diabetic agent. The EA fraction, especially the constituent polyphenols and flavonoids, may have a good potential to treat diabetes.

AB - Three new diterpenoids, spiroscutelones A-C (1-3), along with known diterpene 4, were isolated from the leaves of Plectranthus scutellarioides. Their structures were established based on extensive spectroscopic analyses, including MS and NMR spectroscopy. Spiroscutelone A (1) represents the first example of an abietane type terpenoid skeleton with a cyclobutane moiety linking the B and C rings. Of compounds 1-4, spiroscutelone B (2) exhibited the most potent cytotoxicities against the three tested human cancer lines [breast (MCF-7), pancreatic (PSN-1), and cervical (HeLa)] with IC50 values ranging from 17.9 MUM to 29.8 MUM and low cytotoxicity against a lung fibroblast (WI-38) normal cell line.

AB - Willow (Salix sp.) is a historically well-known herbal medicine that provided the lead compound (salicin) for the discovery of aspirin, one of the most successful plant derived drugs in human medicine. During a metabolomics screen of 86 Salix species contained in the UK National Willow Collection, we have discovered, isolated and fully characterised a new natural salicinoid - salicin-7-sulfate.

PMID- 29447985 TI - Selected terpenes from leaves of Ocimum basilicum L. induce hemoglobin accumulation in human K562 cells. AB - Re-expression of fetal hemoglobin (HbF) was proposed as a possible therapeutic strategy for beta-haemoglobinopathies. Although several inducers of HbF were tested in clinical trials, only hydroxyurea (HU) received FDA approval. Despite it produced adequate HbF levels only in half of HU-treated SCD patients, and was ineffective at all in beta-thalassemia patients, beneficial effects of this approach suggested to continue in this direction identifying further molecules capable of inducing HbF. We tested the potential of essential oil isolated from Ocimum basilicum L. leaves (ObEO) in inducing hemoglobin biosynthesis. Initially, dose-dependent effect and kinetics of hemoglobin accumulation in K562 cells after treatment with ObEO were evaluated. ObEO induced dose-dependent hemoglobin accumulation superior to hydroxyurea and rapamycin and a strongest gamma-globin mRNA expression. Terpenes composition of ObEO was studied by GC-MS. Three main constituents, linalool, eugenol and eucalyptol, represented about 75% of total. A blend of these three terpenes fully replicated the ObEO's biological effect, thus indicating that one of them or all together could be the active ingredients. When terpenes were tested individually, eugenol was the only one inducing stable hemoglobin accumulation, while eucalyptol and linalool produced only a small transient response. However, eugenol potential was strongly enhanced in the presence of eucalyptol and linalool, suggesting a synergistic effect on hemoglobin accumulation. By these results, the discovery of a new inducer and the interesting activity of a blend of major terpenes from ObOE on Hb accumulation could have positive fallouts on beta-thalassemia and sickle cells anemia.

AB - BACKGROUND: The present review is part of the ESCMID Study Group for Infections in Compromised Hosts (ESGICH) Consensus Document on the safety of targeted and biological therapies. AIMS: To review, from an Infectious Diseases perspective, the safety profile of agents targeting interleukins, immunoglobulins and complement factors and to suggest preventive recommendations. SOURCES: Computer based MEDLINE searches with MeSH terms pertaining to each agent or therapeutic family. CONTENT: Patients receiving interleukin-1 (IL-1) -targeted (anakinra, canakinumab or rilonacept) or IL-5-targeted (mepolizumab) agents have a moderate risk of infection and no specific prevention strategies are recommended. The use of IL-6/IL-6 receptor-targeted agents (tocilizumab and siltuximab) is associated with a risk increase similar to that observed with anti-tumour necrosis factor alpha agents. IL-12/23-targeted agents (ustekinumab) do not seem to pose a meaningful risk of infection, although screening for latent tuberculosis infection may be considered and antiviral prophylaxis should be given to hepatitis B surface antigen-positive patients. Therapy with IL-17-targeted agents (secukinumab, brodalumab and ixekizumab) may result in the development of mild-to moderate mucocutaneous candidiasis. Pre-treatment screening for Strongyloides stercoralis and other geohelminths should be considered in patients who come from areas where these are endemic who are receiving IgE-targeted agents (omalizumab). C5-targeted agents (eculizumab) are associated with a markedly increased risk of infection due to encapsulated bacteria, particularly Neisseria spp. Meningococcal vaccination and chemoprophylaxis must be administered 2-4 weeks before initiating eculizumab. Patients with high-risk behaviours and their partners should also be screened for gonococcal infection. IMPLICATIONS: Preventive strategies are particularly encouraged to minimize the occurrence of neisserial infection associated with eculizumab. PMID- 29447989 TI - Aetiology of lower respiratory tract infection in adults in primary care: a prospective study in 11 European countries. AB - OBJECTIVES: To describe the role of bacteria (including bacterial resistance), viruses (including those recently described) and mixed bacterial-viral infections in adults presenting to primary care with lower respiratory tract infection (LRTI). METHODS: In all, 3104 adults with LRTI were enrolled, of whom 141 (4.5%) had community-acquired pneumonia (CAP), and 2985 matched controls in a prospective study in 16 primary care networks in Europe, and followed patients up at 28-35 days. We detected Streptococcus pneumoniae and Haemophilus influenzae and assessed susceptibility, atypical bacteria and viruses. RESULTS: A potential pathogen was detected in 1844 (59%) (in 350 (11%) bacterial pathogens only, in 1190 (38%) viral pathogens only, and in 304 (10%) both bacterial and viral pathogens). The most common bacterial pathogens isolated were S. pneumoniae (5.5% overall, 9.2% in CAP patients) and H. influenzae (5.4% overall, 14.2% in CAP patients). Less than 1% of S. pneumoniae were highly resistant to penicillin and 12.6% of H. influenzae were beta-lactamase positive. The most common viral pathogens detected were human rhinovirus (20.1%), influenza viruses (9.9%), and human coronavirus (7.4%). Influenza virus, human parainfluenza viruses and human respiratory syncytial virus as well as human rhinovirus, human coronavirus and human metapneumovirus were detected significantly more frequently in LRTI patients than in controls. CONCLUSIONS: A bacterial pathogen is identified in approximately one in five adult patients with LRTI in primary care, and a viral pathogen in just under half, with mixed infections in one in ten. Penicillin resistant pneumococci and beta-lactamase-producing H. influenzae are uncommon. These new findings support a restrictive approach to antibiotic prescribing for LRTI and the use of first-line, narrow-spectrum agents in primary care.

AIMS: To review, from an Infectious Diseases perspective, the safety profile of agents targeting CD19, CD20 and CD52 and to suggest preventive recommendations. SOURCES: Computer-based MEDLINE searches with MeSH terms pertaining to each agent or therapeutic family. CONTENT: Although CD19 targeted agents (blinatumomab or inebilizumab) are not associated with an increased risk of infection, they may cause IgG hypogammaglobulinaemia and neutropenia. The requirement for prolonged intravenous infusion of blinatumomab may increase the risk of catheter-associated bloodstream infections. Infection remains the most common non-haematological adverse effect of anti-CD20 monoclonal antibodies, including severe respiratory tract infection, hepatitis B virus (HBV) reactivation and varicella-zoster virus infection. Screening for chronic or resolved HBV infection is recommended for patients receiving anti-CD20 monoclonal antibodies. Antiviral prophylaxis should be offered for 12-18 months to hepatitis B surface antigen (HBsAg)-positive and HBsAg-negative/anti-hepatitis B core antibody (HBc)-positive patients. Anti-Pneumocystis prophylaxis should be considered in patients receiving concomitant chemotherapy, particularly steroids. Alemtuzumab (anti-CD52) increases the risk of infections, in particular among leukaemia and solid organ transplant patients. These populations benefit from anti-Pneumocystis prophylaxis, prevention strategies for cytomegalovirus infection, and screening for HBV, hepatitis C virus and tuberculosis. Antiviral prophylaxis for at least 6-12 months should be provided for HBsAg-positive patients. IMPLICATIONS: As there are limited clinical data for many of the reviewed agents, special attention must be given to promptly detect and report emerging infectious complications.

Household members and work styles influence frequency of family meals in urban Japan. AB - Family commensality, or meals eaten together with family members, is a key practice to understand the socio-cultural organization of eating and family lives. Yet empirical evidence is limited outside of western societies, which have different household structures, work styles, and socio-cultural constructions of the practice. This study examined frequencies of family commensality based on 242 surveys of Japanese adults aged between 20 and 85 in two metropolitan areas. Results showed that family commensality is less frequent not only among those living alone, but also among those living with only non-partners including adult children, parents, and non-family members, than among those living with partners. Full-time employment was associated with late dinner times on weekdays. Later weekday dinner times were strongly associated with reduced frequency of dinners together. Late dinners have become commonplace among full-time workers in postwar Japan, and the peak dinner time in Japan occurs later than in other developed countries. Thus, work and lifestyle constraints impacting schedules appear to influence the frequency of family commensality. Our results suggest that frequencies of family commensality are influenced by co-residents and work styles of participants rather than household sizes. The idea that reduction of household size drives reduction of family commensality may be biased by previous studies conducted in western countries where most people reside in either single or nuclear households. Our study highlights complex determinants of family commensality, beyond presence of other household members, and demonstrates a need for rigorous investigation of family commensality across cultures. PMID- 29447995 TI - How effective are messages and their characteristics in changing behavioural intentions to substitute plant-based foods for red meat? The mediating role of prior beliefs. AB - By means of a population-based survey experiment, we analysed the effectiveness of two message characteristics - message framing and the refutation of misinformation - in persuading respondents to reduce their consumption of red meat and increase that of plant-based alternatives. We also tested whether the effects of those two message characteristics were moderated by prior beliefs about the health and climate impacts of red meat consumption. The data were collected with an online survey of the adult population living in Finland (N = 1279). We found that messages had a small but desired effect on intentions when the effect of prior beliefs was taken into account, but that that effect was strongly moderated by prior beliefs. In particular, messages changed behavioural intentions among the "meat-sceptics" (i.e., those believing relatively strongly in the negative health and climate effects of meat consumption) but not among the "meat believers" (defined symmetrically). The combination of frames and refutation of misinformation were not found to be more effective strategies than the provision of information through single-framed, one-sided messages. We found limited evidence that the way a message was formulated determined its effectiveness in changing behaviours. PMID- 29447996 TI - Sleep, food cravings and taste. AB - OBJECTIVE: Taste is influenced by factors from our environment, psychology, and from our own physiological state. The objective of the study was to determine whether sleep influences our sense of taste or our cravings for food. METHOD: 57 healthy panelists, predominantly of college age, submitted to sleep tracking, and subsequently underwent a series of sensory tests, using basic prototypic tastants, as well as real foods. Panelists were also evaluated to quantify food cravings, using both the Leeds Food Preference Questionnaire, and the Control of Eating Questionnaire. RESULTS: Umami (p = 0.025, F = 5.301) and sour (p = 0.037, F = 4.591) taste were intensified in those rating sleepiness higher, while this group also reported higher implicit wanting for high fat sweet foods (p = 0.011, Wald chi-sq = 14.937). Craving for sweet or savory also associated with a number of measures of taste response to real foods. CONCLUSIONS: Results imply that a lack of sleep may induce cravings for unhealthy foods, and that foods high in umami or sour taste may be experienced differently due to alterations in taste function. Results imply that feeding behavior may be influenced by a lack of sleep, acting at least partially through our sense of taste. PMID- 29447997 TI - Multisensory flavor perception: The relationship between congruency, pleasantness, and odor referral to the mouth. AB - Our hedonic response to a food is determined by its flavor, an inherently multisensory experience that extends beyond the mere addition of its odor and taste. While congruency is known to be important for multisensory processes in general, little is known about its specific role in flavor processing. The aim of the present study was to delineate the effects of odor-taste congruency on two central aspects of flavor: odor referral (or mislocalization) to the mouth, and pleasantness. We further aimed to test whether an eventual effect on pleasantness was mediated by odor referral. Aqueous solutions containing odors and tastes were prepared to create food-like stimuli with varying degrees of congruency, ranging from maximally incongruent to maximally congruent in nine steps. Thirty participants reported where they perceived the odors, and how much they liked the solutions. Congruency had a positive linear effect both on odor referral to the oral cavity and on pleasantness. However, the effect of congruency on pleasantness was not mediated by odor referral. These results indicate that as an odor-taste mixture approximates a mental representation of a familiar food, its components are increasingly merged into one perceptual object sensed in the mouth. In parallel, the mixture is evaluated as increasingly pleasant, which promotes consumption of familiar foods that have been determined through experience to be non-toxic. While the modulatory role of congruency on pleasantness and odor referral was confirmed, our results also indicate that these effects arise through distinct perceptual mechanisms.

PMID- 29447999 TI - Late heartbeat-evoked potentials are associated with survival after cardiac arrest. AB - RATIONALE: Cardiac arrest (CA) is a serious condition characterized by high mortality rates, even after initial successful resuscitation, mainly due to neurological damage. Whether brain-heart communication is associated with outcome after CA is unknown. Heartbeat-evoked brain potentials (HEPs) represent neurophysiological indicators of brain-heart communication. The aim of this study was to address the association between HEPs and survival after CA. METHODS: HEPs were calculated from resting EEG/ECG in 55 CA patients 24 h after resuscitation. All patients were treated with targeted temperature management and a standardized sedation protocol during assessment. We investigated the association between HEP amplitude (180-320 ms, 455-595 ms, 860-1000 ms) and 6-month survival. RESULTS: Twenty-five of 55 patients (45%) were still alive at 6-month follow-up. Survivors showed a higher HEP amplitude at frontopolar and frontal electrodes in the late HEP interval than non-survivors. This effect remained significant after controlling for between-group differences in terms of age, Fentanyl dose, and time lag between resuscitation and EEG assessment. There were no group differences in heart rate or heart rate variability. CONCLUSION: Brain-heart communication, as reflected by HEPs, is associated with survival after CA. Future studies should address the brain-heart axis in CA. PMID- 29448000 TI - Bone marrow-derived fibrocytes promote stem cell-like properties of lung cancer cells. AB - Cancer stem cells (CSCs) represent a minor population that have clonal tumor initiation and self-renewal capacity and are responsible for tumor initiation, metastasis, and therapeutic resistance. CSCs reside in niches, which are composed of diverse types of stromal cells and extracellular matrix components. These stromal cells regulate CSC-like properties by providing secreted factors or by physical contact. Fibrocytes are differentiated from bone marrow-derived CD14+ monocytes and have features of both macrophages and fibroblasts. Accumulating evidence has suggested that stromal fibrocytes might promote cancer progression. However, the role of fibrocytes in the CSC niches has not been revealed. We herein report that human fibrocytes enhanced the CSC-like properties of lung cancer cells through secreted factors, including osteopontin, CC-chemokine ligand 18, and plasminogen activator inhibitor-1. The PIK3K/AKT pathway was critical for fibrocytes to mediate the CSC-like functions of lung cancer cells. In human lung cancer specimens, the number of tumor-infiltrated fibrocytes was correlated with high expression of CSC-associated protein in cancer cells. These results suggest that fibrocytes may be a novel cell population that regulates the CSC-like properties of lung cancer cells in the CSC niches. PMID- 29448001 TI - Induced pluripotent stem cells (iPSC)-derived retinal cells in disease modeling and regenerative medicine. AB - Retinal degenerative disorders are a leading cause of the inherited, irreversible and incurable vision loss. While various rodent model systems have provided crucial information in this direction, lack of disease-relevant tissue availability and species-specific differences have proven to be a major roadblock. Human induced pluripotent stem cells (iPSC) have opened up a whole new avenue of possibilities not just in understanding the disease mechanism but also potential therapeutic approaches towards a cure. In this review, we have summarized recent advances in the methods of deriving retinal cell types from iPSCs which can serve as a renewable source of disease-relevant cell population for basic as well as translational studies. We also provide an overview of the ongoing efforts towards developing a suitable in vitro model for modeling retinal degenerative diseases. This basic understanding in turn has contributed to advances in translational goals such as drug screening and cell-replacement therapies. Furthermore we discuss gene editing approaches for autologous repair of genetic disorders and allogeneic transplantation of stem cell-based retinal derivatives for degenerative disorders with an ultimate goal to restore vision. It is pertinent to note however, that these exciting new developments throw up several challenges that need to be overcome before their full clinical potential can be realized. PMID- 29448002 TI - GDF11 expression in the adult rat central nervous system. AB - Growth differentiation factor 11 (GDF11), also known as bone morphogenetic protein 11 (BMP11), is a member of the transforming growth factor beta (TGF-beta) superfamily. Although GDF11 plays pivotal roles during development, including anterior/posterior patterning, formation of the kidney, stomach, spleen and endocrine pancreas, little information is available for GDF11 expression in the adult central nervous system (CNS). We, thus, investigated GDF11 expression in the adult rat CNS using immunohistochemistry. GDF11 was intensely expressed in most neurons and their axons. Furthermore, we found that astrocytes and ependymal cells also express GDF11 protein. These data indicate that GDF11 is widely expressed throughout the adult CNS, and its abundant expression in the adult brain strongly supports the idea that GDF11 plays important roles in the adult brain. PMID- 29448003 TI - Increased hippocampal-prefrontal functional connectivity in insomnia. AB - Insomnia Disorder (ID) is the second-most common mental disorder and has a far reaching impact on daytime functioning. A meta-analysis indicates that, of all cognitive domains, declarative memory involving the hippocampus is most affected in insomnia. Hippocampal functioning has consistently been shown to be sensitive to experimental sleep deprivation. Insomnia however differs from sleep deprivation in many aspects, and findings on hippocampal structure and function have been equivocal. The present study used both structural and resting-state functional Magnetic Resonance Imaging in a larger sample than previously reported to evaluate hippocampal volume and functional connectivity in ID. Included were 65 ID patients (mean age = 48.3 y +/- 14.0, 17 males) and 65 good sleepers (mean age = 44.1 y +/- 15.2, 23 males). Insomnia severity was assessed with the Insomnia Severity Index (ISI), subjective sleep with the Consensus Sleep Diary (CSD) and objective sleep by two nights of polysomnography (PSG). Seed-based analysis showed a significantly stronger connectivity of the bilateral hippocampus with the left middle frontal gyrus in ID than in controls (p = .035, cluster based correction for multiple comparisons). Further analyses across all participants moreover showed that individual differences in the strength of this connectivity were associated with insomnia severity (ISI, r = 0.371, p = 9.3e-5) and with subjective sleep quality (CSD sleep efficiency, r = -0.307, p = .009) (all p FDR-corrected). Hippocampal volume did not differ between ID and controls. The findings indicate more severe insomnia and worse sleep quality in people with a stronger functional connectivity between the bilateral hippocampus and the left middle frontal gyrus, part of a circuit that characteristically activates with maladaptive rumination and deactivates with sleep.

PMID- 29448005 TI - Ratio of muscle mass to fat mass assessed by bioelectrical impedance analysis is significantly correlated with liver fat accumulation in patients with type 2 diabetes mellitus. AB - AIMS: Obesity and ectopic fat accumulation are important conditions of type 2 diabetes mellitus (T2DM). Our aim was to determine whether bioelectrical impedance body composition analysis combined with blood test results could estimate liver ectopic fat accumulation in patients with treatment-naive T2DM. METHODS: Subjects were 119 untreated T2DM patients. Computed tomography scans were performed to calculate the liver to spleen attenuation ratio (L/S ratio) as a measure of liver fat accumulation, with excess liver fat accumulation defined as an L/S ratio <1.0. Elementary body composition was measured by bioelectrical impedance analysis using InBody770. RESULTS: The Nagelkerke R2 test showed that the muscle mass/fat mass ratio (muscle/fat ratio) was the most suitable variable among anthropometric factors and body component indexes for estimating liver fat accumulation. The muscle/fat ratio was significantly correlated with the L/S ratio (rho = 0.4386, P < 0.0001). Multivariable logistic regression analysis showed that the muscle/fat ratio (odds ratio 0.40, 95% confidence interval 0.22 0.73, P < 0.01) and alanine aminotransferase (odds ratio 1.06, 95% confidence interval 1.02-1.10, P < 0.01) were independently and significantly associated with liver fat accumulation. In receiver operating characteristic curve analysis, the cutoff value of the muscle/fat ratio for excess liver fat accumulation was 2.34. CONCLUSION: In patients with treatment-naive T2DM, the muscle/fat ratio and ALT are useful for estimating the presence of excess liver fat accumulation in daily clinical practice. PMID- 29448006 TI - Plasma triglycerides as a risk factor for chronic kidney disease in type 2 diabetes mellitus: Evidence from northeastern Thailand. AB - AIMS: To investigate the observational association between plasma triglyceride and CKD in patients with T2DM. METHODS: A hospital-based retrospective registry was used to obtain data of 3,748 T2DM patients from May 2016 to October 2016. Anthropometric measurements and biochemical reports of T2DM patients with CKD were obtained by data extraction of medical records. CKD was defined according to the estimated glomerular filtration rate (eGFR< 60 mL/min/1.73 m2). Multiple logistic regression was used to determine the association between plasma triglyceride and CKD. RESULTS: The mean age of the participants was 61.4 +/- 11.0 years, and a majority of them was female (64%) with poor glycemic control (83%), increased plasma triglyceride (51%) and 27% of T2DM patients had CKD. There was a significant trend towards deteriorating renal function (lower eGFR) with categorically raised triglyceride levels. After controlling for age, sex and other confounders, 'borderline high' (adjusted odds ratio (OR): 1.24, 95% confidence interval (CI): 1.01-1.54), 'high' (adjusted OR: 1.52, 95% CI: 1.24 1.85) and 'very high' (adjusted OR: 3.40, 95% CI: 1.94-5.94) triglyceride level groups had higher likelihood to have CKD compared to normal triglyceride level. CONCLUSION: CKD was associated with a higher level of plasma triglyceride among patients with T2DM. These results support the rationale to screen and manage increased triglyceride in routine clinical practices among persons with diabetes to prevent CKD.

PMID- 29448008 TI - Insecticidal activity, putative binding proteins and histopathological effects of Bacillus thuringiensis Vip3(459) toxin on the lepidopteran pest Ectomyelois ceratoniae. AB - The carob moth, Ectomyelois ceratoniae, is an important agricultural pest that is susceptible to the Vip3(459) protein. The insecticidal activity, evaluated against this lepidopteran pest, displayed an LC50 value of about 28 ng/cm2. The investigation of the mode of action of this B. thuringiensis protein demonstrated that the active form of this toxin bound to putative receptors in the BBMV of E. ceratoniae. Ligand blotting experiment proved that Vip3(459) specifically bound to two proteins of about 53 and 57 kDa, located on the midgut. This specific binding caused perturbations in midgut tissues. The histopathology of 20 midguts from Vip3(459)-feeding larvae showed cytoplasm vacuolization, brush border membrane destruction, vesicle formation in the apical region and cellular disintegration. These findings suggested that B. thuringiensis Vip3(459) could be a promising biocontrol agent to eradicate E. ceratoniae and to prevent emergence of resistance. PMID- 29448009 TI - OpenStreetMap data for alcohol research: Reliability assessment and quality indicators. AB - There is a growing interest in using OpenStreetMap [OSM] data in health research. We evaluate the usefulness of OSM data for researching the spatial availability of alcohol, a field which has been hampered by data access difficulties. We find OSM data is about 50% complete, which appears adequate for replicating findings from other studies using alcohol licensing data. Further, we show how OSM quality metrics can be used to select areas with more complete alcohol data. The ease of access and use may create opportunities for analysts and researchers seeking to understand broad patterns of alcohol availability. PMID- 29448010 TI - Improved Outcomes in Management of Hypoplastic Left Heart Syndrome Associated With Congenital Diaphragmatic Hernia: an Algorithmic Approach. AB - Hypoplastic left heart syndrome (HLHS) is the second most common congenital heart disease associated with congenital diaphragmatic hernia (CDH). The reported survival rate of neonates with CDH and HLHS is only 1%-5%. We review our experience with CDH and HLHS and compare our outcomes with published literature. Retrospective review of all neonates with CDH and HLHS at our institution over a 10-year period was performed. The morphology of cardiac and diaphragm defects, clinical course, treatment strategies, and outcomes were reviewed, and an algorithmic approach was proposed. Five patients with CDH and HLHS were treated between 2006 and 2016. All had mitral stenosis with aortic stenosis. Four patients had a left-sided Bochdalek diaphragmatic hernia and 1 patient had a large bilateral Morgagni hernia. Two (2/4) of the Bochdalek hernias were associated with significant pulmonary hypoplasia and required patch closure of the CDH; both were palliated with percutaneous ductal stents and both died. Three patients underwent primary Norwood operation followed by repair of less severe CDH defect. All 3 patients are currently well and have survived bidirectional Glenn anastomosis; one patient is well after Fontan operation. Successful palliation of neonates with HLHS and associated CDH is possible in the current era. Outcome is determined primarily by the severity of the CDH and the degree of associated pulmonary hypoplasia. An algorithmic team approach is helpful in management of this difficult group of patients. PMID- 29448011 TI - Oceanographic upwelling conditions influence signaling pathways involved in muscle growth of intertidal fish. AB - Few studies have addressed the impact of the upwelling oceanographical conditions on biological processes, such as growth, using a molecular and physiological approach. Upwelling conditions are characterized by low temperature seawater and high nutrient availability, which represents an ideal opportunity to understand how habitat modulates animal performance at different levels of biological complexity. We aimed to assess intraspecific variations in weight, oxygen consumption, protein content, and key signaling pathways involved in muscle growth (protein kinase B (AKT) and extracellular signal-regulated kinase (ERK)) under experimental trials considering high/low seawater temperatures with full/restricted food rations. For this purpose, we studied Girella laevifrons, one of the most abundant fish species inhabiting rocky intertidal zones along the Eastern South Pacific coasts. Using fish obtained from upwelling (U) and non upwelling (NU) zones, we reported that U animals displayed higher growth performance during both contrasting trials, with a weight gain (~3 g), lower oxygen consumption (~12%), and higher protein contents (~20%). Only ERK showed significant differences during the trials (~2-fold downregulation between NU and U fish). We also found that U fish increased protein ubiquitination in high water temperature and restricted food ration in contrast to NU fish. Our results help to elucidate how upwelling conditions may influence fish growth at physiological and molecular levels. Still, future analyses are necessary to improve the information regarding the impact of U and NU condition on animals, as well as the possible applications of this data in the aquaculture industry. PMID- 29448012 TI - Clogging in staked-in needle pre-filled syringes (SIN-PFS): Influence of water vapor transmission through the needle shield. AB - Staked-in needle pre-fillable syringes (SIN-PFS) are a convenient delivery system widely established in the growing pharmaceutical market. Under specific storage conditions, the needle of PFS containing high concentration drug product (DP) solution is prone to clogging, which prevents administration of the liquid. The purpose of this study is to clarify the clogging phenomenon of SIN-PFS and to elucidate the role of water vapor transmission via the needle shield. The presence of liquid within needles is a prerequisite condition for clogging and was investigated non-invasively by neutron imaging (NI) to confirm that liquid can migrate into the needle under certain processing conditions. The water vapor transmission rate (WVTR) of different needle shields was measured and the impact of temperature and relative humidity (rH) on the WVTR was investigated on sheets with the same composition as used in commercial needle shields. Our study clearly showed that the partial vapor pressure difference (DeltaPP) across the needle shield is the dominant driving factor for water vapor transmission. A linear correlation between DeltaPP and WVTR was found and a model to predict the water vapor transmission for PFS under specific storage conditions was developed. The impact of the WVTR on needle clogging was confirmed by clogging tests performed on SIN-PFS stored under different conditions. Thereby, we clearly show that high water loss induced by higher WVTR can be correlated to an increased occurrence of needle clogging. In conclusion, the WVTR of the needle shield plays a key role in needle clogging and the established WVTR model can be employed to assess the clogging risk for product development. PMID- 29448013 TI - Antibiotic resistance and molecular characterization of shigella isolates recovered from children aged less than 5 years in Manhica, Southern Mozambique. AB - The objective of this study was to assess antibiotic resistance and the molecular epidemiology of shigella isolates from a case-control study of diarrhoea, conducted from 2007 to 2012 in children aged less than 5 years in Manhica district, southern Mozambique. All isolates were tested for antimicrobial susceptibility using the disc diffusion method. Polymerase chain reaction was used to detect different molecular mechanisms of antibiotic resistance. Serotyping was performed using specific antisera. The clonal relationship of Shigella flexneri and Shigella sonnei was assessed by pulsed-field gel electrophoresis (PFGE). Of the 67 shigella isolates analysed, 59 were diarrhoeal cases and eight were controls. S. flexneri (70.1%; 47/67) was the most common species, followed by S. sonnei (23.9%; 16/67). The most prevalent S. flexneri serotypes were 2a (38.3%; 18/47), 6 (19.2%; 9/47) and 1b (14.9%; 7/47). High rates of antimicrobial resistance were observed for trimethoprim-sulfametoxazole (92.5%; 62/67), tetracycline (68.7%; 46/67), chloramphenicol (53.7%; 36/67) and ampicillin (50.7%; 34/67). Multi-drug resistance (MDR) was present in 55.2% (37/67) of the isolates and was associated with a case fatality rate of 8.1% (3/37). PFGE revealed 22 clones (16 S. flexneri and 6 S. sonnei), among which P1 (31.9%; 15/47), P9 (17%; 8/47) and P2 (10.6%; 5/47) were the most prevalent clones of S. flexneri. In conclusion, S. flexneri was the most prevalent species, with MDR isolates mainly belonging to three specific clones (P1, P9 and P2). The case fatality rate observed among MDR isolates is a matter of concern, indicating the need for appropriate treatment. PMID- 29448015 TI - Irregularity and lack of p waves in short tachycardia episodes predict atrial fibrillation and ischemic stroke. AB - BACKGROUND: Atrial fibrillation (AF) is defined as an irregular supraventricular tachycardia (SVT) without p waves, with duration >30 seconds. Whether AF characteristics during short SVT episodes predict AF and stroke is not known. OBJECTIVE: The purpose of this study was to determine whether irregularity and lack of p waves, alone or in combination, during short SVT episodes increase the risk of incident AF and ischemic stroke. METHODS: The population-based Malmo Diet and Cancer study includes 24-hour ECG screening of 377 AF-free individuals (mean age 64.5 years; 43% men) who were prospectively followed for >13 years. There were 65 AF events and 25 ischemic stroke events during follow-up. Subjects with an SVT episode >=5 beats were identified, and the longest SVT episode was assessed for irregularity and lack of p waves. The association between SVT classification and AF and stroke was assessed using multivariable adjusted Cox regression. RESULTS: The incidence of AF increased with increasing abnormality of the SVTs. The risk-factor adjusted hazard ratio for AF was 4.95 (95% confidence interval 2.06-11.9; P <.0001) for those with short irregular SVTs (<70 beats) without p waves. The incidence of ischemic stroke was highest in the group with regular SVT episodes without p waves (hazard ratio 14.2; 95% confidence interval 3.76-57.6; P <.0001, adjusted for age and sex). CONCLUSION: Characteristics of short SVT episodes detected at 24-hour ECG screening are associated with incident AF and ischemic stroke. Short irregular SVTs without p waves likely represent early stages of AF or atrial myopathy. Twenty-four-hour ECG could identify subjects suitable for primary prevention efforts. PMID- 29448014 TI - Intrauterine inflammation reduces postnatal neurogenesis in the hippocampal subgranular zone and leads to accumulation of hilar ectopic granule cells. AB - Prenatal inflammation is associated with poor neurobehavioral outcomes in exposed offspring. A common route of exposure for the fetus is intrauterine infection, which is often associated with preterm birth. Hippocampal development may be particularly vulnerable to an inflammatory insult during pregnancy as this region remains highly neurogenic both prenatally and postnatally. These studies sought to determine if intrauterine inflammation specifically altered hippocampal neurogenesis and migration of newly produced granule neurons during the early postnatal period. Microglial and astroglial cell populations known to play a role in the regulation of postnatal neurogenesis were also examined. We show that intrauterine inflammation significantly reduced hippocampal neurogenesis between postnatal days 7 (P7) and P14 as well as decreased granule cell density at P28. Ectopic migration of granule cells was observed in LPS-exposed mice at P14, but not at P28. Intrauterine inflammation had no effect on hippocampal astrocyte or microglia density or on apoptosis rate at the postnatal time points examined. Thus, exposure to intrauterine inflammation disrupts early postnatal neurogenesis and leads to aberrant migration of newly born granule cells. PMID- 29448016 TI - Intestinal immunity suppresses carrying capacity of rats for the model tapeworm, Hymenolepis diminuta. AB - Hymenolepis diminuta is a parasitic tapeworm of the rat small intestine and is recognized as a useful model for the analysis of cestode-host interactions. In this study, we analyzed factors affecting the biomass of the tapeworm through use of rat strains carrying genetic mutations, namely X-linked severe combined immunodeficiency (xscid; T, B and NK cells deficiency), nude (rnu; T cell deficiency), and mast cell deficient rats. The worm biomass of F344-xscid rats after infection with 5 cysticercoids was much larger than control F344 rats from 3 to 8 weeks. The biomass of F344-rnu rats was also larger than the controls, but was intermediate between F344-xscid and control rats. These observations demonstrated that host immunity can control the maximal tapeworm biomass, i.e., carrying capacity, of the rat small intestine. Both T cell and other immune cells (B and NK cells) have roles in determining the carrying capacity of tapeworms. Total worm biomass and worm numbers in mast cell deficient rats (WsRC-Ws/Ws) were not significantly different from control WsRC-+/+ rats after 3 and 6 weeks of primary infection. Mast cell deficient rats displayed reinfection resistance for worm biomass but not worm expulsion. These findings suggest that the mast cell has a role for controlling the biomass of this tapeworm in reinfection alone, but does not affect the rate of worm expulsion. Overall, our findings indicate that the mast cell is not a major effector cell for the control of the carrying capacity of tapeworms. The identity of the major effector cell remains unknown. PMID- 29448017 TI - Fetal bovine serum-free cryopreservation methods for clinical banking of human adipose-derived stem cells. AB - The use of fetal bovine serum (FBS) as a cryopreservation supplement is not suitable for the banking of mesenchymal stem cells (MSCs) due to the risk of transmission of disease as well as xenogeneic immune reactions in the transplanted host. Here, we investigated if human serum albumin (HSA), human serum (HS), or knockout serum replacement (KSR) can replace FBS for the cryopreservation of MSCs. In addition, we examined the characteristics of MSCs after multiple rounds of cryopreservation. Human adipose-derived stem cells (ASCs) cryopreserved with three FBS replacements, 9% HSA, 90% HS, or 90% KSR, in combination with 10% dimethyl sulfoxide (Me2SO) maintained stem cell properties including growth, immunophenotypes, gene expression patterns, and the potential to differentiate into adipogenic, osteogenic, and chondrogenic lineages, similar to ASCs frozen with FBS. Moreover, the immunophenotype, gene expression, and differentiation capabilities of ASCs were not altered by up to four freeze-thaw cycles. However, the performance of three or four freeze-thaw cycles significantly reduced the proliferation ability of ASCs, as indicated by the longer population doubling time and reduced colony-forming unit-fibroblast frequency. Together, our results suggest that HSA, HS, or KSR can replace FBS for the cryopreservation of ASCs, without altering their stemness, and should be processed with no more than two freeze-thaw cycles for clinical approaches.

AB - Intracellular ice formation (IIF) is the major cause of death in cells subjected to freezing. The occurrence of intracellular ice prevents the penetration of light into the camera and makes the image dark. Therefore, the gray-level variation can reflect the IIF. However, cell deformation is accompanied with IIF, especially for larger cells. It is necessary to account this entire phenomenon together in a single method. In this paper, the normalized parameter C defined by the gray-level variation depending on the displacement was defined to reflect the gray-level change of each pixel point in the region of interest of the image. The process of IIF of onion epidermal cells and 293T cells was analyzed by this method.

AB - In 2004 migration and mortality for unknown reasons of the herbivorous Black necked swan (Cygnus melancorhyphus (Molina, 1782)) occurred within the Rio Cruces wetland (southern Chile), a Ramsar Site and nature sanctuary. Before 2004, this wetland hosted the largest breeding population of this water bird in the Neotropic Realm. The concurrent decrease in the spatial occurrence of the aquatic plant Egeria densa Planch. 1849 - the main food source of swans - was proposed as a cause for swan migration and mortality. Additionally, post-mortem analyses carried out on swans during 2004 showed diminished body weight, high iron loads and histopathological abnormalities in their livers, suggesting iron storage disease. Various hypotheses were postulated to describe those changes; the most plausible related to variations in water quality after a pulp mill located upstream the wetland started to operate in February 2004. Those changes cascaded throughout the stands of E. densa whose remnants had high iron contents in their tissues. Here we present results of a long-term monitoring program of the wetland components, which show that swan population abundance, body weights and histological liver conditions recovered to pre-disturbance levels in 2012. The recovery of E. densa and iron content in plants throughout the wetland, also returned to pre-disturbance levels in the same 8-year time period. These results show the temporal scale over which resilience and natural restoring processes occur in wetland ecosystems of temperate regions such as southern Chile. PMID- 29448020 TI - An anaerobic membrane bioreactor - membrane distillation hybrid system for energy recovery and water reuse: Removal performance of organic carbon, nutrients, and trace organic contaminants. AB - In this study, a direct contact membrane distillation (MD) unit was integrated with an anaerobic membrane bioreactor (AnMBR) to simultaneously recover energy and produce high quality water for reuse from wastewater. Results show that AnMBR could produce 0.3-0.5L/g CODadded biogas with a stable methane content of approximately 65%. By integrating MD with AnMBR, bulk organic matter and phosphate were almost completely removed. The removal of the 26 selected trace organic contaminants by AnMBR was compound specific, but the MD process could complement AnMBR removal, leading to an overall efficiency from 76% to complete removal by the integrated system. The results also show that, due to complete retention, organic matter (such as humic-like and protein-like substances) and inorganic salts accumulated in the MD feed solution and therefore resulted in significant fouling of the MD unit. As a result, the water flux of the MD process decreased continuously. Nevertheless, membrane pore wetting was not observed throughout the operation.

AB - This study aims to assess the effects and the mechanisms of silica nanoparticles (SiNPs) on hepatotoxicity in both normal and metabolic syndrome mouse models induced by fructose. Here, we found that SiNPs exposure lead to improved insulin resistance in metabolic syndrome mice, but markedly worsened hepatic ballooning, inflammation infiltration, and fibrosis. Moreover, SiNPs exposure aggravated liver injury in metabolic syndrome mice by causing serious DNA damage. Following SiNPs exposure, liver superoxide dismutase and catalase activities in metabolic syndrome mice were stimulated, which is accompanied by significantly increased malondialdehyde and 8-hydroxy-2-deoxyguanosine levels as compared to normal mice. Scanning electron microscope (SEM) revealed that SiNPs were more readily deposited in the liver mitochondria of metabolic syndrome mice, resulting in more severe mitochondrial injury as compared to normal mice. We speculated that SiNPs induced mitochondrial injury might be the cause of hepatic oxidative stress, which further lead to a series of liver lesions as observed in mice following SiNPs exposure. Based on these results, it is likely that SiNPs will increase the risk and severity of liver disease in individuals with metabolic syndrome. Therefore, SiNPs should be used cautiously in food additives and clinical settings. PMID- 29448022 TI - Photosynthesis and mineralogy of Jania rubens at low pH/high pCO2: A future perspective. AB - Corallinales (Rhodophyta) are high Mg-calcite macroalgae and are considered among the most vulnerable organisms to ocean acidification (OA). These sensitive species play fundamental roles in coastal systems as food source and settlement promoters as well as being involved in reef stabilization, and water carbonate balance. At present only a few studies are focused on erect calcifying macroalgae under low pH/high pCO2 and the contrasting results make difficult to predict the ecological consequences of the OA on the coralline algae. In this paper the physiological reasons behind the resistance of Jania rubens, one of the most common calcareous species, to changing ocean pH are analysed. In particular, we studied the photosynthetic and mineralogical response of J. rubens after a three week transplant in a natural CO2 vent system. The overall results showed that J. rubens could be able to survive under predicted pH conditions even though with a reduced fitness; nevertheless physiological limits prevent the growth and survival of the species at pH6.7. At low pH (i.e. pH7.5), the maximum and effective PSII efficiency decreased even if the increase of Rubisco expression suggests a compensation effort of the species to cope with the decreased light driven products. In these circumstances, a pH-driven bleaching phenomenon was also observed. Even though the photosynthesis decreased at low pH, J. rubens maintained unchanged the mineralogical composition and the carbonate content in the cell wall, suggesting that the calcification process may also have a physiological relevance in addition to a structural and/or a protective role. Further studies will confirm the hypotheses on the functional and evolutionary role of the calcification process in coralline algae and on the ecological consequences of the community composition changes under high pCO2 oceans. PMID- 29448023 TI - Simulating spatial distribution of coastal soil carbon content using a comprehensive land surface factor system based on remote sensing. AB - Surface soil carbon content (SCC) in coastal area is affected by complex factors, and revealing the SCC spatial distribution is considerably significant for judging the quantity of stored carbon and identifying the driving factors of SCC variation. A comprehensive land surface factor system (CLSFS) was established; it utilized the ecological significances of remote sensing data and included four class factors, namely, spectrum information, ecological indices, spatial location, and land cover. Different simulation algorithms, including single factor regression (SFR), multiple-factor regression (MFR), partial least squares regression (PLSR), and back propagation neural network (BPNN), were adopted to conduct the surface (0-30cm) SCC mapping in the Yellow River Delta in China, and a 10-fold cross validation approach was used to validate the uncertainty and accuracy of the algorithms. The results indicated that the mean simulated standard deviations were all <0.5g/kg and thus showed a low uncertainty; the mean root mean squared errors based on the simulated and measured SCC were 3.88g/kg (SFR), 3.85g/kg (PLSR), 3.67g/kg (MFR), and 2.78g/kg (BPNN) with the BPNN exhibiting a high accuracy compared to similar studies. The mean SCC was 17.40g/kg in the Yellow River Delta with distinct spatial heterogeneity; in general, the SCC in the alongshore regions, except for estuaries, was low, and that in the west of the study area was high. The mean SCCs in farmland (18.31g/kg) and wetland vegetation (17.98g/kg) were higher than those in water area (16.07g/kg), saltern (15.61g/kg), and bare land (14.71g/kg). Land-sea interaction and human activity jointly affected the SCC spatial distribution. The CLSFS was proven to have good applicability, and can be widely used in simulating the SCC spatial distribution in coastal areas. PMID- 29448024 TI - How to avoid eutrophication in coastal seas? A new approach to derive river specific combined nitrate and phosphate maximum concentrations. AB - Since 1950, increase in nitrogen (N) and phosphorus (P) river loadings in the North-East Atlantic (NEA) continental seas has induced a deep change in the marine coastal ecosystems, leading to eutrophication symptoms in some areas. In order to recover a Good Ecological Status (GES) in the NEA, as required by European Water Framework Directive (WFD) and Marine Strategy Framework Directive (MSFD), reductions in N- and P-river loadings are necessary but they need to be minimal due to their economic impact on the farming industry. In the frame of the "EMoSEM" European project, we used two marine 3D ecological models (ECO-MARS3D, MIRO&CO) covering the Bay of Biscay, the English Channel and the southern North Sea to estimate the contributions of various sources (riverine, oceanic and atmospheric) to the winter nitrate and phosphate marine concentrations. The various distributed descriptors provided by the simulations allowed also to find a log-linear relationship between the 90th percentile of satellite-derived chlorophyll concentrations and the "fully bioavailable" nutrients, i.e. simulated nutrient concentrations weighted by light and stoichiometric limitation factors. Any GES threshold on the 90th percentile of marine chlorophyll concentration can then be translated in maximum admissible 'fully bioavailable' DIN and DIP concentrations, from which an iterative linear optimization method can compute river-specific minimal abatements of N and P loadings. The method has been applied to four major river groups, assuming either a conservative (8MUgChlL-1) or a more socially acceptable (15MUgChlL-1) GES chlorophyll concentration threshold. In the conservative case, maximum admissible winter concentrations for nutrients correspond to marine background values, whereas in the lenient case, they are close to values recommended by the WFD/MSFD. Both models suggest that to reach chlorophyll GES, strong reductions of DIN and DIP are required in the Eastern French and Belgian-Dutch river groups. PMID- 29448025 TI - Remote sensing of the urban heat island effect in a highly populated urban agglomeration area in East China. AB - Increasingly urban agglomeration, representing a group of cities with a compact spatial organization and close economic links, can rise surface temperature in a continuous area due to decreasing distance between cities. Significant progress has been made in elucidating surface urban heat island intensity (SUHII) of a single city or a few big cities, but the SUHII's patterns remain poorly understood in urban agglomeration regions. Using Aqua/Terra MODIS data over 2010 2015, we examined the SUHII variations and their drivers in Yangtze River Delta Urban Agglomeration (YRDUA) of east China. Instead of using the widely-used suburban/rural areas as references, this study predicted the unaffected reference temperature wall-to-wall from natural forests by a simple planar surface model. Results indicated that urbanization warmed the land surface regardless of urban area size in YRDUA, with the SUHII clearly larger in the day (2.6+/-0.9 degrees C) than night (0.7+/-0.4 degrees C). The SUHII varied markedly by cities, yet the largest did not happen in the presumed core cities. Also, the SUHII differed greatly in a seasonal cycle, with summer-winter difference of 4.2+/-0.9 degrees C and 2.0+/-0.5 degrees C in the day and night, respectively. Particularly, cooling effects of urban areas were observed in winter for the majority of cities at night. These spatiotemporal patterns depend strongly on the background climate (precipitation and air temperature), vegetation activity, surface albedo, and population density, with contrast mechanisms during the day and night. Further, we showed that ignoring urban agglomeration effect (using suburban/rural areas as the unaffected references) would lead to large biases of SUHII estimates in terms of magnitude and spatial distribution. Our results emphasize the necessity of considering cities altogether when assessing the urbanization effects on climate in an urban agglomeration area. PMID- 29448026 TI - Characterization and source identification of fine particulate matter in urban Beijing during the 2015 Spring Festival. AB - The Spring Festival (SF) is the most important holiday in China for family reunion and tourism. During the 2015 SF an intensive observation campaign of air quality was conducted to study the impact of the anthropogenic activities and the dynamic characteristics of the sources. During the study period, pollution episodes frequently occurred with 12days exceeding the Chinese Ambient Air Quality Standards for 24-h average PM2.5 (75MUg/m3), even 8days with exceeding 150MUg/m3. The daily maximum PM2.5 concentration reached 350MUg/m3 while the hourly minimum visibility was <0.8km. Three pollution episodes were selected for detailed analysis including chemical characterization and diurnal variation of the PM2.5 and its chemical composition, and sources were identified using the Positive Matrix Factorization model. The first episode occurring before the SF was characterized by more formation of SO42- and NO3- and high crustal enrichment factors for Ag, As, Cd, Cu, Hg, Pb, Se and Zn and seven categories of pollution sources were identified, whereby vehicle emission contributed 38% to the PM2.5. The second episode occurring during the SF was affected heavily by large-scale firework emissions, which led to a significant increase in SO42-, Cl-, OC, K and Ba; these emissions were the largest contributor to the PM2.5 accounting for 36%. During the third episode occurring after the SF, SO42-, NO3-, NH4+ and OC were the major constituents of the PM2.5 and the secondary source was the dominant source with a contribution of 46%. The results provide a detailed understanding on the variation in occurrence, chemical composition and sources of the PM2.5 as well as of the gaseous pollutants affected by the change in anthropogenic activities in Beijing throughout the SF. They highlight the need for limiting the firework emissions during China's most important traditional festival. PMID- 29448028 TI - Humoral immune parameters in serum of gilthead seabream (Sparus aurata L.) after induced skin injury. AB - Skin lesions contribute to significant rates of morbidity and mortality in fish because they permit the entry of pathogens. Different seric immune parameters (IgM level, protease, antiprotease, peroxidase and lysozyme) and bactericidal activity (against Vibrio harveyi and Photobacterium damsealae) of gilthead seabream (Sparus aurata L.) specimens were evaluated after experimentally wounding fish in two body locations (above or below the lateral line). The results demonstrate that the level of several immune parameters present in fish serum (IgM, proteases, peroxidase and bactericidal activity) showed statistically significant variations depending on the site of the skin wound and the time post wounding (from 0 to 7 days). However, other parameters (such as antiproteases or lysozyme) remained unaltered during the experiment and did not differs from the values recorded on control fish (non-wounded). The highest activities recorded coincided with the inflammatory healing phase. Moreover, many more significant variations were observed in fish wounded below the lateral line than in those wounded above the lateral line. The present results demonstrate the importance of skin integrity in the maintenance of fish body homeostasis. PMID- 29448029 TI - MicroRNA-874 inhibits TNF-alpha-induced remodeling in human fetal airway smooth muscle cells by targeting STAT3. AB - Pro-inflammatory cytokines-induced airway remodeling was a significant feature of asthma disease. The aim of the present study was to explore the functional significance of miR-874 in tumor necrosis factor (TNF)-alpha-treated human fetal airway smooth muscle (fASM) cells. Here, we found that TNF-alpha treatment significantly down-regulated the expression of miR-874 in fASM cells. MiR-874 overexpression markedly inhibited cell viability and migration, suppressed the expression of PCNA and Ki67, reduced the expression of collagen I and collagen III, decreased the expression and activity of matrix metalloproteinase (MMP)-9 and MMP-2, and induced an obvious elevation of tissue inhibitors of metalloproteinases (TIMPs). In addition, the increased production of interleukin (IL)-6, IL-8 and eotaxin induced by TNF-alpha were significantly inhibited by miR 874 overexpression. Signal transducers and activators of transcription (STAT) 3 was identified as a direct target of miR-874, and STAT3 overexpression partly reversed the protective effects of miR-874 against TNF-alpha-induced airway remodeling. Overall, these findings demonstrate that miR-874 inhibits TNF-alpha induced remodeling in human fASM cells at least in part by targeting STAT3. PMID- 29448030 TI - A SEP tag enhances the expression, solubility and yield of recombinant TEV protease without altering its activity. AB - Tobacco Etch Virus (TEV) protease is used in the purification of recombinant proteins, but its usage is often hampered by solubility issues. Here, we report a short, 12-residue solubility enhancing peptide (SEP) tag attached at the C terminus of TEV (TEV-C9R). We assessed the effects of the C9R tag on the biophysical and biochemical characteristics of TEV. The yield of HPLC purified TEV-C9R expressed in E. coli grown in 200 mL LB or TB media was between 10 and 13 mg, which was up to 6.5 times higher than the yield of the untagged TEV (untagged TEV). TEV-C9R was active over a pH range of 5-8, which was wider than that of the commonly used thrombin, and it remained active upon incubation at 60 degrees C much longer than the untagged-TEV, which aggregated at this temperature. Static and dynamic light scattering demonstrated the higher solubility of purified TEV C9R. Furthermore, the thermal unfolding of TEV-C9R, as assessed by circular dichroism at pH 4.7, was almost perfectly reversible, in contrast to that of untagged-TEV, which aggregated at high temperature. These results demonstrate the improved biophysical and biochemical characteristics of TEV-C9R originating from higher solubility and provide another example of how SEP tags can enhance enzyme solubility without altering its activity. PMID- 29448031 TI - Phylogeography and population genetic analyses reveal the speciation of the Tuber indicum complex. AB - Tuber indicum is an ectomycorrhizal ascomycete that produces edible ascocarps. Based on a number of specimens with known exact origin, we investigate the speciation of the Tuber indicum complex in southwest China. Internal transcribed spacer (ITS) and simple sequence repeat (SSR) markers were used in the study. Phylogeography and population genetics analyses were combined to detect 31 wild populations of the T. indicum complex. Two distinct lineages, Tuber cf. indicum and Tuber cf. himalayense, were identified in the T. indicum complex that exhibited significant phylogeographic structures and genetic differentiation. The characteristics of haplotypes distributing along the river demonstrate that the diffusion and modern distribution pattern of species was influenced by river expansion. These findings are critical for the protection of the diversity of truffles in this region. PMID- 29448032 TI - Risedronate reduces postoperative bone resorption after cementless total hip arthroplasty: A systematic review and meta-analysis. AB - OBJECTIVE: To examine the effects of risedronate for reducing periprosthetic bone loss after total hip arthroplasty (THA). METHODS: Two reviewers performed an electronic literature search for randomized controlled trial (RCTs) evaluating the risedronate in the management of periprosthetic bone loss after primary THA. The electronic databases include PubMed, Medline, Embase, Web of Science and the Cochrane Library from inception to January 2018. We assessed the risk of bias using the Cochrane risk-of-bias tool. STATA 14.0 was used to perform the meta analysis. RESULTS: Four RCTs were included in our study. Current meta-analysis indicated that postoperative reduciton of periprosthetic BMD in the risedronate group was significantly lower than that in the placebo group in zones 1, 2, 3, 4, 6, and 7. There was no increased risk of adverse effects. CONCLUSION: The administration of risedronate was associates with a significantly improved periprosthetic BMD after primary THA. No increased risk of adverse events were observed. Higher quality RCTs are still required for further research. PMID- 29448033 TI - Environmental enrichment decreases avoidance responses in the elevated T-maze and delta FosB immunoreactivity in anxiety-related brain regions. AB - Environmental enrichment (EE) is an animal management technique, which seems to improve adaptation to the experimental conditions of housing in laboratory animals. Previous studies have pointed to different beneficial effects of the procedure in the treatment of several disorders, including psychiatric conditions such as depression. The anxiolytic effects induced by EE, on the other hand, are not as clear. In fact, it has been proposed that EE acts as a mild stressor agent. To better understand the relationship of EE with anxiety-related responses, the present study exposed rats to one week of EE and subsequently tested these animals in the inhibitory avoidance and escape tasks of the elevated T-maze (ETM). In clinical terms, these responses have been respectively related to generalized anxiety and panic disorder. All animals were tested in an open field, immediately after the ETM, for locomotor activity assessment. Additionally, analysis of delta FosB protein immunoreactivity (FosB-ir) was used to map areas activated by EE exposure and plasma corticosterone measurements were performed. The results obtained demonstrate that exposure to EE for one week impaired avoidance responses, an anxiolytic-like effect, without altering escape reactions. Also, in animals submitted to the avoidance task EE exposure decreased FosB-ir in the cingulate cortex, dorsolateral and intermediate lateral septum, hippocampus (cornus of Ammon), anterior and dorsomedial hypothalamus, medial and basolateral amygdala and ventral region of the dorsal raphe nucleus. Although no behavioral differences were observed in animals submitted to the escape task, EE exposure also decreased FosB-ir in the cingulate cortex, hippocampus (dentate gyrus), lateral amygdala, paraventricular, anterior and ventromedial hypothalamus, dorsomedial periaqueductal gray and ventral and dorsal region of the dorsal raphe. No changes in corticosterone levels, however, were observed. These results contribute to a better understanding of the effects of EE on anxiety. PMID- 29448034 TI - Bombyx mori homolog of tumor suppressor p53 is involved in apoptosis-mediated antiviral immunity of B. mori cells infected with nucleopolyhedrovirus. AB - Apoptosis is important in antiviral immunity and affects viral multiplication and pathogenesis. Here, we showed that Bombyx mori cells transiently expressing B. mori homolog of the tumor suppressor p53 (Bm-p53) protein underwent apoptosis accompanied by elevated caspase-3-like protease activity and processing of B. mori Dronc (Bm-Dronc). RNAi-mediated silencing of bm-p53 expression, which significantly diminished accumulation of bm-p53 transcript and Bm-p53 protein, prevented apoptosis of B. mori cells infected with a recombinant B. mori nucleopolyhedrovirus defective in the anti-apoptotic p35 gene (vBmDeltap35) and abolished the activation of caspase-3-like protease and processing of Bm-Dronc. Apoptosis in vBmDeltap35-infected B. mori cells is associated with viral DNA replication, suggesting involvement of the DNA damage response. The Bm-p53 pro apoptotic function is also found in Spodoptera frugiperda and Lymantria dispar cells. These results indicate that apoptosis induction in vBmDeltap35-infected B. mori cells is a Bm-p53-mediated process promoted by the commencement of viral DNA replication.

AB - Oxygen plays a key role in wound healing, and hypoxia is a major cause of wound healing impairment; therefore, treatments to improve hemodynamics and increase wound oxygenation are of particular interest for the treatment of chronic wounds. This article describes the roles of oxygen and angiogenesis in wound healing as well as the tools used to evaluate tissue oxygenation and perfusion and then presents a review of nanomedicines and gene therapies designed to improve perfusion and oxygenation and accelerate wound healing. PMID- 29448036 TI - Molecular characterisation of multidrug-resistant pneumococcal clones colonising healthy children in Merida, Venezuela. AB - Genetic mechanisms of resistance, clonal composition and the occurrence of pili were analysed in 48 multidrug-resistant (MDR) pneumococci isolated from healthy children in Merida, Venezuela. Intermediate resistance to penicillin was related to variations in pbp2b and pbp2x. High-level resistance to penicillin as well as low susceptibility to cephalosporins and carbapenems were associated with alterations in pbp1a, pbp2b and pbp2x. Non-beta-lactam resistance was associated with Tn3872, Tn5253, Tn6002 and Tn2010 transposons. Macrolide-resistant strains carried ermB or mefE, but not mefA. Tetracycline- and chloramphenicol-resistant pneumococci carried tetM and cat, respectively. MDR pneumococci were related to six clonal complexes (CCs), largely CC156 or CC15. Limited diversity in pbp2a,2b,2x-RFLP profiles within each clone was observed. Conversely, detection of non-beta-lactam resistance and transposons revealed clear genetic diversity within clones. A group of non-typeable/cpsA-negative pneumococci related to the null capsule clade 1 (NCC1) carrying a Tn2009 element was found. Each NCC1 related strain showed a novel MLST allelic combination and a different pbp2a,2b,2x-RFLP profile. PI-1 (pilus type 1 rrgC gene) was present in most of the MDR pneumococci and its occurrence was commonly homogeneous within each clone. PI-1 was present in all CC242 and CC320 pneumococci, whereas it was absent in all CC37, CC81 and NCC1 isolates. CC156 and CC15 isolates showed variations in the occurrence of PI-1. Both PI-1 and the islet for pilus type 2 were present in CC320 isolates. We provide useful data to follow the evolution of clonal composition, mechanisms of antibiotic resistance and the occurrence of pili among pneumococci circulating in Merida. PMID- 29448038 TI - Molecular and biological characterization of a highly pathogenic Trypanosoma cruzi strain isolated from a patient with congenital infection. AB - Although many Trypanosoma cruzi (T. cruzi) strains isolated from a wide range of hosts have been characterized, there is a lack of information about biological features from vertically transmitted strains. We describe the molecular and biological characteristics of the T. cruzi VD strain isolated from a congenital Chagas disease patient. The VD strain was typified as DTU TcVI; in vitro sensitivity to nifurtimox (NFX) and beznidazole (BZ) were 2.88 MUM and 6.19 MUM respectively, while inhibitory concentrations for intracellular amastigotes were 0.24 MUM for BZ, and 0.66 MUM for NFX. Biological behavior of VD strain was studied in a mouse model of acute infection, resulting in high levels of parasitemia and mortality with a rapid clearence of bloodstream trypomastigotes when treated with BZ or NFX, preventing mortality and reducing parasitic load and intensity of inflammatory infiltrate in skeletal and cardiac muscle. Treatment induced parasitological cure, evaluated after immunossupression were 41% and 35% for BZ and NFX treatment respectively, suggesting a partial response to these drugs in elimination of parasite burden. This exhaustive characterization of this T. cruzi strain provides the basis for inclusion of this strain in a panel of reference strains for drug screening and adds a new valuable tool for the study of experimental T. cruzi infection. PMID- 29448039 TI - Development of siRNA mediated RNA interference and functional analysis of novel parasitic nematode-specific protein of Setaria digitata. AB - Despite the differences of the host, parasitic nematodes may share commonalities in their parasitizing genes. Setaria digitata novel protein (SDNP) is such an entity which is parasitic nematode-specific and having sequence similarities with those of W. bancrofti, B. malayi, Loa loa and Onchocerca volvulus. Post transcriptional gene silencing by siRNA mediated RNA interference (RNAi) is a widely used technique in functional genomics. Though the technique has been used in several free-living, plant and animal parasitic nematodes, it has not yet been tried out for the filarial worm S. digitata. In this study, we developed an effective siRNA delivery method by microinjection and utilized the siRNAi tool to knockdown SDNP to study the phenotypic and cellular changes associated with the interference. qPCR analysis revealed, a significant reduction of SDNP transcript levels following siRNA microinjection into S. digitata adult worms. Similarly, immunohistochemical staining indicated a reduction of SDNP protein expression. Furthermore, worms treated with siRNA showed a significant reduction of microfilariae release together with embryonic lethality by arresting an early developmental stage compared to non-treated worms. A distinct motility reduction was also observed in treated worms compared to non-treated counterparts. This is the first report of the amenability of S. digitata to the siRNA induced RNAi. The presence of inter-domain linkers of muscle-specific twitchin kinase and calcium dependent protein kinase isoform CDPK1 together with what our results revealed suggest that SDNP is most likely a protein involved in muscle movement and growth and development of the nematode. Hence SDNP has the characteristics of a potential drug target. PMID- 29448037 TI - Quantifying membrane protein oligomerization with fluorescence cross-correlation spectroscopy. AB - Fluorescence cross-correlation spectroscopy (FCCS) is an advanced fluorescence technique that can quantify protein-protein interactions in vivo. Due to the dynamic, heterogeneous nature of the membrane, special considerations must be made to interpret FCCS data accurately. In this study, we describe a method to quantify the oligomerization of membrane proteins tagged with two commonly used fluorescent probes, mCherry (mCH) and enhanced green (eGFP) fluorescent proteins. A mathematical model is described that relates the relative cross-correlation value (fc) to the degree of oligomerization. This treatment accounts for mismatch in the confocal volumes, combinatoric effects of using two fluorescent probes, and the presence of non-fluorescent probes. Using this model, we calculate a ladder of fc values which can be used to determine the oligomer state of membrane proteins from live-cell experimental data. Additionally, a probabilistic mathematical simulation is described to resolve the affinity of different dimeric and oligomeric protein controls. PMID- 29448040 TI - Comparing the therapeutic efficacy of different amphotericin B-carrying delivery systems against visceral leishmaniasis. AB - Amphotericin B (Amp) has been well-successfully used to treat against Leishmania infection, although high toxicity has been found in patients. In the present study, Amp was administered in Leishmania infantum-infected BALB/c mice by three distinct delivery systems aiming to compare their efficacy against challenge infection, as well as their side effects in a murine visceral leishmaniasis (VL) model. This product was administered in a Poloxamer P407 (Pluronic(r) F127)-based polymeric micelle system (Amp/M), in the Ambisome(r) formulation (Lip-Amp) or in a free format (free Amp). Glucantime(r) (Gluc) was used as a comparative drug. Aiming to evaluate different endpoints of the treatments, the efficacy of the compounds was investigated one and 15-days after the therapeutic regimens, determining the parasite load by a limiting dilution assay and a quantitative PCR (qPCR) technique, as well as evaluating the immune response generated in the infected and treated animals. In the results, Amp/M or Lip-Amp-treated mice presented the best outcomes, since significant parasite load reductions were found in the evaluated organs, as well as a parasite-specific Th1 immune response was observed in the animals. In addition, no hepatic or renal damage was found in these mice. On the other hand, free Amp or Gluc induced toxicity in the animals, which was associated with a low Th1 immune response. Comparatively, Amp/M was the most effective drug in our experimental model, and results showed that the Amp carrying system could be considered as a future alternative in studies against VL. PMID- 29448041 TI - VIP changes during daytime in chicken intrinsic choroidal neurons. AB - PURPOSE: Ocular autonomic control is mediated by sympathetic and parasympathetic nerve fibres. Their interactions are complemented by primary afferent nerve fibers of and intrinsic choroidal neurons (ICN). As the vasodilatative neuropeptide, vasoactive intestinal peptide (VIP), is expressed in extrinsic and intrinsic ocular neurons, it is of special interest in ophthalmic research. Since circadian changes of ocular blood flow are known in humans and birds, this study aimed at investigating VIP expression at different daytimes in chicken choroid, the preferred model species in ICN research. METHODS: 12 eyes of 12 chickens were retrieved, slaughtered at 8.00-9.30 a.m. (n = 6) and 8.00 p.m. (n = 6), respectively, and choroidal wholemounts were prepared for immunofluorescence of VIP. VIP-positive ICN of both groups were quantified and density of VIP-positive axons assessed semi-quantitatively. In 28 additional eyes retrieved in the morning (n = 14) and evening (n = 14), choroidal VIP content was determined by ELISA. Morning and evening data were analyzed statistically. NADPH-diaphorase (NADPH-d, ICN cell marker) was done at additional 12 whole mount choroids of 12 chicken, retrieved in the morning (n = 6) and evening (n = 6). RESULTS: (1) Numbers of VIP positive neurons differed significantly between morning: (239.17 +/- 113.9) and evening: (550.83 +/- 245.7; p = 0.018). (2) Numbers of VIP positive perikarya were significantly more accumulated in the temporal part of the choroid in the evening than in the morning (p = 0.026). (3) VIP positive axon density was found to be similar throughout the choroid in the morning and evening. (4) Number of NADPH-d positive neurons was not significantly different between morning (848.8 +/- 399.5) and evening (945.8 +/- 622.1, p > 0.05). (5) ELISA demonstrated a significant difference of VIP content (p = 0.012) in tissues harvested in the morning (145.41 +/- 43.3 pg/ml) compared to evening (221.44 +/- 106.3 pg/ml). CONCLUSIONS: As VIP positive axon density was similar in the morning and the evening throughout the choroid, PPG and ICN seemed to contribute equally to the axon network. Yet, changes in the total choroidal VIP content, the numbers of VIP positive perikarya, reflecting the intracellular VIP content, and their topographical distribution at two different days-times argue for a different status of activation of both neuronal sources in contrast to the equal amount of NADPHD-d positive neurons. The higher VIP content in the evening, compared to the morning, correlates with a known circadian rhythm of a lower IOP and a higher choroidal thickness at night. Thus, these changes may argue for a potential role of ICN in the regulation of ocular homeostasis and integrity. PMID- 29448042 TI - Quantitative comparisons between optical coherence tomography angiography and matched histology in the human eye. AB - The aim was to quantitatively compare retinal vascular detail as seen on optical coherence tomography angiography (OCTA) and matched histology in the human eye. 13 normal human donor eyes were used. The central retinal artery was cannulated after which human packed red blood cells were perfused through the retinal vasculature. Retinal vessels were imaged using a custom-built OCTA device during red blood cell perfusion. The eye was subsequently perfused with endothelial cell antibodies and the flat-mounted retina studied histologically using a confocal scanning laser microscope. Qualitative and quantitative comparisons of retinal vascular information as seen on OCTA and histology from the same region of interest were performed. Gradable OCTA images were acquired from 4 of 13 eyes with mean postmortem-to-OCTA imaging time of 4.5 +/- 1.3 h 23 pairs of OCTA histology matched images were evaluated. The retinal arteries and veins had similar pixel intensity on OCTA images. The diameter of retinal veins was significantly greater than its paired artery on OCTA (P < 0.001). The density of vascular structures on OCTA (40.2% +/- 10.1%) was significantly less than matched histology (52.1% +/- 9.3%, P < 0.001). Mean capillary diameter on OCTA (10.2 +/- 2.4 MUm) was significantly greater than histology (8.2 +/- 2.4 MUm; P < 0.001). This is the first study to directly compare OCTA against histology from the same human eye. OCTA visualizes many of the vascular structures in the human retinal circulation but does not exactly match what is seen on histologic examination.

AB - Estrogens modulate the immune system and possess anti-inflammatory properties. In line, immune cells express a variety of estrogen receptors (ER) including ER alpha and -beta. In the present study, we examined the influence of 17beta estradiol (E2) serum concentrations on blood leukocyte composition and their ex vivo polarization/activation status by FACS analysis in sub-fertile human females under controlled ovarian stimulation (COS). Using a set of cell-type and polarization-specific markers, we demonstrate that increased 17beta-estradiol (E2) serum concentrations yield an overall increase in leukocytes, neutrophils and monocytes but decreased lymphocytes. There was a clear ratio shift towards an increase in M2 monocytes with a protective quality and an increase in T-helper cells compared to a decrease in cytotoxic T-cells. These data support experimental findings and clinical trials, i.e. related to multiple sclerosis and other autoimmune-related diseases, that have shown a down-regulation of CD8(+) T cells and up-regulation of T-regulatory cells. Further studies have to pinpoint to which extent the immune system/-responsiveness of otherwise healthy female patients is affected by medium-term systemic E2 variations. PMID- 29448044 TI - Safety evaluation of a human chimeric monoclonal antibody that recognizes the extracellular loop domain of claudin-2. AB - Claudin-2 (CLDN-2), a pore-forming tight junction protein with a tetra transmembrane domain, is involved in carcinogenesis and the metastasis of some cancers. Although CLDN-2 is highly expressed in the tight junctions of the liver and kidney, whether CLDN-2 is a safe target for cancer therapy remains unknown. We recently generated a rat monoclonal antibody (mAb, clone 1A2) that recognizes the extracellular domains of human and mouse CLDN-2. Here, we investigated the safety of CLDN-2-targeted cancer therapy by using 1A2 as a model therapeutic antibody. Because most human therapeutic mAbs are IgG1 subtype that can induce antibody-dependent cellular cytotoxicity, we generated a human-rat chimeric IgG1 form of 1A2 (xi-1A2). xi-1A2 activated Fcgamma receptor IIIa in the presence of CLDN-2-expressing cells, indicating that xi-1A2 likely exerts antibody-dependent cellular cytotoxicity. At 24 h after its intravenous injection, xi-1A2 was distributed into the liver, kidney, and tumor tissues of mice bearing CLDN-2 expressing fibrosarcoma cells. Treatment of the xenografted mice with xi-1A2 attenuated tumor growth without apparent adverse effects, such as changes in body weight and biochemical markers of liver and kidney injury. These results support xi-1A2 as the lead candidate mAb for safe CLDN-2-targeted cancer therapy. PMID- 29448046 TI - Diurnal variation in admission troponin concentrations in patients with chest pain in the emergency department. AB - BACKGROUND: Recent studies have suggested that there may be large diurnal variation in cardiac troponin T (cTnT) concentrations measured with a high sensitive assay. OBJECTIVE: To investigate if clinically relevant diurnal variation in cTnT concentrations is present in patients with chest pain in the emergency department (ED). METHODS: We included all patients with chest pain, but no myocardial infarction (MI), and no other acute condition that may affect troponin concentrations in the ED at Karolinska University Hospital, Stockholm, Sweden, 2011-2014. Time periods for blood sampling were: 00.00-03.59 am, 04.00 07.59 am, 08.00-11.59 am, 00.00-03.59 pm, 04.00-07.59 pm, and 08.00-11.59 pm. Negative binomial regression models were used to calculate least-square means of admission cTnT concentrations with 95% confidence intervals (CIs). RESULTS: A total of 19,460 patients were included with a mean age of 54 +/- 16 years. Patients who arrived during the night were younger, but other characteristics were similar among the time periods. The greatest mean admission cTnT concentrations for men (9.0 ng/l, 95% CI, 8.7-9.3), and women (8.0 ng/l, 95% CI, 7.8-8.2) were found at 08.00-11.59 am. After adjustment for age and estimated glomerular filtration rate, no significant diurnal variation in admission cTnT concentrations was observed. CONCLUSIONS: In a cohort of unselected patients with chest pain, and no acute condition affecting troponin admission concentrations, we found no evidence of clinically relevant diurnal variation in admission cTnT concentrations. There is no need to take the time point when blood is drawn into account in the assessment of admission cTnT concentrations in the ED. PMID- 29448047 TI - Genital lubrication: A cue-specific sexual response? AB - Women's genital responses are sensitive to the presence and intensity of sexual cues, yet some stimulus features (e.g., male vs. female actors, consensual vs. non-consensual interactions) have little influence on the magnitude of response-a phenomenon called low cue-specificity. Genital responses are typically assessed using vaginal photoplethysmography, a measure of vaginal vasocongestion, itself a precursor to lubrication. One explanation for low cue-specificity is the preparation hypothesis: Women genitally respond to almost all sexual cues because lubrication functions to protect genital organs from potential injury should vaginal penetration occur. In order to test the preparation hypothesis, both vaginal vasocongestion and introital lubrication were assessed in a sample of 20 women in response to sexually explicit films. While patterns of vasocongestion were consistent with low cue-specificity for gender cues and type of sexual activity, lubrication was specific to women's most preferred sexual stimulus categories. These results are inconsistent with the preparation hypothesis. PMID- 29448045 TI - Serum ARCHITECT PIVKA-II reference interval in healthy Chinese adults: Sub analysis from a prospective multicenter study. AB - BACKGROUND: Protein induced by vitamin K absence or antagonist-II (PIVKA-II) has been widely used as a biomarker for liver cancer diagnosis in Japan for decades. However, the reference intervals for serum ARCHITECT PIVKA-II have not been established in the Chinese population. Thus, this study aimed to measure serum PIVKA-II levels in healthy Chinese subjects. METHODS: This is a sub-analysis from the prospective, cross-sectional and multicenter study (ClinicalTrials.gov Identifier: NCT03047603). A total of 892 healthy participants (777 Han and 115 Uygur) with complete health checkup results were recruited from 7 regional centers in China. Serum PIVKA-II level was measured by ARCHITECT immunoassay. All 95% reference ranges were estimated by nonparametric method. RESULTS: The distribution of PIVKA-II values showed significant difference with ethnicity and sex, but not age. The 95% reference range of PIVKA-II was 13.62-40.38 mAU/ml in Han Chinese subjects and 15.16-53.74 mAU/ml in Uygur subjects. PIVKA-II level was significantly higher in males than in females (P < 0.001). The 95% reference range of PIVKA-II was 15.39-42.01 mAU/ml in Han males while 11.96-39.13 mAU/ml in Han females. CONCLUSIONS: The reference interval of serum PIVKA-II on the Architect platform was established in healthy Chinese adults. This will be valuable for future clinical and laboratory studies performed using the Architect analyzer. Different ethnic backgrounds and analytical methods underline the need for redefining the reference interval of analytes such as PIVKA-II, in central laboratories in different countries. PMID- 29448048 TI - Scholarly Activity Training During Residency: Are We Hitting the Mark? A National Assessment of Pediatric Residents. AB - OBJECTIVE: Participation in scholarly activity (SA) is an Accreditation Council for Graduate Medical Education requirement. Our previous research with program directors (PDs) suggests that pediatric SA training is variable and suboptimal. To help programs better meet requirements, our objective was to understand the resident perspective regarding SA training, including factors associated with satisfaction and productivity. METHODS: We conducted cross-sectional surveys of second- and third-year pediatric residents and PDs at 22 diverse programs in 2016. Surveys assessed resident demographics, career intentions, program characteristics, beliefs, barriers, satisfaction, and productivity, defined as SA accepted at a regional or national meeting, for publication, or grant funding. Data were analyzed using descriptive statistics and multivariable logistic regression. RESULTS: A total of 464 (60.2%) of 771 residents and 22 PDs (100%) responded. Most residents believed that residents should participate in SA (n = 380, 81.9%). However, only 37.9% (n = 175) were extremely or very satisfied with their training. Residents who reported that training to conduct research (adjusted odds ratio [AOR] = 1.9, 95% confidence interval [CI] 1.1-3.5), availability of a research curriculum (AOR = 1.9, 95% CI 1.2-3.1), and adequate faculty mentorship (AOR = 2.5, 95% CI 1.6-4.1) were not barriers were more satisfied. Protected time was associated with satisfaction (AOR = 1.7, 95% CI 1.1 2.7). A total of 43.8% of residents (n = 203) were productive. Productivity was associated with future plans to conduct research (AOR = 3.3, 95% CI 2.1-5.1). CONCLUSIONS: Residents believe SA training is important. Dedicated program infrastructure, protected time, and adequate mentorship appear to be crucial to improving quality perceptions.

AB - High temperature crystal elasticity constants for face centred cubic austenite are important for interpreting the ultrasonic properties of iron and steels but cannot be determined by normal single crystal methods. Values of these constants have recently been calculated using an ab-initio approach and the present work was carried out to test their applicability using laser-ultrasonic measurements. Steel samples having a known texture were examined at temperatures between 800 degrees C and 1100 degrees C to measure the velocity of longitudinal P-waves which were found to be in good agreement with modelled values.

AB - In order to investigate killer immunoglobulin-like receptors (KIR) and their ligands, human leukocyte antigen (HLA), diversity in the Brazilian population influenced by migrations, unrelated Brazilian Japanese descendants were selected and genotyped for the KIR genes and HLA class I allele groups. Genetic heterogeneity in Brazil Parana Japanese was observed for KIR genes, whose frequency distributions demonstrated similarity with mixed Brazilian populations and with the Japanese population, suggesting gene flow. The data contributed to the identification of the genetic constitution of the Brazilian population influenced by immigrations and two new genotypes were defined. PMID- 29448053 TI - Biomarkers of operational tolerance following kidney transplantation - The immune tolerance network studies of spontaneously tolerant kidney transplant recipients. AB - Studies of kidney transplant recipients who have developed spontaneous and sustained tolerance have revealed an association with B cells. Unexpectedly tolerant individuals are characterized by increased numbers and frequencies of B cells in the blood and increased expression of genes associated with B cells in the blood and urine. Comparisons of the B cell repertoires of tolerant individuals and those receiving immunosuppression reveal that not only are the B cells more numerous but developmental differences result in a repertoire comprised of more naive and transitional B cells in the tolerant cohort. B cells isolated from tolerant individuals also display functional differences compared to those from individuals receiving immunosuppression. Many of these differences may serve to suppress alloimmunity. Lastly a significant number of transplant recipients receiving standard immunosuppression display B cell-biased patterns of gene expression predictive of tolerance or a pro-tolerogenic state. Interestingly, this pattern is associated with improved renal allograft function. While recent studies have raised the concern that immunosuppressive drugs heavily influence B cell-based "signatures of tolerance", a substantial body of work suggests that differences in B cells may be a useful tool for identifying tolerant kidney transplant recipients or guiding their immunosuppressive management. PMID- 29448054 TI - RAGE-induced changes in the proteome of alveolar epithelial cells. AB - : The receptor for advanced glycation end-products (RAGE) is a pattern recognition receptor and member of the immunoglobulin superfamily. RAGE is constitutively expressed in the distal lung where it co-localizes with the alveolar epithelium; RAGE expression is otherwise minimal or absent, except with disease. This suggests RAGE plays a role in lung physiology and pathology. We used proteomics to identify and characterize the effects of RAGE on rat alveolar epithelial (R3/1) cells. LC-MS/MS identified 177 differentially expressed proteins and the PANTHER Classification System further segregated proteins. Proteins involved in gene transcription (RNA and mRNA splicing, mRNA processing) and transport (protein, intracellular protein) were overrepresented; genes involved in a response to stimulus were underrepresented. Immune system processes and response to stimuli were downregulated with RAGE knockdown. Western blot confirmed RAGE-dependent changes in protein expression for NFkappaB and NLRP3 that was functionally supported by a reduction in IL-1beta and phosphorylated p65. We also assessed RAGE's effect on redox regulation and report that RAGE knockdown attenuated oxidant production, decreased protein oxidation, and increased reduced thiol pools. Collectively the data suggest that RAGE is a critical regulator of epithelial cell response and has implications for our understanding of lung disease, specifically acute lung injury. SIGNIFICANCE STATEMENT: In the present study, we undertook the first proteomic evaluation of RAGE-dependent processes in alveolar epithelial cells. The alveolar epithelium is a primary target during acute lung injury, and our data support a role for RAGE in gene transcription, protein transport, and response to stimuli. More over our data suggest that RAGE is a critical driver of redox regulation in the alveolar epithelium. The conclusions of the present work assist to unravel the molecular events that underlie the function of RAGE in alveolar epithelial cells and have implications for our understanding of RAGE signaling during lung injury. Our study was the first proteomic comparison showing the effects of RAGE activation from alveolar epithelial cells that constitutively express RAGE and these results can affect a wide field of lung biology, pulmonary therapeutics, and proteomics. PMID- 29448055 TI - Proteomic characterization of Withaferin A-targeted protein networks for the treatment of monoclonal myeloma gammopathies. AB - : Withaferin A (WA), a natural steroid lactone from the plant Withania somnifera, is often studied because of its antitumor properties. Although many in vitro and in vivo studies have been performed, the identification of Withaferin A protein targets and its mechanism of antitumor action remain incomplete. We used quantitative chemoproteomics and differential protein expression analysis to characterize the WA antitumor effects on a multiple myeloma cell model. Identified relevant targets were further validated by Ingenuity Pathway Analysis and Western blot and indicate that WA targets protein networks that are specific for monoclonal gammopathy of undetermined significance (MGUS) and other closely related disorders, such as multiple myeloma (MM) and Waldenstrom macroglobulinemia (WM). By blocking the PSMB10 proteasome subunit, downregulation of ANXA4, potential association with HDAC6 and upregulation of HMOX1, WA puts a massive blockage on both proteotoxic and oxidative stress responses pathways, leaving cancer cells defenseless against WA induced stresses. These results indicate that WA mediated apoptosis is preceded by simultaneous targeting of cellular stress response pathways like proteasome degradation, autophagy and unfolded protein stress response and thus suggests that WA can be used as an effective treatment for MGUS and other closely related disorders. SIGNIFICANCE: Multifunctional antitumor compounds are of great potential since they reduce the risk of multidrug resistance in chemotherapy. Unfortunately, characterization of all protein targets of a multifunctional compound is lacking. Therefore, we optimized an SILAC quantitative chemoproteomics workflow to identify the potential protein targets of Withaferin A (WA), a natural multifunctional compound with promising antitumor properties. To further understand the antitumor mechanisms of WA, we performed a differential protein expression analysis and combined the altered expression data with chemoproteome WA target data in the highly curated Ingenuity Pathway database. We provide a first global overview on how WA kills multiple myeloma cancer cells and serve as a starting point for further in depth experiments. Furthermore, the combined approach can be used for other types of cancer and/or other promising multifunctional compounds, thereby increasing the potential development of new antitumor therapies. PMID- 29448056 TI - Proteomic analysis of first trimester maternal serum to identify candidate biomarkers potentially predictive of spontaneous preterm birth. AB - : Spontaneous preterm birth (sPTB) remains a major clinical dilemma; current diagnostics and interventions have not reduced the rate of this serious healthcare burden. This study characterizes differential protein profiles and post-translational modifications (PTMs) in first trimester maternal serum using a refined top-down approach coupling two-dimensional gel electrophoresis (2DE) and mass spectrometry (MS) to directly compare subsequent term and preterm labour events and identify marked protein differences. 30 proteoforms were found to be significantly increased or decreased in the sPTB group including 9 phosphoproteins and 11 glycoproteins. Changes occurred in proteins associated with immune and defence responses. We identified protein species that are associated with several clinically relevant biological processes, including interrelated biological networks linked to regulation of the complement cascade and coagulation pathways, immune modulation, metabolic processes and cell signalling. The finding of altered proteoforms in maternal serum from pregnancies that delivered preterm suggests these as potential early biomarkers of sPTB and also possible mediators of the disorder. BIOLOGICAL SIGNIFICANCE: Identifying changes in protein profiles is critical in the study of cell biology, and disease treatment and prevention. Identifying consistent changes in the maternal serum proteome during early pregnancy, including specific protein PTMs (e.g. phosphorylation, glycosylation), is likely to provide better opportunities for prediction, intervention and prevention of preterm birth. This is the first study to examine first trimester maternal serum using a highly refined top-down proteomic analytical approach based on high resolution 2DE coupled with mass spectrometry to directly compare preterm (<37 weeks) and preterm (>=37 weeks) events and identify select protein differences between these conditions. As such, the data present a promising avenue for translation of biomarker discovery to a clinical setting as well as for future investigation of underlying aetiological processes. PMID- 29448057 TI - HLA-Matched Sibling versus Unrelated versus Haploidentical Related Donor Allogeneic Hematopoietic Stem Cell Transplantation for Patients Aged Over 60 Years with Acute Myeloid Leukemia: A Single-Center Donor Comparison. AB - Haploidentical related donor (HRD) allogeneic hematopoietic stem cell transplantation (allo-HSCT) was developed as a valid option for the treatment of acute myeloid leukemia (AML) in the absence of a matched donor. However, many investigators are reluctant to consider the use of this alternative in elderly patients, anticipating high morbidity. Here, we report a single-center comparison of HRD versus matched sibling donor (MSD) and unrelated donor (UD) allo-HSCT for patients with AML aged >=60 years. Ninety-four patients (MSD: n = 31; UD: n = 30; HRD: n = 33) were analyzed. The median age was 65 (range, 60 to 73) years. We observed a higher cumulative incidence of grade 3 to 4 acute graft-versus-host disease (GVHD) after UD allo-HSCT (MSD versus UD versus HRD: 3% versus 33% versus 6%, respectively; P = .006). Two-year cumulative incidence of moderate or severe chronic GVHD was 17%, 27%, and 16% in the MSD, UD, and HRD groups, respectively (P = .487). No difference was observed in the 2-year cumulative incidence of relapse or nonrelapse mortality (NRM) (relapse: MSD versus UD versus HRD: 32% versus 25% versus 25%, respectively; P = .411; NRM: MSD versus UD versus HRD: 19% versus 27% versus 24%, respectively; P = .709). At 2 years, progression-free survival, overall survival, and GVHD- and relapse-free survival were 48%, 50%, and 39%, respectively, in the MSD group; 48%, 51%, and 23%, respectively, in the UD group; and 50%, 52%, and 32%, respectively, in the HRD group, without statistically significant differences between the groups. We conclude that HRD allo-HSCT is highly feasible and no less efficient than MSD or UD allo-HSCT in patients with AML aged >=60 years. Thus, the absence of a HLA-identical donor should not limit the consideration of allo-HSCT for the treatment of AML. PMID- 29448058 TI - Early Post-Transplant Minimal Residual Disease Assessment Improves Risk Stratification in Acute Myeloid Leukemia. AB - We studied if the inclusion of early post-stem cell transplantation (SCT) minimal residual disease (MRD) assessments improved prognostication in patients with acute myeloid leukemia (AML). Two hundred sixty-nine AML patients in morphological complete remission (CR) who underwent a first SCT were included if they had evaluable pre-SCT MRD assessment by multiparametric flow cytometry. Post SCT MRD assessments were performed at days +30, +100, and +180. The primary outcome was 1-year relapse incidence (RI). Of 269 patients in CR, 83 (30.8%) had detectable MRD pre-SCT. Post-SCT, during routine disease assessment time points, 9 of 241 evaluable patients (3.7%) at day +30, 6 of 191 evaluable patients (3.1%) at day +100, and 4 of 133 evaluable patients (3%) at day +180 were MRD positive while in CR. MRD positivity at day +30 predicted the highest risk of relapse at 1 year (group 1, 1-year RI 78%). Among MRD-negative patients at day +30, either adverse risk category by European Leukemia Net (ELN) or intermediate risk who were aged >=60 years and/or pre-SCT MRD-positive represented the intermediate risk group (group 2, 1-year RI 29%). The remaining patients represented the low risk group (group 3, 1-year RI 5%). For patients in CR beyond day +30 post-SCT, detectable MRD at any time point predicted impending relapse within 2 months. Early post-SCT MRD assessment-combined with pre-SCT MRD assessment, ELN risk category, and age-improves risk stratification for relapse in AML patients post transplant. Studies aimed at preventing impending relapse in this high-risk population are urgently needed. PMID- 29448059 TI - Monte Carlo simulation of the relative biological effectiveness and DNA damage from a 400 MeV/u carbon ion beam in water. AB - A 400 MeV/u carbon ion beam incident on a water phantom was simulated with GATE/Geant4 to calculate the energy spectra of 12C and its fragments at various depths. Based on the energy spectra, the DNA double strand break (DSB) yields from 12C and its fragments were calculated with Monte Carlo Damage Simulation (MCDS) code. The relative biological effectiveness (RBE) distributions for 12C and its fragments were calculated from the DSB yields. The DNA damages from each type of the particles and their contribution to the total DNA damages at various depths were calculated from the DSB yields and dose distributions. These characteristics of 12C and its fragments are important for understanding the corresponding RBEs and the DNA damages. The purpose of this work was to obtain the RBEs and the DNA damage distributions of carbon ions and their fragments in beams used in radiotherapy by means of simulating the macroscopic phantom and microscopic cells. The simulation method can be easily extended by changing some parameters. PMID- 29448060 TI - A rapid method for the sequential separation of polonium, plutonium, americium and uranium in drinking water. AB - A new sequential separation method for the determination of polonium and actinides (Pu, Am and U) in drinking water samples has been developed that can be used for emergency response or routine water analyses. For the first time, the application of TEVA chromatography column in the sequential separation of polonium and plutonium has been studied. This method utilizes a rapid Fe+3 co precipitation step to remove matrix interferences, followed by plutonium oxidation state adjustment to Pu4+ and an incubation period of ~ 1 h at 50-60 degrees C to allow Po2+ to oxidize to Po4+. The polonium and plutonium were then separated on a TEVA column, while separation of americium from uranium was performed on a TRU column. After separation, polonium was micro-precipitated with copper sulfide (CuS), while actinides were micro co-precipitated using neodymium fluoride (NdF3) for counting by the alpha spectrometry. The method is simple, robust and can be performed quickly with excellent removal of interferences, high chemical recovery and very good alpha peak resolution. The efficiency and reliability of the procedures were tested by using spiked samples. The effect of several transition metals (Cu2+, Pb2+, Fe3+, Fe2+, and Ni2+) on the performance of this method were also assessed to evaluate the potential matrix effects. Studies indicate that presence of up to 25 mg of these cations in the samples had no adverse effect on the recovery or the resolution of polonium alpha peaks. PMID- 29448061 TI - Allocation rules for global donors. AB - In recent years, donors such as the Bill and Melinda Gates Foundation have made an enormous contribution to the reduction of the global burden of disease. It has been argued that such donors should prioritise interventions based on their cost effectiveness, that is to say, the ratio of costs to benefits. Against this, we argue that the donor should fund not the most cost-effective interventions, but rather interventions which are just cost-ineffective for the country, thus encouraging the country to contribute its own domestic resources to the fight against disease. We demonstrate that our proposed algorithm can be justified within the context of a model of the problem as a leader-follower game, in which a donor chooses to subsidise interventions which are implemented by a country. We argue that the decision rule we propose provides a basis for the allocation of aid money which is efficient, fair and sustainable. PMID- 29448062 TI - Geological data indicate that the interpretation for the age-calibrated phylogeny for the Kurixalus-genus frogs of South, South-east and East Asia (Lv et al., 2018) needs to be rethought. AB - Recently, Lv et al. (2018) published an age-calibrated phylogenetic tree for the Kurixalus frogs, members of which occur across parts of South, South-east and East Asia. A clade on Taiwan, represented by Kurixalus idiootocus and the Kurixalus eiffingeri species complex, is deemed to have been resident since the middle Cenozoic; its closest congeners are in southern Indochina (not in the adjacent parts of south-east China), and the split between the two is dated at 32.8 Ma. Furthermore, a sub-population of Kurixalus eiffingeri is believed to have colonized islands in the western Ryukyus c. 13.5 Ma. There is, however, a problem with this scenario: the landmass regarded as modern-day Taiwan has existed only for 4-5 million years (it results from a young and ongoing tectonic plate collision). Assuming the Kurixalus phylogeny and the dating of its branchings are correct, then a palaeobiogeographical scenario involving an older, alternative land surface with later transfer to Taiwan, possibly involving over water dispersal, would reconcile the biology, but testing this may be difficult/impossible. If the ages of the nodes in the proposed tree are found to be significantly overestimated, the geology and biology might more easily be accommodated. PMID- 29448063 TI - An ant genus-group (Prenolepis) illuminates the biogeography and drivers of insect diversification in the Indo-Pacific. AB - The Malay Archipelago and the tropical South Pacific (hereafter the Indo-Pacific region) are considered biodiversity hotspots, yet a general understanding of the origins and diversification of species-rich groups in the region remains elusive. We aimed to test hypotheses for the evolutionary processes driving insect species diversity in the Indo-Pacific using a higher-level and comprehensive phylogenetic hypothesis for an ant clade consisting of seven genera. We estimated divergence times and reconstructed the biogeographical history of ant species in the Prenolepis genus-group (Formicidae: Formicinae: Lasiini). We used a fossil calibrated phylogeny to infer ancestral geographical ranges utilizing a biogeographic model that includes founder-event speciation. Ancestral state reconstructions of the ants' ecological preferences, and diversification rates were estimated for selected Indo-Pacific clades. Overall, we report that faunal interchange between Asia and Australia has occurred since at least 20-25 Ma, and early dispersal to the Fijian Basin happened during the early and mid-Miocene (ca. 10-20 Ma). Differences in diversification rates across Indo-Pacific clades may be related to ecological preference breadth, which in turn may have facilitated geographical range expansions. Ancient dispersal routes suggested by our results agree with the palaeogeography of the region. For this particular group of ants, the rapid orogenesis in New Guinea and possibly subsequent ecological shifts may have promoted their rapid diversification and widespread distribution across the Indo-Pacific.

AB - The Culex quinquefasciatus mosquito is a vector of several diseases, and its control has been performed with synthetic insecticides, which may have human and environmental side effects. Thus, the use of new and safe molecules are important, and this study evaluated the toxicity of active substances against this mosquito. The oleic, linoleic, linolenic, palmitic and stearic acids and their respective methyl esters were tested against fourth instar C. quinquefasciatus larvae. Oleic, linoleic and linolenic acids had LC50 values of 8.58, 10.04 and 19.78 mg/L, respectively. Histological analysis showed that these three compounds caused cell instability with an increase in the number of vesicles in the fat body and in the midgut cells. Based on these results, glucose, triglyceride, and protein levels were evaluated after 1 h of acid exposure. These compounds decreased in insects treated with linoleic acid. Linolenic acid also caused a significant increase in acetylcholinesterase activity. These results show that oleic, linoleic, and linoleic acids have a lower LC50 for C. quinquefasciatus, affecting its metabolism and the morphology of midgut and fat body.

AB - OBJECTIVE: There has been a growing recognition that obstructive sleep apnea (OSA) could increase the propensity for type 2 diabetes the metabolic syndrome. However, studies concerning about the impact of non-apnea sleep disorders (NSD) on diabetes control and metabolic outcomes are relatively scarce. Our aim is to investigate the impact of non-apnea sleep disorders (NSD) on diabetic control and associated metabolic outcomes in patients with type 2 diabetes. METHODS: The data were obtained from two nationwide population-based databases for a period 2007 to 2012. A total 66,992 patients with type 2 diabetes were enrolled and divided into two cohorts based on comorbidity with or without a NSD diagnosis, and were followed up four years. The primary outcomes were to compare rate of change in HbA1c and associated metabolic outcomes during follow-up visits between patients with or without NSD. The secondary outcome is to examine whether NSD were associated with poor glycemic control of the last clinical records while controlling for the baseline HbA1c value. RESULTS: Of the 66,992 patients with type 2 diabetes, 14.82% had comorbidity with a NSD. HbA1C decreases were significantly lower by 0.04% in the NSD group (P < 0.05), and triglyceride (TG) decreases remained significantly lower by 2.53% in the NSD group (P < 0.05). Furthermore, patients in the NSD group had an 8% higher risk of poor glycemic control (HbA1C >9) (OR = 1.08; 95%CI, 1.01-1.16). CONCLUSION: Our findings indicated patients with type 2 diabetes comorbid with NSD had a slower improvement in HbA1c compared with the comparison cohort. It may because there may exist potential floor effect given those with NSD having significantly lower HbA1c values at baseline. On the other hand, the poor diabetic control among those with NSD may be also affected by other confounders such as medical treatment or interventions. Nevertheless, given the rapidly increasing prevalence of metabolic diseases and subsequent complications, the results may highlight the importance of sleep in the clinical management of type 2 diabetes.

AB - A new set of applications can be achieved when using high stability proteases. Industrially, high costs can be related to production medium and purification process. Magnetic nanoparticles have been successfully used for rapid and scalable purification. In this work, azocasein were immobilized on magnetite nanoparticles and applied in a single step purification of protease produced by Penicillium aurantiogriseum using soybean flour medium, and the new purified enzyme was characterized. Glutaraldehyde activated nanoparticles were used in azocasein immobilization and then incubated with dialyzed 60-80% saline precipitation fraction of crude extract for purification. Adsorbents were washed 7 times (0.1 M NaCl solution) and eluted 3 times (1 M NaCl solution), these final elutions contained the purified protease. This protease was purified 55.68-fold, retaining 46% of its original activity. Presented approximately 40 kDa on SDS PAGE and optimum activity at 45 degrees C and pH 9.0. Maintained over 60% of activity from pH 6.0 to 11.0. Kept more than 50% activity from 15 to 55 degrees C, did not lose any activity over 48 h at 25 degrees C. Inhibitors assay suggested a serine protease with aspartic residues on its active site. Results report a successful application of an alternative purification method and novel broad pH tolerant protease. PMID- 29448067 TI - Antiviral resistance due to deletion in the neuraminidase gene and defective interfering-like viral polymerase basic 2 RNA of influenza A virus subtype H3N2. AB - BACKGROUND AND OBJECTIVE: Antiviral treatment of influenza virus infections can lead to drug resistance of virus. This study investigates a selection of mutations in the full genome of H3N2 influenza A virus isolated from a patient in treatment with oseltamivir. STUDY DESIGN: Respiratory samples from a patient were collected before, during, and after antiviral treatment. Whole genome sequencing of the influenza virus by next generation sequencing, and low-frequency-variant analysis was performed. Neuraminidase-inhibition tests were performed with oseltamivir and zanamivir, and viruses were propagated in sial-transferase gene transfected Madin-Darby Canine Kidney cells. RESULTS: A deletion at amino acid position 245-248 in the neuraminidase gene occurred after initiation of treatment with oseltamivir. The deleted virus had highly reduced inhibition against oseltamivir but was sensitive to zanamivir. Nine days after discontinuation of oseltamivir treatment the deleted H3N2 virus was still present in the patient. After three passages of the deleted virus in cell culture, the deletion was retained. Several variant mutations appeared in the other genes of the H3N2 virus, where most striking were two major out-of-frame deletions in the polymerase basic 2 (PB2) gene, indicating defective interfering-like viral RNA. CONCLUSIONS: The viruses harboring the 245-248 deletion in the neuraminidase gene were still present after discontinuation of oseltamivir treatment and passages in cell cultures, indicating a potential risk for transmission of the deleted virus. Full genome deep sequencing was useful to reveal variant mutations that might be selected due to antiviral treatment, and defective interfering-like viral PB2 RNA in the respiratory samples was detected. PMID- 29448068 TI - Systems immunology allows a new view on human dendritic cells. AB - As the most important antigen-presenting cells, dendritic cells connect the innate and adaptive part of our immune system and play a pivotal role in our course of action against invading pathogens as well as during successful vaccination. Immunologists have therefore studied these cells in great detail using flow cytometry-based analyses, in vitro assays and in vivo models, both in murine models and in humans. Albeit, sophisticated, classical immunological, and molecular approaches were often unable to unequivocally determine the subpopulation structure of the dendritic cell lineage and not surprisingly, conflicting results about dendritic cell subsets co-existed throughout the last decades. With the advent of systems approaches and the most recent introduction of -omics approaches on the single cell level combined with multi-colour flow cytometry or mass cytometry, we now enter an era allowing us to define cell population structures with an unprecedented precision. We will report here on the most recent studies applying these technologies to human dendritic cells. Proper delineation of and definition of molecular signatures for the different human dendritic cell subsets will greatly facilitate studying these cells in the future: understanding their function under physiological as well as pathological conditions. PMID- 29448069 TI - Micro-environmental signals directing human epidermal Langerhans cell differentiation. AB - Human Langerhans cells (LC) can be generated ex vivo from hematopoietic precursor cells in response to cytokines and cell-membrane associated ligands. These in vitro differentiation models provided mechanistic insights into the molecular and cellular pathways underlying the development of this unique, epithelia-associated dendritic cell subset. Notably, the human epidermal microenvironment is fully sufficient to induce LC differentiation from hematopoietic progenitors. Hence, dissecting the molecular characteristics of the human epithelial/epidermal LC niche, and testing defined ligands for their capacity to induce LC differentiation, led to a refined molecular model of LC lineage commitment. During epidermal ontogeny, spatially and temporally regulated availability of TGF beta family members cooperate with other keratinocyte-derived signals, such as E cadherin and Notch ligands, for instructing LC differentiation. In this review, we discuss the signals known to instruct human hematopoietic progenitor cells and myelomonocytic cells to undergo LC lineage commitment. Additionally, the current methods for generation of large numbers of human LC-like cells ex vivo in defined serum-free media are discussed. PMID- 29448070 TI - Human in vivo-differentiated monocyte-derived dendritic cells. AB - When entering tissues, monocytes can differentiate into cells that share morphological and functional features with either dendritic cells (DC) or macrophages. Monocyte-derived DC have been observed in humans at mucosal tissues and in inflammatory settings, where they are usually referred to as "inflammatory DC". In this chapter, we review recent studies on the characterization of these cells in humans. We also discuss nomenclature and examine the criteria defining in vivo-differentiated human mo-DC. PMID- 29448071 TI - Activating embryonic development in Drosophila. AB - The transition from oocyte to embryo marks the onset of development. This process requires complex regulation to link developmental signals with profound changes in mRNA translation, cell cycle control, and metabolism. This control is beginning to be understood for most organisms, and research in the fruit fly Drosophila melanogaster has generated new insights. Recent findings have increased our understanding of the roles played by hormone and Ca2+ signaling events as well as metabolic remodeling crucial for this transition. Specialized features of the structure and assembly of the meiotic spindle have been identified. The changes in protein levels, mRNA translation, and polyadenylation that occur as the oocyte becomes an embryo have been identified together with key aspects of their regulation. Here we highlight these important developments and the insights they provide on the intricate regulation of this dramatic transition.

AB - BACKGROUND: The equivalent efficacy between SB3, a proposed trastuzumab biosimilar, and the trastuzumab reference product (TRZ) in terms of the breast pathologic complete response rate after neoadjuvant therapy in patients with early or locally advanced human epidermal growth factor receptor 2-positive breast cancer was demonstrated in the previous report. Here, we report the final safety, immunogenicity and survival results after neoadjuvant-adjuvant treatment. PATIENTS AND METHODS: Patients were randomised 1:1 to receive neoadjuvant SB3 or TRZ for 8 cycles concurrently with chemotherapy (4 cycles of docetaxel followed by 4 cycles of 5-fluorouracil/epirubicin/cyclophosphamide). Patients then underwent surgery, followed by 10 cycles of adjuvant SB3 or TRZ as randomised. End-points included safety, immunogenicity, event-free survival (EFS) and overall survival through the adjuvant period. RESULTS: Of 875 patients randomised, 764 (SB3, n = 380; TRZ, n = 384) completed the study. The median follow-up duration was 437 days in the SB3 group and 438 days in the TRZ group. The incidence of treatment-emergent adverse events was comparable between groups (SB3, 97.5%; TRZ, 96.1%) during the overall study period. Up to the end of study, the overall incidence of antidrug antibody was low in both treatment groups (3 patients each). EFS was comparable between groups with a hazard ratio (SB3/TRZ) of 0.94 (95% confidence interval, 0.59-1.51) and EFS rates at 12 months of 93.7% for SB3 and 93.4% for TRZ. CONCLUSIONS: Final safety, immunogenicity and survival results of this study further support the biosimilarity established between SB3 and TRZ.

AB - We present distinct patterns of neurite distribution in the human cerebral cortex using diffusion magnetic resonance imaging (MRI). We analyzed both high resolution structural (T1w and T2w images) and diffusion MRI data in 505 subjects from the Human Connectome Project. Neurite distributions were evaluated using the neurite orientation dispersion and density imaging (NODDI) model, optimized for gray matter, and mapped onto the cortical surface using a method weighted towards the cortical mid-thickness to reduce partial volume effects. The estimated neurite density was high in both somatosensory and motor areas, early visual and auditory areas, and middle temporal area (MT), showing a strikingly similar distribution to myelin maps estimated from the T1w/T2w ratio. The estimated neurite orientation dispersion was particularly high in early sensory areas, which are known for dense tangential fibers and are classified as granular cortex by classical anatomists. Spatial gradients of these cortical neurite properties revealed transitions that colocalize with some areal boundaries in a recent multi modal parcellation of the human cerebral cortex, providing mutually supportive evidence. Our findings indicate that analyzing the cortical gray matter neurite morphology using diffusion MRI and NODDI provides valuable information regarding cortical microstructure that is related to but complementary to myeloarchitecture. PMID- 29448074 TI - A probabilistic approach to discovering dynamic full-brain functional connectivity patterns. AB - Recent research shows that the covariance structure of functional magnetic resonance imaging (fMRI) data - commonly described as functional connectivity - can change as a function of the participant's cognitive state (for review see Turk-Browne, 2013). Here we present a Bayesian hierarchical matrix factorization model, termed hierarchical topographic factor analysis (HTFA), for efficiently discovering full-brain networks in large multi-subject neuroimaging datasets. HTFA approximates each subject's network by first re-representing each brain image in terms of the activities of a set of localized nodes, and then computing the covariance of the activity time series of these nodes. The number of nodes, along with their locations, sizes, and activities (over time) are learned from the data. Because the number of nodes is typically substantially smaller than the number of fMRI voxels, HTFA can be orders of magnitude more efficient than traditional voxel-based functional connectivity approaches. In one case study, we show that HTFA recovers the known connectivity patterns underlying a collection of synthetic datasets. In a second case study, we illustrate how HTFA may be used to discover dynamic full-brain activity and connectivity patterns in real fMRI data, collected as participants listened to a story. In a third case study, we carried out a similar series of analyses on fMRI data collected as participants viewed an episode of a television show. In these latter case studies, we found that the HTFA-derived activity and connectivity patterns can be used to reliably decode which moments in the story or show the participants were experiencing. Further, we found that these two classes of patterns contained partially non overlapping information, such that decoders trained on combinations of activity based and dynamic connectivity-based features performed better than decoders trained on activity or connectivity patterns alone. We replicated this latter result with two additional (previously developed) methods for efficiently characterizing full-brain activity and connectivity patterns. PMID- 29448075 TI - Improving mass-univariate analysis of neuroimaging data by modelling important unknown covariates: Application to Epigenome-Wide Association Studies. AB - Statistical inference on neuroimaging data is often conducted using a mass univariate model, equivalent to fitting a linear model at every voxel with a known set of covariates. Due to the large number of linear models, it is challenging to check if the selection of covariates is appropriate and to modify this selection adequately. The use of standard diagnostics, such as residual plotting, is clearly not practical for neuroimaging data. However, the selection of covariates is crucial for linear regression to ensure valid statistical inference. In particular, the mean model of regression needs to be reasonably well specified. Unfortunately, this issue is often overlooked in the field of neuroimaging. This study aims to adopt the existing Confounder Adjusted Testing and Estimation (CATE) approach and to extend it for use with neuroimaging data. We propose a modification of CATE that can yield valid statistical inferences using Principal Component Analysis (PCA) estimators instead of Maximum Likelihood (ML) estimators. We then propose a non-parametric hypothesis testing procedure that can improve upon parametric testing. Monte Carlo simulations show that the modification of CATE allows for more accurate modelling of neuroimaging data and can in turn yield a better control of False Positive Rate (FPR) and Family-Wise Error Rate (FWER). We demonstrate its application to an Epigenome-Wide Association Study (EWAS) on neonatal brain imaging and umbilical cord DNA methylation data obtained as part of a longitudinal cohort study. Software for this CATE study is freely available at http://www.bioeng.nus.edu.sg/cfa/Imaging_Genetics2.html. PMID- 29448076 TI - Single multi-echo GRE acquisition with short and long echo spacing for simultaneous quantitative mapping of fat fraction, B0 inhomogeneity, and susceptibility. AB - Multi-echo gradient echo (mGRE) sequences have been widely adapted in clinical and scientific practice for different purposes to their capability of performing Dixon MRI, generating multi-contrast images and extracting multi-parametric maps. This work aims to extend mGRE-based techniques for imaging whole head, where further technical developments are required due to the co-existence of fat and large B0 inhomogeneity in regions such as the skull base and neck. Specifically, bipolar mGRE data were acquired with a single sequence that contains both a short echo-spacing (DeltaTE) echo train to capture water-fat and B0 phase shifts (for proton density fat-fraction (FF) and B0 mapping) and a longer DeltaTE echo train (and long echo times) to capture subtle susceptibility variations and R2* information. The mGRE images covering the whole head (spatial resolution 1.0 * 1.0 * 2.0 mm3) were acquired in 5 min. An automated processing pipeline was implemented to use the FF and B0 maps determined from the short-TE train to compensate for the effects of fat, remove the background phase for whole-head quantitative susceptibility mapping, and reduce the difficulty of spatial phase unwrapping of the long echo-time data. Data from healthy volunteers imaged on a 3 T scanner along with phantom validation are presented. Co-registered quantitative multi-parametric maps (FF, B0 inhomogeneity, R2*, local frequency shift and quantitative susceptibility) and multi-contrast images covering the whole head were successfully generated in processing times of several minutes. PMID- 29448077 TI - Robust detrending, rereferencing, outlier detection, and inpainting for multichannel data. AB - Electroencephalography (EEG), magnetoencephalography (MEG) and related techniques are prone to glitches, slow drift, steps, etc., that contaminate the data and interfere with the analysis and interpretation. These artifacts are usually addressed in a preprocessing phase that attempts to remove them or minimize their impact. This paper offers a set of useful techniques for this purpose: robust detrending, robust rereferencing, outlier detection, data interpolation (inpainting), step removal, and filter ringing artifact removal. These techniques provide a less wasteful alternative to discarding corrupted trials or channels, and they are relatively immune to artifacts that disrupt alternative approaches such as filtering. Robust detrending allows slow drifts and common mode signals to be factored out while avoiding the deleterious effects of glitches. Robust rereferencing reduces the impact of artifacts on the reference. Inpainting allows corrupt data to be interpolated from intact parts based on the correlation structure estimated over the intact parts. Outlier detection allows the corrupt parts to be identified. Step removal fixes the high-amplitude flux jump artifacts that are common with some MEG systems. Ringing removal allows the ringing response of the antialiasing filter to glitches (steps, pulses) to be suppressed. The performance of the methods is illustrated and evaluated using synthetic data and data from real EEG and MEG systems. These methods, which are mainly automatic and require little tuning, can greatly improve the quality of the data.

AB - Resin glycosides represent an important chemotaxonomic marker of the Convolvulaceae family and possess multidrug resistance (MDR) reversal activity. In our recent study, nine previously undescribed resin glycosides, Calonyctins B J, were isolated from the seeds of Ipomoea muricata. Their structures with the absolute configuration were established on the basis of comprehensive spectroscopic analysis and chemical methods. Among these, Calonyctins F-I possessed a skeleton in which the aglycone moiety and the oligosaccharide core were linked by a 3-hydroxy-2-methylbutanoic acid moiety to form a 25-membered macrocyclic structure. Calonyctins E, J, and muricatic acid C methyl ester were non-cytotoxic but enhanced the cytotoxicity of vincristine by 2.5-407.1 fold at 25 MUM in KB/VCR cells. Calonyctin E was the most active one. PMID- 29448079 TI - Identifying the underlying causes of biological instability in a full-scale drinking water supply system. AB - Changes in bacterial concentration and composition in drinking water during distribution are often attributed to biological (in)stability. Here we assessed temporal biological stability in a full-scale distribution network (DN) supplied with different types of source water: treated and chlorinated surface water and chlorinated groundwater produced at three water treatment plants (WTP). Monitoring was performed weekly during 12 months in two locations in the DN. Flow cytometric total and intact cell concentration (ICC) measurements showed considerable seasonal fluctuations, which were different for two locations. ICC varied between 0.1-3.75 * 105 cells mL-1 and 0.69-4.37 * 105 cells mL-1 at two locations respectively, with ICC increases attributed to temperature-dependent bacterial growth during distribution. Chlorinated water from the different WTP was further analysed with a modified growth potential method, identifying primary and secondary growth limiting compounds. It was observed that bacterial growth in the surface water sample after chlorination was primarily inhibited by phosphorus limitation and secondly by organic carbon limitation, while carbon was limiting in the chlorinated groundwater samples. However, the ratio of available nutrients changed during distribution, and together with disinfection residual decay, this resulted in higher bacterial growth potential detected in the DN than at the WTP. In this study, bacterial growth was found to be higher (i) at higher water temperatures, (ii) in samples with lower chlorine residuals and (iii) in samples with less nutrient (carbon, phosphorus, nitrogen, iron) limitation, while this was significantly different between the samples of different origin. Thus drinking water microbiological quality and biological stability could change during different seasons, and the extent of these changes depends on water temperature, the water source and treatment. Furthermore, differences in primary growth limiting nutrients in different water sources could contribute to biological instability in the network, where mixing occurs. PMID- 29448080 TI - Can breast characteristics predict upper torso musculoskeletal pain? AB - BACKGROUND: Several studies have associated a large breast size with an increased prevalence and severity of musculoskeletal pain, particularly pain in the upper torso. Despite this evidence, no research has explored whether breast size or related characteristics are risk factors for upper torso musculoskeletal pain. METHODS: A backward multiple regression analysis was performed to identify whether characteristics of the breasts and upper torso, as well as physical factors known to be associated with musculoskeletal pain, could predict musculoskeletal pain among a cohort of 378 Australian women aged 18 years and over who had a wide range of breast sizes. FINDINGS: The model identified that breast volume, age and nipple-to-nipple distance predicted 23% of the variance in upper torso musculoskeletal pain reported by the participants. INTERPRETATION: Women with a larger breast volume, lower age and a greater nipple-to-nipple distance were predicted to report a higher upper torso musculoskeletal pain score. PMID- 29448081 TI - Medial tilting of the joint line in posterior stabilized total knee arthroplasty increases contact force and stress. AB - BACKGROUND: Kinematically aligned total knee arthroplasty is based on the concept to represent the premorbid joint alignment with cruciate-retaining implants, characterized by medial tilt and internal rotation. However, kinematic and kinetic effects of kinematically aligned total knee arthroplasty with posterior stabilized implants is unknown. The purpose of this study was to examine the effect of medial tilting of the joint line with posterior-stabilized implants. METHODS: A mechanical alignment model, and medial tilt 3 degrees and 5 degrees models were constructed. Knee kinematics and contact forces were simulated using a musculoskeletal computer simulation model. Contact stresses on the tibiofemoral joint and the post area were then calculated using finite element analysis. FINDINGS: From 0 degrees to 120 degrees of knee flexion, greater external rotation of the femoral component was observed in medial tilt models (-0.6 degrees , 1.8 degrees and 4.2 degrees in mechanical alignment, medial tilt 3 degrees and medial tilt 5 degrees models, respectively). The peak contact stresses on the tibiofemoral joint and the post area at 120 degrees of knee flexion were higher in medial tilt models. The peak contact stresses on the post area in medial tilt 3 degrees and 5 degrees models were 2.2 and 3.8 times greater than that in mechanical alignment model, respectively. INTERPRETATION: Medial tilting of the joint line causes greater axial rotation even with posterior-stabilized implants, which can represent near-normal kinematics. However, medial tilting of the joint line in total knee arthroplasty with posterior-stabilized implants may have a higher risk for polyethylene wear at the tibiofemoral joint and post area, leading to subsequent component loosening. PMID- 29448082 TI - Large enthesophytes in teenage skulls: Mechanical, inflammatory and genetic considerations. AB - BACKGROUND: The literature implies that large enthesophytes are exclusive to genetically predisposed individuals and to Spondyloarthropathies sufferers. Accordingly, the aim of this investigation and report was to assess the involvement of genetic predisposition, inflammatory and/or mechanical influences in the development of large enthesophytes in a sample population of teenagers presenting with large enthesophytes emanating from the external occipital protuberance. METHODS: Analysis was based on four teenage males (13-16 year-old) possessing 14.5-30.5 mm enthesophytes projecting from the external occipital protuberance. This study included assessment of radiographs, MRI scans, blood work, history, the SF-36 health survey, and the comparison of these data with the relevant literature to describe the interrelationships between the presence of enlarged external occipital protuberance, forward head protraction, active inflammation and/or genetic factors. FINDINGS: Known genetic markers (e.g. HLA B27) were not detected by allele-specific primers and both ESR and CRP tests were negative. Additionally, MRI analyses failed to detect active localised inflammation at the external occipital protuberance and surrounding structures. The health survey yielded normal parameters for all participants. All participants displayed significantly large Forward Head Protraction values (>40 mm), and interviews with participants and their parents indicated that concerns related to posture were prevalent since early childhood. INTERPRETATION: This report suggests that mechanical load has an important role in enthesophyte development, irrespective the involvement of inflammatory or genetic factors. PMID- 29448083 TI - Sympathetic arousal, but not disturbed executive functioning, mediates the impairment of cognitive flexibility under stress. AB - Cognitive flexibility emerges from an interplay of multiple cognitive systems, of which lexical-semantic and executive are thought to be the most important. Yet this has not been addressed by previous studies demonstrating that such forms of flexible thought deteriorate under stress. Motivated by these shortcomings, the present study evaluated several candidate mechanisms implied to mediate the impairing effects of stress on flexible thinking. Fifty-seven healthy adults were randomly assigned to psychosocial stress or control condition while assessed for performance on cognitive flexibility, working memory capacity, semantic fluency, and self-reported cognitive interference. Stress response was indicated by changes in skin conductance, hearth rate, and state anxiety. Our analyses showed that acute stress impaired cognitive flexibility via a concomitant increase in sympathetic arousal, while this mediator was positively associated with semantic fluency. Stress also decreased working memory capacity, which was partially mediated by elevated cognitive interference, but neither of these two measures were associated with cognitive flexibility or sympathetic arousal. Following these findings, we conclude that acute stress impairs cognitive flexibility via sympathetic arousal that modulates lexical-semantic and associative processes. In particular, the results indicate that stress-level of sympathetic activation may restrict the accessibility and integration of remote associates and bias the response competition towards prepotent and dominant ideas. Importantly, our results indicate that stress-induced impairments of cognitive flexibility and executive functions are mediated by distinct neurocognitive mechanisms.

AB - In treating head and neck cancer (HNC), the objectives are provided for best functional results and minimal risk of serious complications. The choice of appropriate management depends primarily on specific site and stage of primary tumor at diagnosis. Radiation therapy (RT) with or without concomitant chemotherapy represents a classical treatment option. In this review, we provide an update of recent research strategies to counteract the existing damage caused by RT and highlight clinical trials currently in progress. We discuss the challenges in the evaluation of new stage system and RT-related toxicity onset. We mainly address the deficiencies and the advantages noted in the current treatment era. PMID- 29448086 TI - Exposure to diisodecyl phthalate exacerbated Th2 and Th17-mediated asthma through aggravating oxidative stress and the activation of p38 MAPK. AB - Diisodecyl phthalate (DIDP) is considered to be one of the less toxic phthalates. However epidemiological studies suggest that DIDP is associated with the occurrence of asthma. The effect of DIDP exposure on allergic asthma and the underlying mechanism have not been fully elucidated. Here, mice were exposed to DIDP and sensitization with OVA. The results demonstrated that DIDP exposure aggravated allergic asthma. Exposure to 15 mg/kg/day DIDP markedly exacerbated airway remodeling and promoted airway hyperresponsiveness (AhR). The study suggests that exposure to DIDP not only promotes a predominant Th2 response, but also induces Th17-type immunity. The induced allergic asthma was accompanied by elevation of IgE, an increase in TSLP expression and exacerbation of oxidative stress. Inhibition of oxidative stress by Vitamin E effectively alleviated the airway remodeling and AhR induced by DIDP and OVA sensitization. Treatment with Vitamin E inhibited the Th2 response and the production of TSLP. Blocking the activation of p38 MAPK by SB203580 prevented elevation of IL-1beta and IL-17A induced by DIDP and OVA sensitization and effectively alleviated Th17 type asthmatic lesions. These results suggest that exposure to DIDP exacerbates the Th2 and Th17 response through aggravating oxidative stress and activation of the p38 MAPK pathway. PMID- 29448085 TI - Plk2 Loss Commonly Occurs in Colorectal Carcinomas but not Adenomas: Relationship to mTOR Signaling. AB - Plk2 is a target of p53. Our previous studies demonstrated that with wild-type p53, Plk2 impacts mTOR signaling in the same manner as TSC1, and Plk2-deficient tumors grew larger than control. Other investigators have demonstrated that Plk2 phosphorylates mutant p53 in a positive feedback loop. We investigated Plk2's tumor suppressor functions in relationship to mTOR signaling. Archival specimens from 12 colorectal adenocarcinomas were stained for markers including Plk2, phosphorylated mTOR (serine 2448) and ribosomal S6 (Serine 235/236). We show that Plk2 is expressed in normal colon, with a punctate staining pattern in supranuclear cytoplasm. In colorectal adenocarcinoma, Plk2 demonstrates complete or partial loss of expression. Strong expression of phosphorylated mTOR is observed in the invasive front. Phosphorylated S6 expression partially correlates with phosphorylated mTOR expression but appears more diffuse in some cases. p53 and Ki67 expression is diffuse, in the subset of cases examined. In order to determine whether Plk2 is lost prior to the development of invasive cancer, 8 colon polyps from 6 patients were evaluated for Plk2 expression. All polyps are positive for Plk2. A Cancer Genome Atlas search identified Plk2 mutations to be infrequent in colorectal adenocarcinomas. Neither Plk2 methylation (in the gene body) nor copy number variations correlated with changes in mRNA expression levels. Loss of Plk2 expression along with accentuated expression of phosphorylated mTOR and phosphorylated S6 at the invasive front in some colorectal carcinomas is consistent with previous findings that an interaction between Plk2 and TSC1 / mTOR signaling molecules plays a role in tumor suppression. Plk2 protein expression is lost at the same stage in colorectal carcinogenesis as p53. The p53 dependence of Plk2 loss and tumor suppressor function in relationship to mTOR signaling may have therapeutic implications. PMID- 29448087 TI - Assessment of mitochondrial function following short- and long-term exposure of human bronchial epithelial cells to total particulate matter from a candidate modified-risk tobacco product and reference cigarettes. AB - Mitochondrial dysfunction caused by cigarette smoke is involved in the oxidative stress-induced pathology of airway diseases. Reducing the levels of harmful and potentially harmful constituents by heating rather than combusting tobacco may reduce mitochondrial changes that contribute to oxidative stress and cell damage. We evaluated mitochondrial function and oxidative stress in human bronchial epithelial cells (BEAS 2B) following 1- and 12-week exposures to total particulate matter (TPM) from the aerosol of a candidate modified-risk tobacco product, the Tobacco Heating System 2.2 (THS2.2), in comparison with TPM from the 3R4F reference cigarette. After 1-week exposure, 3R4F TPM had a strong inhibitory effect on mitochondrial basal and maximal oxygen consumption rates compared to TPM from THS2.2. Alterations in oxidative phosphorylation were accompanied by increased mitochondrial superoxide levels and increased levels of oxidatively damaged proteins in cells exposed to 7.5 MUg/mL of 3R4F TPM or 150 MUg/mL of THS2.2 TPM, while cytosolic levels of reactive oxygen species were not affected. In contrast, the 12-week exposure indicated adaptation of BEAS-2B cells to long term stress. Together, the findings indicate that 3R4F TPM had a stronger effect on oxidative phosphorylation, gene expression and proteins involved in oxidative stress than TPM from the candidate modified-risk tobacco product THS2.2.

AB - Pomegranate (Punica granatum L.) is extensively cultivated in Middle East especially in Iran. For centuries, this fruit has been used in Iranian herbal medicine. Pomegranate peel, seed and juice contain considerable amounts of phenolic compounds and have antioxidant activity. Pomegranate peels, juice and seeds from three regions of Natanz, Shahreza, and Doorak were obtained. Antioxidant activity, total phenolic, flavonoids, and flavonols contents of pomegranate peels, seeds and juices extracts were analyzed. The beta-carotene bleaching test and Folin-Ciocalteu method were applied in this study. The pomegranate peel extract showed high levels of antioxidant activity in comparison to seeds and juices. Doorak peel by 58% had the highest antioxidant activity among two other peels. Total phenolics, flavonoids, and flavonols contents of pomegranate peel were evaluated much more higher than seeds and juices. The significant positive correlation between antioxidant activity and total phenolics was reported. According to achieved results, high antioxidant capacity of pomegranate especially peel, had shed light to use them as natural food preservatives. PMID- 29448089 TI - Probabilistic estimates of heterocyclic amines and polycyclic aromatic hydrocarbons concentrations in meats and breads applicable to exposure assessments. AB - Random effect meta-regressions were constructed to estimate concentrations of two heterocyclic amines (HCA) and eight polycyclic aromatic hydrocarbons (PAH) in meat and breads. Eighteen HCA studies and nine PAH studies of food concentration were assembled. Concentration was computed for beef, poultry, pork, and seafood, and bread. Fixed effect predictors included cooking time, form of the food, cooking method, interaction between form and cooking method, temperature at which the food was cooked, fuel of the flame source, percentage of fat, and other elements. Meat type was significant to all HCAs but only three of the PAHs. Cooking method or an interaction between cooking method and food form was significant in all the overall models for each compound, and 80% of models created for stratifications of the data based on meat type. Improvement on compilations such as the Computerized Heterocyclic Amines Resource for Research in Epidemiology of Disease (CHARRED) database comes from inclusion of additional studies, PAH compounds, more generalizable food categories, more cooking methods (such as smoking), and addition of seafood. Meta-regression allows parameters to be estimated with separation of between-study heterogeneity, and extrapolation of exposures to more foods. Resulting uncertainty estimates are useful in a probabilistic exposure assessment.

AB - Goji (Lycium barbarum L.) berries are emphasized as healthy food or are used widely as dietary supplements. In the present study, the antioxidant and enzyme inhibitory activities of berries extracts from two selected Romanian cultivars (cv. Erma and cv. Biglifeberry) have been evaluated. UHPLC-QTOF-MS analysis results revealed the presence of organic acids, phenolic acids, flavonoids, fatty acids (oxylipins), and spermidine derivatives. In particular, cv. Erma showed an important tyrosinase-inhibitory effect, whereas, cv. Biglifeberry had a superior antioxidant capacity. Particularly, results provided by the CUPRAC assay showed the highest antioxidant capacity values (26.91 mg TE/g and 35.41 mg TE/g, for 'Erma' and 'Biglifeberry', respectively). Toxicological properties of the extracts were evaluated with human embryonic kidney cells (HEK-293) using the cytotoxicity analysis platform iCELLigence, real-time and label-free impedance technology. No cytotoxic effects were observed in a time- and dose-dependent manner. Overall, Goji berries are a rich source of bioactive compounds with functional properties that need further risk/benefit evaluation when used in foods or health-promoting formulations. PMID- 29448091 TI - Evidence and prospective of plant derived flavonoids as antiplatelet agents: Strong candidates to be drugs of future. AB - Platelets are involved in hemostasis, inflammation, and thrombosis processes. Following a vascular damage, the endothelium releases protein factors, allowing the adhesion of subendothelium to platelets. Then platelets are activated, leading to the secretion of biologically-active ligands including thromboxane A2, adenosine diphosphate and serotonin. Aspirin, clopidogrel and warfarin are the most common drugs used to meet the challenges of platelet aggregation. However, these agents face issues with aspirin resistance and bleeding. New therapeutically effective and safe agents are therefore strongly needed, and natural substances could be ideal candidates. Flavonoids, a chemically diverse group of polyphenols, might be important in this regard. Consumption of flavonoids is responsible for several health-promoting properties. A number of flavonoids have shown outstanding preclinical antiplatelet effects through various mechanisms. Flavonoids could provide an ideal approach as templates for new, clinically-effective and safe antiplatelet agents due to their inherent safety and multiple useful pharmacological hits. This review aims to report data from literature regarding flavonoids with antiplatelet activity, with a particular focus on possible mechanisms of action, pharmacokinetic profiles and overall safety, thus providing a strong rationale for the design of selective and well-directed antiplatelet agents of natural origin. PMID- 29448092 TI - Investigation on bisphenol A levels in human milk and dairy supply chain: A review. AB - Bisphenol A (BPA), widely used as additive in food packaging, is an environmental and food contaminant that shows a weak estrogenic activity in general population and toxicity in the infant population. A temporary tolerable daily intake (t-TDI) of 4 MUg/kg bw/day and a migration limit of 0.6 mg/kg in food from plastic materials, intended to come in contact with food, were fixed. Dietary milk is important in the human diet. The review investigated the contamination levels in human milk and along the dairy supply chain. Despite the reported levels are generally below the fixed limits, breast milk is considered a continuous low level exposure to endocrine-active compounds for infants. In addition, BPA residues are detected in milk and dairy products posing a risk to human health. BPA enters into milk chain via multiple pathways at various points during milk production (e.g., PVC tubing used during the milking process, transfer from bulk milk to storage tanks, during milk processing). To prevent or mitigate this hazard, a specific TDI for infants is recommended and evaluation of risk factors at each phase of the dairy supply chain, in the quality systems, is recommended. PMID- 29448093 TI - Probabilistic assessment of dietary exposure to heterocyclic amines and polycyclic aromatic hydrocarbons from consumption of meats and breads in the United States. AB - This probabilistic analysis estimated daily dietary exposures of the US population to heterocyclic amines and polycyclic aromatic hydrocarbons from meat and some varieties of bread. Mean concentrations for these foods grouped by cooking method and food form were combined with consumption data from the National Health and Nutritional Examination Survey (NHANES). Mean exposure to HCA2 (PhIP + MeIQx), was 565.3 ng/day (95% CrI: 403.73, 726.88), and to PAH8 (sum of BaP, ChY, BaA, BkF, BbF, DahA, IP, and BghiP), was 634.8 ng/day (568.38, 701.15). HCA2 exposures were not significantly different between meat types, but multiple differences were found between cooking types. Exposures to PAH8 in the mean consumers differed significantly between cooking methods, and were higher for beef than poultry (mean difference: 983 ng, 95%CrI: -77.0, 4076.0) and pork (990 ng, 95%CrI: 23.7, 4061.8), but not for any other food comparisons. Tradeoffs between exposures associated with a typical portion size of potential food replacements were also examined. Differences in HCA2 and PAH8 exposure are primarily driven by the preparation method rather than the type of meat. These findings should be considered in future studies linking PAH and HCA compounds with human health impacts. PMID- 29448094 TI - The prevalence and antimicrobial resistance of Listeria spp in raw milk and traditional dairy products delivered in Yazd, central Iran (2016). AB - Listeria monocytogenes is an important foodborne pathogen which its data in Iranian dairy products is limited. A total of 545 samples of traditional dairy products (raw milk, traditional cheese, traditional butter, traditional curd, and traditional ice cream) were collected from traditional dairy shops located in Yazd, Iran. L. monocytogenes was isolated, and positive samples were confirmed by polymerase chain reaction. Antibiotic sensitivity test was conducted to determine the antibiotic resistance. Listeria species were isolated from 11.7% samples. 4.03% samples were identified as L. monocytogenes, 5.6% as L. innocua, 1.8% as L. seeligeri, and 0.18% L. murrayi. All L. monocytogenes isolates were resistant to tetracycline, chloramphenicol, penicillin, and amoxicillin/clavulanic acid. Consumption of raw milk and its traditional products prepared inadequate heat treatment and the lack of appropriate control measures might lead to serious health problems. As our results show, the Iranian food safety authorities should set up an effective standard to screen all susceptible food for the presence of Listeria spp. PMID- 29448095 TI - Advances in analytical tools for high throughput strain engineering. AB - The emergence of inexpensive, base-perfect genome editing is revolutionising biology. Modern industrial biotechnology exploits the advances in genome editing in combination with automation, analytics and data integration to build high throughput automated strain engineering pipelines also known as biofoundries. Biofoundries replace the slow and inconsistent artisanal processes used to build microbial cell factories with an automated design-build-test cycle, considerably reducing the time needed to deliver commercially viable strains. Testing and hence learning remains relatively shallow, but recent advances in analytical chemistry promise to increase the depth of characterization possible. Analytics combined with models of cellular physiology in automated systems biology pipelines should enable deeper learning and hence a steeper pitch of the learning cycle. This review explores the progress, advances and remaining bottlenecks of analytical tools for high throughput strain engineering. PMID- 29448096 TI - AMPK alleviates endoplasmic reticulum stress by inducing the ER-chaperone ORP150 via FOXO1 to protect human bronchial cells from apoptosis. AB - Chronic obstructive pulmonary disease (COPD), is characterized by inflammation of airways accompanied by a progressive destruction of lung parenchyma. This process is initiated in most cases by cigarette smoking. In this study we investigated the role of AMP activated protein kinase (AMPK) in cigarette smoke extract (CSE) induced airway epithelial cell apoptosis as a consequence of endoplasmic reticulum stress (ER stress). Exposure of human bronchial epithelial cells (HBEpC) to CSE resulted in apoptosis as detected using Annexin V-PI flow cytometry. However, co-treatment with N1-(beta-d-ribofuranosyl)-5-aminoimidazole 4-carboxamide (AICAR), a pharmacological activator of AMPK, significantly increased cell protection against ER stress-induced apoptosis by upregulating the 150 kDa oxygen-regulated protein (ORP150), which functions as an ER-associated chaperone, with concomitant elevation of FOXO1, a critical transcription factor regulating ORP150 expression. Lentiviral silencing of AMPK or FOXO1 using short hairpin (sh) RNA resulted in a significant decrease of ORP150 and an elevation of CCAAT/enhancer-binding protein-homologous protein (CHOP) resulting in ER stress and apoptosis of HBEpC. Together, our results strongly suggest that AMPK can activate ORP150 through FOXO1 pathway and confer protection against ER stress induced apoptosis of airway epithelial cells following exposure to CSE. Thus, AMPK may serve as a likely therapeutic target for clinical and sub-clinical interventions in COPD. PMID- 29448098 TI - Differences in TLR7/8 activation between monocytes and macrophages. AB - The recognition of single-stranded RNA by TLR7/8 leads to the production of NF kappaB-mediated cytokines and type I IFNs. However, the role of TLR7/8 activation in monocytes and macrophages is still unclear. The aim of this study was to investigate the differences in the activation of TLR7/8 between these two cell types. Microarray analysis, qRT-PCR and flow cytometry were used to analyse TLR7/8 signalling pathways in monocytes and macrophages after stimulation with agonists. Our data indicated that TLR8 agonists activated the NF-kappaB- and IRF mediated pathways in THP-1 cells, whereas TLR7 agonists did not. However, silent TLR8 and enhanced TLR7 expression could increase TLR7-induced NF-kappaB activation in monocytes. TLR7 and TLR8 agonists induced NF-kappaB activation but no ISG response in PMA-differentiated THP-1 cells. The mRNA levels of pro inflammatory cytokine were elevated upon CL075 stimulation in macrophages compared to monocytes. Thus, TLR7 and TLR8 might modulate different immune responses in monocytes and macrophages. PMID- 29448097 TI - Selective degradation of BET proteins with dBET1, a proteolysis-targeting chimera, potently reduces pro-inflammatory responses in lipopolysaccharide activated microglia. AB - Bromodomain and extraterminal (BET) proteins are essential to pro-inflammatory gene transcription. The BET family proteins, BRD2, BRD3, BRD4, and testis specific BRDT, couple chromatin remodeling to gene transcription, acting as histone acetyltransferases, scaffolds for transcription complexes, and markers of histone acetylation. To initiate an inflammatory response, cells undergo de novo gene transcription requiring histone-modifying proteins to make DNA wrapped around histones more or less readily available to transcription complexes. Because BET proteins are the gatekeepers of nuclear factor-kappaB (NF-kappaB) dependent gene transcription, we hypothesized that degradation of BET proteins, particularly BRD2 and BRD4, with the proteolysis-targeting chimera (PROTAC) dBET1 would dampen the pro-inflammatory response in microglia subjected to lipopolysaccharide (LPS) challenge. Degradation of BRD2 and BRD4 was associated with significantly reduced expression of several pro-inflammatory genes: inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), interleukin (IL)-1beta, tumor necrosis factor-a (TNF-alpha), IL-6, chemokine (C-C motif) ligand 2 (CCL2), and matrix metalloproteinase-9 (MMP-9). This is the first study showing that dBET1-mediated targeted degradation of BET proteins robustly dampens pro-inflammatory responses in LPS-stimulated microglia. These data suggest that BET degradation with dBET1 will likely reduce expression of pro-inflammatory genes in in vivo neuroinflammatory models associated with microglial/immune cell activation. PMID- 29448099 TI - JAB1 regulates CPNE1-related differentiation via direct binding to CPNE1 in HiB5 hippocampal progenitor cells. AB - Copine1 (CPNE1), has tandem C2 domains and an A domain. We previously demonstrated that CPNE1 directly induces neuronal differentiation via Protein kinase B (AKT) phosphorylation in the hippocampal progenitor cell line, HiB5. To better understand its cellular function, we carried out a yeast two-hybrid screening to find CPNE1 binding partners. Among the identified proteins, Jun activation domain-binding protein 1 (JAB1) appears to directly interact with CPNE1. Between CPNE1 and JAB1, the physical interaction was confirmed in vitro and in vivo. In addition the specific binding regions of CPNE1 and JAB1 was confirmed with truncated mutant assay. Furthermore, our results also demonstrate that AKT phosphorylation and expression of the neuronal marker protein are increased when JAB1 is overexpressed in CPNE1 high expressed HiB5 cells. Moreover, overexpression of both CPNE1 and JAB1 in HiB5 cells effectively increased neurite outgrowth. Collectively, our findings suggest that JAB1 activates the neuronal differentiation ability of CPNE1 through the binding of C2A domain in CPNE1 with MPN domain in JAB1. PMID- 29448100 TI - Post-ischemic administration of 5-methoxyindole-2-carboxylic acid at the onset of reperfusion affords neuroprotection against stroke injury by preserving mitochondrial function and attenuating oxidative stress. AB - We previously reported that 5-methoxyindole-2-carboxylic acid (MICA) could induce preconditioning effect in the ischemic brain of rat. In the present study, we addressed the question of whether MICA could also trigger a postconditioning effect in ischemic stroke. To this end, MICA (100 mg/kg body weight) was injected intraperitoneally at the onset of 24 h reperfusion following 1 h ischemia in rat brain. Results indicate that stroked animals treated with MICA showed less brain infarction volume than that of vehicle-treated animals. Further experiments revealed that brain mitochondrial complexes I and IV showed elevated enzymatic activities in MICA treated group and the elevation in complex I activity was likely contributed by seemingly enhanced expression of many complex I subunits, which was determined by mass spectral peptide sequencing. When compared with vehicle-treated rats, the preservation of complexes I and IV activities was shown to be accompanied by enhanced mitochondrial membrane potential, increased ATP production, and decreased caspase-3 activity. Additional studies also indicate the involvement of NQO1 upregulation by the Nrf2 signaling pathway in this MICA postconditioning paradigm. Consequently, attenuated oxidative stress in the MICA treated group reflected by decrease in H2O2 production and protein carbonylation and lipid peroxidation was detected. Taken together, the present study demonstrates that MICA can also induce a postconditioning effect in the ischemic brain of rat and the underlying mechanism likely involves preservation of mitochondrial function, upregulation of cellular antioxidative capacity, and attenuation of oxidative stress. PMID- 29448101 TI - Neuronal calcium channel alpha1 subunit interacts with AMPA receptor, increasing its cell surface localisation. AB - Voltage-activated Ca2+ channels (Cav) play critical roles in excitable cells including neurons. Unlike the well-defined roles of Cav2 for pre-synaptic neurotransmission, the post-synaptic function of Cav2 is unclear. Based on our previous study demonstrating the postsynaptic association of the Cav2 with the AMPA receptor (AMPA-R), in this study we sought to further analyse the Cav2-AMPA R association. We used a step-by-step dissociation of partially purified native Cav2-AMPA-R complexes and co-immunoprecipitation of the Cav2-AMPA-R complexes expressed in HEK293T cells to demonstrate that the main subunit of Cav, alpha1, formed a complex with the AMPA-R without the auxiliary subunits beta, alpha2delta, gamma2/3. The alpha1 subunit increased the cell-surface localisation of the AMPA-R, which could be a post-synaptic function of the Cav2. PMID- 29448102 TI - A universal mini-vector and an annealing of PCR products (APP)-based cloning strategy for convenient molecular biological manipulations. AB - Currently, the most widely used strategies for molecular cloning are sticky-end ligation-based cloning, TA cloning, blunt-end ligation-based cloning and ligase independent cloning. In this study we have developed a novel mini-vector pANY1 which can simultaneously meet the requirements of all these cloning strategies. In addition, the selection of appropriate restriction digestion sites is difficult in some cases because of the presence of internal sites. In this study, an annealing of PCR products (APP)-based sticky-end cloning strategy was introduced to avoid this issue. Additionally, false positives occur during molecular cloning, which increases the workload of isolating positive clones. The plasmid pANY1 contains a ccdB cassette between multiple cloning sites, which efficiently avoids these false positives. Therefore, this mini-vector should serve as a useful tool with wide applications in biosciences, agriculture, food technologies, etc. PMID- 29448103 TI - FGF 21 deficiency slows gastric emptying and reduces initial blood alcohol concentration in mice exposed to acute alcohol in fasting state. AB - Excess alcohol consumption can lead to alcoholic liver disease. Fibroblast growth factor 21 (FGF21) is a metabolic regulator with multiple physiologic functions. Previous study demonstrated that FGF21 deficiency exacerbated alcohol-induced liver injury and exogenous FGF21 administration protected liver from chronic alcohol-induced injury. In this study, we aimed to explore the role of FGF21 in alcohol metabolism in mice. FGF21 knockout (KO) mice and the wild type(WT) control mice were divided into two groups and fasted for 24 h followed by a bonus of alcohol treatment at a dose of 5 g/kg body weight via gavage. Serum alcohol concentration was measured after gavage at 0.5, 2, 3, 4 and 6 h, respectively. At the end, gastric and liver tissues were collected. Serum alcohol concentration of KO mice was significantly lower than that of WT at 0.5 h after alcohol expose. There were no significant differences in alcohol dehydrogenase (ADH) activity and aldehyde dehydrogenase 2 (ALDH2) activity in gastric and liver tissues between WT and the KO mice. However, gastric emptying time of KO mice was much longer than that of WT mice. In addition, the intestinal permeability and serum GLP-1 level of KO mice were significantly higher than that of WT mice. These results suggest that FGF21 deficiency slow gastric emptying rate and indirectly influence initial alcohol metabolism in mice exposed to acute alcohol. Our findings provide additional information for understanding the gastrointestinal mechanism of alcoholic liver disease and other alcohol use disorders. PMID- 29448104 TI - AIM2 regulates vascular smooth muscle cell migration in atherosclerosis. AB - BACKGROUND: Atherosclerosis (AS) is a common pathological basis of various cardiovascular and cerebrovascular diseases. Plaque formation is initiated and triggered by vascular smooth musclecells (VSMCs) migration in vascular wall, which gradually aggravates atherosclerosis progression. Absent in melanoma 2 (AIM2), a member of HIN-200 family, plays an important role in activating inflammasome. However, the role of AIM2 in atherosclerotic plaque progression outside of the inflammasome has not yet been reported. METHODS: The potential effect and the underlying mechanism of AIM2 were investigated in apoliporotein E deficient (ApoE-/-) mice. Murine AIM2 lentivirus, shRNA-AIM2 lentivirus and null lentivirus were constructed and injected intravenously into ApoE-/- mice, which were fed on a high fat diet. The specific mechanism of AIM2 in vascular smooth cells (VSMCs) was explored in vitro. RESULTS: Results showed the aortic atherosclerotic lesion area was larger with AIM2 over-expression, and the number of smooth muscle cells was enhanced in line with the increased AIM2 levels. AIM2 overexpression also induced the increasing expression of MMP2. In vitro studies revealed that different levels of ox-LDL increased AIM2 expression in a time dependent manner. Transwell showed that AIM2 mediated migration in VSMCs. The expression of AIM2 can be inhibited when the ROS inhibitor was used. Additionally, the overexpression and inhibition of AIM2 significantly affects HG induced migration and TGF-beta/SMAD signaling pathway in VSMCs. CONCLUSION: Thus, we demonstrated that AIM2 could promote the progression of atherosclerotic plaque by increasing migration in VSMCs. PMID- 29448105 TI - Casein kinase 2 phosphorylates and stabilizes C/EBPbeta in pancreatic beta cells. AB - During the development of type 2 diabetes, endoplasmic reticulum (ER) stress leads to pancreatic beta cell failure. CCAAT/enhancer-binding protein (C/EBP) beta is highly induced by ER stress and AMP-activated protein kinase (AMPK) suppression in pancreatic beta cells, and its accumulation reduces pancreatic beta cell mass. We investigated the phosphorylation state of C/EBPbeta under these conditions. Casein kinase 2 (CK2) was found to co-localize with C/EBPbeta in MIN6 cells. It phosphorylated S222 of C/EBPbeta, a previously unidentified phosphorylation site. We found that C/EBPbeta is phosphorylated by CK2 under AMPK suppression and ER stress, which are important from the viewpoint of the worsening pathological condition of type 2 diabetes, such as decreased insulin secretion and apoptosis of pancreatic beta cells. PMID- 29448106 TI - Folic acid prevents methotrexate-induced epithelial-mesenchymal transition via suppression of secreted factors from the human alveolar epithelial cell line A549. AB - Methotrexate (MTX) often induces serious lung diseases such as pulmonary fibrosis. Although MTX is known to be a folic acid (FA) antagonist, the effect of FA on MTX-induced lung injury remains unclear. Recent studies indicate that epithelial-mesenchymal transition (EMT) is involved in pulmonary fibrosis. Here, we aimed to clarify the effect of FA on MTX-induced EMT in human alveolar epithelial cell line A549 using conditioned medium (CM). CM was prepared from the supernatants of A549 cells treated with MTX in the absence (CMM) or presence (CMMF) of FA. FA suppressed EMT-like morphological changes and elevated mRNA/protein expression levels of alpha-smooth muscle actin induced by MTX in A549 cells. In addition, CMM induced EMT-like phenotypical changes, whereas CMMF had no effect on the phenotype of A549 cells, indicating that FA may suppress MTX induced EMT via inhibiting the secretion of certain factors into the supernatant of the cells. Furthermore, FA also prevented CMM-induced EMT-like phenotypical changes in A549 cells. These findings indicate that FA may be a useful pharmaceutical for MTX-induced lung injury. PMID- 29448107 TI - Decrease in the cytosolic NADP+-dependent isocitrate dehydrogenase activity through porcine sperm capacitation. AB - In order to understand the molecular mechanisms involved in the sperm capacitation, we have identified the proteins tyrosine-phosphorylated during the capacitation especially in conjunction with the regulation of the levels of reactive oxygen species (ROS) in sperm. In the present study, the effects of the tyrosine phosphorylation of cytosolic NADP+-dependent isocitrate dehydrogenase (IDPc) on its catalytic activity and on the levels of ROS in sperm have been studied. The tyrosine phosphorylated IDPc showed a significantly lowered enzymatic activity. The immunocytochemical analyses using the highly specific antisera against IDPc revealed that IDPc was mainly localized to the principal piece of the porcine sperm flagellum. As IDPc is one of the major NADPH regenerating enzymes in porcine sperm, it is strongly suggested that the decrease in IDPc activity is involved in the increased levels of ROS, which results in the induction of hyperactivated flagellar movement and capacitation. PMID- 29448108 TI - Inhibition of HMGB1 mediates neuroprotection of traumatic brain injury by modulating the microglia/macrophage polarization. AB - Microglia/Macrophages have a double-edged role in secondary brain damage after traumatic brain injury (TBI) depending on polarization toward proinflammatory M1 or anti-inflammatory M2 phenotypes. Recently, high-mobility group box 1 (HMGB1) was found to influence the polarization of macrophages. In this study, glycyrrhizin (GL), an inhibitor of HMGB1, was used to investigate whether the inhibition of HMGB1 could modulate microglia/macrophage polarization after TBI. The results showed that treatment with GL improved the neurological function recovery, reduced the lesion volume, and inhibited the release and expression of HMGB1 after TBI. In addition, the administration of GL suppressed M1 phenotype activation and promoted M2 phenotype activation of microglia/macrophages. In conclusion, the results suggested that GL attenuated TBI by inhibiting M1 phenotype while inducing M2 phenotype activation of microglia/macrophages, at least partly through inhibiting HMGB1. Also, targeting HMGB1 to modulate the microglia/macrophage polarization should be one potential therapeutic approach for TBI. PMID- 29448109 TI - HDAC1 regulates the stability of glutamate carboxypeptidase II protein by modulating acetylation status of lysine 479 residue. AB - Our previous study showed that the level of glutamate carboxypeptidase II (GCPII) protein is regulated by valproic acid, a histone deacetylase (HDAC) inhibitor, through acetylation of lysine residue in the GCPII protein in human astrocytes, U 87MG. The present study further investigated which HDAC subtype is involved in the acetylation of GCPII. The results revealed that GCPII interacted with HDAC1 but not with HDAC2, HDAC3, HDAC4, HDAC5, and HDAC6. Overexpression of catalytic domain (1-56 aa)-deleted HDAC1, which poorly binds to GCPII, enhanced lysine acetylation in GCPII and increased the level of GCPII protein when compared with that of the wild-type HDAC1. Further experiments showed that HDAC1 regulated the stability of GCPII protein. These data suggest that acetylation of GCPII is facilitated by HDAC1, and the acetylated GCPII is more stable than the non acetylated GCPII. Additional experiments using siRNA HDAC1 and by HDAC1 overexpression confirmed the role of HDAC1 in regulating the stability of GCPII protein. Further, database search of acetylation and ubiquitination sites showed four candidate lysine sites in human GCPII protein that can be both acetylated and ubiquitinylated (K207, K479, K491, and K699). Mutation (lysine residues to arginine (R)) analysis showed that in the presence of cycloheximide K479R- and K491R-hGCPII mutants were less ubiquitinylated and degraded, and decrease in the level of GCPII protein by HDAC1 was significantly blocked by K479R mutants. These data suggest that K479 is a possible site of acetylation or ubiquitination. Furthermore, the results also demonstrate that the stability of GCPII protein is regulated by HDAC1 through acetylation at the lysine 479 residue. PMID- 29448110 TI - A set of 14 DIP-SNP markers to detect unbalanced DNA mixtures. AB - Unbalanced DNA mixture is still a difficult problem for forensic practice. DIP STRs are useful markers for detection of minor DNA but they are not widespread in the human genome and having long amplicons. In this study, we proposed a novel type of genetic marker, termed DIP-SNP. DIP-SNP refers to the combination of INDEL and SNP in less than 300bp length of human genome. The multiplex PCR and SNaPshot assay were established for 14 DIP-SNP markers in a Chinese Han population from Shanxi, China. This novel compound marker allows detection of the minor DNA contributor with sensitivity from 1:50 to 1:1000 in a DNA mixture of any gender with 1 ng-10 ng DNA template. Most of the DIP-SNP markers had a relatively high probability of informative alleles with an average I value of 0.33. In all, we proposed DIP-SNP as a novel kind of genetic marker for detection of minor contributor from unbalanced DNA mixture and established the detection method by associating the multiplex PCR and SNaPshot assay. DIP-SNP polymorphisms are promising markers for forensic or clinical mixture examination because they are shorter, widespread and higher sensitive. PMID- 29448111 TI - In silico screening of proteins targeting circulating miRNAs for improved diagnosis of multiple myeloma. AB - Multiple Myeloma (MM) is a B-cell malignancy, which is characterized by the expansion of clonal plasma cells in the bone marrow, leading to abnormal accumulation of monoclonal antibodies in circulation. Certain circulating miRNAs are deregulated in MM and their differential expression profiles in body fluids can be quantified and used to discriminate between the premalignant and malignant stages of MM. Our study identifies protein which would show affinity for a selected panel of circulating miRNAs deregulated in MM. Human RNA binding proteins were identified based on their unique RNA binding domains and their interacting probabilities with the panel of miRNAs deregulated in MM. miR-26 was used as a negative control for interaction studies. 3-D structure of candidate proteins were determined and molecular docking was performed to confirm the results. Five RNA binding proteins TROVE2, CUGBP2, DHX8, PUM2 and DKC1 were used for molecular docking studies. DKC1 showed significant hydrogen bonding as well as remarkable binding affinity values of -17.4 kcal/mol with miR-720 (2 H-bonds), -16 kcal/mol with miR-1246 (1 H-bond) and -16.9 kcal/mol with miR-1308 (3 H bonds). Identified protein-miRNA interaction could be used to develop an economical and reliable ELISA based methodology for improved and sensitive diagnosis of MM patients.

AB - Liposomal formulations entrapping a vast number of molecules have improved cancer therapies overcoming certain pharmacokinetic (PK) and pharmacodynamic limitations, many of which are associated with tumor characteristics. In this context, immunoliposomes represent a new strategy that has been widely investigated in preclinical cancer models with promising results, although few have reached the stage of clinical trials. This contrasts with the emerging clinical application of monoclonal antibodies (mAbs). This formulation allows the conjugation of different mAbs or antibody derivatives, such as monovalent variable fragments Fab', to the polymers covering the surface of liposomes. The combination of this targeting strategy together with drug encapsulation in a single formulation may contribute to enhance the efficacy of these associated agents, reducing their toxicities. In this paper we will consider how factors such as particle size, lipid composition and charge, lipid-polymer conjugation, method of production and type of ligand for liposome coupling influence the efficacy of these formulations. Furthermore, the high inter-individual variability in the tumor microenvironment, as well as the poor experimental designs for the PK characterization of liposomes, make the establishment of the relationship between plasma or tumor concentrations and efficacy difficult. Thus, adequate dosing regimens and patient stratification regarding the target expression may contribute to enhance the possibility of incorporating these immunoliposomes into the therapeutic arsenal for cancer treatments. All these issues will be briefly dealt with here, together with a section showing the state of the art of those targeted liposomes that are coming up for testing in clinical trials. Finally, some insights into future developments such as the combination of specificity and controlled release, based on the application of different stimuli, for the manipulation of stability and cargo release, will be offered. This has been included in order to highlight the new opportunities for targeted liposomes, including immunoliposomes.

AB - Primary familial brain calcification (PFBC), otherwise known as Fahr's disease, is a rare autosomal dominant condition with manifestations of movement disorders, neuropsychiatric symptoms, and epilepsy in a minority of PFBC patients. The clinical presentation of epilepsy in PFBC has not been described in detail. We present a paediatric patient with PFBC and refractory focal epilepsy based on seizure semiology and ictal EEG, but with generalized interictal EEG abnormalities. The patient was found to have a SLC20A2 mutation known to be pathogenic in PFBC, as well as a variant of unknown significance in SCN2A. This case demonstrates that the ictal EEG is important for accurately classifying epilepsy in affected subjects with PFBC. Further, epilepsy in PFBC may be a polygenic disorder. PMID- 29448118 TI - Calcium channel blockers as drug repurposing candidates for gestational diabetes: Mining large scale genomic and electronic health records data to repurpose medications. AB - New therapeutic approaches are needed for gestational diabetes mellitus (GDM), but must show safety and efficacy in a historically understudied population. We studied associations between electronic medical record (EMR) phenotypes and genetic variants to uncover drugs currently considered safe in pregnancy that could treat or prevent GDM. We identified 129 systemically active drugs considered safe in pregnancy targeting the proteins produced from 196 genes. We tested for associations between GDM and/or type 2 diabetes (DM2) and 306 SNPs in 130 genes represented on the Illumina Infinium Human Exome Bead Chip (DM2 was included due to shared pathophysiological features with GDM). In parallel, we tested the association between drugs and glucose tolerance during pregnancy as measured by the glucose recorded during a routine 50-g glucose tolerance test (GTT). We found an association between GDM/DM2 and the genes targeted by 11 drug classes. In the EMR analysis, 6 drug classes were associated with changes in GTT. Two classes were identified in both analyses. L-type calcium channel blocking antihypertensives (CCBs), were associated with a 3.18 mg/dL (95% CI -6.18 to 0.18) decrease in glucose during GTT, and serotonin receptor type 3 (5HT-3) antagonist antinausea medications were associated with a 3.54 mg/dL (95% CI 1.86 5.23) increase in glucose during GTT. CCBs were identified as a class of drugs considered safe in pregnancy could have efficacy in treating or preventing GDM. 5HT-3 antagonists may be associated with worse glucose tolerance.

AB - PURPOSE: To evaluate modified Dixon MRI techniques in hepatic fat estimation and to assess the effect of cirrhosis. METHODS: 235 patients who underwent liver MRI were included. Correlation between modified Dixon techniques with MRS was assessed. Accuracy of MR techniques in hepatic fat estimation was calculated, and the result was compared between patients with/without liver cirrhosis. RESULTS: Correlation between modified Dixon and MRS was better in group without liver cirrhosis, and accuracy of modified Dixon method was higher in group without liver cirrhosis. CONCLUSIONS: Modified Dixon techniques estimate hepatic fat fraction noninvasively, but the result can be influenced by the presence of liver cirrhosis. PMID- 29448120 TI - Imaging features of malignant abdominal neuroendocrine tumors with rare presentation. AB - BACKGROUND: Gastroenteropancreatic neuroendocrine tumors (NETs) are rare entities arising from neuroendocrine cells in the gastroenteric tract and pancreas. The purpose of this article is to present four cases of gastroenteropancreatic NETs that featured a challenging diagnosis. CASE PRESENTATION: We report a case series of four NETs, each with different features. All NETs were suspected based on clinical and biochemical data. The workup of the abnormalities was performed with CT, PET or MRI. CONCLUSION: The diagnosis of NETs is challenging and generally based on clinical manifestations, blood biochemical tests, imaging techniques, and pathology. PMID- 29448121 TI - Neonatal distal femoral physeal injury secondary to mechanical trauma of birth: A case report. AB - Physeal injuries occurring secondary to neonatal birth-related trauma are rare entities. Most reported cases of physeal injury involve the distal humerus with only a few published case reports of proximal femoral involvement. So far, we have found only one reported case of neonatal distal femoral epiphysiolysis following Caesarean section. We hereby report a unique case of distal femoral physeal injury with at least partial epiphyseal separation following an uneventful, spontaneous vaginal delivery. Given the uneventful delivery and no known prenatal risk factors, the imaging findings were initially not recognized as being secondary to birth-related injury. Nonaccidental trauma and infection were considered among the possible etiologies for the clinical and imaging findings and a detailed workup for both these entities was performed. Distal femoral physeal injury was considered as a diagnosis of exclusion only after both initial differential considerations were excluded. The authors hope that a knowledge of this entity will facilitate a more accurate differential in cases of thigh swelling and hypomobility in the newborn. PMID- 29448122 TI - Value of 18F-FET PET in adult brainstem glioma. AB - PURPOSE: To investigate 18F-fluoro-ethyl-tyrosine positron emission tomography (FET-PET) imaging characteristics of adult brainstem glioma (BSG). MATERIALS AND METHODS: FET-PET imaging and progression-free survival (PFS) of 16 adult patients with BSG was analyzed (9 high-grade gliomas, 7 low-grade gliomas). SUVmax, TBR, and time activity curves of FET-PET were calculated. RESULTS: Progressive gliomas had higher SUVmax (3.57 +/- 1.47 vs. 1.60 +/- 0.51; p = 0.003) and TBRmax (3.00 +/- 1.12 vs. 1.36 +/- 0.33; p = 0.001) than stable gliomas. Kaplan-Meier analysis showed longer PFS of tumors with TBRmax < 2.0 compared to tumors with TBRmax > 2.0 (665 +/- 32 days versus 220 +/- 39 days; p < 0.001). CONCLUSION: FET-PET uptake might be associated with disease progression in adult BSG. PMID- 29448123 TI - Imaging features of pancreatic metastases: A comparison with pancreatic ductal adenocarcinoma. AB - PURPOSE: To compare imaging features of pancreatic metastases (PM) with those of pancreatic ductal adenocarcinomas (PDAC). METHODS: CT and MR scans of 24 patients with 54 PM and 30 patients with PDAC were reviewed to evaluate the imaging features, which were compared by using a Chi square test. RESULTS: We found a statistically significant difference between PM and PDAC based on location (P < 0.001), margins (P < 0.001), arterial enhancement (P = 0.004), rim enhancement (P < 0.001), pancreatic duct dilatation (P = 0.01), common bile duct dilatation (P = 0.003), vascular involvement (P = 0.02), parenchymal atrophy (P < 0.001), peripancreatic fluid (P = 0.03). CONCLUSION: Imaging features might be helpful to differentiate PM from PDAC. PMID- 29448124 TI - Anatomy and pathology of the canal of Nuck. AB - The canal of Nuck is the female equivalent of the processus vaginalis in the male but is less well known than its male counterpart. It is a rare entity not commonly encountered by radiologists, particularly in the adult population. Knowledge of the embryology and anatomy of the canal of Nuck is essential for identification of the various pathologic conditions that may occur in this location. Moreover, radiologists should be familiar with this entity to compose an appropriate and thorough differential diagnosis of a labial mass/swelling. In this review, we discuss both the anatomy and the more common pathology that can be encountered within it. PMID- 29448125 TI - A critical review of histopathological findings associated with endocrine and non endocrine hepatic toxicity in fish models. AB - Although frequently examined as a target organ for non-endocrine toxicity, histopathological evaluation of the liver is becoming a routine component of endocrine disruption studies that utilize various fish species as test subjects. However, the interpretation of microscopic liver findings can be challenging, especially when attempting to distinguish adverse changes associated with endocrine disrupting substances from those caused by systemic or direct hepatic toxicity. The purpose of this project was to conduct a critical assessment of the available peer-reviewed and grey literature concerning the histopathologic effects of reproductive endocrine active substances (EAS) and non-endocrine acting substances in the livers of fish models, and to determine if liver histopathology can be used to reliably distinguish endocrine from non-endocrine etiologies. The results of this review suggest that few compound-specific histopathologic liver effects have been identified, among which are estrogen agonist-induced increases in hepatocyte basophilia and proteinaceous intravascular fluid in adult male teleosts, and potentially, decreased hepatocyte basophilia in female fish exposed to substances that possess androgenic, anti estrogenic, or aromatase inhibitory activity. This review also used published standardized methodology to assess the credibility of the histopathology data in each of the 117 articles that reported liver effects of treatment, and consequently it was determined that in only 37% of those papers were the data considered either highly credible or credible. The outcome of this work highlights the value of histopathologic liver evaluation as an investigative tool for EAS studies, and provides information that may have implications for EAS hazard assessment. PMID- 29448126 TI - Sub-lethal effects of herbicides penoxsulam, imazamox, fluridone and glyphosate on Delta Smelt (Hypomesus transpacificus). AB - Concerns regarding non-target toxicity of new herbicides used to control invasive aquatic weeds in the San Francisco Estuary led us to compare sub-lethal toxicity of four herbicides (penoxsulam, imazamox, fluridone, and glyphosate) on an endangered fish species Delta Smelt (Hypomesus transpacificus). We measured 17beta-estradiol (E2) and glutathione (GSH) concentrations in liver, and acetylcholinesterase (AChE) activity in brain of female and male fish after 6 h of exposure to each of the four herbicides. Our results indicate that fluridone and glyphosate disrupted the E2 concentration and decreased glutathione concentration in liver, whereas penoxsulam, imazamox, and fluridone inhibited brain AChE activity. E2 concentrations were significantly increased in female and male fish exposed to 0.21 MUM of fluridone and in male fish exposed to 0.46, 4.2, and 5300 MUM of glyphosate. GSH concentrations decreased in males exposed to fluridone at 2.8 MUM and higher, and glyphosate at 4.2 MUM. AChE activity was significantly inhibited in both sexes exposed to penoxsulam, imazamox, and fluridone, and more pronounced inhibition was observed in females. The present study demonstrates the potential detrimental effects of these commonly used herbicides on Delta Smelt. PMID- 29448127 TI - Trophic transfer potential of two different crystalline phases of TiO2 NPs from Chlorella sp. to Ceriodaphnia dubia. AB - Owing to the increase in the usage of titanium dioxide nanoparticles (TiO2 NPs), their release into the aquatic environment is inevitable. In the aquatic ecosystem, TiO2 NPs can bio-magnify at various trophic levels in the food chain through dietary exposure. In the current study, the trophic transfer potential of two crystalline phases of TiO2, anatase and rutile nanoparticles (individual as well as a binary mixture) has been evaluated in the lake water matrix using algae daphnia system. Chlorella sp. and Ceriodaphnia dubia were used as test organisms to represent the algae-daphnia food chain of the freshwater ecosystem. Other than crystallinity, the effect of irradiation (visible and UV-A) was also investigated at the test concentrations, 75, 300, and 1200 MUM. TiO2 NPs treated algal diet produced significant mortality only at the test concentrations, 300 and 1200 MUM. The type of irradiation and crystallinity doesn't have any impact on the mortality of daphnids through the dietary exposure of TiO2 NPs. Comparing the mixture with individual NPs, binary mixture induced less mortality on C. dubia which signifies the antagonistic effect of NPs when they coexist. Statistical modeling confirmed the antagonistic effect of the binary mixture on C. dubia. As individual NPs, anatase and rutile forms showed a maximum Ti accumulation under UV-A and visible irradiation, respectively. BMF of TiO2 NPs has been in validation with the bioaccumulation noted in C. dubia. Individual NPs (75 MUM) showed higher BMF value of ~23 under both UV-A (anatase) and visible (rutile) irradiation. Individual NPs showing higher BMF confirmed their trophic transfer potential in the aquatic food chain, primarily through the diet. In contrast, the binary mixture obtained a higher BMF of 1.9 and 0.79 at 75 and 300 MUM under visible and UV-A irradiation, respectively. The plausible reason behind this decrement was the antagonistic effect of the mixture which significantly reduced their Ti bioaccumulation on C. dubia. PMID- 29448129 TI - Studies to enhance the hyperpolarization level in PHIP-SAH-produced C13-pyruvate. AB - The use of [1-13C]pyruvate, hyperpolarized by dissolution-Dynamic Nuclear Polarization (d-DNP), in in vivo metabolic studies has developed quickly, thanks to the imaging probe's diagnostic relevance. Nevertheless, the cost of a d-DNP polarizer is quite high and the speed of hyperpolarization process is relatively slow, meaning that its use is limited to few research laboratories. ParaHydrogen Induced Polarization Side Arm Hydrogenation (PHIP-SAH) (Reineri et al., 2015) is a cost effective and easy-to-handle method that produces 13C-MR hyperpolarization in [1-13C]pyruvate and other metabolites. This work aims to identify the main determinants of the hyperpolarization levels observed in C13-pyruvate using this method. By dissecting the various steps of the PHIP-SAH procedure, it has been possible to assess the role of several experimental parameters whose optimization must be pursued if this method is to be made suitable for future translational steps. The search for possible solutions has led to improvements in the polarization of sodium [1-13C]pyruvate from 2% to 5%. Moreover, these results suggest that observed polarization levels could be increased considerably by an automatized procedure which would reduce the time required for the work-up passages that are currently carried out manually. The results reported herein mean that the attainment of polarization levels suitable for the metabolic imaging applications of these hyperpolarized substrates show significant promise. PMID- 29448128 TI - Hubs in the human fetal brain network. AB - Advances in neuroimaging and network analyses have lead to discovery of highly connected regions, or hubs, in the connectional architecture of the human brain. Whether these hubs emerge in utero, has yet to be examined. The current study addresses this question and aims to determine the location of neural hubs in human fetuses. Fetal resting-state fMRI data (N = 105) was used to construct connectivity matrices for 197 discrete brain regions. We discovered that within the connectional functional organization of the human fetal brain key hubs are emerging. Consistent with prior reports in infants, visual and motor regions were identified as emerging hub areas, specifically in cerebellar areas. We also found evidence for network hubs in association cortex, including areas remarkably close to the adult fusiform facial and Wernicke areas. Functional significance of hub structure was confirmed by computationally deleting hub versus random nodes and observing that global efficiency decreased significantly more when hubs were removed (p < .001). Taken together, we conclude that both primary and association brain regions demonstrate centrality in network organization before birth. While fetal hubs may be important for facilitating network communication, they may also form potential points of vulnerability in fetal brain development. PMID- 29448130 TI - Optimized slice-selective 1H NMR experiments combined with highly accurate quantitative 13C NMR using an internal reference method. AB - Isotope ratio monitoring by 13C NMR spectrometry (irm-13C NMR) provides the complete 13C intramolecular position-specific composition at natural abundance. It represents a powerful tool to track the (bio)chemical pathway which has led to the synthesis of targeted molecules, since it allows Position-specific Isotope Analysis (PSIA). Due to the very small composition range (which represents the range of variation of the isotopic composition of a given nuclei) of 13C natural abundance values (500/00), irm-13C NMR requires a 10/00 accuracy and thus highly quantitative analysis by 13C NMR. Until now, the conventional strategy to determine the position-specific abundance xi relies on the combination of irm-MS (isotopic ratio monitoring Mass Spectrometry) and 13C quantitative NMR. However this approach presents a serious drawback since it relies on two different techniques and requires to measure separately the signal of all the carbons of the analyzed compound, which is not always possible. To circumvent this constraint, we recently proposed a new methodology to perform 13C isotopic analysis using an internal reference method and relying on NMR only. The method combines a highly quantitative 1H NMR pulse sequence (named DWET) with a 13C isotopic NMR measurement. However, the recently published DWET sequence is unsuited for samples with short T1, which forms a serious limitation for irm-13C NMR experiments where a relaxing agent is added. In this context, we suggest two variants of the DWET called Multi-WET and Profiled-WET, developed and optimized to reach the same accuracy of 10/00 with a better immunity towards T1 variations. Their performance is evaluated on the determination of the 13C isotopic profile of vanillin. Both pulse sequences show a 10/00 accuracy with an increased robustness to pulse miscalibrations compared to the initial DWET method. This constitutes a major advance in the context of irm-13C NMR since it is now possible to perform isotopic analysis with high relaxing agent concentrations, leading to a strong reduction of the overall experiment time. PMID- 29448131 TI - Chirp echo Fourier transform EPR-detected NMR. AB - A new ultra-wide band (UWB) pulse EPR method is introduced for observing all nuclear frequencies of a paramagnetic center in a single shot. It is based on burning spectral holes with a high turning angle (HTA) pulse that excites forbidden transitions and subsequent detection of the hole pattern by a chirp echo. We term this method Chirp Echo Epr SpectroscopY (CHEESY)-detected NMR. The approach is a revival of FT EPR-detected NMR. It yields similar spectra and the same type of information as electron-electron double resonance (ELDOR)-detected NMR, but with a multiplex advantage. We apply CHEESY-detected NMR in Q band to nitroxides and correlate the hyperfine spectrum to the EPR spectrum by varying the frequency of the HTA pulse. Furthermore, a selective pi pulse before the HTA pulse allows for detecting hyperfine sublevel correlations between transitions of one nucleus and for elucidating the coupling regime, the same information as revealed by the HYSCORE experiment. This is demonstrated on hexaaquamanganese(II). We expect that CHEESY-detected NMR is generally applicable to disordered systems and that our results further motivate the development of EPR spectrometers capable of coherent UWB excitation and detection, especially at higher fields and frequencies. PMID- 29448132 TI - MU-Calpain (CAPN1), calpastatin (CAST), and growth hormone receptor (GHR) genetic effects on Angus beef heifer performance traits and reproduction. AB - Genetic marker effects and type of inheritance are estimated with poor precision when minor marker allele frequencies are low. An Angus population was subjected to marker assisted selection for multiple years to equalize CAPN1 haplotypes, CAST, and GHR genetic marker frequencies. The objective was to estimate the pleiotropic effects of these carcass quality oriented markers for body weight, reproduction, and first calf performance traits in 174 replacement beef females which were managed under 2 post-weaning development protocols. Heifers were weighed at 11-, 12-, and 13-mo, at first breeding season pregnancy evaluation, and prior to first calving season. Pubertal status was determined at 11-, 12-, and 13-mo of age. Antral follicles were counted, reproductive tracts were scored, and tract dimensions were measured at 13-mo. Body condition and hip height were scored and measured at pregnancy evaluation and prior to calving season. Heifer pregnancy and weaning rates and ordinal birth date were recorded. Calf body weights at birth and weaning were analyzed. Single df linear contrasts for recessive effects of the GHR heterozygous genotype showed significant decreases of 2.5-3.6% in 11-, 12-, and 13-mo heifer body weights and heifer weight prior to calving. The additive differences between GHR homozygotes were small and not significant for all body weights measured but a 1 wk difference in calf birth date was significant. For all 13-mo uterine measurements, scores, and antral follicle counts, only the CAST dominance contrast for medium antral follicle count was significant. The CAPN1 haplotype with a strong additive effect for increased beef tenderness also had a significant additive effect on calving date. Heifers homozygous for the tender haplotype calved 7.9 days later than heifers homozygous for the tough haplotype. Most heifer reproductive traits were not significantly affected by CAST and CAPN1 markers that are widely used to improve beef tenderness by selection and breeders should not be concerned with how these markers affect reproduction and other heifer traits with the possible exception of CAPN1 effects on calving date. PMID- 29448133 TI - Exposure to the ROCK inhibitor fasudil promotes gliogenesis of neural stem cells in vitro. AB - Fasudil is a clinically approved Rho-associated protein kinase (ROCK) inhibitor that has been used widely to treat cerebral consequences of subarachnoid hemorrhage. It is known to have a positive effect on animal models of neurological disorders including Parkinson's disease and stroke. However, its cellular effect on progenitor populations and differentiation is not clearly understood. While recent studies suggest that fasudil promotes the mobilization of neural stem cells (NSCs) from the subventricular zone in vivo and promotes the differentiation of the C17.2 cerebellar neuroprogenitor line in vitro, it is unclear whether fasudil is involved in the differentiation of primary NSCs. Here, we tested the effect of fasudil on mouse NSCs in vitro, and observed increased gliogenesis in NSCs derived from lateral ventricles. Upon treatment, fasudil promoted characteristics of neurogenesis including phenotypic changes in neural outgrowth and interkinetic nuclear-like movements as an immediate response, while Sox2 expression was maintained and GFAP expression increased. Moreover, the gliogenic response to fasudil medium was observed in both early postnatal and adult NSC cultures. Taken together, our results show that fasudil promotes the differentiation of NSCs into astroglial lineage, suggesting that it could be used to develop novel vitro gliogenesis models and regulate differentiation for neural repair. PMID- 29448134 TI - Enhancing proliferation and optimizing the culture condition for human bone marrow stromal cells using hypoxia and fibroblast growth factor-2. AB - This study aimed to determine the cellular characteristics and behaviors of human bone marrow stromal cells (hBMSCs) expanded in media in a hypoxic or normoxic condition and with or without fibroblast growth factor-2 (FGF-2) treatment. hBMSCs isolated from the vertebral body and expanded in these four groups were evaluated for cellular proliferation/migration, colony-forming units, cell surface characterization, in vitro differentiation, in vivo transplantation, and gene expression. Culturing hBMSCs using a particular environmental factor (hypoxia) and with the addition of FGF-2 increased the cellular proliferation rate while enhancing the regenerative potential, modulated the multipotency related processes (enhanced chondrogenesis-related processes/osteogenesis, but reduced adipogenesis), and increased cellular migration and collagen formation. The gene expression levels in the experimental samples showed activation of the hypoxia-inducible factor-1 pathway and glycolysis in the hypoxic condition, with this not being affected by the addition of FGF-2. The concurrent application of hypoxia and FGF-2 could provide a favorable condition for culturing hBMSCs to be used in clinical applications associated with bone tissue engineering, due to the enhancement of cellular proliferation and regenerative potential. PMID- 29448135 TI - The effect of adding Coping Power Program-Sweden to Parent Management Training effects and moderators in a randomized controlled trial. AB - For children with oppositional defiant disorder (ODD), Parent Management Training (PMT) is a recommended treatment in addition to child Cognitive Behavioral Therapy (child-CBT). There is however a lack of studies investigating the additive effect of group-based child-CBT to PMT for children between 8 and 12 years. The current study investigated the incremental effect of group-based child CBT, based on the Coping Power Program, when added to the Swedish group-based PMT program KOMET. Outcomes were child behavior problems, child prosocial behavior, parenting skills and the moderating effect of child characteristics. One hundred and twenty children 8-12 years with ODD or Disruptive Behavioral Disorder NOS and their parents were randomized either to combined child-CBT and PMT (n = 63) or to PMT only (n = 57) in Swedish Child- and Adolescent Psychiatric settings. Participants were assessed pre- and post-treatment using semi-structured interviews and child- and parent ratings. After treatment, behavior problems were reduced in both groups. Prosocial behavior were significantly more improved in the combined treatment. Parenting skills were improved in both groups. In moderator analyses, behavior problems and prosocial behavior improved significantly more in the combined treatment compared to PMT only in the group of children with high levels of ODD symptoms. PMID- 29448136 TI - Improving functional outcomes in women with borderline personality disorder and PTSD by changing PTSD severity and post-traumatic cognitions. AB - Although functional impairment typically improves during evidence-based psychotherapies (EBPs) for borderline personality disorder (BPD), functional levels often remain suboptimal after treatment. The present pilot study evaluated whether and how integrating PTSD treatment into an EBP for BPD would improve functional outcomes. Participants were 26 women with BPD, PTSD, and recent suicidal and/or self-injurious behavior who were randomized to receive one year of Dialectical Behavior Therapy (DBT) or DBT with the DBT Prolonged Exposure (DBT PE) protocol for PTSD. Five domains of functioning were assessed at 4-month intervals during treatment and at 3-months post-treatment. DBT + DBT PE was superior to DBT in improving global social adjustment, health-related quality of life, and achieving good global functioning, but not interpersonal problems or quality of life. Results of time-lagged mixed effects models indicated that, across both treatments, reductions in PTSD severity significantly predicted subsequent improvement in global social adjustment, global functioning, and health-related quality of life, whereas reductions in post-traumatic cognitions significantly predicted later improvement in all functional outcomes except global social adjustment. These findings provide preliminary evidence supporting the role of change in PTSD severity and trauma-related cognitions as active mechanisms in improving functional outcomes among individuals with BPD and PTSD. PMID- 29448137 TI - Differential metabolism of L-phenylalanine in the formation of aromatic volatiles in melon (Cucumis melo L.) fruit. AB - Studies on the active pathways and the genes involved in the biosynthesis of L phenylalanine-derived volatiles in fleshy fruits are sparse. Melon fruit rinds converted stable-isotope labeled L-phe into more than 20 volatiles. Phenylpropanes, phenylpropenes and benzenoids are apparently produced via the well-known phenylpropanoid pathway involving phenylalanine ammonia lyase (PAL) and being (E)-cinnamic acid a key intermediate. Phenethyl derivatives seemed to be derived from L-phe via a separate biosynthetic route not involving (E) cinnamic acid and PAL. To explore for a biosynthetic route to (E)-cinnamaldehyde in melon rinds, soluble protein cell-free extracts were assayed with (E)-cinnamic acid, CoA, ATP, NADPH and MgSO4, producing (E)-cinnamaldehyde in vitro. In this context, we characterized CmCNL, a gene encoding for (E)-cinnamic acid:coenzyme A ligase, inferred to be involved in the biosynthesis of (E)-cinnamaldehyde. Additionally we describe CmBAMT, a SABATH gene family member encoding a benzoic acid:S-adenosyl-L-methionine carboxyl methyltransferase having a role in the accumulation of methyl benzoate. Our approach leads to a more comprehensive understanding of L-phe metabolism into aromatic volatiles in melon fruit. PMID- 29448138 TI - Dual-targeting antitumor hybrids derived from Pt(IV) species and millepachine analogues. AB - Many strategies have been developed to circumvent the shortcomings of Pt(II) based chemotherapy, but the inherent problems still have not been effectively resolved. Here we report a new series of dual-targeting Pt(IV) prodrugs, conjugates of millepachine analogues with the related Pt(IV) complexes derived from cisplatin or oxaliplatin, respectively, which can inhibit tubulin polymerization and induce DNA damage. Among them, compound 19 possessed excellent antitumor activities against the tested human cancer cell lines, and arrested the cell cycle at the G2/M phases and ultimately induced cell apoptosis. Interestingly, its low cytotoxicity toward two human normal cells and sensitivity toward two cisplatin-resistant cells revealed the possibility for cancer therapy. More importantly, 19 displayed excellent antitumor efficacy in the SK-OV-3 xenograft model better than cisplatin and the corresponding millepachine analogue. Our research provided an efficient strategy for multi-targeting antitumor drug development. PMID- 29448139 TI - Discovery and optimization of 1-(1H-indol-1-yl)ethanone derivatives as CBP/EP300 bromodomain inhibitors for the treatment of castration-resistant prostate cancer. AB - The CREB (cAMP responsive element binding protein) binding protein (CBP) and its homolog EP300 have emerged as new therapeutic targets for the treatment of cancer and inflammatory diseases. Here we report the identification, optimization and evaluation of 1-(1H-indol-1-yl)ethanone derivatives as CBP/EP300 inhibitors starting from fragment-based virtual screening (FBVS). A cocrystal structure of the inhibitor (22e) in complex with CBP provides a solid structural basis for further optimization. The most potent compound 32h binds to the CBP bromodomain and has an IC50 value of 0.037 MUM in the AlphaScreen assay which was 2 times more potent than the reported CBP bromodomain inhibitor SGC-CBP30 in our hands. 32h also exhibit high selectivity for CBP/EP300 over other bromodomain-containing proteins. Notably, the ester derivative (29h) of compound 32h markedly inhibits cell growth in several prostate cancer cell lines including LNCaP, 22Rv1 and LNCaP derived C4-2B. Compound 29h suppresses the mRNA expression of full length AR (AR-FL), AR target genes and other oncogene in LNCaP cells. 29h also reduces the expression of PSA, the biomarker of prostate cancer. CBP/EP300 inhibitor 29h represents a promising lead compound for the development of new therapeutics for the treatment of castration-resistant prostate cancer. PMID- 29448140 TI - Synthesis and structure-activity relationships of asymmetric dimeric beta carboline derivatives as potential antitumor agents. AB - A series of newly asymmetric dimeric beta-carbolines with a spacer of 4-6 methylene units between the indole nitrogen and the harmine oxygen were synthesized. Structures of all the novel synthesized compounds were confirmed by their spectral and analytical studies. All of the synthesized compounds were screened for their in vitro cytotoxic activity against nine cancer cell lines. The results revealed that compounds 7c, 7o and 7s exhibited the highest cytotoxic activities with IC50 values of less than 20 MUM against the tumor cell lines tested. Acute toxicities and antitumor efficacies of the selected compounds in mice were also evaluated, and compound 7o exhibited potent antitumor activities with the tumor inhibition rate of over 40%. The wound healing assay displayed a specific impairment in the motility of the HT-29 cells, which suggested the anti metastatic potential of compound 7o. Moreover, compound 7o had obvious angiogenesis inhibitory effects in the chicken chorioallantoic membrane (CAM) assay. Preliminary structure-activity relationship (SAR) analysis indicated that: (1) 3-phenylpropyl substituent at the N9-position of the indole ring was the most suitable group giving rise to potent cytotoxic agents; (2) the spacer length affected the antitumor potencies, and four methylene units were more favorable. PMID- 29448141 TI - Biocompatible and biodegradable zeolitic imidazolate framework/polydopamine nanocarriers for dual stimulus triggered tumor thermo-chemotherapy. AB - Zeolitic imidazolate frameworks (ZIFs) have attracted great interest as pH sensitive drug carrier because of high drug loading and intrinsic biodegradability. In this work, a biocompatible NIR and pH-responsive drug delivery nanoplatform based on ZIFs (PDA-PCM@ZIF-8/DOX) is synthesized for in vivo cancer therapy. The biocompatibility of ZIFs is greatly improved by polydopamine (PDA) modifying and proved by cytotoxicity and in vivo acute toxicity evaluation. The degradability is also regulated in an appropriate rate. Due to mild reaction condition of ZIFs, the synthesis and drug loading is achieved in one pot with high loading (37.86%) and encapsulation rate (78.76%). Meanwhile, PDA acts as a photothermal transfer agent to trigger thermal response switch of phase change materials for NIR controlled drug release. Under the dual stimulus of NIR and acid environment, the drug release is as high as 78%, while only 21% is released without stimulus, showing a remarkable effect of control release. In vivo anti-tumor experiments demonstrate the high tumor inhibition rate of photothermal-chemotherapy group with a significant synergistic effect. The biocompatible and biodegradable drug delivery platform based on ZIFs has shown great promise for future clinic cancer therapy. PMID- 29448142 TI - Metabolomics facilitates the discrimination of the specific anti-cancer effects of free- and polymer-conjugated doxorubicin in breast cancer models. AB - Metabolomics is becoming a relevant tool for understanding the molecular mechanisms involved in the response to new drug delivery systems. The applicability of this experimental approach to cell cultures and animal models makes metabolomics a useful tool for establishing direct connections between in vitro and in vivo data, thus providing a reliable platform for the characterization of chemotherapeutic agents. Herein, we used metabolomic profiles based on nuclear magnetic resonance (NMR) spectroscopy to evaluate the biochemical pathways involved in the response to a chemotherapeutic anthracycline drug (Doxorubicin, Dox) and an N-(2-hydroxypropyl) methacrylamide (HPMA) copolymer-conjugated form (HPMA-Dox) in an in vitro cell culture model and an in vivo orthotopic breast cancer model. We also used protein expression and flow cytometry studies to obtain a better coverage of the biochemical alterations associated with the administration of these compounds. The overall analysis revealed that polymer conjugation leads to increased apoptosis, reduced glycolysis, and reduced levels of phospholipids when compared to the free chemotherapeutic drug. Our results represent a first step in the application of integrated in vitro and in vivo metabolomic studies to the evaluation of drug delivery systems.

AB - The transmission of cell traction force (CTF) to underlying biomaterials is essential for adhered cells to measure and respond to their mechanical microenvironment. Given that the protein layer adsorbed on materials lies between the cells and materials, we hypothesize that the interfacial strength of protein material interfaces (i.e., the adsorption force of proteins, Fad) should have an important role in regulating the transmission of CTF. To test this hypothesis, rat mesenchymal stem cells (rMSCs) were cultured on poly(dimethyl siloxane) (PDMS) substrates with different Fad of fibronectin (FN), and the transmission of CTF was observed by immunofluorescence staining of FN and deformation of PDMS. As revealed, FN on substrates with low Fad is more liable to be desorbed by CTF, which prevents the transmission of CTF to substrates. In contrast, high Fad facilitates the transmission of CTF from rMSCs to the FN layer and PDMS substrates so that rMSCs can perceive the mechanical properties of substrates. We further demonstrated that the divergent transmission of CTF on low and high Fad substrates regulates the lineage specifications of rMSCs. Our study confirms the important role of Fad in CTF transmission and provides a new perspective to gain insights into cell-material interactions and cell fates, which may help to guide the design of better biomaterials. PMID- 29448144 TI - Nanocements produced from mesoporous bioactive glass nanoparticles. AB - Biomedical cements are considered promising injectable materials for bone repair and regeneration. Calcium phosphate composition sized with tens of micrometers is currently one of the major powder forms. Here we report a unique cement form made from mesoporous bioactive glass nanoparticles (BGn). The nanopowder could harden in reaction with aqueous solution at powder-to-liquid ratios as low as 0.4-0.5 (vs. 2.0-3.0 for conventional calcium phosphate cement CPC). The cementation mechanism investigated from TEM, XRD, FT-IR, XPS, and NMR analyses was demonstrated to be the ionic (Si and Ca) dissolution and then reprecipitation to form Si-Ca-(P) based amorphous nano-islands that could network the particles. The nanopowder-derived nanocement exhibited high surface area (78.7 m2/g); approximately 9 times higher than conventional CPC. The immersion of nanocement in simulated body fluid produced apatite nanocrystallites with ultrafine size of 10 nm (vs. 55 nm in CPC). The ultrafine nanocement adsorbed protein molecules (particularly positive charged proteins) at substantial levels; approximately 160 times higher than CPC. The nanocement released Si and Ca ions continuously over the test period of 2 weeks; the Si release was unique in nanocement whereas the Ca release was in a similar range to that observed in CPC. The release of ions significantly stimulated the responses of cells studied (rMSCs and HUVECs). The viability and osteogenesis of rMSCs were significantly enhanced by the nanocement ionic extracts. Furthermore, the in vitro tubular networking of HUVECs was improved by the nanocement ionic extracts. The in vivo neo-blood vessel formation in CAM model was significantly higher by the nanocement implant when compared with the CPC counterpart, implying the Si ion release might play a significant role in pro-angiogenesis. Furthermore, the early bone forming response of the nanocement, based on the implantation in a rat calvarial bone defect, demonstrated a sign of osteoinductivity along with excellent osteocondution and bone matrix formation. Although more studies remain to confirm the potential of nanocement, some of the intriguing physico-chemical properties and the biological responses reported herein support the promise of the new 'nanopowder-based nanocement' for hard tissue repair and regeneration. PMID- 29448145 TI - Concurrent nicotine and tobacco product use among homeless smokers and associations with cigarette dependence and other factors related to quitting. AB - BACKGROUND: Cigarette smoking rates among homeless adults are exceptionally high, contributing to health disparities experienced by this disadvantaged population. Concurrent nicotine and tobacco product use have been shown to result in greater health problems than cigarette smoking alone, and little is known about the rates, motives, and perceived impacts of concurrent use in this group. The purpose of this study is to explore concurrent use rates and constructs of interest among homeless adult daily smokers and to examine differences between concurrent users and non-concurrent users on cigarette dependence, perceived risk of smoking, readiness to quit, and the receipt of recent cessation intervention. METHODS: Participants (N = 396) were recruited from six homeless-serving agencies and/or shelters in Oklahoma City. Enrolled participants completed self-report questionnaires. RESULTS: The rate of concurrent use was high -67.2%. Participants most frequently endorsed lower cost and a desire to cut down on cigarette smoking as motives for concurrent product use. Concurrent users indicated both a greater likelihood of developing a smoking-related disease if they did not quit for good and a greater number of past year quit attempts relative to non-concurrent users. There was no significant difference between concurrent users and non-concurrent users on readiness to quit or having received recent smoking cessation intervention. CONCLUSION: The need for cessation efforts that account for concurrent use for homeless adult smokers is great. Study findings indicate that concurrent users are commonly pursuing the reduction or elimination of cigarette usage and should be specifically targeted for cessation intervention.

PMID- 29448148 TI - Large inter-rater variability on EEG-reactivity is improved by a novel quantitative method. AB - OBJECTIVE: To assess inter-rater agreement on EEG-reactivity (EEG-R) in comatose patients and compare it with a quantitative method (QEEG-R). METHODS: Six 30-s stimulation epochs (noxious, visual and auditory) were performed during EEG on 19 neurosurgical and 11 cardiac arrest patients. Six experts analysed EEGs for reactivity using their habitual methods. QEEG-R was defined as present if >=2/6 epochs were reactive (stimulation/rest power ratio exceeding noise level). Three months patient outcome was assessed by the Cerebral Performance Category Score (CPC) dichotomized in good (1-2) or poor (3-5). RESULTS: Agreement among experts on overall EEG-R varied from 53% to 83% (kappa: 0.05-0.64) and reached 100% (kappa: 1) between two QEEG-R calculators. For the experts, absence of EEG-R yielded sensitivities for poor outcome between 40-85% and specificities between 20-90%, for QEEG-R sensitivity was 40% (CI: 23-68%) and specificity 100% (CI: 69 100%). CONCLUSIONS: There is a large inter-rater variation among experts on EEG-R assessment in comatose patients. QEEG-R is a promising objective prognostic parameter with low inter-rater variation and a high specificity for prediction of poor outcome. SIGNIFICANCE: Clinicians should be cautious when using the traditional, qualitative method, in particular in end-of-life decisions. Implementation of the quantitative method in clinical practice may improve reliability of reactivity assessments. PMID- 29448147 TI - Acceptance and patterns of personal vaporizer use in Australia and the United Kingdom: Results from the International Tobacco Control survey. AB - BACKGROUND: This study examined the prevalence and correlates of (1) perceived social acceptability of personal vaporizer (PV)/e-cigarette use, and (2) reported vaping in public and private places, in the UK and Australia with different regulatory environments for PVs. METHODS: Data analyzed come from 2849 smokers and recent ex-smokers in the UK and Australia who participated in the 2014 wave of the International Tobacco Control Survey. RESULTS: UK respondents were more likely to think vaping is socially acceptable than Australians (56.4% vs. 27.9%; p < 0.001). Having quit smoking, observing vaping in smoke-free (SF) public places, and believing vaping is less harmful than smoking was all significantly associated with greater perceived social acceptability of vaping in both countries. However, vaping status and that of friends and family were more influential in Australia than in the UK. Vaping was reported as much more common in private, than public, settings in both countries. UK vapers were more likely to report vaping in SF public places (OR = 2.66; 95% CI = 1.5-4.7; p < 0.01) and at home (OR = 2.44; 95% CI = 1.5-3.9; p < 0.001), but not in their car when controlling for demographic factors and vaping and smoking status. CONCLUSION: The acceptability of vaping was greater among those who were more exposed to vaping and not just among those with some personal experience of vaping, suggesting no strong social barriers to increased use. Vaping in SF public places was less common than in homes, and both were more common in the UK than in Australia, suggesting some social constraints on use, particularly in Australia. PMID- 29448149 TI - Characterization of the stimulus waveforms generated by implantable pulse generators for deep brain stimulation. AB - OBJECTIVE: To determine the circuit elements required to theoretically describe the stimulus waveforms generated by an implantable pulse generator (IPG) during clinical deep brain stimulation (DBS). METHODS: We experimentally interrogated the Medtronic Activa PC DBS IPG and defined an equivalent circuit model that accurately captured the output of the IPG. We then compared the detailed circuit model of the clinical stimulus waveforms to simplified representations commonly used in computational models of DBS. We quantified the errors associated with these simplifications using theoretical activation thresholds of myelinated axons in response to DBS. RESULTS: We found that the detailed IPG model generated substantial differences in activation thresholds compared to simplified models. These differences were largest for bipolar stimulation with long pulse widths. Average errors were ~3 to 24% for voltage-controlled stimulation and ~2 to 11% for current-controlled stimulation. CONCLUSIONS: Our results demonstrate the importance of including basic circuit elements (e.g. blocking capacitors, lead wire resistance, electrode capacitance) in model analysis of DBS. SIGNIFICANCE: Computational models of DBS are now commonly used in academic research, industrial technology development, and in the selection of clinical stimulation parameters. Incorporating a realistic representation of the IPG output is necessary to improve the accuracy and utility of these clinical and scientific tools. PMID- 29448150 TI - Right prefrontal cortex specialization for visuospatial working memory and developmental alterations in prefrontal cortex recruitment in school-age children. AB - OBJECTIVE: The right prefrontal cortex (PFC) plays an essential role in active processing within visuospatial working memory (VSWM). The aim of this study was to examine developmental changes in the recruitment patterns of the PFC during visuospatial memory tasks in school-age participants. METHODS: We recruited 80 school-age children who were classified into three age groups: 7- to 8-year-old, 9- to 10-year-old, and 11- to 12-year-old children. We used near infrared spectroscopy (NIRS) to measure PFC activity during visuospatial memory task. Memory stimuli were presented either sequentially or simultaneously. RESULTS: In all three groups, right-lateralized PFC activity was observed during sequential presentation, suggesting specialization of the right PFC for VSWM. During simultaneous presentation, right-lateralized PFC activity was not observed in 7- to 8-year-old children or 9- to 10-year-old children. In contrast, PFC activity was right-lateralized in 11- to 12-year-old children. CONCLUSIONS: We suggest that specialization of the right PFC for VSWM is already present before school age, but widely distributed activity in response to visuospatial memory tasks changes to more focal activity in VSWM-specific regions during the early school years. SIGNIFICANCE: Using NIRS, we showed developmental changes in the recruitment patterns of the PFC during visuospatial memory tasks. PMID- 29448152 TI - The clinical utility of qualitative electroencephalography during tilt table testing - A retrospective study. AB - OBJECTIVE: To assess electroencephalography (EEG) changes during tilt table testing in syncope and other orthostatic syndromes. METHODS: We retrospectively reviewed consecutive tilt table studies with simultaneous EEG from April 2014 to May 2016 at our center. All patients had video EEG during tilt table. All patients had at least 10 min of head up tilt unless they had syncope or did not tolerate the study. Video EEG was interpreted by epileptologists. RESULTS: Eighty seven patients met the inclusion criteria. Mean age was 45 years, and 55 were women. Seven patients (~8%) had syncope during tilt table, 11 patients (~12%) had significant neurogenic orthostatic hypotension and a separate group of 11 patients (~12%) had significant orthostatic tachycardia. Valsalva responses were abnormal in 7 of the 11 patients with orthostatic hypotension, suggesting an underlying neurogenic orthostatic hypotension. Visually discernable EEG changes were seen in only 3 patients (~43%) who had syncope and in 1 patient (~9%) with orthostatic tachycardia. CONCLUSIONS: Qualitative EEG analysis based on visual inspection during tilt table study revealed abnormalities in less than half the patients with syncope and a very small fraction with orthostatic tachycardia. SIGNIFICANCE: Routine qualitative EEG recording might not be clinically useful during tilt table studies. PMID- 29448151 TI - Functional cortical source connectivity of resting state electroencephalographic alpha rhythms shows similar abnormalities in patients with mild cognitive impairment due to Alzheimer's and Parkinson's diseases. AB - OBJECTIVE: This study tested the hypothesis that markers of functional cortical source connectivity of resting state eyes-closed electroencephalographic (rsEEG) rhythms may be abnormal in subjects with mild cognitive impairment due to Alzheimer's (ADMCI) and Parkinson's (PDMCI) diseases compared to healthy elderly subjects (Nold). METHODS: rsEEG data had been collected in ADMCI, PDMCI, and Nold subjects (N = 75 for any group). eLORETA freeware estimated functional lagged linear connectivity (LLC) from rsEEG cortical sources. Area under receiver operating characteristic (AUROC) curve indexed the accuracy in the classification of Nold and MCI individuals. RESULTS: Posterior interhemispheric and widespread intrahemispheric alpha LLC solutions were abnormally lower in both MCI groups compared to the Nold group. At the individual level, AUROC curves of LLC solutions in posterior alpha sources exhibited moderate accuracies (0.70-0.72) in the discrimination of Nold vs. ADMCI-PDMCI individuals. No differences in the LLC solutions were found between the two MCI groups. CONCLUSIONS: These findings unveil similar abnormalities in functional cortical connectivity estimated in widespread alpha sources in ADMCI and PDMCI. This was true at both group and individual levels. SIGNIFICANCE: The similar abnormality of alpha source connectivity in ADMCI and PDMCI subjects might reflect common cholinergic impairment. PMID- 29448153 TI - Projecting future climate change impacts on heat-related mortality in large urban areas in China. AB - Global climate change is anticipated to raise overall temperatures and has the potential to increase future mortality attributable to heat. Urban areas are particularly vulnerable to heat because of high concentrations of susceptible people. As the world's largest developing country, China has experienced noticeable changes in climate, partially evidenced by frequent occurrence of extreme heat in urban areas, which could expose millions of residents to summer heat stress that may result in increased health risk, including mortality. While there is a growing literature on future impacts of extreme temperatures on public health, projecting changes in future health outcomes associated with climate warming remains challenging and underexplored, particularly in developing countries. This is an exploratory study aimed at projecting future heat-related mortality risk in major urban areas in China. We focus on the 51 largest Chinese cities that include about one third of the total population in China, and project the potential changes in heat-related mortality based on 19 different global scale climate models and three Representative Concentration Pathways (RCPs). City specific risk estimates for high temperature and all-cause mortality were used to estimate annual heat-related mortality over two future twenty-year time periods. We estimated that for the 20-year period in Mid-21st century (2041-2060) relative to 1970-2000, incidence of excess heat-related mortality in the 51 cities to be approximately 37,800 (95% CI: 31,300-43,500), 31,700 (95% CI: 26,200-36,600) and 25,800 (95% CI: 21,300-29,800) deaths per year under RCP8.5, RCP4.5 and RCP2.6, respectively. Slowing climate change through the most stringent emission control scenario RCP2.6, relative to RCP8.5, was estimated to avoid 12,900 (95% CI: 10,800-14,800) deaths per year in the 51 cities in the 2050s, and 35,100 (95% CI: 29,200-40,100) deaths per year in the 2070s. The highest mortality risk is primarily in cities located in the North, East and Central regions of China. Population adaptation to heat is likely to reduce excess heat mortality, but the extent of adaptation is still unclear. Future heat mortality risk attributable to exposure to elevated warm season temperature is likely to be considerable in China's urban centers, with substantial geographic variations. Climate mitigation and heat risk management are needed to reduce such risk and produce substantial public health benefits. PMID- 29448154 TI - A serine carboxypeptidase-like acyltransferase catalyzes synthesis of indole-3 acetic (IAA) ester conjugate in rice (Oryza sativa). AB - Indole-3-acetic acid (IAA) conjugation is one of mechanisms responsible for regulation of free auxin levels in plants. A new member of the serine carboxypeptidase-like (SCPL) acyltransferases family from Oryza sativa has been cloned and characterized. 1-O-indole-3-acetyl-beta-D-glucose (1-O-IAGlc): myo inositol acyltransferase (IAInos synthase) is an enzyme of IAA ester conjugates biosynthesis pathway that catalyzes transfer of IAA moiety from 1-O-IAGlc to myo inositol forming IA-myo-inositol (IAInos). The OsIAA-At cDNA has been cloned and expressed using yeast and bacterial expression systems. Proteins produced in Saccharomyces cerevisiae and Escherichia coli contained 483 and 517 amino acids, respectively. The enzyme functionally expressed in both expression systems exhibits 1-O-IAGlc-dependent acyltransferase activity. Analysis of amino acid sequence confirmed that rice IAInos synthase belongs to the SCPL protein family. Recombinant IAInos synthases produced in yeast and bacterial expression systems have been partially characterized and their properties have been compared to those of the native enzyme obtained from 6-days-old rice seedlings by biochemical approach. The oligosaccharide component of the protein enzyme is not necessary for its catalytic activity. The native enzyme showed the lowest specific activity of 5.01 nmol min-1 mg-1 protein, whereas the recombinant enzymes produced in yeast and bacteria showed specific activity of 18.75 nmol min-1 mg-1 protein and 18.09 nmol min-1 mg-1 protein, respectively. The KM values for myo-inositol were similar for all three forms of the enzyme: 1.38, 0.83, 1.0 mM for native, bacterial and yeast protein, respectively. Both recombinant forms of IAInos synthase and the native enzyme also have the same optimal pH of 7.4 and all of them are inhibited by phenylmethylsulfonyl fluoride (PMSF), specific inhibitor of serine carboxypeptidases. PMID- 29448155 TI - Characterization of a SUPERMAN-like Gene, MdSUP11, in apple (Malus * domestica Borkh.). AB - Arabidopsis SUPERMAN and its family members of its family play important roles in plant growth and floral organ development; yet much less is known about their functions expanding in apple tree development. Previous work has identified 12 SUP-like genes in the apple (Malus * domestica Borkh.) genome, and the MdSUP11 which is expressed in both vegetative and reproductive organs of apple. However, the function of MdSUP11 remains obscure. In this study, the beta-glucuronidase expression driven by the MdSUP11 native promoter was detected in roots, young leaves, and floral organs of transgenic Arabidopsis. In transgenic tobacco, overexpression of MdSUP11 lead to dwarfism, aberrant leaf shapes, and morphological changes of floral organs. Endogenous concentrations of auxin (indole-3-acetic acid), abscisic acid, isopentenyl adenosine and zeatin riboside were significantly higher in young MdSUP11-transformed tobacco plants than in non transformed plants. Gene expression analysis using real-time quantitative PCR showed up-regulation of NtDFR2 and NtANS1 expression in unopened transgenic flowers, whereas NtCHS expression was not changed significantly. Together, these results suggest that MdSUP11 is associated with apple's vegetative and reproductive development. Its overexpression in tobacco affects leaf and flower organ development and plant height; potentially by changing NtDFR2 and NtANS1 expression and endogenous levels of indole-3-acetic acid, cytokinins and abscisic acid. PMID- 29448156 TI - Improved methane removal in exhaust gas from biogas upgrading process using immobilized methane-oxidizing bacteria. AB - Methane in exhaust gas from biogas upgrading process, which is a greenhouse gas, could cause global warming. The biofilter with immobilized methane-oxidizing bacteria (MOB) is a promising approach for methane removal, and the selections of inoculated MOB culture and support material are vital for the biofilter. In this work, five MOB consortia were enriched at different methane concentrations. The MOB-20 consortium enriched at the methane concentration of 20.0% (v/v) was then immobilized on sponge and two particle sizes of volcanic rock in biofilters to remove methane in exhaust gas from biogas upgrading process. Results showed that the immobilized MOB performed more admirable methane removal capacity than suspended cells. The immobilized MOB on sponge reached the highest methane removal efficiency (RE) of 35%. The rough surface, preferable hydroscopicity, appropriate pore size and particle size of support material might favor the MOB immobilization and accordingly methane removal. PMID- 29448157 TI - In situ surface decoration of Fe3C/Fe3O4/C nanosheets: Towards bi-functional activated carbons with supercapacitance and efficient dye adsorption. AB - This work reports a bi-functional activated porous carbon (PC) prepared from a biomass tofu, with excellent capacities for charge storage and adsorption of organic dyes, which is enabled by decorating with Fe3C/Fe3O4/C nanosheets. The in situ growth and self-assembly of the nanosheets on the carbon surface are achieved by a one-step catalytic carbonization of tofu simultaneously with FeCl3 and ZnCl2 catalysts. Due to the high surface area and unique iron compounds containing and sheet-like structures, the PCs exhibit an electrochemical capacitance of 315 F g-1 at 0.5 A g-1 as supercapacitor electrodes, and an ultrahigh adsorption capacity of 918 mg g-1 for methylene blue (MB) and 868 mg g 1 for Rhodamine B (RhB). This study provides a new perspective for understanding the effects of surface engineering on increasing charge storage and dye adsorption ability of biomass-derived PCs as well as for developing bi-functional PCs with novel magnetic properties. PMID- 29448158 TI - Despacito: the slow evolutionary changes in plant microRNAs. AB - MicroRNAs (miRNAs) are key regulators of gene expression. A handful of miRNAs are broadly conserved in land plants, while the majority are lineage specific; this review describes the processes by which new miRNAs are hypothesized to have emerged. Two major models describe miRNA origins, firstly, de novo emergence via inverted duplication of target gene fragments, and secondly, the expansion and neofunctionalization of existing miRNA families. The occasional acquisition of target sites by previously un-targeted genes adds further dynamism to the process by which miRNAs may shift roles during evolution. Additional factors guiding miRNA evolution include functional constraints on their length and the importance of precursor conservation that is observed in regions above or below the mature miRNA duplex; these regions represent recognition sites for components of biogenesis machinery and direct precursor processing. Insights into the mechanisms of miRNA emergence and divergence are important for understanding plant genome evolution and the impact of miRNA regulatory networks. PMID- 29448159 TI - Polyploid Arabidopsis species originated around recent glaciation maxima. AB - Polyploidy may provide adaptive advantages and is considered to be important for evolution and speciation. Polyploidy events are found throughout the evolutionary history of plants, however they do not seem to be uniformly distributed along the time axis. For example, many of the detected ancient whole-genome duplications (WGDs) seem to cluster around the K/Pg boundary (~66Mya), which corresponds to a drastic climate change event and a mass extinction. Here, we discuss more recent polyploidy events using Arabidopsis as the most developed plant model at the level of the entire genus. We review the history of the origin of allotetraploid species A. suecica and A. kamchatica, and tetraploid lineages of A. lyrata, A. arenosa and A. thaliana, and discuss potential adaptive advantages. Also, we highlight an association between recent glacial maxima and estimated times of origins of polyploidy in Arabidopsis. Such association might further support a link between polyploidy and environmental challenge, which has been observed now for different time-scales and for both ancient and recent polyploids. PMID- 29448160 TI - Multi-plane, multi-joint lower extremity support moments during a rapid deceleration task: Implications for knee loading. AB - The principle of lower limb support, and the contribution of hip, knee and ankle moments to an overall limb support strategy for an impact-like, rapid deceleration movement may help explain individual moment magnitude changes, thereby providing insight into how injury might occur or be avoided. Twenty subjects performed single limb, impact-like, deceleration landings at three different knee flexion angles in the range of 0-25, 25-50 and 50-75 degrees . Kinematic and kinetic measures identified hip, knee and ankle moment contribution to limb support moments (LSMs) in three planes. Repeated measures ANOVA compared LSMs and the contribution of individual joint moments at initial contact (IC) and 50 ms after. There were no significant differences in the overall LSMs at IC in any plane when the deeper knee flexion landings (25-50 degrees and 50-75 degrees ) were compared to the 0-25 degrees landing position but there were significant changes in the 50 ms period after IC. There were greater overall extensor LSMs, less resistance to medial opening of the knee and decreased support against internal tibia rotation when landing in greater knee flexion. The role of individual joint moments changed rapidly in the 50 ms period after initial landing; and, the relative contribution of the hip and ankle moments depended on the degree of limb flexion at landing. Analyses of individual joint moments emphasized the critical role that the hip joint moments have in balancing potentially injurious knee moments in all three planes for all three landing conditions. PMID- 29448161 TI - How does lower limb dominance influence postural control movements during single leg stance? AB - The main purposes of the current study were to examine bilateral asymmetry in postural control during single-leg standing between the dominant and non-dominant legs using a novel analysis approach based on principal component analysis (PCA). It was hypothesized that the asymmetry might manifest as differences in the coordinative structure (control strategies), or as differences in the frequency or regularity of corrective interventions of the motor control system. The static and dynamic leg dominance of 26 active young adults (14 males and 12 females) was determined from their preferred leg for dynamic and for static tasks. Then postural movements during one-leg standing were recorded with a standard marker based motion capture system and analyzed by a PCA. The coordinative structure of postural movements was quantified using the relative variance of the principal movement components (PMs). Then the PMs were differentiated to obtain postural accelerations, from which two variables characterizing the activity (frequency and regularity) of the postural control system were derived. There were no differences in the coordinative structure, neither for dynamic nor for static leg preference. However, both variables characterizing asymmetries in the postural accelerations showed significant differences in specific PMs. Dynamic leg dominance yielded more and larger effects than static leg dominance. In the opinion of the authors, the PM-specificity of limb dominance agrees with principles of movement control derived from optimal feedback control theory. In summary, the current study suggests that leg dominance should be considered in clinical testing; different effects in different movement components should be expected; and one-leg standing should be seen as a dynamic, rather than as a static task. PMID- 29448162 TI - Cognitive-motor dual-task interference modulates mediolateral dynamic stability during gait in post-stroke individuals. AB - Gait asymmetry and dynamic balance impairments observed in post-stroke individuals increase their risk of fall. Moreover, walking while performing a cognitive task (i.e. dual-task) disturbs the control of balance in post-stroke individuals. Here we investigated the mediolateral dynamic stability in twenty two community-dwelling participants (12 post-strokes and 10 healthy controls) while walking in single-task (normal gait) and four different dual-tasks (cognitive-motor interference). Positions of the extrapolated center of mass and mediolateral widths of both margin of stability and base of support were extracted from 35 marker trajectories. Post-stroke participants presented larger margin of stability and base of support than controls during single-task (both p < 0.01), with a larger margin of stability on the non-paretic side than on the paretic side at ipsilateral foot-strike (p < 0.05). No significant effect of the dual-task was found between groups. In post-stroke participants, dual-task induced slight modification of the mediolateral stability strategy, as the margin of stability was not different between the two limbs at foot-strike, and significantly reduced the performance in every cognitive task. Post-stroke participants increased their dynamic stability in the frontal plane in single task by extending their base of support and mainly relying on their non-paretic limb. Under cognitive-motor interference (dual-task), post-stroke participants prioritized dynamic stability over cognitive performance to ensure a safe locomotion. Thus, rehabilitation programs should consider both dynamic balance and dual-task training, even at a chronic delay following stroke, to reduce the risk of fall in post-stroke individuals. PMID- 29448163 TI - Sperm DNA fragmentation: An early and reliable marker of air pollution. AB - Environmental factors could have a key role in the continuous and remarkable decline of sperm quality observed in the last decades. This study compared the seminal parameters and sperm DFI in men living in areas with different levels of air pollution. Results demonstrate that both steel plants workers and patients living in a high polluted area show a mean percentage of sperm DNA fragmentation above 30%, highlighting a clear sperm damage. In this work, two different techniques were used to measure sperm DNA damage in patients' groups, finding in both cases a high sperm DFI in patients living in polluted areas. We candidate sperm DNA fragmentation as a valuable early marker of the presence and harmful effects of pollution. We suggest that sperm DNA evaluation could be both an indicator of individual health and reproductive capacity, and a suitable datum to connect the surrounding environment with its effects. PMID- 29448164 TI - The toxicology of indium oxide. AB - Indium oxide (In2O3) is a technologically important semiconductor essentially used, doped with tin oxide, to form indium tin oxide (ITO). It is poorly soluble in all so far tested physiologic media. After repeated inhalation, In2O3 particles accumulate in the lungs. Their mobilization can cause significant systemic exposure over long periods of time. An increasing number of cases of severe lung effects (characterized by pulmonary alveolar proteinosis, emphysema and/or interstitial fibrosis) in workers of the ITO industry warrants a review of the toxicological hazards also of In2O3. The database on acute and chronic toxicity/carcinogenicity/genotoxicity/reproductive toxicity as well skin/eye irritation and sensitization is very limited or even lacking. Short-term and subchronic inhalation studies in rats and mice revealed persistent alveolar proteinosis, inflammation and early indicators of fibrosis in the lungs down to concentrations of 1 mg/m3. Epidemiological and medical surveillance studies, serum/blood indium levels in workers as well as data on the exposure to airborne indium concentrations indicate a need for measures to reduce exposure at In2O3 workplaces. PMID- 29448165 TI - 90Y radioembolization dosimetry using a simple semi-quantitative method in intrahepatic cholangiocarcinoma: Glass versus resin microspheres. AB - INTRODUCTION: There are two different types of 90Y Microspheres, glass and resin, in the market for 90Y radioembolization (90Y-RE). This study aimed to investigate the dose of radiation delivered through glass vs. resin-based 90Y-RE to intrahepatic cholangiocarcinoma (ICC). METHODS: In this retrospective study, 10 patients with ICC underwent 90Y-RE, five underwent glass (Glass group) and other 5 resin (Resin group) microspheres. Technetium-99m macro-aggregated albumin (Tc 99m MAA) shunt study was performed two weeks before 90Y-RE. Within 2 h from 90Y RE, Bremsstrahlung SPECT/CT was obtained. Regions of interest (ROIs) were segmented around the targeted tumor and the liver. Tumor and liver volumes, corresponding radioactive counts, and tumor to liver count ratio were calculated using MIM software and compared between Glass and Resin groups. RESULTS: Mean hepatopulmonary shunt fraction was 7.1 vs. 6.2% for the Glass and Resin groups (p = 0.83), with no extrahepatic activity. There was no difference in the activity and tumor uptake of administered Tc-99m MAA between both groups (p = 0.71 and p = 0.63). Mean administered activity of 90Y in the Glass group was higher than the Resin group (73.2 +/- 24.3 vs. 44.5 +/- 18.2 mCi, p < 0.001). The tumor 90Y uptake was significantly higher in the Glass group compared to the Resin group (41.3% vs. 33.5%, p < 0.001), corresponding to the mean tumor dose of 205.7 +/- 19.7 vs. 128.9 +/- 10.6 Gy, respectively (p < 0.001). The tumor to normal liver parenchyma 90Y dose ratio was significantly higher in the Glass group compared to the Resin group, 4.9 +/- 0.7 versus 2.4 +/- 0.3 respectably (p < 0.001). CONCLUSIONS: Both 90Y glass and resin-based microsphere 90Y-RE are feasible and safe in patients with ICC, while 90Y glass microsphere delivers higher dose of 90Y to the targeted tumors. ADVANCES IN KNOWLEDGE: While both 90Y glass and resin based microsphere yttrium-90 radioembolization are feasible and safe treatment options for in patients with intrahepatic cholangiocarcinoma, 90Y glass microsphere delivers higher dose of 90Y to the targeted tumors. IMPLICATIONS FOR PATIENT CARE: Both of 90Y glass and resin-based microsphere can be safely and feasibly used for treatment of intrahepatic cholangiocarcinoma, difference in dose of 90Y delivered to the targeted tumors should be clinically considered while choosing the microsphere type.

AB - Plasma lipid levels are heritable quantitative risk factors and therapeutic targets for cardiovascular disease. Plasma lipids have been a model for translating genetic observations across the allele frequency spectrum to unique biological and therapeutic insights. Most large studies to date predominately comprised of individuals of European ancestry. This review focuses on contemporary evidence from 2016 to 2017 looking at the effect of genetic variants on plasma lipid levels across the allele frequency spectrum with incrementally larger sample sizes and the contribution of non-European ancestry studies to the genetic etiology of plasma lipid levels. To date, over 250 loci have been associated with plasma lipid levels and several of these loci have additional evidence of association with rare coding variants providing evidence for causal genes at the locus. PMID- 29448167 TI - Development of graphite carbon nitride based fluorescent immune sensor for detection of alpha fetoprotein. AB - A novel fluorescent immunosensor for determination of alpha fetoprotein (AFP) in serum samples has been developed based on the nano graphite carbon nitride (g C3N4) as fluorophore and immunomagnetic beads (MBs) as separation material. The bulk g-C3N4 was obtained by thermal polymerization of melamine, and then carboxylated and exfoliated to acquire the carboxylated nano g-C3N4 (c-n-g-C3N4), which has been characterized and the results showed that it had excellent fluorescent properties. The antibodies of AFP (Ab1, Ab2) were conjugated to the MBs and the c-n-g-C3N4, respectively. In assay of AFP detection, the magnetic part of the immunosensor, MBs-Ab1, would form the sandwich type complex with the signal part of the sensor, c-n-g-C3N4-Ab2. The developed immunosensor could simplify the process of separation due to the MBs. The results illustrated that proposed approach held a good linearity between the fluorescence intensity of the sensor and the AFP concentration ranging from 5-600ng/mL with the limit of detection as low as 0.43ng/mL, and its spiking recoveries ranged from 98.2% to 105.9% with RSD from 2.1% to 3.5%. The fabricated fluorescent immunosensor possesses the merits of good sensitivity, excellent selectivity, high biocompatibility and low cost, and the results provide a novel clue to develop immunosensor for determination of the biomarkers in complex matrices. PMID- 29448168 TI - Simultaneous determination of Magnolol and Honokiol by amino acid ionic liquid synchronous fluorescence spectrometry. AB - A novel method based on amino acid ionic liquids (AAILs) as an additive synchronous fluorescence spectrometry is proposed for simultaneous determination of magnolol (MN) and honokiol (HN) in traditional Chinese medicine Houpu. The overlapping fluorescence spectrum of MN and HN could be completely separated in the AAILs medium. Experiment parameters (the type and concentration of AAILs, pH values and temperature) were discussed. The detection limits of MN and HN reached 1.46ng/mL, 0.92ng/mL and the recovery rates ranged from 98.6%-100.7%, 99.7% 100.6%, respectively. This methods was successfully employed for simultaneously determination of MN and HN in real samples. No significant differences could be found in the results of this method and the pharmacopoeia of People's Republic of China 2015 (Ch.P.2015). The experiment mechanisms were discussed by the Gaussian simulation and fluorescence quantum yield. PMID- 29448169 TI - Molecular spectroscopic features of protein in newly developed chickpea: Relationship with protein chemical profile and metabolism in the rumen and intestine of dairy cows. AB - The first aim of this study was to investigate the nutritional value of crude protein (CP) in CDC [Crop Development Centre (CDC), University of Saskatchewan] chickpea varieties (Frontier kabuli and Corinne desi) in comparison with a CDC barley variety in terms of: 1) CP chemical profile and subfractions; (2) in situ rumen degradation kinetics and intestinal digestibility of CP; 2) metabolizable protein (MP) supply to dairy cows; and (3) protein molecular structure characteristics using advanced molecular spectroscopy. The second aim was to quantify the relationship between protein molecular spectral characteristics and CP subfractions, in situ rumen CP degradation characteristics, intestinal digestibility of CP, and MP supply to dairy cows. Samples (n=4) of each variety, from two consecutive years were analyzed. Chickpeas had higher (P<0.01) CP content (21.71-22.11 vs 12.96% DM), with higher (P<0.05) soluble CP subfraction (59.07-70.27 vs 26.18% CP), and in situ soluble (23.44-25.85 vs 1.30% CP) and rumen degradable (RDP; 72.23-72.57 vs 58.48% CP) fractions than barley. The potentially slowly rumen degradable (D; 74.14-76.56 vs 93.31% CP) and undegradable (RUP; 27.43-27.66 vs 41.52% CP) fractions were lower (P<0.01) in the chickpeas than barley. The effective degradability ratio of N to organic matter (OM) (36.07-38.44gN/kg OM) of the chickpeas was higher than the optimal for achieving optimum microbial CP (MCP) synthesis. The truly digested MCP (64.94 66.43 vs. 41.43g/kg DM); MP (81.10-83.67 vs 61.0g/kg DM) feed milk value (1.64 1.70 vs 1.24) was higher in the chickpeas than barley grain. The chickpeas had higher (P<0.05) amide I and II peaks area and height, and alpha-helix and beta sheet peaks height than barley. Multivariate analysis showed that protein molecular spectral data of chickpeas can be distinguished from the barley. The two chickpeas did not differ in CP content, and any of the measured in situ degradation and molecular spectral characteristics of protein. The content of RUP was positively (r=0.94, P<0.01) and that of RDP was negatively (r=-0.94, P<0.01) correlated with amide I/II area ratio. The regression analysis showed that the content of CP (R2=0.91) D-fraction (R2=0.82), RDP (R2=0.77), RUP (R2=0.77), TDP (R2=0.98), MP (R2=0.80), and FMV (R2=0.80) can be predicted from amide II peak height. Despite extensive ruminal degradation, chickpea is a good source of MP for dairy cows, and molecular spectroscopy can be used to rapidly characterize feed protein molecular structures and predict their digestibility and nutritive value. PMID- 29448170 TI - Study of interaction between ionic liquids and orange G in aqueous solution with UV-vis spectroscopy and conductivity meter. AB - The interactions between Orange G (OG) with three kinds of ionic liquid surfactants (C10mimBF4, C12mimBF4, C16mimBF4) and CTAB were studied with UV-Vis spectra and conductivity measurements. The systematic changes in UV-Vis spectra with an increase of carbon-chain length may be observed in presence of OG. They correspond to CMC of every system, respectively, and the CMCs of four systems have exhibit the decrease of CMCs compared to pure surfactant. The binding constants are calculated from the results of conductivity measurements in the order of C16mimBF4>CTAB>C12mimBF4>C10mimBF4. Furthermore, system behaviors presented significant association of complex formation and micelles formation, i.e. the change in UV-Vis spectra before and after the formation of micelles in mixed systems. In addition, Fourier-transform infrared (FT-IR) spectroscopy and 1H NMR analysis further confirmed that the complexes are formed by hydrogen bond and van der Waal force. These findings could provide scientific guidance for extraction and separation of dyes. PMID- 29448171 TI - Evaluation of the effect of polymorphism on G-quadruplex-ligand interaction by means of spectroscopic and chromatographic techniques. AB - Guanine-rich sequences may fold into highly ordered structures known as G quadruplexes. Apart from the monomeric G-quadruplex, these sequences may form multimeric structures that are not usually considered when studying interaction with ligands. This work studies the interaction of a ligand, crystal violet, with three guanine-rich DNA sequences with the capacity to form multimeric structures. These sequences correspond to short stretches found near the promoter regions of c-kit and SMARCA4 genes. Instrumental techniques (circular dichroism, molecular fluorescence, size-exclusion chromatography and electrospray ionization mass spectrometry) and multivariate data analysis were used for this purpose. The polymorphism of G-quadruplexes was characterized prior to the interaction studies. The ligand was shown to interact preferentially with the monomeric G quadruplex; the binding stoichiometry was 1:1 and the binding constant was in the order of 105M-1 for all three sequences. The results highlight the importance of DNA treatment prior to interaction studies. PMID- 29448172 TI - Analysis of quetiapine in human plasma using fluorescence spectroscopy. AB - A simple and sensitive spectrofluorimetric method has been development for the assurance of quetiapine fumarate (QTF). The proposed method was utilized for measuring the fluorescence intensity of the yellow fluorescent product at 510nm (lambdaex 470nm). The fluorescent product has resulted from the nucleophilic substitution reaction of QTF with 4-chloro-7-nitrobenzofurazane (NBD-Cl) in Mcllvaine buffer (pH7.0). The diverse variables influencing the development of the reaction product were deliberately changed and optimized. The linear concentration range of the proposed method was of 0.2-2.0MUgml-1.The limits of detection and quantitation were 0.05 and 0.17MUgml-1, respectively. The proposed method was applied for the assurance of QTF in its tablets without interference from basic excipients. In addition, the proposed method was used for in vitro analysis of the QTF in spiked human plasma, the percent mean recovery was (n=3) 98.82+/-1.484%. PMID- 29448173 TI - Enhancement of UVB-induced DNA damage repair after a chronic low-dose UVB pre stimulation. AB - Absorption of solar ultraviolet (UV) radiation by DNA leads to the formation of the highly mutagenic cyclobutane pyrimidine dimer (CPD). The mutagenicity of CPD is caused, in part, by the fact that their recognition and repair by the nucleotide excision repair (NER) pathway is challenging and slow. It has been previously shown that a pre-stimulation with genotoxic agents improve NER efficiency of CPD, indicating a potential adaptive response of this repair pathway. We have pre-treated human dermal fibroblasts with repeated subletal low doses of UVB (chronic low-dose of UVB; CLUV) to determine whether it could enhance NER capacity to repair CPD. Our results show that CLUV pre-treatment greatly enhances CPD repair but have little effect on the repair of another UV induced bypirimidine photoproduct, the pyrimidine (6-4) pyrimidone photoproducts (6-4 PP). We have determined that the CLUV treatment activates p53 and we found an increase of DDB2 and XPC gene expression. This is consistent with an increasing level of NER recognition proteins, DDB2 and XPC, we found concentrated at the chromatin. This study represents the first demonstration that chronic UVB exposure can stimulate NER pathway. Altogether, these results shed light on the potential adaptability of the NER by chronic UVB irradiation and the mechanisms involved. PMID- 29448174 TI - Extracellular vesicles - new players in cell-cell communication in aquatic environments. AB - Communication between microorganisms in aquatic environments can influence ecosystem function and determine the structure and composition of microbial populations. This microbial cross talk can be mediated by excretion of specialized metabolites or extracellular vesicles (EVs). Recently it has become apparent that cells across all domains of life produce EVs that may convey specific targeted signals that can modulate cell fate, morphology and susceptibility to viruses. The vast majority of knowledge about EVs is derived from studies of mammalian tissues, parasitic host-pathogen interactions and model bacterial systems. Very little is known about the role of EVs in aquatic environments, although they have potential to influence community structure and trophic-level interactions. We propose functions and ecological implications of communication via EVs in aquatic microbial ecosystems. PMID- 29448175 TI - Metals in mangrove ecosystems and associated biota: A global perspective. AB - Mangrove forests prevalent along the intertidal regions of tropical and sub tropical coastlines are inimitable and dynamic ecosystems. They protect and stabilize coastal areas from deleterious consequences of natural disasters such as hurricanes and tsunamis. Although there are reviews on ecological aspects, industrial uses of mangrove-associated microorganisms and occurrence of pollutants in a region-specific manner, there is no exclusive review detailing the incidence of metals in mangrove sediments and associated biota in these ecosystems on a global level. In this review, mangrove forests have been classified in a continent-wise manner. Most of the investigations detail the distribution of metals such as zinc, chromium, arsenic, copper, cobalt, manganese, nickel, lead and mercury although in some cases levels of vanadium, strontium, zirconium and uranium have also been studied. Seasonal, tidal, marine, riverine, and terrestrial components are seen to influence occurrence, speciation, bioavailability and fate of metals in these ecosystems. In most of the cases, associated plants and animals also accumulate metals to different extents and are of ecotoxicological relevance. Levels of metals vary in a region specific manner and there is disparity in the pollution status of different mangrove areas. Protecting these vulnerable ecosystems from metal pollutants is important from environmental safety point of view. PMID- 29448176 TI - Mechanisms of phloem loading. AB - The complex form of higher plants requires continuous, balanced transport of nutrients in the phloem. The initial step of transferring sugars, amino acids, and other materials from photosynthetic cells to the conducting sieve tubes is known as phloem loading. Three phloem loading mechanisms have been described. The first involves release of sucrose into the apoplast and subsequent retrieval by the phloem. The initial release step in this process is now known to be mediated by a new class of transporters, the SWEET proteins. In the other two loading mechanisms, polymer trapping and diffusion, sucrose passes into the phloem through cytoplasmic channels, the plasmodesmata. Recent models have shed additional light on these mechanisms and their ability to sustain the growth of even the tallest trees. PMID- 29448177 TI - Drought impacts on phloem transport. AB - Drought impacts on phloem transport have attracted attention only recently, despite the well-established, and empirically verified theories on drought impacts on water transport in plants in general. This is because studying phloem transport is challenging. Phloem tissue is relatively small and delicate, and it has often been assumed not to be impacted by drought, or having insignificant impact on plant function or survival compared to the xylem. New evidence, however, suggests that drought responses of the phloem might hold the key for predicting plant survival time during drought or revival capacity after drought. This review summarizes current theories and empirical evidence on how drought might impact phloem transport, and evaluates these findings in relation to plant survival during drought. PMID- 29448178 TI - Modification of the association between antipsychotic treatment response and childhood adversity by MMP9 gene variants in a first-episode schizophrenia cohort. AB - Antipsychotics remain the most effective, and wide used option for ameliorating the symptoms of schizophrenia. However, inter-individual differences in treatment outcome are vast and suggest a role for genetic and environmental factors in affording favourable outcomes. A notable epigenetic relationship which has gained considerable traction in recent literature is the way in which the severity of childhood trauma can modify associations seen between genetic variation and antipsychotic treatment response. A potential mechanism of action which may facilitate this relationship is synaptic plasticity. This study investigated the role of variants in matrix metallopeptidase 9 (MMP9), a gene involved in synaptic plasticity, with treatment outcome considering the severity of childhood trauma as an interacting variable. The cohort comprised South African first episode schizophrenia patients treated with a single injectable antipsychotic, flupenthixol decanoate, monitored over 12 months. Relationships between novel and previously described variants, and haplotypes, with antipsychotic treatment response were found to be modified when considering childhood trauma as an interacting variable. This study provides the first evidence for the involvement of polymorphisms within MMP9 and the severity of childhood trauma in antipsychotic treatment response, and warrants further investigation into the role gene-environment interactions may play in the betterment of antipsychotic treatment strategies. PMID- 29448179 TI - Elevated neutrophil to lymphocyte ratio in non-affective psychotic adolescent inpatients: Evidence for early association between inflammation and psychosis. AB - Accumulating data suggest an association between inflammation and schizophrenia and related psychosis. While several studies have established this immune psychosis association in adult schizophrenia patients, there is very limited data associating inflammation with acute psychosis in children and adolescents. The ratio between neutrophils and lymphocyte, computed from routine blood counts, has been shown to correlate with traditional markers of inflammation, and is therefore considered a proxy-marker for inflammation. Here we report elevated neutrophil to lymphocyte ratio and total leukocyte count in psychotic adolescent inpatients (n = 81, mean age 14.7 years, 52% males) compared to non-psychotic adolescent inpatient (n = 285, mean age 15.9 years, 58% males), in a population of adolescent inpatients with no affective symptomatology. The elevated neutrophil to lymphocyte ratio remained significant after controlling for confounders such as age, BMI, smoking and antipsychotic medication. In a subset of psychotic adolescent inpatients (n = 20, mean duration between blood test 157 days), we found significant decrease in neutrophil to lymphocyte ratio at clinical remission compared with the acute psychotic state. The results suggest that psychosis is associated with peripheral markers of inflammation early in the course of psychiatric pathology, and that inflammation may represent a state that accompanies psychosis and decreases during clinical remission. PMID- 29448180 TI - Feasibility of four wastes to remove heavy metals from contaminated soils. AB - Soil washing is one of the permanent techniques to remove heavy metals, and washing agent is a key influence factor for this technique, but there is still lack of high-efficiency, eco-friendly, and inexpensive agents. In this study, four wastes including pineapple peel (PP), soybean straw (SS), broad bean straw (BBS) and tea residue (TR) were employed to remove cadmium (Cd), lead (Pb) and zinc (Zn) in contaminated soils. The Fourier transform infrared spectroscopy (FTIR) analysis indicated that hydroxyl, carboxyl, amine, carbonyl and amide groups were involved in the interaction with metal ions by complexation or ion exchange. We then investigated the influences of various conditions including washing solution concentration, pH, and washing time. The metal removal efficiencies with these agents increased as the concentration augmented from 5 to 80 g L-1, decreased or presented an asymmetric V-shaped curve with increasing pH from 2.5 to 7.5, and fit intraparticle diffusion or Elovich model with washing time increasing. PP has the highest removals for Cd (90.1%), Pb (18.6%), and Zn (15.2%) in soil A, and 85.8, 24.8, and 69.4% in soil B, respectively. The relatively high metal removal was mainly attributed to effective removal of the exchangeable and acid soluble fractions. Moreover, single washing not only lowered the potential ecological risk of the heavy metals, but moderated the effects on soil chemical properties. Therefore, PP was a feasible washing agent to remediate soils contaminated by heavy metals. PMID- 29448181 TI - Effect of beach management policies on recreational water quality. AB - When beach water monitoring programs identify poor water quality, the causes are frequently unknown. We hypothesize that management policies play an important role in the frequency of fecal indicator bacteria (FIB) exceedances (enterococci and fecal coliform) at recreational beaches. To test this hypothesis we implemented an innovative approach utilizing large amounts of monitoring data (n > 150,000 measurements per FIB) to determine associations between the frequency of contaminant exceedances and beach management practices. The large FIB database was augmented with results from a survey designed to assess management policies for 316 beaches throughout the state of Florida. The FIB and survey data were analyzed using t-tests, ANOVA, factor analysis, and linear regression. Results show that beach geomorphology (beach type) was highly associated with exceedance of regulatory standards. Low enterococci exceedances were associated with open coast beaches (n = 211) that have sparse human densities, no homeless populations, low densities of dogs and birds, bird management policies, low densities of seaweed, beach renourishment, charge access fees, employ lifeguards, without nearby marinas, and those that manage storm water. Factor analysis and a linear regression confirmed beach type as the predominant factor with secondary influences from grooming activities (including seaweed densities and beach renourishment) and beach access (including charging fees, employing lifeguards, and without nearby marinas). Our results were observable primarily because of the very large public FIB database available for analyses; similar approaches can be adopted at other beaches. The findings of this research have important policy implications because the selected beach management practices that were associated with low levels of FIB can be implemented in other parts of the US and around the world to improve recreational beach water quality. PMID- 29448182 TI - Enhanced alumina recovery from secondary aluminum dross for high purity nanostructured gamma-alumina powder production: Kinetic study. AB - The numerous ecological problems caused by the accumulation of secondary aluminum dross (SAD) as a hazardous waste generated in aluminum castings have necessitated a need for a sustainable recycling solution. This study proposes a novel and green leaching-based process for recovery of nano-alumina as a highly valuable material from SAD. The leaching phase was performed at atmospheric pressure and low temperature. To obtain optimum conditions for the recovery process, the dissolution kinetics and mechanism of SAD in hydrochloric acid were initially studied under a given liquid-to-solid ratio of 20 ml/g, various reaction temperatures and times. It was found that the dissolution of SAD in HCl was controlled by layer diffusion with an apparent activation energy of around 10.49 kJ/mol. Alumina in the form of a high purity nanostructured powder from SAD was then recovered under optimum conditions of 85 degrees C, acid concentration of 5 mol/l, and reaction time of 120 min by the proposed process. Characterization of nano-alumina was performed using X-ray diffractometry (XRD), Fourier transform infrared (FTIR) spectroscopy, field emission scanning electron microscopy (FESEM), energy-dispersive X-ray spectroscopy (EDAX), and transmission electron microscopy (TEM) techniques. The results revealed that the as-produced alumina had a nano-crystalline structure, having the crystal size of 15.90 nm and consisting mainly of gamma phase. The microstructural studies disclosed the aggregations of rounded-corner shaped particles. Also, wet chemical analysis showed a purity of more than 98% for the produced alumina. PMID- 29448183 TI - Change in metals and arsenic distribution in soil and their bioavailability beside old tailing ponds. AB - The objectives of this study were to determine the metals and arsenic transfer from mining ponds to agricultural and forest soils, and identify the dynamic of metal(loid)s in the soil-plant system for a native plant species (Ballota hirsuta) in two old mining districts: La Union and Mazarron (Spain). Soils and plants from mining ponds and natural and agricultural areas were collected and analyzed for soil properties, and chemical partitioning of Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Zn and As. Results showed that mine, forest and agricultural soils were contaminated by As, Cd, Cu, Pb, and Zn. Chemical partitioning revealed higher mobility of metals in mining ponds than natural and agricultural soils except for Fe and As which were mostly bound to soil matrix due to the mineralogical compositions of soils. The accumulation of metal(loid)s in B. hirsuta in La Union decreased as Fe > As > Cr > Ni > Cu > Zn > Cd > Mn > Co > Pb while in Mazarron was As > Fe > Cr > Pb > Cu > Ni > Co > Mn > Zn > Cd, showing that B. hirsuta has high ability to bio-accumulate Fe, As, Cr, Cu and Ni; and Pb (in Mazarron), transferring a significant concentration of theses metal(loid)s, except Pb, to edible parts without exceeding the toxicity limits for animals. Therefore, B. hirsuta could be useful as phytoextractor species for Cr, Cu, As and Ni, while it can be used as phytostabilizer species for Zn, Co, Pb and Cd. PMID- 29448184 TI - Spontaneous alveolar bone loss after 4NQO exposure in Wistar rats. AB - OBJECTIVE: This study evaluated the effect of an experimental carcinogenic, 4 Nitroquinoline 1-oxide (4NQO), in the spontaneous alveolar bone loss (ABL) in an animal model. DESIGN: Twenty-two male Wistar rats were included in this study. They were randomly divided into two groups: the control group (n = 10) received food and water ad libitum, and the test group (n = 12) receive the same food; however, 25 ppm of 4NQO was diluted in the drinking water. All animals were euthanized after 20 weeks, and the tongues were removed and analyzed macroscopically to determine the presence of oral mucosal lesions. All specimens were paraffin-embedded and histological sections were obtained. The microscopic analysis was based on routine procedure (haematoxylin and eosin stain). The analysis of spontaneous ABL was performed by a calibrated examiner using standardized photographs and imaging software. Differences in spontaneous ABL were assessed among the three resulting groups: control, 4NQO with oral squamous cell carcinoma (OSCC), and 4NQO without OSCC. RESULTS: In the 4NQO-treated group, nine animals developed OSCC. The animals in the 4NQO with OSCC group presented significantly more spontaneous ABL (0.65 +/- 0.21 mm) than the control group (0.34 +/- 0.05) (p < 0.001). The animals in the 4NQO without OSCC group showed a mean spontaneous ABL of 0.47 +/- 0.13 mm, which was not statistically significant different when compared to the control group (p = 0.096). CONCLUSIONS: It was concluded that the presence of OSCC enhanced spontaneous ABL in Wistar rats when compared to control animals. Additionally, it was shown that, solely, administration of 4NQO may not be considered responsible for alveolar bone destruction. PMID- 29448185 TI - The effect of parental style on bullying and cyber bullying behaviors and the mediating role of peer attachment relationships: A longitudinal study. AB - The purpose of the present study was the examination of the longitudinal effect of parental style on short-term changes in conventional and cyber forms of bullying/victimization, and the investigation of the mediating role of peer attachment relationships on this effect. The participants were 861 children and adolescents (52% girls, Mage = 11.72 years) attending Cyprus public institutions. Students provided information during three measurement points. There was a six and a 12 week interval among the three measurement points, respectively. The findings of the study indicated that parenting seems to be a significant predictor of all forms of bullying/victimization, conventional and cyber, in early adolescents, even when accounting for bullying/victimization levels eighteen weeks back. More importantly, results showed that the effect of parental style on bullying forms was mediated by peer attachment relationships. Results are discussed in the light of theoretical and practical implications. PMID- 29448186 TI - Cognitive development in children of adolescent mothers: The impact of socioeconomic risk and maternal sensitivity. AB - BACKGROUND: Adolescent motherhood is accompanied by a constellation of risk factors that translate into developmental risk for the off-spring. Socioeconomic risk that is associated with adolescent motherhood as well as maternal interactive behaviors may contribute to the impact of adolescent motherhood on children's developmental outcome. OBJECTIVE: Therefore, the aim of the current study was to investigate differences in children's cognitive development between children of adolescent and adult mothers in their first two years of life and to examine whether socioeconomic risk (e.g. such as educational and financial problems) and/or maternal sensitivity mediate developmental differences between children of adolescent and adult mothers. METHODS: Adolescent mothers (<21 years; N = 64) and adult mothers (>25 years; N = 34) and their infants were included in the current study. Child cognitive development and maternal sensitivity were assessed at three different time points (T1: mean child age 5.26 months; T2: mean child age 14.69 months; T3: mean child age 21.16 months). RESULTS: Children of adult mothers showed better cognitive performance at T3 compared to children of adolescent mothers but not at T1 and T2. A multiple mediation model including socioeconomic risk and maternal sensitivity as serial mediators demonstrated that the effect of adolescent motherhood on cognitive development was mediated in a causal effect chain with socioeconomic risk negatively affecting maternal sensitivity and maternal sensitivity affecting children's cognitive development. DISCUSSION: The present findings demonstrate that maternal interactive behaviors are not only a simple predictor of cognitive development but may also act as a mediator of the association between more distal variables such as socioeconomic risk and cognitive development in adolescent mothers. This supports the need to promote prevention and intervention programs for adolescent mothers during the early postpartum period to reduce socioeconomic problems and enhance maternal interactive behaviors. PMID- 29448187 TI - Development of the Drooling Infants and Preschoolers Scale (DRIPS) and reference charts for monitoring saliva control in children aged 0-4 years. AB - OBJECTIVES: To develop and validate a parent questionnaire to quantify drooling severity and frequency in young children (the Drooling Infants and Preschoolers Scale - the DRIPS). To investigate development of saliva control in typically developing young children in the age of 0-4 years. To construct sex-specific reference charts presenting percentile curves for drooling plotted for age to monitor the development of saliva control in infancy and preschool age. STUDY DESIGN: The DRIPS was developed consisting of 20 items to identify severity and frequency of drooling during meaningful daily activities. Factor analysis was performed to test construct validity. A piecewise logistic regression was followed by a piecewise linear regression to construct sex-specific reference charts. RESULTS: We obtained 652 completed questionnaires from parents of typically developing children. The factor analysis revealed four discriminating components: drooling during Activities, Feeding, Non nutritive sucking, and Sleep. To illustrate the development of saliva control, eight sex-specific reference curves were constructed to plot the scores of the DRIPS by age group, at the 15th, 50th, 85th and 97th percentile. About 3-15% of the preschoolers in our cohort did not acquire full saliva control at the age of 4 years. CONCLUSIONS: With the DRIPS it is possible to validly compare and visualize the development of saliva control in an individual infant or preschooler and allow clinicians to timely initiate individually targeted interventions if children outperform. PMID- 29448188 TI - Genotype, phenotype and in silico pathogenicity analysis of HEXB mutations: Panel based sequencing for differential diagnosis of gangliosidosis. AB - OBJECTIVES: Gangliosidosis is an inherited metabolic disorder causing neurodegeneration and motor regression. Preventive diagnosis is the first choice for the affected families due to lack of straightforward therapy. Genetic studies could confirm the diagnosis and help families for carrier screening and prenatal diagnosis. An update of HEXB gene variants concerning genotype, phenotype and in silico analysis are presented. PATIENTS AND METHODS: Panel based next generation sequencing and direct sequencing of four cases were performed to confirm the clinical diagnosis and for reproductive planning. Bioinformatic analyses of the HEXB mutation database were also performed. RESULTS: Direct sequencing of HEXA and HEXB genes showed recurrent homozygous variants at c.509G>A (p.Arg170Gln) and c.850C>T (p.Arg284Ter), respectively. A novel variant at c.416T>A (p.Leu139Gln) was identified in the GLB1 gene. Panel based next generation sequencing was performed for an undiagnosed patient which showed a novel mutation at c.1602C>A (p.Cys534Ter) of HEXB gene. Bioinformatic analysis of the HEXB mutation database showed 97% consistency of in silico genotype analysis with the phenotype. Bioinformatic analysis of the novel variants predicted to be disease causing. In silico structural and functional analysis of the novel variants showed structural effect of HEXB and functional effect of GLB1 variants which would provide fast analysis of novel variants. CONCLUSIONS: Panel based studies could be performed for overlapping symptomatic patients. Consequently, genetic testing would help affected families for patients' management, carrier detection, and family planning's. PMID- 29448189 TI - 3-(E)-Styryl-2H-chromene derivatives as potent and selective monoamine oxidase B inhibitors. AB - A series of novel 3-(E)-styryl-2H-chromene derivatives were synthesized and their monoamine oxidase (MAO) A and B inhibitory activities were evaluated. All compounds exhibited no inhibitory activity towards MAO-A at 10 MUM whereas compounds 1-5, 7, 9, 11-13, 15 and 16 showed strong inhibitory activity towards MAO-B at this concentration. Of these, compound 3, which contains fluorine at R3, showed the highest activity (IC50 = 10 nM), and is about 22-fold more potent than pargyline (used as a positive control). Quantitative structure-activity relationship (QSAR) analyses of 3-(E)-styryl-2H-chromene derivatives were conducted using Molecular Operating Environment (MOE). QSAR analyses of 3-(E) styryl-2H-chromene derivatives with pIC50 values for MAO-B demonstrated that 140 descriptors showed significant correlations. The strongly correlated descriptors indicated that properties such as molecular shape, size, and hydrophobicity, as well as the functional groups, of 3-(E)-styryl-2H-chromene derivatives are important for their inhibitory activity. This is the first report identifying 3 (E)-styryl-2H-chromene derivatives as potent and selective MAO-B inhibitors. These results suggest that the 3-(E)-styryl-2H-chromene structure may be a useful scaffold for the design and development of novel monoamine oxidase inhibitors.

AB - Recent studies have shown the efficiency of hydroxyl radicals generated via ultraviolet (UV)-based advanced oxidation processes (AOPs) combined with hydrogen peroxide (UV/H2O2) as a treatment process in water. The effects of AOP treatments on bacterial gene expression was examined using Pseudomonas aeruginosa strain PAO1 as a model-organism bacterium. Many bacterial genes are not expressed all the time, but their expression is regulated. The regulation is at the beginning of the gene, in a genetic region called "promoter" and affects the level of transcription (synthesis of messenger RNA) and translation (synthesis of protein). The level of expression of the regulated genes can change as a function of environmental conditions, and they can be expressed more (induced, upregulated) or less (downregulated). Exposure of strain PAO1 to UV/H2O2 treatment resulted in a major change in gene expression, including elevated expression of several genes. One interesting gene is PA3237, which was significantly upregulated under UV/H2O2 as compared to UV or H2O2 treatments alone. The induction of this gene is probably due to formation of radicals, as it is abolished in the presence of the radical scavenger tert-butanol (TBA) and is seen even when the bacteria are added after the treatment (post-treatment exposure). Upregulation of the PA3237 promoter could also be detected using a reporter gene, suggesting the use of such genetic constructs to develop biosensors for monitoring AOPs in water-treatment plants. Currently biosensors for AOPs do not exist, consequently impairing the ability to monitor these processes on-line according to radical exposure in natural waters.

Towards the development of a cost effective technology for the treatment of wastewater. AB - A novel arrangement for an electro-Fenton reactor aimed to treat neutral wastewater is presented. The arrangement consists on three-compartments in series, two of them packed with a cation exchange resin and one positioned between these, containing a polarized activated carbon column where the electrochemical generation of the Fenton reagent takes place. While the hydroxyl radicals electrochemically produced in-situ, react with the pollutant species adsorbed on the activated carbon cathode, the resin compartments administrate and collect the iron cation and the hydrated proton species in alternating flow direction cycles. The resulting process is a system that does not require acid or iron chemical addition to the process while at the same time, renders decontaminated water free of iron-dissolved species at neutral pH. The proposed electrochemical reactor arrangement is therefore the basis for the design of commercially viable electro-Fenton reactors in which the addition and subsequent removal of acid and iron chemicals is avoided; two of the currently most limiting features for the development of electro-Fenton technology for treating wastewater. PMID- 29448192 TI - Impact of enzymatic hydrolysis on the quantification of total urinary concentrations of chemical biomarkers. AB - Human exposure to consumer and personal care products chemicals such as phenols, including parabens and other antimicrobial agents, can be assessed through biomonitoring by quantifying urinary concentrations of the parent chemical or its metabolites, often after hydrolysis of phase II conjugates. Developing suitable analytical methods for the concurrent quantification of multiple exposure biomarkers is challenging because optimal conditions for the hydrolysis of such conjugates (e.g., O-glucuronides, N-glucuronides, sulfates) may differ depending on the biomarker. We evaluated the effectiveness of seven commercial hydrolytic enzymes to simultaneously hydrolyze N-glucuronides (using the antibacterial triclocarban as example compound) and other conjugates (using select phenols and parabens as examples) by using on-line solid phase extraction-high performance liquid chromatography-isotope dilution-tandem mass spectrometry. Incubation (30 min, 55 degrees C) with a genetically engineered beta-glucuronidase (IMCS, >=15 units/MUL urine) hydrolyzed N-glucuronide triclocarban, but did not fully hydrolyze the conjugates of phenols and parabens. By contrast, incubation (4 h, 37 degrees C) with solid beta-glucuronidase (Helix pomatia, Type H-1, >=30 units/MUL urine) or liquid beta-glucuronidase/arylsulfatase (Helix pomatia, 30 units/MUL urine [i.e., 30 MUL/100 MUL urine]) in the presence of 100 MUL methanol for 100 MUL urine completely hydrolyzed N-glucuronide triclocarban and the conjugates of several phenols and parabens, without cleaving the ester bond of the parabens to form p-hydroxybenzoic acid. These results highlight the relevance of method validation procedures that include optimizing the hydrolysis of phase II urinary conjugates (e.g., enzyme type and amount used, reaction time, temperature) to quantify accurately and concurrently multiple exposure biomarkers for biomonitoring purposes. PMID- 29448193 TI - Influence of chloride on the 185 nm advanced oxidation process. AB - The use of 185 nm radiation from a conventional low pressure mercury lamp generates the hydroxyl radical (OH) from the photolysis of water and offers an advanced oxidation process (AOP) for water treatment that does not require chemical addition. However, the influence of the water matrix on the process differs substantially from that of other ultraviolet and ozone based processes. In particular chloride (Cl-), and not water, absorbs the majority of 185 nm photons when [Cl-]>20mgL-1 and generates the chlorine atom radical (Cl) as a reactive species. Evidence suggests that when Cl- is present, Cl and OH both contribute to contaminant degradation to varying extents. Using nonselective (carbamazepine) and selective (nitrobenzene) radical probes, as well as nonselective (t-butanol), and selective (acetone and acetate) radical scavengers, the influence of Cl-, and therefore 185 nm AOP treatment efficiency, is observed to strongly depend on four independent second-order radical rate constants. Furthermore, ionic strength effects support the assumption that Cl is in equilibrium with the relatively nonreactive dichlorine radical anion ().

AB - The Iberian Pyrite Belt (IPB), in the southwest of Europe, is characterized by high levels of contamination by acid mine drainage (AMD) in a large extent of its river network. In this scenario, it is necessary to characterize the degree of pollution of the mining leachates in the AMD-generating sources as well as of the main receiving watercourses. A map of impact of each basin was developed, based on the model proposed by Grande (2011) and the European Directive 98/83/EC that defines the quality standards for drinking water. The results indicate that practically all the mining leachates exceeded the maximum concentrations established by Directive 98/83/CE for Fe and Cd, almost 90% exceeded the limit for Mn and 82% for Al. Likewise, Fe, Cd, and Mn caused 'extremely high' degradation in most sampled leachates. Similarly, these metals, in addition to Pb, produced more pollution in watercourses located downstream of exploitations. PMID- 29448195 TI - Factors affecting the 7Be surface concentration and its extremely high occurrences over the Scandinavian Peninsula during autumn and winter. AB - Relationships between the beryllium-7 activity concentrations in surface air and meteorological parameters (temperature, atmospheric pressure, and precipitation), teleconnection indices (Arctic Oscillation, North Atlantic Oscillation, and Scandinavian pattern) and number of sunspots are investigated using two multivariate statistical techniques: hierarchical cluster and factor analysis. The beryllium-7 surface measurements over 1995-2011, at four sampling sites located in the Scandinavian Peninsula, are obtained from the Radioactivity Environmental Monitoring Database. In all sites, the statistical analyses show that the beryllium-7 concentrations are strongly linked to temperature. Although the beryllium-7 surface concentration exhibits the well-characterised spring/summer maximum, our study shows that extremely high beryllium-7 concentrations, defined as the values exceeding the 90th percentile in the data records for each site, also occur over the October-March period. Two types of autumn/winter extremes are distinguished: type-1 when the number of extremes in a given month is less than three, and type-2 when at least three extremes occur in a month. Factor analysis performed for these autumn/winter events shows a weaker effect of temperature and a stronger impact of the transport and production signal on the beryllium-7 concentrations. Further, the majority of the type-2 extremes are associated with a very high monthly Scandinavian teleconnection index. The type-2 extremes that occurred in January, February and March are also linked to sudden stratospheric warmings of the Arctic vortex. Our results indicate that the Scandinavian teleconnection index might be a good indicator of the meteorological conditions facilitating extremely high beryllium-7 surface concentrations over Scandinavia during autumn and winter. PMID- 29448196 TI - Bisphenol S induces obesogenic effects through deregulating lipid metabolism in zebrafish (Danio rerio) larvae. AB - It has been suggested that dramatic increase in obesity may be caused by growing exposure to environmental chemicals. In vitro data has suggested bisphenol S (BPS), a compound widely used in polycarbonate plastic production, can induce lipid accumulation in preadipocytes. However, the mechanisms responsible for BPS induced obesity in vivo remain unclear. In this study, we used translucent zebrafish (Danio rerio) larvae as a model to investigate the effect of environmentally relevant BPS exposure (1, 10, and 100 MUg/L from 2 h to 15 d post fertilization) on lipid accumulation, triacylglycerol (TAG) and lipoproteins content, and mRNA expression of genes involved in the regulation of lipid synthesis, transport, degradation, and storage. We also analyzed activities of two enzymes critical to TAG metabolism: lipoprotein lipase and diglyceride acyltransferase. Overfed, obese larvae were used as positive control. The results indicated that BPS-treated and overfed larvae had much higher TAG levels and visceral fat accumulation compared with control. BPS exhibited obesogenic effects by interfering with lipid metabolism as evidenced by (a) upregulation of the mRNA expression of fasn, acc1, and agpat4 genes encoding enzymes involved in the de novo synthesis of TAG in the liver, (b) downregulation of apolipoprotein expression, which should reduce TAG transport from the liver, and (c) increase in rxralpha expression, which should promote visceral fat accumulation. Our study is the first to demonstrate that the obesogenic effects of BPS in zebrafish are related to the disruption of TAG metabolism. PMID- 29448197 TI - PI3K/AKT signaling pathway involvement in fluoride-induced apoptosis in C2C12 cells. AB - To investigate the mechanisms of fluoride-induced apoptosis, a fluoride-induced C2C12 skeletal muscle cell (C2C12 cell) model was established in this study, and the viability of the C2C12 cells was measured using an MTT assay. Cell morphological changes were observed via haematoxylin and eosin staining and transmission electron microscopy. Apoptosis was monitored through Hoechst staining. The mRNA and protein expression of PI3K, PDK1, AKT1, BAD, Bcl-2, Bax and caspase-9 were detected through real-time PCR and western blotting, respectively. The results showed that the survival rates of C2C12 cells decreased gradually with an increasing fluoride doses. The C2C12 cell structure was seriously damaged by fluoride, presenting with pyknosis, mitochondrial ridge disruption and swollen endoplasmic reticulum. Furthermore, the expression of mRNA in PI3K, BAD, Bcl-2, Bax and caspase-9 were significantly increased in the fluoride group (P < 0.01), while the expression of PDK1 was markedly decreased (P < 0.01). The expression of protein in BAD, Bcl-2 and Bax were significantly increased in the fluoride group (P < 0.01), while the expression of PDK1 and P AKT1 was markedly decreased (P < 0.01). In conclusion, fluoride-induced apoptosis in C2C12 cells is related to the PI3K/AKT signaling pathway.

AB - Gardening and urban food production is an increasingly popular activity, which can improve physical and mental health and provide low cost nutritious food. However, the legacy of contamination from industrial and diffuse sources may have rendered surface soils in some urban gardens to have metals value in excess of recommended guidelines for agricultural production. The objective of this study was to establish the presence and spatial extent of soil metal contamination in Melbourne's residential and inner city community gardens. A secondary objective was to assess whether soil lead (Pb) concentrations in residential vegetable gardens were associated with the age of the home or the presence or absence of paint. The results indicate that most samples in residential and community gardens were generally below the Australian residential guidelines for all tested metals except Pb. Mean soil Pb concentrations exceeded the Australian HIL-A residential guideline of 300 mg/kg in 8% of 13 community garden beds and 21% of the 136 residential vegetable gardens assessed. Mean and median soil Pb concentrations for residential vegetable gardens was 204 mg/kg and 104 mg/kg (range <4-3341 mg/kg), respectively. Mean and median soil Pb concentration for community vegetable garden beds was 102 mg/kg and 38 mg/kg (range = 17-578 mg/kg), respectively. Soil Pb concentrations were higher in homes with painted exteriors (p = 0.004); generally increased with age of the home (p = 0.000); and were higher beneath the household dripline than in vegetable garden beds (p = 0.040). In certain circumstances, the data indicates that elevated soil Pb concentrations could present a potential health hazard in a portion of inner-city residential vegetable gardens in Melbourne. PMID- 29448199 TI - Insights on the criteria of selection of vegetable and mineral dielectric fluids used in power transformers on the basis of their biodegradability and toxicity assessments. AB - Leakage of transformer dielectric fluids is a concern because it may pose a risk of environmental contamination. In this study, the deleterious effects of vegetable and mineral dielectric fluids in water bodies were investigated using biodegradability and acute toxicity tests with Danio rerio and Artemia salina. Regarding biodegradability, all four tested vegetable oils (soy, canola, sunflower and crambe) were considered as easily biodegradable, presenting degradation rates significantly higher than the Lubrax-type mineral fluid. Acute toxicity tests were performed in two separate experiments without solution renewal. In the first experiment, the organisms were exposed in direct contact to different concentrations of vegetable (soy) and mineral (Lubrax) oils. Total soy type vegetable oil has a higher toxic effect than Lubrax-type mineral oil. In the second experiment, the organisms were exposed to increasing percentages of the water-soluble fraction (WSF) of both types of tested oils. The LC50 values for the water-soluble fraction of the Lubrax-type mineral oil were about 5 and 8% for the Danio rerio and Artemia salina bioindicators, respectively, whereas the vegetable oil did not present toxic effect, regardless of its WSF. These results have shown that a strict selection of dielectric fluids and monitoring the leakage from power transformers is a serious duty of environmental protection agencies. PMID- 29448200 TI - Influence of ore processing activity on Hg, As and Sb contamination and fractionation in soils in a former mining site of Monte Amiata ore district (Italy). AB - A geochemical study was carried out at the former Abbadia San Salvatore (ASS) mining site of the Monte Amiata ore district (Italy). Hg, As and Sb total contents and fractionation using a sequential extraction procedure were determined in soil and mining waste samples. Ore processing activities provided a different contribution to Hg contamination and concentration in soil fractions, influencing its behaviour as volatility and availability. Soils of roasting zone showed the highest Hg contamination levels mainly due to the deposition of Hg released as Hg0 by furnaces during cinnabar roasting. High Hg contents were also measured in waste from the lower part of mining dump due to the presence of cinnabar. The fractionation pattern suggested that Hg was largely as volatile species in both uncontaminated and contaminated soils and mining waste, and concentrations of these Hg species increased as contamination increased. These findings were in agreement with the fact that the ASS mining site is characterized by high Hg concentrations in the air and the presence of Hg0 liquid droplets in soil. Volatile Hg species were also prevalent in uncontaminated soils likely because the Monte Amiata region is an area characterized by anomalous fluxes of gaseous Hg from natural and anthropogenic inputs. At the ASS mining site soils were also contaminated by Sb, while As contents were comparable with its local background in soil. In all soil and waste samples Sb and As were preferentially in residual fraction. PMID- 29448201 TI - Trace element dynamics of biosolids-derived microbeads. AB - This study focused on quantifying and characterising microbeads in biosolids (i.e., treated sewage sludge), and in examining interactions of microbeads with trace elements when biosolids are added to soil. Under laboratory conditions, batch experiments were conducted to investigate the adsorption of Cu onto pure and surface modified microbeads suspended in soil. The ecotoxicity of microbead metal complexes to soil microbial activities was also investigated by monitoring basal respiration and dehydrogenase activity. Concentrations of the microbeads were 352, 146, 324, and 174 particles kg-1 biosolids for <=50, 50-100, 100-250, 250-1000 MUm size fractions, respectively. The Scanning Electron Microscope (SEM) images illustrated wrinkled and fractured surfaces due to degradation. The adsorption of dissolved organic matter onto microbeads was confirmed through FT IR microscopy, while using Inductively Coupled Plasma Mass Spectrometer (ICP-MS) the presence of trace metals including Cd (2.34 ng g-1), Cu (180.64 ng g-1), Ni (12.69 ng g-1), Pb (1.17 ng g-1), Sb (14.43 ng g-1), and Zn (178.03 ng g-1) was revealed. Surface modified microbeads were capable of adsorbing Cu compared to the pure microbeads, which may be attributed to the complexation of Cu with dissolved organic matter associated with the microbeads in the matrix. It was further revealed that the biosolids derived microbead-metal complexes decreased soil respiration (up to ~ 26%) and dehydrogenase activity (up to ~ 39%). Hence, microbeads reaching biosolids during wastewater treatment are likely to serve as a vector for trace element contamination, transportation, and toxicity when biosolids are applied to soil. PMID- 29448202 TI - The Correlation Between Serum Chemokines and Clinical Outcome in Patients with Advanced Biliary Tract Cancer. AB - BACKGROUND: Biliary tract cancers (BTCs) are known to have a dismal prognosis. A number of chemokines play important roles in the progress of BTCs. However, the serum levels of chemokines in BTCs have not yet been explored. METHODS: The sera of healthy donors (n = 8) and patients with BTCs who were enrolled in second line sunitinib trials (n = 27) were collected. The concentrations of three kinds of chemokines (CXCL5, CXCL8 and CXCL12) were measured using ELISA assay. The median concentrations of chemokines were compared between healthy donors and BTC patients and the role of chemokines as a prognostic biomarker was examined. RESULTS: BTC patients generally had higher serum levels of CXCL5 and CXCL12 compared to healthy donors. Patients with cholangiocarcinoma showed significantly higher levels of serum CXCL12 than patients with gallbladder cancer. In survival analysis, only CXCL12 level showed a prognostic impact on overall survival (median OS: 6.9 vs. 0.9 months in low CXCL12 vs. high CXCL12, respectively; P = .008). High CXCL5 levels were also correlated with poor survival without statistical insignificance (median OS: 6.2 vs. 2.0 months in low CXCL5 vs. high CXCL5, respectively; P = .070). CONCLUSIONS: There was a significant difference in OS according to the level of CXCL12, suggesting that serum CXCL12 levels may be a useful surrogate marker for clinical outcome in advanced BTCs. PMID- 29448203 TI - Preoperative Anti-Class III beta-Tubulin Antibodies As Relevant Clinical Biomarkers in Ovarian Cancer. AB - Class III beta-tubulin (TUBB3) overexpression in ovarian cancer (OC) associates with poor prognosis. We investigated whether TUBB3 overexpression elicited anti TUBB3 antibody production in OC patients and whether these antibodies may have diagnostic and prognostic impact. The presence of serum anti-TUBB3 antibodies was investigated in 49 untreated OC patients and 44 healthy individuals by an in house developed ELISA that used recombinant TUBB3 as the antigen. Receiver operating characteristic (ROC) curves were generated to assess the diagnostic accuracy of the assay. Anti-TUBB3 antibodies discriminated OC patients and healthy individuals with excellent sensitivity and specificity (91.8% and 90.9%, respectively). In multivariate analysis, anti-TUBB3 antibody level emerged as an independent prognostic factor for progression free and overall survival. The ELISA was then optimized using a biotin-labeled TUBB3 C-terminal peptide424-450 instead of recombinant TUBB3 as the antigen and streptavidin-coated plates. The diagnostic role of the anti-TUBB3 antibodies was studied in an independent series of 99 OC patients and 80 gynecological benign disease patients. ROC-curve analysis showed a valuable diagnostic potential for serum anti-TUBB3 antibodies to identify OC patients with higher sensitivity and specificity (95.3% and 97.6%, respectively). Overall, our results provide evidence that preoperative anti-TUBB3 antibody level is a promising diagnostic and prognostic biomarker for the management of OC patients. PMID- 29448204 TI - Experimental and computational assessment of mycosynthesized CdO nanoparticles towards biomedical applications. AB - The present study reports the biogenic synthesis of Cadmium Oxide Nanoparticles (CdO NPs) using plant pathogenic fungus Nigrospora oryzae culture filtrate. Further, the effect of the NPs on the cancer cell line (HeLa) is explored. The sample was characterized using Thermogravimetric/Differential Thermal (TG/DTA), Powder X-ray Diffraction (XRD), X-ray Photoelectron spectroscopy (XPS), UV Visible Diffuse Reflectance Spectroscopy (UV-DRS), Field Emission Transmission Electron Microscopy (FE-SEM) with Energy Dispersive X-ray Spectroscopy (EDX), High Resolution Transmission Electron Microscopy (HR-TEM) and Selected Area Electron Diffraction (SAED) analysis. Antibacterial activity was evaluated against both Gram positive and Gram negative bacterial strains and it showed maximum activity against Proteus vulgaris. The larvicidal activity was performed to evaluate the maximum ability of synthesized CdO NPs against Anopheles stephensi. Subsequently, MTT assay also depicted the dose-dependent anticancer activity of CdO NPs against cancer cell line (HeLa). Additionally, the inhibitory effect of CdO NPs was analyzed through extensive docking with cancerous protein agent. Results enlighten that Transketolase protein exhibited high docking score of -4.8 k/mol with H-bond interactions found with Lys75 and Asn185 amino acid residues. DFT study was performed on CdO to understand the charge transfer reaction for the inhibitory mechanism. Convincingly, this study explores the understanding of CdO NPs against HeLa cells. PMID- 29448205 TI - 6,7-dimethoxy-1,2,3,4-tetrahydro-isoquinoline-3-carboxylic acid attenuates colon carcinogenesis via blockade of IL-6 mediated signals. AB - In this study, we investigated the in vivo antiproliferative activity of 6,7 dimethoxy-1,2,3,4-tetrahydro-isoquinoline-3-carboxylic acid (M1) in dimethylhydrazine (DMH) induced colorectal carcinoma (CRC) using albino Wistar rats. M1 was administered to DMH induced CRC rats at 10 and 25 mg/kg doses for 15 days. Various physiological, oxidative parameters, histopathology, ELISA, gene and protein expression studies were conducted to evaluate the anti-CRC potential of M1. The histopathology and biochemical tests indicated the protective action of M1 in DMH-induced colon cancer. ELISA confirms that M1 reduced the increased concentration of IL-6 more prominently than those of IL-2 and COX-2. Gene expression analysis revealed that M1 attenuated the increased mRNA over expression of IL-6, JAK2 and STAT3. The result obtained from quantitative western blot analysis demonstrated that the CRC condition was produced by the IL-6 induced activation/phosphorylation of JAK2 and STAT3 and further down-regulated with M1 treatment. This evidence was supported well with the application of data based mathematical modeling. Applying the fitted model, we predicted the quantitative behavior of STAT3 populations not accessible to experimental measurement. Later, 1H NMR based serum metabolic profiling was carried out using rat sera to investigate the impact of M1 on CRC-induced metabolic alterations. M1 showed its ability to restore the perturbed metabolites in CRC condition. Altogether, our study provided the first time evidence that M1 exhibits anti-CRC potential through the blockade of IL-6/JAK2/STAT3 oncogenic signaling. PMID- 29448206 TI - Regulation of JAK2/STAT3 and NF-kappaB signal transduction pathways; Veronica polita alleviates dextran sulfate sodium-induced murine colitis. AB - Ulcerative colitis (UC) is a major inflammatory bowel disease (IBD) has become a worldwide emergent disease. Veronica polita (VP) is a medicinal herb that has strong antioxidant and anti-inflammatory properties. In the present study, we studied the protective effect of VP on dextran sulfate sodium (DSS)-induced experimental colitis in mice. Phytochemical screening of VP extract demonstrated the presence of high total phenolic and flavonoid contents. Compared with the DSS group, VP significantly reduced clinical symptoms with less weight loss, bloody stool, shortening of the colon, and the severity of colitis was considerably inhibited as evidenced by the reduced disease activity index (DAI) and degree of histological damage in the colon and spleen. Also, treatment with VP considerably decreased the nitric oxide (NO) and malondialdehyde (MDA) level. VP remarkably downregulated the expression of tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta), interleukin-6 (IL-6), inducible nitric oxide synthetase (iNOS) and cyclooxygenase-2 (COX-2) in the colon tissue. Likewise, activation of the signal transducer and activator of transcription 3 (STAT3) and nuclear factor-kappa B (NF-kappaB) was effectively blocked by VP. Taken together, these results demonstrate that VP has an ameliorative effect on colonic inflammation mediated by modulation of oxidative stress and inflammatory mediators by suppressing the JAK2/STAT3 and NF-kappaB signaling pathways. PMID- 29448207 TI - Ferulic acid protects lipopolysaccharide-induced acute kidney injury by suppressing inflammatory events and upregulating antioxidant defenses in Balb/c mice. AB - Sepsis-induced acute kidney injury (AKI) is responsible for 70-80% mortality in intensive care patients due to elevated levels of endotoxin, Lipopolysaccharide (LPS) caused by gram-negative infections. Ferulic acid (FA), a phenolic phytochemical is known for its renal protection on various induced models of nephrotoxicity. However, the curative effect of FA in LPS-induced AKI is not well studied. This study aimed to investigate the effect of FA on LPS-induced AKI in mice model and to understand the protective mechanisms involved, to provide evidence for FA in the treatment of AKI. Balb/c mice were treated with FA at 50 mg/kg and 100 mg/kg dosages after LPS stimulation (10 mg/kg). At the end of the intervention, we determined the concentrations of serum creatinine and blood urea nitrogen, inflammatory cytokines and histopathological changes in animals. Also, the relative protein expression level of TLR4 mediated NF-kappaB signaling pathway were studied in kidney tissues. FA treated animals showed upregulation of antioxidant defenses and suppression of inflammatory events by inhibiting TLR-4 mediated NFkappaB activation. However, LPS alone administered group, resulted in rapid renal damage with increased levels of blood urea nitrogen and modest increase in creatinine; decreased antioxidant defenses and release of inflammatory cytokines. The histopathological analysis also revealed the protective action of the FA against sepsis induced fibrosis and renal damage. Our findings demonstrated that FA exhibits marked protective effects on LPS-induced AKI in mice suggesting its chemopotential role for treating AKI in humans. PMID- 29448208 TI - Microwave hydrothermal-assisted preparation of novel spinel-NiFe2O4/natural mineral composites as microwave catalysts for degradation of aquatic organic pollutants. AB - In this study, novel spinel-NiFe2O4/natural mineral (sepiolite, diatomite and kaolinite) composites were developed using microwave (MW) hydrothermal method, and applied in MW-induced catalytic degradation (NiFe2O4/natural mineral/MW) of organic pollutants such as sodium dodecyl benzene sulfonate (SDBS), azo fuchsine (AF), methyl parathion (MP), and crystal violet (CVL) in solution. Catalytic activities of three NiFe2O4/natural mineral composites were compared. The effects of material synthesis process parameters such as molar ratios of NiFe2O4 and natural mineral, and pH of precursor solutions for synthesizing catalysts, and degradation parameters such as MW irradiation time and catalyst reuse cycles were also investigated. The principle on NiFe2O4/natural mineral/MW degradation was provided. The results reveal that organic pollutants in wastewater can be removed completely using NiFe2O4/natural mineral/MW within minutes. NiFe2O4/sepiolite shows higher catalytic activity than the others. The calculated degradation rate constants are 1.865, 0.672, 0.472, and 0.329 min-1 for SDBS, AF, MP, and CVL, respectively, using NiFe2O4/sepiolite/MW system. The performance of NiFe2O4/natural mineral can be maintained for three reuse cycles. Active species OH, O2-, and h+ play main roles in NiFe2O4/sepiolite/MW degradation. Hence, NiFe2O4/sepiolite/MW technology with rapid and cost-effective degradation, magnetic separation, and no secondary pollution, demonstrates to be promising in treating organic contaminants in wastewater. PMID- 29448209 TI - Metagenomic analysis revealed the prevalence of antibiotic resistance genes in the gut and living environment of freshwater shrimp. AB - Antibiotic resistance disseminating from animals and their environments is a public issue that poses significant threats to human health. In the present study, the diversity and abundance of antibiotic resistance genes (ARGs) in 15 samples from the guts and related aquaculture environments (water and sediment) of shrimp were investigated. In total, 60 ARGs, 102 ARGs and 67 ARGs primarily belonging to 13, 15 and 15 different types were detected in the shrimp gut, pond water and sediment samples, respectively. Efflux pump and target modification were the predominant resistance mechanisms in all samples. It was found that Aeromonas, Yersinia and Clostridium XlVb were significantly correlated with the distribution of the ARGs. Besides, the relative abundance of ARGs was positively correlated with the levels of mobile genetic elements (MGEs). Moreover, variation partitioning analysis showed that MGEs, contributing to 74.46% of the resistome variation, played an important role in the affecting of the antibiotic resistome than the bacterial communities and their joint effects. Collectively, this study provides comprehensive information to better understand the ARG dissemination in aquaculture environments and to improve the ecological management of aquatic ecosystems. PMID- 29448210 TI - Iodate and nitrate transformation by Agrobacterium/Rhizobium related strain DVZ35 isolated from contaminated Hanford groundwater. AB - Nitrate and radioiodine (129I) contamination is widespread in groundwater underneath the Central Plateau of the Hanford Site. 129I, a byproduct of nuclear fission, is of concern due to a 15.7 million year half-life, and toxicity. The Hanford 200 West Area contains plumes covering 4.3 km2 with average 129I concentrations of 3.5 pCi/L. Iodate accounts for 70.6% of the iodine present and organo-iodine and iodide make up 25.8% and 3.6%, respectively. Nitrate plumes encompassing the 129I plumes have a surface area of 16 km2 averaging 130 mg/L. A nitrate and iodate reducing bacterium closely related to Agrobacterium, strain DVZ35, was isolated from sediment incubated in a 129I plume. Iodate removal efficiency was 36.3% in transition cultures, and 47.8% in anaerobic cultures. Nitrate (10 mM) was also reduced in the microcosm. When nitrate was spiked into the microcosms, iodate removal efficiency was 84.0% and 69.2% in transition and anaerobic cultures, respectively. Iodate reduction was lacking when nitrate was absent from the growth medium. These data indicate there is simultaneous reduction of nitrate and iodate by DVZ35, and iodate is reduced to iodide. Results provide the scientific basis for combined nitrogen and iodine cycling throughout the Hanford Site. PMID- 29448211 TI - An integrated bi-level optimization model for air quality management of Beijing's energy system under uncertainty. AB - In this study, an interval chance-constrained bi-level programming (ICBP) method is developed for air quality management of municipal energy system under uncertainty. ICBP can deal with uncertainties presented as interval values and probability distributions as well as examine the risk of violating constraints. Besides, a leader-follower decision strategy is incorporated into the optimization process where two decision makers with different goals and preferences are involved. To solve the proposed model, a bi-level interactive algorithm based on satisfactory degree is introduced into the decision-making processes. Then, an ICBP based energy and environmental systems (ICBP-EES) model is formulated for Beijing, in which air quality index (AQI) is used for evaluating the integrated air quality of multiple pollutants. Result analysis can help different stakeholders adjust their tolerances to achieve the overall satisfaction of EES planning for the study city. Results reveal that natural gas is the main source for electricity-generation and heating that could lead to a potentially increment of imported energy for Beijing in future. Results also disclose that PM10 is the major contributor to AQI. These findings can help decision makers to identify desired alternatives for EES planning and provide useful information for regional air quality management under uncertainty.

AB - Sawdust was expected to remove impurities in waste lubricant, and was modified with sodium hydroxide and triethanolamine, which can ameliorate its surface properties and improve its adsorption capacity. The increase of hydroxyl groups, the decrease of carbonyl groups and grafting new azyl after modification were beneficial for the adsorption of impurities. The surface area of modified sawdust is 0.969 m2 g-1, which is nearly 1.39 times as much as raw sawdust. The point of zero charge for modified sawdust decreased from 6.75 to 5.68 while the crystallinity of modified sawdust increased from 40.35 to 56.16. This research discovered that compared with raw sawdust and filter paper, modified sawdust possessed superior adsorption performances. The removal percentages for Si, Al, Fe, Cu was enhanced from 2.54%, 20.34%, 16.55%, 0.26% to 15.37%, 21.99%, 45.37%, 4.88%, respectively, while that for oxidation, aromatics, sulphation, soot and water was improved by 4.33, 4.69, 0.76, 1.20, 1.28 times at 80 degrees C with 1000 rpm for 12 h. The research has also explored the optimum adsorption conditions (adsorption temperature, adsorption time and rotation rate). The modified sawdust showed a stable adsorption capacity for impurities under different adsorption conditions. PMID- 29448213 TI - Preparation of dumbbell manganese dioxide/gelatin composites and their application in the removal of lead and cadmium ions. AB - The nano-sized sorbents restrict their practical application in flow-through system due to excessive pressure. In this study, dumbbell MnO2/gelatin composites were synthesized based on the protein-assisted synthesis technology. Then they were immobilized on the amino-modified polymethyl methacrylate (PMMA) plate. SEM, TEM, XRD, XPS and FT-IR were employed to study the surface properties and the adsorption mechanism of MnO2/gelatin composites. Adsorption experiments for Pb(II) and Cd(II) ions were performed to study the adsorption isotherms, kinetics, and thermodynamics as well as the influencing factors. The maximum adsorption capacities of Pb(II) and Cd(II) ions were 318.7 mg g-1 and 105.1 mg g 1 respectively. The adsorption process met the pseudo-second-order kinetic model. Subsequently, MnO2/gelatin composites modified plates were used to remove the heavy metal ions in surface water and wastewater samples. The removal efficiencies of Pb(II) ion was changed from 83% (wastewater) to 100% (surface water), when the initial concentration was 10 mg L-1. This device exhibited great application prospect in the removal of heavy metals taking advantage of its high removal efficiency, excellent stability and reusability and ease of operation. PMID- 29448214 TI - Nanoscale zero-valent iron-assisted soil washing for the removal of potentially toxic elements. AB - The present study focuses on soil washing enhancement via soil pretreatment with nanoscale zero-valent iron (nZVI) for the remediation of potentially toxic elements. To this end, soil polluted with As, Cu, Hg, Pb and Sb was partitioned into various grain sizes (500-2000, 125-500 and <125 MUm). The fractions were pretreated with nZVI and subsequently subjected, according to grain size, to Wet High Intensity Magnetic Separation (WHIMS) or hydrocycloning. The results were compared with those obtained in the absence of nanoparticles. An exhaustive characterization of the magnetic signal of the nanoparticles was done. This provided valuable information regarding potentially toxic elements (PTEs) fate, and allowed a metallurgical accounting correction considering the dilution effects caused by nanoparticle addition. As a result, remarkable recovery yields were obtained for Cu, Pb and Sb, which concentrated with the nZVI in the magnetically separated fraction (WHIMS tests) and underflow (hydrocyclone tests). In contrast, Hg, concentrated in the non-magnetic fraction and overflow respectively, while the behavior of As was unaltered by the nZVI pretreatment. All things considered, the addition of nZVI enhanced the efficiency of soil washing, particularly for larger fractions (125-2000 MUm). The proposed methodology lays the foundations for nanoparticle utilization in soil washing operations. PMID- 29448215 TI - Synthesis of dual temperature - and pH-responsive yolk-shell nanoparticles by conventional etching and new deswelling approaches: DOX release behavior. AB - Dual stimuli-responsive yolk-shell nanoparticles with cross-linked poly(acrylic acid) (PAA) pH-responsive core and cross-linked poly(2-hydroxyethyl methacrylate) (PHEMA) temperature-responsive shell were synthesized via two different methods In the first method, silica encapsulated PAA (PAA@SiO2) was used as seed in distillation precipitation polymerization (DPP) of HEMA to yield PAA@SiO2@PHEMA from which silica layer was etched by HF solution to produce yolk-shell PAA@air@PHEMA nanoparticles. In the second method, swollen PAA nanoparticles at pH = 10 were used as seeds in emulsion polymerization of HEMA to yield core-shell PAA@PHEMA nanoparticles. After dispersion of PAA@PHEMA nanoparticles in acidic medium at pH = 2, yolk-shell nanoparticles were formed through deswelling of pH responsive cores due to protonation of carboxyl groups. Synthesized nanoparticles were characterized using FT-IR, FE-SEM and TEM methods to observe yolk-shell nanostructure for both synthesis routes. Stimuli-responsive behavior of the nanoparticles was investigated by UV-vis spectrometer where similar behaviors were obtained for template-assisted and template-free synthesized yolk-shell nanoparticles. Finally, both yolk-shell nanoparticles were examined as potential carriers for controlled release of doxorubicin hydrochloride (DOX) anti-cancer drug. PMID- 29448216 TI - Development of an indolicidin-derived peptide by reducing membrane perturbation to decrease cytotoxicity and maintain gene delivery ability. AB - Indolicidin (IL) is a cationic antimicrobial peptide and our previous study has demonstrated its potential as a cell penetrating peptide (CPP) to promote gene delivery. However, the cytotoxicity of IL arisen from its membrane perturbation capacity may restrict its clinical application. To promote gene delivery safety and efficiency, an almost mirror-symmetric IL derivative, SAP10 (RRWKFFPWRR CONH2), was designed in this study. All-atom molecular dynamics (MD) simulations were performed to understand the association between SAP10 and model lipid bilayers. By comparison with IL, SAP10 with high positively charged density resisted its deep insertion into lipid bilayers, which thus reduced its perturbation to lipid bilayers and improved biocompatibility. Consequently, we further mixed SAP10, polyethylenimine (PEI) and DNA to form the ternary nanocomplexes for gene delivery investigation. Both IL and SAP10 weakened the interaction between to DNA and PEI, which may be beneficial to promote the dissociation of internalized DNA from the carrier molecules. In vitro experiments demonstrated that the SAP10-associated ternary nanocomplexes highly promoted the transfection efficiency to various cells with low cytotoxicity. The effect of the SAP10 on promoting gene delivery was mainly contributed by the adsorbed peptides on the nanoparticles rather than the free ones. In particular, the dose of SAP10 could be increased to broaden the administration window, which ensured its safety on transfection. Therefore, our results suggested the argument that the designed SAP10 is a safe and an efficient peptide to promote PEI-mediated gene delivery. PMID- 29448217 TI - A simple approach for fabrication of optical affinity-based bioanalytical microsystem on polymeric PEN foils. AB - Herein, we report a novel concept of low-cost flexible platform for fluorescence based biosensor. The surface of polyethylene naphthalate (PEN) foil was exposed to KrF excimer laser through a photolitographic contact mask. Laser initiated surface modification resulted in micro-patterned areas with surface functional groups available for localized covalent immobilization of biotin. High affinity binding protein (albumin-binding domain (ABD) of protein G, Streptococcus G148) recognizing human serum albumin (HSA), genetically fused with streptavidin (SA ABDwt), was immobilized on the micro-patterned surface through biotin streptavidin coupling. Fluorescently labelled HSA analyte was detected in several blocking environments, in 1% bovine serum albumin (BSA) and 6% fetal serum albumin (FBS), respectively. We conclude that the presented novel concept enabled us to micropattern functional biosensing layers on the surface of PEN foil in a fast and easy way. It brings all necessary aspects for continuous roll-to-roll fabrication of low-cost optical bioanalytical devices. PMID- 29448218 TI - Polymer adhesion predictions for oral dosage forms to enhance drug administration safety. Part 1: In vitro approach using particle interaction methods. AB - Solid oral dosage forms (SODF) are drug vehicles commonly prescribed by physicists in primary and secondary cares, as they are the most convenient for the patient and facilitate therapy management. Concerns regarding unintended adhesion of SODF during oro-esophageal transit remain, especially in multimorbid patients, bedridden patients and patients suffering from dysphagia. Hence, this factor should be considered during the development of SODF, and more attention should be given on the design of appropriate surface conditions considering patients with swallowing problems. The aim of this work was to estimate the low mucoadhesion strength of different pharmaceutical polymers frequently used in coating technologies, since this property is thought to have impact on the mucoadhesive profile of SODF during oro-esophageal transit. In an approach using in vitro methods based on particle interactions, polyethylene glycol grades (PEG) showed the lowest interaction forces suggesting a more favorable in vivo performance than hydroxypropyl methylcellulose (HPMC), which was found to have the highest particle interaction. Preference should be given to coating formulations with lower concentrations of polymer and grades with low molecular weight. In addition, rheological measurements should be adopted when targeting poor mucoadhesive polymers. PMID- 29448219 TI - Gait & Posture Special Issue: Gait adaptations in response to obstacle type in fallers with Parkinson's disease. AB - BACKGROUND: Gait impairment places older adults and people with Parkinson's disease (PD) at an increased risk of falls when walking over obstacles. Increasing the height of obstacles results in greater challenge to balance however little is known about the demands encountered when negotiating obstacles of greater depth which may be greater for PD who often walk with a short, shuffling gait. RESEARCH QUESTION: To describe gait adaptation in older adults and people with PD when walking over long and tall obstacles. METHODS: 20 people with PD and 13 older adults with a history of falls walked across an instrumented walkway under four conditions: level walking, and over a small, long and tall obstacle. Differences due to group, step and obstacle type were evaluated using General Linear Models. RESULTS: An increased step duration, longer single limb support and a wider step (p < .033) were observed when crossing the tall obstacle for both older adults and PD. The PD group completed the crossing steps more slowly than controls, with a shorter step and longer single limb support (p < .043). Obstacle type did not significantly influence step length. SIGNIFICANCE: The greatest temporal-spatial adaptations were elicited when participants negotiated the tall obstacle. Electing a wider step when crossing the tall obstacle was a strategy common to both faller groups (older adults and PD). The tall obstacle presented added challenge for PD who spent longer in single limb support during the crossing steps compared to controls. The long obstacle did not cause a disproportionate change in step length in people with PD, and we suggest that the obstacle may have acted as a visual cue in this group. PMID- 29448220 TI - Trunk postural balance and low back pain: Reliability and relationship with clinical changes following a lumbar stabilization exercise program. AB - Lumbar stabilization programs reduce pain and disability, but the mechanisms of action underlying this treatment are unknown. Trunk postural control during unstable sitting represents a surrogate measure of motor control mechanisms involved to maintain the dynamic stability of the spine. This exploratory study aimed to determine the reliability of trunk postural control measures over an 8 week interval, their sensitivity to low back pain status and treatment and their relationship with clinical outcomes. Trunk postural control measures were determined in patients with low back pain before and after an 8-week lumbar stabilization exercise program. Healthy controls were assessed over the same interval, but without any treatment, to determine the reliability of the measures and act as a control group at baseline. The kinematics of a wobble chair during unstable sitting was summarized using different linear and nonlinear measures quantifying the quantity and quality of movement, respectively. The reliability of the measures was moderate to excellent. The results showed significant reduction in pain and disability following the intervention. While no impairment at baseline scores was found, some linear and nonlinear measures changed over the intervention period among the patient group. However, for nonlinear measures only, significant correlations were detected with the change scores of pain and disability. The change of measures over the intervention period was likely due to learning rather than the intervention as similar alteration was detected in the healthy subjects. The results suggest that only the quality (not the quantity) of movement may have relationship with pain and disability. PMID- 29448221 TI - Trip-specific training enhances recovery after large postural disturbances for which there is NO expectation. AB - PURPOSE: Informed consent usually provides foreknowledge of experimental methods that can potentially increase expectation of stimuli and, therefore, influence the response. We determined the effects of increased expectation and trip specific training on the recovery response following a treadmill-delivered, trip specific disturbance. To deliver unexpected disturbances, subjects were deceived during the informed consent process. The primary hypothesis was that the recovery response following an expected postural disturbance would be characterized by trunk kinematics that have been shown to decrease the likelihood of a fall, compared to following an unexpected postural disturbance. We further hypothesized that following an unexpected postural disturbance, the recovery response of the subjects who had completed a trip-specific training protocol would be more biomechanically favorable to recovery compared to those of subjects who had not received the training. METHODS: Young adults were randomized into Untrained or Trained groups. During the informed consent process, the purpose of the study was explained to subjects in both groups as being to determine the effect of trip specific training on postural sway while performing an attention-demanding task. Untrained subjects completed two trials during which they minimized their postural sway. During the second trial, an unexpected disturbance was delivered while they performed the attention-demanding task. Trained subjects performed a pre-training postural sway trial, followed by the delivery of a series of expected, training disturbances. Finally, an unexpected disturbance was delivered while they minimized postural sway and performed the attention-demanding task. RESULTS: Expectation significantly improved trunk kinematics (p < .05). In addition, participation in the trip-specific training protocol following the unexpected disturbance the trunk kinematics of the Trained subjects were more biomechanically favorable to recovery than those of the Untrained subjects (p < .01). CONCLUSION: Improved trunk kinematics following trip-specific training may be independent of the extent to which the disturbance is expected. PMID- 29448222 TI - A colorimetric broth microdilution method for assessment of Helicobacter pylori sensitivity to antimicrobial agents. AB - Helicobacter pylori is a major infective etiological agent of the upper gastrointestinal tract diseases. The bacterium exhibits resistance to various conventional antibiotics, being usually challenging for eradication. Since there is an urge to consider alternative therapeutic strategies, the aim of the study was to examine selected essential oils of plants belonging to families Cupressaceae (Juniperus communis) and Lamiaceae (Hyssopus officinalis, Salvia officinalis, Melissa officinalis, Lavandula angustifolia, Ocimum basilicum and Thymus serpyllum) against H. pylori, using an improved microdilution broth method. The oils were examined in concentration range from 0.03 to 4 MUL/mL. The method comprises Brain-heart infusion broth supplemented with yeast extract, horse serum and IsoVitaleX. After 3 day incubation, an equal volume of double strengthen Christensen's urea was added into each well and incubated for additional 4 h. In wells with present H. pylori, the medium changed color from yellow to purple, allowing MIC determination even without a microtitre plate reader. The microtitre format method is convenient as it is less expensive, easier to perform and requires less amount of an anti-H. pylori agent. The improved method enhances specificity to H. pylori, as fast urease activity is almost an exclusive property of this bacterium. The application of the second step incubation with Christensen's urea decreases the possibility of false positive/negative results due to contaminant growth or commonly poor H. pylori growth. Among the examined oils, J. communis, H. officinalis and O. basilicum were not active with the highest applied concentrations, while the most active was T. serpyllum, with MIC 2.0-4.0 MUL/mL. This is the first report on essential oils activity of T. serpyllum and H. officinalis against H. pylori. PMID- 29448223 TI - 2D transition metal carbide MXene as a robust biosensing platform for enzyme immobilization and ultrasensitive detection of phenol. AB - MXene-Ti3C2, as a new class of two-dimensional (2D) transition metal carbides (or nitrides), has been synthesized by exfoliating pristine Ti3AlC2 phases with hydrofluoric acid. The SEM and XRD images show that the resultant MXene possesses a graphene-like 2D nanostructure. and the surface of MXene has been partially terminated with -OH, thus providing a favorable microenvironment for enzyme immobilization and retaining their bioactivity and stability. Considering the unique metallic conductivity, biocompatibility and good dispersion in aqueous phase, the as-prepared MXene was explored as a new matrix to immobilize tyrosinase (a model enzyme) for fabricating a mediator-free biosensor for ultrasensitive and rapid detection of phenol. The varying electrochemical measurements were used to investigate the electrochemical performance of MXene based tyrosinase biosensors. The results revealed that the direct electron transfer between tyrosinase and electrode could be easily achieved via a surface controlled electrochemical process. The fabricated MXene-based tyrosinase biosensors exhibited good analytical performance over a wide linear range from 0.05 to 15.5 MUmol L-1, with a low detection limit of 12 nmol L-1 and a sensitivity of 414.4 mA M-1. The proposed biosensing approach also demonstrated good repeatability, reproducibility, long-term stability and high recovery for phenol detection in real water samples. With those excellent performances, MXene with graphene-like structure is proved to be a robust and versatile electrochemical biosensing platform for enzyme-based biosensors and biocatalysis, and has wide potential applications in biomedical detection and environmental analysis. PMID- 29448224 TI - A review on electrochemical detection of serotonin based on surface modified electrodes. AB - Serotonin is one of the important neurotransmitters of our body. It's abnormal concentration is associated with multiple disorders and diseases. Sensitive and precise electrochemical determination of serotonin is not possible with bare working electrodes due to various reasons viz. electro-chemical fouling, presence of other biological molecules having similar oxidation potential, and lower concentration of serotonin in biological samples. Surface modification of working electrode is required for fast, precise, selective, and sensitive detection of serotonin. We have extensively reviewed the research approaches where serotonin has been sensitively detected using surface modified electrodes in the presence of other interfering agents. This review aims at presenting the electrochemical detection of serotonin using various surface modified electrodes such as glassy carbon, graphite, carbon fiber, diamond, screen printed, ITO, and metal electrodes modified with conducting polymers and polyelectrolytes, carbon nanomaterials, metal or metal oxide nanoparticles, biological compounds, and other conducting materials. The analytical figures of merits of various research approaches for detection of serotonin have been compared in the article. The properties of material used for surface modification, chemical interactions at the interfaces, and electrocatalytic effects of modified surfaces on sensing of serotonin have been thoroughly discussed in this review.

AB - Monitoring cancer biomarkers in biological fluids has become a key tool for disease diagnosis, which should be of easy access anywhere in the world. The possibility of reducing basic requirements in the field of electrochemical biosensing may open doors in this direction. This work proposes for this purpose an innovative electrochemical immunosensing system using a photovoltaic cell as an electrical reading box. Immunosensing ensures accuracy, the electrochemical ground of the device ensures sensitivity and detectability, and the photovoltaic cell drives the system towards electrical autonomy. As proof-of-concept, Carcinoembryonic antigen (CEA) was used herein, a cancer biomarker of clinical relevance. In brief, a conductive glass with a fluorine doped tin oxide film was used as conductive support and modified with anti-CEA by means of a bottom-up approach. All stages involved in the biochemical modification of the FTO surface were followed by electrochemical techniques, namely electrochemical impedance spectroscopy and cyclic voltammetry. This electrode acted as counter electrode of a dye-sensitized solar cells, and the electrical output of this cell was monitored for the different concentrations of CEA. Under optimized conditions, the device displayed a linear behaviour against CEA concentration, from 5 pg/mL to 15 ng/mL. The immunosensor was applied to the analysis of CEA in urine from healthy individual and spiked with the antigen. Overall, the presented approach demonstrates that photovoltaic cells may be employed as an electrical reading box of electrochemical biosensors, yielding a new direction towards autonomous electrochemical biosensing. PMID- 29448226 TI - Insights into the interface effect in Pt@BiOI/ZnO ternary hybrid composite for efficient photodegradation of phenol and photogenerated charge transfer properties. AB - In this work, the ternary hybrid photocatalyst composed of ZnO nanorods with BiOI and Pt NPs (denoted as Pt@BiOI/ZnO) was fabricated by a simple three-step method. The as-prepared samples were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV-Vis diffuse reflectance spectrometry (DRS) and X-ray photoelectron spectroscopy (XPS), which proved the strong interaction has occurred among the Pt, BiOI and ZnO. The phenol degradation test showed that the Pt@BiOI/ZnO ternary hybrid composite exhibited the maximum photodegradation efficiency of phenol (99.9%) under UV irradiation within 30 min compared to Pt/BiOI, BiOI/ZnO binary composites as well as Pt/ZnO. Additionally, the transient photovoltage (TPV), steady-state PL spectra and time-resolved PL spectra were used to investigate the possible mechanism for photocatalytic performance. Our results elaborated that the enhanced photocatalyticactivity was mainly attributed to the synergetic effect of Pt/ZnO and BiOI/ZnO interfaces. Conversely, the interfacial interaction of Pt/BiOI is little contribution, indicating that the effective interfaces design is very important for the degradation of phenol in the preparation process of ternary hybrid photocatalyst. These findings will contribute to developing high efficiency photocatalysts for application in environmental remediation. PMID- 29448227 TI - Alignment of nematic liquid crystals decorated with gemini surfactants and interaction of proteins with gemini surfactants at fluid interfaces. AB - A series of cationic gemini surfactants with diverse chemical structures, that is, imidazolium-based gemini surface active ionic liquids (gemini IM-SAILs) with different alkyl chain length or spacer length, viz. 1,s-bis(3-alkylimidazolium-1 yl) ethane bromide ([Cn-s-Cnim]Br2; s = 2, n = 6, 8, 10, 12, 16; n = 12, s = 2, 4, 6, 10), and quaternary ammonium-based gemini surfactants (gemini QASaa) with different symmetries, viz. 1,2-bisalkylquaternary ammonium bromide (m-2-n; m = 12, 14, 16, n = 8, 10, 12, m + n = 24), were synthesized and utilized to decorate aqueous/liquid crystal interfaces (ALI). Initially, the optical response of the LCs changed from bright to dark after incubation with gemini IM-SAILs (except [C6 2-C6im]Br2) or gemini QASaa aqueous solutions, due to the formation of stable surfactant monolayers at the ALI. We verify that gemini IM-SAILs with shorter spacer or longer hydrophobic chains are more conducive to adsorption onto the interface, and gemini IM-SAILs form monolayers more easily than the corresponding monomers or gemini QASaa. Interestingly, a dark-to-bright shift in the optical image of the LCs subsequently occurred after the fluid interface decorated with the gemini surfactants came into contact with Bovine serum albumin (BSA), a negatively charged protein in neutral environments, whereas the optical appearance of LCs did not change upon addition of two other proteins with positive charge (viz. lysozyme and trypsin). Therefore, based on the different action mechanisms, a low-cost, label-free, and convenient LC-based sensing platform using the gemini surfactant-decorated LC interface was constructed for identification of the proteins with opposite charges. PMID- 29448228 TI - Enhanced demulsification from aqueous media by using magnetic chitosan-based flocculant. AB - A series of quaternized chitosan (QC)-grafted magnetic nanoparticles (MNPs) were successfully synthesized for demulsification from aqueous environments. Fe3O4 MNPs were synthesized by using a coprecipitation method, followed by surface coating with silica and aminopropyl to form a surface for further grafting of QC molecular chains. The synthetic magnetic flocculants were characterized by various technologies and their demulsification performances were evaluated in detail as a function of dosage, QC grafting ratio (Gq), pH and magnetic field. Results showed that pH did not significantly affect oil-water separation performance and MNPs with high Gq exhibited enhanced separation efficiency. The separation capacity was estimated to be >105 mg of diesel oil/mg of magnetic flocculant. Recycling experiment indicated the magnetic flocculant could be recycled up to at least 7 cycles at various pH levels. The grafted QC layer endowed the hybrid MNPs with permanent positive surface charges, thus allowing them to flocculate negatively charged oil droplets via electrostatic patching. The magnetic field could not only accelerate the separation of resulting flocs, but also remove the MNPs-coated dispersed oil droplets. In conclusion, QC-grafted MNPs provide a potentially new technique for developing environmentally friendly and highly efficient magnetic flocculant for practical demulsification applications. PMID- 29448229 TI - Sulfuric acid etching for fabrication of porous MnO2 for high-performance supercapacitor. AB - We developed a facile and efficient route to prepare highly porous nanostructure MnO2 by etching of proton-type layered manganese oxide (H-MnO2) with sulfuric acid (H2SO4). Results from TEM images and N2 adsorption showed that H2SO4 etching created porous MnO2 with average pore size of about 4 nm and high specific surface area (315 m2 g-1). With such porous structure, the obtained MnO2 exhibits a high specific capacitance of 253 F g-1 and enhanced rate capability (62.1% capacitance retention from 0.5 to 10 A g-1) when comparing with the H-MnO2 precursor (154 F g-1, 45.5%) and annealed H-MnO2 in the absence of H2SO4 (134 F g 1, 43.3%). The excellent capacitive properties demonstrate that creation of porous structure on H-MnO2 not only provides large ion-accessible surface area for efficient charge storage, but also to some extent promotes the kinetics of electrochemical reactions. PMID- 29448230 TI - Reversible modulation of the redox activity in conducting polymer nanofilms induced by hydrophobic collapse of a surface-grafted polyelectrolyte. AB - We present the covalent modification of a Pani-like conducting polymer (polyaminobenzylamine, PABA) by grafting of a polyelectrolyte brush (poly [2 (methacryloyloxy)-ethyl-trimethylammonium chloride], PMETAC). As PABA has extra pendant amino moieties, the grafting procedure does not affect the backbone nitrogen atoms that are implicated in the electronic structure of the conducting polymers. Moreover, perchlorate anions interact very strongly with the quaternary ammonium pendant groups of PMETAC through ion pairing. Therefore, the grafting does not only keep the electroactivity of PABA in aqueous solutions but it adds the ion-actuation properties of the PMETAC brush to the modified electrode as demonstrated by contact angle measurements and electrochemical methods. In this way, the conjugation of the electron transfer properties of the conducting polymer with the anion responsiveness of the integrated brush renders perchlorate actuation of the electrochemical response. These results constitute a rational integration of nanometer-sized polymer building blocks that yields synergism of functionalities and illustrate the potentialities of nanoarchitectonics for pushing the limits of soft material science into the nanoworld. PMID- 29448231 TI - Capacity building of midwifery faculty to implement a 3-years midwifery diploma curriculum in Bangladesh: A process evaluation of a mentorship programme. AB - When a midwifery diploma-level programme was introduced in 2010 in Bangladesh, only a few nursing faculty staff members had received midwifery diploma-level. The consequences were an inconsistency in interpretation and implementation of the midwifery curriculum in the midwifery programme. To ensure that midwifery faculty staff members were adequately prepared to deliver the national midwifery curriculum, a mentorship programme was developed. The aim of this study was to examine feasibility and adherence to a mentorship programme among 19 midwifery faculty staff members who were lecturing the three years midwifery diploma-level programme at ten institutes/colleges in Bangladesh. The mentorship programme was evaluated using a process evaluation framework: (implementation, context, mechanisms of impact and outcomes). An online and face-to-face blended mentorship programme delivered by Swedish midwifery faculty staff members was found to be feasible, and it motivated the faculty staff members in Bangladesh both to deliver the national midwifery diploma curriculum as well as to carry out supportive supervision for midwifery students in clinical placement. First, the Swedish midwifery faculty staff members visited Bangladesh and provided a two days on-site visit prior to the initiation of the online part of the mentorship programme. The second on-site visit was five-days long and took place at the end of the programme, that being six to eight months from the first visit. Building on the faculty staff members' response to feasibility and adherence to the mentorship programme, the findings indicate opportunities for future scale-up to all institutes/collages providing midwifery education in Bangladesh. It has been proposed that a blended online and face-to-face mentorship programme may be a means to improving national midwifery programmes in countries where midwifery has only recently been introduced. PMID- 29448232 TI - Jump-and-return sandwiches: A new family of binomial-like selective inversion sequences with improved performance. AB - A new family of binomial-like inversion sequences, named jump-and-return sandwiches (JRS), has been developed by inserting a binomial-like sequence into a standard jump-and-return sequence, discovered through use of a stochastic Genetic Algorithm optimisation. Compared to currently used binomial-like inversion sequences (e.g., 3-9-19 and W5), the new sequences afford wider inversion bands and narrower non-inversion bands with an equal number of pulses. As an example, two jump-and-return sandwich 10-pulse sequences achieved 95% inversion at offsets corresponding to 9.4% and 10.3% of the non-inversion band spacing, compared to 14.7% for the binomial-like W5 inversion sequence, i.e., they afforded non inversion bands about two thirds the width of the W5 non-inversion band. PMID- 29448233 TI - Earth's field NMR detection of oil under arctic ice-water suppression. AB - Earth's field NMR has been developed to detect oil trapped under or in Arctic sea ice. A large challenge, addressed here, is the suppression of the water signal that dominates the oil signal. Selective suppression of water is based on relaxation time T1 because of the negligible chemical shifts in the weak earth's magnetic field, making all proton signals overlap spectroscopically. The first approach is inversion-null recovery, modified for use with pre-polarization. The requirements for efficient inversion over a wide range of B1 and subsequent adiabatic reorientation of the magnetization to align with the static field are stressed. The second method acquires FIDs at two durations of pre-polarization and cancels the water component of the signal after the data are acquired. While less elegant, this technique imposes no stringent requirements. Similar water suppression is found in simulations for the two methods. Oil detection in the presence of water is demonstrated experimentally with both techniques. PMID- 29448235 TI - The effects of screen media content on young children's executive functioning. AB - Children's exposure to screen-based media has raised concerns for many reasons. One reason is that viewing particular television content has been shown to negatively affect children's executive functioning. Yet, it is unclear whether interacting with a touchscreen device affects executive functioning in the same way as the television research suggests. In the current study, 96 2- and 3-year old children completed executive functioning measures of working memory and response inhibition and task switching before and after a brief screen intervention consisting of watching an educational television show, playing an educational app, or watching a cartoon. Children's ability to delay gratification was also assessed. Results indicate that the type of screen intervention had a significant effect on executive functioning performance. Children were more likely to delay gratification after playing an educational app than after viewing a cartoon. In particular instances, children's working memory improved after playing the educational app. These findings emphasize that, for young children's executive functioning, interactivity and content may be more important factors to consider than simply "screen time."

AB - Binge drinking of alcohol during adolescence is a serious public health concern with long-term consequences, including decreased hippocampal and prefrontal cortex volume and deficits in memory. We used RNA sequencing to assess the effects of adolescent binge drinking on gene expression in these regions. Male adolescent alcohol-preferring (P) rats were exposed to repeated binge drinking (three 1-h sessions/day during the dark/cycle, 5 days/week for 3 weeks starting at 28 days of age; ethanol intakes of 2.5-3 g/kg/session). Ethanol significantly altered the expression of 416 of 11,727 genes expressed in the ventral hippocampus. Genes and pathways involved in neurogenesis, long-term potentiation, and axonal guidance were decreased, which could relate to the impaired memory function found in subjects with adolescent alcohol binge-like exposure. The decreased expression of myelin and cholesterol genes and apparent decrease in oligodendrocytes in P rats could result in decreased myelination. In the medial prefrontal cortex, 638 of 11,579 genes were altered; genes in cellular stress and inflammatory pathways were increased, as were genes involved in oxidative phosphorylation. Overall, the results of this study suggest that adolescent binge like alcohol drinking may alter the development of the ventral hippocampus and medial prefrontal cortex and produce long-term consequences on learning and memory, and on control of impulsive behaviors.

AB - Using a large sample of college students, objectives were to examine (1) the overlap between poor sleep and suicide risk status, (2) whether poor sleep was associated with suicide behaviors above and beyond depression, (3) whether sleep problems and depression interacted to predict increased suicidal behaviors or risk, and (4) which specific components of sleep were uniquely associated with suicidal behaviors. Participants were 1700 college students (ages 18-29 years; 65% female) from two universities who completed measures assessing sleep, depressive symptoms, and suicidal behaviors (Suicidal Behaviors Questionnaire Revised [SBQ-R], a composite measure including ideation, past attempt, disclosure to others, and future likelihood of suicide that includes a cutoff for determining participants with suicide risk). Approximately one-quarter (24%) of participants were classified with suicide risk. Four-fifths (82.7%) of participants classified with suicide risk also met cutoff criteria for sleep problems; conversely, almost one-third (31.3%) of the participants classified with sleep problems were also classified with suicide risk. Total sleep problems remained significantly associated with suicidal behaviors above and beyond depressive symptoms, though sleep and depression did not interact to predict suicidal behaviors or risk. When considered together and controlling for sex, the odds of being classified with suicide risk were 6.54 times greater for participants with elevated depressive symptoms and 2.70 times greater for participants with sleep problems. Analyses examining specific sleep domains found shorter sleep duration, having bad dreams, feeling too cold while sleeping, and sleep medication use to each be independently associated with suicidal behaviors. Findings add to a growing body of literature linking sleep and suicide in college students. PMID- 29448237 TI - The effect of multimorbidity on the gap between global and age-comparative self rated health scores among the Korean elderly. AB - Most of the behavior change models regard perceived health status as a motivation for healthy behaviors or chronic disease self-management. The aim of this study was to examine the association between the number of chronic diseases and the difference between global and age-comparative self-rated health scores (GSRH and ASRH). We used national representative survey data pertaining to the elderly in 2011 from the Korea Institute for Health and Social Affairs. In total, 10,003 participants (>=60 years old) were selected from those who had completed the survey in 2008. Multinomial logistic regression was used to estimate relative risk ratios (RRR) with 95% confidence intervals. Demographic factors, socioeconomic status, social connection, and healthy life style were adjusted. Individuals with many chronic diseases were more likely to have a positive gap, resulting in a better ASRH score relative to GSRH (p for trend <0.001): 1-2 diseases (RRR = 1.30, 95% CI = 1.07-1.57), 3-4 diseases (RRR = 1.90, 95% CI = 1.55-2.32), and >=5 diseases (RRR = 1.75, 95% CI = 1.39-2.20). In addition, the association between the number of chronic diseases and a positive gap varied by sex and living area. Our results suggest that a positive gap between GSRH and ASRH that indicates an overestimated age-comparative health, was associated with the number of chronic diseases. Female or urban-living people had stronger associations. Further research is needed to understand how the gap between GSRH and ASRH could be an alternative measure of SRH and a predictor of major health outcomes. PMID- 29448239 TI - Bioaccessibility and bioavailability of environmental semi-volatile organic compounds via inhalation: A review of methods and models. AB - Semi-volatile organic compounds (SVOCs) present in indoor environments are known to cause adverse health effects through multiple routes of exposure. To assess the aggregate exposure, the bioaccessibility and bioavailability of SVOCs need to be determined. In this review, we discussed measurements of the bioaccessibility and bioavailability of SVOCs after inhalation. Published literature related to this issue is available for 2,3,7,8-tetrachlorodibenzo-p-dioxin and a few polycyclic aromatic hydrocarbons, such as benzo[a]pyrene and phenanthrene. Then, we reviewed common modeling approaches for the characterization of the gas- and particle-phase partitioning of SVOCs during inhalation. The models are based on mass transfer mechanisms as well as the structure of the respiratory system, using common computational techniques, such as computational fluid dynamics. However, the existing models are restricted to special conditions and cannot predict SVOC bioaccessibility and bioavailability in the whole respiratory system. The present review notes two main challenges for the estimation of SVOC bioaccessibility and bioavailability via inhalation in humans. First, in vitro and in vivo methods need to be developed and validated for a wide range of SVOCs. The in vitro methods should be validated with in vivo tests to evaluate human exposures to SVOCs in airborne particles. Second, modeling approaches for SVOCs need to consider the whole respiratory system. Alterations of the respiratory cycle period and human biological variability may be considered in future studies. PMID- 29448238 TI - Parsing the heterogeneity of depression: An exploratory factor analysis across commonly used depression rating scales. AB - BACKGROUND: Due to the heterogeneity of depressive symptoms-which can include depressed mood, anhedonia, negative cognitive biases, and altered activity levels researchers often use a combination of depression rating scales to assess symptoms. This study sought to identify unidimensional constructs measured across rating scales for depression and to evaluate these constructs across clinical trials of a rapid-acting antidepressant (ketamine). METHODS: Exploratory factor analysis (EFA) was conducted on baseline ratings from the Beck Depression Inventory (BDI), the Hamilton Depression Rating Scale (HAM-D), the Montgomery Asberg Depression Rating Scale (MADRS), and the Snaith-Hamilton Pleasure Rating Scale (SHAPS). Inpatients with major depressive disorder (n = 76) or bipolar depression (n = 43) were participating in clinical ketamine trials. The trajectories of the resulting unidimensional scores were evaluated in 41 subjects with bipolar depression who participated in clinical ketamine trials. RESULTS: The best solution, which exhibited excellent fit to the data, comprised eight factors: Depressed Mood, Tension, Negative Cognition, Impaired Sleep, Suicidal Thoughts, Reduced Appetite, Anhedonia, and Amotivation. Various response patterns were observed across the clinical trial data, both in treatment effect (ketamine versus placebo) and in degree of placebo response, suggesting that use of these unidimensional constructs may reveal patterns not observed with traditional scoring of individual instruments. LIMITATIONS: Limitations include: 1) small sample (and related inability to confirm measurement invariance); 2) absence of an independent sample for confirmation of factor structure; and 3) the treatment resistant nature of the population, which may limit generalizability. CONCLUSIONS: The empirical identification of unidimensional constructs creates more refined scores that may elucidate the connection between specific symptoms and underlying pathophysiology.

AB - 186Re (T1/2 = 89.24 h, [Formula: see text] 346.7 keV, [Formula: see text] ), an intense beta-emitter shows great potential to be used as an active material in therapeutic radiopharmaceuticals due to its suitable physico-chemical properties. 186Re can be produced in several ways, however charged-particle induced reactions show to be promising towards no carrier added production. In this work, production cross-sections of 186Re were evaluated following the light-charged particle induced reactions on tungsten. An effective evaluation technique such as Simultaneous Evaluation on KALMAN code combined with least squares concept was used to obtain the evaluated data together with covariances. Knowledge of the underlying uncertainties in evaluated nuclear data, i.e., covariances are useful to improve the accuracy of nuclear data. PMID- 29448241 TI - Comprehensive analysis of differentially expressed profiles of Alzheimer's disease associated circular RNAs in an Alzheimer's disease mouse model. AB - Circular RNAs (circRNAs), a novel kind of non-coding RNA, have received increasing attention for their involvement in pathogenesis of Alzheimer's disease (AD); however, few studies have reported in the characterization and function of AD associated circRNAs. Here the expression profiles of circRNAs in 5- and 10 month-old SAMP8 mice were identified using circRNA microarray and found that 85 dysregulated circRNAs were observed in 10-month-old SAMP8 versus control mice and 231 circRNAs exhibited differential expression in 10-month-old SAMP8 versus 5 month-old SAMP8. One most significantly dysregulated circRNA, mmu_circRNA_017963, was select for Gene Oncology (GO) and pathway analysis. The results showed that mmu_circRNA_017963 was strongly related with autophagosome assembly, exocytosis, apoptotic process, transport and RNA splicing and highly associated with synaptic vesicle cycle, spliceosome, glycosaminoglycan and SNARE interactions in vesicular transport pathways. Collectively, this study was the first to describe circRNAs expression in different ages of SAMP8 and will contribute to the understanding of the regulatory roles of circRNAs in AD pathogenesis and provide a valuable resource for the diagnosis and therapy of AD. PMID- 29448244 TI - miR-499 Ameliorates Podocyte Injury by Targeting Calcineurin in Minimal Change Disease. AB - BACKGROUND: Podocyte injury is a hallmark of minimal change disease (MCD). Calcineurin inhibitors have been widely used in the current treatment of MCD, and miR-499 may target calcineurin. We aimed to study the function of miR-499 in MCD and test whether miR-499 delivery can improve MCD. METHODS: An MCD mouse model was generated using puromycin aminonucleoside (PAN). MiR-499 was delivered using lentiviruses. Biochemical indicators including serum albumin, triglyceride, cholesterol, and 24-h urine protein were determined. Targets of miR-499 were confirmed using reporter gene activity assays. The ultrastructure of podocytes was analyzed using transmission electron microscopy. RESULTS: MiR-499 significantly improved MCD-related symptoms and signs. Foot-process effacement was caused by PAN and partially reversed by miR-499. We identified that both CnAalpha and CnAbeta were targets of miR-499, and were overexpressed in the presence of PAN. However, miR-499 reduced the expression of CnAalpha and CnAbeta, leading to a decreased activity of calcineurin signaling in mouse podocytes in vitro and in vivo. In addition, miR-499 recovered PAN-induced reduction of cell viability. CONCLUSIONS: MiR-499 ameliorated podocyte injury by targeting CnAalpha and CnAbeta in a PAN-induced MCD mouse model. Delivery of miR-499 can be a novel strategy for MCD treatment. PMID- 29448242 TI - The LncRNA EPEL Promotes Lung Cancer Cell Proliferation Through E2F Target Activation. AB - BACKGROUND/AIMS: Recent studies have revealed that many long non-coding RNAs (lncRNAs) play oncogenic or tumor-suppressive roles in various cancers. Lung cancer is the leading cause of cancer-related death worldwide, and many lung cancer patients frequently relapse after surgery, even those in the early stages. However, the oncogenic or tumor-suppressive roles and clinical implications of lncRNAs in lung cancer have not been fully elucidated. METHODS: The association between an E2F-mediated cell proliferation enhancing lncRNA (EPEL) expression and lung cancer patient survival was accessed using public microarray data with clinical information. Cancer-related phenotypes were analyzed by the siRNA knockdown of EPEL in two lung cancer cell lines. Gene set analysis of gene expression data were performed to identify pathways regulated by EPEL. RNA immunoprecipitation, RT-qPCR, and ChIP assays were performed to explore the functions of selected target genes regulated by EPEL. RESULTS: EPEL, known as LOC90768 and MGC45800, was associated with the relapse and survival of lung cancer patients and promoted lung cancer cell proliferation through the activation of E2F target genes. EPEL knockdown specifically down-regulated the expression of cell cycle-related E2F target genes, including Cyclin B1 (CCNB1), in lung cancer cells but not that of apoptosis- or metabolism-related E2F target genes. EPEL interacted with E2F1 and regulated the expression of the E2F target genes by changing the binding efficiency of E2F1 to the E2F target promoters. Moreover, the expression levels of EPEL and CCNB1 both alone and in combination were robust prognostic markers for lung cancer. CONCLUSIONS: Considering its specific effects on cell cycle-related E2F target genes and its significant association with the prognosis of lung cancer patients, we suggest that the transcriptional regulation of EPEL through E2F target genes is potentially a target for the development of novel therapeutic strategies for lung cancer patients. PMID- 29448243 TI - Impact of Health Authority Control Measures Aimed at Reducing the Illicit Use of Anabolic-Androgenic Steroids. AB - OBJECTIVE: To evaluate two interventions on anabolic-androgenic-steroids (AAS) dispensation in retail pharmacies. MATERIAL AND METHODS: The study was conducted in a north-western region of Spain. Data were the AAS supplied by wholesale drug distributors to retail pharmacies over a period of 102 months. It is designed as an ecological time-series study; the dependent variables were daily defined doses per 1,000 inhabitants per day of each drug. The two interventions evaluated were: (1) an inspection program intended for those retail pharmacies where there was an irregular dispensation and (2) a regulation put forth forcing these pharmacies to carry out additional registers. The medications studied were stanozolol, nandrolone, methenolone, testosterone and mesterolone. RESULTS: The pre intervention use of AAS displayed a rising trend. There was an immediate reduction of 30.56% after the first intervention, and a further reduction of 35.25% after the second. There was a seasonal pattern of use in the pre intervention period, pointing to an increased demand at the end of spring and beginning of summer. The most abused drugs were stanozolol and nandrolone. CONCLUSION: The health actions were very effective, in that they brought about a sharp reduction in the illicit use of AAS. These interventions could be applied to other drugs in which abuse were detected. PMID- 29448245 TI - Does Endothelin-1 Raise or Lower Blood Pressure in Humans? AB - : Subject of Review: Gupta et al. [Cell 2017; 170: 522-533] have shown that a genetic variant associated with the 5 vascular diseases is a distal regulator of endothelin (ET)-1 gene (EDN1) expression. A common single nucleotide polymorphism (SNP) in the third intron of the PHACTR1 gene, rs9349379, is the potential variant responsible for increased risk of coronary artery disease, and lower risk of migraine, carotid dissection, fibromuscular dysplasia, and hypertension. Since ET-1 acts through ET type B receptors (ETBR) on endothelial cells to stimulate the production of nitric oxide and prostacyclin and induce vasodilation, this may contribute to these findings. Second Opinion: However, ET-1 has been demonstrated to play a role in experimental and human hypertension. How can enhanced transcription of EDN1 and translation leading to increased production of ET-1 by endothelial cells play a role in hypertension despite the availability of data that suggest a hypotensive action of ET-1? This could depend on the genetic background of individuals. In some humans, the increased ET-1 vasoconstrictor action on ETAR and ETBR in vascular smooth muscle might predominate over the vasodilator effects exerted via endothelial ETBR, thus resulting in elevated blood pressure. CONCLUSION: Alternatively, hypertension could be attributed to renal actions of ET-1. Either of these pathophysiological actions may explain a hypertensive role of ET-1 despite a lower risk of hypertension associated with the G allele at rs9349379, the common SNP in the PHACTR1 gene that is a distal regulator of EDN1 and leads to an increased expression of ET-1. PMID- 29448246 TI - Effect of Mst1 on Endometriosis Apoptosis and Migration: Role of Drp1-Related Mitochondrial Fission and Parkin-Required Mitophagy. AB - BACKGROUND/AIMS: Mitochondrial homeostasis is implicated in the development and progression of endometriosis through poorly defined mechanisms. Mst1 is the major growth suppressor related to cancer migration, apoptosis and proliferation. However, whether Mst1 is involved in endometriosis apoptosis and migration via regulating the mitochondrial function remains to be elucidated. METHODS: Expression of Mst1 in endometriosis was examined via western blots. Cellular apoptosis was detected via MTT and TUNEL assay. Gain of function assay about Mst1 was conducted via adenovirus over-expression. Mitochondrial functions were evaluated via mitochondrial membrane potential JC-1 staining, ROS flow cytometry analysis, mPTP opening assessment and immunofluorescence of HtrA2/Omi. The mitophagy activity were examined via western blots and immunofluorescence. RESULTS: First, we found that Mst1 was significantly downregulated in the ectopic endometrium of endometriosis compared to the normal endometrium. However, the recovery of Mst1 function was closely associated with the inability of endometrial stromal cells (ESCs) to migrate and survive. A functional study indicated that regaining Mst1 enhanced Drp1 post-transcriptional phosphorylation at Ser616 and repressed Parkin transcription activity via p53, leading to mitochondrial fission activation and mitophagy inhibition. Excessive Drp1-related fission forced the mitochondria to liberate HtrA2/Omi into the cytoplasm. Moreover, Mst1-induced defective mitophagy evoked cellular oxidative stress, energy metabolism and calcium overload. Through excessive mitochondrial fission and aberrant mitophagy, Mst1 launched caspase 9-related mitochondrial apoptosis and abrogated F-actin/lamellipodium-dependent cellular migration. Notably, we also defined NR4A/miR181c as the upstream signal for Mst1 dysfunction in endometriosis. CONCLUSION: Collectively, our results comprehensively described the important role of the NR4A-miR181c-Mst1 pathway in endometriosis, which handled mitochondrial apoptosis and F-actin/ lamellipodium-based migration via the regulation of Drp1-related mitochondrial fission and Parkin-required mitophagy, with a potential application in endometriosis therapy by limiting ESCs migration and promoting apoptosis. PMID- 29448247 TI - Knockdown of MAGEA6 Activates AMP-Activated Protein Kinase (AMPK) Signaling to Inhibit Human Renal Cell Carcinoma Cells. AB - BACKGROUND/AIMS: Melanoma antigen A6 (MAGEA6) is a cancer-specific ubiquitin ligase of AMP-activated protein kinase (AMPK). The current study tested MAGEA6 expression and potential function in renal cell carcinoma (RCC). METHODS: MAGEA6 and AMPK expression in human RCC tissues and RCC cells were tested by Western blotting assay and qRT-PCR assay. shRNA method was applied to knockdown MAGEA6 in human RCC cells. Cell survival and proliferation were tested by MTT assay and BrdU ELISA assay, respectively. Cell apoptosis was tested by the TUNEL assay and single strand DNA ELISA assay. The 786-O xenograft in nude mouse model was established to test RCC cell growth in vivo. RESULTS: MAGEA6 is specifically expressed in RCC tissues as well as in the established (786-O and A498) and primary human RCC cells. MAGEA6 expression is correlated with AMPKalpha1 downregulation in RCC tissues and cells. It is not detected in normal renal tissues nor in the HK-2 renal epithelial cells. MAGEA6 knockdown by targeted shRNA induced AMPK stabilization and activation, which led to mTOR complex 1 (mTORC1) in-activation and RCC cell death/apoptosis. AMPK inhibition, by AMPKalpha1 shRNA or the dominant negative AMPKalpha1 (T172A), almost reversed MAGEA6 knockdown-induced RCC cell apoptosis. Conversely, expression of the constitutive-active AMPKalpha1 (T172D) mimicked the actions by MAGEA6 shRNA. In vivo, MAGEA6 shRNA-bearing 786-O tumors grew significantly slower in nude mice than the control tumors. AMPKalpha1 stabilization and activation as well as mTORC1 in-activation were detected in MAGEA6 shRNA tumor tissues. CONCLUSION: MAGEA6 knockdown inhibits human RCC cells via activating AMPK signaling. PMID- 29448248 TI - LncRNA GAS5 Overexpression Reverses LPS-Induced Inflammatory Injury and Apoptosis Through Up-Regulating KLF2 Expression in ATDC5 Chondrocytes. AB - BACKGROUND/AIMS: Osteoarthritis (OA) is the most frequently occurring joint disease and characterized by degeneration of cartilage. As the unique cell type in cartilage, chondrocytes play a crucial role during OA. Our study explored the influence of long non-coding RNA (lncRNA) growth arrest-specific transcript 5 (GAS5) on lipopolysaccharides (LPS)-induced injury in ATDC5 cells. METHODS: Cell viability, apoptosis and expression of inflammatory cytokines were all assessed to evaluate LPS-induce inflammatory injury. Expression of GAS5 in LPS-induced cells was evaluated by qRT-PCR. After cell transfection, effect of abnormally expressed GAS5 on LPS-induced inflammatory injury was determined. Then, the possible target of GAS5 was screened by bioinformatics and verified by qRT-PCR and luciferase activity assay. Together, whether aberrant expression of target gene affected the modulation of GAS5 in LPS-induced inflammatory injury was also assessed. Finally, the influences of aberrant expressed Kruppel-like factor 2 (KLF2) on nuclear factor kappaB (NF-kappaB) and Notch pathways were detected by Western blot analysis. RESULTS: LPS reduced cell viability and promoted cell apoptosis and secretion of inflammatory cytokines, along with down-regulation of GAS5. LPS-induced injury was alleviated by GAS5 overexpression while was exacerbated by GAS5 silence. KLF2 was predicted and verified as a target of GAS5, and GAS5 functioned through regulating expression of KLF2. Besides, aberrant expression of KLF2 regulated expressions of key kinases involved in the NF-kappaB and Notch pathways. CONCLUSION: GAS5 might ameliorate LPS-induced inflammatory injury in ATDC5 chondrocytes by inhibiting the NF-kappaB and Notch signaling pathways. PMID- 29448249 TI - The Placental Secretome: Identifying Potential Cross-Talk Between Placenta and Islet beta-Cells. AB - BACKGROUND/AIMS: Insulin-secreting islet beta-cells adapt to the insulin resistance associated with pregnancy by increasing functional beta-cell mass, but the placental signals involved in this process are not well defined. In the current study, we analysed expression of G-protein coupled receptor (GPCR) mRNAs in mouse islets and islet GPCR ligand mRNAs in placenta during pregnancy to generate an atlas of potential interactions between the placenta and beta-cells to inform future functional studies of islet adaptive responses to pregnancy. METHODS: Quantative RT-PCR arrays were used to measure mRNA expression levels of: (i) 342 GPCRs in islets from non-pregnant mice, and in islets isolated from mice on gestational days 12 and 18; (ii) 126 islet GPCR ligands in mouse placenta at gestational days 12 and 18. RESULTS: At gestational day 12, a time of rapid expansion of the beta-cell mass, 189 islet GPCR mRNAs were quantifiable, while 79 of the 126 known islet GPCR ligand mRNAs were detectable in placental extracts. Approximately half of the quantifiable placental GPCR ligand genes were of unknown function in beta-cells. The expression of some islet GPCR and placental ligand mRNAs varied during pregnancy, with altered expression of both GPCR and ligand mRNAs by gestational day 18. CONCLUSION: The current study has revealed numerous potential routes for interaction between the placenta and islets, and offers an atlas to inform further functional studies of their roles in adaptive responses to pregnancy, and in the regulation of the beta-cell mass. PMID- 29448250 TI - Overexpression of Lymphocyte Antigen 6 Complex, Locus E in Gastric Cancer Promotes Cancer Cell Growth and Metastasis. AB - BACKGROUND/AIMS: Lymphocyte antigen 6 complex, locus E (LY6E) is a member of the lymphostromal cell membrane Ly6 superfamily protein. The present study investigated the clinical significance and potential biological function of LY6E in gastric cancer (GC). METHODS: LY6E mRNA and protein expressions in human GC tissues and GC cells were tested. Relationship between LY6E expression and the GC patients' clinicopathologic characteristics was analyzed. LY6E was silenced by siRNA in the cultured GC cells. RESULTS: The RNA expression microarray profiling assay results demonstrated that LY6E mRNA was significantly increased in multiple human GC tumor tissues. Immunohistochemistry (IHC) staining analysis revealed that 59 of 75 (78.7%) GC specimens were LY6E positive. LY6E over-expression in human GC was correlated with the histology grade, AJCC stage, N classification, lymphatic invasion, and tumor location. Notably, functional LY6E expression was also detected in AGS and other established GC cell lines. LY6E knockdown by targeted-siRNA inhibited AGS cell survival and proliferation. Meanwhile, the LY6E siRNA induced G1-S cell cycle arrest and apoptosis in AGC cells. Additionally, AGC cell migration was also inhibited by LY6E knockdown. Expressions of tumor suppressing proteins, including PTEN (phosphatase and tensin homolog) and E Cadherin, were increased in LY6E-silenced AGS cells. CONCLUSION: LY6E over expression in GC is potentially required for cancer cell survival, proliferation and migration. PMID- 29448252 TI - Functions and Roles of Long-Non-Coding RNAs in Human Nasopharyngeal Carcinoma. AB - Nasopharyngeal carcinoma (NPC) is one of the most common cancers originating in the nasopharynx and occurring at high frequency in South-eastern Asia and North Africa. Long non-coding RNAs (lncRNAs) are a class of non-protein-coding RNA molecules and key regulators of developmental, physiological, and pathological processes in humans. Emerging studies have shown that lncRNAs play critical roles in tumorgenicity and cancer prognosis. With the development of deep sequencing analyses, an extensive amount of functional lncRNAs have been discovered in nasopharyngeal carcinoma tissues and cell lines. However, the roles and mechanisms of aberrantly expressed lncRNAs in the pathogenesis of NPC are not fully understood. In this review, we briefly illustrate the concept, identification, functional characterization, and summarize recent advancements of biological functions of lncRNAs with heterogeneous mechanistic characterization and their involvement in NPC. Then, we describe individual lncRNAs that have been associated with tumorgenesis, growth, invasion, cancer stem cell differentiation, metastasis, drug resistance and discuss the strategies of their therapeutic manipulation in NPC. We also review the emerging insights into the role of lncRNAs and their potential as biomarkers and therapeutic targets for novel treatment paradigms. Finally, we highlight the up-to-date of clinical information involving lncRNAs and future directions in the linking lncRNAs to potential gene therapies, and how modifications of lncRNAs can be exploited for prevention and treatment of NPC. PMID- 29448251 TI - Expression of Lectin-Like Oxidized Low-Density Lipoprotein Receptor-1 in Human Epicardial and Intramyocardial Coronary Arteries of Male Patients Undergoing Coronary Artery Bypass Grafting. AB - OBJECTIVES: Atherosclerosis is almost absent in intramyocardial coronary arteries, while epicardial coronary arteries may show extensive occlusive disease. Lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) expression has been implicated in atherogenesis. We aimed to investigate differences in arterial wall LOX-1 expression between human epicardial and intramyocardial coronary arteries. METHODS: Epicardial and intramyocardial total artery wall specimens were obtained from 13 male patients (aged 61.9 +/- 10.3 years) undergoing coronary artery bypass graft surgery due to 3-vessel coronary artery disease. LOX-1 expression was examined by reverse transcription-polymerase chain reaction. RESULTS: LOX-1 expression was significantly higher in the arterial wall of epicardial coronary arteries compared to intramyocardial coronary arteries. The LOX-1/GAPDH ratio was 0.48 +/- 0.07 vs. 0.35 +/- 0.03 (p < 0.001). CONCLUSIONS: Our findings may partially explain the atheroprotective effect of the intramyocardial course since arterial wall LOX-1 expression was lower in intramyocardial arteries and higher in epicardial coronary arteries. PMID- 29448253 TI - Lycorine Suppresses Endplate-Chondrocyte Degeneration and Prevents Intervertebral Disc Degeneration by Inhibiting NF-kappaB Signalling Pathway. AB - BACKGROUND/AIMS: Cartilaginous endplate (CEP) degeneration is an important cause for intervertebral disc (IVD) degeneration that leads to low-back pain. The identification of compounds that may prevent CEP degeneration is of interest for the prevention of IVD degeneration. METHODS: Catabolic protease expression in the CEP of disc degeneration patients was first assessed. The toxicity, function and underlying mechanism of lycorine (LY) on CEP-derived chondrocytes degeneration were assessed in vitro by flow cytometry analysis and western blotting. The concentration and function of LY in rat-tail disc-degeneration models were also assessed by HPLC (High Performance Liquid Chromatography) quantification and histological analysis. RESULTS: In CEP cells, Interleukin (IL)-1beta upregulated the expression of matrix metalloproteinase (MMP)-3, MMP-13, a disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS)-4 and ADAMTS-5 that is critical for the degradation of cartilage extracellular matrix. Interestingly, LY suppressed the expression of these enzymes via the inhibition of nuclear factor kappaB (NFkappaB) signalling and thus prevented IL-1beta-induced endplate cell degeneration in vitro. More importantly, LY also reduced the expression of MMP-3, MMP-13, ADAMTS-4 and ADAMTS-5 in CEP and exerted a protective effect on both CEP and nucleus pulposus (NP) degeneration. In addition to its inhibitory effect on matrix-degrading protease expression, LY treatment also reduced positive regulators of proinflammatory cytokines, such as MIF, which can be secreted by CEP cells and subsequently target NP cells. CONCLUSION: LY could serve as a potential drug for treating IVD disease. PMID- 29448254 TI - Microarray Expression Profile of Circular RNAs in Peripheral Blood Mononuclear Cells from Active Tuberculosis Patients. AB - BACKGROUND/AIMS: Dysregulated expression of circular RNAs (circRNAs) was demonstrated to be implicated in many diseases. Here, we aimed to determine circRNA profile in peripheral blood mononuclear cells (PBMCs) from active tuberculosis (TB) patients to identify novel biomarkers for TB. METHODS: Expression profile of circRNAs in PBMCs from 3 active pulmonary TB patients and 3 healthy controls were analyzed by microarray assay. Six circRNAs were selected for validation using real time-quantitative PCR (qRT-PCR) in 40 TB patients and 40 control subjects. Receiver operating characteristic (ROC) curve was constructed to evaluate their values in TB diagnosis. Hsa_circRNA_001937 was chosen for further evaluation in an independent cohort consisting of 115 TB, 40 pneumonia, 40 COPD, 40 lung cancer patients and 90 control subjects. An eight month follow up was performed in 20 newly diagnosed TB patients to investigate the expression change of hsa_circRNA_001937 after chemotherapy. RESULTS: We revealed and confirmed that a number of circRNAs were dysregulated in TB patients. Of the six studied physio circRNAs, the levels of hsa_circRNA_001937, hsa_circRNA_009024 and hsa_ circRNA_005086 were significantly elevated and hsa_circRNA_102101, hsa_circRNA_104964 and hsa_circRNA_104296 were significantly reduced in PBMCs from TB patients as compared to healthy controls. ROC curve analysis suggested that hsa_circRNA_001937 has the largest area under the curve (AUC = 0.873, P<0.001). Hsa_circRNA_001937 was significantly increased in patients with TB compared with patients with pneumonia, COPD and lung cancer. Hsa_ circRNA_001937 was correlated with TB severity (r = 0.4053, P = 0.010) and its expression significantly decreased after treatment. CONCLUSION: This study identified a set of deregulated circRNAs in active TB PBMCs, our data also suggest that hsa_circRNA_001937 can be used as a potential diagnostic biomarker of TB.

AB - The functioning of microglial cells inside the central nervous system depends on their ion channels expression. Microglia are capable of synthesizing different cytokines and chemokines, including CXCL1, and responding to their action via specific receptors. In this study, we explore the effect of intrathecal injection of CXCL1 on potassium currents, expressed in CX3CR1-Green Fluorescent Protein labeled microglia in transgenic mice. The results showed that CXCL1 hyperpolarized the cells by enhancing inward rectifying potassium currents and increasing the membrane area, suggesting an activating effect on microglia.

AB - Systemic lupus erythematosus (SLE) is a major cause of nonbacterial thrombotic endocarditis (NBTE) associated with intracardiac sterile vegetations. It is rare for vegetations to present as an atrial tumor. This report describes a 48-year old female with SLE and antiphospholipid syndrome complicated by recurrent thrombosis on anticoagulation. A large left atrial mass lesion was detected on echocardiography during a work-up for leg burning. Infective endocarditis could not be confirmed, and hence left atrial mass lesion was the most likely diagnosis. The patient was managed surgically and the pathology report revealed fibrin networks in a pattern similar to that of thrombosis, characteristic of NBTE. PMID- 29448258 TI - Altered Long Noncoding RNA and Messenger RNA Expression in Experimental Intracerebral Hemorrhage - a Preliminary Study. AB - BACKGROUND/AIMS: Functional recovery in the chronic phase is a difficult problem in intracerebral hemorrhage (ICH) treatment. Long noncoding RNAs (lncRNAs) are demonstrated to be involved in central nervous system (CNS) disorders. However, the roles of lncRNAs in post-ICH injury and repair are poorly understood, especially those that may be attributed to long-term neurological deficit. The present study depicted the lncRNA and messenger RNA (mRNA) profile by microarray at late stage after an experimental ICH. METHODS: LncRNA and mRNA microarray was used to first identify differentially expressed genes. Gene ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were performed to determine bio-functions and signaling pathways, with which differentially expressed genes are most closely related. Quantitative real-time polymerase chain reaction (PCR) was used to validate the results of microarray. Finally, the lncRNA-mRNA co-expression network was constructed to find the interaction of genes. RESULTS: A total of 625 differentially expressed lncRNAs and 826 expressed mRNAs were identified. Altered genes were enriched in mitochon-drial matrix, G protein coupled receptor signaling pathway, and olfactory transduction, which may be associated with ICH-induced pathophysiologic changes in the long term. A co expression network profile based on 5 validated differentially expressed lncRNAs and 205 interacted mRNAs was composed of 210 nodes and 298 connections. CONCLUSION: Mitochondrial matrix, reduced G-protein coupled receptor activity, and impaired olfactory transduction may be involved in the sequelae following ICH. Further, these dysregulated lncRNAs and mRNAs may be the promising therapeutic targets to overcome obstacles in functional recovery following ICH. PMID- 29448259 TI - Applicability of Computerized Planimetric Method in Estimating Plaque Accumulation and Efficacy of a Cleaning Method for Removable Dental Prostheses. AB - PURPOSE: To demonstrate how data collected using the computerized planimetric method (CPM) can be analyzed by providing an example in which the amount of plaque accumulation and the efficacy of the rotating needles device (RND) in cleaning specific parts of partial removable dental prostheses (PRDPs) were estimated. MATERIALS AND METHODS: Thirty-four participants wearing a total of 41 double-crown-retained PRDPs with veneered secondary crowns were included in this study. The PRDPs underwent the following steps: preparing the PRDP for photography, photography of the PRDP, cleaning the PRDP with the RND, and re photography. One trained examiner used a tested CPM to analyze 98 images (49 before/49 after). Each participant was considered as a statistical unit; thus, if the participant had two PRDPs, one was randomly selected for analysis. Reliability was tested using intraclass correlation coefficients (ICCs[1, 2]), and nonparametric Wilcoxon signed rank test was used for all comparisons. RESULTS: The intraclass correlation coefficients (images before/after) for both the base and veneer were > 0.9. Wilcoxon signed rank test P value was < .001 for the comparison of plaque accumulation on the base and veneer, estimating the RND's efficacy on both PRDP parts (before/after) and comparing the RND's efficacy on the base and the RND's efficacy on the veneer. CONCLUSIONS: There are different ways to analyze data collected via CPM; thus, it is advisable to provide an explanation for the choice of modeling. Plaque accumulation was significantly greater on the double-crown veneer than on the base. The RND efficacy in cleaning the veneer and the base is significant, but more substantial in cleaning the base. PMID- 29448260 TI - Effect of Coloring of Zirconia Framework and Ceramic Veneer on Adhesion of Interfacial Surfaces Determined Using Three-Point Flexural Bonding Strength: An In Vitro Study. AB - PURPOSE: The aim of this study was to investigate the effect of coloring on the interfacial surface adhesion between a zirconia framework and ceramic veneer using three-point flexural bonding strength. MATERIALS AND METHODS: A total of 40 zirconia bars (Zirlux ST1; DE Healthcare) were cut and divided into two groups of 20 (Groups 1 and 2). The two groups were then further split and divided into four groups of 10 each (Groups 1a, 1b, 2a, and 2b). Groups 1a and 1b tested adhesion of uncolored zirconia and two different shades of ceramic veneer, and Groups 2a and 2b tested adhesion of zirconia colored with two different coloring liquids and one shade of ceramic veneer. RESULTS: Some coloring liquids used to color zirconia can significantly affect the bond strength between zirconia and the veneer, whereas ceramic veneer shades do not influence adhesion. CONCLUSION: Bonding strength between zirconia framework and ceramic veneer is affected by the coloring of the zirconia. PMID- 29448261 TI - Effects of Impression Material, Impression Tray Type, and Type of Partial Edentulism on the Fit of Cobalt-Chromium Partial Denture Frameworks on Initial Clinical Insertion: A Retrospective Clinical Evaluation. AB - PURPOSE: To evaluate the effects of impression material, impression tray type, and type of partial edentulism (ie, Kennedy class) on the accuracy of fit of cobalt-chromium (Co-Cr) partial removable dental prostheses (PRDP) in terms of the number of fabricated frameworks required until the attainment of adequate fit. MATERIALS AND METHODS: Electronic case documentations of 120 partially edentulous patients provided with Co-Cr PRDP treatment for one or both arches were examined. Statistical analyses of data were performed using analysis of variance and Tukey honest significant difference test to compare the relationships between the different factors and the number of frameworks that needed to be fabricated for each patient (alpha = .05). RESULTS: Statistical analysis of data derived from 143 records (69 maxillary and 74 mandibular) revealed no significant correlation between impression material, tray type, or Kennedy class and the number of construction attempts for the pooled or individual arch data (P >= .05). CONCLUSION: In PRDP treatment, alginate can be chosen as a first-choice material, and metal stock trays can be a preferred option for making final impressions to fabricate Co-Cr frameworks. PMID- 29448262 TI - Assessment of Location of the Mandibular Canal: Correlation Between Panoramic and Cone Beam Computed Tomography Measurements. AB - PURPOSE: To compare panoramic and cone beam computed tomography (CBCT) determinations of implant-to-mandibular canal (MC) dimensions in mandibular regions posterior to the mental foramen and to investigate whether factors such as gender, age, region, and vertical dimension influence correlation between the two techniques. MATERIALS AND METHODS: A retrospective analysis was carried out in 64 consecutive adult patients (42 females, 22 males; average age 57.1 +/- 13.3 years) in whom 126 implants were positioned in the posterior segment of the mandible. Implant sites (first premolar, second premolar, first molar, and second molar) were assessed on each panoramic and CBCT radiograph by measuring the distance from the inferior border of the implant to the superior border of the MC. Binary logistic regression analysis was used to compute the odds ratios (ORs) of each implant site for underestimation vs nonunderestimation. Linear regression analysis was performed with CBCT dimension as the dependent variable and panoramic dimension, gender, and age as the independent variables. RESULTS: The mean implant-to-MC dimension was 2.50 +/- 1.31 mm in panoramic radiography and 2.91 +/- 1.62 mm in CBCT. The OR that an implant at the second molar region belonged to the underestimation group was strong (15.1:1) and highly significant (P = .011). If a predictive value of .95 was demanded, the implant-to-MC dimensions had to be overestimated by 2 mm compared to the predicted CBCT dimension. CONCLUSION: This study provides evidence of an underestimation of available vertical bone dimensions for implants in the posterior regions of the mandible when assessed by panoramic radiography. Use of CBCT is therefore recommended for all implant size estimations in this region. PMID- 29448263 TI - Comparison of Coronal Tooth Reductions Resulting from Different Crown Preparations. AB - PURPOSE: The aim of this study was to quantify the coronal tooth structure reductions (CTSRs) resulting from a variety of different types of crown preparations performed by undergraduate dental students in a simulation clinic teaching program. MATERIALS AND METHODS: A total of 76 students each submitted 21 different crown preparations completed on typodont teeth, which were individually weighed and analyzed in relation to whole and sectioned reference teeth to calculate the CTSR resulting from each preparation. RESULTS: The largest CTSR resulted from preparations for porcelain bonded to zirconia crowns (50.6%), followed by those for porcelain bonded to metal (PBM) crowns (44.3%), PBM fixed partial dentures (32.8%), shell crowns (32.5%), and full gold crowns (24.6%). CONCLUSION: A wide range of CTSRs resulted from the different types of crown preparations investigated in this study. The crown preparations performed by the undergraduate students produced more conservative coronal reductions than comparable crown preparations generated under controlled in vitro conditions.

PMID- 29448265 TI - Short-term Postoperative Pain and Swelling Associated with Mini and Standard-Size Implants in the Same Patients. AB - PURPOSE: To assess short-term postoperative pain and swelling after insertion of mini dental implants (MDI) and standard-size implants (SSI) in the same patients at different times. MATERIALS AND METHODS: A convenience sample of 42 patients (22 females, 20 males; 58 to 73 years old) participated. Half of the participants received MDIs first, and the other half received SSIs first. Self-perceived pain and swelling at 1, 3, 5, 7, and 10 days postoperative were assessed using a 0-10 visual analog scale. RESULTS AND CONCLUSION: Flapless MDI insertion led to significantly less intense postoperative pain, less intake of analgesics, and almost no swelling compared to SSI insertion. PMID- 29448266 TI - Zirconia-Reinforced Framework for Maxillary Complete Dentures. AB - PURPOSE: This study introduces a newly developed zirconia complete denture (ZrD) that incorporates a ceria-stabilized zirconia/alumina nano-composite framework fabricated with computer-aided design/computer-aided manufacture (CAD/CAM). MATERIALS AND METHODS: Twenty-nine edentulous patients received either a maxillary ZrD (n = 10) or a maxillary conventional complete denture (CD) (n = 19). Patient satisfaction was evaluated before and 12 months after prosthesis placement using the McGill Denture Satisfaction Instrument. RESULTS: During follow-up periods of up to 2 years, no denture fractures were found in the ZrD or CD group. All aspects of patient satisfaction improved, and no significant group differences were found. CONCLUSION: Within the limitations of this study, it can be concluded that maxillary complete dentures with nano-zirconia frameworks might be an alternative prosthetic treatment option. PMID- 29448267 TI - A Novel Computer-Aided Design/Computer-Assisted Manufacture Method for One-Piece Removable Partial Denture and Evaluation of Fit. AB - PURPOSE: To investigate a computer-aided design/computer-aided manufacturing (CAD/CAM) process for producing one-piece removable partial dentures (RPDs) and to evaluate their fits in vitro. MATERIALS AND METHODS: A total of 15 one-piece RPDs were designed using dental CAD and reverse engineering software and then fabricated with polyetheretherketone (PEEK) using CAM. The gaps between RPDs and casts were measured and compared with traditional cast framework RPDs. RESULTS: Gaps were lower for one-piece PEEK RPDs compared to traditional RPDs. CONCLUSION: One-piece RPDs can be manufactured by CAD/CAM, and their fits were better than those of traditional RPDs. PMID- 29448273 TI - ? PMID- 29448274 TI - ? PMID- 29448275 TI - ?

PMID- 29448281 TI - [Evaluation of Factor Structure and Construct Validity of the 12-Item Short Version of the OPD Structure Questionnaire (OPD-SQS) in Psychosomatic Patients]. AB - BACKGROUND: Screening for personality dysfunction is regarded as increasingly important for treatment planning in clinical settings as this allows to determine specific clinical pathways in an early stage. Recently, the 12-item OPD Structure Questionnaire (OPD-SQS) was developed for this purpose and initial results of the factor structure and validity have been published. This study aimed to investigate and validate the OPD-SQS in further patient samples beyond the team of developers and to provide reference values. METHODS: Data was assessed in psychosomatic outpatients (N=565) and inpatients (N=670) at Charite - Universitatsmedizin Berlin between 2012 and 2016. To examine the factor structure of the OPD-SQS confirmatory factor analyses (CFA) were applied in both samples. To evaluate construct validity, a SKID-II-Interview was performed in N=105 patients and narcissism inventory (NI-90) was completed by N=160 patients. In addition, a range of instruments reflecting emotional, social and physical health were assessed. Bivariate correlations were performed to analyze relations between these instruments and the OPD-SQS. RESULTS: CFAs indicated a good to satisfying fit for the proposed model including 3 factors. A Bifactormodel resulted in very good modelfit. Analyses of construct validity resulted in high positive correlations of OPD-SQS with dimensional SCID-II scores, SKID-II interviews, and NI-90 confirming convergent validity. Results for discriminant validity were heterogeneous. Medium to high correlations were found with a range of instruments including D-CAT (depression), A-CAT (anxiety), S-CAT (stress), and PHQ-15 (somatic symptoms). Subsequent analyses revealed, that the factor self-perception is potentially being influenced by current depression and anxiety. Analyses showed only minor differences of correlations between OPD-SQS subscales and other instruments. CONCLUSIONS: The OPD-SQS seems to be appropriate for screening of personality dysfunction. However, other aspects of psychopathology are gathered in addition. Therefore, further investigation of the patients' personality structure such as an OPD interview may be added in clinical settings. PMID- 29448282 TI - [Significance of Helicobacter pylori Diagnostic in Glaucoma]. AB - Glaucoma is one of the most common causes for blindness worldwide. Even if some risk factors for this disease are known, like increased intraocular pressure or increased age, its pathomechanism is still not fully understood. Multiple studies recently analyzed the role of a Helicobacter pylori infection in the glaucoma pathogenesis. Several studies showed a correlation, while others did not come to this conclusion. In summary, it is very likely that a Helicobacter pylori infection coincides with an increased risk for a primary open-angle or normal tension glaucoma. Still, larger studies, with strict inclusion and exclusion criteria, as well as age-matched control groups, are needed to find out if a Helicobacter pylori infection really leads to a higher risk for glaucoma. PMID- 29448283 TI - [Significance of Endothelin-1 in Glaucoma - a Short Overview]. AB - This review article is focused on the various facets of possible endothelin's role in glaucoma; involvement of endothelin in other ocular, in particular vascular, diseases is not specifically discussed. Endothelin is an ubiquitous molecule that occurs in practically all ocular tissues. Its primary physiological function is regulation of the blood vessel diameter and hence regulation of the blood supply in tissues. It is secreted locally, and exerts its effect also predominantly locally. This limits the value of venous blood sampling for estimation of the endothelin function in a particular patient, or in study cohorts as well. Endothelin is involved in the regulation of intraocular pressure, in the regulation of blood flow and in activation of retinal and optic nerve head astrocytes. All these functions are of high importance when it comes to pathogenesis of glaucoma. Possible future directions for glaucoma treatment should encompass pharmacological antagonism to endothelin, an avenue which is at present hindered by potentially serious side-effects of available endothelin antagonists. PMID- 29448284 TI - [The Keyrole of Multiomics in the Predictive, Preventive and Personalised Medical Approach towards Glaucoma Management]. AB - Glaucoma is the second leading cause of blindness, with altogether about 70 million patients registered worldwide. These facts prompt us to reconsider currently applied concepts in overall glaucoma management. Innovative strategies of predictive, preventive and personalised medicine (PPPM) are expected to considerably improve disease prevention and personalised treatment. The comprehensive PPPM measures include the application of individualised patient profiles, "phenotyping", molecular characterisation of the pre-lesions and disease stages, innovative screening programs, patient stratification, early and predictive diagnosis, targeted prevention, and the creation of personalised treatment algorithms. The main stakeholders are glaucoma-dedicated researchers, ophthalmologists, general practitioners, groups at risk, specialised medical units, affected patients and their family members, insurances, policy makers, and the diagnostic and pharmaceutical industries. Potential beneficiaries include these groups as well as society as a whole, due to financial savings in the healthcare expected. PMID- 29448285 TI - [Risk Factors and Therapeutic Goals for Primary and Secondary Cardiovascular Prevention: Significance for the Glaucoma Patient]. AB - Hypertension, diabetes mellitus and dyslipidaemia are among the most important cardiovascular risk factors. In addition, there is an association with the development and progression of glaucoma. During the last years, there has been an intense discussion concerning optimal treatment goals for these risk factors. Recently, the American Heart Association has defined a blood pressure greater than 130/80 mmHg as hypertension and the European guidelines will follow this definition. These lower blood pressure limits increase the risk for a too strict blood pressure treatment with night values, which might be too low for glaucoma patients. In contrast, the treatment goals for LDL cholesterol should be as low as possible ("the lower the better"). There is a more differentiated picture concerning treatment goals for diabetes mellitus. For elderly patients, which is the main group of the glaucoma patients, a less intense blood sugar reduction is currently recommended with an HbA1c value of above 7%. The present paper summarizes the significance of cardiovascular risk factors and the respective treatment goals for the therapy of patients with glaucoma. PMID- 29448286 TI - [Mitochondrial Dysfunctions and Role of Coenzyme Q10 in Patients with Glaucoma]. AB - Mitochondrial function is closely linked to numerous aspects of eye health. Imbalance between the creation of energy and the development of reactive oxygen species (ROS) seems to be the cause of the development of mitochondrial dysfunctions. As a result of this energy deficit, the level of oxidative stress in the eye tissues increases, leading to numerous ophthalmic impairments. It is important to distinguish between primary mitochondrial eye diseases and secondary mitochondrial changes. Primary mitochondrial eye diseases, for example Leber's hereditary optic atrophy (LHON), retinitis pigmentosa and chronic progressive external ophthalmoplegia are caused by direct damage to mitochondrial function induced by defective genes, either located on mitochondrial DNA (mtDNA) or the DNA of the nucleus (nDNA). In contrast, secondary mitochondrial dysfunctions are caused by environmental factors. In recent years, there has been growing evidence that mitochondrial dysfunctions play an important role in many common eye diseases, such as glaucoma, dry eye, diabetic retinopathy, cataract and age related macular degeneration (AMD). This article summarises current knowledge of mitochondrial dysfunctions and the role of coenzyme Q10 (CoQ10) as a possible treatment option - with a special focus on glaucoma. PMID- 29448287 TI - [Significance of Homocysteine in Glaucoma]. AB - Endothelial dysfunction and vascular dysregulation play a role in the multifactorial pathogenesis of glaucomatous optic nerve atrophy. Hyperhomocysteinemia is a risk factor for endothelial dysfunction and is associated with primary open-angle glaucoma as well as secondary open-angle glaucoma in the pseudoexfoliation syndrome. This paper reviews the literature on the association between homocysteine metabolism and glaucomatous disease and explains the possible role of hyperhomocysteinemia in the pathogenesis and progression of glaucoma. We discuss the role of exogenous modifiable risk factors for the prevention and therapy of glaucoma, as well as modification of these factors by changes in life style, such as weight reduction, changes in nutrition and physical activity. The roles of homocysteine in regulating the extracellular matrix, vasotoxicity, neurodegeneration, and epigenetics are explained. Prevention and therapy of glaucoma by regulation of homocysteine levels are discussed. PMID- 29448288 TI - [APD in First Graders. Which tests discriminate between normal and impaired children?] AB - OBJECTIVE: In a controlled group comparison it was shown for 2nd, 3th and 4th graders that children with auditory processing disorders (APD) could be distinguished from those without (Non-APD) by three to four diagnostic tools. The hit rate was 93.6 % resp. 97.5 % 1, 2. The current study investigated whether such a separation is also possible in first graders. MATERIAL AND METHODS: Performance of 77 first graders in two clinically and diagnostically confirmed groups (n = 40 with APD, mean age: 6.93, SD 0.53 yrs; n = 37 Non APD, mean age: 6.90, SD 0.52 yrs) in 8 auditory processing tests of an eclectic test battery were compared (Dichotic Words Test; Phoneme Discrimination and Phoneme Identification; Word-Understanding in Background Noise; Binaural Summation Word Test; Sound Blending; Auditory Sequential Memory of Digits; Nonword Repetition). RESULTS: A differentiation of each clinical group with a multivariate statistical tool (discriminant analysis) functioned successfully. Children with APD were significantly distinguished from unimpaired children with an accuracy of 94.8 % (cross-validated in 92.2 %) via four test variables: (1) Auditory Sequential Memory of digits; (2) Phoneme Discrimination; (3) Nonword Repetition; (4) Word Understanding in Background Noise. CONCLUSIONS: The quality of the diagnostic a priori-grouping using a multivariate statistics (discriminant analysis) could be confirmed for first graders too. PMID- 29448289 TI - Lessons from pathological analysis of recurrent early esophageal squamous cell neoplasia after complete endoscopic radiofrequency ablation. AB - BACKGROUND: Endoscopic radiofrequency ablation (RFA) is a treatment option for early esophageal squamous cell neoplasia (ESCN); however, long-term follow-up studies are lacking. The risks of local recurrence and "buried cancer" are also uncertain. METHODS: Patients with flat-type ESCN who were treated with balloon type +/- focal-type RFA were consecutively enrolled. Follow-up endoscopy was performed at 1, 3, and 6 months, and then every 6 months thereafter. Endoscopic resection was performed for persistent and recurrent ESCN, and the histopathology of resected specimens was assessed. RESULTS: A total of 35 patients were treated with RFA, of whom 30 (86 %) achieved a complete response, three were lost to follow-up, and five (14 %) developed post-RFA stenosis. Two patients had persistent ESCN and received further endoscopic resection, in which the resected specimens all revealed superficial submucosal invasive cancer. Six of the 30 patients with successful RFA (20 %) developed a total of seven episodes of local recurrence (mean size 1.4 cm) during the follow-up period (mean 40.1 months), all of which were successfully resected endoscopically without adverse events. Histological analysis of the resected specimens revealed that six (86 %) had esophageal glandular ductal involvement, all of which extended deeper than the muscularis mucosae layer. Immunohistochemistry staining for P53 and Ki67 suggested a clonal relationship between the ductal involvement and epithelial cells. None of the tumors extended out of the ductal structure; no cases of cancer buried beneath the normal neosquamous epithelium were found. CONCLUSIONS: Because ductal involvement is not uncommon and may be related to recurrence, the use of RFA should be conservative and may not be the preferred primary treatment for early ESCN. PMID- 29448290 TI - Characterization of Severe Arterial Phase Respiratory Motion Artifact on Gadoxetate Disodium-Enhanced MRI - Assessment of Interrater Agreement and Reliability. AB - PURPOSE: To assess the interrater agreement and reliability of experienced abdominal radiologists in the characterization and grading of arterial phase gadoxetate disodium-related respiratory motion artifact on liver MRI. MATERIALS AND METHODS: This prospective multicenter study was initiated by the working group for abdominal imaging within the German Roentgen Society (DRG), and approved by the local IRB of each participating center. 11 board-certified radiologists independently reviewed 40 gadoxetate disodium-enhanced liver MRI datasets. Motion artifacts in the arterial phase were assessed on a 5-point scale. Interrater agreement and reliability were calculated using the intraclass correlation coefficient (ICC) and Kendall coefficient of concordance (W), with p < 0.05 deemed significant. RESULTS: The ICC for interrater agreement and reliability were 0.983 (CI 0.973 - 0.990) and 0.985 (CI 0.978 - 0.991), respectively (both p < 0.0001), indicating excellent agreement and reliability. Kendall's W for interrater agreement was 0.865. A severe motion artifact, defined as a mean motion score >= 4 in the arterial phase was observed in 12 patients. In these specific cases, a motion score >= 4 was assigned by all readers in 75 % (n = 9/12 cases). CONCLUSION: Differentiation and grading of arterial phase respiratory motion artifact is possible with a high level of inter-/intrarater agreement and interrater reliability, which is crucial for assessing the incidence of this phenomenon in larger multicenter studies. KEY POINTS: . Inter and intrarater agreement for motion artifact scoring is excellent among experienced readers.. . Interrater reliability for motion artifact scoring is excellent among experienced readers.. . Characterization of severe motion artifacts proved feasible in this multicenter study..

AB - INTRODUCTION: To assess the impact of changing from general to subspecialized reporting on turnaround time of radiology reports (TAT), the fraction of radiology reports available within 24 hours (R< 24 h) and productivity. MATERIALS AND METHODS: Reporting workflow in our radiology department was changed from general reporting (radiologists report imaging studies of all areas [neuroradiological, abdominal, musculoskeletal imaging et cetera]) to subspecialized reporting (radiologists solely report imaging studies of their subspecialty field [e. g. musculoskeletal]). TAT, R< 24 h and productivity were calculated for a 12-month period of general reporting (January-December 2012) and compared to a 12-month period of subspecialized reporting (April 2014-March 2015) using Mann Whitney U-test, Pearson chi-square test and odds ratios, respectively. RESULTS: Report TAT decreased from a median of 17:04 hours (h) during general reporting to 3:38 h during subspecialized reporting, resulting in a 4.7-fold improvement (p < 0.001). R< 24 h improved significantly from 65 % to 87 % (p < 0.001). The odds of a radiology report being available < 24 h was 3.6- fold higher during subspecialized compared to general reporting. Productivity increased from a median of 301 to 376 (reports/full-time radiologist/month) (p = 0.001). CONCLUSION: Changing the workflow from general to subspecialized reporting significantly improved the turnaround time of radiology reports, the fraction of radiology reports available within 24 hours and productivity. KEY POINTS: . Changing the radiology reporting workflow from general to subspecialized reporting is feasible.. . Implementation of subspecialized reporting yielded significant improvement of radiology report turnaround time.. . Implementation of subspecialized reporting substantially increased the fraction of radiology reports available < 24 h.. . Radiologists' productivity increased after changing to subspecialized reporting.. CITATION FORMAT: . Stern C, Boehm T, Seifert B et al.

PMID- 29448292 TI - A Trunk Stabilization Exercise Warm-up May Reduce Ankle Injuries in Junior Soccer Players. AB - The aim of this study was to investigate the efficacy of a trunk stabilization exercise warm-up program in reducing the incidence of lower extremity injuries among male junior soccer players. Two junior soccer teams participated in this study. The intervention (INT) team performed three trunk stabilization exercises before practice sessions and games, while a control (CON) team performed their usual warm-up without trunk exercises. Both teams engaged in regular soccer training and games, and were followed for the incidence of injury. As a result, overall injury incidence rates (IRs) were 2.65 injuries/1,000 h and 4.94 injuries/1,000 h in the INT and CON teams, respectively (incidence rate ratio [IRR]=0.54, 95% confidence interval [CI]=0.32-0.89, p=0.013). The IR of acute injuries was significantly lower in the INT team (1.91 injuries/1,000 h) than in the CON team (4.06 injuries/1,000 h) (IRR=0.47, 95%CI=0.26-0.84, p=0.009). Regarding injury sites, the IRs of ankle injuries in the INT team (0.32 injuries/1,000 h) were significantly lower than that in the CON team (2.28 injuries/1,000 h) (IRR=0.14, 95%CI=0.04-0.47, p<0.001). These results suggest that a warm-up program comprising trunk stabilization exercises alone can prevent acute injuries, especially ankle injuries. PMID- 29448294 TI - Impact of Multidrug Resistance Protein-4 Inhibitors on Modulating Platelet Function and High on-Aspirin Treatment Platelet Reactivity. AB - Platelet multidrug resistance protein 4 (MRP4) plays a modulating role on platelet activation. Platelet function and thrombus formation are impaired in MRP4 knockout mice models, and, among aspirin-treated patients, high on-aspirin residual platelet reactivity (HARPR) positively correlates with MRP4 levels. To better understand the effects of MRP4 on platelet function, the aim of this investigation was to assess the impact of cilostazol-induced inhibition of MRP4 mediated transport and assess aspirin-induced antiplatelet effects and rates of HARPR in human subjects.Cilostazol-dependent inhibition of MRP4-mediated transport was assessed with the release of the fluorescent adduct bimane glutathione and aspirin entrapment. Effect of Cilostazol on cAMP inhibition was evaluated by vasodilator-stimulated phosphoprotein (VASP). Platelet function was studied by collagen and TRAP-6-induced platelet aggregation and secretion.Cilostazol reduced the release of bimane-glutathione and enhanced aspirin entrapment demonstrating an inhibitory effect on MRP4 in platelets. VASP phosphorylation was absent until 10 seconds after addition of cilostazol, and becomes evident after 30 seconds. An inhibitory effect on platelet aggregation and secretion was found in activated platelets, with threshold concentration of agonists, 10 seconds after addition of cilostazol, supporting a role of MRP4 on platelet function that is cAMP independent. Cilostazol effects were also shown in aspirin-treated platelets. A reduction of platelet aggregation and secretion were observed in aspirin-treated patients with HARPR.This study supports the role of MRP4 on modulating platelet function which occurs through cAMP-independent mechanisms. Moreover, inhibition of MRP4 induced by cilostazol enhances aspirin induced antiplatelet effects and reduces HARPR.

AB - Recombinant factor XIII-A2 (rFXIII-A2) was developed for prophylaxis and treatment of bleeds in patients with congenital FXIII A-subunit deficiency. mentorTM2 (NCT00978380), a multinational, open-label, single-arm, multiple-dosing extension to the pivotal mentorTM1 trial, assessed long-term safety and efficacy of rFXIII-A2 prophylaxis in eligible patients (patients with severe [<0.05 IU/mL] congenital FXIII subunit A deficiency) aged >=6 years. Patients received 35 IU/kg rFXIII-A2 (exact dosing) every 28 +/- 2 days for >=52 weeks. Primary endpoint was safety (adverse events including immunogenicity); secondary endpoints were rate of bleeds requiring FXIII treatment, haemostatic response after one 35 IU/kg rFXIII-A2 dose for breakthrough bleeds and withdrawals due to lack of rFXIII-A2 efficacy. Steady-state pharmacokinetic variables were also summarized. Elective surgery was permitted during the treatment period. Sixty patients were exposed to rFXIII-A2; their median age was 26.0 years (range: 7.0-77.0). rFXIII-A2 was well tolerated without any safety concerns. No non-neutralizing or neutralizing antibodies (inhibitors) against FXIII were detected. Mean annualized bleeding rate (ABR) was 0.043/patient-year. Mean spontaneous ABR was 0.011/patient-year. No patients withdrew due to lack of efficacy. Geometric mean FXIII trough level was 0.17 IU/mL. Geometric terminal half-life was 13.7 days. rFXIII-A2 prophylaxis provided sufficient haemostatic coverage for 12 minor surgeries without the need for additional FXIII therapy; eight procedures were performed within 7 days of the patient's last scheduled rFXIII-A2 dose, and four were performed 10 to 21 days after the last dose. PMID- 29448296 TI - alpha2-Macroglobulin Is a Significant In Vivo Inhibitor of Activated Protein C and Low APC:alpha2M Levels Are Associated with Venous Thromboembolism. AB - BACKGROUND: Activated protein C (APC) is a major regulator of thrombin formation. Two major plasma inhibitors form complexes with APC, protein C inhibitor (PCI) and alpha1-antitrypsin (alpha1AT), and these complexes have been quantified by specific enzyme-linked immunosorbent assays (ELISAs). Also, complexes of APC with alpha2-macroglobulin (alpha2M) have been observed by immunoblotting. Here, we report an ELISA for APC:alpha2M complexes in plasma. METHODS: Plasma samples were pre-treated with dithiothreitol and then with iodoacetamide. The detection range of the newly developed APC:alpha2M assay was 0.031 to 8.0 ng/mL of complexed APC. Following infusions of APC in humans and baboons, complexes of APC with alpha2M, PCI and alpha1AT were quantified. These complexes as well as circulating APC were also measured in 121 patients with a history of venous thromboembolism (VTE) and 119 matched controls. RESULTS: In all the in vivo experiments, alpha2M was a significant APC inhibitor. The VTE case-control study showed that VTE patients had significantly lower APC:alpha2M and APC levels than the controls (p < 0.001). Individuals in the lowest quartile of APC:alpha2M or the lowest quartile of APC had approximately four times more VTE risk than those in the highest quartile of APC:alpha2M or of APC. The risk increased for individuals with low levels of both parameters. CONCLUSION: The APC:alpha2M assay reported here may be useful to help monitor the in vivo fate of APC in plasma. In addition, our results show that a low APC:alpha2M level is associated with increased VTE risk.

PMID- 29448297 TI - Anticoagulant Preferences and Concerns among Venous Thromboembolism Patients. AB - BACKGROUND: Warfarin and direct oral anticoagulants (DOACs) are used for the initial treatment and secondary prevention of venous thromboembolism (VTE), and have similar efficacy. Patient concerns and preferences are important considerations when selecting an anticoagulant, yet these are not well studied. METHODS: VTE patients (n = 519) were surveyed from online sources (clotconnect.org, stoptheclot.org and National Blood Clot Alliance Facebook followers [n = 495]) and a haematology clinic in Vermont (n = 24). RESULTS: Patients were 83% females and on average (+/-standard deviation [SD]) 45.7 +/- 13.1 years; 65% self-reported warfarin as their initial VTE treatment and 35% a DOAC. Proportions reporting being extremely concerned about the following outcomes were as follows: recurrent VTE 33%, major bleeding 21%, moderate bleeding 16% and all-cause death 29%. When asked about oral anticoagulant characteristics, patients strongly preferred anticoagulants that are reversible (53%), and for which blood drug levels can be monitored (30%). Lower proportions agreed with statements that regular blood testing is inconvenient (18%), that they are comfortable using the newest drug versus an established drug (15%) and that it is difficult to change their diet to accommodate their anticoagulant (17%). In multivariable-adjusted models, patients tended to have had as their initial treatment, and to currently be taking, the oral anticoagulant option they personally preferred. DISCUSSION: Patients held the greatest concern for recurrent VTE and mortality, regardless of which treatment they were prescribed. Potential weaknesses of warfarin (e.g., dietary restrictions, regular monitoring) were generally not considered onerous, while warfarin's advantages (e.g., ability to monitor) were viewed favourably. PMID- 29448299 TI - Early and late complications in the reconstructed mandible with free fibula flaps. AB - BACKGROUND AND OBJECTIVES: Evaluation of mandibular reconstructions with free fibula flaps. Identification of factors associated with major recipient site complications, that is, necessitating surgical intervention under general anaesthesia. METHODS: Seventy-nine reconstructions were included. The following factors were analyzed: fixation type, number of osteotomies, site of defect (bilateral/unilateral), surgeon, sex, ASA classification, continuous smoking, pathological N-stage, age, defect size, flap ischemic time, and postoperative radiotherapy. Proportional hazards regression was used to test the effect on the time between reconstruction and intervention. RESULTS: Sixty-nine (87%) of the 79 fibula flaps were successful at the last follow-up. Forty-eight major recipient site complications occurred in 41 reconstructions. Nineteen complications required surgical intervention within six weeks and were mostly vascular problems, necessitating immediate intervention. These early complications were associated with defects crossing the midline, with an estimated relative risk of 5.3 (CI 1.1-20, P = 0.01). Twenty-nine complications required surgical intervention more than 6 weeks after the reconstruction. These late complications generally occurred after months or years, and were associated with smoking, with an estimated relative risk of 2.8 (CI 1.0-8.3, P = 0.05). CONCLUSIONS: Fibula flaps crossing the midline have a higher risk of early major recipient site complications than unilateral reconstructions. Smoking increases the risk of late complications. PMID- 29448300 TI - Identification of preoperative factors associated with outcomes following surgical management of intra-abdominal recurrent or metastatic GIST following neoadjuvant tyrosine kinase inhibitor therapy. AB - BACKGROUND: The role of surgical resection in the treatment of patients with metastatic/recurrent gastrointestinal stromal tumors (GIST) is unclear. The aim of this study was to identify preoperative factors associated with oncologic outcomes for recurrent/metastatic GIST after tyrosine kinase inhibitor (TKI) therapy. METHODS: We identified 107 patients with metastatic or recurrent GIST treated with TKIs and surgical resection (2002-2012). Patients that underwent palliative or incomplete resection were excluded. Complete resection was achieved in 87 patients which comprise the analytic cohort. Univariate and multivariate analyses were conducted to identify risk factors for GIST-specific survival (DSS) and time-to-recurrence (TTR). RESULTS: At a median follow-up of 51 months (91 months for survivors), median DSS was 74 months and TTR was 21 months. By univariate analysis, unifocal disease, duration of TKI < 365 days, and no evidence of radiographic progression were associated with improved TTR and DSS. Multivariate Cox regression demonstrated that evidence of radiographic progression was associated with shorter DSS (HR 2.53, 95%CI = 1.27-5.06, P = 0.008) and increased risk of recurrence (HR 3.33, 95%CI = 1.91-5.82, P < 0.001). CONCLUSIONS: Patients with unifocal disease and radiographic evidence of response to TKI therapy may achieve improved oncologic outcomes when complete surgical resection is achieved following treatment with TKI. PMID- 29448301 TI - Histological expression of methionine adenosyl transferase (MAT) 2A as a post surgical prognostic surrogate in patients with hepatocellular carcinoma. AB - BACKGROUND AND OBJECTIVES: Deregulation of methionine adenosyltransferase (MAT) is involved in hepatocarcinogenesis. This study aimed to investigate the prognostic implications of the level of histological MAT1A and MAT2A in patients with resected hepatocellular carcinoma (HCC). METHODS: A total of 210 patients with HCC who underwent curative resection between 2004 and 2011 were included. The levels of MAT proteins were immunohistochemically measured. RESULTS: MAT1A and MAT2A were over-expressed in 134 (63.8%) and 124 (59.1%) of the 210 tumor tissues, respectively. Up-regulation of tumoral MAT1A was independently associated with male gender, and inversely related to tumors >5 cm (adjusted odds ratios [OR] 2.59, P = 0.008, and OR 0.44, P = 0.012, respectively). Enhanced MAT2A expression was significantly related to age >=60 years and serum AFP >200 ng/mL (OR 0.51, P = 0.030; and OR 2.65, P = 0.003; respectively). Tumoral MAT2A over-expression independently predicted an increased rate of recurrence within 1 year after hepatectomy (adjusted hazard ratio [HR] 2.45, P = 0.012), but that was not the case for MAT1A expression (HR 0.90, P = 0.744). High MAT2A was also an independent predictor of early recurrence (HR 2.54, P = 0.034) in the subset of patients without microvascular invasion (n = 155). CONCLUSIONS: Over-expression of MAT2A in HCC may be a useful biomarker for predicting and monitoring tumor recurrence, especially early after hepatic resection. PMID- 29448302 TI - Retroperitoneal laparoscopic adrenalectomy with transient renal artery occlusion for large adrenal tumors (>=8 cm). AB - OBJECTIVES: To analyze our experience in retroperitoneal laparoscopic adrenalectomy (RLA) with transient renal artery occlusion for large adrenal tumors (>=8 cm) and to explore the safety and feasibility of this surgical procedure. METHODS: A retrospective cohort study was conducted with a surgical data review of 18 patients with large adrenal tumors who underwent RLA with transient renal artery occlusion in our hospital. RESULTS: Eighteen patients were treated by RLA with transient occlusion of the renal artery, and none were converted to open adrenalectomy. The renal artery occlusion time, operative time, estimated blood loss, perirenal drainage time, postoperative hospital stay, and postoperative drainage were 7.6 +/- 1.0 min, 176.3 +/- 49.7 min, 247.2 +/- 274.1 mL, 4.1 +/- 1.02 days, 6.3 +/- 1.4 days, and 73.6 +/- 47.9 mL, respectively. No severe complications occurred, with the exception of hemodynamic instability in one patient with a pheochromocytoma and one transfusion during the operation. Only one case of adrenal crisis occurred postoperatively. Pathological examination revealed 9 cases of pheochromocytoma, 6 cases of adrenal myelolipoma, 1 case of adrenal ganglioneuroma, 1 case of hygromata, and 1 case of adrenal teratoma. No recurrence or evidence of metastasis was observed during the 7-to-30 month follow-up period. CONCLUSION: RLA with transient renal artery occlusion is a feasible, effective, and safe treatment for large adrenal tumors (>=8 cm). PMID- 29448304 TI - Neutrophil: Lymphocyte ratio as a method of predicting complications following hepatic resection for colorectal liver metastasis. AB - BACKGROUND AND OBJECTIVES: Approximately 30-50% of patients with colorectal cancer develop liver metastasis for which liver resection is the only hope for potential cure. However, hepatic resection is associated with considerable morbidity. The aim was to detect early complications by utilising the neutrophil: lymphocyte ratio (NLR). METHODS: We performed a retrospective cohort study of patients undergoing hepatic resection at a single institution between 2008 and 2016. Baseline demographics and complications within 30 days following surgery were recorded, with blood tests measured until day 7. Statistical analysis was performed using Mann Whitney and ROC analysis. RESULTS: One hundred eighty-eight operations were included. 47.3% had an associated complication, of which 31.46% were major. The median NLR was 6.31 across the cohort, 5.44 for uncomplicated procedures, 7.0 for complications and 10.65 in major complications. Median NLR was the best parameter for detecting major complications versus minor complications (AUC 0.74) as opposed to lymphocytes (AUC 0.65), neutrophils (AUC 0.60), and CRP (AUC 0.60). The diagnostic ability of NLR increased further when predicting major complications versus an uncomplicated recovery (AUC 0.78), and it was the only significant parameter in the early post-operative period on days 2, 3, and 4 (AUC 0.70, 0.72, and 0.75). CONCLUSIONS: The NLR may have a role in predicting complications following hepatic resection for CLM, and with earlier detection, potentially improving outcomes. PMID- 29448305 TI - Development and validation of a gas chromatography/tandem mass spectrometry method for simultaneous quantitation of several antipsychotics in human plasma and oral fluid. AB - RATIONALE: Antipsychotic drugs are prescription medications used to treat psychotic disorders, such as schizophrenia, schizoaffective disorder, or psychotic depression. With several antipsychotic drugs currently available all over the world, this class of drugs has quickly gained importance in both the clinical and forensic context. This work describes the development and validation of a methodology for the determination of seven antipsychotic drugs in plasma and oral fluid samples. METHODS: The antipsychotic drugs (chlorpromazine, clozapine, haloperidol, olanzapine, quetiapine, cyamemazine and, levomepromazine) were isolated from 0.2 mL of oral fluid and 0.5 mL of plasma using solid-phase extraction (SPE) following analysis by gas chromatography/tandem mass spectrometry (GC/MS/MS). The method was validated according to the international guidelines in terms of selectivity, linearity, accuracy, precision and recovery. RESULTS: The procedure was linear within 2-600 ng/mL (plasma) and 2-400 ng/mL (oral fluid), the intervals varying according to the compound; a mean R2 value of 0.99 was obtained and the calibrator's accuracy (mean relative error) was within a +/-15 % interval for all concentrations. The limits of detection ranged from 1 to 10 ng/mL. Within- and between-run precision and accuracy were acceptable for all studied compounds. The extraction efficiency of the process ranged from 79% to 95%. The method was applied to authentic specimens. CONCLUSIONS: The described method was proven selective and sensitive for the determination of antipsychotics in low sample volumes using SPE and GC/MS/MS. This method was considered suitable not only for routine analysis of patients undergoing antipsychotic treatment (to evaluate compliance), but also in forensic scenarios where the studied compounds may be involved. To the best of our knowledge, this is the first work that reports the determination of antipsychotic drugs in oral fluid using MS/MS. PMID- 29448303 TI - Nomogram predicting the risk of recurrence after curative-intent resection of primary non-metastatic gastrointestinal neuroendocrine tumors: An analysis of the U.S. Neuroendocrine Tumor Study Group. AB - BACKGROUND: The risk of recurrence after resection of non-metastatic gastro entero-pancreatic neuroendocrine tumors (GEP-NET) is poorly defined. We developed/validated a nomogram to predict risk of recurrence after curative intent resection. METHODS: A training set to develop the nomogram and test set for validation were identified. The predictive ability of the nomogram was assessed using c-indices. RESULTS: Among 1477 patients, 673 (46%) were included in the training set and 804 (54%) in y the test set. On multivariable analysis, Ki-67, tumor size, nodal status, and invasion of adjacent organs were independent predictors of DFS. The risk of death increased by 8% for each percentage increase in the Ki-67 index (HR 1.08, 95% CI, 1.05-1.10; P < 0.001). GEP-NET invading adjacent organs had a HR of 1.65 (95% CI, 1.03-2.65; P = 0.038), similar to tumors >=3 cm (HR 1.67, 95% CI, 1.11-2.51; P = 0.014). Patients with 1-3 positive nodes and patients with >3 positive nodes had a HR of 1.81 (95% CI, 1.12-2.87; P = 0.014) and 2.51 (95% CI, 1.50-4.24; P < 0.001), respectively. The nomogram demonstrated good ability to predict risk of recurrence (c-index: training set, 0.739; test set, 0.718). CONCLUSION: The nomogram was able to predict the risk of recurrence and can be easily applied in the clinical setting. PMID- 29448306 TI - ALBI versus Child-Pugh grading systems for liver function in patients with hepatocellular carcinoma. AB - BACKGROUND: The prognostic performance of the albumin-bilirubin (ALBI) grade in hepatocellular carcinoma (HCC) as an objective method of assessing liver function was investigated. METHODS: Data from 2099 patients with HCC in Korea were collected and analyzed retrospectively. The discriminative performance of ALBI grade was compared with Child-Pugh (C-P) grade for different stages or treatments. RESULTS: The median follow up duration was 16.2 months (range: 1.0 124.9). The median survival times were 49.7 months for C-P grade A (65.8%), 12.4 months for C-P grade B (25.5%), and 4.2 months for C-P grade C (8.6%) (P < 0.001). The median survival times were 84.2 months for ALBI grade 1 (32.8%), 25.5 months for ALBI grade 2 (53.5%), and 7.7 months for ALBI grade 3 (13.7%) (P < 0.001). In early UICC stages, ALBI grade showed better discriminative performance than C-P grade. In curative treatments, ALBI grade also showed better discriminative performance than C-P grade (Harrell's C: 0.624 (C-P grade) vs 0.667 [ALBI grade]). CONCLUSIONS: ALBI grade provided better prognostic performance in survival analysis and better distribution of the grades than C-P grade in HCC, suggesting that ALBI grade could be a good alternative grading system for liver function in patients with HCC. PMID- 29448307 TI - Histopathological changes resulting from selective internal radiotherapy (SIRT). AB - BACKGROUND: Selective internal radiotherapy (SIRT) has emerged as an effective therapy for patients with liver malignancies. Here, we report our analysis of histopathological changes in tumors and healthy liver tissue after SIRT and liver resection. Our main intent was to determine if specific histopathological changes occur in tumor and normal liver tissues. METHODS: We identified 17 patients in whom SIRT was applied to achieve liver resectability. Samples were taken from the resected liver tissue. The tumor, tumor peripheries, and tumor-free tissue were examined microscopically. RESULTS: Microspheres were identified in the vascular tumor bed, tumor-free liver, and portal tract. More microspheres were detected in the tumor than in the healthy liver tissue. When the effects of SIRT were analyzed, most patients showed a partial pathological response. Specific histopathological changes could not be described. We did not find any typical signs of radiation-induced hepatitis in healthy liver tissue. CONCLUSIONS: Our findings support the clinical experience of effective tumor control after SIRT together with minimal impairment of healthy liver tissue. The observed histopathological changes suggest that SIRT might play a role in preoperative downsizing of liver malignancies. PMID- 29448308 TI - Perioperative outcomes and survival following neoadjuvant stereotactic body radiation therapy (SBRT) versus intensity-modulated radiation therapy (IMRT) in pancreatic adenocarcinoma. AB - BACKGROUND AND OBJECTIVES: To compare outcomes in patients receiving neoadjuvant stereotactic body radiation therapy (SBRT) with those receiving intensity modulated radiation therapy (IMRT) for pancreatic adenocarcinoma. METHODS: We analyzed patients receiving neoadjuvant SBRT for borderline resectable (BRPC) and locally advanced pancreatic cancer (LAPC) (2012-2016). Differences in baseline characteristics, perioperative outcomes, progression-free survival (PFS), and overall survival (OS) were compared. RESULTS: Seventy-five (82.4%) patients received SBRT and 16 (17.6%) received IMRT. There were no differences in surgical resection rates in the SBRT (n = 38, 50.7%) and IMRT (n = 11, 68.8%) groups (P = 0.188). Among resected patients, there was no difference in postoperative outcomes or pathologic outcomes including lymph node status, margin status, lymphovascular and perineural invasion, or pathologic response to neoadjuvant treatment (P > 0.05). Among all patients, median PFS and OS were 9.9 and 23.5 months in the SBRT group, respectively, and 15.3 and 21.8 months in the IMRT group, respectively (P > 0.05). Similarly, there was no difference in PFS or OS between groups when stratified by BRPC, LAPC, and surgically resected patients (P > 0.05). CONCLUSIONS: In the neoadjuvant setting, SBRT and IMRT appear to have similar rates of resection, perioperative outcomes, and survival outcomes, but additional studies with increased sample size and longer follow up are needed. PMID- 29448309 TI - The value of additional bevacizumab in patients with high-risk stroma-high colon cancer. A study within the QUASAR2 trial, an open-label randomized phase 3 trial. AB - INTRODUCTION: Patients with a high stroma percentage within the primary tumor have a poor prognosis. In this study, we investigate whether anti-angiogenic therapy might improve survival of patients with a stroma-high profile with potentially increased angiogenesis. MATERIALS AND METHODS: Tissue samples of the primary tumor of 965 colon cancer patients participating in the QUASAR2 trial were analyzed for tumor-stroma ratio (TSR). Stroma-high (>50%) and stroma-low (<=50%) groups were evaluated with respect to survival. RESULTS: Disease free survival (DFS) was significantly lower in the stroma-high group (HR 1.53, 95%CI 1.19-1.95, P = 0.001). No difference in DFS was seen with respect to treatment with capecitabine alone (CAP) or capecitabine with bevacizumab (CAPBEV) (Stroma high HR 1.00, 95%CI 0.69-1.46, P = 0.996; stroma-low HR 1.02, 95%CI 0.75-1.41, P = 0.883). A significant difference in survival was seen comparing groups with or without vascular invasion (DFS P < 0.001). A correlation between vascular invasion and stroma-high was seen (chi2 -test P = 0.043). DISCUSSION AND CONCLUSIONS: The TSR confirmed to be a strong prognosticator for disease-free survival in a selected high-risk patient population. No benefit was found in response to treatment with bevacizumab when stratified for TSR. TSR showed to have an additional prognostic value in patients with vascular invasion present in the primary tumor. PMID- 29448310 TI - Liquid chromatography/mass spectrometry-based plasma metabolic profiling study of escitalopram in subjects with major depressive disorder. AB - Liquid chromatography-mass spectrometry (LC-MS) method revealed the plasma metabolite profiles in major depressive disorder patients treated with escitalopram (ECTP) (n = 7). Depression severity was assessed according to the 17 item Hamilton Depression Rating Scale. Metabolic profiles were derived from major depressive disorder subject blood samples collected after ECTP treatment. Blood plasma was separated and processed in order to effectively extract metabolites, which were then analyzed using LC-MS. We identified 19 metabolites and elucidated their structures using LC-tandem MS (LC-MS/MS) combined with elemental compositions derived from accurate mass measurements. We further used online H/D exchange experiments to verify the structural elucidations of each metabolite. Identifying molecular metabolites may provide critical insights into the pharmacological and clinical effects of ECTP treatment and may also provide useful information informing the development of new antidepressant treatments. These detailed plasma metabolite analyses may also be used to identify optimal dose concentrations in psychopharmacotherapeutic treatment through drug monitoring, as well as forming the basis for response predictions in depressed subjects. PMID- 29448311 TI - Enhancing decision-making about adjuvant chemotherapy in early breast cancer following EndoPredict testing. AB - OBJECTIVE: Chemotherapy side-effects can be substantial. There is increasing recognition that some oestrogen receptor positive (ER +ve), human epidermal growth factor receptor 2 negative (HER2 -ve) patients with breast cancer derive no benefit from chemotherapy and experience only iatrogenic harm. Gene expression profiling tests help refine recurrence risk and likely chemotherapy benefit. EndoPredict(r) is one such test, which classifies risks of distant recurrence as low or high in patients treated with surgery and adjuvant endocrine therapy alone. We compared treatment decisions pre-test and post-test results, patients' anxiety, decisional conflict, and oncologists' confidence about the decisions made. METHODS: Fourteen oncologists in 7 UK hospitals saw 149 pts judged to have equivocal indications for chemotherapy. Provisional treatment decisions were recorded then reconsidered when EPClin results were available. Pre-test and post test results, patients completed State/Trait Anxiety Inventories (STAI), and the decisional conflict scale. Oncologists also recorded basic clinical details, their agreement with, and confidence about treatment decisions. RESULTS: Sixty seven percent patients initially prescribed endocrine alone with high risk result upgraded to endocrine+chemotherapy (E + C); 83% prescribed E + C and had low risk scores, downgraded to E. None of 46 patients initially favouring E alone, who were low risk, changed decisions. Oncologists' confidence about decisions was significantly increased following the results (P = 0.002). Patients with downgraded treatment decisions had significantly lower anxiety scores (P = 0.045); those upgraded had increased scores (P = 0.001). Overall decisional conflict and uncertainty fell significantly post-test (P < 0.022). CONCLUSIONS: EndoPredict scores increased oncologists' and patients' decision-making confidence, generally improving the matching of risk with therapy decisions. PMID- 29448312 TI - Prognostic significance of poorly differentiated clusters and tumor budding in colorectal liver metastases. AB - BACKGROUND: Histomorphological features have been described as prognostic factors after resection of colorectal liver metastases (CLM). The objectives of this study were to assess the prognostic significance of tumor budding (TB) and poorly differentiated clusters (PDC) among CLM, and their association with other prognostic factors. METHODS: We evaluated 229 patients who underwent a first resection of CLM. Slides stained by HE were assessed for TB, PDC, tumor border pattern, peritumoral pseudocapsule, peritumoral, and intratumoral inflammatory infiltrate. Lymphatic and portal invasion were evaluated through D2-40 and CD34 antibody. RESULTS: Factors independently associated with poor overall survival were nodules>4 (P = 0.002), presence of PDC G3 (P = 0.007), portal invasion (P = 0.005), and absence of tumor pseudocapsule (P = 0.006). Factors independently associated with disease-free survival included number of nodules>4 (P < 0.001), presence of PDC G3 (P = 0.005), infiltrative border (P = 0.031), portal invasion (P = 0.006), and absent/mild peritumoral inflammatory infiltrate (P = 0.002). PDC and TB were also associated with histological factors, as portal invasion (TB), peritumoral inflammatory infiltration (PDC), infiltrative border, and absence of tumor pseudocapsule (TB and PDC). CONCLUSIONS: This is the first study demonstrating PDC as a prognostic factor in CLM. TB was also a prognostic factor, but it was not an independent predictor of survival. PMID- 29448314 TI - Optimal nonlinear filtering using the finite-volume method. AB - Optimal sequential inference, or filtering, for the state of a deterministic dynamical system requires simulation of the Frobenius-Perron operator, that can be formulated as the solution of a continuity equation. For low-dimensional, smooth systems, the finite-volume numerical method provides a solution that conserves probability and gives estimates that converge to the optimal continuous time values, while a Courant-Friedrichs-Lewy-type condition assures that intermediate discretized solutions remain positive density functions. This method is demonstrated in an example of nonlinear filtering for the state of a simple pendulum, with comparison to results using the unscented Kalman filter, and for a case where rank-deficient observations lead to multimodal probability distributions. PMID- 29448313 TI - Causes of plasma column contraction in surface-wave-driven discharges in argon at atmospheric pressure. AB - In this work we compute the main features of a surface-wave-driven plasma in argon at atmospheric pressure in view of a better understanding of the contraction phenomenon. We include the detailed chemical kinetics dynamics of Ar and solve the mass conservation equations of the relevant neutral excited and charged species. The gas temperature radial profile is calculated by means of the thermal diffusion equation. The electric field radial profile is calculated directly from the numerical solution of the Maxwell equations assuming the surface wave to be propagating in the TM_{00} mode. The problem is considered to be radially symmetrical, the axial variations are neglected, and the equations are solved in a self-consistent fashion. We probe the model results considering three scenarios: (i) the electron energy distribution function (EEDF) is calculated by means of the Boltzmann equation; (ii) the EEDF is considered to be Maxwellian; (iii) the dissociative recombination is excluded from the chemical kinetics dynamics, but the nonequilibrium EEDF is preserved. From this analysis, the dissociative recombination is shown to be the leading mechanism in the constriction of surface-wave plasmas. The results are compared with mass spectrometry measurements of the radial density profile of the ions Ar^{+} and Ar_{2}^{+}. An explanation is proposed for the trends seen by Thomson scattering diagnostics that shows a substantial increase of electron temperature towards the plasma borders where the electron density is small. PMID- 29448315 TI - Lumping of degree-based mean-field and pair-approximation equations for multistate contact processes. AB - Contact processes form a large and highly interesting class of dynamic processes on networks, including epidemic and information-spreading networks. While devising stochastic models of such processes is relatively easy, analyzing them is very challenging from a computational point of view, particularly for large networks appearing in real applications. One strategy to reduce the complexity of their analysis is to rely on approximations, often in terms of a set of differential equations capturing the evolution of a random node, distinguishing nodes with different topological contexts (i.e., different degrees of different neighborhoods), such as degree-based mean-field (DBMF), approximate-master equation (AME), or pair-approximation (PA) approaches. The number of differential equations so obtained is typically proportional to the maximum degree k_{max} of the network, which is much smaller than the size of the master equation of the underlying stochastic model, yet numerically solving these equations can still be problematic for large k_{max}. In this paper, we consider AME and PA, extended to cope with multiple local states, and we provide an aggregation procedure that clusters together nodes having similar degrees, treating those in the same cluster as indistinguishable, thus reducing the number of equations while preserving an accurate description of global observables of interest. We also provide an automatic way to build such equations and to identify a small number of degree clusters that give accurate results. The method is tested on several case studies, where it shows a high level of compression and a reduction of computational time of several orders of magnitude for large networks, with minimal loss in accuracy.

These waves are able to generate a normal stress which contrasts the confining pressure and promotes failure. Here, we study the mechanisms responsible for this wave activation via numerical simulations of a granular fault model. We observe the particles belonging to the percolating backbone, which sustains the stress, to perform synchronized oscillations over ellipticlike trajectories in the fault plane. These oscillations occur at the characteristic frequency of acoustic fluidization. As the applied shear stress increases, these oscillations become perpendicular to the fault plane just before the system fails, opposing the confining pressure, consistently with the acoustic fluidization scenario. The same change of orientation can be induced by external perturbations at the acoustic fluidization frequency. PMID- 29448317 TI - Magnetic flux conservation in an imploding plasma. AB - The theory of magnetic flux conservation is developed for a subsonic plasma implosion and used to describe the magnetic flux degradation in the MagLIF concept [S. A. Slutz et al., Phys. Plasmas 17, 056303 (2010)10.1063/1.3333505]. Depending on the initial magnetic Lewis and Peclet numbers and the electron Hall parameter, the implosion falls into either a superdiffusive regime in which the magnetization decreases or a magnetized regime in which the magnetization increases. Scaling laws for magnetic field, temperature, and magnetic flux losses in the hot spot of radius R are obtained for both regimes. The Nernst velocity convects the magnetic field outwards, pushing it against the liner and enhancing the magnetic field diffusion, thereby reducing the magnetic field compression and degrading the implosion performance. However, in the magnetized regime, the core of the hot spot becomes magnetically insulated and undergoes an ideal adiabatic compression (T~R^{-4/3} compared to T~R^{-2/3} without magnetic field), while the detrimental Nernst term is confined to the outer part of the hot spot. Its effect is drastically reduced, improving the magnetic flux conservation. PMID- 29448318 TI - Original electric-vertex formulation of the symmetric eight-vertex model on the square lattice is fully nonuniversal. AB - The partition function of the symmetric (zero electric field) eight-vertex model on a square lattice can be formulated either in the original "electric" vertex format or in an equivalent "magnetic" Ising-spin format. In this paper, both electric and magnetic versions of the model are studied numerically by using the corner transfer matrix renormalization-group method which provides reliable data. The emphasis is put on the calculation of four specific critical exponents, related by two scaling relations, and of the central charge. The numerical method is first tested in the magnetic format, the obtained dependencies of critical exponents on the model's parameters agree with Baxter's exact solution, and weak universality is confirmed within the accuracy of the method due to the finite size of the system. In particular, the critical exponents eta and delta are constant as required by weak universality. On the other hand, in the electric format, analytic formulas based on the scaling relations are derived for the critical exponents eta_{e} and delta_{e} which agree with our numerical data. These exponents depend on the model's parameters which is evidence for the full nonuniversality of the symmetric eight-vertex model in the original electric formulation. PMID- 29448319 TI - Crossover from three-dimensional to two-dimensional systems in the nonequilibrium zero-temperature random-field Ising model. AB - We present extensive numerical studies of the crossover from three-dimensional to two-dimensional systems in the nonequilibrium zero-temperature random-field Ising model with metastable dynamics. Bivariate finite-size scaling hypotheses are presented for systems with sizes L*L*l which explain the size-driven critical crossover from two dimensions (l=const, L->infinity) to three dimensions (l?L >infinity). A model of effective critical disorder R_{c}^{eff}(l,L) with a unique fitting parameter and no free parameters in the R_{c}^{eff}(l,L->infinity) limit is proposed, together with expressions for the scaling of avalanche distributions bringing important implications for related experimental data analysis, especially in the case of thin three-dimensional systems. PMID- 29448320 TI - Characterization of microscopic deformation through two-point spatial correlation functions. AB - The molecular rearrangements of most fluids under flow and deformation do not directly follow the macroscopic strain field. In this work, we describe a phenomenological method for characterizing such nonaffine deformation via the anisotropic pair distribution function (PDF). We demonstrate how the microscopic strain can be calculated in both simple shear and uniaxial extension, by perturbation expansion of anisotropic PDF in terms of real spherical harmonics. Our results, given in the real as well as the reciprocal space, can be applied in spectrum analysis of small-angle scattering experiments and nonequilibrium molecular dynamics simulations of soft matter under flow. PMID- 29448321 TI - Dynamic instability in the hook-flagellum system that triggers bacterial flicks. AB - Dynamical bending, buckling, and polymorphic transformations of the flagellum are known to affect bacterial motility, but run-reverse-flick motility of monotrichous bacteria also involves the even more flexible hook connecting the flagellum to its rotary motor. Although flick initiation has been hypothesized to involve either static Euler buckling or dynamic bending of the hook, the precise mechanism of flick initiation remains unknown. Here, we find that flicks initiate via a dynamic instability requiring flexibility in both the hook and flagellum. We obtain accurate estimates of forces and torques on the hook that suggest that flicks occur for stresses below the (static) Euler buckling criterion, then provide a mechanistic model for flick initiation that requires combined bending of the hook and flagellum. We calculate the triggering torque-stiffness ratio and find that our predicted onset of dynamic instability corresponds well with experimental observations. PMID- 29448322 TI - Normal modes of weak colloidal gels. AB - The normal modes and relaxation rates of weak colloidal gels are investigated in calculations using different models of the hydrodynamic interactions between suspended particles. The relaxation spectrum is computed for freely draining, Rotne-Prager-Yamakawa, and accelerated Stokesian dynamics approximations of the hydrodynamic mobility in a normal mode analysis of a harmonic network representing several colloidal gels. We find that the density of states and spatial structure of the normal modes are fundamentally altered by long-ranged hydrodynamic coupling among the particles. Short-ranged coupling due to hydrodynamic lubrication affects only the relaxation rates of short-wavelength modes. Hydrodynamic models accounting for long-ranged coupling exhibit a microscopic relaxation rate for each normal mode, lambda that scales as l^{-2}, where l is the spatial correlation length of the normal mode. For the freely draining approximation, which neglects long-ranged coupling, the microscopic relaxation rate scales as l^{-gamma}, where gamma varies between three and two with increasing particle volume fraction. A simple phenomenological model of the internal elastic response to normal mode fluctuations is developed, which shows that long-ranged hydrodynamic interactions play a central role in the viscoelasticity of the gel network. Dynamic simulations of hard spheres that gel in response to short-ranged depletion attractions are used to test the applicability of the density of states predictions. For particle concentrations up to 30% by volume, the power law decay of the relaxation modulus in simulations accounting for long-ranged hydrodynamic interactions agrees with predictions generated by the density of states of the corresponding harmonic networks as well as experimental measurements. For higher volume fractions, excluded volume interactions dominate the stress response, and the prediction from the harmonic network density of states fails. Analogous to the Zimm model in polymer physics, our results indicate that long-ranged hydrodynamic interactions play a crucial role in determining the microscopic dynamics and macroscopic properties of weak colloidal gels. PMID- 29448323 TI - Aspects of diffusion in the stadium billiard. AB - We perform a detailed numerical study of diffusion in the E stadium of Bunimovich, and propose an empirical model of the local and global diffusion for various values of E with the following conclusions: (i) the diffusion is normal for all values of E (<=0.3) and all initial conditions, (ii) the diffusion constant is a parabolic function of the momentum (i.e., we have inhomogeneous diffusion), (iii) the model describes the diffusion very well including the boundary effects, (iv) the approach to the asymptotic equilibrium steady state is exponential, (v) the so-called random model (Robnik et al., 1997) is confirmed to apply very well, (vi) the diffusion constant extracted from the distribution function in momentum space and the one derived from the second moment agree very well. The classical transport time, an important parameter in quantum chaos, is thus determined. PMID- 29448324 TI - Scaling properties of dynamical localization in monochromatically perturbed quantum maps: Standard map and Anderson map. AB - Dynamical localization phenomena of monochromatically perturbed standard map (SM) and Anderson map (AM), which are both identified with a two-dimensional disordered system under suitable conditions, are investigated by the numerical wave-packet propagation. Some phenomenological formula of the dynamical localization length valid for wide range of control parameters are proposed for both SM and AM. For SM the formula completely agree with the experimental formula, and for AM the presence of a new regime of localization is confirmed. These formula can be derived by the self-consistent mean-field theory of Anderson localization on the basis of a new hypothesis for the cut-off length. Transient diffusion in the large limit of the localization length is also discussed. PMID- 29448325 TI - Subsystem eigenstate thermalization hypothesis. AB - Motivated by the qualitative picture of canonical typicality, we propose a refined formulation of the eigenstate thermalization hypothesis (ETH) for chaotic quantum systems. This formulation, which we refer to as subsystem ETH, is in terms of the reduced density matrix of subsystems. This strong form of ETH outlines the set of observables defined within the subsystem for which it guarantees eigenstate thermalization. We discuss the limits when the size of the subsystem is small or comparable to its complement. In the latter case we outline the way to calculate the leading volume-proportional contribution to the von Neumann and Renyi entanglment entropies. Finally, we provide numerical evidence for the proposal in the case of a one-dimensional Ising spin chain. PMID- 29448326 TI - Characterization of maximally random jammed sphere packings. III. Transport and electromagnetic properties via correlation functions. AB - In the first two papers of this series, we characterized the structure of maximally random jammed (MRJ) sphere packings across length scales by computing a variety of different correlation functions, spectral functions, hole probabilities, and local density fluctuations. From the remarkable structural features of the MRJ packings, especially its disordered hyperuniformity, exceptional physical properties can be expected. Here we employ these structural descriptors to estimate effective transport and electromagnetic properties via rigorous bounds, exact expansions, and accurate analytical approximation formulas. These property formulas include interfacial bounds as well as universal scaling laws for the mean survival time and the fluid permeability. We also estimate the principal relaxation time associated with Brownian motion among perfectly absorbing traps. For the propagation of electromagnetic waves in the long-wavelength limit, we show that a dispersion of dielectric MRJ spheres within a matrix of another dielectric material forms, to a very good approximation, a dissipationless disordered and isotropic two-phase medium for any phase dielectric contrast ratio. We compare the effective properties of the MRJ sphere packings to those of overlapping spheres, equilibrium hard-sphere packings, and lattices of hard spheres. Moreover, we generalize results to micro- and macroscopically anisotropic packings of spheroids with tensorial effective properties. The analytic bounds predict the qualitative trend in the physical properties associated with these structures, which provides guidance to more time consuming simulations and experiments. They especially provide impetus for experiments to design materials with unique bulk properties resulting from hyperuniformity, including structural-color and color-sensing applications. PMID- 29448327 TI - Thin structure of the transit time distributions of open billiards. AB - It is known that typical open billiards distribution of transit times is an exponentially decaying function, possibly with a power-law tail. In the paper we show that on small scales some of such distributions change their appearance. These distributions contain a quasiperiodic thin structure, which carries a significant amount of information about the system. Origin and properties of this structure are discussed. PMID- 29448328 TI - Granular response to impact: Topology of the force networks. AB - The impact of an intruder on granular matter leads to the formation of mesoscopic force networks, which were seen particularly clearly in the recent experiments carried out with photoelastic particles [Clark et al., Phys. Rev. Lett. 114, 144502 (2015)PRLTAO0031-900710.1103/PhysRevLett.114.144502]. These force networks are characterized by complex structure and evolve on fast time scales. While it is known that total photoelastic activity in the granular system is correlated with the acceleration of the intruder, it is not known how the structure of the force network evolves during impact, and if there are dominant features in the networks that can be used to describe the intruder's dynamics. Here, we use topological tools, in particular persistent homology, to describe these features. Persistent homology allows quantification of both structure and time evolution of the resulting force networks. We find that there is a clear correlation of the intruder's dynamics and some of the topological measures implemented. This finding allows us to discuss which properties of the force networks are most important when attempting to describe the intruder's dynamics. In particular, we find that the presence of loops in the force network, quantified by persistent homology, is strongly correlated to the deceleration of the intruder. In some cases, particularly for the impact on soft particles, the measures derived from the persistence analysis describe the deceleration of the intruder even better than the total photoelastic activity. We are also able to define an upper bound on the relevant time scale over which the force networks evolve. PMID- 29448329 TI - Minimum energy dissipation required for a logically irreversible operation. AB - According to Landauer's principle, the minimum heat emission required for computing is linked to logical entropy, or logical reversibility. The validity of Landauer's principle has been investigated for several decades and was finally demonstrated in recent experiments by showing that the minimum heat emission is associated with the reduction in logical entropy during a logically irreversible operation. Although the relationship between minimum heat emission and logical reversibility is being revealed, it is not clear how much free energy is required to be dissipated for a logically irreversible operation. In the present study, in order to reveal the connection between logical reversibility and free energy dissipation, we numerically demonstrated logically irreversible protocols using adiabatic superconductor logic. The calculation results of work during the protocol showed that, while the minimum heat emission conforms to Landauer's principle, the free energy dissipation can be arbitrarily reduced by performing the protocol quasistatically. The above results show that logical reversibility is not associated with thermodynamic reversibility, and that heat is not only emitted from logic devices but also absorbed by logic devices. We also formulated the heat emission from adiabatic superconductor logic during a logically irreversible operation at a finite operation speed. PMID- 29448330 TI - Structural behavior of supercritical fluids under confinement. AB - The existence of the Frenkel line in the supercritical regime of a Lennard-Jones (LJ) fluid shown through molecular dynamics (MD) simulations initially and later corroborated by experiments on argon opens up possibilities of understanding the structure and dynamics of supercritical fluids in general and of the Frenkel line in particular. The location of the Frenkel line, which demarcates two distinct physical states, liquidlike and gaslike within the supercritical regime, has been established through MD simulations of the velocity autocorrelation (VACF) and radial distribution function (RDF). We, in this article, explore the changes in the structural features of supercritical LJ fluid under partial confinement using atomistic walls. The study is carried out across the Frenkel line through a series of MD simulations considering a set of thermodynamics states in the supercritical regime (P=5000 bar, 240K<=T<=1500K) of argon well above the critical point. Confinement is partial, with atomistic walls located normal to z and extending to "infinity" along the x and y directions. In the "liquidlike" regime of the supercritical phase, particles are found to be distributed in distinct layers along the z axis with layer spacing less than one atomic diameter and the lateral RDF showing amorphous-like structure for specific spacings (packing frustration) and non-amorphous-like structure for other spacings. Increasing the rigidity of the atomistic walls is found to lead to stronger layering and increased structural order. For confinement with reflective walls, layers are found to form with one atomic diameter spacing and the lateral RDF showing close-packed structure for the smaller confinements. Translational order parameter and excess entropy assessment confirms the ordering taking place for atomistic wall and reflective wall confinements. In the "gaslike" regime of the supercritical phase, particle distribution along the spacing and the lateral RDF exhibit features not significantly different from that due to normal gas regime. The heterogeneity across the Frenkel line, found to be present both in bulk and confined systems, might cause the breakdown of the universal scaling between structure and dynamics of fluids necessitating the determination of a unique relationship between them. PMID- 29448331 TI - Fractional dynamics using an ensemble of classical trajectories. AB - A trajectory-based formulation for fractional dynamics is presented and the trajectories are generated deterministically. In this theoretical framework, we derive a new class of estimators in terms of confluent hypergeometric function (_{1}F_{1}) to represent the Riesz fractional derivative. Using this method, the simulation of free and confined Levy flight are in excellent agreement with the exact numerical and analytical results. In addition, the barrier crossing in a bistable potential driven by Levy noise of index alpha is investigated. In phase space, the behavior of trajectories reveal the feature of Levy flight in a better perspective. PMID- 29448332 TI - Looking for the optimal rate of recombination for evolutionary dynamics. AB - We consider many-site mutation-recombination models of evolution with selection. We are looking for situations where the recombination increases the mean fitness of the population, and there is an optimal recombination rate. We found two fitness landscapes supporting such nonmonotonic behavior of the mean fitness versus the recombination rate. The first case is related to the evolution near the error threshold on a neutral-network-like fitness landscape, for moderate genome lengths and large population. The more realistic case is the second one, in which we consider the evolutionary dynamics of a finite population on a rugged fitness landscape (the smooth fitness landscape plus some random contributions to the fitness). We also give the solution to the horizontal gene transfer model in the case of asymmetric mutations. To obtain nonmonotonic behavior for both mutation and recombination, we need a specially designed (ideal) fitness landscape. PMID- 29448333 TI - Absolute and convective instabilities of a film flow down a vertical fiber subjected to a radial electric field. AB - We consider the motion of a gravity-driven flow down a vertical fiber subjected to a radial electric field. This flow exhibits rich dynamics including the formation of droplets, or beads, driven by a Rayleigh-Plateau mechanism modified by the presence of gravity as well as the Maxwell stress at the interface. A spatiotemporal stability analysis is performed to investigate the effect of electric field on the absolute-convective instability (AI-CI) characteristics. We performed a numerical simulation on the nonlinear evolution of the film to examine the transition from CI to AI regime. The numerical results are in excellent agreement with the spatiotemporal stability analysis. The blowup behavior of nonlinear simulation predicts the formation of touchdown singularity of the interface due to the effect of electric field. We try to connect the blowup behavior with the AI-CI characteristics. It is found that the singularities mainly occur in the AI regime. The results indicate that the film may have a tendency to form very sharp tips due to the enhancement of the absolute instability induced by the electric field. We perform a theoretical analysis to study the behaviors of the singularities. The results show that there exists a self-similarity between the temporal and spatial distances from the singularities. PMID- 29448334 TI - Metastable states and energy flow pathway in square graphene resonators. AB - Nonlinear interaction between flexural modes is critical to heat conductivity and mechanical vibration of two-dimensional materials such as graphene. Much effort has been devoted to understand the underlying mechanism. In this paper, we examine solely the out-of-plane flexural modes and identify their energy flow pathway during thermalization process. The key is the development of a universal scheme that numerically characterizes the strength of nonlinear interactions between normal modes. In particular, for our square graphene system, the modes are grouped into four classes by their distinct symmetries. The couplings are significantly larger within a class than between classes. As a result, the equations for the normal modes in the same class as the initially excited one can be approximated by driven harmonic oscillators, therefore, they get energy almost instantaneously. Because of the hierarchical organization of the mode coupling, the energy distribution among the modes will arrive at a stable profile, where most of the energy is localized on a few modes, leading to the formation of "natural package" and metastable states. The dynamics for modes in other symmetry classes follows a Mathieu type of equation, thus, interclass energy flow, when the initial excitation energy is small, starts typically when there is a mode that lies in the unstable region in the parameter space of Mathieu equation. Due to strong coupling of the modes inside the class, the whole class will get energy and be lifted up by the unstable mode. This characterizes the energy flow pathway of the system. These results bring fundamental understandings to the Fermi-Pasta Ulam problem in two-dimensional systems with complex potentials, and reveal clearly the physical picture of dynamical interactions between the flexural modes, which will be crucial to the understanding of their abnormal contribution to heat conduction and nonlinear mechanical vibrations. PMID- 29448335 TI - Zealots in the mean-field noisy voter model. AB - The influence of zealots on the noisy voter model is studied theoretically and numerically at the mean-field level. The noisy voter model is a modification of the voter model that includes a second mechanism for transitions between states: Apart from the original herding processes, voters may change their states because of an intrinsic noisy-in-origin source. By increasing the importance of the noise with respect to the herding, the system exhibits a finite-size phase transition from a quasiconsensus state, where most of the voters share the same opinion, to one with coexistence. Upon introducing some zealots, or voters with fixed opinion, the latter scenario may change significantly. We unveil new situations by carrying out a systematic numerical and analytical study of a fully connected network for voters, but allowing different voters to be directly influenced by different zealots. We show that this general system is equivalent to a system of voters without zealots, but with heterogeneous values of their parameters characterizing herding and noisy dynamics. We find excellent agreement between our analytical and numerical results. Noise and herding or zealotry acting together in the voter model yields a nontrivial mixture of the scenarios with the two mechanisms acting alone: It represents a situation where the global-local (noise-herding) competition is coupled to a symmetry breaking (zealots). In general, the zealotry enhances the effective noise of the system, which may destroy the original quasiconsensus state, and can introduce a bias towards the opinion of the majority of zealots, hence breaking the symmetry of the system and giving rise to new phases. In the most general case we find two different transitions: a discontinuous transition from an asymmetric bimodal phase to an extreme asymmetric phase and a second continuous transition from the extreme asymmetric phase to an asymmetric unimodal phase. PMID- 29448336 TI - Synchronization in networks with heterogeneous coupling delays. AB - Synchronization in networks of identical oscillators with heterogeneous coupling delays is studied. A decomposition of the network dynamics is obtained by block diagonalizing a newly introduced adjacency lag operator which contains the topology of the network as well as the corresponding coupling delays. This generalizes the master stability function approach, which was developed for homogenous delays. As a result the network dynamics can be analyzed by delay differential equations with distributed delay, where different delay distributions emerge for different network modes. Frequency domain methods are used for the stability analysis of synchronized equilibria and synchronized periodic orbits. As an example, the synchronization behavior in a system of delay coupled Hodgkin-Huxley neurons is investigated. It is shown that the parameter regions where synchronized periodic spiking is unstable expand when increasing the delay heterogeneity. PMID- 29448337 TI - Accurate analytic solution of chemical master equations for gene regulation networks in a single cell. AB - Studying gene regulation networks in a single cell is an important, interesting, and hot research topic of molecular biology. Such process can be described by chemical master equations (CMEs). We propose a Hamilton-Jacobi equation method with finite-size corrections to solve such CMEs accurately at the intermediate region of switching, where switching rate is comparable to fast protein production rate. We applied this approach to a model of self-regulating proteins [H. Ge et al., Phys. Rev. Lett. 114, 078101 (2015)PRLTAO0031 900710.1103/PhysRevLett.114.078101] and found that as a parameter related to inducer concentration increases the probability of protein production changes from unimodal to bimodal, then to unimodal, consistent with phenotype switching observed in a single cell. PMID- 29448338 TI - Thin film modeling of crystal dissolution and growth in confinement. AB - We present a continuum model describing dissolution and growth of a crystal contact confined against a substrate. Diffusion and hydrodynamics in the liquid film separating the crystal and the substrate are modeled within the lubrication approximation. The model also accounts for the disjoining pressure and surface tension. Within this framework, we obtain evolution equations which govern the nonequilibrium dynamics of the crystal interface. Based on this model, we explore the problem of dissolution under an external load, known as pressure solution. We find that in steady state, diverging (power-law) crystal-surface repulsions lead to flat contacts with a monotonic increase of the dissolution rate as a function of the load. Forces induced by viscous dissipation then surpass those due to disjoining pressure at large enough loads. In contrast, finite repulsions (exponential) lead to sharp pointy contacts with a dissolution rate independent of the load and the liquid viscosity. Ultimately, in steady state, the crystal never touches the substrate when pressed against it. This result is independent from the nature of the crystal-surface interaction due to the combined effects of viscosity and surface tension. PMID- 29448339 TI - Cooperative behavior of molecular motions giving rise to two glass transitions in the same supercooled mesophase of a smectogenic liquid crystal dimer. AB - In the present work, a detailed analysis of the glassy behavior and the relaxation dynamics of the liquid crystal dimer alpha-(4-cyanobiphenyl-4'-yloxy) omega-(1-pyrenimine-benzylidene-4'-oxy) heptane (CBO7O.Py) throughout both nematic and smectic-A mesophases by means of broadband dielectric spectroscopy has been performed. CBO7O.Py shows three different dielectric relaxation modes and two glass transition (T_{g}) temperatures: The higher T_{g} is due to the freezing of the molecular motions responsible for the relaxation mode with the lowest frequency (MU_{1L}); the lower T_{g} is due to the motions responsible for the two relaxation modes with highest frequencies (MU_{1H} and MU_{2}), which converge just at their corresponding T_{g}. It is shown how the three modes follow a critical-like description via the dynamic scaling model. The two modes with lowest frequencies (MU_{1L} and MU_{1H}) are cooperative in the whole range of the mesophases, whereas the highest frequency mode (MU_{2}) is cooperative just below some crossover temperature. In terms of fragility, at the glass transition, the ensemble (MU_{1H}+MU_{2}) presents a value of the steepness index and MU_{1L} a different one, meaning that fragility is a property intrinsic to the molecular motion itself. Finally, the steepness index seems to have a universal behavior with temperature for the dielectric relaxation modes of liquid crystal dimers, being almost constant at high temperatures and increasing drastically when cooling the compound down to the glass transition from a temperature about 3/4T_{NI}. PMID- 29448340 TI - Breathing pulses in the damped-soliton model for nerves. AB - Unlike the Hodgkin-Huxley picture in which the nerve impulse results from ion exchanges across the cell membrane through ion-gate channels, in the so-called soliton model the impulse is seen as an electromechanical process related to thermodynamical phenomena accompanying the generation of the action potential. In this work, account is taken of the effects of damping on the nerve impulse propagation, within the framework of the soliton model. Applying the reductive perturbation expansion on the resulting KdV-Burgers equation, a damped nonlinear Schrodinger equation is derived and shown to admit breathing-type solitary wave solutions. Under specific constraints, these breathing pulse solitons become self trapped structures in which the damping is balanced by nonlinearity such that the pulse amplitude remains unchanged even in the presence of damping. PMID- 29448341 TI - Interstitial micelles in binary blends of ABA triblock copolymers and homopolymers. AB - We investigate triblock-homopolymer blends of types A1BA2/A and A1BA2/B, using a lattice Monte Carlo method. While the simulated triblock chains are compositionally symmetric in terms of the A-to-B volume ratio, the A1 block is significantly shorter than the A2 block. For the pure A1BA2 melt and the A1BA2 solutions in selective solvent the phase behavior is relatively well known, including existence and stability of the interstitial micelles which were discovered in previous Monte Carlo simulations. In this paper we study the stability of the interstitial micelles as a function of triblock volume fraction in selective homopolymers of either type A or type B, using two significantly different homopolymer chain lengths. We found that adding selective homopolymer of type A shifts the stability of the interstitial micelles into significantly higher temperatures. We also obtained, via self-assembly, intriguing new nanostructures which can be identified as ordered truncated octahedra. Finally, we established that the phase behavior of the triblock-homopolymer blends depends relatively weakly on the chain length of the added homopolymer. PMID- 29448342 TI - Heterogeneous continuous-time random walks. AB - We introduce a heterogeneous continuous-time random walk (HCTRW) model as a versatile analytical formalism for studying and modeling diffusion processes in heterogeneous structures, such as porous or disordered media, multiscale or crowded environments, weighted graphs or networks. We derive the exact form of the propagator and investigate the effects of spatiotemporal heterogeneities onto the diffusive dynamics via the spectral properties of the generalized transition matrix. In particular, we show how the distribution of first-passage times changes due to local and global heterogeneities of the medium. The HCTRW formalism offers a unified mathematical language to address various diffusion reaction problems, with numerous applications in material sciences, physics, chemistry, biology, and social sciences. PMID- 29448343 TI - Mutual influence of molecular diffusion in gas and surface phases. AB - We develop molecular transport simulation methods that simultaneously deal with gas- and surface-phase diffusions to determine the effect of surface diffusion on the overall diffusion coefficients. The phenomenon of surface diffusion is incorporated into the test particle method and the mean square displacement method, which are typically employed only for gas-phase transport. It is found that for a simple cylindrical pore, the diffusion coefficients in the presence of surface diffusion calculated by these two methods show good agreement. We also confirm that both methods reproduce the analytical solution. Then, the diffusion coefficients for ink-bottle-shaped pores are calculated using the developed method. Our results show that surface diffusion assists molecular transport in the gas phase. Moreover, the surface tortuosity factor, which is known to be uniquely determined by physical structure, is influenced by the presence of gas phase diffusion. This mutual influence of gas-phase diffusion and surface diffusion indicates that their simultaneous calculation is necessary for an accurate evaluation of the diffusion coefficients. PMID- 29448344 TI - Multiple eigenmodes of the Rayleigh-Taylor instability observed for a fluid interface with smoothly varying density. AB - In this article, multiple eigen-systems including linear growth rates and eigen functions have been discovered for the Rayleigh-Taylor instability (RTI) by numerically solving the Sturm-Liouville eigen-value problem in the case of two dimensional plane geometry. The system called the first mode has the maximal linear growth rate and is just extensively studied in literature. Higher modes have smaller eigen-values, but possess multi-peak eigen-functions which bring on multiple pairs of vortices in the vorticity field. A general fitting expression for the first four eigen-modes is presented. Direct numerical simulations show that high modes lead to appearances of multi-layered spike-bubble pairs, and lots of secondary spikes and bubbles are also generated due to the interactions between internal spikes and bubbles. The present work has potential applications in many research and engineering areas, e.g., in reducing the RTI growth during capsule implosions in inertial confinement fusion. PMID- 29448345 TI - Route from discreteness to the continuum for the Tsallis q-entropy. AB - The existence and exact form of the continuum expression of the discrete nonlogarithmic q-entropy is an important open problem in generalized thermostatistics, since its possible lack implies that nonlogarithmic q-entropy is irrelevant for the continuous classical systems. In this work, we show how the discrete nonlogarithmic q-entropy in fact converges in the continuous limit and the negative of the q-entropy with continuous variables is demonstrated to lead to the (Csiszar type) q-relative entropy just as the relation between the continuous Boltzmann-Gibbs expression and the Kullback-Leibler relative entropy. As a result, we conclude that there is no obstacle for the applicability of the q entropy to the continuous classical physical systems. PMID- 29448346 TI - Exceptional points near first- and second-order quantum phase transitions. AB - We study the impact of quantum phase transitions (QPTs) on the distribution of exceptional points (EPs) of the Hamiltonian in the complex-extended parameter domain. Analyzing first- and second-order QPTs in the Lipkin-Meshkov-Glick model we find an exponentially and polynomially close approach of EPs to the respective critical point with increasing size of the system. If the critical Hamiltonian is subject to random perturbations of various kinds, the averaged distribution of EPs close to the critical point still carries decisive information on the QPT type. We therefore claim that properties of the EP distribution represent a parametrization-independent signature of criticality in quantum systems. PMID- 29448347 TI - Analyzing a stochastic process driven by Ornstein-Uhlenbeck noise. AB - A scalar Langevin-type process X(t) that is driven by Ornstein-Uhlenbeck noise eta(t) is non-Markovian. However, the joint dynamics of X and eta is described by a Markov process in two dimensions. But even though there exists a variety of techniques for the analysis of Markov processes, it is still a challenge to estimate the process parameters solely based on a given time series of X. Such a partially observed 2D process could, e.g., be analyzed in a Bayesian framework using Markov chain Monte Carlo methods. Alternatively, an embedding strategy can be applied, where first the joint dynamics of X and its temporal derivative X[over ] is analyzed. Subsequently, the results can be used to determine the process parameters of X and eta. In this paper, we propose a more direct approach that is purely based on the moments of the increments of X, which can be estimated for different time-increments tau from a given time series. From a stochastic Taylor expansion of X, analytic expressions for these moments can be derived, which can be used to estimate the process parameters by a regression strategy.

AB - In this work, we show that a universal quantum work relation for a quantum system driven arbitrarily far from equilibrium extends to a parity-time- (PT-) symmetric quantum system with unbroken PT symmetry, which is a consequence of microscopic reversibility. The quantum Jarzynski equality, linear response theory, and Onsager reciprocal relations for the PT-symmetric quantum system are recovered as special cases of the universal quantum work relation in a PT-symmetric quantum system. In the regime of broken PT symmetry, the universal quantum work relation does not hold because the norm is not preserved during the dynamics.

AB - We study the scattering problem at generalized Cantor-like potentials characterized by the expansion rate a and duplication number N, and derive an exact formula of transmittance. It was found that the transmittance is expressed with Chebyshev polynomials of the second kind, and the multifractality of the reflectance varies depending on a and N. PMID- 29448351 TI - Experimental investigation of the glass transition of polystyrene thin films in a broad frequency range. AB - In this study, we investigate the alpha process of a polystyrene thin film using inelastic neutron scattering (INS), dielectric relaxation spectroscopy (DRS), and thermal expansion spectroscopy (TES). The DRS and TES measurements exhibited a decrease in glass transition temperature (T_{g}) with film thickness. On the other hand, an increase in T_{g} was observed in INS studies. In order to interpret this contradiction, we investigated the temperature dependence of the peak frequency (f_{m}) of the alpha process probed by DRS and TES. The experiments revealed an increase in the peak frequency (f_{m}) with decreasing film thickness in the frequency region. This observation is consistent with the observed decrease in T_{g} with thickness. Interestingly, the increase in T_{g} with film thickness was confirmed by fitting the temperature dependence measurements of the peak frequency with the Vogel-Fulcher-Tammann equation, within the frequency region probed by INS. The discrepancy between INS and DRS or TES descriptions of the alpha process is likely to be attributed to a decrease in the apparent activation energy with film thickness and reduced mobility, due to the impenetrable wall effect.

AB - Cilia are elastic hairlike protuberances of the cell membrane found in various unicellular organisms and in several tissues of most living organisms. In some tissues such as the airway tissues of the lung, the coordinated beating of cilia induces a fluid flow of crucial importance as it allows the continuous cleaning of our bronchia, known as mucociliary clearance. While most of the models addressing the question of collective dynamics and metachronal wave consider homogeneous carpets of cilia, experimental observations rather show that cilia clusters are heterogeneously distributed over the tissue surface. The purpose of this paper is to investigate the role of spatial heterogeneity on the coherent beating of cilia using a very simple one-dimensional model for cilia known as the rower model. We systematically study systems consisting of a few rowers to hundreds of rowers and we investigate the conditions for the emergence of collective beating. When considering a small number of rowers, a phase drift occurs, hence, a bifurcation in beating frequency is observed as the distance between rower clusters is changed. In the case of many rowers, a distribution of frequencies is observed. We found in particular the pattern of the patchy structure that shows the best robustness in collective beating behavior, as the density of cilia is varied over a wide range. PMID- 29448352 TI - Insensitivity of active nematic liquid crystal dynamics to topological constraints. AB - Confining a liquid crystal imposes topological constraints on the orientational order, allowing global control of equilibrium systems by manipulation of anchoring boundary conditions. In this article, we investigate whether a similar strategy allows control of active liquid crystals. We study a hydrodynamic model of an extensile active nematic confined in containers, with different anchoring conditions that impose different net topological charges on the nematic director. We show that the dynamics are controlled by a complex interplay between topological defects in the director and their induced vortical flows. We find three distinct states by varying confinement and the strength of the active stress: A topologically minimal state, a circulating defect state, and a turbulent state. In contrast to equilibrium systems, we find that anchoring conditions are screened by the active flow, preserving system behavior across different topological constraints. This observation identifies a fundamental difference between active and equilibrium materials. PMID- 29448353 TI - Compression-driven jamming of athermal frictionless spherocylinders in two dimensions. AB - We simulate numerically the compression-driven jamming of athermal, frictionless, soft-core spherocylinders in two dimensions, for a range of particle aspect ratios alpha. We find the critical packing fraction phi_{J}(alpha) for the jamming transition and the average number of contacts per particle z_{J}(alpha) at jamming. We find that both are nonmonotonic, with a peak at alpha~1. We find that configurations at the compression-driven jamming point are always hypostatic for all alpha, with z_{J}phi_{J}. We consider the extended versus localized nature of these low frequency modes, and the extent to which they involve translational or rotational motion, and find many low frequency sliding modes where particles can move with little rotation. We highlight the importance of treating side-to-side contacts, along flat sides of the spherocylinder, properly for the correct determination of z_{J}. We note the singular nature of taking the alpha->0 limit. We discuss the similarities and differences with previous work on jammed ellipses and ellipsoids, to illustrate the effects that different particle shapes have on configurations at jamming.

AB - Widely regarded as an interesting model system for studying flow properties of blood, vesicles are closed membranes of phospholipids that mimic the cytoplasmic membranes of red blood cells. In this study we analyze the rheology of a suspension of vesicles in a confined geometry: the suspension, bound by two planar rigid walls on each side, is subject to a shear flow. Flow properties are then analyzed as a function of shear rate gamma[over ], the concentration of the suspension phi, and the viscosity contrast lambda=eta_{in}/eta_{out}, where eta_{in} and eta_{out} are the fluid viscosities of the inner and outer fluids, respectively. We find that the apparent (or effective viscosity) of the suspension exhibits both shear thinning (decreasing viscosity with shear rate) or shear thickening (increasing viscosity with shear rate) in the same concentration range. The shear thinning or thickening behaviors appear as subtle phenomena, dependant on viscosity contrast lambda. We provide physical arguments on the origins of these behaviors. PMID- 29448355 TI - Binding constant of cell adhesion receptors and substrate-immobilized ligands depends on the distribution of ligands. AB - Cell-cell adhesion and the adhesion of cells to tissues and extracellular matrix, which are pivotal for immune response, tissue development, and cell locomotion, depend sensitively on the binding constant of receptor and ligand molecules anchored on the apposing surfaces. An important question remains of whether the immobilization of ligands affects the affinity of binding with cell adhesion receptors. We have investigated the adhesion of multicomponent membranes to a flat substrate coated with immobile ligands using Monte Carlo simulations of a statistical mesoscopic model with biologically relevant parameters. We find that the binding of the adhesion receptors to ligands immobilized on the substrate is strongly affected by the ligand distribution. In the case of ligand clusters, the receptor-ligand binding constant can be significantly enhanced due to the less translational entropy loss of lipid-raft domains in the model cell membranes upon the formation of additional complexes. For ligands randomly or uniformly immobilized on the substrate, the binding constant is rather decreased since the receptors localized in lipid-raft domains have to pay an energetic penalty in order to bind ligands. Our findings help to understand why cell-substrate adhesion experiments for measuring the impact of lipid rafts on the receptor ligand interactions led to contradictory results. PMID- 29448356 TI - Two- and three-point functions at criticality: Monte Carlo simulations of the improved three-dimensional Blume-Capel model. AB - We compute two- and three-point functions at criticality for the three dimensional Ising universality class. To this end, we simulate the improved Blume Capel model at the critical temperature on lattices of a linear size up to L=1600. As a check, also simulations of the spin-1/2 Ising model are performed. We find f_{sigmasigmaepsilon}=1.051(1) and f_{epsilonepsilonepsilon}=1.533(5) for operator product expansion coefficients. These results are consistent with but less precise than those recently obtained by using the bootstrap method. An important ingredient in our simulations is a variance reduced estimator of N point functions. Finite size corrections vanish with L^{-Delta_{epsilon}}, where L is the linear size of the lattice and Delta_{epsilon} is the scaling dimension of the leading Z_{2}-even scalar epsilon. PMID- 29448357 TI - Oscillating decorated interfaces in parametrically driven systems. AB - Macroscopic systems forced by the temporal modulation of their parameters exhibit complex interfaces between symmetric states. Here we investigate the origin of the transition from a flat to an oscillating decorated interface. Based on a model that describes a magnetic plane under the influence of an oscillating magnetic field and an extended Josephson junction under the influence of an alternating current, we derive a simple model that accounts for the interface dynamics. Analytically this model allows us to reveal that this transition is a parametric resonance between the frequencies of interface modes and the forcing. Numerical simulations of magnetic systems, extended Josephson junctions, and our simplified model show quite good agreement. PMID- 29448358 TI - Autonomous quantum Maxwell's demon based on two exchange-coupled quantum dots. AB - I study an autonomous quantum Maxwell's demon based on two exchange-coupled quantum dots attached to the spin-polarized leads. The principle of operation of the demon is based on the coherent oscillations between the spin states of the system which act as a quantum iSWAP gate. Due to the operation of the iSWAP gate, one of the dots acts as a feedback controller which blocks the transport with the bias in the other dot, thus inducing the electron pumping against the bias; this leads to the locally negative entropy production. Operation of the demon is associated with the information transfer between the dots, which is studied quantitatively by mapping the analyzed setup onto the thermodynamically equivalent auxiliary system. The calculated entropy production in a single subsystem and information flow between the subsystems are shown to obey a local form of the second law of thermodynamics, similar to the one previously derived for classical bipartite systems. PMID- 29448359 TI - Simple analysis of scattering data with the Ornstein-Zernike equation. AB - In this paper we propose and explore a method of analysis of the scattering experimental data for uniform liquidlike systems. In our pragmatic approach we are not trying to introduce by hands an artificial small parameter to work out a perturbation theory with respect to the known results, e.g., for hard spheres or sticky hard spheres (all the more that in the agreement with the notorious Landau statement, there is no physical small parameter for liquids). Instead of it being guided by the experimental data we are solving the Ornstein-Zernike equation with a trial (variational) form of the interparticle interaction potential. To find all needed correlation functions this variational input is iterated numerically to satisfy the Ornstein-Zernike equation supplemented by a closure relation. Our method is developed for spherically symmetric scattering objects, and our numeric code is written for such a case. However, it can be extended (at the expense of more involved computations and a larger amount of required experimental input information) for nonspherical particles. What is important for our approach is that it is sufficient to know experimental data in a relatively narrow range of the scattering wave vectors (q) to compute the static structure factor in a much broader range of q. We illustrate by a few model and real experimental examples of the x-ray and neutron scattering data how the approach works. PMID- 29448360 TI - Enhancement of large fluctuations to extinction in adaptive networks. AB - During an epidemic, individual nodes in a network may adapt their connections to reduce the chance of infection. A common form of adaption is avoidance rewiring, where a noninfected node breaks a connection to an infected neighbor and forms a new connection to another noninfected node. Here we explore the effects of such adaptivity on stochastic fluctuations in the susceptible-infected-susceptible model, focusing on the largest fluctuations that result in extinction of infection. Using techniques from large-deviation theory, combined with a measurement of heterogeneity in the susceptible degree distribution at the endemic state, we are able to predict and analyze large fluctuations and extinction in adaptive networks. We find that in the limit of small rewiring there is a sharp exponential reduction in mean extinction times compared to the case of zero adaption. Furthermore, we find an exponential enhancement in the probability of large fluctuations with increased rewiring rate, even when holding the average number of infected nodes constant. PMID- 29448361 TI - Bridges in complex networks. AB - A bridge in a graph is an edge whose removal disconnects the graph and increases the number of connected components. We calculate the fraction of bridges in a wide range of real-world networks and their randomized counterparts. We find that real networks typically have more bridges than their completely randomized counterparts, but they have a fraction of bridges that is very similar to their degree-preserving randomizations. We define an edge centrality measure, called bridgeness, to quantify the importance of a bridge in damaging a network. We find that certain real networks have a very large average and variance of bridgeness compared to their degree-preserving randomizations and other real networks. Finally, we offer an analytical framework to calculate the bridge fraction and the average and variance of bridgeness for uncorrelated random networks with arbitrary degree distributions. PMID- 29448362 TI - Dynamic phase transition of the Blume-Capel model in an oscillating magnetic field. AB - We employ numerical simulations and finite-size scaling techniques to investigate the properties of the dynamic phase transition that is encountered in the Blume Capel model subjected to a periodically oscillating magnetic field. We mainly focus on the study of the two-dimensional system for various values of the crystal-field coupling in the second-order transition regime. Our results indicate that the present nonequilibrium phase transition belongs to the universality class of the equilibrium Ising model and allow us to construct a dynamic phase diagram, in analogy with the equilibrium case, at least for the range of parameters considered. Finally, we present some complementary results for the three-dimensional model, where again the obtained estimates for the critical exponents fall into the universality class of the corresponding three dimensional equilibrium Ising ferromagnet. PMID- 29448363 TI - Finite-element lattice Boltzmann simulations of contact line dynamics. AB - The lattice Boltzmann method has become one of the standard techniques for simulating a wide range of fluid flows. However, the intrinsic coupling of momentum and space discretization restricts the traditional lattice Boltzmann method to regular lattices. Alternative off-lattice Boltzmann schemes exist for both single- and multiphase flows that decouple the velocity discretization from the underlying spatial grid. The current study extends the applicability of these off-lattice methods by introducing a finite element formulation that enables simulating contact line dynamics for partially wetting fluids. This work exemplifies the implementation of the scheme and furthermore presents benchmark experiments that show the scheme reduces spurious currents at the liquid-vapor interface by at least two orders of magnitude compared to a nodal implementation and allows for predicting the equilibrium states accurately in the range of moderate contact angles. PMID- 29448364 TI - Snap-buckling in asymmetrically constrained elastic strips. AB - When a flat elastic strip is compressed along its axis, it is bent in one of two possible directions via spontaneous symmetry breaking, forming a cylindrical arc. This is a phenomenon well known as Euler buckling. When this cylindrical section is pushed in the other direction, the bending direction can suddenly reverse. This instability is called "snap-through buckling" and is one of the elementary shape transitions in a prestressed thin structure. Combining experiments and theory, we study snap-buckling of an elastic strip with one end hinged and the other end clamped. These asymmetric boundary constraints break the intrinsic symmetry of the strip, generating mechanical behaviors, including largely hysteretic but reproducible force responses and switchlike discontinuous shape changes. We establish the set of exact analytical solutions to fully explain all our major experimental and numerical findings. Asymmetric boundary conditions arise naturally in diverse situations when a thin object is in contact with a solid surface at one end. The introduction of asymmetry through boundary conditions yields new insight into complex and programmable functionalities in material and industrial design. PMID- 29448365 TI - Improved belief propagation algorithm finds many Bethe states in the random-field Ising model on random graphs. AB - We first present an empirical study of the Belief Propagation (BP) algorithm, when run on the random field Ising model defined on random regular graphs in the zero temperature limit. We introduce the notion of extremal solutions for the BP equations, and we use them to fix a fraction of spins in their ground state configuration. At the phase transition point the fraction of unconstrained spins percolates and their number diverges with the system size. This in turn makes the associated optimization problem highly non trivial in the critical region. Using the bounds on the BP messages provided by the extremal solutions we design a new and very easy to implement BP scheme which is able to output a large number of stable fixed points. On one hand this new algorithm is able to provide the minimum energy configuration with high probability in a competitive time. On the other hand we found that the number of fixed points of the BP algorithm grows with the system size in the critical region. This unexpected feature poses new relevant questions about the physics of this class of models. PMID- 29448366 TI - Growth-mediated autochemotactic pattern formation in self-propelling bacteria. AB - Bacteria, while developing a multicellular colony or biofilm, can undergo pattern formation by diverse intricate mechanisms. One such route is directional movement or chemotaxis toward or away from self-secreted or externally employed chemicals. In some bacteria, the self-produced signaling chemicals or autoinducers themselves act as chemoattractants or chemorepellents and thereby regulate the directional movements of the cells in the colony. In addition, bacteria follow a certain growth kinetics which is integrated in the process of colony development. Here, we study the interplay of bacterial growth dynamics, cell motility, and autochemotactic motion with respect to the self-secreted diffusive signaling chemicals in spatial pattern formation. Using a continuum model of motile bacteria, we show growth can act as a crucial tuning parameter in determining the spatiotemporal dynamics of a colony. In action of growth dynamics, while chemoattraction toward autoinducers creates arrested phase separation, pattern transitions and suppression can occur for a fixed chemorepulsive strength. PMID- 29448367 TI - First-passage time for superstatistical Fokker-Planck models. AB - The first-passage-time (FPT) problem is studied for superstatistical models assuming that the mesoscopic system dynamics is described by a Fokker-Planck equation. We show that all moments of the random intensive parameter associated to the superstatistical approach can be put in one-to-one correspondence with the moments of the FPT. For systems subjected to an additional uncorrelated external force, the same statistical information is obtained from the dependence of the FPT moments on the external force. These results provide an alternative technique for checking the validity of superstatistical models. As an example, we characterize the mean FPT for a forced Brownian particle. PMID- 29448368 TI - Disentangling the role of athermal walls on the Knudsen paradox in molecular and granular gases. AB - The nature of particle-wall interactions is shown to have a profound impact on the well-known "Knudsen paradox" [or the "Knudsen minimum" effect, which refers to the decrease of the mass-flow rate of a gas with increasing Knudsen number Kn, reaching a minimum at Kn~O(1) and increasing logarithmically with Kn as Kn >infinity] in the acceleration-driven Poiseuille flow of rarefied gases. The nonmonotonic variation of the flow rate with Kn occurs even in a granular or dissipative gas in contact with thermal walls. The latter result is in contradiction with recent work [Alam et al., J. Fluid Mech. 782, 99 (2015)JFLSA70022-112010.1017/jfm.2015.523] that revealed the absence of the Knudsen minimum in granular Poiseuille flow for which the flow rate was found to decrease at large values of Kn. The above conundrum is resolved by distinguishing between "thermal" and "athermal" walls, and it is shown that, for both molecular and granular gases, the momentum transfer to athermal walls is much different than that to thermal walls which is directly responsible for the anomalous flow rate variation with Kn in the rarefied regime. In the continuum limit of Kn->0, the athermal walls are shown to be closely related to "no-flux" ("adiabatic") walls for which the Knudsen minimum does not exist either. A possible characterization of athermal walls in terms of (1) an effective specularity coefficient for the slip velocity and (2) a flux-type boundary condition for granular temperature is suggested based on simulation results. PMID- 29448369 TI - Three-dimensional instabilities for the flow around a heaving foil. AB - This paper investigates the three-dimensional instabilities of the flow past a periodically heaving airfoil. By comparison with a pitching foil [Deng et al., Phys. Rev. E 92, 063013 (2015)PLEEE81539-375510.1103/PhysRevE.92.063013], here we present distinctive characteristics for the heaving foil, particulary regarding its Floquet modes. By increasing the frequency (Sr), or equivalently decreasing the amplitude (A_{D}) along the marginal stability curve in the (Sr,A_{D}) phase space, the critical Floquet mode emerges sequentially as A, quasiperiodic (QP), and B. It is interesting to note that both modes A and B are synchronous with the base flow, in contrast to the quasiperiodic mode QP. To further investigate the instability across the marginal curve, we fix the frequency at Sr=0.187, of which the critical Floquet mode is located in the synchronous regime, while varying A_{D} around the critical point. We find that the dominant mode switches from mode A to mode B, while mode QP never becomes critical as we increase A_{D}. We note that mode S, a subharmonic mode, can also be unstable, which, however, is not physically realizable, because the magnitude of its Floquet multiplier is always smaller than that of mode B. We have also studied the influence of various Reynolds numbers at the same critical point on the marginal stability curve, with the results resembling that by varying the amplitude A_{D}. PMID- 29448370 TI - Rigorous proof for the nonlocal correlation function in the transverse Ising model with ring frustration. AB - An unusual correlation function was conjectured by Campostrini et al. [Phys. Rev. E 91, 042123 (2015)PLEEE81539-375510.1103/PhysRevE.91.042123] for the ground state of a transverse Ising chain with geometrical frustration. Later, we provided a rigorous proof for it and demonstrated its nonlocal nature based on an evaluation of a Toeplitz determinant in the thermodynamic limit [J. Stat. Mech. (2016) 11310210.1088/1742-5468/2016/11/113102]. In this paper, we further prove that all the low excited energy states forming the gapless kink phase share the same asymptotic correlation function with the ground state. As a consequence, the thermal correlation function almost remains constant at low temperatures if one assumes a canonical ensemble. PMID- 29448371 TI - Decoherence approach to energy transfer and work done by slowly driven systems. AB - A main problem, which is met when computing the energy transfer of or work done by a quantum system, comes from the fact that the system may lie in states with coherence in its energy eigenstates. As is well known, when the so-called environment-induced decoherence has happened with respect to a preferred basis given by the energy basis, no coherence exists among the energy basis and the energy change of the system can be computed in a definite way. I argue that one may make use of this property, in the search for an appropriate definition of quantum work for a total system that does not include any measuring apparatus. To show how this idea may work, in this paper, I study decoherence properties of a generic slowly driven system, which is weakly coupled to a huge environment whose main body is a complex quantum system. It is shown that decoherence may generically happen for such a system. PMID- 29448372 TI - Quantum theory for the dynamic structure factor in correlated two-component systems in nonequilibrium: Application to x-ray scattering. AB - We present a quantum theory for the dynamic structure factors in nonequilibrium, correlated, two-component systems such as plasmas or warm dense matter. The polarization function, which is needed as the input for the calculation of the structure factors, is calculated in nonequilibrium based on a perturbation expansion in the interaction strength. To make our theory applicable for x-ray scattering, a generalized Chihara decomposition for the total electron structure factor in nonequilibrium is derived. Examples are given and the influence of correlations and exchange on the structure and the x-ray-scattering spectrum are discussed for a model nonequilibrium distribution, as often encountered during laser heating of materials, as well as for two-temperature systems. PMID- 29448373 TI - Optimal performance of generalized heat engines with finite-size baths of arbitrary multiple conserved quantities beyond independent-and-identical distribution scaling. AB - In quantum thermodynamics, effects of finiteness of the baths have been less considered. In particular, there is no general theory which focuses on finiteness of the baths of multiple conserved quantities. Then, we investigate how the optimal performance of generalized heat engines with multiple conserved quantities alters in response to the size of the baths. In the context of general theories of quantum thermodynamics, the size of the baths has been given in terms of the number of identical copies of a system, which does not cover even such a natural scaling as the volume. In consideration of the asymptotic extensivity, we deal with a generic scaling of the baths to naturally include the volume scaling. Based on it, we derive a bound for the performance of generalized heat engines reflecting finite-size effects of the baths, which we call fine-grained generalized Carnot bound. We also construct a protocol to achieve the optimal performance of the engine given by this bound. Finally, applying the obtained general theory, we deal with simple examples of generalized heat engines. As for an example of non-independent-and-identical-distribution scaling and multiple conserved quantities, we investigate a heat engine with two baths composed of an ideal gas exchanging particles, where the volume scaling is applied. The result implies that the mass of the particle explicitly affects the performance of this engine with finite-size baths. PMID- 29448374 TI - Characterizing real-space topology in Rice-Mele model by thermodynamics. AB - The thermodynamic quantities which are related to energy-level statistics are used to characterize the real-space topology of the Rice-Mele model. Through studying the energy spectrum of the model under different boundary conditions, we found that the non-normalizable wave function for the infinite domain is reduced to the edge state adhered to the boundary. For the finite domain with symmetric boundary condition, the critical point for the topological phase transition is equal to the inverse of the domain length. In contrast, the critical point is zero for the semi-infinite domain. Additionally, the symmetry of the energy spectrum is found to be sensitive to the boundary conditions of the Rice-Mele model, and the emergence of the edge states as well as the topological phase transition can be reflected in the thermodynamic properties. A potentially practical scheme is proposed for simulating the Rice-Mele model and detecting the relevant thermodynamic quantities in the context of Bose-Einstein condensate. PMID- 29448375 TI - Natural extension of fast-slow decomposition for dynamical systems. AB - Modeling and parameter estimation to capture the dynamics of physical systems are often challenging because many parameters can range over orders of magnitude and are difficult to measure experimentally. Moreover, selecting a suitable model complexity requires a sufficient understanding of the model's potential use, such as highlighting essential mechanisms underlying qualitative behavior or precisely quantifying realistic dynamics. We present an approach that can guide model development and tuning to achieve desired qualitative and quantitative solution properties. It relies on the presence of disparate time scales and employs techniques of separating the dynamics of fast and slow variables, which are well known in the analysis of qualitative solution features. We build on these methods to show how it is also possible to obtain quantitative solution features by imposing designed dynamics for the slow variables in the form of specified two dimensional paths in a bifurcation-parameter landscape. PMID- 29448376 TI - Matrix product algorithm for stochastic dynamics on networks applied to nonequilibrium Glauber dynamics. AB - We introduce and apply an efficient method for the precise simulation of stochastic dynamical processes on locally treelike graphs. Networks with cycles are treated in the framework of the cavity method. Such models correspond, for example, to spin-glass systems, Boolean networks, neural networks, or other technological, biological, and social networks. Building upon ideas from quantum many-body theory, our approach is based on a matrix product approximation of the so-called edge messages-conditional probabilities of vertex variable trajectories. Computation costs and accuracy can be tuned by controlling the matrix dimensions of the matrix product edge messages (MPEM) in truncations. In contrast to Monte Carlo simulations, the algorithm has a better error scaling and works for both single instances as well as the thermodynamic limit. We employ it to examine prototypical nonequilibrium Glauber dynamics in the kinetic Ising model. Because of the absence of cancellation effects, observables with small expectation values can be evaluated accurately, allowing for the study of decay processes and temporal correlations.

AB - The shape of liquid crystalline elastomers (LCEs) with spatial variation in the director orientation can be transformed by exposure to a stimulus. Here, informed by previously reported analytical treatments, we prepare complex spiral patterns imprinted into LCEs and quantify the resulting shape transformation. Quantification of the stimuli-induced shapes reveals good agreement between predicted and experimentally observed curvatures. We conclude this communication by reporting a design strategy to allow LCE films to be anchored at their external boundaries onto rigid substrates without incurring internal, mechanical mismatch stresses upon actuation, a critical advance to the realization of shape transformation of LCEs in practical device applications. PMID- 29448378 TI - Memory effects for a stochastic fractional oscillator in a magnetic field. AB - The problem of random motion of harmonically trapped charged particles in a constant external magnetic field is studied. A generalized three-dimensional Langevin equation with a power-law memory kernel is used to model the interaction of Brownian particles with the complex structure of viscoelastic media (e.g., dusty plasmas). The influence of a fluctuating environment is modeled by an additive fractional Gaussian noise. In the long-time limit the exact expressions of the first-order and second-order moments of the fluctuating position for the Brownian particle subjected to an external periodic force in the plane perpendicular to the magnetic field have been calculated. Also, the particle's angular momentum is found. It is shown that an interplay of external periodic forcing, memory, and colored noise can generate a variety of cooperation effects, such as memory-induced sign reversals of the angular momentum, multiresonance versus Larmor frequency, and memory-induced particle confinement in the absence of an external trapping field. Particularly in the case without external trapping, if the memory exponent is lower than a critical value, we find a resonancelike behavior of the anisotropy in the particle position distribution versus the driving frequency, implying that it can be efficiently excited by an oscillating electric field. Similarities and differences between the behaviors of the models with internal and external noises are also discussed. PMID- 29448379 TI - Time evolution of intermittency in the passive slider problem. AB - How does a steady state with strong intermittency develop in time from an initial state which is statistically random? For passive sliders driven by various fluctuating surfaces, we show that the approach involves an indefinitely growing length scale which governs scaling properties. A simple model of sticky sliders suggests scaling forms for the time-dependent flatness and hyperflatness, both measures of intermittency and these are confirmed numerically for passive sliders driven by a Kardar-Parisi-Zhang surface. Aging properties are studied via a two time flatness. We predict and verify numerically that the time-dependent flatness is, remarkably, a nonmonotonic function of time with different scaling forms at short and long times. The scaling description remains valid when clustering is more diffuse as for passive sliders evolving through Edwards-Wilkinson driving or under antiadvection, although exponents and scaling functions differ substantially. PMID- 29448380 TI - Theoretical model of chirality-induced helical self-propulsion. AB - We recently reported the experimental realization of a chiral artificial microswimmer exhibiting helical self-propulsion [T. Yamamoto and M. Sano, Soft Matter 13, 3328 (2017)1744-683X10.1039/C7SM00337D]. In the experiment, cholesteric liquid crystal (CLC) droplets dispersed in surfactant solutions swam spontaneously, driven by the Marangoni flow, in helical paths whose handedness is determined by the chirality of the component molecules of CLC. To study the mechanism of the emergence of the helical self-propelled motion, we propose a phenomenological model of the self-propelled helical motion of the CLC droplets. Our model is constructed by symmetry argument in chiral systems, and it describes the dynamics of CLC droplets with coupled time-evolution equations in terms of a velocity, an angular velocity, and a tensor variable representing the symmetry of the helical director field of the droplet. We found that helical motions as well as other chiral motions appear in our model. By investigating bifurcation behaviors between each chiral motion, we found that the chiral coupling terms between the velocity and the angular velocity, the structural anisotropy of the CLC droplet, and the nonlinearity of model equations play a crucial role in the emergence of the helical motion of the CLC droplet.

AB - As an important intracellular signal, Ca^{2+} ions control diverse cellular functions. In this paper, we discuss the Ca^{2+} signaling with a two-dimensional model in which the inositol 1,4,5-trisphosphate (IP_{3}) receptor channels are distributed in clusters on the endoplasmic reticulum membrane. The wave failure at large Ca^{2+} diffusion coupling is discussed in detail in the model. We show that with varying model parameters the wave failure is a robust behavior with either deterministic or stochastic channel dynamics. We suggest that the wave failure should be a general behavior in inhomogeneous diffusing systems with clustered excitable regions and may occur in biological Ca^{2+} signaling systems.

AB - We study the relaxation dynamics of fully clustered networks (maximal number of triangles) to an unclustered state under two different edge dynamics-the double edge swap, corresponding to degree-preserving randomization of the configuration model, and single edge replacement, corresponding to full randomization of the Erdos-Renyi random graph. We derive expressions for the time evolution of the degree distribution, edge multiplicity distribution and clustering coefficient. We show that under both dynamics networks undergo a continuous phase transition in which a giant connected component is formed. We calculate the position of the phase transition analytically using the Erdos-Renyi phenomenology. PMID- 29448383 TI - Microscopic processes controlling the Herschel-Bulkley exponent. AB - The flow curve of various yield stress materials is singular as the strain rate vanishes and can be characterized by the so-called Herschel-Bulkley exponent n=1/beta. A mean-field approximation due to Hebraud and Lequeux (HL) assumes mechanical noise to be Gaussian and leads to beta=2 in rather good agreement with observations. Here we prove that the improved mean-field model where the mechanical noise has fat tails instead leads to beta=1 with logarithmic correction. This result supports that HL is not a suitable explanation for the value of beta, which is instead significantly affected by finite-dimensional effects. From considerations on elastoplastic models and on the limitation of speed at which avalanches of plasticity can propagate, we argue that beta=1+1/(d d_{f}), where d_{f} is the fractal dimension of avalanches and d the spatial dimension. Measurements of d_{f} then supports that beta~2.1 and beta~1.7 in two and three dimensions, respectively. We discuss theoretical arguments leading to approximations of beta in finite dimensions.

AB - Thermal convection is numerically computed in three-dimensional (3D) fluid saturated isotropically fractured porous media. Fractures are randomly inserted as two-dimensional (2D) convex polygons. Flow is governed by Darcy's 2D and 3D laws in the fractures and in the porous medium, respectively; exchanges take place between these two structures. Results for unfractured porous media are in agreement with known theoretical predictions. The influence of parameters such as the fracture aperture (or fracture transmissivity) and the fracture density on the heat released by the whole system is studied for Rayleigh numbers up to 150 in cubic boxes with closed-top conditions. Then, fractured media are compared to homogeneous porous media with the same macroscopic properties. Three major results could be derived from this study. The behavior of the system, in terms of heat release, is determined as a function of fracture density and fracture transmissivity. First, the increase in the output flux with fracture density is linear over the range of fracture density tested. Second, the increase in output flux as a function of fracture transmissivity shows the importance of percolation. Third, results show that the effective approach is not always valid, and that the mismatch between the full calculations and the effective medium approach depends on the fracture density in a crucial way.

AB - We probe the effects of particle shape on the global and local behavior of a two dimensional granular pillar, acting as a proxy for a disordered solid, under uniaxial compression. This geometry allows for direct measurement of global material response, as well as tracking of all individual particle trajectories. In general, drawing connections between local structure and local dynamics can be challenging in amorphous materials due to lower precision of atomic positions, so this study aims to elucidate such connections. We vary local interactions by using three different particle shapes: discrete circular grains (monomers), pairs of grains bonded together (dimers), and groups of three bonded in a triangle (trimers). We find that dimers substantially strengthen the pillar and the degree of this effect is determined by orientational order in the initial condition. In addition, while the three particle shapes form void regions at distinct rates, we find that anisotropies in the local amorphous structure remain robust through the definition of a metric that quantifies packing anisotropy. Finally, we highlight connections between local deformation rates and local structure. PMID- 29448386 TI - Theoretical analysis of the distribution of isolated particles in totally asymmetric exclusion processes: Application to mRNA translation rate estimation. AB - The Totally Asymmetric Exclusion Process (TASEP) is a classical stochastic model for describing the transport of interacting particles, such as ribosomes moving along the messenger ribonucleic acid (mRNA) during translation. Although this model has been widely studied in the past, the extent of collision between particles and the average distance between a particle to its nearest neighbor have not been quantified explicitly. We provide here a theoretical analysis of such quantities via the distribution of isolated particles. In the classical form of the model in which each particle occupies only a single site, we obtain an exact analytic solution using the matrix ansatz. We then employ a refined mean field approach to extend the analysis to a generalized TASEP with particles of an arbitrary size. Our theoretical study has direct applications in mRNA translation and the interpretation of experimental ribosome profiling data. In particular, our analysis of data from Saccharomyces cerevisiae suggests a potential bias against the detection of nearby ribosomes with a gap distance of less than approximately three codons, which leads to some ambiguity in estimating the initiation rate and protein production flux for a substantial fraction of genes. Despite such ambiguity, however, we demonstrate theoretically that the interference rate associated with collisions can be robustly estimated and show that approximately 1% of the translating ribosomes get obstructed. PMID- 29448387 TI - Pressure evolution and deformation of confined granular media during pneumatic fracturing. AB - By means of digital image correlation, we experimentally characterize the deformation of a dry granular medium confined inside a Hele-Shaw cell due to air injection at a constant overpressure high enough to deform it (from 50 to 250 kPa). Air injection at these overpressures leads to the formation of so-called pneumatic fractures, i.e., channels empty of beads, and we discuss the typical deformations of the medium surrounding these structures. In addition we simulate the diffusion of the fluid overpressure into the medium, comparing it with the Laplacian solution over time and relating pressure gradients with corresponding granular displacements. In the compacting medium we show that the diffusing pressure field becomes similar to the Laplace solution on the order of a characteristic time given by the properties of the pore fluid, the granular medium, and the system size. However, before the diffusing pressure approaches the Laplace solution on the system scale, we find that it resembles the Laplacian field near the channels, with the highest pressure gradients on the most advanced channel tips and a screened pressure gradient behind them. We show that the granular displacements more or less always move in the direction against the local pressure gradients, and when comparing granular velocities with pressure gradients in the zone ahead of channels, we observe a Bingham type of rheology for the granular paste (the mix of air and beads), with an effective viscosity MU_{B} and displacement thresholds ?[over ?]P_{c} evolving during mobilization and compaction of the medium. Such a rheology, with disorder in the displacement thresholds, could be responsible for placing the pattern growth at moderate injection pressures in a universality class like the dielectric breakdown model with eta=2, where fractal dimensions are found between 1.5 and 1.6 for the patterns. PMID- 29448388 TI - Patterning of a cohesionless granular layer under pure shear. AB - The response of a thin layer of granular material to an external pure shear imposed at its base is investigated. The experiments show that, even for noncohesive materials, the resulting deformation of the material is inhomogeneous. Indeed, a novel smooth pattern, consisting of a periodic modulation of the shear deformation of the free surface, is revealed by an image correlation technique. These observations are in contrast with the previous observation of the fracture pattern in cohesive granular materials subjected to stretching. For cohesive materials, the instability is due to the weakening of the material which results from the rupture of capillary bridges that bond the grains to one another. For noncohesive materials, the rupture of the capillary bridges cannot be invoked anymore. We show that the instability results from the decrease of friction on shearing.

PMID- 29448389 TI - Development of an efficient gas kinetic scheme for simulation of two-dimensional incompressible thermal flows. AB - In this work, an efficient gas kinetic scheme is presented for simulation of two dimensional incompressible thermal flows. In the scheme, the macroscopic governing equations for mass, momentum, and energy conservation are discretized by the finite volume method and the numerical fluxes at the cell interface are reconstructed by the local solution of the Boltzmann equation. To compute these fluxes, two distribution functions are involved. One is the circular function, which is used to calculate the numerical fluxes of mass and momentum equations. Due to the incompressible limit, the circle at the cell interface can be approximately considered to be symmetric so that the expressions for the conservative variables and numerical fluxes at the cell interface can be given explicitly and concisely. Another one is the D2Q4 model, which is utilized to compute the numerical flux of the energy equation. By following the process for derivation of numerical fluxes of mass and momentum equations, the numerical flux of the energy equation can also be given explicitly. The accuracy, efficiency, and stability of the present scheme are validated by simulating several thermal flow problems. Numerical results showed that the present scheme can provide accurate numerical results for incompressible thermal flows at a wide range of Rayleigh numbers with less computational cost than that needed by the thermal lattice Boltzmann flux solver (TLBFS), which has been proven to be more efficient than the thermal lattice Boltzmann method (TLBM). PMID- 29448390 TI - Kullback-Leibler divergence measure of intermittency: Application to turbulence. AB - For generic systems exhibiting power law behaviors, and hence multiscale dependencies, we propose a simple tool to analyze multifractality and intermittency, after noticing that these concepts are directly related to the deformation of a probability density function from Gaussian at large scales to non-Gaussian at smaller scales. Our framework is based on information theory and uses Shannon entropy and Kullback-Leibler divergence. We provide an extensive application to three-dimensional fully developed turbulence, seen here as a paradigmatic complex system where intermittency was historically defined and the concepts of scale invariance and multifractality were extensively studied and benchmarked. We compute our quantity on experimental Eulerian velocity measurements, as well as on synthetic processes and phenomenological models of fluid turbulence. Our approach is very general and does not require any underlying model of the system, although it can probe the relevance of such a model. PMID- 29448391 TI - Relationship between the mechanisms of gamma rhythm generation and the magnitude of the macroscopic phase response function in a population of excitatory and inhibitory modified quadratic integrate-and-fire neurons. AB - Gamma oscillations are thought to play an important role in brain function. Interneuron gamma (ING) and pyramidal interneuron gamma (PING) mechanisms have been proposed as generation mechanisms for these oscillations. However, the relation between the generation mechanisms and the dynamical properties of the gamma oscillation are still unclear. Among the dynamical properties of the gamma oscillation, the phase response function (PRF) is important because it encodes the response of the oscillation to inputs. Recently, the PRF for an inhibitory population of modified theta neurons that generate an ING rhythm was computed by the adjoint method applied to the associated Fokker-Planck equation (FPE) for the model. The modified theta model incorporates conductance-based synapses as well as the voltage and current dynamics. Here, we extended this previous work by creating an excitatory-inhibitory (E-I) network using the modified theta model and described the population dynamics with the corresponding FPE. We conducted a bifurcation analysis of the FPE to find parameter regions which generate gamma oscillations. In order to label the oscillatory parameter regions by their generation mechanisms, we defined ING- and PING-type gamma oscillation in a mathematically plausible way based on the driver of the inhibitory population. We labeled the oscillatory parameter regions by these generation mechanisms and derived PRFs via the adjoint method on the FPE in order to investigate the differences in the responses of each type of oscillation to inputs. PRFs for PING and ING mechanisms are derived and compared. We found the amplitude of the PRF for the excitatory population is larger in the PING case than in the ING case. Finally, the E-I population of the modified theta neuron enabled us to analyze the PRFs of PING-type gamma oscillation and the entrainment ability of E and I populations. We found a parameter region in which PRFs of E and I are both purely positive in the case of PING oscillations. The different entrainment abilities of E and I stimulation as governed by the respective PRFs was compared to direct simulations of finite populations of model neurons. We find that it is easier to entrain the gamma rhythm by stimulating the inhibitory population than by stimulating the excitatory population as has been found experimentally.

AB - The effect of strong confinement on the positional and orientational ordering is examined in a system of hard rectangular rods with length L and diameter D (L>D) using the Parsons-Lee modification of the second virial density-functional theory. The rods are nonmesogenic (L/D<3) and confined between two parallel hard walls, where the width of the pore (H) is chosen in such a way that both planar (particle's long axis parallel to the walls) and homeotropic (particle's long axis perpendicular to the walls) orderings are possible and a maximum of two layers is allowed to form in the pore. In the extreme confinement limit of H<=2D, where only one-layer structures appear, we observe a structural transition from a planar to a homeotropic fluid layer with increasing density, which becomes sharper as L->H. In wider pores (2DA_{c}, the phase transition is of mixed order: the surface order parameter is discontinuous; at the same time the temporal correlation length diverges algebraically as the critical point is approached, but with different exponents on the two sides of the transition. The mixed-order transition regime is analogous to that observed recently at a multiple junction and can be explained by the same type of scaling theory.

AB - An artificial cilium using ac electro-osmosis (ACEO) is attractive because of its large potentiality for innovative microfluidic applications. However, the ACEO cilium has not been probed experimentally and has a shortcoming that the working frequency range is very narrow. Thus, we here propose an ACEO elastic actuator having a skew structure that broadens a working frequency range and experimentally demonstrate that the elastic actuator in water can be driven with a high-speed (~10 Hz) and a wide frequency range (~0.1 to ~10 kHz). Moreover, we propose a simple self-consistent model that explains the broadband characteristic due to the skew structure with other characteristics. By comparing the theoretical results with the experimental results, we find that they agree fairly well. We believe that our ACEO elastic actuator will play an important role in microfluidics in the future. PMID- 29448449 TI - Unsupervised machine learning account of magnetic transitions in the Hubbard model. AB - We employ several unsupervised machine learning techniques, including autoencoders, random trees embedding, and t-distributed stochastic neighboring ensemble (t-SNE), to reduce the dimensionality of, and therefore classify, raw (auxiliary) spin configurations generated, through Monte Carlo simulations of small clusters, for the Ising and Fermi-Hubbard models at finite temperatures. Results from a convolutional autoencoder for the three-dimensional Ising model can be shown to produce the magnetization and the susceptibility as a function of temperature with a high degree of accuracy. Quantum fluctuations distort this picture and prevent us from making such connections between the output of the autoencoder and physical observables for the Hubbard model. However, we are able to define an indicator based on the output of the t-SNE algorithm that shows a near perfect agreement with the antiferromagnetic structure factor of the model in two and three spatial dimensions in the weak-coupling regime. t-SNE also predicts a transition to the canted antiferromagnetic phase for the three dimensional model when a strong magnetic field is present. We show that these techniques cannot be expected to work away from half filling when the "sign problem" in quantum Monte Carlo simulations is present. PMID- 29448450 TI - Nonlinear excitation of the ablative Rayleigh-Taylor instability for all wave numbers. AB - Small-scale perturbations in the ablative Rayleigh-Taylor instability (ARTI) are often neglected because they are linearly stable when their wavelength is shorter than a linear cutoff. Using two-dimensional (2D) and three-dimensional (3D) numerical simulations, it is shown that linearly stable modes of any wavelength can be destabilized. This instability regime requires finite amplitude initial perturbations and linearly stable ARTI modes to be more easily destabilized in 3D than in 2D. It is shown that for conditions found in laser fusion targets, short wavelength ARTI modes are more efficient at driving mixing of ablated material throughout the target since the nonlinear bubble density increases with the wave number and small-scale bubbles carry a larger mass flux of mixed material.

AB - How systems transit between different stable states under external perturbation is an important practical issue. We discuss here how a recently developed energy optimization method for identifying the minimal disturbance necessary to reach the basin boundary of a stable state is connected to the instanton trajectory from large deviation theory of noisy systems. In the context of the one dimensional Swift-Hohenberg equation, which has multiple stable equilibria, we first show how the energy optimization method can be straightforwardly used to identify minimal disturbances-minimal seeds-for transition to specific attractors from the ground state. Then, after generalizing the technique to consider multiple, equally spaced-in-time perturbations, it is shown that the instanton trajectory is indeed the solution of the energy optimization method in the limit of infinitely many perturbations provided a specific norm is used to measure the set of discrete perturbations. Importantly, we find that the key features of the instanton can be captured by a low number of discrete perturbations (typically one perturbation per basin of attraction crossed). This suggests a promising new diagnostic for systems for which it may be impractical to calculate the instanton. PMID- 29448453 TI - Electroneutral models for dynamic Poisson-Nernst-Planck systems. AB - The Poisson-Nernst-Planck (PNP) system is a standard model for describing ion transport. In many applications, e.g., ions in biological tissues, the presence of thin boundary layers poses both modeling and computational challenges. In this paper, we derive simplified electroneutral (EN) models where the thin boundary layers are replaced by effective boundary conditions. There are two major advantages of EN models. First, it is much cheaper to solve them numerically. Second, EN models are easier to deal with compared to the original PNP system; therefore, it would also be easier to derive macroscopic models for cellular structures using EN models. Even though the approach used here is applicable to higher-dimensional cases, this paper mainly focuses on the one-dimensional system, including the general multi-ion case. Using systematic asymptotic analysis, we derive a variety of effective boundary conditions directly applicable to the EN system for the bulk region. This EN system can be solved directly and efficiently without computing the solution in the boundary layer. The derivation is based on matched asymptotics, and the key idea is to bring back higher-order contributions into the effective boundary conditions. For Dirichlet boundary conditions, the higher-order terms can be neglected and the classical results (continuity of electrochemical potential) are recovered. For flux boundary conditions, higher-order terms account for the accumulation of ions in boundary layer and neglecting them leads to physically incorrect solutions. To validate the EN model, numerical computations are carried out for several examples. Our results show that solving the EN model is much more efficient than the original PNP system. Implemented with the Hodgkin-Huxley model, the computational time for solving the EN model is significantly reduced without sacrificing the accuracy of the solution due to the fact that it allows for relatively large mesh and time-step sizes. PMID- 29448454 TI - Uniaxial and biaxial structures in the elastic Maier-Saupe model. AB - We perform statistical mechanics calculations to analyze the global phase diagram of a fully connected version of a Maier-Saupe-Zwanzig lattice model with the inclusion of couplings to an elastic strain field. We point out the presence of uniaxial and biaxial nematic structures, depending on temperature T and on the applied stress sigma. Under uniaxial extensive tension, applied stress favors uniaxial orientation, and we obtain a first-order boundary along which there is a coexistence of two uniaxial paranematic phases, and which ends at a simple critical point. Under uniaxial compressive tension, stress favors biaxial orientation; for small values of the coupling parameters, the first-order boundary ends at a tricritical point, beyond which there is a continuous transition between a paranematic and a biaxially ordered structure. For some representative choices of the model parameters, we obtain a number of analytic results, including the location of critical and tricritical points and the line of stability of the biaxial phase. PMID- 29448455 TI - Triviality of the ground-state metastate in long-range Ising spin glasses in one dimension. AB - We consider the one-dimensional model of a spin glass with independent Gaussian distributed random interactions, which have mean zero and variance 1/|i j|^{2sigma}, between the spins at sites i and j for all i?j. It is known that, for sigma>1, there is no phase transition at any nonzero temperature in this model. We prove rigorously that, for sigma>3/2, any translation-covariant Newman Stein metastate for the ground states (i.e., the frequencies with which distinct ground states are observed in finite-size samples in the limit of infinite size, for given disorder) is trivial and unique. In other words, for given disorder and asymptotically at large sizes, the same ground state, or its global spin flip, is obtained (almost) always. The proof consists of two parts: One is a theorem (based on one by Newman and Stein for short-range two-dimensional models), valid for all sigma>1, that establishes triviality under a convergence hypothesis on something similar to the energies of domain walls and the other (based on older results for the one-dimensional model) establishes that the hypothesis is true for sigma>3/2. In addition, we derive heuristic scaling arguments and rigorous exponent inequalities which tend to support the validity of the hypothesis under broader conditions. The constructions of various metastates are extended to all values sigma>1/2. Triviality of the metastate in bond-diluted power-law models for sigma>1 is proved directly. PMID- 29448456 TI - Flow of colloidal suspensions through small orifices. AB - In this work, we numerically study a dense colloidal suspension flowing through a small outlet driven by a pressure drop using lattice-Boltzmann methods. This system shows intermittent flow regimes that precede clogging events. Several pieces of evidence suggest that the temperature controls the dynamic state of the system when the driving force and the aperture size are fixed. When the temperature is low, the suspension's flow can be interrupted during long time periods, which can be even two orders of magnitude larger than the system's characteristic time (Stokes). We also find that strong thermal noise does not allow the formation of stable aggregate structures avoiding extreme clogging events, but, at the same time, it randomizes the particle trajectories and disturbs the advective particle flow through the aperture. Moreover, examining the particle velocity statistics, we obtain that in the plane normal to the pressure drop the colloids always move as free particles regardless of the temperature value. In the pressure drop direction, at high temperature the colloids experience a simple balance between advective and diffusive transport, but at low temperature the nature of the flow is much more complex, correlating with the occurrence of very long clogging events.

AB - We derive an exact law for three-dimensional (3D) homogeneous compressible isothermal Hall magnetohydrodynamic turbulence, without the assumption of isotropy. The Hall current is shown to introduce new flux and source terms that act at the small scales (comparable or smaller than the ion skin depth) to significantly impact the turbulence dynamics. The law provides an accurate means to estimate the energy cascade rate over a broad range of scales covering the magnetohydrodynamic inertial range and the sub-ion dispersive range in 3D numerical simulations and in in situ spacecraft observations of compressible turbulence. This work is particularly relevant to astrophysical flows in which small-scale density fluctuations cannot be ignored such as the solar wind, planetary magnetospheres, and the interstellar medium.

AB - The motility of a cell can be triggered or inhibited not only by an applied force but also by a mechanically neutral force couple. This type of loading, represented by an applied stress and commonly interpreted as either squeezing or stretching, can originate from extrinsic interaction of a cell with its neighbors. To quantify the effect of applied stresses on cell motility we use an analytically transparent one-dimensional model accounting for active myosin contraction and induced actin turnover. We show that stretching can polarize static cells and initiate cell motility while squeezing can symmetrize and arrest moving cells. We show further that sufficiently strong squeezing can lead to the loss of cell integrity. The overall behavior of the system depends on the two dimensionless parameters characterizing internal driving (chemical activity) and external loading (applied stress). We construct a phase diagram in this parameter space distinguishing between static, motile, and collapsed states. The obtained results are relevant for the mechanical understanding of contact inhibition and the epithelial-to-mesenchymal transition. PMID- 29448460 TI - Correlation versus randomization of jerky flow in an AlMgScZr alloy using acoustic emission. AB - Jerky flow in solids results from collective dynamics of dislocations which gives rise to serrated deformation curves and a complex evolution of the strain heterogeneity. A rich example of this phenomenon is the Portevin-Le Chatelier effect in alloys. The corresponding spatiotemporal patterns showed some universal features which provided a basis for a well-known phenomenological classification. Recent studies revealed peculiar features in both the stress serration sequences and the kinematics of deformation bands in Al-based alloys containing fine microstructure elements, such as nanosize precipitates and/or submicron grains. In the present work, jerky flow of an AlMgScZr alloy is studied using statistical analysis of stress serrations and the accompanying acoustic emission. As in the case of coarse-grained binary AlMg alloys, the amplitude distributions of acoustic events obey a power-law scaling which is usually considered as evidence of avalanchelike dynamics. However, the scaling exponents display specific dependences on the strain and strain rate for the investigated materials. The observed effects bear evidence to a competition between the phenomena of synchronization and randomization of dislocation avalanches, which may shed light on the mechanisms leading to a high variety of jerky flow patterns observed in applied alloys.

AB - The transport properties of a bosonic chain have been calculated by placing the ends of the chain in contact with thermal and particle reservoirs at different temperatures and chemical potentials. The contact with the reservoirs is described by the use of a quantum Fokker-Planck-Kramers equation, which is a canonical quantization of the classical Fokker-Planck-Kramers equation. From the quantum equation we obtain equations for the covariances of the creation and annihilation boson operators and solve them in the stationary state for small interactions. From the covariances we determine the Onsager coefficients and in particular the conductance, which was found to be finite for any chain size leading to an infinite conductivity and the absence of Fourier's law.

AB - We consider the steady-state behavior of pairs of active particles having different persistence times and diffusivities. To this purpose we employ the active Ornstein-Uhlenbeck model, where the particles are driven by colored noises with exponential correlation functions whose intensities and correlation times vary from species to species. By extending Fox's theory to many components, we derive by functional calculus an approximate Fokker-Planck equation for the configurational distribution function of the system. After illustrating the predicted distribution in the solvable case of two particles interacting via a harmonic potential, we consider systems of particles repelling through inverse power-law potentials. We compare the analytic predictions to computer simulations for such soft-repulsive interactions in one dimension and show that at linear order in the persistence times the theory is satisfactory. This work provides the toolbox to qualitatively describe many-body phenomena, such as demixing and depletion, by means of effective pair potentials.

AB - The dynamics of coherent nonlinear wave groups is shown to be drastically different from the classical scenario of weakly nonlinear wave interactions. The coherent groups generate nonresonant (bound) waves which can be synchronized with other linear waves. By virtue of the revealed mechanism, the groups may emit waves with similar or different lengths, which propagate in the same or opposite direction.

More recently, attention shifted to higher frequencies, where trades are processed piecewise across different time scales. Here we reveal that price impact has a universal nonlinear shape for trades aggregated on any intraday scale. Its shape varies little across instruments, but drastically different master curves are obtained for order-volume and -sign impact. The scaling is largely determined by the relevant Hurst exponents. We further show that extreme order-flow imbalance is not associated with large returns. To the contrary, it is observed when the price is pinned to a particular level. Prices move only when there is sufficient balance in the local order flow. In fact, the probability that a trade changes the midprice falls to zero with increasing (absolute) order-sign bias along an arc-shaped curve for all intraday scales. Our findings challenge the widespread assumption of linear aggregate impact. They imply that market dynamics on all intraday time scales are shaped by correlations and bilateral adaptation in the flows of liquidity provision and taking.

AB - A well-known stochastic model for intermittent fluctuations in physical systems is investigated. The model is given by a superposition of uncorrelated exponential pulses, and the degree of pulse overlap is interpreted as an intermittency parameter. Expressions for excess time statistics, that is, the rate of level crossings above a given threshold and the average time spent above the threshold, are derived from the joint distribution of the process and its derivative. Limits of both high and low intermittency are investigated and compared to previously known results. In the case of a strongly intermittent process, the distribution of times spent above threshold is obtained analytically. This expression is verified numerically, and the distribution of times above threshold is explored for other intermittency regimes. The numerical simulations compare favorably to known results for the distribution of times above the mean threshold for an Ornstein-Uhlenbeck process. This contribution generalizes the excess time statistics for the stochastic model, which find applications in a wide diversity of natural and technological systems.

AB - In this paper, a general lattice Boltzmann (LB) model is proposed for the high order nonlinear partial differential equation with the form ?_{t}phi+?_{k=1}^{m}alpha_{k}?_{x}^{k}Pi_{k}(phi)=0 (1<=k<=m<=6), alpha_{k} are constant coefficients, Pi_{k}(phi) are some known differential functions of phi. As some special cases of the high-order nonlinear partial differential equation, the classical (m)KdV equation, KdV-Burgers equation, K(n,n)-Burgers equation, Kuramoto-Sivashinsky equation, and Kawahara equation can be solved by the present LB model. Compared to the available LB models, the most distinct characteristic of the present model is to introduce some suitable auxiliary moments such that the correct moments of equilibrium distribution function can be achieved. In addition, we also conducted a detailed Chapman-Enskog analysis, and found that the high-order nonlinear partial differential equation can be correctly recovered from the proposed LB model. Finally, a large number of simulations are performed, and it is found that the numerical results agree with the analytical solutions, and usually the present model is also more accurate than the existing LB models [H.

Using a first-passage-time formulation, in certain system parameter domains exact expressions for the output interspike interval (ISI) density and for the survival probability (the probability that a spike is not generated) are derived and their dependence on input parameters, especially on the memory exponent, is analyzed. In the case of external white noise, it is shown that at intermediate values of the memory exponent the survival probability is significantly enhanced in comparison with the cases of strong and weak memory, which causes a resonancelike suppression of the probability of spike generation as a function of the memory exponent. Moreover, an examination of the dependence of multimodality in the ISI distribution on input parameters shows that there exists a critical memory exponent alpha_{c}~0.402, which marks a dynamical transition in the behavior of the system. That phenomenon is illustrated by a phase diagram describing the emergence of three qualitatively different structures of the ISI distribution. Similarities and differences between the behavior of the model at internal and external noises are also discussed. PMID- 29448470 TI - Optimal design of tweezer control for chimera states. AB - Chimera states are complex spatio-temporal patterns which consist of coexisting domains of spatially coherent and incoherent dynamics in systems of coupled oscillators. In small networks, chimera states usually exhibit short lifetimes and erratic drifting of the spatial position of the incoherent domain. A tweezer feedback control scheme can stabilize and fix the position of chimera states. We analyze the action of the tweezer control in small nonlocally coupled networks of Van der Pol and FitzHugh-Nagumo oscillators, and determine the ranges of optimal control parameters. We demonstrate that the tweezer control scheme allows for stabilization of chimera states with different shapes, and can be used as an instrument for controlling the coherent domains size, as well as the maximum average frequency difference of the oscillators.

AB - Proper location of the mitotic spindle is critical for chromosome segregation and the selection of the cell division plane. However, how mitotic spindles sense cell size and shape to regulate their own position and orientation is still largely unclear. To investigate this question systematically, we used a general model by considering chromosomes, microtubule dynamics, and forces of various molecular motors. Our results show that in cells of various sizes and shapes, spindles can always be centered and oriented along the long axis robustly in the absence of other specified mechanisms. We found that the characteristic time of positioning and orientation processes increases with cell size. Spindles sense the cell size mainly by the cortical force in small cells and by the cytoplasmic force in large cells. In addition to the cell size, the cell shape mainly influences the orientation process. We found that more slender cells have a faster orientation process, and the final orientation is not necessarily along the longest axis but is determined by the radial profile and the symmetry of the cell shape. Finally, our model also reproduces the separation and repositioning of the spindle poles during the anaphase. Therefore, our work provides a general tool for studying the mitotic spindle across the whole mitotic phase. PMID- 29448471 TI - Generation of anisotropy in turbulent flows subjected to rapid distortion. AB - A computational tool for the anisotropic time-evolution of the spectral velocity correlation tensor is presented. We operate in the linear, rapid distortion limit of the mean-field-coupled equations. Each term of the equations is written in the form of an expansion to arbitrary order in the basis of irreducible representations of the SO(3) symmetry group. The computational algorithm for this calculation solves a system of coupled equations for the scalar weights of each generated anisotropic mode. The analysis demonstrates that rapid distortion rapidly but systematically generates higher-order anisotropic modes. To maintain a tractable computation, the maximum number of rotational modes to be used in a given calculation is specified a priori. The computed Reynolds stress converges to the theoretical result derived by Batchelor and Proudman [Quart. J. Mech. Appl. Math. 7, 83 (1954)QJMMAV0033-561410.1093/qjmam/7.1.83] if a sufficiently large maximum number of rotational modes is utilized; more modes are required to recover the solution at later times. The emergence and evolution of the underlying multidimensional space of functions is presented here using a 64-mode calculation. Alternative implications for modeling strategies are discussed. PMID- 29448472 TI - Permutation glass. AB - The field of disordered systems in statistical physics provides many simple models in which the competing influences of thermal and nonthermal disorder lead to new phases and nontrivial thermal behavior of order parameters. In this paper, we add a model to the subject by considering a disordered system where the state space consists of various orderings of a list. As in spin glasses, the disorder of such "permutation glasses" arises from a parameter in the Hamiltonian being drawn from a distribution of possible values, thus allowing nominally "incorrect orderings" to have lower energies than "correct orderings" in the space of permutations. We analyze a Gaussian, uniform, and symmetric Bernoulli distribution of energy costs, and, by employing Jensen's inequality, derive a simple condition requiring the permutation glass to always transition to the correctly ordered state at a temperature lower than that of the nondisordered system, provided that this correctly ordered state is accessible. We in turn find that in order for the correctly ordered state to be accessible, the probability that an incorrectly ordered component is energetically favored must be less than the inverse of the number of components in the system. We show that all of these results are consistent with a replica symmetric ansatz of the system. We conclude by arguing that there is no distinct permutation glass phase for the simplest model considered here and by discussing how to extend the analysis to more complex Hamiltonians capable of novel phase behavior and replica symmetry breaking. Finally, we outline an apparent correspondence between the presented system and a discrete-energy-level fermion gas. In all, the investigation introduces a class of exactly soluble models into statistical mechanics and provides a fertile ground to investigate statistical models of disorder. PMID- 29448473 TI - Enhanced diffusion with abnormal temperature dependence in underdamped space periodic systems subject to time-periodic driving. AB - We present a study of the diffusion enhancement of underdamped Brownian particles in a one-dimensional symmetric space-periodic potential due to external symmetric time-periodic driving with zero mean. We show that the diffusivity can be enhanced by many orders of magnitude at an appropriate choice of the driving amplitude and frequency. The diffusivity demonstrates abnormal (decreasing) temperature dependence at the driving amplitudes exceeding a certain value. At any fixed driving frequency Omega normal temperature dependence of the diffusivity is restored at low enough temperatures, T90% of the total proteins, as determined by SDS-PAGE and densitometric quantification, and their actual molecular weights, determined by mass spectroscopy, were 19,026 and 15,715 Da, respectively, corresponding to the theoretical values. N-terminal amino acid sequencing analyses confirmed the N-terminal conjugation of LMWP to bFGF and VEGF A. Immunoblotting analyses using antibodies against bFGF and VEGF-A, together with the proliferative effects of LMWP-bFGF and LMWP- VEGF-A on human keratinocytes and fibroblasts, demonstrated that the original biological activity of each growth factor was not altered by LMWP conjugation. In addition, the LMWP conjugation did not induce further cytotoxic effects on the skin cells, while the cell membrane-penetrating activities of LMWP-bFGF and LMWP-VEGF-A were significantly enhanced compared with the respective unconjugated growth factors. These results suggest that LMWP-bFGF and LMWP-VEGF-A can be used as effective topical therapeutic or cosmetic agents for skin regeneration and anti-aging treatments.

AB - In this in vitro study, nystatin-alginate microparticles were successfully fabricated to control the release of nystatin from a commercial dental tissue conditioner. These nystatin-alginate microparticles were spherical and had a slightly rough surface. The microparticles incorporated into the tissue conditioner were distributed homogeneously throughout the tissue conditioner matrix. The incorporation of the microparticles did not deteriorate the mechanical properties of the original material. The agar diffusion test results showed that the tissue conditioner containing the microparticles had a good antifungal effect against Candida albicans. The nystatin-alginate microparticles efficiently controlled the release of nystatin from the tissue conditioner matrix over the experimental period of 14 days. Moreover, the nystatin-alginate microparticles incorporated in the tissue conditioner showed effective antifungal function even at lower concentrations of nystatin. The current study suggests that the tissue conditioner containing the nystatin-alginate microparticle carrier system has potential as an effective antifungal material. PMID- 29448505 TI - Novel beta-TCP Coated Titanium Nanofiber Surface for Enhanced Bone Growth. AB - In this study, we examined the effect of beta-tricalcium phosphate (beta-TCP) coating on alkali-treated CP Grade II titanium surface via RF magnetron sputtering on osteoblast like cell (MC3T3-E1) viability and bone formation in rat tibia. The specimens were divided into three groups; commercially pure titanium (control group), alkali-treated titanium with nanofiber structure (NF group) and beta-TCP coating on alkali-treated titanium with nanofiber structure (TNF group). The surface characteristics of specimens were observed under a field emission scanning electron microscope (FE-SEM), and contact angle was measured. The cell viability was assessed in vitro after 1 day, 3 days and 7 days. Implants of 2.0 mm diameter and 5.0 mm length were inserted into the tibia of rats. After 4 wks, the histomorphometric analysis was performed. Group NF and group TNF showed improved hydrophilicity of Ti. Group TNF showed significantly higher cell viability (P < 0.05) after 7 days. The bone to implant contact (BIC) ratio of the control group, NF group, and TNF group were 32.3%, 35.5%, and 63.9%, respectively. The study results suggested that beta-TCP coated alkali-treated titanium surface via RF magnetron sputtering might be effective in implant dentistry due to enhanced hydrophilicity, improved cell response, and better osseointegration.

AB - Organic/inorganic biocomposite materials for biodegradable fixation medical devices require osteoconductivity, biocompatibility, and adequate mechanical properties with biodegradation behavior. The objective of this study was to investigate the effect of Si ions substituted in beta-tricalcium phosphate (beta TCP) on the mechanical properties of organic/inorganic biocomposites. Biodegradable composite materials were prepared with polylactic acid (PLA) as the matrix and nano Si-substituted beta-TCP as the osteoconductive filler by solvent mixing and conventional molding. The nanostructured Si-substituted beta-TCP powders were synthesized by co-precipitation, controlling the quantity of Si ions. The amount of nanostructured Si-substituted beta-TCP powders in composites was varied in the 0-40 wt% range and the material properties were compared with those of pure beta-TCP/PLA composites. The influence of Si ions on the mechanical properties of the composites was evaluated by tensile and flexural tests. PMID- 29448507 TI - Platinum Nanoparticles Induce Apoptosis on Raw 264.7 Macrophage Cells. AB - The cellular effects of platinum nanoparticles (PNP05, average size of 5 nm, and PNP30, average size of 30 nm) were investigated on murine leukemia Raw 264.7 cells. Cells treated with various concentrations of PNPs showed size-dependent cytotoxicity in an MTT assay with PNP5 of smaller nanoparticles higher toxicity than PNP30. Investigations on cell morphology, Annexin V assay, DNA fragmentation and the activity of caspase-3/-7 showed that PNPs induced apoptosis on Raw 264.7 cells by changing cell morphology and density, increasing cell population in apoptosis and causing nucleus fragmentation. Further study on caspase activity by Western blotting revealed that the apoptosis was induced by the activation of caspase-3 and -7. In addition, PNPs inactivated DNA repair system, generating dose-dependent DNA ladder bands on agarose gel electrophoresis. Taken together, PNPs triggered cytotoxicity on Raw 264.7 cells by suppressing cell growth/survival and inducing apoptosis. PMID- 29448508 TI - In Vivo; In Vitro Interaction of Silver Nanoparticles with Leucine Aminopeptidase from Human and Plasmodium falciparum. AB - There is increasing requirement for the development of new drug protocols against malaria, a fatal disease caused by the lethal parasite Plasmodium falciparum. Leucine aminopeptidase (Pf LAP) of Plasmodium falciparum, is being pursued as a promising target for the discovery of novel antimalarials. The effects of silver nanoparticles (AgNPs) against P. falciparum leucine amino-peptidase (Pf LAP) and the human homolog (HsLAP) were compared. Pf LAP and HsLAP were expressed in Escherichia coli, and AgNPs (3-10 nm) characterized by ultra-violet spectroscopy and transmission electron microscopy. Pf LAP indicated a Km of 694 MUM towards leucine-p-nitroanilide and a Vmax of 57.9 MUmol.ml-1 . min-1 while HsLAP had a Km of 1.6 mM and Vmax of 119.6 MUmol . ml-1 . min-1. On interaction with AgNPs (670 nM) Pf LAP was selectively inhibited (57.1%; Ki = 610 nM) relative to HsLAP (10.8%; Ki = 5.22 MUM). Structural differences between the enzyme variants, particularly the orientation and distance of surface Met349 in Pf LAP and Met306 in HsLAP to the zinc binding sites were significant and may allow for selective targeting of Pf LAP by AgNPs. The viability of P. falciparum parasites was decreased when exposed to silver nanoparticles, with an IC50 value of 6.96 MUM, compared to an IC50 value of 647.7 MUM for human HeLa cells. PMID- 29448509 TI - Nicotinic Acid Coated Magnetite Nanorods Evaluation by Lipid Profile Analysis and Genetic Tests. AB - In our present work some biological tests were carried out to assess the biocompatibility of nicotinic acid coated magnetite nanorods. Pure and coated nanorods were injected intraperitoneally to cholesterol fed mice with dose values of 25, 50 mg/Kg. Investigations were done on treated mice with/without exposure to low frequency electromagnetic field (EMF) and samples were collected fourteen days post treatment. Toxicological effects were evaluated using Micronucleus and DNA fragmentation analysis. The results indicated that low dose (25 mg/Kg) nicotinic acid coated nanorods had insignificant toxicological effects in comparison to that of control group. Lipid profile analysis and gene expression of atheroprotective (eNOS) and atherogenic (p65) genes were also investigated. It was found that experimental groups treated with low dose nicotinic acid coated magnetite nanorods and exposed to EMF showed interesting alterations in mice lipid profile. As a result, an insignificant but slight increase in gene expression levels of eNOS and a significant decrease in p65 gene expression were observed. Our study suggests that our proposed magnetic nanosystem in combination with EMF has good biocompatibility and can be a potential drug precursor with therapeutic values. PMID- 29448510 TI - Preparation and In Vivo Biodistribution of Ultra-Small Superparamagnetic Iron Oxide Nanoparticles with High Magnetic Targeting Response. AB - The ultra-small superparamagnetic iron oxide (USPIO) particles with high saturation magnetization and good superparamagnetism were prepared by reverse micro-emulsions using novel C16E15 as surfactant, which can reduce magnetic dipole-dipole interaction, hence decreasing the critical blocking temperature (TB). Powder X-ray diffraction (XRD), Infrared spectrum (FT-IR), Transmission electron microscope (TEM), X-ray photoelectron spectroscopy (XPS), and Vibrating sample magnetometer (VSM) were used to characterize the magnetic particles. The higher ratio of Fe2+/Fe3+ caused redundant FeO on the USPIO surface. An in vitro approach model for simulating target delivery of USPIO particles to sites of interest was developed to illustrate the relationship between magnetic fluid retention rate and pole distance. In Vivo targeted interception and magnetic targeting bio-distribution of superparamagnetic particles were also investigated simultaneously. The results indicated that the USPIO had high ability for magnetic focusing in mimetic surrounding tissue surrounding blood vessels under the action of pulsed magnetic field. The USPIO nanoparticles will be fundamental in biomedical applications. PMID- 29448511 TI - Preparation and In Vitro Evaluation of Elastic Nanoliposomes for Topical Delivery of Highly Skin-Permeable Growth Factors. AB - Percutaneous delivery of growth factors is often used to treat wounds, and for cosmetic purposes, as a way of accelerating healing and skin regeneration, respectively. However, the therapeutic effects of growth factors are diminished by their poor absorption when delivered percutaneously, in addition to their rapid degradation by proteinases. To overcome these obstacles, we constructed two skin-permeable compounds. Basic fibroblast growth factor (bFGF) and vascular endothelial growth factor-A (VEGF-A) were both genetically paired with low molecular-weight protamine (LMWP), to yield the compounds LMWP-bFGF and LMWP-VEGF A, respectively. The molecular weights and N-terminal amino acid sequences of LMWP-bFGF and LMWP-VEGF-A confirmed that the N-terminus-specific conjugation of LMWP with bFGF and VEGF-A had been successful. The biological abilities of the native factors to stimulate human fibroblast (CCD-986sk) and endothelial cell proliferation were preserved. Both compounds significantly promoted wound (scratch) recovery and enhanced procollagen type I C-peptide synthesis in CCD 986sk cells (to levels 184 and 133% those of the native compounds, respectively). The LMWP-conjugated growth factors were significantly more permeable than the native forms (by 7.29- and 29.22-fold, respectively). Finally, encapsulation of the compounds in positively charged elastic nanoliposomes (115 +/- 1.54 nm in diameter with a zeta potential of 57.2 +/- 3.05 mV) further improved both permeation and stability. Thus, nanoliposomes loaded with LMWP-conjugated growth factors are expected to enhance skin regeneration; the materials will find applications in wound-healing therapies and anti-wrinkle cosmetics. PMID- 29448512 TI - Thymosin beta4 Reduces H2O2 Induced Oxidative Stress in MC3T3-E1 Cells on Titanium Surface. AB - Thymosin beta4 (Tbeta4) is known to inhibit an inflammatory response and to increase the survival of osteoblasts on titanium (Ti) surfaces. Ti is the most widely used graft material in dentistry; however, an inflammatory response induced following implant placement results in the generation of reactive oxygen species (ROS). The oxidative stress from the production of ROS such as nitric oxide (NO) and hydrogen peroxide (H2O2) can damage surrounding cells, resulting in implant failure by decreasing cell viability. Thus, the aim of this study was to determine the biological effects of Tbeta4 on the oxidative stress induced to MC3T3-E1 preosteoblasts on the Ti surface. Based on an MTT assay and bromodeoxyuridine immunofluorescence staining, Tbeta4 was found to increase the proliferation of the H2O2-exposed MC3T3-E1 cells on Ti discs. Reverse transcription-polymerase chain reaction and western blot analyses showed that Tbeta4 decreased the mRNA and protein expression levels of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in H2O2-exposed MC3T3-E1 cells on the Ti discs. Tbeta4 inhibited the synthesis of intracellular ROS and the secretion of NO and prostaglandin E2 (PGE2) from H2O2-exposed MC3T3-E1 cells on the Ti discs. In conclusion, Tbeta4 inhibits H2O2-induced iNOS and COX-2 expression with a decrease in ROS, NO, and PGE2 synthesis, which leads to improved cell survival with low cytotoxicity under an oxidative stress condition in MC3T3-E1 cells on the Ti surface. This suggests that Tbeta4 may be a crucial molecule to reduce oxidative stress-induced cell damage or hypoxia, leading to promoted osseointegration on the Ti surface during implant placement. PMID- 29448514 TI - Facile One-Pot Synthesis of Graphene Oxide by Sonication Assisted Mechanochemical Approach and Its Surface Chemistry. AB - Facile one pot synthesis of graphene oxide (GO) by sonication assisted mechanochemical approach has been reported here. The amalgamation of ultrasonication and mechanical stirring has assisted the synthesis of GO in a short time duration of only 4 hours with good reaction yield. The structural characterization of GO was performed by X-ray diffraction spectroscopy (XRD), Fourier transform infrared spectroscopy (FTIR), UV-Visible spectroscopy and Raman spectroscopy. Atomic force microscopic (AFM) analysis manifested the flake like morphology of GO with average sheet thickness ~1.5 nm. AFM also provides important information about the surface roughness. Transmission electron microscope (TEM) analysis gave clear visualization of well exfoliated structure of GO in the form of thin flakes. The field emission scanning electron microscope (FESEM) analysis revealed a crimpling surface morphology of GO. The average size of GO flake as revealed through various morphological as well as light scattering techniques was around 3 MUm. Moreover, important surface chemistry of the synthesized GO was well ascertained through contact angle analysis, AFM analysis and zeta potential analysis. PMID- 29448513 TI - Removing Control of Cyclodextrin-Drug Complexes Using High Affinity Molecule. AB - Nanostructured supramolecular assemblies with hydrophobic cavities are used for improving the solubility, bioavailability, and stability of poorly water soluble drugs. In particular, host-guest inclusion using 2-hydroxypropyl-beta cyclodextrin (HP-beta-CD) is a typical approach in the pharmaceutical field. In this study, celecoxib (CXB), a cyclooxygenase-2 selective nonsteroidal anti inflammatory drug (NSAID), was used as the model drug (guest material) and effectively incorporated into HP-beta-CD (host material). After forming a complete complex of HP-beta-CD and CXB, 1-adamantylamine (ADA) was used to allow CXB to be released from the HP-beta-CD in a concentration-dependent manner. This was revealed from Fourier-transform infrared spectroscopy and drug dissolution studies. Notably, the use of ADA, which is a high-affinity guest molecule, with cyclodextrin accelerated the removal of CXB from the host material through the exchange of guest molecules. Taken together, the host-guest based approach using a second guest molecule is useful for regulating on-demand drug release and could therefore be a potential tool for biomedical applications. PMID- 29448515 TI - Polyalkylene Glycol Based Lubricants and Tribological Behaviour: Role of Ionic Liquids and Graphene Oxide as Additives. AB - The polyalkylene glycol (PAG) lubricants are widely used as gear, bearing and compressor oils in refrigerant systems. They are designed to provide outstanding benefits in terms of efficiency, long oil life, and equipment protection. These fully synthetic lubricants have been developed for use under operating conditions beyond the capabilities of other synthetic lubricants and mineral oils as their characteristic low pour point ensures excellent fluidity at low-temperature. On the other hand, the main drawback of PAG oils is the marked hygroscopicity, i.e., they absorb and bind moisture from the ambient air. In this paper, the results from tribological testing of PAG oil featuring 46 cSt at 40 degrees C with solid (graphene oxide) and liquid (ionic liquids) additives are discussed. Moreover, in this study the influence of absorbed moisture from ambient air has been investigated. Preliminary experiments with ball-on-flat setup by using reciprocatory tribometer tested the response of base oil PAG 46 blended with 1 Ethyl-3-methylimidazolium acetate or graphene oxide, alternatively. In such a way, the individual influence of each additive was questioned. Based on preliminary analysis, this research focuses on hybrid formulations to substantiate potential improvements of anti-friction and anti-wear PAG 46 performance over broad range of lubrication regimes. Experimental tests have been carried out by using rotational disc tribometer in ball-on-disc configuration. Additional experiments after samples exposure to ambient air and ensuing moisture absorption were carried out. The results highlight that in most cases limited absorbed moisture does not introduce detrimental effects on the tribological performances of the tested oil samples: indeed, water content could reduce wear of the sliding steel surfaces over the whole testing spectrum and in most of the cases the frictional energy dissipation. PMID- 29448516 TI - Mesoporous Ga-TiO2: Role of Oxygen Vacancies for the Photocatalytic Degradation Under Visible Light. AB - Gallium doped mesoporous TiO2 with different weight percentages were synthesized by sol-gel method using Pluronic P123 as the structure directing template. The physico-chemical properties of all the synthesized catalysts were determined by XRD, TEM, SEM-EDAX, N2 adsorption-desorption studies, XPS, UV-vis DRS, FT-IR and photoluminescence spectroscopy. 1.0 wt% Ga-TiO2 exhibited the highest photocatalytic efficiency among all the synthesized materials under visible light due to the high surface area, reduced band gap and suppressed electron-hole recombination. Ga3+ ions substitutions for Ti4+ ions in TiO2 lattice created oxygen vacancies in TiO2 lattice, which created a defect energy level below the conduction band of TiO2 and hence the band gap was reduced. The oxygen vacancy defects was playing significant role to improve the adsorption of oxygen molecules, hydroxide ions and cationic rhodamine B (RhB) on TiO2 surface in an aqueous medium. The lifetime of the charge carriers was also enhanced by trapping the photogenerated electrons in oxygen vacancies and transferring them to the adsorbed O2 to produce superoxide anion radicals (O-. 2 ). The photo-induced holes at valence band reduced the adsorbed OH- ions and produced a large number of .OH radicals, which subsequently degraded the RhB. Hence oxygen vacancies created by gallium doping on TiO2 enhanced the photocatalytic efficiency for the degradation of RhB under visible light.

AB - Polyurethane (PU) foams with controlled porosity and pore structure are prepared via judicious study on expanding process parameters for thermoplastic expandable microspheres which are compatible with PU synthetic process. Thermal and mechanical properties of PU foams are found to be generally governed by amount of the porosity. Thermal conductivity of PU foams with controlled porosity is measured at 30 degrees C with transient hot bridge method. The measured thermal conductivity of PU foams is estimated using theoretical models, proving the formation of spherical pore structures of expandable microspheres in PU matrix and serving as an internal porous material. PMID- 29448518 TI - Effect of Aspect Ratio on Electrical, Rheological and Glass Transition Properties of PC/MWCNT Nanocomposites. AB - Since the discovery of carbon nanotubes (CNT), significant research works have focused on the application of CNT as conductive filler to polymer nanocomposites which can be used in several fields such as electrostatic dissipation (ESD), electrostatic painting and electromagnetic interference shielding (EMI shielding). However, the main challenge in the large-scale manufacturing of this technology is the poor electrical conductivity of polymer nanocomposites produced by injection molding process. This study aims to investigate the effect of CNT aspect ratio in improving the electrical conductivity of injection molded nanocomposites. In this work, three types of multiwall carbon nanotubes with different lengths were melt-mixed with polycarbonate in a twin screw extruder followed by injection and compression molding. Results show that nanocomposites with higher CNT aspect ratio exhibit higher electrical conductivity. Longer nanotubes form a stronger conductive network during secondary agglomeration which can withstand the high shear forces during injection molding. Higher melt viscosity and storage modulus were observed in nanocomposites with higher CNT aspect ratio which is attributed to the effective constriction of polymer chains by longer nanotubes. It was also found that Tg of the composites increased with nanotube aspect ratio and the addition of CNT causes degradation which leads to the general Tg depression of polycarbonate. PMID- 29448519 TI - Peroxidase-Like Activity of Gold Nanoparticles and Their Gold Staining Enhanced ELISA Application. AB - We found that the peroxidase-like activity of gold nanoparticles (GNPs) followed the Michaelis-Menten kinetic model and was dependent on environmental pH and temperature, which was very similar to natural Horseradish Peroxidase (HRP). However, unlike HRP, which needs a lower H2O2 concentration with a very narrow range to reach a maximum reaction rate and avoid enzyme poisoning, GNPs have very high activity, even at an H2O2 concentration two orders of magnitude higher than HRP. It was demonstrated that H2O2 treatment could enhance the peroxidase-like activity of GNPs, resulting thus in the activity increase in a circular catalytic reaction by the reduplicative use of GNPs. It was also found that the peroxidase like activity of GNPs responded sensitively to nanoparticle size and surface modifications. When used in an immunoassay, GNPs were generally conjugated with antibody and blocked with hydrophilic macromolecules to construct a nanoprobe. This strongly reduced the peroxidase-like activity and detection sensitivity of GNPs, therefore, restricting their use as peroxidase mimetics. We presented a novel strategy that combined the nanoprobes with gold staining to expose fresh catalytic gold surfaces and obtained a great increase in detection sensitivity. PMID- 29448520 TI - Synthesis of Fluorophore Decorated Single-Walled Carbon Nanotubes for In-Vitro Cytocompatibility. AB - We report rhodamine based fluorophore derivative for the stable dispersion of single-walled carbon nanotubes (SWCNTs), which can afford better fluorescent label to carbon nanotubes (CNTs). The nanotubes-fluorophore conjugates are helpful in achieving stable dispersion in polar and non-polar solvents with intense fluorescence. The product was characterized through NMR, Mass spectrometry, Raman, XPS, SEM, AFM and Fluorescence measurements. The formation of SWCNT-g- Rhodamine was confirmed by the presence of D and G bands in Raman spectrum. The alkyl and aryl groups in the range of 14.8, 17.6, 38.1 and 96.3 ppm confirms the grafting of the nanocomposite through NMR. The morphological studies were carried out intensively for analyzing SWCNTs stable dispersion and the results from EDAX measurements shows the elements weight% of C: 35.09 and N: 30.1 concludes that SWCNTs are completely grafted onto rhodamine derivatives. The application of SWCNTs fluorophore conjugates were analyzed by cell viability studies using MTT assay and exhibits less toxic compare to other functionalized CNTs. The viability of percentage increases with decrease in the concentration of SWCNT-COCl with 91.7% of live cells even after 24 h at a concentration of 250 MUg for SWCNT-g-Rhodamine. The fluorescent images obtained during viability analysis shows enhanced fluorescence for living cells in case of SWCNT-g-Rhodamine compared to SWCNT-COCl, which clearly shows the utility of decorating nanotubes with fluorophore. This research work further extends its application for molecular sensing and other biological process. PMID- 29448521 TI - Effect of Ammonium Salts on the Hydrothermal Synthesis of TiO2 Nanocubes for Dye Sensitized Solar Cells. AB - TiO2 nanocubes were synthesized via hydrolysis condensation of titanium tetra isopropoxide (TTIP) in aqueous media, followed by hydrothermal treatment with ammonium salts. Various ammonium salts with different alkyl chain such as ammonium hydroxide (NH4OH), tetramethylammonium hydroxide (TMAH), tetraethylammonium hydroxide (TEAH) and tetrabutylammonium hydroxide (TBAH) were investigated. The crystalline phase, shape, and morphology of TiO2 nanocubes were studied by XRD, TEM, and SEM analysis. These TiO2 nanocubes were pure anatase phase and tended to assemble with well-ordered and close-packed domains. Both alkyl chain length of ammonium salts and hydrothermal duration affected the TiO2 nanocube formation process. The ammonium salts with longer alkyl chain formed TiO2 nanocubes in shorter hydrothermal time and offered the smallest particle size. The above TiO2 nanocubes were applied as photoanode materials in N719 anchored dye-sensitized solar cells and one of the cells exhibited the maximum power conversion efficiency of 7.85%. PMID- 29448522 TI - Effect of Graphene/TiO2 Composite Layer on the Performance of Dye-Sensitized Solar Cells. AB - Graphene has attracted a lot of attention because of its unique mechanical, thermal, electrical and optical properties. In this study, a double layered structured photoanode consisting of a graphene/TiO2 composite layer and a TiO2 nanoparticles (P25) underlayer was developed. The photoelectric properties of as prepared double layer structured photoanode were studied with comparison of the anatase TiO2 photoanode. Graphene was prepared by reduction of graphene oxide (GO) under a hydrothermal conditions and graphenen/TiO2 composite semiconductor materials were prepared by mixing graphene into TiO2 paste. The effect of graphene contents in graphene/TiO2 composite layer was also investigated. After constructing double layer photoanode with proper amount of graphene, the photoanode displayed enhanced light and dye adsorption properties with higher light harvesting efficiency, lower internal resistances, faster electron transport and lower charge recombination rate, which resulted in high current density. At the optimum conditions, the DSSC exhibited a Jsc of 15.01 mA cm-2, a Voc of 0.72 V, and a FF of 0.66 with the energy conversion efficiency (eta) of 7.08%, indicating a increase in Jsc and eta respectively than that of DSSC based on pure TiO2 photoanode, which gives a Jsc of 13.25 mA cm-2, a Voc of 0.73 V, and a FF of 0.62 with a eta of 5.94%. However, the addition of excess graphene in the composite layer led to the enhancement of charge recombination, the reduction of dye adsorption and the decrease of photoelectric conversion efficiency of DSSCs. The graphene/TiO2 composite layer in DSSCs could really enhance its efficiency after the amount of graphene was successfully optimized. PMID- 29448523 TI - Mimicking the Synaptic Weights and Human Forgetting Curve Using Hydrothermally Grown Nanostructured CuO Memristor Device. AB - In the present investigation, we have fabricated copper oxide (CuO) thin film memristor by employing a hydrothermal method for neuromorphic application. The X ray diffraction pattern confirms the films are polycrystalline in nature with the monoclinic crystal structure. The developed devices show analog memory and synaptic property similar to biological neuron. The size dependent synaptic behavior is investigated for as-prepared and annealed CuO memristor. The results suggested that the magnitude of synaptic weights and resistive switching voltages are dependent on the thickness of the active layer. Synaptic weights are improved in the case of the as-prepared device whereas they are inferior for annealed CuO memristor. The rectifying property similar to a biological neuron is observed only for the as-prepared device, which suggested that as-prepared devices have better computational and learning capabilities than annealed CuO memristor. Moreover, the retention loss of the CuO memristor is in good agreement with the forgetting curve of human memory. The results suggested that hydrothermally grown CuO thin film memristor is a potential candidate for the neuromorphic device development.

AB - LiFePO4 electrodes using three dimensional NiCrAl alloy metal foam of different electrode thickness are prepared. In order to improve the electrochemical and cycle-life performance of lithium ion batteries, it is important to optimize the electrode thickness and mass loading of active material. As compared to those with thick electrode, the cells with thin electrode exhibit high rate performance and cycle-life behavior, due to the shorter diffusion length of lithium-ion and improved kinetic behavior. Also, cyclic voltammetry curves and electrochemical impedance spectroscopy analysis indicate that the redox reaction for the thinner electrode occurs much faster, and the charge transfer resistance is much lower. The results of same current density (mA cm-2) show that 450 MUm-thickness electrode exhibits superior electrochemical and power performance. It is because the 300 MUm-thickness electrode which has the lowest mass loading of active material meant that it carried the highest current rate, and thicker electrodes show higher internal resistance and much poorer kinetic property. Namely, electrode thickness and an amount of active material are difference according to the intended use.

AB - Zn2SnO4-reduced graphene oxide photocatalysts were synthesized by using SnCl4 5H2O, Zn(NO3)2 . 6H2O and graphene oxide via hydrothermal process. The structure, morphology, specific surface area and photo response of the as-prepared nanocomposites were characterized by X-ray diffraction, Transmission electron microscopy, UV-vis diffuse reflectance spectra, Brunauer-emmett-teller surface area measurement and Photoluminescence emission spectra. Experimental results showed that the Zn2SnO4 nanoparticles, with 20-30 nm a size range, were uniformly dispersed on the surfaces of reduced graphene oxide. Moreover, the as-prepared Zn2SnO4-reduced graphene oxide photocatalysts exhibited enhanced photocatalytic activities for degradation of Rhodamine B compared to those of pure Zn2SnO4. When the amount of reduced graphene oxide was 4 wt%, it showed the highest photocatalytic efficiency of 99.7% for 240 min, and the photocatalytic efficiency was still 98.5% after it was recycled 4 times. It also possessed the band gap of 2.48 eV and specific surface area of 58.1 m2 g-1.

AB - Composites of multi-walled carbon nanotubes (MWCNTs) and poly(3,4 ethylenedioxythiophene) (PEDOT) are attracting the attention of material scientists since more than a decade as potential next-generation optoelectronic materials for their peculiar features, arising from the combination of the intrinsic electrical, thermal and morphological properties of the two components. They are indeed a promising platform for the development of low-cost, portable and environmentally friendly electronic devices such as supercapacitors, sensors and actuators. Here a novel synthetic strategy for their preparation is envisaged, exploiting the possibility to covalently functionalize the external surface of MWCNTs with tailored molecular units, starting from which the growth of the conjugated polymer can be induced oxidatively. The approach demonstrates its value in being able to effectively promote the formation of PEDOT chains in direct contact with the surface of MWCNTs, differently from what results when the monomer is polymerized in the presence of the pristine carbon nanomaterial. In addition, significant differences are found in the physico-chemical properties and electrochemical behavior when MWCNT-PEDOT covalent composites are studied in comparison to a non-covalent analogue, here illustrated in detail. These evidences constitute a starting point for the future development of novel more finely tuned functional materials based on MWCNT-PEDOT composites, featuring the required optoelectronic properties to precisely target the desired application.

AB - Ni-doped cobalt aluminate NixCo1-xAl2O4 (x = 0.0, 0.2, 0.4, 0.6, 0.8 and 1.0) spinel nanoparticles were successfully synthesized by a simple microwave combustion method using urea as the fuel and as well as reducing agent. X-ray powder diffraction (XRD) was confirmed the formation of single phase, cubic spinel cobalt-nickel aluminate structure without any other impurities. Average crystallite sizes of the samples were found to be in the range of 18.93 nm to 21.47 nm by Scherrer's formula. Fourier transform infrared (FT-IR) spectral analysis was confirmed the corresponding functional groups of the M-O, Al-O and M Al-O (M = Co and Ni) bonds of spinel NixCo1-xAl2O4 structure. Scanning electron microscope (SEM) and transmission electron microscope (TEM) images was confirmed the particle like nanostructured morphology. Energy band gap (Eg) value was calculated using UV-Visible diffuse reflectance spectra (DRS) and the Eg values increased with increasing Ni2+ dopant from x = 0.2 (3.58 eV) to x = 1.0 (4.15 eV). Vibrating sample magnetometer (VSM) measurements exposed that undoped and Ni doped CoAl2O4 samples have superparamagnetic behavior and the magnetization (Ms) values were increased with increasing Ni2+ ions. Spinel NixCo1-xAl2O4 samples has been used for the catalytic oxidation of benzyl alcohol into benzaldehyde and was found that the sample Ni0.6Co0.4Al2O4 showed higher conversion 94.37% with 100% selectivity than other samples, which may be due to the smaller particle size and higher surface area. PMID- 29448528 TI - Removal of Waterborne Pathogen by Nanomaterial-Membrane Coupling System. AB - The waterborne pathogenic viruses threaten human health. And the nanomaterial membrane coupling system is promising in virus removal. In this study, phage MS2 was selected as the model virus to investigate the removal of virus with the coupling system. Results revealed that commercial nano TiO2 (Degussa Aeroxide P25) showed both of excellent adsorption and photocatalysis performance for virus removal compared with nano ZnO, nano Fe3O4, carbon nanotube, graphene, nano Ni and Nano TiO2 (anatase). In P25 photocatalysis process, the removal efficiency of phage MS2 increased with the increase of P25 concentration (0~1000 mg L-1), virus initial concentration (102~106 PFU mL-1), UV irradiation doses (5~120 mJ cm-2) and UV light intensity (0.126~0.742 mW cm-2). However, when the P25 concentration increased to over 1000 mg L-1, the virus removal efficiency would remain stable with the increase of P25 concentration. The nanomaterial-membrane coupling system showed excellent performance for virus removal, which was mainly attributed to the adsorption and photocatalysis of P25, and the intercept of membrane. When the P25 concentration was 100 mg L-1, UV irradiation dose was 20 mJ cm-2 and transmembrane pressure was 20 kPa, the phage MS2 removal efficiency could be up to 100%.

AB - Carbons spheres, easily fabricated by glucose hydrolysis, were integrated with alpha-Fe2O3 for removing heavy metal from contaminated water. The alpha-Fe2O3 particles were anchored on the surface of carbon spheres and the combination of two components provided more rough surface area, enhancing the adsorption performance of alpha-Fe2O3. The removal efficiency of Cr(VI) on alpha Fe2O3/carbon spheres was 88% in 240 min, which was 1.93 times higher than that of pristine alpha-Fe2O3. The investigation on adsorption kinetics and isotherm showed that the pseudo-first-order kinetic and Langmuir isotherm models could well fit the experimental data. The adsorption rate was mainly controlled by both exterior and interior surface diffusion steps. Adsorption thermodynamics investigation proved that the Cr(VI) adsorption on alpha-Fe2O3/carbon spheres was an endothermic (93.32 kJ . mol-1) and spontaneous (-3.96 kJ . mol-1) physical process. The adsorption capacity was 18.7 mg . g-1 and after recycling five times, the decline of adsorption capacity of alpha-Fe2O3/carbon spheres was 7.8%, which indicated that the adsorbents could be recycled in the removal of Cr(VI). It indicated that the hybridization with carbon spheres could enhance the adsorption performance of alpha-Fe2O3, which might be used as convenient adsorbent to remove heavy metal in industry.

AB - Samarium (Sm3+)-doped LaF3 nanoparticles (NPs) subsequently encapsulated with inert crystalline LaF3 and amorphous silica layers were prepared by polyol and sol-gel chemical process, respectively. These surface modified core/shell/SiO2 nanostructured were characterized by X-ray diffraction (XRD), FE-transmission electron microscopy (TEM), thermal analysis, FTIR, UV/Vis absorption, bang gap energy and photoluminescence spectroscopy. The FETEM, EDX and FTIR spectral studies clearly revealed that the silica layer has been formed surrounding the core-NPs. Comparative spectral analysis indicated that core/shell/SiO2-NPs revealed high solubility in aqueous and non-aqueous solvents. The decrease in band gap energy after surface growth of an inert LaF3 and silica shells is directly correlated to the increase in grain size. On comparing the emission intensity, a significant enhancement was observed after inert layer coating, whereas, it suppress after silica encapsulation due to the non-radiative transitions. The increase luminescent intensity after inert shell growth indicates that a significant amount of non-radiative centers existing on the surface of core/shell nanoparticles can be eliminated by the shielding effect of LaF3 shells. These observed results indicate that the as-prepared core/shell/SiO2 NPs could be highly useful in broad photonic based applications such as optical sensor/optical bio-probe and light emitting diode.

AB - NiAl layered double hydroxide (NiAl-LDH) was synthesized by co-precipitation method. And sodium dodecyl sulphate (SDS) as modifier was utilized to enlarge the d-spacing of NiAl-LDH to obtain SDS-NiAl-LDH. PP/SDS-NiAl-LDH nanocomposites were prepared with different amount of SDS- NiAl-LDH and PP by melt intercalation method. The results of XRD and TEM confirmed that intercalated and exfoliated intercalated structures were formed. Compared with pure PP, PP/SDS- NiAl-LDH nanocomposites exhibited high thermal stability and residual to the presence of barrier effect of NiAl-LDH layers. Cone calorimetry analysis indicated that incorporation of SDS-NiAl-LDH obviously improved flame retardancy and smoke suppression properties of PP. With the addition of 5 wt% SDS-NiAl-LDH, the peak heat release rate (PHRR), the total heat release (THR) and smoke production rate (SPR) peak values reduced 32.4%, 16.0%, and 61.5% compared with those of pure PP, which were attributed to the barrier effect and excellent charing performance of SDS-NiAl-LDH.

AB - Anatase hierarchical TiO2 microsphere/carbon dots composite (HTM/CDs) was fabricated by a facile method for active visible light photocatalysis. The phase, morphology, microstructure and optical properties were investigated by X-ray diffraction, scanning electronmicroscopy, transmission electron microscopy and UV VIS diffuse reflectance spectroscopy respectively. Under visible light illumination, the fabricated HTM/CDs composite was exhibited an enhanced photo catalytic activity compared to that of pure hierarchical TiO2 microspheres (HTM). Such an enhancement in photocatalytic activity can be attributed to an increase in the absorption of visible light. The photocatalytic activity was investigated by the degradation of a model dyemalachite green (MG) and oxygen production through water splitting.We believe that this type of hybrid material could be used as a highly active and stable visible light photocatalyst to remove pollutants as well as energy production with high performance.

AB - Quantum dots have recently been adopted in display devices for color compensation with light emitting diodes (LEDs). One of the major limitations in using QDs is the thermal instability of photoluminescence (PL) owing to the heat dissipation of LEDs. In this study, transparent hybrid films of ZnO quantum dots (QDs) dispersed in poly(methyl methacrylate) (PMMA) with silica were prepared, and the thermal stability of the fluorescence of the films was investigated. ZnO QDs were synthesized by a thermal decomposition process and exhibited a PL emission peak at 475 nm with excitation at 320 nm. The ZnO QDs were spherical in shape with an average diameter of 3 nm. The PL intensity of the ZnO QD-PMMA films decreased with an increase in temperature. With increased silica content in the ZnO QD PMMA/silica films, the PL quenching was reduced.

AB - A mesoporous material, Al-MCM-41, was applied to the catalytic pyrolysis of municipal plastic film waste (MPFW) to produce large amounts of valuable hydrocarbons. Compared to non-catalytic pyrolysis, the catalytic pyrolysis of MPFW over Al-MCM-41 revealed a lower decomposition temperature and activation energy upon thermogravimetric analysis. Heavy aliphatic hydrocarbons, which are the major products of non-catalytic pyrolysis, were cracked into small hydrocarbons and converted efficiently to aromatic hydrocarbons by catalytic pyrolysis over Al-MCM-41. The activity of catalytic conversion was enhanced by increasing the catalyst to reactant ratio.

AB - A rapid, sensitive and quantitative assay method for Hepatitis B surface antigen (HBsAg) is of paramount importance for the drug development and in the diagnosis of this disease. Here, we proposed a novel biosensor that sensitively and selectively screen Hepatitis B surface antigen. This strategy relies on the cross linking aggregation of gold nanoparticles (AuNPs) that were decorated with Hepatitis B surface antibody (HBsAb) and Raman reporter 5-thio-nitrobenzoic acid (TNB) by Hepatitis B surface antigen. The immune reaction between HBsAb and HBsAg offers this strategy high specificity, and the use of AuNPs additionally allows a visual and homogeneous assay format, thus permitting improved simplicity and throughput of the assays. The selectivity and sensitivity in HBsAg assay were achieved with a wide linear response range from 0.5 ng/mL to 50 ng/mL and a detection limit of 0.2 ng/mL. The results indicated that this strategy can offer a simple, robust and convenient platform for HBsAg analysis and related biochemical studies with high sensitivity and selectivity. PMID- 29448538 TI - One-Step RF-CVD Method for the Synthesis of Graphene Decorated with Metal and Metal Oxide Nanoparticles. AB - Bilayer and few layer-graphene (Gr) with noble metal (Ag and Au) and TiO2 nanoparticles were synthesized using atmospheric pressure radio frequency chemical vapor deposition (APRF-CVD). The precursors for the formation of the respective nanoparticles were dissolved in ethanol and injected into the APRF-CVD containing a Cu foil catalyst at 1000 degrees C. The graphene obtained had a blistered morphology similar to bubble-wrap. The bubble-like protrusions on the graphene sheet were caused by large nanoparticle clusters (~220 nm) formed below the graphene sheets. Smaller nanoparticles (10-80 nm) were also observed on top of the graphene sheets. Encapsulation of the nanoparticles with graphene, to yield core-shell particles was observed. Similarly, secondary growth of carbon nanotubes (CNTs) from the Au nanoparticles was observed. The average full width half maxima (FWHM) of 2D bands in the Raman spectra indicate that the graphene formed was predominantly bilayer graphene for Gr-TiO2 (55 +/- 1.72 cm-1), and few layer graphene for Gr-Ag (76 +/- 22 cm-1) and Gr-Au (88 +/- 4.7 cm-1). Raman spectroscopy also showed evidence for the doping of graphene and surface-enhanced Raman sensitivity (SERS) in the materials. These electronic properties of graphene with nanoparticles are relevant to various applications such as optoelectronics, catalysis, chemical and biological sensing.

AB - Developing an effective and reliable method for trace arsenic (As) detection is a prerequisite for improving the safety of drinking water. In this paper, we designed and prepared Ag@Fe3O4 core-shell nanoparticles (NPs), which were then used as Surface-Enhanced Raman Scattering (SERS) probe for trace arsenate (As(V)) detection. The Ag@Fe3O4 core-shell NPs were prepared by in situ growth of Fe3O4 NPs on the surface of AgNPs, which can effectively combine the strong adsorption ability of Fe3O4 nanoshells to As(V) with high SERS activity of Ag nanocores to decrease the detection limit. By use of Ag@Fe3O4 core-shell NPs for As(V) detection, the detection limit can be as low as 10 MUg/L, and a good linear relationship between the SERS intensity of As(V) and their concentrations in the range from 10 to 500 MUg/L was achieved. Furthermore, Ag@Fe3O4 core-shell NPs could be regenerated through desorption of As(V) from Fe3O4 nanoshells in NaOH solution, and then used for recyclic SERS detection. Therefore, it has been demonstrated for the first time that multifunctional Ag@Fe3O4 core-shell SERS probe could be applied to realize the highly sensitive and reversible detection of As(V).

The prepared films were characterised by various techniques such as XRD and FTIR. Amorphous nature and structural coordination of polymer electrolyte were confirmed by X-ray diffraction and Fourier transform infrared spectroscopy studies. The ionic conductivity of the prepared polymer electrolytes were analysed through ac impedance spectroscopy. The highest conductivity was found to be in the order of ~10-6 Scm-1 at an ambient temperature for the composition of 50PVA:50PVP:5 wt% MgCl2.

AB - The aim of this work was to prepare strong and conductive polyurethane acrylate nanocomposites. First, urethane prepolymers with different molecular weights and hydrophilicities were synthetized. Then, their corresponding polyurethane acrylate nanocomposites were prepared by ultrasonically-assisted emulsion polymerization in the presence of various ratios of urethane prepolymers and acrylate monomers. Thermogravimetric analysis (TGA) and tensile results showed that thermal stability and mechanical properties of polyurethane acrylate samples are significantly dependent on the molecular weight and hydrophilicity of the urethane prepolymer as well as the content of acrylate monomers. Polyurethane acrylate sample (i.e., PUAc-2B50) with optimum mechanical properties and thermal stability were chosen as matrix to prepare nanocomposites in the presence of nanotubes grafted with polymerizable acrylate groups (G-MWNTs). Transmission electron microscope (TEM) revealed that the surface of nanotubes is uniformly coated with polymer nanoparticles. The nanocomposites containing 3 wt% G-MWNTs demonstrated a great modulus up to 374 MPa and excellent strength up to 18.74 MPa. Meanwhile, they indicated remarkable high electrical and thermal conductivities; as the electrical conductivity of the nanocomposites increased by more than twelve orders of magnitude, and thermal conductivity reached to 12.5 times of the neat matrix. The developed nanocomposites hold high potential for diverse applications, such as printable electronic devices, nano-sensors, and heat/electrical induced shape memory polymers.

Pe6 nanophotosensitizer has small diameter less than 100 nm with spherical shape and core-shell structure. They were activated in aqueous solution while Ce6 was quenched due to its poor aqueous solubility. They showed no intrinsic cytotoxicity against normal cells and colon cancer cells.

AB - The objectives of this research were to study the microbial diversity of metal reducing bacteria enriched from sedimentary rock collected from a CO2 repository candidate site and to examine the effect that the bicarbonate concentration had on the iron reduction and biomineralization by the cultures. The enriched metal reducing bacteria (i.e., JG-3) consisted mostly of Exiguobacterium sp. and Shewanella sp., and the microbial reduction of akaganeite (beta-FeOOH), an Fe(III) oxyhydroxide, was examined over 7 days of bacterial cultivation at 30 degrees C under different concentrations of bicarbonate (0~210 mM). The akaganeite (beta-FeOOH) transformed into goethite (alpha-FeOOH) and magnetite (Fe3O4) in low HCO-3 buffered medium (<70 mM) and was transformed to magnetite and siderite (FeCO3) in high HCO-3 buffered medium (>140 mM). These results indicate that metal- reducing bacteria from a deep subsurface environment reduce and transform an iron oxyhydroxide to siderite (FeCO3) in HCO-3 buffered medium and that microbial iron reduction may accelerate the mineral trapping of CO2 for deep geologic sequestration.

AB - In this study, the nano-sized fume biogas production from food waste was investigated using lab scale semi-continuous stirred tank reactor (SCSTR) at 35 degrees C with 30d HRT and 30L working volume. The mesophilic digestion test was performed with three different feed materials (food waste) and food to microorganism (F/M) ratios (0.13, 0.34, and 0.27) in the same experiment. The results showed that the F/M ratios significantly affected the biogas production rate. The highest production rate was obtained at F/M ratio of 0.13. Nano-sized fume biogas produced in anaerobic digestion consists of 68.7% CH4, 31.2% CO2 and 30~200 nm particle. The average nano-sized fume biogas and methane production of digester were 29.96 L/Kg versus day-1 and 20.58 L/Kg versus day-1, respectively. The CH4 could be calculated as the heat energy 1.85 Kcal/Kg VS day-1. The digestion was operated without addition of chemicals or nutrients into the system.

AB - We have applied mechanical alloying (MA) to produce nanocrystalline Co2MnAl Heusler alloys using a mixture of elemental Co50Mn25Al25 powders. An optimal milling and heat treatment conditions to obtain a Co2MnAl Heusler phase with fine microstructure were investigated by X-ray diffraction, differential scanning calorimeter and vibrating sample magnetometer measurements. alpha-(Co, Mn, Al) FCC phases coupled with amorphous phase are obtained after 3 hours of MA without any evidence for the formation of Co2MnAl alloys. On the other hand, a Co2MnAl Heusler alloys can be obtained by the heat treatment of all MA samples up to 650 degrees C. X-ray diffraction result shows that the average grain size of Co2MnAl Heusler alloys prepared by MA for 5 h and heat treatment is in the range of 95 nm. The saturation magnetization of MA powders decreases with MA time due to the magnetic dilution by alloying with nonmagnetic Mn and Al elements. The magnetic hardening due to the reduction of the grain size with ball milling is also observed. However, the saturation magnetization of MA powders after heat treatment increases with MA time and reaches to a maximum value of 105 emu/g after 5 h of MA. It can be also seen that the coercivity of 5 h MA sample annealed at 650 degrees C is fairly low value of 25 Oe.

AB - In this study, the correlation between morphology and friction of manganese phosphate coating layer with additive agent of tartaric acid by 2, 4, 6 g were investigated. The microstructure and morphology of the coatings were studied by scanning electron microscopy (SEM), X-ray diffraction (XRD), energy-dispersive X ray spectroscopy (EDS) and atomic force microscopic (AFM). Potentiodynamic polarization test was carried out in order to evaluate the corrosion protection properties of manganese phosphate coating in 3.5 wt.% NaCl solution. Also, the tribology property of manganese phophate coating was tested by ball-on disk. In the results of EDS analysis, coating layer consists of elements such as Mn, P, Fe, O, and C. XRD showed that (Mn, Fe)5H2(PO4)4.4H2O in manganese phosphate coating layer was formed by the chemical reaction between manganese phosphate and elements in SM45C alloy. The corrosion resistance of manganese phosphate coating with additive agent was superior than the one without additive agent. Also, in the Fe amount in sludge, manganese phosphate coating layer with additive agent was observed to be considerably decreased.

AB - Conventional ion exchange beads are used for purification and demineralization of water and for various other applications in the chemical synthesis, hydrometallurgy, and agricultural industries. However, there are some disadvantages associated with ion exchange beads, such as distillation causing porosity during solvent removal, pre-swelling of beads to allow for core functionalization, and pre-swelling of beads overnight prior to end use. Fibrous ion exchange materials have advantages over the conventional ion exchange beads, including simplification of the overall preparation. In this study, a cation exchange fiber was prepared by a radiation-induced grafting method. Glycidyl methacrylate (GMA) was grafted onto cotton cellulose using a pre-irradiation method by electronbeam irradiation. Sequential treatment with sulfonic acid was performed to react with the cation pollutants. The degree of grafting increased up to 812% with the increase of absorbed dose, reaction time and monomer concentration. It was found that the sulfonation reaction occurred smoothly with 10% sodium sulfite solution, and a high 2.0 meq/g ion exchange capacity was obtained from 140% GMA-grafted non-woven cotton fabric. PMID- 29448552 TI - Plasmonic Screening Effect of Gold Nanoparticles Array on Light Absorption in Poly(3-hexyl)Thiophene Thin Film. AB - The localized surface plasmon (LSP) photophysical phenomenon occurring in metal nanostructures is often presented as a way to effectively couple light into sub wavelength-scale photovoltaic devices, which would otherwise suffer from a weak light absorption. The simultaneous complementary effect of localized optical field depletion receives far less attention. We studied a system consisting of a planar gold nanoparticles array (AuNP) deposited at the surface of a semiconducting polymer thin film (P3HT). By comparing the UV-vis spectra of P3HT with and without the AuNP array, we have estimated that the AuNPs screen the optical absorption in the interfacial layer of about 3.8 nm effective thickness due the near-field depletion effect. It suggests that the AuNP array may be used to practically "hide" a thin semiconductor layer, e.g., in order to tune the perceived color of the photovoltaic cell embedded in architecture, or in wearable devices.

AB - Bio-based polyamide 11 (PA11)-graphene nanocomposites with different filler concentrations (0.25, 0.5, 0.75, 1.5 and 3 wt%) were prepared by In Situ polymerization starting from a water dispersed suspension of graphene nanoplatelets. The effects of the incorporation of the filler were studied in terms of molecular, morphological, thermal and dynamic mechanical properties of the final materials. During the crystallization process from the melt, the filler induces a notable nucleating effect even if the crystal growth rate tends to decrease. The glass transition temperature tends to shift to higher temperatures indicating a decrement of the molecular mobility. Thermal stability is enhanced confirming a good filler dispersion into the matrix. Mechanical reinforcement, investigated by means of a dynamic mechanical thermal analyzer was also highlighted. It was observed that a graphene concentration of 0.75 wt% induces the highest final performances.

AB - Decoration with silver nanoparticles was obtained by coating graphene with a polydopamine layer, able to induce spontaneous metallic nanoparticles formation without any specific chemical interfacial modifier, neither using complex instrumentation. The choice of dopamine was inspired by the composition of adhesive proteins in mussels, related to their robust attach to solid surfaces. The synthesis procedure started from graphite and involved eco-friendly compounds, such as Vitamin C and glucose as reducing agent and water as reaction medium. Silver decorated graphene was inserted as secondary nanofiller in the formulation of a reference conductive adhesive based on epoxy resin and silver flakes. A wide characterization of the intermediate materials obtained along the step procedure for the adhesive preparation was carried out by several techniques. We have found that the presence of nanofiller yields, in addition to an improvement of the thermal conductivity (up to 7.6 W/m . K), a dramatic enhancement of the electrical conductivity of the adhesive. In particular, starting from 3 . 102 S/cm of the reference adhesive, we obtained a value of 4 . 104 S/cm at a nanofiller concentration of 11.5 wt%. The combined double filler conductivity was evaluated by Zallen's model. The effect of the temperature on the resistivity of the adhesive has been also studied.

AB - Cuprous oxide (Cu2O) is a kind of functional and promising energy material, which has been used as solar cells, adsorbents, and lithium ion battery electrode materials. And its mainly application is toward photocatalytic reactivity of organics' decomposition under visible light irradiation. However, the real role of Cu2O remains debated, for these reports don't give a powerful evidence to prove its significant photocatalytic properties. Here, we describe a one-pot synthesis method to construct Cu2O mesoporous spheres with large specific surface area at room temperature. This mesoporous microstructure is controlled through an Ostwald ripening-based dissolved partly process. And Cu2O mesoporous spheres are used to study the property of removing organic pollutants. We distinguish the real role of Cu2O by carefully measure the reduced portion of photocatalyst or adsorbent, while it is reacting with organic pollutants. At last, we find out the reason that has caused the concentration of organic pollutants to decrease is mainly based on the adsorption property of Cu2O, rather than its photocatalytic effect. However, the photocatalytic effect of Cu2O is very low under visible light irradiation.

AB - Tungsten carbide (WC) particles (~1 MUm) were dispersed in DI water and dropped onto conductive glass. The resulting WC films were used as dye-sensitized solar cell (DSSC) counter electrodes. The performance of the WC DSSC based on the organic thiolate/disulfide (T-/T2) electrolyte was ~0.78%. The cell efficiency was greatly improved after decorating palladium (Pd) or platinum (Pt) nanoparticles on WC particles with a promising efficiency of ~2.15% for Pd-WC DSSC and ~4.62% for Pt-WC DSSC. The efficiency improvement of the composited (Pd WC and Pt-WC) cells is attributed to co-functioning catalysts, the large electrode interfacial area and a low charge-transfer resistance at the electrolyte/counter electrode interface.

In addition, 5,6-O-(4-chlorophenyl)-L ascorbic acid (CPAA) exhibited strong free-radical scavenging activities in vitro against 2,2-diphenyl-1-picrylhydrazyl and superoxide anion. Therefore, CPAA should be investigated further as a worthy antioxidant. PMID- 29448561 TI - Electrical and Optical Properties of In2O3 Thin Films Deposited on Sapphire Substrate. AB - In2O3 thin films were prepared on c-plane sapphire substrates using laser molecular beam epitaxy technique. The X-ray diffraction (XRD) patterns revealed that the In2O3 thin films were highly oriented along the (111) direction. The intensity of (222) diffraction peaks mainly depend on growth temperature, and the crystallite sizes mainly depend on oxygen pressure. The carrier concentrations exhibit a decrease with increasing growth temperature and oxygen pressure, meantime, the resistivity increase. The red shift of In2O3 thin films respect to that of bulk In2O3 can be explained by defect energy levels formation, the blue shift of In2O3 thin films depends on carrier concentration, can be explained by Burstein-Moss band-filling effect. PMID- 29448562 TI - Microwave Absorption Properties of Uniform Ultra-Long SiC Nanowires. AB - The uniform ultra-long SiC nanowires (SiCNWs) were incorporated into the epoxy matrix to characterize the morphology effect on their electromagnetic wave absorption performance. The ultra-long SiCNWs with lengths of hundreds of micrometers were fabricated by chemical vapor deposition technique at 1250 degrees C, and have diameters of 10-60 nm with uniform morphologies. The microwave absorption performance of SiCNW/epoxy resin composites was investigated in the range of 8-18 GHz. Significant absorbing properties were discovered in the composites at frequencies of 8-12.4 GHz, comparing with a control sample. The slightest reflection loss (RL) value of -0.5 dB was obtained at 15 GHz at a very small SiCNWs concentration of 0.05 wt%. The significant absorbing properties of the uniform ultra-long SiCNWs at low frequencies can be mainly attributed to homogeneous small diameters to reduce the electromagnetic wave reflectance, high density interfacial polarization, complex conductive network structure and quantum effect.

AB - In this work, we present the fabrication and characterization of a 2-chloroethyl ethyl sulfide (2-CEES) gas sensor based on ZnO nanoparticles (NPs) synthesized by a hydrothermal method. We confirmed that synthesized ZnO NPs adopt a polycrystalline phase. Partially aggregated ZnO-NPs revealed spherical or ellipsoidal nanocrystalline particles in a size range of 30-50 nm, as observed by field-emission scanning electron microscopy (FE-SEM). The maximum response of the ZnO NPs was 15 at 1 ppm 2-CEES concentration, and a low detection limit of 0.4 ppm was observed at an optimal operating temperature of 250 degrees C. The lowest response time was 6 s in 20 ppm at 250 degrees C. The linearity response with correlation coefficient (R2) was 0.9887 at 2-CEE concentrations of 0.4-1 ppm at the operating temperature of 250 degrees C. The enhanced sensing performance and a decrease in the operating temperature were attributed to a high specific surface area and more active sites in the ZnO NPs after exposure to 2-CEES.

AB - Nanocrystalline zirconia with high surface area and pure tetragonal crystalline phase was prepared using ethylene diamine (EDA), which acts as both precipitating agent and dispersant of the zirconium precursor. The yttria stabilized zirconia (Y-TZP) is a very attractive material due to its excellent biocompatibility, high fracture toughness, high strength and low wear rates. So zirconyl chloride octahydrate (ZrOCl2 . 8H2O) and yttrium chloride hexahydrate (YCl3 . 6H2O) in different molar ratios were used as starting solution. The detailed effects of various process parameters such as reaction time, concentration of the precursor solution, amount of ethylene diamine, and calcination temperature on the structural properties of the zirconia powders were investigated. The preparation conditions significantly affected the structural stability, crystal size, and crystal phase of the final material. Increases in the reaction time and amount of ethylene diamine led to a substantial increase of the crystal growth rate, the specific surface area, and the tetragonal content of the zirconia. PMID- 29448566 TI - Highly Efficient Electrochemical Detection of Phenolic Compounds Utilizing Superior Catalytic Activity of Nanohybrids Consisting of Magnetic Nanoparticles and Gold Nanoclusters. AB - Although Fe3O4 magnetic nanoparticles (MNPs) have gathered particular interest as potent peroxidase mimetics, their practical utility has been critically limited by their low catalytic activity. Here, we have developed a nanohybrid material to significantly enhance the catalytic activity of MNPs by incorporating other enzyme mimetics, gold nanoclusters (AuNCs), through electrostatic attraction. Owing to the synergistic effect of MNPs and AuNCs, the constructed nanohybrid yielded highly enhanced peroxidase-like activity and higher resolution in electrochemical detection of H2O2 than bare MNPs. The nanohybrids were also successfully applied to detecting phenolic compounds including phenol and cresol, producing a concentration-dependent increase of cathodic current. Based on this result, we expect that the nanohybrids consisting of AuNCs and MNPs can serve as potent peroxidase mimetics for environmental monitoring.

AB - Performance and endurance of the Ru catalyst were studied for nitrous oxide monopropellant thruster system. The thermal decomposition of N2O requires a considerably high temperature, which make it difficult to be utilized as a thruster propellant, while the propellant decomposition temperature can be reduced by using the catalyst through the decomposition reaction with the propellant. However, the catalyst used for the thruster was frequently exposed to high temperature and high-pressure environment. Therefore, the state change of the catalyst according to the thruster operation was analyzed. Characterization of catalyst used in the operation condition of the thruster was performed using FE-SEM and EDS. As a result, performance degradation was occurred due to the volatilization of Ru catalyst and reduction of the specific surface area according to the phase change of Al2O3.

AB - The electrocatalytic stability of tin (Sn) nanoparticle for electrochemical reduction of CO2 to formate was measured using an H-type cell during electrolysis for 40 h. The Faradaic efficiency (FE) and partial current density (PCD) of formate formation reduced as much as 10% and 13% of the maximum values, respectively. To elucidate the decrease in FE and PCD, the changes in the morphology, chemical composition, the crystalline structure were investigated. The spherical Sn nanoparticles were pulverized after electrolysis. Furthermore, the crystal structure of the fresh Sn electrocatalyst was collapsed and changed into amorphous phase after 40 h electrolysis. The decrease in FE and PCD of formate production on the Sn/CFP electrode could be mainly originated from the reduction of the SnOx to Sn on the cathode surface during electrolysis.

An organic photovoltaic (OPV) cell was fabricated using the IZTO20 film deposited under the optimized condition as an anode electrode and the efficiency of up to 80% compared to that of a similar OPV cell using ITO film was observed. Reduction of surface roughness and electrical resistivity through annealing treatment was found to contribute to the improved efficiency of the OPV cell.

The deposited alloy nanowires are metastable fcc phase Co84.45Ni15.55 at -3.0 V and stable hcp phase Co80.75Ni19.25 at -1.6 V. The formation of the metastable fcc alloy nanowires can be attributed to smaller critical clusters formed at the high potential, as the smaller critical clusters favor fcc structure because of the significant surface energy effect. The content of Co inside nanowires increases with increasing potential. This can be understood by the polarization curves of depositing Co and Ni nanowires, which show that the current density ratio of Ni to Co at -1.6 V (0.88) is higher than that at -3.0 V (0.73).

AB - Self-assembled monolayers of thiols have been used to link a range of materials to planar gold surfaces or gold nanoparticles in nanoscience and nanotechnology. Novel mercapto silane systems are a promising alternative to dental noble metal alloys for enhanced resin bonding durability Goldbased alloys for full-cast restorations contain various base metal elements, which may bond to acidic functional monomers chemically, in addition to noble metal elements. This study examined how the additional incorporation of a phosphate monomer (di-2 hydroxyethyl methacryl hydrogenphosphate, DHP) into novel mercapto silane primer systems affected the resin bond strength to a type IV gold alloy pretreated with the primers. One of three commercial primers (Alloy Primer and M. L. Primer) and three experimental primer systems ((1) blend of gamma mercaptopropyltrimethoxysilane (SPS) and gamma-methacryloxypropyltrimethoxysilane (MPS) (both 1.0 wt%), (2) 1.0 wt% DHP-containing primer, and (3) blend of SPS, MPS, and DHP (each 1.0 wt%)) was applied to the alloy surfaces after sandblasting. Resin cylinders (diameter: 2.38 mm) were bonded to the surfaces and light-cured. All bonded specimens were stored in water at 37 degrees C for 24 h and then half of them additionally water immersed for 7 days (37 degrees C) and thermocycled 10,000 times before the shear bond strength test (n = 10). The mercapto silane systems (SPS + MPS) were found to show superior resin bonding durability to the commercial primers and the only DHP-containing primer, regardless of additional incorporation of the phosphate monomer.

AB - It is described that the arsenic (As) removal in real groundwater by filters in one-dimensional (1D) column (30 mm diameter * 240 mm height) using mixtures of heat treated yellow loess (YL) and sand is applied with consideration of water permeability. The effluent satisfies the concentration of <10 ppb drinking water regulation before As saturation with filters. Heat treated mixture of YL and sand under 4% H2/96% Ar condition result in higher As removal capacity than heat treated one under air atmosphere condition at 500 degrees C for 3 hours. It is due to more evolution of Fe3O4 phase in the mixture. In order to increase As removal efficiency significantly, alpha-Fe2O3 coated filters on mixture of YL and sand by hydrothermal treatment at 100 degrees C for 12 hours are utilized. It leads to highly enhanced As removal efficiency with little Fe ions leaching but half reduction of effluent rate, appealing as an alternative of practical As removal filters.

The functional group compositions and structures of the CQDs were investigated via Fourier transform infrared spectroscopy and X-ray powder diffraction. Based on these analyses, a linear relationship was obtained between the relative fluorescence intensity and concentration of Fe3+ within the range of 0 to 200 MUM (R2 = 0.9927). Fe3+ quenched the PL intensity of the CQDs more than other heavy metals, which indicates that CQDs can be used effectively as an Fe3+ sensing media.

AB - CdSe quantum dots (QDs) with a uniform size distribution were synthesized using a droplet-based microfluidic reactor. The droplet-based microfluidic reactor enabled continuous production of CdSe QDs at a temperature of less than 250 degrees C in an extremely shorter reaction time (less than 30 s) when compared with the batch reactor. The photoluminescence (PL) and ultraviolet (UV) absorption spectra of the CdSe QDs were recorded at different reaction times and the size and optical properties of the QDs were discussed. The structure morphology and elemental composition of the CdSe QDs were determined using a transmission electron microscopy (TEM) and electrondispersive spectroscopy (EDS). The size of CdSe QDs prepared using the microfluidic reactor was estimated to be from 1.6 to 2.6 nm with an average size of 2.2 nm. This droplet-based microfluidic reactor has the potential to be automated system continuous synthesis of CdSe QDs.

AB - We have synthesized a novel composite material, FeSb2 alloy with red phosphorus (P) dispersed in a conductive carbon matrix, using high-energy ball milling (HEBM). The introduction of red P into FeSb2 alloy led to a formation of Sb phase along with FeSb2 phase due to the difference of binding energy between the elements. The morphology and structure were analyzed by transmission electron microscopy (TEM) and X-ray diffraction (XRD). The active components (Sb and P) react with Li+ ions while inactive element (Fe) and carbon matrix act as a metal framework to support the electrochemically active Sb and as a buffer to reduce volume change during cycling, respectively. Among electrodes (FeSb2, FeSb2-P, FeSb2-P@C), the FeSb2-P@C electrode demonstrated high reversible capacity of 400 mAh g-1 with a good capacity retention of ~68% at 50 cycles and high rate reversible capacity of ~470 mAh g-1 at a current rate of 3000 mA g-1. PMID- 29448589 TI - Photocurrent Enhancement of CdSe Quantum-Dot Sensitized Solar Cells Incorporating Single-Walled Carbon Nanotubes. AB - We demonstrate quantum-dot sensitized solar cells (QDSSCs) which have colloidal CdSe quantum dots (TOPO-CdSe) as a sensitizer onto mesoporous TiO2 photoanodes. CdS quantum-dot (QD) layer plays a role of buffer layer for direct adsorption of TOPO-CdSe. We incorporate single-walled carbon nanotubes with TiO2 photoanode of our QDSSCs to facilitate efficient charge transfer. Shortcircuit current densities (Jsc) of our QDSSCs are enhanced while other parameters are maintained. Furthermore, we apply inert N2 pressure onto our sensitized photoanodes and observe 44% of Jsc enhancement with respect to pristine sample. Consequently, light-harvesting efficiency of our QDSSCs are increased. Significant series resistance reduction is observed from electrochemical impedance spectroscopy, indicating better interface contact between TiO2 photoanode and TOPOCdSe QD sensitizer are achieved.

AB - The catalytic pyrolysis of waste Korean pine nut shell (KPNS) over mesoporous Al2O3 was investigated by thermogravimetric analysis (TGA) and pyrolyzer-gas chromatography/mass spectrometry (Py-GC/MS). TGA results showed that the thermal and catalytic pyrolysis of KPNS over mesoporous Al2O3 has the same decomposition temperature. On the other hand, the maximum decomposition for the catalytic pyrolysis of KPNS over commercial-Al2O3 shifted to a higher temperature. The Py GC/MS results indicated that large amounts of oxygen-containing pyrolyzates, such as acids, furans, levoglucosan, and phenols, were produced by the non-catalytic pyrolysis of KPNS. These oxygen-containing pyrolyzates were upgraded efficiently into aromatic hydrocarbons by applying Al2O3 catalysts. Between the two Al2O3 catalysts, mesoporous Al2O3 showed better performance on the formation of aromatic hydrocarbons via the catalytic pyrolysis of KPNS than commercial Al2O3 because of its uniform larger pores.

AB - Hollow nanomaterials have attracted great interest because of their many applications in catalysis, nanoreactors, drug delivery systems, for lubrication and in gas sensors. Here, carbon sphere templates were prepared from glucose under hydrothermal conditions to facilitate the synthesis of hollow Fe2O3 nanospheres. Thermal decomposition of an iron precursor in benzylalcohol with the carbon spheres resulted in the deposition of Fe3O4 nanoparticles on the carbon sphere templates. The nanoparticles on the carbon surface naturally agglomerate and form a dense oxide shell during the calcination step, which produces typical Fe2O3 hollow structures. The gas sensing performance of the hollow Fe2O3 nanospheres was investigated at an operating temperature of 300 degrees C. The hollow Fe2O3 nanospheres showed high sensitivity (R = 10.766 at 1 ppm formaldehyde) with a linear response to formaldehyde gas concentration in the range of 0.8~2.4 ppm, and good selectivity to formaldehyde gas in volatile organic compounds, compared to commercial Fe2O3 nanoparticles. PMID- 29448592 TI - Comparative Study of Hydrogel-Based Recyclable Photocatalysts. AB - A series of hydrogen-based TiO2 photocatalysts were prepared by the simple entrapment of TiO2 nanoparticles in different hydrogel matrices using gelation processes. The hydrogels, namely, agarose, alginate, and chitosan, were used as matrices for TiO2 immobilization. Morphological differences were characterized for the three different hybrid gel photocatalysts. The rate of methylene blue (MB) photodegradation increased with increasing initial TiO2 dosage in all samples. The structural properties of the hydrogels significantly affected the diffusion of MB and altered the photocatalytic activities. Among these three different hybrid gel photocatalysts, the chitosan-based TiO2 membrane showed superior activity to the agarose- and alginate-based TiO2 hybrid gels. In addition, chitosan/TiO2 still showed excellent photocatalytic activity after being reused in three cycles, suggesting that chitosan/TiO2 is a new potential eco-friendly and a cost-effective photocatalyst for wastewater treatment.

AB - Surface finishing is as important as selection of material to achieve durability. Surface finishing is a process to provide surface with the desired performance and features by applying external forces such as thermal energy or stress. This study investigated the optimum supply current density for preventing from cavitation damages by applying to an anodizing technique that artificially forms on the surface an oxide coating that has excellent mechanical characteristics, such as hardness, wear resistance. Result of hardness test, the greater hardness was associated with greater brittleness, resulting in deleterious characteristics. Consequently, under conditions such as the electrolyte concentration of 10 vol.%, the processing time of 40 min, the electrolyte temperature of 10 degrees C, and the current density of 20 mA/cm2 were considered to be the optimum anodizing conditions for improvement of durability in seawater.

X-ray diffraction pattern results show that the PVA/CdS nanocomposite is hawleyite-sturcture and PVA/CdS:Cu nanocomposites show greenockite-hawelyite mixed structure. The sizes of CdS and CdS:Cu nanoparticles were estimated from transmission electron microscopy (TEM) images and are ~4 nm and ~10 nm respectively; which were formed inside the PVA polymer layer.

AB - Vanadium-doped rutile titania nanomaterial was synthesized by calcination of titania/vanadia composite thin gel films pre-coated natural cellulose substance (e.g., ordinary filter paper) at a relatively low temperature (600 degrees C). A better mixture of titanium and vanadium species is achieved during the layer-by layer (LbL) deposition process with cellulose nanofiber as a template, leading to more vanadium dopants incorporated in the titania crystal lattices. By sufficient vanadium-doping, the phase transformation temperature from anatase to rutile phase of titania is decreased effectively. The doping mode and existing state of vanadium in the titania nanomaterials and the effect on the anatase-to-rutile phase transformation have been studied. This strategy provides a facile and effective route to facilitate the phase transformation of various nanostructured metal oxides templated by natural cellulose substance through doping appropriate functional metal ions in the LbL deposition process. PMID- 29448596 TI - Enhanced Power Factor and Increased Conductivity of Aluminum Doped Zinc Oxide Thin Films for Thermoelectric Applications. AB - We report the structural, electrical and thermopower properties of un-doped and Al doped zinc oxide (ZnO) thin films. Al doping was carried out using 25 keV Al+ implantation with 0.1, 1 and 2% Al into ZnO. X-ray diffraction measurements showed that the lattice parameters were larger than the bulk values, which is consistent with the incorporation of Al atoms at interstitials. Al doping increased the electrical conductivity from 100 (Omegacm)-1 in the un-doped ZnO film to 598 (Omegacm)-1 in the 2% Al doped ZnO film. Electron doping by Al resulted in an increase in the carrier concentration and it had an advantageous effect on the mobility where it was highest for 2% doping. The absolute value of the Seebeck coefficient systematically increased for un-doped, 1% and 2% Al doped ZnO films where the room temperature values were -50.8, -60.9 and -66.3 MUV/K, respectively. The power factor increased significantly from 2.58 * 10-5 W/mK2 in un-doped ZnO film to 2.63 * 10-4 W/mK2 in 2% Al doped ZnO film. Our results suggest that the ion beam method is a suitable technique to enhance the thermoelectric properties of ZnO.

AB - Undoped and Mn2+ doped CoAl2O4 (MnxCo1-xAl2O4; x = 0.0 to 1.0) spinel nanoparticles were successfully synthesized by a microwave heating method using glycine as the fuel. X-ray powder diffraction (XRD) was confirmed the cubic spinel structure. The average crystallite size of the samples was found to be in the range of 16.46 nm to 20.25 nm calculated by Scherrer's formula. The nano sized particle-like morphology of the samples was confirmed by high resolution scanning electron microscopy (HR-SEM) and transmission electron microscopy (HR TEM) analysis. Energy dispersive X-ray (EDX) results showed the pure form of spinel aluminate structure. The band gap energy (Eg) of pure CoAl2O4 was estimated to be 3.68 eV from UV-Visible diffuse reflectance spectroscopy (DRS), and the Eg values increased with increase of Mn2+ ions, due to the smaller grain size. The magnetic hysteresis (M-H) loop showed the superparamagnetic nature, and the magnetization and coercivity values increased with increasing Mn2+ ions, which was confirmed by vibrating sample magnetometer (VSM). All compositions of the nano-catalysts were tested as catalyst successfully for the conversion of benzyl alcohol into benzaldehyde and observed good catalytic activity.

AB - ZSM-5/SBA-15 composite materials with different acidities and mesoporous system formations were successfully synthesized by three-step method. The catalysts were characterized by XRD, HR-TEM, BET, EDX and TPD-NH3 methods. It showed that the Si/Al molar ratio had effect on the formation and property of materials. Among synthesized catalysts with the different Si/Al molar ratios of 30 (HZSC-30), 50 (HZSC-50), 70 (HZSC-70), HZSC-50 catalyst had better mesoporous system formation and acidity. These properties helped this catalyst to have higher catalytic activity in 1,3,5-triisopropylbenzene cracking reaction than other studied catalysts in term of higher benzene product yield. In comparison to HZSM-5 microporous material that had the similar Si/Al molar ratio of 50, it showed that the formation of mesopore system of HZSC-50 catalyst had a major improvement on the cracking catalytic activity.

AB - The aim of this study was to determine the effect of hydroxyapatite (HA) coating on titanium dioxide (TiO2) nanotube by sol-gel process on viability of osteoblast like cell (MC3T3-E1) and bone formation in rat tibia. Specimens were divided into three groups including commercially pure titanium (control group), TiO2 nanotubes (group N), and HA coated TiO2 nanotubes (group HN). Surface characteristics were determined using field emission scanning electron microscope (FE-SEM; S-4700, Hitachi, Japan) and contact angles were measured. Cell viability was investigated in vitro after 1 day, 3 days, and 7 days of incubation. Implants (2.0 mm in diameter and 5.0 mm in length) were inserted into the tibia of rats. After 4 weeks, histomorphometric analysis was performed. Both N and HN groups showed enhanced hydrophilicity compared to control group. After 7 days of implantation, group HN showed higher cell viability with marginal significance (0.05 < P < 0.1). Bone to implant contact (BIC) ratio in the control group, group N, and group HN were 32.5%, 33.1%, and 43.8%, respectively.

AB - This study examined the microbial synthesis of magnetite and Pd/Zn-substituted magnetite using metal-reducing bacteria (Clostridium sp.), and the mineralogical characteristics of various types of magnetite formed initially and transformed minerals aged for 5 years. XRD, SXRD, and TEM-EDS analyses were used to characterize the mineralogy, crystal structure, chemistry, shape, and size distribution of the magnetites and transformed minerals. The metal-reducing bacteria reduced akaganeite and Pd/Zn-akaganeite to magnetite and Pd/Zn substituted magnetite using glucose as an electron donor, respectively. Metal substitution of Pd and Zn within the magnetite structure resulted in a decrease in the unit-cell parameter of the magnetite crystals. After 5 years, the biogenic magnetite showed changes in unit-cell parameters and transformation to siderite during prolonged cultivation under anaerobic conditions. These results indicate that long-term aging may affect the mineralogical transformation and alter the nano-sized crystal structure.

AB - Amyloid beta (Abeta) peptide is considered to be the critical causative factor in the pathogenesis of Alzheimer's disease (AD) because the hydrophilic molecules accumulated outside of the neural cells and results in the formation of highly toxicity amyloid plaque. In this study, we probed the interaction between Abeta and the antibody using atomic force microscopy (AFM). We compared two kinds of antibodies which are the antibody for Abeta 1-42 (antibody42) and the antibody for Abeta 1-16 (antibody16). To detect the interaction between Abeta and the antibodies, the single molecular force spectroscopy was carried out using Abeta modified glass substrate and the antibodies modified AFM probes. In the results, the single Abeta-antibody42 dissociation constant was estimated to be 5.2 * 10-3 s-1 and the single Abeta-antibody16 dissociation constant was 2.8*10-2 s-1. The Abeta-antibody42 showed 5.3 times longer bond life time compare with Abeta antibody16. It suggested that antibody42 is better choice for the Abeta sensor development.

AB - p-Xylene (PX) is an important large-volume commodity chemical in the petrochemical industry. Therefore, research on producing PX from bio-mass-derived resources is a considerable interest in relation to future alternative technologies. Recently, a new potential route for the direct and selective production of bio-based PX was reported, referred to as the Diels-Alder cycloaddition of biomassderived 2,5-dimethylfuran (DMF) and ethylene followed by the dehydration of an intermediate. Here, we prepared tungstated zirconia (WOx ZrO2) materials at different calcination temperatures and times as solid acid catalysts for PX production. From structural analyses and measurements of the surface acidity, the WOx-ZrO2 was found to be composed of mesopores with high surface acidity within the optimum calcination temperature and time range. This WOx-ZrO2 catalyst exhibited high catalytic activity upon the cycloaddition of DMF with ethylene as compared to commercial beta zeolite and previously reported silica-alumina catalysts.

Although Al-SBA-15 has weak acidity, the large molecular phenolic pyrolyzates of lignin were converted effectively into small molecular phenols and aromatic hydrocarbons due to the large pore size of Al-SBA-15. Compared to klason lignin, organosolv lignin produced larger amounts of valuable chemicals, such as mono-phenol, mono-aromatics, and furans, by catalytic pyrolysis over Al-SBA-15.

AB - Mesoporous CuCe-based ternary metal oxides were synthesized using KIT-6 as a hard template through a nano-casting method. The mesoporous CuCe-based metal oxides were applied to the catalytic decomposition of the ammonium dinitramide-based liquid monopropellant. The decomposition onset temperature over the meso-CuCe ternary metal oxides was much lower than that over the CuCeOx catalyst prepared by conventional precipitation method. Higher activity of the meso-CuCe ternary metal oxides is attributed to higher surface area and larger pore size of the meso-CuCe ternary metal oxides than those of the conventional CuCe oxide. The highest activity of meso-CuCeZr catalyst among the meso-CuCe ternary metal oxide catalysts is likely due to the highest mesoporosity.

AB - The purpose of this study was to evaluate the fitness of zirconia cores according to the amount and treated surface of glass infiltration. A maxillary right central incisor customized abutment was milled to have a 6 degrees slope and a 1 mm deep chamfer margin and was manufactured in an intaglio mold using silicone impression material. Fifty-six stone dies were produced by injecting high strength dental stone into a mold and then zirconia cores were milled with CAD/CAM systems. The control group (Control) used non glass-infiltrated zirconia, and the experiment group was divided by one with the glass and distilled water ratio of 1:300 and the other with the ratio of 1:100. Each group was divided into subgroups by glasstreated surface: external surface infiltration, internal surface infiltration, and both surface infiltration. The zirconia cores sintered after glass infiltration were attached to the stone dies and then cut. Afterwards, the absolute marginal discrepancies and internal gaps of the buccal and lingual sides were measured. The buccal absolute marginal discrepancies and lingual internal gaps were influenced by the glass infiltration amount (p < 0.05); while fitness of zirconia core were not affected by the glasstreated surface (p > 0.05). As a result of the above experiments, the glass-infiltrated zirconia cores showed a clinically acceptable fitness, which is within 120 MUm. This means that glass infiltration can be clinically used.

AB - Polydimethylsiloxane has exceptional fire retardancy characteristics, which make it a popular polymer in flame retardancy applications. Flame retardancy of polydimethylsiloxane with different nano fillers was studied. Polydimethylsiloxane composite fire property varies because of the shape, size, density, and chemical nature of nano fillers. In house made carbon and bismuth oxide nano fillers were used in polydimethylsiloxane composite. Carbon from biochar (carbonised bamboo) and a carbon by-product (carbon soot) were selected. For comparative study of nano fillers, standard commercial multiwall carbon nano tubes (functionalised, graphitised and pristine) as nano fillers were selected. Nano fillers in polydimethylsiloxane positively affects their fire retardant properties such as total smoke release, peak heat release rate, and time to ignition. Charring and surface ceramization are the main reasons for such improvement. Nano fillers in polydimethylsiloxane may affect the thermal mobility of polymer chains, which can directly affect the time to ignition. The study concludes that the addition of pristine multiwall carbon nano tubes and bismuth oxide nano particles as filler in polydimethylsiloxane composite improves the fire retardant property.

We optimized the procedure for bead preparation and validated the detection analysis by using LNCaP and DU-145 prostate cancer cell lysates. By applying the procedure, extracellular PSA from culture media of LNCaP cells and standard PSA proteins were quantified to assess whether the antibody-conjugated microsphere bead can be used to detect trace amounts of PSA. The PSA level results obtained by using the antibody-conjugated microsphere beads indicate that the procedure is sensitive and quantitative in analyzing PSA. Taken together, the results suggest that the method is suitable for microquantitation of PSA from patient specimens.

AB - The estrogenicity of octyl glucoside was studied with its preparation method using microporous zeolites. Its estrogenicity was estimated using E-assay method to confirm the possibility as non-endocrine disruptive surfactant. The octyl glucoside was synthesized from D-glucose with 1-octanol by direct glucosidation. The high conversion of D-glucose was obtained on H-FAU zeolite which has a mild acid strength. The conversion and yield were improved with increasing of acid site amount of the zeolite catalysts. The octyl glucopyranoside is more hydrophilic than nonylphenol and has a high wettability. The octyl glucosides represented extremely lower estrogenic cell proliferation compared with nonylphenol.

AB - The purpose of this study was to develop and evaluate a dry elixir (DE) system for enhancing the dissolution rate and oral bioavailability of celecoxib. DE system has been used for improving solubility, oral bioavailability of poorly water-soluble drugs. The encapsulated drugs or solubilized drugs in the matrix are rapidly dissolved due to the co-solvent effect, resting in both an enhanced dissolution and bioavailability. DEs containing celecoxib were prepared by spray drying method and characterized by morphology, drug/ethanol content, drug crystallinity, dissolution rate and oral bioavailability. The ethanol content and drug content in DE system could be easily altered by controlling the spraydrying conditions. The dissolution profile of celecoxib from DE proved to be much higher than that of celecoxib powder due to the nano-structured matrix, amorphous state and encapsulated ethanol. The bioavailability of celecoxib from DEs was compared with celecoxib powder alone and commercial product (Celebrex(r)) in rats. In particular, blood concentrations of celecoxib form DE formulation were much greater than those of native celecoxib and market product. The data demonstrate that the DE system could provide an useful solid dosage form to enhance the solubility, dissolution rate and oral bioavailability of celecoxib.

AB - Catalytic oxidation of toluene was carried out to investigate the effect of consecutive run on the catalytic property and performance of 1 wt.% Pt/gamma Al2O3 and the reduced 1 wt.% Pt/gamma-Al2O3. The properties were characterized by X-ray diffraction (XRD), the Brunauer Emmett Teller (BET) surface area, temperature programmed reduction (TPR), and transmission electron microscopy (TEM) analyses. In consecutive experiments the second catalytic run resulted in a significant increase of the toluene conversion compared to the first catalytic run, but the toluene conversion in the third catalytic run was similar to that of the second catalytic run. In addition, the reducing treatment of the catalyst led to an increase in the catalytic activity. The increasing catalytic activity in consecutive runs was dependent on the platinum particle size and the oxidation state of the platinum. The increase in platinum particle size during reaction and the reduction in the oxidation state of platinum by hydrogen pretreatment were responsible for the increase in the catalytic activity.

AB - The removal of acetaldehyde, which is one of main components of food waste odor was investigated using biomass char as a nanoporous carbon absorbent. The biomass char adsorbent obtained from the pyrolysis of Geodae-Uksae was modified by the water and KOH treatment. The modified char absorbent had a higher acetaldehyde removal efficiency than nanoporous CMK-8 possibly due to its high oxygen and nitrogen functional groups.

AB - Nanocrystalline vanadium nitride (VN) coatings for electrode materials for lithium battery with various deposition parameters have been prepared using dc and asymmetric bipolar pulsed dc magnetron sputtering. The deposition parameters such as pulse frequency and the duty cycle were varied from 0 to 50 kHz and 100 to 75%, respectively. Microstructural, crystallographic and electrical characterizations were performed by FE-SEM, AFM, XRD and 4-point probe method. With an increase in pulse frequency, coating microstructure evolved from a porous columnar structure to a highly dense one. Single- phase cubic (FCC) VN coatings with different preferential orientations were obtained as a function of pulse frequency. Minimum resistivity of 108 MUOmega-cm was obtained for the coatings deposited at pulse frequency of 25 kHz. PMID- 29448623 TI - Asymmetric Bipolar Pulsed dc Sputtered Niobium Nitride Films for Electrode Materials in Supercapacitors. AB - Niobium nitride (NbN) films were deposited using asymmetric-bipolar pulsed dc sputtering at different pulse parameters. Microstructural, electrical and mechanical characterizations were performed by FE-SEM, AFM, LCR meter and nanoindentator. The results show that pulse frequency has significant effects on coating's microstructure, structural and electrical properties of NbN films. With an increase in pulse frequency, coating microstructure evolved from a porous columnar structure to a highly dense one. Average crystal grain sizes of NbN films were decreased from 52.7 nm to 27.5 nm with an increase in pulse frequency. The minimum resistivity of 351 MUOmega-cm, the smoothest surface morphology with Ra roughness of 0.4 nm and the maximum hardness of 17.4 GPa were obtained for the films deposited at pulse frequency of 50 kHz, respectively.

AB - Silica nanoparticles with different aspect ratios (A.R.) were tested as reinforcing fillers of styrenebutadiene copolymer (s-SBR) for "green tyres," i.e., tires with lower rolling resistance. A commercial nanosilica with A.R. = 1 (Aerosil(r) 200) was compared with two nanosilica samples with A.R. = 2 and 4, synthesized by means of an innovative process, to ascertain if the filler shape was significant to improve the composite properties. In addition, bis triethoxysilylpropyltetrasulfide was grafted onto the particles surface, in order to obtain more hydrophobic materials and to enhance their dispersion in the elastomeric composites: pristine and modified silicas were then compared. Grafting extent was evaluated by thermogravimetric analysis. The surface properties of silicas were investigated by Fourier transform infrared spectroscopy and inverse gas chromatography. s-SBR/silica nanocomposites were then prepared and characterized assessing their dynamic-mechanical properties and carrying out morphological observations by transmission electron microscopy.

AB - A novel aptamers-based fluorescence resonance energy transfer (FRET) assay was developed employing the oppositely charged thioglycolic acid-capped CdTe quantum dots (TGA-CdTe QDs) and cysteamine-stabilized gold nanoparticles (cysteamine AuNPs). The fluorescence of TGA-CdTe QDs was significantly quenched with addition of cysteamine-AuNPs via the FRET. The FRET process can be modulated by 17beta estradiol in that the specific recognition between 17beta-estradiol and aptamers could show different effects on the aptamers-mediated aggregation of cysteamine AuNPs, and correspondingly adjust the FRET process. The feasibility of the method has been demonstrated by carrying out the detection of 17beta-estradiol with the wide linear range from 0.5.ng mL-1 to 150 ng.mL-1 and the low detection limit of 0.057 ng.mL-1. The established assay exhibited favorable selectivity towards 17beta-estradiol over other endocrine disrupting compounds and probably coexisting chemicals in real samples. Furthermore, the assay has been successfully applied to detect 17beta-estradiol in real tap water samples and feeds samples with good performance. The results were in full consistence with those from HPLC method, indicating the reliability of the detection system. The aptamers-based FRET assay is expected to offer a new opportunity for the rapid analysis of 17beta-estradiol in real samples.

AB - Natural proteins have been extensively studied as matrices for tissue engineering, due to their excellent biocompatibility and biological properties associated with increasing cell proliferation. By generating complex materials, cell and tissue functions can be tailored to obtain a specific direction, according to the medical needs. The aim of this paper was to obtain scaffolds based on collagen, hyaluronan and sericin, with morphology and physical-chemical properties adequate for controlled drug delivery systems. In this aim various tests were performed: in vitro swelling and degradation studies, Fourier Transform Infrared spectroscopy (FT-IR), Scanning Electronic Microscopy (SEM) and thermogravimetric analysis. Loading and releasing of ibuprofen is also discussed. The results indicate that scaffolds based on collagen, hyaluronan and sericin have a porous structure, strength and stability adequate for skin tissue engineering. The obtained scaffolds swell, degrade and have controlled drug release properties in simulated biological fluids.

AB - Nanoscale drug delivery systems have emerged as promising alternatives to overcome the problems associated with by conventional chemotherapy for cancer treatment such as poor drug stability and bio-distribution. Herein, we report a single walled carbon nanotubes (SWCNTs) based drug delivery system functionalized with polysaccharides such as alginate (ALG) and chitosan (CHI), which can be loaded with an anticancer drug curcumin (CUR). Modification of SWCNTs renders high drug loading efficiency and sustained drug release, imperative for drug activity. These were characterized through various tools viz, microscopic (transmission electron microscopy, scanning electron microscopy and atomic force microscopy) and zeta potential analysis. Incorporation of CUR inside the modified SWCNTs was studied through Fourier transform infrared spectroscopy, fluorescence and UV-visible spectroscopy. In vitro release studies were conducted to gain an insight into the pH-dependent release behavior of the entrapped CUR from modified SWCNTs. The anti-cancer potential was further demonstrated using human lung adenocarcinoma (A549) cells as a model system. Various cell culture based assays were performed to study the ability of released CUR from modified SWCNTs for inhibiting the cancer cell proliferation by inducing apoptosis. PMID- 29448628 TI - Functionalized Magnetic PLGA Nanospheres for Targeting and Bioimaging of Breast Cancer. AB - Superparamagnetic iron oxide nanoparticles (SPIONs) are actively used as highly sensitive imaging probes to provide contrast in MRI. In this study, we propose the use of SPIONs encapsulated with antibody-conjugated poly(lactic-co-glycolic acid) (PLGA) as a potent theragnostic agent. The SPIONs were synthesized by a chemical co-precipitation method of ferric and ferrous ions, and subsequently encapsulated with PLGA by using an emulsification-diffusion method. Herceptin was chemically conjugated to the SPION-encapsulating PLGA nanoparticles to target the human epidermal growth factor receptor 2 (Her2/neu) overexpressing breast cancers. FACS and MR molecular imaging revealed that the Her2/neu overexpressing cell line showed a stronger contrast enhancement than the Her2/neu non-expressing cell lines, and the signal intensity of in vivo MR imaging decreased as the concentration of Herceptin increased. This strategy of encapsulating SPIONs with PLGA will be highly useful in functionalizing magnetic nanoparticles and improving the diagnostic and therapeutic efficacy of a wide array of cancer treatments. PMID- 29448629 TI - Synthesis and Characterization of Calcium Phosphate Ceramic/(Poly(vinyl alcohol) Polycaprolactone) Bilayer Nanocomposites-A Bone Tissue Regeneration Scaffold. AB - beta Tricalcium phosphate ceramic was used to reinforce nanofibers in composite mats produced via electrospinning of poly(vinyl alcohol) (PVA), polycaprolactone (PCL) and (PVA: PCL) bilayers. The role of TCP ceramic on morphology of nanocomposites, crystalline structure, functional groups and thermal behaviour of nanocomposites were characterized by SEM, EDAX, XRD, FTIR and DSC analysis. Ultrathin cross-sections of the obtained nanocomposites were morphologically investigated with SEM and all fabricated composites consisted of fibers with average fiber diameter (AFD) around 100 nm except PCL-TCP fibers having AFD in the range of 608 nm. XRD profile presented the main peaks of beta-TCP (JCPDS 090169 and JCPDS 70-2065). The characteristic absorption bands of TCP were also identified by FTIR in all the composites. The thermal stability was enhanced after adding TCP filler particles in all the polymer composites. The porosity of PCL-TCP was found around 63% and (PVA-PCL: TCP) composite was found to be 58%. The biocompatibility of the (PVA-PCL: TCP) composite scaffold has also been investigated by culturing MG-63 osteoblast cells on it; primary results showed that the cells adhered and proliferated well on the composite scaffold. PMID- 29448630 TI - Dynamic and Depth Dependent Nanomechanical Properties of Dorsal Ruffles in Live Cells and Biopolymeric Hydrogels. AB - The nanomechanical properties of various biological and cellular surfaces are increasingly investigated with Scanning Probe Microscopy. Surface stiffness measurements are currently being used to define metastatic properties of various cancerous cell lines and other related biological tissues. Here we present a unique methodology to understand depth dependent nanomechanical variations in stiffness in biopolymers and live cells. In this study we have used A2780 and NIH3T3 cell lines and 0.5% and 1% Agarose to investigate depth dependent stiffness and porosity on nanomechanical properties in different biological systems. This analytical methodology can circumvent the issue associated with the contribution of substrates on cell stiffness. Here we demonstrate that by calculating 'continuous-step-wise-modulus' on force versus distance curves one can observe minute variation as function of depth. Due to the presence of different kinds of cytoskeletal filament, dissipation of contact force might vary from one portion of a cell to another. On NIH3T3 cell lines, stiffness profile of Circular Dorsal Ruffles could be observed in form of large parabolic feature with changes in stiffness at different depth. In biopolymers like agarose, depending upon the extent of polymerization in there can be increase or decrease in stiffness due variations in pore size and extent to which crosslinking is taking place at different depths. 0.5% agarose showed gradual decrease in stiffness whereas with 1% agarose there was slight increase in stiffness as one indents deeper into its surface. PMID- 29448631 TI - Effects of CdSe and CdSe/ZnS Core/Shell Quantum Dots on Singlet Oxygen Production and Cell Toxicity. AB - Four types of quantum dots (QDs) with varying emission wavelengths were synthesized in this study. The dots included CdSe and CdSe/ZnS core/shell QDs with short emission wavelengths of 540 nm and 560 nm, respectively, as well as CdSe and CdSe/ZnS core/shell QDs with longer emission wavelengths of 585 nm and 595 nm, respectively. The ligands on the QD surfaces were exchanged with mercaptopropionic acid (MPA) to make them water-soluble. The efficiency of singlet oxygen (1O2) production from both CdSe and CdSe/ZnS core/shell QDs was highest at a QD concentration of 14 MUg/ml Singlet oxygen production from the CdSe QDs was higher than that with the CdSe/ZnS core/shell QDs after 1 h of LED470 irradiation. However, the singlet oxygen production of CdSe/ZnS core/shell QDs was much higher than that of CdSe QDs at concentrations above 14 MUg/ml. The cytotoxicities of both CdSe and CdSe/ZnS core/shell QDs were investigated using HeLa cells. PMID- 29448632 TI - MPEG-CS/Bmi-1RNAi Nanoparticles Synthesis and Its Targeted Inhibition Effect on CD133+ Laryngeal Stem Cells. AB - Previous studies have confirmed that CD133+ cells in laryngeal tumor tissue have the characteristics of cancer stem cells. Bmi-1 gene expression is central to the tumorigenicity of CD133+ cells. In this study, we tried to develop a new siRNA carrier system using chitosan-methoxypolyethylene nanoparticles (CS-mPEG-NPs) that exhibit higher tumor-targeting ability and enhanced gene silencing efficacy in CD133+ tumor stem cells. It is hoped to block the self-renewal and kill the stem cells of laryngeal carcinoma. The mPEG-CS-Bmi-1RNAi-NPs were synthesized and their characters were checked. The changes in invasion ability and sensitivity to radiotherapy and chemotherapy of CD133+Hep-2 tumor cells were observed after Bmi 1 gene silencing. The mPEG-CS-Bmi-1RNAi-NPs synthesized in this experiment have a regular spherical form, a mean size of 139.70 +/-6.40 nm, an encapsulation efficiency of 85.21 +/- 1.94%, with drug loading capacity of 18.47 +/- 1.83%, as well as low cytotoxicity, providing good protection to the loaded gene, strong resistance to nuclease degradation and high gene transfection efficiency. After Bmi-1 gene silencing, the invasion ability of CD133+ cells was weakened. Co cultured with paclitaxel, the survival rates of CD133+Bmi-1RNAi cells were lower. After radiotherapy, the mean growth inhibition rate of CD133+/Bmi-1RNAi cells was significantly lower than CD133+ cells. In conclusion, the mPEG-CS nano-carrier is an ideal vector in gene therapy, while silencing the Bmi-1 gene can enhance the sensitivity of CD133+ tumor stem cells to chemoradiotherapy and abate their invasion ability. PMID- 29448633 TI - Copolymeric Micelles Loading Curcumin: Preparation, Characterization and In Vitro Evaluation. AB - Curcumin (Cur) has potent antitumor activity; however, its clinical use is limited due to its hydrophobicity and instability at physiological pH. In this work, Cur was incorporated into MPEG2K-P(CL-co-LLA) micelles to form the Cur loaded micelles with drug loadings from 4.72% to 35.21% depending on the ratios of drug to MPEG2K-P(CL-co-LLA). The resulting Cur-loaded micelles were spherical with mean hydrodynamic diameters in the range of 28.8 to 58.6 nm, having excellent water-solubility and good stability at pH 7.4. The freeze-drying powders of the Cur-loaded micelles were easily rehydrated. It was found that Cur was slowly released from the micelles with a cumulative drug release percentage of 78.11% within 14 days and there was no obvious drug burst release. MTT tests showed that, the IC50 values of the Cur-loaded micelles were lower than those of free Cur against cancer cells (MDA-MB-231 cells and 4T1 cells). No matter for cancer cells (MDA-MB-231 cells and 4T1 cells) or healthy cells (L929 cells), cell viabilities were all >90% after incubating with the blank MPEG2K-P(CL-co-LLA) micelles, even at very high micelle concentration (up to 1000 MUg/mL), indicating the blank micelles were of no or extremely low cytotoxicity per se. The Cur loaded micelles were taken up mainly via endocytosis route and the cellular uptake on 4T1 cells increased with incubation time. They could induce more cell apoptosis compared to free Cur. These results suggested that curcumin-loaded MPEG2K-P(CL-co-LLA) micelles may be a potential nanoscale drug delivery system for cancer therapy. PMID- 29448634 TI - Comparison of the Off-Target Effects Among One-Base to Three-Base Mismatched Targets of gRNA Using a Blue to White Assay. AB - The present study was designed to test a new strategy for comparing the off target effects of CRISPR/cas9 employing a blue/white colony based assay. Eight types of AmpR plasmids with matched, one base mismatched, two bases mismatched and three bases mismatched targets were constructed. The wild typed alpha peptide of the beta-glactosidase gene and some with mutations, chosen as the targets, were successfully subcloned into the plasmids in an inframe pattern. The relevant gRNA and cas9 were subcloned into the ChloR plasmid. Transformation of the plasmid harboring the target gene yielded blue colonies, while white colonies formed in the plates following the co-transformation of target gene plasmid and the CRISPR/cas9 plasmid. Colonies in different levels of blue color were formed from the plasmids having completely matched target and mismatched targets. The appearance of different blue levels following the co-transformation of the different target plasmid and CRISPR/cas9 plasmid qualitatively indicated the effectiveness of the gRNA, while the ratio of the AMP/CL colonies can be used for relatively quantitative evaluation. The target and off-target effects among different targets of gRNA were differentially identifiable and these effects in turn demonstrated the effectiveness of the blue to white assay. Either the qualitative or the quantitative analysis of the blue to white depends on the final interactions among the target, the cas9 and the gRNA. Clearly, when co transformation is replaced by single transformation using a specialized nanoparticle containing these three components, the target and off-target effect will be more accurately evaluated. Thus, this study provided a model for application of nanoparticle in gene editing studies. PMID- 29448635 TI - Surface Plasmon Resonance Aptamer Biosensor for Discriminating Pathogenic Bacteria Vibrio parahaemolyticus. AB - In this paper, whole-bacteria SELEX (WB-SELEX) strategy was adopted to isolate specific aptamers against Vibrio parahaemolyticus. Round selection for V. parahaemolyticus was conducted 11 rounds, including two negative selection rounds. It was determined through real-time PCR amplification and post-SELEX experiment. The selected aptmers had high binding property and specificity to V. parahaemolyticus. Of 28 aptamers tested, VPCA-apta#1 had the highest binding affinity compared to other aptamer candidates obtained. To detect V. parahaemolyticus, aptamer based SPR biosensor platform was constructed and pathogenic bacteria sensing was conducted in two steps. The first step was to construct 5'-biotinylated VPCA-apta#1 binding probe. The second step was to incubate V. parahaemolyticus and test microbes in functionalized SA sensor chip in parallel. Our platform showed significant activity for detecting and discriminating V. parahaemolyticus from other enteric species such as Escherichia coli, Listeria monocytogenes, Sigella sonnei, and Vibrio fischeri. This is the first report on the use of whole-SELEX to isolate DNA aptamers specific for V. parahaemolyticus. We demonstrated the feasibility of using aptamer platform for the detection of V. parahaemolyticus in various food supplies. It might be used in multiple points of care for diagnosing Vibriosis.

AB - Polydopamine (PDA) film coatings are multifunctional substances because these coatings can adhere to nearly all known solid materials. The self-polymerization of dopamine in aqueous solution was investigated in this study; PDA films are an effective platform for further functionalization similar to the reduction of silver ions into silver nanoparticles (NPs).

PMID- 29448638 TI - Delivery of Abscisic Acid to Plants Using Glutathione Responsive Mesoporous Silica Nanoparticles. AB - An intracellular glutathione (GSH) responsive phytochemical delivery system based on thiol gated mesoporous silica nanoparticles (MSNs) was developed and tested on the model plant Arabidopsis thaliana. In the present study, monodispersed MSNs with particle diameters of ~20 nm and pore sizes of ~2.87 nm were synthesized and modified. Abscisic acid (ABA), a key phytohormone, was entrapped in the mesopores of MSNs and then the pore entrances of MSNs were covered with decanethiol gatekeepers through GSH-cleavable disulfide linkages. An in vitro release test of ABA from decanethiol gated MSNs proved that there was efficient loading and entrapment of phytochemicals in the absence of a GSH redox trigger. Most importantly, in planta experiments demonstrated that GSH-mediated release of ABA from the pores of MSNs significantly reduced the leaf stomatal aperture and inhibited water loss of treated plants. Moreover, compared with the usage of free ABA, the controlled release of the encapsulated phytohormone from MSNs markedly prolonged the expression of the ABA inducible marker gene (AtGALK2) and finally, improved the drought resistance ability of Arabidopsis seedlings under drought stress. Therefore, the concept of using short-chain molecules as gatekeepers to encapsulate biomolecules in MSNs was demonstrated. The application of MSNs with redox-responsive gatekeepers has been shown in this study to be a potential and efficient technique to deliver phytochemicals into plants and release them in a controllable fashion. PMID- 29448637 TI - Characteristics of Sodium Polyacrylate/Nano-Sized Carbon Hydrogel for Biomedical Patch. AB - Conductive hydrogels were prepared for biomedical patch in order to improve the electrical conductivity. Sodium polyacrylate and nano-sized carbon were mixed and fabricated by aqueous solution gelation process in various contents of nano-sized carbon with 0.1, 0.5, 1.0 and 2.0 wt%. Sodium polyacrylate/nano-sized carbon conductive hydrogels were investigated by molecular structure, surface morphology and electrical conductivity. The conductivity of the hydrogel/nano-sized carbon conductive hydrogel proved to be 10% higher than conductive hydrogel without nano sized carbon. However, it was founded that conductive hydrogels with nano-sized carbon content from 0.5 up to 2.0 wt% were remarkably decreased. This may be due to the non-uniform distribution of nano-sized carbon, resulting from agglomerates of nano-sized carbon. The developed hydrogel is intended for use in the medical and cosmetic fields that is applicable to supply micro-current from device to human body. PMID- 29448639 TI - Temperature Dependent Electron Transport Properties of Gold Nanoparticles and Composites: Scanning Tunneling Spectroscopy Investigations. AB - Scanning tunneling spectroscopy (STS) is used for investigating variations in electronic properties of gold nanoparticles (AuNPs) and its composite with urethane-methacrylate comb polymer (UMCP) as function of temperature. Films are prepared by drop casting AuNPs and UMCP in desired manner on silicon substrates. Samples are further analyzed for morphology under scanning electron microscopy (SEM) and atomic force microscopy (AFM). STS measurements performed in temperature range of 33 degrees C to 142 degrees C show systematic variation in current versus voltage (I-V) curves, exhibiting semiconducting to metallic transition/Schottky behavior for different samples, depending upon preparation method and as function of temperature. During current versus time (I-t) measurement for AuNPs, random telegraphic noise is observed at room temperature. Random switching of tunneling current between two discrete levels is observed for this sample. Power spectra derived from I-t show 1/f2 dependence. Statistical analysis of fluctuations shows exponential behavior with time width tau ~ 7 ms. Local density of states (LDOS) plots derived from I-V curves of each sample show systematic shift in valance/conduction band edge towards/away from Fermi level, with respect to increase in temperature. Schottky emission is best fitted electron emission mechanism for all samples over certain range of bias voltage. Schottky plots are used to calculate barrier heights and temperature dependent measurements helped in measuring activation energies for electron transport in all samples. PMID- 29448640 TI - Impact of Isolation and Immobilization Layers on the Electro-Mechanical Response of Piezoresistive Nano Cantilever Sensors. AB - In the last decade, piezoresistive nano cantilever sensors have been extensively explored, especially for chemical and biological sensing applications. Piezoresistive cantilever sensors are multi-layer structures with different constituent materials. Performance of such sensors is a function of their geometry and constituent materials. For a fixed material set, the pre-requisite for optimizing the performance of a composite piezoresistive cantilever sensor is careful geometrical design of its constituent layers. Even though, treatise encompasses various designs of such sensors, typically for computational simplicity the functional layers i.e., the isolation and immobilization layers are neglected in the modeling stages. In this paper, we elucidate the impact of the functional layers on the electro-mechanical response of composite piezoresistive nano cantilever sensors. Systematic and detailed computations are performed using theoretical models and numerical simulations. Results show that both the isolation and immobilization layers play a critical role in governing the sensor performance. Simulation results depict that compared to a sensor with an isolation layer of thickness 100 nm, a sensor without isolation layer has 36.29% and 42.51% better deflection sensitivity and electrical sensitivity respectively. Furthermore, it is found that when an immobilization layer of thickness 40 nm is added atop the isolation layer, the deflection sensitivity and electrical sensitivity reduces by 12.98% and 15.83% respectively. Through our investigation it is shown that the isolation and immobilization layers not only play a vital role in determining the stability and electro-mechanical response of the sensor but their negligence in the design stages can be detrimental. Apart from investigating the impact of the immobilization layer thickness, to model the sensor closer to real time operational conditions, we have performed analysis to understand the impact of non-uniformity in the immobilization layer thickness and non-uniform surface stress loading on the electro-mechanical response of the sensor. Results and inferences obtained from this study will help NEMS engineers to optimize the performance of piezoresistive nano cantilever sensors and to design multi-layer cantilever platform structures for other transducers.

AB - The lateral structure of the p-i-n diode was characterized for thin-film silicon solar cell application. The structure can benefit from a wide intrinsic layer, which can improve efficiency without increasing cell thickness. Compared with conventional thin-film p-i-n cells, the p-i-n diode lateral structure exploited direct light irradiation on the absorber layer, one-side contact, and bifacial irradiation. Considering the effect of different carrier lifetimes and recombinations, we calculated efficiency parameters by using a commercially available simulation program as a function of intrinsic layer width, as well as the distance between p/i or n/i junctions to contacts. We then obtained excellent parameter values of 706.52 mV open-circuit voltage, 24.16 mA/Cm2 short-circuit current, 82.66% fill factor, and 14.11% efficiency from a lateral cell (thickness = 3 MUm; intrinsic layer width = 53 MUm) in monofacial irradiation mode (i.e., only sunlight from the front side was considered). Simulation results of the cell without using rear-side reflector in bifacial irradiation mode showed 11.26% front and 9.72% rear efficiencies. Our findings confirmed that the laterally structured p-i-n cell can be a potentially powerful means for producing highly efficient, thin-film silicon solar cells.

Silica nanoparticles could be incorporated well uniformly in the completely miscible system, which can form a three-dimensional network structure to achieve the enhancement of mechanical properties as well as the additional reduction of methanol permeability.

PMID- 29448643 TI - Effect of Colloidal Medium on the Shelf-Life and Stability of Gold Nanorods Prepared by Seed-Mediated Synthesis. AB - Gold nanorods (GNRs) owing to their tunable longitudinal surface plasmon resonance in tissue transparent near infrared region have potential applications (like cancer imaging, surface enhanced Raman spectroscopy, cancer targeting, drug delivery and optical hyperthermia) in nanomedicine. Success of these diagnosis/therapy options depends on the plasmonic properties of gold nanorods, which are influenced by the interaction of GNRs with the colloidal medium. In this article, a systematic study is performed to evaluate the effect of colloidal medium on shelf life and stability of gold GNRs. As-synthesized GNRs are preserved in four aqueous media (deionized water, pluronic F-127, CTAB solution and growth solution) and their stability is investigated by closely monitoring the changes in the plasmonic signatures by UV-Visible spectroscopy and variation in hydrodynamic size by photon correlation spectroscopy for 30 days. As synthesized GNRs are most stable in deionized water followed by pluronic F-127, CTAB and growth solution. The vast difference in the colloidal stability of GNRs in different media is due to the differences in surface driven unzipping of gold in these aqueous media.

AB - Metal ions (Cr, Ni, Co) doped titania (M-TiO2) coupled with the long after glow phosphor MgAl2O4:(Pr3+, Dy3+) particles were synthesized by the sol-gel method, with the best mass ratio of MgAl2O4:(Pr3+, Dy3+) to M-TiO2 as 4:6. MgAl2O4:(Pr3+, Dy3+)/M-TiO2 had the persistent methyl orange (MO) photocatalytic degradation ability and the photocatalytic degradation went on reacting more than 90 min in dark after turning off the light. MgAl2O4:(Pr3+, Dy3+) emitted the light as a light source in dark which was absorbed by M-TiO2. The differences of MgAl2O4:(Pr3+, Dy3+)/Cr-TiO2, MgAl2O4:(Pr3+, Dy3+)/Ni-TiO2 and MgAl2O4:(Pr3+, Dy3+)/Co-TiO2 might be attributed to the difference in the metal ions doping. The composite MgAl2O4:(Pr3+, Dy3+)/Cr-TiO2 revealed the highest ability of persistent photocatalytic degradation methyl orange. Different metal ions doping made the TiO2 with different band gap.

AB - The presence of secondary phases is one of the main issues that hinder the growth of pure kesterite Cu2ZnSnS4 (CZTS) based thin films with suitable electronic and junction properties for efficient solar cell devices. In this work, CZTS thin films with varied Zn and Sn content have been prepared by RF-power controlled co sputtering deposition using Cu, ZnS and SnS targets and a subsequent sulphurization step. Detailed TEM investigations show that the film shows a layered structure with the majority of the top layer being the kesterite phase. Depending on the initial thin film composition, either about ~1 MUm Cu-rich and Zn-poor kesterite or stoichiometric CZTS is formed as top layer. X-ray diffraction, Raman spectroscopy and transmission electron microscopy reveal the presence of Cu2-xS, ZnS and SnO2 minor secondary phases in the form of nanoinclusions or nanoparticles or intermediate layers.

AB - The CuS/RGO composites were prepared using a facile one-step solvothermal method. The asobtained samples were characterized by X-ray diffraction (XRD), Raman spectra, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), Brunner-Emmet-Teller (BET) measurements and UV-Vis spectrophotometry. The results showed that the CuS particles were uniformly dispersed on the surface of RGO and electronic migration effect existed between RGO and CuS. The photocatalytic activity of CuS/RGO composites was evaluated by the degradation of Cationic blue SD-BL, Cationic red X-5GN, Direct blue 86, Reactive blue KN-R, Methylene blue and Rhodamine B under visible light irradiation. The photocatalytic experiments showed that the CuS/RGO composites exhibited a better photocatalytic performance for organic dyes with absence of hydrogen peroxide (H2O2) due to the inhibition of recombination of electron-hole pair induced on the surface of CuS. The photodegradation ratio of Cationic blue SD-BL, Cationic red X-5GN, Direct blue 86, Reactive blue KN-R, Methylene blue and Rhodamine B increased to 100%, 95.8%, 99.5%, 87.8%, 100%, 81% after 75 min of irradiation, respectively. Moreover, no significant decline of CuS/RGO photocatalyst for photodegradation of dyes was observed after five cycles, indicating better photostability of the samples. Thus, the CuS/RGO composites could have a promising application in wastewater treatment.

AB - The demand of crack tip opening displacement (CTOD) test which evaluates fracture toughness of a cracked material is very important to ensure the stability of structure under severe service environment. The validity of the CTOD test result is judged using several criterions of the specification standards. One of them is the artificially generated fatigue pre-crack length inside the specimen. For acceptable CTOD test results, fatigue pre-crack must have a reasonable sharp crack front. The propagation of fatigue crack started from the tip of the machined notch, which might have propagated irregularly due to residual stress field. To overcome this problem, test codes suggest local compression method, reversed bending method and stepwise high-R ratio method to reduce the disparity of residual stress distribution inside the specimen. In this paper, the relation between the degree of local compression and distribution of welding residual stress has been analyzed by finite element analyses in order to determine the amount of effective local compression of the test piece. Analysis results show that initial welding residual stress is dramatically varied three-dimensionally while cutting, notch machining and local compressing due to the change of internal restraint force. From the simulation result, the authors find that there is an optimum amount of local compression to modify regularly for generating fatigue pre-crack propagation. In the case of 0.5% compressions of the model width is the most effective for uniforming residual stress distribution.

AB - Glutathione (GSH), a thiol-containing tripeptide, has a pivotal role in maintaining the normally physiological environment in biology. Here, we report a novel self-assembly fluorescence resonance energy transfer (FRET) sensing platform for GSH detection by using the environment-friendly Cu:Zn-In-S/ZnS quantum dots (QDs) and MnO2 nanosheets. In this assay, fluorescence of Cu:Zn- In S/ZnS QDs could be quenched by MnO2 nanosheets based on FRET. Upon the addition of GSH, MnO2 nanosheets were reduced into Mn2+ ions because of the rapid redox reaction, and consequently the fluorescence of QDs was recovered. A good linear relationship was obtained from 1 to 20 MUM for the detection of GSH with a low detection limit of 500 nM. Meanwhile, the sensing system also exhibited high selectivity against other electrolytes and biomolecules. Moreover, the satisfactory results in the determination of GSH in serum samples indicate that the assay holds great potential for detecting GSH in biological fluids. This method shows many advantages including high sensitivity, short assay time, good simplicity as well as label-free and environmental friendly, which is expected to facilitate the GSH quantification relating to biological and biomedical studies.

AB - This study presents the forced convective heat transfer of a nanofluid consisting of distilled water and different weight concentrations (1 wt% and 2 wt%) of Al2O3 nanoparticles flowing in a vertical shell and tube heat exchanger under counter flow and laminar flow regime with certain constant heat flaxes (at 20 degrees C, 30 degrees C, 40 degrees C and 50 degrees C). The Al2O3 nanoparticles of about 50 nm diameter are used in the present study. Stability of aqueous Al2O3 nanofluids, TEM, thermal conductivity, temperature differences, heat transfer rate, T-Q diagrams, LMTD and convective heat transfer coefficient are investigated experimentally. Experimental results emphasize the substantial enhancement of heat transfer due to the Al2O3 nanoparticles presence in the nanofluid. Heat transfer rate for distilled water and aqueous nanofluids are calculated after getting an efficient setup which shows 19.25% and 35.82% enhancement of heat transfer rate of 1 wt% and 2 wt% aqueous Al2O3 nanofluids as compared to that of distilled water. Finally, the analysis shows that though there are 27.33% and 59.08% enhancement of 1 wt% Al2O3 and 2 wt% Al2O3 respectively as compared to that of distilled water at 30 degrees C, convective heat transfer coefficient decreases with increasing heat flux of heated fluid in this experimental setup.

AB - ACF/GO/PEI (activated carbon fiber/graphene oxide/polyethyleneimine) composite was fabricated by crosslinking reaction and characterized with Scanning electron microscope (SEM), N2 physical adsorption and Fourier transform infrared spectroscopy (FTIR). Furthermore, the adsorption behavior of ACF/GO/PEI composite for methyl orange (MO) from aqueous solution was investigated. The experimental results showed that the specific surface area of ACF/GO/PEI composite is 1013.6 m2/g and almost the same as that of original ACFs. However, with a larger fraction of mesopores, the pore structure of ACF/GO/PEI composite showed a significant change in comparison with that of original ACFs. Accordingly, ACF/GO/PEI composite indicated more excellent adsorptivity than ACFs. The tests also showed the adsorption capacity decreased with the increase in adsorbent mass and pH. The adsorption isotherm was fitted using both Langmuir and Freundlich adsorption models and the adsorption process was found to be well-described by Langmuir model. Moreover, the adsorption kinetics was discussed with pseudo-first order, pseudo-second-order and intra-particle diffusion models and the results disclosed the kinetic data were well fitted with pseudo-second-order kinetic model and the adsorption rate was controlled by intra-particle diffusion and film diffusion. Thermodynamic parameters including DeltaG, DeltaH and DeltaS showed that the adsorption process was a spontaneous, endothermic and increasing randomness process.

AB - The tuneability of oxygen containing groups in graphene oxide (GO) that controls physicochemical properties is highly desirable for device applications. In this context, the thermally reduced graphene oxide (r-GO) powders and spin coated thin films with varying sp2/sp3 carbon network have been prepared using highly exfoliated GO (synthesized using modified Hummer's method with an innovative conjunction of lyophilisation). The additional step of lyophilisation results in the formation of highly exfoliated and monodispersed GO nanosheets as evidenced from FESEM, TEM, XRD, and Raman, FT-IR and UV-Vis spectroscopy. Spectroscopic analysis revealed the systematic evolution of r-GO with tuneable structural, optical and electrical properties as results of varying annealing temperatures (100-400 degrees C), due to restoration of sp2 conducting carbon network i.e., the formation of new -C?C- network and Stones-Wales defect. The tuneability of physical properties is further corroborated by change in the resistance values, as evidenced through the current-voltage characteristics in GO thin film based lateral device structures with Ag and Al top contacts. Controlling physicochemical properties at relatively low processing temperature warrants the utilization of GO and r-GO in various electronic and optoelectronic devices. PMID- 29448657 TI - Numerical Analysis of the Temperature Impact on Performance of GaN-Based 460-nm Light-Emitting Diode. AB - The influence of temperature on the characteristics of a GaN-based 460-nm light emitting diode (LED) prepared on sapphire substrate was simulated using the SiLENSe and SpeCLED software programs. High temperatures impose negative effects on the performance of GaN-based LEDs. As the temperature increases, electrons acquire higher thermal energies, and therefore LEDs may suffer more from high current loss mechanisms, which in turn causes a reduction in the radiative recombination rate in the active region. The internal quantum efficiency was reduced by about 24% at a current density of 35 A/cm2, and the electroluminescence spectral peak wavelength was redshifted. The LED operated at 260 K and exhibited its highest light output power of ~317.5 mW at a maximum injection current of 350 mA, compared to 212.2 mW for an LED operated at 400 K. However, increasing temperature does not cause a droop in efficiency under high injection conditions. The peak efficiency at 1 mA of injection current decreases more rapidly by ~15% with increasing temperature from 260 to 400 K than the efficiency at high injection current of 350 mA by ~11%.

AB - The surface plasmon resonance (SPR) properties of Au/Ag bimetallic thin-film nanostructures were investigated to improve the chemical stability and the figure of merit (FOM) in the SPR sensors. The SPR characteristics such as resonance angle, extinction ratio, and full width half maximum (FWHM) were calculated by the simulation of the finite-difference time-domain method and were measured using the laser with a 632.8 nm wavelength in the Kretschmann-Raether configuration. The measured resonance angle, extinction ratio, FWHM of Au(20 nm)/Ag(20 nm) thin-film nanostructure were found to be 44 degrees , 0.8, and 1.4 degrees , respectively. The FOM values were determined to be 56.9 for Au/Ag bimetallic thin-film, 47.9 for Au(50 nm) single thin-film, and 89.1 for Ag(50 nm) single thin-film. Also the sensitivity values were about 53.5, 57.0, and 57.8 degrees /RIU for Au(50 nm), Ag(50 nm), and Au(20 nm)/Ag(20 nm) thin-film nanostructures in the SPR sensors, respectively. The SPR properties of Au/Ag bimetallic thin-film nanostructures were compared with those of the Au and Ag single thin-film nanostructures.

AB - Lower-arm, one of the components in automotive suspension module, has been fabricated by MAG welding in general which is lap jointed with 2 mm thick galvannealed steel sheet (SGAPH440). This welding process produces some problems such as significantly much spatters and weld defects of porosity in welded joint, which degrades productivity and weldability. Therefore, in order to solve these problems, this study has been tried to apply two types of solid wires with different chemical composition rate of Si and Mn, in MAG welding process. Moreover, the laser welding process has been adopted to fabricate the low-arm and compared with those of MAG welding, in terms of mechanical and metallurgical characteristics. It was observed that in MAG welded joints, much more spatters were occurred in using solid wire with higher Si and Mn contains. The maximum tensile-shear strength in laser welded joints was approximately 16.7 kN, which was almost equal to that of in MAG welded joints. The microstructure showed ferrite and martensite in weld metal in MAG and laser welded joints indicating no significantly grain size change.

AB - TiO2 films with one, three or five layers were prepared on a glass surface using the sol-gel method. The crystal structure, the surface morphology and the thickness of the films were characterized by X-ray diffraction, atomic force microscopy and ellipsometry. The tribological properties of the TiO2 films were investigated by a tribometer. TiO2 thin films were eroded by sand-air injection. The erosion behavior and mechanism of TiO2 thin films in a sandstorm were analyzed by scanning electron microscopy. The results showed that the films were highly abraded with increased erosion speed and dose of sand. With an increase in film layers, the erosion resistance and wear resistance of the TiO2 films increased gradually. The erosion mechanism consists of the film being damaged mainly from the cutting action of micro-scratches from low angle erosion. Alternatively, for high angle erosion, the material is damaged mainly by squeeze deformation by the action of erosion. Because of the high strength and toughness of the TiO2 thin films, the wear of its coating from high angle erosion is more severe than that from low erosion angle.

AB - The atomic structures and the corresponding physicochemical properties of peptide coated Au nanoclusters determine their distinctive biological targeting applications. To learn the modulation of amino acid ligand on the atomic structure and electronic characteristics of coated Au core is the fundamental knowledge for peptide coated Au nanocluster design and construction. Based on our recent coated Au nanocluster configuration study (Nanoscale, 2016, 8, 11454), we built the typically simplified Au13(Cys-Au-Cys) system to more clearly learn the basic modulation information of amino acid ligand on Au core by the density functional theory (DFT) calculations. There are two isomers as ligand adjacent bonding (Iso1) and diagonal bonding (Iso2) to Au13 cores. The geometry optimizations indicate the adjacent bonding Iso1 is more stable than Iso2. More important, the Au13 core of Iso1 distorts much more significantly than that of Iso2 by Cys-Au-Cys bonding through the root-mean-square deviation (RMSD) analysis, which modulate their electronic characteristics in different ways. In addition, the frontier molecular orbital results of Au13(Cys-Au-Cys) isomers confirm that the Au cores mainly determine the blue shifts of Au13(Cys-Au-Cys) systems versus the original Au13 core in their UV-visible absorption spectrum studies. The configuration of Au13 core performs deformation under Cys-Au-Cys ligand modulation to reach new stability with distinct atomic structure and electronic properties, which could be the theory basis for peptide coated AuNCs design and construction.

AB - Few-layer MoS2 nanosheets have been successfully synthesized by a facile anionic surfactantassisted hydrothermal approach. The as-prepared samples are characterized by X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). It is found that the anionic surfactant sodium dodecylbenzene sulfonate (SDBS) plays a crucial role in the formation of MoS2 nanosheets with few layers and rich exposed edges. The electrochemical performances of the as-prepared samples are evaluated by cyclic voltammogram, galvanostatic charge-discharge and electrochemical impedance spectroscopy. Compared with the pristine MoS2 without SDBS, the MoS2 nanosheets show a high specific capacitance of 223 F g-1 and its capacitance can still maintained a stable specific capacitance of 147 F g-1 after 500 cycles at 1 A g 1. The enhancement in supercapacitors is attributed to few-layer structure and exposed active edges, which enables fast electron transportation between the electrode and electrolytes. Therefore, the MoS2 nanosheets will be a suitable candidate for electrochemical supercapacitor applications.

PMID- 29448666 TI - Growth of Large-Area 2D MoS2 Arrays at Pre-Defined Locations Using Stencil Mask Lithography. AB - The growth of MoS2 layers of desired dimensions at predefined locations is essential for fabricating opto-electronic devices based solely on MoS2 or on hetero-structures based on MoS2. Here we present a new route for patterned growth of MoS2 by combining radio frequency (RF) magnetron sputtering, stencil mask lithography and vapour phase sulfurization. The present method does not involve chemical etchants and organic photoresist and hence provides a simplified process of achieving MoS2 patterns. Here, the control over the number of layers (mono, few and bulk) of MoS2 is achieved by varying the thickness of Mo films. The statistical variation in thickness i.e., number of MoS2 layers within the individual patterns is investigated from Raman mappings which revealed the uniform growth of 3-4 MoS2 layers. From Kelvin probe force microscopy, the surface potential values of MoS2 patterns lie in the range -350 to -370 mV, which is consistent with 2D MoS2 layer with thickness of 3-4 layers. The surface potential analysis across individual patterns indicates weakly n-type doping of few layers MoS2 with Fermi level located ~0.83-0.85 eV below the conduction band edge.

AB - ZTO was prepared on SiOC/ITO glass and the electrical characteristics were analyzed in accordance with the annealing temperature to research the temperature dependence and an amorphous structure. SiOC annealed at 150 degrees C as a gate insulator became an amorphous structure. The ZTO annealed at 150 degrees C had the capacitance without any variation. However, the capacitance of ZTO on SiOC annealed at 150 degrees C was increased due to the reduction of energy loss. ZTO/SiOC transistor was observed the ambipolar transfer characteristics with high stability and mobility in accordance with the decrement of drain voltages as a result of tunneling effect. Therefore it was obtained that the SiOC annealed at 150 degrees C means the highest Schottky barrier (SB) at the interface of ZTO/SiOC as the optimization parameter.

AB - The effect of the curved fin top edge on the electrical characteristics of FinFETs was investigated. The curvature radius of the fin top edge for the FinFETs was changed from 0 to 5 nm in order to determine the optimum condition of the electrical characteristics for the devices. The on-current level of the FinFETs with a curvature radius of 5 nm of fin top edge was 24.45% larger than that of the FinFETs with a cuboid fin. The electron current density and the electron mobility of the fin top edge for the FinFETs were larger than those for the FinFETs with a cuboid fin. The electrical characteristics of the FinFETs with a curvature radius of 5 nm for the fin top edge showed the best performance due to the largest expansion of the effective channel region.

AB - n-Type nanocrystalline FeSi2/p-type Si heterojunctions were formed by using facing-target direct- current sputtering at room temperature. The J-V characteristic results revealed that the reverse leakage current is large and the response under illumination of near-infrared light is very weak. The capacitance voltage-frequency (C-V-f) and conductance-voltage-frequency (G-V-f) measurements were carried out at room temperature in order to estimate the series resistance (Rs) by using the Nicollian-Brews method and the density of interface state (Nss) by using the Hill-Coleman method. By estimation according to the Nicollian-Brews method, the Rs value increases with decreasing f value. The Rs values at zero bias voltage were 2.07 Omega at 60 kHz and 1.54 Omega at 2 MHz, which are consistent with those calculated by using the Cheung's and Norde's methods. The obtained Rs should be attributable to the Rs existing in the ohmic contact and neutral regions, which is the current-limiting factor for junctions. The nss values calculated by using the Hill-Coleman method were 2.70 * 1014 eV-1cm-2 at 60 kHz and 1.43 * 1013 eV-1cm-2 at 2 MHz. This result revealed the presence of interface states at the hetero-interface behaving as a leakage current center and a trap center of the photo-generated carrier, which degraded the junction properties at room temperature.

AB - A nanostructured deoxidized low-phosphorous copper (DLPC) was fabricated by three layer stack accumulative roll-bonding process. Three sheets of 1 mm in thickness, 30 mm in width and 300 mm in length were stacked up and roll-bonded to thickness of 1 mm by two-pass cold rolling. The bonded sheet was cut in three pieces of same length, then stacked up and roll-bonded to the thickness of 1 mm again. The evolution of nanostructure through thickness with three-layer stack ARB were investigated in detail. It was found that the microstructure has been evolved from a dislocation cell structure to a nano grained structure with the proceeding of ARB cycles. The average grain thickness of 45 MUm in initial decreased to 170 nm after 7 cycles of the ARB. The heterogeneity in microstructure through thickness was also largely decreased by the ARB. These results suggest that three layer stack ARB is an effective process for a formation of nanostructure of DLPC alloy.

AB - Hematite (alpha-Fe2O3) nanostructures have been extensively studied as photo anodes for the conversion of sunlight into chemical fuels by water splitting. A number of factors limit the photo-activity of pristine hematite nanostructures, including poor electrical conductivity and long penetration depth of light. Previous studies have shown that use of tin (Sn) as an n-type dopant can substantially enhance the photoactivity of hematite photoanodes by modifying their morphological, optical and electrical properties. This article presents impedance spectroscopic investigation of interplay between Sn-doping and the photoanode performance for photoelectrochemical water splitting using hematite nanostructure. Mott-Schottky measurements show that the Sn dopant serves as electron donor and increases the donor density of Sn-doped alpha-Fe2O3 nanostructured layer to 2.39 * 1019 cm-3. Photoelectrochemical impedance spectroscopy shows efficient photogenerated charge transfer from hematite to electrolyte in Sn-doped alpha-Fe2O3 nanostructure. The Sn-doped alpha-Fe2O3 nanostructure exhibit a photocurrent density of 1.2 mA/cm2 at 1.4 V versus RHE electrode.

AB - The selenium dioxide was used as the precursor to synthesize wide-size-ranged CdSe quantum dots (2.4-5.7 nm) via hot-injection route. The CdSe quantum dots are featured with high crystalline, monodisperse, zinc blende structure and wide emission region (530-635 nm). In order to improve the stability and quantum yield, a phosphine-free single-molecular precursor approach is used to obtain CdSe/CdS core/shell quantum dots. The CdSe/CdS quantum dots are highly fluorescent with quantum yield up to 65%, and persist the good monodispersity and high crystallinity. Moreover, the quantum dots white light-emitting-diodes are fabricated by using the resultant red emission core/shell quantum dots and Y3Al5O12:Ce3+ yellow phosphors as color-conversion layers on a blue InGaN chip. The prepared light-emitting-diodes show good performance with CIE-1931 coordinated of (0.3583, 0.3349), an Ra of 92.9, and a Tc of 4410 K at 20 mA, which indicate that the combination of red-emission QDs and yellow phophors as a promising approach to obtain warm WLEDs with good color rendering.

AB - Porous polymer electrolytes (PPEs) doped with nano-Al2O3 were prepared by a joint application of ultrasonic treatment and control evaporation in vacuum oven. The morphology, pore size distribution, thermal, electrochemical and mechanical properties of the PPEs were investigated. The porosity distribution of PPEs was uniform and their pore size was relatively modest. The total resistance (Rt) of PPEs with 10% Al2O3 is only 9 Omega at 80 degrees C. The maximum tensile strength of the PPEs membranes reached to 24.43 MPa. The results show that nano Al2O3 can improve the comprehensive performance of PPEs without compromising their conductivity and diplayed the good application prospects of Al2O3-modified PPEs for lithium-ion batteries.

AB - Lanthanide ion doped nanoparticles can coordinate with some organic ligands to form the inorganic-organic hybrid nanoparticles, which exhibit greatly enhanced luminescence as a result of the energy transfer from the organic ligands to the lanthanide ions. However, when coordinating with a single type of organic ligand, their luminescence excitation spectral bandwidth is still quite limited. In this work, Eu3+-doped LaF3 (LaF3:Eu3+) nanoparticles, as the model inorganic material, were synthesized using the hydrothermal method. Instead of coordinating with a single type of organic ligand as previously studied, the LaF3:Eu3+ nanoparticles simultaneously coordinate with both benzoic acid and 2-thenoyltrifluoroacetone to form the inorganic-organic mixed hybrid nanoparticles. The mixed hybrid nanoparticles possess a broadband excitation spectrum (200~400 nm) which perfectly covers the entire ultraviolet (UV) spectral range of the solar radiation. By down-converting the UV light to visible light, their broadband UV excitation spectrum will be extremely beneficial to the enhancement of the conversion efficiency of silicon solar cells.

AB - LiCl/NaA zeolite composites were successfully prepared by doping 1 wt%, 2 wt%, 5 wt%, and 8 wt% of LiCl into NaA zeolite. The humidity sensing properties of LiCl/NaA composites were investigated among 11% 95% relative humidity (RH). The LiCl/NaA composites exhibited better humidity sensing properties than pure NaA zeolite. The sensor made by 2 wt% Li-doped NaA zeolite possesses the best linearly in the whole RH.

AB - One-dimensional (1D) Co3O4 nanopillars were prepared by a facile hydrothermal calcination method, which involved low thermal decomposition of Co(OH)y(CO3)0.5(2 y) . 11H2O at different temperatures. Microstructure, lithium-storage performance and the conductivity of the Co3O4 nanopillars calcined at different temperatures were systematically investigated. It was revealed that the calcined temperature has an effect on the particle size, crystallinity, and morphology of the Co3O4 nanopillars, which further influenced its electrochemical performance. It was found that when the calcined temperature and time were 450 degrees C and 2 h, respectively, the obtained Co3O4 nanopillars with the length of 60-100 nm and width of 30-40 nm, presented good lithium-storage performance with a high reversible capacity of 805.8 mAh g-1 after 30 cycles at a current density of 100 mA g-1. In addition, the Co3O4 nanopillars electrode possessed the smallest semicircle diameter, which implied that Co3O4 nanopillars presented the lowest contact and charge-transfer impedances, originating from its good crystallinity and 1D nanocolumnar structure.

AB - Graphene oxide (GO) reinforced hydroxyapatite (HA) composites with various contents of GO (HA/GO-C) were synthesized with addition of cetyltrimethyl ammonium bromide (CTAB) by a wetchemical precipitation method using diammonium hydrogen phosphate ((NH4)2HPO4) and calcium nitrate (Ca(NO3)2 . 4H2O) as the initial reactants, and their structure, morphology, crystallization, specific surface area were studied by FT-IR, SEM, Raman spectroscopy, XRD and BET. Particularly, the influence of GO addition and appiled load on the friction coefficient of the obtained composites was investigated. Also, the influence of GO addition on microhardness of the composite was evaluated. The results suggested that HA successfully grafted over GO nanosheets whose structure was preserved. The layer spacing of HA/GO-C composite was enlarged by addition of CTAB in synthesis process. The friction coefficient of the composite gradually decreased with increase of GO content in composite and increased with increase in applied load. The microhardness of the composites increased with increase of GO content. The obtained HA/GO-C composites may have a potential application in biomedical engineering.

AB - Nanocrystalline diamond (NCD) films were grown by hot filament CVD and the precursor composition dependence of the structural properties was examined. Films grown at 1 and 2 CH4 Vol% were found to be NCD layers with grain sizes of ~23-25 nm while films grown at 3-5 Vol% were identified as the mixtures of microcrystalline diamond and graphitic phase. The sp2/sp3 bonded carbon ratio in the grown films increased as the CH4 content increased up to 3 Vol% and then decreased beyond 4 Vol%. Microstructure and deposition rate were also found to be affected by the precursor composition and the NCD film grown at 1 CH4 Vol% showed a very dense microstructure and the highest deposition rate of ~3 nm/min.

Er3+ ions concentrations were changed from 0.01 to 0.2 mol for the fixed Yb3+ ions concentration at 0.15 mol. The crystalline structures of the phosphors were investigated by X-ray diffraction (XRD).

AB - The junction temperature of high-power LED lighting was reduced effectively using a lens plate made from a thermally-conductive plastics (TCP). TCP has an excellent thermal conductivity, approximately 5 times that of polymethylmethacrylate (PMMA). Two sets of high-power LED lighting were designed using a multi array LED package with a lens plate for thermal simulation. The difference between two models was the materials of the lens plate. The lens plates of first and second models were fabricated by PMMA (PMMA lighting) and TCP (TCP lighting), respectively. At the lens plate, the simulated temperature of the TCP lighting was higher than that of the PMMA lighting. Near the LED package, the temperature of the TCP lighting was 2 degrees C lower than that of the PMMA lighting. This was well matched with the measured temperature of the fabricated lighting with TCP and PMMA.

AB - Atmospheric pressure plasma-enhanced chemical vapor deposition (AP-PECVD) technique and KrF excimer laser annealing (ELA) were employed for the fabrication of indium gallium zinc oxide thin-film transistors (IGZO-TFTs).

The improvements are attributed to the adjustment of oxygen vacancies in the IGZO channel to an appropriate range of around 28.3% and the reduction of traps at the high-k/IGZO interface.

It corroded to TiO2, alpha-Al2O3, and Cr2O3. From the early corrosion stage, not only the outward diffusion of Al, Ti, Cr, and Si but also the inward migration of oxygen occurred. As the corrosion proceeded, the outermost TiO2 layer, outer (Ti-depleted, (Al,Cr)-rich)-oxide layer, inner (Ti rich, (Al,Cr)-depleted)-oxide layer, and partially oxidizing innermost film formed on the oxygenaffected film.

AB - A direct mechanical nanomachining, tribo-nanolithography (TNL), has been developed to fabricate micro mold on Si substrate in mechanical milling mode. An atomic force microscope (AFM) tip is replaced by a lab-made Si cantilever with a polycrystalline diamond (PCD) tool. Mechanical cutting by PCD tool enables simple fabrication of micro molds with several tens of nanometers depth.

PMID- 29448686 TI - Effect of the Spray Distance on the Properties of High Velocity Oxygen-Fuel (HVOF) Sprayed WC-12Co Coatings. AB - In this study influence of spray distance on the properties of WC-12Co coatings deposited by HVOF was investigated. WC-12Co coating was sprayed at spray distance of 300, 385 and 450 mm. From microstructure observation, it is confirmed that the porosity of coatings increases with increasing the spray distance. The X-ray diffraction patterns indicate that the coatings consist of pure WC, W, and Co as well as W2C and Co6W6C phases. The increase of the spray distance accelerated the decarburization of coatings. From micro hardness tests, it was found that the hardness and the fracture toughness decreased with increasing spray distance. These mechanical properties would be related with not only porosity but also the degree of decarburization.

AB - Al5052 T butt joints with two skins (5 mm) and one stringer (3 mm) has been successfully welded by friction stir welding (FSW). Notably, this paper has been investigated the effect of tool shape on welded formation mechanism and mechanical properties. The used shapes of tool pin are two types which are cylinder (type 1) and frustum (type 2). Dimension on two types of tool pin shape is respectively pin length of 4.7 mm and pin diameter of frustum type of top (5 mm) and bottom (3 mm). The results of experiment show that inner defects in FSWed T-joints increase significantly in accordance with traverse speed. The maximum tensile strength of welded joint fabricated using type 1 is equivalent to 85% that of the base metal, which is approximately 10% higher than that of type 2. Because welded joint of type 1 has more smoothly plastic flow in comparison with type 2. Consequently, the results show that type 1 is better appropriate for friction stir welded Al5052 T butt joints than type 2. PMID- 29448688 TI - Effect of Self-Heating on the Electrical Characteristics of Strained Si FinFETs. AB - Self-heating effect (SHE) on the electrical characteristics of fin field-effect transistors (FinFETs) model with a strained Si channel was investigated by using a three-dimensional simulation tool. Strain was applied from 0.1 to 2.0 GPa by changing Si mole fraction of the Si1-xGex. Simulation results showed that the drain current of the strained Si FinFETs increased with increasing applied strain from 0.5 to 2.0 GPa. The drain current of the FinFETs under strain of 2.0 GPa increased up to 20.59 MUA. While the drain current of the FinFETs without a SHE increased with increasing strain, the increase of the drain current generating from the strain interrupted the applications for the practical device operation due to a large SHE. The drain current decreased due to the increased scattering resulting from the increased device temperature with an increase in the SHE.

AB - Three-dimensional (3D) NAND flash memory devices having a poly-silicon channel with grain boundaries, the cylindrical macaroni channel being outside the inter oxide filler layer and inside the tunneling oxide layer, were evaluated. The effects of the grain size, grain boundary trap density, and interface trap density at the interfaces between the channel and the oxide layers on the electrical characteristics of 3D NAND flash memory devices were investigated. The electron density of the channel was changed depending on the grain boundary trap density and the position of the grain boundary trap in the channel. The grain boundary traps increased the potential barrier and decreased the electron density of the channel. The threshold voltage increased with increasing grain boundary trap density and interface trap density.

AB - Accumulative roll-bonding (ARB) is the most appropriate process for sheet-shaped materials because it can be carried out readily by utilizing the conventional rolling apparatus. In this study, a nanostructured AA1050/AA5052 Al alloy sheet was successfully fabricated by four-layer stack ARB process. The ARB of AA1050 and AA5052 alloy sheets was performed up to 6 cycles without a lubricant at ambient temperature. The sample fabricated by the ARB was a multi-layer aluminum alloy sheet in which AA1050 and AA5052 layers are alternately stacked. The layer thickness of the each alloy became thinner and elongated to the rolling direction with the number of ARB cycles. The grain size decreased with increasing of the number of ARB cycles, after 6 cycles it became about 180 nm in thickness. The fraction of high angle grain boundaries increased with the number of ARB cycles. The tensile strength also increased with the ARB, it reached 305 MPa which is about 2.1 times that of the as-received AA1050. The mechanical properties of a multi-layer AA1050/AA5052 alloy fabricated by the ARB were compared to those of the other materials.

The Aluminum alloy melt was held at 800 degrees C and then poured into a mould at 200 degrees C. Aluminum alloys were hot extruded into a rod that was 12 mm in thickness with a reduction ratio of 38:1. AlTiB addition to Al-0.15Si-0.2Fe-0.3Cu-0.15Zn-0.9Mn based alloys resulted in the formation of Al3Ti and TiB2 intermetallic compounds and grain refinement. With increasing of addition AlTiB, ultimate tensile strength increased from 93.38 to 99.02 to 100.01 MPa. The tensile strength of the as-extruded alloys was improved due to the formation of intermetallic compounds and grain refinement.

AB - Calcium carbonate (CaCO3) and monodisperse calcium oxide nanoparticles (CaO NPs) are prepared by the calcination of solid-state calcium oleate precursor in air condition. The effect of calcination temperature on the synthesis of CaCO3 and CaO NPs is examined. The polymorphism is confirmed by X-ray diffraction spectroscopy (XRD), Fourier transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA). The sample morphologies including their size and size distribution are investigated by field emission scanning electron microscopy (FESEM). Calcination of calcium oleate between 400 and 550 degrees C results in CaCO3 NPs with mean sizes from 82 to 98 nm, whereas monodisperse spherical CaO NPs are obtained at 650 degrees C and an average size is estimated to be 40 nm. Beyond 650 degrees C, the size of CaO NPs increases with broad size distribution. The results of this study provide a novel approach to monodisperse CaCO3 and CaO NPs that can be applied in a variety of fundamental and industrial fields.

AB - It is a key to develop novel electrode materials with high energy and power density for advanced batteries to meet the demand of electric vehicles (EVs). Manganese cobalt oxides which can react with a large number of ions from the electrolyte for electrochemical energy storage are developing into the promising electrode materials. In this work, well-ordered MnCo2O4.5 nanorod arrays (MCO NRAs) are prepared on Ni foam by a general route of hydrothermal growth and low temperature annealing treatment. The samples deliver a high initial capacity of 1402.6 mAh g-1 at the current density of 100 mA g-1 and rate capacity of 528 mAh g-1 when the current density is improved 10 times as binder-free anodes for Li ion batteries (LIBs). After 60 cycles at the current density of 200 mA g-1, the MnCo2O4.5 nanorods still achieve 603 mAh g-1 with capacity retention of 66% (compared with the second discharge capacity). The superior electrochemical properties are due to the fascinating architecture which increases the reaction area and structural stability, reduces ion and electron transport distance and provides good strain release. Hence, MnCo2O4.5 nanorod arrays are promised as advanced anodes for future LIBs with completely meeting the demand of EVs. PMID- 29448694 TI - Two Methods for Intercalation of Surfactants into Graphite Oxide. AB - The intercalation properties of graphite oxide are important; however, the specific processes and mechanisms associated with intercalation have rarely been elucidated. In this paper, two types of surfactants, polyvinylpyrrolidone and tetradecyltrimethylammonium bromide, were used to thoroughly explore the intercalation properties of graphite oxide. The polyvinylpyrrolidone and tetradecyltrimethylammonium bromide-intercalated graphite oxide composites were synthesized under different conditions and characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, X-ray energy dispersive spectroscopy, and transmission electron microscopy. It was found that polyvinylpyrrolidone could be directly intercalated into the graphite oxide layers and tetradecyltrimethylammonium bromide could not effectively react with the waterdispersed graphite oxide. With a low quantity of polyvinylpyrrolidone, only a part of the graphite oxide was intercalated, and the interlayer spacing of the polyvinylpyrrolidone-intercalated composites increased as the polyvinylpyrrolidone: graphite oxide mass ratio increased. When the graphite oxide was dispersed in a 0.05 N NaOH solution, the tetradecyltrimethylammonium bromide rapidly reacted with the graphite oxide, while the mixture of polyvinylpyrrolidone and graphite oxide could not be effectively separated. The intercalated spacing of the tetradecyltrimethylammonium bromideintercalated graphite oxide increased with the tetradecyltrimethylammonium bromide: graphite oxide mass ratio, but its crystalline structure was not as ordered as the polyvinylpyrrolidone-intercalated graphite oxide prepared in the water solution. The infrared spectra of the two surfactant-intercalated graphite oxide samples revealed that the polyvinylpyrrolidone is bonded to the graphite oxide via hydrogen bonding, while the tetradecyltrimethylammonium bromide is bonded via ionic bonding. The mechanism analysis indicated that the polyvinylpyrrolidone could directly enter the graphite oxide layers in the water solution because of the driving force of hydrogen bonding. However, processes such as graphite oxide exfoliation, reactions between the graphite oxide and tetradecyltrimethylammonium bromide, and reaggregation of the graphite oxide sheets are necessary for the formation of tetradecyltrimethylammonium bromide-intercalated graphite oxide.

AB - In this study, Titanium dioxide (TiO2) microspheres were synthesized by a hydrothermal method from the same precursor: titanium sulfate. Two different TiO2 microspheres with different surface and crystallinity were fabricated by adding different additives as the photoanode of dye-sensitized solar cells (DSSCs). The growth mechanisms of the TiO2 microspheres were discussed. The effect of surface status and the crystallinity of the TiO2 microspheres on the photovoltaic characteristic of DSSCs were investigated. It was found that when the TiO2 microsphere with loose construction and rough surfaces along with better crystallinity was applied on photoanode, the DSSC exhibited better photoelectric performance than the DSSC with dense TiO2 microsphere photoanode. TiO2 microsphere with loose construction and rough surface applied to photoanode, the DSSC showed photoelectric conversion performance of 3.83% which is 53.8% higher than DSSC with dense and smooth TiO2 microsphere photoanode, and it is also superior to the DSSC with P25 photoanode.

AB - A TiO2 nanostructure was prepared on a Ti3SiC2 substrate with different water and NH4F concentrations in a fluoride-containing ethylene glycol electrolyte via an anodization process using the same constant-anodization potentials, anodization duration and temperature. The as-prepared samples were characterized by a field emission scanning electron microscope equipped with an energy dispersive X-ray spectroscope, as well as by X-ray diffraction and X-ray photoelectron spectroscopy. The influence of the anodizing parameters and annealing temperature on the morphology of the nanostructure and the phase structure was studied. The results showed that the scattered TiO2 nanotubes and TiO2 nanoporous films were successfully fabricated in the glycol electrolyte containing (3.0 wt%) NH4F +(5.0 vol%) H2O. The as-prepared samples before calcination were amorphous and could transform to the anatase phase at temperatures higher than 500 degrees C. As the annealing temperature increased, the crystallization of the anatase phase was enhanced, and the rutile phase appeared at 600 degrees C. The as-prepared samples mainly consisted of oxides. Ti2O3 and SiO2 oxides were present in addition to TiO2. PMID- 29448697 TI - Characterization of DDAB/Cholesterol Vesicles and Its Comparison with Lipid/Cholesterol Vesicles. AB - Vesicles prepared by synthetic surfactant, DDAB (dilauryldimethylammonium bromide), were modified with cholesterol and their membrane surface properties of the vesicle were characterized through the analyses of fluorescent probes, such as Laurdan (6-lauroyl-2-dimethylaminonaphthalene) and DPH (1,6-diphenyl-1,3,5 hexatriene). The self-assembly of DDAB with cholesterol showed stable vesicle structure with a mean diameter of 127 nm through the dynamic light scattering analysis. While the DDAB vesicle showed high polarity and high fluidity, the modification of the DDAB vesicle with cholesterol lead to the formation of "heterogeneous phase" on the vesicle membrane. DDAB:cholesterol = 70:30 vesicle showed unique characteristics that represents polar environment but lower fluidity. A novel platform for the chemical process in aqueous media can be expected by using the artificial surfactant vesicles modified with cholesterol. PMID- 29448698 TI - Rapid Macroscopic-Scale Assembly of Ag Nanowires at the Water/Air Interface. AB - Rapid macroscopic-scale assembly of Ag nanowires was demonstrated through facile self-assembly at the water/air interface. This self-assembly was induced by heating due to the surface tension effect and convection. Interestingly, a rippled hairstyle superstructure was observed when the aqueous dispersions of thinner Ag nanowires were heated. Applying the Euler buckling theory for a set of aligned Ag nanowires, it was found that the water surface tension was sufficient to bend or buckle these free Ag nanowires trapped between two nanowire stripes, which resulted in the formation of the rippled hairstyle superstructure. However, the formation of the nanowire stripes was driven by steric repulsion of nanowires along with their short-range van der Waals interactions and later lateral capillary attraction between large building blocks. Such control over self assembly is key for designing hierarchically ordered structures, which opens a new opportunity in the exploration of novel properties and the development of new applications.

Synthetic cubic zirconia powders had homogeneous, nanoscale, and less-agglomeration characteristics.

PMID- 29448700 TI - UV Photoluminescence of Alumino-Germano-Silicate Glass Optical Fiber Incorporated with Gd2O3 Nano-Particles Upon Illumination of Xenon-Lamp. AB - Alumino-germano-silicate glass optical fiber incorporated with Gd2O3 nano particles (NPs) was developed by using the modified chemical vapor deposition and the drawing process. The formation of spherical Gd2O3 NPs in the fiber core with average diameter of 10.8 nm was confirmed by the TEM. The distinct absorption peaks in the fiber preform appearing in the UV region at 205, 247, 253, 274, and 312 nm were due to the incorporated Gd2O3 NPs via reorganization of the seven 4f electrons into various multiplets of Gd ions. In the case of the optical fiber obtained by drawing of the preform at high temperature about 2150 degrees C, absorption peaks due to Gd2O3 NPs were found to appear at 383 and 455 nm, which were red-shifted from 274 and 312 nm of the preform, respectively, and it may be due to increase in the size of Gd2O3 NPs after the drawing process. To investigate the photoluminescence (PL) property for UV sensor applications, the PL of the fiber was obtained by illumination of the Xenon-lamp. A PL band appeared in the wavelength band from 370 nm to 450 nm, centering at about 400 nm, which can be attributed to the presence of Gd2O3 NPs embedded in the fiber core. It was also found that the PL intensity at 400 nm showed linear dependence with the excitation power from 0 to 400 W.

AB - Strain compensation for multiple-quantum wells (MQWs) relative to the efficiency improvement of infrared light-emitting diodes (IR-LEDs) was investigated through the use of an InxGa1-xP strain barrier. The InxGa1-xP barrier, which was inserted between the n-confinement and active regions, developed for the reduction of lattice-mismatched strains in GaAs/AlGaAs and InGaAs/GaAs MQWs. Through photoluminescence, improved intensity was displayed in InGaAs/GaAs MQWs having InxGa1-xP strain barriers, with a significant increase in the intensity observed at the In0.47GaP strain barrier. This result is attributed to strain compensation between the In0.47GaP tensile strain barrier used and the In0.07GaAs compressive strain in MQWs.

AB - The atomic layers of transition metal dichalcogenides (TMDCs, MX2; M = Mo or W; X = S, Se, or Te) are of great interest in the areas of photonics and optoelectronics due to the correlation between valley orbital, spin, and optical helicity; the compositional tuning of exciton bandgaps in visible and near infrared spectra; and the bandgap modification from indirect for bilayer or multilayer to direct for monolayer. The derivative of the O'Donnell and Chen relation is analyzed as a function of temperature and gives the relationship between the change in entropy of exciton formation and the bandgap energy. The analysis suggests the change in entropy of exciton formation with higher energy phonons (~100 meV) is constant until ~90 K while lower energy phonons (~10 meV) approaches a constant value of -2skB between ~250 K and ~300 K where s is the strength of electron-phonon interaction and kB is the Boltzmann constant. Increased scattering and spontaneous decay probabilities explains the amplified electron-phonon interaction when the phonon energy is large. The change in exciton formation entropy can be increased ~3-fold while the bandgap is managed through the electron-phonon coupling strength.

AB - Cobalt oxide spinel thin films doped with Ni and Li were deposited on c-sapphire single crystal substrates at various substrate temperatures and oxygen partial pressures by pulsed laser deposition. The effects of the doping and processing parameters on the crystal structure, electrical and optical properties of cobalt oxide base spinel thin films were analyzed by XRD, four point probe and UV spectrometry. The electrical conductivity increased with increasing Ni doping concentration, x, up to x = 0.7. The thin films grew on the sapphire substrates with a strong (111) preferred orientation. Li0.1Ni0.6Co2.3O4 spinel phase decomposed to a rock salt phase when the oxygen partial pressure was lower than 5 mtorr. The electrical conductivity decreased rapidly with the formation of a rock salt phase due to the limited charge transfer between the divalent and trivalent cations.

AB - A series of ordered mesoporous silica (OMS) SBA-15 supports with different morphologies were prepared by different synthetic methods to investigate the effect of the characteristics of the morphology of OMS on the ethylene dimerization outcomes. After additions of Ni and Al species into the SBA-15 support, a dimerization reaction of ethylene was performed using a fixed-bed reactor. Rod-type Ni-Al-SBA-15 with a small micron size showed better catalytic performance compared to those of the other catalysts. From these catalytic results, the particle size and morphology of a SBA-15 support critically influenced the catalytic activities and lifetimes of the dimerization catalysts. The optimum reaction pathway in the Ni-Al-SBA-15 catalyst enhanced the overall catalytic performance due to the suppression of the further oligomerization of ethylene and butenes. Moreover, ethylene dimerization was investigated over the rod-type Ni-Al-SBA-15 catalyst to discover an optimum reaction condition. The maximum yield of butenes was 24.7% at 300 degrees C at 11.5 bar with a WHSV of 1.5 h-1.

The structural, morphological and physiochemical properties of the samples were investigated by analytical techniques. UV-Vis-DRS analysis confirmed light absorbance edge of composites was sharply red-shifted to the visible region with increasing graphite and SiO2 content.

AB - The selective laser melting (SLM) process parameters, which directly determine the melting behavior of the metallic powders, greatly affect the nanostructure and surface roughness of the resulting 3D object. This study investigated the effect of various laser process parameters (laser power, scan rate, and scan line spacing) on the surface roughness of a nickel-chromium (Ni-Cr) alloy that was three-dimensionally (3D) constructed using SLM. Single-line formation tests were used to determine the optimal laser power of 200 W and scan rate of 98.8 mm/s, which resulted in beads with an optimal profile. In the subsequent multi-layer formation tests, the 3D object with the smoothest surface (Ra = 1.3 MUm) was fabricated at a scan line spacing of 60 MUm (overlap ratio = 73%). Narrow scan line spacing (and thus large overlap ratios) was preferred over wide scan line spacing to reduce the surface roughness of the 3D body. The findings of this study suggest that the laser power, scan rate, and scan line spacing are the key factors that control the surface quality of Ni-Cr alloys produced by SLM.

AB - In this study, we present the microwave-assisted growth (MAG) of ZnO nanorods (ZNRs) using a preheating hydrothermal method under tailored preheating and postheating growth conditions. The perimeters such as solution concentration, preheating time, and postheating time, were changed to optimize ZNR growth and the growth was carried out in a domestic 850 watt microwave oven. Preheated solution was utilized as an accelerator to increase the aspect ratio of the ZNRs and reduce the fabrication time. Because of a long fabrication time and limited length in the conventional MAG method, preheating condition was used for efficient growth of nanorods through homogeneous nucleation in the solution and then heterogeneous nucleation of the formed ZNRs on seeded substrate during postheating process. The nanostructures were characterized with scanning electron microscopy to look at the morphology and dimensions. Dimensions of ZNRs kept on increasing as the molar concentration went higher. Preheating time highly affected the morphology, dimensions, and aspect ratio of ZNRs and postheating time not only ensured the stability of ZNRs with substrate due to heterogeneous nucleation process but also influenced the morphology of ZNRs.

AB - This study investigated the cavitation erosion resistance of electroless Ni-P (EN) coated gray cast iron (GCI) in seawater solution. Furthermore, the optimum coating design parameters were examined to minimize cavitation erosion damage through analysis of variance (ANOVA) based on the L9 orthogonal array. In this study, four coating design factors were used: concentration of source of nickel (A), concentration of reducer agent (B), deposition temperature (C), and pressure of shot peening (D). In accordance with the regulation of the modified ASTM G32, the cavitation erosion experiment was conducted for 1 hour in a seawater solution to find the optimum design parameters which can minimize the cavitation erosion damage. Besides, ANOVA was performed to verify the contribution of each coating design parameter. As a result, the concentration of reducer agent among the EN process parameters was determined as the most significant factor in the cavitation erosion behavior.

AB - WC based alloy coatings included different mass percent of Co and Cr have been synthesized on high carbon steel by using a facile high velocity oxy-fuel spray method. The mechanical nature of the coating films has been investigated by micro vickers hardness and fracture toughness. X-ray diffraction (XRD) and EDX analyses indicate that the three different samples (WC-10Co-4Cr, WC-17Co, and WC-12Co) consist of pure WC, W, Cr, and Co constituents as well as W2C and Co6W6C phases. The SEM and image analysis results show that WC-10Co-4Cr condition has higher porosity than those of WC-17Co, and WC-12Co coatings. WC-17Co coating showed the highest value in the hardness and fracture toughness test among three different samples. The obtained results revealed that the mechanical properties of WC based alloy coatings synthesized by a facile high velocity oxy-fuel spray method is very sensitive to Co content.

AB - The modified surface during implantation is considered to be an effective strategy to improve high adhesion of bone cell and osseointegration activity. In this paper, the TiO2 barrier oxide Layer has been fabricated by using the ion characteristic of an electrolytic solution, the surface characteristics have been investigated by EDS, XPS, and FE-SEM. From the analysis of the chemical states, phosphorus and calcium were observed in the TiO2 barrier layer, which were penetrated from the electrolyte into the oxide layer during deposit process. In addition, Ca 2p spectrum was identified into two peaks for Ca 2p3/2 and 2p1/2 at 347.4 and 351.3 eV, which are related to hydroxyapatite. Also, P spectrum was confirmed into two peaks for P1/2 and P3/2 levels with binding energy 134.2 and 133.4 eV, respectively. Thus, the incorporated phosphate species were found mostly in the forms of HPO-4, PO-3. From the result of biological evaluation in simulated body fluid (SBF), the apatite morphologies were effective for bioactive property on the modified surface.

AB - Aluminum and its alloys, due to their low density, high specific strength and high corrosion resistance amongst various structural materials, are used in a wide range of industrial applications for different aqueous solutions. In the present study, we studied effects of Ce addition on microstructure and mechanical properties of Al-2Li-1Cu-0.8Mg-0.1Zr alloys. The melt was held at 780 degrees C for 20 min and poured into a mold. And as-cast Al alloys were hot-extruded into a plate that was 4 mm in thickness with a reduction ratio of 14:1. The extruded plates were held at 540 degrees C for 4 hr in water quenching to solution treatment them. As-extruded Al-2Li-1Cu-0.8Mg-0.1Zr-xCe (x = 0.3, 0.6, 0.9 and 1.2 wt.%) alloys are composed of Al, AlLi, AlCuLi and Al11Ce3 phases. By increasing the Ce content from 0 to 1.2 wt.%, the Al11Ce3 phase is increased, after solution treatment the AlLi and AlCuLi phases are decreased. With increasing Ce addition from 0 to 1.2 wt.%, the average grain size of the as-extruded Al alloys were decreased slightly from 100.7, 113.74, 84.3, 74.7 and 61.7 MUm and ultimate tensile strength was decreased slightly from 267.59, 264.92, 237.40, 220.93 and 207.83 MPa at room temperature. After solution treatment, ultimate tensile strength was measured with 205.13, 198.12, 195.50, 198.27 and 208.01 MPa at room temperature.

Structural and optical properties of the nanostructures were investigated by using a variety of techniques including X-ray diffraction (XRD), scan electron microscope (SEM), room-temperature photoluminescence (PL), and Raman scattering. The results showed the growth mechanism of ZnO nanostructures grown on a-GaN is Volmer-Weber (VW) mode, which is due to the high interfacial free-energy between a-plane ZnO and GaN. Meanwhile, compressive strains were revealed to exist by the optical characterizations. And the strengths were found to reduce with increasing growth time. PMID- 29448716 TI - Templated Growth of Pd Nanoparticles Using Sputtering Deposition Process and Its Catalytic Activities. AB - A simple method based on sputtering deposition of Pd onto mesoporous SiO2 (SBA 15) was employed to produce supported Pd nanoparticles (NPs) that can be used as hydrogenation catalysts. The use of sputtering deposition eliminates contaminants and avoids additional drawbacks of traditional chemical methods applied to prepare heterogeneous supported metal catalysts. A mechanical resonant stirrer was used to revolve the SBA-15 powder and ensure homogeneous distribution of the Pd NPs over the support. The SBA-15 pores act as templates for Pd NPs and drive nanostructure growth. Consequently, the NPs obtained have the same diameter as that of the SBA-15 channels (~5 nm) and elongated particles are formed as sputtering deposition increases. The SBA-15 supported Pd NPs (Pd NPs/SBA-15) were tested in a probe hydrogenation of cyclohexene reaction to evaluate the catalytic activity of the Pd NPs. Turnover frequency (TOF) of 2000 min-1 were achieved with the lower Pd NPs concentration (0.15 wt%) catalyst. PMID- 29448717 TI - Effect of UVB Light Exposure on Tensile Behavior of Carbon Nanotube Sheet. AB - The effects of ultraviolet B (UVB) exposure on the tensile behavior of CNT sheet was investigated in this study. Two types of CNT sheet, one acid treated and one un-treated, were directly exposed to UVB light for 500 hours. The exposure was done using a UVB lamp inside a dark chamber under room temperature ambient condition. The microstructure of the CNT sheets were studied both prior to and after UVB exposure using a scanning electron microscope. Upon completion of the exposure duration, the CNT sheet test coupons were tested mechanically in tension using a microtester to evaluate the tensile strength and behavior. The results were compared to those of the CNT sheet test coupons that were not exposed to UVB light. It was observed that the strength of the acid treated CNT sheet decreased after UVB exposure while the strength of the un-treated CNT sheet increased. Apart from slight changes in stiffness, the overall mechanical behavior with increasing applied load did not show much change after the exposure to UVB light. The microscopic analysis showed evidences of morphological changes in the CNT microstructure upon UVB exposure. These changes supported the change in mechanical strength as a result of the UVB exposure. PMID- 29448718 TI - Conductance Measurement of Pyrazine Molecular Junction with Cu and Ag Electrodes. AB - We have measured the conductance of pyrazine molecular junction contacting with Cu and Ag electrodes by using an electrochemical jump-to-contact based scanning tunneling microscopy break junction (ECSTM-BJ). While conductance values of 10 2.8 and 10-3.7 G0 are measured for pyrazineCu electrode, 10-2.1 and 10-3.3 G0 are found for pyrazine-Ag contact. The result shows that the conductance of pyrazine with Ag electrode is larger than that with Cu electrode, which can contribute to the different efficiency of electron transport along the molecular junction between Ag and Cu electrodes. The current work shows the important role for the electrode material in electron transport. PMID- 29448719 TI - Cost-Effective Fabrication of Inner-Porous Micro/Nano Carbon Structures. AB - This paper reports the fabrication of a new micro/nano carbon architecture array which owns the characteristics of inner-porous, desired conductivity and large effective surface area. The micro/nano inner-porous carbon structures were fabricated for the first time, with ordinary and cost-effective processes, including photolithography, oxygen plasma etching and pyrolysis. Firstly, micro/nano hierarchical photoresist structures array was generated through photolithography and oxygen plasma etching processes. By introducing a critical thin-film spin-coating step, and followed with carefully pyrolyzing process, the micro/nano photoresist structures were converted into innerporous carbon architectures with good electric connection which connected the carbon structures array together. Probably the inner-porous property can be attributed to the shrinkage difference between positive thin film and negative photoresist structures during pyrolyzing process. It is demonstrated that the simple method is effective to fabricate inner-porous carbon structures with good electric connection and the carbon structures can be used as electrochemical electrodes directly and without the addition of other pyrolysis or film coating processes. The electrochemical property of the carbon structures has been explored by cyclic voltammetric measurement. Compared with solid carbon microstructures array, the cyclic voltammetry curve of inner-porous carbon structures shows greatly enhanced current and improved charge-storage capability, indicating great potential in micro energy storage devices and bio-devices.

AB - A quantum dot coupled to two electrodes with spin-dependent splitting of chemical potentials (spin bias) is proposed as a detector of an individual electron spin. Spin polarized transport properties through the quantum dot have been investigated theoretically by means of the nonequilibrium Green's function formalism. We found that the direction of current flow is dependent on the electronic spin state in quantum dot. Measuring the direction of the current flow through the devices, we can determine the direction of the electronic spin state in quantum dot. This proposed detector provides a practical and all electrical approach to detect the electronic spin state in quantum dot structure.

AB - Quinary Ti-B-C-N-Si nanocomposite films were deposited onto AISI 304 substrates using a pulsed d.c. magnetron sputtering system. The quinary Ti-B-C-N-Si (5 at.%) film showed excellent tribological and wear properties compared with those of the Ti-B-C-N films. The steady friction coefficient of 0.151 and a wear rate of 2 * 10-6 mm3N-1m-1 were measured for the Ti-B-C-N-Si films. The oxidation behavior of Ti-B-C-N-Si nanocomposite films was systematically investigated using X-ray diffraction (XRD), and thermal analyzer with differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). It is concluded that the addition of Si into the Ti-B-C-N film improved the tribological properties and oxidation resistance of the Ti-B-C-N-Si films. The improvements are due to the formation of an amorphous SiOx phase, which plays a major role in the self-lubricant tribo layers and oxidation barrier on the film surface or in the grain boundaries, respectively. PMID- 29448722 TI - Characterization of Pulse Reverses Electroforming on Hard Gold Coating. AB - Effect of pulse reverse current (PRC) method on brass coatings electroplated from gold solution was investigated by various plating parameters such as plating duration, the anodic duty cycle, the anodic current density and the cathodic current density. The reversed current results in a significant change in the morphology of electrodeposits, improvement of the overall current efficiency and reduction of deposit porosity. With longer pulses, hemispherical surface features are generated, while larger grains result from shorter pulse widths. The porosity of the plated samples is found to decrease compared with results at the same time average plating rate obtained from DC or Pulse plating. A major impediment to reducing gold later thickness is the corrosion of the underlying substrate, which is affected by the porosity of the gold layer. Both the morphology and the hydrogen evolution reaction have significant impact on porosity. PRC plating affect hydrogen gold and may oxidize hydrogen produced during the cathodic portion of the waveform. Whether the dissolution of gold and oxidation of hydrogen occur depends on the type of plating bath and the plating conditions adapted. In reversed pulse plating, the amount of excess near-surface cyanide is changed after the cathodic current is applied, and the oxidation of gold under these conditions has not been fully addressed. The effects of the current density, pulse-reverse ratio and brightener concentration of the electroplating process were investigated and optimized for suitable performance.

AB - Innovative nanoscale ZnO-laponite-polyvinyl alcohol composites (NZLPc) were developed as a valid alternative to nanoscale photocatalysts for mineralization of chlorinated hydrocarbons without difficulties in recovery of nanoscale photocatalyst particles. NZLPc were synthesized by mixing nanoscale ZnO particles with laponite in PVA solution, and by crosslinking PVA solution in the presence of boric acid (>=1.6 M). Different mixing ratios of the raw materials were investigated to develop the stable NZLPc, and X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray spectroscopy, and transmission electron microscopy characterizations were performed. From the results, a 3:1:1:10 ratio of ZnO, laponite, PVA, and deionized water by weight was appropriate to form spherical NZLPc with high porosities and enhanced mechanical strengths. Also, the degradation efficiencies of trichloroethylene were significantly improved with both NZLPc and UV irradiation, indicating that ZnO mediated heterogeneous photocatalytic degradation occurred. Thus, the proposed synthesis of NZLPc paves a way for the economical and effective photocatalytic approach to remove the recalcitrant organic compounds in water through the multiple reaction processes (i.e., sorption, photolysis, and photocatalysis).

AB - To evaluate the sterilize efficiency of nano-sized recycled aggregates (RAs), several types of RAs were examined for the purpose of environmental stamping out procedure. The poultry (e.g., chicken) was selected as a target livestock of epidemic disease, and the blast furnace slag (BFS), fly ash (FA), slaked lime (SL), nano-cerium (n-Ce) and shell (Sh) were used as the RAs materials. The fermented solution of effective microorganisms (EM) was added to decompose the target livestock. Various kinds of lab-scale reactor were operated to examine the effects of RAs volume; high and low volume of RAs (e.g., 1.89 w/v% and 1.14 w/v% of RA in solution, respectively), and the effects of EM concentration (e.g., concentrated solution (100%) and diluted solution (12.5%)) with tested in different reaction time. The number of microorganisms after batch tests was counted for the sterilized effects of RAs, and organic matters (e.g., chemical oxygen demand (COD)) and inorganic matters (e.g., suspended solids (SS), heavy metals and potential ions) were analyzed before and after adsorption process. The cases of SL and n-Ce showed high removal of microorganism in the batch of high concentrated EM for 20 days. However the other RA materials were less effective on the sterilization especially in lower volume of RAs. In diluted EM (e.g., 12.5%) tests, most RAs have high sterilization efficiencies in the short periods of batch reaction regardless of RAs types, and it was more effective with longer reaction time. The BFS and n-Ce exhibited higher surface area than others and they adsorbed highly heavy metals in water. The results suggested that the concentration of target organism was the most important to determine sterilization and adsorption properties of RAs.

AB - We present a light trapping structure consisting of gold and silver (AuAg) bimetallic non-alloyed nanoparticles (BNNPs) on a silicon dioxide (SiO2) spacer layer over crystalline silicon (c-Si) film, designed to improve the absorption of thin-film c-Si solar cells. Prior to fabrication of the AuAg BNNPs on the SiO2 spacer layer, numerical investigations were carried out using electromagnetic field simulation following the finite-difference time-domain method. The hemispherical Au8Ag8 BNNPs were fabricated and deposited on a 15 nm-thick SiO2 spacer layer, which enhanced light trapping in the c-Si film over a broad wavelength range (450-1100 nm). Specifically, more than 85% of the incident light was absorbed in the c-Si film at 620 nm wavelengths due to the strong scattering of the Au8Ag8 BNNPs. To the best of our knowledge this is the first case presenting such a theoretical calculation and experimental study of the efficient light trapping by AuAg BNNPs on space layer for increasing the absorption in thin film c-Si solar cells.

AB - In this study, the microstructure and mechanical property of Al/Cu clad material fabricated by differential speed rolling at room temperature were evaluated. Al and Cu plates were prepared and mechanically cladded at a differential speed ratio of 2:1 between the upper and lower rolls. Post- heat-treatment was carried out after the mechanical cladding at 400 degrees C for 60 min to induce the formation of intermetallic compound layers at the bonded interface of Al/Cu. As a result, differential speed rolling afforded a soundly cladded interface without any defects such as voids and cracks. In addition, intermetallic compound layers such as Al4Cu9 and Al2Cu were formed at the mechanically bonded interface during post-heat-treatment for 60 min, which led to an increase in Vickers microhardness value more than 30% relative to the base material. Therefore, we systematically explained the relationship between formation of intermetallic compounds and mechanical property of Al/Cu clad materials in this study.

AB - We proffer NH4OH-oriented and pH-dependent growth of ZnO nanostructures via a microwaveassisted growth method. The fabrication of ZnO nanorods (ZNRs), nanoflowers (ZNFs), nanostars (ZNSs), and nanotetrapods (ZNTs) is presented. NH4OH was used as a mineralizer to change the solution pH for nanostructure growth, where temperature and other variables were fixed. Because of an efficient heat transfer and facile growth of nanostructures, a domestic microwave oven was used to facilitate the nanostructure growth in the span of just 10-15 min. The results showed that the growth of ZnO nanostructures was dependent upon the number of growth units and ZnO nuclei present in the solution, which ultimately depend upon the pH of the solution. At the outset, without the addition of NH4OH, the pH of the solution was ~6.8 and the ZNRs were formed in the solution or on a seeded substrate which persisted in the pH range of ~6.8-9. An abrupt change in the shapes and the types of the nanostructures was observed when the pH was boosted beyond 10. A transition from ZNRs to ZNFs was observed at pH 10 and ZNFs were formed at pH 11. The solution gave birth to ZNSs and ZNTs when the pH was further raised to 12 and 13, respectively.

AB - Recently, numerous researchers are interested in the development of new air filter because of air pollution caused by rapid industrialization and urbanization. The major concerns in developing air filters are: pressure drop and filtration efficiency which are considered significant. As the pressure drop increases, the energy consumption becomes high. In this study, we developed a novel air filter (polyurethane fiber mat) for nano size filtration using a mass production electrospinning, which is expected to enhance filtration efficiency and pressure drop effects. To determine the optimal electrospinning conditions for filter efficiency, various concentrations (8, 10, 12 wt/wt%) of thermoplastic polyurethane were prepared and employed. Scanning electron microscope (SEM) and Fourier transform infrared spectroscopy (FT-IR) were used for fiber characterization, and finally, efficiency test was conducted to evaluate the filter performance of developed nanofiber-based air filter. From this study, it could be concluded that optimization by adjusting the polymer concentration and electrospinning operating condition was the best efficient alternative method to fabricate nano-fibrous air filter system with improved filtration performance.

The carbon nanostructures of the sampled particles were characterized using various techniques. The results showed that the soot sample collected from the 4-stroke engine, which burned Bunker C, has a higher degree of order of the carbon nanostructure than the sample collected from the 2-stroke engine, which burned Bunker A. Furthermore, the difference in the exhaust gas temperatures originating from the different engine and fuel types can affect the nanostructure of the soot emitted from marine diesel engines.

AB - Fe is intentionally added in order to form the Fe intermetallic compounds (Fe IMCs) during casting. Field emission scanning electron microscope with energy dispersive spectrometer (EDS) was conducted to understand microstructural changes and chemical composition analyses. The needlelike Fe-IMCs based on two dimensional observation with hundreds of micro size are modified to fragmented particles with the minimum size of 300 nm through clod rolling with 80% thickness reduction. The ratio of Fe:Si on the fragmented Fe-IMCs after 80% reduction is close to 1:1, representing the beta-Al5FeSi. The yield and tensile strengths are increased with increasing reduction rate. On the other hand, the elongation is decreased with the 40% reduction, but slightly increased with the 60% reduction. The elongation is dramatically increased over two times for the specimen of 80% reduction compared with that of the as-cast. Fracture behavior is strongly affected by the morphology and size of Fe-IMCs. The fracture mode is changed from brittle to ductile with the microstructure modification of Fe-IMCs.

AB - In this paper, we discuss the effect of synthesis temperature on the lateral growth of MoS2 thin films in chemical vapor deposition. With increasing temperature, surface coverage with MoS2 triangular islands is significantly improved due to an increase in the density of nuclei and fully continuous MoS2 thin film is grown when the growth temperature reached 800 degrees C. The MoS2 triangular islands grown at the temperature from 650 to 750 degrees C are monolayer and highly crystalline, whereas the large-area continuous film grown at the temperature of 800 degrees C is composed of double-layer or overlapping MoS2 nanosheets. Our research provides that synthesis temperature is the key to growth large area and high quality single crystal MoS2 films.

AB - Sliding bearing maintenance is crucial for reducing the cost and extending the service life. An efficient and practical solution is to coat a restorative agent onto the worn/damaged bearings. Traditional pure-copper (Cu) coating results in a soft surface and poor abrasion resistance. To address this issue, this paper presents a nano-composite repairing coating method. A series of nano-Al/Cu coatings were prepared on the surface of 45 steel by composite electro-brush plating (EBP). Their micro-hardness was examined by a MHV-2000 Vickers hardness tester, and tribological properties by a UMT-2M Micro-friction tester, 3D profiler and SEM. Then, the influence of processing parameters such as nano particle concentration and coating thickness on the micro-hardness of nano-Al/Cu coating was analyzed. The experimental analysis results demonstrate that, when the nano-Al particle concentration in electrolyte was 10 g/L, the micro-hardness of the composite coating was 1.1 times as much as that of pure-Cu coating. When the Al nano-particle concentration in electrolyte was 20 g/L, the micro-hardness of the composite coating reached its maximum value (i.e., 231.6 HV). Compared with the pure-Cu coating, the hardness and wear resistance of the nano-composite coating were increased, and the friction coefficient and wear volume were decreased, because of the grain strengthening and dispersion strengthening. The development in this work may provide a feasible and effective nano-composite EBP method for sliding bearing repair.

AB - Up-conversion phosphors have attracted considerable attention because of their applications in solid-state lasers, optical communications, flat-panel displays, photovoltaic cells, and biological labels. Among them, NaYF4 is reported as one of the most efficient hosts for infrared to visible photon up-conversion of Yb3+ and Er3+ ions. However, a low-temperature method is required for industrial scale fabrication of photonic and optoelectronic devices on flexible organic substrates. In this study, hexagonal beta-NaYF4: 3 mol% Yb3+, 3 mol% Er3+ up conversion phosphor using Ca2+ was prepared by chemical solution method. Then, we synthesized a nanostructured organo-silicon compound from methyl tri methoxysilane and 3-glycidoxy-propyl-trimethoxy-silane. The transmittance of the organo-silicon compound was found to be over 90% in the wavelength range of 400~1500 nm. Then we prepared a fluoride-based phosphor paste by mixing the organo-silicon compound with Na(Ca)YF4:Yb3+, Er3+. Subsequently, this paste was coated on polyethylene terephthalate, followed by heat-treatment at 120 degrees C. The visible emission of the infrared detection card was found to be at 655 nm and 661 nm an excitation wavelength of 980 nm.

AB - The temperature-dependent bandgap of transition metal dichalcogenides (TMDCs, MX2; M = Mo or W; X = S, Se, or Te) is analyzed using the O'Donnell and Chen relation with parameters including the average acoustic phonon energy () and the electron-phonon coupling strength (s). Wider (narrower) tunability of the bandgap results from the larger (smaller) electron-phonon coupling strength for a constant acoustic phonon energy. A 1.5 eV bandgap change was observed for weak electron-phonon coupling (s = 2) as well as with the strong electron-phonon coupling (s = 30). However, the weak electron-phonon coupling leads to a linear decrease in the bandgap energy as a function of temperature above ~85 K while the strong coupling exhibits similar behavior after ~60 K. Narrower (wider) tunability of the bandgap results from the larger (smaller) acoustic phonon energy for a constant electron-phonon coupling strength. The slope of negative entropy of exciton formation is large (small) at lower (higher) temperature. The management of the electron-phonon interaction as well as the average acoustic phonon energy indicates the ability to control the bandgap.

AB - This study was carried out to evaluate the development of microstructures and mechanical properties on friction welded dissimilar materials with a light weight. For this work, Al6063 and Duralumin alloys with a shape of rod were selected as experimental materials, and friction welding was performed under conditions with a rotation speed of 2,000 RPM, a friction load of 12 kgf/cm2 and an upset force of 25 kgf/cm2, respectively. After welding, the microstructural analysis such as the grain boundary characteristic distributions and the formation of intermetallic compounds was analyzed by electron back-scattering diffraction method and transmission electron microscopy, respectively. In addition, the evaluation of mechanical properties on welded materials was conducted by Vickers microhardness and tensile test. As a result, applying the friction welding led to the significant grain refinement from 50 MUm in base material to 2 MUm in welded zone, respectively. In case of mechanical properties, Vickers micro-hardness and tensile strength of the welded material occupied 81% and 96% in fraction relative to the base material, respectively, which was attributable to the formation and growth of intermetallic compounds during the welding.

AB - Influence of Mg contents with the natural aging (NA) time on the two-step aging behavior in Al-Mg-Si alloys is studied. Hardness is gradually increased during NA in the 3M4S, whereas dramatic increase of hardness after NA for 3.6 ks is confirmed in the 9M4S. Similar peak hardness is confirmed between the two-step aged and single aged samples in the 3M4S. It means that there is no negative effect of two-step aging. On the other hand, the peak hardness is decreased for the naturally-aged sample compared with the single aged one in the 9M4S. Formation of Cluster (1) is accelerated by the Mg addition, resulting in the negative effect of two-step aging. Meanwhile, the formation of the precipitates is accelerated by Mg addition during aging at 170 degrees C. The precipitate formed at the peak hardness during aging at 170 degrees C after natural aging for 43.2 ks is identified as the beta" phase based on the high resolution transmission electron microscope observation.

The application is advantageous because it can reduce number of manufacturing processes, and may increase strength by strain aging. If die quenching is realized in forging as well as sheet forming, it may widen industrial applicability further. In this study, Al-Mg-Si alloy AA6061 8 mm-thick billets were reduced 50% in height without cracks by die-quench forging. Supersaturated solid solution was successfully obtained. The die-quenched specimen shows higher hardness with nano precipitates at shorter aging time than the conventional water-quenched specimen.

AB - Molybdenum carbide is an interesting and versatile material, which has important applications in the metal matrix industry as a reinforcement material, as well as in the catalytic field. Though many papers suggest different methodologies for adding cobalt to the carbide structure aiming either to increase catalytic activity or enhancing mechanical proprieties such as ductility, etc. no straightforward evaluation is available. In the present paper two doping methodologies were studied: via solid state mixture of powders and via wet impregnation. Ammonium molybdate [(NH4)2MoO4] and cobalt nitrate [Co(NO3)2.6H2O] were used as starting materials and the doping process was carried out before carburization reaction. Those materials were characterized by FT-IR, SEM, XRF and XRD. The carbo-reduction products' were evaluated on XRD and XRF basis. Doped precursors' evaluation showed that the wet impregnated doped materials presented smaller particle sizes, were more homogeneous and retained more cobalt than the solid state doped ones. However, final products' assessment indicated that the solid state methodology was able to retain a greater dopant percentage according to XRF evaluation, and XRD data indicated a more intrinsic addition of the dopant to the carbide structure. In addition, no significant changes on particle size could be attributed to any of the methodologies, both producing Mo2C of approximately 30 nm.

AB - Methionine gamma-lyase is a pyridoxal 5'-phosphate dependent tetramer that catalyzes the alpha,gamma-elimination of methionine in ammonia, methanethiol and alpha-ketobutyrate. MGL catalytic power has been exploited as a therapeutic strategy to reduce the viability of cancer cells or bacteria. In order to obtain a stable enzyme to be delivered at the site of action, MGL can be encapsulated in a variety of matrices. As a reference encapsulation strategy we have prepared MGL nanoporous wet silica gels. Immobilized MGL gels were characterized with regards to activity, stability, absorption, circular dichroism and fluorescence properties and compared with soluble MGL. We found that MGL gels exhibit (i) spectroscopic properties very similar to MGL in solution, (ii) a higher stability with respect to the soluble enzyme and (iii) catalytic activity six-fold lower than in solution. These findings prove that MGL encapsulation is a suitable strategy for therapeutic applications.

AB - The objective of this study was to fabricate an Al metal matrix composite strengthened by nanosized Al3Ti particles via double mechanical alloying process. Several Al-xTi alloys were fabricated, including Al-12%Ti, Al-15%Ti, and Al-12%Ti 1%Y2O3. The lattice parameter of as-milled state was calculated to be 4.0485 A; after a milling time of 540 min, it was 4.0401 A. This decrease was induced by Ti solutionizing into the Al matrix. The equivalent size of a coarse Al3Ti particle was 200-500 nm after the heat treatment; however, the particles were uniformly distributed and were refined through the MA2 process. The particle size of a Al3Ti phase was 30 nm or less, and the particles were uniformly distributed. These particles remained in a fine state in the matrix without growth and coarsening, even after the hot extrusion process. The microstructure of hot extruded alloys consisted of a uniform distribution of Al3Ti particles and other dispersoids in the Al matrix.

AB - This study evaluated the effect of acid etching on surface characteristics, flexural strength and osteoblast cell response of glass-infiltrated zirconia. Zirconia specimens were divided into six groups: untreated zirconia (Z); glass infiltrated zirconia (ZG); glass-infiltrated and sandblasted zirconia (ZGS); glass-infiltrated, sandblasted and 5 min acid-etched zirconia (ZGS-E5); glassinfiltrated, sandblasted and 15 min acid-etched zirconia (ZGS-E15); glass infiltrated, sandblasted and 25 min acid-etched zirconia (ZGS-E25). Surface roughness, biaxial flexural strength and MC3T3-E1 cell proliferation were evaluated. When increasing etching time, surface roughness significantly increased while flexural strength decreased. Cell proliferation rate at day 3 on group ZGS-E15 and ZGS-E25 was significantly higher than that of other groups. Surface roughness and flexural strength of glass-infiltrated zirconia can be controlled by adjusting etching time. Rough surface made by acid etching following glass infiltration significantly enhanced osteoblast cell response. Glass infiltration improved strength of zirconia but severe acid etching slightly reduced strength of zirconia. PMID- 29448751 TI - Effect of Zn on Pore Characteristics in Lotus-Type Porous Cu. AB - The effect of Zn on pore characteristics in lotus-type porous Cu alloy was investigated. The lotustype porous Cu-Zn alloys were fabricated with Zn content from 0.01 to 0.1 at% by the centrifugal casting method. The results demonstrated that the porosity was rarely affected by Zn content. However, the average pore diameter and pore number density of the lotus type porous Cu-Zn alloys were significantly affected by the Zn content. The average pore diameter decreased as the Zn content increased up to 0.01 at%, and then increased as the Zn content increased up to 0.1 at%. In contrast, the variations in the pore number density of the lotus-type porous Cu-Zn alloys showed the reversed tendency with respect to that of the average pore diameter. The increase in heterogeneous nucleation sites for pores attributed to the decreased average pore diameter and the increased pore number density.

PMID- 29448753 TI - Tailored Pt/TiO2 Photocatalyst with Controllable Phase Prepared via a Modified Sol-Gel Process for Dye Degradation. AB - Pt/TiO2 photocatalysts with controllable phase were successfully prepared by controlling the hydrolysis pH values during the sol-gel process followed by Pt photodeposition. The effect of different phases of TiO2 coated with Pt on the catalytic properties and the photocatalytic activities were also investigated. The characterization results of the synthesis of TiO2 under neutral/alkaline and acidic conditions during the hydrolysis step revealed the facile formation of the anatase phase and the brookite/rutile phase, respectively. Pt/TiO2 photocatalysts prepared at hydrolysis pH values of 2, 7, and 10 had different TiO2 phase compositions, but the main crystalline sizes of the photocatalysts were all close to 6 nm. The Pt/TiO2 particles prepared at various hydrolysis pH values were all spheroidal. The PL results indicated that the anatase/rutile junction of a Pt/TiO2 sample had a lower recombination rate than did the anatase phase of Pt/TiO2 owing to the longer recombination pathway. However, the anatase phase of Pt/TiO2 exhibited better degradation ability than the anatase/rutile junction of Pt/TiO2, and the degradation rate decreased with a decrease in the anatase composition of TiO2, indicating that anatase composition in the Pt/TiO2 system played an important role of enhancing the photocatalytic degradation of Acid Red 1 dye.

AB - Recyclable magnetites with thioureido group (poly-allyl-thiourea/oleic acid/magnetite, PAT-adsorbent) and amine functional group (ethylenediamine/methyl methacrylate/oleic acid/magnetite, EDA-adsorbent) were synthesized by modifying magnetite with oleic acid, methyl methacrylate, allyl thiourea and ethylenediamine. PAT-adsorbent and EDA-adsorbent were used and compared for adsorption of copper ions in a batch system due to the existence of amino group ( NH2) both on thioureido group and amine functional group. The kinetics of both PAT-adsorbent and EDA-adsorbent were evaluated utilizing pseudo-first-order and pseudo-second-order kinetic models. The equilibrium data was analyzed and compared using the Langmuir and Freundlich isotherm models. The maximum adsorption capacity (Qm) of PAT-adsorbent (19.126 mg g-1) was higher than that of EDA-adsorbent (7.096 mg g-1). As compared to EDA-adsorbent the magnetic adsorbent (PAT-adsorbent) with good desorption performance (>85% desorption efficiency) and easily reuse (>85% recovery by magnetic force) was the important factors for its potential practical application.

AB - The present study investigates the effectiveness of the photocatalytic degradation of humic acid (HA) in aqueous suspensions. Initial batch scale experiments and tests performed using the Continuous Flow Photoreactor have enabled the close inspection of the performance of the photocatalysts nano TiO2, and nano ZnO dispersions. These photocatalysts were used in aqueous dispersions employing medium-pressure mercury-vapour lamps emitting UV-A (lambda = 400 nm) and UV-C (lambda = 250 nm). Moreover, glass microfibre filters were embedded and coated with Laponite RD (synthetic polycrystalline swelling clay) in order to produce catalytic films to be used in small scale experiments to remove HA through filtration. The findings of this study shows that the HA adsorb highly onto the ZnO and TiO2 surface thus initiating photodegradation, the effectiveness of which steadily increases with irradiation time along with an increase in the biodegradability of HA. PMID- 29448756 TI - Ductile Crack Initiation Criterion with Mismatched Weld Joints Under Dynamic Loading Conditions. AB - Brittle failure of high toughness steel structures tends to occur after ductile crack initiation/propagation. Damages to steel structures were reported in the Hanshin Great Earthquake. Several brittle failures were observed in beam-to column connection zones with geometrical discontinuity. It is widely known that triaxial stresses accelerate the ductile fracture of steels. The study examined the effects of geometrical heterogeneity and strength mismatches (both of which elevate plastic constraints due to heterogeneous plastic straining) and loading rate on critical conditions initiating ductile fracture. This involved applying the two-parameter criterion (involving equivalent plastic strain and stress triaxiality) to estimate ductile cracking for strength mismatched specimens under static and dynamic tensile loading conditions. Ductile crack initiation testing was conducted under static and dynamic loading conditions using circumferentially notched specimens (Charpy type) with/without strength mismatches. The results indicated that the condition for ductile crack initiation using the two parameter criterion was a transferable criterion to evaluate ductile crack initiation independent of the existence of strength mismatches and loading rates.

AB - Single-phase cubic (FCC) vanadium nitride (VN) coatings with different preferential orientations and residual stresses were obtained as a function of ICP power. Microstructural, crystallographic and mechanical characterizations were performed by FE-SEM, AFM, XRD and nanoindentation. The results show that ICP has significant effects on coating's microstructure, structural and mechanical properties of VN coatings. With an increase in ICP power, coating microstructure evolved from a porous columnar structure to a highly dense one. Single-phase cubic (FCC) VN coatings with different preferential orientations and residual stresses were obtained as a function of ICP power. Average crystal grain sizes of single phase cubic VN coatings were decreased from 10.1 nm to 4.0 nm with an increase in ICP power. Maximum hardness of 28.2 GPa was obtained for the coatings deposited at ICP power of 200 W.

AB - Lotus-type porous Cu-Fe and Cu-Cr with long cylindrical pores was fabricated by centrifugal casting under hydrogen atmosphere and the effect of alloying elements on pore characteristics of lotus-type porous Cu was investigated. For the lotus type porous Cu-Fe alloy, the porosity slightly decreased and the average pore diameter slightly increased with increasing Fe content. For the lotus-type porous Cu-Cr alloy, the porosity sharply decreased and the average pore diameter drastically increased with an increase in the Cr content. From these results, it was found that the pore evolution and growth are affected by alloying element and this leads to the change in the pore characteristics of lotus-type porous Cu-Fe and Cu-Cr alloys.

Therefore, many research groups have studied improvement of c-BN synthesis method and deposition processes due to many potential applications. In this paper, we show that the adhesion property of c-BN layer system can be improved by deposing multi c-BN layers. The multi c-BN layers were deposited by r.f (13.56 MHz) diode sputtering apparatus on cemented carbide tool substrates with a TiAlN adhesion layer. For industrial applications, we performed turning and milling experiments under dry and high speed cutting conditions. In this multi c-BN layer system, the lifetime of the tool is affected by the physical properties of the substrate and coated layers such as substrate grain size, thickness of the TiAlN and first c-BN layer and the total number of c-BN layers in this system. Mostly, fine grain size substrates showed longer lifetimes of over 4 times than raw one. In the turning performance, mono TiAlN layer systems were about two times lower lifetime than mono and multi c-BN layer system, moreover, we could be improved adhesion property for milling performance on tool substrates with binary multi c-BN layer systems under dry and high speed cutting conditions. The new application results of the multi c-BN layer system confirm that the high potential of c-BN coatings on cutting tools.

AB - Parts of Salvia species such as its flowers and leaves are currently used as a culinary herb and for some medicinal applications. To distinguish the different sage extracts it is necessary to analyze their individual chemical compositions. Their characteristic compounds might be established as markers to differentiate between sage flowers and leaf extracts or to determine the manufacturing technology and storage conditions. Tri-p-coumaroylspermidine can be detected only in flowers and has been described here for Salvia and Lavandula species for the first time. Markers for oxidation processes are the novel compounds salviquinone A and B, which were generated from carnosol by exposure to oxygen. Caffeic acid ethyl ester was established as an indirect marker for the usage of ethanol as extraction solvent. The compounds were identified by LC-QTOF-HRESIMS, LC-MS, NMR, IR, and single-crystal X-ray diffraction after isolation by semipreparative HPLC. Furthermore, sage flower resin showed interesting antibacterial in vitro activities against Gram-positive and Gram-negative bacteria.

PMID- 29448766 TI - Escape rate for nonequilibrium processes dominated by strong non-detailed balance force. AB - Quantifying the escape rate from a meta-stable state is essential to understand a wide range of dynamical processes. Kramers' classical rate formula is the product of an exponential function of the potential barrier height and a pre-factor related to the friction coefficient. Although many applications of the rate formula focused on the exponential term, the prefactor can have a significant effect on the escape rate in certain parameter regions, such as the overdamped limit and the underdamped limit. There have been continuous interests to understand the effect of non-detailed balance on the escape rate; however, how the prefactor behaves under strong non-detailed balance force remains elusive. In this work, we find that the escape rate formula has a vanishing prefactor with decreasing friction strength under the strong non-detailed balance limit. We both obtain analytical solutions in specific examples and provide a derivation for more general cases. We further verify the result by simulations and propose a testable experimental system of a charged Brownian particle in electromagnetic field. Our study demonstrates that a special care is required to estimate the effect of prefactor on the escape rate when non-detailed balance force dominates. PMID- 29448767 TI - Crystal nucleation in sedimenting colloidal suspensions. AB - Homogeneous crystal nucleation from a metastable hard-sphere colloidal liquid has been extensively studied in simulations and experiments. A 12 order of magnitude difference between simulated and experimental nucleation rates is observed, the origin of which remains a puzzle. Here, we experimentally study crystal nucleation at the single particle level in suspensions of hard-sphere-like colloids under the influence of sedimentation. We find that sedimentation significantly enhances the nucleation rate, but contrary to what was previously thought, this is not due to simple density fluctuations, as the nucleation barriers become independent of the local density in a sedimentating fluid. Instead, we find an enhancement of the local dynamics, which suggests that local convective cells are responsible for shear-enhanced crystallization at low volume fractions. PMID- 29448768 TI - Mobility and settling rate of agglomerates of polydisperse nanoparticles. AB - Agglomerate settling impacts nanotoxicology and nanomedicine as well as the stability of engineered nanofluids. Here, the mobility of nanostructured fractal like SiO2 agglomerates in water is investigated and their settling rate in infinitely dilute suspensions is calculated by a Brownian dynamics algorithm tracking the agglomerate translational and rotational motion. The corresponding friction matrices are obtained using the HYDRO++ algorithm [J. G. de la Torre, G. del Rio Echenique, and A. Ortega, J. Phys. Chem. B 111, 955 (2007)] from the Kirkwood-Riseman theory accounting for hydrodynamic interactions of primary particles (PPs) through the Rotne-Prager-Yamakawa tensor, properly modified for polydisperse PPs. Agglomerates are generated by an event-driven method and have constant mass fractal dimension but varying PP size distribution, mass, and relative shape anisotropy. The calculated diffusion coefficient from HYDRO++ is used to obtain the agglomerate mobility diameter dm and is compared with that from scaling laws for fractal-like agglomerates. The ratio dm/dg of the mobility diameter to the gyration diameter of the agglomerate decreases with increasing relative shape anisotropy. For constant dm and mean dp, the agglomerate settling rate, us, increases with increasing PP geometric standard deviation sigmap,g (polydispersity). A linear relationship between us and agglomerate mass to dm ratio, m/dm, is revealed and attributed to the fast Brownian rotation of such small and light nanoparticle agglomerates. An analytical expression for the us of agglomerates consisting of polydisperse PPs is then derived, us=1 rhofrhopg3piMUmdm (rhof is the density of the fluid, rhop is the density of PPs, MU is the viscosity of the fluid, and g is the acceleration of gravity), valid for agglomerates for which the characteristic rotational time is considerably shorter than their settling time. Our calculations demonstrate that the commonly made assumption of monodisperse PPs underestimates us by a fraction depending on sigmap,g and agglomerate mass mobility exponent. Simulations are in excellent agreement with deposition rate measurements of fumed SiO2 agglomerates in water.

AB - The formation of gas bubbles presents a frequent challenge to microfluidic operations, for which fluids are geometrically confined to a microscale space. Here, to understand the mechanism of nucleating gas bubbles in microfluidic devices, we investigate the formation and stability of nanobubbles in confined solutions. Our molecular dynamics simulations show that while pinning of the contact line is a prerequisite for the stability of surface nanobubbles in open systems that can exchange gas with surrounding environment, in confined solutions, stable nanobubbles can exist even without pinning. In supersaturated condition, stable bubbles can be found in confined solutions with acute or obtuse contact angle, depending on the substrate hydrophobicity. We also demonstrate that when open to the bulk solution, the stable nanobubbles in closed systems would become unstable unless both supersaturation and pinning of the contact line are satisfied. Our results not only shed light on the design of novel heterogeneous surfaces for generating nanobubbles in confined space with controllable shape and stability but also address the crucial effect of gas exchange with the surroundings in determining the stability of nanobubbles.

AB - Steric or attractive interactions among reactants or between reactants and inert crowders can substantially influence the total rate of a diffusion-influenced reaction in the liquid phase. However, the role of the product species, which has typically different physical properties than the reactant species, has been disregarded so far. Here we study the effects of reactant-product and product product interactions as well as asymmetric diffusion properties on the rate of diffusion-controlled reactions in the classical Smoluchowski-setup for chemical transformations at a perfect catalytic sphere. For this, we solve the diffusion equation with appropriate boundary conditions coupled by a mean-field approach on the second virial level to account for the particle interactions. We find that all particle spatial distributions and the total rate can change significantly, depending on the diffusion and interaction properties of the accumulated products. Complex competing and self-regulating (homeostatic) or self-amplifying effects are observed for the system, leading to both decrease and increase in the rates, as the presence of interacting products feeds back to the reactant flux and thus the rate with which the products are generated. PMID- 29448771 TI - Dark states and delocalization: Competing effects of quantum coherence on the efficiency of light harvesting systems. AB - Natural light harvesting systems exploit electronic coupling of identical chromophores to generate efficient and robust excitation transfer and conversion. Dark states created by strong coupling between chromophores in the antenna structure can significantly reduce radiative recombination and enhance energy conversion efficiency. Increasing the number of the chromophores increases the number of dark states and the associated enhanced energy conversion efficiency yet also delocalizes excitations away from the trapping center and reduces the energy conversion rate. Therefore, a competition between dark state protection and delocalization must be considered when designing the optimal size of a light harvesting system. In this study, we explore the two competing mechanisms in a chain-structured antenna and show that dark state protection is the dominant mechanism, with an intriguing dependence on the parity of the number of chromophores. This dependence is linked to the exciton distribution among eigenstates, which is strongly affected by the coupling strength between chromophores and the temperature. Combining these findings, we propose that increasing the coupling strength between the chromophores can significantly increase the power output of the light harvesting system.

PMID- 29448773 TI - A theoretical and experimental benchmark study of core-excited states in nitrogen. AB - The high resolution near edge X-ray absorption fine structure spectrum of nitrogen displays the vibrational structure of the core-excited states. This makes nitrogen well suited for assessing the accuracy of different electronic structure methods for core excitations. We report high resolution experimental measurements performed at the SOLEIL synchrotron facility. These are compared with theoretical spectra calculated using coupled cluster theory and algebraic diagrammatic construction theory. The coupled cluster singles and doubles with perturbative triples model known as CC3 is shown to accurately reproduce the experimental excitation energies as well as the spacing of the vibrational transitions. The computational results are also shown to be systematically improved within the coupled cluster hierarchy, with the coupled cluster singles, doubles, triples, and quadruples method faithfully reproducing the experimental vibrational structure. PMID- 29448774 TI - Incorporating extrinsic noise into the stochastic simulation of biochemical reactions: A comparison of approaches. AB - The stochastic simulation algorithm (SSA) has been widely used for simulating biochemical reaction networks. SSA is able to capture the inherently intrinsic noise of the biological system, which is due to the discreteness of species population and to the randomness of their reciprocal interactions. However, SSA does not consider other sources of heterogeneity in biochemical reaction systems, which are referred to as extrinsic noise. Here, we extend two simulation approaches, namely, the integration-based method and the rejection-based method, to take extrinsic noise into account by allowing the reaction propensities to vary in time and state dependent manner. For both methods, new efficient implementations are introduced and their efficiency and applicability to biological models are investigated. Our numerical results suggest that the rejection-based method performs better than the integration-based method when the extrinsic noise is considered. PMID- 29448775 TI - Molecular simulation of steady-state evaporation and condensation in the presence of a non-condensable gas. AB - Using molecular dynamics simulations, we study evaporation and condensation of fluid Ar in the presence of a non-condensable Ne gas in a nanochannel. The evaporation and condensation are driven by the temperature difference, DeltaTL, between the evaporating and condensing liquid surfaces. The steady-state evaporation and condensation fluxes (JMD) are also affected by the Ne concentration, rhoNe, and the nanochannel length. We find that across a wide range of DeltaTL and rhoNe, JMD is in good agreement with the prediction from Stefan's law and from Schrage relationships. Furthermore, for DeltaTL less than ~20% of the absolute average temperature, we find that both steady-state heat and mass fluxes are proportional to DeltaTL. This allows us to determine the interfacial resistance to the heat and mass transfer and compare it with the corresponding resistances in the gas phase. In this context, we derive an analytical expression for the effective thermal conductivity of the gas region in the nanochannel and the mass transport interfacial resistance equivalent length, i.e., the length of the nanochannel for which the resistance to the mass flow is the same as the interfacial resistance to the mass flow. PMID- 29448776 TI - Employing general fit-bases for construction of potential energy surfaces with an adaptive density-guided approach. AB - We present an approach to treat sets of general fit-basis functions in a single uniform framework, where the functional form is supplied on input, i.e., the use of different functions does not require new code to be written. The fit-basis functions can be used to carry out linear fits to the grid of single points, which are generated with an adaptive density-guided approach (ADGA). A non-linear conjugate gradient method is used to optimize non-linear parameters if such are present in the fit-basis functions. This means that a set of fit-basis functions with the same inherent shape as the potential cuts can be requested and no other choices with regards to the fit-basis functions need to be taken. The general fit basis framework is explored in relation to anharmonic potentials for model systems, diatomic molecules, water, and imidazole. The behaviour and performance of Morse and double-well fit-basis functions are compared to that of polynomial fit-basis functions for unsymmetrical single-minimum and symmetrical double-well potentials. Furthermore, calculations for water and imidazole were carried out using both normal coordinates and hybrid optimized and localized coordinates (HOLCs). Our results suggest that choosing a suitable set of fit-basis functions can improve the stability of the fitting routine and the overall efficiency of potential construction by lowering the number of single point calculations required for the ADGA. It is possible to reduce the number of terms in the potential by choosing the Morse and double-well fit-basis functions. These effects are substantial for normal coordinates but become even more pronounced if HOLCs are used. PMID- 29448777 TI - Laplace transformed MP2 for three dimensional periodic materials using stochastic orbitals in the plane wave basis and correlated sampling. AB - We present an implementation and analysis of a stochastic high performance algorithm to calculate the correlation energy of three-dimensional periodic systems in second-order Moller-Plesset perturbation theory (MP2). In particular we measure the scaling behavior of the sample variance and probe whether this stochastic approach is competitive if accuracies well below 1 meV per valence orbital are required, as it is necessary for calculations of adsorption, binding, or surface energies. The algorithm is based on the Laplace transformed MP2 (LTMP2) formulation in the plane wave basis. The time-dependent Hartree-Fock orbitals, appearing in the LTMP2 formulation, are stochastically rotated in the occupied and unoccupied Hilbert space. This avoids a full summation over all combinations of occupied and unoccupied orbitals, as inspired by the work of Neuhauser, Rabani, and Baer [J. Chem. Theory Comput. 9, 24 (2013)]. Additionally, correlated sampling is introduced, accelerating the statistical convergence significantly. PMID- 29448778 TI - Remarks on the chemical Fokker-Planck and Langevin equations: Nonphysical currents at equilibrium. AB - The chemical Langevin equation and the associated chemical Fokker-Planck equation are well-known continuous approximations of the discrete stochastic evolution of reaction networks. In this work, we show that these approximations suffer from a physical inconsistency, namely, the presence of nonphysical probability currents at the thermal equilibrium even for closed and fully detailed-balanced kinetic schemes. An illustration is given for a model case. PMID- 29448779 TI - Flow of quasi-two dimensional water in graphene channels. AB - When liquids confined in slit channels approach a monolayer, they become two dimensional (2D) fluids. Using molecular dynamics simulations, we study the flow of quasi-2D water confined in slit channels featuring pristine graphene walls and graphene walls with hydroxyl groups. We focus on to what extent the flow of quasi 2D water can be described using classical hydrodynamics and what are the effective transport properties of the water and the channel. First, the in-plane shearing of quasi-2D water confined between pristine graphene can be described using the classical hydrodynamic equation, and the viscosity of the water is ~50% higher than that of the bulk water in the channel studied here. Second, the flow of quasi-2D water around a single hydroxyl group is perturbed at a position of tens of cluster radius from its center, as expected for low Reynolds number flows. Even though water is not pinned at the edge of the hydroxyl group, the hydroxyl group screens the flow greatly, with a single, isolated hydroxyl group rendering drag similar to ~90 nm2 pristine graphene walls. Finally, the flow of quasi-2D water through graphene channels featuring randomly distributed hydroxyl groups resembles the fluid flow through porous media. The effective friction factor of the channel increases linearly with the hydroxyl groups' area density up to 0.5 nm-2 but increases nonlinearly at higher densities. The effective friction factor of the channel can be fitted to a modified Carman equation at least up to a hydroxyl area density of 2.0 nm-2. These findings help understand the liquid transport in 2D material-based nanochannels for applications including desalination. PMID- 29448781 TI - Anion photoelectron spectroscopy of deprotonated indole and indoline. AB - Anion photoelectron spectra of deprotonated indole have been obtained utilizing several photon energies. The slow electron velocity-map imaging spectrum of indolide allows for the determination of the electron affinity (EA) of indolyl, 2.4315 +/- 0.0017 eV. The equilibrium geometry of indolide was shown to minimally distort upon photodetachment with only ring distortion vibrational modes of A' symmetry becoming significantly excited. Photoelectron spectra of indolide accessing the electronic ground state of indolyl displayed a photon energy dependence due to electron autodetachment. Combining the EA of indolyl with the previous work studying the dissociation energy of H-indolyl allows for a new independent measure of DeltaacidH0KoN-Hindole <= 348.7 kcal/mol, which improves the previous measurement of the gas phase acidity. The anion photoelectron spectrum of deprotonated indoline consisted of a featureless broad band extending from ~1.3 eV to 1.7 eV electron binding energy. The congested nature of the spectrum is likely due to the presence of multiple isomers of deprotonated indoline, including ring-opened structures. PMID- 29448780 TI - Semiexperimental and mass-dependent structures by the mixed regression method: Accurate equilibrium structure and failure of the Kraitchman method for ethynylcyclohexane. AB - The mixed regression method for determination of molecular structures is reviewed and applied to the investigation of ethynylcyclohexane, using both semiexperimental and mass-dependent methods. This methodology provides an efficient and computationally affordable route to obtain accurate molecular reference data, preventing ill-conditioning in the structural least-squares determinations from experimental rotational constants. New supersonic-jet microwave measurements are reported to obtain inertial data for the axial and equatorial species of ethynylcyclohexane, together with all 13C isotopologues of the equatorial form. The semiexperimental equilibrium (reSE) and mass-dependent (rm(2)) structures of the molecule are compared with high-level ab initio optimizations, showing that both methods deliver compatible structures with accuracies of about 0.002 A for bond lengths and 0.2 degrees for bond angles. We confirm that dependable predicates can be obtained for a large variety of bonds. Finally, we verify that the substitution method completely fails to determine a reliable structure for the title compound. PMID- 29448782 TI - Pressure control in interfacial systems: Atomistic simulations of vapor nucleation. AB - A large number of phenomena of scientific and technological interest involve multiple phases and occur at constant pressure of one of the two phases, e.g., the liquid phase in vapor nucleation. It is therefore of great interest to be able to reproduce such conditions in atomistic simulations. Here we study how popular barostats, originally devised for homogeneous systems, behave when applied straightforwardly to heterogeneous systems. We focus on vapor nucleation from a super-heated Lennard-Jones liquid, studied via hybrid restrained Monte Carlo simulations. The results show a departure from the trends predicted for the case of constant liquid pressure, i.e., from the conditions of classical nucleation theory. Artifacts deriving from standard (global) barostats are shown to depend on the size of the simulation box. In particular, for Lennard-Jones liquid systems of 7000 and 13 500 atoms, at conditions typically found in the literature, we have estimated an error of 10-15 kBT on the free-energy barrier, corresponding to an error of 104-106 s-1sigma-3 on the nucleation rate. A mechanical (local) barostat is proposed which heals the artifacts for the considered case of vapor nucleation. PMID- 29448783 TI - Molecular dynamics simulation of ion mobility in gases. AB - A force field molecular dynamics method is developed to directly simulate ion drift in buffer gases driven by an electric field. The ion mobility and collision cross sections (CCSs) with relevance to ion mobility spectrometry can be obtained from the simulated drift velocity in high-density buffer gases (pressure ~50 bars) and high electric fields (~107 V/m). Compared to trajectory methods, the advantage of the molecular dynamics method is that it can simultaneously sample the internal dynamic motions of the ion and the ion-gas collisions. For ions with less than 100 atoms, the simulated collision cross section values can be converged to within +/-1%-2% by running a 100 ns simulation for 5-19 h using one computer core. By using a set of element-based Lennard-Jones parameters that are not tuned for different atomic types in different molecules, the simulated collision cross sections for 15 small molecular ions (number of atoms ranging from 17 to 85, mass ranging from 74.1 to 609.4 g/mol) are consistent with experimental values: the mean unsigned error is 2.6 A2 for He buffer gas and 4.4 A2 for N2 buffer gas. The sensitivity of the simulated CCS values to random diffusion, drift velocity, electric field strength, temperature, and buffer gas density is examined. PMID- 29448784 TI - Dirac cone in two dimensional bilayer graphene by intercalation with V, Nb, and Ta transition metals. AB - Bilayer graphene (BLG) is a semiconductor whose band gap and properties can be tuned by various methods such as doping or applying gate voltage. Here, we show how to tune electronic properties of BLG by intercalation of transition metal (TM) atoms between two monolayer graphene (MLG) using a novel dispersion corrected first-principle density functional theory (DFT) approach. We intercalated V, Nb, and Ta atoms between two MLG. We found that the symmetry, the spin, and the concentration of TM atoms in BLG-intercalated materials are the important parameters to control and to obtain a Dirac cone in their band structures. Our study reveals that the BLG intercalated with one vanadium (V) atom, BLG-1V, has a Dirac cone at the K-point. In all the cases, the present DFT calculations show that the 2pz sub-shells of C atoms in graphene and the 3dyz sub shells of the TM atoms provide the electron density near the Fermi energy level (EF) which controls the material properties. Thus, we show that out-of-plane atoms can influence in-plane electronic densities in BLG and enumerate the conditions necessary to control the Dirac point. This study offers insight into the physical properties of 2D BLG intercalated materials and presents a new strategy for controlling the electronic properties of BLG through TM intercalation by varying the concentration and spin arrangement of the metals resulting in various conducting properties, which include: metal, semi-metal and semiconducting states. PMID- 29448785 TI - MC-PDFT can calculate singlet-triplet splittings of organic diradicals. AB - The singlet-triplet splittings of a set of diradical organic molecules are calculated using multiconfiguration pair-density functional theory (MC-PDFT), and the results are compared with those obtained by Kohn-Sham density functional theory (KS-DFT) and complete active space second-order perturbation theory (CASPT2) calculations. We found that MC-PDFT, even with small and systematically defined active spaces, is competitive in accuracy with CASPT2, and it yields results with greater accuracy and precision than Kohn-Sham DFT with the parent functional. MC-PDFT also avoids the challenges associated with spin contamination in KS-DFT. It is also shown that MC-PDFT is much less computationally expensive than CASPT2 when applied to larger active spaces, and this illustrates the promise of this method for larger diradical organic systems. PMID- 29448786 TI - Structural relaxation and highly viscous flow. AB - The highly viscous flow is due to thermally activated Eshelby transitions which transform a region of the undercooled liquid to a different structure with a different elastic misfit to the viscoelastic surroundings. A self-consistent determination of the viscosity in this picture explains why the average structural relaxation time is a factor of eight longer than the Maxwell time. The physical reason for the short Maxwell time is the very large contribution of strongly strained inherent states to the fluidity (the inverse viscosity). At the Maxwell time, the viscous no-return processes coexist with the back-and-forth jumping retardation processes.

AB - The exactly analytic gradient is derived and implemented for the fragment molecular orbital (FMO) method combined with density-functional tight-binding (DFTB) using adaptive frozen orbitals. The response contributions which arise from freezing detached molecular orbitals on the border between fragments are computed by solving Z-vector equations. The accuracy of the energy, its gradient, and optimized structures is verified on a set of representative inorganic materials and polypeptides. FMO-DFTB is applied to optimize the structure of a silicon nano-wire, and the results are compared to those of density functional theory and experiment. FMO accelerates the DFTB calculation of a boron nitride nano-ring with 7872 atoms by a factor of 406. Molecular dynamics simulations using FMO-DFTB applied to a 10.7 MUm chain of boron nitride nano-rings, consisting of about 1.2 * 106 atoms, reveal the rippling and twisting of nano rings at room temperature.

AB - Events from the sequential and concerted modes of the fragmentation of OCS3+ that result in coincident detection of fragments C+, O+, and S+ have been separated using a newly proposed representation. An ion beam of 1.8 MeV Xe9+ is used to make the triply charged molecular ion, with the fragments being detected by a recoil ion momentum spectrometer. By separating events belonging exclusively to the sequential mode of breakup, the electronic states of the intermediate molecular ion (CO2+ or CS2+) involved are determined, and from the kinetic energy release spectra, it is shown that the low lying excited states of the parent OCS3+ are responsible for this mechanism. An estimate of branching ratios of events coming from sequential versus concerted mode is presented. PMID- 29448790 TI - Benchmarking several van der Waals dispersion approaches for the description of intermolecular interactions. AB - Seven methods, including three van der Waals density functionals (vdW-DFs) and four different variants of the Tkatchenko-Scheffler (TS) methods, are tested on the A24, L7, and Taylor et al.'s "blind" test sets. It is found that for these systems, the vdW-DFs perform better that the TS methods. In particular, the vdW DF-cx functional gives binding energies that are the closest to the reference values, while the many-body correction of TS does not always lead to an improvement in the description of molecular systems. In light of these results, several directions for further improvements to describe van der Waals interactions are discussed. PMID- 29448791 TI - Energy decomposition analysis for exciplexes using absolutely localized molecular orbitals. AB - An energy decomposition analysis (EDA) scheme is developed for understanding the intermolecular interaction involving molecules in their excited states. The EDA utilizes absolutely localized molecular orbitals to define intermediate states and is compatible with excited state methods based on linear response theory such as configuration interaction singles and time-dependent density functional theory. The shift in excitation energy when an excited molecule interacts with the environment is decomposed into frozen, polarization, and charge transfer contributions, and the frozen term can be further separated into Pauli repulsion and electrostatics. These terms can be added to their counterparts obtained from the ground state EDA to form a decomposition of the total interaction energy. The EDA scheme is applied to study a variety of systems, including some model systems to demonstrate the correct behavior of all the proposed energy components as well as more realistic systems such as hydrogen-bonding complexes (e.g., formamide water, pyridine/pyrimidine-water) and halide (F-, Cl-)-water clusters that involve charge-transfer-to-solvent excitations. PMID- 29448792 TI - Nanoscale hydrodynamics near solids. AB - Density Functional Theory (DFT) is a successful and well-established theory for the study of the structure of simple and complex fluids at equilibrium. The theory has been generalized to dynamical situations when the underlying dynamics is diffusive as in, for example, colloidal systems. However, there is no such a clear foundation for Dynamic DFT (DDFT) for the case of simple fluids in contact with solid walls. In this work, we derive DDFT for simple fluids by including not only the mass density field but also the momentum density field of the fluid. The standard projection operator method based on the Kawasaki-Gunton operator is used for deriving the equations for the average value of these fields. The solid is described as featureless under the assumption that all the internal degrees of freedom of the solid relax much faster than those of the fluid (solid elasticity is irrelevant). The fluid moves according to a set of non-local hydrodynamic equations that include explicitly the forces due to the solid. These forces are of two types, reversible forces emerging from the free energy density functional, and accounting for impenetrability of the solid, and irreversible forces that involve the velocity of both the fluid and the solid. These forces are localized in the vicinity of the solid surface. The resulting hydrodynamic equations should allow one to study dynamical regimes of simple fluids in contact with solid objects in isothermal situations.

AB - Photodetachment of the ClH2O- anion is investigated using full-dimensional quantum mechanics on accurate potential energy surfaces of both the anion and neutral species. Detailed analysis of the photoelectron spectrum and the corresponding wavefunctions reveals that the photodetachment leads to, in the product channel of the exothermic HCl + OH -> Cl + H2O reaction, the formation of numerous Feshbach resonances due apparently to slow energy transfer from H2O vibrational modes to the dissociation coordinate. These long-lived resonances can be grouped into two broad peaks in the low-resolution photoelectron spectrum, which is in good agreement with available experiments, and they are assigned to the ground and first excited OH stretching vibrational manifolds of H2O complexed with Cl. In addition, effects of isotope substitution on the photoelectron spectrum were small. Finally, photodetachment of the vibrationally excited ClH2O- in the ionic hydrogen bond mode is found to lead to Feshbach resonances with higher stretching vibrational excitations in H2O. PMID- 29448794 TI - Short-time dynamics of lysozyme solutions with competing short-range attraction and long-range repulsion: Experiment and theory. AB - Recently, atypical static features of microstructural ordering in low-salinity lysozyme protein solutions have been extensively explored experimentally and explained theoretically based on a short-range attractive plus long-range repulsive (SALR) interaction potential. However, the protein dynamics and the relationship to the atypical SALR structure remain to be demonstrated. Here, the applicability of semi-analytic theoretical methods predicting diffusion properties and viscosity in isotropic particle suspensions to low-salinity lysozyme protein solutions is tested. Using the interaction potential parameters previously obtained from static structure factor measurements, our results of Monte Carlo simulations representing seven experimental lysoyzme samples indicate that they exist either in dispersed fluid or random percolated states. The self consistent Zerah-Hansen scheme is used to describe the static structure factor, S(q), which is the input to our calculation schemes for the short-time hydrodynamic function, H(q), and the zero-frequency viscosity eta. The schemes account for hydrodynamic interactions included on an approximate level. Theoretical predictions for H(q) as a function of the wavenumber q quantitatively agree with experimental results at small protein concentrations obtained using neutron spin echo measurements. At higher concentrations, qualitative agreement is preserved although the calculated hydrodynamic functions are overestimated. We attribute the differences for higher concentrations and lower temperatures to translational-rotational diffusion coupling induced by the shape and interaction anisotropy of particles and clusters, patchiness of the lysozyme particle surfaces, and the intra-cluster dynamics, features not included in our simple globular particle model. The theoretical results for the solution viscosity, eta, are in qualitative agreement with our experimental data even at higher concentrations. We demonstrate that semi-quantitative predictions of diffusion properties and viscosity of solutions of globular proteins are possible given only the equilibrium structure factor of proteins. Furthermore, we explore the effects of changing the attraction strength on H(q) and eta. PMID- 29448795 TI - Accelerated sampling by infinite swapping of path integral molecular dynamics with surface hopping. AB - To accelerate the thermal equilibrium sampling of multi-level quantum systems, the infinite swapping limit of a recently proposed multi-level ring polymer representation is investigated. In the infinite swapping limit, the ring polymer evolves according to an averaged Hamiltonian with respect to all possible surface index configurations of the ring polymer and thus connects the surface hopping approach to the mean-field path-integral molecular dynamics. A multiscale integrator for the infinite swapping limit is also proposed to enable efficient sampling based on the limiting dynamics. Numerical results demonstrate the huge improvement of sampling efficiency of the infinite swapping compared with the direct simulation of path-integral molecular dynamics with surface hopping.

AB - We recorded time-resolved infrared absorption spectra of transient species produced on irradiation at 308 nm of a flowing mixture of CH2I2/O2/N2/SO2 at 298 K. Bands of CH2OO were observed initially upon irradiation; their decrease in intensity was accompanied by the appearance of an intense band at 1391.5 cm-1 that is associated with the degenerate SO-stretching mode of SO3, two major bands of HCHO at 1502 and 1745 cm-1, and five new bands near >1340, 1225, 1100, 940, and 880 cm-1. The band near 1340 cm-1 was interfered by absorption of SO2 and SO3, so its band maximum might be greater than 1340 cm-1. SO3 in its internally excited states was produced initially and became thermalized at a later period. The rotational contour of the band of thermalized SO3 agrees satisfactorily with the reported spectrum of SO3. These five new bands are tentatively assigned to an intermediate 1,3,2-dioxathietane-2,2-dioxide [cyc-(CH2)O(SO2)O] according to comparison with anharmonic vibrational wavenumbers and relative IR intensities predicted for this intermediate. Observation of a small amount of cyc (CH2)O(SO2)O is consistent with the expected reaction according to the potential energy scheme predicted previously. SO3+HCHO are the major products of the title reaction. The other predicted product channel HCOOH+SO2 was unobserved and its branching ratio was estimated to be <5%. PMID- 29448797 TI - Laser desorption vs. electrospray of polyyne-threaded rotaxanes: Preventing covalent cross-linking and promoting noncovalent aggregation. AB - Laser-induced cross-linking of polyynes is successfully hindered when the polyyne is encapsulated as part of a rotaxane and therefore protected by a surrounding macrocycle. When the rotaxane is electrosprayed, however, noncovalent aggregate ions are efficiently formed. Aggregates of considerable size (including more than 50 rotaxane molecules with masses beyond 100k Da) and charge states (up to 13 charges and beyond) have been observed. Either protons or sodium cations act as the charge carriers. These aggregates are not formed when the individual components of the rotaxane, i.e., the macrocycle or the polyyne, are separately electrosprayed. This underlines the structural importance of the rotaxane for the aggregate formation. Straightforward force field calculations indicate that the polyyne thread hinders the folding of the macrocycles, which facilitates the bonding interaction between the two components. PMID- 29448798 TI - Effect of alkaline metal cations on the ionic structure of cryolite melts: Ab initio NpT MD study. AB - Ab initio molecular dynamics simulations in an NpT ensemble have been performed to study the role of alkaline metal cations (Me = Li, Na, K, Rb) on the structure and vibrational properties of melts of Me-cryolites (Me3AlF6) at T = 1300 K. In all melts examined in this work, the species AlF52- has been found to be formed at the highest abundance [from 58% (Li) to 70% (Na)] among the Al-containing anionic clusters. The concentration of clusters AlF4- increases with the size of cations while that of anions AlF63- follows the opposite trend and it becomes negligible in the melts of the K- and Rb-cryolites. The computed percentage of the Al atoms participating in the formation of dimers Al2Fm6-m bridged via common F atoms is significant only in the case of Li- and Na-cryolites (16% and 10%, respectively) and the formation of even larger aggregates is found to be unlikely in all four melts. The percentage of the F atoms that are not bound to Al is ~20% in all four melts and the ions formed by Me+ and F- are found to be only short lived. Vibrational analysis has been performed using the velocity autocorrelation functions computed for the Cartesian and selected internal coordinates describing Raman-active symmetric stretching vibrations of different AlFn species. The results of vibrational analysis allowed us to identify trends in the variation of positions and shapes of peaks corresponding to the anionic fragments AlF4-, AlF52 , and AlF63- with the size of cations, and these trends are found to be consistent with those deduced from the available Raman spectroscopy experiments. Our findings represent a new insight into the properties of cryolite melts, which will be useful for the interpretation of experimental data.

The fundamentals and a set of eigenfunctions complete up to about 3120 and 2660 cm-1 for trans- and cis-HCOOH, respectively, have been calculated and assigned using the improved relaxation method of the Heidelberg multi-configuration time-dependent Hartree package and an exact expression for the kinetic energy in valence coordinates generated by the TANA program. The calculated trans fundamental transition frequencies agree with experiment to within 5 cm-1. A few reassignments are suggested. Our results discard any cis trans delocalization effects for vibrational eigenfunctions up to 3640 cm-1 relative to trans zero point energy.

AB - Two-dimensional (2D) ultrafast spectroscopy is a powerful tool for studying the electronic and vibrational structures of complex systems. Unfortunately, the physical interpretation of these experiments is obscured by conceptual problems in classical response theory, i.e., the divergence of classical nonlinear response functions. We demonstrate that these difficulties are avoided by modeling classical 2D experiments nonperturbatively, illustrating that nonlinear spectroscopy and nonlinear response are not synonymous. Numerical simulations allow a direct comparison between classical and quantum 2D spectra for simple, weakly anharmonic systems relevant to vibrational spectroscopy. We find that nonperturbative classical theory-although differing in quantitative details accurately captures the key qualitative features of the quantum 2D spectrum, including the separation of the signal into wavevector-selected pathways, formation of cross peaks between coupled vibrational modes, and coherent beating in the signal as a function of waiting time (so-called "quantum beats"). These results are discussed in terms of a simple analytical model which captures the key physical features of classical 2D spectroscopy and provides a link between classical and quantum descriptions. One interesting conclusion from this comparison is that the "coherence" observed in ultrafast spectroscopy may (at least in vibrational experiments) be understood as a purely classical phenomenon, without reference to quantum mechanics.

AB - We previously demonstrated that we can image electronic excitations of quantum dots by single-molecule absorption scanning tunneling microscopy (SMA-STM). With this technique, a modulated laser beam periodically saturates an electronic transition of a single nanoparticle, and the resulting tunneling current modulation DeltaI(x0, y0) maps out the SMA-STM image. In this paper, we first derive the basic theory to calculate DeltaI(x0, y0) in the one-electron approximation. For near-resonant tunneling through an empty orbital "i" of the nanostructure, the SMA-STM signal is approximately proportional to the electron density phiix0,y02 of the excited orbital in the tunneling region. Thus, the SMA STM signal is approximated by an orbital density map (ODM) of the resonantly excited orbital at energy Ei. The situation is more complex for correlated electron motion, but either way a slice through the excited electronic state structure in the tunneling region is imaged. We then show experimentally that we can nudge quantum dots on the surface and roll them, thus imaging excited state electronic structure of a single quantum dot at different orientations. We use density functional theory to model ODMs at various orientations, for qualitative comparison with the SMA-STM experiment. The model demonstrates that our experimentally observed signal monitors excited states, localized by defects near the surface of an individual quantum dot. The sub-nanometer super-resolution imaging technique demonstrated here could become useful for mapping out the three dimensional structure of excited states localized by defects within nanomaterials.

AB - A revised version of the well-established B97-D density functional approximation with general applicability for chemical properties of large systems is proposed. Like B97-D, it is based on Becke's power-series ansatz from 1997 and is explicitly parametrized by including the standard D3 semi-classical dispersion correction. The orbitals are expanded in a modified valence triple-zeta Gaussian basis set, which is available for all elements up to Rn. Remaining basis set errors are mostly absorbed in the modified B97 parametrization, while an established atom-pairwise short-range potential is applied to correct for the systematically too long bonds of main group elements which are typical for most semi-local density functionals. The new composite scheme (termed B97-3c) completes the hierarchy of "low-cost" electronic structure methods, which are all mainly free of basis set superposition error and account for most interactions in a physically sound and asymptotically correct manner. B97-3c yields excellent molecular and condensed phase geometries, similar to most hybrid functionals evaluated in a larger basis set expansion. Results on the comprehensive GMTKN55 energy database demonstrate its good performance for main group thermochemistry, kinetics, and non-covalent interactions, when compared to functionals of the same class. This also transfers to metal-organic reactions, which is a major area of applicability for semi-local functionals. B97-3c can be routinely applied to hundreds of atoms on a single processor and we suggest it as a robust computational tool, in particular, for more strongly correlated systems where our previously published "3c" schemes might be problematic.

AB - Background It is difficult to distinguish between invasive pituitary adenomas (IPAs) and skull base chordomas based on tumor location and clinical manifestations. Purpose To investigate the value of the apparent diffusion coefficient (ADC), T2-weighted (T2W) imaging, and dynamic contrast enhancement (DCE) in differentiating skull base chordomas and IPAs. Material and Methods Data for 21 patients with skull base chordomas and 27 patients with IPAs involving the paranasal sinus were retrospectively reviewed, and all diagnoses were pathologically confirmed. Each patient underwent conventional 3.0 T magnetic resonance imaging (MRI), including, ADC, T2W imaging, and DCE sequences. Regions of interest were drawn in the mass and in normal white matter on ADC maps and T2W imaging. The mean ADC, normal ADC, T2W imaging signal intensity (SI), and relative T2-weighted (rT2W) imaging values were measured. DCE parameters, including types of time signal-intensity curves (TIC), enhancement peak (EP), and maximum contrast enhancement ratio (MCER), were calculated. Differences between skull base chordomas and IPAs were evaluated using the independent samples t test. Receiver operating characteristic (ROC) curve analyses were also performed. Results When comparing IPAs and chordomas, there were significant differences in mean ADC, normal ADC, rT2W imaging values, TIC, EP, and MCER ( P < 0.01). The areas under curves in the ROC analyses for normal ADC, mean ADC, T2W imaging, rT2W imaging, TIC, EP, and MCER were 1.0, 0.996, 1.0, 0.81, 0.987, and 0.987, respectively. Conclusion ADC, T2W imaging SI, and DCE-related parameters can contribute to the differential diagnosis of skull base chordomas and IPAs.

PMID- 29448806 TI - Endovascular treatment for the control of active vaginal bleeding from uterine cervical cancer treated with radiotherapy. AB - Background Endovascular treatment has become a significant therapeutic option for the management of intractable bleeding in gynecologic malignancies. However, the endovascular treatment types were almost never mentioned when active bleeding from different arteries was identified. Purpose To present angiographic details and evaluate clinical efficacy of endovascular treatments to control active vaginal bleeding in uterine cervical cancer patients treated with radiotherapy. Material and Methods In this retrospective study, six, consecutive cervical cancer patients treated with radiotherapy who underwent endovascular treatment for active vaginal bleeding were included. Angiographic findings, endovascular treatment details, and clinical outcomes were obtained. Results Ten endovascular procedures were technically successful, in which bleeding arteries were the internal iliac artery/its branches (n = 5), external iliac artery (EIA) (n = 3), uterine artery (n = 1), and superior rectal artery (n = 1), and bleeding manifested as contrast extravasation (n = 6), pseudoaneurysm (n = 1), or both (n = 3). Three of the four repeated procedures showed different bleeding sites from the primary ones. Stent graft was inserted to preserve the patency of the bleeding EIA in two patients. For another EIA rupture, both proximal and distal embolization were performed, followed by femoral-to-femoral bypass to preserve blood flow. Bleeding control within one month was achieved in 80% (8/10). One minor complication, mild transient pelvic pain, occurred in one patient. Conclusions Various endovascular treatment was feasible and effective to control active vaginal bleeding from cervical cancer. Repeated procedures showed commonly different bleeding foci and stent graft insertion was effective for preserving the patency of the large bleeding artery.

AB - OBJECTIVE: This study assessed the rates of hypertension awareness, treatment and control as well as the socio-economic and demographic correlates in Ghana. METHODS: This was a cross-sectional study. We used wave 1 of the World Health Organization (WHO) Study on global AGEing and adult health (SAGE) conducted between 2007and 2008. The sample was 5526 respondents aged 18 years and above. Descriptive statistics were used to describe the characteristics of the respondents and binary logistic regression was used to determine the correlates of hypertension awareness, treatment and control. RESULTS: The hypertension prevalence was 58.9%. About 19.0% of the individuals living with hypertension were aware of their hypertension; 67.6% of those who were aware of their hypertension were treating the condition, and; 11.6% of those who were on treatment had their hypertension controlled. Age, place of residence, level of education, employment status, ethnicity, and religion were associated with hypertension awareness and treatment. None of the factors was associated with hypertension control. CONCLUSION: Our study suggests high hypertension prevalence in Ghana, with low rates of awareness, treatment and control. Socio-economic and demographic factors are essential correlates of hypertension awareness and treatment in Ghana. The findings indicate the need to develop pragmatic intervention approaches such as rigorous education programs and use of the task shifting system, in addressing hypertension and issues related to it. PMID- 29448809 TI - Utilizing Machine Learning and Automated Performance Metrics to Evaluate Robot Assisted Radical Prostatectomy Performance and Predict Outcomes. AB - PURPOSE: Surgical performance is critical for clinical outcomes. We present a novel machine learning (ML) method of processing automated performance metrics (APMs) to evaluate surgical performance and predict clinical outcomes after robot assisted radical prostatectomy (RARP). MATERIALS AND METHODS: We trained three ML algorithms utilizing APMs directly from robot system data (training material) and hospital length of stay (LOS; training label) (<=2 days and >2 days) from 78 RARP cases, and selected the algorithm with the best performance. The selected algorithm categorized the cases as "Predicted as expected LOS (pExp-LOS)" and "Predicted as extended LOS (pExt-LOS)." We compared postoperative outcomes of the two groups (Kruskal-Wallis/Fisher's exact tests). The algorithm then predicted individual clinical outcomes, which we compared with actual outcomes (Spearman's correlation/Fisher's exact tests). Finally, we identified five most relevant APMs adopted by the algorithm during predicting. RESULTS: The "Random Forest-50" (RF 50) algorithm had the best performance, reaching 87.2% accuracy in predicting LOS (73 cases as "pExp-LOS" and 5 cases as "pExt-LOS"). The "pExp-LOS" cases outperformed the "pExt-LOS" cases in surgery time (3.7 hours vs 4.6 hours, p = 0.007), LOS (2 days vs 4 days, p = 0.02), and Foley duration (9 days vs 14 days, p = 0.02). Patient outcomes predicted by the algorithm had significant association with the "ground truth" in surgery time (p < 0.001, r = 0.73), LOS (p = 0.05, r = 0.52), and Foley duration (p < 0.001, r = 0.45). The five most relevant APMs, adopted by the RF-50 algorithm in predicting, were largely related to camera manipulation. CONCLUSION: To our knowledge, ours is the first study to show that APMs and ML algorithms may help assess surgical RARP performance and predict clinical outcomes. With further accrual of clinical data (oncologic and functional data), this process will become increasingly relevant and valuable in surgical assessment and training.

AB - Drug-eluting stents revolutionized the treatment of coronary artery disease with vastly improved outcomes compared with bare metal stents. As stent technology has evolved, a wide variety of antiproliferative drugs have been developed to prevent stent restenosis and stent thrombosis. The Resolute stent system (Medtronic, CA, USA) elutes zotarolimus from a multipolymer blend to prevent early and late stent related complications. The Resolute stents have evolved from the initial Resolute stent, to the Resolute IntegrityTM and most recently, the Resolute OnyxTM. These stents have been studied across a wide range of patients and coronary syndromes. They compare similarly in performance to their contemporary second generation stents. We present a review of the major trials involving these zotarolimus eluting stents. PMID- 29448811 TI - Production of a new mucilage compound in Lepidium sativum callus by optimizing in vitro growth conditions. AB - The mucilage in Lepidium sativum L. is considered a biologically active compound with diverse medicinal properties. Different explants (hypocotyls and leaf) were transferred to Murashige and Skoog (MS) medium supplemented with twelve different plant growth regulator combinations under two different incubations (light and dark). The best mucilage production from callus (36.76% g g-1 dry weight) was obtained in the MS medium supplemented with 1 mg L-1 of 2, 4-D and 2 mg L-1 of BAP under the light condition. The mucilage produced by callus culture was nearly three times more than the mucilage yield of the seeds. The glucose, arabinose + mannose and galactose were 43.4 (mg g-1 DW), 195.3 (mg g-1 DW) and 86.2 (mg g-1 DW) in the mucilage originated from seed, callus leaf and callus hypocotyl, respectively. The present study proposes an efficient method for producing large scales of mucilage with a favorable sugar aimed at food or pharmaceutical industries. PMID- 29448812 TI - A Qualitative Examination of Parent Engagement in a Family-Based Childhood Obesity Program. AB - Low parent engagement is frequently identified as a barrier to effective implementation of family-based childhood obesity prevention and control programs. A more nuanced understanding of factors affecting parent engagement is important for improving implementation and, ultimately, program efficacy. This qualitative study examined factors influencing parent engagement in a family-based childhood obesity prevention and control program. Semistructured interviews informed by the health belief model and the transtheoretical model were conducted with 22 predominantly Latina mothers following the scheduled conclusion of program activities. Spanish- and English-language interviews were transcribed, translated into English (if Spanish), coded, and summarized using established protocols. Differences between parents who attended at least two thirds of program activities and those who did not were examined. There were no significant demographic differences between parents who did and did not complete two thirds of program activities. Findings indicated that differences in parent engagement may be at least partially explained by differences in parental motivations for participating and in barriers and facilitators, such as children's level of support and enthusiasm for the program. Parents were highly satisfied with the program content and the community health workers who delivered the program. This study adds to emergent literature regarding parents' experiences in family-based childhood obesity prevention and control programs. Potential targets for improving program engagement are discussed. PMID- 29448813 TI - Biofouling in membrane bioreactors: nexus between polyacrylonitrile surface charge and community composition. AB - The influence of membrane surface charge on biofouling community composition during activated sludge filtration in a membrane bioreactor was investigated in this study using polyacrylonitrile-based membranes. Membranes with different surface properties were synthesized by phase inversion followed by a layer-by layer modification. Various characterization results showed that the membranes differed only in their surface chemical composition and charge, ie two of them were negative, one neutral and one positive. Membrane fouling experiments were performed for 40 days and the biofouling communities were analyzed. PCR-DGGE fingerprinting indicated selective enrichment of bacterial populations from the sludge suspension within the biofilms at any time point. The biofilm community composition seemed to change with time. However, no difference was observed between the biofilm community of differently charged membranes at specific time points. It could be concluded that membrane charges do not play a decisive role in the long-term selection of the key bacterial foulants. PMID- 29448814 TI - Measuring Prosociality: The Development of a Prosocial Behavioral Intentions Scale. AB - Prosociality is a critical issue in behavioral research. In this investigation, we developed a measure of prosocial behavioral intentions. Qualitative responses from two surveys (n = 465) and items from existing measures were used to generate a list of prosocial behaviors in which people might intend to engage. We factor analyzed responses to these items (n = 319) and retained the most common and representative items. The new measure demonstrated adequate internal consistency (n = 247, 147; alpha = .81, .83); convergent validity with past prosocial behavior (r = .51, .43), moral identity (r = .50, .55), and materialism (r = .30, -.20). The instrument also predicted prosocial behavior while controlling for a prior measure of prosocial intentions, Exp(B) = 1.99, Wald = 10.59, p = .001, thereby demonstrating incremental predictive validity. This 4-item scale could be used across contexts to advance the study of prosociality. PMID- 29448815 TI - Topiramate-Induced Acne in a 31-Year-Old Woman: A Case Report.

AB - Objective To evaluate and characterize the appearance of articular cartilage in the tibiofemoral joint of young professional soccer players using T2-relaxation time evaluation on magnetic resonance imaging (MRI). Design In this study, we included 57 male adolescents from the youth academy of a professional soccer team. The MRI scans were acquired of the knee joint of the supporting leg. An "early unloading" (minute 0) and "late unloading" (minute 28) T2-sequence was included in the set of images. Quantitative T2-analysis was performed in the femorotibial joint cartilage in 4 slices with each 10 regions of interest (ROIs). Statistical evaluation, using Wilcoxon signed-rank tests, was primarily performed to compare the T2 values of the "early unloading" and "late unloading." Results When comparing "early unloading" with "late unloading," our findings showed a significant increase of T2-relaxation times in the weightbearing femoral cartilage of the medial ( P < 0.001) and lateral ( P < 0.001) compartment of the knee and in the tibial cartilage of the medial compartment ( P < 0.001). Conclusion In this study, alterations of the cartilage were found with a maximum in the medial condyle where the biomechanical load of the knee joint is highest, as well as where most of the chronic cartilage lesions occur. To avoid chronic damage, special focus should be laid on this region. PMID- 29448817 TI - Treating Severe Knee Osteoarthritis with Combination of Intra-Osseous and Intra Articular Infiltrations of Platelet-Rich Plasma: An Observational Study. AB - Objective Assessing the therapeutic effects of a combination of intra-articular and intra-osseous infiltrations of platelet-rich plasma (PRP) to treat severe knee osteoarthritis (KOA) using intra-articular injections of PRP as the control group. Design In this observational study, 60 patients suffering from severe KOA were treated with intra-articular infiltrations of PRP (IA group) or with a combination of intra-osseous and intra-articular infiltrations of PRP (IO group). Both groups were matched for sex, age, body mass index, and radiographic severity (III and IV degree according to Ahlback scale). Clinical outcome was evaluated at 2, 6, and 12 months, using the Knee injury and Osteoarthritis Outcome Score (KOOS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaires. Results At 2, 6 and 12 months after treatment, IO group had a significant improvement in all KOOS and WOMAC subscales ( P < 0.05). On the contrary, patients of the IA group did not improve in any of the scores. Sixteen out of 30 IO group patients showed minimal clinically important improvement (MCII) whereas 8 out of 30 IA group patients showed this response at 6 months (26.7%; 95% CI -0.4 to 49.9; P = 0.037). At 12 months, 14 patients of IO group and 5 patients of the IA group showed MCII (30%; 95% CI 4.3 to 51.9; P = 0.013). No differences between groups were observed at 2 months. Conclusions PRP intra articular injections in severe KOA were not effective and did not provide any benefit. Combination of intra-articular and intra-osseous infiltrations of PRP was not clinically superior at 2 months, but it showed superior clinical outcomes at 6 and 12 months when compared with intra-articular injections of PRP. PMID- 29448818 TI - Managing in-hospital quality improvement: An importance-performance analysis to set priorities for ST-elevation myocardial infarction care. AB - BACKGROUND: A focus on specific priorities increases the success rate of quality improvement efforts for broad and complex-care processes. Importance-performance analysis presents a possible approach to set priorities around which to design and implement effective quality improvement initiatives. Persistent variation in hospital performance makes ST-elevation myocardial infarction care relevant to consider for importance-performance analysis. AIMS: The purpose of this study was to identify quality improvement priorities in ST-elevation myocardial infarction care. METHODS: Importance and performance levels of ST-elevation myocardial infarction key interventions were combined in an importance-performance analysis. Content validity indexes on 23 ST-elevation myocardial infarction key interventions of a multidisciplinary RAND Delphi Survey defined importance levels. Structured review of 300 patient records in 15 acute hospitals determined performance levels. The significance of between-hospital variation was determined by a Kruskal-Wallis test. A performance heat-map allowed for hospital-specific priority setting. RESULTS: Seven key interventions were each rated as an overall improvement priority. Priority key interventions related to risk assessment, timely reperfusion by percutaneous coronary intervention and secondary prevention. Between-hospital performance varied significantly for the majority of key interventions. The type and number of priorities varied strongly across hospitals. CONCLUSIONS: Guideline adherence in ST-elevation myocardial infarction care is low and improvement priorities vary between hospitals. Importance performance analysis helps clinicians and management in demarcation of the nature, number and order of improvement priorities. By offering a tailored improvement focus, this methodology makes improvement efforts more specific and achievable. PMID- 29448819 TI - Identifying the inhibition of TIR proteins involved in TLR signalling as an anti inflammatory strategy. AB - Toll/IL1 receptor (TIR) adaptor proteins continue to be an integral part of Toll like receptors' (TLR) signalling involved in inflammation. Signalling is likely to be initiated by these TIR adaptors when they are recruited to a TIR-TIR interface formed by TLR dimerization. Among these, myeloid differentiation factor 88 (MyD88), MyD88 adapter-like protein (Mal), TIR domain-containing adaptor protein inducing interferon-beta (TRIF) and TRIF-related adaptor molecule (TRAM) play pivotal roles at many steps in the signalling events leading to inflammation. The presence of the conserved BB loop residues in the TIR domain of all these important adaptor proteins make them possible targets for inhibition by synthetic compounds. We have designed compounds based on an already known MyD88 TIR dimerization inhibitor, T6167923, which binds well not only to the original target but also to the TIR domains of Mal, TRIF and TRAM. The designed inhibitors are based on modifications of the bromophenyl-sulphonyl-thiophenyl-piperazine carboxamide series of compounds. We have further suggested modifications in these high-affinity compounds for efficient absorption inside the body. Further, a pharmacophore model highlighting important structural interaction features has been developed. The screened compounds are better in binding to the TIR proteins then the parent compound and hence are good starting points for multi-TIR inhibition. PMID- 29448820 TI - Evaluating the reporting of adverse events in controlled clinical trials conducted in 2010-2015 on migraine drug treatments. AB - Background In 2008, the International Headache Society published guidelines on the "evaluation and registration of adverse events in clinical drug trials on migraine". They listed seven recommendations for reporting adverse events in randomized controlled trials on migraine. The present study aimed to evaluate adherence to these recommendations, and based on the results, to recommend improvements. Methods We searched the PubMed/MEDLINE database to identify controlled trials on migraine drugs published from 2010 to 2015. For each trial, we noted whether five of the recommended parameters were presented. In addition, we noted whether adverse events were reported in abstracts. Results We identified 73 trials; 51 studied acutely administered drugs and 22 studied prophylactic drugs for migraine. The number of patients with any adverse events were reported in 74% of acute-administration and 86% of prophylactic drug trials. Only 30 (41%) of the 73 studies reported adverse events with data in the abstracts, and 27 (37%) abstracts did not mention adverse events. Conclusion Adverse events, both frequency and symptoms, should be reported to allow a fair judgement of benefit/tolerability ratio when randomized controlled trials in migraine treatment are published. Clinically significant adverse events should be included in the abstract of every randomized controlled trial in migraine treatment. PMID- 29448822 TI - Ice-liquid isotope fractionation factors for 18O and 2H deduced from the isotopic correction constants for the triple point of water. AB - The stable isotopes of water are extensively used as tracers in many fields of research. For this use, it is essential to know the isotope fractionation factors connected to various processes, the most important of which being phase changes. Many experimental studies have been performed on phase change fractionation over the last decades. Whereas liquid-vapour fractionation measurements are relatively straightforward, vapour-solid and liquid-solid fractionation measurements are more complicated, as maintaining equilibrium conditions when a solid is involved is difficult. In this work, we determine the ice-liquid isotope fractionation factors in an indirect way, by applying the Van't Hoff equation. This equation describes the relationship of the fractionation factors with isotope-dependent temperature changes. We apply it to the recently experimentally determined isotope dependences of the triple point temperature of water [Faghihi V, Peruzzi A, Aerts-Bijma AT, et al. Accurate experimental determination of the isotope effects on the triple point temperature of water. I. Dependence on the 2H abundance. Metrologia. 2015;52:819-826; Faghihi V, Kozicki M, Aerts-Bijma AT, et al. Accurate experimental determination of the isotope effects on the triple point temperature of water. II. Combined dependence on the 18O and 17O abundances. Metrologia. 2015;52:827-834]. This results in new values for the 2H (deuterium) and 18O fractionation factors for the liquid-solid phase change of water, which agree well with existing, direct experimental data [Lehmann M, Siegenthaler U. Equilibrium oxygen- and hydrogen-isotope fractionation between ice and water. J Glaciol. 1991;37:23-26]. For 2H, the uncertainty is improved by a factor of 3, whereas for 18O the uncertainty is similar. Our final results are alphaS-L (2H/1H) = 1.02093(13), and alphaS-L (18O/16O) = 1.002909(25), where the latter is the weighted average of the previous experimental study and this work. PMID- 29448823 TI - Chemical constituents of Genista numidica Spach aerial parts and their antimicrobial, antioxidant and antityrosinase activities. AB - A previously undescribed triterpenoid saponin, 3-O-[alpha-l-rhamnopyranosyl-(1 >2)-{beta-d-glucopyranosyl-(1->6)-}beta-d-galactopyranosyl-(1->2)-beta-d glucuronopyranosyl]-sophoradiol (1), in addition to twenty-nine known constituents (2-30) were isolated from the aerial parts of Genista numidica Spach. Structures elucidation was performed by comprehensive 1D- and 2D-NMR analyses and HRESIMS. The extracts, fractions and isolated compounds were evaluated for their antibacterial, antioxidant and tyrosinase inhibitory activities. The experimental findings indicated that genistin (16), isosalipurpol (27), and koaburaside (29) have moderate to low antibacterial activity against E. faecalis, S. aureus, S. epidermidis and P. aeruginosa bacteria with MICs ranging from 31.2 to 125 MUg/mL. Compounds 19 and 27 exhibited a good antiradical activity potential (IC50 11.8 and 11.1 MUg/mL, respectively). Only compounds 23, 27 and 28 exhibited low inhibitory effect against mushroom tyrosinase (IC50 from 90.2 to 225.6 MUg/mL). PMID- 29448824 TI - Influence of Diagnosis and Other Factors on Patients' Expectations of Foot and Ankle Surgery. AB - BACKGROUND: Many patient factors have been associated with higher or lower expectations of orthopedic surgery. In foot and ankle surgery, the diverse diagnoses seen may also influence expectations. The aim of this study was to investigate the relationship between diagnosis and patients' preoperative expectations of elective foot and ankle surgery. METHODS: Two hundred seventy eight patients undergoing elective foot or ankle surgery for 1 of 7 common diagnoses were enrolled in a prospective cohort study. Preoperative expectations were assessed with the Hospital for Special Surgery Foot & Ankle Surgery Expectations Survey. Patients also completed the Foot & Ankle Outcome Score, Short Form 12, pain visual analog scale, and questionnaires for depressive and anxiety symptoms. Demographic and clinical data were collected. Patient factors and diagnosis were analyzed using multivariate regression analysis to identify independent predictors of higher expectations and determine the effect of diagnosis relative to other patient factors on expectations. RESULTS: The multivariate regression analysis adjusting for demographics and other clinical characteristics showed that diagnosis contributed the most to the model, accounting for 10.5% of the variation in expectations survey scores. Patients with mid- or hindfoot arthritis ( P < .001), hallux valgus ( P = .001), or hallux rigidus ( P = .005) had lower scores (lower expectations) than those with ankle instability or osteochondral lesion. In the model, female sex ( P = .001), non Caucasian race ( P = .031), and lower scores on the Foot & Ankle Outcome Score daily activities subscale ( P = .024) were associated with higher scores. CONCLUSIONS: Diagnosis of ankle instability or osteochondral lesion, female sex, non-Caucasian race, and lower Foot & Ankle Outcome Score daily activities subscale score were all associated with higher expectations. These findings may help inform and guide surgeons as they counsel patients preoperatively. LEVEL OF EVIDENCE: Level II, cross-sectional study. PMID- 29448825 TI - Radiographic Prognostic Factors for Selective Soft Tissue Release After Ponseti Failure in Young Pediatric Clubfoot Patients. AB - BACKGROUND: Selective soft tissue release (SSTR), which includes a combination of abductor hallucis, tibialis posterior, and Achilles lengthening, has been used in patients with recurrent clubfoot deformity after Ponseti treatment. The aim of this study was to investigate the prognostic factors for recurrence of clubfoot deformity after SSTR. METHODS: Consecutive patients with idiopathic clubfoot and residual or recurrent deformity after Ponseti treatment underwent SSTR between 2005 and 2013. The clinical and radiologic characteristics before and after SSTR were analyzed. The ability of radiologic factors to predict recurrence of clubfoot deformity was assessed using multivariate analysis. Rigid deformities of forefoot adduction, and hindfoot varus, and equinus were examined separately. Forty-three patients with 64 clubfeet were included. RESULTS: Postoperative improvement in the talo-first metatarsal angle on the anteroposterior view, the talocalcaneal angle on the lateral view, and the tibiocalcaneal angle on the lateral view independently predicted recurrence after SSTR. Additionally, the preoperative talocalcaneal angles on the anteroposterior and lateral views were also significant predictors, but these angles did not significantly improve after SSTR. CONCLUSIONS: SSTR seems to be an effective surgical modality only in milder deformities. Among patients with poor talocalcaneal angles, a high percentage required further surgery. The present results may be useful for the choice of SSTR or more extensive surgery. LEVEL OF EVIDENCE: Level III, retrospective case control study. PMID- 29448826 TI - Complications of Supine Surgical Achilles Tendon Repair. AB - BACKGROUND: Open Achilles tendon surgery with the patient in the supine position potentially avoids the complications of the prone position, but the safety and viability of the supine position for this procedure are not known. The aim of this study was to test the hypothesis that supine positioning for open repair of acute Achilles tendon ruptures would be safe, with low wound and neurologic complication rates. METHODS: Supine position safety in acute Achilles tendon repair was investigated. Consecutive cases of supine Achilles tendon surgical repair performed by one surgeon from 2010 to 2015 were retrospectively reviewed. Patients were included if they were surgically treated with primary repair in the supine position within 15 days of injury and did not undergo concomitant surgery. A paramedian incision 1 cm medial to the Achilles sheath was used. Initial chart review identified 161 patients who underwent any type of Achilles tendon surgery in the supine position, of whom 45 patients met the inclusion criteria. This group included 39 men and 6 women with an average age of 41 years (range, 20-66 years). Median length of follow-up was 116 days (range, 25-1,589 days). Average body mass index was 29 kg/m2 (range, 23-36 kg/m2). RESULTS: There were no infections, sural nerve injuries, or reruptures. CONCLUSIONS: The supine position was safe for primary open Achilles tendon repair, with no wound or neurologic complications. LEVEL OF EVIDENCE: Level IV, case series. PMID- 29448827 TI - Outcomes After Primary Repair of Insertional Ruptures of the Achilles Tendon. AB - BACKGROUND: Achilles tendon insertional sleeve avulsions occur when the Achilles distal tendon sleeve ruptures off of its insertion into the calcaneal tuberosity, sometimes with a small bony fragment from calcific tendinosis. Little evidence exists describing the outcomes and rerupture rate after operative management of Achilles tendon sleeve avulsions. METHODS: A retrospective chart review was performed to identify patients who sustained an Achilles sleeve avulsion injury treated with operative repair between October 2005 and July 2014. A cohort of 16 patients from the general population and 12 professional athletes were included in the study. The primary outcome variable was rerupture of the Achilles tendon or need for revision surgery. Secondary outcome variables included the Coughlin Satisfaction Scale, visual VR-12, and Foot and Ankle Ability Measure (FAAM). RESULTS: In the general population cohort, median follow-up was 8.1 years (range, 3.2-11.1 years). The median FAAM Activities of Daily Living score was 100 (range, 42.9-106), and the median FAAM Sports score was 100 (range, 7.1-103.6). The median VR-12 Mental Component Score was 66.9 (range, 45.6-71.8), and the median VR-12 Physical Component Score was 53 (range, 30.8-57.5). In the cohort of professional athletes, preceding insertional Achilles symptoms were present in 91.7% (11/12) of athletes for more than 9 months prior to rupture. All athletes returned to play with an average time of 13.4 months. No patients sustained a rerupture in the follow-up period. CONCLUSION: Operative repair of Achilles tendon sleeve avulsions was safe and effective with high patient satisfaction and good clinical outcomes in patients from the general population. LEVEL OF EVIDENCE: Level IV, retrospective case series. PMID- 29448828 TI - Role of terminal warm blood cardioplegia in complex congenital heart surgery. AB - Introduction Myocardial protection is vital to ensure successful open heart surgery. Cardioplegic solution is one method to achieve good myocardial protection. Inevitably, ischemia-reperfusion injury occurs with aortic crossclamping. Histidine-tryptophan-ketoglutarate solution is a frequently used cardioplegia for complex congenital heart surgery. We postulated that addition of terminal warm blood cardioplegia before removal of the aortic crossclamp might improve myocardial protection. Method A randomized controlled trial was conducted on 109 cyanotic patients aged, 1 to 5 years who underwent complex biventricular repair. They were divided into a control group of 55 patients who had histidine tryptophan-ketoglutarate only and a treatment group of 54 who had histidine tryptophan-ketoglutarate with terminal warm blood cardioplegia. Endpoints were clinical parameters, troponin I levels, and caspase-3 as an apoptosis marker. Results The incidence of low cardiac output syndrome was 34%, with no significant difference between groups (35.2% vs. 33.3%, p = 0.84). The incidence of arrhythmias in our treatment group was lower compared to the control group (36% vs. 12%, p = 0.005). Troponin I and caspase-3 results did not show any significant differences between groups. For cases with Aristotle score >= 10, weak expression of caspase-3 in the treatment group post-cardiopulmonary bypass was lower compared to the control group. Conclusion For complex congenital cardiac surgery, the addition of terminal warm blood cardioplegia does not significantly improve postoperative clinical or metabolic markers.

AB - Mucormycosis is an opportunistic fungal infection that can infect different regions of the body. This entity may present in rhinocerebral, pulmonary, cutaneous, and disseminated forms. Although pulmonary mucormycosis is usually seen as an invasive parenchymal consolidation or cavitation, it may rarely present as an endobronchial mass. We describe a case of endobronchial mucormycosis in which the fungal mass was completely removed via rigid bronchoscopy before medical therapy. PMID- 29448831 TI - Pleural drainage using drainage bag for thoracoscopic lobectomy. AB - Objective This study was designed to compare the effectiveness and convenience of a drainage bag and a chest bottle following thoracoscopic lobectomy. Methods We conducted a test to ensure that the drainage bag was characterized by easy drainage and an antireflux effect. Thereafter, the drainage bag was used in all thoracic operations in our service. To understand the usefulness of the drainage bag, a retrospective cohort study enrolled 30 patients who had a drainage bag after thoracoscopic lobectomy and compared them with 30 similar patients operated on previously who had chest bottles. Variables studied included total drainage volume, duration of drainage, complications, and satisfaction of the care providers. Results There was no significant difference between the chest bottle and drainage bag groups respectively in terms of total drainage (697.5 +/- 89.7 vs. 614.1 +/- 76.6 mL, p = 0.483) or duration of drainage (4.23 +/- 0.38 vs. 4.43 +/- 0.38 days, p = 0.713). No device-related complication was observed. After our experience with the drainage bag, we abandoned use of the chest bottle. The drainage bag was more convenient for patients and promoted early ambulation as well improving cost effectiveness. Most care providers preferred to use the drainage bag (p = 0.000). Conclusion The drainage bag is superior to the chest bottle for postoperative drainage. PMID- 29448832 TI - Bland or tumor pulmonary artery stump thrombosis? PMID- 29448833 TI - Efficacy and safety of luseogliflozin added to insulin therapy in Japanese patients with type 2 diabetes: a multicenter, 52-week, clinical study with a 16 week, double-blind period and a 36-week, open-label period. AB - OBJECTIVE: To evaluate the efficacy and safety of luseogliflozin in Japanese patients with type 2 diabetes (T2D) inadequately controlled with insulin monotherapy. METHODS: This 52-week multicenter study entailed a 16-week, double blind period followed by a 36-week, open-label period. Patients were randomized to receive either luseogliflozin 2.5 mg (n = 159) or placebo (n = 74) during the double-blind period. All patients who entered the open-label period received luseogliflozin. Major efficacy endpoints included the changes from baseline in HbA1c, fasting plasma glucose (FPG), postprandial plasma glucose (PPG) and bodyweight. Safety assessments included adverse events, laboratory tests and vital signs. RESULTS: In the double-blind period, luseogliflozin significantly decreased HbA1c (-1.18%), FPG (-42.4 mg/dL), 2 hour PPG (-68.7 mg/dL) and bodyweight (-1.27 kg) compared with placebo (all p < .001); these reductions were maintained over 52 weeks. The changes from baseline at Week 52 were -1.00%, -35.1 mg/dL, -68.8 mg/dL and -1.81 kg, respectively (all p < .001). In the placebo group, favorable glycemic control and bodyweight reduction were also observed after switching to luseogliflozin. Most adverse events were mild in severity. During the double-blind period, the incidences of hypoglycemia were 20.8% and 13.5% in the luseogliflozin and placebo groups, respectively. During the 52 weeks of luseogliflozin treatment, the frequency of hypoglycemia was 33.3%, but no serious hypoglycemia occurred. The safety profile other than hypoglycemia was also acceptable. There were no new safety concerns about luseogliflozin added to insulin. CONCLUSION: Luseogliflozin added to insulin therapy significantly improved glycemic control with bodyweight reduction and was well tolerated in Japanese patients with T2D.

AB - AIM: Our review evaluated both the effects of single-occupancy patient rooms (SPRs) on patient outcomes for hospitalized adults and user opinion related to SPRs. BACKGROUND: In 2006, a requirement for SPRs in hospitals was instituted in the United States. This systematic literature review evaluates research published since that time to evaluate the impact of SPRs. METHODS: The review adheres to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Databases searched included MEDLINE, CINAHL, and Scopus. Supplemental searches were performed. We included studies reporting patient outcomes or user opinion related to SPRs. Appraisal was conducted using a dual appraisal system of evidence levels and methodological quality. RESULTS: Forty-three studies qualified for appraisal. Three were excluded due to methodological quality (no appraisal score). One study was appraised for three individual outcomes (i.e., falls, infections, and user opinion). Eleven studies with low methodological quality scores were not included in the narrative synthesis. Overall, 87% of studies reported advantages associated with SPRs (some a combination of advantages and disadvantages or a combination of advantages and neutral results). Outcomes with the best evidence of benefit include communication, infection control, noise reduction/perceived sleep quality, and preference/perception. CONCLUSION: SPRs seem to result in more advantages than disadvantages. However, healthcare is a complex adaptive system, and decisions for 100% SPRs should be reviewed alongside related issues, such as necessary workflow modifications, unit configuration and other room layout decisions, patient populations, staffing models, and inherent trade-offs (e.g., the advantages of privacy compared to disadvantage of isolation). PMID- 29448835 TI - Here's Some Great Research! Now What? Translating Research Into Practice. PMID- 29448836 TI - AAV8 Gene Therapy Rescues the Newborn Phenotype of a Mouse Model of Crigler Najjar. AB - Adeno-associated viral (AAV) vectors can target the liver, making them an attractive platform for gene therapy approaches that require the correction of hepatocytes. Crigler-Najjar syndrome is an autosomal recessive disorder of bilirubin metabolism that occurs when the liver's uridine diphosphate glucuronosyl transferase 1A1 (UGT1A1) enzyme activity is partially or completely absent. This syndrome is characterized by elevated bilirubin levels in the blood. An AAV8 vector was developed expressing a codon-optimized human version of UGT1A1 from a liver-specific promoter. High doses of the vector rescued neonatal lethality in newborn UGT1 knockout (KO) mice, which serve as a model of Crigler Najjar syndrome, and significantly increased survival from 5 to 270 days. Newborn UGT1 KO mice treated with AAV had serum total bilirubin levels that were 5.7 times higher than the levels seen in heterozygous and wild-type mice, likely due to dilution of vector genome copies (GC) in the liver resulting from a proliferation of hepatocytes during growth of the animal. The elevation in serum total bilirubin levels in adult UGT1 KO mice depended on the AAV8 vector dose. At doses <1011 GC/mouse, total bilirubin levels returned to those seen in phototherapy-rescued UGT1 KO mice. Mice injected with vector at 1011 or 3 * 1011 GC/mouse had sustained reduced total bilirubin levels throughout the duration of the study. When an AAV8 vector was re-administered in mice with elevated total bilirubin levels, serum total bilirubin levels decreased to wild-type levels (0.1 0.3 mg/dL) in mice that received a vector dose of 3 * 1012 GC/kg. Therefore, a low-level and likely transient decrease in serum total bilirubin during the first days of life is necessary for rescuing the lethal phenotype present in the neonatal UGT1 KO mouse. Furthermore, it was possible to ablate the elevated total bilirubin levels in adult mice by re-administering an AAV8 vector. PMID- 29448837 TI - Restoring tracheal defects in a rabbit model with tissue engineered patches based on TGF-beta3-encapsulating electrospun poly(l-lactic acid-co-epsilon caprolactone)/collagen scaffolds. AB - Long segment tracheal stenosis often has a poor prognosis due to the limited availability of materials for tracheal reconstruction. Tissue engineered tracheal patches based on electrospun scaffolds and stem cells present ideal solutions to this medical challenge. However, the established engineering process is inefficient and time-consuming. In our research, to optimize the engineering process, core-shell nanofilms encapsulating TGF-beta3 were fabricated as scaffolds for tracheal patches. The morphological and mechanical characteristics, degradation and biocompatibility of poly(l-lactic acid-co-epsilon caprolactone)/collagen (PLCL/collagen) scaffolds with different compositions (PLCL:collagen 75:25, 50:50 and 25:75, respectively) were comparatively evaluated to determine the preferable compositional ratio. Then the chondrogenesis-inducing potential is investigated, and tracheal patches based on electrospun scaffolds and bone marrow mesenchymal stem cells (BMSCs) were constructed to restore tracheal defects in rabbit models. The results indicated that core-shell scaffolds with a PLCL/collagen proportion of 75:25 were eligible for tracheal patches. The stable and sustained release of TGF-beta3 from scaffolds could efficiently promote the chondrogenic differentiation of BMSCs and shorten the incubation time. Tracheal integrity was well maintained for 2 months after restoration; meanwhile, re-epithelialization also achieved. In conclusion, TGF beta3-encapsulating core-shell electrospun scaffolds with a PLCL/collagen proportion of 75:25 could be used to optimize engineering process of tracheal patches. PMID- 29448838 TI - Novel methotrexate soft nanocarrier/fractional erbium YAG laser combination for clinical treatment of plaque psoriasis. AB - Psoriasis is a commonly encountered chronic dermatological disease, presenting with inflammatory symptoms in patients. Systemic treatment of psoriasis is associated with several adverse effects, therefore the development of a customized topical treatment modality for psoriasis would be an interesting alternative to systemic delivery. The therapeutic modality explored in this article was the comparative treatment of psoriatic patients using nanoparticulated methotrexate in the form of jojoba oil-based microemulsion with or without fractional erbium YAG laser. Assessment parameters included follow-up photography for up to 8 weeks of treatment, estimation of the psoriasis severity [TES (thickness, erythema, scales)] score, and histopathological skin evaluation. The prepared methotrexate microemulsion was clinically beneficial and safe in treatment of psoriasis vulgaris. The concomitant use of the fractional laser provided improvement in the psoriatic plaques within shorter time duration (3 weeks compared to 8 weeks of treatment), presenting an alternative topical treatment modality for psoriasis vulgaris. PMID- 29448839 TI - Role of growth factors and biomaterials in wound healing. AB - Wound healing is a biological complex process that involves several cell types under the control and regulation of several growth factors and cytokines. There have been efforts to study the therapeutic effects of granulocyte-macrophage colony-stimulating factor, platelet-derived growth factor, transforming growth factor-beta, vascular endothelial growth factor and basic fibroblast growth factor on chronic wounds. In addition, the effects of biomaterials such as nano fibrous chitin and chitosan have been proven to be effective on wound healing. Furthermore, stem cell therapy using adipose-derived stem cells (ASCs) has been developed as a new therapeutic method for wound repair and healing. In this review, we will summarize the role of stem cells; growth factors and biomaterials in wound healing and repair. PMID- 29448840 TI - Inverse association between serum albumin and future risk of venous thromboembolism: interrelationship with high sensitivity C-reactive protein. AB - PURPOSE: We aimed to assess the prospective association of serum albumin with venous thromboembolism (VTE) risk and evaluate if the association is independent of or modified by inflammation, as measured by high sensitivity C-reactive protein (hsCRP). DESIGN: We analysed data of 2176 men aged 42-61 years free from VTE in the Kuopio Ischemic Heart Disease study, with serum albumin concentrations measured at baseline using Coulter's bromocresol purple colorimetric assays. Hazard ratios (HRs) (95% confidence intervals [CI]) were calculated for VTE. RESULTS: There were 109 validated cases of VTE recorded during a median follow-up of 24.9 years. The risk of VTE increased linearly below a serum albumin concentration of ~48 g/l. In Cox regression analysis adjusted for established risk factors and other potential confounders, the HR (95% CI) for VTE per 1 standard deviation lower serum albumin was 1.23 (1.02-1.47). The association remained persistent on further adjustment for hsCRP 1.22 (1.01-1.46). Furthermore, the association was not modified by hsCRP and persisted on exclusion of men with elevated hsCRP levels. CONCLUSIONS: In middle-aged Caucasian men, low serum albumin is associated with an increased risk of VTE, consistent with a linear dose-response relationship. The association is independent of and not modified by inflammation. Key messages * Serum albumin may be associated with future risk of venous thromboembolism (VTE); however, the shape, nature, magnitude and consistency of the association is uncertain. * In a population based prospective cohort study, low serum albumin was associated with an increased risk of VTE in a linear dose-response manner and this association was independent of and not modified by inflammation. * Serum albumin concentrations may play a role in the development of VTE. PMID- 29448841 TI - The Association of Serum Iron-Binding Proteins and the Antioxidant Parameter Levels in Age-Related Macular Degeneration. AB - PURPOSE: Age-related macular degeneration (AMD) is the leading cause of the irreversible central visual loss among the elderly in the developed countries. Iron is considered a potent generator of the oxidative damage whose levels increase with age, potentially exacerbating the age-related diseases. The aim of this study was to assess the serum values of iron, and iron-binding proteins (transferrin, ferritin, and haptoglobin) in patients with AMD along with the parameters of the antioxidant defense: superoxide dismutase (SOD), glutathione peroxidase (GPx), glutathione reductase, and total antioxidant status (TAS), in order to analyze the possible impact of iron and iron-binding proteins to the development of oxidative stress in AMD patients, and the association of the selected parameters with the AMD. In addition, the aim was to examine the gender differences and calculate the cutoff points of tested parameters that could be associated with AMD. MATERIAL AND METHODS: A cross-sectional study included 55 AMD patients aged 71.7 +/- 7.36 years and 65 aged-matched control subjects aged 70.25 +/- 6.46 years. RESULTS: Significantly lower ferritin (P = 0.025), SOD (P = 0.026), GPx (P = 0.019), and TAS (P < 0.004) values were found in patients with AMD compared to the controls (P < 0.05). Significant association of GPx < 27 U/gHb (odds ratio [OR]: 1.13; 95% confidence interval [CI] 0.78-2.10; P = 0.049), TAS < 1.25 mmol/L (OR: 5.77; 95% CI 0.98-367.0; P < 0.000), ferritin < 84.8 pg/mL (OR: 2.52; 95% CI 1.37-4.62; P = 0.002), and haptoglobin<1.51 g/L (OR: 1.94; 95% CI 1.05-3.56; P = 0.031) was found with the AMD. According to receiver operating characteristic curve analysis, ferritin concentration <84.8 pg/L, GPx < 27 U/gHb, and TAS < 1.25 mmol/L have sufficient predictive ability for AMD. CONCLUSION: Significantly reduced capacity of the antioxidant defense system and iron-binding storage proteins (ferritin) found in AMD could have an important role in the development of increase oxidative stress in AMD patients. PMID- 29448842 TI - Knockdown of NRAGE induces odontogenic differentiation by activating NF-kappaB signaling in mouse odontoblast-like cells. AB - PURPOSE: Neurotrophin receptor-interacting MAGE homologue (Nrage) plays an important role in bone development and the metabolism of normal skeletal structures. Our previous study showed that Nrage inhibited the odontogenic differentiation of mouse dental pulp cells. However, the potential roles and mechanism of Nrage in regulating odontogenic differentiation are unknown. The aim of this study was to investigate the molecular mechanism of Nrage in odontogenic differentiation of mouse odontoblast-like cells. MATERIALS AND METHODS: Endogenous expression of Nrage was stably downregulated by lentivirus-mediated shRNA. Mineralized nodules formation was detected by alizarin red S staining. Dmp 1, Dspp, and ALP mRNA and protein levels were detected by qRT-PCR and western blotting, respectively. In addition, ALPase activity was detected. Confocal microscopy and co-immunoprecipitation (co-IP) were used to analyze the interactions between NRAGE and NF-kappaB signaling molecules. An IKK inhibitor was also used in the study. RESULTS: NRAGE expression in odontoblasts was downregulated during mouse first maxillary molar development. Moreover, NRAGE expression was downregulated during odontogenic differentiation of odontoblast like cells. NRAGE knockdown significantly upregulated DMP1 and DSP expression, increased ALPase activity, and promoted mineralized nodule formation. In addition, NRAGE knockdown increased the translocation of NF-kappaB1 to the nucleus and phosphorylation levels of p65. Co-IP results showed that NRAGE bound to IKKbeta. Most importantly, the promoting effect of Nrage knockdown on odontoblastic differentiation was reduced after treatment with an IKK inhibitor. CONCLUSIONS: Our data confirmed that NRAGE is an important regulator of odontogenic differentiation of odontoblasts by inhibiting the NF-kappaB signaling pathway through binding to IKKbeta.

AB - INTRODUCTION: Nonalcoholic fatty liver disease (NAFLD) has an increasing prevalence worldwide. At present, no specific pharmacotherapy is approved for NAFLD. Simple steatosis and nonalcoholic steatohepatitis (NASH) can progress to liver fibrosis that is associated with mortality in NAFLD. The recruitment of inflammatory monocytes and macrophages via chemokine receptor CCR2 as well as of lymphocytes and hepatic stellate cells via CCR5 promote the progression of NASH to fibrosis. Areas covered: I summarize preclinical and clinical data on the efficacy and safety of the dual CCR2/CCR5 inhibitor cenicriviroc (CVC, also TBR 652 or TAK-652) for the treatment of NASH and fibrosis. In animal models of liver diseases, CVC potently inhibits macrophage accumulation in the liver and ameliorates fibrosis. In a phase 2b clinical trial (CENTAUR) on 289 patients with NASH and fibrosis, CVC consistently demonstrated liver fibrosis improvement after 1 year of therapy and had an excellent safety profile, leading to the implementation of a phase 3 trial (AURORA). Expert opinion: Preclinical and clinical data support the development of CVC as a safe and potent antifibrotic agent. However, open questions around CVC are the durability of antifibrotic responses, divergent effects on NASH versus fibrosis, potential long-term concerns and the expected path to approval. PMID- 29448845 TI - A systematic review of economic evaluations of tyrosine kinase inhibitors of vascular endothelial growth factor receptors, mammalian target of rapamycin inhibitors and programmed death-1 inhibitors in metastatic renal cell cancer. AB - INTRODUCTION: The therapeutic categories of tyrosine kinase inhibitors of vascular endothelial growth factor receptors, mammalian target of rapamycin inhibitors and programmed death-1 inhibitors have transformed the treatment of metastatic renal cell cancer. Nevertheless, this comes at an increased cost, in tandem with similar fiscal pressures in the broader oncology sector, which may jeopardize the sustainability of health systems. Areas covered: To this direction, the economic evaluation of these agents is essential for rational and efficient decision-making and resource allocation process. The aim of this study is to glean, assess and present an outline of the available cost-effectiveness studies of these agents in the management of metastatic renal cell cancer. Expert Commentary: We concluded that the results of the economic evaluations are pertinent, apart from the product under evaluation, to the country setting as well. PMID- 29448846 TI - Are infectious diseases and microbiology new fields for thermal therapy research? AB - Antimicrobial chemotherapy and surgery are classical methods for treating infectious diseases. However, there is a need for alternative methods to cure infections caused by antibiotic-resistant pathogens, recurrent or chronic infections, and unreachable local infections in which the use of drugs or surgery is anatomically and physically restricted. Several micro-organisms are known to be sensitive to mild hyperthermia, and this sensitivity is one of the potential benefits proposed for the host during an episode of fever. Additionally, some immunological or biophysical changes occur during hyperthermia. These changes may be useful for eliminating thermo-susceptible microbial pathogens using local heat therapy. There are several experimental studies proposing the use of hyperthermia to treat local infections. The infected organs or tissues may be heated up to a temperature that can inhibit invading microorganisms. Here, it is hypothesised that local heat therapy may become an alternative or adjuvant method for curing local infections. Here, we highlight the potential for local hyperthermia in the treatment of bacterial infections caused by thermo-susceptible pathogens in a systematic plan. If the proposed thermal-microbiology concepts and local thermal therapies can be adapted to clinical microbiology and infectiology, new medical fields, such as thermo-microbiology and thermo-infectiology, may be created in the future. PMID- 29448847 TI - Effect of early cumulus cells removal and early rescue ICSI on pregnancy outcomes in high-risk patients of fertilization failure. AB - OBJECTIVE: The objective of this retrospective study was to evaluate clinical outcomes of early cumulus cells removal and early rescue intracytoplasmic sperm injection (ICSI) in high-risk patients of fertilization failure during human in vitro fertilization (IVF). METHODS: A total of 5,518 patients were enrolled between January 2014 to December 2016. Of which 505 couples performed short insemination with >30% fertilization rate were included in short-term IVF group, 102 patients detected total fertilization failure (TFF) were treated with early rescue ICSI (R-ICSI group), and 4911 couples underwent conventional IVF with overnight co-incubation of gametes (traditional IVF group). The clinical outcomes were analyzed among the three groups. RESULTS: The embryo implantation rates (40.34%, 39.78% and 42.42% for traditional, short-term IVF and R-ICSI groups, respectively) were comparable in the three groups. The clinical pregnancy rates among traditional IVF group, short-term IVF group and R-ICSI group were 57.95%, 57.03% and 60.78%, respectively, and the difference among three groups didn't reach significance. CONCLUSION: The present study indicated that short insemination had no detrimental effects on clinical outcomes in human IVF and could prevent the occurrence of TFF combined with early rescue ICSI for high-risk patients of fertilization failure, which attained acceptable pregnancy outcomes. PMID- 29448848 TI - Development and characterization of morin hydrate-loaded micellar nanocarriers for the effective management of Alzheimer's disease. AB - The aim of this study was to prepare and characterise oral delivery of morin hydrate-loaded micellar nanocarriers using Pluronic P127 and Pluronic F123 for the effective management of Alzheimer's disease. After administration of formulation brain and blood drug concentration were found to be highest for optimised morin hydrate-loaded micellar nanocarriers as compared to plain morin hydrate. Significant (p < 0.05) reduction in assessed pharmacodynamic parameters was observed after administration of morin hydrate-loaded micellar nanocarriers as compared to disease control group. Chronic treatment with morin-loaded micelles significantly increased the memory in AlCl3 induced Alzheimer's disease in Wistar rats. PMID- 29448849 TI - Development of small-molecule immune checkpoint inhibitors of PD-1/PD-L1 as a new therapeutic strategy for tumour immunotherapy. AB - Cancer immunotherapy has been increasingly utilised to treat advanced malignancies. The signalling network of immune checkpoints has attracted considerable attention. Immune checkpoint inhibitors are revolutionising the treatment options and expectations for patients with cancer. The reported clinical success of targeting the T-cell immune checkpoint receptors PD-1/PD-L1 has demonstrated the importance of immune modulation. Indeed, antibodies binding to PD-1 or PD-L1 have shown remarkable efficacy. However, antibody drugs have many disadvantages, such as their production cost, stability, and immunogenicity and, therefore, small-molecule inhibitors of PD-1 and its ligand PD-L1 are being introduced. Small-molecule inhibitors could offer inherent advantages in terms of pharmacokinetics and druggability, thereby providing additional methods for cancer treatment and achieving better therapeutic effects. In this review, we first discuss how PD-1/PD-L1-targeting inhibitors modulate the relationship between immune cells and tumour cells in tumour immunotherapy. Second, we discuss how the immunomodulatory potential of these inhibitors can be exploited via rational combinations with immunotherapy and targeted therapy. Third, this review is the first to summarise the current clinical and preclinical evidence regarding small-molecule inhibitors of the PD-1/PD-L1 immune checkpoint, considering features and responses related to the tumours and to the host immune system.

PMID- 29448851 TI - Salvage tigecycline in high risk febrile neutropenic patients with hematological malignancies: a prospective multicenter study. AB - The purpose of this prospective, multi-center study was to examine the efficacy and safety of tigecycline as empirical treatment in neutropenic patients with hematological malignancies who failed to respond to first-line antibiotics. A total of 125 patients with persistent fever (>72 h) despite first-line antibiotics received empirical treatment with tigecycline (loading dose of 100 mg, followed by 50 mg every 12 h). The use of other antimicrobial agents was not restricted. Treatment success rate was 68.0%. Subgroup analysis revealed a success rate of 73.1% in patients with pneumonia and 35.3% in patients with bacteremia. Toxicities were moderate with gastrointestinal symptoms being the main side effects. In conclusion, tigecycline-based antibacterial regimen was a justifiable empirical treatment in febrile neutropenic patients who failed to respond to first-line antibiotics except those with bacteremia. For patients with bacteremia, trials on higher-dose of tigecycline are needed. PMID- 29448852 TI - Memantine in Japanese patients with moderate to severe Alzheimer's disease: meta analysis of multiple-index responder analyses. AB - BACKGROUND: Responder analyses assessing clinical worsening have attempted to clarify clinically meaningful drug efficacy enhancements in patients with Alzheimer's disease (AD). RESEARCH DESIGN AND METHODS: This was a meta-analysis of two multicenter, randomized, double-blind, parallel-group, 24-week studies of 633 Japanese patients with moderate to severe AD receiving memantine 20 mg/day (n = 318) or placebo (n = 315). The clinical trial registration number is UMIN000026013. RESULTS: Overall odds ratios (OR) for a reduced likelihood of clinical worsening (memantine versus placebo) were statistically significant on the following individual and combined rating scales: Severe Impairment Battery Japanese version (SIB-J, OR 0.52; 95% CI: 0.37, 0.73; p = 0.0001); Behavioral Pathology in AD Rating Scale (BEHAVE-AD, OR 0.53; 95% CI: 0.37, 0.75; p = 0.0003); and SIB-J + Clinician's Interview-Based Impression of Change-plus Japanese version (SIB-J + CIBIC-plus-J; OR 0.53; 95% CI: 0.37, 0.77; p = 0.0009). A significantly reduced risk of triple worsening was evident in the memantine versus placebo group on the combined SIB-J + CIBIC-plus-J + BEHAVE-AD rating scales (OR 0.38; 95% CI: 0.22, 0.65; p = 0.0003). CONCLUSIONS: Memantine is a viable treatment option for patients with AD presenting not only with cognitive impairment, but also with a broader range of symptoms, including the behavioral and psychological symptoms of dementia. PMID- 29448853 TI - Risk factors for positive margins after wide local excision of cutaneous squamous cell carcinoma. AB - BACKGROUND AND OBJECTIVES: The standard treatment for cutaneous squamous cell carcinoma (cSCC) is wide local excision (WLE). Incomplete tumor excision is associated with increased recurrence rates and mortality risk. Risk factors for positive margins after WLE of cSCC has been examined in only a few studies. We sought to assess the influence of several clinicopathological factors on margin status in the largest cSCC population to date. METHODS: We performed a retrospective review of records at two skin cancer clinics identifying patients with biopsy-proven cSCC who underwent WLE. We mined clinicopathological information for eligible subjects including age, gender, lesion location, immunosuppression, previous treatment, lesion size, biopsy type, tumor subtype, tumor thickness, degree of differentiation, ulceration and perineural invasion. RESULTS: A total of 1468 patients were eligible and 117 (8%) had positive margins after WLE. Older age at diagnosis (p = .011), lesion location on the head and neck (p < .001), previous treatment (p < .001), increased lesion diameter (p < .001), invasive subtype (p = .020) or increased tumor thickness (p < .001) were statistically significant risk factors for positive surgical margins. CONCLUSIONS: Our results present an opportunity to stratify cSCC patients into low- or high-risk for incomplete tumor clearance after WLE based on several clinicopathological factors. These findings should educate and inform the dermatologic surgeon's choice of primary management of cSCC. PMID- 29448854 TI - Mental health care providers talk about their experiences preventing suicide in people with substance use disorders in South Africa: implications for clinical practice. AB - OBJECTIVE: This study explored mental health care providers' experiences of preventing suicide in people with substance use disorders and their perceptions of factors related to clinical practice that contributed to these experiences. METHODS: In-depth, semistructured interviews were conducted with 18 mental health care providers working in South Africa. Thematic analysis was used to analyse the data inductively with Atlas.ti software. RESULTS: Participants described feeling hopeless, helpless, powerless and guilty and needed to debrief from their experiences of preventing suicide. They perceived their experiences to be related to the difficulties of treating substance use disorders, the difficulties of assessing and managing suicide risk and how treating substance use might increase suicide risk. CONCLUSIONS: The ways in which mental health care providers think about suicide and make sense of their experiences affects their perceived abilities to prevent suicide. Educating mental health care providers to transcend the limitations of risk factor approaches to suicide prevention and utilise evidence-based strategies for treating substance use disorders and associated problems, may be important to empower them and make them feel competent in suicide prevention. Empowering people with substance use disorders may help prevent suicide and may require collaboration between mental health care providers and allied professionals. PMID- 29448855 TI - Acute effects of blood flow restriction on exercise-induced free radical production in young and healthy subjects. AB - The main purpose of this study was to investigate the acute local and systemic effects of low-load resistance exercise (30% 1RM) with partial vascular occlusion on exercise-induced free radical production and to compare these effects with other established training methods. Fifteen young and healthy males (25 +/- 3 years) performed the following four sessions in a counterbalanced order on separate days: low-load resistance exercise (LI: 30% 1RM), low-load resistance exercise with blood flow restriction (LIBR: 30% 1RM), high-load resistance exercise (HI: 80% 1RM) and an additional session without exercise but blood flow restriction only (BR). Blood samples were obtained 15 min prior to and immediately after exercise sessions from the right index finger and first toe. To analyze concentrations of reactive oxygen species (ROS), electron paramagnetic resonance (EPR) spectroscopy was used. Additionally, mitochondrial ROS production was measured by adding inhibitors of electron transport chain complex III. There was an increased systemic ROS generation after the LIBR session from 0.837 +/- 0.093 to 0.911 +/- 0.099 umol/l/min. However, no local or systemic time * condition interaction was detected for ROS production. Regarding mitochondrial ROS production, results were not different between the conditions. Although the low-load resistance exercise session with partial vascular occlusion elicited systemic increases of ROS production, no significant changes were seen on a local level. We assume that this ROS concentration might not be high enough to induce cellular damage but is rather involved in muscle remodulation. However, this needs to be confirmed by future research. PMID- 29448856 TI - Study of target and non-target interplay in spatial attention task. AB - Selective visual attention is the ability to selectively pay attention to the targets while inhibiting the distractors. This paper aims to study the targets and non-targets interplay in spatial attention task while subject attends to the target object present in one visual hemifield and ignores the distractor present in another visual hemifield. This paper performs the averaged evoked response potential (ERP) analysis and time-frequency analysis. ERP analysis agrees to the left hemisphere superiority over late potentials for the targets present in right visual hemifield. Time-frequency analysis performed suggests two parameters i.e. event-related spectral perturbation (ERSP) and inter-trial coherence (ITC). These parameters show the same properties for the target present in either of the visual hemifields but show the difference while comparing the activity corresponding to the targets and non-targets. In this way, this study helps to visualise the difference between targets present in the left and right visual hemifields and, also the targets and non-targets present in the left and right visual hemifields. These results could be utilised to monitor subjects' performance in brain-computer interface (BCI) and neurorehabilitation.

PMID- 29448858 TI - Long-term results of the AIEOP MH'96 childhood Hodgkin's lymphoma trial and focus on significance of response to chemotherapy and its implication in low risk patients to avoid radiotherapy. AB - Identify a subset of early-stage HL children (GR1) curable with limited chemotherapy+/-radiotherapy; improve outcome of intermediate (GR2) and high-risk (GR3) patients; establish impact of response to chemotherapy evaluated with conventional imaging (CI). One hundred and sixty GR1-patients received 3ABVD + involved-field (IF) low-dose (LD) (20 Gy) irradiation if mediastinal mass or partial response (PR) after chemotherapy. Eighty-five GR2- and 315 GR3-patients received 4 and 6 COPP/ABV + IFRT, respectively. The 63 GR1 patients spared from radiotherapy had 15-year survival and EFS of 100 and 84.5%, respectively. The GR2 and GR3 15-year FFP were 84.7 and 78.6%, respectively. No different prognosis for patients in CR or PR evaluated during and after chemotherapy was observed. In conclusion, low-risk patients in CR may be successfully treated with radiation free, low-intensity chemotherapy. Good, but less satisfactory, results were registered in GR2 and GR3. Response evaluated with CI is not a prognostic factor, but permits identification of low-risk patients who can avoid radiotherapy. PMID- 29448859 TI - Assessment of the external validity of the American Joint Committee on Cancer 8th staging system for anal carcinoma. AB - BACKGROUND: The current study evaluates the prognostic value of the 8th edition of the American Joint Committee on Cancer (AJCC) staging system for patients with anal carcinoma. PATIENTS AND METHODS: The Surveillance, Epidemiology and End Results (SEER) database (2004-2014) was explored and AJCC 6th and 8th stages were formulated. Through Kaplan-Meier analysis, overall survival analyses were performed. The Cox regression model (adjusted for age, gender, histology, ethnicity, subsite and grade) was calculated for cancer-specific survival and, subsequently, pairwise comparisons of hazard ratios were calculated. RESULTS: A total of 11,934 anal carcinoma patients were included in the analysis. Overall survival was compared according to both AJCC 6th and 8th systems. For both staging systems, the p value for the trend in overall survival was significant (p < .0001). Nevertheless, for the AJCC 6th system, stage IIIA and IIIB curves were overlapping; while for the AJCC 8th system, the median survival for stage IIB was lower than the mean survival for stage IIIA (74 months vs. 96 months). Moreover, stage IIIB and stage IIIC curves were overlapping. The cause-specific (cancer specific) Cox regression hazard was calculated for both staging systems. Pairwise hazard ratio comparisons between different AJCC 6th stages were performed and all p values for comparisons were significant (p < .05). Pairwise hazard ratio comparisons between different AJCC 8th stages were performed and only the following comparisons were significant (p < .0001) (I vs. IIA; IIA vs. IIB; IIIC vs. IV). The C-statistic (using death from anal carcinoma as the dependent variable) for the AJCC 6th staging system was: 0.681 (SE: 0.009; 95% CI: 0.664 0.698); while the C-statistic for the AJCC 8th staging system was 0.687 (SE: 0.008; 95% CI: 0.670-0.703). CONCLUSIONS: There is no evidence of significant improvement in the AJCC 8th edition compared to AJCC 6th (or 7th) edition in terms of overall or cancer-specific survival prediction. PMID- 29448860 TI - Therapeutic ionizing radiation induced bone loss: a review of in vivo and in vitro findings. AB - Radiation therapy is one of the routine treatment modalities for cancer patients. Ionizing radiation (IR) can induce bone loss, and consequently increases the risk of fractures with delayed and nonunion of the bone in the cancer patients who receive radiotherapy. The orchestrated bone remodeling can be disrupted due to the affected behaviors of bone cells, including bone mesenchymal stem cells (BMSCs), osteoblasts and osteoclasts. BMSCs and osteoblasts are relatively radioresistant compared with osteoclasts and its progenitors. Owing to different radiosensitivities of bone cells, unbalanced bone remodeling caused by IR is closely associated with the dose absorbed. For doses less than 2 Gy, osteoclastogenesis and adipogenesis by BMSCs are enhanced, while there are limited effects on osteoblasts. High doses (>10 Gy) induce disrupted architecture of bone, which is usually related to decreased osteogenic potential. In this review, studies elucidating the biological effects of IR on bone cells (BMSCs, osteoblasts and osteoclasts) are summarized. Several potential preventions and therapies are also proposed. PMID- 29448861 TI - Self-retaining barbed suture reduces warm ischemia time during laparoscopic partial nephrectomy. AB - OBJECTIVE: To evaluate the efficacy and safety of self-retaining barbed suture in renorrhaphy during laparoscopic partial nephrectomy by comparing surgical outcomes in a prospective randomized manner. MATERIAL AND METHODS: From July 2014 to July 2015, a total of 60 patients with T1 renal tumor were randomized into two equal groups: self-retaining barbed suture (SRBS) and conventional absorbable polyglactin suture (non-SRBS group). All patients were treated by retroperitoneal laparoscopic partial nephrectomy. One surgeon with high volume experience performed all procedures. The patient demographics and perioperative outcomes were compared. RESULTS: The patient demographics and tumor characteristics were comparable. The mean tumor size and R.E.N.A.L. scores were comparable between the two groups. LPN was successfully accomplished in all patients without open conversion. The warm ischemia and renorrhaphy times were significantly shorter in the SRBS group (18.8 +/- 8.2 vs. 22.9 +/- 7.3 min, P = .04; 10.4 +/- 3.7 vs. 13.8 +/- 5.6 min, P = .01). The minor complication rate was 13.3% vs. 10.0%, which was comparable. No major complication occurred. CONCLUSIONS: The randomized controlled trial demonstrates that SRBS for renorrhaphy during retroperitoneal laparoscopic partial nephrectomy is safe and efficient. Application of barbed suture simplifies the parenchymal repair procedure and reduces warm ischemia time in comparison with conventional suture. PMID- 29448862 TI - Filgotinib for the treatment of Crohn's disease. AB - INTRODUCTION: Inflammatory bowel diseases, such as Crohn's disease (CD) and ulcerative colitis (UC), are widespread diseases (with an estimated 2.2 million Europeans affected), and even populations previously considered 'low risk' (such as Japan and India) are witnessing an increasing incidence. CD is a chronic, progressive immunologically driven disease, with an evolution characterized by succession of periods of progression and remission. New physiopathological pathways are continuously being discovered, the more we understand about how the disease appears and progresses, the more targets become available for the development of novel therapies. Areas covered: Filgotinib is one of these promising new therapies; this article discusses the currently available data. We used an exhaustive search of the PubMed database to corroborate information regarding its chemical characteristics, and the studies evaluating clinical efficacy and safety. Expert opinion: Up to now, the phase-II study evaluating Filgotinib yielded very promising results in moderate to severe CD patients, with good clinical response, mucosal healing, while having few and moderate adverse effects, both in anti-TNF naive and resistant patients. Phase-III studies are still ongoing and will help decide whether Filgotinib will be a worthwhile drug in the treatment of CD and the best way to use it. PMID- 29448863 TI - Mental health literacy, sub-clinical personality disorders and job fit. AB - BACKGROUND: This study looked at lay theories of how people with sub-clinical personality disorders experience the world of work. AIMS: The aim was to investigate the paradox that subclinical and clinical personality disorders are seen as beneficial for success, rather than a handicap in certain jobs. METHODS: In all, 230 participants read 14 vignettes derived from Oldham and Morris's book describing DSMIII personality disorders for a popular audience. Participants were invited to suggest what type of work each disordered person may be successful at, as well as six ratings of their social adjustment. RESULTS: There was a tendency for people to believe those with OCD to be suited to Accountancy, Narcissism and Paranoia to General Management, Histrionic PD to being an Actor and Schizotypal an Artist. Surprisingly Paranoid and Sadistic people were judged to be good managers and Histrionic, Passive Aggressive and Schizotypal the worst. People in Cluster C were judged as best managers, but those in Cluster B as better adjusted. CONCLUSIONS: Results show that lay people believe that certain "dark side" traits associated with personality disorders, particularly dependency and OCD, are thought to be beneficial for success, rather than failure, in many jobs. PMID- 29448864 TI - Development of a novel 6-DOF parallel mechanism moving platform for investigating the effects of multimodal sensory feedback information regarding postural stability in humans. AB - The purpose of this study was to develop a six-degree-of-freedom parallel mechanism moving platform to investigate the effects of multimodal sensory feedback information while standing upright. We constructed a custom-designed disturbance-applying instrument (DAI) consisting of a support surface suspended from eight pneumatic artificial muscles. The posture of the support surface was controlled with a proportional-integral-derivative (PID) feedback system using an infra-red camera-based real-time 3D motion capture system, and was estimated by step and frequency responses. Head trajectories of two healthy subjects were recorded to evaluate the effect of the differences in the impedance of the support surface during upright standing with their eyes opened/closed. The results demonstrated that the step and frequency responses of the DAI were good enough to enhance the bodily oscillation and head motion relative to the support surface. Indeed, the head-swaying space, using the DAI in a 0.2-Hz air-supplying condition during upright standing with their eyes closed, was larger than in the other standing condition. These results suggest that the specific medio-lateral head swaying was caused by the effects of the multimodal sensory feedback information using the DAI. In conclusion, we developed a novel moving platform to investigate the effects of multimodal sensory feedback information upon upright postural control. The DAI would be particularly valuable to enhance the head swaying space during upright standing by changing the impedance of the support surface or stimulating the translational and/or rotational sensory feedback integration. PMID- 29448865 TI - Diagnostic accuracy of three screening questions (3Q/TMD) in relation to the DC/TMD in a specialized orofacial pain clinic. AB - OBJECTIVE: To determine the diagnostic accuracy of three screening questions (3Q/TMD) in relation to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD), in a specialized clinic. MATERIAL AND METHODS: Consecutive patients, >18 years, referred with a possible TMD complaint to the Orofacial Pain and Dysfunction clinic, Academic Centre for Dentistry Amsterdam, the Netherlands, were included in the study. All patients (n = 449; mean age 44 years; 72% females), answered the 3Q/TMD and the DC/TMD questionnaire before a DC/TMD examination. The 3Q/TMD constitutes of two questions on weekly pain from the jaw, face and temple region (Q1), and on function (Q2), and one function-related question on weekly catching and/or locking of the jaw (Q3). Q1 and Q2 were evaluated in relation to a DC/TMD pain diagnosis and Q3 in relation to a subgroup of DC/TMD intra-articular diagnosis, referred to as the reference standard. RESULTS: In total, 44% of patients received a pain-related DC/TMD diagnosis and 33% an intra-articular reference DC/TMD diagnosis. Sensitivity for the two pain screening questions was high (0.83-0.94), whereas specificity was low (0.41 0.55). For the function-related question, sensitivity was low (0.48), whereas specificity was high (0.96). CONCLUSIONS: In a specialized pain clinic, the two pain questions (Q1, Q2) are positive in most patients with pain-related TMD. Therefore, in case of a positive response, further diagnostic procedures for TMD pain are warranted. For the functional screening question (Q3), a positive response is indicative for an intra-articular DC/TMD diagnosis, while in case of a negative outcome, an intra-articular TMD might still be present. PMID- 29448866 TI - Multifunctional mesoporous silica nanoparticles as efficient transporters of doxorubicin and chlorin e6 for chemo-photodynamic combinatorial cancer therapy. AB - A multimodal nanocarrier based on mesoporous silica nanoparticles (MSNs) is developed to co-delivery photosensitizer chlorin e6 (Ce6) and chemotherapeutic agent doxorubicin (Dox) for cancer combination therapy. Ce6 was covalently conjugated with mesoporous silica nanoparticles, which could increase the loading efficiency, and allowed for photodynamic therapy. Doxorubicin was loaded into the pores of mesoporous silica nanoparticles to afford the dual drug delivery system Dox@MSNs-Ce6. These hybrid nanoparticles have an average diameter of about 100 nm and slightly negative charge of about -17 mV. The Dox@MSNs-Ce6 nanoparticles could efficiently enter into cancer cells. The cellular reactive oxygen species level in treated cells increased about 17 times, upon 660 nm light irradiation (10 mW/cm2, 2 min). More importantly, Dox@MSNs-Ce6 exhibited excellent synergistic effect through combining chemotherapy and photodynamic therapy against A549 lung cancer cells. Our work provides an effective strategy for anticancer drug delivery and combination therapy. PMID- 29448867 TI - Comparison of the knitted silk vascular grafts coated with fibroin sponges prepared using glycerin, poly(ethylene glycol diglycidyl ether) and poly(ethylene glycol) as porogens. AB - Development of a small-diameter artificial vascular graft is urgent because existing materials often occlude within a short time. We have shown that small diameter vascular graft using Bombyx mori silk fibroin is a potential candidate. Silk fibroin grafts are fabricated by coating silk fibroin on the knit tube prepared from silk fibroin fibers. However, there is a serious problem that the coated silk fibroin portion hardens when alcohol is used for insolubilization of the coated silk fibroin. This hardening prevents the desired biodegradation of the coated silk fibroin. In this study, we improved the silk fibroin coating method of the knit silk fibroin tube. Namely, the silk fibroin sponge coating was performed using glycerin, poly(ethylene glycol diglycidyl ether) or poly(ethylene glycol). In addition, silk fibroin grafts were prepared avoiding dryness during the coating process and were kept in the hydrated state until implantation into the abdominal aorta was complete. After implantation of the hydrated silk fibroin grafts, grafts were taken out at two weeks or three months, and histopathological examination was performed. The grafts coated with three types of silk fibroin sponges had a higher tissue infiltration rate than alcohol-treated grafts and were superior in the formation of smooth muscle cell and vascular endothelial cell remodeling. Biodegradations of the silk fibroin grafts prepared using the three types of silk fibroin sponge coatings and alcohol-treated silk fibroin grafts were also examined with protease XIV in vitro, and the grafts were observed by scanning electron microscopy before and 24 h after biodegradation. Faster biodegradations were observed for grafts coated with the three types of silk fibroin sponges. 13C solid-state nuclear magnetic resonance studies showed that the conformation of the silk fibroin sponge prepared using porogen was a random coil with high mobility in the hydrated state. We believe that small diameter silk fibroin vascular grafts coated with quick biodegradable silk fibroin sponges can be developed based on these findings.

PMID- 29448869 TI - Development and validation of probe drug cocktails for the characterization of CYP450-mediated metabolism by human heart microsomes. AB - 1. The objective of our study was to develop and validate a cocktail approach to allow the simultaneous characterization of various CYP450-mediated oxidations by human heart microsomes for nine probe drug substrates, namely, 7-ethoxyresorufin, bupropion, repaglinide, tolbutamide, bufuralol, chlorzoxazone, ebastine, midazolam and dodecanoic acid. 2. The first validation step was conducted using recombinant human CYP450 isoenzymes by comparing activity measured for each probe drug as a function of (1) buffer used, (2) selectivity towards specific isoenzymes and (3) drug interactions between probes. Activity was all measured by validated LC-MSMS methods. 3. Two cocktails were then constituted with seven of the nine drugs and subjected to kinetic validation. Finally, all probe drugs were incubated with human heart microsomes prepared from ventricular tissues obtained from 12 patients undergoing cardiac transplantation. 4. Validated cocktail #1 including bupropion, chlorzoxazone, ebastine and midazolam was used to characterize CYP2B6-, 2E1-, 2J2- and 3A5-mediated metabolism in human hearts. 5. Cocktail #2 which includes bufuralol, 7-ethoxyresorufin and repaglinide failed the validation step. Substrates in cocktail #2 as well as tolbutamide and dodecanoic acid had to be incubated separately because of their physico-chemical characteristics (solubility and ionization) or drug interactions. 6. Activity in HHM was the highest towards ebastine, chlorzoxazone and tolbutamide. PMID- 29448870 TI - A new assessment tool for ulnar drift in patients with rheumatoid arthritis using pathophysiological parameters of the metacarpophalangeal joint. AB - OBJECTIVES: To establish a new assessment tool for ulnar drift (UD) in rheumatoid arthritis (RA). METHODS: We established an observational cohort of 67 patients (134 rheumatoid hands) beginning in 2004. Fifty-two patients (100 hands) had follow-up in 2009 and 37 patients (63 hands) completed follow-up in 2015. UD was evaluated with the Fearnley classification and our scoring method, which assesses four parameters of the metacarpophalangeal joint. Cluster analysis using UD parameters divided hands into groups. Changes in UD over time, correlation of the Fearnley stage and cluster with a functional assessment, and reliability of the parameters were analyzed. RESULTS: UD increased and worsened over time according to the trend test. A dendrogram indicated five clusters would be appropriate. Both the Fearnley classification and cluster were associated with function; however, our method related to function more linearly (R-squared: 0.42). We found one type of hand in which bone destruction precedes the joint dislocation and one type in which joint dislocation progresses with little deviation during UD progression. CONCLUSION: Our UD evaluation appeared to be simple and related to function. Additionally, it enables dividing UD hands into five stages. Thus, our assessment should be beneficial compared to the Fearnley classification in considering treatments of UD. PMID- 29448871 TI - Interactions of organophosphorus pesticides with solute carrier (SLC) drug transporters. AB - 1. Organophosphorus pesticides (OPs) are known to interact with human ATP-binding cassette drug efflux pumps. The present study was designed to determine whether they can also target activities of human solute carrier (SLC) drug transporters. 2. The interactions of 13 OPs with SLC transporters involved in drug disposition, such as organic cation transporters (OCTs), multidrug and toxin extrusion proteins (MATEs), organic anion transporters (OATs) and organic anion transporting polypeptides (OATPs), were mainly investigated using transporter overexpressing cell clones and fluorescent or radiolabeled reference substrates. 3. With a cut-off value of at least 50% modulation of transporter activity by 100 uM OPs, OAT1 and MATE2-K were not impacted, whereas OATP1B1 and MATE1 were inhibited by two and three OPs, respectively. OAT3 activity was similarly blocked by three OPs, and was additionally stimulated by one OP. Five OPs cis-stimulated OATP2B1 activity. Both OCT1 and OCT2 were inhibited by the same eight OPs, including fenamiphos and phosmet, with IC50 values however in the 3-30 uM range, likely not relevant to environmental exposure. 4. These data demonstrated that various OPs inhibit SLC drug transporter activities, especially those of OCT1 and OCT2, but only when used at high concentrations not expected to occur in environmentally-exposed humans. PMID- 29448873 TI - Comparison of Self-Reported and Behavioral Pain Assessment Tools in Critically Ill Patients. AB - BACKGROUND: Self-reported and behavioral pain assessment scales are often used interchangeably in critically ill patients due to fluctuations in mental status. The correlation between scales is not well elucidated. The purpose of this study was to describe the correlation between self-reported and behavioral pain scores in critically ill patients. METHODS: Pain was assessed using behavioral and self reported pain assessment tools. Behavioral pain tools included Critical Care Pain Observation Tool (CPOT) and Behavioral Pain Scale (BPS). Self-reported pain tools included Numeric Rating Scale (NRS) and Wong-Baker Faces Pain Scales. Delirium was assessed using the confusion assessment method for the intensive care unit. Patient preference regarding pain assessment method was queried. Correlation between scores was evaluated. RESULTS: A total of 115 patients were included: 67 patients were nondelirious and 48 patients were delirious. The overall correlation between self-reported (NRS) and behavioral (CPOT) pain scales was poor (0.30, P = .018). In patients without delirium, a strong correlation was found between the 2 BPSs (0.94, P < .0001) and 2 self-reported pain scales (0.77, P < .0001). Self-reported pain scale (NRS) and BPS (CPOT) were poorly correlated with each other (0.28, P = .021). In patients with delirium, there was a strong correlation between BPSs (0.86, P < .0001) and a moderate correlation between self-reported pain scales (0.69, P < .0001). There was no apparent correlation between self-reported (NRS) and BPSs (CPOT) in patients with delirium (0.23, P = .12). Most participants preferred self-reported pain assessment. CONCLUSION: Self reported pain scale and BPS cannot be used interchangeably. Current validated BPSs may not accurately reflect self-reported pain in critically ill patients. PMID- 29448872 TI - Emotional Well-Being and Public Health: Proposal for a Model National Initiative. AB - In 2011, the National Prevention, Health Promotion, and Public Health Council named mental and emotional well-being as 1 of 7 priority areas for the National Prevention Strategy. In this article, we discuss emotional well-being as a scientific concept and its relevance to public health. We review evidence that supports the association between emotional well-being and health. We propose a national emotional well-being initiative and describe its 6 components: systematic measurement of emotional well-being, identification of the drivers of emotional well-being, formation of partnerships with diverse stakeholders, implementation and dissemination of evidence-based interventions to promote emotional well-being and its drivers, development of public health messaging, and identification of and strategies to address disparities in emotional well-being and its drivers. Finally, we discuss ways in which a national emotional well being initiative would complement current public health efforts and the potential challenges to such an initiative. PMID- 29448874 TI - Autobiographical memory functions and posttraumatic stress symptoms across adulthood. AB - Previous research has documented robust individual differences in the functions served by autobiographical memories, and shown that different autobiographical memory functions are related to both positive and negative indicators of psychological well-being, and that their frequency varies with age. In this study, we examined the unique relationship between autobiographical memory functions and posttraumatic stress symptoms (PTSS) and whether such relationships varied with age across adulthood. A representative sample of 1040 adult Danes (20 70 years old) reported the frequency with which they recall autobiographical memories for different purposes as well as their level of posttraumatic stress disorder (PTSD) symptoms. Higher reflective and ruminative functions, as well as lower social function, predicted higher levels of PTSS. There were no moderating effects of age. The results suggest that although the frequency of various autobiographical functions varies throughout the adult years, their association with PTSS is similar across adulthood. PMID- 29448875 TI - Screening for cognitive impairment in an Australian aged care assessment team as part of comprehensive geriatric assessment. AB - Accurate detection of mild cognitive impairment (MCI) is important to stratify and address risk. Yet, few short cognitive screening instruments are validated for this. . In Australia, all clients referred to an Aged Care Assessment Team (ACAT) receive comprehensive geriatric assessment (CGA) including the Standardized Mini-Mental State Examination (SMMSE). We compared the accuracy of the quick mild cognitive impairment (Qmci) screen to the SMMSE in 283 participants: 195 with dementia, 47 with MCI, and 41 with subjective cognitive decline (SCD) in an Australian community-based ACAT. Both had similar accuracy in identifying dementia, AUC of 0.86 for the Qmci versus 0.93 for the SMMSE (p = 0.10), but the Qmci was more accurate than the SMMSE in differentiating MCI from SCD, AUC of 0.84 versus 0.71, respectively, p = 0.046. These suggest that the new, short (3-5 min) Qmci screenis appropriate for use in an ACAT or other units conducting CGA. PMID- 29448876 TI - Evaluation of injectable anaesthesia with five medetomidine-midazolam based combinations in Egyptian fruit bats ( Rousettus aegyptiacus). AB - Egyptian fruit bats are increasingly used as model animals in neuroscience research. Our aim was to characterize suitable injectable anaesthesia for this species, possibly replacing inhalant anaesthesia, thus minimizing occupational health hazards. Eight bats were randomly assigned by a crossover design for subcutaneously administered combinations of medetomidine-midazolam with: saline (MM-Sal), ketamine (MM-Ket), fentanyl (MM-Fen), morphine (MM-Mor), or butorphanol (MM-But). The anaesthetic depth and vital signs were monitored at baseline and every 10 min until bats recovered. If after 180 min the bats did not recover, atipamezole was administered. Mean induction times were 7-11.5 min with all combinations. Twitching during induction was common. All combinations produced anaesthesia, with significantly decreased heart rate (from 400 to 200 bpm) and respiratory rate (from 120-140 to 36-65 rpm). Arrhythmia and irregular breathing patterns occurred. MM-Fen, MM-Mor, and MM-But depressed respiration significantly more than MM-Sal. Time to first movement with MM-Ket and MM-But lasted significantly longer than with MM-Sal. Recovery time was significantly shorter in the MM-Sal (88 min) in comparison to all other treatments, and it was significantly longer in the MM-But (159 min), with atipamezole administered to four of the eight bats. In conclusion, all five anaesthetic protocols are suitable for Egyptian fruit bats; MM-Ket produces long anaesthesia and minimal respiratory depression, but cannot be antagonized completely. MM-Fen, MM-Mor, and MM-But depress respiration, but are known to produce good analgesia, and can be fully antagonized. Administration of atipamezole following the use of MM-But in Egyptian fruit bats is recommended.

AB - OBJECTIVE: In this study, the three-dimensional (3D) modification of root canal curvature was measured, after the application of Reciproc instrumentation technique, by using cone beam computed tomography (CBCT) imaging and a special algorithm developed for the 3D measurement of the curvature of the root canal. MATERIALS AND METHODS: Thirty extracted upper molars were selected. Digital radiographs for each tooth were taken. Root curvature was measured by using Schneider method and they were divided into three groups, each one consisting of 10 roots, according to their curvature: Group 1 (0 degrees -20 degrees ), Group 2 (21 degrees -40 degrees ), Group 3 (41 degrees -60 degrees ). CBCT imaging was applied to each tooth before and after its instrumentation, and the data were examined by using a specially developed CBCT image analysis algorithm. RESULTS: The instrumentation with Reciproc led to a decrease of the curvature by 30.23% (on average) in all groups. CONCLUSIONS: The proposed methodology proved to be able to measure the curvature of the root canal and its 3D modification after the instrumentation. PMID- 29448878 TI - A method for preventive intervention regarding temporomandibular pain and dysfunction. AB - OBJECTIVE: Adolescent girls frequently suffer from temporomandibular disorder (TMD) symptoms and associated headache. A program aimed at informing about risk behavior for TMD symptoms, how to influence harmful habits and about general relaxation was tested. MATERIAL AND METHODS: Eighty girls at two high schools, 16 years of age, with or without symptoms, were invited to the health information on two occasions and 60 girls participated. Firstly, a questionnaire regarding symptoms and oral parafunctional habits was administrated. Structured information was given about the normal anatomy and function of muscles and joints, about the occlusion, oral habits and symptoms of orofacial pain/dysfunction and headache. General relaxation was instructed and trained. At a three-month follow-up, the same questionnaire regarding symptoms as at baseline was completed. RESULT: The information provided was perceived as useful and instructive. At the follow-up, 77% reported that they used what they had learned. Headache once a week or more decreased from 49% at baseline to 35% and headache 'never/rarely' changed from 11% to 25% (p = .002). Reported joint sounds had decreased by the follow-up (p = .053), as had the use of chewing gum (p = .002). A majority of the girls suggested that the information should be scheduled during school hours. CONCLUSION: Health information about the jaw system can influence risk factors for TMD symptoms and the frequency of symptoms among adolescent girls.

AB - Purpose Using a mixed-methods formative evaluation, the purpose of this study was to provide a broad overview of the Alabama eHealth programme set-up and initial patient outcomes. The Alabama eHealth programme uses telemedicine to provide medical care to people living with HIV in rural Alabama. It was led by a community-based organisation, Medical Advocacy and Outreach (MAO), and supported by AIDS United and the Corporation for National Community Service's Social Innovation Fund with matching support from non-federal donors. Methods We conducted and transcribed in-depth interviews with Alabama eHealth staff and then performed directed content analysis. We also tracked patients' ( n = 240) appointment attendance, CD4 counts, and viral loads. Findings Staff described the steps taken to establish the programme, associated challenges (e.g., costly, inadequate broadband in rural areas), and technology enabling this programme (electronic medical records, telemedicine equipment). Of all enrolled patients, 76% were retained in care, 88% had antiretroviral therapy and 75% had a suppressed viral load. Among patients without missing data, 96% were retained in care, 97% used antiretroviral therapy and 93% had suppressed viral loads. There were no statistically significant demographic differences between those with and without missing data. Conclusions Patients enrolled in a telemedicine programme evaluation successfully moved through the HIV continuum of care. PMID- 29448880 TI - Migration and clinical outcome of mobile-bearing versus fixed-bearing single radius total knee arthroplasty. AB - Background and purpose - Mobile-bearing total knee prostheses (TKPs) were developed in the 1970s in an attempt to increase function and improve implant longevity. However, modern fixed-bearing designs like the single-radius TKP may provide similar advantages. We compared tibial component migration measured with radiostereometric analysis (RSA) and clinical outcome of otherwise similarly designed cemented fixed-bearing and mobile-bearing single-radius TKPs. Patients and methods - RSA measurements and clinical scores were assessed in 46 randomized patients at baseline, 6 months, 1 year, and annually thereafter up to 6 years postoperatively. A linear mixed-effects model was used to analyze the repeated measurements. Results - Both groups showed comparable migration (p = 0.3), with a mean migration at 6-year follow-up of 0.90 mm (95% CI 0.49-1.41) for the fixed bearing group compared with 1.22 mm (95% CI 0.75-1.80) for the mobile-bearing group. Clinical outcomes were similar between groups. 1 fixed-bearing knee was revised for aseptic loosening after 6 years and 2 knees (1 in each group) were revised for late infection. 2 knees (1 in each group) were suspected for loosening due to excessive migration. Another mobile-bearing knee was revised after an insert dislocation due to failure of the locking mechanism 6 weeks postoperatively, after which study inclusion was preliminary terminated. Interpretation - Fixed-bearing and mobile-bearing single-radius TKPs showed similar migration. The latter may, however, expose patients to more complex surgical techniques and risks such as insert dislocations inherent to this rotating-platform design. PMID- 29448881 TI - Outcomes of multitarget therapy using mycophenolate mofetil and tacrolimus for refractory or relapsing lupus nephritis. AB - Objectives Outcomes of systemic lupus erythematosus (SLE) have significantly improved over the years. However, when there is major organ involvement, the outcomes can still be unfavorable. Outcomes of multitarget therapy using mycophenolate mofetil (MMF) and tacrolimus in patients with SLE who were refractory to standard therapy were assessed. Methods We retrospectively reviewed the Hanyang BAE lupus cohort to identify patients with biopsy-confirmed lupus nephritis (classes III, IV, or V) who failed to either achieve complete response with standard induction therapy or those who had a lupus flare after achieving a complete response with conventional induction therapy and subsequently were switched to multitarget combination therapy with MMF and tacrolimus. Outcomes, including renal response, proteinuria, glomerular filtration rate, serum albumin, anti-dsDNA antibody level, Systemic Lupus Erythematosus Disease Activity Index (SLEDAI), and complements, were assessed at six and 12 months. Results Twenty nine patients, including 12 who failed to achieve a complete response at 12 months after initial conventional induction therapy and 17 with lupus flare after achieving a complete response at 12 months and treated with multitarget therapy, were included in the analysis. At six months, 53.9% of the patients showed a response, with 15.4% of patients showing a complete response and 38.5% of patients showing a partial response. At 12 months, 55.5% of patients exhibited a response (with complete and partial response in 25.9% and 29.6%, respectively). The dosage of steroids was significantly decreased at six months compared with baseline and was maintained at 12 months. Proteinuria, anti-double-stranded DNA antibody positivity, as well as C3 and C4 levels improved after treatment and persisted until 12 months, but were not significant. SLEDAI also improved. Outcomes were significantly better in patients who had a complete response but later had a flare, resulting in the use of multitarget therapy and achieving a subsequent complete response. Conclusions Multitarget therapy with MMF and tacrolimus can be a reasonable option in refractory lupus nephritis patients who failed to show adequate response to conventional induction therapy or who had flares during maintenance therapy. This treatment can help patients achieve a renal response and reduce the use of steroids. PMID- 29448882 TI - Multitarget therapy of mycophenolate mofetil and cyclosporine A for induction treatment of refractory lupus nephritis. AB - Standard induction therapy for lupus nephritis (LN) with mycophenolate mofetil (MMF) or cyclophosphamide (CYC) is often ineffective. Evidence on rescue induction regimens is scarce. We analyzed efficacy and tolerability of multitarget immunosuppression with MMF and cyclosporine A (CsA) as induction treatment for LN (class III/IV/V) refractory to CYC and/or MMF. We included all six refractory LN patients (class IV = 3, class V = 2, class III = 1) from our 400-patient tertiary Lupus Clinic observed between 2012 and 2015. Four patients had previously received pulse CYC. All six received MMF as first or second induction therapy and CsA was added once failure to reach remission was established. Daily dose of MMF was 2-3 g and CsA was dosed up to 2.6-3.7 mg/kg/day. Mean proteinuria was reduced from 2407 mg/24 hours at the start of the MMF+CsA regimen to 544 mg/day after six months. The mean prednisolone dose was reduced from 17.5 to 6 mg/day after six months of MMF+CsA. Four patients achieved a complete renal response, one patient had a partial renal response and one failed to respond. None of the patients presented with adverse events. These data suggest that adding CsA to MMF can induce complete remission of refractory LN and is well tolerated. PMID- 29448883 TI - Natural Frequencies Do Foster Public Understanding of Medical Tests: Comment on Pighin, Gonzalez, Savadori, and Girotto (2016). AB - Patients and doctors often need to make decisions based on the results of medical tests. When these results are presented in the form of conditional probabilities, even doctors find it difficult to interpret them correctly. There is over 20 y of research supporting the finding that people are better able to calculate the correct positive predictive value of a test when given information in natural frequencies, as opposed to conditional probabilities. Natural frequencies are one of a few psychological tools that have made it into evidence-based medicine. Recently, Pighin and others (Med Decis Making 2016;36:686-91) argued that natural frequencies could hinder informed decision making, a critique based on a single task and a crude scoring criterion we refer to as the 50%-Split. Our commentary addresses these criticisms based on three analyses. First, we show how the 50% Split scoring used by Pighin and others misclassifies known errors, such as solely attending to the hit rate (true-positive rate) of the test, as strategies that support understanding. Second, we reanalyze data from 21 additional problems completed by various participant groups to show that their scoring criterion does not support their results in 19 out of 21 cases. Third, we apply the mean deviation scoring method and show that, when given information in natural frequency formats, participants provide estimates that are closer to the correct Bayesian solution than for conditional probability formats. In each analysis, natural frequencies lead to more correct judgements and therefore promote informed decision making relative to conditional probabilities. We welcome further discussions of performance metrics that can provide insight into how the public and therefore patients understand the implications of medical test results. PMID- 29448884 TI - Ameliorating the in vivo antimalarial efficacy of artemether using nanostructured lipid carriers. AB - Cerebral malaria (CM) is a fatal neurological complication of Plasmodium falciparum infection that affects children (below five years old) in sub-Saharan Africa and adults in South-East Asia each year having the fatality rate of 10 25%. The survivors of CM also have high risk of long term neurological or cognitive deficits. The objective of the present investigation was to develop optimised nanostructured lipid carriers (NLCs) of artemether (ARM) for enhanced anti-malarial efficacy of ARM. NLCs of ARM were prepared by a combination of high speed homogenisation (HSH) and probe sonication techniques. Preliminary solubility studies for ARM showed highest solubility in trimyristin (solid lipid), capmul MCM NF (liquid lipid) and polysorbate 80 (surfactant). Trimyristin and capmul showed superior miscibility at a ratio of 70:30.The optimised NLC formulation has the particle size (PS) of: 48.59 +/- 3.67 nm, zeta potential (ZP) of: -32 +/- 1.63 mV and entrapment efficiency (EE) of: 91 +/- 3.62%. In vitro cell line (human embryonic kidney fibroblast cell line (HEK 293 T)) cytotoxicity studies showed that prepared formulation was non-toxic. The results of in vivo studies in CM induced mice prevented the recrudescence of parasite after administration of NLCs of ARM. Additionally, NLCs of ARM showed better parasite clearance, higher survival (60%) in comparison to ARM solution (40%). Also it was observed that lesser entrapment of Evans blue stain (prepared in PBS as solution) in the NLCs of ARM treated brains of C57BL/6 mice than ARM solution treated mice. Hence NLCs of ARM may be a better alternative for improving therapeutic efficacy than ARM solution. PMID- 29448885 TI - "Recognize Our Humanity": Immigrant Youth Voices on Health Care in Arizona's Restrictive Political Environment. AB - The "DACAmented Voices in Healthcare" project examined the intersection of restrictive immigration policies and health care via photovoice, a participatory action research approach, with immigrant youth living in Arizona, who were recipients of the Deferred Action for Childhood Arrivals (DACA) program. These "DACAmented" youth took part in nine photovoice sessions exploring their health care experiences and accessibility to care using documentary photography and narratives. They poignantly illustrated their experiences through images identifying their main health concerns and strengths, facilitating the development of health policy recommendations. This article illustrates the thematic findings and discusses policy recommendations and lessons learned from presentations to policy makers and health care providers. Findings suggest that immigrant youth are knowledgeable of their family's health care needs and hold a unique and important position within mixed-status households. Health care providers can benefit from the proposed recommendations by building bridges to care to address health equity in immigrant communities. PMID- 29448886 TI - Augmenting treatment efficiency in exposure therapy for PTSD: a randomized double blind placebo-controlled trial of yohimbine HCl. AB - The alpha-2 adrenergic receptor antagonist, yohimbine, can facilitate fear extinction in animals and humans. One potential mechanism is increased noradrenergic activity and associated arousal in the presence of conditioned stimuli. Accordingly, yohimbine might augment prolonged exposure (PE) therapy for posttraumatic stress disorder (PTSD), where heightened exposure-oriented arousal is a theorized driver and empirical predictor of treatment success. A double blind placebo-controlled randomized trial (NCT 01031979) piloted yohimbine augmentation in 26 males with combat-related PTSD. Participants were given one time dose of yohimbine or placebo prior to the first imaginal exposure. Subsequently, both arms completed standard PE. The primary outcome was trauma cued heart-rate reactivity a week after the drug/exposure visit, a highly specified, objective measure sensitive to incremental change. Secondary outcomes included arousal during the drug/exposure visit and slope of distress, PTSD, and depression over the course of PE. Consistent with hypothesis, yohimbine led to higher objective and subjective arousal during the drug/exposure visit and to lower trauma-cued heart-rate reactivity one-week later. One dose of yohimbine also led to greater between-session habituation and more rapid improvement on depression, but not PTSD, over the course of care. Results of this controlled pilot indicate support for continued investigation of yohimbine-augmented exposure therapy for PTSD. PMID- 29448887 TI - Fabrication of iron oxide nanocolloids using metallosurfactant-based microemulsions: antioxidant activity, cellular, and genotoxicity toward Vitis vinifera. AB - The present work aims at the fabrication of iron oxide nanocolloids using biocompatible microemulsion and their cytotoxic, genotoxic effect on Vitis vinifera plant has been evaluated. The three iron-based metallosurfactant complexes were synthesized. Nanosuspensions (Ns) were prepared using microemulsion technique and for the purpose, the microemulsion was prepared using oleic acid, butanol, tween 80 and as synthesized iron metallosurfactant. In this technique, no additional capping agent and/or reducing agent was added. Tween 80 which is a biocompatible surfactant acted as a reducing agent as well as stabilizing for the iron oxide Ns. Characterization of Ns's was done using TEM, FESEM, EDX, XRD, AFM, and zeta potential. Mixed type of iron oxide nanoparticles i.e. magnetite (Fe3O4), and maghemite (Fe2O3) with a size range of 1-16 nm was found to be present in the nanosuspensions prepared from all the three precursors. The antioxidant activity of the Fe Ns was also confirmed using DPPH assay, with order of activity FeDDA > FeCTAC > FeHEXA. The cellular toxicity of Ns was evaluated by observing the morphological changes on V. vinifera plant (petiole) using a light microscope. Further, the interactions of iron oxide Ns with V. vinifera's DNA (plant-DNA) was assessed using circular dichroism (CD) and gel electrophoresis. For the case of FeCTAC Ns, a decrease in the intensity of bands was observed indicating fragmentation or adduct formation resulting in DNA damage. In the case of FeDDA, a modest decrease in the intensity of bands was observed. However, for FeHEXA Ns, complete neutralization of bands was confirmed implying maximum damage to the plant DNA. CD, gel electrophoresis and antioxidant activity confirmed that FeHEXA Ns were most toxic and FeDDA Ns were safest among the three as-fabricated nanosuspensions. PMID- 29448888 TI - Cross-Linked Cholecyst-Derived Extracellular Matrix for Abdominal Wall Repair. AB - Abdominal wall repair frequently utilizes either nondegradable or biodegradable meshes, which are found to stimulate undesirable biological tissue responses or which possess suboptimal degradation rate. In this study, a biologic mesh prototype made from carbodiimide cross-linked cholecyst-derived extracellular matrix (EDCxCEM) was compared with small intestinal submucosa (Surgisis(r)), cross-linked bovine pericardium (Peri-Guard(r)), and polypropylene (Prolene(r)) meshes in an in vivo rabbit model. The macroscopic appearance and stereological parameters of the meshes were evaluated. Tailoring the degradation of the EDCxCEM mesh prevents untimely degradation, while allowing cellular infiltration and mesh remodeling to take place in a slower but predictable manner. The results suggest that the cross-linked biodegradable cholecyst-derived biologic mesh results in no seroma formation, low adhesion, and moderate stretching of the mesh. In contrast to Surgisis, Peri-Guard, and Prolene meshes, the EDCxCEM mesh showed a statistically significant increase in the volume fraction (Vv) of collagen (from 34% to 52.1%) in the central fibrous tissue region at both day 28 and 56. The statistically high length density (Lv), of blood vessels for the EDCxCEM mesh at 28 days was reflected also by the higher cellular activity (high Vv of fibroblast and moderate Vv of nuclei) indicating remodeling of this region in the vicinity of a slowly degrading EDCxCEM mesh. The lack of mesh area stretching/shrinkage in the EDCxCEM mesh showed that the remodeled tissue was adequate to prevent hernia formation. The stereo-histological assays suggest that the EDCxCEM delayed degradation profile supports host wound healing processes including collagen formation, cellular infiltration, and angiogenesis. The use of cross-linked CEM for abdominal wall repair is promising. PMID- 29448889 TI - Potential of the Moringa oleifera saline extract for the treatment of dairy wastewater: application of the response surface methodology. AB - In this work, the coagulation/flocculation/sedimentation treatment of dairy wastewater samples was investigated through serial factorial designs utilizing the saline extract obtained from Moringa oleifera (Moringa) as a coagulant. The sedimentation time (ST), pH, Moringa coagulant (MC) dose and concentration of CaCl2 have been evaluated through the response surface methodology in order to obtain the ideal turbidity removal (TR) conditions. The empirical quadratic model, in conjunction with the desirability function, demonstrated that it is possible to obtain TRs of 98.35% using a coagulant dose, concentration of CaCl2 and pH of 280 mg L-1, 0.8 mol L-1 and 9, respectively. The saline extract from Moringa presented its best efficiency at an alkaline pH, which influenced the reduction of the ST to a value of 25 min. It was verified that the increase in the solubility of the proteins in the Moringa stimulated the reduction of the coagulant content in the reaction medium, and it is related to the use of calcium chloride as an extracting agent of these proteins. The MC proved to be an excellent alternative for the dairy wastewater treatment, compared to the traditional coagulants. PMID- 29448890 TI - Evaluation of hybrid neutralization/biosorption process for zinc ions removal from automotive battery effluent by dolomite and fish scales. AB - This work focused in the evaluation of Oreochromis niloticus fish scales (FS) as biosorbent material in the removal of Zn from a synthetic effluent based on automotive battery industry effluent and, further, a hybrid neutralization/biosorption process, aiming at a high-quality treated effluent, by a cooperative use of dolomite and FS. For this, a physicochemical and morphological characterization (i.e. SEM-EDX, FTIR, XRD, and TXRF) was performed, which helped to clarify a great heterogeneity of active sites (phosphate, carbonate, amide, and hydroxyl) on the biosorbent; also the inorganic constituents (apatites) leaching from the FS was identified. Biosorption results pointed out to a pH-dependent process due to changes in the functional group's anionic character (i.e. electrostatic interactions), where an initial pH = 3 favored the Zn uptake. Kinetic and equilibrium studies confirmed the heterogeneous surface and cooperative sorption, wherein experimental data were described by Generalized Elovich kinetic model and the favorable isotherm profile by Langmuir-Freundlich isotherm ([Formula: see text] = 15.38 mg g-1 and [Formula: see text]). Speciation diagram of Zn species along with the leached species demonstrated that, for the studied pH range, the biosorption was the most likely phenomena rather than precipitation. Finally, the hybrid neutralization/biosorption process showed great potential since both the Zn concentration levels and the pH reached the legislation standards (CZn = 4 mg L 1; pH = 5). Hence, based on the characterization and biosorption results, a comprehensive evaluation of the involved mechanisms in such complex system helped to verify the prospective of FS biosorbent for the Zn treatment from solution, in both individual and hybrid processes. PMID- 29448891 TI - Impact of landfill density on transport and hydraulic characteristics of recirculated leachate. AB - To achieve a uniform water distribution and to promote the stabilization of bioreactor landfills, the effects of different density on the transport and hydraulic characteristics of recirculated leachate were studied in a Li+ tracer experiment. The landfill density was related negatively to the maximum production rate of leachate, the percentage of Li+ tracer solution and the cumulative amount of Li+ that washed out in the first recirculation round. The cumulative amount of Li+ that was washed out accounted for 92.61%, 82.07% and 75.25% of the injection volume in three waste columns (1#, 2# and 3#) with landfill densities of 497.5, 726.4 and 970.1 kg m-3 at the thirtieth recirculation, respectively. The results revealed that a greater landfill density yielded a smaller amount of Li+ that was washed out per recirculation cycle and the cumulative amount of Li+ washed out, and a longer contact time between the waste and leachate. Moreover, waste columns 1#, 2# and 3# are reactors with a high dispersion and obvious retention zones, and their Morrill Dispersion Index (MDI) values were 25.00, 34.51 and 24.55, respectively. A short-flow phenomenon is obvious in the reactor with a low landfill density. Furthermore, the plug-flow effect is relatively better in the reactor with a high landfill density. To achieve a uniform distribution of recirculated leachate in the landfill, the MDI of the reactor should be reduced combined with other measures, such as pre-crushing and different recirculation schemes. PMID- 29448892 TI - Examining the role of racism in the risky alcohol use behaviors of black female college students. AB - OBJECTIVE: This study explores the impact racism has on the drinking behaviors of Black college women. Little is known about Black college women's experience of racism and the impact racism has on their psychological wellbeing and drinking behaviors. The current study fills a gap in our understanding of the role racism plays in the risky drinking behavior of Black college women. PARTICIPANTS: 469 Black college women ages 18-29 were sampled from 8 colleges and universities across the US, in 3 waves from December 2014-August 2017. RESULTS: Findings suggest that general life stress and perceived racism are significantly associated with alcohol use among Black college women. However, only increased experiences of racism increase Black college women's engagement in risky drinking. CONCLUSIONS: The findings of this study serve as an entry point for a more nuanced assessment of stressors among Black college women that may inform drinking behaviors in this population. PMID- 29448893 TI - Arsenic species in rice and rice-based products consumed by toddlers in Switzerland. AB - Inorganic arsenic (iAs) is a contaminant present in food, especially in rice and rice-based products. Toxicity of arsenic compounds (As) depends on species and oxidative state. iAs species, such as arsenite (As(III)) and arsenate (As(V)), are more bioactive and toxic than organic arsenic species, like methylarsonic acid (MMA(V)) and dimethylarsinic acid (DMA(V)) or arsenosugars and arsenobetaine. An ion chromatography-inductively coupled-plasma-mass spectroscopy method was developed to separate the four following arsenic anions: As(III), As(V), MMA(V) and DMA(V). Sample preparation was done in mild acidic conditions to ensure species preservation. The predominant arsenic species found in rice and rice-based products, except for rice drinks, was As(III), with 60-80% of the total As content, followed by DMA(V) and As(V). MMA(V) was measured only at low levels (<3%). Analyses of rice products (N = 105) intended for toddlers, including special products destined for infants and toddlers, such as dry form baby foods (N = 12) or ready-to-use form (N = 9), were done. It was found in this study that there is little or no margin of exposure. Risk assessment, using the occurrence data and indicated intake scenarios compared to reference BMDLs as established by EFSA, demonstrated toddlers with a high consumption of rice based cereals and rice drinks are at risk of high iAs exposure, for which a potential health risk cannot be excluded. PMID- 29448894 TI - Noninvasive Optical Assessment of Implanted Engineered Tissues Correlates with Cytokine Secretion. AB - Fluorescence lifetime sensing has been shown to noninvasively characterize the preimplantation health and viability of engineered tissue constructs. However, current practices to monitor postimplantation construct integration are either qualitative (visual assessment) or destructive (tissue histology). We employed label-free fluorescence lifetime spectroscopy for quantitative, noninvasive optical assessment of engineered tissue constructs that were implanted into a murine model. The portable system was designed to be suitable for intravital measurements and included a handheld probe to precisely and rapidly acquire data at multiple sites per construct. Our model tissue constructs were manufactured from primary human cells to simulate patient variability based on a standard protocol, and half of the manufactured constructs were stressed to create a range of health states. Secreted amounts of three cytokines that relate to cellular viability were measured in vitro to assess preimplantation construct health: interleukin-8 (IL-8), human beta-defensin 1 (hBD-1), and vascular endothelial growth factor (VEGF). Preimplantation cytokine secretion ranged from 1.5 to 33.5 pg/mL for IL-8, from 3.4 to 195.0 pg/mL for hBD-1, and from 0.1 to 154.3 pg/mL for VEGF. In vivo optical sensing assessed constructs at 1 and 3 weeks postimplantation. We found that at 1 week postimplantation, in vivo optical parameters correlated with in vitro preimplantation secretion levels of all three cytokines (p < 0.05). This correlation was not observed in optical measurements at 3 weeks postimplantation when histology showed that the constructs had re epithelialized, independent of preimplantation health state, supporting the lack of a correlation. These results suggest that clinical optical diagnostic tools based on label-free fluorescence lifetime sensing of endogenous tissue fluorophores could noninvasively monitor postimplantation integration of engineered tissues. PMID- 29448895 TI - The Outcome of Anticoagulation on Endovenous Laser Therapy for Superficial Venous Incompetence. AB - OBJECTIVES: The purpose of this study was to evaluate whether anticoagulation (warfarin or direct oral inhibitors) affected the success of endovenous treatment. METHODS: Patients taking anticoagulation (warfarin or direct oral inhibitors) undergoing endovenous treatment in the form of endovenous laser ablation (EVLA) were matched against controls for sex, age, leg, and vein. Data were collected prospectively between January 2012 and March 2017. The primary endpoint was failure of treatment at 6-week postoperative duplex scan. The rates of major bleeding, hematoma, endothermal heat-induced thrombosis, venous thromboembolism, or pulmonary embolism were also compared between groups. RESULTS: Two hundred eighty-four limbs underwent EVLA during the study period. Of this, 23/284 (8.1%) procedures were done in patients on anticoagulation. 21/23 (91.3%) limbs had venous occlusion at follow-up compared with 23/23 (100%) of controls ( P = .49). The patient who failed treatment in the anticoagulation group had undergone small saphenous vein (SSV) ablation. There was no difference in the complication rates between groups. DISCUSSION: This study demonstrates that anticoagulation does not affect success rates of EVLA though there was higher recanalization rate in patients undergoing SSV ablation. Anticoagulation can be continued safely in patients undergoing this procedure. PMID- 29448896 TI - Circulating Neutrophil Extracellular Traps Are Elevated in Patients With Deep Infiltrating Endometriosis. AB - Neutrophil extracellular traps (NETs) have been described to be related to the pathogenesis of inflammatory and autoimmune conditions. Endometriosis is currently considered a chronic inflammatory condition. Therefore, we performed a preliminary case-control study to compare the circulating plasma NET levels in patients with surgically confirmed endometriosis (E group, n = 82) and those of patients without surgical findings of endometriosis (C group, n = 35). Venous blood samples were obtained at the time of surgery. Circulating plasma NET levels were assessed as histone-DNA complexes (ie, nucleosomes) by a quantitative sandwich enzyme-linked immunosorbent assay. The results were expressed in arbitrary units. Circulating plasma NET levels were significantly higher in the E group compared with the C group (median [25th; 75th percentiles]): E group: 0.734 [0.484; 1.363]; C group: 0.541 [0.411; 0.653]; P = .005). The subanalysis of E group patients with deep infiltrating endometriosis (DIE group) or without DIE (non-DIE group) showed that plasma NET levels were higher in the DIE group ( P = .02). No differences were observed in NET levels among patients with and without severe pelvic pain or in patients with and without infertility, regardless of the presence of endometriotic lesions. Therefore, our study shows significantly higher NET levels in patients with endometriosis, which seem to be attributed to increased levels in the subgroup of patients with DIE, suggesting that the presence of elevated circulating plasma NET levels may reflect an inflammatory status in this gynecological condition. Further research is warranted to confirm our findings and to assess the exact role of NETs in the pathophysiological mechanisms of endometriosis. PMID- 29448897 TI - Immunomodulation by food: impact on gut immunity and immune cell function. AB - Recent studies have revealed that various food components affect the immune response. These components act on various immune cells, and their effects are mediated through the intestinal immune system and, in some cases, the intestinal microbiota. In this review, we describe the immunomodulating effects of various food components, including probiotics, prebiotics, polysaccharides, vitamins, minerals, fatty acids, peptides, amino acids and polyphenols. Some of these components enhance immune responses, leading to host defense against infection, whereas others inhibit immune responses, thus suppressing allergy and inflammation. PMID- 29448898 TI - A membrane aerated biofilm reactor for sulfide control from anaerobically treated wastewater. AB - A upflow anaerobic sludge blanket reactor was operated combined to a membrane aerated biofilm reactor for sulfate removal and for elemental sulfur reclamation. A commercial silicon tube was used as an oxygen delivery diffuser. The process achieved high rates of sulfide removal from the liquid phase (90%). The hydrogen sulfide removal was influenced by the pH value and at pH value of 7.5, 98% of the H2S was removed. The elemental sulfur was observed inside the membrane, with content in the biomass of 21%. Through the massive sequencing of the samples, the microbial community diversity and the stratification of biomass inside the silicon tube was demonstrated, confirming the presence of sulfide-oxidizing bacteria on the membrane wall. The most important genera found related to the sulfur cycle were Sulfuricurvum, Geovibrio, Flexispira and Sulforospirillum. PMID- 29448899 TI - Dietary exposure of the Belgian population to emulsifiers E481 (sodium stearoyl-2 lactylate) and E482 (calcium stearoyl-2-lactylate). AB - A dietary exposure assessment of food emulsifiers E481 (sodium stearoyl-2 lactylate) and E482 (calcium stearoyl-2-lactylate) in the Belgian population was performed. Nationally representative food consumption data from the Belgian National Food Consumption Surveys 2004 (BNFCS2004) and 2014 (BNFCS2014) were used for calculations. A conservative approach (combining individual food consumption data with the maximum permitted level (MPL) of foods (tier 2), was compared with more refined estimates (combining individual food consumption data with actual concentrations measured in food products available on the Belgian market (tier 3)). Estimated daily intakes were compared to the acceptable daily intake (ADI) of the stearoyl-2-lactylates. The results of tier 2 demonstrated that 92% of the children (3-9 years), 53% of the adolescents (10-17 years), 15% of the adults (18 64 years) and 26% of the elderly (64-98 years) had a potential intake higher than the ADI. When replacing the MPL with maximum analysed concentration levels in foods, daily intake estimates decreased dramatically. The estimated daily intake of the food emulsifiers was below the ADI for all age groups, except for a small percentage of children (1.9%) for which the intake exceeded the ADI. The main contributors to the exposure of E481 and E482 were bread, rolls and fine bakery wares. PMID- 29448900 TI - Provision of surgical care in Ethiopia: Challenges and solutions. AB - : With the lowest measured rate of surgery in the world, Ethiopia is faced with a number of challenges in providing surgical care. The aim of this study was to elucidate challenges in providing safe surgical care in Ethiopia, and solutions providers have created to overcome them. Semi-structured interviews were conducted with 10 practicing surgeons in Ethiopia. Following de-identification and immersion into field notes, topical coding was completed with an existing coding manual. Codes were adapted and expanded as necessary, and the primary data analyst confirmed reproducibility with a secondary analyst. Qualitative analysis revealed topics in access to care, in-hospital care delivery, and health policy. Patient financial constraints were identified as a challenge to accessing care. Surgeons were overwhelmed by patient volume and frustrated by lack of material resources and equipment. Numerous surgeons commented on the inadequacy of training and felt that medical education is not a government priority. They reported an insufficient number of anaesthesiologists, nurses, and support staff. Perceived inadequate financial compensation and high workload led to low morale among surgeons. Our study describes specific challenges surgeons encounter in Ethiopia and demonstrates the need for prioritisation of surgical care in the Ethiopian health agenda.

AB - The objective of the study was to determine the effect of different types of soy sauce and marinating time on the formation of heterocyclic amines (HCAs) in roasted chicken. Chicken breast samples were marinated with sweet, salty, light and dark soy sauce at 0, 3, 6 and 12 h (control treatment was the chicken without marinade). The concentrations of free amino acids, sugars and creatinine were determined before roasting while HCA concentrations were determined after roasting. All types of soy sauce significantly increased (p <= 0.05) the concentration of HCAs in roasted chicken with increasing marinating time. The highest increment of total concentration of HCAs was found in samples marinated with light soy sauce (887%) followed by dark (375%), salty (193%) and sweet (169%) at 12 h. PhIP (2-amino-1-methyl-6-phenylimidazo(4,5-b)pyridine) showed a substantial reduction in samples only momentarily marinated with sweet, salty and dark soy sauce (0 h). Free amino acids were found to be more strongly correlated with the formation of HCAs than reducing sugars or creatinine.

AB - Uteri from 50 four-toed hedgehogs ( Atelerix albiventris) with clinical signs of uterine disease were histopathologically examined. Sixteen animals (32%) were diagnosed with endometrial hyperplasia, 7 animals (14%) were diagnosed with endometrial polyp, and 27 animals (54%) were diagnosed with endometrial neoplasia. The mean ages of the animals with endometrial hyperplasia, polyp, and neoplasia were 28.7 months, 29.4 months, and 25.2 months, respectively. The neoplasms were classified into 7 endometrial mixed tumors, 12 endometrial stromal nodules, and 8 endometrial stromal sarcomas. However, the endometrial stromal nodules and endometrial stromal sarcomas often developed within or were contiguous with an endometrial polyp or mixed tumor. Interestingly, the stromal tumors and the stromal components of the endometrial polyp and mixed tumor displayed extraendometrial differentiation (eg, into adipocytes, granular cells, smooth muscle cells, and osteoid tissue). The endometrial stromal sarcomas exhibited severe cellular atypia and invaded subendometrial tissue. Immunohistochemical examinations demonstrated that the stromal cells of the hyperplastic lesions as well as the neoplastic lesions were positive for CD10, the progesterone receptor, and Wilms tumor 1. The four-toed hedgehog develops unique uterine neoplasms that are mainly composed of endometrial stromal cells and probably arise from endometrial polyps and/or mixed tumors. PMID- 29448905 TI - Restoration of sleep using a novel biomimetic protocol for adult OSA: Clinical case report. AB - Background A sleep study of a 56-year old male with excessive daytime sleepiness demonstrated an AHI of 16.4hr-1 with 13% of total sleep time in REM sleep and a mean oxygen desaturation (SpO2) of 86%. Clinical presentation On intra-oral examination, it was found that the patient had maxillary hypoplasia and bilateral torus mandibularis. A 3D cone-beam CT (CBCT) scan was taken, and 28 craniofacial parameters were measured. Surgical reduction of the mandibular tori followed by biomimetic oral appliance therapy (BOAT) was initiated. After 14 months, a post treatment CBCT scan revealed that 70% of parameters measured had improved. Therefore, another sleep study was performed with no device in the mouth. This follow-up home sleep test demonstrated that the AHI fell to 5.3hr-1hr; with 27% REM sleep, and a mean SpO2 of 93% without any device in the mouth. Conclusion These findings suggest that BOAT might be able to restore sleep in certain adult cases. PMID- 29448906 TI - Violence and Abuse in Rural Older Women's Lives: A Life Course Perspective. AB - Intimate partner violence in later life includes physical, psychological, sexual, and financial abuse. Although some researchers have investigated how women in long-term violent partnerships cope with abuse, little is known about the history, experiences, and needs of older women who leave abusive relationships. From a feminist, life course perspective, we interviewed 10 women who had left their abusive partners later in life. We used qualitative methods to analyze the data and found four major themes: (a) the women used the past to account for abuse in their relationships later in life, (b) recognizing abuse signaled to the women to fight back and exit the relationship, (c) financial abuse and exploitation affected women's mental and physical health, and (d) rebuilding was especially challenging as the women faced their future alone with financial, physical, or mental health problems. We conclude that abuse presents lasting and unique challenges for older women. PMID- 29448907 TI - Disclosure of Sexual Violence Among Girls and Young Women Aged 13 to 24 Years: Results From the Violence Against Children Surveys in Nigeria and Malawi. AB - Understanding factors that are associated with disclosure of sexual violence (SV) is important for the delivery of health services as well as developing strategies for prevention and response. The Violence Against Children Surveys were conducted in Malawi and Nigeria. We examined the prevalence of SV, help-seeking behaviors, and factors associated with disclosure among girls and young women aged 13 to 24. The self-reported prevalence of SV was similar in Nigeria (26%) and Malawi (27%). Among females who experienced SV, approximately one third (37%) in Nigeria and one half (55%) in Malawi ever disclosed their experience of SV. Females in Nigeria were significantly more likely to disclose to their parents (31.8%) than females in Malawi (9.5%). The most common reason for nondisclosure in Nigeria was not feeling a need or desire to tell anyone (34.9%) and in Malawi was embarrassment (29.3%). Very close relationships with one or both parents were significantly associated with disclosure among Nigerian females (odds ratio [OR] = 5.5, 95% confidence interval [CI] = [2.1, 14.6]) but were inversely associated with disclosure among Malawian females (OR = 0.05, 95% CI = [0.01, 0.33]). Reasons for nondisclosure of SV and factors associated with disclosure among females differ in the African nations studied. The stigma associated with shame of SV may prevent females from disclosing and thus receiving necessary support and health, social, and other services. This study demonstrates a need to reduce barriers for disclosure to improve the delivery of health, social, and other response services across African nations, as well as to develop culturally appropriate strategies for its response. PMID- 29448908 TI - The Role of Cultural Factors on Dating Aggression and Delinquency Among Latino Youth. AB - There is limited research comparatively evaluating delinquency and dating aggression among Latino youth. This analysis examines the rates and cultural correlates associated with delinquency and dating aggression among Latino youth using data from the Dating Violence Among Latino Adolescents study. The study surveyed 1,525 Latino adolescents between the ages of 12 and 18 years about past year dating aggression perpetration and delinquency. Dating aggression perpetration and delinquency rates and relative risk ratios are presented. Logistic regression analyses examined the role of cultural factors on the perpetration of dating aggression and delinquent behaviors. Results showed that cultural factors had differential influence on dating aggression versus delinquency. Specifically, victimization, acculturation, and familial support were associated with dating aggression whereas only victimization and familial support were associated with delinquency. The results provide guidance for intervention and prevention efforts with Latino youth, particularly on the need for cultural consideration and the supportive role family can play in addressing these behaviors. PMID- 29448909 TI - A Preliminary Investigation Into a Range of Implicit and Explicit Offense Supportive Cognitions in Perpetrators of Physical Intimate Partner Violence. AB - The current study assessed a wide range of offense supportive cognitions in relation to the perpetration of physical intimate partner violence (IPV). This research used both implicit and explicit measures in a U.K. sample of 19 male IPV perpetrators recruited from a community-based IPV intervention program and 20 men from the community with no history of IPV. The study also explored the ability of the implicit measures to differentiate between the two groups. The cognitions assessed included gender-role stereotype, attitudes condoning violence against a partner, attitudes condoning violence in general, hostile attitudes toward women, sense of entitlement in the relationship and over the intimate partner (control and dominance), and general sense of entitlement. Participants completed a number of established self-report measures and a series of computer-based reaction time tasks including two implicit association tests, one go/no-go association task, and four sentence judgment tasks. Significant group differences emerged across all measures both at the explicit and at the implicit level. Most implicit measures had very good discriminatory power, and the combination of all implicit measures showed excellent discriminatory power, equal to that of the explicit measures combined. These findings suggest that some IPV perpetrators hold offense supportive cognitions that may have become fairly well established and have started to operate at an automatic level. Implicit measures could be useful tools for risk assessment purposes and identification of treatment needs alongside already established measures. PMID- 29448910 TI - Assessing the Mediating Role of Social Support in Childhood Maltreatment and Psychopathology Among College Students in Northern Ireland. AB - The detrimental impact of early trauma, particularly childhood maltreatment, on mental health is well documented. Although it is understood that social support can act as a protective factor toward mental health for children who experience such adversity, few studies have addressed the experience of childhood maltreatment and the important function of social support in adulthood. The current study aimed to assess the mediating role of social support in the relationship between childhood experiences of maltreatment and mental health outcomes including anxiety, depression, posttraumatic stress disorder (PTSD), and problematic alcohol use in a sample of university students ( N = 640) from Northern Ireland. Results of binary logistic regression analyses indicated that those reporting experiences of childhood maltreatment were at increased odds of mental health outcomes of PTSD, anxiety, and depression, but not alcohol use. Those reporting greater social support were significantly less likely to report on these mental health outcomes. In addition, the indirect paths from childhood maltreatment through social support to PTSD, depression, and anxiety were all significant, suggesting that social support, particularly family support, is a significant mediator of these relationships. Such findings have important implications for the social care response to children experiencing maltreatment and future support for such children as they transition to adolescence and adulthood. PMID- 29448911 TI - Investigation of the selectivity of one type of small-molecule inhibitor for three Nav channel isoforms based on the method of computer simulation. AB - Voltage-gated sodium (Nav) channels play a pivotal role for the changes in membrane potential and belong to large membrane proteins that compose four voltage sensor domains (VSD1-4). In this study we describe the binding mode and selectivity of one of the aryl sulfonamide sodium channel inhibitors, PF 04856264, for the VSD4s in Nav1.4, Nav1.5 and Nav1.7, respectively, through molecular dynamics simulation and enhanced post-dynamics analyses. Our results show that there are three binding site regions (BSR1-3) in the combination of the ligand and receptors, of which BSR1 and BSR3 contribute to the selectivity and affinity of the ligand to the receptor. What's more, the 39th residue (Y39 in VSD4hNav1.4/ VSD4hNav1.7 and A39 in VSD4hNav1.5) and N42 in BSR1, the 84th residue (L84 in VSD4hNav1.4, T84 in VSD4hNav1.5 and M84 in VSD4hNav1.7) in BSR2 and the conserved positive charged residues in BSR3 have major contributions to the interaction between the ligand and receptor. Further analysis reveals that if the 39th residue has a benzene ring structure, the connection of BSR1 and the ligand would be much stronger through pi-stacking interaction. On the other hand, the strength and number of the hydrogen bonds formed by the ligand and the conserved arginines on S4 determine the contribution of BSR3 to the total free binding energy. We anticipate this study pave the way for the design of more effective and safe treatment for pain that selectively target Nav1.7. PMID- 29448912 TI - A variant in the SCN10A enhancer may affect human mechanical pain sensitivity. AB - Expression of Nav1.8, encoded by SCN10A, can affect pain transmission and thus mediate the human pain phenotype. In the current study, we assessed whether the variant rs6801957, located in the SCN10A enhancer region, may have the potential to affect human pain. Through dual-luciferase reporter assays in 293T cells, we found that the SCN10A enhancer A (Enh-A) increased the activity of the SCN10A promoter ( P < 0.05). Additionally, in a cohort of 309 healthy women, mutant rs6801957 A/A was found to have a significant association with decreased human experimental mechanical pain sensitivity ( P < 0.05). We then found that mutant genotype A/A suppressed the increased effect of Enh-A compared with wild-type G/G ( P < 0.05). The association between rs6801957 and human experimental mechanical pain sensitivity was further validated in a larger cohort of 1005 women ( P < 0.05). In conclusion, these results demonstrated that the variant rs6801957 and Enh-A may affect SCN10A gene expression and play an important role in human mechanical pain sensitivity. PMID- 29448915 TI - Shear Conditioning of Adipose Stem Cells for Reduced Platelet Binding to Engineered Vascular Grafts. AB - Conferring antithrombogenicity to tissue-engineered vascular grafts remains a major challenge, especially for urgent bypass grafting that excludes approaches based on expanding autologous endothelial cells (ECs) that requires weeks of cell culture. Adipose-derived stem cells (ASCs) are available from most patients in sufficient number for coronary bypass graft seeding and may be effective as allogeneic cells. We thus compared the adhesion and platelet binding of human ASCs that were shear conditioned with constant and pulsatile shear stress (SS) after seeding the cells on a biologically engineered matrix suitable for arterial grafts. A monolayer of cells was maintained up to 15 dyn/cm2 constant SS and up to 15 dyn/cm2 mean pulsatile SS for 6 days of shear flow. Platelet binding was reduced from 83% to 6% of surface area and nitric oxide production was increased 23-fold with 7.5-15 dyn/cm2 constant SS, but not pulsatile SS, relative to cells cultured statically on the matrix for 6 days. The reduction in platelet binding varied from no reduction to maximum reduction over a constant shear range of ~2 to 4 dyn/cm2, respectively. Collectively, the study supports the potential use of ASCs to seed the luminal surface of a vascular graft made from this biologically engineered matrix to confer an antithrombogenic surface during the development of an endothelium from the seeded cells or the surrounding blood and tissue. PMID- 29448916 TI - Tensioning of the radioscaphocapitate and long radio-lunate ligaments for dynamic radiocarpal instability. AB - : During 1994-2003, we treated 20 patients with post-traumatic radial-sided wrist pain and dynamic radiocarpal instability. After arthroscopy confirmed no disruption of the radioscaphocapitate ligament and an increased laxity of the ligament, we passed a strip of the radioscaphocapitate ligament through the long radio-lunate ligament. The rationale of this procedure was to increase tension of the two ligaments and to close the space of Poirier. Eighteen patients were assessed after 1-3.7 years (mean 2.5 years). Four patients were symptom-free and 11 patients were markedly improved. Fourteen patients were followed for 11-15 years; four patients were symptom-free and eight patients were markedly improved. Two reported unchanged symptoms and none was worse in the follow-up. Based on our findings, we suggest a cause of post-traumatic radial-sided wrist pain is laxity of the radiocarpal joint. We conclude that our surgical procedure increases tension in the radioscaphocapitate and long radio-lunate ligaments and decreases wrist pain at rest and during activity. LEVEL OF EVIDENCE: IV. PMID- 29448914 TI - Quantitative evaluation to efficacy and safety of therapies for psoriasis: A network meta-analysis. AB - Therapies treating psoriasis can be categorized into five classes according to their mechanism: anti-metabolites (AM), anti-interleukin-12/23 agents (anti IL12/23), anti-interleukin-17 agents (anti-IL17), anti-T-cell agent (ANT), and anti-tumor necrosis factor-alpha agent (anti-TNF-alpha). This network meta analysis (NMA) aimed to give a quantitative and systemic evaluation of safety and efficacy for the five kinds of therapies mentioned above. Odds ratios and mean differences were calculated to evaluate binary and continuous outcomes, respectively. Forest plots were conducted to show the performance of pair-wise comparison of above therapies in each outcome, and surface under the cumulative ranking curves was given to evaluate the relative ranking of above therapies in each outcome. Node splitting was conducted to evaluate the consistency between direct and indirect evidence. Direct comparisons from 65 studies (32,352 patients) were included in this NMA. Our results showed an excellent efficacy of anti-IL12/23 and anti-IL17. However, these two therapies and anti-TNF-alpha were revealed to have a high possibility to cause adverse effects (AEs) such as infections. Additionally, node splitting showed that no inconsistency appeared between the direct and indirect comparisons. Anti-IL12/23 was the most recommended therapy according to this NMA. Anti-IL17 had similar efficacy to anti IL12/23 but should be applied with caution since it has poor performance in safety outcomes. PMID- 29448913 TI - Role of medullary astroglial glutamine synthesis in tooth pulp hypersensitivity associated with frequent masseter muscle contraction. AB - Background The mechanisms underlying tooth pulp hypersensitivity associated with masseter muscle hyperalgesia remain largely underinvestigated. In the present study, we aimed to determine whether masseter muscle contraction induced by daily electrical stimulation influences the mechanical head-withdrawal threshold and genioglossus electromyography activity caused by the application of capsaicin to the upper first molar tooth pulp. We further investigated whether astroglial glutamine synthesis is involved in first molar tooth pulp hypersensitivity associated with masseter muscle contraction. Methods The first molar tooth pulp was treated with capsaicin or vehicle in masseter muscle contraction or sham rats, following which the astroglial glutamine synthetase inhibitor methionine sulfoximine or Phosphate buffered saline (PBS) was applied. Astroglial activation was assessed via immunohistochemistry. Results The mechanical head-withdrawal threshold of the ipsilateral masseter muscle was significantly decreased in masseter muscle contraction rats than in sham rats. Genioglossus electromyography activity was significantly higher in masseter muscle contraction rats than sham rats. Glial fibrillary acidic protein-immunoreactive cell density was significantly higher in masseter muscle contraction rats than in sham rats. Administration of methionine sulfoximine induced no significant changes in the density of glial fibrillary acidic protein-immunoreactive cells relative to PBS treatment. However, mechanical head-withdrawal threshold was significantly higher in masseter muscle contraction rats than PBS-treated rats after methionine sulfoximine administration. Genioglossus electromyography activity following first molar tooth pulp capsaicin treatment was significantly lower in methionine sulfoximine-treated rats than in PBS-treated rats. In the ipsilateral region, the total number of phosphorylated extracellular signal-regulated protein kinase immunoreactive cells in the medullary dorsal horn was significantly smaller upon first molar tooth pulp capsaicin application in methionine sulfoximine-treated rats than in PBS-treated rats. Conclusions Our results suggest that masseter muscle contraction induces astroglial activation, and that this activation spreads from caudal to the obex in the medullary dorsal horn, resulting in enhanced neuronal excitability associated with astroglial glutamine synthesis in medullary dorsal horn neurons receiving inputs from the tooth pulp. These findings provide significant insight into the mechanisms underlying tooth pulp hypersensitivity associated with masseter muscle contraction. PMID- 29448917 TI - A randomized controlled trial comparing ketorolac and triamcinolone injections in adults with trigger digits. AB - We assessed the efficacy of ketorolac trometamol injections compared with triamcinolone acetonide injections in trigger digits. Patients with trigger digits were randomized to receive either ketorolac or triamcinolone. They were followed up at 3, 6, 12 and 24 weeks, and monitored for resolution of triggering, pain and total active motion. One hundred and twenty-one patients with single trigger digits were recruited (59 ketorolac, 62 triamcinolone). At 6 weeks, 54% of patients in the triamcinolone group had complete resolution of trigger, whereas no patients in the ketorolac group had resolution. At 12 weeks, 58% of patients in the triamcinolone group had complete resolution of trigger compared with 6.7% in the ketorolac group. At 24 weeks, both groups had comparable rates of resolution at 26% and 25%, respectively. Patients in the triamcinolone group had significantly better resolution of pain at 3, 6 and 12 weeks. But at 24 weeks, there was no significant difference in pain between both groups. Significantly less flexion deformity was reported at 3 weeks and 6 weeks in the triamcinolone group. In the short term, ketorolac was less effective in relieving symptoms of trigger digit than triamcinolone. Level of evidence: I. PMID- 29448918 TI - Improving psychotherapy effectiveness by addressing the problem of premature termination: Introduction to a special section. AB - Premature termination appears to be a consistent problem in psychotherapy, showing up across client, treatment, and therapist types. As psychotherapy researchers and practitioners, it is important that we gain a better understanding of this negative psychotherapy event and identify methods for reducing its occurrence. This article introduces a special section on premature termination in psychotherapy. In addition to briefly introducing the articles contained in the special section, this article offers suggestions for future research on the topic of premature termination. PMID- 29448919 TI - Jasmonic acid facilitates flower opening and floral organ development through the upregulated expression of SlMYB21 transcription factor in tomato. AB - Plants coordinate the timing of flower opening with pollen and gynoecium maturation to achieve successful pollination. However, little is known about how the coordination is executed. We found that flower bud development was paused immediately before flower opening in a jasmonic acid (JA)-insensitive tomato mutant, jai1-1. Phytohormone measurement and RNA analysis in flower buds revealed that newly synthesised JA peaked at two days before flower opening and the expression of a transcription factor gene SlMYB21 delayed in jai1-1. Buds of transgenic tomato plants expressing an artificial repressor, AtMYB24-SRDX, which was expected to impede the function of SlMYB21, aborted flower opening and resembled those of jai1-1. Furthermore, the AtMYB24-SRDX plants produced abnormal pollen grains deficient in germination and pistils that did not support pollen tube elongation. We concluded that JA facilitates the expression of SlMYB21, which coordinates flower opening, pollen maturation, and gynoecium function in tomato. PMID- 29448920 TI - The T790M resistance mutation in EGFR is only found in cfDNA from erlotinib treated NSCLC patients that harbored an activating EGFR mutation before treatment. AB - BACKGROUND: Lung cancer patients with an activating mutation in the EGFR (epidermal growth factor receptor) can develop resistance to erlotinib treatment, which is often mediated by the T790M resistance mutation in EGFR. The difficulties in obtaining biopsies at progression make it challenging to investigate the appearance of the T790M mutation at progression in large patient cohorts. We have used cell free DNA (cfDNA) from patients treated with erlotinib to investigate if the development of a T790M mutation coincides with the presence of an activating EGFR mutation in the pre-treatment blood sample. METHODS: A cohort of 227 NSCLC (non-small cell lung cancer) adenocarcinoma patients was treated with erlotinib irrespective of EGFR-mutational status. Blood samples were drawn immediately before erlotinib treatment was initiated and again at progression. The cobas(r) EGFR Mutation Test v2 designed for cfDNA was used to identify 42 EGFR mutations. RESULTS: Of the 227 NSCLC patients, blood samples were available from 144 patients both before erlotinib treatment and at progression (within 1 month before or after clinical progression). One hundred and twenty-eight of the 144 were wild-type EGFR before treatment, and we demonstrate that the T790M mutation was not present at progression in any of these. In contrast, in the 16 patients with an activating EGFR mutation in the pre-treatment blood sample six patients (38%) were identified with a T790M mutation in the progression blood sample. CONCLUSION: The T790M resistance mutation is only found in the cfDNA of erlotinib-treated NSCLC patients if they have an activating EGFR mutation before treatment. PMID- 29448921 TI - Evaluation of risk factors for perforated peptic ulcer. AB - BACKGROUND: The aim of this study was to evaluate the prediction factors for perforated peptic ulcer (PPU). METHODS: At St. Luke's International Hospital in Tokyo, Japan, a case control study was performed between August 2004 and March 2016. All patients diagnosed with PPU were included. As control subjects, patients with age, sex and date of CT scan corresponding to those of the PPU subjects were included in the study at a proportion of 2 controls for every PPU subject. All data such as past medical histories, physical findings, and laboratory data were collected through chart reviews. Univariate analyses and multivariate analyses with logistic regression were conducted, and receiver operating characteristic curves (ROCs) were calculated to show validity. Sensitivity analyses were performed to confirm results using a stepwise method and conditional logistic regression. RESULTS: A total of 408 patients were included in this study; 136 were a group of patients with PPU, and 272 were a control group. Univariate analysis showed statistical significance in many categories. Four different models of multivariate analyses were conducted, and significant differences were found for muscular defense and a history of peptic ulcer disease (PUD) in all models. The conditional forced-entry analysis of muscular defense showed an odds ratio (OR) of 23.8 (95% confidence interval [CI]: 5.70-100.0), and the analysis of PUD history showed an OR of 6.40 (95% CI: 1.13 36.2). The sensitivity analysis showed consistent results, with an OR of 23.8 366.2 for muscular defense and an OR of 3.67-7.81 for PUD history. The area under the curve (AUC) of all models was high enough to confirm the results. However, anticoagulants, known risk factors for PUD, did not increase the risk for PPU in our study. The conditional forced-entry analysis of anticoagulant use showed an OR of 0.85 (95% CI: 0.03-22.3). CONCLUSIONS: The evaluation of prediction factors and development of a prediction rule for PPU may help our decision making in performing a CT scan for patients with acute abdominal pain. PMID- 29448922 TI - A randomised control crossover trial of a theory based intervention to improve sun-safe and healthy behaviours in construction workers: study protocol. AB - BACKGROUND: Exposure to sunlight can have both positive and negative health impacts. Excessive exposure to ultra-violet (UV) radiation from the sun can cause skin cancer, however insufficient exposure to sunlight has a detrimental effect on production of Vitamin D. In the construction industry there are onsite proactive behaviours for safety, but sun-safety remains a low priority. There is limited research on understanding the barriers to adopting sun-safe behaviours and the association this may have with Vitamin D production. This paper reports a protocol for an intervention study, using text messaging in combination with a supportive smartphone App. The intervention aims to both reduce UV exposure during months with higher UV levels and promote appropriate dietary changes to boost Vitamin D levels during months with low UV levels. METHOD/DESIGN: Approximately 60 construction workers will be recruited across the United Kingdom. A randomised control crossover trial (RCCT) will be used to test the intervention, with randomisation at site level - i.e. participants will receive both the control (no text messages or supportive App support) and intervention (daily text messages and supportive App). Using the Theory of Planned Behaviour (TPB) the intervention focuses on supporting sun-safety and healthy dietary decisions in relation to Vitamin D intake. The intervention emphasises cultivating the perception of normative support in the workplace, increasing awareness of control and self-efficacy in taking sun-protective behaviours, making healthier eating choices to boost Vitamin D, and tackling stigmas attached to image and group norms. Each study epoch will last 21 days with intervention text messages delivered on workdays only. The supportive App will provide supplementary information about sun protective behaviours and healthy dietary choices. The primary outcome measure is 25-hydroxy-Vitamin D [25(OH)D] level (obtained using blood spot sampling), which will be taken pre and post control and intervention periods. Secondary outcome measures are two-fold, (1) using the TPB to detect changes in behaviour, and (2) quantifying UV exposure during the UK peak radiation season (April-September) using body-mounted UV sensors. DISCUSSION: This study will provide important information about the effectiveness of a technology-based intervention to promote sun-safety and healthy behaviours in outdoor construction workers. TRIAL REGISTRATION: ISRCTN15888934 retrospectively registered 15.01.2018. PMID- 29448923 TI - Data-driven predictions and novel hypotheses about zoonotic tick vectors from the genus Ixodes. AB - BACKGROUND: With the resurgence of tick-borne diseases such as Lyme disease and the emergence of new tick-borne pathogens such as Powassan virus, understanding what distinguishes vectors from non-vectors, and predicting undiscovered tick vectors is a crucial step towards mitigating disease risk in humans. We aimed to identify intrinsic traits that predict which Ixodes tick species are confirmed or strongly suspected to be vectors of zoonotic pathogens. METHODS: We focused on the well-studied tick genus Ixodes from which many species are known to transmit zoonotic diseases to humans. We apply generalized boosted regression to interrogate over 90 features for over 240 species of Ixodes ticks to learn what intrinsic features distinguish zoonotic vectors from non-vector species. In addition to better understanding the biological underpinnings of tick vectorial capacity, the model generates a per species probability of being a zoonotic vector on the basis of intrinsic biological similarity with known Ixodes vector species. RESULTS: Our model predicted vector status with over 91% accuracy, and identified 14 Ixodes species with high probabilities (80%) of transmitting infections from animal hosts to humans on the basis of their traits. Distinguishing characteristics of zoonotic tick vectors of Ixodes tick species include several anatomical structures that influence host seeking behavior and blood-feeding efficiency from a greater diversity of host species compared to non vectors. CONCLUSIONS: Overall, these results suggest that zoonotic tick vectors are most likely to be those species where adult females hold a fecundity advantage by producing more eggs per clutch, which develop into larvae that feed on a greater diversity of host species compared to non-vector species. These larvae develop into nymphs whose anatomy are well suited for more efficient and longer feeding times on soft-bodied hosts compared to non-vectors, leading to larger adult females with greater fecundity. In addition to identifying novel, testable hypotheses about intrinsic features driving vectorial capacity across Ixodes tick species, our model identifies particular Ixodes species with the highest probability of carrying zoonotic diseases, offering specific targets for increased zoonotic investigation and surveillance. PMID- 29448925 TI - Insecticide resistance evolution with mixtures and sequences: a model-based explanation. AB - BACKGROUND: Insecticide resistance threatens effective vector control, especially for mosquitoes and malaria. To manage resistance, recommended insecticide use strategies include mixtures, sequences and rotations. New insecticides are being developed and there is an opportunity to develop use strategies that limit the evolution of further resistance in the short term. A 2013 review of modelling and empirical studies of resistance points to the advantages of mixtures. However, there is limited recent, accessible modelling work addressing the evolution of resistance under different operational strategies. There is an opportunity to improve the level of mechanistic understanding within the operational community of how insecticide resistance can be expected to evolve in response to different strategies. This paper provides a concise, accessible description of a flexible model of the evolution of insecticide resistance. The model is used to develop a mechanistic picture of the evolution of insecticide resistance and how it is likely to respond to potential insecticide use strategies. The aim is to reach an audience unlikely to read a more detailed modelling paper. The model itself, as described here, represents two independent genes coding for resistance to two insecticides. This allows the representation of the use of insecticides in isolation, sequence and mixtures. RESULTS: The model is used to demonstrate the evolution of resistance under different scenarios and how this fits with intuitive reasoning about selection pressure. Using an insecticide in a mixture, relative to alone, always prompts slower evolution of resistance to that insecticide. However, when resistance to both insecticides is considered, resistance thresholds may be reached later for a sequence relative to a mixture. Increasing the ability of insecticides to kill susceptible mosquitoes (effectiveness), has the most influence on favouring a mixture over a sequence because one highly effective insecticide provides more protection to another in a mixture. CONCLUSIONS: The model offers an accessible description of the process of insecticide resistance evolution and how it is likely to respond to insecticide use. A simple online user-interface allowing further exploration is also provided. These tools can contribute to an improved discussion about operational decisions in insecticide resistance management. PMID- 29448924 TI - H2O2 mediates ALA-induced glutathione and ascorbate accumulation in the perception and resistance to oxidative stress in Solanum lycopersicum at low temperatures. AB - BACKGROUND: Low temperature is a crucial factor influencing plant growth and development. The chlorophyll precursor, 5-aminolevulinic acid (ALA) is widely used to improve plant cold tolerance. However, the interaction between H2O2 and cellular redox signaling involved in ALA-induced resistance to low temperature stress in plants remains largely unknown. Here, the roles of ALA in perceiving and regulating low temperature-induced oxidative stress in tomato plants, together with the roles of H2O2 and cellular redox states, were characterized. RESULTS: Low concentrations (10-25 mg.L- 1) of ALA enhanced low temperature induced oxidative stress tolerance of tomato seedlings. The most effective concentration was 25 mg.L- 1, which markedly increased the ratio of reduced glutathione and ascorbate (GSH and AsA), and enhanced the activities of superoxide dismutase, catalase, ascorbate peroxidase, dehydroascorbate reductase, and glutathione reductase. Furthermore, gene expression of respiratory burst oxidase homolog1 and H2O2 content were upregulated with ALA treatment under normal conditions. Treatment with exogenous H2O2, GSH, and AsA also induced plant tolerance to oxidative stress at low temperatures, while inhibition of GSH and AsA syntheses significantly decreased H2O2-induced oxidative stress tolerance. Meanwhile, scavenging or inhibition of H2O2 production weakened, but did not eliminate, GSH- or AsA- induced tomato plant tolerance to oxidative stress at low temperatures. CONCLUSIONS: Appropriate concentrations of ALA alleviated the low temperature-induced oxidative stress in tomato plants via an antioxidant system. The most effective concentration was 25 mg.L- 1. The results showed that H2O2 induced by exogenous ALA under normal conditions is crucial and may be the initial step for perception and signaling transmission, which then improves the ratio of GSH and AsA. GSH and AsA may then interact with H2O2 signaling, resulting in enhanced antioxidant capacity in tomato plants at low temperatures. PMID- 29448926 TI - Histologic chorioamnionitis in preterm infants: correlation with brain magnetic resonance imaging at term equivalent age. AB - BACKGROUND: To explore the associations between histologic chorioamnionitis with brain injury, maturation and size on magnetic resonance imaging (MRI) of preterm infants at term equivalent age. METHODS: Preterm infants (23-36 weeks' gestational age) were recruited into two longitudinal cohort studies. Presence or absence of chorioamnionitis was obtained from placental histology and clinical data were recorded. MRI at term-equivalent age was assessed for brain injury (intraventricular haemorrhage, cysts, signal abnormalities), maturation (degree of myelination, gyral maturation) and size of cerebral structures (metrics and brain segmentation). Histologic chorioamnionitis was assessed as a predictor of MRI variables using linear and logistic regression, with adjustment for confounding perinatal variables. RESULTS: Two hundred and twelve infants were included in this study, 47 (22%) of whom had histologic chorioamnionitis. Histologic chorioamnionitis was associated with higher odds of intraventricular haemorrhage (odds ratio [OR] (95% confidence interval [CI]) = 7.4 (2.4, 23.1)), less mature gyral maturation (OR (95% CI) = 2.0 (1.0, 3.8)) and larger brain volume (mean difference in cubic centimeter (95% CI) of 14.1 (1.9, 26.2)); but all relationships disappeared following adjustment for perinatal variables. CONCLUSION: Histologic chorioamnionitis was not independently associated with IVH, less mature gyral maturation or brain volume at term-equivalent age in preterm infants. PMID- 29448927 TI - Epidemiological characteristics of malaria from control to elimination in Hubei Province, China, 2005-2016. AB - BACKGROUND: Hubei Province, China, has been operating a malaria elimination programme. This study aimed at investigating the epidemiologic characteristics of malaria in Hubei Province (2005-2016) to plan resource allocation for malaria elimination. METHODS: Data on all malaria cases from 2005 to 2016 in all counties of Hubei Province were extracted from a web-based reporting system. The numbers of indigenous and imported cases during the disease control (2005-2010) and elimination (2011-2016) stages, as well as their spatiotemporal distribution, were compared. RESULTS: A total of 8109 malaria cases were reported from 2005 to 2016 (7270 and 839 cases during the control and elimination stages, respectively). Between 2005 and 2010, indigenous malaria cases comprised the majority of total cases (7114/7270; 97.9%), and Plasmodium vivax malaria cases accounted for most malaria cases (5572/7270; 76.6%). No indigenous malaria cases have been reported in Hubei Province since 2013. Imported malaria cases showed a gradually increasing trend from 2011 to 2016, Plasmodium falciparum was the predominant species in these cases, and the number of counties with imported cases increased from 4 in 2005 to 47 in 2016. During the control and elimination stages, the most likely spatial clusters for indigenous cases included 13 and 11 counties, respectively. However, the cluster of indigenous malaria cases has not been identified since September 2011. For imported cases, the most likely cluster and three secondary clusters during both stages were identified. CONCLUSIONS: Hubei Province has made significant achievements in controlling and eliminating malaria; however, the region now faces some challenges associated with the increasing number and distribution of imported malaria cases. Priorities for malaria elimination should include better management of imported malaria cases, prevention of secondary malaria transmission, and ensuring the sustainability of malaria surveillance. PMID- 29448928 TI - Prevalence of adolescent physical activity-related injuries in sports, leisure time, and school: the National Physical Activity Behaviour Study for children and Adolescents. AB - BACKGROUND: The purpose of this study was to investigate the prevalence of adolescent physical activity-related injuries in sports club activities, leisure time physical activity and school-based physical activity. The secondary aim was to investigate the differences in the prevalence of physical activity -related injuries between years 2014 and 2016. In addition, we set out to study the associations between age, sex and the frequency of physical activity and injury prevalence. METHODS: This cross-sectional study is based on the National Physical Activity Behaviour Study for Children and Adolescents (LIITU in Finnish) conducted in years 2014 and 2016. The subjects completed an online questionnaire in the classroom during school hours. A total of 8406 subjects participated in the current study. Out of these, 49% were boys and 51% were girls. The proportions of 11-, 13-, and 15-year-olds were 35%, 34% and 31%, respectively. RESULTS: In the combined data for 2014 and 2016, injury prevalence was higher in sports club activities (46%, 95% CI 44.8-47.8) than in leisure time PA (30%, 95% CI, 28.5-30.5) or school-based PA (18%, 95% CI, 17.4-19.1). In leisure time PA, the injury prevalence was higher than in school-based PA. In all the three settings, injury prevalence was higher in 2016 than in 2014. Frequency of PA was associated with a higher risk for PA-related injuries in sports clubs and leisure time. CONCLUSIONS: With half of the subjects reporting at least one PA-related injury during the past year, results indicate that adolescent PA-related injuries are a large-scale problem. There is a worrisome rise in injury prevalence in recent years. From a public health standpoint, there is an urgent need to invest in injury prevention to reverse this trend. PMID- 29448929 TI - Cost-effectiveness analysis of a school-based dental caries prevention program using fluoridated milk in Bangkok, Thailand. AB - BACKGROUND: This study modelled the cost-effectiveness, from a societal perspective, of a program that used fluoridated milk to prevent dental caries in children who were 6 years old at the beginning of the program, versus non intervention, after 6 years. METHODS: After 6 years, children in the milk fluoridation program had a significant (34%) reduction in dental caries experience compared to those in the comparison community (i.e., received school milk without added fluoride) (DMFS: 1.06 vs. 1.60). RESULTS: This improvement was achieved with an investment of Thailand Baht (THB) 5,345,048 over 6 years (or THB 11.88 per child, per year) (1 US$ = THB(2011) 30.0). When comparing the costs of the operation of the program and dental treatment in the test community with those of the comparison community, the program resulted in a net societal savings of THB 8,177,179 (range 18,597,122 to THB 7,920,711) after 6 years. This investment would result in 40,500 DMFS avoided in a community with a childhood population of 75,000 [DMFS avoided: 75,000 x (- 0.54)]. CONCLUSIONS: While the analysis has inherent limitations due to its dependence on a range of assumptions, the results suggest that, from a societal perspective, when compared with the non-intervention group, the Bangkok Metropolitan Administration intervention appeared to be a more cost-efficient option than current standard oral health care. PMID- 29448930 TI - A prediction study of warfarin individual stable dose after mechanical heart valve replacement: adaptive neural-fuzzy inference system prediction. AB - BACKGROUND: It's difficult but urgent to achieve the individualized rational medication of the warfarin, we aim to predict the individualized warfarin stable dose though the artificial intelligent Adaptive neural-fuzzy inference system (ANFIS). METHODS: Our retrospective analysis based on a clinical database, involving 21,863 patients from 15 Chinese provinces who receive oral warfarin after the heart valve replacement. They were allocated into four groups: the external validation group (A group), the internal validation group (B group), training group (C group) and stratified training group (D group). We used a univariate analysis of general linear models(GLM-univariate) to select the input variables and construct two prediction models by the ANFIS with the training and stratified training group, and then verify models with two validation groups by the mean squared error(MSE), mean absolute error(MAE) and the ideal predicted percentage. RESULTS: A total of 13,639 eligible patients were selected, including 1639 in A group, 3000 in B group, 9000 in C group, and 3192 in D group. Nine input variables were selected out and two five-layered ANFIS models were built. ANFIS model achieved the highest total ideal predicted percentage 63.7%. In the dose subgroups, all the models performed best in the intermediate-dose group with the ideal predicted percentage 82.4~ 86.4%, and the use of the stratified training group slightly increased the prediction accuracy in low-dose group by 8.8 and 5.2%, respectively. CONCLUSION: As a preliminary attempt, ANFIS model predicted the warfarin stable dose properly after heart valve surgery among Chinese, and also proved that Chinese need lower anticoagulation intensity INR (1.5-2.5) to warfarin by reference to the recommended INR (2.5-3.5) in the developed countries. PMID- 29448931 TI - Effects of different extracts of curcumin on TPC1 papillary thyroid cancer cell line. AB - BACKGROUND: The thyroid gland is one of the largest endocrine glands in the body. The vast majority of TCs (> 90%) originate from follicular cells and are defined as differentiated thyroid cancers (DTC) and the two histological subtypes are the papillary TC with its variants and the follicular TC. Curcumin possesses a wide variety of biological functions, and thanks to its properties, it has gained considerable attention due to its profound medicinal values (Prasad, Gupta, Tyagi, and Aggarwal, Biotechnol Adv 32:1053-1064, 2014). We have undertaken the present work in order to define the possible role of curcumin in modulating the genetic expression of cell markers and to understand the effectiveness of this nutraceutical in modulating the regression of cancer phenotype. METHODS: As a template we used the TPC-1 cells treated with the different extracts of turmeric, and examined the levels of expression of different markers (proliferative, inflammatory, antioxidant, apoptotic). RESULTS: Treatment with the three different curcumin extracts displays anti-inflammatory, antioxidant properties and it is able to influence cell cycle with slightly different effects upon the extracts. Furthermore curcumin is able to influence cell metabolic activity vitality. CONCLUSIONS: In conclusion curcumin has the potential to be developed as a safe therapeutic but further studies are needed to verify its antitumor ability in vivo. PMID- 29448932 TI - Interference competition as a key determinant for spatial distribution of mangrove crabs. AB - BACKGROUND: The spatial distribution of mangrove crabs has been commonly associated with tree zonation and abiotic factors such as ground temperature and soil granulometry. Conversely, no studies were designed to investigate the role of competition for resources and predation in shaping crab distribution in mangroves, despite these biotic factors are recognised as key determinants for spatial patterns observed in the communities colonising rocky and sandy intertidal habitats.We studied floral and faunal assemblages in two zones of a Sri Lankan mangrove, a man-made upper intertidal level and a natural eulittoral, mid-shore one. Leaf choice experiments were designed to study both feeding rate and intra and inter-specific interactions for food of sesarmid crabs in the two habitats in order to better understand crab spatial distribution. RESULTS: The two intertidal belts differed in terms of floral composition and crab species abundance. The eulittoral zone was strongly dominated by Neosarmatium smithi, while within the elevated littoral fringe four sesarmids (N. smithi, N. asiaticum, N. malabaricum and Muradium tetragonum) were more evenly distributed. At both levels, all sesarmids showed to collect significantly more Bruguiera spp. and Rhizophora apiculata leaves than Excoecaria agallocha ones. There was no temporal segregation in feeding activity among the four species, resulting in a high interference competition for leaves. Regardless of the habitat, N. smithi was always successful in winning inter-specific fights. CONCLUSIONS: Our results showed that the elevated littoral fringe was more crowded with crabs, but was less favourable in terms of food availability and environmental conditions. The dominance of N. smithi in gathering mangrove leaves suggests that this species may segregate the other sesarmids into less favourable habitats. The present data strongly suggest for the first time that interference competition for food can contribute to shape mangrove crab spatial distribution. PMID- 29448933 TI - The curious case of vacuolar ATPase: regulation of signaling pathways. AB - The Vacuolar ATPase (V-ATPase) is a proton pump responsible for controlling the intracellular and extracellular pH of cells. The structure of V-ATPase has been highly conserved among all eukaryotic cells and is involved in diverse functions across species. V-ATPase is best known for its acidification of endosomes and lysosomes and is also important for luminal acidification of specialized cells. Several reports have suggested the involvement of V-ATPase in maintaining an alkaline intracellular and acidic extracellular pH thereby aiding in proliferation and metastasis of cancer cells respectively. Increased expression of V-ATPase and relocation to the plasma membrane aids in cancer modulates key tumorigenic cell processes like autophagy, Warburg effect, immunomoduation, drug resistance and most importantly cancer cell signaling. In this review, we discuss the direct role of V-ATPase in acidification and indirect regulation of signaling pathways, particularly Notch Signaling. PMID- 29448934 TI - From theoretical concepts to policies and applied programmes: the landscape of integration of oral health in primary care. AB - BACKGROUND: Despite its importance, the integration of oral health into primary care is still an emerging practice in the field of health care services. This scoping review aims to map the literature and provide a summary on the conceptual frameworks, policies and programs related to this concept. METHODS: Using the Levac et al. six-stage framework, we performed a systematic search of electronic databases, organizational websites and grey literature from 1978 to April 2016. All relevant original publications with a focus on the integration of oral health into primary care were retrieved. Content analyses were performed to synthesize the results. RESULTS: From a total of 1619 citations, 67 publications were included in the review. Two conceptual frameworks were identified. Policies regarding oral heath integration into primary care were mostly oriented toward common risk factors approach and care coordination processes. In general, oral health integrated care programs were designed in the public health sector and based on partnerships with various private and public health organizations, governmental bodies and academic institutions. These programmes used various strategies to empower oral health integrated care, including building interdisciplinary networks, training non-dental care providers, oral health champion modelling, enabling care linkages and care coordinated process, as well as the use of e-health technologies. The majority of studies on the programs outcomes were descriptive in nature without reporting long-term outcomes. CONCLUSIONS: This scoping review provided a comprehensive overview on the concept of integration of oral health in primary care. The findings identified major gaps in reported programs outcomes mainly because of the lack of related research. However, the results could be considered as a first step in the development of health care policies that support collaborative practices and patient-centred care in the field of primary care sector. PMID- 29448935 TI - Germline mutations in the spindle assembly checkpoint genes BUB1 and BUB3 are infrequent in familial colorectal cancer and polyposis. AB - Germline mutations in BUB1 and BUB3 have been reported to increase the risk of developing colorectal cancer (CRC) at young age, in presence of variegated aneuploidy and reminiscent dysmorphic traits of mosaic variegated aneuploidy syndrome. We performed a mutational analysis of BUB1 and BUB3 in 456 uncharacterized mismatch repair-proficient hereditary non-polyposis CRC families and 88 polyposis cases. Four novel or rare germline variants, one splice-site and three missense, were identified in four families. Neither variegated aneuploidy nor dysmorphic traits were observed in carriers. Evident functional effects in the heterozygous form were observed for c.1965-1G>A, but not for c.2296G>A (p.E766K), in spite of the positive co-segregation in the family. BUB1 c.2473C>T (p.P825S) and BUB3 c.77C>T (p.T26I) remained as variants of uncertain significance. As of today, the rarity of functionally relevant mutations identified in familial and/or early onset series does not support the inclusion of BUB1 and BUB3 testing in routine genetic diagnostics of familial CRC. PMID- 29448936 TI - Chitinase-3-like 1 is a biomarker of acute kidney injury and mortality in paediatric severe malaria. AB - BACKGROUND: Chitinase-3-like 1 (CHI3L1) is a glycoprotein elevated in paediatric severe malaria, and an emerging urinary biomarker of acute kidney injury (AKI). Based on the hypothesis that elevated CHI3L1 levels in malaria are associated with disease severity, the relationship between plasma CHI3L1 levels, AKI and mortality was investigated in Ugandan children enrolled in a clinical trial evaluating inhaled nitric oxide (iNO) as an adjunctive therapy for severe malaria. METHODS: Plasma CHI3L1 levels were measured daily for 4 days in children admitted to hospital with severe malaria and at day 14 follow up. AKI was defined using the Kidney Disease: Improving Global Outcomes consensus criteria. This is a secondary analysis of a randomized double-blind placebo-controlled trial of iNO versus placebo as an adjunctive therapy for severe malaria. Inclusion criteria were: age 1-10 years, and selected criteria for severe malaria. Exclusion criteria included suspected bacterial meningitis, known chronic illness including renal disease, haemoglobinopathy, or severe malnutrition. iNO was administered by non-rebreather mask for up to 72 h at 80 ppm. RESULTS: CHI3L1 was elevated in patients with AKI and remained higher over hospitalization (p < 0.0001). Admission CHI3L1 levels were elevated in children who died. By multivariable analysis logCHI3L1 levels were associated with increased risk of in-hospital death (relative risk, 95% CI 4.10, 1.32-12.75, p = 0.015) and all-cause 6 month mortality (3.21, 1.47-6.98, p = 0.003) following correction for iNO and AKI. Treatment with iNO was associated with delayed CHI3L1 recovery with a daily decline of 34% in the placebo group versus 29% in the iNO group (p = 0.012). CHI3L1 levels correlated with markers of inflammation (CRP, sTREM-1, CXCL10), endothelial activation (Ang-2, sICAM-1) and intravascular haemolysis (LDH, haem, haemopexin). CONCLUSIONS: CHI3L1 is a novel biomarker of malaria-associated AKI and an independent risk factor for mortality that is associated with well established pathways of severe malaria pathogenesis including inflammation, endothelial activation, and haemolysis.

AB - Intratumor heterogeneity of tumor clones and an immunosuppressive microenvironment in cancer ecosystems contribute to inherent difficulties for tumor treatment. Recently, chimeric antigen receptor (CAR) T-cell therapy has been successfully applied in the treatment of B-cell malignancies, underscoring its great potential in antitumor therapy. However, functional challenges of CAR-T cell therapy, especially in solid tumors, remain. Here, we describe cancer immunity phenotypes from a clonal-stromal-immune perspective and elucidate mechanisms of T-cell exhaustion that contribute to tumor immune evasion. Then we assess the functional challenges of CAR-T cell therapy, including cell trafficking and infiltration, targeted-recognition and killing of tumor cells, T cell proliferation and persistence, immunosuppressive microenvironment and self control regulation. Finally, we delineate tumor precision informatics and advancements in engineered CAR-T cells to counteract inherent challenges of the CAR-T cell therapy, either alone or in combination with traditional therapeutics, and highlight the therapeutic potential of this approach in future tumor precision treatment. PMID- 29448938 TI - Comparative genomic analysis of ten clinical Streptococcus pneumoniae collected from a Malaysian hospital reveal 31 new unique drug-resistant SNPs using whole genome sequencing. AB - BACKGROUND: Streptococcus pneumoniae or pneumococcus is a leading cause of morbidity and mortality worldwide, specifically in relation to community-acquired pneumonia. Due to the overuse of antibiotics, S. pneumoniae has developed a high degree of resistance to a wide range of antibacterial drugs. METHODS: In this study, whole genome sequencing (WGS) was performed for 10 clinical strains of S. pneumoniae with different levels of sensitivity to standard antibiotics. The main objective was to investigate genetic changes associated with antibiotic resistance in S. pneumoniae. RESULTS: Our results showed that resistant isolates contain a higher number of non-synonymous single nucleotide polymorphisms (SNPs) as compared to susceptible isolates. We were able to identify SNPs that alter a single amino acid in many genes involved in virulence and capsular polysaccharide synthesis. In addition, 90 SNPs were only presented in the resistant isolates, and 31 SNPs were unique and had not been previously reported, suggesting that these unique SNPs could play a key role in altering the level of resistance to different antibiotics. CONCLUSION: Whole genome sequencing is a powerful tool for comparing the full genome of multiple isolates, especially those closely related, and for analysing the variations found within antibiotic resistance genes that lead to differences in antibiotic sensitivity. We were able to identify specific mutations within virulence genes related to resistant isolates. These findings could provide insights into understanding the role of single nucleotide mutants in conferring drug resistance. PMID- 29448939 TI - EXPOsOMICS: final policy workshop and stakeholder consultation. AB - The final meeting of the EXPOsOMICS project "Final Policy Workshop and Stakeholder Consultation" took place 28-29 March 2017 to present the main results of the project and discuss their implications both for future research and for regulatory and policy activities. This paper summarizes presentations and discussions at the meeting related with the main results and advances in exposome research achieved through the EXPOsOMICS project; on other parallel research initiatives on the study of the exposome in Europe and in the United States and their complementarity to EXPOsOMICS; lessons learned from these early studies on the exposome and how they may shape the future of research on environmental exposure assessment; and finally the broader implications of exposome research for risk assessment and policy development on environmental exposures. The main results of EXPOsOMICS in relation to studies of the external exposome and internal exposome in relation to both air pollution and water contaminants were presented as well as new technologies for environmental health research (adductomics) and advances in statistical methods. Although exposome research strengthens the scientific basis for policy development, there is a need in terms of showing added value for public health to: improve communication of research results to non-scientific audiences; target research to the broader landscape of societal challenges; and draw applicable conclusions. Priorities for future work include the development and standardization of methodologies and technologies for assessing the external and internal exposome, improved data sharing and integration, and the demonstration of the added value of exposome science over conventional approaches in answering priority policy questions. PMID- 29448940 TI - Comparative analysis of alfalfa (Medicago sativa L.) leaf transcriptomes reveals genotype-specific salt tolerance mechanisms. AB - BACKGROUND: Soil salinity is an important factor affecting growth, development, and productivity of almost all land plants, including the forage crop alfalfa (Medicago sativa). However, little is known about how alfalfa responds and adapts to salt stress, particularly among different salt-tolerant cultivars. RESULTS: Among seven alfalfa cultivars, we found that Zhongmu-1 (ZM) is relatively salt tolerant and Xingjiang Daye (XJ) is salt-sensitive. Compared to XJ, ZM showed slower growth under low-salt conditions, but exhibited stronger tolerance to salt stress. RNA-seq analysis revealed 2237 and 1125 differentially expressed genes (DEGs) between ZM and XJ in the presence and absence of salt stress, among which many genes are involved in stress-related pathways. After salt treatment, compared with the controls, the number of DEGs in XJ (19373) was about four times of that in ZM (4833). We also detected specific differential gene expression patterns: In response to salt stress, compared with XJ, ZM maintained relatively more stable expression levels of genes related to the ROS and Ca2+ pathways, phytohormone biosynthesis, and Na+/K+ transport. Notably, several salt resistance associated genes always showed greater levels of expression in ZM than in XJ, including a transcription factor. Consistent with the suppression of plant growth resulting from salt stress, the expression of numerous photosynthesis- and growth hormone-related genes decreased more dramatically in XJ than in ZM. By contrast, the expression levels of photosynthetic genes were lower in ZM under low-salt conditions. CONCLUSIONS: Compared with XJ, ZM is a salt-tolerant alfalfa cultivar possessing specific regulatory mechanisms conferring exceptional salt tolerance, likely by maintaining high transcript levels of abiotic and biotic stress resistance-related genes. Our results suggest that maintaining this specific physiological status and/or plant adaptation to salt stress most likely arises by inhibition of plant growth in ZM through plant hormone interactions. This study identifies new candidate genes that may regulate alfalfa tolerance to salt stress and increases the understanding of the genetic basis for salt tolerance. PMID- 29448941 TI - Traditional healing practices in rural Bangladesh: a qualitative investigation. AB - BACKGROUND: Traditional healing practice is an important and integral part of healthcare systems in almost all countries of the world. Very few studies have addressed the holistic scenario of traditional healing practices in Bangladesh, although these serve around 80% of the ailing people. This study explored distinctive forms of traditional healing practices in rural Bangladesh. METHODS: During July to October 2007, the study team conducted 64 unstructured interviews, and 18 key informant interviews with traditional healers and patients from Bhabanipur and Jobra, two adjacent villages in Chittagong district, Bangladesh. The study also used participatory observations of traditional healing activities in the treatment centers. RESULTS: Majority of the community members, especially people of low socioeconomic status, first approached the traditional healers with their medical problems. Only after failure of such treatment did they move to qualified physicians for modern treatment. Interestingly, if this failed, they returned to the traditional healers. This study identified both religious and non religious healing practices. The key religious healing practices reportedly included Kalami, Bhandai, and Spiritual Healing, whereas the non-religious healing practices included Sorcery, Kabiraji, and Home Medicine. Both patients and healers practiced self-medication at home with their indigenous knowledge. Kabiraji was widely practiced based on informal use of local medicinal plants in rural areas. Healers in both Kalami and Bhandari practices resorted to religious rituals, and usually used verses of holy books in healing, which required a firm belief of patients for the treatment to be effective. Sorcerers deliberately used their so-called supernatural power not only to treat a patient but also to cause harm to others upon secret request. The spiritual healing reportedly diagnosed and cured the health problems through communication with sacred spirits. Although the fee for diagnosis was small, spiritual healing required different types of treatment instruments, which made the treatment implicitly expensive. CONCLUSIONS: Traditional healing was widely practiced as the means of primary healthcare in rural areas of Bangladesh, especially among the people with low socioeconomic status. The extent of services showed no decline with the advancement of modern medical sciences; rather it has increased with the passage of time. PMID- 29448942 TI - Cold exposure induced oxidative stress and apoptosis in the myocardium by inhibiting the Nrf2-Keap1 signaling pathway. AB - BACKGROUND: Exposure to cold weather is associated with infaust cardiovascular responses, including myocardial infarction and arrhythmias. However, the exact mechanisms of these adverse changes in the myocardium under cold stress are unknown. This study was designed to investigate the mechanisms of cardiac injury induced by cold stress in mice. METHODS: The mice were randomly divided into three groups, normal control (no handling), 1-week cold stress and 2-week cold stress. We observed physiological changes of the mice and morphological changes of myocardium tissues, and we measured the changes of 3'-nitrotyrosine and 4 hydroxynonenal, the expression levels of superoxide dismutase-1, superoxide dismutase-2, Bax, Bad, Bcl-2, Nuclear factor erythroid-derived 2-like 2 (Nrf2) and Kelch like-ECH-associated protein 1 (Keap1) in myocardium by western blot. Besides, we detected mRNA of superoxide dismutase-1, superoxide dismutase-2, Bax, Bad, Bcl-2, Nrf2 and Keap1 by real-time PCR. One-way analysis of variance, followed by LSD-t test, was used to compare each variable for differences among the groups. RESULTS: Echocardiography analyses demonstrated left ventricle dysfunction in the groups receiving cold stress. Histological analyses witnessed inflammation, vacuolar and eosinophilic degeneration occurred in left ventricle tissues. Western blotting results showed increased 3'-nitrotyrosine and 4 hydroxynonenal and decreased antioxidant enzymes (superoxide dismutase-1 and superoxide dismutase-2) in the myocardium. Expression of Nrf2 and Keap1 followed a downward trend under cold exposure, as indicated by western blotting and real time PCR. Expression of anti-apoptotic protein Bcl-2 also showed the same trend. In contrast, expression of pro-apoptotic proteins Bax and Bad followed an upward trend under cold exposure. The results of real-time PCR were consistent with those of western blotting. CONCLUSIONS: These findings were very significant, showing that cold exposure induced cardiac injury by inhibiting the Nrf2-Keap1 signaling pathway.

AB - BACKGROUND: Kojibiose as a prebiotic and inhibitor of alpha-glucosidase exhibits potential for a wide range of applications in the food and medicine fields; however, large-scale separation and extraction of kojibiose from nature is difficult. Sucrose phosphorylase (SPase) can be used for the production of kojibiose, and currently, SPase is only heterologously expressed in E. coli, making it unsuitable for use in the food industry. However, Bacillus subtilis is generally considered to be a safe organism potentially useful for SPase expression. RESULTS: Here, for the first time, we heterologously expressed Bifidobacterium adolescentis SPase in a food-grade B. subtilis strain. The results showed that SPase was efficiently secreted into the extracellular medium in the absence of a signal peptide. After culturing the recombinant strain in a 3 L bioreactor, crude SPase yield and activity reached 7.5 g/L and 5.3 U/mL, respectively, the highest levels reported to date. The optimal reaction conditions for kojibiose synthesis catalyzed by recombinant SPase were as follows: 0.5 M sucrose, 0.5 M glucose, 0.02 Uenzyme/mgall_substrates, pH 7.0, 50 degrees C, and 30 h. Furthermore, the substrate-conversion rate reached 40.01%, with kojibiose accounting for 104.45 g/L and selectivity for kojibiose production at 97%. CONCLUSIONS: Here, we successfully expressed SPase in B. subtilis in the absence of a signal peptide and demonstrated its secretion into the extracellular medium. Our results indicated high levels of recombinant enzyme expression, with a substrate-conversion rate of 40.01%. These results provide a basis for large scale preparation of kojibiose by the recombinant SPase. PMID- 29448944 TI - Second-line treatment for advanced NSCLC without actionable mutations: is immunotherapy the 'panacea' for all patients? AB - The therapeutic approach for the second-line treatment of patients with advanced non-small cell lung cancer (NSCLC) without actionable mutations has been revolutionized by the recent approval of new effective drugs with various mechanisms of action, including nintedanib, ramucirumab, nivolumab, pembrolizumab, atezolizumab, and afatinib. The recent network meta-analysis of Crequit et al. (BMC Medicine, 15:193, 2017) compared the effectiveness and tolerability of the second-line treatments for advanced NSCLC with wild-type or unknown status for EGFR. The authors found that immunotherapy might be more efficacious than the currently recommended treatments. However, their meta analysis does not take into account the role of predictive biomarkers - this is indeed a crucial point in the decision-making process considering that only a fraction of advanced NSCLC patients might derive a long-term benefit from second line immunotherapy. The identification of molecular biomarkers that can predict a response to immune checkpoints, angiogenesis, and EGFR inhibitors remains an important goal of clinical research in order to maximize the benefit of these agents and to aid clinicians in the decision-making process.Please see related article: https://bmcmedicine.biomedcentral.com/articles/10.1186/s12916-017-0954 x.

PMID- 29448945 TI - RNA secondary structure profiling in zebrafish reveals unique regulatory features. AB - BACKGROUND: RNA is known to play diverse roles in gene regulation. The clues for this regulatory function of RNA are embedded in its ability to fold into intricate secondary and tertiary structure. RESULTS: We report the transcriptome wide RNA secondary structure in zebrafish at single nucleotide resolution using Parallel Analysis of RNA Structure (PARS). This study provides the secondary structure map of zebrafish coding and non-coding RNAs. The single nucleotide pairing probabilities of 54,083 distinct transcripts in the zebrafish genome were documented. We identified RNA secondary structural features embedded in functional units of zebrafish mRNAs. Translation start and stop sites were demarcated by weak structural signals. The coding regions were characterized by the three-nucleotide periodicity of secondary structure and display a codon base specific structural constrain. The splice sites of transcripts were also delineated by distinct signature signals. Relatively higher structural signals were observed at 3' Untranslated Regions (UTRs) compared to Coding DNA Sequence (CDS) and 5' UTRs. The 3' ends of transcripts were also marked by unique structure signals. Secondary structural signals in long non-coding RNAs were also explored to better understand their molecular function. CONCLUSIONS: Our study presents the first PARS-enabled transcriptome-wide secondary structure map of zebrafish, which documents pairing probability of RNA at single nucleotide precision. Our findings open avenues for exploring structural features in zebrafish RNAs and their influence on gene expression.

PMID- 29448948 TI - Occupational exposure to HIV in a developing country: assessing knowledge and attitude of healthcare professional before and after an awareness symposium. AB - OBJECTIVE: Health care providers (HCPs) are at risk of occupational exposure to HIV infection. In developing world these exposure occur due to general lack of awareness, education and structured training of HCPs. The objective of the study was to asses if continuing medical education symposium can be used as an effective educational tool to improve attitude, awareness and knowledge regarding occupational exposure to HIV infection. This quasi-experimental study was conducted among HCPs from Karachi, Pakistan. After assessing the baseline knowledge, awareness, and attitude by means of pretest; HCPs were reassessed with posttest after an education symposium on occupational exposure to HIV infection. RESULTS: Among 364 participating HCPs, 14.2% had previous training on post exposure prophylaxis. There was an overall statistically significant (P value < 0.001) improvement in the attitude of the participants. A statistically positive improvement in the number of participants giving correct answer was observed in 9 out of 11 questions (P value < 0.001). The mean score of participants' knowledge before intervention was 6.44 +/- 1.84, which improved to 8.82 +/- 2.17. Along with the increase in knowledge, a positive change in the attitude regarding safety against HIV was observed after the education symposium. PMID- 29448949 TI - A standardized framework for representation of ancestry data in genomics studies, with application to the NHGRI-EBI GWAS Catalog. AB - The accurate description of ancestry is essential to interpret, access, and integrate human genomics data, and to ensure that these benefit individuals from all ancestral backgrounds. However, there are no established guidelines for the representation of ancestry information. Here we describe a framework for the accurate and standardized description of sample ancestry, and validate it by application to the NHGRI-EBI GWAS Catalog. We confirm known biases and gaps in diversity, and find that African and Hispanic or Latin American ancestry populations contribute a disproportionately high number of associations. It is our hope that widespread adoption of this framework will lead to improved analysis, interpretation, and integration of human genomics data. PMID- 29448950 TI - Identification and characterization of microRNA in the lung tissue of pigs with different susceptibilities to PCV2 infection. AB - Porcine circovirus type 2 (PCV2) is the primary cause of post-weaning multisystemic wasting syndrome (PMWS) and other PCV-associated diseases. According to our previous RNA-sequencing analysis, the differences in the susceptibility to PCV2 infection depended on the genetic differences between the Laiwu (LW) and Yorkshire * Landrace crossbred (YL) pigs, but the cellular microRNA (miRNA) that are differentially expressed between the LW and YL pigs before and after PCV2 infection remain to be determined. In this study, high throughput sequencing was performed to determine the abundance and differential expression of miRNA in lung tissues from PCV2-infected and PCV2-uninfected LW and YL pigs. In total, 295 known and 95 novel miRNA were identified, and 23 known and 25 novel miRNA were significantly differentially expressed in the PCV2-infected vs. PCV2-uninfected LW pigs and/or the PCV2-infected vs. PCV2-uninfected YL pigs. The expression levels of ssc-miR-122, ssc-miR-192, ssc-miR-451, ssc-miR-486, and ssc-miR-504 were confirmed by quantitative real-time PCR (qRT-PCR). Analysis of the potential targets of the four up-regulated miRNA (i.e., ssc-miR-122, ssc-miR 192, ssc-miR-451 and ssc-miR-486) identified pathways and genes that may be important for disease resistance. Among the up-regulated miRNA, ssc-miR-122 can repress the protein expression and viral DNA replication of PCV2 and down regulate the expression of the nuclear factor of activated T-cells 5 (NFAT5) and aminopeptidase puromycin sensitive (NPEPPS) by binding to their 3' untranslated region (3'UTR) in PK15 cells. Therefore, ssc-miR-122 may indirectly suppress PCV2 infection by targeting genes related to the host immune system, such as NFAT5 and NPEPPS. PMID- 29448951 TI - T-ARMS PCR genotyping of SNP rs445709131 using thermostable strand displacement polymerase. AB - OBJECTIVES: In a recent publication, we reported the successful use of tetra primer-amplification refractory mutation system based polymerase chain reaction (T-ARMS-PCR) for genotyping of rs445709131-SNP responsible for the bovine leukocyte adhesion deficiency (BLAD) in cattle. The SNP is characterized by higher GC content of the surrounding region, hence, the previous protocol utilized dimethyl sulfoxide as PCR enhancer. Here, the reaction cocktail was modified with the use of thermostable strand displacement polymerase (SD polymerase) instead of commonly used Taq DNA Polymerase. The amplification efficiency, reaction sensitivity, specificity, and need of PCR enhancer in reactions containing SD polymerase and Taq polymerase were compared. RESULTS: T ARMS-PCR assay is influenced by multiple factors for the correct genotyping necessitating extensive optimization at the initial stages. The described modification enabled generation of all amplicons by 25 cycles whereas the assay with Taq polymerase needed a minimum of 35 cycles. The modified assay amplified all amplicons at a wider range of annealing temperature (50-60 degrees C), without the addition of dimethyl sulfoxide. The replacement of Taq polymerase with SD polymerase may be beneficial in the T-ARMS assay for development of user friendly, faster assay which is less affected by the reaction and cyclic conditions. PMID- 29448952 TI - A survey of workplace violence against physicians in the hospitals, Myanmar. AB - OBJECTIVE: Workplace violence in hospitals is recently becoming a major global concern in many countries. However, in Myanmar, we have felt that patients and their families have rarely made unreasonable complaints in hospitals, and then, the purpose of this study is to report the current state of workplace violence in hospitals in Myanmar. Participants are 196 physicians (108 males and 88 females) in hospitals in Myanmar. RESULTS: A descriptive survey was conducted in regard to verbal abuse and physical violence from patients or the people concerned. At the results of this study, the percentages of physicians who have encountered verbal abuse and those who have encountered physical violence are markedly low (8.7 and 1.0%, respectively). The present study is the first to report the frequencies of verbal abuse and physical violence against physicians in a least developed country, and the results of the present study are important in terms of discussing workplace violence in hospitals. PMID- 29448953 TI - Clinical prevalence of Lewy body dementia. AB - BACKGROUND: The prevalence of dementia with Lewy bodies (DLB) and dementia in Parkinson's disease (PDD) in routine clinical practice is unclear. Prevalence rates observed in clinical and population-based cohorts and neuropathological studies vary greatly. Small sample sizes and methodological factors in these studies limit generalisability to clinical practice. METHODS: We investigated prevalence in a case series across nine secondary care services over an 18-month period, to determine how commonly DLB and PDD cases are diagnosed and reviewed within two regions of the UK. RESULTS: Patients with DLB comprised 4.6% (95% CI 4.0-5.2%) of all dementia cases. DLB was represented in a significantly higher proportion of dementia cases in services in the North East (5.6%) than those in East Anglia (3.3%; chi2 = 13.6, p < 0.01). DLB prevalence in individual services ranged from 2.4 to 5.9%. PDD comprised 9.7% (95% CI 8.3-11.1%) of Parkinson's disease cases. No significant variation in PDD prevalence was observed between regions or between services. CONCLUSIONS: We found that the frequency of clinical diagnosis of DLB varied between geographical regions in the UK, and that the prevalence of both DLB and PDD was much lower than would be expected in this case series, suggesting considerable under-diagnosis of both disorders. The significant variation in DLB diagnostic rates between these two regions may reflect true differences in disease prevalence, but more likely differences in diagnostic practice. The systematic introduction of more standardised diagnostic practice could improve the rates of diagnosis of both conditions. PMID- 29448955 TI - Analysis of the genetic diversity and mRNA expression level in porcine reproductive and respiratory syndrome virus vaccinated pigs that developed short or long viremias after challenge. AB - Porcine reproductive and respiratory syndrome virus (PRRSv) infection alters the host's cellular and humoral immune response. Immunity against PRRSv is multigenic and vary between individuals. The aim of the present study was to compare several genes that encode for molecules involved in the immune response between two groups of vaccinated pigs that experienced short or long viremic periods after PRRSv challenge. These analyses include the sequencing of four SLA Class I, two Class II allele groups, and CD163, plus the analysis by quantitative realtime qRT PCR of the constitutive expression of TLR2, TLR3, TLR4, TLR7, TLR8 and TLR9 mRNA and other molecules in peripheral blood mononuclear cells. PMID- 29448954 TI - New therapeutic strategies to treat human cancers expressing mutant p53 proteins. AB - The tumor suppressor p53 plays a critical role to preserve DNA fidelity from diverse insults through the regulation of cell-cycle checkpoints, DNA repair, senescence and apoptosis. The TP53 is the most frequently inactivated gene in human cancers. This leads to the production of mutant p53 proteins that loose wild-type p53 tumor suppression functions and concomitantly acquire new oncogenic properties among which deregulated cell proliferation, increased chemoresistance, disruption of tissue architecture, promotion of migration, invasion and metastasis and several other pro-oncogenic activities. Mouse models show that the genetic reconstitution of the wild type p53 tumor suppression functions rescues tumor growth. This strongly supports the notion that either restoring wt-p53 activity or inhibiting mutant p53 oncogenic activity could provide an efficient strategy to treat human cancers. In this review we briefly summarize recent advances in the study of small molecules and compounds that subvert oncogenic activities of mutant p53 protein into wt-p53 tumor suppressor functions. We highlight inhibitors of signaling pathways aberrantly modulated by oncogenic mutant p53 proteins as promising therapeutic strategies. Finally, we consider the clinical applications of compounds targeting mutant p53 and the use of currently available drugs in the treatment of tumors expressing mutant p53 proteins. PMID- 29448956 TI - Immunomodulatory plasticity of mesenchymal stem cells: a potential key to successful solid organ transplantation. AB - Organ transplantation remains to be a treatment of choice for patients suffering from irreversible organ failure. Immunosuppressive (IS) drugs employed to maintain the allograft have shown excellent short-term graft survival, but, their long-term use could contribute to immunological and non-immunological risk factors, resulting in graft dysfunctionalities. Upcoming IS regimes have highlighted the use of cell-based therapies, which can eliminate the risk of drug borne toxicities while maintaining efficacy of the treatment. Mesenchymal stem cells (MSCs) have been considered as an invaluable cell type, owing to their unique immunomodulatory properties, which makes them desirable for application in transplant settings, where hyper-activation of the immune system is evident. The immunoregulatory potential of MSCs holds true for preclinical studies while achieving it in clinical studies continues to be a challenge. Understanding the biological factors responsible for subdued responses of MSCs in vivo would allow uninhibited use of this therapy for countless conditions. In this review, we summarize the variations in the preclinical and clinical studies utilizing MSCs, discuss the factors which might be responsible for variability in outcome and propose the advancements likely to occur in future for using this as a "boutique/personalised therapy" for patient care. PMID- 29448958 TI - Antigenic and functional profiles of a Lawsonia intracellularis protein that shows a flagellin-like trait and its immuno-stimulatory assessment. AB - The obligate intracellular Lawsonia intracellularis (LI), the etiological agent of proliferative enteropathy (PE), is an economically important disease in the swine industry. Due to extreme difficulty of in vitro culture of the pathogen, molecular characterization of protein components of LI that are targets of the immune system, is difficult; thus, the scientific evidence to drive the development of preventive measures is lacking. In this work, we investigated the antigenic and functional characteristics of a putative flagellar-associated protein, LI0570, using in silico computational approaches for epitope prediction and an in vitro protein-based molecular assay. The amino acid sequence of LI0570 exhibited similarities to flagellar-associated proteins in four different bacterial strains. The presence of B cell linear confirmative epitopes of the protein predicted by a bioinformatics tool was validated by western blot analysis using anti-LI mouse hyperimmune serum, which implied that LI0570 induced production of antigen-specific antibodies in vivo. Further, TLR5-stimulating activity and IL-8 cytokine expression produced via downstream signaling were observed in HEK-BlueTM-hTLR5 cells stimulated with LI0570. This result indicates that the LI0570 protein can trigger an innate immune response followed by a T cell-related adaptive immune response in an infected host. Collectively, the data presented here support that the LI0570 protein which shows the antigenic potential could be a useful component of a recombinant vaccine against PE, providing progress toward an effective prevention strategy. PMID- 29448957 TI - Brain region-specific enhancement of remyelination and prevention of demyelination by the CSF1R kinase inhibitor BLZ945. AB - Multiple sclerosis (MS) is a chronic inflammatory disease affecting the central nervous system (CNS). While multiple effective immunomodulatory therapies for MS exist today, they lack the scope of promoting CNS repair, in particular remyelination. Microglia play a pivotal role in regulating myelination processes, and the colony-stimulating factor 1 (CSF-1) pathway is a key regulator for microglia differentiation and survival. Here, we investigated the effects of the CSF-1 receptor kinase inhibitor, BLZ945, on central myelination processes in the 5-week murine cuprizone model by non-invasive and longitudinal magnetic resonance imaging (MRI) and histology. Therapeutic 2-week BLZ945 treatment caused a brain region-specific enhancement of remyelination in the striatum/cortex, which was absent in the corpus callosum/external capsule. This beneficial effect correlated positively with microglia reduction, increased oligodendrocytes and astrogliosis. Prophylactic BLZ945 treatment prevented excessive demyelination in the corpus callosum by reducing microglia and increasing oligondendrocytes. In the external capsule oligodendrocytes were depleted but not microglia and a buildup of myelin debris and axonal damage was observed. A similar microglial dysfunction in the external capsule with an increase of myelin debris was obvious in triggering receptor expressed on myeloid cells 2 (TREM2) knock-out mice treated with cuprizone. Finally, therapeutic BLZ945 treatment did not change the disease course in experimental autoimmune encephalomyelitis mice, a peripherally driven neuroinflammation model. Taken together, our data suggest that a short-term therapeutic inhibition of the CSF-1 receptor pathway by BLZ945 in the murine cuprizone model enhances central remyelination by modulating neuroinflammation. Thus, microglia-modulating therapies could be considered clinically for promoting myelination in combination with standard-of-care treatments in MS patients. PMID- 29448960 TI - Double-negative (CD27-IgD-) B cells are expanded in NSCLC and inversely correlate with affinity-matured B cell populations. AB - BACKGROUND: The presence of B cells in early stage non-small cell lung cancer (NSCLC) is associated with longer survival, however, the role these cells play in the generation and maintenance of anti-tumor immunity is unclear. B cells differentiate into a variety of subsets with differing characteristics and functions. To date, there is limited information on the specific B cell subsets found within NSCLC. To better understand the composition of the B cell populations found in NSCLC we have begun characterizing B cells in lung tumors and have detected a population of B cells that are CD79A+CD27-IgD-. These CD27 IgD- (double-negative) B cells have previously been characterized as unconventional memory B cells and have been detected in some autoimmune diseases and in the elderly population but have not been detected previously in tumor tissue. METHODS: A total of 15 fresh untreated NSCLC tumors and 15 matched adjacent lung control tissues were dissociated and analyzed by intracellular flow cytometry to detect the B cell-related markers CD79A, CD27 and IgD. All CD79A+ B cells subsets were classified as either naive (CD27-IgD+), affinity-matured (CD27+IgD-), early memory/germinal center cells (CD27+IgD+) or double-negative B cells (CD27-IgD-). Association of double-negative B cells with clinical data including gender, age, smoking status, tumor diagnosis and pathologic differentiation status were also examined using the logistic regression analysis for age and student's t-test for all other variables. Associations with other B cell subpopulations were examined using Spearman's rank correlation. RESULTS: We observed that double-negative B cells were frequently abundant in lung tumors compared to normal adjacent controls (13 out of 15 cases), and in some cases made up a substantial proportion of the total B cell compartment. The presence of double-negative cells was also found to be inversely related to the presence of affinity-matured B cells within the tumor, Spearman's coefficient of - 0.76. CONCLUSIONS: This study is the first to observe the presence of CD27-IgD- double negative B cells in human NSCLC and that this population is inversely correlated with traditional affinity-matured B cell populations. PMID- 29448959 TI - Impaired T cell-mediated hepatitis in peroxisome proliferator activated receptor alpha (PPARalpha)-deficient mice. AB - BACKGROUND: Peroxisome proliferator activated receptor alpha (PPARalpha), a regulator of enzymes involved in beta oxidation, has been reported to influence lymphocyte activation. The purpose of this study was to determine whether PPARalpha plays a role in T cell-mediated hepatitis induced by Concanavalin A (ConA). METHODS: Wild type (wt) or PPARalpha-deficient (PPARalpha-/-) mice were treated with ConA (15 mg/kg) by intravenous injection 0, 10 or 24 h prior to sacrifice and serum and tissue collection for analysis of tissue injury, cytokine response, T cell activation and characterization. RESULTS: Ten and 24 h following ConA administration, wt mice had significant liver injury as demonstrated by serum transaminase levels, inflammatory cell infiltrate, hepatocyte apoptosis, and expression of several cytokines including interleukin 4 (IL4) and interferon gamma (IFNgamma). In contrast, PPARalpha-/- mice were protected from ConA-induced liver injury with significant reductions in serum enzyme release, greatly reduced inflammatory cell infiltrate, hepatocellular apoptosis, and IFNgamma expression, despite having similar levels of hepatic T cell activation and IL4 expression. This resistance to liver injury was correlated with reduced numbers of hepatic natural killer T (NKT) cells and their in vivo responsiveness to alpha galactosylceramide. Interestingly, adoptive transfer of either wt or PPARalpha-/- splenocytes reconstituted ConA liver injury and cytokine production in lymphocyte deficient, severe combined immunodeficient mice implicating PPARalpha within the liver, possibly through support of IL15 expression and/or suppression of IL12 production and not the lymphocyte as the key regulator of T cell activity and ConA-induced liver injury. CONCLUSION: Taken together, these data suggest that PPARalpha within the liver plays an important role in ConA-mediated liver injury through regulation of NKT cell recruitment and/or survival. PMID- 29448961 TI - Nuclear receptor agonist-driven modification of inflammation and amyloid pathology enhances and sustains cognitive improvements in a mouse model of Alzheimer's disease. AB - BACKGROUND: Alzheimer's disease (AD) is a highly prevalent neurodegenerative disorder characterized by pathological hallmarks of beta-amyloid plaque deposits, tau pathology, inflammation, and cognitive decline. Treatment remains a clinical obstacle due to lack of effective therapeutics. Agonists targeting nuclear receptors, such as bexarotene, reversed cognitive deficits regardless of treatment duration and age in murine models of AD. While bexarotene demonstrated marked efficacy in decreasing plaque levels following short-term treatment, prolonged treatment did not modulate plaque burden. This suggested that plaques might reform in mice treated chronically with bexarotene and that cessation of bexarotene treatment before plaques reform might alter amyloid pathology, inflammation, and cognition in AD mice. METHODS: We utilized one-year-old APP/PS1 mice that were divided into two groups. We treated one group of mice for 2 weeks with bexarotene. The other group of mice was treated for 2 weeks with bexarotene followed by withdrawal of drug treatment for an additional 2 weeks. Cognition was evaluated using the novel-object recognition test either at the end of bexarotene treatment or the end of the withdrawal period. We then analyzed amyloid pathology and microgliosis at the conclusion of the study in both groups. RESULTS: Bexarotene treatment enhanced cognition in APP/PS1 mice similar to previous findings. Strikingly, we observed sustained cognitive improvements in mice in which bexarotene treatment was discontinued for 2 weeks. We observed a sustained reduction in microgliosis and plaque burden following drug withdrawal exclusively in the hippocampus. CONCLUSIONS: Our findings demonstrate that bexarotene selectively modifies aspects of neuroinflammation in a region-specific manner to reverse hippocampal-dependent cognitive deficits in AD mice and may provide insight to inform future studies with nuclear receptor agonists. PMID- 29448963 TI - Academic medical centers as innovation ecosystems to address population -omics challenges in precision medicine. AB - While the promise of the Human Genome Project provided significant insights into the structure of the human genome, the complexities of disease at the individual level have made it difficult to utilize -omic information in clinical decision making. Some of the existing constraints have been minimized by technological advancements that have reduced the cost of sequencing to a rate far in excess of Moore's Law (a halving in cost per unit output every 18 months). The reduction in sequencing costs has made it economically feasible to create large data commons capturing the diversity of disease across populations. Until recently, these data have primarily been consumed in clinical research, but now increasingly being considered in clinical decision- making. Such advances are disrupting common diagnostic business models around which academic medical centers (AMCs) and molecular diagnostic companies have collaborated over the last decade. Proprietary biomarkers and patents on proprietary diagnostic content are no longer driving biomarker collaborations between industry and AMCs. Increasingly the scope of the data commons and biorepositories that AMCs can assemble through a nexus of academic and pharma collaborations is driving a virtuous cycle of precision medicine capabilities that make an AMC relevant and highly competitive. A rebalancing of proprietary strategies and open innovation strategies is warranted to enable institutional precision medicine asset portfolios. The scope of the AMC's clinical trial and research collaboration portfolios with industry are increasingly dependent on the currency of data, and less on patents. Intrapeneurial support of internal service offerings, clinical trials and clinical laboratory services for example, will be important new points of emphasis at the academic-industry interface. Streamlining these new models of industry collaboration for AMCs are a new area for technology transfer offices to offer partnerships and to add value beyond the traditional intellectual property offering. PMID- 29448964 TI - Utility of rituximab treatment for exophthalmos, myxedema, and osteoarthropathy syndrome resistant to corticosteroids due to Graves' disease: a case report. AB - BACKGROUND: Exophthalmos, myxedema, and osteoarthropathy syndrome is a very rare condition that is associated with Graves' disease. The presence of dermopathy and the involvement of joint/bone tissues indicate that it seems to be related with the severity of the autoimmune process. Owing to its low incidence, there is a lack of information regarding its treatment and clinical follow-up. Some cases improved after use of high doses of steroids; however, some patients do not respond to this treatment. Recently, the effectiveness of rituximab for treatment of Graves' ophthalmopathy resistant to corticosteroids has been demonstrated. However, it has never been used for the treatment of exophthalmos, myxedema, and osteoarthropathy syndrome (particularly for the treatment of osteoarticular manifestations). CASE PRESENTATION: We present the case of a 54-year-old Mexican woman previously treated for Graves' disease who developed post-iodine hypothyroidism and exophthalmos, myxedema, and osteoarthropathy that did not improve after high doses of steroids (intravenous and oral). Her exophthalmos, myxedema, and osteoarthropathy syndrome symptoms improved as early as 6 months after treatment with rituximab. CONCLUSION: Exophthalmos, myxedema, and osteoarthropathy syndrome is a non-classical presentation of Graves' disease, whose clinical manifestations could improve after treatment with rituximab, particularly in those patients with lack of response to high doses of corticosteroids. PMID- 29448962 TI - Non-viral gene delivery systems for tissue repair and regeneration. AB - Critical tissue defects frequently result from trauma, burns, chronic wounds and/or surgery. The ideal treatment for such tissue loss is autografting, but donor sites are often limited. Tissue engineering (TE) is an inspiring alternative for tissue repair and regeneration (TRR). One of the current state-of the-art methods for TRR is gene therapy. Non-viral gene delivery systems (nVGDS) have great potential for TE and have several advantages over viral delivery including lower immunogenicity and toxicity, better cell specificity, better modifiability, and higher productivity. However, there is no ideal nVGDS for TRR, hence, there is widespread research to improve their properties. This review introduces the basic principles and key aspects of commonly-used nVGDSs. We focus on recent advances in their applications, current challenges, and future directions. PMID- 29448965 TI - Temporo-spatial dynamics and behavioural patterns of 2012 cholera epidemic in the African mega-city of Conakry, Guinea. AB - BACKGROUND: Cholera is endemic in Guinea, having suffered consecutive outbreaks from 2004 to 2008 followed by a lull until the 2012 epidemic. Here we describe the temporal-spatial and behavioural characteristics of cholera cases in Conakry during a three-year period, including the large-scale 2012 epidemic. METHODS: We used the national and African Cholera Surveillance Network (Africhol) surveillance data collected from every cholera treatment centre in Conakry city from August 2011 to December 2013. The prevalence of suspect and confirmed cholera cases, the case fatality ratio (CFR), and the factors associated with suspected cholera were described according to three periods: pre-epidemic (A), epidemic 2012 (B) and post epidemic (C). Weekly attack rates and temporal-spatial clustering were calculated at municipality level for period B. Cholera was confirmed by culture at the cholera national reference laboratory. RESULTS: A total of 4559 suspect cases were reported: 66, 4437, and 66 suspect cases in periods A, B and C, respectively. Among the 204 suspect cases with culture results available, 6%, 60%, and 70% were confirmed in periods A, B, and C, respectively. With 0.3%, the CFR was significantly lower in period B than in periods A (7.6%) and C (7.1%). The overall attack rate was 0.28% in period B, ranging from 0.17% to 0.31% across municipalities. Concomitantly, a cluster of cases was identified in two districts in the northern part of Conakry. At 14%, rice water stools were less frequent in period A than in period B and C (78% and 84%). Dehydration (31% vs 94% and 89%) and coma (0.4% vs 3.1% and 2.9%) were lower during period B than in periods A and C. The treatment of drinking water was less frequent in period A, while there were more reports of recent travel in period C. CONCLUSIONS: The epidemic dynamic and the sociological description of suspect cases before, during, and after the large-scale epidemic revealed that the Vibrio cholerae was already present before the epidemic. However, it appeared that infected individuals reacted differently in terms of disease severity as well as their access to treated water and travel habits. Such an in-depth description of cholera epidemics should be systematically carried out in cholera endemic settings in order to prioritize higher risk areas, identify transmission factors, and optimize preventive interventions. PMID- 29448966 TI - Exosomes taken up by neurons hijack the endosomal pathway to spread to interconnected neurons. AB - In Alzheimer disease and related disorders, the microtubule-associated protein tau aggregates and forms cytoplasmic lesions that impair neuronal physiology at many levels. In addition to affecting the host neuron, tau aggregates also spread to neighboring, recipient cells where the misfolded tau aggregates, in a manner similar to prions, actively corrupt the proper folding of soluble tau, and thereby impair cellular functions. One vehicle for the transmission of tau aggregates are secretory nanovesicles known as exosomes. Here, we established a simple model of a neuronal circuit using a microfluidics culture system in which hippocampal neurons A and B were seeded into chambers 1 and 2, respectively, extending axons via microgrooves in both directions and thereby interconnecting. This system served to establish two models to track exosome spreading. In the first model, we labeled the exosomal membrane by coupling tetraspanin CD9 with either a green or red fluorescent tag. This allowed us to reveal that interconnected neurons exchange exosomes only when their axons extend in close proximity. In the second model, we added exosomes isolated from the brains of tau transgenic rTg4510 mice (i.e. exogenous, neuron A-derived) to neurons in chamber 1 (neuron B) interconnected with neuron C in chamber 2. This allowed us to demonstrate that a substantial fraction of the exogenous exosomes were internalized by neuron B and passed then on to neuron C. This transportation from neuron B to C was achieved by a mechanism that is consistent with the hijacking of secretory endosomes by the exogenous exosomes, as revealed by confocal, super resolution and electron microscopy. Together, these findings suggest that fusion events involving the endogenous endosomal secretory machinery increase the pathogenic potential and the radius of action of pathogenic cargoes carried by exogenous exosomes. PMID- 29448967 TI - Facial nerve stimulation in normal pigs and healthy human volunteers: transitional development of a medical device for the emergency treatment of ischemic stroke. AB - BACKGROUND: Magnetic stimulation of the facial nerve has been tested in preclinical studies as a new, non-invasive emergency treatment of ischemic stroke that acts by increasing cerebral blood flow (CBF). The objective of the studies reported herein was to identify minimal stimulation parameters that increase CBF in large animals and then test those stimulation parameters in healthy volunteers for safety, tolerability, and effectiveness at increasing CBF. This translational research is necessary preparation for clinical studies in ischemic stroke patients. METHODS: Initial experiments in anesthetized Yorkshire pigs were undertaken in order to identify the lowest stimulus power and duration that increase CBF. A full 3 * 3 factorial design was used to evaluate magnetic stimulation of the facial nerve at various stimulation powers (1.3, 1.6, and 1.9 Tesla field strength at coil surface) and for various durations (2, 3.5, and 5 min). CBF was measured with contrast MRI perfusion imaging and the internal carotid arteries were assessed with MR angiography. Magnetic facial nerve stimulation with parameters identified in the pig study was then applied to 35 healthy volunteers. Safety was assessed with adverse event reports and by medical examination. Tolerability was defined as each volunteer's ability to withstand at least 2 min of stimulation. Volunteers could determine the maximum power of stimulation they received during a ramp-up period. RESULTS: In pigs, unilateral facial nerve stimulation increased CBF by as much as 77% over pre-stimulation baseline when administered across a range of 1.3-1.9 Tesla power and for 2- to 5 min duration. No clear dose-response relationship could be observed across this range, but lower powers and durations than these were markedly less effective. The effect of a single stimulation lasted 90 min. A second stimulation delivered 100 min after the first stimulation sustained the increased CBF without evidence of tachyphylaxis. In human, bilateral facial nerve stimulation caused only non serious adverse events that were limited to the 2-min stimulation period. Tolerability was greatly improved by gentle encouragement from the study staff, which enabled most volunteers to tolerate 1.6-1.8 Tesla of stimulation power. CBF measures taken approximately 10 min after stimulation demonstrated on average a 32 +/- 6% increase in CBF, with >= 25% increases in CBF occurring in 10 of the 31 volunteers who had adequate CBF measurements. CONCLUSIONS: The minimal effective stimulation parameters defined by increased CBF, as identified in the pig study, translated into safe, tolerable, and effective stimulation of healthy volunteers. These results support the future development and evaluation of non-invasive facial nerve stimulation for the emergency treatment of ischemic stroke.

AB - BACKGROUND: The Global Burden of Disease estimates that approximately a third of deaths worldwide are attributable to behavioural risk factors that, at their core, have the consumption of unhealthful products and exposures produced by profit driven commercial entities. We use Steven Lukes' three-dimensional view of power to guide the study of the practices deployed by commercial interests to foster the consumption of these commodities. Additionally, we propose a framework to systematically study corporations and other commercial interests as a distal, structural, societal factor that causes disease and injury. Our framework offers a systematic approach to mapping corporate activity, allowing us to anticipate and prevent actions that may have a deleterious effect on population health. CONCLUSION: Our framework may be used by, and can have utility for, public health practitioners, researchers, students, activists and other members of civil society, policy makers and public servants in charge of policy implementation. It can also be useful to corporations who are interested in identifying key actions they can take towards improving population health. PMID- 29448970 TI - Dementia clinical trial implications of mild behavioral impairment. AB - The World Alzheimer Report 2016 estimated that 47 million people are living with dementia worldwide (Alzheimer's Disease International, 2016). In the inaugural World Health Organization Ministerial Conference on Global Action against Dementia, six of the top ten research priorities were focused on prevention, identification, and reduction of dementia risk, and on delivery and quality of care for people with dementia and their carers (Shah et al., 2016). While the Lancet Neurology Commission has suggested that even minor advances to delay progression or ameliorate symptoms might have substantial financial and societal benefits (Winblad et al., 2016), advances have been slow. PMID- 29448969 TI - Prevalence of erectile dysfunction and associated factors among diabetic men attending the diabetic clinic at Felege Hiwot Referral Hospital, Bahir Dar, North West Ethiopia, 2016. AB - OBJECTIVE: Even though several scholars have conducted study in different part of the world on erectile dysfunction in patients diagnosed with diabetes mellitus, it's magnitude vary among their finding with the range between 20 and 90%. This study aimed at assessing the prevalence of erectile dysfunction and associated factors among diabetic clients. RESULTS: A cross sectional study was conducted from January 2016 to March, 2016. Systematic random sampling technique was used. Data were collected using a structured questionnaire and level of erectile dysfunction was measured using the international index of erectile function. A total of 422 diabetic patients were participated with 100% response rate. The proportion of erectile dysfunction was 85.5% and it was significantly associated with higher age (AOR: 6.46, 95% CI 2.55-16.44) and Diabetic complication (AOR: 3.97, 95% CI 1.06-17.36). Therefore, screening for ED in diabetic patients, particularly for those who are in advanced age and living with DM for more than 10 years is needed for it's early detection, prevention and management.

PMID- 29448972 TI - Bullying and sexual harassment of junior doctors in New South Wales, Australia: rate and reporting outcomes. AB - Objective The aim of this study was to describe rates of exposure to bullying and sexual harassment in junior doctors in first- or second-year prevocational medical training (PGY1 or PGY2 respectively) positions in New South Wales (NSW) and the Australian Capital Territory (ACT), and to explore the types of actions taken in response.Methods A cross-sectional survey of junior doctors in PGY1 or PGY2 positions was undertaken in 2015 and 2016 (n=374 and 440 respectively). Thematic analysis was undertaken on free-text responses to describe the reporting process and outcomes in more depth.Results The estimated response rate was 17 20%. Results from both surveys followed almost identical trends. Most respondents in 2015 and 2016 reported being bullied (n=203 (54.3%) and 253 (57.5%) respectively), 16-19% reported sexual harassment (n=58 and 82 respectively) and 29% of females reported sexual harassment. Qualitative analysis elucidated reasons for not taking action in response to bullying and harassment, including workplace normalisation of these behaviours, fear of reprisal and lack of knowledge or confidence in the reporting process. For respondents who did take action, most reported ineffective or personally harmful outcomes when reporting to senior colleagues, including being dismissed or blamed, and an intention not to trust the process in the future.Conclusions The findings suggest that interventions targeted at the level of junior doctors to improve the culture of bullying and harassment in medicine are unlikely to be helpful. Different approaches that address the problem in a more systemic way are needed, as is further research about the effectiveness of such interventions.What is known about the topic? Bullying and sexual harassment are common workplace experiences in the medical profession.What does this paper add? Over half the junior doctors in the present study experienced bullying and nearly one-fifth experienced sexual harassment. Junior doctors are reluctant to speak out, not only for fear of reprisal, but also because they do not believe it is worth doing so.What are the implications for practitioners? The data confirm a systemic problem of bullying in NSW. Primarily focusing on interventions with junior doctors (e.g. resilience training) is unlikely to solve the problem. Different and multipronged approaches (e.g. raising awareness in senior colleagues and training bystanders to intervene) should be tried and studied. PMID- 29448973 TI - cAMP response element-binding protein 1 controls porcine ovarian cell proliferation, apoptosis, and FSH and insulin-like growth factor 1 response. AB - The aim of the present study was to examine the role of cAMP response element binding protein (CREB) and its phosphorylation in the regulation of ovarian cell proliferation and apoptosis, and of the response of proliferation and apoptosis to the upstream hormonal stimulators FSH and insulin-like growth factor (IGF) 1. In the first series of experiments, porcine ovarian granulosa cells, transfected or not with a gene construct encoding wild-type CREB1 (CREB1WT), were cultured with and without FSH (0, 1, 10 or 100ngmL-1). In the second series of experiments, these cells were transfected or not with CREB1WT or non phosphorylatable mutant CREB1 (CREB1M1) and cultured with and without FSH (0, 1, 10 or 100ngmL-1) or IGF1 (0, 1, 10 and 100ngmL-1). Levels of total and phosphorylated (p-) CREB1, proliferating cell nuclear antigen (PCNA), a marker of proliferation, and BAX, a marker of apoptosis, were evaluated by western immunoblotting and immunocytochemical analysis. Transfection of cells with CREB1WT promoted accumulation of total CREB1 within cells, but p-CREB1 was not detected in any cell group. Both CREB1WT and CREB1M1 reduced cell proliferation and apoptosis. Addition of 10 and 100ngmL-1 FSH to non-transfected cells promoted CREB1 accumulation and apoptosis, whereas cell proliferation was promoted by all concentrations of FSH tested. FSH activity was not modified in cells transfected with either CREB1WT or CREB1M1. IGF1 at 100ngmL-1 promoted cell proliferation, whereas all concentrations of IGF1 tested reduced apoptosis. Transfection with either CREB1WT or CREB1M1 did not modify the effects of either FSH or IGF1, although CREB1M1 reversed the effect of IGF1 on apoptosis from inhibitory to stimulatory. These observations suggest that CREB1 is involved in the downregulation of porcine ovarian cell proliferation and apoptosis. The absence of visible CREB1 phosphorylation and the similarity between the effects of CREB1WT and CREB1M1 transfection indicate that phosphorylation is not necessary for CREB1 action on these processes. Furthermore, the observations suggest that FSH promotes both ovarian cell proliferation and apoptosis, whereas IGF1 has proliferation-promoting and antiapoptotic properties. The effect of FSH on CREB1 accumulation and the ability of CREB1M1 to reverse the effects of IGF1 on apoptosis indicate that CREB1 is a mediator of hormonal activity, but the inability of either CREB1WT or CREBM1transfection to modify the primary effects of FSH and IGF1 suggest that CREB1 and its phosphorylation do not mediate the action of these hormones on ovarian cell proliferation and apoptosis. PMID- 29448974 TI - Phyto-oestrogens affect fertilisation and embryo development in vitro in sheep. AB - Phyto-oestrogens such as isoflavones are natural compounds that can profoundly affect reproductive function. In the present study, we tested whether including isoflavone compounds (genistein, biochanin A, formononetin) in the maturation medium would affect the outcomes for ovine oocytes in vitro. Each isoflavone compound was evaluated at five concentrations (0, 2.5, 5, 10, 25ugmL-1) and the entire protocol was repeated four times. Cumulus-oocyte complexes were randomly allocated to the treatments, then fertilised and cultured in vitro. Compared with control (0ugmL-1), the lower concentrations of isoflavone (2.5, 5 and 10ugmL-1) had no detectable effect on the rates of cleavage or embryo development, or on embryo total cell counts (TCC). However, the highest concentration (25ugmL-1) of all three isoflavones exerted a variety of effects (P<0.05): genistein decreased cleavage rate, blastocyst rate and blastocyst efficiency (blastocysts produced per 100 oocytes); biochanin A decreased cleavage rate and blastocyst efficiency; and formononetin decreased blastocyst rate and blastocyst efficiency. Biochanin A (25ugmL-1) reduced embryo TCC specifically at the hatched blastocyst stage (P<0.05). We conclude that the presence of isoflavones at 25ugmL-1 during IVM decreases the cleavage rate and inhibits blastocyst hatching. PMID- 29448975 TI - Analysis of patients with hypomagnesemia using the Japanese Adverse Drug Event Report database (JADER). AB - PURPOSE: In order to clarify the occurrence of hypomagnesemia in Japan, we conducted a database search and analysis using the Japanese Adverse Drug Event Report database (JADER). METHODS: Among the cases recorded in JADER between April 2004 and December 2015, we targeted "hypomagnesemia" and analyzed the patients' backgrounds, drug involvement, other adverse events reported with hypomagnesemia, the time of hypomagnesemia onset, outcomes, and year when reported. For drugs with three or more reports, the signal index was calculated using the Reporting Odds Ratio (ROR) method. In addition, the association between hypomagnesemia onset and other adverse events was investigated using association analysis. RESULTS: The total number of reported hypomagnesemia cases was 201. Males accounted for 62.7%, and patients in their sixties formed a large peak. Three or more cases were reported for 23 causative drugs, among which anti-EGFR antibody, calcineurin inhibitor, platinum antitumor agent and proton pump inhibitor accounted for the majority. ROR analysis detected signals for 18 drugs, and an association was found between hypomagnesemia and other electrolyte abnormalities for those drugs. The median time until onset of hypomagnesemia was classified into three patterns: around 10 days, around 30 days, and longer. Analysis of the report year revealed an increasing tendency in recent years, although increases/decreases were evident depending on fiscal years. CONCLUSION: Our survey was able to reveal the factors associated with the occurrence of hypomagnesemia. PMID- 29448976 TI - In Endothelial Cells, the Activation or Stimulation of Soluble Guanylyl Cyclase Induces the Nitric Oxide Production by a Mechanism Dependent of Nitric Oxide Synthase Activation. AB - PURPOSE: In endothelial cells, investigate if the soluble guanylate cyclase (sGC) activation or stimulation is able to potentiate the relaxation in vessels. METHODS: Aortic and coronary rings with and without endothelium were placed in a myograph and cumulative concentration-effect curves for DETA-NO or ataciguat were performed. Nitric oxide (NO) were measured by fluorescence or by selective electrode in human umbilical endothelial cells (HUVECs) in response to some treatments, including ataciguat, 8-Br-cGMP and A23187. RESULTS: The presence of the endothelium potentiated the relaxation induced by DETA-NO in aortic and coronary rings. In addition, in aortic rings the endothelium potentiated the relaxation induced by ataciguat. In the presence of nitric oxide synthase (NOS) inhibitor, the endothelium effect was abolished to DETA-NO or ataciguat, in both vessels. Ataciguat, 8-Br-cGMP and A23187 were able to induce NO production in HUVECs cells. In the presence of NOS inhibitor, the NO production induced by ataciguat and 8-Br-cGMP was abolished. CONCLUSIONS: Our results suggest that in aortic and coronary rings the endothelium potentiates the relaxation induced by activation or stimulation of sGC through a mechanism dependent of NOS activation.

PMID- 29448978 TI - Effect of Gender on Unplanned Readmissions After Percutaneous Coronary Intervention (from the Nationwide Readmissions Database). AB - Women who undergo percutaneous coronary intervention (PCI) are at higher risk of adverse outcomes compared with men, but it is unknown whether gender affects early unplanned rehospitalization. We analyzed 832,753 patients who underwent PCI from 2013 to 2014 in the Nationwide Readmissions Database. We compared gender differences in incidences, predictors, causes, and cost of unplanned 30-day readmissions and examined the effect of co-morbidity. A total of 832,753 men and women who survived the index PCI and were not admitted for a planned readmission were included in the analysis. Overall, 9.4% of patients had an unplanned readmission within 30 days. Thirty-day readmission rates were higher in women compared with men (11.5% vs 8.4%, p <0.001) even after multivariate adjustment (odds ratio 1.19, 95% confidence interval 1.16 to 1.22, p <0.001), although women had significantly lower costs associated with the readmission ($11,927 vs $12,758, p <0.001). The cause of readmission for women and men were similar and the majority of the readmissions were due to noncardiac causes (58% vs 55%), the most common of which were nonspecific chest pain, gastrointestinal disease, and infections. In contrast, for cardiac readmissions, women are more likely to be readmitted for heart failure (29.64% vs 22.34%), whereas men are more likely to be readmitted for coronary artery disease, including angina (33.47% vs 28.54%). In conclusion, gender disparities exist in rates of unplanned rehospitalization after PCI, where more than 1 in 10 women who undergo PCI are readmitted within 30 days. Gender differences were not observed for causes of noncardiac readmissions, whereas important differences were observed for cardiovascular causes. PMID- 29448979 TI - CD103+CD8+ T lymphocytes in non-small cell lung cancer are phenotypically and functionally primed to respond to PD-1 blockade. AB - CD103+CD8+ tumor infiltrating lymphocytes (TILs) have been linked to prolonged survival in various types of cancer including non-small cell lung cancer (NSCLC). However, the factors associated with the retention of CD103+CD8+ TILs in lung cancer tissues remain largely unknown. Additionally, the contribution of CD103+CD8+ TILs to effective PD-1 based immunotherapy has not been fully elucidated. In this study, we identified that the expression levels of E-cadherin and TGF-beta were significantly correlated with the distribution and the density of CD103+ TILs in lung cancer tumor tissues. Unexpectedly, we observed that CD103+CD8+ TILs that expressed higher levels of PD-1 co-express Ki-67. Moreover, CD103+CD8+ TILs expressed an increased level of T-bet compared to their counterparts, indicating these cells may be better armed for immunotherapy. Lastly, PD-1 pathway blockade led to a significantly increased production of IFN gamma by CD103+CD8+ TILs, suggesting CD103+CD8+ TILs could serve as a predictive biomarker for PD-1 based immunotherapy.

The paediatric conjugate vaccination has resulted in a change in the adult vaccination strategy. The antibiotic resistance of pneumococcus is not currently a severe problem. Nevertheless, the World Health Organisation has included pneumococcus among the bacteria whose treatment requires the introduction of new drugs, such as ceftaroline and ceftobiprole. Although the scientific evidence is still limited, the combination of beta lactams and macrolides is recommended as empiric therapy for bacteraemic pneumococcal pneumonia. PMID- 29448982 TI - Stochastic Gating as a Novel Mechanism for Channel Selectivity. AB - An ideal channel, responsible for metabolite fluxes in and out of the cells and cellular compartments, is supposed to be selective for a particular set of molecules only. However, such a channel has to be wide enough to accommodate relatively large metabolites, and, therefore, it allows passage of smaller solutes, for example, sodium, potassium, and chloride ions, thus compromising membrane's barrier function. Here we show that stochastic gating is able to provide a mechanism for the selectivity of wide channels in favor of large metabolites. Specifically, applying our recent theory of the stochastic gating effect on channel-facilitated transport, we demonstrate that under certain conditions gating hinders translocation of fast-diffusing small solutes to a significantly higher degree than that of large solutes that diffuse much slower. We hypothesize that this can be used by Nature to minimize the shunting effect of wide channels with respect to small solutes.

AB - BACKGROUND/PURPOSE: Hemoglobin monitoring is required in pediatric trauma patients with solid organ injury. We hypothesized that noninvasive hemodynamic monitoring (NIHM) represents an effective, safe alternative to laboratory hemoglobin (LabHb) monitoring in clinically stable patients. METHODS: A retrospective cohort study was conducted regarding pediatric trauma patients (<18 years old) with blunt solid organ injury over six consecutive months. Continuous NIHM was initiated at the time of admission, and LabHb measurements were obtained per institutional guidelines. Measurements were correlated within two hours of assessment and patient outcomes were analyzed. RESULTS: Twenty-one patients met inclusion criteria and had evaluable data. Blunt trauma was the exclusive mechanism of injury, and mean injury severity score was 16.6 for the cohort. Bland Altman analysis showed an average deviation of 0.80 g/dL between NIHM and LabHb values for all data pairs. Measurement trends were highly correlated in patients with stable hemoglobin levels and those requiring blood transfusion. CONCLUSIONS: NIHM demonstrated clinically acceptable accuracy when following hemoglobin trends in the defined pediatric trauma patient population. Slight variances between NIHM and LabHb values were occasionally noted, but did not affect clinical management. Continuous NIHM represents a potentially valuable adjunct to traditional laboratory hemoglobin monitoring. LEVEL OF EVIDENCE RATING: IV. PMID- 29448987 TI - The refeeding syndrome. Importance of phosphorus. AB - Refeeding syndrome (RS) is a complex disease that occurs when nutritional support is initiated after a period of starvation. The hallmark feature is the hypophosphataemia, however other biochemical abnormalities like hypokalaemia, hypomagnesaemia, thiamine deficiency and disorder of sodium and fluid balance are common. The incidence of RS is unknown as no universally accepted definition exists, but it is frequently underdiagnosed. RS is a potentially fatal, but preventable, disorder. The identification of patients at risk is crucial to improve their management. If RS is diagnosed, there is one guideline (NICE 2006) in place to help its treatment (but it is based on low quality of evidence). The aims of this review are: highlight the importance of this problem in malnourished patients, discuss the pathophysiology and clinical characteristics, with a final series of recommendations to reduce the risk of the syndrome and facilitate the treatment. PMID- 29448988 TI - Public awareness and knowledge of stuttering in Japan. AB - PURPOSE: To determine laypeople's knowledge and awareness of stuttering in Japan. METHODS: A total of 303 respondents, recruited by street sampling, completed a questionnaire assessing the prevalence, onset, gender distribution, occurrence in different races, cause, treatment, association with intelligence, and hereditariness of stuttering. The questionnaire used was a Japanese version of that devised by Van Borsel, Verniers, and Bouvry (1999) for use in Belgium. RESULTS: Although around half of the respondents had heard or met a stutterer, they tended to misunderstand the stuttering; e.g., respondents estimated the prevalence of stuttering as high. Knowledge also differed according to age, gender, and education level. Specifically, older individuals, females, and individuals with higher levels of education tended to have greater knowledge of stuttering. In comparing the results of the present study with similar studies conducted in Belgium, China, and Brazil, we observed several similarities and differences. DISCUSSION: Although most respondents were to some extent familiar with stuttering, their overall knowledge of the condition was limited. Certain factors could be involved in having knowledge of stuttering, such as one's life experience, cultural background, and social attitudes toward stuttering. The findings suggest the need for growing knowledge and awareness of stuttering.

AB - Enterocutaneous fistulae (ECF) and enteroatmospheric fistulae (EAF) are difficult complications that primarily arise after abdominal surgical procedures. Development of an ECF or EAF carries significant mortality and morbidity. Effective management of patients with these disease states requires a multidisciplinary approach, which includes surgical, pharmacotherapeutic, and nutritional interventions. This review focuses on the medical and nutritional management of ECF/EAF, providing background on drug agents and nutritional strategies that may be helpful in reducing effluent volume, optimizing fistula healing, and maintaining nutritional health. PMID- 29448990 TI - Open abdomen in liver transplantation. AB - INTRODUCTION: Damage control laparotomy with vacuum assisted closure (VAC) is used for selective cases in trauma. In liver transplantation, VAC has also been applied for management of intra-operative hemorrhage. The primary objective was to evaluate peri-operative blood loss and blood product utilization in VAC compared to primary abdominal closure (PAC) at the index transplant operation. METHODS: Retrospective review of all adults undergoing deceased donor liver transplantation (2007-2011) at a single center tertiary care institution. RESULTS: 201 deceased donor liver transplantations were performed, with 167 PAC and 34 VAC cases. Intra-operative blood loss (4.4L vs 10.7L), cell saver return (1399 ml vs 3998 ml), FFP (7.6U vs 15.9U) and PLT requirements (8.5U vs 18.3U), were all significantly elevated in VAC compared to PAC. VAC patients had significantly increased RBC, FFP, PLT, and total volume requirements during initial ICU admission. 30 PAC cases required on demand laparotomy and most commonly for post-operative bleeding. CONCLUSION: In liver transplantation, application of VAC secondary to massive intra-operative exsanguination was safely utilized. Further evaluation is required to identify long-term morbidity and mortality.

AB - AIMS: The aim of this retrospective review was to identify all children that presented to our institution with a pelvic or acetabular fracture and to compare these children to a previous cohort of paediatric pelvic fractures that we have reported. PATIENTS: 53 children under the age of 16 were identified over a ten year period. METHODS: We reviewed our trauma database, hospital records and radiological imaging to determine the age, gender, fracture pattern, associated injuries and management of the pelvic fracture. RESULTS: There were 32 boys and 21 girls. Mean age of the boys was 8.8 years and the girls 10.7 years. In seven children the pelvic fracture was an isolated injury and in the remaining 46 children, there were 113 additional injuries. 56% of the additional injuries was either a fracture/dislocation (37%) or a head injury (19%). Compared to our first cohort, we had a larger number of children in the second cohort. Age, sex distribution, mechanism of injury was similar in the two groups. In this current cohort, use of CT scan imaging was more frequent, there were more unstable pelvic fracture patterns identified, ISS scores were higher and mortality was lower. CONCLUSION: We have seen more children with more severe injuries, higher ISS scores but a lower mortality rate.

AB - INTRODUCTION: Adjacent level spondylodiscitis (ALS) after primary surgery for thoracic spondylodiscitis is a very rare condition. CASE REPORT: We report the case of a 76-year-old man with this pathology. A first posterior minimally invasive approach combined with anterior approach to the thoracic spine was safely performed for thoracic spondylodiscitis. More than a year later, exploration of recurrent symptoms with 18FDG PET scan helped to diagnose ALS. Further surgery was performed. At 3-year follow-up examination showed no recurrence of the infection. DISCUSSION: ALS should be suspected during recurrent symptoms after spinal fusion surgery. Evaluation should be based on the results of 18FDG PET scan and surgery. CONCLUSION: Bacterial and histopathological analyses combined with an increase of spine fixation and adapted antimicrobial therapy are a safe management for ALS. PMID- 29448994 TI - Automatic untargeted metabolic profiling analysis coupled with Chemometrics for improving metabolite identification quality to enhance geographical origin discrimination capability. AB - Untargeted metabolic profiling analysis is employed to screen metabolites for specific purposes, such as geographical origin discrimination. However, the data analysis remains a challenging task. In this work, a new automatic untargeted metabolic profiling analysis coupled with a chemometric strategy was developed to improve the metabolite identification results and to enhance the geographical origin discrimination capability. Automatic untargeted metabolic profiling analysis with chemometrics (AuMPAC) was used to screen the total ion chromatographic (TIC) peaks that showed significant differences among the various geographical regions. Then, a chemometric peak resolution strategy is employed for the screened TIC peaks. The retrieved components were further analyzed using ANOVA, and those that showed significant differences were used to build a geographical origin discrimination model by using two-way encoding partial least squares. To demonstrate its performance, a geographical origin discrimination of flaxseed samples from six geographical regions in China was conducted, and 18 TIC peaks were screened. A total of 19 significant different metabolites were obtained after the peak resolution. The accuracy of the geographical origin discrimination was up to 98%. A comparison of the AuMPAC, AMDIS, and XCMS indicated that AuMPACobtained the best geographical origin discrimination results. In conclusion, AuMPAC provided another method for data analysis. PMID- 29448995 TI - A stochastic view on column efficiency. AB - A stochastic model of transcolumn eddy dispersion along packed beds was derived. It was based on the calculation of the mean travel time of a single analyte molecule from one radial position to another. The exchange mechanism between two radial positions was governed by the transverse dispersion of the analyte across the column. The radial velocity distribution was obtained by flow simulations in a focused-ion-beam scanning electron microscopy (FIB-SEM) based 3D reconstruction from a 2.1 mm * 50 mm column packed with 2 MUm BEH-C18 particles. Accordingly, the packed bed was divided into three coaxial and uniform zones: (1) a 1.4 particle diameter wide, ordered, and loose packing at the column wall (velocity uw), (2) an intermediate 130 MUm wide, random, and dense packing (velocity ui), and (3) the bulk packing in the center of the column (velocity uc). First, the validity of this proposed stochastic model was tested by adjusting the predicted to the observed reduced van Deemter plots of a 2.1 mm * 50 mm column packed with 2 MUm BEH-C18 fully porous particles (FPPs). An excellent agreement was found for ui = 0.93uc, a result fully consistent with the FIB-SEM observation (ui = 0.95uc). Next, the model was used to measure ui = 0.94uc for 2.1 mm * 100 mm column packed with 1.6 MUm Cortecs-C18 superficially porous particles (SPPs). The relative velocity bias across columns packed with SPPs is then barely smaller than that observed in columns packed with FPPs (+6% versus + 7%). uw=1.8ui is measured for a 75 MUm * 1 m capillary column packed with 2 MUm BEH-C18 particles. Despite this large wall-to-center velocity bias (+80%), the presence of the thin and ordered wall packing layer has no negative impact on the kinetic performance of capillary columns. Finally, the stochastic model of long-range eddy dispersion explains why analytical (2.1-4.6 mm i.d.) and capillary (<400 MUm i.d.) columns can all be packed efficiently (1 3) with sub-2 MUm particles and with 1 MUm particles, respectively.

PMID- 29448996 TI - Automating data analysis for two-dimensional gas chromatography/time-of-flight mass spectrometry non-targeted analysis of comparative samples. AB - Non-targeted analysis of environmental samples, using comprehensive two dimensional gas chromatography coupled with time-of-flight mass spectrometry (GC * GC/ToF-MS), poses significant data analysis challenges due to the large number of possible analytes. Non-targeted data analysis of complex mixtures is prone to human bias and is laborious, particularly for comparative environmental samples such as contaminated soil pre- and post-bioremediation. To address this research bottleneck, we developed OCTpy, a PythonTM script that acts as a data reduction filter to automate GC * GC/ToF-MS data analysis from LECO(r) ChromaTOF(r) software and facilitates selection of analytes of interest based on peak area comparison between comparative samples. We used data from polycyclic aromatic hydrocarbon (PAH) contaminated soil, pre- and post-bioremediation, to assess the effectiveness of OCTpy in facilitating the selection of analytes that have formed or degraded following treatment. Using datasets from the soil extracts pre- and post-bioremediation, OCTpy selected, on average, 18% of the initial suggested analytes generated by the LECO(r) ChromaTOF(r) software Statistical Compare feature. Based on this list, 63-100% of the candidate analytes identified by a highly trained individual were also selected by OCTpy. This process was accomplished in several minutes per sample, whereas manual data analysis took several hours per sample. OCTpy automates the analysis of complex mixtures of comparative samples, reduces the potential for human error during heavy data handling and decreases data analysis time by at least tenfold. PMID- 29448998 TI - Cardiac amyloidosis: from clinical suspicion to morphological diagnosis. AB - Amyloidosis is a heterogeneous group of diseases characterised by extracellular accumulation of amyloid in various tissues and organs of the body, leading to alteration and destruction of tissues. Heart involvement is the most important prognostic factor in patients with systemic amyloidosis and the diagnosis and typing of amyloid must be made properly. The clinical picture shows congestive heart failure with predominant right-sided heart failure symptoms in fully developed disease, various types of arrhythmias and characteristic electrocardiography and echocardiography findings. Blood and urine monoclonal protein studies and cardiac biomarkers belong to the spectrum of standard laboratory examinations. Cardiac cardiomyopathy is connected with amyloid based on immunoglobulin light chains, serum amyloid A, transthyretin, atrial natriuretic factor or apolipoprotein A1. In the routine diagnostic algorithm, biopsy specimens are examined using special histological staining, immunohistochemistry and immunofluorescence; proteomic analysis is only performed in specialised centres. PMID- 29448999 TI - Quantitative perineural invasion is a prognostic marker in prostate cancer. AB - This study aimed to investigate the prognostic value of a quantitative, detailed, yet practical analysis of perineural invasion in radical prostatectomy specimens in a high-risk prostate cancer cohort. A total of 114 patients with prostate cancer who underwent radical prostatectomy between 2000 and 2013 were analysed. Using S100 protein immunohistochemistry assisted in the detection of nerves. In the area of closest proximity of the tumour to the dorso-lateral margins, nerves were counted and the infiltration of nerves was categorised (0-3). Category 0 was nerves without immediate tumour-cell-contact. All nerves being fully surrounded by tumour (classical perineural carcinosis) were categorised group 3. Two further categories discriminated between nerves that were touched either by carcinoma cells below 50% of the circumference (category 1) or above (category 2). Perineural carcinosis (Pn1) was seen in 61.4% of cases and correlated positively with ISUP grades, pT categories and presence of intraductal carcinoma but failed significance on Kaplan-Meier analysis. A more quantitative analysis of percentual perineural involvement did demonstrate significant survival differences: cases with less than one Pn1-positive nerve in 5 high power fields had longer survival times. Incomplete perineural involvement (category 1-2) did not have a prognostic value, endorsing the current definition of perineural carcinosis as full circumferential encasement of a nerve by tumour cells. A quantitative analysis of the percentage of nerves positive for perineural invasion has a higher prognostic value than the classical dichotomous statement on the mere presence of perineural invasion. PMID- 29449000 TI - An immunohistochemical and molecular analysis of papillary proliferation of the endometrium. AB - Papillary proliferations of the endometrium (PPEs) are uncommon lesions that are often associated with endometrial polyps. PPEs occasionally precede or co-exist with atypical endometrial hyperplasia or adenocarcinoma, but their pathogenesis and relationship to endometrial neoplasia is uncertain. In the present study 11 PPEs, including eight benign papillary proliferations (BPPs) and three complex papillary hyperplasias (CPHs) were examined immunohistochemically for expression of PAX2, BAF250a, p16, beta-catenin and DNA mismatch repair (MMR) proteins. Molecular analysis was also performed on the CPHs using targeted next generation sequencing (NGS). All PPEs demonstrated at least one immunohistochemical abnormality with altered expression of p16 and PAX2 in nine and seven cases, respectively, and beta-catenin in one case. However, none of the cases showed loss of BAF250a or MMR protein staining. All CPHs showed KRAS mutations with additional mutations in AKT1 and FBXW7 in one case each, and both PIK3CA and CTNNB1 in the remaining case. Therefore, PPEs demonstrate immunophenotypical and molecular overlap with endometrial endometrioid neoplasia, although loss of BAF250a and MMR protein function do not appear to contribute significantly to these lesions. KRAS mutations may be important drivers in CPHs but this finding needs to be confirmed in larger studies. PMID- 29449001 TI - Balance assessment during squatting exercise: A comparison between laboratory grade force plate and a commercial, low-cost device. AB - Testing balance through squatting exercise is a central part of many rehabilitation programs and sports and plays also an important role in clinical evaluation of residual motor ability. The assessment of center of pressure (CoP) displacement and its parametrization is commonly used to describe and analyze squat movement and the laboratory-grade force plates (FP) are the gold standard for measuring balance performances from a dynamic view-point. However, the Nintendo Wii Balance Board (NWBB) has been recently proposed as an inexpensive and easily available device for measuring ground reaction force and CoP displacement in standing balance tasks. Thus, this study aimed to compare the NWBB-CoP data with those obtained from a laboratory FP during a dynamic motor task, such as the squat task. CoP data of forty-eight subjects were acquired simultaneously from a NWBB and a FP and the analyses were performed over the descending squatting phase. Outcomes showed a very high correlation (r) and limited root-mean-square differences between CoP trajectories in anterior posterior (r > 0.99, 1.63 +/- 1.27 mm) and medial-lateral (r > 0.98, 1.01 +/- 0.75 mm) direction. Spatial parameters computed from CoP displacement and ground reaction force peak presented fixed biases between NWBB and FP. Errors showed a high consistency (standard deviation < 2.4% of the FP outcomes) and a random spread distribution around the mean difference. Mean velocity is the only parameter which exhibited a tendency towards proportional values. Findings of this study suggested the NWBB as a valid device for the assessment and parametrization of CoP displacement during squatting movement. PMID- 29449002 TI - Shoulder joint kinetics and dynamics during underwater forward arm elevation. AB - Aquatic exercises are widely implemented into rehabilitation programs. However, both evaluating their mechanical demands on the musculoskeletal system and designing protocols to provide progressive loading are difficult tasks. This study reports for the first time shoulder joint kinetics and dynamics during underwater forward arm elevation performed at speeds ranging from 22.5 to 90 degrees /s. Net joint moments projected onto anatomical axes of rotation, joint power, and joint work were calculated in 18 participants through a novel approach coupling numerical fluid flow simulations and inverse dynamics. Joint dynamics was revealed from the 3D angle between the joint moment and angular velocity vectors, identifying three main functions-propulsion, stabilization, and resistance. Speeds <30 degrees /s necessitated little to no power at all, whereas peaks about 0.20 W?kg-1 were seen at 90 degrees /s. As speed increased, peak moments were up to 61 * higher at 90 than at 22.5 degrees /s, (1.82 +/- 0.12%BW?AL vs 0.03 +/- 0.01%BW?AL, P < 0.038). This was done at the expense of a substantial decrease in the joint moment contribution to joint stability though, which goes against the intuition that greater stabilization is required to protect the shoulder from increasing loads. Slow arm elevations (<30 degrees /s) are advantageous for joint mobility gain at low mechanical solicitation, whereas the intensity at 90 degrees /s is high enough to stimulate muscular endurance improvements. Simple predictive equations of shoulder mechanical loading are provided. They allow for easy design of progressive protocols, either for the postoperative shoulder or the conditioning of athlete targeting very specific intensity regions. PMID- 29449003 TI - Upper partial fibulectomy improves knee biomechanics and function and decreases knee pain of osteoarthritis: A pilot and biomechanical study. AB - To investigate the change in clinical outcomes and biomechanical properties of the knee in response to upper partial fibulectomy. Sixteen patients with medial compartment knee osteoarthritis (KOA) underwent upper partial fibulectomy. Visual analog scale (VAS) pain, the hospital for special surgery knee score (HSS), hip knee-ankle (HKA) angle (measured in the frontal plane), and flexion/extension range of motion of the knee were assessed before and up to 6 months after surgery. Patients were evaluated for gait parameters and overall peak knee adduction moment (KAM). Patient-specific finite element knee models were developed to investigate changes in load in response to fibulectomy. Both VAS pain and HSS score were significantly improved (P < .001) one day after surgery and steadily improved during the subsequent 6 months. HKA angle improved (P = .006) immediately and remained stable by 3 months after surgery. A significant inverse relationship (R = -0.528, P = .012) between the overall peak KAM (decreased by 19.1%) and the HKA (increased by 1.24 degrees from a more varus to more neutral alignment) angle was observed. The minor load supported by the fibula preoperatively was spread post-operatively over the cortical bone of the tibial shaft. The mean stress in the medial tibial plateau was significantly decreased (P < .001), with a portion of the stress transferred to the posterior lateral region of the tibial plateau after upper partial fibulectomy. This pilot study provides objective 3D gait and plausible biomechanical evidence for the improvement in clinical symptoms from partial upper fibulectomy. PMID- 29449004 TI - Reply. PMID- 29449005 TI - Association between Oxidative Stress, Genetic Factors, and Clinical Severity in Children with Sickle Cell Anemia. AB - OBJECTIVES: To investigate the associations between several sickle cell disease genetic modifiers (beta-globin haplotypes, alpha-thalassemia, and glucose-6 phosphate dehydrogenase deficiency) and the level of oxidative stress and to evaluate the association between oxidative stress and the rates of vaso-occlusive events. STUDY DESIGN: Steady-state oxidative and nitrosative stress markers, biological variables, genetic modulators, and vaso-occlusive crisis events requiring emergency admissions were measured during a 2-year period in 62 children with sickle cell anemia (58 SS and 4 Sbeta0). Twelve ethnic-matched children without sickle cell anemia also participated as healthy controls (AA) for oxidative and nitrosative stress level measurement. RESULTS: Oxidative and nitrosative stress were greater in patients with sickle cell anemia compared with control patients, but the rate of vaso-occlusive crisis events in sickle cell anemia was not associated with the level of oxidative stress. The presence of alpha-thalassemia, but not glucose-6-phosphate dehydrogenase deficiency or beta globin haplotype, modulated the level of oxidative stress in children with sickle cell anemia. CONCLUSION: Mild hemolysis in children with alpha-thalassemia may limit oxidative stress and could explain the protective role of alpha-thalassemia in hemolysis-related sickle cell complications.

PMID- 29449008 TI - Tardive dyskinesia: Out of the shadows. AB - The approvals of the first two medications, valbenazine and deutetrabenazine, to treat tardive dyskinesia have ushered in a new era in neuropsychiatric care. Tardive syndromes are defined as delayed onset, persistent movement disorders or sensory phenomena that occur in association with exposure to dopamine receptor blocking agents (DRBAs). Their underlying pathophysiology remains to be fully elucidated, but clinicians can conceptualize tardive syndromes as persistent dopamine supersensitivity states. Tardive syndromes can potentially cause distress, disfigurement, embarrassment, and dysfunction, and are often permanent. Therefore, practitioners who prescribe DRBAs should be aware of this potential, carefully assess the risk/benefit ratio when considering the use of these medications, and be sure that patients are appropriately informed. Patients on DRBAs should be monitored for the development of tardive syndromes, including through the use of regularly scheduled Abnormal Involuntary Movement Scale (AIMS) (or similar) examinations. Clinicians prescribing DRBAs should be familiar with the diagnosis and management of tardive syndromes, and be able to institute treatment or refer patients when treatment is appropriate. Future research may focus on the potential benefit of earlier introduction of VMAT2 inhibitors to delay onset or progression of tardive syndromes. More effective treatments are still needed, as are effective, well-tolerated antipsychotics that do not cause tardive syndromes.

AB - Plexiform neurofibroma (PNF) is a rare variant of neurofibromatosis type1 (NF-1), which histopathologically, is a subtype of benign nerve sheath tumors, neurofibromas (NF). It develops as a result of proliferation in all parts of peripheral nervous system and can cause the functional damage, deformities, pain, considerable mortality, and morbidity and even the increasing risk of malignant transformation in some critical cases. Currently, the surgical intervention is the treatment of choice for PNF patients, which due to the tumor invasion, massive growth, and the chance of postoperative regrowth is not possible. The diagnosis of isolated tumor is an uncommon event. Considering the rarity of this neoplasm, herein, we describe a case of isolated PNF, so the purpose of this presenting is the rarity of recording. We describe a case of isolated plexiform neurofibroma presented with 7-year history of a slowly growing postauricular soft subcutaneous mass in a 14-year-old boy, which caused the right auricular deformity. After initial evaluation by imaging studies, the patient underwent to surgical resection of the mass and the diagnosis of plexiform neurofibroma was confirmed by histopathologic examination. Surgical excision of the mass had been done before which concluded the satisfactory result and based on oncologist diagnosis, further intervention such as radiotherapy or chemotherapy was not needed. The patient left the hospital with a clinical stability and was suggested to continue the regular follow-up. In conclusion, considering neurofibroma (NF) as differential diagnosis for subcutaneous masses in head and neck area is critical for early diagnosis and treatment procedure.

PMID- 29449015 TI - Rapid initiation of guided bone regeneration driven by spatiotemporal delivery of IL-8 and BMP-2 from hierarchical MBG-based scaffold. AB - Initiation of endogenous repair mechanisms, including key steps of stem cell recruitment and cartilage intermediate formation in endochondral ossification, is vital to regeneration of large bone defects. To biomimetically promote a rapid initiation and ensuing osteogenic stimulation, exogenous chemokine IL-8 and growth factor BMP-2 were orchestrated in a mesoporous bioactive glass (MBG)-based spatiotemporal delivery system, to achieve a rapid release of IL-8 followed by a long-term sustained release of BMP-2. The synergistic effect of IL-8 and BMP-2 on initiation stage of bone healing and underlying mechanism were thoroughly investigated in vitro and in vivo. Intriguingly, apart from its superiority in stem cell recruitment to BMP-2, IL-8 not only endowed a histological "prep-state" of endochondral ossification by up-regulating chondrogenic genes and inducing the formation of extensive cartilage tissues, facilitating rapid bone transformation by BMP-2, but also triggered a cellular "prep-state" with high expression of BMP receptors, enhancing the osteoinductivity of BMP-2. With the spatiotemporal delivery system, orchestrated signal stimuli of IL-8 and BMP-2 induced a rapid initiation including efficient stem cell recruitment and a "chondrogenic/osteogenic balance" at the first stage of endochondral ossification, and the scaffold facilitated sufficient osteoconductivity, together resulting in early extensive bone mineralization and an advanced regeneration throughout the repair of large bone defect. We believe this new idea could provide insights toward designing bone-repairing biomaterials with higher regenerative efficiency. PMID- 29449014 TI - Periarticular bone predicts knee osteoarthritis progression: Data from the Osteoarthritis Initiative. AB - OBJECTIVE: Osteoarthritis (OA) is a disease with a substantial public health burden. Quantitative assessments of periarticular bone may be a biomarker capable of monitoring early disease progression. The purpose of this study was to evaluate whether measures of periarticular bone associate with longitudinal structural progression. METHODS: We conducted a 12-18 months longitudinal study using the Osteoarthritis Initiative (OAI). Participants received knee dual-energy x-ray absorptiometry (DXA), trabecular magnetic resonance (MR) imaging, and x rays. Knee DXAs generated proximal tibial medial:lateral periarticular bone mineral density (paBMD) measures. Proximal tibial trabecular MR images were assessed for trabecular morphometry: apparent bone volume fraction (BVF), trabecular number, thickness, and spacing. Weight-bearing x-rays were assessed for medial tibiofemoral joint space narrowing (JSN). Chi-squared analyses assessed whether periarticular bone measures were predictive of worsening medial tibiofemoral JSN, adjusted for age, sex, and BMI. RESULTS: In all, 444 participants, mean age 64.2 +/- 9.2 years, BMI 29.5 +/- 4.6kg/m2, and 52% male at baseline. Medial JSN (radiographic progression) occurred in 40 participants (9%). Higher baseline medial:lateral paBMD, apparent BVF, trabecular number and thickness, and lower baseline and decreased trabecular spacing were all associated with more progression of JSN in the medial compartment. From lowest to highest baseline medial:lateral paBMD quartile groups, 2%, 5%, 11%, and 18% had medial JSN progression, respectively, between the 36- and 48-month visits, p values = 0.001 and 0.002 unadjusted and adjusted. The rate of change in medial:lateral paBMD, apparent BVF, and spacing were associated with more medial JSN. For rate of medial:lateral paBMD change from lowest to highest quartile, the proportion of each group that experienced medial JSN progression were 5%, 5%, 11%, and 18%, with an unadjusted and adjusted p-value of 0.005. CONCLUSION: Baseline and most rates of periarticular bone change associate with knee OA structural progression, highlighting the close relationship between subchondral bone and JSN. Future studies should focus on developing these measures as predictive and pathophysiological biomarkers, and evaluating their deployment in clinical trials testing bone-targeted therapeutics. PMID- 29449016 TI - Redox-dependent axial ligand replacement and its functional significance in heme bound iron regulatory proteins. AB - Iron regulatory proteins (IRPs), regulators of iron metabolism in mammalian cells, control the translation of proteins involved in iron uptake, storage and utilization by binding to specific iron-responsive element (IRE) sequences of mRNAs. Two homologs of IRPs (IRP1 and IRP2) have a typical heme regulatory motif (HRM), a consensus sequence found in "heme-regulated proteins". However, specific heme binding to HRM has been reported only for IRP2, which is essential for oxidative modification and loss of binding to target mRNAs. In this paper, we confirmed that IRP1 also specifically binds two molar equivalents of heme, and found that the absorption and resonance Raman spectra of heme-bound IRP1 were quite similar to those of heme-bound IRP2. This shows that the heme environmental structures in IRP1 are close to those of proteins using heme as a regulatory molecule. Pulse radiolysis experiments, however, clearly revealed an axial ligand exchange from Cys to His immediately after the reduction of the heme iron to form a 5-coordinate His-ligated heme in heme-bound IRP2, whereas the 5-coordinate His ligated heme was not observed after the reduction of heme-bound IRP1. Considering that the oxidative modification is only observed in heme-bound IRP2, but not IRP1, probably owing to the structural flexibility of IRP2, we propose that the transient 5-coordinate His-ligated heme is a prerequisite for oxidative modification of heme-bound IRP2, which functionally differentiates heme binding of IRP2 from that of IRP1.

Hearing aids remain the treatment of choice, but, unfortunately, even state-of-the-art devices provide only limited benefit for the perception of speech in noisy environments. While traditionally viewed primarily as a loss of sensitivity, hearing loss is also known to cause complex distortions of sound-evoked neural activity that cannot be corrected by amplification alone. This Opinion article describes the effects of hearing loss on neural activity to illustrate the reasons why current hearing aids are insufficient and to motivate the use of new technologies to explore directions for improving the next generation of devices.

AB - OBJECTIVES: This study investigated the effect of matrix metalloproteinase 8 (MMP 8) on resin-dentin bonds, assessed the mechanical properties of the interfaces over time, and discussed the potential application of MMP-8 inhibitor I (MMP8-I) as a specific MMP-8 inhibitor to be incorporated into dental adhesives. METHODS: The activation and inhibition of MMP-8 was detected by colorimetric assay. After 1 day, 6 months and 1 year of storage of Control, MMP8-I, and chlorhexidine (CHX) groups, the microtensile bond strengths (MUTBS) were used to evaluate the bond strength and failure mode distributions, and nanoleakage analysis was used to evaluate the minor scattered silver particles. RESULTS: Colorimetric assay showed that the activated MMP-8 was enhanced by adhesive procedures, while it was inhibited by the additional treatment of MMP8-I or CHX. Compared with the Control and CHX groups, the MMP8-I group had significantly higher bond strength and the hybrid layer from the MMP8-I-treated dentin exhibited structural integrity of the collagen network and decreased silver nitrate penetration after 1 year of storage. SIGNIFICANCE: MMP-8 inhibition I protects against the degradation of resin-dentin bonds over time, which is better than broad-scale enzyme inhibitor CHX. It shows that MMP8-I may be used in dentistry for preventing collagen degradation within hybrid layers to extend the longevity of resin-dentin bonds. PMID- 29449022 TI - Expression patterns of claudin-5 and its related signals during luteal regression in pseudopregnant rats: The enhanced effect of additional PGF treatment. AB - To study the expression patterns of claudin-5 and its related signals during luteal regression in rats, a sequential PMSG/hCG treatment paradigm was used to obtain a single, well-defined generation of corpus luteum (CL). A total of 35 rats were treated with one PGF or two PGF at an interval of 24 h from day 7 of pseudopregnancy to induce CL regression. Serum and ovaries were collected at 0, 2, 4, 8 or 24 h after one PGF injection (1 PGF), 2 or 24 h after two PGF injections (2 PGF). The serum progesterone level was detected by RIA; the ovarian expression of claudin-5, the phosphorylations of STAT3 (p-STAT3), Akt (p-Akt), ERK1/2 (p-ERK) and p38 MAPK (p-p38) were detected by western blot, real-time PCR and IHC. Results showed that serum progesterone (P4) decreased after PGF treatment. Claudin-5 mRNA decreased at 4 h and 8 h after 1 PGF and 2 h after 2 PGF, and claudin-5 protein decreased at 4 h after 1 PGF. p-STAT3 increased at 4 h after 1 PGF and 2 h after 2 PGF. p-ERK increased at 2 h after 2 PGF. The level of p-Akt decreased at 4 h after 1 PGF. PGF treatment did not alter the phosphorylation of p38 MAPK at any time points in this study. IHC results revealed that claudin-5 was expressed in the nuclei and cytoplasm of steroidogenic cells and in the vessels, while PGF induced-p-STAT3 was expressed uniformly in the cytoplasm of luteal steroidogenic cells. In conclusion, PGF treatment decreased the expression of claudin-5 and the additional PGF treatment enhanced the decrease in claudin-5 mRNA expression and the increases in ERK1/2 and STAT3 phosphorylation in the corpus luteum of pseudopregnant rats, which will contribute new information to the further study of molecular mechanism of luteal regression.

PMID- 29449024 TI - Surrogate Alcohol or Nonbeverage Alcohol Consumption: The Surrogate Alcohol Questionnaire (SAQ). AB - BACKGROUND: Diagnosis and treatment of alcohol use disorders and their sequelae are common clinical questions for the consultation-liaison psychiatrist. At an urban, academic medical center, the authors consulted on several patients whose consumption of alcohol included nonbeverage forms of alcohol, (described in the literature as surrogate alcohols, nonbeverage alcohols, e.g., mouthwash). METHODS: The authors describe 4 patients who presented with surrogate alcohol consumption. The authors review the clinical issues and literature related to surrogate alcohol use. The authors describe the array of substances, which either contain ethanol, but are not intended for drinking, or which contain other intoxicating alcohols (e.g., methanol), that are consumed in lieu of traditional beverage alcohol. Furthermore, the authors discuss standard medical treatment interventions for ethanol and non-ethanol based alcohols. The authors propose a screening tool, the surrogate alcohol questionnaire, a tool to facilitate better recognition of surrogate alcohol use. PMID- 29449025 TI - [Prospective, monocentric, uncontrolled study of efficacy, tolerance and adherence of cyclosporin 0.1 % for severe dry eye syndrome]. AB - PURPOSE: To evaluate the efficacy, tolerability and treatment adherence of Ikervis(r) (Santen, SAS) (ciclosporine 0.1 %) for first line therapy or following treatment with Restasis(r) (Allergan, Inc.) (ciclosporine 0.05 %) for severe dry eye syndrome. MATERIAL AND METHODS: A prospective, monocentric, uncontrolled study was conducted between January 2012 and March 2015 on 110 eyes of 55 patients with severe dry eye on first line therapy or previously treated with Restasis(r) who required the introduction of Ikervis(r). Patients' quality of life was assessed before and after treatment was started using a standardized questionnaire (Ocular Surface Disease Index(c) [OSDI]), clinical efficacy was quantified at the slit lamp, by measurement of the Break Up time Test (BUT) and the Oxford classification. Tolerability and adherence to treatment were measured using a simple questionnaire. RESULTS: A total of 72 eyes of 37 patients were included. Etiologies of dry eye syndrome were dominated by Sjogren syndrome (32 %) and severe ocular surface conditions (48 %). The mean age was 57.7 years (+/ 17.45) and mean follow-up was 458 days (+/-292). The mean BUT increased by 2.043seconds [1.522-2.563] (P<0.0001). Corneal/conjunctival involvement evaluated by the Oxford classification was also improved with a difference in level of 1.68 [1.290-2.071] (P<0.0001). Ocular Surface Disease Index(c) (OSDI) decreased by 21.7 [16.372-27.024] (P<0.0001). Treatment tolerability was moderate, with more than 50 % of patients experiencing pain on instillation. Overall satisfaction with treatment was good, with more than 60 % of patients feeling better after initiation of treatment. CONCLUSION: Ikervis(r) is an effective treatment of severe dry eye. Its indications tend to evolve towards less severe dry eye. However, the tolerability profile remains poor, and an improvement in this would be desirable. PMID- 29449026 TI - Validity of a single PTSD checklist item to screen for insomnia in survivors of critical illness. AB - BACKGROUND: There is no insomnia screening tool validated in intensive care unit (ICU) survivors. OBJECTIVES: To examine the validity of a single item from the PTSD checklist-Civilian version (PCL-C) to detect insomnia by Insomnia Severity Index (ISI) METHODS: We performed a secondary analysis of data from a longitudinal investigation in 120 medical-surgical ICU survivors. At 1 year post ICU, patients completed ISI, PCL-C, and Medical Short-Form 12 (SF-12) by telephone. A single PCL-C item rates difficulty initiating or maintaining sleep over the past month. We compared performance characteristics of this PCL-C item to ISI-defined insomnia (ISI >=15). RESULTS: A score of >=3 on the PCL-C sleep item exhibited 91% sensitivity and 67% specificity for ISI-defined insomnia (ISI >= 15), and it demonstrated construct validity by correlation to related QOL indices. CONCLUSIONS: A single PCL-C sleep item score >= 3 is a reasonable screen to identify insomnia symptoms in ICU survivors.

Roots are the plant organs that take up the major part of water, from the surrounding soil. Water uptake is related to the root system architecture, root growth, age and species dependent complex developmental changes in the anatomical structures. The latter is mainly attributed to the deposition of suberized barriers in certain layers of cell walls, such as endo- and exodermis. With respect to water permeability, changes in the suberization of roots are most relevant. Water transport or hydraulic conductivity of roots (Lpr) can be described by the composite transport model and is known to be very variable between plant species and growth conditions and root developmental states. In this review, we summarize how anatomical structures and apoplastic barriers of roots can diversely affect water transport, comparing the model plant Arabidopsis with crop plants, such as barley and rice. Results comparing the suberin amounts and water transport properties indicate that the common assumption that suberin amount negatively correlates with water and solute transport through roots may not always be true. The composition, microstructure and localization of suberin may also have a great impact on the formation of efficient barriers to water and solutes. PMID- 29449029 TI - Development of alcohol expectancies and early alcohol use in children and adolescents: A systematic review. AB - PURPOSE: Developmental changes in alcohol expectancies (AE) have been proposed to lead to alcohol use initiation and later alcohol use in adolescence. This systematic review aims to provide longitudinal evidence of the development of AE and the relation of AE to alcohol outcomes from childhood to late adolescence (4 18 years old). METHODS: A computer-assisted search of relevant articles identified 1602 studies, of which 43 studies (conducted between 1996 and 2016) were selected. RESULTS: First, negative AE decline and positive AE increase in early adolescence. Moreover, alcohol use (initiation) seems to strongly influence changes in AE. Second, AE predict alcohol use initiation and drinking patterns over time. Third, longitudinal predictors of AE could be divided into individual predictors (i.e., alcohol-related cognitions, psychopathology, and genetics) and environmental predictors (i.e., family, peer, and media influences). Lastly, the results indicated that AE function as mediators of the relations between the various individual and environmental predictors and adolescent's alcohol use. CONCLUSIONS: Alcohol expectancies form an important framework through which drinking behavior can be explained over time. Due to the diverse findings on the predictors of AE, future longitudinal studies should further clarify the factors that are essential in the development of AE and adolescent's later alcohol use.

In recent years, biological resource centres (BRCs) have developed in such a way that they provide all activities relating to the handling of samples. In this context, France is undoubtedly a pioneering country, because most of the biological collections available were created on the basis of themed research projects, which involved a particular donor phenotype. The round table was an opportunity to emphasise the persistence of some pitfalls particularly in relation to ensuring the consistency of different regulatory pathways. It also gave the opportunity to question and make recommendations on aspects of governance of biological collections and the BRCs, to state the challenges linked to scientific and economic valorisation and to consider the place of patients and the general public. The development of specific education in public health and research is essential to underline that these initiatives are necessary for developing new diagnostic and therapeutic procedures.

AB - G4C2 hexanucleotide repeat expansions in the C9orf72 gene seem to be the cause of numerous cases of amyotrophic lateral sclerosis (ALS) and/or frontotemporal dementia (FTD). In this study, we investigated the presence of the G4C2 repeat expansion in 463 Brazilian probands, of whom 404 had ALS/motor neuron disease and 67 FTD, and in 63 healthy controls in the southeastern region of Brazil. The highest frequencies of the C9orf72 mutation were in the ALS-FTD group (50% of familial and 17.6% of sporadic cases), although it was also present in 5% of pure ALS/motor neuron disease patients (11.8% of familial and 3.6% of sporadic cases) and in 7.1% of pure familial FTD. Among G4C2 repeat mutation carriers, 68.8% of the subjects who developed dementia symptoms were females. This frequency was significantly higher than the percentage reached by men with C9orf72 expansion who had this phenotype (p = 0.047). No abnormal repeat expansion was found in control groups. Inclusion of the C9orf72 genetic test in the molecular panels for Brazilian populations with these neurodegenerative diseases should be strongly considered.

AB - Horticulture was shown to represent a well-being source for older adults, encompassing the physical, mental and social domains. Aim of this pilot study was to contribute to extant literature through the investigation of the quality of experience associated with horticultural versus occupational activities. A group of 11 older residents of a nursing home were involved in a crossover study with a baseline measure. Participants attended weekly horticultural and occupational sessions for two six-week cycles. Experience Sampling Method was administered before the program and after each session, to assess participants' levels of happiness, concentration, sociability, involvement, challenges and stakes, and self-satisfaction. Altogether, 332 self-report questionnaires were collected. Findings showed that participants' levels of the cognitive and motivational variables increased during both activities, but horticulture was also perceived as providing higher challenges and stakes, and improving self-satisfaction. Results can have practical implications for well-being promotion among older adults through meaningful activity engagement. PMID- 29449035 TI - Usage of density analysis based on micro-CT for studying lung injury associated with burn-blast combined injury. AB - BACKGROUND: Burn-blast combined injury is a kind of injury caused by heat and blast at the same time. The lung injury after burn-blast combined injuries is of primary importance, and investigation of lung injury is needed in the clinical care of patients. Computed tomography (CT) is one of the standard tools used to observe the anatomical basis and pathophysiology of acute lung injury. METHODS: We applied a method of fast 3D (three-dimensional) reconstruction to calculate the density value of the lung injury by CT analysis. Blast-injury group (BL group), burn-injury group (B group), burn-blast combined injury group (BBL group), and sham control group (C group) were established. Each group had 16 rats. The three-dimensional images of the lung tissue were obtained at 6h, 24h, and 48h according to the CT value. The average density of the whole lung, left lung, and right lung were measured. The lung tissues were paraffin-embedded and HE stained. Smith scoring was performed according to the pathological findings. RESULTS: In the BBL group, the density of the lung tissue was higher than those of the BL group and B group (P<0.01). The lung tissue density values at 24h after injury were higher than those at 6h and 48h after injury (P<0.01). Pathological results confirmed the changes of density analysis of the lung tissue. CONCLUSION: The results have indicated that density analysis through a CT scan can be used as a way to evaluate lung injury in a burn-blast injury.

AB - Light irradiation has been demonstrated to exert positive effects on gametes, and particularly on sperm. In effect, a high number of studies conducted in several species, including humans, mice, pigs, cattle and sheep, and using different light sources (such as lasers and light-emitting diodes) have demonstrated that photo-stimulation increases sperm motility. In addition, other works have shown that sperm fertilizing ability both in vitro and in vivo can be increased following light irradiation; there are also some evidences pointing out to an extend of lifespan of preserved semen. Notwithstanding, no study has reported a detrimental effect of visible light on DNA integrity. The mechanisms through which light exerts its effects are not completely elucidated, but mounting evidence gives cell photosensitizers, especially those present in the mitochondria, a vital role. Stimulating these molecules turns into an increase in the production of ATP and Ca2+ influx, which contributes to explain the effects of light upon spermatozoa. Additionally, the presence of opsins in spermatozoa as well as the potential influence of light on the conformation of other proteins may also be involved in the sperm response to light. However, there are still a significant number of points that need to be addressed and their elucidation may contribute to increase the utilization of light irradiation for sperm preservation and ART. PMID- 29449038 TI - One year daily changes in fecal sexual steroids of two captive female cheetahs (Acinonyx jubatus) in Italy. AB - The present study evaluated changes of fecal sexual steroids in two female cheetahs (Geijsha and Duchessa) in Northern Italy throughout one year. Wet feces were collected daily from two sibling animals of the same age, housed with conspecific males and managed in the same conditions, and estrogens and progestogens concentrations were analyzed by radioimmunoassay (RIA). Evidence of ovarian activity based on regular fluctuation in estrogen excretion was demonstrated in both females. None of the animals was continuously cycling, as follicular activity was interrupted by anestrous periods, during the spring and early winter. No significant increases of progestogens were recorded after the estrogen peaks, indicating that induced or spontaneous ovulations did not occur during the observation period. The wavelet decomposition evidenced the temporal pattern of ovarian activity in the two females, underlying throughout the year a more pronounced rhythmical ovarian estrogenic activity in Geijsha than in Duchessa. However, this statistical approach had a smoothing effect in depicting the hormonal patterns and the number of follicular phases might be lower than that revealed by the iterative method. In this study, RIA on wet feces performed very well to determine sexual steroid concentrations, and an ovarian activity interrupted by anestrous periods along the year in captive cheetahs co-housed in a small group was demonstrated. More information on estrous behavior of captive cheetahs were obtained in this study, but the effects of husbandry and management conditions on natural reproductive physiology of this species remain to elucidate.

PMID- 29449040 TI - Xenon adsorption on geological media and implications for radionuclide signatures. AB - The detection of radioactive noble gases is a primary technology for verifying compliance with the pending Comprehensive Nuclear-Test-Ban Treaty. A fundamental challenge in applying this technology for detecting underground nuclear explosions is estimating the timing and magnitude of the radionuclide signatures. While the primary mechanism for transport is advective transport, either through barometric pumping or thermally driven advection, diffusive transport in the surrounding matrix also plays a secondary role. From the study of primordial noble gas signatures, it is known that xenon has a strong physical adsorption affinity in shale formations. Given the unselective nature of physical adsorption, isotherm measurements reported here show that non-trivial amounts of xenon adsorb on a variety of media, in addition to shale. A dual-porosity model is then discussed demonstrating that sorption amplifies the diffusive uptake of an adsorbing matrix from a fracture. This effect may reduce the radioxenon signature down to approximately one-tenth, similar to primordial xenon isotopic signatures.

PMID- 29449041 TI - Biomechanical simulation of traumatic brain injury in the rat. AB - BACKGROUND: Traumatic brain injury poses an enormous clinical challenge. Rats are the animals most widely used in pre-clinical experiments. Biomechanical simulations of these experiments predict the distribution of mechanical stress and strain across key tissues. It is in theory possible to dramatically increase our understanding of traumatic brain injury pathophysiology by correlating stress and strain with histological and functional injury outcomes. This review summarizes the state of the art in biomechanical simulation of traumatic brain injury in the rat. It also places this body of knowledge in the context of the wider effort to understand traumatic brain injury in rats and in humans. METHODS: Peer-reviewed research articles on biomechanical simulation of traumatic brain injury in the rat were reviewed and summarized. FINDINGS: When mathematical models of traumatic brain injury in the rat first emerged, they relied on scant data regarding biomechanical properties. The data on relevant biomechanical properties has increased recently. However, experimental models of traumatic brain injury in the rat have also become less homogeneous. New and modified models have emerged that are biomechanically distinct from traditional models. INTERPRETATION: Important progress in mathematical modeling and measurement of biomechanical properties has led to credible, predictive simulations of traditional, experimental models of traumatic brain injury in the rat, such as controlled cortical impact. However, recent trends such as the increasing popularity of closed head models and blast models create new biomechanical challenges. Investigators studying rat brain biomechanics must continue to innovate to keep pace with these developments.

PMID- 29449045 TI - How to measure glucocorticoid receptor's sensitivity in patients with stress related psychiatric disorders. AB - Stress is a state of derailed homeostasis and a main environmental risk factor for psychiatric diseases. Chronic or uncontrollable stress may lead to a dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis, which is a common feature of stress-related psychiatric disorders. One of the key mechanisms underlying a disturbed HPA axis is an impaired function of the glucocorticoid receptor (GR) with an enhanced or reduced feedback sensitivity for glucocorticoids and subsequently altered concentrations of peripheral cortisol. GR function is regulated by a multiprotein complex including the different expression of the hsp90 co-chaperone FK 506 binding protein 51 (FKBP5) that may be genetically determined or acquired in response to stressful stimuli. Specific patterns of a dysregulation of the HPA axis and GR function are found in different stress-related psychiatric entities e.g. major depression, job-related exhaustion or posttraumatic stress disorder. GR challenge tests like the dexamethasone-suppression test (DST), the dexamethasone-corticotropin-releasing hormone (dex-CRH) test or most recently the analysis of the dexamethasone-induced gene expression are employed to sensitively measure HPA axis activity in these disorders. They provide information for a stratification of phenotypic similar but neurobiological diverse psychiatric disorders. In this review we present a synopsis of GR challenge tests with a focus on the application of the DST, the CRH test and the dex-CRH test as well as the dexamethasone-induced gene expression in stress-related psychiatric entities.

PMID- 29449047 TI - Validation and update of a lymph node metastasis prediction model for breast cancer. AB - PURPOSE: This study aimed to validate and update a model for predicting the risk of axillary lymph node (ALN) metastasis for assisting clinical decision-making. METHODS: We included breast cancer patients diagnosed at six Dutch hospitals between 2011 and 2015 to validate the original model which includes six variables: clinical tumor size, tumor grade, estrogen receptor status, lymph node longest axis, cortical thickness and hilum status as detected by ultrasonography. Subsequently, we updated the original model using generalized linear model (GLM) tree analysis and by adjusting its intercept and slope. The area under the receiver operator characteristic curve (AUC) and calibration curve were used to assess the original and updated models. Clinical usefulness of the model was evaluated by false-negative rates (FNRs) at different cut-off points for the predictive probability. RESULTS: Data from 1416 patients were analyzed. The AUC for the original model was 0.774. Patients were classified into four risk groups by GLM analysis, for which four updated models were created. The AUC for the updated models was 0.812. The calibration curves showed that the updated model predictions were better in agreement with actual observations than the original model predictions. FNRs of the updated models were lower than the preset 10% at all cut-off points when the predictive probability was less than 12.0%. CONCLUSIONS: The original model showed good performance in the Dutch validation population. The updated models resulted in more accurate ALN metastasis prediction and could be useful preoperative tools in selecting low-risk patients for omission of axillary surgery. PMID- 29449049 TI - Extended-spectrum beta-lactamase-producing Enterobacteriaceae, national study of antimicrobial treatment for pediatric urinary tract infection. AB - OBJECTIVE: To evaluate clinical practices for ESBL-producing urinary tract infection (UTI) in France. METHODS: We performed an observational, retrospective, cross-sectional, hospital-based study in 22 pediatric departments of university or secondary care hospitals. We collected data of the last five patients presenting with ESBL-producing UTI in 2012 and the physicians' therapeutic approach to two case vignettes of acute non-septic ESBL-producing pyelonephritis (7-month-old girl) and cystitis (30-month-old girl). The adequacy of the therapeutic decision was analyzed by a panel of independent infectious disease experts. RESULTS: A total of 80 case patients of ESBL-producing UTI were collected: 54 with acute pyelonephritis (mean age: 28 months, female: 66%), of whom 98% received an intravenous ESBL-adapted antibiotic treatment and 55% a two drug antibiotic therapy. Carbapenems were used in 56% of cases and aminoglycosides in 36%. Of the 26 cystitis patients (mean age: 5 years, female: 73%), 85% were treated with antibiotics, including three intravenously (carbapenems=2). For the case vignettes, physicians (n=85) would have treated the pyelonephritis patient with carbapenems (76%) and/or aminoglycosides (68%); 71% would have used a two-drug antibiotic treatment. The cystitis patient would have been treated intravenously by 29% of physicians; 8% would have used a two-drug antibiotic treatment, 16% would have prescribed carbapenems, and 11% aminoglycosides. Antibiotic treatments were deemed appropriate in 37% of cases. CONCLUSIONS: Antimicrobial treatment for ESBL-producing UTI greatly varies, and carbapenems are excessively prescribed. Specific guidelines for ESBL infections are required. PMID- 29449050 TI - A novel truncating mutation in FLNA causes periventricular nodular heterotopia, Ehlers-Danlos-like collagenopathy and macrothrombocytopenia. AB - INTRODUCTION: Filamin A (FLNA) is located in Xq28, and encodes the actin binding protein, filamin A. A mutation in FLNA is the most common cause of periventricular nodular heterotopia (PVNH), but a clear phenotype-genotype correlation has not been established. Indeed, some patients with a FLNA mutation have recently been shown to additionally have Ehlers-Danlos-like collagenopathy or macrothrombocytopenia. In an attempt to establish a clearer correlation between clinical symptoms and genotype, we have investigated a phenotype that involves thrombocytopenia in a patient with a truncation of the FLNA gene. CASE REPORT: We present the case of a 4-year-old girl who, at birth, showed a ventral hernia. At 2 months of age, she was diagnosed with patent ductus arteriosus (PDA) and aortic valve regurgitation. At 11 months, she underwent ligation of the PDA. She was also diagnosed with diaphragmatic eventration by a preoperative test. At 19 months, motor developmental delay was noted, and brain MRI revealed bilateral PVNH with mega cisterna magna. Presently, there is no evidence of epilepsy, intellectual disability or motor developmental delay. She has chronic, mild thrombocytopenia, and a platelet count that transiently decreases after viral infection. Dilation of the ascending aorta is progressing gradually. Genetic testing revealed a de novo nonsense heterozygous mutation in FLNA (NM_001456.3: c.1621G > T; p.Glu541Ter). Immunofluorescence staining of a peripheral blood smear showed a lack of filamin A expression in 21.1% of her platelets. These filamin A-negative platelets were slightly larger than her normal platelets. CONCLUSION: Our data suggests immunofluorescence staining of peripheral blood smears is a convenient diagnostic approach to identify patients with a FLNA mutation, which will facilitate further investigation of the correlation between FLNA mutations and patient phenotype.

PMID- 29449051 TI - Differences in the validity of a visual estimation method for determining patients' meal intake between various meal types and supplied food items. AB - BACKGROUND & AIMS: The aim of this study was to examine differences in the validity of a visual estimation method for determining patients' meal intake between various meal types and supplied food items in hospitals and to find factors influencing the validity of a visual estimation method. METHODS: There are two procedures by which we obtained the information on dietary intake of the patients in these hospitals. These are both by visual assessment from the meal trays at the time of their clearing, by the attending nursing staff and by weighing conducted by researchers. The following criteria are set for the target trays: A) standard or therapeutic meals, which are monitored by a doctor, for energy and/or protein and/or sodium; B) regular, bite-sized, minced and pureed meal texture, and C) half-portion meals. Visual assessment results were tested for their validity by comparing with the corresponding results of weighing. Differences between these two methods indicated the estimated and absolute values of nutrient intake. RESULTS: A total of 255 (76.1%) trays were included in the analysis out of the 335 possible trays and the results indicated that the energy consumption estimates by visual or weighing procedures are not significantly different (412 +/- 173 kcal, p = 0.15). However, the mean protein consumption was significantly different (16.3 +/- 6.7 g/tray, p < 0.01) between the two procedures. Compared with standard meals (38 +/- 45 kcal, 1.9 +/- 2.5 g/tray), raters significantly misestimated the energy and protein intake of half-portion meals (78 +/- 65 kcal, 2.8 +/- 2.2 g/tray, p = 0.01) but accurately estimated the protein intake of protein controlled meals (0.5 +/- 0.6 g/tray, p = 0.03). Trays adding supplied food items were significantly misestimated for energy intake (66 +/- 58 kcal/tray) compared to trays with no additions (32 +/- 39 kcal/tray, p < 0.01). Moreover, the results of multivariable analysis demonstrated that supplied food items were significantly associated with increased odds of a difference between the two methods (OR: 3.84; 95% confidence interval [CI]: 1.07-13.85). CONCLUSIONS: There were high correlations between the visual estimation method and the weighing method measuring patients' dietary intake for various meal types and textures, except for meals with added supplied food items. Nursing staff need to be attentive to supplied food items. PMID- 29449053 TI - Genetic and epigenetic alterations in the tumour, tumour margins, and normal buccal mucosa of patients with oral cancer. AB - Despite adequate surgical resection, oral squamous cell carcinoma (OSCC) shows a high rate of recurrence and metastasis, which could be explained by the presence of molecular alterations in seemingly normal tumour margins and the entire oral mucosa. The aims of this study were (1) to assess the presence of gene amplification (c-Myc and HER2) and promoter methylation (p14 and p16) in the tumours, tumour margins, and unaffected oral mucosa of 40 OSCC patients, and (2) to evaluate the possibility of using these alterations as prognostic markers. c Myc and HER2 genes were quantified by means of real-time PCR (qPCR), and p14 and p16 methylation status was determined by methylation-specific PCR (MSP PCR). All tissues examined exhibited molecular alterations in various proportions. Tumour tissues, as expected, showed the highest prevalence of alterations, while oral mucosa showed the lowest. Multiple alterations (co-alterations) in tumours and tumour margins were significantly more frequent than in unaffected oral mucosa (P<0.001 and P=0.027, respectively). HER2 amplification in margin tissue (P<0.001) and swabs (P=0.013), as well as the existence of three co-alterations in margins (P=0.001) and macroscopically unaffected oral mucosa (P<0.001) were correlated with shorter disease-specific survival. PMID- 29449054 TI - Second generation antipsychotic-induced mitochondrial alterations: Implications for increased risk of metabolic syndrome in patients with schizophrenia. AB - Metabolic syndrome (MetS) is seen more frequently in persons with schizophrenia than in the general population, and these metabolic abnormalities are further aggravated by second generation antipsychotic (SGA) drugs. Although the underlying mechanisms responsible for the increased prevalence of MetS among patients under SGA treatment are not well understood, alterations in mitochondria function have been implicated. We performed a comprehensive evaluation of the role of mitochondrial dysfunction in the pathophysiology of drug-induced MetS in schizophrenia. We found a downregulation in genes encoding subunits of the electron transport chain complexes (ETC), enzyme activity, and mitochondrial dynamics in peripheral blood cells from patients at high-risk for MetS. Additionally, we evaluated several markers of energy metabolism in lymphoblastoid cell lines from patients with schizophrenia and controls following exposure to antipsychotics. We found that the high-risk drugs clozapine and olanzapine induced a general down-regulation of genes involved in the ETC, as well as decreased activities of the corresponding enzymes, ATP levels and a significant decrease in all the functional parameters of mitochondrial oxygen consumption in cells from patients and controls. We also observed that the medium-risk SGA quetiapine decreased oxygen consumption and respiratory control ratio in controls and patients. Additionally, clozapine and olanzapine induced a downregulation of Drp1 and Mfn2 both in terms of mRNA and protein levels. Together, these data suggest that an intrinsic defect in multiple components of oxidative metabolism may contribute to the increased prevalence of MetS in patients under treatment with SGAs known to cause risk for MetS. PMID- 29449055 TI - Adjunctive antidepressants in bipolar depression: A cohort study of six- and twelve-months rehospitalization rates. AB - Although antidepressants (ADs) are widely used in bipolar depression, there is weak evidence for their effectiveness and safety in this condition. Furthermore, there is a paucity of studies on the risk-benefit ratio of AD maintenance treatment in bipolar disorder (BD). We compared rehospitalization rates of patients with BD-I depressive episode who were discharged with mood stabilizers (MSs) and/or atypical antipsychotics (AAPs) with or without adjunctive AD. Ninety eight patients with BD-I who were hospitalized with a depressive episode between 2005 and 2013 were retrospectively followed for 6-months and 1-year rehospitalization rates, as well as time to rehospitalization, according to treatment at discharge: MSs and/or AAPs with or without AD. Multivariable survival models adjusted for covariates known to influence rehospitalization were conducted. Six-months and 1-year rehospitalization rates were significantly lower in the adjunctive-AD treatment group compared to the no-AD group (9.2% vs. 36.4%, P = .001, power = 0.87 and 12.3% vs. 42.4%, P = .001, power = 0.89, respectively). Time to rehospitalization within 6-months and 1-year was significantly longer in the adjunctive-AD treatment group (169.9 vs 141 days, P = .001 and 335.6 vs 252.3 days, P = .001, respectively). Adjunctive-AD treatment at discharge reduced significantly the adjusted risk of rehospitalization within 6 months (HR = 0.081, 95% CI: 0.016-0.412, P = 0.002) and 1-year (HR = 0.149, 95% CI: 0.041-0.536, P = 0.004). Moreover, adjunctive-AD treatment did not increase rehospitalization rates of manic episode. In conclusion, adjunctive-AD therapy to MS/AAP at discharge from BD-I depressive episode hospitalization is associated with a lower rate of and a longer time to rehospitalization during a 1-year follow up period.

PMID- 29449057 TI - Prognostic Significance of Human Papilloma Virus and p16 Expression in Patients with Vulvar Squamous Cell Carcinoma who Received Radiotherapy. AB - AIMS: Human papilloma virus (HPV) has been identified as an aetiological agent in a subset of patients with vulvar squamous cell carcinoma (VSCC). The prognostic role of HPV status in VSCC patients treated with radiotherapy has not yet been determined. We investigated the associations between HPV, p16 and clinical outcome in these women. MATERIALS AND METHODS: Patients undergoing potentially curative radiation treatment for VSCC at a single institution from 2000 to 2009 were retrospectively identified. Those who received definitive or peri-operative radiotherapy as part of treatment, and who had available pathological specimens, were included for analysis. HPV infection was detected using Roche Linear array hybridisation and p16 by immunohistochemistry. The locoregional relapse (LRR) rate was estimated using a cumulative incidence function to account for competing risks. Disease-free survival (DFS) and overall survival were analysed using the Kaplan-Meier method. The median follow-up was 4.9 years. RESULTS: Forty patients were suitable for analysis, with a median age of 69.5 years. HPV was detected in 14/40 (35%) patients, HPV16 being the most common serotype (79%). Patients with HPV-positive tumours had lower 5 year LRR compared with those with HPV-negative tumours (14.3% versus 79.3%, Gray test P = 0.003). Tumour p16 positivity was also associated with lower 5 year LRR (15.4% versus 81.2%, Gray test P = 0.002). Patients with p16-positive tumours had higher 5 year DFS compared with those with p16-negative tumours (62% versus 7%, Log-rank test P = 0.02). CONCLUSIONS: We have identified a favourable prognostic group in VSCC, with p16-positive patients showing improved outcomes. p16 has the potential to be a predictive marker allowing the identification of women more likely to have a favourable response to radiotherapy. PMID- 29449058 TI - [Epidemiology of lower extremity artery disease]. AB - It is estimated that more than 200 million individuals are affected by lower extremity artery disease (LEAD) worldwide. This prevalence has increased between 2000 and 2010 by 25%, especially in low/middle income countries. In France, about one million people are affected by this condition. Almost two-thirds of patients with LEAD are asymptomatic. This explains the interest of the measurement of the ankle-brachial index (ABI), an objective and harmless diagnostic tool. An ABI<=0.90 is considered as diagnostic for LEAD. The detection of symptomatic LEAD requires standardized questionnaires identifying intermittent claudication. Epidemiological studies on chronic limb-threatening ischemia (CLTI) - the most severe presentation of the disease - are scarce: the prevalence is estimated around 0.5-2.0% after the age of 40, mostly affecting elderly people. Similar to other atherosclerotic diseases, the risk factors are multiple (genetic factors, traditional risk factors, metabolic and inflammatory factors, socioeconomic factors), with different weighs of association as compared to coronary artery diseases. Due to their high prevalence and strength of association, cigarette smoking and hypertension are the most frequent purveyors of this disease in population. Diabetes mellitus is a strong risk factor, and its increasing prevalence contributes to the global epidemics of LEAD. In claudicants, the 5 year amputation risk is estimated at 5%, increasing to 25% at one year in case of CLTI. However, the main risk is related to general cardiovascular events. It is estimated that patients with LEAD present concomitantly coronary and cerebrovascular disease in respectively 50% and 20% of cases. The non cardiovascular mortality, especially related to cancer, is also higher than in general population. Overall, the control of traditional risk factors has a beneficial effect both for the limb and general prognosis.

PMID- 29449060 TI - The aprosody of schizophrenia: Computationally derived acoustic phonetic underpinnings of monotone speech. AB - OBJECTIVE: Acoustic phonetic methods are useful in examining some symptoms of schizophrenia; we used such methods to understand the underpinnings of aprosody. We hypothesized that, compared to controls and patients without clinically rated aprosody, patients with aprosody would exhibit reduced variability in: pitch (F0), jaw/mouth opening and tongue height (formant F1), tongue front/back position and/or lip rounding (formant F2), and intensity/loudness. METHODS: Audiorecorded speech was obtained from 98 patients (including 25 with clinically rated aprosody and 29 without) and 102 unaffected controls using five tasks: one describing a drawing, two based on spontaneous speech elicited through a question (Tasks 2 and 3), and two based on reading prose excerpts (Tasks 4 and 5). We compared groups on variation in pitch (F0), formant F1 and F2, and intensity/loudness. RESULTS: Regarding pitch variation, patients with aprosody differed significantly from controls in Task 5 in both unadjusted tests and those adjusted for sociodemographics. For the standard deviation (SD) of F1, no significant differences were found in adjusted tests. Regarding SD of F2, patients with aprosody had lower values than controls in Task 3, 4, and 5. For variation in intensity/loudness, patients with aprosody had lower values than patients without aprosody and controls across the five tasks. CONCLUSIONS: Findings could represent a step toward developing new methods for measuring and tracking the severity of this specific negative symptom using acoustic phonetic parameters; such work is relevant to other psychiatric and neurological disorders. PMID- 29449061 TI - C4A mRNA expression in PBMCs predicts the presence and severity of delusions in schizophrenia and bipolar disorder with psychosis. AB - Altered immune function is an established finding in psychotic disorders such as schizophrenia and bipolar disorder with psychosis, though its role in their development and progression remains to be understood. Evidence suggests altered JAK-STAT1 pathway activity in peripheral blood cells from participants with schizophrenia compared to controls. Activation of this pathway leads to increased expression of complement component 4A (C4A), which has recently been implicated in schizophrenia. Here, we examine mRNA expression of C4A in peripheral blood cells from participants with schizophrenia, bipolar disorder and controls. STAT1 and IRF-1 mRNA expression are included as measures of JAK-STAT1 pathway activation in the same participants. Further, we examine the association of each genes mRNA expression with clinical symptom measures using the Positive and Negative Syndrome Scale (PANSS) and the Psychotic Symptom Rating Scale (PSYRATS). We demonstrate that C4A, STAT1 and IRF-1 mRNA expression levels are correlated across the entire sample, indicating shared transcriptional regulatory mechanisms. Further, we show that C4A mRNA expression alone is positively associated with psychotic symptomatology, specifically the presence and severity of delusions. These findings are noteworthy given recent findings that demonstrate a critical role for complement proteins in synaptic pruning, alterations of which are proposed to contribute to psychopathology in psychosis.

AB - OBJECTIVE: The objective of this study was to examine the perceptual structure and acoustic characteristics of speech of patients with adductor spasmodic dysphonia (ADSD) in Mandarin. STUDY DESIGN: Case-Control Study MATERIALS AND METHODS: For the estimation of dysphonia level, perceptual and acoustic analysis were used for patients with ADSD (N = 20) and the control group (N = 20) that are Mandarin-Chinese speakers. For both subgroups, a sustained vowel and connected speech samples were obtained. The difference of perceptual and acoustic parameters between the two subgroups was assessed and analyzed. RESULTS: For acoustic assessment, the percentage of phonatory breaks (PBs) of connected reading and the percentage of aperiodic segments and frequency shifts (FS) of vowel and reading in patients with ADSD were significantly worse than controls, the mean harmonics-to-noise ratio and the fundamental frequency standard deviation of vowel as well. For perceptual evaluation, the rating of speech and vowel in patients with ADSD are significantly higher than controls. The percentage of aberrant acoustic events (PB, frequency shift, and aperiodic segment) and the fundamental frequency standard deviation and mean harmonics-to noise ratio were significantly correlated with the perceptual rating in the vowel and reading productions. CONCLUSIONS: The perceptual and acoustic parameters of connected vowel and reading in patients with ADSD are worse than those in normal controls, and could validly and reliably estimate dysphonia of ADSD in Mandarin speaking Chinese. PMID- 29449063 TI - Comparison of Post-therapy Dysphonic Voices and Normal Voices. AB - PURPOSE: The purpose of the present investigation was to compare the voices of post-therapy dysphonic participants with participants who have normal voices to determine how close the corrected voices approached normal vocal levels. The present investigation is a follow-up to the authors' previous research in which dysphonic participants, with voices ranging from moderate-to-severe dysphonia, were evaluated pre- and post therapy using the Dysphonic Severity Percentage scale and the interval scale. METHODS: In the present study, five raters, three speech-language pathologists experienced in assessing dysphonia, and two trained speech-language pathology college students evaluated 20 participants with normal voices under the same two conditions as those of the corrected participants-when reading a paragraph aloud and during spontaneous speech. While listening to the recordings of the normal voices, the raters tallied any dysphonic syllables produced by the participants to obtain a Dysphonic Severity Percentage for both paragraph reading and spontaneous speech. The raters also evaluated the normal voices on the interval scale. These data were compared with those of the post therapy participants, who were evaluated under the same conditions and methods pre- and post therapy. RESULTS AND CONCLUSION: The dysphonic participants' voices improved significantly post therapy in comparison with their pretherapy result; their improvement, however, was not commensurate with the voices of the normal participants, and the data showed a significant difference between the two groups. Both evaluation scales reflected a high agreement among raters. PMID- 29449064 TI - Pain-related psychological issues in hand therapy. AB - STUDY DESIGN: Literature review. INTRODUCTION: Pain is a subjective experience that results from the modulation of nociception conveyed to the brain via the nervous system. Perception of pain takes place when potential or actual noxious stimuli are appraised as threats of injury. This appraisal is influenced by one's cognitions and emotions based on her/his pain-related experiences, which are processed in the forebrain and limbic areas of the brain. Unarguably, patients' psychological factors such as cognitions (eg, pain catastrophizing), emotions (eg, depression), and pain-related behaviors (eg, avoidance) can influence perceived pain intensity, disability, and treatment outcomes. Therefore, hand therapists should address the patient pain experience using a biopsychosocial approach. However, in hand therapy, a biomedical perspective predominates in pain management by focusing solely on tissue healing. PURPOSE OF THE STUDY: This review aims to raise awareness among hand therapists of the impact of pain related psychological factors. METHODS AND RESULTS: This literature review allowed to describe (1) how the neurophysiological mechanisms of pain can be influenced by various psychological factors, (2) several evidence-based interventions that can be integrated into hand therapy to address these psychological issues, and (3) some approaches of psychotherapy for patients with maladaptive pain experiences. DISCUSSION AND CONCLUSION: Restoration of sensory and motor functions as well as alleviating pain is at the core of hand therapy. Numerous psychological factors including patients' beliefs, cognitions, and emotions alter their pain experience and may impact on their outcomes. Decoding the biopsychosocial components of the patients' pain is thus essential for hand therapists. PMID- 29449065 TI - Effects of fluoride and epigallocatechin gallate on soft-drink-induced dental erosion of enamel and root dentin. AB - BACKGROUND/PURPOSE: Fluoride and epigallocatechin gallate (EGCG) have been proven to prevent dental caries. The purpose of this study was to evaluate the effects of fluoride and EGCG on soft-drink-induced dental erosion in vitro. METHODS: Forty enamel and dentin specimens were prepared from extracted human teeth. The specimens were divided into 4 groups and treated separately with distilled water (as control), 0.5 M sodium fluoride (NF), 400 MUM EGCG (EG), and a solution containing 0.5 M NaF and 400 MUM EGCG (FG). Cyclic erosive treatment was performed according to the experimental procedures. The specimens were analyzed using laser scanning confocal microscopy, scanning electron microscopy, and a microhardness tester. The data were analyzed using ANOVA and Bonferroni's post hoc test. The significance level was set at 5%. RESULTS: The amount of substance loss was lower in the NF and EG groups than in the control group (p < 0.05). The erosion-caused substance loss was more pronounced in the dentin than in the enamel specimens. Surface microhardness loss was lower in the NF and EG groups than in the control group (p < 0.05). The diameter of the dentinal tubule was wider in the control group than in the NF and EG groups (p < 0.05). No combined effects were observed in the FG group. CONCLUSION: Both fluoride and EGCG are effective in preventing soft-drink-induced erosion compared with the control group. Fluoride and EGCG may interfere with each other. The mechanisms of the anti-erosive effect need to be explored in the future. PMID- 29449066 TI - Characteristics of headache in relation to the manifestation of Susac syndrome. AB - Susac syndrome is characterized by a clinical triad of encephalopathy, branch retinal artery occlusion, and hearing loss. Due to the absence of the whole complex of the triad in the majority of cases at disease presentation, the syndrome often remains underdiagnosed and untreated. Headache is estimated to affect up to 80% of Susac syndrome patients, but the relevance of headache characteristics and profile is not yet clear. The proposed diagnostic criteria of the European Susac Consortium acknowledge headache as a possible brain manifestation if it is new, described as migrainous or oppressive, and precedes the other symptoms by not more than 6 months. Herein, a case series of different migraine-like headache associations attributed to Susac syndrome is presented and discussed in relevance with previously published literature. Our patients experienced different presentations of migraine-like headache related with Susac syndrome: exacerbation and chronification of headache just before the manifestation of the first symptoms of Susac syndrome, the manifestation of headache during the first episode of the syndrome, and an increasing frequency of headache during the course of the disease. The diagnosis of Susac syndrome in all three cases was confirmed by typical clinical symptoms and findings in retinal fluorescein angiography, audiometry, and brain magnetic resonance imaging, based on the diagnostic criteria of the European Susac Consortium. Based on the analysis of our presented cases, we conclude that headache attributed to Susac's syndrome is of migraine-like type but could be of different presentations in relation to the onset of the syndrome. PMID- 29449068 TI - Chemokines beyond chemo-attraction: CXCL10 and its significant role in cancer and autoimmunity. AB - Chemokines are mostly known for their chemotactic properties, and less for their ability to direct the biological function of target cells, including T cells. The current review focuses on a key chemokine named CXCL10 and its role in directing the migratory propertied and biological function of CD4+ and CD8+ T cells in the context of cancer and inflammatory autoimmunity. CXCR3 is a chemokine receptor that is abundant on CD4+ T cells, CD8+ T cells and NK cells. It has three known ligands: CXCL9, CXCL10 and CXCL11. Different studies, including those coming form our laboratory, indicated that aside of attracting CD8+ and CD4+ effector T cells to tumor sites and sites of inflammation CXCL10 directs the polarization and potentiates the biological function of these cells. This makes CXCL10 a "key driver chemokine" and a valid target for therapy of autoimmune diseases such as Inflammatory Bowl's Disease, Multiple Sclerosis, Rheumatoid arthritis and others. As for cancer this motivated different groups, including our group to develop CXCL10 based therapies for cancer due to its ability to enhance T-dependent anti cancer immunity. The current review summarizes these findings and their potential translational implication. PMID- 29449067 TI - The journey of radiofrequency-assisted liver resection.

AB - Shellfish aquaculture in Ofunato Bay, Northeast Japan, was seriously damaged by a tsunami generated by the Great East Japan Earthquake, March 11th, 2011, accompanied by paralytic shellfish poisoning (PSP) outbreaks caused by Alexandrium tamarense (Dinophyceae). To understand longer future trends of PSP, an investigation was made of the historical occurrence and causes of Alexandrium outbreaks after the tsunami. Vertical distributions of Alexandrium cysts in two sediment-cores from Ofunato Bay revealed that the sediments above ca. 25 cm were eroded, re-suspended and re-deposited, and they included unusually abundant Alexandrium cysts. This abundance of cysts was due to re-deposition of older sediments by the tsunami. The first Ofunato Bay PSP incident was in 1961 after the Chilean Earthquake tsunami and was probably caused by similar unusual blooms of Alexandrium germinated from older sediments as the Great East Japan tsunami, together with nutrient enrichment because of population increase at the start of shellfish aquaculture. PMID- 29449070 TI - Physiological effects of marine natural organic matter and metals in early life stages of the North Pacific native marine mussel Mytilus trossulus; a comparison with the invasive Mytilus galloprovincialis. AB - The role of seawater NOM in reducing metal toxicity for marine organisms is not well understood. We investigated the effects of five different marine NOMs (two autochthonous, one allochthonous, two of mixed origin, at 8 mg C/L), three metals (6 MUg Cu/L; 20 MUg Pb/L; 25 MUg Zn/L), and combinations between them, to early life stages of Mytilus trossulus (a North Pacific native) in 48-h tests. Endpoints were whole body Ca2++Mg2+-ATPase activity, carbonic anhydrase (CA) activity and lipid peroxidation. Comparisons were made with previously reported tests (identical conditions) on the invasive M. galloprovincialis. Unexposed M. trossulus had lower Ca2++Mg2+-ATPase but similar baseline CA activity and lipid peroxidation to unexposed M. galloprovincialis. NOMs alone induced increased enzyme activities, and increased lipid peroxidation, but the latter did not occur with NOMs of mixed origin in M. trossulus. There was no clear difference in the sensitivity to various NOMs between species. In M. trossulus, all three metals by themselves caused increases in lipid peroxidation, as did many metal-NOM combinations. The origin of the NOMs influenced the nature of the responses to NOM-metal combinations in both species, but no clear relationship to NOM chemistry was apparent. Overall, M. trossulus was more sensitive to metals and NOM-metal combinations, with a greater number of significant responses (27 versus 22 treatment endpoints, out of a total of 72) and a greater proportion of negative effects (81% versus 50%) than in M. galloprovincialis. Therefore, marine NOMs by themselves, as well as metals by themselves and NOM-metal combinations, can induce both positive and negative physiological responses. Lipid peroxidation appears to be a particularly common negative response. In future studies, NOM quality and mussel species should be considered since native M. trossulus and invasive M. galloprovincialis exhibited markedly different responses after exposure to the same environmental conditions. PMID- 29449071 TI - Do the morphological and functional traits of free-living marine nematodes mirror taxonomical diversity? AB - The taxonomical structure and diversity of nematode assemblages are the main attributes analyzed in ecology, but nematode adaptations to their habitats are still understudied. Accordingly, a survey on some known and other newly proposed morpho-functional traits was carried out in order to: determine if the morpho functional diversity of nematodes mirrors their taxonomical diversity; and assess potential nematode adaptations to sediment type and hydrodynamic stress. Morpho functional traits were investigated both singularly and together and showed significant differences related to these environmental factors. The greatest taxonomical and morpho-functional diversity was found in medium-coarse sand (M CS) and at an intermedium energy level (IEL). The M-CS and IEL were probably richer in micro-habitats and subject to a low selective pressure, hosting nematodes with a wide range of adaptations. The mirroring of morpho-functional diversity with taxonomical diversity is crucial for the future growth of the use of nematodes in biomonitoring. This is because the study of their morpho functional traits could reduce the level of work involved and the costs of any analyses. PMID- 29449072 TI - MERRF Classification: Implications for Diagnosis and Clinical Trials. AB - BACKGROUND: Given the etiologic heterogeneity of disease classification using clinical phenomenology, we employed contemporary criteria to classify variants associated with myoclonic epilepsy with ragged-red fibers (MERRF) syndrome and to assess the strength of evidence of gene-disease associations. Standardized approaches are used to clarify the definition of MERRF, which is essential for patient diagnosis, patient classification, and clinical trial design. METHODS: Systematic literature and database search with application of standardized assessment of gene-disease relationships using modified Smith criteria and of variants reported to be associated with MERRF using modified Yarham criteria. RESULTS: Review of available evidence supports a gene-disease association for two MT-tRNAs and for POLG. Using modified Smith criteria, definitive evidence of a MERRF gene-disease association is identified for MT-TK. Strong gene-disease evidence is present for MT-TL1 and POLG. Functional assays that directly associate variants with oxidative phosphorylation impairment were critical to mtDNA variant classification. In silico analysis was of limited utility to the assessment of individual MT-tRNA variants. With the use of contemporary classification criteria, several mtDNA variants previously reported as pathogenic or possibly pathogenic are reclassified as neutral variants. CONCLUSIONS: MERRF is primarily an MT-TK disease, with pathogenic variants in this gene accounting for ~90% of MERRF patients. Although MERRF is phenotypically and genotypically heterogeneous, myoclonic epilepsy is the clinical feature that distinguishes MERRF from other categories of mitochondrial disorders. Given its low frequency in mitochondrial disorders, myoclonic epilepsy is not explained simply by an impairment of cellular energetics. Although MERRF phenocopies can occur in other genes, additional data are needed to establish a MERRF disease-gene association. This approach to MERRF emphasizes standardized classification rather than clinical phenomenology, thus improving patient diagnosis and clinical trial design. PMID- 29449073 TI - Healthy minds 0-100 years: Optimising the use of European brain imaging cohorts ("Lifebrain"). AB - The main objective of "Lifebrain" is to identify the determinants of brain, cognitive and mental (BCM) health at different stages of life. By integrating, harmonising and enriching major European neuroimaging studies across the life span, we will merge fine-grained BCM health measures of more than 5000 individuals. Longitudinal brain imaging, genetic and health data are available for a major part, as well as cognitive and mental health measures for the broader cohorts, exceeding 27,000 examinations in total. By linking these data to other databases and biobanks, including birth registries, national and regional archives, and by enriching them with a new online data collection and novel measures, we will address the risk factors and protective factors of BCM health. We will identify pathways through which risk and protective factors work and their moderators. Exploiting existing European infrastructures and initiatives, we hope to make major conceptual, methodological and analytical contributions towards large integrative cohorts and their efficient exploitation. We will thus provide novel information on BCM health maintenance, as well as the onset and course of BCM disorders. This will lay a foundation for earlier diagnosis of brain disorders, aberrant development and decline of BCM health, and translate into future preventive and therapeutic strategies. Aiming to improve clinical practice and public health we will work with stakeholders and health authorities, and thus provide the evidence base for prevention and intervention. PMID- 29449074 TI - Onychomycosis due to dermatophytes species in Iran: Prevalence rates, causative agents, predisposing factors and diagnosis based on microscopic morphometric findings. AB - OBJECTIVE: Onychomycosis (OM) or fungal nail infection is one of the most common fungal infections, which is increasingly prevalent. OM is caused by dermatophytes spp, yeasts and non-dermatophyte moulds (NDMs). The purpose of this study was to identify and determine the prevalence rates, predisposing factors and causative agents of OM using clinical symptoms and microscopic morphometric findings. MATERIALS AND METHODS: In the present study, 180 patients suspected of OM were evaluated by direct microscopy using KOH 20%, culturing in Mycosel and Sabouraud dextrose agar media and Olysia software for identifying the causative fungi of OM. RESULTS: From 180 referred patients, 118 (65.56%) had OM, of whom 79 (66.94%) were positive for infection with dermatophytes spp. Of the 79 cases, the commonest age group was 61-70 years (21%) with males being 46 (58.23%) and females being 33 (41.77%). Both the fingernail and toenail infections were most prevalent in male patients. Sex, diabetes and age above 60 years were significant predisposing factors for OM development. DLSO was observed as the only clinical pattern of OM and T. rubrum was the commonest dermatophyte isolate (49.34%). CONCLUSION: This study showed that T. rubrum was the most common dermatophyte agent of OM in Iran. PMID- 29449076 TI - Editorial Overview: Growth and development. PMID- 29449075 TI - Cardiac transplantation in children with Down syndrome, Turner syndrome, and other chromosomal anomalies: A multi-institutional outcomes analysis. AB - BACKGROUND: The purpose of this study was to describe the prevalence, characteristics, and outcomes in pediatric patients with chromosomal anomalies (CA) undergoing orthotopic heart transplantation (OHT). METHODS: A query of the database of the Pediatric Health Information System, a large administrative and billing database of 43 tertiary children's hospitals, was performed for the Years 2004 to 2016. Pediatric patients who received OHT were analyzed based on presence and type of CA. CA analyzed included: Down syndrome (DS); Turner syndrome (TS)/gonadal dysgenesis; conditions due to anomaly of unspecified chromosome; autosomal deletion; microdeletion; and autosomal anomaly. Healthcare-associated charge analysis during hospitalization for OHT and survival after OHT were assessed. RESULTS: A total of 3,080 hospitalizations were identified in which OHTs were performed. Of these OHTs, 64 (2.1%) were performed in patients with a concomitant diagnosis of CA. The presence of CA did not confer a higher risk of in-hospital mortality after OHT (odds ratio 1.2 [0.5 to 3.2], p = 0.651). Differences in in-hospital mortality between different types of CA, including DS and TS, did not reach statistical significance. Survival at 1-year post-OHT was similar in patients with CA compared to those without CA (p = 0.248). Length of stay after OHT was longer in patients with CA: 76 (interquartile range [IQR] 76 to 142 days vs 49 [IQR 21 to 98] days) (p < 0.001), respectively. Overall adjusted hospital charges were significantly higher in the CA group: $1.2 million (IQR $740,000 to $2.2 million) vs $792,000 (IQR $425,000 to $1.5 million] (p < 0.001), respectively. CONCLUSIONS: CA is present in ~2% of pediatric patients undergoing OHT. The presence of CA was not associated with increased mortality in pediatric patients undergoing OHT. Limitations of this study include the small number of patients available for analysis and a likely highly selective cohort of patients with CA.

PMID- 29449079 TI - Cost-Effectiveness of Ivabradine in the Treatment of Chronic Heart Failure. AB - BACKGROUND: In the Systolic Heart failure treatment with the If inhibitor Trial (SHIFT) randomised placebo-controlled trial, ivabradine was shown to reduce hospital admissions for worsening heart failure (HF) and deaths due to HF in patients with symptomatic systolic HF and an elevated resting heart rate (HR). This analysis evaluates the cost effectiveness of adding ivabradine to optimal standard HF treatment in patients with a HR>=77 bpm. METHODS: A Markov model was developed to assess the impact of ivabradine on mean survival and quality of life over a patient's lifetime (10 years). The hospitalisation and death rates were calculated using patient-level data from SHIFT. The reduction in quality of life due to HF hospitalisations was estimated directly from EQ-5D data collected in SHIFT. Australian costs were applied to the resource use from SHIFT. RESULTS: The modelled mean increase in survival with ivabradine was 0.115 years. The mean increase in quality-adjusted survival was 0.108 years. The average cost of ivabradine was A$2957 and the cost savings associated with a reduction in HF hospitalisations was A$1344. The cost per quality adjusted life year gained (QALYG) was A$14,905. The conservative approach to the modelled evaluation, as well as results of the sensitivity analysis, demonstrates that ivabradine is likely to be cost-effective in this indication. CONCLUSIONS: The conservative approach to the modelled evaluation, as well as results of the sensitivity analysis, demonstrates that ivabradine is a cost-effective treatment in the Australian setting for HF patients with a HR>=77 bpm on optimal standard therapy with a cost per QALYG similar or lower than that for other publicly funded treatments. PMID- 29449080 TI - Influence of exercise modality on cardiac parasympathetic and sympathetic indices during post-exercise recovery. AB - OBJECTIVES: This study investigated indirect measures of post-exercise parasympathetic reactivation (using heart-rate-variability, HRV) and sympathetic withdrawal (using systolic-time-intervals, STI) following upper- and lower-body exercise. DESIGN: Randomized, counter-balanced, crossover. METHODS: 13 males (age 26.4+/-4.7years) performed maximal arm-cranking (MAX-ARM) and leg-cycling (MAX LEG). Subsequently, participants undertook separate 8-min bouts of submaximal HR matched exercise of each mode (ARM and LEG). HRV (including natural-logarithm of root-mean-square-of-successive-differences, Ln-RMSSD) and STI (including pre ejection-period, PEP) were assessed throughout 10-min seated recovery. RESULTS: Peak-HR was higher (p=0.001) during MAX-LEG (182+/-7beatsmin-1) compared with MAX ARM (171+/-12beatsmin-1), while HR (p<0.001) and Ln-RMSSD (p=0.010) recovered more rapidly following MAX-ARM. PEP recovery was similar between maximal bouts (p=0.106). HR during submaximal exercise was 146+/-7 (LEG) and 144+/-8beatsmin-1 (LEG) (p=0.139). Recovery of HR and Ln-RMSSD was also similar between submaximal modalities, remaining below baseline throughout recovery (p<0.001). PEP was similar during submaximal exercise (LEG 70+/-6ms; ARM 72+/-9ms; p=0.471) although recovery was slower following ARM (p=0.021), with differences apparent from 1- to 10-min recovery (p<=0.036). By 10-min post-exercise, PEP recovered to baseline (132+/-21ms) following LEG (130+/-21ms; p=0.143), but not ARM (121+/-17ms; p=0.001). CONCLUSIONS: Compared with submaximal lower-body exercise, HR-matched upper-body exercise elicited a similar recovery of HR and HRV indices of parasympathetic reactivation, but delayed recovery of PEP (reflecting sympathetic withdrawal). Exercise modality appears to influence post-exercise parasympathetic reactivation and sympathetic withdrawal in an intensity-dependent manner. These results highlight the need for test standardization and may be relevant to multi discipline athletes and in clinical applications with varying modes of exercise testing. PMID- 29449081 TI - Urinary concentrations of benzophenone-type ultra violet light filters and reproductive parameters in young men. AB - BACKGROUND: Benzophenone (BP)-type ultraviolet (UV) light filters are chemicals frequently added to personal care products, insect repellents, sunscreens, and beverage and food packaging to diminish the harmful effects of UV sunlight on human skin or foodstuffs. BP-type UV filters have shown negative effects on male reproduction function in in vitro and animal models, but human epidemiologic studies are limited. The goal of this study was to examine associations between urinary concentrations of BP-type UV filters and semen quality and reproductive hormone levels. METHODS: This is a cross-sectional study with 215 young university students (18-23 years old) recruited between 2010 and 2011 in Southern Spain (Murcia Region). All men provided a urine, blood and semen sample on a single day. Urinary concentrations of 2,4-dihydroxybenzophenone (BP-1); 2,2',4,4' tetrahydroxybenzophenone (BP-2); 2-hydroxy-4-methoxybenzophenone (BP-3); 2,2' dihydroxy-4-methoxybenzophenone (BP-8) and 4-hydroxybenzophenone (4OH-BP) were measured by dispersive liquid-liquid microextraction and ultra-high performance liquid chromatography with tandem mass spectrometry detection. Semen quality was evaluated by measuring volume, sperm counts, motility and morphology. Serum samples were analyzed for reproductive hormones, including follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone (T), inhibin B and estradiol (E2). Associations between urinary concentrations of BP-type UV filters and semen quality parameters and reproductive hormone levels were examined using linear regression, adjusting for potential confounders. RESULTS: Ninety-seven percent of the men had detectable urinary concentrations of at least one of the five BP-type UV filters quantified. After adjustment for important covariates (body mass index, smoking status and time of blood sample collection), there was a significant positive association between urinary BP-1 and BP-3 concentrations and serum FSH levels (beta = 0.08, 95%CI: 0.009; 0.15 and beta = 0.04, 95%CI: 0.0002; 0.08, respectively). Urinary BP-1 concentration was also significantly positively associated with T/E2 (beta = 0.04, 95%CI: 0.002; 0.07) and negatively with inhibin b/FSH (beta = -0.11, 95%CI: -0.21; -0.006) ratio. No significant associations were found between other urinary BP-type UV filters and other reproductive hormone levels or between any semen parameters and any of the urinary BP-type UV filters quantified. CONCLUSIONS: Our results suggest that, in young men, urinary BP-type UV filters may be associated with a modest alteration of some reproductive hormones, but the effects we report on reproductive function are likely to be small, and of unclear clinical significance. Further research is needed to replicate these findings in other male populations. PMID- 29449082 TI - Multiple sclerosis or "inflammatory CADASIL?": Case Report and review of the literature. AB - BACKGROUND: Multiple sclerosis (MS) and CADASIL presenting together is exceedingly rare. As more cases of "inflammatory" CADASIL emerge, diagnostic challenges for clinicians increase. We report an individual with MS and CADASIL presenting with cognitive decline at age 25. She presented with gadolinium enhancing lesions on MRI and inflammatory cerebrospinal fluid raising the question of whether these patients should be given a diagnosis of "inflammatory CADASIL" or both MS and CADASIL. METHODS: A literature review was conducted on reports of inflammatory CADASIL or MS and CADASIL, clinical presentations including spinal cord lesions and CSF inflammatory markers. RESULTS: Nine cases in the literature of individuals with CADASIL and inflammatory presentations were found with treatment varying from intravenous steroids to MS immunomodulatory therapy. CONCLUSIONS: If individuals with CADASIL present with immune mediated inflammatory components they may benefit from immunomodulatory therapy. This is discussed with a review of the inflammatory CADASIL/MS cases in the literature and report of a case. PMID- 29449083 TI - Three-dimensional scapular dyskinesis in hook-plated acromioclavicular dislocation including hook motion. AB - BACKGROUND: The purpose of this study is to analyze the 3-dimensional scapular dyskinesis and the kinematics of a hook plate relative to the acromion after hook plated acromioclavicular dislocation in vivo. Reported complications of acromioclavicular reduction using a hook plate include subacromial erosion and impingement. However, there are few reports of the 3-dimensional kinematics of the hook and scapula after the aforementioned surgical procedure. METHODS: We studied 15 cases of acromioclavicular dislocation treated with a hook plate and 15 contralateral normal shoulders using computed tomography in the neutral and full forward flexion positions. Three-dimensional motion of the scapula relative to the thorax during arm elevation was analyzed using a computer simulation program. We also measured the distance from the tip of the hook plate to the greater tuberosity, as well as the angular motion of the plate tip in the subacromial space. RESULTS: Decreased posterior tilting (22 degrees +/- 10 degrees vs 31 degrees +/- 8 degrees ) in the sagittal plane and increased external rotation (19 degrees +/- 9 degrees vs 7 degrees +/- 5 degrees ) in the axial plane were evident in the affected shoulders. The mean values of translation of the hook plate and angular motion against the acromion were 4.0 +/ 1.6 mm and 15 degrees +/- 8 degrees , respectively. The minimum value of the distance from the hook plate to the humeral head tuberosity was 6.9 mm during arm elevation. CONCLUSIONS: Acromioclavicular reduction using a hook plate may cause scapular dyskinesis. Translational and angular motion of the hook plate against the acromion could lead to subacromial erosion. However, the hook does not seem to impinge directly on the humeral head.

AB - BACKGROUND: Paralabral cysts emanating from posterosuperior labral tears may compress the suprascapular nerve and induce neuropathy. This study prospectively assessed patients with labral tears and symptomatic paralabral cysts treated with isolated labral repair. Pain relief, time to cyst resolution, reversibility of muscular edema, atrophy, fatty infiltration, and bone erosion were evaluated. METHODS: Forty-seven patients with symptomatic posterosuperior paralabral cysts were treated with isolated labral repair. Magnetic resonance imaging (MRI) was repeated 6 and 12 weeks postoperatively or until cyst resolution. In a subgroup of 15 patients, MRI was performed the day before the operation, the first postoperative day, and at 2 weeks. RESULTS: Median cyst size was 6.8 cm3 (range, 2.1-88.9; standard deviation [SD], 18.3 cm3). Preoperatively, 20 patients (43%) presented clinical muscle atrophy and radiologic edema on MRI, 8 had fatty infiltration, and 3 presented bony scapular erosion caused by cyst compression. Median time to cyst resolution and regression of muscular edema was 11 weeks (range, 3-20; SD, 8.8 weeks) and 14 weeks (range, 3-52; SD 10.6 weeks), respectively. Preoperative fatty infiltration grade I and II of the supraspinatus and infraspinatus muscles was reduced in two patients. Bony erosions remodeled after cyst resolution. Mean pain ratings (1-10 scale) improved from 7.7 (SD, 1.8) to 1.3 (SD, 1.3; 95% confidence interval of difference, 5.5-6.8; P < .001). CONCLUSION: Labral repair leads to significant pain relief with cyst resolution within 2 to 3 months in most patients. Secondary muscle pathology (ie, edema, atrophy and fatty infiltration) may be partially or completely reversed. Bony erosion caused by cyst compression may be remodeled after cyst resolution.

AB - BACKGROUND: Adoptive transfer of donor-derived T cells can be applied to improve immune reconstitution in immune-compromised patients after allogeneic stem cell transplantation. The separation of beneficial T cells from potentially harmful T cells can be achieved by using the major histocompatibility complex (MHC) I Streptamer isolation technology, which has proven its feasibility for the fast and pure isolation of T-cell populations with a single specificity. We have analyzed the feasibility of the simultaneous isolation of multiple antigen specific T-cell populations in one procedure by combining different MHC I Streptamers. METHODS: First, the effect of combining different amounts of MHC I Streptamers used in the isolation procedure on the isolation efficacy of target antigen-specific T cells and on the number of off-target co-isolated contaminating cells was assessed. The feasibility of this approach was demonstrated in large-scale validation procedures targeting both high and low frequent T-cell populations using the Good Manufacturing Practice (GMP)-compliant CliniMACS Plus device. RESULTS: T-cell products targeting up to 24 different T cell populations could be isolated in one, simultaneous MHC I-Streptamer procedure, by adjusting the amount of MHC I- Streptamers per target antigen specific T-cell population. Concurrently, the co-isolation of potentially harmful contaminating T cells remained below our safety limit. This technology allows the reproducible isolation of high and low frequent T-cell populations. However, the expected therapeutic relevance of direct clinical application without in vitro expansion of these low frequent T-cell populations is questionable. DISCUSSION: This study provides a feasible, fast and safe method for the generation of highly personalized MHC I-Streptamer isolated T-cell products for adoptive immunotherapy.

AB - The field of tissue engineering is emerging as a multidisciplinary area with promising potential for regenerating new tissues and organs. This approach requires the involvement of three essential components: stem cells, scaffolds and growth factors. To date, dental pulp stem cells have received special attention because they represent a readily accessible source of stem cells. Their high plasticity and multipotential capacity to differentiate into a large array of tissues can be explained by its neural crest origin, which supports applications beyond the scope of oral tissues. Many isolation, culture and cryopreservation protocols have been proposed that are known to affect cell phenotype, proliferation rate and differentiation capacity. The clinical applications of therapies based on dental pulp stem cells demand the development of new biomaterials suitable for regenerative purposes that can act as scaffolds to handle, carry and implant stem cells into patients. Currently, the development of xeno-free culture media is emerging as a means of standardization to improve safe and reproducibility. The present review aims to describe the current knowledge of dental pulp stem cells, considering in depth the key aspects related to the characterization, establishment, maintenance and cryopreservation of primary cultures and their involvement in the multilineage differentiation potential. The main clinical applications for these stem cells and their combination with several biomaterials is also covered.

AB - 3A2g->3T1g(P) transition band of Ni2+ is used to probe the coordination of Ni2+. Two-dimensional asynchronous spectra (2DCOS) are generated using the Double Asynchronous Orthogonal Sample Design (DAOSD), Asynchronous Spectrum with Auxiliary Peaks (ASAP) and Two-Trace Two-Dimensional (2T2D) approaches. Cross peaks relevant to the 3A2g->3T1g(P) transition band of Ni2+ are utilized to probe coordination between Ni2+ and various ligands. We studied the spectral behavior of the 3A2g->3T1g(P) transition band when Ni2+ is coordinated with ethylenediaminetetraacetic acid disodium salt (EDTA). The pattern of cross peaks in 2D asynchronous spectrum demonstrates that coordination brings about significant blue shift of the band. In addition, the absorptivity of the band increases remarkably. The interaction between Ni2+ and galactitol is also investigated. Although no clearly observable change is found on the 3A2g->3T1g(P) transition band when galactitol is introduced, the appearance of cross peak in 2D asynchronous spectrum demonstrates that coordination indeed occurs between Ni2+ and galactitol. Furthermore, the pattern of cross peak indicates that peak position, bandwidth and absorptivity of the 3A2g->3T1g(P) transition band of Ni(galactitol)x2+ is considerably different from those of Ni(H2O)62+. Thus, 2DCOS is helpful to reveal subtle spectral variation, which might be helpful in shedding light on the physical-chemical nature of coordination. PMID- 29449088 TI - Temperature Modulates Tissue-Specification Program to Control Fruit Dehiscence in Brassicaceae. AB - Plants respond to diurnal and seasonal changes in temperature by reprogramming vital developmental pathways. Understanding the molecular mechanisms that define environmental modulation of plant growth and reproduction is critical in the context of climate change that threatens crop yield worldwide. Here, we report that elevated temperature accelerates fruit dehiscence in members of the Brassicaceae family including the model plant Arabidopsis thaliana and important crop species. Arabidopsis fruit development is controlled by a network of interacting regulatory genes. Among them, the INDEHISCENT (IND) gene is a key regulator of the valve-margin tissue that mediates fruit opening, hence facilitating fruit dehiscence. We demonstrated that the valve-margin development is accelerated at higher temperature and that IND is targeted for thermosensory control. Our results reveal that IND upregulation is facilitated via temperature induced chromatin dynamics leading to accelerated valve-margin specification and dispersal of the seed. Specifically, we show that temperature-induced changes in IND expression are associated with thermosensory H2A.Z nucleosome dynamics. These findings establish a molecular framework connecting tissue identity with thermal sensing and set out directions for the production of temperature-resilient crops.

AB - Long non-coding RNAs (lncRNAs) are currently recognized as crucial players in nervous system development, function and pathology. In Amyotrophic Lateral Sclerosis (ALS), identification of causative mutations in FUS and TDP-43 or hexanucleotide repeat expansion in C9ORF72 point to the essential role of aberrant RNA metabolism in neurodegeneration. In this study, by taking advantage of an in vitro differentiation system generating mouse motor neurons (MNs) from embryonic stem cells, we identified and characterized the long non-coding transcriptome of MNs. Moreover, by using mutant mouse MNs carrying the equivalent of one of the most severe ALS-associated FUS alleles (P517L), we identified lncRNAs affected by this mutation. Comparative analysis with human MNs derived in vitro from induced pluripotent stem cells indicated that candidate lncRNAs are conserved between mouse and human. Our work provides a global view of the long non-coding transcriptome of MN, as a prerequisite toward the comprehension of the still poorly characterized non-coding side of MN physiopathology. PMID- 29449090 TI - Clinical and Molecular Characteristics and Burden of Kidney Cancer Among Hispanics and Native Americans: Steps Toward Precision Medicine. AB - Cancer disparities in Native Americans (NAs) and Hispanic Americans (HAs) vary significantly in terms of cancer incidence and mortality rates across geographic regions. This review reports that kidney and renal pelvis cancers are unevenly affecting HAs and NAs compared to European Americans of non-Hispanic origin, and that currently there is significant need for improved data and reporting to be able to advance toward genomic-based precision medicine for the assessment of such cancers in these medically underserved populations. More specifically, in states along the US-Mexico border, HAs and NAs have higher kidney cancer incidence rates as well as a higher prevalence of kidney cancer risk factors, including obesity and chronic kidney disease. They are also more likely to receive suboptimal care compared to European Americans. Furthermore, they are underrepresented in epidemiologic, clinical, and molecular genomic studies of kidney cancer. Therefore, we maintain that progress in precision medicine for kidney cancer care requires an understanding of various factors among HAs and NAs, including the real kidney cancer burden, variations in clinical care, issues related to access to care, and specific clinical and molecular characteristics. PMID- 29449091 TI - Adjuvant Therapies in Nonmetastatic Renal-Cell Carcinoma: A Review of the Literature. AB - To conduct a review of literature on adjuvant therapy in nonmetastatic renal-cell carcinoma (nmRCC) treated with nephrectomy and to describe the efficacy of adjuvant agents on cancer control outcomes. A review of the literature was performed in January 2018 to identify all studies evaluating adjuvant therapy in patients with nmRCC treated with nephrectomy using PubMed, Embase, Medline, and Cochrane Library databases. The following keywords were used: adjuvant therapy, renal-cell carcinoma, nonmetastatic, targeted molecular therapy, kidney cancer. The ClinicalTrials.gov website was queried to identify ongoing trials. Traditional adjuvant therapy agents consisted of interferon alpha, interleukin 2, autologous tumor cell vaccines, and monoclonal antibodies. None provided survival benefit. Three contemporary studies (S-TRAC, ASSURE, and PROTECT) using targeted therapy compared sunitinib to placebo (S-TRAC), sunitinib or sorafenib to placebo (ASSURE), and pazopanib to placebo (PROTECT), with controversial results. In contrast to ASSURE and PROTECT, S-TRAC demonstrated improved disease-free survival. Several trials that use checkpoint immunotherapy agents or vascular endothelial growth factor receptor tyrosine kinase inhibitors are ongoing. Many traditional therapies have shown no success as adjuvant therapy for nmRCC after nephrectomy. Targeted adjuvant therapy for nmRCC after nephrectomy showed controversial results, and its routine use is not currently endorsed. PMID- 29449092 TI - Efficacy of narrow-band imaging for detecting intestinal metaplasia in adult patients with symptoms of dyspepsia. AB - INTRODUCTION AND OBJECTIVE: Atrophy and intestinal metaplasia are early phenotypic markers in gastric carcinogenesis. White light endoscopy does not allow direct biopsy of intestinal metaplasia due to a lack of contrast of the mucosa. Narrow-band imaging is known to enhance the visibility of intestinal metaplasia, to reduce sampling error, and to increase the diagnostic yield of endoscopy for intestinal metaplasia in Asian patients. The aim of our study was to validate the diagnostic performance of narrow-band imaging using 1.5* electronic zoom endoscopy (with no high magnification) to diagnose intestinal metaplasia in Mexican patients. MATERIALS AND METHODS: A retrospective cohort study was conducted on consecutive patients with dyspeptic symptoms at a private endoscopy center within the time frame of January 2015 to December 2016. RESULTS: A total of 338 patients (63+/-8.4 years of age, 40% women) were enrolled. The prevalence of H. pylori infection was 10.9% and the incidence of intestinal metaplasia in the gastric antrum and corpus was 23.9 and 5.9%, respectively. Among the patients with intestinal metaplasia, 65.3% had the incomplete type, 42.7% had multifocal disease, and one third had extension to the gastric corpus. Two patients had low-grade dysplasia. The sensitivity of white light endoscopy was 71.2%, with a false negative rate of 9.9%. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of narrow-band imaging (with a positive light blue crest) were 85, 98, 86.8, 97.7, and 87.2%, respectively. CONCLUSION: The prevalence of H. pylori infection and intestinal metaplasia in dyspeptic Mexican patients was not high. Through the assessment of the microsurface structure and light blue crest sign, non-optical zoom narrow band imaging had high predictive values for detecting intestinal metaplasia in patients from a general Western setting.

PMID- 29449094 TI - Safety and efficacy of small bowel polypectomy using a balloon-assisted enteroscope in pediatric patients with Peutz-Jeghers syndrome. AB - INTRODUCTION AND AIMS: Peutz-Jeghers syndrome is an autosomal dominant inherited pathology characterized by gastrointestinal hamartomatous polyps, predominantly in the small bowel, and pigmented mucocutaneous lesions. Guidelines suggest polypectomy with a balloon-assisted enteroscope when polyps are larger than 10mm. Complications in adults can be as high as 6.8%, but there is little information on pediatric populations. Our aim was to describe the safety and efficacy of polypectomy in a group of pediatric patients with Peutz-Jeghers syndrome using balloon-assisted enteroscopy. MATERIALS AND METHODS: A retrospective study was conducted at the Hospital de Especialidades del Centro Medico Nacional Siglo XXI on pediatric patients with Peutz-Jeghers syndrome that required balloon-assisted enteroscopy and polypectomy within the time frame of January 2010 and December 2015. Patients that underwent polypectomy with a push enteroscope were excluded from the study. RESULTS: A total of 35 polypectomies were performed on 4 patients (female/male: 3/1). The mean age of the patients was 13.7 years (range:11-16). Twelve enteroscopies were carried out, 8 of which were anterograde. A single balloon enteroscope was used in 7 procedures and a double-balloon enteroscope in 5. The mean size of the polyps was 1.6cm (range: 1-4cm). A major complication (acute pancreatitis) presented in only one case (8.3%). No other major complications associated with the procedures were observed. CONCLUSION: Balloon assisted enteroscopy with polypectomy in children is a safe and effective procedure, with complications similar to those reported in adults. PMID- 29449096 TI - Evaluating the Impact of Diabetes Self-Management Education Methods on Knowledge, Attitudes and Behaviours of Adult Patients With Type 2 Diabetes Mellitus. AB - OBJECTIVES: Diabetes self-management refers to all activities patients undertake to care for their illness, promote health and prevent the long- and short-term effects of diabetes. This study compared the effectiveness of 2 diabetes self management education methods by examining changes in glycated hemoglobin (A1C) levels and knowledge, attitudes and behaviours (KABs) after traditional group education (TE) or with diabetes conversation maps (CMs). The CMs group was postulated to show greater decrease in A1C levels and improved KABs scores compared to the TE group. METHODS: A sample of 21 eligible clients from Diabetes Care Guelph were randomly assigned into 2 groups: 10 receiving education through CMs and 11 through TE. Changes in knowledge and attitude were determined by using questionnaires and repeated-measures pretest and post-test design before and after the education sessions. Changes in A1C levels were determined by comparing values at baseline and at 3 months after receiving diabetes education. Two focus groups were conducted to obtain participants' perceptions of the education methods and self-reported KAB changes. RESULTS: Significant differences in knowledge and attitude score changes were observed from baseline/initial education and after 3 months. Both groups had significant decreases in A1C levels from baseline to 3 months afterward. Focus groups revealed themes common to both groups, such as benefits of early education, the need for multiple lifestyle behaviour changes and feelings about social support. CONCLUSIONS: CMs had a significant impact and are effective for group education. The changes observed may lead to improved diabetes self-management, thus reducing costly health complications related to poorly controlled diabetes. PMID- 29449095 TI - Relationships between bacteriospermia, DNA integrity, nuclear protamine alteration, sperm quality and ICSI outcome. AB - : The Aim of this study was to evaluate the effects of bacteriospermia on human sperm parameters, nuclear protamines, DNA integrity and ICSI outcome in patients enrolled for ICSI treatment. 84 unselected couples consulting in infertility and obstetrics clinic and enrolled for ICSI treatment were included in this study. The semen specimens were screened bacteriologically; semen and sperm parameters were also evaluated according to WHO guidelines. DNA integrity, protamines concentration and protamine deficiency were estimated by TUNEL assay, AU-PAGE and Chromomycin (CMA3) respectively. The results of this study revealed that 34.52% of studied semen samples were infected with bacteria. The isolated bacteria were identified as Staphylococcus aureus, Staph. epidermidis, Staph. haemolyticus, Escherichia coli, Enterococcus faecalis and Streptococcus agalactiae. Bacteriospermia had a significant (p < .010) negative effect on sperm parameters; concentration, motility, progressive motility and chromatin condensation. Moreover, high DNA fragmentation with low P1 and P2 concentrations were noticed in infected patients in comparison to non-infected patients but non-significant. Also, the fertilization rate decreased significantly (p < .05) with infected patients. IN CONCLUSION: bacteriospermia has significant negative effect on sperm quality and fertilization rate in patients who underwent ICSI treatment. PMID- 29449097 TI - 'The Unhealthy Other': How vaccine rejecting parents construct the vaccinating mainstream. AB - To address the phenomenon of vaccine hesitancy and rejection, researchers increasingly recognise the need to engage with the social context of parents' decision-making. This study examines how vaccine rejecting parents socially construct the vaccinating mainstream in opposition to themselves. We analyse qualitative data from interviews with parents in Adelaide, South Australia. Applying insights from Social Identity Theory (SIT), we show how these parents bolster their own sense of identity and self-belief by employing a discourse that casts vaccinators as an Unhealthy Other. We demonstrate how the parents identify vaccination as a marker of parental conformity to the 'toxic practices of mass industrial society', linking it to other ways in which membership of the consumerist mainstream requires individuals to 'neglect their health.' This is explored through themes of appearance, diet, (over) consumption of pharmaceuticals, inadequate parenting values and wilful or misguided ignorance. This construction of the Unhealthy Other elevates the self-concept of vaccine hesitant and rejecting parents, who see themselves as part of an enlightened, but constantly besieged, group of healthy and virtuous parents. It is common for the vaccinating mainstream to present vaccine hesitant and rejecting parents as a group subject to epistemic closure, groupthink, confirmation bias and over confidence in their own expertise. However, vaccine hesitant and rejecting parents also see mainstream society as a group-a much larger one-subject to the same problems. We suggest the need to mitigate the 'groupness' of vaccination and non-vaccination by extending the practice of vaccination to recognisable practitioners of holistic health. PMID- 29449098 TI - Quantification of human complement factor H binding to asexual malaria blood stages by an enzyme-linked immunosorbent assay. AB - The human complement system is the most effective defense mechanism of the human innate immune system. One major negative regulator of the alternative pathway in human blood is complement factor H (FH). It binds to autologous cells and thus, prevents complement attack against body-cells or tissues. Various pathogens are known to escape complement recognition by recruiting FH to provide protection against the host's immune system. This immune evasion mechanism was recently qualitatively reported for asexual malaria blood stages. To indirectly evaluate the stage-specific potential of FH-receptor proteins as vaccine candidates, we quantified the FH molecules bound to the surface of different malaria blood stage parasites by Western blot and a commercially available FH-ELISA, which was originally designed to measure the FH concentration in human serum. Host-cell free merozoites and intracellular mature schizont (here called segmenter) stages bind significantly more FH molecules than earlier parasite stages. PMID- 29449099 TI - Cost of goods sold and total cost of delivery for oral and parenteral vaccine packaging formats. AB - Despite limitations of glass packaging for vaccines, the industry has been slow to implement alternative formats. Polymer containers may address many of these limitations, such as breakage and delamination. However, the ability of polymer containers to achieve cost of goods sold (COGS) and total cost of delivery (TCOD) competitive with that of glass containers is unclear, especially for cost sensitive low- and lower-middle-income countries. COGS and TCOD models for oral and parenteral vaccine packaging formats were developed based on information from subject matter experts, published literature, and Kenya's comprehensive multiyear plan for immunization. Rotavirus and inactivated poliovirus vaccines (IPV) were used as representative examples of oral and parenteral vaccines, respectively. Packaging technologies evaluated included glass vials, blow-fill-seal (BFS) containers, preformed polymer containers, and compact prefilled auto-disable (CPAD) devices in both BFS and preformed formats. For oral vaccine packaging, BFS multi-monodose (MMD) ampoules were the least expensive format, with a COGS of $0.12 per dose. In comparison, oral single-dose glass vials had a COGS of $0.40. BFS MMD ampoules had the lowest TCOD of oral vaccine containers at $1.19 per dose delivered, and ten-dose glass vials had a TCOD of $1.61 per dose delivered. For parenteral vaccines, the lowest COGS was achieved with ten-dose glass vials at $0.22 per dose. In contrast, preformed CPAD devices had the highest COGS at $0.60 per dose. Ten-dose glass vials achieved the lowest TCOD of the parenteral vaccine formats at $1.56 per dose delivered. Of the polymer containers for parenteral vaccines, BFS MMD ampoules achieved the lowest TCOD at $1.89 per dose delivered, whereas preformed CPAD devices remained the most expensive format, at $2.25 per dose delivered. Given their potential to address the limitations of glass and reduce COGS and TCOD, polymer containers deserve further consideration as alternative approaches for vaccine packaging. PMID- 29449101 TI - Evaluation of a convenient vaccination schedule against hepatitis B in HIV patients with undetectable HIV viral load. AB - Vaccination against hepatitis B virus (HBV) is recommended for all HIV-positive individuals but the standard schedule is not satisfactory. High or more doses have also been studied with variable results. We compared a vaccination schedule with a higher dose but fewer shots to the standard scheme (HBVaxPro 40 MUg versus Engerix 20 MUg at 0, 1, and 6 months). Of the 63 patients vaccinated with HBVaxPro 79%, 65% and 47% seroconverted at month 1, 12 and 24 after vaccination, respectively. A total of 137 patients received Engerix and showed lower response rates (68%, 53% and 38%, respectively). Anti-HBs titers in the Engerix group were also lower with a statistically significant difference. In patients younger than 55 years HBVaxPro was 3 times more likely to provoke a response compared with Engerix (OR = 3, p = 0.006). In conclusion, HBVaxPro 40 MUg at 3 doses could be proposed as a more robust and acceptable alternative. PMID- 29449100 TI - Hepatitis A vaccination coverage among adolescents (13-17 years) in the United States, 2008-2016. AB - BACKGROUND: The hepatitis A (HepA) vaccine was recommended by the Advisory Committee on Immunization Practices (ACIP) incrementally from 1996 to 1999. In 2006, HepA vaccine was recommended (1) universally for children aged 12-23 months, (2) for persons who are at increased risk for infection, or (3) for any person wishing to obtain immunity. Catch-up vaccination can be considered. OBJECTIVE: To assess HepA vaccine coverage among adolescents and factors independently associated with vaccination administration in the US. METHODS: The 2008-2016 National Immunization Survey-Teen was utilized to determine 1 and >=2 dose HepA vaccination coverage among adolescents aged 13-17 years. Factors associated with HepA vaccine series initiation (1 dose) were determined by bivariate and multivariable analyses. Data were stratified by state groups based on ACIP recommendation: universal child vaccination recommended since 1999 (group 1); child vaccination considered since 1999 (group 2); universal child vaccination recommendation since 2006 (group 3). RESULTS: In 2016, national vaccination coverage for 1 and >=2 doses of HepA vaccine among adolescents was 73.9% and 64.4%, respectively. Nationally, a 40 percentage point increase in vaccination coverage occurred among adolescents born in 1995 compared to adolescents born in 2003. Nationally, the independent factors associated with increased vaccine initiation was race/ethnicity (Hispanic, American Indian/Alaskan Native, Asian), military payment source and provider recommendation for HepA vaccination (2008-2013). Living in a suburban or rural region, living in poverty (level <1.33-5.03), and absence of state daycare or school HepA requirement were common factors associated with decreased likelihood of vaccine initiation. CONCLUSIONS: Efforts to increase HepA vaccine coverage in adolescents in all regions of the country would strengthen population protection from hepatitis A virus (HAV). PMID- 29449103 TI - Calcitonin and Omega-3 Fatty Acids Exhibit Antagonistic and Non-Additive Effects in Experimental Diabetes. AB - Because optimising therapy for the management of diabetes mellitus remains challenging, the study investigated the effects of salmon calcitonin (Sct) and/or omega-3 fatty acids (N-3 - eicosapentaenoic acid and docosahexaenoic acid-3:2), compared to metformin, on selected biochemical parameters in male Wistar rats, in an experimental model of diabetes. Forty rats were used for this study. They were divided into eight groups of five rats each, which included: Normal control; Diabetic (D) control; D + N-3; D + low dose Sct (Sct. Lw); D + high dose Sct (Sct. Hi); D + N-3 + Sct.Lw; D + N-3 + Sct.Hi; and D + metformin. Diabetes was induced in overnight fasted rats by the administration of streptozotocin (65 mg/kg b.w., i.p.), 15 min after the administration of nicotinamide (110 mg/kg b.w., i.p.). Nine days later, Sct was administered at 2.5 and 5.0 IU/kg b.w./day (i.m.), while N-3 and metformin were administered at 200 and 180 mg/kg b.w./day (p.o.) respectively, for four weeks. Sct, N-3, and metformin significantly reduced total cholesterol, LDL-C, cortisol, c-telopeptide of type 1 collagen, and collagen type 2 alpha-1. The combined administration of Sct and N-3 had more favorable effects on triglyceride and HDL-C than either monotherapy. Unlike metformin and Sct. Hi, N-3 significantly reduced alkaline phosphatase activity. Moreover, N-3 significantly suppressed the hypocalcaemic, hyperglycaemic, and insulin resistance provoking actions of Sct. Furthermore, N-3 contradicted the hepatic glycogen depletion and inhibition of nitric oxide synthesis brought about by Sct. In conclusion, N-3 demonstrated antagonistic and non-additive actions with Sct. Moreover, the effects of the combined administration of Sct and N-3 were comparable to that of metformin; therefore, they might be considered as therapeutic alternatives in diabetes. PMID- 29449102 TI - Anterosuperior anchoring myringoplasty using cyanoacrylate glue can prevent packing gelfoam in the middle ear cavity. AB - OBJECTIVES: Although a number of methods have been attempted to improve securing the graft, packing gelfoam in the middle ear cavity cannot be avoided, which could obstruct the tympanic ostium of the Eustachian tube and affect inner ear function. Myringoplasty using tissue adhesive has gained traction because tissue adhesives can effectively stabilise the graft and act as scaffolding to improve the graft uptake. The aim of this prospective study was to explore myringoplasty using cyanoacrylate glue with no packing in the middle ear cavity for the repair of subtotal tympanic membrane (TM) perforations. METHODS: Between March 2014 and November 2015, 71 patients with subtotal TM perforations were randomly and prospectively divided into a glue group and a control group. Two securing techniques were performed using only cyanoacrylate glue or using only filling gelfoam in the middle ear cavity, respectively, during an anterosuperior anchoring myringoplasty operated by a single surgeon. RESULTS: At a 6-month follow-up, the graft uptake rate was 87% in the glue group and 89% in the control group. A significant hearing improvement was found in both groups postoperatively when compared to the preoperative values (P<0.05 for both). There was no significant difference in the graft uptake rate and hearing improvement between the 2 groups (P>0.05). Similar complications were found in each group. CONCLUSION: Cyanoacrylate glue is a helpful material for graft stabilisation and can substitute for filling gelfoam in the middle ear cavity during anterosuperior anchoring myringoplasty for subtotal TM perforation.

A characterisation of sellers and buyers over time. AB - INTRODUCTION: Cryptomarkets operating on the darknet are a recent phenomenon that has gained importance only over the last couple of years (Barratt, 2012). However, they now constitute an evolving part of illicit drug markets. Although selling and buying a variety of psychoactive substances on the Internet has a long history, new technological developments enable systematic drug trading on the net.These technological innovations on the Internet allow users to proceed with (illicit) drug transactions with almost completely anonymous identities and locations. In this paper, we provide a systematic measurement analysis of structures and trends on the most popular anonymous drug marketplace, and discuss the role of cryptomarkets in drug distribution. METHODS: Data collection and analysis include a long-term measurement of the cryptomarket 'AlphaBay', the most popular platform during the survey period. By developing and applying a web scraping tool, market data was extracted from the marketplace on a daily basis during a period of twelve months between September 2015 and August 2016. The data was analysed by using business-intelligence software, which allows the linking of various data sets. We found 2188 unique vendors offering 11,925 drug items. The findings of our long-term monitoring and data analysis are compared over time and across marketplaces, offering a detailed understanding of the development of revenues generated, characterisation of countries of origin and destination, and distribution of vendors and customers over time. RESULTS: We provide a nuanced and highly detailed longitudinal analysis of drug trading on the darknet marketplace 'AlphaBay', which was the largest cryptomarket in operation. 1) Total sales volumes for the 'drugs' section was estimated at approximately USD 94 million for the period from September 2015 to August 2016. 2) In addition, about 64% of all sales are made with cocaine-, cannabis-, heroin-, and ecstasy-related products. 3) Average selling prices increase over time for categories including cannabis and hashish, ecstasy, opioids, psychedelics and stimulants. 4) The five most frequent countries of origin as indicated by vendors are the United States, United Kingdom, Australia, the Netherlands and Germany. Moreover, it was demonstrated that drug distribution on cryptomarkets is conducted at a regional rather than global level. 6) Furthermore, 4.88% of vendors made over USD 200,000 and were responsible for 52.9% of total revenues generated over the period analysed. In contrast, 57.51% of vendors managed to sell drug items worth less than USD 10,000 within a period of twelve months. The findings suggest that 'AlphaBay' was a cryptomarket mainly from and for Western industrialised countries. In contrast, countries of the global South are neither among the main countries of origin nor destination countries.

Segmental hair analysis may differentiate a single exposure from chronic use. Consequently, segmental hair analysis is useful for disclosing a single drug ingestion, as well as for determining repeated exposures in drug-facilitated crimes (DFCs). This paper presents an overview of toxicological investigations that have used hair analysis in DFC cases from 2009 to 2016 in Denmark. Hair concentrations were determined for 24 DFC-related drugs and metabolites, including benzodiazepines and other hypnotics, antihistamines, opioid analgesics, antipsychotics, barbiturates, and illicit drugs from DFC cases. Drug detection in hair in DFC cases following a single or few intakes of chlorprothixene, codeine, diphenhydramine, oxazepam, oxycodone, promethazine, and phenobarbital is reported for the first time in forensic toxicology. A literature review on concentrations in the published DFC-related hair cases and on concentrations in hair of these substances after single and multiple doses is included. These cases demonstrate the value of segmental hair analysis in DFCs and facilitate future interpretations of results. PMID- 29449107 TI - A Model for Manganese interaction with Deinococcus radiodurans proteome network involved in ROS response and defense. AB - A complex network of regulatory proteins takes part in the mechanism underlying the radioresistance of Deinoccocus radiodurans bacterium (DR). The interaction of Mn(II) ions with DR-proteins and peptides seems to be responsible for proteins protection from oxidative damage induced by Reactive Oxygen Species during irradiation. In the present work we describe a combined approach of bioinformatic strategies based on structural data and annotation to predict the Mn(II)-binding proteins encoded by the genome of DR and, in parallel, the same predictions for other bacteria were performed; the comparison revealed that, in most of the cases, the content of Mn(II)-binding proteins is significantly higher in radioresistant than in radiosensitive bacteria. Moreover, we report the in silico protein-protein interaction network of the putative Mn(II)-proteins, remodeled in order to enhance the knowledge about the impact of Mn-binding proteins in DR ability to protect also DNA from various damaging agents such as ionizing radiation, UV radiation and oxidative stress. PMID- 29449108 TI - Effect of nitrogen and zinc fertilization on zinc and iron bioavailability and chemical speciation in maize silage. AB - Agronomic biofortification is one of the main strategies for alleviation of micronutrient deficiencies in food and feed. The objective of this study was to investigate the effect of N supply on total concentration of Zn and Fe and their chemical species in the soluble extracts of maize silage grown under field conditions. Total concentrations of Zn, Fe, Cu, Mn, S and P were measured by flow injection inductive coupled plasma (ICP) - mass spectrometer (MS). Soluble Fe and Zn were extracted and analyzed by size exclusion-inductively coupled plasma mass spectrometry. Using the same set-up for total elemental and speciation analysis enabled direct quantitative comparison of the detected speciated molecules with the total element sample content. N or Zn treatment, except in control plots, did not significantly affect concentrations of Zn and Fe in the maize silage and grain samples. Significant positive correlation was observed between Zn and Fe maize silage (r = 0.64, p < 0.01) and maize grain (r = 0.85, p < 0.01) concentrations. N and Zn treatment did not affect solubility of Zn and Fe, while available Zn and Fe were affected by increase in Zn soil treatment. Soluble Zn was speciated in LMW complexes, while soluble Fe was speciated in MMW and LMW complexes. PMID- 29449109 TI - Arsenic-containing hydrocarbons disrupt a model in vitro blood-cerebrospinal fluid barrier. AB - Lipid-soluble arsenicals, so-called arsenolipids, have gained a lot of attention in the last few years because of their presence in many seafoods and reports showing substantial cytotoxicity emanating from arsenic-containing hydrocarbons (AsHCs), a prominent subgroup of the arsenolipids. More recent in vivo and in vitro studies indicate that some arsenolipids might have adverse effects on brain health. In the present study, we focused on the effects of selected arsenolipids and three representative metabolites on the blood-cerebrospinal fluid barrier (B CSF-B), a brain-regulating interface. For this purpose, we incubated an in vitro model of the B-CSF-B composed of porcine choroid plexus epithelial cells (PCPECs) with three AsHCs, two arsenic-containing fatty acids (AsFAs) and three representative arsenolipid metabolites (dimethylarsinic acid, thio/oxo dimethylpropanoic acid) to examine their cytotoxic potential and impact on barrier integrity. The toxic arsenic species arsenite was also tested in this way and served as a reference substance. While AsFAs and the metabolites showed no cytotoxic effects in the conducted assays, AsHCs showed a strong cytotoxicity, being up to 1.5-fold more cytotoxic than arsenite. Analysis of the in vitro B-CSF B integrity showed a concentration-dependent disruption of the barrier within 72 h. The correlation with the decreased plasma membrane surface area (measured as capacitance) indicates cytotoxic effects. These findings suggest exposure to elevated levels of certain arsenolipids may have detrimental consequences for the central nervous system. PMID- 29449110 TI - Impact of meteorological parameters on extracted landfill gas composition and flow. AB - The objective of this study was to investigate the impact of four pre-selected meteorological parameters (barometric pressure, wind speed, ambient temperature and solar radiation) on recovered landfill gas (LFG) flow, methane (CH4) content of the LFG and the recovered CH4 flow by performing statistical correlation tests and a visual check on correlations in scatterplots. Meteorological parameters were recorded at an on-site weather station, while LFG data were recorded when entering the gas engine. LFG CH4 concentration, LFG flow and CH4 flow correlated highly with both barometric pressure and changes in barometric pressure, and the correlations were statistically significant. A higher correlation was observed when studying changes in barometric pressure in comparison to the absolute value of barometric pressure. LFG recovery data correlated highly and significantly with wind speed during winter, but not during summer. Ambient temperature and solar radiation were not major meteorological parameters affecting LFG recovery, as low correlation coefficients were observed between these two parameters and the LFG recovery data. PMID- 29449111 TI - A comparative study of thermophilic and mesophilic anaerobic co-digestion of food waste and wheat straw: Process stability and microbial community structure shifts. AB - Renewable energy recovery from organic solid waste via anaerobic digestion is a promising way to provide sustainable energy supply and eliminate environmental pollution. However, poor efficiency and operational problems hinder its wide application of anaerobic digestion. The effects of two key parameters, i.e. temperature and substrate characteristics on process stability and microbial community structure were studied using two lab-scale anaerobic reactors under thermophilic and mesophilic conditions. Both the reactors were fed with food waste (FW) and wheat straw (WS). The organic loading rates (OLRs) were maintained at a constant level of 3 kg VS/(m3.d). Five different FW:WS substrate ratios were utilized in different operational phases. The synergetic effects of co-digestion improved the stability and performance of the reactors. When FW was mono digested, both reactors were unstable. The mesophilic reactor eventually failed due to volatile fatty acid accumulation. The thermophilic reactor had better performance compared to mesophilic one. The biogas production rate of the thermophilic reactor was 4.9-14.8% higher than that of mesophilic reactor throughout the experiment. The shifts in microbial community structures throughout the experiment in both thermophilic and mesophilic reactors were investigated. With increasing FW proportions, bacteria belonging to the phylum Thermotogae became predominant in the thermophilic reactor, while the phylum Bacteroidetes was predominant in the mesophilic reactor. The genus Methanosarcina was the predominant methanogen in the thermophilic reactor, while the genus Methanothrix remained predominant in the mesophilic reactor. The methanogenesis pathway shifted from acetoclastic to hydrogenotrophic when the mesophilic reactor experienced perturbations. Moreover, the population of lignocellulose-degrading microorganisms in the thermophilic reactor was higher than those in mesophilic reactor, which explained the better performance of the thermophilic reactor. PMID- 29449112 TI - Production of an innovative biowaste-derived fertilizer: Rapid monitoring of physical-chemical parameters by hyperspectral imaging. AB - In this work the possibility to apply hyperspectral imaging as a fast and non destructive technique for the monitoring of the production process at pilot plant scale of an innovative biowaste-derived fertilizer was explored. Different mixtures of urban organic waste, farm organic residues, biochar and vegetable active principles were selected and utilized in two different European countries, Italy and Spain, for the production of the innovative fertilizer. The biowaste derived fertilizer samples were collected from the pilot plant piles at different curing time and acquired by the hyperspectral imaging device. Spectra have been collected in the near infrared wavelength range (1000-1700 nm). Conventional analyses were carried out on the same samples in order to find correlations between the physical-chemical parameters detected at laboratory scale, and the acquired reflectance spectra. The investigated parameters were: pH, electrical conductivity, soluble total organic carbon and soluble total nitrogen. Hyperspectral data were processed adopting chemometric strategies through the application of principal component analysis, for exploratory purposes, and partial least squares analysis to establish correlations between spectral features and measured physical-chemical parameters. Good correlations, with R2 ranging between 0.85 and 0.96, were obtained for all the investigated parameters. Results showed as the proposed approach, based on hyperspectral imaging, is suitable to be adopted for a rapid and non-destructive monitoring of waste derived fertilizer production. PMID- 29449113 TI - Characterization of the non-metal fraction of the processed waste printed circuit boards. AB - Electronic waste is one the fastest growing waste streams in the world and waste printed circuit boards (PCB) are the most valuable part of this stream due to the presence of gold, silver, copper, and palladium. The metal present in PCBs is mostly recovered for the market value whereas the nonmetal fractions are often ignored. This research explored the characteristics of the non-metal fraction (NMF) obtained after the processing of milled waste PCBs with a focus on responsible end-of-life solutions, in the form of non-hazardous landfilling or incineration. The NMF was characterized using sizing, assaying, loss on ignition, calorific value measurement, and thermogravimetric analysis (TGA). The result showed that the metal content in the NMF increased with decrease in the particle size for most of the metals except antimony and the result from loss on ignition (LOI) also showed that over 50% of the coarser fraction represented organic matter compared to less than 30% for the finest fraction. The study also showed that after the recovery of metals from the waste PCBs, landfill leaching for most of the metal is reduced below the environmental limits, with lead being the only exception. The lead leachate concentration of 18 mg/L was observed, which requires further treatment prior to landfilling. With an energy value of 16 GJ/t, the NMF could provide high energy recovery if incinerated but 194 mg/kg of hazardous flame retardants present in the NMF might be released if the combustion process is not closely monitored. PMID- 29449114 TI - Role of rain intensity and soil colloids in the retention of surfactant stabilized silver nanoparticles in soil. AB - Undisturbed outdoor lysimeters containing arable loamy sand soil were used to examine the influence of either heavy rain events (high frequency of high rain intensity), steady rain (continuous rainfall of low rain intensity), and natural rainfall on the transport and retention of surfactant-stabilized silver nanoparticles (AgNP). In addition, the AgNP-soil associations within the Ap horizon were analyzed by means of particle-size fractionation, asymmetrical flow field-flow fractionation coupled with UV/Vis-detection and inductively coupled plasma mass spectrometer (AF4-UV/Vis-ICP-MS), and transmission electron microscopy coupled to an energy-dispersive X-ray (TEM-EDX) analyzer. The results showed that AgNP breakthrough for all rain events was less than 0.1% of the total AgNP mass applied, highlighting that nearly all AgNP were retained in the soil. Heavy rain treatment and natural rainfall revealed enhanced AgNP transport within the Ap horizon, which was attributed to the high pore water flow velocities and to the mobilization of AgNP-soil colloid associations. Particle-size fractionation of the soil revealed that AgNP were present in each size fraction and therefore indicated strong associations between AgNP and soil. In particular, water-dispersible colloids (WDC) in the size range of 0.45-0.1 MUm were found to exhibit high potential for AgNP attachment. The AF4-UV/Vis-ICP-MS and TEM-EDX analyses of the WDC fraction confirmed that AgNP were persistent in soil and associated to soil colloids (mainly composed of Al, Fe, Si, and organic matter). These results confirm the particularly important role of soil colloids in the retention and remobilization of AgNP in soil. Furthermore, AF4-UV/Vis-ICP-MS results indicated the presence of single, homo-aggregated, and small AgNP probably due to dissolution. PMID- 29449115 TI - Single and combined effects of microplastics and mercury on juveniles of the European seabass (Dicentrarchus labrax): Changes in behavioural responses and reduction of swimming velocity and resistance time. AB - Microplastics and mercury are environmental pollutants of great concern. The main goal of the present study was to investigate the effects of these pollutants, both individually and in binary mixtures, on the swimming performance of juvenile European seabass, Dicentrarchus labrax. Microplastics alone, mercury alone and all the mixtures caused significant reduction of the swimming velocity and resistance time of fish. Moreover, changes in behavioural responses including lethargic and erratic swimming behaviour were observed. These results highlight that fish behavioural responses can be used as sensitive endpoint to establish the effects of contamination by microplastics and also emphasizes the need to assess the combined effects of microplastics and other environmental contaminants, with special attention to the effects on behavioural responses in fish and other aquatic species.

PMID- 29449116 TI - Chronic impacts of oxytetracycline on mesophilic anaerobic digestion of excess sludge: Inhibition of hydrolytic acidification and enrichment of antibiotic resistome. AB - We evaluated the chronic impact of oxytetracycline (OTC) on performance and antibiotic resistance development during the mesophilic anaerobic digestion (AD) of antibiotic-containing biomass. Mesophilic AD was conducted in a completely stirred tank reactor by constantly feeding municipal excess sludge spiked with increasing concentrations of OTC (0-1000 mg L-1) under a solid retention time of 20 days over a period of 265 days. Results showed that methane generation of mesophilic AD was inhibited when the OTC concentration in digested sludge was increased to around 18,000 mg kg-1 (OTC dose, 1000 mg L-1), due to the inhibition of fermenting and acidogenic bacteria. Metagenomic sequencing and high-throughput quantitative PCR analysis demonstrated that tetracycline resistance genes were the most dominant type (38.47-43.76%) in the resistome, with tetG, tetX, tetM, tetR, tetQ, tetO, and tetL as the dominant resistant subtypes throughout the whole experimental period. The relative abundance of these tet genes increased from 2.10 * 10-1 before spiking OTC (OTC concentration in digested sludge, 8.97 mg kg-1) to 2.83 * 10-1 (p < 0.05) after spiking OTC at a dose of 40 mg L-1 (OTC concentration in digested sludge, 528.52 mg kg-1). Furthermore, mobile genetic elements, including integrons, transposons, and plasmids, were also enriched with the increase in OTC dose. Based on partial canonical correspondence analysis, the contributions of horizontal (mobile element alteration) and vertical (bacterial community shift) gene transfer to antibiotic resistome variation were 29.35% and 21.51%, respectively. Thus, considering the inhibition of hydrolytic acidification and enrichment of antibiotic resistome, mesophilic AD is not suggested to directly treat the biomass containing OTC concentration higher than 200 mg L-1. PMID- 29449118 TI - Shot by a Gun ... Missed by a Provider. AB - BACKGROUND: Botulism is a paralytic disease caused by the neurotoxin produced by Clostridium botulinum. The majority of cases are due to ingestion or injection drug use. Wound botulism from traumatic injury is exceedingly rare, with only one to two cases reported each year in the United States. CASE REPORT: A 27-year-old man presented to the Emergency Department with diplopia, dysphagia, and progressive weakness 10 days after sustaining a gunshot wound to his right lower leg. He had been evaluated for the same complaints at a different facility the day prior and was discharged. His wound appeared well-healing, but a high suspicion for wound botulism led to rapid consultation with the state Poison Control Center and the Centers for Disease Control and Prevention. The patient developed worsening respiratory insufficiency and required mechanical ventilation. Expeditious treatment with equine heptavalent botulinum antitoxin resulted in significant recovery of strength in 4 days. Serum toxin bioassay tested positive for botulinum neurotoxin type A. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Wound botulism now accounts for the majority of adult botulism in the United States. It should be considered in any patient with signs of neuromuscular disease and a recent injury, even if the wound appears uninfected. PMID- 29449119 TI - Violence Against Health Care Providers: A Mixed-Methods Study from Karachi, Pakistan. AB - BACKGROUND: Violence against health care providers (HCPs) remains a significant public health problem in developing countries, affecting their performance and motivation. OBJECTIVES: To report the quantity and perceived causes of violence committed upon HCPs and identify strategies intended to prevent and de-escalate it. METHODS: This was a mixed-methods concurrent study design (QUAN-QUAL). A structured questionnaire was filled in on-site by trained data collectors for quantitative study. Sites were tertiary care hospitals, local nongovernmental organizations (NGOs) providing health services, and ambulance services. Qualitative data were collected through in-depth interviews and focus group discussions at these same sites, as well as with other stakeholders including media and law enforcement agencies. RESULTS: One-third of the participants had experienced some form of violence in the last 12 months. Verbal violence was experienced more frequently (30.5%) than physical violence (14.6%). Persons who accompanied patients (58.1%) were found to be the chief perpetrators. Security staff and ambulance staff were significantly more likely to report physical violence (p = 0.001). Private hospitals and local NGOs providing health services were significantly less likely to report physical violence (p = 0.002). HCPs complained about poor facilities, heavy workload, and lack of preparedness to deal with violence. The deficiencies highlighted predominantly included inadequate security and lack of training to respond effectively to violence. Most stakeholders thought that poor quality of services and low capacity of HCPs contributed significantly to violent incidents. CONCLUSION: There is a great need to design interventions that can help in addressing the behavioral, institutional, and sociopolitical factors promoting violence against HCPs. Future projects should focus on designing interventions to prevent and mitigate violence at multiple levels. PMID- 29449120 TI - Bilateral Phlegmasia Cerulea Dolens After Warfarin Reversal for Acute Rectal Bleeding: A Case Report. AB - BACKGROUND: Deep vein thrombosis (DVT) is a common disease that is diagnosed in approximately 1 in 1000 adults annually. Extensive DVT can lead to life- or limb threatening diagnoses such as phlegmasia cerulea dolens (PCD), phlegmasia alba dolens, and venous gangrene. PCD, also known as massive iliofemoral venous thrombosis, is rare, and a severe complication of DVT. CASE REPORT: We report a case of a 94-year-old bedridden woman with past medical history of dementia, hypertension, pulmonary embolism, DVT, and atrial fibrillation. The patient was admitted to the hospital for bright red blood per rectum and an elevated international normalized ratio (INR) of 5.7. On admission, her dose of warfarin was suspended and she was given 4 units of fresh frozen plasma as well as 10 mg of i.v. vitamin K. She was discharged home with an INR normalized to 1.3 and cessation of her rectal bleeding. At discharge, she was not restarted on warfarin, nor was any bridging therapy used. The patient returned to the Emergency Department a week later for worsening pain and bluish discoloration of her bilateral lower extremities. An ultrasound (US) examination showed that she had developed bilateral PCD, after INR reversal. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Emergency physicians commonly care for patients who present with acute DVT or treat patients on anticoagulant therapy who require cessation of medications or administration of prothrombotic agents to reverse bleeding. Cases of extensive clot burden leading to PCD have been reported in the literature, however, reports of bilateral PCD secondary to cessation of warfarin have been scarce. PCD should be considered carefully as one of the complications in warfarin reversal, as it requires immediate attention and surgical intervention to prevent limb loss. PMID- 29449121 TI - Sleep disorders and Parkinson disease; lessons from genetics. AB - Parkinson disease is a common, age-related neurodegenerative disorder, projected to afflict millions of individuals in the near future. Understanding its etiology and identifying clinical, genetic or biological markers for Parkinson disease onset and progression is therefore of major importance. Various sleep-related disorders are the most common group of non-motor symptoms in advanced Parkinson disease, but they can also occur during its prodromal phase. However, with the exception of REM sleep behavior disorder, it is unclear whether they are part of the early pathological process of Parkinson disease, or if they develop as Parkinson disease advances because of treatments and neurodegeneration progression. The advancements in genetic studies in the past two decades have generated a wealth of information, and recent genetic studies offer new insight on the association of sleep-related disorders with Parkinson disease. More specifically, comparing genetic data between Parkinson disease and sleep-related disorders can clarify their association, which may assist in determining whether they can serve as clinical markers for Parkinson disease risk or progression. In this review, we discuss the current knowledge on the genetics of sleep-related disorders in Parkinson disease context, and the potential implications on research, diagnosis, counseling and treatment. PMID- 29449122 TI - Non-pharmacological interventions for improving postpartum maternal sleep: A systematic review and meta-analysis. AB - Evidence suggests that poor postpartum sleep quality is a risk factor for the development of postpartum depression. As such, non-pharmacological interventions have been developed to help improve sleep in the postpartum period. The primary aims of this systematic review and meta-analysis were to determine if non pharmacological interventions improved maternal sleep and to compare the effectiveness of different intervention types. Secondary aims included examining effects on maternal mood and infant sleep. We searched MEDLINE, EMBASE, CINAHL, PsycINFO, and Web of Science from their inceptions to September 2017 and found 15 eligible studies. Non-pharmacological sleep interventions were found to improve subjective reports of maternal sleep (Cohen's d = -0.54, 95%CI = -0.88 to -0.19). Massage (Cohen's d = -1.07 95%CI = -1.34 to -0.79) and exercise (Cohen's d = 0.82 95%CI = -1.28 to -0.37) interventions had the largest impact on maternal sleep quality. Positive effects on nocturnal infant sleep were found for interventions overall (Cohen's d = -0.27 95%CI = -0.52 to -0.02) but not for maternal depression (Cohen's d = -0.08 95%CI = -0.28 to 0.12). Despite evidence suggesting improvements in subjective maternal sleep, more research must be conducted on the durability of effects of non-pharmacological interventions using objective measures of sleep quality. PMID- 29449123 TI - Early Impact of Medicaid Expansion and Quality of Breast Cancer Care in Kentucky. AB - BACKGROUND: In January 2014, Kentucky expanded Medicaid coverage to include all individuals and families with incomes up to 33% above the federal poverty line. This study evaluated the early impact of Medicaid expansion on some aspects of the quality of breast cancer care in Kentucky. STUDY DESIGN: The Kentucky Cancer Registry was queried for all women aged 20 to 64 years diagnosed with breast cancer between 2011 and 2016. Demographic, tumor, and treatment characteristics were assessed for each year during this interval. To evaluate the association between Medicaid expansion and these parameters, these variables, along with quality metrics deriving from said variables, were compared for the years 2011 to 2013 (pre) and the years 2014 to 2016 (post). RESULTS: Of 13,625 women with breast cancer, 11,915 (59.5%) were diagnosed and treated from 2011 to 2013, and 8,127 (40.5%) were diagnosed and treated from 2014 to 2016. After Medicaid expansion, fewer patients were uninsured (3.7% post vs 1.0% pre) and more were covered by Medicaid (15.9% post vs 10.9% pre) (p < 0.001). There was increased diagnosis of early stage (I and II) breast cancer (p = 0.002) and an increasing proportion of women undergoing breast-conservation therapy (p < 0.001). Time from diagnosis to operation increased (p < 0.001), time from operation to chemotherapy remained unchanged (p = 0.26) and time from operation to radiation decreased (p < 0.001). CONCLUSIONS: The expansion of Kentucky Medicaid in 2014 has been associated with earlier diagnosis and somewhat improved quality of breast cancer care, despite a stable disease incidence. Additional improvements in treatment expediency will require improvements in patient outreach and healthcare infrastructure. PMID- 29449124 TI - Investigating PKA-RII specificity using analogs of the PKA:AKAP peptide inhibitor STAD-2. AB - Generation of the second messenger molecule cAMP mediates a variety of cellular responses which are essential for critical cellular processes. In response to elevated cAMP levels, cAMP dependent protein kinase (PKA) phosphorylates serine and threonine residues on a wide variety of target substrates. In order to enhance the precision and directionality of these signaling events, PKA is localized to discrete locations within the cell by A-kinase anchoring proteins (AKAPs). The interaction between PKA and AKAPs is mediated via an amphipathic alpha-helix derived from AKAPs which binds to a stable hydrophobic groove formed in the dimerization/docking (D/D) domain of PKA-R in an isoform-specific fashion. Although numerous AKAP disruptors have previously been identified that can inhibit either RI- or RII-selective AKAPs, no AKAP disruptors have been identified that have isoform specificity for RIalpha versus RIbeta or RIIalpha versus RIIbeta. As a strategy to identify isoform-specific AKAP inhibitors, a library of chemically stapled protein-protein interaction (PPI) disruptors was developed based on the RII-selective AKAP disruptor, STAD-2. An alanine was substituted at each position in the sequence, and from this library it was possible to delineate the importance of longer aliphatic residues in the formation of a region which complements the hydrophobic cleft formed by the D/D domain. Interestingly, lysine residues that were added to both terminal ends of the peptide sequence to facilitate water solubility appear to contribute to isoform specificity for RIIalpha over RIIbeta while having only weak interaction with RI. This work supports current hypotheses on the mechanisms of AKAP binding and highlights the significance of particular residue positions that aid in distinguishing between the RII isoforms and may provide insight into future design of isoform-selective AKAP disruptors. PMID- 29449125 TI - Enhancing the anti-biofilm activity of 5-aryl-2-aminoimidazoles through nature inspired dimerisation. AB - The increased tolerance of biofilms against disinfectants and antibiotics has stimulated research into new methods of biofilm prevention and eradication. In our previous work, we have identified the 5-aryl-2-aminoimidazole core as a scaffold that demonstrates preventive activity against biofilm formation of a broad range of bacterial and fungal species. Inspired by the dimeric nature of natural 2-aminoimidazoles of the oroidin family, we investigated the potential of dimers of our decorated 5-aryl-2-aminoimidazoles as biofilm inhibitors. A synthetic approach towards 2-aminoimidazole dimers linked by an alkyl chain was developed and a total of 48 dimers were synthesized. The linkers were introduced at two different positions, the N1-position or the N2-position, and the linker length and the substitution of the 5-phenyl ring (H, F, Cl, Br) were varied. Although, no clear correlation between linker length and biofilm inhibition was observed, a strong increase in anti-biofilm activity for almost all N1,N1'-linked dimers was obtained, compared to the respective monomers against Salmonella Typhimurium, Escherichia coli and Staphylococcus aureus. The N2,N2'-linked dimers, having a H- or F-substitution, were also found to show a strong increase in anti-biofilm activity compared to the respective monomers against these three bacterial species and against Pseudomonas aeruginosa. In addition, the obtained growth measurements suggest a broad concentration range with specific biofilm inhibition and no effect on the planktonic growth against Salmonella Typhimurium and Pseudomonas aeruginosa. PMID- 29449126 TI - Thrombelastography Suggests Hypercoagulability in Patients with Renal Dysfunction and Intracerebral Hemorrhage. AB - BACKGROUND: The objective of this study was to quantify coagulopathy using thrombelastography (TEG) in patients with renal dysfunction and intracerebral hemorrhage (ICH). METHODS: We reviewed patients admitted with spontaneous ICH between November 2009 and May 2015. TEG was performed at the time of admission. Creatinine clearance (CCr) was calculated using the Cockroft-Gault equation. Patients were divided into 2 groups based on normal (CCr >= 90) or reduced renal function (CCr < 90). Multivariable regression models were conducted to compare the differences of TEG components. RESULTS: A total of 120 patients were included in the analysis. The normal CCr group was younger (56.1 versus 62.3 years, P < .01), was more often male (73.6% versus 53.7%, P = .03), and had higher mean admission hemoglobin (14.2 versus 13.2 mEq/L, P < .01) than the reduced renal function group. The 2 groups were similar with respect to antiplatelet or anticoagulant use, coagulation studies, and baseline ICH volume. Following multivariate analysis, the reduced renal function group was found to have shorter K (1.5 versus 2.2 min, P = 004), increased angle (66 versus 62.2 degrees, P = .04), increased MA (67.3 versus 62.3, P = .02), and increased G (11.3 versus 9.9 dynes/cm2, P = .04) compared with the normal group. Mortality, poor functional outcome (modified Rankin Scale score 4-6), hematoma enlargement, hospital length of stay, and surgical interventions were not different between the 2 groups. CONCLUSIONS: Patients with ICH and reduced CCr display faster clotting rate and increased clot strength, suggesting that patients with renal dysfunction present with a relatively hypercoagulable state based on TEG parameters thought to reflect platelet activity. PMID- 29449127 TI - Evaluating the Effect of Six Proton Pump Inhibitors on the Antiplatelet Effects of Clopidogrel. AB - BACKGROUND AND GOAL: Cytochrome P450 (CYP) enzymes are responsible for the conversion of clopidogrel into its active metabolite and the metabolism of proton pump inhibitors (PPIs), which may also inhibit CYP enzymes. A current Food and Drug Administration advisory suggests avoiding esomeprazole and omeprazole while taking clopidogrel because of concerns that PPIs may compromise clopidogrel's antiplatelet effects. The objective of the present study was to examine the robustness of this interaction using a well-controlled study design in a population of participants free of confounders. MATERIALS AND METHODS: Twenty eight healthy male participants, with a mean age 24.2 +/- 3.2, were randomized to an incomplete crossover design schedule. Participants underwent platelet aggregation testing after clopidogrel alone, while on clopidogrel in combination with 1 of 3 PPIs (40 mg of pantoprazole, 20 mg of omeprazole, 20 mg of rabeprazole, 40 mg of esomeprazole, 30 mg of lansoprazole, or 30 mg of dexlansoprazole), and during 1 week of clopidogrel-only washout periods. FINDINGS: The median platelet aggregation to adenosine diphosphate during a drug free baseline was 10Omega (2.5 interquartile range) of impedance and decreased to 0Omega on clopidogrel alone. Aggregation did not significantly change with concomitant use of PPIs and clopidogrel. CONCLUSION: These data do not demonstrate a significant interaction between common individual PPIs and clopidogrel in healthy volunteers who respond to clopidogrel alone. This adds data to a growing body of evidence indicating that the addition of a PPI may have a weak effect on clopidogrel's antiplatelet properties, and may only be relevant in specific clinical circumstances. PMID- 29449128 TI - Meta-Analysis on the Association between Brain-Derived Neurotrophic Factor Polymorphism rs6265 and Ischemic Stroke, Poststroke Depression. AB - BACKGROUND: Ischemic stroke is a multifactorial neurologic injury that causes mortality and disability worldwide. Poststroke depression is the most important neuropsychiatric consequence of stroke. Brain-derived neurotrophic factor is a neurotrophin family member that plays key role in regulating neuron survival and differentiation. Studies found a polymorphism in brain-derived neurotrophic factor gene (rs6265) may associate with the ischemic stroke and poststroke depression risk. However, the results are inconclusive and inconsistent. METHODS: In the present meta-analysis, the database PubMed, Embase, Cochrane Central Register of Controlled Trials, CNKI, and Chinese Biomedical Literature Database were searched until July 9, 2017. RESULTS: Seven studies with 1287 cases and 1032 controls were included for the meta-analysis of ischemic stroke, and five studies with 272 cases and 503 controls were included for poststroke depression. The results indicated that the GG genotype of brain-derived neurotrophic factor is related to a significantly lower risk of ischemic stroke in the homozygous and dominant models (odds ratio = .57 and .80, respectively). No significant relation was found between rs6265 and poststroke depression. CONCLUSIONS: Thus, brain derived neurotrophic factor rs6265 might be recommended as a predictor of susceptibility of ischemic stroke. However, the results of this meta-analysis should be interpreted with caution because of the heterogeneity between studies and low sample size. Further studies are needed to evaluate the associations between rs6265 and poststroke depression, especially in Caucasians, with large sample size.

AB - Pseudomonas aeruginosa exhibits the biofilm mode of growth and causes chronic as well as acute infections in humans. Several reports have shown that the treatments with sub-minimum inhibitory concentrations (sub-MICs) of antimicrobial agents influence biofilm formation by P. aeruginosa. The antibiotic ceftazidime (CAZ) is used to treat P. aeruginosa infections, but few studies have examined the effects of beta-lactams on biofilm formation by P. aeruginosa. In this study, we investigated the role of sub-MICs of CAZ in the formation of P. aeruginosa biofilms. 1/4 * MIC CAZ reduced the biofilm volume of P. aeruginosa PAO1, as quantified by crystal violet staining. The formation of P. aeruginosa PAO1 biofilms treated with 1/4 * MIC CAZ were observed by confocal laser scanning microscopy. They were more heterogeneous than the PAO1 biofilms without CAZ treatment. Furthermore, sub-MICs of CAZ inhibited the twitching motility, which played an important role in mature biofilm formation. 1/4 * MIC CAZ also reduced the gene expressions of lecA, lecB, pel and psl, which mediate the adhesion and polysaccharide matrix synthesis of P. aeruginosa. These effects suggest that sub MICs of CAZ may affect a number of stages of biofilm formation. Investigating the effects of sub-MIC antibiotics on targeted bacterial biofilm may lead to the development of future antibiotic treatment modalities. PMID- 29449130 TI - The NASA Task Load Index as a measure of overall workload among neonatal, paediatric and adult intensive care nurses. AB - INTRODUCTION: The NASA Task Load Index (NASA-TLX) is a subjective workload assessment scale developed for use in aviation and increasingly applied to healthcare. The scale purports to measure overall workload as a single variable calculated by summing responses to six items. Since no data address the validity of this scoring approach in health care, we evaluated the single factor structure of the NASA-TLX as a measure of overall workload among intenisive care nurses. METHODS: Confirmatory factor analysis of data from two studies of nurse workload in neonatal, paediatric, and adult intensive care units. Study 1 data were obtained from 136 nurses in one neonatal intensive care unit. Study 2 data were collected from 300 nurses in 17 adult, paediatric and neonatal units. Nurses rated their workload using the NASA-TLX's paper version. RESULTS: A single factor model testing whether all six items measured a single overall workload variable fit least well (RMSEA = 0.14; CFI = 0.91; TLI = 0.85). A second model that specified two items as outcomes of overall workload had acceptable fit (RMSEA = 0.08; CFI = 0.97; TLI = 0.95) while a third model of four items fit best (RMSEA = 0.06; CFI > 0.99; TLI = 0.99). CONCLUSION: A summed score from four of six NASA TLX items appears to most reliably measure a single overall workload variable among intensive care nurses. PMID- 29449131 TI - The treatment of anti-phospholipid syndrome: A comprehensive clinical approach. AB - Anti-phospholipid syndrome (APS) is an acquired pro-thrombotic autoimmune disease that predisposes to thrombotic events and/or obstetric complications, in the persistent presence of anti-phospholipid antibodies (aPL). Life long moderate intensity anticoagulation is the option of choice for aPL-positive patients with a previous thrombosis; critical issues concern the management of those with a history of arterial event due to the high rate of recurrence. Alternatives comprise anti-platelet agents and high-intensity anticoagulation. Low dose aspirin (LDASA) and low molecular weight heparin provide the mainstay of the treatment of obstetric APS, allowing a birth rate in 70% of cases. The management of refractory APS, thrombotic as well as obstetric, is highly debated, but an increasing burden of evidence points towards the beneficial effects of multiple treatments. Similarly, a management envisaging multiple drugs (anticoagulation, steroids, plasma exchange and/or intravenous immunoglobulins) is the most effective approach in catastrophic APS. Asymptomatic aPL carriers are at higher risk of thrombotic and obstetric complications compared to the general population, thus potentially benefitting of a pharmacological intervention. LDASA and hydroxychloroquine can be considered as options, in particular in case of high risk aPL profile, concomitant cardiovascular risk factors or associated autoimmune disease. APS is apparently a simple condition, but its multifaceted nature requires a complex and tailored treatment.

AB - INTRODUCTION: Electronic cigarettes (e-cigarettes) are often promoted to assist with cigarette smoking cessation. In 2016-2017, the relationship between e cigarette use and having stopped smoking among ever (current and former) smokers was assessed in the European Union and Great Britain by itself. METHODS: Cross sectional logistic regression of the association between being a former smoker and e-cigarette use was applied to the 2014 Eurobarometer survey of 28 European Union countries controlling for demographics. RESULTS: Among all ever smokers, any regular ever use of nicotine e-cigarettes was associated with lower odds of being a former smoker (unadjusted OR=0.34, 95% CI=0.26, 0.43, AOR=0.43, 95% CI=0.32, 0.58) compared with smokers who had never used e-cigarettes. In unadjusted models, daily use (OR=0.42, 95% CI=0.31, 0.56); occasional use (OR=0.25, 95% CI=0.18, 0.35); and experimentation (OR=0.24, 95% CI=0.19, 0.30) of nicotine e-cigarettes were associated with lower odds of being a former smoker compared with having never used nicotine-containing e-cigarettes. Comparable results were found in adjusted models. Results were similar in Great Britain alone. Among current smokers, daily cigarette consumption was 15.6 cigarettes/day (95% CI=14.5, 16.7) among those who also used e-cigarettes versus 14.4 cigarettes/day (95% CI=13.4, 15.4) for those who did not use them (p<0.05). CONCLUSIONS: These results suggest that e-cigarettes are associated with inhibiting rather than assisting in smoking cessation. On the population level, the net effect of the entry of e-cigarettes into the European Union (and Great Britain) is associated with depressed smoking cessation of conventional cigarettes. PMID- 29449133 TI - Evaluation of Medicare's Intensive Behavioral Therapy for Obesity: the BieneStar Experience. AB - INTRODUCTION: In 2011, the Centers for Medicare and Medicaid Services began to reimburse primary care providers for intensive behavior therapy for obesity. This study evaluated a Centers for Medicare and Medicaid Services intensive behavior therapy for obesity program as implemented in primary care clinics. METHODS: Data for this retrospective cohort study were obtained between May 2012 and February 2015 and statistical analysis was performed in 2017. The sample included 643 participants who attended at least one BieneStar intensive behavior therapy for obesity program session. The primary outcome was weight, and covariates were number of sessions, age, race/ethnicity, diagnosis of hypertension and diabetes, and type of health insurance. RESULTS: Of 643 participants that initiated the BieneStar program, 641 had complete data. The median reduction in weight of participants was as follows: those who attended fewer than four sessions, 0 kg (95% CI=0, 0.11 kg); between four and eight sessions, 1.1 kg (95% CI=0.86, 1.59 kg); and more than eight sessions 3.7 kg (95% CI=3.36, 4.55 kg). Medians of weight were significantly different between each classification of session numbers (p<0.01). Participants lost on average 0.102 kg of weight per session attended. CONCLUSIONS: The BieneStar program showed that the weight of participants decreased as they attended more sessions. Further studies are needed to determine if these results can be reproduced in other office-based primary care clinics and the program's impact on chronic disease.

AB - INTRODUCTION: Youth sexual violence victimization is an urgent public health concern that can lead to a variety of health problems and increased risk for victimization during adulthood. Examining the characteristics of early victimization and their association with subsequent victimization during adulthood may help strengthen primary prevention efforts. METHODS: Data are from the 2012 National Intimate Partner and Sexual Violence Survey. Prevalence estimates were computed in 2017 for rape and made to sexually penetrate, their subtypes, as well as proportions among victims by type of perpetrator. Chi-square tests of association were conducted between youth sexual violence victimization and the same experiences in adulthood. RESULTS: Approximately 10 million U.S. females (8.4%) experienced completed or attempted rape and 1.9 million U.S. males (1.6%) were made to penetrate someone during youth. Most victims knew their perpetrators. Being raped or made to penetrate during youth was associated with increased likelihood of such victimization in adulthood. CONCLUSIONS: Females and males experience youth sexual violence victimization at alarming rates. Primary prevention efforts with youth are critical to prevent early victimization, subsequent victimization in adulthood, and the mental and physical health consequences associated with sexual violence victimization. PMID- 29449135 TI - Effects of Before-School Physical Activity on Obesity Prevention and Wellness. AB - INTRODUCTION: The effects of Build Our Kids Success-a 12-week, 1-hour before school physical activity program-on BMI and social-emotional wellness among kindergarten to eighth grade students was examined. STUDY DESIGN: This was a nonrandomized trial. SETTING/PARTICIPANTS: Participants were from 24 schools in Massachusetts; there were 707 children from kindergarten to eighth grade. INTERVENTION: Children registered for Build Our Kids Success in 2015-2016 participated in a 2 days/week or 3 days/week program. Nonparticipating children served as controls. MAIN OUTCOME MEASURES: At baseline and 12 weeks, study staff measured children's heights/weights; children aged >=8 years completed surveys. Main outcomes were 12-week change in BMI z-score, odds of a lower BMI category at follow-up, and child report of social-emotional wellness. Analyses were completed in March-June 2017. RESULTS: Follow-up BMI was obtained from 67% of children and self-reported surveys from 72% of age-eligible children. Children in the 3 days/week group had improvements in BMI z-score (-0.22, 95% CI= -0.31, -0.14) and this mean change was significantly different than the comparison group (-0.17 difference, 95% CI= -0.27, -0.07). Children in the 3 days/week group also had higher odds of being in a lower BMI category at follow-up (OR=1.35, 95% CI=1.12, 1.62); significantly different than the comparison group (p<0.01). Children in the 2 days/week program had no significant changes in BMI outcomes. Children in the 3 days/week group demonstrated improvement in their student engagement scores (0.79 units, p=0.05) and had nonsignificant improvements in reported peer relationships, affect, and life satisfaction versus comparison. The 2 days/week group had significant improvements in positive affect and vitality/energy versus comparison. CONCLUSIONS: A 3 days/week before-school physical activity program resulted in improved BMI and prevented increases in child obesity. Both Build Our Kids Success groups had improved social-emotional wellness versus controls. TRIAL REGISTRATION: This study is registered at www.clinicaltrials.gov NCT03190135. PMID- 29449136 TI - Sexual Orientation Discordance and Nonfatal Suicidal Behaviors in U.S. High School Students. AB - INTRODUCTION: Studies among adults have documented association between sexual orientation discordance and some suicide risk factors. However, studies examining sexual orientation discordance and nonfatal suicidal behaviors in youth are rare. This study examines the association between sexual orientation discordance and suicidal ideation/suicide attempts among a nationally representative sample of U.S. high school students. METHODS: Using sexual identity and sex of sexual contact measures from the 2015 national Youth Risk Behavior Survey (n=6,790), a sexual orientation discordance variable was constructed describing concordance and discordance (agreement and disagreement, respectively, between sexual identity and sex of sexual contacts). Three suicide-related questions (seriously considered attempting suicide, making a plan about how they would attempt suicide, and attempting suicide) were combined to create a two-level nonfatal suicide risk variable. Analyses were restricted to students who identified as heterosexual or gay/lesbian, who had sexual contact, and who had no missing data for sex or suicide variables. The association between sexual orientation discordance and nonfatal suicide risk was assessed using logistic regression. Analyses were performed in 2017. RESULTS: Approximately 4.0% of students experienced sexual orientation discordance. High suicide risk was significantly more common among discordant students compared with concordant students (46.3% vs 22.4%, p<0.0001). In adjusted models, discordant students were 70% more likely to have had suicidal ideation/suicide attempts compared with concordant students (adjusted prevalence ratio=1.7, 95% CI=1.4, 2.0). CONCLUSIONS: Sexual orientation discordance was associated with increased likelihood of nonfatal suicidal behaviors. Discordant adolescents may experience unique stressors that should be considered when developing and implementing suicide prevention programs. PMID- 29449138 TI - Driving with drug-resistant and controlled seizures from a patient's perspective: Assessment of attitudes and practices. AB - BACKGROUND: Driving restrictions in epilepsy are intended to safeguard public and personal safety; however, these limitations inhibit socialization, restrict employment, and reduce self-esteem in patients with seizures. A large proportion of patients with seizures continue to drive, and factors leading to noncompliance with driving regulations are poorly understood. Thus, the patients' perspective on driving safety is not incorporated into the existing counseling tools on driving safety in epilepsy. The present study assessed social, economic, and psychological perceptions related to driving restrictions in patients with refractory and pharmacotherapy-controlled seizures at the single epilepsy center and identified impediments for safe driving. METHODS: Data were obtained from an anonymous survey completed by 25 adult patients in the presurgical group (PG) with refractory epilepsy and 46 patients in the ambulatory group (AG) with confirmed epilepsy which did not meet criteria for refractoriness. The questionnaire (administered via Research Electronic Data Capture (REDCap)) addressed seizure and driving history, knowledge of driving restrictions, and social consequences of losing driving privileges. RESULTS: Eighty-seven percent of all responders experienced seizures with alteration of awareness; however, 34% of patients continued to drive during the time when they were legally restricted, and 6% had accidents related to seizures. All responders reported their seizure status accurately to the treating physician, and 93% understood state-based driving restrictions. The median time from the last seizure was shorter, and the duration of last driving restriction was longer in the PG compared with the AG (1 vs. 20weeks, and 12 vs. 24weeks, respectively). Despite that, the proportions of patients driving at the time of survey were not significantly different between the two groups. Nearly 80% of all patients stated that driving restrictions reduced their quality of life, and 70% believed that these restrictions carry a social stigma. Employment was chosen to be the most affected by driving restrictions from a list of four social domains by the majority of patients in both groups. Notably, the employment rate was 26% higher in the AG compared with the PG. The lack of public transportation was regarded as a hurdle by more than 60% of patients in each group with greater than two-thirds of patients relying on other drivers for transportation. CONCLUSIONS: These findings suggest that patients with refractory and pharmacotherapy-controlled seizures are similarly likely to drive a vehicle, disregarding a practitioner's advice and state restrictions. The lack of public transportation is a shared constraint and likely leads to reduced compliance with driving regulations. Driving restrictions carry social stigma and limit the employment of patients with epilepsy, regardless of the refractory seizure status. PMID- 29449137 TI - Sex-specific differences in insulin resistance in type 1 diabetes: The CACTI cohort. AB - OBJECTIVE: To test the hypothesis that multitissue deficits in insulin sensitivity are greater among women than men with type 1 diabetes compared to respective controls. RESEARCH DESIGN AND METHODS: Three-stage hyperinsulinemic euglycemic clamps (4, 8, 40 mU/m2/min) were performed on 41 people with type 1 diabetes and 47 adults without diabetes (mean +/- SD age 46 +/- 8). Infusions of [1-13C]palmitate, [1,1,2,3,3-2H2]glycerol, and [6,6-2H2]glucose isotope tracers were used to determine free fatty acid (FFA), glycerol, and glucose kinetics in 52 of these participants (25 M and 27 W). RESULTS: There was no difference in age or BMI by type 1 diabetes status in either sex. Free fatty acid rate of appearance (FFA Ra) was higher in both sexes with type 1 diabetes compared to those without diabetes during stages 1 and 2. The same was seen with glycerol for stages 1 and 2. During stage 3 glucose rate of disappearance (Rd) was lower in those with type 1 diabetes among both sexes. All had sex by type 1 diabetes interactions with greater deficits in insulin sensitivity in women. While there was no sex by diabetes interaction in regards to glucose rate of appearance (Ra), those with type 1 diabetes had a higher glucose Ra than those without diabetes. CONCLUSIONS: We found that type 1 diabetes affected adipose and skeletal muscle insulin sensitivity to a greater extent in women than in men, perhaps contributing to the greater relative increase in cardiovascular risk in women with type 1 diabetes. PMID- 29449139 TI - Problems with access to dental treatment for children with epilepsy. AB - INTRODUCTION: Epilepsy is a common medical disorder and due to a variety of barriers, people with epilepsy may not have access to needed healthcare services, particularly based on their place of residence. OBJECTIVES: The aim of the study was to assess access to dental treatment in children and adolescents with epilepsy in Lublin Voivodeship. MATERIAL AND METHODS: Clinical and questionnaire examinations were performed in 107 children and young people, of both sexes, in the ages between 6 and 18years old from the Lublin macroregion. RESULTS: The majority (77.57%) of respondents regularly visited a general practitioner. Most of the children did not undergo regular dental checkups. Children from the large cities significantly more often went to a dentist compared with examinees from a small town and from rural areas. According to the respondents 46.73% have encountered barriers to dental care of their child. CONCLUSIONS: PMID- 29449140 TI - Effectiveness of a multicomponent self-management intervention for adults with epilepsy (ZMILE study): A randomized controlled trial. AB - BACKGROUND: The objective of the ZMILE study was to compare the effectiveness of a multicomponent self-management intervention (MCI) with care as usual (CAU) in adult patients with epilepsy (PWE) over a six-month period. METHODS: Participants (PWE & relative) were randomized into intervention or CAU groups. Self-report questionnaires were used to measure disease-specific self-efficacy as the primary outcome measure and general self-efficacy, adherence, seizure severity, emotional functioning, quality of life, proactive coping, and side-effects of antiepileptic drugs (AED) as secondary outcome measures. Instruments used at baseline and during a six-month follow-up period were the following: disease-specific self efficacy (Epilepsy Self-Efficacy Scale [ESES], General Self-Efficacy Scale [GSES]); adherence (Medication Adherence Scale [MARS] and Medication Event Monitoring System [MEMS]); seizure severity (National Hospital Seizure Severity Scale [NHS3]); emotional well-being (Hospital Anxiety and Depression Scale [HADS]); quality of life (Quality of Life in Epilepsy [QOLIE-31P]); proactive coping (Utrecht Proactive Coping Competence [UPCC]); and side-effects of antiepileptic drugs [SIDAED]. Multilevel analyses were performed, and baseline differences were corrected by inclusion of covariates in the analyses. RESULTS: In total, 102 PWE were included in the study, 52 of whom were in the intervention group. On the SIDAED and on three of the quality of life subscales QOLIE-31P, a significant difference was found (p<0.05) in the intervention group. Self efficacy, however, showed no significant differences between the MCI and the CAU groups. None of the other outcome measures showed any significant difference between the two groups. SIGNIFICANCE: Although we found no statistically significant difference in the primary outcome measure, disease-specific self efficacy, this MCI could prove promising, since we found improvement in some domains of quality of life in epilepsy scale and a decrease in AED side-effects in the MCI group compared with the CAU group. PMID- 29449141 TI - Neurometabolites Alteration in the Acute Phase of Mild Traumatic Brain Injury (mTBI): An In Vivo Proton Magnetic Resonance Spectroscopy (1H-MRS) Study. AB - RATIONALE AND OBJECTIVES: Magnetic resonance spectroscopy is a noninvasive imaging technique that allows for reliable assessment of microscopic changes in brain cytoarchitecture, neuronal injuries, and neurochemical changes resultant from traumatic insults. We aimed to evaluate the acute alteration of neurometabolites in complicated and uncomplicated mild traumatic brain injury (mTBI) patients in comparison to control subjects using proton magnetic resonance spectroscopy (1H magnetic resonance spectroscopy). MATERIAL AND METHODS: Forty eight subjects (23 complicated mTBI [cmTBI] patients, 12 uncomplicated mTBI [umTBI] patients, and 13 controls) underwent magnetic resonance imaging scan with additional single voxel spectroscopy sequence. Magnetic resonance imaging scans for patients were done at an average of 10 hours (standard deviation 4.26) post injury. The single voxel spectroscopy adjacent to side of injury and noninjury regions were analysed to obtain absolute concentrations and ratio relative to creatine of the neurometabolites. One-way analysis of variance was performed to compare neurometabolite concentrations of the three groups, and a correlation study was done between the neurometabolite concentration and Glasgow Coma Scale. RESULTS: Significant difference was found in ratio of N-acetylaspartate to creatine (NAA/Cr + PCr) (chi2(2) = 0.22, P < .05) between the groups. The sum of NAA and N-acetylaspartylglutamate (NAAG) also shows significant differences in both the absolute concentration (NAA + NAAG) and ratio to creatine (NAA + NAAG/Cr + PCr) between groups (chi2(2) = 4.03, P < .05and (chi2(2) = 0.79, P < .05)). NAA values were lower in cmTBI and umTBI compared to control group. A moderate weak positive correlation were found between Glasgow Coma Scale with NAA/Cr + PCr (rho = 0.36, P < .05 and NAA + NAAG/Cr + PCr (rho = 0.45, P < .05)), whereas a moderate correlation was seen with NAA + NAAG (rho = 0.38, P < .05). CONCLUSION: Neurometabolite alterations were already apparent at onset of both complicated and uncomplicated traumatic brain injury. The ratio of NAA and NAAG has potential to serve as a biomarker reflecting injury severity in a quantifiable manner as it discriminates between the complicated and uncomplicated cases of mTBI.

PMID- 29449143 TI - Gender Trends in Academic Radiology Publication in the United States Revisited. AB - RATIONALE AND OBJECTIVES: Although substantial increases in publications by female academic radiologists have appeared over the last several decades, it is possible that the rate of increase is decreasing. We examined temporal trends in gender composition for full-time radiology faculty, radiology residents, and medical students over a 46-year period. METHODS: We examined authorship gender trends to determine if the increases in female authorship seen since 1970 have been sustained in recent years and whether female radiologists continue to publish in proportion to their numbers in academic departments. Original articles for selected years in Radiology and in the American Journal of Roentgenology between 1970 and 2016 were examined to determine the gender of first, corresponding, and last authors. Generalized linear models evaluated (1) changes in proportions of female authorship over time and (2) associations between proportions of female authorship and female radiology faculty representation. RESULTS: While linear increases in first, corresponding, and senior authorships were observed for female radiologists from 1970 to 2000, the rate of increase in female first and corresponding authorships then changed, with the slope of the first author relationship decreasing from 0.81 to 0.34, corresponding to 47% fewer female first authors added per year. In contrast, the proportion of female last authorship continued to increase at the same rate. The proportion of female first authorship was linearly related to the proportion of female radiology faculty from 1970 to 2016. CONCLUSIONS: Annual increases in first author academic productivity of female radiologists have lessened in the past 16 years, possibly related to reductions in the growth of female radiology faculty and trainees. As mixed, compared to homogeneous gender, authorship teams are associated with more citations, efforts to encourage more women to pursue careers in academic radiology could benefit the radiology research community. PMID- 29449144 TI - A Dynamic Graph Cuts Method with Integrated Multiple Feature Maps for Segmenting Kidneys in 2D Ultrasound Images. AB - RATIONALE AND OBJECTIVES: Automatic segmentation of kidneys in ultrasound (US) images remains a challenging task because of high speckle noise, low contrast, and large appearance variations of kidneys in US images. Because texture features may improve the US image segmentation performance, we propose a novel graph cuts method to segment kidney in US images by integrating image intensity information and texture feature maps. MATERIALS AND METHODS: We develop a new graph cuts based method to segment kidney US images by integrating original image intensity information and texture feature maps extracted using Gabor filters. To handle large appearance variation within kidney images and improve computational efficiency, we build a graph of image pixels close to kidney boundary instead of building a graph of the whole image. To make the kidney segmentation robust to weak boundaries, we adopt localized regional information to measure similarity between image pixels for computing edge weights to build the graph of image pixels. The localized graph is dynamically updated and the graph cuts-based segmentation iteratively progresses until convergence. Our method has been evaluated based on kidney US images of 85 subjects. The imaging data of 20 randomly selected subjects were used as training data to tune parameters of the image segmentation method, and the remaining data were used as testing data for validation. RESULTS: Experiment results demonstrated that the proposed method obtained promising segmentation results for bilateral kidneys (average Dice index = 0.9446, average mean distance = 2.2551, average specificity = 0.9971, average accuracy = 0.9919), better than other methods under comparison (P < .05, paired Wilcoxon rank sum tests). CONCLUSIONS: The proposed method achieved promising performance for segmenting kidneys in two-dimensional US images, better than segmentation methods built on any single channel of image information. This method will facilitate extraction of kidney characteristics that may predict important clinical outcomes such as progression of chronic kidney disease. PMID- 29449145 TI - Antithrombotic Therapy Following Venous Stenting: International Delphi Consensus. AB - OBJECTIVE/BACKGROUND: Deep venous stenting is increasingly used in the treatment of deep venous obstruction; however, there is currently no consensus regarding post-procedural antithrombotic therapy. The aim of the present study was to determine the most commonly used antithrombotic regimens and facilitate global consensus. METHODS: An electronic survey containing three clinical scenarios on venous stenting for non-thrombotic iliac vein lesions, acute deep vein thrombosis (DVT), and post-thrombotic syndrome was distributed to five societies whose members included vascular surgeons, interventional radiologists, and haematologists. The results of the initial survey (phase 1) were used to produce seven consensus statements, which were distributed to the respondents for evaluation in the second round (phase 2), along with the results of phase 1. Consensus was defined a priori as endorsement or rejection of a statement by >= 67% of respondents. RESULTS: Phase 1 was completed by 106 experts, who practiced in 78 venous stenting centres in 28 countries. Sixty-one respondents (58% response rate) completed phase 2. Five of seven statements met the consensus criteria. Anticoagulation was the preferred treatment during the first 6-12 months following venous stenting for a compressive iliac vein lesion. Low molecular weight heparin was the antithrombotic agent of choice during the first 2-6 weeks. Lifelong anticoagulation was recommended after multiple DVTs. Discontinuation of anticoagulation after 6-12 months was advised following venous stenting for a single acute DVT. No agreement was reached regarding the role of long-term antiplatelet therapy. CONCLUSIONS: Consensus existed amongst respondents regarding anticoagulant therapy following venous stenting. At present, there is no consensus regarding the role of antiplatelet agents in this context. PMID- 29449146 TI - Efficacy and safety of combination therapy with SGLT2 and DPP4 inhibitors in the treatment of type 2 diabetes: A systematic review and meta-analysis. AB - BACKGROUND: This review evaluated the efficacy and safety of a combination therapy comprising a sodium-glucose cotransporter type 2 inhibitor (SGLT2i) and dipeptidyl peptidase-4 inhibitor (DPP4i) in type 2 diabetes. METHODS: A literature search through to May 2017 was carried out of PubMed, Embase and the Cochrane Central Register of Controlled Trials. Studies were eligible if they were randomized controlled trials (RCTs) comparing SGLT2i plus DPP4i (SGLT2i/DPP4i) against DPP4i+/-placebo or SGLT2i+/-placebo and published in English. The primary outcome was change in HbA1c from baseline. RESULTS: Eight RCTs comparing SGLT2i/DPP4i and DPP4i, and five RCTs comparing SGLT2i/DPP4i and SGLT2i, with three RCTs involving both comparisons, were included in the present review. SGLT2i/DPP4i resulted in a greater mean HbA1c reduction [weighted mean difference (WMD]): -0.62%] than did DPP4i alone, which was a much less marked reduction (WMD: -0.35%) than with SGLT2i alone. Also, significant differences in body weight loss from baseline were observed only with SGLT2i/DPP4i vs. DPP4i, but not vs. SGLT2i. The risk of hypoglycaemic events was low and similar between treatment groups. When subjects were stratified based on baseline HbA1c, any reduction by SGLT2i/DPP4i in relation to DPP4i was proportional to baseline HbA1c levels. However, compared with SGLT2i, HbA1c reductions with SGLT2i/DPP4i were modest regardless of baseline HbA1c. CONCLUSION: Combination therapy with SGLT2i and DPP4i is both efficacious and safe. In particular, a marked additional glucose-lowering effect is evident when SGLT2i is combined with or added to DPP4i, and not vice versa. However, baseline HbA1c determined the additional glucose-lowering effects of SGLT2i in combined treatment with DPP4i.

AB - AIM: The current trend on diabetes management advocates replacing the paradigm from a uniform to an individualized patient-centered haemoglobin A1c (HbA1c) target, but there is no consensus on the optimal HbA1c level. The study aimed at examining the association between HbA1c and the risk of cardiovascular diseases (CVD) for diabetic patients with different characteristics, in order to identify patient-centered treatment targets. METHODS: A retrospective cohort study was conducted on 115,782 Chinese adult primary care patients with type 2 diabetes mellitus (DM) but no known CVD history, who were prescribed antidiabetic medications in 2010-2011. The cumulative mean HbA1c over a median follow-up period of 5.8 years was used to evaluate the relationship between HbA1c and CVD incidence using Cox analysis. Subgroup analyses were conducted by stratifying different baseline characteristics including gender, age, smoking status, diabetes duration, body mass index, Charlson's comorbidity index and DM treatment modalities. RESULTS: For patients with a DM duration of<2years, an exponential relationship between HbA1c and risk of CVD was identified, suggesting that there was no threshold HbA1c level for CVD risk. For other diabetic patients, an HbA1c level of 6.8-7.2% was associated with a minimum risk for CVD and a J-shaped curvilinear association between HbA1c. The risk of CVD increased in patients with HbA1c<6.5% or >=7.5%. CONCLUSION: Among Chinese primary care patients at the early (<2years) disease stage, lower HbA1c targets (<6.5%) may be warranted to prevent CVD events whilst for all others, excessively lower HbA1c levels may not necessarily better and can potentially be harmful. PMID- 29449149 TI - Manufacturing Exosomes: A Promising Therapeutic Platform. AB - Extracellular vesicles, in particular the subclass exosomes, are rapidly emerging as a novel therapeutic platform. However, currently very few clinical validation studies and no clearly defined manufacturing process exist. As exosomes progress towards the clinic for treatment of a vast array of diseases, it is important to define the engineering basis for their manufacture early in the development cycle to ensure they can be produced cost-effectively at the appropriate scale. We hypothesize that transitioning to defined manufacturing platforms will increase consistency of the exosome product and improve their clinical advancement as a new therapeutic tool. We present manufacturing technologies and strategies that are being implemented and consider their application for the transition from bench-scale to clinical production of exosomes.

AB - BACKGROUND/OBJECTIVES: Time-intensity curve (TIC) under contrast-enhanced EUS (CE EUS) allows continuous and quantitative evaluation of targeted area in the pancreas. However, TIC is not always available and the procedure is complicated. We aimed to propose a simplified method by evaluating multiple phases of CE-EUS in the diagnosis of pancreatic solid lesions. METHODS: We retrospectively reviewed 210 patients with pancreatic solid lesions including 142 with pancreatic ductal cancer (PDAC), 31 with pancreatic neuroendocrine neoplasm, 13 with solid pseudopapillary neoplasm and 24 with mass-forming pancreatitis who underwent CE EUS and achieved final diagnoses. The CE-EUS images were continuously recorded for 60 s, and each image at 20, 40 and 60 s was used for the evaluation. The images were classified into three patterns as hypoechoic, hyperechoic and isoechoic vascular patterns compared with the surrounding pancreas, and the relevance between the multiphase evaluation of CE-EUS and each disease group was investigated. RESULTS: In PDAC group, majority of the lesions showed hypovascular pattern at 20 or 40 s after injection of contrast medium following early enhancement. The sensitivity, specificity and accuracy of PDAC pattern in the differentiation of PDAC from other lesions was 83.1%, 86.8% and 84.3%, respectively. On histopathological analysis, significant differences were seen in histologic types, infiltration (INF), and neural invasion (ne) between those who showed PDAC pattern and those who didn't. CONCLUSIONS: Multiphase evaluation of CE-EUS is convenient and useful method for the differentiation of pancreatic solid lesions which can be alternatively used for TIC. PMID- 29449152 TI - Development of the Health and Weight Attitudes Scale. AB - OBJECTIVE: To develop and validate an instrument to assess attitudes toward Health at Every Size (HAES) principles. METHODS: Survey items were generated based on 5 HAES principles. A panel of reviewers was recruited to establish content validity. A convenience sample of college students in health education was recruited for pilot survey administration. Internal reliability was assessed using Cronbach alpha and test-retest reliability was assessed with Pearson correlation. RESULTS: Three panelists reviewed the instrument and provided feedback for revision. Cronbach alpha for the final instrument was .75 (n = 43) at pretest and .78 (n = 53) at posttest, and Pearson correlation was 0.85 (n = 39), indicating internal consistency and test-retest reliability. CONCLUSIONS AND IMPLICATIONS: The instrument was determined to be both a valid and reliable instrument to measure HAES attitudes among college students in health education. Nutrition educators may find this instrument useful in other settings to assess HAES attitudes or as an alternative to other instruments measuring anti-fat attitudes. PMID- 29449153 TI - Exploring Grandparents' Roles in Young Children's Lifestyle Behaviors and the Prevention of Childhood Obesity: An Australian Perspective. AB - Childhood obesity remains a significant public health issue. Because lifestyle behaviors and weight are established early and track through life stages, prevention strategies must commence in the first years of life. Traditionally, such strategies target parents or formal child care providers. Yet grandparents are increasingly providing care to grandchildren and therefore have an important role in their eating and activity behaviors, which creates a major research gap. This commentary piece, focusing on the Australian context, argues that it is imperative and timely for obesity prevention research to include investigations regarding the role of grandparents in the prevention of obesity-related behaviors in young children. PMID- 29449148 TI - Therapeutic Targeting of Long Non-Coding RNAs in Cancer. AB - Long non-coding RNAs (lncRNAs) represent a significant population of the human transcriptome. Many lncRNAs exhibit cell- and/or tissue/tumor-specific expression, making them excellent candidates for therapeutic applications. In this review we discuss examples of lncRNAs that demonstrate the diversity of their function in various cancer types. We also discuss recent advances in nucleic acid drug development with a focus on oligonucleotide-based therapies as a novel approach to inhibit tumor progression. The increased success rates of nucleic acid therapeutics provide an outstanding opportunity to explore lncRNAs as viable therapeutic targets to combat various aspects of cancer progression.

AB - BACKGROUND: Understanding the prevalence of, and factors associated with, caesarean birth among immigrant populations is essential for appropriate antenatal and postnatal resource allocation. AIMS: To compare rates of caesarean birth between one of the largest immigrant populations of women giving birth in Australia (Vietnamese-born women) with those of Australian-born women and investigate the odds of unplanned caesarean in these women, controlling for maternal characteristics, pregnancy complications and labour management factors. METHODS: Cross-sectional analysis of data on singleton births in Victoria, Australia; using data from the routinely collected Victorian Perinatal Data Collection. Descriptive analyses comparing maternal and obstetric factors for Vietnamese-born women with Australian-born women were undertaken. Using the more recent nine years of routinely collected data, multivariable logistic regression explored the association between unplanned caesarean birth and maternal country of birth, adjusted for maternal and obstetric factors, admission status and time (n=468,131). This association was also explored for 'standard primiparae' (n=69,039). FINDINGS: Planned and unplanned caesarean births increased dramatically in both Australian-born and Vietnamese-born women between 1984 and 2007. After adjustment for obstetric and maternal factors, Vietnamese-born women were at greater odds of an unplanned caesarean birth compared to Australian-born women (adjusted odds ratio=1.32, 95% confidence interval=1.25-1.40). These greater odds were also found among the 'standard primiparae' (adjusted odds ratio=1.22, 95% confidence interval=1.07-1.40). CONCLUSION: Factors other than clinical risk appear to predispose Vietnamese-born women to unplanned caesarean birth. These may include intrapartum communication, length of residence and familiarity with care systems, and variations in care practices for Vietnamese women. PMID- 29449156 TI - Stochastic expression of lactate dehydrogenase A induces Escherichia coli persister formation. AB - Bacterial persisters are phenotypic variants that survive the treatment of lethal doses of growth-targeting antibiotics without mutations. Although the mechanism underlying persister formation has been studied for decades, how the persister phenotype is switched on and protects itself from antibiotics has been elusive. In this study, we focused on the lactate dehydrogenase gene (ldhA) that was upregulated in an Escherichia coli persister-enriched population. A survival rate assay using an ldhA-overexpressing strain showed that ldhA expression induced persister formation. To identify ldhA-mediated persister formation at the single cell level, time-lapse microscopy with a microfluidic device was used. Stochastic ldhA expression was found to induce dormancy and tolerance against high-dose ampicillin treatment (500 MUg/ml). To better understand the underlying mechanism, we investigated the relationship between ldhA-mediated persister formation and previously reported persister formation through aerobic metabolism repression. As a result, ldhA expression enhanced the proton motive force (PMF) and ATP synthesis. These findings suggest that ldhA-mediated persister formation pathway is different from previously reported persister formation via repression of aerobic metabolism. PMID- 29449158 TI - The first case of hourglass-like constriction neuropathy of a digital nerve. AB - Neuropathies of digital nerves are an infrequent phenomenon and their causes are most often mechanical. A rare cause of acute neuropathy is hourglass-like fascicular constriction of a nerve due to torsion. Although several cases of hourglass-like constriction have been described in the literature, none to our knowledge involved digital nerves. In this report, we present the first case of hourglass-like constriction of a digital nerve. PMID- 29449159 TI - Agenesis, functional deficiency and the common type of the flexor digitorum superficialis of the little finger: A meta-analysis. AB - Agenesis, functional deficiency and the common type of the flexor digitorum superficialis of the little finger are reported in the literature to be highly variable with significant discrepancy between clinical and cadaveric frequencies. The aim of this systematic review was to generate overall clinical and cadaveric weighted frequencies, along with ancestry-based, side-based, sex-based and laterality-based frequencies. A systematic literature search identified 34 studies including 12,213 forearms/hands that met the inclusion criteria. Functional deficit of the FDS tendon of the little finger was significantly more prevalent among Iranian and Caucasian populations as compared to Indian, East African and Chinese populations. The weighted "clinical" frequency of functional absence of the FDS tendon of the little finger was 7.45%, while prevalence of the common type was 37.5%. The weighted "cadaveric" prevalence of muscle absence of the FDS-5 in the forearm was 2.5% while tendon absence in the hands was nil. An expanded examination technique proved to be the most accurate test for FDS function. In case of injury, inadequate knowledge of different connections or substitutions of the FDS-5 could lead to a total loss of flexion of the little finger. These findings support the hypothesis of a dual origin of the FDS-5 where the muscle portion originates in the forearm, while the tendon portion originates in the hand.

PMID- 29449161 TI - Ultrasound Training in Surgical Critical Care Fellowship: A Survey of Program Directors. AB - OBJECTIVE: Surgical critical care (SCC) fellows are expected to receive training in critical care ultrasound (CCUS) but training is sporadic and there is no standardized curriculum to guide educators. Previous studies show wide variation in CCUS training during fellowship across specialties but SCC has been underrepresented. This study was performed to assess SCC program directors' views regarding CCUS during fellowship training. DESIGN: Adult SCC program directors were surveyed regarding the role of CCUS in fellowship training. This survey assessed how CCUS training was performed, perceived barriers to education, and importance of specific studies. Survey responses were measured using a Likert scale ranging from 5 (strongly agree) to 1 (strongly disagree). SETTING: Web based survey. PARTICIPANTS: Adult Surgical Critical Care Fellowship Program Directors. RESULTS: A total 67 of 108 (62%) SCC program directors responded to the survey. Over 75% felt that CCUS during training should be a priority. Fifteen (24.6%) programs required a specific number of ultrasounds to be performed. Five programs (7.5%) provided no CCUS training at all. Over 75% felt that training in FAST, transthoracic echocardiography, inferior vena cava assessment, and US for procedures (line placement, thoracentesis, and paracentesis) were either important or very important but experience in transesophageal echocardiography, assessment for deep vein thrombosis, and pulmonary US were not important. Lack of time (63.8%) and trained faculty (51.2%) were the most cited barriers to training. CONCLUSIONS: There is a wide variation in how CCUS training is performed during SCC fellowship. SCC programs will need trained faculty, appropriate time allocation, and implementation of a standardized curriculum to provide consistent and high-quality CCUS education during fellowship. PMID- 29449162 TI - Is Video-Based Education an Effective Method in Surgical Education? A Systematic Review. AB - OBJECTIVE: Visual signs draw more attention during the learning process. Video is one of the most effective tool including a lot of visual cues. This systematic review set out to explore the influence of video in surgical education. We reviewed the current evidence for the video-based surgical education methods, discuss the advantages and disadvantages on the teaching of technical and nontechnical surgical skills. METHODS: This systematic review was conducted according to the guidelines defined in the preferred reporting items for systematic reviews and meta-analyses statement. The electronic databases: the Cochrane Library, Medline (PubMED), and ProQuest were searched from their inception to the 30 January 2016. The Medical Subject Headings (MeSH) terms and keywords used were "video," "education," and "surgery." We analyzed all full texts, randomised and nonrandomised clinical trials and observational studies including video-based education methods about any surgery. "Education" means a medical resident's or student's training and teaching process; not patients' education. We did not impose restrictions about language or publication date. RESULTS: A total of nine articles which met inclusion criteria were included. These trials enrolled 507 participants and the total number of participants per trial ranged from 10 to 172. Nearly all of the studies reviewed report significant knowledge gain from video-based education techniques. The findings of this systematic review provide fair to good quality studies to demonstrate significant gains in knowledge compared with traditional teaching. Additional video to simulator exercise or 3D animations has beneficial effects on training time, learning duration, acquisition of surgical skills, and trainee's satisfaction. CONCLUSION: Video-based education has potential for use in surgical education as trainees face significant barriers in their practice. This method is effective according to the recent literature. Video should be used in addition to standard techniques in the surgical education. PMID- 29449163 TI - Orthopaedic Surgery Residency Rotations and Correlation With Orthopaedic In Training Examination Performance. AB - OBJECTIVE: The Orthopaedic In-Training Examination (OITE) is administered annually and is used to assess medical knowledge of orthopedic surgery residents. Beginning in the 2013 to 2014 academic year, the ACGME expanded the postgraduate year (PGY)-1 curriculum from 3 to 6 months of orthopedic surgery rotations. The purpose of this study is to evaluate the effect of increased PGY-1 orthopedic surgery exposure on medical knowledge as measured by the OITE. DESIGN: From 2011 to 2013, 24 PGY-2 residents completed 3 months of PGY-1 orthopedic training (Group 1). From 2014 to 2016, 24 PGY-2 residents completed 6 months of PGY-1 orthopedic training (Group 2). The effect of an initial PGY-2 pediatrics rotation (Sub-group A), compared to a trauma rotation (Sub-group B) was also analyzed. The hypothesis of this study is that Group 2 scores higher on the OITE than Group 1. Raw percentage and overall percentile scores for all PGY-2 residents from 2011 to 2016 for the pediatrics subsection, the trauma subsection, and for the overall OITE test in our program were recorded. Group 1 versus Group 2, and Sub-group A versus Sub-group B were compared (Student's t-test). SETTING: University of Minnesota (Institutional, Tertiary); Gillette Children's Hospital (Institutional, Tertiary); Regions Hospital (Institutional, Tertiary). PARTICIPANTS: 48 PGY-2 residents from 2011 to 2016 were included in the study. RESULTS: Group 2 achieved higher raw and percentile scores on the OITE during their PGY-2 year than Group 1. Sub-group B scored higher than Sub-group A on all OITE subsections and overall. CONCLUSIONS: This study suggests that raw percentage and percentile OITE scores improve with an additional 3 months of orthopedic training in the PGY-1 year. Clinical exposure, specifically in orthopedic trauma, correlates with higher OITE performance in our residency program. PMID- 29449164 TI - Patients Taking beta-Blockers Do Not Require Increased Doses of Epinephrine for Anaphylaxis. AB - BACKGROUND: beta-Blocker use has been associated with increased anaphylaxis severity. OBJECTIVE: We aimed to assess for an association between beta-blocker use and requirement for more than 1 dose of epinephrine for anaphylaxis management. METHODS: We conducted a retrospective observational study of patients seen in our emergency department for anaphylaxis between April 2008 and January 2015. The primary outcome measure was the number of doses of epinephrine. Associations with repeat epinephrine administration (>1 vs <=1 dose of epinephrine) and associations with any epinephrine administration (>0 vs 0 dose) were evaluated using logistic regression models and summarized as odds ratio (OR) and 95% CIs. The study was powered to detect a 10% or greater difference in need for repeat epinephrine administration between patients who were and were not taking beta-blocker medications. RESULTS: Of 789 patient visits with a documented medication history included in the study, 63 (8%) required more than 1 epinephrine dose and 83 (11%) were on beta-blocker therapy. Among patients who required more than 1 epinephrine dose, 8 (13%) were taking a beta-blocker, compared with 75 patients (10%) who received 0 or 1 dose of epinephrine (OR, 1.26; 95% CI, 0.58-2.75). Among patients who required at least 1 epinephrine dose, 41 (9%) were taking a beta-blocker, compared with 42 patients (12%) who received no epinephrine (OR, 0.73; 95% CI, 0.46-1.14). CONCLUSIONS: beta-Blocker use may not be clinically significant with regard to the need for epinephrine dosing among emergency department patients with anaphylaxis. PMID- 29449166 TI - Clinical characteristics and treatment outcomes of pulmonary invasive fungal infection among adult patients with hematological malignancy in a medical centre in Taiwan, 2008-2013. AB - BACKGROUND/PURPOSE: This study was aimed to investigate clinical characteristics and treatment outcomes of pulmonary invasive fungal infection (IFI) among patients with hematological malignancy. METHODS: All patients with hematological malignancy who were treated at a medical centre from 2008 to 2013 were evaluated. Pulmonary IFI was classified according to the European Organization for Research and Treatment of Cancer 2008 consensus. RESULTS: During the study period, 236 (11.3%) of 2083 patients with hematological malignancy were diagnosed as pulmonary IFI, including 41 (17.4%) proven, 75 (31.8%) probable, and 120 (50.8%) possible cases. Among the 116 patients of proven and probable cases of pulmonary IFI, aspergillosis alone (n = 90, 77.6%) was predominant, followed by cryptococcosis alone (n = 9, 7.8%), and mucormycosis (n = 4, 3.4%). The overall incidence of patients with pulmonary IFI was 5.9 per 100 patient-years. The highest incidence (per 100 patient-year) was found in patients with acute myeloid leukaemia (13.7) followed by acute lymphoblastic leukaemia (11.3), and myelodysplastic syndrome/severe aplastic anaemia (6.7). Fourteen (5.9%) of the 236 patients with pulmonary IFI died within 12 weeks after diagnosis of pulmonary IFI. Univariate analysis revealed that elderly age (>65 years) (P = 0.034), lack of response to anti-fungal treatment (P < 0.001), and admission to the intensive care unit (ICU) (P < 0.001) were predictors of poor prognosis. However, only admission to the ICU was an independent predictor of poor prognosis for 12-week mortality (P = 0.022) based on multivariate analysis. CONCLUSION: Patients with acute leukaemia and myelodysplastic syndrome/severe aplastic anaemia were at high risk of pulmonary IFI. PMID- 29449165 TI - Spirometry and Impulse Oscillometry in Preschool Children: Acceptability and Relationship to Maternal Smoking in Pregnancy. AB - BACKGROUND: Comparisons of the technical acceptability of spirometry and impulse oscillometry (IOS) and clinical correlations of the measurements have not been well studied in young children. There are no large studies focused on African American and Hispanic children. OBJECTIVES: We sought to (1) compare the acceptability of spirometry and IOS in 3- to 5-year-old children and (2) examine the relationship of maternal smoking during pregnancy to later lung function. METHODS: Spirometry and IOS were attempted at 4 sites from the Urban Environmental and Childhood Asthma Study birth cohort at ages 3, 4, and 5 years (472, 471, and 479 children, respectively). We measured forced expiratory flow in 0.5 s (forced expiratory volume in 0.5 seconds [FEV0.5]) with spirometry and area of reactance (AX), resistance and reactance at 5 Hz (R5 and X5, respectively) using IOS. RESULTS: Children were more likely to achieve acceptable maneuvers with spirometry than with IOS at age 3 (60% vs 46%, P < .001) and 5 years (89% vs 84%, P = .02). Performance was consistent among the 4 study sites. In children without recurrent wheeze, there were strong trends for higher FEV0.5 and lower R5 and AX over time. Maternal smoking during pregnancy was associated with higher AX at ages 4 and 5 years (P < .01 for both years). There was no significant difference in FEV0.5 between children with and without in utero exposure to smoking. CONCLUSION: There is a higher rate of acceptable maneuvers with spirometry compared with IOS, but IOS may be a better indicator of peripheral airway function in preschool children.

PMID- 29449169 TI - Interaction of the Wnt/beta-catenin and RAS-ERK pathways involving co stabilization of both beta-catenin and RAS plays important roles in the colorectal tumorigenesis. AB - Cancer development is usually driven by multiple genetic and molecular alterations rather than by a single defect. In the human colorectal cancer (CRC), series of mutations of genes are involved in the different stages of tumorigenesis. For example, adenomatous polyposis coli (APC) and KRAS mutations have been known to play roles in the initiation and progression of the tumorigenesis, respectively. However, many studies indicate that mutations of these two genes, which play roles in the Wnt/beta-catenin and RAS-extra-cellular signal regulated kinase (ERK) pathways, respectively, cooperatively interact in the tumorigenesis in several different cancer types including CRC. Both Apc and Kras mutations critically increase number and growth rate of tumors although single mutation of these genes does not significantly enhance the small intestinal tumorigenesis of mice. Both APC and KRAS mutations even result in the liver metastasis with inductions of the cancer stem cells (CSCs) markers in a mice xenograft model. In this review, we are going to describe the history for interaction between the Wnt/beta-catenin and RAS/ERK pathways especially related with CRC, and provide the mechanical basis for the cross-talk between the two pathways. The highlight of the crosstalk involving the stability regulation of RAS protein via the Wnt/beta-catenin signaling which is directly related with the cellular proliferation and transformation will be discussed. Activation status of GSK3beta, a key enzyme involving both beta-catenin and RAS degradations, is regulated by the status of the Wnt/beta-catenin signaling dependent upon extracellular stimuli or intracellular abnormalities of the signaling components. The levels of both beta-catenin and RAS proteins are co-regulated by the Wnt/beta catenin signaling, and these proteins are overexpressed with a positive correlation in the tumor tissues of CRC patients. These results indicate that the elevation of both beta-catenin and RAS proteins is pathologically significant in CRC. In this review, we also will discuss further involvement of the increments of both beta-catenin and RAS especially mutant KRAS in the activation of CSCs and metastasis. Overall, the increments of beta-catenin and RAS especially mutant KRAS by APC loss play important roles in the cooperative tumorigenesis of CRC.

PMID- 29449171 TI - Changes in antimicrobial susceptibility of commonly clinically significant isolates before and after the interventions on surgical prophylactic antibiotics (SPAs) in Shanghai. AB - Surveillances and interventions on antibiotics use have been suggested to improve serious drug-resistance worldwide. Since 2007, our hospital have proposed many measures for regulating surgical prophylactic antibiotics (carbapenems, third gen. cephalosporins, vancomycin, etc.) prescribing practices, like formulary restriction or replacement for surgical prophylactic antibiotics and timely feedback. To assess the impacts on drug-resistance after interventions, we enrolled infected patients in 2006 (pre-intervention period) and 2014 (post intervention period) in a tertiary hospital in Shanghai. Proportions of targeted pathogens were analyzed: methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus spp. (VRE), imipenem-resistant Escherichia coli (IREC), imipenem-resistant Klebsiella pneumoniae (IRKP), imipenem-resistant Acinetobacter baumannii (IRAB) and imipenem-resistant Pseudomonas aeruginosa (IRPA) isolates. Rates of them were estimated and compared between Surgical Department, ICU and Internal Department during two periods. The total proportions of targeted isolates in Surgical Department (62.44%, 2006; 64.09%, 2014) were more than those in ICU (46.13%, 2006; 50.99%, 2014) and in Internal Department (44.54%, 2006; 51.20%, 2014). Only MRSA has decreased significantly (80.48%, 2006; 55.97%, 2014) (p<0.0001). The percentages of VRE and IREC in 3 departments were all <15%, and the slightest change were also both observed in Surgical Department (VRE: 0.76%, 2006; 2.03%, 2014) (IREC: 2.69%, 2006; 2.63%, 2014). The interventions on surgical prophylactic antibiotics can be effective for improving resistance; antimicrobial stewardship must be combined with infection control practices. PMID- 29449172 TI - pMEX01, a 70kb plasmid isolated from Escherichia coli that confers resistance to multiple beta-lactam antibiotics. AB - Multidrug-resistant microorganisms are of great concern to public health. Genetic mobile elements, such as plasmids, are among the most relevant mechanisms by which bacteria achieve this resistance. We obtained an Escherichia coli strain CM6, isolated from cattle presenting severe diarrheic symptoms in the State of Queretaro, Mexico. It was found to contain a 70kb plasmid (pMEX01) with a high similarity to the pHK01-like plasmids that were previously identified and described in Hong Kong. Analysis of the pMEX01 sequence revealed the presence of a blaCTX-M-14 gene, which is responsible for conferring resistance to multiple beta-lactam antibiotics. Several genes putatively involved in the conjugative transfer were also identified on the plasmid. The strain CM6 is of high epidemiological concern because it not only displays resistance to multiple beta lactam antibiotics but also to other kinds of antibiotics. PMID- 29449173 TI - Exopolysaccharide production from Bacillus velezensis KY471306 using statistical experimental design. AB - Exopolysaccharide (EPS) biopolymers produced by microorganisms play a crucial role in the environment such as health and bio-nanotechnology sectors, gelling agents in food and cosmetic industries in addition to bio-flocculants in the environmental sector as they are degradable, nontoxic. This study focuses on the improvement of EPS production through manipulation of different culture and environmental conditions using response surface methodology (RSM). Plackett Burman design indicated that; molasses, yeast extract and incubation temperature are the most effective parameters. Box-Behnken RSM indicated that; the optimum concentration for each parameter was 12% (w/v) for molasses, 6g/L yeast extract and 30 degrees C for incubation temperature. The most potent bacterial isolate was identified as Bacillus velezensis KY498625. After production, EPS was extracted, purified using DEAE-cellulose, identified using Fourier transform infrared (FTIR), gel permeation chromatography (GPC) and gas chromatography-mass spectroscopy (GC-MS). The result indicated that; it has molecular weight 1.14*105D consisting of glucose, mannose and galactose. PMID- 29449174 TI - Survival of Salmonella spp. in minced meat packaged under vacuum and modified atmosphere. AB - The effect of different modified atmosphere packaging regimes on the behavior of Salmonella spp. on minced meat was studied. Minced meat was experimentally contaminated with a Salmonella spp. cocktail (S. Enteritidis, S. Typhimurium, S. Infantis and S. Arizonae), packaged under vacuum or modified atmosphere with initial headspaces containing 20%O2/50%CO2/30%N2 and 20%O2/30%CO2/50%N2) and stored at 3+/-1 degrees C for 12 days. Samples were analyzed for Salmonella spp., viable and lactic acid bacteria count every third day. Salmonella spp. counts decreased during storage in all packaging types, with reductions of about 1.5logCFU/g. A significant difference (p<0.01) was noted between Salmonella spp. counts in meat packaged in vacuum and modified atmospheres, although there was no significant difference in Salmonella spp. count between meat packaged in 50%CO2, and meat packaged in 30%CO2. At the end of the study, there were significant differences (p<0.01; p<0.05) in total viable and lactic acid bacterial counts between meat packaged in vacuum and modified atmosphere, and the lowest counts were noted in meat packaged in modified atmosphere with 50%CO2.

AB - Escalating burden of antibiotic resistance that has reached new heights present a grave concern to mankind. As the problem is no longer confined to clinics, we hereby report identification of a pandrug resistant Escherichia coli isolate from heavily polluted Delhi stretch of river Yamuna, India. E. coli MRC11 was found sensitive only to tobramycin against 21 antibiotics tested, with minimum inhibitory concentration values >256MUg/mL for amoxicillin, carbenicillin, aztreonam, ceftazidime and cefotaxime. Addition of certain heavy metals at higher concentrations were ineffective in increasing susceptibility of E. coli MRC11 to antibiotics. Withstanding sub-optimal concentration of cefotaxime (10MUg/mL) and mercuric chloride (2MUg/mL), and also resistance to their combinatorial use, indicates better adaptability in heavily polluted environment through clustering and expression of resistance genes. Interestingly, E. coli MRC11 harbours two different variants of blaTEM (blaTEM-116 and blaTEM-1 with and without extended spectrum activity, respectively), in addition to mer operon (merB, merP and merT) genes. Studies employing conjugation, confirmed localization of blaTEM-116, merP and merT genes on the conjugative plasmid. Understanding potentialities of such isolates will help in determining risk factors attributing pandrug resistance and strengthening strategic development of new and effective antimicrobial agents.

AB - An increasing production of natural rubber (NR) products has led to major challenges in waste management. In this study, the degradation of rubber latex gloves in a mineral salt medium (MSM) using a bacterial consortium, a mixed culture of the selected bacteria and a pure culture were studied. The highest 18% weight loss of the rubber gloves were detected after incubated with the mixed culture. The increased viable cell counts over incubation time indicated that cells used rubber gloves as sole carbon source leading to the degradation of the polymer. The growth behavior of NR-degrading bacteria on the latex gloves surface was investigated using the scanning electron microscope (SEM). The occurrence of the aldehyde groups in the degradation products was observed by Fourier Transform Infrared Spectroscopy analysis. Rhodococcus pyridinivorans strain F5 gave the highest weight loss of rubber gloves among the isolated strain and posses latex clearing protein encoded by lcp gene. The mixed culture of the selected strains showed the potential in degrading rubber within 30 days and is considered to be used efficiently for rubber product degradation. This is the first report to demonstrate a strong ability to degrade rubber by Rhodococcus pyridinivorans.

PMID- 29449177 TI - Cloning and expression of an endoglucanase gene from the thermotolerant fungus Aspergillus fumigatus DBiNU-1 in Kluyveromyces lactis. AB - An intronless endoglucanase from thermotolerant Aspergillus fumigatus DBINU-1 was cloned, characterized and expressed in the yeast Kluyveromyces lactis. The full length open reading frame of the endoglucanase gene from A. fumigatus DBiNU-1, designated Cel7, was 1383 nucleotides in length and encoded a protein of 460 amino acid residues. The predicted molecular weight and the isoelectric point of the A. fumigatus Cel7 gene product were 48.19kDa and 5.03, respectively. A catalytic domain in the N-terminal region and a fungal type cellulose-binding domain/module in the C-terminal region were detected in the predicted polypeptide sequences. Furthermore, a signal peptide with 20 amino acid residues at the N terminus was also detected in the deduced amino acid sequences of the endoglucanase from A. fumigatus DBiNU-1. The endoglucanase from A. fumigatus DBiNU-1 was successfully expressed in K. lactis, and the purified recombinant enzyme exhibited its maximum activity at pH 5.0 and 60 degrees C. The enzyme was very stable in a pH range from 4.0 to 8.0 and a temperature range from 30 to 60 degrees C. These features make it suitable for application in the paper, biofuel, and other chemical production industries that use cellulosic materials. PMID- 29449179 TI - The end of family therapy for self-harm, or a new beginning? PMID- 29449180 TI - Effectiveness of systemic family therapy versus treatment as usual for young people after self-harm: a pragmatic, phase 3, multicentre, randomised controlled trial. AB - BACKGROUND: Self-harm in adolescents is common and repetition occurs in a high proportion of these cases. Scarce evidence exists for effectiveness of interventions to reduce self-harm. METHODS: This pragmatic, multicentre, randomised, controlled trial of family therapy versus treatment as usual was done at 40 UK Child and Adolescent Mental Health Services (CAMHS) centres. We recruited young people aged 11-17 years who had self-harmed at least twice and presented to CAMHS after self-harm. Participants were randomly assigned (1:1) to receive manualised family therapy delivered by trained and supervised family therapists or treatment as usual by local CAMHS. Participants and therapists were aware of treatment allocation; researchers were masked. The primary outcome was hospital attendance for repetition of self-harm in the 18 months after group assignment. Primary and safety analyses were done in the intention-to-treat population. The trial is registered at the ISRCTN registry, number ISRCTN59793150. FINDINGS: Between Nov 23, 2009, and Dec 31, 2013, 3554 young people were screened and 832 eligible young people consented to participation and were randomly assigned to receive family therapy (n=415) or treatment as usual (n=417). Primary outcome data were available for 795 (96%) participants. Numbers of hospital attendances for repeat self-harm events were not significantly different between the groups (118 [28%] in the family therapy group vs 103 [25%] in the treatment as usual group; hazard ratio 1.14 [95% CI 0.87-1.49] p=0.33). Similar numbers of adverse events occurred in both groups (787 in the family therapy group vs 847 in the treatment as usual group). INTERPRETATION: For adolescents referred to CAMHS after self-harm, having self-harmed at least once before, our family therapy intervention conferred no benefits over treatment as usual in reducing subsequent hospital attendance for self-harm. Clinicians are therefore still unable to recommend a clear, evidence-based intervention to reduce repeated self-harm in adolescents.

PMID- 29449181 TI - Roux en Y gastric bypass hypoglycemia resolves with gastric feeding or reversal: Confirming a non-pancreatic etiology. AB - OBJECTIVE: Postprandial hypoglycemia is an infrequent but disabling complication of Roux-en-Y gastric bypass (RYGB) surgery. Controversy still exists as to whether the postprandial hyperinsulinemia observed is due to inherent changes in pancreatic beta-cell mass or function or to reversible alterations caused by RYGB anatomy. We aimed to determine if gastric feeding or reversal of RYGB would normalize postprandial glucose and hormone excursions in patients with symptomatic hypoglycemia. METHODS: We completed a prospective study of six patients with severe symptomatic RYGB hypoglycemia who underwent RYGB reversal. An additional subject without hypoglycemia who underwent RYGB reversal was also studied prospectively. Mixed meal tolerance testing (MTT) was done orally (RYGB anatomy), via gastrostomy tube in the excluded stomach in the setting of RYGB, and several months after RYGB reversal. RESULTS: All subjects reported symptomatic improvement of hypoglycemia after reversal of RYGB. Weight gain after reversal was moderate and variable. Postprandial glucose, insulin, and GLP-1 excursions were significantly diminished with gastric feeding and after reversal. Insulin secretion changed proportional to glucose levels and insulin clearance increased after reversal. Glucagon/insulin ratios were similar throughout study. We further compared the impact of modified sleeve gastrectomy reversal surgery to those with restoration of complete stomach and found no significant differences in weight regain or in postprandial glucose or hormone levels. CONCLUSIONS: Reversal of RYGB is an effective treatment option for severe postprandial hypoglycemia. The pathophysiology of this disorder is primarily due to RYGB anatomy resulting in altered glucose, gut, and pancreatic hormone levels and decreased insulin clearance, rather than inherent beta-cell hyperplasia or hyperfunction.

PMID- 29449183 TI - Altered resting-state voxel-level whole-brain functional connectivity in depressed Parkinson's disease. AB - BACKGROUND: Depression is one of the most common non-motor symptoms in Parkinson's disease (PD), but its pathogenesis is still not very clear. Recently, degree centrality, a voxel-level whole-brain functional connectivity (FC) analysis of resting-state functional magnetic resonance imaging, has provided the most promising way to explore the neural network mechanisms underlying depressed PD. METHODS: Degree centrality, voxel-wise image and clinical symptoms correlation and secondary seed-based FC analyses were performed in twenty-seven drug-naive, early stage depressed PD patients, 27 non-depressed PD patients and 27 healthy controls (HCs) to reveal voxel-level whole-brain FC changes in depressed PD. RESULTS: Compared with the HCs, depressed PD and non-depressed PD patients shared similar brain degree centrality abnormalities mainly in the basal ganglia, insular cortex, motor cortices, default mode network, prefrontal gyrus and the cerebellum. However, compared with non-depressed PD, depressed PD showed degree centrality abnormalities in the right middle prefrontal gyrus, anterior cingulate cortices, supplementary motor cortices and cerebellum lobule VI. The right middle prefrontal gyrus degree centrality abnormalities were correlated with the clinical depression severity, and using it as a seed, a secondary seed based FC analysis further revealed the FC changes in the anterior cingulate cortices and the cerebellum lobule VI. CONCLUSIONS: Our findings revealed that dysfunction in extensive brain areas were involved in depressed PD, and among these regions, the right middle prefrontal gyrus, anterior cingulate cortices and the cerebellum may pose as pathogenesis hubs underlying depressed PD. PMID- 29449184 TI - Relation of overactive bladder with motor symptoms and dopamine transporter imaging in drug-naive Parkinson's disease. AB - OBJECTIVES: The aim of the present study was to determine the relation of urinary dysfunction with motor symptoms and nigrostriatal neuron loss in drug-naive patients with Parkinson's disease (PD). We therefore examined the relation of overactive bladder (OAB) symptoms with motor symptoms and striatal dopamine transporter (DAT) binding measured by [123-Iodine]-fluoropropyl-2beta carbomethoxy-3beta-(4-iodophenylnortropane) dopamine transporter single-photon emission computed tomography (123I-FP-CIT SPECT). PATIENTS AND METHODS: Thirty one untreated PD patients (12 men and 19 women with a mean age of 71.2 +/- 6.7 years) were included in this study. Patients were evaluated with overactive bladder symptom score (OABSS) and divided into an OAB group and Non-OAB group. They underwent clinical assessments and 123I-FP-CIT SPECT imaging. Motor symptoms were assessed using Unified Parkinson's Disease Rating Scale (UPDRS). RESULTS: The results showed that UPDRS motor score (p = 0.01) and akinetic-rigid score (p = 0.002) were higher and that striatal DAT availability (p = 0.01) was lower in the OAB group than in the Non-OAB group. However, tremor score, age, and duration of PD showed no significant differences between the OAB group and Non-OAB group. CONCLUSIONS: Urinary dysfunction in untreated PD is related with increase in motor symptoms (especially bradykinesia and axial symptoms) and reduction of striatal DAT availability. PMID- 29449185 TI - Association of coffee consumption and non-motor symptoms in drug-naive, early stage Parkinson's disease. AB - OBJECTIVE: Coffee consumption has an inverse association with the risk of Parkinson's disease (PD). The aim of this study was to investigate the association between coffee consumption and non-motor symptoms (NMSs) in patients with PD. METHODS: In this cross-sectional study, we included 196 early-stage, treatment-naive PD patients. Coffee consumption history was obtained via semi structured interviews. NMSs were assessed using the Non-Motor Symptom assessment scale (NMSS). RESULTS: Of the 196 patients with PD, 136 (69.3%) were categorized as coffee drinkers and 60 (30.6%) were non-drinkers. Coffee drinkers were younger, predominantly male, were younger in age at symptom onset, had lower Unified Parkinson's Disease Rating Scale motor and Beck Depression Inventory scores, and higher Mini-Mental State Examination scores than non-coffee drinkers. After adjustment, coffee drinking was significantly inversely associated with the prevalence of lack of motivation, anhedonia, and lack of pleasure, which were less frequent in coffee drinkers. Total NMSS scores were lower in coffee drinkers than in non-drinkers (p = 0.047). In particular, coffee drinking was significantly associated with a reduced severity of the mood/cognition domain of NMSS (p = 0.003). After correcting for multiple testing, there were no significant differences in the prevalence of NMSs, but there were significant differences in the severity of NMSs between coffee drinkers and non-drinkers. CONCLUSION: There is a negative association between coffee consumption and the severity of the mood/cognition domain of NMSS in patients with PD. Clinicians should consider the history of coffee consumption in the assessment of NMSs in PD. PMID- 29449186 TI - The reorganization of functional architecture in the early-stages of Parkinson's disease. AB - INTRODUCTION: The study aim was to identify longitudinal abnormalities of functional connectivity and its relation with motor disability in early to moderately advanced stages of Parkinson's disease patients. METHODS: 3.0T structural and resting-state functional MRI was performed in healthy subjects (n = 16) and Parkinson's disease patients (n = 16) with mean disease duration of 2.2 +/- 1.2 years at baseline with a clinical follow-up of 1.5 +/- 0.3 years. Resting state fMRI analysis included region-to-region connectivity in correlation with UPDRS-III scores and computation of Global Efficiency and Degree Centrality. RESULTS: At baseline, patients' connectivity increased between the cerebellum and somatomotor network, and decreased between motor regions (Rolandic operculum, precentral gyrus, supplementary motor area, postcentral gyrus) and cingulate connectivity. At 1.5 years follow-up, connectivity remained altered in the same regions identified at baseline. The cerebellum showed additional hyperconnectivity within itself and to the caudate nucleus, thalamus and amygdala compared to controls. These differences correlated with UPDRS-III scores. Seed based connectivity revealed increased involvement of the default mode network with precentral gyrus in patients at follow-up investigation. CONCLUSION: Resting state fMRI identified marked disturbances of the overall architecture of connectivity in Parkinson's disease. The noted alterations in cortical motor areas were associated with cerebellar hyperconnectivity in early to moderately advanced stages of Parkinson's disease suggesting ongoing attempts of recovery and compensatory mechanism for affected functions. The potential to identify connectivity alterations in regions related to both motor and attentional functions requires further evaluation as an objective marker to monitor disease progression, and medical, as well as surgical interventions. PMID- 29449187 TI - Cortical atrophy patterns in early Parkinson's disease patients using hierarchical cluster analysis. AB - INTRODUCTION: Cortical brain atrophy detectable with MRI in non-demented advanced Parkinson's disease (PD) is well characterized, but its presence in early disease stages is still under debate. We aimed to investigate cortical atrophy patterns in a large sample of early untreated PD patients using a hypothesis-free data driven approach. METHODS: Seventy-seven de novo PD patients and 50 controls from the Parkinson's Progression Marker Initiative database with T1-weighted images in a 3-tesla Siemens scanner were included in this study. Mean cortical thickness was extracted from 360 cortical areas defined by the Human Connectome Project Multi-Modal Parcellation version 1.0, and a hierarchical cluster analysis was performed using Ward's linkage method. A general linear model with cortical thickness data was then used to compare clustering groups using FreeSurfer software. RESULTS: We identified two patterns of cortical atrophy. Compared with controls, patients grouped in pattern 1 (n = 33) were characterized by cortical thinning in bilateral orbitofrontal, anterior cingulate, and lateral and medial anterior temporal gyri. Patients in pattern 2 (n = 44) showed cortical thinning in bilateral occipital gyrus, cuneus, superior parietal gyrus, and left postcentral gyrus, and they showed neuropsychological impairment in memory and other cognitive domains. CONCLUSIONS: Even in the early stages of PD, there is evidence of cortical brain atrophy. Neuroimaging clustering analysis is able to detect two subgroups of cortical thinning, one with mainly anterior atrophy, and the other with posterior predominance and worse cognitive performance. PMID- 29449188 TI - Novel homozygous variants in ATCAY, MCOLN1, and SACS in complex neurological disorders. AB - BACKGROUND: Neurological disorders comprise a large group of clinically and genetically heterogeneous disorders, many of which have a genetic cause. In addition to a detailed neurological examination, exome sequencing is being increasingly used as a complementary diagnostic tool to identify the underlying genetic cause in patients with unclear, supposedly genetically determined disorders. OBJECTIVE: To identify the genetic cause of a complex movement disorder in five consanguineous Pakistani families. METHODS: We included five consanguineous Pakistani families with complex recessively inherited movement disorders. Clinical investigation including videotaping was carried out in a total of 59 family members (4-21 per family) and MRI in six patients. Exome sequencing was performed in 4-5 family members per pedigree to explore the underlying genetic cause. RESULTS: Patients presented a wide spectrum of neurological symptoms including ataxia and/or dystonia. We identified three novel homozygous, segregating variants in ATCAY (p.Pro200Profs*20), MCOLN1 (p.Ile184Thr), and SACS (p.Asn3040Lysfs*4) in three of the families. Thus, we were able to identify the likely cause of the disease in a considerable number of families (60%) with the relatively simple and nowadays widely available method of exome sequencing. Of note, close collaboration of neurologists and geneticists was instrumental for proper data interpretation. CONCLUSIONS: We expand the phenotypic, genotypic, and ethnical spectrum of mutations in these genes. Our findings alert neurologists that rare genetic causes should be considered in complex phenotypes regardless of ethnicity.

PMID- 29449189 TI - Adjuvant chemoradiotherapy versus radiotherapy alone for women with high-risk endometrial cancer (PORTEC-3): final results of an international, open-label, multicentre, randomised, phase 3 trial. AB - BACKGROUND: Although women with endometrial cancer generally have a favourable prognosis, those with high-risk disease features are at increased risk of recurrence. The PORTEC-3 trial was initiated to investigate the benefit of adjuvant chemotherapy during and after radiotherapy (chemoradiotherapy) versus pelvic radiotherapy alone for women with high-risk endometrial cancer. METHODS: PORTEC-3 was an open-label, international, randomised, phase 3 trial involving 103 centres in six clinical trials collaborating in the Gynaecological Cancer Intergroup. Eligible women had high-risk endometrial cancer with FIGO 2009 stage I, endometrioid-type grade 3 with deep myometrial invasion or lymph-vascular space invasion (or both), endometrioid-type stage II or III, or stage I to III with serous or clear cell histology. Women were randomly assigned (1:1) to receive radiotherapy alone (48.6 Gy in 1.8 Gy fractions given on 5 days per week) or radiotherapy and chemotherapy (consisting of two cycles of cisplatin 50 mg/m2 given during radiotherapy, followed by four cycles of carboplatin AUC5 and paclitaxel 175 mg/m2) using a biased-coin minimisation procedure with stratification for participating centre, lymphadenectomy, stage of cancer, and histological type. The co-primary endpoints were overall survival and failure free survival. We used the Kaplan-Meier method, log-rank test, and Cox regression analysis for final analysis by intention to treat and adjusted for stratification factors. The study was closed on Dec 20, 2013, after achieving complete accrual; follow-up is ongoing. PORTEC-3 is registered with ISRCTN, number ISRCTN14387080, and ClinicalTrials.gov, number NCT00411138. RESULTS: 686 women were enrolled between Nov 23, 2006, and Dec 20, 2013. 660 eligible patients were included in the final analysis, of whom 330 were assigned to chemoradiotherapy and 330 were assigned to radiotherapy. Median follow-up was 60.2 months (IQR 48.1-73.1). 5 year overall survival was 81.8% (95% CI 77.5-86.2) with chemoradiotherapy versus 76.7% (72.1-81.6) with radiotherapy (adjusted hazard ratio [HR] 0.76, 95% CI 0.54 1.06; p=0.11); 5-year failure-free survival was 75.5% (95% CI 70.3-79.9) versus 68.6% (63.1-73.4; HR 0.71, 95% CI 0.53-0.95; p=0.022). Grade 3 or worse adverse events during treatment occurred in 198 (60%) of 330 who received chemoradiotherapy versus 41 (12%) of 330 patients who received radiotherapy (p<0.0001). Neuropathy (grade 2 or worse) persisted significantly more often after chemoradiotherapy than after radiotherapy (20 [8%] women vs one [1%] at 3 years; p<0.0001). Most deaths were due to endometrial cancer; in four patients (two in each group), the cause of death was uncertain. One death in the radiotherapy group was due to either disease progression or late treatment complications; three deaths (two in the chemoradiotherapy group and one in the radiotherapy group) were due to either intercurrent disease or late treatment related toxicity. INTERPRETATION: Adjuvant chemotherapy given during and after radiotherapy for high-risk endometrial cancer did not improve 5-year overall survival, although it did increase failure-free survival. Women with high-risk endometrial cancer should be individually counselled about this combined treatment. Continued follow-up is needed to evaluate long-term survival.

PMID- 29449192 TI - Association of body-mass index and outcomes in patients with metastatic melanoma treated with targeted therapy, immunotherapy, or chemotherapy: a retrospective, multicohort analysis. AB - BACKGROUND: Obesity has been linked to increased mortality in several cancer types; however, the relation between obesity and survival outcomes in metastatic melanoma is unknown. The aim of this study was to examine the association between body-mass index (BMI) and progression-free survival or overall survival in patients with metastatic melanoma who received targeted therapy, immunotherapy, or chemotherapy. METHODS: This retrospective study analysed independent cohorts of patients with metastatic melanoma assigned to treatment with targeted therapy, immunotherapy, or chemotherapy in randomised clinical trials and one retrospective study of patients treated with immunotherapy. Patients were classified according to BMI, following the WHO definitions, as underweight, normal, overweight, or obese. Patients without BMI and underweight patients were excluded. The primary outcomes were the associations between BMI and progression free survival or overall survival, stratified by treatment type and sex. We did multivariable analyses in the independent cohorts, and combined adjusted hazard ratios in a mixed-effects meta-analysis to provide a precise estimate of the association between BMI and survival outcomes; heterogeneity was assessed with meta-regression analyses. Analyses were done on the predefined intention-to-treat population in the randomised controlled trials and on all patients included in the retrospective study. FINDINGS: The six cohorts consisted of a total of 2046 patients with metastatic melanoma treated with targeted therapy, immunotherapy, or chemotherapy between Aug 8, 2006, and Jan 15, 2016. 1918 patients were included in the analysis. Two cohorts containing patients from randomised controlled trials treated with targeted therapy (dabrafenib plus trametinib [n=599] and vemurafenib plus cobimetinib [n=240]), two cohorts containing patients treated with immunotherapy (one randomised controlled trial of ipilimumab plus dacarbazine [n=207] and a retrospective cohort treated with pembrolizumab, nivolumab, or atezolizumab [n=331]), and two cohorts containing patients treated with chemotherapy (two randomised controlled trials of dacarbazine [n=320 and n=221]) were classified according to BMI as normal (694 [36%] patients), overweight (711 [37%]), or obese (513 [27%]). In the pooled analysis, obesity, compared with normal BMI, was associated with improved survival in patients with metastatic melanoma (average adjusted hazard ratio [HR] 0.77 [95% CI 0.66-0.90] for progression-free survival and 0.74 [0.58-0.95] for overall survival). The survival benefit associated with obesity was restricted to patients treated with targeted therapy (HR 0.72 [0.57-0.91] for progression-free survival and 0.60 [0.45-0.79] for overall survival) and immunotherapy (HR 0.75 [0.56-1.00] and 0.64 [0.47-0.86]). No associations were observed with chemotherapy (HR 0.87 [0.65-1.17, pinteraction=0.61] for progression-free survival and 1.03 [0.80-1.34, pinteraction=0.01] for overall survival). The association of BMI with overall survival for patients treated with targeted and immune therapies differed by sex, with inverse associations in men (HR 0.53 [0.40 0.70]), but no associations observed in women (HR 0.85 [0.61-1.18, pinteraction=0.03]). INTERPRETATION: Our results suggest that in patients with metastatic melanoma, obesity is associated with improved progression-free survival and overall survival compared with those outcomes in patients with normal BMI, and that this association is mainly seen in male patients treated with targeted or immune therapy. These results have implications for the design of future clinical trials for patients with metastatic melanoma and the magnitude of the benefit found supports further investigation of the underlying mechanism of these associations.

PMID- 29449193 TI - Phase I Trial of Intrathecal Mesenchymal Stem Cell-derived Neural Progenitors in Progressive Multiple Sclerosis. AB - BACKGROUND: Multiple sclerosis (MS) is an immune-mediated demyelinating disease of the central nervous system and is one of the leading causes of disability in young adults. Cell therapy is emerging as a therapeutic strategy to promote repair and regeneration in patients with disability associated with progressive MS. METHODS: We conducted a phase I open-label clinical trial investigating the safety and tolerability of autologous bone marrow mesenchymal stem cell-derived neural progenitor (MSC-NP) treatment in 20 patients with progressive MS. MSC-NPs were administered intrathecally (IT) in three separate doses of up to 1 * 107 cells per dose, spaced three months apart. The primary endpoint was to assess safety and tolerability of the treatment. Expanded disability status scale (EDSS), timed 25-ft walk (T25FW), muscle strength, and urodynamic testing were used to evaluate treatment response. This trial is registered with ClinicalTrials.gov, number NCT01933802. FINDINGS: IT MSC-NP treatment was safe and well tolerated. The 20 enrolled subjects completed all 60 planned treatments without serious adverse effects. Minor adverse events included transient fever and mild headaches usually resolving in <24 h. Post-treatment disability score analysis demonstrated improved median EDSS suggesting possible efficacy. Positive trends were more frequently observed in the subset of SPMS patients and in ambulatory subjects (EDSS <= 6.5). In addition, 70% and 50% of the subjects demonstrated improved muscle strength and bladder function, respectively, following IT MSC-NP treatment. INTERPRETATION: The possible reversal of disability that was observed in a subset of patients warrants a larger phase II placebo-controlled study to establish efficacy of IT MSC-NP treatment in patients with MS.

PMID- 29449196 TI - Clinical predictors of successful vaginal myomectomy for prolapsed pedunculated uterine leiomyoma AB - Objective: Uterine leiomyomas are the most common pelvic tumor in women. The calculated prevalence of prolapsed pedunculated leiomyoma was 2.5% in patients who underwent surgery. Although vaginal removal is safe and effective, hysterectomy demand is questionable. We aimed to analyze the association between patient characteristics, clinical features of prolapsed pedunculated submucosal leiomyoma, and the probability of successful vaginal myomectomy. Material and Methods: This study was conducted in 35 women who presented with prolapsed pedunculated uterine leiomyoma. Patients were grouped according to the treatment procedure, either vaginal myomectomy or hysterectomy. Results: Hysterectomy was performed in 14 patients and vaginal myomectomy was performed in 21 women. The mean ages and menopausal status were similar. Parity was higher in the hysterectomy group (p=0.02). The preoperative hematocrit value of patients undergoing vaginal myomectomy was significantly lower (p=0.04). There was no significant difference between the groups regarding the largest leiomyoma diameter. However, the median calculated leiomyoma volume was lower in the vaginal myomectomy group (p=0.04). None of the variables were independently associated with successful vaginal myomectomy on multivariable logistic regression analysis. Conclusion: The feasibility and choice of vaginal myomectomy is associated with low parity, absence of coexisting leiomyoma, high volume of leiomyoma estimated via ultrasound measurement, and severe anemia. PMID- 29449194 TI - Prostaglandin D2 Receptor DP1 Antibodies Predict Vaccine-induced and Spontaneous Narcolepsy Type 1: Large-scale Study of Antibody Profiling. AB - BACKGROUND: Neuropathological findings support an autoimmune etiology as an underlying factor for loss of orexin-producing neurons in spontaneous narcolepsy type 1 (narcolepsy with cataplexy; sNT1) as well as in Pandemrix influenza vaccine-induced narcolepsy type 1 (Pdmx-NT1). The precise molecular target or antigens for the immune response have, however, remained elusive. METHODS: Here we have performed a comprehensive antigenic repertoire analysis of sera using the next-generation phage display method - mimotope variation analysis (MVA). Samples from 64 children and adolescents were analyzed: 10 with Pdmx-NT1, 6 with sNT1, 16 Pandemrix-vaccinated, 16 H1N1 infected, and 16 unvaccinated healthy individuals. The diagnosis of NT1 was defined by the American Academy of Sleep Medicine international criteria of sleep disorders v3. FINDINGS: Our data showed that although the immunoprofiles toward vaccination were generally similar in study groups, there were also striking differences in immunoprofiles between sNT1 and Pdmx-NT1 groups as compared with controls. Prominent immune response was observed to a peptide epitope derived from prostaglandin D2 receptor (DP1), as well as peptides homologous to B cell lymphoma 6 protein. Further validation confirmed that these can act as true antigenic targets in discriminating NT1 diseased along with a novel epitope of hemagglutinin of H1N1 to delineate exposure to H1N1. INTERPRETATION: We propose that DP1 is a novel molecular target of autoimmune response and presents a potential diagnostic biomarker for NT1. DP1 is involved in the regulation of non-rapid eye movement (NREM) sleep and thus alterations in its functions could contribute to the disturbed sleep regulation in NT1 that warrants further studies. Together our results also show that MVA is a helpful method for finding novel peptide antigens to classify human autoimmune diseases, possibly facilitating the design of better therapies. PMID- 29449195 TI - Neutrophil Microvesicles from Healthy Control and Rheumatoid Arthritis Patients Prevent the Inflammatory Activation of Macrophages. AB - Microvesicles (MVs) are emerging as a novel means to enact cell-to-cell communication in inflammation. Here, we aimed to ascertain the ability of neutrophil-derived MVs to modulate target cell behaviour, the focus being the macrophage. MVs were generated in response to tumour necrosis factor-alpha, from healthy control neutrophils or those from rheumatoid arthritis patients. MVs were used to stimulate human monocyte-derived macrophages in vitro, or administered intra-articularly in the K/BxN mouse model of arthritis. A macrophage/fibroblast like synoviocyte co-culture system was used to study the effects of vesicles on the crosstalk between these cells. We demonstrate a direct role for phosphatidylserine and annexin-A1 exposed by the MVs to counteract classical activation of the macrophages, and promote the release of transforming growth factor-beta, respectively. Classically-activated macrophages exposed to neutrophil MVs no longer activated fibroblast-like synoviocytes in subsequent co culture settings. Finally, intra-articular administration of neutrophil MVs from rheumatoid arthritis patients in arthritic mice affected the phenotype of joint macrophages. Altogether these data, with the identification of specific MV determinants, open new opportunities to modulate on-going inflammation in the synovia - mainly by affecting macrophage polarization and potentially also fibroblast-like synoviocytes - through the delivery of autologous or heterologous MVs produced from neutrophils.

In humans, it is a very rare pathogen which colonizes the digestive tract, and its utility has been linked to the treatment and prevention of diarrhea associated with Clostridium difficile. CASE REPORT: A 27-year-old male, victim of aggressive, blunt trauma with a 4-day history of symptoms was admitted to our surgery unit. Abdominal sonography revealed peritoneal fluid in all spaces with fibrin. We performed laparotomy and observed perforations on the ileum and general peritonitis with pus. Following surgery, patient was admitted to the intensive care unit with septic shock. The antibiogram from the peritoneal liquid revealed S. putrefaciens and S. cerevisiae. CONCLUSION: Although very rare, S. putrefaciens and S. cerevisiae may colonize in the peritoneum after blunt abdominal trauma. PMID- 29449199 TI - Implementation of Digital Awareness Strategies to Engage Patients and Providers in a Lung Cancer Screening Program: Retrospective Study. AB - BACKGROUND: Lung cancer is the leading cause of cancer-related deaths in the United States. Despite mandated insurance coverage for eligible patients, lung cancer screening rates remain low. Digital platforms, including social media, provide a potentially valuable tool to enhance health promotion and patient engagement related to lung cancer screening (LCS). OBJECTIVE: The aim was to assess the effectiveness of LCS digital awareness campaigns on utilization of low dose computed tomography (LDCT) and visits to institutional online educational content. METHODS: A pay-per-click campaign utilizing Google and Facebook targeted adults aged 55 years and older and caregivers aged 18 years and older (eg, spouses, adult children) with LCS content during a 20-week intervention period from May to September 2016. A concurrent pay-per-click campaign using LinkedIn and Twitter targeted health care providers with LCS content. Geographic target radius was within 60 miles of an academic medical center. Social media data included aggregate demographics and click-through rates (CTRs). Primary outcome measures were visits to institutional Web pages and scheduled LDCT exams. Study period was 20 weeks before, during, and after the digital awareness campaigns. RESULTS: Weekly visits to the institutional LCS Web pages were significantly higher during the digital awareness campaigns compared to the 20-week period prior to implementation (mean 823.9, SD 905.8 vs mean 51, SD 22.3, P=.001). The patient digital awareness campaign surpassed industry standard CTRs on Google (5.85%, 1108/18,955 vs 1.8%) and Facebook (2.59%, 47,750/1,846,070 vs 0.8%). The provider digital awareness campaign surpassed industry standard CTR on LinkedIn (1.1%, 630/57,079 vs 0.3%) but not Twitter (0.19%, 1139/587,133 vs 0.25%). Mean scheduled LDCT exam volumes per week before, during, and after the digital awareness campaigns were 17.4 (SD 7.5), 20.4 (SD 5.4), and 26.2 (SD 6.4), respectively, with the difference between the mean number of scheduled exams after the digital awareness campaigns and the number of exams scheduled before and after the digital awareness campaigns being statistically significant (P<.001). CONCLUSIONS: Implementation of the LCS digital awareness campaigns was associated with increased visits to institutional educational Web pages and scheduled LDCT exams. Digital platforms are an important tool to enhance health promotion activities and engagement with patients and providers. PMID- 29449200 TI - mHealth Technology and Nurse Health Coaching to Improve Health in Diabetes: Protocol for a Randomized Controlled Trial. AB - BACKGROUND: Chronic diseases, including diabetes mellitus, are the leading cause of mortality and disability in the United States. Current solutions focus primarily on diagnosis and pharmacological treatment, yet there is increasing evidence that patient-centered models of care are more successful in improving and addressing chronic disease outcomes. OBJECTIVE: The objective of this clinical trial is to evaluate the impact of a mobile health (mHealth) enabled nurse health coaching intervention on self-efficacy among adults with type-2 diabetes mellitus. METHODS: A randomized controlled trial was conducted at an academic health system in Northern California. A total of 300 participants with type-2 diabetes were scheduled to be enrolled through three primary care clinics. Participants were randomized to either usual care or intervention. All participants received training on use of the health system patient portal. Participants in the intervention arm received six scheduled health-coaching telephone calls with a registered nurse and were provided with an activity tracker and mobile application that integrated data into the electronic health record (EHR) to track their daily activity and health behavior decisions. All participants completed a baseline survey and follow-up surveys at 3 and 9 months. Primary and secondary outcomes include diabetes self-efficacy, hemoglobin A1c (HbA1c), and quality of life measures. RESULTS: Data collection for this trial, funded by the Patient-Centered Outcomes Research Institute, will be completed by December 2017. Results from the trial will be available mid-2018. CONCLUSIONS: This protocol details a patient-centered intervention using nurse health coaching, mHealth technologies, and integration of patient-generated data into the EHR. The aim of the intervention is to enhance self-efficacy and health outcomes by providing participants with a mechanism to track daily activity by offering coaching support to set reasonable and attainable health goals, and by creating a complete feedback loop by bringing patient-generated data into the EHR.

PMID- 29449201 TI - Peer Coaching Through mHealth Targeting Physical Activity in People With Parkinson Disease: Feasibility Study. AB - BACKGROUND: Long-term engagement in exercise and physical activity mitigates the progression of disability and increases quality of life in people with Parkinson disease (PD). Despite this, the vast majority of individuals with PD are sedentary. There is a critical need for a feasible, safe, acceptable, and effective method to assist those with PD to engage in active lifestyles. Peer coaching through mobile health (mHealth) may be a viable approach. OBJECTIVE: The purpose of this study was to develop a PD-specific peer coach training program and a remote peer-mentored walking program using mHealth technology with the goal of increasing physical activity in persons with PD. We set out to examine the feasibility, safety, and acceptability of the programs along with preliminary evidence of individual-level changes in walking activity, self-efficacy, and disability in the peer mentees. METHODS: A peer coach training program and a remote peer-mentored walking program using mHealth was developed and tested in 10 individuals with PD. We matched physically active persons with PD (peer coaches) with sedentary persons with PD (peer mentees), resulting in 5 dyads. Using both Web-based and in-person delivery methods, we trained the peer coaches in basic knowledge of PD, exercise, active listening, and motivational interviewing. Peer coaches and mentees wore FitBit Zip activity trackers and participated in daily walking over 8 weeks. Peer dyads interacted daily via the FitBit friends mobile app and weekly via telephone calls. Feasibility was determined by examining recruitment, participation, and retention rates. Safety was assessed by monitoring adverse events during the study period. Acceptability was assessed via satisfaction surveys. Individual-level changes in physical activity were examined relative to clinically important differences. RESULTS: Four out of the 5 peer pairs used the FitBit activity tracker and friends function without difficulty. A total of 4 of the 5 pairs completed the 8 weekly phone conversations. There were no adverse events over the course of the study. All peer coaches were "satisfied" or "very satisfied" with the training program, and all participants were "satisfied" or "very satisfied" with the peer-mentored walking program. All participants would recommend this program to others with PD. Increases in average steps per day exceeding the clinically important difference occurred in 4 out of the 5 mentees. CONCLUSIONS: Remote peer coaching using mHealth is feasible, safe, and acceptable for persons with PD. Peer coaching using mHealth technology may be a viable method to increase physical activity in individuals with PD. Larger controlled trials are necessary to examine the effectiveness of this approach. PMID- 29449202 TI - A Web-Based Psychoeducational Intervention for Adolescent Depression: Design and Development of MoodHwb. AB - BACKGROUND: Depression is common in adolescence and leads to distress and impairment in individuals, families and carers. Treatment and prevention guidelines highlight the key role of information and evidence-based psychosocial interventions not only for individuals but also for their families and carers. Engaging young people in prevention and early intervention programs is a challenge, and early treatment and prevention of adolescent depression is a major public health concern. There has been growing interest in psychoeducational interventions to provide accurate information about health issues and to enhance and develop self-management skills. However, for adolescents with, or at high risk of depression, there is a lack of engaging Web-based psychoeducation programs that have been developed with user input and in line with research guidelines and targeted at both the individual and their family or carer. There are also few studies published on the process of development of Web-based psychoeducational interventions. OBJECTIVE: The aim of this study was to describe the process underlying the design and development of MoodHwb (HwbHwyliau in Welsh): a Web-based psychoeducation multimedia program for young people with, or at high risk of, depression and their families, carers, friends, and professionals. METHODS: The initial prototype was informed by (1) a systematic review of psychoeducational interventions for adolescent depression; (2) findings from semistructured interviews and focus groups conducted with adolescents (with depressive symptoms or at high risk), parents or carers, and professionals working with young people; and (3) workshops and discussions with a multimedia company and experts (in clinical, research, and multimedia work). Twelve interviews were completed (four each with young people, parents or carers, and professionals) and six focus groups (three with young people, one with parents and carers, one with professionals, and one with academics). RESULTS: Key themes from the interviews and focus groups were: aims of the program, design and content issues, and integration and context of the program. The prototype was designed to be person-centered, multiplatform, engaging, interactive, and bilingual. It included mood-monitoring and goal-setting components and was available as a Web-based program and an app for mobile technologies. CONCLUSIONS: MoodHwb is a Web-based psychoeducational intervention developed for young people with, or at high risk of, depression and their families and carers. It was developed with user input using qualitative methods as well as user-centered design and educational and psychological theory. Further research is needed to evaluate the effectiveness of the program in a randomized controlled trial. If found to be effective, it could be implemented in health, education, youth and social services, and charities, to not only help young people but also families, carers, friends, and professionals involved in their care. PMID- 29449203 TI - Influencing the Conversation About Masculinity and Suicide: Evaluation of the Man Up Multimedia Campaign Using Twitter Data. AB - BACKGROUND: It has been suggested that some dominant aspects of traditional masculinity are contributing to the high suicide rates among Australian men. We developed a three-episode documentary called Man Up, which explores the complex relationship between masculinity and suicide and encourages men to question socially imposed rules about what it means to be a man and asks them to open up, express difficult emotions, and seek help if and when needed. We ran a three phase social media campaign alongside the documentary using 5 channels (Twitter, Facebook, Instagram, YouTube, and Tumblr). OBJECTIVE: This study aimed to examine the extent to which the Man Up Twitter campaign influenced the social media conversation about masculinity and suicide. METHODS: We used Twitter insights data to assess the reach of and engagement with the campaign (using metrics on followers, likes, retweets, and impressions) and to determine the highest and lowest performing tweets in the campaign (using an aggregated performance measure of reactions). We used original content tweets to determine whether the campaign increased the volume of relevant Twitter conversations (aggregating the number of tweets for selected campaign hashtags over time), and we used a subset of these data to gain insight into the main content themes with respect to audience engagement. RESULTS: The campaign generated a strong following that was engaged with the content of the campaign; over its whole duration, the campaign earned approximately 5000 likes and 2500 retweets and gained around 1,022,000 impressions. The highest performing tweets posted by the host included video footage and occurred during the most active period of the campaign (around the screening of the documentary). The volume of conversations in relation to commonly used hashtags (#MANUP, #ABCMANUP, #LISTENUP, and #SPEAKUP) grew in direct relation to the campaign activities, achieving strongest growth during the 3 weeks when the documentary was aired. Strongest engagement was found with content related to help-seeking, masculinity, and expressing emotions. A number of followers tweeted personal stories that revealed overwhelmingly positive perceptions of the content of the documentary and strongly endorsed its messages. CONCLUSIONS: The Man Up Twitter campaign triggered conversations about masculinity and suicide that otherwise may not have happened. For some, this may have been game-changing in terms of shifting attitudes toward expressing emotions and reaching out to others for help. The campaign was particularly effective in disseminating information and promoting conversations in real time, an advantage that it had over more traditional health promotion campaigns. This sort of approach could well be adapted to other areas of mental (and physical) health promotion campaigns to increase their reach and effectiveness. PMID- 29449205 TI - Infographic.

AB - BACKGROUND: The assessment of food consumption data using harmonized methodologies at the European level is fundamental to support the development of public policies. Portugal is one of the countries with the most outdated information on individual food consumption. OBJECTIVE: The objective of this study was to describe the design and methodology of the National Food, Nutrition and Physical Activity Survey, 2015-2016, developed to collect national and regional data on dietary habits, physical activity (PA), and nutritional status, in a representative sample of the Portuguese general population (3 months-84 years). METHODS: Participants were selected by multistage sampling, using the National Heath Registry as the sampling frame. Data collection, during 12 months, was harmonized according to European guidelines (EU-MENU, European Food Safety Authority [EFSA]). Computer-assisted personal interviewing (CAPI) was performed on a specific electronic platform synchronized with nutritional composition data and considering the FoodEx2 classification system. Dietary assessment was performed using 24-hour recalls (two nonconsecutive, 8-15 days apart) or food diaries in the case of children aged <10 years, complemented with a food propensity questionnaire; PA data (International Physical Activity Questionnaire [IPAQ], the Activity Choice Index [ACI], and 4-days PA diaries); sociodemographic data, and other health-related data were also collected. RESULTS: A sample of 6553 individuals completed the first interview, and 5811 participants completed two dietary assessments. The participation rate among eligible individuals was 33.38% (6553/19,635), considering the first interview, and 29.60% (5811/19,635) for the participants with two completed interviews (about 40% in children and adolescents and 20% in elderly individuals). Results of the survey will be disseminated in national and international scientific journals during 2018-2019. CONCLUSIONS: The survey will assist policy planning and management of national and European health programs on the improvement of nutritional status and risk assessment related to food hazards, and the enhancement of PA. The infrastructures and data driven from this Survey are a solid basis to the development of a future national surveillance system on diet, PA, and other health behaviors reproducible over time.

AB - OBJECTIVE: To determine the prevalence of invasive bacterial infections (IBI, pathogenic bacteria in blood or cerebrospinal fluid) in infants less than 90 days old with fever without a source related to the presence or absence of fever on arrival to the emergency department (ED). DESIGN: Prospective registry-based cohort study. SETTING: Paediatric ED of a tertiary teaching hospital. PATIENTS: We included infants less than 90 days old with a history of fever evaluated in the ED from 2003 to 2016. MAIN OUTCOMES AND MEASURES: The prevalence of IBI in patients with a history of fever who were febrile and afebrile on arrival to the ED. RESULTS: We included 2470 infants: 678 afebrile and 1792 febrile when evaluated in the ED. Fifty-nine (2.4%) were diagnosed with an IBI (bacteraemia 46, meningitis 7 and sepsis 6): 16 in the group of afebrile infants with a history of fever (2.4%, 95% CI 1.4 to 3.8 vs 43 in the febrile group, 2.4%, 95% CI 1.8 to 3.2). Of the 16 afebrile infants with a history of fever diagnosed with an IBI, 14 were well appearing. The rate of non-IBI (pathogenic bacteria in urine or stools) was similar in both groups (15.5% and 16.7%). CONCLUSIONS: The prevalence of IBI in infants <=90 days with a history of fever is similar regardless of the presence of fever on the arrival at the ED. The approach to infants with a history of fever who are afebrile in the ED should not differ from that recommended for infants who are febrile in the ED.

AB - Therapeutic induction of blood vessel growth (angiogenesis) in ischemic tissues holds great potential for treatment of myocardial infarction and stroke. Achieving sustained angiogenesis and vascular maturation has, however, been highly challenging. Here, we demonstrate that alginate:collagen hydrogels containing therapeutic, pro-angiogenic FGF-2, and formulated as microspheres, is a promising and clinically relevant vehicle for therapeutic angiogenesis. By titrating the amount of readily dissolvable and degradable collagen with more slowly degradable alginate in the hydrogel mixture, the degradation rates of the biomaterial controlling the release kinetics of embedded pro-angiogenic FGF-2 can be adjusted. Furthermore, we elaborate a microsphere synthesis protocol allowing accurate control over sphere size, also a critical determinant of degradation/release rate. As expected, alginate:collagen microspheres were completely biocompatible and did not cause any adverse reactions when injected in mice. Importantly, the amount of pro-angiogenic FGF-2 released from such microspheres led to robust induction of angiogenesis in zebrafish embryos similar to that achieved by injecting FGF-2-releasing cells. These findings highlight the use of microspheres constructed from alginate:collagen hydrogels as a promising and clinically relevant delivery system for pro-angiogenic therapy. PMID- 29449217 TI - ZFP36L2 is a cell cycle-regulated CCCH protein necessary for DNA lesion-induced S phase arrest. AB - ZFP36L2 promotes the destruction of AU-rich element-containing transcripts, while its regulation and functional significance in cell cycle control are scarcely identified. We show that ZFP36L2 is a cell cycle-regulated CCCH protein, the abundance of which is regulated post-translationally at the respective stages of the cell cycle. Indeed, ZFP36L2 protein was eliminated after release from M phase, and ZYG11B-based E3 ligase plays a role in its polyubiquitination in interphase. Although ZFP36L2 is dispensable for normal cell cycle progression, we found that endogenous ZFP36L2 played a key role in cisplatin-induced S-phase arrest, a process in which the suppression of G1/S cyclins is necessary. The accumulation of ZFP36L2 was stimulated under DNA replication stresses and altered interactions with a subset of RNA-binding proteins. Notably, silencing endogenous ZFP36L2 led to impaired cell viability in the presence of cisplatin-induced DNA lesions. Thus, we propose that ZFP36L2 is a key protein that controls S-phase progression in the case of genome instability.

PMID- 29449219 TI - Interventions to reduce sedentary behaviour in 0-5-year-olds: a systematic review and meta-analysis of randomised controlled trials. AB - AIM OR OBJECTIVE: To evaluate the effectiveness of behavioural interventions that report sedentary behaviour outcomes during early childhood. DESIGN: Systematic review and meta-analysis. DATA SOURCES: Academic Search Complete, CINAHL Complete, Global Health, MEDLINE Complete, PsycINFO, SPORTDiscus with Full Text and EMBASE electronic databases were searched in March 2016. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Inclusion criteria were: (1) published in a peer-reviewed English language journal; (2) sedentary behaviour outcomes reported; (3) randomised controlled trial (RCT) study design; and (4) participants were children with a mean age of <=5.9 years and not yet attending primary/elementary school at postintervention. RESULTS: 31 studies were included in the systematic review and 17 studies in the meta-analysis. The overall mean difference in screen time outcomes between groups was -17.12 (95% CI -28.82 to -5.42) min/day with a significant overall intervention effect (Z=2.87, p=0.004). The overall mean difference in sedentary time between groups was -18.91 (95% CI -33.31 to -4.51) min/day with a significant overall intervention effect (Z=2.57, p=0.01). Subgroup analyses suggest that for screen time, interventions of >=6 months duration and those conducted in a community-based setting are most effective. For sedentary time, interventions targeting physical activity (and reporting changes in sedentary time) are more effective than those directly targeting sedentary time. SUMMARY/CONCLUSIONS: Despite heterogeneity in study methods and results, overall interventions to reduce sedentary behaviour in early childhood show significant reductions, suggesting that this may be an opportune time to intervene.

PMID- 29449224 TI - Natural killer receptor ligand expression on acute myeloid leukemia impacts survival and relapse after chemotherapy. AB - Natural killer (NKs) cells provide rapid responses to viral-infected and malignant cells, including acute myeloid leukemia (AML) blasts. The balance among inhibitory and activating signals, delivered by multiple interactions between ligands on target cells and NK receptors, determines the posture of the NK cell response to either one of target cell elimination or tolerance. The aim of this work was to study the influence of the differential expression of activating and inhibitory NK receptor ligands (NKRLs) by leukemic blasts on clinical outcome in newly diagnosed AML patients. Leukemic cells and clinical data from 66 patients undergoing induction chemotherapy were obtained from the Australasian Leukemia Lymphoma Group tissue bank. Expression of 6 activating (MICA, MICAB, CD155, CD112, ULBP1, and ULBP2/5/6) and 3 inhibitory (HLA class I, PD-L1, and PD-L2) NKRLs was analyzed by flow cytometry. AML blasts displayed heterogeneous expression of NKRLs. MICA, CD112, and ULBP1 were most frequently expressed. ULBP1 expression was significantly associated with improved 2-year overall survival (51.4% vs 11.4%), relapse-free survival (42.5% vs 10.0%), and reduced relapse (44.1% vs 78.6%). We calculated a net score of activating minus inhibitory ligands and demonstrated that the expression of an overall activating NK ligand phenotype was associated with superior 2-year overall survival (59.6% vs 24.4%) and reduced relapse (31.5% vs 68.2%). Our study provides clinical evidence for the role of NK cell-mediated immunoediting against AML, mediated by the expression of NKRLs on blasts, and supports investigation into strategies to enhance NK cell function to improve outcomes in patients with AML.

PMID- 29449241 TI - Simplified guideline for prescribing medical cannabinoids in primary care. AB - OBJECTIVE: To develop a clinical practice guideline for a simplified approach to medical cannabinoid use in primary care; the focus was on primary care application, with a strong emphasis on best available evidence and a promotion of shared, informed decision making. METHODS: The Evidence Review Group performed a detailed systematic review of 4 clinical areas with the best evidence around cannabinoids: pain, nausea and vomiting, spasticity, and adverse events. Nine health professionals (2 generalist family physicians, 2 pain management-focused family physicians, 1 inner-city family physician, 1 neurologist, 1 oncologist, 1 nurse practitioner, and 1 pharmacist) and a patient representative comprised the Prescribing Guideline Committee (PGC), along with 2 nonvoting members (pharmacist project managers). Member selection was based on profession, practice setting, location, and lack of financial conflicts of interest. The guideline process was iterative through content distribution, evidence review, and telephone and online meetings. The PGC directed the Evidence Review Group to address and provide evidence for additional questions as needed. The key recommendations were derived through consensus of the PGC. The guideline was drafted, refined, and distributed to a group of clinicians and patients for feedback, then refined again and finalized by the PGC. RECOMMENDATIONS: Recommendations include limiting medical cannabinoid use in general, but also outline potential restricted use in a small subset of medical conditions for which there is some evidence (neuropathic pain, palliative and end-of-life pain, chemotherapy-induced nausea and vomiting, and spasticity due to multiple sclerosis or spinal cord injury). Other important considerations regarding prescribing are reviewed in detail, and content is offered to support shared, informed decision making. CONCLUSION: This simplified medical cannabinoid prescribing guideline provides practical recommendations for the use of medical cannabinoids in primary care. All recommendations are intended to assist with, not dictate, decision making in conjunction with patients.

AB - OBJECTIVE: To examine the consistency of the ranking of Canadian and US medical graduates who applied to Canadian family medicine (FM) residency programs between 2007 and 2013. DESIGN: Descriptive cross-sectional study. SETTING: Family medicine residency programs in Canada. PARTICIPANTS: All 17 Canadian medical schools allowed access to their anonymized program rank-order lists of students applying to FM residency programs submitted to the first iteration of the Canadian Resident Matching Service match from 2007 to 2013. MAIN OUTCOME MEASURES: The rank position of medical students who applied to more than 1 FM residency program on the rank-order lists submitted by the programs. Anonymized ranking data submitted to the Canadian Resident Matching Service from 2007 to 2013 by all 17 FM residency programs were used. Ranking data of eligible Canadian and US medical graduates were analyzed to assess the within-student and between student variability in rank score. These covariance parameters were then used to calculate the intraclass correlation coefficient (ICC) for all programs. Program descriptions and selection criteria were also reviewed to identify sites with similar profiles for subset ICC analysis. RESULTS: Between 2007 and 2013, the consistency of ranking by all programs was fair at best (ICC = 0.34 to 0.39). The consistency of ranking by larger urban-based sites was weak to fair (ICC = 0.23 to 0.36), and the consistency of ranking by sites focusing on training for rural practice was weak to moderate (ICC = 0.16 to 0.55). CONCLUSION: In most cases, there is a low level of consistency of ranking of students applying for FM training in Canada. This raises concerns regarding fairness, particularly in relation to expectations around equity and distributive justice in selection processes.

AB - OBJECTIVE: To describe recent trends and patterns in methadone maintenance treatment (MMT) practice regionally and over time in the province of Ontario. DESIGN: Population-based descriptive study using health administrative data between September 1, 2011, and December 31, 2014. SETTING: Ontario. PARTICIPANTS: All active MMT-prescribing physicians and patients receiving MMT in the study period. MAIN OUTCOME MEASURES: Characteristics of MMT-prescribing physicians, including age, sex, specialty type, practice region, and practice volume; characteristics of patients receiving MMT, including age, sex, neighbourhood income, and region of residence. RESULTS: Between September 1, 2011, and December 31, 2014, the number of MMT-prescribing physicians and patients who received MMT increased by 26% and 42%, respectively. In 2014, there was a total of 312 MMT prescribing physicians and 49 703 patients receiving MMT. In 2014 and on a per capita basis, patients receiving MMT were more prevalent in rural regions; and within rural regions, there were disproportionately large numbers of young female MMT patients residing in low-income neighbourhoods. CONCLUSION: The number of physicians prescribing MMT and patients receiving MMT has increased substantially between 2011 and 2014, with the largest per capita distribution occurring in rural regions and involving young adults. While availability of and access to MMT has improved considerably from before 2000 to levels of high use, these developments are likely influenced by recent trends in the proliferation of prescription opioid misuse across general populations. PMID- 29449262 TI - Systematic review of systematic reviews for medical cannabinoids: Pain, nausea and vomiting, spasticity, and harms. AB - OBJECTIVE: To determine the effects of medical cannabinoids on pain, spasticity, and nausea and vomiting, and to identify adverse events. DATA SOURCES: MEDLINE, the Cochrane Database, and the references of included studies were searched. STUDY SELECTION: Systematic reviews with 2 or more randomized controlled trials (RCTs) that focused on medical cannabinoids for pain, spasticity, or nausea and vomiting were included. For adverse events, any meta-analysis for the conditions listed or of adverse events of cannabinoids was included. SYNTHESIS: From 1085 articles, 31 relevant systematic reviews were identified including 23 for pain, 5 for spasticity, 6 for nausea and vomiting, and 12 for adverse events. Meta analysis of 15 RCTs found more patients taking cannabinoids attained at least a 30% pain reduction: risk ratio (RR) of 1.37 (95% CI 1.14 to 1.64), number needed to treat (NNT) of 11. Sensitivity analysis found study size and duration affected findings (subgroup differences, P <= .03), with larger and longer RCTs finding no benefit. Meta-analysis of 4 RCTs found a positive global impression of change in spasticity (RR = 1.45, 95% CI 1.08 to 1.95, NNT = 7). Other results were not consistently statistically significant, but when positive, a 30% or more improvement in spasticity had an NNT of 10. Meta-analysis of 7 RCTs for control of nausea and vomiting after chemotherapy found an RR of 3.60 (95% CI 2.55 to 5.09) with an NNT of 3. Adverse effects caused more patients to stop treatment (number needed to harm [NNH] of 8 to 22). Individual adverse events were very common, including dizziness (NNH = 5), sedation (NNH = 5), confusion (NNH = 15), and dissociation (NNH = 20). "Feeling high" was reported in 35% to 70% of users. The GRADE (Grading of Recommendations Assessment, Development and Evaluation) evaluation reduced evidence ratings of benefit to low or very low. CONCLUSION: There is reasonable evidence that cannabinoids improve nausea and vomiting after chemotherapy. They might improve spasticity (primarily in multiple sclerosis). There is some uncertainty about whether cannabinoids improve pain, but if they do, it is neuropathic pain and the benefit is likely small. Adverse effects are very common, meaning benefits would need to be considerable to warrant trials of therapy. PMID- 29449265 TI - Patients find it easy to select data they don't want to share. PMID- 29449266 TI - Fungal liver abscess in an immunocompetent patient who underwent repeated ERCPs and subtotal cholecystectomy. AB - We report a case of a previously healthy female patient who initially presented with fever, jaundice and right upper quadrant pain three days after dilatation and stenting of a stricture of the common bile duct (CBD). During an earlier admission, the patient had undergone endoscopic retrograde cholangiopancreatography (ERCP) having presented with fevers and biliary dilatation on ultrasound. The ERCP features were more consistent with Mirizzi's Syndrome. The patient subsequently underwent subtotal cholecystectomy and later developed a CBD stricture, requiring repeat ERCP and stent insertion. At presentation, she had moderately deranged liver function tests and significantly elevated inflammatory markers and was found on cross-sectional imaging to have developed a liver abscess. Aspiration of the lesion cultured Candida albicans She was treated with intravenous antifungals, broad-spectrum antibiotics and further aspiration of abscess, which contributed towards her successful recovery. Fungal liver abscess should be suspected in immunocompetent patients who undergo ERCP and or cholecystectomy. PMID- 29449268 TI - Seven days in medicine: 7-13 February 2018. PMID- 29449267 TI - Single-Cell Transcriptome Analyses Reveal Endothelial Cell Heterogeneity in Tumors and Changes following Antiangiogenic Treatment. AB - Angiogenesis involves dynamic interactions between specialized endothelial tip and stalk cells that are believed to be regulated in part by VEGF and Dll4-Notch signaling. However, our understanding of this process is hampered by limited knowledge of the heterogeneity of endothelial cells and the role of different signaling pathways in specifying endothelial phenotypes. Here, we characterized by single-cell transcriptomics the heterogeneity of mouse endothelial cells and other stromal cells during active angiogenesis in xenograft tumors as well as from adult normal heart, following pharmacologic inhibition of VEGF and Dll4 Notch signaling. We classified tumor endothelial cells into three subpopulations that appeared to correspond with tip-like, transition, and stalk-like cells. Previously identified markers for tip and stalk cells were confirmed and several novel ones discovered. Blockade of VEGF rapidly inhibited cell-cycle genes and strongly reduced the proportion of endothelial tip cells in tumors. In contrast, blockade of Dll4 promoted endothelial proliferation as well as tip cell markers; blockade of both pathways inhibited endothelial proliferation but preserved some tip cells. We also phenotypically classified other tumor stromal cells and found that tumor-associated fibroblasts responded to antiangiogenic drug treatments by upregulating hypoxia-associated genes and producing secreted factors involved in angiogenesis. Overall, our findings better define the heterogeneity of tumor endothelial and other stromal cells and reveal the roles of VEGF and Dll4-Notch in specifying tumor endothelial phenotype, highlighting the response of stromal cells to antiangiogenic therapies.Significance: These findings provide a framework for defining subpopulations of endothelial cells and tumor-associated fibroblasts and their rapid changes in gene expression following antiangiogenic treatment.

PMID- 29449269 TI - Awhina Revolution: A Bayesian Analysis of Undergraduate and Postgraduate Completion Rates from a Program for Maori and Pacific Success in STEM Disciplines. AB - Maori and Pacific students generally do not attain the same levels of tertiary success as New Zealanders of European descent, particularly in science, technology, engineering, and mathematics (STEM) subjects. Te Ropu Awhina (Awhina), an equity initiative at Victoria University of Wellington in New Zealand between 1999 and 2015, aimed to produce Maori and Pacific professionals in STEM disciplines who contribute to Maori and Pacific community development and leadership. A hierarchical Bayesian approach was used to estimate posterior standardized completion rates for 3-year undergraduate and 2-year postgraduate degrees undertaken by non-Maori-Pacific and Maori-Pacific students. Results were consistent with an Awhina effect, that is, Awhina's positive influence on (combined) Maori and Pacific success. PMID- 29449270 TI - Internship Experiences Contribute to Confident Career Decision Making for Doctoral Students in the Life Sciences. AB - The Graduate Student Internships for Career Exploration (GSICE) program at the University of California, San Francisco (UCSF), offers structured training and hands-on experience through internships for a broad range of PhD-level careers. The GSICE program model was successfully replicated at the University of California, Davis (UC Davis). Here, we present outcome data for a total of 217 PhD students participating in the UCSF and UC Davis programs from 2010 to 2015 and 2014 to 2015, respectively. The internship programs at the two sites demonstrated comparable participation, internship completion rates, and overall outcomes. Using survey, focus group, and individual interview data, we find that the programs provide students with career development skills, while increasing students' confidence in career exploration and decision making. Internships, in particular, were perceived by students to increase their ability to discern a career area of choice and to increase confidence in pursuing that career. We present data showing that program participation does not change median time to degree and may help some trainees avoid "default postdocs." Our findings suggest important strategies for institutions developing internship programs for PhD students, namely: including a structured training component, allowing postgraduation internships, and providing a central organization point for internship programs. PMID- 29449271 TI - Targeted Therapies for Targeted Populations: Anti-EGFR Treatment for EGFR Amplified Gastroesophageal Adenocarcinoma. AB - Previous anti-EGFR trials in unselected patients with gastroesophageal adenocarcinoma (GEA) were resoundingly negative. We identified EGFR amplification in 5% (19/363) of patients at the University of Chicago, including 6% (8/140) who were prospectively screened with intention-to-treat using anti-EGFR therapy. Seven patients received >=1 dose of treatment: three first-line FOLFOX plus ABT 806, one second-line FOLFIRI plus cetuximab, and three third/fourth-line cetuximab alone. Treatment achieved objective response in 58% (4/7) and disease control in 100% (7/7) with a median progression-free survival of 10 months. Pretreatment and posttreatment tumor next-generation sequencing (NGS), serial plasma circulating tumor DNA (ctDNA) NGS, and tumor IHC/FISH for EGFR revealed preexisting and/or acquired genomic events, including EGFR-negative clones, PTEN deletion, KRAS amplification/mutation, NRAS, MYC, and HER2 amplification, and GNAS mutations serving as mechanisms of resistance. Two evaluable patients demonstrated interval increase of CD3+ infiltrate, including one who demonstrated increased NKp46+, and PD-L1 IHC expression from baseline, suggesting an immune therapeutic mechanism of action. EGFR amplification predicted benefit from anti EGFR therapy, albeit until various resistance mechanisms emerged.Significance: This paper highlights the role of EGFR inhibitors in EGFR-amplified GEA-despite negative results in prior unselected phase III trials. Using serial ctDNA and tissue NGS, we identified mechanisms of primary and acquired resistance in all patients, as well as potential contribution of antibody-dependent cell-mediated cytotoxicity to their clinical benefit.

PMID- 29449272 TI - Differential Clinical Outcomes Between Angiographic Complete Versus Incomplete Coronary Revascularization, According to the Presence of Chronic Kidney Disease in the Drug-Eluting Stent Era. AB - BACKGROUND: There are limited data regarding the prognostic impact of angiographic complete revascularization (CR) in patients with chronic kidney disease (CKD). We sought to investigate the differential prognostic impact of angiographic CR over incomplete revascularization (IR), according to the presence of CKD in the drug-eluting stent era. METHODS AND RESULTS: Between 2003 and 2011 at Samsung Medical Center, consecutive patients with multivessel disease were stratified by the presence of CKD (estimated glomerular filtration rate <60 mL/min per 1.73 m2) and classified according to angiographic CR (residual SYNTAX score=0) or IR. Clinical outcomes were compared between angiographic CR and IR, stratified by the presence of CKD. Primary outcome was patient-oriented composite outcomes (POCO, a composite of all-cause death, myocardial infarction, any revascularization) at 3 years. Inverse probability weighting was performed between the CR and IR groups. A total of 3224 patients were eligible for analysis: 2295 without CKD; 929 with CKD. Among non-CKD patients, angiographic CR showed a significantly lower risk of POCO than IR (17.2% versus 21.7%, adjusted hazard ratio 0.76, 95% confidence interval, 0.62-0.95, P=0.014), mainly driven by a significantly lower risk of any revascularization. Among CKD patients, however, angiographic CR was associated with a significantly higher risk of POCO than IR (37.7% versus 28.4%, adjusted hazard ratio 1.42, 95% confidence interval, 1.08% 1.85%, P=0.011), mainly driven by a significantly higher risk of nonfatal target vessel myocardial infarction. CONCLUSIONS: Angiographic CR was associated with reduced risk of POCO than IR in patients without CKD; however, it was associated with a significantly higher risk of POCO and nonfatal myocardial infarction in CKD patients. PMID- 29449273 TI - Novel Patient-Centered Approach to Facilitate Same-Day Discharge in Patients Undergoing Elective Percutaneous Coronary Intervention. AB - BACKGROUND: Same-day discharge (SDD) after elective percutaneous coronary intervention is safe, less costly, and preferred by patients, but it is usually performed in low-risk patients, if at all. To increase the appropriate use of SDD in more complex patients, we implemented a "patient-centered" protocol based on risk of complications at Barnes-Jewish Hospital. METHODS AND RESULTS: Our objectives were as follows: (1) to evaluate time trends in SDD; (2) to compare (a) mortality, bleeding, and acute kidney injury, (b) patient satisfaction, and (c) hospital costs by SDD versus no SDD (NSDD); and (3) to compare SDD eligibility by our patient-centered approach versus Society for Cardiovascular Angiography and Interventions guidelines. Our patient-centered approach was based on prospectively identifying personalized bleeding, mortality, and acute kidney injury risks, with a personalized safe contrast limit and mitigating those risks. We analyzed Barnes-Jewish Hospital's National Cardiovascular Data Registry CathPCI Registry data from July 1, 2009 to September 30, 2015 (N=1752). SDD increased rapidly from 0% to 77% (P<0.001), independent of radial access. Although SDD patients were comparable to NSDD patients, SDD was not associated with adverse outcomes (0% mortality, 0% bleeds, and 0.4% acute kidney injury). Patient satisfaction was high with SDD. Propensity score-adjusted costs were $7331 lower/SDD patient (P<0.001), saving an estimated $1.8 million annually. Only 16 patients (6.95%) met the eligibility for SDD by Society for Cardiovascular Angiography and Interventions guidelines, implying our patient centered approach markedly increased SDD eligibility. CONCLUSIONS: With a patient centered approach, SDD rapidly increased and was safe in 75% of patients undergoing elective percutaneous coronary intervention, despite patient complexity. Patient satisfaction was high, and hospital costs were lower. Patient centered decision making to facilitate SDD is an important opportunity to improve the value of percutaneous coronary intervention. PMID- 29449274 TI - Clinical Relevance of Functionally Insignificant Moderate Coronary Artery Stenosis Assessed by 3-Vessel Fractional Flow Reserve Measurement. AB - BACKGROUND: Understanding of the risk conferred by functionally insignificant lesions in multiple coronary vessels is limited. We investigated the prognostic implications of coronary artery disease (CAD) based on 3-vessel fractional flow reserve (FFR). METHODS AND RESULTS: A total of 1,136 patients underwent FFR measurement in the 3 major epicardial arteries. We defined vessels with "Moderate CAD" as vessels with FFR, 0.81 to 0.87. Patients were classified into Group 1: No apparent CAD (FFR>0.87 in all 3-vessels); Group 2: Single-vessel moderate CAD; Group 3: Multivessel moderate CAD; and Group 4: Functionally significant CAD (FFR<=0.80) in any vessel. The primary end point was 2-year major adverse cardiac events, a composite of cardiac death, myocardial infarction, and ischemia-driven revascularization. Forty-three percent of patients had moderate CAD (Group 2: 403/1136, 35.5%; Group 3: 84/1136, 7.4%). The 2-year risk of major adverse cardiac events was not significantly different between patients with single vessel moderate CAD and no apparent CAD (2.6 versus 2.6%; HR, 1.1; 95% confidence interval, 0.4%-2.8%; P=0.89). However, patients with multivessel moderate CAD were at significantly higher risk than Group 1 (7.4 versus 2.6%; hazard ratio, 3.3; 95% confidence interval, 1.1%-9.8%; P=0.03). The risk of major adverse cardiac events in patients with multivessel moderate CAD was comparable to that of patients with functionally significant CAD (hazard ratio, 1.2; 95% confidence interval, 0.5%-3.0%; P=0.67). In a multivariable regression model, multivessel moderate CAD was an independent predictor of greater risk of 2-year major adverse cardiac events. CONCLUSIONS: Global physiologic assessment with FFR measurement of 3 vessels can identify multivessel moderate CAD. The prognostic implication of multivessel moderate CAD appears comparable to that of functionally significant CAD. CLINICAL TRIAL REGISTRATION: URL: http://www.clinicaltrials.gov. Unique identifier: NCT01621438. PMID- 29449275 TI - Circulating tumor DNA reveals genetics, clonal evolution, and residual disease in classical Hodgkin lymphoma. AB - The rarity of neoplastic cells in the biopsy imposes major technical hurdles that have so far limited genomic studies in classical Hodgkin lymphoma (cHL). By using a highly sensitive and robust deep next-generation sequencing approach for circulating tumor DNA (ctDNA), we aimed to identify the genetics of cHL in different clinical phases, as well as its modifications on treatment. The analysis was based on specimens collected from 80 newly diagnosed and 32 refractory patients with cHL, including longitudinal samples collected under ABVD (adriamycin, bleomycin, vinblastine, dacarbazine) chemotherapy and longitudinal samples from relapsing patients treated with chemotherapy and immunotherapy. ctDNA mirrored Hodgkin and Reed-Sternberg cell genetics, thus establishing ctDNA as an easily accessible source of tumor DNA for cHL genotyping. By identifying STAT6 as the most frequently mutated gene in ~40% of cases, we refined the current knowledge of cHL genetics. Longitudinal ctDNA profiling identified treatment-dependent patterns of clonal evolution in patients relapsing after chemotherapy and patients maintained in partial remission under immunotherapy. By measuring ctDNA changes during therapy, we propose ctDNA as a radiation-free tool to track residual disease that may integrate positron emission tomography imaging for the early identification of chemorefractory patients with cHL. Collectively, our results provide the proof of concept that ctDNA may serve as a novel precision medicine biomarker in cHL. PMID- 29449277 TI - Modeling Early Postnatal Brain Growth and Development with CT: Changes in the Brain Radiodensity Histogram from Birth to 2 Years. AB - BACKGROUND AND PURPOSE: The majority of brain growth and development occur in the first 2 years of life. This study investigated these changes by analysis of the brain radiodensity histogram of head CT scans from the clinical population, 0-2 years of age. MATERIALS AND METHODS: One hundred twenty consecutive head CTs with normal findings meeting the inclusion criteria from children from birth to 2 years were retrospectively identified from 3 different CT scan platforms. Histogram analysis was performed on brain-extracted images, and histogram mean, mode, full width at half maximum, skewness, kurtosis, and SD were correlated with subject age. The effects of scan platform were investigated. Normative curves were fitted by polynomial regression analysis. RESULTS: Average total brain volume was 360 cm3 at birth, 948 cm3 at 1 year, and 1072 cm3 at 2 years. Total brain tissue density showed an 11% increase in mean density at 1 year and 19% at 2 years. Brain radiodensity histogram skewness was positive at birth, declining logarithmically in the first 200 days of life. The histogram kurtosis also decreased in the first 200 days to approach a normal distribution. Direct segmentation of CT images showed that changes in brain radiodensity histogram skewness correlated with, and can be explained by, a relative increase in gray matter volume and an increase in gray and white matter tissue density that occurs during this period of brain maturation. CONCLUSIONS: Normative metrics of the brain radiodensity histogram derived from routine clinical head CT images can be used to develop a model of normal brain development. PMID- 29449276 TI - Immune evasion via PD-1/PD-L1 on NK cells and monocyte/macrophages is more prominent in Hodgkin lymphoma than DLBCL. AB - Much focus has been on the interaction of programmed cell death ligand 1 (PD-L1) on malignant B cells with programmed cell death 1 (PD-1) on effector T cells in inhibiting antilymphoma immunity. We sought to establish the contribution of natural killer (NK) cells and inhibitory CD163+ monocytes/macrophages in Hodgkin lymphoma (cHL) and diffuse large B-cell lymphoma (DLBCL). Levels of PD-1 on NK cells were elevated in cHL relative to DLBCL. Notably, CD3-CD56hiCD16-ve NK cells had substantially higher PD-1 expression relative to CD3-CD56dimCD16+ cells and were expanded in blood and tissue, more marked in patients with cHL than patients with DLBCL. There was also a raised population of PD-L1-expressing CD163+ monocytes that was more marked in patients with cHL compared with patients with DLBCL. The phenotype of NK cells and monocytes reverted back to normal once therapy (ABVD [doxorubicin 25 mg/m2, bleomycin 10 000 IU/m2, vinblastine 6 mg/m2, dacarbazine 375 mg/m2, all given days 1 and 15, repeated every 28 days] or R-CHOP [rituximab 375 mg/m2, cyclophosphamide 750 mg/m2 IV, doxorubicin 50 mg/m2 IV, vincristine 1.4 mg/m2 (2 mg maximum) IV, prednisone 100 mg/day by mouth days 1-5, pegfilgrastim 6 mg subcutaneously day 4, on a 14-day cycle]) had commenced. Tumor associated macrophages (TAMs) expressed high levels of PD-L1/PD-L2 within diseased lymph nodes. Consistent with this, CD163/PD-L1/PD-L2 gene expression was also elevated in cHL relative to DLBCL tissues. An in vitro functional model of TAM-like monocytes suppressed activation of PD-1hi NK cells, which was reversed by PD-1 blockade. In line with these findings, depletion of circulating monocytes from the blood of pretherapy patients with cHL and patients with DLBCL enhanced CD3-CD56hiCD16-ve NK-cell activation. We describe a hitherto unrecognized immune evasion strategy mediated via skewing toward an exhausted PD-1-enriched CD3 CD56hiCD16-ve NK-cell phenotype. In addition to direct inhibition of NK cells by the malignant B cell, suppression of NK cells can occur indirectly by PD-L1/PD-L2 expressing TAMs. The mechanism is more prominent in cHL than DLBCL, which may contribute to the clinical sensitivity of cHL to PD-1 blockade. PMID- 29449279 TI - MRI with DWI for the Detection of Posttreatment Head and Neck Squamous Cell Carcinoma: Why Morphologic MRI Criteria Matter. AB - BACKGROUND AND PURPOSE: Although diffusion-weighted imaging combined with morphologic MRI (DWIMRI) is used to detect posttreatment recurrent and second primary head and neck squamous cell carcinoma, the diagnostic criteria used so far have not been clarified. We hypothesized that precise MRI criteria based on signal intensity patterns on T2 and contrast-enhanced T1 complement DWI and therefore improve the diagnostic performance of DWIMRI. MATERIALS AND METHODS: We analyzed 1.5T MRI examinations of 100 consecutive patients treated with radiation therapy with or without additional surgery for head and neck squamous cell carcinoma. MRI examinations included morphologic sequences and DWI (b=0 and b=1000 s/mm2). Histology and follow-up served as the standard of reference. Two experienced readers, blinded to clinical/histologic/follow-up data, evaluated images according to clearly defined criteria for the diagnosis of recurrent head and neck squamous cell carcinoma/second primary head and neck squamous cell carcinoma occurring after treatment, post-radiation therapy inflammatory edema, and late fibrosis. DWI analysis included qualitative (visual) and quantitative evaluation with an ADC threshold. RESULTS: Recurrent head and neck squamous cell carcinoma/second primary head and neck squamous cell carcinoma occurring after treatment was present in 36 patients, whereas 64 patients had post-radiation therapy lesions only. The Cohen kappa for differentiating tumor from post radiation therapy lesions with MRI and qualitative DWIMRI was 0.822 and 0.881, respectively. Mean ADCmean in recurrent head and neck squamous cell carcinoma/second primary head and neck squamous cell carcinoma occurring after treatment (1.097 +/- 0.295 * 10-3 mm2/s) was significantly lower (P < .05) than in post-radiation therapy inflammatory edema (1.754 +/- 0.343 * 10-3 mm2/s); however, it was similar to that in late fibrosis (0.987 +/- 0.264 * 10-3 mm2/s, P > .05). Although ADCs were similar in tumors and late fibrosis, morphologic MRI criteria facilitated distinction between the 2 conditions. The sensitivity, specificity, positive and negative predictive values, and positive and negative likelihood ratios (95% CI) of DWIMRI with ADCmean < 1.22 * 10-3 mm2/s and precise MRI criteria were 92.1% (83.5-100.0), 95.4% (90.3-100.0), 92.1% (83.5-100.0), 95.4% (90.2-100.0), 19.9 (6.58-60.5), and 0.08 (0.03-0.24), respectively, indicating a good diagnostic performance to rule in and rule out disease. CONCLUSIONS: Adding precise morphologic MRI criteria to quantitative DWI enables reproducible and accurate detection of recurrent head and neck squamous cell carcinoma/second primary head and neck squamous cell carcinoma occurring after treatment. PMID- 29449278 TI - 7T Brain MRS in HIV Infection: Correlation with Cognitive Impairment and Performance on Neuropsychological Tests. AB - BACKGROUND AND PURPOSE: Validated neuroimaging markers of HIV-associated neurocognitive disorder in patients on antiretroviral therapy are urgently needed for clinical trials. The purpose of this study was to explore the relationship between cognitive impairment and brain metabolism in older subjects with HIV infection. It was hypothesized that MR spectroscopy measurements related to neuronal health and function (particularly N-acetylaspartate and glutamate) would be lower in HIV-positive subjects with worse cognitive performance. MATERIALS AND METHODS: Forty-five HIV-positive patients (mean age, 58.9 +/- 5.3 years; 33 men) underwent detailed neuropsychological testing and brain MR spectroscopy at 7T. Twenty-four subjects were classified as having asymptomatic cognitive impairment, and 21 were classified as having symptomatic cognitive impairment. Single-voxel proton MR spectra were acquired from 5 brain regions and quantified using LCModel software. Brain metabolites and neuropsychological test results were compared using nonparametric statistics and Pearson correlation coefficients. RESULTS: Differences in brain metabolites were found between symptomatic and asymptomatic subjects, with the main findings being lower measures of N-acetylaspartate in the frontal white matter, posterior cingulate cortex, and precuneus. In the precuneus, glutamate was also lower in the symptomatic group. In the frontal white matter, precuneus, and posterior cingulate cortex, NAA and glutamate measurements showed significant positive correlation with better performance on neuropsychological tests. CONCLUSIONS: Compared with asymptomatic subjects, symptomatic HIV-positive subjects had lower levels of NAA and glutamate, most notably in the frontal white matter, which also correlated with performance on neuropsychological tests. High-field MR spectroscopy offers insight into the pathophysiology associated with cognitive impairment in HIV and may be useful as a quantitative outcome measure in future treatment trials. PMID- 29449280 TI - Prediction of the Multisegment Clot Sign on Dynamic CT Angiography of Cardioembolic Stroke. AB - BACKGROUND AND PURPOSE: The multisegment clot sign has been observed at the site of large-artery occlusion in patients with acute ischemic stroke. This study aimed to assess its occurrence rate and relationship with stroke etiologies in patients with acute intracranial large-artery occlusion. MATERIALS AND METHODS: We included consecutive patients with acute ischemic stroke who had acute intracranial large-artery occlusion and underwent perfusion CT within 8 hours after stroke onset. The multisegment clot sign was assessed on dynamic CT angiography derived from perfusion CT. The stroke etiologies were defined by the international Trial of Org 10172 in Acute Stroke Treatment criteria. Poisson regression analyses and diagnostic testing were used to investigate the relationship between the multisegment clot sign and stroke etiologies. RESULTS: Finally, 194 patients with intracranial large-artery occlusion were enrolled. According to the Trial of Org 10172 in Acute Stroke Treatment criteria, 110 (56.7%) patients were diagnosed with cardioembolism; 43 (22.2%), with large artery atherosclerosis; and 41 (21.1%), with undetermined etiology. The multisegment clot sign was found in 74 (38%) patients. Poisson regression analysis showed that the presence of the multisegment clot sign was significantly higher in patients with cardioembolism than in those with large-artery atherosclerosis (52.7% versus 9.3%; prevalence ratio, 1.53; 95% confidence interval, 1.03-2.90; P = .037). For determined etiologies, the sensitivity, specificity, and positive and negative predictive values of the multisegment clot sign for predicting cardioembolism were 52.7%, 90.7%, 93.5%, and 42.9%, respectively. CONCLUSIONS: The presence of the multisegment clot sign on dynamic CTA specifically indicates intracranial large-artery occlusion caused by an embolism from a cardiac source, which may be useful for acute management and secondary prevention of stroke. PMID- 29449281 TI - MRI Features of Aquaporin-4 Antibody-Positive Longitudinally Extensive Transverse Myelitis: Insights into the Diagnosis of Neuromyelitis Optica Spectrum Disorders. AB - BACKGROUND AND PURPOSE: Longitudinally extensive transverse myelitis is a well documented spinal manifestation of neuromyelitis optica spectrum disorders, however, other forms of nontumorous myelopathy can also manifest as longitudinally extensive transverse myelitis. Our aim was to evaluate the MR imaging features of aquaporin-4 antibody-positive longitudinally extensive transverse myelitis, which is strongly associated with neuromyelitis optica spectrum disorders. MATERIALS AND METHODS: We evaluated cervicomedullary junction involvement, cord expansion ratios, bright spotty lesions, the number of involved segments, skipped lesions, enhancement patterns, and axial distribution patterns using spinal MR imaging of 41 patients with longitudinally extensive transverse myelitis who underwent aquaporin-4 antibody testing. Univariate logistic regression analysis was performed to identify factors associated with aquaporin-4 antibody seropositivity, which were then used to develop a scoring system for diagnosing aquaporin-4 antibody-positive longitudinally extensive transverse myelitis. Interrater reliability for cord expansion ratio measurement and bright spotty lesions was determined using intraclass correlation coefficients and kappa values, respectively. RESULTS: Fifteen patients with longitudinally extensive transverse myelitis were aquaporin-4 antibody-positive. Sex (female), cervicomedullary junction involvement, a cord expansion ratio of >1.4, and bright spotty lesions were significantly associated with aquaporin-4 antibody seropositivity. The sensitivity and specificity of the scoring system were 73.3% and 96.2%, respectively. The interclass correlation value for the cord expansion ratio was 0.78, and the kappa value for bright spotty lesions was 0.61. CONCLUSIONS: Our scoring system, based on cervicomedullary junction involvement, higher cord expansion ratio, bright spotty lesions, and female sex, can facilitate the timely diagnosis of neuromyelitis optica spectrum disorders. PMID- 29449283 TI - Clinical Validation of a Predictive Model for the Presence of Cervical Lymph Node Metastasis in Papillary Thyroid Cancer. AB - BACKGROUND AND PURPOSE: Ultrasound is a standard technique to detect lymph node metastasis in papillary thyroid cancer. Cystic changes and microcalcifications are the most specific features of metastasis, but with low sensitivity. This prospective study compared the diagnostic accuracy of a predictive model for sonographic evaluation of lymph nodes relative to the radiologist's standard assessment in detecting papillary thyroid cancer metastasis in patients after thyroidectomy. MATERIALS AND METHODS: Cervical lymph node sonographic images were reported by a radiologist (R method) per standard practice. The same images were independently evaluated by another radiologist using a sonographic predictive model (M method). A test was considered positive for metastasis if the R or M method suggested lymph node biopsy. The result of lymph node biopsy or surgical pathology was used as the reference standard. We estimated relative true-positive fraction and relative false-positive fraction using log-linear models for correlated binary data for the M method compared with the R method. RESULTS: A total of 237 lymph nodes in 103 patients were evaluated. Our analysis of relative true-positive fraction and relative false-positive fraction included 54 nodes with pathologic results in which at least 1 method (R or M) was positive. The M method had a higher relative true-positive fraction of 1.46 (95% CI, 1.12-1.91; P = .006) and a lower relative false-positive fraction of 0.58 (95% CI, 0.36-0.92; P = .02) compared with the R method. CONCLUSIONS: The sonographic predictive model outperformed the standard assessment to detect lymph node metastasis in patients with papillary thyroid cancer and may reduce unnecessary biopsies.

AB - BACKGROUND AND PURPOSE: The ROI-dose-reduced intervention technique represents an extension of ROI fluoroscopy combining x-ray entrance skin dose reduction with spatially different recursive temporal filtering to reduce excessive image noise in the dose-reduced periphery in real-time. The aim of our study was to compare the image quality of simulated neurointerventions with regular and reduced radiation doses using a standard flat panel detector system. MATERIALS AND METHODS: Ten 3D-printed intracranial aneurysm models were generated on the basis of a single patient vasculature derived from intracranial DSA and CTA. The incident dose to each model was reduced using a 0.7-mm-thick copper attenuator with a circular ROI hole (10-mm diameter) in the middle mounted inside the Infinix C-arm. Each model was treated twice with a primary coiling intervention using ROI-dose-reduced intervention and regular-dose intervention protocols. Eighty images acquired at various intervention stages were shown twice to 2 neurointerventionalists who independently scored imaging qualities (visibility of aneurysm-parent vessel morphology, associated vessels, and/or devices used). Dose reduction measurements were performed using an ionization chamber. RESULTS: A total integral dose reduction of 62% per frame was achieved. The mean scores for regular-dose intervention and ROI dose-reduced intervention images did not differ significantly, suggesting similar image quality. Overall intrarater agreement for all scored criteria was substantial (Kendall tau = 0.62887; P < .001). Overall interrater agreement for all criteria was fair (kappa = 0.2816; 95% CI, 0.2060 0.3571). CONCLUSIONS: Substantial dose reduction (62%) with a live peripheral image was achieved without compromising feature visibility during neuroendovascular interventions.

PMID- 29449287 TI - Global Influenza Hospital-based Surveillance Network (GIHSN): results of surveillance of influenza and other respiratory viruses in hospitalised patients in Brazil, 2015. AB - BACKGROUND: Influenza-like illness occurs annually worldwide, with peak timing and severity varying seasonally, resulting in significant annual mortality. OBJECTIVES: There were three objectives: (1) to describe the epidemiological and clinical features of hospitalised patients with severe acute respiratory infection caused by influenza and other respiratory viruses (ORVs); (2) to report the influenza seasonality in the region and (3) to correlate findings of influenza circulation and immunisation time in Brazil. PATIENTS/METHODS: This study took place in three Brazilian hospitals located in cities with different climatic conditions (Curitiba (south), Rio de Janeiro (south-east) and Fortaleza (north-east)). Patients presenting with an acute process with indication for admission consisting of a predefined set of conditions potentially associated with recent influenza infection were enrolled. RESULTS: We screened 1666 patients, with 595 meeting the inclusion criteria. Influenza viruses and ORVs were detected in 6.5% and 59% of patients, respectively. Influenza-positive cases fell into the severe spectrum as compared with those with ORVs (30% vs 11%), but without any difference in mortality rates. Epidemiological results revealed variations in the peak time of influenza infections between north-east (Fortaleza) and south (Curitiba) Brazil, basically following the rain period of each region. In north-east Brazil, viral circulation was prevalent in the first 4 months of the year, indicating that the vaccination campaign occurred in a postseasonal period, possibly explaining the low effectiveness. CONCLUSIONS: The active-surveillance model is a valuable tool for investigating respiratory virus impact on hospitalised patients, with influenza-infection monitoring enabling implementation of adequate preventive measures.

AB - OBJECTIVES: To investigate differences in ulcer healing time and waiting time between video consultation and inperson assessment for patients with hard-to-heal ulcers. SETTING: Patients treated at Blekinge Wound Healing Centre, a primary care centre covering the whole of Blekinge county (150 000 inhabitants), were compared with patients registered and treated according to the Registry of Ulcer Treatment, a Swedish national web-based quality registry. PARTICIPANTS: In the study for analysing ulcer healing time, the study group consisted of 100 patients diagnosed through video consultation between October 2014 and September 2016. The control group for analysing healing time consisted of 1888 patients diagnosed through inperson assessment during the same period. In the study for analysing waiting time, the same study group (n=100) was compared with 100 patients diagnosed through inperson assessment. PRIMARY AND SECONDARY OUTCOME MEASURES: Differences in ulcer healing time were analysed using the log-rank test. Differences in waiting time were analysed using the Mann-Whitney U test. RESULTS: Median healing time was 59 days (95% CI 40 to 78) in the study group and 82 days (95% CI 75 to 89) in the control group (P<0.001). Median waiting time was 25 days (range: 1-83 days) in the study group and 32 days (range: 3-294 days) for patients diagnosed through inperson assessment (P=0.017). There were no significant differences between the study group and the control group regarding age, gender or ulcer size. CONCLUSIONS: Healing time and waiting time were significantly shorter for patients diagnosed through video consultation compared with those diagnosed through inperson assessment.

A population-based birth cohort study. AB - INTRODUCTION: Maternity Hospital Episode Statistics (HES) data for 2005-2014 were linked to birth registration and birth notification data (previously known as NHS Numbers for Babies or NN4B) to bring together some key demographic and clinical data items not otherwise available at a national level. The linkage algorithm that was previously used to link 2005-2007 data was revised to improve the linkage rate and reduce the number of duplicate HES records. METHODS: Birth registration and notification linked records from the Office for National Statistics ('ONS birth records') were further linked to Maternity HES delivery and birth records using the NHS Number and other direct identifiers if the NHS Number was missing. RESULTS: For the period 2005-2014, over 94% of birth registration and notification records were correctly linked to HES delivery records. Two per cent of the ONS birth records were incorrectly linked to the HES delivery record and 5% of ONS birth records were linked to more than one HES delivery record. Therefore, a considerable amount of time was spent in quality assuring these files. CONCLUSION: The linkage rate for birth registration and notification records to HES delivery records steadily improved from 2005 to 2014 due to improvement in the quality and completeness of patient identifiers in both HES and birth notification data.

AB - OBJECTIVES: To assess acceptability and feasibility of trial processes and the Rehabilitation Training (ReTrain) intervention including an assessment of intervention fidelity. DESIGN: A two-group, assessor-blinded, randomised controlled trial with parallel mixed methods process and economic evaluations. SETTING: Community settings across two sites in Devon. PARTICIPANTS: Eligible participants were: 18 years old or over, with a diagnosis of stroke and with self reported mobility issues, no contraindications to physical activity, discharged from National Health Service or any other formal rehabilitation programme at least 1 month before, willing to be randomised to either control or ReTrain and attend the training venue, possessing cognitive capacity and communication ability sufficient to participate. Participants were individually randomised (1:1) via a computer-generated randomisation sequence minimised for time since stroke and level of functional disability. Only outcome assessors independent of the research team were blinded to group allocation. INTERVENTIONS: ReTrain comprised (1) an introductory one-to-one session; (2) ten, twice-weekly group classes with up to two trainers and eight clients; (3) a closing one-to-one session, followed by three drop-in sessions over the subsequent 3 months. Participants received a bespoke home-based training programme. All participants received treatment as usual. The control group received an exercise after stroke advice booklet. OUTCOME MEASURES: Candidate primary outcomes included functional mobility and physical activity. RESULTS: Forty-five participants were randomised (ReTrain=23; Control=22); data were available from 40 participants at 6 months of follow-up (ReTrain=21; Control=19) and 41 at 9 months of follow-up (ReTrain=21; Control=20). We demonstrated ability to recruit and retain participants. Participants were not burdened by the requirements of the study. We were able to calculate sample estimates for candidate primary outcomes and test procedures for process and health economic evaluations. CONCLUSIONS: All objectives were fulfilled and indicated that a definitive trial of ReTrain is feasible and acceptable. TRIAL REGISTRATION NUMBER: NCT02429180; Results. PMID- 29449291 TI - Adapting and enhancing PAX Good Behavior Game for First Nations communities: a mixed-methods study protocol developed with Swampy Cree Tribal Council communities in Manitoba. AB - INTRODUCTION: High rates of mental health problems, such as suicidal behaviours, among First Nations youth in Canada are a major public health concern. The Good Behavior Game (GBG) is a school-based intervention that provides a nurturing environment for children and has been shown to promote positive outcomes. PAX Good Behavior Game (PAX GBG) is an adaptation and enhancement of the GBG. While PAX GBG has been implemented in Indigenous communities, little research exists examining the cultural and contextual appropriateness and effectiveness of the intervention in First Nations communities. METHODS AND ANALYSIS: The present paper describes a protocol of the mixed-methods approach guided by an Indigenous ethical engagement model adopted to implement, adapt and evaluate PAX GBG in First Nations communities in Manitoba, Canada. First, implementation outcomes (eg, acceptability, adoption) of PAX GBG will be evaluated using qualitative interviews with teachers, principals and community members from Swampy Cree Tribal Council (SCTC) communities. Second, by linking administrative databases to programme data from schools in 38 First Nations communities, we will compare PAX GBG and control groups to evaluate whether PAX GBG is associated with improved mental health and academic outcomes. Third, the qualitative results will help inform a cultural and contextual adaptation of PAX GBG called First Nations PAX (FN PAX). Fourth, FN PAX will be implemented in a few SCTC communities and evaluated using surveys and qualitative interviews followed by the remaining communities the subsequent year. ETHICS AND DISSEMINATION: Ethical approval was obtained from the University of Manitoba Health Research Ethics Board and will be obtained from the Health Information Privacy Committee and respective data providers for the administrative database linkages. Dissemination and knowledge translation will include community and stakeholder engagement throughout the research process, reports and presentations for policymakers and community members, presentations at scientific conferences and journal publications. PMID- 29449292 TI - Cost-effectiveness of a community-delivered multicomponent intervention compared with enhanced standard care of obese adolescents: cost-utility analysis alongside a randomised controlled trial (the HELP trial). AB - OBJECTIVE: To undertake a cost-utility analysis of a motivational multicomponent lifestyle-modification intervention in a community setting (the Healthy Eating Lifestyle Programme (HELP)) compared with enhanced standard care. DESIGN: Cost utility analysis alongside a randomised controlled trial. SETTING: Community settings in Greater London, England. PARTICIPANTS: 174 young people with obesity aged 12-19 years. INTERVENTIONS: Intervention participants received 12 one-to-one sessions across 6 months, addressing lifestyle behaviours and focusing on motivation to change and self-esteem rather than weight change, delivered by trained graduate health workers in community settings. Control participants received a single 1-hour one-to-one nurse-delivered session providing didactic weight-management advice. MAIN OUTCOME MEASURES: Mean costs and quality-adjusted life years (QALYs) per participant over a 1-year period using resource use data and utility values collected during the trial. Incremental cost-effectiveness ratio (ICER) was calculated and non-parametric bootstrapping was conducted to generate a cost-effectiveness acceptability curve (CEAC). RESULTS: Mean intervention costs per participant were L918 for HELP and L68 for enhanced standard care. There were no significant differences between the two groups in mean resource use per participant for any type of healthcare contact. Adjusted costs were significantly higher in the intervention group (mean incremental costs for HELP vs enhanced standard care L1003 (95% CI L837 to L1168)). There were no differences in adjusted QALYs between groups (mean QALYs gained 0.008 (95% CI 0.031 to 0.046)). The ICER of the HELP versus enhanced standard care was L120 630 per QALY gained. The CEAC shows that the probability that HELP was cost-effective relative to the enhanced standard care was 0.002 or 0.046, at a threshold of L20 000 or L30 000 per QALY gained. CONCLUSIONS: We did not find evidence that HELP was more effective than a single educational session in improving quality of life in a sample of adolescents with obesity. HELP was associated with higher costs, mainly due to the extra costs of delivering the intervention and therefore is not cost-effective. TRIAL REGISTRATION NUMBER: ISRCTN9984011. PMID- 29449293 TI - Feasibility, acceptability and effectiveness of an online alternative to face-to face consultation in general practice: a mixed-methods study of webGP in six Devon practices. AB - OBJECTIVES: To evaluate the feasibility, acceptability and effectiveness of webGP as piloted by six general practices. METHODS: Mixed-methods evaluation, including data extraction from practice databases, general practitioner (GP) completion of case reports, patient questionnaires and staff interviews. SETTING: General practices in NHS Northern, Eastern and Western Devon Clinical Commissioning Group's area approximately 6 months after implementing webGP (February-July 2016). PARTICIPANTS: Six practices provided consultations data; 20 GPs completed case reports (regarding 61 e-consults); 81 patients completed questionnaires; 5 GPs and 5 administrators were interviewed. OUTCOME MEASURES: Attitudes and experiences of practice staff and patients regarding webGP. RESULTS: WebGP uptake during the evaluation was small, showing no discernible impact on practice workload. The completeness of cross-sectional data on consultation workload varied between practices.GPs judged 41/61 (72%) of webGP requests to require a face-to-face or telephone consultation. Introducing webGP appeared to be associated with shifts in responsibility and workload between practice staff and between practices and patients.81/231 patients completed a postal survey (35.1% response rate). E-Consulters were somewhat younger and more likely to be employed than face-to-face respondents. WebGP appeared broadly acceptable to patients regarding timeliness and quality/experience of care provided. Similar problems were presented by all respondents. Both groups appeared equally familiar with other practice online services; e-consulters were somewhat more likely to have used them.From semistructured staff interviews, it appeared that, while largely acceptable within practice, introducing e-consults had potential for adverse interactions with pre-existing practice systems. CONCLUSIONS: There is potential to assess the impact of new systems on consultation patterns by extracting routine data from practice databases. Staff and patients noticed subtle changes to responsibilities associated with online options. Greater uptake requires good communication between practice and patients, and organisation of systems to avoid conflicts and misuse. Further research is required to evaluate the full potential of webGP in managing practice workload. PMID- 29449295 TI - Management of type 2 diabetes mellitus in people with severe mental illness: an online cross-sectional survey of healthcare professionals. AB - OBJECTIVES: To establish healthcare professionals' (HCPs) views about clinical roles, and the barriers and enablers to delivery of diabetes care for people with severe mental illness (SMI). DESIGN: Cross-sectional, postal and online survey. SETTING: Trusts within the National Health Service, mental health and diabetes charities, and professional bodies. PARTICIPANTS: HCPs who care for people with type 2 diabetes mellitus (T2DM) and/or SMI in the UK. PRIMARY AND SECONDARY OUTCOME MEASURES: The barriers, enablers and experiences of delivering T2DM care for people with SMI, informed by the Theoretical Domains Framework. RESULTS: Respondents were 273 HCPs, primarily mental health nurses (33.7%) and psychiatrists (32.2%). Only 25% of respondents had received training in managing T2DM in people with SMI. Univariate analysis found that mental health professionals felt responsible for significantly fewer recommended diabetes care standards than physical health professionals (P<0.001). For those seeing diabetes care as part of their role, the significant barriers to its delivery in the multiple regression analyses were a lack of knowledge (P=0.003); a need for training in communication and negotiation skills (P=0.04); a lack of optimism about the health of their clients (P=0.04) and their ability to manage T2DM in people with SMI (P=0.003); the threat of being disciplined (P=0.02); fear of working with people with a mental health condition (P=0.01); a lack of service user engagement (P=0.006); and a need for incentives (P=0.04). The significant enablers were an understanding of the need to tailor treatments (P=0.04) and goals (P=0.02) for people with SMI. CONCLUSIONS: This survey indicates that despite current guidelines, diabetes care in mental health settings remains peripheral. Even when diabetes care is perceived as part of an HCP's role, various individual and organisational barriers to delivering recommended T2DM care standards to people with SMI are experienced. PMID- 29449294 TI - Disease characteristics and management of hospitalised adolescents and adults with community-acquired pneumonia in China: a retrospective multicentre survey. AB - OBJECTIVES: To describe the clinical characteristics and management of patients hospitalised with community-acquired pneumonia (CAP) in China. DESIGN: This was a multicentre, retrospective, observational study. SETTING: 13 teaching hospitals in northern, central and southern China from 1 January 2014 to 31 December 2014 PARTICIPANTS: Information on hospitalised patients aged >=14 years with radiographically confirmed pneumonia with illness onset in the community was collected using standard case report forms. PRIMARY AND SECONDARY OUTCOME MEASURES: Resource use for CAP management. RESULTS: Of 14 793 patients screened, 5828 with radiographically confirmed CAP were included in the final analysis. Low mortality risk patients with a CURB-65 score 0-1 and Pneumonia Severity Index risk class I-II accounted for 81.2% (4434/5594) and 56.4% (2034/3609) patients, respectively. 21.7% (1111/5130) patients had already achieved clinical stability on admission. A definite or probable pathogen was identified only in 12.7% (738/5828) patients. 40.9% (1575/3852) patients without pseudomonal infection risk factors received antimicrobial overtreatment regimens. The median duration between clinical stability to discharge was 5.0 days with 30-day mortality of 4.2%. CONCLUSIONS: These data demonstrated the overuse of health resources in CAP management, indicating that there is potential for improvement and substantial savings to healthcare systems in China.

AB - OBJECTIVES: To compare parents' and clinicians' perspectives on the assessment and treatment of children with eczema in primary care. DESIGN: Qualitative interview study with purposive and snowball sampling and thematic analysis. SETTING: 14 general practices in the UK. PARTICIPANTS: 11 parents of children with eczema and 15 general practitioners (GPs) took part in semistructured individual interviews. RESULTS: We identified several areas of dissonance between parents and GPs. First, parents sought a 'cause' of eczema, such as an underlying allergy, whereas GPs looked to manage the symptoms of an incurable condition. Second, parents often judged eczema severity in terms of psychosocial impact, while GPs tended to focus on the appearance of the child's skin. Third, parents sought 'more natural' over-the-counter treatments or complementary medicine, which GPs felt unable to endorse because of their unknown effectiveness and potential harm. Fourth, GPs linked poor outcomes to unrealistic expectations of treatment and low adherence to topical therapy, whereas parents reported persisting with treatment and despondency with its ineffectiveness. Consultations were commonly described by parents as being dominated by the GP, with a lack of involvement in treatment decisions. GPs' management of divergent views varied, but avoidance strategies were often employed. CONCLUSIONS: Divergent views between parents and clinicians regarding the cause and treatment of childhood eczema can probably only be bridged by clinicians actively seeking out opinions and sharing rationale for their approach to treatment. Together with assessing the psychosocial as well as the physical impact of eczema, asking about current or intended use of complementary therapy and involving parents in treatment decisions, the management of eczema and patient outcomes could be improved.

PMID- 29449297 TI - Delivering safe and effective test-result communication, management and follow up: a mixed-methods study protocol. AB - INTRODUCTION: The failure to follow-up pathology and medical imaging test results poses patient-safety risks which threaten the effectiveness, quality and safety of patient care. The objective of this project is to: (1) improve the effectiveness and safety of test-result management through the establishment of clear governance processes of communication, responsibility and accountability; (2) harness health information technology (IT) to inform and monitor test-result management; (3) enhance the contribution of consumers to the establishment of safe and effective test-result management systems. METHODS AND ANALYSIS: This convergent mixed-methods project triangulates three multistage studies at seven adult hospitals and one paediatric hospital in Australia.Study 1 adopts qualitative research approaches including semistructured interviews, focus groups and ethnographic observations to gain a better understanding of test-result communication and management practices in hospitals, and to identify patient safety risks which require quality-improvement interventions.Study 2 analyses linked sets of routinely collected healthcare data to examine critical test result thresholds and test-result notification processes. A controlled before-and after study across three emergency departments will measure the impact of interventions (including the use of IT) developed to improve the safety and quality of test-result communication and management processes.Study 3 adopts a consumer-driven approach, including semistructured interviews, and the convening of consumer-reference groups and community forums. The qualitative data will identify mechanisms to enhance the role of consumers in test-management governance processes, and inform the direction of the research and the interpretation of findings. ETHICS AND DISSEMINATION: Ethical approval has been granted by the South Eastern Sydney Local Health District Human Research Ethics Committee and Macquarie University. Findings will be disseminated in academic, industry and consumer journals, newsletters and conferences. PMID- 29449300 TI - Distinct miRNA profile in prognosis of early CTCL. PMID- 29449298 TI - Clinical validation of a public health policy-making platform for hearing loss (EVOTION): protocol for a big data study. AB - INTRODUCTION: The holistic management of hearing loss (HL) requires an understanding of factors that predict hearing aid (HA) use and benefit beyond the acoustics of listening environments. Although several predictors have been identified, no study has explored the role of audiological, cognitive, behavioural and physiological data nor has any study collected real-time HA data. This study will collect 'big data', including retrospective HA logging data, prospective clinical data and real-time data via smart HAs, a mobile application and biosensors. The main objective is to enable the validation of the EVOTION platform as a public health policy-making tool for HL. METHODS AND ANALYSIS: This will be a big data international multicentre study consisting of retrospective and prospective data collection. Existing data from approximately 35 000 HA users will be extracted from clinical repositories in the UK and Denmark. For the prospective data collection, 1260 HA candidates will be recruited across four clinics in the UK and Greece. Participants will complete a battery of audiological and other assessments (measures of patient-reported HA benefit, mood, cognition, quality of life). Patients will be offered smart HAs and a mobile phone application and a subset will also be given wearable biosensors, to enable the collection of dynamic real-life HA usage data. Big data analytics will be used to detect correlations between contextualised HA usage and effectiveness, and different factors and comorbidities affecting HL, with a view to informing public health decision-making. ETHICS AND DISSEMINATION: Ethical approval was received from the London South East Research Ethics Committee (17/LO/0789), the Hippokrateion Hospital Ethics Committee (1847) and the Athens Medical Center's Ethics Committee (KM140670). Results will be disseminated through national and international events in Greece and the UK, scientific journals, newsletters, magazines and social media. Target audiences include HA users, clinicians, policy makers and the general public. TRIAL REGISTRATION NUMBER: NCT03316287; Pre results.

PMID- 29449307 TI - RAGE Deletion Confers Renoprotection by Reducing Responsiveness to Transforming Growth Factor-beta and Increasing Resistance to Apoptosis. AB - Signaling via the receptor of advanced glycation end products (RAGE)-though complex and not fully elucidated in the setting of diabetes-is considered a key injurious pathway in the development of diabetic nephropathy (DN). We report here that RAGE deletion resulted in increased expression of fibrotic markers (collagen I and IV, fibronectin) and the inflammatory marker MCP-1 in primary mouse mesangial cells (MCs) and in kidney cortex. RNA sequencing analysis in MCs from RAGE-/- and wild-type mice confirmed these observations. Nevertheless, despite these gene expression changes, decreased responsiveness to transforming growth factor-beta was identified in RAGE-/- mice. Furthermore, RAGE deletion conferred a more proliferative phenotype in MCs and reduced susceptibility to staurosporine induced apoptosis. RAGE restoration experiments in RAGE-/- MCs largely reversed these gene expression changes, resulting in reduced expression of fibrotic and inflammatory markers. This study highlights that protection against DN in RAGE knockout mice is likely to be due in part to the decreased responsiveness to growth factor stimulation and an antiapoptotic phenotype in MCs. Furthermore, it extends our understanding of the role of RAGE in the progression of DN, as RAGE seems to play a key role in modulating the sensitivity of the kidney to injurious stimuli such as prosclerotic cytokines.

PMID- 29449309 TI - ZEB1, ZEB2, and the miR-200 family form a counterregulatory network to regulate CD8+ T cell fates. AB - Long-term immunity depends partly on the establishment of memory CD8+ T cells. We identified a counterregulatory network between the homologous transcription factors ZEB1 and ZEB2 and the miR-200 microRNA family, which modulates effector CD8+ T cell fates. Unexpectedly, Zeb1 and Zeb2 had reciprocal expression patterns and were functionally uncoupled in CD8+ T cells. ZEB2 promoted terminal differentiation, whereas ZEB1 was critical for memory T cell survival and function. Interestingly, the transforming growth factor beta (TGF-beta) and miR 200 family members, which counterregulate the coordinated expression of Zeb1 and Zeb2 during the epithelial-to-mesenchymal transition, inversely regulated Zeb1 and Zeb2 expression in CD8+ T cells. TGF-beta induced and sustained Zeb1 expression in maturing memory CD8+ T cells. Meanwhile, both TGF-beta and miR-200 family members selectively inhibited Zeb2. Additionally, the miR-200 family was necessary for optimal memory CD8+ T cell formation. These data outline a previously unknown genetic pathway in CD8+ T cells that controls effector and memory cell fate decisions.

PMID- 29449312 TI - Prevalence and Prognostic Impact of Diabetes in Takotsubo Syndrome: Insights From the International, Multicenter GEIST Registry. AB - OBJECTIVE: In view of low prevalence rates, diabetes is discussed as a protective factor for the occurrence of Takotsubo syndrome (TTS). Furthermore, it was associated with improved outcome in a small single-center analysis. Therefore, this study assessed the prevalence and prognostic relevance of concomitant diabetes in TTS. RESEARCH DESIGN AND METHODS: A total of 826 patients with TTS were enrolled in an international, multicenter, registry-based study (eight centers in Italy and Germany). All-cause mortality was compared between patients with diabetes and patients without diabetes, and the independent predictive value of diabetes was evaluated in multivariate regression analysis. RESULTS: The prevalence of diabetes was 21.1% (n = 174). TTS patients with diabetes were older (P < 0.001), were more frequently male (P = 0.003), had a higher prevalence of hypertension (P < 0.001), physical triggers (P = 0.041), and typical apical ballooning (P = 0.010), had a lower left ventricular ejection fraction (P = 0.008), had a higher rate of pulmonary edema (P = 0.032), and had a longer hospital stay (P = 0.009). However, 28-day all-cause mortality did not differ between patients with diabetes and patients without diabetes (6.4% vs. 5.7%; hazard ratio [HR] 1.11 [95% CI 0.55-2.25]; P = 0.772). Longer-term follow-up after a median of 2.5 years revealed a significantly higher mortality among TTS patients with diabetes (31.4% vs. 16.5%; P < 0.001), and multivariate regression analysis identified diabetes as an independent predictor of adverse outcome (HR 1.66 [95% CI 1.16-2.39]; P = 0.006). CONCLUSIONS: Diabetes is not uncommon in patients with TTS, is associated with increased longer-term mortality rates, and is an independent predictor of adverse outcome irrespective of additional risk factors. PMID- 29449313 TI - Impaired thermogenesis and sharp increases in plasma triglyceride levels in GPIHBP1-deficient mice during cold exposure. AB - Glycosylphosphatidylinositol-anchored high density lipoprotein-binding protein 1 (GPIHBP1), an endothelial cell protein, binds LPL in the subendothelial spaces and transports it to the capillary lumen. In Gpihbp1-/- mice, LPL remains stranded in the subendothelial spaces, causing hypertriglyceridemia, but how Gpihbp1-/- mice respond to metabolic stress (e.g., cold exposure) has never been studied. In wild-type mice, cold exposure increases LPL-mediated processing of triglyceride-rich lipoproteins (TRLs) in brown adipose tissue (BAT), providing fuel for thermogenesis and leading to lower plasma triglyceride levels. We suspected that defective TRL processing in Gpihbp1-/- mice might impair thermogenesis and blunt the fall in plasma triglyceride levels. Indeed, Gpihbp1-/ mice exhibited cold intolerance, but the effects on plasma triglyceride levels were paradoxical. Rather than falling, the plasma triglyceride levels increased sharply (from ~4,000 to ~15,000 mg/dl), likely because fatty acid release by peripheral tissues drives hepatic production of TRLs that cannot be processed. We predicted that the sharp increase in plasma triglyceride levels would not occur in Gpihbp1-/-Angptl4-/- mice, where LPL activity is higher and baseline plasma triglyceride levels are lower. Indeed, the plasma triglyceride levels in Gpihbp1 /-Angptl4-/- mice fell during cold exposure. Metabolic studies revealed increased levels of TRL processing in the BAT of Gpihbp1-/-Angptl4-/- mice.

AB - BACKGROUND: Accumulating evidence from animal and human studies suggests that vitamin D is involved in many functions of the reproductive system in both genders. AIM: The aim of this review was to provide an overview on the effects of vitamin D on polycystic ovary syndrome (PCOS) in women and androgen metabolism in men. METHODS: We performed a systematic literature search in PubMed for relevant English language publications published from January 2012 until September 2017. RESULTS AND DISCUSSION: The vitamin D receptor and vitamin D-metabolizing enzymes are found in reproductive tissues of women and men. In women, vitamin D status has been associated with several features of PCOS. In detail, cross-sectional data suggest a regulatory role of vitamin D in PCOS-related aspects such as ovulatory dysfunction, insulin resistance as well as hyperandrogenism. Moreover, results from randomized controlled trials (RCTs) suggest that vitamin D supplementation may be beneficial for metabolic, endocrine and fertility aspects in PCOS. In men, vitamin D status has been associated with androgen levels and hypogonadism. Further, there is some evidence for a favorable effect of vitamin D supplementation on testosterone concentrations, although others failed to show a significant effect on testosterone levels. CONCLUSION: In summary, vitamin D deficiency is associated with adverse fertility outcomes including PCOS and hypogonadism, but the evidence is insufficient to establish causality. High quality RCTs are needed to further evaluate the effects of vitamin D supplementation in PCOS women as well as on androgen levels in men. PMID- 29449317 TI - It Takes a Village to Move a Hospital: Simulation Improves Intensive Care Team Preparedness for a Move to a New Site. AB - OBJECTIVES: To evaluate in-situ simulation to prepare a PICU to move to a new, redesigned unit. METHODS: The study setting is an academic PICU. This is a cross sectional study using in-situ simulations of common PICU admissions. Postsimulation, participants completed a survey comparing the perception of preparedness pre- and postsimulation (via a 10-point Likert scale). Participants were resurveyed 6 months postmove to assess whether effects persisted. Qualitative data were obtained via thematic review of the survey comment section and from postsimulation debriefing. RESULTS: Response rates were initially 100% and 67% at the 6-month follow-up. In the initial phase, all questions had statistically significant improvements in post- versus presimulation scores. Participants felt better prepared (presimulation: 6.20, postsimulation: 7.90, P < .001) and more confident about caring for real patients (presimulation: 5.49, postsimulation: 7.41, P < .001). They felt more comfortable working in the new unit (presimulation: 5.65, postsimulation: 7.50, P < .001) and better able to deliver safe care (presimulation: 5.85, postsimulation: 7.60, P < .001). Six months postmove, participants still believed that simulation was helpful (7.43, SD: 2.20) and still reported improved team confidence (7.36, SD: 2.11). Only 1 of 28 participants preferred less simulation. Exercises were described as helpful in identifying process and latent patient safety issues. CONCLUSIONS: Our pediatric intensive care team found simulations to be beneficial in preparation for providing care to critically ill children in a complex new setting. Simulations uncovered latent process, personnel, and patient-safety issues that were addressed before actual patient care. PMID- 29449315 TI - Metaplastic breast cancer in a patient with neurofibromatosis type 1 and somatic loss of heterozygosity. AB - Metaplastic breast carcinoma (MBC) is rare and has a poor prognosis. Here we describe genetic analysis of a 41-yr-old female patient with MBC and neurofibromatosis type I (NF1). She initially presented with pT3N1a, grade 3 MBC, but lung metastases were discovered subsequently. To identify the molecular cause of her NF1, we screened for germline mutations disrupting NF1 or SPRED1, revealing a heterozygous germline single-nucleotide variant (SNV) in exon 21 of NF1 at c.2709G>A, Chr 17: 29556342. By report, this variant disrupts pre-mRNA splicing of NF1 transcripts. No pathogenic mutations were identified in SPRED1 A potential association between MBC and NF1 was reported in eight previous cases, but none underwent detailed genomics analysis. To identify additional candidate germline variants potentially predisposing to MBC, we conducted targeted exome sequencing of 279 established cancer-causing genes in a control blood sample, disclosing four rare SNVs. Analysis of her breast tumor showed markedly altered variant allelic fractions (VAFs) for two (50%) of them, revealing somatic loss of heterozygosity (LOH) at germline SNVs. Of these, only the VAF of the pathogenic SNV in NF1 was increased in the tumor. Tumor sequencing demonstrated five somatic mutations altering TP53, BRCA1, and other genes potentially contributing to cancer formation. Because somatic LOH at certain germline SNVs can enhance their impacts, we conclude that increased allelic imbalance of the pathogenic SNV in NF1 likely contributed to tumorigenesis. Our results highlight a need to assess predisposing genetic factors and LOH that can cause rare, aggressive diseases such as MBC in NF1.

PMID- 29449318 TI - Exosomal microRNA-21-5p Mediates Mesenchymal Stem Cell Paracrine Effects on Human Cardiac Tissue Contractility. AB - RATIONALE: The promising clinical benefits of delivering human mesenchymal stem cells (hMSCs) for treating heart disease warrant a better understanding of underlying mechanisms of action. hMSC exosomes increase myocardial contractility; however, the exosomal cargo responsible for these effects remains unresolved. OBJECTIVE: This study aims to identify lead cardioactive hMSC exosomal microRNAs to provide a mechanistic basis for optimizing future stem cell-based cardiotherapies. METHODS AND RESULTS: Integrating systems biology and human engineered cardiac tissue (hECT) technologies, partial least squares regression analysis of exosomal microRNA profiling data predicted microRNA-21-5p (miR-21-5p) levels positively correlate with contractile force and calcium handling gene expression responses in hECTs treated with conditioned media from multiple cell types. Furthermore, miR-21-5p levels were significantly elevated in hECTs treated with the exosome-enriched fraction of the hMSC secretome (hMSC-exo) versus untreated controls. This motivated experimentally testing the human-specific role of miR-21-5p in hMSC-exo-mediated increases of cardiac tissue contractility. Treating hECTs with miR-21-5p alone was sufficient to recapitulate effects observed with hMSC-exo on hECT developed force and expression of associated calcium handling genes (eg, SERCA2a and L-type calcium channel). Conversely, knockdown of miR-21-5p in hMSCs significantly diminished exosomal procontractile and associated calcium handling gene expression effects on hECTs. Western blots supported miR-21-5p effects on calcium handling gene expression at the protein level, corresponding to significantly increased calcium transient amplitude and decreased decay time constant in comparison to miR-scramble control. Mechanistically, cotreating with miR-21-5p and LY294002, a PI3K inhibitor, suppressed these effects. Finally, mathematical simulations predicted the translational capacity for miR-21-5p treatment to restore calcium handling in mature ischemic adult human cardiomyocytes. CONCLUSIONS: miR-21-5p plays a key role in hMSC-exo-mediated effects on cardiac contractility and calcium handling, likely via PI3K signaling. These findings may open new avenues of research to harness the role of miR-21-5p in optimizing future stem cell-based cardiotherapies.

PMID- 29449322 TI - Actin retrograde flow controls natural killer cell response by regulating the conformation state of SHP-1. AB - Natural killer (NK) cells are a powerful weapon against viral infections and tumor growth. Although the actin-myosin (actomyosin) cytoskeleton is crucial for a variety of cellular processes, the role of mechanotransduction, the conversion of actomyosin mechanical forces into signaling cascades, was never explored in NK cells. Here, we demonstrate that actomyosin retrograde flow (ARF) controls the immune response of primary human NK cells through a novel interaction between beta-actin and the SH2-domain-containing protein tyrosine phosphatase-1 (SHP-1), converting its conformation state, and thereby regulating NK cell cytotoxicity. Our results identify ARF as a master regulator of the NK cell immune response. Since actin dynamics occur in multiple cellular processes, this mechanism might also regulate the activity of SHP-1 in additional cellular systems. PMID- 29449324 TI - STIM1 (c)AMPs up melanogenesis. PMID- 29449323 TI - Structural basis of siRNA recognition by TRBP double-stranded RNA binding domains. AB - The accurate cleavage of pre-micro(mi)RNAs by Dicer and mi/siRNA guide strand selection are important steps in forming the RNA-induced silencing complex (RISC). The role of Dicer binding partner TRBP in these processes remains poorly understood. Here, we solved the solution structure of the two N-terminal dsRNA binding domains (dsRBDs) of TRBP in complex with a functionally asymmetric siRNA using NMR, EPR, and single-molecule spectroscopy. We find that siRNA recognition by the dsRBDs is not sequence-specific but rather depends on the RNA shape. The two dsRBDs can swap their binding sites, giving rise to two equally populated, pseudo-symmetrical complexes, showing that TRBP is not a primary sensor of siRNA asymmetry. Using our structure to model a Dicer-TRBP-siRNA ternary complex, we show that TRBP's dsRBDs and Dicer's RNase III domains bind a canonical 19 base pair siRNA on opposite sides, supporting a mechanism whereby TRBP influences Dicer-mediated cleavage accuracy by binding the dsRNA region of the pre-miRNA during Dicer cleavage. PMID- 29449325 TI - Quantitative Flow Ratio Identifies Nonculprit Coronary Lesions Requiring Revascularization in Patients With ST-Segment-Elevation Myocardial Infarction and Multivessel Disease. AB - BACKGROUND: The nonculprit lesion (NCL) management in ST-segment-elevation myocardial infarction patients with multivessel disease is debated. We sought to assess whether quantitative flow ratio (QFR), a noninvasive tool to identify potentially flow-limiting lesions, may be reliable in this scenario. METHODS AND RESULTS: The present proof-of-concept study is based on a 3-step process: (1) identification of the QFR reproducibility in NCLs assessment (cohort A, n=31); (2) prospective validation of QFR diagnostic accuracy in respect to fractional flow reserve (cohort B, n=45); and (3) investigation of long-term clinical outcomes of NCLs stratified according to QFR (cohort C, n=110). A blinded core laboratory computed QFR values for all NCLs. Cohort A showed a good correlation and agreement between QFR values at index (acute) and at staged (subacute, 3-4 days later) procedures (r=0.98; 95% confidence interval, 0.96-0.99; mean difference, 0.004 [-0.027 to 0.34]). The inter-rater agreement was kappa=0.9. In cohort B, fractional flow reserve and QFR identified 16 (33%) and 17 (35%) NCLs potentially flow limiting. Sensitivity, specificity, negative, and positive predictive values were 88%, 97%, 94%, and 94%. The area under the receiver operating characteristics curve was 0.96 (95% confidence interval, 0.89-0.99). Finally, in cohort C, we identified 110 ST-segment-elevation myocardial infarction patients where at least 1 NCL was left untreated. Patients with NCLs showing a QFR value <=0.80 were at higher risk of adverse events (hazard ratio, 2.3; 95% confidence interval, 1.2-4.5; P=0.01). CONCLUSIONS: In a limited and selected study population, our study showed that QFR computation may be a safe and reliable tool to guide coronary revascularization of NCLs in ST-segment elevation myocardial infarction patients.

PMID- 29449326 TI - Fatty acid synthase mediates EGFR palmitoylation in EGFR mutated non-small cell lung cancer. AB - Metabolic reprogramming is widely known as a hallmark of cancer cells to allow adaptation of cells to sustain survival signals. In this report, we describe a novel oncogenic signaling pathway exclusively acting in mutated epidermal growth factor receptor (EGFR) non-small cell lung cancer (NSCLC) with acquired tyrosine kinase inhibitor (TKI) resistance. Mutated EGFR mediates TKI resistance through regulation of the fatty acid synthase (FASN), which produces 16-C saturated fatty acid palmitate. Our work shows that the persistent signaling by mutated EGFR in TKI-resistant tumor cells relies on EGFR palmitoylation and can be targeted by Orlistat, an FDA-approved anti-obesity drug. Inhibition of FASN with Orlistat induces EGFR ubiquitination and abrogates EGFR mutant signaling, and reduces tumor growths both in culture systems and in vivo Together, our data provide compelling evidence on the functional interrelationship between mutated EGFR and FASN and that the fatty acid metabolism pathway is a candidate target for acquired TKI-resistant EGFR mutant NSCLC patients. PMID- 29449328 TI - Cladribine for multiple sclerosis. AB - In the UK, there are twelve disease-modifying drugs licensed for various forms of multiple sclerosis (MS), of which three are oral therapies. An oral formulation of cladribine (Mavenclad - Merck Serono Europe Limited) was recently licensed by the European Medicines Agency (EMA) for the treatment of adult patients with highly active relapsing MS.1,2 It is claimed to be "an innovatively simple approach" for treating this form of MS and "the only disease modifying therapy that can deliver and sustain 4 years of disease control with a maximum of 20 days oral treatment in the first 2 years."3 Here, we consider the evidence for its use in the treatment of highly active relapsing MS. PMID- 29449330 TI - Therapeutic Lowering of Lipoprotein(a): A Role for Pharmacogenetics? PMID- 29449329 TI - Impact of Apolipoprotein(a) Isoform Size on Lipoprotein(a) Lowering in the HPS2 THRIVE Study. AB - BACKGROUND: Genetic studies have shown lipoprotein(a) (Lp[a]) to be an important causal risk factor for coronary disease. Apolipoprotein(a) isoform size is the chief determinant of Lp(a) levels, but its impact on the benefits of therapies that lower Lp(a) remains unclear. METHODS: HPS2-THRIVE (Heart Protection Study 2 Treatment of HDL to Reduce the Incidence of Vascular Events) is a randomized trial of niacin-laropiprant versus placebo on a background of simvastatin therapy. Plasma Lp(a) levels at baseline and 1 year post-randomization were measured in 3978 participants from the United Kingdom and China. Apolipoprotein(a) isoform size, estimated by the number of kringle IV domains, was measured by agarose gel electrophoresis and the predominantly expressed isoform identified. RESULTS: Allocation to niacin-laropiprant reduced mean Lp(a) by 12 (SE, 1) nmol/L overall and 34 (6) nmol/L in the top quintile by baseline Lp(a) level (Lp[a] >=128 nmol/L). The mean proportional reduction in Lp(a) with niacin-laropiprant was 31% but varied strongly with predominant apolipoprotein(a) isoform size (PTrend=4*10-29) and was only 18% in the quintile with the highest baseline Lp(a) level and low isoform size. Estimates from genetic studies suggest that these Lp(a) reductions during the short term of the trial might yield proportional reductions in coronary risk of ~2% overall and 6% in the top quintile by Lp(a) levels. CONCLUSIONS: Proportional reductions in Lp(a) were dependent on apolipoprotein(a) isoform size. Taking this into account, the likely benefits of niacin-laropiprant on coronary risk through Lp(a) lowering are small. Novel therapies that reduce high Lp(a) levels by at least 80 nmol/L (~40%) may be needed to produce worthwhile benefits in people at the highest risk because of Lp(a).

PMID- 29449331 TI - Lipid-Lowering Therapy With Ezetimibe Decreases Spontaneous Atherothrombotic Occlusions in a Rabbit Model of Plaque Erosion: A Role of Serum Oxysterols. AB - OBJECTIVE: Plaque erosion is increasing its importance as one of the mechanisms of acute coronary syndromes in this statin era. However, the clinical efficacy of currently used lipid-lowering agents in the prevention of thrombotic complications associated with plaque erosion has not been clarified. Therefore, we examined the therapeutic effects of ezetimibe or rosuvastatin monotherapy on spontaneous atherothrombotic occlusion. APPROACH AND RESULTS: Femoral arteries of Japanese white rabbits, fed a high-cholesterol diet, were injured by balloon catheter, and then angiotensin II was continuously administrated. In 94% of these arteries, spontaneous thrombotic occlusions were observed after 5 weeks (median) of balloon injury. Histochemical analyses indicated that the injured arteries had similar pathological features to human plaque erosions; (1) spontaneous thrombotic occlusion, (2) lack of endothelial cells, and (3) tissue factor expression in vascular smooth muscle cells. Ezetimibe (1.0 mg/kg per day), but not rosuvastatin (0.6 mg/kg per day), significantly decreased thrombotic occlusion of arteries accompanied with accelerated re-endothelialization and the decreases of serum oxysterols despite the comparable on-treatment serum cholesterol levels. The 7-ketocholesterol inhibited the migration of human umbilical vein endothelial cells. Both 7-ketocholesterol and 27 hydroxycholesterol increased tissue factor expression in cultured rat vascular smooth muscle cells. Tissue factor expression was also induced by serum from vehicle- or rosuvastatin-treated rabbits, but the induction was attenuated with serum from ezetimibe-treated rabbits. CONCLUSIONS: We have established a novel rabbit model of spontaneous atherothromobotic occlusion without plaque rupture that is feasible to test the therapeutic effects of various pharmacotherapies. Ezetimibe may decrease atherothrombotic complications after superficial plaque erosion by reducing serum oxysterols. PMID- 29449332 TI - Inhibition of Endothelial NOTCH1 Signaling Attenuates Inflammation by Reducing Cytokine-Mediated Histone Acetylation at Inflammatory Enhancers. AB - OBJECTIVE: Endothelial upregulation of adhesion molecules serves to recruit leukocytes to inflammatory sites and appears to be promoted by NOTCH1; however, current models based on interactions between active NOTCH1 and NF-kappaB components cannot explain the transcriptional selectivity exerted by NOTCH1 in this context. APPROACH AND RESULTS: Observing that Cre/Lox-induced conditional mutations of endothelial Notch modulated inflammation in murine contact hypersensitivity, we found that IL (interleukin)-1beta stimulation induced rapid recruitment of RELA (v-rel avian reticuloendotheliosis viral oncogene homolog A) to genomic sites occupied by NOTCH1-RBPJ (recombination signal-binding protein for immunoglobulin kappa J region) and that NOTCH1 knockdown reduced histone H3K27 acetylation at a subset of NF-kappaB-directed inflammatory enhancers. CONCLUSIONS: Our findings reveal that NOTCH1 signaling supports the expression of a subset of inflammatory genes at the enhancer level and demonstrate how key signaling pathways converge on chromatin to coordinate the transition to an infla mmatory endothelial phenotype. PMID- 29449333 TI - Endothelial Cell Autonomous Role of Akt1: Regulation of Vascular Tone and Ischemia-Induced Arteriogenesis. AB - OBJECTIVE: The importance of PI3K/Akt signaling in the vasculature has been demonstrated in several models, as global loss of Akt1 results in impaired postnatal ischemia- and VEGF-induced angiogenesis. The ubiquitous expression of Akt1, however, raises the possibility of cell-type-dependent Akt1-driven actions, thereby necessitating tissue-specific characterization. APPROACH AND RESULTS: Herein, we used an inducible, endothelial-specific Akt1-deleted adult mouse model (Akt1iECKO) to characterize the endothelial cell autonomous functions of Akt1 in the vascular system. Endothelial-targeted ablation of Akt1 reduces eNOS (endothelial nitric oxide synthase) phosphorylation and promotes both increased vascular contractility in isolated vessels and elevated diastolic blood pressures throughout the diurnal cycle in vivo. Furthermore, Akt1iECKO mice subject to the hindlimb ischemia model display impaired blood flow and decreased arteriogenesis. CONCLUSIONS: Endothelial Akt1 signaling is necessary for ischemic resolution post injury and likely reflects the consequence of NO insufficiency critical for vascular repair. PMID- 29449334 TI - RGC-32 (Response Gene to Complement 32) Deficiency Protects Endothelial Cells From Inflammation and Attenuates Atherosclerosis. AB - OBJECTIVE: The objective of this study is to determine the role and underlying mechanisms of RGC-32 (response gene to complement 32 protein) in atherogenesis. APPROACH AND RESULTS: RGC-32 was mainly expressed in endothelial cells of atherosclerotic lesions in both ApoE-/- (apolipoprotein E deficient) mice and human patients. Rgc-32 deficiency (Rgc32-/-) attenuated the high-fat diet-induced and spontaneously developed atherosclerotic lesions in ApoE-/- mice without affecting serum cholesterol concentration. Rgc32-/- seemed to decrease the macrophage content without altering collagen and smooth muscle contents or lesional macrophage proliferation in the lesions. Transplantation of WT (wild type) mouse bone marrow to lethally irradiated Rgc32-/- mice did not alter Rgc32 /--caused reduction of lesion formation and macrophage accumulation, suggesting that RGC-32 in resident vascular cells, but not the macrophages, plays a critical role in the atherogenesis. Of importance, Rgc32-/- decreased the expression of ICAM-1 (intercellular adhesion molecule-1) and VCAM-1 (vascular cell adhesion molecule-1) in endothelial cells both in vivo and in vitro, resulting in a decrease in TNF-alpha (tumor necrosis factor-alpha)-induced monocyte-endothelial cell interaction. Mechanistically, RGC-32 mediated the ICAM-1 and VCAM-1 expression, at least partially, through NF (nuclear factor)-kappaB signaling pathway. RGC-32 directly interacted with NF-kappaB and facilitated its nuclear translocation and enhanced TNF-alpha-induced NF-kappaB binding to ICAM-1 and VCAM 1 promoters. CONCLUSIONS: RGC-32 mediates atherogenesis by facilitating monocyte endothelial cell interaction via the induction of endothelial ICAM-1 and VCAM-1 expression, at least partially, through NF-kappaB signaling pathway. PMID- 29449335 TI - Bempedoic Acid Lowers Low-Density Lipoprotein Cholesterol and Attenuates Atherosclerosis in Low-Density Lipoprotein Receptor-Deficient (LDLR+/- and LDLR-/ ) Yucatan Miniature Pigs. AB - OBJECTIVE: Bempedoic acid (BemA; ETC-1002) is a novel drug that targets hepatic ATP-citrate lyase to reduce cholesterol biosynthesis. In phase 2 studies, BemA lowers elevated low-density lipoprotein cholesterol (LDL-C) in hypercholesterolemic patients. In the present study, we tested the ability of BemA to decrease plasma cholesterol and LDL-C and attenuate atherosclerosis in a large animal model of familial hypercholesterolemia. APPROACH AND RESULTS: Gene targeting has been used to generate Yucatan miniature pigs heterozygous (LDLR+/-) or homozygous (LDLR-/-) for LDL receptor deficiency (ExeGen). LDLR+/- and LDLR-/- pigs were fed a high-fat, cholesterol-containing diet (34% kcal fat; 0.2% cholesterol) and orally administered placebo or BemA for 160 days. In LDLR+/- pigs, compared with placebo, BemA decreased plasma cholesterol and LDL-C up to 40% and 61%, respectively. In LDLR-/- pigs, in which plasma cholesterol and LDL-C were 5-fold higher than in LDLR+/- pigs, BemA decreased plasma cholesterol and LDL-C up to 27% and 29%, respectively. Plasma levels of triglycerides and high density lipoprotein cholesterol, fasting glucose and insulin, and liver lipids were unaffected by treatment in either genotype. In the aorta of LDLR+/- pigs, BemA robustly attenuated en face raised lesion area (-58%) and left anterior descending coronary artery cross-sectional lesion area (-40%). In LDLR-/- pigs, in which lesions were substantially more advanced, BemA decreased aortic lesion area (-47%) and left anterior descending coronary artery lesion area (-48%). CONCLUSIONS: In a large animal model of LDLR deficiency and atherosclerosis, long term treatment with BemA reduces LDL-C and attenuates the development of aortic and coronary atherosclerosis in both LDLR+/- and LDLR-/- miniature pigs.

PMID- 29449337 TI - ALK1 Loss Results in Vascular Hyperplasia in Mice and Humans Through PI3K Activation. AB - OBJECTIVE: ALK1 (activin-receptor like kinase 1) is an endothelial cell restricted receptor with high affinity for BMP (bone morphogenetic protein) 9 TGF beta (transforming growth factor-beta) family member. Loss-of-function mutations in ALK1 cause a subtype of hereditary hemorrhagic telangiectasia-a rare disease characterized by vasculature malformations. Therapeutic strategies are aimed at reducing potential complications because of vascular malformations, but currently, there is no curative treatment for hereditary hemorrhagic telangiectasia. APPROACH AND RESULTS: In this work, we report that a reduction in ALK1 gene dosage (heterozygous ALK1+/- mice) results in enhanced retinal endothelial cell proliferation and vascular hyperplasia at the sprouting front. We found that BMP9/ALK1 represses VEGF (vascular endothelial growth factor) mediated PI3K (phosphatidylinositol 3-kinase) by promoting the activity of the PTEN (phosphatase and tensin homolog). Consequently, loss of ALK1 function in endothelial cells results in increased activity of the PI3K pathway. These results were confirmed in cutaneous telangiectasia biopsies of patients with hereditary hemorrhagic telangiectasia 2, in which we also detected an increase in endothelial cell proliferation linked to an increase on the PI3K pathway. In mice, genetic and pharmacological inhibition of PI3K is sufficient to abolish the vascular hyperplasia of ALK1+/- retinas and in turn normalize the vasculature. CONCLUSIONS: Overall, our results indicate that the BMP9/ALK1 hub critically mediates vascular quiescence by limiting PI3K signaling and suggest that PI3K inhibitors could be used as novel therapeutic agents to treat hereditary hemorrhagic telangiectasia. PMID- 29449338 TI - Status of Hypertension in China: Results From the China Hypertension Survey, 2012 2015. AB - BACKGROUND: Although the prevalence of hypertension (HTN) continues to increase in developing countries, including China, recent data are lacking. A nationwide survey was conducted from October 2012 to December 2015 to assess the prevalence of HTN in China. METHODS: A stratified multistage random sampling method was used to obtain a nationally representative sample of 451 755 residents >=18 years of age from 31 provinces in mainland China from October 2012 to December 2015. Blood pressure (BP) was measured after resting for 5 minutes by trained staff using a validated oscillometric BP monitor. HTN was defined as systolic BP (SBP) >=140 mm Hg/or diastolic BP (DBP) >=90 mm Hg or use of antihypertensive medication within 2 weeks. Pre-HTN was defined as SBP 120 to 139 mm Hg and DBP 80 to 89 mm Hg without antihypertensive medication. HTN control was defined as SBP <140 mm Hg and DBP<90 mm Hg. In addition, the prevalence of HTN (SBP >=130 or DBP >=80 mm Hg) and control rate (SBP <130 and DBP <80 mm Hg) of HTN were also estimated according to the 2017 American College of Cardiology/American Heart Association High Blood Pressure Guideline. RESULTS: Overall, 23.2% (~244.5 million) of the Chinese adult population >=18 years of age had HTN, and another 41.3% (~435.3 million) had pre-HTN according to the Chinese guideline. There were no significant differences of HTN prevalence between urban and rural residents (23.4% versus 23.1%, P=0.819). Among individuals with HTN, 46.9% were aware of their condition, 40.7% were taking prescribed antihypertensive medications, and 15.3% had controlled HTN. Calcium channel blockers were the most commonly used antihypertensive medication (46.5%) as monotherapy, and 31.7% of treated hypertensive patients used >=2 medications. The prevalence of HTN based on the 2017 American College of Cardiology/American Heart Association guideline was twice as high as that based on 2010 Chinese guideline (46.4%), whereas the control rate fell to 3.0%. CONCLUSIONS: In China, there is a high prevalence of HTN and pre-HTN, and awareness, treatment, and control of HTN were low. Management of medical therapy for HTN needs to improve.

PMID- 29449342 TI - Epilepsy in Children After Pandemic Influenza Vaccination. AB - OBJECTIVES: To determine if pandemic influenza vaccination was associated with an increased risk of epilepsy in children. METHODS: Information from Norwegian registries from 2006 through 2014 on all children <18 years living in Norway on October 1, 2009 was used in Cox regression models to estimate hazard ratios for incident epilepsy after vaccination. A self-controlled case series analysis was used to estimate incidence rate ratios in defined risk periods after pandemic vaccination. RESULTS: In Norway, the main period of the influenza A subtype H1N1 pandemic was from October 2009 to December 2009. On October 1, 2009, 1 154 113 children <18 years of age were registered as residents in Norway. Of these, 572 875 (50.7%) were vaccinated against pandemic influenza. From October 2009 through 2014 there were 3628 new cases of epilepsy (incidence rate 6.09 per 10 000 person years). The risk of epilepsy was not increased after vaccination: hazard ratio: 1.07; 95% confidence interval: 0.94-1.23. Results from the self-controlled case series analysis supported the finding of no association between vaccination and subsequent epilepsy. CONCLUSIONS: Pandemic influenza vaccination was not associated with increased risk of epilepsy. Concerns about pandemic vaccination causing epilepsy in children seem to be unwarranted. PMID- 29449343 TI - Extrahepatic angiogenesis hinders recovery of portal hypertension and collaterals in rats with cirrhosis resolution. AB - Liver cirrhosis is characterized by portal hypertension. However, the alteration of portal hypertension-related derangements during cirrhosis resolution is not well known. The present study aimed to establish animal models with cirrhosis resolution and to investigate the relevant changes during this process. Male Sprague-Dawley rats were applied. In reverse thioacetamide (rTAA) model, rats were randomly allocated into four groups with control, thioacetamide (TAA) cirrhosis and rTAA groups that discontinued TAA for 4 or 8 weeks after cirrhosis induction. In reverse bile duct ligation (rBDL) model, rats received choledochoduodenal shunt surgery upon the establishment of cirrhosis and 4, 8, or 16 weeks were allowed after the surgery. At the end, portal hypertension-related parameters were evaluated. Cirrhosis resolution was observed in rTAA groups. Portal pressure (PP) decreased after cirrhosis resolution but remained higher than control group (control, TAA, rTAA4, rTAA8 (mmHg): 5.4 +/- 0.3, 12.9 +/- 0.3, 8.6 +/- 0.4, 7.6 +/- 0.6). Further survey found the increased splanchnic blood flow did not reduce during cirrhosis resolution. The extrahepatic pathological angiogenesis was not ameliorated (% of mesenteric window area: 1.2 +/- 0.3, 7.3 +/- 1.1, 8.3 +/- 1.0, 11.3 +/- 2.7). In collateral system, the shunting degree reduced while the vessels structure remained. The vascular contractility of all systems and nitric oxide (NO) production were normalized. In rBDL series, PP decreased in rBDL16 groups but the extrahepatic angiogenesis persisted. In conclusion, cirrhosis resolution attenuates but not completely normalizes portal hypertension because of persistently high splanchnic inflow and angiogenesis. In clinical setting, vascular complications such as varices could persist after cirrhosis resolution and further investigation to define the follow-up and treatment strategies is anticipated. PMID- 29449344 TI - Defeating Major Contaminants in Fe3+- Immobilized Metal Ion Affinity Chromatography (IMAC) Phosphopeptide Enrichment. AB - Here we demonstrate that biomolecular contaminants, such as nucleic acid molecules, can seriously interfere with immobilized metal ion affinity chromatography (IMAC)-based phosphopeptide enrichments. We address and largely solve this issue, developing a robust protocol implementing methanol/chloroform protein precipitation and enzymatic digestion using benzonase, which degrades all forms of DNA and RNA, before IMAC-column loading. This simple procedure resulted in a drastic increase of enrichment sensitivity, enabling the identification of around 17,000 unique phosphopeptides and 12,500 unambiguously localized phosphosites in human cell-lines from a single LC-MS/MS run, constituting a 50% increase when compared with the standard protocol. The improved protocol was also applied to bacterial samples, increasing the number of identified bacterial phosphopeptides even more strikingly, by a factor 10, when compared with the standard protocol. For E. coli we detected around 1300 unambiguously localized phosphosites per LC-MS/MS run. The preparation of these ultra-pure phosphopeptide samples only requires marginal extra costs and sample preparation time and should thus be adoptable by every laboratory active in the field of phosphoproteomics.

AB - The opportunistic pathogen non-typeable Haemophilus influenzae (NTHi) plays an important role in many chronic respiratory diseases including otitis media, chronic rhinosinusitis, cystic fibrosis and chronic obstructive pulmonary disease. Biofilm formation has been implicated in NTHi colonisation, persistence of infection and recalcitrance towards antimicrobials. There is therefore a pressing need for the development of novel treatment strategies that are effective against NTHi biofilm-associated diseases. SurgihoneyRO is a honey-based product that has been bioengineered to enable the slow release of H2O2, a reactive oxygen species to which H. influenzae is susceptible. Treatment of established NTHi biofilms with SurgihoneyRO significantly reduced biofilm viability through enhanced H2O2 production and was shown to be more effective than the conventional antibiotic co-amoxiclav.

AB - Shikonin, a natural naphthoquinone isolated from a traditional Chinese medicinal herb, which exerts anticancer effects in various cancers. However, the molecular mechanisms underlying the therapeutic effects of shikonin against endometrioid endometrial cancer (EEC) have not yet been fully elucidated. Herein, we investigated anticancer effects of shikonin on EEC cells and explored the underlying molecular mechanism. We observed that shikonin inhibits proliferation in human EEC cell lines in a dose-dependent manner. Moreover, shikonin-induced apoptosis was characterized by the up-regulation of the pro-apoptotic proteins cleaved-Caspase-3 and Bax, and the down-regulation of the anti-apoptotic protein Bcl-2. Microarray analyses demonstrated that shikonin induces many miRNAs' dysregulation, and miR-106b was one of the miRNAs being most significantly down regulated. miR-106b was identified to exert procancer effect in various cancers, but in EEC remains unclear. We first confirmed that miR-106b is up-regulated in EEC tissues and cells, and knockdown of miR-106b suppresses proliferation and promotes apoptosis. Meanwhile, our results validated that the restored expression of miR-106b abrogates the antiproliferative and pro-apoptotic effects of shikonin. We also identified that miR-106b targets phosphatase and tensin homolog (PTEN), a tumor suppressor gene, which in turn modulates AKT/mTOR signaling pathway. Our findings indicated that shikonin inhibits proliferation and promotes apoptosis in human EEC cells by modulating the miR-106b/PTEN/AKT/mTOR signaling pathway, suggesting shikonin could act a potential therapeutic agent in the EEC treatment. PMID- 29449347 TI - Association of tumor necrosis factor-alpha (TNF-alpha) gene promoter polymorphisms with aggressive and chronic periodontitis in the eastern Indian population. AB - Background: Periodontitis is a very common inflammatory oral disease. Tumor necrosis factor-alpha (TNF-alpha) is a cytokine that has been involved with the gingival tissue destruction and remodeling occurrence. We investigated the association of single nucleotide polymorphisms (SNPs) in TNF-alpha gene promoter region with the susceptibility of aggressive and chronic periodontitis in the eastern Indian population.Methods: A total of 397 DNA samples from venous blood were isolated. 40 individuals were aggressive periodontitis patients, 157 were identified chronic periodontitis patients, and the remaining 200 were healthy individuals. Five SNPs of TNF-alpha at promoter region (rs361525, rs1800629, rs1799724, rs1800630, and rs1799964) were genotyped by PCR-sequencing in periodontitis patients and control subjects.Results: rs1800629 (-308G/A) polymorphism was more frequent in both aggressive and chronic periodontitis patients compared with the control population, though the allele frequency was different only in aggressive periodontitis patients. On the other hand, both the genotypic and allelic variation of rs361525 (-238G/A) polymorphism were found significantly less frequently in aggressive and chronic periodontitis than in controls. The other polymorphisms like rs1799724 (-857C/T) and rs1799964 ( 1031T/C) were significantly different between chronic periodontitis patients and control subjects.Conclusion: The findings suggest that the rs1800629 (-308G/A) polymorphism of TNF-alpha gene is associated with both aggressive and chronic periodontitis while rs1799724 (-857C/T) and rs1799964 (-1031T/C) polymorphisms of TNF-alpha gene is associated only with the increased susceptibility to chronic periodontitis. PMID- 29449348 TI - Mitotic waves in the early embryogenesis of Drosophila: Bistability traded for speed. AB - Early embryogenesis of most metazoans is characterized by rapid and synchronous cleavage divisions. Chemical waves of Cdk1 activity were previously shown to spread across Drosophila embryos, and the underlying molecular processes were dissected. Here, we present the theory of the physical mechanisms that control Cdk1 waves in Drosophila The in vivo dynamics of Cdk1 are captured by a transiently bistable reaction-diffusion model, where time-dependent reaction terms account for the growing level of cyclins and Cdk1 activation across the cell cycle. We identify two distinct regimes. The first one is observed in mutants of the mitotic switch. There, waves are triggered by the classical mechanism of a stable state invading a metastable one. Conversely, waves in wild type reflect a transient phase that preserves the Cdk1 spatial gradients while the overall level of Cdk1 activity is swept upward by the time-dependent reaction terms. This unique mechanism generates a wave-like spreading that differs from bistable waves for its dependence on dynamic parameters and its faster speed. Namely, the speed of "sweep" waves strikingly decreases as the strength of the reaction terms increases and scales as the powers 3/4, -1/2, and 7/12 of Cdk1 molecular diffusivity, noise amplitude, and rate of increase of Cdk1 activity in the cell-cycle S phase, respectively. Theoretical predictions are supported by numerical simulations and experiments that couple quantitative measurements of Cdk1 activity and genetic perturbations of the accumulation rate of cyclins. Finally, our analysis bears upon the inhibition required to suppress Cdk1 waves at the cell-cycle pause for the maternal-to-zygotic transition.

PMID- 29449351 TI - Regional variation and predictors of over-registration in English primary care in 2014: a spatial analysis. AB - BACKGROUND: There are more people registered with a general practice in England than are estimated to be resident in the country. The reasons behind this are not fully understood. We investigated the levels of over-registration (or under registration) in English primary care, their regional variability and their association with population and geographical characteristics. METHODS: This was a cross-sectional study using mid-year population estimates for 2014 and general practice populations for the same year. We calculated levels of patient registration with English primary care, in relation to census-derived population estimates, at various geographical levels of interest: regions, clinical commissioning groups and lower super output areas (LSOAs, 2011 census derived geographical areas of 1500 people on average). We used linear regressions to investigate the relationship between levels of registration and area deprivation, urbanicity, ethnicity, age, sex and mean distance to practice. RESULTS: The total over-registration rate for England was 3.9% (2 097 101 people) but there was wide regional variability. London had significantly higher levels of over-registration (6.0% and 515 063 people) than other areas in England. Higher levels of over registration at the LSOA level were associated with greater proportions of non White British residents, women, elderly people and higher levels of social deprivation. CONCLUSION: Our findings indicate that high mobility and health need may be the underlying causes of over-registrations. The regional variation in over-registration, with London being an outlier, points towards potential inequalities in resourcing of primary care and the ability of the National Health Service to adequately match funding to population need. PMID- 29449352 TI - Association between short sleep duration and carotid atherosclerosis modified by age in a Chinese community population. AB - BACKGROUND AND AIM: Short sleep duration is a risk factor of cardiovascular disorder; however, the association between short sleep duration and carotid atherosclerosis has not been completely characterised. The aim of this study is to investigate the association between short sleep duration and carotid atherosclerosis. METHODS: We used the cross-sectional data collected between May 2014 and July 2014, which were based on a cardiovascular disease cohort study including 3798 participants aged 40 years and older who are residents of Beijing, China. We used logistic regression models to examine the associations between sleep duration and carotid atherosclerosis. RESULTS: After the adjustment of covariates, short sleep duration (less than 5 hours per night) was found to be associated with carotid atherosclerosis, and it also elevated the risk of, in both terms, the increment of prevalence (OR=1.31, P<0.05) and the quantity of carotid plaques (OR=1.28, P<0.05). When age was also taken into consideration, the largest association, in both terms of prevalence (OR=3.46, P<0.01) and the number of carotid plaques (OR=4.23, P<0.01), was found in subjects over the age of 60 with short sleep duration. CONCLUSION: In conclusion, sleep duration less than 5 hours per night is associated with a higher risk of carotid atherosclerosis compared with subjects who sleeps for 5 or over 5 hours per night, and the association may be modified by age. PMID- 29449353 TI - Ten-Year Clinical Outcome After Circumferential Pulmonary Vein Isolation Utilizing the Hamburg Approach in Patients With Symptomatic Drug-Refractory Paroxysmal Atrial Fibrillation. AB - BACKGROUND: Circumferential pulmonary vein isolation (CPVI) is increasingly performed for the treatment of symptomatic drug-refractory paroxysmal atrial fibrillation. Long-term data for >10 years after CPVI are sparse. We investigated the long-term clinical outcome and progression of paroxysmal atrial fibrillation after double-lasso and 3-dimensional electroanatomical mapping-guided CPVI. METHODS AND RESULTS: From 2003 to 2004, 161 patients (mean age: 60+/-10 years) with symptomatic drug-refractory paroxysmal atrial fibrillation were prospectively enrolled and underwent electroanatomical mapping-guided CPVI. Right sided and left-sided continuous circular lesions encircling the ipsilateral pulmonary veins were placed with irrigated radiofrequency energy. The procedural end point was the absence of pulmonary vein spikes 30 minutes after CPVI verified by 2 spiral catheters placed within the ipsilateral pulmonary veins (double-lasso technique). Major periprocedural complications occurred in 5 of 161 patients (3.1%). Follow-up was based on outpatient clinic visits, including Holter-ECGs and telephonic interviews. After a single procedure and median follow-up of 129.0 months (interquartile range, 124.7-133.1 months), stable sinus rhythm was present in 53 of 161 (32.9%) patients. Multiprocedural outcome after a mean of 1.73+/-0.9 procedures and a median follow-up of 123.4 months (interquartile range, 61.0 131.0 months) resulted in stable sinus rhythm in 101 of 161 patients (62.7%). Progression toward persistent atrial fibrillation was observed in 10 of 161 patients (6.2%). CONCLUSION: Ten-year single-procedural outcome of CPVI in patients with paroxysmal atrial fibrillation resulted in stable sinus rhythm in 32.9% and in 62.7% of patients after multiple procedures. The progression rate to persistent AF was remarkably low. PMID- 29449354 TI - High-Resolution Infrared Thermography of Esophageal Temperature During Radiofrequency Ablation of Atrial Fibrillation. AB - BACKGROUND: Catheter ablation for atrial fibrillation has potential to cause esophageal thermal injury. Esophageal temperature monitoring during ablation is commonly used; however, it has not eliminated thermal injuries, possibly because conventional sensors have poor spatial sampling and response characteristics. To enhance understanding of temperature dynamics that may underlie esophageal injury, we tested a high-resolution, intrabody, infrared thermography catheter to continuously image esophageal temperatures during ablation. METHODS AND RESULTS: Atrial fibrillation ablation patients were instrumented with a flexible, 9F infrared temperature catheter inserted nasally (n=8) or orally (n=8) into the esophagus adjacent to the left atrium. Ablation was performed while the infrared catheter continuously recorded surface temperatures from 7680 points per second circumferentially over a 6-cm length of esophagus. Physicians were blinded to temperature data. Endoscopy was performed within 24 hours to document esophageal injury. Thermal imaging showed that most patients (10/16) experienced >=1 events where peak esophageal temperature was >40 degrees C. Three patients experienced temperatures >50 degrees C; and 1 experienced >60 degrees C. Analysis of temperature data for each subject's maximum thermal event revealed high gradients (2.3+/-1.4 degrees C/mm) and rates of change (1.5+/-1.3 degrees C/s) with an average length of esophageal involvement of 11.0+/-5.4 mm. Endoscopy identified 3 distinct thermal lesions, all in patients with temperatures >50 degrees C; all resolved within 2 weeks. CONCLUSIONS: Infrared thermography provided dynamic, high-resolution mapping of esophageal temperatures during cardiac ablation. Esophageal thermal injury occurred with temperatures >50 degrees C and was associated with large spatiotemporal gradients. Additional studies are warranted to determine the relationships between thermal parameters and esophageal injury. PMID- 29449356 TI - Meet the First Authors.

PMID- 29449366 TI - Use of Serum Transthyretin as a Prognostic Indicator and Predictor of Outcome in Cardiac Amyloid Disease Associated With Wild-Type Transthyretin. AB - BACKGROUND: Wild-type transthyretin amyloidosis (ATTRwt), an underappreciated cause of heart failure in older adults, is challenging to diagnose and monitor in the absence of validated, disease-specific biomarkers. We examined the prognostic use and survival association of serum TTR (transthyretin) concentration in ATTRwt. METHODS AND RESULTS: Patients with biopsy-proven ATTRwt were retrospectively identified. Serum TTR, cardiac biomarkers, and echocardiographic parameters were assessed at baseline and follow-up evaluations. Statistical analyses included Kaplan-Meier method, Cox proportional hazard survival models, and receiver-operating characteristic curve analysis. Median serum TTR concentration at presentation was 23 mg/dL (n=116). Multivariate predictors of shorter overall survival were decreased TTR, left ventricular ejection fraction and elevated cTn-I (cardiac troponin I); an inclusive model demonstrated superior accuracy in 4-year survival prediction by receiver-operating characteristic curve analysis (area under the curve, 0.77). TTR values lower than the normal limit, <18 mg/dL, were associated with shorter survival (2.8 versus 4.1 years; P=0.03). Further, TTR values at 1- and 2-year follow-ups were significantly lower (P<0.001) in untreated patients (n=23) compared with those treated with TTR stabilizer, diflunisal (n=12), after baseline evaluation. During 2-year follow up, unchanged TTR corresponded to increased cTn-I (P=0.006) in untreated patients; conversely, the diflunisal-treated group showed increased TTR (P=0.001) and stabilized cTn-I and left ventricular ejection fraction at 1 year. CONCLUSIONS: In this series of biopsy-proven ATTRwt, lower baseline serum TTR concentration was associated with shorter survival as an independent predictor of outcome. Longitudinal analysis demonstrated that decreasing TTR corresponded to worsening cardiac function. These data suggest that TTR may be a useful prognostic marker and predictor of outcome in ATTRwt. PMID- 29449364 TI - Diabetic Cardiomyopathy: An Update of Mechanisms Contributing to This Clinical Entity. AB - Heart failure and related morbidity and mortality are increasing at an alarming rate, in large part, because of increases in aging, obesity, and diabetes mellitus. The clinical outcomes associated with heart failure are considerably worse for patients with diabetes mellitus than for those without diabetes mellitus. In people with diabetes mellitus, the presence of myocardial dysfunction in the absence of overt clinical coronary artery disease, valvular disease, and other conventional cardiovascular risk factors, such as hypertension and dyslipidemia, has led to the descriptive terminology, diabetic cardiomyopathy. The prevalence of diabetic cardiomyopathy is increasing in parallel with the increase in diabetes mellitus. Diabetic cardiomyopathy is initially characterized by myocardial fibrosis, dysfunctional remodeling, and associated diastolic dysfunction, later by systolic dysfunction, and eventually by clinical heart failure. Impaired cardiac insulin metabolic signaling, mitochondrial dysfunction, increases in oxidative stress, reduced nitric oxide bioavailability, elevations in advanced glycation end products and collagen-based cardiomyocyte and extracellular matrix stiffness, impaired mitochondrial and cardiomyocyte calcium handling, inflammation, renin-angiotensin-aldosterone system activation, cardiac autonomic neuropathy, endoplasmic reticulum stress, microvascular dysfunction, and a myriad of cardiac metabolic abnormalities have all been implicated in the development and progression of diabetic cardiomyopathy. Molecular mechanisms linked to the underlying pathophysiological changes include abnormalities in AMP-activated protein kinase, peroxisome proliferator-activated receptors, O-linked N-acetylglucosamine, protein kinase C, microRNA, and exosome pathways. The aim of this review is to provide a contemporary view of these instigators of diabetic cardiomyopathy, as well as mechanistically based strategies for the prevention and treatment of diabetic cardiomyopathy. PMID- 29449367 TI - Load-Independent Systolic and Diastolic Right Ventricular Function in Heart Failure With Preserved Ejection Fraction as Assessed by Resting and Handgrip Exercise Pressure-Volume Loops. AB - BACKGROUND: Although systolic right ventricular (RV) dysfunction has been shown to be a potent predictor for adverse outcomes in patients with heart failure with preserved ejection fraction (HFpEF), RV functional abnormalities in the course of the syndrome are not well characterized. We, therefore, sought to assess load independent and load-dependent systolic and diastolic characteristics of RV function in stable outpatients with HFpEF. METHODS AND RESULTS: We invasively obtained RV and left ventricular pressure-volume loops in 24 HFpEF patients and 9 patients without heart failure symptoms with a conductance catheter during basal conditions and handgrip exercise. Transient preload reduction was used to extrapolate the RV end-systolic elastance and diastolic stiffness constant. HFpEF patients and controls showed similar left ventricular and RV dimensions and ejection fractions with elevated left ventricular filling pressures. In HFpEF patients, invasively determined load-independent RV contractility (P=0.04) and load-independent passive RV stiffness constant beta (P<0.01) were elevated. Although RV relaxation and cardiac output were similar at baseline, HFpEF patients demonstrated a blunted increase in cardiac output under exercise (P=0.01) associated with prolonged RV relaxation (P=0.01), decrease in stroke volume (P<0.01), higher RV-filling pressures (P<0.01), and a marked increase in the end-diastolic pressure-volume relationship (P<0.01). CONCLUSIONS: In compensated stages of the HFpEF syndrome, systolic RV function is preserved, but diastolic abnormalities with intrinsic RV stiffness and prolonged RV relaxation are already present. Impaired diastolic RV reserve contributes to a blunted increase in cardiac output during exertion. Because impairments in diastolic function seem to be a biventricular phenomenon, RV diastolic dysfunction warrants further consideration when characterizing HFpEF patients.

PMID- 29449368 TI - Immunosuppressive Therapy Improves Both Short- and Long-Term Prognosis in Patients With Virus-Negative Nonfulminant Inflammatory Cardiomyopathy. AB - BACKGROUND: Inflammatory cardiomyopathy (infl-CMP) is characterized by increased cardiac inflammation in the absence of viruses, ischemia, valvular disease, or other apparent causes. Studies addressing the efficacy of immunosuppressive therapy in patients with infl-CMP are sparse. This study retrospectively investigates whether immunosuppressive agents on top of heart failure therapy according to current guidelines improves cardiac function and long-term outcome in patients with infl-CMP. METHODS AND RESULTS: Within the Innsbruck and Maastricht Cardiomyopathy Registry, a total of 209 patients fulfilled the criteria for infl-CMP using endomyocardial biopsy (>=14 infiltrating inflammatory cells/mm2). A total of 110 (53%) patients received immunosuppressive therapy and 99 (47%) did not. To correct for potential selection bias, 1:1 propensity score matching was used on all significant baseline parameters, resulting in a total of 90 patients per group. Baseline characteristics did not significantly differ between both patient groups, reflecting optimal propensity score matching. After a median follow-up of 31 (15-47) months, immunosuppressive therapy resulted in an improved long-term outcome (eg, heart transplantation-free survival) as compared with standard heart failure therapy alone (Log-rank P=0.043; hazard ratio, 0.34 [95% CI, 0.17-0.92]) and in a significant larger increase of left ventricular ejection fraction after a mean of 12 months follow-up, as compared with patients receiving standard heart failure treatment only (12.2% versus 7.3%, respectively; P=0.036). CONCLUSIONS: To conclude, this study suggests that immunosuppressive therapy in infl-CMP patients results in an improved heart transplantation-free survival as compared with standard heart failure therapy alone, underscoring the urgent need for a large prospective multicenter trial.

PMID- 29449370 TI - Structural basis for antibody targeting of the broadly expressed microbial polysaccharide poly-N-acetylglucosamine. AB - In response to the widespread emergence of antibiotic-resistant microbes, new therapeutic agents are required for many human pathogens. A non-mammalian polysaccharide, poly-N-acetyl-d-glucosamine (PNAG), is produced by bacteria, fungi, and protozoan parasites. Antibodies that bind to PNAG and its deacetylated form (dPNAG) exhibit promising in vitro and in vivo activities against many microbes. A human IgG1 mAb (F598) that binds both PNAG and dPNAG has opsonic and protective activities against multiple microbial pathogens and is undergoing preclinical and clinical assessments as a broad-spectrum antimicrobial therapy. Here, to understand how F598 targets PNAG, we determined crystal structures of the unliganded F598 antigen-binding fragment (Fab) and its complexes with N acetyl-d-glucosamine (GlcNAc) and a PNAG oligosaccharide. We found that F598 recognizes PNAG through a large groove-shaped binding site that traverses the entire light- and heavy-chain interface and accommodates at least five GlcNAc residues. The Fab-GlcNAc complex revealed a deep binding pocket in which the monosaccharide and a core GlcNAc of the oligosaccharide were almost identically positioned, suggesting an anchored binding mechanism of PNAG by F598. The Fab used in our structural analyses retained binding to PNAG on the surface of an antibiotic-resistant, biofilm-forming strain of Staphylococcus aureus Additionally, a model of intact F598 binding to two pentasaccharide epitopes indicates that the Fab arms can span at least 40 GlcNAc residues on an extended PNAG chain. Our findings unravel the structural basis for F598 binding to PNAG on microbial surfaces and biofilms. PMID- 29449371 TI - Biochemical characterization and essentiality of Plasmodium fumarate hydratase. AB - Plasmodium falciparum (Pf), the causative agent of malaria, has an iron-sulfur cluster-containing class I fumarate hydratase (FH) that catalyzes the interconversion of fumarate to malate, a well-known reaction in the tricarboxylic acid cycle. In humans, the same reaction is catalyzed by class II FH that has no sequence or structural homology with the class I enzyme from Plasmodium Fumarate is generated in large quantities in the parasite as a by-product of AMP synthesis and is converted to malate by FH and then used in the generation of the key metabolites oxaloacetate, aspartate, and pyruvate. Previous studies have identified the FH reaction as being essential to P. falciparum, but biochemical characterization of PfFH that may provide leads for the development of specific inhibitors is lacking. Here, we report on the kinetic characterization of purified recombinant PfFH, functional complementation of fh deficiency in Escherichia coli, and mitochondrial localization in the parasite. We found that the substrate analog mercaptosuccinic acid is a potent PfFH inhibitor, with a Ki value in the nanomolar range. The fh gene could not be knocked out in Plasmodium berghei when transfectants were introduced into BALB/c mice; however, fh knockout was successful when C57BL/6 mice were used as host, suggesting that the essentiality of the fh gene to the parasite was mouse strain-dependent. PMID- 29449372 TI - Ligand-mediated protein degradation reveals functional conservation among sequence variants of the CUL4-type E3 ligase substrate receptor cereblon. AB - Upon binding to thalidomide and other immunomodulatory drugs, the E3 ligase substrate receptor cereblon (CRBN) promotes proteosomal destruction by engaging the DDB1-CUL4A-Roc1-RBX1 E3 ubiquitin ligase in human cells but not in mouse cells, suggesting that sequence variations in CRBN may cause its inactivation. Therapeutically, CRBN engagers have the potential for broad applications in cancer and immune therapy by specifically reducing protein expression through targeted ubiquitin-mediated degradation. To examine the effects of defined sequence changes on CRBN's activity, we performed a comprehensive study using complementary theoretical, biophysical, and biological assays aimed at understanding CRBN's nonprimate sequence variations. With a series of recombinant thalidomide-binding domain (TBD) proteins, we show that CRBN sequence variants retain their drug-binding properties to both classical immunomodulatory drugs and dBET1, a chemical compound and targeting ligand designed to degrade bromodomain containing 4 (BRD4) via a CRBN-dependent mechanism. We further show that dBET1 stimulates CRBN's E3 ubiquitin-conjugating function and degrades BRD4 in both mouse and human cells. This insight paves the way for studies of CRBN-dependent proteasome-targeting molecules in nonprimate models and provides a new understanding of CRBN's substrate-recruiting function. PMID- 29449373 TI - Tyrosine hydroxylase down-regulation after loss of Abelson helper integration site 1 (AHI1) promotes depression via the circadian clock pathway in mice. AB - Abelson helper integration site 1 (AHI1) is associated with several neuropsychiatric and brain developmental disorders, such as schizophrenia, depression, autism, and Joubert syndrome. Ahi1 deficiency in mice leads to behaviors typical of depression. However, the mechanisms by which AHI1 regulates behavior remain to be elucidated. Here, we found that down-regulation of expression of the rate-limiting enzyme in dopamine biosynthesis, tyrosine hydroxylase (TH), in the midbrains of Ahi1-knockout (KO) mice is responsible for Ahi1-deficiency-mediated depressive symptoms. We also found that Rev-Erbalpha, a TH transcriptional repressor and circadian regulator, is up-regulated in the Ahi1 KO mouse midbrains and Ahi1-knockdown Neuro-2a cells. Moreover, brain and muscle Arnt-like protein 1 (BMAL1), the Rev-Erbalpha transcriptional regulator, is also increased in the Ahi1-KO mouse midbrains and Ahi1-knockdown cells. Our results further revealed that AHI1 decreases BMAL1/Rev-Erbalpha expression by interacting with and repressing retinoic acid receptor-related orphan receptor alpha, a nuclear receptor and transcriptional regulator of circadian genes. Of note, Bmal1 deficiency reversed the reduction in TH expression induced by Ahi1 deficiency. Moreover, microinfusion of the Rev-Erbalpha inhibitor SR8278 into the ventral midbrain of Ahi1-KO mice significantly increased TH expression in the ventral tegmental area and improved their depressive symptoms. These findings provide a mechanistic explanation for a link between AHI1-related behaviors and the circadian clock pathway, indicating an involvement of circadian regulatory proteins in AHI1-regulated mood and behavior. PMID- 29449374 TI - Time-resolved analysis of amino acid stress identifies eIF2 phosphorylation as necessary to inhibit mTORC1 activity in liver. AB - Amino acid availability is sensed by GCN2 (general control nonderepressible 2) and mechanistic target of rapamycin complex 1 (mTORC1), but how these two sensors coordinate their respective signal transduction events remains mysterious. In this study we utilized mouse genetic models to investigate the role of GCN2 in hepatic mTORC1 regulation upon amino acid stress induced by a single injection of asparaginase. We found that deletion of Gcn2 prevented hepatic phosphorylation of eukaryotic initiation factor 2alpha to asparaginase and instead unleashed mTORC1 activity. This change in intracellular signaling occurred within minutes and resulted in increased 5'-terminal oligopyrimidine mRNA translation instead of activating transcription factor 4 synthesis. Asparaginase also promoted hepatic mRNA levels of several genes which function as mTORC1 inhibitors, and these genes were blunted or blocked in the absence of Gcn2, but their timing could not explain the early discordant effects in mTORC1 signaling. Preconditioning mice with a chemical endoplasmic reticulum stress agent before amino acid stress rescued normal mTORC1 repression in the liver of Gcn2-/- mice but not in livers with both Gcn2 and the endoplasmic reticulum stress kinase, Perk, deleted. Furthermore, treating wildtype and Gcn2-/- mice with ISRIB, an inhibitor of PERK signaling, also failed to alter hepatic mTORC1 responses to asparaginase, although administration of ISRIB alone had an inhibitory GCN2-independent effect on mTORC1 activity. Taken together, the data show that activating transcription factor 4 is not required, but eukaryotic initiation factor 2alpha phosphorylation is necessary to prevent mTORC1 activation during amino acid stress. PMID- 29449375 TI - Novosphingobium aromaticivorans uses a Nu-class glutathione S-transferase as a glutathione lyase in breaking the beta-aryl ether bond of lignin. AB - As a major component of plant cell walls, lignin is a potential renewable source of valuable chemicals. Several sphingomonad bacteria have been identified that can break the beta-aryl ether bond connecting most phenylpropanoid units of the lignin heteropolymer. Here, we tested three sphingomonads predicted to be capable of breaking the beta-aryl ether bond of the dimeric aromatic compound guaiacylglycerol-beta-guaiacyl ether (GGE) and found that Novosphingobium aromaticivorans metabolizes GGE at one of the fastest rates thus far reported. After the ether bond of racemic GGE is broken by replacement with a thioether bond involving glutathione, the glutathione moiety must be removed from the resulting two stereoisomers of the phenylpropanoid conjugate beta-glutathionyl gamma-hydroxypropiovanillone (GS-HPV). We found that the Nu-class glutathione S transferase NaGSTNu is the only enzyme needed to remove glutathione from both (R) and (S)-GS-HPV in N. aromaticivorans We solved the crystal structure of NaGSTNu and used molecular modeling to propose a mechanism for the glutathione lyase (deglutathionylation) reaction in which an enzyme-stabilized glutathione thiolate attacks the thioether bond of GS-HPV, and the reaction proceeds through an enzyme stabilized enolate intermediate. Three residues implicated in the proposed mechanism (Thr51, Tyr166, and Tyr224) were found to be critical for the lyase reaction. We also found that Nu-class GSTs from Sphingobium sp. SYK-6 (which can also break the beta-aryl ether bond) and Escherichia coli (which cannot break the beta-aryl ether bond) can also cleave (R)- and (S)-GS-HPV, suggesting that glutathione lyase activity may be common throughout this widespread but largely uncharacterized class of glutathione S-transferases. PMID- 29449377 TI - Haploid embryonic stem cells can be enriched and maintained by simple filtration. AB - Mammalian haploid embryonic stem cells (haESCs) serve as a powerful tool for genetic analyses at both the cellular and organismal levels. However, spontaneous diploidization of haESCs limits their use in these analyses. Addition of small molecules to the culture medium to control the cell cycle can slow down diploidization, but cell-sorting methods such as FACS are still required to enrich haploid cells for long-term maintenance in vitro Here, acting on our observation that haploid and diploidized cells differ in diameter, we developed a simplified filtration method to enrich haploid cells from cultured haESCs. We found that regular cell filtration with this system reliably maintained the haploidy of mouse haESCs for over 30 passages. Importantly, CRISPR/Cas9-mediated knockout and knockin were successfully achieved in the filtered cells, leading to stable haploid cell lines carrying the desired gene modifications. Of note, by injecting haESCs into metaphase II oocytes, we efficiently obtained live mice with the expected genetic traits, indicating that regular filtration maintained the functional integrity of haESCs. Moreover, this filtration system was also feasible for derivation of mouse haESCs from parthenogenetic haploid blastocysts and for human haESC maintenance. In conclusion, we have identified a reliable, efficient, and easy-to-handle technique for countering diploidization of haploid cells, a major obstacle in haESC applications. PMID- 29449376 TI - Structural basis for the glycosyltransferase activity of the Salmonella effector SseK3. AB - The Salmonella-secreted effector SseK3 translocates into host cells, targeting innate immune responses, including NF-kappaB activation. SseK3 is a glycosyltransferase that transfers an N-acetylglucosamine (GlcNAc) moiety onto the guanidino group of a target arginine, modulating host cell function. However, a lack of structural information has precluded elucidation of the molecular mechanisms in arginine and GlcNAc selection. We report here the crystal structure of SseK3 in its apo form and in complex with hydrolyzed UDP-GlcNAc. SseK3 possesses the typical glycosyltransferase type-A (GT-A)-family fold and the metal coordinating DXD motif essential for ligand binding and enzymatic activity. Several conserved residues were essential for arginine GlcNAcylation and SseK3 mediated inhibition of NF-kappaB activation. Isothermal titration calorimetry revealed SseK3's preference for manganese coordination. The pattern of interactions in the substrate-bound SseK3 structure explained the selection of the primary ligand. Structural rearrangement of the C-terminal residues upon ligand binding was crucial for SseK3's catalytic activity, and NMR analysis indicated that SseK3 has limited UDP-GlcNAc hydrolysis activity. The release of free N-acetyl alpha-d-glucosamine, and the presence of the same molecule in the SseK3 active site, classified it as a retaining glycosyltransferase. A glutamate residue in the active site suggested a double-inversion mechanism for the arginine N-glycosylation reaction. Homology models of SseK1, SseK2, and the Escherichia coli orthologue NleB1 reveal differences in the surface electrostatic charge distribution, possibly accounting for their diverse activities. This first structure of a retaining GT-A arginine N-glycosyltransferase provides an important step toward a better understanding of this enzyme class and their roles as bacterial effectors.

AB - Transcription factors (TFs) exert their regulatory influence through the binding of enhancers, resulting in coordination of gene expression programs. Active enhancers are often characterized by the presence of short, unstable transcripts termed enhancer RNAs (eRNAs). While their function remains unclear, we demonstrate that eRNAs are a powerful readout of TF activity. We infer sites of eRNA origination across hundreds of publicly available nascent transcription data sets and show that eRNAs initiate from sites of TF binding. By quantifying the colocalization of TF binding motif instances and eRNA origins, we derive a simple statistic capable of inferring TF activity. In doing so, we uncover dozens of previously unexplored links between diverse stimuli and the TFs they affect. PMID- 29449409 TI - A human-specific switch of alternatively spliced AFMID isoforms contributes to TP53 mutations and tumor recurrence in hepatocellular carcinoma. AB - Pre-mRNA splicing can contribute to the switch of cell identity that occurs in carcinogenesis. Here, we analyze a large collection of RNA-seq data sets and report that splicing changes in hepatocyte-specific enzymes, such as AFMID and KHK, are associated with HCC patients' survival and relapse. The switch of AFMID isoforms is an early event in HCC development and is associated with driver mutations in TP53 and ARID1A The switch of AFMID isoforms is human-specific and not detectable in other species, including primates. Finally, we show that overexpression of the full-length AFMID isoform leads to a higher NAD+ level, lower DNA-damage response, and slower cell growth in HepG2 cells. The integrative analysis uncovered a mechanistic link between splicing switches, de novo NAD+ biosynthesis, driver mutations, and HCC recurrence. PMID- 29449410 TI - Conserved microRNA targeting reveals preexisting gene dosage sensitivities that shaped amniote sex chromosome evolution. AB - Mammalian X and Y Chromosomes evolved from an ordinary autosomal pair. Genetic decay of the Y led to X Chromosome inactivation (XCI) in females, but some Y linked genes were retained during the course of sex chromosome evolution, and many X-linked genes did not become subject to XCI. We reconstructed gene-by-gene dosage sensitivities on the ancestral autosomes through phylogenetic analysis of microRNA (miRNA) target sites and compared these preexisting characteristics to the current status of Y-linked and X-linked genes in mammals. Preexisting heterogeneities in dosage sensitivity, manifesting as differences in the extent of miRNA-mediated repression, predicted either the retention of a Y homolog or the acquisition of XCI following Y gene decay. Analogous heterogeneities among avian Z-linked genes predicted either the retention of a W homolog or gene specific dosage compensation following W gene decay. Genome-wide analyses of human copy number variation indicate that these heterogeneities consisted of sensitivity to both increases and decreases in dosage. We propose a model of XY/ZW evolution incorporating such preexisting dosage sensitivities in determining the evolutionary fates of individual genes. Our findings thus provide a more complete view of the role of dosage sensitivity in shaping the mammalian and avian sex chromosomes and reveal an important role for post-transcriptional regulatory sequences (miRNA target sites) in sex chromosome evolution. PMID- 29449412 TI - Hemodynamic Characteristics in Significant Symptomatic and Asymptomatic Primary Mitral Valve Regurgitation at Rest and During Exercise. AB - BACKGROUND: In severe asymptomatic primary mitral valve regurgitation without risk factors, surgery strategy is controversial. We sought to clarify whether being symptomatic corresponds to the hemodynamic burden and reduced exercise capacity. A better understanding of this may contribute to optimize timing of surgery. METHODS AND RESULTS: Subjects with asymptomatic (New York Heart Association functional class I, n=29) or symptomatic (New York Heart Association functional class II and III, n=28) significant primary mitral valve regurgitation (effective regurgitant orifice, >=0.30 cm2; left ventricular ejection fraction, >60%) were included. Right heart catheterization during rest and exercise, echocardiography, magnetic resonance imaging, and peak oxygen consumption test was performed. Symptomatic subjects had significantly higher pulmonary capillary wedge pressure at rest (14+/-4 versus 11+/-3 mm Hg; P=0.003) and at maximal exercise (30+/-6 versus 25+/-7 mm Hg; P=0.02) and higher mean pulmonary artery pressure (PAP) at rest (22+/-7 versus 18+/-4 mm Hg; P=0.005) and maximal exercise (46+/-8 versus 39+/-7 mm Hg; P=0.005) than asymptomatic subjects. Among asymptomatic subjects with normal resting value, exercise testing revealed a systolic PAP >60 mm Hg in 34%. Also the reverse response with minimal increase in pulmonary capillary wedge pressure and mean PAP during exercise was seen, especially in asymptomatic subjects. Among symptomatic subjects, we found a significant inverse correlation between resting mean PAP and left ventricular ejection fraction (r=-0.52; P=0.02) and right ventricular ejection fraction (r= 0.67; P<0.01). Peak oxygen consumption was equal and normal in both groups and correlated with left ventricular stroke volume but not with pulmonary capillary wedge pressure. CONCLUSIONS: Symptoms in patients with severe mitral valve regurgitation relate to congestion (pulmonary capillary wedge pressure and PAP), but not to peak oxygen consumption, which is determined by forward left ventricular stroke volume. Exercise testing reveals a higher mitral valve regurgitation burden in apparently asymptomatic patients. CLINICAL TRIAL REGISTRATION: URL: http://www.clinicaltrials.gov. Unique identifier: NCT02961647. PMID- 29449411 TI - Molecular Imaging in Drug Discovery and Development. AB - Noninvasive imaging has played an increasing role in the process of cardiovascular drug development. This review focuses specifically on the use of molecular imaging, which has been increasingly applied to improve and accelerate certain preclinical steps in drug development, including the identification of appropriate therapeutic targets, evaluation of on-target and off-target effects of candidate therapies, assessment of dose response, and the evaluation of drug or biological biodistribution and pharmacodynamics. Unlike the case in cancer medicine, in cardiovascular medicine, molecular imaging has not been used as a primary surrogate clinical end point for drug approval. However, molecular imaging has been applied in early clinical trials, particularly in phase 0 studies, to demonstrate proof-of-concept or to explain variation in treatment effect. Many of these applications where molecular imaging has been used in drug development have involved the retasking of technologies that were originally intended as clinical diagnostics. With greater experience and recognition of the rich information provided by in vivo molecular imaging, it is anticipated that it will increasingly be used to address the enormous time and costs associated with bringing a new drug to clinical launch.

AB - Magnesium is the second most abundant intracellular cation. Deficiency can cause several neurological complications, including cerebellar syndromes, with various MRI findings. These include cerebellar oedema, presumably through a similar mechanism to that in posterior reversible encephalopathy syndrome (PRES). People particularly vulnerable to deficiency include those with high alcohol consumption, excessive loss due to gastrointestinal pathology and those taking certain medications, including proton pump inhibitors. We report three patients with cerebellar syndromes associated with hypomagnesaemia. These cases support the previously reported association between hypomagnesaemia and reversible cerebellar dysfunction and illustrate the range of potential presentations. They highlight an uncommon but treatable cause of cerebellar ataxia that may present to acute neurological liaison services. PMID- 29449414 TI - Pathogen Trojan Horse Delivers Bioactive Host Protein to Alter Maize Anther Cell Behavior in Situ. AB - Small proteins are crucial signals during development, host defense, and physiology. The highly spatiotemporal restricted functions of signaling proteins remain challenging to study in planta. The several month span required to assess transgene expression, particularly in flowers, combined with the uncertainties from transgene position effects and ubiquitous or overexpression, makes monitoring of spatiotemporally restricted signaling proteins lengthy and difficult. This situation could be rectified with a transient assay in which protein deployment is tightly controlled spatially and temporally in planta to assess protein functions, timing, and cellular targets as well as to facilitate rapid mutagenesis to define functional protein domains. In maize (Zea mays), secreted ZmMAC1 (MULTIPLE ARCHESPORIAL CELLS1) was proposed to trigger somatic niche formation during anther development by participating in a ligand-receptor module. Inspired by Homer's Trojan horse myth, we engineered a protein delivery system that exploits the secretory capabilities of the maize smut fungus Ustilago maydis, to allow protein delivery to individual cells in certain cell layers at precise time points. Pathogen-supplied ZmMAC1 cell-autonomously corrected both somatic cell division and differentiation defects in mutant Zmmac1-1 anthers. These results suggest that exploiting host-pathogen interactions may become a generally useful method for targeting host proteins to cell and tissue types to clarify cellular autonomy and to analyze steps in cell responses. PMID- 29449420 TI - Childhood Stature and Growth in Relation to First Ischemic Stroke or Intracerebral Hemorrhage. AB - BACKGROUND AND PURPOSE: Attained height, an indicator of genetic potential and childhood growth environment, is inversely associated with stroke, but the mechanisms are poorly understood. We investigated whether childhood height and growth are associated with ischemic stroke (IS) and intracerebral hemorrhage (ICH). METHODS: In a cohort of Danish schoolchildren born 1930 to 1989, with measured height from 7 to 13 years, we investigated associations of childhood stature and growth with risks of adult IS and ICH. Cox proportional hazards regressions were performed to estimate hazard ratios (HRs) with CIs separately for women and men. RESULTS: Among 311 009 individuals, 10 412 were diagnosed with IS and 2546 with ICH. Height at 7 years was inversely and significantly associated with IS in both sexes (per z score, equivalent to ~5.2 cm in women and 5.1 cm in men; women: HR=0.89 [95% CI: 0.87-0.92]; men: HR=0.90 [95% CI: 0.88 0.92]) and with ICH in men (HR=0.89 [95% CI: 0.84-0.94]) but not in women (HR=0.97 [95% CI: 0.91-1.04]). Associations were similar at older childhood ages and were stable throughout the study period. No statistically significant associations for growth from 7 to 13 years were observed for IS or ICH. CONCLUSIONS: Short stature at 7 to 13 years is significantly associated with increased risks of IS in both sexes and with ICH in men. Growth during this period of childhood is not significantly associated with either of these stroke subtypes, suggesting that underlying mechanisms linking height with risks of stroke may exert their influence already by early childhood. PMID- 29449421 TI - Increased T-helper 17.1 cells in sarcoidosis mediastinal lymph nodes. AB - The lung-draining mediastinal lymph nodes (MLNs) are currently widely used to diagnose sarcoidosis. We previously reported that T-helper (Th) 17.1 cells are responsible for the exaggerated interferon-gamma production in sarcoidosis lungs. In this study, we aimed to investigate 1) whether Th17.1 cells are also increased in the MLNs of sarcoidosis patients and 2) whether frequencies of the Th17.1 cells at diagnosis may correlate with disease progression.MLN cells from treatment-naive pulmonary sarcoidosis patients (n=17) and healthy controls (n=22) and peripheral blood mononuclear cells (n=34) and bronchoalveolar lavage fluid (BALF) (n=36) from sarcoidosis patients were examined for CD4+ T-cell subset proportions using flow cytometry.Higher proportions of Th17.1 cells were detected in sarcoidosis MLNs than in control MLNs. Higher Th17.1 cell proportions were found in sarcoidosis BALF compared with MLNs and peripheral blood. Furthermore, BALF Th17.1 cell proportions were significantly higher in patients developing chronic disease than in patients undergoing resolution within 2 years of clinical follow-up.These data suggest that Th17.1 cell proportions in pulmonary sarcoidosis can be evaluated as a diagnostic and/or prognostic marker in clinical practice and could serve as a new therapeutic target.

PMID- 29449425 TI - Young and middle-aged adults with airflow limitation according to lower limit of normal but not fixed ratio have high morbidity and poor survival: a population based prospective cohort study. AB - A presumed consequence of using a fixed ratio for the definition of airflow limitation (AFL) has been overdiagnosis among older individuals and underdiagnosis among younger individuals. However, the prognosis of younger individuals with potentially underdiagnosed AFL is poorly described. We hypothesised that potential underdiagnosis of AFL at a younger age is associated with poor prognosis.We assigned 95 288 participants aged 20-100 years from the Copenhagen General Population Study into the following groups: individuals without AFL with forced expiratory volume in 1 s (FEV1)/forced vital capacity (FVC) >=0.70 and >=lower limit of normal (LLN) (n=78 779, 83%); individuals with potentially underdiagnosed AFL with FEV1/FVC >=0.70 and =LLN (n=3088, 3%); and individuals with AFL with FEV1/FVC <0.70 and 10 years without progression from initial diagnosis). All three entities were indistinguishable at the genomic level exhibiting low genomic complexity and similar types of somatic mutations. Exonic mutations were not frequently identified in putative chronic lymphocytic leukemia driver genes in all settings, including low-count monoclonal B-cell lymphocytosis. To corroborate these findings, we also performed deep sequencing in 11 known frequently mutated genes in an extended cohort of 28 monoclonal B-cell lymphocytosis/chronic lymphocytic leukemia cases. Interestingly, shared mutations were detected between clonal B cells and paired polymorphonuclear cells, strengthening the notion that at least a fraction of somatic mutations may occur before disease onset, likely at the hematopoietic stem cell level. Finally, we identified previously unreported non coding variants targeting pathways relevant to B-cell and chronic lymphocytic leukemia development, likely associated with the acquisition of the characteristic neoplastic phenotype typical of both monoclonal B-cell lymphocytosis and chronic lymphocytic leukemia.

AB - Survival of children with relapsed acute lymphoblastic leukemia is poor, and understanding mechanisms underlying resistance is essential to developing new therapy. Relapse-specific heterozygous deletions in MSH6, a crucial part of DNA mismatch repair, are frequently detected. Our aim was to determine whether MSH6 deletion results in a hypermutator phenotype associated with generation of secondary mutations involved in drug resistance, or if it leads to a failure to initiate apoptosis directly in response to chemotherapeutic agents. We knocked down MSH6 in mismatch repair proficient cell lines (697 and UOCB1) and showed significant increases in IC50s to 6-thioguanine and 6-mercaptopurine (697: 26- and 9-fold; UOCB1: 5- and 8-fold) in vitro, as well as increased resistance to 6 mercaptopurine treatment in vivo No shift in IC50 was observed in deficient cells (Reh and RS4;11). 697 MSH6 knockdown resulted in increased DNA thioguanine nucleotide levels compared to non-targeted cells (3070 vs 1722 fmol/MUg DNA) with no difference observed in mismatch repair deficient cells. Loss of MSH6 did not give rise to microsatellite instability in cell lines or clinical samples, nor did it significantly increase mutation rate, but rather resulted in a defect in cell cycle arrest upon thiopurine exposure. MSH6 knockdown cells showed minimal activation of checkpoint regulator CHK1, gammaH2AX (DNA damage marker) and p53 levels upon treatment with thiopurines, consistent with intrinsic chemoresistance due to failure to recognize thioguanine nucleotide mismatching and initiate mismatch repair. Aberrant MSH6 adds to the list of alterations/mutations associated with acquired resistance to purine analogs emphasizing the importance of thiopurine therapy.

AB - A subset of hematologic cancer patients is refractory to treatment or suffers relapse, due in part to minimal residual disease, whereby some cancer cells survive treatment. Cell-adhesion-mediated drug resistance is an important mechanism, whereby cancer cells receive survival signals via interaction with e.g. stromal cells. No genome-wide studies of in vitro systems have yet been performed to compare gene expression in different cell subsets within a co culture and cells grown separately. Using RNA sequencing and species-specific read mapping, we compared transcript levels in human Jeko-1 mantle cell lymphoma cells stably adhered to mouse MS-5 stromal cells or in suspension within a co culture or cultured separately as well as in stromal cells in co-culture or in separate culture. From 1050 differentially expressed transcripts in adherent mantle cell lymphoma cells, we identified 24 functional categories that together represent four main functional themes, anti-apoptosis, B-cell signaling, cell adhesion/migration and early mitosis. A comparison with previous mantle cell lymphoma and chronic lymphocytic leukemia studies, of gene expression differences between lymph node and blood, identified 116 genes that are differentially expressed in all three studies. From these genes, we suggest a core set of genes (CCL3, CCL4, DUSP4, ETV5, ICAM1, IL15RA, IL21R, IL4I1, MFSD2A, NFKB1, NFKBIE, SEMA7A, TMEM2) characteristic of cells undergoing cell-adhesion-mediated microenvironment signaling in mantle cell lymphoma/chronic lymphocytic leukemia. The model system developed and characterized here together with the core gene set will be useful for future studies of pathways that mediate increased cancer cell survival and drug resistance mechanisms.

PMID- 29449437 TI - Dynamic clonal progression in xenografts of acute lymphoblastic leukemia with intrachromosomal amplification of chromosome 21. AB - Intrachromosomal amplification of chromosome 21 is a heterogeneous chromosomal rearrangement occurring in 2% of cases of childhood precursor B-cell acute lymphoblastic leukemia. These abnormalities are too complex to engineer faithfully in animal models and are unrepresented in leukemia cell lines. As a resource for future functional and preclinical studies, we have created xenografts from the leukemic blasts of patients with intrachromosomal amplification of chromosome 21 and characterized them by in-vivo and ex-vivo luminescent imaging, flow immunophenotyping, and histological and ultrastructural analyses of bone marrow and the central nervous system. Investigation of up to three generations of xenografts revealed phenotypic evolution, branching genomic architecture and, compared with other B-cell acute lymphoblastic leukemia genetic subtypes, greater clonal diversity of leukemia-initiating cells. In support of intrachromosomal amplification of chromosome 21 as a primary genetic abnormality, it was always retained through generations of xenografts, although we also observed the first example of structural evolution of this rearrangement. Clonal segregation in xenografts revealed convergent evolution of different secondary genomic abnormalities implicating several known tumor suppressor genes and a region, containing the B-cell adaptor, PIK3AP1, and nuclear receptor co repressor, LCOR, in the progression of B-cell acute lymphoblastic leukemia. Tracking of mutations in patients and derived xenografts provided evidence for co operation between abnormalities activating the RAS pathway in B-cell acute lymphoblastic leukemia and for their aggressive clonal expansion in the xeno environment. Bi-allelic loss of the CDKN2A/B locus was recurrently maintained or emergent in xenografts and also strongly selected as RNA sequencing demonstrated a complete absence of reads for genes associated with the deletions. PMID- 29449440 TI - Lung clearance index to monitor treatment response in pulmonary exacerbations in preschool children with cystic fibrosis. AB - BACKGROUND: Antibiotic treatment for pulmonary symptoms in preschool children with cystic fibrosis (CF) varies among clinicians. The lung clearance index (LCI) is sensitive to early CF lung disease, but its utility to monitor pulmonary exacerbations in young children has not been assessed. OBJECTIVE: We aim to (1) understand how LCI changes during lower respiratory tract symptoms relative to a recent clinically stable measurement, (2) determine whether LCI can identify antibiotic treatment response and (3) compare LCI changes to changes in spirometric indices. METHODS: LCI and spirometry were measured at quarterly clinic visits over a 12-month period in preschool children with CF. Symptomatic visits were identified and classified as treated or untreated. Treatment response was estimated using propensity score matching methods. RESULTS: 104 symptomatic visits were identified in 78 participants. LCI increased from baseline in both treated (mean relative change +23.8% (95% CI 16.2 to 31.4)) and untreated symptomatic visits (mean relative change +11.2% (95% CI 2.4 to 19.9)). A significant antibiotic treatment effect was observed when LCI was used as the outcome measure (average treatment effect -15.5% (95% CI -25.4 to -5.6)) but not for z-score FEV1. CONCLUSION: LCI significantly deteriorated with pulmonary symptoms relative to baseline and improved with antibiotic treatment. These data suggest that LCI may have a role in the routine clinical care of preschool children with CF.

AB - This study explored oxidative stress, nicotinamide adenine dinucleotide phosphate oxidase-2 (Nox2) activity and endothelial function in children exposed or not to passive smoking. Compared with controls (n=57), Nox2 activity and isoprostanes were higher in children exposed to passive smoking (n=57); conversely, nitric oxide (NO) bioavailability and flow-mediated dilation were lower in children exposed to passive smoking. A bivariate analysis showed that Nox2 activity correlated with flow-mediated dilation, NO bioavailability and isoprostanes. A multivariate analysis showed that Nox2 activity was significantly associated with serum isoprostanes and cotinine levels; flow-mediated dilation was associated with isoprostanes and carotid intima-media thickness.In children exposed to passive smoking, Nox2-derived oxidative stress is upregulated and inversely associated with impaired artery dilation.

AB - BACKGROUND: Investigation of anginal chest pain has traditionally involved either assessment of the coronary anatomy by angiography or noninvasive testing for reversible ischemia. Invasive pressure wire assessment at the time of angiography offers information on both anatomy and physiology. Fractional flow reserve-guided percutaneous coronary intervention is associated with lower resource utilization and improved clinical outcome compared with angiographic guidance alone. However, the value of routine fractional flow reserve of all major coronary vessels at the time of diagnostic angiography has not been established in a randomized trial despite persuasive observational data. A change in practice to routine fractional flow reserve assessment of all major vessels during diagnostic angiography would require evidence not just of clinical benefit but also of cost effectiveness. This randomized trial aims to test that strategy. METHODS AND RESULTS: RIPCORD 2 (Does Routine Pressure Wire Assessment Influence Management Strategy at Coronary Angiography for Diagnosis of Chest Pain?) is an 1100 patient prospective, multicenter, randomized trial. Participants are randomized, after initial coronary angiography, and in equal proportion, to assessment and management according to (1) conventional angiography only or (2) additional routine pressure wire assessment in all epicardial vessels of sufficient size to be amenable to revascularization. The primary economic outcome measure will be a comparison of healthcare costs at 1 year. The primary quality-of-life outcome measure analysis will compare patient-reported quality-of-life scores at 1 year. Secondary outcome measures include clinical events at 1 year, management strategy (optimal medical therapy with or without revascularization), and angina status at 1 year according to Canadian Cardiovascular Society angina grade. CONCLUSIONS: The aim of the RIPCORD 2 trial is to assess whether a strategy of routine fractional flow reserve-guided assessment and management of all major coronary arteries will be associated with more effective resource utilization, improved quality of life, and better clinical outcome, compared with angiographic guidance alone.

AB - Evolving knowledge of sex-specific presentations, improved recognition of conventional and novel risk factors, and expanded understanding of the sex specific pathophysiology of ischemic heart disease have resulted in improved clinical outcomes in women. Yet, ischemic heart disease continues to be the leading cause of morbidity and mortality in women in the United States. The important publication by the Institute of Medicine titled "Women's Health Research-Progress, Pitfalls, and Promise," highlights the persistent disparities in cardiovascular disease burden among subgroups of women, particularly women who are socially disadvantaged because of race, ethnicity, income level, and educational attainment. These important health disparities reflect underrepresentation of women in research, with the resultant unfavorable impact on diagnosis, prevention, and treatment strategies in women at risk for cardiovascular disease. Causes of disparities are multifactorial and related to differences in risk factor prevalence, access to care, use of evidence-based guidelines, and social and environmental factors. Lack of awareness in both the public and medical community, as well as existing knowledge gap regarding sex specific differences in presentation, risk factors, pathophysiology, and response to treatment for ischemic heart disease, further contribute to outcome disparities. There is a critical need for implementation of sex- and gender specific strategies to improve cardiovascular outcomes. This review is tailored to meet the needs of a busy clinician and summarizes the contemporary trends, characterizes current sex-specific outcome disparities, delineates challenges, and proposes transformative solutions for improvement of the full spectrum of ischemic heart disease clinical care and research in women.

PMID- 29449445 TI - Evaluation of Penalized-Likelihood Estimation Reconstruction on a Digital Time-of Flight PET/CT Scanner for 18F-FDG Whole-Body Examinations. AB - The resolution and quantitative accuracy of PET are highly influenced by the reconstruction method. Penalized-likelihood estimation algorithms allow for fully convergent iterative reconstruction, generating a higher image contrast than ordered-subsets expectation maximization (OSEM) while limiting noise. In this study, a type of penalized reconstruction known as block-sequential regularized expectation maximization (BSREM) was compared with time-of-flight OSEM (TOF OSEM). Various strengths of noise penalization factor beta were tested along with various acquisition durations and transaxial fields of view (FOVs) with the aim of evaluating the performance and clinical use of BSREM for 18F-FDG PET/CT, both quantitatively and in a qualitative visual evaluation. Methods: Eleven clinical whole-body 18F-FDG PET/CT examinations acquired on a digital TOF PET/CT scanner were included. The data were reconstructed using BSREM with point-spread function recovery and beta-factors of 133, 267, 400, and 533-and using TOF OSEM with point spread function-for various acquisition times per bed position and various FOVs. Noise level, signal-to-noise ratio (SNR), signal-to-background ratio (SBR), and SUV were analyzed. A masked evaluation of visual image quality, rating several aspects, was performed by 2 nuclear medicine physicians to complement the analysis. Results: The lowest levels of noise were reached with the highest beta factor, resulting in the highest SNR, which in turn resulted in the lowest SBR. A beta-factor of 400 gave noise equivalent to TOF OSEM but produced a significant increase in SUVmax (11%), SNR (22%), and SBR (12%). BSREM with a beta-factor of 533 at a decreased acquisition duration (2 min/bed position) was comparable to TOF OSEM at a full acquisition duration (3 min/bed position). Reconstructed FOV had an impact on BSREM outcome measures; SNR increased and SBR decreased when FOV was shifted from 70 to 50 cm. The evaluation of visual image quality resulted in similar scores for reconstructions, although a beta-factor of 400 obtained the highest mean whereas a beta-factor of 267 was ranked best in overall image quality, contrast, sharpness, and tumor detectability. Conclusion: In comparison with TOF OSEM, penalized BSREM reconstruction resulted in an increased tumor SUVmax and an improved SNR and SBR at a matched level of noise. BSREM allowed for a shorter acquisition than TOF OSEM, with equal image quality. PMID- 29449446 TI - Improving the Accuracy of Simultaneously Reconstructed Activity and Attenuation Maps Using Deep Learning. AB - Simultaneous reconstruction of activity and attenuation using the maximum likelihood reconstruction of activity and attenuation (MLAA) augmented by time-of flight information is a promising method for PET attenuation correction. However, it still suffers from several problems, including crosstalk artifacts, slow convergence speed, and noisy attenuation maps (MU-maps). In this work, we developed deep convolutional neural networks (CNNs) to overcome these MLAA limitations, and we verified their feasibility using a clinical brain PET dataset. Methods: We applied the proposed method to one of the most challenging PET cases for simultaneous image reconstruction (18F-fluorinated-N-3-fluoropropyl 2-beta-carboxymethoxy-3-beta-(4-iodophenyl)nortropane [18F-FP-CIT] PET scans with highly specific binding to striatum of the brain). Three different CNN architectures (convolutional autoencoder [CAE], Unet, and Hybrid of CAE) were designed and trained to learn a CT-derived MU-map (MU-CT) from the MLAA-generated activity distribution and MU-map (MU-MLAA). The PET/CT data of 40 patients with suspected Parkinson disease were used for 5-fold cross-validation. For the training of CNNs, 800,000 transverse PET and CT slices augmented from 32 patient datasets were used. The similarity to MU-CT of the CNN-generated MU-maps (MU-CAE, MU-Unet, and MU-Hybrid) and MU-MLAA was compared using Dice similarity coefficients. In addition, we compared the activity concentration of specific (striatum) and nonspecific (cerebellum and occipital cortex) binding regions and the binding ratios in the striatum in the PET activity images reconstructed using those MU-maps. Results: The CNNs generated less noisy and more uniform MU-maps than the original MU-MLAA. Moreover, the air cavities and bones were better resolved in the proposed CNN outputs. In addition, the proposed deep learning approach was useful for mitigating the crosstalk problem in the MLAA reconstruction. The Hybrid network of CAE and Unet yielded the most similar MU maps to MU-CT (Dice similarity coefficient in the whole head = 0.79 in the bone and 0.72 in air cavities), resulting in only about a 5% error in activity and binding ratio quantification. Conclusion: The proposed deep learning approach is promising for accurate attenuation correction of activity distribution in time-of flight PET systems. PMID- 29449447 TI - Tracers for Fluorescence-Guided Surgery: How Elongation of the Polymethine Chain in Cyanine Dyes Alters the Pharmacokinetics of a Dual-Modality c[RGDyK] Tracer. AB - The potential of receptor-mediated fluorescence-based image-guided surgery tracers is generally linked to the near-infrared emission profile and good manufacturing-production availability of fluorescent dyes. Surprisingly, little is known about the critical interaction between the structural composition of the dyes and the pharmacokinetics of the tracers. In this study, a dual-modality tracer design was used to systematically and quantitatively evaluate the influence of elongation of the polymethine chain in a fluorescent cyanine dye on the imaging potential of a targeted tracer. Methods: As a model system, the integrin marker alphavbeta3 was targeted using arginylglycylaspartisc acid [RGD] based vectors functionalized with a 111In-diethylenetriaminepentaacetic acid (DTPA) chelate and a fluorescent dye: (Cy3-(SO3)methyl-COOH [emission wavelength (lambdaem), 580 nm], Cy5-(SO3)methyl-COOH [lambdaem, 680 nm], or Cy7-(SO3)methyl COOH [lambdaem, 780 nm]). Tracers were analyzed for differences in photophysical properties, serum protein binding, chemical or optical stability, and signal penetration through tissue. Receptor affinities were evaluated using saturation and competition experiments. In vivo biodistribution (SPECT imaging and percentage injected dose per gram of tissue) was assessed in tumor-bearing mice and complemented with in vivo and ex vivo fluorescence images obtained using a clinical-grade multispectral fluorescence laparoscope. Results: Two carbon-atom step variations in the polymethine chain of the fluorescent cyanine dyes were shown to significantly influence the chemical and photophysical characteristics (e.g., stability, brightness, and tissue penetration) of the hybrid RGD tracers. DTPA-Cy5-(SO3)methyl-COOH-c[RGDyK] structurally outperformed its Cy3 and Cy7 derivatives. Radioactivity-based evaluation of in vivo tracer pharmacokinetics yielded the lowest nonspecific uptake and highest tumor-to-background ratio for DTPA-Cy5-(SO3)methyl-COOH-c[RGDyK] (13.2 +/- 1.7), with the Cy3 and Cy7 analogs trailing at respective tumor-to-background ratios of 5.7 +/- 0.7 and 4.7 +/- 0.7. Fluorescence-based assessment of tumor visibility revealed a similar trend. Conclusion: These findings underline that variations in the polymethine chain lengths of cyanine dyes have a profound influence on the photophysical properties, stability, and in vivo targeting capabilities of fluorescent imaging tracers. In a direct comparison, the intermediate-length dye (Cy5) yielded a superior c[RGDyK] tracer, compared with the shorter (Cy3) and longer (Cy7) analogs.

PMID- 29449449 TI - Conserved and Divergent Features of Mesenchymal Progenitor Cell Types within the Cortical Nephrogenic Niche of the Human and Mouse Kidney. AB - Cellular interactions among nephron, interstitial, and collecting duct progenitors drive mammalian kidney development. In mice, Six2+ nephron progenitor cells (NPCs) and Foxd1+ interstitial progenitor cells (IPCs) form largely distinct lineage compartments at the onset of metanephric kidney development. Here, we used the method for analyzing RNA following intracellular sorting (MARIS) approach, single-cell transcriptional profiling, in situ hybridization, and immunolabeling to characterize the presumptive NPC and IPC compartments of the developing human kidney. As in mice, each progenitor population adopts a stereotypical arrangement in the human nephron-forming niche: NPCs capped outgrowing ureteric branch tips, whereas IPCs were sandwiched between the NPCs and the renal capsule. Unlike mouse NPCs, human NPCs displayed a transcriptional profile that overlapped substantially with the IPC transcriptional profile, and key IPC determinants, including FOXD1, were readily detected within SIX2+ NPCs. Comparative gene expression profiling in human and mouse Six2/SIX2+ NPCs showed broad agreement between the species but also identified species-biased expression of some genes. Notably, some human NPC-enriched genes, including DAPL1 and COL9A2, are linked to human renal disease. We further explored the cellular diversity of mesenchymal cell types in the human nephrogenic niche through single cell transcriptional profiling. Data analysis stratified NPCs into two main subpopulations and identified a third group of differentiating cells. These findings were confirmed by section in situ hybridization with novel human NPC markers predicted through the single-cell studies. This study provides a benchmark for the mesenchymal progenitors in the human nephrogenic niche and highlights species-variability in kidney developmental programs. PMID- 29449451 TI - Conserved and Divergent Molecular and Anatomic Features of Human and Mouse Nephron Patterning. AB - The nephron is the functional unit of the kidney, but the mechanism of nephron formation during human development is unclear. We conducted a detailed analysis of nephron development in humans and mice by immunolabeling, and we compared human and mouse nephron patterning to describe conserved and divergent features. We created protein localization maps that highlight the emerging patterns along the proximal-distal axis of the developing nephron and benchmark expectations for localization of functionally important transcription factors, which revealed unanticipated cellular diversity. Moreover, we identified a novel nephron subdomain marked by Wnt4 expression that we fate-mapped to the proximal mature nephron. Significant conservation was observed between human and mouse patterning. We also determined the time at which markers for mature nephron cell types first emerge-critical data for the renal organoid field. These findings have conceptual implications for the evolutionary processes driving the diversity of mammalian organ systems. Furthermore, these findings provide practical insights beyond those gained with mouse and rat models that will guide in vitro efforts to harness the developmental programs necessary to build human kidney structures. PMID- 29449452 TI - Evolution and Kidney Development: A Rosetta Stone for Nephrology. PMID- 29449453 TI - Conserved and Divergent Features of Human and Mouse Kidney Organogenesis. AB - Human kidney function is underpinned by approximately 1,000,000 nephrons, although the number varies substantially, and low nephron number is linked to disease. Human kidney development initiates around 4 weeks of gestation and ends around 34-37 weeks of gestation. Over this period, a reiterative inductive process establishes the nephron complement. Studies have provided insightful anatomic descriptions of human kidney development, but the limited histologic views are not readily accessible to a broad audience. In this first paper in a series providing comprehensive insight into human kidney formation, we examined human kidney development in 135 anonymously donated human kidney specimens. We documented kidney development at a macroscopic and cellular level through histologic analysis, RNA in situ hybridization, immunofluorescence studies, and transcriptional profiling, contrasting human development (4-23 weeks) with mouse development at selected stages (embryonic day 15.5 and postnatal day 2). The high resolution histologic interactive atlas of human kidney organogenesis generated can be viewed at the GUDMAP database (www.gudmap.org) together with three dimensional reconstructions of key components of the data herein. At the anatomic level, human and mouse kidney development differ in timing, scale, and global features such as lobe formation and progenitor niche organization. The data also highlight differences in molecular and cellular features, including the expression and cellular distribution of anchor gene markers used to identify key cell types in mouse kidney studies. These data will facilitate and inform in vitro efforts to generate human kidney structures and comparative functional analyses across mammalian species. PMID- 29449454 TI - Deleting HDAC3 rescues long-term memory impairments induced by disruption of the neuron-specific chromatin remodeling subunit BAF53b. AB - Multiple epigenetic mechanisms, including histone acetylation and nucleosome remodeling, are known to be involved in long-term memory formation. Enhancing histone acetylation by deleting histone deacetylases, like HDAC3, typically enhances long-term memory formation. In contrast, disrupting nucleosome remodeling by blocking the neuron-specific chromatin remodeling subunit BAF53b impairs long-term memory. Here, we show that deleting HDAC3 can ameliorate the impairments in both long-term memory and synaptic plasticity caused by BAF53b mutation. This suggests a dynamic interplay exists between histone acetylation/deacetylation and nucleosome remodeling mechanisms in the regulation of memory formation. PMID- 29449455 TI - The beneficial effect of prior experience on the acquisition of spatial memory in rats with CA1, but not large hippocampal lesions: a possible role for schema formation. AB - Prior experience has been shown to improve learning in both humans and animals, but it is unclear what aspects of recent experience are necessary to produce beneficial effects. Here, we examined the capacity of rats with complete hippocampal lesions, restricted CA1 lesions, or sham surgeries to benefit from prior experience. Animals were tested in two different spatial tasks in the watermaze, the conventional watermaze task and delayed match-to-position. The two lesions impaired performance in both tasks when rats had no prior experience. However, when given prior training with one task, CA1 lesions had no effect on performance in the other task. In contrast, rats with hippocampal lesions did not benefit from prior training. The findings show that prior experience can benefit learning even when the previously learned task and a new task are quite different. The concept of schema may be useful for understanding the benefits of prior experience. PMID- 29449456 TI - Place learning overrides innate behaviors in Drosophila. AB - Animals in a natural environment confront many sensory cues. Some of these cues bias behavioral decisions independent of experience, and action selection can reveal a stimulus-response (S-R) connection. However, in a changing environment it would be a benefit for an animal to update behavioral action selection based on experience, and learning might modify even strong S-R relationships. How animals use learning to modify S-R relationships is a largely open question. Three sensory stimuli, air, light, and gravity sources were presented to individual Drosophila melanogaster in both naive and place conditioning situations. Flies were tested for a potential modification of the S-R relationships of anemotaxis, phototaxis, and negative gravitaxis by a contingency that associated place with high temperature. With two stimuli, significant S-R relationships were abandoned when the cue was in conflict with the place learning contingency. The role of the dunce (dnc) cAMP-phosphodiesterase and the rutabaga (rut) adenylyl cyclase were examined in all conditions. Both dnc1 and rut2080 mutant flies failed to display significant S-R relationships with two attractive cues, and have characteristically lower conditioning scores under most conditions. Thus, learning can have profound effects on separate native S-R relationships in multiple contexts, and mutation of the dnc and rut genes reveal complex effects on behavior.

PMID- 29449458 TI - A Barnes maze for juvenile rats delineates the emergence of spatial navigation ability. AB - The neural bases of cognition may be greatly informed by relating temporally defined developmental changes in behavior with concurrent alterations in neural function. A robust improvement in performance in spatial learning and memory tasks occurs at 3 wk of age in rodents. We reported that the developmental increase of spontaneous alternation in a Y-maze was related to changes in temporal dynamics of fast glutamatergic synaptic transmission in the hippocampus. We also showed that, during allothetic behaviors in the Y-maze, network oscillation power increased at frequency bands known to support spatial learning and memory in adults. However, there are no discrete learning and memory phases during free exploration in the Y-maze. Thus, we adapted the Barnes maze for use with juvenile rats. Following a single platform exposure in dim light on the day before training (to encourage exploration), animals were trained on the subsequent 2 d in bright light to find a hidden escape box and then underwent a memory test 24 h later. During escape training, the older animals learned the task in 1 d, while the younger animals required 2 d and did not reach the performance of older animals. Long-term memory performance was also superior in the older animals. Thus, we have validated the use of the Barnes maze for this developmental period and established a timeline for the ontogeny of spatial navigation ability in this maze around 3 wk of age. Subsequent work will pair in vivo recording of hippocampal oscillations and single units with this task to help identify how hippocampal maturation might relate to performance improvements. PMID- 29449457 TI - The activity of thalamic nucleus reuniens is critical for memory retrieval, but not essential for the early phase of "off-line" consolidation. AB - Spatial navigation depends on the hippocampal function, but also requires bidirectional interactions between the hippocampus (HPC) and the prefrontal cortex (PFC). The cross-regional communication is typically regulated by critical nodes of a distributed brain network. The thalamic nucleus reuniens (RE) is reciprocally connected to both HPC and PFC and may coordinate the information flow within the HPC-PFC pathway. Here we examined if RE activity contributes to the spatial memory consolidation. Rats were trained to find reward following a complex trajectory on a crossword-like maze. Immediately after each of the five daily learning sessions the RE was reversibly inactivated by local injection of muscimol. The post-training RE inactivation affected neither the spatial task acquisition nor the memory retention, which was tested after a 20-d "forgetting" period. In contrast, the RE inactivation in well-trained rats prior to the maze exposure impaired the task performance without affecting locomotion or appetitive motivation. Our results support the role of the RE in memory retrieval and/or "online" processing of spatial information, but do not provide evidence for its engagement in "off-line" processing, at least within a time window immediately following learning experience. PMID- 29449460 TI - PFN2 and GAMT as common molecular determinants of axonal Charcot-Marie-Tooth disease. AB - BACKGROUND: Charcot-Marie-Tooth type 2 (CMT2) neuropathy is characterised by a vast clinical and genetic heterogeneity complicating its diagnosis and therapeutic intervention. Identification of molecular signatures that are common to multiple CMT2 subtypes can aid in developing therapeutic strategies and measuring disease outcomes. METHODS: A proteomics-based approach was performed on lymphoblasts from CMT2 patients genetically diagnosed with different gene mutations to identify differentially regulated proteins. The candidate proteins were validated through real-time quantitative PCR and western blotting on lymphoblast samples of patients and controls, motor neurons differentiated from patient-derived induced pluripotent stem cells (iPSCs) and sciatic nerves of CMT2 mouse models. RESULTS: Proteomic profiling of patient lymphoblasts resulted in the identification of profilin 2 (PFN2) and guanidinoacetate methyltransferase (GAMT) as commonly downregulated proteins in different genotypes compared with healthy controls. This decrease was also observed at the transcriptional level on screening 43 CMT2 patients and 22 controls, respectively. A progressive decrease in PFN2 expression with age was observed in patients, while in healthy controls its expression increased with age. Reduced PFN2 expression was also observed in motor neurons differentiated from CMT2 patient-derived iPSCs and sciatic nerves of CMT2 mice when compared with controls. However, no change in GAMT levels was observed in motor neurons and CMT2 mouse-derived sciatic nerves. CONCLUSIONS: We unveil PFN2 and GAMT as molecular determinants of CMT2 with possible indications of the role of PFN2 in the pathogenesis and disease progression. This is the first study describing biomarkers that can boost the development of therapeutic strategies targeting a wider spectrum of CMT2 patients.

AB - The comment and response concerning the report of oxidation of methane to methanol by water (Reports, 5 May 2017, p. 523) do not fully capture the implications of thermodynamic limitations. A nonisothermal process in which each cycle requires a large temperature swing and permits only substoichiometric methane conversion surely could not be carried out on any practical scale. PMID- 29449462 TI - Enantioselective C(sp3)-H bond activation by chiral transition metal catalysts. AB - Organic molecules are rich in carbon-hydrogen bonds; consequently, the transformation of C-H bonds to new functionalities (such as C-C, C-N, and C-O bonds) has garnered much attention by the synthetic chemistry community. The utility of C-H activation in organic synthesis, however, cannot be fully realized until chemists achieve stereocontrol in the modification of C-H bonds. This Review highlights recent efforts to enantioselectively functionalize C(sp3)-H bonds via transition metal catalysis, with an emphasis on key principles for both the development of chiral ligand scaffolds that can accelerate metalation of C(sp3)-H bonds and stereomodels for asymmetric metalation of prochiral C-H bonds by these catalysts.

PMID- 29449485 TI - Volatile chemical products emerging as largest petrochemical source of urban organic emissions. AB - A gap in emission inventories of urban volatile organic compound (VOC) sources, which contribute to regional ozone and aerosol burdens, has increased as transportation emissions in the United States and Europe have declined rapidly. A detailed mass balance demonstrates that the use of volatile chemical products (VCPs)-including pesticides, coatings, printing inks, adhesives, cleaning agents, and personal care products-now constitutes half of fossil fuel VOC emissions in industrialized cities. The high fraction of VCP emissions is consistent with observed urban outdoor and indoor air measurements. We show that human exposure to carbonaceous aerosols of fossil origin is transitioning away from transportation-related sources and toward VCPs. Existing U.S. regulations on VCPs emphasize mitigating ozone and air toxics, but they currently exempt many chemicals that lead to secondary organic aerosols. PMID- 29449486 TI - Natural selection and the predictability of evolution in Timema stick insects. AB - Predicting evolution remains difficult. We studied the evolution of cryptic body coloration and pattern in a stick insect using 25 years of field data, experiments, and genomics. We found that evolution is more difficult to predict when it involves a balance between multiple selective factors and uncertainty in environmental conditions than when it involves feedback loops that cause consistent back-and-forth fluctuations. Specifically, changes in color-morph frequencies are modestly predictable through time (r2 = 0.14) and driven by complex selective regimes and yearly fluctuations in climate. In contrast, temporal changes in pattern-morph frequencies are highly predictable due to negative frequency-dependent selection (r2 = 0.86). For both traits, however, natural selection drives evolution around a dynamic equilibrium, providing some predictability to the process. PMID- 29449487 TI - Wrapping with a splash: High-speed encapsulation with ultrathin sheets. AB - Many complex fluids rely on surfactants to contain, protect, or isolate liquid drops in an immiscible continuous phase. Thin elastic sheets can wrap liquid drops in a spontaneous process driven by capillary forces. For encapsulation by sheets to be practically viable, a rapid, continuous, and scalable process is essential. We exploit the fast dynamics of droplet impact to achieve wrapping of oil droplets by ultrathin polymer films in a water phase. Despite the violence of splashing events, the process robustly yields wrappings that are optimally shaped to maximize the enclosed fluid volume and have near-perfect seams. We achieve wrappings of targeted three-dimensional (3D) shapes by tailoring the 2D boundary of the films and show the generality of the technique by producing both oil-in water and water-in-oil wrappings. PMID- 29449488 TI - Natural noncanonical protein splicing yields products with diverse beta-amino acid residues. AB - Current textbook knowledge holds that the structural scope of ribosomal biosynthesis is based exclusively on alpha-amino acid backbone topology. Here we report the genome-guided discovery of bacterial pathways that posttranslationally create beta-amino acid-containing products. The transformation is widespread in bacteria and is catalyzed by an enzyme belonging to a previously uncharacterized radical S-adenosylmethionine family. We show that the beta-amino acids result from an unusual protein splicing process involving backbone carbon-carbon bond cleavage and net excision of tyramine. The reaction can be used to incorporate diverse and multiple beta-amino acids into genetically encoded precursors in Escherichia coli In addition to enlarging the set of basic amino acid components, the excision generates keto functions that are useful as orthogonal reaction sites for chemical diversification. PMID- 29449489 TI - Observation of three-photon bound states in a quantum nonlinear medium. AB - Bound states of massive particles, such as nuclei, atoms, or molecules, constitute the bulk of the visible world around us. By contrast, photons typically only interact weakly. We report the observation of traveling three photon bound states in a quantum nonlinear medium where the interactions between photons are mediated by atomic Rydberg states. Photon correlation and conditional phase measurements reveal the distinct bunching and phase features associated with three-photon and two-photon bound states. Such photonic trimers and dimers possess shape-preserving wave functions that depend on the constituent photon number. The observed bunching and strongly nonlinear optical phase are described by an effective field theory of Rydberg-induced photon-photon interactions. These observations demonstrate the ability to realize and control strongly interacting quantum many-body states of light. PMID- 29449490 TI - Dentate gyrus mossy cells control spontaneous convulsive seizures and spatial memory. AB - Temporal lobe epilepsy (TLE) is characterized by debilitating, recurring seizures and an increased risk for cognitive deficits. Mossy cells (MCs) are key neurons in the hippocampal excitatory circuit, and the partial loss of MCs is a major hallmark of TLE. We investigated how MCs contribute to spontaneous ictal activity and to spatial contextual memory in a mouse model of TLE with hippocampal sclerosis, using a combination of optogenetic, electrophysiological, and behavioral approaches. In chronically epileptic mice, real-time optogenetic modulation of MCs during spontaneous hippocampal seizures controlled the progression of activity from an electrographic to convulsive seizure. Decreased MC activity is sufficient to impede encoding of spatial context, recapitulating observed cognitive deficits in chronically epileptic mice. PMID- 29449491 TI - Species turnover promotes the importance of bee diversity for crop pollination at regional scales. AB - Ecologists have shown through hundreds of experiments that ecological communities with more species produce higher levels of essential ecosystem functions such as biomass production, nutrient cycling, and pollination, but whether this finding holds in nature (that is, in large-scale and unmanipulated systems) is controversial. This knowledge gap is troubling because ecosystem services have been widely adopted as a justification for global biodiversity conservation. Here we show that, to provide crop pollination in natural systems, the number of bee species must increase by at least one order of magnitude compared with that in field experiments. This increase is driven by species turnover and its interaction with functional dominance, mechanisms that emerge only at large scales. Our results show that maintaining ecosystem services in nature requires many species, including relatively rare ones. PMID- 29449492 TI - Structures of C1-IgG1 provide insights into how danger pattern recognition activates complement. AB - Danger patterns on microbes or damaged host cells bind and activate C1, inducing innate immune responses and clearance through the complement cascade. How these patterns trigger complement initiation remains elusive. Here, we present cryo electron microscopy analyses of C1 bound to monoclonal antibodies in which we observed heterogeneous structures of single and clustered C1-immunoglobulin G1 (IgG1) hexamer complexes. Distinct C1q binding sites are observed on the two Fc CH2 domains of each IgG molecule. These are consistent with known interactions and also reveal additional interactions, which are supported by functional IgG1 mutant analysis. Upon antibody binding, the C1q arms condense, inducing rearrangements of the C1r2s2 proteases and tilting C1q's cone-shaped stalk. The data suggest that C1r may activate C1s within single, strained C1 complexes or between neighboring C1 complexes on surfaces. PMID- 29449494 TI - Got milk, must conference. PMID- 29449493 TI - Lipopolysaccharide is transported to the cell surface by a membrane-to-membrane protein bridge. AB - Gram-negative bacteria have an outer membrane that serves as a barrier to noxious agents in the environment. This protective function is dependent on lipopolysaccharide, a large glycolipid located in the outer leaflet of the outer membrane. Lipopolysaccharide is synthesized at the cytoplasmic membrane and must be transported to the cell surface. To understand this transport process, we reconstituted membrane-to-membrane movement of lipopolysaccharide by incorporating purified inner and outer membrane transport complexes into separate proteoliposomes. Transport involved stable association between the inner and outer membrane proteoliposomes. Our results support a model in which lipopolysaccharide molecules are pushed one after the other in a PEZ dispenser like manner across a protein bridge that connects the inner and outer membranes. PMID- 29449495 TI - Evaluation of Self-reported Patient Experiences: Insights from Digital Patient Communities in Psoriatic Arthritis. AB - OBJECTIVE: To evaluate the types of experiences and treatment access challenges of patients with psoriatic arthritis (PsA) using self-reported online narratives. METHODS: English-language patient narratives reported between January 2010 and May 2016 were collected from 31 online sources (general health social networking sites, disease-focused patient forums, treatment reviews, general health forums, mainstream social media sites) for analysis of functional impairment and 40 online sources for assessment of barriers to treatment. Using natural language processing and manual curation, patient-reported experiences were categorized into 6 high-level concepts of functional impairment [social, physical, emotional, cognitive, role activity (SPEC-R), and general] and 6 categories to determine barriers to treatment access (coverage ineligibility, out-of-pocket cost, issues with assistance programs, clinical ineligibility, formulary placement/sequence, doctor guidance). The SPEC-R categorization was also applied to 3 validated PsA patient-reported outcome (PRO) instruments to evaluate their capacity to collect lower-level subconcepts extracted from patient narratives. RESULTS: Of 15,390 narratives collected from 3139 patients with PsA for exploratory analysis, physical concepts were the most common (81.5%), followed by emotional (50.7%), cognitive (20.0%), role activity (8.1%), and social (5.6%) concepts. Cognitive impairments and disease burden on family and parenting were not recorded by PsA PRO instruments. The most commonly cited barriers to treatment were coverage ineligibility (51.6%) and high out-of-pocket expenses (31.7%). CONCLUSION: Patients often discussed physical and emotional implications of PsA in online platforms; some commonly used PRO instruments in PsA may not identify cognitive issues or parenting/family burden. Nearly one-third of patients with PsA reported access barriers to treatment. PMID- 29449496 TI - Patient-reported Outcomes, Resource Use, and Social Participation of Patients with Rheumatoid Arthritis Treated with Biologics in Alberta: Experience of Indigenous and Non-indigenous Patients. AB - OBJECTIVE: To characterize patient-reported outcomes, resource use, and social participation during the course of biologic therapy for indigenous and non indigenous patients with rheumatoid arthritis (RA). METHODS: Patients initiating biologic therapy (2004 to 2012) were characterized longitudinally for patient reported outcomes including physical function measured by the Health Assessment Questionnaire, EQ-5D, well-being [Medical Outcomes Study Short Form-36 (SF-36)], and visual analog scales for pain, fatigue, sleep, stiffness, and patient's global assessment. Resource use, participation in activities of daily living, and effect of RA on work productivity were also evaluated for change during therapy. RESULTS: Indigenous patients (n = 90) presented with significantly worse scores for global evaluation, pain, sleep, quality of life, well-being, and physical function compared to non-indigenous patients (n = 1400). All patient-reported outcomes improved significantly during treatment for patients in both groups, but pain, sleep, and SF-36 physical health score changes occurred at slower rates for indigenous patients [difference in slopes 0.09 (p = 0.029), 0.08 (p = 0.043), and -0.35 (p = 0.03), respectively]. Performance of daily activities was affected for 50% of indigenous compared to 37% of non-indigenous patients, with more use of community services and assistance from others. Employed indigenous patients reported twice the number of days being unable to work owing to RA compared to employed non-indigenous patients. Of the unemployed indigenous patients, 82% indicated they had stopped working because of arthritis, versus 48% of non indigenous patients (p < 0.0001). CONCLUSIONS: Indigenous patients have greater consequences of RA regarding experienced symptoms, health-related quality of life, disruption of performance of activities of daily living, and reduced employment participation. PMID- 29449497 TI - Rheumatologists' Views and Experiences in Managing Rheumatoid Arthritis in Elderly Patients: A Qualitative Study. AB - OBJECTIVE: In this qualitative study we analyzed the (1) influence of age, comorbidity, and frailty on management goals in elderly patients with RA; (2) experiences of rheumatologists regarding the use of the Disease Activity Score at 28 joints (DAS28) to monitor disease activity; and (3) differences in management strategies in elderly patients with RA compared to their younger counterparts. METHODS: Rheumatologists were purposively sampled for a semistructured interview. Two readers independently read and coded the interview transcripts. Important concepts were taxonomically categorized and combined in overarching themes by using NVivo 11 software. RESULTS: Seventeen rheumatologists (mean age 44.8 yrs, SD 7.7 yrs; 29% male) from 9 medical centers were interviewed. Preserving an acceptable level of functioning was the most important management goal in patients >= 80 years and in patients with high levels of comorbidity and frailty. The DAS28 score less frequently steered the management strategy, because rheumatologists commented that comorbidity and an age-related erythrocyte sedimentation rate elevation might distort the DAS28 score. Instead, management of elderly patients highly depended on comorbidity, frailty, and their subsequent effects such as cognitive and physical decline, dependency, and polypharmacy. Presence of 1 or more of these factors frequently resulted in a less future oriented management approach with less emphasis on the maximal prevention of joint erosions. CONCLUSION: The treat-to-target model is not automatically adopted in the elderly patient population. Future evidence-based RA management recommendations for elderly patients with RA are needed and should account for factors such as comorbidity and frailty. PMID- 29449498 TI - Early Psoriatic Arthritis Versus Early Seronegative Rheumatoid Arthritis: Role of Dermoscopy Combined with Ultrasonography for Differential Diagnosis. AB - OBJECTIVE: Exclusion of psoriatic skin/nail lesions is important in differentiating early seronegative rheumatoid arthritis (ERA) from early polyarticular psoriatic arthritis (EPsA) and such manifestations may go unnoticed in atypical or minimally expressed cases. The aim of this study is to assess the usefulness of integrated rheumatological-dermatological evaluation in highlighting dermatological lesions missed on rheumatological examination and to investigate the role of ultrasonography (US) and dermoscopy in improving the recognition of subclinical psoriatic findings. METHODS: Patients with a new diagnosis of seropositive or seronegative ERA and EPsA with prevalent hands involvement were recruited. All were reassessed for the presence of psoriatic lesions during an integrated rheumatological-dermatological clinical evaluation and underwent hands US and proximal nailfold dermoscopy. RESULTS: Seventy-three consecutive subjects were included in the study: 25 with seropositive ERA, 23 with seronegative ERA, and 25 with EPsA. One-fourth of the subjects initially diagnosed as seronegative ERA presented cutaneous or nail psoriasis on integrated rheumatological-dermatological evaluation, thereby being reclassified as EPsA. The presence of at least 1 extrasynovial feature on hand US and dotted vessels on proximal nailfold dermoscopy was significantly associated with EPsA, with a sensitivity of 68.0% and 96.0% and a specificity of 88.1% and 83.3% for US and dermoscopy, respectively. When used together, specificity for PsA diagnosis raised to 90.5%. CONCLUSION: Integrated rheumatological-dermatological clinical evaluation may be helpful in identifying patients with EPsA misclassified as seronegative ERA. Additionally, US and dermoscopy may be used as supportive tools in identifying subclinical psoriatic features, which may come in handy in distinguishing EPsA from ERA. PMID- 29449499 TI - Clinical Correlates, Outcomes, and Predictors of Inflammatory Ocular Disease Associated with Rheumatoid Arthritis in the Biologic Era. AB - OBJECTIVE: Inflammatory ocular disease (IOD) is a rare but severe extraarticular manifestation of rheumatoid arthritis (ExRA) with high mortality. The aim of our study was to examine clinical characteristics of IOD in rheumatoid arthritis (RA) and their effect on disease severity and outcomes in recent years. METHODS: A retrospective cohort of RA patients with IOD evaluated between 1996 and 2013 was assembled and compared to RA comparators without IOD and matched for age, sex, and disease duration. RESULTS: We identified 92 patients (69% female; mean age 62 yrs) with IOD: 33 scleritis, 23 episcleritis, 21 peripheral ulcerative keratitis (PUK), 14 uveitis, and 1 with orbital inflammation. The majority of patients with scleritis, episcleritis, and PUK was seropositive versus uveitis (> 80% vs 62%, p = 0.048). PUK and scleritis were more symptomatic compared to episcleritis and uveitis, and often required systemic therapy. Time to resolution was longer in scleritis than episcleritis (p = 0.01). PUK, scleritis, and uveitis had severe ocular sequelae. Prevalence of severe ExRA (18% vs 4%, p = 0.004) and dry eye syndrome (42% vs 26%, p = 0.024) was higher among patients with IOD than comparators. The incidence of new ExRA over 5-year followup was also higher among cases (29% vs 11%, p = 0.022). Ten-year survival was similar among RA patients with and without IOD (66% vs 64%, p = 0.56), with no differences noted among IOD subtypes. CONCLUSION: This large single-center study highlights the variable presentation and outcomes of IOD in RA. Although ocular complications are associated with significant morbidity, it is reassuring that survival among those with IOD is now similar to those without ocular disease. PMID- 29449500 TI - The Cost-effectiveness of Biannual Serum Urate (SU) Monitoring after Reaching Target in Gout: A Health Economic Analysis Comparing SU Monitoring. AB - OBJECTIVE: The 2012 American College of Rheumatology gout management guidelines recommend monitoring serum urate (SU) every 6 months after target SU has been achieved. Our objective was to determine through modeling whether this testing would be cost-effective, considering financial cost, quality of life, and estimated change in adherence. METHODS: A cost-utility analysis was completed with a 3-arm model: (1) no regular urate monitoring; (2) annual urate monitoring; and (3) biannual urate monitoring. Inputs to the model for health-related quality of life, flare rate, and treatment location were drawn from the medical literature and modeled over a lifetime horizon. RESULTS: No monitoring was the least costly (Australian$6974) but least effective [13.51 quality-adjusted life yrs (QALY)], while annual urate monitoring [A$7117; 13.53 QALY; incremental cost effectiveness ratio (ICER) A$13,678/QALY gained] and biannual monitoring [A$7298; 13.54 QALY; ICER A$15,420 per QALY gained] were both cost-effective alternatives in base case analysis. Sensitivity analysis on both an individual component level and a probabilistic sensitivity analysis (PSA) demonstrated that the result was robust to changes in input variables. An improvement in adherence of >= 3.5% with biannual monitoring was all that was required to demonstrate cost-effectiveness. In PSA, the probability of biannual monitoring was 78%, no monitoring was 20%, and annual monitoring was 2%. CONCLUSION: The results suggest that biannual SU monitoring after attaining target SU is the most cost-effective, compared with no testing and annual testing. PMID- 29449501 TI - Diffusion-weighted Imaging Is a Sensitive and Specific Magnetic Resonance Sequence in the Diagnosis of Ankylosing Spondylitis. AB - OBJECTIVE: We tested the discriminatory capacity of diffusion-weighted magnetic resonance imaging (DWI) and its potential as an objective measure of treatment response to tumor necrosis factor inhibition in ankylosing spondylitis (AS). METHODS: Three cohorts were studied prospectively: (1) 18 AS patients with Bath Ankylosing Spondylitis Disease Activity Index > 4, and erythrocyte sedimentation rate > 25 and/or C-reactive protein > 10 meeting the modified New York criteria for AS; (2) 20 cases of nonradiographic axial spondyloarthritis (nr-axSpA) as defined by the Assessment of Spondyloarthritis international Society (ASAS) criteria; and (3) 20 non-AS patients with chronic low back pain, aged between 18 and 45 years, who did not meet the imaging arm of the ASAS criteria for axSpA. Group 1 patients were studied prior to and following adalimumab treatment. Patients were assessed by DWI and conventional magnetic resonance imaging (MRI), and standard nonimaging measures. RESULTS: At baseline, in contrast to standard nonimaging measures, DWI apparent diffusion coefficient (ADC) values showed good discriminatory performance [area under the curve (AUC) > 80% for Group 1 or 2 compared with Group 3]. DWI ADC values were significantly lower posttreatment (0.45 +/- 0.433 before, 0.154 +/- 0.23 after, p = 0.0017), but had modest discriminating capacity comparing pre- and posttreatment measures (AUC = 68%). This performance was similar to the manual Spondyloarthritis Research Consortium of Canada (SPARCC) scoring system. CONCLUSION: DWI is informative for diagnosis of AS and nr-axSpA, and has moderate utility in assessment of disease activity or treatment response, with performance similar to that of the SPARCC MRI score. PMID- 29449502 TI - The Crescentic Implication of Renal Outcomes in Proliferative Lupus Nephritis. AB - OBJECTIVE: To determine the association between crescents and renal outcomes, and the implications on therapeutic choices. METHODS: There were 231 patients with biopsy-proven proliferative lupus nephritis (PLN) who were divided into 4 groups: 59 patients were in the noncrescent group (NC); 59 patients exclusively with segmental crescents were in the segmental crescent group (SC); patients with circumferential crescents were categorized into 2 groups according to the crescentic ratio (C1 had 64 patients with <= 25%, and C2 had 49 patients with > 25%). Their baseline laboratory tests, histopathological manifestations, and outcomes were compared. RESULTS: Remission rates in NC, SC, C1, and C2 groups were 92.1%, 85.4%, 95.0%, and 76.1%, respectively. Fewer patients in the C2 group achieved complete remission than the other 3 groups. For longterm outcomes evaluated by serum creatinine (SCr) doubling or endstage renal disease (ESRD), the renal survival rate was lowest in the C2 group (p = 0.003). Including clinical and pathological variables in the Cox proportional hazard regression model separately, the multivariate analysis revealed that these were independent risk factors for SCr doubling or ESRD: baseline SCr (with every 1 mg/dl increase: HR = 1.834, 95% CI 1.465-2.296; p < 0.001), hemoglobin (with every 1 g/l increase: HR = 0.970, 95% CI 0.947-0.992; p = 0.009), the proportions of cellular crescents (with every 1% increase: HR = 1.040, 95% CI 1.015-1.066; p = 0.002) and fibrocellular crescents (with every 1% increase: HR = 1.085, 95% CI 1.013-1.163; p = 0.020), and severe renal tubular atrophy (HR = 5.348, 95% CI 1.278-22.373; p = 0.022). CONCLUSION: PLN with crescents > 25% had worse renal outcomes both in short and long terms. Proportions of cellular and fibrocellular crescents were independent risk factors for poor renal survival. PMID- 29449503 TI - Early Renin-angiotensin System Blockade Improved Short-term and Longterm Renal Outcomes in Systemic Lupus Erythematosus Patients with Antiphospholipid associated Nephropathy. AB - OBJECTIVE: To investigate the renal protective effects of early renin-angiotensin aldosterone system (RAAS) blockade with renin-angiotensin system inhibitors (RASI) in systemic lupus erythematosus (SLE) patients with antiphospholipid associated nephropathy (aPLN). METHODS: Medical data of 57 SLE patients with biopsy-proven aPLN were analyzed. Early RAAS blockade was defined as administration of RASI within 3 months after kidney biopsy and continued for >= 12 months. RESULTS: There was no significant difference in demographic data, laboratory findings, and renal histology by the time of kidney biopsy, except that the RASI group had higher proteinuria levels vs the non-RASI group [5.2 (2.8 8.8) vs 1.9 (0.6-2.8) g/d, p = 0.005, respectively] and higher prevalence of hypertension (75% vs 29%, p = 0.001, respectively). No significant difference between the 2 groups was observed in estimated glomerular filtration rate (eGFR), mean arterial pressure, and proteinuria level at 12 months after kidney biopsy. The improvement ratio of eGFR at 12 months was significantly higher in the RASI group versus the non-RASI group [26% (-5 to 86) vs -2% (-20 to 20), p = 0.028, respectively], and the rate of change in eGFR beyond 12 months was similar between the 2 groups. During a mean followup of 80 months, 4 (23%) patients in the non-RASI group and 3 (8%) patients in the RASI group developed kidney disease progression. Early RAAS blockade significantly decreased the risk of kidney disease progression [HR = 0.11 (0.02-0.59); p = 0.010]. Proteinuria and hypertension controls were similar between the 2 groups. CONCLUSION: Early RAAS blockade improved the short-term and longterm renal outcomes in SLE patients with aPLN. The renal protective effect of RASI was independent of its antihypertensive and antiproteinuric effects. PMID- 29449505 TI - Detection of Crohn Disease in Patients with Spondyloarthropathy: The SpACE Capsule Study. AB - OBJECTIVE: Inflammatory bowel disease (IBD) is generally reported to be associated with spondylarthropathies (SpA) in 5%-15% of cases. Systematic colonoscopic assessment by protocol demonstrated mucosal inflammation characteristic of Crohn disease (CD) in up to one-third of patients with SpA. Video capsule endoscopy (CE) is a superior diagnostic tool to detect small bowel mucosal disease. Our study compared the accuracy of CE to standard colonoscopy for detection of inflammatory bowel lesions in patients with SpA, and to describe predictors of small bowel inflammation (SBI) in this cohort. METHODS: Prospective cross-sectional study of adult patients followed for SpA. Patients were evaluated by CE and standard colonoscopy with biopsies. SBI was quantified using the Lewis Score. Additional screening tests included fecal calprotectin (FCP), C-reactive protein (CRP), and a diagnostic panel of serologic, inflammatory and genetic tests (SGI). RESULTS: There were 64 patients recruited (53% female, mean age 42 +/- 13 yrs). Chronic gastrointestinal (GI) symptoms were present in 57%. CE revealed significant SBI in 27/64 (42.2%), compared to 7/64 (10.9%) by standard colonoscopy (p = 0.035). Elevated FCP was associated with small bowel CD (OR 4.5, 95% CI 1.01-19.9; p = 0.042). No correlation was observed with presence of GI symptoms, CRP, or SGI results. Finding CD led to a change in management in 65.2% of cases. CONCLUSION: CE uncovered SBI consistent with CD in 42.2% of patients with SpA, with a significant incremental yield over colonoscopy of 31%. FCP levels were significantly correlated with CE results, while GI symptoms and SGI results were poor predictors of SBI. PMID- 29449504 TI - Response to Tumor Necrosis Factor Inhibition in Male and Female Patients with Ankylosing Spondylitis: Data from a Swiss Cohort. AB - OBJECTIVE: To investigate sex differences in connection with the effectiveness of tumor necrosis factor inhibitors (TNFi) in patients with ankylosing spondylitis (AS). METHODS: A total of 440 patients with AS (294 men; 146 women) initiating a first TNFi in the prospective Swiss Clinical Quality Management Cohort were included. We evaluated the proportion of patients achieving the 20% and 40% improvement in the Assessment of Spondyloarthritis international Society criteria (ASAS20 and ASAS40) as well as Ankylosing Spondylitis Disease Activity Score (ASDAS) improvement and status scores at 1 year. Patients having discontinued TNFi were considered nonresponders. Logistic regression analyses were performed to adjust for important predictors of response. RESULTS: Compared to men, female patients had lower mean C-reactive protein levels, better spinal mobility, and more peripheral disease at the start. There was no sex disparity with regard to the ASDAS, the Bath Ankylosing Spondylitis Disease Activity and Functional indices, and the quality of life. At 1 year, 52% of women and 63% of men achieved an ASAS20 response (OR 0.63, 95% CI 0.37-1.07, p = 0.09). An inactive disease status (ASDAS < 1.3) was reached by 18% of women and 26% of men (OR 0.65, 95% CI 0.32-1.27, p = 0.22). These sex differences in response to TNFi were more pronounced in adjusted analyses (OR 0.34, 95% CI 0.16-0.71, p = 0.005 for ASAS20 and OR 0.10, 95% CI 0.03-0.31, p < 0.001 for ASDAS < 1.3) and confirmed for all the other outcomes assessed. CONCLUSION: In AS, fewer women respond to TNFi and women show a reduced response in comparison to men. PMID- 29449506 TI - Whole-body Magnetic Resonance Imaging in Axial Spondyloarthritis: Reduction of Sacroiliac, Spinal, and Entheseal Inflammation in a Placebo-controlled Trial of Adalimumab. AB - OBJECTIVE: To investigate whether adalimumab (ADA) reduces whole-body (WB-) magnetic resonance imaging (MRI) indices for inflammation in the entheses, peripheral joints, sacroiliac joints, spine, and the entire body in patients with axial spondyloarthritis (axSpA). METHODS: An investigator-initiated, randomized, placebo-controlled, double-blinded 48-week followup trial included 49 patients with axSpA, who had Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) >= 4.0 despite treatment with nonsteroidal antiinflammatory drugs and a clinical indication for tumor necrosis factor inhibitor treatment. Patients were randomized to subcutaneous ADA 40 mg or placebo every other week for 6 weeks; thereafter, all patients received ADA. Conventional MRI and WBMRI were performed at weeks 0, 6, 24, and 48. The primary WBMRI endpoint was the proportion of patients with an improvement in WBMRI total inflammation index above the smallest detectable change (SDC) at Week 6. RESULTS: The primary WBMRI endpoint (improvement of SDC > 2.3) was met in 11 (44%) patients in the ADA group and 3 (13%) patients in the placebo group (p = 0.025, Fisher's exact test). The primary conventional MRI endpoint, the minimally important change in Spondyloarthritis Research Consortium of Canada Spine MRI Inflammation Index at Week 6, was achieved by 9 (36%) patients in the ADA group and 4 (17%) patients in the placebo group (p = 0.20). The primary clinical endpoint, BASDAI reduction > 50% or 2.0 at Week 24, was attained by 32 (65%) patients. CONCLUSION: ADA provided significant reductions in WBMRI indices of peripheral, axial, and whole-body inflammation in patients with axSpA. WBMRI is promising for objective assessment and monitoring of peripheral and axial disease activity in future clinical trials.

The devices record signal amplitude or duration as changes in the ratio of mutually exclusive DNA sequences (CAMERA 1) or as single base modifications (CAMERA 2). We achieved recording of multiple stimuli in bacteria or mammalian cells, including exposure to antibiotics, nutrients, viruses, light, and changes in Wnt signaling. When recording to multicopy plasmids, reliable readout requires as few as 10 to 100 cells. The order of stimuli can be recorded through an overlapping guide RNA design, and memories can be erased and re-recorded over multiple cycles. CAMERA systems serve as "cell data recorders" that write a history of endogenous or exogenous signaling events into permanent DNA sequence modifications in living cells. PMID- 29449509 TI - Predicting reaction performance in C-N cross-coupling using machine learning. AB - Machine learning methods are becoming integral to scientific inquiry in numerous disciplines. We demonstrated that machine learning can be used to predict the performance of a synthetic reaction in multidimensional chemical space using data obtained via high-throughput experimentation. We created scripts to compute and extract atomic, molecular, and vibrational descriptors for the components of a palladium-catalyzed Buchwald-Hartwig cross-coupling of aryl halides with 4 methylaniline in the presence of various potentially inhibitory additives. Using these descriptors as inputs and reaction yield as output, we showed that a random forest algorithm provides significantly improved predictive performance over linear regression analysis. The random forest model was also successfully applied to sparse training sets and out-of-sample prediction, suggesting its value in facilitating adoption of synthetic methodology. PMID- 29449508 TI - Multiplexed and portable nucleic acid detection platform with Cas13, Cas12a, and Csm6. AB - Rapid detection of nucleic acids is integral for clinical diagnostics and biotechnological applications. We recently developed a platform termed SHERLOCK (specific high-sensitivity enzymatic reporter unlocking) that combines isothermal preamplification with Cas13 to detect single molecules of RNA or DNA. Through characterization of CRISPR enzymology and application development, we report here four advances integrated into SHERLOCK version 2 (SHERLOCKv2) (i) four-channel single-reaction multiplexing with orthogonal CRISPR enzymes; (ii) quantitative measurement of input as low as 2 attomolar; (iii) 3.5-fold increase in signal sensitivity by combining Cas13 with Csm6, an auxiliary CRISPR-associated enzyme; and (iv) lateral-flow readout. SHERLOCKv2 can detect Dengue or Zika virus single stranded RNA as well as mutations in patient liquid biopsy samples via lateral flow, highlighting its potential as a multiplexable, portable, rapid, and quantitative detection platform of nucleic acids. PMID- 29449510 TI - Winter color polymorphisms identify global hot spots for evolutionary rescue from climate change. AB - Maintenance of biodiversity in a rapidly changing climate will depend on the efficacy of evolutionary rescue, whereby population declines due to abrupt environmental change are reversed by shifts in genetically driven adaptive traits. However, a lack of traits known to be under direct selection by anthropogenic climate change has limited the incorporation of evolutionary processes into global conservation efforts. In 21 vertebrate species, some individuals undergo a seasonal color molt from summer brown to winter white as camouflage against snow, whereas other individuals remain brown. Seasonal snow duration is decreasing globally, and fitness is lower for winter white animals on snowless backgrounds. Based on 2713 georeferenced samples of known winter coat color-from eight species across trophic levels-we identify environmentally driven clinal gradients in winter coat color, including polymorphic zones where winter brown and white morphs co-occur. These polymorphic zones, underrepresented by existing global protected area networks, indicate hot spots for evolutionary rescue in a changing climate. PMID- 29449511 TI - CRISPR-Cas12a target binding unleashes indiscriminate single-stranded DNase activity. AB - CRISPR-Cas12a (Cpf1) proteins are RNA-guided enzymes that bind and cut DNA as components of bacterial adaptive immune systems. Like CRISPR-Cas9, Cas12a has been harnessed for genome editing on the basis of its ability to generate targeted, double-stranded DNA breaks. Here we show that RNA-guided DNA binding unleashes indiscriminate single-stranded DNA (ssDNA) cleavage activity by Cas12a that completely degrades ssDNA molecules. We find that target-activated, nonspecific single-stranded deoxyribonuclease (ssDNase) cleavage is also a property of other type V CRISPR-Cas12 enzymes. By combining Cas12a ssDNase activation with isothermal amplification, we create a method termed DNA endonuclease-targeted CRISPR trans reporter (DETECTR), which achieves attomolar sensitivity for DNA detection. DETECTR enables rapid and specific detection of human papillomavirus in patient samples, thereby providing a simple platform for molecular diagnostics.

PMID- 29449515 TI - [Therapeutic Effects of Low-Dose Bevacizumab for the Treatment of Recurrent Brain Metastases]. AB - OBJECTIVE: Molecularly targeted therapy has been adopted to treat a number of cancers. Bevacizumab, a recombinant humanized monoclonal antibody against vascular endothelial growth factor, is a representative agent used in molecularly targeted therapeutic regimens. However, the therapeutic effect of bevacizumab for the treatment of brain metastases remains unknown. We report the clinical effects of low dose bevacizumab(<=2.5mg/kg/week)to treat recurrent brain metastases. METHODS: We retrospectively analyzed patients with brain metastases who had been treated with bevacizumab between 2012 and 2016 at our institution. We identified clinical characteristics, including age, gender, primary tumor site, dose of bevacizumab, therapeutic and adverse effects, and magnetic resonance imaging results. The lesions were assessed with the RECIST criteria based on gadolinium enhanced T1-weighted, T2-weighted, and FLAIR images. Statistical analysis was performed using t-test and Fisher's exact test. RESULTS: The cohort comprised 26 patients(8 men, 18 women)with a median age of 61 years(range 39-82 years). There were no significant clinical differences between the low dose and non-low dose groups. Patients in the low dose group did not report any adverse effects from bevacizumab. Three patients with brain metastases from colon cancer are illustrated to report the clinical course of low dose bevacizumab. CONCLUSION: Low dose bevacizumab may be a safe and effective therapeutic option to treat recurrent brain metastases from bevacizumab-sensitive cancers. PMID- 29449516 TI - [A Case of a Ruptured Cerebral Aneurysm Associated with Microscopic Polyangiitis]. AB - CASE: A 71-year-old woman was receiving dialysis for microscopic polyangiitis(MPA). She was transported to the emergency room after developing a headache and losing consciousness. She was in a coma and had dense left paralysis. Head computed tomography(CT)showed a subarachnoid hemorrhage. Head three-dimensional CT angiography showed an aneurysm proximal to the right M2(inferior trunk), which was considered as the source of bleeding. We performed an emergency aneurysm clipping surgery. However, we placed a permanent clip on the arterial wall defect when the clip detached from the parent artery. Pathological examination of the aneurysm revealed that the layered structure of the artery was damaged because of fibrin degeneration, suggesting that the aneurysm was caused by vasculitis. Coma persisted after surgery, and the patient was transferred to another hospital. DISCUSSION: We found only one report demonstrating an association between a cerebral aneurysm and MPA. Aneurysms resulting from vasculitis are common at the periphery, rather than at vessel bifurcations. Cyclic inflammatory activity causes progressive destruction of the blood vessel wall, further expanding the lumen and forming an aneurysm. Therefore, such aneurysms are more fragile than true aneurysms, and are more likely to be damaged or detached during surgery, as in the present case. Trapping of the parent artery should be considered when the aneurysm is damaged or detached. Accordingly, preoperative planning could anticipate the need for superficial temporal artery to middle cerebral artery bypass. PMID- 29449517 TI - [A Case of Moyamoya Disease with Postoperative Cerebral Hyperperfusion Syndrome Followed by Cerebral Infarction due to Watershed Shift]. AB - The concept of "watershed shift"(WS)has been proposed as a cause of the ischemic complications following a superficial temporal artery-middle cerebral artery(STA MCA)bypass operation performed for the management of moyamoya disease. Previous reports have observed that only 1.2-5.7% of the patients who underwent a bypass operation for the management of moyamoya disease developed cerebral infarction secondary to the WS phenomenon. To date, the WS phenomenon has not been objectively proven on imaging studies. We describe a 39-year-old woman who presented with right facial palsy and aphasia. Magnetic resonance imaging revealed cerebral infarction in the left frontal lobe secondary to moyamoya disease. Three days after undergoing the left STA-MCA bypass procedure, she showed deterioration in aphasia secondary to the occurrence of cerebral hyperperfusion syndrome(CHPS). Diffusion-weighted imaging(DWI)performed on postoperative day(POD)1 and 5 showed no area of high signal intensity. DWI performed on POD 8 showed an area of high signal intensity in the deep white matter of the left parietal lobe outside the range of the craniotomy. Postoperative fusion images of computed tomography angiography and DWI performed on POD 8 showed that the blood flow through the MCA from the bypass graft and that through the posterior cerebral artery crossed each other at the surface of the subcortical infarction. In the present case, the WS could be directly confirmed on imaging studies, and the cerebral infarction may have occurred secondary to WS concomitant with CHPS. Clinicians need to be aware of the WS phenomenon even after performing a direct bypass to treat adults with moyamoya disease.

AB - A 73-year-old man was admitted at another hospital after a traffic accident. The diagnosis was cervical vertebral fracture. Despite conservative treatment, 5 days later he manifested dysarthria due to cerebellar infarction and was transferred to our hospital. Imaging studies revealed right vertebral arterial dissection at the level of the axial fracture. We performed percutaneous transluminal angioplasty with stenting to address his subacute vertebral artery dissection prior to treating the cervical vertebral fracture using external fixation. His clinical course was good;ischemia did not recur after stenting and his dysarthria disappeared upon rehabilitation. Cerebral angiograms obtained 6 months later revealed no significant in-stent restenosis. While medical management tends to be the first-line treatment of traumatic vertebral artery dissection, percutaneous transluminal angioplasty with stenting is necessary before treating other traumatic lesions to prevent neurologic events.

AB - We present a rare case of supratentorial meningeal melanoma associated with ipsilateral nevus of Ota, and a review of the literature. The patient was a 32 year-old man with a right-sided nevus of Ota, presenting with unconsciousness. His CT and MRI scans revealed an extra axial tumor with dural tail signs; no lesion was detected on systemic examination. Intraoperatively, the tumor demonstrated black hyperpigmentation and was histologically diagnosed as malignant melanoma. Following surgery, he received radiotherapy and chemotherapy. For over a year and a half, the patient has shown no recurrence of the lesion. PMID- 29449520 TI - [A Case of Hypertrophic Pachymeningitis with Symptomatic Venous Congestion due to Sinus Stenosis]. AB - We report a patient with hypertrophic pachymeningitis and symptomatic stenosis of the superior sagittal sinus. A 71-year-old man presented with right hemiparesis, sensory-dominant aphasia, and right hemispatial neglect that had been worsening over 2 weeks. Computed tomography showed isodense crescent-shaped lesions deforming the surface of the left cerebral hemisphere, mimicking a subdural hematoma with atypical perifocal edema in the left parietal lobe. Magnetic resonance imaging showed diffuse thickening of the dura mater with contrast enhancement of his left cerebral hemisphere. Histopathological examination of the dural specimen obtained by burr-hole surgery revealed mononuclear inflammatory cell infiltration, and he was diagnosed with hypertrophic pachymeningitis. Dynamic cerebral angiography showed superior sagittal sinus stenosis with reduced venous flow through the left parietal lobe. Administration of high-dose steroid therapy led to neurological improvement. In the case of a subdural mass with atypical parenchymal edema such as a chronic subdural hematoma, other etiology should be taken into consideration.

AB - BACKGROUND Disparities research has traditionally focused on patient-level variables to ascertain predominant risk factors driving differences in outcomes for African-American (AA) kidney transplant recipients. Our objectives were to determine the magnitude and impact of transplant center variability for graft outcome disparities. MATERIAL AND METHODS This was a retrospective cohort study analyzing 25 years of U.S. national transplant registry data at both the patient and center levels using univariate descriptive statistics and multivariable modeling. RESULTS A total of 257,024 recipients from 191 centers were analyzed; AAs represented 31.1% of recipients. After adjusting for baseline characteristics, AAs had 42% higher risk of graft loss (aHR 1.42, 95% CI 1.39 to 1.45; p<0.001). Center variability for graft outcome disparities in AAs was significant (race*center interaction term p<0.05), with the aHRs ranging from 0.5 to 4.9; 46% of centers demonstrated a non-statistically significant disparity (aHR p>0.05) and 25% of centers had a large AA disparity (aHR >1.75). In a more recent transplant time period (2000-14), overall racial disparities decreased but center-level disparities increased in variability. Center-level factors significantly associated with increasing disparity included higher acute rejection rates, fewer transplants per year, longer length of stay, lower use of calcineurin inhibitors (CNI), and lower living donor rates. CONCLUSIONS There is evidence of significant center-level variability in graft outcome disparities for AA kidney recipients. Further, there appears to be a number of center-level factors associated with this variability, including acute rejection rates, CNI use, number of transplants per year, and, in recent years, low living donor rates. PMID- 29449525 TI - Anterior Approach to En Bloc Resection in Left-Sided Retroperitoneal Sarcoma with Adjacent Organ Involvement: A Study of 25 Patients in a Single Center. AB - BACKGROUND There is no standard surgical approach for the management of retroperitoneal sarcoma. The aim of this clinical study was to describe the experience of an anterior approach to en bloc resection in left-sided retroperitoneal sarcoma with adjacent organ involvement. MATERIAL AND METHODS This retrospective clinical study included 25 patients who were diagnosed with left-sided retroperitoneal sarcoma and underwent tumor resection at a single center between May 2012 and July 2017. All patients had tumors that were adjacent to the left colon, pancreas, left kidney, left adrenal gland, and psoas major; some of the tumors were adjacent to the diaphragm, stomach, and small intestine. An anterior approach was used to remove the left-sided retroperitoneal tumor with the adhesive organs en bloc, an approach that is described in detail. The value of this surgical approach was evaluated based on the histopathological findings, postoperative complications, and patient follow-up. RESULTS The median number of resected organs, in addition to the retroperitoneal tumor, was 8 (range, 6-10). Complete macroscopic tumor resection was achieved in 23 cases (92%). Twenty-four patients (96%) had tumor infiltration of at least one organ or the surrounding fat. Three patients (12%) experienced Grade III and IV postoperative morbidities. The one-year disease-free survival rate was 91.3% among patients with macroscopically complete resections. The one-year overall survival rate was 83.2%. CONCLUSIONS In selected patients, left-sided retroperitoneal sarcoma associated with local organ involvement can be surgically managed using an anterior approach with en bloc resection of adjacent organs. PMID- 29449526 TI - Raised Serum Levels of Syndecan-1 (CD138), in a Case of Acute Idiopathic Systemic Capillary Leak Syndrome (SCLS) (Clarkson's Disease). AB - BACKGROUND Systemic capillary leak syndrome (SCLS) (Clarkson's disease) is a rare disorder of unknown etiology, characterized by transient episodes of hypotension, and the microvascular leak of fluids into the peripheral tissues, resulting in edema. Between 80-90% of patients with SCLS have a concomitant monoclonal gammopathy. Although translational in vitro studies have implicated vascular endothelial barrier dysfunction in the etiology of SCLS, the etiology and disease associations in clinical cases remain unknown. CASE REPORT We report a case of SCLS in a 49-year-old woman who initially presented with an upper respiratory tract infection, which was complicated by edema and compartment syndromes in the extremities that required fasciotomies. Serum levels of the cell surface heparan sulfate proteoglycan, syndecan-1 (CD138), a measure of endothelial surface glycocalyx (ESG) damage, were measured by enzyme-linked immunoassay (ELISA), peaked at up to 500 ng/mL (reference range, 50-100 ng/mL) and normalized on disease remission. CONCLUSIONS This case report supports the view that damage to the microvascular endothelium, has a role in the pathogenesis of acute SCLS. This case also indicated that monitoring serum levels of syndecan-1 (CD138) might be used to monitor the progression and resolution of episodes of SCLS. PMID- 29449527 TI - TR4 nuclear receptor suppresses HCC cell invasion via downregulating the EphA2 expression. AB - Early studies indicated that testicular nuclear receptor 4 (TR4) could function as a suppressor in the transcriptional regulation of the HBV core gene expression, which might then influence the development of hepatocellular carcinoma (HCC). The direct linkage between TR4 and HCC progression, however, remained unclear. Here, via a human clinical sample survey, we found that 13 of the 18 HCC patients studied had lower TR4 expression in metastatic lesions than in matched primary HCC lesions, suggesting that TR4 may play a negative role in HCC metastasis. Results from in vitro cell migration/invasion studied confirmed that TR4 could suppress HCC cell migration/invasion. Mechanism dissection revealed that TR4 might function through downregulating ephrin type-A receptor 2 (EphA2) expression at the transcriptional level via direct binding to the TR4REs located on the 5' promoter of EphA2 to suppress HCC cell migration/invasion. Targeting the EphA2 via EphA2-siRNA partially reversed the enhanced HCC cell migration/invasion with confirmed TR4 knockdown. Notably, results from preclinical studies using in vivo mouse model with orthotopic xenograft of HCC LM3 cells also confirmed the in vitro findings. Taking these findings together, preclinical studies using multiple in vitro HCC cell lines and an in vivo mouse model all led to the conclusion that TR4 may function as a suppressor of HCC metastasis and that targeting this newly identified TR4-EphA2 signaling may improve our ability to suppress HCC metastasis. PMID- 29449528 TI - ALS-related human cortical and motor neurons survival is differentially affected by Sema3A. AB - Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by cell death of upper and lower motor neurons (MNs). The cause of MN cell loss is not completely understood but involves both cell autonomous and non-cell autonomous mechanisms. Numerous molecules have been implicated to be involved in the death of MNs. One such candidate is semaphorin 3A (Sema3A). In ALS patients, Sema3A was shown to be significantly upregulated in the motor cortex and downregulated in the spinal cord. In the mouse, Sema3A was shown to be an axon repellent molecule for MNs. Sema3A could also induce death of different neuronal types that are also repelled by it, including sensory, sympathetic, retinal, and cortical neurons. In contrast, astrocyte-specific knockout of Sema3A results in motor neuron cell death, consistent with the idea that Sema3A is a survival factor for mouse motor neurons. Here, we tested the response of human cortical neurons and spinal cord MNs to Sema3A. We found that Sema3A enhances the survival of spinal cord MNs. In contrast, Sema3A reduces the survival of cortical neurons. Thus, both upregulation of Sema3A in the cortex, or downregulation in the spinal cord of ALS patients is likely to directly contribute to MNs cell loss in ALS patients. PMID- 29449529 TI - Gambogenic acid inhibits fibroblast growth factor receptor signaling pathway in erlotinib-resistant non-small-cell lung cancer and suppresses patient-derived xenograft growth. AB - Erlotinib resistance causes a high degree of lethality in non-small-cell lung cancer (NSCLC) patients. The high expression and activation of several receptor tyrosine kinases, such as JAK/STAT3, c-Met, and EGFR, play important roles in drug resistance. The development of tyrosine kinase inhibitors is urgently required in the clinic. Our previous study found that Gambogenic acid (GNA), a small molecule derived from the traditional Chinese medicine herb gamboge, induced cell death in several NSCLC cell lines through JAK/STAT3 inhibition. In this study, we investigated the mechanism of action of GNA in erlotinib-resistant NSCLC and patient-derived cells. The inhibition of GNA on FGFR signaling pathway was examined using biochemical kinase assays. NSCLC cell lines (HCC827, HCC827 Erlotinib-resistant, and H1650) and primary cells from patients with NSCLC with clinical resistance to erlotinib were treated with GNA, erlotinib, or their combination. Both kinase assays and cell- based assays showed that GNA inhibits the phosphorylation of multiple kinases in FGFR signaling pathway in NSCLC. The combination of GNA and erlotinib significantly attenuates the tumor growth of HCC827 and erlotinib-resistant HCC827 xenografts with low toxicity. Importantly, GNA significantly suppresses tumor growth in a lung patient-derived xenograft (PDX) model with FGFR fusion and low EGFR expression. Our findings provide preclinical evidence for using GNA as an FGFR signaling pathway inhibitor to overcome erlotinib resistance in NSCLC treatment or to enhance erlotinib efficacy when used as a combined administration. PMID- 29449530 TI - The type 2 diabetes-associated HMG20A gene is mandatory for islet beta cell functional maturity. AB - HMG20A (also known as iBRAF) is a chromatin factor involved in neuronal differentiation and maturation. Recently small nucleotide polymorphisms (SNPs) in the HMG20A gene have been linked to type 2 diabetes mellitus (T2DM) yet neither expression nor function of this T2DM candidate gene in islets is known. Herein we demonstrate that HMG20A is expressed in both human and mouse islets and that levels are decreased in islets of T2DM donors as compared to islets from non diabetic donors. In vitro studies in mouse and human islets demonstrated that glucose transiently increased HMG20A transcript levels, a result also observed in islets of gestating mice. In contrast, HMG20A expression was not altered in islets from diet-induced obese and pre-diabetic mice. The T2DM-associated rs7119 SNP, located in the 3' UTR of the HMG20A transcript reduced the luciferase activity of a reporter construct in the human beta 1.1E7 cell line. Depletion of Hmg20a in the rat INS-1E cell line resulted in decreased expression levels of its neuronal target gene NeuroD whereas Rest and Pax4 were increased. Chromatin immunoprecipitation confirmed the interaction of HMG20A with the Pax4 gene promoter. Expression levels of Mafa, Glucokinase, and Insulin were also inhibited. Furthermore, glucose-induced insulin secretion was blunted in HMG20A depleted islets. In summary, our data demonstrate that HMG20A expression in islet is essential for metabolism-insulin secretion coupling via the coordinated regulation of key islet-enriched genes such as NeuroD and Mafa and that depletion induces expression of genes such as Pax4 and Rest implicated in beta cell de differentiation. More importantly we assign to the T2DM-linked rs7119 SNP the functional consequence of reducing HMG20A expression likely translating to impaired beta cell mature function. PMID- 29449531 TI - CAR-T cells: the long and winding road to solid tumors. AB - Adoptive cell therapy of solid tumors with reprogrammed T cells can be considered the "next generation" of cancer hallmarks. CAR-T cells fail to be as effective as in liquid tumors for the inability to reach and survive in the microenvironment surrounding the neoplastic foci. The intricate net of cross-interactions occurring between tumor components, stromal and immune cells leads to an ineffective anergic status favoring the evasion from the host's defenses. Our goal is hereby to trace the road imposed by solid tumors to CAR-T cells, highlighting pitfalls and strategies to be developed and refined to possibly overcome these hurdles. PMID- 29449532 TI - Senescence-associated secretory factors induced by cisplatin in melanoma cells promote non-senescent melanoma cell growth through activation of the ERK1/2-RSK1 pathway. AB - Although targeted therapy and immunotherapy greatly improve the outcome of melanoma, drug resistance and low response rates still maintain the unsubstitutability of traditional chemotherapy. Cisplatin (CDDP) is widely used in different types of tumours with high response rates, but it generally has low efficiency in melanoma. The mechanisms underpinning the phenomena are not sufficiently understood. Here we demonstrated that various melanoma cell lines adopted senescence phenotype after CDDP treatment in contrast to the other types of tumour cells. CDDP treatment induced melanoma A375 cells into senescence through the sequential activation of the DNA damage response and the P53/P21 pathway. All the senescent melanoma cells induced by CDDP alone or the combination of CDDP and dacarbazine developed robust senescence-associated secretory phenotype (SASP), that is, the secretion of multiple cytokines. IL 1alpha was an early component and an upstream regulator of SASP. Similarly, CDDP either alone or combined with dacarbazine could induce melanoma cell senescence and SASP in either A375 or B16F10 melanoma xenograft mice. The supernatant of senescent A375 cells promoted the growth of normal non-senescent A375 cells and enhanced their expression and secretion of IL-8 through the activation of the ERK1/2-RSK1 pathway. The transplantation of non-senescent and senescent A375 cells together into nude mice showed accelerated tumour growth compared with transplanting non-senescent cells alone; no tumours developed when transplanting senescent cells alone. Following CDDP administration in A375-bearing mice, the intratumour injection of neutralisation antibodies targeting the SASP factors IL 1alpha or IL-8 evidently delayed tumour growth. The results suggest that the CDDP induced senescent melanoma cells promote non-senescent cells proliferation through the activation of ERK1/2-RSK1 pathway by the SASP factors. Cell senescence and concomitant SASP may be the particular mechanisms for melanoma to resist chemotherapeutics. PMID- 29449533 TI - Non-alcoholic fatty liver disease severity is modulated by transglutaminase type 2. AB - Non-alcoholic fatty liver disease (NAFLD) is one of the most important liver diseases worldwide. Currently, no effective treatment is available, and NAFLD pathogenesis is incompletely understood. Transglutaminase type 2 (TG2) is a ubiquitous enzyme whose dysregulation is implicated in the pathogenesis of various human diseases. Here we examined the impact of TG2 on NAFLD progression using the high-fat-diet-induced model in both wild-type and TG2-deficient mice. Animals were fed with a standard chow diet or a high-fat diet (42% of the energy from fat) for 16 weeks. Results demonstrated that the absence of a functional enzyme, which causes the impairment of autophagy/mitophagy, leads to worsening of disease progression. Data were confirmed by pharmacological inhibition of TG2 in WT animals. In addition, the analysis of human liver samples from NAFLD patients validated the enzyme's involvement in the liver fat disease pathogenesis. Our findings strongly suggest that TG2 activation may offer protection in the context of NAFLD, thus representing a novel therapeutic target for tackling the NAFLD progression. PMID- 29449534 TI - TRIM36, a novel androgen-responsive gene, enhances anti-androgen efficacy against prostate cancer by inhibiting MAPK/ERK signaling pathways. AB - Hormone therapy drugs, such as bicalutamide and enzalutamide, directed against prostate cancer focus on androgen receptor (AR) signaling and are initially effective, but the disease progresses to lethality as resistance to these drugs develops. A method to prolong the drug response time and improve the drug efficacy is still unavailable. TRIM36 was reported as a novel androgen signaling target gene and is upregulated in prostate cancer. In this study, we found that 63.4% (64/95) of PCa in TMA expressed the TRIM36 protein. Interestingly, patients with negative TRIM36 expression had a shorter biochemical recurrence-free survival. TRIM36 expression was significantly associated with the Gleason score (P = 0.005), delayed prostate cancer cell cycle progression and inhibited cell proliferation in vitro and in vivo, and these effects were mediated via inhibition of the MAPK/ERK phosphorylation pathway. Remarkably, we found that rescuing the expression of TRIM36 during anti-androgen therapy could improve the drug efficacy. Collectively, TRIM36 is a novel androgen-responsive gene, and it dramatically enhanced the efficacy of anti-androgen drugs against prostate cancer. PMID- 29449535 TI - Norisoboldine, a natural AhR agonist, promotes Treg differentiation and attenuates colitis via targeting glycolysis and subsequent NAD+/SIRT1/SUV39H1/H3K9me3 signaling pathway. AB - Norisoboldine (NOR), a natural aryl hydrocarbon receptor (AhR) agonist, has been demonstrated to attenuate ulcerative colitis (UC) and induce the generation of Treg cells. Under UC condition, hypoxia widely exists in colonic mucosa, and secondary changes of microRNAs (miRs) expressions and glycolysis contribute to Treg differentiation. At present, we worked for exploring the deep mechanisms for NOR-promoted Treg differentiation in hypoxia and its subsequent anti-UC action from the angle of AhR/miR or AhR/glycolysis axis. Results showed that NOR promoted Treg differentiation in hypoxia and the effect was stronger relative to normoxia. It activated AhR in CD4+ T cells under hypoxic microenvironment; CH223191 (a specific AhR antagonist) and siAhR-3 abolished NOR-promoted Treg differentiation. Furthermore, the progress of glycolysis, levels of Glut1 and HK2, and expression of miR-31 rather than miR-219 and miR-490 in CD4+ T cells were downregulated by NOR treatment under hypoxic microenvironment. However, HK2 plasmid but not miR-31 mimic significantly interfered NOR-enhanced Treg polarization. In addition, NOR reduced NAD+ and SIRT1 levels, facilitated the ubiquitin-proteasomal degradation of SUV39H1 protein, and inhibited the enrichment of H3K9me3 at -1, 201 to -1,500 region of Foxp3 promoter in CD4+ T cells under hypoxic microenvironment, which was weakened by HK2 plasmid, CH223191, and siAhR-3. Finally, the correlation between NOR-mediated activation of AhR, repression of glycolysis, regulation of NAD+/SIRT1/SUV39H1/H3K9me3 signals, induction of Treg cells, and remission of colitis was confirmed in mice with DSS-induced colitis by using CH223191 and HK2 plasmid. In conclusion, NOR promoted Treg differentiation and then alleviated the development of colitis by regulating AhR/glycolysis axis and subsequent NAD+/SIRT1/SUV39H1/H3K9me3 signaling pathway. PMID- 29449536 TI - Impaired autophagic flux is associated with the severity of trauma and the role of A2AR in brain cells after traumatic brain injury. AB - Recent studies have shown that after traumatic brain injury (TBI), the number of autophagosomes is markedly increased in brain cells surrounding the wound; however, whether autophagy is enhanced or suppressed by TBI remains controversial. In our study, we used a controlled cortical impact system to establish models of mild, moderate and severe TBI. In the mild TBI model, the levels of autophagy-related protein 6 (Beclin1) and autophagy-related protein 12 (ATG12)-autophagy-related protein 5 (ATG5) conjugates were increased, indicating the enhanced initiation of autophagy. Furthermore, the level of the autophagic substrate sequestosome 1 (SQSTM1) was decreased in the ipsilateral cortex. This result, together with the results observed in tandem mRFP-GFP-LC3 adeno associated virus (AAV)-infected mice, indicates that autophagosome clearance was also increased after mild TBI. Conversely, following moderate and severe TBI, there was no change in the initiation of autophagy, and autophagosome accumulation was observed. Next, we used chloroquine (CQ) to artificially impair autophagic flux in the injured cortex of the mild TBI model and found that the severity of trauma was obviously exacerbated. In addition, autophagic flux and trauma severity were significantly improved in adenosine A2A receptor (A2AR) knockout (KO) mice subjected to moderate TBI. Thus, A2AR may be involved in regulating the impairment of autophagic flux in response to brain injury. Our findings suggest that whether autophagy is increased after TBI is associated with whether autophagic flux is impaired, and the impairment of autophagic flux exacerbates the severity of trauma. Furthermore, A2AR may be a target for alleviating the impairment in autophagic flux after TBI. PMID- 29449537 TI - Predictive and preventive significance of AMPK activation on hepatocarcinogenesis in patients with liver cirrhosis. AB - Metformin has been demonstrated to prevent hepatocellular carcinoma (HCC). Metformin acts mainly by phosphorylation of AMPK. However, the phosphorylation status of AMPK and its role in the prediction and prevention of HCC in cirrhotic patients remains unclear. The phosphorylation status of AMPK (Thr172) was determined by immunostaining in tissue microarrays of 426 cirrhotic liver tissues. Low expression of p-AMPK was observed in 94 (22.1%) cases. The median follow-up time was 87 months. HCC occurrence probability at 1/3/5/10 years after Hassab procedure was 3.1/9.6/13.8/30.6% in patients with p-AMPK low expression and 0/0.3/0.3/8% in patients with p-AMPK high expression, respectively. HCC occurrence risk was significantly higher in patients with p-AMPK low expression in univariable analysis (HR, 6.25; 95% CI: 3.36-11.60; P < 0.001) and multivariable analysis (HR, 6.0; 95% CI: 3.24-11.10; P < 0.001). An independent external cohort validated the significance of p-AMPK low expression. In addition, in vivo experiments demonstrated that AMPK activation status was negatively related to HCC occurrence and blocking autophagy by chloroquine counteracted the protective effect of AMPK phosphorylation. These results present novel insight into a critical predictive role of AMPK activation in hepatocarcinogenesis and AMPK activation seems to be a potential target for the prevention of hepatocellular carcinoma in patients with liver cirrhosis. PMID- 29449538 TI - Downregulation of PERK activity and eIF2alpha serine 51 phosphorylation by mTOR complex 1 elicits pro-oxidant and pro-death effects in tuberous sclerosis deficient cells. AB - Oxidative stress determines cell fate through several mechanisms, among which regulation of mRNA translation by the phosphorylation of the alpha (alpha) subunit of the translation initiation factor eIF2alpha at serine 51 (eIF2alphaP) plays a prominent role. Increased eIF2alphaP can contribute to tumor progression as well as tumor suppression. While eIF2alphaP is increased in most cells to promote survival and adaptation to different forms of stress, we demonstrate that eIF2alphaP is reduced in tuberous sclerosis complex 2 (TSC2)-deficient cells subjected to oxidative insults. Decreased eIF2alphaP in TSC2-deficient cells depends on reactive oxygen species (ROS) production and is associated with a reduced activity of the endoplasmic reticulum (ER)-resident kinase PERK owing to the hyper-activation of the mammalian target of rapamycin complex 1 (mTORC1). Downregulation of PERK activity and eIF2alphaP is accompanied by increased ROS production and enhanced susceptibility of TSC2-deficient cells to extrinsic pro oxidant stress. The decreased levels of eIF2alphaP delay tumor formation of TSC2 deficient cells in immune deficient mice, an effect that is significantly alleviated in mice subjected to an anti-oxidant diet. Our findings reveal a previously unidentified connection between mTORC1 and eIF2alphaP in TSC2 deficient cells with potential implications in tumor suppression in response to oxidative insults. PMID- 29449539 TI - G9A promotes gastric cancer metastasis by upregulating ITGB3 in a SET domain independent manner. AB - Tumor metastasis is the leading cause of death in patients with advanced gastric cancer (GC). Limited therapeutic regimens are available for this condition, which is associated with a poor prognosis, and the mechanisms underlying tumor metastasis remain unclear. In the present study, increased histone methyltransferase G9A expression in GC tissues correlated with advanced stage and shorter overall survival, and in vitro and in vivo experiments revealed that G9A promoted tumor invasion and metastasis. Moreover, we observed that Reg IV induced G9A via the p-ERK/p-SP1 pathway. SP1 directly binds the G9A promoter and enhances G9A expression, and upregulated G9A then forms a transcriptional activator complex with P300 and GR, thereby promoting ITGB3 expression induced by dexamethasone (DEX) and contributing to GC metastasis. However, the G9A-mediated increase in ITGB3 expression was not dependent on the SET domain and methyltransferase activity of G9A. This study demonstrates that G9A is an independent prognostic marker and promotes metastasis in GC, thus suggesting that it may be a tumor biomarker and potential therapeutic target in GC. PMID- 29449540 TI - S100A4 promotes lung tumor development through beta-catenin pathway-mediated autophagy inhibition. AB - Autophagy has emerged as a critical pathway in tumor development. S100A4 plays important roles in tumor metastasis, but its role in regulating autophagy has not been well characterized. In this study, we found that S100A4 was significantly upregulated in lung adenocarcinoma tissues. Clinical investigation demonstrated that high expression level of S100A4 was associated with tumor size and advanced tumor grades of lung adenocarcinoma patients. Moreover, our results revealed that extracellular S100A4 or overexpression of S100A4 inhibited starvation-induced autophagy and promoted cell proliferation in lung cancer cells in vitro; whereas small interfering RNA (siRNA)-mediated suppression of S100A4 increased autophagy and reduced cell viability in both A549 and LLC cells. Additionally, S100A4 inhibited starvation-induced autophagy to promote tumor cell viability via the Wnt pathway. Increased expression of beta-catenin consistently led to a decreased LC3-II protein abundance. Further, the inhibitory effect of S100A4 on autophagy and its promotion role in cell proliferation was abolished in A549 and LLC cells using the receptor for advanced glycation end products (RAGE)-specific inhibitor (FPS-ZM1). S100A4-deficient mice showed retarded tumor development. This effect was well correlated with increased expression of autophagy markers. Our findings demonstrate that S100A4 promotes lung tumor development through inhibiting autophagy in a beta-catenin signaling and S100A4 receptor RAGE-dependent manner, which provides a novel mechanism of S100A4-associated promotion of tumor development. PMID- 29449541 TI - Long noncoding RNA MEG3 suppresses liver cancer cells growth through inhibiting beta-catenin by activating PKM2 and inactivating PTEN. AB - Maternally expressed gene 3 (MEG3) encodes an lncRNA which is suggested to function as a tumor suppressor and has been showed to involve in a variety of cancers. Herein, our findings demonstrate that MEG3 inhibits the malignant progression of liver cancer cells in vitro and in vivo. Mechanistically, MEG3 promotes the expression and maturition of miR122 which targets PKM2. Therefore, MEG3 decreases the expression and nuclear location of PKM2 dependent on miR122. Furthermore, MEG3 also inhibits CyclinD1 and C-Myc via PKM2 in liver cancer cells. On the other hand, MEG3 promotes beta-catenin degradation through ubiquitin-proteasome system dependent on PTEN. Strikingly, MEG3 inhibits beta catenin activity through PKM2 reduction and PTEN increase. Significantly, we also found that excessive beta-catenin abrogated the effect of MEG3 in liver cancer. In conclusion, our study for the first time demonstrates that MEG3 acts as a tumor suppressor by negatively regulating the activity of the PKM2 and beta catenin signaling pathway in hepatocarcinogenesis and could provide potential therapeutic targets for the treatment of liver cancer.

AB - Stroke is one of the leading causes of mortality and disability worldwide. Uncovering the cellular and molecular pathophysiological processes in stroke have been a top priority. Long non-coding (lnc) RNAs play critical roles in different kinds of diseases. In recent years, a bulk of aberrantly expressed lncRNAs have been screened out in ischemic stroke patients or ischemia insulted animals using new technologies such as RNA-seq, deep sequencing, and microarrays. Nine specific lncRNAs, antisense non-coding RNA in the INK4 locus (ANRIL), metastasis-associate lung adenocarcinoma transcript 1 (MALAT1), N1LR, maternally expressed gene 3 (MEG3), H19, CaMK2D-associated transcript 1 (C2dat1), Fos downstream transcript (FosDT), small nucleolar RNA host gene 14 (SNHG14), and taurine-upregulated gene 1 (TUG1), were found increased in cerebral ischemic animals and/or oxygen-glucose deprived (OGD) cells. These lncRNAs were suggested to promote cell apoptosis, angiogenesis, inflammation, and cell death. Our Gene Ontology (GO) enrichment analysis predicted that MEG3, H19, and MALAT1 might also be related to functions such as neurogenesis, angiogenesis, and inflammation through mechanisms of gene regulation (DNA transcription, RNA folding, methylation, and gene imprinting). This knowledge may provide a better understanding of the functions and mechanisms of lncRNAs in ischemic stroke. Further elucidating the functions and mechanisms of these lncRNAs in biological systems under normal and pathological conditions may lead to opportunities for identifying biomarkers and novel therapeutic targets of ischemic stroke. PMID- 29449544 TI - PEAK1, acting as a tumor promoter in colorectal cancer, is regulated by the EGFR/KRas signaling axis and miR-181d. AB - PEAK1 is upregulated in multiple human malignancies and has been associated with tumor invasion and metastasis, but little is known about the role of PEAK1 in colorectal cancer (CRC) progression. We investigated the expression pattern, function and regulatory mechanisms of PEAK1 in CRC. Here, we found that PEAK1 is overexpressed in CRC tissues and that high PEAK1 expression predicts poor survival in colon cancer but not rectal cancer. Functionally, silencing PEAK1 inhibits cell proliferation, migration, and invasion in vitro and inhibits the growth of tumor xenografts in nude mice. Mechanistic studies revealed that PEAK1 is induced by epidermal growth factor receptor (EGFR) signaling and that PEAK1 is required for KRas-induced CRC cell growth and metastasis. Furthermore, we demonstrated that miR-181d directly targets PEAK1. Ectopic expression of miR-181d reduces the expression of PEAK1 and inhibits the growth and metastasis of CRC cells in vitro. Clinically, miR-181d is downregulated in CRC samples, and low miR 181d is correlated with poor patient survival. Our study demonstrates the importance of PEAK1 in CRC progression and suggests a potential mechanism by which increasing PEAK1 expression in CRC might be the result of EGFR/KRas signal activation and consequent miR-181d repression. PMID- 29449545 TI - Transcriptional repression of DNA repair genes is a hallmark and a cause of cellular senescence. AB - Cellular senescence response is (i) activated by numerous stresses, (ii) is characterized by a stable proliferation arrest, and (iii) by a set of specific features. Timely regulated senescence is thought to be beneficial, whereas chronic senescence such as during normal or premature aging is deleterious as it favors most, if not all, age-related diseases. In this study, using in-house or publicly available microarray analyses of transcriptomes of senescent cells, as well as analyses of the level of expression of several DNA repair genes by RT qPCR and immunoblot, we show that repression of DNA repair gene expression is associated with cellular senescence. This repression is mediated by the RB/E2F pathway and it may play a causal role in senescence induction, as single DNA repair gene repression by siRNA induced features of premature senescence. Importantly, activating RB independently of direct DNA damage also results in repression of DNA repair genes and in the subsequent induction of DNA damage and senescence. The dogma is that DNA damage observed during cellular senescence is directly provoked by DNA lesions following genotoxic attack (UV, IR, and ROS) or by induction of replicative stress upon oncogenic activation. Our in vitro results support a largely unsuspected contribution of the loss of DNA repair gene expression in the induction and the accumulation of the DNA damage observed in most, if not all, kinds of cellular senescence, and thus in the induction of cellular senescence. Further demonstration using in vivo models will help to generalize our findings. PMID- 29449546 TI - A community approach to mortality prediction in sepsis via gene expression analysis. AB - Improved risk stratification and prognosis prediction in sepsis is a critical unmet need. Clinical severity scores and available assays such as blood lactate reflect global illness severity with suboptimal performance, and do not specifically reveal the underlying dysregulation of sepsis. Here, we present prognostic models for 30-day mortality generated independently by three scientific groups by using 12 discovery cohorts containing transcriptomic data collected from primarily community-onset sepsis patients. Predictive performance is validated in five cohorts of community-onset sepsis patients in which the models show summary AUROCs ranging from 0.765-0.89. Similar performance is observed in four cohorts of hospital-acquired sepsis. Combining the new gene expression-based prognostic models with prior clinical severity scores leads to significant improvement in prediction of 30-day mortality as measured via AUROC and net reclassification improvement index These models provide an opportunity to develop molecular bedside tests that may improve risk stratification and mortality prediction in patients with sepsis. PMID- 29449547 TI - Inference of field reversed configuration topology and dynamics during Alfvenic transients. AB - Active control of field reversed configuration (FRC) devices requires a method to determine the flux surface geometry and dynamic properties of the plasma during both transient and steady-state conditions. The current tomography (CT) method uses Bayesian inference to determine the plasma current density distribution using both the information from magnetic measurements and a physics model in the prior. Here we show that, from the inferred current sources, the FRC topology and its axial stability properties are readily obtained. When Gaussian process priors are used and the forward model is linear, the CT solution involves non-iterative matrix operations and is then ideally suited for deterministic real-time applications. Because no equilibrium assumptions are used in this case, inference of plasma topology and dynamics up to Alfvenic frequencies then becomes possible. Inference results for the C-2U device exhibit self-consistency of motions and forces during Alfvenic transients, as well as good agreement with plasma imaging diagnostics.

PMID- 29449553 TI - Nuclear factor 90 promotes angiogenesis by regulating HIF-1alpha/VEGF-A expression through the PI3K/Akt signaling pathway in human cervical cancer. AB - Vascular endothelial growth factor A (VEGF-A), a fundamental component of angiogenesis, provides nutrients and oxygen to solid tumors, and enhances tumor cell survival, invasion, and migration. Nuclear factor 90 (NF90), a double stranded RNA-binding protein, is strongly expressed in several human cancers, promotes tumor growth by reducing apoptosis, and increasing cell cycle process. The mechanisms by which cervical cancer cells inducing VEGF-A expression and angiogenesis upon NF90 upregulation remain to be fully established. We demonstrated that NF90 is upregulated in human cervical cancer specimens and the expression of NF90 is paralleled with that of VEGF-A under hypoxia. The expressions of hypoxia inducible factor-1alpha (HIF-1alpha) and VEGF-A are downregulated upon NF90 knockdown, which can be rescued by ectopic expression of NF90. Suppression of NF90 decreases the tube formation and cell migration of HUVECs. Moreover, the PI3K/Akt signaling pathway participates in the regulation. Knockdown of NF90 also reduces the tumor growth and angiogenesis of cervical cancer cell line in the mouse xenograft model. Taken together, suppression of NF90 in cervical cancer cell lines can decrease VEGF-A expression, inhibit angiogenesis, and reduce tumorigenic capacity in vivo. PMID- 29449551 TI - Mutations in CFAP43 and CFAP44 cause male infertility and flagellum defects in Trypanosoma and human. AB - Spermatogenesis defects concern millions of men worldwide, yet the vast majority remains undiagnosed. Here we report men with primary infertility due to multiple morphological abnormalities of the sperm flagella with severe disorganization of the sperm axoneme, a microtubule-based structure highly conserved throughout evolution. Whole-exome sequencing was performed on 78 patients allowing the identification of 22 men with bi-allelic mutations in DNAH1 (n = 6), CFAP43 (n = 10), and CFAP44 (n = 6). CRISPR/Cas9 created homozygous CFAP43/44 male mice that were infertile and presented severe flagellar defects confirming the human genetic results. Immunoelectron and stimulated-emission-depletion microscopy performed on CFAP43 and CFAP44 orthologs in Trypanosoma brucei evidenced that both proteins are located between the doublet microtubules 5 and 6 and the paraflagellar rod. Overall, we demonstrate that CFAP43 and CFAP44 have a similar structure with a unique axonemal localization and are necessary to produce functional flagella in species ranging from Trypanosoma to human. PMID- 29449555 TI - Intravenous injections of the oncolytic virus M1 as a novel therapy for muscle invasive bladder cancer. AB - Muscle-invasive bladder cancer (MIBC) is associated with low survival and high recurrence rates even in cases in which patients receive systemic treatments, such as surgery and chemotherapy. Here, we found that a naturally existing alphavirus, namely, M1, selectively kills bladder cancer cells but not normal cells, findings supported by our observations of changes in viral replication and MIBC and patient-derived MIBC cell apoptosis. Transcriptome analysis revealed that interferon-stimulated genes (ISGs) are expressed at low levels in sensitive bladder cancer cells and high levels in resistant cells. Knocking down ZC3HAV1 (ZAP), an antiviral factor in ISGs, restores M1 virus reactivity in resistant cells, and overexpressing ZAP partially reverses M1 virus-induced decreases in cell viability in sensitive cells. In orthotopic MIBC mice, tail vein injections of M1 significant inhibit tumor growth and prolong survival period, antitumor effects of M1 are stronger than those of the first-line chemotherapy agent cisplatin (CDDP). Treated tumors display enhanced cleaved-caspase-3 signals, which are representative of cell apoptosis, and decreased Ki-67 signals, which are representative of cell proliferation. Moreover, tissue microarray (TMA) analyses of clinical tumor specimens revealed that up to 45.6% of cases of MIBC presented with low ZAP expression, a finding that is prevalent in advanced MIBC. Our results indicate that the oncolytic virus M1 is a novel agent capable of functioning as a precise and effective therapy for MIBC. PMID- 29449554 TI - Dynamic allocation of orthogonal ribosomes facilitates uncoupling of co-expressed genes. AB - Introduction of synthetic circuits into microbes creates competition between circuit and host genes for shared cellular resources, such as ribosomes. This can lead to the emergence of unwanted coupling between the expression of different circuit genes, complicating the design process and potentially leading to circuit failure. By expressing a synthetic 16S rRNA with altered specificity, we can partition the ribosome pool into host-specific and circuit-specific activities. We show mathematically and experimentally that the effects of resource competition can be alleviated by targeting genes to different ribosomal pools. This division of labour can be used to increase flux through a metabolic pathway. We develop a model of cell physiology which is able to capture these observations and use it to design a dynamic resource allocation controller. When implemented, this controller acts to decouple genes by increasing orthogonal ribosome production as the demand for translational resources by a synthetic circuit increases. PMID- 29449556 TI - CD1d-dependent immune suppression mediated by regulatory B cells through modulations of iNKT cells. AB - Regulatory B cells (Breg) express high levels of CD1d that presents lipid antigens to invariant natural killer T (iNKT) cells. The function of CD1d in Breg biology and iNKT cell activity during inflammation remains unclear. Here we show, using chimeric mice, cell depletion and adoptive cell transfer, that CD1d-lipid presentation by Bregs induces iNKT cells to secrete interferon (IFN)-gamma to contribute, partially, to the downregulation of T helper (Th)1 and Th17-adaptive immune responses and ameliorate experimental arthritis. Mice lacking CD1d expressing B cells develop exacerbated disease compared to wild-type mice, and fail to respond to treatment with the prototypical iNKT cell agonist alpha galactosylceramide. The absence of lipid presentation by B cells alters iNKT cell activation with disruption of metabolism regulation and cytokine responses. Thus, we identify a mechanism by which Bregs restrain excessive inflammation via lipid presentation. PMID- 29449558 TI - Interventions to enhance the adoption of asthma self-management behaviour in the South Asian and African American population: a systematic review. AB - South Asian and other minority communities suffer poorer asthma outcomes, have a higher rate of unscheduled care and benefit less from most existing self management interventions when compared to the majority population. Possible reasons for these differences include failure to implement asthma self-management strategies, or that strategies implemented were inappropriate for their needs; alternatively, they may relate to the minority and/or lower socioeconomic status of these populations. We aimed to synthesise evidence from randomised controlled trials for asthma self-management in South Asian and Black populations from different sociocultural contexts, and identify barriers and facilitators to implementing self-management. We systematically searched eight electronic databases, and research registers, and manually searched relevant journals and reference lists of reviews. Seventeen trials met the inclusion criteria and were analysed narratively. We found two culturally targeted interventions compared to fifteen culturally modified interventions. Interventions used diverse self management strategies; education formed a central component. Interventions in South Asian and African-American minority communities were less effective than interventions delivered in indigenous populations in South Asia, though the latter trials were at higher risk of bias. Education, with continuous professional support, was common to most interventions. Facilitators to asthma self-management included: ensuring culturally/linguistically appropriate education, adapting to learning styles, addressing daily stressors/social support and generic self-management strategies. In conclusion, when developing and evaluating self-management interventions aimed at different cultures, the influence of sociocultural contexts (including whether patients are from a minority or indigenous population) can be important for the conceptualisation of culture and customisation of self-management strategies. PMID- 29449557 TI - Differential patterns of contextual organization of memory in first-episode psychosis. AB - Contextual information is used to support and organize episodic memory. Prior research has reliably shown memory deficits in psychosis; however, little research has characterized how this population uses contextual information during memory recall. We employed an approach founded in a computational framework of free recall to quantify how individuals with first episode of psychosis (FEP, N = 97) and controls (CON, N = 55) use temporal and semantic context to organize memory recall. Free recall was characterized using the Hopkins Verbal Learning Test-Revised (HVLT-R). We compared FEP and CON on three measures of free recall: proportion recalled, temporal clustering, and semantic clustering. Measures of temporal/semantic clustering quantified how individuals use contextual information to organize memory recall. We also assessed to what extent these measures relate to antipsychotic use and differentiated between different types of psychosis. We also explored the relationship between these measures and intelligence. In comparison to CON, FEP had reduced recall and less temporal clustering during free recall (p < 0.05, Bonferroni-corrected), and showed a trend towards greater semantic clustering (p = 0.10, Bonferroni-corrected). Within FEP, antipsychotic use and diagnoses did not differentiate between free recall accuracy or contextual organization of memory. IQ was related to free recall accuracy, but not the use of contextual information during recall in either group (p < 0.05, Bonferroni-corrected). These results show that in addition to deficits in memory recall, FEP differed in how they organize memories compared to CON. PMID- 29449559 TI - Downregulation of SREBP inhibits tumor growth and initiation by altering cellular metabolism in colon cancer. AB - Sterol regulatory element-binding proteins (SREBPs) belong to a family of transcription factors that regulate the expression of genes required for the synthesis of fatty acids and cholesterol. Three SREBP isoforms, SREBP1a, SREBP1c, and SREBP2, have been identified in mammalian cells. SREBP1a and SREBP1c are derived from a single gene through the use of alternative transcription start sites. Here we investigated the role of SREBP-mediated lipogenesis in regulating tumor growth and initiation in colon cancer. Knockdown of either SREBP1 or SREBP2 decreased levels of fatty acids as a result of decreased expression of SREBP target genes required for lipid biosynthesis in colon cancer cells. Bioenergetic analysis revealed that silencing SREBP1 or SREBP2 expression reduced the mitochondrial respiration, glycolysis, as well as fatty acid oxidation indicating an alteration in cellular metabolism. Consequently, the rate of cell proliferation and the ability of cancer cells to form tumor spheroids in suspension culture were significantly decreased. Similar results were obtained in colon cancer cells in which the proteolytic activation of SREBP was blocked. Importantly, knockdown of either SREBP1 or SREBP2 inhibited xenograft tumor growth in vivo and decreased the expression of genes associated with cancer stem cells. Taken together, our findings establish the molecular basis of SREBP dependent metabolic regulation and provide a rationale for targeting lipid biosynthesis as a promising approach in colon cancer treatment. PMID- 29449560 TI - Knockout of zebrafish interleukin 7 receptor (IL7R) by the CRISPR/Cas9 system delays retinal neurodevelopment. AB - Interleukin 7 receptor (il7r), a transmembrane receptor, belongs to the type I cytokine receptor family. Il7r is involved in the pathogenesis of neurodegenerative disorders, such as multiple sclerosis. Targeted knockdown of il7r leads to delayed myelination, highlighting the potential role of il7r in the development of the nervous system. Zebrafish is an ideal model for the study of neurogenesis; moreover, the il7r gene is highly conserved between zebrafish and human. The aim of the present study was to investigate the novel function of il7r in neurogenesis. First, an il7r -/- homozygous mutant line was generated by clustered regularly interspaced short palindromic repeats (CRISPR)-associated 9 (CRISPR/Cas9) technology. Second, the gross development of il7r-/- mutants revealed remarkably smaller eyes and delayed retinal neurodifferentiation. Third, microarray analysis revealed that genes associated with the phototransduction signalling pathway were strongly down-regulated in il7r -/- mutants. Finally, the results from behavioural tests indicated that visual function was impaired in il7r -/- mutant larvae. Overall, our data demonstrate that a lack of il7r retards the development of the retina. Thus, il7r is an essential molecule for maintaining normal retinal development in zebrafish. PMID- 29449548 TI - Common surgical procedures in pilonidal sinus disease: A meta-analysis, merged data analysis, and comprehensive study on recurrence. AB - We systematically searched available databases. We reviewed 6,143 studies published from 1833 to 2017. Reports in English, French, German, Italian, and Spanish were considered, as were publications in other languages if definitive treatment and recurrence at specific follow-up times were described in an English abstract. We assessed data in the manner of a meta-analysis of RCTs; further we assessed non-RCTs in the manner of a merged data analysis. In the RCT analysis including 11,730 patients, Limberg & Dufourmentel operations were associated with low recurrence of 0.6% (95%CI 0.3-0.9%) 12 months and 1.8% (95%CI 1.1-2.4%) respectively 24 months postoperatively. Analysing 89,583 patients from RCTs and non-RCTs, the Karydakis & Bascom approaches were associated with recurrence of only 0.2% (95%CI 0.1-0.3%) 12 months and 0.6% (95%CI 0.5-0.8%) 24 months postoperatively. Primary midline closure exhibited long-term recurrence up to 67.9% (95%CI 53.3-82.4%) 240 months post-surgery. For most procedures, only a few RCTs without long term follow up data exist, but substitute data from numerous non-RCTs are available. Recurrence in PSD is highly dependent on surgical procedure and by follow-up time; both must be considered when drawing conclusions regarding the efficacy of a procedure. PMID- 29449561 TI - Discovery of a magnetic conductive interface in PbZr0.2Ti0.8O3 /SrTiO3 heterostructures. AB - Emergent physical properties often arise at interfaces of complex oxide heterostructures due to the interplay between various degrees of freedom, especially those with polar discontinuities. It is desirable to explore if these structures may generate pure and controllable spin currents, which are needed to attain unmatched performance and energy efficiency in the next-generation spintronic devices. Here we report the emergence of a spin-polarized two dimensional electron gas (SP-2DEG) at the interface of two insulators, SrTiO3 and PbZr0.2Ti0.8O3. This SP-2DEG is strongly localized at the interfacial Ti atoms, due to the interplay between Coulomb interaction and band bending, and can be tuned by the ferroelectric polarization. Our findings open a door for engineering ferroelectric/insulator interfaces to create tunable ferroic orders for magnetoelectric device applications and provide opportunities for designing multiferroic materials in heterostructures. PMID- 29449562 TI - Chir99021 and Valproic acid reduce the proliferative advantage of Apc mutant cells. AB - More than 90% of colorectal cancers carry mutations in Apc that drive tumourigenesis. A 'just-right' signalling model proposes that Apc mutations stimulate optimal, but not excessive Wnt signalling, resulting in a growth advantage of Apc mutant over wild-type cells. Reversal of this growth advantage constitutes a potential therapeutic approach. We utilised intestinal organoids to compare the growth of Apc mutant and wild-type cells. Organoids derived from Apc Min/+ mice recapitulate stages of intestinal polyposis in culture. They eventually form spherical cysts that reflect the competitive growth advantage of cells that have undergone loss of heterozygosity (LOH). We discovered that this emergence of cysts was inhibited by Chiron99021 and Valproic acid, which potentiates Wnt signalling. Chiron99021 and Valproic acid restrict the growth advantage of Apc mutant cells while stimulating that of wild-type cells, suggesting that excessive Wnt signalling reduces the relative fitness of Apc mutant cells. As a proof of concept, we demonstrated that Chiron99021-treated Apc mutant organoids were rendered susceptible to TSA-induced apoptosis, while wild type cells were protected. PMID- 29449564 TI - Aggregation-fragmentation and individual dynamics of active clusters. AB - A remarkable feature of active matter is the propensity to self-organize. One striking instance of this ability to generate spatial structures is the cluster phase, where clusters broadly distributed in size constantly move and evolve through particle exchange, breaking or merging. Here we propose an exhaustive description of the cluster dynamics in apolar active matter. Exploiting large statistics gathered on thousands of Janus colloids, we measure the aggregation and fragmentation rates and rationalize the resulting cluster size distribution and fluctuations. We also show that the motion of individual clusters is entirely consistent with a model positing random orientation of colloids. Our findings establish a simple, generic model of cluster phase, and pave the way for a thorough understanding of clustering in active matter. PMID- 29449563 TI - Cinacalcet-mediated activation of the CaMKKbeta-LKB1-AMPK pathway attenuates diabetic nephropathy in db/db mice by modulation of apoptosis and autophagy. AB - Apoptosis and autophagy are harmoniously regulated biological processes for maintaining tissue homeostasis. AMP-activated protein kinase (AMPK) functions as a metabolic sensor to coordinate cellular survival and function in various organs, including the kidney. We investigated the renoprotective effects of cinacalcet in high-glucose treated human glomerular endothelial cells (HGECs), murine podocytes and C57BLKS/J-db/db mice. In cultured HGECs and podocytes, cinacalcet decreased oxidative stress and apoptosis and increased autophagy that were attributed to the increment of intracellular Ca2+ concentration and the phosphorylation of Ca2+/calmodulin-dependent protein kinase kinasebeta (CaMKKbeta)-Liver kinase B1 (LKB1)-AMPK and their downstream signals including the phosphorylation of endothelial nitric oxide synthase (eNOS) and increases in superoxide dismutases and B cell leukemia/lymphoma 2/BCL-2-associated X protein expression. Interestingly, intracellular chelator BAPTA-AM reversed cinacalcet induced CaMKKbeta elevation and LKB1 phosphorylation. Cinacalcet reduced albuminuria without influencing either blood glucose or Ca2+ concentration and ameliorated diabetes-induced renal damage, which were related to the increased expression of calcium-sensing receptor and the phosphorylation of CaMKKbeta-LKB1. Subsequent activation of AMPK was followed by the activation of peroxisome proliferator-activated receptor gamma coactivator-1alpha and phospho-Ser1177eNOS nitric oxide, resulting in a decrease in apoptosis and oxidative stress as well as an increase in autophagy.Our results suggest that cinacalcet increases intracellular Ca2+ followed by an activation of CaMKKbeta-LKB1-AMPK signaling in GECs and podocytes in the kidney, which provides a novel therapeutic means for type 2 diabetic nephropathy by modulation of apoptosis and autophagy. PMID- 29449566 TI - First evidence of an extensive Acheulean large cutting tool accumulation in Europe from Porto Maior (Galicia, Spain). AB - We describe a European Acheulean site characterised by an extensive accumulation of large cutting tools (LCT). This type of Lower Paleolithic assemblage, with dense LCT accumulations, has only been found on the African continent and in the Near East until now. The identification of a site with large accumulations of LCTs favours the hypothesis of an African origin for the Acheulean of Southwest Europe. The lithic tool-bearing deposits date back to 293-205 thousand years ago. Our chronological findings confirm temporal overlap between sites with clear "African" Acheulean affinities and Early Middle Paleolithic sites found elsewhere in the region. These complex technological patterns could be consistent with the potential coexistence of different human species in south-western Europe during the Middle Pleistocene. PMID- 29449565 TI - Amphibian chytridiomycosis outbreak dynamics are linked with host skin bacterial community structure. AB - Host-associated microbes are vital for combatting infections and maintaining health. In amphibians, certain skin-associated bacteria inhibit the fungal pathogen Batrachochytrium dendrobatidis (Bd), yet our understanding of host microbial ecology and its role in disease outbreaks is limited. We sampled skin associated bacteria and Bd from Pyrenean midwife toad populations exhibiting enzootic or epizootic disease dynamics. We demonstrate that bacterial communities differ between life stages with few shared taxa, indicative of restructuring at metamorphosis. We detected a significant effect of infection history on metamorph skin microbiota, with reduced bacterial diversity in epizootic populations and differences in community structure and predicted function. Genome sequencing of Bd isolates supports a single introduction to the Pyrenees and reveals no association between pathogen genetics and epidemiological trends. Our findings provide an ecologically relevant insight into the microbial ecology of amphibian skin and highlight the relative importance of host microbiota and pathogen genetics in predicting disease outcome. PMID- 29449567 TI - Systematic analysis of protein turnover in primary cells. AB - A better understanding of proteostasis in health and disease requires robust methods to determine protein half-lives. Here we improve the precision and accuracy of peptide ion intensity-based quantification, enabling more accurate protein turnover determination in non-dividing cells by dynamic SILAC-based proteomics. This approach allows exact determination of protein half-lives ranging from 10 to >1000 h. We identified 4000-6000 proteins in several non dividing cell types, corresponding to 9699 unique protein identifications over the entire data set. We observed similar protein half-lives in B-cells, natural killer cells and monocytes, whereas hepatocytes and mouse embryonic neurons show substantial differences. Our data set extends and statistically validates the previous observation that subunits of protein complexes tend to have coherent turnover. Moreover, analysis of different proteasome and nuclear pore complex assemblies suggests that their turnover rate is architecture dependent. These results illustrate that our approach allows investigating protein turnover and its implications in various cell types. PMID- 29449568 TI - Binge Alcohol Exposure Causes Neurobehavioral Deficits and GSK3beta Activation in the Hippocampus of Adolescent Rats. AB - Heavy alcohol exposure causes profound damage to the adolescent brain, particularly the hippocampus, which underlie some behavioral deficits. However, the underlying molecular mechanisms remain inconclusive. The current study sought to determine whether binge alcohol exposure affects the hippocampus-related behaviors and key signaling proteins that may mediate alcohol neurotoxicity in adolescent rats. Alcohol exposure reduced the number of both NeuN-positive and doublecortin-positive cells in the hippocampus. Alcohol also induced neurodegeneration which was confirmed by ultrastructural analysis by electronic microscopy and was accompanied with the activation of microglia. Binge alcohol exposure impaired spatial learning and memory which was evaluated by the Morris water maze. However, alcohol did not alter the spontaneous locomotor activity which was determined by the open field test. GSK3beta is a multi-function serine/threonine protein kinase regulating both neuronal survival and neurogenesis and plays an important role in various neurodegenerative disorders. We have previously shown that GSK3beta is a key mediator of alcohol-induced neuron apoptosis in the developing brain. We showed here binge alcohol exposure caused GSK3beta activation by inducing dephosphorylation at Ser9 without affecting the phosphorylation of Tyr216 in the hippocampus. Thus, GSK3beta may be involved in binge alcohol exposure-induced neuronal damage to the adolescent hippocampus. PMID- 29449569 TI - Threshold driven contagion on weighted networks. AB - Weighted networks capture the structure of complex systems where interaction strength is meaningful. This information is essential to a large number of processes, such as threshold dynamics, where link weights reflect the amount of influence that neighbours have in determining a node's behaviour. Despite describing numerous cascading phenomena, such as neural firing or social contagion, the modelling of threshold dynamics on weighted networks has been largely overlooked. We fill this gap by studying a dynamical threshold model over synthetic and real weighted networks with numerical and analytical tools. We show that the time of cascade emergence depends non-monotonously on weight heterogeneities, which accelerate or decelerate the dynamics, and lead to non trivial parameter spaces for various networks and weight distributions. Our methodology applies to arbitrary binary state processes and link properties, and may prove instrumental in understanding the role of edge heterogeneities in various natural and social phenomena. PMID- 29449570 TI - In-situ visualization of sound-induced otolith motion using hard X-ray phase contrast imaging. AB - Regarding the basics of ear structure-function relationships in fish, the actual motion of the solid otolith relative to the underlying sensory epithelium has rarely been investigated. Otolith motion has been characterized based on a few experimental studies and on approaches using mathematical modeling, which have yielded partially conflicting results. Those studies either predicted a simple back-and-forth motion of the otolith or a shape-dependent, more complex motion. Our study was designed to develop and test a new set-up to generate experimental data on fish otolith motion in-situ. Investigating the basic parameters of otolith motion requires an approach with high spatial and temporal resolution. We therefore used hard X-ray phase contrast imaging (XPCI). We compared two anatomically well-studied cichlid species, Steatocranus tinanti and Etroplus maculatus, which, among other features, differ in the 3D shape of their otoliths. In a water-filled tank, we presented a pure tone of 200 Hz to 1) isolated otoliths embedded in agarose serving as a simple model or 2) to a fish (otoliths in-situ). Our new set-up successfully visualized the motion of otoliths in-situ and therefore paves the way for future studies evaluating the principles of otolith motion. PMID- 29449571 TI - An in silico argument for mitochondrial microRNA as a determinant of primary non function in liver transplantation. AB - Mitochondria have their own genomic, transcriptomic and proteomic machinery but are unable to be autonomous, needing both nuclear and mitochondrial genomes. The aim of this work was to use computational biology to explore the involvement of Mitochondrial microRNAs (MitomiRs) and their interactions with the mitochondrial proteome in a clinical model of primary non function (PNF) of the donor after cardiac death (DCD) liver. Archival array data on the differential expression of miRNA in DCD PNF was re-analyzed using a number of publically available computational algorithms. 10 MitomiRs were identified of importance in DCD PNF, 7 with predicted interaction of their seed sequence with the mitochondrial transcriptome that included both coding, and non coding areas of the hypervariability region 1 (HVR1) and control region. Considering miRNA regulation of the nuclear encoded mitochondrial proteome, 7 hypothetical small proteins were identified with homolog function that ranged from co-factor for formation of ATP Synthase, REDOX balance and an importin/exportin protein. In silico, unconventional seed interactions, both non canonical and alternative seed sites, appear to be of greater importance in MitomiR regulation of the mitochondrial genome. Additionally, a number of novel small proteins of relevance in transplantation have been identified which need further characterization. PMID- 29449572 TI - Optimising the decellularization of human elastic cartilage with trypsin for future use in ear reconstruction. AB - Decellularized scaffolds can induce chondrogenic differentiation of stem cells. This study compares different methods to optimise the decellularization of auricular cartilage. The process consisted of an initial 12 hour dry freeze thaw which froze the cartilage specimens in an empty tube at -20 degrees C. Samples were allowed to thaw at room temperature followed by submersion in phosphate buffer solution in which they were frozen at -20 degrees C for a 12 hour period. They were then allowed to thaw at room temperature as before. Protocol A subsequently involved subjecting specimens to both deoxyribonuclease and sodium deoxycholate. Protocol B and C were adaptations of this using 0.25% trypsin (7 cycles) and a 0.5 molar solution of ethylenediaminetetraacetic acid (3 hours for each cycle) respectively as additional steps. Trypsin accelerated the decellularization process with a reduction in DNA content from 55.4 ng/MUL (native) to 17.3 ng/MUL (P-value < 0.05) after 14 days. Protocol B showed a faster reduction in DNA content when compared with protocol A. In comparison to protocol C after 14 days, trypsin also showed greater decellularization with a mean difference of 11.7 ng/MUL (P-value < 0.05). Histological analysis with H&E and DAPI confirmed depletion of cells at 14 days with trypsin. PMID- 29449573 TI - Nuclear targeting of the betanodavirus B1 protein via two arginine-rich domains induces G1/S cell cycle arrest mediated by upregulation of p53/p21. AB - The molecular functions of betanodavirus non-structural protein B and its role in host cell survival remain unclear. In the present study, we examined the roles of specific nuclear targeting domains in B1 localization as well as the effect of B1 nuclear localization on the cell cycle and host cell survival. The B1 protein of the Red spotted grouper nervous necrosis virus (RGNNV) was detected in GF-1 grouper cells as early as 24 hours post-infection (hpi). Using an EYFP-B1 fusion construct, we observed nuclear localization of the B1 protein (up to 99%) in GF-1 cells at 48 hpi. The nuclear localization of B1 was mediated by two arginine-rich nuclear targeting domains (B domain: 46RRSRR51; C domain: 63RDKRPRR70) and domain C was more important than domain B in this process. B1 nuclear localization correlated with upregulation of p53 and p21(wef1/cip1); downregulation of Cyclin D1, CDK4 and Mdm2; and G1/S cell cycle arrest in GF-1 cells. In conclusion, nuclear targeting of the RGNNV B1 protein via two targeting domains causes cell cycle arrest by up-regulating p53/p21 and down-regulating Mdm2, thereby regulating host cell survival. PMID- 29449574 TI - Upregulation of FOXM1 in a subset of relapsed myeloma results in poor outcome. PMID- 29449576 TI - Lizards ran bipedally 110 million years ago. AB - Four heteropod lizard trackways discovered in the Hasandong Formation (Aptian early Albian), South Korea assigned to Sauripes hadongensis, n. ichnogen., n. ichnosp., which represents the oldest lizard tracks in the world. Most tracks are pes tracks (N = 25) that are very small, average 22.29 mm long and 12.46 mm wide. The pes tracks show "typical" lizard morphology as having curved digit imprints that progressively increase in length from digits I to IV, a smaller digit V that is separated from the other digits by a large interdigital angle. The manus track is 19.18 mm long and 19.23 mm wide, and shows a different morphology from the pes. The predominant pes tracks, the long stride length of pes, narrow trackway width, digitigrade manus and pes prints, and anteriorly oriented long axis of the fourth pedal digit indicate that these trackways were made by lizards running bipedally, suggesting that bipedality was possible early in lizard evolution. PMID- 29449578 TI - Probing Conformal Invariant of Non-unitary Two-Dimensional Systems by Central Spin Decoherence. AB - Universality classes of non-unitary critical theories in two-dimensions are characterized by the central charge. However, experimental determination of the central charge of a non-unitary critical theory has not been done before because of the intrinsic difficulty that complex parameters usually occur in non-unitary theory, which is not physical. Here we propose to extract the effective central charge of the non-unitary critical point of a two-dimensional lattice model from the quantum coherence measurement of a probe spin which is coupled to the lattice model. A recent discovery shows that quantum coherence of a probe spin which is coupled to a bath is proportional to the partition function of the bath with a complex parameter. Thus the effective central charge of a non-unitary conformal field theory may be extracted from quantum coherence measurement of a probe spin which is coupled to a bath. We have applied the method to the Yang-Lee edge singularity of the two-dimensional Ising model and extracted the effective central charge of the Yang-Lee edge singularity with good precision and tested other predictions of non-unitary conformal field theory. This work paves the way for the first experimental observation of the effective central charge of non unitary conformal field theory. PMID- 29449577 TI - Neutralization of IL-15 abrogates experimental immune-mediated cholangitis in diet-induced obese mice. AB - Obesity is a global epidemic affecting chronic inflammatory diseases. Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease that can occur as an extraintestinal manifestation of inflammatory bowel disease (IBD). Previously we reported that patients with PSC who are obese have a higher risk of advanced liver disease. Currently it is unknown how obesity accelerates or worsens PSC. We evaluated the progression of PSC in an antigen-driven cholangitis mouse model of diet-induced obesity. Obesity was induced in our murine model of immune-mediated cholangitis (OVAbil). OVAbil mice were fed standard chow or high fat/sucrose diet for twelve weeks followed by induction of biliary inflammation by OVA-specific T cell transfer. Histopathological damage in portal tracts was scored and serum collected. Neutralizing antibodies against IL-15 were administered daily until study termination. Obese mice developed exacerbated liver inflammation and damage. Immune cell phenotyping in liver revealed greater numbers of neutrophils and CD8+ T cells in obese mice. Higher levels of cytokines and chemokines were found in obese mice with cholangitis. Immuno-neutralizing antibodies against IL-15 greatly attenuated cholangitis in obese mice. Obesity exacerbated experimental PSC in part by overproduction of IL-15. Timely targeting of IL-15 may slow the progression of PSC. PMID- 29449575 TI - Actionable perturbations of damage responses by TCL1/ATM and epigenetic lesions form the basis of T-PLL. AB - T-cell prolymphocytic leukemia (T-PLL) is a rare and poor-prognostic mature T cell malignancy. Here we integrated large-scale profiling data of alterations in gene expression, allelic copy number (CN), and nucleotide sequences in 111 well characterized patients. Besides prominent signatures of T-cell activation and prevalent clonal variants, we also identify novel hot-spots for CN variability, fusion molecules, alternative transcripts, and progression-associated dynamics. The overall lesional spectrum of T-PLL is mainly annotated to axes of DNA damage responses, T-cell receptor/cytokine signaling, and histone modulation. We formulate a multi-dimensional model of T-PLL pathogenesis centered around a unique combination of TCL1 overexpression with damaging ATM aberrations as initiating core lesions. The effects imposed by TCL1 cooperate with compromised ATM toward a leukemogenic phenotype of impaired DNA damage processing. Dysfunctional ATM appears inefficient in alleviating elevated redox burdens and telomere attrition and in evoking a p53-dependent apoptotic response to genotoxic insults. As non-genotoxic strategies, synergistic combinations of p53 reactivators and deacetylase inhibitors reinstate such cell death execution. PMID- 29449579 TI - Analysis of Epistasis among QTLs on Heading Date based on Single Segment Substitution Lines in Rice. AB - Heading date directly determines the planting districts and seasons, and thus plays an important role for producing and introducing of varieties. Limited to the materials and methodologies, analysis of epistasis still presents an obvious challenge. This thesis estimated effectively four types of epistatic components among dual QTLs on heading date based on eight single segment substitution lines (SSSLs) in rice. The results confirmed that they carried truly with heading date QTLs. Eleven pairs of QTLs were with 50.0% of significant epistatic effects, of which additive-additive, additive-dominance or dominance-additive, and dominance dominance interaction components occupied 40.9%, 50.0% and 59.1%, respectively. One QTL always interacted with multiple QTLs in various components. Several characteristics of epistasis on heading date were found that 1) different epistatic components had almost consistent directions; 2) dominance-dominance epistasis was perhaps most important in the four epistatic components; 3) epistasis was mostly positive, delaying rice heading; and 4) all epistatic components were seasonal sensitive. Two flowering pathways were further confirmed via a network constructed among these QTLs. These results have further confirmed the prevalence of epistatic interactions, deepened the understanding of genetic and flowering mechanism, and excavated several advantageous genes on heading date in rice. PMID- 29449580 TI - Botulinum neurotoxin-encoding plasmids can be conjugatively transferred to diverse clostridial strains. AB - Most Group I Clostridium botulinum strains harbor botulinum neurotoxin (bont) genes on their chromosome, while some carry these genes (including bont/a, bont/b, and bont/f) on large plasmids. Prior work in our laboratory demonstrated that Group I BoNT plasmids were mobilized to C. botulinum recipient strains containing the Tn916 transposon. Here, we show that Tn916 is nonessential for plasmid transfer. Relying on an auxotrophic donor phenotype and a plasmid-borne selectable marker, we observed the transfer of pCLJ, a 270 kb plasmid harboring two bont genes, from its host strain to various clostridia. Transfer frequency was greatest to other Group I C. botulinum strains, but the plasmid was also transferred into traditionally nontoxigenic species, namely C. sporogenes and C. butyricum. Expression and toxicity of BoNT/A4 was confirmed in transconjugants by immunoblot and mouse bioassay. These data indicate that conjugation within the genus Clostridium can occur across physiological Groups of C. botulinum, supporting horizontal gene transfer via bont-bearing plasmids. The transfer of plasmids possessing bont genes to resistant Clostridium spp. such as C. sporogenes could impact biological safety for animals and humans. These plasmids may play an environmental role in initiating death in vertebrates, leading to decomposition and nutrient recycling of animal biomass. PMID- 29449581 TI - Dyslipidemia and risk of renal replacement therapy or death in incident pre dialysis patients. AB - Globally the number of patients on renal replacement therapy (RRT) is rising. Dyslipidemia is a potential modifiable cardiovascular risk factor, but its effect on risk of RRT or death in pre-dialysis patients is unclear. The aim of this study was to assess the association between dyslipidemia and risk of RRT or death among patients with CKD stage 4-5 receiving specialized pre-dialysis care, an often under represented group in clinical trials. Of the 502 incident pre dialysis patients (>18 y) in the Dutch PREPARE-2 study, lipid levels were available in 284 patients and imputed for the other patients. During follow up 376 (75%) patients started RRT and 47 (9%) patients died. Dyslipidemia was defined as total cholesterol >=5.00 mmol/L, LDL cholesterol >=2.50 mmol/L, HDL cholesterol <1.00 mmol/L, HDL/LDL ratio <0.4, or triglycerides (TG) >=2.25 mmol/L, and was present in 181 patients and absent in 93 patients. After multivariable adjustment Cox regression analyses showed a HR (95% CI) for the combined endpoint for dyslipidemia of 1.12 (0.85-1.47), and for high LDL of 1.20 (0.89-1.61). All other HRs were smaller. In conclusion, we did not find an association between dyslipidemia or the separate lipid levels and RRT or death in CKD patients on specialized pre-dialysis care. PMID- 29449582 TI - Use of ELISpot assay to study HBs-specific B cell responses in vaccinated and HBV infected humans. AB - Hepatitis B surface antibody (HBsAb) plays a critical role in protecting against infection of hepatitis B virus (HBV) and were extensively studied in literature. At the same time, the status of hepatitis B surface antigen (HBs)-specific B cells in both vaccinated and HBV infected people received limited attention. In the current study, we adopted a highly specific B-cell Enzyme Linked ImmunoSpot (ELISpot) assay to analyze HBs-specific B cells in various clinical settings: healthy individuals with the history of HBV vaccination before and after receiving an extra HBV vaccine boost, people chronically infected with HBV (CHB) in various clinical stages, with or without a particular type anti-viral treatment, or whether receiving a dose of HBV vaccine. In all of these cases, B cell ELISpot assay was used effectively in enumerating the frequency of HBs specific B cells. While the focus of the current report was to establish the utility of this assay for HBV research, a number of interesting observations were made in this pilot study based on the profiles and dynamics of HBs-specific B cells in various conditions. Such information is useful to guide the future work in designing novel therapeutic strategies against CHB. PMID- 29449583 TI - Mesoporous silica nanocarriers encapsulated antimalarials with high therapeutic performance. AB - The use of nanocarriers in drug delivery is a breakeven research and has received a clarion call in biomedicine globally. Herein, two newly nano-biomaterials: MCM 41 encapsulated quinine (MCM-41 ? QN) (1) and 3-phenylpropyl silane functionalized MCM-41 loaded QN (pMCM-41 ? QN) (2) were synthesized and well characterized. 1 and 2 along with our two already reported nano-antimalarial drugs (MCM-41 ? ATS) (3) and 3-aminopropyl silane functionalized MCM-41 contained ATS (aMCM-41 ? ATS) (4) were screened in vitro for their activity against P. falciparium W2 strain, cytotoxicity against BGM cells and in vivo for their activity against Plasmodium bergheiNK65. 1 has the highest antimalarial activity in vivo against P. berghei NK65, (ED50: < 0.0625 mg/kg body weight) and higher mean survival time compared to the other nano biomaterials or unencapsulated drugs at doses higher than 0.0625 mg/kg body weight. This encapsulation strategy of MCM-41 ? QN (1) stands very useful and effective in delivering the drug to the target cells compared to other delivery systems and therefore, this encapsulated drug may be considered for rational drug design. PMID- 29449584 TI - CRISPR whole-genome screening identifies new necroptosis regulators and RIPK1 alternative splicing. AB - The necroptotic cell death pathway is a key component of human pathogen defense that can become aberrantly derepressed during tissue homeostasis to contribute to multiple types of tissue damage and disease. While formation of the necrosome kinase signaling complex containing RIPK1, RIPK3, and MLKL has been extensively characterized, additional mechanisms of its regulation and effector functions likely remain to be discovered. We screened 19,883 mouse protein-coding genes by CRISPR/Cas9-mediated gene knockout for resistance to cytokine-induced necroptosis and identified 112 regulators and mediators of necroptosis, including 59 new candidate pathway components with minimal or no effect on cell growth in the absence of necroptosis induction. Among these, we further characterized the function of PTBP1, an RNA binding protein whose activity is required to maintain RIPK1 protein abundance by regulating alternative splice-site selection. PMID- 29449585 TI - Electrical coupling between A17 cells enhances reciprocal inhibitory feedback to rod bipolar cells. AB - A17 amacrine cells are an important part of the scotopic pathway. Their synaptic varicosities receive glutamatergic inputs from rod bipolar cells (RBC) and release GABA onto the same RBC terminal, forming a reciprocal feedback that shapes RBC depolarization. Here, using patch-clamp recordings, we characterized electrical coupling between A17 cells of the rat retina and report the presence of strongly interconnected and non-coupled A17 cells. In coupled A17 cells, evoked currents preferentially flow out of the cell through GJs and cross synchronization of presynaptic signals in a pair of A17 cells is correlated to their coupling degree. Moreover, we demonstrate that stimulation of one A17 cell can induce electrical and calcium transients in neighboring A17 cells, thus confirming a functional flow of information through electrical synapses in the A17 coupled network. Finally, blocking GJs caused a strong decrease in the amplitude of the inhibitory feedback onto RBCs. We therefore propose that electrical coupling between A17 cells enhances feedback onto RBCs by synchronizing and facilitating GABA release from inhibitory varicosities surrounding each RBC axon terminal. GJs between A17 cells are therefore critical in shaping the visual flow through the scotopic pathway. PMID- 29449586 TI - Seismic waveform simulation for models with fluctuating interfaces. AB - The contrast of elastic properties across a subsurface interface imposes a dominant influence on the seismic wavefield, which includes transmitted and reflected waves from the interface. Therefore, for an accurate waveform simulation, it is necessary to have an accurate representation of the subsurface interfaces within the numerical model. Accordingly, body-fitted gridding is used to partition subsurface models so that the grids coincide well with both the irregular surface and fluctuating interfaces of the Earth. However, non rectangular meshes inevitably exist across fluctuating interfaces. This non orthogonality degrades the accuracy of the waveform simulation when using a conventional finite-difference method. Here, we find that a summation-by-parts (SBP) finite-difference method can be used for models with non-rectangular meshes across fluctuating interfaces, and can achieve desirable simulation accuracy. The acute angle of non-rectangular meshes can be relaxed to as low as 47 degrees . The cell size rate of change between neighbouring grids can be relaxed to as much as 30%. Because the non-orthogonality of grids has a much smaller impact on the waveform simulation accuracy, the model discretisation can be relatively flexible for fitting fluctuating boundaries within any complex problem. Consequently, seismic waveform inversion can explicitly include fluctuating interfaces within a subsurface velocity model. PMID- 29449588 TI - Spectral features of the tunneling-induced transparency and the Autler-Townes doublet and triplet in a triple quantum dot. AB - We theoretically investigate the spectral features of tunneling-induced transparency (TIT) and Autler-Townes (AT) doublet and triplet in a triple-quantum dot system. By analyzing the eigenenergy spectrum of the system Hamiltonian, we can discriminate TIT and double TIT from AT doublet and triplet, respectively. For the resonant case, the presence of the TIT does not exhibit distinguishable anticrossing in the eigenenergy spectrum in the weak-tunneling regime, while the occurrence of double anticrossings in the strong-tunneling regime shows that the TIT evolves to the AT doublet. For the off-resonance case, the appearance of a new detuning-dependent dip in the absorption spectrum leads to double TIT behavior in the weak-tunneling regime due to no distinguished anticrossing occurring in the eigenenergy spectrum. However, in the strong-tunneling regime, a new detuning-dependent dip in the absorption spectrum results in AT triplet owing to the presence of triple anticrossings in the eigenenergy spectrum. Our results can be applied to quantum measurement and quantum-optics devices in solid systems. PMID- 29449587 TI - The Mechanisms of Bushen-Yizhi Formula as a Therapeutic Agent against Alzheimer's Disease. AB - Bushen-Yizhi prescription (BSYZ) has been an effective traditional Chinese medicine (TCM) prescription in treating Alzheimer's disease (AD) for hundreds of years. However, the underlying mechanisms have not been fully elucidated yet. In this work, a systems pharmacology approach was developed to reveal the underlying molecular mechanisms of BSYZ in treating AD. First, we obtained 329 candidate compounds of BSYZ by in silico ADME/T filter analysis and 138 AD-related targets were predicted by our in-house WEGA algorithm via mapping predicted targets into AD-related proteins. In addition, we elucidated the mechanisms of BSYZ action on AD through multiple network analysis, including compound-target network analysis and target-function network analysis. Furthermore, several modules regulated by BSYZ were incorporated into AD-related pathways to uncover the therapeutic mechanisms of this prescription in AD treatment. Finally, further verification experiments also demonstrated the therapeutic effects of BSYZ on cognitive dysfunction in APP/PS1 mice, which was possibly via regulating amyloid-beta metabolism and suppressing neuronal apoptosis. In conclusion, we provide an integrative systems pharmacology approach to illustrate the underlying therapeutic mechanisms of BSYZ formula action on AD. PMID- 29449589 TI - Loss of the homeostatic protein BPIFA1, leads to exacerbation of otitis media severity in the Junbo mouse model. AB - Otitis Media (OM) is characterized by epithelial abnormalities and defects in innate immunity in the middle ear (ME). Although, BPIFA1, a member of the BPI fold containing family of putative innate defence proteins is abundantly expressed by the ME epithelium and SNPs in Bpifa1 have been associated with OM susceptibility, its role in the ME is not well characterized. We investigated the role of BPIFA1 in protection of the ME and the development of OM using murine models. Loss of Bpifa1 did not lead to OM development. However, deletion of Bpifa1 in Evi1Jbo/+ mice, a model of chronic OM, caused significant exacerbation of OM severity, thickening of the ME mucosa and increased collagen deposition, without a significant increase in pro-inflammatory gene expression. Our data suggests that BPIFA1 is involved in maintaining homeostasis within the ME under steady state conditions and its loss in the presence of inflammation, exacerbates epithelial remodelling leading to more severe OM. PMID- 29449590 TI - Lateral Force Microscopy of Interfacial Nanobubbles: Friction Reduction and Novel Frictional Behavior. AB - Atomic force microscopy is used to conduct single-asperity friction measurements at a water-graphite interface. Local mapping of the frictional force, which is based on the degree of the cantilever twisting, shows nearly friction-free when a tip scans over a nanobubble. Surprisingly, apart from being gapless, the associated friction loop exhibits a tilt in the cantilever twisting versus the tip's lateral displacement with the slope depending on the loading force. The sign of the slope reverses at around zero loading force. In addition, the measured normal and lateral tip-sample interactions exhibit unison versus tip sample separation. Theoretical analysis, based on the balance of forces on the tip originated from the capillary force of the nanobubble and the torsion of the cantilever, offers quantitative explanations for both the tilted friction loop and the unison of force curves. The analysis may well apply in a wider context to the lateral force characterization on cap-shaped fluid structures such as liquid droplets on a solid substrate. This study further points to a new direction for friction reduction between solids in a liquid medium. PMID- 29449591 TI - Familial Risks Between Urolithiasis and Cancer. AB - Urolithiasis (UL, urinary tract stone disease) has been reported to increase subsequent cancers in the urinary tract. Recently, we showed data that surveillance bias may be an important confounder in the reported associations. In the present approach we want to address the question of possible cancer risk posed by UL mechanistically. Both UL and cancer have strong genetic components and we hypothesize that familial association between UL and cancer may be plausible. We thus assess familial risks between UL and cancer, hoping to find an explanation why UL may pose a risk of cancer. UL patients were identified from hospital inpatient and outpatient records and they were organized in families based on the Multigeneration Register into which also national cancer data were linked. Standardized incidence ratios were calculated for cancer in the offspring generation when parents were diagnosed with UL, and conversely for UL when parents were diagnosed with cancer. Familial risks between UL and cancer were generally small and inconsistent providing no convincing support of genetic sharing between UL and cancer. However, bladder UL was associated weakly with prostate cancer, and ureter and bladder UL were associated with salivary gland cancer. Potential mechanisms for these findings are proposed. PMID- 29449592 TI - First evidence for a multienzyme complex of lipid biosynthesis pathway enzymes in Cunninghamella bainieri. AB - Malic enzyme (ME) plays a vital role in determining the extent of lipid accumulation in oleaginous fungi being the major provider of NADPH for the activity of fatty acid synthase (FAS). We report here the first direct evidence of the existence of a lipogenic multienzyme complex (the lipid metabolon) involving ME, FAS, ATP: citrate lyase (ACL), acetyl-CoA carboxylase (ACC), pyruvate carboxylase (PC) and malate dehydrogenase (MDH) in Cunninghamella bainieri 2A1. Cell-free extracts prepared from cells taken in both growth and lipid accumulation phases were prepared by protoplasting and subjected to Blue Native (BN)-PAGE coupled with liquid chromatography-tandem mass spectrometry (LC MS/MS). A high molecular mass complex (approx. 3.2 MDa) consisting of the above enzymes was detected during lipid accumulation phase indicating positive evidence of multienzyme complex formation. The complex was not detected in cells during the balanced phase of growth or when lipid accumulation ceased, suggesting that it was transiently formed only during lipogenesis. PMID- 29449593 TI - Hemopexin is required for adult neurogenesis in the subventricular zone/olfactory bulb pathway. AB - The neural stem cells (NSCs) of the subventricular zone (SVZ) reside within a specialized niche critical for neurogenesis. Hemopexin, a plasma glycoprotein, has been extensively studied as a heme scavenger at the systemic level. However, little is known about its function in the central nervous system, especially in neurogenesis. In the present study, we demonstrate that deletion of hemopexin leads to neurogenic abnormalities in the SVZ/olfactory bulb (OB) pathway. The lateral ventricle is enlarged in hemopexin-deficient mice, and more apoptosis was observed in Dcx+ cells. Lineage differentiation of NSCs was also inhibited in the SVZ of hemopexin-deficient mice, with more stem cells stayed in an undifferentiated, GFAP+ radial glia-like cell stage. Moreover, hemopexin deletion resulted in impaired neuroblast migration in the rostral migratory stream. Furthermore, exogenous hemopexin protein inhibited apoptosis and promoted the migration and differentiation of cultured NSCs. Finally, immunohistochemical analysis demonstrated that deletion of hemopexin reduced the number of interneurons in the OB. Together, these results suggest a new molecular mechanism for the NSC niche that regulates adult neurogenesis in the SVZ/OB pathway. Our findings may benefit the understanding for olfactory system development.

AB - Stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is one of the most devastating diseases of wheat. Resistant cultivars are the preferred strategy to control the disease. Space-induced wheat mutant R39 has adult-plant resistance (APR) to Pst. Genetic analysis indicated that a single recessive gene, designated YrR39, was responsible for the APR of R39 to Pst. Bulked segregant analysis (BSA) combined with a SLAF sequencing (SLAF-seq) strategy was used to fine-map YrR39 to a 17.39 Mb segment on chromosome 4B. The region was confirmed by analysis with simple sequence repeat (SSR) markers. A total of 126 genes were annotated in the region and 21 genes with annotations associated with disease response were selected for further qRT-PCR analysis. The candidate gene Traes_4BS_C868349E1 (annotated as an F-box/LRR-repeat protein) was up-regulated after 12, 24, 48, and 96 hours post inoculation with Pst, suggesting it is likely involved in the resistance. The current study demonstrated that BSA combined with SLAF-seq for SNP discovery is an efficient approach for mapping and identifying candidate functional gene. PMID- 29449595 TI - Temporal Differentiation of Crop Growth as One of the Drivers of Intercropping Yield Advantage. AB - Intercropping studies usually focus on yield advantage and interspecific interactions but few quantify temporal niche differentiation and its relationship with intercropping yield advantage. A field experiment conducted in northwest China in 2013 and 2014 examined four intercropping systems (oilseed rape/maize, oilseed rape/soybean, potato/maize, and soybean/potato) and the corresponding monocultures. Total dry matter data collected every 20 d after maize emergence were fitted to logistic models to investigate the temporal dynamics of crop growth and interspecific interactions. All four intercropping systems showed significant yield advantages. Temporal niche complementarity between intercropped species was due to differences in sowing and harvesting dates or the time taken to reach maximum daily growth rate or both. Interspecific interactions between intercropped species amplified temporal niche differentiation as indicated by postponement of the time taken to reach maximum daily growth rate of late maturing crops (i.e. 21 to 41 days in maize associated with oilseed rape or potato). Growth trajectories of intercropped maize or soybean recovered after the oilseed rape harvest to the same values as in their monoculture on a per plant basis. Amplified niche differentiation between crop species depends on the identity of neighboring species whose relative growth rate is crucial in determining the differentiation. PMID- 29449596 TI - Heparan sulfates facilitate harmless amyloidogenic fibril formation interacting with elastin-like peptides. AB - Heparan sulfates (HSs) modulate tissue elasticity in physiopathological conditions by interacting with various matrix constituents as tropoelastin and elastin-derived peptides. HSs bind also to protein moieties accelerating amyloid formation and influencing cytotoxic properties of insoluble fibrils. Interestingly, amyloidogenic polypeptides, despite their supposed pathogenic role, have been recently explored as promising bio-nanomaterials due to their unique and interesting properties. Therefore, we investigated the interactions of HSs, obtained from different sources and exhibiting various degree of sulfation, with synthetic amyloidogenic elastin-like peptides (ELPs), also looking at the effects of these interactions on cell viability and cell behavior using in vitro cultured fibroblasts, as a prototype of mesenchymal cells known to modulate the soft connective tissue environment. Results demonstrate, for the first time, that HSs, with differences depending on their sulfation pattern and chain length, interact with ELPs accelerating aggregation kinetics and amyloid-like fibril formation as well as self-association. Furthermore, these fibrils do not negatively affect fibroblasts' cell growth and parameters of redox balance, and influence cellular adhesion properties. Data provide information for a better understanding of the interactions altering the elastic component in aging and in pathologic conditions and may pave the way for the development of composite matrix-based biomaterials. PMID- 29449597 TI - Substructure-activity relationship studies on antibody recognition for phenylurea compounds using competitive immunoassay and computational chemistry. AB - Based on the structural features of fluometuron, an immunizing hapten was synthesized and conjugated to bovine serum albumin as an immunogen to prepare a polyclonal antibody. However, the resultant antibody indicated cross-reactivity with 6 structurally similar phenylurea herbicides, with binding activities (expressed by IC50 values) ranging from 1.67 ug/L to 42.71 ug/L. All 6 phenylurea herbicides contain a common moiety and three different substitutes. To understand how these three different chemical groups affect the antibody-phenylurea recognition activity, quantum chemistry, using density function theory (DFT) at the B3LYP/6-311++ G(d,p) level of theory, was employed to optimize all phenylurea structures, followed by determination of the 3D conformations of these molecules, pharmacophore analysis, and molecular electrostatic potential (ESP) analysis. The molecular modeling results confirmed that the geometry configuration, pharmacophore features and electron distribution in the substituents were related to the antibody binding activity. Spearman correlation analysis further elucidated that the geometrical and electrostatic properties on the van der Waals (vdW) surface of the substituents played a critical role in the antibody phenylurea recognition process. PMID- 29449598 TI - Health-related quality of life in adolescents and the retinal microvascular structure. AB - We aimed to investigate whether health-related quality of life (HRQoL) is associated with retinal vascular caliber, an indicator of subclinical cardiovascular disease risk. 1600 students aged between 11-19 years (821 girls and 779 boys) were examined during 2009-2011. Retinal vessel caliber was measured from digital retinal images. HRQoL was assessed by the Pediatric Quality of Life Inventory (PedsQL). In the overall cohort, each 1-unit increase in PedsQL total score and the psychosocial summary score was associated with ~0.05 MUm narrowing in retinal arteriolar caliber (multivariable-adjusted p-value = 0.01). Participants in the lowest versus highest tertile of PedsQL total score, psychosocial summary, social and school item scores had significantly wider retinal arteriolar caliber: 161.7 MUm versus 160.2 MUm (p = 0.02); 161.6 MUm versus 160.0 MUm (p = 0.02); 161.6 MUm versus 159.9 MUm (p = 0.002); and 161.6 MUm versus 159.9 MUm (p = 0.01), respectively. Significant interactions (p < 0.05) were observed between gender and PedsQL total score with retinal arteriolar calibre. In boys, inverse associations were observed between PedsQL total score (p = 0.01), psychosocial summary (p = 0.01), and social scores (p = 0.01) and retinal arteriolar caliber. No significant associations were observed between PedsQL scores and retinal vessel caliber in girls. Diminished HRQoL in adolescents was independently associated with structural retinal microvascular changes. PMID- 29449599 TI - Red blood cells are dynamic reservoirs of cytokines. AB - Red blood cells (RBCs) have been shown to affect immune function and can induce inflammatory responses after transfusion. The transfusion of washed RBCs can significantly reduce adverse effects, however, the soluble factors that may mediate these effects have not been identified. Previous studies have identified, but not quantified, a small number of chemokines associated with RBCs. We isolated RBCs from healthy volunteers and quantified of a panel of 48 cytokines, chemokines, and growth factors in the lysate, cytosol, and conditioned media of these cells using Luminex(r) technology. This analysis revealed that, after correcting for white blood cell and platelet contamination, 46 cytokines were detected in RBC lysates, and the median concentration in RBCs was 12-fold higher than in the plasma. In addition, extensive washing of RBCs, such as that performed in proteomics analyses or prior to some RBC transfusions, significantly attenuated the release of six cytokines following incubation at 37 degrees C. This supports the hypothesis that, alongside its gas exchange function, RBCs play a role in cytokine signalling. This discovery may help supplement disease biomarker research and may shed light on adverse inflammatory processes that can follow RBC transfusion. PMID- 29449601 TI - Solar Thermo-coupled Electrochemical Oxidation of Aniline in Wastewater for the Complete Mineralization Beyond an Anodic Passivation Film. AB - Herein, we report the solar thermal electrochemical process (STEP) aniline oxidation in wastewater for totally solving the two key obstacles of the huge energy consumption and passivation film in the electrochemical treatment. The process, fully driven by solar energy without input of any other energies, sustainably serves as an efficient thermoelectrochemical oxidation of aniline by the control of the thermochemical and electrochemical coordination. The thermocoupled electrochemical oxidation of aniline achieved a fast rate and high efficiency for the full minimization of aniline to CO2 with the stability of the electrode and without formation of polyaniline (PAN) passivation film. A clear mechanism of aniline oxidation indicated a switching of the reactive pathway by the STEP process. Due to the coupling of solar thermochemistry and electrochemistry, the electrochemical current remained stable, significantly improving the oxidation efficiency and mineralization rate by apparently decreasing the electrolytic potential when applied with high temperature. The oxidation rate of aniline and chemical oxygen demand (COD) removal rate could be lifted up to 2.03 and 2.47 times magnification compared to conventional electrolysis, respectively. We demonstrate that solar-driven STEP processes are capable of completely mineralizing aniline with high utilization of solar energy. STEP aniline oxidation can be utilized as a green, sustainable water treatment. PMID- 29449600 TI - Glucocorticoids promote apoptosis of proinflammatory monocytes by inhibiting ERK activity. AB - Glucocorticoids (GCs) are potent anti-inflammatory drugs whose mode of action is complex and still debatable. One likely cellular target of GCs are monocytes/macrophages. The role of GCs in monocyte survival is also debated. Although both granulocyte macrophage-colony stimulating factor (GM-CSF) and macrophage-CSF (M-CSF) are important regulators of macrophage lineage functions including their survival, the former is often associated with proinflammatory functions while the latter is important in lineage homeostasis. We report here that the GC, dexamethasone, induces apoptosis in GM-CSF-treated human monocytes while having no impact on M-CSF-induced monocyte survival. To understand how GCs, GM-CSF, and M-CSF are regulating monocyte survival and other functions during inflammation, we firstly examined the transcriptomic changes elicited by these three agents in human monocytes, either acting alone or in combination. Transcriptomic and Ingenuity pathway analyses found that dexamethasone differentially modulated dendritic cell maturation and TREM1 signaling pathways in GM-CSF-treated and M-CSF-treated monocytes, two pathways known to be regulated by ERK1/2 activity. These analyses led us to provide evidence that the GC inhibits ERK1/2 activity selectively in GM-CSF-treated monocytes to induce apoptosis. It is proposed that this inhibition of ERK1/2 activity leads to inactivation of p90 ribosomal-S6 kinase and Bad dephosphorylation leading in turn to enhanced caspase-3 activity and subsequent apoptosis. Furthermore, pharmacological inhibition of GC receptor activity restored the ERK1/2 signaling and prevented the GC-induced apoptosis in GM-CSF-treated monocytes. Increased tissue macrophage numbers, possibly from enhanced survival due to mediators such as GM-CSF, can correlate with inflammatory disease severity; also reduction in these numbers can correlate with the therapeutic benefit of a number of agents, including GCs. We propose that the ERK1/2 signaling pathway promotes survival of GM-CSF-treated proinflammatory monocytes, which can be selectively targeted by GCs as a novel mechanism to reduce local monocyte/macrophage numbers and hence inflammation. PMID- 29449602 TI - Diamond FinFET without Hydrogen Termination. AB - In this letter we report the first diamond fin field-effect transistor (diamond FinFET) without a hydrogen-terminated channel. The device operates with hole accumulation by metal-oxide-semiconductor (MOS) structures built on fins to maintain effective control of the channel conduction. Devices with 100-nm-wide fins were designed and fabricated to ensure that the channel pinched off at zero gate bias. The transfer characteristic of FinFET showed a greater than 3000 on/off ratio, successfully demonstrating the transistor behavior. Devices were characterized at room temperature and at 150 degrees C, showing 30 mA/mm current density at 150 degrees C, 35 times more than current density at room temperature. The diamond FinFET, which leverages the fin concept from the silicon industry and the material advance of diamond, enables a new class of diamond transistors for applications from digital to power and radio frequency (RF) electronics. PMID- 29449603 TI - Cinacalcet versus Placebo for secondary hyperparathyroidism in chronic kidney disease patients: a meta-analysis of randomized controlled trials and trial sequential analysis. AB - To assess the efficacy and safety of cinacalcet on secondary hyperparathyroidism in patients with chronic kidney disease, Pubmed, Embase, and the Cochrane Central Register of Controlled Trials were searched until March 2016. Trial sequential analysis (TSA) was conducted to control the risks of type I and II errors and calculate required information size (RIS). A total of 25 articles with 8481 participants were included. Compared with controls, cinacalcet administration did not reduce all-cause mortality (RR = 0.97, 95% CI = 0.89-1.05, P = 0.41, TSA adjusted 95% CI = 0.86-1.08, RIS = 5260, n = 8386) or cardiovascular mortality (RR = 0.95, 95% CI = 0.83-1.07, P = 0.39, TSA-adjusted 95% CI = 0.70-1.26, RIS = 3780 n = 5418), but it reduced the incidence of parathyroidectomy (RR = 0.48, 95% CI = 0.40-0.50, P < 0.001, TSA-adjusted 95% CI = 0.39-0.60, RIS = 5787 n = 5488). Cinacalcet increased the risk of hypocalcemia (RR = 8.48, 95% CI = 6.37-11.29, P < 0.001, TSA-adjusted 95% CI = 5.25-13.70, RIS = 6522, n = 7785), nausea (RR = 2.12, 95% CI = 1.62-2.77, P < 0.001, TSA-adjusted 95% CI = 1.45-3.04, RIS = 4684, n = 7512), vomiting (RR = 2.00, 95% CI = 1.79-2.24, P < 0.001, TSA-adjusted 95% CI = 1.77-2.26, RIS = 1374, n = 7331) and diarrhea (RR = 1.17, 95% CI = 1.05 1.32, P = 0.006, TSA-adjusted 95% CI = 1.02-1.36, RIS = 8388, n = 6116). Cinacalcet did not significantly reduce the incidence of fractures (RR = 0.58, 95% CI = 0.21-1.59, P = 0.29, TSA-adjusted 95% CI = 0.01-35.11, RIS = 76376, n = 4053). Cinacalcet reduced the incidence of parathyroidectomy, however, it did not reduce all-cause and cardiovascular mortality, and increased the risk of adverse events including hypocalcemia and gastrointestinal disorders. PMID- 29449604 TI - Intravenous synthetic platelet (SynthoPlate) nanoconstructs reduce bleeding and improve 'golden hour' survival in a porcine model of traumatic arterial hemorrhage. AB - Traumatic non-compressible hemorrhage is a leading cause of civilian and military mortality and its treatment requires massive transfusion of blood components, especially platelets. However, in austere civilian and battlefield locations, access to platelets is highly challenging due to limited supply and portability, high risk of bacterial contamination and short shelf-life. To resolve this, we have developed an I.V.-administrable 'synthetic platelet' nanoconstruct (SynthoPlate), that can mimic and amplify body's natural hemostatic mechanisms specifically at the bleeding site while maintaining systemic safety. Previously we have reported the detailed biochemical and hemostatic characterization of SynthoPlate in a non-trauma tail-bleeding model in mice. Building on this, here we sought to evaluate the hemostatic ability of SynthoPlate in emergency administration within the 'golden hour' following traumatic hemorrhagic injury in the femoral artery, in a pig model. We first characterized the storage stability and post-sterilization biofunctionality of SynthoPlate in vitro. The nanoconstructs were then I.V.-administered to pigs and their systemic safety and biodistribution were characterized. Subsequently we demonstrated that, following femoral artery injury, bolus administration of SynthoPlate could reduce blood loss, stabilize blood pressure and significantly improve survival. Our results indicate substantial promise of SynthoPlate as a viable platelet surrogate for emergency management of traumatic bleeding. PMID- 29449605 TI - Image Transport Through Meter-Long Randomly Disordered Silica-Air Optical Fiber. AB - We present a randomly disordered silica-air optical fiber featuring a 28.5% air filling fraction in the structured region, and low attenuation below 1 dB per meter at visible wavelengths. The quality of images transported through this fiber is shown to be comparable to, or even better than, that of images sent through commercial multicore imaging fiber. We demonstrate robust high-quality optical image transfer through 90 cm-long fibers with disordered silica-air structure, more than an order of magnitude improvement compared to previous disordered fiber imaging distances. The effects of variations of wavelength and feature size on transported image quality are investigated experimentally. PMID- 29449606 TI - Human subarachnoid space width oscillations in the resting state. AB - Abnormal cerebrospinal fluid (CSF) pulsatility has been implicated in patients suffering from various diseases, including multiple sclerosis and hypertension. CSF pulsatility results in subarachnoid space (SAS) width changes, which can be measured with near-infrared transillumination backscattering sounding (NIR T/BSS). The aim of this study was to combine NIR-T/BSS and wavelet analysis methods to characterise the dynamics of the SAS width within a wide range of frequencies from 0.005 to 2 Hz, with low frequencies studied in detail for the first time. From recordings in the resting state, we also demonstrate the relationships between SAS width in both hemispheres of the brain, and investigate how the SAS width dynamics is related to the blood pressure (BP). These investigations also revealed influences of age and SAS correlation on the dynamics of SAS width and its similarity with the BP. Combination of NIR-T/BSS and time-frequency analysis may open up new frontiers in the understanding and diagnosis of various neurodegenerative and ageing related diseases to improve diagnostic procedures and patient prognosis. PMID- 29449607 TI - 6-Thioguanine is a noncompetitive and slow binding inhibitor of human deubiquitinating protease USP2. AB - Ubiquitin-specific protease 2 (USP2) belongs to the family of deubiquitinases that can rescue protein targets from proteasomal degradation by reversing their ubiquitination. In various cancers, including prostate cancer and ovarian carcinoma, upregulation of USP2 leads to an increase in the levels of deubiquitinated substrates such as fatty acid synthase, MDM2, cyclin D1 and Aurora-A. USP2 thus plays a critical role in tumor cells' survival and therefore represents a therapeutic target. Here a leukemia drug, 6-thioguanine, was found to be a potent inhibitor of USP2. Enzyme-kinetic and X-ray crystallographic data suggest that 6-thioguanine displays a noncompetitive and slow-binding inhibitory mechanism against USP2. Our study provides a clear rationale for the clinical evaluation of 6-thioguanine for USP2-upregulated cancers. PMID- 29449608 TI - Mapping molecular assemblies with fluorescence microscopy and object-based spatial statistics. AB - Elucidating protein functions and molecular organisation requires to localise precisely single or aggregated molecules and analyse their spatial distributions. We develop a statistical method SODA (Statistical Object Distance Analysis) that uses either micro- or nanoscopy to significantly improve on standard co localisation techniques. Our method considers cellular geometry and densities of molecules to provide statistical maps of isolated and associated (coupled) molecules. We use SODA with three-colour structured-illumination microscopy (SIM) images of hippocampal neurons, and statistically characterise spatial organisation of thousands of synapses. We show that presynaptic synapsin is arranged in asymmetric triangle with the 2 postsynaptic markers homer and PSD95, indicating a deeper localisation of homer. We then determine stoichiometry and distance between localisations of two synaptic vesicle proteins with 3D-STORM. These findings give insights into the protein organisation at the synapse, and prove the efficiency of SODA to quantitatively assess the geometry of molecular assemblies. PMID- 29449609 TI - Kinesthetic stimulation for obstructive sleep apnea syndrome: An "on-off" proof of concept trial. AB - Obstructive sleep apnea (OSA) occurs when the upper airway narrows or collapses due to the loss of upper airway muscle activation at sleep onset. This study investigated the effectiveness of triggered kinesthetic stimulation in patients with OSA. This proof-of-concept, open-label, multicenter prospective study was conducted on 24 patients with severe OSA. During a one night evaluation, kinesthetic stimulation was intermittently delivered in 30 minute periods. The duration of apneas and hypopneas during Stim on and Stim off periods were compared. Five hospital-based university centers in France participated. Sleep studies were evaluated by a single scorer at a core laboratory (CHU Grenoble). Results show that during the Stim on phases, statistically significant decreases in durations of apneas and hypopneas were observed in 56% and 46% of patients, respectively. Overall, 75% of patients showed an improvement in apneas or hypopneas durations. The mean reduction in durations for patients with a significant decrease was 4.86 seconds for apneas and 6.00 seconds for hypopneas. This proof of concept study is the first to identify kinesthetic stimulation as a potentially effective therapy for OSA. These data justify evaluation in a controlled study. PMID- 29449610 TI - Phaeophleospora vochysiae Savi & Glienke sp. nov. Isolated from Vochysia divergens Found in the Pantanal, Brazil, Produces Bioactive Secondary Metabolites. AB - Microorganisms associated with plants are highly diverse and can produce a large number of secondary metabolites, with antimicrobial, anti-parasitic and cytotoxic activities. We are particularly interested in exploring endophytes from medicinal plants found in the Pantanal, a unique and widely unexplored wetland in Brazil. In a bio-prospecting study, strains LGMF1213 and LGMF1215 were isolated as endophytes from Vochysia divergens, and by morphological and molecular phylogenetic analyses were characterized as Phaeophleospora vochysiae sp. nov. The chemical assessment of this species reveals three major compounds with high biological activity, cercoscosporin (1), isocercosporin (2) and the new compound 3-(sec-butyl)-6-ethyl-4,5-dihydroxy-2-methoxy-6-methylcyclohex-2-enone (3). Besides the isolation of P. vochysiae as endophyte, the production of cercosporin compounds suggest that under specific conditions this species causes leaf spots, and may turn into a pathogen, since leaf spots are commonly caused by species of Cercospora that produce related compounds. In addition, the new compound 3-(sec butyl)-6-ethyl-4,5-dihydroxy-2-methoxy-6-methylcyclohex-2-enone showed considerable antimicrobial activity and low cytotoxicity, which needs further exploration. PMID- 29449611 TI - Seasonal resource conditions favor a summertime increase in North Pacific diatom diazotroph associations. AB - In the North Pacific Subtropical Gyre (NPSG), an annual pulse of sinking organic carbon is observed at 4000 m between July and August, driven by large diatoms found in association with nitrogen fixing, heterocystous, cyanobacteria: Diatom Diazotroph Associations (DDAs). Here we ask what drives the bloom of DDAs and present a simplified trait-based model of subtropical phototroph populations driven by observed, monthly averaged, environmental characteristics. The ratio of resource supply rates favors nitrogen fixation year round. The relative fitness of DDA traits is most competitive in early summer when the mixed layer is shallow, solar irradiance is high, and phosphorus and iron are relatively abundant. Later in the season, as light intensity drops and phosphorus is depleted, the traits of small unicellular diazotrophs become more competitive. The competitive transition happens in August, at the time when the DDA export event occurs. This seasonal dynamic is maintained when embedded in a more complex, global-scale, ecological model, and provides predictions for the extent of the North Pacific DDA bloom. The model provides a parsimonious and testable hypothesis for the stimulation of DDA blooms. PMID- 29449613 TI - Health-care spending and utilization for children discharged from a neonatal intensive care unit. AB - OBJECTIVES: To describe health-care spending and utilization for infants discharged from the neonatal intensive care unit (NICU). STUDY DESIGN: Retrospective cohort analysis of 4973 NICU graduates in the Truven MarketScan Medicaid database, with follow-up to the third birthday. Health-care spending and utilization after NICU discharge were assessed. Using logistic regression, we assessed clinical characteristics associated with hospitalization and emergency department (ED) visits. RESULTS: Most (69.5%) post-NICU spending occurred within the first year [$33,276 per member per year]. Inpatient care accounted for most (71.6%) of the 3-year spending. The percentages of infants with a 1-year readmission or ED visit were 36.8% and 63.7%, respectively. Medical technology was associated with the highest likelihoods of hospital [aOR 17.8 (95%CI 12.2 26.0)] and ED use [aOR 2.3 (95%CI 1.8-3.0)]. CONCLUSIONS: Hospital care accounts for the majority of spending for NICU graduates. Infants with medical technology have the highest risk of hospital and ED use. PMID- 29449612 TI - Ixr1 Regulates Ribosomal Gene Transcription and Yeast Response to Cisplatin. AB - Ixr1 is a Saccharomyces cerevisiae HMGB protein that regulates the hypoxic regulon and also controls the expression of other genes involved in the oxidative stress response or re-adaptation of catabolic and anabolic fluxes when oxygen is limiting. Ixr1 also binds with high affinity to cisplatin-DNA adducts and modulates DNA repair. The influence of Ixr1 on transcription in the absence or presence of cisplatin has been analyzed in this work. Ixr1 regulates other transcriptional factors that respond to nutrient availability or extracellular and intracellular stress stimuli, some controlled by the TOR pathway and PKA signaling. Ixr1 controls transcription of ribosomal RNAs and genes encoding ribosomal proteins or involved in ribosome assembly. qPCR, ChIP, and 18S and 25S rRNAs measurement have confirmed this function. Ixr1 binds directly to several promoters of genes related to rRNA transcription and ribosome biogenesis. Cisplatin treatment mimics the effect of IXR1 deletion on rRNA and ribosomal gene transcription, and prevents Ixr1 binding to specific promoters related to these processes. PMID- 29449614 TI - Decreased succinate dehydrogenase B in human hepatocellular carcinoma accelerates tumor malignancy by inducing the Warburg effect. AB - Changes in TCA cycle enzymes or respiratory activity are possible mechanisms of aerobic glycolysis that contributes to tumor progression. To clarify whether the decrease of succinate dehydrogenase B (SDHB) alters energy metabolism, induces the Warburg effect and results in tumor malignancy, SDHB expression was examined and modulated in hepatocellular carcinoma (HCC) tissues and cells, respectively. SDHB level was often decreased in malignant HCC cells and tissues. Furthermore, the reduced SDHB expression was associated with advanced tumor stage and poor survival rate. Moreover, silencing of SDHB altered energy metabolism switched from aerobic respiration to glycolysis, resulted in the Warburg effect, and enhanced cell proliferation and motility. In contrast, the SDHB overexpression deregulated bioenergetic metabolism and decreased cell growth and migration. In mouse xenograft models, subcutaneous implantation and tail vein injection with SDHB knockdown cells resulted in a larger tumor volume and accelerated cancer metastasis, respectively. A mutation or decrease in SDHB induced the switch from aerobic respiration to glycolysis. This metabolic alteration was associated with tumor cell dedifferentiation, proliferation, motility and overall patient survival in HCC.

AB - OBJECTIVES: To examine the effect of subthreshold diode micropulse laser (SDM) on pattern electroretinography (PERG) and visual function in retinitis pigmentosa (RP). METHODS: The records of all patients (pts) undergoing SDM in a vitreoretinal subspecialty practice were reviewed. Inclusion criteria included the presence of RP evaluated before and after SDM by PERG. As a secondary outcome measure, the results of automated omnifield resolution perimetry (ORP) were also reviewed. RESULTS: All eyes undergoing SDM for RP were eligible study, including 26 eyes of 15 pts; seven male and eight female, aged 16-69 (avg. 47) years. Retinal function by PERG improved by all indices, with significant improvements in the 24 degrees field signal latency measures; the MagD(uV)/ Mag(uV) ratio (P < 0.0001) and the MagD(uV) amplitude (P = 0.0003). ORP significantly improved by all indices (p = 0.02-0.002). Average best-corrected chart visual acuities improved from 0.6 to 0.4 logMAR units (p = 0.02). There were no adverse treatment effects. CONCLUSIONS: SDM significantly improved chart visual acuity, mesopic logMAR visual acuity perimetry, and retinal function by PERG in RP without adverse treatment effects. Treatment responses indicate a significant capacity for rescue of dysfunctional retina. These results suggest that early and periodic treatment with SDM might slow disease progression and reduce long-term vision loss.

PMID- 29449618 TI - Codon based co-occurrence network motifs in human mitochondria. AB - The nucleotide polymorphism in the human mitochondrial genome (mtDNA) tolled by codon position bias plays an indispensable role in human population dispersion and expansion. Herein, genome-wide nucleotide co-occurrence networks were constructed using data comprised of five different geographical regions and around 3000 samples for each region. We developed a powerful network model to describe complex mitochondrial evolutionary patterns among codon and non-codon positions. We found evidence that the evolution of human mitochondria DNA is dominated by adaptive forces, particularly mutation and selection, which was supported by many previous studies. The diversity observed in the mtDNA was compared with mutations, co-occurring mutations, network motifs considering codon positions as causing agent. This comparison showed that long-range nucleotide co occurrences have a large effect on genomic diversity. Most notably, codon motifs apparently underpinned the preferences among codon positions for co-evolution which is probably highly biased during the origin of the genetic code. Our analysis also showed that variable nucleotide positions of different human sub populations implemented the independent mtDNA evolution to its geographical dispensation. Ergo, this study has provided both a network framework and a codon glance to investigate co-occurring genomic variations that are critical in underlying complex mitochondrial evolution.

AB - Arterial stiffness may contribute to the pathogenesis of hypertension. The goal of this study is to elucidate the role of Endothelin-1 (ET-1) in aortic stiffening-induced hypertension through ETA receptor activation. An increase in aortic stiffness was created by use of a non-constrictive restraint, NCR on the abdominal aortic surface. A group of rats underwent aortic NCR or sham operation for 12 weeks and were then treated with ETA receptor antagonist BQ-123 for 3 weeks. We found that 12 weeks of aortic NCR significantly increased pulse and mean pressure and altered peripheral flow pattern, accompanied by an increased serum ET-1 level (p < 0.05). The increase in aortic stiffness (evidenced by an elevated pulse wave velocity) caused hypertrophic structural remodeling and decreased arterial compliance, along with an impaired endothelial function in peripheral small arteries. BQ-123 treatment only partially attenuated peripheral arterial hypertrophy and restored arterial compliance, but completely recovered endothelium function, and consequently restored local flow and lowered blood pressure. Our findings underscore the hemodynamic coupling between aortic stiffening and peripheral arterial vessels and flow dynamics through an ETA dependent mechanism. ETA receptor blockade may have therapeutic potential for improving peripheral vessel structure and function in the treatment of aortic stiffness-induced hypertension.

Numerical analysis shows a 50-period InN/GaN DA yields minibands that are densely quantized by numerous confined states. Interband transitions between the conduction and valence minibands create ultra-broadband optical gain spectra with bandwidths up to ~1 MUm that can be tuned from the red to infrared. In addition, the ultra-broadband optical gain, bandwidth, and spectral coverage of the III-Nitride DA is very sensitive to layer thickness and other structural design parameters. This study shows the promising potential of the III-Nitride DAs with tunable ultra-broadband interband optical gain for use in semiconductor optical amplifiers and future III-Nitride photonic integration applications. PMID- 29449621 TI - Polygonum aviculare L. extract and quercetin attenuate contraction in airway smooth muscle. AB - Because of the serious side effects of the currently used bronchodilators, new compounds with similar functions must be developed. We screened several herbs and found that Polygonum aviculare L. contains ingredients that inhibit the precontraction of mouse and human airway smooth muscle (ASM). High K+-induced precontraction in ASM was completely inhibited by nifedipine, a selective blocker of L-type voltage-dependent Ca2+ channels (LVDCCs). However, nifedipine only partially reduced the precontraction induced by acetylcholine chloride (ACH). Additionally, the ACH-induced precontraction was partly reduced by pyrazole-3 (Pyr3), a selective blocker of TRPC3 and stromal interaction molecule (STIM)/Orai channels. These channel-mediated currents were inhibited by the compounds present in P. aviculare extracts, suggesting that this inhibition was mediated by LVDCCs, TRPC3 and/or STIM/Orai channels. Moreover, these channel-mediated currents were inhibited by quercetin, which is present in P. aviculare extracts. Furthermore, quercetin inhibited ACH-induced precontraction in ASM. Overall, our data indicate that the ethyl acetate fraction of P. aviculare and quercetin can inhibit Ca2+ permeant LVDCCs, TRPC3 and STIM/Orai channels, which inhibits the precontraction of ASM. These findings suggest that P. aviculare could be used to develop new bronchodilators to treat obstructive lung diseases such as asthma and chronic obstructive pulmonary disease. PMID- 29449622 TI - Directional preparation of anticoagulant-active sulfated polysaccharides from Enteromorpha prolifera using artificial neural networks. AB - The sulfated polysaccharides from Enteromorpha prolifera (PE) are a potential source of anticoagulant agents. In this study, the PE was degraded by specific degradase and five hydrolysis products with different molecular weights were prepared. The product of 206 kDa is a kind of high rhamnose-containing polysaccharide with sulfate ester (34.29%). It could effectively prolong the activated partial thromboplastin time (APTT), which indicated inhibition of the intrinsic coagulation pathway. The artificial neural network (ANN) was built to realize the directional preparation of anticoagulant-active polysaccharides. Based on monitoring glucose concentration on-line, a visualization system of enzymatic hydrolysis was developed to simplify the operation of ANN. The model could be further applied to predict molecular weights of polysaccharides that possess diverse biological activities. PMID- 29449623 TI - Targeted disruption of the iNOS gene improves adipose tissue inflammation and fibrosis in leptin-deficient ob/ob mice: role of tenascin C. AB - BACKGROUND/OBJECTIVES: Obesity is related to a dynamic extracellular matrix (ECM) remodeling, which involves the synthesis and degradation of different proteins, such as tenascin C (TNC) in the adipose tissue (AT). Given the functional relationship between leptin and inducible nitric oxide synthase (iNOS), our aim was to analyze the impact of the absence of the iNOS gene in AT inflammation and ECM remodeling in ob/ob mice. SUBJECTS/METHODS: The expression of genes involved in inflammation and ECM remodeling was evaluated in 10-week-old male double knockout (DBKO) mice simultaneously lacking the ob and iNOS genes as well as in ob/ob mice classified into three groups [control, leptin-treated (1 mg kg-1 day 1) and pair-fed]. RESULTS: Leptin deficiency increased inflammation and fibrosis in AT. As expected, leptin treatment improved the obesity phenotype. iNOS deficiency in ob/ob mice improved insulin sensitivity, AT inflammation, and ECM remodeling, as evidenced by lower AT macrophage infiltration and collagen deposition, a downregulation of proinflammatory and profibrogenic genes Tnf, Emr1, Hif1a, Col6a1, Col6a3, and Tnc, as well as lower circulating TNC levels. Interestingly, leptin upregulated TNC expression and release in 3T3-L1 adipocytes, and iNOS knockdown in 3T3-L1 fat cells produced a significant decrease in basal and leptin-induced Tnc expression. CONCLUSIONS: Ablation of iNOS in leptin-deficient mice improved AT inflammation and ECM remodeling-related genes, attenuating fibrosis, and metabolic dysfunction. The activation of iNOS by leptin is necessary for the synthesis and secretion of TNC in adipocytes, suggesting an important role of this alarmin in the development of AT inflammation and fibrosis.

AB - A water droplet pinning on inclined hydrophobic surface is considered and the droplet heat transfer characteristics are examined. Solution crystallization of polycarbonate is carried out to create hydrophobic characteristics on the surface. The pinning state of the water droplet on the extreme inclined hydrophobic surface (0 degrees <= delta <= 180 degrees , delta being the inclination angle) is assessed. Heat transfer from inclined hydrophobic surface to droplet is simulated for various droplet volumes and inclination angles in line with the experimental conditions. The findings revealed that the hydrophobic surface give rise to large amount of air being trapped within texture, which generates Magdeburg like forces between the droplet meniscus and the textured surface while contributing to droplet pinning at extreme inclination angles. Two counter rotating cells are developed for inclination angle in the range of 0 degrees < delta < 20 degrees and 135 degrees < delta < 180 degrees ; however, a single circulation cell is formed inside the droplet for inclination angle of 25 degrees <= delta <= 135 degrees . The Nusselt number remains high for the range of inclination angle of 45 degrees <= delta <= 135 degrees . Convection and conduction heat transfer enhances when a single and large circulation cell is formed inside the droplet. PMID- 29449625 TI - Toll-like receptor 4 modulation influences human neural stem cell proliferation and differentiation. AB - Toll-like receptor 4 (TLR4) activation is pivotal to innate immunity and has been shown to regulate proliferation and differentiation of human neural stem cells (hNSCs) in vivo. Here we study the role of TLR4 in regulating hNSC derived from the human telencephalic-diencephalic area of the fetal brain and cultured in vitro as neurospheres in compliance with Good Manifacture Procedures (GMP) guidelines. Similar batches have been used in recent clinical trials in ALS patients. We found that TLR2 and 4 are expressed in hNSCs as well as CD14 and MD 2 co-receptors, and TLR4 expression is downregulated upon differentiation. Activation of TLR4 signaling by lipopolysaccharide (LPS) has a positive effect on proliferation and/or survival while the inverse is observed with TLR4 inhibition by a synthetic antagonist. TLR4 activation promotes neuronal and oligodendrocyte differentiation and/or survival while TLR4 inhibition leads to increased apoptosis. Consistently, endogenous expression of TLR4 is retained by hNSC surviving after transplantation in ALS rats or immunocompromised mice, thus irrespectively of the neuroinflammatory environment. The characterization of downstream signaling of TLR4 in hNSCs has suggested some activation of the inflammasome pathway. This study suggests TLR4 signaling as essential for hNSC self-renewal and as a novel target for the study of neurogenetic mechanisms. PMID- 29449626 TI - Molecular dynamics study of strengthening mechanism of nanolaminated graphene/Cu composites under compression. AB - Molecular dynamics simulations of nanolaminated graphene/Cu (NGCu) and pure Cu under compression are conducted to investigate the underlying strengthening mechanism of graphene and the effect of lamella thickness. It is found that the stress-strain curves of NGCu undergo 3 regimes i.e. the elastic regime I, plastic strengthening regime II and plastic flow regime III. Incorporating graphene monolayer is proved to simultaneously contribute to the strength and ductility of the composites and the lamella thickness has a great effect on the mechanical properties of NGCu composites. Different strengthening mechanisms play main role in different regimes, the transition of mechanisms is found to be related to the deformation behavior. Graphene affected zone is developed and integrated with rule of mixtures and confined layer slip model to describe the elastic properties of NGCu and the strengthening effect of the incorporated graphene. PMID- 29449627 TI - Measurements of complex refractive index change of photoactive yellow protein over a wide wavelength range using hyperspectral quantitative phase imaging. AB - A novel optical holographic technique is presented to simultaneously measure both the real and imaginary components of the complex refractive index (CRI) of a protein solution over a wide visible wavelength range. Quantitative phase imaging was employed to precisely measure the optical field transmitted from a protein solution, from which the CRIs of the protein solution were retrieved using the Fourier light scattering technique. Using this method, we characterized the CRIs of the two dominant structural states of a photoactive yellow protein solution over a broad wavelength range (461-582 nm). The significant CRI deviation between the two structural states was quantified and analysed. The results of both states show the similar overall shape of the expected rRI obtained from the Kramers Kronig relations.

PMID- 29449631 TI - Electrochemical Performance of Supercapacitor with Stacked Copper Foils Coated with Graphene Nanoplatelets. AB - The energy density of conventional supercapacitors is in the range of 6-10 Wh kg 1, which has restricted them from many applications that require devices with long durations. Herein, we report a method for enhancing the energy density of a device through the parallel stacking of five copper foils coated on each side with graphene nanoplatelets. Microporous papers immersed in 2 M aqueous sodium sulphate were used as separators. With a low contact resistance of 0.05 Omega, the supercapacitor yielded an optimum specific energy density and a specific power density of 24.64 Wh kg-1 and 402 W kg-1 at 0.8 V, respectively. The working potential was increased to 2.4 V when three of the supercapacitors were connected in series, forming a tandem device. Its potential for real applications was manifested by the ability to light up a light-emitting diode for 40 s after charging for 60 s. PMID- 29449632 TI - Inducible nitric oxide synthase during the late phase of sepsis is associated with hypothermia and immune cell migration. AB - Hypothermia is a significant sign of sepsis, which is associated with poor prognosis, but few mechanisms underlying the regulation of hypothermia are known. Inducible nitric oxide synthase (iNOS) is a key inflammatory mediator of sepsis. However, the therapeutic benefit of iNOS inhibition in sepsis is still controversial, and requires elucidation in an accurate model system. In this study, wild-type (WT) mice showed temperature drops in a biphasic manner at the early and late phase of sepsis, and all mice died within 48 h of sepsis. In contrast, iNOS-knockout (KO) mice never showed the second temperature drop and exhibited improved mortality. Plasma nitric oxide (NO) levels of WT mice increased in the late phase of sepsis and correlated to hypothermia. The results indicate that iNOS-derived NO during the late phase of sepsis caused vasodilation induced hypothermia and a lethal hypodynamic state. The expression of the iNOS mRNA was high in the lung of WT mice with sepsis, which reflects the pathology of acute respiratory distress syndrome (ARDS). We obtained the results in a modified keyhole-type cecal ligation and puncture model of septic shock induced by minimally invasive surgery. In this accurate and reproducible model system, we transplanted the bone marrow cells of GFP transgenic mice into WT and iNOS-KO mice, and evaluated the role of increased pulmonary iNOS expression in cell migration during the late phase of sepsis. We also investigated the quantity and type of bone marrow-derived cells (BMDCs) in the lung. The number of BMDCs in the lung of iNOS-KO mice was less than that in the lung of WT mice. The major BMDCs populations were CD11b-positive, iNOS-negative cells in WT mice, and Gr-1 positive cells in iNOS-KO mice that expressed iNOS. These results suggest that sustained hypothermia may be a beneficial guide for future iNOS-targeted therapy of sepsis, and that iNOS modulated the migratory efficiency and cell type of BMDCs in septic ARDS. PMID- 29449633 TI - A competitive cell-permeable peptide impairs Nme-1 (NDPK-A) and Prune-1 interaction: therapeutic applications in cancer. AB - The understanding of protein-protein interactions is crucial in order to generate a second level of functional genomic analysis in human disease. Within a cellular microenvironment, protein-protein interactions generate new functions that can be defined by single or multiple modes of protein interactions. We outline here the clinical importance of targeting of the Nme-1 (NDPK-A)-Prune-1 protein complex in cancer, where an imbalance in the formation of this protein-protein complex can result in inhibition of tumor progression. We discuss here recent functional data using a small synthetic competitive cell-permeable peptide (CPP) that has shown therapeutic efficacy for impairing formation of the Nme-1-Prune-1 protein complex in mouse preclinical xenograft tumor models (e.g., breast, prostate, colon, and neuroblastoma). We thus believe that further discoveries in the near future related to the identification of new protein-protein interactions will have great impact on the development of new therapeutic strategies against various cancers. PMID- 29449630 TI - Prime and Boost Vaccination Elicit a Distinct Innate Myeloid Cell Immune Response. AB - Understanding the innate immune response to vaccination is critical in vaccine design. Here, we studied blood innate myeloid cells after first and second immunization of cynomolgus macaques with the modified vaccinia virus Ankara. The inflammation at the injection site was moderate and resolved faster after the boost. The blood concentration of inflammation markers increased after both injections but was lower after the boost. The numbers of neutrophils, monocytes, and dendritic cells were transiently affected by vaccination, but without any major difference between prime and boost. However, phenotyping deeper those cells with mass cytometry unveiled their high phenotypic diversity with subsets responding differently after each injection, some enriched only after the primary injection and others only after the boost. Actually, the composition in subphenotype already differed just before the boost as compared to just before the prime. Multivariate analysis identified the key features that contributed to these differences. Cell subpopulations best characterizing the post-boost response were more activated, with a stronger expression of markers involved in phagocytosis, antigen presentation, costimulation, chemotaxis, and inflammation. This study revisits innate immunity by demonstrating that, like adaptive immunity, innate myeloid responses differ after one or two immunizations. PMID- 29449634 TI - Self-perceptions from people with Down syndrome in Japan. AB - Self-perception of people with Down Syndrome (DS) was originally studied in the United States in 2011; this study indicated that 99% of people with DS are happy with their lives. In this study, we investigated self-perceptions of people with DS in Japan and compared the results to the previous study made in the United States. The participants (n = 300) were 12 years old or older and members of Japan Down Syndrome Society (JDS). The questionnaire was collected between 30 October 2015 and 26 November 2015. Of 96(32%) responses, 76 (97%) agreed they are happy with their lives. We found that most people with DS in Japan also feel positive about themselves and their lives. Along with the start of Non-Invasive Prenatal Testing in Japan, DS draws an attention from Japanese people because maternal age has been increasing. This has resulted in the growth of the number of prenatal tests marketed in Japan. Therefore, we expect our results to be relevant to genetic counseling for the couples considering prenatal tests or parents raising their children with DS so that they have a clearer image about life with DS and can better visualize their life plans. PMID- 29449635 TI - Purkinje cells derived from TSC patients display hypoexcitability and synaptic deficits associated with reduced FMRP levels and reversed by rapamycin. AB - Accumulating evidence suggests that cerebellar dysfunction early in life is associated with autism spectrum disorder (ASD), but the molecular mechanisms underlying the cerebellar deficits at the cellular level are unclear. Tuberous sclerosis complex (TSC) is a neurocutaneous disorder that often presents with ASD. Here, we developed a cerebellar Purkinje cell (PC) model of TSC with patient derived human induced pluripotent stem cells (hiPSCs) to characterize the molecular mechanisms underlying cerebellar abnormalities in ASD and TSC. Our results show that hiPSC-derived PCs from patients with pathogenic TSC2 mutations displayed mTORC1 pathway hyperactivation, defects in neuronal differentiation and RNA regulation, hypoexcitability and reduced synaptic activity when compared with those derived from controls. Our gene expression analyses revealed downregulation of several components of fragile X mental retardation protein (FMRP) targets in TSC2-deficient hiPSC-PCs. We detected decreased expression of FMRP, glutamate receptor delta2 (GRID2), and pre- and post-synaptic markers such as synaptophysin and PSD95 in the TSC2-deficient hiPSC-PCs. The mTOR inhibitor rapamycin rescued the deficits in differentiation, synaptic dysfunction, and hypoexcitability of TSC2 mutant hiPSC-PCs in vitro. Our findings suggest that these gene expression changes and cellular abnormalities contribute to aberrant PC function during development in TSC affected individuals. PMID- 29449636 TI - Structural elucidation of a polysaccharide from Flammulina velutipes and its immunomodulation activities on mouse B lymphocytes. AB - A novel polysaccharide FVPB2 was purified from fruiting bodies of Flammulina velutipes. Its structure was elucidated by monosaccharide composition and methylation analyses, UV-Visible and FTIR spectroscopy as well as NMR. FVPB2 was a homogeneous heteropolysaccharide (molecular weight ~ 1.50 * 104 Da) containing D-galactose, D-mannose, L-fucose, and D-glucose at molar ratio of 1.9:1.2:1:2.5. In vitro immunomodulatory studies showed FVPB2 induced proliferation of mouse spleen lymphocytes in a dose-dependent manner. The levels of IgM and IgG, secreted by B cells, increased after FVPB2 treatment. So FVPB2 has potential to be a new important immunomodulatory nutraceutical. PMID- 29449637 TI - Facile emulsion mediated synthesis of phase-pure diopside nanoparticles. AB - Diopside is a common natural pyroxene that is rarely found in a pure state, since magnesium is often partially substituted by iron, and other elements (sodium and aluminum) are often present. This pyroxene, along with feldspars and olivines, is common in concrete. As the prospective license renewal of light water reactors to 80 years of operation has raised concerns on the effects of radiation in the concrete biological shield surrounding the reactors, mineral nanoparticles can be valuable to perform amorphization studies to inform predictive models of mechanical properties of irradiated concrete. The synthesis of diopside nanoparticles was achieved in this study using a reverse-micelle sol-gel method employing TEOS, calcium chloride and Mg(MeO)2 in a methanol/toluene solution. Tert-butylamine and water were used as hydrolysis agents, and dodecylamine as a surfactant. The resulting amorphous precursor was centrifuged to remove organics and fired at 800 degrees C. Additional reaction with hydrogen peroxide was used to remove amine remnants. TEM and SEM examinations revealed a product comprised of 50-100 nm diameter nanoparticles. XRD indicated phase pure diopside and BET indicated a surface area of 63.5 m2/g before peroxide treatment, which at a bulk density of 3.4 g/cm3 is equivalent to particles with diameter of 28 nm. PMID- 29449638 TI - Protection from experimental cerebral malaria with a single intravenous or subcutaneous whole-parasite immunization. AB - Cerebral malaria is a life-threatening complication of Plasmodia infection and a major cause of child mortality in Sub-Saharan Africa. We report that protection from experimental cerebral malaria in the rodent model is obtained by a single intravenous or subcutaneous whole-parasite immunization. Whole-parasite immunization with radiation-attenuated sporozoites was equally protective as immunization with non-attenuated sporozoites under chemoprophylaxis. Both immunization regimens delayed the development of blood-stage parasites, but differences in cellular and humoral immune mechanisms were observed. Single-dose whole-parasite vaccination might serve as a relatively simple and feasible immunization approach to prevent life-threatening cerebral malaria. PMID- 29449639 TI - A hERG mutation E1039X produced a synergistic lesion on IKs together with KCNQ1 R174C mutation in a LQTS family with three compound mutations. AB - Congenital long QT syndrome (LQTS) caused by compound mutations is usually associated with more severe clinical phenotypes. We identified a LQTS family harboring three compound mutations in different genes (KCNQ1-R174C, hERG-E1039X and SCN5A-E428K). KCNQ1-R174C, hERG-E1039X and SCN5A-E428K mutations and/or relevant wild-type (WT) cDNAs were respectively expressed in mammalian cells. IKs like, IKr-like, INa-like currents and the functional interaction between KCNQ1 R174C and hERG-E1039X channels were studied using patch-clamp and immunocytochemistry techniques. (1) Expression of KCNQ1-R174C alone showed no IKs. Co-expression of KCNQ1-WT + KCNQ1-R174C caused a loss-of-function in IKs and blunted the activation of IKs in response to isoproterenol. (2) Expression of hERG-E1039X alone and co-expression of hERG-WT + hERG-E1039X negatively shifted inactivation curves and decelerated the recovery time from inactivation. (3) Expression of SCN5A-E428K increased peak INa, but had no effect on late INa. (4) IKs and IKr interact, and hERG-E1039X caused a loss-of-function in IKs. (5) Immunocytochemical studies indicated that KCNQ1-R174C is trafficking defective and hERG-E1039X is defective in biosynthesis/degradation, but the abnormities were rescued by co-expression with WT. Thus, KCNQ1-R174C and hERG-E1039X disrupted IKs and IKr functions, respectively. The synergistic lesion, caused by KCNQ1-R174C and hERG-E1039X in IKs, is very likely why patients showed more severe phenotypes in the compound mutation case.

AB - A new Zn-cluster based MOF, [Zn21(BTC)11(MU3-OH)3(MU4-O)3(H2O)18].21EtOH (1) (H3BTC = 1,3,5-benzenetricarboxylic acid), with two different types of cluster nodes has been successfully synthesized from Zn2+ and H3BTC under the solvothermal conditions. Single crystal X-ray diffraction studies reveal that 1 is a 3D trinodal (3,5,6)-c framework which features a large octahedral cage organized by nine Zn3O and nine Zn4O clusters SBUs and twenty-four triangular BTC3- linkers. The Eu3+/Tb3+-incorporated derivative of 1 with 0.251% Eu3+ and 0.269% Tb3+ exhibits tunable luminescence from yellow to white and then to blue green by changing the excitation wavelength from 308 to 315 nm. Metal ion exchange with Cu2+ affords isomorphous Cu-based MOF with enhanced N2 and CO2 adsorption capacity. In addition, 1 can act as a selective luminescent sensor for Cu2+ and Al3+ ions. PMID- 29449642 TI - NIT1 suppresses tumour proliferation by activating the TGFbeta1-Smad2/3 signalling pathway in colorectal cancer. AB - NIT1 protein has been reported to be a potential tumour suppressor in tumour progression. However, little is known about the specific role of NIT1 in tumour development and progression. In this study, we confirmed the specific effects of NIT1 in the regulation of colorectal carcinoma cell proliferation. Here, we showed that NIT1 was significantly downregulated in colorectal cancer tissues compared with that in adjacent normal tissues. The decreased expression of NIT1 was significantly correlated with poor differentiation and more serosal invasion. Functional experiments showed that NIT1 inhibited CRC cell growth both in vitro and in vivo. NIT1 induced cell cycle arrest and apoptosis. Furthermore, NIT1 recruited Smad2/3 to the TGFbeta receptor and activated the TGFbeta-Smad2/3 pathway by interacting with SARA and SMAD2/3 in CRC. Further study has shown that SMAD3 directly binds to the promoter regions of NIT1 and enhances the transcription of NIT1. Together, our findings indicate that NIT1 suppresses CRC proliferation through a positive feedback loop between NIT1 and activation of the TGFbeta-Smad signalling pathway. This study might provide a new promising strategy for CRC. PMID- 29449643 TI - SIRT2 regulates oxidative stress-induced cell death through deacetylation of c Jun NH2-terminal kinase. AB - c-Jun NH2-terminal kinases (JNKs) are responsive to stress stimuli and their activation regulate key cellular functions, including cell survival, growth, differentiation and aging. Previous studies demonstrate that activation of JNK requires dual phosphorylation by the mitogen-activated protein kinase kinases. However, other post-translational mechanisms involved in regulating the activity of JNK have been poorly understood. In this work, we studied the functional significance of reversible lysine acetylation in regulating the kinase activity of JNK. We found that the acetyl transferase p300 binds to, acetylates and inhibits kinase activity of JNK. Using tandem mass spectrometry, molecular modelling and molecular dynamics simulations, we found that acetylation of JNK at Lys153 would hinder the stable interactions of the negatively charged phosphates and prevent the adenosine binding to JNK. Our screening for the deacetylases found SIRT2 as a deacetylase for JNK. Mechanistically, SIRT2-dependent deacetylation enhances ATP binding and enzymatic activity of JNK towards c-Jun. Furthermore, SIRT2-mediated deacetylation favours the phosphorylation of JNK by MKK4, an upstream kinase. Our results indicate that deacetylation of JNK by SIRT2 promotes oxidative stress-induced cell death. Conversely, SIRT2 inhibition attenuates H2O2-mediated cell death in HeLa cells. SIRT2-deficient (SIRT2-KO) mice exhibit increased acetylation of JNK, which is associated with markedly reduced catalytic activity of JNK in the liver. Interestingly, SIRT2-KO mice were resistant to acetaminophen-induced liver toxicity. SIRT2-KO mice show lower cell death, minimal degenerative changes, improved liver function and survival following acetaminophen treatment. Overall, our work identifies SIRT2-mediated deacetylation of JNK as a critical regulator of cell survival during oxidative stress. PMID- 29449645 TI - EGFR-PI3K-PDK1 pathway regulates YAP signaling in hepatocellular carcinoma: the mechanism and its implications in targeted therapy. AB - The epidermal growth factor receptor (EGFR) pathway and Hippo signaling play an important role in the carcinogenesis of hepatocellular carcinoma (HCC). However, the crosstalk between these two pathways and its implications in targeted therapy remains unclear. We found that the activated EGFR signaling could bypass RhoA to promote the expression of YAP(Yes-associated protein), the core effector of the Hippo signaling, and its downstream target Cyr61. Further studies indicated that EGFR signaling mainly acted through the PI3K-PDK1 (Phosphoinositide 3-kinase Phosphoinositide-dependent kinase-1) pathway to activate YAP, but not the AKT and MAPK pathways. While YAP knockdown hardly affected the EGFR signaling. In addition, EGF could promote the proliferation of HCC cells in a YAP-independent manner. Combined targeting of YAP and EGFR signaling by simvastatin and the EGFR signaling inhibitors, including the EGFR tyrosine kinase inhibitor (TKI) gefitinib, the RAF inhibitor sorafenib and the MEK inhibitor trametinib, presented strong synergistic cytotoxicities in HCC cells. Therefore, the EGFR PI3K-PDK1 pathway could activate the YAP signaling, and the activated EGFR signaling could promote the HCC cell growth in a YAP-independent manner. Combined use of FDA-approved inhibitors to simultaneously target YAP and EGFR signaling presented several promising therapeutic approaches for HCC treatment. PMID- 29449644 TI - Inhibition of the JNK/MAPK signaling pathway by myogenesis-associated miRNAs is required for skeletal muscle development. AB - Skeletal muscle differentiation is controlled by multiple cell signaling pathways, however, the JNK/MAPK signaling pathway dominating this process has not been fully elucidated. Here, we report that the JNK/MAPK pathway was significantly downregulated in the late stages of myogenesis, and in contrast to P38/MAPK pathway, it negatively regulated skeletal muscle differentiation. Based on the PAR-CLIP-seq analysis, we identified six elevated miRNAs (miR-1a-3p, miR 133a-3p, miR-133b-3p, miR-206-3p, miR-128-3p, miR-351-5p), namely myogenesis associated miRNAs (mamiRs), negatively controlled the JNK/MAPK pathway by repressing multiple factors for the phosphorylation of the JNK/MAPK pathway, including MEKK1, MEKK2, MKK7, and c-Jun but not JNK protein itself, and as a result, expression of transcriptional factor MyoD and mamiRs were further promoted. Our study revealed a novel double-negative feedback regulatory pattern of cell-specific miRNAs by targeting phosphorylation kinase signaling cascade responsible for skeletal muscle development. PMID- 29449646 TI - Assessing cetacean surveys throughout the Mediterranean Sea: a gap analysis in environmental space. AB - Heterogeneous data collection in the marine environment has led to large gaps in our knowledge of marine species distributions. To fill these gaps, models calibrated on existing data may be used to predict species distributions in unsampled areas, given that available data are sufficiently representative. Our objective was to evaluate the feasibility of mapping cetacean densities across the entire Mediterranean Sea using models calibrated on available survey data and various environmental covariates. We aggregated 302,481 km of line transect survey effort conducted in the Mediterranean Sea within the past 20 years by many organisations. Survey coverage was highly heterogeneous geographically and seasonally: large data gaps were present in the eastern and southern Mediterranean and in non-summer months. We mapped the extent of interpolation versus extrapolation and the proportion of data nearby in environmental space when models calibrated on existing survey data were used for prediction across the entire Mediterranean Sea. Using model predictions to map cetacean densities in the eastern and southern Mediterranean, characterised by warmer, less productive waters, and more intense eddy activity, would lead to potentially unreliable extrapolations. We stress the need for systematic surveys of cetaceans in these environmentally unique Mediterranean waters, particularly in non-summer months. PMID- 29449647 TI - The pro-inflammatory phenotype of the human non-classical monocyte subset is attributed to senescence. AB - Human primary monocytes comprise a heterogeneous population that can be classified into three subsets based on CD14 and CD16 expression: classical (CD14high/CD16-), intermediate (CD14high/CD16+), and non-classical (CD14low/CD16+). The non-classical monocytes are the most pro-inflammatory in response to TLR stimulation in vitro, yet they express a remarkably high basal level of miR-146a, a microRNA known to negatively regulate the TLR pathway. This concurrence of a pro-inflammatory status and a high miR-146a level has been associated with cellular senescence in other cell types. Hence, we assessed the three monocyte subsets for evidence of senescence, including proliferative status, telomere length, cellular ROS levels, and mitochondrial membrane potential. Indeed, the non-classical subset exhibited the clearest hallmarks of senescence, followed by the intermediate and then the classical subset. In addition, the non-classical subset secreted pro-inflammatory cytokines basally in vitro. The highly pro-inflammatory nature of the non-classical monocytes could be a manifestation of the senescence-associated secretory phenotype (SASP), likely induced by a high basal NF-kappaB activity and IL-1alpha production. Finally, we observed an accumulation of the non-classical monocytes, in conjunction with higher levels of plasma TNF-alpha and IL-8, in the elderly. These factors may contribute to inflamm-aging and age-related inflammatory conditions, such as atherosclerosis and osteoarthritis. With our new understanding that the non classical monocyte subset is a senescent population, we can now re-examine the role of this subset in disease conditions where this subset expands. PMID- 29449648 TI - The role of disease-linked residue glutamine-913 in support of the structure and function of the human electrogenic sodium/bicarbonate cotransporter NBCe1-A. AB - Mutations in the sodium bicarbonate cotransporter NBCe1 (SLC4A4) cause proximal renal tubular acidosis (pRTA). We recently described a novel pRTA mutation p.Gln913Arg (Q913R), inherited in compound heterozygous form with p.Arg510His (R510H). Q913R causes intracellular retention of NBCe1 and a 'gain of function' Cl- leak. To learn more about the importance of glutamine at position 913, we substituted a variety of alternative amino-acid residues (Cys, Glu, Lys, Leu, Ser) at position 913. Studying cRNA-injected Xenopus oocytes by voltage clamp, we find that most de novo mutants exhibit close-to-normal NBCe1 activity; only Q913K expresses a Cl- leak. Studying transiently-transfected, polarised kidney cells by fluorescence microscopy we find that most de novo mutants (except Q913E) are intracellularly retained. A 3D homology model predicts that Gln913 is located in the gating domain of NBCe1 and neighbours the 3D space occupied by another pRTA associated residue (Arg881), highlighting an important and conformationally sensitive region of NBCe1. We conclude that the intracellular retention of Q913R is caused by the loss of Gln at position 913, but that the manifestation of the Cl- leak is related to the introduction of Arg at position 913. Our findings will inform future studies to elucidate the nature and the consequences of the leak. PMID- 29449649 TI - Predicting sex from brain rhythms with deep learning. AB - We have excellent skills to extract sex from visual assessment of human faces, but assessing sex from human brain rhythms seems impossible. Using deep convolutional neural networks, with unique potential to find subtle differences in apparent similar patterns, we explore if brain rhythms from either sex contain sex specific information. Here we show, in a ground truth scenario, that a deep neural net can predict sex from scalp electroencephalograms with an accuracy of >80% (p < 10-5), revealing that brain rhythms are sex specific. Further, we extracted sex-specific features from the deep net filter layers, showing that fast beta activity (20-25 Hz) and its spatial distribution is a main distinctive attribute. This demonstrates the ability of deep nets to detect features in spatiotemporal data unnoticed by visual assessment, and to assist in knowledge discovery. We anticipate that this approach may also be successfully applied to other specialties where spatiotemporal data is abundant, including neurology, cardiology and neuropsychology. PMID- 29449650 TI - The transition from dental school to postgraduate dental foundation training: strengthening the interaction between stakeholders. AB - This article demonstrates the benefits of collaboration between dental educators in undergraduate and postgraduate settings, to facilitate the transition of dental students into dental foundation training (DFT). The School of Dental Sciences at Newcastle University and Health Education England, working across north-east and north Cumbria, have strengthened links by forming a dental foundation programme undergraduate liaison group (FPUG) involving all stakeholders. The group has shared information between the organisations, enhanced stakeholder engagement, and developed several initiatives including workshops to help prepare final year students for the transition to DFT. A small investment in time has been highly effective, and the formation of a similar group merits consideration in other areas of the UK. PMID- 29449652 TI - Serious concerns about the General Dental Council's performance and its direction of travel. AB - There should be tension between a profession and its regulator, it would be odd if it were not so, but the level of concern that has been articulated recently by some high profile commentators about that relationship has been well beyond what I would describe as tension. In this piece I attempt to contextualise my personal observations and comments on what is rapidly becoming a serious concern among those few of us who have had to deal with the profession: regulator interface at the highest level. PMID- 29449651 TI - Beyond Streptococcus mutans: clinical implications of the evolving dental caries aetiological paradigms and its associated microbiome. AB - Aetiological concepts of dental caries have evolved over the years from being considered as a disease initiated by nonspecific microorganisms, to being regarded as an 'infectious' disease caused by specific bacteria, to the current paradigms that emphasise a 'mixed bacterial-ecological approach' as being responsible for lesion initiation and pathogenesis. These aetiological paradigms are not just intellectual concepts but have important implications on how clinicians manage this age-old disease in the twenty-first century. Despite evidence-backed recommendations for adopting more biological measures to counter the disease, a significant proportion of dentists continue following traditional caries management guidelines in their daily clinical practice. This paper will review the evolving dental caries aetiological concepts and highlight the current evidence for adopting a more ecological approach to caries prevention, risk assessment, and treatment. PMID- 29449653 TI - CFTR mutation enhances Dishevelled degradation and results in impairment of Wnt dependent hematopoiesis. AB - Mutations of cystic fibrosis transmembrane conductance regulator (CFTR) cause cystic fibrosis (CF) with a multitude of clinical manifestations. Some CF patients develop clinically significant anemia, suggesting that CFTR may regulate hematopoiesis. Here, we report that cftr mutant zebrafish model exhibits primitive and definitive hematopoietic defects with impaired Wnt signaling. Cftr is found to interact, via its PDZ-binding domain (PDZBD), with Dishevelled (Dvl), a key component of Wnt signaling required for hematopoietic progenitor specification, thus protecting Dvl from Dapper1 (Dpr1)-induced lysosomal degradation. Defective hematopoiesis and impaired Wnt signaling in cftr mutant can be rescued by overexpression of wild-type or channel function-defective G551D mutant CFTR with an intact PDZBD, but not Cftr with mutations in the PDZBD. Analysis of human database ( http://r2.amc.nl ) shows that CFTR is positively correlated with DVL2 and Wnt-related hematopoietic factors in human blood system. The results reveal a previously unrecognized role of CFTR, which is independent of its channel function, in regulating DVL degradation and thus Wnt signaling required for hematopoiesis in both zebrafish and humans, providing an explanation for the anemic phenotype of CF patients. PMID- 29449655 TI - Observationally quantified reconnection providing a viable mechanism for active region coronal heating. AB - The heating of the Sun's corona has been explained by several different mechanisms including wave dissipation and magnetic reconnection. While both have been shown capable of supplying the requisite power, neither has been used in a quantitative model of observations fed by measured inputs. Here we show that impulsive reconnection is capable of producing an active region corona agreeing both qualitatively and quantitatively with extreme-ultraviolet observations. We calculate the heating power proportional to the velocity difference between magnetic footpoints and the photospheric plasma, called the non-ideal velocity. The length scale of flux elements reconnected in the corona is found to be around 160 km. The differential emission measure of the model corona agrees with that derived using multi-wavelength images. Synthesized extreme-ultraviolet images resemble observations both in their loop-dominated appearance and their intensity histograms. This work provides compelling evidence that impulsive reconnection events are a viable mechanism for heating the corona. PMID- 29449656 TI - Ultrasound beam steering of oxygen nanobubbles for enhanced bladder cancer therapy. AB - New intravesical treatment approaches for bladder cancer are needed as currently approved treatments show several side effects and high tumor recurrence rate. Our study used MB49 murine urothelial carcinoma model to evaluate oxygen encapsulated cellulosic nanobubbles as a novel agent for imaging and ultrasound guided drug delivery. In this study, we show that oxygen nanobubbles (ONB) can be propelled (up to 40 mm/s) and precisely guided in vivo to the tumor by an ultrasound beam. Nanobubble velocity can be controlled by altering the power of the ultrasound Doppler beam, while nanobubble direction can be adjusted to different desired angles by altering the angle of the beam. Precise ultrasound beam steering of oxygen nanobubbles was shown to enhance the efficacy of mitomycin-C, resulting in significantly lower tumor progression rates while using a 50% lower concentration of chemotherapeutic drug. Further, dark field imaging was utilized to visualize and quantify the ONB ex vivo. ONBs were found to localize up to 500 um inside the tumor using beam steering. These results demonstrate the potential of an oxygen nanobubble drug encapsulated system to become a promising strategy for targeted drug delivery because of its multimodal (imaging and oxygen delivery) and multifunctional (targeting and hypoxia programming) properties. PMID- 29449654 TI - Analysis combining correlated glaucoma traits identifies five new risk loci for open-angle glaucoma. AB - Open-angle glaucoma (OAG) is a major cause of blindness worldwide. To identify new risk loci for OAG, we performed a genome-wide association study in 3,071 OAG cases and 6,750 unscreened controls, and meta-analysed the results with GWAS data for intraocular pressure (IOP) and optic disc parameters (the overall meta analysis sample size varying between 32,000 to 48,000 participants), which are glaucoma-related traits. We identified and independently validated four novel genome-wide significant associations within or near MYOF and CYP26A1, LINC02052 and CRYGS, LMX1B, and LMO7 using single variant tests, one additional locus (C9) using gene-based tests, and two genetic pathways - "response to fluid shear stress" and "abnormal retina morphology" - in pathway-based tests. Interestingly, some of the new risk loci contribute to risk of other genetically-correlated eye diseases including myopia and age-related macular degeneration. To our knowledge, this study is the first integrative study to combine genetic data from OAG and its correlated traits to identify new risk variants and genetic pathways, highlighting the future potential of combining genetic data from genetically correlated eye traits for the purpose of gene discovery and mapping. PMID- 29449657 TI - Neural activity induced by visual food stimuli presented out of awareness: a preliminary magnetoencephalography study. AB - Obesity is a major public health problem in modern society. Appetitive behavior has been proposed to be partially driven by unconscious decision-making processes and thus, targeting the unconscious cognitive processes related to eating behavior is essential to develop strategies for overweight individuals and obese patients. Here, we presented food pictures below the threshold of awareness to healthy male volunteers and examined neural activity related to appetitive behavior using magnetoencephalography. We found that, among participants who did not recognize food pictures during the experiment, an index of heart rate variability assessed by electrocardiography (low-frequency component power/high frequency component power ratio, LF/HF) just after picture presentation was increased compared with that just before presentation, and the increase in LF/HF was negatively associated with the score for cognitive restraint of food intake. In addition, increased LF/HF was negatively associated with increased alpha band power in Brodmann area (BA) 47 caused by food pictures presented below the threshold of awareness, and level of cognitive restraint was positively associated with increased alpha band power in BA13. Our findings may provide valuable clues to the development of methods assessing unconscious regulation of appetite and offer avenues for further study of the neural mechanisms related to eating behavior. PMID- 29449658 TI - Subduction of a low-salinity water mass around the Xisha Islands in the South China Sea. AB - Based on three climatologically observed temperature and salinity datasets (i.e., GDEM-V3, SCSPOD14 and WOA13), this paper reports a low-salinity (~34.32) water mass in the subsurface-to-intermediate layer around the Xisha Islands in the South China Sea. This water mass mainly subducts from the surface layer into the intermediate layer, characterized by a relatively low potential vorticity tongue extending from the bottom of mixed layer to the thermocline, and accompanied by a thermocline ventilation in spring (especially in April). The potential dynamics are the joint effects of negative wind stress curl, and an anticyclonic eddy triggered by the inherent topographic effect of the Xisha Islands, reflecting that downward vertical motion dominates the subduction. Despite lacking of the homogenous temperature and density, the low-salinity water mass is to some extent similar to the classic mode water and can be regarded as a deformed mode water in the South China Sea. PMID- 29449659 TI - Using immunotherapy to boost the abscopal effect. AB - More than 60 years ago, the effect whereby radiotherapy at one site may lead to regression of metastatic cancer at distant sites that are not irradiated was described and called the abscopal effect (from 'ab scopus', that is, away from the target). The abscopal effect has been connected to mechanisms involving the immune system. However, the effect is rare because at the time of treatment, established immune-tolerance mechanisms may hamper the development of sufficiently robust abscopal responses. Today, the growing consensus is that combining radiotherapy with immunotherapy provides an opportunity to boost abscopal response rates, extending the use of radiotherapy to treatment of both local and metastatic disease. In this Opinion article, we review evidence for this growing consensus and highlight emerging limitations to boosting the abscopal effect using immunotherapy. This is followed by a perspective on current and potential cross-disciplinary approaches, including the use of smart materials to address these limitations. PMID- 29449661 TI - Ocean science research is key for a sustainable future. AB - Human activity has already affected all parts of the ocean, with pollution increasing and fish-stocks plummeting. The UN's recent announcement of a Decade of Ocean Science provides a glimmer of hope, but scientists will need to work closely with decision-makers and society at large to get the ocean back on track. PMID- 29449660 TI - Gut microbiota injury in allogeneic haematopoietic stem cell transplantation. AB - Allogeneic haematopoietic stem cell transplantation (allo-HSCT) is considered to be the strongest curative immunotherapy for various malignancies (primarily, but not limited to, haematologic malignancies). However, application of allo-HSCT is limited owing to its life-threatening major complications, such as graft-versus host disease (GVHD), relapse and infections. Recent advances in large-scale DNA sequencing technology have facilitated rapid identification of the microorganisms that make up the microbiota and evaluation of their interactions with host immunity in various diseases, including cancer. This has resulted in renewed interest regarding the role of the intestinal flora in patients with haematopoietic malignancies who have received an allo-HSCT and in whether the microbiota affects clinical outcomes, including GVHD, relapse, infections and transplant-related mortality. In this Review, we discuss the potential role of intestinal microbiota in these major complications after allo-HSCT, summarize clinical trials evaluating the microbiota in patients who have received allo-HSCT and discuss how further studies of the microbiota could inform the development of strategies that improve outcomes of allo-HSCT. PMID- 29449662 TI - Assessment of interaction between maternal polycyclic aromatic hydrocarbons exposure and genetic polymorphisms on the risk of congenital heart diseases. AB - The major causes of congenital heart diseases (CHDs) are the interactions of genetic and environmental factors. We conducted a case-control study in 357 mothers of CHDs fetuses and 270 control mothers to investigate the association of maternal PAHs exposure, AHR, CYP1A1, CYP1A2, CYP1B1 and CYP2E polymorphisms, the interaction between PAHs exposure and genetic variants with the risk of CHDs. The higher level PAHs exposure was associated with the risk of CHDs (aOR = 2.029, 95% CI: 1.266, 3.251) or subtypes. The haplotypes of AHR or CYP1A2 were associated with the risk of CHDs: AHR: C-G-A-C: aOR = 0.765; T-A-G-A: aOR = 1.33; CYP1A2: A T:aOR = 1.75; C-C: aOR = 0.706. When exposed to higher level PAHs, the risk of CHDs among the mothers carrying rs2158041 "C/T or T/T" genotype or rs7811989 "G/A or A/A" genotype in AHR was 1.724 (chi2 = 7.209, P = 0.007) or 1.735 (chi2 = 7.364, P = 0.007) times greater than the aOR in the mothers carrying wild genotype. The multiplicative-scale interactions between PAHs exposure and polymorphisms of CYP1A2 rs4646425 (P = 0.03) or CYP2E1 rs915908 (P = 0.0238) on the risk of CHDs were observed. Our study suggests that maternal AHR polymorphisms may modify the association of PAHs exposure with CHDs, CYP1A2 or CYP2E1 polymorphisms significantly interact with PAHs exposure on CHDs. PMID- 29449663 TI - Quantitative Evaluation of Pain during Electrocutaneous Stimulation using a Log Linearized Peripheral Arterial Viscoelastic Model. AB - In clinical practice, subjective pain evaluations, e.g., the visual analogue scale and the numeric rating scale, are generally employed, but these are limited in terms of their ability to detect inaccurate reports, and are unsuitable for use in anesthetized patients or those with dementia. We focused on the peripheral sympathetic nerve activity that responds to pain, and propose a method for evaluating pain sensation, including intensity, sharpness, and dullness, using the arterial stiffness index. In the experiment, electrocardiogram, blood pressure, and photoplethysmograms were obtained, and an arterial viscoelastic model was applied to estimate arterial stiffness. The relationships among the stiffness index, self-reported pain sensation, and electrocutaneous stimuli were examined and modelled. The relationship between the stiffness index and pain sensation could be modelled using a sigmoid function with high determination coefficients, where R2 >= 0.88, p < 0.01 for intensity, R2 >= 0.89, p < 0.01 for sharpness, and R2 >= 0.84, p < 0.01 for dullness when the stimuli could appropriately evoke dull pain. PMID- 29449664 TI - Incidence and clinical characteristics of ciguatera fish poisoning in Guadeloupe (French West Indies) between 2013 and 2016: a retrospective cases-series. AB - This retrospective case study analysed the incidence and symptoms of ciguatera fish poisoning (ciguatera) in Guadeloupe (French West Indies) between 2013 and 2016. Cases attending the emergency departments of the two public hospitals and the reports received by the regional health authority in charge of monitoring (ARS) were compiled. Two hundred and thirty-four cases of poisoning were observed, with a mean annual incidence of 1.47/10,000 (95% CI): 1.29-1.66), i.e 5 times higher than the previously reported incidence (1996-2006). The main species described as being responsible for poisoning were fish from the Carangidae family (n = 47) (jack), followed by fish from the Lutjanidae family (n = 27) (snapper), Serranidae family (n = 15) (grouper), Sphyraenidae family (n = 12) (barracuda), and Mullidae family (n = 12) (goatfish). One case of lionfish ciguatera was observed. 93.9% of patients experienced gastrointestinal symptoms, 76.0% presented neurological signs (mainly paresthesia, dysesthesia and pruritus) and 40.3% presented cardiovascular symptoms (bradycardia and/or hypotension). A high frequency (61.4%) of hypothermia (body temperature <36.5 degrees C) was observed. This study reports for the first time the relatively high frequency of cardiac symptoms and low body temperature. The monitoring of ciguatera poisoning throughout the Caribbean region must be improved, notably after reef disturbance due to Irma and Maria major cyclones. PMID- 29449665 TI - Prediction of vaginal birth after cesarean delivery in Chinese parturients. AB - There is an urgent need in China to better predict vaginal birth after cesarean (VBAC) to face the challenge of the second child policy. We aimed to validate a widely used VBAC prediction model (Grobman's model) and a modified version of this model in a Chinese population. In this retrospective cohort study, 444 women with one cesarean delivery and at least one subsequent attempt for a trial of labor in Nanjing, China were included. The considered potential VBAC predictors included Grobman's background variables and five new variables. Overall, a total of 370 women had VBAC, with a success rate of 83.3%. The new background variables "maternal height" and "estimated fetal weight" were considered as two additional predictors for VBAC. The AUC of Grobman's model was 0.831 (95%CI = 0.775-0.886) while the AUC of our modified model with two new variables added was 0.857 (sensitivity = 72.2%, specificity = 83.8%). However, the difference between the AUC of the two models was not significant (Z = -1.69, P = 0.091). We confirmed that Grobman's model was accepted in the Chinese population. A modified model that is supplemented with maternal height and estimated fetal weight needs to be further studied in the Chinese population. PMID- 29449666 TI - Thinning Effects on Biomass and Carbon Stock for Young Taiwania Plantations. AB - Forests play an important role as carbon sinks by sequestrating carbon through photosynthesis. Thinning treatments have large impacts on carbon storage, in addition to strengthening quality and quantity of plantations. This study analyzed the effects of different thinning treatments on carbon stocks in both individual trees and stands of Taiwania (Taiwania cryptomerioides) plantations. Repeated field measurements and allometric equations were used to calculate total C storage and sequestration rates of live trees. The results of this study showed that the total carbon stock of stands with thinning treatments was less than that of the non-thinned stands. The non-thinned 23-year old stands had an estimated carbon stock of 96.8 Mg C ha-1, which is higher than the carbon stock found in either medium- (84.1 Mg C ha-1) or heavily-thinned (74.7 Mg C ha-1) treatment plots of the same age. If the objective of Taiwania plantations was to store large amounts of carbon in the young growth stage, without regard to the initial rate of storage, a better option is no-thinning. However, the medium thinned forests seem to be more promising for carbon sequestration than the no-thinned forests if a longer period is considered. PMID- 29449667 TI - Identification of G-quadruplex clusters by high-throughput sequencing of whole genome amplified products with a G-quadruplex ligand. AB - G-quadruplex (G4) is a DNA secondary structure that has been found to play regulatory roles in the genome. The identification of G4-forming sequences is important to study the specific structure-function relationships of such regions. In the present study, we developed a method for identification of G4 clusters on genomic DNA by high-throughput sequencing of genomic DNA amplified via whole genome amplification (WGA) in the presence of a G4 ligand. The G4 ligand specifically bound to G4 structures on genomic DNA; thus, DNA polymerase was arrested on the G4 structures stabilised by G4 ligand. We utilised the telomestatin derivative L1H1-7OTD as a G4 ligand and demonstrated that the efficiency of amplification of the G4 cluster regions was lower than that of the non-G4-forming regions. By high-throughput sequencing of the WGA products, 9,651 G4 clusters were identified on human genomic DNA. Among these clusters, 3,766 G4 clusters contained at least one transcriptional start site, suggesting that genes are regulated by G4 clusters rather than by one G4 structure. PMID- 29449668 TI - Rhinovirus 3C protease suppresses apoptosis and triggers caspase-independent cell death. AB - Apoptosis and programmed necrosis (necroptosis) determine cell fate, and antagonize infection. Execution of these complementary death pathways involves the formation of receptor-interacting protein kinase 1 (RIPK1) containing complexes. RIPK1 binds to adaptor proteins, such as TRIF (Toll-IL-1 receptor domain-containing-adaptor-inducing interferon-beta factor), FADD (Fas-associated protein with death domain), NEMO (NF-kappaB regulatory subunit IKKgamma), SQSTM1 (sequestosome 1/p62), or RIPK3 (receptor-interacting protein kinase 3), which are involved in RNA sensing, NF-kappaB signaling, autophagosome formation, apoptosis, and necroptosis. We report that a range of rhinoviruses impair apoptosis and necroptosis in epithelial cells late in infection. Unlike the double-strand (ds) RNA mimetic poly I:C (polyinosinic:polycytidylic acid), the exposure of dsRNA to toll-like receptor 3 (TLR3) in rhinovirus-infected cells did not lead to apoptosis execution. Accordingly, necroptosis and the production of ROS (reactive oxygen species) were not observed late in infection, when RIPK3 was absent. Instead, a virus-induced alternative necrotic cell death pathway proceeded, which led to membrane rupture, indicated by propidium iodide staining. The impairment of dsRNA-induced apoptosis late in infection was controlled by the viral 3C protease (3Cpro), which disrupted RIPK1-TRIF/FADD /SQSTM1 immune-complexes. 3Cpro and 3C precursors were found to coimmuno-precipitate with RIPK1, cleaving the RIPK1 death-domain, and generating N-terminal RIPK1 fragments. The depletion of RIPK1 or chemical inhibition of its kinase at the N-terminus did not interfere with virus progeny formation or cell fate. The data show that rhinoviruses suppress apoptosis and necroptosis, and release progeny by an alternative cell death pathway, which is controlled by viral proteases modifying innate immune complexes. PMID- 29449669 TI - Predictive Biomarkers of Gastroesophageal Reflux Disease and Barrett's Esophagus in World Trade Center Exposed Firefighters: a 15 Year Longitudinal Study. AB - Gastroesophageal reflux disease (GERD) and Barrett's Esophagus (BE), which are prevalent in the World Trade Center (WTC) exposed and general populations, negatively impact quality of life and cost of healthcare. GERD, a risk factor of BE, is linked to obstructive airways disease (OAD). We aim to identify serum biomarkers of GERD/BE, and assess the respiratory and clinical phenotype of a longitudinal cohort of never-smoking, male, WTC-exposed rescue workers presenting with pulmonary symptoms. Biomarkers collected soon after WTC-exposure were evaluated in optimized predictive models of GERD/BE. In the WTC-exposed cohort, the prevalence of BE is at least 6 times higher than in the general population. GERD/BE cases had similar lung function, D LCO , bronchodilator response and long acting beta-agonist use compared to controls. In confounder-adjusted regression models, TNF-alpha >= 6 pg/mL predicted both GERD and BE. GERD was also predicted by C-peptide >= 360 pg/mL, while BE was predicted by fractalkine >= 250 pg/mL and IP-10 >= 290 pg/mL. Finally, participants with GERD had significantly increased use of short-acting beta-agonist compared to controls. Overall, biomarkers sampled prior to GERD/BE presentation showed strong predictive abilities of disease development. This study frames future investigations to further our understanding of aerodigestive pathology due to particulate matter exposure. PMID- 29449670 TI - Social inhibition and behavioural flexibility when the context changes: a comparison across six primate species. AB - The ability to inhibit previously employed strategies and flexibly adjust behavioural responses to external conditions may be critical for individual survival. However, it is unclear which factors predict their distribution across species. Here, we investigated social inhibition and behavioural flexibility in six primate species (chimpanzees, bonobos, orangutans, gorillas, capuchin monkeys and spider monkeys) differing in terms of phylogenetic relatedness, foraging ecology and social organization. Depending on the social context, individuals could maximize their food intake by inhibiting the selection of a larger food reward in one condition (i.e. inhibition), but not in others, which required them to flexibly switching strategies across conditions (i.e. behavioural flexibility). Overall, our study revealed inter-specific differences in social inhibition and behavioural flexibility, which partially reflected differences in fission-fusion dynamics. In particular, orangutans and chimpanzees showed the highest level of inhibitory skills, while gorillas and capuchin monkeys showed the lowest one. In terms of behavioural flexibility, orangutans and spider monkeys were the best performers, while bonobos and capuchin monkeys were the worst ones. These results contribute to our understanding that inhibition and behavioural flexibility may be linked in more complex ways than usually thought, although both abilities play a crucial role in efficient problem solving. PMID- 29449671 TI - Identification of juvenility-associated genes in the mouse hepatocytes and cardiomyocytes. AB - Young individuals possess distinct properties that adults do not. The juvenile animals show higher activities for growth, healing, learning and plasticity than adults. The machinery for establishing these juvenile properties is not fully understood. To better understand the molecular constituents for the above properties, we performed a comprehensive transcriptome analysis of differently aged cells of mice by high-throughput sequencing and identified the genes selectively highly expressed in the young cells. These genes, collectively called as juvenility-associated genes (JAGs), show significant enrichments in the functions such as alternative splicing, phosphorylation and extracellular matrix (ECM). This implies the juvenescence might be achieved by these functions at the cell level. The JAG mutations are associated with progeria syndromes and growth disorders. Thus, the JAGs might organize the juvenile property of young animals and analysis of JAGs may provide scientific and therapeutic approaches toward treating the genetic diseases. PMID- 29449672 TI - Electromagnetically induced polarization grating. AB - Based on electromagnetically induced transparency (EIT), we investigate an all optical grating structure to realize polarization-dependent multiple beam splitting in the Raman-Nath limit. To optimize the grating performance, higher excited state [e.g., nS1/2 (n >= 6)] of ultracold 87Rb atoms is employed to construct a five-level Xi-Lambda system sharing one common populated ground state. A principal advantage of our proposed scheme is that the sigma+/- components of a linearly polarized weak probe field can be decoupled and thus be independently diffracted with high efficiency in both one and two dimensions by exploiting different quasi-standing waves as the two strong coupling fields in the Xi and Lambda configurations. Such an all-optical polarization-sensitive operation could greatly enhance the tunability and capacity of all-optical multiplexing, interconnecting, and networking in free space for both classical and quantum applications.

PMID- 29449673 TI - The predictive and prognostic potential of plasma telomerase reverse transcriptase (TERT) RNA in rectal cancer patients. AB - BACKGROUND: Preoperative chemoradiotherapy (CRT) followed by surgery is the standard care for locally advanced rectal cancer, but tumour response to CRT and disease outcome are variable. The current study aimed to investigate the effectiveness of plasma telomerase reverse transcriptase (TERT) levels in predicting tumour response and clinical outcome. METHODS: 176 rectal cancer patients were included. Plasma samples were collected at baseline (before CRT=T0), 2 weeks after CRT was initiated (T1), post-CRT and before surgery (T2), and 4-8 months after surgery (T3) time points. Plasma TERT mRNA levels and total cell-free RNA were determined using real-time PCR. RESULTS: Plasma levels of TERT were significantly lower at T2 (P<0.0001) in responders than in non-responders. Post-CRT TERT levels and the differences between pre- and post-CRT TERT levels independently predicted tumour response, and the prediction model had an area under curve of 0.80 (95% confidence interval (CI) 0.73-0.87). Multiple analysis demonstrated that patients with detectable TERT levels at T2 and T3 time points had a risk of disease progression 2.13 (95% CI 1.10-4.11)-fold and 4.55 (95% CI 1.48-13.95)-fold higher, respectively, than those with undetectable plasma TERT levels. CONCLUSIONS: Plasma TERT levels are independent markers of tumour response and are prognostic of disease progression in rectal cancer patients who undergo neoadjuvant therapy.

AB - Although approximately 100 deubiquitinating enzymes (DUBs) are encoded in the human genome, very little is known about the DUBs that function in mitosis. Here, we demonstrate that DUB USP35 functions as a mitotic regulator by controlling the protein levels and downstream signaling of Aurora B and the depletion of USP35 eventually leads to several mitotic defects including cytokinesis failures. USP35 binds to and deubiquitinates Aurora B, and inhibits the APCCDH1-mediated proteasomal degradation of Aurora B, thus maintaining its steady-state levels during mitosis. In addition, the loss of USP35 decreases the phosphorylation of histone H3-Ser10, an Aurora B substrate. Finally, the transcription factor FoxM1 promotes the expression of USP35, as well as that of Aurora B, during the cell cycle. Our findings suggest that USP35 regulates the stability and function of Aurora B by blocking APCCDH1-induced proteasomal degradation, thereby controlling mitotic progression.

AB - The cerebellum plays a key role in motor tasks, but its involvement in cognition is still being considered. Although there is an association of different psychiatric and cognitive disorders with cerebellar impairments, the lack of time course studies has hindered the understanding of the involvement of cerebellum in cognitive and non-motor functions. Such association was here studied using the Purkinje Cell Degeneration mutant mouse, a model of selective and progressive cerebellar degeneration that lacks the cytosolic carboxypeptidase 1 (CCP1). The effects of the absence of this enzyme on the cerebellum of mutant mice were analyzed both in vitro and in vivo. These analyses were carried out longitudinally (throughout both the pre-neurodegenerative and neurodegenerative stages) and different motor and non-motor tests were performed. We demonstrate that the lack of CCP1 affects microtubule dynamics and flexibility, defects that contribute to the morphological alterations of the Purkinje cells (PCs), and to progressive cerebellar breakdown. Moreover, this degeneration led not only to motor defects but also to gradual cognitive impairments, directly related to the progression of cellular damage. Our findings confirm the cerebellar implication in non-motor tasks, where the formation of the healthy, typical PCs structure is necessary for normal cognitive and affective behavior.

AB - The telomerase reverse transcriptase (TERT) gene is highly expressed in stem cells and silenced upon differentiation. Cancer cells can attain immortality by activating TERT to maintain telomere length and telomerase activity, which is a crucial step of tumorigenesis. Two somatic mutations in the TERT promoter (C228T; C250T) have been identified as gain-of-function mutations that promote transcriptional activation of TERT in multiple cancers, such as melanoma and glioblastoma. A recent study investigating TERT promoter mutations in ovarian carcinomas found C228T and C250T mutations in 15.9% of clear cell carcinomas. However, it is unknown whether these mutations are frequent in other ovarian cancer subtypes, in particular, sex cord-stromal tumors including adult granulosa cell tumors. We performed whole-genome sequencing on ten adult granulosa cell tumors with matched normal blood and identified a TERT C228T promoter mutation in 50% of tumors. We found that adult granulosa cell tumors with mutated TERT promoter have increased expression of TERT mRNA and exhibited significantly longer telomeres compared to those with wild-type TERT promoter. Extension cohort analysis using allelic discrimination revealed the TERT C228T mutation in 51 of 229 primary adult granulosa cell tumors (22%), 24 of 58 recurrent adult granulosa cell tumors (41%), and 1 of 22 other sex cord-stromal tumors (5%). There was a significant difference in overall survival between patients with TERT C228T promoter mutation in the primary tumors and those without it (p = 0.00253, log rank test). In seven adult granulosa cell tumors, we found the TERT C228T mutation present in recurrent tumors and absent in the corresponding primary tumor. Our data suggest that TERT C228T promoter mutations may have an important role in progression of adult granulosa cell tumors. PMID- 29449680 TI - PD-L1 expression in inflammatory myofibroblastic tumors. AB - Inflammatory myofibroblastic tumor is a rare mesenchymal tumor occurring at many anatomic sites, with a predilection for children and young adults. Often indolent, they can be locally aggressive and can metastasize, resulting in significant morbidity and mortality. Therapeutic options are often limited. The identification of underlying kinase mutations has allowed the use of targeted therapy in a subset of patients. Unfortunately, not all tumors harbor mutations and resistance to tyrosine kinase inhibitor therapy is a potential problem. We hypothesized that these tumors may be amenable to PD-L1 therapy given the immune nature of the tumor. PD-L1 expression in inflammatory myofibroblastic tumors has not yet been defined. The purpose of this study was to explore PD-L1 expression in inflammatory myofibroblastic tumors, as adaptive PD-L1 expression is known to enrich for response to anti-PD-1/PD-L1 therapies. Expression of PD-L1 (clone SP142) was assessed in 35 specimens from 28 patients. Positivity was defined as membranous expression in >=5% of cells and evaluated separately in tumor and immune cells. Adaptive vs. constitutive patterns of tumor cell PD-L1 expression were assessed. PD-L1 status was correlated with clinicopathologic features. CD8+ T cell infiltrates were quantified by digital image analysis. ALK status was assessed by immunohistochemistry and/or FISH. Twenty-four (69%) tumors had PD L1(+) tumor cells and 28 (80%) showed PD-L1(+) immune cells. Most recurrent and metastatic tumors (80%) and ALK(-) tumors (88%) were PD-L1(+). Adaptive PD-L1 expression was present in 23 (96%) of PD-L1(+) tumors, which also showed a three four fold increase in CD8+ T cell infiltration relative to PD-L1(-) tumors. Constitutive PD-L1 expression was associated with larger tumor size (p = 0.002). Inflammatory myofibroblastic tumors show frequent constitutive and adaptive PD-L1 expression, the latter of which is thought to be predictive of response to anti PD-1. These data support further investigation into PD-1/PD-L1 blockade in this tumor type. PMID- 29449681 TI - Secondary Philadelphia chromosome acquired during therapy of acute leukemia and myelodysplastic syndrome. AB - The Philadelphia chromosome resulting from t(9;22)(q34;q11.2) or its variants is a defining event in chronic myeloid leukemia. It is also observed in several types of de novo acute leukemia, commonly in B lymphoblastic leukemia, and rarely in acute myeloid leukemia, acute leukemia of ambiguous lineage, and T lymphoblastic leukemia. Acquisition of the Philadelphia chromosome during therapy of acute leukemia and myelodysplastic syndrome is rare. We reported 19 patients, including 11 men and 8 women with a median age of 53 years at initial diagnosis. The diagnoses at initial presentation were acute myeloid leukemia (n = 11), myelodysplastic syndrome (n = 5), B lymphoblastic leukemia (n = 2), and T lymphoblastic leukemia (n = 1); no cases carried the Philadelphia chromosome. The Philadelphia chromosome was detected subsequently at relapse, or at refractory stage of acute leukemia or myelodysplastic syndrome. Of 14 patients evaluated for the BCR-ABL1 transcript subtype, 12 had the e1a2 transcript. In 11 of 14 patients, the diseases before and after emergence of the Philadelphia chromosome were clonally related by karyotype or shared gene mutations. Of 15 patients with treatment information available, 7 received chemotherapy alone, 5 received chemotherapy plus tyrosine kinase inhibitors, 2 received tyrosine kinase inhibitors only, and 1 patient was not treated. Twelve patients had follow-up after acquisition of the Philadelphia chromosome; all had persistent/refractory acute leukemia. Thirteen of 15 patients died a median of 3 months after the emergence of the Philadelphia chromosome. In summary, secondary Philadelphia chromosome acquired during therapy is rare, and is associated with the e1a2 transcript subtype, terminal disease stage, and poor outcome. PMID- 29449682 TI - Anatomic and terminological description and processing of breast pathologic specimens from oncoplastic large volume displacement surgeries. AB - Oncoplastic surgery provides breast cancer patients with greater aesthetic satisfaction without compromising disease-free survival or overall survival rate. Large volume displacement oncoplastic surgical techniques have become increasingly popular as a strategy for improving aesthetic outcomes and extending the option of breast conservation therapy. They often involve breast reduction or mastopexy reconstructive techniques to facilitate resection of large breast volumes on the side of the breast cancer and accompanied with symmetry contralateral breast reductions or mastopexies. However, dissection of large volume displacement oncoplastic surgical specimens presents unique challenges. Compared with traditional mastectomy specimens, they are relatively complicated, which requires the pathologist to understand the surgical procedure and the anatomy of the specimens. Given this, we introduce the standard anatomical and terminological description for the breast pathologic specimens of five large volume displacement oncoplastic surgical techniques commonly performed in our institution for breast cancer management. The individual surgical specimen is composed of one or several components, which include lateral wall, superior keyhole, medial wall, lateral wing, inferior pole, and medial wing. We also present specimen documentation and sectioning procedures used in our institution. The advantages for the patient provided by large volume reduction oncoplastic surgery must be supported by proper evaluation of the surgical pathology specimen. Therefore, we recommend that each section taken from the oncoplastic specimen be labeled as to its specific location in the specimen components. Standardized nomenclature and technique will assist pathologists in accurately evaluating the surgical margins. PMID- 29449683 TI - Adult T-cell leukemia/lymphoma can be indistinguishable from other more common T cell lymphomas. The University of Miami experience with a large cohort of cases. AB - Adult T-cell leukemia/lymphoma, an aggressive T-cell neoplasm, is causally linked to human T-cell lymphotropic virus type 1 and based on this association has a distinct geographic distribution. In our United States-based practice, whose population is enriched for immigrants from human T-cell lymphotropic virus type 1 endemic areas, we have identified that a subset of adult T-cell leukemia/lymphoma, in the absence of human T-cell lymphotropic virus type 1 identification, are indistinguishable from other more common T-cell neoplasms. We retrospectively gathered serology results for anti-human T-cell lymphotropic virus type 1/2 antibody in patients diagnosed with T-cell neoplasms at our institution. A total of 220 human T-cell lymphotropic virus type 1/2 positive patients with T-cell neoplasms were identified; 199 (91%) were correctly classified as adult T-cell leukemia/lymphoma or provisionally as peripheral T cell lymphoma (serology testing pending). Twenty-one cases (9%) were initially misclassified, including the following: 13 presenting with skin +/- peripheral blood involvement and misclassified as mycosis fungoides/Sezary syndrome; 7 with lymphomatous disease, absence of leukemic involvement, and diffuse CD30 expression, misclassified as ALK- negative anaplastic large-cell lymphoma; 1 thought to represent T-prolymphocytic leukemia with TCL-1 gene rearrangement and diffuse marrow involvement. We also present an example of adult T-cell leukemia/lymphoma, which mimicked lymphoepithelioid variant of peripheral T-cell lymphoma also with diffuse marrow involvement. A subset of adult T-cell leukemia/lymphoma can closely mimic a variety of other more common T-cell neoplasms. Due to its extreme clinicopathologic heterogeneity, identification of adult T-cell leukemia/lymphoma requires a high level of suspicion based on patient demographic alone, which should prompt anti-human T-cell lymphotropic virus type 1/2 serology testing in all T-cell neoplasms developing in patients of appropriate demographic. Absence of high level of suspicion, adult T-cell leukemia/lymphoma is easily misclassified. PMID- 29449684 TI - Fibroepithelial lesions of the breast: a comprehensive morphological and outcome analysis of a large series. AB - Mammary fibroepithelial lesions encompass a wide spectrum of tumors ranging from an indolent fibroadenoma to potentially fatal malignant phyllodes tumor. The criteria used for their classification based on morphological assessment are often challenging to apply and there is no consensus as to what constitutes an adequate resection margin. We studied a retrospective cohort of 213 fibroepithelial lesions in 178 patients (80 fibroadenomas with unusual features and 133 phyllodes tumors: 63 benign, 41 borderline, and 29 malignant) in order to describe the spectrum of changes within each group, with special emphasis on margin evaluation. Outcome data were available for 153 fibroepithelial lesions in 139 patients (median 56 months, range 3-249 months). Positive final margin (tumor transected), age < 50 years and a predominantly myxoid stroma were statistically significant predictors of local recurrence, while age > 50, stromal overgrowth, diffuse marked atypia, necrosis and mitotic index of >= 10 per 10 HPF were predictive of distant metastases. Tumors with satellite/bulging nodules were at a significantly higher risk to have a final positive resection margin. Our findings highlight important aspects of the interpretation and reporting of fibroepithelial lesions: the amount of myxoid stroma and the presence of satellite nodules are clinically relevant and should be routinely assessed and reported; infiltrative border might not be a prerequisite for the diagnosis of malignant phyllodes tumor, while the presence of tumor necrosis, massive stromal overgrowth or mitotic index of >= 25 per 10 HPF is diagnostic of malignant phyllodes tumor. On the other hand, increased mitotic index outside of the range of the World Health Organization guidelines in the absence of other worrisome features should be treated with caution, as it can be found in benign tumors. PMID- 29449685 TI - Cross-cultural adaptation and validation of the "Spinal Cord Injury-Falls Concern Scale" in the Italian population. AB - STUDY DESIGN: Psychometrics study. OBJECTIVE: The objective of this study was to develop an Italian version of the Spinal Cord Injury-Falls Concern Scale (SCI FCS) and examine its reliability and validity. SETTING: Multicenter study in spinal units in Northern and Southern Italy. The scale also was administered to non-hospitalized outpatient clinic patients. METHODS: The original scale was translated from English to Italian using the "Translation and Cultural Adaptation of Patient-Reported Outcomes Measures" guidelines. The reliability and validity of the culturally adapted scale were assessed following the "Consensus-Based Standards for the Selection of Health Status Measurement Instruments" checklist. The SCI-FCS-I internal consistency, inter-rater, and intra-rater reliability were examined using Cronbach's alpha coefficient and the intraclass correlation coefficient, respectively. Concurrent validity was evaluated using Pearson's correlation coefficient with the Italian version of the short form of the Wheelchair Use Confidence Scale for Manual Wheelchair Users (WheelCon-M-I-short form). RESULTS: The Italian version of the SCI-FCS-I was administered to 124 participants from 1 June to 30 September 2017. The mean +/- SD of the SCI-FCS-I score was 16.73 +/- 5.88. All SCI-FCS items were either identical or similar in meaning to the original version's items. Cronbach's alpha was 0.827 (p < 0.01), the inter-rater reliability was 0.972 (p < 0.01), and the intra-rater reliability was 0.973 (p < 0.01). Pearson's correlation coefficient of the SCI-FCS-I scores with the WheelCon-M-I-short form was 0.56 (p < 0.01). CONCLUSIONS: The SCI-FCS-I was found to be reliable and a valid outcome measure for assessing manual wheelchair concerns about falling in the Italian population. PMID- 29449686 TI - Impact of genetically engineered maize on agronomic, environmental and toxicological traits: a meta-analysis of 21 years of field data. AB - Despite the extensive cultivation of genetically engineered (GE) maize and considerable number of scientific reports on its agro-environmental impact, the risks and benefits of GE maize are still being debated and concerns about safety remain. This meta-analysis aimed at increasing knowledge on agronomic, environmental and toxicological traits of GE maize by analyzing the peer-reviewed literature (from 1996 to 2016) on yield, grain quality, non-target organisms (NTOs), target organisms (TOs) and soil biomass decomposition. Results provided strong evidence that GE maize performed better than its near isogenic line: grain yield was 5.6 to 24.5% higher with lower concentrations of mycotoxins (-28.8%), fumonisin (-30.6%) and thricotecens (-36.5%). The NTOs analyzed were not affected by GE maize, except for Braconidae, represented by a parasitoid of European corn borer, the target of Lepidoptera active Bt maize. Biogeochemical cycle parameters such as lignin content in stalks and leaves did not vary, whereas biomass decomposition was higher in GE maize. The results support the cultivation of GE maize, mainly due to enhanced grain quality and reduction of human exposure to mycotoxins. Furthermore, the reduction of the parasitoid of the target and the lack of consistent effects on other NTOs are confirmed.

AB - Pancreatic neuroendocrine tumours (PNETs) might occur as a non-familial isolated endocrinopathy or as part of a complex hereditary syndrome, such as multiple endocrine neoplasia type 1 (MEN1). MEN1 is an autosomal dominant disorder characterized by the combined occurrence of PNETs with tumours of the parathyroids and anterior pituitary. Treatments for primary PNETs include surgery. Treatments for non-resectable PNETs and metastases include biotherapy (for example, somatostatin analogues, inhibitors of receptors and monoclonal antibodies), chemotherapy and radiological therapy. All these treatments are effective for PNETs in patients without MEN1; however, there is a scarcity of clinical trials reporting the efficacy of the same treatments of PNETs in patients with MEN1. Treatment of PNETs in patients with MEN1 is challenging owing to the concomitant development of other tumours, which might have metastasized. In recent years, preclinical studies have identified potential new therapeutic targets for treating MEN1-associated neuroendocrine tumours (including PNETs), and these include epigenetic modification, the beta-catenin-wingless (WNT) pathway, Hedgehog signalling, somatostatin receptors and MEN1 gene replacement therapy. This Review discusses these advances. PMID- 29449691 TI - Enhanced release of acid sphingomyelinase-enriched exosomes generates a lipidomics signature in CSF of Multiple Sclerosis patients. AB - Multiple Sclerosis (MuS) is a complex multifactorial neuropathology, resulting in heterogeneous clinical presentation. A very active MuS research field concerns the discovery of biomarkers helpful to make an early and definite diagnosis. The sphingomyelin pathway has emerged as a molecular mechanism involved in MuS, since high levels of ceramides in cerebrospinal fluid (CSF) were related to axonal damage and neuronal dysfunction. Ceramides are the hydrolysis products of sphingomyelins through a reaction catalyzed by a family of enzymes named sphingomyelinases, which were recently related to myelin repair in MuS. Here, using a lipidomic approach, we observed low levels of several sphingomyelins in CSF of MuS patients compared to other inflammatory and non-inflammatory, central or peripheral neurological diseases. Starting by this result, we investigated the sphingomyelinase activity in CSF, showing a significantly higher enzyme activity in MuS. In support of these results we found high number of total exosomes in CSF of MuS patients and a high number of acid sphingomyelinase-enriched exosomes correlated to enzymatic activity and to disease severity. These data are of diagnostic relevance and show, for the first time, high number of acid sphingomyelinase-enriched exosomes in MuS, opening a new window for therapeutic approaches/targets in the treatment of MuS. PMID- 29449692 TI - The deubiquitinase USP9X promotes tumor cell survival and confers chemoresistance through YAP1 stabilization. AB - The Yes-associated protein 1 (YAP1), a major downstream effector of the Hippo pathway, functions as a transcriptional regulator and has an important role in cellular control of organ size and tumor growth. Elevated oncogenic activity of YAP1 has been clarified in different types of human cancers, which contributes to cancer cell survival and chemoresistance. However, the molecular mechanism of YAP1 overexpression in cancer is still not clear. Here we demonstrate that the deubiquitination enzyme USP9X deubiquitinates and stabilizes YAP1, thereby promoting cancer cell survival. Increased USP9X expression correlates with increased YAP1 protein in human breast cancer cell lines and patient samples. Moreover, depletion of USP9X increases YAP1 polyubiquitination, which in turn elevates YAP1 turnover and cell sensitivity to chemotherapy. Overall, our study establishes the USP9X-YAP1 axis as an important regulatory mechanism of breast cancer and provides a rationale for potential therapeutic interventions in the treatment of breast cancer. PMID- 29449693 TI - Tumor cell-intrinsic Tim-3 promotes liver cancer via NF-kappaB/IL-6/STAT3 axis. AB - T-cell immunoglobulin and mucin-domain containing-3 (Tim-3), mediating immune exhaustion in tumor microenvironment, has become a promising target for tumor therapy. However, the exact mechanisms for tumor cell-intrinsic Tim-3 in tumor development and its potential contribution in Tim-3-targeted therapy strategy have not been elucidated yet. In this study, we showed that human liver cancer tissues contained high ratio of Tim-3-expressing hepatocytes, and cytokines rich in tumor microenvironment and HBV involved in Tim-3 upregulation in malignant hepatocytes. We demonstrated that hepatocyte-specific Tim-3 overexpression enhances tumor cell growth, whereas Tim-3 inhibition on malignant hepatocytes by anti-Tim-3 antibodies or RNAi suppresses tumor growth both in vitro and in Tim-3 knockout mice. Mechanistically, the hepatocyte-Tim-3 receptor activates NF-kappaB phosphorylation, which in turn stimulates IL-6 secretion and STAT3 phosphorylation. Our results identify tumor cell-intrinsic functions of Tim-3 in tumorigenesis and suggest that blocking Tim-3 in tumor cells might contribute to the clinical efficacy of anti-Tim-3 antibody treatment in the future tumor therapy. PMID- 29449694 TI - Interaction between STAT3 and GLI1/tGLI1 oncogenic transcription factors promotes the aggressiveness of triple-negative breast cancers and HER2-enriched breast cancer. AB - Signal transducer and activator of transcription 3 (STAT3), glioma oncogene homolog 1 (GLI1), and truncated GLI1 (tGLI1) are oncogenic transcription factors playing important roles in breast cancer. tGLI1 is a gain-of-function GLI1 isoform. Whether STAT3 physically and/or functionally interacts with GLI1/tGLI1 has not been explored. To address this knowledge gap, we analyzed 47 node positive breast cancer specimens using immunohistochemical staining and found that phosphorylated-STAT3 (Y705), GLI1, and tGLI1 are co-overexpressed in the majority of triple-negative breast carcinomas (64%) and HER2-enriched (68%) breast carcinomas, and in lymph node metastases (65%). Using gene set enrichment analysis, we analyzed 710 breast tumors and found that STAT3 activation and GLI1/tGLI1 activation signatures are co-enriched in triple-negative subtypes of breast cancers and HER2-enriched subtypes of breast cancers, but not in luminal subtypes of breast cancers. Patients with high levels of STAT3 and GLI1/tGLI1 co activation in their breast tumors had worse metastasis-free survival compared to those with low levels. Since these proteins co-overexpress in breast tumors, we examined whether they form complexes and observed that STAT3 interacted with both GLI1 and tGLI1. We further found that the STAT3-GLI1 and STAT3-tGLI1 complexes bind to both consensus GLI1-binding and STAT3-binding sites using chromatin immunoprecipitation (ChIP) assay, and that the co-overexpression markedly activated a promoter controlled by GLI1-binding sites. To identify genes that can be directly co-activated by STAT3 and GLI1/tGLI1, we analyzed three ChIP-seq datasets and identified 34 potential target genes. Following validations using reverse transcription polymerase chain reaction and survival analysis, we identified three genes as novel transcriptional targets of STAT3 and GLI1/tGLI1, R-Ras2, Cep70, and UPF3A. Finally, we observed that co-overexpression of STAT3 with GLI1/tGLI1 promoted the ability of breast cancer cells to form mammospheres and that STAT3 only cooperates with tGLI1 in immortalized mammary epithelial cells. In summary, our study identified novel physical and functional cooperation between two families of oncogenic transcription factors, and the interaction contributes to aggressiveness of breast cancer cells and poor prognosis of triple negative breast cancers and HER2-enriched breast cancers. PMID- 29449695 TI - Arresting of miR-186 and releasing of H19 by DDX43 facilitate tumorigenesis and CML progression. AB - Cancer-testis (CT) antigens, rarely in normal tissues except testis, are expressed in many tumor types. In recent years, DDX43 has been shown to be expressed in several malignancies. However, the role of DDX43 during tumorigenesis is not well established. In the present study, we explored the function of DDX43 in chronic myeloid leukemia (CML). We found that DDX43 overexpression in CML cell lines enhanced survival and colony formation, inhibited cell apoptosis, promoted tumorigenesis, and CML progression. In contrast, silencing of DDX43 inhibited cell survival and tumorigenesis. Upregulated H19 and downregulated miR-186 were identified in DDX43-transfected cells. Furthermore, we demonstrated that miR-186 targeted DDX43, and overexpressed miR-186 increased apoptosis and decreased cell survival. We also showed that DDX43 regulated the expression of H19 through demethylation and silencing H19 inhibited cell survival. Taken together, these results indicate that DDX43 provides critical support to the progression of CML by enhancing cell survival, colony formation, and inhibiting cell apoptosis, thereby implicating DDX43 as a potential therapeutic target in CML.

PMID- 29449697 TI - Stereochemical identification of glucans by oligothiophenes enables cellulose anatomical mapping in plant tissues. AB - Efficient use of plant-derived materials requires enabling technologies for non disruptive composition analysis. The ability to identify and spatially locate polysaccharides in native plant tissues is difficult but essential. Here, we develop an optical method for cellulose identification using the structure responsive, heptameric oligothiophene h-FTAA as molecular fluorophore. Spectrophotometric analysis of h-FTAA interacting with closely related glucans revealed an exceptional specificity for beta-linked glucans. This optical, non disruptive method for stereochemical differentiation of glycosidic linkages was next used for in situ composition analysis in plants. Multi-laser/multi-detector analysis developed herein revealed spatial localization of cellulose and structural cell wall features such as plasmodesmata and perforated sieve plates of the phloem. Simultaneous imaging of intrinsically fluorescent components revealed the spatial relationship between cell walls and other organelles, such as chloroplasts and lignified annular thickenings of the trachea, with precision at the sub-cellular scale. Our non-destructive method for cellulose identification lays the foundation for the emergence of anatomical maps of the chemical constituents in plant tissues. This rapid and versatile method will likely benefit the plant science research fields and may serve the biorefinery industry as reporter for feedstock optimization as well as in-line monitoring of cellulose reactions during standard operations. PMID- 29449696 TI - Snail regulates BMP and TGFbeta pathways to control the differentiation status of glioma-initiating cells. AB - Glioblastoma multiforme is a brain malignancy characterized by high heterogeneity, invasiveness, and resistance to current therapies, attributes related to the occurrence of glioma stem cells (GSCs). Transforming growth factor beta (TGFbeta) promotes self-renewal and bone morphogenetic protein (BMP) induces differentiation of GSCs. BMP7 induces the transcription factor Snail to promote astrocytic differentiation in GSCs and suppress tumor growth in vivo. We demonstrate that Snail represses stemness in GSCs. Snail interacts with SMAD signaling mediators, generates a positive feedback loop of BMP signaling and transcriptionally represses the TGFB1 gene, decreasing TGFbeta1 signaling activity. Exogenous TGFbeta1 counteracts Snail function in vitro, and in vivo promotes proliferation and re-expression of Nestin, confirming the importance of TGFB1 gene repression by Snail. In conclusion, novel insight highlights mechanisms whereby Snail differentially regulates the activity of the opposing BMP and TGFbeta pathways, thus promoting an astrocytic fate switch and repressing stemness in GSCs.

In the case of Alzheimer disease (AD), extracellular amyloid-beta (Abeta) aggregates and intracellular tau neurofibrillary tangles are the two neuropathological hallmarks of the disease. Abeta-PET imaging has already been approved for clinical use and is being used in clinical trials of anti-Abeta therapies both for patient recruitment and as an outcome measure. These studies have shown that Abeta accumulation is a protracted process that can extend for more than 2 decades before the onset of clinical AD. This Review describes how in vivo brain imaging of Abeta pathology has revolutionized the evaluation of patients with clinical AD by providing robust and reproducible statements of global or regional brain Abeta burden and enabling the monitoring of disease progression. The role of selective tau imaging is discussed, focusing on how longitudinal tau and Abeta imaging studies might reveal the various effects (sequential and/or parallel, independent and/or synergistic) of these proteins on progression, cognition and other disease-specific biomarkers of neurodegeneration. Finally, imaging studies are discussed in the context of elucidating the respective roles of Abeta and tau in AD and in advancing our understanding of the relationship and/or interplay between these two proteinopathies. PMID- 29449705 TI - Comparison between L-type and N/L-type calcium channel blockers in the regulation of home blood-pressure variability in elderly hypertensive patients. AB - Recent studies suggest that L-type calcium channel blockers (CCBs) contribute to reducing blood pressure (BP) variability. We investigated whether inhibition of the N-type calcium channel has an additional effect on BP variability by comparing the effect of L-type and L/N-type CCBs on home BP variability in elderly hypertensive patients. Twenty-six hypertensive patients (>=65 years) were subjected to repeated changes with the administration of amlodipine (L-type CCB) and cilnidipine (L/N-type CCB) every 2 months. They measured the home BP in the morning and evening, and the coefficient of variation (CV) was calculated. We measured the brachial-ankle pulse wave velocity (baPWV) and urinary catecholamine excretion as an index of the arterial stiffness and sympathetic nerve activity, respectively. There was no difference in the effect of both drugs on the CV in the morning and evening, while amlodipine was associated with a modestly higher pulse rate and lower BP than cilnidipine. By comparing individual patient data for the CV with each drug, we found that higher urinary catecholamine excretion was associated with the effectiveness of cilnidipine over amlodipine in the BP variability in the morning, which was not the case in the evening. In contrast, lower baPWV was associated with the effectiveness of amlodipine over cilnidipine on BP variability in the evening. Lower baPWV was also associated with lower BP variability in the evening. Cilnidipine has a similar capacity as amlodipine in reducing home BP variability, but the underlying mechanisms in reducing BP variability may differ.

AB - Endothelial dysfunction is a form of subclinical cardiovascular disease that may be involved in preterm birth and small-for-gestational-age deliveries. However, concentrations of biomarkers of endothelial dysfunction before pregnancy have rarely been measured. We hypothesized that higher levels of biomarkers of endothelial dysfunction (cellular adhesion molecules and selectins) would be associated with odds of preterm birth and/or small-for-gestational-age deliveries. We included 235 women from the Coronary Artery Risk Development in Young Adults (CARDIA) study who were nulliparous at Y7, reported >=1 live birth through Y25, and had >=1 biomarker measured at Y7. We tested for associations between individual biomarkers and an averaged z-score representing total endothelial dysfunction with preterm birth and/or small-for-gestational-age deliveries using Poisson regression, adjusted for demographic and clinical characteristics at the exam immediately preceding index birth. At Y7, total evidence of endothelial dysfunction was similar in women who did (n = 59) and did not have (n = 176) preterm birth and/or small-for-gestational-age deliveries. There was no association between biomarkers of endothelial dysfunction (either individual biomarker or total score) with odds of preterm birth and/or small-for gestational-age deliveries after adjustment: IRR = 1.01, 95% CI: 0.74, 1.39, p = 0.93 for total endothelial biomarker score. Associations were not modified by race. We conclude that biomarkers of endothelial dysfunction in nulliparous women, measured ~3 years before pregnancy, did not identify women at risk for preterm birth and/or small-for-gestational-age deliveries. This suggests that the maternal endothelial dysfunction that is believed to contribute to these birth outcomes may not be detectable before pregnancy. PMID- 29449707 TI - Modulation of cardiac stem cell characteristics by metoprolol in hypertensive heart disease. AB - Cardiac stem cells (CSCs) play a vital role in cardiac remodeling. Uncontrolled hypertension leads to cardiac hypertrophy, followed by cardiac failure. Pathological remodeling is associated with enhanced oxidative stress. Decreased cardiac stem cell efficiency is speculated in heart diseases. Maintaining a healthy stem cell population is essential for preventing progressive cardiac remodeling. Some anti-hypertensive drugs are cardioprotective. However, the effect of these drugs on CSCs has not been investigated. Metoprolol is a cardioprotective anti-hypertensive agent. To examine whether metoprolol can prevent the deterioration of CSC efficiency, spontaneously hypertensive rats (SHRs) were treated with this drug, and the effects on stem cell function were evaluated. Six-month-old male SHRs were treated with metoprolol (50 mg * kg-1per day) for 2 months. The effectiveness of the treatment at reducing blood pressure and reducing hypertrophy was ensured, and the animals were killed. Cardiac stem cells were isolated from the atrial tissue, and the effect of metoprolol on stem cell migration, proliferation, differentiation, and survival was evaluated by comparing the treated SHRs with untreated SHRs and normotensive Wistar rats. Compared to the Wistar rats, the SHR rats presented with a decrease in stem cell migration and proliferation and an increase in intracellular oxidative stress and senescence. Treating SHRs with metoprolol increased CSC migration and proliferation potential and stemness retention. Cellular senescence and oxidative stress were reduced. The attributes of stem cells from the metoprolol-treated SHRs were comparable to those of the Wistar rats. The restoration of stem cell efficiency is expected to prevent hypertension-induced progressive cardiac remodeling. PMID- 29449708 TI - Cancer: Reset your circadian clock.

PMID- 29449713 TI - Control of synaptic plasticity in deep cortical networks. AB - Humans and many other animals have an enormous capacity to learn about sensory stimuli and to master new skills. However, many of the mechanisms that enable us to learn remain to be understood. One of the greatest challenges of systems neuroscience is to explain how synaptic connections change to support maximally adaptive behaviour. Here, we provide an overview of factors that determine the change in the strength of synapses, with a focus on synaptic plasticity in sensory cortices. We review the influence of neuromodulators and feedback connections in synaptic plasticity and suggest a specific framework in which these factors can interact to improve the functioning of the entire network.

AB - In humans, the period from term birth to ~2 years of age is characterized by rapid and dynamic brain development and plays an important role in cognitive development and risk of disorders such as autism and schizophrenia. Recent imaging studies have begun to delineate the growth trajectories of brain structure and function in the first years after birth and their relationship to cognition and risk of neuropsychiatric disorders. This Review discusses the development of grey and white matter and structural and functional networks, as well as genetic and environmental influences on early-childhood brain development. We also discuss initial evidence regarding the usefulness of early imaging biomarkers for predicting cognitive outcomes and risk of neuropsychiatric disorders.

PMID- 29449715 TI - Leptin and brain-adipose crosstalks. AB - Interactions between the brain and distinct adipose depots have a key role in maintaining energy balance, thereby promoting survival in response to metabolic challenges such as cold exposure and starvation. Recently, there has been renewed interest in the specific central neuronal circuits that regulate adipose depots. Here, we review anatomical, genetic and pharmacological studies on the neural regulation of adipose function, including lipolysis, non-shivering thermogenesis, browning and leptin secretion. In particular, we emphasize the role of leptin sensitive neurons and the sympathetic nervous system in modulating the activity of brown, white and beige adipose tissues. We provide an overview of advances in the understanding of the heterogeneity of the brain regulation of adipose tissues and offer a perspective on the challenges and paradoxes that the community is facing regarding the actions of leptin on this system. PMID- 29449719 TI - Incidental inequity. PMID- 29449720 TI - Biallelic inactivating variants in the GTPBP2 gene cause a neurodevelopmental disorder with severe intellectual disability. AB - Congenital neurological disorders are genetically highly heterogeneous. Rare forms of hereditary neurological disorders are still difficult to be adequately diagnosed. Pertinent studies, especially when reporting only single families, need independent confirmation. We present three unrelated families in which whole exome sequencing identified the homozygous non-sense variants c.430[C>T];[C>T] p.(Arg144*), c.1219[C>T];[C>T] p.(Gln407*) and c.1408[C>T];[C>T] p.(Arg470*) in GTPBP2. Their clinical presentations include early onset and apparently non progressive motor and cognitive impairment, and thereby overlap with findings in a recently described family harbouring a homozygous GTPBP2 splice site variant. Notable differences include structural brain abnormalities (e.g., agenesis of the corpus callosum, exclusive to our patients), and evidence for brain iron accumulation (exclusive to the previously described family). This report confirms pathogenicity of biallelic GTPBP2 inactivation and broadens the phenotypic spectrum. It also underlines that a potential involvement of brain iron accumulation needs clarification. Further patients will have to be identified and characterised in order to fully define the core features of GTPBP2-associated neurological disorder, but future approaches to molecular diagnosis of neurodevelopmental disorders should implement GTPBP2. PMID- 29449722 TI - Current usefulness of aspiration cytology (FNAC) in the head and neck diagnosis. AB - Background: Fine Needle Aspiration Cytology (FNAC) is a well established and widely used method for both a preliminary and sometime final non-invasive pathologic diagnosis. FNAC is a simple and inexpensive diagnostic tool and should represent the standard of care in developing and resource-poor countries while maintaining its diagnostic usefulness in developed and advanced ones. Methods: The concordance between preoperative FNAC and final histology was evaluated in 168 patients operated on at the Otorhinolaryngology Unit, "A. Murri" Hospital, Fermo (Italy), from January 2012 to October 2016, including thyroid cases, salivary glands and cervical masses. Results: The percentages of correct diagnosis provided by FNAC were good in all groups of pathologies and in accordance with the mean data of the literature. In particular the kappa statistic for the degree of agreement between FNAC and definitive histology (good > 0.6 and excellent > 0.8) was 0.74 for the thyroid, 0.83 for the parotid and 0.71 for both the submandibular and the cervical masses. Discussion: Thy 3 group is still the most challenging for a successful FNAC diagnostic prediction. Especially in the developed and advanced countries, both the immediate review of the smear with its repetition, if needed, and the aspiration performed under CT/MRI guidance, when necessary, seem to further empower FNAC diagnostic resolution and should be pursued. Being routinely used for more than 40 years, FNAC is still a valuable and cost-effective tool to distinguish between cases that don't need any treatment, cases to be treated medically and those that require surgical excision. In the Authors' opinion every institution should periodically review its data in order to monitor and assess the accuracy of its diagnostic activity. PMID- 29449721 TI - Bi-allelic inactivating variants in the COCH gene cause autosomal recessive prelingual hearing impairment. AB - Pathogenic variant in COCH are a known cause of DFNA9 autosomal dominant progressive hearing loss and vestibular dysfunction with adult onset. Hitherto, only dominant nonsynonymous variants and in-frame deletions with a presumed dominant negative or gain-of-function effect have been described. Here, we describe two brothers with congenital prelingual deafness and a homozygous nonsense c.292C>T(p.Arg98*) COCH variant, suggesting a loss-of-function effect. Vestibular dysfunction starting in the first decade was observed in the older patient. The heterozygous parents and sibling have normal hearing and vestibular function, except for the mother, who shows vestibular hyporeflexia and abnormal smooth pursuit tests, most likely due to concomitant disease. This is the first report of autosomal recessive inheritance of cochlea-vestibular dysfunction caused by a pathogenic variant in the COCH gene. An earlier onset of hearing impairment and vestibular dysfunction compared to the dominant hearing loss causing COCH variants is observed. PMID- 29449723 TI - An outbreak of cutaneous leishmaniasis in Modena province (Northern Italy): report of 35 cases. AB - Canine Leishmaniasis is a disease endemic in many parts of Europe, carried by insects of phlebotomous species. Humans are occasional hosts of the parasites. Cases of human leishmaniasis have been registered in Italy, particularly in the southern and coastal regions. In the period 1997-2016, we collected a series of 35 patients affected by cutaneous leishmaniasis, uncovered by skin biopsy and histological examination, 21 of them found in last 3 years. The patients, 28 males and 7 female, aged between 19 and 91, resided in a restricted area of Northern Italy, and none, but two, had travelled abroad. Lesions presented clinically mostly as single nodule or plaque, often ulcerated, and involved predominantly head-neck and upper extremities. Histology showed a diffuse, granulomatous inflammation including numerous plasma cells. Variable numbers of amastigotes were visible, usually in the superficial part of the dermis, in all cases but two. In these two cases, highly suspicious by clinico-pathologic features, PCR analysis allowed to achieve the correct diagnosis. Our attention was then focused on the geographical residence of the patients, that turned out to be mostly in the piedmont area, whereas only one lived in the alluvial area corresponding to Padana plain. These data underline the diffusion of phlebotomus in northern areas of Italy, and particularly on the hills, characterized by a type of soil more favorable to vector survival; also, they indicate the adaptation of leishmania to hosts other than dogs, such as foxes and small rodents. Histology alone resulted sufficient to make diagnosis in most cases, but PCR analysis is recommended in those cases showing a suspicious background, in absence of amastigotes. PMID- 29449724 TI - Angiomyofibroblastoma of the spermatic cord: a case report. AB - Angiomyofibroblastoma (AMF) is a rare benign mesenchymal tumor with tendency to arise in the lower genital tract of middleaged women, predominately in the vulva. A few cases of AMF in males have been reported involving the scrotum, perineum or spermatic cord. We report a new case of AMF arising in the right inguinal region of a 27-year-old man. The tumor was well-circumscribed, myxoid and measured 30 mm in maximum dimension. On microscopic examination, the tumor was composed of spindle cells without atypia and with less than one mitosis figure per 10 high power fields. Multinucleated cells and mast cells were observed. The stroma was myxoid and edematous with abundant capillary-sized blood vessels. Immunohistochemical staining showed a strong immunoreactivity for desmin and smooth muscle actin. The tumor cells were negative for estrogen receptors and focally positive for progesterone receptors with a low proliferative index of Ki67 (< 5%). This unusual neoplasm should be distinguished from aggressive angiomyxoma and other myxoid malignant tumors. PMID- 29449725 TI - Iatrogenic colorectal Kaposi's sarcoma complicating a refractory ulcerative colitis in a human immunodeficiency negative-virus patient. AB - Kaposi sarcoma is an unusual tumor associated to a human herpes virus-8 infection involving the skin or internal organs. Iatrogenic Kaposi's sarcoma often occurs in patients receiving immunosuppressive therapy. So far, a few Kaposi's sarcoma cases have been reported in the literature associated with inflammatory bowel diseases. We report a 53-year-old male diagnosed with a severe refractory ulcerative colitis who was treated with corticosteroids and azathioprine. The patient underwent a colectomy after the failure of medical treatment. Histological examination of the colon showed findings suggestive of Kaposi's sarcoma. Immunohistochemistry for human herpes virus-8 was positive in the colonic lesions. Correspondence. PMID- 29449726 TI - Primary well differentiated neuroendocrine tumor of ovary collides with Mucinous borderline tumor in a postmenopausal female: a report of case and review of literature. AB - Collision tumors represent a coexistence of two adjacent but histologically distinct tumors without histologic admixture in an organ. Primary well differentiated neuroendocrine tumor of ovary is rare and coexistent borderline mucinous tumor makes this association extremely rare. Although these tumors have been reported in other organs, its occurrence in ovary is rare. Collision tumor comprising primary neuroendocrine tumor of ovary and mucinous borderline tumor is an extremely rare occurrence. Here we report a case of this collision tumor in a postmenopausal female. H&E and immunohistochemical stains for chromogranin, synaptophysin, CDX-2, CK20, CK7 and Ki-67 were performed to confirm the diagnosis of collision tumor. Extensive search of literature revealed only a couple of cases report so far with this association. Our case is unique for a reason that we have reported trabecular variant of neuroendocrine tumor while the previously reported cases were insular variant. Management depends on patient's age, desire for fertility and disease distribution. PMID- 29449727 TI - Adenoid ameloblastoma with dentinoid and cellular atypia: a case report and literature review. AB - Adenomatoid odontogenic tumor (AOT) is always benign. Given the very rare recurrence rate and the zero potential of malignant transformation, authors have considered it a hamartoma. Accordingly, 'AOT' is no more than a misnomer. This report, however, describes the first recognition of cellular atypia and plemorphism in a peripheral orophayrngeal AOT which embraces an ameloblastic component. The overall picture was diagnosed, after careful histological and immunohitochemical assessment, as a peripheral adenoid ameloblastoma. This find may promote a new pathogenetic scenario to the nosology of this debatable lesion. PMID- 29449728 TI - Vaginal rhabdomyoma: a case report of an uncommon and misleading neoplasm. AB - Vaginal rhabdomyoma is an extremely rare tumor which presents as a vaginal polypoid masses. It is essential to differentiate it from benign and malignant mimickers so that appropriate therapy may be provided. The present report describes a vaginal wall nodule of a symptomatic 24-year-old woman. Local excision and subsequent pathological examination were performed. The final diagnosis was vaginal rhabdomyoma. The literature is reviewed and differential diagnosis are discussed. PMID- 29449729 TI - Parotid metastasis of renal cell carcinoma, mimicking primary clear cell oncocytoma: report of a case and brief review of the literature. AB - Malignancies of the parotid gland are relatively uncommon, accounting for only 3 6% of all head and neck cancers. Most of them are primary neoplasms, metastases are uncommon. Renal cell carcinoma (RCC) represents 3% of adult malignancies, the clear cell type comprises up to 70% of all RCC. RCC has an unpredictable behavior and the unique potential to metastasize to nearly every organ in the body. Though not as frequent, metastatic RCC to the head and neck has been identified in the thyroid, salivary glands, skull base, sinuses, pharynx, tonsils, tongue, lip and skin. Metastasis to the parotid gland is very rare. Here, we report the case of a clear cell type RCC metastatic to the parotid gland and mimicking a primary clear cell oncocytoma. Differential diagnoses and a brief review of the literature are added. PMID- 29449730 TI - Ovarian leiomyoma with myxoid stroma. AB - Ovarian smooth muscle tumours are rare. Notable myxoid change in smooth muscle tumours is uncommon, and raises diagnostic issues that need to be considered on evaluating a spindle cell lesion with notable myxoid change. There is only one case of myxoid leiomyoma of the ovary previously reported. We here report a case of ovarian leiomyoma with areas of myxoid stroma and discuss the relevant differential diagnosis and histological features to be assessed in such a lesion. PMID- 29449731 TI - Mixed malignant mullerian tumor with neuroendocrine features in an irradiated uterus for cervical carcinoma. A unique association? A morphological, immunohistochemisty and ultrastructural study. AB - Chemo-radiation represents an effective therapy for carcinoma of the uterine cervix. The endometrium may however receive a consistent dose of mutagenic radiations and patients may have an increased risk of secondary malignancies. Endometrial mixed malignant mullerian tumor (MMMT) is a rare, highly aggressive disease, and neuroendocrine features are even rarer. A 68 years old woman underwent radio-chemotherapy for a squamous cell carcinoma of the cervix. Follow up was uneventful until, eight years after radio-chemotherapy, imaging exams detected a diffuse enlargement of the uterine body. Radical hysterectomy revealed a multiphasic lesion with both sarcomatous and mixed carcinomatous components. The carcinomatous, component presented neuroendocrine histologic and ultrastuctural features and an intense expression of neuroendocrine immunohistochemistry markers. No residual cervical carcinoma was documented (pR0). The patient died of disease after 9 months. Reported cases further demonstrate how the irradiation of the uterus for cervical cancer carries a not negligible risk of developing a second endometrial cancer. The second cancer may develop years after initial therapy and may have aggressive histologic and clinical features. This case underlines the importance for a long follow-up in women having received radio-chemotherapy alone. PMID- 29449732 TI - Gastric metastasis from cervix carcer: a case report. AB - Gastric metastasis by solid tumor cancer is a rare event. Concomitant metastases to other organs are frequent, so that this condition is often associated to a poor prognosis. Upper gastrointestinal bleeding and anemia are the most common presenting symptoms. We present the case of a 81 years old women previously treated for cervix carcinoma showing later a stomach metastasis. The patient is alive and disease free 39 months after salvage gastrectomy. A radical surgery in selected patients could be useful for symptom palliation and prolonged survival. PMID- 29449733 TI - Dedifferentiated primary mediastinal liposarcoma mimicking a thymic tumor. AB - Mediastinal tumors are heterogeneous and the diagnosis depends on their location in the mediastinum. The most frequent tumors are germinal tumor, lymphoma and thymoma. The clinical and radiological aspects are often not sufficient to orient the diagnosis and biopsy is necessary to confirmed it. Here, we present a rare case of an anterior mediastinal mass incidentally detected in a 63 years old man during assessment for asthma. The lesion was presumptively diagnosed as a thymic epithelial tumor based on location and radiological characteristics. Surgical biopsy revealed a primary dedifferentiated mediastinal liposarcoma with multiple lung metastases. PMID- 29449734 TI - Breast granulomatosis with polyangiitis mimicking breast cancer. AB - Inflammatory lesions of the breast encompass primary reactive processes and local manifestation of systemic diseases. They are very rare and they are generally treated without resort to biopsy. Nevertheless they could be clinically challenge mimicking malignant process and needing surgery to reach a correct diagnosis. Here we describe a rare case of breast granulomatosis with polyangiitis, which presented with radiological and clinical alarming features that immediately raised the suspicious of malignancy leading to breast-conserving surgery. PMID- 29449735 TI - ALK-positive adenocarcinoma of the lung expressing neuroendocrine markers and presenting as a "pituitary adenoma". AB - We report an ALK-rearranged adenocarcinoma of the lung presenting as a pituitary metastasis, clinically simulating a pituitary adenoma. The patient, a 50 year old, former-smoking woman was admitted with a Parinaud's syndrome characterized by progressive oculomotor impairment of visual verticality, bitemporal hemianopsia and nystagmus. Imaging studies showed a sellar tumor and the biopsy revealed a TTF-1 and napsin positive lung adenocarcinoma strongly expressing synaptophysin and CD56, also harboring ALK rearrangement. A subsequent CT scan disclosed the primary lung mass of the left upper lobe. The patient progressed after 4 cycles of cisplatin/pemetrexed as first line treatment, but showed a partial response and a significant clinical benefit from the combination of ceritinib and nivolumab in a phase Ib trial. Despite its central nervous system tropism, ALK-rearranged adenocarcinoma manifesting with pituitary gland involvement was never reported. Second generation ALK inhibitors seem the best therapeutic strategy. PMID- 29449736 TI - Adenoid cystic carcinoma: a rare breast carcinoma. AB - Adenoid cystic carcinoma is a rare neoplasm accounting for <0.1% of breast carcinomas. The mean age of presentation is fifth to sixth decade of life and it generally presents as a painful breast lump. The histological features are characteristic with cribriform and acinar pattern of basaloid cells. It is triple negative tumor with CD117 and p63 positivity and excellent prognosis. PMID- 29449737 TI - Unexpected cause for duodenal obstruction: Brunner's gland hyperplasia. AB - Brunner's gland hyperplasia is a rare benign lesion arising from the duodenum. It is often an incidental finding on endoscopy with the majority of patients being asymptomatic. It may also present with various symptoms depending on location and tumor size, such as gastrointestinal bleeding, obstruction and abdominal pain. We report an unusual case of large Brunner's gland hyperplasia in 72-years old man, admitted to hospital for epigastric pain, recurrent vomiting and significantly weight loss. Upper endoscopy showed an obstructive submucosis tumour of the bulb. Abdominal computed tomography scan revealed a circumferential thickening and stenosing mass of the first part of the duodenum leading to severe obstruction. Though pre-operative biopsies were negative, imaging studies and endoscopy were strongly suggestive of malignancy and the patient underwent duodenocephalopancreatectomy. Brunner's gland hyperplasia may have unusual presentation, mimicking malignancy. Therefore, extensive pre-operative evaluation, including repetitive tumor biopsies, is necessary to avoid radical surgical procedure. PMID- 29449738 TI - Parotid gland involvement in Heerfordt syndrome: a case report. AB - Sarcoidosis is a multisystemic granulomatous disease characterized by the presence of noncaseating granulomas, the exact etiology of which is yet to be determined. Most of patients show granulomas located in the lungs or in the related lymph nodes. However, lesions can affect any organ. Noncaseating granulomas are not a pathognomonic sign of sarcoidosis, being observed also in other diseases, therefore the diagnosis is often of exclusion. We report a case of sarcoidosis with parotid gland involvement in the context of a Heerfordt syndrome, discussing about its clinical presentation, pathogenesis, pathology and differential diagnosis with other granulomatous diseases. PMID- 29449739 TI - Nasal metastasis as the first manifestation of a metachronous bilateral renal cell carcinoma. AB - Renal cell carcinoma is one of the most common tumours to spread by extranodal metastases to the head and neck. Metastatic renal cell carcinoma to the head and neck area has been demonstrated mostly in the paranasal sinuses, parotid gland, the mandible, larynx and hypopharinx. Renal cell carcinoma should be excluded whenever a metastatic lesion is encountered in the head and neck area, even if the metastatic lesion is the first clinical presentation. The diagnosis of metastatic RCC should be suspected in any patient with even a remote history of renal cell carcinoma. We report a case of 79 year old woman with recurrent episodes of rhinorrhea, headache, hyposmia and monolateral right epistaxis, with a history of RCC. We describe RCC nasal metastases in a metachronous bilateral neoplasm, in which a second occult lesion debuted with a homolateral nasal metastases, ten years after left nephrectomy. PMID- 29449740 TI - Does V600E BRAF mutation predict vinorelbine efficacy? A proof-of-concept from a lung micropapillary adenocarcinoma metastatic to the breast. AB - BRAF mutations occur in about 3% of all lung adenocarcinomas and V600E missense mutation characterizes about half of BRAF-mutated lung adenocarcinomas and is significantly associated with micropapillary pattern and shorter disease-free and overall survival rates. In this report, we report a challenging case of a patient with a metastatic micropapillary adenocarcinoma of the lung harbouring V600E BRAF mutation who experienced a surprising protracted clinical response to metronomic vinorelbine. The possible association between the V600E BRAF mutation pathway and the effective use of vinca alkaloid is discussed. PMID- 29449741 TI - Far Ultraviolet Spectroscopy of Old Novae I. V603 Aquila. AB - We present the results of a synthetic spectral analysis of the far ultraviolet archival IUE, HST and FUSE observations of the fast old nova V603 Aql, obtained some 90 years after its 1918 nova outburst. Our analysis utilizes the new Hubble FGS parallax distance for this nearly face-on old nova, a high white dwarf mass and a low reddening. Our analysis includes non-truncated optically thick accretion disks since V603 Aql is neither a polar nor an intermediate polar. Our synthetic spectral modeling of the FUSE and HST spectra analyzed separately indicate a mass transfer rate [Formula: see text] for the FUSE and HST spectra respectively, assuming a WD mass of 1.2M?. The mass accretion rate also depends on the assumed WD mass, and increases by a factor of two for a WD mass of 0.8M?. Combining the FUSE and HST spectra together lead to the same results. Potential implications are discussed. PMID- 29449742 TI - Isolation, Separation, and Preconcentration of Biologically Active Compounds from Plant Matrices by Extraction Techniques. AB - Development of efficient methods for isolation and separation of biologically active compounds remains an important challenge for researchers. Designing systems such as organomineral composite materials that allow extraction of a wide range of biologically active compounds, acting as broad-utility solid-phase extraction agents, remains an important and necessary task. Selective sorbents can be easily used for highly selective and reliable extraction of specific components present in complex matrices. Herein, state-of-the-art approaches for selective isolation, preconcentration, and separation of biologically active compounds from a range of matrices are discussed. Primary focus is given to novel extraction methods for some biologically active compounds including cyclic polyols, flavonoids, and oligosaccharides from plants. In addition, application of silica-, carbon-, and polymer-based solid-phase extraction adsorbents and membrane extraction for selective separation of these compounds is discussed. Potential separation process interactions are recommended; their understanding is of utmost importance for the creation of optimal conditions to extract biologically active compounds including those with estrogenic properties. PMID- 29449743 TI - Caregiver's Burden, Coping, and Psycho-Education in Indian Households with Single and Multiple-Affected Members with Schizophrenia. AB - There is considerable evidence that family psycho-education combined with pharmacological intervention for patients with schizophrenia increases family understanding of the illness, reduces the familial burden of care, and improves patient outcomes. However, no studies have determined whether the burden of care is greater for those families with more than one ill member (multiplex) than for families with a single-affected individual (simplex), and whether psycho educational programs should be adapted to meet the specific needs of multiplex families. This study was conducted at a tertiary care postgraduate teaching hospital in New Delhi, India. Caregivers in simplex [n = 50] and multiplex families [n = 30] were compared with regard to levels of burden, coping, and the impact of psycho-education on family functioning. All the caregiver participants attended eight bimonthly, psycho-educational intervention sessions. They were assessed on the Burden Assessment Schedule (BAS) and the Coping Check List (CCL) before and after psycho-education. Caregivers from the multiplex families reported significantly more burden on two domains of the BAS, but there were no significant differences between the groups with regard to coping on the CCL. Following psycho-education, significant improvement occurred in the majority of domains of the BAS and the CCL; the effect sizes varied by domain and family type. Multiplex families face a greater burden of care compared with simplex families. Currently, available psycho-education programs are moderately effective for such families. PMID- 29449744 TI - Laurdan and Di-4-ANEPPDHQ probe different properties of the membrane. AB - Lipid packing is a crucial feature of cellular membranes. Quantitative analysis of membrane lipid packing can be achieved using polarity sensitive probes whose emission spectrum depends on the lipid packing. However, detailed insights into the exact mechanisms that cause the changes in the spectra are necessary to interpret experimental fluorescence emission data correctly. Here, we analysed frequently used polarity sensitive probes, Laurdan and di-4-ANEPPDHQ, to test whether the underlying physical mechanisms of their spectral changes are the same and, thus, whether they report on the same physico-chemical properties of the cell membrane. Steady-state spectra as well as time-resolved emission spectra of the probes in solvents and model membranes revealed that they probe different properties of the lipid membrane. Our findings are important for the application of these dyes in cell biology. PMID- 29449745 TI - The Drawbacks of Project Funding for Epistemic Innovation: Comparing Institutional Affordances and Constraints of Different Types of Research Funding. AB - Over the past decades, science funding shows a shift from recurrent block funding towards project funding mechanisms. However, our knowledge of how project funding arrangements influence the organizational and epistemic properties of research is limited. To study this relation, a bridge between science policy studies and science studies is necessary. Recent studies have analyzed the relation between the affordances and constraints of project grants and the epistemic properties of research. However, the potentially very different affordances and constraints of funding arrangements such as awards, prizes and fellowships, have not yet been taken into account. Drawing on eight case studies of funding arrangements in high performing Dutch research groups, this study compares the institutional affordances and constraints of prizes with those of project grants and their effects on organizational and epistemic properties of research. We argue that the prize case studies diverge from project-funded research in three ways: 1) a more flexible use, and adaptation of use, of funds during the research process compared to project grants; 2) investments in the larger organization which have effects beyond the research project itself; and 3), closely related, greater deviation from epistemic and organizational standards. The increasing dominance of project funding arrangements in Western science systems is therefore argued to be problematic in light of epistemic and organizational innovation. Funding arrangements that offer funding without scholars having to submit a project proposal remain crucial to support researchers and research groups to deviate from epistemic and organizational standards.

AB - While all experts agreed that protein needs for performance are likely greater than believed in past generations, particularly for strength training athletes, and that dietary fat could sustain an active person through lower-intensity training bouts, current research still points to carbohydrate as an indispensable energy source for high-intensity performance. PMID- 29449747 TI - CONTINUOUS CALIBRATION IMPROVEMENT: LANDSAT 5 THROUGH LANDSAT 8. AB - Launched in February 2013, the Operational Land Imager (OLI) on-board Landsat 8 continues to perform exceedingly well and provides high science quality data globally. Several design enhancements have been made in the OLI instrument relative to prior Landsat instruments: pushbroom imaging which provides substantially improved Signal-to-Noise Ratio (SNR), spectral bandpasses refinement to avoid atmospheric absorption features, 12 bit data resolution to provide a larger dynamic range that limits the saturation level, a set of well designed onboard calibrators to monitor the stability of the sensor. Some of these changes such as refinements in spectral bandpasses compared to earlier Landsats and well-designed on-board calibrator have a direct impact on the improved radiometric calibration performance of the instrument from both the stability of the response and the ability to track the changes. The on-board calibrator lamps and diffusers indicate that the instrument drift is generally less than 0.1% per year across the bands. The refined bandpasses of the OLI indicate that temporal uncertainty of better than 0.5% is possible when the instrument is trended over vicarious targets such as Pseudo Invariant Calibration Sites (PICS), a level of precision that was never achieved with the earlier Landsat instruments. The stability measurements indicated by on-board calibrators and PICS agree much better compared to the earlier Landsats, which is very encouraging and bodes well for the future Landsat missions too.

AB - During Eugene Garfield's (EG's) lengthy career as information scientist, he published about 1500 papers. In this study, we use the impressive oeuvre of EG to introduce a new type of bibliometric networks: keyword co-occurrences networks based on the context of citations, which are referenced in a certain paper set (here: the papers published by EG). The citation context is defined by the words which are located around a specific citation. We retrieved the citation context from Microsoft Academic. To interpret and compare the results of the new network type, we generated two further networks: co-occurrence networks which are based on title and abstract keywords from (1) EG's papers and (2) the papers citing EG's publications. The comparison of the three networks suggests that papers of EG and citation contexts of papers citing EG are semantically more closely related to each other than to titles and abstracts of papers citing EG. This result accords with the use of citations in research evaluation that is based on the premise that citations reflect the cognitive influence of the cited on the citing publication. PMID- 29449750 TI - Are you in top 1% (10/00)? AB - A new simple bibliometric indicator is based on the number of highly cited papers (as defined by WoS(r)). It can be used to assess individuals, journals and universities. Unlike most other citation-based-indicators it equalizes the chances of young scientists (vs. their more experienced colleagues) and of scientists working in less-popular disciplines. The ranking of scientists based on the new indicator is not correlated with the rankings based upon the number of citations or on the Hirsch-index. PMID- 29449749 TI - Reference publication year spectroscopy (RPYS) of Eugene Garfield's publications. AB - Which studies, theories, and ideas have influenced Eugene Garfield's scientific work? Recently, the method reference publication year spectroscopy (RPYS) has been introduced, which can be used to answer this and related questions. Since then, several studies have been published dealing with the historical roots of research fields and scientists. The program CRExplorer (http://www.crexplorer.net) was specifically developed for RPYS. In this study, we use this program to investigate the historical roots of Eugene Garfield's oeuvre. PMID- 29449751 TI - Betweenness and diversity in journal citation networks as measures of interdisciplinarity-A tribute to Eugene Garfield. AB - Journals were central to Eugene Garfield's research interests. Among other things, journals are considered as units of analysis for bibliographic databases such as the Web of Science and Scopus. In addition to providing a basis for disciplinary classifications of journals, journal citation patterns span networks across boundaries to variable extents. Using betweenness centrality (BC) and diversity, we elaborate on the question of how to distinguish and rank journals in terms of interdisciplinarity. Interdisciplinarity, however, is difficult to operationalize in the absence of an operational definition of disciplines; the diversity of a unit of analysis is sample-dependent. BC can be considered as a measure of multi-disciplinarity. Diversity of co-citation in a citing document has been considered as an indicator of knowledge integration, but an author can also generate trans-disciplinary-that is, non-disciplined-variation by citing sources from other disciplines. Diversity in the bibliographic coupling among citing documents can analogously be considered as diffusion or differentiation of knowledge across disciplines. Because the citation networks in the cited direction reflect both structure and variation, diversity in this direction is perhaps the best available measure of interdisciplinarity at the journal level. Furthermore, diversity is based on a summation and can therefore be decomposed; differences among (sub)sets can be tested for statistical significance. In the appendix, a general-purpose routine for measuring diversity in networks is provided. PMID- 29449752 TI - Capturing 'R&D excellence': indicators, international statistics, and innovative universities. AB - Excellent research may contribute to successful science-based technological innovation. We define 'R&D excellence' in terms of scientific research that has contributed to the development of influential technologies, where 'excellence' refers to the top segment of a statistical distribution based on internationally comparative performance scores. Our measurements are derived from frequency counts of literature references ('citations') from patents to research publications during the last 15 years. The 'D' part in R&D is represented by the top 10% most highly cited 'excellent' patents worldwide. The 'R' part is captured by research articles in international scholarly journals that are cited by these patented technologies. After analyzing millions of citing patents and cited research publications, we find very large differences between countries worldwide in terms of the volume of domestic science contributing to those patented technologies. Where the USA produces the largest numbers of cited research publications (partly because of database biases), Switzerland and Israel outperform the US after correcting for the size of their national science systems. To tease out possible explanatory factors, which may significantly affect or determine these performance differentials, we first studied high-income nations and advanced economies. Here we find that the size of R&D expenditure correlates with the sheer size of cited publications, as does the degree of university research cooperation with domestic firms. When broadening our comparative framework to 70 countries (including many medium-income nations) while correcting for size of national science systems, the important explanatory factors become the availability of human resources and quality of science systems. Focusing on the latter factor, our in-depth analysis of 716 research intensive universities worldwide reveals several universities with very high scores on our two R&D excellence indicators. Confirming the above macro-level findings, an in-depth study of 27 leading US universities identifies research expenditure size as a prime determinant. Our analytical model and quantitative indicators provides a supplementary perspective to input-oriented statistics based on R&D expenditures. The country-level findings are indicative of significant disparities between national R&D systems. Comparing the performance of individual universities, we observe large differences within national science systems. The top ranking 'innovative' research universities contribute significantly to the development of advanced science-based technologies. PMID- 29449753 TI - Do younger Sleeping Beauties prefer a technological prince? AB - In this paper we investigate recent Sleeping Beauties cited in patents (SB SNPRs). We find that the increasing trend of the relative number of SBs stopped around 1998. Moreover, we find that the time lag between the publication year of the SB-SNPRs and their first citation in a patent is becoming shorter in recent years. Our observations also suggest that, on average, in the more recent years SBs are awakened increasingly earlier by a 'technological prince' rather than by a 'scientific prince'. These observations suggest that SBs with technological importance are 'discovered' earlier in an application-oriented context. Then, because of this earlier recognized technological relevance, papers may be cited also earlier in a scientific context. Thus early recognized technological relevance may 'prevent' papers to become an SB. The scientific impact of Sleeping Beauties is generally not necessarily related to the technological importance of the SBs, as far as measured with number and impact of the citing patents. The analysis of the occurrence of inventor-author relations as well as the citation years of inventor-author patents suggest that the scientific awakening of Sleeping Beauties only rarely occurs by inventor-author self-citation.

AB - Automated monitoring of behaviour can offer a wealth of information in circumstances where observing behaviour is difficult or time consuming. However, this often requires attaching monitoring devices to the animal which can alter behaviour, potentially invalidating any data collected. Birds often show increased preening and energy expenditure when wearing devices and, especially in laying hens, there is a risk that individuals wearing devices will attract aggression from conspecifics. We studied the behavioural and physiological response of 20 laying hens to backpacks containing monitoring devices fastened with elastic loops around the wing base. We hypothesised that backpacks would lead to a stress-induced decrease in peripheral temperature, increased preening, more aggression from conspecifics, and reduced bodyweights. This was evaluated by thermography of the eye and comb (when isolated after fitting backpacks), direct observations of behaviour (when isolated, when placed back into the group, and on later days), and weighing (before and after each 7-day experimental period). Each hen wore a backpack during one of the two experimental periods only and was used as her own control. Contrary to our hypothesis, eye temperature was higher when hens wore a backpack (No backpack: 30.2 degrees C (IQR: 29.0-30.6) vs. Backpack: 30.9 degrees C (IQR: 30.0-32.0), P < 0.001). Eye temperature of hens wearing a backpack was strongly correlated to the time spent preening (rs = 0.8, P < 0.001), suggesting that the higher temperatures may have been due to preening itself, or to a low head position or decreased heat dissipation when preening under the wings. Aggressive behaviour was very rare and no effect of the backpacks was found. In line with our hypothesis, backpacks increased preening on the day of fitting, both when isolated (No backpack: 0% (IQR: 0-1) vs. Backpack: 22% (IQR: 1-43), P < 0.01) and when back in the group (No backpack: 0% (IQR: 0 27) vs. Backpack: 43% (IQR: 5-77), P < 0.001). However, no effect on preening was observed 2-7 days afterwards. Other behavioural changes suggested that on the day of fitting hens prioritized attempts to (re)move the backpack and were less attentive to their surroundings. However, only equipment pecking (i.e., pecking the backpack or leg rings) was still affected 2-7 days after fitting (No backpack: 0 pecks/hen/minute (IQR: 0-0), vs. Backpack: 0 (IQR: 0-0.07), P < 0.05). We found no effect of our backpacks on bodyweight. In conclusion, our backpacks seem suitable to attach monitoring equipment to hens with only a very minor effect on their behaviour after a short acclimation period (<=2 days).

AB - In this study, human feces were hydrothermal liquefied and converted into biocrude over Ni-Tm/TiO2 catalyst. The influence of catalysts, reaction temperature, and holding time on the distribution of products and element content of biocrude was assessed. The biocrude yield increased to 53.16% with a reaction temperature of 330 degrees C, a holding time of 30 min, and adding Ni-Tm/TiO2 catalyst while the liquefaction conversion peaked at 89.61%. The biocrude had an HHV of 36.64 MJ/kg and was similar to heavy crude oil. The biocrude is rich in fatty acid amides, esters, and oxygen-containing-only heteroatom-ring compounds as well as some nitrogen-containing heteroatom-ring compounds. The main gaseous products were CO2, CH4, and C2H6. Hydrothermal liquefaction over Ni-Tm/TiO2 catalyst could be a potential method to handle human excrement treatment and produce biofuel. PMID- 29449756 TI - Fluorescence lifetime microscopy with a time- and space-resolved single-photon counting detector. AB - We have recently developed a wide-field photon-counting detector (the H33D detector) having high-temporal and high-spatial resolutions and capable of recording up to 500,000 photons per sec. Its temporal performance has been previously characterized using solutions of fluorescent materials with different lifetimes, and its spatial resolution using sub-diffraction objects (beads and quantum dots). Here we show its application to fluorescence lifetime imaging of live cells and compare its performance to a scanning confocal TCSPC approach. With the expected improvements in photocathode sensitivity and increase in detector throughput, this technology appears as a promising alternative to the current lifetime imaging solutions. PMID- 29449758 TI - An assessment of forest biomass maps in Europe using harmonized national statistics and inventory plots. AB - Maps of aboveground forest biomass based on different input data and modelling approaches have been recently produced for Europe, opening up the possibility for several applications and products not obtainable by summary statistics. However, the accuracy assessment of the existing maps is limited by the lack of reference data consistent over the study region and representative of the maps cells. Here, we used harmonized forest biomass data for 26 European countries derived by National Forest Inventories using a common biomass definition and estimator to assess four biomass maps. The assessment was performed at regional, national and sub-national scales using harmonized statistics derived from almost half million ground plot measurements, and at pixel level using a subset of 22,166 plots covering most European forest types. The field plots were temporally aligned with the maps using growth rates and further screened using an innovative approach based on tree cover variability to remove the plots not representative of the map cells. The harmonized reference data showed that all maps tended to overestimate at low biomass (<100 Mg ha-1) and underestimate at medium - high biomass (>100 Mg ha-1), resulting in an overall negative bias (23-43 Mg ha-1 at national level) relative to the harmonized estimates. The maps relative errors ranged from 29% to 40% at national level and increased at higher resolutions, reaching 58-67% at pixel level. We also assessed the effect of the harmonization of the national statistics and report that the harmonized biomass values present significant differences compared to the national estimates for 14 countries, and provide a slightly higher stock (+3.8%) at European scale. We show that harmonized and representative reference data are essential to properly assess the accuracy of biomass maps, and we further identify the factors affecting the maps performance and provide indications for their improvements.

AB - A method for the asymmetric synthesis of the disaccharide portion of SCH-47554 has been developed in 6 steps. The route is shorter than the reported route to a related disaccharide. The route involves the use of the Noyori reduction to establish the asymmetry of the d- and l-sugar portion of the molecule. Diastereoselective Pd-glycosylation reaction and subsequent post-glycosylation transformation are used to establish the remaining stereocenter. PMID- 29449760 TI - Pediatric Psychologists' Career Satisfaction: 2015 Society of Pediatric Psychology Workforce Survey Results. AB - : Little is known about the career satisfaction of pediatric psychologists, who specialize in psychological research, teaching, and clinical service in the context of pediatric healthcare. As part of the larger Society of Pediatric Psychology Workforce Survey and in collaboration with the American Psychological Association Center for Workforce Studies, this study aimed to: (1) describe the career domains which pediatric psychologists perceive to be important and their satisfaction in each domain, and (2) compare satisfaction of pediatric psychologists across work settings, number of positions, appointment duration, professional roles, career stage, academic rank, and gender. Responses from 336 pediatric psychologists demonstrated high career satisfaction. Domains of career satisfaction that received mean scores indicating high importance include balance of work and personal lives, peer/collegial support, and flexibility and choice in the workplace, but on average respondents reported being only somewhat satisfied in these domains. Total satisfaction scores were significantly higher among pediatric psychologists in 9-10 month appointments, primarily research careers, and at higher academic ranks, but scores were similar across employment settings and genders. To enhance career satisfaction and retention, pediatric psychologists may seek additional mentorship or explore new employment roles, and administrators and managers may consider adopting workplace policies or making environmental changes that could address specific areas of need. Public Significance Statement: This study suggests that overall, pediatric psychologists are highly satisfied with their employment. However, there may be some important aspects of their work that could be more satisfying. The findings have implications for identifying professional development strategies that can maintain or enhance satisfaction. PMID- 29449761 TI - Active Localization and Tracking of Needle and Target in Robotic Image-Guided Intervention Systems. AB - This paper describes a framework of algorithms for the active localization and tracking of flexible needles and targets during image-guided percutaneous interventions. The needle and target configurations are tracked by Bayesian filters employing models of the needle and target motions and measurements of the current system state obtained from an intra-operative imaging system which is controlled by an entropy-minimizing active localization algorithm. Versions of the system were built using particle and unscented Kalman filters and their performance was measured using both simulations and hardware experiments with real magnetic resonance imaging data of needle insertions into gel phantoms. Performance of the localization algorithms is given in terms of accuracy of the predictions and computational efficiency is discussed. PMID- 29449757 TI - Why and how the early-life environment affects development of coping behaviours. AB - Understanding the ways in which individuals cope with threats, respond to challenges, make use of opportunities and mediate the harmful effects of their surroundings is important for predicting their ability to function in a rapidly changing world. Perhaps one of the most essential drivers of coping behaviour of adults is the environment experienced during their early-life development. Although the study of coping, defined as behaviours displayed in response to environmental challenges, has a long and rich research history in biology, recent literature has repeatedly pointed out that the processes through which coping behaviours develop in individuals are still largely unknown. In this review, we make a move towards integrating ultimate and proximate lines of coping behaviour research. After broadly defining coping behaviours (1), we review why, from an evolutionary perspective, the development of coping has become tightly linked to the early-life environment (2), which relevant developmental processes are most important in creating coping behaviours adjusted to the early-life environment (3), which influences have been shown to impact those developmental processes (4) and what the adaptive significance of intergenerational transmission of coping behaviours is, in the context of behavioural adaptations to a fast changing world (5). Important concepts such as effects of parents, habitat, nutrition, social group and stress are discussed using examples from empirical studies on mammals, fish, birds and other animals. In the discussion, we address important problems that arise when studying the development of coping behaviours and suggest solutions. PMID- 29449762 TI - Fast covariance estimation for sparse functional data. AB - Smoothing of noisy sample covariances is an important component in functional data analysis. We propose a novel covariance smoothing method based on penalized splines and associated software. The proposed method is a bivariate spline smoother that is designed for covariance smoothing and can be used for sparse functional or longitudinal data. We propose a fast algorithm for covariance smoothing using leave-one-subject-out cross-validation. Our simulations show that the proposed method compares favorably against several commonly used methods. The method is applied to a study of child growth led by one of coauthors and to a public dataset of longitudinal CD4 counts.

PMID- 29449764 TI - The effect of manual therapy and neuroplasticity education on chronic low back pain: a randomized clinical trial. AB - Objective: To determine if a neuroplasticity educational explanation for a manual therapy technique will produce a different outcome compared to a traditional mechanical explanation. Methods: Sixty-two patients with chronic low back pain (CLBP) were recruited for the study. Following consent, demographic data were obtained as well as pain ratings for low back pain (LBP) and leg pain (Numeric Pain Rating Scale), disability (Oswestry Disability Index), fear-avoidance (Fear Avoidance-Beliefs Questionnaire), forward flexion (fingertips-to-floor), and straight leg raise (SLR) (inclinometer). Patients were then randomly allocated to receive one of two explanations (neuroplasticity or mechanical), a manual therapy technique to their lumbar spine, followed by post-intervention measurements of LBP, leg pain, forward flexion, and SLR. Results: Sixty-two patients (female 35 [56.5%]), with a mean age of 60.1 years and mean duration of 9.26 years of CLBP participated in the study. There were no statistically significant interactions for LBP (p = .325), leg pain (p = .172), and trunk flexion (p = .818) between the groups, but SLR showed a significant difference in favor of the neuroplasticity explanation (p = .041). Additionally, the neuroplasticity group were 7.2 times (95% confidence interval = 1.8-28.6) more likely to improve beyond the MDC on the SLR than participants in the mechanical group. Discussion: The results of this study show that a neuroplasticity explanation, compared to a traditional biomechanical explanation, resulted in a measureable difference in SLR in patients with CLBP when receiving manual therapy. Future studies need to explore if the increase in SLR correlated to changes in cortical maps of the low back. PMID- 29449765 TI - Application of the McKenzie system of Mechanical Diagnosis and Therapy (MDT) in patients with shoulder pain; a prospective longitudinal study. AB - Objectives: The primary objective was to determine if the pain and function response to the McKenzie system of Mechanical Diagnosis and Therapy (MDT) differs by MDT classification category at two and four weeks following the start of MDT treatment for shoulder complaints. The secondary objective was to describe the frequency of discharge over time by MDT classification. Methods: International, MDT-trained study collaborators recruited 93 patients attending physiotherapy for rehabilitation of a shoulder problem. The Numeric Pain Rating Scale (NPRS) and the Upper Extremity Functional Index (UEFI) were collected at the initial assessment and two and four weeks after treatment commenced. A two-way mixed model analysis of variance with planned pairwise comparisons was performed to identify where the differences between MDT classification groups actually existed. Results: The Derangement and Spinal classifications had significantly lower NPRS scores than the Dysfunction group at week 2 and week 4 (p < 0.05). The Derangement and Spinal classifications had significantly higher UEFI scores than the Dysfunction group at week 2 and week 4 (p < 0.05). The frequency of discharge at week 2 was 37% for both Derangement and Spinal classifications, with no discharges for the Dysfunction classification at this time point. The frequency of discharge at week 4 was 83, 82 and 15% for the Derangement, Spinal and Dysfunction classifications, respectively. Discussion: Classifying patients with shoulder pain using the MDT system can impact treatment outcomes and the frequency of discharge. When MDT-trained clinicians are allowed to match the intervention to a specific MDT classification, the outcome is aligned with the response expectation of the classification.Level of Evidence: 2b. PMID- 29449766 TI - Directional preference of the wrist: a preliminary investigation. AB - Background: Directional preference is a phenomenon that occurs in musculoskeletal disorders. It is associated with improved symptomatic and functional outcomes. Research has shown a 90% increase in the identification of directional preference in the peripheral joints between 2006 and 2012. There is currently no research analyzing if predictive variables exist for establishing directional preference. Case Description: This report presents 19 consecutive patients with wrist pain. These patients were evaluated using a mechanical diagnosis and therapy (MDT) based assessment. Patients were classified into the mechanical syndromes Derangement, Dysfunction, Postural, and Other. Patients classified with wrist Derangement were assessed for the presence of directional preference. Secondary analysis of predetermined variables was performed for association with directional preference. One case description was included to demonstrate MDT assessment, treatment, and clinical reasoning. Results: Of the 19 patients evaluated, 15 (79%) were classified as having wrist Derangement. All patients with wrist Derangement demonstrated directional preference. Eight movements were found to establish directional preference. Each was unique with varying degrees of direction, load, and force. Discussion: This report found directional preference to be higher (79%) than previously reported values. Historical and physical examination findings were analyzed to determine if there were associated variables of directional preference. Excessive mechanical stress was found to be the most associated factor in predicting directional preference. These findings may lead to a greater understanding of peripheral MDT assessment, which may lead to increased identification of directional preference and improved patient outcomes. Level of Evidence: 4. PMID- 29449767 TI - Novel treatment of lateral ankle sprains using the Mulligan concept: an exploratory case series analysis. AB - Objective: The purpose of this study was to examine the effect of the Mulligan Concept (MC) Mobilization with movement (MWM) in the treatment of clinically diagnosed acute lateral ankle sprains in competitive athletes. Methods: A prospective case series of 5 adolescent patients, ages ranging from 14 to 18 years (mean = 15.8 +/- 1.64), that suffered an acute lateral ankle sprain (LAS). Patients were treated with the MC lateral ankle MWM. Mobilization was directed at the distal fibula or, using a modified MWM, 2-3 inches proximal to the distal fibula. Using paired t-tests and descriptive statistics (mean and standard deviation) results were analyzed. Results: Treatment lasted an average of 9 days (mean = 9.2, +/-SD 3.96) from intake to discharge. During that time frame, patients reported decreases in pain on the numeric pain rating scale (NRS), disability on the Disablement in the Physically Active (DPA) scale and an increase in function on the patient-specific functional scale (PSFS); and an immediate decrease in pain on the NRS within the first treatment. The minimal detectable change for the PSFS and NRS were exceeded from intake to discharge. Additionally, the minimally clinical important differences were exceeded on the NRS and DPA scale. Discussion: The evidence presented in this Level-4 case series supports the use of the MC lateral ankle MWM to treat patients diagnosed with acute grade II LAS. Patients in this case series reported immediate decreases in pain and immediate increases in function. Therefore, further investigation of the MC lateral ankle MWM is warranted. PMID- 29449768 TI - Grade-IV inferior glenohumeral mobilization does not immediately alter shoulder and scapular muscle activity: a repeated-measures study in asymptomatic individuals. AB - Objectives: To assess: (1) the presence of any carry-over effect between interventions; (2) the immediate effects of inferior shoulder mobilization on shoulder and scapular muscle activity; and (3) to compare muscle activity response between the control and mobilization conditions. Repeated measures, cross-over, pre-post intervention study with sample of convenience. Methods: Twenty-two asymptomatic individuals performed 10 repetitions of shoulder abduction before and after the control and mobilization, with a dosage of three sets of 30-s duration, with grade-IV. The order of intervention was randomized. Surface electromyography was used for recording activity of upper and lower trapezius; anterior, middle and posterior deltoids; supraspinatus; infraspinatus; and serratus anterior. Repeated measures mixed-model analysis of variance was used to assess immediate changes in muscle activity levels following inferior shoulder mobilization. Statistical parametric mapping (SPM) was used for comparing muscle activity waveforms between control and mobilization conditions throughout the range of motion. Results: No systematic changes in muscle activity levels were found between: (1) baseline and follow-up for each condition, at the concentric and eccentric phases of shoulder abduction; (2) control and mobilization conditions during the concentric and eccentric phases of shoulder abduction. SPM results suggested no differences in muscle activity pattern between conditions. Conclusions: Inferior shoulder mobilization did not produce immediate effects on shoulder and scapular muscle activity. It is possible that the dose used was insufficient to generate an immediate neuromuscular response to the mobilization. PMID- 29449769 TI - Translational manipulation under anesthesia for patients with frozen shoulder: a case series study with five-year health care utilization and post-manipulative arthroscopic findings. AB - Study Design: Case series study. Objectives: Although there have been no reported complications from translational manipulation under anesthesia (tMUA) for individuals with adhesive capsulitis (AC) there are no cases reporting surgical findings post tMUA. Also, there are no studies evaluating health care utilization following tMUA. The purpose of this study was to: (1) report clinical outcomes following tMUA, (2) describe relevant health care costs and utilization following tMUA, and (3) summarize findings from two cases receiving joint arthroscopy following tMUA. Methods: Fourteen Individuals with AC underwent tMUA. Range of motion (ROM) and Shoulder Pain and Disability Index (SPADI) values were collected at baseline and six weeks follow-up. Shoulder-related health care cost and utilization were analyzed for a five-year period following tMUA. Two additional patients with AC underwent tMUA followed by arthroscopic assessment for evidence of iatrogenic injury. Results: Thirteen patients completed the six-week follow up. Mean change scores for ROM and SPADI values were flexion; +38.5 degrees , abduction; +71.1 degrees , external rotation (shoulder abducted); +49.8 degrees , internal rotation (shoulder abducted); +26.6 degrees , SPADI scores; +44.4. 13 patient records were analyzed for health care utilization. Ten of the 13 patients utilized no additional shoulder-related health care. Surgical evaluation revealed no evidence of iatrogenic injury. Discussion: Clinical outcomes were similar to previous studies. Utilization data indicated that for the majority of patients, little shoulder-related health care was utilized. Surgical evaluation provided further evidence that tMUA performed by a physical therapist is safe. Future research will be required to establish a causal relationship between tMUA and the results observed in this study. Level of Evidence: Therapy, Level 4. PMID- 29449770 TI - Adverse events following cervical manipulative therapy: consensus on classification among Dutch medical specialists, manual therapists, and patients. AB - Objectives: To obtain consensus-based agreement on a classification system of adverse events (AE) following cervical spinal manipulation. The classification system should be comprised of clear definitions, include patients' and clinicians' perspectives, and have an acceptable number of categories. Methods: Design: A three-round Delphi study. Participants: Thirty Dutch participants (medical specialists, manual therapists, and patients) participated in an online survey. Procedure: Participants inventoried AE and were asked about their preferences for either a three- or a four-category classification system. The identified AE were classified by two analysts following the International Classification of Functioning, Disability and Health (ICF), and the International Classification of Diseases and Related Health Problems (ICD-10). Participants were asked to classify the severity for all AE in relation to the time duration. Results: Consensus occurred in a three-category classification system. There was strong consensus for 16 AE in all severities (no, minor, and major AE) and all three time durations [hours, days, weeks]. The 16 AE included anxiety, flushing, skin rash, fainting, dizziness, coma, altered sensation, muscle tenderness, pain, increased pain during movement, radiating pain, dislocation, fracture, transient ischemic attack, stroke, and death. Mild to strong consensus was reached for 13 AE. Discussion: A consensus-based classification system of AE is established which includes patients' and clinicians' perspectives and has three categories. The classification comprises a precise description of potential AE in accordance with internationally accepted classifications. After international validation, clinicians and researchers may use this AE classification system to report AE in clinical practice and research. PMID- 29449771 TI - The effectiveness of manual physical therapy interventions in pediatric patients with anterior hip pain: a retrospective study. AB - Objectives: The purposes of this study were to: (1) assess the benefit of adding manual therapy (MT) to physical therapy care in pediatric patients with anterior hip pain; (2) assess the relative risk of adverse reactions when MT is used; and (3) report the types of MT used. Methods: This study was a retrospective chart review of patients treated in a hospital-based sports medicine clinic. The charts of 201 patients (mean age = 14.23 +/- 2.15 years) met the inclusion criteria and were reviewed. Patients were grouped into those who received MT during their episode of care, and those who did not. Pain efficiency (change in pain/number of visits), number and type of adverse reactions, as well as frequency and type of manual therapy interventions used, were the outcomes of interest. Results: The mean pain efficiency was significantly less if manual therapy was performed (MT = 0.60 [95% CI 0.47-0.72], no MT = 0.80 [95% CI 0.71-0.90] p = 0.01). There was no significant difference between groups in risk of adverse reactions (MT = 5, no MT = 5). The number of visits was significantly different between groups (MT = 9.43 +/- 3.9 sessions, and no MT = 7.6 +/- 5.2 sessions). Discussion: MT did not increase the risk of an adverse reaction in pediatric patients with anterior hip pain. While it appears to be a safe intervention, it did not improve pain efficiency or patient adherence. Future research should be performed to assess the effectiveness of MT, when performed by skilled therapists, in pediatric patients with hip pain in a controlled manner.Level of Evidence: 3b. PMID- 29449772 TI - Differential examination, diagnosis and management for tingling in toes: fellow's case problem. AB - Background: The diagnosis of chronic exertional compartment syndrome can be challenging as other pathologies involving bone, muscle, nerve and vascular structures can mimic the syndrome. The purpose of this Fellow's Case Problem is to describe the clinical decision-making and physical therapy differential diagnosis regarding a 25-year-old patient with un-resolved neurovascular complaints following chronic exertional compartment syndrome surgical release. Diagnosis: After surgery, the patient's previous complaint of numbness and tingling in the plantar surfaces of her first and second toes of right foot was still present. The patient's concordant symptoms in toes were reproduced proximally in the lumbar spine and distally in the tarsal tunnel. Discussion: The lumbar spine can refer symptoms to the lower extremities and needs to be ruled out as the source of the patient's complaint whenever neurovascular symptoms such as numbness and tingling are present. The discovery of the relationship of the lumbar spine with the tingling in the toes addressed one of the patient's primary concerns that was not resolved from the surgery. Level of Evidence: 4. PMID- 29449773 TI - Potential Breast Anticancer Drug Targets Revealed by Differential Gene Regulatory Network Analysis and Molecular Docking: Neoadjuvant Docetaxel Drug as a Case Study. AB - Understanding gene-gene interaction and its causal relationship to protein protein interaction is a viable route for understanding drug action at the genetic level, which is largely hindered by inability to robustly map gene regulatory networks. Here, we use biological prior knowledge of family-to-family gene interactions available in the KEGG database to reveal individual gene-to gene interaction networks that underlie the gene expression profiles of 2 cell line data sets, sensitive and resistive to neoadjuvant docetaxel breast anticancer drug. Comparison of the topology of the 2 networks revealed that the resistant network is highly connected with 2 large domains of connectivity: one in which the RAF1 and MAP2K2 genes form hubs of connectivity and another in which the RAS gene is highly connected. On the contrary, the sensitive network is highly disrupted with a lower degree of connectivity. We investigated the interactions of the neoadjuvant docetaxel drug with the protein chains encoded by gene-gene interactions that underlie the disruption of the sensitive network topology using protein-protein and drug-protein docking techniques. We found that the sensitive network is likely to be disrupted by interaction of the neoadjuvant docetaxel drug with the DAXX and FGR1 proteins, which is consistent with the observed accumulation of cytoplasmic DAXX and overexpression of FGR1 precursors in cancer cell lines. This indicates that the DAXX and FGR1 proteins could be potential targets for the neoadjuvant docetaxel drug. The work, therefore, provides a new route for understanding the effect of the drug mode of action from the viewpoint of the change in the topology of gene-gene regulatory networks and provides a new avenue for bridging the gap between gene-gene interactions and protein-protein interactions which could have deep implications on mainstream drug development protocols.

AB - Background: Cancer is one of the major heterogeneous disease with high morbidity and mortality with poor prognosis. Elevated levels of reactive oxygen species (ROS), alteration in redox balance, and deregulated redox signaling are common hallmarks of cancer progression and resistance to treatment. Mitochondria contribute mainly in the generation of ROS during oxidative phosphorylation. Elevated levels of ROS have been detected in cancers cells due to high metabolic activity, cellular signaling, peroxisomal activity, mitochondrial dysfunction, activation of oncogene, and increased enzymatic activity of oxidases, cyclooxygenases, lipoxygenases, and thymidine phosphorylases. Cells maintain intracellular homeostasis by developing an immense antioxidant system including catalase, superoxide dismutase, and glutathione peroxidase. Besides these enzymes exist an important antioxidant glutathione and transcription factor Nrf2 which contribute in balancing oxidative stress. Reactive oxygen species-mediated signaling pathways activate pro-oncogenic signaling which eases in cancer progression, angiogenesis, and survival. Concomitantly, to maintain ROS homeostasis and evade cancer cell death, an increased level of antioxidant capacity is associated with cancer cells. Conclusions: This review focuses the role of ROS in cancer survival pathways and importance of targeting the ROS signal involved in cancer development, which is a new strategy in cancer treatment.

AB - Prion protein (PrP) is a biomolecule that is involved in neuronal signaling, myelinization, and the development of neurodegenerative diseases. In the cell, PrP is shed by the ADAM10 protease. This process generates PrP molecules that lack glycophosphatidylinositol anchor, and these molecules incorporate into toxic aggregates and neutralize toxic oligomers. Due to this dual role, these molecules are important biomarkers for neurodegenerative diseases. In this review, we present shed PrP as a potential biomarker, with a focus on PrP226*, which may be the main biomarker for predicting neurodegenerative diseases in humans. PMID- 29449777 TI - A Homogeneous Time-Resolved Fluorescence Immunoassay Method for the Measurement of Compound W. AB - Objective: Using compound W (a 3,3'-diiodothyronine sulfate [T2S] immuno crossreactive material)-specific polyclonal antibodies and homogeneous time resolved fluorescence immunoassay assay techniques (AlphaLISA) to establish an indirect competitive compound W (ICW) quantitative detection method. Method: Photosensitive particles (donor beads) coated with compound W or T2S and rabbit anti-W antibody were incubated with biotinylated goat anti-rabbit antibody. This constitutes a detection system with streptavidin-coated acceptor particle. We have optimized the test conditions and evaluated the detection performance. Results: The sensitivity of the method was 5 pg/mL, and the detection range was 5 to 10 000 pg/mL. The intra-assay coefficient of variation averages <10% with stable reproducibility. Conclusions: The ICW-AlphaLISA shows good stability and high sensitivity and can measure a wide range of compound W levels in extracts of maternal serum samples. This may have clinical application to screen congenital hypothyroidism in utero. PMID- 29449776 TI - Nkx2-3-A Slippery Slope From Development Through Inflammation Toward Hematopoietic Malignancies. AB - The development of peripheral lymphoid tissues from the mesoderm is the result of a complex convergence combining lymphohematopoietic differentiation with the local specification of nonhematopoietic mesenchymal components. Although the various transcriptional regulators with fate-determining effects in diversifying the mobile leukocyte subsets have been thoroughly studied and identified, the tissue-specific determinants promoting the regional differentiation of resident mesenchyme are less understood. Of these factors, various members of the NK-class Nkx paralogues have emerged as key regulators for the organogenesis of spleen and mucosal lymphoid tissues, and recent data have also indicated their involvement in various pathological events, including gut inflammation and hematopoietic malignancies. Here, we summarize available data on the roles of Nkx2-3 in lymphoid tissue development and discuss its possible value as a developmental marker and disease-associated pathogenic trait. PMID- 29449778 TI - Why Do Those With Long-Term Substance Use Disorders Stop Abusing Substances? A Qualitative Study. AB - Although a significant proportion of adults recover from substance use disorders (SUDs), little is known about how they reach this turning point or why they stop using. The purpose of the study was to explore the factors that influence reasoning and decision making about quitting substance use after a long-term SUD. Semistructured interviews were conducted with 18 participants, each of whom had been diagnosed with a SUD and had been abstinent for at least 5 years. A resource group of peer consultants in long-term recovery from SUDs contributed to the study's planning, preparation, and initial analyses. Participants recalled harmful consequences and significant events during their years of substance use. Pressure and concern from close family members were important in their initial efforts to abstain from substance use. Being able to imagine a different life, and the awareness of existing treatment options, promoted hope and further reinforced their motivation to quit. Greater focus on why those with SUDs want to quit may help direct treatment matching; treatment completion may be more likely if the person's reasons for seeking help are addressed. PMID- 29449780 TI - Tubular Adenoma of the Breast: A Clinicopathologic Study of a Series of 9 Cases. AB - Tubular adenoma of the breast is one of the most rare benign neoplasms, accounting for only 0.13% to 1.7% of all breast benign tumors. Little is known about this rare neoplasm as the current literature offers only some case reports or a few number of small series. The aim of our study is to provide some clinicopathologic features of the breast tubular adenoma. We retrospectively analyzed at our department of pathology all cases of breast tubular adenomas confirmed by immunohistochemistry over a period of 9 years (2009-2017). Nine cases of breast tubular adenoma have been recorded, with an average age of 31.44 years. Five tumors were located at the right side (55.55%), and most cases had suspicious aspects on imaging techniques (6 cases out of 9). The diagnosis has been made on 5 resected specimens (lumpectomy) and on 4 core needle biopsies. The tumor size ranged from 0.9 to 7 cm (mean size of 3.08 cm) and had well circumscribed margins with elastic consistency. The histopathologic analysis showed a typical pattern of proliferating round and uniform tubules lined by regular epithelial cells surrounded by myoepithelial cells, packed in a small amount of stroma, highlighted by CD34 immunostaining. Tubular adenoma is a rare breast benign neoplasm of young premenopausal women. The radiologic aspects are often worrisome and only the histopathologic analysis can achieve the correct definitive diagnosis by excluding all potential differential diagnoses.

AB - Several properties of the probiotic medicinal yeast Saccharomyces boulardii CNCM I-745 contribute to its efficacy to prevent or treat diarrhoea. Besides immunologic effects, pathogen-binding and anti-toxin effects, as well as positive effects on the microbiota, S boulardii CNCM I-745 also has pronounced effects on digestive enzymes of the brush border membrane, known as trophic effects. The latter are the focus of this review. Literature has been reviewed after searching Medline and PMC databases. All relevant non-clinical and clinical studies are summarized. S. boulardii CNCM I-745 synthesizes and secretes polyamines, which have a role in cell proliferation and differentiation. The administration of polyamines or S. boulardii CNCM I-745 enhances the expression of intestinal digestive enzymes as well as nutrient uptake transporters. The signalling mechanisms leading to enzyme activation are not fully understood. However, polyamines have direct nucleic acid-binding capacity with regulatory impact. S. boulardii CNCM I-745 induces signalling via the mitogen-activated protein kinase pathway. In addition, effects on the phosphatidylinositol-3 kinase (PI3K) pathway have been reported. As an additional direct effect, S. boulardii CNCM I-745 secretes certain enzymes, which enhance nutrient acquisition for the yeast and the host. The increased availability of digestive enzymes seems to be one of the mechanisms by which S. boulardii CNCM I-745 counteracts diarrhoea; however, also people with certain enzyme deficiencies may profit from its administration. More studies are needed to fully understand the mechanisms of trophic activation by the probiotic yeast. PMID- 29449781 TI - Whole genome sequencing of multidrug-resistant Salmonella enterica serovar Typhimurium isolated from humans and poultry in Burkina Faso. AB - Background: Multidrug-resistant Salmonella is an important cause of morbidity and mortality in developing countries. The aim of this study was to characterize and compare multidrug-resistant Salmonella enterica serovar Typhimurium isolates from patients and poultry feces. Methods: Salmonella strains were isolated from poultry and patients using standard bacteriological methods described in previous studies. The strains were serotype according to Kaufmann-White scheme and tested for antibiotic susceptibility to 12 different antimicrobial agents using the disk diffusion method. The whole genome of the S. Typhimurium isolates was analyzed using Illumina technology and compared with 20 isolates of S. Typhimurium for which the ST has been deposited in a global MLST database.The ResFinder Web server was used to find the antibiotic resistance genes from whole genome sequencing (WGS) data. For comparative genomics, publicly available complete and draft genomes of different S. Typhimurium laboratory-adapted strains were downloaded from GenBank. Results: All the tested Salmonella serotype Typhimurium were multiresistant to five commonly used antibiotics (ampicillin, chloramphenicol, streptomycin, sulfonamide, and trimethoprim). The multilocus sequence type ST313 was detected from all the strains. Our sequences were very similar to S. Typhimurium ST313 strain D23580 isolated from a patient with invasive non-typhoid Salmonella (NTS) infection in Malawi, also located in sub Saharan Africa. The use of ResFinder web server on the whole genome of the strains showed a resistance to aminoglycoside associated with carriage of the following resistances genes: strA, strB, and aadA1; resistance to beta-lactams associated with carriage of a blaTEM-1B genes; resistance to phenicol associated with carriage of catA1 gene; resistance to sulfonamide associated with carriage of sul1 and sul2 genes; resistance to tetracycline associated with carriage of tet B gene; and resistance to trimethoprim associated to dfrA1 gene for all the isolates. Conclusion: The poultry and human isolates were genetically similar showing a potential food safety risk for consumers. Our finding of multidrug resistant S. Typhimurium ST313 in poultry feces calls for further studies to clarify the potential reservoirs of this emerging pathogen. PMID- 29449782 TI - Perception of American English vowels by sequential Spanish-English bilinguals. AB - Research on American-English (AE) vowel perception by Spanish-English bilinguals has focused on the vowels /i/-/i/ (e.g., in sheep/ship). Other AE vowel contrasts may present perceptual challenges for this population, especially those requiring both spectral and durational discrimination. We used Event-Related Potentials (ERPs), MMN (Mismatch Negativity) and P300, to index discrimination of AE vowels /alpha/-/v/ by sequential adult Spanish-English bilingual listeners compared to AE monolinguals. Listening tasks were non-attended and attended, and vowels were presented with natural and neutralized durations. Regardless of vowel duration, bilingual listeners showed no MMN to unattended sounds, and P300 responses were elicited to /alpha/ but not /v/ in the attended condition. Monolingual listeners showed pre-attentive discrimination (MMN) for /alpha/ only; while both vowels elicited P300 responses when attended. Findings suggest that Spanish-English bilinguals recruit attentional and cognitive resources enabling native-like use of both spectral and durational cues to discriminate between AE vowels /alpha/ and /v/. PMID- 29449783 TI - Conducting interactive experiments online. AB - Online labor markets provide new opportunities for behavioral research, but conducting economic experiments online raises important methodological challenges. This particularly holds for interactive designs. In this paper, we provide a methodological discussion of the similarities and differences between interactive experiments conducted in the laboratory and online. To this end, we conduct a repeated public goods experiment with and without punishment using samples from the laboratory and the online platform Amazon Mechanical Turk. We chose to replicate this experiment because it is long and logistically complex. It therefore provides a good case study for discussing the methodological and practical challenges of online interactive experimentation. We find that basic behavioral patterns of cooperation and punishment in the laboratory are replicable online. The most important challenge of online interactive experiments is participant dropout. We discuss measures for reducing dropout and show that, for our case study, dropouts are exogenous to the experiment. We conclude that data quality for interactive experiments via the Internet is adequate and reliable, making online interactive experimentation a potentially valuable complement to laboratory studies. PMID- 29449784 TI - Immaterial and monetary gifts in economic transactions: evidence from the field. AB - Reciprocation of monetary gifts is well-understood in economics. In contrast, there is little research on reciprocal behavior following immaterial gifts like compliments. We narrow this gap and investigate how employees reciprocate after receiving immaterial gifts and material gifts over time. We purchase (1) ice cream from fast food restaurants, and (2) durum doner, a common lunch snack, from independent vendors. Prior to the food's preparation, we either compliment or tip the salesperson. We find that salespersons reciprocate compliments with higher product weight than in a control treatment. Importantly, this reciprocal behavior following immaterial gifts grows over repeated transactions. Tips, in contrast, have a stronger level effect which does not change over time. PMID- 29449785 TI - A systematic review of burnout among doctors in China: a cultural perspective. AB - Background: Numerous studies around the world has already suggested that burnout among doctors is a global phenomenon. However, studies for burnout in doctors are relatively limited in Chinese communities when compared to the West. As risk factors, barriers to intervention and strategies combatting burnout in different parts of the world can vary a lot due to different social culture and healthcare system, study with a focus at doctors in China from a cultural perspective is a worthful endeavor. Methods: Systematic searches of databases were conducted for papers published in peer-reviewed journals from 2006 to 2016. Selection criteria included practicing doctors in Mainland China and publications written in English or Chinese. Keywords searched including "burnout", "doctors" and "China" in 3 electronic databases has been undergone. Traditional understanding of "work attitude" and "doctors' humanity" from ancient Chinese literature has also been retrieved. Results: Eleven full papers, including 9302 participants, were included in this review. The overall prevalence of burnout symptoms among doctors in China ranged from 66.5 to 87.8%. The review suggested that negative impact of burnout include association with anxiety symptoms and low job satisfaction at the individual doctors' level, and prone to committing medical mistakes affecting patient safety and higher turnover intention at the society/organizational level. Burnout was higher among doctors who worked over 40 h/week, working in tertiary hospitals, on younger age group within the profession (at age 30-40), and with negative individual perception to work and life. Conclusions and implications: The overall prevalence and adverse impact of burnout among doctors in China echo with the findings from Western studies. Young doctors and doctors working in tertiary hospitals are more at risk of burnout, probably related to shift of social culture related to the loss of medical humanities and a weak primary healthcare system. Potential strategies of managing burnout in Chinese doctors should therefore take consideration from the Chinese cultural perspective, with renaissance of medical humanities and strengthening the primary healthcare system in China. PMID- 29449786 TI - Impact of the introduction of an endotracheal tube attachment device on the incidence and severity of oral pressure injuries in the intensive care unit: a retrospective observational study. AB - Background: Endotracheal tube (ETT) fasteners such as the AnchorFastTM claim to assist with the prevention of oral pressure injuries in intubated patients, however evidence to support their clinical efficacy is limited. This retrospective observational study aimed to investigate the impact of the introduction of the AnchorFastTM device on the incidence of oral pressure injuries in mechanically ventilated patients. Methods: Data was collected from patient case notes and clinical incident reports for October 2010 to June 2013 (pre-AnchorFast) and July 2013 to March 2016 (post-AnchorFast). Incidence and location of oral pressure injuries associated with securing device, and compliance with institutional policies related to reducing oral pressure injuries were recorded. Results: Incidence of oral pressure injuries increased from 1.53/100 intubated patients in the pre-AnchorFast period to 3.73/100 intubated patients in the post-AnchorFast period (IRR = 2.43, 95%CI = 1.35-4.38; p = 0.003). Across both study periods, patients with an ETT secured using AnchorFastTM had significantly increased risk of oral pressure injuries (IRR = 2.03, 95%CI = 1.17-3.51; p = 0.02). There was also a significant difference in location of pressure injuries sustained with ETTs secured using cloth tapes (53.6% in corner of the mouth) vs. AnchorFastTM (75% on the lips) (p = 0.008). Among patients with oral pressure injuries, compliance with institutional policies relating to the prevention of pressure injuries was significantly greater after the introduction of the AnchorFastTM (9.1% vs 64.5%, p = 0.004). Conclusions: The incidence of oral pressure injuries increased significantly following the introduction of the AnchorFastTM device. Further research is required to establish the reasons for this observed increase to and identify ways to reduce the risk of pressure injuries with ETT securement devices. PMID- 29449787 TI - Cumulative receiver operating characteristics for analyzing interaction between tissue visfatin and clinicopathologic factors in breast cancer progression. AB - Background: Visfatin has been reported to be associated with breast cancer progression, but the interaction between the visfatin and clinicopathologic factors in breast cancer progression status requires further investigation. To address this problem, it is better to simultaneously consider multiple factors in sensitivity and specificity assays. Methods: In this study, a dataset for 105 breast cancer patients (84 disease-free and 21 progressing) were chosen. Individual and cumulative receiver operating characteristics (ROC) were used to analyze the impact of each factor along with interaction effects. Results: In individual ROC analysis, only 3 of 13 factors showed better performance for area under curve (AUC), i.e., AUC > 7 for hormone therapy (HT), tissue visfatin, and lymph node (LN) metastasis. Under our proposed scoring system, the cumulative ROC analysis provides higher AUC performance (0.746-0.886) than individual ROC analysis in predicting breast cancer progression. Considering the interaction between these factors, a minimum of six factors, including HT, tissue visfatin, LN metastasis, tumor stage, age, and tumor size, were identified as being highly interactive and associated with breast cancer progression, providing potential and optimal discriminators for predicting breast cancer progression. Conclusion: Taken together, the cumulative ROC analysis provides better prediction for breast cancer progression than individual ROC analysis. PMID- 29449789 TI - Factors associated with prescribing costs: analysis of a nationwide administrative database. AB - Objective: All health care systems in the world struggle with rising costs for drugs. We sought to explore factors impacting on prescribing costs in a nationwide database of ambulatory care in Germany. Factors identified by this research can be used for adjustment in future profiling efforts. Methods: We analysed nationwide prescription data of physicians having contractual relationships with statutory health insurance funds in 2014. Predictor and outcome variables were aggregated at the practice level. We performed analyses separately for primary care and specialties of cardiology, gastroenterology, neurology and psychiatry, pulmology as well as oncology and haematology. Bivariate robust regressions and Spearman rank correlations were computed in order to find meaningful predictors for our outcome variable prescription costs per patient. Results: Median age of patients and proportion of DDD issued were substantial predictors for prescription costs per patient in Primary Care, Cardiology, and Pulmology with explained variances between 41 and 61%. In Neurology and Psychiatry only proportion of patients with polypharmacy >= 2 quarters was a significant predictor for prescription costs per patient, explaining 20% of the variance. For gastroenterologists, oncologists and haematologists no stable models could be established. Conclusions: Any analysis of prescribing behaviour must take the degree into account to which an individual physician or practice is responsible for prescribing patients' medication. Proportion of prescriptions/DDDs is an essential confounder for future studies of drug prescribing. PMID- 29449790 TI - Financial Distress among Pacific Islanders in Southern California. AB - Pacific Islanders experience enduring and growing poverty in the United States, yet our understanding of their financial distress and needs is limited. Financial institutions, government agencies, and community-based organizations in areas with large Pacific Islander communities need better information with which to develop tailored programs, improve outreach and education, and improve economic security for these and other underserved populations. This paper describes the results from a unique in-language survey that asked detailed questions regarding the financial knowledge, status, and needs of Pacific Islanders, including poverty and wealth questions beyond those in the Census, in Los Angeles, Orange, and San Diego counties of Southern California. PMID- 29449788 TI - RRS1 gene expression involved in the progression of papillary thyroid carcinoma. AB - Background: Papillary thyroid carcinoma (PTC) is one of the most frequent malignancies of the endocrine system, whose mechanisms of pathogenesis, progression and prognosis are still far from being clearly elucidated. Despite an increasing body of evidences highlights ribosome biogenesis regulator homolog (RRS1) as a ribosome biogenesis protein in yeast and plants, little is known about human RRS1 function. Methods: Proliferation, cell cycle and apoptosis of PTC cells were assessed following the knockdown of RRS1 expression though MTT, colony formation assay, and flow cytometry. Then, transcriptome profiling was conducted to explore pathway changes after RRS1 silencing in PTC cells. Receiver operating characteristic curve and Youden's index were performed in twenty-four thyroid carcinoma samples to assess their potential clinical diagnostic value. Results: Firstly, we found that silencing RRS1 significantly reduced cell proliferation, inhibited cell cycle, and promoted apoptosis in PTC cell line. The result also showed that knock-down of RRS1 could up-regulate genes involving apoptosis and metabolism, while, down-regulate genes relative to cell proliferation and blood vessel development. Notably, the present study confirmed the diagnostic value of RRS1 for thyroid carcinoma in both children and adults. Conclusions: In conclusion, these data afford a comprehensive view of a novel function of human RRS1 by promoting cell proliferation and could be a potential indicator for papillary thyroid carcinoma. PMID- 29449791 TI - Influence of acute consumption of caffeine vs. placebo over Bia-derived measurements of body composition: a randomized, double-blind, crossover design. AB - Background: Bioelectrical impedance analysis (BIA) is often used to estimate total body water (TBW), intracellular body water (ICW), extracellular body water (ECW), and body fat percentage (BF%). A common restriction for BIA analysis is abstinence from caffeine 12-h prior to testing. However, research has yet to determine whether the consumption of caffeine influences BIA testing results. The purpose of this study was to determine if the consumption of caffeine influences BIA-derived BF% and body water values in habitual caffeine users. Methods: Twenty apparently healthy males (26.6 +/- 4.1 years) identified as habitual caffeine consumers (>= one 95 mg serving per day >= four days per week) participated in this study. Participants came to the lab on three occasions, the first visit serving as the control (CON) with no supplementation. The remaining two visits were performed in a randomized double-blind, cross-over fashion. Participants consumed 200 mg of dextrose (PLA) or caffeine (CAF) in capsule form. During each visit, seven multi-frequency BIA measurements were conducted before (PRE) and after (15-min, 30-min, 45-min, 60-min, 75-min, 90-min) consumption. Results: Repeated measures ANOVA revealed BF% for CAF was lower than the CON and PLA conditions at PRE and 15-min (p < 0.001, p = 0.004), but not statistically significant for the remaining time points (i.e., 30-, 45-, 60-, 75-, and 90-min). However, the effect size (ES) of the BF% differences were trivial. The CON, PLA, and CAF conditions had higher PRE ICW values than their associated post time points (i.e., 15-, 30-, 45-, 60-, 75-, and 90-min). Similar to BF%, ES of the mean differences for ICW were trivial. No other differences were observed. Conclusion: Caffeine consumption in habitual users produced trivial changes in TBW, ECW, ICW, or BF%. Therefore, the pre-testing guidelines for caffeine consumption may not be necessary in habitual caffeine consumers. PMID- 29449792 TI - Seric concentrations of copper, chromium, manganesum, nickel and selenium in aerobic, anaerobic and mixed professional sportsmen. AB - Background: The aim of the present study was to determine changes in serum concentrations of trace elements Cooper (Cu), Chromiun (Cr), Manganesum (Mn), Nickel (Ni) and Selenium (Se) in high-level sportsmen. Methods: Eighty professional athletes of different metabolic modalities, were recruited before the start of their training period. Thirty one sedentary participants of the same geographic area constituted the control group. Cu, Cr, Mn, Ni and Se analysis was performed by Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Results: Higher concentrations of Cr (p < 0.001), Mn (p < 0.085), and Ni (p < 0.001) were found in sportsmen in comparison to controls, inversely, Se values were lower (p < 0.001) among sportsmen. When sportsmen were classified by metabolic modalities, it was found that aerobic-anaerobic group had higher (p < 0.01) Cu concentrations than controls and the other sportsmen. The highest Cr values were found in aerobic participants. For Mn, the major levels were found in aerobic and aerobic anaerobic groups as well (p < 0.001). The lowest Se levels were found among anaerobic sportsmen (p < 0.001). Conclusion: This research showed that daily, continuum physical training induced alterations in serum essential minerals concentrations, as well as that these changes can be dependent of the exercise modality practiced. PMID- 29449794 TI - Leveraging annotation-based modeling with Jump. AB - The capability of UML profiles to serve as annotation mechanism has been recognized in both research and industry. Today's modeling tools offer profiles specific to platforms, such as Java, as they facilitate model-based engineering approaches. However, considering the large number of possible annotations in Java, manually developing the corresponding profiles would only be achievable by huge development and maintenance efforts. Thus, leveraging annotation-based modeling requires an automated approach capable of generating platform-specific profiles from Java libraries. To address this challenge, we present the fully automated transformation chain realized by Jump, thereby continuing existing mapping efforts between Java and UML by emphasizing on annotations and profiles. The evaluation of Jump shows that it scales for large Java libraries and generates profiles of equal or even improved quality compared to profiles currently used in practice. Furthermore, we demonstrate the practical value of Jump by contributing profiles that facilitate reverse engineering and forward engineering processes for the Java platform by applying it to a modernization scenario.

AB - Background: Scrub typhus is an acute and febrile infectious disease caused by the Gram-negative alpha-proteobacterium Orientia tsutsugamushi from the family Rickettsiaceae that is widely distributed in Northern, Southern and Eastern Asia. In the present study, we analysed the serum proteome of scrub typhus patients to investigate specific clinical protein patterns in an attempt to explain pathophysiology and discover potential biomarkers of infection. Methods: Serum samples were collected from three patients (before and after treatment with antibiotics) and three healthy subjects. One-dimensional sodium dodecyl sulphate polyacrylamide gel electrophoresis followed by liquid chromatography-tandem mass spectrometry was performed to identify differentially abundant proteins using quantitative proteomic approaches. Bioinformatic analysis was then performed using Ingenuity Pathway Analysis. Results: Proteomic analysis identified 236 serum proteins, of which 32 were differentially expressed in normal subjects, naive scrub typhus patients and patients treated with antibiotics. Comparative bioinformatic analysis of the identified proteins revealed up-regulation of proteins involved in immune responses, especially complement system, following infection with O. tsutsugamushi, and normal expression was largely rescued by antibiotic treatment. Conclusions: This is the first proteomic study of clinical serum samples from scrub typhus patients. Proteomic analysis identified changes in protein expression upon infection with O. tsutsugamushi and following antibiotic treatment. Our results provide valuable information for further investigation of scrub typhus therapy and diagnosis. PMID- 29449795 TI - Foundations for Streaming Model Transformations by Complex Event Processing. AB - Streaming model transformations represent a novel class of transformations to manipulate models whose elements are continuously produced or modified in high volume and with rapid rate of change. Executing streaming transformations requires efficient techniques to recognize activated transformation rules over a live model and a potentially infinite stream of events. In this paper, we propose foundations of streaming model transformations by innovatively integrating incremental model query, complex event processing (CEP) and reactive (event driven) transformation techniques. Complex event processing allows to identify relevant patterns and sequences of events over an event stream. Our approach enables event streams to include model change events which are automatically and continuously populated by incremental model queries. Furthermore, a reactive rule engine carries out transformations on identified complex event patterns. We provide an integrated domain-specific language with precise semantics for capturing complex event patterns and streaming transformations together with an execution engine, all of which is now part of the Viatra reactive transformation framework. We demonstrate the feasibility of our approach with two case studies: one in an advanced model engineering workflow; and one in the context of on-the fly gesture recognition. PMID- 29449796 TI - Formalization of the classification pattern: survey of classification modeling in information systems engineering. AB - Formalization is becoming more common in all stages of the development of information systems, as a better understanding of its benefits emerges. Classification systems are ubiquitous, no more so than in domain modeling. The classification pattern that underlies these systems provides a good case study of the move toward formalization in part because it illustrates some of the barriers to formalization, including the formal complexity of the pattern and the ontological issues surrounding the "one and the many." Powersets are a way of characterizing the (complex) formal structure of the classification pattern, and their formalization has been extensively studied in mathematics since Cantor's work in the late nineteenth century. One can use this formalization to develop a useful benchmark. There are various communities within information systems engineering (ISE) that are gradually working toward a formalization of the classification pattern. However, for most of these communities, this work is incomplete, in that they have not yet arrived at a solution with the expressiveness of the powerset benchmark. This contrasts with the early smooth adoption of powerset by other information systems communities to, for example, formalize relations. One way of understanding the varying rates of adoption is recognizing that the different communities have different historical baggage. Many conceptual modeling communities emerged from work done on database design, and this creates hurdles to the adoption of the high level of expressiveness of powersets. Another relevant factor is that these communities also often feel, particularly in the case of domain modeling, a responsibility to explain the semantics of whatever formal structures they adopt. This paper aims to make sense of the formalization of the classification pattern in ISE and surveys its history through the literature, starting from the relevant theoretical works of the mathematical literature and gradually shifting focus to the ISE literature. The literature survey follows the evolution of ISE's understanding of how to formalize the classification pattern. The various proposals are assessed using the classical example of classification; the Linnaean taxonomy formalized using powersets as a benchmark for formal expressiveness. The broad conclusion of the survey is that (1) the ISE community is currently in the early stages of the process of understanding how to formalize the classification pattern, particularly in the requirements for expressiveness exemplified by powersets, and (2) that there is an opportunity to intervene and speed up the process of adoption by clarifying this expressiveness. Given the central place that the classification pattern has in domain modeling, this intervention has the potential to lead to significant improvements. PMID- 29449797 TI - Dual deep modeling: multi-level modeling with dual potencies and its formalization in F-Logic. AB - An enterprise database contains a global, integrated, and consistent representation of a company's data. Multi-level modeling facilitates the definition and maintenance of such an integrated conceptual data model in a dynamic environment of changing data requirements of diverse applications. Multi level models transcend the traditional separation of class and object with clabjects as the central modeling primitive, which allows for a more flexible and natural representation of many real-world use cases. In deep instantiation, the number of instantiation levels of a clabject or property is indicated by a single potency. Dual deep modeling (DDM) differentiates between source potency and target potency of a property or association and supports the flexible instantiation and refinement of the property by statements connecting clabjects at different modeling levels. DDM comes with multiple generalization of clabjects, subsetting/specialization of properties, and multi-level cardinality constraints. Examples are presented using a UML-style notation for DDM together with UML class and object diagrams for the representation of two-level user views derived from the multi-level model. Syntax and semantics of DDM are formalized and implemented in F-Logic, supporting the modeler with integrity checks and rich query facilities.

AB - Quick detection of motor intentions is critical in order to minimize the time required to activate a neuroprosthesis. We propose a Markov Switching Model (MSM) to achieve quick detection of an event related desynchronization (ERD) elicited by motor imagery (MI) and recorded by electroencephalography (EEG). Conventional brain computer interfaces (BCI) rely on sliding window classifiers in order to perform online continuous classification of the rest vs. MI classes. Based on this approach, the detection of abrupt changes in the sensorimotor power suffers from an intrinsic delay caused by the necessity of computing an estimate of variance across several tenths of a second. Here we propose to avoid explicitly computing the EEG signal variance, and estimate the ERD state directly from the voltage information, in order to reduce the detection latency. This is achieved by using a model suitable in situations characterized by abrupt changes of state, the MSM. In our implementation, the model takes the form of a Gaussian observation model whose variance is governed by two latent discrete states with Markovian dynamics. Its objective is to estimate the brain state (i.e., rest vs. ERD) given the EEG voltage, spatially filtered by common spatial pattern (CSP), as observation. The two variances associated with the two latent states are calibrated using the variance of the CSP projection during rest and MI, respectively. The transition matrix of the latent states is optimized by the "quickest detection" strategy that minimizes a cost function of detection latency and false positive rate. Data collected by a dry EEG system from 50 healthy subjects, was used to assess performance and compare the MSM with several logistic regression classifiers of different sliding window lengths. As a result, the MSM achieves a significantly better tradeoff between latency, false positive and true positive rates. The proposed model could be used to achieve a more reactive and stable control of a neuroprosthesis. This is a desirable property in BCI-based neurorehabilitation, where proprioceptive feedback is provided based on the patient's brain signal. Indeed, it is hypothesized that simultaneous contingent association between brain signals and proprioceptive feedback induces superior associative learning.

Therefore, epigenetic mechanisms have been frequently attributed a central role in controlling cell fate determination. A prime example for this is the first discovered and still most studied epigenetic mark, DNA methylation, and the development of the most complex mammalian organ, the brain. Recently, the field of epigenetics has advanced significantly: new DNA modifications were discovered, epigenomic profiling became widely accessible, and methods for targeted epigenomic manipulation have been developed. Thus, it is time to challenge established models of epigenetic gene regulation. Here, we review the current state of knowledge about DNA modifications, their epigenomic distribution, and their regulatory role. We will summarize the evidence suggesting they possess crucial roles in neurogenesis and discuss whether this likely includes lineage choice regulation or rather effects on differentiation. Finally, we will attempt an outlook on how questions, which remain unresolved, could be answered soon. PMID- 29449800 TI - Robustness and Vulnerability of the Autoregulatory System That Maintains Nuclear TDP-43 Levels: A Trade-off Hypothesis for ALS Pathology Based on in Silico Data. AB - Abnormal accumulation of TAR DNA-binding protein 43 (TDP-43) in the cytoplasm and its disappearance from the nucleus are pathological features of amyotrophic lateral sclerosis and frontotemporal dementia (ALS/FTD) and are directly involved in the pathogenesis of these conditions. TDP-43 is an essential nuclear protein that readily aggregates in a concentration-dependent manner. Therefore, cells must strictly maintain an appropriate amount of nuclear TDP-43. In one relevant maintenance mechanism, TDP-43 binds to its pre-mRNA and promotes alternative splicing, resulting in mRNA degradation via nonsense-mediated mRNA decay. The level of nuclear TDP-43 is tightly regulated by these mechanisms, which control the amount of mRNA that may be translated. Based on the results of previous experiments, we developed an in silico model that mimics the intracellular dynamics of TDP-43 and examined TDP-43 metabolism under various conditions. We discovered an inherent trade-off in this mechanism between transcriptional redundancy, which maintains the robustness of TDP-43 metabolism, and vulnerability to specific interfering factors. These factors include an increased tendency of TDP-43 to aggregate, impaired nuclear-cytoplasmic TDP-43 transport, and a decreased efficiency of degrading abnormal proteins, all of which are functional abnormalities related to the gene that causes familial ALS/FTD. When these conditions continue at a certain intensity, the vulnerability of the autoregulatory machinery becomes apparent over time, and transcriptional redundancy enters a vicious cycle that ultimately results in TDP-43 pathology. The results obtained using this in silico model reveal the difference in TDP-43 metabolism between normal and disease states. Furthermore, using this model, we simulated the effect of a decrease in TDP-43 transcription and found that this decrease improved TDP-43 pathology and suppressed the abnormal propagation of TDP 43. Therefore, we propose a potential therapeutic strategy to suppress transcriptional redundancy, which is the driving force of the pathological condition caused by the specific factors described above, in patients with ALS presenting with TDP-43 pathology. An ALS animal model exhibiting TDP-43 pathology without overexpression of exogenous TDP-43 should be developed to investigate the effect of alleviating the transcriptional redundancy of TARDBP.

AB - Glycogen synthase kinase 3beta (GSK3beta) is a highly conserved serine/threonine kinase that has been implicated in both psychiatric and neurodegenerative diseases including schizophrenia, bipolar disorder, and Alzheimer's disease; therefore regulating its activity has become an important strategy for treatment of cognitive impairments in these disorders. This study examines the effects of lithium on GSK3beta and its interaction with beta-catenin and NMDA receptors within the prefrontal cortex. Lithium, a clinically relevant drug commonly prescribed as a mood stabilizer for psychiatric disorders, significantly increased levels of phosphorylated GSK3beta serine 9, an inhibitory phosphorylation site, and decreased beta-catenin ser33/37/thr41 phosphorylation in vitro, indicating GSK3beta inhibition and reduced beta-catenin degradation. GluN2A subunit levels were concurrently increased following lithium treatment. Similar alterations were also demonstrated in vivo; lithium administration increased GSK3beta serine 9 phosphorylation and GluN2A levels, suggesting a reduced GSK3beta activity and augmented GluN2A expression. Correspondingly, we observed that the amplitudes of evoked GluN2A-mediated excitatory postsynaptic currents in mPFC pyramidal neurons were significantly increased following lithium administration. Our data suggest that GSK3beta activity negatively regulates GluN2A expression, likely by mediating upstream beta-catenin phosphorylation, in prefrontal cortical neurons. Furthermore, our biochemical and electrophysiological experiments demonstrate that lithium mediates a specific increase in GluN2A subunit expression, ultimately augmenting GluN2A-mediated currents in the prefrontal cortex. PMID- 29449802 TI - SPARC and GluA1-Containing AMPA Receptors Promote Neuronal Health Following CNS Injury. AB - The proper formation and maintenance of functional synapses in the central nervous system (CNS) requires communication between neurons and astrocytes and the ability of astrocytes to release neuromodulatory molecules. Previously, we described a novel role for the astrocyte-secreted matricellular protein SPARC (Secreted Protein, Acidic and Rich in Cysteine) in regulating alpha-amino-3 hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPARs) and plasticity at developing synapses. SPARC is highly expressed by astrocytes and microglia during CNS development but its level is reduced in adulthood. Interestingly, SPARC has been shown to be upregulated in CNS injury and disease. However, the role of SPARC upregulation in these contexts is not fully understood. In this study, we investigated the effect of chronic SPARC administration on glutamate receptors on mature hippocampal neuron cultures and following CNS injury. We found that SPARC treatment increased the number of GluA1-containing AMPARs at synapses and enhanced synaptic function. Furthermore, we determined that the increase in synaptic strength induced by SPARC could be inhibited by Philanthotoxin-433, a blocker of homomeric GluA1-containing AMPARs. We then investigated the effect of SPARC treatment on neuronal health in an injury context where SPARC expression is upregulated. We found that SPARC levels are increased in astrocytes and microglia following middle cerebral artery occlusion (MCAO) in vivo and oxygen-glucose deprivation (OGD) in vitro. Remarkably, chronic pre-treatment with SPARC prevented OGD-induced loss of synaptic GluA1. Furthermore, SPARC treatment reduced neuronal death through Philanthotoxin-433 sensitive GluA1 receptors. Taken together, this study suggests a novel role for SPARC and GluA1 in promoting neuronal health and recovery following CNS damage. PMID- 29449804 TI - An Early Sensitive Period Induces Long-Lasting Plasticity in the Honeybee Nervous System. AB - The effect of early experiences on the brain during a sensitive period exerts a long-lasting influence on the mature individual. Despite behavioral and neural plasticity caused by early experiences having been reported in the honeybee Apis mellifera, the presence of a sensitive period in which associative experiences lead to pronounced modifications in the adult nervous system is still unclear. Laboratory-reared bees were fed with scented food within specific temporal windows and were assessed for memory retention, in the regulation of gene expression related to the synaptic formation and in the olfactory perception of their antennae at 17 days of age. Bees were able to retain a food-odor association acquired 5-8 days after emergence, but not before, and showed better retention than those exposed to an odor at 9-12 days. In the brain, the odor rewarded experiences that occurred at 5-8 days of age boosted the expression levels of the cell adhesion proteins neurexin 1 (Nrx1) and neuroligin 2 (Nlg2) involved in synaptic strength. At the antennae, the experiences increased the electrical response to a novel odor but not to the one experienced. Therefore, a sensitive period that induces long-lasting behavioral, functional and structural changes is found in adult honeybees. PMID- 29449805 TI - Screen Position Preference Offers a New Direction for Action Observation Research: Preliminary Findings Using TMS. AB - Action observation has been suggested to be an effective adjunct to physical practice in motor (re)learning settings. However, optimal viewing conditions for interventions are yet to be established. Single-pulse transcranial magnetic stimulation (TMS) was used to investigate the effect of two different screen positions and participants' screen position viewing preference on the amplitude of motor evoked potentials (MEPs) during observation of a ball pinch action. Twenty-four participants observed four blocked conditions that contained either a dynamic index finger-thumb ball pinch or a static hand holding a ball in a similar position on a horizontally or vertically positioned screen. TMS was delivered to the hand representation of the left primary motor cortex and MEPs were recorded from the first dorsal interosseous muscle of the right hand. Initial analysis of the normalized MEP amplitude data showed no significant differences between conditions. In a follow-up procedure, participants engaged in individual semi-structured interviews and completed a questionnaire designed to assess viewing affect and screen position viewing preference. The MEP data were subsequently split by screen position preference and re-analyzed using a 2 * 2 repeated measures ANOVA. Main effects indicated that participants who preferred the horizontal screen position (n = 16) demonstrated significantly greater MEP amplitudes during observation of the ball-pinch action compared to the static hand condition irrespective of screen position, and during the horizontal compared to the vertical screen position irrespective of video type. These results suggest that ensuring anatomical and perceptual congruency with the physical task, alongside consideration of participants' screen position viewing preferences, may be an important part of optimizing action observation interventions. PMID- 29449806 TI - Monitoring Attention in ADHD with an Easy-to-Use Electrophysiological Index. AB - Attention deficit hyperactivity disorder (ADHD) involves characteristic electroencephalographic (EEG) activity. We developed a single-channel EEG marker for attention: the Brain Engagement Index (BEI'). In this study, we evaluated the use of BEI' for distinguishing between ADHD patients and controls, and for monitoring the effect of pharmacological treatment on ADHD patients. The BEI' values of 20 ADHD patients and 10 controls were measured using a 1-min auditory oddball paradigm and a continuous performance test (CPT) task. We showed that CPT BEI' is trait-specific and separates controls from ADHD patients. At the same time, oddball BEI' is state-specific and identifies differences in attention level within the two groups of ADHD participants and controls. The oddball BEI' also associates with response to treatment, after distinguishing between treatment effect and learning/time effect. The combined use of this marker with common computerized tests holds promise for research and clinical use in ADHD. Further work is required to confirm the results of the present study. PMID- 29449803 TI - The Consequences of Preterm Birth and Chorioamnionitis on Brainstem Respiratory Centers: Implications for Neurochemical Development and Altered Functions by Inflammation and Prostaglandins. AB - Preterm birth is a major cause for neonatal morbidity and mortality, and is frequently associated with adverse neurological outcomes. The transition from intrauterine to extrauterine life at birth is particularly challenging for preterm infants. The main physiological driver for extrauterine transition is the establishment of spontaneous breathing. However, preterm infants have difficulty clearing lung liquid, have insufficient surfactant levels, and underdeveloped lungs. Further, preterm infants have an underdeveloped brainstem, resulting in reduced respiratory drive. These factors facilitate the increased requirement for respiratory support. A principal cause of preterm birth is intrauterine infection/inflammation (chorioamnionitis), and infants with chorioamnionitis have an increased risk and severity of neurological damage, but also demonstrate impaired autoresuscitation capacity and prevalent apnoeic episodes. The brainstem contains vital respiratory centers which provide the neural drive for breathing, but the impact of preterm birth and/or chorioamnionitis on this brain region is not well understood. The aim of this review is to provide an overview of the role and function of the brainstem respiratory centers, and to highlight the proposed mechanisms of how preterm birth and chorioamnionitis may affect central respiratory functions. PMID- 29449807 TI - Atrial Natriuretic Peptide Acts as a Neuroprotective Agent in in Vitro Models of Parkinson's Disease via Up-regulation of the Wnt/beta-Catenin Pathway. AB - In the last decades increasing evidence indicated a crucial role of the Wnt/beta catenin signaling in development of midbrain dopaminergic (mDA) neurons. Recently dysregulation of this pathway has been proposed as a novel pathomechanism leading to Parkinson's disease (PD) and some of the molecules participating to the signaling have been evaluated as potential therapeutic targets for PD. Atrial natriuretic peptide (ANP) is a cardiac-derived hormone having a critical role in cardiovascular homeostasis. ANP and its receptors (NPRs) are widely expressed in mammalian central nervous system (CNS) where they could be implicated in the regulation of neural development, synaptic transmission and information processing, as well as in neuroprotection. Until now, the effects of ANP in the CNS have been mainly ascribed to the binding and activation of NPRs. We have previously demonstrated that ANP affects the Wnt/beta-catenin signaling in colorectal cancer cells through a Frizzled receptor-mediated mechanism. The purpose of this study was to investigate if ANP is able to exert neuroprotective effect on two in vitro models of PD, and if this effect could be related to activation of the Wnt/beta-catenin signaling. As cellular models of DA neurons, we used the proliferating or RA-differentiated human neuroblastoma cell line SH SY5Y. In both DA neuron-like cultures, ANP is able to positively affect the Wnt/beta-catenin signaling, by inducing beta-catenin stabilization and nuclear translocation. Importantly, activation of the Wnt pathway by ANP exerts neuroprotective effect when these two cellular systems were subjected to neurotoxic insult (6-OHDA) for mimicking the neurodegeneration of PD. Our data support the relevance of exogenous ANP as an innovative therapeutic molecule for midbrain, and more in general for brain diseases for which aberrant Wnt signaling seems to be involved. PMID- 29449808 TI - Suppressive Effects of Clerodendrum volubile P Beauv. [Labiatae] Methanolic Extract and Its Fractions on Type 2 Diabetes and Its Complications. AB - Type 2 diabetes is the most prominent of all diabetes types, contributing to global morbidity and mortality. Availability and cost of treatment with little or no side effect especially in developing countries, remains a huge burden. This has led to the search of affordable alternative therapies especially from medicinal plants. In this study, the antidiabetic effect of the methanolic extract, dichloromethane (DCM), butanol (BuOH) and aqueous fractions of Clerodendrum volubile leaves were investigated in type 2 diabetic rats for their effect on glucose homeostasis, serum insulin level and hepatic biomarkers, lipid profile, pancreatic redox balance and Ca2+ levels, and beta-cell distribution and function. The DCM was further fractionated to isolate the active compounds, biochanin and 5,7,4'-trimethoxykaempferol. They were investigated for their toxicity and ADMET properties, alpha-glucosidase and angiotensin I converting enzyme (ACE) inhibitory activities in silico. There were significant (p < 0.05) decrease in blood glucose, cholesterol, LDL-C, vLDL-C, triglyceride, AST and ALT levels in all treated groups, with DCM fraction showing the best activity. All treated rats showed significantly (p < 0.05) improved anti-oxidative activities. Treatment with the DCM fraction led to significant (p < 0.05) increased serum insulin and pancreatic Ca2+ levels, as well as improved beta-cell distribution and function. DCM fraction also showed improved glucose tolerance. DCM fraction dose-dependently inhibited ACE activity. The toxicity class of the isolated compounds was predicted to be 5. They were also predicted to be potent inhibitors of cytochrome P (CYPs) 1A2, 2D6 and 3A4. They docked well with alpha-glucosidase and ACE. These results indicate the therapeutic potential of the plant against type 2 diabetes, with the DCM fraction being the most potent which may be attributed to the isolated flavones. It further suggests antihypertensive potentials of the DCM fraction. However, inhibition of CYPs by the flavones may suggest caution in usage with other prescribed drugs metabolized by these enzymes. PMID- 29449809 TI - Digging into Lipid Membrane Permeation for Cardiac Ion Channel Blocker d-Sotalol with All-Atom Simulations. AB - Interactions of drug molecules with lipid membranes play crucial role in their accessibility of cellular targets and can be an important predictor of their therapeutic and safety profiles. Very little is known about spatial localization of various drugs in the lipid bilayers, their active form (ionization state) or translocation rates and therefore potency to bind to different sites in membrane proteins. All-atom molecular simulations may help to map drug partitioning kinetics and thermodynamics, thus providing in-depth assessment of drug lipophilicity. As a proof of principle, we evaluated extensively lipid membrane partitioning of d-sotalol, well-known blocker of a cardiac potassium channel Kv11.1 encoded by the hERG gene, with reported substantial proclivity for arrhythmogenesis. We developed the positively charged (cationic) and neutral d sotalol models, compatible with the biomolecular CHARMM force field, and subjected them to all-atom molecular dynamics (MD) simulations of drug partitioning through hydrated lipid membranes, aiming to elucidate thermodynamics and kinetics of their translocation and thus putative propensities for hydrophobic and aqueous hERG access. We found that only a neutral form of d sotalol accumulates in the membrane interior and can move across the bilayer within millisecond time scale, and can be relevant to a lipophilic channel access. The computed water-membrane partitioning coefficient for this form is in good agreement with experiment. There is a large energetic barrier for a cationic form of the drug, dominant in water, to cross the membrane, resulting in slow membrane translocation kinetics. However, this form of the drug can be important for an aqueous access pathway through the intracellular gate of hERG. This route will likely occur after a neutral form of a drug crosses the membrane and subsequently re-protonates. Our study serves to demonstrate a first step toward a framework for multi-scale in silico safety pharmacology, and identifies some of the challenges that lie therein. PMID- 29449810 TI - Recent Advances in CNS P2X7 Physiology and Pharmacology: Focus on Neuropsychiatric Disorders. AB - The ATP-gated P2X7 ion channel is an abundant microglial protein in the CNS that plays an important pathological role in executing ATP-driven danger signal transduction. Emerging data has generated scientific interest and excitement around targeting the P2X7 ion channel as a potential drug target for CNS disorders. Over the past years, a wealth of data has been published on CNS P2X7 biology, in particular the role of P2X7 in microglial cells, and in vivo effects of brain-penetrant P2X7 antagonists. Likewise, significant progress has been made around the medicinal chemistry of CNS P2X7 ligands, as antagonists for in vivo target validation in models of CNS diseases, to identification of two clinical compounds (JNJ-54175446 and JNJ-55308942) and finally, discovery of P2X7 PET ligands. This review is an attempt to bring together the current understanding of P2X7 in the CNS with a focus on P2X7 as a drug target in neuropsychiatric disorders. PMID- 29449811 TI - HDAC6 Inhibition Promotes Transcription Factor EB Activation and Is Protective in Experimental Kidney Disease. AB - To contend with the deleterious effects of accumulating misfolded protein aggregates or damaged organelles cells rely on a system of quality control processes, among them the autophagy-lysosome pathway. This pathway is itself controlled by a master regulator transcription factor termed transcription factor EB (TFEB). When TFEB localizes to the cell nucleus it promotes the expression of a number of genes involved in protein clearance. Here, we set out to determine (1) whether TFEB expression is altered in chronic kidney disease (CKD); (2) whether inhibition of the cytosolic deacetylase histone deacetylase 6 (HDAC6) affects TFEB acetylation and nuclear localization; and (3) whether HDAC6 inhibition, in turn, alters the natural history of experimental CKD. TFEB mRNA and protein levels were observed to be diminished in the kidneys of humans with diabetic kidney disease, accompanied by accumulation of the protein aggregate adaptor protein p62 in tubule epithelial cells. In cultured NRK-52E cells, HDAC6 inhibition with the small molecule inhibitor Tubastatin A acetylated TFEB, increasing TFEB localization to the nucleus and attenuating cell death. In a rat model of CKD, Tubastatin A prevented the accumulation of misfolded protein aggregates in tubule epithelial cells, attenuated proteinuria progression, limited tubule cell death and diminished tubulointerstitial collagenous matrix deposition. These findings point to the common occurrence of dysregulated quality control processes in CKD and they suggest that TFEB downregulation may contribute to tubule injury in CKD. They also identify a regulatory relationship between HDAC6 and TFEB. HDAC6 inhibitors and TFEB activators both warrant further investigation as treatments for CKD. PMID- 29449812 TI - Calycosin Orchestrates Osteogenesis of Danggui Buxue Tang in Cultured Osteoblasts: Evaluating the Mechanism of Action by Omics and Chemical Knock-out Methodologies. AB - Danggui Buxue Tang (DBT), an ancient Chinese herbal decoction commonly used to mitigate menopausal osteoporosis, contains two herbs: Astragali Radix (AR) and Angelicae Sinensis Radix (ASR). The exact efficacy of individual chemical(s) within DBT, or in any herbal mixture, is hard to be revealed. Calycosin and ferulic acid have been reported to be the predominant chemicals found within DBT, and its roles in regulating osteoblastic differentiation have been proposed here. To probe the roles of calycosin and ferulic acid, these chemicals were specifically depleted from the DBT extracts. Here, calycosin-depleted DBT (DBTDeltacal) and ferulic acid-depleted DBT (DBTDeltafa), generated by semi preparative HPLC, were coupled with RNA-seq and metabolomics analyses to reveal the synergistic functions of individual chemicals within a complex herbal mixture. The expressions of osteogenic differentiation markers were significantly increased under the treatments of DBT and DBTDeltafa. The DBT-induced genes were markedly reduced in the absent of calycosin, i.e., DBTDeltacal. In cultured osteoblasts, the DBT-activated Wnt/beta-catenin and MAPK/Erk and signaling pathways were greatly affected when calycosin was depleted. By metabolomics analysis in DBT-treated osteoblasts, the profile of metabolites triggered by DBTDeltacal showed distinction to that of DBT and/or DBTDeltafa. Thus, our findings indicated that calycosin, rather than ferulic acid, could be an indispensable chemical in DBT to orchestrate multi-components of DBT in achieving maximal osteogenic properties. PMID- 29449813 TI - Non-nucleotide Agonists Triggering P2X7 Receptor Activation and Pore Formation. AB - The P2X7 receptor (P2X7R) is a ligand-gated plasma membrane ion channel belonging to the P2X receptor subfamily activated by extracellular nucleotides. General consensus holds that the physiological (and maybe the only) agonist is ATP. However, scattered evidence generated over the last several years suggests that ATP might not be the only agonist, especially at inflammatory sites. Solid data show that NAD+ covalently modifies the P2X7R of mouse T lymphocytes, thus lowering the ATP threshold for activation. Other structurally unrelated agents have been reported to activate the P2X7R via a poorly understood mechanism of action: (a) the antibiotic polymyxin B, possibly a positive allosteric P2X7R modulator, (b) the bactericidal peptide LL-37, (c) the amyloidogenic beta peptide, and (d) serum amyloid A. Some agents, such as Alu-RNA, have been suggested to activate the P2X7R acting on the intracellular N- or C-terminal domains. Mode of P2X7R activation by these non-nucleotide ligands is as yet unknown; however, these observations raise the intriguing question of how these different non-nucleotide ligands may co-operate with ATP at inflammatory or tumor sites. New information obtained from the cloning and characterization of the P2X7R from exotic mammalian species (e.g., giant panda) and data from recent patch-clamp studies are strongly accelerating our understanding of P2X7R mode of operation, and may provide hints to the mechanism of activation of P2X7R by non nucleotide ligands. PMID- 29449814 TI - Multisite Delayed Feedback for Electrical Brain Stimulation. AB - Demand-controlled deep brain stimulation (DBS) appears to be a promising approach for the treatment of Parkinson's disease (PD) as revealed by computational, pre clinical and clinical studies. Stimulation delivery is adapted to brain activity, for example, to the amount of neuronal activity considered to be abnormal. Such a closed-loop stimulation setup might help to reduce the amount of stimulation current, thereby maintaining therapeutic efficacy. In the context of the development of stimulation techniques that aim to restore desynchronized neuronal activity on a long-term basis, specific closed-loop stimulation protocols were designed computationally. These feedback techniques, e.g., pulsatile linear delayed feedback (LDF) or pulsatile nonlinear delayed feedback (NDF), were computationally developed to counteract abnormal neuronal synchronization characteristic for PD and other neurological disorders. By design, these techniques are intrinsically demand-controlled methods, where the amplitude of the stimulation signal is reduced when the desired desynchronized regime is reached. We here introduce a novel demand-controlled stimulation method, pulsatile multisite linear delayed feedback (MLDF), by employing MLDF to modulate the pulse amplitude of high-frequency (HF) DBS, in this way aiming at a specific, MLDF-related desynchronizing impact, while maintaining safety requirements with the charge-balanced HF DBS. Previously, MLDF was computationally developed for the control of spatio-temporal synchronized patterns and cluster states in neuronal populations. Here, in a physiologically motivated model network comprising neurons from subthalamic nucleus (STN) and external globus pallidus (GPe), we compare pulsatile MLDF to pulsatile LDF for the case where the smooth feedback signals are used to modulate the amplitude of charge-balanced HF DBS and suggest a modification of pulsatile MLDF which enables a pronounced desynchronizing impact. Our results may contribute to further clinical development of closed-loop DBS techniques.

AB - Insects, including those which provide vital ecosystems services as well as those which are devastating pests or disease vectors, locate their resources mainly based on olfaction. Understanding insect olfaction not only from a neurobiological but also from an ecological perspective is therefore crucial to balance insect control and conservation. However, among all sensory stimuli olfaction is particularly hard to grasp. Our chemical environment is made up of thousands of different compounds, which might again be detected by our nose in multiple ways. Due to this complexity, researchers have only recently begun to explore the chemosensory ecology of model organisms such as Drosophila, linking the tools of chemical ecology to those of neurogenetics. This cross-disciplinary approach has enabled several studies that range from single odors and their ecological relevance, via olfactory receptor genes and neuronal processing, up to the insects' behavior. We learned that the insect olfactory system employs strategies of combinatorial coding to process general odors as well as labeled lines for specific compounds that call for an immediate response. These studies opened new doors to the olfactory world in which insects feed, oviposit, and mate. PMID- 29449817 TI - Clinical Factors Associated with Brain Volume Reduction in Systemic Lupus Erythematosus Patients without Major Neuropsychiatric Manifestations. AB - The aim of the study was to find structural brain changes in systemic lupus erythematosus patients without major neuropsychiatric manifestations [non neuropsychiatric systemic lupus erythematosus (non-NPSLE)] using quantitative magnetic resonance imaging (MRI) and possible associations with clinical characteristics. 89 non-NPSLE patients with normal conventional MRI and 84 healthy controls (HCs) were recruited. The whole brain gray matter volume (GMV) and white matter volume (WMV) were calculated for each individual. We found obvious GMV and WMV reduction in the systemic lupus erythematosus (SLE) group compared with HCs. Female patients showed significant reduction of GMV and WMV compared with male patients. Patients treated with immunosuppressive agents (ISA) showed less WMV reduction than those without. Cognitive impairment was the most common subclinical neuropsychiatric manifestation and had a prevalence of 46.1%. Association between WMV reduction with cognitive impairment was found. Thus, we concluded that structural brain atrophy could happen even before occurrence of obvious neuropsychiatric signs and symptoms and was associated with subclinical symptoms such as cognitive impairment. ISA treatment might have a protective effect on the brain atrophy. Early treatment might prevent the progressive damage to the brain. More studies are needed to fully understand the complicated underlying mechanisms of brain atrophy in SLE. PMID- 29449818 TI - Is Reading Instruction Evidence-Based? Analyzing Teaching Practices Using T Patterns. AB - The main goal of this study was to analyze whether primary teachers use evidence based reading instruction for primary-grade readers. The study sample consisted of six teachers whose teaching was recorded. The observation instrument used was developed ad hoc for this study. The recording instrument used was Match Vision Studio. The data analysis was performed using SAS, GT version 2.0 E, and THEME. The results indicated that the teaching practices used most frequently and for the longest duration were: feedback (i.e., correcting the student when reading); fluency (i.e., individual and group reading, both out loud and silently, with and without intonation); literal or inference comprehension exercises (i.e., summarizing, asking questions); and use of educational resources (i.e., stories, songs, poems). Later, we conducted analyses of T-Patterns that showed the sequence of instruction in detail. We can conclude that <50% of the teaching practices used by the majority of teachers were based on the recommendations of the National Reading Panel (NRP). Only one teacher followed best practices. The same was the case for instructional time spent on the five essential components of reading, with the exception of teacher E., who dedicated 70.31% of class time implementing best practices. Teaching practices (i.e., learners' activities) designed and implemented to exercise and master alphabetic knowledge and phonological awareness skills were used less frequently in the classroom. PMID- 29449819 TI - Knowledge Is Power for Medical Assistants: Crystallized and Fluid Intelligence As Predictors of Vocational Knowledge. AB - Medical education research has focused almost entirely on the education of future physicians. In comparison, findings on other health-related occupations, such as medical assistants, are scarce. With the current study, we wanted to examine the knowledge-is-power hypothesis in a real life educational setting and add to the sparse literature on medical assistants. Acquisition of vocational knowledge in vocational education and training (VET) was examined for medical assistant students (n = 448). Differences in domain-specific vocational knowledge were predicted by crystallized and fluid intelligence in the course of VET. A multiple matrix design with 3 year-specific booklets was used for the vocational knowledge tests of the medical assistants. The unique and joint contributions of the predictors were investigated with structural equation modeling. Crystallized intelligence emerged as the strongest predictor of vocational knowledge at every stage of VET, while fluid intelligence only showed weak effects. The present results support the knowledge-is-power hypothesis, even in a broad and more naturalistic setting. This emphasizes the relevance of general knowledge for occupations, such as medical assistants, which are more focused on learning hands on skills than the acquisition of academic knowledge. PMID- 29449820 TI - Headache and Alexithymia in Children and Adolescents: What Is the Connection? AB - Background: Headache is one of the most common complaints in children and adolescents and comorbidity rates are very high and the major associated diseases are depression, anxiety, atopic disorders, sleep, and behavioral disorders. In recent years, it has been highlighted that difficulties regulating emotions such as alexithymia have also been associated with diagnosis of somatization. Methods: We carried out a mini review analyzing the relation between alexithymia and primary headache (e.g., migraine and tension type headache) in children and adolescents by synthesizing the relevant studies in the literature on PubMed, PsycINFO, and Google Scholar. Search terms were "alexithymia" combined with the "primary headache," "migraine," "tension type headache," "children," and "adolescents." Results: All analyzed studies found higher levels of alexithymia in children and adolescents with headache than control groups but there are different opinions about the relationship between headache and alexithymia. For example, some studies suggest that the association between headache and alexithymia in children may be due to an incomplete development of emotive competency or a general immature cognitive development, instead other studies found a correlation between headache symptoms, insecure attachment, and alexithymia. There seems to be also differences between children with migraine compared to those with tension type headache (TTH). Conclusion: There are some studies on adults suffering from headache or migraine and alexithymia, but there is only a moderate amount of research on pediatric age with different opinions and theories about this relationship. Further studies on children and adolescents are necessary to effectively understand this relationship and to help children to reduce headache and improve emotional consciousness. PMID- 29449816 TI - Economic and Health Predictors of National Postpartum Depression Prevalence: A Systematic Review, Meta-analysis, and Meta-Regression of 291 Studies from 56 Countries. AB - Background: Postpartum depression (PPD) poses a major global public health challenge. PPD is the most common complication associated with childbirth and exerts harmful effects on children. Although hundreds of PPD studies have been published, we lack accurate global or national PPD prevalence estimates and have no clear account of why PPD appears to vary so dramatically between nations. Accordingly, we conducted a meta-analysis to estimate the global and national prevalence of PPD and a meta-regression to identify economic, health, social, or policy factors associated with national PPD prevalence. Methods: We conducted a systematic review of all papers reporting PPD prevalence using the Edinburgh Postnatal Depression Scale. PPD prevalence and methods were extracted from each study. Random effects meta-analysis was used to estimate global and national PPD prevalence. To test for country level predictors, we drew on data from UNICEF, WHO, and the World Bank. Random effects meta-regression was used to test national predictors of PPD prevalence. Findings: 291 studies of 296284 women from 56 countries were identified. The global pooled prevalence of PPD was 17.7% (95% confidence interval: 16.6-18.8%), with significant heterogeneity across nations (Q = 16,823, p = 0.000, I2 = 98%), ranging from 3% (2-5%) in Singapore to 38% (35 41%) in Chile. Nations with significantly higher rates of income inequality (R2 = 41%), maternal mortality (R2 = 19%), infant mortality (R2 = 16%), or women of childbearing age working >=40 h a week (R2 = 31%) have higher rates of PPD. Together, these factors explain 73% of the national variation in PPD prevalence. Interpretation: The global prevalence of PPD is greater than previously thought and varies dramatically by nation. Disparities in wealth inequality and maternal child-health factors explain much of the national variation in PPD prevalence. PMID- 29449821 TI - Intentional Forgetting in Organizations: The Importance of Eliminating Retrieval Cues for Implementing New Routines. AB - To cope with the already large, and ever increasing, amount of information stored in organizational memory, "forgetting," as an important human memory process, might be transferred to the organizational context. Especially in intentionally planned change processes (e.g., change management), forgetting is an important precondition to impede the recall of obsolete routines and adapt to new strategic objectives accompanied by new organizational routines. We first comprehensively review the literature on the need for organizational forgetting and particularly on accidental vs. intentional forgetting. We discuss the current state of the art of theory and empirical evidence on forgetting from cognitive psychology in order to infer mechanisms applicable to the organizational context. In this respect, we emphasize retrieval theories and the relevance of retrieval cues important for forgetting. Subsequently, we transfer the empirical evidence that the elimination of retrieval cues leads to faster forgetting to the forgetting of organizational routines, as routines are part of organizational memory. We then propose a classification of cues (context, sensory, business process-related cues) that are relevant in the forgetting of routines, and discuss a meta-cue called the "situational strength" cue, which is relevant if cues of an old and a new routine are present simultaneously. Based on the classification as business process related cues (information, team, task, object cues), we propose mechanisms to accelerate forgetting by eliminating specific cues based on the empirical and theoretical state of the art. We conclude that in intentional organizational change processes, the elimination of cues to accelerate forgetting should be used in change management practices. PMID- 29449822 TI - Attachment Patterns and Complex Trauma in a Sample of Adults Diagnosed with Gender Dysphoria. AB - The current study investigated attachment representations and complex trauma in a sample of gender dysphoric adults. Although it has been proven that the psychological wellbeing of gender diverse persons is largely mediated by family acceptance and support, research on their relationships with parental figures is scarce. A total of 95 adults took part in the study. The attachment distribution was as follows: 27% secure, 27% insecure and 46% disorganized. Regarding early traumas, 56% experienced four or more traumatic forms. Further, gender dysphoric adults showed significantly higher levels of attachment disorganization and polyvictimisation, relative to controls. Comparisons of subgroups, defined by natal gender, showed that trans women, compared to control males, had more involving and physically and psychologically abusive fathers, and were more often separated from their mothers; trans men, relative to female controls, had more involving mothers and were more frequently separated from and neglected by their fathers. The research has several implications for treatment, clinical health psychology, family support and education. PMID- 29449823 TI - Age Differences in Age Perceptions and Developmental Transitions. AB - Is 50 considered "old"? When do we stop being considered "young"? If individuals could choose to be any age, what would it be? In a sample of 502,548 internet respondents ranging in age from 10 to 89, we examined age differences in aging perceptions (e.g., how old do you feel?) and estimates of the timing of developmental transitions (e.g., when does someone become an older adult?). We found that older adults reported older perceptions of aging (e.g., choosing to be older, feeling older, being perceived as older), but that these perceptions were increasingly younger than their current age. The age to which individuals hope to live dramatically increased after age 40. We also found that older adults placed the age at which developmental transitions occurred later in the life course. This latter effect was stronger for transitions involving middle-age and older adulthood compared to transitions involving young adulthood. The current study constitutes the largest study to date of age differences in age perceptions and developmental timing estimates and yielded novel insights into how the aging process may affect judgments about the self and others. PMID- 29449824 TI - Reduced Self-Control after 3 Months of Imprisonment; A Pilot Study. AB - Background: Prison can be characterized as an impoverished environment encouraging a sedentary lifestyle with limited autonomy and social interaction, which may negatively affect self-control and executive function. Here, we aim to study the effects of imprisonment on self-control and executive functions, and we report the change in neuropsychological outcome after 3 months of imprisonment. Materials and Methods: Participants were 37 male inmates in a remand prison in Amsterdam, Netherlands, who completed six tests of a computerized neuropsychological test battery (the Cambridge Automated Neuropsychological Test Battery) in the first week of arrival. Participants were retested after 3 months of imprisonment. Change in performance was tested using the Wilcoxon Signed-Rank test. Results: After 3 months of imprisonment, risk taking significantly increased (measured as an increase in the proportion of available points used for betting) and attention significantly deteriorated (measured as increased variability in reaction times on a sustained attention task), with large to medium effect sizes. In contrast, planning significantly improved (measured with a task analog to the Tower of London) with a medium effect size. Discussion: Our study suggests that 3 months of imprisonment in an impoverished environment may lead to reduced self-control, measured as increased risk taking and reduced attentional performance. This is a significant and societally relevant finding, as released prisoners may be less capable of living a lawful life than they were prior to their imprisonment, and may be more prone to impulsive risk-taking behavior. In other words, the impoverished environment may contribute to an enhanced risk of reoffending. PMID- 29449826 TI - A Critical Examination of Subgroup Analyses: The National Acute Spinal Cord Injury Studies and Beyond. AB - The use of high-dose methylprednisolone for acute spinal cord injury continues to be a topic of debate. This controversy largely stems from fundamental issues in statistical interpretation of trial data, most notably subgroup analyses. The purpose of this review is to discuss important examples of improper subgroup analysis and encourage better practices in future research. PMID- 29449825 TI - Technologies for Advanced Gait and Balance Assessments in People with Multiple Sclerosis. AB - Subtle gait and balance dysfunction is a precursor to loss of mobility in multiple sclerosis (MS). Biomechanical assessments using advanced gait and balance analysis technologies can identify these subtle changes and could be used to predict mobility loss early in the disease. This update critically evaluates advanced gait and balance analysis technologies and their applicability to identifying early lower limb dysfunction in people with MS. Non-wearable (motion capture systems, force platforms, and sensor-embedded walkways) and wearable (pressure and inertial sensors) biomechanical analysis systems have been developed to provide quantitative gait and balance assessments. Non-wearable systems are highly accurate, reliable and provide detailed outcomes, but require cumbersome and expensive equipment. Wearable systems provide less detail but can be used in community settings and can provide real-time feedback to patients and clinicians. Biomechanical analysis using advanced gait and balance analysis technologies can identify changes in gait and balance in early MS and consequently have the potential to significantly improve monitoring of mobility changes in MS. PMID- 29449827 TI - Sun Exposure across the Life Course Significantly Modulates Early Multiple Sclerosis Clinical Course. AB - Background: Low vitamin D and/or sun exposure have been associated with increased risk of multiple sclerosis (MS) onset. However, comparatively, few studies have prospectively examined associations between these factors and clinical course. Objectives: To evaluate the association of sun exposure parameters and vitamin D levels with conversion to MS and relapse risk in a prospectively monitored cohort of 145 participants followed after a first demyelinating event up to 5-year review (AusLong Study). Methods: Sun exposure prior to and after onset measured by annual questionnaire; ultraviolet radiation (UVR) "load" estimated by location of residence over the life course and ambient UVR levels. Serum 25-hydroxyvitamin D [25(OH)D] concentrations measured at baseline, 2/3-year, and 5-year review. MS conversion and relapse assessed by neurologist assessment and medical record review. Results: Over two-thirds (69%) of those followed to 5-year review (100/145) converted to MS, with a total of 252 relapses. Higher pre-MS onset sun exposure was associated with reduced risk of MS conversion, with internal consistency between measures and dose-response relationships. Analogous associations were also seen with risk of relapse, albeit less strong. No consistent associations were observed between postonset sun exposure and clinical course, however. Notably, those who increased their sun exposure during follow-up had significantly reduced hazards of MS conversion and relapse. Serum 25(OH)D levels and vitamin D supplementation were not associated with conversion to MS or relapse hazard. Conclusion: We found that preonset sun exposure was protective against subsequent conversion to MS and relapses. While consistent associations between postonset sun exposure or serum 25(OH)D level and clinical course were not evident, possibly masked by behavior change, those participants who markedly increased their sun exposure demonstrated a reduced MS conversion and relapse hazard, suggesting beneficial effects of sun exposure on clinical course. PMID- 29449829 TI - Effects of Vitamin D Deficiency on Incidence Risk of Gestational Diabetes Mellitus: A Systematic Review and Meta-analysis. AB - Introduction: Proper nutrition is important for overall health, and it reduces healthcare costs associated with malnutrition. Many studies have investigated vitamin D deficiency and its role in gestational diabetes and controversial data have reported. A comprehensive consideration of articles in this field provides the possibility of a general study of this relationship. This meta-analysis is an evaluation of the relationship between vitamin D deficiency and gestational diabetes. Material and methods: Different databases (such as PubMed, Science Information Institute, EmBase, Scopus, and the Cochrane Library) were searched for studies and eligible English articles published before February 2017 that have reported the risk of gestational diabetes in relation to vitamin D deficiency. This relationship was measured using odds ratios (ORs) with a confidence interval (CI) of 95%. The influence of each study was measured through sensitivity analysis. Funnel plots, Egger regression tests, and the Begg-Mazumdar correlation test were used to determine bias or publication bias. STATA (version 11.2) was used for all analyses. Results: Twenty-six studies were selected as eligible for this research and included in the final analysis. In general, vitamin D deficiency among mothers may be related to an increased risk of gestational diabetes (OR = 1.18; 95% CI, 1.01-1.35; p < 0.001). The serum level of 25(OH)D is less meaningful in people with gestational diabetes than in those who have normal glucose tolerance. Subgroup analysis showed that the results concerning this association may vary with study design but do not change with country of origin. Conclusion: Some evidence has shown that vitamin D deficiency may increase the risk of gestational diabetes. PMID- 29449828 TI - Understanding Spreading Depression from Headache to Sudden Unexpected Death. AB - Spreading depression (SD) is a neurophysiological phenomenon characterized by abrupt changes in intracellular ion gradients and sustained depolarization of neurons. It leads to loss of electrical activity, changes in the synaptic architecture, and an altered vascular response. Although SD is often described as a unique phenomenon with homogeneous characteristics, it may be strongly affected by the particular triggering event and by genetic background. Furthermore, SD may contribute differently to the pathogenesis of widely heterogeneous clinical conditions. Indeed, clinical disorders related to SD vary in their presentation and severity, ranging from benign headache conditions (migraine syndromes) to severely disabling events, such as cerebral ischemia, or even death in people with epilepsy. Although the characteristics and mechanisms of SD have been dissected using a variety of approaches, ranging from cells to human models, this phenomenon remains only partially understood because of its complexity and the difficulty of obtaining direct experimental data. Currently, clinical monitoring of SD is limited to patients who require neurosurgical interventions and the placement of subdural electrode strips. Significantly, SD events recorded in humans display electrophysiological features that are essentially the same as those observed in animal models. Further research using existing and new experimental models of SD may allow a better understanding of its core mechanisms, and of their differences in different clinical conditions, fostering opportunities to identify and develop targeted therapies for SD-related disorders and their worst consequences. PMID- 29449830 TI - Screening for PPAR Non-Agonist Ligands Followed by Characterization of a Hit, AM 879, with Additional No-Adipogenic and cdk5-Mediated Phosphorylation Inhibition Properties. AB - Peroxisome proliferator-activated receptor gamma (PPARgamma) is a member of a nuclear receptor superfamily and acts as a ligand-dependent transcription factor, playing key roles in maintenance of adipose tissue and in regulation of glucose and lipid homeostasis. This receptor is the target of thiazolidinediones, a class of antidiabetic drugs, which improve insulin sensitization and regulate glycemia in type 2 diabetes. Despite the beneficial effects of drugs, such as rosiglitazone and pioglitazone, their use is associated with several side effects, including weight gain, heart failure, and liver disease, since these drugs induce full activation of the receptor. By contrast, a promising activation independent mechanism that involves the inhibition of cyclin-dependent kinase 5 (CDK5)-mediated PPARgamma phosphorylation has been related to the insulin sensitizing effects induced by these drugs. Thus, we aimed to identify novel PPARgamma ligands that do not possess agonist properties by conducting a mini trial with 80 compounds using the sequential steps of thermal shift assay, 8 anilino-1-naphthalenesulfonic acid fluorescence quenching, and a cell-based transactivation assay. We identified two non-agonist PPARgamma ligands, AM-879 and P11, and one partial-agonist, R32. Using fluorescence anisotropy, we show that AM-879 does not dissociate the NCOR corepressor in vitro, and it has only a small effect on TRAP coactivator recruitment. In cells, AM-879 could not induce adipocyte differentiation or positively regulate the expression of genes associated with adipogenesis. In addition, AM-879 inhibited CDK5-mediated phosphorylation of PPARgamma in vitro. Taken together, these findings supported an interaction between AM-879 and PPARgamma; this interaction was identified by the analysis of the crystal structure of the PPARgamma:AM-879 complex and evidenced by AM-879's mechanism of action as a putative PPARgamma non-agonist with antidiabetic properties. Moreover, we present an optimized assay pipeline capable of detecting ligands that physically bind to PPARgamma but do not cause its activation as a new strategy to identify ligands for this nuclear receptor. PMID- 29449831 TI - Aspergillus terreus Inhibits Growth and Induces Morphological Abnormalities in Pythium aphanidermatum and Suppresses Pythium-Induced Damping-Off of Cucumber. AB - The study investigated the efficacy of two isolates of Aspergillus terreus (65P and 9F) on the growth, morphology and pathogenicity of Pythium aphanidermatum on cucumber. In vitro tests showed that the two isolates inhibited the growth of P. aphanidermatum in culture. Investigating P. aphanidermatum hyphae close to the inhibition zone showed that the hyphae showed abnormal growth and loss of internal content. Treating P. aphanidermatum with the culture filtrate (CF) of A. terreus resulted in significant rise in cellular leakage of P. aphanidermatum mycelium. Testing glucanase enzyme activity by both A. terreus isolates showed a significant increase in glucanase activity. This suggests that the cell walls of Pythium, which consist of glucan, are affected by the glucanase enzyme produced by A. terreus. In addition, Aspergillus isolates produced siderephore, which is suggested to be involved in inhibition of Pythium growth. Also, the CFs of 65P and 9F isolates significantly reduced spore production by P. aphanidermatum compared to the control (P < 0.05). In bioassay tests, the two isolates of A. terreus increased the survival rate of cucumber seedlings from 10 to 20% in the control seedlings treated with P. aphanidermatum to 38-39% when the biocontrol agents were used. No disease symptoms were observed on cucumber seedlings only treated with the isolates 65P and 9F of A. terreus. In addition, the A. terreus isolates did not have any negative effects on the growth of cucumber seedlings. This study shows that isolates of A. terreus can help suppress Pythium-induced damping-off of cucumber, which is suggested to be through the effect of A. terreus and its glucanase enzyme on P. aphanidermatum mycelium. PMID- 29449832 TI - Rhizosphere Competence and Biocontrol Effect of Pseudomonas sp. RU47 Independent from Plant Species and Soil Type at the Field Scale. AB - Biocontrol inoculants often show inconsistency in their efficacy at field scale and the reason for this remains often unclear. A high rhizosphere competence of inoculant strains is assumed to be a key factor for successful biocontrol effects as the biocontrol strain has to compete with the indigenous microbial community in the rhizosphere. It is known that many factors, among them plant species and soil type shape the rhizosphere microbial community composition. However, microbial community composition in the rhizosphere can also be influenced by the presence of a pathogen. We hypothesized that plant species, soil type, and a pathogen affect the rhizosphere competence of a biocontrol strain and its biocontrol effect against a soil-borne pathogen. To test the hypothesis, we used an experimental plot system with three soil types (diluvial sand, alluvial loam, loess loam) kept under similar agricultural management at the same field site for 12 years. We investigate the rhizosphere competence of Pseudomonas sp. RU47 in two plant species (potato and lettuce) and its biocontrol effect against Rhizoctonia diseases. The colonization density of a rifampicin resistant mutant of RU47 in the rhizosphere of both crops was evaluated by plate counts. Bacterial community compositions were analyzed by denaturing gradient gel electrophoresis (DGGE) of 16S rRNA gene fragments amplified from total community DNA. The inoculant RU47 was able to colonize the rhizosphere of both model crops in a sufficient density and to reduce disease severity of black scurf on potato and bottom rot on lettuce in all three soils. DGGE indicated that RU47 affected the bacterial community composition stronger in the rhizosphere of lettuce than in the potato rhizosphere. In contrast, the effect of the pathogen Rhizoctonia solani on the bacterial community was much stronger in the rhizosphere of potato than in the lettuce rhizosphere. A significant effect of RU47 on the Pseudomonas specific gacA fingerprints of the rhizosphere was only observed in lettuce in alluvial soil. The soil type and plant species independent biocontrol effects of RU47 and its minor influence on the indigenous bacterial community composition might be important criteria for the registration and use of RU47 as biocontrol strain. PMID- 29449833 TI - Stem-Loop RNA Hairpins in Giant Viruses: Invading rRNA-Like Repeats and a Template Free RNA. AB - We examine the hypothesis that de novo template-free RNAs still form spontaneously, as they did at the origins of life, invade modern genomes, contribute new genetic material. Previously, analyses of RNA secondary structures suggested that some RNAs resembling ancestral (t)RNAs formed recently de novo, other parasitic sequences cluster with rRNAs. Here positive control analyses of additional RNA secondary structures confirm ancestral and de novo statuses of RNA grouped according to secondary structure. Viroids with branched stems resemble de novo RNAs, rod-shaped viroids resemble rRNA secondary structures, independently of GC contents. 5' UTR leading regions of West Nile and Dengue flavivirid viruses resemble de novo and rRNA structures, respectively. An RNA homologous with Megavirus, Dengue and West Nile genomes, copperhead snake microsatellites and levant cotton repeats, not templated by Mimivirus' genome, persists throughout Mimivirus' infection. Its secondary structure clusters with candidate de novo RNAs. The saltatory phyletic distribution and secondary structure of Mimivirus' peculiar RNA suggest occasional template-free polymerization of this sequence, rather than noncanonical transcriptions (swinger polymerization, posttranscriptional editing). PMID- 29449834 TI - Peptidoglycan Recognition Protein 3 Does Not Alter the Outcome of Pneumococcal Pneumonia in Mice. AB - Pneumococci frequently cause community-acquired pneumonia, a disease with high mortality rates, particularly in young children and in the elderly. Endogenous antimicrobial peptides and proteins such as PGLYRP3 may contribute to the progression and outcome of this disease. Since increasing antibiotic resistant strains occur all over the world, these endogenous antimicrobial molecules are interesting new targets for future therapies. In this study, the expression pattern of PGLYRP3 was analyzed in alveolar epithelial cells, alveolar macrophages and neutrophils. Additionally, the function of PGLYRP3 during Streptococcus pneumoniae-induced pneumonia was investigated in a murine pneumococcal pneumonia model using PGLYRP3KO mice. PGLYRP3 is expressed in all selected cell types but pneumococcus-dependent induction of PGLYRP3 was observed only in neutrophils and alveolar macrophages. Interestingly, there were no significant differences in the bacterial loads within the lungs, the blood or the spleens, in the cytokine response, the composition of immune cells and the histopathology between wild type and PGLYRP3KO mice. Finally, we could neither observe significant differences in the clinical symptoms nor in the overall survival. Collectively, PGLYRP3 seems to be dispensable for the antibacterial defense during pneumococcal pneumonia. PMID- 29449835 TI - ComX-Induced Exoproteases Degrade ComX in Bacillus subtilis PS-216. AB - Gram-positive bacteria use peptides as auto-inducing (AI) signals to regulate the production of extracellular enzymes (e.g., proteases). ComX is an AI peptide, mostly known for its role in the regulation of bacterial competence and surfactant production in Bacillus subtilis. These two traits are regulated accordingly to the bacterial population size, thus classifying ComX as a quorum sensing signal. ComX also indirectly regulates exoprotease production through the intermediate transcriptional regulator DegQ. We here use this peptide-based AI system (the ComQXPA system) as a model to address exoprotease regulation by ComX in biofilms. We also investigate the potential of ComX regulated proteases to degrade the ComX AI peptide. Results indicate that ComX indeed induces the expression of aprE, the gene for the major serine protease subtilisin, and stimulates overall exoprotease production in biofilms of B. subtilis PS-216 and several other B. subtilis soil isolates. We also provide evidence that these exoproteases can degrade ComX. The ComX biological activity decay is reduced in the spent media of floating biofilms with low proteolytic activity found in the comP and degQ mutants. ComX biological activity decay can be restored by the addition of subtilisin to such media. In contrast, inhibition of metalloproteases by EDTA reduces ComX biological activity decay. This suggests that both serine and metalloproteases, which are induced by ComX, are ultimately capable of degrading this signaling peptide. This work brings novel information on regulation of exoproteases in B. subtilis floating biofilms and reveals that these proteolytic enzymes degrade the AI signaling peptide ComX, which is also a major determinant of their expression in biofilms. PMID- 29449836 TI - Changes in Microbial Energy Metabolism Measured by Nanocalorimetry during Growth Phase Transitions. AB - Calorimetric measurements of the change in heat due to microbial metabolic activity convey information about the kinetics, as well as the thermodynamics, of all chemical reactions taking place in a cell. Calorimetric measurements of heat production made on bacterial cultures have recorded the energy yields of all co occurring microbial metabolic reactions, but this is a complex, composite signal that is difficult to interpret. Here we show that nanocalorimetry can be used in combination with enumeration of viable cell counts, oxygen consumption rates, cellular protein content, and thermodynamic calculations to assess catabolic rates of an isolate of Shewanella oneidensis MR-1 and infer what fraction of the chemical energy is assimilated by the culture into biomass and what fraction is dissipated in the form of heat under different limiting conditions. In particular, our results demonstrate that catabolic rates are not necessarily coupled to rates of cell division, but rather, to physiological rearrangements of S. oneidensis MR-1 upon growth phase transitions. In addition, we conclude that the heat released by growing microorganisms can be measured in order to understand the physiochemical nature of the energy transformation and dissipation associated with microbial metabolic activity in conditions approaching those found in natural systems. PMID- 29449837 TI - Cyclic-di-GMP and oprF Are Involved in the Response of Pseudomonas aeruginosa to Substrate Material Stiffness during Attachment on Polydimethylsiloxane (PDMS). AB - Recently, we reported that the stiffness of poly(dimethylsiloxane) (PDMS) affects the attachment of Pseudomonas aeruginosa, and the morphology and antibiotic susceptibility of attached cells. To further understand how P. aeruginosa responses to material stiffness during attachment, the wild-type P. aeruginosa PAO1 and several isogenic mutants were characterized for their attachment on soft and stiff PDMS. Compared to the wild-type strain, mutation of the oprF gene abolished the differences in attachment, growth, and size of attached cells between soft and stiff PDMS surfaces. These defects were rescued by genetic complementation of oprF. We also found that the wild-type P. aeruginosa PAO1 cells attached on soft (40:1) PDMS have higher level of intracellular cyclic dimeric guanosine monophosphate (c-di-GMP), a key regulator of biofilm formation, compared to those on stiff (5:1) PDMS surfaces. Consistently, the mutants of fleQ and wspF, which have similar high-level c-di-GMP as the oprF mutant, exhibited defects in response to PDMS stiffness during attachment. Collectively, the results from this study suggest that P. aeruginosa can sense the stiffness of substrate material during attachment and respond to such mechanical cues by adjusting c-di-GMP level and thus the following biofilm formation. Further understanding of the related genes and pathways will provide new insights into bacterial mechanosensing and help develop better antifouling materials. PMID- 29449838 TI - The Divergence in Bacterial Components Associated with Bactrocera dorsalis across Developmental Stages. AB - Eco-evolutionary dynamics of microbiotas at the macroscale level are largely driven by ecological variables. The diet and living environment of the oriental fruit fly, Bactrocera dorsalis, diversify during development, providing a natural system to explore convergence, divergence, and repeatability in patterns of microbiota dynamics as a function of the host diet, phylogeny, and environment. Here, we characterized the microbiotas of 47 B. dorsalis individuals from three distinct populations by 16S rRNA amplicon sequencing. A significant deviation was found within the larvae, pupae, and adults of each population. Pupae were characterized by an increased bacterial taxonomic and functional diversity. Principal components analysis showed that the microbiotas of larvae, pupae, and adults clearly separated into three clusters. Acetobacteraceae, Lactobacillaceae, and Enterobacteriaceae were the predominant families in larval and adult samples, and PICRUSt analysis indicated that phosphoglycerate mutases and transketolases were significantly enriched in larvae, while phosphoglycerate mutases, transketolases, and proteases were significantly enriched in adults, which may support the digestive function of the microbiotas in larvae and adults. The abundances of Intrasporangiaceae, Dermabacteraceae (mainly Brachybacterium) and Brevibacteriaceae (mainly Brevibacterium) were significantly higher in pupae, and the antibiotic transport system ATP-binding protein and antibiotic transport system permease protein pathways were significantly enriched there as well, indicating the defensive function of microbiotas in pupae. Overall, differences in the microbiotas of the larvae, pupae, and adults are likely to contribute to differences in nutrient assimilation and living environments. PMID- 29449839 TI - Long-term Maintenance of CD4 T Cell Memory Responses to Malaria Antigens in Malian Children Coinfected with Schistosoma haematobium. AB - Polyparasitism is common in the developing world. We have previously demonstrated that schistosomiasis-positive (SP) Malian children, aged 4-8 years, are protected from malaria compared to matched schistosomiasis-negative (SN) children. The effect of concomitant schistosomiasis upon acquisition of T cell memory is unknown. We examined antigen-specific T cell frequencies in 48 Malian children aged 4-14 to a pool of malaria blood stage antigens, and a pool of schistosomal antigens, at a time point during a malaria episode and at a convalescent time point ~6 months later, following cessation of malaria transmission. CD4+ T cell derived memory responses, defined as one or more significant cytokine (IFN-gamma, TNF-alpha, IL-2, and/or IL-17A) responses, was measured to schistoma antigens in 18/23 SP children at one or both time points, compared to 4/23 SN children (P < 0.0001). At the time of malaria infection, 12/24 SN children and 15/23 SP children (P = 0.29) stimulated with malaria antigens demonstrated memory recall as defined by CD4-derived cytokine production. This compares to 7/23 SN children and 16/23 SP children (P = 0.009) at the convalescent timepoint. 46.2% of cytokine-producing CD4+ T cells expressed a single cytokine after stimulation with malaria antigen during the malaria episode. This fell to 40.9% at follow-up with a compensatory rise of multifunctional cytokine secretion over time, a phenomenon consistent with memory maturation. The majority (53.2-59.5%) of responses derived from CD45RA-CD62L- effector memory T cells with little variation in the phenotype depending upon the time point or the study cohort. We conclude that detectable T cell memory responses can be measured against both malaria and schistosoma antigens and that the presence of Schistosoma haematobium may be associated with long-term maintenance of T memory to malaria. PMID- 29449840 TI - c-Abl-TWIST1 Epigenetically Dysregulate Inflammatory Responses during Mycobacterial Infection by Co-Regulating Bone Morphogenesis Protein and miR27a. AB - Mycobacteria propelled modulation of host responses is of considerable interest in the face of emerging drug resistance. Although it is known that Abl tyrosine kinases affect entry and persistence of mycobacteria, mechanisms that couple c Abl to proximal signaling pathways during immunity are poorly understood. Loss-of function of c-Abl through Imatinib, in a mouse model of tuberculosis or RNA interference, identified bone morphogenesis protein (BMP) signaling as its cellular target. We demonstrate that c-Abl promotes mycobacterial survival through epigenetic modification brought about by KAT5-TWIST1 at Bmp loci. c-Abl BMP signaling deregulated iNOS, aggravating the inflammatory balance. Interestingly, BMP signaling was observed to have far-reaching effects on host immunity, as it attenuated TLR3 pathway by engaging miR27a. Significantly, these events were largely mediated via WhiB3 and DosR/S/T but not SecA signaling pathway of mycobacteria. Our findings suggest molecular mechanisms of host pathways hijacked by mycobacteria and expand our understanding of c-Abl inhibitors in potentiating innate immune responses. PMID- 29449842 TI - Pan-Influenza A Protection by Prime-Boost Vaccination with Cold-Adapted Live Attenuated Influenza Vaccine in a Mouse Model. AB - Influenza virus infections continually pose a major public health threat with seasonal epidemics and sporadic pandemics worldwide. While currently licensed influenza vaccines provide only strain-specific protection, antigenic drift and shift occasionally render the viruses resistant to the host immune responses, which highlight the need for a vaccine that provides broad protection against multiple subtypes. In this study, we suggest a vaccination strategy using cold adapted, live attenuated influenza vaccines (CAIVs) to provide a broad, potent, and safe cross-protection covering antigenically distinct hemagglutinin (HA) groups 1 and 2 influenza viruses. Using a mouse model, we tested different prime boost combinations of CAIVs for their ability to induce humoral and T-cell responses, and protective efficacy against H1 and H5 (HA group 1) as well as H3 and H7 (HA group 2) influenza viruses. Notably, even in the absence of antibody mediated neutralizing activity or HA inhibitory activity in vitro, CAIVs provided a potent protection against heterologous and heterosubtypic lethal challenges in vivo. Heterologous combination of prime (H1)-boost (H5) vaccine strains showed the most potent cross-protection efficacy. In vivo depletion experiments demonstrated not only that T cells and natural killer cells contributed to the cross-protection, but also the involvement of antibody-dependent mechanisms for the cross-protection. Vaccination-induced antibodies did not enhance the infectivity of heterologous viruses, and prime vaccination did not interfere with neutralizing antibody generation by the boost vaccination, allaying vaccine safety concerns associated with heterogeneity between the vaccines and challenge strains. Our data show that CAIV-based strategy can serve as a simple but powerful option for developing a "truly" universal influenza vaccine providing pan-influenza A protection, which has not been achieved yet by other vaccine strategies. The promising results of potency, breadth, and safety demonstrated in the mouse model support further studies in higher animal models for clinical relevance.

AB - In the last few decades, our understanding of Langerhans cells (LCs) has drastically changed based on novel findings regarding the developmental origin and biological functions of these epidermis-specific resident immune cells. It has become clear that LCs not only exert pivotal roles in immune surveillance and homeostasis but also impact on pathology by either inducing tolerance or mediating inflammation. Their unique capabilities to self-renew within the epidermis, while also being able to migrate to lymph nodes in order to present antigen, place LCs in a key position to sample the local environment and decide on the appropriate cutaneous immune response. Exciting new data distinguishing LCs from Langerin+ dermal dendritic cells (DCs) on a functional and ontogenic level reveal crucial roles for LCs in trauma and various skin pathologies, which will be thoroughly discussed here. However, despite rapid progress in the field, the exact role of LCs during immune responses has not been completely elucidated. This review focuses on what mouse models that have been developed in order to enable the study of murine LCs and other Langerin-expressing DCs have taught us about LC development and function. PMID- 29449843 TI - Insights into the Structural Basis of Antibody Affinity Maturation from Next Generation Sequencing. AB - Affinity maturation is the process whereby the immune system generates antibodies of higher affinities during a response to antigen. It is unique in being the only evolutionary mechanism known to operate on a molecule in an organism's own body. Deciphering the structural mechanisms through which somatic mutations in antibody genes increase affinity is critical to understanding the evolution of immune repertoires. Next-generation sequencing (NGS) has allowed the reconstruction of antibody clonal lineages in response to viral pathogens, such as HIV-1, which was not possible in earlier studies of affinity maturation. Crystal structures of antibodies from these lineages bound to their target antigens have revealed, at the atomic level, how antibodies evolve to penetrate the glycan shield of envelope glycoproteins, and how viruses in turn evolve to escape neutralization. Collectively, structural studies of affinity maturation have shown that increased antibody affinity can arise from any one or any combination of multiple diverse mechanisms, including improved shape complementarity at the interface with antigen, increased buried surface area upon complex formation, additional interfacial polar or hydrophobic interactions, and preorganization or rigidification of the antigen-binding site.

PMID- 29449846 TI - Pemphigus-A Disease of Desmosome Dysfunction Caused by Multiple Mechanisms. AB - Pemphigus is a severe autoimmune-blistering disease of the skin and mucous membranes caused by autoantibodies reducing desmosomal adhesion between epithelial cells. Autoantibodies against the desmosomal cadherins desmogleins (Dsgs) 1 and 3 as well as desmocollin 3 were shown to be pathogenic, whereas the role of other antibodies is unclear. Dsg3 interactions can be directly reduced by specific autoantibodies. Autoantibodies also alter the activity of signaling pathways, some of which regulate cell cohesion under baseline conditions and alter the turnover of desmosomal components. These pathways include Ca2+, p38MAPK, PKC, Src, EGFR/Erk, and several others. In this review, we delineate the mechanisms relevant for pemphigus pathogenesis based on the histology and the ultrastructure of patients' lesions. We then dissect the mechanisms which can explain the ultrastructural hallmarks detectable in pemphigus patient skin. Finally, we reevaluate the concept that the spectrum of mechanisms, which induce desmosome dysfunction upon binding of pemphigus autoantibodies, finally defines the clinical phenotype.

AB - Of all the pathogen recognition receptor families, C-type lectin receptor (CLR) induced intracellular signal cascades are indispensable for the initiation and regulation of antifungal immunity. Ongoing experiments over the last decade have elicited diverse CLR functions and novel regulatory mechanisms of CLR-mediated signaling pathways. In this review, we highlight novel insights in antifungal innate and adaptive-protective immunity mediated by CLRs and discuss the potential therapeutic strategies against fungal infection based on targeting the mediators in the host immune system. PMID- 29449847 TI - Potential Epigenetic Regulation in the Germinal Center Reaction of Lymphoid Tissues in HIV/SIV Infection. AB - The production of high-affinity and broadly neutralizing antibodies plays a key role in the defense against pathogens. These antibody responses require effective germinal center (GC) reaction within anatomical niches of GCs, where follicular helper T (Tfh) cells provide cognate help to B cells for T cell-dependent antibody responses. Emerging evidences indicate that GC reaction in normal state and perhaps establishment of latent Tfh cell reservoir in HIV/SIV infection are tightly regulated by epigenetic histone modifications, which are responsible for activating or silencing chromatin. A better understanding of the mechanisms behind GC responses at cellular and molecular levels thus provides necessary knowledge for vaccination and immunotherapy. In this review, we discussed the epigenetic regulation of GC responses, especially for GC B and Tfh cell under normal state or HIV/SIV infection. PMID- 29449848 TI - A New Suite of Plasmid Vectors for Fluorescence-Based Imaging of Root Colonizing Pseudomonads. AB - In the terrestrial ecosystem, plant-microbe symbiotic associations are ecologically and economically important processes. To better understand these associations at structural and functional levels, different molecular and biochemical tools are applied. In this study, we have constructed a suite of vectors that incorporates several new elements into the rhizosphere stable, broad host vector pME6031. The new vectors are useful for studies requiring multi-color tagging and visualization of plant-associated, Gram-negative bacterial strains such as Pseudomonas plant growth promotion and biocontrol strains. A number of genetic elements, including constitutive promoters and signal peptides that target secretion to the periplasm, have been evaluated. Several next generation fluorescent proteins, namely mTurquoise2, mNeonGreen, mRuby2, DsRed-Express2 and E2-Crimson have been incorporated into the vectors for whole cell labeling or protein tagging. Secretion of mTurquoise2 and mNeonGreen into the periplasm of Pseudomonas fluorescens SBW25 has also been demonstrated, providing a vehicle for tagging proteins in the periplasmic compartment. A higher copy number version of select plasmids has been produced by introduction of a previously described repA mutation, affording an increase in protein expression levels. The utility of these plasmids for fluorescence-based imaging is demonstrated by root colonization of Solanum lycopersicum seedlings by P. fluorescens SBW25 in a hydroponic growth system. The plasmids are stably maintained during root colonization in the absence of selective pressure for more than 2 weeks. PMID- 29449849 TI - Comprehensive Cloning of Prunus mume Dormancy Associated MADS-Box Genes and Their Response in Flower Bud Development and Dormancy. AB - Dormancy Associated MADS-box genes are SVP/MADs-box members and supposed to play crucial roles in plant dormancy of perennial species. In Prunus mume, PmDAM6 has been previously identified to induce plant dormancy. In the current study, six PmDAMs were cloned in P. mume and functionally analyzed in yeast and tobacco to detect the roles of the genes paralogous to PmDAM6. The expression patterns together with sequence similarities indicate that PmDAMs are divided into two sub clades within SVP group. Moreover, PmDAMs are verified to take part in the development of different plant organs, specifically the flower buds, in some intricate patterns. Furthermore, the PmDAM proteins are found to have special functions by forming corresponding protein complex during the development of flower bud and induction of dormancy. In particular, when PmDAM1 dominating in flower bud in the warm months, the protein complexes are consisted of PmDAM1 itself or with PmDAM2. With the decrease temperatures in the following months, PmDAM6 was found to be highly expressed and gradually changed the complex structure to PmDAM6-protein complex due to strong binding tendencies with PmDAM1 and PmDAM3. Finally, the homodimers of PmDAM6 prevailed to induce the dormancy. The results obtained in the current study highlight the functions of PmDAMs in the tissue development and dormancy, which provide available suggestions for further explorations of protein-complex functions in association with bud growth and dormancy. PMID- 29449850 TI - Irrigation and Nitrogen Regimes Promote the Use of Soil Water and Nitrate Nitrogen from Deep Soil Layers by Regulating Root Growth in Wheat. AB - Unreasonably high irrigation levels and excessive nitrogen (N) supplementation are common occurrences in the North China Plain that affect winter wheat production. Therefore, a 6-yr-long stationary field experiment was conducted to investigate the effects of irrigation and N regimes on root development and their relationship with soil water and N use in different soil layers. Compared to the non-irrigated treatment (W0), a single irrigation at jointing (W1) significantly increased yield by 3.6-45.6%. With increases in water (W2, a second irrigation at flowering), grain yield was significantly improved by 14.1-45.3% compared to the W1 treatments during the drier growing seasons (2010-2011, 2012-2013, and 2015 2016). However, under sufficient pre-sowing soil moisture conditions, grain yield was not increased, and water use efficiency (WUE) decreased significantly in the W2 treatments during normal precipitation seasons (2011-2012, 2013-2014, and 2014 2015). Irrigating the soil twice inhibited root growth into the deeper soil depth profiles and thus weakened the utilization of soil water and NO3-N from the deep soil layers. N applications increased yield by 19.1-64.5%, with a corresponding increase in WUE of 66.9-83.9% compared to the no-N treatment (N0). However, there was no further increase in grain yield and the WUE response when N rates exceeded 240 and 180 kg N ha-1, respectively. A N application rate of 240 kg ha-1 facilitated root growth in the deep soil layers, which was conducive to utilization of soil water and NO3-N and also in reducing the residual NO3-N. Correlation analysis indicated that the grain yield was significantly positively correlated with soil water storage (SWS) and nitrate nitrogen accumulation (SNA) prior to sowing. Therefore, N rates of 180-240 kg ha-1 with two irrigations can reduce the risk of yield loss that occurs due to reduced precipitation during the wheat growing seasons, while under better soil moisture conditions, a single irrigation at jointing was effective and more economical. PMID- 29449851 TI - Divergent N Deficiency-Dependent Senescence and Transcriptome Response in Developmentally Old and Young Brassica napus Leaves. AB - In the spring oilseed rape (OSR) cultivar 'Mozart' grown under optimal N supply (NO) or mild N deficiency (NL) the transcriptome changes associated with progressing age until early senescence in developmentally old lower canopy leaves (leaf #4) and younger higher canopy leaves (leaf #8) were investigated. Twelve weeks old NO and NL plants appeared phenotypically and transcriptomically identical, but thereafter distinct nutrition-dependent differences in gene expression patterns in lower and upper canopy leaves emerged. In NO leaves #4 of 14-week-old compared to 13-week-old plants, ~600 genes were up- or downregulated, whereas in NL leaves #4 ~3000 genes were up- or downregulated. In contrast, in 15 week-old compared to 13-week-old upper canopy leaves #8 more genes were up- or downregulated in optimally N-supplied plants (~2000 genes) than in N-depleted plants (~750 genes). This opposing effect of N depletion on gene regulation was even more prominent among photosynthesis-related genes (PSGs). Between week 13 and 14 in leaves #4, 99 of 110 PSGs were downregulated in NL plants, but none in NO plants. In contrast, from weeks 13 to 16 in leaves #8 of NL plants only 11 PSGs were downregulated in comparison to 66 PSGs in NO plants. Different effects of N depletion in lower versus upper canopy leaves were also apparent in upregulation of autophagy genes and NAC transcription factors. More than half of the regulated NAC and WRKY transcription factor, autophagy and protease genes were specifically regulated in NL leaves #4 or NO leaves #8 and thus may contribute to differences in senescence and nutrient mobilization in these leaves. We suggest that in N-deficient plants the upper leaves retain their N resources longer than in amply fertilized plants and remobilize them only after shedding of the lower leaves. PMID- 29449852 TI - Characterization of Sugar Contents and Sucrose Metabolizing Enzymes in Developing Leaves of Hevea brasiliensis. AB - Sucrose-metabolizing enzymes in plant leaves have hitherto been investigated mainly in temperate plants, and rarely conducted in tandem with gene expression and sugar analysis. Here, we investigated the sugar content, gene expression, and the activity of sucrose-metabolizing enzymes in the leaves of Hevea brasiliensis, a tropical tree widely cultivated for natural rubber. Sucrose, fructose and glucose were the major sugars detected in Hevea leaves at four developmental stages (I to IV), with starch and quebrachitol as minor saccharides. Fructose and glucose contents increased until stage III, but decreased strongly at stage IV (mature leaves). On the other hand, sucrose increased continuously throughout leaf development. Activities of all sucrose-cleaving enzymes decreased markedly at maturation, consistent with transcript decline for most of their encoding genes. Activity of sucrose phosphate synthase (SPS) was low in spite of its high transcript levels at maturation. Hence, the high sucrose content in mature leaves was not due to increased sucrose-synthesizing activity, but more to the decline in sucrose cleavage. Gene expression and activities of sucrose-metabolizing enzymes in Hevea leaves showed striking differences compared with other plants. Unlike in most other species where vacuolar invertase predominates in sucrose cleavage in developing leaves, cytoplasmic invertase and sucrose synthase (cleavage direction) also featured prominently in Hevea. Whereas SPS is normally responsible for sucrose synthesis in plant leaves, sucrose synthase (synthesis direction) was comparable or higher than that of SPS in Hevea leaves. Mature Hevea leaves had an unusually high sucrose:starch ratio of about 11, the highest reported to date in plants. PMID- 29449853 TI - Targeted Haplotype Comparisons between South African Wheat Cultivars Appear Predictive of Pre-harvest Sprouting Tolerance. AB - Pre-harvest sprouting (PHS) has been a serious production constraint for over two decades, especially in the summer rainfall wheat production regions of South Africa. It is a complex genetic trait controlled by multiple genes, which are significantly influenced by environmental conditions. This complicates the accurate prediction of a cultivar's stability in terms of PHS tolerance. A number of reports have documented the presence of major QTL on chromosomes 3A and 4A of modern bread wheat cultivars, which confer PHS tolerance. In this study, the SSR marker haplotype combination of chromosomes 3A and 4A of former and current South African cultivars were compared with the aim to select for improved PHS tolerance levels in future cultivars. A total of 101 wheat cultivars, including a susceptible cultivar and five international tolerant sources, were used in this study. These cultivars and donors were evaluated for their PHS tolerance by making use of a rain simulator. In addition, five seeds of each entry were planted out into seedling trays and leaf material harvested for DNA isolation. A modified CTAB extraction method was used before progressing to downstream PCR applications. Eight SSR markers targeted from the well-characterized 3A and 4A QTL regions associated with PHS tolerance, were used to conduct targeted haplotype analysis. Additionally, recently published KASP SNP markers, which identify the casual SNP mutations within the TaPHS1 gene, were used to genotype the germplasm. The haplotype marker data and phenotypic PHS data were compared across all cultivars and different production regions. A relative change in observed phenotypic variation percentage was obtained per marker allele and across marker haplotype combinations when compared to the PHS susceptible cultivar, Tugela-DN. Clear favorable haplotypes, contributing 40-60% of the variation for PHS tolerance, were identified for QTL 3A and 4A. Initial analyses show haplotype data appear to be predictive of PHS tolerance status and germplasm can now be selected to improve PHS tolerance. These haplotype data are the first of its kind for PHS genotyping in South Africa. In future, this can be used as a tool to predict the possible PHS tolerance range of a new cultivar. PMID- 29449854 TI - Genome-Wide Characterization of bHLH Genes in Grape and Analysis of their Potential Relevance to Abiotic Stress Tolerance and Secondary Metabolite Biosynthesis. AB - Basic helix-loop-helix (bHLH) transcription factors are involved in many abiotic stress responses as well as flavonol and anthocyanin biosynthesis. In grapes (Vitis vinifera L.), flavonols including anthocyanins and condensed tannins are most abundant in the skins of the berries. Flavonols are important phytochemicals for viticulture and enology, but grape bHLH genes have rarely been examined. We identified 94 grape bHLH genes in a genome-wide analysis and performed Nr and GO function analyses for these genes. Phylogenetic analyses placed the genes into 15 clades, with some remaining orphans. 41 duplicate gene pairs were found in the grape bHLH gene family, and all of these duplicate gene pairs underwent purifying selection. Nine triplicate gene groups were found in the grape bHLH gene family and all of these triplicate gene groups underwent purifying selection. Twenty-two grape bHLH genes could be induced by PEG treatment and 17 grape bHLH genes could be induced by cold stress treatment including a homologous form of MYC2, VvbHLH007. Based on the GO or Nr function annotations, we found three other genes that are potentially related to anthocyanin or flavonol biosynthesis: VvbHLH003, VvbHLH007, and VvbHLH010. We also performed a cis-acting regulatory element analysis on some genes involved in flavonoid or anthocyanin biosynthesis and our results showed that most of these gene promoters contained G-box or E-box elements that could be recognized by bHLH family members. PMID- 29449855 TI - MicroRNA160 Modulates Plant Development and Heat Shock Protein Gene Expression to Mediate Heat Tolerance in Arabidopsis. AB - Global warming is causing a negative impact on plant growth and adversely impacts on crop yield. MicroRNAs (miRNAs) are critical in regulating the expression of genes involved in plant development as well as defense responses. The effects of miRNAs on heat-stressed Arabidopsis warrants further investigation. Heat stress increased the expression of miR160 and its precursors but considerably reduced that of its targets, ARF10, ARF16, and ARF17. To study the roles of miR160 during heat stress, transgenic Arabidopsis plants overexpressing miR160 precursor a (160OE) and artificial miR160 (MIM160), which mimics an inhibitor of miR160, were created. T-DNA insertion mutants of miR160 targets were also used to examine their tolerances to heat stress. Results presented that overexpressing miR160 improved seed germination and seedling survival under heat stress. The lengths of hypocotyl elongation and rachis were also longer in 160OE than the wild-type (WT) plants under heat stress. Interestingly, MIM160 plants showed worse adaption to heat. In addition, arf10, arf16, and arf17 mutants presented similar phenotypes to 160OE under heat stress to advance abilities of thermotolerance. Moreover, transcriptome and qRT-PCR analyses revealed that HSP17.6A, HSP17.6II, HSP21, and HSP70B expression levels were regulated by heat in 160OE, MIM160, arf10, arf16, and arf17 plants. Hence, miR160 altered the expression of the heat shock proteins and plant development to allow plants to survive heat stress.

AB - Double-stranded RNA (dsRNA) plays essential functions in many biological processes, including the activation of innate immune responses and RNA interference. dsRNA also represents the genetic entity of some viruses and is a hallmark of infections by positive-sense single-stranded RNA viruses. Methods for detecting dsRNA rely essentially on immunological approaches and their use is often limited to in vitro applications, although recent developments have allowed the visualization of dsRNA in vivo. Here, we report the sensitive and rapid detection of long dsRNA both in vitro and in vivo using the dsRNA binding domain of the B2 protein from Flock house virus. In vitro, we adapted the system for the detection of dsRNA either enzymatically by northwestern blotting or by direct fluorescence labeling on fixed samples. In vivo, we produced stable transgenic Nicotiana benthamiana lines allowing the visualization of dsRNA by fluorescence microscopy. Using these techniques, we were able to discriminate healthy and positive-sense single-stranded RNA virus-infected material in plants and insect cells. In N. benthamiana, our system proved to be very potent for the spatio temporal visualization of replicative RNA intermediates of a broad range of positive-sense RNA viruses, including high- vs. low-copy number viruses. PMID- 29449857 TI - Plastid Genome Comparative and Phylogenetic Analyses of the Key Genera in Fagaceae: Highlighting the Effect of Codon Composition Bias in Phylogenetic Inference. AB - Fagaceae is one of the largest and economically important taxa within Fagales. Considering the incongruence among inferences from plastid and nuclear genes in the previous Fagaceae phylogeny studies, we assess the performance of plastid phylogenomics in this complex family. We sequenced and assembled four complete plastid genomes (Fagus engleriana, Quercus spinosa, Quercus aquifolioides, and Quercus glauca) using reference-guided assembly approach. All of the other 12 published plastid genomes in Fagaceae were retrieved for genomic analyses (including repeats, sequence divergence and codon usage) and phylogenetic inference. The genomic analyses reveal that plastid genomes in Fagaceae are conserved. Comparing the phylogenetic relationships of the key genera in Fagaceae inferred from different codon positions and gene function datasets, we found that the first two codon sites dataset recovered nearly all relationships and received high support. Thus, the result suggested that codon composition bias had great influence on Fagaceae phylogenetic inference. Our study not only provides basic understanding of Fagaceae plastid genomes, but also illuminates the effectiveness of plastid phylogenomics in resolving relationships of this intractable family. PMID- 29449858 TI - Exogenous Hydrogen Peroxide Contributes to Heme Oxygenase-1 Delaying Programmed Cell Death in Isolated Aleurone Layers of Rice Subjected to Drought Stress in a cGMP-Dependent Manner. AB - Hydrogen peroxide (H2O2) is a reactive oxygen species (ROS) that plays a dual role in plant cells. Here, we discovered that drought (20% polyethylene glycol 6000, PEG)-triggered decreases of HO-1 transcript expression and HO activity. However, exogenous H2O2 contributed toward the increase in HO-1 gene expression and activity of the enzyme under drought stress. Meanwhile, the HO-1 inducer hematin could mimic the effects of the H2O2 scavengers ascorbic acid (AsA) and dimethylthiourea (DMTU) and the H2O2 synthesis inhibitor diphenyleneiodonium (DPI) for scavenging or diminishing drought-induced endogenous H2O2. Conversely, the zinc protoporphyrin IX (ZnPPIX), an HO-1-specific inhibitor, reversed the effects of hematin. We further analyzed the endogenous H2O2 levels and HO-1 transcript expression levels of aleurone layers treated with AsA, DMTU, and DPI in the presence of exogenous H2O2 under drought stress, respectively. The results showed that in aleurone layers subjected to drought stress, when the endogenous H2O2 level was inhibited, the effect of exogenous H2O2 on the induction of HO-1 was enhanced. Furthermore, exogenous H2O2-activated HO-1 effectively enhanced amylase activity. Application of 8-bromoguanosine 3',5'-cyclic guanosine monophosphate (8-Br-cGMP) (the membrane permeable cGMP analog) promoted the effect of exogenous H2O2-delayed PCD of aleurone layers in response to drought stress. More importantly, HO-1 delayed the programmed cell death (PCD) of aleurone layers by cooperating with nitric oxide (NO), and the delayed effect of NO on PCD was achieved via mediation by cGMP under drought stress. In short, in rice aleurone layers, exogenous H2O2 (as a signaling molecule) triggered HO-1 and delayed PCD via cGMP which possibly induced amylase activity under drought stress. In contrast, as a toxic by-product of cellular metabolism, the drought generated H2O2 promoted cell death. PMID- 29449859 TI - Latitudinal Patterns in European Seagrass Carbon Reserves: Influence of Seasonal Fluctuations versus Short-Term Stress and Disturbance Events. AB - Seagrass meadows form highly productive and valuable ecosystems in the marine environment. Throughout the year, seagrass meadows are exposed to abiotic and biotic variations linked to (i) seasonal fluctuations, (ii) short-term stress events such as, e.g., local nutrient enrichment, and (iii) small-scale disturbances such as, e.g., biomass removal by grazing. We hypothesized that short-term stress events and small-scale disturbances may affect seagrass chance for survival in temperate latitudes. To test this hypothesis we focused on seagrass carbon reserves in the form of starch stored seasonally in rhizomes, as these have been defined as a good indicator for winter survival. Twelve Zostera noltei meadows were monitored along a latitudinal gradient in Western Europe to firstly assess the seasonal change of their rhizomal starch content. Secondly, we tested the effects of nutrient enrichment and/or biomass removal on the corresponding starch content by using a short-term manipulative field experiment at a single latitude in the Netherlands. At the end of the growing season, we observed a weak but significant linear increase of starch content along the latitudinal gradient from south to north. This agrees with the contention that such reserves are essential for regrowth after winter, which is more severe in the north. In addition, we also observed a weak but significant positive relationship between starch content at the beginning of the growing season and past winter temperatures. This implies a lower regrowth potential after severe winters, due to diminished starch content at the beginning of the growing season. Short-term stress and disturbances may intensify these patterns, because our manipulative experiments show that when nutrient enrichment and biomass loss co occurred at the end of the growing season, Z. noltei starch content declined. In temperate zones, the capacity of seagrasses to accumulate carbon reserves is expected to determine carbon-based regrowth after winter. Therefore, processes affecting those reserves might affect seagrass resilience. With increasing human pressure on coastal systems, short- and small-scale stress events are expected to become more frequent, threatening the resilience of seagrass ecosystems, particularly at higher latitudes, where populations tend to have an annual cycle highly dependent on their storage capacity. PMID- 29449860 TI - Adaptive Genetic Divergence Despite Significant Isolation-by-Distance in Populations of Taiwan Cow-Tail Fir (Keteleeria davidiana var. formosana). AB - Double digest restriction site-associated DNA sequencing (ddRADseq) is a tool for delivering genome-wide single nucleotide polymorphism (SNP) markers for non-model organisms useful in resolving fine-scale population structure and detecting signatures of selection. This study performs population genetic analysis, based on ddRADseq data, of a coniferous species, Keteleeria davidiana var. formosana, disjunctly distributed in northern and southern Taiwan, for investigation of population adaptive divergence in response to environmental heterogeneity. A total of 13,914 SNPs were detected and used to assess genetic diversity, FST outlier detection, population genetic structure, and individual assignments of five populations (62 individuals) of K. davidiana var. formosana. Principal component analysis (PCA), individual assignments, and the neighbor-joining tree were successful in differentiating individuals between northern and southern populations of K. davidiana var. formosana, but apparent gene flow between the southern DW30 population and northern populations was also revealed. Fifteen of 23 highly differentiated SNPs identified were found to be strongly associated with environmental variables, suggesting isolation-by-environment (IBE). However, multiple matrix regression with randomization analysis revealed strong IBE as well as significant isolation-by-distance. Environmental impacts on divergence were found between populations of the North and South regions and also between the two southern neighboring populations. BLASTN annotation of the sequences flanking outlier SNPs gave significant hits for three of 23 markers that might have biological relevance to mitochondrial homeostasis involved in the survival of locally adapted lineages. Species delimitation between K. davidiana var. formosana and its ancestor, K. davidiana, was also examined (72 individuals). This study has produced highly informative population genomic data for the understanding of population attributes, such as diversity, connectivity, and adaptive divergence associated with large- and small-scale environmental heterogeneity in K. davidiana var. formosana. PMID- 29449861 TI - Application of Electrical Capacitance Method for Prediction of Plant Root Mass and Activity in Field-Grown Crops. AB - The root electrical capacitance (C R ) method is suitable for assessing root growth and activity, but soil water content (SWC) strongly influences the measurement results. This study aimed to adapt the method for field monitoring by evaluating the effect of SWC on root capacitance to ensure the comparability of C R detected at different SWC. First a pot experiment was conducted with maize and soybean to establish C R -SWC functions for the field soil. Ontogenetic changes in root activity were monitored under field conditions by simultaneously measuring C R and SWC around the roots. The C R values were normalized using SWC data and experimental C R -SWC functions to obtain C R*, the comparable indicator of root activity. The effect of arbuscular mycorrhizal fungi (AMF) inoculation on the C R* and biomass of field-grown soybean was investigated. The pot trial showed an exponential increase in C R with SWC. C R -SWC functions proved to be species-specific. C R showed strong correlation with root dry mass (R2 = 0.83 0.87). The root activity (C R*) of field-grown crops increased until flowering, then decreased during maturity. This was consistent with data obtained with other methods. AMF inoculation of soybean resulted in significantly higher C R* during the late vegetative and early flowering stages, when destructive sampling concurrently showed higher shoot biomass. The results demonstrated that the root capacitance method could be useful for time course studies on root activity under field conditions, and for comparing single-time capacitance data collected in areas with heterogeneous soil water status. PMID- 29449862 TI - Characterization of Transcription Factor Gene OsDRAP1 Conferring Drought Tolerance in Rice. AB - HIGHLIGHTS Overexpressing and RNA interfering OsDRAP1 transgenic rice plants exhibited significantly improved and reduced drought tolerance, but accompanied with negative effects on development and yield. The dehydration responsive element binding (DREBs) genes are important transcription factors which play a crucial role in plant abiotic stress tolerances. In this study, we functionally characterized a DREB2-like gene, OsDRAP1 conferring drought tolerance (DT) in rice. OsDRAP1, containing many cis-elements in its promoter region, was expressed in all organs (mainly expressed in vascular tissues) of rice, and induced by a variety of environmental stresses and plant hormones. Overexpressing OsDRAP1 transgenic plants exhibited significantly improved DT; while OsDRAP1 RNA interfering plants exhibited significantly reduced DT which also accompanied with significant negative effects on development and yield. Overexpression of OsDRAP1 has a positive impact on maintaining water balance, redox homeostasis and vascular development in transgenic rice plants under drought stress. OsDRAP1 interacted with many genes/proteins and could activate many downstream DT related genes, including important transcription factors such as OsCBSX3 to response drought stress, indicating the OsDRAP1-mediated pathways for DT involve complex genes networks. All these results provide a basis for further complete understanding of the OsDRAP1 mediated gene networks and their related phenotypic effects.

PMID- 29449864 TI - Seasonal variation in circulating group 2 innate lymphoid cells in mugwort allergic asthmatics during and outside pollen season. AB - Background: Group 2 innate lymphoid cells (ILC2s) are a newly identified cell population with the potent capability to produce Th2-type cytokines in a non antigen specific manner. Previous study demonstrated that enhanced circulating ILC2s in cat-allergic patient after experimental allergen challenge, whereas the effects of natural allergen exposure on peripheral ILC2s are still unclear. We therefore examined the variations in circulating ILC2s among asthmatic patients sensitized to different allergens in- and outside- pollen season. Methods: 10 patients sensitized to mugwort, 10 patients sensitized to house dust mites (HDM) and 12 healthy controls were recruited into this study. Blood samples were collected from the patients in- and outside- pollens season, 2-3 months apart. ILC2s (Lin-CD127+ CRTH2+) were enumerated by flow cytometry, as well as intracellular IL-5 and IL-13 expression. The levels of IL-5 and IL-13 in supernatants of Lineage- and Lineage+ cells stimulated with IL-25 and/or IL-33 in the presence of IL-2 were measured using a Milliplex human cytokine array kit. Results: An obvious seasonal increases in percentages of total and IL-13+ ILC2s were observed in patients with mugwort sensitization during natural pollen exposure, however, the percentages of peripheral ILC2s in HDM-allergic patients were not affected significantly. A positive correlation between FeNO and IL 13+ILC2s was found in patients sensitized to mugwort. A mixture of IL-33 and IL 25 induced a significant production of IL-13 and IL-5 from Lineage- cells of both mugwort-allergic and HDM-allergic asthmatics. Stimulation with IL-33 alone induced a significantly greater quantity of IL-13 by Lineage-cells from mugwort allergic asthmatic compared with that from HDM-allergic asthmatics, whereas IL-25 induced a significantly greater amount of IL-5 by the Lineage-cells from mugwort allergic asthmatic compared with that from HDM-allergic asthmatics. Conclusion: Within pollen season the frequencies and function profiles of circulating ILC2s among asthmatic children are altered dynamically, which may be closely related to the sensitized type of allergens.

AB - Background: Although alterations in the methionine metabolism cycle (MMC) have been associated with vascular complications of diabetes, there have not been consistent results about the levels of methionine and homocysteine in type 2 diabetes mellitus (T2DM). The aim of the current study was to predict changes in plasma methionine and homocysteine concentrations after simulated consumption of methionine-rich foods, following the development of a mathematical model for MMC in Zucker Diabetic Fatty (ZDF) rats, as a representative T2DM animal model. Method: The model building and simulation were performed using NONMEM(r) (ver. 7.3.0) assisted by Perl-Speaks-NONMEM (PsN, ver. 4.3.0). Model parameters were derived using first-order conditional estimation method with interactions permitted among the parameters (FOCE-INTER). NCA was conducted using Phoenix (ver. 6.4.0). For all tests, we considered a P-value < 0.05 to reflect statistical significance. Results: Our model featured seven compartments that considered all parts of the cycle by applying non-linear mixed effects model. Conversion of S-adenosyl-L-homocysteine (SAH) to homocysteine increased and the metabolism of homocysteine was reduced under diabetic conditions, and consequently homocysteine accumulated in the elimination phase.Using our model, we performed simulations to compare the changes in plasma methionine and homocysteine concentrations between ZDF and normal rats, by multiple administrations of the methionine-rich diet of 1 mmol/kg, daily for 60 days. The levels of methionine and homocysteine were elevated approximately two- and three fold, respectively, in ZDF rats, while there were no changes observed in the normal control rats. Conclusion: These results can be interpreted to mean that both methionine and homocysteine will accumulate in patients with T2DM, who regularly consume high-methionine foods. PMID- 29449869 TI - Off-label prescription of psychiatric drugs by non-psychiatrist physicians in three general hospitals in Germany. AB - Background: Off-label prescribing of psychoactive drugs is a common practice in psychiatry. Here, we sought to investigate the frequency of off-label prescribing in a population of hospitalized patients with a somatic illness who were also suffering from a psychiatric pathology. Methods: Using a prospective, observational design, we collected data from 982 hospitalized patients with a somatic illness for whom a psychiatric consultation was requested because of the presence of additional psychiatric symptoms. Data were collected at three hospitals in Germany. Demographic and clinical data, including the previous psychoactive medications and an assessment of the suitability of the previous medications, were recorded and analyzed. Results: Data on the previous psychiatric medications were available for 972 patients. In 16.6% of patients, at least one psychoactive drug had been prescribed off-label, 20.2% had received on label medication, and 63.2% had not received any psychiatric medication. Among all patients receiving psychiatric medication, 45.1% had received off-label medication. The logistic regression analysis showed a significant influence of age on the likelihood of receiving off-label medication (p = 0.018). Benzodiazepines were the most frequent off-label prescription (25.8% of off-label prescriptions), followed by atypical antipsychotics (18.2%) and low-potency antipsychotics (17.2%). Notably, 57.1% of off-label prescriptions were judged to be 'not indicated' by experienced psychiatrists. Conclusions: Our data show a high frequency of the off-label prescription of psychoactive drugs by physicians treating patients with somatic illnesses in general hospitals. Because more than half of these cases were judged to be "not indicated", these prescriptions indicate a potential risk to patients. Furthermore, the classes of drugs that were most frequently prescribed off-label, benzodiazepines and antipsychotics, both show a substantial risk profile, particularly for elderly patients. PMID- 29449867 TI - Current therapies in alleviating liver disorders and cancers with a special focus on the potential of vitamin D. AB - Background: Liver dysfunction is a topic of global concern with many advancing therapies being researched. Though vitamin D takes a center place, other therapies especially nutritional are also gaining ground. Vitamin D has gone beyond its role in skeletal disorders by showcasing its associations in other metabolic dysfunctions too. Result: Epidemiological evidences show a correlation between the status of vitamin D and different forms of cancer. Vitamin D receptors and alterations in gene expression appear decisive in the development of chronic liver disorders. Nutritional status therefore plays a significant role in avoiding the complications related to liver dysfunctions, making it mandatory in maintaining vitamin D sufficiency in the body. Therapies with omega-3 fatty acids, antioxidants, amino acids, steroids also render benefits which could be further explored. Recent research on the progression of certain forms of liver cancer using vitamin D analogs like Seocalcitol EB 1089 has shown good promise. Conclusion: The anti-inflammatory and immuno- regulatory properties of vitamin D makes its analogs, suitable candidates of better choice for the prevention and treatment of liver disorders and cancer. PMID- 29449870 TI - Validating the Demand Control Support Questionnaire among white-collar employees in Switzerland and the United States. AB - Background: The Demand Control Support Questionnaire (DCSQ) is an established self-reported tool to measure a stressful work environment. Validated German and English versions are however currently missing. The aim of this study was therefore to evaluate the psychometric properties of German and English versions of the DCSQ among white-collar employees in Switzerland and the US. Methods: This cross-sectional study was carried out on 499 employees in Switzerland and 411 in the US, respectively. The 17-item DCSQ with three scales assessed psychosocial stress at work (psychological demands, decision latitude, and social support at work). Depressive symptoms were measured by the 2-item Patient Health Questionnaire. Cronbach's alpha and item-total correlations tested the scale reliability (internal consistency). Construct validity of the questionnaire was examined using exploratory factor analysis (EFA). Logistic regressions estimated associations of each scale and job strain with depressive symptoms (criterion validity). Results: In both samples, all DCSQ scales presented satisfactory internal consistency (Cronbach's alpha >= 0.72; item-total correlations >= 0.33), and EFA showed the 17 items loading on three factors, which is in line with the theoretically assumed structure of the DCSQ construct. Moreover, all three scales as well as high job strain were significantly associated with depressive symptoms. The associations were stronger in the US sample. Conclusions: The German and the English versions of the DCSQ seem to be reliable and valid instruments to measure psychosocial stress based on the job demand-control support model in the workplace of white-collar employees in Switzerland and the US. PMID- 29449871 TI - The elastic modulus for maize stems. AB - Background: Stalk lodging is a serious challenge in the production of maize and sorghum. A comprehensive understanding of lodging will likely require accurate characterizations of the mechanical properties of such plants. One of the most important mechanical properties for structural analysis of bending is the modulus of elasticity. The purpose of this study was to measure the modulus of elasticity of dry, mature maize rind tissues using three different loading modes (bending, compression and tensile), and to determine the accuracy and reliability of each test method. Results: The three testing modes produced comparable elastic modulus values. For the sample in this study, modulus values ranged between 6 and 16 GPa. All three testing modes exhibited relatively favorable repeatability (i.e. test to-test variation of < 5%). Modulus values of internodal specimens were significantly higher than specimens consisting of both nodal and internodal tissues, indicating spatial variation in the modulus of elasticity between the nodal and internodal regions. Conclusions: Bending tests were found to be the least labor intensive method and also demonstrated the best test-to-test repeatability. This test provides a single aggregate stiffness value for an entire stalk. Compression tests were able to determine more localized (i.e., spatially dependent) modulus of elasticity values, but required additional sample preparation and test time. Finally, tensile tests provided the most focused measurements of the modulus of elasticity, but required the longest sample preparation time. PMID- 29449872 TI - Citizen crowds and experts: observer variability in image-based plant phenotyping. AB - Background: Image-based plant phenotyping has become a powerful tool in unravelling genotype-environment interactions. The utilization of image analysis and machine learning have become paramount in extracting data stemming from phenotyping experiments. Yet we rely on observer (a human expert) input to perform the phenotyping process. We assume such input to be a 'gold-standard' and use it to evaluate software and algorithms and to train learning-based algorithms. However, we should consider whether any variability among experienced and non-experienced (including plain citizens) observers exists. Here we design a study that measures such variability in an annotation task of an integer quantifiable phenotype: the leaf count. Results: We compare several experienced and non-experienced observers in annotating leaf counts in images of Arabidopsis Thaliana to measure intra- and inter-observer variability in a controlled study using specially designed annotation tools but also citizens using a distributed citizen-powered web-based platform. In the controlled study observers counted leaves by looking at top-view images, which were taken with low and high resolution optics. We assessed whether the utilization of tools specifically designed for this task can help to reduce such variability. We found that the presence of tools helps to reduce intra-observer variability, and that although intra- and inter-observer variability is present it does not have any effect on longitudinal leaf count trend statistical assessments. We compared the variability of citizen provided annotations (from the web-based platform) and found that plain citizens can provide statistically accurate leaf counts. We also compared a recent machine-learning based leaf counting algorithm and found that while close in performance it is still not within inter-observer variability. Conclusions: While expertise of the observer plays a role, if sufficient statistical power is present, a collection of non-experienced users and even citizens can be included in image-based phenotyping annotation tasks as long they are suitably designed. We hope with these findings that we can re-evaluate the expectations that we have from automated algorithms: as long as they perform within observer variability they can be considered a suitable alternative. In addition, we hope to invigorate an interest in introducing suitably designed tasks on citizen powered platforms not only to obtain useful information (for research) but to help engage the public in this societal important problem. PMID- 29449873 TI - A novel rejuvenation approach to induce endohormones and improve rhizogenesis in mature Juglans tree. AB - Background: Juglans is a difficult-to-root tree. In the present study, we successfully rejuvenated stock plants by grafting and then burying them horizontally. Results: Rooting rates of rejuvenated shoots were 98.1% 20 days after cutting. We recorded spatial and temporal variation in endogenous indole-3 acetic acid (IAA), abscisic acid (ABA), gibberellin A3 (GA3) and zeatin-riboside (ZR) under root induction. The four types of endohormones were mainly confined to the phloem sieve and companion cells (S&Cs) at the base of either rejuvenated or mature soft shoots. IAA and ABA levels were higher in rejuvenated shoots than in mature shoots, whereas the opposite was true for GA3 and ZR. During rooting induction, GA3 was the first hormone to be observed outside phloem S&Cs, followed by IAA, ABA and ZR. In rejuvenating soft shoots, IAA accumulated in the cross sectional areas of the cambium and phloem, where root primordia were evident. Conclusions: The improvement in the rooting ability that was evident after rejuvenation most likely results a transformation of the plant to a juvenile form, from elevated IAA levels in phloem S&Cs and from a promotion of all four endohormones outside phloem S&Cs, in particular, from an accumulation of IAA in the cross-sectional areas of the cambium and phloem. PMID- 29449874 TI - An efficient modified method for plant leaf lipid extraction results in improved recovery of phosphatidic acid. AB - Background: Lipidomics plays an important role in understanding plant adaptation to different stresses and improving our knowledge of the genes underlying lipid metabolism. Lipidomics involves lipid extraction, sample preparation, mass spectrometry analysis, and data interpretation. One of the practical challenges for large-scale lipidomics studies on plant leaves is the requirement of an efficient and rapid extraction method. Results: A single-extraction method with a polar solvent mixture gives results comparable to a widely used, multi-extraction method when tested on both Arabidopsis thaliana and Sorghum bicolor leaf tissue. This single-extraction method uses a mixture of 30 parts chloroform, 25 parts isopropanol, 41.5 parts methanol, and 3.5 parts water (v/v/v/v) and a 24-h extraction time. Neither inclusion of ammonium acetate nor inclusion of acetic acid increased extraction efficiency. Conclusions: The extract produced by this method can be used for analysis by mass spectrometry without a solvent evaporation step. The amount of lipid extracted, including phosphatidic acid, is comparable to widely used, more labor-intensive methods. The single-extraction protocol is less laborious, reducing the potential for human error. PMID- 29449875 TI - A robust vegetation index for remotely assessing chlorophyll content of dorsiventral leaves across several species in different seasons. AB - Background: Leaf chlorophyll content (LCC) provides valuable information about plant physiology. Most of the published chlorophyll vegetation indices at the leaf level have been based on the spectral characteristics of the adaxial leaf surface, thus, they are not appropriate for estimating LCC when both the adaxial and abaxial leaf surfaces influence the spectral reflectance. We attempted to address this challenge by measuring the spectral reflectance of the adaxial and abaxial leaf surfaces of several plant species at different growth stages using a portable field spectroradiometer. The relationships between more than 30 published reflectance indices with LCC were analyzed to determine which index estimated LCC most effectively. Additionally, since the relationships determined on one set of samples might have poor predictive performances when applied to other samples, a robust wavelength region is required to render the spectral index generally applicable, regardless of the leaf surface or plant species. Results: The Modified Datt (MDATT) index, which is the ratio of reflectance difference defined as (Rlambda3 - Rlambda1)/(Rlambda3 - Rlambda2), exhibited the strongest correlation (R2 = 0.856, RMSE = 6.872 MUg/cm2), with LCC of all the indices tested when all the leaf samples from the adaxial and abaxial surfaces were combined. The optimal wavelength regions, which were derived from the contour maps of R2 between the MDATT index and LCC for the datasets of one side or both leaf surfaces of each plant species and their intersection, indicated that the red-edge to near-infrared wavelength (723-885 nm) was optimal for lambda1, while the red-edge region (697-771 nm) was optimal for lambda2 and lambda3. In these optimal wavelength regions, when the MDATT index was used to estimate LCC, an R2 higher than 0.8 could be obtained. The correlation of the MDATT index with LCC was the same when the positions of lambda2 and lambda3 were exchanged in the index. Conclusions: MDATT is proposed as an optimal index for the remote estimation of vegetation chlorophyll content across several plant species in different growth stages when reflectance from both leaf surfaces is considered. The red-edge to near-infrared wavelength (723-885 nm) for lambda1, as well as the red-edge region (697-771 nm) for lambda2 or lambda3, are considered to be the most robust for constructing the MDATT index for estimating LCC, regardless of the leaf surface or plant species. PMID- 29449876 TI - Authenticity analyses of Rhizoma Paridis using barcoding coupled with high resolution melting (Bar-HRM) analysis to control its quality for medicinal plant product. AB - Background: Rhizoma Paridis (Chonglou) is a commonly used and precious traditional Chinese medicine. Paris polyphylla Smith var. yunnanensis (Franch.) Hand. -Mazz. and Paris polyphylla Smith var. chinensis (Franch.) Hara are the two main sources of Chonglou under the monograph of Rhizoma Paridis in Chinese Pharmacopoeia. In the local marketplace, however, this medicine is prone to be accidentally contaminated, deliberately substituted or admixed with other species that are similar to Rhizoma Paridis in shape and color. Consequently, these adulterations might compromise quality control and result in considerable health concerns for consumers. This study aims to develop a rapid and sensitive method for accurate identification of Rhizoma Paridis and its common adulterants. Methods: DNA barcoding coupled with high resolution melting analysis was applied in this research to distinguish Rhizoma Paridis from its adulteration. The internal transcribed spacer 2 (ITS2) barcode was selected for HRM analysis to produce standard melting profile of the selected species. DNA of the tested herbal medicines was isolated and their melting profiles were generated and compared with the standard melting profile of P. polyphylla var. chinensis. Results: The results indicate that the ITS2 molecular regions coupled with HRM analysis can effectively differentiate nine herbal species, including two authentic origins of Chonglou and their seven common adulterants. Ten herbal medicines labeled "Chonglou" obtained from a local market were collected and identified with our methods, and their sequence information was analyzed to validate the accuracy of HRM analysis. Conclusions: DNA barcoding coupled with HRM analysis is a accurate, reliable, rapid, cost-effective and robust tool, which could contribute to the quality control of Rhizoma Paridis in the supply chain of the natural health product industry (NHP). PMID- 29449877 TI - Internationalization of traditional Chinese medicine: current international market, internationalization challenges and prospective suggestions. AB - Through reviewing the current international market for traditional Chinese medicine (TCM), this paper identified the internationalization challenges for TCM, including unclear therapeutic material basis and mechanism, difficulty of quality control, low preparation level, registration/policy barriers, and shortage of intellectual property. To deal with these challenges, suggestions were given including: (1) product innovation of TCM (study the TCM by using the methods and means of western medicine; innovate the basic theory of TCM; develop TCM health product); (2) standard innovation of TCM; (3) building big data platform of Chinese medicine (big data platform of TCM preparation; big data platform on the quality of TCM). PMID- 29449878 TI - Complete chloroplast genome of the medicinal plant Amomum compactum: gene organization, comparative analysis, and phylogenetic relationships within Zingiberales. AB - Background: Amomum compactum is one of the basic species of the traditional herbal medicine amomi fructus rotundus, with great pharmacology effect. The system position of A. compactum is not clear yet, and the introduction of this plant has been hindered by many plant diseases. However, the correlational molecular studies are relatively scarce. Methods: The total chloroplast (cp) DNA was extracted according to previous studies, and then sequenced by 454 GS FLX Titanium platform. Sequence assembly was complished by Newbler. Genome annotation was preformed by CPGAVAS and tRNA-SCAN. Then, general characteristics of the A. compactum cp genome and genome comparsion with three Zingiberaceae species was analyzed by corresponding softwares. Additionally, phylogenetical trees were reconstructed, based on the shared protein-coding gene sequences among 15 plant taxa by maximum parsimony (MP) and maximum likelihood (ML) methods. Results: The A. compactum cp genome with a classic quadripartite structure, consisting of a pair of reverse complement repeat regions (IRa/IRb) of 29,824 bp, a large single copy (LSC, 88,535 bp) region as well as a small single copy (SSC, 15,370 bp) region, is 163,553 bp in total size. The total GC content of this cp genome is 36.0%. The A. compactum cp genome owns 135 functional genes, that 113 genes are unique, containing eighty protein-coding genes, twenty-nine tRNA (transfer RNA) genes and four rRNA (ribosomal RNA) genes. Codon usage of the A. compactum cp genome is biased toward codons ending with A/T. Total 58 SSR loci and 24 large repeats are detected in the A. compactum cp genome. Relative to three other Zingiberaceae cp genomes, the A. compactum cp genome exhibits an obvious expansion in the IR regions. In A. compactum cp genome, the ycf1 pseudogene is 2969 bp away from the IRa/SSC border, whereas in other Zingiberaceae species, it is only 4-5 bp away from the IRa/SSC border. Comparative cp genome sequences analysis of A. compactum with other Zingiberaceae reveals that the gene order and gene content differ slightly among Zingiberaceae species. The phylogenetic analysis based on 67 protein-coding gene sequences supports the phylogenetic position of A. compactum. Conclusions: The study has identified unique features of the A. compactum cp genome which would be helpful for us to understand the cp genome evolution and offer useful information for phylogenetics and further studies of this traditional medicinal plant. PMID- 29449879 TI - The impact of Cognitive Processing Therapy on stigma among survivors of sexual violence in eastern Democratic Republic of Congo: results from a cluster randomized controlled trial. AB - Background: Sexual violence is associated with a multitude of poor physical, emotional, and social outcomes. Despite reports of stigma by sexual violence survivors, limited evidence exists on effective strategies to reduce stigma, particularly in conflict-affected settings. We sought to assess the effect of group Cognitive Processing Therapy (CPT) on stigma and the extent to which stigma might moderate the effectiveness of CPT in treating mental health problems among survivors of sexual violence in the Democratic Republic of Congo. Methods: Data were drawn from 405 adult female survivors of sexual violence reporting mental distress and poor functioning in North and South Kivu. Women were recruited through organizations providing psychosocial support and then cluster randomized to group CPT or individual support. Women were assessed at baseline, the end of treatment, and again six months later. Assessors were masked to women's treatment assignment. Linear mixed-effect regression models were used to estimate (1) the effect of CPT on feelings of perceived and internalized (felt) stigma, and (2) whether felt stigma and discrimination (enacted stigma) moderated the effects of CPT on combined depression and anxiety symptoms, posttraumatic stress, and functional impairment. Results: Participants receiving CPT experienced moderate reductions in felt stigma relative to those in individual support (Cohen's D = 0.44, p = value = 0.02) following the end of treatment, though this difference was no longer significant six-months later (Cohen's D = 0.45, p = value = 0.12). Neither felt nor enacted stigma significantly moderated the effect of CPT on mental health symptoms or functional impairment. Conclusions: Group cognitive behavioral based therapies may be an effective stigma reduction tool for survivors of sexual violence. Experiences and perceptions of stigma did not hinder therapeutic effects of group psychotherapy on survivors' mental health. Trial registration: ClinicalTrials.gov NCT01385163. PMID- 29449880 TI - Characterization and engineering of a dual-function diacylglycerol acyltransferase in the oleaginous marine diatom Phaeodactylum tricornutum. AB - Background: Photosynthetic oleaginous microalgae are promising feedstocks for biofuels. Acyl-CoA:diacylglycerol acyltransferases (DGATs) represent rich sources for engineering microalgal lipid production. The principal activity of DGATs has been defined as a single-function enzyme catalyzing the esterification of diacylglycerol with acyl-CoA. Results: A dual-function PtWS/DGAT associated with diatom Phaeodactylum tricornutum is discovered in the current study. Distinctive to documented microalgal DGAT types, PtWS/DGAT exhibits activities of both a wax ester synthase (WS) and a DGAT. WS/DGATs are broadly distributed in microalgae, with different topology and phylogeny from those of DGAT1s, DGAT2s, and DGAT3s. In vitro and in vivo assays revealed that PtWS/DGAT, functioning as either a WS or a DGAT, exhibited a preference on saturated FA substrate. Endogenous overexpression of PtWS/DGAT demonstrated that the DGAT activity was dominant, whereas the WS activity was condition dependent and relatively minor. Compared with the wild type (WT), overexpression of PtWS/DGAT in the diatom resulted in increased levels of total lipids (TL) and triacylglycerol (TAG) regardless of nitrogen availability. The stability and scalability of the introduced traits were further investigated at a 10-L photobioreactor, where the mutant growth resembled WT, with moderately increased productivity of TL and TAG. Furthermore, the production of wax esters increased considerably (from undetectable levels to 2.83%) under nitrogen-deplete conditions. Conclusions: PtWS/DGAT is a bifunctional enzyme and may serve as a promising target for the engineering of microalga-based oils and waxes for future industrial use. PMID- 29449881 TI - A copper-controlled RNA interference system for reversible silencing of target genes in Trichoderma reesei. AB - Background: Trichoderma reesei is a primary lignocellulosic enzyme producer in industry. However, the mechanisms underlying cellulase synthesis as well as other physiological processes are insufficiently understood partly due to the sophisticated process for its genetic manipulation. Target gene knockdown by RNA interference (RNAi) is a powerful tool for genetic research and biotechnology in eukaryotes including filamentous fungi. Previously reported RNAi system in T. reesei was either uncontrollable or only applicable in certain nutrition state. Results: In the present study, we incorporated the copper-responsive tcu1 promoter into an RNAi-mediated silencing system to develop a controllable RNAi mediated silencing system in T. reesei. As the proof-of-concept, a prototrophic pyr4 gene, highly expressed cel7a and xyr1 genes induced by Avicel and a fab1 gene, whose knockout has proved to be intractable, were successfully knocked down in the absence of copper when the respective RNAi fragment was expressed. Importantly, the phenotype of RNAi strains was shown to be reversed easily to mimic the complementation for excluding any unwanted effects resulted from the random integration of the hpRNA cassette by adding copper in the media. Thus, this controllable RNAi-mediated silencing system can be turned on and turned off only depending on the absence and presence of copper ions in the media, respectively, and not on the nutritional states. Conclusions: The copper controlled RNA interference system represents an effective tool for reversible silencing of target genes in T. reesei. This reported strategy to conditionally knock down or turn off genes will contribute to our understanding of T. reesei gene functions, especially those that are difficult to be knocked out due to various reasons. In addition, this simple and cost-effective method holds great potential for the application in synthetic biology and genetic engineering of T. reesei. PMID- 29449882 TI - Mathematical models of lignin biosynthesis. AB - Background: Lignin is a natural polymer that is interwoven with cellulose and hemicellulose within plant cell walls. Due to this molecular arrangement, lignin is a major contributor to the recalcitrance of plant materials with respect to the extraction of sugars and their fermentation into ethanol, butanol, and other potential bioenergy crops. The lignin biosynthetic pathway is similar, but not identical in different plant species. It is in each case comprised of a moderate number of enzymatic steps, but its responses to manipulations, such as gene knock downs, are complicated by the fact that several of the key enzymes are involved in several reaction steps. This feature poses a challenge to bioenergy production, as it renders it difficult to select the most promising combinations of genetic manipulations for the optimization of lignin composition and amount. Results: Here, we present several computational models than can aid in the analysis of data characterizing lignin biosynthesis. While minimizing technical details, we focus on the questions of what types of data are particularly useful for modeling and what genuine benefits the biofuel researcher may gain from the resulting models. We demonstrate our analysis with mathematical models for black cottonwood (Populus trichocarpa), alfalfa (Medicago truncatula), switchgrass (Panicum virgatum) and the grass Brachypodium distachyon. Conclusions: Despite commonality in pathway structure, different plant species show different regulatory features and distinct spatial and topological characteristics. The putative lignin biosynthes pathway is not able to explain the plant specific laboratory data, and the necessity of plant specific modeling should be heeded. PMID- 29449883 TI - Production of (2R, 3R)-2,3-butanediol using engineered Pichia pastoris: strain construction, characterization and fermentation. AB - Background: 2,3-butanediol (2,3-BD) is a bulk platform chemical with various potential applications such as aviation fuel. 2,3-BD has three optical isomers: (2R, 3R)-, (2S, 3S)- and meso-2,3-BD. Optically pure 2,3-BD is a crucial precursor for the chiral synthesis and it can also be used as anti-freeze agent due to its low freezing point. 2,3-BD has been produced in both native and non native hosts. Several pathogenic bacteria were reported to produce 2,3-BD in mixture of its optical isomers including Klebsiella pneumoniae and Klebsiella oxytoca. Engineered hosts based on episomal plasmid expression such as Escherichia coli, Saccharomyces cerevisiae and Bacillus subtilis are not ideal for industrial fermentation due to plasmid instability. Results: Pichia pastoris is generally regarded as safe and a well-established host for high-level heterologous protein production. To produce pure (2R, 3R)-2,3-BD enantiomer, we developed a P. pastoris strain by introducing a synthetic pathway. The alsS and alsD genes from B. subtilis were codon-optimized and synthesized. The BDH1 gene from S. cerevisiae was cloned. These three pathway genes were integrated into the genome of P. pastoris and expressed under the control of GAP promoter. Production of (2R, 3R)-2,3-BD was achieved using glucose as feedstock. The optical purity of (2R, 3R)-2,3-BD was more than 99%. The titer of (2R, 3R)-2,3-BD reached 12 g/L with 40 g/L glucose as carbon source in shake flask fermentation. The fermentation conditions including pH, agitation speeds and aeration rates were optimized in batch cultivations. The highest titer of (2R, 3R)-2,3-BD achieved in fed-batch fermentation using YPD media was 45 g/L. The titer of 2,3-BD was enhanced to 74.5 g/L through statistical medium optimization. Conclusions: The potential of engineering P. pastoris into a microbial cell factory for biofuel production was evaluated in this work using (2R, 3R)-2,3-BD as an example. Engineered P. pastoris could be a promising workhorse for the production of optically pure (2R, 3R)-2,3-BD. PMID- 29449884 TI - Improved photobio-H2 production regulated by artificial miRNA targeting psbA in green microalga Chlamydomonas reinhardtii. AB - Background: Sulfur-deprived cultivation of Chlamydomonas reinhardtii, referred as "two-stage culture" transferring the cells from regular algal medium to sulfur deplete one, has been extensively studied to improve photobio-H2 production in this green microalga. During sulfur-deprivation treatment, the synthesis of a key component of photosystem II complex, D1 protein, was inhibited and improved photobio-H2 production could be established in C. reinhardtii. However, separation of algal cells from a regular liquid culture medium to a sulfur deprived one is not only a discontinuous process, but also a cost- and time consuming operation. More applicable and economic alternatives for sustained H2 production by C. reinhardtii are still highly required. Results: In the present study, a significant improvement in photobio-H2 production was observed in the transgenic green microalga C. reinhardtii, which employed a newly designed strategy based on a heat-inducible artificial miRNA (amiRNA) expression system targeting D1-encoded gene, psbA. A transgenic algal strain referred as "amiRNA D1" has been successfully obtained by transforming the expression vector containing a heat-inducible promoter. After heat shock conducted in the same algal cultures, the expression of amiRNA-D1 was detected increased 15-fold accompanied with a 73% decrease of target gene psbA. More interestingly, this transgenic alga accumulated about 60% more H2 content than the wild-type strain CC-849 at the end of 7-day cultivation. Conclusions: The photobio-H2 production in the engineered transgenic alga was significantly improved. Without imposing any nutrient-deprived stress, this novel strategy provided a convenient and efficient way for regulation of photobio-H2 production in green microalga by simply "turn on" the expression of a designed amiRNA.

From the circular economy point of view, direct residues from these industries exploited for production of fuel/chemicals is a winning issue, because it reduces the environmental/cost impact and improves the eco sustainability of productions. Results: The present paper reports recent results of deep eutectic solvent (DES) pretreatment on a selected group of the agro industrial food wastes (AFWs) produced in Europe. In particular, apple residues, potato peels, coffee silverskin, and brewer's spent grains were pretreated with two DESs, (choline chloride-glycerol and choline chloride-ethylene glycol) for fermentable sugar production. Pretreated biomass was enzymatic digested by commercial enzymes to produce fermentable sugars. Operating conditions of the DES pretreatment were changed in wide intervals. The solid to solvent ratio ranged between 1:8 and 1:32, and the temperature between 60 and 150 degrees C. The DES reaction time was set at 3 h. Optimal operating conditions were: 3 h pretreatment with choline chloride-glycerol at 1:16 biomass to solvent ratio and 115 degrees C. Moreover, to assess the expected European amount of fermentable sugars from the investigated AFWs, a market analysis was carried out. The overall sugar production was about 217 kt yr-1, whose main fraction was from the hydrolysis of BSGs pretreated with choline chloride-glycerol DES at the optimal conditions. Conclusions: The reported results boost deep investigation on lignocellulosic biomass using DES. This investigated new class of solvents is easy to prepare, biodegradable and cheaper than ionic liquid. Moreover, they reported good results in terms of sugars' release at mild operating conditions (time, temperature and pressure). PMID- 29449886 TI - Off-label use of IV t-PA in patients with intracranial neoplasm and cavernoma. AB - Background: The safety of systemic thrombolysis in patients with intracranial tumor and cavernoma are unknown. So far evidence is limited to a number of case reports and few case series or unspecified data based on population-based analysis. Our aim was to comprehend the risk of systemic thrombolysis in these patients. Methods: Patients with additional evidence of intracranial tumor or cavernoma who received IV tissue plasminogen activator (t-PA) treatment at our comprehensive stroke center over a period of 7 years were identified in our stroke database and compared to the same number of matched control subjects without any evidence of intracranial tumor and cavernoma. Clinical history and imaging patterns before and after t-PA therapy were individually reviewed for each patient. Results: Thirty-four patients with additional evidence of meningioma (19/34), cavernoma (13/34) or malignant intracranial neoplasm (2/34) were identified. The incidence of secondary intracranial hemorrhage observed showed no difference between control subjects (9/34, 26%) and patients (6/34, 18%; p = 0.56). Symptomatic hemorrhage in patients with meningioma or cavernoma could not be observed. Likewise, the prevalence of stroke mimics showed no difference between patients (8/34, 24%) and control subjects (5/34, 15%; p = 0.54). However, both patients with malignant intracranial neoplasm presented with a stroke mimic and intracranial hemorrhage was observed in one of them. Conclusions: In compliance with existing evidence, treatment in patients with meningioma and cavernoma appears to be safe and reasonable, while the therapy should be avoided in patients with malignant intracranial neoplasm with blood brain barrier disruption. PMID- 29449888 TI - Towards hope. PMID- 29449889 TI - How primary care can contribute to good mental health in adults. AB - The need for support for good mental health is enormous. General support for good mental health is needed for 100% of the population, and at all stages of life, from early childhood to end of life. Focused support is needed for the 17.6% of adults who have a mental disorder at any time, including those who also have a mental health problem amongst the 30% who report having a long-term condition of some kind. All sectors of society and all parts of the NHS need to play their part. Primary care cannot do this on its own. This paper describes how primary care practitioners can help stimulate such a grand alliance for health, by operating at four different levels - as individual practitioners, as organisations, as geographic clusters of organisations and as policy-makers. PMID- 29449890 TI - Benefits, harms and evidence - reflections from UK primary healthcare. AB - : In this paper I examine the relationship between benefits, harms and evidence based medicine in the context of British primary healthcare. First, I will examine: 'What is a benefit and what is a harm?' Second, what should we know about where the balance of risk and benefit appear to lie? Third, what should we do with this knowledge, particularly in the context of the biopsychosocial gaze of primary care? I conclude that even perfect knowledge about benefits and harms requires to be translated in the context of the individual patient: it also requires to be interpreted according to what that persons' wishes are. Why this matters to me: By reiterating again and again how biases are stacked in favour of recommending treatments and interventions well beyond their rational evidence, my hope is that more honest medicine will result in less but higher value medicine. Stopping doing things that don't work, or work rarely, or come with an unacceptable burden of side effects or appointments should make room for the pleasure of practicing medicine. Key messages: *Even perfect knowledge about benefits and harms requires to be translated in the context of the individual patient: it also requires to be interpreted according to what that persons' wishes are.*In the real, messy frontline world of general practice, we will always have uncertainty about where the balance of risk and benefit might lie. PMID- 29449887 TI - Role of the T and B lymphocytes in pathogenesis of autoimmune thyroid diseases. AB - Autoimmune thyroid disorders (AITD) broadly include Graves' disease and Hashimoto's thyroiditis which are the most common causes of thyroid gland dysfunctions. These disorders develop due to complex interactions between environmental and genetic factors and are characterized by reactivity to self thyroid antigens due to autoreactive lymphocytes escaping tolerance. Both cell mediated and humoral responses lead to tissue injury in autoimmune thyroid disease. The differentiation of CD4+ cells in the specific setting of immune mediators (for example cytokines, chemokines) results in differentiation of various T cell subsets. T cell identification has shown a mixed pattern of cytokine production indicating that both subtypes of T helper, Th1 and Th2, responses are involved in all types of AITD. Furthermore, recent studies described T cell subtypes Th17 and Treg which also play an essential role in pathogenesis of AITD. This review will focus on the role of the T regulatory (Treg) and T helper (Th) (especially Th17) lymphocytes, and also of B lymphocytes in AITD pathogenesis. However, we have much more to learn about cellular mechanisms and interactions in AITD before we can develop complete understanding of AITD pathophysiology. PMID- 29449891 TI - Considering change. PMID- 29449892 TI - Possible correlation between gut microbiota and immunity among healthy middle aged and elderly people in southwest China. AB - Background: The present study was conducted to investigate the possible association between gut microbes and immunity among healthy middle-aged and elderly individuals in southwest China. A total of 148 healthy adults aged >= 50 years were divided into two age groups: middle-aged group (50-59 years; n = 67, 54.13 +/- 3.32) and elderly group (>= 60 years; n = 81, 64.70 +/- 3.93). Blood samples were collected to measure serum immune and biochemical indices. Gut microbiota compositions of the groups were characterized on the basis of faecal DNA using 16S rRNA gene sequencing. Results: Among the detected gut microbes, the presence of Alistipes was negatively correlated with age in both groups. In the middle-aged group, age was negatively correlated with the presence of Desulfovibrio and Faecalibacterium. In the elderly group, Coprococcus was present at significantly higher levels; age was negatively correlated with the presence of Lachnobacterium, Oxalobacter and the Chao index, whereas positively correlated with the presence of Sutterella. In the middle-aged group, the presence of Bacteroidetes was positively correlated with serum immunoglobulin G (IgG) levels and the percent of CD8+ T cells and negatively correlated with the CD4+/CD8+ ratio; the presence of Firmicutes was negatively correlated with IgM levels; Bacteroidetes/Firmicutes ratio was positively correlated with IgG and IgM levels and Simpson index was negatively correlated with the percent of CD8+ T cells and positively correlated with CD4+/CD8+ ratio. In the elderly group, the presence of Verrucomicrobia (identified as genus Akkermansia) was positively correlated with IgA levels and the percent of CD8+ T cells and negatively correlated with the percent of CD4+ T cells and CD4+/CD8+ ratio; the Chao index and observed species were positively correlated with IgA levels. Conclusions: These results indicated that ageing could significantly correlate with the composition of gut microbiota in terms of quantity and quality. Changes in gut microbiota caused by ageing, characterized by decreased Bacteroidetes levels, might be associated with immunosenescence among healthy middle-aged and elderly people in southwest China. PMID- 29449893 TI - Endoplasmic reticulum stress activation in adipose tissue induces metabolic syndrome in individuals with familial partial lipodystrophy of the Dunnigan type. AB - Background: Familial partial lipodystrophy of the Dunnigan type is one of the most common inherited lipodystrophies variables. These individuals have important metabolic disorders that cause predisposition to various diseases. In this study we aimed to demonstrate the relation between the metabolic abnormalities, inflammatory profile and the expression of genes involved in the activation of the endoplasmic reticulum stress (ERS) in subjects with FPLD. Methods: We evaluated 14 female FPLD patients and compared with 13 female healthy individuals. The subjects were paired with their respective BMI and age and categorized into two groups: Familial partial lipodystrophy of the Dunnigan type (FPLD) and control. Patients were fasted for 12 h before blood collection for measurement of HbA1c, glucose, insulin, lipids and inflammatory markers. Subcutaneous adipose tissue was collected by puncture aspiration of submental region during ambulatorial surgical aesthetic procedure. Results: We demonstrate that patients with FPLD show increased HbA1c (p < 0.01), fasting glucose (p < 0.002) and triglycerides (p < 0.005) while HDL/cholesterol (p < 0.001) was lower when compared to healthy individuals. We found that 64.2% FPLD patients had metabolic syndrome according to International Diabetes Federation definition. We also observe increased AUC of glucose (p < 0.001) and insulin during oGTT, featuring a frame of hyperglycemia and hyperinsulinemia, suggesting insulin resistance. Also we found hyperactivation of several genes responsible for ERS such as ATF-4 (p < 0.01), ATF-6 (p < 0.01), EIF2alpha3K (p < 0.005), CCT4 (p < 0.001), CHOP (p < 0.01), CALR (p < 0.001) and CANX (p < 0.005), that corroborate the idea that diabetes mellitus and metabolic syndrome are associated with direct damage to the endoplasmic reticulum homeostasis. Ultimately, we note that individuals with lipodystrophy have an increase in serum interleukins, keys of the inflammatory process, as IL-1beta, TNF-alpha and IL-6 (p < 0.05 all), compared with healthy individuals, which can be the trigger to insulin resistance in this population. Conclusion: Individuals with FPLD besides having typical dysfunctions of metabolic syndrome, show a hyperactivation of ERS associated with increased systemic inflammatory profile, which together may explain the complex clinical aspect of this diseases.Trial registration HCRP no 6711/2012. PMID- 29449894 TI - Personalization of regorafenib treatment in metastatic gastrointestinal stromal tumours in real-life clinical practice. AB - Background: Regorafenib (REG) has now been approved as the standard third-line therapy in metastatic gastrointestinal stromal tumour (GIST) patients at the recommended dose and schedule of 160 mg once daily for the first 3 weeks of each 4-week cycle. However, it has a relevant toxicity profile that mainly occurs within the first cycles of therapy, and dose and schedule adjustments are often required to reduce the frequency or severity of adverse events and to avoid early treatment discontinuation. To date, large amounts of data on the use of REG in metastatic GIST patients in daily clinical practice are not available, and we lack information about how this treatment personalization really affects the quality of life (QoL) of patients. The aim of the present retrospective study is to build a comprehensive picture of all alternative REG strategies adopted in daily clinical practice for use in metastatic GIST patients. Methods: Metastatic GIST patients treated with dose adjustment or alternative schedules of REG at seven reference Italian centres were retrospectively included. Results: For a total of 62 metastatic GIST patients, we confirmed that REG treatment adjustment is common in clinical practice and that it is very heterogeneous, with approximately 20 different strategies being adopted. Independent of which strategy is chosen, treatment personalization has led to a clinical benefit defined as complete or partial resolution of side effects in almost all patients, affecting the duration of REG treatment. Conclusions: The personalization of REG, even if it is heterogeneous, seems to be crucial to maximize the overall treatment duration. PMID- 29449895 TI - DNM3, p65 and p53 from exosomes represent potential clinical diagnosis markers for glioblastoma multiforme. AB - Background: Glioblastoma multiforme (GBM) is the most aggressive and deadly primary brain cancer that arises from astrocytes and classified as grade IV. Recently, exosomes have been reported as an essential mediator in diverse cancer carcinogenesis and metastasis. However, their role in GBM is still unclear. In this study, we aimed to investigate whether blood exosomes can be potential clinical diagnostic markers for GBM. Methods: We used a xenograft orthotopic mouse model to detect the differentially expressed genes in the brain and blood exosomes of original/recurrent GBM. Results: We found that recurrent GBM had stronger growth capacity and lethality than original GBM in the mouse model. A gene microarray of original tumors and blood exosomes from GBM orthotopic xenografts results showed that DNM3, p65 and CD117 expressions increased, whereas PTEN and p53 expressions decreased in both original tumors and blood exosomes. In the recurrent GBM tumor model, DNM3 and p65 showed increased expressions, whereas ST14 and p53 showed decreased expressions in tumor and blood exosomes of the recurrent GBM mouse model. Conclusion: In summary, we found that DNM3, p65 and p53 had a similar trend in brain and blood exosomes both for original and recurrent GBM, and could serve as potential clinical diagnostic markers for GBM. PMID- 29449896 TI - Myxofibrosarcoma primary cultures: molecular and pharmacological profile. AB - Background: Myxofibrosarcoma (MFS), formerly considered as a myxoid variant of malignant fibrous histiocytoma, is the most common sarcoma of the extremities in adults and is characterized by a high frequency of local recurrence. The clinical behavior of MFS is unpredictable and the efficacy of chemotherapy is still not well documented. Furthermore, given the relatively recent recognition of MFS as a distinct pathologic entity its cellular and molecular biology has still not been extensively studied in patient-derived preclinical models. We examined the molecular biology and treatment outcomes of high-grade, patient-derived MFS primary cultures. Methods: A total of three patient-derived MFS primary cultures were analyzed. We evaluated the role of CD109 expression and also looked for a correlation between transforming growth factor-beta (TGF-beta) expression and sensitivity of the primary cultures to different drugs. Results: CD109 was a promising marker for the identification of more aggressive high-grade MFS and a potential therapeutic target. The results also highlighted the potential role of TGF-beta in chemoresistance. Pharmacological analysis confirmed the sensitivity of the cultures to chemotherapy. The most active treatments were epirubicin alone and epirubicin in combination with ifosfamide, the latter representing the current standard of care for soft tissue sarcomas (STSs), including MFS. Conclusions: Our results provide a starting point for further research aimed at improving the management of MFS patients undergoing chemotherapy. PMID- 29449897 TI - Atezolizumab: feasible second-line therapy for patients with non-small cell lung cancer? A review of efficacy, safety and place in therapy. AB - Advanced non-small cell lung cancer (NSCLC) prognosis is still poor and has recently been reformed by the development of immune checkpoint inhibitors and the approval of anti-PD-1 (programmed cell-death 1) treatments such as nivolumab and pembrolizumab in second line. More recently, atezolizumab (MDPL 3280A), a programmed cell-death-ligand 1 (PD-L1) inhibitor, was also studied in this setting. Here, we report a review of the literature assessing the efficacy, safety, and place of atezolizumab in the second-line treatment of advanced NSCLC. We performed a literature search of PubMed, American Society of Clinical Oncology, European Society of Medical Oncology and World Conference on Lung Cancer meetings. Atezolizumab showed a good tolerance profile and efficacy in comparison with docetaxel for second-line treatment of advanced NSCLC. Potential predictive biomarkers also have to be assessed. PMID- 29449898 TI - Targeted therapy of brain metastases: latest evidence and clinical implications. AB - Brain metastases (BM) occur in 20-40% of patients with cancer and 60-75% of patients with BM become symptomatic. Due to an aging population and advances in the treatment of primary cancers, patients are living longer and are more likely to experience complications from BM. The diagnosis of BM drastically worsens long term survival rates, with multiple metastases being a poor prognostic factor. Until recently, the mainstay of treatment consisted of stereotactic radiosurgery (SRS), surgical resection, whole brain radiation therapy (WBRT), or a combination of these modalities. Systemic chemotherapy has been felt largely ineffective in the treatment of BM due to the presence of the blood-brain barrier (BBB), which includes efflux pumps on brain capillaries. Over the past decade however, researchers have identified therapeutic agents that are able to cross the BBB. These findings could make a multimodality treatment approach possible, consisting of surgery, radiation, immunotherapy, and targeted therapy, which could lead to better disease control in this patient population and prolong survival. In this review, we discuss present evidence on available targeted therapies and their role in the treatment of BM from primary tumors with the highest prevalence of central nervous system (CNS) involvement, specifically non-small cell lung cancer (NSCLC), breast cancer melanoma, and renal cell carcinoma. PMID- 29449900 TI - Somatostatin analogs: is one better than other? PMID- 29449899 TI - FOXC1 in cancer development and therapy: deciphering its emerging and divergent roles. AB - Forkhead box C1 (FOXC1) is an essential member of the forkhead box transcription factors and has been highlighted as an important transcriptional regulator of crucial proteins associated with a wide variety of carcinomas. FOXC1 regulates tumor-associated genes and is regulated by multiple pathways that control its mRNA expression and protein activity. Aberrant FOXC1 expression is involved in diverse tumorigenic processes, such as abnormal cell proliferation, cancer stem cell maintenance, cancer migration, and angiogenesis. Herein, we review the correlation between the expression of FOXC1 and tumor behaviors. We also summarize the mechanisms of the regulation of FOXC1 expression and activity in physiological and pathological conditions. In particular, we focus on the pathological processes of cancer targeted by FOXC1 and discuss whether FOXC1 is good or detrimental during tumor progression. Moreover, FOXC1 is highlighted as a clinical biomarker for diagnosis or prognosis in various human cancers. The information reviewed here should assist in experimental designs and emphasize the potential of FOXC1 as a therapeutic target for cancer. PMID- 29449901 TI - Recently integrated Alu insertions in the squirrel monkey (Saimiri) lineage and application for population analyses. AB - Background: The evolution of Alu elements has been ongoing in primate lineages and Alu insertion polymorphisms are widely used in phylogenetic and population genetics studies. Alu subfamilies in the squirrel monkey (Saimiri), a New World Monkey (NWM), were recently reported. Squirrel monkeys are commonly used in biomedical research and often require species identification. The purpose of this study was two-fold: 1) Perform locus-specific PCR analyses on recently integrated Alu insertions in Saimiri to determine their amplification dynamics, and 2) Identify a subset of Alu insertion polymorphisms with species informative allele frequency distributions between the Saimiri sciureus and Saimiri boliviensis groups. Results: PCR analyses were performed on a DNA panel of 32 squirrel monkey individuals for 382 Alu insertion events <=2% diverged from 46 different Alu subfamily consensus sequences, 25 Saimiri specific and 21 NWM specific Alu subfamilies. Of the 382 loci, 110 were polymorphic for presence / absence among squirrel monkey individuals, 35 elements from 14 different Saimiri specific Alu subfamilies and 75 elements from 19 different NWM specific Alu subfamilies (13 of 46 subfamilies analyzed did not contain polymorphic insertions). Of the 110 Alu insertion polymorphisms, 51 had species informative allele frequency distributions between Saimiri sciureus and Saimiri boliviensis groups. Conclusions: This study confirms the evolution of Alu subfamilies in Saimiri and provides evidence for an ongoing and prolific expansion of these elements in Saimiri with many active subfamilies concurrently propagating. The subset of polymorphic Alu insertions with species informative allele frequency distribution between Saimiri sciureus and Saimiri boliviensis will be instructive for specimen identification and conservation biology. PMID- 29449902 TI - SERS-fluorescence bimodal nanoprobes for in vitro imaging of fatty acid responsive receptor GPR120. AB - G-protein-coupled receptor 120 (GPR120), as a member of the rhodopsin family of G protein-coupled receptors, has been shown to function as a sensor for dietary fat in the gustatory and digestive systems. Its specific role in the chemoreception of fatty acids, which is thought to be crucial in understanding the mechanism surrounding the control of fat intake and, accordingly, in the treatment of obesity, remains unclear. Here we report a novel surface-enhanced Raman spectroscopy (SERS)-fluorescence bimodal microscopic technique for detection and imaging of GPR120 in single living cells. CaMoO4:Eu3+@AuNR hybrid nanoparticles are synthesized and characterized as imaging probes. Biocompatibility and imaging capability of the probes are investigated using a model HEK293 cell line with an inducible GPR120 gene transfection. Cellular distribution of GPR120 is visualized by single-cell SERS and fluorescence imaging. A dose-dependent GPR120 response to linoleic acid treatment is revealed by SERS. PMID- 29449904 TI - Expression profiling of chromatin-modifying enzymes and global DNA methylation in CD4+ T cells from patients with chronic HIV infection at different HIV control and progression states. AB - Background: Integration of human immunodeficiency virus type 1 (HIV-1) into the host genome causes global disruption of the chromatin environment. The abundance level of various chromatin-modifying enzymes produces these alterations and affects both the provirus and cellular gene expression. Here, we investigated potential changes in enzyme expression and global DNA methylation in chronically infected individuals with HIV-1 and compared these changes with non-HIV infected individuals. We also evaluated the effect of viral replication and degree of disease progression over these changes. Results: Individuals with HIV-1 had a significant surge in the expression of DNA and histone methyltransferases (DNMT3A and DNMT3B, SETDB1, SUV39H1) compared with non-infected individuals, with the exception of PRMT6, which was downregulated. Some histone deacetylases (HDAC2 and HDAC3) were also upregulated in patients with HIV. Among individuals with HIV-1 with various degrees of progression and HIV control, the group of treated patients with undetectable viremia showed greater differences with the other two groups (untreated HIV-1 controllers and non-controllers). These latter two groups exhibited a similar behavior between them. Of interest, the overexpression of genes that associate with viral protein Tat (such as SETDB1 along with DNMT3A and HDAC1, and SIRT-1) was more prevalent in treated patients. We also observed elevated levels of global DNA methylation in individuals with HIV-1 in an inverse correlation with the CD4/CD8 ratio. Conclusions: The current study shows an increase in chromatin-modifying enzymes and remodelers and in global DNA methylation in patients with chronic HIV-1 infection, modulated by various levels of viral control and progression. PMID- 29449905 TI - Searching for Silver Linings: Is Perceived Medical Discrimination Weaker in Segregated Areas? AB - An ongoing obstacle in dealing with minority health disparities is discriminatory behavior from healthcare practitioners, also known as medical discrimination. It is not clear, however, if the effects of medical discriminations onto health are constant across space. For example, there is evidence to suspect minorities in racially segregated neighborhoods suffer less from discrimination compared to those living elsewhere. To determine the presence of spatial heterogeneity underlying medical discrimination, we implement logistic geographically weighted regression (GWR) using individual data in the city of Philadelphia from the 2006 and 2008 Public Health Management Corporation's Southeastern Pennsylvania Household Health Surveys. Evaluating the potential role residential segregation has in offsetting medical discrimination, we compare the GWR results to tract data from the 2005-2009 American Community Survey. Through this comparison, we find that the effects of medical discrimination on self-rated health are weaker in magnitude in areas that are mostly minority. However, evidence of direct health benefits for minorities in segregated communities is inconclusive. Thus, while we cannot say living in segregated neighborhoods leads to better minority health, the sting of medical discrimination can be weaker in these places. These results emphasize the importance of local variation, even within a city like Philadelphia, challenging the aspatial one-model-fits-all approach normally found in population studies. PMID- 29449903 TI - Specific or not specific recruitment of DNMTs for DNA methylation, an epigenetic dilemma. AB - Our current view of DNA methylation processes is strongly moving: First, even if it was generally admitted that DNMT3A and DNMT3B are associated with de novo methylation and DNMT1 is associated with inheritance DNA methylation, these distinctions are now not so clear. Secondly, since one decade, many partners of DNMTs have been involved in both the regulation of DNA methylation activity and DNMT recruitment on DNA. The high diversity of interactions and the combination of these interactions let us to subclass the different DNMT-including complexes. For example, the DNMT3L/DNMT3A complex is mainly related to de novo DNA methylation in embryonic states, whereas the DNMT1/PCNA/UHRF1 complex is required for maintaining global DNA methylation following DNA replication. On the opposite to these unspecific DNA methylation machineries (no preferential DNA sequence), some recently identified DNMT-including complexes are recruited on specific DNA sequences. The coexistence of both types of DNA methylation (un/specific) suggests a close cooperation and an orchestration between these systems to maintain genome and epigenome integrities. Deregulation of these systems can lead to pathologic disorders. PMID- 29449906 TI - Elucidating the Vibrational Fingerprint of the Flexible Metal-Organic Framework MIL-53(Al) Using a Combined Experimental/Computational Approach. AB - In this work, mid-infrared (mid-IR), far-IR, and Raman spectra are presented for the distinct (meta)stable phases of the flexible metal-organic framework MIL 53(Al). Static density functional theory (DFT) simulations are performed, allowing for the identification of all IR-active modes, which is unprecedented in the low-frequency region. A unique vibrational fingerprint is revealed, resulting from aluminum-oxide backbone stretching modes, which can be used to clearly distinguish the IR spectra of the closed- and large-pore phases. Furthermore, molecular dynamics simulations based on a DFT description of the potential energy surface enable determination of the theoretical Raman spectrum of the closed- and large-pore phases for the first time. An excellent correspondence between theory and experiment is observed. Both the low-frequency IR and Raman spectra show major differences in vibrational modes between the closed- and large-pore phases, indicating changes in lattice dynamics between the two structures. In addition, several collective modes related to the breathing mechanism in MIL-53(Al) are identified. In particular, we rationalize the importance of the trampoline-like motion of the linker for the phase transition. PMID- 29449907 TI - Electrospun Conjugated Polymer/Fullerene Hybrid Fibers: Photoactive Blends, Conductivity through Tunneling-AFM, Light Scattering, and Perspective for Their Use in Bulk-Heterojunction Organic Solar Cells. AB - Hybrid conjugated polymer/fullerene filaments based on MEH-PPV/PVP/PCBM were prepared by electrospinning, and their properties were assessed by scanning electron, atomic and lateral-force, tunneling, and confocal microscopies, as well as by attenuated-total-reflection Fourier transform infrared spectroscopy, photoluminescence quantum yield, and spatially resolved fluorescence. Highlighted features include the ribbon shape of the realized fibers and the persistence of a network serving as a template for heterogeneous active layers in solar cell devices. A set of favorable characteristics is evidenced in this way in terms of homogeneous charge-transport behavior and formation of effective interfaces for diffusion and dissociation of photogenerated excitons. The interaction of the organic filaments with light, exhibiting specific light-scattering properties of the nanofibrous mat, might also contribute to spreading incident radiation across the active layers, thus potentially enhancing photovoltaic performance. This method might be applied to other electron donor-electron acceptor material systems for the fabrication of solar cell devices enhanced by nanofibrillar morphologies embedding conjugated polymers and fullerene compounds. PMID- 29449908 TI - PET/CT in the Evaluation of Relapsed or Refractory Hodgkin Lymphoma. AB - 18F-fluorodeoxyglucose-positron emission tomography (FDG-PET) has been the most important advance in the assessment of Hodgkin lymphoma (HL) since the introduction of computed tomography (CT). In the frontline management of HL, FDG PET combined with low-dose CT has emerged as the modality of choice for staging and treatment response assessment. Substantial data have accumulated over the past several years supporting the use of PET/CT in the evaluation and management of relapsed or refractory HL, as well. In this article, we review the role of PET/CT after the frontline treatment of HL, as well as the prognostic utility of PET/CT before autologous and allogeneic stem cell transplantation. We also review the use of PET/CT as a part of response-adapted treatment strategies in relapsed or refractory HL and implications for current and future clinical practice. PMID- 29449909 TI - Alterations in the inferior longitudinal fasciculus in autism and associations with visual processing: a diffusion-weighted MRI study. AB - Background: One of the most reported neural features of autism spectrum disorder (ASD) is the alteration of multiple long-range white matter fiber tracts, as assessed by diffusion-weighted imaging and indexed by reduced fractional anisotropy (FA). Recent methodological advances, however, have shown that this same pattern of reduced FA may be an artifact resulting from excessive head motion and poorer data quality and that aberrant structural connectivity in children with ASD is confined to the right inferior longitudinal fasciculus (ILF). This study aimed at replicating the observation of reduced FA along the right ILF in ASD, while controlling for group differences in head motion and data quality. In addition, we explored associations between reduced FA in the right ILF and quantitative ASD characteristics, and the involvement of the right ILF in visual processing, which is known to be altered in ASD. Method: Global probabilistic tractography was performed on diffusion-weighted imaging data of 17 adolescent boys with ASD and 17 typically developing boys, matched for age, performance IQ, handedness, and data quality. Four tasks were administered to measure various aspects of visual information processing, together with questionnaires assessing ASD characteristics. Group differences were examined and the neural data were integrated with previously published findings using Bayesian statistics to quantify evidence for replication and to pool data and thus increase statistical power. (Partial) correlations were calculated to investigate associations between measures. Results: The ASD group showed consistently reduced FA only in the right ILF and slower performance on the visual search task. Bayesian statistics pooling data across studies confirmed that group differences in FA were confined to the right ILF only, with the evidence for altered FA in the left ILF being indecisive. Lower FA in the right ILF tended to covary with slower visual search and a more fragmented part-oriented processing style. Individual differences in FA of the right ILF were not reliably associated with the severity of ASD traits after controlling for clinical status. Conclusion: Our findings support the growing evidence for reduced FA along a specific fiber tract in ASD, the right ILF. PMID- 29449910 TI - Design, Synthesis and Preliminary Antimicrobial Evaluation of N-Alkyl Chain Tethered C-5 Functionalized Bis-Isatins. AB - A series of N-alkyl tethered C-5 functionalized bis-isatins were synthesized and evaluated for antimicrobial activity against pathogenic microorganisms. The preliminary evaluation studies revealed the compound 4t, with an optimal combination of bromo-substituent at the C-5 position of isatin ring along with propyl chain linker being most active among the synthesized series exhibiting an IC50 value of 3.72 MUM against Trichomonas vaginalis while 4j exhibited an IC50 value of 14.8 MUM against Naegleria fowleri, more effective than the standard drug Miltefosine. The compound 3f with an octyl spacer length was the most potent among the series against Giardia lamblia with an IC50 of 18.4 MUM while 3d exhibited an IC50 of 23 MUM against Entamoeba histolytica. This library was also screened against the fungal pathogen Aspergillus parasiticus. A number of the compounds demonstrated potency against this fungus, illustrating a possible broad spectrum activity. Furthermore, an evaluation of these synthesized compounds against a panel of normal flora bacteria revealed them to be non-cytotoxic, demonstrating the selectivity of these compounds. This observation, in combination with previous studies that isatin is non-toxic to humans, presents a new possible scaffold for drug discovery against these important protozoal pathogens of humans and animals. PMID- 29449911 TI - Differences for traits associated with early N acquisition in a grain legume and early complementarity in grain legume-triticale mixtures. AB - Early strategies of crop growth and N acquisition can be critical for determining competitive interactions between weeds and crops. Grain legumes and especially lupins are known to be poor competitors against weeds. Grain legumes are known to have low mineral soil N uptake abilities. However, inter- and intraspecific differences in N uptake ability in relation to below-ground traits have received little attention. Our objectives were (i) to measure differences among lupins for a set of traits associated with early growth and N acquisition; (ii) to examine how this variation compares to differences between lupin and a cereal, triticale, and (iii) to assess if mixing lupin with triticale provides a higher potential than does pure lupin regarding plant biomass and mineral soil N acquisition early in the crop cycle. Lupin (12 genotypes) and triticale plants were grown separately and in mixed species pairs in a replacement design for 1 and 2 months in three rhizotron experiments. Shoot and root biomass, root length, root expansion dynamics, N2 fixation and mineral soil N uptake were measured. Differences among lupin species and genotypes regarding traits related to early growth and to mineral soil N uptake were observed, but all lupins demonstrated slow early growth and low ability to absorb mineral soil N compared to triticale. In lupin-triticale mixture, a contrast in early growth strategies between species induced a higher total soil mineral N uptake compared with pure lupin. Complementarity between lupin and triticale persisted during the second month, when interactions began. This complementarity may allow for reduced competition between species, favouring higher triticale biomass production than in pure triticale, without compromising lupin growth.

AB - Metals have a number of important roles within the brain. We used laser ablation inductively coupled plasma-mass spectrometry (LA-ICP-MS) to map the three dimensional concentrations and distributions of transition metals, in particular iron (Fe), copper (Cu) and zinc (Zn) within the murine brain. LA-ICP-MS is one of the leading analytical tools for measuring metals in tissue samples. Here, we present a complete data reduction protocol for measuring metals in biological samples, including the application of a pyramidal voxel registration technique to reproducibly align tissue sections. We used gold (Au) nanoparticle and ytterbium (Yb)-tagged tyrosine hydroxylase antibodies to assess the co-localisation of Fe and dopamine throughout the entire mouse brain. We also examined the natural clustering of metal concentrations within the murine brain to elucidate areas of similar composition. This clustering technique uses a mathematical approach to identify multiple 'elemental clusters', avoiding user bias and showing that metal composition follows a hierarchical organisation of neuroanatomical structures. This work provides new insight into the distinct compartmentalisation of metals in the brain, and presents new avenues of exploration with regard to region specific, metal-associated neurodegeneration observed in several chronic neurodegenerative diseases. PMID- 29449913 TI - On-off switch of charge-separated states of pyridine-vinylene-linked porphyrin C60 conjugates detected by EPR. AB - The design, synthesis, and electronic properties of a new series of D-pi-A conjugates consisting of free base (H2P) and zinc porphyrins (ZnP) as electron donors and a fullerene (C60) as electron acceptor, in which the two electroactive entities are covalently linked through pyridine-vinylene spacers of different lengths, are described. Electronic interactions in the ground state were characterized by electrochemical and absorption measurements, which were further supported with theoretical calculations. Most importantly, charge-transfer bands were observed in the absorption spectra, indicating a strong push-pull behavior. In the excited states, electronic interactions were detected by selective photoexcitation under steady-state conditions, by time-resolved fluorescence investigations, and by pump probe experiments on the femto-, pico-, and nanosecond time scales. Porphyrin fluorescence is quenched for the different D-pi A conjugates, from which we conclude that the deactivation mechanisms of the excited singlet states are based on photoinduced energy- and/or electron transfer processes between H2P/ZnP and C60, mediated through the molecular spacers. The fluorescence intensity decreases and the fluorescence lifetimes shorten as the spacer length decreases and as the spacer substitution changes. With the help of transient absorption spectroscopy, the formation of charge-separated states involving oxidized H2P/ZnP and reduced C60 was confirmed. Lifetimes of the corresponding charge-separated states, which ranged from ~400 picoseconds to 165 nanoseconds, depend on the spacer length, the spacer substitution, and the solvent polarity. Interestingly, D-pi-A conjugates containing the longest linkers did not necessarily exhibit the longest charge-separated state lifetimes. The distances between the electron donors and the acceptors were calculated by molecular modelling. The longest charge-separated state lifetime corresponded to the D-pi-A conjugate with the longest electron donor-acceptor distance. Likewise, EPR measurements in frozen media revealed charge separated states in all the D-pi A conjugates investigated. A sharp peak with g values ~2.000 was assigned to reduced C60, while a broader, less intense signal (g ~ 2.003) was assigned to oxidized H2P/ZnP. On-off switching of the formation and decay of the charge separated states was detected by EPR at 77 K by repeatedly turning the irradiation source on and off. PMID- 29449914 TI - Cycloaddition of cyclobutenone and azomethine imine enabled by chiral isothiourea organic catalysts. AB - The addition of an organic catalyst to the ketone moiety of a gamma-mono-chloride substituted cyclobutenone destroys its stable, conjugated and nearly planar structure. The C-C bond in the resulting less stable anionic oxy-substituted non planar intermediate is then activated. The breaking of one C-C single bond leads to a catalyst-bound intermediate that undergoes alpha-carbon selective reactions with azomethine imines to afford nitrogen-containing heterocyclic compounds with excellent diastereo- and enantio-selectivities. Our organocatalytic approach provides a new reaction pattern for C-C bond activation of cyclobutenones that is unavailable with transition metal catalysis. In addition, the present study with isothioureas as the organocatalysts expands the potential in using organocatalysts for C-C bond breaking and selective reactions. PMID- 29449915 TI - NHC-catalysed benzoin condensation - is it all down to the Breslow intermediate? AB - The Breslow catalytic cycle describing the benzoin condensation promoted by N heterocyclic carbenes (NHC) as proposed in the late 1950s has since then been tried by generations of physical organic chemists. Emphasis has been laid on proofing the existence of an enaminol like structure (Breslow intermediate) that explains the observed umpolung of an otherwise electrophilic aldehyde. The present study is not focusing on spectroscopic elucidation of a thiazolydene based Breslow intermediate but rather tries to clarify if this key-intermediate is indeed directly linked with the product side of the overall reaction. The here presented EPR-spectroscopic and computational data provide a fundamentally different view on how the benzoin condensation may proceed: a radical pair could be identified as a second key-intermediate that is derived from the Breslow intermediate via an SET process. These results highlight the close relationship to the Cannizarro reaction and oxidative transformations of aldehydes under NHC catalysis. PMID- 29449916 TI - Critical analysis of the limitations of Bleaney's theory of magnetic anisotropy in paramagnetic lanthanide coordination complexes. AB - The origins of the breakdown of Bleaney's theory of magnetic anisotropy are described, based on an analysis of eleven different complexes of the second half of the 4f elements that form isostructural series. An examination of the chemical shift and relaxation rate behaviour of resonances located at least four bonds away from the paramagnetic centre was undertaken, and correlated to theoretical predictions. The key limitations relate to comparability of ligand field splitting with spin-orbit coupling, variation in the position of the principal magnetic axis between Ln complexes and the importance of multipolar terms in describing lanthanide ligand field interactions. PMID- 29449917 TI - Strain discrimination of Yersinia pestis using a SERS-based electrochemically driven melting curve analysis of variable number tandem repeat sequences. AB - Strain discrimination within genetically highly similar bacteria is critical for epidemiological studies and forensic applications. An electrochemically driven melting curve analysis monitored by SERS has been utilised to reliably discriminate strains of the bacterial pathogen Yersinia pestis, the causative agent of plague. DNA amplicons containing Variable Number Tandem Repeats (VNTRs) were generated from three strains of Y. pestis: CO92, Harbin 35 and Kim. These amplicons contained a 10 base pair VNTR repeated 6, 5, and 4 times in CO92, Harbin 35 and Kim respectively. The assay also included a blocker oligonucleotide comprising 3 repeats of the 10-mer VNTR sequence. The use of the blocker reduced the effective length of the target sequence available to bind to the surface bound probe and significantly improved the sensitivity of the discrimination. The results were consistent during three replicates that were carried out on different days, using different batches of PCR product and different SERS sphere segment void (SSV) substrate. This methodology which combines low cost, speed and sensitivity is a promising alternative to the time consuming current electrophoretic methods. PMID- 29449918 TI - What can NMR spectroscopy of selenoureas and phosphinidenes teach us about the pi accepting abilities of N-heterocyclic carbenes? AB - The electronic nature of the interaction of NHCs with metal centres is of interest when exploring their properties, how these properties influence those of metal complexes, and how these properties might depend on ligand structure. Selenourea and phosphinidene complexes have been proposed to allow the measurement of the pi-accepting ability of NHCs, independent of their sigma donating ability, via the collection of 77Se or 31P NMR spectra, respectively. Herein, the synthesis and characterisation of selenoureas derived from a range of imidazol-2-ylidenes, 4,5-dihydroimidazol-2-ylidenes and triazol-2-ylidenes are documented. Computational studies are used to explore the link between the shielding of the selenium centre and the electronic properties of the NHCs. Results show that deltaSe is correlated to the energy gap between a filled lone pair orbital on Se and the empty pi* orbital corresponding to the Se-NHC bond. Bond energy decomposition analysis indicated no correlation between the orbital sigma-contribution to bonding and the chemical shielding, while a good correlation was found between the pi-contribution to bonding and the chemical shielding, confirming that this technique is indeed able to quantify the ability of NHCs to accept pi-electron density. Calculations conducted on phosphinidene adducts yielded similar results. With the link between deltaSe and deltaP and pi back bonding ability clearly established, these compounds represent useful ways in which to fully understand and quantify this aspect of the electronic properties of NHCs.

AB - The oxidative olefination of a broad array of arenes and heteroarenes with a variety of activated and unactivated olefins has be achieved via a rhodium(iii) catalyzed C-H activation reaction. The use of an N-pentafluorophenyl benzamide directing group is crucial for achieving catalytic turnovers in the presence of air as the sole oxidant without using a co-oxidant. PMID- 29449920 TI - A family of N-heterocyclic carbene-stabilized borenium ions for metal-free imine hydrogenation catalysis. AB - This manuscript probes the steric and electronic attributes that lead to "frustrated Lewis pair" (FLP)-type catalysis of imine hydrogenation by borenium ions. Hydride abstraction from (ItBu)HB(C6F5)22 prompts intramolecular C-H bond activation to give (CHN)2(tBu) (CMe2CH2)CB(C6F5)23, defining an upper limit of Lewis acidity for FLP hydrogenation catalysis. A series of seven N-heterocyclic carbene-borane (NHC-borane) adducts ((R'CNR)2C)(HBC8H14) (R' = H, R = dipp 4a, Mes 5a, Me 8a; R = Me R' = Me 9a, Cl, 10a) and ((HC)2(NMe)(NR)C)(HBC8H14) (R = tBu, 6a, Ph 7a) are prepared and converted to corresponding borenium salts. These species are evaluated as catalysts for metal-free imine hydrogenation at room temperature. Systematic tuning of the carbene donor for the hydrogenation of archetypal substrate N-benzylidene-tert-butylamine achieves the highest reported turn-over frequencies for FLP-catalyzed hydrogenation at amongst the lowest reported catalyst loadings. The most active NHC-borenium catalyst of this series, derived from 10a, is readily isolable, crystallographically characterized and shown to be effective in the hydrogenation catalysis of functional group containing imines and N-heterocycles. PMID- 29449921 TI - HMGB1 bound to cisplatin-DNA adducts undergoes extensive acetylation and phosphorylation in vivo. AB - Cisplatin, one of the most effective anticancer drugs, is a DNA-damaging agent that induces cell death primarily by apoptosis. For many years, HMGB1 has been known to be a recognition protein for cisplatin-DNA lesions. Here, an application of a biomolecular probe based on a peptide-oligonucleotide conjugate is presented as a novel method for investigating this recognition process in vivo. Proteins known to be involved in the recognition of cisplatin-damaged DNA were pulled down and identified, including members of the HMGB family and a number of other proteins. Interestingly, at least 4 subforms of HMGB1 bind to cisplatin-DNA adducts. These proteins were further identified as post-translationally acetylated or phosphorylated forms of HMGB1. These results provide a rich pool of protein candidates whose roles in the mechanism of action of platinum drugs should be explored. These newly discovered molecular components of the DNA damage signalling cascade could serve as novel links between the initial cell responses to DNA damage and the downstream apoptotic or DNA repair pathways. PMID- 29449922 TI - Bypassing the lack of reactivity of endo-substituted norbornenes with the catalytic rectification-insertion mechanism. AB - The catalytic 1,2-insertion polymerization of polar norbornenes (NBEs) leads to the formation of functional rigid macromolecules with exceptional thermal, optical and mechanical properties. However, this remarkable reaction is plagued by the low reactivity of the polar monomers, and most notably of those bearing a functional group in endo position. We have examined the polymerization mechanism of NBEs bearing one or two CO2Me groups either in exo or endo position catalyzed by the so-called naked allyl Pd+ SbF6- catalyst (1). Although endo dimethyl ester of 5-norbornene-2,3-dicarboxylic acid (NBE(CO2Me)2) is polymerized by 1, two endo units are never inserted consecutively along the polymer chain. Indeed, 1 is a tandem catalyst which not only catalyzes the insertion of the monomer but also the isomerization of endo and exo isomers. Thus, the polymerization of endo monomers proceeds via a novel mechanism, coined rectification-insertion mechanism, whereby half of the endo monomers are rectified into exo ones prior insertion, leading to the formation of an alternating endo-exo copolymer using an endo only feedstock. With this mechanism, the lack of reactivity of endo norbornenes is bypassed, and the polymerization of predominantly endo polar NBEs bearing a variety of functionalities such as esters, imides, acids, aldehydes, alcohols, anhydrides, or alkyl bromides proceeds with catalyst loadings as low as 0.002 mol%.

The torsional degrees of freedom around the methine bonds provide routes for non radiative decay, responsible for the inherently low fluorescence quantum yields. Using transient absorption spectroscopy, we determined that upon photoexcitation, the excited state relaxes along two parallel pathways producing three excited state transients that undergo internal conversion to the ground state. The media viscosity impedes the molecular modes of ring rotation and preferentially affects one of the pathways of non-radiative decay, exerting a dominant effect on the emission properties of THIA. Concurrently, the polarity affects the energy of the transients involved in the decay pathways and further modulates the kinetics of non-radiative deactivation. PMID- 29449924 TI - Impacts of gold nanoparticle charge and ligand type on surface binding and toxicity to Gram-negative and Gram-positive bacteria. AB - Although nanomaterials facilitate significant technological advancement in our society, their potential impacts on the environment are yet to be fully understood. In this study, two environmentally relevant bacteria, Shewanella oneidensis and Bacillus subtilis, have been used as model organisms to elucidate the molecular interactions between these bacterial classes and Au nanoparticles (AuNPs) with well-controlled and well-characterized surface chemistries: anionic 3-mercaptopropionic acid (MPA), cationic 3-mercaptopropylamine (MPNH2), and the cationic polyelectrolyte poly(allylamine hydrochloride) (PAH). The data demonstrate that cationic, especially polyelectrolyte-wrapped AuNPs, were more toxic to both the Gram-negative and Gram-positive bacteria. The levels of toxicity observed were closely related to the percentage of cells with AuNPs associated with the cell surface as measured in situ using flow cytometry. The NP concentration-dependent binding profiles were drastically different for the two bacteria strains, suggesting the critical role of bacterial cell surface chemistry in determining nanoparticle association, and thereby, biological impact. PMID- 29449925 TI - Redox reaction induced Ostwald ripening for size- and shape-focusing of palladium nanocrystals. AB - We report here that size- and shape-focusing can be achieved through the well known Ostwald ripening process to produce high-quality metal nanocrystals (NCs). Using Pd as an example, we show that the addition of small NCs of appropriate sizes could help in modulating the growth of larger NCs and enable excellent control over both the size and shape uniformity of the products. A detailed mechanistic study showed that the self-focusing of Pd NCs relied on a dissolution and regrowth process induced by redox reaction of HCHO. With the assistance of HCHO, injection of small sacrificial nanocrystals (SNCs), with sizes below a critical value, into larger seeds results in the dissolution of the SNCs and subsequent deposition onto the larger ones, thus allowing the formation of monodisperse Pd NCs. We have identified the critical radius of the SNCs to be ~5.7 nm for Pd, and verified that SNCs with sizes larger than that could not effectively support the growth of larger seeds. More interestingly, since Ostwald ripening involves matter relocation, this synthetic approach could even break the self-termination growth habits of metal NCs and produce nanocrystals with sizes that are not conveniently accessible by direct growth. PMID- 29449927 TI - Unstrained C-C bond activation and directed fluorination through photocatalytically-generated radical cations. AB - Expanding the repertoire of controlled radical fluorination techniques, we present a photosensitized unstrained C-C bond activation/directed monofluorination method using Selectfluor and 9-fluorenone. The reaction is amenable to the opening of multiple 1-acetal-2-aryl substituted rings to yield omega-fluoro carboxylic acids, esters, alcohols, and ketones with relative ease. Initial mechanistic insight suggests radical ion intermediates. PMID- 29449926 TI - Facet selectivity in gold binding peptides: exploiting interfacial water structure. AB - Peptide sequences that can discriminate between gold facets under aqueous conditions offer a promising route to control the growth and organisation of biomimetically-synthesised gold nanoparticles. Knowledge of the interplay between sequence, conformations and interfacial properties is essential for predictable manipulation of these biointerfaces, but the structural connections between a given peptide sequence and its binding affinity remain unclear, impeding practical advances in the field. These structural insights, at atomic-scale resolution, are not easily accessed with experimental approaches, but can be delivered via molecular simulation. A current unmet challenge lies in forging links between predicted adsorption free energies derived from enhanced sampling simulations with the conformational ensemble of the peptide and the water structure at the surface. To meet this challenge, here we use an in situ combination of Replica Exchange with Solute Tempering with Metadynamics simulations to predict the adsorption free energy of a gold-binding peptide sequence, AuBP1, at the aqueous Au(111), Au(100)(1 * 1) and Au(100)(5 * 1) interfaces. We find adsorption to the Au(111) surface is stronger than to Au(100), irrespective of the reconstruction status of the latter. Our predicted free energies agree with experiment, and correlate with trends in interfacial water structuring. For gold, surface hydration is predicted as a chief determining factor in peptide-surface recognition. Our findings can be used to suggest how shaped seed-nanocrystals of Au, in partnership with AuBP1, could be used to control AuNP nanoparticle morphology. PMID- 29449928 TI - Fluorine teams up with water to restore inhibitor activity to mutant BPTI. AB - Introducing fluorine into molecules has a wide range of effects on their physicochemical properties, often desirable but in most cases unpredictable. The fluorine atom imparts the C-F bond with low polarizability and high polarity, and significantly affects the behavior of neighboring functional groups, in a covalent or noncovalent manner. Here, we report that fluorine, present in the form of a single fluoroalkyl amino acid side chain in the P1 position of the well characterized serine-protease inhibitor BPTI, can fully restore inhibitor activity to a mutant that contains the corresponding hydrocarbon side chain at the same site. High resolution crystal structures were obtained for four BPTI variants in complex with bovine beta-trypsin, revealing changes in the stoichiometry and dynamics of water molecules in the S1 subsite. These results demonstrate that the introduction of fluorine into a protein environment can result in "chemical complementation" that has a significantly favorable impact on protein-protein interactions. PMID- 29449929 TI - Vibrational properties and bonding nature of Sb2Se3 and their implications for chalcogenide materials. AB - Antimony selenide (antimonselite, Sb2Se3) is a versatile functional material with emerging applications in solar cells. It also provides an intriguing prototype to study different modes of bonding in solid chalcogenides, all within one crystal structure. In this study, we unravel the complex bonding nature of crystalline Sb2Se3 by using an orbital-based descriptor (the crystal orbital Hamilton population, COHP) and by analysing phonon properties and interatomic force constants. We find particularly interesting behaviour for the medium-range Sb...Se contacts, which still contribute significant stabilisation but are much softer than the "traditional" covalent bonds. These results have implications for the assembly of Sb2Se3 nanostructures, and bond-projected force constants appear as a useful microscopic descriptor for investigating a larger number of chalcogenide functional materials in the future. PMID- 29449930 TI - Overcoming aggregation in indium salen catalysts for isoselective lactide polymerization. AB - A methodology for controlling aggregation in highly active and isoselective indium catalysts for the ring opening polymerization of racemic lactide is reported. A series of racemic and enantiopure dinuclear indium ethoxide complexes bearing salen ligands [(ONNOR)InOEt]2 (R = Br, Me, admantyl, cumyl, t-Bu) were synthesized and fully characterized. Mononuclear analogues (ONNOR)InOCH2Pyr (R = Br, t-Bu, SiPh3) were synthesized by controlling aggregation with the use of chelating 2-pyridinemethoxide functionality. The nuclearity of metal complexes was confirmed using PGSE NMR spectroscopy. Detailed kinetic studies show a clear initiation period for these dinuclear catalysts, which is lacking in their mononuclear analogues. The polymerization behavior of analogous dinuclear and mononuclear compounds is identical and consistent with a mononuclear propagating species. The isotacticity of the resulting polymers was investigated using direct integration and peak deconvolution methodologies and the two were compared. PMID- 29449931 TI - Coordination diversity in hydrogen-bonded homoleptic fluoride-alcohol complexes modulates reactivity. AB - The nucleophilic reactivity of fluoride ion is altered in the presence of hydrogen-bond donors, including alcohols. Relatively little is known about the coordination involved; to rectify this, the X-ray structures of fourteen novel fluoride-alcohol complexes with tetrabutylammonium as the counterion have been determined. The coordination number varies from two to four depending on the steric bulk of the alcohol and is closely linked to trends in reactivity. This diversity in coordination stoichiometry is unprecedented but significant, as it implies differences in the ability of the fluoride-alcohol complexes to dissociate in solution with release of a more active and/or selective fluoride source. PMID- 29449932 TI - Engineering beta-sheets employing N-methylated heterochiral amino acids. AB - There is a lack of functional group diversity in the reverse turn motifs nucleating a beta-sheet conformation in designed peptides, proteins and foldamers. The majority of these sequences consist of d-Pro-l-Pro, d-Pro-Gly or Asn-Gly as the turn inducing motif restricting their biological application and physicochemical modulation. In this report, for the first time we elucidate that N-methylation of heterochiral amino acids in linear peptides nucleates beta-sheet conformation without the necessity of having a ring or covalent constraint at the reverse turn. Our results show that d-Pro can be conveniently substituted by any other N-methylated d-amino acid followed by an N-methylated l-amino acid or sarcosine to adopt a betaII' turn inducing the beta-sheet folding. Furthermore, we reveal that a single amino acid either at the i + 1 or i + 2 site of the reverse turn can modulate the right-handed twist, which eventually dictates the extent of the foldedness of the beta-hairpin. PMID- 29449934 TI - A thin multifunctional coating on a separator improves the cyclability and safety of lithium sulfur batteries. AB - Lithium-sulfur batteries are one of the most promising next-generation batteries due to their high theoretical specific capacity, but are impeded by the low utilization of insulating sulfur, unstable morphology of the lithium metal anode, and transport of soluble polysulfides. Here, by coating a layer of nano titanium dioxide and carbon black onto a commercial polypropylene separator, we demonstrate a new composite separator that can confine the polysulfides on the cathode side, forming a catholyte chamber, and at the same time block the dendritic lithium on the anode side. Lithium-sulfur batteries using this separator show a high initial capacity of 1206 mA h g-1 and a low capacity decay rate of 0.1% per cycle at 0.5C. Analyses reveal the electrocatalytic effect and the excellent dendrite-blocking capability of the ~7 um thick coating. PMID- 29449933 TI - A simplified characterization of S-adenosyl-l-methionine-consuming enzymes with 1 Step EZ-MTase: a universal and straightforward coupled-assay for in vitro and in vivo setting. AB - Methyltransferases use S-adenosyl-l-methionine (SAM) to deposit methyl marks. Many of these epigenetic 'writers' are associated with gene regulation. As cancer etiology is highly correlated with misregulated methylation patterns, methyltransferases are emerging therapeutic targets. Successful assignment of methyltransferases' roles within intricate biological networks relies on (1) the access to enzyme mechanistic insights and (2) the efficient screening of chemical probes against these targets. To characterize methyltransferases in vitro and in vivo, we report a highly-sensitive one-step deaminase-linked continuous assay where the S-adenosyl-l-homocysteine (SAH) enzyme-product is rapidly and quantitatively catabolized to S-inosyl-l-homocysteine (SIH). To highlight the broad capabilities of this assay, we established enzymatic characteristics of two protein arginine methyltransferases (PRMT5 and PRMT7), a histone-lysine N methyltransferase (DIM-5) and a sarcosine/dimethylglycine N-methyltransferase (SDMT). Since the coupling deaminase TM0936 displays robust activity over a broad pH-range we determined the pH dependence of SDMT reaction rates. TM0936 reactions are monitored at 263 nm, so a drawback may arise when methyl acceptor substrates absorb within this UV-range. To overcome this limitation, we used an isosteric fluorescent SAM-analog: S-8-aza-adenosyl-l-methionine. Most enzymes tolerated this probe and sustained methyltransfers were efficiently monitored through loss of fluorescence at 360 nm. Unlike discontinuous radioactive- and antibody-based assays, our assay provides a simple, versatile and affordable approach towards the characterization of methyltransferases. Supported by three logs of linear dynamic range, the 1-Step EZ-MTase can detect methylation rates as low as 2 MUM h 1, thus making it possible to quantify low nanomolar concentrations of glycine N methyltransferase within crude biological samples. With Z'-factors above 0.75, this assay is well suited to high-throughput screening and may promote the identification of novel therapeutics. PMID- 29449935 TI - Pleomorphic liposarcoma of bone: a rare primary malignant bone tumour. AB - Background: Liposarcoma is an extremely rare primary bone sarcoma. Case presentation: We report a case of primary pleomorphic liposarcoma that arose in an 18 year old male in the metaphysis of the left tibia. Plain radiographs showed a partly sclerotic lesion and MR imaging a heterogeneous tumour predominantly isointense on T1- and high-signal on T2-weighted sequences with focal areas of increased T1 signal that suppressed with fat saturation. PET/CT showed marked FDG uptake (SUV = 17.1) in the primary tumour as well as a metastasis in the right distal femur and multiple small pulmonary metastases. Histologically, the tumour was a pleomorphic liposarcoma containing large tumour cells with vacuolated cytoplasm and hyperchromatic pleomorphic nuclei as well as numerous lipoblasts and scattered brown fat-like cells. Tumour cells strongly expressed FABP4/aP2, a marker of adipocyte differentiation, and UCP1, a marker of brown fat, but not S100. The case was treated with neoadjuvant MAP chemotherapy, resulting in extensive (> 95%) necrosis in the primary tumour and almost complete resolution of the femoral and pulmonary metastases. Conclusions: Pleomorphic liposarcoma can present as a sclerotic primary malignant bone tumour; markers of adipose differentiation are useful in histological diagnosis and neoadjuvant MAP chemotherapy results in significant tumor necrosis.

AB - Background: The pathways of thermal instability of amino acids have been unknown. New mass spectrometric data allow unequivocal quantitative identification of the decomposition products. Results: Calorimetry, thermogravimetry and mass spectrometry were used to follow the thermal decomposition of the eight amino acids G, C, D, N, E, Q, R and H between 185 degrees C and 280 degrees C. Endothermic heats of decomposition between 72 and 151 kJ/mol are needed to form 12 to 70% volatile products. This process is neither melting nor sublimation. With exception of cysteine they emit mainly H2O, some NH3 and no CO2. Cysteine produces CO2 and little else. The reactions are described by polynomials, AA->a NH3+b H2O+c CO2+d H2S+e residue, with integer or half integer coefficients. The solid monomolecular residues are rich in peptide bonds. Conclusions: Eight of the 20 standard amino acids decompose at well-defined, characteristic temperatures, in contrast to commonly accepted knowledge. Products of decomposition are simple. The novel quantitative results emphasize the impact of water and cyclic condensates with peptide bonds and put constraints on hypotheses of the origin, state and stability of amino acids in the range between 200 degrees C and 300 degrees C. PMID- 29449936 TI - Function of aquaporins in sepsis: a systematic review. AB - Background: Sepsis is a common cause of death in intensive care units worldwide. Due to the high complexity of this immunological syndrome development of novel therapeutic strategies is urgent. Promising drug targets or biomarkers may depict aquaporins (AQPs) as they regulate crucial key mechanisms of sepsis. Main body: Here we report on base of the current literature that several AQPs are involved in different physiological processes of sepsis. In immune system mainly AQPs 3, 5 and 9 seem to be important, as they regulate the migration of different immune cells. Several studies showed that AQP3 is essential for T cell function and macrophage migration and that AQP5 and AQP9 regulate neutrophil cell migration and impact sepsis survival. Additionally, to the function in immune system AQPs 1 and 5 play a role in sepsis induced lung injury and their downregulation after inflammatory stimuli impair lung injury. By contrast, AQP4 expression is up regulated during brain inflammation and aggravates brain edema in sepsis. In kidney AQP2 expression is downregulated during sepsis and can cause renal failure. Some studies also suggest a role of AQP1 in cardiac function. Conclusion: In conclusion, AQPs are involved in many physiological dysfunctions in sepsis and their expressions are differently regulated. Additional research on the regulatory mechanisms of aquaporins may identify potential therapeutic targets. PMID- 29449939 TI - Innovative approaches to genome editing in avian species. AB - The tools available for genome engineering have significantly improved over the last 5 years, allowing scientist to make precise edits to the genome. Along with the development of these new genome editing tools has come advancements in technologies used to deliver them. In mammals genome engineering tools are typically delivered into in vitro fertilized single cell embryos which are subsequently cultured and then implanted into a recipient animal. In avian species this is not possible, so other methods have been developed for genome engineering in birds. The most common involves in vitro culturing of primordial germ cells (PGCs), which are cells that migrate through the embryonic circulatory system to the developing gonad and colonize the gonad, eventually differentiating into the gonadocytes which produce either sperm or ova. While in culture the PGCs can be modified to carry novel transgenes or gene edits, the population can be screened and enriched, and then transferred into a recipient embryo. The largest drawback of PGC culture is that culture methods do not transfer well across avian species, thus there are reliable culture methods for only a few species including the chicken. Two newer technologies that appear to be more easily adapted in a wider range of avian species are direct injection and sperm transfection assisted gene editing (STAGE). The direct injection method involves injecting genome engineering tools into the circulatory system of the developing embryo just prior to the developmental time point when the PGCs are migrating to the gonads. The genome engineering tools are complexed with transfection reagents, allowing for in vivo transfection of the PGCs. STAGE utilizes sperm transfection to deliver genome engineering tools directly to the newly fertilized embryo. Preliminary evidence indicates that both methodologies have the potential to be adapted for use in birds species other than the chicken, however further work is needed in this area. PMID- 29449938 TI - Molecular characteristics and successful management of a respiratory syncytial virus outbreak among pediatric patients with hemato-oncological disease. AB - Background: Respiratory syncytial virus (RSV) is responsible for upper and lower respiratory tract infection in adults and children. Especially immunocompromised patients are at high risk for a severe course of infection, and mortality is increased. Moreover RSV can spread in healthcare settings and can cause outbreaks. Herein we demonstrate the successful control and characteristics of a RSV outbreak that included 8 patients in our Department of Pediatric Hematology and Oncology. Methods: We performed an epidemiologic investigation and a molecular analysis of the outbreak strains. Moreover we present the outbreak control bundle and our concept for RSV screening in the winter season. Results: RSV A and B strains caused the outbreak. RSV B strains affected 3 patients, 2 of whom were co-infected with RSV A. Exactly this RSV A strain was detected in another 5 patients. Our multimodal infection control bundle including prophylactic RSV screening was able to rapidly stop the outbreak. Conclusion: An infection control bundle in RSV outbreaks should address all potential transmission pathways. In pediatric settings the restriction of social activities might have a temporal negative impact on quality of life but helps to limit transmission opportunities. Molecular analysis allows better understanding of RSV outbreaks and, if done in a timely manner, might be helpful for guidance of infection control measures. PMID- 29449940 TI - Effects of fumaric acid supplementation on methane production and rumen fermentation in goats fed diets varying in forage and concentrate particle size. AB - Background: In rumen fermentation, fumaric acid (FA) could competitively utilize hydrogen with methanogenesis to enhance propionate production and suppress methane emission, but both effects were diet-dependent. This study aimed to explore the effects of FA supplementation on methanogenesis and rumen fermentation in goats fed diets varying in forage and concentrate particle size. Methods: Four rumen-cannulated goats were used in a 4 * 4 Latin square design with a 2 * 2 factorial arrangement of treatments: low or high ratio of forage particle size: concentrate particle size (Fps:Cps), without or with FA supplementation (24 g/d). Fps:Cps was higher in the diet with chopped alfalfa hay plus ground corn than in that with ground alfalfa hay plus crushed corn. Results: Both increasing dietary Fps:Cps and FA supplementation shifted ruminal volatile fatty acid (VFA) patterns toward more propionate and less acetate in goats. An interaction between dietary Fps:Cps and FA supplementation was observed for the ratio of acetate to propionate (A:P), which was more predominant when FA was supplemented in the low-Fps:Cps diet. Methane production was reduced by FA, and the reduction was larger in the low-Fps:Cps diet (31.72%) than in the high Fps:Cps diet (17.91%). Fumaric acid decreased ruminal total VFA concentration and increased ruminal pH. No difference was found in ruminal DM degradation of concentrate or alfalfa hay by dietary Fps:Cps or FA. Goats presented a lower ruminal methanogen abundance with FA supplementation and a higher B. fibrisolvens abundance with high dietary Fps:Cps. Conclusions: Adjusting dietary Fps:Cps is an alternative dietary model for studying diet-dependent effects without changing dietary chemical composition. Fumaric acid supplementation in the low-Fps:Cps diet showed greater responses in methane mitigation and propionate increase. PMID- 29449941 TI - Cardiovascular risk factor burden in Africa and the Middle East across country income categories: a post hoc analysis of the cross-sectional Africa Middle East Cardiovascular Epidemiological (ACE) study. AB - Background: A significant number of cardiovascular disease (CVD)-related deaths occur in developing countries. An increasing prevalence of CVD is associated with a change in the macro-economy of these countries. In this post hoc analysis, CVD risk factor (CVDRF) prevalence is evaluated across countries based on national income in the Africa and Middle East Region (AfME). Methods: Data from the Africa Middle East Cardiovascular Epidemiological (ACE) study were used; a cross sectional study in 14 AfME countries (94 clinics) from July 2011-April 2012, which evaluated CVDRF prevalence in stable adult outpatients. World Bank definitions were used to classify countries as low-income (LI), lower-middle income (LMI), upper-middle-income (UMI) or high-income (HI) countries. Four thousand three hundred seventy-eight subjects were recruited where 260 (6%), 1324 (30%), 1509 (35%) and 1285 (29%) were from LI, LMI, UMI, and HI countries, respectively. Results: Of all the CVDRFs evaluated, almost two-thirds of the study population across the national income groups had abdominal obesity and dyslipidemia. Countries in the HI category were associated with a higher prevalence of diabetes (32%), obesity (44%) and smoking (16%). UMI and HI countries were associated with higher clustering of CVDRFs where at least one third of subjects having four or more CVDRFs. Lower income countries had lower blood pressure control rates and lower percentages of outpatients achieving LDL cholesterol targets. Conclusion: The burden of CVDRFs in stable outpatients is high across the national income categories in the AfME region, with HI countries showing a higher prevalence of CVDRFs. The high burden in lower income countries is associated with sub-optimal control of dyslipidemia and hypertension. Lowering the CVDRF burden would need specific public health actions in line with positive changes in the macro-economy of these countries. Trial registration: The ACE trial is registered under NCT01243138. PMID- 29449942 TI - Epidemic potential by sexual activity distributions. AB - For sexually transmitted infections like HIV to propagate through a population, there must be a path linking susceptible cases to currently infectious cases. The existence of such paths depends in part on the degree distribution. Here, we use simulation methods to examine how two features of the degree distribution affect network connectivity: Mean degree captures a volume dimension, while the skewness of the upper tail captures a shape dimension. We find a clear interaction between shape and volume: When mean degree is low, connectivity is greater for long tailed distributions, but at higher mean degree, connectivity is greater in short tailed distributions. The phase transition to a giant component and giant bicomponent emerges as a positive function of volume, but it rises more sharply and ultimately reaches more people in short-tail distributions than in long-tail distributions. These findings suggest that any interventions should be attuned to how practices affect both the volume and shape of the degree distribution, noting potential unanticipated effects. For example, policies that primarily affect high volume nodes may not be effective if they simply redistribute volume among lower degree actors, which appears to exacerbate underlying network connectivity. PMID- 29449943 TI - Aging-like physiological changes in the skin of Japanese obese diabetic patients. AB - Objective: Obesity-associated diabetes causes aging-like changes to skin physiology in animal models, but there have been no clinical studies focusing on human obese diabetic patients. The purpose of this study was to examine the hypothesis that obesity-associated diabetes accelerates aging-like skin changes in Japanese people. Methods: This cross-sectional study enrolled obese-diabetes patients (body mass index >= 25 kg m-2) and healthy volunteers (body mass index < 25 kg m-2) as controls. Skin physiology parameters relating to aging (stratum corneum hydration, transepidermal water loss, skin pH, advanced glycation end products, and dermal collagen density) were evaluated in the two groups. Results: About 37 subjects participated (16 in a control group and 21 in an obese-diabetes group). Age was not significantly different between the groups. The stratum corneum hydration level was significantly lower in the obese-diabetes group. Transepidermal water loss and levels of advanced glycation end-products were significantly higher in this group. Skin pH was not significantly different between groups. Dermal collagen density decreased in the obese-diabetes group. Conclusion: We showed that obese-diabetes patients have decreased stratum corneum hydration, increased transepidermal water loss, higher skin advanced glycation end-products and decreased dermal collagen fiber density compared with normal weight subjects. These results indicate that the ordinary age-related physiological skin changes seen in the elderly can also occur in obese-diabetes patients aged in their 40s. PMID- 29449944 TI - Dexmedetomidine use during epiduroscopy reduces fentanyl use and postoperative nausea and vomiting: A single-center retrospective study. AB - Objectives: Minimally invasive epiduroscopy has recently been reported as an effective treatment procedure for chronic and intractable low back pain. However, no study has determined safe anesthetics for monitored anesthesia care during epiduroscopy. We aimed to compare and evaluate conventional monitored anesthesia care drugs with dexmedetomidine. Methods: A retrospective study including all patients who underwent epiduroscopy at the JR Tokyo General Hospital from April 2011 to March 2016 was designed. The epiduroscopy procedures were performed under anesthesia with dexmedetomidine plus fentanyl (dexmedetomidine group) or droperidol plus fentanyl (neuroleptanalgesia group). Patients who received analgesics other than fentanyl, another analgesic combined with fentanyl, any sedative other than dexmedetomidine or droperidol, or who had incomplete data were excluded. We compared (1) the type and dose of medication during the epiduroscopy and (2) the incidence of postoperative nausea and vomiting. Results: We identified 45 patients (31 and 14 in the dexmedetomidine and neuroleptanalgesia groups, respectively) with a mean age of 69.0 years. The two groups had comparable characteristics, such as age, sex, body mass index, the American Society of Anesthesiologists Physical Status, analgesics used in the clinic, comorbidities, history of smoking, and the duration of anesthesia. The dexmedetomidine group received a significantly lower fentanyl dose during surgery (126 +/- 14 vs 193 +/- 21 ug, mean +/- standard deviation, p = 0.014) and exhibited a significantly lower incidence of postoperative nausea and vomiting (1 vs 3, p = 0.047) than the neuroleptanalgesia group. Conclusion: This study involved elderly patients, and the use of dexmedetomidine in monitored anesthesia care during epiduroscopy procedures in these patients may reduce the required fentanyl dose during surgery and the incidence of postoperative nausea and vomiting. This strategy may help prevent respiratory depression and aspiration. PMID- 29449945 TI - Psychosocial factors associated with change in pain and disability outcomes in chronic low back pain patients treated by physiotherapist: A systematic review. AB - Background: Almost 80% of people have low back pain at least once in their life. Clinical guidelines emphasize the use of conservative physiotherapy and the importance of staying active. While the psychological factors predicting poor recovery following surgical intervention are understood, the psychosocial factors associated with poor outcomes following physiotherapy have yet to be identified. Methods: Electronic searches of PubMed, Medline, CINAHL, PsycINFO and EBSCO were conducted using terms relating to psychosocial factors, chronic low back pain, disability and physiotherapy. Papers examining the relationship between psychosocial factors and pain and disability outcomes following physiotherapy were included. Two reviewers selected, appraised and extracted studies independently. Results: In total, 10 observational studies were identified that suggested an association between fear of movement, depression, self-efficacy and catastrophizing in modifying pain and disability outcomes following physiotherapy. Discussion: Although limited by methodological shortcomings of included studies, and heterogeneity of physiotherapy interventions and measures of disability and psychosocial outcomes, the findings are consistent with other research in the context of back pain and physiotherapy, which suggest an association between psychosocial factors, including fear of movement, catastrophizing and self-efficacy and pain and disability outcomes in chronic low back pain patients treated by physiotherapist. However, a direct relationship cannot be concluded from this study. Conclusion: Findings suggest an association between psychosocial factors, including fear of movement, catastrophizing and self-efficacy and pain and disability outcomes in chronic low back pain patients treated by physiotherapist, which warrants further study. PMID- 29449946 TI - Prescriber continuity and medication availability in older adults with cardiometabolic conditions. AB - Background: Many older adults have multiple conditions and see multiple providers, which may impact their use of essential medications. Objective: We examined whether the number of prescribers of these medications was associated with the availability of medications, a surrogate for adherence, to manage diabetes, hypertension or dyslipidemia. Methods: A retrospective cohort of 383,145 older adults with diabetes, hypertension or dyslipidemia in the US Medicare program living in 10 states. The association between the number of prescribers of cardiometabolic medications in 2010 and medication availability (proportion of days with medication on hand) in 2011 was estimated via logistic regression, controlling for patient demographic characteristics and chronic conditions. Results: Medicare beneficiaries with diabetes, hypertension and/or dyslipidemia had an average of five chronic conditions overall, obtained 10-12 medications for all conditions and most often had one prescriber of cardiometabolic medications. In adjusted analyses, the number of prescribers was not significantly associated with availability of oral diabetes agents but having more prescribers is associated with increased medication availability in older Medicare beneficiaries with dyslipidemia or hypertension. Conclusion: The incremental addition of new prescribers may be clinically reasonable for complex patients but creates the potential for coordination problems and informational discontinuity over time. Health systems may want to identify complex patients with multiple prescribers to minimize care fragmentation. PMID- 29449947 TI - Reversible platypnoea-orthodeoxia syndrome in post-tuberculosis bronchial stenosis. AB - Bronchial stenosis is known to complicate endobronchial tuberculosis despite medical therapy. It is often associated with dyspnoea. In severe cases, bronchial stenosis results in airflow obstruction, impaired secretion clearance, and can lead to respiratory failure. We present an unusual observation of platypnoea orthodeoxia syndrome in a young woman with acute atelectasis due to post tuberculosis bronchial stricture. Imaging revealed complete middle and right lower lobe atelectasis with a partially aerated right upper lobe. In the sitting posture, there was positional worsening of dyspnoea associated with an increase in the alveolar-arterial oxygen gradient and shunt fraction. The likely mechanism was due to gravitational difference in ventilation-perfusion matching. The platypnoea-orthodeoxia syndrome was reversible following balloon dilatation of the bronchial stenosis and expansion of the collapsed lung. PMID- 29449948 TI - Physical activity and sedentary behavior following pediatric burns - a preliminary investigation using objective activity monitoring. AB - Background: Adequate levels of regular physical activity (PA) are crucial for health and well-being. Pediatric burn injuries can have major physiological consequences in both the short and long term. The question is whether these consequences affect post burn PA levels. This study therefore aimed to describe PA and sedentary behavior (SB) in children and adolescents 1-5 years after burn injury. Methods: Daily PA and SB were monitored in 20 children and adolescents (12 boys and 8 girls, aged 6-17 years, with burns covering 10-37% of total body surface area, 1-5 years post burn) for 1 week using the ActiGraph GTX3+ accelerometer. Activity counts were categorized into SB, light PA, moderate PA, vigorous PA, moderate-to-vigorous PA (MVPA), and total PA. Outcomes were compared with non-burned reference values and PA levels recommended by the World Health Organization (WHO). Results: The participants spent about 5.1 h per day on total PA and 7.4 h on SB. Most of the active time (~ 83%) was categorized as light PA. Thirty-five percent of the group, especially the young boys, spent on average >= 60 min on MVPA per day. The boys, although with large interindividual differences, spent more time on MVPA than the girls (p < .005). Older age was associated with less PA time, while more time was spent sedentary. No trends were found indicating an effect of burn characteristics, time post burn, or length of hospital stay, and no differences were found with non-burned peers. Conclusion: Duration and intensity of PA and SB in children and adolescents 1-5 years after burn injury were similar to non-burned peers. However, only 35% of the group met the WHO physical activity recommendation. Given the increased long term risk for physical conditions following pediatric burns, physical activity should be encouraged in this vulnerable population. Trial registration: The study is registered in the National Academic Research and Collaborations Information System of the Netherlands (OND1348800).

PMID- 29449950 TI - Impact of malnutrition on survival and healthcare utilization in Medicare beneficiaries with diabetes: a retrospective cohort analysis. AB - Objective: The aim of this study was to examine the impact of pre-existing malnutrition on survival and economic implications in elderly patients with diabetes. Research design and methods: A retrospective observational study was conducted to examine the impact of malnutrition with or without other significant health conditions on survival time and healthcare costs using the Centers for Medicare and Medicaid Services (CMS) data from 1999 to 2014 for beneficiaries with a confirmed first date of initial diagnosis of diabetes (n=15 121 131). The primary outcome was survival time, which was analyzed using all available data and after propensity score matching. Healthcare utilization cost was a secondary outcome. Results: A total of 801 272 beneficiaries were diagnosed with malnutrition. The analysis on propensity score-matched data for the effect of common conditions on survival showed that the risk for death in beneficiaries with diabetes increased by 69% in malnourished versus normo-nourished (HR, 1.69; 99.9% CI 1.64 to 1.75; P<0.0001) beneficiaries. Malnutrition increased the risk for death within each of the common comorbid conditions including ischemic heart disease (1.63; 1.58 to 1.68), chronic obstructive pulmonary disorder (1.60; 1.55 to 1.65), stroke or transient ischemic attack (1.57; 1.53 to 1.62), heart failure (1.54; 1.50 to 1.59), chronic kidney disease (1.50; 1.46 to 1.55), and acute myocardial infarction (1.47; 1.43 to 1.52). In addition, the annual total spending for the malnourished beneficiaries was significantly greater than that for the normo-nourished beneficiaries ($36 079 vs 20 787; P<0.0001). Conclusions: Malnutrition is a significant comorbidity affecting survival and healthcare costs in CMS beneficiaries with diabetes. Evidence-based clinical decision pathways need to be developed and implemented for appropriate screening, assessment, diagnosis and treatment of malnourished patients, and to prevent malnutrition in normo-nourished patients with diabetes. PMID- 29449951 TI - Glucagon-like peptide-1 receptor agonists are not associated with retinal adverse events in the FDA Adverse Event Reporting System. AB - Objectives: Glucagon-like peptide-1 receptor agonists (GLP-1RA) are widely used for the treatment of type 2 diabetes. In large trials, the GLP-1RAs liraglutide and semaglutide improved cardiovascular outcomes, but semaglutide was associated with an increased risk of retinopathy progression. We herein evaluated the association between GLP-1RA and retinal adverse events (AE) in the Food and Drug Administration Adverse Event Reporting System (FAERS). Research design and methods: We mined the FAERS between 2004q1 and 2017q1 (for a total of 9 217 555 AE reports) to analyze disproportionality and evaluate the association between GLP-1RAs and AEs involving the retina. We compared the frequency of retinal AEs among reports including GLP-1RAs and in those including other glucose-lowering medications (GLMs) as suspect or concomitant drugs. Results: We retrieved 114 814 reports involving GLP-1RA and 694 725 reports involving other GLMs as suspect or concomitant drugs. The cumulative frequency of retinal AEs was 2.53/1000 for reports involving GLP-1RA vs 6.62/1000 for reports involving other GLMs, with a proportional reporting ratio of 0.38 (95% CI 0.34 to 0.43; P<0.0001). Reports involving GLP-1RAs listed significantly more comorbid conditions and concomitant medications. Findings were consistent after filtering the diabetes indication irrespective of concomitant GLM, in reports including and in those not including insulin, and for the various GLP-1RAs. Conclusions: In the FAERS there is no evidence that GLP-1RAs are associated with AEs suggestive of retinopathy progression. Despite more comorbid conditions and concomitant medications, in reports with GLP-1RA the frequency of retinal AEs was significantly lower than in reports with other GLMs. PMID- 29449952 TI - Variations of dietary intake by glycemic status and Hispanic/Latino heritage in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL). AB - Objective: A healthy diet is important for diabetes prevention and control; however, few studies have assessed dietary intake among US Hispanics/Latinos, a diverse population with a significant burden of diabetes. To address this gap in the literature, we determined intake of energy, macro/micronutrients, and vitamin supplements among Hispanics/Latinos by glycemic status and heritage. Research design and methods: Cross-sectional study of adults aged 18-74 years from the Hispanic Community Health Study/Study of Latinos (2008-2011) with complete baseline data on glycemic status and two 24-hour dietary recalls (n=13 089). Age adjusted and sex-adjusted and multivariable-adjusted measures of intake were determined by glycemic status and heritage. Results: Mean age-adjusted and sex adjusted energy intake was significantly lower among Hispanics/Latinos with diagnosed diabetes compared with those with normal glycemic status (1665 vs 1873 kcal, P<0.001). Fiber intake was higher among those with diagnosed diabetes versus normal glycemic status (P<0.01). Among those with diagnosed diabetes, energy intake was highest among those with Cuban heritage compared with most other heritage groups (P<0.01 for all, except Mexicans), but there was no difference after additional adjustment. Fiber intake was significantly lower for those of Cuban heritage (vs Dominican, Central American, and Mexican), and sodium intake was significantly higher (vs all other heritage groups) (P<0.01 for all); findings were null after additional adjustment. There was no difference in supplemental intake of vitamin D, calcium, magnesium, or potassium by glycemic status. Conclusions: As part of the care of Hispanics/Latinos with diabetes, attention should be made to fiber and sodium consumption. PMID- 29449953 TI - Informing the development of online weight management interventions: a qualitative investigation of primary care patient perceptions. AB - Background: The internet is a potentially promising medium for delivering weight loss interventions. The current study sought to explore factors that might influence primary care patients' initial uptake and continued use (up to four weeks) of such programmes to help inform the development of novel, or refinement of existing, weight management interventions. Methods: Semi-structured interviews were conducted with 20 patients purposively sampled based on age, gender and BMI from a single rural general practice. The interviews were conducted 4 weeks after recruitment at the general practice and focused on experiences with using one of three freely available weight loss websites. Thematic Analysis was used to analyse the data. Results: Findings suggested that patients were initially motivated to engage with internet-based weight loss programmes by their accessibility and novelty. However, continued use was influenced by substantial facilitators and barriers, such as time and effort involved, reaction to prompts/reminders, and usefulness of information. Facilitation by face-to-face consultations with the GP was reported to be helpful in supporting change. Conclusions: Although primary care patients may not be ready yet to solely depend on online interventions for weight loss, their willingness to use them shows potential for use alongside face-to-face weight management advice or intervention. Recommendations to minimise barriers to engagement are provided. PMID- 29449954 TI - Metabotropic glutamate receptor 5 tracer [18F]-FPEB displays increased binding potential in postcentral gyrus and cerebellum of male individuals with autism: a pilot PET study. AB - Background: Autism is a neurodevelopmental disorder that is first manifested during early childhood. Postmortem experiments have identified significantly elevated expression of metabotropic glutamate receptor 5 (mGluR5) in cerebellar vermis and prefrontal cortex of individuals with autism. Methods: In the current study we employed the mGluR5 tracer [18F]-3-fluoro-5-[(pyridin-3 yl)ethynyl]benzonitrile ([18F]-FPEB) to quantify mGluR5 binding in vivo in adults with autism vs. healthy controls using positron emission tomography (PET). Results: We identified significantly higher [18F]-FPEB binding potential in the postcentral gyrus and cerebellum of individuals with autism. There was a significant negative correlation between age and [18F]-FPEB binding potential in the cerebellum but not in the postcentral gyrus. In the precuneus, [18F]-FPEB binding potential correlated positively with the lethargy subscale score for the Aberrant Behavioral Checklist (ABC). In cerebellum, there were significant negative correlations between [18F]-FPEB binding potential and ABC total score, ABC hyperactivity subscale score, and the ABC inappropriate speech subscale score. Conclusions: These novel findings demonstrate for the first time that mGluR5 binding is altered in critical brain areas of subjects with autism, suggesting abnormal glutamate signaling in these regions. Finally, the correlations between altered [18F]-FPEB binding potential in the cerebellum and precuneus suggest that some autistic symptoms may be influenced by abnormal glutamate signaling. PMID- 29449956 TI - Bilateral bronchial stent deployment for palliative treatment of a compressive intrathoracic mass in a cat. AB - Case summary: Bronchial stents may be useful to relieve clinical signs of extraluminal compression. Herein we describe a case which, to our knowledge, is the first cat where bilateral bronchial stents have been used clinically. Respiratory signs of principal bronchial compression were alleviated after the stent procedure. Minor complications occurred, specifically: severe hypoxia during stent deployment; a transient, self-limiting postoperative pneumothorax possibly associated with ventilation-induced lung injury; bronchopneumonia (possibly pre-existing); and transient worsening of cough postoperatively. Stents were well- tolerated long- term. The cat was euthanased at 44 weeks post-stent procedure, owing to clinical signs of regurgitation, seemingly related to oesophageal dysfunction associated with tumour invasion. Relevance and novel information: In this case, it appeared that bronchial stents were feasible and the procedure was associated with long-term improvement in respiratory signs related to extraluminal bronchial compression. PMID- 29449955 TI - Prospects for Precision Medicine in Glomerulonephritis Treatment. AB - Background: Glomerulonephritis (GN) consists of a group of kidney diseases that are categorized based on shared histopathological features. The current classifications for GN make it difficult to distinguish the individual variability in presentation, disease progression, and response to treatment. GN is a significant cause of end-stage renal disease (ESRD), and improved therapies are desperately needed because current immunosuppressive therapies sometimes lack efficacy and can lead to significant toxicities. In recent years, the combination of high-throughput genetic approaches and technological advances has identified important regulators contributing to GN. Objectives: In this review, we summarize recent findings in podocyte biology and advances in experimental approaches that have opened the possibility of precision medicine in GN treatment. We provide an integrative basic science and clinical overview of new developments in GN research and the discovery of potential candidates for targeted therapies in GN. Findings: Advances in podocyte biology have identified many candidates for therapeutic targets and potential biomarkers of glomerular disease. The goal of precision medicine in GN is now being pursued with recent technological improvements in genetics, accessibility of biologic and clinical information with tissue biobanks, high-throughput analysis of large-scale data sets, and new human model systems such as kidney organoids. Conclusion: With advances in data collection, technologies, and experimental model systems, we now have vast tools available to pursue precision medicine in GN. We anticipate a growing number of studies integrating data from high-throughput analysis with the development of diagnostic tools and targeted therapies for GN in the near future.

AB - Case summary: A 5-month-old intact female Scottish Fold cat was presented for cardiac evaluation. Careful auscultation detected a slight systolic murmur (Levine I/VI). The findings of electrocardiography, thoracic radiography, non invasive blood pressure measurements and conventional echocardiographic studies were unremarkable. However, two-dimensional speckle tracking echocardiography revealed abnormalities in myocardial deformations, including decreased early-to late diastolic strain rate ratios in longitudinal, radial and circumferential directions, and deteriorated segmental systolic longitudinal strain. At the follow-up examinations, the cat exhibited echocardiographic left ventricular hypertrophy and was diagnosed with hypertrophic cardiomyopathy using conventional echocardiography. Relevance and novel information: This is the first report on the use of two-dimensional speckle tracking echocardiography for the early detection of myocardial dysfunction in a cat with hypertrophic cardiomyopathy; the myocardial dysfunction was detected before the development of hypertrophy. The findings from this case suggest that two-dimensional speckle tracking echocardiography can be useful for myocardial assessment when conventional echocardiographic and Doppler findings are ambiguous.

AB - Background: Rates of participation in Diabetes Prevention Programs (DPPs) are low. This may be due, in part, to low levels of autonomous motivation (i.e., motivation that arises from internal sources and sustains healthy behaviors over time) to prevent type 2 diabetes (T2DM) among many individuals with prediabetes. Mobile health (mHealth) technologies that incorporate principles from the Self Determination Theory offer an effective and scalable approach to increase autonomous motivation levels. One promising mobile phone-based application is JOOL Health, which aims to help users connect certain health behaviors (e.g., sleep and diet) with personal values in specific life domains (e.g., family and work). The first aim of this study is to estimate whether JOOL Health can increase autonomous motivation to prevent T2DM among individuals with prediabetes who declined DPP participation. The second aim of this pilot study is to examine the intervention's feasibility and acceptability. Methods: This is a 12-week, three-arm pilot randomized controlled trial. We will recruit 105 individuals with prediabetes who did not engage in a DPP despite invitation from their health plan to participate in face-to-face or web-based programs at no out-of-pocket-cost. Participants will be randomized to one of three study arms: (1) a group that receives information on prediabetes, evidence-based strategies to decrease progression to T2DM, and a list of resources for mHealth tools for monitoring diet, physical activity, and weight (comparison group); (2) a group that receives the JOOL Health application; and (3) a group that receives the JOOL Health application as well as a Fitbit activity tracker and wireless-enabled scale. Our primary outcome is change in autonomous motivation to prevent T2DM (measured using the Treatment Self-Regulation Questionnaire). We will also collect data related to the intervention's feasibility (recruitment and retention rates) and acceptability (adherence and qualitative experience) as well as changes in psychosocial outcomes, hemoglobin A1c, and weight. Discussion: To our knowledge, this is the first study that aims to promote positive health behaviors among individuals with prediabetes who previously declined to participate in a DPP. Our results will inform a larger trial to test the effect of JOOL Health on clinically relevant outcomes, including weight loss, physical activity, and DPP engagement.

AB - Background: Zwitterionic molecules have been widely studied as coating materials for preparing anti-fouling surfaces because they possess strong hydration properties that can resist non-specific protein adsorption. Numerous studies on surface modification using zwitterionic molecules have been investigated, such as electrochemically mediated and photoinitiated radical polymerization. However, these methods have some limitations, including multi-step process, difficulties in producing thick and dense layers as well as the requirement of extra facilities. In this study, we report a novel zwitterionic hydrogel-coating method via Fenton reaction for the preparation of anti-fouling surfaces. Methods: Sulfobetaine methacrylate (SBMA) hydrogel was coated on polyurethane (PU) by polymerization of SBMA molecules via the Fenton reaction. The coated surfaces were characterized by the measurements of water contact angle, SEM and XPS. The anti-fouling properties of the modified surfaces were evaluated by reductions of fibrinogen absorption and cell (human dermal fibroblasts, hDFBs) adhesion. Results: SBMA hydrogel layers were coated on the PU substrates and these layers have a high affinity for water. The hydrogel coatings were highly stable for 7 days, without a significant change in surface wettability. Importantly, the hydrogel-coated PU substrates decrease 80% of surface-adsorbed fibrinogen and surface-attached hDFBs (compared with uncoated PU substrates), indicating the excellent anti-fouling activities of modified surfaces. Conclusions: The hydrogel coated PU surfaces prepared by Fenton reaction with anti-fouling properties could have potential uses for implantable biomedical devices. PMID- 29449962 TI - Patient and public involvement in reducing health and care research waste. AB - Plain English summary: As much as 85 % of health research is believed to be wasted because it is not published or reported, the design is poor or does not consider what is already known in the topic area. Although a great deal of work has been done in the UK to reduce research waste, the role of patients and the public has not been discussed.This paper describes a survey, on the role of patients in reducing research waste, which was carried out as part of a larger piece of work on reducing waste in healthcare. The study found that patients were interested in reducing research waste. The key roles they play in research, for example being co-applicants for funding, members of project teams, co researchers, means they have some shared responsibility for making sure the quality of research is high. This includes finding out what is already known about a topic and getting the study design right before seeking funding, publishing and reporting the results when the study is finished. Recognising where waste happens is part of good management of a research study. Abstract: Background Eighty five per cent of health research expenditure is potentially wasted due to failure to publish research, unclear reporting of research that is published, and the failure of new research studies to systematically review previous research in the same topic area, poor study design and conduct. A great deal of progress has been made to address this issue but the role of patients and the public has not been considered.Main A small survey was undertaken, as part of a larger programme of work on reducing health and care waste, to understand the role of patients in reducing research waste. The study showed that patients are interested in this issue particularly in relation to the prioritisation of research and patient and public involvement.Conclusions Patients undertake key roles in the research process including co-applicancy, project management, or as co-researchers. This brings responsibility for ensuring high quality research and value for money. Responsibility for recognition of the potential for wasteful practices is part of the conduct and operation of research studies. PMID- 29449960 TI - Physician-initiated clinical study of limb ulcers treated with a functional peptide, SR-0379: from discovery to a randomized, double-blind, placebo controlled trial. AB - SR-0379 is a functional peptide that has wound healing effect with anti-microbial action, making it an ideal drug to prevent infection. To evaluate the safety, efficacy, and pharmacokinetics of SR-0379 for the treatment of leg ulcers, a physician-initiated, phase I/IIa, first-in-patient clinical study was designed. A multi-center, double-blind, randomized clinical study was conducted from October 2015 to September 2016. The inclusion criteria for leg ulcers were (1) diabetes or critical limb ischemia and (2) wound size <6 cm in diameter. Twelve patients were randomized into four groups and administered 0.02%, 0.1%, or 0.5% SR-0379 or placebo treatment on skin ulcers once per day for 28 days. Efficiency was evaluated by determining the rate of wound size reduction as a primary endpoint at 4 weeks after the first treatment compared with the pre-treatment wound size. As a secondary endpoint, the DESIGN-R score index, time to wound closure, and the 50% wound size reduction ratio were also evaluated. The safety of SR-0379 was evaluated during the study period. In the evaluation of efficiency, the skin ulcer reduction rates at the last evaluation were 44.73% for the 0.02% SR-0379 group, 68.25% for the 0.1% group, and 71.61% for the 0.5% group, compared with 9.95% for the placebo group. Six adverse events were reported in four patients, of which one occurred in the placebo group, and causal relationships to study drugs were denied for all six events. Treatment with SR-0379 for chronic leg ulcers was safe, well tolerated, and effective. PMID- 29449961 TI - Cadherin-26 (CDH26) regulates airway epithelial cell cytoskeletal structure and polarity. AB - Polarization of the airway epithelial cells (AECs) in the airway lumen is critical to the proper function of the mucociliary escalator and maintenance of lung health, but the cellular requirements for polarization of AECs are poorly understood. Using human AECs and cell lines, we demonstrate that cadherin-26 (CDH26) is abundantly expressed in differentiated AECs, localizes to the cell apices near ciliary membranes, and has functional cadherin domains with homotypic binding. We find a unique and non-redundant role for CDH26, previously uncharacterized in AECs, in regulation of cell-cell contact and cell integrity through maintaining cytoskeletal structures. Overexpression of CDH26 in cells with a fibroblastoid phenotype increases contact inhibition and promotes monolayer formation and cortical actin structures. CDH26 expression is also important for localization of planar cell polarity proteins. Knockdown of CDH26 in AECs results in loss of cortical actin and disruption of CRB3 and other proteins associated with apical polarity. Together, our findings uncover previously unrecognized functions for CDH26 in the maintenance of actin cytoskeleton and apicobasal polarity of AECs. PMID- 29449964 TI - Consequences of inadvertent intravitreal Mitomycin C injection. AB - Background: Mitomycin C (MMC) as an alkylating agent is miscellaneous an antineoplastic, antibiotic and ophthalmic agent. Here we aim to report a case of inadvertent intravitreal MMC injection instead of Avastin in case of diabetic macular edema. Case presentation: A 53 years old woman was planned to receive intravitreal Avastin injection, but accidentally, 0.05 ml of MMC 0.2% was injected. Best corrected visual acuity (BCVA) was 20/160 before injection. After 2 days, patient was referred to a tertiary referral eye center. BCVA was hand motion at presentation. Intraocular pressure was 4 mmHg. In slit lamp exams, conjunctival injection, corneal edema, Descemet fold, anterior chamber and anterior vitreous cells were presented. Pars plana vitrectomy with peripheral vitreous shaving and silicone oil tamponade was performed. Electroretinography showed undetectable responses. Ultrasound biomicroscopy showed ciliary body shortening and detachment. Optical coherent tomography showed diffuse retinal edema the day after surgery, subretinal fluid pockets in 2 weeks, and atrophy with undetectable and intertwined layers 2 months later. Gradually, like the retina, iris became atrophic and pigments were dispersed diffusely over the lens and endothelium. Conclusion: MMC is showed to be severely toxic to intraocular tissues. In our case, iris and ciliary body became atrophic. Ciliary body detachment induced hypotony. Moreover, MMC induces retinal necrosis and atrophy. Visual outcome is profoundly poor. PMID- 29449963 TI - The NSIGHT1-randomized controlled trial: rapid whole-genome sequencing for accelerated etiologic diagnosis in critically ill infants. AB - Genetic disorders are a leading cause of morbidity and mortality in infants in neonatal and pediatric intensive care units (NICU/PICU). While genomic sequencing is useful for genetic disease diagnosis, results are usually reported too late to guide inpatient management. We performed an investigator-initiated, partially blinded, pragmatic, randomized, controlled trial to test the hypothesis that rapid whole-genome sequencing (rWGS) increased the proportion of NICU/PICU infants receiving a genetic diagnosis within 28 days. The participants were families with infants aged <4 months in a regional NICU and PICU, with illnesses of unknown etiology. The intervention was trio rWGS. Enrollment from October 2014 to June 2016, and follow-up until November 2016. Of all, 26 female infants, 37 male infants, and 2 infants of undetermined sex were randomized to receive rWGS plus standard genetic tests (n = 32, cases) or standard genetic tests alone (n = 33, controls). The study was terminated early due to loss of equipoise: 73% (24) controls received genomic sequencing as standard tests, and 15% (five) controls underwent compassionate cross-over to receive rWGS. Nevertheless, intention to treat analysis showed the rate of genetic diagnosis within 28 days of enrollment (the primary end-point) to be higher in cases (31%, 10 of 32) than controls (3%, 1 of 33; difference, 28% [95% CI, 10-46%]; p = 0.003). Among infants enrolled in the first 25 days of life, the rate of neonatal diagnosis was higher in cases (32%, 7 of 22) than controls (0%, 0 of 23; difference, 32% [95% CI, 11-53%];p = 0.004). Median age at diagnosis (25 days [range 14-90] in cases vs. 130 days [range 37-451] in controls) and median time to diagnosis (13 days [range 1-84] in cases, vs. 107 days [range 21-429] in controls) were significantly less in cases than controls (p = 0.04). In conclusion, rWGS increased the proportion of NICU/PICU infants who received timely diagnoses of genetic diseases. PMID- 29449965 TI - Genetic diversity and cross-species transmission of kobuviruses in Vietnam. AB - Cross-species transmission of viruses poses a sustained threat to public health. Due to increased contact between humans and other animal species the possibility exists for cross-species transmissions and ensuing disease outbreaks. By using conventional PCR amplification and next generation sequencing, we obtained 130 partial or full genome kobuvirus sequences from humans in a sentinel cohort in Vietnam and various mammalian hosts including bats, rodents, pigs, cats, and civets. The evolution of kobuviruses in different hosts was analysed using Bayesian phylogenetic methods. We estimated and compared time of origin of kobuviruses in different host orders; we also examined the cross-species transmission of kobuviruses within the same host order and between different host orders. Our data provide new knowledge of rodent and bat kobuviruses, which are most closely related to human kobuviruses. The novel bat kobuviruses isolated from bat roosts in Southern Vietnam were genetically distinct from previously described bat kobuviruses, but closely related to kobuviruses found in rodents. We additionally found evidence of frequent cross-species transmissions of kobuviruses within rodents. Overall, our phylogenetic analyses reveal multiple cross-species transmissions both within and among mammalian species, which increases our understanding of kobuviruses genetic diversity and the complexity of their evolutionary history. PMID- 29449966 TI - Raman spectroscopic imaging for quantification of depth-dependent and local heterogeneities in native and engineered cartilage. AB - Articular cartilage possesses a remarkable, mechanically-robust extracellular matrix (ECM) that is organized and distributed throughout the tissue to resist physiologic strains and provide low friction during articulation. The ability to characterize the make-up and distribution of the cartilage ECM is critical to both understand the process by which articular cartilage undergoes disease related degeneration and to develop novel tissue repair strategies to restore tissue functionality. However, the ability to quantitatively measure the spatial distribution of cartilage ECM constituents throughout the tissue has remained a major challenge. In this experimental investigation, we assessed the analytical ability of Raman micro-spectroscopic imaging to semi-quantitatively measure the distribution of the major ECM constituents in cartilage tissues. Raman spectroscopic images were acquired of two distinct cartilage tissue types that possess large spatial ECM gradients throughout their depth: native articular cartilage explants and large engineered cartilage tissue constructs. Spectral acquisitions were processed via multivariate curve resolution to decompose the "fingerprint" range spectra (800-1800 cm-1) to the component spectra of GAG, collagen, and water, giving rise to the depth dependent concentration profile of each constituent throughout the tissues. These Raman spectroscopic acquired profiles exhibited strong agreement with profiles independently acquired via direct biochemical assaying of spatial tissue sections. Further, we harness this spectroscopic technique to evaluate local heterogeneities through the depth of cartilage. This work represents a powerful analytical validation of the accuracy of Raman spectroscopic imaging measurements of the spatial distribution of biochemical components in a biological tissue and shows that it can be used as a valuable tool for quantitatively measuring the distribution and organization of ECM constituents in native and engineered cartilage tissue specimens. PMID- 29449967 TI - Retraining walking adaptability following incomplete spinal cord injury. AB - Introduction: Functional walking requires the ability to modify one's gait pattern to environmental demands and task goals-gait adaptability. Following incomplete spinal cord injury (ISCI), gait rehabilitation such as locomotor training (Basic-LT) emphasizes intense, repetitive stepping practice. Rehabilitation approaches focusing on practice of gait adaptability tasks have not been established for individuals with ISCIs but may promote recovery of higher level walking skills. The primary purpose of this case series was to describe and determine the feasibility of administering a gait adaptability retraining approach-Adapt-LT-by comparing the dose and intensity of Adapt-LT to Basic-LT. Case presentation: Three individuals with ISCIs (>1 year, AIS C or D) completed three weeks each (15 sessions) of Basic-LT and Adapt-LT. Interventions included practice on a treadmill with body weight support and practice overground (>=30 mins total). Adapt-LT focused on speed changes, obstacle negotiation, and backward walking. Training parameters (step counts, speeds, perceived exertion) were compared and outcomes assessed pre and post interventions. Based on completion of the protocol and similarities in training parameters in the two interventions, it was feasible to administer Adapt-LT with a similar dosage and intensity as Basic-LT. Additionally, the participants demonstrated gains in walking function and balance following each training type. Discussion: Rehabilitation that includes stepping practice with adaptability tasks is feasible for individuals with ISCIs. Further investigation is needed to determine the efficacy of Adapt-LT. PMID- 29449968 TI - Use of ambulatory blood pressure monitoring in adolescents with SCI: a case series. AB - Introduction: Due the impact of maturation on cardiovascular hemodynamics the degree of cardiovascular dysfunction, attributable to spinal cord injury (SCI), in the pediatric and adolescent population remains unclear. While few studies have begun to assess this, there is still a void in the literature regarding the prevalence of cardiovascular dysfunction and how best to identify and treat it in this population. Case presentation: The purpose of this case series is to present the cardiovascular profile of three adolescent patients with chronic SCI, ages 14 16, following 2 or 3 days of 24-h Ambulatory Blood Pressure Monitoring (ABPM). Discussion: We found that there are variations across the different cases in most cardiovascular hemodynamic categories and a clarification of the International Standards to document remaining Autonomic Function after Spinal Cord Injury (ISAFSCI) may be needed to accurately identify the remaining autonomic cardiovascular function in the adolescent SCI population. PMID- 29449969 TI - Stigma and self-management: an Interpretative Phenomenological Analysis of the impact of chronic recurrent urinary tract infections after spinal cord injury. AB - Study Design: Qualitative, phenomenological design. Objectives: Neurogenic bladder dysfunction and urinary tract infection (UTI) are common secondary consequences to neurological damage to the spinal cord. This study sought to establish the impact of chronic, recurrent UTIs on people with spinal cord injury (SCI). Setting: Community sample, United Kingdom. Methods: Twelve participants with SCI, aged between 28 and 68 years, who had experienced at least three recurrent UTI events within the previous 12 months were recruited. Detailed qualitative information was obtained from semi-structured interviews, which lasted between 30 and 60 min. Interpretative Phenomenological Analysis was performed to explore the lived experience of UTIs. Results: Interview findings identified a range of factors related to the experience of recurrent UTIs in people with SCI. These were classified into the following themes: (1) Symptom Management Precedence, (2) Stigma-Motivated Risk Management and (3) Exhaustive Exploration of Treatment Options. Participants discussed management of acute exacerbations. Distress arose from perceptions of UTIs as potentially stigmatizing and fear of relying on antibiotics. Arising from this fear, many participants sought alternative prevention and management strategies. Conclusions: These results suggest that chronic recurrent UTIs act as major barriers to social participation, with adverse effects on quality of life of people with a neurogenic bladder after SCI. People with SCI would benefit from additional assessment of the impact of recurrent UTIs, so that healthcare professionals can address specific concerns, such as the psychosocial impact of urinary incontinence and stigmatizing views. Additional support to enhance self management and facilitate social participation should be provided. PMID- 29449970 TI - A systematic review: Children & Adolescents as simulated patients in health professional education. AB - Simulated patients (SP) contribute to health professional education for communication, clinical skills teaching, and assessment. Although a significant body of literature exists on the involvement of adult SPs, limited research has been conducted on the contribution of children and adolescents. This systematic review, using narrative summary with thematic synthesis, aims to report findings related to children/adolescents as simulated patients in health professions education (undergraduate or post-graduate). A systematic review of qualitative and quantitative literature published between 1980 and September 2014 was undertaken using databases including CINAHL, Ovid Medline and Scopus. The lack of literature related to the employment of children and adolescents in nursing education dictated the expansion of the search to the wider health professions. Key search terms related to the employment of children and adolescents in health professional education programs. A total of 58 studies reduced to 36 following exclusion based on abstract review. Twenty-two studies reached full text review; following application of inclusion and exclusion criteria, 15 English language studies involving children and/or adolescents in simulation formed part of this systematic review. Five key themes emerged: Process related to recruitment, duration and content of training programs, support and debriefing practice, ethical considerations, and effects of participation for key stakeholders such as children and adolescents, parent and faculty, and learner outcomes. The results suggest that the involvement of children and adolescents in simulation for education and assessment purposes is valuable and feasible. The review identified the potential for harm to children/adolescents; however, rigorous selection, training and support strategies can mitigate negative outcomes. The ability of children to portray a role consistently across assessments, and deliver constructive feedback remains ambiguous.

PMID- 29449972 TI - Complexity in simulation-based education: exploring the role of hindsight bias. AB - Simulation-based education (SBE) has the potential to misrepresent clinical practice as relatively simplistic, and as being made safer through simplistic behavioural explanations. This review provides an overview of a well-documented and robust psychological construct - hindsight bias in the context of learning in healthcare simulations. Motivating this review are our observations that post simulation debriefings may be oversimplified and biased by knowledge of scenario outcomes. Sometimes only limited consideration is given to issues that might be relevant to management in the complexity and uncertainty of real clinical practice. We use literature on hindsight bias to define the concept, inputs and implications. We offer examples from SBE where hindsight bias may occur and propose suggestions for mitigation. Influences of hindsight biases on SBE should be addressed by future studies. PMID- 29449973 TI - Observer roles that optimise learning in healthcare simulation education: a systematic review. AB - Background: Simulation is widely used in health professional education. The convention that learners are actively involved may limit access to this educational method. The aim of this paper is to review the evidence for learning methods that employ directed observation as an alternative to hands-on participation in scenario-based simulation training. We sought studies that included either direct comparison of the learning outcomes of observers with those of active participants or identified factors important for the engagement of observers in simulation. We systematically searched health and education databases and reviewed journals and bibliographies for studies investigating or referring to observer roles in simulation using mannequins, simulated patients or role play simulations. A quality framework was used to rate the studies. Methods: We sought studies that included either direct comparison of the learning outcomes of observers with those of active participants or identified factors important for the engagement of observers in simulation. We systematically searched health and education databases and reviewed journals and bibliographies for studies investigating or referring to observer roles in simulation using mannequins, simulated patients or role play simulations. A quality framework was used to rate the studies. Results: Nine studies met the inclusion criteria. Five studies suggest learning outcomes in observer roles are as good or better than hands-on roles in simulation. Four studies document learner satisfaction in observer roles. Five studies used a tool to guide observers. Eight studies involved observers in the debrief. Learning and satisfaction in observer roles is closely associated with observer tools, learner engagement, role clarity and contribution to the debrief. Learners that valued observer roles described them as affording an overarching view, examination of details from a distance, and meaningful feedback during the debrief. Learners who did not value observer roles described them as passive, or boring when compared to hands-on engagement in the simulation encounter. Conclusions: Learning outcomes and role satisfaction for observers is improved through learner engagement and the use of observer tools. The value that students attach to observer roles appear contingent on role clarity, use of observer tools, and inclusion of observers' perspectives in the debrief. PMID- 29449974 TI - A hybrid simulator model for the control of catastrophic external junctional haemorrhage in the military environment. AB - Catastrophic haemorrhage from extremity injuries has for a long time been the single most common cause of preventable death in the military environment. The effective use of extremity tourniquets has increased the survival of combat casualties, and exsanguination from isolated limb injuries is no longer the most common cause of death. Today, the most common cause of potentially preventable death is haemorrhage from the junctional zones, i.e. the most proximal part of the extremities, not amenable to standard tourniquets. Different training techniques to control catastrophic haemorrhage have been used by the Swedish Armed Forces in the pre-deployment training of physicians, nurses and medics for many years. The training techniques include different types of human patient simulators such as moulage patients and manikins. Preferred training conditions for the control of catastrophic haemorrhage include a high degree of realism, in combination with multiple training attempts. This report presents a new hybrid training model for catastrophic external junctional haemorrhage control. It offers a readily reproducible, simple and inexpensive opportunity to train personnel to deal with life threatening catastrophic junctional haemorrhage. In particular, this model offers an opportunity for non-medical military personnel in Sweden to practice control of realistic catastrophic haemorrhage, with multiple training attempts. PMID- 29449976 TI - Lessons for simulation-based education from social psychology. AB - Effective practice is informed by underlying theoretical models. Better awareness and understanding of such models can enhance reflection by practitioners on their current educational activities and so help drive the cycle of continuing improvement. In this article the author reflects on three ways in which a better understanding of social psychology gave insights into why some practices appeared to be more effective than others and some ways in which future practice could be altered. Social psychology places great emphasis on the importance of the situation in which people find themselves an how this impacts on their subsequent behaviour. The three areas specifically addressed in the article include factors which motivate and drive human activities, especially the importance of self esteem. Secondly, the relevance of the fundamental attribution error, which looks at our tendency as humans to ascribe personal attributes as the cause of the behaviour of others rather than the influence of external events. The third area to be explored is the role of acquiring scripts or heuristics that can broaden the range of activities than can be performed at a subconscious or intuitive level. For each concept, the author has included a brief illustration of its application to the practice of a simulation educator. PMID- 29449975 TI - Are simulated patients effective in facilitating development of clinical competence for healthcare students? A scoping review. AB - Background: The need to evaluate the effectiveness of SPs in improving clinical competence has attracted a heightened interest across the healthcare professions, with some prevailing gaps in their evidence. Using a scoping review approach, this study aims to provide an overview on the effectiveness of SPs in facilitating the development of clinical competence for healthcare students. Methods: This scoping review applied the first five out of the six-stage methodological framework developed by Levac et al. (Implementation Science 5:69), as follows: 1) Identify the research question; 2) identify relevant studies; 3) study selection; 4) charting the data; and 5) collating, summarising and reporting the results. The search was performed on four databases, including Medline, EMBASE, CINAHL and Scopus. Results: A total of 33 articles were included in this study (out of 968 identified), comprising of 20 cross-sectional studies, eight randomised controlled trials and five longitudinal studies. The studies were examined and categorised for further discussion in the three domains of clinical competence; technical, non-technical and cognitive skills. Overall, 24 out of 33 studies showed effectiveness of SPs in facilitating students' clinical competence. Conclusion: This scoping review serves to provide guidance for future healthcare education development, by illustrating the effectiveness of SPs in improving students' clinical competence as evidenced in the literature. In doing so, it highlights the potential of SPs in facilitating students' acquisition of the necessary skills for clinical practice. PMID- 29449977 TI - The impact of contextualization on immersion in healthcare simulation. AB - Background: The aim of this paper is to explore how contextualization of a healthcare simulation scenarios impacts immersion, by using a novel objective instrument, the Immersion Score Rating Instrument. This instrument consists of 10 triggers that indicate reduced or enhanced immersion among participants in a simulation scenario. Triggers refer to events such as jumps in time or space (sign of reduced immersion) and natural interaction with the manikin (sign of enhanced immersion) and can be used to calculate an immersion score. Methods: An experiment using a randomized controlled crossover design was conducted to compare immersion between two simulation training conditions for prehospital care: one basic and one contextualized. The Immersion Score Rating Instrument was used to compare the total immersion score for the whole scenario, the immersion score for individual mission phases, and to analyze differences in trigger occurrences. A paired t test was used to test for significance. Results: The comparison shows that the overall immersion score for the simulation was higher in the contextualized condition. The average immersion score was 2.17 (sd = 1.67) in the contextualized condition and -0.77 (sd = 2.01) in the basic condition (p < .001). The immersion score was significantly higher in the contextualized condition in five out of six mission phases. Events that might be disruptive for the simulation participants' immersion, such as interventions of the instructor and illogical jumps in time or space, are present to a higher degree in the basic scenario condition; while events that signal enhanced immersion, such as natural interaction with the manikin, are more frequently observed in the contextualized condition. Conclusions: The results suggest that contextualization of simulation training with respect to increased equipment and environmental fidelity as well as functional task alignment might affect immersion positively and thus contribute to an improved training experience. PMID- 29449978 TI - Using video-reflexive ethnography and simulation-based education to explore patient management and error recognition by pre-registration physiotherapists. AB - Background: Upon graduation, physiotherapists are required to manage clinical caseloads involving deteriorating patients with complex conditions. In particular, emergency on-call physiotherapists are required to provide respiratory/cardio-respiratory/cardiothoracic physiotherapy, out of normal working hours, without senior physiotherapist support. To optimise patient safety, physiotherapists are required to function within complex clinical environments, drawing on their knowledge and skills (technical and non technical), maintaining situational awareness and filtering unwanted stimuli from the environment. Prior to this study, the extent to which final-year physiotherapy students were able to manage an acutely deteriorating patient in a simulation context and recognise errors in their own practice was unknown. Methods: A focused video-reflexive ethnography study was undertaken to explore behaviours, error recognition abilities and personal experiences of 21 final-year (pre-registration) physiotherapy students from one higher education institution. Social constructivism and complexity theoretical perspectives informed the methodological design of the study. Video and thematic analysis of 12 simulation scenarios and video-reflexive interviews were undertaken. Results: Participants worked within the professional standards of physiotherapy practice expected of entry-level physiotherapists. Students reflected appropriate responses to their own and others' actions in the midst of uncertainty of the situation and physiological disturbances that unfolded during the scenario. However, they demonstrated a limited independent ability to recognise errors. Latent errors, active failures, error-producing factors and a series of effective defences to mitigate errors were identified through video analysis. Perceived influential factors affecting student performance within the scenario were attributed to aspects of academic and placement learning and the completion of a voluntary acute illness management course. The perceived value of the simulation scenario was enhanced by the opportunity to review their own simulation video with realism afforded by the scenario design. Conclusions: This study presents a unique insight into the experiences, skills, attitudes, behaviours and error recognition abilities of pre-registration physiotherapy students managing an acutely deteriorating patient in a simulation context. Findings of this research provide valuable insights to inform future research regarding physiotherapy practice, integration of educational methods to augment patient safety awareness and participant-led innovations in safe healthcare practice. PMID- 29449979 TI - OSCE best practice guidelines-applicability for nursing simulations. AB - Background: Objective structured clinical examinations (OSCEs) have been used for many years within healthcare programmes as a measure of students' and clinicians' clinical performance. OSCEs are a form of simulation and are often summative but may be formative. This educational approach requires robust design based on sound pedagogy to assure practice and assessment of holistic nursing care. As part of a project testing seven OSCE best practice guidelines (BPGs) across three sites, the BPGs were applied to an existing simulation activity. The aim of this study was to determine the applicability and value of the OSCE BPGs in an existing formative simulation. Methods: A mixed methods approach was used to address the research question: in what ways do OSCE BPGs align with simulations. The BPGs were aligned and compared with all aspects of an existing simulation activity offered to first-year nursing students at a large city-based university, prior to their first clinical placement in an Australian healthcare setting. Survey questions, comprised of Likert scales and free-text responses, used at other sites were slightly modified for reference to simulation. Students' opinions about the refined simulation activity were collected via electronic survey immediately following the simulation and from focus groups. Template analysis, using the BPGs as existing or a priori thematic codes, enabled interpretation and illumination of the data from both sources. Results: Few changes were made to the existing simulation plan and format. Students' responses from surveys (n = 367) and four focus groups indicated that all seven BPGs were applicable for simulations in guiding their learning, particularly in the affective domain, and assisting their perceived needs in preparing for upcoming clinical practice. Discussion: Similarities were found in the intent of simulation and OSCEs informed by the BPGs to enable feedback to students about holistic practice across affective, cognitive and psychomotor domains. The similarities in this study are consistent with findings from exploring the applicability of the BPGs for OSCEs in other nursing education settings, contexts, universities and jurisdictions. The BPGs also aligned with other frameworks and standards often used to develop and deliver simulations. Conclusions: Findings from this study provide further evidence of the applicability of the seven OSCE BPGs to inform the development and delivery of, in this context, simulation activities for nurses. The manner in which simulation is offered to large cohorts requires further consideration to meet students' needs in rehearsing the registered nurse role. PMID- 29449980 TI - Clinical exercise physiology students learning with older adults: an innovative simulation-based education programme. AB - In this paper, we report on a series of placements for clinical exercise physiology students in a simulation-based education environment with older, independent adults. The purpose of these placement opportunities was to help prepare students to work confidently and competently with older adults in primary healthcare settings. The effectiveness of these placements was measured through semi-structured interviews with the students, their supervisors and the volunteer patients, and also by analysing the content of the students' written reflection assignments. A combination of directed content analysis, informed by the research objectives and imposed upon the data, and conventional content analysis, in which codes were developed from themes emerging from the data, was adopted. Coding was based on units of meaning. Overall, the placement aims were met. Students reported increased confidence in communicating with older adults and in using the tools of their trade. This innovative simulation-based education experience helped students gain an understanding of their developing professional identities. However, the data show that some students still failed to recognise the value and importance of communication when working with older adults. The older adults reported that they enjoyed interacting with the students and believed that they had helped the students gain a positive impression of the cognitive and physical abilities of older adults. These older adults had also gained insight into the benefits of exercise physiology in terms of their own wellbeing. This paper demonstrates the benefits of engaging community support in developing healthcare workers and provides guidelines for replication of these innovative simulation-based education experiences. The paper is limited to reporting the social and community engagement benefits for older adults and the learning opportunities for the clinical exercise physiology students. Further research is needed to demonstrate the health gains for older adults who participate in such programmes. PMID- 29449981 TI - "Thinking on your feet"-a qualitative study of debriefing practice. AB - Background: Debriefing is a significant component of simulation-based education (SBE). Regardless of how and where immersive simulation is used to support learning, debriefing has a critical role to optimise learning outcomes. Although the literature describes different debriefing methods and approaches that constitute effective debriefing, there are discrepancies as to what is actually practised and how experts or experienced debriefers perceive and approach debriefing. This study sought to explore the self-reported practices of expert debriefers. Methods: We used a qualitative approach to explore experts' debriefing practices. Peer-nominated expert debriefers who use immersive manikin based simulations were identified in the healthcare simulation community across Australia. Twenty-four expert debriefers were purposively sampled to participate in semi-structured telephone interviews lasting 45-90 min. Interviews were transcribed and independently analysed using inductive thematic analysis. Results: Codes emerging through the data analysis clustered into four major categories: (1) Values: ideas and beliefs representing the fundamental principles that underpinned interviewees' debriefing practices. (2) Artistry: debriefing practices which are dynamic and creative. (3) Techniques: the specific methods used by interviewees to promote a productive and safe learning environment. (4) Development: changes in interviewees' debriefing practices over time. Conclusions: The "practice development triangle" inspired by the work of Handal and Lauvas offers a framework for our themes. A feature of the triangle is that the values of expert debriefers provide a foundation for associated artistry and techniques. This framework may provide a different emphasis for courses and programmes designed to support debriefing practices where microskill development is often privileged, especially those microskills associated with techniques (plan of action, creating a safe environment, managing learning objectives, promoting learner reflection and co-debriefing). Across the levels in the practice development triangle, the importance of continuing professional development is acknowledged. Strengths and limitations of the study are noted. PMID- 29449982 TI - Issues of cost-benefit and cost-effectiveness for simulation in health professions education. AB - Background: Simulation education can be costly-however, costs need to be considered against what you get in return to determine whether these costs are justified. Unfortunately in simulation education, evaluations that yield information about the return on investment are scarce. An economic evaluation provides a comparison of value. In short-what is it that is being obtained, what do you need to give up to get it, and how does that compare to what you get with the next best alternative? When educators are equipped with this knowledge, they will be better informed to know the place that simulation-based learning approaches should take in optimal course structures. Main body: This article provides an overview of the costs and consequences associated with simulation in healthcare education. It provides an outline of the benefits of using economic evaluations to inform decision-making by educators and clinicians concerning the most appropriate educational approaches. It also provides guidance for educational researchers interested in investigating the cost and value of their innovations. Conclusion: Measures of cost and value in simulation are required to provide information about the viability and sustainability of simulation education, enabling simulation education in health care to demonstrate its worth. PMID- 29449983 TI - Supporting transitions in medical career pathways: the role of simulation-based education. AB - Transitions, or periods of change, in medical career pathways can be challenging episodes, requiring the transitioning clinician to take on new roles and responsibilities, adapt to new cultural dynamics, change behaviour patterns, and successfully manage uncertainty. These intensive learning periods present risks to patient safety. Simulation-based education (SBE) is a pedagogic approach that allows clinicians to practise their technical and non-technical skills in a safe environment to increase preparedness for practice. In this commentary, we present the potential uses, strengths, and limitations of SBE for supporting transitions across medical career pathways, discussing educational utility, outcome and process evaluation, and cost and value, and introduce a new perspective on considering the gains from SBE. We provide case-study examples of the application of SBE to illustrate these points and stimulate discussion. PMID- 29449984 TI - Intensive simulation versus control in the assessment of time to skill competency and confidence of medical students to assess and manage cardiovascular and respiratory conditions-a pseudo-randomised trial. AB - Background: The Clinical Placement Enhancement Program (CPEP) is a simulation course for medical students learning the core topics of cardiovascular and respiratory medicine, incorporating patient safety and professionalism teaching and based on adult learning principles and proven educational theory. The aims of this study are to assess whether the CPEP delivered at the beginning of a clinical rotation would result in competency outcomes that are at least equivalent to those achieved through a standard 6-week programme and whether this programme would increase student confidence levels in assessing and managing patients with cardiovascular and respiratory conditions. Methods: This was a pseudo-randomised control trial between two groups of medical students from one clinical school. The intervention group participated in CPEP, a 4-day immersive simulation course, in the first week of their cardiac and respiratory medicine clinical rotation. The control group participants attended the normal programme of the 6-week cardiovascular and respiratory medicine clinical rotation. The programme and student competence was assessed using Observed Structured Clinical Examinations (OSCEs) and self-reported confidence surveys. Results: There was no significant difference in OSCE scoring between the intervention group (examined in week one of their clinical rotation following CPEP) and the control group (examined at the end of their full clinical rotation). Students exposed to CPEP started their clinical rotation with confidence levels similar to those reported by the control group at the end of their rotation. Confidence levels of CPEP students were higher at the end of the rotation compared to those of the control group. Conclusions: Based on OSCE results, immersion into a 4-day simulation based teaching programme at the start of a clinical rotation resulted in skill competency levels that were equivalent to those obtained after a full clinical rotation of 6 weeks. CPEP improved students' confidence levels in the assessment and management of patients presenting with cardiovascular and respiratory conditions. Simulation utilised in courses such as CPEP has the potential to enhance the overall learning experience in medical school clinical rotations. PMID- 29449985 TI - Learning curve patterns generated by a training method for laparoscopic small bowel anastomosis. AB - Background: The identification of developmental curve patterns generated by a simulation-based educational method and the variables that can accelerate the learning process will result in cost-effective training. This study describes the learning curves of a simulation-based instructional design (ID) that uses ex vivo animal models to teach laparoscopic latero-lateral small bowel anastomosis. Methods: Twenty general surgery residents were evaluated on their performance of laparoscopic latero-lateral jejuno-jejunal anastomoses (JJA) and gastro-jejunal anastomoses (GJA), using swine small bowel and stomach on an endotrainer. The ID included the following steps: (1) provision of references and videos demonstrating the surgical technique, (2) creation of an engaging context for learning, (3) critical review of the literature and video on the procedures, (4) demonstration of the critical steps, (5) hands-on practice, (6) in-action instructor's feedback, (7) quality assessment, (8) debriefing at the end of the session, and (9) deliberate and repetitive practice. Time was recorded from the beginning to the completion of the procedure, along with the presence or absence of anastomotic leaks. Results: The participants needed to perform 23.8 +/- 6.96 GJA (12-35) and 24.2 +/- 6.96 JJA (9-43) to attain proficiency. The starting point of the learning curve was higher for the GJA than for the JJA, although the slope and plateau were parallel. Further, four types of learning curves were identified: (1) exponential, (2) rapid, (3) slow, and (4) no tendency. The type of pattern could be predicted after procedure number 8. Conclusions: These findings may help to identify the learning curve of a trainee early in the developmental process, estimate the number of sessions required to reach a performance goal, determine a trainee's readiness to practice the procedure on patients, and identify the subjects who lack the innate technical abilities. It may help motivated individuals to become reflective and self-regulated learners. Moreover, the standardization of the ID may help to measure the effectiveness of learning strategies and make comparisons with other educational strategies. PMID- 29449986 TI - Measuring participants' immersion in healthcare simulation: the development of an instrument. AB - Background: Immersion is important for simulation-based education; however, questionnaire-based instruments to measure immersion have some limitations. The aim of the present work is to develop a new instrument to measure immersion among participants in healthcare simulation scenarios. Methods: The instrument was developed in four phases: trigger identification, content validity scores, inter rater reliability analysis and comparison with an existing immersion measure instrument. A modified Delphi process was used to develop the instrument and to establish validity and reliability. The expert panel consisted of 10 researchers. All the researchers in the team had previous experience of simulation in the health and/or fire and rescue services as researchers and/or educators and simulation designers. To identify triggers, the panel members independently screened video recordings from simulation scenarios. Here, a trigger is an event in a simulation that is considered a sign of reduced or enhanced immersion among simulation participants. Results: The result consists of the Immersion Score Rating Instrument (ISRI). It contains 10 triggers, of which seven indicate reduced and three enhanced immersion. When using ISRI, a rater identifies trigger occurrences and assigns them strength between 1 and 3. The content validity analysis shows that all the 10 triggers meet an acceptable content validity index for items (I-CVI) standard. The inter-rater reliability (IRR) among raters was assessed using a two-way mixed, consistency, average-measures intra-class correlation (ICC). The ICC for the difference between weighted positive and negative triggers was 0.92, which indicates that the raters are in agreement. Comparison with results from an immersion questionnaire mirrors the ISRI results. Conclusions: In conclusion, we present a novel and non-intrusive instrument for identifying and rating the level of immersion among participants in healthcare simulation scenarios. PMID- 29449987 TI - The reliability and usability of the Anesthesiologists' Non-Technical Skills (ANTS) system in simulation research. AB - Background: Non-technical skills (NTS) such as leadership and team work are important in providing good quality of care. One system to assess physicians' NTS is the Anesthesiologists' Non-Technical Skills (ANTS) system. The present study evaluates the ANTS system on the interrater reliability and usability for research purposes. Methods: Ten anesthesiologists and 20 anesthesiology residents performed two resuscitation scenarios (with and without the presence of distractors) in a simulation room with a full-scale patient simulator. The scenarios were videotaped. Two independent raters rated the NTS of the anesthesiologists using the ANTS system. The intraclass correlation coefficients (ICC) were calculated to determine the interrater reliability of both the total NTS score and the measured differences between the two scenarios. The raters filled out a questionnaire to obtain insights in the usability of the ANTS system for research purposes. Results: The ICC for the total score of the NTS was substantial (0.683), and the ICC of the elements varied between 0.371 for assessing capabilities and 0.670 for providing and maintaining standards. The intraclass correlation coefficient of measuring differences was fair (0.502). The raters judged the usability as good. Conclusions: The ANTS system was reliable for the total score and usable to measure physicians' NTS in a research setting. However, there was variation between the reliability of the elements. We recommend that if the ANTS is used for research, a pilot study should determine elements not applicable or observable in the scenario of interest; these elements should be excluded from the study. PMID- 29449988 TI - Engaging patients and clinicians through simulation: rebalancing the dynamics of care. AB - This paper proposes simulation-based enactment of care as an innovative and fruitful means of engaging patients and clinicians to create collaborative solutions to healthcare issues. This use of simulation is a radical departure from traditional transmission models of education and training. Instead, we frame simulation as co-development, through which professionals, patients and publics share their equally (though differently) expert perspectives. The paper argues that a process of participatory design can bring about new insights and that simulation offers understandings that cannot easily be expressed in words. Drawing on more than a decade of our group's research on simulation and engagement, the paper summarises findings from studies relating to clinician patient collaboration and proposes a novel approach to address the current need. The paper outlines a mechanism whereby pathways of care are jointly created, shaped, tested and refined by professionals, patients, carers and others who are affected and concerned by clinical care. PMID- 29449989 TI - The effect of implementing cognitive load theory-based design principles in virtual reality simulation training of surgical skills: a randomized controlled trial. AB - Background: Cognitive overload can inhibit learning, and cognitive load theory based instructional design principles can be used to optimize learning situations. This study aims to investigate the effect of implementing cognitive load theory-based design principles in virtual reality simulation training of mastoidectomy. Methods: Eighteen novice medical students received 1 h of self directed virtual reality simulation training of the mastoidectomy procedure randomized for standard instructions (control) or cognitive load theory-based instructions with a worked example followed by a problem completion exercise (intervention). Participants then completed two post-training virtual procedures for assessment and comparison. Cognitive load during the post-training procedures was estimated by reaction time testing on an integrated secondary task. Final product analysis by two blinded expert raters was used to assess the virtual mastoidectomy performances. Results: Participants in the intervention group had a significantly increased cognitive load during the post-training procedures compared with the control group (52 vs. 41 %, p = 0.02). This was also reflected in the final-product performance: the intervention group had a significantly lower final-product score than the control group (13.0 vs. 15.4, p < 0.005). Conclusions: Initial instruction using worked examples followed by a problem completion exercise did not reduce the cognitive load or improve the performance of the following procedures in novices. Increased cognitive load when part tasks needed to be integrated in the post-training procedures could be a possible explanation for this. Other instructional designs and methods are needed to lower the cognitive load and improve the performance in virtual reality surgical simulation training of novices. PMID- 29449990 TI - Impact of simulation-based training in surgical chest tube insertion on a model of traumatic pneumothorax. AB - Background: Chest tube insertion is required for most cases of traumatic pneumothorax. However, this procedure entails risks of potentially life threatening complications. A "surgical" approach is widely recommended to minimize these risks. Simulation-based education has previously been used in surgical chest tube insertion, but not been subjected to rigorous evaluation. Methods: The primary objective was to evaluate the success rate of surgical chest tube insertion in a task trainer (previously published). Secondary objectives were to assess performance with a performance assessment scale (previously designed), to measure the time of insertion, and to seek out a correlation between the learner's status, experience, and performance and success rate. Participants were surveyed for realism of the model and satisfaction; 65 participants (18 residents, 47 senior physicians) were randomized into SIM+ or SIM- groups. Both groups received didactic lessons. The SIM+ group was assigned deliberate practice on the model under supervision. Both groups were assessed on the model 1 month later. Results: There was no difference between the SIM+ (n = 34) and SIM- (n = 31) groups regarding status (p = 0.44) or previous surgical insertion (p = 0.12). Success rate was 97 % (SIM+) and 58 % (SIM-), p = 0.0002. Performance score was 16.29 +/- 1.82 (SIM+) and 11.39 +/- 3.67 (SIM-), p = 3.13 * 10-8. SIM+ presented shorter dissection time than SIM- (p = 0.047), but procedure time was similar (p = 0.71). Status or experience was not correlated with success rate, performance score, procedure time, or dissection time. SIM+ gained more self-confidence, judged the model more realistic, and were more satisfied than SIM-. Conclusions: Simulation-based education significantly improved the success rate and performance of surgical chest tube insertion on a traumatic pneumothorax model. PMID- 29449991 TI - From simulation research to education policy: how much evidence is enough? PMID- 29449992 TI - Non-Technical Skills Bingo-a game to facilitate the learning of complex concepts. AB - Acquiring the concepts of non-technical skills (NTS) beyond a superficial level is a challenge for healthcare professionals and simulation faculty. Current simulation-based approaches to teach NTS are challenged when learners have to master NTS concepts, clinically challenging situations, and simulation as a complex technique. The combination of all three aspects might overwhelm learners. To facilitate the deeper comprehension of NTS concepts, we describe an innovative video-based game, the Non-Technical Skills (NTS) Bingo. Participants get NTS Bingo cards that show five NTS elements each. While observing (non-medical) video clips, they try to find examples for the elements on their cards, typically observable behaviours that match a given element. After the video, participants "defend" their solution in a discussion with the game leader and other players. This discussion and the reflection aim to deepen the processing of the NTS concepts. We provide practical guidance for the conduct of NTS Bingo, including a selection of usable video clips and tips for the facilitated discussion after a clip. We use NTS in anaesthesia as example and provide guidance on how to adapt NTS Bingo to other disciplines. NTS Bingo is based on theoretical considerations on concept learning, which we describe to support the rationale for its conduct. PMID- 29449993 TI - A joint leap into a future of high-quality simulation research-standardizing the reporting of simulation science. PMID- 29449994 TI - Reporting guidelines for health care simulation research: extensions to the CONSORT and STROBE statements. AB - Background: Simulation-based research (SBR) is rapidly expanding but the quality of reporting needs improvement. For a reader to critically assess a study, the elements of the study need to be clearly reported. Our objective was to develop reporting guidelines for SBR by creating extensions to the Consolidated Standards of Reporting Trials (CONSORT) and Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) Statements. Methods: An iterative multistep consensus-building process was used on the basis of the recommended steps for developing reporting guidelines. The consensus process involved the following: (1) developing a steering committee, (2) defining the scope of the reporting guidelines, (3) identifying a consensus panel, (4) generating a list of items for discussion via online premeeting survey, (5) conducting a consensus meeting, and (6) drafting reporting guidelines with an explanation and elaboration document. Results: The following 11 extensions were recommended for CONSORT: item 1 (title/abstract), item 2 (background), item 5 (interventions), item 6 (outcomes), item 11 (blinding), item 12 (statistical methods), item 15 (baseline data), item 17 (outcomes/ estimation), item 20 (limitations), item 21 (generalizability), and item 25 (funding). The following 10 extensions were recommended for STROBE: item 1 (title/abstract), item 2 (background/rationale), item 7 (variables), item 8 (data sources/measurement), item 12 (statistical methods), item 14 (descriptive data), item 16 (main results), item 19 (limitations), item 21 (generalizability), and item 22 (funding). An elaboration document was created to provide examples and explanation for each extension. Conclusions: We have developed extensions for the CONSORT and STROBE Statements that can help improve the quality of reporting for SBR (Sim Healthcare 00:00-00, 2016). PMID- 29449995 TI - Ethical reasoning through simulation: a phenomenological analysis of student experience. AB - Background: Medical students transitioning into professional practice feel underprepared to deal with the emotional complexities of real-life ethical situations. Simulation-based learning (SBL) may provide a safe environment for students to probe the boundaries of ethical encounters. Published studies of ethics simulation have not generated sufficiently deep accounts of student experience to inform pedagogy. The aim of this study was to understand students' lived experiences as they engaged with the emotional challenges of managing clinical ethical dilemmas within a SBL environment. Methods: This qualitative study was underpinned by an interpretivist epistemology. Eight senior medical students participated in an interprofessional ward-based SBL activity incorporating a series of ethically challenging encounters. Each student wore digital video glasses to capture point-of-view (PoV) film footage. Students were interviewed immediately after the simulation and the PoV footage played back to them. Interviews were transcribed verbatim. An interpretative phenomenological approach, using an established template analysis approach, was used to iteratively analyse the data. Results: Four main themes emerged from the analysis: (1) 'Authentic on all levels?', (2)'Letting the emotions flow', (3) 'Ethical alarm bells' and (4) 'Voices of children and ghosts'. Students recognised many explicit ethical dilemmas during the SBL activity but had difficulty navigating more subtle ethical and professional boundaries. In emotionally complex situations, instances of moral compromise were observed (such as telling an untruth). Some participants felt unable to raise concerns or challenge unethical behaviour within the scenarios due to prior negative undergraduate experiences. Conclusions: This study provided deep insights into medical students' immersive and embodied experiences of ethical reasoning during an authentic SBL activity. By layering on the human dimensions of ethical decision-making, students can understand their personal responses to emotion, complexity and interprofessional working. This could assist them in framing and observing appropriate ethical and professional boundaries and help smooth the transition into clinical practice. PMID- 29449997 TI - A conceptual framework of game-informed principles for health professions education. AB - Games have been used for training purposes for many years, but their use remains somewhat underdeveloped and under-theorized in health professional education. This paper considers the basis for using serious games (games that have an explicit educational purpose) in health professional education in terms of their underlying concepts and design principles. These principles can be understood as a series of game facets: competition and conflict, chance and luck, experience and performance, simulation and make-believe, tactics and strategies, media, symbols and actions, and complexity and difficulty. Games are distinct and bound in ways that other health professional education activities are not. The differences between games and simulation can be understood in terms of the interconnected concepts of isomorphism (convergence with real-world practice) and anisomorphism (divergence from real-world practice). Gaming facets can extend the instructional design repertoire in health professional education. PMID- 29449996 TI - Simulation reframed. AB - Background: Simulation is firmly established as a mainstay of clinical education, and extensive research has demonstrated its value. Current practice uses inanimate simulators (with a range of complexity, sophistication and cost) to address the patient 'as body' and trained actors or lay people (Simulated Patients) to address the patient 'as person'. These approaches are often separate.Healthcare simulation to date has been largely for the training and assessment of clinical 'insiders', simulating current practices. A close coupling with the clinical world restricts access to the facilities and practices of simulation, often excluding patients, families and publics. Yet such perspectives are an essential component of clinical practice. Main body: This paper argues that simulation offers opportunities to move outside a clinical 'insider' frame and create connections with other individuals and groups. Simulation becomes a bridge between experts whose worlds do not usually intersect, inviting an exchange of insights around embodied practices-the 'doing' of medicine-without jeopardising the safety of actual patients.Healthcare practice and education take place within a clinical frame that often conceals parallels with other domains of expert practice. Valuable insights emerge by viewing clinical practice not only as the application of medical science but also as performance and craftsmanship.Such connections require a redefinition of simulation. Its essence is not expensive elaborate facilities. Developments such as hybrid, distributed and sequential simulation offer examples of how simulation can combine 'patient as body' with 'patient as person' at relatively low cost, democratising simulation and exerting traction beyond the clinical sphere.The essence of simulation is a purposeful design, based on an active process of selection from an originary world, abstraction of what is criterial and re-presentation in another setting for a particular purpose or audience. This may be done within traditional simulation centres, or outside in local communities, public spaces or arts and performance venues. Conclusions: Simulation has established a central role in clinical education but usually focuses on learning to do things as they are already done. Imaginatively designed, simulation offers untapped potential for deep engagement with patients, publics and experts outside medicine. PMID- 29449998 TI - How to debrief teamwork interactions: using circular questions to explore and change team interaction patterns. AB - We submit that interaction patterns within healthcare teams should be more comprehensively explored during debriefings in simulation-based training because of their importance for clinical performance. We describe how circular questions can be used for that purpose. Circular questions are based on social constructivism. They include a variety of systemic interviewing methods. The goals of circular questions are to explore the mutual dependency of team members' behavior and recurrent behavior patterns, to generate information, to foster perspective taking, to "fluidize" problems, and to put actions into relational contexts. We describe the nature of circular questions, the benefits they offer, and ways of applying them during debriefings. PMID- 29449999 TI - "Hand-it-on": an innovative simulation on the relation of non-technical skills to healthcare. AB - Non-technical skills (NTS) are an integral part of the abilities healthcare professionals need to optimally care for patients. Integrating NTS into the already complex tasks of healthcare can be a challenge for clinicians. Integrating NTS into simulation-based training increases the demands for simulation instructors with regard to scenario design, conduct, and debriefing. We introduce a simulation game, Hand-it-on, that can trigger discussions on how NTS can influence work processes. Hand-it-on aims to help clinicians and simulation instructors alike to improve their understanding of NTS concepts and where they can apply them in their work. It complements existing approaches to teaching NTS by limiting the complexity of the game and by removing medical content, allowing learners to concentrate on NTS. Hand-it-on is relevant for groups and teams working across the range of different healthcare contexts. During Hand-it-on, participants stand in a circle and hand on everyday objects to each other according to simple rules, resulting in many events that can be debriefed in relation to safe patient care. We describe both the conduct of Hand it-on and ideas on how to debrief participants. We provide variations that can be used in different contexts, focusing the exercise on different learning goals. We also offer the theoretical rationale for using an out-of-context simulation in combination with other forms of teaching. Although we did not evaluate Hand-it-on formally, oral feedback from participants and the replication of Hand-it-on by many simulation teams support its value. PMID- 29450000 TI - Validation of educational assessments: a primer for simulation and beyond. AB - Background: Simulation plays a vital role in health professions assessment. This review provides a primer on assessment validation for educators and education researchers. We focus on simulation-based assessment of health professionals, but the principles apply broadly to other assessment approaches and topics. Key principles: Validation refers to the process of collecting validity evidence to evaluate the appropriateness of the interpretations, uses, and decisions based on assessment results. Contemporary frameworks view validity as a hypothesis, and validity evidence is collected to support or refute the validity hypothesis (i.e., that the proposed interpretations and decisions are defensible). In validation, the educator or researcher defines the proposed interpretations and decisions, identifies and prioritizes the most questionable assumptions in making these interpretations and decisions (the "interpretation-use argument"), empirically tests those assumptions using existing or newly-collected evidence, and then summarizes the evidence as a coherent "validity argument." A framework proposed by Messick identifies potential evidence sources: content, response process, internal structure, relationships with other variables, and consequences. Another framework proposed by Kane identifies key inferences in generating useful interpretations: scoring, generalization, extrapolation, and implications/decision. We propose an eight-step approach to validation that applies to either framework: Define the construct and proposed interpretation, make explicit the intended decision(s), define the interpretation-use argument and prioritize needed validity evidence, identify candidate instruments and/or create/adapt a new instrument, appraise existing evidence and collect new evidence as needed, keep track of practical issues, formulate the validity argument, and make a judgment: does the evidence support the intended use? Conclusions: Rigorous validation first prioritizes and then empirically evaluates key assumptions in the interpretation and use of assessment scores. Validation science would be improved by more explicit articulation and prioritization of the interpretation-use argument, greater use of formal validation frameworks, and more evidence informing the consequences and implications of assessment. PMID- 29450001 TI - Simulation as a toolkit-understanding the perils of blood transfusion in a complex health care environment. AB - Background: Administration of blood is a complex process requiring vigilance and effective teamwork. Despite strict policies and training on blood administration, errors still occur and can lead to mistransfusion with adverse patient outcomes. We used an in situ simulated scenario within an operating room (OR) to identify weaknesses in the current process and hazards that could contribute to mistransfusion. Methods: A process checklist of critical steps of safe transfusion was developed based on a large academic centre's internal hospital policy and practice. Ten standardized operating room scenarios were conducted involving management of postoperative bleeding. Scenarios lasted 20 min or until blood transfusion was started. Debriefing followed immediately. Video recordings were reviewed, scored, and evaluated for team performance. Latent safety threats were identified. Focus groups further helped to identify rationale for decisions made. Participants completed questionnaires to evaluate the exercise. Results: Forty-three experienced OR professionals participated. Of the 19 steps identified as essential for the safe administration of blood components, the median number of steps correctly completed per team was 11. The largest number of errors occurred when different team members interacted and during the immediate pre transfusion check. We report that this type of learning immediately increased participants' self-reported ability to perform in a team (90%) and to improve clinical care (88%). Conclusions: In situ simulation is valuable in identifying common susceptibilities in blood administration error in a complex healthcare organization. Administrators and clinicians may wish to use simulation as an opportunity for system improvement in the delivery of quality care. PMID- 29450002 TI - Sharing simulation-based training courses between institutions: opportunities and challenges. AB - Background: Sharing simulation-based training (SBT) courses between institutions could reduce time to develop new content but also presents challenges. We evaluate the process of sharing SBT courses across institutions in a mixed method study estimating the time required and identifying barriers and potential solutions. Methods: Two US academic medical institutions explored instructor experiences with the process of sharing four courses (two at each site) using personal interviews and a written survey and estimated the time needed to develop new content vs implement existing SBT courses. Results: The project team spent approximately 618 h creating a collaboration infrastructure to support course sharing. Sharing two SBT courses was estimated to save 391 h compared with developing two new courses. In the qualitative analysis, participants noted the primary benefit of course sharing was time savings. Barriers included difficulty finding information and understanding overall course flow. Suggestions for improvement included establishing a standardized template, clearly identifying the target audience, providing a course overview, communicating with someone familiar with the original SBT course, employing an intuitive file-sharing platform, and considering local culture, context, and needs. Conclusions: Sharing SBT courses between institutions is feasible but not without challenges. An initial investment in a sharing infrastructure may facilitate downstream time savings compared with developing content de novo. PMID- 29450003 TI - Simulation and mental health outcomes: a scoping review. AB - Background: A scoping review was conducted in order to map and determine the gaps in literature on the impact of simulation as an educational approach to improve mental health care outcomes. As it became apparent that no literature existed on this topic, the study aimed to examine the educational impact of simulation on mental health education. Methods: An established five-stage scoping methodology was used: (1) identification of the research question, (2) identification of relevant studies, (3) study selection, (4) charting the data and (5) collation, summarising and reporting of results. CINAHL, ProQuest, PubMed, MEDLINE, EMBASE and PsychINFO databases were searched. These databases were deemed to represent a majority of the literature while accommodating for the particular search strategy used for this review. Websites that provide grey literature were also searched for articles of relevance. Results: A total of 48 articles were included in this review, with a considerable portion of studies conducted in the USA and UK. Others were conducted in an array of locations including Australia, Canada, Iran and Taiwan. Of the included articles, seven groups of simulation methods (including standardised patients, virtual reality and manikins as patients) were evident, with standardised patients being most prominent. Conclusions: Literature is lacking to evidence the benefit of simulation on mental health patient outcomes. However, the available literature suggests a variety of simulation based education, and training methods are currently being used within mental healthcare education. The findings do suggest some methods of simulation, such as the use of standardised patients, are more commonly used in education and have been deemed as effective to assist in mental health education. As no article specifically examining the mental health outcomes of patients treated by health professionals taught by simulation was identified, the educational outcomes outlined in this paper may be used to inform further research, incorporating mental health patient outcomes. PMID- 29450004 TI - Serious games for health: three steps forwards. AB - Serious games are educational tools which are more and more used in patient and health professional education. In this article, we discuss three main points that developers and educators need to address during the development of a serious game for health. We first explain how to develop motivating serious games by finding a point where the intrinsic and extrinsic motivations of end users can converge. Then, we propose to identify the features of serious games which enhance their learning effectiveness on the basis of a framework derived from cognitive science and called "the four pillars of learning." Finally, we discuss issues and solutions related to the evaluation of serious games. PMID- 29450005 TI - Designing in situ simulation in the emergency department: evaluating safety attitudes amongst physicians and nurses. AB - Background: This intervention study aimed to enhance patient safety attitudes through the design of an in situ simulation program based on a needs analysis involving thematic analysis of patient safety data and short-term ethnography. The study took place at an Emergency Department (ED) in the Central Region of Denmark. Research suggests that poor handover communication can increase the likelihood of critical incidents and adverse events in the ED. Furthermore, simulation is an effective strategy for training handover communication skills. Research is lacking, however, on how to use patient safety data and a needs analysis to the design of in situ simulation communication training. Methods: This is a prospective pre-post study investigating the interventional effects of in situ simulation. It used a three-pronged strategy: (1) thematic analysis of patient safety data consisting of reported critical incidents and adverse events, (2) a needs analysis based on short-term ethnography in the ED, and (3) pre-post evaluation using the validated Safety Attitudes Questionnaire (SAQ) and the Trainee Reactions Score. Results: Sixteen different healthcare teams participated composed by 9 physicians and 30 nurses. In the SAQ, participating staff scored their safety attitudes in six categories (n = 39). Two measures where significantly higher for the post-SAQ than those for the pre-SAQ: teamwork climate (p < 0.001) and safety climate (p < 0.05). The Trainee Reactions Score showed that the training was positively evaluated. Conclusions: This study designed a feasible strategy for implementing in situ simulation based on a needs analysis of critical incidents and adverse events and short-term ethnography. PMID- 29450006 TI - An experimental study on the impact of clinical interruptions on simulated trainee performances of central venous catheterization. AB - Background: Interruptions are common in the healthcare setting. This experimental study compares the effects of interruptions on simulated performances of central venous catheterization during a highly versus minimally complex portion of the task. Methods: Twenty-six residents were assigned to interruptions during tasks that are (1) highly complex: establishing ultrasound-guided venous access (experimental group, n = 15) or (2) minimally complex: skin cleansing (control group, n = 11). Primary outcomes were (a) performance scores at three time points measured with a validated checklist, (b) time spent on the respective tasks, and (c) number of attempts to establish venous access. Results: Repeated measure analyses of variances of performance scores over time indicated no main effect of time or group. The interaction between time and group was significant: F (2, 44) = 4.28, p = 0.02, and partial eta2 = 0.16, indicating a large effect size. The experimental group scores decreased steadily over time, while the control group scores increased with time. The experimental group required longer to access the vein (148 s; interquartile range (IQR) 60 to 361 vs. 44 s; IQR 27 to 133 s; p = 0.034). Median number of attempts to establish venous access was higher in the experimental group (2, IQR 1-7 vs. 1, IQR 1-2; p = 0.03). Conclusions: Interruptions during a highly complex task resulted in a consistent decrement in performance scores, longer time required to perform the task, and a higher number of venous access attempts than interruptions during a minimally complex tasks. We recommend avoiding interrupting trainees performing bedside procedures. PMID- 29450007 TI - Conducting multicenter research in healthcare simulation: Lessons learned from the INSPIRE network. AB - Simulation-based research has grown substantially over the past two decades; however, relatively few published simulation studies are multicenter in nature. Multicenter research confers many distinct advantages over single-center studies, including larger sample sizes for more generalizable findings, sharing resources amongst collaborative sites, and promoting networking. Well-executed multicenter studies are more likely to improve provider performance and/or have a positive impact on patient outcomes. In this manuscript, we offer a step-by-step guide to conducting multicenter, simulation-based research based upon our collective experience with the International Network for Simulation-based Pediatric Innovation, Research and Education (INSPIRE). Like multicenter clinical research, simulation-based multicenter research can be divided into four distinct phases. Each phase has specific differences when applied to simulation research: (1) Planning phase, to define the research question, systematically review the literature, identify outcome measures, and conduct pilot studies to ensure feasibility and estimate power; (2) Project Development phase, when the primary investigator identifies collaborators, develops the protocol and research operations manual, prepares grant applications, obtains ethical approval and executes subsite contracts, registers the study in a clinical trial registry, forms a manuscript oversight committee, and conducts feasibility testing and data validation at each site; (3) Study Execution phase, involving recruitment and enrollment of subjects, clear communication and decision-making, quality assurance measures and data abstraction, validation, and analysis; and (4) Dissemination phase, where the research team shares results via conference presentations, publications, traditional media, social media, and implements strategies for translating results to practice. With this manuscript, we provide a guide to conducting quantitative multicenter research with a focus on simulation-specific issues. PMID- 29450008 TI - The effects of active (hot-seat) versus observer roles during simulation-based training on stress levels and non-technical performance: a randomized trial. AB - Background: Active 'hands-on' participation in the 'hot-seat' during immersive simulation-based training (SBT) induces stress for participants, which is believed to be necessary to improve performance. We hypothesized that observers of SBT can subsequently achieve an equivalent level of non-technical performance as 'hot-seat' participants despite experiencing lower stress. Methods: We randomized 37 anaesthesia trainees into two groups to undergo three consecutive SBT scenarios. Eighteen 'hot-seat' trainees actively participated in all three scenarios, and 19 'observer' trainees were directed to observe the first two scenarios and participated in the 'hot-seat' only in scenario 3. Salivary cortisol (SC) was measured at four time points during each scenario. Primary endpoint for stress response was the change in SC (DeltaSC) from baseline. Performance was measured using the Anaesthetist's Non-Technical Skills (ANTS) Score. Results: Mean SC increased in all participants whenever they were in the 'hot-seat' role, but not when in the observer role. Hot-seat DeltaSC (mcg/dL) for scenarios 1, 2, and 3 were 0.122 (p = 0.001), 0.074 (p = 0.047), and 0.085 (p = 0.023), respectively. Observers DeltaSC (mcg/dL) for scenarios 1, 2, and 3 were 0.062 (p = 0.091), 0.010 (p = 0.780), and 0.144 (p = 0.001), respectively. Mean ANTS scores were equivalent between the 'hot-seat' (40.0) and 'observer' (39.4) groups in scenario 3 (p = 0.733). Conclusions: Observers of SBT achieved an equivalent level of non-technical performance, while experiencing lower stress than trainees repeatedly trained in the 'hot-seat'. Our findings suggest that directed observers may benefit from immersive SBT even without repeated 'hands on' experience and stress in the hot-seat. The directed observer role may offer a less stressful, practical alternative to the traditional 'hot-seat' role, potentially rendering SBT accessible to a wider audience.

PMID- 29450009 TI - Students' understanding of teamwork and professional roles after interprofessional simulation-a qualitative analysis. AB - Background: This study explores how interprofessional simulation-based education (IPSE) can contribute to a change in students' understanding of teamwork and professional roles. A series of 1-day training sessions was arranged involving undergraduate nursing and medical students. Scenarios were designed for practicing teamwork principles and interprofessional communication skills by endorsing active participation by all team members. Methods: Four focus groups occurred 2-4 weeks after the training. Thematic analysis of the transcribed focus groups was applied, guided by questions on what changes in students' understanding of teamwork and professional roles were identified and how such changes had been achieved. Results: The first question, aiming to identify changes in students' understanding of teamwork, resulted in three categories: realizing and embracing teamwork fundamentals, reconsidering professional roles, and achieving increased confidence. The second question, regarding how participation in IPSE could support the transformation of students' understanding of teamwork and of professional roles, embraced another three categories: feeling confident in the learning environment, embodying experiences, and obtaining an outside perspective. Conclusions: This study showed the potential of IPSE to transform students' understanding of others' professional roles and responsibilities. Students displayed extensive knowledge on fundamental teamwork principles and what these meant in the midst of participating in the scenarios. A critical prerequisite for the development of these new insights was to feel confident in the learning environment. The significance of how the environment was set up calls for further research on the design of IPSE in influencing role understanding and communicative skills in significant ways. PMID- 29450010 TI - An institution-wide approach to submission, review, and funding of simulation based curricula. AB - This article describes the development, implementation, and modification of an institutional process to evaluate and fund graduate medical education simulation curricula. The goals of this activity were to (a) establish a standardized mechanism for proposal submission and evaluation, (b) identify simulation-based medical education (SBME) curricula that would benefit from mentored improvement before implementation, and (c) ensure that funding decisions were fair and defensible. Our intent was to develop a process that was grounded in sound educational principles, allowed for efficient administrative oversight, ensured approved courses were high quality, encouraged simulation education research and scholarship, and provided opportunities for medical specialties that had not previously used SBME to receive mentoring and faculty development. PMID- 29450011 TI - The Association of Standardized Patient Educators (ASPE) Standards of Best Practice (SOBP). AB - In this paper, we define the Association of Standardized Patient Educators (ASPE) Standards of Best Practice (SOBP) for those working with human role players who interact with learners in a wide range of experiential learning and assessment contexts. These human role players are variously described by such terms as standardized/simulated patients or simulated participants (SP or SPs). ASPE is a global organization whose mission is to share advances in SP-based pedagogy, assessment, research, and scholarship as well as support the professional development of its members. The SOBP are intended to be used in conjunction with the International Nursing Association for Clinical Simulation and Learning (INACSL) Standards of Best Practice: SimulationSM, which address broader simulation practices. We begin by providing a rationale for the creation of the ASPE SOBP, noting that with the increasing use of simulation in healthcare training, it is incumbent on ASPE to establish SOBP that ensure the growth, integrity, and safe application of SP-based educational endeavors. We then describe the three and a half year process through which these standards were developed by a consensus of international experts in the field. Key terms used throughout the document are defined. Five underlying values inform the SOBP: safety, quality, professionalism, accountability, and collaboration. Finally, we describe five domains of best practice: safe work environment; case development; SP training for role portrayal, feedback, and completion of assessment instruments; program management; and professional development. Each domain is divided into principles with accompanying key practices that provide clear and practical guidelines for achieving desired outcomes and creating simulations that are safe for all stakeholders. Failure to follow the ASPE SOBP could compromise the safety of participants and the effectiveness of a simulation session. Care has been taken to make these guidelines precise yet flexible enough to address the diversity of varying contexts of SP practice. As a living document, these SOBP will be reviewed and modified periodically under the direction of the ASPE Standards of Practice Committee as SP methodology grows and adapts to evolving simulation practices. PMID- 29450012 TI - Cumulative evaluation data: pediatric airway management simulation courses for pediatric residents. AB - Objectives: To utilize cumulative evaluation data of the pediatric airway management simulation-based learning course on knowledge and practical skills of residents in the Saudi Commission for Health Speciality (SCFHS) in order to measure its efficacy and areas for improvement. Methods: The evaluation is a retrospective cohort study that compares pre- and post-test (knowledge and skills) of a pediatric airway management simulation course. The 2-day course has been conducted four times annually at CRESENT and is comprised of interactive lectures on airway management and crew resource management, a demonstration of fundamentals of intubation, three skill stations, and six case scenarios with debriefing. Our evaluation data includes all pediatric residents who attended the course between January and December 2015. Results: Forty-six residents participated, of whom 30 (65.2%) are male and 16 (34.78%) are female. Overall, there is statistically significant improvement between the pre-test and post-test knowledge and practical skill scores. The pre-test scores are significantly different between the four different resident levels with p values of 0.003 and <0.001 respectively. However, there are no statistically significant differences in the post-test scores among the four different resident levels with p values of 0.372 and 0.133 respectively. The practical skill assessment covers four main domains. Improvements were noted in pharmacology (811%), equipment setup (250%), intubation steps (200%), and patient positioning (130%). The post-test scores are similar in all practical skill categories for the four different residency levels. Discussion: Our outcome-based evaluation strategy demonstrated that residents met the course learning objectives. The pediatric airway management simulation course at CRESENT is effective in improving the knowledge and practical skills of pediatric residents. Although the greatest improvement is noted among junior residents, learners from different residency levels have comparable knowledge and practical skills at the end of the course. Things that can be improved based on our study results include stressing more the type and dosages of the medications used in airway management and mandating the course for all junior pediatric residents. Although residents scored well, specific knowledge and skill elements still led us to targeted areas for course excellence. Similar courses need to be integrated in the pediatric residency curriculum. Further research is needed to study skill retention and more importantly its impact on patients' care. Although resource-intensive, the use of cumulative evaluation data helped to focus quality improvement in our courses. PMID- 29450013 TI - Early acquisition of non-technical skills using a blended approach to simulation based medical education. AB - Background: Non-technical skills are emerging as an important component of postgraduate medical education. Between 2013 and 2016, a new blended training program incorporating non-technical skills was introduced at an Australian university affiliated hospital. Program participants were medical officers in years 1 and 2 of postgraduate training. Methods: An interdisciplinary faculty trained in simulation-based education led the program. The blended approach combined open access online resources with multiple opportunities to participate in simulation-based learning. The aim of the study was to examine the value of the program to the participants and the effects on the wider hospital system. The mixed methods evaluation included data from simulation centre records, hospital quality improvement data, and a post-hoc reflective survey of the enrolled participants (n = 68). Results: Over 30 months, 283 junior doctors were invited to participate in the program. Enrolment in a designated simulation-based course was completed by 169 doctors (59.7%). Supplementary revision sessions were made available to the cohort with a median weekly attendance of five participants. 56/68 (82.4%) of survey respondents reported increased confidence in managing deteriorating patients. During the period of implementation, the overall rate of hospital cardiac arrests declined by 42.3%. Future objectives requested by participants included training in graded assertiveness and neurological emergencies. Conclusions: Implementation of a non-technical skills program was achieved with limited simulation resources and was associated with observable improvements in clinical performance. The participants surveyed reported increased confidence in managing deteriorating patients, and the program introduction coincided with a significant reduction in the rate of in-hospital cardiac arrests. PMID- 29450014 TI - A simulated "Night-onCall" to assess and address the readiness-for-internship of transitioning medical students. AB - Transitioning medical students are anxious about their readiness-for-internship, as are their residency program directors and teaching hospital leadership responsible for care quality and patient safety. A readiness-for-internship assessment program could contribute to ensuring optimal quality and safety and be a key element in implementing competency-based, time-variable medical education. In this paper, we describe the development of the Night-onCall program (NOC), a 4 h readiness-for-internship multi-instructional method simulation event. NOC was designed and implemented over the course of 3 years to provide an authentic "night on call" experience for near graduating students and build measurements of students' readiness for this transition framed by the Association of American Medical College's Core Entrustable Professional Activities for Entering Residency. The NOC is a product of a program of research focused on questions related to enabling individualized pathways through medical training. The lessons learned and modifications made to create a feasible, acceptable, flexible, and educationally rich NOC are shared to inform the discussion about transition to residency curriculum and best practices regarding educational handoffs from undergraduate to graduate education. PMID- 29450015 TI - Tracing the prescription journey: a qualitative evaluation of an interprofessional simulation-based learning activity. AB - Background: In many countries across the world, the majority of prescribing occurs within the community setting. Close collaboration between general practitioners (GPs) and pharmacists is required to ensure effective therapeutic treatment of patients, whilst minimising prescribing and dispensing errors. Despite the need to work collaboratively, medical and pharmacy training is often unilateral. Interprofessional education (IPE) and simulation-based education (SBE) are teaching approaches widely used by healthcare professionals to foster collaborative practice. At Queen's University Belfast (QUB), an innovative IPE activity was developed for medical and pharmacy undergraduate students that aimed to develop a greater understanding of their roles and duties in community prescribing and dispensing. This study set out to evaluate the impact of such a SBE activity on students' attitudes towards collaborative practice in prescribing and dispensing medication in the community. Methods: Interprofessional groups of year 3 pharmacy (n = 10) and year 4 medical (n = 9) students took part in a SBE activity. This focused on the IPE team clinically assessing, diagnosing, writing prescriptions, dispensing medication(s) and counselling a simulated patient (in a simulated practice and pharmacy setting). Using a questioning guide, four focus groups of medical and pharmacy students were used to evaluate their attitudes towards the simulated IPE activity. Interviews were audio-recorded, transcribed and analysed iteratively using thematic analysis. Results: Four main themes emerged from the analysis: (1) IPE simulation activity: creating a broader learning experience; (2) patient-centred practice: a shared understanding; (3) professional skills: explored and shared; and (4) professional roles: a journey of discovery, respect and stereotypes. Conclusions: Students broadened their knowledge of each other's expertise in skills and clinical roles whilst working together. Furthermore, students valued the opportunity to strengthen cooperation with their future colleagues with the shared goal of improving patient-centred care. PMID- 29450016 TI - Simulation in the clinical setting: towards a standard lexicon. AB - Simulation-based educational activities are happening in the clinical environment but are not all uniform in terms of their objectives, delivery, or outputs. While these activities all provide an opportunity for individual and team training, nuances in the location, timing, notification, and participants impact the potential outcomes of these sessions and objectives achieved. In light of this, there are actually many different types of simulation-based activity that occur in the clinical environment, which has previously all been grouped together as "in situ" simulation. However, what truly defines in situ simulation is how the clinical environment responds in its' natural state, including the personnel, equipment, and systems responsible for care in that environment. Beyond individual and team skill sets, there are threats to patient safety or quality patient care that result from challenges with equipment, processes, or system breakdowns. These have been labeled "latent safety threats." We submit that the opportunity for discovery of latent safety threats is what defines in situ simulation and truly differentiates it from what would be more rightfully called "on-site" simulation. The distinction between the two is highlighted in this article, as well as some of the various sub-types of in situ simulation. PMID- 29450017 TI - Distributed Simulation as a modelling tool for the development of a simulation based training programme for cardiovascular specialties. AB - Aims and background: Distributed Simulation is the concept of portable, high fidelity immersive simulation. Here, it is used for the development of a simulation-based training programme for cardiovascular specialities. We present an evidence base for how accessible, portable and self-contained simulated environments can be effectively utilised for the modelling, development and testing of a complex training framework and assessment methodology. Iterative user feedback through mixed-methods evaluation techniques resulted in the implementation of the training programme. Approach: Four phases were involved in the development of our immersive simulation-based training programme: (1) initial conceptual stage for mapping structural criteria and parameters of the simulation training framework and scenario development (n = 16), (2) training facility design using Distributed Simulation, (3) test cases with clinicians (n = 8) and collaborative design, where evaluation and user feedback involved a mixed-methods approach featuring (a) quantitative surveys to evaluate the realism and perceived educational relevance of the simulation format and framework for training and (b) qualitative semi-structured interviews to capture detailed feedback including changes and scope for development. Refinements were made iteratively to the simulation framework based on user feedback, resulting in (4) transition towards implementation of the simulation training framework, involving consistent quantitative evaluation techniques for clinicians (n = 62). For comparative purposes, clinicians' initial quantitative mean evaluation scores for realism of the simulation training framework, realism of the training facility and relevance for training (n = 8) are presented longitudinally, alongside feedback throughout the development stages from concept to delivery, including the implementation stage (n = 62). Findings: Initially, mean evaluation scores fluctuated from low to average, rising incrementally. This corresponded with the qualitative component, which augmented the quantitative findings; trainees' user feedback was used to perform iterative refinements to the simulation design and components (collaborative design), resulting in higher mean evaluation scores leading up to the implementation phase. Conclusions: Through application of innovative Distributed Simulation techniques, collaborative design, and consistent evaluation techniques from conceptual, development, and implementation stages, fully immersive simulation techniques for cardiovascular specialities are achievable and have the potential to be implemented more broadly.

AB - This paper presents a description of, and some reflections around, the experience of implementing simulation-based education within a nursing education programme in a low-income context. The students in the nursing education programme found the simulation sessions to be useful, motivating and a realistic learning method. Our experience may provide useful insight for other nursing education programmes in low-income contexts. It looks like a deeper knowledge about the feasibility of simulation-based education from both the teacher and student perspective is necessary.

A functional view of in situ simulation. AB - Healthcare simulation has been widely adopted for health professional education at all stages of training and practice and across cognitive, procedural, communication and teamwork domains. Recent enthusiasm for in situ simulation delivered in the real clinical environment-cites improved transfer of knowledge and skills into real-world practice, as well as opportunities to identify latent safety threats and other workplace-specific issues. However, describing simulation type according to place may not be helpful. Instead, I propose the term translational simulation as a functional term for how simulation may be connected directly with health service priorities and patient outcomes, through interventional and diagnostic functions, independent of the location of the simulation activity. PMID- 29450022 TI - Variation and adaptation: learning from success in patient safety-oriented simulation training. AB - Simulation is traditionally used to reduce errors and their negative consequences. But according to modern safety theories, this focus overlooks the learning potential of the positive performance, which is much more common than errors. Therefore, a supplementary approach to simulation is needed to unfold its full potential. In our commentary, we describe the learning from success (LFS) approach to simulation and debriefing. Drawing on several theoretical frameworks, we suggest supplementing the widespread deficit-oriented, corrective approach to simulation with an approach that focusses on systematically understanding how good performance is produced in frequent (mundane) simulation scenarios. We advocate to investigate and optimize human activity based on the connected layers of any setting: the embodied competences of the healthcare professionals, the social and organizational rules that guide their actions, and the material aspects of the setting. We discuss implications of these theoretical perspectives for the design and conduct of simulation scenarios, post-simulation debriefings, and faculty development programs. PMID- 29450023 TI - Reducing the impact of intensive care unit mattress compressibility during CPR: a simulation-based study. AB - Background: The depth of chest compression (CC) during cardiac arrest is associated with patient survival and good neurological outcomes. Previous studies showed that mattress compression can alter the amount of CCs given with adequate depth. We aim to quantify the amount of mattress compressibility on two types of ICU mattresses and explore the effect of memory foam mattress use and a backboard on mattress compression depth and effect of feedback source on effective compression depth. Methods: The study utilizes a cross-sectional self-control study design. Participants working in the pediatric intensive care unit (PICU) performed 1 min of CC on a manikin in each of the following four conditions: (i) typical ICU mattress; (ii) typical ICU mattress with a CPR backboard; (iii) memory foam ICU mattress; and (iv) memory foam ICU mattress with a CPR backboard, using two different sources of real-time feedback: (a) external accelerometer sensor device measuring total compression depth and (b) internal light sensor measuring effective compression depth only. CPR quality was concurrently measured by these two devices. The differences of the two measures (mattress compression depth) were summarized and compared using multilevel linear regression models. Effective compression depths with different sources of feedback were compared with a multilevel linear regression model. Results: The mean mattress compression depth varied from 24.6 to 47.7 mm, with percentage of depletion from 31.2 to 47.5%. Both use of memory foam mattress (mean difference, MD 11.7 mm, 95%CI 4.8 18.5 mm) and use of backboard (MD 11.6 mm, 95% CI 9.0-14.3 mm) significantly minimized the mattress compressibility. Use of internal light sensor as source of feedback improved effective CC depth by 7-14 mm, compared with external accelerometer sensor. Conclusion: Use of a memory foam mattress and CPR backboard minimizes mattress compressibility, but depletion of compression depth is still substantial. A feedback device measuring sternum-to-spine displacement can significantly improve effective compression depth on a mattress. Trial registration: Not applicable. This is a mannequin-based simulation research. PMID- 29450024 TI - An activity theory perspective of how scenario-based simulations support learning: a descriptive analysis. AB - Background: The dominant frameworks for describing how simulations support learning emphasize increasing access to structured practice and the provision of feedback which are commonly associated with skills-based simulations. By contrast, studies examining student participants' experiences during scenario based simulations suggest that learning may also occur through participation. However, studies directly examining student participation during scenario-based simulations are limited. This study examined the types of activities student participants engaged in during scenario-based simulations and then analyzed their patterns of activity to consider how participation may support learning. Methods: Drawing from Engestrom's first-, second-, and third-generation activity systems analysis, an in-depth descriptive analysis was conducted. The study drew from multiple qualitative methods, namely narrative, video, and activity systems analysis, to examine student participants' activities and interaction patterns across four video-recorded simulations depicting common motivations for using scenario-based simulations (e.g., communication, critical patient management). Results: The activity systems analysis revealed that student participants' activities encompassed three clinically relevant categories, including (a) use of physical clinical tools and artifacts, (b) social interactions, and (c) performance of structured interventions. Role assignment influenced participants' activities and the complexity of their engagement. Importantly, participants made sense of the clinical situation presented in the scenario by reflexively linking these three activities together. Specifically, student participants performed structured interventions, relying upon the use of physical tools, clinical artifacts, and social interactions together with interactions between students, standardized patients, and other simulated participants to achieve their goals. When multiple student participants were present, such as in a team-based scenario, they distributed the workload to achieve their goals. Conclusion: The findings suggest that student participants learned as they engaged in these scenario-based simulations when they worked to make sense of the patient's clinical presentation. The findings may provide insight into how student participants' meaning-making efforts are mediated by the cultural artifacts (e.g., physical clinical tools) they access, the social interactions they engage in, the structured interventions they perform, and the roles they are assigned. The findings also highlight the complex and emergent properties of scenario-based simulations as well as how activities are nested. Implications for learning, instructional design, and assessment are discussed. PMID- 29450026 TI - Method matters: impact of in-scenario instruction on simulation-based teamwork training. AB - Background: The rationale for introducing full-scale patient simulators in training to improve patient safety is to recreate clinical situations in a realistic setting. Although high-fidelity simulators mimic a wide range of human features, simulators differ from the body of a sick patient. The gap between the simulator and the human body implies a need for facilitators to provide information to help participants understand scenarios. The authors aimed at describing different methods that facilitators in our dataset used to provide such extra scenario information and how the different methods to convey information affected how scenarios played out. Methods: A descriptive qualitative study was conducted to examine the variation of methods to deliver extra scenario information to participants. A multistage approach was employed. The authors selected film clips from a shared database of 31 scenarios from three participating simulation centers. A multidisciplinary research team performed a collaborative analysis of representative film clips focusing on the interplay between participants, facilitators, and the physical environment. After that, the entire material was revisited to further examine and elaborate the initial findings. Results: The material displayed four distinct methods for facilitators to convey information to participants in simulation-based teamwork training. The choice of method had impact on the participating teams regarding flow of work, pace, and team communication. Facilitators' close access to the teams' activities when present in the simulation suite, either embodied or disembodied in the simulation, facilitated the timing for providing information, which was critical for maintaining the flow of activities in the scenario. The mediation of information by a loudspeaker or an earpiece from the adjacent operator room could be disturbing for team communication. Conclusions: In-scenario instruction is an essential component of simulation-based teamwork training that has been largely overlooked in previous research. The ways in which facilitators convey information about the simulated patient have the potential to shape the simulation activities and thereby serve different learning goals. Although immediate timing to maintain an adequate pace is necessary for professionals to engage in training of medical emergencies, novices may gain from a slower tempo to train complex clinical team tasks systematically. PMID- 29450025 TI - Improving the quality of transvaginal ultrasound scan by simulation training for general practice residents. AB - Background: Ultrasonography (US) is an essential tool for the diagnosis of acute gynecological conditions. General practice (GP) residents are involved in the first-line management of gynecologic emergencies. They are not familiar with US equipment. Initial training on simulators was conducted.The aim of this study was to evaluate the impact of simulation-based training on the quality of the sonographic images achieved by GP residents 2 months after the simulation training versus clinical training alone. Methods: Young GP residents assigned to emergency gynecology departments were invited to a one-day simulation-based US training session. A prospective controlled trial aiming to assess the impact of such training on TVS (transvaginal ultrasound scan) image quality was conducted. The first group included GP residents who attended the simulation training course. The second group included GP residents who did not attend the course. Written consent to participate was obtained from all participants. Images achieved 2 months after the training were scored using standardized quality criteria and compared in both groups. The stress generated by this examination was also assessed with a simple numeric scale. Results: A total of 137 residents attended the simulation training, 26 consented to participate in the controlled trial. Sonographic image quality was significantly better in the simulation group for the sagittal view of the uterus (3.6 vs 2.7, p = 0.01), for the longitudinal view of the right ovary (2.8 vs 1.4, p = 0.027), and for the Morrison space (1.7 vs 0.4, p = 0.034), but the difference was not significant for the left ovary (2.9 vs 1.7, p = 0.189). The stress generated by TVS after 2 months was not different between the groups (6.0 vs 4.8, p = 0.4). Conclusion: Simulation-based training improved the quality of pelvic US images in GP residents assessed after 2 months of experience in gynecology compared to clinical training alone. PMID- 29450028 TI - Implementation of a novel synchronous multi-site all day high-fidelity simulation. AB - Integration of simulation in educational curricula for anesthesia and intensive care residents is a hot topic. There is a great interest for simulation centers to share their experiences through multi-site synchronous simulation sessions. The present study results from an experience conducted at three sites in France (Paris, Lyon, and Caen), which involved 16 instructors and 25 residents facing the same scenario across 1 day. Synchronous simulations were performed at each site with local and shared debriefing via teleconference. This innovative approach to simulation was found to be feasible, although certain difficulties were encountered with connectivity. PMID- 29450027 TI - Faculty development through simulation-based education in physical therapist education. AB - Background: The use of simulation-based education (SBE) in health professions, such as physical therapy, requires faculty to expand their teaching practice and development. The impact of this teaching on the individual faculty member, and how their teaching process changes or develops, is not fully understood. The purpose of this study was to explore individual physical therapist faculty members' experience with SBE and how those experiences may have transformed their teaching practice to answer the research questions: How do physical therapist faculty develop through including SBE and are there commonalities among educators? Methods: An interpretive phenomenological analysis approach was used with a small sample of subjects who participated in three individual semi structured interviews. Interview questions were created through the lens of transformative learning theory to allow faculty transformations to be uncovered. A two-step thematic coding process was conducted across participants to identify commonalities of faculty experiences with SBE in physical therapist education. Credibility and trustworthiness were achieved through member checking and expert external review. Thematic findings were validated with transcript excerpts and research field notes. Results: Eight physical therapist faculty members (25% male) with a range of 3 to 16 years of incorporating SBE shared their individual experiences. Four common themes related to faculty development were identified across the participants. Themes identified are the following: faculty strengthen their professional identity as physical therapists, faculty are affected by their introduction and training with simulation, faculty develop their interprofessional education through SBE, and faculty experiences with SBE facilitate professional growth. Conclusion: Physical therapist educators had similarities in their experiences with SBE that transformed their teaching practice and professional development. This study provides insight into what physical therapist faculty may experience when adopting SBE. PMID- 29450029 TI - Preface: a new stage in the evolution of public health reviews. PMID- 29450030 TI - Foundational values for public health. AB - The development of an agreed-upon set of foundational ethical values for the field of public health is ongoing. In this paper we outline key elements of recent convergence on some basic moral precepts that drive public health. We suggest that three elements are particularly useful for anchoring public health practitioners' reflections on public health ethics: 1) the notions of "common" and "professional" morality, 2) an understanding of the practice and content of modern public health and especially its practical, solution-focused orientation, and 3) an appreciation of the history of public health as integrally linked to evolving and contested views of the relationship between citizens, science, and the state. There is broad agreement that governments are stewards of their populations and are responsible for providing conditions that allow for its members to be healthy and productive. Given the role of policy and government in public health, the role of political philosophy likely has a substantial place as we seek a coherent system of ethical justification in our work. The aim here is not to align with one theoretical approach or another, rather, to consider the foundational values of public health practice order to identify the common moral governance of our work. Our profession's morality-the set of norms shared by all public health professionals-is determined by what public health is and what we think it should be. As our aspirations for public health evolve, it is incumbent upon us to engage in reflective discourse to reach a new equilibrium about our moral foundation. PMID- 29450031 TI - Towards public health ethics. AB - Health is a value, both objective and subjective, yet it is not the only value that contributes to the well-being of persons. In public health, there are different connotations of the term "public" relevant from an ethical perspective: population, government action, and collective action of the community. Ethics seeks to provide a basis for and justify moral decisions and actions. Ethics asks, why should I do it?, and the reply consists of an argument. The type of ethics that underpins applied ethics in general, and bioethics in particular, is civic ethics, a philosophical reflection on the criteria that enable the peaceful coexistence of citizens with different morals. Progress means emancipation as well as an increase of autonomy. However, more is not always better, and now we know that no health intervention, including a public health intervention, is risk free. The false belief that undergoing a prevention intervention is always better than doing nothing explains, at least in part, that in contrast to bioethics, only recently have the ethical implications in public health practice been given the attention they deserve. Positive externalities in third parties, such as in vaccination programmes or policies to prevent harm to passive smokers, can occasionally justify the potential risks of a public health intervention. It is in such situations where a conflict might arise between the goal of improving the health of the population and the respect for the rights and freedoms of the individual that characterizes the dilemmas in public health ethics. In conclusion, it is necessary to have a public health ethics framework and a professional code of ethics applied to public health. The training of public health professionals in ethics is essential to ensure that they feel more confident when it comes to addressing the sheer range of ethical conflicts that they frequently face in the performance of their duties. PMID- 29450032 TI - Integrating ethics in public health education: the process of developing case studies. AB - The study of ethics in public health became a societal imperative following the horrors of pre World War II eugenics, the Holocaust, and the Tuskegee Experiment (and more recent similar travesties). International responses led to: the Nuremberg Doctors' Trials, the Universal Declaration of Human Rights (1948), and the Convention on Prevention and Punishment of the Crime of Genocide (CCPCG, 1948), which includes sanctions against incitement to genocide. The Declaration of Geneva (1948) set forth the physician's dedication to the humanitarian goals of medicine, a declaration especially important in view of the medical crimes which had just been committed in Nazi Germany. This led to a modern revision of the Hippocratic Oath in the form of the Declaration of Helsinki (1964) for medical research ethical standards, which has been renewed periodically and adopted worldwide to ensure ethical research practices. Public health ethics differs from traditional biomedical ethics in many respects, specifically in its emphasis on societal considerations of prevention, equity, and population-level issues. Health care systems are increasingly faced with the need to integrate clinical medicine with public health and health policy. As health systems and public health evolve, the ethical issues in health care also bridge the gap between the separation of bioethics and public health ethics in the past. These complexities calls for the inclusion of ethics in public health education curricula and competencies across the many professions in public health, in the policy arena, as well as educational engagement with the public and the lay communities and other stakeholders. PMID- 29450033 TI - Continuing the conversation about public health ethics: education for public health professionals in Europe. PMID- 29450034 TI - An ethics training specific for European public health. AB - Training in public health ethics is not at the core of public health programmes in Europe. The fruitful progress of the United States could stimulate the European schools of public health and other academic institutions to develop specifically European teaching programmes for ethics that embrace both transatlantic innovations and some adaptations based on the evolution of moral values in European societies. This paper reviews the arguments for a European public health ethics curriculum and recommends the main features of such a programme. Europe shares common values and, above all, the three major ethical principles that were socially and politically crystallized by the French Revolution: liberty, equality, and fraternity. Fraternity, otherwise known as solidarity, although rarely mentioned in the literature on ethical issues, is the moral value that best defines the European concept of public health expressed as a common good, mutual aid, and a collective or shared responsibility for health of the population. Specific political motivations were responsible for the origin of European health systems and for current policy proposals led by the European Union, such as Europe's commitments, at least in theory, to: reduce social inequities in health and to develop the health in all policies approach. These and other initiatives, albeit not exclusively European, have political and legal repercussions that pose unique ethical challenges. Europe combines homogeneity in social determinants of health with heterogeneity in public health approaches and interventions. It is therefore necessary to develop training in ethics and good government for all public health workers in Europe, especially since a large segment of the population's health depends on actions and decisions adopted by the European Commission and its regulatory agencies as well as for non EU European Region countries. Based on these arguments, the paper concludes with several recommendations for a common nucleus for the ethics curriculum in Europe. PMID- 29450035 TI - Developing public health ethics learning modules - can we learn from critical pedagogy? AB - Curriculum development in masters of public health programs that effectively meets the complex ethical challenges of the 21st century is an important part of public health education and requires ethical reasoning and purposively thinking. Current master programs in Public Health do not regularly include modules in public health ethics. The aim of this paper is to present background and theoretical foundation for developing a methodology and methods to develop public health ethics modules for curriculum development in public health programs. We describe ethical reasoning in medicine and in Public Health, specify pedagogical approaches and key assignments organized around the critical pedagogy. PMID- 29450036 TI - Screening and overdiagnosis: public health implications. AB - Overdiagnosis is the diagnosis of an abnormality that bears no substantial health hazard and no benefit for patients to be aware of. Resulting mainly from the use of increasingly sensitive screening and diagnostic tests, as well as broadened definitions of conditions requiring an intervention, overdiagnosis is a growing but still largely misunderstood public health issue. Fear of missing a diagnosis or of litigation, financial incentives or patient's need of reassurance are further causes of overdiagnosis. The main consequence of overdiagnosis is overtreatment. Treating an overdiagnosed condition bears no benefit but can cause harms and generates costs. Overtreatment also diverts health professionals from caring for those most severely ill. Recognition of overdiagnosis due to screening is challenging since it is rarely identifiable at the individual level and difficult to quantify precisely at the population level. Overdiagnosis exists even for screening of proven efficacy and efficiency. Measures to reduce overdiagnosis due to screening include heightened sensitization of health professionals and patients, active surveillance and deferred treatment until early signs of disease progression and prognosis estimation through biomarkers (including molecular) profiling. Targeted screening and balanced information on its risk and benefits would also help limit overdiagnosis. Research is needed to assess the public health burden and implications of overdiagnosis due to screening activity. PMID- 29450037 TI - Screening for cardiovascular disease risk factors beginning in childhood. AB - Cardiovascular diseases (CVD) are the leading cause of death worldwide. Individual detection and intervention on CVD risk factors and behaviors throughout childhood and adolescence has been advocated as a strategy to reduce CVD risk in adulthood. The U.S. National Heart, Lung, and Blood Institute (NHLBI) has recently recommended universal screening of several risk factors in children and adolescents, at odds with several recommendations of the U.S. Services Task Force and of the U.K. National Screening committee. In the current review, we discuss the goals of screening for CVD risk factors (elevated blood pressure, abnormal blood lipids, diabetes) and behaviors (smoking) in children and appraise critically various screening recommendations. Our review suggests that there is no compelling evidence to recommend universal screening for elevated blood pressure, abnormal blood lipids, abnormal blood glucose, or smoking in children and adolescents. Targeted screening of these risk factors could be useful but specific screening strategies have to be evaluated. Research is needed to identify target populations, screening frequency, intervention, and follow-up. Meanwhile, efforts should rather focus on the primordial prevention of CVD risk factors and at maintaining a lifelong ideal cardiovascular health through environmental, policy, and educational approaches. PMID- 29450038 TI - Why and how would we implement a lung cancer screening program? AB - For decades, lung cancer has been the most common cancer in terms of both incidence and mortality. There has been very little improvement in the prognosis of lung cancer. Early treatment following early diagnosis is considered to have potential for development. The National Lung Screening Trial (NLST), a large, well-designed randomized controlled trial, evaluated low-dose computed tomography (LDCT) as a screening tool for lung cancer. Compared with chest X-ray, annual LDCT screening reduced death from lung cancer and overall mortality by 20 and 6.7 %, respectively, in high-risk people aged 55-74 years. Several smaller trials of LDCT screening are under way, but none are sufficiently powered to detect a 20 % reduction in lung cancer death. Thus, it is very unlikely that the NLST results will be replicated. In addition, the NLST raises several issues related to screening, such as the high false-positive rate, overdiagnosis and cost. Healthcare providers and systems are now left with the question of whether the available findings should be translated into practice. We present the main reasons for implementing lung cancer screening in high-risk adults and discuss the main issues related to lung cancer screening. We stress the importance of eligibility criteria, smoking cessation programs, primary care physicians, and informed-decision making should lung cancer screening be implemented. Seven years ago, we were waiting for the results of trials. Such evidence is now available. Similar to almost all other cancer screens, uncertainties exist and persist even after recent scientific efforts and data. We believe that by staying within the characteristics of the original trial and appropriately sharing the evidence as well as the uncertainties, it is reasonable to implement a LDCT lung cancer screening program for smokers and former smokers. PMID- 29450039 TI - On the rationale of population screening for chronic kidney disease: a public health perspective. AB - Unlike opportunistic screening, population screening is accompanied by stringent quality control measures and careful programme monitoring. Sufficient evidence for benefit together with acceptable harms and costs to society are needed before launching a programme. A screening programme is a complex process organized at the population level involving multiple actors of the health care system that should ideally be supervised by public health authorities and evaluated by an independent and trustful body. Chronic kidney disease is defined by reduced glomerular filtration rate and/or presence of kidney damage for at least three months. Chronic kidney disease is divided into 5 stages with stages 1 to 3 being usually asymptomatic. Chronic kidney disease affects one in ten adults worldwide and its prevalence sharply increases with age. Kidney function is measured using serum creatinine-based, and/or cystatin C-based, equations. Markers of renal function show high intra-individual and inter-laboratory variabilities, highlighting the need for standardized procedures. There is also large inter individual variability in age-related kidney function decline. Despite these limitations, chronic kidney disease, as currently defined, has been consistently associated with high cardiovascular morbidity and mortality and high risk of end stage renal disease. Major modifiable risk factors for chronic kidney disease are diabetes, hypertension, obesity and cardiovascular disease. Several treatment options, ranging from antihypertensive and lipid-lowering treatments to dietary measures, reduce all-cause mortality and/or end-stage renal disease in patients with stages 1-3 chronic kidney disease. So far, no randomized controlled trial comparing outcomes with and without population screening for stages 1-3 chronic kidney disease has been published. Population screening for stages 1-3 chronic kidney disease is currently not recommended because of insufficient evidence for benefit. Given the current and future burden attributable to chronic kidney disease, randomized controlled trials exploring benefits and harms of population screening are clearly needed to prioritize resource allocations. PMID- 29450040 TI - Teaching public health ethics. AB - Teaching public health ethics has been recognised as patchy and somewhat theoretically incoherent for some years. Despite Beauchamp and Childress' work being widely known and used within health care its various principles have been criticised by a number of writers for, among other things, their inherent cultural relativism. This article suggests how a broader ethically oriented approach to the ever-changing field of public health might be pursued - so that a professional public health practitioner might be prepared for a lifelong career of ethical activism. Informed by the pedagogic philosophy of Freire it assumes the development of a module within an MPH programme. If, as is widely acknowledged, we are dealing with essentially a corpus of values, the challenge for an educator of public health ethics is how do we inculcate those values effectively and efficiently? How do we prepare students for as yet unrecognised ethical problems that they might confront? How do we assess such teaching? We know that even in clinical practice gaps appear between accepted ethical principles and actual practice. Within public health the conflicts generated by rival claimants and the contradictions of applying principles at a societal level become even clearer as action to control a situation might restrict the rights of others. This makes it even more important that students are exposed to learning experiences which will equip them adequately for a lifetime of practice. Traditional didactic approaches need to be supplemented with additional modalities such as case studies and role playing. Such case studies might encompass macro policy issues or micro operational issues. Other approaches could include citizen juries, examining international agreements and codes of practice, debates and encouraging explicit reflective practices. The importance of repetition, teachers as role models, courses which themselves demonstrate ethical practice, and a variety of methods are emphasized. PMID- 29450041 TI - Screening for cardiovascular disease risk and subsequent management in low and middle income countries: challenges and opportunities. AB - Background: Cardiovascular disease (CVD), mainly heart attack and stroke, is the leading cause of premature mortality in low and middle income countries (LMICs). Identifying and managing individuals at high risk of CVD is an important strategy to prevent and control CVD, in addition to multisectoral population-based interventions to reduce CVD risk factors in the entire population. Methods: We describe key public health considerations in identifying and managing individuals at high risk of CVD in LMICs. Results: A main objective of any strategy to identify individuals at high CVD risk is to maximize the number of CVD events averted while minimizing the numbers of individuals needing treatment. Scores estimating the total risk of CVD (e.g. ten-year risk of fatal and non-fatal CVD) are available for LMICs, and are based on the main CVD risk factors (history of CVD, age, sex, tobacco use, blood pressure, blood cholesterol and diabetes status). Opportunistic screening of CVD risk factors enables identification of persons with high CVD risk, but this strategy can be widely applied in low resource settings only if cost effective interventions are used (e.g. the WHO Package of Essential NCD interventions for primary health care in low resource settings package) and if treatment (generally for years) can be sustained, including continued availability of affordable medications and funding mechanisms that allow people to purchase medications without impoverishing them (e.g. universal access to health care). This also emphasises the need to re-orient health systems in LMICs towards chronic diseases management. Conclusion: The large burden of CVD in LMICs and the fact that persons with high CVD can be identified and managed along cost-effective interventions mean that health systems need to be structured in a way that encourages patient registration, opportunistic screening of CVD risk factors, efficient procedures for the management of chronic conditions (e.g. task sharing) and provision of affordable treatment for those with high CVD risk. The focus needs to be in primary care because that is where most of the population can access health care and because CVD programmes can be run effectively at this level. PMID- 29450042 TI - Prevalence of hypertension in Ethiopia: a systematic meta-analysis. AB - Background: Hypertension has been increasing in developing countries including Ethiopia. Other than smaller studies, there is no national prevalence study on hypertension in Ethiopia. These smaller studies reported varied prevalence of hypertension. This study is intended to summarize and pool the results of smaller region based studies to provide a national level estimate of the prevalence of hypertension. Methods: The studies were identified through internet search using the data base of MEDLINE/PubMed, Google scholar, EMBASE, HINARI, Cochrane library and reference lists of previous prevalence studies. We also made manual searches to identify relevant articles. Descriptive information for the original studies is presented in a table and the quantitative results were presented in forest plots. The Cochrane Q test and I2 test statistic were used to test heterogeneity across studies. The Pooled estimate of prevalence of hypertension was computed by a random effects model. Results: One hundred eight titles were identified through electronic searching using keywords. Of these, nine studies were meet the inclusion criteria. A random effect meta-analysis of the results from these 9 studies was conducted to provide an estimate of the prevalence of hypertension in the Ethiopian population. The analysis showed that the prevalence of hypertension among Ethiopian population was estimated to be 19.6 % (95 % CI: 13.7 %, 25.5 %). Subgroup analyses indicated that the prevalence of hypertension is higher in the urban population (23.7 %) than rural and urban combined (14.7 %). The prevalence of hypertension among males (20.6 %) and females (19.2 %) was similar. Conclusion: This study found that the prevalence of hypertension in Ethiopia is increasing. This evidence suggests that attention has to be given to primary prevention of hypertension in the Ethiopian adult population, especially in the urban population by integrating it with health extension programs. PMID- 29450043 TI - Europe's collective failure to address the refugee crisis. AB - The European response to the refugee crisis has been lamentable. A preoccupation with numbers has, too often, ignored how each refugee is an individual, many of whom have experienced the most appalling conditions in their countries of origin and in transit. These stories are only rarely heard, when the cameras are there to capture the tragedies. In this commentary we review the challenges of responding to the health needs of refugees, including examples of best practice, but above all call for a concerted political response that will both reduce the pressure on refugees to flee conflict-afflicted countries and recognize their contribution if they do come to Europe. PMID- 29450044 TI - Creating conditions for Canadian aboriginal health equity: the promise of healthy public policy. AB - In the Canadian context, the persistence and growth of Aboriginal health and social inequity signals that we are at a critical public health policy juncture; current policy reflects an historic relationship between Aboriginal people and Canada that fails the contemporary health needs of Canada's Aboriginal peoples. In this review, we highlight the need for healthy public policy that recognizes and prioritizes the rights of Canada's Aboriginal people to achieve health equity. Drawing from a structural approach, we examine the historical scope and comprehensive breadth of the Indian Act in shaping modern Aboriginal health and social inequities. Canada's failure to implement a national public policy for Aboriginal health reflects the proliferation of racism in modern day Canada, and a distinctly lacking political will at the federal level. Despite these structural challenges, there is great promise in community self-determination in health care and the role of community-led research as advocacy for policy reform. In our conclusion, we turn to the Report on the Truth and Reconciliation Commission of Canada (2015) and draw upon the concept of reconciliation as a fundamental precursor for Aboriginal health equity. The burden of systemic change needed to promote healthy public policy cannot be carried by any single group of advocates; it is a shared responsibility that will require the collaboration and integration of various actors and knowledges. PMID- 29450045 TI - Nutritional rickets in immigrant and refugee children. AB - Immigrant and refugee populations bring public health challenges to host nations. In the current global refugee crisis, children are the most vulnerable subpopulation. Diseases that were considered rare in the host nation may be highly prevalent among immigrant children. The prevalence of nutritional rickets is increasing in high-income countries, largely driven by an influx of immigrant populations. Nutritional rickets is a bone disease in early childhood resulting in bone pain, delayed motor development, and bending of the bones, caused by vitamin D deficiency and/or inadequate dietary calcium intake. The consequences of nutritional rickets include stunted growth, developmental delay, lifelong bone deformities, seizures, cardiomyopathy, and even death. Nutritional rickets is most commonly seen in children from the Middle East, Africa, and South Asia in high-income countries. Dark skin pigmentation, sun avoidance, covering the skin, and prolonged breast feeding without vitamin D supplementation, are important risk factors for vitamin D deficiency, and combined with a lack of dairy products in the diet, these deficiencies can result in insufficient calcium supply for bone mineralization. We recommend screening all immigrant and refugee children under 5 years of age from these ethnic groups for nutritional rickets, based on clinical features, and confirming the diagnosis with radiographs of the wrists and knees. Because nutritional rickets is entirely preventable, public health policies must address the need for universal vitamin D supplementation and adequate dietary calcium to protect children from this scourge. Vitamin D supplementation of all infants and children with 400 IU/d during the first year of life and dietary or supplemental intakes of at least 600 IU/d of vitamin D and 500 mg/d of calcium thereafter, will effectively prevent nutritional rickets. We call on national health authorities of host countries to implement health check lists and prevention programs that include screening for micronutrient deficiencies, in addition to assessing infections and vaccination programs. Due to their high prevalence of vitamin D deficiency, refugee children of all ages from these ethnic groups should be supplemented with vitamin D, beginning upon arrival. PMID- 29450047 TI - Access to healthcare for undocumented migrants in France: a critical examination of State Medical Assistance. AB - In France in 2012, of the total population of 65.2 million, 8.7 % were migrants. After being the third principal host country, France is now the 6th highest host country in the OECD. Since the 1980's numerous Acts have been passed by parliament on immigration issues. In 2000 the Universal Health Cover (Couverture Maladie Universelle) was created as health coverage for all residents of France. At the same time the State Medical Assistance (Aide Medicale de l'Etat) was created as health protection for undocumented migrants. Since the creation of this scheme, it has been the object of many political debates which call it into question, on account of its cost, perceived fraud, and the legitimacy of a social protection for undocumented migrants. Recently, access to State Medical Assistance has been made difficult by introducing conditions of residence and financial contributions. After a reports' analysis on institutional, associative, research studies and European recommendations, we note that all reports converge on the necessity of health protection for undocumented migrants. The major reasons are humanitarian, respect of European and International conventions, for public health, and financial. Moreover, fraud allegations have proved to be unfounded. Finally, State Medical Assistance is underused: in 2014 data from Medecins du Monde shows that only 10.2 % of undocumented migrant patients in their health facilities have access to this scheme. We conclude that the political debate concerning the State Medical Assistance should be about its under-utilisation, its improvement, its merger with the Universal Health Cover, and not its elimination. Moreover, the current debates regarding this scheme stigmatize this population, which is already precarious, making it more difficult for migrants to access healthcare, and generally, weaken national social cohesion. PMID- 29450046 TI - Social and health epidemiology of immigrants in Germany: past, present and future. AB - Germany has experienced different forms of immigration for many decades. At the end of and after the Second World War, refugees, displaced persons and German resettlers constituted the largest immigrant group. In the 1950s, labor migration started, followed by family reunification. There has been a constant migration of refugees and asylum seekers reaching peaks in the early 1990s as well as today. Epidemiological research has increasingly considered the health, and the access to health care, of immigrants and people with migration background. In this narrative review we discuss the current knowledge on health of immigrants in Germany. The paper is based on a selective literature research with a focus on studies using representative data from the health reporting system. Our review shows that immigrants in Germany do not suffer from different diseases than non immigrants, but they differ in their risk for certain diseases, in the resources to cope with theses risk and regarding access to treatment. We also identified the need for differentiation within the immigrant population, considering among others social and legal status, country of origin and duration of stay. Though most of the studies acknowledge the need for differentiation, the lack of data currently rules out analyses accounting for the existing diversity and thus a full understanding of health inequalities related to migration to Germany. PMID- 29450048 TI - The need for a rights-based public health approach to Australian asylum seeker health. AB - Public health professionals have a responsibility to protect and promote the right to health amongst populations, especially vulnerable and disenfranchised groups, such as people seeking asylum and whose health care is frequently compromised. As at 31 March 2016, there was a total of 3707 people (including 384 children) in immigration detention facilities or community detention in Australia, with 431 of them detained for more than 2 years. The Public Health Association of Australia and the Australian Medical Association assert that people seeking asylum in Australia have a right to health in the same way as Australian citizens, and they denounce detention of such people in government facilities for prolonged and indeterminate periods of time. The position of these two professional organisations is consistent with the compelling body of evidence demonstrating the negative impact detention has on health. Yet in recent years, both the Labour and Liberal parties-when at the helm of Australia's Federal Government-have implemented a suite of regressive policies toward individuals seeking asylum. This has involved enforced legal restrictions on dissenting voices of those working with these populations, including health professionals. This paper outlines Australia's contemporary offshore immigration detention policy and practices. It summarises evidence on asylum seeker health in detention centres and describes the government's practice of purposeful silencing of health professionals. The authors examine how Australia's treatment of asylum seekers violates their health rights. Based on these analyses, the authors call for concrete action to translate the overwhelming body of evidence on the deleterious impacts of immigration detention into ethical policy and pragmatic interventions. To this end, they provide four recommendations for action. PMID- 29450050 TI - The role of funders: Wellcome Trust. AB - Wellcome exists to improve health for everyone by helping great ideas to thrive. We are a global charitable foundation, both politically and financially independent. We support scientists and researchers take on big problems, fuel imaginations and spark debate. The health of the global population and the planet are inextricably linked but there is a poor ecological fit between what we are asking of the planet and its resilience. If the complex natural systems we rely on for clean air, fresh water, fertile soil, biodiversity and a stable climate are threatened, so too is our health. The challenge is to secure the health and well-being of present and future generations whilst responsibly stewarding the planet. As research continues to unravel our understanding of the vital links between health and the environment, we become better equipped to develop robust, coherent and coordinated solutions that jointly reduce threats to human health and to the surrounding environment that sustains it. There are already clear opportunities for change but more research is needed. Our Planet, Our Health was identified as new priority area for Wellcome in 2015. We support work that embraces and stimulates creative partnerships, collaborating across disciplines and sectors, because we believe that we need a diversity of competencies to tackle these complex problems. Our aim is to gain deeper insights into these issues, to inform the global response through transdisciplinary research and develop policies that will help mitigate the risks to human health. PMID- 29450051 TI - Migrants and health in the Nordic welfare states. AB - This article probes into the health of migrants with a focus on the situation in the Nordic universal welfare states. The Nordic welfare states are further compared to each other with a comparison to the EU28 if possible, including investigation of the differences among the four Nordic countries. This is done by analyzing central parameters related to access to and inequality in health care. The article concludes that ethnicity does not give rise by itself to differences in health care, including access to care, but can be seen as a marker of where health problems might arise due to other specific socioeconomic factors, such as the impact of economic inequality. Moreover, the healthy migrant paradox cannot be confirmed. PMID- 29450049 TI - Screening for frailty: older populations and older individuals. AB - The concept of frailty as a health dimension in old age is recent and has its origin in the development of geriatric medicine. Initially an unformulated clinical intuition, it is now defined by a diminished physiological reserve of multiple organs that exposes older individuals to increased vulnerability to stressors and a higher risk of adverse outcomes. The operational definition of frailty, however, is still debated. From a diversity of models, two emerged in the early 2000s from epidemiological studies conducted in large population-based aging cohorts. The body of research emphasized prospective associations between a frailty phenotype and a range of adverse outcomes or between a frailty index measuring the accumulation of deficits and death. A few studies showed promising spontaneous remissions in the early stages of frailty, raising expectations for effective interventions. Transitions between frailty stages and effective interventions on frailty nevertheless remain two fields needing further investigation. More recently, these tools have been applied as screening instruments in clinical settings to guide individual decision-making and orient treatments. New questions are raised by the use of instruments developed to screen frailty in epidemiological research for assessing individual situations. Inquiring whether frailty screening is relevant opens a Pandora's box of doubts and debates. There are many reasons to screen for frailty both from a public health and a clinical perspective that are only exacerbated by the current demographic evolution. Open questions remain about the feasibility of frailty screening, the properties of screening tools, the relevance of an integration of socioeconomic dimensions into screening tools, and the effectiveness of interventions targeting frailty. Fifteen years after the publication of the Fried and Rockwood landmark papers proposing operational definitions of frailty, this article presents an overview of current perspectives and issues around frailty screening in populations and in individuals. PMID- 29450052 TI - Refugee trauma measurement: a review of existing checklists. AB - Abstract: Studies have shown that a high proportion of refugees have been subjected to potentially traumatic experiences (PTEs). PTEs, including torture, are powerful predictors of mental ill health. This paper reports a review of refugee trauma history self-report measures used in population studies. Methods: A review of existing instruments and checklists, up to September 2015, was performed. Results: The types of measures for refugee trauma history vary from semi-structured interviews and medical records to extensive multi-item trauma checklists. The Harvard Trauma Questionnaire (HTQ) was the most commonly used instrument for measuring trauma history among refugee populations. Few checklists included PTEs during the flight. Conclusion: Trauma history checklists are often used as a tool to control for background variables when studying refugees' mental health and have mostly been developed in clinical or semi-clinical settings. There is a need for acceptable, reliable and valid brief checklists for measuring trauma in refugees, for the purpose of performing larger scale population studies.

AB - Background: Ethnic density (the proportion of ethnic minority populations in a geographic area) has emerged as an important factor determining population health. By examining the relationship between mortality rates and the proportion of aboriginal population in Taiwan, this ecological approach highlights the pressing need to understand why aboriginal health remains relatively disadvantaged affecting the population as a whole, especially given the provision of universal health coverage. Methods: Using combined data from various government departments in Taiwan, we first compare overall mortality rates between aboriginal people and the general population in Taiwan's 21 administrative locations during the years 2010 and 2011. Then we describe the associations between ethnic density and the relative risk of 40 different causes of death. Results: Aboriginal people in Taiwan on average have higher overall mortality rates than the general population. The proportion of aboriginal population is associated with a higher risk of death for overall mortality, homicide, vehicle crashes, tuberculosis, and several alcohol-related diseases such as peptic ulcer, chronic liver disease, and cirrhosis. These affect the health of the general population in counties where aborigines are abundant. Conclusion: The proportion of aboriginal population may play an essential role in determining Taiwan's population health. When universal health coverage is in place, the root causes (for example, alcoholism, culture, and socioeconomic disadvantages) of health disparities between aboriginal populations and general populations need to be addressed.

AB - Using a modified social ecological model, we conducted a review of the literature and nationwide statistics on African American health. We discuss the main social determinants of health and main health disparities, risk factors, the leading causes of morbidity and mortality, and access to health services for blacks in the USA. The mechanisms through which social determinants, including racism, exert their deleterious effects on black health are discussed at the macro and individual levels. Incarceration and mental health care issues are highlighted as priorities to be addressed. African Americans remain the least healthy ethnic group in the USA, a somber legacy of years of racial and social injustice and a formidable challenge to equitable health care for all. Systemic causes of suboptimal black health require equally systemic solutions; positive trends in black health indicators seem to be driven by social development programs, economic investment in education, participation of African Americans in policy, and decision-making and expansion of access to health care. PMID- 29450056 TI - Addressing challenges to human health in the Anthropocene epoch-an overview of the findings of the Rockefeller/Lancet Commission on Planetary Health. AB - The report of the Rockefeller Foundation/Lancet Commission on Planetary Health described how human health directly depends upon the environment. It takes a broad perspective not only acknowledging climate change as the most important global environmental threat to health but also recognizing other impacts, including dramatic loss of tropical forests, land degradation, loss of biodiversity, declining freshwater resources, ocean acidification, and over exploitation of fisheries. All pose challenges to human health gains, leading to the concept of planetary health-that the human condition is tied to natural systems. The Planetary Health Commission report highlights several major concerns arising from environmental change including impacts on food availability and quality, increases in natural disasters and population displacement, and newly emerging diseases, e.g. from zoonotic infections. Three challenges emerge from the report: the first is imagination, or conceptual challenges-better metrics are needed to assess human progress within the context of environmental change; the second is a lack of relevant knowledge, requiring more research on the inter linkages between environmental change and health and on the effectiveness of potential solutions; and the third is implementation of solutions, ensuring that the science is translated into policy and practice. There are many opportunities to promote planetary health including developing sustainable and healthy cities, encouraging more resilient health systems and disaster preparedness, reducing food waste, preserving ecosystems, and redirecting harmful subsidies in food, agriculture, fishery and energy sectors. Many current trends are driven by inequitable, inefficient, and unsustainable patterns of resource consumption and technological development, coupled with population growth, but solutions lie within reach. Prosperity must be redefined as an enhancement of the quality of life and the delivery of improved health for all, together with respect for natural systems. PMID- 29450055 TI - Are undocumented migrants' entitlements and barriers to healthcare a public health challenge for the European Union? AB - Undocumented migrants (UMs) are at higher risk for health problems because of their irregular status and the consequences of economic and social marginalization. Moreover, the emergent reality of undocumented migration in Europe calls for action in the field of management of UM's health demands as their access to health services has become a sensitive political and social issue. In this light, this paper aims to address UMs' entitlement and barriers to healthcare and related policies citing evidence from peer-reviewed and grey literature concerning people living in a country within the European Union without the legal right to be/remain in the destination country. A systematic review was performed using several databases and websites, and a total of 54 publications in English, with full text available, were taken into consideration. Between 2000 and 2015, Europe hosted the second largest number of international migrants (20 million, 1.3 million per year) after Asia. Even though there is limited evidence specifically focused on UMs' health, it is possible to state that infectious diseases, chronic illnesses, mental disorders, maternal-child conditions, dental issues, acute illnesses and injuries are the most common pathologies. In most cases across Europe, UMs have access only to emergency care. Even in countries where they are fully entitled to healthcare, formal and informal barriers hinder them from being or feeling entitled to this right. Socio cultural barriers, such as language and communication problems, lack of formal and informal social and healthcare networks and lack of knowledge about the healthcare system and about informal networks of healthcare professionals are all common impediments. From the healthcare providers' perspective, there can be difficulties in providing appropriate care and in dealing with cultural and language barriers and false identification. Communication strategies play a central role in addressing the inequalities in access to healthcare services, and the definition and provision of specific training, focused on UMs' health needs, would be desirable. Improving access to healthcare for UMs is an urgent priority since the lack of access is proven to have serious consequences for UMs' health and wellbeing. Notwithstanding, few available examples of policies and best practices aimed at overcoming barriers in the delivery of healthcare to UMs are available.

AB - The right to health of migrant populations, whether they are foreign nationals, foreign workers, tourists, asylum seekers or refugees, is enshrined in international human rights treaties. The effectiveness of the implementation of this fundamental right thus lies in national legal frameworks. In spite of its long humanitarian tradition, Switzerland has a strict migration policy, and while it has established a non-discriminatory legal framework for the protection and promotion of the right to health, its laws and regulations sometimes codify differences in treatment between foreign nationals and Swiss residents based on distinct situations. On the basis of shared responsibilities between the Federal State and the 26 cantons, this article describes the Swiss legal and regulatory approach to the right to health, the ways it is currently implemented and the possible vectors for an improved integration of migrants into the health system. PMID- 29450058 TI - NUTRItion and CLIMate (NUTRICLIM): investigating the relationship between climate variables and childhood malnutrition through agriculture, an exploratory study in Burkina Faso. AB - Malnutrition remains a leading cause of death in children in low- and middle income countries; this will be aggravated by climate change. Annually, 6.9 million deaths of children under 5 were attributable directly or indirectly to malnutrition. Although these figures have recently decreased, evidence shows that a world with a medium climate (local warming up to 3-4 degrees C) will create an additional 25.2 million malnourished children. This proof of concept study explores the relationships between childhood malnutrition (more specifically stunting), regional agricultural yields, and climate variables through the use of remote sensing (RS) satellite imaging along with algorithms to predict the effect of climate variability on agricultural yields and on malnutrition of children under 5. The success of this proof of purpose study, NUTRItion and CLIMate (NUTRICLIM), should encourage researchers to apply both concept and tools to study of the link between weather variability, crop yield, and malnutrition on a larger scale. It would also allow for linking such micro-level data to climate models and address the challenge of projecting the additional impact of childhood malnutrition from climate change to various policy relevant time horizons. PMID- 29450059 TI - Adaptation and resilience. AB - Lessons learned, opportunities, and barriers to scaling up health adaptation were identified from evaluation reports and other materials from three multinational health adaptation projects covering 14 low- and middle-income countries and from qualitative data collected through a focus group consultation and interviews with key informants purposively selected for their expertise and role in health adaptation. The national projects aimed to increase resilience to climate sensitive health outcomes by focusing on incremental improvements in policies and programs to address climate variability and by beginning to establish enabling environments for further adaptation. At this early stage in implementing health adaptation, projects have made limited plans for scaling up specific health adaptation activities outside of normal ministry approaches. Scaling up is needed to prepare for the challenges ahead, including by improving integrated surveillance and other programs to manage the health risks of a changing climate. PMID- 29450060 TI - Why should health be a central argument in climate negotiations? Can a MOOC help to bring the message across? AB - There are four key messages from health for climate negotiations. Two positive ones include (i) health as a motivator for action and policy and (ii) huge health co-benefits to be included in the cost-benefit trade-offs of climate negotiations. Two warning messages: (iii) there are health-based absolute limits of adaptations and (iv) hotter average temperatures will cut work productivity of farmers and other outdoor workers as well as workers in non-air conditioned factories in poor countries. This paper will examine how massive open online courses (MOOCs) have been used in the run-up to this COP to disseminate these four messages to the audience of high-level policy-makers. This required a departure from the classic MOOC format in several ways: duration, focus on decision-making rationale, policy-relevant messages presented in big brush, leaving "traceable accounts" to evidence in two layers of resources provided: essential and "deep dive". PMID- 29450061 TI - International organizations and migrant health in Europe. AB - International organizations have defined and managed different aspects of migrant health issues for decades, yet we lack a systematic understanding of how they reach decisions and what they do on the ground. The present article seeks to clarify the state of knowledge on the relationship between international organizations and migrant health in Europe. To do so, we review the operations of six organizations widely recognized as key actors in the field of migrant health: the European Commission, the Regional Office for Europe of the World Health Organization, the International Organization on Migration, Medecins du Monde, Medecins Sans Frontieres, and the Open Society Foundation. We find that international organizations operate in a complementary fashion, with each taking on a unique role in migrant health provision. States often rely on international organizations as policy advisors or sub-contractors for interventions, especially in the case of emergencies. These linkages yield a complex web of relationships, which can vary depending on the country under consideration or the health policy issue in question. PMID- 29450062 TI - Aging and health among migrants in a European perspective. AB - Population aging and the associated changes in demographic structures and healthcare needs is a key challenge across Europe. Healthy aging strategies focus on ensuring the ability to maintain health, quality of life and independent living at old age. Concurrent to the process of population aging, the demographics of Europe are affected by increased migration resulting in substantial ethnic diversity. In this paper, we narratively review the health profile of the growing proportion of aging migrants in Europe, outline key factors shaping health among this diverse group and consider ways of addressing their healthcare needs. Although factors shaping aging processes are largely similar across populations, migrant-specific risk factors exist. These include exposure to health risks before and during migration; a more disadvantaged socioeconomic position; language barriers and low health literacy; cultural factors influencing health-seeking behaviours; and psychosocial vulnerability and discrimination affecting health and quality of life. Overall, migrants experience the same morbidity and mortality causes as the native populations, but with different relative importance, severity and age of onset and with substantial differences within and between migrant groups. Little is known regarding health behaviours among aging migrants, although differences in cancer screening behaviours have been identified. Indications of widening health differentials between migrants and native populations with age and informal barriers to quality healthcare for aging migrants are causes of concern. In conclusion, there is a need for attention to migration alongside other determinants of healthy aging. The diversity in individual characteristics, life course processes and contextual factors shaping aging processes among migrants point to the need for a sensitive and comprehensive approach to policies, practices and research within the field of healthy aging. This is important to accommodate for the needs of the growing number of aging migrants in Europe and counter inequities in health and well being at old age. PMID- 29450063 TI - Climate change and infectious diseases. AB - Global changes are major determinants for infectious diseases, although attributable, part of climate change remains debatable. Vector-borne diseases are prone to be impacted by global warming, although other factors may play a substantial role, evidenced by the dramatic decrease in malaria in the last decades in places where climate change has deep and significant effects. There is now evidence that in some areas of the world, e.g. Horn of Africa, warm El Nino Southern Oscillations (ENSO), which are observed in the South Pacific Ocean, are associated with higher risk of emergence of Rift Valley fever, cholera and malaria and during cold La Nina events, dengue fever, chikungunya and yellow fever. This has been observed for these and other diseases in other parts of the world. For example, seasonal influenza outbreaks have been more intense (i.e. higher number) and more severe (i.e. higher mortality) when concomitant with La Nina events. Since climate scientists have recently observed that climate change is tied to more frequent and more intense ENSO events, we may foresee increases in frequency and severity in emerging infectious diseases in the world. PMID- 29450064 TI - Sustainable, healthy cities: making the most of the urban transition. AB - The world is undergoing a massive urban transition, which is now both the greatest driver of global environmental change and the most significant influence on human health. Cities offer real opportunities for improving health, but managed poorly, they can also create or reinforce significant health deficits while putting severe stresses on the natural systems which support human civilization. Management of urban problems is rarely straightforward, as complexity across scales and sectors, in causal structures, actors and incentives, can lead to ineffective policies and unintended consequences. Systems thinking offers a promising way forward in its ability to deal with non-linear relationships and simultaneous actions and outcomes. Encompassing, on the one hand, analytic frameworks and methods that can provide important causal insights and a test bed for urban policy, and on the other, broad processes of inter- and trans-disciplinary engagement to better define problems and feasible solutions, systems approaches are critical to the current and future design and management of sustainable healthy cities. PMID- 29450065 TI - How do sustainable diets fit into the climate agenda? AB - Food production is a major driver of greenhouse gas (GHG) emission and other environmental footprints, and dietary risk factors are contributors to non communicable diseases. A growing body of evidence has shown that changes in what and how much we eat can offer benefits for both the environment and health. However, several data gaps and complexities remain in this research area. A better understanding and increased uptake of sustainable diets will require further research, investment, and interdisciplinary collaboration. PMID- 29450066 TI - Integrated mixed methods policy analysis for sustainable food systems: trends, challenges and future research. AB - Agriculture is a major contributor to greenhouse gas emissions, an important part of which is associated to deforestation and indirect land use change. Appropriate and coherent food policies can play an important role in aligning health, economic and environmental goals. From the point of view of policy analysis, however, this requires multi-sectoral, interdisciplinary approaches which can be highly complex. Important methodological advances in the area are not exempted from limitations and criticism. We argue that there is scope for further developments in integrated quantitative and qualitative policy analysis combining existing methods, including mathematical modelling and stakeholder analysis. We outline methodological trends in the field, briefly characterise integrated mixed methods policy analysis and identify contributions, challenges and opportunities for future research. In particular, this type of approach can help address issues of uncertainty and context-specific validity, incorporate multiple perspectives and help advance meaningful interdisciplinary collaboration in the field. Substantial challenges remain, however, such as the integration of key issues related to non-communicable disease, or the incorporation of a broader range of qualitative approaches that can address important cultural and ethical dimensions of food.

AB - Future Earth is an international research platform providing the knowledge and support to accelerate our transformations to a sustainable world. Future Earth 2025 Vision identified eight key focal challenges, and challenge #6 is to "Improve human health by elucidating, and finding responses to, the complex interactions amongst environmental change, pollution, pathogens, disease vectors, ecosystem services, and people's livelihoods, nutrition and well-being." Several studies, including the Rockefeller Foundation/Lancet Planetary Health Commission Report of 2015, the World Health Organization/Convention on Biological Diversity report and those by oneHEALTH (former ecoHEALTH), have been conducted over the last 30 years. Knowledge-Action Networks (KANs) are the frameworks to apply Future Earth principles of research to related activities that respond to societal challenges. Future Earth Health Knowledge-Action Network will connect health researchers with other natural and social scientists, health and environmental policy professionals and leaders in government, the private sector and civil society to provide research-based solutions based on better, integrated understanding of the complex interactions between a changing global environment and human health. It will build regional capacity to enhance resilience, protect the environment and avert serious threats to health and will also contribute to achieving Sustainable Development Goals. In addition to the initial partners, Future Earth Health Knowledge-Action Network will further nourish collaboration with other on-going, leading research programmes outside Future Earth, by encouraging them in active participation. PMID- 29450068 TI - Addressing planetary health challenges in Africa. AB - Drawing on the report of the Rockefeller Foundation-Lancet Commission on planetary health-Safeguarding human health in the Anthropocene epoch, this piece presents a discussion of the implications of the report's findings and conclusions for Africa. It explores the key planetary health challenges facing Africa and what Africa can do to address them. In addition to highlighting current and future trajectories of key environmental changes in Africa and their implications for health and well-being, this transcript from the 21st Conference of Parties (COP21) side event, "Healthy Lives on a Healthy Planet", identifies a set of priority action Africa needs to take in order to deal with these challenges. It ends with reflections and key recommendations from participants at the regional launch of the report in Nairobi, Kenya, in October 2015. PMID- 29450070 TI - The implications of COP21 for our future climate. AB - Rising CO2 in the atmosphere is the main cause of anthropogenic climate change, and the data shows a clear increase in global temperature of about 1 degrees C since pre-industrial levels. Changes in climate extremes are also occurring, with observed increases in the frequency of heat waves, in intense precipitation (rainfall and snowfall) in many places, and in sea level and storm surges. A changing climate with rising extremes has associated risks for food production and other health-related impacts. In order to limit climate change well below 2 degrees C, our carbon emissions must rapidly follow a decreasing trajectory to near zero. PMID- 29450069 TI - A systematic review of the use of health services by immigrants and native populations. AB - Background: Changes in migration patterns that have occurred in recent decades, both quantitative, with an increase in the number of immigrants, and qualitative, due to different causes of migration (work, family reunification, asylum seekers and refugees) require constant u pdating of the analysis of how immigrants access health services. Understanding of the existence of changes in use patterns is necessary to adapt health services to the new socio-demographic reality. The aim of this study is to describe the scientific evidence that assess the differences in the use of health services between immigrant and native populations. Methods: A systematic review of the electronic database MEDLINE (PubMed) was conducted with a search of studies published between June 2013 and February 2016 that addressed the use of health services and compared immigrants with native populations. MeSH terms and key words comprised Health Services Needs and Demands/Accessibility/Disparities/Emigrants and Immigrants/Native/Ethnic Groups. The electronic search was supplemented by a manual search of grey literature. The following information was extracted from each publication: context of the study (place and year), characteristics of the included population (definition of immigrants and their sub-groups), methodological domains (design of the study, source of information, statistical analysis, variables of health care use assessed, measures of need, socio-economic indicators) and main results. Results: Thirty-six publications were included, 28 from Europe and 8 from other countries. Twenty-four papers analysed the use of primary care, 17 the use of specialist services (including hospitalizations or emergency care), 18 considered several levels of care and 11 assessed mental health services. The characteristics of immigrants included country of origin, legal status, reasons for migration, length of stay, different generations and socio-demographic variables and need. In general, use of health services by the immigrants was less than or equal to the native population, although some differences between immigrants were also identified. Conclusions: This review has identified that immigrants show a general tendency towards a lower use of health services than native populations and that there are significant differences within immigrant sub-groups in terms of their patterns of utilization. Further studies should include information categorizing and evaluating the diversity within the immigrant population. PMID- 29450071 TI - Solving the global climate crisis: the greatest health opportunity of our times? AB - Today's substantial global health gains are being undermined by the threat of climate change. Ironically, the actions required to confront the climate crisis represent possibly the largest public health opportunity in more than a century. Health benefits from improved air quality may far outweigh the cost of clean energy investments. Upward trends in chronic diseases are now occurring throughout the world. Herein lies even more golden opportunities for public health through the following: first, adopting more alternative modes of transportation, especially those that promote "active transport" by foot or by bicycle, in combination with effective public transportation; and second, by reducing meat in the diet. In essence, there is no better time to focus on health as central in the climate negotiations; and in so doing, may we move faster and further with effective actions on climate change and the subsequent health benefits that will arise from a low-carbon society. PMID- 29450073 TI - The role of foundations: Rockefeller Foundation. AB - The consequences of climate change and the impacts of human activity on the environment have made it clearer than ever before that we must evolve our current model of public health to better account for the inextricable link between human health and the natural systems on which it depends-creating a "public health 2.0" that builds on the innovations of the twentieth century to account for a world where humans have bypassed planetary boundaries to achieve well-being. First coined at the Rockefeller Foundation's Centennial gathering in Beijing in 2013, "Planetary Health" will factor in future health and environmental harms over present-day gains, particularly those that disproportionately affect the poor and those in developing nations. To build this new field, foundations must address the challenge of information, increasing support for research to bridge knowledge gaps on the links between economic development, natural systems, and human health. PMID- 29450074 TI - Barriers and facilitators to extended working lives in Europe: a gender focus. AB - Background: There is a global imperative to respond to the challenge of a growing 'old-age dependency ratio' by ensuring the workforce is healthy enough to remain in work for longer. Currently more than half of older workers leave before the default retirement age, and in some countries (e.g. the UK), the time spent in retirement is increasing. At the same time across Europe, there is a gender employment gap, with 14.5% fewer female workers between 55-64 years old, and a large variation in the participation of older women in the workforce (ranging from 30-75%). As older women are under-represented in the workforce, increasing employment in this group has the propensity to go some way towards reducing the old-age dependency ratio to ensure continued economic growth. Objectives: This review explores the barriers and facilitators to extended working lives in Europe, particularly those that impact on women. Methods: A systematic mapping review process was undertaken using four electronic databases, MEDLINE, PsychoINFO, PsychEXTRA via Ovid and AgeLine via EBSCO, using the terms, 'work', 'ageing', 'retirement', 'pension', 'old', 'barrier', 'extended working life', 'gender' and 'health and well-being'. Hand searching was also carried out in the International Journal of Aging and Human Development and the International Journal of Aging and Society. Results: The search resulted in 15 English language studies published from 1st January 2005 to the current date that met the inclusion criteria. Key findings: The key factors that influenced decisions to retire or extend working lives in Europe were health, social factors, workplace factors, and financial security and pension arrangements. Conclusions and implications of the key findings: Health was found to be the most commonly cited barrier to extended working lives in Europe, and a number of social inequalities to work exist by gender. Structural factors exist, such as the gender pay gap, which disadvantages women, while the nature of work itself differs by gender and can have a negative impact on health. Currently, women tend to exit the labour market earlier than men; however, changes in the state pension age are resulting in women being required to work for as long as men, in most countries. For women to remain healthy at work, workplaces need to consider a range of interventions, including flexible arrangements to both work and retirement to enable women to balance the demands of work with domestic and caring responsibilities that particularly impact on them. PMID- 29450075 TI - Positive postpartum depression screening practices and subsequent mental health treatment for low-income women in Western countries: a systematic literature review. AB - Problem statement and significance: Left undiagnosed and/or untreated, the short and long-term sequelae of postpartum depression may negatively impact both mother and child. In Western countries, access to mental health care is influenced by socioeconomic factors. The objective of this systematic literature review is to compile factors that hinder and improve access to postpartum depression treatment in low-income women after a positive screen for postpartum depression. The key question of focus is: what are the characteristics associated with access to mental health treatment for low-income women with a positive postpartum depression screen in Western countries? Methods: A PRISMA-based systematic literature review was conducted of studies published in English before February 2016 that looked at treatment for postpartum depression in low-income women who had been identified with the condition. PubMed and EBSCO databases were searched using MESH and key terms and found 100 articles that met the selection criteria. After review by two independent researchers, 18 studies with 17 unique populations were included in the literature review. Results: Two independent abstractors searched the included articles for themes surrounding impediments and advantages for low-income women identified with postpartum depression in obtaining mental health treatment. Characteristics of successful mental health treatment included studies that employed the use of a home visitor and those that separated outcomes for women with previous mental health treatment. Themes that emerged as treatment obstacles included cultural barriers, physical barriers, systemic health care barriers, and social barriers. Implications for practice: This review will help to better inform screening and treatment priorities for those in the medical field who may encounter women experiencing postpartum depression and are not aware of the various barriers to care specific to low income women. This review will also help policymakers identify specific obstacles that are not addressed in postpartum screening mandate policies which can affect the implementation of these policies. PMID- 29450072 TI - Hispanic health in the USA: a scoping review of the literature. AB - Hispanics are the largest minority group in the USA. They contribute to the economy, cultural diversity, and health of the nation. Assessing their health status and health needs is key to inform health policy formulation and program implementation. To this end, we conducted a scoping review of the literature and national statistics on Hispanic health in the USA using a modified social ecological framework that includes social determinants of health, health disparities, risk factors, and health services, as they shape the leading causes of morbidity and mortality. These social, environmental, and biological forces have modified the epidemiologic profile of Hispanics in the USA, with cancer being the leading cause of mortality, followed by cardiovascular diseases and unintentional injuries. Implementation of the Affordable Care Act has resulted in improved access to health services for Hispanics, but challenges remain due to limited cultural sensitivity, health literacy, and a shortage of Hispanic health care providers. Acculturation barriers and underinsured or uninsured status remain as major obstacles to health care access. Advantageous health outcomes from the "Hispanic Mortality Paradox" and the "Latina Birth Outcomes Paradox" persist, but health gains may be offset in the future by increasing rates of obesity and diabetes. Recommendations focus on the adoption of the Health in All Policies framework, expanding access to health care, developing cultural sensitivity in the health care workforce, and generating and disseminating research findings on Hispanic health. PMID- 29450076 TI - An examination of the growing US undergraduate public health movement. AB - Objectives: With over 10,900 public health bachelor's degree graduates conferred in 2015, public health undergraduate education in the USA has become mainstream. However, with the recent establishment of a majority of the programs, the impact of the undergraduate programs remains largely unknown. This study examines a sample of undergraduate programs in public health to further elucidate the undergraduate landscape. Methods: Semi-structured interviews and a review of program websites from a sample of 39 institutions across the USA with undergraduate majors labeled as public health were conducted in 2015 to examine program content and operations. Results: Findings from the 39 programs reviewed demonstrated growing and diverse undergraduate public health programs rapidly evolving. While program enrollments, infrastructure, and curriculum varied among the individual programs, collectively, findings indicated increasing numbers of undergraduate students gaining knowledge and experience in matters related to the health of societies locally, nationally, and globally. Conclusions: Study findings suggest it is an opportune time for the field to offer guidance, support, and vision to these burgeoning undergraduate programs. Such engagement offers opportunities to advance the programs as well as increase the number of students attuned to societal health in whatever life roles they assume. PMID- 29450077 TI - Master of Public Health programmes in South Africa: issues and challenges. AB - Background: The demand for highly skilled public health personnel in low- and middle-income countries has been recognised globally. In South Africa, the need to train more public health professionals has been acknowledged. The Human Resource for Health (HRH) Strategy for South Africa includes the establishment of public health units at district and provincial levels. Programmes such as Master of Public Health (MPH) programmes are viewed as essential contributors in equipping health practitioners with adequate public health skills to meet the demands of the health care system. All MPH programmes have been instituted independently; there is no systematic information or comparison of programmes and requirements across institutions. This study aims to establish a baseline on MPH programmes in South Africa in terms of programme characteristics, curriculum, teaching workforce and graduate output. Methods: A mixed method design was implemented. A document analysis and cross-sectional descriptive survey, comprising both quantitative and qualitative data collection, by means of questionnaires, of all MPH programmes active in 2014 was conducted. The MPH programme coordinators of the 10 active programmes were invited to participate in the study via email. Numeric data were summarized in frequency distribution tables. Non-numeric data was captured, collated into one file and thematically analysed. Results: A total of eight MPH programmes responded to the questionnaire. Most programmes are affiliated to medical schools and provide a wide range of specialisations. The MPH programmes are run by individual universities and tend to have their own quality assurance, validation and assessment procedures with minimal external scrutiny. National core competencies for MPH programmes have not been determined. All programmes are battling to provide an appropriate supply of well-trained public health professionals as a result of drop-out, low throughput and delayed time to completion. Conclusion: The MPH programmes have consistently graduated MPH candidates, although the numbers differ by institution. The increasing number of enrolments coupled by insufficient teaching personnel and low graduate output are key challenges impacting on the production of public health professionals. Collaboration amongst the MPH programmes, standardization, quality assurance and benchmarking needs considerable attention. PMID- 29450078 TI - Polio immunization in Pakistan: ethical issues and challenges. AB - Background: Immunization should be considered a basic human right to health and well-being. It is everybody's business, and it is everybody's responsibility: the individual, the community, the health system and the state. This paper attempts to review some of the literature that highlights the ethical and religious concerns surrounding polio vaccination and what approaches may be used to counter the problems faced in Pakistan. Methods: This paper is developed through a literature review on public health and polio in Pakistan, consulting local, regional and globally published peer reviewed articles focussing on religion, culture, ethics and public health. Discussion: Human behaviour, including the utilization and acceptability of healthcare services, is greatly influenced by religious beliefs and dogmas. Immunization, specifically for the purpose of polio eradication, has been a topic under focus and in the news in Pakistan. The government is doing its best through a variety of interventions to increase access, inform the public and increase vaccination rates. Nevertheless, the country still faces a huge challenge from certain stern pockets of uncompromising populations who resist and refuse vaccination. Beliefs, practices and cultural norms overshadow public health priorities and ethics. Understanding of the context, therefore, is critical to determine the social hindrances in polio eradication and strategize thereon. Conclusion: Having programmatic, system-wide, socio-cultural and of course ethical dimensions, the policy makers and the programme managers in Pakistan must attempt to address the multitude of challenges to polio vaccination, whereby the plan of action developed within the ethical norms could potentially lead to an ultimate success. PMID- 29450079 TI - Communicating climate change and health in the media. AB - The translation of science from research to real-world change is a central goal of public health. Communication has an essential role to play in provoking a response to climate change. It must first raise awareness, make people feel involved and ultimately motivate them to take action. The goal of this research is to understand how the information related to this issue is being addressed and disseminated to different audiences-public citizens, politicians and key climate change stakeholders. Initial results show that the scientific voice struggles to globally highlight this issue to a general audience and that messages that address the topic do not meet the challenges, going from a dramatic framing to a basic adaptation framing. Communication experts can help inform scientists and policy makers on how to best share information about climate change in an engaging and motivating way. This study gives an insight about the key role of the media and communications in addressing themes relating to climate change and transmitting information to the public in order to take action.

AB - There exists a profound disconnect and misunderstanding of the utility of human rights in the practice of medicine that demands urgent attention. The United Nations Special Rapporteur, Dainius Puras, reflects on his career as a medical professional and why human rights in the day to day care of his patients became a powerful tool to strengthen his practice and ensure the dignity and well-being of those he served. This preface reflects on some of the troubling paradoxes encountered in the practice of medicine, identifying the disconnect between human rights and the provision of patient care as a fundamental struggle that urgently requires a framework for action, much like what is offered by the authors of this special edition. A historical reflection of the power relations between the medical profession and those it serves concludes with a message of hope and a galvanizing call for leadership from within the medical community to lead rights based reform in patient care. PMID- 29450080 TI - Residential schools and the effects on Indigenous health and well-being in Canada a scoping review. AB - Background: The history of residential schools has been identified as having long lasting and intergenerational effects on the physical and mental well-being of Indigenous populations in Canada. Our objective was to identify the extent and range of research on residential school attendance on specific health outcomes and the populations affected. Methods: A scoping review of the empirical peer reviewed literature was conducted, following the methodological framework of Arksey and O'Malley (2005). For this review, nine databases were used: Bibliography of Native North Americans, Canadian Health Research Collection, CINAHL, Google Scholar, Indigenous Studies Portal, PubMed, Scopus, Statistics Canada, and Web of Science. Citations that did not focus on health and residential school among a Canadian Indigenous population were excluded. Papers were coded using the following categories: Indigenous identity group, geography, age-sex, residential school attendance, and health status. Results: Sixty-one articles were selected for inclusion in the review. Most focused on the impacts of residential schooling among First Nations, but some included Metis and Inuit. Physical health outcomes linked to residential schooling included poorer general and self-rated health, increased rates of chronic and infectious diseases. Effects on mental and emotional well-being included mental distress, depression, addictive behaviours and substance mis-use, stress, and suicidal behaviours. Conclusion: The empirical literature can be seen as further documenting the negative health effects of residential schooling, both among former residential school attendees and subsequent generations. Future empirical research should focus on developing a clearer understanding of the aetiology of these effects, and particularly on identifying the characteristics that lead people and communities to be resilient to them. PMID- 29450082 TI - A human rights approach to the health implications of food and nutrition insecurity. AB - Food and nutrition insecurity continues to pose a serious global challenge, reflecting government shortcomings in meeting international obligations to ensure the availability, accessibility, and quality of food and to ensure the highest attainable standard of health of their peoples. With global drivers like climate change, urbanization, greater armed conflict, and the globalization of unhealthy diet, particularly in under-resourced countries, food insecurity is rapidly becoming an even greater challenge for those living in poverty. International human rights law can serve a critical role in guiding governments that are struggling to protect the health of their populations, particularly among the most susceptible groups, in responding to food and nutrition insecurity. This article explores and advocates for a human rights approach to food and nutrition security, specifically identifying legal mechanisms to "domesticate" relevant international human rights standards through national policy. Recognizing nutrition security as a determinant of public health, this article recognizes the important links between the four main elements of food security (i.e., availability, stability, utilization, and access) and the normative attributes of the right to health and the right to food (i.e., availability, accessibility, affordability, and quality). In drawing from the evolution of international human rights instruments, official documents issued by international human rights treaty bodies, as well as past scholarship at the intersection of the right to health and right to food, this article interprets and articulates the intersectional rights-based obligations of national governments in the face of food and nutrition insecurity. PMID- 29450083 TI - Establishing undergraduate public health education: process, challenges, and achievements in a case study in Israel. AB - Background: In this paper, we describe the development process of the first undergraduate public health baccalaureate program, in the Ashkelon Academic College in Israel. Expansion of degree-granting colleges in Israel is part of the democratization of higher education providing access to and increasing educational opportunities for groups underrepresented in universities. The main objectives of the program at Ashkelon Academic College have been to open accessible and affordable career opportunities for current workers in the health system and for new entries to health careers for academic advancement in a peripheral and relatively poor region of the country. Case Presentation: The program focuses on well-established and literature-based learning goals of public health education but also includes basic medical sciences, incorporation of arts and sciences into public health, development of critical thinking and quantitative skills, experiential field learning, and integrative learning for facing global health challenges. The curricula of the program is composed of seven modules including introductory courses, methodology courses, health organization courses, epidemiology courses, courses related to core content of public health, elective courses and practicum. The first class will graduate in 2017; this will allow for final approval of the Council of Higher Education of Israel and possible revision of curriculum. A second BA program is now seeking approval in Israel and cooperation with post-graduate schools of public health is developing. Conclusion s : Our program is in keeping with trends in Europe and the USA to broaden public health education, to reduce inequality of career opportunity, to expand the workforce, and to promote public health.

In accordance with its mission, the March of Dimes Foundation is dedicated to reducing the toll of birth defects on children, families, and society. Founded in 1938 to fight polio, March of Dimes currently focuses on prevention of birth defects and preterm birth and has had a major influence on surveillance, research, advocacy, awareness, and education related to birth defects prevention and care. In the USA, it has played an active role in promoting and advocating for newborn screening for early diagnosis and treatment of congenital disorders, folic acid fortification of grains for prevention of neural tube defects, and more recently on raising awareness about birth defects related to Zika virus infection. March of Dimes has played a major role in promoting prevention of birth defects globally by publishing data-based reports and papers related to the toll of birth defects and by supporting surveillance and preconception health education programs. March of Dimes birth defects health education materials directed for raising awareness among families are used worldwide. Additionally, March of Dimes had equipped health care workers and policy makers with essential information about birth defects through published materials and sponsoring of conferences that allow for networking and knowledge exchange. March of Dimes remains committed to prevention of birth defects through supporting research related to causes of birth defects, empowering women and girls with health knowledge, and advocating for policies and programs at national and global levels for giving every child an opportunity to attain his or her optimal level of health. PMID- 29450085 TI - Structural adjustment programmes adversely affect vulnerable populations: a systematic-narrative review of their effect on child and maternal health. AB - Structural adjustment programmes of international financial institutions have typically set the fiscal parameters within which health policies operate in developing countries. Yet, we currently lack a systematic understanding of the ways in which these programmes impact upon child and maternal health. The present article systematically reviews observational and quasi-experimental articles published from 2000 onward in electronic databases (PubMed/Medline, Web of Science, Cochrane Library and Google Scholar) and grey literature from websites of key organisations (IMF, World Bank and African Development Bank). Studies were considered eligible if they empirically assessed the aggregate effect of structural adjustment programmes on child or maternal health in developing countries. Of 1961 items yielded through database searches, reference lists and organisations' websites, 13 met the inclusion criteria. Our review finds that structural adjustment programmes have a detrimental impact on child and maternal health. In particular, these programmes undermine access to quality and affordable healthcare and adversely impact upon social determinants of health, such as income and food availability. The evidence suggests that a fundamental rethinking is required by international financial institutions if developing countries are to achieve the Sustainable Development Goals on child and maternal health. PMID- 29450086 TI - Human rights education in patient care. AB - This article explores how human rights education in the health professions can build knowledge, change culture, and empower advocacy. Through a study of educational initiatives in the field, the article analyzes different methods by which health professionals come to see the relevance of human rights norms for their work, to habituate these norms in everyday practice, and to espouse these norms in advocacy for social justice. The article seeks to show the transformative potential of education for human rights in patient care. PMID- 29450087 TI - Forced sterilization of women as discrimination. AB - There has been a long history of subjecting marginalized women to forced and coerced sterilization. In recent years, the practice has been documented in countries in North and South America, Europe, Asia, and Africa. It has targeted women who are ethnic and racial minorities, women with disabilities, women living with HIV, and poor women. A handful of courts have issued decisions on the recent forced sterilization of marginalized women finding that such actions violate the women's rights. However, they have all failed to address the women's claims of discrimination. The failure to acknowledge that forced sterilization is at its core a violation of the prohibition of discrimination undermines efforts to eradicate the practice. It further fails to recognize that coerced and forced sterilization fundamentally seeks to deny women deemed as "unworthy" the ability to procreate. Four key principles outlined in the human rights in patient care framework highlight the importance of a finding that the prohibition of discrimination was violated in cases of forced sterilization: the need to highlight the vulnerability of marginalized populations to discrimination in health care settings; the importance of the rights of medical providers; the role of the state in addressing systemic human rights violations in health care settings; and the application of human rights to patient care. Based on these principles, it is clear that finding a violation of the prohibition of discrimination in forced sterilization cases is critical in addressing the systemic nature of the practice, acknowledging the marginalization of specific groups and effectively ending forced sterilization through addressing the underlying purpose of the practice. If litigators, non-governmental organizations and judicial officers are mindful of these principles when dealing with cases of forced sterilization, it is likely that they will be better able to eradicate forced sterilization. PMID- 29450089 TI - The State's obligation to regulate and monitor private health care facilities: the Alyne da Silva Pimentel and the Dzebniauri cases. AB - The Human Rights in Patient Care framework embraces general human rights principles applicable to both patients and health care providers in the delivery of health care. Under this framework, states have a duty to ensure patient and provider rights in both public and private health care settings. The paper examines the recent decisions in Alyne Da Silva Pimentel v. Brazil of the Committee on the Elimination of Discrimination against Women and Dzebniauri v. Georgia of the European Court of Human Rights and places these decisions within the wider debate on the extent to which states have human rights obligations in private settings. Drawing on these decisions, the paper demonstrates that this duty can be complied with by establishing appropriate laws and regulations for private entities, monitoring and enforcement of the standards, and performance of these bodies and professionals through investigation and accountability procedures.

AB - Roma in Macedonia suffer from dire health consequences due to economic factors, such as high rates of unemployment and poverty, and social factors, including discrimination by medical providers. Although Macedonia administers a public health care system for its citizens, Roma frequently lack access to this system in contravention of the rights to health and equality enshrined in Macedonia's Constitution and international law. Applying a human rights in patient care (HRPC) framework to this problem, we discuss a facially neutral law that predicated access to health insurance for low-income citizens on the submission of a statement of income. This requirement created additional barriers to care, which we describe in this article. Even after the Constitutional Court declared the requirement invalid, the government failed to implement appropriate changes to the law in a timely manner. We argue this failure threatened the rule of law in the country and further marginalized and discriminated against Roma in violation of their human rights. PMID- 29450090 TI - Palliative care and human rights in patient care: an Armenia case study. AB - This paper examines palliative care within the human rights in patient care framework, which clarifies state obligations and addresses the rights of both patients and providers. In the context of palliative care, these rights extend beyond the right to health and include patient rights to freedom from torture, cruel and inhuman treatment, non-discrimination and equality, bodily integrity, privacy and confidentiality, information, and right to a remedy. They also encompass provider rights to decent working conditions, freedom of association, and due process. The paper then looks at a case study of Armenia, acknowledging how the government's commitment to palliative care, combined with awareness raising and advocacy by human rights organizations, created an enabling environment for the realization of human rights in patient care in the context of palliative care. PMID- 29450091 TI - The importance of vitamin D in maternal and child health: a global perspective. AB - Vitamin D and calcium are important nutrients for skeletal growth and bone health. Children and pregnant women are particularly vulnerable to 25-hydroxy vitamin D deficiency (VDD). VDD, with or without dietary calcium deficiency, can lead to nutritional rickets (NR), osteomalacia, and disturbances in calcium homeostasis. Multiple studies have linked VDD to adverse health outcomes in both children and pregnant women that extend beyond bone health. VDD remains an important global public health concern, and an important differentiation must be made between the impact of VDD on children and adults. Reports of increased incidence of NR continue to emerge. NR is an entirely preventable condition, which could be eradicated in infants and children worldwide with adequate vitamin D and calcium supplementation. The desire and necessity to put in place systems for preventing this potentially devastating pediatric disease should not elicit dispute. VDD and NR are global public health issues that require a collaborative, multi-level approach for the implementation of feasible preventative strategies. This review highlights the history, risk factors, and controversies related to VDD during pregnancy and childhood with a particular focus on global NR prevention. PMID- 29450092 TI - Screening for risky behaviour and mental health in young people: the YouthCHAT programme. AB - Background: The prevalence of mental health concerns and risky health behaviours among young people is of global concern. A large proportion of young people in New Zealand (NZ) are affected by depression, suicidal ideation and other mental health concerns, but the majority do not access help. For NZ indigenous Maori, the burden of morbidity and mortality associated with mental health is considerably higher. Targeted screening for risky behaviours and mental health concerns among youth in primary care settings can lead to early detection and intervention for emerging or current mental health and psychosocial issues. Opportunistic screening for youth in primary care settings is not routinely undertaken due to competing time demands, lack of context-specific screening tools and insufficient knowledge about suitable interventions. Strategies are required to improve screening that are acceptable and appropriate for the primary care environment. This article outlines the development, utilisation and ongoing evaluation and implementation strategies for YouthCHAT. YouthCHAT: YouthCHAT is a rapid, electronic, self-report screening tool that assesses risky health-related behaviours and mental health concerns, with a 'help question' that enables youth to prioritise areas they want help with. The young person can complete YouthCHAT in the waiting room prior to consultation, and after completion, the clinician can immediately access a summary report which includes algorithms for stepped care interventions using a strength-based approach. A project to scale up the implementation is about to commence, using a co-design participatory research approach to assess acceptability and feasibility with successive roll-out to clinics. In addition, a counter-balanced randomised trial of YouthCHAT versus clinician-administered assessment is underway at a NZ high school. Conclusion: Opportunistic screening for mental health concerns and other risky health behaviours during adolescence can yield significant health gains and prevent unnecessary morbidity and mortality. The systematic approaches to screening and provision of algorithms for stepped-care intervention will assist in delivering time efficient, early, more comprehensive interventions for youth with mental health concerns and other health compromising behaviours. The early detection of concerns and facilitation to evidence-based interventions has the potential to lead to improved health outcomes, particularly for under-served indigenous populations. PMID- 29450093 TI - Paid parental leave and family wellbeing in the sustainable development era. AB - Background: The Sustainable development goals (SDGs) have the potential to have a significant impact on maternal and child health through their commitments both to directly addressing health services and to improving factors that form the foundation of social determinants of health. To achieve change at scale, national laws and policies have a critical role to play in implementing the SDGs' commitments. One particular policy that could advance a range of SDGs and importantly improve maternal and infant health is paid parental leave. Methods: This article analyzes literature on paid leave and related policies relevant to SDG 1 (poverty), SDG 3 (health), SDG 5 (gender equality), SDG 8 (decent work), and SDG 10 (inequality). In addition, this article presents global data on the prevalence of policies in all 193 UN Member States. Results: A review of the literature finds that paid parental leave may support improvements across a range of SDG outcomes relevant to maternal and child health. Across national income levels, paid leave has been associated with lower infant mortality and higher rates of immunizations. In high-income countries, studies have found that paid leave increases exclusive breastfeeding and may improve women's economic outcomes. However, factors including the duration of leave, the wage replacement rate, and whether leave is made available to both parents importantly shape the impacts of paid leave policies. While most countries now offer at least some paid maternal leave, many provide less than the 6 months recommended for exclusive breastfeeding, and only around half as many provide paternal leave. Conclusions: To accelerate progress on the SDGs' commitments to maternal and child health, we should monitor countries' actions on enacting or strengthening paid leave policies. Further research is needed on the duration, wage replacement rate, and availability of leave before and after birth that would best support both child and parental health outcomes and social determinants of health more broadly. In addition, further work is needed to understand the extent to which paid leave policies extend to the informal economy, where the majority of women and men in low- and middle-income countries work. PMID- 29450095 TI - Strengthening health systems in Africa: a case study of the Kenya field epidemiology training program for local frontline health workers. AB - The logistical and operational challenges to improve public health practice capacity across Africa are well documented. This report describes Kenya's Field Epidemiology and Laboratory Training Program's (KFELTP) experience in implementing frontline public health worker training to transfer knowledge and practical skills that help strengthen their abilities to detect, document, respond to, and report unusual health events. Between May 2014 and May 2015, KFELTP hosted five training courses across the country to address practice gaps among local public health workers. Participants completed a 10-week process: two 1-week didactic courses, a 7-week field project, and a final 1-week course to present and defend the findings of their field project. The first year was a pilot period to determine whether the program could fit into the existing 2-year KFELTP model and whether this frontline-level training would have an impact on local practice. At the end of the first year, KFELTP certified 167 frontline health workers in field epidemiology and data management. This paper concludes that local, national, and international partnerships are critical for improving local public health response capacity and workforce development training in an African setting. PMID- 29450094 TI - Review of infectious diseases in refugees and asylum seekers-current status and going forward. AB - An unprecedented rise in the number of asylum seekers and refugees was seen in Europe in 2015, and it seems that numbers are not going to be reduced considerably in 2016. Several studies have tried to estimate risk of infectious diseases associated with migration but only very rarely these studies make a distinction on reason for migration. In these studies, workers, students, and refugees who have moved to a foreign country are all taken to have the same disease epidemiology. A common disease epidemiology across very different migrant groups is unlikely, so in this review of infectious diseases in asylum seekers and refugees, we describe infectious disease prevalence in various types of migrants. We identified 51 studies eligible for inclusion. The highest infectious disease prevalence in refugee and asylum seeker populations have been reported for latent tuberculosis (9-45%), active tuberculosis (up to 11%), and hepatitis B (up to 12%). The same population had low prevalence of malaria (7%) and hepatitis C (up to 5%). There have been recent case reports from European countries of cutaneous diphtheria, louse-born relapsing fever, and shigella in the asylum seeking and refugee population. The increased risk that refugees and asylum seekers have for infection with specific diseases can largely be attributed to poor living conditions during and after migration. Even though we see high transmission in the refugee populations, there is very little risk of spread to the autochthonous population. These findings support the efforts towards creating a common European standard for the health reception and reporting of asylum seekers and refugees. PMID- 29450096 TI - Post-graduate medical education in public health: the case of Italy and a call for action. AB - Public health technical expertise is of crucial importance to inform decision makers' action in the field of health and its broader determinants. Improving education and training of public health professionals for both practice and research is the starting point to strengthen the role of public health so that current health challenges can be efficiently tackled. At the Association of Schools of Public Health in the European Region (ASPHER) Deans' & Directors' 2017 Annual Retreat, we presented the structure and management of public health training system in Italy, and we reported recent data on Italian public health specialists' educational experience, employment opportunities and job satisfaction. Public health training in Italy is implemented in the context of the post-graduate medical education residency programme in Hygiene and Preventive Medicine, delivered by 34 University-based Schools of Public Health. We report relatively high employment rates across the county and wide spectrum of career opportunities for young public health specialists. However, job security is low and training expectations only partially met. We call upon other Schools of Public Health to scale up the survey within the broad ASPHER community in a shared and coordinated action of systematically collecting useful data that can inform the development of public health education and training models, their implementation and fruitful interaction with population health, health systems and services. PMID- 29450097 TI - Documenting legal status: a systematic review of measurement of undocumented status in health research. AB - Background: Undocumented status is rarely measured in health research, yet it influences the lives and well-being of immigrants. The growing body of research on undocumented status and health shows the need to assess the measurement of this legal status. We discuss the definition of undocumented status, conduct a systematic review of the methodological approaches currently taken to measure undocumented status of immigrants in the USA, and discuss recommendations for advancement of measurement methods. Methods: We conducted a systematic review of 61 studies indexed in PubMed, conducted in the USA, and published from 2004 to 2014. We categorized each of the studies' data source and type, measurement type, and information for classifying undocumented participants. Studies used self reported or proxy measures of legal status. Results: Information to classify undocumented participants included self-reported status, possession of a Social Security number, possession of health insurance or institutional resources, concern about deportation, and participant characteristics. Findings show it is feasible to collect self-reported measures of undocumented status. Conclusions: We recommend that researchers collect self-reported measures of undocumented status whenever possible and limit the use of proxy measures. Validated and standardized measures are needed for within and across country measurement. Authors should provide methodological information about measurement in publications. Finally, individuals who are undocumented should be included in the development of these methodologies. Trial registration: This systematic review is not registered. PMID- 29450098 TI - International financial institutions and human rights: implications for public health. AB - Serving as lender of last resort to countries experiencing unsustainable levels of public debt, international financial institutions have attracted intense controversy over the past decades, exemplified most recently by the popular discontent expressed in Eurozone countries following several rounds of austerity measures. In exchange for access to financial assistance, borrowing countries must settle on a list of often painful policy reforms that are aimed at balancing the budget. This practice has afforded international financial institutions substantial policy influence on governments throughout the world and in a wide array of policy areas of direct bearing on human rights. This article reviews the consequences of policy reforms mandated by international financial institutions on the enjoyment of human rights, focusing on the International Monetary Fund and World Bank. It finds that these reforms undermine the enjoyment of health rights, labour rights, and civil and political rights, all of which have deleterious implications for public health. The evidence suggests that for human rights commitments to be met, a fundamental reorientation of international financial institutions' activities will be necessary. PMID- 29450100 TI - Human rights in patient care and public health-a common ground. AB - Medical law and public health law have both served extensively as instruments of health protection and promotion-yet both are limited in their effect and scope and do not sufficiently cover nor supply a remedy to systematic, rather than anecdotal, mistreatments in the health care system. A possible solution to this deficiency may be found in the human rights in patient care legal approach. The concept of human rights in patient care is a reframing of international human rights law, as well as constitutional thought and tools, into a coherent approach aimed at the protection and furthering of both personal and communal health. It applies human rights discourse and human rights law onto the patient care setting while moving away from the narrow consumeristic view of health care delivery. By applying human rights in patient care approach, both national and international courts may and should serve as policy influencing instruments, protecting the rights of the most vulnerable and prejudiced against groups, which are want of a remedy through traditional patients' rights legal schemes. PMID- 29450099 TI - The impact of programs for prevention of mother-to-child transmission of HIV on health care services and systems in sub-Saharan Africa - A review. AB - Background: The global scale-up of Prevention of mother-to-child transmission (PMTCT) services is credited for a 52% worldwide decline in new HIV infections among children between 2001 and 2012. However, the epidemic continues to challenge maternal and paediatric HIV control efforts in Sub Saharan Africa (SSA), with repercussions on other health services beyond those directly addressing HIV and AIDS. This systematised narrative review describes the effects of PMTCT programs on other health care services and the implications for improving health systems in SSA as reported in the existing articles and scientific literature. The following objectives framed our review:To describe the effects of PMTCT on health care services and systems in SSA and assess whether the PMTCT has strengthened or weakened health systems in SSATo describe the integration of PMTCT and its extent within broader programs and health systems. Methods: Articles published in English and French over the period 1st January 2007 (the year of publication of WHO/UNICEF guidelines on global scale-up of the PMTCT) to 31 November 2016 on PMTCT programs in SSA were sought through searches of electronic databases (Medline and Google Scholar). Articles describing the impact (positive and negative effects) of PMTCT on other health care services and those describing its integration in health systems in SSA were eligible for inclusion. We assessed 6223 potential papers, reviewed 225, and included 57. Results: The majority of selected articles offered arguments for increased health services utilisation, notably of ante-natal care, and some evidence of beneficial synergies between PMTCT programs and other health services especially maternal health care, STI prevention and early childhood immunisation. Positive and negative impact of PMTCT on other health care services and health systems are suggested in thirty-two studies while twenty-five papers recommend more integration and synergies. However, the empirical evidence of impact of PMTCT integration on broader health systems is scarce. Underlying health system challenges such as weak physical and human resource infrastructure and poor working conditions, as well as social and economic barriers to accessing health services, affect both PMTCT and the health services with which PMTCT interacts. Conclusions: PMTCT services increase to some extent the availability, accessibility and utilisation of antenatal care and services beyond HIV care. Vertical PMTCT programs work, when well-funded and well-managed, despite poorly functioning health systems. The beneficial synergies between PMTCT and other services are widely suggested, but there is a lack of large-scale evidence of this. PMID- 29450101 TI - Implementing SBIRT (Screening, Brief Intervention and Referral to Treatment) in primary care: lessons learned from a multi-practice evaluation portfolio. AB - Background: Screening, Brief Intervention and Referral to Treatment (SBIRT) is a public health framework approach used to identify and deliver services to those at risk for substance-use disorders, depression, and other mental health conditions. Primary care is the first entry to the healthcare system for many patients, and SBIRT offers potential to identify these patients early and assist in their treatment. There is a need for pragmatic "best practices" for implementing SBIRT in primary care offices geared toward frontline providers and office staff. Methods: Ten primary care practices were awarded small community grants to implement an SBIRT program in their location. Each practice chose the conditions for which they would screen, the screening tools, and how they would provide brief intervention and referral to treatment within their setting. An evaluation team communicated with each practice throughout the process, collecting quantitative and qualitative data regarding facilitators and barriers to SBIRT success. Using the editing method, the qualitative data were analyzed and key strategies for success are detailed for implementing SBIRT in primary care. Results: The SBIRT program practices included primary care offices, federally qualified health centers, school-based health centers, and a safety-net emergency department. Conditions screened for included alcohol abuse, drug abuse, depression, anxiety, child safety, and tobacco use. Across practices, 49,964 patients were eligible for screening and 36,394 pre-screens and 21,635 full screens were completed. From the qualitative data, eight best practices for primary care SBIRT are described: Have a practice champion; Utilize an interprofessional team; Define and communicate the details of each SBIRT step; Develop relationships with referral partners; Institute ongoing SBIRT training; Align SBIRT with the primary care office flow; Consider using a pre-screening instrument, when available; and Integrate SBIRT into the electronic health record. Conclusions and implications: SBIRT is an effective tool that can empower primary care providers to identify and treat patients with substance use and mental health problems before costly symptoms emerge. Using the pragmatic best practices we describe, primary care providers may improve their ability to successfully create, implement, and sustain SBIRT in their practices. PMID- 29450102 TI - What is known about sexual and reproductive health in Latin American and Caribbean mining contexts? A systematic scoping review. AB - Background: Latin America and the Caribbean (LAC) has experienced an unprecedented mining boom since the mid-2000s with unknown effects on sexual and reproductive health (SRH). This study takes the essential first steps of summarizing the available literature regarding SRH in mining contexts in LAC, identifying critical gaps in knowledge, and discussing main implications for future research. Methods: We conducted a scoping review with a systematic search of health literature in four databases, reference lists of selected papers, and citations in Google Scholar. Results: The systematic search yielded 592 primary references and 16 articles from LAC. The 11 papers finally selected were conducted in gold-mining contexts in Brazil, Venezuela, Guyana, Peru, and Colombia, between 1995 and 2016. Ten studies centered on measuring HIV/STD prevalence among mineworkers and other populations; few examined associated risk factors. Eight studies reported high HIV/STD prevalence in the study population. None of the studies explored broader SRH issues. Conclusions: Available research is scarce and provides limited evidence on SRH in LAC mining contexts. Critical gaps include little knowledge on (1) broader SRH impacts besides HIV/STDs, (2) SRH in settings different from gold-mining contexts in Amazon countries, (3) mechanisms shaping SRH in LAC mining contexts, and (4) effective interventions in these scenarios. Future research must consider the distinctive demographic, environmental, socioeconomic, and gender dynamics triggered by the mining economy in the analysis of the relationship between mining and SRH, particularly in a period of extractive boom.

AB - The neural tube defects anencephaly and spina bifida are two of the most common serious congenital malformations. Most cases can be prevented by consuming sufficient folic acid immediately before pregnancy and in early pregnancy. Fortification of flour with folic acid to prevent these defects has been implemented in 81 countries without public objection or indication of harm. An obstacle to the wider adoption of fortification arises from the creation of a "tolerable upper intake level" for folate (which includes natural food folate as well as synthetic folic acid), and which has been set at 1 mg/day, thereby proscribing higher folate intakes. Increasing the intake of folic acid in a population will necessarily increase the number of people with a folate intake greater than 1 mg per day, and this concern is obstructing folic acid fortification. This paper shows that the scientific basis for setting any upper limit, let alone one at 1 mg/day, is flawed. An upper intake level is therefore unnecessary and should be removed, thus allaying unjustified concerns about folic acid fortification. As a result, the full global opportunity to prevent two serious fatal or disabling disorders can and should be realized. PMID- 29450104 TI - Strengthening effective preventive services for refugee populations: toward communities of solution. AB - Refugee populations have unequal access to primary care and may not receive appropriate health screening or preventive service recommendations. They encounter numerous health care disadvantages as a consequence of low-income status, race and ethnicity, lower educational achievement, varying degrees of health literacy, and limited English proficiency. Refugees may not initially embrace the concept of preventive care, as these services may have been unavailable in their countries of origin, or may not be congruent with their beliefs on health care. Effective interventions in primary care include the appropriate use of culturally and linguistically trained interpreters for health care visits and use of evidence-based guidelines. Effective approaches for the delivery of preventive health and wellness services require community engagement and collaborations between public health and primary care. In order to provide optimal preventive and longitudinal screening services for refugees, policies and practice should be guided by unimpeded access to robust primary care systems. These systems should implement evidence-based guidelines, comprehensive health coverage, and evaluation of process and preventive care outcomes. PMID- 29450105 TI - Infection Versus Hematoma Following Surgical Treatment of Proximal Femoral Fractures in Geriatric Patients. AB - Introduction: The surgical treatment of proximal femoral fractures predominantly involves geriatric patients and is associated with high morbidity and mortality. However, analyses on postoperative infections or hematoma are rare. Methods: Patients requiring surgical revision due to infection (n = 90) or hematoma (n = 77) in the postoperative phase were identified from an electronic database of 2000 consecutive patients surgically treated for proximal femoral fractures between 2006 and 2014. Demographic and clinical data were retrieved, including information on the pathogens in patients with infection. A follow-up on morbidity and mortality was conducted via telephone for at least 2 years postsurgery. Results: The follow-up rate was 100%, and the mean age was 81.9 years. The incidence rate of infection was 4.1% (90/2000), and women were commonly affected. Staphylococcus aureus and Staphylococcus epidermidis were the most commonly detected pathogens (35.5% and 25.5%, respectively). Mixed infections were observed in 15 patients, and Methicillin-resistant Staphylococcus aureus infections were observed in only 4 patients. A total of 77 (85.6%) infections occurred within 30 days postsurgery. The implant was preserved in 76 (84.4%) patients, and resection arthroplasty was required in 14 patients. Dementia and pertrochanteric fractures were significantly more common in the infection than in the hematoma group. Although infections were associated with high mortality rates for up to 2 years postsurgery, the rates did not significantly differ from those in the hematoma control group. Conclusion: One of every 2 patients who developed an infection following the surgical treatment of a proximal femoral fracture died within 2 years postsurgery. In addition, infections were significantly associated with dementia. Avoiding postoperative infection should be a high priority in the surgical treatment of proximal femoral fractures.

AB - Reflection mode Terahertz (THz) imaging of corneal tissue water content (CTWC) is a proposed method for early, accurate detection and study of corneal diseases. Despite promising results from ex vivo and in vivo cornea studies, interpretation of the reflectivity data is confounded by the contact between corneal tissue and dielectric windows used to flatten the imaging field. Herein, we present an optical design for non-contact THz imaging of cornea. A beam scanning methodology performs angular, normal incidence sweeps of a focused beam over the corneal surface while keeping the source, detector, and patient stationary. A quasioptical analysis method is developed to analyze the theoretical resolution and imaging field intensity profile. These results are compared to the electric field distribution computed with a physical optics analysis code. Imaging experiments validate the optical theories behind the design and suggest that quasioptical methods are sufficient for designing of THz corneal imaging systems. Successful imaging operations support the feasibility of non-contact in vivo imaging. We believe that this optical system design will enable the first, clinically relevant, in vivo exploration of CTWC using THz technology.

AB - Many human diseases result from the dysregulation of the complex interactions between tens to thousands of genes. However, approaches for the transcriptional modulation of many genes simultaneously in a predictive manner are lacking. Here, through the combination of simulations, systems modelling and in vitro experiments, we provide a physical regulatory framework based on chromatin packing-density heterogeneity for modulating the genomic information space. Because transcriptional interactions are essentially chemical reactions, they depend largely on the local physical nanoenvironment. We show that the regulation of the chromatin nanoenvironment allows for the predictable modulation of global patterns in gene expression. In particular, we show that the rational modulation of chromatin density fluctuations can lead to a decrease in global transcriptional activity and intercellular transcriptional heterogeneity in cancer cells during chemotherapeutic responses to achieve near-complete cancer cell killing in vitro. Our findings represent a 'macrogenomic engineering' approach to modulating the physical structure of chromatin for whole-scale transcriptional modulation.

AB - Angiogenesis is a critical component during wound healing, and the process is sensitive to mechanical stimuli. Current in vitro culture environments used to investigate three-dimensional microvascular growth often lack dimensional stability and the ability to withstand compression. We investigated the ability of decorin, a proteoglycan known to modulate collagen fibrillogenesis, incorporated into a collagen hydrogel to increase construct dimensional stability while maintaining vascular growth. Decorin did not affect microvascular growth parameters, while increasing the compressive modulus of collagen gels and significantly reducing the contraction of 3% collagen gels after 16 days in culture. PMID- 29450109 TI - Determination of diffusion coefficients in live cells using fluorescence recovery after photobleaching with wide-field fluorescence microscopy. AB - Fluorescence recovery after photobleaching (FRAP) enables characterization of quantitative dynamic properties such as diffusion coefficients of fluorescent molecules in living cells by analyzing the recovery of fluorescence intensity after photobleaching in a specific cellular compartment or area. To quantitatively determine high intracellular diffusion coefficients, a suitable optical system as well as an appropriate model for fast diffusion analysis is necessary. Here, we propose a procedure to quantify the diffusion coefficient of rapidly-diffusing fluorescent molecules that makes use of an epi-fluorescence microscope with a photobleaching laser in combination with established models for diffusion analysis. Analysis for the diffusion coefficients of tandemly oligomerized green flurescent proteins (GFPs) in living cells when changing the photobleaching times showed that photobleaching with shorter times than the diffusion speed indicated not the only way to obtain appropriate diffusion coefficients of fast-moving molecules. Our results also showed that the apparent spreading of the effective radius of the photobleached area works as a correction factor for determining appropriate diffusion coefficients of fast-moving molecules like monomeric GFPs. Our procedure provides a useful approach for quantitative measurement of diffusion coefficients in living cells. This procedure is relevant for characterizing dynamic molecular interactions, especially of fast-moving molecules, and is relevant for studies in many biological fields. PMID- 29450110 TI - Quantitative analyses of the equilibria among DNA complexes of a blue-light regulated bZIP module, Photozipper. AB - Aureochrome1 is a blue-light-receptor protein identified in a stramenopile alga, Vaucheria frigida. Photozipper (PZ) is an N-terminally truncated, monomeric, V. frigida aureochrome1 fragment containing a basic leucine zipper (bZIP) domain and a light-oxygen-voltage (LOV)-sensing domain. PZ dimerizes upon photoexcitation and consequently increases its affinity for the target sequence. In the present study, to understand the equilibria among DNA complexes of PZ, DNA binding by PZ and mutational variants was quantitatively investigated by electrophoretic mobility-shift assay and fluorescence-correlation spectroscopy in the dark and light states. DNA binding by PZ was sequence-specific and light-dependent. The half-maximal effective concentration of PZ for binding to the target DNA sequence was ~40 nM in the light, which was >10-fold less than the value in the dark. By contrast, the dimeric PZ-S2C variant (with intermolecular disulfide bonds) had higher affinity for the target sequence, with dissociation constants of ~4 nM, irrespective of the light conditions. Substitutions of Glu159 and Lys164 in the leucine zipper region decreased the affinity of PZ for the target sequence, especially in the light, suggesting that these residues form inter-helical salt bridges between leucine zipper regions, stabilizing the dimer-DNA complex. Our quantitative analyses of the equilibria in PZ-DNA-complex formation suggest that the blue-light-induced dimerization of LOV domains and coiled-coil formation by leucine zipper regions are the primary determinants of the affinity of PZ for the target sequence. PMID- 29450111 TI - The binding structure and affinity of photodamaged duplex DNA with members of the photolyase/cryptochrome family: A computational study. AB - Photolyases (PHRs) and cryptochromes (CRYs) belong to the same family known as blue-light photoreceptors. Although their amino acid sequences and corresponding structures are similar to each other, they exert different functions. PHRs function as an enzyme to repair UV-induced deoxyribonucleic acid (DNA) lesions such as a cyclobutane pyrimidine dimer (CPD) and a (6-4) photoproduct ((6-4)pp), whereas CRYs are a circadian photoreceptor in plants and animals and at the same time they control the photoperiodic induction of flowering in plants. When a new type cryptochrome was identified, it was assumed that another type of CRYs, cryptochrome-DASH (CRY-DASH), which is categorized as a subfamily of photolyase/cryptochrome family, would possess the DNA photolyase activity. However, CRY-DASH had a weak DNA photolyase activity, but the reason for this is still unclear. To clarify the reason, we performed molecular dynamics (MD) simulations for a complex of CPD-PHR or CRY-DASH with damaged double-stranded DNA (dsDNA) and estimated the binding free energy, DeltaGbind, between the protein and the damaged dsDNA by using a molecular mechanics/Poisson-Boltzmann surface area (MM/PBSA) method. DeltaGbind for both proteins were -35 and 57 kcal mol-1, respectively, indicating that the structural stability of CRY-DASH was lower than that of CPD-PHR upon the damaged dsDNA binding. In particular, the number of amino acid residues relevant to the damaged dsDNA binding on the CRY-DASH surface was smaller than that on CPD-PHR. Therefore, the present result suggests that CRY DASH has a weak DNA photolyase activity because it has a lower binding affinity than CPD-PHR. PMID- 29450112 TI - Effect of Bacillus pumilus CCIBP-C5 on Musa-Pseudocercospora fijiensis interaction. AB - The effect of antifungal activity of culture filtrate (CF) of Bacillus pumilus strain CCIBP-C5, an isolate from a phyllosphere of banana (Musa) leaves, was determined on Pseudocercospora fijiensis challenged banana plants. The CF was shown to decrease the fungal biomass and induce changes in banana plant. In this sense, at 70 days post inoculation (dpi), a lower infection index as well as a decrease in fungal biomass after 6 dpi was obtained in treated plants with respect to control ones. At the same time, changes in the activities of several enzymes related to plant defense responses, such as phenylalanine ammonia lyase, chitinases, beta-1,3-glucanases and peroxidases were observed. These results indicate that B. pumilus CCIBP-C5 has a potential role for biological control of P. fijiensis possibly due to the production of antifungal metabolites. PMID- 29450113 TI - Potential improvement of biogas production from fallen teak leaves with co digestion of microalgae. AB - Biogas production from anaerobic co-digestion of fallen teak leaves (Tectona grandis) and microalgae (Chlorella vulgaris) were investigated. In this study, teak leaves and algae mixtures with or without pretreatment were used as the substrates and digested in 1-L of anaerobic fermenter, then optimal conditions were performed in 6-L fermenter. Pretreatment was performed using sodium hydroxide (NaOH) solution (w/v) at different conditions (0, 2, 3 and 4%), with different total solid (TS) ratios (10, 15 and 20%). The digesters were placed in an incubator at 34-36 degrees C for 45 days. The results showed that the co digestion of pretreated (10% TS with 2% NaOH) of teak leaves and algae was significantly higher in terms of biodegradability of TS, VS, COD along with biogas yield, methane potential and highest yield was achieved 71.90% than those obtained by mono-digestion. Thus, results demonstrated that anaerobic fermentation of teak leaves and microalgae in digester system could get as high methane yield. PMID- 29450114 TI - Flavonoid-rich extract of Chromolaena odorata modulate circulating GLP-1 in Wistar rats: computational evaluation of TGR5 involvement. AB - : Chromolaena odorata is a major bio-resource in folkloric treatment of diabetes. In the present study, its anti-diabetic component and underlying mechanism were investigated. A library containing 140 phytocompounds previously characterized from C. odorata was generated and docked (Autodock Vina) into homology models of dipeptidyl peptidase (DPP)-4, Takeda-G-protein-receptor-5 (TGR5), glucagon-like peptide 1 (GLP1) receptor, renal sodium dependent glucose transporter (SGLUT)-1/2 and nucleotide-binding oligomerization domain (NOD) proteins 1&2. GLP-1 gene (RT PCR) modulation and its release (EIA) by C. odorata were confirmed in vivo. From the docking result above, TGR5 was identified as a major target for two key C. odorata flavonoids (5,7-dihydroxy-6-4-dimethoxyflavanone and homoesperetin-7 rutinoside); sodium taurocholate and C. odorata powder included into the diet of the animals both raised the intestinal GLP-1 expression versus control (p < 0.05); When treated with flavonoid-rich extract of C. odorata (CoF) or malvidin, circulating GLP-1 increased by 130.7% in malvidin-treated subjects (0 vs. 45 min). CoF treatment also resulted in 128.5 and 275% increase for 10 and 30 mg/kg b.w., respectively. CONCLUSIONS: The results of this study support that C. odorata flavonoids may modulate the expression of GLP-1 and its release via TGR5. This finding may underscore its anti-diabetic potency. PMID- 29450115 TI - Plipastatin A1 produced by a marine sediment-derived Bacillus amyloliquefaciens SH-B74 contributes to the control of gray mold disease in tomato. AB - Certain Bacillus species have the capacity to produce cyclic lipopeptides and these lipopeptides are promising determinants contributing to the biocontrol of plant diseases. In the current study, a cyclic lipopeptide plipastatin A1 was isolated from the fermentation broth of a marine sediment-derived Bacillus amyloliquefaciens SH-B74 by the combination of solid-phase extraction and reversed-phase high-performance liquid chromatography, and its structure was identified by tandem mass spectrometry, high-resolution electro-spray ionization mass spectrometry, and gas chromatography-mass spectrometry together with nuclear magnetic resonance analysis. Moreover, data from activity evaluation revealed that plipastatin A1 has excellent in vitro activity on the suppression of the conidia germination of B. cinerea, the causal agent of gray mold disease in tomato. Furthermore, plipastatin A1 can successfully decrease the incidence of gray mold disease on tomato leaves at 50 uM concentration. This study indicates that B. amyloliquefaciens SH-B74 appears to be a potentially sustainable pesticide to control gray mold disease in tomato plants, and its cyclic lipopeptide plipastatin A1 plays an important role in the in vitro and in planta biocontrol of B. cinerea. PMID- 29450116 TI - The potential of the newly isolated thermotolerant Kluyveromyces marxianus for high-temperature ethanol production using sweet sorghum juice. AB - In this work, the newly isolated thermotolerant Kluyveromyces marxianus DBKKUY 103 exhibited a high ethanol fermentation efficiency at high temperatures using sweet sorghum juice (SSJ). The highest ethanol concentrations and productivities achieved under the optimum conditions using thermotolerant K. marxianus DBKKUY 103 were 85.16 g/l and 1.42 g/l.h at 37 degrees C and 83.46 g/l and 1.39 g/l.h at 40 degrees C, respectively. The expression levels of genes during ethanol fermentation at 40 degrees C were evaluated and the results found that the transcriptional levels of the RAD10, RAD14, RAD33, RAD50, ATPH, ATP4, ATP16, and ATP20 genes were up-regulated compared with those at 30 degrees C, suggesting that the high growth and high ethanol production efficiencies of K. marxianus DBKKUY-103 during high-temperature ethanol production associated with the genes involved in DNA repair and ATP production. PMID- 29450117 TI - Comparison of response surface methodology and artificial neural network to enhance the release of reducing sugars from non-edible seed cake by autoclave assisted HCl hydrolysis. AB - In the current investigation, statistical approaches were adopted to hydrolyse non-edible seed cake (NESC) of Pongamia and optimize the hydrolysis process by response surface methodology (RSM). Through the RSM approach, the optimized conditions were found to be 1.17%v/v of HCl concentration at 54.12 min for hydrolysis. Under optimized conditions, the release of reducing sugars was found to be 53.03 g/L. The RSM data were used to train the artificial neural network (ANN) and the predictive ability of both models was compared by calculating various statistical parameters. A three-layered ANN model consisting of 2:12:1 topology was developed; the response of the ANN model indicates that it is precise when compared with the RSM model. The fit of the models was expressed with the regression coefficient R2, which was found to be 0.975 and 0.888, respectively, for the ANN and RSM models. This further demonstrated that the performance of ANN was better than that of RSM. PMID- 29450118 TI - Elite hairy roots of Raphanus sativus (L.) as a source of antioxidants and flavonoids. AB - An efficient protocol for hairy root induction in radish was established by optimizing several parameters that affect the efficiency of Agrobacterium rhizogenes-mediated transformations. Explants wounded using sterile hypodermic needle, infected with Agrobacterium suspension (0.6 OD600) for 10 min and co cultivated in 1/2 MS medium containing acetosyringone (100 uM) for 2 days displayed maximum percentage of hairy root induction using MTCC 2364 (77.6%) and MTCC 532 (67.6%). On further experiments with MTCC 2364 initiated hairy roots, maximum biomass accumulation (fresh weight = 9.50 g; dry weight = 1.48 g) was achieved in liquid 1/2 MS medium supplemented with 87.6 mM sucrose after 40 days of culture. Transgenic state of hairy roots of MTCC 2364 was confirmed by polymerase chain reaction using rolB- and rolC-specific primers. The MTCC 2364 induced hairy roots produced higher amount of phenolic (33.0 mg g-1), flavonoid (48.0 mg g-1), and quercetin (114.8 mg g-1) content compared to auxin-induced roots of non-transformed radish. Furthermore, the results of ferric reducing antioxidant power and 1,1-diphenyl-2-picrylhydrazyl assay confirmed that the antioxidant activity of MTCC 2364 root extracts was improved when compared to auxin-induced roots of non-transformed radish. The present study offers a new insight in radish for production of phenolics and flavonoids (quercetin) using A. rhizogenes-mediated hairy root induction. PMID- 29450119 TI - Evidence of antidiabetic activity of Spirulina fusiformis against streptozotocin induced diabetic Wistar albino rats. AB - The aim of our study is to investigate the protective effect of Spirulina fusiformis against streptozotocin-induced diabetes in Wistar albino rats. Rats were divided into five groups: group I was normal control, group II was diabetic control (50 mg/kg b.w. of streptozotocin, i.p.), group III was Spirulina fusiformis (400 mg/kg b.w., p.o.) treated diabetic rats; group IV was Glibenclamide (0. 6 mg/kg b.w., p.o.) treated diabetic rats and group V was treated with Spirulina fusiformis (400 mg/kg b.w., p.o.) alone. There was significant elevation in the levels of blood glucose, serum lipid profile and serum renal markers (total protein, urea, creatinine and uric acid) in the diabetic rats. Also, diabetic rats showed significantly (P < 0.05) reduced antioxidant status (reduced levels of superoxide dismutase, catalase, glutathione peroxidase, glutathione-S-transferase and reduced glutathione; increased levels of TBARS), impaired oral glucose tolerance and elevated HbA1C. Spirulina fusiformis was able to normalize the above mentioned parameters. Significant histopathological changes were found in the pancreas, liver and kidney sections of the diabetic control group while treatment with Spirulina fusiformis was able to minimize the extent of tissue damage. Current study shows that Spirulina fusiformis possesses significant antidiabetic and antihyperlipidemic effects in streptozotocin-induced diabetic rats by effectively reducing the rise in blood glucose levels and lipid profile. PMID- 29450120 TI - Anaerobic digestion of sulphate-rich post-tanning wastewater at different COD/sulphate and F/M ratios. AB - Anaerobic digestion of post-tanning wastewater was performed in batch anaerobic digester to evaluate the effect of COD/sulphate ratio [0.62, 0.69, and 1.20 (w/w) %] and F/M ratio [0.2, 0.3, 0.5, 0.7, 0.9, 1.1, 1.3, and 1.5 (w/w) %)] on the removal efficiency of COD. The F/M ratio of 0.3 was found to be the optimum ratio for the removal of COD by 53, 57, and 65%, respectively at COD/sulphate ratio of 0.62, 0.69, and 1.20. The maximum sulphate removal was observed at F/M ratio of 0.2 and the removal efficiency was 48, 50, and 58% at COD/sulphate ratio of 0.62, 0.69, and 1.20, respectively. The removal efficiency of COD and sulphate was increased with increase in COD/sulphate ratio from 0.62 to 1.20 and decreased with increase in F/M ratio from 0.2 to 1.5 in anaerobic digestion of post-tanning wastewater. The maximum concentration of sulphide formation was 784 mg/L at COD/sulphate ratio of 0.62 in anaerobic digestion process and the process was inhibited at this sulphide concentration. The microbial activity in the sludge was evaluated through live and dead cell assay using fluorescent microscopy. The maximum amount of dead microbes was observed in the anaerobic digester, which was operated at COD/sulphate ratio of 0.62 than other studied ratio. PMID- 29450121 TI - Glyphosate induced toxicity to chickpea plants and stress alleviation by herbicide tolerant phosphate solubilizing Burkholderia cepacia PSBB1 carrying multifarious plant growth promoting activities. AB - In this study, strain PSBB1 isolated from Vicia faba rhizosphere was identified as Burkholderia cepacia, by 16S rDNA sequence analysis and characterized. Strain PSBB1 tolerated glyphosate up to 3200 MUg ml-1 and produced IAA (81.6 MUg ml-1), ACC deaminase (69.3 mg-1 protein h-1), SA (39.3 MUg ml-1) and 2,3-DHBA (26.6 MUg ml-1), solubilized insoluble P (50.8 MUg ml-1) and secreted 29.4 MUg ml-1 exopolysaccharides, which decreased with increasing concentrations of glyphosate. Cell damage following glyphosate application was visible under SEM and CLSM. The phytotoxicity of glyphosate on chickpea was variable but significant. B. cepacia mitigated toxicity and enhanced the size, dry matter, symbiosis, seed attributes and nutritional contents of chickpea. Further, B. cepacia strain PSBB1 declined the levels of CAT, POD, APX and GPX and MDA contents at 4332 MUg kg-1 soil glyphosate. Proline also increased under glyphosate stress but declined in B. cepacia inoculated plants. The ability to tolerate higher concentration of glyphosate, the capacity to secrete plant growth regulators even under herbicide stress and potential to reduce the level of proline and antioxidant enzymes makes B. cepacia as an interesting choice for enhancing chickpea production in soils contaminated even with herbicides. PMID- 29450122 TI - Methyl Perillate as a Highly Functionalized Natural Starting Material for Terephthalic Acid. AB - Renewable commodity chemicals can be generated from plant materials. Often abundant materials such as sugars are used for this purpose. However, these lack appropriate functionalities and, therefore, they require extensive chemical modifications before they can be used as commodity chemicals. The plant kingdom is capable of producing an almost endless variety of compounds, including compounds with highly appropriate functionalities, but these are often not available in high quantities. It has been demonstrated that it is possible to produce functionalized plant compounds on a large scale by fermentation in microorganisms. This opens up the potential to exploit plant compounds that are less abundant, but functionally resemble commodity chemicals more closely. To elaborate this concept, we demonstrate the suitability of a highly functionalized plant compound, methyl perillate, as a precursor for the commodity chemical terephthalic acid. PMID- 29450123 TI - Epidemiology and Treatment of Hepatitis B in Prisoners. AB - Purpose of Review: The review details recent literature reports regarding Hepatitis B Virus (HBV) and, in particular, Hepatitis B prevalence/incidence in incarcerated populations around the world. Furthermore, the review will summarize the national/international guidelines regarding HBV and look at diagnosis, vaccination, treatment, and linkage to care after release. Recent Findings: HBV affects prisoners at a much higher rate than the general populations. Many who are at increased risk for HBV infection are also at increased risk for incarceration. Incarcerated settings also have higher rates of HBV transmission. Summary: Incarcerated individuals should be immunized if they are not already immune to HBV. Increased access to safe injecting and tattoo paraphernalia, condoms, and personal hygiene equipment could reduce the spread of HBV and other blood-borne and sexually transmitted infections. Future research should focus on ways to prevent the spread of HBV and similar viruses in incarcerated settings in order to protect incarcerated individuals and the general public. Research on effective linkage to community HBV care following release is needed. PMID- 29450124 TI - Reflections on the Future of Epidemiology: How Students Can Inform Our Vision. PMID- 29450125 TI - Characterization of the activity of beta-galactosidase from Escherichia coli and Drosophila melanogaster in fixed and non-fixed Drosophila tissues. AB - beta-Galactosidase encoded by the Escherichia coli lacZ gene, is widely used as a reporter molecule in molecular biology in a wide variety of animals. beta Galactosidase retains its enzymatic activity in cells or tissues even after fixation and can degrade X-Gal, a frequently used colormetric substrate, producing a blue color. Therefore, it can be used for the activity staining of fixed tissues. However, the enzymatic activity of the beta-galactosidase that is ectopically expressed in the non-fixed tissues of animals has not been extensively studied. Here, we report the characterization of beta-galactosidase activity in Drosophila tissues with and without fixation in various experimental conditions comparing the activity of two evolutionarily orthologous beta galactosidases derived from the E. coli lacZ and Drosophila melanogaster DmelGal genes. We performed quantitative analysis of the activity staining of larval imaginal discs and an in vitro assay using larval lysates. Our data showed that both E. coli and Drosophila beta-galactosidase can be used for cell-type-specific activity staining, but they have their own preferences in regard to conditions. E. coli beta-galactosidase showed a preference for neutral pH but not for acidic pH compared with Drosophila beta-galactosidase. Our data suggested that both E. coli and Drosophila beta-galactosidase show enzymatic activity in the physiological conditions of living animals when they are ectopically expressed in a desired specific spatial and temporal pattern. This may enable their future application to studies of chemical biology using model animals. PMID- 29450126 TI - Structural properties of the linkers connecting the N- and C- terminal domains in the MocR bacterial transcriptional regulators. AB - Peptide inter-domain linkers are peptide segments covalently linking two adjacent domains within a protein. Linkers play a variety of structural and functional roles in naturally occurring proteins. In this work we analyze the sequence properties of the predicted linker regions of the bacterial transcriptional regulators belonging to the recently discovered MocR subfamily of the GntR regulators. Analyses were carried out on the MocR sequences taken from the phyla Actinobacteria, Firmicutes, Alpha-, Beta- and Gammaproteobacteria. The results suggest that MocR linkers display phylum-specific characteristics and unique features different from those already described for other classes of inter-domain linkers. They show an average length significantly higher: 31.8 +/- 14.3 residues reaching a maximum of about 150 residues. Compositional propensities displayed general and phylum-specific trends. Pro is dominating in all linkers. Dyad propensity analysis indicate Pro-Pro as the most frequent amino acid pair in all linkers. Physicochemical properties of the linker regions were assessed using amino acid indices relative to different features: in general, MocR linkers are flexible, hydrophilic and display propensity for beta-turn or coil conformations. Linker sequences are hypervariable: only similarities between MocR linkers from organisms related at the level of species or genus could be found with sequence searches. The results shed light on the properties of the linker regions of the new MocR subfamily of bacterial regulators and may provide knowledge-based rules for designing artificial linkers with desired properties. PMID- 29450127 TI - Mobile phones electromagnetic radiation and NAD+-dependent isocitrate dehydrogenase as a mitochondrial marker in asthenozoospermia. AB - NAD+-dependent Isocitrate Dehydrogenase (NAD+-IDH) could be one of the cell phone radiation targets. Enzyme activity alteration may lead to decline in sperm motility during radio-frequency electromagnetic waves (RF-EMW) exposure. The current case control study aimed to investigate the possible relationship between mitochondrial NAD+-IDH activity in human seminal plasma and sperm motility among asthenozoospermic cellular phone users. A total number of ninety idiopathic infertile males referred from the Department of Dermatology and Andrology, were enrolled in this study. NAD+-IDH activity was measured in human seminal plasma by spectrophotometer. Computer-aided sperm analysis (CASA) following WHO criteria has been used for semen analyses. The results showed that IDH activity was increased in patients with prolonged cell phone daily use >=4 h/day. Its level, correlated negatively with either the motility ratio percentages (r = -0.46, p < 0.001) or the progressive motility percentages (r = -0.50, p < 0.001) in the study groups. The current study suggests that NAD+-IDH in human seminal plasma could be one of seminal plasma biomarkers reflecting the mitochondrial function of spermatozoa. Alteration of its level could reflect the defective motility of sperms among some cases of cellular phone users. PMID- 29450128 TI - Molecular characterization and analysis of the porcine NURR1 gene. AB - Orphan receptor NURR1 (also termed NR4A2) belongs to the nuclear receptor superfamily and functions as a regulatory factor of differentiation, migration, maturation and maintenance of mesencephalic dopaminergic neurons. NURR1 plays an important role in nigrostriatal dopamine neuron development and is therefore implicated in the pathogenesis of neurodegenerative diseases linked to the dopamine system of the midbrain. Here we report the isolation and characterization of porcine NURR1 cDNA. The NURR1 cDNA was RT-PCR cloned using NURR1-specific oligonucleotide primers derived from in silico sequences. The porcine NURR1 cDNA encodes a polypeptide of 598 amino acids, displaying a very high similarity with bovine, human and mouse (99%) NURR1 protein. Expression analysis revealed a differential NURR1 mRNA expression in various organs and tissues. NURR1 transcripts could be detected as early as at 60 days of embryo development in different brain tissues. A significant increase in NURR1 transcript in the cerebellum and a decrease in NURR1 transcript in the basal ganglia was observed during embryo development. The porcine NURR1 gene was mapped to chromosome 15. Two missense mutations were found in exon 3, the first coding exon of NURR1. Methylation analysis of the porcine NURR1 gene body revealed a high methylation degree in brain tissue, whereas methylation of the promoter was very low. A decrease in DNA methylation in a discrete region of the NURR1 promoter was observed in pig frontal cortex during pig embryo development. This observation correlated with an increase in NURR1 transcripts. Therefore, methylation might be a determinant of NURR1 expression at certain time points in embryo development. PMID- 29450129 TI - Thyroid and reproductive hormones disruption as well as kallikrein-3 level in dimethyl nitrosamine-induced toxicity: Effects of ascorbate treatment in male wistar rats. AB - Information on dimethyl nitrosamine (DMN)-induced toxicity on endocrine functions is still scanty. This study therefore investigated the outcomes of DMN-induced toxicity on endocrine (thyroid and reproductive) functions, as well as kallikrein 3 level, and effects of ascorbate treatments in male wistar rats. Thirty animals divided into six groups of five rats each were used. Group I animals were the normal control, group II animals served as vehicle control and were administered a single intraperitoneal dose of normal saline, groups III and IV were intraperitoneally injected with a single dose of 30 mg/kg DMN for 48 h, but group IV animals were post-treated orally with 5.71 mg/kg body weight (400 mg/70 kg) ascorbate for seven days, group V animals were pre-treated with same dose of ascorbate orally for seven days before intraperitoneal injection of DMN, while group VI animals were orally administered ascorbate only for seven days. Compared with control, DMN administration resulted in significant decrease (p < 0.05) in serum total cholesterol, testosterone (TST), luteinizing hormone (LH), free triiodothyronine (fT3), and kallikrein III (KLK-3) levels, as well as non significant increase in serum thyroid stimulating hormone (TSH) level. Pre treatment with ascorbate significantly increase LH and KLK-3 levels, while post treatment significantly increase fT3 level. Also, pre-treatment with ascorbate significantly reduced TSH level, while there was no significant difference in TST level following ascorbate treatments. From our findings and to some extent, ascorbate demonstrates ameliorative effects against DMN-induced hormonal disruption in male wistar rats, and this may be attributed to its antioxidant property.

PMID- 29450131 TI - Dimethyl-Benz(a)anthracene: A mammary carcinogen and a neuroendocrine disruptor. AB - Polycyclic Aromatic Hydrocarbons (PAHs) are potent carcinogens. Among these, dimethylbenz(a)anthracene (DMBA) is well known for its capacity to induce mammary carcinomas in female Sprague-Dawley (SD) rats. Ovariectomy suppresses the susceptibility of this model to DMBA, thus suggesting that the inducible action of the carcinogen depends on ovarian hormones. The promotion of DMBA-induced adenocarcinoma is accompanied by a series of neuroendocrine disruptions of both Hypothalamo-Pituitary-Gonadal (HPG) and Hypothalamo-Pituitary-Adrenal (HPA) axes and of the secretion of melatonin during the latency period of 2 months that precedes the occurrence of the first mammary tumor. The present review analyses the various neuroendocrine disruptions that occur along the HPG and the HPA axes, and the marked inhibitory effect of the carcinogen on melatonin secretion. The possible relationships between the neuroendocrine disruptions, which essentially consist in an increased pre-ovulatory secretion of 17beta-estradiol and prolactin, associated with a marked reduction of melatonin secretion, and the decrease in gene expression of the receptors for aryl-hydrocarbons receptor (AhR) and 17beta-estradiol (ERalpha; ERbeta) are also discussed.

AB - Several studies demonstrated a correlation between green tea consumption and a reduced cancer risk. Among different components, green tea polyphenols have been identified as molecules responsible for the beneficial effects showed by the green tea against oxidative stress and cell invasiveness. In this study, we investigated the effects of green tea polyphenol extracts (GTPs) in human gastric MKN-28 cell line. To this aim, we have first evaluated the effect of GTPs on oxidative stress induced cell injury. The pre-treatment with 10-4 M catechin equivalents of GTPs exerts a protective effect on xanthine-xanthine oxidase induced cell cytotoxicity, thus confirming the anti-oxidant properties of GTPs. The effect of GTPs was also extended to the invasive ability of MKN-28 cells stimulated with TNF-alpha or LPS, as pro-inflammatory factors. Migration and matrigel invasion assays demonstrated that GTPs exposure (10-6 M) prevents the increase in cell invasiveness induced by TNF-alpha or LPS. Finally, we have analyzed the effect of GTPs on the levels of Matrix Metalloproteinases (MMP)-9/2, whose expression is up-regulated by TNF-alpha or LPS. Our results indicated that the pre-treatment with GTPs was able to reduce MMP-9/2 expression at both protein and enzyme activity levels in the conditioned media of TNF-alpha or LPS stimulated MKN-28 cells. In conclusion, our results demonstrated that green tea polyphenol extract reduces the invasiveness of gastric MKN-28 cancer cells through the reduction of TNF-alpha or LPS induced MMP-9/2 up-regulation. Therefore, these data support the hypothesis that GTPs could exert a protective role against the metastatic process in gastric cancer. PMID- 29450133 TI - Inhibition of the MAPK pathway alone is insufficient to account for all of the cytotoxic effects of naringenin in MCF-7 breast cancer cells. AB - Estrogen receptor (ER) antagonists such as tamoxifen (Tam) have been used successfully to treat ER+ breast cancers for more than 30 years. Unfortunately, long term use of Tam can result in resistance. Tam resistance is associated with the activation of growth factor signaling pathways that promote cell proliferation and survival. The mitogen-activated protein kinase (MAPK), is up regulated in Tam resistant (Tam-R) cells. Previous studies have reported that the flavanone, naringenin (Nar) can inhibit cell proliferation and induce apoptosis in ER+ breast cancer cells. Furthermore, Nar has been shown to inhibit the MAPK signaling pathways in MCF-7 cells. In this report we investigated whether inhibition of MAPK alone is mediating the effects of Nar on cell proliferation and viability. These studies will determine the mechanism of action of Nar. Tam-R MCF-7 breast cancer cells were treated with Nar or U0126, a MAPK kinase inhibitor. Our studies show that while both U0126 and Nar impaired cell proliferation and viability the combination of U0126 and Nar resulted in greater inhibition of cell viability than either compound alone. It has been previously reported that Nar can bind the ER. Our lab has also shown that Nar localizes ERalpha to a peri-nuclear region of the cell. Confocal microscopy revealed that in U0126 treated cells ERalpha displayed an even distribution across the cytoplasm as seen in untreated Tam-R cells. These studies suggest that MAPK is not the only target of Nar. PMID- 29450134 TI - CRISPR/Cas9-mediated target validation of the splicing inhibitor Pladienolide B. AB - CRISPR/Cas9 system confers molecular immunity in archeal and bacterial species against invading foreign nucleic acids. CRISPR/Cas9 system is used for genome engineering applications across diverse eukaryotic species. In this study, we demonstrate the utility of the CRISPR/Cas9 genome engineering system for drug target validation in human cells. Pladienolide B is a natural macrolide with antitumor activities mediated through the inhibition of pre-mRNA splicing. To validate the spliceosomal target of Pladienolide B, we employed the CRSIPR/Cas9 system to introduce targeted mutations in the subunits of the SF3B complex in the HEK293T cells. Our data reveal that targeted mutagenesis of the SF3b1 subunit exhibited higher levels of resistance to Pladienolide B. Therefore, our data validate the spliceosomal target of Pladienolide B and provide a proof of concept on using the CRISPR/Cas9 system for drug target identification and validation. PMID- 29450135 TI - Development of a specific index to detect malnutrition in athletes: Validity in weight class or intermittent fasted athletes. AB - Fasted or weight-category athletes manage their training under strict diet conditions that could impair the stress-recovery balance and result in acute or chronic fatigue. However, to date, no validated biomarker are available to quantify this phenomena. The aim of this study was to assess the validity of a specific index combining plasma albumin and weight change to detect nutrition related risks of fatigue increase and under-performance in athletes experiencing particular nutritional conditions. An athlete's nutrition risk index (ANRI) equation, based on data from lightweight and heavyweight rowers, was developed using relationship between plasma albumin concentrations combined to weight changes with sport performance and overtraining scores and was tested by odds ratio for failure. The accuracy and sensitivity of this former specific equation was subsequently tested on runners observing the Ramadan-fasting as well as on boxers after a short weight-loss period. Independently of training and performance, lightweight rowers presented lower nutritional parameters than heavyweight (albumin: 37.4 +/- 2.7 vs 39.9 +/- 1.8 g.L-1, P < 0.05; weight state: 94.5 +/- 1.8 vs 99.9 +/- 0.9%, P < 0.01). In lightweight, ANRI was related with overtraining score (R2 = 0.21, P < 0.01), risks for failure in competition were enhanced when ANRI increased (OR:2.5, P = 0.03). Relationship of ANRI with overtraining score tended to be also significant in runners (R2 = 0.32, P = 0.06) but not in boxers (P = 0.4). Albumin concentrations combined to weight loss appeared relevant to delineate nutrition-related risks of fatigue and/or competitive failure associated with mid-term diets (about 30 days) as observed in rowers and Ramadan-fasted runners. ANRI may benefit to athletes monitoring by delineating effects of their weight loss program. PMID- 29450136 TI - Initiative action of tumor-associated macrophage during tumor metastasis. AB - Tumor-associated macrophages (TAMs) are a significant component of the microenvironment of any solid tumors in the majority of cancers, associated with unfavorable prognosis. TAMs emerge as attractive targets for therapeutic strategies aimed at reprogramming their protumor phenotype into an effective antitumor activity. In this review article, we present an overview of mechanisms responsible for TAMs recruitment and highlight the roles of TAMs in the regulation of tumor angiogenesis, invasion, metastasis, immunosuppression, and chemotherapeutic resistance. We describe the interplay between Th17 cells and other immune cells in the tumor microenvironment, and we assess both the potential antitumorigenic and pro-tumorigenic activities of Th17 cells and their associated cytokines. Understanding the nature of Th17 cell responses in the tumor microenvironment will be important for the design of more efficacious cancer immunotherapies. Finally, we discuss TAM-targeting therapy as a promising novel strategy for an indirect cancer therapy. PMID- 29450137 TI - Liver and Metformin: Lessons of a fructose diet in mice. AB - Studies show that the continuous consumption of fructose can lead to nonalcoholic fatty liver disease (NAFLD) and steatohepatitis. We aimed to investigate the role of Metformin in an animal model of liver injury caused by fructose intake, focusing on the molecular markers of lipogenesis, beta-oxidation, and antioxidant defenses. Male three months old C57BL/6 mice were divided into control group (C) and fructose group (F, 47% fructose), maintained for ten weeks. After, the groups received Metformin or vehicle for a further eight weeks: control (C), control + Metformin (CM), fructose (F), and fructose + Metformin (FM). Fructose resulted in hepatic steatosis, insulin resistance and lower insulin sensitivity in association with higher mRNA levels of proteins linked with de novo lipogenesis and increased lipid peroxidation. Fructose diminished mRNA expression of antioxidant enzymes, and of proteins responsible for mitochondrial biogenesis. Metformin reduced de novo lipogenesis and increased the expression of proteins related to mitochondrial biogenesis, thereby increasing beta-oxidation and decreasing lipid peroxidation. Also, Metformin upregulated the expression and activity of antioxidant enzymes, providing a defense against increased reactive oxygen species generation. Therefore, a significant reduction in triglyceride accumulation in the liver, steatosis and lipid peroxidation was observed in the FM group. In conclusion, fructose increases de novo lipogenesis, reduces the antioxidant defenses, and diminishes mitochondrial biogenesis. After an extended period of fructose intake, Metformin treatment, even in continuing the fructose intake, can reverse, at least partially, the liver injury and prevents NAFLD progression to more severe states. PMID- 29450138 TI - Biological activities of frankincense essential oil in human dermal fibroblasts. AB - Although frankincense essential oil (FREO) has become increasingly popular in skin care, research on its biological activities in human skin cells is scarce, if not completely absent. In the current study, we explored the biological activities of FREO in pre-inflamed human dermal fibroblasts by analyzing the levels of 17 important protein biomarkers pertinent to inflammation and tissue remodeling. FREO exhibited robust anti-proliferative activity in these skin cells. It also significantly inhibited collagen III, interferon gamma-induced protein 10, and intracellular cell adhesion molecule 1. We also studied its effect in regulating genome-wide gene expression. FREO robustly modulated global gene expression. Furthermore, Ingenuity(r) Pathway Analysis showed that FREO affected many important signaling pathways that are closely related to inflammation, immune response, and tissue remodeling. This study provides the first evidence of the biological activities of FREO in human dermal fibroblasts. Consistent with existing studies in other models, the current study suggests that FREO possesses promising potential to modulate the biological processes of inflammation and tissue remodeling in human skin. Further research into the biological mechanisms of action of FREO and its major active components is recommended. PMID- 29450139 TI - The nature of the rate-limiting step of blue multicopper oxidases: Homogeneous studies versus heterogeneous. AB - Multicopper oxidases (MCOs) catalyzed two half reactions (linked by an intramolecular electron transfer) through a Ping-Pong mechanism: the substrate oxidation followed by the O2 reduction. MCOs have been characterized in details in solution or immobilized on electrode surfaces. The nature of the rate-limiting steps, which is controversial in the literature, is discussed in this mini review for both cases. Deciphering such rate-limiting steps is of particular importance to efficiently use MCOs in any applications requiring the reduction of O2 to water. PMID- 29450140 TI - JNK3 phosphorylates Bax protein and induces ability to form pore on bilayer lipid membrane. AB - Bax is a pro-apoptotic cytosolic protein. In this work native (unphosphorylated) and JNK3 phosphorylated Bax proteins are studied on artificial bilayer membranes for pore formation. Phosphorylated Bax formed pore on the bilayer lipid membrane whereas native one does not. In cells undergoing apoptosis the pore formed by the phosphorylated Bax could be important in cytochrome c release from the mitochondrial intermembrane space to the cytosol. The low conductance (1.5 nS) of the open state of the phosphorylated Bax pore corresponds to pore diameter of 0.9 nm which is small to release cytochrome c (~3.4 nm). We hypothesized that JNK3 phosphorylated Bax protein can form bigger pores after forming complexes with other mitochondrial proteins like VDAC, t-Bid etc. to release cytochrome c. PMID- 29450141 TI - Putative roles of mitochondrial Voltage-Dependent Anion Channel, Bcl-2 family proteins and c-Jun N-terminal Kinases in ischemic stroke associated apoptosis. AB - There is a constant need for better stroke treatments. Neurons at the periphery of an ischemic stroke affected brain tissue remains metabolically active for several hours or days after stroke onset. They later undergo mitochondrion mediated apoptosis. It has been found that inhibiting apoptosis in the peripheral ischemic neurons could be very effective in the prevention of stroke progression. During stroke associated apoptosis, cytosolic c-Jun N-terminal Kinases (JNKs) and Bcl-2 family proteins translocate towards mitochondria and promote cytochrome c release by interacting with the outer mitochondrion membrane associated proteins. This review provides an overview of the plausible interactions of the outer mitochondrial membrane Voltage Dependent Anion Channel, Bcl-2 family proteins and JNKs in cytochrome c release in the peripheral ischemic stroke associated apoptotic neurons. The review ends with a note on designing new anti-stroke treatments. PMID- 29450142 TI - Arborvitae (Thuja plicata) essential oil significantly inhibited critical inflammation- and tissue remodeling-related proteins and genes in human dermal fibroblasts. AB - Arborvitae (Thuja plicata) essential oil (AEO) is becoming increasingly popular in skincare, although its biological activity in human skin cells has not been investigated. Therefore, we sought to study AEO's effect on 17 important protein biomarkers that are closely related to inflammation and tissue remodeling by using a pre-inflamed human dermal fibroblast culture model. AEO significantly inhibited the expression of vascular cell adhesion molecule 1 (VCAM-1), intracellular cell adhesion molecule 1 (ICAM-1), interferon gamma-induced protein 10 (IP-10), interferon-inducible T-cell chemoattractant (I-TAC), monokine induced by interferon gamma (MIG), and macrophage colony-stimulating factor (M-CSF). It also showed significant antiproliferative activity and robustly inhibited collagen-I, collagen-III, plasminogen activator inhibitor-1 (PAI-1), and tissue inhibitor of metalloproteinase 1 and 2 (TIMP-1 and TIMP-2). The inhibitory effect of AEO on increased production of these protein biomarkers suggests it has anti inflammatory property. We then studied the effect of AEO on the genome-wide expression of 21,224 genes in the same cell culture. AEO significantly and diversely modulated global gene expression. Ingenuity pathway analysis (IPA) showed that AEO robustly affected numerous critical genes and signaling pathways closely involved in inflammatory and tissue remodeling processes. The findings of this study provide the first evidence of the biological activity and beneficial action of AEO in human skin cells. PMID- 29450144 TI - Anti-inflammatory, tissue remodeling, immunomodulatory, and anticancer activities of oregano (Origanum vulgare) essential oil in a human skin disease model. AB - The use of oregano (Origanum vulgare) essential oil (OEO) has become popular in skin care products. However, scientific research regarding its effects on human skin cells is scarce. In this study, we investigated the biological activity of a commercially available OEO, which is high in carvacrol content, in a human skin cell disease model. OEO induced marked antiproliferative effects and significantly inhibited several inflammatory biomarkers, including monocyte chemoattractant protein 1 (MCP-1), vascular cell adhesion molecule 1 (VCAM-1), intracellular cell adhesion molecule 1 (ICAM-1), interferon gamma-induced protein 10 (IP-10), interferon-inducible T-cell alpha chemoattractant (I-TAC), and monokine induced by gamma interferon (MIG). OEO also significantly inhibited tissue remodeling biomarkers, namely collagen I, collagen III, epidermal growth factor receptor (EGFR), matrix metalloproteinase 1 (MMP-1), plasminogen activator inhibitor 1 (PAI-1), tissue inhibitor of metalloproteinase (TIMP) 1 and 2. An immunomodulatory biomarker, macrophage colony-stimulating factor (M-CSF), was also strongly inhibited by OEO treatment. In addition, OEO significantly modulated global gene expression and altered signaling pathways, many of which are critical in inflammation, tissue remodeling, and cancer signaling processes. These findings along with existing studies largely support the anti-inflammatory, tissue remodeling, immunomodulatory, and anticancer activities of OEO. In conclusion, this study provides the first evidence of the biological activity of OEO in human dermal fibroblasts. We suggest that OEO, with carvacrol as the major active component, is a promising candidate for use in skin care products with anti-inflammatory and anticancer properties. PMID- 29450143 TI - Purified horse milk exosomes contain an unpredictable small number of major proteins. AB - Exosomes are 40-100 nm nanovesicles containing RNA and different proteins. Exosomes containing proteins, lipids, mRNAs, and microRNAs are important in intracellular communication and immune function. Exosomes from different sources are usually obtained by combination of centrifugation and ultracentrifugation and according to published data can contain from a few dozens to thousands of different proteins. Crude exosome preparations from milk of eighteen horses were obtained for the first time using several standard centrifugations. Exosome preparations were additionally purified by FPLC gel filtration. Individual preparations demonstrated different profiles of gel filtration showing well or bad separation of exosome peaks and one or two peaks of co-isolating proteins and their complexes. According to the electron microscopy, well purified exosomes displayed a typical exosome-like size (30-100 nm) and morphology. It was shown that exosomes may have several different biological functions, but detection of their biological functions may vary significantly depending on the presence of exosome contaminating proteins and proteins directly into exosomes. Exosome proteins were identified before and after gel filtration by MALDI MS and MS/MS spectrometry of protein tryptic hydrolyzates derived by SDS PAGE and 2D electrophoresis. The results of protein identification were unexpected: one or two peaks co-isolating proteins after gel-filtration mainly contained kappa-, beta-, alpha-S1-caseins and its precursors, but these proteins were not found in well-purified exosomes. Well-purified exosomes contained from five to eight different major proteins: CD81, CD63 receptors, beta-lactoglobulin and lactadherin were common to all preparations, while actin, butyrophilin, lactoferrin, and xanthine dehydrogenase were found only in some of them. The article describes the morphology and the protein content of major horse milk exosomes for the first time. Our results on the decrease of major protein number identified in exosomal preparations after gel filtration may be important to the studies of biological functions of pure exosomes. PMID- 29450145 TI - Phosphorylation of purified mitochondrial Voltage-Dependent Anion Channel by c Jun N-terminal Kinase-3 modifies channel voltage-dependence. AB - Voltage-Dependent Anion Channel (VDAC) phosphorylated by c-Jun N-terminal Kinase 3 (JNK3) was incorporated into the bilayer lipid membrane. Single-channel electrophysiological properties of the native and the phosphorylated VDAC were compared. The open probability versus voltage curve of the native VDAC displayed symmetry around the voltage axis, whereas that of the phosphorylated VDAC showed asymmetry. This result indicates that phosphorylation by JNK3 modifies voltage dependence of VDAC. PMID- 29450146 TI - Novel proteins from proteomic analysis of the trunk disease fungus Lasiodiplodia theobromae (Botryosphaeriaceae). AB - Many basic science questions remain regarding protein functions in the pathogen: host interaction, especially in the trunk disease fungi family, the Botryosphaeriaceae, which are a global problem for economically important plants, especially fruiting trees. Proteomics is a highly useful technology for studying protein expression and for discovering novel proteins in unsequenced and poorly annotated organisms. Current fungal proteomics approaches involve 2D SDS-PAGE and extensive, complex, protein extraction methodologies. In this work, a modified Folch extraction was applied to protein extraction to perform both de novo peptide sequencing and peptide fragmentation analysis/protein identification of the plant and human fungal pathogen Lasiodiplodia theobromae. Both bioinformatics approaches yielded novel peptide sequences from proteins produced by L. theobromae in the presence of exogenous triglycerides and glucose. These proteins and the functions they may possess could be targeted for further functional characterization and validation efforts, due to their potential uses in biotechnology and as new paradigms for understanding fungal biochemistry, such as the finding of allergenic enolases, as well as various novel proteases, including zinc metalloproteinases homologous to those found in snake venom. This work contributes to genomic annotation efforts, which, hand in hand with genomic sequencing, will help improve fungal bioinformatics databases for future studies of Botryosphaeriaceae. All data, including raw data, are available via the ProteomeXchange data repository with identifier PXD005283. This is the first study of its kind in Botryosphaeriaceae. PMID- 29450147 TI - Lemongrass (Cymbopogon flexuosus) essential oil demonstrated anti-inflammatory effect in pre-inflamed human dermal fibroblasts. AB - Lemongrass (Cymbopogon flexuosus) essential oil (LEO), which has citral as its main component, has exhibited anti-inflammatory effect in both animal and human cells. In this study, we evaluated the anti-inflammatory activity of a commercially available LEO in pre-inflamed human dermal fibroblasts. We first studied the impact of LEO on 17 protein biomarkers that are critically associated with inflammation and tissue remodeling. LEO significantly inhibited production of the inflammatory biomarkers vascular cell adhesion molecule 1 (VCAM-1), interferon gamma-induced protein 10 (IP-10), interferon-inducible T-cell alpha chemoattractant (I-TAC), and monokine induced by gamma interferon (MIG); decreased levels of the tissue remodeling biomarkers collagen-I and III, epidermal growth factor receptor (EGFR), and plasminogen activator inhibitor (PAI 1); and inhibited the immunomodulatory biomarker macrophage colony-stimulating factor (M-CSF). Furthermore, we studied the impact of LEO on genome-wide gene expression profiles. LEO significantly modulated global gene expression and robustly impacted signaling pathways, many of which are critical for inflammation and tissue remodeling processes. This study provides the first evidence of the anti-inflammatory activity of LEO in human skin cells and indicates that it is a good therapeutic candidate for treating inflammatory conditions of the skin. PMID- 29450148 TI - The effect of endurance training with and without vitamin E on expression of p53 and PTEN tumor suppressing genes in prostate glands of male rats. AB - The aim of this study was to investigate the effect of endurance training with and without vitamin E on the expression of p53 and Phosphatase and tension homolog (PTEN) tumor suppressor genes of prostate glands in male rats. For this purpose, 50 Sprague-Dawley male rats were randomly assigned into 5 groups: (1) control group (CON, n = 10), (2) sham (S, n = 10), (3) endurance training (ET, n = 10), (4) endurance training + vitamin E (ET + VE, n = 10), (5) vitamin E (VE, n = 10). Endurance training protocol was implemented for 6 weeks, 6 days per week, in accordance with the overload principle. To measure expression changes of p53 and PTEN genes in rats' prostate, real-time PCR method was used and HPLC method was used to measure vitamin E in this tissue. After 6 weeks of taking vitamin E, its level in all groups, except for group VE (p < 0.000) did not significantly increase. After implementing training protocol, p53 expression reduced significantly in ET group (p < 0.026). Vitamin E supplementation along with endurance training did not cause any significant change either p53 or PTEN (respectively; p < 0.2, p < 0.11). Instead, vitamin E supplementation without endurance training caused significant increase in PTEN, but did not cause any significant changes in p53 (respectively; p < 0.016, p < 0.15). These results indicate that endurance training reduces p53 and PTEN tumor suppressing genes expression, and taking vitamin E supplement could increase expression of these genes in some extent. PMID- 29450149 TI - Human and mouse microarrays-guided expression analysis of membrane protein trafficking-related genes in MDCK cells, a canine epithelial model for apical and basolateral differential protein targeting. AB - MDCK cells are widely used to study the differential targeting of membrane transporters to apical and basolateral membrane but its canine origin limited the commercial tools available for the analysis of protein trafficking machinery. Because apical and basolateral membranes are only found in differentiated epithelial cells, genes critical for differential targeting may be specifically up-regulated upon MDCK cell differentiation. To search for these genes, a cross species screening strategy was used. We first analyzed the human microarray data for protein trafficking-related genes that were up-regulated in colon carcinoma Caco2 cells upon differentiation. The results of mouse 44K gene expression microarray analysis were then used to extract additional candidate genes that showed higher expression in normal colon epithelium compared to primary embryonic fibroblasts. Finally, NCBI genomic sequence information was used to design RT-PCR primers for 13 candidate and 10 negative control genes and used to analyze MDCK cells at 2, 13 and 17 days after seeding. To determine whether the gene up regulation was specific in epithelial differentiation, we also performed RT-PCR on rat non-differentiating intestinal IEC-6 cells and mouse C2C12 cells, a differentiating myoblast model. Of the 13 candidate genes, 3 genes, SDCBP2, KIF12, KIF27, met all criteria of specific up-regulation in differentiated MDCK cells. In addition, KIF13A showed up-regulation in differentiated MDCK and C2C12 cells but not in IEC-6 cells cultured for the same duration. The functions of these genes need to be analyzed in the future. This cross-species screening strategy may be useful for other non-human, non-rodent cell models. PMID- 29450150 TI - Chemical composition analysis and in vitro biological activities of ten essential oils in human skin cells. AB - Research on the biological effects of essential oils on human skin cells is scarce. In the current study, we primarily explored the biological activities of 10 essential oils (nine single and one blend) in a pre-inflamed human dermal fibroblast system that simulated chronic inflammation. We measured levels of proteins critical for inflammation, immune responses, and tissue-remodeling processes. The nine single oils were distilled from Citrus bergamia (bergamot), Coriandrum sativum (cilantro), Pelargonium graveolens (geranium), Helichrysum italicum (helichrysum), Pogostemon cablin (patchouli), Citrus aurantium (petitgrain), Santalum album (sandalwood), Nardostachys jatamansi (spikenard), and Cananga odorata (ylang ylang). The essential oil blend (commercial name Immortelle) is composed of oils from frankincense, Hawaiian sandalwood, lavender, myrrh, helichrysum, and rose. All the studied oils were significantly anti proliferative against these cells. Furthermore, bergamot, cilantro, and spikenard essential oils primarily inhibited protein molecules related to inflammation, immune responses, and tissue-remodeling processes, suggesting they have anti inflammatory and wound healing properties. Helichrysum and ylang ylang essential oils, as well as Immortelle primarily inhibited tissue remodeling-related proteins, suggesting a wound healing property. The data are consistent with the results of existing studies examining these oils in other models and suggest that the studied oils may be promising therapeutic candidates. Further research into their biological mechanisms of action is recommended. The differential effects of these essential oils suggest that they exert activities by different mechanisms or pathways, warranting further investigation. The chemical composition of these oils was analyzed using gas chromatography-mass spectrometry. PMID- 29450151 TI - Comparison of antimicrobial activities of natural essential oils and synthetic fragrances against selected environmental pathogens. AB - Plant essential oils (EOs) are known to inhibit the growth of bacteria and fungi. Whether these antimicrobial effects are comparable to synthetic household products is less clear. Furthermore, limited research is available on the potential additive effect of blending EOs. In this investigation, a new EO blend containing orange, patchouli, peppermint, and clary sage was compared to its individual single oils and to three household products-air freshener, liquid soap, and body spray-for their ability to inhibit the growth of Staphylococcus aureus, Streptococcus pneumoniae, Pseudonomas aeruginosa, and Aspergillus brasiliensis in the disc-diffusion assay. The new EO blend significantly inhibited the growth of the four microorganisms. The zones of inhibition of new EO blend were greater than the air freshener and similar to the liquid soap and body spray, with the exception of Str. pneumoniae in which the body spray provided greater inhibitory zone. The new EO blend and the single oils, with the exception of peppermint, equally inhibited the growth of S. aureus and Str. pneumoniae suggesting no additive effect. P. aeruginosa and A. brasiliensis showed variable susceptibility to all EOs except for no susceptibility to orange and limonene. No difference was found between (-) and (+)-limonene; whereas, (+) menthol showed greater effect than (-)-menthol. In conclusion, blending the EO of orange, patchouli, peppermint, and clary sage was beneficial in inhibiting the growth of S. aureus, Str. pneumoniae, P. aeruginosa, and A. brasiliensis providing a natural antimicrobial fragrance option over synthetics fragrances used in soaps, body sprays, and air fresheners. PMID- 29450152 TI - A welcome to the new journal, International Journal of Cardiology - Heart and Vessels (IJC-H + V). AB - A new journal has been launched: IJC - Heart and Vessels [1]. It builds upon the success of the main journal International Journal of Cardiology. As an introduction to the new journal we will be publishing a series of summaries of the topics to be covered, highlighting the most important papers in the field that have been published recently in the main journal, International Journal of Cardiology. This article describes a topic review of congenital heart disease. IJC has become one of the most important sources of quality papers in this field and many excellent publications have been published in the main journal. The expansion of space occasioned by the launch of IJC - Heart and Vessels will allow us to publish more high quality papers in the expanding field of congenital heart disease. PMID- 29450153 TI - Gender related predictors of limited exercise capacity in heart failure. AB - Aim: The aim of this study was to investigate the impact of gender on the prediction of limited exercise capacity in heart failure (HF) patients assessed by 6 minute walk test (6-MWT). Methods: In 147 HF patients (mean age 61 +/- 11 years, 50.3% male), a 6-MWT and a Doppler echocardiographic study were performed in the same day. Conventional cardiac measurements were obtained and global LV dyssynchrony was indirectly assessed using total isovolumic time - t-IVT [in s/min; calculated as: 60 - (total ejection time - total filling time)] and Tei index (t-IVT/ejection time). Patients were divided into two groups according to gender, which were again divided into two subgroups based on the 6-MWT distance (Group I: <= 300 m, and Group II: > 300 m). Results: Female patients were younger (p = 0.02), and had higher left ventricular (LV) ejection fraction - EF (p = 0.007) but with similar 6-MWT distance to male patients (p = 68). Group I male patients had lower hemoglobin level (p = 0.02) and lower EF (p = 0.03), compared with Group II, but none of the clinical or echocardiographic variables differed between groups in female patients. In multivariate analysis, only t-IVT [0.699 (0.552-0.886), p = 0.003], and LV EF [0.908 (0.835-0.987), p = 0.02] in males, and NYHA functional class [4.439 (2.213-16.24), p = 0.02] in females independently predicted poor 6-MWT distance (< 300 m). Conclusion: Despite similar limited exercise capacity, gender determines the pattern of underlying cardiac disturbances; ventricular dysfunction in males and subjective NYHA class in female heart failure patients. PMID- 29450154 TI - Are ICD recipients able to foresee if they want to withdraw therapy or deactivate defibrillator shocks? AB - Background: Expert consensus statements on management of implantable cardioverter defibrillators (ICDs) emphasize the importance of having discussions about deactivation before and after implantation. These statements were developed with limited patient input. The purpose of this study was to identify the factors associated with patients' experiences of end-of-life discussions, attitudes towards such discussions, and attitudes towards withdrawal of therapy (i.e., generator replacement and deactivation) at end-of-life, in a large national cohort of ICD-recipients. Methods: We enrolled 3067 ICD-patients, administrating the End-of-Life-ICD-Questionnaire. Results: Most (86%) had not discussed ICD deactivation with their physician. Most (69%) thought discussions were best at end-of-life, but 40% stated that they never wanted the physician to initiate a discussion. Those unwilling to discuss deactivation were younger, had experienced battery replacement, had a longer time since implantation, and had better quality of-life. Those with psychological morbidity were more likely to desire a discussion about deactivation. Many patients (39%) were unable to foresee what to decide about deactivation in an anticipated terminal condition. Women, those without depression, and those with worse ICD-related experiences were more indecisive about withdrawal of therapy. Irrespective of shock experiences, those who could take a stand regarding deactivation chose to keep shock therapies active in many cases (39%). Conclusions: Despite consensus statements recommending discussions about ICD-deactivation at the end-of-life, such discussion usually do not occur. There is substantial ambivalence and indecisiveness on the part of most ICD-patients in this nationwide survey about having these discussions and about expressing desires about deactivation in an anticipated end-of-life situation. PMID- 29450155 TI - Seven-year follow-up of percutaneous closure of patent foramen ovale. AB - Background: Observational studies favor percutaneous closure of patent foramen ovale (PFO) over medical treatment to reduce recurrent stroke while randomized trials fail to demonstrate significant superiority of percutaneous PFO closure. Few long-term studies are available post PFO closure. This study reports long term clinical outcomes after percutaneous PFO closure. Methods: Between 1997 and 2006, 86 consecutive eligible patients with cerebrovascular events, presumably related to PFO, underwent percutaneous PFO closure. All 86 patients were invited to a long-term follow-up, which was carried out during 2011 and 2012. Results: Percutaneous PFO closure was successfully performed in 85 of 86 patients. The follow-up rate was 100%. No cardiovascular or cerebrovascular deaths occurred. Two patients (both women) died from lung cancer during follow-up. Follow-up visits were conducted for 64 patients and the remaining 20 patients were followed up by phone. The mean follow-up time was 7.3 years (5 to 12.4 years). Mean age at PFO closure was 49 years. One patient had a minor stroke one month after PFO closure and a transient ischemic attack (TIA) two years afterwards. One other patient suffered from a TIA six years after closure. No long-term device-related complications were observed. Conclusions: Percutaneous PFO closure was associated with very low risk of recurrent stroke and is suitable in most patients. We observed no mortality and no long-term device-related complications related to PFO closure, indicating that percutaneous PFO closure is a safe and efficient treatment even in the long term. PMID- 29450156 TI - Clinical Efficacy and Safety of SeQuent Please Paclitaxel-Eluting Balloon in a Real-World Single-Center Registry of South-East Asian Patients. AB - Background: Drug eluting balloon (DEB) is a new therapeutic option for treatment of obstructive coronary lesions in percutaneous coronary intervention (PCI). There is limited data on the safety and efficacy of DEB in Asian patients in contemporary clinical registries. We evaluated the clinical efficacy and safety of SeQuent Please paclitaxel-eluting balloon in our cohort of South-East Asian patients in real world clinical practice. Methods: Between January 2010 to November 2012, 320 patients (76% male, mean age 61.3 +/- 11.2 years) with a total of 337 coronary lesions were treated with SeQuent Please drug-eluting balloon (DEB). The primary endpoint was major adverse cardiac events (MACE) ie a composite of cardiovascular death, target vessel related myocardial infarction (MI) and target lesion revascularization (TLR) at 9 months follow-up. Results: The majority of patients presented with acute coronary syndrome (76%).The most common indication for the use of DEB was small vessel disease (54%) followed by instent restenosis (21%), bifurcation lesions (6%) and others (19%). An average of 1.23 +/- 0.5 DEB were used per patient, with mean DEB diameter of 2.6 +/- 0.6 mm and average total length of 24.0 +/- 11.1 mm.At 9 months follow-up, 5.3% of patients developed MACE. MACE was mainly driven by TLR(4%) followed by target vessel related myocardial infarction (2.6%) and cardiovascular death (1%). Conclusion: SeQuent Please DEB was a safe and effective treatment modality in our cohort of South-East Asian patients with a low incidence of MACE observed at 9 months follow-up. PMID- 29450158 TI - Associations between the consumption of different kinds of seafood and out-of hospital cardiac arrests of cardiac origin in Japan. AB - Background: Prospective cohort studies have shown that seafood consumption is inversely related to fatal coronary heart disease, sudden cardiac death and stroke. We studied whether the kind of seafood consumed in addition to seafood consumption per se is associated with out-of-hospital cardiac arrests (OHCA) of cardiac origin. Methods and results: We compared the average consumption of different kinds of seafood and other risk factors to the average incidence of age adjusted OHCA (660,672 cases of OHCA: 55.2% of cardiac origin and 44.8% of non cardiac origin) between 2005 and 2010 in the 47 prefectures of Japan. There were many significant correlations between the incidence of age-adjusted OHCA of cardiac origin (ad-OHCA-CO) and the consumption of many kinds of seafood, but not the total consumption of seafood. The consumption of horse mackerel (r = - 0.568, p < 0.0001) and saury (r = 0.607, p < 0.0001) showed the highest negative and positive correlations, respectively, with the age-adjusted incidence of ad-OHCA CO. Conclusions: In Japan, the consumption of different kinds of seafood may be an important factor in OHCA of cardiac origin. Thus, dietary habits with regard to seafood may play a role in OHCA of cardiac origin, however, the question of whether to eat fish in general or instead to eat certain kinds of fish is still unclear. PMID- 29450159 TI - Association between heart calcification assessed by echocardiography and future cardiovascular disease mortality and morbidity. AB - Background: Echocardiography can detect calcium deposits in heart valves and aortic root, but the relationship of echocardiographic heart calcification such as aortic valve calcification (AVC), mitral annular calcification (MAC), and aortic root calcification (ARC) with future cardiovascular disease (CVD) mortality and morbidity is not fully elucidated. Methods: We analyzed data from 943 patients with suspected coronary heart disease (mean age, 65.7 years; 36% female). Echocardiographic total heart calcification (THC) score was determined by summing up the AVC, MAC, and ARC variables; THC-0 (N = 397), THC-1 (N = 236), THC-2 (N = 224), and THC-3 (N = 86). Subjects were followed for mean 2.9 years to assess the risk of death from CVD causes. Cardiovascular morbidity was defined as new episodes of non-fatal myocardial infarction, congestive heart failure, stroke, and surgical treatment of vascular disease. Results: There were 43 CVD deaths and a total of 160 CVD events. Kaplan-Meier curves showed a graded CVD mortality and morbidity across increasing THC score values. With full adjustment, Cox regression hazard ratios (95% confidence intervals) for CVD mortality and morbidity, using no calcification as reference, for THC-1, THC-2, and THC-3 were 2.21 (1.31-3.74), 2.59 (1.53-4.39) and 4.14 (2.30-7.47), respectively. When THC score was added to models with CVD risk factors, C-statistics were significantly larger for CVD mortality (p = 0.048) and for CVD mortality and morbidity (p = 0.004). Conclusions: THC score, the sum of the amounts of AVC, MAC, and ARC present as estimated by echocardiography, has an independent and incremental prognostic value in a high-risk population. PMID- 29450157 TI - Cardiac disease in children and young adults with various lysosomal storage diseases: Comparison of echocardiographic and ECG changes among clinical groups. AB - Background: Lysosomal storage disease (LSD) is a rare inherited disease group. Consecutively there are few data on cardiac changes in mucopolysaccharidosis (MPS), Anderson Fabry disease (AFD), and other LSD (oLSD) including Pompe disease (PD) and Danon disease (DD), I-cell disease ICD and mucolipidosis III (ML III). Methods: Between 1994 and 2011, we identified 39 patients with LSD: 25 with MPS, 8 with AFD, and 6 with oLSD including PD (1), ML III (2), DD (1), and ICD (2) at our institution fulfilling the inclusion criteria of at least one echocardiogram and ECG. Results: Median age was 11.4 years (range: 2-27), 22 were females (56%). Normal echocardiograms were present in 12 patients (31%): 4 with MPS (16%), 7 AFD (88%), and 1 oLSD (17%). Valvular heart disease was present in 23 patients (59%) occurring more often in MPS (76%) and oLSD (67%) than in AFD (0%) (p < 0.001). The most common ECG abnormality was a short PR interval in 10 of 35 patients (29%) occurring in all LSD groups. Median follow-up was 5.8 (0.2-22.2) years showing diminished 5-year survival compared to an age-matched group. However, no patient died due to a cardiac cause and no cardiovascular intervention was necessary. Conclusion: Echocardiographically detectable cardiovascular involvement in children with LSD is mostly confined to MPS and oLSD. Valve thickening in echo and a short PR interval in the ECG are the most frequent abnormalities. Routine repeat assessment is recommended in LSD. However, significant cardiac disease necessitating cardiac intervention is rare during a short follow-up.

PMID- 29450161 TI - Early transcatheter heart valve thrombosis detected by multidetector computed tomography. PMID- 29450162 TI - The predictive value of arterial and valvular calcification for mortality and cardiovascular events. AB - A review of the predictive ability of arterial and valvular calcification has shown an additive effect of calcification in more than 1 location in predicting mortality and coronary heart disease, with mitral annual calcification being a particularly strong predictor. In individual arteries and valves there is a clear association between calcification presence, extent and progression and future cardiovascular events and mortality in asymptomatic, symptomatic and high risk patients, although adjustment for calcification in other arterial beds generally renders associations non-significant. Furthermore, in acute coronary syndrome, culprit plaque is normally not calcified. This would tend to reduce the validity of calcification as a predictor and suggest that the association with cardiovascular events and mortality may not be causal. The association with stroke is less clear; carotid and intracranial artery calcification show little predictive ability, with symptomatic plaques tending to be uncalcified. PMID- 29450163 TI - Mineralocorticoid receptor antagonist in heart failure: Past, present and future perspectives. AB - Aldosterone is involved in various deleterious effects on the cardiovascular system, including sodium and fluid retention, myocardial fibrosis, vascular stiffening, endothelial dysfunction, catecholamine release and stimulation of cardiac arrhythmias. Therefore, aldosterone receptor blockade may have several potential benefits in patients with cardiovascular disease. Mineralocorticoid receptor antagonists (MRAs) have been shown to prevent many of the maladaptive effects of aldosterone, in particular among patients with heart failure (HF). Randomized controlled trials have demonstrated efficacy of MRA in heart failure with reduced ejection fraction, both in patients with NYHA functional classes III and IV and in asymptomatic and mildly symptomatic patients (NYHA classes I and II). Recent data in patients with heart failure with preserved ejection fraction are encouraging. MRA could also have anti-arrhythmic effects on atrial and ventricular arrhythmias and may be helpful in patient ischemic heart disease through prevention of myocardial fibrosis and vascular damage. This article aims to discuss the pathophysiological effects of aldosterone in patients with cardiovascular disease and to review the current data that support the use of MRA in heart failure. PMID- 29450164 TI - Late gadolinium enhancement (LGE) progresses with right ventricle volume in children after repair of tetralogy of fallot. AB - Background: Fibrosis after myocardial damage can be determined by cardiac magnetic resonance (CMR) with late gadolinium enhancement (LGE). We studied whether ventricular LGE is visible in the ventricles of pediatric and adolescent TOF (tetralogy of Fallot) patients by measuring LGE and investigating whether fibrosis correlated with right ventricular volume, pulmonary regurgitation, N terminal pro-brain natriuretic peptide (NT-proBNP) or the aminoterminal propeptide of type III procollagen (PIIINP). We also studied if the patient's age, post-operative follow-up time or surgical history would affect LGE. Methods: A total of 40 pediatric patients who had undergone TOF repair and 43 healthy age and gender matched controls underwent a CMR study, whereby LGE was scored in the right (RV) and the left ventricle. To exclude the possible iatrogenic scarring we calculated the LGE score by excluding the right ventricular outflow tract and VSD patch region. Results: All patients had RV LGE and in 39 of 40 it was seen also outside the surgically affected areas. The amount of LGE correlated positively with the RV end-diastolic volume (r = 0.44, P = 0.0045), pulmonary regurgitation (r = 0.40, P = 0.013), and with NT-proBNP. The presence of LGE also depended on post-operative follow-up time (r = 0.53, P = 0.006). PIIINP levels of TOF patients were significantly higher than in the control subjects but it did not correlate with LGE or with any of the studied clinical markers. Conclusions: LGE is present globally in the right ventricular muscle in children and adolescents with TOF. The longer the follow-up time the more common was the LGE in the right ventricle. PMID- 29450165 TI - Difference of vascular response between everolimus- and paclitaxel-eluting stents for small coronary artery disease: Optical coherence tomography analysis. AB - Background: Previous clinical trials have demonstrated the clinical and angiographic superiority of everolimus-eluting stents (EES) compared with paclitaxel-eluting stents (PES) in the small coronary vessel. However, the differences of vascular response including assessment of morphological neointimal tissue (NIT) characteristics using optical coherence tomography (OCT) have not been fully evaluated. The aim of this study is to evaluate the differences of chronic vascular response following small coronary stenting between EES and PES using OCT. Methods and results: A prospective OCT examination at 9 month follow up was performed for 50 small coronary artery diseases (50 patients) treated by a single 2.5 mm stent for each stent group. Cross-sectional area within stent segments were analyzed at an interval of 1 mm. NIT structure (homogeneous or heterogeneous) was evaluated for qualitative assessment. Homogeneous NIT was observed significantly higher and heterogeneous NIT was lower in EES compared with PES (93% vs. 89%; p = 0.003, 6.5% vs. 10.3%; p = 0.002, respectively). The frequencies of exposed and malapposed struts were lower in EES compared with PES (0.2% vs. 1.7%; p = 0.0001, 0.1% vs. 0.3%; p = 0.001, respectively). NIT eccentricity index and NIT area were lower in EES compared with PES (0.69 +/- 0.08 vs. 0.76 +/- 0.10; p = 0.001, 0.97 +/- 0.42 mm2 vs. 1.27 +/- 0.67 mm2; p = 0.01, respectively). Conclusions: A favorable vascular response was observed after EES implantation compared with PES for small coronary artery disease. In addition, the characteristics of NIT after EES implantation were more stable than PES at 9 month follow-up. PMID- 29450166 TI - Progress of right ventricular dilatation in adults with repaired tetralogy of Fallot and free pulmonary regurgitation. AB - Background: The time course of progressive dilatation of the right ventricle (RV) in adults with pulmonary regurgitation (PR) late after repair of tetralogy of Fallot (TOF) is poorly characterized. Methods: We analysed cardiac MRI data (1.5 T) from 14 adult repaired TOF patients (26 +/- 11 years of age) with dilated RVs and known significant PR, on 2 separate visits with a between MRI period of 2.1 +/- 1.0 years. Results: Indexed RV end diastolic volume (RVEDVi) increased over 2 years (142 +/- 19 to 151 +/- 20 mL/m2, p = 0.005; change = 8.4 +/- 9.3 mL/m2, range = - 6 to 26 mL/m2; annual mL/m2 increase = 4.3 +/- 4.6; annual percentage increase = 3.1 +/- 3.3%), whilst RV ejection fraction decreased (53 +/- 8 to 49 +/- 7 %, p = 0.039). RV muscular corpus (RVMC) EDVi significantly increased (130 +/- 19 to 138 +/- 20 mL/m2, p = 0.014), whereas RV outflow tract (RVOT) EDVi did not (12 +/- 7 vs 13 +/- 6 mL/m2, p = 0.390). No other RV or LV measures significantly changed during the inter-MRI period. The change in RVEDVi correlated significantly with LV end diastolic volume (r = - 0.582, p = 0.029), RVEDVi:LVEDVi (r = 0.6, p = 0.023) and RVMC EDVi (r = 0.9, p < 0.001) but not RVOT EDVi (r = 0.225, p = 0.459). Conclusions: Adult repaired TOF patients with free PR experienced a mean 3.1%, or 4.3 mL/m2, annual increase in RVEDVi, unrelated to the initial RVEDVi or PR fraction. The increase in RVEDVi was due to RVMC rather than RVOT dilatation. This provides a guide to the frequency of MR surveillance and insights into the natural history of progressive RV dilatation in this setting. PMID- 29450167 TI - Repair or prosthesis insertion in ischemic mitral regurgitation: Two faces of the same medal. AB - Objective: The proper treatment of chronic ischemic mitral regurgitation (CIMR) is still under evaluation. The different role of mitral valve repair (MVr) or mitral valve prosthesis insertion (MVPI) is still not defined. Methods: From May 2009 to December 2011 167 patients with ejection fraction (EF) <= 40% had MV surgery for CIMR, MVr in 135 (80.8%) and MVPI in 32 (19.2%). Indication to MVPI was a MV coaptation depth > 10 mm. EF was lower (26 +/- 7 vs 32 +/- 6, p = 0.0000) in MVPI, whereas MR grade (3.6 +/- 0.8 vs 2.7 +/- 0.9, p = 0.0000), left ventricle dimensions (end diastolic, LVEDD, 62 +/- 7 vs 57 +/- 6 mm, p = 0.0001; end systolic, LVESD, 49 +/- 8 vs 44 +/- 8 mm, p = 0.0018), systolic pulmonary artery pressure (51 +/- 22 vs 41 +/- 16 mm Hg, p = 0.0037) and NYHA Class (3.6 +/ 0.5 vs 2.8 +/- 0.6, p = 0.0000) were higher. Results: In-hospital mortality was similar (3.1 vs 3.7%) as well as 3-year survival (86 +/- 6 vs 88 +/- 4) and survival in NYHA Class I/II (80 +/- 5 vs 83 +/- 4). One hundred thirty nine patients had an echocardiographic evaluation after a minimum of 4 months (13 +/- 8). EF rose significantly in both groups (from 26 +/- 7% to 30 +/- 4%, p = 0.0122, and from 32 +/- 6% to 35 +/- 8%, p = 0.0018). LVESD reduced significantly in both groups (from 49 +/- 8 to 43 +/- 9 mm, p = 0.0109, and from 44 +/- 8 to 41 +/- 7 mm, p = 0.0033). MR grade was significantly lower in patients who had MVPI (0.1 +/- 0.2 vs 0.3 +/- 0.3, p = 0.0011). Conclusions: With appropriate indications, MVPI is a safe procedure which provides similar results to MVr with lower MR return, even if addressed to patients with worse preoperative parameters. PMID- 29450168 TI - Guideline-directed medical therapy for secondary prevention after coronary artery bypass grafting in patients with depression. AB - Background: We hypothesized that depressed patients would have lower use of guideline-directed medical therapy for secondary prevention of cardiovascular events following coronary artery bypass grafting (CABG). Methods: We included all patients who underwent primary isolated CABG in Sweden between 2006 and 2008. We cross-linked individual level data from national Swedish registers. Preoperative depression was defined as at least one antidepressant prescription dispensed before surgery. We defined medication use as at least two dispensed prescriptions in each medication class (antiplatelet agents, beta-blockers, angiotensin converting enzyme inhibitors (ACEI)/angiotensin II receptor blocker (ARB), and statins) within a rolling 12 month period. We calculated adjusted risk ratios (RR) for the use of each medication class, and for all four classes, after one and four years, respectively. Results: During the first year after CABG, 93% of all patients (n = 10,586) had at least two dispensed prescriptions for an antiplatelet agent, 68% for an ACEI/ARB, 91% for a beta-blocker, and 92% for a statin. 57% had prescriptions for all four medication classes. After four years (n = 4034), 44% had filled prescriptions for all four medication classes. Preoperative depression was not significantly associated with a lower use of all four medication classes after one year (RR 0.98, 95% confidence interval (CI) 0.93-1.03) or after four years (RR 0.97, 95% CI 0.86-1.09). Conclusions: Preoperative depression was not associated with lower use of guideline-directed medical therapy for secondary prevention after CABG. These findings suggest that the observed higher mortality following CABG among depressed patients is not explained by inadequate secondary prevention medication. PMID- 29450169 TI - Efficacy of non-compliant balloon post-dilation in optimization of contemporary stents: A digital stent enhancement study. AB - Background: There is no evidence from randomized trials for the benefit of routine non-compliant balloon (NCB) post-dilation after stent deployment. Despite being the gold standard, intravascular ultrasound is infrequently performed due to time and cost constraints and a suitable alternative technology is required for routine assessment of stent expansion. The purpose of this study was to assess the contribution of NCB post-dilation in optimizing contemporary stents by using digital stent enhancement (DSE). Methods: We treated 120 patients with stent insertion and assessed the stents with DSE before and after NCB use. Optimal expansion was defined as the minimum stent diameter (MSD) >= 90% of the nominal stent diameter, an adaptation of the MUSIC and POSTIT trial criteria. Stent deployment was performed at 12 atm pressure followed by routine NCB post dilation at >= 14 atm. Results: The mean reference diameter on QCA was 2.75 mm (SD 0.63) and mean stent diameter was 3.15 mm (SD 0.46). At a mean stent deployment pressure of 11.7 atm (SD 2.4), only 21% of stents were optimally expanded. After NCB inflation at a mean of 16.9 atm (SD 2.8), MSD increased by 0.26 mm (SD 0.24), optimal stent expansion increased from 21% to 58% and mean stent symmetry ratio increased from 0.83 to 0.87 (p < 0.0001). Conclusions: Contemporary stents are sub-optimally expanded in the majority of cases after standard deployment compared with nominal sizes. Adjunctive NCB post-dilation optimized an additional 37% of stents. DSE analysis can assist in qualitative and quantitative stent assessments and can potentially facilitate a selective NCB post-dilation strategy to achieve optimal stent expansion. PMID- 29450170 TI - Corticosteroids increase intracellular free sodium ion concentration via glucocorticoid receptor pathway in cultured neonatal rat cardiomyocytes. AB - Background: Glucocorticoids as well as mineralocorticoid have been shown to play essential roles in the regulation of electrical and mechanical activities in cardiomyocytes. Excess of these hormones is an independent risk factor for cardiovascular disease. Intracellular sodium ([Na+]i) kinetics are involved in cardiac diseases, including ischemia, heart failure and hypertrophy. However, intrinsic mediators that regulate [Na+]i in cardiomyocytes have not been widely discussed. Moreover, the quantitative estimation of altered [Na+]i in cultured cardiomyocytes and the association between the level of [Na+]i and the severity of pathological conditions, such as hypertrophy, have not been precisely reported. Methods and results: We herein demonstrate the quantitative estimation of [Na+]i in cultured neonatal rat cardiomyocytes following 24 h of treatment with corticosterone, aldosterone and dexamethasone. The physiological concentration of glucocorticoids increased [Na+]i up to approximately 2.5 mM (an almost 1.5-fold increase compared to the control) in a dose-dependent manner; this effect was blocked by a glucocorticoid receptor (GR) antagonist but not a mineralocorticoid receptor antagonist. Furthermore, glucocorticoids induced cardiac hypertrophy, and the hypertrophic gene expression was positively and significantly correlated with the level of [Na+]i. Dexamethasone induced the upregulation of Na+/Ca2 + exchanger 1 at the mRNA and protein levels. Conclusions: The physiological concentration of glucocorticoids increases [Na+]i via GR. The dexamethasone-induced upregulation of NCX1 is partly involved in the glucocorticoid-induced alteration of [Na+]i in cardiomyocytes. These results provide new insight into the mechanisms by which glucocorticoid excess within a physiological concentration contributes to the development of cardiac pathology. PMID- 29450171 TI - Study of vitamin D deficiency prevalence in acute myocardial infarction. AB - Background: Deficiency of 25-hydroxy vitamin D [25(OH)D] is a treatable condition that has been associated with coronary artery disease and many of its risk factors. A practical time to assess for 25(OH)D deficiency, and to initiate treatment, is at the time of an acute myocardial infarction(AMI). The prevalence of 25(OH)D deficiency and the characteristics associated with it in patients with acute myocardial infarction are unknown. Methods: In this study 25(OH)D was assessed in 314 subjects enrolled in a Sri Jayadeva Institute of Cardiovascular Science and Research(SJICS&R). Patients enrolled from December 1, 2011 to February 28, 2012 had serum samples sent to a centralized laboratory for analysis using the ELECYS assay. Normal 25(OH)D levels are >= 30 ng/ml, and patients with levels < 30 and > 20 ng/ml were classified as insufficient and those with levels <= 20 ng/ml as deficient. Vitamin D and other baseline characteristics were analyzed with T-test and chi-squared test. Results: Of the 314 enrolled patents, 212 (67.5%) were 25(OH)D deficient and 50(16%) were insufficient, for a total of 83.5% of patients with abnormally low 25(OH)D levels. No significant heterogeneity was observed among age or gender sub groups but 25(OH)D deficiency was more commonly seen in those with lower socioeconomic status, lower activity levels, diabetes, hypercholesterolemia(LDL), hypertriglyceridemia and in smokers. Conclusion: Vitamin D deficiency is present in most of the patients with acute myocardial infarction and it is associated with many of its risk factors in our study. PMID- 29450172 TI - Early ambulatory discharge is safe and feasible after transradial coronary interventions. AB - Background: At present, there are no definite criteria for selecting patients eligible for same-day discharge after percutaneous coronary interventions (PCI). With rapid ambulation and reduced vascular complication rates, transradial PCI have many features that favorably reduce costs and hospital stay. This study aimed to demonstrate the possibility of early ambulatory discharge following transradial percutaneous coronary interventions. Methods: 254 consecutive patients undergoing transradial PCI (elective, urgent, and emergent) at our center was observed during hospital stay. Patient demographics, angiographic characteristics, post-procedural complications, and timing of these post procedural events were recorded. Results: A total of 336 lesions were treated among 299 vessels with 277 stents. One hundred fifty-two (45.2%) lesions were Type C. There were 26 chronic total occlusions (CTO). One hundred fifty-five (61%) patients were discharged on the same day after the procedure. 24 complications (12.6%) occurred and were divided into three groups according to occurrence time. 13 (54.2%) occurred within the first 2 h and 11 (45.8%) occurred after the 24-hour period. No complications were observed between the 2nd and 24th hours. Conclusions: Same-day discharge with a 2-hour observation period is safe and feasible after successful transradial PCI in appropriate patients. Although a minor number of complications occurred, these did not occur between the 2nd and 24th hours. Same-day discharge after successful transradial PCI could be an alternative for better utilization of resources. PMID- 29450173 TI - Complications of intracoronary abciximab bolus-only versus standard protocol during percutaneous coronary intervention in acute coronary syndrome. AB - Background: Abciximab reduces major adverse cardiac events in patients with ST elevation myocardial infarction undergoing primary percutaneous coronary intervention (pPCI). Standard protocol is intravenous abciximab bolus during PCI plus abciximab infusion for 12-18 h post pPCI. Intracoronary (IC) abciximab bolus administration results in high local drug concentrations and hence it should have higher antiplatelet effect. In this study, we assess the short-term efficacy and safety of IC compared to IV bolus of abciximab in ACS patients during pPCI. Methods: We compared the clinical outcomes between the IC (n = 56) and standard protocol (n = 170) group of patients. Primary endpoints included bleeding/vascular/ischemic complications and MACE. Results: The two groups were similar with respect to baseline characteristics. IC abciximab bolus only reduced bleeding complications, with no moderate bleed versus 7.2% in standard protocol group (p value 0.04). Ischemic/vascular complications had statistically insignificant difference between the two groups. Conclusion: We found no significant difference between IC abciximab bolus only and standard abciximab therapy in terms of ischemic/vascular complications and MACE. But there was higher risk of moderate bleed in standard therapy group. The IC bolus route of abciximab may be superior to the intravenous route. Prospective randomized trials are warranted to validate these findings. PMID- 29450174 TI - Optical coherence tomography characteristics of in-stent restenosis are different between first and second generation drug eluting stents. AB - Aims: Characterization of neointimal tissue is essential to understand the pathophysiology of in-stent restenosis (ISR) after drug eluting stent (DES) implantation. Using optical coherence tomography (OCT), we compared the morphologic characteristics of ISR between first and second generation DES. Methods and Results: OCT was performed in 66 DES-ISR, defined as > 50% angiographic diameter stenosis within the stented segment. Patients with ISR of first generation sirolimus-eluting stents (SES), paclitaxel eluting stents (PES) and second generation zotarolimus-eluting stents (ZES), everolimus-eluting stents (EES) and biolimus-eluting stents (BES) were enrolled. Quantitative and qualitative ISR tissue analysis was performed at 1-mm intervals along the entire stent, and categorised as homogeneous, heterogeneous and neo-atherosclerosis. The presence of microvessels and peri-strut low intensity area (PSLIA) was determined in all ISR. Neoatherosclerosis was identified by lipid, calcium and thin-cap fibro-atheroma (TCFA) like lesions. We compared the two DES generations at both early (< 1 year) and late (> 1 year) follow-ups.In second generation DES a heterogeneous pattern was prevalent both before and after 1 year (57.1% and 58.6% respectively). Neo-atherosclerosis was more common in the early period in first generation DES (19.4% vs 11.7%, p < 0.01), but after one year was more prevalent in second generation DES (7.0% vs 19.3%, p < 0.01). Similar prevalence of TCFAs was observed in both groups in all comparisons. Conclusions: When ISR restenosis occurs in second generation DES, the current data suggest a different time course and different morphological characteristics from first generation. Future prospective studies should evaluate the relationship between ISR morphology, time course and clinical events. PMID- 29450175 TI - Facilitation of transvenous lead extraction using site-specific delivery of electrosurgical energy. AB - Introduction: Excimer laser energy is often required to extract chronically indwelling pacemaker and defibrillator leads from the vasculature and myocardium. This technique can be associated with vascular and right ventricular (RV) injuries. We sought to develop a safer, more effective method by applying site specific delivery of electrosurgical energy (EE). Methods: Utilizing a polyacrylamide gel model to simulate soft tissue density, active and passive fixation defibrillator and pacemaker leads were implanted and manually extracted with and without EE delivered to the cathode. The amount of force required for complete removal was measured using a force transducer. The procedure was then repeated in an acute pig model to demonstrate proof of safety. Post mortem gross and histologic specimens were collected from the implantation site. Results: In the gel model, the force required for extraction, using manual traction in the active (83.7 g) and passive (74.6 g) fixation ICD leads, was reduced by 37.8% and 33.5%, respectively with EE (both p < 0.01). The force required for extraction, using manual traction in the active (85.2 g) and passive (71.9 g) fixation pacemaker leads, was reduced by 64.4% and 42.6%, respectively with EE (both p < 0.01). In an acute implantation pig model using an active fixation lead, delivery of EE to the cathode (n = 6) reduced the force required to manually extract the lead (140 g +/- 32.5 versus 82 g +/- 14.7, p = 0.03). Post mortem analysis of the RV displayed formation of an epicardial hemorrhagic lesion that was also present after manual traction and EE. There was absence of pericardial effusion, perforation, and ventricular arrhythmia. Conclusions: Site-specific delivery of EE to areas of exposed metal along the lead decreased the force necessary for lead extraction in an in vitro and in vivo model. Further studies are needed to evaluate its application in clinical care. PMID- 29450177 TI - Isolated left coronary ostial occlusion detected by multislice computed tomography. PMID- 29450176 TI - Echocardiographic elastic properties of ascending aorta and their relationship with exercise capacity in patients with non-ischemic dilated cardiomyopathy. AB - Background: : Aortic stiffness, an independent predictor of mortality and cardiovascular events, is common among patients affected by non-ischemic dilated cardiomyopathy (NIDC) and heart failure (HF). Methods: : A total of 55 patients with diagnosis of NIDC (aged 60 +/- 11 years, mean ejection fraction (EF) 35.2% +/- 7.7%) admitted consecutively to our department for mild to moderate HF (NYHA class II-III) underwent an echocardiographic study and cardiopulmonary exercise test (CPX). We evaluated elastic properties of ascending aorta, i.e. aortic stiffness and aortic distensibility (mm Hg- 1), derived from ascending aorta systolic and diastolic diameter (mm/m2) measured 3 cm above the valvular plane through 2D-guided M-mode echocardiography. Results: : Mean aortic stiffness was 15.63 +/- 14.53 and aortic distensibility was 2.61 +/- 2.39 mm Hg- 1. Collected parameters at CPX were peak oxygen consumption (pVO2) (ml/kg/min), anaerobic threshold (AT) and the slope of the relation between minute ventilation (VE) and carbon dioxide production (VCO2). Mean pVO2 was 15.4 +/- 3.9 ml/kg/min, VE/VCO2 ratio at AT was 36.1 +/- 6.1. Functional capacity measured through peak VO2 was found to be directly correlated with aortic distensibility (r = 0.47, p = - 0.0002) and negatively correlated to aortic stiffness index (r = - 0.51, p = - 0.0001). These results were the same at multivariate analysis, corrected by age, hypertension, diabetes mellitus and ejection fraction (respectively r = 0.27, p = 0.008 and r = - 1.75, p = 0.0002). Conclusions: : HF patients due to NIDC elastic properties of ascending aorta, evaluated by echocardiography, are correlated with a reduced functional capacity.

PMID- 29450181 TI - Surgical ablation of atrial fibrillation. AB - Surgical ablation of atrial fibrillation (AF) is currently performed in many major hospitals throughout the world. This paper reviews the development of surgical procedures for AF ablation. It is hoped that the paper can provide a foundation for those involved with ablation of AF to improve patient care. AF is triggered by a rapidly firing focus and could be treated with a localized ablation procedure. A large body of literature has confirmed the safety and efficacy of surgical ablation of AF. New ablation technologies have simplified the surgical treatment of AF and expanded the indications. Generally, more extensive lesion sets have had better long-term outcomes. Despite the tremendous progress that has been made in the development of surgical ablation of AF, many questions remain unanswered. It is anticipated that well designed clinical trials will continue to provide solid evidence to help formulate practice guidelines in the future. PMID- 29450182 TI - Predictive value of neutrophil to lymphocyte ratio for the presence of coronary artery ectasia in patients with aortic aneurysms. AB - Background: Both aortic aneurysms and coronary artery ectasia (CAE) frequently coexist and are associated with more pronounced inflammation. Neutrophil to lymphocyte ratio (NL ratio) is widely used as a marker of inflammation. However, relation between CAE and NL ratio in patients with aortic aneurysms is not fully understood. This study was undertaken to assess relation between CAE and NL ratio in patients with aortic aneurysms. Methods: This study consisted of 93 consecutive patients with aortic aneurysms (AA group) and 79 patients without aortic aneurysms who had angiographically normal coronary arteries as the control group. Moreover, patients with aortic aneurysms were classified into two groups based on the presence of CAE; CAE (+) group (n = 44) and CAE (-) group (n = 49). We compared blood chemical parameters in both groups. Results: In the AA group, 44 patients (47.3%) had CAE. The AA group had a significantly higher NL ratio than the control group (2.93 +/- 1.43 vs. 2.45 +/- 1.05, p = 0.027). Furthermore, the CAE (+) group had a significantly higher NL ratio than the CAE (-) group (3.39 +/- 1.67 vs. 2.52 +/- 1.04, p < 0.01). Multivariate logistic regression analysis revealed that the high NL ratio was an independent predictor for CAE in patients with aortic aneurysms (odds ratio 1.76, 95% confidence interval 1.24 2.69, p = 0.001). Conclusions: Patients with aortic aneurysms had a significantly higher NL ratio than those without aortic aneurysms. Furthermore, the NL ratio might predict the presence of CAE in patients with aortic aneurysms. PMID- 29450183 TI - Trends in percutaneous coronary intervention and angiography in Ireland, 2004 2011: Implications for Ireland and Europe. AB - Background/objectives: To study temporal trends in crude and age standardised rates of cardiac catheterisation and percutaneous coronary intervention (PCI) in Ireland, 2004-2011. Methods: Two data sources were used: a) a survey of publicly and privately funded hospitals with cardiac catheter laboratories to obtain the annual number of procedures performed and b) anonymised data from the Hospital In Patient Enquiry (HIPE) for angiography and PCI in acute publicly funded hospitals; age standardised rates were calculated to study trends over time. Results: From 2004 to 2011 the crude rate of angiography and PCI increased by 47.8% and 35.9% respectively, with rates of 6689 and 1825 per million population in 2011. Following age standardisation, however, PCI activity showed a non significant decrease over time. The PCI to angiography ratio decreased from 30% to 27% and PCI was performed predominantly for stable coronary heart disease (54%) in 2011. Conclusion: Angiography and PCI rates have increased in Ireland but PCI crude and age adjusted rates show divergent trends. While Ireland differs from USA and UK, with a higher proportion of PCI being performed for stable CHD in recent years, little systematic surveillance of cardiological interventions within Europe is available to benchmark improvements in Ireland. PMID- 29450184 TI - Absence of significant aortic regurgitation seven years after closure of patent foramen ovale. AB - Background: It has been suggested that there is an increase in aortic regurgitation (AR) in the short and medium term after percutaneous closure of patent foramen ovale (PFO). The aim of this study is to determine the long-term effect of percutaneous closure of PFO on the prevalence of AR. Methods: Patients with cryptogenic stroke or transient ischemic attack who had undergone percutaneous closure of PFO more than five years before the study were invited to an echocardiographic examination. Results: Out of 83 invited patients, 64 accepted the invitation and were examined with echocardiography. Mild AR was found in one patient (2%), but this was already evident in the patient's echocardiographic result before PFO closure. Trace AR was detected in 11 patients (17%). No case of moderate or severe AR was detected. Patients with AR were more often hypertensive (six out of 12 patients with AR, compared to nine of the 52 without AR, p = 0.025), and the indexed sinus of Valsalva was larger in patients with AR (18.6 mm/m2, SD 1.6, as compared to 17.3 mm/m2, SD 1.6, p = 0.02). Conclusion: In this long-term study with a minimum follow-up of 5.6 years and a mean of 7.1 years, we found negligible levels of AR. Where present, AR was associated with hypertension and mild dilatation of the aortic root, but there was no indication that device closure per se increased the risk of developing AR. PMID- 29450185 TI - The predictive role of electrocardiographic abnormalities in ischemic stroke patients with intravenous thrombolysis. AB - Background/Objectives: The association between electrocardiographic abnormalities and the outcomes in acute ischemic stroke patients after intravenous thrombolysis remains unclear. We sought to assess the predictive value of electrocardiographic abnormalities in stroke patients after thrombolysis. Methods: Consecutive acute stroke patients with thrombolysis from Feb 2008 to Jun 2013 were included. Electrocardiographic abnormalities during hospitalization were retrospectively reviewed. Outcomes were 90-day modified Rankin's Score. Multivariate logistic regression was used to analyze the association of electrocardiographic abnormalities with 90-day outcome. Results: From Feb 2008 to Jun 2013, 95 acute stroke patients (median age of 67 and 64.2% male) with electrocardiographic before/after thrombolysis and 90 day modified Rankin's Score were recruited in our study. Increased age (p = 0.027), higher baseline National Institutes of Health Stroke Scale (p < 0.001) and T-wave changes (p = 0.030) were significantly associated with worse functional outcome. T-wave changes (odds ratio 5.54, 95% confidence interval 1.37-22.37, p = 0.016) were independently associated with unfavorable outcome. Conclusions: T-wave changes can be useful markers to predict the outcome in stroke patients after thrombolysis. PMID- 29450187 TI - Factors associated with longer delays in reperfusion in ST-segment elevation myocardial infarction. AB - Background/objectives: The goal of this paper is to identify the predictors of delay in total ischemia time that would be the focus of improvement efforts in patients with ST-segment elevation myocardial infarction. Methods: Data was collected retrospectively through the patient's clinical records and by direct telephone interview.Total ischemic time was categorized in two classes according to the elapsed time since symptom presentation until restored flow, less than 6 h and 6 h or less. Logistic regression analysis was applied to evaluate the relationship between total ischemic time and a set of variables. Discrimination ability of the model was also assessed, as well as sensitivity and specificity, through ROC curves. Results: Data from 128 patients, 74.22% males and 25.78% females, were analyzed. The average age was approximately 62 years (+/- 13.6).Six variables associated with total ischemia were selected in the final model: the patient age, the level of pain intensity, the region of origin, the socioeconomic status, the activity that the patient was performing at the time of symptoms onset, and the fact that the patient has been transferred from another hospital. Conclusion: The identification of variables associated with the total ischemia time allows the recognition of patients with possibility of worse prognosis, for which should be directed educational efforts and also the identification of variables that can be modified to optimize the therapy. PMID- 29450188 TI - Improved survival rate after myocardial infarction using an inducible cholesterol efflux (iCE) peptide: FAMP. AB - Background: There have been no previous reports that apolipoprotein (apo) A-I mimetic peptide improves survival rate after myocardial infarction (MI). Method and results: Male C57Bl/6J mice were subjected to left coronary artery permanent ligation as a model of MI. We synthesized a novel 24-amino acid apoA-I mimetic peptide-type5 (FAMP5), which potently removes cholesterol via specific ATP binding cassette transporter A1 (ABCA1). FAMP5 was associated with a significantly improved survival rate by protecting against cardiac rupture compared to the control. mRNA levels for eNOS, Gata-4, CTGF and ANP were significantly increased in the hearts of the FAMP5-treated group, while that for MCP-1 decreased. Conclusion: This is the first report that high-density lipoprotein (HDL) therapy with FAMP5 improved the survival rate after MI. PMID- 29450186 TI - Regional variations in baseline characteristics of cardiac rhythm device recipients: The PANORAMA observational cohort study. AB - Background: The PANORAMA study was designed to collect concurrent data on subjects from different worldwide regions implanted with CRM devices. Methods: In this prospective, multi-center study, we analyzed baseline data on 8586 subjects implanted with CRM devices with no additional selection criteria (66% pacemaker (IPG), 16% implantable cardiac defibrillators (ICD), 17% cardiac resynchronization therapy (CRT) and < 1% Internal Loop Recorder) from 156 hospitals across 6 geographical regions between 2005 and 2011. Results: Regardless of the device implanted, subjects from the Middle East and India often had more diabetes than other regions. Eastern and Western Europe had higher rates of atrial fibrillation reported, and men were more likely to smoke than women (46% vs 11%, p < 0.001). Within the CRT cohort there was significant variation in the proportion of males receiving a device, ranging from 55% in India to 83% in Eastern Europe. Conclusions: We provide comprehensive descriptive data on patients receiving CRM devices from a range of geographies that are not typically reported in literature. We found significant variations in clinical characteristics and implant practices. Long term follow-up data will help evaluate if these variations require adjustments to outcome expectations. PMID- 29450189 TI - Effects of transcatheter aortic valve implantation on ascending aorta wall elastic properties: Tissue Doppler imaging and strain Doppler echocardiography study. AB - Background: Aortic elastic properties are determinants of left ventricular function by means of ventriculo-arterial coupling and indicators of cardiovascular risk. Aortic valve stenosis surgical replacement temporary reduces aortic function damaging vasa vasorum, while transcatheter aortic valve implantation (TAVI) does not influence it in the short term. We studied aortic distensibility, stiffness, M-mode strain and tissue strain after 6 and 12 months from TAVI. Methods: We enrolled 15 patients with symptomatic severe aortic stenosis who underwent CoreValve prosthesis (Medtronic, Minneapolis, MN) implantation. Everyone had blood pressure measurement and echocardiography registration before TAVI and after 6 and 12 months. Results: After TAVI NYHA class (p = 0.016), peak and mean aortic valve gradients (p < 0.001 for both) improved. Aortic distensibility increased (p = 0.032 in the first 6 months, p = 0.005 in the second 6 months, and p = 0.003 from baseline to 12 months), as well as stiffness decreased (p = 0.034; 0.090; 0.001), M-mode strain and tissue strain ameliorated (p = 0.041; 0.004; 0.004; and p = 0.013; 0.002; 0.001, respectively), tissue Doppler imaging improved (S' wave: p = 0.289; 0.347; 0.018. E' wave: p = 0.018; 0.113; 0.007. A' wave: p = 0.002; 0.532; 0.001). Moreover, some left ventricular parameters improved at 6 months, such as ejection fraction (from 49 +/- 16 to 57 +/- 11%; p = 0.044) and diastolic interventricular septum thickness (from 14 +/- 2 to 12 +/- 2 mm; p = 0.010). Even systolic pulmonary artery pressure (p = 0.019) and left diastolic dysfunction grade ameliorated (p = 0.042). Conclusions: For the first time we demonstrated that aortic elastic properties improve at 6 and 12 months after TAVI, thus influencing ventriculo arterial coupling and ameliorating left ventricular function. PMID- 29450190 TI - Left atrial emptying fraction predicts limited exercise performance in heart failure patients. AB - Aim: We aimed in this study to assess the role of left atrial (LA), in addition to left ventricular (LV) indices, in predicting exercise capacity in patients with heart failure (HF). Methods: This study included 88 consecutive patients (60 +/- 10 years) with stable HF. LV end-diastolic and end-systolic dimensions, ejection fraction (EF), mitral and tricuspid annulus peak systolic excursion (MAPSE and TAPSE), myocardial velocities (s', e' and a'), LA dimensions, LA volume and LA emptying fraction were measured. A 6-min walking test (6-MWT) distance was performed on the same day of the echocardiographic examination. Results: Patients with limited exercise performance (<= 300 m) were older (p = 0.01), had higher NYHA functional class (p = 0.004), higher LV mass index (p = 0.003), larger LA (p = 0.002), lower LV EF (p = 0.009), larger LV end-systolic dimension (p = 0.007), higher E/A ratio (p = 0.03), reduced septal MAPSE (p < 0.001), larger LA end-systolic volume (p = 0.03), larger LA end-diastolic volume (p = 0.005) and lower LA emptying fraction (p < 0.001) compared with good performance patients. In multivariate analysis, only the LA emptying fraction [0.944 (0.898-0.993), p = 0.025] independently predicted poor exercise performance. An LA emptying fraction < 60% was 68% sensitive and 73% specific (AUC 0.73, p < 0.001) in predicting poor exercise performance. Conclusion: In heart failure patients, the impaired LA emptying function is the best predictor of poor exercise capacity. This finding highlights the need for routine LA size and function monitoring for better optimization of medical therapy in HF.

PMID- 29450192 TI - The Adhesion G-Protein-Coupled Receptor, GPR56/ADGRG1, Inhibits Cell Extracellular Matrix Signaling to Prevent Metastatic Melanoma Growth. AB - Metastatic growth is considered a rate-limiting step in cancer progression, and upregulation of extracellular matrix (ECM) deposition and cell-ECM signaling are major drivers of this process. Mechanisms to reverse ECM upregulation in cancer could potentially facilitate its prevention and treatment but they are poorly understood. We previously reported that the adhesion G-protein-coupled receptor GPR56/ADGRG1 is downregulated in melanoma metastases. Its re-expression inhibited melanoma growth and metastasis and reduced the deposition of fibronectin, a major ECM component. We hypothesize that its effect on fibronectin deposition contributes to its inhibitory role on metastatic growth. To test this, we investigated the function of GPR56 on cell-fibronectin adhesion and its relationship with metastatic growth in melanoma. Our results reveal that GPR56 inhibits melanoma metastatic growth by impeding the expansion of micrometastases to macrometastases. Meanwhile, we present evidence that GPR56 inhibits fibronectin deposition and its downstream signaling, such as phosphorylation of focal adhesion kinase (FAK), during this process. Administration of the FAK inhibitor Y15 perturbed the proliferation of melanoma metastases, supporting a causative link between the cell adhesion defect induced by GPR56 and its inhibition of metastatic growth. Taken together, our results suggest that GPR56 in melanoma metastases inhibits ECM accumulation and adhesion, which contributes to its negative effects on metastatic growth. PMID- 29450193 TI - A Method for Quantification of Epithelium Colonization Capacity by Pathogenic Bacteria. AB - Most bacterial infections initiate at the mucosal epithelium lining the gastrointestinal, respiratory, and urogenital tracts. At these sites, bacterial pathogens must adhere and increase in numbers to effectively breach the outer barrier and invade the host. If the bacterium succeeds in reaching the bloodstream, effective dissemination again requires that bacteria in the blood, reestablish contact to distant endothelium sites and form secondary site foci. The infectious potential of bacteria is therefore closely linked to their ability to adhere to, colonize, and invade epithelial and endothelial surfaces. Measurement of bacterial adhesion to epithelial cells is therefore standard procedure in studies of bacterial virulence. Traditionally, such measurements have been conducted with microtiter plate cell cultures to which bacteria are added, followed by washing procedures and final quantification of retained bacteria by agar plating. This approach is fast and straightforward, but yields only a rough estimate of the adhesive properties of the bacteria upon contact, and little information on the ability of the bacterium to colonize these surfaces under relevant physiological conditions. Here, we present a method in which epithelia/endothelia are simulated by flow chamber-grown human cell layers, and infection is induced by seeding of pathogenic bacteria on these surfaces under conditions that simulate the physiological microenvironment. Quantification of bacterial adhesion and colonization of the cell layers is then performed by in situ time-lapse fluorescence microscopy and automatic detection of bacterial surface coverage. The method is demonstrated in three different infection models, simulating Staphylococcus aureus endothelial infection and Escherichia coli intestinal- and uroepithelial infection. The approach yields valuable information on the fitness of the bacterium to successfully adhere to and colonize epithelial surfaces and can be used to evaluate the influence of specific virulence genes, growth conditions, and antimicrobial treatment on this process. PMID- 29450194 TI - Avoiding Arterial Hypotension in Preterm Neonates (AHIP)-A Single Center Randomised Controlled Study Investigating Simultaneous Near Infrared Spectroscopy Measurements of Cerebral and Peripheral Regional Tissue Oxygenation and Dedicated Interventions. AB - Introduction: Up to 50% of preterm infants admitted to intensive care units require cardiocirculatory support. The aim of the present study was to assess whether simultaneous monitoring of cerebral tissue oxygenation index (cTOI) and peripheral tissue oxygenation index (pTOI) using near-infrared spectroscopy (NIRS) in combination with dedicated intervention guidelines may help avoiding arterial hypotension and catecholamine administration in preterm neonates. Study design: Preterm neonates <37 weeks of gestation were included in a single center randomized controlled study. Blood pressure was measured non-invasively or invasively. In the NIRS group, simultaneous cTOI and pTOI monitoring was used starting within 6 h after birth for 24 h to calculate changes in cTOI/pTOI ratio over time. Depending on these changes, interventions including echocardiography, administration of volume or patent ductus arteriosus treatment were performed. In the control group, only routine monitoring and treatment were performed and NIRS signals were not visible. The primary outcome was burden of hypotension within 48 h after initiation of NIRS monitoring. Results: 49 preterm neonates were included in each group: NIRS group 33.1 (32.0-34.0) (median: 25-75 centile) weeks of gestation and control group 33.4 (32.3-34.3) weeks of gestation. In the NIRS group, echocardiography was performed in 17 preterm neonates due to NIRS measurements, whereby six neonates received further treatment. Percentage of neonates with any hypotensive episode during the 48-h observational period was 32.6% in the NIRS group and 44.9% in the control group (p = 0.214). Burden of hypotension (i.e., %mmHg of mean arterial pressure < gestational age) was 0.0 (0.0-2.1) mmHg h in the NIRS group and 0.4 (0.0-3.3) mmHg h in the control group (p = 0.313), with observed burden of hypotension being low in both groups. No severe adverse reactions were observed. Conclusion: In preterm neonates using simultaneous peripheral and cerebral NIRS measurements for early detection of centralization followed by predefined interventions led to a non-significant reduction in burden of arterial hypotension.

PMID- 29450195 TI - Insecticide-Treated Nets Utilization and Associated Factors among under-5 Years Old Children in Mirab-Abaya District, Gamo-Gofa Zone, Ethiopia. AB - Background: Malaria can be prevented using cost-effective interventions. It can be prevented at large via the use of insecticide-treated mosquito nets (ITNs). The use of ITNs decreases malaria mortality rates by 55% in under-5 years old children in Africa, Ethiopia, realizing the effectiveness, scaling up distribution and utilization of ITNs to cover 100% of children less than 5 years of age. However, little is known about ITNs utilization and factors associated with the utilization in under-5 years old children in the study area yet. The purpose of this study was to assess the level and associated factors of ITNs utilization in under-5 years old children among households with under-5 years old children of Mirab Abaya District, Gamo Gofa Zone, Ethiopia. Methods: A community based cross-sectional study was conducted during August-September, 2016. Six study Kebeles were identified by simple random sampling technique and 398 households with at least one under-5 years old children were selected by random sampling technique using computer generated random numbers from health post family folders. Structured, interviewer questionnaire was administered to mothers or care givers of the children. Data were entered to Epi Info Version 3.5 and analyzed in SPSS version 21 statistical software. Bivariate and multivariate logistic regression analysis was done. P-value <0.05 and odds ratio with 95% confidence interval were used for the determination of associations between dependent and predictor variables. Results were presented in narrations, tables, and graph. Result: Among 398 under-5 years old children assessed, the majority, 362 (91.0%) of them had access to ITN, but only 137 (37.2%) of the child had ITNs utilization during the previous night prior to the survey. Households with age of mothers or caretakers 31-44 years, AOR = 0.03, 95% CI (0.01-0.07) and >=45 years of age; AOR = 0.05, 95% CI (0.01-0.58); households with family size <=5 members, AOR = 11.23, 95% CI (4.31-29.24); and households with sleeping space >=2, AOR = 13.59, 95% CI (4.40-41.93) were found to be significantly associated with under-5 years old children ITNs utilization. Conclusion: Even though, a significant proportions of under-5 years old children had access to ITN, only one-third of the participant child utilized it properly. PMID- 29450196 TI - Recruitment and Lessons Learned from a Community-Based Intervention Program: The Learning Families Project in Hong Kong. AB - Background: Recruitment is central to any research project, and recruitment itself should be well documented and researched. We describe our recruitment efforts for a community-based research project-entitled the Learning Families Project-conducted in Hong Kong. Methods: In collaboration with community stakeholders, residents from a public housing estate were recruited to participate in family programs aimed at enhancing family well-being. Various recruitment strategies were employed including the distribution of 19,200 leaflets, 688 posters, a banner, a kick-off ceremony, 10 promotion activities, 1,000 direct calls, word of mouth, 51 mobile counters, and 10 door-to-door visits. Drawing on field notes, research logs, short questionnaires, and focus group conducted with our community partners and residents, we describe and discuss our recruitment strategies, challenges, and lessons learned. Results: Over a 9-month period, 980 participants were recruited and participated in our study, exceeding our recruitment goal (860 participants). Several observations were made including active recruitment strategies (i.e., door-to-door and mobile counter) being more effective than passive strategies (i.e., posters and leaflets); the importance of raising project awareness to facilitate recruitment; and the challenges encountered (i.e., burn-out and loss of motivation of staff, decreased community capacity in collaborating in research projects). Conclusion: The lessons learned include the importance of engaging Chinese communities, utilizing a positive outreach approach, and setting realistic expectations. Although similar recruitment strategies have been reported the West, a number of cultural differences should be taken into account when working with Chinese population. Further research is needed to examine the effectiveness of tailoring recruitment strategies to various populations. PMID- 29450197 TI - Platelet Counts in Insoluble Platelet-Rich Fibrin Clots: A Direct Method for Accurate Determination. AB - Platelet-rich fibrin (PRF) clots have been used in regenerative dentistry most often, with the assumption that growth factor levels are concentrated in proportion to the platelet concentration. Platelet counts in PRF are generally determined indirectly by platelet counting in other liquid fractions. This study shows a method for direct estimation of platelet counts in PRF. To validate this method by determination of the recovery rate, whole-blood samples were obtained with an anticoagulant from healthy donors, and platelet-rich plasma (PRP) fractions were clotted with CaCl2 by centrifugation and digested with tissue plasminogen activator. Platelet counts were estimated before clotting and after digestion using an automatic hemocytometer. The method was then tested on PRF clots. The quality of platelets was examined by scanning electron microscopy and flow cytometry. In PRP-derived fibrin matrices, the recovery rate of platelets and white blood cells was 91.6 and 74.6%, respectively, after 24 h of digestion. In PRF clots associated with small and large red thrombi, platelet counts were 92.6 and 67.2% of the respective total platelet counts. These findings suggest that our direct method is sufficient for estimating the number of platelets trapped in an insoluble fibrin matrix and for determining that platelets are distributed in PRF clots and red thrombi roughly in proportion to their individual volumes. Therefore, we propose this direct digestion method for more accurate estimation of platelet counts in most types of platelet-enriched fibrin matrix. PMID- 29450198 TI - Parvovirus B19: What Is the Relevance in Transfusion Medicine? AB - Parvovirus B19 (B19V) has been discovered in 1975. The association with a disease was unclear in the first time after the discovery of B19V, but meanwhile, the usually droplet transmitted B19V is known as the infectious agent of the "fifth disease," a rather harmless children's illness. But B19V infects erythrocyte progenitor cells and thus, acute B19V infection in patients with a high erythrocyte turnover may lead to a life-threatening aplastic crisis, and acutely infected pregnant women can transmit B19V to their unborn child, resulting in a hydrops fetalis and fetal death. However, in many adults, B19V infection goes unnoticed and thus many blood donors donate blood despite the infection. The B19V infection does not impair the blood cell counts in healthy blood donors, but after the acute infection with extremely high DNA concentrations exceeding 1010 IU B19V DNA/ml plasma is resolved, B19V DNA persists in the plasma of blood donors at low levels for several years. That way, many consecutive donations that contain B19V DNA can be taken from a single donor, but the majority of blood products from donors with detectable B19V DNA seem not to be infectious for the recipients from several reasons: first, many recipients had undergone a B19V infection in the past and have formed protective antibodies. Second, B19V DNA concentration in the blood product is often too low to infect the recipient. Third, after the acute infection, the presence of B19V DNA in the donor is accompanied by presumably neutralizing antibodies which are protective also for the recipient of his blood products. Thus, transfusion-transmitted (TT-) B19V infections are very rarely reported. Moreover, in most blood donors, B19V DNA concentration is below 1,000 IU/ml plasma, and no TT-B19V infections have been found by such low-viremic donations. Cutoff for an assay for B19V DNA blood donor screening should, therefore, be approximately 1,000 IU/ml plasma, if a general screening of blood donors for single donation blood components is considered at all: for the overwhelming majority of transfusion recipients, B19V infection is not relevant as well as for the blood donors. B19V DNA screening of vulnerable patients after transfusion seems to be a more reasonable approach than general blood donor screening. PMID- 29450199 TI - Transfusion-Transmitted Hepatitis E: NAT Screening of Blood Donations and Infectious Dose. AB - The risk and importance of transfusion-transmitted hepatitis E virus (TT-HEV) infections by contaminated blood products is currently a controversial discussed topic in transfusion medicine. The infectious dose, in particular, remains an unknown quantity. In the present study, we illuminate and review this aspect seen from the viewpoint of a blood donation service with more than 2 years of experience in routine HEV blood donor screening. We systematically review the actual status of presently known cases of TT-HEV infections and available routine NAT-screening assays. The review of the literature revealed a significant variation regarding the infectious dose causing hepatitis E. We also present the outcome of six cases confronted with HEV-contaminated blood products, identified by routine HEV RNA screening of minipools using the highly sensitive RealStar HEV RT-PCR Kit (95% LOD: 4.7 IU/mL). Finally, the distribution of viral RNA in different blood components [plasma, red blood cell concentrate (RBC), platelet concentrates (PC)] was quantified using the first WHO international standard for HEV RNA for NAT-based assays. None of the six patients receiving an HEV contaminated blood product from five different donors (donor 1: RBC, donor 2-5: APC) developed an acute hepatitis E infection, most likely due to low viral load in donor plasma (<100 IU/mL). Of note, the distribution of viral RNA in blood components depends on the plasma content of the component; nonetheless, HEV RNA could be detected in RBCs even when low viral plasma loads of 100-1,000 IU/mL are present. Comprehensive retrospective studies of TT-HEV infection offered further insights into the infectivity of HEV RNA-positive blood products. Minipool HEV NAT screening (96 samples) of blood donations should be adequate as a routine screening assay to identify high viremic donors and will cover at least a large part of viremic phases.

AB - The nutritional compositions and phytochemical properties of eight edible flowers of the ginger family (Zingiberaceae) commonly found in Thailand are reported herein. The plant genera investigated were Zingiber (Ginger, Phlai Dam, Krathue), Hedychium (two morphological filament forms), Curcuma (Ao), Etlingera (Torch ginger), Amomum (Chi Kuk), and Alpinia (Galangal), which are eaten fresh or cooked as ingredients in the preparation of many Thai dishes. The proximate compositions (moisture, ash, fiber, protein, fat, and carbohydrate contents) varied among the different genera. The plants sampled were generally low in fat content (<1%), which contributed as little as 30% of the total caloric energy. Edible plant parts contained substantially high amounts of potassium (max. 737.21 mg/100 g), calcium (max. 140.15 mg/100 g), and iron (~0.32 mg/100 g). Among the tested samples, torch ginger had the highest vitamin C content (1.05 mg/100 g), total phenolic and total flavonoid contents, as well as 2,2-diphenyl-1 picrylhydrazyl activity. On the other hand, the 2,2'-azino-bis (3 ethylbenzothiazoline-6-sulfonic acid) assay suggested that Hedychium species possessed the highest antioxidant activity (~5.38 mg TEAC/g extract). Our results prove that edible plants of the Zingiberaceae family found in Thailand are rich sources of potentially important nutrients. PMID- 29450201 TI - Supporting patients self-managing respiratory health: a qualitative study on the impact of the Breathe Easy voluntary group network. AB - Self-management strategies are designed to improve lung and respiratory health through structured self-management plans with regular practitioner reviews. Strategies have not, however, focused upon how patient support groups and advocacy networks can help with the management of these conditions; therefore, it is unknown what impact they may have on patient self-management. A qualitative study was designed to help understand what impact the British Lung Foundation's Breathe Easy (BE) groups have on patients managing their lung and respiratory conditions. A semistructured telephone interview schedule was developed to study the network. Topics covered included: perceptions about the BE groups; current referrals systems and integration pathways; benefits of attending the BE groups; and integration of the BE groups into the respiratory pathway. Key themes explored included: shared patient experience and peer support; patient self management and self-education; attendance of healthcare professionals; and the impact of integrating BE groups into the respiratory pathway. BE networks were shown to support self-care initiatives for people attending the groups, and members expressed a social and educational benefit. BE networks were working with the local National Health Service to become an integral part of the respiratory pathway, yet there was evidence of resistance from the health service in incorporating the networks.

PMID- 29450203 TI - Real-life experience of ceritinib in crizotinib-pretreated ALK+ advanced non small cell lung cancer patients. AB - Here we report our experience of ceritinib in crizotinib-pretreated patients with anaplastic lymphoma kinase (ALK) positive (ALK+) non-small cell lung cancer (NSCLC) in a French temporary authorisation for use (TAU) study. The French TAU study included crizotinib-pretreated patients with advanced ALK+ or ROS proto oncogene 1 positive (ROS1+) tumours. Patients received oral ceritinib (750 mg.day 1 as a starting dose) and best tumour response (as evaluated by the investigator) and safety were reported every 3 months. A total of 242 TAUs were granted from March 12, 2013 to August 05, 2015. Of the 242 patients, 228 had ALK+ NSCLC and 13 had ROS1+ NSCLC. The median age of ALK+ patients (n=214) was 58.5 years, 51.9% were female, 70.8% had an Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0-1 and 50.0% had brain metastases. Of the 149 efficacy evaluable ALK+ NSCLC patients, 5.4% had a complete response (CR), 47.0% had a partial response (PR) and 22.8% had stable disease (SD). At September 05, 2015, the median duration of ceritinib treatment (n=182) was 3.9 months but 5.5 months for patients (n=71) with a follow-up of >=12 months. Higher objective response rate (ORR) was observed for patients with ECOG PS 0 to 1 (55.0% versus 42.4%) and those receiving prior crizotinib for >5 months (51.6% versus 36.1%). Treatment related adverse events (AEs) were reported in 118 of 208 patients (56.7%), the most common being diarrhoea (22.1%) and hepatic toxicity (19.7%). Ceritinib (750 mg.day-1) demonstrated efficacy similar efficacy to ASCEND-1, ASCEND-2 and phase 3 ASCEND-5 trials with manageable safety in crizotinib-pretreated patients with ALK+ NSCLC. PMID- 29450205 TI - Revision Surgery After Cartilage Repair: Data From the German Cartilage Registry (KnorpelRegister DGOU). AB - Background: Various operative strategies have been introduced to restore the integrity of articular cartilage when injured. The frequency of revision surgery after cartilage regenerative surgery remains incompletely understood. Purpose/Hypothesis: The purpose of this study was to identify the reasons for revision surgery after cartilage regenerative surgery of the knee. We hypothesized that in a large patient cohort, revision rates would differ from those in the current literature. Study Design: Case-control study; Level of evidence, 3. Methods: A total of 2659 complete data sets from the German Cartilage Registry were available for analyses. In brief, baseline data were provided by the attending physician at the time of index surgery. Follow-up data were collected using a web-based questionnaire inquiring whether patients had needed revision surgery during follow-up, which was defined as the endpoint of the present analysis. Results: A total of 88 patients (3.3%) reported the need for revision surgery as early as 12 months postoperatively. Among the most common causes were arthrofibrosis (n = 27) and infection (n = 10). Female patients showed a significantly greater complication rate (4.5%) when compared with male patients (2.6%; P = .0071). The majority of cartilage lesions were located at the medial femoral condyle (40.2%), with a mean defect size of 3.5 +/- 2.1 cm2. Neither the location nor defect size appeared to lead to an increased revision rate, which was greatest after osteochondral autografts (5.2%) and autologous chondrocyte implantation (4.6%). Revision rates did not differ significantly among surgical techniques. Chi-square analysis revealed significant correlations between the number of previous joint surgeries and the need for revision surgery (P = .0203). Multivariate regression analysis further confirmed sex and the number of previous surgeries as variables predicting the need for early revision surgery. Conclusion: The low early revision rates found in this study underline that today's cartilage repair surgeries are mostly safe. Although invasiveness and techniques differ greatly among the procedures, no differences in revision rates were observed. Specific factors such as sex and the number of previous surgeries seem to influence overall revision rates and were identified as relevant risk factors with regard to patient safety. PMID- 29450206 TI - Restriction of Passive Glenohumeral Abduction Combined With Normal Passive External Rotation Is a Diagnostic Feature of Calcific Tendinitis. AB - Background: Passive glenohumeral range of motion may be characteristically limited to specific shoulder pathologies. While pain associated with loss of range of passive external glenohumeral rotation is recognized as a salient feature in adhesive capsulitis, restriction of glenohumeral range of motion in calcific tendinitis of the supraspinatus tendon has never been studied. Hypothesis: On the basis of clinical observation, we hypothesized that calcific tendinitis of the supraspinatus tendon is associated with loss of passive glenohumeral abduction without loss of external rotation. Study Design: Cohort study; Level of evidence, 3. Methods: Ranges of passive glenohumeral rotation and abduction, which are measured with a standardized protocol in our institution, were retrospectively reviewed and compared for patients diagnosed with either adhesive capsulitis or calcific tendinitis of the supraspinatus tendon. A total of 57 patients met the inclusion criteria for the calcific tendinitis, and 77 met the inclusion criteria for the adhesive capsulitis group. Results: When compared with the contralateral, unaffected shoulder, glenohumeral abduction in the calcific tendinitis group was restricted by a median of 10 degrees (interquartile range [IQR], -20 degrees to -5 degrees ) as opposed to glenohumeral external rotation, which was not restricted at all (median, 0 degrees ; IQR, 0 degrees to 0 degrees ). The adhesive capsulitis group showed a median restriction of glenohumeral abduction of 40 degrees (IQR, -50 degrees to -30 degrees ) and a median restriction of passive glenohumeral external rotation of 40 degrees (IQR, -60 degrees to -30 degrees ). Conclusion: Calcific tendinitis of the supraspinatus does not typically cause loss of external rotation but is frequently associated with mild isolated restriction of abduction. This finding can be used to clinically differentiate adhesive capsulitis from calcific tendinitis. PMID- 29450204 TI - PPARs: Key Regulators of Airway Inflammation and Potential Therapeutic Targets in Asthma. AB - Asthma affects approximately 300 million people worldwide, significantly impacting quality of life and healthcare costs. While current therapies are effective in controlling many patients' symptoms, a large number continue to experience exacerbations or treatment-related adverse effects. Alternative therapies are thus urgently needed. Accumulating evidence has shown that the peroxisome proliferator-activated receptor (PPAR) family of nuclear hormone receptors, comprising PPARalpha, PPARbeta/delta, and PPARgamma, is involved in asthma pathogenesis and that ligand-induced activation of these receptors suppresses asthma pathology. PPAR agonists exert their anti-inflammatory effects primarily by suppressing pro-inflammatory mediators and antagonizing the pro inflammatory functions of various cell types relevant to asthma pathophysiology. Experimental findings strongly support the potential clinical benefits of PPAR agonists in the treatment of asthma. We review current literature, highlighting PPARs' key role in asthma pathogenesis and their agonists' therapeutic potential. With additional research and rigorous clinical studies, PPARs may become attractive therapeutic targets in this disease. PMID- 29450207 TI - Fixation of Traumatic Chondral-Only Fragments of the Knee in Pediatric and Adolescent Athletes: A Retrospective Multicenter Report. AB - Background: While traditional biological principles have suggested that fragments consisting of cartilage alone cannot be reaffixed to bone with expectable long term healing, case reports of successful healing after fixation in younger patients indicate that this concept remains incompletely explored. Purpose: To evaluate the presenting features, techniques, healing rates, and clinical and radiological results in a cohort of pediatric and adolescent athletes who underwent fixation of traumatic chondral-only fragments in the knee. Study Design: Case series; Level of evidence, 4. Methods: Patient registries at 2 tertiary care children's hospitals were reviewed to identify patients <=18 years old who underwent fixation of a "chondral-only" fragment in the knee, defined as the inability to visualize the fragment on injury radiographs or discern bone on the articular portion of a fragment intraoperatively. The mechanism of injury, fragment features, fixation technique, and postoperative clinical course, including timing of sports clearance, healing on postoperative magnetic resonance imaging (MRI), and any complications or reoperations, were assessed. Results: Fifteen patients with a median age at surgery of 12.7 years (interquartile range [IQR], 11.7-14.2 years) and median follow-up of 12.0 months (IQR, 6.0-19.2 months) were analyzed. All patients sustained an acute knee injury before surgery. The injured sites, as assessed on MRI, were the patella (n = 6), trochlea (n = 5), and lateral femoral condyle (n = 4). The median fragment surface area was 492.0 mm2 (IQR, 400.0-787.5 mm2). Fixation with bioabsorbable implants was performed in all patients at a median of 1.6 weeks (IQR, 1.0-2.6 weeks) after the injury. One patient (7%) sustained a fall 8 weeks postoperatively, requiring secondary surgery for excision of a dislodged fragment, and 1 patient (7%) underwent unrelated patellar stabilization surgery 3.4 years postoperatively, at which time the fragment was found to be stable. MRI was performed in 9 of 14 patients with retained fragments (median, 12.0 months postoperatively), with 5 patients (56%) showing restoration of the cartilage contour and the resolution of subchondral edema; 2 patients showed thinning but intact cartilage, 1 had cartilage thickening, and 1 had subchondral edema, fissuring, and cystic changes. The median time to return to sports for all 15 patients was 26.0 weeks (IQR, 22.8-40.9 weeks), including 2 patients who required second surgery and returned to sports at 26.1 and 191.1 weeks. Conclusion: Fixation of traumatic chondral-only fragments using bioabsorbable implants may result in successful short-term healing in the majority of pediatric and adolescent athletes. PMID- 29450208 TI - Clinical Outcomes After Microfracture of the Knee: Midterm Follow-up. AB - Background: Microfracture is a single-stage arthroscopic procedure used to treat small- and medium-sized cartilage defects, the clinical results of which have been mixed to date. Purpose: To retrospectively evaluate prospectively collected patient-reported outcomes (PROs) after microfracture as well as to determine patient-related and defect-related factors associated with clinical outcomes and which factors predict the need for additional surgery. Study Design: Case-control study; Level of evidence, 3. Methods: All patients between the ages of 10 and 70 years who underwent microfracture by the senior author for a focal chondral defect of the knee between January 1, 2005, and March 1, 2010, were eligible for study enrollment. Patients were excluded if they underwent concomitant procedures that violated the subchondral bone. Functional outcomes were determined using preoperative and final follow-up PROs, including the Lysholm, International Knee Documentation Committee (IKDC), Knee injury and Osteoarthritis Outcome Score (KOOS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Short Form-12 (SF-12), and overall satisfaction scores. Patient-related factors (sex, age, body mass index [BMI]) and defect-related factors (lesion size, location, concomitant procedures, prior procedures) were analyzed for correlations with outcome scores. All patient-related and defect-related factors were also analyzed as predictors for subsequent surgery. Results: Overall, 101 patients (102 knees; 55 male, 46 female; mean age, 35.87 +/- 12.52 years; mean BMI, 26.3 +/- 5.5 kg/m2; mean defect size, 2.635 +/- 1.805 cm2) were included. Lesion location included 44.90% at the medial femoral condyle, 21.43% at the trochlea, 11.22% at the lateral femoral condyle, 10.20% at multiple sites, 8.16% at the patella, and 4.08% at the tibial plateau. Microfracture was performed alone in 72 of 102 (71%) knees. At a mean follow-up of 5.66 +/- 2.54 years (range, 2-11 years), clinically meaningful and statistically significant improvements were seen in all PROs (P < .05) except the SF-12 mental component score. Patients who had an isolated tibial plateau defect or multiple defects demonstrated reduced improvements in the symptom rate (P = .0237). Patients with a BMI >30 kg/m2 had lower postoperative scores on the KOOS activities of daily living subscale (P = .0261) and poorer WOMAC function and WOMAC pain scores (P = .029 and .0307, respectively). Patient BMI, age, sex, defect location, concomitant procedures, and operative side were not significant predictors for additional surgery. Larger defect size (>3.6 cm2) and prior knee surgery were independent risk factors for additional knee surgery after microfracture. Conclusion: After microfracture, all PROs demonstrated clinically and statistically significant improvements at 5.7 years. Functionally, male patients benefited more from microfracture than female patients. Microfracture of tibial lesions and multisite microfracture provided less benefit than microfracture of isolated femoral defects. Larger lesion size (>3.6 cm2) and prior knee surgery predicted the need for additional knee surgery after microfracture. PMID- 29450209 TI - Creation and Assessment of a Clinical Predictive Calculator and Mortality Associated With Candida krusei Bloodstream Infections. AB - Background: Candida krusei bloodstream infection (CK BSI) is associated with high mortality, but whether this is due to underlying comorbidities in affected patients or the organism itself is unknown. Identifying patient characteristics that are associated with CK BSI is crucial for clinical decision-making and prognosis. Methods: We conducted a retrospective analysis of hospitalized patients with Candida BSI at our institution between 2002 and 2015. Data were collected on demographics, comorbidities, medications, procedures, central lines, vital signs, and laboratory values. Multivariable logistic and Cox regression were used to identify risk factors associated with CK and mortality, respectively. Results: We identified 1873 individual patients who developed Candida BSI within the study period, 59 of whom had CK BSI. CK BSI was predicted by hematologic malignancy, gastric malignancy, neutropenia, and the use of prophylactic azole antifungals, monoclonal antibodies, and beta-lactam/beta lactamase inhibitor combinations. The C-statistic was 0.86 (95% confidence interval, 0.81-0.91). The crude mortality rates were 64.4% for CK BSI and 41.4% for non-CK BSI. Although CK was associated with higher mortality in univariable Cox regression, this relationship was no longer significant with the addition of the following confounders: lymphoma, neutropenia, glucocorticoid use, chronic liver disease, and elevated creatinine. Conclusions: Six patient comorbidities predicted the development of CK BSI with high accuracy. Although patients with CK BSI have higher crude mortality rates than patients with non-CK BSI, this difference is not significant when accounting for other patient characteristics. PMID- 29450210 TI - Sofosbuvir-Based Direct-Acting Antiviral Therapies for HCV in People Receiving Opioid Substitution Therapy: An Analysis of Phase 3 Studies. AB - Background: Hepatitis C virus (HCV) direct-acting antiviral therapy is effective among people receiving opioid substitution therapy (OST), but studies are limited by small numbers of nongenotype 1 (GT1) patients. The aim of this study was to evaluate the treatment completion, adherence, SVR12, and safety of sofosbuvir based therapies in HCV patients receiving and not receiving OST. Methods: Ten phase 3 studies of sofosbuvir-based regimens included ION (ledipasvir/sofosbuvir +/- ribavirin for 8, 12, or 24 weeks in GT1), ASTRAL (sofosbuvir/velpatasvir for 12 weeks in GT1-6), and POLARIS (sofosbuvir/velpatasvir and sofosbuvir/velpatasvir/voxilaprevir in GT1-6). Patients with clinically significant drug use (last 12 months) or noncannabinoids detected at screening were ineligible. Results: Among 4743 patients, 4% (n = 194) were receiving OST (methadone; n = 113; buprenorphine, n = 75; other, n = 6). Compared with those not receiving OST (n = 4549), those receiving OST (n = 194) were younger (mean age, 48 vs 54), more often male (73% vs 61%), GT3 (38% vs 17%), treatment-naive (78% vs 65%), and cirrhotic (36% vs 23%). Among those receiving and not receiving OST, there was no significant difference in treatment completion (97% vs 99%, P = .06), SVR12 (94% vs 97%, P = .06), relapse (0.5% vs 2.1%, P = .19), adverse events (78% vs 77%, P = .79), or serious adverse events (3.6% vs 2.4%, P = .24). There was no difference in SVR12 in patients with cirrhosis (99% vs 95%, P = .25) or those with G3 (95% vs 95%, P = .77) in those receiving OST. Among patients receiving OST, SVR12 was high among those receiving methadone (95%) and buprenorphine (96%). Conclusion: Sofosbuvir-based therapies are effective and safe in patients receiving OST.

PMID- 29450214 TI - Mycobacterium abscessus Complex Infections: A Retrospective Cohort Study. AB - Background: Infections caused by Mycobacterium abscessus group strains are usually resistant to multiple antimicrobials and challenging to treat worldwide. We describe the risk factors, treatment, and clinical outcomes of patients in 2 large academic medical centers in the United States. Methods: A retrospective cohort study of hospitalized adults with a positive culture for M. abscessus in Miami, Florida (January 1, 2011, to December 31, 2014). Demographics, comorbidities, the source of infection, antimicrobial susceptibilities, and clinical outcomes were analyzed. Early treatment failure was defined as death and/or infection relapse characterized either by persistent positive culture for M. abscessus within 12 weeks of treatment initiation and/or lack of radiographic improvement. Results: One hundred eight patients were analyzed. The mean age was 50.81 +/- 21.03 years, 57 (52.8%) were females, and 41 (38%) Hispanics. Eleven (10.2%) had end-stage renal disease, 34 (31.5%) were on immunosuppressive therapy, and 40% had chronic lung disease. Fifty-nine organisms (54.6%) were isolated in respiratory sources, 21 (19.4%) in blood, 10 (9.2%) skin and soft tissue, and 9 (8.3%) intra-abdominal. Antimicrobial susceptibility reports were available for 64 (59.3%) of the patients. Most of the isolates were susceptible to clarithromycin, amikacin, and tigecycline (93.8%, 93.8%, and 89.1%, respectively). None of the isolates were susceptible to trimethoprim/sulfamethoxazole, and only 1 (1.6%) was susceptible to ciprofloxacin. Thirty-six (33.3%) patients early failed treatment; of those, 17 (15.7%) died while hospitalized. On multivariate analysis, risk factors significantly associated with early treatment failure were disseminated infection (odds ratio [OR], 11.79; 95% confidence interval [CI], 1.53-81.69; P = .04), acute kidney injury (OR, 6.55; 95% CI, 2.4-31.25; P = .018), organ transplantation (OR, 2.37; 95% CI, 2.7-23.1; P = .005), immunosuppressive therapy (OR, 2.81; 95% CI, 1.6-21.4; P = .002), intravenous amikacin treatment (OR, 4.1; 95% CI, 0.9-21; P = .04), clarithromycin resistance (OR,79.5; 95% CI, 6.2-3717.1, P < .001), and presence of prosthetic device (OR, 5.43; 95% CI, 1.57-18.81; P = .008). Receiving macrolide treatment was found to be protective against early treatment failure (OR, 0.13; 95% CI, 0.002-1.8; P = .04). Conclusions: Our cohort of 108 M. abscessus complex isolates in Miami, Florida, showed an in-hospital mortality of 15.7%. Most infections were respiratory. Clarithromycin and amikacin were the most likely agents to be susceptible in vitro. Resistance to fluoroquinolone and trimethoprim/sulfamethoxazole was highly common. Macrolide resistance, immunosuppression, and renal disease were significantly associated with early treatment failure.

PMID- 29450216 TI - A Multidisciplinary Delphi Consensus-Based Checklist to Define Clinical Documentation Tools for Both Routine and Research Purposes. AB - Background: To the best of our knowledge, a strategic approach to define the contents of structured clinical documentation tools for both clinical routine patient care and research purposes has not been reported so far, although electronic health record will become more and more structured and detailed in the future. Objective: To achieve an interdisciplinary consensus on a checklist to be considered for the preparation of disease- and situation-specific clinical documentation tools. Methods: A 2-round Delphi consensus-based process was conducted both with 19 physicians of different disciplines and 14 students from Austria, Switzerland, and Germany. Agreement was defined as 80% or more positive votes of the participants. Results: The participants agreed that a working group should be set up for the development of structured disease- or situation-specific documentation tools (97% agreement). The final checklist included 4 recommendations concerning the setup of the working group, 12 content-related recommendations, and 3 general and technical recommendations (mean agreement [standard deviation] = 97.4% [4.0%], ranging from 84.2% to 100.0%). Discussion and Conclusion: In the future, disease- and situation-specific structured documentation tools will provide an important bridge between registries and electronic health records. Clinical documentation tools defined according to this Delphi consensus-based checklist will provide data for registries while serving as high-quality data acquisition tools in routine clinical care. PMID- 29450217 TI - A Cross-Sectional Assessment of Cutaneous Lumbosacral and Coccygeal Physical Examination Findings in a Healthy Newborn Population. AB - Objective. The purpose of this study is to describe the range and frequency of cutaneous lumbosacral and coccygeal findings encountered during the newborn examination in a population of apparently healthy babies, to determine if the prevalence of these findings is associated with race/ethnicity, and to report the frequency of co-occurrence of low-risk cutaneous findings. Methods. Lumbosacral physical findings of 1121 infants were documented on well newborns at least 35 weeks or greater gestational age under the authors' care. The overall frequency of each physical finding was tabulated in addition to determining whether frequencies varied by race/ethnicity. Co-occurrence of the most common physical findings was also examined. Results. Of 1096 infants included in the study, 24.8% had deviated or duplicated gluteal creases, 15.6% had dimples, and 24.7% had lumbosacral and/or coccygeal hairiness. All racial/ethnic groups had double to quadruple the risk of lumbosacral hair when compared with Caucasians. A total of 44.1% of study infants had lumbosacral/coccygeal slate-grey patches, which were least common in Caucasians. Seven infants had coccygeal skin tags, and 14 infants had lumbosacral vascular macules. Thirty-one percent had more than 1 cutaneous lumbosacral finding present, 24.8% had 2 findings, and 6.2% had 3 or more findings. Conclusion. Coccygeal dimples, increased lumbosacral and/or coccygeal hair, deviations and/or duplications of the gluteal crease, and lumbosacral slate grey patches are common in healthy newborns and vary by race/ethnicity. Eleven percent of study infants had 2 or more low-risk cutaneous findings excluding slate-grey patches. Distinction between low-risk and common versus high-risk findings is important when deciding which patients need further evaluation. PMID- 29450218 TI - Attitudes Toward FDA Regulation of Newly Deemed Tobacco Products. AB - Objective: To examine how smokers perceive FDA oversight of e-cigarettes, hookah, and cigars. Methods: Current US smokers (N = 1,520) participating in a randomized clinical trial of pictorial cigarette pack warnings completed a survey that included questions about attitudes toward new FDA regulations covering newly deemed tobacco products (ie, regulation of e-cigarettes, nicotine gels or liquids used in e-cigarettes, hookah, and cigars). Results: Between 47% and 56% of current smokers viewed these new FDA regulations favorably and between 17% - 24% opposed them. Favorable attitudes toward the regulations were more common among smokers with higher quit intentions (adjusted odds ratio (aOR): 1.17, 95% CI: 1.02, 1.33) and more negative beliefs about smokers (aOR: 1.18, 95% CI: 1.05, 1.33). Participants with higher education, higher income, and previous exposure to e-cigarette advertisements had higher odds of expressing positive attitudes toward the new FDA regulations (p < .05). Conclusions: Almost half of current smokers viewed FDA regulation of newly deemed tobacco products favorably. Local and state policy-makers and tobacco control advocates can build on this support to enact and strengthen tobacco control provisions for e-cigarettes, cigars, and hookah.

AB - Bio-additive manufacturing is a promising tool to fabricate porous scaffold structures for expediting the tissue regeneration processes. Unlike the most traditional bulk material objects, the microstructures of tissue and organs are mostly highly anisotropic, heterogeneous, and porous in nature. However, modelling the internal heterogeneity of tissues/organs structures in the traditional CAD environment is difficult and oftentimes inaccurate. Besides, the de facto STL conversion of bio-models introduces loss of information and piles up more errors in each subsequent step (build orientation, slicing, tool-path planning) of the bio-printing process plan. We are proposing a topology based scaffold design methodology to accurately represent the heterogeneous internal architecture of tissues/organs. An image analysis technique is used that digitizes the topology information contained in medical images of tissues/organs. A weighted topology reconstruction algorithm is implemented to represent the heterogeneity with parametric functions. The parametric functions are then used to map the spatial material distribution. The generated information is directly transferred to the 3D bio-printer and heterogeneous porous tissue scaffold structure is manufactured without STL file. The proposed methodology is implemented to verify the effectiveness of the approach and the designed example structure is bio-fabricated with a deposition based bio-additive manufacturing system.

AB - Habits have been studied for decades, but it was not until recent years that experiments began to elucidate the underlying cellular and circuit mechanisms. The latest experiments have been enabled by advances in cell-type specific monitoring and manipulation of activity in large neuronal populations. Here we will review recent efforts to understand the neural substrates underlying habit formation, focusing on rodent studies on corticostriatal circuits. PMID- 29450221 TI - Drinking game participation, gender performance and normalization of intoxication among Nigerian university students. AB - Background: Most research on drinking games (DGs) and the associated risks focuses on Western countries. In the Nigerian context, DGs activity has not attracted scholarly attention but growing media reports indicate that Nigerian youths play DGs, and that a number of gamers have died during or immediately after game-playing. Methods: Drawing on gender performance scripts, we explored the performance of gender through DGs practices and the factors that motivate DGs participation. Thirty-one in-depth interviews were conducted with male and female college students (aged 19-23 years) at a university in south-eastern Nigeria. Results: The participants discussed the popularity of the DGs that students play on this campus, identifying the spaces where each game is played and the motivations for game-playing. Collective, contextual constructions of gender identities through 'Fastest-Drinker' DG were identified, and the participants also performed gender through 'Truth-or-Dare' and 'Endurance' DGs. Men dominated 'First-to-Finish' DGs, which are played at parties and bars, and consumed beer or stout, while women, who mainly played Truth-or-Dare games, drank spirits or sweetened alcoholic beverages. Boredom and fun seeking provoked game-playing among women while adherence to masculinity norms, which engendered the public performance of masculinity and gambling activities, motivated men to play DGs. To avoid 'collective shame', men's friendship groups provided support/care for inebriated game-playing members, but the immediacy of this support/care varied according to DGs type. Conclusion: DGs appear to normalize heavy drinking and the culture of intoxication on this campus. Measures to monitor alcohol sales outlets around campuses and interventions that target students' leisure spaces should be developed. PMID- 29450222 TI - Mood changes after watching pornography on the Internet are linked to tendencies towards Internet-pornography-viewing disorder. AB - Internet-pornography-viewing disorder (IPD) is considered one type of Internet use disorder. For IPD's development, it was assumed theoretically that a dysfunctional use of Internet pornography to cope with depressive mood or stress might be considered to be a risk factor. To address the effect of Internet pornography use on mood, an online study with three measuring points with a sample of male participants was conducted. Participants were investigated regarding their tendencies towards IPD, personal use of Internet pornography, general mood, perceived stress, and their Internet pornography use motivation. Moreover, participants were asked regarding their current mood, sexual arousal, and need to masturbate before and after they watched Internet pornography self determinedly in a private environment. Data showed that tendencies towards IPD were associated negatively with feeling generally good, awake, and calm and were correlated positively with perceived stress in daily life and using Internet pornography for excitation seeking and emotional avoidance. Self-determined use of Internet pornography in their private environment was accompanied by changes in mood and indicators of sexual arousal. Moreover, tendencies towards IPD were negatively related to mood before and after Internet-pornography use as well as an actual increase of good and calm mood. The results showed effects of watching Internet pornography on mood and sexual arousal which can be considered having reinforcing effects for the user. Thus, the results are in line with theoretical assumptions on IPD's development, in which the positive (and negative) reinforcement received by Internet-pornography use is related to cue-reactivity and craving reactions. PMID- 29450223 TI - Hangover resistance in a Canadian University student population. AB - Background: Resistance to alcohol hangover may be a risk factor for alcohol use disorder. Previous research to establish the prevalence of hangover resistance in a drinking population has either not used comparable intoxication levels or has considered hangover resistance over a limited time frame. The purpose of this study was to examine the prevalence of lifetime hangover negative (LHN) drinkers across comparable eBAC values ranging from 0 to 500 mg/dl. Methods: Students at an eastern Canadian university were surveyed about their heaviest drinking episode in the past month and indicated whether they had ever experienced a hangover in their lifetime (LHN) and, if they had, the hangover severity they experienced the next day. eBACs were calculated and the percentage of LHN drinkers was computed at each 10 mg/dl eBAC increment from 0 to 500 mg/dl. Results: Most LHN drinkers (58% female, 71% male) had an eBAC on their heaviest drinking occasion below 80 mg/dl. Above eBACs of 80 mg/dl, 5.8% of female and 5.1% of male drinkers were lifetime hangover negative. Conclusions: The results suggest that only a small percentage of heavy drinkers lay claim to being lifetime hangover negative.

PMID- 29450226 TI - Alcohol reduction in the first trimester is unrelated to smoking, patient or pregnancy characteristics. AB - Introduction: Studies show alcohol-preferring mice reduce their alcohol intake during pregnancy; this study questions if the same is true for humans. The current investigation compares women's pre-pregnancy and first trimester alcohol consumption, examines if women with problem drinking diminish their alcohol intake during pregnancy, and determines if prenatal alcohol reduction is associated with characteristics of pregnancy, patients or smoking. Methods: 126 participants in weeks 1-12 of pregnancy, recruited from Obstetric and Family Practices, completed a survey during their initial prenatal visit including two gender-specific AUDITs (Alcohol Use Disorders Identification Tests) querying current and pre-pregnancy alcohol use. AUDIT-C (AUDIT items 1-3) scores measuring pre-pregnancy and first trimester alcohol consumption were compared, analyzed and tested using general linear model repeated. A p <= 0.05 was accepted as significant. Results: Most participants were multiparous, Caucasian high school graduates experiencing nausea and vomiting. Pre-pregnancy alcohol use was significantly (p = 0.019, Fisher's exact) higher among women seeing obstetricians. Pre-pregnancy AUDIT-C scores (m (mean) = 2.22, sd (standard deviation) = 2.19) were significantly higher (p < 0.001) than first trimester scores (m = 0.143, sd = 0.532). Among 49 with pre-pregnancy AUDIT-C scores >= 3, 45/49 (92%) reduced their alcohol use to zero during the first trimester. Age, race, education, marital status, parity, nausea and vomiting, gestational age and smoking were non-factors in score reduction. Conclusions: Women reported reducing their alcohol consumption during pregnancy, including those screening positive for pre-pregnancy problem drinking. First trimester alcohol reduction cannot be accounted for by smoking, patient or pregnancy characteristics; public health initiatives, psychological factors and hormonal mechanisms may be implicated. PMID- 29450225 TI - Online-specific fear of missing out and Internet-use expectancies contribute to symptoms of Internet-communication disorder. AB - Some of the most frequently used online applications are Facebook, WhatsApp, and Twitter. These applications allow individuals to communicate with other users, to share information or pictures, and to stay in contact with friends all over the world. However, a growing number of users suffer from negative consequences due to their excessive use of these applications, which can be referred to as Internet-communication disorder. The frequent use and easy access of these applications may also trigger the individual's fear of missing out on content when not accessing these applications. Using a sample of 270 participants, a structural equation model was analyzed to investigate the role of psychopathological symptoms and the fear of missing out on expectancies towards Internet-communication applications in the development of symptoms of an Internet communication disorder. The results suggest that psychopathological symptoms predict higher fear of missing out on the individual's Internet-communication applications and higher expectancies to use these applications as a helpful tool to escape from negative feelings. These specific cognitions mediate the effect of psychopathological symptoms on Internet-communication disorder. Our results are in line with the theoretical model by Brand et al. (2016) as they show how Internet-related cognitive bias mediates the relationship between a person's core characteristics (e.g., psychopathological symptoms) and Internet-communication disorder. However, further studies should investigate the role of the fear of missing out as a specific predisposition, as well as specific cognition in the online context. PMID- 29450227 TI - Smoke signals: The decline of brand identity predicts reduced smoking behaviour following the introduction of plain packaging. AB - This study tests a social identity based mechanism for the effectiveness of plain tobacco packaging legislation, introduced in Australia in December 2012, to reduce cigarette smoking. 178 Australian smokers rated their sense of identification with fellow smokers of their brand, positive brand stereotypes, quitting behaviours and intentions, and smoking intensity, both before and seven months after the policy change. Mediation analyses showed that smokers, especially those who initially identified strongly with their brand, experienced a significant decrease in their brand identity following the introduction of plain packaging and this was associated with lower smoking behaviours and increased intentions to quit. The findings provide the first quantitative evidence that brand identities may help maintain smoking behaviour, and suggest the role of social-psychological processes in the effectiveness of public health policy. PMID- 29450228 TI - Ordinary people associate addiction with loss of free will. AB - Introduction: It is widely believed that addiction entails a loss of free will, even though this point is controversial among scholars. There is arguably a downside to this belief, in that addicts who believe they lack the free will to quit an addiction might therefore fail to quit an addiction. Methods: A correlational study tested the relationship between belief in free will and addiction. Follow-up studies tested steps of a potential mechanism: 1) people think drugs undermine free will 2) people believe addiction undermines free will more when doing so serves the self 3) disbelief in free will leads people to perceive various temptations as more addictive. Results: People with lower belief in free will were more likely to have a history of addiction to alcohol and other drugs, and also less likely to have successfully quit alcohol. People believe that drugs undermine free will, and they use this belief to self-servingly attribute less free will to their bad actions than to good ones. Low belief in free will also increases perceptions that things are addictive. Conclusions: Addiction is widely seen as loss of free will. The belief can be used in self serving ways that may undermine people's efforts to quit. PMID- 29450229 TI - Addiction, cigarette smoking, and voluntary control of action: Do cigarette smokers lose their free will? AB - Opinions differ widely as to whether addicts lose the ability to control their behavior and employ free will. This article reviews empirical findings regarding multiple questions relevant to the issue of free will among addicted smokers: Is smoking voluntary behavior? Can people quit smoking? Why don't people quit smoking? Why do smokers relapse when they try to quit? Do addicted smokers suffer from irresistible cravings? Are there some people who cannot quit? Are there conditions that make resistance impossible? Why would they smoke knowing it can kill them? The evidence reviewed here seems most consistent with the view that smokers retain control over their actions but cannot easily stop having frequent desires to smoke. PMID- 29450230 TI - Do addicts have free will? An empirical approach to a vexing question. AB - Introduction: This paper addresses two overlapping questions: Do addicts have the capacity to voluntarily quit drugs? And do individuals knowingly pursue courses of action that they realize are bad for them, such as excessive drug use? Methods: I propose two testable versions of free will. First, the observation that activities differ in the degree to which they are susceptible to the influence of their consequences (e.g., costs and benefits) has proven a useful criterion for classifying behavior as voluntary or involuntary. Thus, we can ask if drug use in addicts is influenced by its consequences. For instance, do laws that promise legal sanctions for drug use reduce drug use in addicts? Second, the philosopher Harry Frankfurt proposed a definition of free will that takes into account desires and self-reflection. I propose that addicts who do not want to desire drugs and successfully stop craving drugs pass his test. Results: Dependence on illicit drugs typically ends after about four to six years. Dependence on cigarettes and alcohol persists for much longer, but most smokers and alcoholics eventually voluntarily quit using. Smokers and heroin addicts can voluntarily regulate their drug cravings as a function of the availability of their drug of choice. They have the capacity to pass Frankfurt's test of free will. Conclusions: Addicts have free will as defined by the capacity to voluntary quit using drugs and to voluntarily regulate their cravings. PMID- 29450232 TI - Predicting early onset of intoxication versus drinking-A population-based prospective study of Norwegian adolescents. AB - Aims: Recent research suggests that early onset of intoxication (EOI) may be of greater importance for a wide range of subsequent adverse outcomes than early drinking experiences without intoxication. However, research on antecedents of EOI is scarce. The present study identifies predictors of EOI and whether they differ from those of early onset of drinking (EOD). Methods: Data was drawn from the prospective Tracking Opportunities and Problems (TOPP) study of Norwegian families (n = 382), which followed up mothers and their children with six data collections from childhood (age 1.5) to adolescence (age 14.5). Self-reports from the adolescents (parenting practices, adolescent's conduct problems and friends' deviant behaviour) and their mothers (adolescent temperament, socio-economic factors and household alcohol problems) were used to identify predictors of EOI and EOD. Findings: A variety of temperamental, socio-economic, and family factors predicted EOI, whereas EOD was predicted of substantially fewer variables. Particularly, when controlling for relevant covariates, low levels of shyness, own conduct problems and having friends with deviant behaviour prospectively predicted EOI, but not EOD. Conclusions: Future research and prevention efforts should take into consideration that EOI and EOD without getting drunk appear to be predicted by different risk factors in childhood and adolescence. PMID- 29450231 TI - Free will in addictive behaviors: A matter of definition. AB - Certain people are at risk for using alcohol or other drugs excessively and for developing problems with their use. Their susceptibility might arise from a variety of factors, including their genetic make-up, brain chemistry, family background, personality and other psychological variables, and environmental and sociocultural variables. Moreover, after substance use has become established, there are additional cognitive-motivational variables (e.g., substance-related attentional bias) that contribute to enacting behaviors consistent with the person's motivation to acquire and use the substance. People who are at such risk are likely to choose to use addictive substances even though doing so entails negative consequences. In the sense of complete freedom from being determined by causal factors, we believe that there is no such thing as free will, but defined as ability to make choices from among multiple options, even though the choices are ultimately governed by natural processes, addicted individuals are free to choose. Although they might appear unable to exercise this kind of free will in decisions about their substance use, addictive behaviors are ultimately always goal-directed and voluntary. Such goal pursuits manifest considerable flexibility. Even some severely addicted individuals can cease their use when the value of continuing the use abruptly declines or when the subjective cost of continuing the use is too great with respect to the incentives in other areas of their lives. Formal treatment strategies (e.g., contingency management, Systematic Motivational Counseling, cognitive training) can also be used to facilitate this reversal. PMID- 29450233 TI - Pharmacogenomics-guided policy in opioid use disorder (OUD) management: An ethnically-diverse case-based approach. AB - Introduction: Opioid use disorder (OUD) is characterized by a problematic pattern of opioid use leading to clinically-significant impairment or distress. Opioid agonist treatment is an integral component of OUD management, and buprenorphine is often utilized in OUD management due to strong clinical evidence for efficacy. However, interindividual genetic differences in buprenorphine metabolism may result in variable treatment response, leaving some patients undertreated and at increased risk for relapse. Clinical pharmacogenomics studies the effect that inherited genetic variations have on drug response. Our objective is to demonstrate the impact of pharmacogenetic testing on OUD management outcomes. Methods: We analyzed a patient who reported discomfort at daily buprenorphine dose of 24 mg, which was a mandated daily maximum by the pharmacy benefits manager. Regular urine screenings were conducted to detect the presence of unauthorized substances, and pharmacogenetic testing was used to determine the appropriate dose of buprenorphine for OUD management. Results: At the 24 mg buprenorphine daily dose, the patient had multiple relapses with unauthorized substances. Pharmacogenetic testing revealed that the patient exhibited a cytochrome P450 3A4 ultrarapid metabolizer phenotype, which necessitated a higher than recommended daily dose of buprenorphine (32 mg) for adequate OUD management. The patient exhibited a reduction in the number of relapses on the pharmacogenetic-based dose recommendation compared to standard dosing. Conclusion: Pharmacogenomic testing as clinical decision support helped to individualize OUD management. Collaboration by key stakeholders is essential to establishing pharmacogenetic testing as standard of care in OUD management. PMID- 29450234 TI - Is the concept of compulsion useful in the explanation or description of addictive behaviour and experience? AB - The concept of compulsion, in which addictive behaviour is said to be carried out against the will, is central to the disease theory of addiction and ubiquitous in modern definitions. The aims of this article are: (i) to describe various meanings of compulsion in the literature; (ii) to compare the part thought to be played by compulsion in addiction with its suggested role in obsessive-compulsive disorder; (iii) to critically examine the place of compulsion in influential neurobiological accounts of addiction; (iv) to summarise the empirical evidence bearing on the usefulness of the compulsion concept, evidence that seems at first sight incompatible with the notion of compulsion. This is followed by a discussion of which possible meanings of compulsion can survive an empirical test and what role they might play in understanding addiction, paying particular attention to a distinction between strong and weak senses of compulsion. A conclusion is that addictive behaviour cannot be considered compulsive at the time it is carried out, though other possible meanings of compulsion as an explanation or description of addictive behaviour and experience are discussed. Among other conclusions, it is suggested that, although in some senses of the term it may seem arbitrary whether or not 'compulsion' should be retained, its use has important consequences for the public understanding of addiction, and is likely to deter people's attempts to overcome their addictions and their chances of success. PMID- 29450235 TI - Vietnamese validation of the short version of Internet Addiction Test. AB - Background and aims: The main goal of the present study was to examine the psychometric properties of a Vietnamese version of the short-version of Internet Addiction Test (s-IAT) and to assess the relationship between s-IAT scores and demographics, health related qualify of life and perceived stress scores in young Vietnamese. Methods: The Vietnamese version of s-IAT was administered to a sample of 589 participants. Exploratory factor and reliability analyses were performed. Regression analysis was used to identify the associated factors. Results: The two factor model of Vietnamese version of s-IAT demonstrated good psychometric properties. The internal consistency of Factor 1 (loss of control/time management) was high (Cronbach's alpha = 0.82) and Factor 2 (craving/social problems) was satisfactory (Cronbach's alpha = 0.75). Findings indicated that 20.9% youths were addicted to the Internet. Regression analysis revealed significant associations between Internet addiction and having problems in self care, lower quality of life and high perceived stress scores. Discussion and conclusions: The Vietnamese version of s-IAT is a valid and reliable instrument to assess IA in Vietnamese population. Due to the high prevalence of IA among Vietnamese youths, IA should be paid attention in future intervention programs. s IAT can be a useful screening tool for IA to promptly inform and treat the IA among Vietnamese youths. PMID- 29450236 TI - Strong preference for mint snus flavor among research participants. AB - Introduction: The Family Smoking Prevention and Tobacco Control Act of 2009 allows the US FDA to regulate tobacco products, including the banning of characterizing flavors, such as fruit and candy, cigarettes. The availability of mint flavored snus may facilitate the use of the product if consumers find it more palatable with respect to taste, odor, pleasantness, and intensity. Methods: This study assessed product evaluation (PES), odor identification, odor intensity, and odor hedonics among 151 smokers enrolled in a clinical trial of snus substitution for cigarettes. Results: Far more participants selected Winterchill (N = 110) than Robust (N = 41), regardless of their menthol cigarette smoking status. Nicotine dependence was higher among those who selected Winterchill (4 vs 3 on Fagerstrom scale, p = 0.017). Those who found Winterchill to be more satisfying, less aversive, and having a more intense, more pleasant odor than Robust were substantially more likely to select Winterchill for their one week trial. Conclusions: Findings indicate that subjective effect measures such as the PES and DEQ are capable of differentiating products in terms of flavor preference, and that smokers express a strong preference for mint flavored snus. PMID- 29450237 TI - The associations among personality, alcohol-related Protective Behavioural Strategies (PBS), alcohol consumption and sexual intercourse in Irish, female college students. AB - Introduction: The study presented one of the first examinations of the associations among personality, alcohol-related protective behavioural strategies (PBS), alcohol consumption, sexual intercourse and sex-related alcohol negative consequences in Irish, female college students (n = 522). Methods: A cross sectional observational design was employed and participants completed the study online. Participants completed measures of personality, alcohol-related PBS, alcohol consumption and sexual intercourse. Hierarchical multiple regression was utilised to access the associations between such measures. Results: From the analyses, it was found that age, frequency of sexual intercourse, frequency of alcohol consumption, level of alcohol consumption and openness were all significantly related to the use of alcohol-related protective behavioural strategies, and in turn, sex-related negative consequences. However, inconsistent findings with other personality dimensions to those of previous research were noted. Conclusions: The findings of this study posited that the use of PBS has a key role to play in the levels of sexual intercourse and alcohol consumption, age and openness, and the associated negative sexual consequences in Irish, female college students. PMID- 29450238 TI - The direct and indirect effect of loneliness on the development of adolescent alcohol use in the United Kingdom. AB - Alcohol use among adolescents in the United Kingdom (UK) remains relatively high compared to those in other European countries. The present study sought to examine both the direct and indirect effect of loneliness on drinking behavior. Participants were school children (mean age 13.5 years at Time 1) participating in a Randomized Controlled Trial in the UK, who completed a battery of questionnaires examining alcohol-use indicators, loneliness, self-efficacy and sensation seeking at Time 1 and at +12 months. Loneliness at Time 1 had a substantive, though largely indirect (i.e., via self-efficacy and sensation seeking covariates), impact on alcohol-related harm at +12 months. Furthermore, Loneliness interacted with gender in the prediction of context of alcohol use, where being female and experiencing loneliness put an individual at a greater risk of unsupervised drinking. Females experiencing loneliness were also 2.9 times as likely to have had a drink in the past 30 days, and around 2.5 times as likely to have ever consumed a full drink, when compared to their male peers. The current results indicate that loneliness is an important but complex factor in adolescent drinking. There are important implications for the development of interventions to prevent underage drinking, not least that it is not appropriate to consider all underage drinkers as socially marginalised. However, for those that are, the self-medication hypothesis is potentially relevant through emotional self-efficacy. PMID- 29450239 TI - Alcohol related mental imagery: The effects of a priming dose in at risk drinkers. AB - Objectives: Drug related mental imagery is proposed to play a central role in addictive behaviour. However, little is known about such cognition or how it is pharmacologically modulated. Here, we test theoretical predictions of the 'elaborated intrusion' theory by comparing neutral with alcohol related mental imagery, and examine the effects of low dose alcohol on phenomenological aspects of this imagery. Methods: Alcohol related and neutral imagery was assessed after at risk drinkers (n = 40) consumed alcohol (0.3 g/kg) or placebo, in a crossover design. Sensory and visuospatial qualities of imagery, along with associated craving, positive affect and 'mind wandering' were assessed. Results: Alcohol related mental imagery was rated as more vivid and sensorially rich, effects that were larger following the priming dose of alcohol. In addition, mind wandering was substantially lower during alcohol versus neutral imagery, especially after alcohol consumption. First person perspective was more prevalent for alcohol imagery after alcohol, although the Drink * Imagery type interaction did not reach statistical significance. However, first person imagery was associated with higher levels of craving during alcohol related imagery. Conclusions: Alcohol related mental imagery differs phenomenologically from neutral imagery on a number of dimensions. Priming with alcohol may enable cognitive elaboration by biasing the output of controlled cognitive processing towards enhanced sensory elaboration and increased attention to alcohol related cognition. These feedforward effects may be involved in focusing cognitive and behavioural resources on alcohol acquisition/consumption through the elaboration and rehearsal of relevant goals and plans. PMID- 29450240 TI - Improving cerebral oxygenation, cognition and autonomic nervous system control of a chronic alcohol abuser through a three-month running program. AB - The abusive use of alcohol has shown to be associated to cerebral damage, impaired cognition, poor autonomic nervous control, impaired cardiovascular health, increased levels of stress and anxiety, depression symptoms and poor quality of life. Aerobic exercise has shown to be an efficient tool to reduce and overcome these issues. In this case report, a patient (forty-four years old, male) under treatment in public psychiatric hospital, classified as having a substance use disorder, underwent a three-month running program. The maximal oxygen consumption increased from 24.2 ml/kg/min to 30.1 ml/kg/min, running time increased from 6 min to 45 min (650%) and distance covered from 765 m to 8700 m (1037.2%). In prefrontal cortex oxygenation, oxyhemoglobin levels improved by 76.1%, deoxyhemoglobin decreased 96.9% and total hemoglobin increased 78.8% during exercise. Reaction time in the cognitive test during rest decreased 23%, and the number of correct answers increased by 266.6%. Parasympathetic cardiac parameters increased in several heart rate variability indices. Thus, we conclude that running exercise performed by an alcoholic patient hospitalized in a psychiatric hospital improves cerebral function, cognition and cardiovascular health. PMID- 29450241 TI - Smartphone addiction, daily interruptions and self-reported productivity. AB - The advent of the smartphone has dramatically altered how we communicate, navigate, work and entertain ourselves. While the advantages of this new technology are clear, constant use may also bring negative consequences, such as a loss of productivity due to interruptions in work life. A link between smartphone overuse and loss of productivity has often been hypothesized, but empirical evidence on this question is scarce. The present study addressed this question by collecting self-report data from N = 262 participants, assessing private and work-related smartphone use, smartphone addiction and self-rated productivity. Our results indicate a moderate relationship between smartphone addiction and a self-reported decrease in productivity due to spending time on the smartphone during work, as well as with the number of work hours lost to smartphone use. Smartphone addiction was also related to a greater amount of leisure time spent on the smartphone and was strongly related to a negative impact of smartphone use on daily non-work related activities. These data support the idea that tendencies towards smartphone addiction and overt checking of the smartphone could result in less productivity both in the workplace and at home. Results are discussed in relation to productivity and technostress. PMID- 29450242 TI - One-year abstinence improves ADHD symptoms among patients with polysubstance use disorder. AB - Introduction: Attention-deficit/hyperactivity disorder (ADHD) is a common comorbid disorder in patients suffering from substance use disorder (SUD). Individuals with co-occurring SUD and ADHD are more likely than SUD patients without ADHD to have developed SUD at a younger age, be polysubstance users, and need inpatient treatment more often. The present study investigates whether individuals with polysubstance use disorder who remain abstinent for a year after entering treatment have a more substantial reduction in ADHD symptoms than those who relapsed and controls. Material and methods: Subjects were SUD patients (N = 115) and healthy controls (N = 34). ADHD symptoms were assessed using the adult ADHD Self-Report Scale (ASRS). Substance use was assessed by self-reports on the Alcohol Use Disorders Identification Test (AUDIT) and the Drug Use Disorders Identification Test (DUDIT). Participants were defined as having relapsed if they had an AUDIT score >= 8 or a DUDIT score >= 2 for women and >= 6 for men. Results: Patients who remained abstinent for one year reported a substantial reduction of ADHD symptoms compared to patients who relapsed and controls. Conclusions: Abstinence alleviates ADHD symptoms among patients with polysubstance use disorder. We suggest that confirmation of an ADHD diagnosis should follow a period of abstinence to avoid identification of false-positive cases. PMID- 29450243 TI - Is exercise addiction in fitness centers a socially accepted behavior? AB - Background: Fitness exercise is popular and associated with improved health and social status. Taken to extremes, however, exercise can become an addiction. One suggested symptom of exercise addiction is "conflicts" with family and friends. However, it may be difficult to recognize excessive exercise patterns if they are accepted and encouraged by relatives. The aim of this study was to explore if fitness exercisers with a high risk of addiction experienced the same level of exercise support as exercisers with a low risk of addiction. Furthermore, we wanted to examine if social support affected the subjective reporting of "conflicts". Method: A total of 577 fitness exercisers completed the Exercise Addiction Inventory (EAI) and two questions asking about "exercise support from family and friends" and "present eating disorder". Results: Exercisers at high risk of exercise addiction reported the same level of support from relatives as those at low risk. Exercisers with high levels of exercise support reported significantly fewer conflicts, even if they were at high risk of addiction. If an eating disorder was present, the level of exercise support was significantly reduced. Conclusion: Exercise addiction might be difficult to identify with the general behavioral addiction symptom "conflict", since exercise is socially accepted even in subjects with high risk of exercise addiction. If an eating disorder is present, the exercise routines seem to be interpreted as socially undesirable. Screening for exercise addiction with the EAI should take into account that fitness exercisers rarely report conflicts, which could result in false negative cases.

AB - Background: Methadone maintenance treatment (MMT) has important protective effects related to reduced illicit opioid use, infectious disease transmission, and overdose mortality. Adherence to MMT has not been examined among homeless people. We measured MMT adherence and reported relevant characteristics among homeless adults experiencing mental illness in Vancouver, British Columbia, Canada. Material and methods: Homeless adults living with mental illness who had received MMT prior to the baseline interview of the Vancouver At Home study (n = 78) were included in analyses. The medication possession ratio (MPR) was used to estimate MMT adherence from retrospective administrative pharmacy and public health insurance data collected across 15 years. Independent sample t tests and one-way ANOVA were used to test for significant differences in MMT MPR by participant characteristics. Results: Mean MMT MPR was 0.47. A large proportion of participants reported blood-borne infectious disease, three or more chronic physical health conditions, and substance use. Being single and never married was associated with significantly lower MMT MPR (0.40 vs. 0.55, p = 0.036), while living with schizophrenia, bipolar disorder, or a mood disorder with psychotic features was associated with significantly higher MMT MPR (0.54 vs. 0.37, p = 0.022). Daily drug use (excluding alcohol) was associated with significantly lower MMT MPR (0.39 vs. 0.54, p = 0.051). Conclusions: The level of adherence to MMT was very low among homeless adults experiencing mental illness. Efforts are needed to improve adherence to MMT as a means of reducing illicit substance use, preventing overdose deaths, and attenuating infectious disease transmission. PMID- 29450245 TI - Video game addiction and psychological distress among expatriate adolescents in Saudi Arabia. AB - Introduction: Few studies have estimated screen time among Arab adolescents, and no studies, to date, have published data on addiction to video games or Internet games among Arab adolescents. This study aimed to assess the prevalence of addiction to video games and its correlation with mental health in a sample of expatriate high school students from the Al-Qassim region of Saudi Arabia. Methods: The survey was conducted in 2016 among 276 students enrolled in ninth through twelfth grades in the International Schools in Buraidah, Al-Qassim. Students who returned signed consent forms from their parents filled out a self administered questionnaire that included validated scales on addiction to video games, general health, and lifestyle. Results: The proportion between the sexes and the schools were roughly equal. Around 32% were overweight or obese, 75% had screen time >= 2 h/day, and 20% slept < 5 h/night. Sixteen per cent (16%) were addicted to video games and 54% had psychological distress. Addiction to video games was strongly associated with psychological distress (OR = 4.1, 95% CI = 1.80, 9.47). Other significant correlates were female gender, higher screen time, and shorter sleep hours. Conclusions: The proportion of students with psychological distress was high. Future studies should investigate other potential correlates of distress such personal traits, family relations, and academic performance. PMID- 29450246 TI - Validation of a Swedish version of the short UPPS-P impulsive behavior scale among young adults. AB - The UPPS-P model of impulsivity proposes that impulsivity comprises five distinct facets-negative urgency, positive urgency, lack of premeditation, lack of perseverance, and sensation seeking. The UPPS-P Impulsive Behavior Scale has been used to measure these facets. The purpose of the current study was to develop and evaluate the psychometric properties of a Swedish version of the 20-item UPPS-P Impulsive Behavior Scale (SUPPS-P). The sample comprised 343 Swedish young adults (Mage = 24.21, SD = 2.01; 27% men, 2% other or undisclosed gender identity) who answered a questionnaire including the SUPPS-P; Depression, Anxiety, and Stress Scale (DASS-21); and questions regarding their alcohol consumption and substance use. Confirmatory factor analysis supported a 5-factor, inter-correlated model, where each subscale of the SUPPS-P constitutes one latent variable. The convergent validity was established by replicating previously found correlations between the different impulsivity facets and depression, anxiety, frequency of alcohol consumption, and substance use. The internal consistency was acceptable for all the SUPPS-P subscales (Cronbach's alpha = 0.65-0.78, McDonald's omega = 0.65-0.79), except lack of perseverance (Cronbach's alpha = 0.60, McDonald's omega = 0.61). Thus, while the Swedish version of the SUPPS-P is suitable for assessing impulsivity in Swedish young adult samples, further research is needed to improve the psychometric properties of the lack of perseverance subscale. PMID- 29450247 TI - The association between financial literacy and Problematic Internet Shopping in a multinational sample. AB - Purpose: To examine the association between financial literacy and Problematic Internet Shopping in adults. Methods: This cross-sectional online survey recruited participants, aged between 18 and 60 years, through an online research facility. The sample consisted of multinational participants from mainly three continents including Europe, North America, and Asia. Problematic Internet Shopping was assessed using the Bergen Shopping Addiction Scale (BSAS). Financial Literacy was measured by the Financial Literacy subscale of the Financial Wellbeing Questionnaire. Multiple linear regression analyses were conducted to elucidate the relationship between the study and outcome variables with adjustment for other potential risk factors. Results: Of the total of 997 respondents with an average age of 30.9 (s.d. = 8.8), 135 (13.8%) could be classified as having a high risk of being Problematic Internet Shoppers. Results from the multiple regression analyses suggested a significant and negative relationship between financial literacy and Problematic Internet Shopping with a regression coefficient of - 0.13, after controlling for the effects of potential risk factors such as age, region of birth, employment, income, shopping frequency, self-regulation and anxiety (t = - 6.42, p < 0.001). Conclusions: The clinical management of PIS should include a financial counselling as a component of the treatment regime. Enhancement of financial literacy in the general population, particularly among young people, will likely have a positive effect on the occurrence of PIS. PMID- 29450248 TI - Metacognitions or distress intolerance: The mediating role in the relationship between emotional dysregulation and problematic internet use. AB - Objective: Given the relevance of problematic Internet use (PIU) to everyday life, its relationship to emotional dysregulation and the importance of metacognitions and distress intolerance in process and intermediaries research, this study examined which of metacognitions and distress intolerance acts as an intermediary between emotional dysregulation and PIU. Methods: In the current study, 413 undergraduate students from the University of Tehran, Iran (202 females; mean age = 20.13) voluntarily completed a questionnaire package which included the Internet Addiction Test (IAT), Difficulties in Emotion Regulation Scale (DERS), Metacognitions Questionnaire 30 (MCQ-30(, and Distress Tolerance Scale (DTS). The data were then analyzed using structural equation modeling by LISREL software. Results: Significant correlations were found between PIU and emotional dysregulation and both distress intolerance and metacognitions (P < 0.001). Structural equation modeling and path analysis results fit well to the data (chi2/df = 1.73; p < 0.001; RMSEA = 0.05; SRMR = 0.04; CFI = 0.97; NFI = 0.95). The results of the mediational model indicated that emotional dysregulation has an indirect impact via metacognition (beta = 0.31; SE = 0.02) and distress tolerance (beta = - 0.60; SE = 0.03) on PIU. The analysis also revealed a significant direct impact of emotional dysregulation on PIU, although this impact is much less than the indirect impact. The variables in this model accounted for 62% of the variance in participants' PIU levels. Conclusion: The results of this study provide evidence for the impact of emotional dysregulation on PIU through metacognitions and distress intolerance. Also, these findings emphasize that distress intolerance has a more significant mediating role than metacognition in the relationship between emotional dysregulation and PIU. PMID- 29450249 TI - Towards an understanding of self-directed language as a mechanism of behavior change: A novel strategy for eliciting client language under laboratory conditions. AB - Introduction: Change talk (CT) and sustain talk (ST) are thought to reflect underlying motivation and be important mechanisms of behavior change (MOBCs). However, greater specificity and experimental rigor is needed to establish CT and ST as MOBCs. Testing the effects of self-directed language under laboratory conditions is one promising avenue. The current study presents a replication and extension of research examining the feasibility for using simulation tasks to elicit self-directed language. Methods: First-year college students (N = 92) responded to the Collegiate Simulated Intoxication Digital Elicitation, a validated task for assessing decision-making in college drinking. Verbal responses elicited via free-response and structured interview formats were coded based on established definitions of CT and ST, with minor modifications to reflect the non-treatment context. Associations between self-directed language and alcohol use at baseline and eight months were examined. Additionally, this study examined whether a contextually-based measure of decision-making, behavioral willingness, mediated relationships between self-directed language and alcohol outcome. Results: Healthy talk and unhealthy talk independently were associated with baseline alcohol use across both elicitation formats. Only healthy talk during the free-response elicitation was associated with alcohol use at follow up; both healthy talk and unhealthy talk during the interview elicitation were associated with 8-month alcohol use. Behavioral willingness significantly mediated the relationship between percent healthy talk and alcohol outcome. Conclusions: Findings support the utility of studying self-directed language under laboratory conditions and suggest that such methods may provide a fruitful strategy to further understand the role of self-directed language as a MOBC. PMID- 29450250 TI - Association between drug use and urban violence: Data from the II Brazilian National Alcohol and Drugs Survey (BNADS). AB - Objective: To investigate the association of alcohol and cocaine use with urban violence (both as victim and as perpetrator) in a representative sample of the Brazilian population. Method: The Second Brazilian Alcohol and Drugs Survey (II BNADS) interviewed 4607 individuals aged 14 years and older from the Brazilian household population including an oversample of 1157 adolescents (14 to 18 years old). The survey gathered information on alcohol, tobacco and illegal substances use as well as on risk factors for abuse and dependence, behaviors associated with the use of substances and the possible consequences, as urban violence indicators. Results: Approximately 9.3% of the Brazilian population has been victim of at least one form of urban violence. This proportion increases to 19.7% among cocaine users and to 18.1% among individuals with alcohol use disorders (AUD). Perpetration of violence was reported by 6.2% of the sample. Cocaine use and AUD increased in almost four times the chances of being an aggressor. Being religious and married decreased the chances of being a victim and/or perpetrador of urban violence. Higher education also decreased the chances of involvement in both victimization or perpetration of violence. Both Parallel Mediation Models considering cocaine use as a predictor of urban violence (victimization or perpetration) were valid and alcohol consumption and depressive symptoms were mediators of this relationship. Conclusions: This study presents relevant data of interest to Brazil as this country is one of the major consumer market of cocaine and also is among the most violent countries worldwide. PMID- 29450251 TI - Online activities, prevalence of Internet addiction and risk factors related to family and school among adolescents in China. AB - Aims: To investigate the online activities, prevalence of Internet Addiction in relation to demographic characteristics and risk factors related to family and school among adolescents. Methods: A total of 6468 10-18 year old adolescents recruited from local schools in Guangzhou, China were selected by adopting multi stage stratified random sampling (female/male: 2886/3582; mean age:13.78 +/- 2.43). Participants completed a structured questionnaire. Results: The overall prevalence of Internet Addiction was 26.50%, with severe addiction being 0.96%. Internet Addiction was higher among males than females (30.6% versus 21.2%). Older grade students reported more Internet addiction rate (chi2 = 431.25, P < 0.001). The five highest-ranked online activities were social networking (94.73%), school work (86.53%), entertainment (82.44%), Internet gaming (73.42%) and shopping online (33.67%). A negative relationship with teachers (OR: 1.35, 95% CI: 1.20-1.53), a negative relationship between two parents (OR: 1.23, 95% CI: 1.18-1.37), and poor academic performance (OR: 1.22, 95% CI: 1.17-1.35), showed the highest relative risks for Internet addiction. Conclusions: Severe Internet Addiction is not common, but mild Internet addiction was reported by more than one fourth of all participants. The rates of Internet Addiction varied by gender, grade, the quality of family relationships and school situation, suggesting these factors should be considered when designing and implementing interventions. PMID- 29450252 TI - Alcohol and tobacco use among methadone maintenance patients in Vietnamese rural mountainside areas. AB - Introduction: The expansion of methadone maintenance treatment (MMT) program requires more data about the factors affecting the effectiveness of treatment, especially behavioral data such as smoking and alcohol use among patients. This study aimed to examine the prevalence of tobacco and alcohol consumption and identify related factors among MMT patients in the Vietnamese rural mountainside. Methods: We interviewed 241 MMT patients in two clinics in Tuyen Quang, a mountainous province in Vietnam. Patients were asked to report the smoking status (current smoker or not), nicotine dependence (by Fagerstrom test for nicotine dependence - FTND) and alcohol use (by using the Alcohol Use Disorders Identification Test - AUDIT-C). EuroQol-5 dimensions-5 levels (EQ-5D-5L) and EQ Visual analogue scale (EQ-VAS) were employed to measure health-related quality of life. Multivariate logistic and Tobit regressions were used to identify the associated factors. Results: The majority of respondents were current smokers (75.7%) and a low proportion were hazardous drinkers (18.3%). People receiving treatment in a rural clinic (OR = 0.45; 95%CI = 0.22-0.92) and had problems in usual activities (OR = 0.20; 95%CI = 0.06-0.70) were less likely to be smokers. Q VAS score (Coef. = 0.03; 95%CI = 0.02-0.05) and having problems in mobility (Coef. = 0.72; 95%CI = 0.03-1.42) was found to be associated with the increase of nicotine dependence. In terms of alcohol drinking, people with other jobs were more likely to drink hazardously compared to unemployed patients (OR = 2.86; 95%CI = 1.20-6.82). Similarly, patients having higher duration of MMT had higher likelihood of being hazardous drinkers (OR = 1.07; 95%CI = 1.01-1.13). Conclusions: This study highlights the low rate of alcohol abusers but a considerably high proportion of current smokers among MMT patients in the rural mountainside area. Alcohol and tobacco counseling programs combined with social and family support also play an essential role in alcohol and tobacco control. In addition, implementing mass community-based behavioral change campaigns to reduce drug addiction-related stigmatization should also be prioritized. PMID- 29450253 TI - Drug, nicotine, and alcohol use among exercisers: Does substance addiction co occur with exercise addiction? AB - Background: Scholastic works suggest that those at risk for exercise addiction are also often addicted to illicit drugs, nicotine, and/or alcohol, but empirical evidence is lacking. Aims: The aim of the present work was to examine the co occurrence of illicit drug, nicotine, and alcohol use frequency (prevalence of users) and severity (level of problem in users) among exercisers classified at three levels of risk for exercise addiction: (i) asymptomatic, (ii) symptomatic, and (iii) at-risk. Methods: A sample of 538 regular exercisers were surveyed via the Qualtrics research platform. They completed the (i) Drug Use Disorder Identification Test, (ii) Fagerstrom Test for Nicotine Dependence, (iii) Alcohol Use Disorder Identification Test, and (iv) Exercise Addition Inventory. Results: A large proportion (n = 59; 10.97%) of the sample was found to be at risk for exercise addiction. The proportion of drug and alcohol users among these participants did not differ from the rest of the sample. However, the incidence of nicotine consumption was lowest among them. The severity of problematic substance use did not differ across the groups. Conclusions: These findings suggest that substance addiction and the risk for exercise addiction are unrelated. In fact, those at risk for exercise addiction exhibited the healthiest profile related to the prevalence of smoking. PMID- 29450254 TI - Correlates of cannabis vape-pen use and knowledge among U.S. college students. AB - Introduction: The proliferation of electronic devices, such as vape-pens, has provided alternative means for cannabis use. Research has found cannabis-vaping (i.e., vape-pen use) is associated with lower perceived risks and higher cannabis use. Knowledge of these products may increase likelihood of subsequent use. As policies for cannabis shift, beliefs that peers and family approve of this substance use (injunctive norms) increase and there has been an increase in vape pen use among young adults (18-35 year olds); however, correlates thereof remain unknown. Young adults often engage in cross-substance use with cannabis and alcohol, making alcohol a potential correlate of cannabis vape-pen use and knowledge. Therefore, we examined alcohol use and other potential correlates of vape-pen use and knowledge among a sample of university students. Methods: This secondary data analysis utilized surveys at multiple colleges in the U.S. (N = 270). Alcohol use, social anxiety, cannabis expectancies, injunctive and descriptive norms and facets of impulsivity were examined as correlates of vape pen use and knowledge using bivariate correlations and logistic regressions. Results: Alcohol use was correlated with cannabis vape-pen use and knowledge. Frequency of cannabis use, peer injunctive norms, and positive expectancies were associated with increased likelihood of vape-pen use. Lack of premeditation, a facet of impulsivity, was associated with cannabis vape-pen knowledge. Conclusions: Given the unknown nature and consequences of cannabis vape-pens, the present findings offer valuable information on correlates of this behavior. Further, correlates of knowledge of vape-pens may point to areas for education and clinical intervention to prevent heavy cannabis vape-pen use. PMID- 29450255 TI - Anterior insula activation during inhibition to smoking cues is associated with ability to maintain tobacco abstinence. AB - Relapse to smoking after initial abstinence is a major clinical challenge with significant public health consequences. At the brain and behavioral level, those who relapse to tobacco smoking have both greater cue-reactivity and lower inhibitory control than those who remain abstinent. Little is known about neural activation during inhibitory control tasks in the presence of drug-related cues. In the current study, tobacco smokers (SMK; n = 22) and non-smoking controls (CON; n = 19) completed a Go/NoGo task involving smoking cues during a functional magnetic resonance imaging (fMRI) scan. Following the scan session, smokers were required to quit smoking, and maintenance of abstinence was evaluated as part of a 12-week smoking cessation trial. We evaluated pre-cessation brain activity during NoGo trials in smokers who were versus were not able to quit smoking. We then compared fMRI and inhibitory control measures between smokers and non smokers. We did not find differences between SMK and CON in performance or activation to smoking or neutral cues. However, compared to SMK who relapsed, SMK who attained biochemically-validated abstinence at the end of the smoking cessation trial had greater neural activation in the anterior insula during NoGo trials specifically with smoking-related cues. Results indicate that within SMK, decreased inhibitory control activation during direct exposure to drug-related stimuli may be a marker of difficulty quitting and relapse vulnerability. PMID- 29450256 TI - Creation and validation of the barriers to alcohol reduction (BAR) scale using classical test theory and item response theory. AB - Those who binge drink are at increased risk for alcohol-related consequences when compared to non-binge drinkers. Research shows individuals may face barriers to reducing their drinking behavior, but few measures exist to assess these barriers. This study created and validated the Barriers to Alcohol Reduction (BAR) scale. Participants were college students (n = 230) who endorsed at least one instance of past-month binge drinking (4+ drinks for women or 5+ drinks for men). Using classical test theory, exploratory structural equation modeling found a two-factor structure of personal/psychosocial barriers and perceived program barriers. The sub-factors, and full scale had reasonable internal consistency (i.e., coefficient omega = 0.78 (personal/psychosocial), 0.82 (program barriers), and 0.83 (full measure)). The BAR also showed evidence for convergent validity with the Brief Young Adult Alcohol Consequences Questionnaire (r = 0.39, p < .001) and discriminant validity with Barriers to Physical Activity (r = -0.02, p = .81). Item Response Theory (IRT) analysis showed the two factors separately met the unidimensionality assumption, and provided further evidence for severity of the items on the two factors. Results suggest that the BAR measure appears reliable and valid for use in an undergraduate student population of binge drinkers. Future studies may want to re-examine this measure in a more diverse sample. PMID- 29450257 TI - Succinylated chitosan derivative has local protective effects on intestinal inflammation. AB - We have previously reported on the anti-inflammatory effects of a water-soluble chitosan derivative, zwitterionic chitosan (ZWC). In the present study, we hypothesized that orally-administered ZWC would provide local anti-inflammatory effects in the intestinal lumen. ZWC indeed showed anti-inflammatory effects in various in-vitro models including peritoneal macrophages, engineered THP1 monocytes, and Caco-2 cells. In Caco-2 cells, ZWC applied before the lipopolysaccharide (LPS) challenge was more effective than when it was applied after it in preventing LPS-induced cell damage. When administered to mice via drinking water as a prophylactic measure, ZWC protected the animals from 2,4,6 trinitrobenzene sulphonic acid (TNBS)-induced colitis, helping them to recover the body weight, restore the gross and histological appearance of the colon, and generate FoxP3+ T cells. In contrast, orally-administered ZWC did not protect the animals from LPS-induced systemic inflammation. These results indicate that orally-administered ZWC reaches the colon with minimal absorption through the upper gastrointestinal tract and provides a local anti-inflammatory effect. PMID- 29450259 TI - Hand-Assisted Laparoscopic Partial Nephrectomy for Large Renal Carcinoma with Succinate Dehydrogenase Deficiency. AB - Background: Germline mutations in succinate dehydrogenase (SDH) are associated with multifocal cancers: pituitary gland tumors, pheochromocytomas, paragangliomas, gastrointestinal stromal tumors, and renal-cell carcinomas (RCCs). SDH-deficient renal-cell carcinoma (SDH-RCC) was first identified in 2004 as an inherited kidney cancer with mutations in the SDH gene. SDH consists of A, B, C, and D units. Mutation in the SDHB gene is the most common mutation in SDH deficient RCCs. Case Presentation: We report a case of a 51-year-old healthy man diagnosed with SDHB germline mutation and RCCs. Positron emission tomography/computed tomography (PET/CT) showed a 12 cm tumor in the upper pole of the left kidney. A hand-assisted laparoscopic partial nephrectomy was performed and the histopathology of the tumor showed SDH-deficient RCC with clear surgical margins. Six months after the initial presentation, the patient had a slightly impaired renal function and was disease-free on PET/CT. Conclusion: Patients with SDH-deficient RCC are at risk of multifocal kidney tumors and should be offered lifelong follow-up. To preserve the renal function, nephron-sparing surgery is the choice of treatment when feasible, regardless of tumor size. PMID- 29450258 TI - The Cannabinoids Delta8THC, CBD, and HU-308 Act via Distinct Receptors to Reduce Corneal Pain and Inflammation. AB - Background and Purpose: Corneal injury can result in dysfunction of corneal nociceptive signaling and corneal sensitization. Activation of the endocannabinoid system has been reported to be analgesic and anti-inflammatory. The purpose of this research was to investigate the antinociceptive and anti inflammatory effects of cannabinoids with reported actions at cannabinoid 1 (CB1R) and cannabinoid 2 (CB2R) receptors and/or noncannabinoid receptors in an experimental model of corneal hyperalgesia. Methods: Corneal hyperalgesia (increased pain response) was generated using chemical cauterization of the corneal epithelium in wild-type (WT) and CB2R knockout (CB2R-/-) mice. Cauterized eyes were treated topically with the phytocannabinoids Delta8 tetrahydrocannabinol (Delta8THC) or cannabidiol (CBD), or the CBD derivative HU 308, in the presence or absence of the CB1R antagonist AM251 (2.0 mg/kg i.p.), or the 5-HT1A receptor antagonist WAY100635 (1 mg/kg i.p.). Behavioral pain responses to a topical capsaicin challenge at 6 h postinjury were quantified from video recordings. Mice were euthanized at 6 and 12 h postcorneal injury for immunohistochemical analysis to quantify corneal neutrophil infiltration. Results: Corneal cauterization resulted in hyperalgesia to capsaicin at 6 h postinjury compared to sham control eyes. Neutrophil infiltration, indicative of inflammation, was apparent at 6 and 12 h postinjury in WT mice. Application of Delta8THC, CBD, and HU-308 reduced the pain score and neutrophil infiltration in WT mice. The antinociceptive and anti-inflammatory actions of Delta8THC, but not CBD, were blocked by the CB1R antagonist AM251, but were still apparent, for both cannabinoids, in CB2R-/- mice. However, the antinociceptive and anti-inflammatory actions of HU-308 were absent in the CB2R-/- mice. The antinociceptive and anti inflammatory effects of CBD were blocked by the 5-HT1A antagonist WAY100635. Conclusion: Topical cannabinoids reduce corneal hyperalgesia and inflammation. The antinociceptive and anti-inflammatory effects of Delta8THC are mediated primarily via CB1R, whereas that of the cannabinoids CBD and HU-308, involve activation of 5-HT1A receptors and CB2Rs, respectively. Cannabinoids could be a novel clinical therapy for corneal pain and inflammation resulting from ocular surface injury. PMID- 29450260 TI - Achieving a 'top-down' change agenda by driving and supporting a collaborative 'bottom-up' process: case study of a large-scale enhanced recovery programme. AB - There is increasing recognition that organisations need to look beyond their boundaries for new innovations. However, the introduction and implementation of best practice that has been developed externally may need different processes of implementation if a successful change process is going to be achieved. Using an enhanced recovery programme as an example, we report a case study that combines the best of a top-down approach with the principles of bottom-up collaborative working to successfully embed a large-scale quality improvement programme that was commissioned to improve the adoption of enhanced recovery in elective surgery. We describe a large-scale change programme that was established, coordinated and driven from within a central 'top' organisation but delivered and owned locally by individual organisations working collaboratively across southeast region of England. We discuss why we believe our methodology of implementing this programme was successful, the important triggers for success and the lessons we learned from the programme. PMID- 29450261 TI - Improving time efficiency gathering equipment in the treatment room. AB - Each junior doctor spends on average 29 hours a year just accessing treatment rooms and approximately 4 working days per year collecting equipment. We identified areas where time efficiency could be improved: accessing treatment room door codes, standardising access to equipment in treatment rooms throughout the hospital, implementing the 'procedure-specific' tray (one tray per procedure which includes all needed equipment in one place) and indexing equipment. Our aim was to reduce the time taken to collect equipment, promote best practice and aid timely medical intervention. We collected data from 24 junior doctors with a Likert scale questionnaire, which confirmed the problem. We then designed an experiment where we timed healthcare professionals accessing treatment rooms with no prior knowledge of the codes and then with codes provided securely on our hospital-issued iPad. We project a time saving of 703 hours (88 working days) at Northampton General Hospital (NGH) over 1 year. We then implemented our prototype 'procedure-specific trays' for common procedures (cannulation, lumbar puncture, catheter). We calculated how much time was saved when collecting equipment using our indexed 'procedure-specific' tray method compared with current practice. Based on our piloted trays, we project to save a total of 802 hours (100 working days) at NGH over 1 year. To finalise our project, we trialled our custom design trays based on our prototype for cannulation and demonstrated a time saving of 97% relative improvement: from 225 s to 7 s. According to these results, once full roll of 'procedure-specific tray' is achieved, the trust will save projected L30 100 per year (based on average junior doctor salary of L20 per hour). PMID- 29450262 TI - Improving access to City and Hackney adult mental health services. AB - City and Hackney Adult Mental Health Referral and Assessment Service (CHAMHRAS) is the single point of entry for all mental health referrals to secondary services, with the exception of perinatal referrals, in the City and Hackney region of London, UK. CHAMHRAS was established in 2013 with the objective of providing a one-stop point of referral which screens urgent and non-urgent referrals of adults aged 18-65 to mental health services. This single point of entry simplifies the referral process to secondary mental health services something service users have requested. It also enables rapid feedback on all referrals taken from general practitioners as well as other sources. The centralised nature of CHAMHRAS has also facilitated the monitoring of waiting times from receipt of referral to first face-to-face assessment across services. It was noted that the waiting time for the majority of patients was exceeding the 28-day target set by local commissioners. Indeed, in December 2014, only 30% of patients were being seen within this time frame. The aim of this quality improvement project has been to decrease the average waiting time from referral to first face-to-face assessment, and concomitantly increase the proportion of patients being assessed within the 28-day target period. The team identified potential sources of delay in the process of handling referrals, from receipt and triage, to forwarding to the relevant secondary service, and have tested change ideas such as the implementation of daily meetings to review referrals and the centralisation of appointment bookings to streamline the processes and minimise delays. The average waiting time from referral to first face-to-face assessment decreased by 34% and the proportion of patients being assessed within 28 days increased accordingly, exceeding 95% in the case of referrals from general practitioners (GP). We have listed changes that we intend to introduce with the aim of bringing waiting times down further. PMID- 29450263 TI - Improving the completeness of acute kidney injury follow-up information in hospital electronic discharge letters. AB - Objectives: Acute kidney injury (AKI) is common in hospitalised patients, often mandates changes to regular medications and can be unresolved at hospital discharge. General practitioners (GPs) require apposite AKI-related information in electronic discharge letters (EDLs). In 2015 NHS England introduced a care quality standard that all EDLs should include four items of information for patients with AKI. We performed a 12-month quality improvement project (QIP) aimed at achieving above 90% compliance with the quality standard. Methods: Hospital-wide episodes of AKI were detected using the nationally approved electronic AKI alerts system. 25 patient AKI episodes were audited per month for 12 months using the electronic patient record. The target compliance rate was staggered at 35%, 65% and 90% for each subsequent 3-month block. Baseline compliance was 22%. Measures taken to improve compliance included email information, grand rounds, ward-level meetings, computer screensavers, nurse support, clinical governance meetings, and face-to-face rapid education. Annotation of AKI within the computer EDL system was progressively enhanced such that in the final quarter the presence of an AKI-alert mandated the user to complete the AKI annotation before the EDL could be signed off. Results: The completion rate improved to 37% in the second quarter, 51% in the third quarter and 92% in the fourth quarter. This change has been sustained in the 14 months since. Conclusions: By the end of the study, omissions relating to AKI information were reduced from 78% to less than 10%, indicating our QIP was highly effective-meeting the quality standard. The single most important factor in improving documentation was to mandate user review of AKI aftercare in patients with electronic AKI alerts. Our study encompassed hospital-wide inpatients, and our results could be replicated at other acute hospitals that have implemented an EDL system connected to an AKI alert system. PMID- 29450264 TI - Improving handover between triage and locality wards in a large mental health trust. AB - Background: South London and Maudsley NHS Foundation Trust is the largest mental health trust in the UK, serving four boroughs in South East London. In 2014, the 'triage ward' system was introduced in three boroughs. Similar to an acute medical admission unit, the triage ward would rapidly assess and treat all new admissions. The patients would either be discharged or admitted to a 'locality ward' for further treatment. Problem: The unforeseen consequences of the 'triage ward' system were duplications and omissions of medical tasks on receiving wards, which affected efficiency and quality of care. This was due to a lack of formal medical handover. We aimed to improve efficiency and patient safety by formalising the junior doctor handover between triage and locality wards, ensuring every patient transferred had a documented handover in their electronic notes. Method: We consulted our colleagues with a survey, ascertaining their views on the current system, the need for a more formalised system and what form that system should take. Using their feedback, we devised a handover template, to be completed for all patients transferred to locality wards. We then rolled the project out to the other two boroughs using the same methodology. Results: A follow-up survey showed improvement in our baseline results and that the majority of transferred patients were formally handed over. Serious incident data showed a decrease in incident rates pre-intervention and post-intervention. The intervention was sustained a year later. The transfer of the intervention to other sites was problematic. Discussion: The project showed the lack of handover was a concern shared by colleagues, and they considered our template a useful way of addressing this. The results suggested that the intervention was sustainable despite frequent rotations of staff. The difficulties in transferring an intervention to new sites are discussed. PMID- 29450265 TI - London Transfer Project: improving handover documentation from long-term care homes to hospital emergency departments. AB - About one-quarter of all long-term care (LTC) residents are transferred to an emergency department (ED) every 6 months in Ontario, Canada. When residents are unable to describe their health issues, ED staff rely on LTC transfer reports to make informed decisions. However, transfer information gaps are common, and may contribute to unnecessary tests, unwanted treatments and longer ED length of stay. London Health Sciences Centre, an academic hospital system in London, Ontario, partnered with 10 LTC homes to improve emergency reporting of their residents' reason for transfer and baseline cognition. After conducting a root cause analysis, 7 of 10 homes implemented a standard minimum set of currently available transfer forms, including a computer-generated summary of resident's most recent interRAI functional assessment. Results were analysed using statistical process control charts and data were posted on a public website (LondonTransferProject.com). The documentation rate of 'reason for transfer' improved from 61% to 84%, and 'baseline cognitive status' improved from 4% to 56% across all 10 homes. These results suggest that transfer communication can be improved by codesigning and implementing solutions with ED and LTC staff, which build upon current reporting practices shared across multiple LTC organisations. PMID- 29450266 TI - Collaborative approach to reducing cardiac arrests in an acute medical unit. AB - Cardiac arrests are often preceded by a period of physiological deterioration. Preventing potentially avoidable cardiac arrests therefore depends on reliable recognition of, and response to, those deteriorations. Our hospital's acute medical unit had one of the highest rates of cardiac arrest in our organisation at baseline. The aim was to reduce our unit's cardiac arrest rate by over 50%. Pareto chart analysis identified unreliable processes in the recognition and response to deteriorating patients. Process mapping exercises were performed, then the model for improvement and rapid cycle tests of change were used to develop standardised processes for clinical observations, recognising deteriorating patients and responding to hypoxia. Multidisciplinary learning from what went well, incorporating resilience engineering principles, helped to identify good practice and then test ways of making good practice happen more reliably. Learning from success also addressed some of the psychological barriers to change by encouraging pride in work and a positive focus within our unit. The cardiac arrest rate reduced from 4.3/1000 (October 2014 to February 2016) to 1.1/1000 (March 2016 to end of 2016), associated with improved reliability of the following process measures: reliability of clinical observations, documentation of target oxygen saturations, identification of hypoxia and completion of structured response to hypoxia. This study is an example of a multidisciplinary team engaging in quality improvement, identifying their own local problems and testing their solutions scientifically. Learning from what went well had a positive impact on the project, and the team plans to spread the successful interventions across the organisation. PMID- 29450267 TI - Fall risk and prevention agreement: engaging patients and families with a partnership for patient safety. AB - Significance and background: Falls are multifactorial in medical oncology units and are potentiated by an older adult's response to anxiolytics, opiates and chemotherapy protocols. In addition, the oncology patient is at an increased risk for injury from a fall due to coagulopathy, thrombocytopenia and advanced age. At our National Cancer Institute-designated inpatient cancer treatment centre located in the southeastern USA, 40% of the total discharges are over the age of 65. As part of a comprehensive fall prevention programme, bimonthly individual fall reports have been presented with the Chief Nursing Officer (CNO), nursing directors, nurse managers, physical therapists and front-line providers in attendance. As a result of these case discussions, in some cases, safety recommendations have not been followed by patients and families and identified as an implication in individual falls. Impulsive behaviour was acknowledged only after a fall occurred. A medical oncology unit was targeted for this initiative due to a prolonged length of stay. This patient population receives chemotherapeutic interventions, management of oncological treatment consequences and cancer progression care. Purpose: The aim of this project was to explore if initiation of a Fall Prevention Agreement between the nursing team and older adults being admitted to medical oncology units would reduce the incidence of falls and the incidence of falls with injury. Interventional methods: In order to promote patient and family participation in the fall reduction and safety plan, the Fall Risk and Prevention Agreement was introduced upon admission. Using the Morse Fall Scoring system, patient's risk for fall was communicated on the Fall Risk and Prevention Agreement. Besides admission, patients were reassessed based on change of status, transfer or after a fall occurs. Evaluation/findings: Fall and fall injuries rates were compared two-quarters prior to implementation of the fall agreement and eight-quarters post implementation. Falls and fall injuries on the medical oncology unit had an overall reduction of 37% and 58.6%, respectively. Discussion/implications: A robust fall prevention standard does not ensure care team participation in all elements to reduce fall occurrence. Historically, the Fall Risk and Prevention Agreement had not been initiated on admission. Incorporating patients and families in discussions related to fall risk and prevention is consistent with collaborative communication. The Joint Commission and the Centers for Medicare and Medicaid Services in 2002 encouraged patients and family participation in the acute care experience to promote safety. The medical oncology patient in many cases on admission is identified as 'moderate' risk for fall. It is during the course of treatment and an extended length of stay that deconditioning and treatment side effects result in a fall. This patient population often overestimates their abilities and functional status.Engagement with patients and families during the admission process will hopefully communicate the need for a collaborative effort for fall prevention during the hospitalisation. Although this project is limited in data, integrating patients and families into care planning may have a significant impact in reducing falls in the 'moderate' risk patient. Additional studies including a multivariate analysis are needed to determine whether supporting evidence links fall reduction to the presence and use of a patient and family agreement. PMID- 29450268 TI - Patient-centred improvement to repeat prescribing using the Always Event concept. AB - Repeat prescriptions are prescriptions issued to a patient for a second or subsequent time without requiring a consultation with a doctor. Repeat prescribing is common and an efficient system is necessary to deliver a high quality service. Always Events can be used to drive patient-centred improvements in healthcare delivery. Our aim was to use the Always Event concept to improve our repeat prescribing system. This quality improvement project was carried out in a deprived, inner-city general practice setting in Glasgow, UK. 51 patients taking repeat medications completed short questionnaires, and the Always Event 'Repeat prescriptions should be ready and available to collect' was generated. We used the Plan-Do-Study-Act cycles to elucidate how our system could be improved and check if our intervention was effective. Over a 3-day period in July 2016, 269 out of 292 prescriptions (92.1%) were ready. We mapped out the repeat prescribing process and discovered that sometimes reception staff graded a request as inappropriate, for example, requested too early, and these requests were therefore not processed. Patients would then attend to collect a prescription that was not there. This was both inconvenient for the patient and time-consuming for the reception staff to investigate the reason. Our system was changed so that any request that was not being processed was recorded and the patient informed. In September 260 out of 267 (97.4%) prescriptions were ready, in November 350 out of 364 (96.2%), and in February 2017 314 out of 323 (97.2%) were ready. In conclusion, the Always Event approach allowed us to elicit important feedback from patients to identify a weakness in our repeat prescribing system, which was simple to rectify and led to an improved, more efficient service. PMID- 29450269 TI - Improving the ability to review preoperative radiographs intraoperatively in trauma and orthopaedic theatres at Lancashire teaching hospitals. AB - Background: The ability to review preoperative radiographs during trauma and orthopaedic surgery is essential for the surgeon to provide optimum treatment to the patient. However, due to current information technology (IT) systems, screen savers frequently interrupt the ability to review images and theatre staff are not routinely available to deactivate the screen-saver. This prolongs theatre time for the patient and affects the quality of care provided. The aim of this quality improvement project was to improve the availability of radiographs for the surgeon to review intraoperatively. Method/results: Data were collected from all trauma and orthopaedic theatres at two hospital sites covering all subspecialties and including emergency and elective cases. Baseline measurements showed that the frequency of preoperative radiographs not interrupted during an operation was 0% (0/50). Following this the Trust's IT systems were improved to prevent activation of the screen-saver on the theatre computers using the generic theatre login details. After the first-cycle intervention, data were collected showing 52% (14/27) of preoperative radiographs were not interrupted by a screen saver. The cause for this result being less than expected was investigated and found to be due to an alternative computer login being used on the theatre computers at one of the hospital sites. Education of theatre staff was then undertaken to ensure the correct theatre login was used and notices to remind staff placed on the theatre computers. After the second-cycle intervention, data were collected showing that 100% (26/26) of preoperative radiographs were not interrupted during operative time allowing the surgeon to review images when required. Conclusion/implications: This quality improvement project has made changes to theatre IT systems and practices of theatre staff which has resulted in a significant improvement in the ability for the operating surgeon to review preoperative radiographs intraoperatively. PMID- 29450270 TI - A local quality initiative to improve follow-up times for patients with heart failure. AB - Introduction Heart failure is the most common cause of hospital admission in patients >65 years and around 50% of patients will be readmitted within 6 months. Inability to achieve timely outpatient follow-up may contribute to the high rates of avoidable rehospitalisation for this group of patients. Canadian guidelines recommend patients with heart failure should be seen within 14 days of discharge. Methods An audit demonstrated that less than half of advanced heart failure patients were being followed up within 14 days. In an effort to improve postdischarge follow-up in our heart function clinic, we used process mapping and applied a series of iterative changes to the appointment booking system using Plan-Do-Study-Act cycles to reduce waste and standardise. Results The primary outcome measure, tracked over a period of 20 months, was percentage of patients booked within 14 days. At baseline, 37% of patients were seen within 14 days. After our series of interventions related to streamlining and standardising the appointment booking process, 77% of patients were seen within 14 days and 100% of patients were seen within 21 days. Conclusion The changes made to the appointment booking process were reproducible, sustainable, effective and required no additional resources or funding. PMID- 29450271 TI - Improving monitoring of diabetic complications in home care patients. AB - Introduction: Uncontrolled diabetes mellitus can lead to microvascular and macrovascular complications. Early detection of complications is necessary to prevent end-organ damage and reduce diabetes-related morbidity. In Qatar, the Home Health Care Services of Hamad Medical Corporation caters to about 1000 patients, who solely depend on home healthcare physicians for primary care coordination, which includes management of chronic medical illnesses such as diabetes, stroke, hypertension and anaemia. Due to physician shortage, different physicians new to home care cover patients on different days. This leads to inconsistency of monitoring for many chronic conditions including diabetes and its complications. In this context, we conducted a quality improvement project to improve compliance to monitoring of diabetes complications in Home Healthcare Services by the implementation of a checklist. Methods: We initially collected baseline data on monitoring of diabetes complications by chart review. Quality improvement principles and methods were employed to develop a checklist-based intervention to improve screening of diabetes complications by healthcare staff. Results: Following the intervention, checklist completion rate improved from 0% 36% in 3 months to 63% in 2 years. The healthcare staff's knowledge of monitoring for diabetes complications improved significantly across all monitored parameters. Furthermore, the percentage of patients being monitored for diabetes complications (ie, outcomes) also improved substantially. Monitoring for proteinuria and diabetic retinopathy improved from 10% and 17% at baseline to 85% and 74% 2 years postintervention, respectively. Conclusion: In conclusion, quality improvement methods were successfully used to improve monitoring of diabetes complications according to international guidelines in a very vulnerable population. PMID- 29450272 TI - Evaluation of a newly introduced tonsillectomy operation record for the analysis of regional post-tonsillectomy bleed data: a quality improvement project at the London North West Healthcare NHS Trust. AB - The primary objective of this audit and quality improvement project was to retrospectively analyse regional post-tonsillectomy haemorrhage data as per national recommendations. However, this process highlighted the need for high quality routinely collected data; something that was not always available via retrospective audit and thus does not enable formal aetiological factor analyses. We therefore created further secondary objectives to facilitate our primary audit objective. These secondary objectives were (1) to introduce a standardised tonsillectomy operation proforma to improve completeness and quality of routinely collected data and (2) to evaluate and validate proforma use and usefulness in improving using routine data collection to help with a repeated audit of post tonsillectomy haemorrhages with the eventual aim to help improve operative outcomes by identifying potential associated factors. The retrospective audit component, the prospective audit and the quality improvement component were all carried out at the Northwick Park Hospital and Central Middlesex Hospital (London North West Healthcare NHS Trust). First, 642 tonsillectomy records (2012-2014) were retrospectively reviewed. Free-text operative documentation and, where possible, potential factors associated with post-tonsillectomy haemorrhages were analysed. In addition, completeness of data available before and after the introduction of (A) a new paper-based and (B) electronic surgical record proforma was reviewed (2014-2015). Over a 2-year period, 62 of the 642 (9.7%) audited tonsillectomy patients had a post-tonsillectomy haemorrhage, and 19 of these (2.9%) had to return to theatre for surgical arrest of the haemorrhage. Bipolar diathermy was the most commonly used technique. During this period, data available from routine operative documentation in the surgical operation notes were variable and thus did not allow identification of potential factors associated with post-tonsillectomy haemorrhage. The completeness and quality of data significantly improved after the introduction of a standardised paper-based proforma with sections for required details based on known risk factors for post tonsillectomy haemorrhage and required operative details. Quality and completeness of data was further improved after the introduction of an electronic version. This electronic proforma will allow prospective spiral auditing results, early identification of raised bleeding rate, and provide individual surgeon audit results. PMID- 29450273 TI - Effectiveness of a multi-component quality improvement intervention on rates of hyperglycaemia. AB - Purpose: To evaluate the effectiveness of a multifaceted, hospital-wide glycaemic control quality improvement programme. Methods: The quality improvement intervention comprised three components, derived through root cause analysis: standardising and simplifying care (including evidence-based order sets), increasing visibility (through provider access to clinical data and direct feedback) and educational outreach (directed at the entire institution). Effectiveness was determined at a single urban acute care hospital through time series analysis with statistical process control charts. Primary outcomes included rate of hyperglycaemia and rate of hypoglycaemia. Results: The study included 70 992 hospital admissions for 50 404 patients, with 3 35 645 patient days. The hyperglycaemia ratio decreased 25.2% from 14.1% to 10.5% (95% CI 3.3 to 3.9 percentage points, p<0.001). The ratio of patient days with highly elevated blood glucose (>299 mg/dL) decreased 31.8% from 4.8% to 3.3% (95% CI 1.4 to 1.7 percentage points, p<0.001). Hypoglycaemia ratio decreased from 5.2% to 4.6% (95% CI 0.27 to 0.89 percentage points, p<0.001) in patients with diabetes, but increased in patients without diabetes from 1.2% to 1.7% (95% CI 0.46 to 0.70 percentage points, p<0.001). Conclusions: We demonstrate improved hospital-wide glycaemic control after a multifaceted quality improvement intervention in the context of strong institutional commitment, national mentorship and Lean management. PMID- 29450274 TI - Strengthening value-based medication management in a free clinic for the uninsured: Quality interventions aimed at reducing costs and enhancing adherence. AB - Skyrocketing costs of prescription medications in the USA pose a significant threat to the financial viability of safety net clinics that opt to supply medications at low to no out-of-pocket costs to patients. At the East Harlem Health Outreach Partnership clinic of the Icahn School of Medicine at Mount Sinai, a physician-directed student-run comprehensive primary care clinic for uninsured adults of East Harlem, expenditures on pharmaceuticals represent nearly two-thirds of annual costs. The practice of minimising costs while maintaining quality, referred to as high-value care, represents a critical cost-saving opportunity for safety net clinics as well as for more economical healthcare in general. In this paper, we discuss a series of quality improvement initiatives aimed at reducing pharmacy-related expenditures through two distinct yet related mechanisms: (A) promoting value-conscious prescribing by providers and (B) improving patient adherence to medication regimens. Interventions aimed at promoting value-conscious prescribing behaviour included blacklisting a costly medication on our clinic's formulary and adding a decision tree in our mobile clinician reference application to promote value-conscious prescribing. Interventions targeted to improving patient adherence involved an automated text messaging system with English and Spanish refill reminders to encourage timely pick-up of medication refills. As a result of these processes, the free clinic experienced a 7.3%, or $3768, reduction in annual pharmacy costs. Additionally, medication adherence in patients with diabetes on oral antihyperglycaemic medications increased from 55% to 67%. Simultaneous patient-based and provider based interventions may be broadly applicable to addressing rising pharmacy costs in healthcare across the USA. PMID- 29450275 TI - Improving cardiac operating room to intensive care unit handover using a standardised handover process. AB - Handovers from the cardiovascular operating room (CVOR) to the cardiovascular intensive care unit (CVICU) are complex processes involving the transfer of information, equipment and responsibility, at a time when the patient is most vulnerable. This transfer is typically variable in structure, content and execution. This variability can lead to the omission and miscommunication of critical information leading to patient harm. We set out to improve the quality of patient handover from the CVOR to the CVICU by introducing a standardised handover protocol. This study is an interventional time-series study over a 4 month period at an adult cardiac surgery centre. A standardised handover protocol was developed using quality improvement methodologies. The protocol included a handover content checklist and introduction of a formal 'sterile cockpit' timeout. Implementation of the protocol was refined using monthly iterative Plan Do-Study-Act. The primary outcome was the quality of handovers, measured by a Handover Score, comprising handover content, teamwork and patient care planning indicators. Secondary outcomes included handover duration, adherence to the standardised handover protocol and handover team satisfaction surveys. 37 handovers were observed (6 pre intervention and 31 post intervention). The mean handover score increased from 6.5 to 14.0 (maximum 18 points). Specific improvements included fewer handover interruptions and more frequent postoperative patient care planning. Average handover duration increased slightly from 2:40 to 2:57 min. Caregivers noted improvements in teamwork, content received and patient care planning. The majority (>95%) agreed that the intervention was a valuable addition to the CVOR to CVICU handover process. Implementation of a standardised handover protocol for postcardiac surgery patients was associated with fewer interruptions during handover, more reliable transfer of critical content and improved patient care planning. PMID- 29450276 TI - Nurse-managed transitional beds as a method of increasing geographic placement of an academic inpatient service. AB - Geographic placement of patients in hospitals has long been valued to bring together all healthcare members as a team focused on high-quality patient-centred care. This goal can be particularly challenging for physicians whose patients are often scattered across various hospital units. The inpatient medicine service for the Palmetto Health-University of South Carolina Internal Medicine Residency Program began attempting geographic placement when a model for team-based care was adopted in 2015, but despite various process improvements we found it very difficult to maintain a high census of our patients on the unit. We eventually came up with an innovative solution to the problem that incorporated the use of transition beds-beds dedicated for patients moving onto or out of the unit in order to make it easier for the unit to control patient flow. We saw an immediate increase in our average census from ~8 to ~15 patients as well as a major shift of the median admission time to 3.5 hours earlier in the day. Unfortunately, it was an added burden to our already stressed charge nurses, and when the pilot ended we were forced to end the use of the transition beds. Despite our challenges, we applied valuable lessons learnt that have helped us in other improvement projects, and overall we did successfully demonstrate that transition beds are a viable option for an inpatient medical unit to improve geographic placement of patients while optimising patient flow. PMID- 29450277 TI - A quality improvement project to improve the Medicare and Medicaid Services (CMS) sepsis bundle compliance rate in a large healthcare system. AB - Sepsis is a leading cause of mortality and morbidity in hospitalised patients. The Centers for Medicare and Medicaid Services (CMS) mandated that US hospitals report sepsis bundle compliance rate as a quality process measure in October 2015. The specific aim of our study was to improve the CMS sepsis bundle compliance rate from 30% to 40% across 20 acute care hospitals in our healthcare system within 1 year. The study included all adult inpatients with sepsis sampled according to CMS specifications from October 2015 to September 2016. The CMS sepsis bundle compliance rate was tracked monthly using statistical process control charting. A baseline rate of 28.5% with 99% control limits was established. We implemented multiple interventions including computerised decision support systems (CDSSs) to increase compliance with the most commonly missing bundle elements. Compliance reached 42% (99% statistical process control limits 18.4%-38.6%) as CDSS was implemented system-wide, but this improvement was not sustained after CMS changed specifications of the outcome measure. Difficulties encountered elucidate shortcomings of our study methodology and of the CMS sepsis bundle compliance rate as a quality process measure. PMID- 29450278 TI - Improving referral to psychological support unit at Saudi Red Crescent Authority in Riyadh Region. AB - The Psychological Support Unit (PSU) performance in Saudi Red Crescent Authority (SRCA) showed that only a small number of case referred seeking psychological advice and management from PSU among all SRCA employees. However, research shows that between 28% and 52% of emergency medical services (EMS) providers usually seek psychological help in various EMS cultures, where 86% of them usually suffer from critical stress. Thus, we decided to design a quality improvement project that aims to improve the referral process by increasing cases referred to the PSU at SRCA in Riyadh Region by 75% in 2 months. A multidisciplinary team has been formed to analyse the problem using quality tools including, brainstorming, fishbone diagram and flow chart of the PSU processes. Several possible reasons have been identified, such as lack of awareness among the SRCA's employees about PSU and its services, and the concern about privacy and confidentiality during psychological consultations in the PSU, in addition to the long referring process to PSU. The team decided to test the following change ideas: increasing the awareness of employees about the PSU services, improving the privacy and confidentiality during the consultation using electronic channels, and finally re engineering the referral process to make it lean and remove all the unnecessary steps. Several improvement interventions have been tested sequentially in three consecutive Plan-Do-Study-Act cycles on a weekly basis. The project findings demonstrated that the first change idea was successful but not reaching the target while the second change had led to huge impact exceeding our target but with short effect. On the other hand, although the third change idea of re engineering the PSU referral process had led to negative result initially, over the following weeks of measurement the results turned to be positive and meeting our expectations. We concluded that re-engineering referral process is most effective improvement intervention among other change ideas in term of magnitude and sustainability of the effect on increasing the number of referral cases to the PSU. We recommend conducting further testing and measuring of these change ideas in other PSU across the SRCA to understand the diffident context in other regions of SRCA. PMID- 29450279 TI - Improving a process to obtain hepatitis B serology among patients treated with infliximab at a large urban children's hospital. AB - Background: Hepatitis B infection is a significant public health challenge despite improvements in vaccination efforts. Patients such as those on chronic immunosuppressive therapy for inflammatory bowel disease (IBD) or rheumatic disease may incur greater risk. The risk of reactivation of hepatitis B while on immunosuppressive therapy may have mortality rates up to 25%. These patients should be screened for acute or chronic infection and vaccinated if necessary. Our aim was to reliably complete hepatitis B screenings in patients receiving infliximab at Cincinnati Children's Hospital Medical Center (CCHMC). Methods: Eligible patients included all patients with gastroenterology (GI) IBD and rheumatology receiving infliximab between October 2015 and March 2016. Using quality improvement methodology and the 'plan-do-study-act' (PDSA) approach, interventions centred around education of clinical providers, previsit planning and the development of 'talking points' for patients. Results: An initial screen of the IBD population revealed that 48% of the IBD patient population had been screened for anti-HBs alone, but no patients from GI or rheumatology divisions had a complete set of hepatitis B serology prior to the intervention including anti-Hep B Core and Hep B Surface Antigen. Seven PDSA cycles were performed during the 32-week intervention period, resulting in an increase in patients screened from 0% to ~85%. By March 2016, a total of 251 patients (201 GI, 50 rheumatology) had up-to-date hepatitis B serology screening. Automated ordering of the hepatitis B serology and 'talking points' for the provider had the greatest impact on successful screening. Conclusions: We developed a method to obtain hepatitis B serology on at-risk patients on infliximab within two subspecialty divisions within a large children's hospital. Next steps will be to develop a process to reliably provide vaccines for patients who are seronegative, expand this process to all patients who are identified as immunocompromised within GI and rheumatology and then expand this process to other divisions at the CCHMC. PMID- 29450280 TI - Improving the patient booking service to reduce the number of missed appointments at East London NHS Foundation Trust Community Musculoskeletal Physiotherapy Service. AB - The East London National Health Service Foundation Trust (ELFT) Community Musculoskeletal (MSK) Physiotherapy Service had reported a high rate of non attendance at scheduled appointments. This was leading to delayed access to treatment for patients and a reduced capacity for service users, as well as a waste of clinical resources. The aim of this quality improvement project was therefore to reduce the percentage of missed appointments within this department. This study was undertaken by the ELFT community MSK service, with support from the ELFT Quality Improvement team. To begin with, patient complaints were explored; these indicated that the main reason for missing appointments was due to issues with the patient booking service. Baseline data were initially collected for both new referrals and follow-up patients. The proposed changes were then introduced, which included text message reminders, first via a manual platform and then via an automated system. Ongoing data were recorded to note the effectiveness of these changes. Following the intervention, non-attendance of newly referred patients reduced by 43.35% (23.76%-13.46%) after both cycles. Non attendance of follow-up patients reduced by 44.14% (23.74%-13.26%) after the second cycle alone. By listening to the opinions of service users, it was possible to improve the patient booking system and the flexibility of appointments. This resulted in a reduction in the percentage of appointments missed. These changes will continue to be monitored within this department to ensure sustainability but there is also now potential for similar interventions to be trialled in other health service departments. PMID- 29450281 TI - Improving communication between obstetric and neonatology teams for high-risk deliveries: a quality improvement project. AB - Summoning is a key component of communication between obstetrics and neonatal resuscitation team (NRT) in advance of deliveries. A paging system is a commonly used summoning tool. The timeliness and information contained in the page help NRT to optimally prepare for postdelivery infant care. Our aim was to increase the frequency that summoning pages contained gestational age and reason for NRT attendance to >90%. At baseline, 8% of pages contained gestational age and 33% of pages contained a reason for NRT attendance. Sequential Plan-Do-Study-Act cycles were used as our model for quality improvement. During the 8-month improvement period, the per cent of pages increased to 97% for gestational age and 97% for reason for NRT attendance. Measures of page timeliness, our balancing measure, did not change. Summoning communication between obstetric and NRT is crucial for optimal perinatal outcomes. The active involvement of all stakeholders throughout the project resulted in the development of a standardised paging tool and a more informative paging process, which is a key communication tool used in many centres. PMID- 29450282 TI - Implementation of a mock root cause analysis to provide simulated patient safety training. AB - Background: The proposed revision to the Accreditation Council for Graduate Medical Education (ACGME) Common Program Requirements includes participation in real or simulated patient safety activities, such as root cause analysis (RCA).1 Because exposure to RCA may occur with low frequency, a mock RCA was developed and piloted for feasibility with Hematology/Oncology fellows. Objective: To improve trainee knowledge of the goals and application of RCA in patient safety and quality improvement through a simulated experience. Methods: A mock RCA was implemented with Hematology/Oncology fellows over two subsequent years. In small groups, they reviewed a case involving an adverse event and identified sources of harm. Additional details, in the form of provider interviews, were available upon request. Trainees identified the root cause(s) and proposed measurable changes. Teams presented proposals to peers and a panel representing hospital leadership. Feedback was provided. Trainees completed evaluations and were surveyed regarding their perceptions. Results: Thirteen of 15 fellows completed the survey. Twelve of 13 (92%) fellows felt the mock RCA improved their comfort level for participation in a real RCA. Ten of 13 fellows (77%) reported increased awareness and likelihood of reporting near misses and/or adverse events following participation. More thorough patient care documentation following the session was reported by 8 of 13 (62%). Conclusion: A pilot trial of a mock RCA with Hematology/Oncology fellows had high trainee satisfaction. Post-session surveys and informal interviews suggest trainees have reduced anxiety when faced with participation in a real RCA and have more interest in the process after participation. PMID- 29450283 TI - Improving best possible medication history with vulnerable patients at an urban safety net academic hospital using pharmacy technicians. AB - Background: Best possible medication history (BPMH) enhances the care of safety net patients, especially those with limited English proficiency and limited health literacy who are most vulnerable to medication error during the hospital admission process. Our large urban academic safety net centre faced numerous barriers to achieve BPMH among hospitalised patients including communication barriers that increase the time and complexity of eliciting BPMH, frequent provider turnover at our training institution and lack of an electronic health record (EHR) medication reconciliation tool to facilitate BPMH collection and monitoring. Design: Leveraging opportunities afforded by the US federal incentive EHR programme, our multidisciplinary team designed an EHR-facilitated medication reconciliation programme by which pharmacy technicians engaged newly admitted patients and their caregivers at the bedside to develop and electronically document the BPMH. Strategy: Prior to this intervention, pharmacy technicians had no role in BPMH. Providers collected home medications documented on paper notes without a consistent methodology. With each plan-do-study-act (PDSA) cycle since the programme began, the goal was to increase the per cent of BPMH completed by a pharmacy technician. Individual PDSA cycles targeted either the pharmacy technicians by expanding their pool of eligible patients or provider engagement with the pharmacy technician workflow. Results: By optimising not only the health information technology platform but also the operational processes, the programme achieved a nearly 80% generation of BPMH completed by a highly trained pharmacy technician, surpassing its intended goal of 50% BPMH completion by a pharmacy technician on admission. Conclusion: An EHR-facilitated tool improved BPMH at an urban academic safety net hospital using pharmacy technicians. PMID- 29450284 TI - Reducing hospital admissions of healthy children with functional constipation: a quality initiative. AB - Functional constipation (FC) is a common medical problem in children, with minimal risk of long-term complications. We determined that a large number of children were being admitted to our children's hospital for FC in which there was no neurological or anatomical cause. Our hospital experienced a patient complication in which a patient died after inpatient treatment of FC. Subsequently, we developed a standardised approach to determine when paediatric patients needed hospitalisation for FC, as well as to develop a regimented outpatient therapeutic approach for such children to prevent hospitalisation. Our quality improvement initiative resulted in a large decrease in the number of children with FC admitted into the hospital as well as a decrease in the number of children needing faecal disimpaction in the operating room. Our quality improvement process can be used to decrease hospitalisations, decrease healthcare costs and improve patient care for paediatric FC. PMID- 29450285 TI - Reducing medical-surgical inpatient falls and injuries with videos, icons and alarms. AB - Background: Inpatient falls and subsequent injuries are among the most common hospital-acquired conditions with few effective prevention methods. Objective: To evaluate the effectiveness of patient education videos and fall prevention visual signalling icons when added to bed exit alarms in improving acutely hospitalised medical-surgical inpatient fall and injury rates. Design: Performance improvement study with historic control. Setting: Four medical-surgical units in one US public acute care hospital. Study participants: Adult medical-surgical inpatients units. Interventions: A 4 min video was shown to patients by trained volunteers. Icons of individual patient risk factors and interventions were placed at patients' bedsides. Beds with integrated three-mode sensitivity exit alarms were activated for confused patients at risk of falling. Main outcome measures: The main outcome measure is the incident rate per 1000 patient days (PDs) for patient falls, falls with any injury and falls with serious injury. The incident rate ratio (IRR) for each measure compared January 2009-September 2010 (baseline) with the follow-up period of January 2015-December 2015 (intervention). Results: Falls decreased 20% from 4.78 to 3.80 per 1000 PDs (IRR 0.80, 95% CI 0.66 to 0.96); falls with any injury decreased 40% from 1.01 to 0.61 per 1000 PDs (IRR 0.60, 95% CI 0.38 to 0.94); and falls with serious injury 85% from 0.159 to 0.023 per 1000 PDs (IRR 0.15, 95% CI 0.01 to 0.85). Icons were not fully implemented. Conclusion: The first known significant reduction of falls, falls with injury and falls with serious injury among medical-surgical inpatients was achieved. Patient education and continued use of bed exit alarms were associated with large decreases in injury. Icons require further testing. Multicentre randomised controlled trials are needed to confirm the effectiveness of icons and video interventions and exit alarms. PMID- 29450286 TI - From research to practice: results of 7300 mortality retrospective case record reviews in four acute hospitals in the North-East of England. AB - Introduction: Monitoring hospital mortality using retrospective case record review (RCRR) is being adopted throughout the National Health Service (NHS) in England with publication of estimates of avoidable mortality beginning in 2017. We describe our experience of reviewing the care records of inpatients who died following admission to hospital in four acute hospital NHS Foundation Trusts in the North-East of England. Methods: RCRR of 7370 patients who died between January 2012 and December 2015. Cases were reviewed by consultant reviewers with support from other disciplines and graded in terms of quality of care and preventability of deaths. Results were compared with the estimates published in the Preventable Incidents, Survival and Mortality (PRISM) studies, which established the original method. Results: 34 patients (0.5%, 95% CI 0.3% to 0.6%) were judged to have a greater than 50% probability of death being preventable. 1680 patients (22.3%, 95% CI 22.4% to 23.3%) were judged to have room for improvement in clinical, organisational (or both) aspects of care or less than satisfactory care. Conclusions: Reviews using clinicians within trusts produce lower estimates of preventable deaths than published results using external clinicians. More research is needed to understand the reasons for this, but as the requirement for NHS Trusts to publish estimates of preventable mortality is based on reviews by consultants working for those trusts, lower estimates of preventable mortality can be expected. Room for improvement in the quality of care is more common than preventability of death and so mortality reviews contribute to improvement activity although the outcome of care cannot be changed. RCRR conducted internally is a feasible mechanism for delivering quantitative analysis and in the future can provide qualitative insights relating to inhospital deaths. PMID- 29450287 TI - Reducing radiation hazard opportunities in neonatal unit: quality improvement in radiation safety practices. AB - Aim: Guided by the ALARA - "As Low As Reasonably Achievable" principle in radiation safety, a quality improvement project to optimise the bedside diagnostic imaging process to the best standards of care was conducted over a six month period. The goal was too reduce the radiation hazard opportunities in the neonatal intensive care unit by at least 75% from the existing level at Q2/2015, within 6 months. Methods: The existing bedside imaging process was critically analysed and the following quality improvement initiatives were implemented namely, mandatory lead protective gear to healthcare staff, gonadal shield for neonates, guidelines for optimal collimation of X-ray beam and optimal positioning of neonates. Radiation dosimetry results, regular staff awareness sessions and strong collaboration between neonatologists, radiologists, radiographers and neonatal nurses helped to ensure compliance to the revised imaging process. Radiation hazard opportunities were measured by analysing all radiographs done during the period under baby exposure and healthcare staff exposure categories. Summary of results: Radiation hazard opportunities were reduced by 100% to healthcare staff and 75% to neonates, and the overall reduction was 83%. The rate of discordance between radiograph request forms and images taken was measured as a surrogate marker for compliance to the project initiatives and it declined by 77%. Mandatory orientation of staff to the revised policy on the standardised diagnostic imaging process, regular radiation awareness talks and staff feedback sessions are among several measures taken to sustain the project. PMID- 29450288 TI - Improving care collaboration for NICU patients to decrease length of stay and readmission rate. AB - Background: Medically complex patients in neonatal intensive care units (NICUs) typically require long hospitalisations and care from multiple subspecialists. Scheduled multidisciplinary discussions could improve collaboration and continuity of care and thereby improve patient outcomes. The specific aims of the project were to decrease the average length of hospitalisation by at least 1 day and improve parent satisfaction ratings on a standard questionnaire by the end of our project's first year, and to maintain a stable (or decreased) cause-related (30-day) readmission rate. Methods: We designed a quality improvement project to enhance collaboration and continuity of care for medically complex infants cared for in the NICU of Brenner Children's Hospital. Weekly multidisciplinary team meetings were held to discuss the long-term plan for patients who met specific criteria. Attendees included attending neonatologists, paediatric surgeons, a physical therapist, an occupational therapist, a speech therapist, a social worker, a nurse coordinator for palliative care, a family support coordinator, the NICU Nurse Manager, a hospital chaplain, mid-level providers, bedside nurses, a nurse quality improvement leader and the leaders and database manager for the quality improvement project. When needed for specific patients, a bioethicist was included. Results: One year after implementing the project, the average duration of hospitalisation had decreased by 6.5 days. Cause-related readmission rates decreased from 3.33% to 0.95%. Parent satisfaction scores did not change significantly. Conclusions: Weekly multidisciplinary meetings to coordinate and provide continuity of care for medically complex neonates in our NICU was associated with improved patient outcomes. PMID- 29450289 TI - Improving combined contraceptive pill/oral contraceptives prescribing in general practice. AB - Introduction: Eighty per cent of contraceptive care occurs in the general practice setting. UK Medical Eligibility Criteria provides clear guidelines for the safe provision of appropriate contraception. The Faculty of Sexual and Reproductive Health and the National Institute for Health and Care Excellence offer further recommendations for initiation and continuation of the combined contraceptive pill/oral contraceptives. Method and analysis: Using the Egton Medical Information Systems database of an inner city, average size general practice we performed a retrospective analysis of combined contraceptive pill/oral contraceptives consultations to identify areas of substandard prescribing. Through three subsequent improvement cycles we demonstrated that the safety of combined contraceptive pill/oral contraceptives prescribing could be enhanced by consistent application of UK Medical Eligibility Criteria. By encouraging general practitioners to promote safe sex and use local long-acting reversible contraception options we were able to enhance the quality of consultations as dictated by national guidelines. Regular education and use of an amended EMIS template (to include UK Medical Eligibility Criteria) enabled us to improve both the safety and quality of community-combined contraceptive pill/oral contraceptives prescribing in a sustainable fashion. PMID- 29450290 TI - Improving the rates of electronic results acknowledgement at a tertiary eye care centre. AB - Background: Hundreds of thousands of tests are performed annually in hospitals worldwide. Safety Issues arise when abnormal results are not recognized promptly resulting in delayed treatment and increased morbidity and mortality. As a result Singapore's largest healthcare group, Singhealth introduced an electronic result acknowledgement system. This system was adopted by the Singapore National Eye Centre (SNEC) in February 2016. Baseline measurements show that weekly numbers of unacknowledged results ranged from 193 to 617. The current standards of electronic results acknowledgement posts a significant patient safety hazard. Methods: Root cause analysis was performed to identify contributory factors. Pareto principle was then used by the authors to identify the main contributory factors. We employed the rapid cycle improvement Plan-do-study-act (PDSA) strategy to test and evaluate implemented changes. Changes are implemented for 2 weeks and data collected prospectively. The data is analyzed the week after and the following PDSA actions are decided and instituted the following week. 3 PDSA cycles were undertaken in total. Results: The first PDSA cycle focused on raising awareness of the problem at hand, the number of unacknowledged results drastically decreased during the 1stweek of implementation of our PDSA from 617 to 254. The second PDSA cycle targeted the lack of knowledge of doctors involved in the electronic result acknowledgement process. There was a trend downwards near the end of the cycle which continued through the week after. The third PDSA cycle targeted individual doctors and provided individual remedial training. Second line doctors were also equipped to better handle abnormal results. There was significant improvement with the number of unacknowledged abnormal results dropping to <5 a week. Conclusions: Multiple factors were identified to contribute to the low compliance to electronic acknowledgement of results. The role doctors play in the issue at hand was paramount and required careful handling in a professional manner with multiple reminders and emphasis on the importance of acknowledging and acting on the results.A significant improvement in the rates of acknowledgement of abnormal results was demonstrated with clear benefits to patient safety. Interventions can be replicated when implementing similar systems to other areas of healthcare. PMID- 29450291 TI - The game of telephone: a sustained, low-cost, quality improvement initiative to enhance communication between patients and their resident physician. AB - This multidisciplinary quality improvement project was designed to enhance telephone communication between patients and their resident physician while concomitantly creating a standardised telephone communication protocol for resident internal medicine continuity clinics. The plan, do, study, act (PDSA) quality improvement framework model was applied for four distinct cycles. Baseline data were collected regarding open telephone encounters. The initial intervention entailed targeted communication to specific individual residents with open telephone encounters more than one SD above the average. The next cycle involved developing a novel communication process map that was distributed to faculty preceptors and clinic anchor nurses. The faculty preceptors then disseminated the new policies and communication algorithm to resident physicians. Finally, new resident and anchor nurses were educated about the standardised processes through scheduled orientation activities. After 19 months of implementation of this project with four PDSA cycles, resident open telephone encounters decreased by 40.7%. Resident telephone communication in continuity clinics can be improved through targeted individualised communication, implementation of a standardised telephone communication protocol, dissemination of communication algorithms to clinic faculty, residents and nurses and ongoing education to all parties through orientation activities to instil a self sustaining culture change. PMID- 29450292 TI - Using 'Active Signposting' to streamline general practitioner workload in two London-based practices. AB - General practice is at the forefront of the National Health Service, but is currently being overwhelmed by ever-increasing patient demand and financial constraints. Telephone consultations (TCs) have been used as a method to ease pressure on general practice. Many of these consultations are booked with general practioners (GPs), despite occasions when the patient could have either been signposted to self-help or offered an alternative service. This quality improvement project (QIP) aimed to evaluate the nature of TCs undertaken by GPs at our two practices; and whether the patients' needs could have adequately been met without the involvement of a GP. Consultations where this was the case were deemed 'possibly avoidable', and those where involvement with a GP was the best option have been termed 'essential'. A retrospective analysis was undertaken to establish a baseline figure for the proportion of possibly avoidable TCs in two practices. A new intervention was then introduced, with reception staff following a set of protocols when booking in patients. Patients who did not require a GP to deal with their query were actively signposted by reception staff to other allied healthcare professionals, non-medical staff or an alternative service at the time of booking their appointment. Two practices were involved in the study. After 2 Plan, Do, Study, Act (PDSA) cycles, the proportion of essential consultations taking place at both practices increased from 28.6% and 27.3% at baseline, to 82.6% and 71.4%, respectively. A lower number of possibly avoidable TCs equates to more time for essential TCs and greater value for money for the practice. Patient access to care is also improved, with patients directed to alternative and often quicker services which still meet their needs adequately. With the current system of primary care unable to cope with the demands it faces, interventions such as active signposting provide value for both GP practices and patients alike. PMID- 29450293 TI - Right service, right place: optimising utilisation of a community nursing service to reduce planned re-presentations to the emergency department. AB - Background: Congruent with international rising emergency department (ED) demand, a focus on strategies and services to reduce burden on EDs and improve patient outcomes is necessary. Planned re-presentations of non-urgent patients at a regional Australian hospital exceeded 1200 visits during the 2013-2014 financial year. Planned re-presentations perpetuate demand and signify a lack of alternative services for non-urgent patients. The Community Nursing Enhanced Connections Service (CoNECS) collaboratively evolved between acute care and community services in 2014 to reduce planned ED re-presentations. Objective: This study aimed to investigate the evolution and impact of a community nursing service to reduce planned re-presentations to a regional Australian ED and identify enablers and barriers to interventionist effectiveness. Methods: A mixed methods approach evaluated the impact of CoNECS. Data from hospital databases including measured numbers of planned ED re-presentations by month, time of day, age, gender and reason were used to calculate referral rates to CoNECS. These results informed two semistructured focus groups with ED and community nurses. The researchers used a theoretical lens, 'diffusion of innovation', to understand how this service could inform future interventions. Results: Analyses showed that annual ED planned re-presentations decreased by 43% (527 presentations) after implementation. Three themes emerged from the focus groups. These were right service at the right time, nursing uncertainty and system disconnect and medical disengagement. Conclusions: CoNECS reduced overall ED planned re-presentations and was sustained longer than many complex service-level interventions. Factors supporting the service were endorsement from senior administration and strong leadership to drive responsive quality improvement strategies. This study identified a promising alternative service outside the ED, highlighting possibilities for other hospital emergency services aiming to reduce planned re presentations. PMID- 29450294 TI - Improvement in patient and physician notification of cardiac rhythm device report transmissions. AB - Background Cardiac rhythm devices (CRD) require complex management to identify potential device or patient issues. While easy to obtain, report processing is complex and time consuming. In our population, a majority of reports were performed outside of institutional protocols and no method for electrophysiology (EP) notification for unscheduled reports existed. These process breakdowns led to potential issues with safety and associated loss of work efficiency. Objective Our aim was to decrease the percentage of reports without EP notification from 30% to 10% over a 9-month time period. Methods We created a detailed process map of in-office and home device reporting. Failure mode and effects analysis (FMEA)/Pareto charts were used to determine the mechanistic underpinnings of notification failures and identify areas for process improvement. Multiple interventions were implemented using the Plan-Do-Study-Act (PDSA) technique. Process run charts and control charts were used to evaluate ongoing changes. Results Our FMEA identified failures related to (1) lack of physician understanding of the device reporting system, (2) lack of an easy to use method of EP notification and (3) lack of patient understanding of report notification. Pareto charts identified the most frequent failures to be associated with specific cardiology subspecialties as well as reports sent from home. We performed multiple interventions including(1) creation of an easy to use method of EP notification used by patients and medical staff, (2) physician education and (3) patient education. Compared with baseline reporting, there was a decrease from 30% to <10% of device reports obtained without EP notification. This process improvement additionally resulted in a 34% reduction in time required for device processing. Conclusions Development of a unified EP reporting system and quality improvement methodology resulted in improved CRD report notification and improved efficiency for staff. These process changes resulted in improvement across differing cardiac subspecialty providers and patients. PMID- 29450295 TI - Reducing patient mortality, length of stay and readmissions through machine learning-based sepsis prediction in the emergency department, intensive care unit and hospital floor units. AB - Introduction: Sepsis management is a challenge for hospitals nationwide, as severe sepsis carries high mortality rates and costs the US healthcare system billions of dollars each year. It has been shown that early intervention for patients with severe sepsis and septic shock is associated with higher rates of survival. The Cape Regional Medical Center (CRMC) aimed to improve sepsis-related patient outcomes through a revised sepsis management approach. Methods: In collaboration with Dascena, CRMC formed a quality improvement team to implement a machine learning-based sepsis prediction algorithm to identify patients with sepsis earlier. Previously, CRMC assessed all patients for sepsis using twice daily systemic inflammatory response syndrome screenings, but desired improvements. The quality improvement team worked to implement a machine learning based algorithm, collect and incorporate feedback, and tailor the system to current hospital workflow. Results: Relative to the pre-implementation period, the post-implementation period sepsis-related in-hospital mortality rate decreased by 60.24%, sepsis-related hospital length of stay decreased by 9.55% and sepsis-related 30-day readmission rate decreased by 50.14%. Conclusion: The machine learning-based sepsis prediction algorithm improved patient outcomes at CRMC. PMID- 29450296 TI - Reducing bed occupancy and length of stay on a functional older adults' psychiatric ward. AB - A quality improvement project was initiated on Ivory ward, a functional older adult psychiatric inpatient ward at Newham Centre for Mental Health, part of the East London NHS Foundation Trust. The project was started by staff on the ward after it had come to their attention that their ward had the highest bed occupancy and length of stay across similar wards in the trust. The mean bed occupancy in the 9 months before the project started was 87.7%. The mean length of stay on the ward in the 9 months before the project started was 70 days. The team used the model for improvement, which is the trust's methodology of choice for quality improvement projects, to reduce bed occupancy and length of stay. The focus was on running small-scale tests of change to see whether these could lead to improvement. These change ideas were refined, scaled up or discontinued as appropriate to help achieve the aim. The project's aim was to promote quality of care by reducing patient length of stay on Ivory ward to 45 days and bed occupancy to <=70% or by 1 January 2016. The project team managed to reduce bed occupancy to 58% and length of stay to an average of 35 days. PMID- 29450297 TI - Improving venous thromboembolism risk assessment rates in a tertiary urology department. AB - Venous thromboembolism (VTE) is a significant cause of mortality and morbidity among hospitalised patients. A VTE risk assessment reduces this through facilitating correct prophylaxis. Since 2010, the Commissioning for Quality and Innovation payments framework dictates that >95% adult inpatients must have a VTE risk assessment within 24 hours of admission. This target is not currently being met by the urology department at Guy's and St. Thomas' Trust (GSTT). Following analysis, a quality improvement project aimed to increase VTE risk assessment rates for patients admitted under urology at GSTT. Two series of interventions were introduced following the Plan, Do, Study, Act structure aimed at urology theatres and wards, respectively. These boosted awareness of the VTE risk assessment and streamlined it into routine surgical workload. Despite not reaching the 95% target, the project increased rates among patients admitted directly to surgical units by 5%-8%. It highlighted the difficulties in driving a change in established routine and demonstrated a need for firmer interventions with effective communication. PMID- 29450298 TI - Improving transitions of care: a resident-driven approach to address delays in patient care during the direct admission process. AB - Background: The direct admission process is a complex system that can be aggravated by inherent gaps in communication leading to inefficient continuity of care and patient safety issues. Bypassing the emergency room, triage is often associated with long periods of unmonitored observation and significant delays in patient assessment. We identified significant communication gaps, delays in placement of admission orders and patient assessment during the direct admission process at our institution. To address this issue, we created and implemented a standardised direct admission flow diagram that consists of a step-by- step direct admission process, which includes a communication device and a triage power plan in the Electronic Medical Record. Methods: We used the Plan-Do-Study Act (PDSA) model for Quality improvement to address communication gaps in the direct admission process Baseline measurement confirmed two critical gaps in communication: 1) communication to the Medical Admitting Resident (MAR), the central source of communication of all medicine admissions, and 2) delays in placement of orders and assessment of the patient. Results: Two months after implementation of a standardised process that addressed the two major gaps in communication, we found that communication to the MAR increased from 16% (7/42) to 100% (15/15). Additionally, the average time for order placement and assessment of patient decreased from 153 minutes to 53 minutes (n=15). Conclusion: In order to improve the safety of direct admissions, the entire process must be carefully analysed and potential delays in patient assessment should be minimised. A standardised flow diagram that identified and targeted specific communication gaps can minimise delays in patient care. PMID- 29450299 TI - Reducing hypothermia in newborns admitted to a neonatal care unit in a large academic hospital in New Delhi, India. AB - Neonatal hypothermia is a common and dangerous condition around the world. 70% of neonates born in Kalawati Saran Children's Hospital in New Delhi, India, and subsequently admitted to the neonatal intensive care unit (NICU) had a temperature below 36.5 degrees C on admission. In July 2016, we formed a team of staff from the labour room, NICU and auxiliary staff to reduce hypothermia in babies transported to our NICU using quality improvement methods. We identified problems related to staff awareness of hypothermia and its dangers, environmental factors and supply issues in the labour room, and challenges with rapidly and safely transferring sick newborns to the NICU. We used the Plan-Do-Study-Act cycles to test and adapt solutions to these problems. Because infection is a common complication of hypothermia, we also instituted a training programme to improve handwashing skills among parents and health workers. Within 9 months of starting our quality improvement project, the proportion of neonates who were normothermic on admission increased from 27% to 75%, the number of cases of late onset neonatal sepsis decreased from 15.2 to 5 cases/1000 patient days, and all cause mortality fell from 4.2 to 2.6 neonatal deaths per week. Multiple factors can lead to neonatal hypothermia, and the most important factors will differ from facility to facility. Quality improvement methods provide health workers with the skills to identify the key factors contributing to hypothermia in their facility and to develop strategies to address them. Addressing processes of care can lead to improved thermal care and save lives. PMID- 29450300 TI - Optimisation of intravenous fluid prescribing: framework for changing practice through education and audits. AB - Introduction: Intravenous fluids are one of the most commonly prescribed drugs in the hospital setting and yet the practice continues to fall short of National Institute for Health and Care Excellence (NICE) guidelines, with significant gaps in staff knowledge exposing patients to heightened morbidity and mortality. Aim: Following the 2013 publishing of updated NICE guidelines on intravenous fluid prescribing, an intravenous fluid team was formed within the Royal Liverpool University Hospital (RLUH). Their role has been (and continues to be) to overhaul the culture of suboptimal intravenous fluid prescribing within the hospital and, ultimately, to improve patient outcomes. A framework to engender this change has been developed and is offered as an example to other Trusts within which improvement of guideline-compliant intravenous fluid prescribing remains stagnant. Method: There have been three principal stages of the project to this point which are best demonstrated in a chronological manner. The period of 2010 2014 allowed for assessment of the issue of intravenous fluid prescribing and analysis of its causes through serial audits and a staff-wide survey. From 2015, there has been implementation of several measures (educative, managerial, administrative and technological) within the hospital to foster reproducible and positive change with regards to intravenous fluid prescribing. Finally, between 2016 and 2017, three cycles of a rolling audit based on NICE guidelines have been completed to allow measurement of improvement in intravenous fluid prescribing practice. Conclusion: Results have demonstrated a significant improvement in the appropriateness of the intravenous maintenance and replacement fluids prescribed in the hospital since the March 2016 audit. Moreover, a 29-fold increase has been observed in the use of 4% dextrose/0.18% sodium chloride as maintenance fluid (gold standard as per NICE guidelines) since the staff-wide survey of 2015. Despite progress however, adherence to NICE guidelines remains below the recommended 100% and therefore further work remains to be done. PMID- 29450301 TI - Preventing cerebral palsy in preterm labour: a multiorganisational quality improvement approach to the adoption and spread of magnesium sulphate for neuroprotection. AB - Magnesium sulphate has been demonstrated to be an effective neuroprotectant for babies delivered prematurely (under 37 weeks' gestational age). Antenatal administration reduces infant mortality and cerebral palsy (CP); however, uptake in the UK has been significantly lower than other countries. A quality improvement (QI) project (PReventing Cerebral palsy in Pre Term labour (PReCePT)) was carried out in the West of England, UK, to raise awareness of evidence and to improve the uptake of magnesium sulphate as neuroprotectant in preterm deliveries. Five National Health Service (NHS) Trusts and the West of England Academic Health Science Network participated in the QI project. The project was underpinned by a multifaceted QI approach that included: patient and clinical coproduction of resources; recruitment of clinical champions to support the local microsystems and create a stimulating/supporting environment for change; Plan, Do, Study, Act cycles; training for over 600 NHS staff and awareness raising and strategic influencing of key leaders. A baseline audit and regular measurement of the number of eligible women receiving magnesium sulphate was undertaken at each hospital site, and the overall programme was evaluated using data from an international benchmarking organisation for neonatal care outcomes-the Vermont Oxford Network. During the project 664 staff received magnesium sulphate training. The use of magnesium sulphate increased across the West of England from an average baseline of 21% over the 2 years preceding the project to 88% by the conclusion of the project. The project was also able to influence the development of a national data collection process for benchmarking the use of magnesium sulphate for neuroprotection in preterm deliveries in the U.K. PReCePT appears to have had a favourable effect on the uptake of magnesium sulphate across the West of England. The project has also provided learning about how to stimulate adoption and spread of evidence using a QI approach across a network. PMID- 29450302 TI - How Kabarole Hospital in western Uganda saved mothers' lives through team-based problem-solving. PMID- 29450303 TI - Monitoring long-term oral corticosteroids. AB - Corticosteroids are synthetic analogues of human hormones normally produced by the adrenal cortex. They have both glucocorticoid and mineralocorticoid properties. The glucocortoid components are anti-inflammatory, immunosuppressive, anti-proliferative and vasoconstrictive. They influence the metabolism of carbohydrate and protein, in addition to playing a key role in the body's stress response. Mineralocorticoid's main significance is in the balance of salt and water concentrations. Due to the combination of these effects, corticosteroids can cause many adverse effects. Oral corticosteroids are absorbed systemically and are therefore more likely to cause adverse effects than topical or inhaled corticosteroids. Furthermore, it is assumed that greater duration of treatment will lead to a greater number of adverse effects, and therefore the most at risk group are those taking high dose, long-term oral corticosteroids (LTOC). High dose is defined as a prescription of >5 mg oral prednisolone and long term as duration of treatment >1 month (based on National Institute for Health and Care Excellence guidance for patient's 'at risk' of systemic side effects). Parameters to be monitored in primary care include weight, blood pressure, triglycerides, glucose and urea and electrolytes. From clinical experience within the general practice setting, the authors propose that these patients do not receive adequate baseline monitoring before starting corticosteroids nor are these markers monitored consistently thereafter. This project intended to evidence this claim, evaluate the adverse effect profile and improve monitoring in this patient group. The initial audit of 22 patients, within a single general practice, detected at least one documented adverse effect in 64% of patients, while 41% reported more than one adverse effect. 45% had recorded weight gain, 18% had recorded osteoporosis, 18% had at least one recorded cataract, 14% had recorded Hypertension, 14% had recorded diabetes mellitus, 9% had recorded dyspepsia and 5% had a recorded psychiatric complaint. All of these recorded conditions were either directly attributed to steroid medication or occurred since LTOC were prescribed. The aim of this project was to increase the percentage of patients on LTOC with complete baseline monitoring to 100%. 'Baseline monitoring' was defined as a measurement taken within the previous 5 years. Although somewhat arbitrary, 5 years was felt to be the maximum timeframe in which monitoring would still be relevant for comparison following introduction of LTOC. Quality improvement methodology was used throughout this project with multiple PDSA (Plan, Study, Do and Act) cycles. Through this, a monitoring system and protocol for patients taking LTOC was developed. As a result of this project, five adverse effects were detected in five different patients. These included two cases of secondary hypertension, one case of diabetes mellitus, one cataract and one case of adrenal insufficiency. 12 out of 20 patients achieved complete baseline monitoring. While this study did not fully achieve its aim, the aim was deliberately ambitious. As not all patients in this study attended for monitoring, a figure of 100% was impossible to achieve. The remaining 'incompletely monitored patients' had some but not all parameters measured. The creation of a staff protocol and increased clinical experience will ensure that complete monitoring takes place in the future. In conclusion, this project has shown that adverse effects from LTOC are prevalent in a single general practice population. It is also shown that monitoring for LTOC adverse effects is inadequate but can be improved relatively easily as skills and competencies from other medication monitoring systems already exist within healthcare settings and are immediately transferable. PMID- 29450304 TI - Use of audit, feedback and education increased guideline implementation in a multidisciplinary stroke unit. AB - Background: The audit-feedback cycle is a behaviour change intervention used to reduce evidence-practice gaps. In this study, repeat audits, feedback, education and training were used to change practice and increase compliance with Australian guideline recommendations for stroke rehabilitation. Objective: To increase the proportion of patients with stroke receiving best practice screening, assessment and treatment. Methods: A before-and-after study design was used. Data were collected from medical records (n=15 files per audit). Four audits were conducted between 2009 and 2013. Consecutive files of patients with stroke admitted to the stroke unit were selected and audited retrospectively. Staff behaviour change interventions included four cycles of audit feedback, and education to assist staff with change. The primary outcome measure was the proportion of eligible patients receiving best practice against target behaviours, based on audit data. Results: Between the first and fourth audit (2009 and 2013), 20 of the 27 areas targeted (74%) met or exceeded the minimum target of 10% change. Practice areas that showed the most change included sensation screening (+75%) and rehabilitation (+100%); neglect screening (+92%) and assessment (100%). Some target behaviours showed a drop in compliance such as anxiety and depression screening (-27%) or little or no overall improvement such as patient education about stroke (6% change). Conclusions: Audit feedback and education increased the proportion of inpatients with stroke receiving best practice rehabilitation in some, but not all practice areas. An ongoing process of quality improvement is needed to help sustain these improvements. PMID- 29450305 TI - The grimace scale reliably assesses chronic pain in a rodent model of trigeminal neuropathic pain. AB - The limited success in translating basic science findings into effective pain management therapies reflects, in part, the difficulty in reliably assessing pain in experimental animals. This shortcoming is particularly acute in the field of chronic, ongoing pain. Quantitative analysis of facial expressions-the grimace score-was introduced as a promising tool, however, it is thought to reliably assess only pain of short or medium duration (minutes to hours). Here, we test the hypothesis that grimace scores are a reliable metric of ongoing neuropathic pain, by testing the prediction that chronic constriction injury of the infraorbital nerve (CCI-ION) will evoke significant increases in grimace scale scores. Mice and rats were subjected to CCI-ION, and tested for changes in mechanical hypersensitivity and in grimace scores, 10 or more days after surgery. Both rats and mice with CCIION had significantly higher grimace scores, and significantly lower thresholds for withdrawal from mechanical stimuli applied to the face, compared to sham-operated animals. Fentanyl reversed the changes in rat grimace scale scores, suggesting that these scores reflect pain perception. These findings validate the grimace scale as a reliable and sensitive metric for the assessment of ongoing pain in a rodent model of chronic, trigeminal neuropathic pain.

AB - Angle-closure glaucoma includes a number of entities with closed angle, elevated intraocular pressure, in association with optic nerve damage and visual field defects as common markers. These entities are characterized by irido-trabecular apposition, irido-trabecular synechiae or both. The angle configuration must be systematically checked at least one time in patients presenting with raised intraocular pressure or glaucoma. Gonioscopy represented for a long time the gold standard for clinically assessing anterior chamber angle structures and their configuration. However, the interpretation of gonio-scopic findings is subjective and only semiquantitative. With the development of new imaging techniques of the anterior segment, new analysis methods have also emerged. Ultrabiomicroscopy was the first method of analyzing the anterior segment and is still the only imaging technique for all anterior segment structures (especially the ciliary body). Another method is optical coherence tomography, a non-contact technique by which angle configuration can be assessed in a more rapid and less invasive manner. Recently developed Pentacam technology could represent in the near future a more quantitative, rapid and non-invasive screening tool which could allow early detection of angle closure glaucoma and narrow angle configurations by measuring a set of anterior chamber parameters. List of abbreviations: ACG -angle closure glaucoma, ASOCT-anterior segment optical coherence tomography UMB- ultrasound biomicroscopy (ultrabiomicroscopy), PAS-posterior angle synechiae ACD-anterior chamber depth, ACV-anterior chamber volume, PLI-periphery laser iridotomy. PMID- 29450310 TI - The influence of optical aberrations in refractive surgery. AB - Optical aberrations lead to defects in image-forming, the image obtained being imperfect and thereby decreasing the quality of vision. When an optic system is not perfect, as happens with the eye, the rays of light that pass through the system produce optical aberrations. The purpose of this review is to describe optical aberrations and their impact on vision and how refractive surgery outcomes are influenced by them. The main optical aberrations of the eye are as follows: spherical aberration, chromatic aberration, oblique astigmatism and high order aberrations. When the patient undergoes various types of surgeries (cataract surgery, corneal refractive surgery) the properties of the eye change and the eye doctor must take into account the correction of optical aberrations to improve vision quality. Abbreviations: LASIK (laser in situ keratomileusis), PRK (photorefractive keratectomy), UDVA (uncorrected distance visual acuity), SA (spherical aberrations), HOA (higher-order aberrations), RMS (root mean square). PMID- 29450311 TI - National centers of excellence in glaucoma. AB - Glaucoma refers to a group of related eye disorders that have in common an optic neuropathy associated with visual function loss. It is the second leading cause of blindness in developed countries and Romania and the first cause of irreversible blindness worldwide. In Europe, 2% of the population over 40 and 7% of the population over 80 have glaucoma. In Romania, there are no official statistics concerning glaucoma disease, but it was estimated that over 160000 Romanians suffer from this disease and only 50% of them are undergoing treatment. The silent evolution of the disease, the deficient sanitary education, the lack of well structured national programs for screening and follow-up and the lack of adherence to treatment and check-ups, are the causes of late diagnosis and irreversible visual function loss. The article emphasizes the need for national centers specialized in managing patients with glaucoma, from prevention, screening, early diagnosis to treatment and monitoring. PMID- 29450312 TI - Retrocorneal membranes after penetrating keratoplasty. AB - Purpose. To present a rare complication after penetrating keratoplasty. Methods. The review presents the main types of retrocorneal membranes. The incidence, pathophysiology, diagnosis and treatment are shown for all of them. Conclusions. The evaluation and management of a membrane behind the posterior surface of the cornea is a special challenge for ophthalmologists. The clearer understanding of the pathogenesis of the different types of retrocorneal membranes may allow a more specific and efficient treatment. PMID- 29450314 TI - Intraoperative and postoperative complications in trabeculectomy, Clinical study. AB - Glaucoma represents a progresive multifactorial optic neuropathy characterised by retinal ganglion cell loss and atrophy of the optic nerve its main cause being high intraocular pressure. [1,2] Trabeculectomy is the most used surgical method when it comes to the majority of the ophthalmologists which is why knowing and managing the intraoperative and postoperative complications well is very important. [3] Objective/aim.The study aims to establish the success rate and to evaluate the intraoperative and postoperative complications in a group of 75 patients with glaucoma 1 year after surgery. Methods. A retrospective study was made on a group of 75 adult patients with different types of glaucoma which were refractory to medical treatment, for whom the treatment option was the trabeculectomy surgical intervention . Results and discussions. The success rate measured 1 year after the surgery was of 89%.The most complications were found in patients with open angle glaucoma, neovascular glaucoma and glaucoma secondary to vitreo-retinal surgery. Trabeculectomy is a surgical procedure associated with numerous complications, so much so that the follow-up and the management of the aforementioned complications are sometimes more laborious than the surgery itself. PMID- 29450313 TI - Anti-vascular endothelial growth factor indications in ocular disease. AB - The purpose of this systemic review was to investigate the indications of anti vascular endothelial growth factor (anti-VEGF) in the treatment of ocular diseases. For this, a comprehensive literature research was performed exploring the current use of anti-VEGF in a variety of retinal or anterior segment diseases and highlighting the visual outcome for these patients. The anti-VEGF therapy is now commonly used for a wide range of pathologies like age-related macular degeneration, retinal vein occlusion or diabetic retinopathy. Pathological processes such as abnormal neovascularization, ocular angiogenesis and macular edema which can greatly reduce visual acuity are now targeted by anti-VEGF treatment, having a major impact on vision. PMID- 29450315 TI - Partial results after treatment of diabetic macular edema with Bevacizumab. AB - Purpose: To present the morphological and functional results after treating diabetic macular edema with Bevacizumab. Patient and method: It is a prospective trial which includes 15 patients with diabetic macular edema (proved by OCT and fluorescein angiography examination). The inclusion criteria are: central retinal thickness over 250 um, visual acuity of the studied eye between 0.1 and 0.5, absence of a previous treatment. We excluded patients with macular edema caused by other ethiology or with any other macular disease. Every patient was treated with 3 intravitreal injections with Bevacizumab at every 6 weeks; we analyzed the results after 4 months. Results: The mean visual acuity improved from 0.33 +/- 0.06 at baseline to 0.49 +/- 0.13 at 4 months (or from 31+/-3.9 ETDRS letters to 39+/-5.67 letters). The central retinal thickness decreased from 457 +/- 174 um to 338 +/- 139 um. There was also an improvement of retinal sensibility on the microperimetry map. Conclusions: The treatment of diabetic macular edema produced an increase of visual acuity and a decrease of macular thickness after the first 3 injections with Avastin, but it is necessary to monitor the patients to detect the rebound of the edema and to initiate retreatment. PMID- 29450316 TI - Corneal hysteresis and primary open angle glaucoma. AB - Objects: To investigate the variability of the corneal hysteresis in primary open angle glaucoma(POAG) patients. Material and Methods: Out of 123 eyes, 99 carried out the inclusion criteria and were investigated further using Goldman Aplanotonometer to measure intraocular pressure(IOP), Ocular Response Analyzer(ORA) in order to determine corneal hysteresis (CH) and corneal resistance factor(CRF), ultrasonic pachimetry (Ocuscan) to measure central corneal thickness(CCT) and Humphrey visual field to determine mean deviation(MD), pattern standard deviation(PSD) and visual field index(VFI). The patients were divided into two groups: one group of diagnosed POAG patients and one control group of healthy individuals. Statistical analysis was performed using descriptive analyses and linear regression. Results: A considerable statistic correlation was found between CH and VFI both in the group of primary open angle glaucoma patients(r=0.52, P<0.0001), and the control group (r=0.22, p<0.04). Conclusions: The study shows a positive correlation, statistically significant, between corneal hysteresis and visual field index both in glaucoma patients and control subjects proving that a lower CH associates with a lower VFI. Ocular response analyzer can be considered a useful instrument in evaluation of primary open angle glaucoma patients. PMID- 29450317 TI - Complications of combined retinal and retinal pigment epithelium hamartoma involving the optic disc in a child, treated with Avastin - a review of the literature and case presentation. AB - We present a case of a 9 years old boy, followed up for 4 years, with bilateral combined pigmented epithelial and retinal hamartoma, complicated with recurrent vitreous hemorrhages in one eye and neovascular glaucoma and cataract in the other eye, treated with repeated intravitreal injections of Bevacizumab. A review of the literature suggested that such lesions may be symptomatic because of decreased vision, macular pucker, strabismus and vitreous hemorrhages. This particular compressive, bilateral form of hamartoma of the optic nerve has not previously been reported as a cause for such an ischemic syndrome, complicated with neovascular glaucoma and cataract. PMID- 29450318 TI - Ophthalmological implications of the chronic infections with the hepatitis C Virus. AB - Objectives. Report of a clinical case reuniting the dry eye syndrome in a severe form, the Mooren's ulcer and necrotizing anterior scleritis with inflammation, with bilateral affectation in the context of chronic infection with the hepatitis C virus. Methods. A female patient aged 66 diagnosed with chronic hepatitis with HCV, with ophthalmological antecedents of Mooren's ulcer and severe form of dry eye syndrome in both eyes, comes to the emergency unit with hypopyon corneal ulcer in the right eye, shortly afterwards developing necrotizing anterior scleritis with inflammation. The patient is administered treatment for chronic hepatitis C, following which the ARN-HCV viremia decreases without ocular exacerbations. When the viremia level increases again, two lesions indicating necrotizing anterior scleritis are observed in the left eye. The evolution is favourable with topical and systemic treatment with corticosteroids. Complicated cataract is surgically treated in the right eye and vitreous humour is collected during surgery. Results. Visual acuity increases in the right eye after the surgery, while antibodies-HCV are identified in the vitreous humour. Conclusions. Chronic infection with hepatitis C virus displays multiple extra-hepatic manifestations and the ophthalmological ones require a multidisciplinary approach from both the chronic diseases practitioner and the ophthalmologist. PMID- 29450319 TI - Upper eyelid abscess as a late complication of frontal sinus trauma. AB - The authors report a case of upper eyelid abscess in a 30 year old male that presented in the ophthalmology department with complains of recurrent eyelid pyosis, hyperaemia and swelling that started 2 months earlier and that did not ease to repeated courses of antibiotic therapy. The reported history of the patient revealed frontal sinus trauma that occurred 5 years before and that required surgical treatment (fixation with titan plaque and screws) with total healing and giving no further complains over the next years. The present cranial CT imaging showed intraorbital fat infiltration with displacement of one orbital arcade screw. Clinical findings showed normal ocular mobility. Antibiotic treatment and screw extraction through eyelid fistula improved the outcome but did not resolve the fistulous communication. Final management involved surgical removal of orbital arcade plaque and remaining screw and excision of fistula tract. The postoperative outcome was very good and the fistula remained closed but left the patient with an upper eyelid retraction which will require oculoplastic surgery in the future. PMID- 29450320 TI - Total retinal detachment occurring after minor head trauma. AB - The objective of this article is to present the case of a patient with a severe decrease of visual acuity that occurred after an apparently minor head injury. Following the investigations, the patient was diagnosed with rhegmatogenous retinal detachment that was triggered by a fall from the same level and which occurred on a background of lattice degeneration. In this case, a minor trauma caused a severe complication because the patient had a contributing factor for the complication. The patient was operated and the end result was satisfactory.

AB - Age related binocular vision disorders (age related strabismus) could include all types of spontaneous strabismus appearing along the lifetime, which are directly connected with the aging process. Neurological strabismus is excluded. Functional and structural changes related to the aging process can induce phoria decompensation, convergence insufficiency decompensation and new onset strabismus as distance esotropia or vertical strabismus induced by the sagging eye syndrome. MRI studies sustain the hypothesis of age related structural changes of extraocular muscles pulleys and their influence on the eye position and motility nominated as sagging eye. Age Related Distance Esotropia, Age Related Divergence Insufficiency Esotropia are probably different names for the same type of strabismus. All types of age related binocular disorders require treatment because of the accompanying diplopia. Prisms or/ and surgery can improve the patients' life quality by eliminating diplopia in primary position and main gazes. PMID- 29450324 TI - Chromovitrectomy. AB - The term "chromovitrectomy" has been coined to define the use of vital dyes in vitreoretinal surgery. The basic concept for the application of vital dyes during vitreoretinal surgery is to assist in highlighting preretinal membranes and tissues which are very thin and semitransparent and thus difficult to detect. Various dyes are currently being used in routine clinical procedures, however, the ideal staining agent has not yet been found. The vital dyes indocyanine green, infracyanine green, and brilliant blue stain the internal limiting membrane, trypan blue and triamcinolone acetonide help to visualize the epiretinal and vitreous membranes. New dyes with a better safety profile than the synthetic ones are important for optimizing the outcome of modern ophthalmic surgery and natural dyes, such as lutein, offer a potentially safer and more efficient method of identifying intraocular structures such as vitreous and ILM. Any dye, which is intravitreally injected has the potential to become toxic. PMID- 29450325 TI - New perspectives in retinal imaging - angio OCT. AB - In the last few years, structural and functional optical coherence tomography (OCT) technology has seen new and revolutionary developments. The most important of all is OCT angiography (Angio-OCT). Angio-OCT already plays an important role in clinical ophthalmology as a new, non invasive and dyeless diagnostic tool, which serves as an adjunct to, or even a replacement for fluorescein and indocyanine green (ICG) angiographies. Angio-OCT brings multiple technical and clinical improvements in the study of retinal diseases, glaucoma, and optic nerve disorders. It enables rapid, high-resolution, detailed images of large retinal vessels and capillary networks in seconds by using a strategy called "motion contrast", as opposed to revealing detailed images of large retinal vessels and capillary networks in seconds by using a strategy called "motion contrast" as opposed to the minutes required in conventional fluorescein angiography. These images are uniquely three-dimensional and allow an isolated study of individual capillary beds at different depths of the retina. PMID- 29450326 TI - Implication of gelatinases in retinoblastoma development. AB - The aim of this paper was to reveal the latest clinical and research findings regarding the implications of MMP2 and MMP9 matrix metalloproteinases in retinoblastoma development. The targets were finding better options for the therapeutic approach, considering the etiopathogeny and biology of this tumor. PMID- 29450327 TI - Common causes of red eye presenting in northern Iran. AB - AIM: This study aimed to determine the causes of red eye disease among patients of Mazandaran-Northern Iran. METHODS: This cross sectional study included 840 patients who referred to eye clinics with ocular complaints. A detailed history of patients was recorded and their eyes were examined. Then, pre designed checklists were completed by the researcher. RESULTS: The most common cause of red eye was conjunctivitis - 30% (252/ 840), foreign bodies 23.2%, trauma including penetrating or blunt 8.6%, respectively. There was a significant relationship between the red eye trauma, with acute onset and duration of less than a week (P=<0.0001). Diagnoses of red eye were conjunctivitis in 31.3% of the cases separately, viral causes (19.5%), allergic (7%) and bacterial (4%), foreign bodies 22.9%, pterygium 7%, and trauma 6.5%, respectively. CONCLUSION: In the current study, the most common causes of red eyes were conjunctivitis, foreign bodies, and trauma respectively. Red eye was more common in males than in females. An appropriate and proper training of risky factors of red eyes in the future could reduce the risk of serious visual problems. PMID- 29450328 TI - Diagnosis of non-exudative (DRY) age related macular degeneration by non-invasive photon-correlation spectroscopy. AB - PURPOSE: Photon-correlation spectroscopy (PCS) (quasi-elastic light scattering spectroscopy, dynamic light scattering spectroscopy) allows the non-invasively reveal of local dynamics and local heterogeneities of macromolecular systems. The capability of this technique to diagnose the retinal pathologies by in-vivo investigations of spatial anomalies of retinas displaying non-exudative senile macular degeneration was evaluated. Further, the potential use of the technique for the diagnosis of the macular degeneration was analyzed and displayed by the Receiver Operating Curve (ROC). METHODS: The maculae and the peripheral retina of 73 normal eyes and of 26 eyes afflicted by an early stage of non-exudative senile macular degeneration were characterized by time-correlation functions and analyzed in terms of characteristic decay times and apparent size distributions. RESULTS: The characteristics of the obtained time-correlation functions of the eyes afflicted with nonexudative macular degeneration and of normal eyes differed significantly, which could be referred to a significant change of the nano- and microstructure of the investigated pathologic maculas. CONCLUSIONS: Photon correlation spectroscopy is able to assess the macromolecular and microstructural aberrations in the macula afflicted by non-exudative, senile macular degeneration. It has been demonstrated that macromolecules of this disease show a characteristic abnormal behavior in the macula. PMID- 29450329 TI - "Off-label" use of intravitreal bevacizumab in non-ischemic macular edema secondary to retinal vein obstructions. AB - OBJECTIVE: To evaluate the safety and efficacy of intravitreal Bevacizumab in treatment of non-ischemic macular edema secondary to retinal vein obstruction (RVO). MATERIALS AND METHODS: A 2-year-retrospective study was performed on 26 patients hospitalized for non-ischemic macular edema secondary to RVO. All the patients underwent a complete ophthalmologic exam, with best corrected visual acuity (BCVA) testing, fundus photography, fluorescein angiography (FA) and macular thickness measurement by optical coherence tomography (OCT). Reevaluation was performed monthly for VA, OCT, and ophthalmoscopy and, at every 3 months, by FA. A standard protocol of 0.05 ml intravitreal Bevacizumab injection was applied. Further administrations were performed according to clinical evolution. RESULTS: The medium follow-up period was of 9,7 months (6-20 months). There were no significant complications following the procedure. The number of intravitreal Bevacizumab injections varied from 2-5/ patient. All the patients experienced an improvement in VA and a significant regression of macular edema. The smallest number of intravitreal Bevacizumab injections and the best visual prognosis were observed in cases with branch retinal vein obstruction (BRVO) and early presentation (p<0.05). CONCLUSIONS: As a pathogenic therapy, intravitreal Bevacizumab is a safe, repeatable procedure and it may be considered an effective and lasting treatment for non-ischemic macular edema secondary to RVO. Intravitreal Bevacizumab should be included in the therapeutic protocol of RVO, both for early and delayed presentations. Abbreviations: RVO = retinal vein obstruction, BRVO = branch retinal vein obstruction, CRVO = central retinal branch obstruction, BCVA = best corrected visual acuity, FA = fluorescein angiography, OCT = optical coherence tomography. PMID- 29450330 TI - Aflibercept efficacy in refractory choroidal neovascularization. AB - : The aim of the report is to evaluate the short-term efficacy and safety of aflibercept (EYLEA(r)) in patients with choroidal neovascularization (CNV) transformed into refractory during treatment with bevacizumab (AVASTIN (r)). METHODS: Clinical, morphological, and functional changes were retrospectively evaluated in cases with refractory CNVs to monthly 1.25 mg bevacizumab intravitreal injections (AVASTIN (r)) and switched to 3 monthly 2.0 mg intravitreal injections of aflibercept (EYLEA (r)). RESULTS: In this pilot evaluation, 8 cases of CNVs that become refractory to intravitreal treatment with 1.25 mg intravitreal bevacizumab (AVASTIN (r)), were switched to 2.0 mg intravitreal aflibercept (EYLEA (r)) and evaluated. The mean age of patients was 67.6 years (54-74 years). In 7 cases, CNV was associated to age related macular degeneration and in 1 case to angioid streaks. The mean number of previous intravitreal bevacizumab (AVASTIN(r)) administrations was 9.32 (7-12). In all cases, the last 3 intravitreal injections of bevacizumab were performed at an interval of maximum 6 weeks. The refractory status was confirmed by the lack of improvement or worsening of the clinical features as revealed by SD-OCT. A slowly anatomical improvement was noticed in 5 out of 8 cases (62.5%) since the first aflibercept administration. The anatomical improvement was stable after 3 monthly administrations. During the treatment, only 3 out of 5 cases (60%) showing anatomical improvement had a minor visual benefit (one line of VA gain). In 3 cases, the treatment change was unremarkable. No side effects were noticed. CONCLUSIONS: The anatomical improvement confirms previous reports regarding the efficacy and safety of aflibercept (EYLEA(r)) in some cases of CNV that became refractory during conventional anti-VEGF therapy. The improvement can be, at least partially, explained by the more complex features of aflibercept. Unfortunately, a minor visual benefit was noticed in a limited number of cases. PMID- 29450331 TI - Can patients with visual impairment follow a normal school? AB - AIM: To highlight the needs for socio-professional orientation of patients with visual impairment. MATERIAL AND METHODS: Prospective observational study on 69 patients (47 boys and 22 girls), with a mean age of 15,99+/-3,4235 years, evaluated in the Ophthalmology Clinic of "Sf. Spiridon" Hospital Iasi, in order to obtain a medical certificate. Clinical parameters: slit lamp examination, fundoscopy, visual acuity, intraocular pressure, orthoptic exam, ocular ultrasound, or corneal pachymetry (in selected cases). A questionnaire for the age group of 12-18 years was applied. Data were statistically analyzed by using the Student's t-test. RESULTS: Sixteen patients had ocular prosthesis or visual acuity 0 in one eye and 31 patients had a low vision. Patient's diagnosis: anterior segment diseases (23,18%), posterior segment diseases (52,17%), other diagnoses (24,63%). The pathology was congenital in 60,86% of the cases. 13,04% of the patients (3 school children and 6 students) asked for the integration into normal school/ university. Frequent answers: lack of special means of assistance in schools/ universities, need for additional schooling, people's reluctance which led to situations of ridicule, dependence on others to perform daily activities, need for professional help. CONCLUSIONS: Children with eye deficiencies can be scholarized in normal an educational system, according to the level of intelligence. Adolescents with eye disorders may attend University courses if proper aids are provided. Socio-professional orientation should be performed as early as possible to increase the quality of life in sighted patients. Aids for low-vision patients are insufficiently used in Romania. PMID- 29450332 TI - Corneal endothelial morphology and function after torsional and longitudinal ultrasound mode phacoemulsification. AB - PURPOSE: To study the endothelial cell morphology and corneal thickness changes after phacoemulsification by using the OZil torsional and longitudinal ultrasound techniques (Infiniti Vision System, Alcon Laboratories). SETTING: Department of Ophthalmology, Clinical Center, University of Debrecen, Debrecen, Hungary. METHODS: 52 patients with cataract were randomly assigned to longitudinal ultrasound and torsional mode group. All surgeries were performed through a 2.2 mm clear corneal incision, the method employed being divide and conquer. The endothelial morphometry such as cell density (ECD), mean cell area, coefficient of variation of cell area, and central corneal thickness were examined with specular microscopy (EM-1000, Tomey) preoperatively and 4, 8 weeks postoperatively. RESULTS: ECD values decreased significantly in both surgical groups (P < .001, repeated- mesures ANOVA), the postoperative endothelial cell loss was higher in the longitudinal ultrasound mode group (3.5% and 6.5%, at 4 and 8 weeks after surgery) than in the torsional group (3.3% and 5.5%, at 4 and 8 weeks after surgery), the difference not being significant between the two groups (P = .164 and P = .479, at 4 and 8 weeks after surgery, Mann-Whitney test). There was no statistically significant difference in any of the assessed parameters between the two surgical groups (P > .05). No significant correlation was found between the endothelial cell loss and the nucleus density. CONCLUSIONS: Both phacoemulsification techniques were safe and effective. The torsional handpiece performs oscillatory movements and delivers less energy into the eye than the longitudinal ultrasound technique, therefore providing more favorable energy and thermal safety profile. PMID- 29450333 TI - Finite element analysis on a medical implant. AB - Several studies have shown a tight connection between several ocular pathologies and an increased risk of hip fractures due to falling, especially among elderly patients. The total replacement of the hip joint is a major surgical intervention that aims to restore the function of the affected hip by various factors, such as arthritis, injures, and others. A corkscrew-like femoral stem was designed in order to preserve the bone stock and to prevent the occurrence of iatrogenic fractures during the hammering of the implant. In this paper, the finite element analysis for the proposed design was applied, considering different loads and three types of materials. A finite element analysis is a powerful tool to simulate, optimize, design, and select suitable materials for new medical implants. The results showed that the best scenario was for Ti6Al4V alloy, although Ti and 316L stainless steel had a reasonable high safety factor. PMID- 29450334 TI - Central retinal vein occlusion in a young adult Case report. AB - PURPOSE: To report the case of a 48-year-old man with unilateral central retinal vein occlusion. METHODS: The clinical, hematologic and hypercoagulability evaluations of the patient were thoroughly and specifically carried out. RESULTS: The central retinal vein occlusion was of nonischemic type and was associated with polyglobulia, hyperleukocytosis, hypercholesterolemia, multiple dental foci, and pulmonary sequelae of tuberculosis. CONCLUSIONS: When a patient less than 50 years of age experiences central retinal vein occlusion, other mechanisms, such as the hyperviscosity syndrome or the inflammatory condition (inflammation of the central retinal vein) should be specifically considered and accounted for. PMID- 29450335 TI - Secondary open-angle pigmentary glaucoma resulting from pseudophakia. Case report. AB - PURPOSE: To report the case of a 60-year-old man with a pseudophakia-related secondary open-angle pigmentary glaucoma without individual hereditary steroid susceptibility. METHODS: The clinical and functional evaluations of the patient were thoroughly and specifically carried out. RESULTS: The unilateral pseudophakic open-angle pigmentary glaucoma occurred in the context of rubbing of the haptics and optic of a posterior chamber intraocular lens implanted in the sulcus, against the posterior surface of the iris, with resultant pigment dispersion, trabecular inflammation, and aqueous outflow obstruction. CONCLUSIONS: Although the clinical picture of our case was very similar to that of pigmentary glaucoma, the distinction between the two conditions was still quite easy, considering that pigmentary glaucoma is a bilateral disorder predominantly affecting young myopic men with Krukenberg spindle and increased incidence of steroid responsiveness.

AB - Contact lenses are an attractive alternative for vision corrections. Their improvement can be achieved by optimizing the geometry, use of new materials, and application of high precision processing technologies. The optimized design can be obtained by computer-aided design, considering the principles of geometrical optics. Inventor Professional and other similar advanced 3D CAD software allows complex approaches, selection of suitable materials with better mechanical/ optical properties. This is useful for the preparation of the virtual design for 3D printing or CNC fabrication. A finite element analysis is also of interest for testing the best design/ material choice. In this paper, the finite element analysis for a tri-curve contact lens was applied. The selected materials were PMMA and polycarbonate. The applied compressive loads were in the range from 10 to 100MPa. Our results showed that the best scenario was for the polycarbonate, but PMMA also had a high safety factor. The maximum compression load with a reasonable safety factor (of 7-9 depending on materials) was 12MPa. PMID- 29450338 TI - Small eye - a small stump which can challenge and tilt a great surgery. AB - The small eye suggests an apparently robust anatomy with a more resistant sclera, good trabecular function, good uvea trophicity, a healthy retina, with a full papilla. The volume of these eyes is small. Usually, the volume of the eye is related to the sagittal diameter of the eye. However, the volume of a sphere varies with the third power of the radius of the sphere. These small eyes have a volume smaller than their sagittal diameter suggests. In this volume, highly decreased develop certain anatomical components without having to keep proportions (lens, choroid), and some have a continuous growing volume (lens). On long term, there is a balance inside these eyes despite a disproportion between their components. This internal disproportion inside the small eye can erupt through pressure differences between its structures: pupillary block, angle closure or a disproportionate response in case of typically uncomplicated surgery, which alters the apparent internal balance of these eyes. Seemingly simple surgeries, such as phacoemulsification or filtering surgery can trigger storm (storms occur by differences in atmospheric pressure) with the following characteristics: - intraocular "precipitation" in the form of uveal effusions, massive choroidal hemorrhage exudative retinal detachment, CME - breaks in anatomical barriers, lens posterior capsular tear - deviations courses: aqueous misdirection Surgical operations on these eyes are like a dangerous storm surfing, with risks, incidents, with unpredictable but great experience and courage request. PMID- 29450339 TI - Bevacizumab in the treatment of acute central/hemicentral retinal vein occlusions. AB - Even if bevacizumab is unlicensed, a majority of retina specialists still currently recommends it in retinal vein occlusion-related macular edema. For the first time, the results of our studies showed evidence suggesting that an early treatment administered immediately after the onset of venous occlusion, provided a significant and sustained improvement in visual acuity and foveal thickness, with inactive disease (dry retina and stable visual acuity for at least 6 months after the last injection) in most phakic patients with acute central/ hemicentral retinal vein occlusions, making this treatment option a rational and viable therapeutic strategy. Central/ hemicentral retinal vein occlusion has to be considered an ophthalmic emergency. The highlighting of the ocular conditions most frequently associated with central/ hemicentral retinal vein occlusion (ocular hypertension, primary open angle glaucoma, primary angle closure suspect, primary angle closure, and primary angle closure glaucoma) is mandatory. Regardless of the anti-vascular endothelial growth factor agents used (bevacizumab/ ranibizumab / aflibercept/), and regardless of the treatment approaches chosen (treat-and-extend/ pro re nata algorithm), the efficacy of therapy depends primarily on the precociousness of the therapy after the diagnosis of central/ hemicentral retinal vein occlusion. Any delay in the treatment will adversely influence the restoration of visual functions, which are difficult to correct even with subsequent treatment. PMID- 29450340 TI - Ocular surface - a complex and vulnerable adoptive environment for topical glaucoma treatment. AB - Ocular surface is a complex functional unit in which tissues so different as structure and function harmonize to produce a very short life (15-45 sec) film - tear film essential for the quality of the vision. With age, the ocular surface undergoes a physiological decline, often with a limitation of its functionality. Administration of topical glaucoma treatment itself constitutes a solicitation of the ocular surface and the nature of "accessories" included in this "drop glaucoma treatment", that might be the last straw which breaks the fragile balance or aggravates a previously nonexistent suffering subclinical symptomatology by opening and inducing reactions to treatment. Topical treatment in glaucoma could have the complex aspect of an adoption. Every adoption is a delicate and unpredictable phenomenon. Success does mean harmony and coexistence. For the adoption to succeed, one needs to know well the adoptive environment, the adopted element and the science and art to harmonize them together. PMID- 29450341 TI - Translating data and measurements from stratus to cirrus OCT in glaucoma patients and healthy subjects. AB - Aim: our study tried to find a mathematical conversion method of the measurements obtained in Time Domain (TD) OCT to Spectral Domain (SD) OCT. Material and method: A prospective randomized, double blind study that included 244 eyes, from 121 patients (normal subjects, glaucoma suspects, glaucoma), in whom we analyzed the retinal nerve fiber layer (RNFL) and the optic disc in the same session by using TD OCT (Stratus) and SD OCT (Cirrus), was performed. The means for RNFL thickness (overall value and per quadrants), neural area and cup/ disc (C/ D) ratio, were measured. Results: We found statistically significant differences between parameters measured in TD OCT and SD OCT (p<0.001). Powerful correlations were calculated between parameters measured with the two OCT machines. Data dispersion showed a linear relation between measurements. One can use the following mathematical equations for conversion: Mean RNFL (Cirrus) = 15.77 + 0.748 x Mean RNFL (Stratus) Mean neural area (Cirrus) = 0.508 + 0.388 x Mean neural area (Stratus) Mean C/ D ratio (Cirrus) = 0.157 + 0.792 x Mean C/ D (Stratus) Conclusions: data based on our calculated mathematical conversion equations can be converted into SD OCT. Therefore, we offered a useful tool for the long term monitoring of our patients although the initial measurements in TD OCT made comparisons for patients later measured with SD OCT impossible.

PMID- 29450342 TI - Epidemiology of ocular emergencies in Cluj ophthalmology clinic. AB - Objective. This study focused on the epidemiology of ocular diseases in the Eye Emergency Room. Methods. A cross-section retrospective study was performed in the Ophthalmology Clinic in Cluj-Napoca and included 11786 patients who presented to the Eye Emergency Room throughout the whole year, from January to December. Results. Every month, between 782 to 1189 patients with an average age of 39.54 years (+/-21.14) presented to the Eye Emergency Room. 250 were infants, under 1 year old. Six disease categories were followed: inflammation, trauma, vascular, tumor, glaucoma, and retinal-vitreal. Conjunctivitis and corneal foreign bodies accounted for almost half of the cases. Most of the conjunctival cultures revealed negative results. Conclusions. Consistent with the large number of patients included in this study, we considered the epidemiological data representative for our region. Male gender and youth represented the main risk factor for eye injury, while children remained the main group with conjunctivitis. PMID- 29450343 TI - Conjunctival autograft in pterygium treatment. AB - Pterygium is characterized by the thickening of the bulbar conjunctiva and the invasion of the cornea from the sclerocorneal limbus to the central portion of the cornea. Pterygium produces corneal deformation, which extends toward the central portion of the cornea. The visual disorders depend on the corneal extent. The treatment goal is the removal of the corneal and conjunctival portion of the pterygium and the coverage of the resulting conjunctival defect. The association of the pterygium surgical excision was assessed with conjunctival autograft. For this purpose, a retrospective study was performed on 68 patients and was extended over 7 years (2009-2015). Patients with recurrent pterygium were excluded. The time for corneal re-epithelization and for the pain and photophobia disappearance was followed. The incidence of recurrence was also observed. Pain levels were assessed by using a 10-point visual analog linear scale (VAS). The mean time for ocular pain and photophobia disappearance was of 48 hours. The mean pain score was 3.38 at 24 hours after surgery. Corneal re-epithelialization was achieved in 60 hours after surgery. Recurrence occurred in 6 patients. It was concluded that pterygium surgical excision with conjunctival autograft is effective in pterygium surgery. PMID- 29450344 TI - Risk factors and long term progression in open angle glaucoma patients. AB - Aim: Investigation of perimetric progression rate and associated risk factors in open angle glaucoma, in clinical practice. Methods: Retrospective study based on clinical charts reviews of patients with primary open angle glaucoma (POAG) being followed for > 5 years with >/ = 5 SITA Standard visual fields. Demographics, visual acuity (VA), central corneal thickness (CCT), intraocular pressure (IOP) and IOP variation, treatment (number of medications), visual fields and associated systemic pathologies were recorded. Patients were followed at every 3 6 months, when identical tests were performed. VF progression rate was calculated as slope of mean deviation (MD) over time by Glaucoma Progression Analysis software. Results: 121 eyes of 121 patients with POAG were included in the study and were followed for a mean period of 68.81 months (SD +/ - 31.7). The mean MD at start was -3.55 dB (SD +/ -5.19)., with a mean number of VF tests of 9.3+/ 2.9. Progression rate reached -0.21 +/ -0.1 db/ year. Mean IOP of all visits decreased over time from 18.20 mmHg to 16.53 mmHg (p<0.05). Systemic factors like positive history of hypertension reached statistical relevance in terms of increased risk for glaucoma progression, but only after age and sex were corrected. MD slope was explained in ANOVA univariate analysis, by the level of MD at baseline, IOP baseline, number of topical medications and CCT in a proportion equal to 71.7% (p=0.004). Conclusion: Rate of visual field changes in POAG was correlated and dependent on the baseline MD level, IOP at baseline, number of topical medications and a thin CCT. PMID- 29450345 TI - Vogt-Koyanagi-Harada syndrome Case report. AB - Vogt-Koyanagi-Harada syndrome is an uncommon multisystem inflammatory disorder characterized by panuveitis with serous retinal detachment and is often associated with neurologic and cutaneous manifestations including headache, hearing loss, vitiligo, and poliosis. The case of a 62-year-old female with diabetes mellitus and a history of primary open angle glaucoma (POAG) in both eyes, operated on the left eye two weeks prior to the presentation and under topical antiglaucomatous drops, was reported. She presented at the ophthalmological service for decreased visual acuity (VA) in both eyes. The slit lamp examination revealed keratic precipitates and posterior iris synechiae in both eyes and an ExPress aqueous shunt in the left eye. Inferior retinal detachment was observed on ocular fundus examination on both eyes. Intraocular pressure value was in normal range under antiglaucomatous drops (dorzolamid + timolol). The distinctiveness of this case was the association of the VKH syndrome with POAG and the inability to prolong the corticosteroid treatment, necessary in this case, due to the association of diabetes mellitus. PMID- 29450346 TI - Fulminant bilateral acute retinal necrosis after chickenpox - a case report. AB - : We present the case of a 34-year-old male, admitted for progressive bilateral loss of vision after a recent episode of chickenpox. Ophthalmological exam revealed bilateral acute retinal necrosis. As the patient was following a drug detoxification program, he was tested for HIV, HVB, HVC, and results highly positive. Immediate intravenous therapy with high doses of acyclovir and methylprednisolone was initiated, but the evolution was extremely severe resulting in necrotic retinal detachment. Surgery was performed in right eye, but no improvement of visual acuity was observed. CONCLUSIONS: The fulminant evolution of bilateral acute retinal necrosis and the lack of response to maximal intravenous therapy were clinical elements indicating coexistent immunosuppressive disease. Very severe acute retinal necrosis may occur in immunosuppressed patients, leading to blindness. PMID- 29450347 TI - Combined etiology for bilateral and simultaneous optic neuropathy in a patient with ciancobalamin deficit and hepatitis C treated with peg-interferon and ribavirin. AB - We report the case of a 53-year-old female patient who developed bilateral sudden visual acuity loss after 15 weeks from the initiation of Peg-Interferon and Ribavirin treatment for hepatitis C. Debut was simultaneous and asymmetric, reported in the morning, at awakening. No pain or other symptom was reported by the patient. Results. At presentation, visual acuity was 0.2 in RE and 3/ 50 in LE. Pupillary reflexes were sluggish and severe dyschromatopsia was documented in both eyes (Ishihara plates). Fundus examination revealed bilateral pale optic disc edema, more prominent in LE, with splinter hemorrhages in the RNFL around the optic disk. Visual field exam demonstrated severe defects in 3 quadrants of the RE, whereas in the LE, it was impossible to perform the investigation due to VA<0.1. Neurologic evaluation was normal; other possible causes of systemic vasculitis were excluded by negative lab tests. Acute inflammatory markers (fibrinogen and ESR) and mild pancytopenia were the only documented laboratory changes in this patient. Anamnesis cleared the traditional risk factors for conventional AION (hypertension, diabetes, ischemic heart disease, and hypercholesterolemia). Cranial and orbital CT scan and MRI findings were normal. Patient was withdrawn from the Interferon and Ribavirin treatment and was administered methyl prednisolone pulse therapy (1g/ day) for 3 days, continued with oral Prednisone (60 mg/ day) tapered slowly for over 12 weeks. VA increased to 0.8 during treatment in the RE, but visual recovery in the LE was not as spectacular (0.16) as in the fellow eye. Modified latencies and amplitudes in evoked visual potentials examination during 4 months time emphasized bilateral optic atrophy. Optic nerve sufferance was amplified by a low level of vitamin B12, detected by chance at the last eye visit. Due to the general condition, dietary supplementation was not possible. Conclusion. A case of a patient with bilateral and simultaneous NAION caused by IFN and Ribavirin treatment for hepatitis C, who was also vitamin B12 deficient, was analyzed. Therefore, a combined etiology for optic atrophy was explained. PMID- 29450348 TI - An atypical case of post surgery macular edema -Case report. AB - The article presents an atypical case of bilateral postoperative macular edema, with an unfavorable outcome, however considering the treatment options and ways to prevent this complication. PMID- 29450349 TI - Atopic keratoconjunctivitis with corneal ulcer. Case report. AB - Purpose: To report the case of a 14-year-old male patient, with bilateral atopic keratoconjunctivitis with corneal ulcer. Methods: The patient complained of bilateral red, itchy eyes, decreased vision, photophobia, difficulty opening the eyelids upon awakening, palpebral edema, excessive tearing, along with yellowish mucous discharge. He had a two-year history of chronic blepharitis and recurrent episodes of conjunctivitis that were treated with Tobramycin and corticosteroid eye drops over the years. The patient's past medical history was significant for atopic dermatitis (AD) and he had a family history for atopy. At the eye exam: his best-corrected visual acuity at the initial presentation was 0.2 in the right eye and 1.0 in the left eye. The following elements were found upon the slit lamp biomicroscopy: Eyelids - +4 palpebral edema (pseudoptosis), Dennie-Morgan fold and Herthoge's sign were both present, tylosis; Conjunctiva - hyperaemia, cobblestone appearance of the tarsal papillae in both eyes, +2 chemosis; Cornea - corneal edema with a 8 mm * 4 mm epithelial defect in the inferior part of the cornea, covered partially by the lied, that stained positive with fluorescein dyes. Using the Evaluation Signs Severity for Allergic Ocular Diseases, a diagnosis of bilateral atopic keratoconjunctivitis with a grade 3 status for the right eye and a grade 2 status, was made. It was decided that he should be administered Olopatadine hydrochloride and Sodium cromoglicate eye drops, along with Moxifloxacin and steroid eye drops. The microbiological exam tested positive for staphylococcus aureus, and, based on the sensitivity pattern, Chloramphenicol eye drops had to be added to the treatment. After 2 weeks, his symptoms diminished, pain was significantly relieved and inflammation was markedly reduced, but the corneal ulcer persisted. In order to prevent corneal perforations, amniotic membrane transplantation (AMT) was used to promote epithelialization. Results: A month later, the epithelial defect healed smoothly in an underlying vascular stromal scar and the visual acuity improved to 0.4 RE. Conclusions: This case demonstrated the role of patient history and close clinical obser-vation in the diagnosis of AKC. As this case showed, the use of topic medication along with amniotic membrane transplantation (AMT) was successful in the treatment of atopic keratoconjunctivitis and secondary staphylococcal aureus keratitis. PMID- 29450350 TI - Romania - UEMS, EBO. PMID- 29450351 TI - Glaucoma after chemical burns and radiation. AB - Glaucoma after chemical burns represents a posttraumatic glaucoma, usually open angle glaucoma. It is a frequent complication of chemical burns, especially with alkali and it can appear in the acute stage or as a late complication. Because of the complications and scars, the treatment is very difficult. Topical treatment is based on AC inhibitors, beta-blockers, alpha2-agonists. Trabeculectomy, shunts, cyclophotocoagulation, and cryotherapy are the solutions in the late stages. Glaucoma after irradiation is a closing-angle secondary glaucoma. The risk factors such as the radiation dose and the volume of the radiated structure are important in the appearance and evolution of this type of glaucoma. Topical treatment is usually ineffective, the preferable options being laser and surgical treatments. Although it is not a frequently seen pathology, it is important to know how to diagnose and treat this type of glaucoma. There are various options available for treatment, but choosing one is difficult because of the possible complications. PMID- 29450352 TI - Ethical issues in advertising and promotion of medical units. AB - Bioethics tries to define the medical activity and any other related activity needed to maintain the function of a health institution, through the development of principles and moral values. Bioethics is quite broad and has a background that combines various disciplines such as medicine, philosophy, law, sociology, and theology. Advertising and promotion are part of the strategy aimed at developing and maintaining relationships with the targeted audience (patients). To regulate this activity, it was necessary to develop ethical rules of healthcare marketing. The content of promotional messages must be truthful and should not create unjustified expectations. The doctor or the healthcare unit must be able to provide the services claimed in the advertisement. From an ethical point of view, marketing communication should be more consistent with reality, even if its purpose is to shed light on more attractive issues. In this context, the categories and groups vulnerable to certain content of the advertising message should be mentioned. A patient with a serious suffering will be easily influenced and will tend to trust any promise easily, with the desire to heal. Ethically, the information presented must not alter the reality and should not give false hopes to patients. Those responsible for marketing in the healthcare field must keep in mind the ethics code of the medical profession, must maintain an honest marketing communication, which does not create inaccurate expectations, must not denigrate other colleagues, and must use a message whose content should respect the dignity of the profession. PMID- 29450354 TI - Subliminal perception of complex visual stimuli. AB - Rationale: Unconscious perception of various sensory modalities is an active subject of research though its function and effect on behavior is uncertain. Objective: The present study tried to assess if unconscious visual perception could occur with more complex visual stimuli than previously utilized. Methods and Results: Videos containing slideshows of indifferent complex images with interspersed frames of interest of various durations were presented to 24 healthy volunteers. The perception of the stimulus was evaluated with a forced-choice questionnaire while awareness was quantified by self-assessment with a modified awareness scale annexed to each question with 4 categories of awareness. At values of 16.66 ms of stimulus duration, conscious awareness was not possible and answers regarding the stimulus were random. At 50 ms, nonrandom answers were coupled with no self-reported awareness suggesting unconscious perception of the stimulus. At larger durations of stimulus presentation, significantly correct answers were coupled with a certain conscious awareness. Discussion: At values of 50 ms, unconscious perception is possible even with complex visual stimuli. Further studies are recommended with a focus on a range of interest of stimulus duration between 50 to 16.66 ms. PMID- 29450353 TI - The importance of assessing corneal biomechanical properties in glaucoma patients care - a review. AB - Purpose: to familiarize the public with the role of corneal biomechanics in glaucoma patient management. Methods: Ocular Response Analyzer (ORA) is the only device that measures in vivo corneal biomechanics. Recent studies regarding "corneal biomechanics and glaucoma" were reviewed and the obtained data were compared in order to present a better understanding of the corneal biomechanical properties involvement in glaucoma care. Results: According to the studies reviewed, in primary open angle glaucoma (POAG) the mean corneal hysteresis (CH) and the corneal resistance factor (CRF) were approximately 2 mmHg lower than in normal eyes. In ocular hypertension (OH), the mean CH was about 1mmHg higher than in POAG patients and 1mmHg lower than in the control group, while the mean CRF was about 2mmHg higher than in POAG and 1mmHg higher than in the control group. Regarding the normal tension glaucoma (NTG), there were studies that showed that the mean CH and CRF were approximately 1mmHg lower than in POAG and studies that showed similar values between the POAG and NTG groups. The mean CH did not differ much between POAG and angle closure glaucoma (ACG), being lower than in normal individuals, while CRF appeared to be higher in the ACG than in normal individuals. Concerning congenital glaucoma (CG), both CH and CRF were about 2mmHg lower than in normal eyes. Conclusions: Corneal biomechanics influenced the IOP measurement and have been proven to be of a great significance in glaucoma patients regardless of the central corneal thickness (CCT). Lower values of CH and CRF could suggest an alteration in the corneal response associated to glaucoma. PMID- 29450355 TI - Survey on retrobulbar blood flow in glaucomatous optic neuropathy (normotensive and hypertensive). AB - The aim of this study was to analyze the possible differences between retrobulbar blood flows in normotensive glaucomatous optic neuropathy patients versus patients with hypertensive glaucomatous optic neuropathy, with intraocular pressure controlled treatment. All the patients in the study group were subjected to a color Doppler echography of retrobulbar vessels. Afterwards, systolic and diastolic blood velocities were measured in both eyes in ophthalmic artery (OA), central retinal artery (CRA) and posterior ciliary arteries (PCA). The device calculated the Resistivity index Pourcelot (RI) automatically. PMID- 29450356 TI - Color Doppler imaging of the retrobulbar circulation in progressive glaucoma optic neuropathy. AB - It is known that elevated intraocular pressure (IOP) is the primary risk factor for glaucoma. Recently, more and more evidences have shown that the vascular deficit also plays an important role in the pathogenesis and progressions of glaucomatous optic neuropathy. This issue is backed up by glaucomatous optic neuropathy (GON) cases drug compensated in which the progression of the disease in one or both eyes is ascertained despite a normal and relatively constant IOP. The present study evaluated the hemodynamic parameters in the retrobulbar circulation in patients with progressive glaucomatous optic neuropathy in one eye, who received compensated medication. The hemodynamic parameters (PSV, EDV, IR) were measured by using color Doppler ultrasound and progression was evaluated by a repeated automated perimetry. The obtained values were statistically analyzed and compared with those obtained for the stable eye. PMID- 29450357 TI - Difference of refraction values between standard autorefractometry and Plusoptix. AB - Aim: Comparison between the objective refraction measurement results determined with Topcon KR-8900 standard autorefractometer and Plusoptix A09 photo refractometer in children. Material and methods: A prospective transversal study was performed in the Department of Ophthalmology of "Sf. Spiridon" Hospital in Iasi on 90 eyes of 45 pediatric patients, with a mean age of 8,82 +/- 3,52 years, examined with noncycloplegic measurements provided by Plusoptix A09 and cycloplegic and noncycloplegic measurements provided by Topcon KR-8900 standard autorefractometer. The clinical parameters compared were the following: spherical equivalent (SE), spherical and cylindrical values, and cylinder axis. Astigmatism was recorded and evaluated with the cylindrical value on minus after transposition. The statistical calculation was performed with paired t-tests and Pearson's correlation analysis. All the data were analyzed with SPSS statistical package 19 (SPSS for Windows, Chicago, IL). Results: Plusoptix A09 noncycloplegic values were relatively equal between the eyes, with slightly lower values compared to noncycloplegic auto refractometry. Mean (+/- SD) measurements provided by Plusoptix AO9 were the following: spherical power 1.11 +/- 1.52, cylindrical power 0.80 +/- 0.80, and spherical equivalent 0.71 +/- 1.39. The noncycloplegic auto refractometer mean (+/- SD) measurements were spherical power 1.12 +/- 1.63, cylindrical power 0.79 +/- 0,77 and spherical equivalent 0.71 +/- 1.58. The cycloplegic auto refractometer mean (+/- SD) measurements were spherical power 2.08 +/- 1.95, cylindrical power 0,82 +/- 0.85 and spherical equivalent 1.68 +/- 1.87. 32% of the eyes were hyperopic, 2.67% were myopic, 65.33% had astigmatism, and 30% eyes had amblyopia. Conclusions: Noncycloplegic objective refraction values were similar with those determined by autorefractometry. Plusoptix had an important role in the ophthalmological screening, but did not detect higher refractive errors, justifying the cycloplegic autorefractometry. PMID- 29450358 TI - Recurrent inverted papilloma of paranasal sinus presenting as acute proptosis. AB - Objective. To describe the course of events that followed from the time of the diagnosis to the management of a rare case of recurrent inverted papilloma presenting as an acute proptosis. Methods. A seventy-year-old diabetic female patient presented with a painful left eye proptosis for 15 days. She had a history of resection of inverted papilloma of paranasal sinus followed by radiotherapy for eight years before. The examination revealed a 23 mm proptosis, with restricted ocular movements, corneal oedema, funnel shaped anterior chamber, and total retinal detachment with a complete visual loss. The lobulated fixed hard mass was palpable circumferentially but more in the inferior orbital compartment. The transconjunctival incisional biopsy showed features of highly undifferentiated cytology. The lid sparing exenteration was done under general anesthesia with cosmetic reconstruction. Results. Immunohistochemistry of exenterated mass was doubtfully suggestive of a small cell tumor. However, histopathology confirmed features of rhabdomyosarcoma. Conclusion. The present case study revealed rhabdomyosarcoma cytology presenting as an association inverted papilloma. Abbreviations : IP = Inverted papilloma, PNS = Paranasal sinus, SCC = Squamous cell carcinoma, IOP = Intraocular pressure, CT = Computed tomography. PMID- 29450359 TI - Complicated corneal ulcer. Case report. AB - Corneal ulcers are considered an ophthalmologic emergency because of their potential to permanently impair vision or perforate the eye. The therapeutic management includes medical therapy and in case of failure, surgical care such as amniotic membrane transplantation. We present the case of a 76-year-old male, admitted for sudden visual loss in the left eye, associated with ocular pain, tearing, and photophobia. The patient was diagnosed with superficial ulcerative keratitis with hypopyon and acute exogenous anterior uveitis for which he underwent medical treatment, both general and topic, with a good evolution during a month. After a month, the patient presented with the corneal ulcer perforated. Surgery was performed in the left eye by covering the ocular surface with an amniotic membrane using the Motowa's sandwich technique. After one year, the same patient was successfully operated for cataract removal and posterior chamber intraocular lens implantation in the left eye. PMID- 29450360 TI - Choroidal melanoma suspect. Conservative treatment and evolution. Case report. AB - We present the case of a 42-year-old female who presented to our clinic for phosphenes in the left eye, occurring along with eye movement. A diagnosis of choroidal melanoma suspect was made. Due to the patient's profile, young, active woman, surgeon, and the limited therapeutic options in Romania, a conservative treatment and brachytherapy were chosen, which were successfully performed abroad. The patient has been followed-up, so far, for five years after the procedure, with spectacular results. PMID- 29450361 TI - Pseudo-Foster Kennedy Syndrome - a case report. AB - Objective: To report a case of Pseudo-Foster Kennedy (PFK) syndrome and describe its clinical and paraclinical particularities, as well as the diagnostic difficulties and established treatment. Methods: The case of a 60-year-old male patient with sudden, painless visual impairment in the left eye (LE), and a medical history of old optic nerve atrophy in his right eye (RE) was described. Results: The diagnosis of nonarteritic anterior ischemic optic neuropathy (NAION) was established based on the medical history, local and general clinical and paraclinical examination, and temporal artery biopsy. Conclusions: Although there is no current generally accepted treatment for NAION, a correct diagnosis and supportive treatment may contribute to the improvement in visual acuity (VA), improvement that in this case remained stable for 6 months after the onset. The patient is still being monitored and no relapses have been noted. PMID- 29450362 TI - Can subtenon methylprednisolone acetate be a choice for the acute non-arteritic ischemic optic neuropathy treatment? AB - Nonarteritic ischemic optic neuropathy is characterized by sudden, painless, unilateral vision loss. A case of an acute NAION patient who was treated with subtenon methyl prednisolone acetate was presented. The patient, a 65-year-old male, presented vision loss for two days. The total ophthalmologic examination, fundus photography, and automated perimetry were applied to the patient before and after 1, 3, and 6 months from injection. The visual acuity increased from 0,1 to 0,3 in the first month and to 0,7 at the last visit, the visual field defect being mostly improved. This case showed that 40 mg of subtenon methyl prednisolone acetate injection was an effective and safe treatment method for acute NAION. However, a large randomized controlled trial is needed to assess the efficacy of subtenon methyl prednisolone acetate as a treatment for NAION. PMID- 29450364 TI - Matrix regenerative therapy. AB - The extracellular matrix (ECM) is responsible for many of the cell behavior processes, including cell proliferation and growth, survival, change in cell shape, migration, and differentiation. The most important component of the ECM is heparan sulfate (HS), because it insures the storage of many cell communication proteins, necessary for the continuous and identical renewal of cells and thus for tissue regeneration. Regenerating agents (RGTA(r)) are bioengineered structural analogues of heparan sulfate glycosaminoglycans that replace the degraded endogenous HS of the ECM. In the ophthalmological field, RGTA(r) represents an innovative approach for the improvement of the ocular surface wound healing and matrix remodeling and plays a role in controlling and regulating the wound healing process in various ocular diseases. PMID- 29450365 TI - Uveitis-Glaucoma-Hyphaema Syndrome. General review. AB - Uveitis-Glaucoma-Hyphaema Syndrome (UGH syndrome, or "Ellingson" Syndrome) is a rare condition caused by the mechanical trauma of an intraocular lens malpositioned over adjacent structures (iris, ciliary body, iridocorneal angle), leading to a spectrum of iris transillumination defects, microhyphaemas and pigmentary dispersion, concomitant with elevated intraocular pressure (IOP). UGH Syndrome can also be characterized by chronic inflammation, secondary iris neovascularization, cystoid macular edema (CME). The fundamental step in the pathogenesis of UGH syndrome appears to arise from repetitive mechanical iris trauma by a malpositioned or subluxed IOL. These patients have uncomplicated cataract implants and return for episodes of blurry vision weeks to months after surgery. This may be accompanied by pain, photophobia, erythropsia, anterior uveitis, hyphaema along with raised intraocular pressure. A careful history and examination, as well as appropriate investigations can confirm the diagnostic. Treatment options are IOL Explantation exchange, topical and systemic medication, and cyclophotocoagulation, the placement of a Capsular Tension Ring to redistribute zonular tension and Anti-vascular endothelial growth factor (anti VEGF) Therapy. PMID- 29450366 TI - Is Laser Assisted Capsulotomy better than standard CCC? AB - Objectives: To compare the safety and intraoperative difficulties of two capsulorhexis techniques for white intumescent cataract: Femtolaser-assisted capsulorhexis and manual capsulorhexis performed in 2-3 stages, with the Utrata forceps. Materials and methods: A prospective comparative study that included 28 eyes divided into 2 equal groups in which capsulorhexis was performed by using the 2 methods. In the first group, the capsulorhexis was executed by using LenSx Femtolaser. In the second group, an Utrata forceps was used to perform a manual 2 3 steps capsulorhexis as follows: a small 2-3 mm capsulorhexis was performed after the staining of the anterior capsule with Trypan Blue along with a good pressurization with viscoelastic substance. The liquefied cortex was aspirated, followed by the enlargement of the capsulorhexis. In some cases, the enlargement was made after IOL implantation. Results: In the Femtolaser group, the capsule was completely detached in 13 cases and only in one case, the capsule had a few bridges which detached easily, without endangering the capsulorhexis integrity. Its size was 4,9 mm in all cases. In the group in which capsulorhexis was performed with the Utrata forceps in 2-3 stages, this was complete, circular and relatively well centered in all cases, but the size varied between 4,5 and 5,5 mm. Conclusions: Femtosecond laser-assisted capsulorhexis was round, well centered and of a desired size of 4,9 mm. The manual capsulorhexis with the Utrata forceps depends on the surgeon's skill and experience and requires a good local anesthesia, the coloring of the anterior capsule with Tripan Blue, using a large quantity of cohesive viscoelastic substances and sometimes using micro incision forceps for helpful maneuvers. The size and centering of the capsulorhexis are not always identical with the intended ones. PMID- 29450367 TI - One year refractive outcomes of Femtosecond-LASIK in mild, moderate and high myopia. AB - Purpose: To evaluate the safety, efficacy, predictability and stability for a cohort of myopic eyes treated by Femtosecond-LASIK procedure. Methods: 60 eyes (36 patients) with different degrees of myopia that underwent refractive surgery by using the Femtosecond-LASIK technique were prospectively evaluated for 12 months. The mean preoperative spherical equivalent value was -3.827 +/- 1.410 diopters (D) (range: -8.125 to -1.375 D). VisuMax(r) femtosecond laser was used for cutting the corneal flap and then the Mel80(r) excimer laser for the stromal ablation. Results: Mean age was 30.80 +/- 5.745 years (range: 21 to 46 years) with 75% female patients. Postoperative spherical equivalent at 12 months was within +/-0.25 D of emmetropia in 90% of the eyes and within +/-0.50 D of emmetropia in 100% of the eyes. All the eyes achieved an uncorrected distance visual acuity (UDVA) of 1.0 (decimal scale). No eye lost lines of preoperative corrected distance visual acuity (CDVA). No major intraoperative or postoperative complications were encountered. Conclusions: Femtosecond-LASIK seems to be a suitable option for the correction of mild, moderate, and high myopia, as the procedure showed to be safe, effective, and predictable for the treatment of myopic refractive errors. PMID- 29450368 TI - Topical administration of Metamizole and its implications on vascular reactivity in Wistar rats- Experimental research. AB - Aim: The aim of this paper was to describe the possible implications of topical (ocular) administration of Metamizole on vascular reactivity of the iris in Wistar rats. No other study regarding its topical use was found. Methods: Male adult Wistar rats were anaesthetized with Ketamine 100 mg /kg body weight - injected intraperitoneally - while maintaining spontaneous respiration and the blink reflex. After selecting the area of interest (long posterior ciliary artery - LPCA), manual adjustments of the image magnitude, clarity, and brightness were made, and the experiment began. The image recording lasted 10 minutes. Results: Metamizole induced a slight vasoconstriction that started with the initial moment for all the doses used. After the topical administration of Metamizole, we did not observe an increase of the vascular diameter of LPCA in a dose dependent manner. The saline solution used as a negative control did not modify the vessel diameter. Conclusions: Metamizole (dipyrone) is a non-opioid drug, which is commonly used in human and veterinary medicine. It is the most popular first-line analgesic in various populations. In some cases, this agent is still incorrectly classified as a non-steroidal anti-inflammatory drug. The high analgesic efficacy of metamizole, as well as its spasmolytic effect, makes it a very important pharmaceutical agent that could be used in the therapy of various eye disorders in humans and in animals.

AB - Objective: To evaluate the short-term changes in Schirmer I test (ST) after pars plana vitrectomy and to compare the results between 23 gauge and 20 gauge vitrectomy surgeries. Methods: 42 patients who underwent pars plana vitrectomy for posterior segment diseases were included in this prospective, non-randomized, comparative study. The choice of sclerotomy gauge was at the surgeons' discretion. ST values were recorded before and at 1 and 3 months after vitrectomy. Results: 20 patients in 23 gauge and 22 patients in 20-gauge group with a mean age of 59.9 +/- 13.5 years were included. The mean preoperative ST values decreased significantly in both groups at 1 and 3 months after surgery (all P < 0.01). The ST values in the fellow eyes were the same, at baseline and during the follow up (P > 0.05). At 3 months visit, 15 eyes (35.7%) had abnormal ST measurements. There was no statistically significant difference in the changes in the ST measurements between the two groups at one month (P = 0.7), however, 3 months after surgery, the mean decrease in the ST measurements was significantly higher in the 20 gauge group (P = 0.03). At 3 months, 4 eyes in the 23 gauge group (20%) and 11 eyes in the 20 gauge group (50%) had abnormal ST measurements (P = 0.05). Conclusions: Although both 20 and 23-gauge vitrectomy decrease the ST measurements postoperatively, the value is less affected by the 23-gauge vitrectomy. PMID- 29450370 TI - Terson's Syndrome - case report. AB - Terson's Syndrome is represented by a vitreous, retrohyaloid, retinal, or subretinal hemorrhage occurring consequent to an acute intracranial hemorrhage or elevated intracranial pressure. The outcome may include a complete clearing of the blood and the restoration of VA or persistent hemorrhage. This report presents the case of a 43-year-old woman who underwent bilateral surgery for a persistent vitreous hemorrhage and a hematoma underneath the internal limiting membrane in the left eye. The event followed shortly after a subarachnoid hemorrhage due to the rupture of a posterior communicating artery aneurism. Vitrectomy was performed in both eyes, together with the peeling of the internal limiting membrane in the left eye, followed by a bilateral good outcome. PMID- 29450371 TI - Necrotizing retinitis of multifactorial etiology. AB - Introduction. We present the case of a 73-year-old woman with osteoporosis, who presented to the emergency room with a sudden vision loss and ocular pain in the right eye, which appeared two days before. The patient mentioned loss of appetite, weight loss for three months and low fever for two weeks. Materials and methods. Among the ophthalmological findings, the most important were panuveitis, and large confluent necrotic areas in the peripheral retina. The patient was diagnosed with RE Panuveitis and acute necrotizing retinitis. Results. Blood exams showed leukocytosis and monocytosis, thrombocytosis and anemia. Further investigations showed high levels of Cytomegalovirus (CMV) anti IgG and Herpes Simplex (HS) type 1 virus anti IgM, urinary infection, and secondary hepatic cytolysis. The CT and MRI of the thorax and abdomen showed no sign of neoplastic disease, and no explanation for the CMV infection was found. The patient received general corticotherapy and antiviral therapy, and, after one month, RE BCVA was 20/ 30. Particularity of the case. Acute necrotizing retinitis in an old patient with CMV and HSV type 1, associated with secondary hepatic cytolysis, without any other immunosuppressive disease and very good outcome. PMID- 29450372 TI - Penetrating corneal wound with traumatic cataract and intraocular foreign body case report. AB - Open globe injuries complicated with the presence of an intraocular foreign body mostly affect young males and represent a vision threatening condition. We presented the case of a 48-year-old male who presented to our emergency service due to ocular pain and blurred vision in his right eye. A metallic foreign body situated between 1 and 12 o'clock, near the corneoscleral limbus, that perforated the cornea, the iris, the anterior capsule of the lens and the lens, was detected at the slit-lamp examination. We decided to immediately remove the foreign body that was approximately 20 mm long. The following day, traumatic cataract had already developed, so we performed cataract extraction. Despite the dimensions of the intraocular foreign body, the retina was attached and there were no sign of retinal tears or vitreous haemorrhage. The proper management in this case led to good results in spite of the dimensions of the intraocular foreign body.

AB - The paper presents the case of a 57-year-old male patient who complained of slow progressive loss of visual acuity. Anamnesis revealed he was a heavy drinker and he was previously diagnosed with a pancreatic cancer, observed on the MRI. The clinical examination revealed ocular features that made the diagnosis difficult. Initially, it seemed to be a case of narrow angle glaucoma but further ocular examinations revealed macular thinning. PMID- 29450374 TI - Intraocular ossification. Case report. AB - Objective: To report a case of intraocular ossification, describe its particularities and review some of the pathogenesis theories. Methods: We described the case of a 31-year-old woman with a history of perforating trauma ten years before, who presented in our clinic for right eye pain. The patient wanted a cosmetic improvement so an evisceration was proposed. An intraocular hard yellowish mass, which had a histopathological examination, was found intraoperatively. Results: We diagnosed the case as an intraocular ossification, based on the medical history and histopathological specimen examination, which proved to be an ossified structure. Conclusions: In spite of a rare occurrence, our case emphasized the theory that trauma and subsequent neurogenic inflammation could lead to osseous metaplasia.

AB - Ocular posterior pole modification are a pathological manifestation in complicated pregnancies, especially when pregnancy induced hypertension is present (PIH), as well as in preeclampsia (PE) or eclampsia. Nonetheless, as the pregnancy evolves, the possibility for an aggravated evolution with HELLP syndrome, disseminated intravascular coagulation, and idiopathic thrombocytopenic purpura may have an ocular manifestation that, mainly, implies a loss of visual field or acuity, that, left unattended, may constitute a permanent impairment. Pregestational conditions like pituitary adenoma or genetic pedigree for complement factor H gene (1q31.1) single nucleotide mutations could lead to central serous chorioretinopathy or retinal detachment with severe, ischemic, central cilioretinal artery or vein occlusion and optic nerve atrophy. Furthermore, although subtle in many cases, any new visual symptoms during pregnancy should constitute an alarming factor for obstetrical reevaluation and ophthalmological approach in order to preserve the mother's quality of life.

PMID- 29450380 TI - CAN Optical Coherence Tomography redefine amblyopia? AB - Introduction: For many years, amblyopia was regarded as a disorder of the visual system in which an organic cause could not be identified. Optical Coherence Tomography opens new horizons in understanding the etiopathology of amblyopia and seems to highlight morphologic anomalies in the retina of the amblyopic eye. Purpose: The objective of this paper is to analyze the macular thickness, optic nerve changes, and choroidal thickness found in patients diagnosed with amblyopia based on trials reported in the literature. Material and methods: This study analyzes 30 clinical trials regarding amblyopia evaluation with Optical Coherence Tomography. The research articles analyzed were published between 2006 - 2016 and were identified on PubMed database. Results: 19 research studies focused on macular and nerve optic changes, 7 on choroidal changes and 6 on retinal changes after occlusion. The results were discussed according to the type of amblyopia, alteration of macular thickness, optic nerve changes, ganglion cell layer changes, and alteration of choroidal thickness. Conclusions: The results are of great variability, and it seems that macula and choroid involvement is more frequently suggested compared with optic nerve involvement.

PMID- 29450381 TI - Insights in the treatment of congenital nasolacrimal duct obstruction. AB - Introduction: Congenital nasolacrimal duct obstruction is one of the most common causes of epiphora in newborns and the main cause of this condition is the persistence of Hasner membrane. Several treatment options are available, like conservative treatment, probing, irrigation, or more complex techniques. Objective: The objective of this paper is to discuss the efficiency of different treatment options addressing congenital nasolacrimal duct obstruction based on trials reported in literature. Methods: Clinical trials were identified on PubMed. The results were discussed regarding patient age, type of treatment and efficiency of the treatment. Results: 41 trials were reviewed. The rate of resolution according to different treatment options was the following: conservative treatment 14.2-96%, probing 78-100%, irrigation 33-100%, silicon tube intubation 62-100%, inferior turbinate fracture 54.7-97%, balloon dacryocystoplasty 77%, endoscopic intranasal surgery 92.72%, and dacryocystorhinostomy 88.2-93.33%. Conclusions: The first choice in uncomplicated cases should be a conservative treatment, which can be followed until the age of 1 year, while in complicated cases other solutions should be considered.

PMID- 29450382 TI - IRIDEX MicroPulse P3: innovative cyclophotocoagulation. AB - Purpose: To present the new IRIDEX MicroPulse P3 (MP3) technology in patients with refractory glaucoma and our preliminary results at 1 week and 1 month postoperatively. Methods: IRIDEX MP3 laser cyclophotocoagulation was performed in 7 eyes of 7 patients under retrobulbar anaesthesia with lidocaine 2% in the operating room. Each eye received two treatments of 80-90s over the superior and inferior hemisphere, avoiding the temporal- and nasal-most clock hours. 810nm IRIDEX MP3 was set to 31,3% duty cycle (0,5ms treatment pulse followed by 1,1 ms of rest). Postoperative topical steroids were prescribed for 1 week. Results: Mean IOP decrease at 1 week was 60,3% and 33,4% at 1 month, with a mean topical hypotensive treatment reduction of 0,71 therapeutic agents. The procedure was safe in all cases and effective in 71% of the patients. Neovascular glaucoma patients registered high IOP levels 1 month postoperatively in spite of medical and MP3 laser treatment. BCVA remained unchanged after undertaking the laser procedure. No significant inflammation, discomfort, or pain was reported. There were no complications such as hypotony, phthisis bulbi, and macular edema. Conclusions: IRIDEX MP3 represents an innovation in cyclophotocoagulation. It is non-destructive, repeatable, non-invasive, with a high safety profile. A mean IOP decrease of 33,4% was registered at 1 month. Patient comfort and recovery are favorable. Long-term results will prove its efficacy in the future. PMID- 29450383 TI - Eyesight quality and Computer Vision Syndrome. AB - The aim of the study was to analyze the effects that gadgets have on eyesight quality. A prospective observational study was conducted from January to July 2016, on 60 people who were divided into two groups: Group 1 - 30 middle school pupils with a mean age of 11.9 +/- 1.86 and Group 2 - 30 patients evaluated in the Ophthalmology Clinic, "Sf. Spiridon" Hospital, Iasi, with a mean age of 21.36 +/- 7.16 years. The clinical parameters observed were the following: visual acuity (VA), objective refraction, binocular vision (BV), fusional amplitude (FA), Schirmer's test. A questionnaire was also distributed, which contained 8 questions that highlighted the gadget's impact on the eyesight. The use of different gadgets, such as computer, laptops, mobile phones or other displays become part of our everyday life and people experience a variety of ocular symptoms or vision problems related to these. Computer Vision Syndrome (CVS) represents a group of visual and extraocular symptoms associated with sustained use of visual display terminals. Headache, blurred vision, and ocular congestion are the most frequent manifestations determined by the long time use of gadgets. Mobile phones and laptops are the most frequently used gadgets. People who use gadgets for a long time have a sustained effort for accommodation. A small amount of refractive errors (especially myopic shift) was objectively recorded by various studies on near work. Dry eye syndrome could also be identified, and an improvement of visual comfort could be observed after the instillation of artificial tears drops. Computer Vision Syndrome is still under-diagnosed, and people should be made aware of the bad effects the prolonged use of gadgets has on eyesight. PMID- 29450384 TI - Plateau Iris - Therapeutic options and functional results after treatment. AB - We present the therapeutic options and functional results in patients with plateau iris (syndrome or configuration) in consecutive case series. Material and method: Our study included newly diagnosed patients with acute angle closure by "plateau iris" (configuration or syndrome), between June 2016 and April 2017. Series of 8 consecutive patients met the inclusion criteria, all being females. All the patients underwent an individualized treatment according to the underlying mechanism and evolution. Functional results (visual acuity, IOP, topical medication) were reported in the current paper. Results: For 10 months, we diagnosed 14 eyes, from 9 patients with acute angle closure by Plateau Iris, distributed as it follows: 6 eyes with closed angle glaucoma (optic disk and visual field changes), 8 eyes with plateau iris syndrome and 2 eyes with plateau iris configuration. 7/ 8 patients were misdiagnosed with primary open angle glaucoma, whereas only one patient had the correct diagnosis of closed angle glaucoma and underwent peripheral laser iridotomy. As treatment options in our study, we recommended and performed argon laser peripheral iridoplasty + iridotomy in 10/ 14 eyes, cataract lens was extracted in 4 eyes and then replaced with PC-IOL, whereas 2 eyes required a filtering anti-glaucoma surgery (trabeculectomy + PI). 2 eyes from the same patient could not be treated as intended as the patient refused the treatment. In this unique case, Pilocarpine (4%) was temporarily indicated. Conclusion: Plateau iris represents a diagnostic trap, but based on a thorough gonioscopic examination and a good patient history, the right diagnosis can be made, all along with a correct therapeutic approach.

AB - Introduction. Eales disease is an idiopathic peripheral vascular occlusive disease characterized by inflammation, ischemia, and retinal neovascularization and is hallmarked by recurrent vitreous hemorrhages and vision loss. Case report. We present a case of a 48-year-old female with recurrent floaters and decreased vision in her right eye. The onset of symptoms was in 2007 when a diagnose of retinal vasculitis was made. She had no accompanying systemic signs and symptoms and no history of ocular trauma or previous tuberculosis infection. The eye condition was managed only with intermittent focal laser treatment, because the general treatment with steroids was not efficient and poorly tolerated. After the laser treatment, the visual acuity completely recovered and there was no recurrence of vitreous hemorrhage. The case particularity was the unilaterality after 9 years from the onset. PMID- 29450391 TI - Citicoline - a neuroprotector with proven effects on glaucomatous disease. AB - Citicoline is the generic name of cytidine-5'-diphosphocholine (CDP-choline), an endogenous compound that is able to increase the levels of neurotransmitters in the central nervous system by interacting with the synthesis of cellular membranes phospholipids, especially phosphatidylcholine. Exogenous Citicoline, administered by ingestion or injection, is hydrolyzed and dephosphorylated in order to form cytidine and choline, which resynthesize CDP-choline inside brain cells. It has proven neuroprotective effects in Alzheimer disease, stroke, and Parkinson's disease, as well as in glaucoma and amblyopia. Citicoline acts as a neuroprotector for those patients with progressive glaucomatous disease in spite of well-controlled intraocular pressure. The purpose of this review was to outline the main features of Citicoline and the evidences of its effect in glaucoma. PMID- 29450392 TI - Glaucoma after penetrating keratoplasty. AB - Penetrating keratoplasty is a surgical intervention that despite the progress of surgical techniques and of postoperative treatment continues to have numerous complications. Many of them, such as graft rejection, significant astigmatism, cystoid macular edema, or cataract lead to important limitations of the visual function. Glaucoma is possibly the most dangerous complication following PK, leading to loss of the visual potential of the eye due to irreversible damage to the optic nerve. Identifying the risk factors permits an attentive follow-up and rapid treatment of the postoperative IOP rises. Maybe the most important is that preexisting glaucoma should be rightly diagnosed and controlled before PK, medically or, if necessary, surgically.

PMID- 29450393 TI - Management of diplopia. AB - Diplopia (seeing double) is an ophthalmologic complaint found mainly in elder patients. It can have both ocular and neurological causes. A careful history and clinical examination must detail the type of diplopia (monocular/ binocular), onset, and progression, associated and relieving factors. In case of monocular diplopia, refraction and biomicroscopic examination of the ocular media are mandatory. The cause of ocular misalignment for binocular diplopia must be determined and life-threatening conditions (such as posterior communicating artery aneurysm) must imply an immediate treatment. Management and treatment is always according to the specific cause of diplopia. PMID- 29450395 TI - Investigating the perception of Romanian adults on ophthalmology services from an experiential marketing perspective. AB - Nowadays, we live in a world in which we are daily bombed by hundreds of advertisements. Specialists have to discover other channels or embed attractive elements in the advertisements' messages to cut through the clutter and catch the consumers' attention. The evolution of the concept of service has changed from the commercial status to determining a lifestyle. Buying a service has led to a change in the consumer behavior. Consumers want to buy services that dazzle their senses, touch their hearts, and stimulate their minds, not as before, excellent or satisfying. Ophthalmology is the medical specialty that is the most oriented toward outpatient care, as hospitalization is required only in a small percentage of cases. The objective of this case study was to investigate the perception of Romanian adult consumers on ophthalmology services from an experiential marketing perspective, by using the Focus Group method. Ophthalmology requires a wide range of skills due to the diversity of consumers who demand specialized consultations. Experiential marketing is a valuable strategy that ophthalmologic organizations may use to target specific consumers. The purpose of this case study was to identify the perceptions of Romanian adults on experiential marketing campaigns and determine the degree to which these campaigns influenced their decisions of buying an ophthalmologic service. Using a snowball sampling technique we have sent a filter questionnaire to 40 people on the internet. The filter questionnaire consisted of questions about wearing eyeglasses, the period of wearing them, the last ophthalmologic consultation, the type of ophthalmologic clinic they were going to, age and education. The respondents revealed there is almost no visibility on promoting services even if there is an upsurge of organizations offering this type of health service in the Romanian ophthalmology sector. PMID- 29450396 TI - Transnasal endoscopic assisted dacryocystorhinostomy. AB - Transnasal endoscopic dacryocystorhinostomy is a good alternative for external DCR. It is considered a safe and efficient technique with successful results, comparable or even better than the external technique. Advanced knowledge of the endoscopic anatomy and the lacrimal system is necessary to perform the procedure safely, and to obtain good surgical outcomes. The aim of the paper is to analyze the changes of the endoscopic technique and to improve it. The transnasal endoscopic dacryocystorhinostomy surgical technique is described in a "step by step" manner. Also the surgical technologies that can be used for this intervention are presented, focusing on the cold instruments. PMID- 29450394 TI - Update on retinal vascular caliber. AB - Retinal vessels are the only blood vessels that can be viewed directly, in vivo, repetitively and non-invasively. Retinal vessel caliber is influenced by physiological (age, sex, race, blood pressure, blood glucose, body mass index) and pathological (atherosclerosis, dyslipidemia, smoking) determinants. There are studies on large population groups that demonstrate the associations between retinal vasculature and subclinical or clinical changes in systemic diseases (hypertension, diabetes, stroke, renal or cardiac diseases). The assessment of retinal vessels can provide information about the pathophysiology of many diseases, but it also has a direct applicability in clinic, being used as a screening method that predicts the risk of their occurrence. PMID- 29450397 TI - Transnasal endoscopic orbital decompression. AB - Transnasal endoscopic orbital decompression is a viable alternative for external orbital decompression. Today, it can be performed due to the great development of endoscopic technology and specific endoscopic surgical instruments. It requires strong anatomic knowledge and skilled hands. We present our experience with endoscopic orbital decompression focusing on the surgical technique used in our department. The surgical maneuvers must be firm and gentle protecting the local risk elements and respecting the orbital content. PMID- 29450398 TI - Cataract surgery outcome in patients with non-glaucomatous pseudoexfoliation. AB - Aim. To study the outcome of cataract surgery in eyes with pseudoexfoliation without signs of glaucoma. Methods. This prospective study was done over nine months on patients with pseudoexfoliation undergoing small incision cataract surgery. Only patients with normal intraocular pressure (Central Corneal Thickness Corrected), normal cup disc ratio and open angles were included. Patients on anti-glaucoma medication were excluded. Patients underwent surgery performed by a single senior surgeon. Intraoperative and postoperative day (POD) 1 findings were noted. Results. The mean age of the patients was 61.60 years +/ - 10.21 years. Males were 46% (n=16). Right eye was operated upon in 60% of the cases (n=21). The mean pupil dilation was 5.1 mm +/ - 1.47 mm. The postoperative day 1 visual acuity of the patients was logMar 1.02 +/- 0.64 and the mean POD 1 intraocular pressure was noted to be 26.23 mmHg +/ - 11.40 mmHg. Five cases had a zonular dialysis intraoperatively due to weak zonules. 11 cases had high anterior chamber reaction of 2+ or more. Four cases had unavoidable sphincter tears and two cases had iridodialysis superiorly during nucleus delivery. Conclusions. Intraoperative complications should be anticipated in patients with pseudoexfoliation even without glaucomatous changes due to poor pupillary dilation and zonular weakness. First postoperative day visual acuity in pseudoexfoliation patients undergoing cataract surgery was found to be low due to severe anterior chamber inflammation causing elevated intraocular pressure and corneal edema.

PMID- 29450399 TI - Functional results of cataract surgery in the treatment of phacomorphic glaucoma. AB - Purpose. Analysis of functional outcome and complications reported in patients diagnosed with phacomorphic glaucoma, in which phacoemulsification or extracapsular extraction of the lens was performed. Methods. The retrospective study included 38 eyes diagnosed with phacomorphic glaucoma. In 25 cases, group 1, the lens was removed by phacoemulsification and in 13 cases, group 2, by extracapsular extraction. Intraocular pressure, visual acuity, and anterior chamber depth were evaluated preoperative and postoperative. The incidence of intra and postoperative complications was analyzed. The minimum follow-up period was 12 months. Results. The mean IOP decreased from the preoperative value of 38.4 +/ - 11.3 mmHg to 13.5 +/ - 3.4 mmHg in group 1 and 11.5 +/ - 3.2 mmHg in group 2. Persistent corneal edema was observed in 32% patients from group 1 and 23% of the patients from group 2. The inflammatory reaction of anterior chamber prevailed in patients from group 2 (46.1%). ACD modified from the preoperative mean of 1.3 +/- 0.5 mm to 2.3 +/- 0.2 mm in both groups. At the end of follow-up in both groups, the average BCVA was 0.6. 18.42% of the cases required long-term topical hypotensive therapy. Conclusions. Both phacoemulsification and extracapsular extraction were safe and effective procedures in the treatment of phacomorphic glaucoma, ensuring a rapid functional recovery and a satisfactory long-term IOP control. Although the rate of immediate postoperative complications and the final functional outcome were better in patients treated with phacoemulsification, not all the cases could be subjected to this type of surgery. PMID- 29450400 TI - Incidence of ocular hypertension after intravitreal injection of anti-VEGF agents in the treatment of neovascular AMD. AB - Purpose. The assessment of the incidence of ocular hypertension over a period of 1 year in patients treated with multiple intravitreal injections of anti-VEGF agents for neovascular AMD. Methods. The study comprised 58 eyes diagnosed with neovascular age-related macular degeneration and receiving PRN intravitreal treatment with anti-VEGF agents (bevacizumab or aflibercept). The follow-up period was 1 year. Intraocular pressure was measured by using the Goldmann applanation tonometry before the intravitreal injection, at 24 hours after the administration of the anti-VEGF agent and at 1 and 4 weeks. Patients diagnosed with glaucoma or who underwent ophthalmic surgery were excluded. Results. The patients received an average of 7.54 intravitreal injections. The mean baseline intraocular pressure was 15.3 mm Hg; 19.8 mm Hg at 24 hours; 17,4 mmHg at 1 week and 14.8 mmHg at 4 weeks after the administration of the anti-VEGF agent. 4 patients required long-term topical hypotensive treatment. Raised intraocular pressure was related to increased frequency of treatment. At 1 year follow up, an average difference of 2.1 mmHg compared to baseline was registered in the cases that have received more than 6 intravitreal injections. By comparison, in the cases treated with a reduced number of doses of intravitreal anti VEGF agent, the difference from baseline was 0,9 mmHg. There were no significant differences in mean IOP depending on the anti VEGF (bevacizumab or aflibercept) agent used. Conclusions. Intravitreal treatment with anti VEGF agents produces a transient increase in intraocular pressure, predominantly immediately following administration, without causing long-term increased values. PMID- 29450401 TI - Non-parametric tests in detecting glaucoma progression. AB - Automated perimetry still represents the gold standard in long term glaucoma monitoring. On a daily practice basis, glaucoma progression analysis could be difficult due to the long time needed to detect, confirm, and quantify the progression rate. Moreover, "trend" and "event" analysis require a good theoretical basis to perform and interpret. Aim of study was to present an alternative method to conventional Glaucoma Progression Analysis (Humphrey Visual Field Analyzer, Carl Zeiss(r) Inc.) applied for the early detection of glaucoma progression. Such an "event" analysis orients the clinician in a fast manner on the progression profile in glaucoma patients and might adapt the follow up visits accordingly. Method and material: 41 eyes from 41 patients with open angle glaucoma were studied in a longitudinal manner, over a 24 months' time interval from diagnosis. Results: in the GPA analysis, a positive "event" (progression) was detected in 11/ 41 eyes (26.82%). Non-parametric analysis confirmed progression in all GPA cases, and additionally found 8 more eyes with positive progression (46.34% studied eyes). Mc Nemar concordance analysis between tests was good and relevant (kappa index k=0.596, p=0.000), with positive correlation (r=0.652, p=0.008). In conclusion, NPA tends to overestimate the number of progression cases in a cohort, but it can easily orient the clinician on the profile of the followed patients. In the first years, the GPA analysis can be highly inaccurate, but there is a great need to detect which patients are at significant risk for vision loss (fast progressors). Yet, combining the two methods of detection of glaucoma progression, the practitioners might direct their selected interest and attention towards observing a larger than expected number of patients who are at risk for vision loss over time due to glaucoma, but not necessarily in a fast manner. PMID- 29450402 TI - Modeling the consumer's perception of experiential marketing in the Romanian private ophthalmologic services. AB - Introduction. The importance of experience in marketing grew, as the concept itself is very personal and difficult to measure. Experience turns out to be complicated but once placed in a context it gets significant features. As the health care competitive environment increases, marketers are looking for new and effective methods of engaging consumers by using experiential marketing strategies. Moreover, little is known about the consumers' perceptions related to ophthalmologic services. Aim. The objective of this paper was to measure the consumer's perception of experiential marketing in the Romanian private ophthalmologic services by using structural equation modeling. Materials and Methods. The Experiential Marketing model consisted of the following components: Sense Experience, Feel Experience, Think Experience, Act Experience and Relate Experience as well as the consequences of applying Experiential Marketing in the form of willingness to purchase a service, generating word-of-mouth communication and building consumer loyalty. The sampling method was non-probabilistic, using the snowball technique and the sample was made up of 190 people who wore eyeglasses for more than 3 years. The instrument for data collection was a self administered questionnaire, which consisted of 2 parts: the first section contained several demographic questions and the second section encompassed closed end questions related to the perception of private ophthalmologic services from an experiential marketing perspective. All the second section questions were measured on a 5-point Likert scale ranging from 1 with Strongly Disagree to 5 to Strongly Agree. The data analysis was conducted in SPSS and the structural equation modeling was performed in WarpPLS version 6.0. Findings. There were 71.05% respondents, who appreciated the application of experiential marketing in private ophthalmologic services, followed by 18.95%, who were confused. The demographic profile of respondents encompassed the following features: females with the ages between 36 and 45, from the rural area and with a middle level of education, their private ophthalmologic consultation frequency was at every 3 months and they also declared having a stable physician. Going further with the analysis, 89.63% of the respondents admitted they were willing to buy a private ophthalmologic service based on the experiential marketing application strategies. The design of a model containing both the constituent elements of the experimental marketing and its consequences in ophthalmologic services was conducted by modeling with structural equations in WarpPLS version 6.0 software. Thus, the validity of the model was assessed with the Cronbach's alpha coefficients, Composite reliability values, as well as with the Average Variance Extracted coefficients, and the fitness of the model was determined by using the ARS, APC, and AVIF values, respectively. According to the beta coefficients and levels of statistical significance (p<0.05), some hypotheses have been rejected or negative relationships have been established between dependent and independent variables. Conclusions. Sense experience had a negative impact on WOM and consumer loyalty, Think Experience had a negative influence on the WOM, Relate Experience had a negative impact on consumer Loyalty, as well as Relate Experience had a negative impact on willingness to purchase an ophthalmologic service. In contrast, the following positive relationships were established: Feel Experience established a positive relationship with WOM and consumer loyalty, Think Experience presented a positive impact both on consumer loyalty and on willingness to purchase an ophthalmologic service, Act Experience presented a positive impact on WOM and willingness to purchase and last, willingness to purchase an ophthalmologic service presented a positive influence on consumer loyalty and WOM. However, managers in Ophthalmology can successfully use experimental marketing strategies if they promote a story, meaning a life experience.

AB - Juvenile xanthogranuloma (JXG) is a benign histiocytic skin disorder mainly encountered during infancy and childhood. Although with multiple potential localizations, less than 1% of the cases exhibit ocular manifestations. Some of these might lead to serious complications, specifically, secondary glaucoma that can result in severe and blinding eye disease. The aim of the present case report was to demonstrate typical clinical features, emphasize the difficulties attributed when managing these patients and literature review. We present the case of 4 months old female baby with spontaneous hyphema and secondary unilateral glaucoma due to ocular JXG. The natural history and treatment of the condition were extremely difficult to handle due to multiple opinions in histopathology related to other severe conditions that resembled with the lesions detected in this case: myelomonocytic leukemia and Langerhans cell histiocytosis. Although a minority of patients with JXG have ocular involvement, recognition of this condition is important because a treatment delay can lead to serious complications, such as glaucoma and spontaneous hyphema, as in our case. A thorough differential diagnosis represents the key to a proper management plan in these patients, both on short and long term. "Triple disease" defined as JXG plus neurofibromatosis type 1 (NF-1) and juvenile chronic myelogenous leukemia (JCML) has been reported, but it was not confirmed in our patient.

AB - Deep brain stimulation (DBS) is a neurosurgical technique, which consists of continuous delivery of an electrical pulse through chronically implanted electrodes connected to a neurostimulator, programmable in amplitude, pulse width, frequency, and stimulation channel. DBS is a promising treatment option for addressing severe and drug-resistant movement disorders. The success of DBS therapy is a combination of surgical implantation techniques, device technology, and clinical programming strategies. Changes in device settings require highly trained and experienced clinicians to achieve maximal therapeutic benefit for each targeted symptom, and optimization of stimulation parameters can take many visits. Thus, the development of innovative DBS technologies that can optimize the clinical implementation of DBS will lead to wider scale utilization. This review aims to present engineering approaches that have the potential to improve clinical outcomes of DBS, focusing on the development novel temporal patterns, innovative electrode designs, computational models to guide stimulation, closed loop DBS, and remote programming. PMID- 29450405 TI - Building with intent: technologies and principles for engineering mammalian cell based therapies to sense and respond. AB - The engineering of cells as programmable devices has enabled therapeutic strategies that could not otherwise be achieved. Such strategies include recapitulating and enhancing native cellular functions and composing novel functions. These novel functions may be composed using both natural and engineered biological components, with the latter exemplified by the development of synthetic receptor and signal transduction systems. Recent advances in implementing these approaches include the treatment of cancer, where the most clinical progress has been made to date, and the treatment of diabetes. Principles for engineering cell-based therapies that are safe and effective are increasingly needed and beginning to emerge, and will be essential in the development of this new class of therapeutics. PMID- 29450406 TI - Chemical Modification of the siRNA Seed Region Suppresses Off-Target Effects by Steric Hindrance to Base-Pairing with Targets. AB - Chemical modifications of 2'-O-methyl (2'-OMe) and locked nucleic acid (LNA) of the nucleotides in the seed region (positions 2-8) of the small interfering RNA (siRNA) guide strand significantly reduced seed-matched (SM) off-target effects. The siRNA with 2'-OMe modifications inhibited the expression of a completely matched (CM) target gene, whereas that with LNA modifications did not inhibit the expression of the CM target. By computational predictions of conformational changes of siRNA by these modifications, we revealed that both modifications in the siRNA seed region reduce SM off-target effects by steric hindrance to base pairing with target transcripts but LNA modifications also disturb the association of the siRNA guide strand with the Argonaute (AGO) protein by altering RNA conformation. Thus, chemical modifications of the siRNA guide strand, which alter steric conformation to disturb base-pairing with target transcripts but do not disturb the association with the AGO protein, may successfully suppress off-target effects without substantial loss of RNA silencing activity. PMID- 29450407 TI - Changes in the Cardiac GHSR1a-Ghrelin System Correlate With Myocardial Dysfunction in Diabetic Cardiomyopathy in Mice. AB - Ghrelin and its receptor, the growth hormone secretagogue receptor 1a (GHSR1a), are present in cardiac tissue. Activation of GHSR1a by ghrelin promotes cardiomyocyte contractility and survival, and changes in myocardial GHSR1a and circulating ghrelin track with end-stage heart failure, leading to the hypothesis that GHSR1a is a biomarker for heart failure. We hypothesized that GHSR1a could also be a biomarker for diabetic cardiomyopathy (DCM). We used two models of streptozotocin (STZ)-induced DCM: group 1, adult mice treated with 35 mg/kg STZ for 3 days; and group 2, neonatal mice treated with 70 mg/kg STZ at days 2 and 5 after birth. In group 1, mild fasting hyperglycemia (11 mM) was first detected 8 weeks after the last injection, and in group 2, severe fasting hyperglycemia (20 mM) was first detected 1 to 3 weeks after the last injection. In group 1, left ventricular function was slightly impaired as measured by echocardiography, and Western blot analysis showed a significant decrease in myocardial GHSR1a. In group 2, GHSR1a levels were also decreased as assessed by Cy5-ghrelin(1-19) fluorescence microscopy, and there was a significant negative correlation between GHSR1a levels and glucose tolerance. There were significant positive correlations between GHSR1a and ghrelin and between GHSR1a and sarcoplasmic reticulum Ca2+ ATPase 2a (SERCA2a), a marker for contractility, but not between GHSR1a and B type natriuretic peptide, a marker for heart failure. We conclude that the subclinical stage of DCM is accompanied by alterations in the myocardial ghrelin GHSR1a system, suggesting the possibility of a biomarker for DCM. PMID- 29450408 TI - Effect of Arginase-1 Inhibition on the Incidence of Autoimmune Diabetes in NOD Mice. AB - Metabolism of the amino acid L-arginine is implicated in many physiological and pathophysiological processes including autoimmune conditions such as type 1 diabetes (T1D). Alternate arginine metabolism through the citrulline-nitric oxide (NO) or the ornithine pathways can lead to proinflammatory or immune regulatory effects, respectively. In this report, we blocked the arginine-ornithine metabolic pathway by inhibiting the enzyme arginase-1 with Nomega-hydroxy-nor arginine (nor-NOHA) to make arginine more available to the alternate citrulline pathway for augmented NO production and increased incidence of autoimmune T1D in female non-obese diabetic (NOD) mice. Unexpectedly, mice receiving nor-NOHA did not develop diabetes although increased NO production is proinflammatory and expected to increase diabetes incidence. These results warrant further studies of the mechanism of action of nor-NOHA, and highlight its potential as a therapeutic agent for the treatment or prevention of T1D. PMID- 29450410 TI - Catalyst-free one step synthesis of large area vertically stacked N-doped graphene-boron nitride heterostructures from biomass source. AB - A procedure for the one-step preparation of films of few-layer N-doped graphene on top of nanometric hexagonal boron nitride sheets ((N)graphene/h-BN) based on the pyrolysis at 900 degrees C under an inert atmosphere of a film of chitosan containing about 20 wt% of ammonium borate salt as a precursor is reported. During the pyrolysis a spontaneous segregation of (N)graphene and boron nitride layers takes place. The films were characterized by optical microscopy that shows a thin graphene overlayer covering the boron nitride layer, the latter showing characteristic cracks, and by XPS measurements at different monitoring angles from 0 degrees to 50 degrees where an increase in the proportion of C vs. B and N was observed. The resulting (N)graphene/h-BN films were also characterized by Raman, HRTEM, SEM, FIB-SEM and AFM. The thickness of the (N)graphene and h-BN layers can be controlled by varying the concentration of precursors and the spin coating rate and is typically below 5 nm. Electrical conductivity measurements using microelectrodes can cause the burning of the graphene layer at high intensities, while lower intensities show that (N)graphene/h-BN films behave as capacitors in the range of positive voltages.

AB - Metrics of regional myocardial function can detect the onset of cardiovascular disease, evaluate the response to therapy, and provide mechanistic insight into cardiac dysfunction. Knowledge of local myocardial microstructure is necessary to distinguish between isotropic and anisotropic contributions of local deformation and to quantify myofiber kinematics, a microstructurally anchored measure of cardiac function. Using a computational model we combine in vivo cardiac displacement and diffusion tensor data to evaluate pointwise the deformation gradient tensor and isotropic and anisotropic deformation invariants. In discussing the imaging methods and the model construction, we identify potential improvements to increase measurement accuracy. We conclude by demonstrating the applicability of our method to compute myofiber strain in five healthy volunteers.

AB - The nutritional values and phytochemical composition of young shoots of wild Asparagus stipularis Forssk. from Tunisia were determined in this study. The antioxidant (tested by four different in vitro assays) and antiproliferative properties (against human tumour cell lines) of aqueous and hydroalcoholic extracts of the young shoots were also investigated. The obtained results indicated that the young shoots are a potential source of valuable nutrients and dietary fiber, and their hydroalcoholic extract showed marked antioxidant and antiproliferative activities in all tested assays. The major phenolic compound, characterized by using a high-performance liquid chromatograph coupled with diode array and mass spectrometer detectors, in both extracts was diferuloyl glycerol. Our results reinforce the interest in recovering the traditional culinary uses of this wild plant, with potential functional properties, which can be included in the modern diet as an alternative to the variety of vegetables normally used. PMID- 29450412 TI - Clinically approved liposomal nanomedicines: lessons learned from the biomolecular corona. AB - Nowadays, liposomes are the most successful drug delivery systems with a dozen drug products available in the clinic. Grafting poly-(ethylene glycol) (PEG) onto the liposome surface prevents protein binding thus prolonging blood circulation, while synthetic modification of the terminal PEG molecule with ligands (e.g. monoclonal antibodies and peptides) should promote selective accumulation in the tumor region with respect to healthy tissues. However, despite big efforts, advances have not outgrown the development stage and just a few targeted liposomal drugs are commercially available. The latest studies have clarified that following exposure to physiological environments liposomes are covered by a biomolecular corona (BC). Main factors shaping the BC are the liposomes' physicochemical properties (i.e. size, surface charge and lipid composition), the biological fluid (e.g. plasma of healthy volunteers vs. plasma of cancer patients) and environmental factors (e.g. temperature). Combining the most recent evidence reported in the literature, herein we suggest that the liposome-BC could act as a personalized "endogenous trigger" affecting off-target interactions and controlling the indication for disease of clinically approved formulations. In this Opinion paper, we suggest that a better understanding of the liposome-BC together with improvements in mapping corona proteins will open the fascinating possibility to manipulate the BC by liposome design. This is not an easy task, but it could represent a turning point in the development of novel liposome-based targeting strategies for personalized nanomedicines.

AB - Micro-scale hydrogel particles, known as microgels, are used in industry to control the rheology of numerous different products, and are also used in experimental research to study the origins of jamming and glassy behavior in soft sphere model systems. At the macro-scale, the rheological behaviour of densely packed microgels has been thoroughly characterized; at the particle-scale, careful investigations of jamming, yielding, and glassy-dynamics have been performed through experiment, theory, and simulation. However, at low packing fractions near jamming, the connection between microgel yielding phenomena and the physics of their constituent polymer chains has not been made. Here we investigate whether basic polymer physics scaling laws predict macroscopic yielding behaviours in packed microgels. We measure the yield stress and cross over shear-rate in several different anionic microgel systems prepared at packing fractions just above the jamming transition, and show that our data can be predicted from classic polyelectrolyte physics scaling laws. We find that diffusive relaxations of microgel deformation during particle re-arrangements can predict the shear-rate at which microgels yield, and the elastic stress associated with these particle deformations predict the yield stress. PMID- 29450414 TI - First-principles method for calculating the rate constants of internal-conversion and intersystem-crossing transitions. AB - A method for calculating the rate constants for internal-conversion (kIC) and intersystem-crossing (kISC) processes within the adiabatic and Franck-Condon (FC) approximations is proposed. The applicability of the method is demonstrated by calculation of kIC and kISC for a set of organic and organometallic compounds with experimentally known spectroscopic properties. The studied molecules were pyrromethene-567 dye, psoralene, hetero[8]circulenes, free-base porphyrin, naphthalene, and larger polyacenes. We also studied fac-Alq3 and fac-Ir(ppy)3, which are important molecules in organic light emitting diodes (OLEDs). The excitation energies were calculated at the multi-configuration quasi-degenerate second-order perturbation theory (XMC-QDPT2) level, which is found to yield excitation energies in good agreement with experimental data. Spin-orbit coupling matrix elements, non-adiabatic coupling matrix elements, Huang-Rhys factors, and vibrational energies were calculated at the time-dependent density functional theory (TDDFT) and complete active space self-consistent field (CASSCF) levels. The computed fluorescence quantum yields for the pyrromethene-567 dye, psoralene, hetero[8]circulenes, fac-Alq3 and fac-Ir(ppy)3 agree well with experimental data, whereas for the free-base porphyrin, naphthalene, and the polyacenes, the obtained quantum yields significantly differ from the experimental values, because the FC and adiabatic approximations are not accurate for these molecules.

AB - A soft-oxometalate (SOM) based on Mo and V i.e. {MoV9} in their highest oxidation state reduces CO2 to HCOOH selectively in water. Catalysis initiates without the use of any photosensitizer and solvent water acts as the sacrificial electron donor which gets oxidized to generate oxygen. Electrons and protons released in this process reduce CO2 to HCOOH. PMID- 29450416 TI - A G-quadruplex motif at the 3' end of sgRNAs improves CRISPR-Cas9 based genome editing efficiency. AB - Originating as a component of prokaryotic adaptive immunity, the type II CRISPR/Cas9 system has been repurposed for targeted genome editing in various organisms. Although Cas9 can bind and cleave DNA efficiently under in vitro conditions, its activity inside a cell can vary dramatically between targets owing to the differences between genomic loci and the availability of enough Cas9/sgRNA (single guide RNA) complex molecules for cleavage. Most methods have so far relied on Cas9 protein engineering or base modifications in the sgRNA sequence to improve CRISPR/Cas9 activity. Here we demonstrate that a structure based rational design of sgRNAs can enhance the efficiency of Cas9 cleavage in vivo. By appending a naturally forming RNA G-quadruplex motif to the 3' end of sgRNAs we can improve its stability and target cleavage efficiency in zebrafish embryos without inducing off-target activity, thereby underscoring its value in the design of better and optimized genome editing triggers. PMID- 29450417 TI - Enhanced magnetic and thermoelectric properties in epitaxial polycrystalline SrRuO3 thin films. AB - Transition metal oxide thin films show versatile electric, magnetic, and thermal properties which can be tailored by deliberately introducing macroscopic grain boundaries via polycrystalline solids. In this study, we focus on the modification of magnetic and thermal transport properties by fabricating single- and polycrystalline epitaxial SrRuO3 thin films using pulsed laser epitaxy. Using the epitaxial stabilization technique with an atomically flat polycrystalline SrTiO3 substrate, an epitaxial polycrystalline SrRuO3 thin film with the crystalline quality of each grain comparable to that of its single-crystalline counterpart is realized. In particular, alleviated compressive strain near the grain boundaries due to coalescence is evidenced structurally, which induced the enhancement of ferromagnetic ordering of the polycrystalline epitaxial thin film. The structural variations associated with the grain boundaries further reduce the thermal conductivity without deteriorating the electronic transport, and lead to an enhanced thermoelectric efficiency in the epitaxial polycrystalline thin films, compared with their single-crystalline counterpart.

AB - Here, we report the delivery of a cell-impermeable [Ru(bpy)2dppz]2+ complex across a cell membrane using a cucurbit[7]uril molecular container. Encapsulation of complex 1 in the cucurbit[7]uril cavity showed an 830-fold enhancement in the luminescence intensity of the non-emissive complex in aqueous solution. This molecular light-switch effect stems from the incorporation of the dppz ligand of 1 inside the CB7 cavity and can be attributed to long range coulombic forces between Ru2+ and the carbonyl portal of CB7 via CHO interactions. This is reflected in the 1H-NMR experiments, and further corroborated by theoretical calculations. PMID- 29450419 TI - Small size yet big action: a simple sulfate anion templated a discrete 78 nuclearity silver sulfur nanocluster with a multishell structure. AB - A discrete 78-nucleus silver-sulfur nanocluster with a sulfate-centered multishell structure was isolated and characterized. Its crystal structure revealed 18 and 60 Ag atoms in the inner and outer shell, respectively. The inner shell of 18-nuclearity Ag atoms is a very rare convex polyhedron featuring an elongated triangular orthobicupola. The incorporation of a sulfate anion and multishell arrangement in the nanocluster led to a dramatic decrease in the band gap (Eg = 1.40 eV). Our study showed that simple anions can also induce the formation of high-nuclearity silver clusters with excellent optical properties.

AB - Organic-inorganic halide perovskites have attracted enormous attention owing to their promising application in photovoltaic devices. The morphology of the perovskites is the key to driving the performance of perovskite devices, which necessitates a systematic study. In this work, two typical morphologies, i.e., flake and cube, of perovskite films are fabricated, and the temperature-dependent optical absorption and photoluminescence properties of the two types of perovskite film are systematically investigated. From the temperature-dependent spectra, both exciton and phase transition temperatures of the flake film are found to be about 10 K lower than those of the cube one. Meanwhile, the influences of the morphology on the exciton binding energy, optical phonon energy and polaron binding energy are quantitatively characterized. The exciton binding of the flake film is nearly three times smaller than that of the cube one, while the phonon coupling energy and the polaron binding energy of the former are about 5 meV and 2 meV larger than those of the latter. Furthermore, the results of photoluminescence lifetime and charge separation efficiency further reveal that the charge carrier kinetics in the two kinds of perovskite films is significantly different. The current study provides a theoretical framework to understand the fundamental physics of perovskites and to promote the design and enhancement of active materials for improved optoelectronic devices.

AB - We report an in situ analysis of nano-micro sodium deposition in an ester-based electrolyte using atomic force microscopy. It is found that sodium dendrites are effectively suppressed by adding fluoroethylene carbonate (FEC) as an electrolyte additive. The decomposition of FEC provides a NaF-containing solid electrolyte interphase with homogenous morphology and high modulus, leading to stable sodium deposition and high Coulombic efficiency (88% over 50 cycles) of the sodium metal anode. PMID- 29450422 TI - Remarkable structural effects on the complexation of actinides with H phosphonates: a combined experimental and quantum chemical study. AB - The structural effects of the carbon chain on the extraction of actinides by organo-phosphorus extractants have been examined experimentally and by computation. Branched butyl H-phosphonates and their linear chain isomer, n-butyl H-phosphonate (DBHP), were synthesised and characterised using IR, NMR and GC-MS techniques. Their physical properties viz. viscosity, density and aqueous solubility have been examined. DBHP, Di-iso-butyl H phosphonate (DiBHP) and Di sec-butyl H phosphonate (DsBHP) were employed for the extraction of uranium and americium ions from nitric acid. 233U (alpha-tracer) and 241Am (gamma-tracer) were employed as representative isotopes for the extraction of U and Am, respectively, and their distribution ratios (D) were obtained as a function of nitric acid concentration (0.01-8 M). Branching of the alkyl chain at the secondary carbon atom showed unexpected neutral extractant behaviour for DsBHP which is generally classified as an acidic extractant. The acid-dependent dual extraction mechanisms for the H-phosphonates have been examined both experimentally and through quantum chemical calculations. This dramatic effect can be partly attributed to the hindrance in the formation of the enol tautomer through the strengthening of the P[double bond, length as m-dash]OH hydrogen bonding in the DsBHP extractant. Density functional theory (DFT) based calculations were carried out to understand the complexation behaviour of actinides with the two extractants. Possible structures and binding affinities of actinides with H-phosphonates have been deduced from electronic structure calculations. Finally, the trends in distribution ratios were additionally explored and correlated with experimental observations for both metal ions.

AB - An important reaction step in the industrial production of NaClO3 (electrochemical chlorate process) is the thermal decomposition of HOCl/OCl- to yield ClO3- and Cl-. It is widely accepted that this reaction is accelerated by aqueous chromium(vi) species. A detailed kinetic study was conducted under industrially relevant conditions, i.e. at high ionic strength (6.0 M) and elevated temperature (80 degrees C), to investigate this phenomenon. The decomposition of hypochlorous acid was followed in the presence of Cr(vi) or phosphate (PO43-) or without any additive. In addition to the beneficial pH buffering effect of Cr(vi), the CrO42- form of chromium(vi) was found to slightly catalyze the decomposition of hypochlorous acid. The overall rate of HOCl decomposition can be expressed as -dcHOCl/dt = kdec[HOCl]2[OCl-] + kcat[HOCl]2[CrO42-]. The corresponding rate constants were determined, kdec = 9.4 +/- 0.1 M-2 s-1 and kcat = 4.6 +/- 0.8 M-2 s-1, and mechanistic interpretation of the catalytic rate law is given. The contribution of the catalytic path to the overall rate of decomposition changes from ca. 30% at pH = 8 to ca. 70% at pH = 6.

AB - CD44, an abundantly expressed adhesion molecule, and its alternative splice variants have been associated with tumorigenesis and metastasis. In the context of gastric cancer (GC), de novo expression of CD44 variant 6 (CD44v6) is found in more than 60% of GCs, but its role in the pathogenesis and progression of this type of cancer remains unclear. Using a combination of media conditioning experiments and decellularized extracellular matrices (ECMs), this study investigates the hypothesis that CD44v6 overexpression enhances tumor cell malignant behavior by modulating stromal cell-mediated ECM remodeling. Our findings indicate that soluble factors secreted by CD44v6 expressing GC cells particularly increase proliferation and myofibroblastic differentiation of adipose stromal cells (ASCs). These changes in ASC phenotype mediate the deposition of fibrotic/desmoplastic ECM that, in turn, stimulates GC proliferation and inhibits GC clustering. Pharmacological inhibition of matrix metalloproteinase (MMP) activity in tumor cells abrogated matrix-induced changes in tumor cell malignant behavior. Additionally, studies in mice confirmed the pathological relevance of CD44v6 expression and consequential changes in ECM remodeling to gastric tumorigenesis in vivo. Collectively, these results indicate a direct link between CD44v6, ECM remodeling, and GC malignant behavior opening new insights into potential CD44v6-targeted therapies.

AB - Carbon nanotube thin film transistors (CNT-TFTs) are regarded as promising technology for active matrix pixel driving circuits of future flat panel displays (FPD). For FPD application, unipolar thin film transistors (TFTs) with high mobility (MU), high on-state current (ION), low off-current (IOFF) at high source/drain bias and small hysteresis are required simultaneously. Though excellent values of those performance metrics have been realized individually in different reports, the overall performance of previously reported CNT-TFTs has not met the above requirements. In this paper, we found that yttrium oxide (Y2O3) capping is helpful in improving both ION and MU of CNT-TFTs. Combining Y2O3 capping and Al2O3 passivation, unipolar CNT-TFTs with high ION/IOFF (>107) and low IOFF (~pA) at -10.1 V source/drain bias, and relatively small hysteresis in the range of -30 V to +30 V gate voltage were achieved, which are capable of active matrix display driving. PMID- 29450428 TI - Dynamics of bridge-loop transformation in a membrane with mixed monolayer/bilayer structures. AB - Instead of forming a typical bilayer or monolayer membrane, both the bridge (I shape) and loop (U-shape) conformations coexist in the planar membranes formed by ABA triblock copolymers in a selective solvent. The non-equilibrium and equilibrium relaxation dynamics of polymer conformations are monitored. The non equilibrium relaxation time depends on the initial composition and increases with an increase in the immiscibility between A and B blocks. The equilibrium composition of the loop-shape polymer is independent of the initial composition and A-B immiscibility. However, the extent of equilibrium composition fluctuations subsides as the A and B blocks become highly incompatible. The influences of the A-B immiscibility on the geometrical, mechanical, and transport properties of the membrane have also been investigated. As the immiscibility increases, the overall membrane thickness and the B block layer thickness (h) increase because of the increment in the molecular packing density. As a result, both the stretching (KA) and bending (KB) moduli grow significantly with the increasing A-B immiscibility. Consistent with the case of typical membranes, the ratio KB/KAh2 = 2 * 10-3 is a constant. Although the lateral diffusivity of polymers is insensitive to immiscibility, the membrane permeability decreases substantially as the A-B immiscibility is increased.

AB - An addition/cyclization reaction of 1,6-diynes was developed for the synthesis of highly substituted 1,2-dialkylidenecycloalkanes. In this work, 1,6-diynes reacted with (dimethylphenylsilyl)pinacol-borane in the presence of a palladium catalyst to afford 1,2-dialkylidenecycloalkanes bearing silyl and boryl groups with a (Z,Z)-configuration in good to excellent yields. Moreover, the corresponding products could be easily converted into other synthetically useful compounds. This protocol provides an efficient and practical method of heteroelement-element linkage addition to the unsaturated 1,6-diynes.

AB - One of the greatest challenges in the enhancement of the electrical properties of conductive mayenite [Ca24Al28O64]4+(4e-) (hereinafter C12A7:e-) is the design of a more suitable/simple synthesis strategy that can be employed to obtain the required properties such as excellent stable electrical conductivity, a high electron concentration, outstanding mobility, and an exceptionally large surface area. Therefore, to synthesize C12A7:e- in the metallic state, we proposed a facile, direct synthesis strategy based on an optimized sol-gel combustion method under a nitrogen gas environment using the low-cost precursors Ca(NO3)2.4H2O and Al(NO3)3.9H2O. Using this developed strategy, we successfully synthesized moderately conductive nanoscale C12A7:e- powder, but with unexpected carbon components (reduced graphene oxide (rGO) and/or graphene oxide (GO)). The synthesized C12A7:e- composite at room temperature has an electrical conductivity of about 21 S cm-1, a high electron concentration of approximately 1.5 * 1021 cm 3, and a maximum specific surface area of 265 m2 g-1. Probably, the synthesized rGO was coated on nanocage C12A7:e- particles. In general, the C12A7:e- electride is sensitive to the environment (especially to oxygen and moisture) and protected by an rGO coating on C12A7:e- particles, which also enhances the mobility and keeps the conductivity of C12A7:e- electride stable over a long period. Doped mayenite electride exhibits a conductivity that is strongly dependent on the substitution level. The conductivity of gallium-doped mayenite electride increases with the doping level and has a maximum value of 270 S cm-1, which for the first time has been reported for the stable C12A7:e- electride. In the case of Si-substituted calcium aluminate, the conductivity has a maximum value of 222 S cm-1 at room temperature.

AB - Our current knowledge of cloud condensation nuclei (CCN) activity and the hygroscopicity of secondary organic aerosol (SOA) depends on the particle size and composition, explicitly, the thermodynamic properties of the aerosol solute and subsequent interactions with water. Here, we examine the CCN activation of 3 SOA systems (2 biogenic single precursor and 1 mixed precursor SOA system) in relation to gas-phase decay. Specifically, the relationship between time, gas phase precursor decay and CCN activity of 100 nm SOA is studied. The studied SOA systems exhibit a time-dependent growth of CCN activity at an instrument supersaturation of ~0.2%. As such, we define a critical activation time, t50, above which a 100 nm SOA particle will activate. The critical activation time for isoprene, longifolene and a mixture of the two precursor SOA is 2.01 hours, 2.53 hours and 3.17 hours, respectively. The activation times are then predicted with gas-phase kinetic data inferred from measurements of precursor decay. The gas phase prediction of t50 agrees well with CCN measured t50 (within 0.05 hours of the actual critical times) and suggests that the gas-to-particle phase partitioning may be more significant for SOA CCN prediction than previously thought.

AB - The atmosphere is the major contributor of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in the Baltic Sea environment. In this study, we investigated the potential of using metals along with PCDD/Fs as markers of important emission sources of PCDD/Fs in air. The air concentrations of PCDD/F congeners (n = 17), other persistent organic pollutants (n = 8) and metals (n = 16) were determined in summer and winter air using high volume samplers at a rural field station (Aspvreten, Sweden) located close to the Baltic Sea coast. During winter, PCDD/F levels were on average 20 times higher than in summer (5.1 +/- 5.8 fg toxicity equivalents (TEQ) m-3 and 0.26 +/- 0.18 fg TEQ m-3, respectively) mostly due to a higher fraction of PCDFs. The increased levels of PCDD/Fs were pronounced mainly in air masses that had travelled from southern (S) and eastern (E) compass sectors. A principal component analysis (PCA) of metal levels in Scots pine (Pinus sylvestris) needles sampled to reflect various air emission source types helped to identify potential marker metals for selected known atmospheric emission sources of PCDD/Fs and to rank among the candidate source types. Brown coal burning, domestic burning and heavy oil burning appeared to be the source types that contribute most of the PCDD/Fs in Baltic Sea air. The current study demonstrates a successful approach for source tracing of PCDD/Fs in air, where integrated indices from seasonal and spatial patterns of PCDD/Fs as well as metal source markers were used to trace and rank sources.

AB - Solid-to solid-state reversible phase transitions are widely used in switchable dielectrics, ferroelectrics, piezoelectrics, and pyroelectric and non-linear optical materials. Herein we report a new crown ether clathrate, [Habf-(18-crown 6)1.5]+ [PF6]- (Habf = p-ammonium benzene formamide) which shows an interesting reversible phase transition near room temperature (263 K). X-ray single crystal diffraction analysis shows that the synergetic rotation motion between the 18 crown-6 crown ethers and the order-disorder motions of both hexafluorophosphate guest anions and 18-crown-6 crown ether host molecules lead to the phase transition. This reversible phase transition is confirmed by an evident thermal anomaly behavior around 263 K. The apparent step-like dielectric change around the phase transition indicates that it has potential application in dielectric switches.

AB - Black phosphorene (BP) has shown anisotropic, electronic, mechanical, and thermal properties for various promising applications in recent years. To take full advantage of this unique anisotropy in its further functional design and application, it is of paramount importance to separate BP with well-defined chirality quickly and precisely. In this paper, we propose three efficient methods to separate BP ribbons with different chiralities by utilizing their strong chirality-dependent bending stiffness. Our results show that the bending stiffness in the zigzag direction is 4 times larger than that in the armchair direction. The mechanical anisotropy and bending-binding competition are used to realize chirality-dependent design. To fold, wrap or scroll the BP nanoribbons, it is necessary to overcome the bending stiffness by applying the binding energy between the BP nanoribbons and the contact surfaces. Due to the mechanical anisotropy, the BP nanoribbons could easily be folded, wrapped and scrolled along the armchair direction rather than the zigzag direction. Therefore, we introduce this characteristic in our chirality separation designs as, the self-folding model to fold up the armchair BP nanoribbons by nanoparticles, the suspension bridge sieve model to pull down the armchair BP nanoribbons, and the nanorod roller model to scroll up the armchair nanoribbons. Our separation methods in this research can be extended to other 2D materials with anisotropic mechanical properties. We hope our findings would offer a novel route for the manufacturing of BP-based electronic devices and self-assembly of nano-devices.

AB - Li1.6Mn1.6O4 is a representative ion sieve material that is used to recover lithium from salt brines and bitterns owing to its high lithium ion adsorption capacity reaching 11.9-44 mg g-1. However, manganese dissolution during acid treatment hinders the industrial application of the material. For investigating the mechanism of manganese dissolution, the precursor Li1.6Mn1.6O4 and ion sieve H1.6Mn1.6O4 were prepared and characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FT IR), chemical content analyses, diffuse reflectance infrared Fourier-transform spectroscopy (DRIFTS), and X-ray photoelectron spectroscopy (XPS). The results of XRD, SEM, and FT-IR showed that the bulk phase of Li1.6Mn1.6O4 retained the spinel structure, whereas the lattice diminished during acid treatment. The results of chemical content analyses showed that the bulk phase of Li1.6Mn1.6O4 contained a few trivalent manganese atoms and that the mean valence of manganese in the material increased during acid treatment. DRIFTS and XPS exhibited that the surface of Li1.6Mn1.6O4 was mostly full of tetravalent manganese and retained the spinel structure during acid treatment. In the proposed mechanism of manganese dissolution, an electron of trivalent manganese in the bulk phase transfers to the surface and is captured by tetravalent manganese within the acidic environment. Then, tetravalent manganese is converted to bivalent manganese after acquiring sufficient electrons, and dissolution occurs simultaneously.

AB - The first Csp3-Csp2 cross-coupling using aldehydes as latent alpha-alkoxyalkyl anion equivalents has been achieved. The synergistic palladium/copper-catalyzed reaction of aromatic aldehydes and aryl bromides with a silylboronate afforded the three-component coupling products, silyl-protected benzhydrol derivatives. The reaction pathway involves the catalytic formation of a nucleophilic alpha silyloxybenzylcopper(i) species followed by its palladium-catalyzed cross coupling with aryl bromides.

AB - Importance: Mental health can have an impact on patient satisfaction with rhinoplasty. However, the association between mental health and patient satisfaction with functional outcomes of rhinoplasty is poorly understood. Objective: To determine whether preoperative mental health is associated with satisfaction with functional outcomes of rhinoplasty. Design, Setting, and Participants: This case-control study assessed baseline nasal function and postsurgical functional outcomes for 88 consecutive patients undergoing rhinoplasty with both cosmetic and functional goals at 2 tertiary rhinologic centers in Sydney, Australia. Exposures: Poor mental well-being was defined preoperatively by the Optum SF-36v2 Health Survey mental component summary. Main Outcomes and Measures: Nasal function was assessed with patient-reported outcome measures, including visual analog scales, the Nasal Obstruction Symptom Evaluation Scale (NOSE), the 22-item Sinonasal Outcome Test (SNOT-22), and Likert scales. Objective outcomes included nasal peak inspiratory flow, nasal airway resistance, and minimum cross-sectional area. All outcomes were assessed preoperatively and 6 months postoperatively. The 36-item Optum SF-36v2 Health Survey mental component summary was used to assess mental well-being, with a score of less than 40 indicating poor mental well-being and a score 40 or higher indicating normal well-being. Results: Mean (SD) patient age was 37.6 (12.9) years and 53 of 88 (60.2%) were women. The mental component summary defined impaired well-being in n = 24 (cases) and normal well-being in n = 64 (controls). There were improvements in the total study population across most nasal function outcomes and in both groups. After rhinoplasty, benefit was seen for both groups in visual analog scale (left side mean [SD] change, 18 [30]; P < .001 and right side mean [SD] change, 24 [30]; P < .001); NOSE (mean [SD] change, 1.35 [1.21]; P < .001); and SNOT-22 (mean [SD] change, 0.81 [0.88]; P < .001) scores. Nasal peak inspiratory flow improved for both groups (mean [SD] change, 32 [45] L/min; P < .001), while nasal airway resistance and minimum cross-sectional area remained similar (change in nasal airway resistance, 0.086 Pa/cm3/s; 95% CI, -0.007 Pa/cm3/s to 0.179 Pa/cm3/s and change in minimum cross-sectional area, -0.04 cm2; 95% CI, -0.21 cm2 to 0.13 cm2). Patients with poor mental health had similar improvements in nasal function compared with controls. Conclusions and Relevance: Rhinoplasty imparts similar benefits to nasal function assessed by patient reported outcome measures and objective airflow measures regardless of preoperative mental health status.

AB - Importance: Enhanced understanding of factors associated with symptomatic and functional recovery is instrumental to designing personalized treatment plans for people with schizophrenia. To date, this is the first study using network analysis to investigate the associations among cognitive, psychopathologic, and psychosocial variables in a large sample of community-dwelling individuals with schizophrenia. Objective: To assess the interplay among psychopathologic variables, cognitive dysfunctions, functional capacity, personal resources, perceived stigma, and real-life functioning in individuals with schizophrenia, using a data-driven approach. Design, Setting, and Participants: This multicenter, cross-sectional study involved 26 university psychiatric clinics and/or mental health departments. A total of 921 community-dwelling individuals with a DSM-IV diagnosis of schizophrenia who were stabilized on antipsychotic treatment were recruited from those consecutively presenting to the outpatient units of the sites between March 1, 2012, and September 30, 2013. Statistical analysis was conducted between July 1 and September 30, 2017. Main Outcomes and Measures: Measures covered psychopathologic variables, neurocognition, social cognition, functional capacity, real-life functioning, resilience, perceived stigma, incentives, and service engagement. Results: Of 740 patients (221 women and 519 men; mean [SD] age, 40.0 [10.9] years) with complete data on the 27 study measures, 163 (22.0%) were remitted (with a score of mild or better on 8 core symptoms). The network analysis showed that functional capacity and everyday life skills were the most central and highly interconnected nodes in the network. Psychopathologic variables split in 2 domains, with positive symptoms being one of the most peripheral and least connected nodes. Functional capacity bridged cognition with everyday life skills; the everyday life skills node was connected to disorganization and expressive deficits. Interpersonal relationships and work skills were connected to avolition; the interpersonal relationships node was also linked to social competence, and the work skills node was linked to social incentives and engagement with mental health services. A case-dropping bootstrap procedure showed centrality indices correlations of 0.75 or greater between the original and randomly defined samples up to 481 of 740 case-dropping (65.0%). No difference in the network structure was found between men and women. Conclusions and Relevance: The high centrality of functional capacity and everyday life skills in the network suggests that improving the ability to perform tasks relevant to everyday life is critical for any therapeutic intervention in schizophrenia. The pattern of network node connections supports the implementation of personalized interventions.

PMID- 29450452 TI - Effect of Neoadjuvant Chemotherapy Plus Regional Hyperthermia on Long-term Outcomes Among Patients With Localized High-Risk Soft Tissue Sarcoma: The EORTC 62961-ESHO 95 Randomized Clinical Trial. AB - Importance: Patients with soft tissue sarcoma are at risk for local recurrence and distant metastases despite optimal local treatment. Preoperative anthracycline plus ifosfamide chemotherapy improves outcome in common histological subtypes. Objective: To analyze whether the previously reported improvement in local progression-free survival by adding regional hyperthermia to neoadjuvant chemotherapy translates into improved survival. Design, Setting, and Participants: Open-label, phase 3 randomized clinical trial to evaluate the efficacy and toxic effects of neoadjuvant chemotherapy plus regional hyperthermia. Adult patients (age >=18 years) with localized soft tissue sarcoma (tumor >=5 cm, French Federation Nationale des Centers de Lutte Contre le Cancer [FNCLCC] grade 2 or 3, deep) were accrued across 9 centers (6, Germany; 1, Norway; 1, Austria; 1, United States) from July 1997 to November 2006. Follow-up ended December 2014. Interventions: After stratification for tumor presentation and site, patients were randomly assigned to either neoadjuvant chemotherapy consisting of doxorubicin, ifosfamide, and etoposide alone, or combined with regional hyperthermia. Main Outcomes and Measures: The primary end point was local progression-free survival. Secondary end points included treatment safety and survival, with survival defined from date of randomization to death due to disease or treatment. Patients lost to follow-up were censored at the date of their last follow-up. Results: A total of 341 patients were randomized, and 329 (median [range] age, 51 [18-70] years; 147 women, 182 men) were eligible for the intention-to-treat analysis. By December 2014, 220 patients (67%; 95% CI, 62% 72%) had experienced disease relapse, and 188 (57%; 95% CI, 52%-62%) had died. Median follow-up was 11.3 years. Compared with neoadjuvant chemotherapy alone, adding regional hyperthermia improved local progression-free survival (hazard ratio [HR], 0.65; 95% CI, 0.49-0.86; P = .002). Patients randomized to chemotherapy plus hyperthermia had prolonged survival rates compared with those randomized to neoadjuvant chemotherapy alone (HR, 0.73; 95% CI, 0.54-0.98; P = .04) with 5-year survival of 62.7% (95% CI, 55.2%-70.1%) vs 51.3% (95% CI, 43.7% 59.0%), respectively, and 10-year survival of 52.6% (95% CI, 44.7%-60.6%) vs 42.7% (95% CI, 35.0%-50.4%). Conclusions and Relevance: Among patients with localized high-risk soft tissue sarcoma the addition of regional hyperthermia to neoadjuvant chemotherapy resulted in increased survival, as well as local progression-free survival. For patients who are candidates for neoadjuvant treatment, adding regional hyperthermia may be warranted. Trial Registration: clinicaltrials.gov Identifier: NCT00003052. PMID- 29450453 TI - The Association of Age With Clinical Presentation and Comorbidities of Pyoderma Gangrenosum. AB - Importance: Pyoderma gangrenosum is an inflammatory neutrophilic dermatosis. Current knowledge of this rare disease is limited owing to a lack of validated diagnostic criteria and large population studies. Objective: To evaluate the association of age with the clinical presentation and comorbidities of pyoderma gangrenosum. Design, Setting, and Participants: This was a multicenter retrospective cohort study performed at tertiary academic referral centers in urban settings. Adults (>=18 years) who were evaluated and diagnosed as having pyoderma gangrenosum at the Brigham and Women's and Massachusetts General Hospitals from 2000 to 2015 and the University of Pennsylvania Health System from 2006 to 2016 were included. Main Outcomes and Measures: Patient demographics, clinical features, medical comorbidities, and treatment. Results: Of the 356 validated cases of pyoderma gangrenosum included in the study, 267 (75%) were women and 284 (84.8%) were white. The mean (SD) age at presentation was 51.6 (17.7) years. Pathergy was recorded in 100 patients (28.1%). A total of 238 patients (66.9%) had associated medical comorbidities: inflammatory bowel disease in 146 patients (41.0%); inflammatory arthritis in 73 patients (20.5%); solid organ malignant neoplasms in 23 patients (6.5%); hematologic malignant neoplasms in 21 patients (5.9%); and hematologic disorders, specifically monoclonal gammopathy of undetermined significance, myelodysplastic syndrome, and polycythemia vera in 17 patients (4.8%). When stratified by age, pathergy was more common in patients 65 years or older (36.3% vs 24.3%; P = .02). Inflammatory bowel disease was the only medical comorbidity that was more common in patients younger than 65 years (47.7% vs 26.6%; P < .001), while a number of medical comorbidities were more common in those 65 years or older, including rheumatoid arthritis (13.3% vs 6.2%; P = .03), ankylosing spondylitis (1.8% vs 0%; P = .04), solid organ malignant neoplasms (13.3% vs 3.3%; P < .001), hematologic malignant neoplasms (9.7% vs 4.1%; P = .04), and the aforementioned hematologic disorders (10.6% vs 2.1%; P < .001). Conclusions and Relevance: Although clinical presentation in this large cohort was similar between different age groups, disease associations varied by age. The findings of this study may allow for a more focused, age-specific evaluation of patients with pyoderma gangrenosum. PMID- 29450455 TI - Oregon's Death With Dignity Act-Reply.

AB - Importance: No US national data are available on the prevalence and correlates of DSM-5-defined major depressive disorder (MDD) or on MDD specifiers as defined in DSM-5. Objective: To present current nationally representative findings on the prevalence, correlates, psychiatric comorbidity, functioning, and treatment of DSM-5 MDD and initial information on the prevalence, severity, and treatment of DSM-5 MDD severity, anxious/distressed specifier, and mixed-features specifier, as well as cases that would have been characterized as bereavement in DSM-IV. Design, Setting, and Participants: In-person interviews with a representative sample of US noninstitutionalized civilian adults (>=18 years) (n = 36 309) who participated in the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions III (NESARC-III). Data were collected from April 2012 to June 2013 and were analyzed in 2016-2017. Main Outcomes and Measures: Prevalence of DSM-5 MDD and the DSM-5 specifiers. Odds ratios (ORs), adjusted ORs (aORs), and 95% CIs indicated associations with demographic characteristics and other psychiatric disorders. Results: Of the 36 309 adult participants in NESARC-III, 12-month and lifetime prevalences of MDD were 10.4% and 20.6%, respectively. Odds of 12-month MDD were significantly lower in men (OR, 0.5; 95% CI, 0.46-0.55) and in African American (OR, 0.6; 95% CI, 0.54-0.68), Asian/Pacific Islander (OR, 0.6; 95% CI, 0.45-0.67), and Hispanic (OR, 0.7; 95% CI, 0.62-0.78) adults than in white adults and were higher in younger adults (age range, 18-29 years; OR, 3.0; 95% CI, 2.48-3.55) and those with low incomes ($19 999 or less; OR, 1.7; 95% CI, 1.49-2.04). Associations of MDD with psychiatric disorders ranged from an aOR of 2.1 (95% CI, 1.84-2.35) for specific phobia to an aOR of 5.7 (95% CI, 4.98-6.50) for generalized anxiety disorder. Associations of MDD with substance use disorders ranged from an aOR of 1.8 (95% CI, 1.63-2.01) for alcohol to an aOR of 3.0 (95% CI, 2.57-3.55) for any drug. Most lifetime MDD cases were moderate (39.7%) or severe (49.5%). Almost 70% with lifetime MDD had some type of treatment. Functioning among those with severe MDD was approximately 1 SD below the national mean. Among 12.9% of those with lifetime MDD, all episodes occurred just after the death of someone close and lasted less than 2 months. The anxious/distressed specifier characterized 74.6% of MDD cases, and the mixed features specifier characterized 15.5%. Controlling for severity, both specifiers were associated with early onset, poor course and functioning, and suicidality. Conclusions and Relevance: Among US adults, DSM-5 MDD is highly prevalent, comorbid, and disabling. While most cases received some treatment, a substantial minority did not. Much remains to be learned about the DSM-5 MDD specifiers in the general population. PMID- 29450465 TI - Pediatric-Inspired Treatment Regimens for Adolescents and Young Adults With Philadelphia Chromosome-Negative Acute Lymphoblastic Leukemia: A Review. AB - Importance: The incidence of acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL) in adolescent and young adult (AYA) patients (age range, 15-39 years) in the United States is increasing at a greater rate than in younger or older persons. Their optimal treatment has been increasingly debated as pediatric regimens have become more widely used in the age group. This review compares the basic features of pediatric and adult chemotherapy regimens for ALL and LBL, recognizes and describes the challenges of the pediatric regimen, and suggests strategies to facilitate its adoption for AYAs with ALL and LBL. Observations: All but 2 of 25 published comparisons of outcomes with pediatric and adult regimens for ALL and LBL in AYAs and 1 meta-analysis favor the pediatric regimen. After more than a half-century of clinical trials of the pediatric regimens, including at least 160 phase 3 trials in the United States, the pediatric regimens have become far more complex than most adult regimens. Asparaginase, a critical component of the pediatric regimens, is more difficult to administer to AYAs (and older patients) but nonetheless has a favorable benefit to toxicity ratio for AYAs. A dramatic reduction in outcome of ALL and LBL during the AYA years (the "survival cliff") is coincident with similar reductions in proportions of AYAs referred to academic centers and enrolled on clinical trials (the "accrual cliff" and "referral cliff"). Conclusions and Relevance: The accumulating data increasingly support treating AYAs with ALL and LBL with a pediatric-inspired regimen or an approved institutional or national clinical trial tailored for this patient group. A need to develop clinical trials specifically for AYAs and to encourage their participation is paramount, with a goal to improve both the quantity and quality of survival.

PMID- 29450466 TI - Diagnostic Criteria of Ulcerative Pyoderma Gangrenosum: A Delphi Consensus of International Experts. AB - Importance: Pyoderma gangrenosum is a rare inflammatory skin condition that is difficult to diagnose. Currently, it is a "diagnosis of exclusion," a definition not compatible with clinical decision making or inclusion for clinical trials. Objective: To propose and validate diagnostic criteria for ulcerative pyoderma gangrenosum. Evidence Review: Diagnostic criteria were created following a Delphi consensus exercise using the RAND/UCLA Appropriateness Method. The criteria were validated against peer-reviewed established cases of pyoderma gangrenosum and mimickers using k-fold cross-validation with methods of multiple imputation. Findings: Delphi exercise yielded 1 major criterion-biopsy of ulcer edge demonstrating neutrophilic infiltrate-and 8 minor criteria: (1) exclusion of infection; (2) pathergy; (3) history of inflammatory bowel disease or inflammatory arthritis; (4) history of papule, pustule, or vesicle ulcerating within 4 days of appearing; (5) peripheral erythema, undermining border, and tenderness at ulceration site; (6) multiple ulcerations, at least 1 on an anterior lower leg; (7) cribriform or "wrinkled paper" scar(s) at healed ulcer sites; and (8) decreased ulcer size within 1 month of initiating immunosuppressive medication(s). Receiver operating characteristic analysis revealed that 4 of 8 minor criteria maximized discrimination, yielding sensitivity and specificity of 86% and 90%, respectively. Conclusions and Relevance: This Delphi exercise produced 1 major criterion and 8 minor criteria for the diagnosis of ulcerative pyoderma gangrenosum. The criteria may serve as a guideline for clinicians, allowing for fewer misdiagnoses and improved patient selection for clinical trials.

AB - Importance: The combination of a triple-drug chemotherapy regimen with an anti epidermal growth factor receptor (EGFR) agent as a first-line treatment of metastatic colorectal cancer (mCRC) showed promising activity along with safety concerns in single-arm phase 2 trials. The role of maintenance following chemotherapy and anti-EGFR and the optimal regimen to be adopted are not established.

Design, Setting, and Participants: In a prospective, noncomparative, open-label, multicenter, randomized phase 2 trial, patients aged 18 to 75 years with unresectable, previously untreated RAS and BRAF wild-type (before amendment, KRAS wild-type) mCRC were recruited from 21 oncology units in Italy from October 19, 2011, to March 1, 2015 (followed up through May 31, 2017). In total, 323 patients were screened and 143 were randomized to 2 treatment arms to receive as a first-line induction a regimen of mFOLFOXIRI plus cetuximab followed by cetuximab (arm A) or bevacizumab (arm B) until disease progression. Primary analyses were conducted in a modified intention-to-treat population. Interventions: mFOLFOXIRI plus cetuximab repeated every 2 weeks for up to 8 cycles, followed by maintenance with cetuximab or bevacizumab until disease progression. Main Outcomes and Measures: The primary end point was the 10-month progression-free rate (PFR); secondary end points included progression-free and overall survival, response rate, rate of metastases resection, and adverse events. Results: Of 143 patients randomized, 116 (81.1%) (median [interquartile range (IQR)] age, 59.5 [53-67] years; 34 [29.3%] women) had RAS and BRAF wild-type mCRC. At a median (IQR) follow-up of 44.0 (30.5-52.1) months, 10-month PFRs were 50.8% (90% CI, 39.5%-62.2%) in arm A and 40.4% (90% CI, 29.4%-52.1%) in arm B. The overall response rate was 71.6% (95% CI, 62.4%-79.5%). Main grade 3/4 adverse events were neutropenia (occurring in 36 patients [31%]), diarrhea (in 21 patients [18%]), skin toxic effects (in 18 patients [16%]), asthenia (in 11 patients [9%]), stomatitis (in 7 patients [6%]), and febrile neutropenia (in 3 patients [3%]). Conclusions and Relevance: Although neither of the 2 arms met the primary end point, the findings indicate that a 4 month induction regimen of mFOLFOXIRI plus cetuximab is feasible and provides relevant activity results, leading to a high surgical resection rate.

PMID- 29450469 TI - Association Between Bariatric Surgery and Rates of Continuation, Discontinuation, or Initiation of Antidiabetes Treatment 6 Years Later. AB - Importance: Few large-scale long-term prospective cohort studies have assessed changes in antidiabetes treatment after bariatric surgery. Objective: To describe the association between bariatric surgery and rates of continuation, discontinuation, or initiation of antidiabetes treatment 6 years after bariatric surgery compared with a matched control obese group. Design, Setting, and Participants: This nationwide observational population-based cohort study extracted health care reimbursement data from the French national health insurance database from January 1, 2008, to December 31, 2015. All patients undergoing primary bariatric surgery in France between January 1 and December 31, 2009, were matched on age, sex, body mass index category, and antidiabetes treatment with control patients hospitalized for obesity in 2009 with no bariatric surgery between 2005 and 2015. Exposures: Bariatric surgery, including adjustable gastric banding (AGB), gastric bypass (GBP), and sleeve gastrectomy (SG). Main Outcome and Measure: Reimbursement for antidiabetes drugs. Mixed effects logistic regression models estimated factors of discontinuation or initiation of antidiabetes treatment over a period of 6 years. Results: In 2009, a total of 15 650 patients (mean [SD] age, 38.9 [11.2] years; 84.6% female; 1633 receiving antidiabetes treatment) underwent primary bariatric surgery, with 48.5% undergoing AGB, 27.7% undergoing GBP, and 22.0% undergoing SG. Among patients receiving antidiabetes treatment at baseline, the antidiabetes treatment discontinuation rate was higher 6 years after bariatric surgery than in controls (-49.9% vs -9.0%, P < .001). In multivariable analysis, the main predictive factors for discontinuation were the following: GBP (odds ratio [OR], 16.7; 95% CI, 13.0-21.4), SG (OR, 7.30; 95% CI, 5.50-9.50), and AGB (OR, 4.30; 95% CI, 3.30 5.60) compared with no bariatric surgery, as well as insulin use (OR, 0.17; 95% CI, 0.13-0.22), dual therapy without insulin (OR, 0.38; 95% CI, 0.32-0.45) vs monotherapy, lipid-lowering treatment (OR, 0.76; 95% CI, 0.63-0.91), antidepressant treatment (OR, 0.67; 95% CI, 0.55-0.81), and age (OR, 0.96; 95% CI, 0.95-0.97) per year. For patients without antidiabetes treatment at baseline, the 6-year antidiabetes treatment initiation rate was much lower after bariatric surgery than in controls (1.4% vs 12.0%, P < .001). In multivariable analysis, protective factors were GBP (OR, 0.06; 95% CI, 0.04-0.09), SG (OR, 0.08; 95% CI, 0.06-0.11), and AGB (OR, 0.16; 95% CI, 0.14-0.20) vs controls, and risk factors were as follows: body mass index category (OR, 2.04; 95% CI, 1.68-2.47 for >=50.0 vs 30.0-39.9 and OR, 1.68; 95% CI, 1.49-1.90 for 40.0-49.9 vs 30.0-39.9), antihypertensive treatment (OR, 1.49; 95% CI, 1.33-1.67), low income (OR, 1.43; 95 % CI, 1.26-1.62), and age (OR, 1.04; 95 % CI, 1.03-1.05) per year. Conclusions and Relevance: Bariatric surgery was associated with a significantly higher 6 year postoperative antidiabetes treatment discontinuation rate compared with baseline and with an obese control group without bariatric surgery. PMID- 29450470 TI - Incidence of Delayed Intracranial Hemorrhage in Older Patients After Blunt Head Trauma. AB - Importance: Current guidelines conflict on the management of older adults who have blunt head trauma taking anticoagulant and antiplatelet medications. This is partially due to the limited data comparing patients who are taking these medications with those who are not. Objective: To investigate the incidence of delayed traumatic intracranial hemorrhage in older adults with head trauma, including those taking anticoagulant and antiplatelet medications. Design, Setting, and Participants: This prospective observational cohort study included patients 55 years and older who had blunt head trauma and were transported via emergency medical services between August 1, 2015, and September 30, 2016. The setting was a multicenter study conducted at 11 hospitals in northern California. Patients were excluded if they had traumatic intracranial hemorrhage on the initial cranial computed tomographic scan, did not have a cranial computed tomographic scan performed at the initial emergency department visit, refused consent for a follow-up telephone call, or did not have reliable means of follow up. Main Outcome and Measure: The primary outcome of this study was the incidence of delayed traumatic intracranial hemorrhage within 14 days of injury. Results: Among 859 patients enrolled in the study, the median age was 75 years (interquartile range, 64-85 years), and 389 (45.3%) were male. A total of 343 patients (39.9%) were taking an anticoagulant or antiplatelet medication. Three patients (0.3%; 95% CI, 0.1%-1.0%) had a delayed traumatic intracranial hemorrhage. Of the 3 patients, 1 of 75 patients (1.3%; 95% CI, 0.0%-7.2%) who were taking warfarin sodium alone and 2 of 516 patients (0.4%; 95% CI, 0.1%-1.4%) who were not taking any anticoagulant or antiplatelet medication had a delayed traumatic intracranial hemorrhage. Thirty-nine patients (4.5%; 95% CI, 3.2%-6.2%) were lost to follow-up. Conclusions and Relevance: Overall, the incidence of delayed intracranial hemorrhage in older adults who have blunt head trauma is low, including patients taking an anticoagulant or antiplatelet medication. These findings suggest that routine observation and serial cranial computed tomography may not be necessary in these patients. PMID- 29450472 TI - Otorhinolaryngology and Diving-Part 1: Otorhinolaryngological Hazards Related to Compressed Gas Scuba Diving: A Review. AB - Importance: Scuba diving is becoming increasingly popular. However, scuba diving is associated with specific risks; 80% of adults and 85% of juvenile divers (aged 6-17 years) have been reputed to have an ear, nose, or throat complaint related to diving at some point during their diving career. Divers frequently seek advice from primary care physicians, diving physicians, and otorhinolaryngologists, not only in the acute setting, but also related to the long-term effects of diving. Observations: The principles underpinning diving-related injuries that may present to the otorhinolaryngologist rely on gas volume and gas saturation laws, and the prevention of these injuries requires both that the diver is skilled and that their anatomy allows for pressure equalization between the various anatomical compartments. The overlapping symptoms of middle ear barotrauma, inner ear barotrauma, and inner ear decompression sickness can cause a diagnostic conundrum, and a thorough history of both the diver's symptoms and the dive itself are required to elucidate the diagnosis. Correct diagnosis and appropriate treatment result in a more timely return to safe diving. Conclusions and Relevance: The aim of this review is to provide a comprehensive overview of otorhinolaryngological complications during diving. With the increasing popularity of diving and the frequency of ear, nose, or throat-related injuries, it could be expected that these injuries will become more common and this review provides a resource for otorhinolaryngologists to diagnose and treat these conditions. PMID- 29450471 TI - Association of Childhood Infection With IQ and Adult Nonaffective Psychosis in Swedish Men: A Population-Based Longitudinal Cohort and Co-relative Study. AB - Importance: Associations between childhood infection, IQ, and adult nonaffective psychosis (NAP) are well established. However, examination of sensitive periods for exposure, effect of familial confounding, and whether IQ provides a link between childhood infection and adult NAP may elucidate pathogenesis of psychosis further. Objectives: To test the association of childhood infection with IQ and adult NAP, to find whether shared familial confounding explains the infection-NAP and IQ-NAP associations, and to examine whether IQ mediates and/or moderates the childhood infection-NAP association. Design, Setting, and Participants: Population-based longitudinal cohort study using linkage of Swedish national registers. The risk set included all Swedish men born between 1973 and 1992 and conscripted into the military until the end of 2010 (n = 771 698). We included 647 515 participants in the analysis. Measurement of Exposures: Hospitalization with any infection from birth to age 13 years. Main Outcomes and Measures: Hospitalization with an International Classification of Diseases diagnosis of NAP until the end of 2011. At conscription around age 18 years, IQ was assessed for all participants. Results: At the end of follow-up, the mean (SD) age of participants was 30.73 (5.3) years. Exposure to infections, particularly in early childhood, was associated with lower IQ (adjusted mean difference for infection at birth to age 1 year: -1.61; 95% CI, -1.74 to -1.47) and with increased risk of adult NAP (adjusted hazard ratio for infection at birth to age 1 year: 1.19; 95% CI, 1.06 to 1.33). There was a linear association between lower premorbid IQ and adult NAP, which persisted after excluding prodromal cases (adjusted hazard ratio per 1-point increase in IQ: 0.976; 95% CI, 0.974 to 0.978). The infection-NAP and IQ-NAP associations were similar in the general population and in full-sibling pairs discordant for exposure. The association between infection and NAP was both moderated (multiplicative, beta = .006; SE = 0.002; P = .02 and additive, beta = .008; SE = 0.002; P = .001) and mediated (beta = .028; SE = 0.002; P < .001) by IQ. Childhood infection had a greater association with NAP risk in the lower, compared with higher, IQ range. Conclusions and Relevance: Early childhood is a sensitive period for the effects of infection on IQ and NAP. The associations of adult NAP with early-childhood infection and adolescent IQ are not fully explained by shared familial factors and may be causal. Lower premorbid IQ in individuals with psychosis arises from unique environmental factors, such as early-childhood infection. Early-childhood infections may increase the risk of NAP by affecting neurodevelopment and by exaggerating the association of cognitive vulnerability with psychosis. PMID- 29450474 TI - Visual Field Progression Is More Complicated Than Meets the Eye. PMID- 29450473 TI - Elevated Blood Viscosity and Microrecirculation Resulting From Coronary Stent Malapposition. AB - One particular complexity of coronary artery is the natural tapering of the vessel with proximal segments having larger caliber and distal tapering as the vessel get smaller. The natural tapering of a coronary artery often leads to proximal incomplete stent apposition (ISA). ISA alters coronary hemodynamics and creates pathological path to develop complications such as in-stent restenosis, and more worryingly, stent thrombosis (ST). By employing state-of-the-art computer-aided design software, generic stent hoops were virtually deployed in an idealized tapered coronary artery with decreasing malapposition distance. Pulsatile blood flow simulations were carried out using computational fluid dynamics (CFD) on these computer-aided design models. CFD results reveal unprecedented details in both spatial and temporal development of microrecirculation environments throughout the cardiac cycle (CC). Arterial tapering also introduces secondary microrecirculation. These primary and secondary microrecirculations provoke significant fluctuations in arterial wall shear stress (WSS). There has been a direct correlation with changes in WSS and the development of atherosclerosis. Further, the presence of these microrecirculations influence strongly on the local levels of blood viscosity in the vicinity of the malapposed stent struts. The observation of secondary microrecirculations and changes in blood rheology is believed to complement the wall (-based) shear stress, perhaps providing additional physical explanations for tissue accumulation near ISA detected from high resolution optical coherence tomography (OCT).

PMID- 29450483 TI - Implementation Research: Embracing Practitioners' Views. AB - Purpose: This research explores practitioners' perspectives during the implementation of triadic gaze intervention (TGI), an evidence-based protocol for assessing and planning treatment targeting gaze as an early signal of intentional communication for young children with physical disabilities. Method: Using qualitative methods, 7 practitioners from 1 early intervention center reported their perceptions about (a) early intervention for young children with physical disabilities, (b) acceptability and feasibility in the use of the TGI protocol in routine practice, and (c) feasibility of the TGI training. Qualitative data were gathered from 2 semistructured group interviews, once before and once after TGI training and implementation. Results: Qualitative results documented the practitioners' reflections on recent changes to early intervention service delivery, the impact of such change on TGI adoption, and an overall strong enthusiasm for the TGI protocol, despite some need for adaptation. Conclusion: These results are discussed relative to adapting the TGI protocol and training, when considering how to best bring about change in practice. More broadly, results highlighted the critical role of researcher-practitioner collaboration in implementation research and the value of qualitative data for gaining a richer understanding of practitioners' perspectives about the implementation process. PMID- 29450485 TI - Error in Funding/Support. PMID- 29450484 TI - Neurological Manifestations Among US Government Personnel Reporting Directional Audible and Sensory Phenomena in Havana, Cuba. AB - Importance: From late 2016 through August 2017, US government personnel serving on diplomatic assignment in Havana, Cuba, reported neurological symptoms associated with exposure to auditory and sensory phenomena. Objective: To describe the neurological manifestations that followed exposure to an unknown energy source associated with auditory and sensory phenomena. Design, Setting, and Participants: Preliminary results from a retrospective case series of US government personnel in Havana, Cuba. Following reported exposure to auditory and sensory phenomena in their homes or hotel rooms, the individuals reported a similar constellation of neurological symptoms resembling brain injury. These individuals were referred to an academic brain injury center for multidisciplinary evaluation and treatment. Exposures: Report of experiencing audible and sensory phenomena emanating from a distinct direction (directional phenomena) associated with an undetermined source, while serving on US government assignments in Havana, Cuba, since 2016. Main Outcomes and Measures: Descriptions of the exposures and symptoms were obtained from medical record review of multidisciplinary clinical interviews and examinations. Additional objective assessments included clinical tests of vestibular (dynamic and static balance, vestibulo-ocular reflex testing, caloric testing), oculomotor (measurement of convergence, saccadic, and smooth pursuit eye movements), cognitive (comprehensive neuropsychological battery), and audiometric (pure tone and speech audiometry) functioning. Neuroimaging was also obtained. Results: Of 24 individuals with suspected exposure identified by the US Department of State, 21 completed multidisciplinary evaluation an average of 203 days after exposure. Persistent symptoms (>3 months after exposure) were reported by these individuals including cognitive (n = 17, 81%), balance (n = 15, 71%), visual (n = 18, 86%), and auditory (n = 15, 68%) dysfunction, sleep impairment (n = 18, 86%), and headaches (n = 16, 76%). Objective findings included cognitive (n = 16, 76%), vestibular (n = 17, 81%), and oculomotor (n = 15, 71%) abnormalities. Moderate to severe sensorineural hearing loss was identified in 3 individuals. Pharmacologic intervention was required for persistent sleep dysfunction (n = 15, 71%) and headache (n = 12, 57%). Fourteen individuals (67%) were held from work at the time of multidisciplinary evaluation. Of those, 7 began graduated return to work with restrictions in place, home exercise programs, and higher-level work-focused cognitive rehabilitation. Conclusions and Relevance: In this preliminary report of a retrospective case series, persistent cognitive, vestibular, and oculomotor dysfunction, as well as sleep impairment and headaches, were observed among US government personnel in Havana, Cuba, associated with reports of directional audible and/or sensory phenomena of unclear origin. These individuals appeared to have sustained injury to widespread brain networks without an associated history of head trauma. PMID- 29450486 TI - Differentiating Acute and Subacute Vertical Strabismus Using Different Head Positions During the Upright-Supine Test. AB - Importance: Accurate clinical differentiation between skew deviation and fourth nerve palsy (4NP) is critical in the acute and subacute settings. Objective: To determine the sensitivity and specificity of the upright-supine test to detect vertical misalignment changes using different head positions for the diagnosis of acute or subacute skew deviation vs 4NP. Design, Setting, and Participants: This multicenter study enrolled consecutive patients from Coimbra University Hospital Centre, Coimbra, Portugal, and Michigan State University, Lansing, within 2 months of presenting with vertical diplopia and diagnosed as having skew deviation or acquired unilateral 4NP. The study used nonmasked screening and diagnostic test results from June 1, 2013, to December 31, 2016. Data were analyzed from January 1, 2017, to June 30, 2017. Main Outcomes and Measures: A 50% or greater change in vertical misalignment between the upright and supine positions, with the head centered and tilted to either side. Measurements included the alternate prism and cover (APC) test, the double Maddox rod test, the APC test change index ([measurement upright - measurement supine] / [measurement upright + measurement supine]), and the APC test sensitivity and specificity. Results: Of the 37 included patients, the mean (SD) age was 58 (14) years, and 26 (70%) were male. We enrolled 19 patients (51%) with skew deviation and 18 (49%) with 4NP. Eighteen patients with skew deviation (95%) showed additional ocular motor and/or neurological signs. When moving to the supine position, only 1 patient with skew deviation (5%) showed more than a 50% decrease of hypertropia with the head centered (APC test: sensitivity, 5%; specificity, 100%). Three patients with 4NP (17%) showed more than a 50% decrease of hypertropia with the head tilted toward the hypertropic eye, and 10 patients with 4NP (56%) showed more than a 50% increase of hypertropia with the head tilted toward the hypotropic eye. Change indexes were different between the skew deviation and 4NP groups for head tilt to the hypotropic eye (difference, -0.33 prism diopters; 95% CI, -0.43 to -0.20; P < .001). Cyclotorsion worsened in the supine position only in patients with skew deviation (hypertropic eye: difference, -7.6 prism diopters; 95% CI, -13.00 to -0.75; P = .01; hypotropic eye: difference, 8.2 prism diopters; 95% CI, 0 to 15.75; P = .03). Conclusions and Relevance: The upright-supine test with the head centered is not a sensitive method to separate acute or subacute skew deviation from 4NP. Conversion of an incomitant vertical deviation in the upright position to a comitant vertical strabismus in the supine position in all head positions, as well as the absence of additional ocular motor and/or neurologic signs, may constitute a more useful clue. PMID- 29450487 TI - Systolic Blood Pressure and Outcomes in Patients With Heart Failure With Preserved Ejection Fraction. AB - Importance: Lower systolic blood pressure (SBP) levels are associated with poor outcomes in patients with heart failure. Less is known about this association in heart failure with preserved ejection fraction (HFpEF). Objective: To determine the associations of SBP levels with mortality and other outcomes in HFpEF. Design, Setting, and Participants: A propensity score-matched observational study of the Medicare-linked Organized Program to Initiate Lifesaving Treatment in Hospitalized Patients with Heart Failure (OPTIMIZE-HF) registry included 25 354 patients who were discharged alive; 8873 (35.0%) had an ejection fraction of at least 50%, and of these, 3915 (44.1%) had stable SBP levels (<=20 mm Hg admission to discharge variation). Data were collected from 259 hospitals in 48 states between March 1, 2003, and December 31, 2004. Data were analyzed from March 1, 2003, to December 31, 2008. Exposure: Discharge SBP levels less than 120 mm Hg. A total of 1076 of 3915 (27.5%) had SBP levels less than 120 mm Hg, of whom 901 (83.7%) were matched by propensity scores with 901 patients with SBP levels of 120 mm Hg or greater who were balanced on 58 baseline characteristics. Main Outcomes and Measures: Thirty-day, 1-year, and overall all-cause mortality and heart failure readmission through December 31, 2008. Results: The 1802 matched patients had a mean (SD) age of 79 (10) years; 1147 (63.7%) were women, and 134 (7.4%) were African American. Thirty-day all-cause mortality occurred in 91 (10%) and 45 (5%) of matched patients with discharge SBP of less than 120 mm Hg vs 120 mm Hg or greater, respectively (hazard ratio [HR], 2.07; 95% CI, 1.45-2.95; P < .001). Systolic blood pressure level less than 120 mm Hg was also associated with a higher risk of mortality at 1 year (39% vs 31%; HR, 1.36; 95% CI, 1.16-1.59; P < .001) and during a median follow-up of 2.1 (overall 6) years (HR, 1.17; 95% CI, 1.05-1.30; P = .005). Systolic blood pressure level less than 120 mm Hg was associated with a higher risk of heart failure readmission at 30 days (HR, 1.47; 95% CI, 1.08-2.01; P = .02) but not at 1 or 6 years. Hazard ratios for the combined end point of heart failure readmission or all-cause mortality associated with SBP level less than 120 mm at 30 days, 1 year, and overall were 1.71 (95% CI, 1.34-2.18; P < .001), 1.21 (95% CI, 1.07-1.38; P = .004), and 1.12 (95% CI, 1.01-1.24; P = .03), respectively. Conclusions and Relevance: Among hospitalized patients with HFpEF, an SBP level less than 120 mm Hg is significantly associated with poor outcomes. Future studies need to prospectively evaluate optimal SBP treatment goals in patients with HFpEF. PMID- 29450488 TI - Spatial Release From Masking in Adults With Bilateral Cochlear Implants: Effects of Distracter Azimuth and Microphone Location. AB - Purpose: The primary purpose of this study was to derive spatial release from masking (SRM) performance-azimuth functions for bilateral cochlear implant (CI) users to provide a thorough description of SRM as a function of target/distracter spatial configuration. The secondary purpose of this study was to investigate the effect of the microphone location for SRM in a within-subject study design. Method: Speech recognition was measured in 12 adults with bilateral CIs for 11 spatial separations ranging from -90 degrees to +90 degrees in 20 degrees steps using an adaptive block design. Five of the 12 participants were tested with both the behind-the-ear microphones and a T-mic configuration to further investigate the effect of mic location on SRM. Results: SRM can be significantly affected by the hemifield origin of the distracter stimulus-particularly for listeners with interaural asymmetry in speech understanding. The greatest SRM was observed with a distracter positioned 50 degrees away from the target. There was no effect of mic location on SRM for the current experimental design. Conclusion: Our results demonstrate that the traditional assessment of SRM with a distracter positioned at 90 degrees azimuth may underestimate maximum performance for individuals with bilateral CIs.

PMID- 29450493 TI - The Impact of Age, Background Noise, Semantic Ambiguity, and Hearing Loss on Recognition Memory for Spoken Sentences. AB - Purpose: The goal of this study was to determine how background noise, linguistic properties of spoken sentences, and listener abilities (hearing sensitivity and verbal working memory) affect cognitive demand during auditory sentence comprehension. Method: We tested 30 young adults and 30 older adults. Participants heard lists of sentences in quiet and in 8-talker babble at signal to-noise ratios of +15 dB and +5 dB, which increased acoustic challenge but left the speech largely intelligible. Half of the sentences contained semantically ambiguous words to additionally manipulate cognitive challenge. Following each list, participants performed a visual recognition memory task in which they viewed written sentences and indicated whether they remembered hearing the sentence previously. Results: Recognition memory (indexed by d') was poorer for acoustically challenging sentences, poorer for sentences containing ambiguous words, and differentially poorer for noisy high-ambiguity sentences. Similar patterns were observed for Z-transformed response time data. There were no main effects of age, but age interacted with both acoustic clarity and semantic ambiguity such that older adults' recognition memory was poorer for acoustically degraded high-ambiguity sentences than the young adults'. Within the older adult group, exploratory correlation analyses suggested that poorer hearing ability was associated with poorer recognition memory for sentences in noise, and better verbal working memory was associated with better recognition memory for sentences in noise. Conclusions: Our results demonstrate listeners' reliance on domain general cognitive processes when listening to acoustically challenging speech, even when speech is highly intelligible. Acoustic challenge and semantic ambiguity both reduce the accuracy of listeners' recognition memory for spoken sentences. Supplemental Materials: https://doi.org/10.23641/asha.5848059. PMID- 29450495 TI - Tutorial and Guidelines on Measurement of Sound Pressure Level in Voice and Speech. AB - Purpose: Sound pressure level (SPL) measurement of voice and speech is often considered a trivial matter, but the measured levels are often reported incorrectly or incompletely, making them difficult to compare among various studies. This article aims at explaining the fundamental principles behind these measurements and providing guidelines to improve their accuracy and reproducibility. Method: Basic information is put together from standards, technical, voice and speech literature, and practical experience of the authors and is explained for nontechnical readers. Results: Variation of SPL with distance, sound level meters and their accuracy, frequency and time weightings, and background noise topics are reviewed. Several calibration procedures for SPL measurements are described for stand-mounted and head-mounted microphones. Conclusions: SPL of voice and speech should be reported together with the mouth to-microphone distance so that the levels can be related to vocal power. Sound level measurement settings (i.e., frequency weighting and time weighting/averaging) should always be specified. Classified sound level meters should be used to assure measurement accuracy. Head-mounted microphones placed at the proximity of the mouth improve signal-to-noise ratio and can be taken advantage of for voice SPL measurements when calibrated. Background noise levels should be reported besides the sound levels of voice and speech.

AB - Importance: Multiple molecular signatures are available for managing estrogen receptor (ER)-positive breast cancer but with little direct comparative information to guide the patient's choice. Objective: To conduct a within-patient comparison of the prognostic value of 6 multigene signatures in women with early ER-positive breast cancer who received endocrine therapy for 5 years. Design, Setting, and Participants: This retrospective biomarker analysis included 774 postmenopausal women with ER-positive ERBB2 (formerly HER2)-negative breast cancer. This analysis was performed as a preplanned secondary study of data from the Anastrozole or Tamoxifen Alone or Combined randomized clinical trial comparing 5-year treatment with anastrozole vs tamoxifen with 10-year follow-up data. The signatures included the Oncotype Dx recurrence score, PAM50-based Prosigna risk of recurrence (ROR), Breast Cancer Index (BCI), EndoPredict (EPclin), Clinical Treatment Score, and 4-marker immunohistochemical score. Data were collected from January 2009, through April 2015. Main Outcomes and Measures: The primary objective was to compare the prognostic value of these signatures in addition to the Clinical Treatment Score (nodal status, tumor size, grade, age, and endocrine treatment) for distant recurrence for 0 to 10 years and 5 to 10 years after diagnosis. Likelihood ratio (LR) statistics were used with the chi2 test and C indexes to assess the prognostic value of each signature. Results: In this study of 774 postmenopausal women with ER-positive, ERBB2-negative disease (mean [SD] age, 64.1 [8.1] years), 591 (mean [SD] age, 63.4 [7.9] years) had node negative disease. The signatures providing the most prognostic information were the ROR (hazard ratio [HR], 2.56; 95% CI, 1.96-3.35), followed by the BCI (HR, 2.46; 95% CI, 1.88-3.23) and EPclin (HR, 2.14; 95% CI, 1.71-2.68). Each provided significantly more information than the Clinical Treatment Score (HR, 1.99; 95% CI, 1.58-2.50), the recurrence score (HR, 1.69; 95% CI, 1.40-2.03), and the 4 marker immunohistochemical score (HR, 1.95; 95% CI, 1.55-2.45). Substantially less information was provided by all 6 molecular tests for the 183 patients with 1 to 3 positive nodes, but the BCI (DeltaLR chi2 = 9.2) and EPclin (DeltaLR chi2 = 7.4) provided more additional prognostic information than the other signatures. Conclusions and Relevance: For women with node-negative disease, the ROR, BCI, and EPclin were significantly more prognostic for overall and late distant recurrence. For women with 1 to 3 positive nodes, limited independent information was available from any test. These data might help oncologists and patients to choose the most appropriate test when considering chemotherapy use and/or extended endocrine therapy.

AB - Importance: Each of the 5 diagnostic criteria or factors of metabolic syndrome hyperglycemia or type 2 diabetes, hypertension, obesity, elevated triglyceride levels, and decreased high-density lipoprotein cholesterol level-is associated with the pathophysiologic features of sudden sensorineural hearing loss (SSNHL). Little is known, however, about the association of metabolic syndrome, defined as the presence of at least 3 of these factors, with the prognosis of SSNHL. Objective: To evaluate the association of metabolic syndrome with the rate of recovery from SSNHL. Design, Setting, and Participants: This retrospective medical record review of 124 patients treated for SSNHL at a single tertiary university hospital was performed from June 1, 2014, through May 31, 2016. Medical records were reviewed for demographic and clinical characteristics and audiologic variables. Exposure: Sudden sensorineural hearing loss. Main Outcomes and Measures: Correlation among demographic and clinical characteristics, audiologic results, and prognosis. Results: Of the total 124 patients (52 men [41.9%]; 72 women [58.1%]; mean [SD] age, 56.0 [14.6] years), 70 had metabolic syndrome and 54 did not. Rates of type 2 diabetes (36 [51.4%] vs 6 [11.1%]; mean difference [MD], 40.3%; 95% CI, 24.4%-53.1%), hypertension (46 [65.7%] vs 9 [16.7%]; MD, 49.1%; 95% CI, 32.3%-61.7%), and obesity (47 [67.1%] vs 6 [11.1%]; MD%, 56.0; 95% CI, 40.0%-67.5%) and mean (SD) concentrations of triglycerides (192.9 [159.7] vs 133.4 [116.6] mg/dL; MD, 59.4 mg/dL; 95% CI, 53.0-65.9 mg/dL) were significantly higher and mean (SD) concentrations of high-density lipoprotein cholesterol (45.8 [9.4] vs 62.6 [17.7] mg/dL; MD, 16.8 mg/dL; 95% CI, 16.1-17.4 mg/dL) were significantly lower in the group with metabolic syndrome than in the group without metabolic syndrome. Mean (SD) pure-tone audiometry thresholds were similar at baseline in the groups with and without metabolic syndrome (65.0 [24.2] vs 60.8 [24.2] dB; MD, 4.3 dB; 95% CI, 3.2-5.4 dB), but recovery rates after treatment were significantly lower in the group with metabolic syndrome (16 [22.9%] vs 23 [42.6%]; MD, -19.7%; 95% CI, -35.4% to 3.2%). No differences were found in the 5 factors among patients with metabolic syndrome who did and did not recover. Level of hearing loss was higher in patients with than without metabolic syndrome, but the difference was not statistically significant. Audiogram patterns also differed but not significantly. Hearing recovery rates were similar in patients with 3 factors of metabolic syndrome and those with none but differed significantly between patients with 4 or more factors and those without metabolic syndrome (4 [19.0%] vs 27 [50.0%]; MD, -31.0%; 95% CI, -48.1% to -6.4%). Conclusions and Relevance: The rate of recovery from SSNHL was lower among patients with metabolic syndrome than among those without metabolic syndrome, and prognosis was poorer in patients with 4 or more diagnostic factors of the metabolic syndrome.

PMID- 29450497 TI - Detection of Glaucoma Progression in Individuals of African Descent Compared With Those of European Descent. AB - Importance: Individuals of African descent have been reported to be at higher risk for becoming visually impaired from glaucoma compared with individuals of European descent. Objective: To investigate racial differences in longitudinal visual field variability and their impact on time to detect visual field progression. Design, Setting, and Participants: This multicenter prospective observational cohort study included 236 eyes of 173 individuals of European descent and 235 eyes of 171 individuals of African descent followed up for a mean (SD) time of 7.5 (3.4) years. Main Outcomes and Measures: Differences in test retest variability and simulated time to detect progression in individuals of African descent and of European descent with glaucoma. Standard automated perimetry mean deviation values were regressed over time for each eye, and SD of the residuals was used as a measure of variability. Distributions of residuals were used in computer simulations to reconstruct "real-world" standard automated perimetry mean deviation trajectories under different assumptions about rate of change and frequency of testing. Times to detect progression were obtained for the simulated visual fields. Results: Among the 344 patients, the mean (SD) age at baseline was 60.2 (10.0) and 60.6 (9.0) years for individuals of African descent and of European descent, respectively; 94 (52%) and 86 (48%) of individuals of African descent and of European descent were women, respectively. The mean SD of the residuals was larger in eyes of individuals of African descent vs those of European descent (1.45 [0.83] dB vs 1.12 [0.48] dB; mean difference: 0.33 dB; 95% CI of the difference, 0.21-0.46; P < .001). The eyes in individuals of African descent had a larger increase in variability with worsening disease (P < .001). When simulations were performed assuming common progression scenarios, there was a delay to detect progression in eyes of individuals of African descent compared with those of European descent. For a scenario with baseline mean deviation of -10 dB and rate of change of -0.5 dB/y, detection of progression in individuals of African descent was delayed by 3.1 (95% CI, 2.9-3.2) years, when considered 80% power and annual tests. Conclusions and Relevance: Patients of African descent with glaucoma showed increased visual field variability compared with those of European descent, resulting in delayed detection of progression that may contribute to explain higher rates of glaucoma-related visual impairment in individuals of African descent compared with those of European descent with glaucoma. PMID- 29450499 TI - Otorhinolaryngology and Diving-Part 2: Otorhinolaryngological Fitness for Compressed Gas Scuba Diving: A Review. AB - Importance: Self-contained underwater breathing apparatus (scuba) diving has become increasingly popular with millions of people diving each year. Otorhinolaryngologists are often consulted either by patients or diving physicians regarding fitness to dive, and at present, the guidelines do not provide comprehensive information regarding the evaluation of this patient cohort. The aim of this review is to provide a comprehensive overview of existing otorhinolaryngological guidelines for fitness to dive recreationally. Observations: There is a paucity of guidelines for assessing otorhinolaryngological fitness to dive in the recreational diver. Comprehensive guidelines exist from US, European, and UK regulatory bodies regarding fitness for commercial diving; however, not all of these can be directly extrapolated to the recreational diver. There are also a variety of conditions that are not covered either by the existing fitness for recreational diving guidelines or the commercial regulatory bodies. Conclusions and Relevance: With the paucity of recreational fitness to dive guidelines we must draw on information from the commercial diving regulatory bodies. We have provided our own recommendations on the conditions that are not covered by either of the above, to provide otorhinolaryngologists with the information they require to assess fitness for recreational diving. PMID- 29450500 TI - Sixty Beats per Minute. PMID- 29450501 TI - Temporal estimation in prediction motion tasks is biased by a moving destination. AB - An ability to predict the time-to-contact (TTC) of moving objects that become momentarily hidden is advantageous in everyday life and could be particularly so in fast-ball sports. Prediction motion (PM) experiments have sought to test this ability using tasks where a disappearing target moves toward a stationary destination. Here, we developed two novel versions of the PM task in which the destination either moved away from (Chase) or toward (Attract) the moving target. The target and destination moved with different speeds such that collision occurred 750, 1,000 or 1,250 ms after target occlusion. To determine if domain specific experience conveys an advantage in PM tasks, we compared the performance of different sporting groups ranging from internationally competing athletes to non-sporting controls. There was no difference in performance between sporting groups and non-sporting controls but there were significant and independent effects on response error by target speed, destination speed, and occlusion period. We simulated these findings using a revised version of the linear TTC model of response timing for PM tasks (Yakimoff, Bocheva, & Mitrania, 1987; Yakimoff, Mateeff, Ehrenstein, & Hohnsbein, 1993) in which retinal input from the moving destination biases the internal representation of the occluded target. This revision closely reproduced the observed patterns of response error and thus describes a means by which the brain might estimate TTC when the target and destination are in motion. PMID- 29450503 TI - The Mechanical Contribution of Vimentin to Cellular Stress Generation. AB - Contractile stress generation by adherent cells is largely determined by the interplay of forces within their cytoskeleton. It is known that actin stress fibers, connected to focal adhesions, provide contractile stress generation, while microtubules and intermediate filaments provide cells compressive stiffness. Recent studies have shown the importance of the interplay between the stress fibers and the intermediate filament vimentin. Therefore, the effect of the interplay between the stress fibers and vimentin on stress generation was quantified in this study. We hypothesized that net stress generation comprises the stress fiber contraction combined with the vimentin resistance. We expected an increased net stress in vimentin knockout (VimKO) mouse embryonic fibroblasts (MEFs) compared to their wild-type (vimentin wild-type (VimWT)) counterparts, due to the decreased resistance against stress fiber contractility. To test this, the net stress generation by VimKO and VimWT MEFs was determined using the thin film method combined with sample-specific finite element modeling. Additionally, focal adhesion and stress fiber organization were examined via immunofluorescent staining. Net stress generation of VimKO MEFs was three-fold higher compared to VimWT MEFs. No differences in focal adhesion size or stress fiber organization and orientation were found between the two cell types. This suggests that the increased net stress generation in VimKO MEFs was caused by the absence of the resistance that vimentin provides against stress fiber contraction. Taken together, these data suggest that vimentin resists the stress fiber contractility, as hypothesized, thus indicating the importance of vimentin in regulating cellular stress generation by adherent cells. PMID- 29450502 TI - Poor Speech Perception Is Not a Core Deficit of Childhood Apraxia of Speech: Preliminary Findings. AB - Purpose: Childhood apraxia of speech (CAS) is hypothesized to arise from deficits in speech motor planning and programming, but the influence of abnormal speech perception in CAS on these processes is debated. This study examined speech perception abilities among children with CAS with and without language impairment compared to those with language impairment, speech delay, and typically developing peers. Method: Speech perception was measured by discrimination of synthesized speech syllable continua that varied in frequency (/dalpha/ /galpha/). Groups were classified by performance on speech and language assessments and compared on syllable discrimination thresholds. Within-group variability was also evaluated. Results: Children with CAS without language impairment did not significantly differ in syllable discrimination compared to typically developing peers. In contrast, those with CAS and language impairment showed significantly poorer syllable discrimination abilities compared to children with CAS only and typically developing peers. Children with speech delay and language impairment also showed significantly poorer discrimination abilities, with appreciable within-group variability. Conclusions: These findings suggest that speech perception deficits are not a core feature of CAS but rather occur with co-occurring language impairment in a subset of children with CAS. This study establishes the significance of accounting for language ability in children with CAS. Supplemental Materials: https://doi.org/10.23641/asha.5848056.

PMID- 29450504 TI - Association of Adenotonsillectomy With Blood Pressure Among Hypertensive and Nonhypertensive Children With Obstructive Sleep Apnea. AB - Importance: Hypertension in childhood may continue into adulthood and lead to adverse cardiovascular outcomes. Evidence suggests that adenotonsillectomy for childhood obstructive sleep apnea (OSA) may be associated with blood pressure (BP) improvement. However, how adenotonsillectomy is associated with BP in hypertensive and nonhypertensive children with OSA remains unclear. Objective: To investigate disparities in BP changes after adenotonsillectomy in hypertensive and nonhypertensive children with OSA. Design, Setting, and Participants: From January 1, 2010, to April 30, 2016, children (aged <18 years) with symptoms of OSA treated at National Taiwan University Hospital were enrolled in this retrospective case series study. Interventions: Children underwent polysomnography for diagnosis of OSA (apnea-hypopnea index >1). All children with OSA underwent adenotonsillectomy. Main Outcomes and Measures: Preoperative and postoperative overnight polysomnographic data were obtained. Office BP was measured in a sleep center before (nocturnal BP) and after (morning) polysomnography. Results: A total of 240 nonobese children (mean [SD] age, 7.3 [3.0] years; 160 [66.7%] male and 80 [33.3%] female) with OSA were recruited. Postoperatively, the apnea-hypopnea index decreased significantly from 12.1 to 1.7 events per hour (95% CI of difference, -12.3 to -8.4 events per hour). The whole cohort had a significant decrease in nocturnal diastolic BP (66.9 to 64.5 mm Hg; 95% CI of difference, -4.1 to -0.7 mm Hg) and morning diastolic BP (66.9 to 64.4 mm Hg; 95% CI of difference, -4.2 to -0.8 mm Hg). The number (percentage) of patients with diastolic BP in the greater than 95th percentile decreased significantly nocturnally (48 [20.0%] to 33 [13.8%]; 95% CI of difference, -12.1% to -0.4%) and in the morning (52 [21.7%] to 34 [14.2%]; 95% CI of difference, 13.6% to -1.4%). Postoperatively, hypertensive children had a significant decrease in all BP measures, including mean (SD) nocturnal and morning systolic BP (nocturnal: 107.5 [8.6] mm Hg; morning: 106.0 [9.4] mm Hg), systolic BP index (nocturnal: -4.3 [8.6]; morning: -5.7 [8.5]), diastolic BP (nocturnal: 65.1 [11.5] mm Hg; morning: 64.4 [10.1] mm Hg), and diastolic BP index (nocturnal: 10.7 [17.3]; morning: -11.6 [15.7]), whereas the nonhypertensive group had a slight increase in nocturnal systolic BP (103.8 to 105.9 mm Hg; 95% CI of difference, 0.4-3.9 mm Hg). A generalized estimating equation model for subgroup comparisons revealed that children with hypertension, compared with those without, had greater improvement in all BP measures. Conclusions and Relevance: Hypertensive children with OSA had a significant improvement in BP after adenotonsillectomy. Hypertensive children with OSA should be screened and treated by adenotonsillectomy because proper treatment not only eases OSA symptoms but also potentially prevents future cardiovascular and end-organ disease.

PMID- 29450523 TI - Effect of the Pulmonary Embolism Rule-Out Criteria on Subsequent Thromboembolic Events Among Low-Risk Emergency Department Patients: The PROPER Randomized Clinical Trial. AB - Importance: The safety of the pulmonary embolism rule-out criteria (PERC), an 8 item block of clinical criteria aimed at ruling out pulmonary embolism (PE), has not been assessed in a randomized clinical trial. Objective: To prospectively validate the safety of a PERC-based strategy to rule out PE. Design, Setting, and Patients: A crossover cluster-randomized clinical noninferiority trial in 14 emergency departments in France. Patients with a low gestalt clinical probability of PE were included from August 2015 to September 2016, and followed up until December 2016. Interventions: Each center was randomized for the sequence of intervention periods. In the PERC period, the diagnosis of PE was excluded with no further testing if all 8 items of the PERC rule were negative. Main Outcomes and Measures: The primary end point was the occurrence of a thromboembolic event during the 3-month follow-up period that was not initially diagnosed. The noninferiority margin was set at 1.5%. Secondary end points included the rate of computed tomographic pulmonary angiography (CTPA), median length of stay in the emergency department, and rate of hospital admission. Results: Among 1916 patients who were cluster-randomized (mean age 44 years, 980 [51%] women), 962 were assigned to the PERC group and 954 were assigned to the control group. A total of 1749 patients completed the trial. A PE was diagnosed at initial presentation in 26 patients in the control group (2.7%) vs 14 (1.5%) in the PERC group (difference, 1.3% [95% CI, -0.1% to 2.7%]; P = .052). One PE (0.1%) was diagnosed during follow-up in the PERC group vs none in the control group (difference, 0.1% [95% CI, -infinity to 0.8%]). The proportion of patients undergoing CTPA in the PERC group vs control group was 13% vs 23% (difference, 10% [95% CI, -13% to -6%]; P < .001). In the PERC group, rates were significantly reduced for the median length of emergency department stay (mean reduction, 36 minutes [95% CI, 4 to 68]) and hospital admission (difference, 3.3% [95% CI, 0.1% to 6.6%]). Conclusions and Relevance: Among very low-risk patients with suspected PE, randomization to a PERC strategy vs conventional strategy did not result in an inferior rate of thromboembolic events over 3 months. These findings support the safety of PERC for very low-risk patients presenting to the emergency department. Trial Registration: clinicaltrials.gov Identifier: NCT02375919. PMID- 29450524 TI - Effect of a Quality Improvement Intervention on Clinical Outcomes in Patients in India With Acute Myocardial Infarction: The ACS QUIK Randomized Clinical Trial. AB - Importance: Wide heterogeneity exists in acute myocardial infarction treatment and outcomes in India. Objective: To evaluate the effect of a locally adapted quality improvement tool kit on clinical outcomes and process measures in Kerala, a southern Indian state. Design, Setting, and Participants: Cluster randomized, stepped-wedge clinical trial conducted between November 10, 2014, and November 9, 2016, in 63 hospitals in Kerala, India, with a last date of follow-up of December 31, 2016. During 5 predefined steps over the study period, hospitals were randomly selected to move in a 1-way crossover from the control group to the intervention group. Consecutively presenting patients with acute myocardial infarction were offered participation. Interventions: Hospitals provided either usual care (control group; n = 10 066 participants [step 0: n = 2915; step 1: n = 2649; step 2: n = 2251; step 3: n = 1422; step 4; n = 829; step 5: n = 0]) or care using a quality improvement tool kit (intervention group; n = 11 308 participants [step 0: n = 0; step 1: n = 662; step 2: n = 1265; step 3: n = 2432; step 4: n = 3214; step 5: n = 3735]) that consisted of audit and feedback, checklists, patient education materials, and linkage to emergency cardiovascular care and quality improvement training. Main Outcomes and Measures: The primary outcome was the composite of all-cause death, reinfarction, stroke, or major bleeding using standardized definitions at 30 days. Secondary outcomes included the primary outcome's individual components, 30-day cardiovascular death, medication use, and tobacco cessation counseling. Mixed-effects logistic regression models were used to account for clustering and temporal trends. Results: Among 21 374 eligible randomized participants (mean age, 60.6 [SD, 12.0] years; n = 16 183 men [76%] ; n = 13 689 [64%] with ST-segment elevation myocardial infarction), 21 079 (99%) completed the trial. The primary composite outcome was observed in 5.3% of the intervention participants and 6.4% of the control participants. The observed difference in 30-day major adverse cardiovascular event rates between the groups was not statistically significant after adjustment (adjusted risk difference, -0.09% [95% CI, -1.32% to 1.14%]; adjusted odds ratio, 0.98 [95% CI, 0.80-1.21]). The intervention group had a higher rate of medication use including reperfusion but no effect on tobacco cessation counseling. There were no unexpected adverse events reported. Conclusions and Relevance: Among patients with acute myocardial infarction in Kerala, India, use of a quality improvement intervention compared with usual care did not decrease a composite of 30-day major adverse cardiovascular events. Further research is needed to understand the lack of efficacy. Trial Registration: clinicaltrials.gov Identifier: NCT02256657. PMID- 29450526 TI - Screening for Ovarian Cancer.

AB - Importance: The effect of the Affordable Care Act (ACA) dependent coverage provision on pregnancy-related health care and health outcomes is unknown. Objective: To determine whether the dependent coverage provision was associated with changes in payment for birth, prenatal care, and birth outcomes. Design, Setting, and Participants: Retrospective cohort study, using a differences-in differences analysis of individual-level birth certificate data comparing live births among US women aged 24 to 25 years (exposure group) and women aged 27 to 28 years (control group) before (2009) and after (2011-2013) enactment of the dependent coverage provision. Results were stratified by marital status. Main Exposures: The dependent coverage provision of the ACA, which allowed young adults to stay on their parent's health insurance until age 26 years. Main Outcomes and Measures: Primary outcomes were payment source for birth, early prenatal care (first visit in first trimester), and adequate prenatal care (a first trimester visit and 80% of expected visits). Secondary outcomes were cesarean delivery, premature birth, low birth weight, and infant neonatal intensive care unit (NICU) admission. Results: The study population included 1 379 005 births among women aged 24-25 years (exposure group; 299 024 in 2009; 1 079 981 in 2011-2013), and 1 551 192 births among women aged 27-28 years (control group; 325 564 in 2009; 1 225 628 in 2011-2013). From 2011-2013, compared with 2009, private insurance payment for births increased in the exposure group (36.9% to 35.9% [difference, -1.0%]) compared with the control group (52.4% to 51.1% [difference, -1.3%]), adjusted difference-in-differences, 1.9 percentage points (95% CI, 1.6 to 2.1). Medicaid payment decreased in the exposure group (51.6% to 53.6% [difference, 2.0%]) compared with the control group (37.4% to 39.4% [difference, 1.9%]), adjusted difference-in-differences, -1.4 percentage points (95% CI, -1.7 to -1.2). Self-payment for births decreased in the exposure group (5.2% to 4.3% [difference, -0.9%]) compared with the control group (4.9% to 4.3% [difference, -0.5%]), adjusted difference-in-differences, -0.3 percentage points (95% CI, -0.4 to -0.1). Early prenatal care increased from 70% to 71.6% (difference, 1.6%) in the exposure group and from 75.7% to 76.8% (difference, 0.6%) in the control group (adjusted difference-in-differences, 0.6 percentage points [95% CI, 0.3 to 0.8]). Adequate prenatal care increased from 73.5% to 74.8% (difference, 1.3%) in the exposure group and from 77.5% to 78.8% (difference, 1.3%) in the control group (adjusted difference-in-differences, 0.4 percentage points [95% CI, 0.2 to 0.6]). Preterm birth decreased from 9.4% to 9.1% in the exposure group (difference, -0.3%) and from 9.1% to 8.9% in the control group (difference, -0.2%) (adjusted difference-in-differences, -0.2 percentage points (95% CI, -0.3 to -0.03). Overall, there were no significant changes in low birth weight, NICU admission, or cesarean delivery. In stratified analyses, changes in payment for birth, prenatal care, and preterm birth were concentrated among unmarried women. Conclusions and Relevance: In this study of nearly 3 million births among women aged 24 to 25 years vs those aged 27 to 28 years, the Affordable Care Act dependent coverage provision was associated with increased private insurance payment for birth, increased use of prenatal care, and modest reduction in preterm births, but was not associated with changes in cesarean delivery rates, low birth weight, or NICU admission. PMID- 29450530 TI - Screening for Ovarian Cancer: Updated Evidence Report and Systematic Review for the US Preventive Services Task Force. AB - Importance: Ovarian cancer is relatively rare but the fifth-leading cause of cancer mortality among United States women. Objective: To systematically review evidence on benefits and harms of ovarian cancer screening among average-risk women to inform the United States Preventive Services Task Force. Data Sources: MEDLINE, PubMed, Cochrane Collaboration Registry of Controlled Trials; studies published in English from January 1, 2003, through January 31, 2017; ongoing surveillance in targeted publications through November 22, 2017. Study Selection: Randomized clinical trials of ovarian cancer screening in average-risk women that reported mortality or quality-of-life outcomes. Interventions included transvaginal ultrasound, cancer antigen 125 (CA-125) testing, or their combination. Comparators were usual care or no screening. Data Extraction and Synthesis: Independent critical appraisal and data abstraction by 2 reviewers. Meta-analytic pooling of results was not conducted because of the small number of studies and heterogeneity of interventions. Main Outcomes and Measures: Ovarian cancer mortality, false-positive screening results and surgery, surgical complications, and psychological effects of screening. Results: Four trials (N = 293 587) were included; of these, 3 (n = 293 038) assessed ovarian cancer mortality, and 1 (n = 549) reported only on psychological outcomes. Evaluated screening interventions included transvaginal ultrasound alone, transvaginal ultrasound plus CA-125 testing, and CA-125 testing alone. Test positivity for CA 125 was defined by a fixed serum level cutpoint or by a proprietary risk algorithm based on CA-125 level, change in CA-125 level over time, and age (risk of ovarian cancer algorithm [ROCA]). No trial found a significant difference in ovarian cancer mortality with screening. In the 2 large screening trials (PLCO and UKCTOCS, n = 271 103), there was not a statistically significant difference in complete intention-to-screen analyses of ovarian, fallopian, and peritoneal cancer cases associated with screening (PLCO: rate ratio, 1.18 [95% CI, 0.82 1.71]; UKCTOCS: hazard ratio [HR], 0.91 [95% CI, 0.76-1.09] for transvaginal ultrasound and HR, 0.89 [95% CI, 0.74-1.08] for CA-125 ROCA). Within these 2 trials, screening led to surgery for suspected ovarian cancer in 1% of women without cancer for CA-125 ROCA and in 3% for transvaginal ultrasound with or without CA-125 screening, with major complications occurring among 3% to 15% of surgery. Evidence on psychological harms was limited but nonsignificant except in the case of repeat follow-up scans and tests, which increased the risk of psychological morbidity in a subsample of UKCTOCS participants based on the General Health Questionnaire 12 (score >=4) (odds ratio, 1.28 [95% CI, 1.18 1.39]). Conclusions and Relevance: In randomized trials conducted among average risk, asymptomatic women, ovarian cancer mortality did not significantly differ between screened women and those with no screening or in usual care. Screening harms included surgery (with major surgical complications) in women found to not have cancer. Further research is needed to identify effective approaches for reducing ovarian cancer incidence and mortality. PMID- 29450532 TI - State Restrictions of e-Cigarette Use Has Slowed.

AB - Importance: With approximately 14 000 deaths per year, ovarian cancer is the fifth most common cause of cancer death among US women and the leading cause of death from gynecologic cancer. More than 95% of ovarian cancer deaths occur among women 45 years and older. Objective: To update the 2012 US Preventive Services Task Force (USPSTF) recommendation on screening for ovarian cancer. Evidence Review: The USPSTF reviewed the evidence on the benefits and harms of screening for ovarian cancer in asymptomatic women not known to be at high risk for ovarian cancer (ie, high risk includes women with certain hereditary cancer syndromes that increase their risk for ovarian cancer). Outcomes of interest included ovarian cancer mortality, quality of life, false-positive rate, surgery and surgical complication rates, and psychological effects of screening. Findings: The USPSTF found adequate evidence that screening for ovarian cancer does not reduce ovarian cancer mortality. The USPSTF found adequate evidence that the harms from screening for ovarian cancer are at least moderate and may be substantial in some cases, and include unnecessary surgery for women who do not have cancer. Given the lack of mortality benefit of screening, and the moderate to substantial harms that could result from false-positive screening test results and subsequent surgery, the USPSTF concludes with moderate certainty that the harms of screening for ovarian cancer outweigh the benefit, and the net balance of the benefit and harms of screening is negative. Conclusions and Recommendation: The USPSTF recommends against screening for ovarian cancer in asymptomatic women. (D recommendation) This recommendation applies to asymptomatic women who are not known to have a high-risk hereditary cancer syndrome.

AB - Purpose: The visual Text Reception Threshold (TRT) test (Zekveld et al., 2007) has been designed to assess modality-general factors relevant for speech perception in noise. In the last decade, the test has been adopted in audiology labs worldwide. The 1st aim of this study was to examine which factors best predict interindividual differences in the TRT. Second, we aimed to assess the relationships between the TRT and the speech reception thresholds (SRTs) estimated in various conditions. Method: First, we reviewed studies reporting relationships between the TRT and the auditory and/or cognitive factors and formulated specific hypotheses regarding the TRT predictors. These hypotheses were tested using a prediction model applied to a rich data set of 180 hearing aid users. In separate association models, we tested the relationships between the TRT and the various SRTs and subjective hearing difficulties, while taking into account potential confounding variables. Results: The results of the prediction model indicate that the TRT is predicted by the ability to fill in missing words in incomplete sentences, by lexical access speed, and by working memory capacity. Furthermore, in line with previous studies, a moderate association between higher age, poorer pure-tone hearing acuity, and poorer TRTs was observed. Better TRTs were associated with better SRTs for the correct perception of 50% of Hagerman matrix sentences in a 4-talker babble, as well as with better subjective ratings of speech perception. Age and pure-tone hearing thresholds significantly confounded these associations. The associations of the TRT with SRTs estimated in other conditions and with subjective qualities of hearing were not statistically significant when adjusting for age and pure-tone average. Conclusions: We conclude that the abilities tapped into by the TRT test include processes relevant for speeded lexical decision making when completing partly masked sentences and that these processes require working memory capacity. Furthermore, the TRT is associated with the SRT of hearing aid users as estimated in a challenging condition that includes informational masking and with experienced difficulties with speech perception in daily-life conditions. The current results underline the value of using the TRT test in studies involving speech perception and aid in the interpretation of findings acquired using the test. PMID- 29450535 TI - A Spatiotemporal Requirement for Prickle 1-Mediated PCP Signaling in Eyelid Morphogenesis and Homeostasis. AB - Purpose: Tissue closure/fusion is a fundamental process during organogenesis, driven in part by the Wnt/planar cell polarity (Wnt/PCP) pathway. This study explored the spatial and temporal aspects of PCP signaling in eyelid development through analysis of mice lacking Prickle 1, a core PCP component, and the Prickle1-dependent signaling networks underlying eyelid development. Methods: Wild type and Prickle 1 compound mutant mice with a hypomorphic and a null allele were bred and used to study eyelid morphogenesis. The time course of embryonic eyelid fusion and postnatal reopening was examined by light microscopy of tissue sections and scanning electron microscopy. Immunohistochemistry was conducted to monitor cell proliferation, death, and molecular identities through pre- and postnatal eyelid development. Results: Prickle 1 mutant embryos exhibited a profound delay in eyelid closure at embryonic ages, but manifested precocious eyelid reopening postnatally, with ensuing cornea malformation. Mutant embryonic showed downregulation of phosphorylated c-Jun, and upregulation of increased beta catenin in separate cell populations of the eyelid front area. Increased cell death and decreased mesenchymal infiltration was observed in postnatal mutant eyelid prior to eyelid reopening. While broadly expressed in many tissues, Prickle 1 was spatially restricted to the eyelid front at E15.5, a location where c-Jun and beta-catenin expression was altered in Prickle 1 mutants. Conclusions: The study demonstrates a spatiotemporal requirement for Prickle 1-mediated PCP signaling during eyelid morphogenesis and homeostasis. The study links Prickle 1 mediated PCP signaling to existing networks, and provides a useful animal model for studying congenital ocular surface diseases. PMID- 29450536 TI - Administration of Nitric Oxide Through a Novel Copper-Chitosan Delivery System in Human Corneal and Limbal Epithelial Cell Injury. AB - Purpose: Nitric oxide (NO) has gained attention for its role in facilitating wound healing by promoting cell migration, while being cytoprotective in a variety of cell types. We determined the efficacy of NO, administered using a novel application of copper-chitosan treatments (Cu-Ch), in facilitating corneal epithelial wound healing using an in vitro model of corneal epithelial and limbal epithelial cell injury. Methods: Human corneal epithelial (HCE) and human limbal epithelial (HLE) cells were monitored under no-scratch (CON), untreated scratch (CS), scratch + plain chitosan composite (0%), scratch + 1% copper solution Cu-Ch (1%), and scratch + 2% copper solution Cu-Ch (2%) conditions. Cell migration, cytotoxicity, apoptosis, and total nitrate/nitrite concentrations were measured at 24, 48, and 72 hours after injury and treatment. iNOS expression in HLE cells also was determined using Western blot. Results: Wound closure significantly increased in HCE cells treated with Cu-Ch (1% and 2%) after 72 hours, while HLE cells showed a significant decrease in closure with Cu-Ch (1% and 2%) treatment compared to CS. Cytotoxic fragments decreased significantly with 1% and 2% Cu-Ch treatments in HCE cells. Nitrate/nitrite levels in HLE cells showed a significant increase with 2% Cu-Ch treatment compared to CS. This increase is complemented with an upregulation of iNOS. Conclusions: Overall, HCE wound healing was accelerated with administration of Cu-Ch treatment. Differences between HCE and HLE responses may be due to intrinsic differences in NO metabolism, as evidenced by differences in NO production, potentially caused by differences in iNOS expression with treatment. PMID- 29450537 TI - Enhanced Expression of NLRP3 Inflammasome-Related Inflammation in Diabetic Retinopathy. AB - Purpose: The aim of this study was to determine the association between nucleotide-binding and oligomerization domain (NOD)-like receptors (NLRs) family, pyrin domain-containing 3 (NLRP3) inflammasome-induced inflammation and disease severity in diabetic retinopathy (DR). Methods: Blood samples were collected from 64 patients with diabetes (DR, 43; without DR, 21) and 25 healthy controls. The protein and mRNA expression levels of NLRP3 inflammasomes in peripheral blood mononuclear cells were determined using western blotting and quantitative real time reverse transcription-PCR. A total of 82 vitreous samples were obtained from patients with DR (n = 60) and nondiabetic controls (n = 22). All patients were candidates for vitrectomy. Interleukin (IL)-1beta and IL-18 in the peripheral blood mononuclear cell culture medium and vitreous fluid were detected by enzyme linked immunosorbent assay (ELISA). Immunofluorescence staining for apoptosis associated speck-like protein with a caspase recruitment domain (ASC) and NLRP3 was performed in fibrovascular membranes from 21 proliferative DR patients and 22 controls with idiopathic epiretinal membranes. Results: We observed increased gene and protein expression of NLRP3, ASC, and caspase-1 in peripheral blood mononuclear cells of adults with DR compared with that in normal controls. Furthermore, the elevated expressions of NLRP3 and ASC were observed in the fibrovascular membranes from 21 adults with proliferative DR when compared with the 22 controls. IL-1beta and IL-18 in the peripheral blood mononuclear cells and vitreous fluid were elevated in the DR patients when compared with controls. Conclusions: These outcomes suggested that NLRP3 inflammasomes are upregulated in adults with DR and may play a key role in the pathogenesis and progression of DR. PMID- 29450539 TI - Retinothalamic White Matter Abnormalities in Amblyopia. AB - Purpose: Amblyopia is associated with a broad array of perceptual and neural abnormalities in the visual system, particularly in untreated or unsuccessfully treated populations. Traditionally, it has been believed that the neural abnormalities are confined to the visual cortex and subcortex (e.g., lateral geniculate nucleus). Here, we investigate the presence of neuroanatomical abnormalities earlier in the visual stream, in the optic nerves and tracts, of participants with two predominant forms of amblyopia. Methods: We used diffusion magnetic resonance imaging and probabilistic tractography to compare the microstructural properties of five white matter visual pathways between 15 participants with amblyopia (eight anisometropic, five strabismic, and two exhibiting both etiologies), and 13 age-matched controls. Results: Participants with amblyopia exhibited significantly smaller mean fractional anisotropy in the optic nerve and optic tract (0.26 and 0.31 vs. 0.31 and 0.36 in controls, respectively). We also found greater mean diffusivity in the optic radiation compared to controls (0.72 MUm2/s vs. 0.68 MUm2/s, respectively). Comparing etiologies, the abnormalities in the precortical pathways tended to be more severe in participants with anisometropic compared to strabismic amblyopia, and anisometropic participants' optic nerves, optic tracts, and optic radiations significantly differed from control participants' (all, P < 0.05). Conclusions: The results indicate that amblyopia may be associated with microstructural abnormalities in neural networks as early as the retina, and these abnormalities may differ between amblyopic etiologies. PMID- 29450538 TI - Clinical Age-Specific Seasonal Conjunctivitis Patterns and Their Online Detection in Twitter, Blog, Forum, and Comment Social Media Posts. AB - Purpose: We sought to determine whether big data from social media might reveal seasonal trends of conjunctivitis, most forms of which are nonreportable. Methods: Social media posts (from Twitter, and from online forums and blogs) were classified by age and by conjunctivitis type (allergic or infectious) using Boolean and machine learning methods. Based on spline smoothing, we estimated the circular mean occurrence time (a measure of central tendency for occurrence) and the circular variance (a measure of uniformity of occurrence throughout the year, providing an index of seasonality). Clinical records from a large tertiary care provider were analyzed in a similar way for comparison. Results: Social media posts machine-coded as being related to infectious conjunctivitis showed similar times of occurrence and degree of seasonality to clinical infectious cases, and likewise for machine-coded allergic conjunctivitis posts compared to clinical allergic cases. Allergic conjunctivitis showed a distinctively different seasonal pattern than infectious conjunctivitis, with a mean occurrence time later in the spring. Infectious conjunctivitis for children showed markedly greater seasonality than for adults, though the occurrence times were similar; no such difference for allergic conjunctivitis was seen. Conclusions: Social media posts broadly track the seasonal occurrence of allergic and infectious conjunctivitis, and may be a useful supplement for epidemiologic monitoring. PMID- 29450540 TI - Endocan Blockade Suppresses Experimental Ocular Neovascularization in Mice. AB - Purpose: Ocular neovascularization (NV) is a pathologic process characterized by the proliferation and infiltration of various types of cells such as RPE, glial, and endothelial cells, which interact with proangiogenic factors and inflammatory cytokines. Endocan is known to be enriched in retinal endothelial tip cells under hypoxia, but the effect of endocan on ocular NV progression is largely unknown. In this study, we investigated the role of endocan in the ocular NV pathologic process and the possible mechanisms involved. Methods: In the eyes of mice with oxygen-induced retinopathy (OIR); choroidal NV (CNV); and rhodopsin promoter (rho)/VEGF transgenic mice, endocan expression was assessed by quantitative real time PCR (RT-PCR) and Western blot. In vivo, a specific functional antibody was used to neutralize endocan and ocular NV levels were evaluated by RT-PCR, Western blot and immunostaining of flat-mounts. In vitro, the effect of endocan on human retinal microvascular endothelial cell (HREC) tube formation was observed using a routine method. Results: Endocan was significantly elevated in these three experimental mice models. Endocan blockade with the neutralizer intravitreal injection not only suppressed the area of retinal, choroidal and subretinal NV, but also resulted in a decrease in several angiogenesis-associated molecules. Recombinant endocan protein (rhEndocan) was found to induce tube formation on HRECs directly. Conclusions: The current data suggest that endocan is a potential therapeutic or an additional target for retinal and subretinal NV diseases. PMID- 29450541 TI - Induction of Ocular Complement Activation by Inflammatory Stimuli and Intraocular Inhibition of Complement Factor D in Animal Models. AB - Purpose: Genome-wide association studies suggest a role for the complement system in age-related macular degeneration (AMD). We characterized ocular complement activation and evaluated a complement factor D (FD) neutralizing antibody. Methods: Mice were treated with toll-like receptor (TLR) ligands, intravitreal injection (IVT), or corneal debridement. Levels of complement proteins and mRNA were measured. A FD neutralizing antibody was administered IVT into eyes of rabbits that were challenged with LPS (lipopolysaccharide) administered intravenously. Results: Levels of C3 and factor B (FB) mRNA and protein in the eye were increased following intraperitoneal injection of TLR4 ligand LPS. Increased levels of C3 and FB breakdown products were observed in both eye tissues and plasma. Complement activation products were markedly reduced in C3-/- and Cfb-/- mice challenged with LPS. Ocular complement levels were also elevated in mice treated systemically with TLR2 and -3 ligands, injured by IVT injection or corneal debridement, or even in normal aging. IVT administration of a complement FD neutralizing antibody in rabbits inhibited LPS-induced complement activation in the posterior segment of the eye, but not in the anterior segment of the eye or in plasma. Conclusions: Systemic TLR stimulation and eye tissue injury induced time-dependent alternative complement pathway activation in the eye. Ocular complement levels were also gradually elevated during aging. An anti FD antibody IVT potently inhibited LPS-induced complement activation in the posterior segment of the eye. This study provides insights into the dynamic profile of ocular complement activation, which is valuable for complement research in eye diseases and for developing complement therapeutics for AMD. PMID- 29450542 TI - Optical Properties Influence Visual Cortical Functional Resolution After Cataract Surgery and Both Dissociate From Subjectively Perceived Quality of Vision. AB - Purpose: To investigate the relation between optical properties, population receptive fields (pRFs), visual function, and subjectively perceived quality of vision after cataract surgery. Methods: The study includes 30 patients who had recently undergone bilateral sequential cataract surgery. We used functional magnetic resonance imaging and pRF modelling methods to assess pRF sizes across visual cortical regions (V1-V3). Subjects also performed a complete ophthalmologic and psychophysical examination and answered a quality of vision questionnaire. Results: Subjects with worse optical properties had, as predicted, larger pRF sizes. In addition, analysis in the primary visual cortex revealed significantly larger mean pRF sizes for operated subjects with worse contrast sensitivity (P = 0.038). In contrast, patients who scored high in the subjective "bothersome" dimension induced by dysphotic symptoms had surprisingly lower pRF size fitting interception (P = 0.012) and pRF size fitting slopes (P = 0.020), suggesting a dissociation between objective quality of vision and subjective appraisal. Conclusions: Optical properties of the eye influence pRF size. In particular, visual aberrations have a negative impact on visual cortical processing. A novel dissociation between subjective reports of quality of vision and pRF sizes was further identified. This suggests that patients with better cortical resolution may have a negative subjective response possibly because of improved perception of dysphotic phenomena. pRF properties represent a valuable quantitative measure to objectively evaluate quality of vision but do not necessarily predict subjective complaints. PMID- 29450543 TI - Mutation in the Zebrafish cct2 Gene Leads to Abnormalities of Cell Cycle and Cell Death in the Retina: A Model of CCT2-Related Leber Congenital Amaurosis. AB - Purpose: The compound heterozygous mutations in the beta subunit of chaperonin containing TCP-1 (CCT), encoded by CCT2, lead to the Leber congenital amaurosis (LCA). In this study, a cct2 mutant line of zebrafish was established to investigate the role of CCT2 mutations in LCA in vertebrates. Methods: A cct2 mutant zebrafish line was produced using the CRISPR-Cas9 system. Changes in the eyes of developing wild-type and mutant larvae were monitored using microscopy, immunostaining, TUNEL, and EdU assays. Phenotypic rescue of mutant phenotype was investigated by injection of CCT2 RNA into zebrafish embryos. Results: The cct2 mutation (L394H-7del) led to the synthesis of a mutated cctbeta protein with the L394H replacement and deletion of 7 amino acid residues (positions 395-401). The homozygous cct2-L394H-7del mutant exhibited a small eye phenotype at 2 days post fertilization (dpf) and was embryonically lethal after 5 dpf. In homozygous cct2 L394H-7del mutants, the retinal ganglion cell differentiation was attenuated, retinal cell cycle was affected, and the neural retinal cell death was significantly increased at 2 dpf compared with wild-type. Injection of RNA encoding wild-type human CCTbeta rescued the small eye phenotype, reduced retinal cell death, and restored the levels of CCTbeta protein and the major client protein Gbeta1 that were significantly reduced in the homozygous cct2-L394H-7del mutant compared with wild-type. These results indicate that cct2 plays an essential role in retinal development by regulating the cell cycle. Conclusions: The retinal pathology observed in the homozygous cct2-L394H-7del mutants resembles the retinal pathology of human LCA patients. PMID- 29450545 TI - Use of the Posterior/Anterior Corneal Curvature Radii Ratio to Improve the Accuracy of Intraocular Lens Power Calculation: Eom's Adjustment Method. AB - Purpose: To evaluate the accuracy of IOL power calculation using adjusted corneal power according to the posterior/anterior corneal curvature radii ratio. Methods: Nine hundred twenty-eight eyes from 928 reference subjects and 158 eyes from 158 cataract patients who underwent phacoemulsification surgery were enrolled. Adjusted corneal power of cataract patients was calculated using the fictitious refractive index that was obtained from the geometric mean posterior/anterior corneal curvature radii ratio of reference subjects and adjusted anterior and predicted posterior corneal curvature radii from conventional keratometry (K) using the posterior/anterior corneal curvature radii ratio. The median absolute error (MedAE) based on the adjusted corneal power was compared with that based on conventional K in the Haigis and SRK/T formulae. Results: The geometric mean posterior/anterior corneal curvature radii ratio was 0.808, and the fictitious refractive index of the cornea for a single Scheimpflug camera was 1.3275. The mean difference between adjusted corneal power and conventional K was 0.05 diopter (D). The MedAE based on adjusted corneal power (0.31 D in the Haigis formula and 0.32 D in the SRK/T formula) was significantly smaller than that based on conventional K (0.41 D and 0.40 D, respectively; P < 0.001 and P < 0.001, respectively). The percentage of eyes with refractive prediction error within +/- 0.50 D calculated using adjusted corneal power (74.7%) was significantly greater than that obtained using conventional K (62.7%) in the Haigis formula (P = 0.029). Conclusions: IOL power calculation using adjusted corneal power according to the posterior/anterior corneal curvature radii ratio provided more accurate refractive outcomes than calculation using conventional K. PMID- 29450544 TI - HLA Class I Antigen Expression in Conjunctival Melanoma Is Not Associated With PD L1/PD-1 Status. AB - Purpose: Antitumor T cells need expression of HLA class I molecules but can be inhibited by ligands such as programmed death ligand 1 (PD-L1). We determined expression and regulation of these molecules in human conjunctival melanoma (CM) samples, cell lines, and murine xenografts. Methods: Immunofluorescence staining was performed to examine the expression of HLA-A, HLA-B/C, and beta-2 microglobulin (B2M) in 23 primary CM samples. HLA class I expression was compared with clinicopathologic characteristics, the presence of tumor-infiltrating leukocytes, and PD-L1/PD-1 status. The effect of interferon gamma (IFN-gamma) on HLA class I expression was tested on three CM cell lines using quantitative PCR and flow cytometry. Furthermore, HLA class I expression was determined in CM cell line-derived murine xenografts. Results: One third of tumors had positive HLA-A, HLA-B/C, and B2M expression. A positive expression was especially seen in thin and epibulbar tumors but was not associated with recurrences. HLA class I expression was correlated with M2 macrophage density and tended to associate with CD8+ T-cell density but was independent of PD-L1 or PD-1 expression. IFN-gamma upregulated HLA class I expression and genes involved in HLA transcription and transportation on CM cell lines. Murine xenografts showed a comparable HLA class I expression as their respective cell lines. Conclusions: Our data indicate that subsets of CM have positive HLA class I expression, and HLA class I and PD-L1/PD 1 are expressed independently. When one considers immunotherapy, one should also analyze HLA class I expression, whose downregulation can limit the efficacy of T cell-mediated therapies.

AB - Purpose: To determine the plasma metabolomic signature of the exfoliative syndrome (XFS), the most common cause worldwide of secondary open-angle glaucoma. Methods: We performed a targeted metabolomic study, using the standardized p180 Biocrates Absolute IDQ p180 kit with a QTRAP 5500 mass spectrometer, to compare the metabolomic profiles of plasma from individuals with XFS (n = 16), and an age and sex-matched control group with cataract (n = 18). Results: A total of 151 metabolites were detected correctly, 16 of which allowed for construction of an OPLS-DA model with a good predictive capability (Q2cum = 0.51) associated with a low risk of over-fitting (permQ2 = -0.48, CV-ANOVA P-value <0.001). The metabolites contributing the most to the signature were octanoyl-carnitine (C8) and decanoyl-carnitine (C10), the branched-chain amino acids (i.e., isoleucine, leucine, and valine), and tyrosine, all of which were at higher concentrations in the XFS group, whereas spermine and spermidine, together with their precursor acetyl-ornithine, were at lower concentrations than in the control group. Conclusions: We identified a significant metabolomic signature in the plasma of individuals with XFS. Paradoxically, this signature, characterized by lower concentrations of the neuroprotective spermine and spermidine polyamines than in controls, partially overlaps the plasma metabolomic profile associated with insulin resistance, despite the absence of evidence of insulin resistance in XFS. PMID- 29450547 TI - Aflibercept Action in a Rabbit Model of Chronic Retinal Neovascularization: Reversible Inhibition of Pathologic Leakage With Dose-Dependent Duration. AB - Purpose: We establish and characterize the chronic retinal neovascularization (RNV) induced by intravitreal (IVT) injection of DL-alpha-aminoadipic acid (AAA) in a rabbit model and investigate the extent and duration of inhibitory actions induced by IVT aflibercept on the RNV. Methods: Rabbits received a single IVT injection of AAA, with weekly follow-up fundus photography, fluorescein angiography (FA), and optical coherence tomography (OCT). After 10 weeks, they received a single IVT aflibercept or control injection. RNV leakage was quantified from FA by image analysis with Photoshop. Some eyes were collected for histologic analysis. Results: IVT AAA produced neuronal degeneration over a large fraction of the retina. RNV formed in the damaged area and by 10 weeks exhibited stable morphology and leakage, which persisted for at least 65 weeks. Control IVT injections did not affect RNV leakage, but IVT aflibercept completely blocked RNV leakage. The inhibition was reversible (i.e., the leakage returned as the drug cleared), and the duration of antileak effects with 500 MUg aflibercept was approximately 8 weeks. Partial regression of the pathologic vasculature also occurred with aflibercept, with reestablishment as the drug cleared. Conclusions: This model mimics a chronic human disease in its stability and persistence, and the antileak action of aflibercept is fully reversible with a dose-dependent duration. Therefore, this large eye model is uniquely suitable for investigations into the efficacy and duration of action of novel formulations and pharmacotherapies for retinal vascular diseases, and for studying the underlying pathobiology of retinal angiogenesis.

AB - The 12-lead surface electrocardiogram (ECG) is of great importance for the diagnostics of cardiac arrhythmias. For the correct and systematic analysis it has a sensitivity and specificity for the correct diagnosis of supraventricular tachycardia or ventricular tachycardia of more than 95%. Nevertheless, the assessment of cardiac rhythm disorders is difficult for many physicians. In this way errors can occur, frequently due to a non-systematic analysis of the ECG; therefore, the aim of this article is to present the techniques and the necessary knowledge for assessment of the most frequent bradycardiac and tachycardiac heart rhythm disorders. Additionally, special features in the analysis of the ECG results in children are discussed. PMID- 29450561 TI - Cognitive performance of patients with chronic heart failure on sacubitril/valsartan : A retrospective cohort study. AB - BACKGROUND: Sacubitril, a neprilysin inhibitor in the combination molecule sacubitril/valsartan, slows down degradation of endogenous natriuretic peptides, thereby enhancing their beneficial cardiovascular effects. However, sacubitril might also promote neuronal dysfunction and cognitive impairment in patients with chronic heart failure (CHF) treated with sacubitril/valsartan, due to possible neprilysin inhibition at the level of Central Nervous System. METHODS: A retrospective cohort study was undertaken to detect the effects exerted by sacubitril/valsartan on cognitive function in CHF patients. The patients' clinical data were examined for information provided in the Mini-Mental State Examination (MMSE), which was routinely administered during clinical visits at two centers from 15 March to 31 October 2017. Patients in the sacubitril/valsartan group had a clinical history of at least 3 months of continuous sacubitril/valsartan administration. The control group comprised CHF patients on conventional therapy not taking sacubitril/valsartan. In the between group comparison, patients were matched for mean age, educational level, sex, NYHA class, and comorbidities. In the present retrospective study only patients in NYHA class II-III were enrolled. RESULTS: The mean MMSE score was 22.72 +/- 2.68 (mean +/- standard deviation [SD]) in the sacubitril/valsartan group (n = 51 patients) vs. 21.96 +/- 2.73 (mean +/- SD) in the control group (n = 51; p = 0.1572, independent samples t-test). Thus, a similar mild-to-moderate impairment in cognitive performance was found in the comparison between the two groups. CONCLUSION: In our study, we did not find any evidence of the alleged harmful influence of sacubitril/valsartan on cognitive function. Patients taking sacubitril/valsartan for at least 3 months had similar mean MMSE scores to control subjects. PMID- 29450562 TI - [Which typical foot fractures should the radiologist know?] AB - CLINICAL/METHODICAL ISSUE: Due to mechanical loading and the number of joints involved, fractures of the foot are among the most common fractures. STANDARD RADIOLOGICAL METHODS: X-ray is basis for diagnostic workup of all foot fractures. METHODICAL INNOVATIONS: For stress fractures, the additional use of magnetic resonance imaging (MRI) is indicated. Computed tomography (CT) can be used for preoperative imaging of intraarticular tarsal fractures. PERFORMANCE: Simple traumatic fractures can be reliably diagnosed by X-ray. On the other hand, there is a poor sensitivity for stress fractures. ACHIEVEMENTS: Using a combination of X-ray, MRI, and CT, it is possible to reliably diagnosis and classify foot fractures. PRACTICAL RECOMMENDATIONS: The first step to diagnose a foot fracture should be the X-ray. CT and MRI can also be used to detect intra-articular fractures and MRI can be used for stress fractures.

PMID- 29450565 TI - Tissue distribution of gold and silver after subacute intravenous injection of co administered gold and silver nanoparticles of similar sizes. AB - Gold (AuNPs, 12.8 nm) and silver nanoparticles (AgNPs, 10 nm), mixed or separate, were injected into the caudal vein of male Sprague-Dawley rats for 4 weeks. The rats were allowed to recover for further 4 weeks to examine the differences in AuNP/AgNP tissue distribution and clearance. The size distribution of injected AuNPs and AgNPs were not statistically different. The dose groups (five males per group for the administration and three males for the recovery) consisted of seven divisions, i.e., control, AgNPs (with a low dose of 10 ug/kg/day, and, a high dose of 100 ug/kg/day), AuNPs (with a low dose of 10 ug/kg/day, and, a high dose of 100 ug/kg/day), as well as mixed AgNPs/AuNPs (with a low dose of 10/10 ug/kg/day, and a high dose of 100/100 ug/kg/day). The AgNPs accumulated in a dose dependent manner in the liver, spleen, kidneys, lung, brain, testis or blood. Au concentration increased also in a dose-dependent manner in the liver, kidneys, spleen and lungs, but not in the brain, testis and blood. Ag concentration in the tissues increased dose-dependently after 4 weeks of AgNP/AuNP mixed administration, but to a much lower extent than those observed when they were administered separately. Ag concentration in the tissues after 4 weeks of AgNP/AuNP mixed administration cleared dose-dependently after 4 weeks of recovery. Au concentration in the tissues increased dose-dependently after 4 weeks of AgNp/AuNP mixed administration, while Au concentration in the tissues did not clear as seen in Ag after 4 weeks recovery. Au concentration showed biopersistency or accumulation in the liver, kidneys, spleen and brain of the 4 weeks of recovery. In conclusion, AgNPs and AuNPs showed different toxicokinetic properties and the mixed administration of AgNPs with AuNPs resulted in mutual reduction of their tissue distribution which appeared to be due to competitive inhibition. Furthermore, this subacute intravenous injection study has suggested that these nanoparticles were distributed to the organs in particulate instead of ionic forms. PMID- 29450566 TI - Unicompartmental knee arthroplasty fails to completely restore normal gait patterns during level walking. AB - PURPOSE: Gait analysis is a valuable instrument for measuring function objectively after unicompartmental knee arthroplasty (UKA). However, most gait analysis studies have reported conflicting results for functional assessment after UKA. This meta-analysis compared the gait patterns of UKA patients and healthy controls during level walking. METHODS: Studies were included in the meta analysis if they recorded vertical ground reaction force (GRF), flexion at initial contact, flexion at loading response, extension at mid-stance, flexion at swing, walking speed, cadence, and stride length in UKA patients or healthy controls. RESULTS: Seven studies met the criteria for inclusion in the meta analysis. The UKA patients and healthy controls were similar in terms of vertical GRF (95% CI - 0.54 to 0.23; ns), flexion at initial contact (95% CI - 0.47 to 4.96; ns), flexion at loading response (95% CI - 1.29 to 3.69; ns), and flexion at swing (95% CI - 8.85 to 0.40; ns). In contrast, extension at mid-stance (95% CI 0.53 to 4.88; P = 0.01), walking speed (95% CI - 2.13 to - 0.15; P = 0.02), cadence (95% CI - 1.02 to - 0.25; P = 0.001), and stride length (95% CI - 2.02 to - 0.22; P = 0.01) differed significantly between groups. Subgroup analyses revealed that the pooled data were similar between groups: 1st maximum (heel strike), - 0.43 BW (ns); 1st minimum (mid-stance), 0.61 BW (ns); and 2nd maximum (toe off), - 0.46 BW (ns). CONCLUSIONS: There were no significant differences in vertical GRF or overall kinematics in the sagittal plane between UKA patients and healthy controls during level walking. However, the UKA group had a significantly slower walking speed and cadence and a shorter stride length than healthy controls. The current findings suggest that, clinically, UKA fails to completely restore normal gait patterns. LEVEL OF EVIDENCE: Level II, therapeutic study. PMID- 29450567 TI - Coronal tibial anteromedial tunnel location has minimal effect on knee biomechanics. AB - PURPOSE: Studies have found anatomic variation in the coronal position of the insertion site of anteromedial (AM) bundle of the anterior cruciate ligament (ACL) on the tibia, which can lead to questions about tunnel placement during ACL reconstruction. The purpose of this study was to determine how mediolateral placement of the tibial AM graft tunnel in double-bundle ACL reconstructions affects knee biomechanics. METHODS: Two different types of double-bundle ACL reconstructions were performed. The AM tibial tunnel was placed at either the medial or lateral portion of tibial AM footprint. Nine cadaveric knees were tested with the robotic/universal force-moment sensor system with the use of (1) an 89.0-N anterior tibial load at full extension (FE), 30 degrees , 60 degrees and 90 degrees of knee flexion and (2) a combined 7.0-Nm valgus torque and 5.0 Nm internal tibial rotation torque at FE, 15 degrees , 30 degrees and 45 degrees of knee flexion. RESULTS: Both medial (2.6 +/- 1.2 mm) and lateral (1.6 +/- 0.9 mm) double-bundle reconstructions reduced the anterior tibial translation (ATT) to less than the intact value (3.9 +/- 0.7 mm) at FE. At all other flexion angles, there was no significant different in ATT between the intact knee and the reconstructions. At FE, the ATT for the medial AM reconstruction was different from that of the lateral AM construction and closer to the intact ACL value. CONCLUSION: The coronal tibial placement of the AM tunnel had only a slight effect on knee biomechanics. In patients with differing AM bundle coronal positions, the AM tibial tunnel can be placed anatomically at the native insertion site.

AB - Bird feathers have been proven to be reliable indicators of metal exposure originating from contaminated food and polluted environments. The concentrations of 15 essential and non-essential metals were investigated in African penguins (Spheniscus demersus) feathers from a Northwestern Italian zoological facility. These birds are exclusively fed with herring from the northeast Atlantic Ocean. Certain elements, such as Hg and Cd, reflected the bioaccumulation phenomena that occur through the marine food chain. The levels of Cr, Mn, and Ni were comparable to those registered in feathers of birds living in polluted areas. These results are important for comparative studies regarding the health, nutrition and welfare of endangered seabirds kept under human care. PMID- 29450569 TI - Pharmacogenomics in diabetes: outcomes of thiamine therapy in TRMA syndrome. AB - AIMS/HYPOTHESIS: Diabetes is one of the cardinal features of thiamine-responsive megaloblastic anaemia (TRMA) syndrome. Current knowledge of this rare monogenic diabetes subtype is limited. We investigated the genotype, phenotype and response to thiamine (vitamin B1) in a cohort of individuals with TRMA-related diabetes. METHODS: We studied 32 individuals with biallelic SLC19A2 mutations identified by Sanger or next generation sequencing. Clinical details were collected through a follow-up questionnaire. RESULTS: We identified 24 different mutations, of which nine are novel. The onset of the first TRMA symptom ranged from birth to 4 years (median 6 months [interquartile range, IQR 3-24]) and median age at diabetes onset was 10 months (IQR 5-27). At presentation, three individuals had isolated diabetes and 12 had asymptomatic hyperglycaemia. Follow-up data was available for 15 individuals treated with thiamine for a median 4.7 years (IQR 3-10). Four patients were able to stop insulin and seven achieved better glycaemic control on lower insulin doses. These 11 patients were significantly younger at diabetes diagnosis (p = 0.042), at genetic testing (p = 0.01) and when starting thiamine (p = 0.007) compared with the rest of the cohort. All patients treated with thiamine became transfusion-independent and adolescents achieved normal puberty. There were no additional benefits of thiamine doses >150 mg/day and no reported side effects up to 300 mg/day. CONCLUSIONS/INTERPRETATION: In TRMA syndrome, diabetes can be asymptomatic and present before the appearance of other features. Prompt recognition is essential as early treatment with thiamine can result in improved glycaemic control, with some individuals becoming insulin-independent.

AB - Health status of freshwater fish, Cirrhina mrigala was studied by qualitative and quantitative histopathological analysis, alterations in frequency/prevalence percentages (%) and histological alteration indices (HAI) in response to metal contaminated sediments of the River Ravi aquatic ecosystem. Histo-structures of gill and liver samples of fish were analyzed and comparison between the degree of damage of the alterations in fish organs was performed after exposure to metal contaminated sediments for 7, 14 and 28 days under semi-static water renewal bioassays. Histopathological studies revealed marked histological alterations in the gills and liver of exposed fish as compared to normal tissue structure observed in control fish. The frequency and prevalence percentages observed in 28 day exposed fish were significantly higher as compared to 7- and 14-day exposed fish. The order of frequency and prevalence percentage for gills and liver of exposed fish was as: 28-day > 14-day > 7-day. The highest prevalence percentages recorded were 83 and 80% as focal area of necrosis in gill and liver, respectively, after 28-day exposure. The lowest prevalence percentage observed in 7-day exposed Cirrhina mrigala was dilation of sinusoids (17%). PMID- 29450572 TI - Plant Genetics and Molecular Biology: An Introduction.

AB - PURPOSE: CD38 is considered a potential biomarker for multiple myeloma (MM) and has shown a strong link with chronic lymphocytic leukemia due to high and uniform expression on plasma cells. In vivo evaluation of CD38 expression may provide useful information about lesion detection and prognosis of treatment in MM. In this study, immunoPET imaging with 89Zr-labeled daratumumab was used for differentiation of CD38 expression in murine lymphoma models to provide a potential non-invasive method for monitoring CD38 in the clinic. METHODS: Daratumumab was radiolabeled with 89Zr (t1/2 = 78.4 h) via conjugation with desferrioxamine (Df). After Western blot (WB) was used to screen CD38 expression in five lymphoma cell lines, flow cytometry and cellular binding assays were performed to test the binding ability of labeled or conjugated daratumumab with CD38 in vitro. PET imaging and biodistribution studies were performed to evaluate CD38 expression after injection of 89Zr-Df-daratumumab. 89Zr-Df-IgG was also evaluated as a non-specific control group in the Ramos model. Finally, CD38 expression in tumor tissues was verified by histological analysis. RESULTS: Using WB screening, the Ramos cell line was found to express the highest level of CD38 while the HBL-1 cell line had the lowest expression. Df-conjugated and 89Zr labeled daratumumab displayed similar high binding affinities with Ramos cells. PET imaging of 89Zr-Df-daratumumab showed a high tumor uptake of up to 26.6 +/- 8.0 %ID/g for Ramos at 120 h post-injection, and only up to 6.6 +/- 2.9 %ID/g for HBL-1 (n = 4). Additionally, 89Zr-Df-IgG demonstrated a low tumor uptake in the Ramos model (only 4.3 +/- 0.8 %ID/g at 120 h post-injection). Ex vivo biodistribution studies showed similar trends with imaging results. Immunofluorescence staining of tumor tissues verified higher CD38 expression of Ramos than that of HBL-1. CONCLUSIONS: The role of 89Zr-Df-daratumumab was investigated for evaluating CD38 expression in lymphoma models non-invasively and was found to be to a promising imaging agent of CD38-positive hematological diseases such as MM in future clinical applications. PMID- 29450584 TI - Dietary patterns and longitudinal change in hip bone mineral density among older men. AB - : Studying dietary patterns is often more informative than individual nutrients or foods. We found that a Prudent dietary pattern (rich in vegetables and fish) was associated with reduced loss of total hip BMD in older men. A Prudent dietary pattern may be a potential lifestyle strategy for minimizing bone loss. INTRODUCTION: This study aimed to identify baseline dietary patterns using factor analysis in a cohort of older men and to evaluate whether the dietary patterns were associated with bone mineral density change (%DeltaBMD) at the total hip and femoral neck over time. METHODS: Participants (n = 4379; mean age 72.9 +/- 5.5 years) were from the Osteoporotic Fractures in Men (MrOS) prospective cohort study and had dietary data collected at baseline (March 2000-April 2002) and BMD measured at baseline and Visit 2 (March 2005-May 2006). Dietary intake was assessed with a brief Block food frequency questionnaire (FFQ); factor analysis was used to derive dietary patterns. BMD was measured by dual-energy x-ray absorptiometry (DXA); %DeltaBMD was calculated from baseline to Visit 2. We used generalized linear regression to estimate least square (LS) means of %DeltaBMD in quartiles of the dietary pattern scores adjusted for potential confounding factors. RESULTS: Two major dietary patterns were derived: Prudent (abundant in vegetables, salad, and non-fried fish) and Western (rich in hamburger, fries, processed meats, cheese, and sweets/desserts). There was an inverse association between adherence to the Prudent pattern and total hip %DeltaBMD (p-trend = 0.028 after adjusting for age and clinical site; p-trend = 0.033 after further adjustment for smoking, calcium supplement use, diabetes, hypertension, and total energy intake). No other consistent associations between dietary patterns and %DeltaBMD were observed. CONCLUSIONS: Greater adherence to a Prudent dietary pattern may attenuate total hip BMD loss (%DeltaBMD) in older men. PMID- 29450585 TI - Effect of isolated vitamin D supplementation on bone turnover markers in younger postmenopausal women: a randomized, double-blind, placebo-controlled trial. AB - : Vitamin D (VD) plays an important role in bone mineralization. The present study investigates the effect of VD supplementation alone on bone turnover markers in younger postmenopausal women. It has been shown that VD supplementation in postmenopausal women with hypovitaminosis D is associated with a reduction in bone turnover markers. PURPOSE: The purpose of this study is to evaluate the effect of VD supplementation alone on bone turnover markers in younger postmenopausal women. METHODS: In this double-blind, placebo-controlled trial, 160 women were randomized into the VD group (supplementation with 1000 IU of vitamin D3/day, orally; n = 80) or placebo group (n = 80). Women aged 50-65 years with amenorrhea >= 12 months and normal bone mineral density were included. The intervention lasted 9 months, and the participants were assessed at the beginning and end of treatment. Serum levels of total calcium, parathormone (PTH), alkaline phosphatase (AP), and 24-h urine calcium were determined. Serum C terminal telopeptide of type I collagen (s-CTX) and procollagen type 1 N-terminal propeptide (P1NP) were measured by immunoassay as markers of bone resorption and formation, respectively. Plasma 25-hydroxyvitamin-D [25(OH)D] concentrations were measured by HPLC. Intention-to-treat analysis was performed using ANOVA, Student's t test, Tukey's test, and gamma distribution. RESULTS: Over the period of 9 months, 25(OH)D concentrations increased from 15.0 +/- 7.5 to 27.5 +/- 10.4 ng/mL (+ 45.4%) in the VD group and decreased from 16.9 +/- 6.7 to 13.8 +/- 6.0 ng/mL (- 18.5%) in the placebo group (p < 0.001). There was a decrease (- 21.3%) of PTH levels in the VD group with a significant difference between groups at the end of the study (p < 0.001). No significant differences were observed in the other laboratory parameters (total calcium, AP, and calciuria) in either group (p > 0.05). A comparison of bone turnover markers showed a significant reduction in of s-CTX (- 24.2%, p < .0001) and P1NP (- 13.4%, p = 0.003) levels in the VD group. No significant variations in bone turnover markers were observed in the placebo group (s-CTX, - 6.9%, p = 0.092 and P1NP, - 0.6%, p = 0.918). CONCLUSION: In younger postmenopausal women with VD deficiency, isolated supplementation with 1000 IU of vitamin D3 for 9 months is associated with a reduction in bone turnover markers. However, any between-group differences was not observed in bone turnover markers. PMID- 29450587 TI - Morphogenetic Alterations in Melipona quadrifasciata anthidioides (Hymenoptera: Apidae) Associated with Pesticides. AB - Bees are major pollinators of both native flora and cultured crops. Nonetheless, despite their key functional role in ecosystems and agriculture, bee populations have been affected worldwide by deforestation and contamination by insecticides. Conversely, little is known about the effects of pesticides on morphogenetic development of neotropical stingless bees. We compared the fluctuating asymmetry (FA) in newly emerged bees and foragers of Melipona quadrifasciata anthidioides exposed to pesticides (experimental greenhouse and cultivated field). In addition, visitation behavior of foragers was inferred from pollen analyses and direct observation. A significant increase of FA (P < 0.001) was detected in bees from the greenhouse. Even though pesticides might affect their development, foragers seem to avoid contaminated plants whenever possible, as confirmed by pollen and visitation analyses. Consequently, the conservation of natural forests in agricultural landscapes is essential to ensure the health of colonies in stingless bees. PMID- 29450586 TI - The host control of a clinical isolate strain of P. aeruginosa infection is independent of Nod-1 but depends on MyD88. AB - OBJECTIVE AND DESIGN: The objective of this study was to investigate the role of Nod1 in the recruitment of neutrophils into the infection site and in the establishment of the inflammatory response elicited by a clinical isolate strain of P. aeruginosa in vivo, while comparing it to the well-established role of MyD88 in this process. SUBJECTS: Wild-type, Nod1-/- and MyD88-/- mice, all with a C57Bl/6 background. METHODS: Mice were intranasally infected with Pseudomonas aeruginosa DZ605. Bronchoalveolar lavage and blood were harvested 6 or 20 h post infection for evaluating bacterial load, chemokine levels and neutrophil migration. Survival post-infection was also observed. RESULTS: We show here that wild-type and Nod1-/- mice induce similar lung chemokine levels, neutrophil recruitment, and bacterial load, thus leading to equal survival rates upon P. aeruginosa pulmonary infection. Furthermore, we confirmed the essential role of MyD88-dependent signalling in recruiting neutrophils and controlling P. aeruginosa-induced pulmonary infection. CONCLUSION: The results suggest that in contrast to MyD88, under our experimental conditions, the absence of Nod1 does not impair the recruitment of neutrophils in response to P. aeruginosa DZ605. PMID- 29450588 TI - Response rates and recurrence patterns after low-dose radiotherapy with 4 Gy in patients with low-grade lymphomas. AB - PURPOSE: Retrospective study of effectiveness, toxicity, and relapse patterns after low-dose radiotherapy (LDRT) in patients with low-grade lymphomas. METHODS: 47 patients (median age 64 years) with 50 lesions were treated with LDRT (2 * 2 Gy). In 60%, LDRT was the primary and curative treatment, in 40% offered as second-line therapy in recurrent disease. Histology included follicular (57%) and marginal zone lymphomas (43%). Patients were followed-up regularly clinically (skin) and with CT or MRI scans. RESULTS: Median follow-up was 21 months. 84% of the lesions were extranodal disease (32% orbit, 14% salivary glands, 30% skin, and 8% others). Most lesions were <=5 cm (90%) with a singular affection (74%). 26% of the patients received rituximab simultaneously. Overall response rate (ORR) was 90% (all lesions), 93.3% (primary treatment), and 85% (recurrence treatment); p = 0.341. 2-year Local progression-free survival (LPFS) for all, curative, and palliative patients was 91.1%, 96.7%, and 83.8%, respectively; p = 0.522. Five relapses were detected: three infield only, and were therefore treated with LDRT or subsequent local RT of 30 Gy. Two patients showed an in- and outfield progression and were consequently treated with chemotherapy. Predictive factors for higher LPFS were tumor size <=5 cm (p = 0.003), <=2 previous treatments (p = 0.027), no skin involvement (p = 0.05), singular affection (p = 0.075), and simultaneous rituximab application (p = 0.148). LDRT was tolerated well, without detectable acute or long-term side effects. CONCLUSION: Primary LDRT is an effective treatment with high ORR and long-lasting remissions in a subset of patients with low-grade lymphoma, and may therefore be a curative treatment option for patients with low tumor burden. LDRT with the CD20 antibody obinutuzumab will soon be tested in a prospective multicenter trial. PMID- 29450589 TI - Effect of continuous positive airway pressure administration during lung stereotactic ablative radiotherapy: a comparative planning study. AB - PURPOSE: By increasing lung volume and decreasing respiration-induced tumour motion amplitude, administration of continuous positive airway pressure (CPAP) during stereotactic ablative radiotherapy (SABR) could allow for better sparing of the lungs and heart. In this study, we evaluated the effect of CPAP on lung volume, tumour motion amplitude and baseline shift, as well as the dosimetric impact of the strategy. METHODS: Twenty patients with lung tumours referred for SABR underwent 4D-computed tomography (CT) scans with and without CPAP (CPAP/noCPAP) at two timepoints (T0/T1). First, CPAP and noCPAP scans were compared for lung volume, tumour motion amplitude, and baseline shift. Next, CPAP and noCPAP treatment plans were computed and compared for lung dose parameters (mean lung dose (MLD), lung volume receiving 20 Gy (V20Gy), 13 Gy (V13Gy), and 5 Gy (V5Gy)) and mean heart dose (MHD). RESULTS: On average, CPAP increased lung volume by 8.0% (p < 0.001) and 6.3% (p < 0.001) at T0 and T1, respectively, but did not change tumour motion amplitude or baseline shift. As a result, CPAP administration led to an absolute decrease in MLD, lung V20Gy, V13Gy and V5Gy of 0.1 Gy (p = 0.1), 0.4% (p = 0.03), 0.5% (p = 0.04) and 0.5% (p = 0.2), respectively, while having no significant influence on MHD. CONCLUSIONS: In patients referred for SABR for lung tumours, CPAP increased lung volume without modifying tumour motion or baseline shift. As a result, CPAP allowed for a slight decrease in radiation dose to the lungs, which is unlikely to be clinically significant. PMID- 29450591 TI - Occurrence of pneumonitis following radiotherapy of breast cancer - A prospective study. AB - AIM: of this study is to determine the temporal resolution of therapy-induced pneumonitis, and to assess promoting factors in adjuvant treated patients with unilateral mammacarcinoma. PATIENTS AND METHODS: A total of 100 post-surgery patients were recruited. The cohort was treated by 2 field radiotherapy (2FRT; breast and chest wall, N = 75), 3 field radiotherapy (3FRT; + supraclavicular lymphatic region, N = 8), or with 4 field radiotherapy (4FRT; + parasternal lymphatic region, N = 17). Ninety-one patients received various systemic treatments prior to irradiation. Following an initial screening visit post-RT, two additional visits after 12 and 25 weeks were conducted including radiographic examination. In addition, general anamnesis and the co-medication were recorded. The endpoint was reached as soon as a pneumonitis was developed or at maximum of six months post-treatment. RESULTS: A pneumonitis incidence of 13% was determined. Of 91 patients with prior systemic therapy, 11 patients developed pneumonitis. Smoking history and chronic obstructive pulmonary disease (COPD) appeared to be positive predictors, whereas past pneumonia clearly promoted pneumonitis. Further pneumonitis-promoting predictors are represented by the applied field extensions (2 field radiotherapy [2FRT] < 3 field radiotherapy [3FRT] < 4 field radiotherapy [4FRT]) and the type of combined initial systemic therapies. As a consequence, all of the three patients in the study cohort treated with 4FRT and initial chemotherapy combined with anti-hormone and antibody protocols developed pneumonitis. A combination of the hormone antagonists tamoxifen and goserelin might enhance the risk for pneumonitis. Remarkably, none of the 11 patients co-medicated with statins suffered from pneumonitis. CONCLUSIONS: The rapidly increasing use of novel systemic therapy schedules combined with radiotherapy (RT) needs more prospective studies with larger cohorts. Our results indicate that contribution to pneumonitis occurrence of various (neo)adjuvant therapy approaches followed by RT is of minor relevance, whereas mean total lung doses of >10 Gy escalate the risk of lung tissue complications. The validity of potential inhibitors of therapy-induced pneumonitis as observed for statin co-medication should further be investigated in future trials. PMID- 29450592 TI - Under-reported dosimetry errors due to interplay effects during VMAT dose delivery in extreme hypofractionated stereotactic radiotherapy. AB - BACKGROUND AND PURPOSE: Radiotherapy of extracranial metastases changed from normofractioned 3D CRT to extreme hypofractionated stereotactic treatment using VMAT beam techniques. Random interaction between tumour motion and dynamically changing beam parameters might result in underdosage of the CTV even for an appropriately dimensioned ITV (interplay effect). This study presents a clinical scenario of extreme hypofractionated stereotactic treatment and analyses the impact of interplay effects on CTV dose coverage. METHODS: For a thoracic/abdominal phantom with an integrated high-resolution detector array placed on a 4D motion platform, dual-arc treatment plans with homogenous target coverage were created using a common VMAT technique and delivered in a single fraction. CTV underdosage through interplay effects was investigated by comparing dose measurements with and without tumour motion during plan delivery. RESULTS: Our study agrees with previous works that pointed out insignificant interplay effects on target coverage for very regular tumour motion patterns like simple sinusoidal motion. However, we identified and illustrated scenarios that are likely to result in a clinically relevant CTV underdosage. For tumour motion with abnormal variability, target coverage quantified by the CTV area receiving more than 98% of the prescribed dose decreased to 78% compared to 100% at static dose measurement. CONCLUSION: This study is further proof of considerable influence of interplay effects on VMAT dose delivery in stereotactic radiotherapy. For selected conditions of an exemplary scenario, interplay effects and related motion-induced target underdosage primarily occurred in tumour motion pattern with increased motion variability and VMAT plan delivery using complex MLC dose modulation.

PMID- 29450594 TI - Position paper for the organization of ECMO programs for cardiac failure in adults. AB - Extracorporeal membrane oxygenation (ECMO) has been used increasingly for both respiratory and cardiac failure in adult patients. Indications for ECMO use in cardiac failure include severe refractory cardiogenic shock, refractory ventricular arrhythmia, active cardiopulmonary resuscitation for cardiac arrest, and acute or decompensated right heart failure. Evidence is emerging to guide the use of this therapy for some of these indications, but there remains a need for additional evidence to guide best practices. As a result, the use of ECMO may vary widely across centers. The purpose of this document is to highlight key aspects of care delivery, with the goal of codifying the current use of this rapidly growing technology. A major challenge in this field is the need to emergently deploy ECMO for cardiac failure, often with limited time to assess the appropriateness of patients for the intervention. For this reason, we advocate for a multidisciplinary team of experts to guide institutional use of this therapy and the care of patients receiving it. Rigorous patient selection and careful attention to potential complications are key factors in optimizing patient outcomes. Seamless patient transport and clearly defined pathways for transition of care to centers capable of providing heart replacement therapies (e.g., durable ventricular assist device or heart transplantation) are essential to providing the highest level of care for those patients stabilized by ECMO but unable to be weaned from the device. Ultimately, concentration of the most complex care at high-volume centers with advanced cardiac capabilities may be a way to significantly improve the care of this patient population. PMID- 29450596 TI - [Strategies for a regenerative therapy of hearing loss. German version]. AB - Despite impressive technical progress in the field of conventional hearing aids and implantable hearing systems, the hopes for the treatment of inner ear diseases such as hearing loss and tinnitus have become increasingly directed toward regenerative therapeutic approaches. This review discusses the currently most promising strategies for hair cell regeneration in the inner ear to treat hearing loss, including stem cell-based, gene transfer-based, and pharmacological interventions. Furthermore, previous milestones and ground-breaking work in this scientific field are identified. After many years of basic research, the first clinical trials with a regenerative therapeutic approach for hearing-impaired patients were recently initiated. Although there is still a long and bumpy road ahead until a true breakthrough is achieved, it seems more realistic than ever that regenerative therapies for the inner ear will find their way into clinical practice. PMID- 29450597 TI - Unenhanced 320-row multidetector computed tomography of the brain in children: comparison of image quality and radiation dose among wide-volume, one-shot volume, and helical scan modes. AB - BACKGROUND: The 320-row multidetector computed tomography (CT) scanner has multiple scan modes, including volumetric modes. OBJECTIVE: To compare the image quality and radiation dose of 320-row CT in three acquisition modes - helical, one-shot volume, and wide-volume scan - at pediatric brain imaging. MATERIALS AND METHODS: Fifty-seven children underwent unenhanced brain CT using one of three scan modes (helical scan, n=21; one-shot volume scan, n=17; wide-volume scan, n=19). For qualitative analysis, two reviewers evaluated overall image quality and image noise using a 5-point grading system. For quantitative analysis, signal to-noise ratio, image noise and posterior fossa artifact index were calculated. To measure the radiation dose, adjusted CT dose index per unit volume (CTDIadj) and dose length product (DLP) were compared. RESULTS: Qualitatively, the wide volume scan showed significantly less image noise than the helical scan (P=0.009), and less streak artifact than the one-shot volume scan (P=0.001). The helical mode showed significantly lower signal-to-noise ratio, with a higher image noise level compared with the one-shot volume and wide-volume modes (all P<0.05). The CTDIadj and DLP were significantly lower in the one-shot volume and wide-volume modes compared with those in the helical scan mode (all P<0.05). CONCLUSION: For pediatric unenhanced brain CT, both the wide-volume and one-shot volume scans reduced radiation dose compared to the helical scan mode, while the wide-volume scan mode showed fewer streak artifacts in the skull vertex and posterior fossa than the one-shot volume scan.

AB - PURPOSE: The Public Mental Health Care (PMHC) system is a network of public services and care- and support institutions financed from public funds. Performance indicators based on the registration of police contacts could be a reliable and useful source of information for the stakeholders of the PMHC system to monitor performance. This study aimed to provide evidence on the validity of using police contacts as a performance indicator to assess the continuity of care in the PMHC system. METHODS: Data on services received, police contacts and detention periods of 1928 people that entered the PMHC system in the city of Amsterdam were collected over a period of 51 months. Continuity of care was defined as receiving more than 90 days of uninterrupted service. The associations between police contacts and continuity were analyzed with multilevel Poisson and multivariate linear regression modeling. RESULTS: Clients had on average 2.12 police contacts per person-year. Clients with police contacts were younger, more often single, male, and more often diagnosed with psychiatric or substance abuse disorders than clients without police contacts. Incidence rates of police contacts were significantly lower for clients receiving continuous care than for clients receiving discontinuous care. The number of police contacts of clients receiving PMHC coordination per month was found to be a significant predictor of the percentage of clients in continuous care. CONCLUSION: The number of police contacts of clients can be used as a performance indicator for an urban PMHC system to evaluate the continuity of care in the PMHC system. PMID- 29450599 TI - A typology of satisfaction with mental health services based on Andersen's behavioral model. AB - OBJECTIVE: Patients with mental disorders (MDs) form a highly heterogeneous group, whose satisfaction with mental health services (MHS) may vary according to different variables. Identifying patient subgroups with similar levels of satisfaction may help identify variables that contribute to satisfaction or dissatisfaction with services. This study established a typology of patient satisfaction with MHS that revealed variables specific to each group. METHODS: The study included 325 patients with MDs across four health service networks offering integrated and diversified services. Data were collected using five standardized instruments, and participant medical records. A conceptual framework was developed, based on Andersen's Behavioral Model, which integrates socio demographic, clinical, needs-related and service use variables. Using cluster analysis, a typology of patient satisfaction was created. RESULTS: Analyses yielded four patient clusters: two where levels of satisfaction were relatively high and two with lower levels of satisfaction (range 3.74-4.37). Greater care continuity and higher income related to greater patient satisfaction; whereas co occurring MDs and substance use disorders (SUD), as well as more numerous and severe needs, characterized dissatisfied patients who were frequent users of MHS. CONCLUSIONS: Results highlight the need for continuity of care and adequate socio economic conditions for increasing patient satisfaction with MHS. Lower levels of satisfaction among patients with common MDs and SUDs suggest the importance of addressing their specific needs to enhance satisfaction and MH recovery. PMID- 29450600 TI - Sexual orientation disparities in the co-occurrence of substance use and psychological distress: a national population-based study (2008-2015). AB - PURPOSE: Although strong evidence documents the elevated prevalence of both substance use and mental health problems among sexual minorities (i.e., gay, lesbian, and bisexuals), relatively less research has examined whether risk of the co-occurrence of these factors is elevated among sexual minorities compared to heterosexuals. The object of this study was to (1) explore sexual orientation based differences in substance use, psychological distress, and their co occurrence in a representative sample in Sweden, and (2) examine if greater exposure to stressors, such as discrimination, victimization/threats, and social isolation, could explain these potential disparities and their co-occurrence. METHODS: Data come from the cross-sectional Swedish National Public Health Survey, which collected random samples of individuals (16-84 years of age) annually from 2008 to 2015, with an overall response rate of 49.7% (n = 79,568 individuals; 1673 self-identified as lesbian, gay, or bisexual). Population-level sexual orientation differences in substance use (i.e., alcohol, tobacco, and cannabis) and psychological distress were examined. RESULTS: Our findings showed significantly elevated prevalence of high-risk alcohol use, cannabis use, and daily tobacco smoking, among sexual minorities compared to heterosexuals. These substantial disparities in substance use more often co-occurred with psychological distress among sexual minorities than among heterosexuals. The elevated risk of co-occurring psychological distress and substance use was most notable among gay men relative to heterosexual men (adjusted odds ratio [AOR] = 2.65, CI 1.98, 3.55), and bisexual women relative to heterosexual women (AOR = 3.01, CI 2.43, 3.72). Multiple mediation analyses showed that experiences of discrimination, victimization, and social isolation partially explained the sexual orientation disparity in these co-occurring problems. CONCLUSIONS: This study adds to a growing body of research showing that sexual minorities experience multiple threats to optimal health and points toward future interventions that address the shared sources of these overlapping health threats in stigma-related stress.

PMID- 29450601 TI - Usefulness of perfusion- and diffusion-weighted imaging to differentiate between pilocytic astrocytomas and high-grade gliomas: a multicenter study in Japan. AB - PURPOSE: Imaging findings of pilocytic astrocytoma (PA) vary widely, sometimes resembling those of high-grade glioma (HGG). This study aimed to identify the imaging parameters that can be used to differentiate PA from HGG. METHODS: Altogether, 60 patients with PAs and 138 patients with HGGs were included in the study. Tumor properties and the presence of hydrocephalus, peritumoral edema, and dissemination were evaluated. We also measured the maximum relative cerebral blood flow (rCBFmax) and volume (rCBVmax) and determined the minimum apparent diffusion coefficient (ADCmin) in the tumor's solid components. The relative T1 (rT1), T2 (rT2), and contrast-enhanced T1 (rCE-T1) intensity values were evaluated. Parameters were compared between PAs and HGGs using the Mann-Whitney U test. Receiver operating characteristic (ROC) curve analysis was also used to evaluate these imaging parameters. A value of P < .05 was considered to indicate significance. RESULTS: Intratumoral hemorrhage and calcification were observed in 10.0% and 21.7% of PAs, respectively. The rCBFmax and rCBVmax values were significantly lower in PAs (0.50 +/- 0.35, 1.82 +/- 1.21) than those in HGGs (2.98 +/- 1.80, 9.54 +/- 6.88) (P < .0001, P = .0002, respectively). The ADCmin values were significantly higher in PAs (1.36 +/- 0.56 * 10-3 mm2/s) than those in HGGs (0.86 +/- 0.37 * 10-3 mm2/s) (P < .0001). ROC analysis showed that the best diagnostic performance was achieved with rCBFmax. CONCLUSION: The rCBFmax, rCBVmax, and ADCmin can differentiate PAs from HGGs.

PMID- 29450605 TI - Abbreviated mpMRI protocol for diffuse liver disease: a practical approach for evaluation and follow-up of NAFLD. AB - AIM: Multiparametric magnetic resonance imaging (mpMRI) may help determine the metabolic profile of patients with obesity and metabolic syndrome in addition to their clinical and laboratory biomarkers for diagnosis and monitoring. An abbreviated mpMRI protocol may be a faster, less-costly, and easier to perform alternative for the diagnosis, treatment, and follow-up of patients with NAFLD and for use in clinical trials. OBJECTIVE: To evaluate an abbreviated mpMRI protocol tailored to analyze quantitative imaging features of patients with obesity and NAFLD and assess its use during treatment. METHODS: This prospective study included patients with obesity and NAFLD to perform a quantitative analysis of liver fat and iron content, stiffness, as well as the visceral adipose tissue (VAT) during the course of a physical exercise-based treatment regimen. RESULTS: Longitudinal improvements in imaging features were observed in patients with good response to treatment, in accordance with improvements in biochemical and anthropometric biomarkers. CONCLUSION: An abbreviated mpMRI protocol consisting of liver fat and iron quantification, MR elastography, and VAT measurements is a feasible, less-costly, and accessible option for screening and monitoring of patients with obesity, NAFLD, and metabolic syndrome. PMID- 29450606 TI - Combination transarterial chemoembolization and microwave ablation improves local tumor control for 3- to 5-cm hepatocellular carcinoma when compared with transarterial chemoembolization alone. AB - PURPOSE: To compare transarterial chemoembolization (TACE) monotherapy to combination TACE and microwave ablation (MWA) for local control of 3- to 5-cm hepatocellular carcinoma (HCC). METHODS: Patients with HCC between 3 and 5 cm treated with TACE monotherapy or combination TACE + MWA at a single institution between 2007 and 2016 were retrospectively reviewed. Twenty-four HCCs (median diameter 3.8 cm) in 16 patients (13 males; median age 64 years) were treated using TACE monotherapy. Combination TACE + MWA was used to treat 23 HCCs (median diameter 4.2 cm) in 22 patients (18 males; median age 61 years). Microwave ablation was performed at a target time of two weeks following TACE. Individual tumors were followed by serial contrast-enhanced CT or MR. Response to treatment was evaluated on a tumor-by-tumor basis using mRECIST criteria with the primary outcome being local tumor progression (LTP). Data were analyzed using Fisher's exact test for categorical variables and Wilcoxon rank sum test for continuous variables. Time to LTP was estimated with the Kaplan-Meier method. RESULTS: Relative to TACE monotherapy, TACE + MWA provided a trend toward both a lower rate of LTP (34.8% vs. 62.5%, p = 0.11) and a higher complete response rate (65.2% vs. 37.5%; p = 0.12). Time to LTP (22.3 months vs. 4.2 months; p = 0.001) was significantly longer in the TACE + MWA group compared to TACE monotherapy. CONCLUSIONS: Combination therapy with TACE and microwave ablation improves local control and increases time to LTP for 3-5 cm HCC. PMID- 29450607 TI - The "caput medusae" sign in portal hypertension. PMID- 29450608 TI - Imaging findings of ovarian dysgerminoma with emphasis on multiplicity and vascular architecture: pathogenic implications. AB - We report the imaging findings of three ovarian dysgerminomas that coexisted with other germ cell tumors or gonadoblastomas, focusing on the distribution of tumor nests and vascular architecture, which might provide information about the pathogenesis of dysgerminomas. In a 14-year-old female with dysgerminoma and coexisting gonadoblastomas, contrast-enhanced magnetic resonance imaging (MRI) demonstrated a solid mass in the right ovary, which presented as hyperintense lobules on diffusion-weighted imaging separated by fibrovascular septa. Some small nodules were found to exist separately from the lobules (multiplicity) and to include pathological remnants of gonadoblastoma. Large tumor vessels were present at the center of the mass (central blood vessels), which were in direct contact with the ovarian veins and radiated peripherally through the fibrovascular septa. In a 35-year-old female, a mixed germ cell tumor, which was mainly composed of dysgerminoma and yolk sac tumor foci, exhibited the same vascular architecture pattern as the first dysgerminoma on contrast-enhanced computed tomography. In a 10-year-old female with a mixed germ cell tumor, contrast-enhanced MRI revealed an enlarged left ovary, which contained a large heterogeneous mass and multiple tiny nodules (multiplicity). Microscopically, the former corresponded to a yolk sac tumor, and the latter corresponded to a dysgerminoma containing remnants of gonadoblastoma. Based on these cases, the presence of tumor nest multiplicity and central blood vessels might aid the diagnosis of dysgerminoma, and these imaging findings might be indicative of the synchronous development of multiple dysgerminomas from primordial germ cells or gonadoblastomas. PMID- 29450593 TI - Comparison of European ICU patients in 2012 (ICON) versus 2002 (SOAP). AB - PURPOSE: To evaluate differences in the characteristics and outcomes of intensive care unit (ICU) patients over time. METHODS: We reviewed all epidemiological data, including comorbidities, types and severity of organ failure, interventions, lengths of stay and outcome, for patients from the Sepsis Occurrence in Acutely ill Patients (SOAP) study, an observational study conducted in European intensive care units in 2002, and the Intensive Care Over Nations (ICON) audit, a survey of intensive care unit patients conducted in 2012. RESULTS: We compared the 3147 patients from the SOAP study with the 4852 patients from the ICON audit admitted to intensive care units in the same countries as those in the SOAP study. The ICON patients were older (62.5 +/- 17.0 vs. 60.6 +/- 17.4 years) and had higher severity scores than the SOAP patients. The proportion of patients with sepsis at any time during the intensive care unit stay was slightly higher in the ICON study (31.9 vs. 29.6%, p = 0.03). In multilevel analysis, the adjusted odds of ICU mortality were significantly lower for ICON patients than for SOAP patients, particularly in patients with sepsis [OR 0.45 (0.35-0.59), p < 0.001]. CONCLUSIONS: Over the 10-year period between 2002 and 2012, the proportion of patients with sepsis admitted to European ICUs remained relatively stable, but the severity of disease increased. In multilevel analysis, the odds of ICU mortality were lower in our 2012 cohort compared to our 2002 cohort, particularly in patients with sepsis. PMID- 29450609 TI - Effect of gantry rotation speed and scan mode on peristalsis motion artifact frequency and severity at abdominal CT. AB - PURPOSE: The purpose of the study was to understand the effect of CT gantry speed and axial vs. helical scan mode on the frequency and severity of bowel peristalsis artifacts. METHOD: We retrospectively identified 150 oncologic abdominopelvic CT scans obtained on a 256 slice CT scanner: 50 scans obtained with Axial mode and 0.5-s gantry rotation time (Slow-Axial); 50 with Axial mode and 0.28-s gantry rotation time (Fast-Axial); and 50 scans with Helical mode and 0.28-s gantry rotation time (Fast-Helical). The patients included 74 women and 76 men with a mean age of 61 years (range 22-85 years). Two readers viewed all CT scans to record the presence and severity of bowel peristalsis artifact, location of artifact (stomach, duodenum/jejunum, ileum, and colon) and artifact location relative to bowel interface (gas-bowel, fluid-bowel, and gas-fluid). The severity of artifacts was recorded subjectively on a 3-point scale, and objectively based on maximum length of the artifact. RESULTS: Peristalsis artifact was more commonly seen with Slow-Axial scan acquisition (37 of 50 patient scans, or 74%) than Fast-Axial (15 in 50 patient scans, or 30%, p < 0.001) and Fast-Helical (22 of 50 patient scans, or 44%, p < 0.005). The bowel segment distribution and severity of peristalsis artifacts were not significantly different between scan techniques. CONCLUSION: Peristalsis artifacts are common at abdominopelvic CT scans. Fast gantry rotation speed significantly reduces the frequency of bowel peristalsis artifacts and should be a consideration when imaging of bowel and structures near bowel is critical. PMID- 29450610 TI - CTC technique: methods to ensure an optimal exam. AB - CT colonography (CTC) has demonstrated equivalent accuracy to optical colonoscopy in the detection of clinically relevant polyps and tumors but this is only possible when technique is optimized. The two most important features of a high quality CTC are a well-prepared colon and a distended colon. This article will discuss the dietary, bowel preparation, and fecal/fluid tagging options to best prepare the colon. Strategies to optimally distend the colon will also be discussed. CT scan techniques including patient positioning and radiation dose optimization will be reviewed. With proper technique which includes sufficient bowel preparation, fecal/fluid tagging, bowel distension, and optimized scan technique, high-quality CTC examinations should become more feasible, easier to interpret, and more consistently reproducible leading to increased utilization and increased referrals. PMID- 29450611 TI - High spatial resolution navigated 3D T1-weighted hepatobiliary MR cholangiography using Gd-EOB-DTPA for evaluation of biliary anatomy in living liver donors. AB - PURPOSE: To determine the feasibility of high-resolution navigated three dimensional (3D) T1-weighted hepatobiliary MR cholangiography (Nav T1 MRC) using Gd-EOB-DTPA for biliary visualization in living liver donors and to assess added value of 3D T1-weighted hepatobiliary MRCs in improving the confidence and diagnostic accuracy of biliary anatomy in complementary to T2-weighted MRCs. METHODS: Twenty-nine right liver donors underwent 3D T2 MRC, 2D T2 MRC, breath hold T1-weighted hepatobiliary MRC (BH T1 MRC), and Nav T1 MRC. Two readers independently reviewed and compared 3D/2D MRC set, added BH T1 MRC set, and added Nav T1 MRC set for biliary diagnostic accuracy and confidence. For each MRC, biliary segments visualization and image quality were scored. RESULTS: Both BH T1 MRC and Nav T1 MRC improved accuracy and specificity in biliary diagnosis when added to 3D/2D T2 MRC-alone set, though without statistical significance (R1, 82.8% to 93.1%; R2, 82.8% to 89.7%). The added Nav T1 MRC set showed the highest diagnostic confidence with both readers. Both readers scored Nav T1 MRC with the highest visualization scores for branching ducts and overall ducts. CONCLUSION: Combining T1-weighted hepatobiliary MRCs to 3D/2D T2 MRC set improved accuracy for biliary anatomy diagnosis; time-efficient BH T1 MRC in axial and coronal planes should be considered as a key MRC sequence complementary to T2 MRCs. Given excellent biliary visualization and superior diagnostic confidence, Nav T1 MRC in selected subjects with breath-hold difficulties and inconclusive or complex biliary variations may assist in reaching a correct biliary diagnosis. PMID- 29450612 TI - The "serpent sign" in hydatid disease. PMID- 29450613 TI - Extracolonic findings and radiation at CT colonography: what the referring provider needs to know. AB - A better understanding of the risks and benefits of extracolonic findings and radiation dose will aid in the safe and proper implementation of CT colonography in clinical practice. The majority of extracolonic findings in screening patients are benign and can be ignored by referring physicians. Radiologists also need to be responsible in reporting extracolonic findings. Referring providers must be knowledgeable about the theoretic risks and controversies regarding the use of ionizing radiation. Screening CT colonography imparts a low-level of radiation to patients that is equivalent or less than annual background dose. PMID- 29450614 TI - White liver sign.

AB - The introduction of ultrasound contrast agents has rendered contrast-enhanced ultrasound (CEUS) a valuable complementary technique to address clinically significant problems. This pictorial review describes the use of CEUS guidance in abdominal intervention and illustrates such application for a range of clinical indications. Clinical application of CEUS discussed include commonly performed abdominal interventional procedures, such as biopsy, drainage, nephrostomy, biliary intervention, abdominal tumor ablation and its subsequent monitoring, and imaging of vascular complications following abdominal intervention. The purpose of this article is to further familiarize readers with the application of CEUS, particularly its specific strength over alternative imaging modalities, in abdominal intervention. PMID- 29450616 TI - Early motor signs of autism spectrum disorder in spontaneous position and movement of the head. AB - We examined the characteristics of spontaneous movements at 9-20 weeks postterm age in very low birth-weight infants who later developed autism spectrum disorder (ASD). We analyzed video recordings of spontaneous movements of 39 children who had no clinical issues [typically developing (TD) group], 21 children who showed developmental delay, and 14 children who were diagnosed with ASD (ASD group) at 6 years of age. Head position in each video frame was classified by visual inspection. The percentage of midline head position (PMHP) and number of changes in head position were calculated. Spontaneous limb movements were quantified using six indices. The values of PMHP were significantly lower in the ASD group than in the TD group. The lower PMHP during early infancy is associated with later development of ASD. Poorer performance in maintaining midline position of the head at this period may distinguish infants who later develop ASD from those who show TD. PMID- 29450617 TI - A natural variant of arylsulfatase from Kluyveromyces lactis shows no formylglycine modification and has no enzyme activity. AB - Kluyveromyces lactis is a common fungal microorganism used for the production of enzyme preparations such as beta-galactosidases (native) or chymosin (recombinant). It is generally important that enzyme preparations have no unwanted side activities. In the case of beta-galactosidase preparations produced from K. lactis, an unwanted side activity could be the presence of arylsulfatase (EC 3.1.6.1). Due to the action of arylsulfatase, an unpleasant "cowshed-like" off-flavor would occur in the final product. The best choice to avoid this is to use a yeast strain without this activity. Interestingly, we found that certain natural K. lactis strains express arylsulfatases, which only differ in one amino acid at position 139. The result of this difference is that K. lactis DSM 70799 (expressing R139 variant) shows no arylsulfatase activity, unlike K. lactis GG799 (expressing S139 variant). After recombinant production of both variants in Escherichia coli, the R139 variant remains inactive, whereas the S139 variant showed full activity. Mass spectrometric analyses showed that the important posttranslational modification of C56 to formylglycine was not found in the R139 variant. By contrast, the C56 residue of the S139 variant was modified. We further investigated the packing and secondary structure of the arylsulfatase variants using optical spectroscopy, including fluorescence and circular dichroism. We found out that the inactive R139 variant exhibits a different structure regarding folding and packing compared to the active S139 variant. The importance of the amino acid residue 139 was documented further by the construction of 18 more variants, whereof only ten showed activity but always reduced compared to the native S139 variant. PMID- 29450618 TI - Influence of membrane fatty acid composition and fluidity on airborne survival of Escherichia coli. AB - Finding ways to predict and control the survival of bacterial aerosols can contribute to the development of ways to alleviate a number of crucial microbiological problems. Significant damage in the membrane integrity of Escherichia coli during aerosolization and airborne suspension has been revealed which has prompted the question of how the membrane fatty acid composition and fluidity influence the survival of airborne bacteria. Two approaches of using isogenic mutants and different growth temperatures were selected to manipulate the membrane fatty acid composition of E. coli before challenging the bacteria with different relative humidity (RH) levels in an aerosol chamber. Among the mutants (fabR - , cfa. fadA - ), fabR - had the lowest membrane fluidity index (FI) and generally showed a higher survival than the parental strain. Surprisingly, its resistance to airborne stress was so strong that its viability was fully maintained even after airborne suspension at 40% RH, a harsh RH level to bacterial survival. Moreover, E. coli cultured at 20 degrees C with a higher FI than that at 30 and 37 degrees C generally had a lower survival after aerosolization and airborne suspension. Unlike FI, individual fatty acid and cyclopropane fatty acid composition did not relate to the bacterial survival. Lipid peroxidation of the membrane was undetected in all the bacteria. Membrane fluidity plays a stronger role in determining the bacteria survival during airborne suspension than during aerosolization. Certain relationships between FI and bacteria survival were identified, which could help predict the transmission of bacteria under different conditions. PMID- 29450620 TI - Targeting the neddylation pathway in cells as a potential therapeutic approach for diseases. AB - The ubiquitin-proteasome system (UPS) is an important system that regulates the balance of intracellular proteins, and it is involved in the regulation of multiple vital biological processes. The approval of bortezomib for relapsed and refractory multiple myeloma has proven that agents targeting the UPS have the potential to be effective treatment strategies for diseases. Among of all of the components of the UPS, cullin-RING ligases (CRLs) are the focus of research. CRLs are the largest family of ubiquitin E3 ligases and they play a critical role in substrate binding. CRL activity is modulated by many pathways in which neddylation modification is the essential process for cullin activation. Thus, targeting the neddylation pathway of cullins could indirectly affect CRL activity, thereby interfering with substrate protein ubiquitination. In addition to cullin proteins, there are some other target proteins of neddylation, such as p53, mouse double minute 2, and epidermal growth factor receptor. For target proteins, neddylation modification mainly causes functions changes, not degradation. In addition, the level of neddylation is also closely related to disease development and prognosis. In this review, we summarize the research on some target proteins and active target agents of neddylation pathways, and explore the role of neddylation in disease therapy. We came to the conclusion that conducting research on neddylation may be a potential approach to discover some novel targets and agents that could be effective without serious side effects. PMID- 29450619 TI - Immediate response mechanisms of Gram-negative solvent-tolerant bacteria to cope with environmental stress: cis-trans isomerization of unsaturated fatty acids and outer membrane vesicle secretion. AB - Bacteria have evolved an array of adaptive mechanisms enabling them to survive and grow in the presence of different environmental stresses. These mechanisms include either modifications of the membrane or changes in the overall energy status, cell morphology, and cell surface properties. Long-term adaptations are dependent on transcriptional regulation, the induction of anabolic pathways, and cell growth. However, to survive sudden environmental changes, bacterial short term responses are essential to keep the cells alive after the occurrence of an environmental stress factor such as heat shock or the presence of toxic organic solvents. Thus far, two main short-term responses are known. On the one hand, a fast isomerization of cis into trans unsaturated fatty leads to a quick rigidification of the cell membrane, a mechanism known in some genera of Gram negative bacteria. On the other hand, a fast, effective, and ubiquitously present countermeasure is the release of outer membrane vesicles (OMVs) from the cell surface leading to a rapid increase in cell surface hydrophobicity and finally to the formation of cell aggregates and biofilms. These immediate response mechanisms just allow the bacteria to stay physiologically active and to employ long-term responses to assure viability upon changing environmental conditions. Here, we provide insight into the two aforementioned rapid adaptive mechanisms affecting ultimately the cell envelope of Gram-negative bacteria. PMID- 29450621 TI - NGF protects corneal, retinal, and cutaneous tissues/cells from phototoxic effect of UV exposure. AB - PURPOSE: Based on evidence that nerve growth factor (NGF) exerts healing action on damaged corneal, retinal, and cutaneous tissues, the present study sought to assess whether topical NGF application can prevent and/or protect epithelial cells from deleterious effects of ultraviolet (UV) radiation. METHODS: Eyes from 40 young-adult Sprague Dawley rats and cutaneous tissues from 36 adult nude mice were exposed to UVA/B lamp for 60 min, either alone or in the presence of murine NGF. Corneal, retinal, and cutaneous tissues were sampled/processed for morphological, immunohistochemical, and biomolecular analysis, and results were compared statistically. RESULTS: UV exposure affected both biochemical and molecular expression of NGF and trkANGFR in corneal, retinal, and cutaneous tissues while UV exposure coupled to NGF treatment enhanced NGF and trkANGFR expression as well as reduced cell death. CONCLUSIONS: Overall, the findings of this in vivo/ex vivo study show the NGF ability to reduce the potential UV damage. Although the mechanism underneath this effect needs further investigation, these observations prospect the development of a pharmacological NGF-based therapy devoted to maintain cell function when exposed to phototoxic UV radiation. PMID- 29450623 TI - [Statement of the BVA and DOG on eye examinations in patients with high visual defects : Status January 2018]. PMID- 29450624 TI - [Intraoperative optical coherence tomography in explorative vitrectomy in patients with vitreous haemorrhage-a case series]. AB - BACKGROUND: High-resolution spectral domain optical coherence tomography (SD-OCT) is a gold standard technique for diagnosis, management and monitoring of patients with vitreoretinal diseases. Preoperative diagnostics for evaluation of intraocular and retinal status in patients with vitreous haemorrhage are limited, thus final therapeutic decisions can only be made during explorative vitrectomy. We evaluated the use of intraoperative SD-OCT (iSD-OCT) as a real-time additional diagnostic tool during explorative vitrectomy in patients with vitreous haemorrhage. METHODS: We report on 9 patients (11 eyes) with vitreous haemorrhage. Preoperative ultrasound was performed to evaluate intraocular status. Subsequently, an explorative 23G pars plana vitrectomy was performed under visualisation with the OPMI Lumera 700 surgical microscope (Carl Zeiss Meditec, Jena, Germany) equipped with a fully integrated iSD-OCT device (Rescan 700, Carl Zeiss Meditec, Jena, Germany) as a real-time diagnostic tool. RESULTS: In all patients, intraoperative iSD-OCT allowed real-time evaluation of the preretinal, intraretinal and subretinal structures in addition to the intraoperative en face image. The further surgical strategy, i. e. necessity for peeling of epiretinal membranes (ERM) or of the inner limiting membrane (ILM), application of intravitreal medication and selection of the appropriate tamponade, was based on and optimised according to the iSD-OCT images. CONCLUSION: Intraoperative iSD-OCT is highly useful as an additional intraoperative diagnostic tool in patients with vitreous haemorrhage. In addition to the en face microscope image, it facilitates intraoperative real-time diagnosis and aids therapeutic decision-making during surgery. PMID- 29450622 TI - Comparison of retinal microvascular changes in eyes with high-tension glaucoma or normal-tension glaucoma: a quantitative optic coherence tomography angiographic study. AB - PURPOSE: The aim of this study is to determine and compare the changes in the retinal vasculature in eyes with high-tension glaucoma (HTG) or normal-tension glaucoma (NTG). METHODS: The right eyes of 43 HTG subjects, 33 NTG subjects, and 51 age- and sex-matched normal subjects were included in this cross-sectional study. Signals were projected from the internal limiting membrane to retinal pigment epithelium. The retinal perfused vessel densities in the peripapillary and parafoveal regions were measured automatically with optic coherence tomography angiography and the split-spectrum amplitude-decorrelation angiography algorithm. RESULTS: Compared with normal eyes, glaucomatous eyes had a smaller retinal nerve fibre layer (RNFL) thickness, smaller full parafoveal retinal thickness, and lower retinal perfused vessel density (PVD) in the peripapillary and parafoveal regions (all P < 0.01). The visual field, RNFL and retinal thicknesses, and PVD in the parafoveal region in the HTG eyes were similar to those in the NTG eyes. However, the NTG eyes had a significantly lower mean PVD than the HTG eyes in the peripapillary region. When the different sectors of the peripapillary region were studied, the difference was still significant in most sectors (all P < 0.05), except the inferotemporal sector (P = 0.676). CONCLUSIONS: The retinal perfused vessel density is significantly reduced in HTG and NTG eyes, and more prominently in the peripapillary region in NTG eyes. PMID- 29450625 TI - Mechanical Thrombectomy in Patients with Acute Ischemic Stroke on Anticoagulation Therapy. AB - INTRODUCTION/PURPOSE: Mechanical thrombectomy (MT) for acute ischemic stroke (IS) can be performed also in patients on anticoagulation therapy (AT); however, sufficient and reliable data about safety and efficacy of MT are still missing. Thus, we aimed to compare these parameters between patients treated on AT and without AT. MATERIALS AND METHODS: All consecutive IS patients treated with MT using stent retrievers were included in the retrospective analysis. Neurological deficit was scored using National Institutes of Health Stroke Scale (NIHSS) and 90-day clinical outcome using modified Rankin scale with a score 0-2 for good outcome. Recanalization was rated using Thrombolysis in Cerebral Infarction (TICI) scale. Symptomatic intracerebral hemorrhage (SICH) was assessed according to the SITS-MOST criteria. RESULTS: Out of 703 patients treated with MT, 88 (12.5%) patients (46% males, mean age 75.5 +/- 11.8 years) were on AT with an admission median NIHSS of 17 points. Recanalization (TICI 2b-3) was achieved in 80% and complete (TICI 3) in 65% of patients on AT and in 80 and 65% of patients without AT (p-1.000). SICH after MT was detected in 9% of AT and 5% of non-AT patients (p-0.136). Good outcome was present in 36% of AT patients (p-0.03). AT patients with poor outcome had more frequently atrial fibrillation (93%, p 0.005), higher admission NIHSS (17, p-0.004) and higher rate of SICH (14.5%, p 0.047). CONCLUSION: MT seems to be safe also in patients on AT. Poor outcome may be related to higher admission NIHSS, higher rate of SICH and presence of atrial fibrillation.

PMID- 29450627 TI - Can the use of a single integrated unitary autonomic index provide early clues for eventual eligibility for olympic games? AB - PURPOSE: Optimal autonomic regulation and stress resilience might be considered critical elements of athletic performance. We hypothesize that a novel unitary autonomic index for sports (ANSIs), together with a somatic stress related symptom score (4SQ) might help characterize athletes who were eventually selected for the Rio 2016 Olympic Games Italian team (Rio +). METHODS: In this retrospective study we examined 778 athletes (age 24.4 +/- 6.7 yrs) who underwent a planned yearly pre-participation screening. All athletes underwent clinical, autonomic and exercise ECG evaluation. The combination of vagal and sympathetic indices from RR variability into ANSIs was performed by radar plot and percent ranking of index variables. We assessed (Rio +) versus (Rio -) athletes also after subdivision into three sport intensity groups (low, mid and high intensity). RESULTS: Overall there were no significant differences between (Rio +) and (Rio -) athletes when considering individual spectral derived variables. Conversely, the unitary Index ANSIs was significantly higher in (Rio +) compared to (Rio -) athletes (respectively 54.5 +/- 29.5 and 47.9 +/- 28.4 p = 0.014). This difference was particularly evident (p = 0.017) in the group of athletes characterized by both high static and dynamic components. 4SQ was smaller in the (Rio +) group, particularly in the groups of athletes characterized by both low medium static and dynamic components. CONCLUSIONS: ANSIs, a proxy of integrated cardiac autonomic regulation and simple assessment of resilience to stress, may differentiate Italian athletes who were eventually selected for participation in the 2016 Rio Olympic Games from those who were not, suggesting the possibility of a "winning functional phenotype".

AB - BACKGROUND: Ehler-Danlos syndome (EDS) refers to a group of heritable connective tissue disorders; rare manifestations of which are cervical kyphosis and clinical myelopathy. Surgical treatment is described for the deformity in the thoracolumbar spine in adolescents but not for infantile cervical spine. Internal fixation for deformity correction in the infantile cervical spine is challenging due to the diminutive size of the bony anatomy and the lack of spinal instrumentation specifically designed for young children. We describe the first case of successful surgical treatment in an infant with a high cervical kyphotic deformity in EDS. CASE PRESENTATION: A 15-month-old female with EDS presented with several months of regression in gross motor skills in all four extremities. Imaging demonstrated 45 degrees of kyphosis from the C2-4 levels with spinal cord compression. Corrective surgery consisted of a C3 corpectomy and C2-4 anterior fusion with allograft block and anterior fixation with dual 2 * 2 hole craniofacial miniplates, supplemented by C2-4 posterior fusion using four craniofacial miniplates fixated to the lamina. Radiographs at 20 months post surgery demonstrated solid fusion both anteriorly and posteriorly with maintenance of correction. CONCLUSIONS: Ehlers-Danlos syndrome may present in the pediatric population with congenital kyphosis from cervical deformity in addition to the more commonly seen thoracolumbar deformities. PMID- 29450630 TI - Outermost layer-oriented medial approach for infrapyloric nodal dissection in laparoscopic distal gastrectomy. AB - BACKGROUND: Based on our experience of suprapancreatic nodal dissection in laparoscopic gastrectomy, we developed an outermost layer-oriented medial approach for infrapyloric nodal dissection. The objective of this single institution retrospective study was to determine the feasibility, safety, and reproducibility of this novel and unique dissection procedure. METHODS: This approach can be performed in the same manner as suprapancreatic nodal dissection but by replacing the left gastric artery with the right gastroepiploic artery (RGEA), the common hepatic artery with the anterior superior pancreaticoduodenal artery (ASPDA), and the splenic artery with the gastroduodenal artery. It comprises five steps: (1) mobilization of the transverse mesocolon along the prepancreatic membrane, (2) medial dissection along the dissectable layer between the pancreatic head and the dorsal side of the right gastroepiploic vein (RGEV), (3) division of the RGEV and determination of the lateral and cranial borders, (4) dissection along the outermost layer of the RGEA and ASPDA and transection of the infrapyloric artery and RGEA, and (5) transection of the duodenal bulb. RESULTS: This novel method was applied in 112 patients who underwent laparoscopic distal gastrectomy from 2014 to 2015. The anatomical landmarks that we determined to appropriately identify the outermost layer were highly reproducible, and our novel procedure based on these landmarks was successfully completed in all cases, without any intraoperative complications. Furthermore, in all cases, no. 6 lymph nodes were fully and adequately dissected within the infrapyloric area anatomically defined in the Japanese Classification of Gastric Carcinoma ver. 14. Pancreatic fistula occurred only in 1.8% cases. CONCLUSIONS: This novel outermost layer-oriented medial approach is a robust procedure that may help laparoscopic surgeons in performing safe and reproducible infrapyloric nodal dissection. PMID- 29450631 TI - Preoperative combination of progressive pneumoperitoneum and botulinum toxin type A in patients with loss of domain hernia. AB - INTRODUCTION: Preoperative progressive pneumoperitoneum (PPP) and botulinum toxin type A (BT) are tools in the surgical preparation of patients with loss of domain hernias (LODH). The aim of this paper is to report our experience with these preoperative techniques in 70 patients with LODH. METHODS: Observational study of 70 consecutive patients with LODH was conducted between May 2010 and May 2016. Diameters of the hernia sac, incisional hernia (VIH), and abdominal cavity (VAC) volumes, and VIH/VAC ratio were measured before and after PPP and BT, using abdominal CT scan data. Combination of both techniques was performed when the VIH/VAC ratio was > 20%. RESULTS: Median insufflated volume of air for PPP was 8450 +/- 3400 cc (4500-13,450), over a period of 11.3 +/- 2.3 days (9-16). BT administration time was 38.1 +/- 3.7 days (35-44). An average reduction of 16.6% of the VIH/VAC ratio after PPP and BT was obtained (p < 0.05). Complications associated with PPP were 20%, and with surgical technique 29.6%. No complications occurred during the BT administration. Reconstructive technique was anterior CST in 54 patients, TAR in 14 cases and Rives-Stoppa technique in two patients. Median follow-up was 34.5 +/- 22.3 months (12-60) and four cases of hernia recurrence (5.7%) were reported. CONCLUSIONS: Using a CT volumetric protocol, combination of PPP and BT decreases the VIH/VAC ratio and hernia defect diameters, which constitutes a key factor in the treatment of LODH.

AB - PURPOSE: MID1 is an E3 ubiquitin ligase that was first found in Opitz G/BBB syndrome, but there has been little research into its role in lung diseases. We have found an accumulating evidence that indicates the MID1-PP2A complex plays a role in asthma and contributes to inflammation, but its roles in lung adenocarcinoma are unclear. This study aimed at evaluating the function of MID1 PP2A complex in human lung adenocarcinoma. METHODS: We used western blot, ELISA and real-time quantitative PCR to detect the protein and mRNA levels of MID1 and PP2A in A549, H1975, and H1650 lung adenocarcinoma cell lines compared with the human bronchial epithelial cell line BEAS-2B. Additionally, we used IHC, ELISA and real-time quantitative PCR to dectect MID1 and PP2A levels in 30-paired lung adenocarcinoma tissues. We also detected apoptosis, proliferation and cell cycle related protein expression after silencing MID1 and activing PP2A. RESULTS: Our data show that MID1 was significantly upregulated in 30-paired lung adenocarcinoma tissues, and in A549, H1975 and H1650 cell lines compared with BEAS-2B. PP2A showed the opposite results. Furthermore, both upregulated MID1 and downregulated PP2A were correlated with age, but not sex, TNM stage or smoking history. In vitro experiments showed that PP2A was upregulated in lung adenocarcinoma cell lines that were transfected with MID1-siRNA, suggesting MID1 negatively regulates PP2A in lung adenocarcinoma. We also found that silencing MID1 expression or activating PP2A induced apoptosis, proliferation and cell cycle arrest. CONCLUSIONS: We demonstrated that the MID1-PP2A complex plays an important role in lung adenocarcinoma, influencing cell cycle progression, proliferation and apoptosis. Our findings showed a novel molecular mechanism of lung tumorigenesis that may provide new insights for anti-tumor therapies. PMID- 29450634 TI - Prevalence, genotypes, and risk factors of Enterocytozoon bieneusi in Asiatic black bear (Ursus thibetanus) in Yunnan Province, Southwestern China. AB - Microsporidiosis is an important zoonotic disease, even leading to severe diarrhea. However, no information about prevalence and genotypes of Enterocytozoon bieneusi infection in Asiatic black bears in southwestern China is available. The objectives of the present study were to investigate the prevalence of E. bieneusi and to characterize their genotypes using the nested PCR amplification of the internal transcribed spacer region of the ribosomal RNA gene cluster and multilocus sequence typing (MLST). The overall prevalence of E. bieneusi was 19.75% (80/405) and the rate of E. bieneusi in Xishuangbanna (33.33%) was significantly higher than that in any other regions (Honghe, 17.65%; Dehong, 13.04%; Kunming, 0; P = 0.01). Sequence analysis revealed that 4 known genotypes (D, n = 2; SC02, n = 10; SC01, n = 5; and CHB1, n = 4) and 13 novel genotypes (designed MJ1-MJ13) were identified. When 17, 5, 14, and 34 sequences at loci MS1, MS3, MS4, and MS7 via MLST analyses, representing 4, 4, 5, and 10 genotypes, respectively, were completed, one multilocus genotype (MLG novel-ABB1) was identified. This is the first report of E. bieneusi in Asiatic black bear in Yunnan province, Southwestern China. The results indicated the potential zoonotic risk of this parasite through the Asiatic black bear in this region and provided foundation data for preventing and controlling E. bieneusi infection of many other animals and humans in these regions. PMID- 29450635 TI - Screening in spouses of colorectal cancer patients: a missed opportunity. AB - BACKGROUND: Spouses of colorectal cancer (CRC) patients could be at increased risk of developing CRC due to shared lifestyle habits with the patients which is a notable risk factor. This study explores the various issues surrounding CRC screening among these spouses. METHODS: A mixed method study comprising in-depth qualitative semi-structured interviews followed by structured quantitative questionnaire was administered to spouses who accompanied CRC patients during their appointments, from January 2016 to February 2017. RESULTS: Fifty spouses of CRC patients, median age of 60 (range, 41-82) years, were qualitatively interviewed but 5 of them did not complete the questionnaire. Only 26 (57.8%) of them were current with CRC screening. Data saturation was reached at the 48th participant. Four main themes emerged from the qualitative interviews. These included (i) adequacy of knowledge and attitudes about CRC screening, (ii) suboptimal public health promotion efforts of CRC screening, (iii) barriers of CRC screening, and (iv) need for mutual spousal support. From the questionnaires, spouses who were not current with CRC screening were more likely to report more barriers and have different cues to actions than those who are current. The majority of the spouses demonstrated high levels of knowledge on CRC, understood its severity and their susceptibility. CONCLUSION: Spouses exhibit high levels of knowledge and awareness of the implications of CRC. Apart from addressing psychological issues during the acute phases, targeted interventions should be considered to improve their screening rates and to use them as advocates for CRC screening among family and community. PMID- 29450636 TI - Comparing the efficacy of low-dose vs high-dose cyclophosphamide regimen as induction therapy in the treatment of proliferative lupus nephritis: a single center study. AB - : Cyclophosphamide (CYC) has been the backbone immunosuppressive drug to achieve sustained remission in lupus nephritis (LN). The aim was to evaluate the efficacy and compare adverse effects of low and high dose intravenous CYC therapy in Indian patients with proliferative lupus nephritis. An open-label, parallel group, randomized controlled trial involving 75 patients with class III/IV LN was conducted after obtaining informed consent. The low dose group (n = 38) received 6 * 500 mg CYC fortnightly and high dose group (n = 37) received 6 * 750 mg/m2 CYC four-weekly followed by azathioprine. The primary outcome was complete/partial/no response at 52 weeks. The secondary outcomes were renal and non-renal flares and adverse events. Intention-to-treat analyses were performed. At 52 weeks, 27 (73%) in high dose group achieved complete/partial response (CR/PR) vs 19 (50%) in low dose (p = 0.04). CR was higher in the high dose vs low dose [24 (65%) vs 17 (44%)], although not statistically significant. Non responders (NR) in the high dose group were also significantly lower 10 (27%) vs low dose 19 (50%) (p = 0.04). The change in the SLEDAI (Median, IQR) was also higher in the high dose 16 (7-20) in contrast to the low dose 10 (5.5-14) (p = 0.04). There was significant alopecia and CYC-induced leucopenia in high dose group. Renal relapses were significantly higher in the low dose group vs high dose [9 (24%) vs 1(3%), (p = 0.01)]. At 52 weeks, high dose CYC was more effective in inducing remission with decreased renal relapses in our population. TRIAL REGISTRATION: The study was registered at http://www.clintrials.gov .

PMID- 29450638 TI - Religious coping and death depression in Iranian patients with cancer: relationships to disease stage. AB - PURPOSE: The study investigated relationships among the extent of disease, religious coping, and death depression in Iranian patients with cancer. METHOD: A descriptive cross-sectional study was conducted with a convenience sample of 482 Iranian cancer patients. Participants completed demographic and health, death depression, and religious coping surveys. RESULTS: After controlling for demographic and health characteristics, positive and negative religious coping behaviors were significantly related to the experience of death depression. There was an interaction effect between negative religious coping and extent of disease with significant positive relationships to the experience of death depression. CONCLUSIONS: Negative religious coping was found to be more closely associated with death depression in patients with earlier stage disease than those with advanced stages of cancer in this sample of patients with cancer from Iran. Findings support assessing patients for use of religious coping strategies. Muslim patients who are religiously alienated and have existential anguish may be vulnerable and need heightened support following diagnosis and during treatment of early stage cancer. PMID- 29450637 TI - Canakinumab treatment in children with familial Mediterranean fever: report from a single center. AB - Familial Mediterranean fever (FMF), the most common hereditary autoinflammatory disorder is characterized by recurrent episodes of fever, serositis, arthritis. The major long-term result is amyloidosis. Colchicine remains the principle of the treatment; it not only prevents the acute attacks but also prevents the long term complications such as amyloidosis; 5-10% of the patients are unresponsive to treatment. Recently new therapeutic options as anti-interleukin 1 agents are successfully used for the patients who do not respond to colchicine treatment. In this study, we retrospectively evaluated 11 pediatric colchicine-resistant FMF patients who were treated with canakinumab. Three of the patients had amyloidosis and two had uveitis. Based on our results, we suggest that canakinumab may be a safe and effective therapy in patients who are resistant to colchicine and even in the patients with amyloidosis. We also suggest that canakinumab might be a safe option for the patients with uveitis. PMID- 29450640 TI - Incidence of perioperative complications in total hip and knee arthroplasty in patients with Parkinson disease. AB - INTRODUCTION: The aim of this study is to evaluate the difference in perioperative complication rate in total hip, bipolar hemiarthroplasties and total knee arthroplasty in patients with Parkinson disease in trauma and elective surgery in our Musculoskeletal Center during a period of 10 years. MATERIAL AND METHOD: Between 2006 and 2016, 45 bipolar hemiarthroplasties in trauma surgery, 15 total knee and 19 total hip arthroplasties in patients with Parkinson's disease were performed. We divided the patients in two groups. Group I included trauma cases (45) and group II elective surgery cases (34). Complications were documented and divided into local minor and major complications and general minor and major complications. Fisher's exact test was used for statistical evaluation. RESULTS: In both groups, there was one local major complication (p > 0.05): In group I, there was one case of loosening of a K-wire which was removed operatively. In group II, there was one severe intraarticular bleeding requiring puncture of the hematoma. In group I, there were 38 general complications; in group II, there were 17 general complications. There was no statistical difference in complication rate (p > 0.05). CONCLUSION: Total hip arthroplasty, bipolar hemiarthroplasties and knee arthroplasty in patients with Parkinson disease is possible in elective and trauma surgery. Complication rate is higher in comparison with patients not suffering from Parkinson disease, but there is no difference in complication rate in elective and trauma surgery. Nevertheless, early perioperative neurological consultation in patients with Parkinson disease is recommended to minimize complications and improve early outcomes after arthroplasty. PMID- 29450641 TI - Chronic lymphocytic leukemia cells acquire regulatory B-cell properties in response to TLR9 and CD40 activation. AB - Circulating chronic lymphocytic leukemia (CLL) cells share phenotypic features with certain subsets of regulatory B-cells (Bregs). The latter cells have been reported to negatively regulate immune cell responses, mostly by provision of IL 10. The purpose of the current study was to identify and delineate Breg properties of CLL cells. B-cells and T-cells were obtained from the peripheral blood of untreated CLL patients diagnosed according to the 2008 Guidelines of the International Workshop on Chronic Lymphocytic Leukemia. Co-culture assays were used to examine the ability of CLL cells to suppress autologous T-cell immune responses. IL-10 potency of CLL cells was assessed following stimulation with activators of the toll-like receptor 9 (TLR9) or CD40 and was correlated with the inhibitory activity of the cells. TLR9-activated CLL cells were found to increase the frequency of CD4+CD25hiFOXp3+ regulatory T-cells (Tregs) and to inhibit autologous CD4+ T-cell proliferation. This signaling cascade proved to control IL 10 generation in CLL cells, which in turn promoted the inhibition of T-cell proliferation by CLL cells. However, CD40 activation of CLL cells, while exhibiting a similar ability to augment Treg frequency, did not either affect IL 10 generation or T-cell proliferation. In conclusion, CLL cells demonstrate a unique clonal quality of adopting Breg properties which promote modulation of T cell characteristics. TLR9 appears to be a potent activator of regulatory abilities in CLL cells, possibly contributing to preferential immune escape of TLR9-responsive cells. PMID- 29450642 TI - Risk factors of non-specific spinal pain in childhood. AB - PURPOSE: Non-specific spinal pain can occur at all ages and current evidence suggests that pediatric non-specific spinal pain is predictive for adult spinal conditions. A 5-year long, prospective cohort study was conducted to identify the lifestyle and environmental factors leading to non-specific spinal pain in childhood. MATERIALS AND METHODS: Data were collected from school children aged 7 16 years, who were randomly selected from three different geographic regions in Hungary. The risk factors were measured with a newly developed patient-reported questionnaire (PRQ). The quality of the instrument was assessed by the reliability with the test-retest method. Test (N = 952) and validity (N = 897) datasets were randomly formed. Risk factors were identified with uni- and multivariate logistic regression models and the predictive performance of the final model was evaluated using the receiver operating characteristic (ROC) method. RESULTS: The final model was built up by seven risk factors for spinal pain for days; age > 12 years, learning or watching TV for more than 2 h/day, uncomfortable school-desk, sleeping problems, general discomfort and positive familiar medical history (chi2 = 101.07; df = 8; p < 0.001). The probabilistic performance was confirmed with ROC analysis on the test and validation cohorts (AUC = 0.76; 0.71). A simplified risk scoring system showed increasing possibility for non-specific spinal pain depending on the number of the identified risk factors (chi2 = 65.0; df = 4; p < 0.001). CONCLUSION: Seven significant risk factors of non-specific spinal pain in childhood were identified using the new, easy to use and reliable PRQ which makes it possible to stratify the children according to their individual risk.

PMID- 29450643 TI - Variants in FIX propeptide associated with vitamin K antagonist hypersensitivity: functional analysis and additional data confirming the common founder mutations. AB - One of the most common and unwanted side effects during oral anticoagulant therapy (OAT) is bleeding complications. In rare cases, vitamin K antagonist (VKA)-related bleeding events are associated with mutations affecting the F9 propeptide at amino acid position 37 due to a substitution of alanine to either valine or threonine. Based on our actual cohort of 18 patients, we update the knowledge on this rare phenotype and its origin. A founder mutation for both variants was reconfirmed by haplotype analysis of intronic and extragenic short tandem repeat (STR) polymorphisms with a higher prevalence in Switzerland than in other regions of Europe. Screening of healthy individuals for the presence of these F9 gene mutations did not identify any of these variants, thus proving the rare occurrence of this genotype. Furthermore, both variants were expressed in vitro and warfarin dose responses were studied. Our warfarin dose response analysis confirmed higher sensitivity of both variants to warfarin with the effect being more apparent for Ala37Thr. Thus, although F9 propeptide mutation associated hypersensitivity to VKA is a rare phenomenon, awareness towards this bleeding phenotype is important to identify patients at risk. PMID- 29450644 TI - PI3K/Akt inhibitor LY294002 potentiates homoharringtonine antimyeloma activity in myeloma cells adhered to stromal cells and in SCID mouse xenograft. AB - Homoharringtonine (HHT) is a known anti-leukemia drug that inhibits multiple myeloma (MM) cells both in vitro and in vivo. Our prior study demonstrated that the potency of HHT in MM cells was compromised significantly when myeloma cells were co-cultured with BM stromal cells. This study aimed to investigate whether PI3K/Akt inhibitor LY294002 could potentiate the antimyeloma activity of HHT against MM cells adhered to BM stromal cells and in vivo xenograft models. A co culture system composed of MM cells and human stromal cells was employed to mimic MM cells in bone marrow niche. The inhibitory and pro-apoptotic effect of HHT and LY294002 was determined by CCK-8 assay or flow cytometry. Expression of PI3K/Akt signaling molecules and anti-apoptotic protein myeloid cell leukemia-1 (Mcl-1) was assessed by western blot analysis and/or reverse transcription real-time quantitative PCR (RT-qPCR). MM xenografts were used to evaluate antitumor effect of combined therapy with HHT and LY294002. Adhesion to BM stromal cells rendered MM cells resistant to HHT whereas silencing Mcl-1 partly reversed the resistance. LY294002 induced apoptosis in MM cells and potentiated the antimyeloma effects of HHT by inhibiting the PI3K/Akt signal pathway which was abnormally activated during adhesion. LY294002 also enhanced the antimyeloma effect of HHT in in vivo xenograft models. These findings suggest that activation of PI3K/Akt signal pathway was responsible for the resistance to HHT in MM cells adhered to stromal cells. LY294002 can potentiate the antimyeloma activity of HHT both in vitro and in vivo, which may represent a new clinical treatment in MM. PMID- 29450645 TI - Brain c-fos expression patterns induced by emotional stressors differing in nature and intensity. AB - Regardless of its particular nature, emotional stressors appear to elicit a widespread and roughly similar brain activation pattern as evaluated by c-fos expression. However, their behavioral and physiological consequences may strongly differ. Here we addressed in adult male rats the contribution of the intensity and the particular nature of stressors by comparing, in a set of brain areas, the number of c-fos expressing neurons in response to open-field, cat odor or immobilization on boards (IMO). These are qualitatively different stressors that are known to differ in terms of intensity, as evaluated by biological markers. In the present study, plasma levels of the adrenocorticotropic hormone (ACTH) demonstrated that intensity increases in the following order: open-field, cat odor and IMO. Four different c-fos activation patterns emerged among all areas studied: (i) positive relationship with intensity (posterior-dorsal medial amygdala, dorsomedial hypothalamus, lateral septum ventral and paraventricular nucleus of the hypothalamus), (ii) negative relationship with intensity (cingulate cortex 1, posterior insular cortex, dorsal striatum, nucleus accumbens and some subdivisions of the hippocampal formation); (iii) activation not dependent on the intensity of the stressor (prelimbic and infralimbic cortex and lateral and basolateral amygdala); and (iv) activation specifically associated with cat odor (ventromedial amygdala and ventromedial hypothalamus). Histone 3 phosphorylation at serine 10, another neuronal activation marker, corroborated c fos results. Summarizing, deepest analysis of the brain activation pattern elicit by emotional stressor indicated that, in spite of activating similar areas, each stressor possess their own brain activation signature, mediated mainly by qualitative aspects but also by intensity.

AB - Amyloid-beta (Abeta) is a peptide deposited in the brain parenchyma in Alzheimer's disease and in cerebral blood vessels, causing cerebral amyloid angiopathy (CAA). Abeta pathology is transmissible experimentally in animals and through medical procedures in humans, such as contaminated growth hormone or dura mater transplantation in the context of iatrogenic prion disease. Here, we present four patients who underwent neurosurgical procedures during childhood or teenage years and presented with intracerebral haemorrhage approximately three decades later, caused by severe CAA. None of these patients carried pathogenic mutations associated with early Abeta pathology development. In addition, we identified in the literature four patients with a history of neurosurgical intervention and subsequent development of CAA. These findings raise the possibility that Abeta pathology may be transmissible, as prion disease is, through neurosurgical procedures.

PMID- 29450649 TI - Plant species occurrence patterns in Eurasian grasslands reflect adaptation to nutrient ratios. AB - Previous studies of Eurasian grasslands have suggested that nutrient ratios, rather than absolute nutrient availabilities and associated productivity, may be driving plant species richness patterns. However, the underlying assumption that species occupy distinct niches along nutrient ratio gradients remains to be tested. We analysed plant community composition and nutrient status of 644 Eurasian wet grassland plots. The importance of nutrient ratios driving variation in species composition was analysed using ordination methods (DCA and CCA). Subsequently, we assessed the niche position and width along the most important nutrient ratio gradient [N:P] for each species. We found that the N:P ratio explained part of the variation in species composition independent from conventional explanatory variables. The N:P ratio explained less variation than soil moisture or pH, but more than productivity or the availability of N and P separately, highlighting its importance for grassland species composition. Species occupied distinct niches along the N:P gradient, and species' niche widths decreased toward extreme nutrient limitation. After correcting for niche position, there was no overall difference in niche width between endangered and non-endangered species. Surprisingly, endangered species with niche optima at the extreme P-limited end of the gradient had broader niches than their non endangered counterparts. As species occupied distinct niches along a nutrient ratio gradient, future grassland conservation efforts may benefit from targeting changes in nutrient ratios, i.e. the balance between N and P, rather than only focussing on a general reduction in nutrient availability. However, what management interventions can be used for this purpose remains unclear. PMID- 29450651 TI - Who will remain tremor dominant? The possible role of cognitive reserve in the time course of two common Parkinson's disease motor subtypes. AB - In a prospective 5-year study among Parkinson's disease (PD) tremor-dominant (TD) patients, we investigated who will remain TD and who will later convert into the postural instability gait difficulty (PIGD) phenotype. At follow-up, 38% were still considered TD. At baseline the TD non-convertors had more years of education and better cognitive function than the convertors and significantly smaller deterioration in gait, balance, cognitive function and other non-motor symptoms. These results highlight the potential role of cognition in protecting against the development of PIGD symptoms. PMID- 29450653 TI - Microdialysis as a useful tool to detect cerebral metabolic crises. PMID- 29450652 TI - Enhanced Tumor Diagnostic and Therapeutic Effect of Mesoporous Silica Nanoparticle-Mediated Pre-targeted Strategy. AB - PURPOSE: Improving the targeting efficiency of imaging agents or anticancer drugs has become essential in the current primary mission to enhance the diagnostic or therapeutic effects. To improve the tumor diagnosis and therapy effect, a promising drug-delivery and targeting strategy was established based on the bioorthogonal chemistry. METHOD: The delivery system was composed of the pre targeting carrier Biotin-MSNs-DBCO nanoparticles and the azido cargoes. The fluorescence probe 1-(3-azidopropyl) fluorescein (FITC-N3) and ruthenium N heterocyclic carbene complex N3-S-S-NHC-Ru were synthesized and served as the tumor imaging and therapy probes, respectively. The cell imaging and viability was investigated by the Biotin-MSNs-DBCO pre-targeted for 4 h in colonic carcinoma (HeLa) cells. RESULTS: For the tumor cell imaging, Biotin-MSNs-DBCO could react with FITC-N3 rapidly and completely in 20 min with 93% yields. The fluorescence intensity of tumor cells was obviously increased by the Biotin-MSNs DBCO pre-targeted. The cytotoxicity of the ruthenium complex N3-S-S-NHC-Ru was significantly improved appropriately three times with the IC50 (half inhibitory concentration) value of 6.68 +/- 1.29 MUM and enhancement of the mitochondrial dysfunction. CONCLUSIONS: The pre-targeting nanoparticle Biotin-MSNs-DBCO could selectively capture the azido compounds in tumor cells, which provided a site specific target for the cargoes and then resulted in an enhancement of diagnostic or therapeutic effects. PMID- 29450650 TI - Access to the CNS: Biomarker Strategies for Dopaminergic Treatments. AB - Despite substantial research carried out over the last decades, it remains difficult to understand the wide range of pharmacological effects of dopaminergic agents. The dopaminergic system is involved in several neurological disorders, such as Parkinson's disease and schizophrenia. This complex system features multiple pathways implicated in emotion and cognition, psychomotor functions and endocrine control through activation of G protein-coupled dopamine receptors. This review focuses on the system-wide effects of dopaminergic agents on the multiple biochemical and endocrine pathways, in particular the biomarkers (i.e., indicators of a pharmacological process) that reflect these effects. Dopaminergic treatments developed over the last decades were found to be associated with numerous biochemical pathways in the brain, including the norepinephrine and the kynurenine pathway. Additionally, they have shown to affect peripheral systems, for example the hypothalamus-pituitary-adrenal (HPA) axis. Dopaminergic agents thus have a complex and broad pharmacological profile, rendering drug development challenging. Considering the complex system-wide pharmacological profile of dopaminergic agents, this review underlines the needs for systems pharmacology studies that include: i) proteomics and metabolomics analysis; ii) longitudinal data evaluation and mathematical modeling; iii) pharmacokinetics-based interpretation of drug effects; iv) simultaneous biomarker evaluation in the brain, the cerebrospinal fluid (CSF) and plasma; and v) specific attention to condition-dependent (e.g., disease) pharmacology. Such approach is considered essential to increase our understanding of central nervous system (CNS) drug effects and substantially improve CNS drug development.

AB - BACKGROUND: The advantages of 5-aminolevulinacid (5-ALA)-induced fluorescence guided surgery in meningiomas are increasingly discussed. In this context, despite detectable tumor tissue in histopathologial analyses, no fluorescence was shown at the dura tail using the standard operating microscope. Thus, 5-ALA metabolism in this surgically important site remains unknown but needs to be elucidated when further evaluating indications of fluorescence-guided surgery in meningiomas. METHOD: We here present the spatially resolved identification of protoporphyrin IX (PpIX) in sphenoid ridge meningioma cryosections from a patient who underwent fluorescence-guided microsurgery using molecular imaging analysis by matrix-assisted laser desorption/ionization tandem mass spectrometry (MALDI MS/MS). RESULTS: Despite a strong fluorescence of the main tumor, no fluorescence could be detected at the dura tail using the standard operating microscope (blue light, 405 nm). However, histopathological analyses clearly showed meningioma tissue. Remarkably, MALDI-MS/MS analysis revealed PpIX formation also at the non fluorescing dura tail. However, no PpIX was detected in the tumor free dura mater. CONCLUSION: MALDI-MS/MS visualized a selective accumulation of PpIX within the tumor tissue including the dura tail. Thus, absence of fluorescence in the dura tail as visualized by the operating microscope is not caused by the lack of PpIX formation. PMID- 29450656 TI - Laparoscopic subtotal gastrectomy in morbid obese patients: a valid option to laparoscopic gastric bypass in particular circumstances (prospective study). AB - BACKGROUND: Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) without resection of the distal stomach is largely performed over the world for morbid obesity. Potential risk of gastric remnant carcinoma development has been suggested. PURPOSE: To present the results obtained after LRYGB with resection of distal stomach. METHOD: This prospective study includes 400 consecutive patients. The mean body weight was 105.9 +/- 16.8 Kg (range 83-145 kg), and body mass index (BMI) was 38.5 +/- 4.4 kg/m2 (32.9-50.3). Postoperative morbid-mortality and follow-up were analyzed. RESULTS: Operative time was 128.5 +/- 18.7 min, hospital discharge occurred at 3rd postoperative day, postoperative complications occurred in 9.25%, early surgical complications were observed in 3% and medical complications 4%, late surgical complications occurred 2.25%, no mortality was observed. At 1 year follow-up, BMI was 25.3 +/- 2.7 kg/m2 with % of weight loss (%WL) of 84.6 + 19.1%. At five years follow-up very similar values were observed. CONCLUSION: The results obtained after LRYGB with resection of distal stomach are similar to results published after non resection LRYGB regarding early and late results and can be indicated in high risk areas of gastric carcinoma. PMID- 29450655 TI - Transcription factors network in root endosymbiosis establishment and development. AB - Root endosymbioses are mutualistic interactions between plants and the soil microorganisms (Fungus, Frankia or Rhizobium) that lead to the formation of nitrogen-fixing root nodules and/or arbuscular mycorrhiza. These interactions enable many species to survive in different marginal lands to overcome the nitrogen-and/or phosphorus deficient environment and can potentially reduce the chemical fertilizers used in agriculture which gives them an economic, social and environmental importance. The formation and the development of these structures require the mediation of specific gene products among which the transcription factors play a key role. Three of these transcription factors, viz., CYCLOPS, NSP1 and NSP2 are well conserved between actinorhizal, legume, non-legume and mycorrhizal symbioses. They interact with DELLA proteins to induce the expression of NIN in nitrogen fixing symbiosis or RAM1 in mycorrhizal symbiosis. Recently, the small non coding RNA including micro RNAs (miRNAs) have emerged as major regulators of root endosymbioses. Among them, miRNA171 targets NSP2, a TF conserved in actinorhizal, legume, non-legume and mycorrhizal symbioses. This review will also focus on the recent advances carried out on the biological function of others transcription factors during the root pre-infection/pre contact, infection or colonization. Their role in nodule formation and AM development will also be described. PMID- 29450657 TI - In silico identification of small molecules as novel LXR agonists for the treatment of cardiovascular disease and cancer. AB - Liver X receptor (LXR), a member of the nuclear receptor superfamily, mainly serves as a reverse cholesterol transporter in lipid metabolism. It has been demonstrated that LXR is a promising target for the treatment of cardiovascular diseases. LXR is also involved in cancer metabolism, glucose homeostasis, immunity, and various physiological processes. The antitumor function of LXR has become of great interest to researchers in recent years. However, while it is believed that activating LXR with small molecules could be a promising approach to cancer treatment, effective drugs that target LXR are yet to be reported. To find compounds that are potentially capable of activating LXR, we utilized a high throughput screening method to search the MolMall database for suitable compounds. Seven candidates with lower GB/SA Hawkins scores than the reference ligand T0901317 were identified. Based on the results of molecular dynamics (MD) simulations, binding free energy analysis, and an analysis of the agonism mechanism, ZINC90512020 and ZINC3845032 were predicted to have high affinities for LXR and high relative stabilization, and were therefore selected as potential LXR agonists. Both of these compounds will undergo further development with a view to utilizing them for the treatment of LXR-related cardiovascular diseases or cancers. PMID- 29450659 TI - Social Factors in the Development of Chronic Rhinosinusitis: a Systematic Review. AB - PURPOSE OF REVIEW: In an era where prevention is paramount, understanding social factors for chronic rhinosinusitis (CRS) may facilitate preventive interventions that mitigate risk factors associated with the initiation or progression of the disease. RECENT FINDINGS: Both passive and active smoking are clearly and unequivocally associated with both the incidence and the severity of rhinosinusitis, while there an increasing body of evidence linking social deprivation and low socioeconomic status with rhinosinusitis and its complications. However, overall, only a handful of studies were longitudinal, while the available studies suffer from lack of standardized definitions of rhinosinusitis. In this systematic review, we assessed the available evidence linking CRS with social factors, such as socioeconomic status and class, educational status, family status, living and working location and conditions, and use of toxins or recreational drugs as well as exercise and diet. Thirty studies from 1995 onwards fulfilled our inclusion criteria and were used for this review. Social deprivation and low socioeconomic level seem to be directly associated with rhinosinusitis, as there are pollutants in living or working environment. A clear and direct association between smoking (both active and passive) and rhinosinusitis was also shown. However, the link between rhinosinusitis and education level, and exercise and diet, if any, seems to be more complex. PMID- 29450658 TI - Modified Allergens for Immunotherapy. AB - PURPOSE OF REVIEW: During the past few decades, modified allergens have been developed for use in allergen-specific immunotherapy (AIT) with the aim to improve efficacy and reduce adverse effects. This review aims to provide an overview of the different types of modified allergens, their mechanism of action and their potential for improving AIT. RECENT FINDINGS: In-depth research in the field of allergen modifications as well as the advance of recombinant DNA technology have paved the way for improved diagnosis and research on human allergic diseases. A wide range of structurally modified allergens has been generated including allergen peptides, chemically altered allergoids, adjuvant coupled allergens, and nanoparticle-based allergy vaccines. These modified allergens show promise for the development of AIT regimens with improved safety and long-term efficacy. Certain modifications ensure reduced IgE reactivity and retained T cell reactivity, which facilities induction of immune tolerance to the allergen. To date, multiple clinical trials have been performed using modified allergens. Promising results were obtained for the modified cat, grass and birch pollen, and house dust mite allergens. The use of modified allergens holds promise for improving AIT efficacy and safety. There is however a need for larger clinical studies to reliably assess the added benefit for the patient of using modified allergens for AIT. PMID- 29450660 TI - Protein nutritional value, polyphenols and antioxidant properties of corn fermented with Agaricus brasiliensis and Agaricus bisporus. AB - Solid-state fermentation (SSF) with Agaricus brasiliensis and Agaricus bisporus on corn was carried out. The results showed that SSF with the two fungi made up the deficiency of tryptophan in corn and improved the protein nutritional value of corn. The conjugated polyphenols contents in fermented corn decreased and free polyphenols (FPP) contents increased. FPP contents in corn fermented with the two fungi reached respectively 25 and 88 times of control, total polyohenols contents reached respectively 1.4 and 3.3 times of control. The antioxidant properties (i.e. 1,1-diphenyl-2-picrylhydrazyl radical scavenging capacity, reducing power, ferrous ion chelating ability and superoxide anion radical scavenging ability) of fermented corn were improved significantly. SSF with A. bisporus was more favorable to the enhancement in protein nutritional value and antioxidant properties of corn than that of A. brasiliensis. The results indicated that SSF with the two fungi could upgrade the protein nutritional value, FPP content and antioxidant properties of corn. PMID- 29450661 TI - Monitoring water quality in a hypereutrophic reservoir using Landsat ETM+ and OLI sensors: how transferable are the water quality algorithms? AB - The launch of the Landsat 8 in February 2013 extended the life of the Landsat program to over 40 years, increasing the value of using Landsat to monitor long term changes in the water quality of small lakes and reservoirs, particularly in poorly monitored freshwater systems. Landsat-based water quality hindcasting often incorporate several Landsat sensors in an effort to increase the temporal range of observations; yet the transferability of water quality algorithms across sensors remains poorly examined. In this study, several empirical algorithms were developed to quantify chlorophyll-a, total suspended matter (TSM), and Secchi disk depth (SDD) from surface reflectance measured by Landsat 7 ETM+ and Landsat 8 OLI sensors. Sensor-specific multiple linear regression models were developed by correlating in situ water quality measurements collected from a semi-arid eutrophic reservoir with band ratios from Landsat ETM+ and OLI sensors, along with ancillary data (water temperature and seasonality) representing ecological patterns in algae growth. Overall, ETM+-based models outperformed (adjusted R2 chlorophyll-a = 0.70, TSM = 0.81, SDD = 0.81) their OLI counterparts (adjusted R2 chlorophyll-a = 0.50, TSM = 0.58, SDD = 0.63). Inter-sensor differences were most apparent for algorithms utilizing the Blue spectral band. The inclusion of water temperature and seasonality improved the power of TSM and SDD models. PMID- 29450663 TI - Children's Doctor Games and Nudity at Danish Childcare Institutions. AB - This article presents the first Danish study of the acceptance of children's nudity and sexuality at Danish childcare institutions. The study revealed an important cultural shift in the attitude toward children's nudity and sexual games, the so-called doctor games. Although these were quite accepted at Danish childcare institutions until the beginning of this century, the study showed that new, pervasive regulations had been established to control the child's body and its sexuality. A new discourse revealed that fear of child sexual abuse, in particular, had influenced views of children's sexual games and nudity and that, at times, the child itself was viewed as a potential threat to other children. This marks a new development in Denmark, internationally known for its broadmindedness, and this article discusses the background to this cultural shift in the institutions, and possible implications for the children. PMID- 29450662 TI - Preconception Counseling for Adolescents and Young Adults with Diabetes: a Literature Review of the Past 10 Years. AB - PURPOSE OF REVIEW: Women with diabetes who have unplanned pregnancies and uncontrolled blood sugars are at a higher risk for maternal and fetal morbidities and mortalities. Preconception counseling (PC) has been shown to decrease the risks and improve health outcomes. From 2009 to 2017, the American Diabetes Association has recommended that preconception counseling be given at each clinic visit for all women with diabetes of childbearing age starting at puberty (prior to sexual debut). RECENT FINDINGS: This article reports both national and international progress in PC efforts for adolescents and young adults (12-34 years) with diabetes over the past decade. Twenty-eight publications were identified and included in this article (11 were research, 12 clinical guidelines, and 5 reviews). Despite recommendations to start PC at puberty, only four studies had interventions that targeted the adolescent and young adult age group. Three of them were associated with the same PC awareness program. Positive outcomes were reported in all of these studies. Greater family vigilance was observed in a long-term follow-up of a cohort of women who received PC as teens. Adolescents should receive awareness PC. More early PC interventions and cohort follow-up studies are needed among adolescents and young adults, using technology that appeals to this age group. Programs should be expanded to include other populations like males with diabetes and females from other cultures and religions that would require program modification. PMID- 29450664 TI - Radiographic study of mandibular third molars: evaluation of the position and root anatomy in Brazilian population. AB - OBJECTIVES: The root anatomy and position of mandibular third molars are important factors in assessing the level of difficulty of surgical removal procedures. In this light, this study aims to identify the most frequent position and the root anatomy of mandibular third molars. METHODS: The study sample comprised 1205 mandibular third molars from 710 panoramic radiographs evaluated. Regarding the position, all of them were based on Pell and Gregory's and Winter's classifications. The root anatomy was classified according to the type and number of roots, as well as the presence of laceration, fusion, or divergence. Gender and the quadrant were also considered. Following an interexaminer analysis, a statistical analysis was performed using the Kappa test. RESULTS: The results showed that the IA (40.3%) and mesioangular (53.8%) position was predominant in mandibular third molars. Regarding the anatomy, the most common were two roots (98.3%), of the conical simple type (88.9%), with absence of laceration (89.2%), divergence (84%), and fusion (80%). CONCLUSION: The present study showed that the most prevalent mandibular third molar type in Brazilian patients was the IA and mesioangular position, with simple root anatomy. The result of this study can assist oral surgeons to better plan and assess the level of difficulty of surgical removal procedures. PMID- 29450665 TI - Biochemical pathways and enhanced degradation of di-n-octyl phthalate (DOP) in sequencing batch reactor (SBR) by Arthrobacter sp. SLG-4 and Rhodococcus sp. SLG 6 isolated from activated sludge. AB - Two bacterial strains designated as Arthrobacter sp. SLG-4 and Rhodococcus sp. SLG-6, capable of utilizing di-n-octyl phthalate (DOP) as sole source of carbon and energy, were isolated from activated sludge. The analysis of DOP degradation intermediates indicated Arthrobacter sp. SLG-4 could completely degrade DOP. Whereas DOP could not be mineralized by Rhodococcus sp. SLG-6 and the final metabolic product was phthalic acid (PA). The proposed DOP degradation pathway by Arthrobacter sp. SLG-4 was that strain SLG-4 initially transformed DOP to PA via de-esterification pathway, and then PA was metabolized to protocatechuate acid and eventually converted to tricarboxylic acid (TCA) cycle through meta-cleavage pathway. Accordingly, Phthalate 3,4-dioxygenase genes (phtA) responsible for PA degradation were successfully detected in Arthrobacter sp. SLG-4 by real-time quantitative PCR (q-PCR). q-PCR analysis demonstrated that the quantity of phthalate 3,4-dioxygenase was positively correlated to DOP degradation in SBRs. Bioaugmentation by inoculating DOP-degrading bacteria effectively shortened the start-up of SBRs and significantly enhanced DOP degradation in bioreactors. More than 91% of DOP (500 mg L-1) was removed in SBR bioaugmented with bacterial consortium, which was double of the control SBR. This study suggests bioaugmentation is an effective and feasible technique for DOP bioremediation in practical engineering. PMID- 29450667 TI - A risk prediction model to allow personalized screening for cervical cancer. AB - IMPORTANCE: Cervical cancer screening guidelines are in evolution. Current guidelines do not differentiate recommendations based on individual patient risk. OBJECTIVE: To derive and validate a tool for predicting individualized probability of cervical intraepithelial neoplasia grade 2 or higher (CIN2+) at a single time point, based on demographic factors and medical history. DESIGN: The study design consisted of an observational cohort with hierarchical generalized linear regression modeling. SETTING: The study was conducted in a setting of 33 primary care practices from 2004 to 2010. PARTICIPANTS: The participants of the study were women aged >= 30 years. MAIN OUTCOME AND MEASURES: CIN2+ was the main outcome on biopsy, and the following predictors were included: age, race, marital status, insurance type, smoking history, median income based on zip code, prior human papilloma virus (HPV) results. RESULTS: The final dataset included 99,319 women. Of these, 745 (0.75%) had CIN2+. The multivariable model had a C-statistic of 0.81. All factors but race were independently associated with CIN2+. The model categorized women as having below-average CIN2+ risk (0.15% predicted vs. 0.12% observed risk), average CIN2+ risk (0.42% predicted vs. 0.36% observed), and above-average CIN2+ risk (1.76% predicted vs. 1.85% observed). Before screening, women at below-average risk had a risk of CIN2+ well below that of women with ASCUS and HPV negative (0.12 vs. 0.20%). CONCLUSIONS AND RELEVANCE: A multivariable model using data from the electronic health record was able to stratify women across a 50-fold gradient of risk for CIN2+. After further validation, use of a similar model could enable more targeted cervical cancer screening. PMID- 29450666 TI - Recent advances in hyaluronic acid based therapy for osteoarthritis. AB - Osteoarthritis is a debilitating disease that has increased in prevalence across the world due to the aging population. Currently, physicians use a plethora of treatment strategies to try and slow down the progression of the disease, but none have been shown to ubiquitously treat and cure the disease. One of the strategies uses the high molecular weight molecule hyaluronic acid as either an injectable or oral supplement for treatment. Hyaluronic acid (HA) is a relatively new treatment that has shown varied results through several clinical trials. It can be used as a scaffold for engineering new treatments and several new preparations have just been added to the market. A comprehensive search was conducted through several search databases according our inclusion and exclusion criteria. This review included 44 prospective clinical trial investigating the feasibility and efficacy of HA injection for knee, hip, and ankle osteoarthritis. This review will take a closer look at hyaluronic acid and its properties, as well clinical effectiveness and future options. PMID- 29450668 TI - Genetic variation and selection of MHC class I loci differ in two congeneric frogs. AB - Major histocompatibility complex (MHC) genes encode proteins in the acquired immune response pathway that often show distinctive selection-driven patterns in wild vertebrate populations. We examined genetic variation and signatures of selection in the MHC class I alpha 1 (A1)- and alpha 2 (A2)-domain encoding exons of two frog congeners [Agalychnis callidryas (n = 20) and A. lemur (n = 20)] from a single locality in Panama. We also investigated how historical demographic processes may have impacted MHC genetic diversity by analyzing a neutral mitochondrial marker. We found that both MHC domains were highly variable in both species, with both species likely expressing three loci. Our analyses revealed different signatures of selection between the two species, most notably that the A. callidryas A2 domain had experienced positive selection while the A2 domain of A. lemur had not. Diversifying selection acted on the same number of A1 and A2 allelic lineages, but on a higher percentage of A1 sites compared to A2 sites. Neutrality tests of mitochondrial haplotypes predominately indicated that the two species were at genetic equilibrium when the samples were collected. In addition, two historical tests of demography indicated both species have had relatively stable population sizes over the past 100,000 years; thus large population size changes are unlikely to have greatly influenced MHC diversity in either species during this time period. In conclusion, our results suggest that the impact of selection on MHC diversity varied between these two closely related species, likely due to a combination of distinct ecological conditions and past pathogenic pressures. PMID- 29450669 TI - Association of TERT-CLPTM1L and 8q24 Common Genetic Variants with Gallbladder Cancer Susceptibility and Prognosis in North Indian Population. AB - Gallbladder carcinoma (GBC) is one of the common malignancy of the biliary tract. Several genome wide and candidate gene studies have reported associations between multiple cancer types and single-nucleotide polymorphisms on 5p15.33 and 8q24.21 loci. However, predisposition potential of these genetic variants has not been assessed in GBC. We performed the present study to assess the potential of five polymorphisms on 5p15.33 and one on 8q24.21 locus in GBC risk and treatment response in patients undergoing chemoradiotherapy. We extracted genomic DNA from peripheral blood and genotyped selected SNPs using TaqMan allelic discrimination assays in 523 GBC cases and 274 controls from the north-Indian population. Statistical tests were performed to assess the association of selected common genetic variants with gallbladder cancer susceptibility and prognosis. Binary logistic regression analysis showed significant association of TERT rs2736100C > A [OR(CI) = 0.690(0.515-0.924), p value = 0.013], CLPTM1L rs401681C > T [OR(CI) = 0.586(0.405-0.847), p value = 0.004], and CASC8 rs6983267G > T [OR(CI) = 1.629(1.215-2.186), p value = 0.001] with GBC risk. Further, using multivariate logistic regression, we observed that haplotype CLPTM1L Crs401681Crs31489 TERT Trs2853676Ars2736100 MIR4457 Grs4635969 [OR(CI) = 7.52 (1.79-31.52), p value = 0.0064] is significantly associated with poor treatment response. In survival analysis, Kaplan-Meier survival curves showed significantly poor survival and COX regression suggested significantly higher hazard ratio in TT genotype carriers of CASC8 rs6983267 [OR(CI) = 4.28(1. 07-17.10), p value = 0.040] as compared to major allele and heterozygous (GG+GT) genotypes in metastatic GBC cases. The study revealed that 5p15.33 and 8q24.21 genetic variants significantly influence GBC risk and treatment response in north-Indian population. PMID- 29450670 TI - Acetylsalicylic acid enhance tolerance of Phaseolus vulgaris L. to chilling stress, improving photosynthesis, antioxidants and expression of cold stress responsive genes. AB - BACKGROUND: High and low temperatures constitute the most damaging type of abiotic stress and limit the survival, and productivity of plants. The present study aimed to evaluate the role of exogenous applications of acetylsalicylic acid (ASA) in reducing the deleterious effects of cold stress. Phaseolus vulgaris L. seedlings were treated with foliar-sprayed ASA at concentrations of 0-3 mM and then subjected to chilling stress at 4 degrees C for 2 or 4 days. RESULTS: Growth, photosynthesis, biochemical alterations, oxidative damage and antioxidant enzyme activities as well as the expression of cold-responsive genes (CBF3 COR47), were monitored during the experiment. ASA applications substantially improved several growth and photosynthetic parameters, including shoot biomass, dry weight, and photosynthetic pigments, of P. vulgaris seedlings exposed to different durations of chilling stresses. The ASA foliar spray treatments significantly (p < 0.05) rescued the growth and photosynthetic pigments of P. vulgaris seedlings under different chilling stresses. The total soluble sugars markedly increased during 0-4 days of chilling stress following ASA foliar spraying. The exogenous application of ASA significantly (p < 0.05) increased the accumulation of proline in P. vulgaris seedlings under chilling stress. At the gene expression level, ASA significantly (p < 0.05) upregulated the cold responsive genes CBF3 and COR47. CONCLUSIONS: As a result, we speculate that, the application of exogenous ASA alleviated the adverse effects of chilling stress on all measured parameters, and 1 and 2 mM ASA exhibited the greatest effects.

PMID- 29450671 TI - Short-term treatment with metformin reduces hepatic lipid accumulation but induces liver inflammation in obese mice. AB - The study aimed to evaluate the metabolic and inflammatory effects of short-term treatments (10 days) with metformin (MET) on the NAFLD caused by a high-fat diet (HFD) in C57BL/6 mice. After the treatment, histological liver slices were obtained, hepatocytes and macrophages were extracted and cultured with phosphate buffered saline, LPS (2.5 ug/mL) and MET (1 uM) for 24 h. Cytokine levels were determined by ELISA. NAFLD caused by the HFD was partially reduced by MET. The lipid accumulation induced by the HFD was not associated with liver inflammation; however, MET seemed to promote pro-inflammatory effects in liver, since it increased hepatic concentration of IL-1beta, TNF-alpha, IL-6, MCP-1 and IFN gamma. Similarly, MET increased the concentration of IL-1beta, IL-6 in hepatocyte cultures. However, in macrophages culture, MET lowered levels of IL-1beta, IL-6 and TNF-alpha stimulated by LPS. Overall, MET reduced liver NAFLD but promoted hepatocyte increase in pro-inflammatory cytokines, thus, leading to liver inflammation. PMID- 29450673 TI - Recent advances in enhanced enzyme activity, thermostability and secretion by N glycosylation regulation in yeast. AB - Yeast has been increasingly used as a host for the expression of enzymes. Compared to other expression systems, the yeast expression system has many advantages including its suitability for large-scale fermentation and its ability to modify enzymes. When expressed in yeast, many recombinant enzymes are N glycosylated, and this may play an important role in their activity, thermostability and secretion. Although the mechanism underlying this process is not clear, the regulation of N-glycosylation by introducing or eliminating N glycosylation at specific sites has developed into an important strategy for improving the production or catalytic properties of recombinant enzymes. In this review, we summarize the recent advances in understanding the effects of N glycosylation on the expression and characteristics of recombinant enzymes, and discuss novel strategies for regulating N-glycosylation in yeast. We hope that this review will help improve the understanding of the expression and the catalytic properties of N-glycosylated proteins. PMID- 29450675 TI - Lipid-lowering drugs, dyslipidemia, and breast cancer risk in a Medicare population. AB - PURPOSE: We sought to disentangle the effects of statins and other lipid-lowering drugs and the underlying dyslipidemia for which they are prescribed on breast cancer risk. METHODS: We conducted a case-control study within the linked Surveillance, Epidemiology, and End results (SEER)-Medicare data. Cases were women with invasive breast cancer aged 66 + years (N = 30,004) identified by SEER registries (years 2007-2011). Controls were women (N = 198,969) identified from a 5% random sample of Medicare recipients alive and breast cancer free in year of selection. Participants had a minimum of 13 months of Part A, Part B non-health maintenance organization Medicare and Part D Medicare coverage at least 13 months preceding cancer diagnosis/selection. Exposures were assessed until 12 months before diagnosis/control selection. Odds ratios (OR) and 99.9% confidence intervals (CI) were estimated using adjusted unconditional and multinomial logistic regression. RESULTS: ORs of invasive breast cancer associated with dyslipidemia, statins, and non-statin lipid-lowering drugs were 0.86 (99.9% CI 0.81-0.90), 1.07 (99.9% CI 1.03-1.13) and 1.03 (99.9% CI 0.95-1.11), respectively. Risk reductions with dyslipidemia were slightly greater when untreated than treated and did not vary much by time between dyslipidemia and breast cancer diagnosis. Whether treated or untreated, dyslipidemia was associated with greater reductions in risk for later stage than earlier stage breast cancer (p-heterogeneity < 0.0001). CONCLUSIONS: Lipid-lowering drugs did not account for the lower breast cancer risk associated with dyslipidemia. Our data do not support using statins or other lipid-lowering drugs to prevent breast cancer. PMID- 29450674 TI - Risk assessment of pesticides in estuaries: a review addressing the persistence of an old problem in complex environments. AB - Estuaries, coastal lagoons and other transition ecosystems tend to become the ultimate reservoirs of pollutants transported by continental runoff, among which pesticides constitute the class of most concern. High amounts of dissolved and particulated organic matter greatly contribute to the accumulation of pesticides that eventually become trapped in sediments or find their way along food chains. Perhaps not so surprisingly, it is common to find elevated levels of pesticides in estuarine sediments decades after their embargo. Still, it remains challenging to address ecotoxicity in circumstances that invariably imply mixtures of contaminants and multiple factors affecting bioavailability. Despite advances in methods for detecting pesticides in waters, sediments and organisms, chemical data alone are insufficient to predict risk. Many researchers have been opting for ex situ bioassays that mimic the concentrations of pesticides in estuarine waters and sediments using a range of ecologically relevant model organisms, with emphasis on fish, molluscs and crustaceans. These experimental procedures unravelled novel risk factors and important insights on toxicological mechanisms, albeit with some prejudice of ecological relevance. On the other hand, in situ bioassays, translocation experiments and passive biomonitoring strive to spot causality through an intricate mesh of confounding factors and cocktails of pollutants. Seemingly, the most informative works are integrative approaches that combine different assessment strategies, multiple endpoints and advanced computational and geographical models to determine risk. State-of-art System Biology approaches combining high-content screening approaches involving "omics" and bioinformatics, can assist discovering and predicting novel Adverse Outcome Pathways that better reflect the cumulative risk of persisting and emerging pesticides among the wide range of stressors that affect estuaries. PMID- 29450676 TI - Comorbid obstructive sleep apnea and increased risk for sickle cell disease morbidity. AB - PURPOSE: Sickle cell disease (SCD) imparts an increased risk for obstructive sleep apnea (OSA) in childhood. Studies of pediatric SCD have identified an increased risk for pain and neurologic complications with comorbid OSA. We determined the rate of a broad range of SCD-related medical complications to better characterize the spectrum of SCD complications related to OSA. METHODS: Retrospective chart review at a single hematology clinic identified 641 youth with SCD who received consistent screenings for OSA as part of routine hematological health maintenance visits over an 11-year period. Medical complication rates in the 136 children with OSA determined by polysomnography exams were compared to 136 matched controls at lower risk for OSA due to negative OSA screenings or exams. RESULTS: Children with SCD and OSA had higher overall rates of SCD complications than low OSA-risk controls; lung morbidity showed the largest effect size. Infection, cardiovascular, and neurologic complications occurred at higher rates in children with OSA. Children with comorbid OSA had higher rates of SCD complications both before and after OSA diagnosis. CONCLUSIONS: OSA in children with SCD is associated with higher rates of a broad range of SCD complications, including pneumonia and acute chest syndrome. Routine screenings, diagnosis, and increased therapeutic intervention for children with comorbid OSA could decrease SCD morbidity.

AB - Purpose This study examined who benefits most from a cognitive behavioural therapy (CBT)-based intervention that aims to enhance return to work (RTW) among employees who are absent due to common mental disorders (CMDs) (e.g., depression, anxiety, or adjustment disorder). We researched the influence of baseline work related self-efficacy and mental health (depressive complaints and anxiety) on treatment outcomes of two psychotherapeutic interventions. Methods Using a quasi experimental design, 12-month follow-up data of 168 employees were collected. Participants either received work-focused cognitive behavioural therapy (W-CBT) that integrated work aspects early into the treatment (n = 89) or regular cognitive behavioural therapy (R-CBT) without a focus on work (n = 79). Results Compared with R-CBT, W-CBT resulted in a faster partial RTW, irrespective of baseline self-efficacy. Among individuals with high self-efficacy, W-CBT also resulted in faster full RTW. The effectiveness of W-CBT on RTW did not depend on baseline depressive complaints or anxiety. The decline of mental health complaints did not differ between the two interventions, nor depended on baseline self-efficacy or mental health. Conclusions Considering the benefits of W-CBT for partial RTW, we recommend this intervention as a preferred method for employees with CMDs, irrespective of baseline self-efficacy, depression and anxiety. For individuals with high baseline self-efficacy, this intervention also results in higher full RTW. For those with low self-efficacy, extra exercises or components may be needed to promote full RTW.

AB - Silver nanoparticles (AgNPs) have recently emerged as a powerful agents for disinfection in the poultry industry. AgNPs are capable of epithelial barriers passing from the route of exposure to the vital organs and cells. This study evaluated the effects of AgNPs on organs weights, blood biochemical, hematological, and coagulation parameters, antioxidant enzyme activities, and histopathological changes and silver concentrations of liver and kidney tissues in laying Japanese quails after exposure to the nanoparticles. The layer quails were randomly assigned to 4 groups, consisting of six replicates, three quails each. The treatments included 0, 4, 8, and 12 mg/L of AgNPs in daily drinking water for 30 weeks. AgNPs decreased the relative weight of liver, ileum and large intestine (P < 0.05). Administration of AgNPs elevated plasma fibrinogen while decreased serum aspartate aminotransferase activity (P < 0.05). The antioxidant status of the liver showed that malondialdehyde level, an end product of lipid peroxidation, was higher (P < 0.05) and catalase activity was lower (P < 0.05) in the quails exposed to AgNPs. The accumulation of silver in the liver and kidney tissues were increased in a dose-dependent manner after exposure to AgNPs (P < 0.05). Histopathological findings showed reduced lipid vacuolization of hepatocytes in the 12 mg/L AgNPs treatment. In conclusion, the results indicated that AgNPs administration to drinking water can lead to oxidative stress and liver damage in laying quails which may be a predisposing for liver dysfunction.

AB - Despite the fact that Asians constituted a sizeable proportion of those exposed to the World Trade Center attack on September 11, 2001 due to its proximity to Chinatown and many South Asians working in the nearby buildings, no study had focused on examining the mental health impact of the attack in this group. Based on data collected by the World Trade Center Health Registry from a sample of 4721 Asians 2-3 years after the disaster, this study provides a baseline investigation for the prevalence and the risk and protective factors for PTSD among Asian Americans directly exposed to the attack and compared this population against 42,862 non-Hispanic Whites. We found that Asians had a higher prevalence of PTSD compared to Whites (14.6 vs 11.7%). "Race-specific factors" significantly associated to PTSD in the multivariate analyses were noted among sociodemographics: higher education was protective for Whites but a risk factor for Asians; being employed was protective for Whites but had no effect for Asians; and being an immigrant was a risk factor for Whites but had no effect for Asians. However, income was a protective factor for both races. Other "universal factors" significantly increased the odds of PTSD symptoms but showed no racial differences, including exposure to the disaster and the presence of lower respiratory symptoms which intensified odds of PTSD by the greatest magnitude (3.6-3.9 times). Targeted effort to reach out to Asians is essential for prevention and follow up treatment given this group's striking history of underutilization of mental health services.

The parameters are represented by the number of articles published in journals listed in the main international data banks, the total number of citations and the h index. Candidates with qualifications at least in two out of three parameters may access the national competitions for associate or full professor and apply for an academic appointment. This system developed with the aim to fight nepotism and promote meritocracy, progressively led to the deterioration of the Italian university system. Since promotion in academia is strictly dependent on publications the faculty members found the solution to get over this system by organizing themselves into large consortia or small groups with the purpose of sharing authorship in scientific publications. In this way parameter thresholds may be easily reached and even surpassed. An Italian adagio says: "Fatta la Legge, Trovato l'Inganno"; "Every law has its Loophole". However, there is no science without ethics and researchers must stay away from any kind of compromise. PMID- 29450683 TI - Common Adverse Effects of Novel Therapies for Multiple Myeloma (MM) and Their Management Strategies. AB - PURPOSE OF REVIEW: The purpose of this review was to evaluate management strategies for common adverse effects of novel therapies in multiple myeloma (MM), including immunomodulatory drugs, proteasome inhibitors, monoclonal antibodies, and a histone deacetylase inhibitor. RECENT FINDINGS: There are several adverse effects that occur across multiple classes of antimyeloma drugs, including rash, peripheral neuropathy, infusion reactions, and cardiotoxicity, but most can be managed without complete discontinuation of the agent or abandonment of the class. Additionally, several agents have critically important drug-drug interactions or dose-modification implications in hepatic or renal insufficiency that can be easily overlooked, and exacerbate adverse effects. As treatment of MM moves from fixed-duration traditional chemotherapy to novel agent based regimens, commonly administered continuously until disease progression or intolerable toxicities, providers must adopt their management strategies for both acute and long-term adverse effects. Early and frequent monitoring for therapy related complications, dose adjustments when needed, and timely treatment for toxicities are all important steps toward ensuring longevity of treatment from a limited array of therapeutic options that currently exist for a disease with a relapsing and remitting course. PMID- 29450684 TI - Application and impact of run-in studies. AB - BACKGROUND: A run-in phase is often employed prior to randomization in a clinical trial to exclude non-adherent patients, placebo responders, active drug non responders, or patients who do not tolerate the active drug. This may impact the generalizability of trial results. OBJECTIVE: To determine if clinical outcomes differed between randomized controlled trials with run-in phases compared with randomized controlled trials of the same medication without run-in phases. DESIGN, PARTICIPANTS: From 2006 to 2014, the Food and Drug Administration approved 258 new medications. Sitaglitpin, saxagliptin, linagliptin, and alogliptin were among the only drugs with a common mechanism of action that each had multiple clinical trials, some of which had run-in phases and some of which did not. We identified all published randomized controlled trials for these four medications from MEDLINE and EMBASE as well as prior systematic reviews. MAIN MEASURES: We extracted key measures of medication efficacy (reduction in hemoglobin A1C) and safety (serious adverse events) from qualifying trials. Study results were pooled for each medication using random effects meta-analysis. KEY RESULTS: We identified 106 qualifying trials for DPP4 inhibitors, of which 88 had run-in phases and 18 did not. The average run-in phase duration was 4.0 weeks (range 1-21), and 73% of run-in phases administered placebo rather than active drug. The reduction in hemoglobin A1C compared to baseline was similar for trials with and without run-in phases (0.70%, 95% confidence interval [CI] 0.65-0.75 vs 0.76%, 95% CI 0.69-0.84, p = 0.27). The proportion of patients with serious adverse events was also similar for trials with and without run-in phases (4%, 95% CI: 3-5% vs 3%, 95% CI: 1-4%, p = 0.35). CONCLUSION: Trials with run-in phases provided similar estimates for medication efficacy and safety compared to trials without run-in phases. Because run-in phases are costly and time consuming, these results call their utility into question for clinical trials of short duration.

AB - INTRODUCTION: Emergency laparotomy (EL) is a commonly performed operation with increased morbidity and mortality. Currently, there is a lack of published outcomes following emergency laparotomy within an Irish population. The aim of this study was to assess our outcomes and compare these to predefined outcomes from NELA. METHODS: A review of a prospectively maintained database of all patients who underwent an emergency laparotomy between January 1st 2015 and October 31st 2016 was performed. Patient demographics, operative indication and procedures, preoperative lactate, time of surgery, admission to high dependency unit (HDU) and mortality (30- and 90-day mortality) were included. Statistical analysis was performed using Minitab V18 with p < 0.05 considered significant. RESULTS: One hundred twenty-four emergency operations were performed on 120 patients. The median age was 60 years. Indications for surgery included the following (%): peritonitis (32.45%), obstruction (22.5%), complicated hernia (19.1%), mesenteric ischaemia (15%), trauma (4.1%), and acute haemorrhage (3.3%). A consultant surgeon and consultant anaesthetist were present at 79 and 78% of EL carried out, respectively. Reported 30- and 90-day mortality were 6.66 and 11.6%, respectively. Thirty-day mortality was 20% in octogenarians. Index lactate did not correlate with mortality (p = 0.43). A significant proportion of mortalities had procedures carried out between 6 pm and midnight with the highest mortality rate in patients with mesenteric ischaemia (p < 0.05). CONCLUSION: EL is associated with high mortality rates. Our mortality figures compare favourably with the NELA data. We support the development of a national database to facilitate improvements in the quality of care delivered to this high-risk cohort. PMID- 29450691 TI - Financial impact of inaccurate Adverse Event recording post Hip Fracture surgery: Addendum to 'Adverse event recording post hip fracture surgery'. AB - INTRODUCTION: A study in 2011 by (Doody et al. Ir Med J 106(10):300-302, 2013) looked at comparing inpatient adverse events recorded prospectively at the point of care, with adverse events recorded by the national Hospital In-Patient Enquiry (HIPE) System. METHODS: In the study, a single-centre University Hospital in Ireland treating acute hip fractures in an orthopaedic unit recorded 39 patients over a 2-month (August-September 2011) period, with 55 adverse events recorded prospectively in contrast to the HIPE record of 13 (23.6%) adverse events. With the recent change in the Irish hospital funding model from block grant to an 'activity-based funding' on the basis of case load and case complexity, the hospital financial allocation is dependent on accurate case complexity coding. A retrospective assessment of the financial implications of the two methods of adverse incident recording was carried out. RESULTS: A total of ?39,899 in 'missed funding' for 2 months was calculated when the ward-based, prospectively collected data was compared to the national HIPE data. Accurate data collection is paramount in facilitating activity-based funding, to improve patient care and ensure the appropriate allocation of resources. PMID- 29450692 TI - Expression of semaphorin class 3 is higher in the proliferative phase on the human endometrium. AB - PURPOSE: The semaphorins are related to angiogenesis and cell proliferation depending on the tissue. The purpose of this study was to assess gene expression of class 3 semaphorin (SEMA3A-F) and protein expression of semaphorin 3A (SEMA3A) within human endometrium throughout the menstrual cycle. METHODS: Gene expression of SEMA3A-F was analyzed by real-time PCR (qRT-PCR) and protein expression of SEMA3A was analyzed by ELISA in endometrial biopsies in the proliferative and secretory phase of the menstrual cycle. RESULTS: Gene expression of SEMA3A, SEMA3C, SEMA3D, and SEMA3E was statistically significant decreased in secretory compared to proliferative phase endometrium (p < 0.05). Accordingly, SEMA3A protein expression in the secretory phase was lower than protein expression in proliferative phase endometrium (p <= 0.05). CONCLUSION: SEMA3A, 3C, 3D, and 3E are possibly related to cell proliferation in the endometrium, being more expressed in the proliferative phase of the cycle. This finding may stimulate studies of class 3 semaphorins as a possible target for treatment of endometrial pathologies. PMID- 29450693 TI - The effect of assisted reproductive technology on the incidence of birth defects among livebirths. AB - PURPOSE: Our study objective is to examine the association between births conceived with assisted reproductive technology (ART) and birth defects using a large database from the United States. METHODS: Using the Centers for Disease Control and Prevention's Period-linked birth-infant death data files and fetal death database for 2011-2013, we conducted a retrospective cohort study comprised of live births that occurred in the USA during that time. Multivariate logistic regression was used to estimate the association between ART and birth defects, both overall and by specific defects. RESULTS: There were 11,862,780 live births between 2011 and 2013. Of these births, 11,791,730 were spontaneous pregnancies and 71,050 were conceived by ART, with an increasing trend in incidence of ART during the study period and an overall increasing trend of birth defects. Overall, infants conceived by ART had a greater risk of having birth defects than did infants conceived spontaneously (77/10,000 vs 25/10,000, respectively, OR 2.14, 95% CI 1.94-2.35). The malformations most commonly associated with ART were cyanotic heart defects (OR 2.74, 95% CI 2.42-3.09), cleft lip and/or palate (OR 1.47, 95% CI 1.14-1.89), and hypospadias (OR 1.77, 95% CI 1.42-2.19). There were no differences in risk of omphalocele or neural tube defects between the two groups. CONCLUSIONS: There is an overall and type-specific increased risk of birth defects in the ART population. Appropriate counseling and specialized ultrasound evaluations should be considered in pregnancies conceived by ART. PMID- 29450694 TI - Characteristics of women with mixed mass formation after evacuation following uterine artery chemoembolization for cesarean scar pregnancy. AB - PURPOSE: To explore the efficacy of treatment for early cesarean scar pregnancy (CSP) and to evaluate the characteristics of women with subsequent mixed mass formation. METHODS: Women with CSP, who received UACE followed by evacuation, were retrospectively analyzed. Clinical/sonographic characteristics in patients with or without mixed mass formation were compared. RESULTS: From a total of 395 cases, 105 cases had a pregnancy residual with mixed mass formation. Blood loss and subsequent salvage intervention were significantly lower in patients without mixed mass, although all women retained their uteri. It required 50 days for the mass to resolve, 40 days for beta-hCG concentrations to drop back to normal, and 61 days for menses to be restored; all of which were significantly longer than the same indices in women without a mixed mass. Clinical/sonographic characteristics predicting residual mass formation were maximal diameter of gestational sac (OR = 1.05, P = 0.001, with a sensitivity and specificity of 68.6 and 80.3%, respectively), presence of a fetal heart beat (OR = 2.63, P = 0.002, with a sensitivity and specificity of 62.9 and 67.2%, respectively), remnant myometrial thickness (OR = 108.91, P = 0.001 when thickness was less than 1 mm, with a sensitivity and specificity of 42.9% and 96.6%), location of gestational sac (OR = 59.20, P = 0.01 for complete type, with a sensitivity and specificity of 99.0 and 36.9%), and Doppler signal grading (OR = 8.08, P = 0.013 for Grade III, with a sensitivity and specificity of 83.8 and 51.0%). CONCLUSIONS: UACE followed by evacuation was effective for CSP and subsequent mixed mass formation could be predicted by some clinical/sonographic characteristics. PMID- 29450689 TI - The first multicenter, randomized, controlled trial of home telemonitoring for Japanese patients with heart failure: home telemonitoring study for patients with heart failure (HOMES-HF). AB - Home telemonitoring is becoming more important to home medical care for patients with heart failure. Since there are no data on home telemonitoring for Japanese patients with heart failure, we investigated its effect on cardiovascular outcomes. The HOMES-HF study was the first multicenter, open-label, randomized, controlled trial (RCT) to elucidate the effectiveness of home telemonitoring of physiological data, such as body weight, blood pressure, and pulse rate, for Japanese patients with heart failure (UMIN Clinical Trials Registry 000006839). The primary end-point was a composite of all-cause death or rehospitalization due to worsening heart failure. We analyzed 181 recently hospitalized patients with heart failure who were randomly assigned to a telemonitoring group (n = 90) or a usual care group (n = 91). The mean follow-up period was 15 (range 0-31) months. There was no statistically significant difference in the primary end-point between groups [hazard ratio (HR), 0.95; 95% confidence interval (CI), 0.548 1.648; p = 0.572]. Home telemonitoring for Japanese patients with heart failure was feasible; however, beneficial effects in addition to those of usual care were not demonstrated. Further investigation of more patients with severe heart failure, participation of home medical care providers, and use of a more integrated home telemonitoring system emphasizing communication as well as monitoring of symptoms and physiological data are required. PMID- 29450695 TI - A clinical approach to arrhythmias revisited in 2018 : From ECG over noninvasive and invasive electrophysiology to advanced imaging. AB - Understanding arrhythmias and their treatment is not always easy. The current straightforward approach with catheter ablation and device therapy is an amazing achievement, but does not make management of underlying or other cardiac disease and pharmacological therapy unnecessary. The goal of this paper is to describe how much of the knowledge of the 1980s and early 1990s can and should still be applied in the modern treatment of patients with arrhythmias. After an introduction, this review will focus on paroxysmal atrial fibrillation and a prototype of 'idiopathic' ventricular arrhythmias, two diseases with a striking similarity, and will discuss the arrhythmogenesis. The ECG continues to play an important role in diagnostics. Both diseases are associated with a structurally normal heart; the autonomic nervous system plays an important role in triggering arrhythmias at both the atrial and ventricular level. PMID- 29450696 TI - Neuroprotective Effects of Melatonin on Experimental Allergic Encephalomyelitis Mice Via Anti-Oxidative Stress Activity. AB - Multiple sclerosis (MS) is a chronic auto-inflammatory disease of the central nervous system (CNS) and hard to heal. This study aimed to investigate the effect of melatonin on mice with experimental autoimmune encephalomyelitis (EAE), a widely used MS model, and its potential mechanism underlying the action of MT on anti-oxidative stress. Female C57BL/6 mice were injected with MOG35-55 peptide to set up the EAE model, and for detection of the effect of melatonin (10 mg/kg i.p.) on the development and progression of EAE. Combining immunohistochemistry, biochemical technology and western blot approaches, the potential molecular mechanism of melatonin on EAE was evaluated as the levels of oxidative stress and the expression of Nrf2/ARE signal pathway. Our experiments showed a change of oxidative stress and Nrf2/ARE pathway expression in different groups, demonstrating that oxidative stress is associated with the pathophysiology of EAE. The administration of melatonin exerts neuroprotective effects against EAE, notably in suppressing the progression of EAE and pathological changes (lymphocytic infiltration). Furthermore, the effect of melatonin was probably related to decrease of the levels of oxidative stress, by activation of the Nrf2/ARE pathway and increased levels of anti-oxidant enzymes HO-1 and NQO1 expression. So, melatonin may be a promising reagent for intervention for multiple sclerosis in the future, and even for other autoimmune diseases. PMID- 29450698 TI - Validation of the Japanese Version of the Low Anterior Resection Syndrome Score. AB - BACKGROUND: The low anterior resection syndrome (LARS) score is a patient reported outcome measure to evaluate the severity of bowel dysfunction after rectal cancer surgery by scoring the major symptoms of LARS. The aim of this study was to translate the English version of the LARS score into Japanese and to investigate the validity and reliability of the LARS score. METHODS: The LARS score was translated in Japanese following current international recommendations. A total of 149 rectal cancer patients completed the LARS score questionnaire and were also asked a single question assessing the impact of bowel function on quality of life (QoL). A total of 136 patients answered the LARS score questionnaire twice. RESULTS: The Japanese LARS score showed high convergent validity, based on its good correlation between the LARS score and QoL (p < 0.001). The LARS score was able to discriminate between patients according to the tumor distance to anal verge (p < 0.001), type of surgery (p < 0.001), and time since surgery (p = 0.001). Patients after ultra-low anterior resection and intersphincteric resection showed especially high scores. The score also had high test-retest reliability (intraclass correlation coefficient: 0.87). CONCLUSION: The Japanese LARS score is a valid and reliable tool for measuring LARS. The LARS score is appropriate for assessments in postoperative bowel function and international comparison. Using this score, patient-reported outcome measures of LARS in Japanese patients can be shared internationally. Additional validation reports from non-English speaking countries can support the LARS score as a worldwide assessment tool for postoperative bowel dysfunction. PMID- 29450697 TI - Endogenous Sex Steroids Dampen Neuroinflammation and Improve Outcome of Traumatic Brain Injury in Mice. AB - The role of biological sex in short-term and long-term outcome after traumatic brain injury (TBI) remains controversial. The observation that exogenous female sex steroids (progesterone and estrogen) reduce brain injury coupled with a small number of clinical studies showing smaller injury in women suggest that sex steroids may play a role in outcome from TBI. We used the controlled cortical impact (CCI) model of TBI in mice to test the hypothesis that after CCI, female mice would demonstrate less injury than male mice, related to the protective role of endogenous steroids. Indeed, adult females exhibit histological protection (3.7 +/- 0.5 mm3) compared to adult male mice (6.8 +/- 0.6 mm3), and females that lacked sex steroids (ovex) showed increased injury compared to intact females. Consistent with histology, sensorimotor deficits measured as reduced contralateral limb use were most pronounced in male mice (31.9 +/- 6.9% reduced limb use) compared to a 12.7 +/- 3.8% reduction in female mice. Ovex mice exhibited behavioral deficits similar to males (31.5 +/- 3.9% reduced limb use). Ovex females demonstrated increased microglial activation relative to intact females in both the peri-injury cortex and the reticular thalamic nucleus. Ovex females also demonstrated increased astrogliosis in comparison to both females and males in the peri-injury cortex. These data indicate that female sex steroids reduce brain sensitivity to TBI and that reduced acute neuroinflammation may contribute to the relative protection observed in females. PMID- 29450699 TI - Consolidation/Tumor Ratio on Chest Computed Tomography as Predictor of Postoperative Nodal Upstaging in Clinical T1N0 Lung Cancer. AB - BACKGROUND: In clinical T1N0 peripheral lung cancers, lymph node upstaging is occasionally encountered postoperatively. However, nodal upstaging is rare in lung cancers presenting as ground-glass opacities. The aim of this study was to determine if lymph node upstaging could be reliably extrapolated from parameters such the consolidation/tumor ratio of chest computed tomography. METHODS: We conducted a retrospective study of 486 patients treated for peripheral clinical T1N0 non-small cell lung cancer, each undergoing lobectomy with mediastinal lymph node dissection. We compared preoperative variables in the pathologic N0 and nodal upstaging groups, analyzing such variables to determine factors predictive of lymph node upstaging. RESULTS: Of the 486 patients studied, lymph node upstaging occurred in 42 (8.6%). In the upstaging group, the mean nodule diameter exceeded that of the pathologic N0 group (2.3 vs 1.9 cm, respectively; p < 0.001), and the mean consolidation/tumor ratio was larger in the upstaging group than the pN0 group (0.95 vs 0.68, respectively; p < 0.001). Nodule diameter and consolidation/tumor ratio emerged as significant predictive factors for lymph node upstaging after surgery in a multivariate analysis (hazard ratio [HR] 2.259, p = 0.039; HR 173.645, p = 0.001, respectively). CONCLUSIONS: Consolidation/tumor ratio and nodule diameter are significant predictive factors of postoperative lymph node upstaging. The higher the consolidation/tumor ratio and smaller the nodule diameter, the less likely the occurrence of postoperative lymph upstaging would be in clinical T1N0 peripheral non-small cell lung cancer.

PMID- 29450701 TI - Burden, Characteristics and Process of Care Among the Pediatric and Adult Trauma Patients in Botswana's Main Hospitals. AB - BACKGROUND: Botswana is notable among countries with high rates of Road Traffic Collisions (RTC); like many other lower-middle-income countries (LMICs), it lacks trauma systems. The World Health Organization recommends 'Essential Trauma Care' in countries with no formal trauma systems. The proportion of injuries in Emergency Departments and the care process were investigated to gain an overview for enabling the design of a relevant LMICs trauma system. METHOD: Blunt and penetrating trauma patients were included from three major hospitals, examining the proportion of injuries, patient characteristics, the care process and comparing these between pediatrics and adults. Data are presented using descriptive statistics. RESULTS: The proportion of trauma ranged between 6 and 10% of Emergency Department cases. Pediatrics constituted 19%, and 59% of all patients were male. The median age was 28 years [IQR 17-39] and 8 years [IQR 4 11] for adults and pediatrics, respectively. The leading causes of injuries were: falls in pediatrics (55%) and interpersonal violence in the adults (34%), followed by RTC in both children (20%) and adults (30%). The public inter hospital vehicles transported 77% of pediatrics and 69% of adults, while formal ambulance transported only 9% of pediatrics and 22% of adults. The median Emergency Department waiting time for pediatrics was 187 min [IQR 102-397] and for adults was 208 min [IQR 100-378]: Most were triaged as non-urgent (70% pediatrics and 72% adults), and the majority were discharged (84% pediatrics and 76% adults). CONCLUSION: The Emergency Department workload of injuries is notably high, with differing mechanisms of injury and transport modes between pediatrics and adults: Waiting time is severely prolonged for urgent and critical patients. Diagnoses, triage categories and patients disposition were similar. PMID- 29450702 TI - Establishment and characterization of the NCC-SS1-C1 synovial sarcoma cell line. AB - Synovial sarcoma is an aggressive mesenchymal malignancy characterized by unique gene fusions. Tissue culture cells are essential tools for further understanding tumorigenesis and anti-cancer drug development; however, only a limited number of well-characterized synovial sarcoma cell lines exist. Thus, the objective of this study was to establish a patient-derived synovial sarcoma cell line. We established a synovial sarcoma cell line from tumor tissue isolated from a 72 year-old female patient. Prepared cells were analyzed for the presence of gene fusions by fluorescence in situ hybridization, RT-PCR, and karyotyping. In addition, the resulting cell line was characterized by viability, short tandem repeat, colony and spheroid formation, and invasion analyses. Differences in gene enrichment between the primary tumor and cell line were examined by mass spectrometric protein expression profiling and KEGG pathway analysis. Our analyses revealed that the primary tumor and NCC-SS1-C1 cell line harbored the SS18-SSX1 fusion gene typical of synovial sarcoma and similar proteomics profiles. In vitro analyses also confirmed that the established cell line harbored invasive, colony-forming, and spheroid-forming potentials. Moreover, drug screening with chemotherapeutic agents and tyrosine kinase inhibitors revealed that doxorubicin, a subset of tyrosine kinase inhibitors, and several molecular targeting drugs markedly decreased NCC-SS1-C1 cell viability. Results from the present study support that the NCC-SS1-C1 cell line will be an effective tool for sarcoma research. PMID- 29450703 TI - Utilization of hepatitis B core antibody positive grafts in living donor liver transplantation. AB - BACKGROUND: Utilization of liver grafts from hepatitis B core antibody (anti-HBc) positive donors carries the risk of reactivation of hepatitis B virus (HBV) in recipients because of post-transplant immunosuppressive therapy. METHODS: This was a retrospective study of patients who had received liver grafts from anti-HBc positive live donors between 2006 and 2016 at our institute. RESULTS: Out of 22 recipients [all males, mean age 45.4 years (range 18-64 years)], four patients were hepatitis B surface antigen (HBsAg) positive preoperatively and received entecavir post-transplantation. One among these patients who temporarily stopped entecavir had a recurrence of hepatitis B 39 months post-transplantation. Among the 13 non-immune [hepatitis B surface antibody (anti-HBs) < 10 mIU/mL] recipients, eight were prescribed lamivudine (100 mg daily) as monoprophylaxis. Four compliant patients remain negative for HBV so far. Out of the remaining four, two died secondary to sepsis unrelated to hepatitis B; two were non compliant and developed reactivation of hepatitis B. Lamivudine was missed out in five non-immune patients; three of them developed hepatitis B reactivation while two remain negative. Anti-HBs titer was immune in five patients. Over a period of 4 to 8 years follow up, three remain immune without prophylaxis, while two expired due to causes unrelated to hepatitis B. Following the detection of hepatitis B infection, five patients have been started on tenofovir 300 mg once daily. CONCLUSIONS: Anti-HBc positive liver grafts can be safely used for live donor liver transplantation. If the recipients are immune preoperatively, they can be merely followed up without HBV prophylaxis. However, it is extremely important to prophylactically treat the non-immune recipients with an antiviral agent lifelong. PMID- 29450705 TI - Modeling competence development in the presence of selection bias. AB - A major challenge for representative longitudinal studies is panel attrition, because some respondents refuse to continue participating across all measurement waves. Depending on the nature of this selection process, statistical inferences based on the observed sample can be biased. Therefore, statistical analyses need to consider a missing-data mechanism. Because each missing-data model hinges on frequently untestable assumptions, sensitivity analyses are indispensable to gauging the robustness of statistical inferences. This article highlights contemporary approaches for applied researchers to acknowledge missing data in longitudinal, multilevel modeling and shows how sensitivity analyses can guide their interpretation. Using a representative sample of N = 13,417 German students, the development of mathematical competence across three years was examined by contrasting seven missing-data models, including listwise deletion, full-information maximum likelihood estimation, inverse probability weighting, multiple imputation, selection models, and pattern mixture models. These analyses identified strong selection effects related to various individual and context factors. Comparative analyses revealed that inverse probability weighting performed rather poorly in growth curve modeling. Moreover, school-specific effects should be acknowledged in missing-data models for educational data. Finally, we demonstrated how sensitivity analyses can be used to gauge the robustness of the identified effects. PMID- 29450704 TI - Gulf Arabic nouns and verbs: A standardized set of 319 object pictures and 141 action pictures, with predictors of naming latencies. AB - Standardized pictorial stimuli and predictors of successful picture naming are not readily available for Gulf Arabic. On the basis of data obtained from Qatari Arabic, a variety of Gulf Arabic, the present study provides norms for a set of 319 object pictures and a set of 141 action pictures. Norms were collected from healthy speakers, using a picture-naming paradigm and rating tasks. Norms for naming latencies, name agreement, visual complexity, image agreement, imageability, age of acquisition, and familiarity were established. Furthermore, the database includes other intrinsic factors, such as syllable length and phoneme length. It also includes orthographic frequency values (extracted from Aralex; Boudelaa & Marslen-Wilson, 2010). These factors were then examined for their impact on picture-naming latencies in object- and action-naming tasks. The analysis showed that the primary determinants of naming latencies in both nouns and verbs are (in descending order) image agreement, name agreement, familiarity, age of acquisition, and imageability. These results indicate no evidence that noun- and verb-naming processes in Gulf Arabic are influenced in different ways by these variables. This is the first database for Gulf Arabic, and therefore the norms collected from the present study will be of paramount importance for researchers and clinicians working with speakers of this variety of Arabic. Due to the similarity of the Arabic varieties spoken in the Gulf, these different varieties are grouped together under the label "Gulf Arabic" in the literature. The normative databases and the standardized pictures from this study can be downloaded from http://qufaculty.qu.edu.qa/tariq-khwaileh/download-center/ . PMID- 29450706 TI - Transitions From Sexual Relationships Into Cohabitation and Beyond. AB - Much research on cohabitation has focused on transitions from cohabitation to marriage or dissolution, but less is known about how rapidly women progress into cohabitation, what factors are associated with the tempo to shared living, and whether the timing into cohabitation is associated with subsequent marital transitions. We use data from the 2006-2013 National Survey of Family Growth to answer these questions among women whose most recent sexual relationship began within 10 years of the interview. Life table results indicate that transitions into cohabitation are most common early in sexual relationships; nearly one quarter of women had begun cohabiting within six months of becoming sexually involved. Multivariate analyses reveal important social class disparities in the timing to cohabitation. Not only are women from more-advantaged backgrounds significantly less likely to cohabit, but those who do cohabit enter shared living at significantly slower tempos than women whose mothers lacked a college degree. In addition, among sexual relationships that transitioned into cohabiting unions, college-educated women were significantly more likely to transition into marriage than less-educated women. Finally, although the tempo effect is only weakly significant, women who moved in within the first year of their sexual relationship demonstrated lower odds of marrying than did women who deferred cohabiting for over a year. Relationship processes are diverging by social class, contributing to inequality between more- and less-advantaged young adults. PMID- 29450707 TI - Gender and the Residential Mobility and Neighborhood Attainment of Black-White Couples. AB - Including black-white couples in the study of residential stratification accentuates gendered power disparities within couples that favor men over women, which allows for the analysis of whether the race of male partners in black-white couples is associated with the racial and ethnic composition of their neighborhoods. I investigate this by combining longitudinal data between 1985 and 2015 from the Panel Study of Income Dynamics linked to neighborhood- and metropolitan-level data compiled from four censuses. Using these data, I assess the mobility of black male-white female and white male-black female couples out of and into neighborhoods defined respectively by their levels of whites, blacks, and ethnoracial diversity. My results show that the race of the male partner in black-white couples tends to align with the racial and ethnic composition of the neighborhoods where these couples reside. This finding highlights that the racial hierarchy within the United States affects the residential mobility and attainment of black-white couples, but its influence is conditioned by the race and gender composition of these couples. PMID- 29450708 TI - Metabolism of Rhizoma coptidis in Human Urine by Ultra-High-Performance Liquid Chromatography Coupled with High-Resolution Mass Spectrometry. AB - BACKGROUND AND OBJECTIVES: Rhizoma coptidis extract and its alkaloids were reported to exhibit various pharmacological activities. However, pharmacokinetics investigations indicated that the plasma concentrations of the alkaloids were too low to explain their systemic therapeutic actions. Thus, the metabolic profile of Rhizoma coptidis in humans is yet to be fully investigated and the present study aimed to investigate the metabolic profile of Rhizoma coptidis in human urine after oral administration of Rhizoma coptidis extract. METHODS: In this study, the metabolism of Rhizoma coptidis at a clinical dose (5 g/60 kg/day) was investigated using ultra-high-performance liquid chromatography coupled with high resolution LTQ-Orbitrap mass spectrometry. RESULTS: Totally, 30 constituents including 7 prototypes, 5 sulfation metabolites and 18 glucuronide conjugates were elucidated and identified on the basis of the characteristics of their high resolution precursor ions, product ions, and chromatographic retention times in human urine. Among the 7 prototypes, 3 prototypes (M20, M26 and M28) were identified definitely by comparing with standards. Based on the metabolites detected in human urine, a possible metabolic pathway of Rhizoma coptidis in vivo was proposed. CONCLUSIONS: The results demonstrated that the metabolic fate of Rhizoma coptidis mainly involved sulfation and glucuronidation in human urine and the glucuronide conjugate M14 (berberrubinen-9-O-glucuronide) might be a pharmacokinetic marker for Rhizoma coptidis alkaloids in humans. This study will be helpful to comprehensively understand the metabolic process of Rhizoma coptidis and how Rhizoma coptidis shows its pharmacological effects in humans. PMID- 29450709 TI - Biofilm formation and potential for iron cycling in serpentinization-influenced groundwater of the Zambales and Coast Range ophiolites. AB - Terrestrial serpentinizing systems harbor microbial subsurface life. Passive or active microbially mediated iron transformations at alkaline conditions in deep biosphere serpentinizing ecosystems are understudied. We explore these processes in the Zambales (Philippines) and Coast Range (CA, USA) ophiolites, and associated surface ecosystems by probing the relevance of samples acquired at the surface to in situ, subsurface ecosystems, and the nature of microbe-mineral associations in the subsurface. In this pilot study, we use microcosm experiments and batch culturing directed at iron redox transformations to confirm thermodynamically based predictions that iron transformations may be important in subsurface serpentinizing ecosystems. Biofilms formed on rock cores from the Zambales ophiolite on surface and in-pit associations, confirming that organisms from serpentinizing systems can form biofilms in subsurface environments. Analysis by XPS and FTIR confirmed that enrichment culturing utilizing ferric iron growth substrates produced reduced, magnetic solids containing siderite, spinels, and FeO minerals. Microcosms and enrichment cultures supported organisms whose near relatives participate in iron redox transformations. Further, a potential 'principal' microbial community common to solid samples in serpentinizing systems was identified. These results indicate collectively that iron redox transformations should be more thoroughly and universally considered when assessing the function of terrestrial subsurface ecosystems driven by serpentinization. PMID- 29450710 TI - Indicators for imaging in periorbital cellulitis secondary to rhinosinusitis. AB - PURPOSE: Our objective was to identify the clinical indicators for subperiosteal orbital abscess (SPOA) among patients who present with periorbital cellulitis secondary to rhinosinusitis, and to evaluate the need for performing a computerized tomography (CT) scan. METHODS: A retrospective cohort study of all patients admitted to our tertiary care emergency department between 2006 and 2014 was conducted. Included were healthy patients with acute periorbital cellulitis secondary to rhinosinusitis. Variables analyzed included age, gender, duration of symptoms, previous antibiotic therapy, highest recorded temperature, physical examination findings, ophthalmologist's examination results, laboratory results, and interpretation of imaging studies, when performed. RESULTS: Of the 123 identified patients, 78 (63%) were males, with a mean age of 4 years (range 1 70). 68 patients were categorized as Chandler's 1 disease, 2 as Chandler's 2, and 53 as Chandler's 3. 68 patients underwent a CT scan, of those 53 had SPOA. Proptosis and ophthalmoplegia were strongly associated with the presence of an abscess (P < 0.001). However, 14 patients with no ophthalmoplegia or proptosis who underwent a CT scan were older (mean age, 10 years; P < 0.028), and had higher neutrophil count of 78 versus 59% (P = 0.01). This group of patients had a clinically rapidly progressive disease, receiving wider broad-spectrum antibiotics or had their antibiotic treatment replaced to broader spectrum antibiotics through their course of treatment (48.2% compared to only 6.1%). CONCLUSIONS: We confirmed that patients with proptosis and/or limitation of extraocular movements are at high risk for developing SPOA, yet many do not have these predictors. Other features can identify patients who do not have proptosis and/or limitation of extraocular movements but do have significant risk of SPOA, and in these cases performing an imaging study is strongly suggested. PMID- 29450711 TI - Renal fat fraction and diffusion tensor imaging in patients with early-stage diabetic nephropathy. AB - OBJECTIVE: To investigate the renal fat fraction and water molecular diffusion features in patients with early-stage DN using Dixon imaging and diffusion tensor imaging (DTI). METHODS: Sixty-one type 2 diabetics (normoalbuminuria: n = 40; microalbuminuria: n = 21) and 34 non-diabetic volunteers were included. All participants received three-point Dixon imaging and DTI using a 3.0-T magnetic resonance imager. The fat fraction [FF] and DTI features [fractional anisotropy (FA), apparent diffusion coefficient (ADC), tract counts and length from DTI tractography] were collected. All image features were compared between cohorts using one-way ANOVA with Bonferroni post-hoc analysis. RESULTS: Renal FF in the microalbuminuric group was significantly higher than in the normoalbuminuric and control groups (5.6% +/- 1.3%, 4.7% +/- 1.1% and 4.3% +/- 0.5%, respectively; p < 0.001). Medullary FA in the microalbuminuric group was the lowest (0.31 +/- 0.06) in all cohorts. The tract counts and length in the renal medulla were significantly lower in the microalbuminuric group than in the other two groups. CONCLUSIONS: Dixon imaging and DTI are able to detect renal lipid deposition and water molecule diffusion abnormalities in patients with early-stage DN. Both techniques have the potential to noninvasively evaluate early renal impairment in type 2 diabetes. KEY POINTS: * Dixon imaging demonstrated renal fat deposition in early-stage DN; * Renal fractional anisotropy decreased in patients with early stage DN; * Renal tractography demonstrated reduced track counts and length in early-stage DN. PMID- 29450712 TI - Artifacts during the arterial phase of gadoxetate disodium-enhanced MRI: Multiple arterial phases using view-sharing from two different vendors versus single arterial phase imaging. AB - OBJECTIVES: To assess the usefulness of multiple arterial phase (AP) of gadoxetic acid-enhanced MRI using view-sharing of two different vendors to reduce transient severe motion (TSM) artifact in the AP. METHODS: This retrospective study included 298 patients (mean age 63 years) who underwent gadoxetic acid MRI with multiple AP from two different vendors; either triple (subcohort A, n=174) or quadruple (subcohort B, n=124) AP. 202 patients (143 vs. 59) underwent follow-up MRI with single AP. To compare multiple AP with single AP and between subcohorts, mean artifact score rated by two observers and frequency of significant artifacts were evaluated. Frequency of acquisition of late AP was also assessed. RESULTS: There was no difference in mean artifact score (p=0.086) or frequency of significant artifacts (p=0.219) between multiple AP and single AP. For the mean best score with multiple AP, subcohort B was better than subcohort A (p<0.001). Late AP was achieved more often with multiple AP (74.8 %, 98.3 %) than with single AP (64.3 %, 64.4 %). CONCLUSION: Multiple AP using different view-sharing failed to show differences in TSM artifacts in AP compared to single AP. Frequency of acquisition of late AP was higher with multiple AP. Mean best artifact score of multiple AP is different depending on view-sharing technique. KEY POINTS: * TSM artifacts were not significantly different between multiple AP and single AP. * The frequency of acquiring late AP was higher with multiple AP. * For multiple APs, TSM artifacts are different according to view-sharing technique. PMID- 29450713 TI - Radiomic signature as a diagnostic factor for histologic subtype classification of non-small cell lung cancer. AB - OBJECTIVES: To distinguish squamous cell carcinoma (SCC) from lung adenocarcinoma (ADC) based on a radiomic signature METHODS: This study involved 129 patients with non-small cell lung cancer (NSCLC) (81 in the training cohort and 48 in the independent validation cohort). Approximately 485 features were extracted from a manually outlined tumor region. The LASSO logistic regression model selected the key features of a radiomic signature. Receiver operating characteristic curve and area under the curve (AUC) were used to evaluate the performance of the radiomic signature in the training and validation cohorts. RESULTS: Five features were selected to construct the radiomic signature for histologic subtype classification. The performance of the radiomic signature to distinguish between lung ADC and SCC in both training and validation cohorts was good, with an AUC of 0.905 (95% confidence interval [CI]: 0.838 to 0.971), sensitivity of 0.830, and specificity of 0.929. In the validation cohort, the radiomic signature showed an AUC of 0.893 (95% CI: 0.789 to 0.996), sensitivity of 0.828, and specificity of 0.900. CONCLUSIONS: A unique radiomic signature was constructed for use as a diagnostic factor for discriminating lung ADC from SCC. Patients with NSCLC will benefit from the proposed radiomic signature. KEY POINTS: * Machine learning can be used for auxiliary distinguish in lung cancer. * Radiomic signature can discriminate lung ADC from SCC. * Radiomics can help to achieve precision medical treatment.

PMID- 29450715 TI - Utility of MRI for cervical spine clearance in blunt trauma patients after a negative CT. AB - PURPOSE: To determine the utility of cervical spine MRI in blunt trauma evaluation for instability after a negative non-contrast cervical spine CT. METHODS: A review of medical records identified all adult patients with blunt trauma who underwent CT cervical spine followed by MRI within 48 h over a 33 month period. Utility of subsequent MRI was assessed in terms of findings and impact on outcome. RESULTS: A total of 1,271 patients with blunt cervical spine trauma underwent both cervical spine CT and MRI within 48 h; 1,080 patients were included in the study analysis. Sixty-six percent of patients with a CT cervical spine study had a negative study. Of these, the subsequent cervical spine MRI had positive findings in 20.9%; 92.6% had stable ligamentous or osseous injuries, 6.0% had unstable injuries and 1.3% had potentially unstable injuries. For unstable injury, the NPV for CT was 98.5%. In all 712 patients undergoing both CT and MRI, only 1.5% had unstable injuries, and only 0.42% had significant change in management. CONCLUSIONS: MRI for blunt trauma evaluation remains not infrequent at our institution. MRI may have utility only in certain patients with persistent abnormal neurological examination. KEY POINTS: * MRI has limited utility after negative cervical CT in blunt trauma. * MRI is frequently positive for non-specific soft-tissue injury. * Unstable injury missed on CT is infrequent. PMID- 29450716 TI - Could IVIM and ADC help in predicting the KRAS status in patients with rectal cancer? AB - PURPOSE: To evaluate the diagnostic potential of DW-MRI relative parameters for differentiation of rectal cancers with different Kirsten rat sarcoma viral oncogene homologue (KRAS) mutation status. METHODS: Fifty-one patients with rectal cancer underwent diffusion-weighted MR imaging with eight b values. ADCs (including Max-ADC, Min-ADC and Mean-ADC) and IVIM parameters (D, pure diffusion; f, perfusion fraction; D*, pseudodiffusion coefficient) were respectively calculated by mono- and bi-exponential analysis. Patients were stratified into two groups: KRAS wild type and mutant. The DW-MRI-derived parameters between the KRAS wild-type group and KRAS mutant group were compared using the Mann-Whitney U test. Receiver-operating characteristic (ROC) analysis of discrimination between KRAS wild-type and KRAS mutant rectal cancer was performed for the DW-MRI-derived parameters. RESULTS: Max-ADC, Mean-ADC and D values were significantly lower in the KRAS mutant group than in the KRAS wild-type group, whereas a higher D* value was demonstrated in the KRAS mutant group. According to the ROC curve, Mean-ADC and D* values showed moderate diagnostic significance with the AUC values of 0.756 and 0.710, respectively. The cut-off values for Mean-ADC and D* were 1.43 * 10-3mm2/s and 26.58 * 10-3mm2/s, respectively. CONCLUSION: Rectal cancers had distinctive diffusion/perfusion characteristics in different KRAS mutation statuses. The DW-MRI-derived parameters, specifically Mean-ADC and D*, show a moderate diagnostic significance for KRAS status. KEY POINTS: * Rectal cancers with different KRAS mutation statuses demonstrated distinctive diffusion/perfusion characteristics. * Max-ADC, Mean-ADC and D values were lower in the KRAS mutant group. * A higher D* value was demonstrated in the KRAS mutant group. * IVIM-DW MRI may potentially help preoperative KRAS mutant status prediction. PMID- 29450717 TI - Prediction of infarct size and adverse cardiac outcomes by tissue tracking cardiac magnetic resonance imaging in ST-segment elevation myocardial infarction. AB - OBJECTIVES: We investigated whether quantification of global left ventricular (LV) strain by tissue tracking-CMR (TT-CMR) can estimate the infarct size and clinical outcomes in patients with acute myocardial infarction (MI). METHODS: We retrospectively registered 247 consecutive patients (58 +/- 12 years; male, 81%) who underwent 1.5-T CMR within 1 month after ST-segment elevation MI (median, 4 days; interquartile range, 3-6 days), and 20 age- and sex-matched controls (58 +/ 11 years; male, 80%). TT-CMR analysis was applied to cine-images to measure global LV radial, circumferential and longitudinal peak strains (GRS, GCS and GLS, respectively). Adverse cardiac events were defined as cardiac death and hospitalization for heart failure. RESULTS: During the follow-up (median, 7.8 years), 20 patients (8.1%) experienced adverse events. LV myocardial deformation was significantly decreased in MI patients compared to controls and closely related to the infarct size. The GRS, GCS and GLS were all significant predictors of adverse cardiac events. In particular, a GLS > -14.1% was independently associated with a > 5-fold increased risk for adverse events, even after adjustment for the LV ejection fraction and infarct size. CONCLUSIONS: TT-CMR derived LV strain is significantly related to the infarct size and adverse events. GLS measurement provides strong prognostic information in MI patients. KEY POINTS: * TT-CMR provides reliable quantification of LV strain in MI patients. * TT-CMR allows prediction of the infarct size and adverse events. * In particular, GLS by TT-CMR had independent prognostic value in MI patients. PMID- 29450718 TI - ADC as a useful diagnostic tool for differentiating benign and malignant vertebral bone marrow lesions and compression fractures: a systematic review and meta-analysis. AB - OBJECTIVES: To assess the sensitivity and specificity of quantitative assessment of the apparent diffusion coefficient (ADC) for differentiating benign and malignant vertebral bone marrow lesions (BMLs) and compression fractures (CFs) METHODS: An electronic literature search of MEDLINE and EMBASE was conducted. Bivariate modelling and hierarchical summary receiver operating characteristic modelling were performed to evaluate the diagnostic performance of ADC for differentiating vertebral BMLs. Subgroup analysis was performed for differentiating benign and malignant vertebral CFs. Meta-regression analyses according to subject, study and diffusion-weighted imaging (DWI) characteristics were performed. RESULTS: Twelve eligible studies (748 lesions, 661 patients) were included. The ADC exhibited a pooled sensitivity of 0.89 (95% confidence interval [CI] 0.80-0.94) and a pooled specificity of 0.87 (95% CI 0.78-0.93) for differentiating benign and malignant vertebral BMLs. In addition, the pooled sensitivity and specificity for differentiating benign and malignant CFs were 0.92 (95% CI 0.82-0.97) and 0.91 (95% CI 0.87-0.94), respectively. In the meta regression analysis, the DWI slice thickness was a significant factor affecting heterogeneity (p < 0.01); thinner slice thickness (< 5 mm) showed higher specificity (95%) than thicker slice thickness (81%). CONCLUSIONS: Quantitative assessment of ADC is a useful diagnostic tool for differentiating benign and malignant vertebral BMLs and CFs. KEY POINTS: * Quantitative assessment of ADC is useful in differentiating vertebral BMLs. * Quantitative ADC assessment for BMLs had sensitivity of 89%, specificity of 87%. * Quantitative ADC assessment for CFs had sensitivity of 92%, specificity of 91%. * The specificity is highest (95%) with thinner (< 5 mm) DWI slice thickness. PMID- 29450719 TI - Coronary plaque characteristics on baseline CT predict the need for late revascularization in symptomatic patients after percutaneous intervention. AB - OBJECTIVES: To assess pre-procedural plaque characteristics as determined by coronary CT angiography (CCTA) and their associations with late revascularization in symptomatic post-procedural patients. METHODS: Symptomatic patients with pre procedural CCTA were prospectively enrolled and referred for invasive coronary angiography (ICA). Plaque characterization was performed on the basis of baseline CCTA data. Multivariate logistic regression analysis with a stepwise selection method was performed to identify independent predictors of late revascularization. RESULTS: Seventy-eight patients with 134 lesions were included. Late revascularization was performed to treat 15 ISRs and 22 de novo lesions. Lesions with late revascularization showed higher prevalence rates of low-attenuation plaque (LAP) and positive remodelling (PR) (70.3% vs. 23.7% and 86.5% vs. 30.9%; both p < 0.001) at baseline CCTA. However, the incidence of spotty calcification or napkin-ring sign (NRS) was not significantly different between the subgroups. According to ROC curve analysis, PR and LAP showed the largest AUC values for diagnosing lesions with late revascularization (AUC = 0.78 and 0.73, both p < 0.001). In multivariate analysis, LAP and PR (odds ratio = 6.30 and 13.94; both p < 0.05) were revealed to be independent predictors for late revascularization. CONCLUSIONS: LAP and PR observed by baseline CCTA independently predict late revascularization caused by ISR or progression of de novo lesions. KEY POINTS: * LAP and PR observed by baseline CT are predictors of late revascularization. * NRS and spotty calcification are not associated with late revascularization. * CT plaque characterization is useful in identifying lesions at high risk of late revascularization. PMID- 29450721 TI - Analysis of changes in thermal growing season indices (tGSI) and their relations with some selected atmospheric teleconnection patterns (ATPs) over the northwest of Iran. AB - The daily minimum air temperature data from 18 stations located in the northwest of Iran during the period 1986-2015 was used to analyse the inter-annual variations and trends of thermal growing season indices (tGSI) and their relations with different atmospheric teleconnection patterns (ATPs). To analyze the changes in tGSI, tGSS (thermal growing season start), tGSE (thermal growing season end), and tGSL, the time period between tGSS and tGSE were considered. Using non-parametric Mann-Kendall and Spearman tests, the existence of a significant trend for time series of the tGSI and the correlation between ATPs and tGSI was evaluated. For eliminating the effect of serial correlation on test results, the trend-free pre-whitening approach was applied. Furthermore, residual bootstrap method was used to estimate the standard deviation of the Spearman correlation coefficient between tGSI and ATPs. The climate-based results showed the maximum tGSL increase (13.3 days per decade) for SA-C-M climate. For SH-K-W climate, the maximum significant trends for tGSS and tGSE were 9.6 (earlier start) and 10.8 (delay) days per decade, respectively. In general, in all statistically significant cases, the main cause of the extended tGSL was both earlier tGSS and delayed tGSE. In regional scale, it was found that the most effective teleconnection pattern on tGSS and tGSE are MEI (positive correlation), occurring during late winter and spring, and PDO index (negative correlation) in the summer, respectively. Moreover, the tGSL demonstrated the highest correlation (negative) with PDO with 1-month delay. The findings highlight that the inter annual variations of tGSI in northwest of Iran can be attributed to the influence of certain atmospheric teleconnection patterns such as MEI, PDO, NAO, AO, EA, and AMO. PMID- 29450720 TI - Diabetic Kidney Disease: Is There a Role for Glycemic Variability? AB - PURPOSE OF REVIEW: Diabetes is the leading cause of kidney disease globally. Diabetic kidney disease (DKD) is a heterogeneous disorder manifested as albuminuria and/or decreasing GFR. Hyperglycemic burden is the major contributor to the development of DKD. In this article, we review the evidence for the contribution of glycemic variability and the pitfalls associated with use of hemoglobin A1c (A1C), the gold standard for assessment of glucose control, in the setting of DKD. RECENT FINDINGS: Glycemic variability, characterized by swings in blood glucose levels, can result in generation of mitochondrial reactive oxygen species, a putative inciting factor for hyperglycemia-induced alterations in intracellular metabolic pathways. While there is indirect evidence supporting the role of glycemic variability in the pathogenesis of DKD, definitive data are lacking. A1C has many limitations and is a particularly suboptimal measure in patients with kidney disease, because its accuracy is compromised by variables affecting RBC survival and other factors. Continuous glucose monitoring (CGM) technology has the potential to enable us to use glucose as a more important clinical tool, for a more definitive understanding of glucose variability and its role in DKD. Glycemic variability may be a factor in the development of DKD, but definitive evidence is lacking. Currently, all available glycemic biomarkers, including A1C, have limitations and in the setting of DKD and should be used cautiously. Emerging data suggest that personal and professional CGM will play an important role in managing diabetes in patients with DKD, where risk of hypoglycemia is high. PMID- 29450723 TI - Molecular imaging and theranostic approaches in pheochromocytoma and paraganglioma. AB - Pheochromocytomas and their extra-adrenal counterpart paragangliomas (PGLs; together called PPGLs), belong to the family of neural crest-derived tumors. Given the overexpression of a wide variety of specific targets in PPGLs, it seems that these tumors are optimally suited to be imaged by specific radiopharmaceuticals. Thus, theranostics approaches with somatostatin agonists and antagonists are rapidly evolving in the setting of these tumors and may be considered as the next step in the therapeutic arsenal of metastatic PPGLs. PMID- 29450722 TI - Incidence and characteristics of chronic thromboembolic pulmonary hypertension in Germany. AB - BACKGROUND: The incidence of chronic thromboembolic pulmonary hypertension (CTEPH) is unknown. Previous studies from the United Kingdom and Spain have reported incidence rates of 1.75 and 0.9 per million, respectively. These figures, however, may underestimate the true incidence of CTEPH. METHODS: We prospectively enrolled patients newly diagnosed with CTEPH within 2016 in Germany. Data were obtained from the three German referral centers and from the German branch of COMPERA, a European pulmonary hypertension registry. The CTEPH incidence was calculated based on German population data, and patient characteristics and treatment patterns were described. RESULTS: A total of 392 patients were newly diagnosed with CTEPH within 2016 in Germany, yielding an incidence of 5.7 new cases per million adults. The (mean +/- standard deviation) age was 63.5 +/- 15.0 years; males and females were equally affected; 76.3% of the patients had a history of venous thromboembolism. A total of 197 (50.3%) patients underwent pulmonary endarterectomy. Almost all non-operated patients received targeted drug therapy, and 49 patients (25.1% of the non-operated patients) were treated with balloon pulmonary angioplasty. CONCLUSION: The incidence of CTEPH in Germany 2016 was 5.7 per million adults and thus higher than previously reported from other countries. Half of the patients were operated while the remaining patients received medical or interventional therapies. CLINICAL TRIALS REGISTRATION: http://www.clinicaltrials.gov NCT02660463 and NCT01347216. PMID- 29450724 TI - Chromaffin cell biology: inferences from The Cancer Genome Atlas. AB - Pheochromocytomas and paragangliomas (PCC/PGLs) are rare neuroendocrine tumors that are unusually diverse in metabolic profiles, in classes of molecular alterations and across a large number of altered genes. The Cancer Genome Atlas (TCGA) comprehensively profiled the molecular landscape of PCC/PGLs and identified novel genomic alterations and a new molecular classification of PCC/PGLs. In this review, we discuss the significant clinico-molecular findings of this integrated profiling study. We then review the molecular data of the TCGA cohort centering around known markers of sympathoadrenal cell lineage to better understand chromaffin cell biology. This analysis adds a new layer, that of chromaffin cell type, onto the published molecular classifications and in doing so provides inferences about underlying chromaffin cell biology and diversity. PMID- 29450725 TI - BDNF effects on dendritic spine morphology and hippocampal function. AB - Neurotrophins, including brain-derived neurotrophic factor (BDNF), are expressed in the hippocampus, as well as their precursors, the pro-neurotrophins. The neurotrophins signal through specific tyrosine kinase receptors and the low affinity receptor p75NTR. Moreover, the pro-neurotrophins are considered to be biologically active by signaling through specific receptors. The neurotrophins, especially BDNF, are involved in processes related to learning and memory. Furthermore, it is thought that BDNF also plays a crucial role in major depression. This points to a role of BDNF as a central regulator of neuronal plasticity within the postnatal hippocampus. Morphological correlates of neuronal plasticity are changes on the level of the dendritic spines and, at least in the dentate gyrus of the hippocampus, on the level of adult neurogenesis. Specific changes in dendritic spines as well as in adult hippocampal neurogenesis can be seen in the context of several forms of learning and memory, and it is known that depression is accompanied by declines in the rate of adult neurogenesis and in spine densities. The possible roles of BDNF in neuronal plasticity within the hippocampus are highlighted in this review by focusing on the morphological components of neuronal plasticity. PMID- 29450726 TI - C9orf72-associated neurodegeneration in ALS-FTD: breaking new ground in ribosomal RNA and nucleolar dysfunction. AB - Amyotrophic lateral sclerosis (ALS) and frontotemporal degeneration (FTD) are neurodegenerative diseases with distinct clinical appearance. However, both share as major genetic risk factor a C9orf72 locus intronic hexanucleotide expansion. The pathogenic pathways associated with the expansion-dependent neuronal toxicity are still poorly understood. Recent efforts to identify common threads of neuronal dysfunction have pointed towards deficits of ribosomal RNA (rRNA) biogenesis and loss of nucleolar integrity, a condition known as nucleolar stress that is an emerging shared feature among neurodegenerative diseases. Intriguingly, the C9orf72 mutation in ALS-FTD interferes with the function of the nucleolus by transcripts and dipeptide repeats (DPRs) produced by the hexanucleotide expansion. Experimental discrepancies have given rise to different hypotheses with regard to the connection of C9orf72 and nucleolar activity. In this review, we present and discuss emerging concepts concerning the impact of C9orf72 expansion on nucleolar biology. Moreover, we discuss the "nucleolar stress hypothesis," according to which nucleolar malfunction accompanies, exacerbates, or potentially triggers a degenerative phenotype. Upcoming awareness of the involvement of nucleolar stress in C9orf72 ALS-FTD could shed light into its pathogenesis, enabling potential treatment options aimed at shielding an "Achilles' heel" of neurons.

AB - PURPOSE: To explore whether muscle strength, the insulin-like growth factor axis (IGF-axis), height, and body composition were associated with serum 25 hydroxyvitamin D [25(OH)D] and affected by winter vitamin D supplementation in healthy children, and furthermore to explore potential sex differences. METHODS: We performed a double-blind, placebo-controlled, dose-response winter trial at 55oN. A total of 117 children aged 4-8 years were randomly assigned to either placebo, 10, or 20 ug/day of vitamin D3 for 20 weeks. At baseline and endpoint, we measured muscle strength with handgrip dynamometer, fat mass index (FMI), fat free mass index (FFMI), height, plasma IGF-1, IGF-binding protein 3 (IGFBP-3), and serum 25(OH)D. RESULTS: At baseline, serum 25(OH)D was positively associated with muscle strength, FFMI, and IGFBP-3 in girls only (all p < 0.01). At endpoint, baseline-adjusted muscle strength, FMI and FFMI did not differ between intervention groups. However, baseline-adjusted IGF-1 and IGFBP-3 were higher after 20 ug/day compared to placebo (p = 0.043 and p = 0.006, respectively) and IGFBP-3 was also higher after 20 ug/day compared to 10 ug/day (p = 0.011). Children tended to be taller after 20 ug/day compared to placebo (p = 0.064). No sex interactions were seen at endpoint. CONCLUSIONS: Avoiding the winter-related decline in serum 25(OH)D may influence IGF-1 and IGFBP-3 in children. Larger trials are required to confirm these effects, and the long-term implication for linear growth. PMID- 29450729 TI - Physical activity and Mediterranean diet based on olive tree phenolic compounds from two different geographical areas have protective effects on early osteoarthritis, muscle atrophy and hepatic steatosis. AB - PURPOSE: Osteoarthitis (OA) leads to progressive loss of articular cartilage, pain and joint disability. An acute injury constitutes an important risk factor for early OA, determining an inflammatory process responsible of cartilage degeneration and muscle atrophy, due to the joint pain and immobility. The study aims to assess the effects of conjugation of physical activity and diet enriched by olive tree compounds [extra virgin olive oil (EVOO) and olive leaf extract (OLE)], on the musculoskeletal system in OA rat model. METHODS: OA was induced by anterior cruciate ligament transection and confirmed by Mankin and OARSI scores. Rats were subjected to physical activity on treadmill 5 days a week for 10 min daily and fed with experimental diets (standard diet enriched with Sicilian EVOO, Tunisian EVOO and Tunisian EVOO-OLE) for 12 weeks. Immunohistochemistry was used to evaluate IL-6 and lubricin expression in cartilage tissue and ELISA was used to quantify these proteins in serum at different time points. Histology and histomorphometry analysis were done to valuate liver steatosis, muscle atrophy and cartilage pathological changes. RESULTS: Compared to the OA group, the experimental groups showed general increased lubricin and decreased IL-6 expression, significant muscle hypertrophy and no signs of liver steatosis, suggesting the beneficial effects of physical activity coupled with EVOO-enriched diets on rat articular cartilage. Interestingly, the best result was shown for Sicilian EVOO-enriched diet. CONCLUSION: In conclusion, the conjugation of physical activity and EVOO-enriched diet determines a significant articular cartilage recovery process in early OA. PMID- 29450727 TI - Metabolic implications of hypoxia and pseudohypoxia in pheochromocytoma and paraganglioma. AB - Hypoxia is a critical driver of cancer pathogenesis, directly inducing malignant phenotypes such as epithelial-mesenchymal transition, stem cell-like characteristics and metabolic transformation. However, hypoxia-associated phenotypes are often observed in cancer in the absence of hypoxia, a phenotype known as pseudohypoxia, which is very well documented in specific tumour types, including in paraganglioma/pheochromocytoma (PPGL). Approximately 40% of the PPGL tumours carry a germ line mutation in one of a number of susceptibility genes of which those that are found in succinate dehydrogenase (SDH) or in von Hippel Lindau (VHL) genes manifest a strong pseudohypoxic phenotype. Mutations in SDH are oncogenic, forming tumours in a select subset of tissues, but the cause for this remains elusive. Although elevated succinate levels lead to increase in hypoxia-like signalling, there are other phenotypes that are being increasingly recognised in SDH-mutated PPGL, such as DNA hypermethylation. Further, recently unveiled changes in metabolic re-wiring of SDH-deficient cells might help to decipher cancer related roles of SDH in the future. In this review, we will discuss the various implications that the malfunctioning SDH can have and its impact on cancer development.

PMID- 29450731 TI - Is mini-percutaneous nephrolithotomy a safe alternative to extracorporeal shockwave lithotripsy in pediatric age group in borderline stones? a randomized prospective study. AB - PURPOSE: The extracorporeal shockwave lithotripsy (ESWL) remains the most common first line of treatment for renal stones in the pediatric population. The purpose of this study is to evaluate and compare the outcomes of the ESWL and mini percutaneous nephrolithotomy (mini-PCNL). PATIENTS AND METHODS: A total of 108 patients younger than 12 years of age with 1-2 cm single renal stone (pelvic or calyceal) were randomized into two groups, each containing 54 patients. Patients in group A were subjected to mini-PCNL using 16.5 Fr percutaneous sheath while those in group B underwent ESWL using Dornier Compact Sigma. RESULTS: The stone free rate (SFR) after first session was 88.9% (48 cases) and 55.6% (30 cases) for groups A and B, respectively. The difference is highly statistically significant P = 0.006. Two patients (3.7%) in group A needed 2nd session of PCNL, while 18 patients (33.3%)in group B needed a 2nd session, of theses 18 patients six patients needed a 3rd session of ESWL. After the third session of ESWL and second look PCNL the stone-free rates were 92.59% (50 cases) and 88.89% (48 cases) for groups A and B, respectively, (P = 0.639), which is statistically insignificant. The mean hospital stay and fluoroscopy exposure were significantly longer in the mini-PCNL group. The complication rate in groups A and group B were (22.2%) and (14.8%), respectively, which is statistically insignificant (P = 0.484). CONCLUSIONS: According to Clavien grade of complications mini-PCNL is a safe procedure, and after three session of ESWL, mini-PCNL has a similar stone-free rate with a lower retreatment rate. However, the mini-PCNL has more radiation exposure, and requires a longer hospital stay. PMID- 29450732 TI - Combined prostatic urethral lift and remodeling of the prostate and bladder neck: a modified transurethral approach in the treatment of symptomatic lower urinary tract obstruction. AB - PURPOSE: The aim of the study was to evaluate the feasibility and safety of combining prostatic urethral lift (PUL) and a limited resection of the prostatic middle lobe or bladder neck incision in the treatment of lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH). METHODS: Twenty eight patients were treated at two tertiary centers and followed prospectively. Patient evaluations included patient characteristics, relief of LUTS symptoms, erectile and ejaculatory function, continence, operative time and adverse events. Patients were followed for a mean of 10.9 months. RESULTS: Patient characteristics were as follows: age 66 years (46-85), prostate volume 39.6 cc (22-66), preoperative IPSS/AUASI 20 (6-35)/QoL 3.9 (1-6)/peak flow 10.5 mL/s (4.0 19)/post-void residual volume (PVR) 123 mL (0-500). Mean operating time was 31 min (9-55). Postoperative complications were minor except for the surgical retreatment of one patient for blood clot retention (Clavien 3b). One patient required catheterization due to urinary retention. Reduction of symptoms (IPSS - 59.6%), increase in QoL (+ 49.0%), increase in flow (+ 111.5%), and reduction of PVR (- 66.8%) were significant. Antegrade ejaculation was always maintained. CONCLUSION: Our data suggest that a combination of PUL and transurethral surgical techniques is feasible, safe, and effective. This approach may be offered to patients with moderate size prostates including those with unfavorable anatomic conditions for PUL. This procedure is still 'minimally invasive' and preserves sexual function. In addition, it may add to a higher functional efficacy compared to PUL alone. STUDY REGISTER NUMBER: DRKS00008970. PMID- 29450733 TI - Miniaturised percutaneous nephrolithotomy versus flexible ureteropyeloscopy: a systematic review and meta-analysis comparing clinical efficacy and safety profile. AB - PURPOSE: This study aims to comparatively evaluate clinical outcomes of mini-PCNL and FURS for treating urinary tract calculi in a single session. METHODS: A systematic search using electronic databases was performed for studies comparing mini-PCNL and FURS for the treatment of urinary tract calculi. The primary outcome measurements were stone-free rates (SFRs) and complication rates for both techniques. Secondary outcome measurements were to compare patient demographics, operative duration, and inpatient stay. Meta-analysis was performed with Review Manager version 5.3 software. RESULTS: Sixteen studies on 1598 patients (n = 877 for mini-PCNL and n = 721 for FURS) met inclusion criteria. Demographics including age (p = 0.26), body mass index (BMI) (p = 0.51), and gender ratio (p = 0.6), were similar in both groups. Overall, SFR was significantly greater in the mini-PCNL group compared to the FURS group (n = 763/877, 89.3 +/- 8.4% versus n = 559/721, 80.1 +/- 13.3% [OR 2.01; 95% CI 1.53-2.64; p < 0.01]). Duration of inpatient stay was significantly greater in the mini-PCNL group compared to the FURS group (n = 877, 4 +/- 1.6 days versus n = 721, 2.5 +/- 2.2 days, respectively [WMD: 1.77; 95% CI 1.16-2.38, p < 0.01]. Overall complication rates were not significantly different between mini-PCNL and FURS (n = 171/877, 19.5 +/ 19.1% versus n = 112/721, 15.5 +/- 18.9%, respectively [OR 1.43; 95% CI 0.85 2.4, p = 0.18]). CONCLUSIONS: Mini-PCNL is associated with greater SFRs and longer inpatient stay compared to FURS. Complication rates were similar for both techniques. The advantages and disadvantages of both technologies should be familiar to urologists and conveyed to patients prior to urological intervention for nephrolithiasis. PMID- 29450734 TI - Two-hour post-challenge glucose is a better predictor of adverse outcome after myocardial infarction than fasting or admission glucose in patients without diabetes. AB - AIMS: We evaluate prevalence of new abnormal glucose tolerance (AGT) in post-MI survivors without known diabetes (DM) if guidelines are followed and compare the ability of admission (APG), fasting (FPG) and 2-h post-load plasma glucose (2h PG) to predict prognosis. METHODS: A total of 674 patients were followed up for 4 years for incidence of major adverse cardiovascular events (MACE) of cardiovascular death, non-fatal re-infarction or non-haemorrhagic stroke. Ability of models including APG, FPG and 2h-PG to predict MACE was compared. RESULTS: Of the total, 93-96% of impaired glucose tolerance and 64-75% of DM would be missed with current guidelines. MACE was higher in the upper quartiles of 2h-PG. When 2h PG and FPG were included simultaneously in models, only 2h-PG predicted MACE (HR 1.12, CI 1.04-1.20, p = 0.0012), all cause mortality (HR 1.17, CI 1.05-1.30, p = 0.0039), cardiovascular mortality (HR 1.17, CI 1.02-1.33, p = 0.0205) and non fatal MI (HR 1.10, CI 1.01-1.20, p = 0.0291). Adding 2h-PG significantly improved ability of models including FPG (chi2 = 16.01, df = 1, p = 0.0001) or FPG and APG (chi2 = 17.36, df = 1, p = 0.000) to predict MACE. Model including 2h-PG only had the lowest Akaike's information criteria and highest Akaike weights suggesting that this was the best in predicting events. Adding 2h-PG to models including FPG or APG with other co-variates yielded continuous net reclassification improvement (NRI) of 0.22 (p = 0.026) and 0.27 (p = 0.005) and categorical NRI of 0.09 (p = 0.032) and 0.12 (p = 0.014), respectively. Adding 2 h-PG to models including only FPG, only APG and both yielded integrated discrimination improvement of 0.012 (p = 0.015), 0.022 (p = 0.001) and 0.013 (p = 0.014), respectively. CONCLUSIONS: AGT is under-diagnosed on current guidelines. 2h-PG is a better predictor of prognosis compared to APG and FPG. PMID- 29450736 TI - Health and quality of life differ between community living older people with and without remaining teeth who recently received formal home care: a cross sectional study. AB - OBJECTIVE: To assess oral health, health, and quality of life (QoL) of care dependent community-living older people with and without remaining teeth who recently received formal home care. MATERIALS AND METHODS: For this cross sectional observational study, community-living older people (>= 65 years), who recently (< 6 months) received formal home care, were interviewed with validated questionnaires and underwent an oral examination. Oral health, general health, medicines usage, frailty (Groningen Frailty Indicator), cognition (Minimal Mental State Examination), QoL (RAND 36), and oral health-related QoL (Oral Health Impact Profile-14) were assessed. RESULTS: One hundred three out of 275 consecutive eligible older people (median age 79 [IQR (Inter Quartile Range) 72 85 years] participated in the study. Thirty-nine patients had remaining teeth and 64 were edentulous. Compared with edentulous older people, older people with remaining teeth scored significantly better on frailty, QoL, physical functioning, and general health. No significant differences were seen in cognition. Dental and periodontal problems were seen in more than half of the patients with remaining teeth. Two third of the edentulous patients did not visit their dentist regularly or at all. CONCLUSIONS: Care-dependent home-dwelling older people with remaining teeth generally were less frail, scored better on physical functioning and general health and had better QoL than edentulous older people. Dental and periodontal problems were seen in approximately 50% of the elderly. CLINICAL RELEVANCE: Notwithstanding their common dental problems, frailty, health, and QoL are better in home-dwelling older people with remaining teeth. To maintain this status, we advise not only dentists, but also health care workers and governments, to encourage people to maintain good oral health. PMID- 29450735 TI - N-acetyl-L-cysteine protects dental tissue stem cells against oxidative stress in vitro. AB - OBJECTIVES: The aim of our study was to investigate whether N-acetyl-L-cysteine (NAC) could protect stem cells from exfoliated deciduous teeth (SHED) against oxidative damage, during in vitro cultivation, to preserve regenerative potential of these cells. Accordingly, we examined the potential of cell culture supplementation with NAC in prevention of lipid peroxidation, unfavorable changes of total lipids fatty acid composition, and the effects on the activity of antioxidant enzymes. MATERIAL AND METHODS: We analyzed the extent of oxidative damage in SHED after 48 h treatment with different NAC concentrations. Cellular lipid peroxidation was determined upon reaction with thiobarbituric acid. All enzyme activities were measured spectrophotometrically, based on published methods. Fatty acid methyl esters were analyzed by gas-liquid chromatography. RESULTS: Concentration of 0.1 mM NAC showed the most profound effects on SHED, significantly decreasing levels of lipid peroxidation in comparison to control. This dose also diminished the activities of antioxidant enzymes. Furthermore, NAC treatment significantly changed fatty acid composition of cells, reducing levels of oleic acid and monounsaturated fatty acids and increasing linoleic acid, n-6, and total polyunsaturated fatty acid (PUFA) proportions. CONCLUSION: Low dose of NAC significantly decreased lipid peroxidation and altered fatty acid composition towards increasing PUFA. The reduced oxidative damage of cellular lipids could be strongly related to improved SHED survival in vitro. CLINICAL RELEVANCE: Low doses of antioxidants, applied during stem cells culturing and maintenance, could improve cellular characteristics in vitro. This is prerequisite for successful use of stem cells in various clinical applications. PMID- 29450737 TI - Correlation between plaque control and gingival health using short and extended oral hygiene intervals. AB - OBJECTIVES: To evaluate the correlation between dental plaque formation and gingival health in subjects performing high oral hygiene standards over short or extended intervals. MATERIALS AND METHODS: Fifty-two non-dental students volunteered for this study. The subjects, trained to perform high oral hygiene standards, were randomized to perform oral hygiene at 12-, 24-, 48-, or 72-h interval over 30 days. The plaque index (PlI) and the gingival index (GI) were evaluated at baseline, 15, and 30 days. For the statistical analysis, oral hygiene intervals were collapsed into daily (12 and 24 h; G12/24) and extended (48 and 72 h; G48/72) intervals. Summary statistics (mean +/- SD) and Spearman correlations between the PlI and the GI at baseline, 15, and 30 days were estimated. RESULTS: At baseline, correlation coefficients between PlI and GI were positive for both groups (r = 0.29 and r = 0.25). At day 15 and 30, correlation was maintained with similar baseline values for the G48/72 group. GI levels did not increase despite an increase in PlI for the G12/24 group, and the correlation was lower than that observed at baseline (r = 0.13 vs. r = 0.29). CONCLUSIONS: In subjects with high oral hygiene standards, the oral hygiene frequency governs the correlation between dental plaque formation and gingival health. Subjects performing high oral hygiene standards at daily intervals will maintain gingival health in difference to subjects using extended hygiene intervals. CLINICAL RELEVANCE: Subjects performing high oral hygiene standards at daily intervals will maintain gingival health in difference to subjects using extended hygiene intervals. PMID- 29450738 TI - Double-blind, randomized controlled clinical trial on analgesic efficacy of local anesthetics articaine and bupivacaine after impacted third molar extraction. AB - OBJECTIVE: The objective of this randomized controlled clinical trial (RCT) was to compare the effect of bupivacaine and articaine at habitual doses on pain intensity and the need for analgesics after lower third molar extraction. MATERIALS AND METHODS: The final study sample comprised 50 Caucasian volunteers (26 males and 24 females; age range, 18-30 years) undergoing scheduled surgical extraction of impacted lower third molar. A computer-generated random sequence was used to allocate participants to the articaine (4%) or bupivacaine (0.5%) group. Surgeons and patients were blinded by labeling the articaine and bupivacaine carpules with numbers (1 and 2, respectively). Postoperative pain intensity (primary outcome) was evaluated with a visual analogue scale (VAS), while the requirement for and timing of rescue medication and the quality of intraoperative anesthesia were also measured (secondary outcomes). RESULTS: VAS measured pain intensity was significantly higher (p < 0.05) in the articaine group than in the bupivacaine group at all time points except for 8 h post surgery (p = 0.052). Rescue medication was required by 13 (52%) patients in the articaine group and 8 (32%) patients in the bupivacaine group, although the difference did not reach statistical significance (p = 0.252). The groups did not significantly differ (p = 0.391) in the quality of the intraoperative anesthesia. CONCLUSIONS: Bupivacaine is a valid alternative to articaine in third molar surgery and may offer residual anesthesia as a means of reducing postoperative pain. However, further well-designed RCTs are required in larger study populations to verify the effectiveness of bupivacaine to achieve residual analgesia after oral surgery. CLINICAL RELEVANCE: These findings suggest that bupivacaine may be useful as a coadjuvant to control acute postoperative pain. TRIAL REGISTRATION: ACTRN12617001138370. PMID- 29450739 TI - Influence of operator skill level on the clinical outcome of non-surgical periodontal treatment: a retrospective study. AB - OBJECTIVES: The aim of this study is to evaluate the effect of operators experience and skill on treatment results of initial non-surgical periodontal therapy. MATERIALS AND METHODS: Initial periodontal treatment was carried out by either second-year periodontal residents (PR) or last year dental students (DS). From the treatment records of patients in each group, plaque and bleeding indices, and pocket depth (PD) at baseline and at re-evaluation were collected retrospectively on each tooth at six locations. Data were separated according to tooth type, area, and probing depth categories, sub-grouped to 1-3, 4-5, and >= 6 mm. RESULTS: Fifty and 49 records of DS and PR patients, accordingly, were analyzed. Initial periodontal treatment improved patient compliance in both groups and reduced signs of inflammation with significantly superior results in the PR group. Significant change in percentage of pockets was recorded in each category. The increase in percentage of sites with PD 1-3 mm and decrease in percentage of PD >= 6 mm pockets was significantly (p <= 0.001) superior in patients treated by PR. Percentage of 4-5 mm pockets was significantly reduced in both groups (p <= 0.01), with a significantly greater reduction in the mandibular molar and anterior teeth in the PR group. CONCLUSIONS: Experience and skill significantly affect the outcome of non-surgical periodontal therapy, with more positive improvement in patient compliance and clinical parameters when performed by a more qualified operator. CLINICAL RELEVANCE: Improvement of operator skills may decrease the number of residual pockets and increase patient compliance following non-surgical periodontal treatment. PMID- 29450740 TI - Perfluorocarbon induces alveolar epithelial cell response through structural and mechanical remodeling. AB - During total liquid ventilation, lung cells are exposed to perfluorocarbon (PFC) whose chemophysical properties highly differ from standard aqueous cell feeding medium (DMEM). We herein perform a systematic study of structural and mechanical properties of A549 alveolar epithelial cells in order to characterize their response to PFC exposure, using DMEM as control condition. Changes in F-actin structure, focal adhesion density and glycocalyx distribution are evaluated by confocal fluorescent microscopy. Changes in cell mechanics and adhesion are measured by multiscale magnetic twisting cytometry (MTC). Two different microrheological models (single Voigt and power law) are used to analyze the cell mechanics characterized by cytoskeleton (CSK) stiffness and characteristic relaxation times. Cell-matrix adhesion is analyzed using a stochastic multibond deadhesion model taking into account the non-reversible character of the cell response, allowing us to quantify the adhesion weakness and the number of associated bonds. The roles of F-actin structure and glycocalyx layer are evaluated by depolymerizing F-actin and degrading glycocalyx, respectively. Results show that PFC exposure consistently induces F-actin remodeling, CSK softening and adhesion weakening. These results demonstrate that PFC triggers an alveolar epithelial cell response herein evidenced by a decay in intracellular CSK tension, an adhesion weakening and a glycocalyx layer redistribution. These PFC-induced cell adjustments are consistent with the hypothesis that cells respond to a decrease in adhesion energy at cell surface. This adhesion energy can be even further reduced in the presence of surfactant adsorbed at the cell surface. PMID- 29450741 TI - Utility of cardiac computed tomography scanning in the diagnosis and pre operative evaluation of patients with infective endocarditis. AB - Transesophageal echocardiography (TEE) is the gold standard imaging study used in the diagnosis of infective endocarditis (IE). Computed tomography angiography (CTA) has undergone rapid advancement as a cardiac imaging technique and has previously shown promise in small non-randomized studies for evaluation of IE. We hypothesized that cardiac CTA would perform similarly to TEE in the detection of endocarditic lesions and that there would be no difference in clinical outcomes whether the coronary arteries were evaluated by CTA or invasive coronary angiography (ICA). 255 adults who underwent surgery for IE at the Mayo Clinic Rochester between January 1, 2006 and June 1, 2014 were identified retrospectively. 251 patients underwent TEE and 34 patients underwent cardiac CTA. TEE had statistically higher detection of vegetations (95.6 vs. 70.0%, p < 0.0001) and leaflet perforations (81.3 vs. 42.9%, p = 0.02) as compared to cardiac CTA. For detection of abscess/pseudoaneurysm TEE had a similar sensitivity to cardiac CTA (90.5 vs. 78.4%, p = 0.21). There was no significant difference in peri-operative outcomes whether coronary arteries were evaluated by CTA or ICA. The greatest advantage of cardiac CT in the setting of IE is its ability to couple the detection of complex cardiac anatomic abnormalities with coronary artery delineation, serving two important components of the diagnostic evaluation, particularly among patients who will require surgical intervention due to IE complications. Cardiac CTA may be considered as an alternate coronary artery imaging modality in IE patients with low to intermediate risk of disease but meet guideline recommendations for coronary artery imaging. PMID- 29450743 TI - Construction of a reverse genetic system for porcine astrovirus. AB - In order to construct a full-length infectious cDNA clone of porcine astrovirus, three fragments covering the complete genome of PAstV1-GX1 strain were amplified by RT-PCR. All three PCR-amplified fragments were cloned into T-Vector pMD19 (Simple), and subsequently assembled into a full-length cDNA clone by subcloning. A silent nucleotide change creating a PstI site was engineered into the full length cDNA clone to distinguish the rescued virus from the parental virus. Upon transfection of BHK-21 cells with the in vitro transcripts of both the original and constructed cDNAs, typical cytopathic effects were observed on PK-15 cells after serial passaging of the cell supernatant. The construction and recovery of the infectious cDNA clone of porcine astrovirus will provide a valuable experimental system to study the genome function and pathogenesis of astroviruses. PMID- 29450742 TI - Focused cardiac ultrasound as a predictor of readmission in acute decompensated heart failure. AB - Acute decompensated heart failure (ADHF) is a common reason for admission to the hospital, and readmission is frequent. Multiple factors contribute to rehospitalizations, but inadequate assessment of volume status leading to persistent congestion is an important factor. We sought to determine if focused cardiac ultrasound (FCU) of the inferior vena cava (IVC), as a surrogate of volume status, would predict readmission of ADHF patients after index hospitalization. Patients admitted with a primary diagnosis of ADHF were prospectively enrolled. All patients underwent FCU of the IVC on admission and then daily. 82 patients were enrolled. Patients demonstrated improvement in heart failure physical examination findings and symptoms during the hospitalization. There was a reduction in the size of the IVC and a significant increase in patients with small collapsible vena cava. Logistic regression analysis of physical examination, patient symptoms, and IVC parameters at discharge demonstrated IVC collapsibility and patient reported dyspnea improvement as the only significant variables to predict readmission or emergency department visit. FCU assessment of IVC size and collapsibility may be useful in patients with ADHF to predict risk of being readmitted within 30 days of hospital discharge. PMID- 29450744 TI - High-density lipoprotein (HDL) promotes angiogenesis via S1P3-dependent VEGFR2 activation. AB - High-density lipoprotein (HDL) has previously been shown to promote angiogenesis. However, the mechanisms by which HDL enhances the formation of blood vessels remain to be defined. To address this, the effects of HDL on the proliferation, transwell migration and tube formation of human umbilical vein endothelial cells were investigated. By examining the abundance and phosphorylation (i.e., activation) of the vascular endothelial growth factor receptor VEGFR2 and modulating the activity of the sphingosine-1 phosphate receptors S1P1-3 and VEGFR2, we characterized mechanisms controlling angiogenic responses in response to HDL exposure. Here, we report that HDL dose-dependently increased endothelial proliferation, migration and tube formation. These events were in association with increased VEGFR2 abundance and rapid VEGFR2 phosphorylation at Tyr1054/Tyr1059 and Tyr1175 residues in response to HDL. Blockade of VEGFR2 activation by the VEGFR2 inhibitor SU1498 markedly abrogated the pro-angiogenic capacity of HDL. Moreover, the S1P3 inhibitor suramin prevented VEGFR2 expression and abolished endothelial migration and tube formation, while the S1P1 agonist CYM-5442 and the S1P2 inhibitor JTE-013 had no effect. Last, the role of S1P3 was further confirmed in regulation of S1P-induced endothelial proliferation, migration and tube formation via up-regulation and activation of VEGFR2. Together, these findings argue that HDL promotes angiogenesis via S1P3-dependent up-regulation and activation of VEGFR2 and also suggest that the S1P-S1P3-VEGFR2 signaling cascades as a novel target for HDL-modulating therapy implicated in vascular remodeling and functional recovery in atherosclerotic diseases such as myocardial infarction and ischemic stroke. PMID- 29450745 TI - Clinical Management of Women with Monogenic Diabetes During Pregnancy. AB - PURPOSE OF REVIEW: Monogenic diabetes accounts for 1-2% of all diabetes cases, but is frequently misdiagnosed as type 1, type 2, or gestational diabetes. Accurate genetic diagnosis directs management, such as no pharmacologic treatment for GCK-MODY, low-dose sulfonylureas for HNF1A-MODY and HNF4A-MODY, and high-dose sulfonylureas for KATP channel-related diabetes. While diabetes treatment is defined for the most common causes of monogenic diabetes, pregnancy poses a challenge to management. Here, we discuss the key issues in pregnancy affected by monogenic diabetes. RECENT FINDINGS: General recommendations for pregnancy affected by GCK-MODY determine need for maternal insulin treatment based on fetal mutation status. However, a recent study suggests macrosomia and miscarriage rates may be increased with this strategy. Recent demonstration of transplacental transfer of sulfonylureas also raises questions as to when insulin should be initiated in sulfonylurea-responsive forms of monogenic diabetes. Pregnancy represents a challenge in management of monogenic diabetes, where factors of maternal glycemic control, fetal mutation status, and transplacental transfer of medication must all be taken into consideration. Guidelines for pregnancy affected by monogenic diabetes will benefit from large, prospective studies to better define the need for and timing of initiation of insulin treatment. PMID- 29450746 TI - Impact of habitat heterogeneity on zooplankton assembly in a temperate river floodplain system. AB - Dissimilar life features of Rotifera, Cladocera and Copepoda enable these organisms to respond differently to changes in the hydrological regime which influence alterations in environmental characteristics. We investigated the effect of habitat heterogeneity (e.g. eupotamal, parapotamal, palaeopotamal) on individual zooplankton group assemblages and biodiversity indices (alpha, beta and gamma diversity) during hydro regime change in floodplain waterbodies. Dissolved oxygen and organic nitrogen concentrations changed significantly among hydrological states while water depth was affected by both site and hydro regime replacement. Each studied site supported different zooplankton assemblage that highly depended on species-specific responses to hydro regime change. Also, individual zooplankton groups exhibited different correlations with specific environmental parameters regarding site change. Throughout the study, rotifers' local (alpha) and among-community (beta) diversities were susceptible to the site and inundation change while the microcrustacean biodiversity pattern diverged. Copepods highly discriminated different habitat types and hydrological phases at the regional scale (gamma diversity), while we found a complete lack of biodiversity dependence on both site and hydrology for Cladocera. Our results show that heterogeneous environments support the development of different zooplankton assemblages that express the within-group dissimilarities. They also point to the importance of identifying processes in hydrologically variable ecosystems that influence biodiversity patterns at an individual zooplankton group level.

PMID- 29450747 TI - Efficacy of Bifidobacterium breve Fermented Milk in Maintaining Remission of Ulcerative Colitis. AB - BACKGROUND: Fermented milk products containing Bifidobacterium breve strain Yakult (BFM) may improve clinical status in ulcerative colitis (UC) patients. AIMS: To assess efficacy of BFM in maintaining remission in Japanese patients with quiescent UC. METHODS: This double-blind study (B-FLORA) enrolled 195 patients with quiescent UC, randomized to receive one pack of BFM fermented milk per day [Bifidobacterium breve strain Yakult (10 billion bacteria) and Lactobacillus acidophilus (1 billion bacteria)] (n = 98) or matching placebo (n = 97) for 48 weeks. The primary efficacy endpoint was relapse-free survival (relapse: rectal bleeding score >= 2 on Sutherland disease activity index scale for 3 consecutive days and/or initiation of remission induction therapy for worsening of UC). RESULTS: An interim analysis was conducted after inclusion and follow-up of one-third of patients for the first phase of the study (n = 195). Relapse-free survival was not significantly different between the BFM and placebo groups (P = 0.643; hazard ratio 1.16; 95% CI 0.63-2.14, log-rank test), nor was the incidence of relapse. Therefore, the study was discontinued for lack of efficacy. An exploratory analysis of fecal samples from a subgroup of patients revealed no effects of either study beverage on intestinal microbiota, but there was a significant decrease in Bifidobacterium species before relapse, regardless of treatment group. Three mild adverse events occurred for which a causal relationship with the study beverage could not be ruled out (placebo: abdominal bloating and stress in one patient; BFM: body odor in one patient). CONCLUSIONS: BFM had no effect on time to relapse in UC patients compared with placebo. STUDY REGISTRATION: UMIN000007593. PMID- 29450749 TI - An Analysis of the Clinical, Laboratory, and Histological Features of Striped, Punctate, and Nodular Gastric Antral Vascular Ectasia. AB - BACKGROUND: Gastric antral vascular ectasia (GAVE) commonly presents as linear striped ("watermelon stomach") or punctate phenotypes, to which a newly discovered nodular form was recently added. AIMS: We performed a retrospective cohort study to detail and compare the clinical and histological characteristics of major GAVE phenotypes. METHODS: In 136 GAVE patients (tertiary care ambulatory and inpatient, median age 61.3 years, 73 men, and 63 women), clinical and laboratory results were recorded, with comorbidities, endoscopy indications, and complications of cirrhosis. In 74 patients, GAVE histopathology was cataloged by a pathologist masked to endoscopy results. RESULTS: Median age 61.3 years, 73 men, and 63 women. GAVE phenotypes were: linear striped-62 (46%), punctate-32 (24%), and nodular-41 (30%). Endoscopy was commonly performed for variceal screening in linear striped (45%) and nodular (34%) GAVE and for gastrointestinal bleeding in punctate (41%) and nodular (29%) GAVE, respectively. Of 89 cirrhotic patients, 37.5% each had linear striped or nodular GAVE, 24.7% had punctate forms (p = 0.03). Child-Turcotte-Pugh and Model for End-Stage Liver Disease scores were similar among phenotypes. Histologically, reactive epithelial hyperplasia and vascular ectasia were universal; smooth muscle proliferation was more common and consistent (78-86%) than microvascular thrombi (27-59%) and fibrohyalinosis (18 53%), which each varied with phenotype. CONCLUSIONS: Nodular GAVE is a gastric mucosal abnormality that is similar to the linear striped and punctate phenotypes, yet has distinct clinical and histological features. Increased awareness of nodular GAVE by endoscopists is needed to avoid its misdiagnosis as nonspecific antral nodules. PMID- 29450750 TI - Survival Impact of Stations of Pathological Lymph Nodes in N2 Non-small Cell Lung Cancer in a French Hospital. AB - BACKGROUND: The prognosis of lung cancer remains poor; only 20% of patients can undergo surgery. N2 non-small cell lung cancer (NSCLC) is a heterogeneous disease. We conducted a retrospective study to analyze the impact of N2 location on survival. METHODS: This study included 342 NSCLC with N2 involvement between 1988 and 2014. Patient-related data were collected through the CRB biobank and included demographic, therapeutic, and survival data. Survival was analyzed according to Kaplan-Maier method. Cox's regression analysis and analysis of variance (ANOVA) were used to determine factors significantly associated with survival. RESULTS: The population average age was 61.6 years; 82.2% were men, a majority were former smokers (87.1%), and 45.3% had adenocarcinoma. The main prognostic factors were male gender (p = 0.01), number of nodes (p < 0.0001), and tumor size (p < 0.0001). N2 disease had a poor survival (16 months) compared with N0 (32 months) and N1 (21.1 months) disease (p < 0.0001). The patients with involvement of station 4 (survival = 17.8 months) seemed to have a prognosis between those with station 7 (survival = 10.5 months) and N1 (survival = 22.6 months), p = 0.0005. CONCLUSIONS: N2 location has a prognostic impact in surgically NSCLC, and station 4 involvement has a better prognostic than station 7. PMID- 29450751 TI - Left Lobe Mobilization Strategy of Right-Sided Major Hepatectomy for Treatment of a Tumor Causing Severe Inferior Vena Cava Compression: A Novel Strategy Using the Modified Liver-Hanging Maneuver. AB - BACKGROUND: Massive bleeding during major hepatectomy is associated with greater mortality and morbidity.1 Our previous study shows that inferior vena cava (IVC) compression by tumor and an anterior approach without the liver-hanging maneuver (LHM) are risk factors for massive bleeding.2 The LHM is useful for controlling bleeding in deeper parenchymal transection planes.3 However, severe compression of the IVC by tumor makes it difficult to insert a hanging tape.4 The study shows a novel modified LHM strategy for severe IVC compression to minimize intraoperative bleeding. METHODS: The procedure was disassembled into six steps: (1) the glissonian bifurcation is encircled using an extrahepatic approach (2) the hepatic ligaments are dissected, and the root of each hepatic vein trunk is exposed (3) the left lobe is fully mobilized, and the short hepatic veins are carefully dissected with a systematic procedure established from hemi-left lobe procurement in living donor liver transplantation5 (4) the tape is inserted from the space between the right and middle hepatic vein trunks into the glissonian bifurcation along the anterior surface of the IVC (5) liver parenchymal transection is performed with upward pulling of the tape (6) the right hepatic vein is dissected, and the right lobe is dissected from the diaphragm and the right hepatic ligaments. RESULTS: Right hepatectomy with this procedure was performed for two patients with IVC compressed by hepatocellular carcinoma. The operative times were respectively 483 and 396 min. The respective estimated blood losses were 1195 and 485 ml, without transfusion. Both patients had acceptable outcomes without complications. CONCLUSION: The novel modified LHM strategy ensured minimal bleeding in the resection of a huge liver tumor causing severe IVC compression. PMID- 29450752 TI - Racial and Socioeconomic Differences in the Use of High-Volume Commission on Cancer-Accredited Hospitals for Cancer Surgery in the United States. AB - BACKGROUND: Although major cancer surgery at a high-volume hospital is associated with lower postoperative mortality, the use of such hospitals may not be equally distributed. OBJECTIVE: Our aim was to study socioeconomic and racial differences in cancer surgery at Commission on Cancer (CoC)-accredited high-volume hospitals. METHODS: The National Cancer Database (NCDB) was used to identify patients undergoing surgery for colon, esophageal, liver, and pancreatic cancer from 2003 to 2012. Annual hospital volume for each cancer was categorized using quartiles of patient volume. Patient-level predictors of surgery at a high-volume hospital, trends in the use of a high-volume hospital, and adjusted likelihood of surgery at a high-volume hospital in 2012 versus 2003 were analyzed. RESULTS: African American patients were less likely to undergo surgery at a high-volume hospital for esophageal (odds ratio [OR] 0.59, 95% confidence interval [CI] 0.49-0.73) and pancreatic cancer (OR 0.83, 95% CI 0.74-0.92), while uninsured patients and those residing in low educational attainment zip codes were less likely to undergo surgery at a high-volume hospital for esophageal, liver, and pancreatic cancer. In 2012, African Americans, uninsured patients, and those from low educational attainment zip codes were no more likely to undergo surgery at a high-volume hospital than in 2003 for any cancer type. These differences were not seen in colon cancer patients, for whom significant regionalization was not seen. CONCLUSIONS: Differences in the use of CoC-accredited high-volume hospitals for major cancer surgery were seen nationwide and persisted over the duration of the study. Strategies to increase referrals and/or access to high-volume hospitals for African American and socioeconomically disadvantaged patients should be explored. PMID- 29450753 TI - Use of Breast Imaging After Treatment for Locoregional Breast Cancer (AFT-01). AB - BACKGROUND: Annual mammography is recommended after breast cancer treatment. However, studies suggest its under-utilization for Medicare patients. Utilization in the broader population is unknown, as is the role of breast magnetic resonance imaging (MRI). Understanding factors associated with imaging use is critical to improvement of adherence to recommendations. METHODS: A random sample of 9835 eligible patients receiving surgery for stages 2 and 3 breast cancer from 2006 to 2007 was selected from the National Cancer Database for primary data collection. Imaging and recurrence data were abstracted from patients 90 days after surgery to 5 years after diagnosis. Factors associated with lack of imaging were assessed using multivariable repeated measures logistic regression with generalized estimating equations. Patients were censored for death, bilateral mastectomy, new cancer, and recurrence. RESULTS: Of 9835 patients, 9622, 8702, 8021, and 7457 patients were eligible for imaging at surveillance years 1 through 4 respectively. Annual receipt of breast imaging declined from year 1 (69.5%) to year 4 (61.0%), and breast MRI rates decreased from 12.5 to 5.8%. Lack of imaging was associated with age 80 years or older and age younger than 50 years, black race, public or no insurance versus private insurance, greater comorbidity, larger node-positive hormone receptor-negative tumor, excision alone or mastectomy, and no chemotherapy (p < 0.005). Receipt of breast MRI was associated with age younger than 50 years, white race, higher education, private insurance, mastectomy, chemotherapy, care at a teaching/research facility, and MRI 12 months before diagnosis (p < 0.05). CONCLUSION: Under-utilization of mammography after breast cancer treatment is associated with sociodemographic and clinical factors, not institutional characteristics. Effective interventions are needed to increase surveillance mammography for at-risk populations. ClinicalTrials.gov Identifier: NCT02171078. PMID- 29450754 TI - Neural Invasion is a Significant Contributor to Peritoneal Recurrence in Signet Ring Cell Gastric Carcinoma. AB - BACKGROUND: Gastric signet ring cell carcinoma (SRC) has shown a favorable outcome in early stages but has a worse prognosis than non-SRC in advanced stages. However, the cause for this stage-dependent prognostic impact has not been determined. This study aimed to compare clinicopathologic features and recurrence patterns between gastric SRC and non-SRC in a cohort of Eastern patients. METHODS: This study reviewed the prospectively collected data of 764 patients undergoing curative resection for gastric cancer from 2005 to 2008. The demographics, clinicopathologic characteristics, disease-specific survival (DSS) rate, and recurrence-free survival (RFS) rate of the patients were analyzed. RESULTS: The SRC patients (n = 176) had a worse prognosis than the non-SRC patients (n = 588), especially in stages T3 and T4. Peritoneal recurrence and the incidence of neural invasion (NI) were significantly increased in the SRC patients, albeit only in stages T3 and T4. In the T3 and T4 patients with NI, peritoneal recurrence occurred more frequently in SRC than in non-SRC (28.7% vs. 13.7%; p = 0.001), but not in the T3 and T4 patients without NI. Only in the patients with NI, SRC led to a significantly shorter DSS (67.6 vs. 90.7 months; p = 0.008) and RFS (67.1 vs. 80.3 months; p = 0.036) than non-SRC. CONCLUSIONS: This report is the first to present the relationship between NI and peritoneal recurrence as the cause of stage-dependent prognoses for SRC. A better understanding of NI may lend insight into cancer spread and recurrence, especially in gastric SRC. PMID- 29450755 TI - Efficacy of Adjuvant S-1 Versus XELOX Chemotherapy for Patients with Gastric Cancer After D2 Lymph Node Dissection: A Retrospective, Multi-Center Observational Study. AB - BACKGROUND: After curative resection of gastric cancer with D2 lymph node dissection, postoperative adjuvant chemotherapy with S-1 or capecitabine plus oxaliplatin (XELOX) is considered to be standard therapy in Eastern countries. This study aimed to compare the efficacies of adjuvant S-1 and XELOX chemotherapy for gastric cancer patients after D2 dissection based on disease-free survival (DFS). METHODS: This retrospective observational study was conducted at 29 tertiary hospitals in Korea. Of 1898 patients who underwent curative resection and received adjuvant chemotherapy for gastric cancer between February 2012 and December 2013, 1088 patients who met the eligibility criteria were enrolled in the study. After propensity score-matching, the 3-year disease-free survival rate (DFS) was used to compare efficacies directly between adjuvant XELOX and S-1 chemotherapies for patients with stage 2 or 3 gastric cancer after D2 gastrectomy. RESULTS: The 3-year DFS rates for the S-1 and XELOX groups did not differ significantly among disease stages 2A, 2B, and 3A (all p > 0.05). However, the survival rates for the S-1 group were significantly lower than for the XELOX group for stage 3B (65.8% vs. 68.6%; p = 0.019) and stage 3C (48.4% vs. 66.7%; p = 0.002) gastric cancer. The hazard ratios (HRs) of S-1 chemotherapy for recurrence compared with XELOX for stages 3B and 3C were respectively 2.030 [95% confidence interval (CI), 1.110-3.715; p = 0.022] and 2.732 (95% CI 1.427-5.234; p = 0.002). CONCLUSIONS: Adjuvant XELOX chemotherapy was more effective than S-1 for patients with stage 3B or 3C gastric cancer after D2 lymph node dissection. PMID- 29450756 TI - Risk Stratification According to the Prognostic Nutritional Index for Predicting Postoperative Complications After Lung Cancer Surgery. AB - BACKGROUND: The prognostic nutritional index (PNI), an immune nutritional marker based on serum albumin levels and total lymphocyte count, predicts postoperative complications in various types of malignancies. However, the clinical significance of the PNI for postoperative complications following lung cancer surgery is uncertain. METHODS: Patients with resected non-small cell lung cancer (n = 515) were retrospectively analyzed and the relationship between the preoperative PNI and postoperative complications was evaluated. RESULTS: Multivariate logistic regression analysis revealed that a preoperative low PNI was a significant independent predictor of postoperative complications of Clavien Dindo Grade >= II (odds ratio: 1.06 per unit decrease, 95.0% confidence interval 1.01-1.11). Patients were divided into three groups according to the preoperative PNI: normal (>= 50; n = 324), mildly low (< 50, >= 45; n = 134), and severely low (< 45; n = 57). The incidence of postoperative complications of Grade >= II and Grade >= III in the normal, mildly low, and severely low PNI groups was 22.2, 39.6, and 42.1% and 7.1, 16.4, and 22.8%, respectively. The incidence of postoperative complications of Grade >= II and Grade >= III was significantly higher in the mildly low and severely low PNI groups than in the normal PNI group (p < 0.001 and p < 0.001, respectively). The incidence of air leak, pneumonia, and extrapulmonary infection, but not arrhythmia, was significantly higher in the mildly low and severely low PNI groups than in the normal PNI group. CONCLUSIONS: The PNI could be a useful marker to predict the risk of postoperative complications after lung cancer surgery. PMID- 29450757 TI - Enhanced expression of ginsenoside biosynthetic genes and in vitro ginsenoside production in elicited Panax sikkimensis (Ban) cell suspensions. AB - Dual metabolite, i.e., ginsenoside and anthocyanin, co-accumulating cell suspensions of Panax sikkimensis were subjected to elicitation with culture filtrates of Serratia marcescens (SD 21), Bacillus subtilis (FL11), Trichoderma atroviridae (TA), and T. harzianum (TH) at 1.25% and 2.5% v/v for 1- and 3-week duration. The fungal-derived elicitors (TA and TH) did not significantly affect biomass accumulation; however, bacterial elicitors (SD 21 and FL11), especially SD 21, led to comparable loss in biomass growth. In terms of ginsenoside content, differential responses were observed. A maximum of 3.2-fold increase (222.2 mg/L) in total ginsenoside content was observed with the use of 2.5% v/v TH culture filtrate for 1 week. Similar ginsenoside accumulation was observed with the use of 1-week treatment with 2.5% v/v SD 21 culture filtrate (189.3 mg/L) with a 10 fold increase in intracellular Rg2 biosynthesis (31 mg/L). Real-time PCR analysis of key ginsenoside biosynthesis genes, i.e., FPS, SQS, DDS, PPDS, and PPTS, revealed prominent upregulation of particularly PPTS expression (20-23-fold), accounting for the observed enhancement in protopanaxatriol ginsenosides. However, none of the elicitors led to successful enhancement in in vitro anthocyanin accumulation as compared to control values. PMID- 29450758 TI - Overexpression of AlTMP2 gene from the halophyte grass Aeluropus littoralis in transgenic tobacco enhances tolerance to different abiotic stresses by improving membrane stability and deregulating some stress-related genes. AB - Herein, we report isolation of the AlTMP2 gene from the halophytic C4 grass Aeluropus littoralis. The subcellular localization suggested that AlTMP2 is a plasma membrane protein. In A. littoralis exposed to salt and osmotic stresses, the AlTMP2 gene was induced early and at a high rate, but was upregulated relatively later in response to abscisic acid and cold treatments. Expression of AlTMP2 in tobacco conferred improved tolerance against salinity, osmotic, H2O2, heat, and freezing stresses at the germination and seedling stages. Under control conditions, no growth or yield penalty were mentioned in transgenic plants due to the constitutive expression of AlTMP2. Interestingly, under greenhouse conditions, the seed yield of transgenic plants was significantly higher than that of non-transgenic (NT) plants grown under salt or drought stress. Furthermore, AlTMP2 plants had less electrolyte leakage, higher membrane stability, and lower Na+ and higher K+ accumulation than NT plants. Finally, six stress-related genes were shown to be deregulated in AlTMP2 plants relative to NT plants under both control and stress conditions. Collectively, these results indicate that AlTMP2 confers abiotic stress tolerance by improving ion homeostasis and membrane integrity, and by deregulating certain stress-related genes. PMID- 29450759 TI - Gene expression and population polymorphism of maize Iranian mosaic virus in Zea mays, and intracellular localization and interactions of viral N, P, and M proteins in Nicotiana benthamiana. AB - Maize Iranian mosaic virus (MIMV; Mononegavirales, Rhabdoviridae, Nucleorhabdovirus) infects maize and several other poaceous plants. MIMV encodes six proteins, i.e., nucleocapsid protein (N), polymerase cofactor phosphoprotein (P), putative movement protein (P3), matrix protein (M), glycoprotein (G), and large RNA-dependent RNA polymerase (L). In the present study, MIMV gene expression and genetic polymorphism of an MIMV population in maize were determined. N, P, P3, and M protein genes were more highly expressed than the 5' terminal G and L genes. Twelve single nucleotide polymorphisms were identified across the genome within a MIMV population in maize from RNA-Seq read data pooled from three infected plants indicating genomic variations of potential importance to evolution of the virus. MIMV N, P, and M proteins that are known to be involved in rhabdovirus replication and transcription were characterized as to their intracellular localization and interactions. N protein accumulated exclusively in the nucleus and interacted with itself and with P protein. P protein accumulated in both the nucleus and cell periphery and interacted with itself, N and M proteins in the nucleus. M protein was localized in the cell periphery and on endomembranes, and interacted with P protein in the nucleus. MIMV proteins show a distinctive combination of intracellular localizations and interactions. PMID- 29450760 TI - Association of facet tropism and orientation with lumbar disc herniation in young patients. AB - Facet tropism and orientation are thought to be associated with lumbar disc herniation (LDH), but the relationship is not well established. Moreover, the effect of facet joint on LDH has not been outlined in young patients. The objective of this study was to investigate the associations of facet joint tropism and orientation with LDH in young patients (18-35 years) by computed tomography (CT). Fifty-three patients with LDH and 129 with neither LDH nor low back pain (18-35 years) were included in this study. The facet joint angles were measured for each facet joint by CT as per the method described by Noren et al. We defined facet tropism as a bilateral angle difference > 5 degrees . Young cases with neither LDH nor low back pain were used as the control group. The results showed that LDH was significantly associated with more coronal facet joint orientation at L1-2 (p = 0.009), L2-3 (p = 0.004), and L3-4 (p = 0.004). No association was established between facet tropism and LDH. This study revealed that facet joint orientation was associated with LDH in young patients (18-35 years); they were more of coronal facing at upper levels. Also, the facet tropism was not associated with LDH. PMID- 29450761 TI - An electroglottographical analysis-based discriminant function model differentiating multiple sclerosis patients from healthy controls. AB - Dysarthrophonia is a predominant symptom in many neurological diseases, affecting the quality of life of the patients. In this study, we produced a discriminant function equation that can differentiate MS patients from healthy controls, using electroglottographic variables not analyzed in a previous study. We applied stepwise linear discriminant function analysis in order to produce a function and score derived from electroglottographic variables extracted from a previous study. The derived discriminant function's statistical significance was determined via Wilk's lambda test (and the associated p value). Finally, a 2 * 2 confusion matrix was used to determine the function's predictive accuracy, whereas the cross-validated predictive accuracy is estimated via the "leave-one out" classification process. Discriminant function analysis (DFA) was used to create a linear function of continuous predictors. DFA produced the following model (Wilk's lambda = 0.043, chi2 = 388.588, p < 0.0001, Tables 3 and 4): D (MS vs controls) = 0.728*DQx1 mean monologue + 0.325*CQx monologue + 0.298*DFx1 90% range monologue + 0.443*DQx1 90% range reading - 1.490*DQx1 90% range monologue. The derived discriminant score (S1) was used subsequently in order to form the coordinates of a ROC curve. Thus, a cutoff score of - 0.788 for S1 corresponded to a perfect classification (100% sensitivity and 100% specificity, p = 1.67e 22). Consistent with previous findings, electroglottographic evaluation represents an easy to implement and potentially important assessment in MS patients, achieving adequate classification accuracy. Further evaluation is needed to determine its use as a biomarker. PMID- 29450762 TI - Effect of prior application with and without post-injury treatment with low-level laser on the modulation of key proteins in the muscle repair process. AB - The aim of the present study was to evaluate the effects of LLLT prior to muscle injury with and without post-injury irradiation on the expression of isoforms of myosin heavy chain (MyHC), calcineurin (CaN), and myostatin during the repair process. Wistar rats were divided into five groups: control (n = 7); injury (n = 21); LLLT + injury (n = 21); injury + LLLT (n = 21), and LLLT + injury + LLLT (n = 21). Cryoinjury was performed on the tibialis anterior (TA) muscle. The injured groups were euthanized at 3, 7, and 14 days after injury. LLLT was performed using an infrared laser (780 nm) with the following parameters: 10 J/cm2, 40 mW, 10 s per point, 8 points, and 3.2 J of total energy. At the end of each period, the TA muscle was removed for the analysis of MyHC, CaN, and myostatin gene expression using real-time PCR. The data were tested statistically by Kruskal Wallis with Dunn's post hoc test (p < 0.05). The results demonstrated that prior irradiation reduced the mRNA expression of all proteins at 3 days. Post irradiation reduced the mRNA expression of MyHC-1, MyHC-2a, MyHC-2b, and CaN at 7 days. Prior irradiation combined with post-injury irradiation reduced the mRNA expression of MyHC-2x and CaN at 14 days and increased the mRNA expression of myostatin in the same period. In conclusion, different protocols of photobiomodulation can modulate the expression of the different isoforms of MyHC, CaN, and myostatin during the repair process. It is noteworthy that the combination of the prior and post-injury irradiation was the protocol that most promoted changes in the final phase of the repair process. PMID- 29450763 TI - Effects of 915 nm laser irradiation on human osteoblasts: a preliminary in vitro study. AB - Photobiomodulation (PBM) is a non-invasive treatment that uses laser or led devices making its effects a response to light and not to heat. The possibility of accelerating dental implant osteointegration and orthodontic movements and the need to treat refractory bone lesions, such as bisphosphonate related osteonecrosis of the jaws, has led researchers to consider the effects of PBM on bone for dentistry purposes. The aim of our study was to investigate the effects of 915 nm light supplied with a GaAs diode laser on human osteoblasts in vitro. Osteoblasts were isolated from mandibular cortical bone of a young healthy donor. The irradiation parameters were as follows: doses = 5, 15 and 45 J/cm2; power densities = 0.12 and 1.25 W/cm2; and irradiation times = 41.7, 125 and 375 s. We performed one irradiation per day for 3 and 6 days to study proliferation and differentiation, respectively. Microscopic analysis showed a greater amount of bone nodules in samples treated with 5 J/cm2 and 0.12 W/cm2 compared to controls (56.00 +/- 10.44 vs 19.67 +/- 7.64, P = 0.0075). Cell growth and quantification of calcium deposition did not show any differences when comparing irradiated and non-irradiated samples. Photobiomodulation, with the parameters investigated in the present study, positively modulated the mineralization process in human osteoblasts, inducing the formation of a greater amount of bone nodules, but did not increase cell proliferation. PMID- 29450764 TI - Impact of Well-being Interventions for Siblings of Children and Young People with a Chronic Physical or Mental Health Condition: A Systematic Review and Meta Analysis. AB - Siblings of children and young people with a chronic illness are at increased risk of poor psychological functioning. A number of studies have attempted to implement and evaluate interventions targeting the psychological well-being of this at-risk group. This systematic review summarises the evidence regarding psychological functioning of siblings following an intervention targeting their well-being. The meta-analysis considered behaviour and knowledge, two of the most frequently studied outcomes. The following databases were used: PsycINFO, EMBASE, CINAHL, PubMed, Scopus and Web of Science. Seventeen studies were eligible to be included in the systematic review and eight in the meta-analysis. Results from the systematic review reflected the inconsistency of intervention evaluations in this area with a high level of heterogeneity and a total of 23 outcomes considered across the 17 included studies. The meta-analysis estimated effect sizes using a standardised mean difference (SMD) approach. Pre-post analysis suggested significant improvement in behavioural outcomes and knowledge of their sibling's health conditions with a SMD of - 0.44 [95% CI (- 0.6, - 0.29); p = 0.000] and 0.69 [(95% CI = 0.42, 0.96); p = 0.000], respectively. The SMD was not significant for behavioural outcomes when considering treatment-control studies. In conclusion, the findings suggest interventions for well-being have a positive effect on the psychological functioning of siblings of children and young people with a chronic illness, but their specificity needs to be established. There is a need for further, more methodologically robust research in this area. PMID- 29450765 TI - Impact of platelet reactivity on 5-year clinical outcomes following percutaneous coronary intervention: a landmark analysis. AB - We investigated the impact of suboptimal platelet reactivity on clinical outcomes after percutaneous coronary intervention (PCI). We enrolled 500 patients with stable coronary artery disease undergoing elective PCI. Platelet reactivity was measured before PCI using the VerifyNow P2Y12 assay. Primary endpoint was the incidence of ischemic or bleeding events at 1 month and 5 years. Patients with high platelet reactivity (HPR) showed significantly higher rates of ischemic events both during the 1st month after PCI (HR 2.06, 95% CI 1.02-4.06), and beyond 1 month compared with patients without HPR (HR 1.73, 95% CI 1.02-2.95). Conversely, compared with patients without low platelet reactivity (LPR), patients with LPR presented significantly higher rates of bleeding only during the 1st month (HR 3.67, 95% CI 1.68-8.02). In conclusion, pre-procedural HPR is associated with ischemic events even beyond the 1st month after PCI. The association of LPR with bleeding events seems to be confined to the periprocedural period. PMID- 29450766 TI - Septal myectomy for hypertrophic cardiomyopathy: important surgical knowledge and technical tips in the era of increasing alcohol septal ablation. AB - Hypertrophic cardiomyopathy (HCM) is the most commonly inherited cardiac disease recent studies suggest a prevalence as high as 1 in 200. For symptomatic patients with obstructive HCM who are refractory to medical therapy, septal reduction is indicated. Septal myectomy (SM) is considered the gold standard septal reduction technique. However, due to a shortage of surgeons who are experienced in this technique, alcohol septal ablation (ASA) has overtaken SM as the most commonly performed procedure for obstructive HCM. In this review, we summarize the existing literature comparing SM with ASA and describe recent innovations in operative technique, including a detailed description of the approach used at our institution. PMID- 29450767 TI - Epididymo-orchitis caused by enteric organisms in men > 35 years old: beyond fluoroquinolones. AB - Epididymo-orchitis is a common urological condition in men of all ages, causing a unilateral or bilateral swelling of the epididymis and/or testis. It is frequently caused by sexually transmitted infections, Chlamydia trachomatis and Neisseria gonorrheae, as well as common enteric organisms implicated in urinary tract infections. Men over 35 years old may develop epididymo-orchitis associated with enteric organisms, often associated with functional bladder outlet problems such as benign prostatic hyperplasia or urethral stricture disease. Fluoroquinolones, especially ciprofloxacin, have long been the mainstay of treatment for these infections; however, rising resistance to ciprofloxacin in E. coli isolates in Europe and the USA means that there is an unprecedented necessity for alternative antimicrobials with adequate penetration into genital tissues (epididymis and testes) to allow appropriate and comprehensive treatment of epididymo-orchitis in this group of patients.

AB - Studies based on genome-wide single nucleotide polymorphisms (SNPs) supported the existence of two subpopulations in clonal complex (CC) 398 Staphylococcus aureus: an ancestral human-adapted clade (HC) and an animal-associated clade (AC). In this study, we have investigated the occurrence of genetic markers that allow discrimination of these subpopulations among CC398 isolates collected during 2014 to 2016 from human patients in Belgium. A collection of isolates was investigated by means of spa-typing and 16S-mecA-nuc PCR. CC398 isolates were classified as belonging to the human or the animal clade by using a canonical SNPs PCR and further studied by antimicrobial susceptibility and the presence of toxins, immune evasion cluster (IEC), and resistance genes. A total of 124 (7.8%) human isolates belonged to CC398. They were grouped into HC (n = 58) or AC (n = 66). The genes erm(T), pvl, chp, and scn were predominantly found in HC-CC398, while AC-CC398 isolates carried more frequently than the mecA, erm(C), tet(K), tet(M), and tet(L) genes. Different combinations of gene profiles were observed according to the clade. CC398 isolates from Belgian patients belonged to different subpopulations including typical HC and AC-isolates. Few HC-strains with mecA and AC-isolates harboring IEC were found. CC398 isolates from Belgian patients belonged to different subpopulations including typical HC and AC-isolates, as well as new emerging subpopulations that underline the ability of this lineage to acquire resistance and virulence genes. Further research is needed to evaluate the emergence of these subpopulations in the clinical setting.

AB - The Lot river, a major tributary of the downstream Garonne river, the largest river on the Northern side of the Pyrenees Mountains, was intensively studied in the 1970s. A pioneering program called "Lot Riviere Claire" provided a diagnosis of water quality at the scale of the whole watershed and proposed an ambitious program to manage nutrient pollution and eutrophication largely caused by urban wastewater releases. Later on, the implementation of European directives from 1991 to 2000 resulted in the nearly complete treatment of point sources of pollution in spite of a doubling of the basin's population. At the outlet of the Lot river, ammonium and phosphate contamination which respectively peaked to 1 mg N-NH4 L-1 and 0.3 mg P-PO4 L-1 in the 1980s returned to much lower levels in recent years (0.06 mg N-NH4 L-1 and 0.02 mg P-PO4 L-1), a reduction by a factor 15. However, during this time, nitrate contamination has regularly increased since the 1980s, from 0.5 to 1.2 mg N-NO3 L-1 in average, owing to the intensification of agriculture and livestock farming. Application of the Riverstrahler model allowed us to simulate the water quality of the Lot drainage network for the 2002-2014 period. We showed that, with respect to algal requirements, phosphorus and silica are well balanced, but nitrogen remains largely in excess over phosphorus and silica. This imbalance can be problematic for the ecological status of the water bodies. Using the model, for simulating various scenarios of watershed management, we showed that improvement of urban wastewater treatment would not result in any significant change in the river's water quality. Even though arable land occupies a rather limited fraction of the watershed area, only the adoption of better farming practices or more radical changes in the agro-food system could reverse the trend of increasing nitrate contamination. PMID- 29450771 TI - Fetal exposure markers of dioxins and dioxin-like PCBs. AB - Fetal exposure to polychlorinated biphenyls (PCBs), polychlorinated-p dibenzodioxins (PCDDs), and polychlorinated dibenzofurans (PCDFs) have been associated with a number of adverse health outcomes. Although the placenta acts as a barrier between the mother and the fetus, these contaminants transfer through the placenta exposing the fetus. Several studies have investigated placental transfer, but few have assessed the co-variation among these contaminants. Maternal blood, cord blood, and cord tissue were collected from 41 Japanese mother-infant pairs and analyzed for dioxin-like PCBs and PCDD/Fs. Hierarchical cluster analysis followed by principal component analysis were used to assess the co-variation. Two stable clusters of dioxin-like PCBs were found in maternal and cord blood. One cluster of low/medium chlorinated dioxin-like PCBs was present in all three matrices with 2,3',4,4',5-PeCB(#118) and 3,3',4,4',5 PeCB(#126) explaining the majority of the clusters' variances. Medium/high chlorinated dioxin-like PCBs clustered in maternal blood and cord blood but not in cord tissue. 2,3,4,4',5-PeCB(#114) and 2,3,3',4,4',5,5'-HpCB(#189) explained the majority of the clusters' variances. There was a substantial correlation between the sum of dioxin-like PCBs and total PCDD/F in all three matrices. The sum of the four suggested PCBs plus 3,3',4,4'-TeCB(#77) correlated well with total PCDD/F in all three matrices. Apart from the dioxin-like PCBs, little co variation existed among the studied contaminants. The five PCBs can be used as fetal exposure markers for dioxin and dioxin-like PCBs in maternal and cord blood respectively. In cord tissue, more higher chlorinated dioxin-like PCBs need to be measured as well.

AB - The Selenga River Basin (Mongolia and Russia) has suffered from heavy metal contamination by placer gold mining and urban activities in recent decades. The objectives of this study were to provide the first distribution data of dissolved organic matter (DOM) and humic substances (HS) in this data-scarce region, and to investigate their association with dissolved and colloidal metals. Two sampling campaigns were conducted in August of 2013 and 2014. A constant proportion of HS (%HS; coefficient of variation of 2%) was observed from the headwater of Tuul River to the end of the delta before Lake Baikal, spanning > 1000 km in distance. The relationships were determined as [HS] = 0.643 * [DOM] (R2 = 0.996, P < 0.001), and this value (%HS = 64.3) is recommended as an input parameter for metal speciation modeling based on samples collected from the rivers. The DOM and metal (Al and Fe) concentrations in samples doubled through the Zaamar Goldfield mining area, but the influence was mitigated by mixing with the larger Orkhon River, which has better water quality. Metals were mainly present as colloids and had a strong positive correlation with DOM (Al r = 0.81, P < 0.01; Fe r = 0.61, P < 0.01), suggesting that DOM sustains colloidal Al and Fe in solution and they are co-transported in the Selenga River Basin. Land use changes affect water quality and metal speciation and therefore have major implications for the fate of metals. PMID- 29450773 TI - Influence of Mn2+ ions on the corrosion mechanism of lead-based anodes and the generation of heavy metal anode slime in zinc sulfate electrolyte. AB - The influence of Mn2+ ions on the generation of heavy metal anode slime during zinc electrolysis industry was extensively investigated using several electrochemical methods, electron microscope technologies, and particle size analysis. Results showed that the Mn2+ could obviously promote oxygen evolution reaction (OER) and thereby weaken oxidation efficiency of Mn2+ (etaMnO2) and dissolution of Pb2+. The significant improvement in kinetic parameters for OER was found in electrolytes of 1 and 3 g/L Mn2+, but became unstable as the Mn2+ concentration increased to 10 g/L. This result was correlated with much different properties of oxide layers that its changes of microstructure are involved in, since it confirmed that the positive role of compact oxide layers in contributing to high corrosion resistance and activity for OER, but excessive Mn2+, resulted in its micromorphology of overthickness and instability. Such differences resulted from the effect of the Mn2+ concentration fluctuation on kinetic rates of the nucleation growth process. The formation and adsorption of intermediate MnO2-OHads identified as the controlled step for Mn2+ catalyzing OER was also recommended. The generation mechanism of anode slime was found to be changed in essence due to varying Mn2+ concentrations. In electrolyte of 1 g/L Mn2+, results revealed that the root cause of excessive small suspended anode slime (around 20 MUm) was the change of the initial pathway of Mn2+ electro-oxidation, whereas, it showed great improvement in the settling performance as the Mn2+ concentration was increased to 10 g/L. Considering the potential of optimizing Mn2+ concentrations as a cleaner approach to control anode slime, deepening the understanding of the impact mechanism of Mn2+ can provide new insights into intervention in the generation of anode slime.

AB - This study evaluated and compared the removal of antibiotics by industrial-scale composting and anaerobic digestion at different seasons. Twenty compounds belonged to three classes of widely used veterinary antibiotics (i.e., tetracyclines, sulfonamides, and quinolones) were investigated. Results show that of the three groups of antibiotics, tetracyclines were dominant in swine feces and poorly removed by anaerobic digestion with significant accumulation in biosolids, particularly in winter. Compared to that in winter, a much more effective removal (> 97%) by anaerobic digestion was observed for sulfonamides in summer. By contrast, quinolones were the least abundant antibiotics in swine feces and exhibited a higher removal by anaerobic digestion in winter than in summer. The overall removal of antibiotics by aerobic composting could be more than 90% in either winter or summer. Nevertheless, compost products from livestock farms in Beijing contained much higher antibiotics than commercial organic fertilizers. Thus, industrial composting standards should be strictly applied to livestock farms to further remove antibiotics and produce high quality organic fertilizer.

AB - Self-aggregation of bulk nano-hydroxyapatites (n-HAPs) undermines their immobilization efficiencies of heavy metals in the contaminated soils. Here, the low-cost, easily obtained, and environment-friendly filamentous fungi have been introduced for the bio-matrices of the hybrid bio-nanocomposites to potentially solve such problem of n-HAPs. According to SEM, TEM, XRD, and FT-IR analyses, n HAPs were successfully coated onto the fungal hyphae and their self-aggregation was improved. The immobilization efficiencies of diethylene-triamine-pentaacetic acid (DTPA)-extractable Cd and Pb in the contaminated soils by the bio nanocomposites were individually one to four times of that by n-HAPs or the fungal hyphae. Moreover, the Aspergillus niger-based bio-nanocomposite (ANHP) was superior to the Penicillium Chrysogenum F1-based bio-nanocomposite (PCHP) in immobilization of Cd and Pb in the contaminated soils. In addition, the results of XRD showed that one of the potential mechanisms of metal immobilization by the hybrid bio-nanocomposites was dissolution of n-HAPs followed by precipitation of new metal phosphate minerals. Our results suggest that the hybrid bio nanocomposite (ANHP) can be recognized as a promising soil amendment candidate for effective remediation on the soils simultaneously contaminated by Cd and Pb.

AB - Glutathione S-transferases are important detoxification enzymes involved in the metabolism of endogenous as well as exogenous compounds. Individuals differ in metabolic capacity due to inherited genetic variations. Due to the polymorphism exhibited by GSTT1 and GSTM1 that results in the complete loss of function, the present study was aimed towards the determination of the frequency distribution of GSTT1 and GSTM1 in agricultural workers in Punjab, India. The study aimed to investigate their contribution in susceptibility to increased disease risk. A total of 513 subjects were included in this study, out of which 250 were agriculture workers and 263 were non-exposed occupationally. GSTT1 and GSTM1 null genotype distribution was analyzed through multiplex-PCR method. Complete gene deletion in either of the genes was strongly associated with an increased risk (OR = 1.8; 95% CI = 1.3-2.6; p < 0.0008) of DNA/cytogenetic damage, cancer, infertility, and many other serious health effects. Therefore, homozygous deletion in GSTT1 or GSTM1 could play a modulatory role in health of workers with long-term exposure to pesticides. PMID- 29450777 TI - Recovery and characterization of proteins from pangas (Pangasius pangasius) processing waste obtained through pH shift processing. AB - Study was conducted to recover proteins from pangas (Pangasius pangasius) processing waste (fillet frames) using pH shift method and to characterize the recovered isolates. pH 2.0 from acidic range and pH 13.0 from alkaline range were found to have maximum protein recovery (p < 0.05). During the recovery process, acidic pH (pH 2.0) was found to have minimal effect on proteins resulting in more stable isolates and strong protein gels. Alkaline pH (pH 13.0) caused protein denaturation resulting in less stable proteins and poor gel network. Both acidic and alkaline-aided processing caused significant (p < 0.05) reductions in total lipid, myoglobin, and pigment content thus by resulting in whiter protein isolates and gels. The content of total essential amino acids increased during pH shift processing, indicating the enrichment of essential amino acids. No microbial counts were detected in any of the isolates prepared using acid and alkaline extraction methods. pH shift processing was found to be promising in the utilization of fish processing waste for the recovery of functional proteins from pangas processing waste thus by reducing the supply demand gap as well pollution problems. PMID- 29450778 TI - Exposure marker discovery of di(isononyl)cyclohexane-1,2-dicarboxylate using two mass spectrometry-based metabolite profiling data processing methods. AB - Di(isononyl)cyclohexane-1,2-dicarboxylate (DINCH) is a plasticizer used in polyvinyl chloride (PVC) products, such as toys and food packaging. Because the use of DINCH is on the rise, the risk of human exposure to this chemical may likewise increase. Discovering markers for assessing human chemical exposure is difficult because the metabolism of chemicals within humans is complex. In this study, two mass spectrometry (MS)-based metabolite profiling data processing methods, the mass defect filter (MDF) method and the signal mining algorithm with isotope tracing (SMAIT) method, were used for DINCH metabolite discovery, and 110 and 18 potential DINCH metabolite signal candidates were discovered, respectively, from in vitro DINCH incubation samples. Of these, the 21 signals were validated as tentative exposure marker signals in a rat model. Interestingly, the two methods generated rather different sets of DINCH exposure markers. Five of the 21 tentative exposure marker signals were verified as the probable DINCH structure-related metabolite signals based on their MS/MS product ion profiles. These five signals were detected in at least one human urine sample. Of the five probable DINCH structure-related metabolite signals, two novel signals might be suitable exposure markers that should be further investigated for their application in human DINCH exposure assessments. These observations indicate that the MDF and SMAIT methods may be used to discover a relatively different set of potential DINCH exposure markers.

AB - The paper discussed the effects of growth agents and mercury on the growth of four herb species subjected to a pot experiment: Aloe vera, Setcreasea purpurea, Chlorophytum comosum, and Oxalis corniculata. We determined the height and biomass production of selected plants treated with different growth agents and different concentrations of mercury solutions. We evaluated the relative growth rate (RGR) of the experimental plants. The aim of the study was to explore potential novel solutions to the shortcoming of the low speed of phytoremediation. The results showed that the upper parts of Aloe vera and Chlorophytum comosum had the fastest growth in the treatment with water only. In contrast, the upper parts of Setcreasea purpurea grew most intensely after the treatment with Lvyebao Fertilizer, whereas the aboveground parts of Oxalis corniculata had the fastest growth after the application of water and the occasional use of Green Cake Fertilizer. In addition, the tolerance to mercury of Oxalis corniculata was the strongest, whereas that of Chlorophytum comosum was the lowest among the species investigated.

AB - PURPOSE OF REVIEW: There has been an explosion in the number of published systematic reviews on chronic rhinosinusitis in the last decade. RECENT FINDINGS: While the aim of these reviews in facilitating evidence-based practice is laudable, poor quality reviews may contain significant bias that can mislead a non-discerning reader. Attention therefore must be given to review methodology before implanting findings. Organisations such as the Cochrane Collaboration promote high-quality reviews, but are limited in chronic sinus disease by heterogeneous outcomes and a paucity of randomised trials. PMID- 29450781 TI - Measuring Use of Evidence Based Psychotherapy for Posttraumatic Stress Disorder in a Large National Healthcare System. AB - To derive a method of identifying use of evidence-based psychotherapy (EBP) for post-traumatic stress disorder (PTSD), we used clinical note text from national Veterans Health Administration (VHA) medical records. Using natural language processing, we developed machine-learning algorithms to classify note text on a large scale in an observational study of Iraq and Afghanistan veterans with PTSD and one post-deployment psychotherapy visit by 8/5/15 (N = 255,968). PTSD visits were linked to 8.1 million psychotherapy notes. Annotators labeled 3467 randomly selected psychotherapy notes (kappa = 0.88) to indicate receipt of EBP. We met our performance targets of overall classification accuracy (0.92); 20.2% of veterans received >= one session of EBP over the study period. Our method can assist with identifying EBP use and studying EBP-associated outcomes in routine clinical practice.

In a detailed discussion with the physicians the parents decided against mechanical ventilation in the event of either acute or chronical respiratory failure. During care at home all palliative actions were taken to optimize the quality of life for the child. The boy died at the age of 7 months at home. Whether continuous mechanical ventilation in a child with spinal muscular atrophy type 1 should be the individual decision of the parents or whether it should never be offered by the physicians is discussed controversially in the present medical literature.

AB - Neuroendocrine neoplasms, including neuroendocrine tumors (NETs) and neuroendocrine carcinomas (NECs), are rare epithelial tumors with a predominant neuroendocrine differentiation. Compared with NETs, NECs have been reported to be rarer and have a poorer prognosis. We present a rare case of small bowel NEC diagnosed using double-balloon endoscopy (DBE) and the long-term survival accomplished via intensive therapy. DBE revealed an ulcerative tumor in the deep jejunum, and biopsy specimens showed large and highly dysplastic tumor cells; immuno-histological synaptophysin and chromogranin A tests were positive, and the Ki-67 index was more than 90%. Partial intestinal resection without complete lymph node dissection was performed and, postoperatively, chemotherapy was administered. The patient was observed for 3 years after chemotherapy, and complete remission was maintained. PMID- 29450788 TI - Tool use in Goffin's cockatoos: Shape/frame matching. AB - Nonhuman tool use is no longer questioned; the issues now are whether such use is mostly inflexible and innately specified or involves experience, innovation, adaptation, and cognitive planning, and how many species qualify. Habl and Auersperg (PLoS One, 12(11):e0186859, 2017) have shown that some Goffin's cockatoos (Cacatua goffiniana) respond in novel ways to a tool-use task that nonhuman primates and young children find somewhat challenging. PMID- 29450789 TI - Control by association: Transfer of implicitly primed attentional states across linked stimuli. AB - Although cognitive control has traditionally been viewed in opposition to associative learning, recent studies show that people can learn to link particular stimuli with specific cognitive control states (e.g., high attentional selectivity). Here, we tested whether such learned stimulus-control associations can transfer across paired-associates. In the Stimulus-Stimulus (S-S) Association phase, specific face or house images repeatedly preceded the presentation of particular scene stimuli, creating paired face/house-scene associates in memory. The Stimulus-Control (S-C) Association phase then associated these scenes with different attentional control states by probabilistically biasing specific scenes to mostly precede either congruent or incongruent trials in a Stroop task. Finally, in the Stimulus-Control Transfer (S-CT) phase, the faces and houses from the S-S phase preceded Stroop trials but were not predictive of congruency, testing whether stimulus-control associations would transfer from scenes to their associated face/house stimuli. In Experiments 1 and 3, we found that learned implicit stimulus-control associations could transfer across closely linked cues, and in Experiment 2, we showed that this transfer depended on the memory associations formed in the S-S phase. While this form of transfer learning has previously been demonstrated for stimulus-reward associations, the present study provides the first evidence for the associative transfer of stimulus-control associations across arbitrarily linked stimuli. This work demonstrates how people can learn to implicitly adapt their processing strategies in a flexible context dependent manner and establishes a novel learning mechanism supporting the generalization of cognitive control.

AB - The complement system (CS) has recently been recognized as a bridge between innate and adaptive immunity that constitutes a very complex mechanism controlling the clearance of pathogens, cellular debris, and immune complexes. Out of three known pathways of complement activation, the alternative pathway (AP) plays a critical role in host defense by amplifying the complement response, independently of initiation pathway and continuously maintaining low-level activity in a process called 'thick-over.' A key molecule of the CS is C3, in which the AP is constantly activated. To prevent host cell destruction, a group of the AP regulators tightly controls this pathway of the CS activation. Acquired and genetic abnormalities of the CS may alter the delicate balance between enhancing and inhibiting the AP cascade. These can lead to the uncontrolled CS activation, inflammatory response, and subsequent tissue damage. Since complement components are locally produced and activated in the kidney, the abnormalities targeting the AP may cause glomerular injury. C3 glomerulopathy is a new entity, in which the AP dysregulation has been well established. However, recent studies indicate that the AP may also contribute to a wide range of kidney pathologies, including immune-complex-mediated glomerulonephritis (GN), pauci-immune GN, and primary membranous nephropathy (PMN). This article provides insight into current knowledge on the role of the AP in the pathogenesis of glomerular diseases, focusing mainly on various types of primary and secondary GN and PMN. PMID- 29450791 TI - Face processing skills predict faithfulness of portraits drawn by novices. AB - Individuals show astonishing variability in their face recognition abilities, and the causes and consequences of this heterogeneity are unclear. Special expertise with faces, for example in portraitists, is associated with advantages on face processing tasks, especially those involving perceptual abilities. Do face processing skills improve through practice, or does drawing skill reflect pre existing individual differences? If the latter, then the association between face processing skills and production of faithful portraits should also exist in people without practice in drawing. Two exploratory studies and one follow-up confirmatory study provide support for this hypothesis. Drawing ability of novices was predicted by their performance on face recognition tasks involving perceptual discrimination and visual short-term memory, but not by those that rely more heavily on long-term memory or memory for non-face objects. By examining non-experts, we show that expertise with faces might build upon pre existing individual differences in face processing skills. PMID- 29450792 TI - Examination of long-term visual memorization capacity in the Clark's nutcracker (Nucifraga columbiana). AB - Clark's nutcrackers exhibit remarkable cache recovery behavior, remembering thousands of seed locations over the winter. No direct laboratory test of their visual memory capacity, however, has yet been performed. Here, two nutcrackers were tested in an operant procedure used to measure different species' visual memory capacities. The nutcrackers were incrementally tested with an ever expanding pool of pictorial stimuli in a two-alternative discrimination task. Each picture was randomly assigned to either a right or a left choice response, forcing the nutcrackers to memorize each picture-response association. The nutcrackers' visual memorization capacity was estimated at a little over 500 pictures, and the testing suggested effects of primacy, recency, and memory decay over time. The size of this long-term visual memory was less than the approximately 800-picture capacity established for pigeons. These results support the hypothesis that nutcrackers' spatial memory is a specialized adaptation tied to their natural history of food-caching and recovery, and not to a larger long term, general memory capacity. Furthermore, despite millennia of separate and divergent evolution, the mechanisms of visual information retention seem to reflect common memory systems of differing capacities across the different species tested in this design. PMID- 29450793 TI - The Quality of Response Time Data Inference: A Blinded, Collaborative Assessment of the Validity of Cognitive Models. AB - Most data analyses rely on models. To complement statistical models, psychologists have developed cognitive models, which translate observed variables into psychologically interesting constructs. Response time models, in particular, assume that response time and accuracy are the observed expression of latent variables including 1) ease of processing, 2) response caution, 3) response bias, and 4) non-decision time. Inferences about these psychological factors hinge upon the validity of the models' parameters. Here, we use a blinded, collaborative approach to assess the validity of such model-based inferences. Seventeen teams of researchers analyzed the same 14 data sets. In each of these two-condition data sets, we manipulated properties of participants' behavior in a two alternative forced choice task. The contributing teams were blind to the manipulations, and had to infer what aspect of behavior was changed using their method of choice. The contributors chose to employ a variety of models, estimation methods, and inference procedures. Our results show that, although conclusions were similar across different methods, these "modeler's degrees of freedom" did affect their inferences. Interestingly, many of the simpler approaches yielded as robust and accurate inferences as the more complex methods. We recommend that, in general, cognitive models become a typical analysis tool for response time data. In particular, we argue that the simpler models and procedures are sufficient for standard experimental designs. We finish by outlining situations in which more complicated models and methods may be necessary, and discuss potential pitfalls when interpreting the output from response time models. PMID- 29450794 TI - Association Between Obstetric Provider's Advice and Gestational Weight Gain. AB - Objective This study examined associations between pregnant women's report of obstetric provider GWG advice, self-reported adherence to such advice, and GWG. Methods Healthy pregnant women (N = 91) who started obstetric care prior to 17 weeks of gestation completed assessments between 30 and 34 weeks of gestation. These included survey (questions on receipt of and adherence to provider GWG advice, and demographics) and anthropometric measures. GWG data were abstracted from electronic health records. Analyses included Chi square and Mann-Whitney tests, and binary and multivariate logistic regressions. Results The cohort's median age was 28 years, 68% of women were White, 78% had a college education, 50.5% were overweight or obese before the pregnancy, and 62.6% had GWGs above the Institute of Medicine-recommended ranges. Sixty-seven percent of women reported having received GWG advice from their obstetric providers and, of those, 54.1% reported that they followed their provider's advice. Controlling for race, education and pre-pregnancy BMI, receipt of GWG advice was marginally associated with increased odds of excessive weight gain (OR 2.52, CI 0.89-7.16). However, women that reported following the advice had lower odds of excessive GWG (OR 0.18, CI 0.03-0.91) and, on average, gained 11.3 pounds less than those who reported following the advice somewhat or not at all. Conclusions Frequency of GWG advice from obstetric providers is less than optimal. When given and followed, provider advice may reduce the risk of excessive GWG. Research to understand factors that facilitate providers GWG advice giving and women's adherence to providers' advice, and to develop interventions to optimize both, is needed.

AB - The purpose of the current study was to examine the relative utility of the most updated MMPI adult instrument, the Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF), which was designed to address psychometric limitations of the MMPI-2. To this end, we compared mean scores and correlates of emotional distress treatment outcomes using the Depression Anxiety Stress Scales in a sample of 230 patients (73 males, 157 females) who had completed an interdisciplinary chronic pain rehabilitation program. Structural equation modeling analyses indicated that higher scale scores from all the MMPI-2-RF substantive domains were meaningfully associated with worse emotional distress outcomes, whereas the MMPI-2 Clinical Scales generally did not have any meaningful associations. Similar results were found in additional analyses using a clinically significant change framework with more direct clinical implications. The results of this study provide preliminary support for the use of the MMPI-2 RF among patients with chronic low back pain. PMID- 29450797 TI - Cultural Considerations for Psychologists in Primary Care. AB - Many health concerns in the United States (e.g., diabetes) are routinely managed in primary care settings. Regardless of the medical condition, patients' health is directly influenced by factors such as healthcare providers and cultural background. Training related to how behaviors influence health, coupled with training on how cultural diversity intersects with mental health, allows psychologists to have the relevant expertise to assist in the development of primary care behavioral health interventions. However, many psychologists in primary care struggle with how to integrate a culture-centered paradigm into their roles as behavioral health providers. This paper provides an introduction on how three culture-centered concepts (providers' cultural sensitivity, patient provider cultural congruency, and patients' health literacy) can be applied in primary care using the Five A's Organizational Construct and a model of cultural competence. In addition, the paper includes a section on integration of cultural considerations into consultation and training and concludes with a discussion of how the three culture-centered concepts have implications for health equity.

AB - Mesenchymal stem cells (MSCs) have shown promising outcomes in cardiac and neuronal diseases. Efficient and noninvasive tracking of MSCs is essential to harness their therapeutic potential. Iron oxide nanoparticles (IONPs) have emerged as effective means to label stem cells and visualize them using magnetic resonance imaging (MRI). It is known that IONPs do not affect viability and cell proliferation of stem cells. However, very few studies have demonstrated differentiation potential of iron oxide-labeled MSCs and their differentiation into specific lineages that can contribute to cellular therapies. The differentiation of IONP-labeled human bone marrow mesenchymal stem cells (hBM MSCs) into cardiac and neuronal lineages has never been studied. In this study, we have shown that IONP-labeled hBM-MSCs retain their differentiation potential to cardiac and neuronal cell lineages. We also confirmed that labeling hBM-MSCs with IONP does not affect their characteristic properties such as viability, cellular proliferation rate, surface marker profiling, and trilineage differentiation capacity. This study shows that IONP can be efficiently tracked, and its labeling does not alter stemness and differentiation potential of hBM MSCs. Thus, the labeled hBM-MSCs can be used in clinical therapies and regenerative medicine.

AB - Catastrophizing, acceptance, and coping have an important predictive value in chronic pain; however, it is not known which of these variables has the greatest contribution in fibromyalgia (FM). This study explored the mediating role of catastrophizing, acceptance, and coping in the relationship between pain and emotional distress/disability in a FM sample. Ninety-two FM patients and 51 healthy participants controls were evaluated on pain- and psychological-related variables. Catastrophizing, acceptance, behavioral coping, and emotional coping were significantly correlated with emotional distress and/or disability. Catastrophizing had a significant effect as a mediator on the relationship between pain and depression/anxiety. The current management of FM could improve by including cognitive techniques aimed at modifying the negative appraisal of pain. PMID- 29450800 TI - The endogenous subcellular localisations of the long chain fatty acid-activating enzymes ACSL3 and ACSL4 in sarcoma and breast cancer cells. AB - Fatty acid uptake and metabolism are often dysregulated in cancer cells. Fatty acid activation is a critical step that allows these biomolecules to enter cellular metabolic pathways such as mitochondrial beta-oxidation for ATP generation or the lipogenic routes that generate bioactive lipids such as the inositol phospholipids. Fatty acid activation by the addition of coenzyme A is catalysed by a family of enzymes called the acyl CoA synthetase ligases (ACSL). Furthermore, enhanced expression of particular ACSL isoforms, such as ACSL4, is a feature of some more aggressive cancers and may contribute to the oncogenic phenotype. This study focuses on ACSL3 and ACSL4, closely related structural homologues that preferentially activate palmitate and arachidonate fatty acids, respectively. In this study, immunohistochemical screening of multiple soft tissue tumour arrays revealed that ACSL3 and ACSL4 were highly, but differentially, expressed in a subset of leiomyosarcomas, fibrosarcomas and rhabdomyosarcomas, with consistent cytoplasmic and granular stainings of tumour cells. The intracellular localisations of endogenously expressed ACSL3 and ACSL4 were further investigated by detailed subcellular fractionation analyses of HT1080 fibrosarcoma and MCF-7 breast cancer cells. ACSL3 distribution closely overlapped with proteins involved in trafficking from the trans-Golgi network and endosomes. In contrast, the ACSL4 localisation pattern more closely followed that of calnexin which is an endoplasmic reticulum resident chaperone. Confocal immunofluorescence imaging of MCF-7 cells confirmed the intracellular localisations of both enzymes. These observations reveal new information regarding the compartmentation of fatty acid metabolism in cancer cells. PMID- 29450801 TI - Enhancement of pain inhibition by working memory with anodal transcranial direct current stimulation of the left dorsolateral prefrontal cortex. AB - The aim of this study was to examine whether transcranial direct current stimulation (tDCS) of the dorsolateral prefrontal cortex (DLPFC) enhances pain inhibition by improving working memory (WM). Forty healthy volunteers participated in two tDCS sessions. Pain was evoked by electrical stimulation at the ankle. Participants performed an n-back task (0-back and 2-back). The experimental protocol comprised five counterbalanced conditions (0-back, 2-back, pain, 0-back with pain and 2-back with pain) that were performed twice (pre-tDCS baseline and during tDCS). Compared with the pre-tDCS baseline values, anodal tDCS decreased response times for the 2-back condition (p < 0.01) but not for the 0-back condition (p > 0.5). Anodal tDCS also decreased pain ratings marginally in the 2-back with pain condition, but not the 0-back with pain condition (p = 0.052 and p > 0.2, respectively). No effect was produced by sham tDCS for any condition (p > 0.2). These results indicate that tDCS of the left DLPFC may enhance pain inhibition by improving WM.

AB - PURPOSE: Paclitaxel (PTX) loaded hydrophobically modified glycol chitosan (HGC) micelle is biocompatible in nature, but it requires cancer targeting ability and stimuli release property for better efficiency. To improve tumor retention and drug release characteristic of HGC-PTX nanomicelles, we conjugated cancer targeting heptamethine dye, MHI-148, which acts as an optical imaging agent, targeting moiety and also trigger on-demand drug release on application of NIR 808 nm laser. PROCEDURES: The amine group of glycol chitosan modified with hydrophobic 5beta-cholanic acid and the carboxyl group of MHI-148 were bonded by 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide/N-hydroxysuccinimide chemistry. Paclitaxel was loaded to MHI-HGC nanomicelle by an oil-in-water emulsion method, thereby forming MHI-HGC-PTX. RESULTS: Comparison of near infrared (NIR) dyes, MHI 148, and Flamma-774 conjugated to HGC showed higher accumulation for MHI-HGC in 4T1 tumor and 4T1 tumor spheroid. In vitro studies showed high accumulation of MHI-HGC-PTX in 4T1 and SCC7 cancer cell lines compared to NIH3T3 cell line. In vivo fluorescence imaging of the 4T1 and SCC7 tumor showed peak accumulation of MHI-HGC-PTX at day 1 and elimination from the body at day 6. MHI-HGC-PTX showed good photothermal heating ability (50.3 degrees C), even at a low concentration of 33 MUg/ml in 1 W/cm2 808 nm laser at 1 min time point. Tumor reduction studies in BALB/c nude mice with SCC7 tumor showed marked reduction in MHI-HGC-PTX in the PTT group combined with photothermal therapy compared to MHI-HGC-PTX in the group without PTT. CONCLUSION: MHI-HGC-PTX is a cancer theranostic agent with cancer targeting and optical imaging capability. Our studies also showed that it has cancer targeting property independent of tumor type and tumor reduction property by combined photothermal and chemotherapeutic effects. PMID- 29450803 TI - A rare case of acute presentation of trocar site hernia from robot-assisted laparoscopic partial nephrectomy. AB - Trocar site hernia is not a common acute complication encountered after robot assisted surgery, especially in the urological cohort of patients. A few case reports of small bowel obstruction secondary to incarceration by trocar site hernia have been described in gynaecological surgery and prostatectomies. As the clinical presentation is non-specific, late diagnosis has significant implication on morbidity and mortality. Here, we present a rare case of a patient with recent robot-assisted laparoscopic partial nephrectomy for a renal cell carcinoma presented with features of impending bowel obstruction secondary to incarcerated small bowel in the trocar site. We also reviewed the literature focusing on clinical features of trocar site hernia and preventive measures. PMID- 29450805 TI - pH-responsive CAP-co-poly(methacrylic acid)-based hydrogel as an efficient platform for controlled gastrointestinal delivery: fabrication, characterization, in vitro and in vivo toxicity evaluation. AB - Cellulose acetate phthalate-based pH-responsive hydrogel was synthesized for fabrication of polymeric matrix tablets for gastro-protective delivery of loxoprofen sodium. Cellulose acetate phthalate (CAP) was cross-linked with methacrylic acid (MAA) using free radical polymerization technique. Fourier transform infrared (FTIR) spectra confirmed the formation of cross-linked structure of CAP-co-poly(methacrylic acid). Thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) confirmed the thermal stability of polymeric networks, and scanning electron microscopy (SEM) and energy-dispersive X-ray spectrum (EDS) images unveiled that the prepared formulations were porous in nature and thus the developed formulations had shown better diffusibility. Swelling and in vitro drug release was performed at various pHs and maximum swelling and release was obtained at pH 7.4, while swelling and release rate was very low at pH 1.2 which confirmed the pH-responsive behavior of CAP-co poly(MAA). CAP-co-poly(MAA) copolymer prevents the release of loxoprofen sodium into the stomach due to reduced swelling at gastric pH while showing significant swelling and drug release in the colon. Cytotoxicity studies revealed higher biocompatibility of fabricated hydrogel. Acute oral toxicity studies were performed for the evaluation and preliminary screening of safety profile of the developed hydrogels. Matrix tablets were evaluated for release behavior at simulated body pH. The investigations performed for analysis of hydrogels and fabricated matrix tablets indicated the controlled drug release and gastro protective drug delivery of CAP-co-poly(MAA) hydrogels and pH-sensitive matrix tablets for targeted delivery of gastro-sensitive/irritative agents. Graphical abstract ?. PMID- 29450804 TI - Long-Term Development of Embryonic Cerebellar Grafts in Two Strains of Lurcher Mice. AB - For many degenerative cerebellar diseases, currently, no effective treatment that would substantially restore cerebellar functions is available. Neurotransplantation could be a promising therapy for such cases. Nevertheless, there are still severe limitations for routine clinical use. The aim of the work was to assess volume and morphology and functional impact on motor skills of an embryonic cerebellar graft injected in the form of cell suspension in Lurcher mutant and wild-type mice of the B6CBA and C3H strains after a 6-month survival period. The grafts survived in the majority of the mice. In both B6CBA and C3H Lurcher mice, most of the grafts were strictly delimited with no tendency to invade the host cerebellum, while in wild-type mice, graft-derived Purkinje cells colonized the host's cerebellum. In C3H Lurcher mice, but not in B6CBA Lurchers, the grafts had smaller volume than in their wild-type counterparts. C3H wild-type mice had significantly larger grafts than B6CBA wild-type mice. No positive effect of the transplantation on performance in the rotarod test was observed. The findings suggest that the niche of the Lurcher mutant cerebellum has a negative impact on integration of grafted cells. This factor seems to be limiting for specific functional effects of the transplantation therapy in this mouse model of cerebellar degeneration. PMID- 29450807 TI - An Eye Fixation-Related Potential Study in Two Reading Tasks: Reading to Memorize and Reading to Make a Decision. AB - We investigated how two different reading tasks, namely reading to memorize [Read & Memorize (RM)] and reading to decide whether a text was relevant to a given topic [Read & Decide (RD)], modulated both eye movements (EM) and brain activity. To this end, we set up an ecological paradigm using the eye fixation-related potentials (EFRP) technique, in which participants freely moved their eyes to process short paragraphs, while their electroencephalography (EEG) activity was recorded in synchronization with their EM. A general linear model was used to estimate at best EFRP, taking account of the overlap between adjacent potentials, and more precisely with the potential elicited at text onset, as well as saccadic potentials. Our results showed that EM patterns were top-down modulated by different task demands. More interestingly, in both tasks, we observed slow-wave potentials that gradually increased across the first eye fixations. These slow waves were larger in the RD task than in the RM task, specifically over the left hemisphere. These results suggest that the decision-making process during reading in the RD task engendered a greater memory load in working memory than that generated in a classic reading task. The significance of these findings is discussed in the light of recent theories and models of working memory processing. PMID- 29450806 TI - Dissolution and oral bioavailability enhancement of praziquantel by solid dispersions. AB - The aim of the present investigation was to enhance the solubility, dissolution, and oral bioavailability of praziquantel (PZQ), a poorly water-soluble BCS II drug (Biopharmaceutical Classification System), using a solid dispersion (SD) technique involving hydrophilic copolymers. The SD formulations were prepared by a solvent evaporation method with PZQ and PEG 4000 (polyethylene glycol 4000), PEG 6000, or P 188 polymers at various weight ratios or a combination of PEG 4000/P 188. The optimized SD formulation, which had the highest solubility in distilled water, was further characterized by its surface morphology, crystallinity, and dissolution in 0.1 M HCl with 0.2% w/v of sodium dodecyl sulfate (SDS). X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) revealed the amorphous form of PZQ in the SDs. Moreover, at an oral dosage of 5 mg/kg PZQ, the SDs had higher Cmax values and areas under the curve (AUCs) compared to those of commercial PZQ tablets. Preparation of PZQ loaded SDs using PEG 4000/P 188 is a promising strategy to improve the oral bioavailability of PZQ. PMID- 29450808 TI - Localizing Event-Related Potentials Using Multi-source Minimum Variance Beamformers: A Validation Study. AB - Adaptive and non-adaptive beamformers have become a prominent neuroimaging tool for localizing neural sources of electroencephalographic (EEG) and magnetoencephalographic (MEG) data. In this study, we investigated single-source and multi-source scalar beamformers with respect to their performances in localizing and reconstructing source activity for simulated and real EEG data. We compared a new multi-source search approach (multi-step iterative approach; MIA) to our previous multi-source search approach (single-step iterative approach; SIA) and a single-source search approach (single-step peak approach; SPA). In order to compare performances across these beamformer approaches, we manipulated various simulated source parameters, such as the amount of signal-to-noise ratio (0.1-0.9), inter-source correlations (0.3-0.9), number of simultaneously active sources (2-8), and source locations. Results showed that localization performance followed the order of MIA > SIA > SPA regardless of the number of sources, source correlations, and single-to-noise ratios. In addition, SIA and MIA were significantly better than SPA at localizing four or more sources. Moreover, MIA was better than SIA and SPA at identifying the true source locations when signal characteristics were at their poorest. Source waveform reconstructions were similar between MIA and SIA but were significantly better than that for SPA. A similar trend was also found when applying these beamformer approaches to a real EEG dataset. Based on our findings, we conclude that multi-source beamformers (MIA and SIA) are an improvement over single-source beamformers for localizing EEG. Importantly, our new search method, MIA, had better localization performance, localization precision, and source waveform reconstruction as compared to SIA or SPA. We therefore recommend its use for improved source localization and waveform reconstruction of event-related potentials. PMID- 29450809 TI - Model diagnostics for the proportional hazards model with length-biased data. AB - Length-biased data are frequently encountered in prevalent cohort studies. Many statistical methods have been developed to estimate the covariate effects on the survival outcomes arising from such data while properly adjusting for length biased sampling. Among them, regression methods based on the proportional hazards model have been widely adopted. However, little work has focused on checking the proportional hazards model assumptions with length-biased data, which is essential to ensure the validity of inference. In this article, we propose a statistical tool for testing the assumed functional form of covariates and the proportional hazards assumption graphically and analytically under the setting of length-biased sampling, through a general class of multiparameter stochastic processes. The finite sample performance is examined through simulation studies, and the proposed methods are illustrated with the data from a cohort study of dementia in Canada. PMID- 29450810 TI - Characterisation of a new species of Trichodorus Cobb, 1913 (Triplonchida: Trichodoridae) from Iran based on morphological and molecular data. AB - Trichodorus zanjanensis n. sp., collected from the rhizosphere of wild almond tree (Amygdalus scoparia Spach) in Zanjan Province, Iran, is described and illustrated based on morphological and molecular data. The new species is characterised by its body length (772-819 MUm in males; 704-953 MUm in females), and in having medium-sized onchiostyle (60-64 MUm in males; 59-65 MUm in females) and a short dorsal overlap of the intestine. Males of the new species have two ventromedian cervical papillae posterior to onchiostyle region, ventrally curved spicules, smooth, long and wide manubrium, gradually continuing in a narrower anterior part of the blade provided with bristles and marked from the wider and transversely striated main part of the blade, tapered towards distal end, three ventromedian precloacal supplements, the posterior one (SP1) situated at the level of anterior blade and gubernaculum situated at 24-25 MUm from the cloaca. Females have one pair of sublateral body pores in the vulva region, medium rounded triangular to oval sclerotised vaginal pieces in lateral view, and pear shaped vagina. The new species resembles T. persicus De Waele & Sturhan, 1987, T. minzi De Waele & Cohn, 1992 and T. taylori De Waele, Mancini, Roca & Lamberti, 1982. The results of morphological and morphometric comparisons and molecular data based on sequences of the partial 18S and D2-D3 expansion segments of 28S rRNA genes, clearly separated T. zanjanensis n. sp. from these known species and supported the description of T. zanjanensis n. sp. as a new species. PMID- 29450811 TI - Debulking surgery of pituitary adenoma as a strategy to facilitate definitive stereotactic radiosurgery. AB - In patients with pituitary adenomas (PA) who are unable to undergo complete surgical resection, radiation therapy (RT), specifically stereotactic radiosurgery (SRS), results in excellent local control. However, the utility of radiosurgery may be limited by the proximity of the lesion to the optic chiasm (OC). We evaluate the efficacy of debulking surgery in increasing the PA-OC separation to convert patients into SRS candidates. From 2007 to 2015, 31 patients with PA < 2 mm from the OC underwent debulking surgery followed by RT within 2 years of resection. Coronal and sagittal T1-pre- and post-contrast sequences were used to determine PA-OC separation. Time interval between postoperative and pre-radiotherapy MRI scans and type of radiation therapy were analyzed. Functional tumor status, tumor characteristics [cavernous sinus (CS) or suprasellar (SS) involvement, chiasm/nerve encasement (NE)], and presence of >= 2 of these characteristics (multiple factors, MF) was also noted. Surgery converted 9 of 31 patients (29%) to SRS candidates. Median time from surgery to pre-RT planning MRI was 8 months (range 2-20). Of the 31 patients initially ineligible for SRS, 6 became eligible immediately after surgery, and another 3 were deemed eligible on follow-up. Mean PA-OC separation was 0.3 mm preoperative, 1.4 mm postoperative, and 2.1 mm at time of SRS (p = 0.002). Preoperative SS, NE, and MF involvement predicted pre-RT separation < 2 mm. Debulking surgery of unresectable pituitary tumors is a successful strategy for converting select radiosurgery ineligible patients to radiosurgery candidates. Absence of preoperative SS, NE, and MF predicts for successful conversion. PMID- 29450814 TI - Improving the Catalytic Activity and Thermostability of MAS1 Lipase by Alanine Substitution. AB - MAS1 is a lipase isolated from Streptomyces sp. strain W007 with potential application in biotechnology. Structural analysis of MAS1 lipase showed that eight amino acids with bulkier side located in the substrate-binding pocket may be involved in affecting catalytic performance. Alanine substitutions of those residues were conducted to reduce steric clash of catalyzed pocket and probe their functional roles. The kcat/Km of mutants H108A, F153A, and V233A increased to 2.3-, 2.1-, and 1.4-fold, respectively. Interestingly, the half-life (60 degrees C) of F153A had shifted to 523 min after mutagenesis, which was fivefold enhancement toward that of MAS1 wide-type. Furthermore, higher hydrolysis ability of mutants H108A and F153A toward palm stearin of high melting temperature made them potentially applicable in oil/fat modification. Our work provided an example to obtain biocatalysts with desired catalytic behaviors by protein engineering. PMID- 29450813 TI - Memory Rehabilitation in Patients with Epilepsy: a Systematic Review. AB - Memory failure is a common clinical concern of patients with epilepsy and is associated with significant functional impairments. Thus, memory rehabilitation is of critical clinical importance. In this article, we aimed to systematically evaluate the efficacy of memory rehabilitation in patients with epilepsy. The Preferred Items for Systematic Reviews and Meta-Analyses (PRISMA) was used to guide searches, extraction and reporting of data in this review. PsycINFO, Medline and PsychBITE searches yielded 95 studies. Twelve papers met inclusion criteria, reporting outcomes of cognitive or behavioural interventions that specifically targeted the rehabilitation of memory in patients with epilepsy. Methodological rigour was rated using the Single-Case Experimental Design (SCED) scale for single-case studies and a modified version of the Downs and Black checklist for group studies. Twelve prospective studies, nine group (six pre-post design, one waitlist crossover, two randomised controlled trials) and three single-case studies were identified. Eleven of the studies included adults, eight of which involved adults with temporal lobe epilepsy (TLE). One paediatric study was identified. The quality of group studies ranged from 36% (poor) to 72% (good), using the modified Downs and Black checklist. Single-case studies were assessed using the SCED scale and assessed to range in quality from four to seven out to 11. Overall, memory rehabilitation was associated with improved memory function in all studies. Verbal memory outcomes were most commonly examined and associated with improvements. This review found that the level of evidence available to support rehabilitation of memory in patients with epilepsy was generally weak and inconsistent. Nevertheless, studies conducted to date, albeit of limited methodological quality, offer preliminary evidence that memory rehabilitation is associated with improvements in verbal memory in patients with temporal lobe epilepsy. Little is known about the efficacy of memory rehabilitation in patients with non-TLE, children, and other aspects of memory difficulties. Guidelines for future research are proposed. PMID- 29450815 TI - Factors affecting reproductive performance in dromedary camel herds in Saudi Arabia. AB - A survey of 7122 dromedary camels in 115 herds in Saudi Arabia was used to estimate the effects of herd size (HZ; < 25 vs. 25-49 vs. 50-100 vs. > 100 camels), herder/camels ratio (H/C; 1:< 25 vs. 1:25-50 vs. 1:> 50), manager experience (ME; < 5 vs. 5-10 vs. > 10 years), male/females ratio (M/F), housing system (HS; free vs. closed vs. mixed), length of the breeding season (winter vs. winter and spring vs. fall, winter and spring), age at first mating (3 vs. > 3 years), and time of mating after parturition (<= 3 vs. > 3 months) and their interactions on the overall pregnancy rate. Barren females of these herds (n = 886) were examined for the causes of infertility. Results showed that herds with H/C of 1:< 25 had higher overall pregnancy rate (95.29%) than herds with H/C of 1:25-50 (79.84%) and those with H/C of 1:> 50 (72.79%) (p = 0.003). Herds having ME of > 10 years revealed greater overall pregnancy rate (94.89%) than herds with ME of 5-10 years (80.54%) and those with ME of < 5 years (72.5%) (p = 0.001). There were significant interactions between H/C * HZ (p = 0.003), H/C * HS (p = 0.006), and ME * HS (p = 0.02). The overall pregnancy rate did not significantly differ between herds bred females by age of 3 years and those bred females by age > 3 years and in females bred within 3 months after parturition and in those bred after 3 months. The mean calving interval was shorter (p = 0.008) in camels mated within 3 months of parturition (15.25 +/- 2.8 months) than in those mated after that time (24.33 +/- 6.5 months). Clinical endometritis, ovarian hydrobursitis, and vaginal adhesions were the common clinical findings in barren females. Thus, efforts to reduce the age at first mating and the interval after calving, increase the number of herders/camels, and control reproductive disorders could improve the reproductive performance and quality of camel herds in Saudi Arabia.

AB - Gliomas are the most common primary intrinsic tumor in the brain and are classified as low- or high-grade according to the World Health Organization (WHO). Patients with high-grade gliomas (HGG) who undergo surgical resection with adjuvant therapy have a mean overall survival of 15 months and 100% recurrence. The renin-angiotensin system (RAS), the primary regulator of cardiovascular circulation, exhibits local action and works as a paracrine system. In the context of this local regulation, the expression of RAS peptides and receptors has been detected in different kinds of tumors, including gliomas. The dysregulation of RAS components plays a significant role in the proliferation, angiogenesis, and invasion of these tumors, and therefore in their outcomes. The study and potential application of RAS peptides and receptors as biomarkers in gliomas could bring advantages against the limitations of current tumoral markers and should be considered in the future. The targeting of RAS components by RAS blockers has shown potential of being protective against cancer and improving immunotherapy. In gliomas, RAS blockers have shown a broad spectrum for beneficial effects and are being considered for use in treatment protocols. This review aims to summarize the background behind how RAS plays a role in gliomagenesis and explore the evidence that could lead to their use as biomarkers and treatment adjuvants. PMID- 29450817 TI - Prediction of Neonatal Hyperbilirubinemia Using 1st Day Serum Bilirubin Levels. AB - The study was conducted on Full term neonates with birth weight > 2.5 kg born in KIMS, Hubballi with an objective to determine the first day Total Serum Bilirubin (TSB) value so as to predict subsequent development of significant hyperbilirubinemia in term neonates. All enrolled neonates were sampled for TSB and blood group on Day 1 at 20 +/- 4 h and then followed up clinically by Kramer's rule and when the clinical jaundice by Kramer's rule was >10 mg/dl, TSB levels were repeated. A total of 180 newborns were enrolled for the study and 165 babies completed the study. Out of these, 17(10.3%) babies had significant hyperbilirubinemia by day 5 of life. Using Receiver Operating Characteristic (ROC) Curve, a cut off TSB value of 6.15 mg/dl was determined with sensitivity of 82.4%, specificity of 81.8%, positive predictive value of 32.8%, negative predictive value 97.6%. In term neonates, the first day total bilirubin level at 20 +/- 4 h of life <6.15 predicts the low risk of subsequent significant hyperbilirubinemia with high probability.

AB - OBJECTIVE: Familial Hypercholesterolemia (FH) is an inherited disorder of lipid metabolism characterized by very high low density lipoprotein (LDL) cholesterol since birth, resulting in premature atherosclerosis and coronary artery disease (CAD). Cascade screening of children and family members of proven FH individuals can identify more subjects who have high LDL cholesterol or the family mutation and appropriate intervention can reduce their risk of atherosclerosis and prevent its complications. METHODS: Cascade screening by molecular testing, was carried out in 133 family members, comprising 24 children, of 31 probands with FH having a pathogenic mutation in LDLR/ApoB gene. Lipid profiles were obtained in 44 family members including 11 children. RESULTS: Of 133 family members tested, 88 (66.1%) were identified to carry the family mutation. Twelve of these were children below 18 y of age and 76 were adults. CAD was present in 15 (11.2%) family members and 63(47.4%) family members, including nine children, were already on Lipid Lowering Therapy. CONCLUSIONS: Cascade screening led to identification of 88 new cases, with a pathogenic mutation, who were at a very high risk of developing premature CAD. The authors identified 12 children with family specific mutation, out of which 9 were initiated on low dose statin therapy. Four homozygous children were treated with high dose statins because of substantially increased risk of CAD. Cascade screening, therefore, proved to be a successful initiative towards primary prevention of CAD in India. PMID- 29450820 TI - Overlapping and Distinct Cognitive Impairments in Attention-Deficit/Hyperactivity and Autism Spectrum Disorder without Intellectual Disability. AB - Attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) are commonly comorbid, share genetic liability, and often exhibit overlapping cognitive impairments. Clarification of shared and distinct cognitive effects while considering comorbid symptoms across disorders has been lacking. In the current study, children ages 7-15 years assigned to three diagnostic groups:ADHD (n = 509), ASD (n = 97), and controls (n = 301) completed measures spanning the cognitive domains of attention/arousal, working memory, set shifting, inhibition, and response variability. Specific processes contributing to response variability were examined using a drift diffusion model, which separately quantified drift rate (i.e., efficiency of information processing), boundary separation (i.e., speed-accuracy trade-offs), and non-decision time. Children with ADHD and ASD were impaired on attention/arousal, processing speed, working memory, and response inhibition, but did not differ from controls on measures of delayed reward discounting, set-shifting, or interference control. Overall, impairments in the ASD group were not attributable to ADHD symptoms using either continuous symptom measures or latent categorical grouping approaches. Similarly, impairments in the ADHD group were not attributable to ASD symptoms. When specific RT parameters were considered, children with ADHD and ASD shared impairments in drift rate. However, children with ASD were uniquely characterized by a wider boundary separation. Findings suggest a combination of overlapping and unique patterns of cognitive impairment for children with ASD as compared to those with ADHD, particularly when the processes underlying reaction time measures are considered separately. PMID- 29450821 TI - Episodic Life Stress and the Development of Overgeneral Autobiographical Memory to Positive Cues in Youth. AB - Overgeneral autobiographical memory (OGM) has been established as a risk factor for depression in both youth and adults, but questions remain as to how OGM develops. Although theorists have proposed that the experience of stressful life events may contribute to the development of OGM, no studies have examined the impact of negative life events on prospective changes in OGM. The goal of the current study was to address this gap in the literature. Participants included 251 mothers and their biological children (aged 8-14 years old at the initial assessment). Using a multi-wave prospective design with assessments every 6 months for 2 years, we found that episodic life stress predicted prospective decreases in youths' autobiographical memory specificity to positive, but not negative, cues. This study supports theories proposing that negative life events may contribute to the development of OGM, but suggest that, in youth, the impact of life stress on OGM may be specific to positive rather than negative memories.

In bacteria, a large catalytic RNA and a small protein component assemble to recognize and accurately cleave ptRNA and tRNA-like molecular scaffolds. Substrate recognition of ptRNA by bacterial RNase P requires RNA-RNA shape complementarity, intermolecular base pairing, and a dynamic protein ptRNA binding interface. To gain insight into the binding specificity and dynamics of the bacterial protein-ptRNA interface, we report the backbone and side chain 1H, 13C, and 15N resonance assignments of the hyperthermophilic Thermatoga maritima RNase P protein in solution at 318 K. Our data confirm the formation of a stable RNA recognition motif (RRM) with intrinsic heterogeneity at both the N- and C-terminus of the protein, consistent with available structural information. Comprehensive resonance assignments of the bacterial RNase P protein serve as an important first step in understanding how coupled RNA binding and protein-RNA conformational changes give rise to ribonucleoprotein function.

AB - Each year, nearly 900,000 deaths are due to serious liver diseases caused by chronic hepatitis B virus infection. The viral particle is composed of an outer envelope and an inner icosahedral nucleocapsid formed by multiple dimers of a ~ 20 kDa self-assembling core protein (Cp). Here we report the solid-state 13C and 15N resonance assignments of the assembly domain, Cp149, of the core protein in its capsid form. A secondary chemical shift analysis of the 140 visible residues suggests an overall alpha-helical three-dimensional fold matching that derived for Cp149 from the X-ray crystallography of the capsid, and from solution-state NMR of the Cp149 dimer. Interestingly, however, at three distinct regions the chemical shifts in solution differ significantly between core proteins in the capsid state versus in the dimer state, strongly suggesting the respective residues to be involved in capsid assembly.

AB - BACKGROUND: Laparoscopic conversion-to-open colorectal surgery is associated with worse outcomes when compared to operations completed without conversion. Consequences of robotic conversion have not yet been determined. The purpose of this study is to compare short-term outcomes of converted robotic colorectal cases with those that are completed without conversion, as well as with cases done by the open approach. METHODS: The ACS-NSQIP database was queried for patients who underwent robotic completed, robotic converted-to-open, and open colorectal resection between 2012 and 2015. Propensity scores were estimated using gradient-boosted machines and converted to weights. Generalized linear models were fit using propensity score-weighted data. RESULTS: A total of 25,253 patients met inclusion criteria-21,356 (84.5%) open, 3663 (14.5%) robotic completed, and 234 (0.9%) conversions. Conversion rate was 6.0%. Converted cases had significantly higher 30-day mortality rate, higher complication rate, and longer hospital length of stay than completed cases. Converted patients also had significantly higher rates of the following complications: surgical site infections, cardiac complications, deep venous thrombosis, postoperative ileus, postoperative re-intubation, renal failure, and 30-day reoperation. Compared to the open approach, converted patients had significantly more cardiac complications, postoperative reintubation, and longer operating times with no significant difference in 30-day mortality. CONCLUSIONS: Unplanned robotic conversion-to-open is associated with worse outcomes than completed cases and outcomes that more closely resemble traditional open colorectal surgery. Patients should be counseled with regard to minimally invasive conversion rates and outcomes. The continued pursuit of technological advancements that decrease the risk for conversion in minimally invasive colorectal surgery is clearly warranted. PMID- 29450826 TI - Return to Throwing after Shoulder or Elbow Injury. AB - PURPOSE OF REVIEW: Throwing places high demands on the human body, and specific characteristics are developed over time unique to these athletes. When returning to throw after injury, it is important to follow a criterion-based progression that allows the body to be prepared appropriately for the stresses that throwing will require. There is currently a void in the literature for criteria-based progression that helps these athletes return to the highest level of play. RECENT FINDINGS: As injury rates continue to rise in baseball, there is increased evidence showing contributions of the core and lower extremity to the baseball pitch. There is also additional data showing pitcher specific characteristics such as range of motion and scapular position in this unique population. The rehab professional should take into account every phase of the pitch starting from balance through ball release when designing a comprehensive return-to throwing program. Returning an athlete back to a throwing sport can be an overwhelming task. The rehabilitation specialist must have a sound understanding of the throwing motion as well as any biomechanical implications on the body, contributions throughout the kinetic chain, range of motion, and strength characteristics specific to the thrower as well as proper tissue loading principles. It is important that these athletes are not progressed too quickly through their programs and that a criteria-based progression is followed. They should have normalized range of motion, strength, and scapular mechanics, followed by a sound plyometric progression. Once this is achieved, they are advanced to an interval throwing program with increasing distance, effort, and volume which should be tracked for workload, making sure they do not throw more than their body is prepared for.

AB - BACKGROUND: The international, phase III FALCON study (NCT01602380) in postmenopausal patients with hormone receptor-positive, locally advanced/metastatic breast cancer (LA/MBC) who had not received prior endocrine therapy, demonstrated statistically significant improvement in progression-free survival (PFS) for patients who received fulvestrant 500 mg vs anastrozole 1 mg. This subgroup analysis evaluated PFS in Asian (randomized in China, Japan, or Taiwan) and non-Asian patients from the FALCON study. METHODS: Eligible patients (estrogen receptor- and/or progesterone receptor-positive LA/MBC; World Health Organization performance status 0-2; >= 1 measurable/non-measurable lesion[s]) were randomized. PFS was assessed via Response Evaluation Criteria in Solid Tumours version 1.1, surgery/radiotherapy for disease worsening, or death (any cause). Secondary endpoints included: objective response rate, clinical benefit rate, duration of response, and duration of clinical benefit. Consistency of effect across subgroups was assessed via hazard ratios and 95% confidence intervals (CIs) using a log-rank test. Adverse events (AEs) were evaluated. RESULTS: Of the 462 randomized patients, the Asian and non-Asian subgroups comprised 67 and 395 patients, respectively. In the Asian subgroup, median PFS was 16.6 and 15.9 months with fulvestrant and anastrozole, respectively (hazard ratio 0.81; 95% CI 0.44-1.50). In the non-Asian subgroup, median PFS was 16.5 and 13.8 months, respectively (hazard ratio 0.79; 95% CI 0.62-1.01). Secondary outcomes were numerically improved with fulvestrant vs anastrozole in both subgroups. AE profiles were generally consistent between Asian and non-Asian subgroups. CONCLUSIONS: Results of this subgroup analysis suggest that treatment effects in the Asian patient subgroup are broadly consistent with the non-Asian population. PMID- 29450828 TI - The Role of Excipients in the Stability of Triamcinolone Acetonide in Ointments. AB - Degradation of triamcinolone acetonide (TCA) in an ointment was investigated. TCA appeared to be concentrated in propylene glycol (PG) which in turn is dispersed in a lanolin-petrolatum mixture. Two predominant degradation products were identified: a 21-aldehyde and a 17-carboxylic acid. The 21-aldehyde is formed after TCA is oxidized by O2, a reaction that is catalyzed by trace metals. Logically, the content of trace metals has a profound effect on the degradation rate. It was shown that trace metals are extracted from lanolin and petrolatum by PG, increasing the concentration in PG. In accordance with these findings, TCA degrades faster in PG that is present in the ointment formulation than in regular PG. The 21-aldehyde was confirmed to be a primary degradation product, while the 17-carboxylic acid was identified as a secondary degradation product. Based on the mechanism of degradation, the ointment can be stabilized by the addition of sodium metabisulfite which was shown to reside also in the PG phase within the ointment. PMID- 29450829 TI - Artificial Lipid Membrane Permeability Method for Predicting Intestinal Drug Transport: Probing the Determining Step in the Oral Absorption of Sulfadiazine; Influence of the Formation of Binary and Ternary Complexes with Cyclodextrins. AB - We propose an in vitro permeability assay by using a modified lipid membrane to predict the in vivo intestinal passive permeability of drugs. Two conditions were tested, one with a gradient pH (pH 5.5 donor/pH 7.4 receptor) and the other with an iso-pH 7.4. The predictability of the method was established by correlating the obtained apparent intestinal permeability coefficients (Papp) and the oral dose fraction absorbed in humans (fa) of 16 drugs with different absorption properties. The Papp values correlated well with the absorption rates under the two conditions, and the method showed high predictability and good reproducibility. On the other hand, with this method, we successfully predicted the transport characteristics of oral sulfadiazine (SDZ). Also, the tradeoff between the increase in the solubility of SDZ by its complex formation with cyclodextrins and/or aminoacids and its oral permeability was assessed. Results suggest that SDZ is transported through the gastrointestinal epithelium by passive diffusion in a pH-dependent manner. These results support the classification of SDZ as a high/low borderline permeability compound and are in agreement with the Biopharmaceutics Classification Systems (BCS). This conclusion is consistent with the in vivo pharmacokinetic properties of SDZ. PMID- 29450830 TI - Personalized Medicine and Pay for Performance: Should Pharmaceutical Firms be Fully Penalized when Treatment Fails? AB - In this article, we model the behavior of a pharmaceutical firm that has marketing authorization for a new therapy believed to be a candidate for personalized use in a subset of patients, but that lacks information as to why a response is seen only in some patients. We characterize the optimal outcome-based reimbursement policy a health authority should follow to encourage the pharmaceutical firm to undertake research and development activities to generate the information needed to effectively stratify patients. Consistent with the literature, we find that for a pharmaceutical firm that does not undertake research and development activities, when the treatment fails, the total price of the drug must be returned to the healthcare system (full penalization). By contrast, if the firm undertakes research and development activities that make the implementation of personalized medicine possible, treatment failure should not be fully penalized. Surprisingly, in some cases, particularly for high efficacy drugs and small target populations, the optimal policy may not require any penalty for treatment failure. To illustrate the main results of the analysis, we provide a numerical simulation and a graphical analysis. PMID- 29450832 TI - Perceptual Modification of the Built Environment to Influence Behavior Associated with Physical Activity: Quasi-Experimental Field Studies of a Stair Banister Illusion. AB - BACKGROUND: Re-engineering the built environment to influence behaviors associated with physical activity potentially provides an opportunity to promote healthier lifestyles at a population level. Here we present evidence from two quasi-experimental field studies in which we tested a novel, yet deceptively simple, intervention designed to alter perception of, and walking behavior associated with, stairs in an urban area. OBJECTIVES: Our objectives were to examine whether adjusting a stair banister has an influence on perceptions of stair steepness or on walking behavior when approaching the stairs. METHODS: In study 1, we asked participants (n = 143) to visually estimate the steepness of a set of stairs viewed from the top, when the stair banister was adjusted so that it converged with or diverged from the stairs (+/- 1.91 degrees ) or remained neutral (+/- 0 degrees ). In study 2, the walking behavior of participants (n = 36) was filmed as they approached the stairs to descend, unaware of whether the banister converged, diverged, or was neutral. RESULTS: In study 1, participants estimated the stairs to be steeper if the banister diverged from, rather than converged with, the stairs. The effect was greater when participants were unaware of the adjustment. In study 2, walking speed was significantly slower when the banister diverged from, rather than converged with, the stairs. CONCLUSIONS: These findings encourage us to speculate about the potential to economically re engineer features of the built environment to provide opportunities for action (affordances) that invite physical activity behavior or even promote safer navigation of the environment. PMID- 29450831 TI - Comparison of Different Strategies for Providing Fecal Microbiota Transplantation to Treat Patients with Recurrent Clostridium difficile Infection in Two English Hospitals: A Review. AB - Fecal microbiota transplant (FMT) has emerged as a highly efficacious treatment for difficult cases of refractory and/or recurrent Clostridium difficile infection (CDI). There have been many well-conducted randomized controlled trials and thousands of patients reported in case series that describe success rates of approximately 90% following one or more FMT. Although the exact mechanisms of FMT have yet to be fully elucidated, replacement or restoration of a 'normal' microbiota (or at least a microbiota resembling those who have never had CDI) appears to have a positive effect on the gut dysbiosis that is thought to exist in these patients. Furthermore, despite being aesthetically unappealing, this 'ultimate probiotic' is a particularly attractive solution to a difficult problem that avoids repeated courses of antibiotics. The lack of clarity about the exact mechanism of action and the 'active ingredient' of FMT (e.g., individual or communities of bacteria, bacteriophage, or bioactive molecules such as bile acids) has hindered the ability to produce a standardized and well-characterized FMT product. There is no standard method to produce material for FMT, and there are a multitude of factors that can vary between institutions that offer this therapy. Only a few studies have directly compared clinical efficacy in groups of patients who have been treated with FMT prepared differently (e.g., fresh vs. frozen) or administered by different route (e.g., by nasojejunal tube, colonoscopy or by oral administration of encapsulated product). More of these studies should be undertaken to clarify the superiority or otherwise of these variables. This review describes the methods and protocols that two English NHS hospitals independently adopted over the same time period to provide FMT for patients with recurrent CDI. There are several fundamental differences in the methods used, including selection and testing of donors, procedures for preparation and storage of material, and route of administration. These methods are described in detail in this review highlighting differing practice. Despite these significant methodological variations, clinical outcomes in terms of cure rate appear to be remarkably similar for both FMT providers. Although both hospitals have treated only modest numbers of patients, these findings suggest that many of the described differences may not be critical factors in influencing the success of the procedure. As FMT is increasingly being proposed for a number of conditions other than CDI, harmonization of methods and techniques may be more critical to the success of FMT, and thus it will be important to standardize these as far as practically possible. PMID- 29450833 TI - Assessing the Importance of Treatment Goals in Patients with Psoriasis: Analytic Hierarchy Process vs. Likert Scales. AB - BACKGROUND: To define treatment benefit, the Patient Benefit Index contains a weighting of patient-relevant treatment goals using the Patient Needs Questionnaire, which includes a 5-point Likert scale ranging from 0 ("not important at all") to 4 ("very important"). These treatment goals have been assigned to five health dimensions. The importance of each dimension can be derived by averaging the importance ratings on the Likert scales of associated treatment goals. OBJECTIVE: As the use of a Likert scale does not allow for a relative assessment of importance, the objective of this study was to estimate relative importance weights for health dimensions and associated treatment goals in patients with psoriasis by using the analytic hierarchy process and to compare these weights with the weights resulting from the Patient Needs Questionnaire. Furthermore, patients' judgments on the difficulty of the methods were investigated. METHODS: Dimensions of the Patient Benefit Index and their treatment goals were mapped into a hierarchy of criteria and sub-criteria to develop the analytic hierarchy process questionnaire. Adult patients with psoriasis starting a new anti-psoriatic therapy in the outpatient clinic of the Institute for Health Services Research in Dermatology and Nursing at the University Medical Center Hamburg (Germany) were recruited and completed both methods (analytic hierarchy process, Patient Needs Questionnaire). Ratings of treatment goals on the Likert scales (Patient Needs Questionnaire) were summarized within each dimension to assess the importance of the respective health dimension/criterion. Following the analytic hierarchy process approach, consistency in judgments was assessed using a standardized measurement (consistency ratio). RESULTS: At the analytic hierarchy process level of criteria, 78 of 140 patients achieved the accepted consistency. Using the analytic hierarchy process, the dimension "improvement of physical functioning" was most important, followed by "improvement of social functioning". Concerning the Patient Needs Questionnaire results, these dimensions were ranked in second and fifth position, whereas "strengthening of confidence in the therapy and in a possible healing" was ranked most important, which was least important in the analytic hierarchy process ranking. In both methods, "improvement of psychological well-being" and "reduction of impairments due to therapy" were equally ranked in positions three and four. In contrast to this, on the level of sub-criteria, predominantly a similar ranking of treatment goals could be observed between the analytic hierarchy process and the Patient Needs Questionnaire. From the patients' point of view, the Likert scales (Patient Needs Questionnaire) were easier to complete than the analytic hierarchy process pairwise comparisons. CONCLUSIONS: Patients with psoriasis assign different importance to health dimensions and associated treatment goals. In choosing a method to assess the importance of health dimensions and/or treatment goals, it needs to be considered that resulting importance weights may differ in dependence on the used method. However, in this study, observed discrepancies in importance weights of the health dimensions were most likely caused by the different methodological approaches focusing on treatment goals to assess the importance of health dimensions on the one hand (Patient Needs Questionnaire) or directly assessing health dimensions on the other hand (analytic hierarchy process).

AB - Allied health professionals (AHPs) are trusted sources of information and intervention for clients with autism spectrum disorder. However, the level of implementation of empirically-supported therapies and the accuracy of the knowledge they use to inform intervention selection is largely unknown. The present study explored the accuracy of AHPs' knowledge and use of practices, and explored links to individual attitudes and organisational culture. Overall results from the 156 AHPs surveyed suggested general accuracy of knowledge, and use of empirically supported treatments, with accuracy linked to use. Use of practices unsupported by research was linked to organisational culture and openness to new interventions. The presence of misinformation and the impact on selection and use of effective practices are discussed.

AB - The ratio of the index (2nd) finger to ring (4th) finger lengths (2D:4D) is a proxy for fetal testosterone and estradiol. Studies suggesting 2D:4D is inversely associated with autism spectrum disorder (ASD) in males were limited by lack of confounder and subgroup assessments. Studies of females are sparse. We examined associations between ASD and 2D:4D among children in the Study to Explore Early Development; we considered case subgroups and numerous potential demographic and maternal-perinatal health confounders. We observed a modest inverse association between ASD and right-hand 2D:4D in males; subgroup analyses indicated associations were limited to ASD cases with birth defects/genetic syndromes or dysmorphic features. We observed a positive association between ASD and left-hand 2D:4D in females, overall and within most case subgroups.

AB - Children with autism spectrum disorder (ASD) are at high risk for being overweight and obese. Little is known about how obesity in children with ASD is being addressed in primary care. This article reports findings from a survey completed by 327 general pediatricians, which included a fictional clinical vignette and Likert-scales assessing attitudes, practices, self-efficacy, and barriers to obesity management. Although the majority of respondents agreed pediatricians should be the main providers to manage obesity in children with ASD, few reported receiving adequate training to do so. Pediatricians were more likely to refer to developmental-behavioral pediatricians and dietitians for a child with ASD compared to a child without ASD. Higher self-efficacy was associated with increased weight-related counseling frequency by pediatricians. PMID- 29450839 TI - Characterizing Health Disparities in the Age of Autism Diagnosis in a Study of 8 Year-Old Children. AB - The diagnosis of autism spectrum disorder (ASD) is often delayed from the time of noted concerns to the actual diagnosis. The current study used child- and family level factors to identify homogeneous classes in a surveillance-based sample (n = 2303) of 8-year-old children with ASD. Using latent class analysis, a 5-class model emerged and the class memberships were examined in relation to the child's median age at ASD diagnosis. Class 3, with known language delays and a high advantage socioeconomically had the lowest age of ASD diagnosis (46.74 months) in comparison to Classes 1 (64.99 months), 4 (58.14 months), and 5 (69.78 months) in this sample. Findings demonstrate sociodemographic and developmental disparities related to the age at ASD diagnosis.

AB - OBJECTIVES: Resident and fellow physicians are at elevated risk for developing depression compared to the general population; however, they are also less likely to utilize mental health services. We sought to identify the barriers to seeking mental health treatment among residents across all specialties at a large academic medical center in Chicago, IL. METHODS: Residents and fellows from all programs were asked to complete an anonymous self-report questionnaire. RESULTS: Of the 18% of residents and fellows that completed the survey, 61% felt they would have benefited from psychiatric services. Only 24% of those who felt they needed care actually sought treatment. The most commonly reported barriers to seeking care were lack of time (77%), concerns about confidentiality (67%), concerns about what others would think (58%), cost (56%), and concern for effect on one's ability to obtain licensure (50%). CONCLUSIONS: Despite feeling that they require mental health services, few trainees actually sought care. This study identifies an overall need for improved access to mental health providers and psychoeducation for medical housestaff. PMID- 29450841 TI - Differential Binding of Human ApoE Isoforms to Insulin Receptor is Associated with Aberrant Insulin Signaling in AD Brain Samples. AB - Apolipoprotein E4 (ApoE4) is the strongest genetic risk factor for sporadic Alzheimer's disease (AD), where inheritance of this isoform predisposes development of AD in a gene dose-dependent manner. Although the mode of action of ApoE4 on AD onset and progression remains unknown, we have previously shown that ApoE4, and not ApoE3 expression, resulted in insulin signaling deficits in the presence of amyloid beta (Abeta). However, these reports were not conducted with clinical samples that more accurately reflect human disease. In this study, we investigated the effect of ApoE genotype on the insulin signaling pathway in control and AD human brain samples. We found that targets of the insulin signaling pathway were attenuated in AD cases, regardless of ApoE isoform. We also found a decrease in GluR1 subunit expression, and an increase NR2B subunit expression in AD cases, regardless of ApoE isoform. Lastly, we observed that more insulin receptor (IR) was immunoprecipitated in control cases, and more Abeta was immunoprecipitated with AD cases. But, when comparing among AD cases, we found that more IR was immunoprecipitated with ApoE3 than ApoE4, and more Abeta was immunoprecipitated with ApoE4 than ApoE3. Our results suggest that the difference in IR binding and effect on protein expression downstream of the IR may affect onset and progression of AD. PMID- 29450843 TI - Detection of Lung Contour with Closed Principal Curve and Machine Learning. AB - Radiation therapy plays an essential role in the treatment of cancer. In radiation therapy, the ideal radiation doses are delivered to the observed tumor while not affecting neighboring normal tissues. In three-dimensional computed tomography (3D-CT) scans, the contours of tumors and organs-at-risk (OARs) are often manually delineated by radiologists. The task is complicated and time consuming, and the manually delineated results will be variable from different radiologists. We propose a semi-supervised contour detection algorithm, which firstly uses a few points of region of interest (ROI) as an approximate initialization. Then the data sequences are achieved by the closed polygonal line (CPL) algorithm, where the data sequences consist of the ordered projection indexes and the corresponding initial points. Finally, the smooth lung contour can be obtained, when the data sequences are trained by the backpropagation neural network model (BNNM). We use the private clinical dataset and the public Lung Image Database Consortium and Image Database Resource Initiative (LIDC-IDRI) dataset to measure the accuracy of the presented method, respectively. To the private dataset, experimental results on the initial points which are as low as 15% of the manually delineated points show that the Dice coefficient reaches up to 0.95 and the global error is as low as 1.47 * 10-2. The performance of the proposed algorithm is also better than the cubic spline interpolation (CSI) algorithm. While on the public LIDC-IDRI dataset, our method achieves superior segmentation performance with average Dice of 0.83. PMID- 29450844 TI - EndoBarrier(r): a Safe and Effective Novel Treatment for Obesity and Type 2 Diabetes? AB - BACKGROUND AND AIMS: Obesity associated with diabetes mellitus is a significant worldwide problem associated with considerable health care costs. Whilst surgical intervention is effective, it is invasive, costly and associated with complications. This study aims to evaluate the safety and efficacy of the EndoBarrier(r), a duodenal-jejunal sleeve bypass as an alternative treatment of diabetes mellitus in obese patients. MATERIALS AND METHODS: This was a multi centre, non-randomised trial recruiting obese patients with type 2 diabetes from three sites in the UK. Eligible participants had a BMI of 30-50 kg/m2 and HbA1c levels of 7.5-10%. The study comprised a 12-month period with the EndoBarrier(r) inserted and a 6-month follow-up period after it had been explanted. The primary study outcomes were weight, BMI, HbA1c levels and fasting insulin and glucose levels. RESULTS: Forty-five patients were recruited and 31 patients (69%) completed the 12-month study period. Significant reductions in weight (95%CI 0.62 29.38; p < 0.05) and BMI (95%CI 1.1-8.7; p < 0.005) were documented 12 months after device insertion. The mean HbA1c was significantly reduced (95%CI 0.1-1.6; p < 0.05) after the device insertion period and reductions in metabolic parameters (fasting insulin and glucose levels) were also documented during the study. Adverse events were also assessed in all patients, the vast majority of which were reported as mild. CONCLUSIONS: The EndoBarrier(r) appears to be a safe and effective treatment strategy in overweight patients with poor glycaemic control despite medical therapy, or in those who are eligible but decline bariatric surgery.

PMID- 29450845 TI - Endoscopic Sleeve Gastroplasty (ESG) Is a Reproducible and Effective Endoscopic Bariatric Therapy Suitable for Widespread Clinical Adoption: a Large, International Multicenter Study. AB - OBJECTIVE: Endoscopic sleeve gastroplasty (ESG), an incisionless endoscopic bariatric procedure, has shown impressive results in case series. This study examines the reproducibility, efficacy, and safety in three centers across two countries, and identifies key determinants for procedural success. DESIGN: Patients who underwent ESG between February 2016 and May 2017 at one of three centers (Australia and USA) were retrospectively analyzed. All procedures were performed on an outpatient basis using the Apollo OverStitch device (Apollo Endosurgery, Austin, TX). Primary outcomes included absolute weight loss (DeltaWeight, kg), change in body mass index (?BMI, in kg/m2), total body weight loss (TBWL, %), excess weight loss (EWL, in %), and immediate and delayed adverse events. RESULTS: In total, 112 consecutive patients (male 31%, age 45.1 +/- 11.7 years, baseline BMI 37.9 +/- 6.7 kg/m2) underwent ESG. At 1, 3, and 6 months, Deltaweight was 9.0 +/- 4.6 kg (TBWL 8.4 +/- 4.1%), 12.9 +/- 6.4 kg (TBWL 11.9 +/ 4.5%), and 16.4 +/- 10.7 kg (TBWL 14.9 +/- 6.1%), respectively. The proportion of patients who attained greater than 10% TBWL and 25% EWL was 62.2 and 78.0% at 3 months post-ESG and 81.0 and 86.5% at 6 months post-ESG. Weight loss was similar between the three centers. Multivariable analysis showed that male sex, greater baseline body weight, and lack of prior endoscopic bariatric therapy were predictors of greater Deltaweight at 6 months. Three (2.7%) severe adverse events were observed. CONCLUSIONS: ESG is an effective, reproducible, and safe weight loss therapy that is suitable for widespread clinical adoption.

AB - Laugier-Hunziker syndrome (LHS, also termed idiopathic lenticular mucocutaneous hyperpigmentation) is an unusual condition characterized by progressive pigmentation of the mucous membranes. LHS displays a benign course and is not associated with malignancy. Here we present a case of LHS with a 7-year follow up. We document metachronous oral melanoacanthomas in this individual. In addition, we found that the oral melanotic macules in this patient waxed and waned in a cyclical manner. To our knowledge, this is the first report of these findings in the context of LHS. Finally, we provide an overview of other conditions that can present with mucosal hyperpigmentation. It is critical to distinguish LHS from other conditions characterized by mucosal pigmentation in order to facilitate optimal patient care. PMID- 29450848 TI - Automated Pathogenesis-Based Diagnosis of Lumbar Neural Foraminal Stenosis via Deep Multiscale Multitask Learning. AB - Pathogenesis-based diagnosis is a key step to prevent and control lumbar neural foraminal stenosis (LNFS). It conducts both early diagnosis and comprehensive assessment by drawing crucial pathological links between pathogenic factors and LNFS. Automated pathogenesis-based diagnosis would simultaneously localize and grade multiple spinal organs (neural foramina, vertebrae, intervertebral discs) to diagnose LNFS and discover pathogenic factors. The automated way facilitates planning optimal therapeutic schedules and relieving clinicians from laborious workloads. However, no successful work has been achieved yet due to its extreme challenges since 1) multiple targets: each lumbar spine has at least 17 target organs, 2) multiple scales: each type of target organ has structural complexity and various scales across subjects, and 3) multiple tasks, i.e., simultaneous localization and diagnosis of all lumbar organs, are extremely difficult than individual tasks. To address these huge challenges, we propose a deep multiscale multitask learning network (DMML-Net) integrating a multiscale multi-output learning and a multitask regression learning into a fully convolutional network. 1) DMML-Net merges semantic representations to reinforce the salience of numerous target organs. 2) DMML-Net extends multiscale convolutional layers as multiple output layers to boost the scale-invariance for various organs. 3) DMML-Net joins a multitask regression module and a multitask loss module to prompt the mutual benefit between tasks. Extensive experimental results demonstrate that DMML-Net achieves high performance (0.845 mean average precision) on T1/T2-weighted MRI scans from 200 subjects. This endows our method an efficient tool for clinical LNFS diagnosis. PMID- 29450851 TI - ECR 2018 - BOOK OF ABSTRACTS.

Serum urate (sUA) and high-sensitivity C reactive protein (hsCRP) were measured in the gout group, and correlated with FMD and NMD responses. Both FMD (2.20 +/- 0.53 vs 3.56 +/- 0.31, p = 0.021) and NMD (16.69 +/- 1.54 vs 24.51 +/- 0.90, p = 0.00002) were impaired in the gout versus control group. Stratification for individual comorbidities suggested that no single risk factor accounted for impaired FMD/NMD in the gout subjects. However, the degree of association between gout and FMD, but not NMD impairment, was dampened after multivariable adjustment (FMD unadjusted beta = - 1.36 (SE 0.58), p = 0.02; adjusted beta = - 1.16 (SE 0.78), p = 0.14 and NMD unadjusted beta = - 7.68 (SE 1.78), p < 0.0001; adjusted beta = - 5.33 (SE 2.46), p = 0.03). Within the gout group, there was an inverse correlation between FMD and sUA (R = - 0.5, p = 0.003), and between FMD and hsCRP (R = - 0.42, p = 0.017), but not between NMD and sUA or hsCRP. Compared with healthy controls, subjects with gout have reduced arterial function. Individual comorbidities are insufficient to account for differences between gout and control groups, but multiple comorbidities may collectively contribute to impairment in endothelium-dependent arterial responsiveness. Endothelial impairment is also related to sUA and hsCRP, markers of gout severity and inflammation respectively. Studies to determine whether gout therapy may improve arterial responsiveness are warranted. PMID- 29450850 TI - Recurrent fever and arthralgia as the presentation of tumor necrosis factor receptor-associated periodic syndrome (TRAPS) in a Chinese girl: a case report and review of the literature. AB - Tumor necrosis factor receptor-associated periodic syndrome (TRAPS) is characterized by recurrent episodes of inflammation with fever, abdominal pain, chest pain, rash, myalgia, arthralgia, conjunctivitis, and periorbital edema. This condition is a rare autosomal dominant disease that is strongly associated with heterozygous mutations in the tumor necrosis factor (TNF) receptor super family 1A (TNFRSF1A) gene. This condition is believed to be more common in Western countries than in Asian countries, and the AA amyloidosis rate for European countries is estimated to be 10%. Herein, we report the case of a 14 year-old girl with recurrent fever and arthralgia with inflammatory marker elevation for 10 years. After extensive investigation of the infectious etiology with negative results and similar phenomenon observed within her family, the diagnosis of TRAPS was made based on next-generation sequencing, which revealed a T50M mutation; she was also sensitive to corticosteroids. Although none of our TRAPS patients developed AA amyloidosis, we suggest the continual monitoring of urinalysis results and serum amyloid A concentrations during long-term follow-up. Moreover, we also reviewed the related literature and found no Asian patients who had developed AA amyloidosis. PMID- 29450852 TI - Major pancreatic resections: normal postoperative findings and complications. AB - OBJECTIVES: (1) To illustrate and describe the main types of pancreatic surgery; (2) to discuss the normal findings after pancreatic surgery; (3) to review the main complications and their radiological findings. BACKGROUND: Despite the decreased postoperative mortality, morbidity still remains high resulting in longer hospitalisations and greater costs. Imaging findings following major pancreatic resections can be broadly divided into "normal postoperative alterations" and real complications. The former should regress within a few months whereas complications may be life-threatening and should be promptly identified and treated. IMAGING FINDINGS: CT is the most effective postoperative imaging technique. MRI and fluoroscopy are used less often and only in specific cases such as assessing the gastro-intestinal function or the biliary tree. The most common normal postoperative findings are pneumobilia, perivascular cuffing, fluid collections, lymphadenopathy, acute anastomotic oedema and stranding of the peri-pancreatic/mesenteric fat. Imaging depicts the anastomoses and the new postoperative anatomy. It can also demonstrate early and late complications: pancreatic fistula, haemorrhage, delayed gastric emptying, hepatic infarction, acute pancreatitis of the remnant, porto-mesenteric thrombosis, abscess, biliary anastomotic leaks, anastomotic stenosis and local recurrence. CONCLUSIONS: Radiologists should be aware of surgical procedures, postoperative anatomy and normal postoperative imaging findings to better detect complications and recurrent disease. TEACHING POINTS: * Morbidity after pancreatic resections is high. * CT is the most effective postoperative imaging technique. * Imaging depicts the anastomoses and the new postoperative anatomy. * Pancreatic fistula is the most common complication after partial pancreatic resection. PMID- 29450853 TI - Endometriosis: clinical features, MR imaging findings and pathologic correlation. AB - OBJECTIVE: We illustrate the magnetic resonance imaging (MRI) features of endometriosis. BACKGROUND: Endometriosis is a chronic gynaecological condition affecting women of reproductive age and may cause pelvic pain and infertility. It is characterized by the growth of functional ectopic endometrial glands and stroma outside the uterus and includes three different manifestations: ovarian endometriomas, peritoneal implants, deep pelvic endometriosis. The primary locations are in the pelvis; extrapelvic endometriosis may rarely occur. Diagnosis requires a combination of clinical history, invasive and non-invasive techniques. The definitive diagnosis is based on laparoscopy with histological confirmation. Diagnostic imaging is necessary for treatment planning. MRI is as a second-line technique after ultrasound. The MRI appearance of endometriotic lesions is variable and depends on the quantity and age of haemorrhage, the amount of endometrial cells, stroma, smooth muscle proliferation and fibrosis. The purpose of surgery is to achieve complete resection of all endometriotic lesions in the same operation. CONCLUSION: Owing to the possibility to perform a complete assessment of all pelvic compartments at one time, MRI represents the best imaging technique for preoperative staging of endometriosis, in order to choose the more appropriate surgical approach and to plan a multidisciplinary team work. TEACHING POINTS: * Endometriosis includes ovarian endometriomas, peritoneal implants and deep pelvic endometriosis. * MRI is a second-line imaging technique after US. * Deep pelvic endometriosis is associated with chronic pelvic pain and infertility. * Endometriosis is characterized by considerable diagnostic delay. * MRI is the best imaging technique for preoperative staging of endometriosis. PMID- 29450855 TI - Health-related quality of life among US military personnel injured in combat: findings from the Wounded Warrior Recovery Project. AB - PURPOSE: Little is known about the long-term, health-related quality of life (HRQOL) of those wounded in combat during Operations Enduring Freedom, Iraqi Freedom, and New Dawn. The present study described the overall HRQOL for a large group of US service members experiencing mild-to-severe combat-related injuries, and assessed the unique contribution of demographics, service- and injury-related characteristics, and mental health factors on long-term HRQOL. METHOD: The Wounded Warrior Recovery Project examines patient-reported outcomes in a cohort of US military personnel wounded in combat. Participants were identified from the Expeditionary Medical Encounter Database, a US Navy-maintained deployment health database, and invited to complete a web-based survey. At the time of this study, 3245 service members consented and completed the survey. Hierarchical linear regression analyses were conducted to assess the unique contribution of each set of antecedents on HRQOL scores. RESULTS: HRQOL was uniquely associated with a number of demographics, and service- and injury-related characteristics. Nevertheless, screening positive for posttraumatic stress disorder (B = - .09; P < .001), depression (B = - .10; P < .001), or both as a set (B = - .19; P < .001) were the strongest predictors of lower long-term HRQOL. CONCLUSIONS: Postinjury HRQOL among service members wounded in combat was associated with service and injury experience, and demographic factors, but was most strongly linked with current mental health status. These findings underscore the significance of mental health issues long after injury. Further, findings reinforce that long term mental health screening, services, and treatment are needed for those injured in combat. PMID- 29450854 TI - Imaging of the scrotum: beyond sonography. AB - : The aim of this article is to describe the role of second-level imaging techniques after an initial ultrasonography evaluation in the assessment of scrotal diseases. While ultrasonography remains central as the primary imaging modality for the evaluation of pathologic conditions of the scrotum, the role of magnetic resonance imaging continues to evolve: it can actually be valuable as a problem-solving tool when sonographic findings are equivocal or inconclusive. Magnetic resonance imaging of the scrotum may provide accurate detection and characterization of scrotal diseases, well depicting the precise location of scrotal masses (intratesticular or extratesticular) and reliably characterizing benign conditions simulating neoplastic processes, thus preventing unnecessary radical surgery. Advanced magnetic resonance techniques, most of all diffusion weighted imaging and magnetic resonance spectroscopy, play in the meanwhile a more significant role in evaluating scrotal diseases. TEACHING POINTS: * Multiparametric ultrasonography usually represents the initial imaging modality for approaching scrotal diseases. * MRI is well established as a problem-solving tool for inconclusive sonographic findings. * Advanced MRI techniques can be successfully applied in scrotal pathology assessment. * MRI is valuable in differentiating benign conditions from neoplastic processes. * CT plays a role in trauma assessment and cancer staging alongside PET/CT. PMID- 29450856 TI - Hysterectomy and perceived physical function in middle-aged Australian women: a 20-year population-based prospective cohort study. AB - PURPOSE: Hysterectomy is one of the most common gynaecological procedures worldwide. Changes in endocrine function may impact age-associated decline in physical function and these changes may be accelerated by hysterectomy. The aim of this study was to investigate associations between hysterectomy status and self-reported physical function limitations. METHODS: Our study sample (n = 8624) came from the mid-cohort (born 1945-1950) of the Australian Longitudinal Study on Women's Health (ALSWH). Self-report of physical function was measured by the Physical Functioning (PF) subscale of the Medical Outcomes Study Short Form Health Survey (SF-36) over seven surveys (1998-2016), categorised into substantial, moderate and minimal PF-limitations. The associations between hysterectomy status and de novo substantial or moderate PF-limitations versus minimal PF-limitations were investigated using log-multinomial regression. RESULTS: By Survey 8 (2016), 20% of the study sample had a hysterectomy with ovarian conservation (hysterectomy only) and 9% had a hysterectomy and both ovaries removed (hysterectomy-bilateral oophorectomy). Women with a hysterectomy only had a small increase in risk of substantial PF-limitations (versus minimal PF-limitations) compared to women with no hysterectomy (relative risk [RR]: 1.13; 95% confidence interval [95% CI] 1.00-1.27); the point estimate was stronger for women with a hysterectomy-bilateral oophorectomy (RR: 1.26; 95% CI 1.09-1.46). In a supplementary analysis, the increased risk of substantial PF-limitations was seen only in women who had surgery before the age of 45 years. CONCLUSIONS: Compared to women with no hysterectomy, women with hysterectomy-bilateral oophorectomy were at increased risk of substantial PF-limitations versus minimal PF-limitations over 18 years of follow-up. PMID- 29450857 TI - Hypokalemia associated with pseudo-Cushing's syndrome and magnesium deficiency induced by chronic alcohol abuse. AB - Hypokalemia and hypomagnesemia are frequently observed in patients with chronic alcoholism. However, the involvement of deranged cortisol regulation in patients with those conditions has not been reported. A 63-year-old Japanese male with chronic alcoholism was referred to the Department of Diabetes, Endocrinology and Metabolism for examination and treatment of hypokalemic periodic paralysis. Laboratory findings showed hypokalemia (2.3 mmol/l), as well as a high level of urinary excretion of potassium and hypomagnesemia (1.2 mg/dl), whereas urinary excretion of magnesium was undetectable. Potassium infusion treatment recovered that level in serum to 4.1 mmol/l, though it decreased to 2.2 mmol/l following discontinuation. A dexamethasone suppression test and urinary cortisol level showed corticotropin-dependent hypercortisolemia. However, gadolinium-enhanced MRI revealed no evidence of pituitary adenoma. The patient recovered from hypokalemia following an administration of magnesium in addition to potassium, which was accompanied by potassium over-excretion improvement. After being discharged, serum potassium level was maintained within a normal range with only magnesium infusion treatment. Furthermore, alcohol intake was reduced from 160 to 20 g/day and an endocrinological re-examination after that restriction showed normal cortisol regulation. The patient was diagnosed with pseudo-Cushing's syndrome induced by alcohol abuse. Serum potassium level was maintained within a normal range even after discontinuation of magnesium supplementation. Our findings in this case indicate that pseudo-Cushing's syndrome in conjunction with hypomagnesemia may be involved in development of hypokalemia in patients with chronic alcoholism. PMID- 29450858 TI - In-Source Reduction of Disulfide-Bonded Peptides Monitored by Ion Mobility Mass Spectrometry. AB - Many peptides with antimicrobial activity and/or therapeutic potential contain disulfide bonds as a means to enhance stability, and their quantitation is often performed using electrospray ionization mass spectrometry (ESI-MS). Disulfides can be reduced during ESI under commonly used instrument conditions, which has the potential to hinder accurate peptide quantitation. We demonstrate that this in-source reduction (ISR) is predominantly observed for peptides infused from acidic solutions and subjected to elevated ESI voltages (3-4 kV). ISR is readily apparent in the mass spectrum of oxytocin-a small, single disulfide-containing peptide. However, subtle m/z shifts due to partial ISR of highly charged (z >= 3) peptides with multiple disulfide linkages may proceed unnoticed. Ion mobility (IM)-MS separates ions on the basis of charge and shape in the gas phase, and using insulin as a model system, we show that IM-MS arrival time distributions (ATDs) are particularly sensitive to partial ISR of large peptides. Isotope modeling allows for the relative quantitation of disulfide-intact and partially reduced states of the mobility-separated peptide conformers. Interestingly, hepcidin peptides ionized from acidic solutions at elevated ESI voltages undergo gas-phase compaction, ostensibly due to partial disulfide ISR. Our IM-MS results lead us to propose that residual acid is the likely cause of disparate ATDs recently measured for hepcidin from different suppliers [Anal. Bioanal. Chem. 409, 2559-2567 (2017)]. Overall, our results demonstrate the utility of IM-MS to detect partial ISR of disulfide-bonded peptides and reinforce the notion that peptide/protein measurements should be carried out using minimally activating instrument conditions. Graphical Abstract ?. PMID- 29450859 TI - Congenital Adrenal Hyperplasia (CAH) due to 21-Hydroxylase Deficiency: A Comprehensive Focus on 233 Pathogenic Variants of CYP21A2 Gene. AB - Congenital adrenal hyperplasia (CAH) comprises a group of autosomal recessive disorders caused by complete or partial defects in one of the several steroidogenic enzymes involved in the synthesis of cortisol from cholesterol in the adrenal glands. More than 95-99% of all cases of CAH are caused by deficiency of steroid 21-hydroxylase, an enzyme encoded by the CYP21A2 gene. Currently, CYP21A2 genotyping is considered a valuable complement to biochemical investigations in the diagnosis of 21-hydroxylase deficiency. More than 200 mutations have been described in literature reports, and much energy is still focused on the clinical classification of new variants. In this review, we focus on molecular genetic features of 21-hydroxylase deficiency, performing an extensive survey of all clinical pathogenic variants modifying the whole sequence of the CYP21A2 gene. Our aim is to offer a very useful tool for clinical and genetic specialists in order to ease clinical diagnosis and genetic counseling. PMID- 29450861 TI - Revision of "Aemilia" pagana Species-Group (Lepidoptera: Erebidae: Arctiinae), with a Description of a New Endemic Species and Comments on the Conservation Status. AB - A taxonomical rearrangement of "Aemilia" pagana species-group is proposed: Leucanopsis pagana (Schaus in Proc Zool Soc London 1894:225-243, 1894) comb. nov. and L. ninae (Orfila in Rev Soc Entomol Argent 21:67-70, 1959) comb. nov. A new endemic species from Pampa de Achala, Cordoba, Argentina, closer to both species, is described: Leucanopsis navarroi sp. nov. These three species can be recognized because the color pattern is the darkest among species of Leucanopsis. Characteristics of male genitalia suggest the nomenclatural rearrangement proposed. Leucanopsis pagana comb. nov. has a wide distribution from the center of Brazil to northeastern Argentina, including southern Paraguay. The known distribution and geospatial analysis suggest that this species is not in danger. Leucanopsis ninae comb. nov. is restricted to only one known locality (Villa Gesell, Buenos Aires). The restricted known distribution, the different land use practices, and geospatial analysis suggest that this species could be endangered. Leucanopsis navarroi sp. nov. is endemic to the high plateau present in the center of Argentina called Pampa de Achala. The known distribution and geospatial analysis suggest that this species could be endangered. Further studies are necessary to determine effectively the conservation status of these three species. PMID- 29450860 TI - Morphological Characterization of Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae: Heliothinae). AB - The cotton bollworm Helicoverpa armigera (Hubner) is a widespread lepidopteran pest found in various crops worldwide. This highly polyphagous species, commonly found both in the Old and New World, has caused significant economic damage as an invasive agricultural pest in Brazil since 2013. The goal of the present study is to provide a detailed morphological assessment of adults and immature stages of H. armigera, as this species is often confused with H. zea (Boddie), a congeneric species that is native to the New World. The biology data were acquired during four full life cycles, and observations on general behavior, nocturnal habits of larvae and adults, and sensitivity of larvae to humidity were recorded. Larval chaetotaxy differs between the first and the remaining instars, which bear L2 on the meso- and metathorax and L3 on A3 through A6, along with conspicuous chalazae and longitudinal bands. Important morphological characters of this species include the following: eggs with four micropylar openings, lined with 12 cells arranged in the shape of a rosette; pupa adecticous and obtect, with prominent spiracles; adults with the distal antennomere striate. Adults exhibit sexual dimorphism in the number of setae on the frenulum and spines on the prothoracic leg. Illustrations of the critical morphological features of this species are provided. PMID- 29450862 TI - Recent progress in dendrimer-based nanomedicine development. AB - Dendrimers offer well-defined nanoarchitectures with spherical shape, high degree of molecular uniformity, and multiple surface functionalities. Such unique structural properties of dendrimers have created many applications for drug and gene delivery, nanomedicine, diagnostics, and biomedical engineering. Dendrimers are not only capable of delivering drugs or diagnostic agents to desired sites by encapsulating or conjugating them to the periphery, but also have therapeutic efficacy in their own. When compared to traditional polymers for drug delivery, dendrimers have distinct advantages, such as high drug-loading capacity at the surface terminal for conjugation or interior space for encapsulation, size control with well-defined numbers of peripheries, and multivalency for conjugation to drugs, targeting moieties, molecular sensors, and biopolymers. This review focuses on recent applications of dendrimers for the development of dendrimer-based nanomedicines for cancer, inflammation, and viral infection. Although dendrimer-based nanomedicines still face some challenges including scale up production and well-characterization, several dendrimer-based drug candidates are expected to enter clinical development phase in the near future. PMID- 29450863 TI - Using Self-Reported Patient Experiences to Understand Patient Burden: Learnings from Digital Patient Communities in Ankylosing Spondylitis. AB - INTRODUCTION: Online communities contain a wealth of information containing unsolicited patient experiences that may go beyond what is captured by guided surveys or patient-reported outcome (PRO) instruments used in clinical settings. This study described patient experiences reported online to better understand the day-to-day disease burden of ankylosing spondylitis (AS). METHODS: Unguided, English-language patient narratives reported between January 2010 and May 2016 were collected from 52 online sources (e.g., general/health social networking sites, patient-physician Q&A sites, AS forums). Using natural language processing combined with manual curation, patient-reported experiences within narratives were evaluated and categorized into social, physical, emotional, cognitive, and role activity (SPEC-R) concepts to assess functional impairment. The same SPEC-R categorization was applied to 5 AS-specific PRO instruments to evaluate their coverage of concepts extracted from patient narratives. RESULTS: A total of 34,780 narratives from 3449 patients with AS were included. Physical aspects of AS (e.g., pain and mobility) were most commonly reported by patients (86.7%), followed by emotional (32.5%), cognitive (23.6%), role activity (8.7%) and social (5.1%). Some frequently discussed subconcepts were effectively captured by >= 2 PRO instruments, such as pain (65.3%), asthenia (19.9%), musculoskeletal impairment (19.9%), depression (9.9%), and anger/frustration (5.4%); others [e.g., anxiety (19.1%), mental impairment (3.2%), impulsivity (2.9%)] were not addressed by any of the PRO instruments. CONCLUSION: These findings highlight the importance of analyzing patient experiences beyond clinical trial settings and physician reports; continuous assessment of existing PRO instruments in collaboration with patients may increase their utility in real-world settings.

AB - INTRODUCTION: The prevalence of endometriosis and the need for treatment in the USA has led to the need to explore the contemporary cost burden associated with the disease. This retrospective cohort study compared direct and indirect healthcare costs in patients with endometriosis to a control group without endometriosis. METHODS: Women aged 18-49 years with endometriosis (date of initial diagnosis = index date) were identified in the Truven Health MarketScan(r) Commercial database between 2010 and 2014 and female control patients without endometriosis were matched by age and index year. The following outcomes were compared: healthcare resource utilization (HRU) during the 12-month pre- and post-index periods (including inpatient admissions, pharmacy claims, emergency room visits, physician office visits, and obstetrics/gynecology visits), annual direct (medical and pharmacy) and indirect (absenteeism, short term disability, and long-term disability) healthcare costs during the 12-month post-index period (in 2014 US$). Multivariate analyses were conducted to estimate annual total direct and indirect costs, controlling for demographics, pre-index clinical characteristics, and pre-index healthcare costs. RESULTS: Overall, 113,506 endometriosis patients and 927,599 controls were included. Endometriosis patients had significantly higher HRU during both the pre- and post-index periods compared to controls (p < 0.0001, all categories of HRU). Approximately two thirds of endometriosis patients underwent an endometriosis-related surgical procedure (including laparotomy, laparoscopy, hysterectomy, oophorectomy, and other excision/ablation procedures) in the first 12 months post-index. Mean annual total adjusted direct costs per endometriosis patient during the 12-month post-index period was over three times higher than that for a non-endometriosis control [$16,573 (standard deviation (SD) = $21,336) vs. $4733 (SD = $14,833); p < 0.005]. On average, incremental direct and indirect 12-month costs per endometriosis patient were $10,002 and $2132 compared to their matched controls (p < 0.005). CONCLUSIONS: Endometriosis patients incurred significantly higher direct and indirect healthcare costs than non-endometriosis patients. FUNDING: AbbVie Inc.

PMID- 29450866 TI - Rehabilitative orbital decompression for Graves' orbitopathy: results of a randomized clinical trial. AB - PURPOSE: Orbital decompression (OD) is a consolidated procedure for the treatment of exophthalmos in Graves' orbitopathy (GO). The efficacy of the various procedures remains unclear due to the variability of the techniques used. To address this issue, we performed a randomized clinical trial to compare the efficacy of two surgical techniques. The primary endpoint was the reduction in proptosis. Secondary aims were the risk of post-operative diplopia (POD) in primary gaze and other surgical complications. PATIENTS: 38 patients (76 orbits) affected with GO were enrolled and randomized into single lateral decompression (LD) (n = 19) or balanced medial plus lateral wall decompression (MLD) (n = 19). Following surgery, patients were seen for a follow-up ophthalmological evaluation at 6 months. Pre-operative diplopia in secondary gaze was present in 13/38 patients (34.2%, 8/19 treated with LD and 5/19 treated with MLD). RESULTS: The reduction of exophthalmos was greater in patients treated with MLD (5.1 +/- 1.5 mm, range 2-8 mm) than in those treated with LD (3.5 +/- 1.3 mm, range 1-6.5 mm) (p = 0.01). The overall incidence of POD in primary gaze was 5/38 (13.2%) and all of these patients had pre-operative diplopia in secondary gaze (5/13, 38.5%, vs patients with no pre-operative diplopia p = 0.005). Two of 19 patients (10.5%) treated with LD and 3/19 (15.8%) treated with MLD, developed POD in primary gaze, with no statistical difference between the two techniques. CONCLUSION: MLD provides a better result in terms of proptosis reduction compared to LD. The two techniques used here appear to have a similar safety profile in terms of POD. Pre operative diplopia in the secondary gaze remains a major risk factor for development of POD. PMID- 29450867 TI - 20S proteasome in the blood plasma of boys with cryptorchidism. AB - PURPOSE: To evaluate the concentration of 20S proteasome in the blood plasma of boys with cryptorchidism. METHODS: Patients-50 boys aged 1-4 years (median = 2.4 years) with unilateral cryptorchidism. The control group-50 healthy, age-matched boys (aged 1-4 years, median = 2.1 years), admitted for planned herniotomy. In our study, we used a novel technique Surface PLASMON RESONANCE Imaging. RESULTS: The median concentration of 20S proteasome in the blood plasma of boys with cryptorchidism was 2.5-fold higher than in boys with inguinal hernia. We noticed statistically significant difference between 20S proteasome levels in boys with cryptorchidism up to 2 years old and above 2 years old. CONCLUSIONS: We believe that the 20S proteasome concentrations in the blood plasma of boys with cryptorchidism reflect the heat-induced apoptosis of germ cells. PMID- 29450868 TI - Hepatocholangiocarcinoma/intrahepatic cholangiocarcinoma: are they contraindication or indication for liver transplantation? A propensity score matched analysis. AB - BACKGROUND: Uncommon primary hepatic malignancies such as intrahepatic cholangiocarcinoma (ICC) and hepatocholangiocarcinoma (HCC-CC) were generally considered contraindications for liver transplantation(LT), and studies comparing the efficacy of LT and resection (LR) for ICC/HCC-CC were scarce. OBJECTIVE: To compare the survival outcomes of ICC/HCC-CC patients treated by LT and LR in a propensity score-matched population. METHOD: This is a retrospective study from 1995 to 2015. Consecutive patients with the pathological diagnosis of ICC or HCC CC in the surgical specimens were included. All patients had either hepatectomy or LT with curative intent. Factors associated with survival were identified with multivariate analysis using cox-regression model. Propensity score-matched analysis was performed. RESULT: There were 181 patients diagnosed to have ICC/HCC_CC. Nine patients received LT (all with incidental ICC/HCC-CC) and 172 received hepatectomy. The median follow-up period was 27.5 months. The median age was 60 years (range 3-86); Hepatitis B and C carrier status was found in 48.1 and 2.3% of the patients, respectively. The median tumor size was 6 cm and 71.3% of them had solitary tumor. Microvascular invasion was present in 47% of the patients. After propensity score matching, there were 54 (9 in LT and 45 in LR group) patients for analysis. Cox-regression analysis showed that early AJCC (7th) staging and LT were the independent factors associated with overall survival. Patients in the LT group had significantly better overall survival (5 year OS 77.8 vs 36.6%, log-rank p = 0.013). CONCLUSION: ICC/HCC-CC are uncommon tumors with poor long-term oncological outcomes despite curative hepatectomy. Liver transplantation might be a better treatment option for patients with early ICC/HCC-CC. PMID- 29450870 TI - Early and long period follow-up results of low glycemic index diet for migraine prophylaxis. AB - OBJECTIVES: The role of dietary restriction in the management of patients with migraine is still a controversial topic in the headache field. The aim of this study was to evaluate the efficacy of dietary restriction on migraine attacks. METHODS: Patients diagnosed with migraine without aura according to the International Classification of Headaches were enrolled. Our study included 350 migraine patients evaluated at the neurology headache outpatient clinic. They were randomly divided into two groups: diet group as the study group and medication group as the control group. We told migraine patients to make lifestyle changes, especially those with low glycemic index in the diet group. On the other hand, propranolol, amitriptyline, flunarizine, and topiramate were used for the prophylaxis in the medication group. The frequency and severity of attacks [using the visual analog scale (VAS)] were recorded before starting dietary restriction and 1 and 3 months after the dietary restriction. RESULTS: There were 350 participants in this study. After 3 months, a total of 147 patients (male/female: 17/130, mean age: 34.7+/-5.9) were evaluated in the diet group. The control group consisted of 147 age- and sex-matched, randomly selected patients with migraine without aura. In the first month after dietary restriction, monthly attack frequency significantly decreased in both groups but not the VAS score. The mean scores of VAS significantly decreased later in the diet group compared with those in the medication group (after 3 months). CONCLUSION: The results of the study revealed that low glycemic index diet intake can be an effective and reliable method to reduce migraine attacks. PMID- 29450869 TI - Long-term observation of acute-onset autoimmune hepatitis presenting clinically and radiologically as acute hepatitis. AB - BACKGROUND: There is yet no gold standard for the diagnosis of acute-onset autoimmune hepatitis (A-AIH), especially histologically acute AIH. As a result, long-term observation of A-AIH has been difficult and the nature is not well known. We retrospectively analyzed the clinicopathological features of A-AIH over a long prospective follow-up period. METHODS: Clinical, biochemical, immunological and pathological features of 30 patients (21 female, mean age 55.1 +/- 13.1 years) with non-severe A-AIH "without signs of clinical and radiological chronicity" admitted to a community hospital between 2001 and 2015 who were prospectively followed for more than 2 years were analyzed retrospectively. RESULTS: Liver histology of 45% showed acute and 55% chronic hepatitis. Mean age was older, prothrombin time activity was higher, AIH scores before treatment were lower in histologically acute hepatitis than histologically chronic hepatitis significantly. Liver fibrosis was not coarse, but delicate with severe activity in most patients showing chronic hepatitis defined by our strict criteria. Median (range) follow-up period was 6.9 (2.1-16.2) years. Six (20%) patients experienced episode of relapses. All were alive at the last follow-up point. Corticosteroid was continued at 2.5-5 mg/day until the study end point without serious side effects in most patients. Serial change of alanine aminotransferase levels, immunoglobulin G levels and anti-nuclear antibody titers did not show statistical difference between histologically acute and chronic hepatitis. CONCLUSION: Rapid progression of fibrosis could occur in A-AIH. Treatment response and long-term prognosis were good, and not different between patients with histologically acute and chronic hepatitis. PMID- 29450871 TI - Characteristics of headache and its relationship with disease severity in patients with Crimean-Congo hemorrhagic fever. AB - OBJECTIVES: Crimean-Congo Hemorrhagic Fever (CCHF) is a fatal, tick-borne disease. The classic clinical presentation of CCHF is characterized by sudden onset of high fever, chills, and severe headache. There are no previous reports on the characteristics of headaches caused by CCHF. Therefore, we investigated the relationship between CCHF-induced headache and the clinical course of the disease. METHODS: We included 60 patients with headache diagnosed with CCHF; they were divided into two groups: group 1 included patients with hospital stay <7 days and group 2 included patients with hospital stay >7 days. The control group included 43 viral pneumonia patients with headache. Patients described the characteristics of headaches and also self-rated the severity with a numeric pain scale that classified headache as either mild or severe. RESULTS: In the group with CCHF, 66.7% of the reported headaches met criteria for diagnosis of migraine. This ratio was significantly higher than that in the control group (37.5%). The headache severity scores in group 1 were lower than those in group 2. The hospitalization length was shorter (p=0.004) and the platelet levels were higher in CCHF patients with mild headache compared with CCHF patients with severe headache (p=0.005). CONCLUSION: CCHF patients had more often and severe headaches than the controls. The severity of headache may be associated with the severity of vascular endothelial damage, vasodilatation, and abnormal release of inflammatory cytokines in CCHF similar in migraine. Most CCHF patients experienced migraine-like headaches, suggesting that cerebral vessel involvement might be important in both CCHF and migraine.

AB - OBJECTIVES: This study aimed to develop a Turkish version of the Fear of Pain Questionnaire-III developed by McNeil and Rainwater (1998) and examine its validity and reliability indicators. METHODS: The study was conducted with 459 university students studying in the nursing department. The Turkish translation of the scale was conducted by language experts and the original scale owner. Expert opinions were taken for language validity, and the Lawshe's content validity ratio formula was used to calculate the content validity. Exploratory factor analysis was used to assess the construct validity. The factors were rotated using the Varimax rotation (orthogonal) method. For reliability indicators of the questionnaire, the internal consistency coefficient and test re test reliability were utilized. RESULTS: Explanatory factor analyses using the three-factor model (explaining 50.5% of the total variance) revealed that the item factor loads varied were above the limit value of 0.30 which indicated that the questionnaire had good construct validity. The Cronbach's alpha value for the total questionnaire was 0.938, and test re-test value was 0.846 for the total scale. CONCLUSION: The Turkish version of the Fear of Pain Questionnaire-III had sufficiently high reliability and validity to be used as a tool in evaluating the fear of pain among the young Turkish population.

AB - Short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) is a rare, primary headache syndrome, which is classified as a subtype of trigeminal autonomic cephalalgias. Although SUNCT is usually refractory to treatment, several antiepileptic drugs have recently shown promising results for its treatment. However, there is a lack of evidence regarding the course of SUNCT during pregnancy and the available treatment options. Here, we present a 30-week pregnant female with SUNCT who was successfully treated with infra- and supraorbital nerve blocks. Headache attacks completely diminished after the injection, and recurrence was not observed. Although lamotrigine may be relatively safe in pregnant patients with SUNCT attacks, peripheral nerve block may be a feasible technique and can be considered as a safe and effective treatment option. This is the first SUNCT case in the literature that was successfully treated with infra- and supraorbital nerve blocks during pregnancy. PMID- 29450874 TI - What happened? An inexplicable case: Accidental subdural block. AB - Epidural block is an appropriate anesthesia method for outpatient operation. This technique is generally safe and efficient. We present the case of a 20-year-old female patient with accidental subdural block after a single dose of epidural block for pilonidal sinus surgery. Sudden apnea, unconsciousness, and bilateral mydriasis occurred within a few minutes after injection. Within 80 minutes after injection, the patient regained full consciousness and spontaneous respiration, with motor block in lower extremities and sensory block until the T4 level. Motor block continued until 165 minutes after injection, whereas sensory block ended 225 minutes later. PMID- 29450875 TI - [Coexistence of polymyalgia rheumatica with ankylosing spondylitis: A case report]. AB - Ankylosing spondylitis is a chronic inflammatory disease that affects the spine and peripheral joints. Polymyalgia rheumatica is an inflammatory disease characterized by aching and prolonged morning stiffness mainly in the shoulder and pelvic girdles. Many other diseases may mimic polymyalgia rheumatica, and thus differential diagnosis is predominantly required. A wide variety of diseases, including spondyloarthropathies, may present polymyalgia-like symptoms, and two diseases rarely coexist. We present a case of a 54-year-old man who had been followed-up for ankylosing spondylitis and presented with pain in the shoulder and pelvic girdles, restricted movement, and morning stiffness for 2 months. Physical examination revealed that the pain was located mostly in the shoulder and pelvic girdles. In addition, increased erythrocyte sedimentation rate revealed the coexistence of the two diseases. Corticosteroid treatment dramatically improved the patient's symptoms and supported the diagnosis. This case demonstrated that ankylosing spondylitis may present polymyalgia-like symptoms, and the two diseases may rarely coexist in the elderly. The coexistence of these two diseases has been rarely reported in literature. Accurate diagnosis of the two diseases is essential for improving the patient's symptoms and quality of life.

PMID- 29450877 TI - Effect of intravenous preoperative versus postoperative paracetamol on postoperative nausea and vomiting in patients undergoing strabismus surgery: A prospective randomized study. AB - OBJECTIVES: This prospective randomized study aimed to compare the efficacy of preoperative versus postoperative paracetamol on postoperative nausea and vomiting (PONV) in children undergoing strabismus surgery. METHODS: Ninety-six patients were randomly divided into three equal groups (n=32). In the preoperative paracetamol group, patients received intravenous (IV) infusion of paracetamol [15 mg kg-1 (1.5 ml kg-1)] 1 h before surgery over 20 min and that of saline (1.5 ml kg-1) in the recovery room. In the postoperative paracetamol group, patients received IV infusion of saline (1.5 ml kg-1) 1 h before surgery over 20 min and that of paracetamol [15 mg kg-1 (1.5 ml kg-1)] in therecovery room. In the control group, patients received the IV infusion of saline (1.5 ml kg-1) pre- and postoperatively. Postoperative pain condition was evaluated using the Faces Pain Scale. In the recovery room, an observer recorded the pain score, complaints of nausea and vomiting, the need for rescue analgesics, and the need for antiemetic drug during 24 h postoperatively. RESULTS: The incidence of nausea and vomiting during the first 0-6 h postoperatively was significantly lower in the preoperative paracetamol group than in the control and postoperative paracetamol groups (p<0.001). The number of patients requiring antiemetic administration during the first 0-6 and 6-12 h postoperatively was found to be higher in the control group than in the other groups (p<0.001, for all). CONCLUSION: The preoperative administration of paracetamol reduces PONV incidence in children undergoing strabismus surgery. PMID- 29450878 TI - Antepartum risk factors for moderate to severe neonatal hypoxic ischemic encephalopathy: a Swedish national cohort study. AB - INTRODUCTION: Our aim was to identify antepartum risk factors for neonatal hypoxic ischemic encephalopathy, with a focus on maternal body mass index and height. MATERIAL AND METHODS: National population-based cohort study of 692 428 live-born infants >=36 gestational weeks in Sweden, 2009-2015. Data from the Swedish Medical Birth Register and the Swedish Neonatal Quality Register were linked. Short maternal stature was defined as <=155 cm, and overweight as body mass index >=25 kg/m2 . Therapeutic hypothermia served as surrogate marker of moderate to severe hypoxic ischemic encephalopathy. Associations between maternal and infant characteristics and hypoxic ischemic encephalopathy were calculated with logistic regression analyses, and risks were presented as odds ratios with 95% confidence intervals. RESULTS: Moderate to severe hypoxic ischemic encephalopathy occurred in 0.67/1000 infants. Nulliparity, previous cesarean delivery, short stature, overweight, gestational age, occiput posterior presentation and birthweight were all independently associated with hypoxic ischemic encephalopathy. The risk of hypoxic ischemic encephalopathy increased with decreasing maternal height and increasing body mass index. Compared with non short women (>=156 cm) with normal weight (body mass index <25 kg/m2 ), those with both short stature and overweight had increased risk of hypoxic ischemic encephalopathy (odds ratio 3.66; 95% confidence intervals 2.41-5.55). Among parous women with both short stature and overweight, the risk was almost sixfold (odds ratio 5.74; 95% confidence intervals 3.41-9.66). CONCLUSIONS: Antepartum risk factors for moderate to severe hypoxic ischemic encephalopathy included nulliparity, previous cesarean delivery, short stature, overweight, gestational age, occiput posterior presentation and birthweight. The combination of maternal short stature and overweight was associated with a more than threefold risk of subsequent hypoxic ischemic encephalopathy. PMID- 29450879 TI - Genetic investigation of 93 families with microphthalmia or posterior microphthalmos. AB - Microphthalmia is a developmental eye defect that is highly variable in severity and in its potential for systemic association. Despite the discovery of many disease genes in microphthalmia, at least 50% of patients remain undiagnosed genetically. Here, we describe a cohort of 147 patients (93 families) from our highly consanguineous population with various forms of microphthalmia (including the distinct entity of posterior microphthalmos) that were investigated using a next-generation sequencing multi-gene panel (i-panel) as well as whole exome sequencing and molecular karyotyping. A potentially causal mutation was identified in the majority of the cohort with microphthalmia (61%) and posterior microphthalmos (82%). The identified mutations (55 point mutations, 15 of which are novel) spanned 24 known disease genes, some of which have not or only very rarely been linked to microphthalmia (PAX6, SLC18A2, DSC3 and CNKSR1). Our study has also identified interesting candidate variants in 2 genes that have not been linked to human diseases (MYO10 and ZNF219), which we present here as novel candidates for microphthalmia. In addition to revealing novel phenotypic aspects of microphthalmia, this study expands its allelic and locus heterogeneity and highlights the need for expanded testing of patients with this condition. PMID- 29450880 TI - A review of cutaneous manifestations within glucagonoma syndrome: necrolytic migratory erythema. AB - Necrolytic migratory erythema (NME) is a rare skin disorder that is a cutaneous manifestation of the glucagonoma syndrome. It presents with annular eruptions of migrating erythematous papules and plaques with superficial epidermal necrosis, central flaccid bullae, and crusted erosions located primarily in the intertriginous areas. Treatment with the long-acting somatostatin analog Octreotide is a potential therapy to help ameliorate skin symptoms. We present a case of a patient with a 1-year history of a pancreatic glucagonoma that developed an ulcerated, plaque-like, weeping rash over multiple areas of their body despite current treatment with Octreotide and stable pancreatic tumor staging. The patient had a similar rash when initially diagnosed with a glucagonoma, and it quickly improved after Octreotide treatment. Clinical examination and biopsy were consistent with necrolytic migratory erythema due to an underlying glucagonoma. This rare case adds to our understanding of the clinical presentation of NME, as well as highlights the relapsing and remitting course, even if the underlying pancreatic tumor is stable and the patient is undergoing treatment. PMID- 29450881 TI - A comparative description of perceived stress and coping strategies among psychology and nonpsychology students in the United Arab Emirates. AB - PURPOSE: This study describes perceived stress and coping strategies as they occur within a college-aged population from an Arab background. Variables were compared between psychology students and their peers from other faculties. DESIGN AND METHODS: A cross-sectional, correlational design was used for this study. A total of 114 students completed the Brief COPE questionnaire, the Perceived Stress Scale, and a measure of our own design to assess sources of psychosocial support. FINDINGS: The complete sample engaged in help-seeking behavior, though distinct differences between groups were evident. Perceived stress was pervasive. Students employed a range of coping strategies but showed a clear preference for emotion-focused strategies. PRACTICE IMPLICATIONS: Training institutions carry the responsibility for developing supportive interventions to promote students' throughput, and ensure the graduation of competent and ethically sound clinicians. PMID- 29450882 TI - The role of neutrophils in skin damage induced by tissue-deposited lupus IgG. AB - Skin injury is the second most common clinical manifestation in patients with systemic lupus erythematosus (SLE). Neutrophils are crucial effector cells in the immune system but the significance of neutrophils in the pathogenesis of SLE is not clear. This study is to explore the role of neutrophils in the skin damage of SLE. We used lupus-prone mice and a C57BL/6 mouse model of lupus serum IgG induced skin inflammation to investigate the role of neutrophils in skin damage of SLE. We found that a few neutrophils infiltrated the inflammatory sites of skin in lupus-prone mice and the lupus-IgG-induced skin damage mouse model. Depletion of neutrophils did not affect the development of skin inflammation caused by lupus IgG, and lupus IgG can induce apoptosis of neutrophils. The apoptosis of neutrophils induced by lupus IgG is related to FcgammaRIII and Fas/Fas ligand pathways. Our study indicates that neutrophils are not major contributors in the skin damage caused by tissue-deposited lupus IgG but death of neutrophils caused by lupus IgG may provide a resource of a large amount of autoantigens in SLE. PMID- 29450883 TI - Adolescents' Friendships, Academic Achievement, and Risk Behaviors: Same-Behavior and Cross-Behavior Selection and Influence Processes. AB - This study examined to what extent adolescents' and their friends' risk behaviors (i.e., delinquency and alcohol use) hinder or promote their academic achievement (grade point average [GPA]), and vice versa. Longitudinal data were used (N = 1,219 seventh- to ninth-grade adolescents; Mage = 13.69). Results showed that risk behaviors negatively affected adolescents' GPA, whereas GPA protected against engaging in risk behaviors. Moreover, adolescents tended to select friends who have similar behaviors and friends' behaviors became more similar over time (same-behavior selection and influence). Furthermore, although same behavior effects seemed to dominate, evidence was found for some cross-behavior selection effects and a tendency in seventh grade for cross-behavior influence effects. Concluding, it is important to investigate the interplay between different behaviors with longitudinal social network analysis. PMID- 29450884 TI - Is sonographically measured cervical length at 37 weeks of gestation associated with intrapartum cesarean section? A prospective cohort study. AB - INTRODUCTION: Cesarean section rates continue to increase globally. Prediction of intrapartum cesarean section could lead to preventive measures. Our aim was to assess the association between sonographically measured cervical length at 37 weeks of gestation and cesarean section among women planning a vaginal birth. The population was women with a low-risk pregnancy or with gestational diabetes. MATERIAL AND METHODS: This was a prospective cohort study conducted in a tertiary referral hospital in Sydney, Australia. In all, 212 women with a low-risk pregnancy or with gestational diabetes were recruited including 158 nulliparous and 54 parous women. Maternal demographic, clinical and ultrasound characteristics were collected at 37 weeks of gestation. Semi-Bayesian logistic regression and Markov chain Monte Carlo simulation were used to assess the relation between cervical length and cesarean section in labor. RESULTS: Rates of cesarean section were 5% (2/55) for cervical length <=20 mm, 17% (17/101) for cervical length 20-32 mm, and 27% (13/56) for cervical length >32 mm. These rates were 4, 22 and 33%, respectively, in nulliparous women. In the semi-Bayesian analysis, the odds ratio for cesarean section was 6.2 (95% confidence interval 2.2-43) for cervical length 20-32 mm and 10 (95% confidence interval 4.8-74) for cervical length >32 mm compared with the lowest quartile of cervical length, after adjusting for maternal age, parity, height, prepregnancy body mass index, gestational diabetes, induction of labor, neonatal sex and birthweight centile. CONCLUSIONS: Cervical length at 37 weeks of gestation is associated with intrapartum cesarean section. PMID- 29450885 TI - Loser! On the combined impact of emotional and person-descriptive word meanings in communicative situations. AB - Humans have a unique capacity to induce intense emotional states in others by simple acts of verbal communication, and simple messages such as bad can elicit strong emotions in the addressee. However, up to now, research has mainly focused on general emotional meaning aspects and paradigms of low personal relevance (e.g., word reading), thereby possibly underestimating the impact of verbal emotion. In the present study, we recorded ERPs while presenting emotional words differing in word-inherent person descriptiveness (in that they may or may not refer to or describe a person; e.g., winner vs. sunflower). We predicted stronger emotional responses to person-descriptive words. Additionally, we enhanced the relevance of the words by embedding them in social-communicative contexts. We observed strong parallels in the characteristics of emotion and descriptiveness effects, suggesting a common underlying motivational basis. Furthermore, word inherent person descriptiveness affected emotion processing at late elaborate stages reflected in the late positive potential, with emotion effects found only for descriptive words. The present findings underline the importance of factors determining the personal relevance of emotional words. PMID- 29450886 TI - Theoretical and experimental determination of scaling factors in electron dosimetry for 3D-printed polylactic acid. AB - PURPOSE: Plastic phantoms are commonly used in daily routine for dosimetric tasks in radiation therapy. Although water is the reference medium according to the dosimetric protocols, measurements with nonwater phantoms are easier to be performed. To succeed absorbed dose determination, certain scaling factors have to be applied to the acquired measurements. Taking into account the increased availability of three-dimensional (3D) printing, we attempted to obtain scaling factors for polylactic acid (PLA), a commonly used thermoplastic material for 3D printing. METHODS: Measurements were performed with a custom-made phantom from PLA material, which was designed and constructed using 3D printing technology. Depth and fluence scaling factors were obtained within the range of 6 to 20 MeV. Moreover, Monte Carlo simulations were performed to verify the measured results. RESULTS: Experimental and Monte Carlo (MC) values showed a good agreement, especially in lower energies. Mean value of depth scaling factor (cpl ) over the whole range of energies was 0.946, while mean fluence scaling factor (hpl ) was found to be 1.050. For energies below 10 MeV, the corresponding mean values for cpl and hpl were 0.946 and 1.054, respectively. CONCLUSIONS: PLA phantoms could be constructed and used for electron beam nonreference measurements, reproducing even more complex geometries, from simple quality assurance devices to geometrically complicated anthropomorphic phantoms. PMID- 29450887 TI - Linear yellow papules following a cat scratch. PMID- 29450888 TI - Spatiotemporal heterogeneity in prey abundance and vulnerability shapes the foraging tactics of an omnivore. AB - Prey abundance and prey vulnerability vary across space and time, but we know little about how they mediate predator-prey interactions and predator foraging tactics. To evaluate the interplay between prey abundance, prey vulnerability and predator space use, we examined patterns of black bear (Ursus americanus) predation of caribou (Rangifer tarandus) neonates in Newfoundland, Canada using data from 317 collared individuals (9 bears, 34 adult female caribou, 274 caribou calves). During the caribou calving season, we predicted that landscape features would influence calf vulnerability to bear predation, and that bears would actively hunt calves by selecting areas associated with increased calf vulnerability. Further, we hypothesized that bears would dynamically adjust their foraging tactics in response to spatiotemporal changes in calf abundance and vulnerability (collectively, calf availability). Accordingly, we expected bears to actively hunt calves when they were most abundant and vulnerable, but switch to foraging on other resources as calf availability declined. As predicted, landscape heterogeneity influenced risk of mortality, and bears displayed the strongest selection for areas where they were most likely to kill calves, which suggested they were actively hunting caribou. Initially, the per-capita rate at which bears killed calves followed a type-I functional response, but as the calving season progressed and calf vulnerability declined, kill rates dissociated from calf abundance. In support of our hypothesis, bears adjusted their foraging tactics when they were less efficient at catching calves, highlighting the influence that predation phenology may have on predator space use. Contrary to our expectations, however, bears appeared to continue to hunt caribou as calf availability declined, but switched from a tactic of selecting areas of increased calf vulnerability to a tactic that maximized encounter rates with calves. Our results reveal that generalist predators can dynamically adjust their foraging tactics over short time-scales in response to changing prey abundance and vulnerability. Further, they demonstrate the utility of integrating temporal dynamics of prey availability into investigations of predator-prey interactions, and move towards a mechanistic understanding of the dynamic foraging tactics of a large omnivore. PMID- 29450889 TI - Olive (Olea europaea) leaf extract alters the cytokine profile of Leishmania major-infected macrophages: New insight into the underlying mechanism. AB - This study aimed to identify the effects of olive leaf extract (OLE) on IFNgamma, TNFalpha, TGFbeta and nitric oxide (NO) resulted from macrophages infected with Leishmania major (L. major) amastigotes in the culture medium. High-performance liquid chromatography (HPLC) was used to analyse the level of Oleuropein in plant extract. To evaluate the immunomodulatory effects of OLE, the isolated BALB/c mice peritoneal macrophages were infected with L. major promastigotes and treated with 6.25, 12.5 and 25 MUg/mL concentrations of OLE. To assess the cytokines, supernatants of cell cultures were harvested after 12, 24 and 48 hours. Cytokine production was evaluated by ELISA. Nitrite accumulation in the culture medium was assessed using the Griess reaction. The level of Oleuropein in the extract was 18.45% by HPLC. According to results, the production of IFNgamma and TNFalpha was significantly increased when the infected and/or not infected macrophages with L. major promastigotes were affected by different concentrations of OLE. Conversely, the production of TGFbeta was significantly decreased under the same conditions. Furthermore, the colorimetric determination of NO accumulation in the culture medium indicated that OLE has no effect on NO production. The study corroborates the immunomodulatory effects of OLE on L. major-infected macrophages. PMID- 29450890 TI - Efficacy and safety of eslicarbazepine acetate monotherapy in patients converting from carbamazepine. AB - OBJECTIVE: To evaluate the influence of prior use of carbamazepine (CBZ) and other antiepileptic drugs (AEDs) with a putatively similar mechanism of action (inhibition of voltage-gated sodium channels; VGSCs) on seizure outcomes and tolerability when converting to eslicarbazepine acetate (ESL), using data pooled from 2 controlled conversion-to-ESL monotherapy trials (studies: 093-045, 093 046). METHODS: Adults with treatment-resistant focal (partial-onset) seizures were randomized 2:1 to ESL 1600 or 1200 mg once daily. The primary efficacy endpoint was study exit (meeting predefined exit criteria related to worsening seizure control) versus an historical control group. Other endpoints included change in seizure frequency, responder rate, and tolerability. Endpoints were analyzed for subgroups of patients who received CBZ (or any VGSC inhibitor [VGSCi]) during baseline versus those who received other AEDs. RESULTS: Of 365 patients in the studies, 332 were evaluable for efficacy. The higher risk of study exit in the subgroups that received CBZ (or any VGSCi) during baseline, versus other AEDs, was not statistically significant (hazard ratios were 1.49 for +CBZ vs -CBZ [P = .10] and 1.27 for +VGSCi vs. -VGSCi [P = .33]). Reductions in seizure frequency and responder rates were lower in patients who converted from CBZ or other VGSCi compared with those who converted from other AEDs. There were no notable differences in overall tolerability between subgroups, but the incidence of some adverse events (eg, dizziness, somnolence, nausea) differed between subgroups and/or between treatment periods. SIGNIFICANCE: Baseline use of CBZ or other major putative VGSC inhibitors did not appear to significantly increase the risk of study exit due to worsening seizure control, or to increase the frequency of side effects when converting to ESL monotherapy. However, bigger improvements in efficacy may be possible in patients converting to ESL monotherapy from an AED regimen that does not include a VGSC inhibitor. PMID- 29450891 TI - A public health approach for preventing neural tube defects: folic acid fortification and beyond. AB - In this paper we review the evidence basis for prevention of folic acid-sensitive neural tube defects (NTDs) through public health interventions in women of reproductive age (WRA), the proven vehicles for delivery of folic acid, and what is needed to effectively scale these, and provide a snapshot of potential innovations that require future research. Our primary focus is on the global situation affecting large-scale food fortification (LSFF) with folic acid, in particular the fortification of wheat flour and maize meal. Our overarching conclusion is that folic acid fortification is an evidence-based intervention that reduces the prevalence of NTDs, and that LSFF with folic acid is underutilized. Thus, food fortification with folic acid should be a component of most national public health strategies, in particular where folate status is insufficient and a fortifiable food vehicle, processed by a centralized industry, is consumed regularly by WRA. The evidence shows that there is still much work needed (1) to build the enabling environment and expand programs where there is currently no legislation, (2) to improve the low quality of delivery of existing programs, and (3) to measure and sustain programs by generating new coverage data and demonstrating evidence of impact in low- and middle-income countries. PMID- 29450892 TI - Rat choice in rapidly changing concurrent schedules. AB - In two experiments, experimentally naive rats were trained in concurrent variable interval schedules in which the reinforcer ratios changed daily according to a pseudorandom binary sequence. In Experiment 1, relative response rates showed clear sensitivity to current-session reinforcer ratios, but not to previous sessions' reinforcer ratios. Within sessions, sensitivity to the current session's reinforcement rates increased steadily, and by session end, response ratios approached matching to the current-session reinforcer ratios. Across sessions, sensitivity to the current session's reinforcer ratio decreased with continued exposure to the pseudorandom binary sequence, contrary to expectations based on previous studies demonstrating learning sets. Using a second group of naive rats, Experiment 2 replicated the main results from Experiment 1 and showed that although there were increases over sessions in both changeover rate and response rate during the changeover delay, neither could explain the accompanying reductions in sensitivity. We consider the role of reinforcement history, showing that our results can be simulated using two separate representations, one local and one nonlocal, but a more complex approach will be needed to bring together these results and other history effects such as learning sets and spontaneous recovery. PMID- 29450893 TI - Dofetilide for suppression of atrial fibrillation in hypertrophic cardiomyopathy: A case series and literature review. AB - BACKGROUND: Limited medical options are available for rhythm control in patients with atrial fibrillation (AF) and hypertrophic cardiomyopathy (HCM). There are no published reports of dofetilide use in this population. METHODS: A retrospective chart review was conducted on 1,404 patients loaded on dofetilide for AF suppression at the Cleveland Clinic from 2008 to 2012, 25 of whom were found to have HCM. RESULTS: The HCM cohort was 32% female, 76% with persistent AF, mean age of 59 +/- 10 years, and mean ejection fraction of 54 +/- 9 %. Of the 25 patients, 21 were discharged on dofetilide, three discontinued during loading due to QTc prolongation, and one due to inefficacy. There were no adverse events during loading. Of those discharged on dofetilide, 11/21 (52%) were still on it at a median follow-up of 396 (198, 699) days at the time of the chart review. For those in whom it was discontinued, the median time on the drug was 301 (111, 738) days. Of the 10 patients who discontinued dofetilide during follow-up, six were due to inefficacy, one postablation, one postheart transplant, one due to death secondary to lung cancer, and one due to worsening edema. CONCLUSIONS: Dofetilide was well tolerated in this group of patients with AF and HCM and it facilitated management of AF in 21/25 (84%) patients. Further research is needed to assess the safety and efficacy of dofetilide in order to develop evidence-based guidelines for the pharmacological management of AF in this population. PMID- 29450894 TI - Assessment of the correlations of lacosamide concentrations in saliva and serum in patients with epilepsy. AB - Therapeutic drug monitoring of antiepileptic drugs is based on patient serum samples. In this study, we evaluated the correlation between lacosamide (LCM) steady state concentrations in serum and saliva samples. Additionally, we investigated the relation with daily dose, and assessed the feasibility of saliva collection. This was an open-label, single center study including data from 25 patients at the Bethel Epilepsy Center treated with LCM (50-650 mg/d). Samples were collected in the morning (fasting values) and in selected cases at 50 minutes to 5 hours after the morning dose. Nonsignificant differences in the mean LCM morning (trough) concentration in serum and saliva were observed. Serum and saliva concentrations across all samples were highly correlated, (r = .874), with a slightly lower correlation when only fasting values were analyzed (r = .860). Higher correlation with daily dosages was observed in serum samples (r = .773) than in saliva samples (r = .604). Serum and saliva concentrations increased significantly after intake of the LCM morning dose (P < .001). The median absolute and percentage increase of LCM in serum were moderately lower than in saliva samples, with a few outliers in saliva samples. Consequently, saliva could offer great clinical potential to monitor drug concentrations and guide LCM treatment in epileptic patients. PMID- 29450895 TI - A Test of Multisession Automatic Action Tendency Retraining to Reduce Alcohol Consumption Among Young Adults in the Context of a Human Laboratory Paradigm. AB - BACKGROUND: Young adult heavy drinking is an important public health concern. Current interventions have efficacy but with only modest effects, and thus, novel interventions are needed. In prior studies, heavy drinkers, including young adults, have demonstrated stronger automatically triggered approach tendencies to alcohol-related stimuli than lighter drinkers. Automatic action tendency retraining has been developed to correct this tendency and consequently reduce alcohol consumption. This study is the first to test multiple iterations of automatic action tendency retraining, followed by laboratory alcohol self administration. METHODS: A total of 72 nontreatment-seeking, heavy drinking young adults ages 21 to 25 were randomized to automatic action tendency retraining or a control condition (i.e., "sham training"). Of these, 69 (54% male) completed 4 iterations of retraining or the control condition over 5 days with an alcohol drinking session on Day 5. Self-administration was conducted according to a human laboratory paradigm designed to model individual differences in impaired control (i.e., difficulty adhering to limits on alcohol consumption). RESULTS: Automatic action tendency retraining was not associated with greater reduction in alcohol approach tendency or less alcohol self-administration than the control condition. The laboratory paradigm was probably sufficiently sensitive to detect an effect of an experimental manipulation given the range of self-administration behavior observed, both in terms of number of alcoholic and nonalcoholic drinks and measures of drinking topography. CONCLUSIONS: Automatic action tendency retraining was ineffective among heavy drinking young adults without motivation to change their drinking. Details of the retraining procedure may have contributed to the lack of a significant effect. Despite null primary findings, the impaired control laboratory paradigm is a valid laboratory-based measure of young adult alcohol consumption that provides the opportunity to observe drinking topography and self-administration of nonalcoholic beverages (i.e., protective behavioral strategies directly related to alcohol use). PMID- 29450897 TI - Molecular imprinted polymers based on magnetic chitosan with different deep eutectic solvent monomers for the selective separation of catechins in black tea. AB - Two types of molecular-imprinted polymers-based magnetic chitosan with facile deep eutectic solvent-functional monomers (Fe3 O4 -CTS@DES-MIPs) were synthesized and applied as adsorbents in magnetic solid-phase extraction (MSPE) for the selective recognition and separation of (+)-catechin, (-)-epicatechin, and (-) epigallocatechin gallate in black tea. The obtained Fe3 O4 -CTS@DES-MIPs were characterized by Fourier transform infrared spectroscopy and field emission scanning electron microscopy. The selective recognition ability was examined by adsorption experiments. The actual amounts of (+)-catechin, (-)-epicatechin, and (-)-epigallocatechin gallate extracted from black tea using Fe3 O4 -CTS@DES-MIPs by the MSPE method were 13.10, 6.32, and 8.76 mg/g, respectively. In addition, the magnetic Fe3 O4 -CTS@DES-MIPs showed outstanding recognition and selectivity. Therefore, it can be used to separate bioactive compounds from black tea. The new type of DES adopted as the functional monomer in this paper provides a new perspective for the recognition and separation of bioactive compounds.

AB - Computational investigation of the photochemical properties of transition-metal centered dyes typically involves optimization of the molecular structure followed by calculation of the UV/visible spectrum. At present, these steps are usually carried out using density functional theory (DFT) and time-dependent DFT calculations. Recently, we demonstrated that semiempirical methods with appropriate parameterization could yield geometries that were in very good agreement with DFT calculations, allowing large sets of molecules to be screened quickly and efficiently. In this article, we modify a configuration interaction (CI) method based on a semiempirical PM6 Hamiltonian to determine the UV/visible absorption spectra of Ru-centered complexes. Our modification to the CI method is based on a scaling of the two-center, two-electron Coulomb integrals. This modified, PM6-based method shows a significantly better match to the experimental absorption spectra versus the default configuration interaction method (in MOPAC) on a training set of 13 molecules. In particular, the modified PM6 method blue shifts the location of the metal-to-ligand charge-transfer (MLCT) peaks, in better agreement with experimental and DFT-based computational results, correcting a significant deficiency of the unmodified method.

AB - Heavy use of alcohol can lead to addictive behaviors and to eventual alcohol related tissue damage. While increased consumption of alcohol has been attributed to various factors including level of alcohol exposure and environmental factors such as stress, data from behavioral scientists and physiological researchers are revealing roles for the circadian rhythm in mediating the development of behaviors associated with alcohol use disorder as well as the tissue damage that drives physiological disease. In this work, we compile recent work on the complex mutually influential relationship that exists between the core circadian rhythm and the pharmacodynamics of alcohol. As we do so, we highlight implications of the relationship between alcohol and common circadian mechanisms of effected organs on alcohol consumption, metabolism, toxicity, and pathology. PMID- 29450902 TI - Identification and expression profiles of novel odorant binding proteins and functional analysis of OBP99a in Bactrocera dorsalis. AB - Odorant-binding proteins (OBPs) in insects are essential for mating and oviposition host selection. How these OBPs respond to different hosts at the mRNA level and their effects on behavior remain poorly characterized. The oriental fruit fly Bactrocera dorsalis is a highly invasive agricultural pest with an extremely broad host range and high fecundity. Based on our previously constructed B. dorsalis transcriptome, six OBPs that were differentially expressed during three different physiological adult stages were identified. A phylogenetic tree was constructed to illustrate the relationships of these six OBPs with OBP sequences from three other dipteran species (Drosophila melanogaster, Anopheles gambiae, and Ceratitis capitata). The spatiotemporal expression profiles of the six OBPs were analyzed using quantitative real-time PCR. Our results revealed that OBP19c, OBP44a, OBP99a, and OBP99d were abundantly expressed from the prepupa stage to the adult stage, and most of the OBPs were mainly expressed in the head, wings, and antennae. The expression levels of these OBPs were upregulated when female flies were exposed to their preferred hosts. Silencing OBP99a resulted fewer eggs being laid compared with the control group when the females were exposed to their preferred host, that is, banana, whereas more eggs were laid when a non-preferred host, that is, tomato, was used. Furthermore, silencing OBP99a led to sexually dimorphic mating behavior. dsOBP99a injected males dramatically reduced courtship, whereas enhanced courtship was observed in the treated females. These data indicate that OBPs may participate in different biological processes of B. dorsalis. Our study will provide insight into the molecular mechanism of chemoreception and help develop ecologically friendly pest-control strategies. PMID- 29450903 TI - Extended physical education in children aged 6-15 years was associated with improved academic achievement in boys. AB - AIM: Physical activity (PA) has been associated with enhanced cognition, brain development and concentration. This study evaluated whether increased physical education (PE) improved academic achievement. METHODS: We recruited 304 children (55% boys) from a Swedish school in Skane County in 1998-2002 when they were six to seven years of age and followed them through all nine mandatory school years. Their PE level was increased from 60 to 200 minutes per week, and their results were compared with 73 885 control children (51% boys) in the county who graduated in the same years and did the standard 60 minutes of PE per week. Their academic achievements were measured as their final grade scores and the proportion of students eligible for upper secondary school. RESULTS: The eligibility for further education increased in the intervention boys by 6.8 percentage points and the mean grade score by 12.1 points, while in the control group as a whole, the eligibility rate decreased by 0.7 percentage points and the mean grade score increased by 1.7 points. No changes in eligibility rates or mean grade scores were seen in the intervention girls. CONCLUSION: Increasing weekly PE over nine years was associated with improved academic achievement in boys. PMID- 29450904 TI - Pt-Co nanocluster in hollow carbon nanospheres. AB - Recently, it has been reported that small Pt/Co bimetallic nanoclusters into hollow carbon spheres (HCS) show outstanding catalytic performances in deriving biomass fuels due to the small particle size and the homogeneous alloying. Thus, the knowledge about the thermal evolution and stability of the nanoclusters into the HCS has a great importance. We have simulated the heating process beyond the melting point for the bare and encapsulated Pt/Co clusters into the HCS with the different sizes of 55, 147, and 309. The different thermodynamic and structural properties of the nanoclusters have also been investigated in this work. Our results show that the nanoclusters are more stable into the HCS than the bare clusters. The melting points of the supported clusters are also higher than the unsupported clusters. The confined nanoclusters have also lower excess energy values than the bare clusters which means that the encapsulation of Pt/Co nanoclusters into the HCS is favorable. The structural investigations show that a core-shell structure cannot be observed for the different supported and unsupported clusters and the initial mixed structure of the different nanoclusters remains also at the melting points. To more investigate this claim, the radial chemical distribution function (RCDF) and radial distribution function (RDF) of the bare and encapsulated clusters have also been calculated and discussed.

AB - BACKGROUND: Patients with advanced prostate cancer have limited curative options, therefore new treatments are needed. Mouse models play a pivotal role in the discovery and development of new treatments. In the present study, a TRAMP derived Orthotopic Prostate Syngeneic (TOPS) mouse model was developed and found to provide a consistent means of monitoring tumor and metastatic responses to novel treatments. METHODS: The mouse TOPS model was generated using luciferase transduced TRAMP-C2 prostate cancer cells that were orthotopically injected into Bl6 mice by ultrasound guidance. Tumor growth and development was monitored using ultrasound and bioluminescence imaging. RESULTS: Tumors and metastases were consistently established and increases in tumor size correlated with increases in bioluminescence. In addition, when mice with an established tumor were castrated, tumor progression mirrored clinical progression. We further treated the TOPS model with an oncolytic Herpes Simplex virus and showed that we were able to monitor the therapeutic effect of the orthotopic tumor after virus treatment through IVIS imaging system. CONCLUSION: We have developed a powerful animal model to advance the current selection of effective treatments for patients with advanced prostate cancer.

AB - Eastern grey kangaroos (Macropus giganteus) younger than 19 months at Kanazawa Zoological Gardens, Japan, frequently died of enteritis. The main cause of death was coccidiosis. This study aimed to reveal retrospectively the clinical features of enteritis and factors contributing to its high occurrence. In addition, haematological and serum biochemical parameters in kangaroos younger than 24 months were analyzed. The findings suggested that enteritis occurrence was higher in 10- to 12-month-old kangaroos than other ages and during seasons with high temperature and humidity than during seasons with low temperature and humidity. The haematological and serum biochemical analyses showed decreases in glucose, total cholesterol, calcium, and triglyceride levels at approximately 10 months of age. Joeys emerge from their mother's pouch at 8 months of age and permanently leave it at approximately 10 months of age. Subsequently, the joeys are exposed to the external environment and infectious agents. Although the joeys continue suckling until 13-19 months of age, the joeys start to eat the similar feed to the adult and their nutritional status may change at approximately 10 months of age. Seasonal influences, species behavior, and shifts in dietary composition are proposed to be contributory to the increased occurrence of enteritis between 10 and 12 months of age. PMID- 29450907 TI - Molecular dynamics study of taxadiene synthase catalysis. AB - Molecular dynamics (MD) simulations have been performed to study the dynamic behavior of noncovalent enzyme carbocation complexes involved in the cyclization of geranylgeranyl diphosphate to taxadiene catalyzed by taxadiene synthase (TXS). Taxadiene and the observed four side products originate from the deprotonation of carbocation intermediates. The MD simulations of the TXS carbocation complexes provide insights into potential deprotonation mechanisms of such carbocations. The MD results do not support a previous hypothesis that carbocation tumbling is a key factor in the deprotonation of the carbocations by pyrophosphate. Instead water bridges are identified which may allow the formation of side products via multiple proton transfer reactions. A novel reaction path for taxadiene formation is proposed on the basis of the simulations. (c) 2018 Wiley Periodicals, Inc.

PMID- 29450909 TI - Nature of hydration shells of a polyoxy-anion with a large cationic centre: The case of iodate ion in water. AB - The structural nature of the solvation shells of an iodate ion, which is known to be a polyoxy-anion with a large cationic centre, is investigated by means of Born Oppenheimer molecular dynamics (BOMD) simulations using BLYP and the dispersion corrected BLYP-D3 functionals. The iodate ion is found to have two distinct solvation regions around the positively charged iodine (iodine solvation shell or ISS) and the negatively charged oxygens (oxygen solvation shell or OSS). We have looked at the spatial, orientational, and hydrogen bond distributions of water in the two solvation regions. It is found that the water orientational profile in the ISS is typical of a cation hydration shell. The hydrogen bonded structure of water in the OSS is found to be very similar to that of the bulk water structure. Thus, the iodate ion essentially behaves like a positively charged iodine ion in water as if there is no anionic part. This explains why the cationic character of the iodate ion was prominently seen in earlier studies. The arrangement of water molecules in the two solvation shells and in the intervening regions around the iodate ion is further resolved by looking at structural cross-correlations. The electronic properties of the solvation shells are also looked at by calculating the solute-solvent orbital overlap and dipole moments of the solute and solvation shell water. We have also performed BOMD simulations of iodate ion-water clusters at experimentally relevant conditions. The simulation results are found to be in agreement with experimental results.

AB - Cross-sectional studies have shown that exposure to indoor moisture damage and mold may be associated with subclinical inflammation. Our aim was to determine whether early age exposure to moisture damage or mold is prospectively associated with subclinical systemic inflammation or with immune responsiveness in later childhood. Home inspections were performed in children's homes in the first year of life. At age 6 years, subclinical systemic inflammation was measured by serum C-reactive protein (CRP) and blood leukocytes and immune responsiveness by ex vivo production of interleukin 1-beta (IL-1beta), IL-6, and tumor necrosis factor alpha (TNF-alpha) in whole blood cultures without stimulation or after 24 hours stimulation with phorbol 12-myristate 13-acetate and ionomycin (PI), lipopolysaccharide (LPS), or peptidoglycan (PPG) in 251-270 children. Moisture damage in child's main living areas in infancy was not significantly associated with elevated levels of CRP or leukocytes at 6 years. In contrast, there was some suggestion for an effect on immune responsiveness, as moisture damage with visible mold was positively associated with LPS-stimulated production of TNF alpha and minor moisture damage was inversely associated with PI-stimulated IL 1beta. While early life exposure to mold damage may have some influence on later immune responsiveness, it does not seem to increase subclinical systemic inflammation in later life.

PMID- 29450912 TI - Association of clinicopathological features of melanoma with total naevus count and a history of dysplastic naevi: a cross-sectional retrospective study within an academic centre. AB - BACKGROUND: High naevus count (HNC) (>= 50 naevi) and presence of dysplastic naevi (DN) are risk factors for malignant melanoma (MM); however, MMs also occur in patients with low naevus count (LNC) (< 50 naevi) and in patients without DN. Little is known about differences between MMs in these groups. AIM: To characterize the clinicopathological differences between MMs in patients with HNC and those in patients with LNC, with or without biopsy-proven DN. METHODS: This was a cross-sectional retrospective chart review of 281 patients with MM seen between April 2013 and March 2014 at an academic pigmented lesion clinic (Boston, MA, USA). RESULTS: Patients with LNC MMs were diagnosed at an older age (51 vs. 41 years, P < 0.001, OR = 0.95, 95% CI 0.93-0.97), with more aggressive MM features, including greater Breslow thickness (1.1 vs. 0.8 mm, P = 0.01), more mitoses (2 vs. 1 mitoses/mm2 , P < 0.001), lower rate of superficial spreading subtype (58 vs. 78%, P < 0.01, OR = 2.57, 95% CI 1.31-5.03) and higher MM stage (P < 0.001), compared to patients with HNC. Patients with DN had similar trends as those in patients with HNC described above, and in addition, were more likely to have a truncal MM (55 vs. 39%, P < 0.01, OR = 1.97, 95% CI 1.22-3.18) with less ulceration (13 vs. 29%, P < 0.01, OR = 0.36, 95% CI 0.19-0.71). Patients without DN were more likely to have a history of a non-MM skin cancer (32 vs. 19%, P = 0.01, OR = 0.49, 95% CI 0.28-0.85) and an amelanotic MM (33 vs 21%, P = 0.03, OR = 0.55, 95% CI 0.31-0.96). CONCLUSIONS: Patients with LNC may develop MMs with more aggressive features at an older age than patients with HNC. A history of biopsy-proven DN reveals distinct MM differences compared to patients without DN. PMID- 29450913 TI - In Situ Repair of 2D Chalcogenides under Electron Beam Irradiation. AB - Molybdenum disulfide (MoS2 ) and bismuth telluride (Bi2 Te3 ) are the two most common types of structures adopted by 2D chalcogenides. In view of their unique physical properties and structure, 2D chalcogenides have potential applications in various fields. However, the excellent properties of these 2D crystals depend critically on their crystal structures, where defects, cracks, holes, or even greater damage can be inevitably introduced during the preparation and transferring processes. Such defects adversely impact the performance of devices made from 2D chalcogenides and, hence, it is important to develop ways to intuitively and precisely repair these 2D crystals on the atomic scale, so as to realize high-reliability devices from these structures. Here, an in situ study of the repair of the nanopores in MoS2 and Bi2 Te3 is carried out under electron beam irradiation by transmission electron microscopy. The experimental conditions allow visualization of the structural dynamics of MoS2 and Bi2 Te3 crystals with unprecedented resolution. Real-time observation of the healing of defects at atomic resolution can potentially help to reproducibly fabricate and simultaneously image single-crystalline free-standing 2D chalcogenides. Thus, these findings demonstrate the viability of using an electron beam as an effective tool to precisely engineer materials to suit desired applications in the future. PMID- 29450914 TI - Graphene and Carbon-Nanotube Nanohybrids Covalently Functionalized by Porphyrins and Phthalocyanines for Optoelectronic Properties. AB - In recent years, there has been a rapid growth in studies of the optoelectronic properties of graphene, carbon nanotubes (CNTs), and their derivatives. The chemical functionalization of graphene and CNTs is a key requirement for the development of this field, but it remains a significant challenge. The focus here is on recent advances in constructing nanohybrids of graphene or CNTs covalently linked to porphyrins or phthalocyanines, as well as their application in nonlinear optics. Following a summary of the syntheses of nanohybrids constructed from graphene or CNTs and porphyrins or phthalocyanines, explicit intraconjugate electronic interactions between photoexcited porphyrins/phthalocyanines and graphene/CNTs are introduced classified by energy transfer, electron transfer, and charge transfer, and their optoelectronic applications are also highlighted. The major current challenges for the development of covalently linked nanohybrids of porphyrins or phthalocyanines and carbon nanostructures are also presented. PMID- 29450915 TI - Polymer Vesicles: Modular Platforms for Cancer Theranostics. AB - As an emerging field that is receiving an increasing amount of interest, theranostics is becoming increasingly important in the field of nanomedicine. Among the various smart platforms that have been proposed for use in theranostics, polymer vesicles (or polymersomes) are among the most promising candidates for integration of designated functionalities and modalities. Here, a brief summary of typical theranostic platforms is presented with a focus on modular polymer vesicles. To highlight modularity, the different methodologies for designing therapeutic and diagnostic modules are classified and current examples of theranostic vesicles that excel in both performance and design principle are provided. Finally, future prospects for theranostic polymer vesicles that can be readily prepared with functional modules are proposed. Overall, theranostic polymer vesicles with modular modalities and functions are more promising in nanomedicine than simply being "over-engineered".

AB - Chiral molecules are of great importance in the life science since individual enantiomers may differ in biological activity, mechanism, and toxicity, making it necessary to explore efficient chiral analysis methods. Chromatography approaches are often used to differentiate enantiomers while mass spectrometry (MS) was thought to be blind in chiral analysis. With the development of MS technique, it began to play a more and more crucial part in chiral observation. In this review, we will give a detailed introduction of the analysis methods related to MS for chiral drugs, including its mechanism, applications, and future development. PMID- 29450917 TI - Factors predictive of the onset and duration of action of local anesthesia in mandibular third-molar surgery: a prospective study. AB - The aim of this study was to assess the influence of patients' and surgical variables on the onset and duration of action of local anesthesia (LA) in mandibular third-molar (M3) surgery. Patients scheduled for mandibular M3 surgery were considered for inclusion in this prospective cohort study. Patients' and surgical variables were recorded. Two per cent (2%) lidocaine with 1:100,000 epinephrine was used to block the nerves for extraction of mandibular M3. Then, the onset of action and duration of LA were monitored. Univariate analysis and multivariate regression analysis were used to analyze the data. The final cohort included 88 subjects (32 men and 56 women; mean age +/- SD = 29.3 +/- 12.3 yr). With univariate analysis, age, gender, body mass index (BMI), smoking quantity and duration, operation time, and 'volume of local anesthetic needed' significantly influenced the onset of action and duration of LA. Multivariate regression revealed that age and smoking quantity were the only statistically significant predictors of the onset of action of LA, whereas age, smoking quantity, and 'volume of local anesthetic needed' were the only statistically significant predictors of duration of LA. Further studies are recommended to uncover other predictors of the onset of action and duration of LA. PMID- 29450918 TI - Nanoalloy Materials for Chemical Catalysis. AB - Nanoalloys (NAs), which are distinctly different from bulk alloys or single metals, take on intrinsic features including tunable components and ratios, variable constructions, reconfigurable electronic structures, and optimizable performances, which endow NAs with fascinating prospects in the catalysis field. Here, the focus is on NA materials for chemical catalysis (except photocatalysis or electrocatalysis). In terms of composition, NA systems are divided into three groups, noble metal, base metal, and noble/base metal mixed NAs. Their design and fabrication for the optimization of catalytic performance are systematically summarized. Additionally, the correlations between the composition/structure and catalytic properties are also mentioned. Lastly, the challenges faced in current research are discussed, and further pathways toward their development are suggested. PMID- 29450919 TI - Looking into the Future: Toward Advanced 3D Biomaterials for Stem-Cell-Based Regenerative Medicine. AB - Stem-cell-based therapies have the potential to provide novel solutions for the treatment of a variety of diseases, but the main obstacles to such therapies lie in the uncontrolled differentiation and functional engraftment of implanted tissues. The physicochemical microenvironment controls the self-renewal and differentiation of stem cells, and the key step in mimicking the stem cell microenvironment is to construct a more physiologically relevant 3D culture system. Material-based 3D assemblies of stem cells facilitate the cellular interactions that promote morphogenesis and tissue organization in a similar manner to that which occurs during embryogenesis. Both natural and artificial materials can be used to create 3D scaffolds, and synthetic organic and inorganic porous materials are the two main kinds of artificial materials. Nanotechnology provides new opportunities to design novel advanced materials with special physicochemical properties for 3D stem cell culture and transplantation. Herein, the advances and advantages of 3D scaffold materials, especially with respect to stem-cell-based therapies, are first outlined. Second, the stem cell biology in 3D scaffold materials is reviewed. Third, the progress and basic principles of developing 3D scaffold materials for clinical applications in tissue engineering and regenerative medicine are reviewed.

PMID- 29450921 TI - Sexual Minority Adults: A National Survey on Depression, Religious Fundamentalism, Parent Relationship Quality & Acceptance. AB - Sexual minority persons from religious families may experience low acceptance by parents, however, little is known about the relationship of religiosity and parent relationships on mental health into adulthood. This study sought to test a moderated mediation model predicting depression based on religious fundamentalism, parent acceptance, and parent-child relationship quality. Sexual minority adult participants (n = 384) from across the U.S. completed a web-based, anonymous survey. Results found a conditional indirect effect of religious fundamentalism on depression through parent acceptance with the parent-child relationship quality moderating the relationship between parent acceptance and depression. This was significant up to age 52. Clinical implications and future research with sexual minority adults and their families are explored. PMID- 29450922 TI - Anisotropic Thermal and Guest-Induced Responses of an Ultramicroporous Framework with Rigid Linkers. AB - The interdependent effects of temperature and guest uptake on the structure of the ultramicroporous metal-organic framework [Cu3 (cdm)4 ] (cdm=C(CN)2 (CONH2 )- ) were explored in detail by using in situ neutron scattering and density functional theory calculations. The tetragonal lattice displays an anisotropic thermal response related to a hinged "lattice-fence" mechanism, unusual for this topology, which is facilitated by pivoting of the rigid cdm anion about the Cu nodes. Calculated pore-size metrics clearly illustrate the potential for temperature-mediated adsorption in ultramicroporous frameworks due to thermal fluctuations of the pore diameter near the value of the target guest kinetic diameter, though in [Cu3 (cdm)4 ] this is counteracted by a competing contraction of the pore with increasing temperature as a result of the anisotropic lattice response. PMID- 29450923 TI - Organic zinc and copper supplementation on antioxidant protective mechanism and their correlation with sperm functional characteristics in goats. AB - Trace minerals feeding had significant effects on sperm production and fertility with better absorption and proper utilization within the body for optimum reproductive function. Several studies have shown that more influenced trace elements in the diets of animals are copper (Cu) and zinc (Zn). Bucks showing deficiency of this mineral might affect the quality of semen production which in turn would affect the fertility. This experiment was thus designed to test the effects of organic Cu and Zn supplementation on antioxidants enzyme activities and sperm functional attributes in fresh semen of bucks. Forty bucks (n = 40, Aged 5 months) were assigned to ten groups of four animals in each group, supplemented (for a period of 8 months) with different levels of organic Zn: 20 mg (T2), 40 mg (T3) and 60 mg (T4), organic Cu: 12.5 mg (T5), 25 mg (T6), 37.5 mg (T7) and combined organic Zn and Cu: 20 + 12.5 mg (T8), 40 + 25 mg (T9), 60 + 37.5 mg (T10), respectively, per kg dry matter and no additional mineral diet (control; T1). One hundred and sixty semen samples were collected through electro ejaculator and analysed for sperm quantity, quality, acrosome intactness and plasma membrane integrity and correlated with the catalase, superoxide dismutase, glutathione peroxidase and glutathione reductase enzyme activities in seminal plasma. The results indicated organic Cu and zinc supplemented bucks produced more sperm cells, had higher sperm concentrations, maintained higher (p < .01) sperm livability, plasma membrane and acrosome integrities, more motility and velocity. The increased antioxidant enzyme activities, reduced oxidative stress and lowered lipid peroxidation were positively correlated (p < .05) with the sperm functional attributes. In conclusion, organic Cu and Zn supplement to male goats showed protective roles against oxidative damage and maintained better fresh semen characteristics.

By using Candida antartica Lipase B immobilized tubular reactor, narrowly dispersed poly(delta-valerolactone) with higher thiol fidelity is more efficiently prepared in contrast to the batch reactor. Moreover, the integrated enzyme packed tubular reactor system is established to perform the chain extension experiments. Thiol-terminated poly(delta-valerolactone)-block poly(epsilon-caprolactone) and poly(epsilon-caprolactone)-block-poly(delta valerolactone) are easily prepared by modulating the monomer introduction sequence.

AB - Two complementary thermoreversible ABC triblock copolymers containing either phenylboronic acids with low pKa values or galactosyl groups in the hydrophilic B blocks are synthesized by sequential reversible addition-fragmentation chain transfer polymerization and subsequent modification of the functional groups. Both ABC triblock copolymers undergo reversible sol-to-gel transitions upon temperature change and form physically cross-linked hydrogels under physiological conditions. Furthermore, the spontaneous adhesion of these thermoreversible hydrogels via the formation of boronic esters between the phenylboronic acid and galactosyl groups under physiological conditions is realized for the first time.

AB - Bovine granulosa cells (GC) vary in their morphological aspect during different stages of folliculogenesis. In this study, 10 morphologically normal bovine ovaries were collected to study the structural aspects of different stages of GC using intermediate filament protein antibodies including cytokeratin AE1/AE3 (AE1/AE3), vimentin, nectin-4 and desmin. Hormonal immunolocalization was assessed using the immunomarkers anti-Mullerian hormone (AMH) and inhibin alpha. In addition, tumour markers and proliferation markers using c-erbB-2 oncoprotein and proliferating cell nuclear antigen, respectively, were investigated. The immunolabelling of AE1/AE3 in GC was strongest in the early follicle stage and gradually decreased when reaching the Graafian follicle stage. Its immunolabelling increased again as the stage progressed from stage I to stage III. The immunolabelling of inhibin alpha was inversely proportional to that of AE1/AE3 in the developing ovarian follicles as their immunolabelling is opposite to each other during folliculogenesis. AMH was immunopositive in almost all GC stages in different intensities and percentages, except for some negative staining in the atretic IV follicles. The atretic IV follicle is a unique type of atretic follicle that shows Call-Exner body formation, which was mainly found in older cows in this study. The distinct patterns of immunoreactivity for various types of immunomarkers in the different GC stages will play an important role in diagnostic assistance of various follicle conditions, including cystic ovaries and GC tumours.

AB - Conjugated polyelectrolytes (CPEs) with pi-delocalized main backbones and ionic pendant groups are intensively studied as interfacial layers for efficient polymer-based optoelectronic devices (POEDs) because they facilitate facile control of charge injection/extraction barriers. Here, a simple and effective method of performing precise interfacial energy level adjustment is presented by employing CPEs with different thicknesses and various ion densities under electric poling to realize efficient charge injection/extraction of POEDs. The effects of the CPE ion densities and electric (positive or negative) poling on the energy level tuning process are investigated by measuring the open-circuit voltages and current densities of devices with the structure indium tin oxide/zinc oxide/CPE/organic active layer/molybdenum oxide/gold while changing the CPE film thickness. The performances of inverted polymer light-emitting diodes and inverted polymer solar cells are remarkably improved by precisely controlling the interfacial energy level matching using optimum CPE conditions.

AB - The lack of scalable and sustainable methods to prepare conjugated polymers belies their importance in many enabling technologies. Accessing high-performance poly(hetero)arene conjugated polymers by dehydration has remained an unsolved problem in synthetic chemistry and has historically required transitional-metal coupling reactions. Herein, we report a dehydration method that allows access to conjugated heterocyclic materials. By using the technique, we have prepared a series of small molecules and polymers. The reaction avoids using transition metals, proceeds at room temperature, the only required reactant is a simple base and water is the sole by-product. The dehydration reaction is technically simple and provides a sustainable and straightforward method to prepare conjugated heteroarene motifs. PMID- 29450930 TI - Neonatal meningococcal disease.

Polybenzoxazines with high sulfur contents are prepared using the SRTC reaction with benzoxazine compounds as the radical acceptors. The reactions between elemental sulfur and benzoxazine rings are analyzed with Fourier transform infrared (FTIR), 1 H NMR, and 13 C DEPT spectroscopies to elucidate the SRTC reaction mechanism. Moreover, the prepared polybenzoxazine-sulfur hybrid materials show attractive repairing properties based on the dynamic S-S linkages. An effective reaction mechanism and the prepared repairable sulfur-possessing polymeric materials are demonstrated. PMID- 29450933 TI - Face cooling reveals a relative inability to increase cardiac parasympathetic activation during passive heat stress. AB - NEW FINDINGS: What is the central question of this study? Does passive heat stress attenuate the increase in cardiac parasympathetic stimulation, vascular resistance and blood pressure evoked by face cooling? What is the main finding and its importance? Passive heat stress attenuates the capacity to increase cardiac parasympathetic activation and impairs the ability to increase vascular resistance during sympathoexcitation, which ultimately results in a relative inability to increase blood pressure. These findings cast doubt on the efficacy of face cooling at augmenting blood pressure during orthostasis while heat stressed. ABSTRACT: We tested the hypothesis that passive heat stress attenuates the increase in cardiac parasympathetic stimulation, vascular resistance and blood pressure evoked by face cooling. During normothermia and when intestinal temperature was elevated by 1.0 +/- 0.2 degrees C, 10 healthy young adults underwent 3 min of face cooling. Face cooling was accomplished by placing a 2.5 litre bag of ice water (0 +/- 0 degrees C) over the cheeks, eyes and forehead. Primary variables included forehead skin temperature, mean arterial pressure and systemic, forearm and cutaneous vascular resistances. Indices of heart rate variability in the time domain provided an index of cardiac parasympathetic activity. The magnitude of reduction in forehead skin temperature during face cooling was slightly greater during normothermia (-17.6 +/- 1.9 versus -16.3 +/- 3.0 degrees C, P = 0.03). Increases in heart rate variability evoked by face cooling were attenuated during heat stress. Changes in systemic, forearm and cutaneous vascular resistances during face cooling were virtually abolished during heat stress (P < 0.01). However, when forearm and vascular data were reported as conductance, differences between normothermia and heat stress were not apparent (P >= 0.62). Nevertheless, the increase in mean arterial pressure was attenuated during heat stress with face cooling (at 3 min: 2 +/- 7 mmHg) compared with normothermia (at 3 min: 19 +/- 7 mmHg, P < 0.01). These data indicate that passive heat stress attenuates face cooling-evoked increases in cardiac parasympathetic activation, vascular resistance and blood pressure. However, they also indicate that changes in indices of vascular resistance do not always reflect equivalent changes in conductance.

AB - Cardiorespiratory fluctuations such as changes in heart rate or respiration volume influence the temporal dynamics of cerebral blood flow (CBF) measurements during arterial spin labeling (ASL) fMRI. This "physiological noise" can confound estimates of resting state network activity, and it may lower the signal-to-noise ratio of ASL during task-related experiments. In this study we examined several methods for minimizing the contributions of both synchronized and non synchronized physiological noise in ASL measures of CBF, by combining the RETROICOR approach with different linear deconvolution models. We evaluated the amount of variance in CBF that could be explained by each method during physiological rest, in both resting state and task performance conditions. To further demonstrate the feasibility of this approach, we induced low-frequency cardiorespiratory deviations via peripheral adrenergic stimulation with isoproterenol, and determined how these fluctuations influenced CBF, before and after applying noise correction. By suppressing physiological noise, we observed substantial improvements in the signal-to-noise ratio at the individual and group activation levels. Our results suggest that variations in cardiac and respiratory parameters can account for a large proportion of the variance in resting and task based CBF, and indicate that regressing out these non-neuronal signal variations improves the intrinsically low signal-to-noise ratio of ASL. This approach may help to better identify and control physiologically driven activations in ASL resting state and task-based analyses.

AB - Since their discovery in 1993, interest in various aspects of cyclic peptides (CPs) has expanded rapidly. Of particular note is their potential to form artificial ion channels in lipid membranes, an attractive characteristic in supramolecular chemistry and biological research. The design and synthesis of cyclic peptide-polymer conjugates (CPPCs) that can self-assemble within lipid bilayers into nanotubes, mimicking naturally occurring membrane channels and pores, has been reported. However, methods that allow direct detection of the transport process with high levels of certainty are still lacking. This work focuses on the development of a simple but reliable approach to verify and quantify proton transport across a bilayer membrane. Giant unilamellar vesicles (GUVs) are created via the electroformation method and CPPCs are incorporated in GUV membranes at varying concentrations (0-10%). Confocal fluorescence microscopy is used to demonstrate full inclusion of fluorescein-labeled CPPCs in the GUV membranes. The pH-sensitive dye carboxyfluorescein is encapsulated within the water pool of the GUVs and used as an indicator of proton transport. This assay is versatile and can be exploited on other existing proton transporter systems, providing a consistent tool to compare their performances. It should also aid the development of novel antineoplastics and drug delivery systems.

AB - Adolescents' exposure to community violence is a significant public health issue in urban settings and has been associated with poorer cognitive performance and increased risk for psychiatric illnesses, including PTSD. However, no study to date has investigated the neural correlates of community violence exposure in adolescents. Sixty-five healthy adolescents (age = 14-18 years; 36 females, 29 males) from moderate- to high-crime neighborhoods in Los Angeles reported their violence exposure, parents' education level, and free/reduced school lunch status (socio-economic status, SES), and underwent structural neuroimaging and intelligence testing. Violence exposure negatively correlated with measures of SES, IQ, and gray matter volume. Above and beyond the effect of SES, violence exposure negatively correlated with IQ and with gray matter volume in the left inferior frontal gyrus and anterior cingulate cortex, regions involved in high level cognitive functions and autonomic modulation, and previously shown to be reduced in PTSD and combat-exposed military populations. The current results provide first evidence that frontal brain regions involved in cognition and affect appear to be selectively affected by exposure to community violence, even in healthy nondelinquent adolescents who are not the direct victims or perpetrators of violence. PMID- 29450936 TI - Correcting for missing and irregular data in home-range estimation. AB - Home-range estimation is an important application of animal tracking data that is frequently complicated by autocorrelation, sampling irregularity, and small effective sample sizes. We introduce a novel, optimal weighting method that accounts for temporal sampling bias in autocorrelated tracking data. This method corrects for irregular and missing data, such that oversampled times are downweighted and undersampled times are upweighted to minimize error in the home range estimate. We also introduce computationally efficient algorithms that make this method feasible with large data sets. Generally speaking, there are three situations where weight optimization improves the accuracy of home-range estimates: with marine data, where the sampling schedule is highly irregular, with duty cycled data, where the sampling schedule changes during the observation period, and when a small number of home-range crossings are observed, making the beginning and end times more independent and informative than the intermediate times. Using both simulated data and empirical examples including reef manta ray, Mongolian gazelle, and African buffalo, optimal weighting is shown to reduce the error and increase the spatial resolution of home-range estimates. With a conveniently packaged and computationally efficient software implementation, this method broadens the array of data sets with which accurate space-use assessments can be made. PMID- 29450937 TI - Adaptation of mineral trioxide aggregate to dentine walls compared with other root-end filling materials: A systematic review. AB - This systematic review analysed the literature comparing marginal adaptation of mineral trioxide aggregate (MTA) with other filling materials in root-end cavities. The PubMed, Ovid, Web of Science, SCOPUS, and Cochrane library databases were searched using appropriate keywords related to root-end filling materials and adaptation. Of 38 articles assessed, 20 met the inclusion criteria. No in vivo study was identified. In 10 studies, MTA gave the best marginal adaptation results, but no significant differences were found between MTA and any of the tested filling materials in seven studies. There was great variability in the study designs including analysed surface, unit of gap measurement and magnification amount during analysis. On the basis of available evidence, MTA presented good marginal adaptation to dentine walls. This review identified the need for the development of standardised methods to evaluate the adaptation property of root-end filling materials in ex vivo studies as well as in clinical studies evaluating outcome. PMID- 29450938 TI - Hot Off the Press: Peripheral Intravenous Cannula Insertion and Use in the Emergency Department. AB - This is a prospective before-after study comparing peripheral intravenous cannulation (PIVC) placement and usage rates following a 10-week-long multimodal intervention provided to medical and nursing staff working in a tertiary emergency department (ED). The intervention focused on improving appropriate use of PIVCs in an emergency setting by emphasizing to clinicians that a PIVC should only be placed if it was believed there was more than an 80% chance that it would be used. Patients were eligible for the study if they presented to the ED and were >18 years of age. Patients were excluded from the study if they were triage category 1, already had a PIVC placed in an ambulance, or were transferred from another hospital. Among the 4,172 patients included in the analysis, there was a 9.8% reduction in the number of PIVCs inserted (95% confidence interval [CI] = 6.8-12.87) and a 12% increase in PIVC usage (95% CI = 8.7%-17.0%) in the postintervention cohort. PMID- 29450939 TI - Unexplained infertility patients present the mostly impaired levels of progesterone receptors: Prospective observational study. AB - PROBLEM: Tauo assess the endometrial expression of progesterone receptors in various subgroups of infertile women during implantation window. MUETHODS: A prospective observational study was performed during March 2013-February 2017. Infertile women were categorized to those with tubal factor, ovarian failure, endometriosis or unexplained infertility. Endometrial biopsy was obtained on 7th 8th postovulatory day. Total progesterone receptors' PR(A + B) and type-B receptors' (PR-B) expression were compared between all categories of infertile and fruitful controls. RESULTS: There were overall 30 patients with tubal factor infertility (group 1), 30 with ovarian failure (group 2), 20 with endometriosis (group 3) and 20 with unexplained infertility (group 4). The control group consisted of 30 fertile patients. Patients with unexplained infertility presented the lowest levels of epithelial endometrial expression both regarding PR(A + B) and PR-B receptors. PgR(A + B) h-score in luminal epithelial cells was 106.4 +/- 14.7 for cases with unexplained infertility vs 219.7 +/- 15.8 for controls (P < .001). Similarly, PgR(A + B) h-score in glandular epithelial cells was 109.7 +/- 13.9 vs 220.1 +/- 17.2 (P < .001). Relative remarks were made for type-B progesterone receptors. CONCLUSION: Epsilonndometrial expression of progesterone receptors is impaired in women with unexplained infertility. Therapeutic strategies targeting on improving progesterone receptors' expression may significantly affect final reproductive outcome. PMID- 29450940 TI - Statistical inference in brain graphs using threshold-free network-based statistics. AB - The description of brain networks as graphs where nodes represent different brain regions and edges represent a measure of connectivity between a pair of nodes is an increasingly used approach in neuroimaging research. The development of powerful methods for edge-wise group-level statistical inference in brain graphs while controlling for multiple-testing associated false-positive rates, however, remains a difficult task. In this study, we use simulated data to assess the properties of threshold-free network-based statistics (TFNBS). The TFNBS combines threshold-free cluster enhancement, a method commonly used in voxel-wise statistical inference, and network-based statistic (NBS), which is frequently used for statistical analysis of brain graphs. Unlike the NBS, TFNBS generates edge-wise significance values and does not require the a priori definition of a hard cluster-defining threshold. Other test parameters, nonetheless, need to be set. We show that it is possible to find parameters that make TFNBS sensitive to strong and topologically clustered effects, while appropriately controlling false positive rates. Our results show that the TFNBS is an adequate technique for the statistical assessment of brain graphs. PMID- 29450941 TI - Hematogenous Dissemination of Mesenchymal Stem Cells from Endometriosis. AB - Endometriosis is ectopic growth of endometrial tissue traditionally thought to arise through retrograde menstruation. We aimed to determine if cells derived from endometriosis could enter vascular circulation and lead to hematogenous dissemination. Experimental endometriosis was established by transplanting endometrial tissue from DsRed+ mice into the peritoneal cavity of DsRed- mice. Using flow cytometry, we identified DsRed+ cells in blood of animals with endometriosis. The circulating donor cells expressed CXCR4 and mesenchymal stem cell (MSC) biomarkers, but not hematopoietic stem cell markers. Nearly all the circulating endometrial stem cells originated from endometriosis rather than from the uterus. Cells expressing DsRed, CXCR4, and MSCs markers were identified in the peritoneal wall and surrounding vessels of recipient mice, contributing to both endometriosis and angiogenesis. Cells originating in endometriosis lesions migrated and implanted in lung tissue and displayed makers of differentiation, indicating retained multipotency. In vitro these cells demonstrated multipotency and were able to differentiate into adipogenic, osteogenic, and chondrogenic lineages. Endometriosis lesions also expressed high levels of CXCL12, the CXCR4 receptor ligand. Serum CXCL12 levels were greater than in sham control mice. In humans with endometriosis, serum CXCL12 levels were significantly higher than controls, suggesting that the CXCL12/CXCR4 axis is operational in women with spontaneous endometriosis as well. Stem cells, rather than differentiated cells from endometriosis, enter the circulation in response to CXCL12. We identify an endometriosis-derived stem cell population, a potential mechanism of dissemination of this disease and a potential target for treatment of endometriosis. Stem Cells 2018;36:881-890. PMID- 29450942 TI - Multivariate analysis of cytokine profiles in pregnancy complications. AB - PROBLEM: The immunoregulation to tolerate the semiallogeneic fetus during pregnancy includes a harmonious dynamic balance between anti- and pro inflammatory cytokines. Several earlier studies reported significantly different levels and/or ratios of several cytokines in complicated pregnancy as compared to normal pregnancy. However, as cytokines operate in networks with potentially complex interactions, it is also interesting to compare groups with multi cytokine data sets, with multivariate analysis. Such analysis will further examine how great the differences are, and which cytokines are more different than others. METHODS: Various multivariate statistical tools, such as Cramer test, classification and regression trees, partial least squares regression figures, 2-dimensional Kolmogorov-Smirmov test, principal component analysis and gap statistic, were used to compare cytokine data of normal vs anomalous groups of different pregnancy complications. RESULTS: Multivariate analysis assisted in examining if the groups were different, how strongly they differed, in what ways they differed and further reported evidence for subgroups in 1 group (pregnancy induced hypertension), possibly indicating multiple causes for the complication. CONCLUSION: This work contributes to a better understanding of cytokines interaction and may have important implications on targeting cytokine balance modulation or design of future medications or interventions that best direct management or prevention from an immunological approach. PMID- 29450943 TI - Cortical projections to the superior colliculus in grey squirrels (Sciurus carolinensis). AB - The superior colliculus is an important midbrain structure involved with integrating information from varying sensory modalities and sending motor signals to produce orienting movements towards environmental stimuli. Because of this role, the superior colliculus receives a multitude of sensory inputs from a wide variety of subcortical and cortical structures. Proportionately, the superior colliculus of grey squirrels is among the largest in size of all studied mammals, suggesting the importance of this structure in the behavioural characteristics of grey squirrels. Yet, our understanding of the connections of the superior colliculus in grey squirrels is lacking, especially with respect to possible cortical influences. In this study, we placed anatomical tracer injections within the medial aspect of the superior colliculus of five grey squirrels (Sciurus carolinensis) and analysed the areal distribution of corticotectal projecting cells in flattened cortex. V1 projections to the superior colliculus were studied in two additional animals. Our results indicate that the superior colliculus receives cortical projections from visual, higher order somatosensory, and higher order auditory regions, as well as limbic, retrosplenial and anterior cingulate cortex. Few, if any, corticotectal projections originate from primary motor, primary somatosensory or parietal cortical regions. This distribution of inputs is similar to the distribution of inputs described in other rodents such as rats and mice, yet the lack of inputs from primary somatosensory and motor cortex is features of corticotectal inputs more similar to those observed in tree shrews and primates, possibly reflecting a behavioural shift from somatosensory (vibrissae) to visual navigation. PMID- 29450945 TI - Clinical application of 3D technology for tooth autotransplantation: A case report. AB - This report presents two cases of tooth autotransplantation using cone-beam computed tomography (CBCT), the three-dimensional (3D) simulation dental planning software and a computer-aided rapid prototyping (CARP) model. Two hopeless teeth of adult patients were replaced as their third molar teeth. Before deciding the autotransplantation, diagnostic CBCT images were acquired and imported to SimPlant software. The SimPlant dental program was used for surgical simulation prior to autotransplantation, which created 3D images of the available donor teeth and recipient site tooth and superimposed the images to display their morphological similarity. Efficient modification of the recipient socket was designed preoperatively. The CARP model of the donor tooth was prepared as a substitute for the donor tooth that would be fit into the new recipient socket during bone preparation. Autotransplantation was favourably performed in 5-6 min. Transplanted teeth healed up without clinical abnormality. The postoperative follow-up time was up to 6 years. PMID- 29450944 TI - NRF2 addiction in cancer cells. AB - The Kelch-like ECH-associated protein 1/nuclear factor erythroid-derived 2-like 2 (KEAP1-NRF2) system is a pivotal defense mechanism against oxidative and electrophilic stress. Although transient NRF2 activation in response to stress is beneficial for health, persistent NRF2 activation in cancer cells has deleterious effects on cancer-bearing hosts by conferring therapeutic resistance and aggressive tumorigenic activity on cancer cells. Because NRF2 increases the antioxidant and detoxification capability of cancer cells, persistently high levels of NRF2 activity enhance therapeutic resistance of cancer cells. NRF2 also drives metabolic reprogramming to establish cellular metabolic processes that are advantageous for cell proliferation in cooperation with other oncogenic pathways. As a result of these advantages, cancer cells with persistent activation of NRF2 often develop "NRF2 addiction" and show malignant phenotypes leading to poor prognoses in cancer patients. Inhibition of NRF2 is a promising therapeutic approach for NRF2-addicted cancers and NRF2 inhibitors are being actively developed. However, giving systemic NRF2 inhibitors might have undesirable effects on cancer-bearing hosts, considering the central roles of NRF2 in cytoprotection. To avoid these side-effects, new therapeutic targets besides NRF2 for NRF2-addicted cancers have been actively explored. This review introduces recent studies describing the development and characterization of NRF2-addicted cancers, as well as their potential therapeutic targets. Expected advances in diagnostic and therapeutic interventions for NRF2-addicted cancers are also discussed. PMID- 29450947 TI - Effects of climate on soil phosphorus cycle and availability in natural terrestrial ecosystems. AB - Climate is predicted to change over the 21st century. However, little is known about how climate change can affect soil phosphorus (P) cycle and availability in global terrestrial ecosystems, where P is a key limiting nutrient. With a global database of Hedley P fractions and key-associated physiochemical properties of 760 (seminatural) natural soils compiled from 96 published studies, this study evaluated how climate pattern affected soil P cycle and availability in global terrestrial ecosystems. Overall, soil available P, indexed by Hedley labile inorganic P fraction, significantly decreased with increasing mean annual temperature (MAT) and precipitation (MAP). Hypothesis-oriented path model analysis suggests that MAT negatively affected soil available P mainly by decreasing soil organic P and primary mineral P and increasing soil sand content. MAP negatively affected soil available P both directly and indirectly through decreasing soil primary mineral P; however, these negative effects were offset by the positive effects of MAP on soil organic P and fine soil particles, resulting in a relatively minor total MAP effect on soil available P. As aridity degree was mainly determined by MAP, aridity also had a relatively minor total effect on soil available P. These global patterns generally hold true irrespective of soil depth (<=10 cm or >10 cm) or site aridity index (<=1.0 or >1.0), and were also true for the low-sand (<=50%) soils. In contrast, available P of the high-sand (>50%) soils was positively affected by MAT and aridity and negatively affected by MAP. Our results suggest that temperature and precipitation have contrasting effects on soil P availability and can interact with soil particle size to control soil P availability. PMID- 29450946 TI - Downregulation of leucine-rich repeats and immunoglobulin-like domains 1 by microRNA-20a modulates gastric cancer multidrug resistance. AB - Multidrug resistance (MDR) significantly restricts the clinical efficacy of gastric cancer (GC) chemotherapy, and it is critical to search novel targets to predict and overcome MDR. Leucine-rich repeats and immunoglobulin-like domains 1 (LRIG1) has been proved to be correlated with drug resistance in several cancers. The present study revealed that LRIG1 was overexpressed in chemosensitive GC tissues and decreased expression of LRIG1 predicted poor survival in GC patients. We observed that upregulation of LRIG1 enhanced chemosensitivity in GC cells. Interestingly, miR-20a, which was overexpressed in GC MDR cell lines and tissues, was identified to regulate LRIG1 expression by directly targeting its 3' untranslated region. We also found that inhibition of miR-20a suppressed GC MDR, and upregulation showed opposite effects. Moreover, we demonstrated that the miR 20a/LRIG1 axis regulated GC cell MDR through epidermal growth factor receptor (EGFR)-mediated PI3K/AKT and MAPK/ERK signaling pathways. Finally, LRIG1 expression in human GC tissues is inversely correlated with miR-20a and EGFR. Taken together, the newly identified miR-20a/LRIG1/EGFR link provides insight into the MDR process of GC, and targeting this axis represents a novel potential therapeutic strategy to block GC chemoresistance.

AB - The spatial deployment of lateral roots determines the ability of a plant to interact with the surrounding environment for nutrition and anchorage. This paper shows that besides the pericycle, the vascular cambium becomes active in Arabidopsis thaliana taproot at a later stage of development and is also able to form new lateral roots. To demonstrate the above, we implemented a two-step approach in which the first step leads to development of a secondary structure in A. thaliana taproot, and the second applies a mechanical stress on the vascular cambium to initiate formation of a new lateral root primordium. GUS staining showed PRE3, DR5 and WOX11 signals in the cambial zone of the root during new lateral root formation. An advanced level of wood formation, characterized by the presence of medullar rays, was achieved. Preliminary investigations suggest the involvement of auxin and two transcription factors (PRE3/ATBS1/bHLH135/TMO7 and WOX11) in the transition of some vascular cambium initials from a role as producers of xylem/phloem mother cells to founder cells of a new lateral root primordium.

AB - Information on metallophytes during reclamation of land contaminated with heavy metals is sparse. We investigated the response of D. carthusianorum calamine ecotype to Pb and Cd stress. We focused on in vitro selection of tolerant plant material for direct use in chemically degraded areas. Shoot cultures were treated with various concentrations of Pb or Cd ions. Plantlet status was estimated as micropropagation efficiency, growth tolerance index (GTI) and through physiological analysis. Moreover, determination of plant Pb, Cd and other elements was performed. The application of Pb(NO3 )2 resulted in stronger growth inhibition than application of CdCl2 . In the presence of Pb ions, a reduction was observed of both, the micropropagation coefficient to 1.1-1.8 and the GTI to 48%. In contrast, Cd ions had a positive influence on tested cultures, expressed as an increase of GTI up to 243% on medium enriched with 1.0 MUm CdCl2 . Moreover, photosynthetic pigment content in shoots cultivated on media with CdCl2 was higher than in control treatment. The adaptation to Cd was associated with decreased accumulation of phenols in the order: 0.0 MUm > 1.0 MUm > 3.0 MUm > 5.5 MUm CdCl2 . It seems that high tolerance to Cd is related to K uptake, which is involved in antioxidant defence. This work presents an innovative approach to the impact of Cd ions on plant growth and suggests a potential biological role of this metal in species from metalliferous areas. PMID- 29450952 TI - Two Stereoinduction Events in One C-H Activation Step: A Route towards Terphenyl Ligands with Two Atropisomeric Axes. AB - Herein we disclose the synthesis of original chiral scaffolds-ortho-orientated terphenyls presenting two atropisomeric Ar-Ar axes. These unusual structures were built up by using the C-H activation approach, and remarkably, both chiral axes were controlled with excellent stereoselectivity in a single transformation. During the reaction, not only does atroposelective functionalization of a biaryl precursor occur to establish one stereogenic axis, but an unprecedented atropo stereoselective C-H arylation also takes place to generate the second stereogenic element. These enantiomerically pure ortho-terphenyls show an original tridimensional structure and thus constitute a unique foundation for building up a library of enantiomerically pure bidentate ligands, such as the new ligands S/N Biax and diphosphine BiaxPhos. PMID- 29450953 TI - Factors influencing seedling emergence of three global invaders in greenhouses representing major eco-regions of the world. AB - Successful germination and seedling emergence in new environments are crucial first steps in the life history of global plant invaders and thus play a key role in processes of range expansion. We examined the germination and seedling emergence success of three global plant invaders - Lupinus polyphyllus, Senecio inaequidens and Verbascum thapsus - in greenhouses and climate chambers under climate regimes corresponding to seven eco-regions. Seed materials were collected from one non-native population for L. polyphyllus and S. inaequidens, and from 12 populations for V. thapsus (six natives and six non-natives). Experimental climates had significant effects on species responses. No species germinated in the dry (humidity <= 50%) and cool (<= 5 degrees C) experimental climates. But all species germinated and emerged in two moderately cool (12-19 degrees C) and in three warm (24-27 degrees C) experimental climates. In general, V. thapsus showed higher fitness than S. inaequidens and L. polyphyllus. The climate of the seed source region influenced responses of native and non-native populations of V. thapsus. Non-native populations of V. thapsus, originating from the warmer seed source, showed higher performance in warm experimental climates and lower performance in moderately cool experimental climates compared to native populations. Responses of V. thapsus populations were also related to precipitation of the seed source region in moderately dry experimental climates. The warm, semi-arid and humid experimental climates are suitable for the crucial first steps of invasion success for L. polyphyllus, S. inaequidens and V. thapsus. The species adaptation to its source region modified the responses of our studied plants under different experimental climates representing major eco regions of the world. PMID- 29450954 TI - Initiation and long-term use of benzodiazepines and Z-drugs in bipolar disorder. AB - OBJECTIVES: Increasing evidence points to the harmful effects of long-term benzodiazepine treatment. Our objective was to study the incidence of, and predictors for, long-term use of benzodiazepines and Z-drugs in bipolar disorder. METHODS: We conducted a population-based cohort study, using data from Swedish national registers. Swedish residents aged 18-75 years with a recorded diagnosis of bipolar disorder or mania between July 2006 and December 2012, and no history of benzodiazepine/Z-drug use in the past year, were included. Patients were followed for 1 year with regard to prescription fills of benzodiazepines/Z-drugs. Initiators were followed for another year during which continuous use for >6 months was defined as "long-term". Patient and prescription characteristics were investigated as potential predictors for long-term use in multivariate logistic regression models. RESULTS: Out of the 21 883 patients included, 29% started benzodiazepine/Z-drug treatment, of whom one in five became long-term users. Patients who were prescribed clonazepam or alprazolam had high odds for subsequent long-term use (adjusted odds ratios [aORs] 3.78 [95% confidence interval (CI) 2.24-6.38] and 2.03 [95% CI 1.30-3.18], respectively), compared to those prescribed diazepam. Polytherapy with benzodiazepines/Z-drugs also predicted long-term use (aOR 2.46, 95% CI 1.79-3.38), as did age >=60 years (aOR 1.93, 95% CI 1.46-2.53, compared to age <30 years), and concomitant treatment with psychostimulants (aOR 1.78, 95% CI 1.33-2.39). CONCLUSIONS: The incidence of subsequent long-term use among bipolar benzodiazepine initiators is high. Patients on clonazepam, alprazolam or benzodiazepine/Z-drug polytherapy have the highest risk of becoming long-term users, suggesting that these treatments should be used restrictively.

For R=tBu, the organolithium derivative (eta5 -Cp)Fe{eta5 -C5 H3 -1-(ArLiNCHR)-2-(CH2 NMe2 )} (2) was isolated. Compound 2 reacts with GeCl2 ?dioxane and SnCl2 to give the metallylene amide chlorides (eta5 -Cp)Fe{eta5 -C5 H3 -1-(ArMNCHtBu)-2-(CH2 NMe2 )} 6 (M=GeCl) and 7 (M=SnCl), respectively, which each contain three stereogenic centers.

Treatment of 3 with tert-butyllithium at room temperature causes an unprecedented carbon-carbon bond cleavage whereas under kinetic control, lithiation at the Cp-3 position takes place, which leads to the isolation of (eta5 -Cp)Fe{eta5 -C5 H3 -1-(ArHNCHtBu)-2-(CH2 NMe2 )-3-SiMe3 } (10).

AB - The multistate redox-active/multi-interactive ligand 5,5',8,8'-tetra(4-pyridyl) 2,2'-(1,4-phenylene)bis-1H-perimidine (H2 TPP) was designed and synthesized. H2 TPP undergoes four one-electron oxidation steps, and was used for the preparation of a multistate redox-active coordination network in a solid-liquid interface reaction using molten Cd2+ salts. The multiple redox states of H2 TPP were confirmed spectroscopically by stepwise four-electron oxidation. Spectroscopic analysis indicated that the mixed-valence states of the ligand are class II on the UV/Vis/NIR timescale and borderline class II/class III on the ESR timescale.

PMID- 29450958 TI - Use of physician-recommended non-pharmacological strategies for hypertension control among hypertensive patients. AB - This study aims to evaluate the 4 non-pharmacological strategies adopted by patients for hypertension control and patient characteristics that affect the choice of strategies. Four thousand hypertensive patients aged >=18 years were selected from the National Health and Nutrition Examination Survey. Odds ratios of the choice of strategies were analyzed using weighted logistic models. Clinical recommendations of non-pharmacological strategies for hypertension control were relatively low. More exercise was the least frequent strategy used for hypertension control. More patients reported using >=3 strategies than using <=2 strategies (79.1% vs 20.9%, P < .0001). Non-Hispanic blacks were more likely to use each individual strategy and to use >=3 strategies simultaneously. Patients with obesity and diabetes were less likely to attempt weight control or more exercise, but more likely to use >=3 strategies than peers. Educational programs should be developed to enhance physician's advice for lifestyle modifications and to increase patient's acceptance of physical activity.

AB - Whether elevated uric acid (UA) is an independent risk factor for chronic kidney disease (CKD) is not well established. The authors evaluated the relationship of UA with rapid kidney function decline (RKFD) and incident CKD among 3702 African Americans (AAs) in the Jackson Heart Study with serum UA levels measured at baseline exam (2000-2004). RKFD was defined as >= 30% eGFR loss and incident CKD as development of eGFR < 60 mL/min/1.73 m2 with a >= 25% decline in eGFR between baseline and exam 3 (2009-2013). RKFD and CKD were found in 11.4% and 7.5% of the participants, respectively. In a fully adjusted model, the odds of RKFD (OR, 1.8; 95% CI, 1.25-2.49) and incident CKD (OR, 2.00; 95% CI, 1.31-3.06) were significantly higher among participants in the top UA quartile vs bottom quartile. In the JHS, elevated UA was significantly associated with RKFD and incident CKD. PMID- 29450960 TI - Effect of flower orientation on the male and female traits of Myrtillocactus geometrizans (Cactaceae). AB - Intra-individual variation in the production and size of reproductive traits has been documented in columnar cacti, being higher in equator-facing flowers. Such variation is attributed to the high amount of PAR intercepted by stems oriented towards the equator. Most studies focused on this phenomenon have documented the existence of intra-individual variation on traits associated with the female function; however, its impact on traits associated with the male function has been neglected. We tested the hypothesis that equator-facing flowers of Myrtillocactus geometrizans exhibit higher values on traits associated with both male and female functions than flowers facing against it. Number and size of anthers and ovaries, pollen:ovule ratio and number and quality of pollen grains (diameter, germinability, viability and pollen tube length) were estimated from reproductive structures facing north and south, and compared with t-tests between orientations. Number of anthers per flower, number of pollen grains per anther and per floral bud; pollen size, viability and germinability; pollen tube length; ovary length and pollen:ovule ratio were significantly higher in reproductive structures oriented towards the south (i.e. equator). These findings suggest that intra-individual variation in floral traits of M. geometrizans might be associated with different availability of resources in branches with contrasting orientation. Our results provide new evidence of the existence of a response to an orientation-dependent extrinsic gradient. To our knowledge, this is the first study documenting the existence of intra-individual variation on pollen quality and P:O ratio in Cactaceae species.

PMID- 29450961 TI - Volumetric-based image guidance is superior to marker-based alignments for stereotactic body radiotherapy of prostate cancer. AB - PURPOSES: The aim of this study was to evaluate a dual marker-based and soft tissue based image guidance for inter-fractional corrections in stereotactic body radiotherapy (SBRT) of prostate cancer. METHODS/MATERIALS: We reviewed 18 patients treated with SBRT for prostate cancer. An endorectal balloon was inserted at simulation and each treatment. Planning margins were 3 mm/0 mm posteriorly. Prior to each treatment, a dual image guidance protocol was applied to align three makers using stereoscopic x ray images and then to the soft tissue using kilo-voltage cone beam CT (kV-CBCT). After treatment, prostate (CTV), rectal wall, and bladder were delineated on each kV-CBCT, and delivered dose was recalculated. Dosimetric endpoints were analyzed, including V36.25 Gy for prostate, and D0.03 cc for bladder and rectal wall. RESULTS: Following initial marker alignment, additional translational shifts were applied to 22 of 84 fractions after kV-CBCT. Among the 22 fractions, ten fractions exceeded 3 mm shifts in any direction, including one in the left-right direction, four in the superior-inferior direction, and five in the anterior-posterior direction. With and without the additional kV-CBCT shifts, the average V36.25 Gy of the prostate for the 22 fractions was 97.6 +/- 2.6% with the kV x ray image alone, and was 98.1 +/- 2.4% after applying the additional kV-CBCT shifts. The improvement was borderline statistical significance using Wilcoxon signed-rank test (P = 0.007). D0.03 cc was 45.8 +/- 6.3 Gy vs. 45.1 +/- 4.9 Gy for the rectal wall; and 49.5 +/ 8.6 Gy vs. 49.3 +/- 7.9 Gy for the bladder before and after applying kV-CBCT shifts. CONCLUSIONS: Marker-based alignment alone is not sufficient. Additional adjustments are needed for some patients based kV-CBCT. PMID- 29450963 TI - Multicellular Tumor Spheroids (MCTS) as a 3D In Vitro Evaluation Tool of Nanoparticles. AB - Multicellular tumor spheroid models (MCTS) are often coined as 3D in vitro models that can mimic the microenvironment of tissues. MCTS have gained increasing interest in the nano-biotechnology field as they can provide easily accessible information on the performance of nanoparticles without using animal models. Considering that many countries have put restrictions on animals testing, which will only tighten in the future as seen by the recent developments in the Netherlands, 3D models will become an even more valuable tool. Here, an overview on MCTS is provided, focusing on their use in cancer research as most nanoparticles are tested in MCTS for treatment of primary tumors. Thereafter, various types of nanoparticles-from self-assembled block copolymers to inorganic nanoparticles, are discussed. A range of physicochemical parameters including the size, shape, surface chemistry, ligands attachment, stability, and stiffness are found to influence nanoparticles in MCTS. Some of these studies are complemented by animal studies confirming that lessons from MCTS can in part predict the behaviour in vivo. In summary, MCTS are suitable models to gain additional information on nanoparticles. While not being able to replace in vivo studies, they can bridge the gap between traditional 2D in vitro studies and in vivo models. PMID- 29450964 TI - Imparting Designer Biorecognition Functionality to Metal-Organic Frameworks by a DNA-Mediated Surface Engineering Strategy. AB - Surface functionality is an essential component for processing and application of metal-organic frameworks (MOFs). A simple and cost-effective strategy for DNA mediated surface engineering of zirconium-based nanoscale MOFs (NMOFs) is presented, capable of endowing them with specific molecular recognition properties and thus expanding their potential for applications in nanotechnology and biotechnology. It is shown that efficient immobilization of functional DNA on NMOFs can be achieved via surface coordination chemistry. With this strategy, it is demonstrated that such porphyrin-based NMOFs can be modified with a DNA aptamer for targeting specific cancer cells. Furthermore, the DNA-NMOFs can facilitate the delivery of therapeutic DNA (e.g., CpG) into cells for efficient recognition of endosomal Toll-like receptor 9 and subsequent enhanced immunostimulatory activity in vitro and in vivo. No apparent toxicity is observed with systemic delivery of the DNA-NMOFs in vivo. Overall, these results suggest that the strategy allows for surface functionalization of MOFs with different functional DNAs, extending the use of these materials to diverse applications in biosensor, bioimaging, and nanomedicine. PMID- 29450965 TI - Risk of early-onset breast cancer among women exposed to thoracic computed tomography in pregnancy or early postpartum. AB - : Essentials Tests for pulmonary embolism expose women to low-dose radiation. 5859 pregnancies had a thoracic computed tomography (T-CT) vs. 1.3 million who did not. The adjusted hazard ratio for breast cancer was 1.17 (95% confidence interval 0.80-1.70). The long-term risk of breast cancer among women who had a T CT remains unknown. SUMMARY: Background The risk of breast cancer may be higher with direct exposure to ionizing radiation from thoracic computed tomography (CT) during pregnancy or the postpartum. We evaluated the short-term risk of maternal breast cancer after exposure to thoracic CT during these periods. Methods We completed a retrospective population-based cohort study of all deliveries between 1995 and 2014 using universal healthcare databases in the province of Ontario, Canada. The main exposure was thoracic CT in pregnancy or <= 42 days postpartum. The passive exposure was ventilation-perfusion scintigraphy (VQ) scan in pregnancy or <= 42 days postpartum. Each was compared to pregnancies unexposed to thoracic CT or VQ scan. The primary study outcome was newly diagnosed breast cancer starting 366 days post-index delivery date. Results A total of 5859 pregnancies were exposed to thoracic CT, 4075 to VQ scan and 1 292 059 to neither. Starting from 1 year after the index delivery, the median duration of follow-up was 5.9, 7.3 and 11.1 years, respectively. A total of 10 129 women were diagnosed with breast cancer, of whom 9039 (89.2%) were aged <= 50 years. There were 27 new cases of breast cancer (7.1 per 10 000 person-years) following thoracic CT vs. 10 080 (7.0 per 10 000 person-years) among the unexposed, an adjusted hazard ratio (HR) of 1.17 (95% confidence interval [CI], 0.80-1.70). Following VQ scan exposure, the incidence rate of breast cancer was 7.0 per 10 000 person-years, an adjusted HR of 1.23 (95% CI 0.81-1.87), compared with the unexposed cohort. Conclusion Exposure to thoracic CT during pregnancy or the postpartum was not associated with an increased short-term risk of maternal breast cancer. The long-term risk should be studied. PMID- 29450966 TI - Highly Uniform Resistive Switching Properties of Solution-Processed Silver Embedded Gelatin Thin Film. AB - The silver-embedded gelatin (AgG) thin film produced by the solution method of metal salts dissolved in gelatin is presented. Its simple fabrication method ensures the uniform distribution of Ag dots. Memory devices based on AgG exhibit good device performance, such as the ON/OFF ratio in excess of 105 and the coefficient of variation in less of 50%. To further investigate the position of filament formation and the role of each element, current sensing atomic force microscopy (CSAFM) analysis as well as elemental line profiles across the two different conditions in the LRS and HRS are analyzed. The conductive and nonconductive regions in the current map of the CSAFM image show that the conductive filaments occur in the AgG layer around Ag dots. The migration of oxygen ions and the redox reaction of carbon are demonstrated to be the driving mechanism for the resistive switching of AgG memory devices. The results show that dissolving metal salts in gelatin is an effective way to achieve high performance organic-electronic applications. PMID- 29450967 TI - Carotid atherosclerosis and the association between nocturnal blood pressure dipping and cardiovascular events. AB - The impact of a nondipping blood pressure (BP) pattern, defined as (awake systolic BP - sleep systolic BP)/awake systolic BP < 0.1, on cardiovascular events in populations with different degrees of carotid atherosclerosis is uncertain. The authors hypothesized that a nondipping BP pattern would show differential predictive power for cardiovascular events, including total cardiovascular death, sudden death, nonfatal cardiovascular events, and nonfatal stroke, between populations with and without carotid atherosclerosis. To test this hypothesis, the authors analyzed 493 patients (mean age 67.9 years, 47.5% men) from the J-HOP (Japan Morning Surge-Home Blood Pressure) study for whom ambulatory BP monitoring and carotid intima-media thickness data were available. Twenty-nine cardiovascular events occurred during follow-up (1867 person-years). A nondipping BP pattern was independently associated with cardiovascular events in the population without carotid atherosclerosis, defined as carotid intima media thickness < 1.1 mm after adjustment for other cardiovascular risk factors including age, sex, diabetes mellitus, chronic kidney disease, and 24-hour systolic BP (hazard ratio, 8.15; 95% confidence interval, 1.76-37.78 [P < .01]). This association was not found in the population with carotid intima-media thickness >= 1.1 mm. Therefore, in the hypertensive population without carotid atherosclerosis, physicians should consider ambulatory BP monitoring to determine the nocturnal BP pattern as an alternative approach to assessing cardiovascular events. PMID- 29450968 TI - Knowledge about traumatic dental injuries in the permanent dentition: A survey of Lithuanian dentists. AB - BACKGROUND/AIMS: In Lithuania, dental trauma cases are often treated by general dentists, but it is unknown whether their age, self-evaluation of trauma knowledge and practice location can predict their actual knowledge and management of trauma cases. The aim of this study was to evaluate whether these factors can be used to predict the actual knowledge and management of trauma cases. METHODS: A 2-part questionnaire included 17 multiple-choice questions about practitioners' demographics, their self-evaluated knowledge and how frequently they treated traumatized permanent teeth as well as 13 clinical scenarios reflecting a variety of clinical trauma cases and their complications. A total of 980 randomly selected general dentists, representing 5 Lithuanian counties, participated in the study. RESULTS: The response rate was 59.4% (n = 582). Overall, 82.3% of general dentists reported that they treated only a few dental trauma cases and 14.4% chose to refer their patients; 55.1% of dentists considered their dental traumatology knowledge to be sufficient but incomplete and 34.0% self-evaluated their knowledge as insufficient. The most knowledge (based on self-evaluation) was reported by the younger dentists (<=50 years; P = .004). The mean correct knowledge score was 7.6 +/- 2.2 of the 13 clinical scenarios. Both bivariate and multivariate analyses showed that greater trauma-related knowledge was associated with a younger age. Better knowledge was observed amongst the dentists who self evaluated their own knowledge as sufficient or as comprehensive. CONCLUSION: Lithuanian general dentists have insufficient dental traumatology knowledge. Better knowledge was observed amongst younger dentists (<=50 years). PMID- 29450969 TI - Layer-by-Layer Decoupling of Twisted Graphene Sheets Epitaxially Grown on a Metal Substrate. AB - The electronic properties of graphene can be efficiently altered upon interaction with the underlying substrate resulting in a dramatic change of charge carrier behavior. Here, the evolution of the local electronic properties of epitaxial graphene on a metal upon the controlled formation of multilayers, which are produced by intercalation of atomic carbon in graphene/Ir(111), is investigated. Using scanning tunneling microscopy and Landau-level spectroscopy, it is shown that for a monolayer and bilayers with small-angle rotations, Landau levels are fully suppressed, indicating that the metal-graphene interaction is largely confined to the first graphene layer. Bilayers with large twist angles as well as twisted trilayers demonstrate a sequence of pronounced Landau levels characteristic for a free-standing graphene monolayer pointing toward an effective decoupling of the top layer from the metal substrate. These findings give evidence for the controlled preparation of epitaxial graphene multilayers with a different degree of decoupling, which represent an ideal platform for future electronic and spintronic applications. PMID- 29450970 TI - Direct Imaging of Space-Charge Accumulation and Work Function Characteristics of Functional Organic Interfaces. AB - The tailoring of organic systems is crucial to further extend the efficiency of charge transfer mechanisms and represents a cornerstone for molecular device technologies. However, this demands control of electrical properties and understanding of the physics behind organic interfaces. Here, a quantitative spatial overview of work function characteristics for phthalocyanine architectures on Au substrates is provided via kelvin probe microscopy. While macroscopic investigations are very informative, the current approach offers a nanoscale spatial rendering of electrical characteristics which is not possible to attain via conventional techniques. Interface dipole is observed due to the formation of charge accumulation layers in thin F16 CuPc, F16 CoPc, and MnPc films, displaying work functions of 5.7, 6.1, and 5.0 eV, respectively. The imaging and quantification of interface locations with significant surface potential and work function response (<0.33 eV for material thickness <1 nm) show also a dependency on the crystalline state of the organic systems. The work function mapping suggests space-charge carrier regions of about 4 nm at the organic interface. This reveals rich spatial electric parameters and ambipolar characteristics that may drive electrical performance at device scales, opening a realm of possibilities toward the development of functional organic architectures and its applications. PMID- 29450971 TI - Evaluation of an abutment-level superpower sound processor for bone-anchored hearing. AB - OBJECTIVES: Performance of an abutment-level superpower sound processor for bone anchored hearing, the Ponto 3 SuperPower from Oticon Medical (BCD2), was compared to an earlier model from Oticon Medical (BCD1). DESIGN: A comparative study in which each patient serves as its own control. SETTING: Tertiary clinic. PARTICIPANTS: Eighteen experienced BCD1 users with profound mixed hearing loss. MAIN OUTCOME MEASURES: Speech reception thresholds in noise; APHAB and SSQ questionnaires. RESULTS: In a group of 18 patients with severe mixed hearing loss, the performance of a recently introduced bone conduction device (BCD2) is evaluated relative to that of an earlier model (BCD1). Speech reception thresholds for the sentence-in-noise test in the speech and noise frontal condition are not significantly different (P > .05) for BCD1 and BCD2. Speech reception thresholds for frontal speech and three identical noise sources are 1.7 dB lower for BCD2 than for BCD1 (P < .05). With the APHAB questionnaire, the score for background noise is significantly lower (P < .01), that is more favourable, for BCD2 than for BCD1 with an effect size of 0.91. The APHAB domain scores for ease-of-communication, reverberation and aversiveness of loud sounds are not significantly different for both devices (P > .05). Scores for the speech, spatial and quality of hearing domains of the SSQ questionnaire are significantly higher (P < .01), that is more favourable, for BCD2 than for BCD1 with effect sizes of 1.22, 0.71 and 1.05, respectively. Scores for the SSQ factors "speech understanding," "spatial," "clarity, separation and identification" and "listening effort and concentration" were all significantly higher (P < .05) for BCD2 than for BCD1, with effect sizes of 1.28, 0.64, 0.98 and 0.78, respectively. On a proprietary questionnaire, 16 patients indicate a preference for BCD2 over BCD1 for conversations in a small group and two patients have no preference for either device. In a large group, one patient prefers BCD1, six patients have no preference, and eleven patients prefer BCD2. When listening to music, all patients prefer BCD2 over BCD1, with a strong preference for BCD2 for seven patients. When asked for an overall preference, all patients prefer BCD2 over BCD1, with nine patients strongly preferring BCD2. CONCLUSIONS: The lower speech reception thresholds in noise with BCD2 relative to BCD1 can be attributed to the "speech omni" directionality mode of BCD2. The combination of an improved directionality for primarily low-level inputs and a higher maximum force output, relevant for mid- and high-level inputs, results in a clear preference for BCD2 over BCD1.

AB - With high binding affinity, porous structures, safety, green, programmability, etc., DNA hydrogels have gained increasing recognition in the environmental field, i.e., advanced treatment technology of water and analysis of specific pollutants. DNA hydrogels have been demonstrated as versatile potential adsorbents, immobilization carriers of bioactive molecules, catalysts, sensors, etc. Moreover, altering components or choosing appropriate functional DNA optimizes environment-oriented hydrogels. However, the lack of comprehensive information hinders the continued optimization. The principle used to fabricate the most suitable hydrogels in terms of the requirements is the focus of this Review. First, different fabrication strategies are introduced and the ideal characteristic for environmental applications is in focus. Subsequently, recent environmental applications and the development of diverse DNA hydrogels regarding their synthesis mechanism are summarized. Finally, the Review provides an insight into the remaining challenging and future perspectives in environmental applications. PMID- 29450973 TI - Difference between renal and splenic resistive index as a novel criterion in Doppler evaluation of renal artery stenosis. AB - Detection of renal artery stenosis (RAS) using Doppler is difficult to evaluate, particularly under conditions such as bilateral RAS or difficultly accessible renal arteries (RA). The objective of the present study was to assess the utility of splenic arterial compared to renal flow as an additional parameter in the Doppler evaluation of RAS. The difference between the resistive indices (RI) determined in renal and splenic parenchymal arteries (DeltaRIK-S ) was evaluated in 181 hypertensive subjects without any evidence of RAS. Subsequently 47 RA in 24 patients with suspected RAS were angiographically assessed. A DeltaRIK-S of 0.055 (median) was determined in the population without any evidence of RAS similar to RA with angiographically excluded stenosis (DeltaRIK-S 0.068). In contrast, in angiographic proven RAS, DeltaRIK-S was significantly lower (-0.050; P < .005). The assessment of the DeltaRIK-S , proved to be an easily feasible parameter, which improves the diagnostic accuracy in the detection of RAS. PMID- 29450974 TI - Effect of scaling and root planing on gingival crevicular fluid cytokine/chemokine levels in smokers with chronic periodontitis: A systematic review. AB - In the present study, the impact of scaling and root planing (SRP) on gingival crevicular fluid (GCF) cytokine/chemokine levels in smokers with chronic periodontitis was assessed. The PICO (population, intervention, comparison, outcome) question was: In smokers with chronic periodontitis (population), what is the effect of SRP (intervention) in comparison to SRP in non-smokers with chronic periodontitis (comparison) on the GCF cytokine/chemokine level (outcome)? Indexed databases were searched up to September 2017. Of 4330 titles, nine studies reporting the levels of 13 different cytokines/chemokines were included. Eight studies had a moderate risk of bias, while one study had a high risk of bias. Almost all cytokines/chemokines were pro-inflammatory cytokines. Five cytokines/chemokines studied in four clinical studies were decreased in the smoker-chronic periodontitis group following SRP. One study observed that the GCF levels of interleukin-17 increased, while anti-inflammatory osteoprotegerin was reduced in both the SCP and non-smoker-chronic periodontitis groups at follow up. However, the majority of cytokines/chemokines did not change in the SCP groups at follow up. The current weight of evidence is not sufficient to prove that SRP has an impact on GCF cytokine/chemokine profile in smokers with chronic periodontitis. Evaluation of wide panels of pro-inflammatory cytokines/chemokines related to collagen degradation and alveolar bone destruction in future studies are warranted. PMID- 29450975 TI - Tropoelastin Implants That Accelerate Wound Repair. AB - A novel, pure, synthetic material is presented that promotes the repair of full thickness skin wounds. The active component is tropoelastin and leverages its ability to promote new blood vessel formation and its cell recruiting properties to accelerate wound repair. Key to the technology is the use of a novel heat based, stabilized form of human tropoelastin which allows for tunable resorption. This implantable material contributes a tailored insert that can be shaped to the wound bed, where it hydrates to form a conformable protein hydrogel. Significant benefits in the extent of wound healing, dermal repair, and regeneration of mature epithelium in healthy pigs are demonstrated. The implant is compatible with initial co-treatment with full- and split-thickness skin grafts. The implant's superiority to sterile bandaging, commercial hydrogel and dermal regeneration template products is shown. On this basis, a new concept for a prefabricated tissue repair material for point-of-care treatment of open wounds is provided. PMID- 29450977 TI - Self-Template-Directed Metal-Organic Frameworks Network and the Derived Honeycomb Like Carbon Flakes via Confinement Pyrolysis. AB - Metal-organic frameworks (MOFs) have become a research hotspot since they have been explored as convenient precursors for preparing various multifunctional nanomaterials. However, the preparation of MOF networks with controllable flake morphology in large scale is not realized yet. Herein, a self-template strategy is developed to prepare MOF networks. In this work, layered double-metal hydroxide (LDH) and other layered metal hydroxides are used not only as a scaffold but also as a self-sacrificed metal source. After capturing the abundant metal cations identically from the LDH by the organic linkers, MOF networks are in situ formed. It is interesting that the MOF network-derived carbon materials retain the flake morphology and exhibit a unique honeycomb-like macroporous structure due to the confined shrinkage of the polyhedral facets. The overall properties of the carbon networks are adjustable according to the tailored metal compositions in LDH and the derived MOFs, which are desirable for target-oriented applications as exemplified by the electrochemical application in supercapacitors. PMID- 29450976 TI - High Adherence to System-Level Performance Measures for Rheumatoid Arthritis in a National Early Arthritis Cohort Over Eight Years. AB - OBJECTIVE: To assess adherence to 3 system-level performance measures in a national early rheumatoid arthritis (RA) cohort. METHODS: Patients enrolled in the Canadian Early Arthritis Cohort (2007-2015) who met 1987 or 2010 American College of Rheumatology/European League Against Rheumatism criteria with <1 year of symptom duration and >=1 year of followup after enrollment were included. Performance measures assessed were the percentage of RA patients seen in yearly followup, and the number of gaps between visits of >12 or >14 months, the percentage of RA patients treated with a disease-modifying antirheumatic drug (DMARD), and days from RA diagnosis to initiation of a DMARD. Results are shown stratified by enrollment year to assess for temporal changes in performance. RESULTS: A total of 1,763 early RA patients were included (mean age 54 years, 73% female, and 82% white). At enrollment, mean +/- SD disease duration was 6 +/- 3 months, and Disease Activity Score in 28 joints was 5.1 +/- 1.5. Over 8 years, the proportion of patients seen in annual followup declined from 100% to 91%. Over followup, 42% of patients had 0 gaps in care of >12 months, and 64% had 0 gaps >14 months. The percentage of DMARD-treated early RA patients was and remained high (95-87%), and the percentage receiving DMARDs within 14 days of diagnosis was 75%. Median time-to-DMARD therapy was 1 day, indicating DMARDs were initiated at diagnosis (90th percentile 93 days). CONCLUSION: There was evidence of high adherence to system-level performance measures in this early RA cohort following a protocol. Small declines in performance were noted with increasing length of patient followup. Our findings are useful for performance measure benchmarking. PMID- 29450978 TI - Prognostic comparison of the 7th and 8th editions of the American Joint Committee on Cancer staging system for intrahepatic cholangiocarcinoma. AB - BACKGROUND: Several important changes were made to the 8th edition of the American Joint Committee on Cancer (AJCC) tumor staging system for intrahepatic cholangiocarcinoma (ICC). We assessed the prognostic impact of this new tumor staging system compared to the 7th edition. METHODS: A retrospective single institution study was performed with 626 patients who underwent R0 resection for ICC over 20-year period. RESULTS: Anatomical resection and concurrent bile duct resection were performed in 571 (91.2%) and 62 (9.9%) patients, respectively. Cumulative tumor recurrence and patient survival rates were 40.6% and 73.3% at 1 year; 66.7% and 43.8% at 3 years; 73.6% and 30.4% at 5 years; and 74.4% and 20.3% at 10 years, respectively. Independent prognostic factors for tumor recurrence and patient survival were multiple tumors, carbohydrate antigen 19-9 >200 U/ml, tumor size >5 cm, direct invasion to extrahepatic structure, and lymph node metastasis. For tumor-node-metastasis stages in the 7th versus the 8th editions, concordance index was 0.615 and 0.625 for tumor recurrence and 0.626 and 0.628 for patient survival, respectively. CONCLUSIONS: The 8th edition of the AJCC staging system appears to provide high prognostic contrast for T stage categories, except for T3. However, overall prognostic performance of the 8th edition was not markedly improved over the 7th edition. PMID- 29450979 TI - Guidance on home blood pressure monitoring: A statement of the HOPE Asia Network. AB - Hypertension is an important modifiable cardiovascular risk factor and a leading cause of death throughout Asia. Effective prevention and control of hypertension in the region remain a significant challenge despite the availability of several regional and international guidelines. Out-of-office measurement of blood pressure (BP), including home BP monitoring (HBPM), is an important hypertension management tool. Home BP is better than office BP for predicting cardiovascular risk and HBPM should be considered for all patients with office BP >= 130/85 mm Hg. It is important that HBPM is undertaken using a validated device and patients are educated about how to perform HBPM correctly. During antihypertensive therapy, monitoring of home BP control and variability is essential, especially in the morning. This is because HBPM can facilitate the choice of individualized optimal therapy. The evidence and practice points in this document are based on the Hypertension Cardiovascular Outcome Prevention and Evidence (HOPE) Asia Network expert panel consensus recommendations for HBPM in Asia. PMID- 29450981 TI - Nurr1 promotes neurogenesis of dopaminergic neuron and represses inflammatory factors in the transwell coculture system of neural stem cells and microglia. AB - INTRODUCTION: Neural stem cells (NSCs) are the most promising cells for cell replacement therapy for Parkinson's disease (PD). However, a majority of the transplanted NSCs differentiated into glial cells, thereby limiting the clinical application. Previous studies indicated that chronic neuroinflammation plays a vital role in the degeneration of midbrain DA (mDA) neurons, which suggested the developing potential of therapies for PD by targeting the inflammatory processes. Thus, Nurr1 (nuclear receptor-related factor 1), a transcription factor, has been referred to play a pivotal role in both the differentiation of dopaminergic neurons in embryonic stages and the maintenance of the dopaminergic phenotype throughout life. AIM: This study investigated the effect of Nurr1 on neuroinflammation and differentiation of NSCs cocultured with primary microglia in the transwell coculture system. RESULTS: The results showed that Nurr1 exerted anti-inflammatory effects and promoted the differentiation of NSCs into dopaminergic neurons. CONCLUSIONS: The results suggested that Nurr1 protects dopaminergic neurons from neuroinflammation insults by limiting the production of neurotoxic mediators by microglia and maintain the survival of transplanted NSCs. These phenomena provided a new theoretical and experimental foundation for the transplantation of Nurr1-overexpressed NSCs as a potential treatment of PD.

AB - Enteric methane (CH4 ) production from cattle contributes to global greenhouse gas emissions. Measurement of enteric CH4 is complex, expensive, and impractical at large scales; therefore, models are commonly used to predict CH4 production. However, building robust prediction models requires extensive data from animals under different management systems worldwide. The objectives of this study were to (1) collate a global database of enteric CH4 production from individual lactating dairy cattle; (2) determine the availability of key variables for predicting enteric CH4 production (g/day per cow), yield [g/kg dry matter intake (DMI)], and intensity (g/kg energy corrected milk) and their respective relationships; (3) develop intercontinental and regional models and cross validate their performance; and (4) assess the trade-off between availability of on-farm inputs and CH4 prediction accuracy. The intercontinental database covered Europe (EU), the United States (US), and Australia (AU). A sequential approach was taken by incrementally adding key variables to develop models with increasing complexity. Methane emissions were predicted by fitting linear mixed models. Within model categories, an intercontinental model with the most available independent variables performed best with root mean square prediction error (RMSPE) as a percentage of mean observed value of 16.6%, 14.7%, and 19.8% for intercontinental, EU, and United States regions, respectively. Less complex models requiring only DMI had predictive ability comparable to complex models. Enteric CH4 production, yield, and intensity prediction models developed on an intercontinental basis had similar performance across regions, however, intercepts and slopes were different with implications for prediction. Revised CH4 emission conversion factors for specific regions are required to improve CH4 production estimates in national inventories. In conclusion, information on DMI is required for good prediction, and other factors such as dietary neutral detergent fiber (NDF) concentration, improve the prediction. For enteric CH4 yield and intensity prediction, information on milk yield and composition is required for better estimation.

AB - This retrospective cohort study of 95 957 patients from a large integrated healthcare organization was conducted to examine whether the frequency and intervals between outpatient encounters were associated with achieving blood pressure (BP) control. Patients were followed up until they were censored or achieved BP control up to 1 year. Additionally, this study examined the time to BP control. On average, follow-up was significantly longer in patients with uncontrolled BP at 292.9 days compared with 232.2 days in those with BP control. The controlled BP group had significantly more encounters on average compared with the uncontrolled BP group (4.1 vs 3.1, standardized difference 0.33). As the number of days increased between encounters from the 1 to < 14 days, there was a consistently lower likelihood of achieving BP control. Encounter intervals of >=180 days were associated with the lowest likelihood of achieving BP control. These findings suggest that there may be an optimal number of encounters to benefit patients with hypertension.

AB - In this study, the chloroform-soluble extract of Cuscuta auralis was separated successfully using off-line two-dimensional high-performance countercurrent chromatography, yielding a gamma-pyrone, two alkaloids, a flavonoid, and four lignans. The first-dimensional countercurrent separation using a methylene chloride/methanol/water (11:6:5, v/v/v) system yielded three subfractions (fractions I-III). The second-dimensional countercurrent separations, conducted on fractions I-III using n-hexane/ethyl acetate/methanol/water/acetic acid (5:5:5:5:0, 3:7:3:7:0, and 1:9:1:9:0.01, v/v/v/v/v) systems, gave maltol (1), (-) (13S)-cuscutamine (2), (+)-(13R)-cuscutamine (3), (+)-pinoresinol (4), (+) epipinoresinol (5), kaempferol (6), piperitol (7), and (9R)-hydroxy-d-sesamin (8). To the best of our knowledge, maltol was identified for the first time in Cuscuta species. Furthermore, this report details the first full assignment of spectroscopic data of two cuscutamine epimers, (-)-(13S)-cuscutamine and (+) (13R)-cuscutamine. PMID- 29450984 TI - Computational studies on horseshoe shape pocket of human orexin receptor type 2 and boat conformation of suvorexant by molecular dynamics simulations. AB - The FDA approved drug suvorexant binds to the horseshoe shape pocket of OX2 R with the boat conformation. The horseshoe shape pocket plays an important role on the biological activity of OX2 R in the cell membrane. To study the binding mechanism between the horseshoe shape pocket of OX2 R and boat conformation of suvorexant, the crystal structures of wild type and N324A mutant of OX2 R in complex with antagonist suvorexant are chosen to perform molecular dynamics (MD) simulations, QM/MM, and MMGBSA calculations. By comparison with the wild type of OX2 R, the results show the 1,2,3-triazole and p-toluamide groups of suvorexant are changed in the N324A mutant of OX2 R during 200 ns MD simulations. The QM/MM and weak interaction analysis are employed to calculate the non-covalent bonds interaction between suvorexant and key residues in the wild type and N324A mutant of OX2 R. The MMGBSA calculations indicate the entropy energy is an important influence factor for suvorexant affinity in the distorted horseshoe shape pocket of OX2 R. Our results not only show the horseshoe shape pocket of OX2 R is the necessary conformation for the binding of antagonist suvorexant, but also give the important sites and structural features for antagonist design of OX2 R.

PMID- 29450985 TI - Effect of secondary electron generation on dose enhancement in Lipiodol with and without a flattening filter. AB - PURPOSE: Lipiodol, which was used in transcatheter arterial chemoembolization before liver stereotactic body radiation therapy (SBRT), remains in SBRT. Previous we reported the dose enhancement in Lipiodol using 10 MV (10*) FFF beam. In this study, we compared the dose enhancement in Lipiodol and evaluated the probability of electron generation (PEG) for the dose enhancement using flattening filter (FF) and flattening filter free (FFF) beams. METHODS: FF and FFF for 6 MV (6*) and 10* beams were delivered by TrueBeam. The dose enhancement factor (DEF), energy spectrum, and PEG was calculated using Monte Carlo (MC) code BEAMnrc and heavy ion transport code system (PHITS). RESULTS: DEFs for FF and FFF 6* beams were 7.0% and 17.0% at the center of Lipiodol (depth, 6.5 cm). DEFs for FF and FFF 10* beams were 8.2% and 10.5% at the center of Lipiodol. Spectral analysis revealed that the FFF beams contained more low-energy (0-0.3 MeV) electrons than the FF beams, and the FF beams contained more high-energy (>0.3 MeV) electrons than the FFF beams in Lipiodol. The difference between FFF and FF beam DEFs was larger for 6* than for 10*. This occurred because the 10* beams contained more high-energy electrons. The PEGs for photoelectric absorption and Compton scattering for the FFF beams were higher than those for the FF beams. The PEG for the photoelectric absorption was higher than that for Compton scattering. CONCLUSIONS: FFF beam contained more low-energy photons and it contributed to the dose enhancement. Energy spectra and PEGs are useful for analyzing the mechanisms of dose enhancement.

AB - Postnasal drip (PND)-related cough is a very common symptom in patients with upper respiratory tract infections (URTIs). At present, there is not a standard treatment for postnasal drip and postnasal drip-related cough. The aim of this pilot study was to evaluate the efficacy of a specific salso-bromo-iodine thermal water containing hyaluronic acid and grapefruit seed extract (SBI-H-GSE) comparing it with a normal saline solution in children with URTIs who refer PND related symptoms. The study was randomized, single-blind, and controlled. Study group (75 children) was treated with SBI-H-GSE and control group (65 children) was treated with a normal saline solution; both compounds were administered by nasal nebulization with Rinowash nasal douche twice/day for 10 days a month for 3 consecutive months. Parent Cough-Specific Quality of Life questionnaire (PC-QOL) average score, the prevalence of symptoms and signs related to post-nasal drip, nasal mucociliary transport time (NMTT), duration and number of URTI episodes, antibiotic usage and days of absence from school were evaluated at baseline and after treatment. SBI-H-GSE therapy shows better and statistically significant trend after treatment when compared to control group for PC-QOL average score (p=0.011), NMTT (p=0.047), symptoms and signs related to post-nasal drip (all p<0.005, except for the cobblestone appearance of the mucosa), duration (in days) with URTI symptoms (p=0.023) and a usage of antibiotic therapy (p=0.011). The current randomized-controlled pilot study demonstrated that SBI-H-GSE solution was effective in the treatment of children with URTIs who refer PND-related symptoms.

AB - Splicing factor RBM10 and its close homologues RBM5 and RBM6 govern the splicing of oncogenes such as Fas, NUMB, and Bcl-X. The molecular architecture of these proteins includes zinc fingers (ZnFs) and RNA recognition motifs (RRMs). Three of these domains in RBM10 that constitute the RNA binding part of this splicing factor were found to individually bind RNAs with micromolar affinities. It was thus of interest to further investigate the structural basis of the well documented high-affinity RNA recognition by RMB10. Here, we investigated RNA binding by combinations of two or three of these domains and discovered that a polypeptide containing RRM1, ZnF1, and RRM2 connected by their natural linkers recognizes a specific sequence of the Fas exon 6 mRNA with an affinity of 20 nM. Nuclear magnetic resonance structures of the RBM10 domains RRM1 and ZnF1 and the natural V354del isoform of RRM2 further confirmed that the interactions with RNA are driven by canonical RNA recognition elements. The well-known high-fidelity RNA splice site recognition by RBM10, and probably by RBM5 and RBM6, can thus be largely rationalized by a cooperative binding action of RRM and ZnF domains. PMID- 29450991 TI - Mass Spectrometry-Based Fast Photochemical Oxidation of Proteins (FPOP) for Higher Order Structure Characterization. AB - Assessment of protein structure and interaction is crucial for understanding protein structure/function relationships. Compared to high-resolution structural tools, including X-ray crystallography, nuclear magnetic resonance (NMR), and cryo-EM, and traditional low-resolution methods, such as circular dichroism, UV vis, and florescence spectroscopy, mass spectrometry (MS)-based protein footprinting affords medium-to-high resolution (i.e., regional and residue specific insights) by taking advantage of proteomics methods focused on the primary structure. The methodology relies on "painting" the reactive and solvent exposed amino acid residues with chemical tags and using the pattern of modifications as footprints from analysis by bottom-up MS-based proteomics to deduce protein higher order structures. The outcome can refer to proteins in solution or even in cells and is complementary to those of X-ray crystallography and NMR. It is particularly useful in mapping protein-ligand interfaces and conformational changes resulting from ligand binding, mutation, and aggregation. Fast photochemical oxidation of proteins (FPOP), in its original conception, is a type of hydroxyl-radical-based protein footprinting that utilizes a pulsed KrF laser (248 nm) to trigger hydrolysis of hydrogen peroxide to produce solution hydroxyl radicals, which subsequently modify the protein in situ. The platform is expanding to adopt other reactive species including carbenes. The reactivity of the probe depends on the intrinsic reactivity of the radical with the residue side chain and the solvent accessibility of the residue as a function of the tertiary/quaternary structures. By introducing an appropriate scavenger to compete with hydroxyl radical self-quenching, the lifetime of the primary radicals is remarkably shortened to approximately microsecond. Thus, the sampling time scale of FPOP is much faster than hydrogen-deuterium exchange and other covalent labeling methods relying on nonradical reactions. The short footprinting time scale of FPOP offers two major advantages for protein structure elucidation: (1) it allows the protein to be interrogated in its native or near-native state with minimum structural perturbation; (2) it exhibits high sensitivity toward alterations in protein higher order structures because its sampling time is short with respect to protein conformational changes and dynamic motion. In addition, the covalent and irreversible oxidation by the hydroxyl radical provides more flexibility in the downstream proteomics workflow and MS analysis, permitting high spatial resolution with residue-specific information. Since its invention in 2005 by Hambly and Gross, FPOP has developed from proof-of-concept to a valuable biophysical tool for interrogating protein structure. In this Account, we summarize the principles and experimental design of FPOP that enable its fast labeling and describe the current and unique capabilities of the technique in protein higher order structure elucidation. Application examples include characterization of amyloid beta self-assembly, protein-ligand interactions with a special emphasis on epitope mapping for protein therapeutics (e.g., antibody, Fab, and adnectin), protein folding detailed to residue-specific folding kinetics, and protein flexibility/dynamics. Additionally, the utility of FPOP based oxidative footprinting should grow with our continuing developments of novel reagents (e.g., sulfate radical anion, carbene diradical, and trifluoromethyl radical). These reactive reagents are compatible with the current FPOP platform and offer different reactivity and selectivity toward various types of amino acid residues, providing complementary insights into protein higher order structures for soluble proteins and ultimately for membrane-bound proteins. PMID- 29450992 TI - Assessment of Fragmentation Strategies for Large Proteins Using the Multilayer Molecules-in-Molecules Approach. AB - We present a rigorous evaluation of the potential for the multilayer Molecules-in Molecules (MIM) fragmentation method to be applied to large biomolecules. Density functional total energies of a test set of 8 peptides, sizes ranging from 107 to 721 atoms, were evaluated with MIM and compared to unfragmented energies to help develop a protocol for the treatment of large proteins. Fragmentation schemes involving subsystems of 4 to 5 covalently bonded fragments (tetramer or pentamer schemes) were tested with a single level of theory (MIM1) and produced errors on the order of 100 kcal/mol due to the relatively small size of the subsystems and the neglect of nonbonded interactions. Supplementing the two schemes with nonbonded dimer subsystems, formed from fragments within a specified cutoff distance (3.0 A), nearly cut the MIM1 errors in half, leading us to employ these new schemes as starting points in multilayer calculations. When employing a DFT low level with a substantially smaller basis set (MIM2), the dimer-supplemented schemes produce errors below our target accuracy of 2 kcal/mol in the majority of cases. However, for the larger test systems, such as the 45 residue slice of a human protein kinase with over 10,000 basis functions in the high level, the low level calculation over the full molecule becomes the bottleneck for MIM2 calculations. To overcome any associated limitations, we explored, for the first time, 3-layer MIM methods (MIM3) with a distance-based medium level of fragmentation and dispersion-corrected semiempirical methods (e.g., PM6-D3) as the low level. A modestly sized cutoff distance in the medium level (3.0-3.5 A), leading to subsystems of 30-50 atoms treated at the medium and low levels of theory, was able to match the low errors of the MIM2 calculations. These results allow us to develop a general prescription for 3-layer calculations wherein a much cheaper low level can be used, while fragment sizes in the high layer stay modest, allowing the MIM method to be applied to very large proteins in the future. PMID- 29450993 TI - Near Infrared Photoimmunotherapy with Combined Exposure of External and Interstitial Light Sources. AB - Near infrared photoimmunotherapy (NIR-PIT) is a new target-cell-specific cancer treatment that induces highly selective necrotic/immunogenic cell death after systemic administration of a photoabsorber antibody conjugate and subsequent NIR light exposure. However, the depth of NIR light penetration in tissue (approximately 2 cm) with external light sources limits the therapeutic effects of NIR-PIT. Interstitial light exposure using cylindrical diffusing optical fibers can overcome this limitation. The purpose in this study was to compare three NIR light delivery methods for treating tumors with NIR-PIT using a NIR laser system at an identical light energy; external exposure alone, interstitial exposure alone, and the combination. Panitumumab conjugated with the photoabsorber IRDye-700DX (pan-IR700) was intravenously administered to mice with A431-luc xenografts which are epithelial growth factor receptor (EGFR) positive. One and 2 days later, NIR light was administered to the tumors using one of three methods. Interstitial exposure alone and in combination with external sources showed the greatest decrease in bioluminescence signal intensity. Additionally, the combination of external and interstitial NIR light exposure showed significantly greater tumor size reduction and prolonged survival after NIR-PIT compared to external exposure alone. This result suggested that the combination of external and interstitial NIR light exposure was more effective than externally applied light alone. Although external exposure is the least invasive means of delivering light, the combination of external and interstitial exposures produces superior therapeutic efficacy in tumors greater than 2 cm in depth from the tissue surface.

AB - Simpterpenoid A (1), an unprecedented meroterpenoid possessing a highly functionalized cyclohexadiene moiety (ring C) featuring gem-propane-1,2-dione and methylformate groups, was characterized from mangrove-derived Penicillium simplicissimum MA-332. Due to the highly oxygenated and functionalized ring C and lack of some key correlations, the unambiguous assignment of the planar structure and steric configuration was solved by X-ray crystallographic analysis. Compound 1 exhibited inhibitory activity against influenza neuraminidase in nanomolar quantities.

AB - Resonance energies and proton affinities of N-acyl-glutarimides, compared with related twisted acyclic amides of relevance to N-C(O) cross-coupling, are reported. The data demonstrate that amidic resonance in N-acyl-glutarimides practically disappears (ER < 2.8 kcal/mol), while, intriguingly, these amides favor O-protonation despite significant twist. In some cases, N-acyl-glutarimides undergo intramolecular N- to O-acyl migration, indicative of high capacity as acylating reagents. The understanding provided for the high reactivity of N-acyl glutarimides should facilitate the development of a broadly general N-C(O) amide activation platform.

AB - A copper-catalyzed C(sp)-C(sp3) coupling reaction between terminal alkynes and alkylsilyl peroxides is reported. In the presence of a copper catalyst and 4 dimethylaminopyridine, the reaction smoothly affords a variety of internal alkynes by coupling alkylsilyl peroxides and terminal alkynes. Mechanistic studies suggest that the reaction proceeds via a radical mechanism, whereby the alkyl radicals are generated from the alkylsilyl peroxides.

AB - AIM: There is no commercially available urinary cystatin-C (u-CYSC) test in the market. Therefore, we optimized and validated an automated immune turbidimetric test for u-CYSC measurements and investigated u-CYSC concentrations in acute and chronic diseases which might lead to renal tubular disorders. MATERIALS & METHODS: A particle-enhanced immune turbidimetric assay was adapted and validated on a Cobas 8000/c502 analyzer. Urine samples of different patient groups were also analyzed. RESULTS: Our method showed excellent analytical performance. U CYSC/u-creatinine (u-CREAT) was higher in sepsis-related acute kidney injury group (p < 0.001) compared with controls and to patients with chronic hypertension and Type 2 diabetes. CONCLUSION: We validated a fast, sensitive, fully automated u-CYSC assay which is ideal for routine use and might be a potential complementary laboratory test to evaluate renal tubular function.

AB - AIM: Liquid-liquid extraction is widely used in therapeutic drug monitoring of antipsychotics, but difficulties in automation of the technique can result in long operational time. In this paper, parallel artificial liquid membrane extraction was used for extraction of serotonin- and serotonin-norepinephrine reuptake inhibitors from human plasma, and an approach to automate the technique was investigated. RESULTS: Eight model analytes were extracted from 125 MUl human plasma with recoveries in the range 72-111% (relative standard deviation [RSD] <=12.8%). A semiautomated pipettor was successfully utilized in the procedure, reducing the manual handling time. Real patient samples were analyzed with satisfying accuracy. CONCLUSION: A semiautomated extraction of serotonin-and serotonin-norepinephrine reuptake inhibitors by parallel artificial liquid membrane extraction extraction was successfully performed.

AB - Within a preventive framework, we outline a school-based intervention aimed at strengthening skills of survival and psychological functioning in children who have experienced war and political violence in the Gaza Strip. In accordance with a socio-ecological perspective on wellbeing and resilience, the pilot study aimed at evaluating the outcomes of a psychosocial narrative school-based intervention with a group of school-aged children in the aftermath of war. The intervention was oriented at empowering positive emotions, life satisfaction, and optimism in children as protective factors in preventing posttraumatic reactions after war. Findings showed the efficacy of the intervention in favoring life satisfaction in different ecological domains. Children in the intervention group showed greater appreciation for friends, school, family, themselves, and their living environment. At the end of the activity, children were increased the level of positive emotions, but negative feelings were stronger than before the narrative intervention. Clinical implications and future direction or community work are, then, discussed. PMID- 29451003 TI - Escherichia coli isolates from femoral bone marrow of broilers exhibit diverse pheno- and genotypic characteristics that do not correlate with macroscopic lesions of bacterial chondronecrosis with osteomyelitis. AB - The pheno- and genotypic relatedness among Escherichia coli isolates from broilers with and without macroscopic lesions of the femoral head were investigated. In total, 219 isolates obtained from the bone marrow were characterized by serotyping, antimicrobial resistance (AMR) profiles, phylogenetic grouping, detection of virulence-associated genes (VAGs) and pulsed field gel electrophoresis (PFGE). Serotyping revealed that 48.4% of the isolates were assigned to one of the three serotypes (O78:K80: 21.0%, O2:K1: 18.7%, O1:K1: 8.7%). Substantial phenotypic variation was also noticed in AMR testing as most of the birds harboured E. coli isolates with different AMR profiles, which is of high clinical relevance. The majority of isolates could be classified into phylogenetic groups D (54.3%) and B2 (25.6%), followed by A (11.4%) and B1 (8.7%). Virulotyping showed that the highest number of isolates contained genes iucD (86.8%) and iss (84.9%), whereas papC (16.0%) and astA (12.3%) were present in least number of isolates. PFGE resulted in 58 different profiles from 200 typeable isolates. No correlation was found between specific serotypes, AMR profiles, phylogenetic groups, PFGE types or VAG profiles of E. coli and the occurrence of bacterial chondronecrosis with osteomyelitis, contradicting the hypothesis of a specific bacterial pheno- or genotype being involved in the disease. PMID- 29451004 TI - Simulating localised cellular inflammation and substrate properties in a strain energy density based bone remodelling algorithm for use in modelling trauma. AB - Bone responds to mechanical stimulus and a range of pre-existing finite element models have been suggested to reproduce the internal physiological structure of bone. Inflammation effects are not included in these models, yet inflammation is a key component of bone repair in trauma. Therefore, a model is proposed and tested here that extends these methods to include parameters that could be considered to represent the behaviour of bone remodelling when influenced by inflammation. The proposed model regulates remodelling based on findings from recent studies into the nature of heterotopic ossification, the formation of heterotopic bone, which have revealed information about the nature of bone after high levels of trauma. These parameters include consideration of the distance from the zone of trauma, the density of mesenchymal stem cells, and substrate stiffness as a trigger for cells becoming osteogenic. The method is tested on a two-dimensional plate model and shows that the new extended algorithm can produce a range of structures depending on inputs that could be used in the future to replicate physiological scenarios. PMID- 29451007 TI - Fractures in the Pediatric Emergency Department: Are We Considering Abuse? AB - Approximately one fourths of infant fractures are due to abuse. Recognition of abuse is important to avoid further morbidity/mortality. There is limited knowledge regarding how frequently pediatric emergency department clinicians consider abuse in infants with fractures. Our primary objective was to estimate the percentage of infants with fractures for whom abuse was considered, and to examine characteristics associated with abuse consideration. We performed a retrospective review of infants <1 year of age presenting to a pediatric emergency department. Our primary outcome variable was consideration of abuse. Our secondary outcome measures were identification of predictor variables associated with consideration of abuse. We identified 509 infants meeting study criteria. Pediatric emergency physicians considered abuse in approximately two thirds of infants with fractures. Consideration was more likely to occur in younger infants, in the presence of no history or unwitnessed injury mechanism, when evaluated by male physicians, and emergency department encounters from 12 am to 6 am. PMID- 29451006 TI - Different Indexes of Glycemic Variability as Identifiers of Patients with Risk of Hypoglycemia in Type 2 Diabetes Mellitus. AB - INTRODUCTION: Recent publications frequently introduce new indexes to measure glycemic variability (GV), quality of glycemic control, or glycemic risk; however, there is a lack of evidence supporting the use of one particular parameter, especially in clinical practice. METHODS: A cohort of type 2 diabetes mellitus (T2DM) patients in ambulatory care were followed using continuous glucose monitoring sensors (CGM). Mean glucose (MG), standard deviation, coefficient of variation (CV), interquartile range, CONGA1, 2, and 4, MAGE, M value, J index, high blood glucose index, and low blood glucose index (LBGI) were estimated. Hypoglycemia incidence (<54 mg/dl) was calculated. Area under the curve (AUC) was determined for different indexes as identifiers of patients with risk of hypoglycemia (IRH). Optimal cutoff thresholds were determined from analysis of the receiver operating characteristic curves. RESULTS: CGM data for 657 days from 140 T2DM patients (4.69 average days per patient) were analyzed. Hypoglycemia was present in 50 patients with 144 hypoglycemic events in total (incidence rate of 0.22 events per patient/day). In the multivariate analysis, both CV (OR 1.20, 95% CI 1.12-1.28, P < .001) and LBGI (OR 4.83, 95% CI 2.41 9.71, P < .001) were shown to have a statistically significant association with hypoglycemia. The highest AUC were for CV (0.84; 95% CI 0.77-0.91) and LBGI (0.95; 95% CI 0.92-0.98). The optimal cutoff threshold for CV as IRH was 34%, and 3.4 for LBGI. CONCLUSION: This analysis shows that CV can be recommended as the preferred parameter of GV to be used in clinical practice for T2DM patients. LBGI is the preferred IRH between glycemic risk indexes. PMID- 29451005 TI - HIV Infection and risk of postpartum infection, complications and mortality in rural Uganda. AB - HIV infection may increase risk of postpartum infection and infection-related mortality. We hypothesized that postpartum infection incidence and attributable mortality in Mbarara, Uganda would be higher in HIV-infected than HIV-uninfected women. We performed a prospective cohort study of 4231 women presenting to a regional referral hospital in 2015 for delivery or postpartum care. All febrile or hypothermic women, and a subset of randomly selected normothermic women were followed during hospitalization and with 6-week postpartum phone interviews. The primary outcome was in-hospital postpartum infection. Secondary outcomes included in-hospital complications (mortality, re-operation, intensive care unit transfer, need for imaging or blood transfusion) and 6-week mortality. We performed multivariable regression analyses to estimate adjusted differences in each outcome by HIV serostatus. Mean age was 25.2 years and 481 participants (11%) were HIV-infected. Median CD4+ count was 487 (IQR 325, 696) cells/mm3, and 90% of HIV-infected women (193/215 selected for in-depth survey) were on antiretroviral therapy. Overall, 5% (205/4231) of women developed fever or hypothermia. Cumulative in-hospital postpartum infection incidence was 2.0% and did not differ by HIV status (aOR 1.4, 95% CI 0.6-3.3, P = 0.49). However, more HIV-infected women developed postpartum complications (4.4% vs. 1.2%, P = 0.001). In-hospital mortality was rare (2/1768, 0.1%), and remained so at 6 weeks (4/1526, 0.3%), without differences by HIV serostatus (P = 1.0 and 0.31, respectively). For women in rural Uganda with high rates of antiretroviral therapy coverage, HIV infection did not predict postpartum infection or mortality, but was associated with increased risk of postpartum complications. PMID- 29451008 TI - Utilization of Patient Navigators in an Urban Academic Pediatric Primary Care Practice. AB - Navigating health care systems can be a challenge for families. A retrospective descriptive cohort analysis was conducted assessing referrals to patient navigators (PNs) in one urban academic pediatric primary care practice. PNs tracked referral processes and a subset of PN referrals was assessed for markers of successful referrals. The most common reasons for referral were assistance overcoming barriers to care (46%), developmental concerns (38%), and adherence/care coordination concerns (14%). Significant predictors of referral were younger age, medical complexity, public insurance, male sex, and higher rates of no-show to visits in primary or subspecialist care. The majority of referrals were resolved. The referrals for process-oriented needs were significantly more successful than those for other concerns. PNs were more effective for discrete process tasks than for those that required behavior change by patients or families. Future directions include analysis of cost effectiveness of the PN program and analysis of parent and primary care provider experience. PMID- 29451009 TI - Risk factors influencing severity of attention deficit hyperactivity disorder in a sample of preparatory school students in Cairo. AB - BACKGROUND: Attention deficit hyperactivity disorder (ADHD) is one of the most common childhood psychiatric disorders. Severity of symptoms is associated with more behavioral problems, poor academic performance, and persistence of symptoms into adulthood. METHODS: To examine the clinical and social correlates that may be identified as risk factors associated with ADHD severity in a sample of adolescent ADHD school students. A total of 925 students were recruited from two public and two private schools from eastern Cairo. They were interviewed using Conners-Wells Adolescent Self-Report-short version (CASS-S); students scoring more than 65 were further interviewed with Kiddie Schedule for Affective Disorders and Schizophrenia-present and lifetime version (K-SADS-PL) to confirm the diagnosis, then Conners-Wells Adolescent Self-Report-long version (CASS-L) to assess severity and Wechsler Intelligence Scale for Children (WISC) to ascertain intellectual ability. RESULTS: About 10.3% of cases were severe, 5.7% were moderate, and 83.9% were mild. Severity was significantly associated with female gender, psychiatric comorbidity, family problems, conduct symptoms, and poor anger management. Diagnostic and Statistical Manual of Mental Disorders (4th ed.) ( DSM-IV) hyperactive-impulsive type was the only predictive factor of ADHD severity. CONCLUSIONS: The diagnosis of hyperactive-impulsive subtype may predict the severity of ADHD symptoms.

AB - Mycoplasma gallisepticum (MG) is the primary cause of chronic respiratory disease in poultry. We investigated the protective efficacy of the live-attenuated ts-11 and 6/85 MG vaccines against a local MG strain and, in order to enhance signs and mimic a typical field situation, we co-infected birds with a virulent strain of QX-like infectious bronchitis virus (IBV). Both vaccines showed similar ability to protect infected chickens from clinical signs, although ts-11 performed slightly better. Despite the lower protection against clinical disease, 6/85 vaccinated birds had significantly (P <= 0.05) lower tracheal lesion scores and mucosal thickness at day 28 post-vaccination (7 days post-challenge [dpc] with MG, 2 dpc IBV) and day 31 post-vaccination (10 dpc MG challenge, 5 dpc IBV) compared to ts-11 vaccinated birds, but these difference was not significant at day 33 (12 dpc MG, 7 dpc IBV). Pathogen infection and replication was assessed by qPCR, and the 6/85 vaccine produced a more significant (P <= 0.05) reduction in MG replication in the lungs, kidneys and livers but enhanced late replication in bursae and caecal tonsils. In contrast, the ts-11 vaccine had a more pronounced reductive effect on replication in tracheas, air sacs, bursae and heart at days 28 and 31, yet increased replication in lungs. Interestingly, both vaccines provided non-specific protection against IBV challenge. The co-challenge model provided useful data on vaccine efficacy, especially on days 31 and 33, and tracheas, lungs, air sacs, kidneys, liver and caecal tonsils were the best organs to assess.

AB - A new polycyclic antibiotic, pradimicin-IRD, was isolated from actinobacteria Amycolatopsis sp. IRD-009 recovered from soil of Brazilian rainforest undergoing restoration area. This molecule is the major compound produced in solid culture media. The new compound was detected by a focused method of precursor ion (high performance liquid chromatography coupled to tandem mass spectrometer) developed previously to identify unusual aminoglycosyl sugar moieties. The compound was isolated and its structure was, therefore, elucidated by high-resolution mass spectrometry, and 1D and 2D nuclear magnetic resonance experiments. Pradimicin IRD displayed potential antimicrobial activity against Streptococcus agalactiae (MIC 3.1 MUg/mL), Pseudomonas aeruginosa (MIC 3.1 MUg/mL) and Staphylococcus aureus (MIC 3.1 MUg/mL), and also cytotoxicity against tumour and non-tumour cell lines with IC50 values ranging from 0.8 MUM in HCT-116 colon carcinoma cells to 2.7 MUM in MM 200 melanoma cells. Particularly, these biological properties are described for the first time for this chemical class. PMID- 29451014 TI - The MusIC method: a fast and quasi-optimal solution to the muscle forces estimation problem. AB - The present paper aims at presenting a fast and quasi-optimal method of muscle forces estimation: the MusIC method. It consists in interpolating a first estimation in a database generated offline thanks to a classical optimization problem, and then correcting it to respect the motion dynamics. Three different cost functions - two polynomial criteria and a min/max criterion - were tested on a planar musculoskeletal model. The MusIC method provides a computation frequency approximately 10 times higher compared to a classical optimization problem with a relative mean error of 4% on cost function evaluation. PMID- 29451015 TI - Chemical constituents from the rhizomes of Polygonatum sibiricum Red. and anti inflammatory activity in RAW264.7 macrophage cells. AB - Chemical investigation of the rhizomes of Polygonatum sibiricum Red. led to the identification of 27 constituents. Among them, a total of 16 compounds were obtained from Polygonatum for the first time, in which, 3 and 4 were also firstly isolated as natural products. Anti-inflammatory activity studies on 13 isolated compounds showed that beta-carboline constituents, especially compounds 1 and 2, significantly inhibited the expression of NO, TNF-alpha, IL-6 and IL-1beta in lipopolysaccharide (LPS)-treated RAW264.7 macrophage cells. Moreover, western blotting analysis demonstrated that compound 1 significantly inhibited the expression of COX-2, iNOS and the activation of NF-kappaB, suggesting that beta carboline structures may play an important role in inhibition of NF-kappaB signaling pathway, which thereby inhibits the production of inflammatory factors. The present research may not only help further elucidation of the anti inflammatory mechanism of P. sibiricum Red., but also provide the potential bioactive molecules for inflammatory diseases research. PMID- 29451016 TI - Evaluation of a New Noninvasive Glucose Monitoring Device by Means of Standardized Meal Experiments. AB - BACKGROUND:: Frequent blood glucose readings are the most cumbersome aspect of diabetes treatment for many patients. The noninvasive TensorTip Combo Glucometer (CoG) component employs dedicated mathematical algorithms to analyze the collected signal and to predict tissue glucose at the fingertip. This study presents the performance of the CoG (the invasive and the noninvasive components) during a standardized meal experiment. METHODS:: Each of the 36 participants (18 females and males each, age: 49 +/- 18 years, 14 healthy subjects, 6 type 1 and 16 type 2 patients) received a device for conducting calibration at home. Thereafter, they ingested a standardized meal. Blood glucose was assessed from capillary blood samples by means of the (non)invasive device, YSI Stat 2300 plus, Contour Next at time points -30, 0, 15, 30, 45, 60, 75, 90, 120, 150, and 180 minutes. Statistical analysis was performed by consensus error grid (CEG) and calculation of mean absolute relative difference (MARD) in comparison to YSI. RESULTS:: For the noninvasive (NI) CoG technology, 100% of the data pairs were found in CEG zones A (96.6%) and B (3.4%); 100% were seen in zone A for the invasive component and Contour Next. MARD was calculated to be 4.2% for Contour Next, 9.2% for the invasive component, and 14.4% for the NI component. CONCLUSIONS:: After appropriate individual calibration of the NI technology, both the NI and the invasive CoG components reliably tracked tissue and blood glucose values, respectively. This may enable patients with diabetes to monitor their glucose levels frequently, reliably, and most of all pain-free. PMID- 29451017 TI - Assessing Quality Control Strategies for HbA1c Measurements From a Patient Risk Perspective. AB - BACKGROUND: Current laboratory risk management principles emphasize the importance of assessing laboratory quality control (QC) practices in terms of the risk of patient harm. Limited practical guidance or examples on how to do this are available. METHODS: The patient risk model described in a published laboratory risk management guideline was combined with a recently reported approach to computing the predicted probability of patient harm to produce a risk management index (RMI) that compares the predicted probability of patient harm for a QC strategy to the acceptable probability of patient harm based on the expected severity of harm caused by an erroneously reported patient result. RESULTS: Measurement procedure capability and quality control performance for two instruments measuring HbA1c in a laboratory were assessed by computing the RMI for each instrument individually and for the laboratory as a whole. CONCLUSIONS: This assessment provides a concrete example of how laboratory QC practices can be directly correlated to the risk of patient harm from erroneously reported patient results. PMID- 29451018 TI - Incorporating dried blood spot LC-MS/MS analysis for clinical development of a novel oncolytic agent. AB - AIM: Design and execution of a dried blood spot (DBS-LC-MS/MS) assay for pharmacokinetic analyses in oncology patients. RESULTS & DISCUSSION: The methodology was validated to collect and store DBS samples from multiple clinical sites, and analyze blood with diverse hematocrit ranges (25-55) to match the potential patient population. Bridging data comparing DBS and plasma showed high degree of concordance with DBS:plasma ratios of 0.81, demonstrating no preferential uptake or association with cellular components of the blood. Pharmacokinetic analysis supporting clinical development was performed using 20 MUl of blood collected as DBS. Incurred sample reanalysis showed high correlation. CONCLUSION: Successful validation of a DBS method and implementation in the clinic enabled pharmacokinetic analysis during the clinical development of a novel oncolytic agent in oncology patients. PMID- 29451019 TI - Antimicrobial substances from the rare actinomycete Nonomuraea rhodomycinica NR4 ASC07T. AB - Nonomuraea rhodomycinica NR4-ASC07T is a rare actinomycete isolated from soil in Sirindhorn peat swamp forest. The crude extract of its culture broth exhibited antimicrobial and anticancer against diverse human pathogens and cancer cells. The chemical investigation of the crude extract led to the isolation of two new metabolites named nonomuric acid (1) and 3-hydroxy deoxydaunorubicinol aglycone (2), along with two known bioactive compounds [epsilon-rhodomycinone (3) and 7 deoxy-13-dihydrocarminomycinone (4)]. Compounds 1 and 3 showed antimalarial activity with the half maximal inhibitory concentration (IC50) of 8.00 and 8.88 MUg mL-1, respectively. Compound 4 inhibited growth of Mycobacterium tuberculosis and Bacillus cereus at the minimum inhibitory concentrations of 50.0 and 12.50 MUg mL-1, respectively. Every compound exhibited cytotoxicity against cancer cells tested at IC50 >= 6.34 MUg mL-1. These finding are the first report of bioactive metabolites produced by strain NR4-ASC07T, suggesting that rare actinomycetes are yet promising sources for novel drug discovery. PMID- 29451020 TI - The brigatinib experience: a new generation of therapy for ALK-positive non-small cell lung cancer. AB - Lung cancer remains the leading cause of cancer deaths in the world with 1.69 million deaths in 2015. A total of 85% of lung cancer cases are non-small-cell lung cancers (NSCLCs). Driver mutations associated with anaplastic lymphoma kinase (ALK) have been identified in a variety of malignancies, including NSCLC. An ALK inhibitor (crizotinib, ceritinib and alectinib) is the preferred therapeutic approach to those advanced ALK fusion variant-positive NSCLC patients. Brigatinib, a next-generation ALK inhibitor, shows promising activity in ALK-rearranged NSCLC that have previously received crizotinib with response rates in ALTA ranging from 42-50%, intracranial response 42-67% and median progression-free survival 9.2-12.9 months. Randomized Phase III trial, ALTA-1 L is investigating brigatinib in ALK inhibitor-naive patients. PMID- 29451021 TI - The UVA/Padova Type 1 Diabetes Simulator Goes From Single Meal to Single Day. AB - BACKGROUND: A new version of the UVA/Padova Type 1 Diabetes (T1D) Simulator is presented which provides a more realistic testing scenario. The upgrades to the previous simulator, which was accepted by the Food and Drug Administration in 2013, are described. METHOD: Intraday variability of insulin sensitivity (SI) has been modeled, based on clinical T1D data, accounting for both intra- and intersubject variability of daily SI. Thus, time-varying distributions of both subject's basal insulin infusion and insulin-to-carbohydrate ratio were calculated and made available to the user. A model of "dawn" phenomenon based on clinical T1D data has been also included. Moreover, the model of subcutaneous insulin delivery has been updated with a recently developed model of commercially available fast-acting insulin analogs. Models of both intradermal and inhaled insulin pharmacokinetics have been included. Finally, new models of error affecting continuous glucose monitoring and self-monitoring of blood glucose devices have been added. RESULTS: One hundred in silico adults, adolescent, and children have been generated according to the above modifications. The new simulator reproduces the intraday glucose variability observed in clinical data, also describing the nocturnal glucose increase, and the simulated insulin profiles reflect real life data. CONCLUSIONS: The new modifications introduced in the T1D simulator allow to extend its domain of validity from "single-meal" to "single-day" scenarios, thus enabling a more realistic framework for in silico testing of advanced diabetes technologies including glucose sensors, new insulin molecules and artificial pancreas. PMID- 29451022 TI - Breast tomosynthesis for the clarification of mammographic BI-RADS 3 lesions can decrease follow-up examinations and enables immediate cancer diagnosis. AB - Background The limited sensitivity of mammography in case of a high breast density often produces unclear or false-positive findings, so-called BI-RADS 3 lesions, which have to be followed up to prove benignity. Digital breast tomosynthesis (DBT) was developed to reduce such summation effects. Purpose To evaluate the influence of an additional DBT on the management of mammographic BI RADS 3 findings and whether DBT can decrease the time to definitive diagnosis or not. Material and Methods We analyzed 87 patients with a mammographic non calcified BI-RADS 3 lesion who underwent an additional DBT of the affected breast. A follow-up two-dimensional (2D) examination or a histological result of the lesion had to be available. The images were analyzed especially for the BI RADS category and incremental diagnostic accuracy. Moreover, the inter-reader reliability and the radiation dose were evaluated. Results The BI-RADS category has been changed by the addition of DBT: 57.1% were assessed as BI-RADS 1 or 2, 4.6% as BI-RADS 4, and only 38.3% remained as BI-RADS 3. The intraclass correlation coefficient for the three readers showed a good agreement for inter reader reliability. No false-negative examination was found in the follow-ups. Nine lesions were biopsied (seven benign, two malignant). Both malignant lesions were suspicious in the DBT (BI-RADS 4). A significant higher glandular dose was necessary for the DBT. Conclusion DBT has the potential to reduce the recall-rate of BI-RADS 3 lesions and to find and diagnose malignant lesions earlier than 2D mammography alone. PMID- 29451023 TI - Mammographic screening attendance among immigrant and minority women: a systematic review and meta-analysis. AB - Background Groups of immigrant and minority women are more often diagnosed with advanced stage breast cancer than other women. Mammographic screening aims to reduce mortality from breast cancer through early detection in asymptomatic women. Purpose To compare mammographic screening attendance among immigrant and minority women to that of other women. Material and Methods A literature search of PubMed, Embase, Google Scholar, and Cochrane identified 1369 papers published between January 1995 and March 2016. In the review, we included 33 studies investigating mammographic screening attendance among immigrant and/or minority women. In a meta-analysis, we included 19 of the studies that compared attendance among immigrant and/or minority women with that among other women, using a random effects model. Results The review included studies from Europe, North America, and Oceania, with 42,666,093 observations of opportunities for mammographic screening. Attendance was generally lower among immigrant and minority women compared to other women (46.2% vs. 55.0%; odds ratio = 0.64, 95% confidence interval = 0.56-0.73; P < 0.05, I2 = 99.9%). Non-Western immigrants had lower attendance rates than other immigrants. Conclusion Immigrant and minority women had lower mammographic screening attendance than other women, which could potentially put them at increased risk for more advanced breast cancer. This review emphasizes the importance of continued efforts to engage with the preventative health needs of diverse populations in attempts to achieve equality in access to, and use of, care. PMID- 29451024 TI - Network pharmacology-based screening of the active ingredients and potential targets of the genus of Pithecellobium marthae (Britton & Killip) Niezgoda & Nevl for application to Alzheimer's disease. AB - Alzheimer's disease (AD) is a progressive neurodegenerative disorder associated with synaptic dysfunction, pathological accumulation of beta-amyloid (Abeta), and neuronal loss. Given the prevalence of AD and the lack of effective long-term therapies, there is a pressing need to discover viable leads that can be developed into clinically approved drugs with disease-modifying effects. The analysis of current reported literatures confirms the importance of the plants of Pithecellobium genus as candidate against AD. Hence, it is necessary to identify selective anti-dementia agents from this genus. To explore potential compounds with marked effect on AD in Pithecellobium genus, a compound database based on the methods of network pharmacology prediction was established in this paper by constructing the compound-disease target network. The result showed that the most effective compound in the plants of this genus might be (7'R,8'R)-7'-methoxyl strebluslignanol, and the most potential target might be Macrophage colony stimulating factor 1 receptor. PMID- 29451025 TI - Person-oriented research ethics: integrating relational and everyday ethics in research. AB - Research ethics is often understood by researchers primarily through the regulatory framework reflected in the research ethics review process. This regulatory understanding does not encompass the range of ethical considerations in research, notably those associated with the relational and everyday aspects of human subject research. In order to support researchers in their effort to adopt a broader lens, this article presents a "person-oriented research ethics" approach. Five practical guideposts of person-oriented research ethics are identified, as follows: (1) respect for holistic personhood; (2) acknowledgement of lived world; (3) individualization; (4) focus on researcher-participant relationships; and (5) empowerment in decision-making. These guideposts are defined and illustrated with respect to different aspects of the research process (e.g., research design, recruitment, data collection). The person-oriented research ethics approach provides a toolkit to individual researchers, research groups, and research institutions in both biomedical and social science research wishing to expand their commitment to ethics in research. PMID- 29451026 TI - The TiM system: developing a novel telehealth service to improve access to specialist care in motor neurone disease using user-centered design. AB - OBJECTIVES: Attendance at a specialist multidisciplinary motor neurone disease (MND) clinic is associated with improved survival and may also improve quality of life and reduce hospital admissions. However, patients struggle to travel to clinic and may experience difficulties between clinic visits that may not be addressed in a timely manner. We wanted to explore how we could improve access to specialist MND care. METHODS: We adopted an iterative, user-centered co-design approach, collaborating with those with experience of providing and receiving MND care including patients, carers, clinicians, and technology developers. We explored the unmet needs of those living with MND, how they might be met through service redesign and through the use of digital technologies. We developed a new digital solution and performed initial testing with potential users including clinicians, patients, and carers. RESULTS: We used these findings to develop a telehealth system (TiM) using an Android app into which patients and carers answer a series of questions about their condition on a weekly basis. The questions aim to capture all the physical, emotional, and social difficulties associated with MND. This information is immediately uploaded to the internet for review by the MND team. The data undergoes analysis in order to alert clinicians to any changes in a patient or carer's condition. CONCLUSIONS: We describe the benefits of developing a novel digitally enabled service underpinned by participatory design. Future trials must evaluate the feasibility and acceptability of the TiM system within a clinical environment. PMID- 29451027 TI - A case of late-onset OCD developing PLS and FTD. AB - We describe a 64-year-old woman, suffering from late-onset obsessive-compulsive disorder (OCD) from the age of 57, who developed dysarthria and dysphagia, spastic diplegic, and proximal muscles weakness. Needle electromyography showed no active denervation. Neuropsychological evaluation showed intact cognitive functioning. We diagnosed upper motor neuron disease (MND), with no known genetic correlates. Brain magnetic resonance (MRI) detected bilateral hippocampal atrophy with sclerosis of right hippocampus. 18F-FDG positron emission tomography (PET) showed moderate right temporal cortex thinning. Six months later, motor and behavioral symptoms worsened. Neuropsychological examination revealed long-term memory deficit and executive dysfunction. MRI and PET evidenced severe worsening of atrophy in temporal and frontal lobes. Four years later a definitive diagnosis of primary lateral sclerosis (PLS) and FTD was made. To our knowledge, this is the first report of PLS and FTD with OCD at onset. PMID- 29451028 TI - L'ethique du silence : le conflit d'interets explique-t-il le silence des employes? AB - Le silence des employes constitue une menace importante pour la reussite des organisations. Dans le present article, les auteurs avancent que le silence derive du conflit d'interets (CdI) structurel entre les employes et leur employeur. Cet argument repose sur la these egalement defendue dans l'article selon laquelle les leaders, qu'ils l'acceptent ou non, dependent de leurs employes pour obtenir de l'information fiable sur le travail effectue, car ceux ci connaissent intimement ce qu'ils font. La parole des employes devient donc une necessite organisationnelle. C'est egalement une realisation morale, car elle oblige l'individu a risquer ses interets personnels au profit de ceux de l'organisation. Les leaders doivent prendre des mesures pour attenuer les CdI et inciter les employes a s'exprimer. Le present article leur fournit plusieurs strategies en ce sens. PMID- 29451029 TI - Screening of ionic liquids for extraction of flavonoids from heather. AB - Room temperature ionic liquids are novel solvents with the specific properties that makes them of interest for application for extraction for a wide range of compounds. In this work extraction efficiency of flavonoids from heather flowers using ionic liquids based on imidazolium cation were evaluated and compared with organic solvents. It was found that the anion of ionic liquid significantly influence the extraction yields. Flavonoid content as well as antioxidant activity based on radical scavenging on 1,1-diphenul-2-pirylhydrazyl radicals and cupric reducing antioxidant capacity increased in the order: [Bmim]PF6 < [Bmim]BF4 < [Bmim]Cl. The obtained extraction yield using [Bmim]Cl were higher than reported for 60% ethanol and ethyl acetate under similar conditions, thus, may be helpful for better utilization of heather flowers as the potential pharmaceutical and nutraceutical ingredients.

AB - Despite condom use being the most protective measure against the transmission of human immunodeficiency virus (HIV), little is known about the intermediary relationships between condom negotiation, assertive sexual communication, and condom use efficacy. The purpose of the current study was to examine the relationships between these constructs within the context of an HIV prevention intervention. We examined two samples of African American college women participating in two HIV prevention interventions, one of which was based on social learning theory ( N = 214). Data collected at intervention posttest and 3 month follow-up were analyzed. Findings revealed that condom use efficacy at posttest fully mediated the relationship between intervention effect and assertive sexual communication at 3-month follow-up. In addition, condom use efficacy at posttest fully mediated the relationship between intervention effect and condom negotiation at 3-month follow-up. Implications of the importance of experiential learning, in combination with behavior observance, on the maintenance of condom protective behaviors are discussed. Findings have the potential to inform clinic and community-based HIV prevention interventions conducted among African American women. PMID- 29451033 TI - Control release of mitochondria-targeted antioxidant by injectable self assembling peptide hydrogel ameliorated persistent mitochondrial dysfunction and inflammation after acute kidney injury. AB - Persistent mitochondrial injury occurs after acute kidney injury (AKI) and mitochondria-targeted antioxidant Mito-2,2,6,6-tetramethylpiperidine-N-oxyl (TEMPO) (MT) has shown benefits for AKI, but its efficiency is limited by short half-life and side effect in vivo. Self-assembling peptide (SAP) hydrogel is a robust platform for drug delivery. This study aims to develop an SAP-based carrier to slow release MT for enhancing its long-term therapeutic potency on AKI. The KLD with aspartic acid (KLDD) was designed. The microstructure and in vitro release of MT was assayed. The protective role of MT-loaded SAP (SAP-MT) hydrogel on renal mitochondrial injury, tubular apoptosis, and inflammation was evaluated in mice at five days after ischemia-reperfusion injury (IRI). Our results showed that KLDD could self-assemble into cross-linked nanofiber hydrogel and it had lower release rate than free MT and KLD hydrogel. Compared to IRI and free MT mice, SAP-MT mice exerted reduced renal mitochondria-produced ROS (mtROS) and improved mitochondrial biogenesis and architecture. Consequently, SAP-MT mice showed less renal tubular cell apoptosis, kidney injury marker kidney injury molecule-1 (Kim-1) expression, lower level of pro-inflammatory factors expression, and macrophages infiltration than those of IRI and free MT mice. This study suggested that SAP-MT ameliorated IRI due to its extended mitochondrial protection role than free MT and thus improved the long-term outcomes of AKI. PMID- 29451034 TI - Cytochrome P450 in the central nervous system as a therapeutic target in neurodegenerative diseases. AB - Cytochromes P450 (CYPs) constitute a family of enzymes that can be found in the endoplasmic reticulum (ER), mitochondria or the cell surface of the cells. CYPs are characterized by carrying out the oxidation of organic compounds and they are mainly recognized as mediators of the biotransformation of xenobiotics to polar hydrophilic metabolites that can be eliminated from the organism. However, these enzymes play a key role in many other physiological processes, being involved in diverse indispensable metabolic pathways since they metabolize many endogenous substrates. Various CYP isoforms are expressed in the brain, and it is believed that this could be in part due to the particular function of brain CYPs. In the brain, CYPs are involved in the cholesterol turnover, the biosynthesis of dopamine, serotonin, morphine, hormones, and protective lipid mediators (epoxyeicosatrienoic acids), in addition to their already recognized role in xenobiotics detoxification and psychotropic drug metabolism. Increasing evidence suggests that this group of enzymes is fundamental for the normal functioning and maintenance of brain homeostasis. This review is focused on highlighting the importance of CYP-mediated endogenous metabolism in the central nervous system (CNS) and its relationship with recent findings regarding CYP involvement in neurodegenerative diseases. Some therapeutic approaches focused on CYP regulation are also discussed. PMID- 29451036 TI - Pharmaceutical-grade chondroitin sulfate in the management of knee osteoarthritis. AB - INTRODUCTION: Chondroitin Sulfate (CS) is a drug which is available as pharmaceutical-grade and nutriceutical-grade products, with important variations in preparation, composition, purity and therapeutic effects. Previous studies using pharmaceutical-grade CS suggested that the compound improves pain and function and delays structural progression in knee osteoarthritis (OA), whereas discrepant results were observed when lower grade preparations were investigated. Areas covered: The recently published chondroitin versus celecoxib versus Placebo Trial (CONCEPT) assessed the symptomatic effect of pharmaceutical-grade CS 800 mg/day in symptomatic knee OA. Expert opinion: This prospective, randomized, 6 month, 3-arm, double-blind, double-dummy, placebo and celecoxib (200 mg/day) - controlled trial involved 604 patients aged above 50 years with primary knee OA. This study showed that CS is superior to placebo and similar to celecoxib in reducing pain and improving function in Kellgren-Lawrence grade 1-3 patients supporting the role of pharmaceutical-grade CS as a potential first-line treatment for the management of patients with mild to moderate knee OA. PMID- 29451035 TI - Revisiting the physiological effects of methylene blue as a treatment of cyanide intoxication. AB - BACKGROUND: Although methylene blue (MB) had long been proposed to counteract the effects of cyanide (CN) intoxication, research on its mechanisms of action and efficacy has been abandoned for decades. Recent studies on the benefits of MB in post-anoxic injuries have prompted us to reexamine the relevance of this historical observation. METHODS: Our study was performed in adult male Sprague Dawley rats and on HEK293T epithelial cells. First, the effects and toxicity of MB (0-80 mg/kg) on circulation and metabolism were established in four urethane anesthetized rats. Then nine rats received a lethal infusion of a solution of KCN (0.75 mg/kg/min) and were treated by either saline or MB, at 20 mg/kg, a dose that we found to be innocuous in rat and to correspond to a dose of about 4 mg/kg in humans. MB was also administered 5 min after the end of a sub-lethal exposure to CN in a separate group of 10 rats. In addition, ATP/ADP ratio, ROS production, mitochondrial membrane potential (Deltapsim) and cellular O2 consumption rate (OCR) were determined in HEK293T cells exposed to toxic levels of CN (200 uM for 10 min) before and after applying a solution containing MB (1-100 uM for 10 min). RESULTS: Methylene blue was found to be innocuous up to 50 mg/kg. KCN infusion (0.75 mg/kg/min) killed all animals within 7-8 min. MB (20 mg/kg) administered at the same time restored blood pressure, cardiac contractility and limited O2 deficit, allowing all the animals to survive, without any significant methemoglobinemia. When administered 5 min after a non-lethal CN intoxication, MB sped up the recovery of lactate and O2 deficit. Finally, MB was able to decrease the production of ROS and restore the ATP/ADP ratio, Deltapsim as well as OCR of epithelial cells intoxicated by CN. CONCLUSIONS: The present observations should make us consider the potential interest of MB in the treatment of CN intoxication. The mechanisms of the antidotal properties of MB cannot be accounted for by the creation of a cyanomethemoglobinemia, rather its protective effects appears to be related to the unique properties of this redox dye, which, depending on the dose, could directly oppose some of the consequences of the metabolic depression produced by CN at the cellular level. PMID- 29451037 TI - Esophageal hiatal hernia: risk, diagnosis and management. AB - INTRODUCTION: Esophageal hiatal hernia involves abnormal abdominal entry into thoracic cavity. It is classified based on orientation between esophageal junction and diaphragm. Sliding hiatal hernia (Type-I) comprises the most frequent category, emanating from right crus of diaphragm. Type-II esophageal hernia engages both left and right muscular crura. Type-III and IV additionally include the left crus. Age and increased body mass index are key risk factors, and congenital skeletal aberrations trigger pathogenesis through intestinal malrotations. Familiar manifestations include gastric reflux, nausea, bloating, chest and epigastric discomfort, pharyngeal and esophageal expulsion and dysphagia. Weight loss and colorectal bleeding are severe symptoms. Areas covered: This review summarizes updated evidence of pathophysiology, risk factors, diagnosis and management of hiatal hernias. Laparoscopy and oesophagectomy procedures have been discussed as surgical procedures. Expert commentary: Endoscopy identifies untreatable gastric reflux; radiology is better for pre-operative assessments; manometry measures esophageal peristalsis, and CT scanning detects gastric volvulus and associated organ ruptures. Gastric reflux disease is mitigated using antacids and proton pump and histamine-2-receptor blockers. Severe abdominal penetration into chest cavity demands surgical approaches. Hence, esophagectomy has chances of post-operative morbidity, while minimally invasive laparoscopy entails fewer postoperative difficulties and better visualization of hernia and related vascular damages.

AB - Finasteride (FSD), a specific competitive inhibitor of the steroid type-II 5alpha reductase enzyme, is used in treatment of benign prostate hyperplasia (BPH) and male pattern baldness. The drug is of limited solubility that affect its dissolution and bioavailability. The aim was to study the effect of FSD particle size reduction on the pharmacokinetic, tissue distribution and cellular permeation. An optimized drug micro- and nano-particles were developed, characterized, administered to group of rats, and systemic pharmacokinetic and tissue distribution within target and not-target organs were determined using near-infrared (NIR) spectroscopy technique. Moreover, the cellular permeation of the prepared formulations through normal prostate epithelial cells was assessed and compared to pure FSD. The developed micro- and nano-particles were of 930 and 645 nm, respectively. Plasma maximum drug levels (Cmax) and overall exposure (AUC) of both formulations were not significantly higher than unformulated drug. However, micronized FSD achieved significant higher concentration within the target tissue (prostate) within the current study compared to pure drug and nano sized formulation as well. Yet, this is explained by the higher sequestration ability of spleen tissue to the nano-sized formula compared to micro-sized FSD. At the cellular level, permeation of nano-sized FSD through prostate epithelial cells was superior to the unformulated FSD as well as the micro-sized drug formulation. FSD particle size reduction significantly influences its cellular permeation and to a lesser extend affect its systemic pharmacokinetics and tissue distribution after oral administration.

AB - BACKGROUND: In South Asian countries like India, family system lays a strong foundation in societies and therefore, the context and consequences of single parent family structures are markedly different from that of the West. In these societies single parenthood is mainly an outcome of untimely death of any one of the parents. AIMS: This study tried to examine the influence of parents' survival status on the mental health of youth in India. METHODS: "Youth in India: situation and Needs (2006-2007)" survey data was used in the present study. We compared two groups of unmarried young population aged 15-24 y (n = 28 637): one having both parents alive and another having only one parent alive. Bivariate and multivariate techniques were applied to analyze the data. RESULTS: Results revealed that around 11% of the unmarried youth belonged to single parent families. Findings underscored a significant association between parent's survival and mental health of youth; respondents from single parent families were more likely to report metal health problems Moreover, effects of parents' survival were significant on females' mental health rather than males'. CONCLUSION: Policies must focus on reducing stress of young people growing up in single parent families through enhanced educational and employment opportunities.

AB - Administration of influenza vaccines to the lungs could be an attractive alternative to conventional parenteral administration. In this study, we investigated the deposition site of pulmonary delivered liquid and powder influenza vaccine formulations and its relation to their immunogenicity and protective efficacy. In vivo deposition studies in cotton rats revealed that, the powder formulation was mainly deposited in the trachea ( ~ 65%) whereas the liquid was homogenously distributed throughout the lungs ( ~ 96%). In addition, only 60% of the antigen in the powder formulation was deposited in the respiratory tract with respect to the liquid formulation. Immunogenicity studies showed that pulmonary delivered liquid and powder influenza formulations induced robust systemic and mucosal immune responses (significantly higher by liquids than by powders). When challenged with a clinical isolate of homologous H1N1pdm virus, all animals pulmonary administered with placebo had detectable virus in their lungs one day post challenge. In contrast, none of the vaccinated animals had detectable lung virus titers, except for two out of eight animals from the powder immunized group. Also, pulmonary vaccinated animals showed no or little signs of infection like increase in breathing frequency or weight loss upon challenge as compared to animals from the negative control group. In conclusion, immune responses induced by liquid formulation were significantly higher than responses induced by powder formulation, but the overall protective efficacy of both formulations was comparable. Thus, pulmonary immunization is capable of inducing protective immunity and the site of antigen deposition seems to be of minor relevance in inducing protection.

AB - INTRODUCTION: With the increase in multi-drug resistant P. aeruginosa, antimicrobials with a novel mechanism of action are needed that can target these infections. Areas covered: Intravenous murepavadin is in Phase 3 development for the treatment of HABP/VABP due to P. aeruginosa. This paper summarizes the available information on the discovery, the in vitro activity, pharmacokinetic and pharmacodynamic properties and the clinical pharmacology of murepavadin to date. Expert commentary: P. aeruginosa has an intrinsic resistance to many antibiotics due to high cellular impermeability and efficient drug efflux mechanisms, and the recent increase in prevalence of multidrug-resistant P. aeruginosa infections are particularly threatening in ICU settings. Murepavadin is a pathogen specific antimicrobial peptidomimetic with a novel, non-lytic mechanism of action, and is the first in class of outer membrane protein targeting antibiotics which are being developed. Murepavadin displays a potent in vitro activity including carbapenemase-producing and colistin-resistant P. aeruginosa. Murepavadin is active in pre-clinical animal models including infections with XDR isolates. The Pharmacokinetics is well characterized including subjects with impaired renal function and patients with VABP. Intravenous murepavadin is currently under clinical development for the treatment of HABP/VABP due to P. aeruginosa infection.

AB - Being the largest archipelago country in the world, with a tropical climate and a unique flora and fauna, Indonesia habitats one of the most diverse biome in the world. These characteristics make Indonesia a popular travel destination, with tourism numbers increasing yearly. These characteristics also facilitate the transmission of zoonosis and provide ideal living and breading circumstances for arthropods, known vectors for viral diseases. A review of the past 10 years of literature, reports of the Ministry of Health, Republic of Indonesia and ProMED mail shows a significant increase in dengue infection incidence. Furthermore, chikungunya, Japanese encephalitis and rabies are proven to be endemic in Indonesia. The combination of cohort studies, governmental data and ProMED-mail reveals an integrated overview for those working in travel medicine and public health, focusing on both endemic and emerging acute virus infections. This review summarizes the epidemiology of acute virus infections in Indonesia, including outbreak reports, as well as public health response measurements and their potential or efficacy. Knowledge about human behaviour, animal reservoirs, climate factors, environment and their role in emerging virus infection are discussed. We aim to support public health authorities and health care policy makers in a One Health approach. PMID- 29451045 TI - Modified release paracetamol overdose: a prospective observational study (ATOM 3). AB - BACKGROUND: Modified-release (MR) paracetamol is available in many countries as 665 mg tablets of which 69% is MR and 31% is immediate release. There are concerns that MR paracetamol overdose has higher rates of liver injury despite standard treatment algorithms. The objective of this study was to describe the clinical characteristics and outcomes of acute MR paracetamol overdose. METHODS: Prospective observational study, recruiting patients from January 2013 to June 2017, from five clinical toxicology units and calls to two Poisons Information Centres in Australia. Included were patients >14 years who ingested >=10 g or 200 mg/kg (whichever is less) of MR paracetamol. Data collected included demographics, ingestion history, pathology results, treatments, and outcomes including hepatotoxicity (ALT >1000 U/L). RESULTS: In total, 116 patients were recruited, 85(73%) were female. The median dose ingested was 32 g (IQR: 20-49 g) and median time to presentation was 3 h (IQR: 2-9 h). 78(67%) had an initial paracetamol concentration above the nomogram line (150 mg/L at 4 h). A further 12(10%) crossed the nomogram after repeat paracetamol measurements, of which five crossed after two non-toxic levels 4 h apart. Six had a double paracetamol peak, in three occurring >24 h post-ingestion. 113(97%) received acetylcysteine of which 67 received prolonged treatment beyond the standard 21 h. This was because of an elevated paracetamol concentration at the completion of acetylcysteine in 39 (median paracetamol concentration 25 mg/L, IQR: 16-62 mg/L). 21 (18%) developed hepatotoxicity, including six treated within 8 h of ingestion. Activated charcoal and double doses of acetylcysteine did not significantly decrease the risk of hepatotoxicity. CONCLUSIONS: Drug regulatory authorities are considering restrictions on MR paracetamol preparations. Following an acute MR paracetamol overdose, this study found that many patients had a persistently elevated paracetamol concentrations, many required prolonged treatment and some developed liver injury despite early acetylcysteine treatment. Furthermore, activated charcoal and increased acetylcysteine did not appear to significantly alter the risk of liver injury. Hence, research into better treatment strategies is required.

PMID- 29451047 TI - National survey of Japanese patients with mevalonate kinase deficiency reveals distinctive genetic and clinical characteristics. AB - OBJECTIVES: Mevalonate kinase deficiency (MKD), a rare autosomal recessive autoinflammatory syndrome, is caused by disease-causing variants of the mevalonate kinase (MVK) gene. A national survey was undertaken to investigate clinical and genetic features of MKD patients in Japan. METHODS: The survey identified ten patients with MKD. Clinical information and laboratory data were collected from medical records and by direct interviews with patients, their families, and their attending physicians. Genetic analysis and measurement of MVK activity and urinary excretion of mevalonic acid were performed. RESULTS: None of the 10 patients harbored MVK disease-causing variants that are common in European patients. However, overall symptoms were in line with previous European reports. Continuous fever was observed in half of the patients. Elevated transaminase was observed in four of the 10 patients, two of whom fulfilled the diagnostic criteria for hemophagocytic lymphohistiocytosis. About half of the patients responded to temporary administration of glucocorticoids and NSAIDs; the others required biologics such as anti-IL-1 drugs. CONCLUSION: This is the first national survey of MKD patients in a non-European country. Although clinical symptoms were similar to those reported in Europe, the incidence of continuous fever and elevated transaminase was higher, probably due to differences in disease-causing variants. PMID- 29451048 TI - Impact of radon and combinatory radon/carbon dioxide spa on pain and hypertension: Results from the explorative RAD-ON01 study. AB - OBJECTIVES: Therapies with low doses of radon have beneficial effects on patients suffering from chronic painful degenerative and inflammatory diseases. We already showed that this is accompanied by systemic immune modulations. We here focus on pain-reducing effects of very low doses of radon by adding carbon dioxide water and its impact on heart rate variability (HRV), blood pressure and free radicals. METHODS: 97 of 103 patients receiving radon spa (1.200 Bq/l at 34 degrees C or 600 Bq/l, 1 g/l CO2 at 34 degrees C) were monitored before and at three different time points after therapy. Individual pain perception was analyzed and the capability to process radicals. At each time point, the hypertensive patients (n = 46) were examined over 24 h for blood pressure and HRV. RESULTS: Long-term pain reduction was observed in the majority of patients. A modulation of superoxide dismutase was identified, presumably representing a priming effect for lowering radiation stress. Further, lowering of blood pressure, especially in those patients who additionally received carbon dioxide, was seen. Radon did in particular impact on HRV implying lasting relaxation effects. CONCLUSION: Radon/carbon dioxide spa efficiently reduces pain. In particular, patients simultaneously suffering from painful and cardiovascular diseases should be treated by combination of radon and CO2. PMID- 29451049 TI - The increase in bone mineral density by bisphosphonate with active vitamin D analog is associated with the serum calcium level within the reference interval in postmenopausal osteoporosis. AB - OBJECTIVES: To examine the factors associated with increase in lumbar spine bone mineral density (LS-BMD) by bisphosphonates (BPs) with active vitamin D analog (aVD). METHODS: Two independent postmenopausal osteoporotic patients treated by BPs with aVD for 24 months (Study 1: n = 93, Study 2: n = 99) were retrospectively analyzed. RESULTS: In Study 1, LS-BMD of the patients significantly increased for 24 m (5.4%, p < .001). A multiple regression analysis among baseline characteristics revealed that serum calcium (sCa: 8.5-10.5 mg/dL) was associated with an increased LS-BMD by treatment (r2: 0.088, p = .02). While average sCa of the patients was 9.2 mg/dL before treatment, it increased time dependently to 9.6 mg/dL for 24 m by treatment. As each patient had their LS-BMD five times during the study, there were four instances of %LS-BMD in each patient, resulting in 372 instances of %LS-BMD in Study 1. The smallest Akaike's information criterion value for the most appropriate cut-off levels of sCa for %LS-BMD by treatment every 6 m was 9.3 mg/dL. The %LS-BMD by treatment for 6 m during 24 m period in patients with sCa >=9.3 mg/dL (1.5%) was significantly higher than that in patients with sCa <9.3 mg/dL (0.8%, p = .038). The results of Study 2 were similar to those of Study 1, confirming the phenomena observed. CONCLUSION: sCa was associated with an increased LS-BMD by BPs with aVD. PMID- 29451050 TI - 9 years' follow-up of 168 pin-fixed supracondylar humerus fractures in children. AB - Background and purpose - The long-term outcome of pin-fixed supracondylar humerus fractures (SCHF) in children is not well known. We assessed the 7- to 12-year outcome in 168 children. Patients and methods - During 2002-2006, 210 domestic children (age 7 (1-14) years) with SCHF (Gartland III 79%, Gartland II 19%, and flexion type 2%) were pin fixed in Helsinki. 36 (17%) patients had a nerve palsy. Radiographic alignment was regarded as satisfactory in 81% of patients (Baumann angle (BA) within +/-10 of normal range and whose anterior humeral line (AHL) crossed the capitulum). After a mean follow-up of 9 (7-12) years, 168 (80%) patients answered a questionnaire regarding elbow appearance (scale 0-10), function (scale 0-10), and pain (scale 0-10), and symmetry of range of motion (ROM) and carrying angle (CA). 65 (31%) patients also attended a clinical follow up examination. Results - Mean subjective score for appearance was 8.7 (2-10) and for function 9.0 (2-10) (n = 168). Elbow ROM asymmetry was experienced by 28% and elbow CA asymmetry by 17% of the patients. Elbow pain was reported by 14%, and was more common in children with nerve injuries. Long-term outcome was good or excellent in 60/65 and CA in 56/65 of the follow-up visit patients using Flynn's criteria. BA exceeding normal values by 10 was associated with lower subjective outcome; AHL crossing point with the capitulum was not associated with outcome. Interpretation - Long-term subjective outcome is satisfactory with few exceptions if elbow ROM and CA are restored within 10 degrees of the uninjured elbow. Radiographs at fracture union have little prognostic value. Nerve injuries can cause long-term pain. PMID- 29451051 TI - Influence of surgical approach on complication risk in primary total hip arthroplasty. AB - Background and purpose - Systematic comparisons of anterior approach (A) versus posterior approach (P) in primary total hip arthroplasty (THA) have largely focused on perioperative outcomes. In this systematic review with meta-analysis, we compared complication risk of A versus P in studies of primary THA with at least 1-year mean follow-up. Patients and methods - We performed a systematic review of prospective and retrospective studies with at least 1-year mean follow up that reported complications of A and P primary THA. Complications included infection, dislocation, reoperation, thromboembolic event, heterotopic ossification, wound complication, fracture, and nerve injury. Random effects meta analysis was used for all outcomes. Complication risk was reported as rate ratio (RR) to account for differential follow-up durations; values >1 indicated higher complication risk with A and values <1 indicated lower risk with A. Results - 19 studies were included; 15 single-center comparative studies with 6,620 patients (2,278 A; 4,342 P) and 4 multicenter registries with 157,687 patients (18,735 A; 138,952 P). Median follow-up was 16 (12-64) months) with A and 18 (12-110) months with P. Anterior approach was associated with lower rate of infection (RR =0.55, p = 0.002), dislocation (RR =0.65, p = 0.03), and reoperation (RR =0.84, p < 0.001). No statistically significant differences were observed in rate of thromboembolic event (RR =0.59, p = 0.5), heterotopic ossification (RR =0.63, p = 0.1), wound complication (RR =0.93, p = 0.8), or fracture (RR =1.0, p = 0.9). There was a higher rate of patient-reported nerve injury with A (RR =2.3, p = 0.01). Interpretation - Comparing A with P in primary THA, A was associated with lower risk of reoperation, dislocation, and infection, but higher risk of patient reported nerve injury.

AB - The physicochemical properties of silver nanoparticles (AgNPs) in human whole saliva are investigated herein. In authentic saliva samples, AgNPs exhibit a great stability with over 70% of the nanomaterial remaining intact after a 24-h incubation in the presence of ~0.3 mM dissolved oxygen. The small loss of AgNPs from the saliva sample has been demonstrated to be a result of two processes: agglomeration/aggregation (not involving oxygen) and oxidative dissolution of AgNPs (assisted by oxygen). In authentic saliva, AgNPs are also shown to be more inert both chemically (silver oxidative dissolution) and electrochemically (electron transfer at an electrode) than in synthetic saliva or aqueous electrolytes. The results thus predict based on the chemical persistence (over a 24-h study) of AgNPs in saliva and hence the minimal release of hazardous Ag+ and reactive oxygen species that the AgNPs are less likely to cause serious harm to the oral cavity but this persistence may enable their transport to other environments.

PMID- 29451055 TI - Early discontinuation of empirical antibacterial therapy in febrile neutropenia: the ANTIBIOSTOP study. AB - INTRODUCTION: Immediate empirical antibiotic therapy is mandatory in febrile chemotherapy-induced neutropenia, but its optimal duration is unclear, especially in patients with fever of unknown origin (FUO). OBJECTIVES: The primary objective of this 20-month prospective observational study was to evaluate the feasibility and safety of short-term antibiotic treatment in afebrile or febrile patients exhibiting FUO, irrespective of their neutrophil count. The secondary objective was to describe the epidemiology of all episodes of febrile neutropenia. METHODS: In the first phase of the study, empirical antibiotic therapy in FUO patients was stopped after 48 h of apyrexia, in accordance with European Conference on Infections in Leukaemia guidelines (n = 45). In the second phase of the study, antibiotics were stopped no later than day 5 for all FUO patients, regardless of body temperature or leukocyte count (n = 37). RESULTS: Two hundred and thirty eight cases of febrile neutropenia in 123 patients were included. Neither the composite endpoint (p = .11), nor each component (in-hospital mortality (p = .80), intensive care unit admission (p = 0.48), relapse of infection <=48 h after discontinuation of antibiotics (p = .82)) differed between the two FUO groups. Violation of protocol occurred in 17/82 episodes of FUO without any major impact on statistical results. Twenty-six (57.3%) and 22 (59.5%) FUO episodes did not relapse during hospital-stay (p = 1), and nine (20%) and five (13.5%) presented another FUO, respectively. One hundred and fifty-six episodes of febrile neutropenia (65.5%) were clinically or microbiologically documented, including 85 bacteremia. CONCLUSIONS: These results suggest that early discontinuation of empirical antibiotics in FUO is safe for afebrile neutropenic patients. PMID- 29451056 TI - Epidemiology of injuries in Portuguese senior male rugby union sevens: a cohort prospective study. AB - OBJECTIVES: To assess the incidence, type and location of injuries sustained during the Portuguese rugby union sevens circuit. To investigate the influence of players' training loads on injury risk. METHODS: A prospective cohort study recording time-loss injuries was conducted with all teams competing in the Portuguese national rugby sevens circuit (eight from the top-tier and seven from the second-tier). Main outcome measures included: incidence rate, anatomical location, type, injury incident and severity. Data were also collected regarding players' training loads. Fisher's exact test was used to estimate the relative risk of suffering an injury during the sevens season and training sevens during the fifteens season. RESULTS: A total of 27 injuries were recorded corresponding to an incidence rate of 133.9 injuries per 1000 player match-hours. The average severity was 22.22 days. Contact events preceded 81.5% of injuries. Most injuries occurred in the lower limb (66.7%) and were joint/ligament or muscle/tendon injuries (85.1%). The association between injuries and lower volume of training during the sevens season was identified for the second-tier (p = 0.021). For the same level, an inverse relation between training hours and injury severity was also found (p = 0.008). Top-tier players training sevens and fifteens simultaneously during the year presented a significant increase of injury risk (relative risk = 3.2; p = 0.011). CONCLUSIONS: Injury incidence in our study is similar to that reported for international sevens, although severity is lower. An association between training loads and the occurrence of injuries was found for both tiers, although with differential results, thus reinforcing the need to customize players' preparation. Further studies at non-elite competitions are needed to gather significant data to accurately formulate future injury prevention protocols or recommend modifications to game laws or competition formats, aiming at players' welfare. PMID- 29451057 TI - Comparison between modified Dunn procedure and in situ fixation for severe stable slipped capital femoral epiphysis. AB - Background and purpose - The best treatment option for severe slipped capital femoral epiphysis (SCFE) is still controversial. We compared clinical and radiographic outcomes of modified Dunn procedure (D) and in situ fixation (S) in severe SCFE. Patients and methods - We retrospectively compared D and S, used for severe stable SCFE (posterior sloping angle (PSA) > 50 degrees ) in 29 patients (15 D; 14 S). Propensity analysis and inverse probability of treatment weights (IPTW) to adjust for baseline differences were performed. Patients were followed for 2-7 years. Results - Avascular necrosis (AVN) occurred in 3 patients out of 15, after D, causing conversion to total hip replacement (THR) in 2 cases. In S, 1 hip developed chondrolysis, requiring THR 3 years after surgery. 3 symptomatic femoroacetabular impingements (FAI) occurred after S, requiring corrective osteotomy in 1 hip, and osteochondroplasty in another case. The risk of early re operation was similar between the groups. The slippage was corrected more accurately and reliably by D. The Nonarthritic Hip Score was similar between groups, after adjusting for preoperative and postoperative variables. Interpretation - Although D was superior to S in restoring the proximal femoral anatomy, without increasing the risk of early re-operation, some concern remains regarding the potential risk of AVN in group D. PMID- 29451058 TI - Developmental differences in stress responding after repeated underwater trauma exposures in rats. AB - Adolescence is a distinct developmental period characterized by behavioral and physiological maturation. Rapid ongoing changes during neurodevelopment in particular present potential opportunities for stress to have lasting effects on longitudinal outcomes of behavioral and neuroendocrine function. While adult stress effects on outcomes during adulthood have been characterized, little is known about the lasting effects of adolescent repeated stressor exposure on outcomes during adolescence. We have previously reported different stress responses in adolescent rats relative to adult rats, including a blunted fear response outcome in adulthood in rats stressed during adolescence. The present study characterized the ontogeny of behavioral and neuroendocrine responses to eight underwater trauma (UWT) exposures in rats over a two week poststress time period during adolescence (P34) or adulthood (P83) relative to age-matched control groups that underwent eight swimming episodes without UWT. Repeated UWT exposures starting in adolescence, but not adulthood, resulted in adverse behavioral responses on the elevated plus maze 1 day post-stress. Corticosterone responses did not differ between UWT-exposed and controls for either age group at 1 day or at 7 days poststress, although there was an effect of age on corticosterone levels. We conclude that repeated UWT stress events have a lasting, negative behavioral effect on adolescent rats that is not observed in adult rats after the two-week exposure window. These results suggest that neurophysiological mechanisms underlying recovery from a repeated stressor are immature in adolescence relative to adulthood in rats. PMID- 29451059 TI - 'Oncokompas', a web-based self-management application to support patient activation and optimal supportive care: a feasibility study among breast cancer survivors. AB - BACKGROUND: Cancer survivors have to deal with symptoms related to cancer and its treatment. In Oncokompas, cancer survivors monitor their quality of life by completing patient reported outcome measures (PROMs), followed by personalized feedback, self-care advice, and supportive care options to stimulate patient activation. The aim of this study was to investigate feasibility and pretest posttest differences of Oncokompas including a newly developed breast cancer (BC) module among BC survivors. MATERIAL AND METHODS: A pretest-posttest design was used. Feasibility was investigated by means of adoption, usage, and satisfaction rates. Several socio-demographic and clinical factors, and health-related quality of life (HRQOL) were explored that might be associated with patient satisfaction. Barriers and facilitators of Oncokompas feasibility were investigated by evaluating nurse consultation reports. Differences in patient activation (Patient Activation Measure) and patient-physician interaction (Perceived Efficacy in Patient-Physician Interactions) before and after Oncokompas use were investigated. RESULTS: In total, 101 BC survivors participated. Oncokompas had an adoption rate of 75%, a usage rate of 75-84%, a mean satisfaction score of 6.9 (range 0-10) and a Net Promoter Score (NPS) of -36 (range -100-100) (N = 68). The BC module had a mean satisfaction score of 7.6. BC survivors who received surgery including chemotherapy and/or radiotherapy were significantly more satisfied with Oncokompas than BC survivors with surgery alone (p = .013). Six facilitators and 10 barriers of Oncokompas feasibility were identified. After using Oncokompas, BC survivors scored significantly higher on patient activation (p = .007; r = .24), but not on patient-physician interaction (p = .75). CONCLUSION: Oncokompas including a BC module is considered feasible, but needs further optimization to increase user satisfaction. This study shows the value of tailoring eHealth applications for cancer survivors to their specific tumor type. Oncokompas including the BC module seems to improve patient activation among BC survivors. PMID- 29451061 TI - Neck-Tongue Syndrome: An Underrecognized Childhood Onset Cephalalgia. AB - Neck-tongue syndrome is a rarely reported headache disorder characterized by occipital and/or upper neck pain triggered by sudden rotatory head movement and accompanied by abnormal sensation and/or posture of the ipsilateral tongue. Although onset is thought to be in childhood, most of the limited number of cases reported so far were adults. Here the authors describe 3 cases, 2 girls and 1 boy, with neck-tongue syndrome. In each child additional headache symptoms occurred, headache improved over time in all, spontaneously in 2 and coinciding with gabapentin treatment in the other. Investigations were consistently unremarkable. Review of the literature reveals a usually self-limiting disorder, with early onset and variable additional features. Awareness of neck-tongue syndrome among pediatric neurologists and other practitioners is important, to allow for timely diagnosis and informed management of an underreported headache disorder with childhood onset. PMID- 29451060 TI - Cord blood buffy coat DNA methylation is comparable to whole cord blood methylation. AB - Cord blood DNA methylation is associated with numerous health outcomes and environmental exposures. Whole cord blood DNA reflects all nucleated blood cell types, while centrifuging whole blood separates red blood cells, generating a white blood cell buffy coat. Both sample types are used in DNA methylation studies. Cell types have unique methylation patterns and processing can impact cell distributions, which may influence comparability. We evaluated differences in cell composition and DNA methylation between cord blood buffy coat and whole cord blood samples. Cord blood DNA methylation was measured with the Infinium EPIC BeadChip (Illumina) in eight individuals, each contributing buffy coat and whole blood samples. We analyzed principal components (PC) of methylation, performed hierarchical clustering, and computed correlations of mean-centered methylation between pairs. We conducted moderated t-tests on single sites and estimated cell composition. DNA methylation PCs were associated with individual (PPC1 = 1.4 * 10-9; PPC2 = 2.9 * 10-5; PPC3 = 3.8 * 10-5; PPC4 = 4.2 * 10-6; PPC5 = 9.9 * 10-13, PPC6 = 1.3 * 10-11) and not with sample type (PPC1-6>0.7). Samples hierarchically clustered by individual. Pearson correlations of mean-centered methylation between paired samples ranged from r = 0.66 to r = 0.87. No individual site significantly differed between buffy coat and whole cord blood when adjusting for multiple comparisons (five sites had unadjusted P<10-5). Estimated cell type proportions did not differ by sample type (P = 0.46), and estimated proportions were highly correlated between paired samples (r = 0.99). Differences in methylation and cell composition between buffy coat and whole cord blood are much lower than inter-individual variation, demonstrating that both sample preparation types can be analytically combined and compared. PMID- 29451062 TI - Exploratory rearing: a context- and stress-sensitive behavior recorded in the open-field test. AB - Stressful experiences are linked to anxiety disorders in humans. Similar effects are observed in rodent models, where anxiety is often measured in classic conflict tests such as the open-field test. Spontaneous rearing behavior, in which rodents stand on their hind legs to explore, can also be observed in this test yet is often ignored. We define two forms of rearing, supported rearing (in which the animal rears against the walls of the arena) and unsupported rearing (in which the animal rears without contacting the walls of the arena). Using an automated open-field test, we show that both rearing behaviors appear to be strongly context dependent and show clear sex differences, with females rearing less than males. We show that unsupported rearing is sensitive to acute stress, and is reduced under more averse testing conditions. Repeated testing and handling procedures lead to changes in several parameters over varying test sessions, yet unsupported rearing appears to be rather stable within a given animal. Rearing behaviors could therefore provide an additional measure of anxiety in rodents relevant for behavioral studies, as they appear to be highly sensitive to context and may be used in repeated testing designs. PMID- 29451063 TI - Epithelial tumors: Growing from within. AB - The growth of epithelial tumors is often governed by cell interactions with the surrounding stroma. Drosophila has been instrumental in identifying the relevant molecular elements mediating these interactions. Of note is the role of the TNF ligand Eiger, released from recruited blood cells, in activating the JNK tumor promoting pathway in epithelial tumors. JNK drives the transcriptional induction of mitogenic molecules, matrix metalloproteases and systemic signals that lead to tumor growth, tissue invasiveness and malignancy. Here we review our findings on a tumor-intrinsic, Eiger- and stroma-independent mechanism that contributes to the unlimited growth potential of tumors caused either by chromosomal instability or impaired cell polarity. This newly identified mechanism, which was revealed in an experimental condition in which contacts between tumor cells and wild-type epithelial cells were minimized, relies on interactions between functionally distinct tumor cell populations that activate JNK in a cell-autonomous manner. We discuss the impact of cell interaction-based feedback amplification loops on the unlimited growth potential of epithelial tumors. These findings are expected to contribute to the identification of the relevant cell populations and molecular mechanisms to be targeted in drug therapy. PMID- 29451064 TI - Inactivation gating of Kv7.1 channels does not involve concerted cooperative subunit interactions. AB - Inactivation is an intrinsic property of numerous voltage-gated K+ (Kv) channels and can occur by N-type or/and C-type mechanisms. N-type inactivation is a fast, voltage independent process, coupled to activation, with each inactivation particle of a tetrameric channel acting independently. In N-type inactivation, a single inactivation particle is necessary and sufficient to occlude the pore. C type inactivation is a slower process, involving the outermost region of the pore and is mediated by a concerted, highly cooperative interaction between all four subunits. Inactivation of Kv7.1 channels does not exhibit the hallmarks of N- and C-type inactivation. Inactivation of WT Kv7.1 channels can be revealed by hooked tail currents that reflects the recovery from a fast and voltage-independent inactivation process. However, several Kv7.1 mutants such as the pore mutant L273F generate an additional voltage-dependent slow inactivation. The subunit interactions during this slow inactivation gating remain unexplored. The goal of the present study was to study the nature of subunit interactions along Kv7.1 inactivation gating, using concatenated tetrameric Kv7.1 channel and introducing sequentially into each of the four subunits the slow inactivating pore mutation L273F. Incorporating an incremental number of inactivating mutant subunits did not affect the inactivation kinetics but slowed down the recovery kinetics from inactivation. Results indicate that Kv7.1 inactivation gating is not compatible with a concerted cooperative process. Instead, adding an inactivating subunit L273F into the Kv7.1 tetramer incrementally stabilizes the inactivated state, which suggests that like for activation gating, Kv7.1 slow inactivation gating is not a concerted process. PMID- 29451066 TI - Psychometric properties of MDHAQ/RAPID3 in patients with systemic lupus erythematosus. AB - Background The Multidimensional Health Assessment Questionnaire (MDHAQ) is a patient-reported outcome (PRO) tool that includes the Routine Assessment of Patient Index Data 3 (RAPID3), an index that can be calculated at the point of care. The objective of this study was to perform psychometric analyses of MDHAQ/RAPID3 to study its measurement properties in systemic lupus erythematosus (SLE). Methods The MDHAQ was completed by 161 SLE patients in routine care, along with LupusPRO (a disease-specific PRO). The SLE disease-specific activity index (SELENA-SLEDAI) and damage (SDI) were assessed. Data from 70 patients with rheumatoid arthritis who had completed MDHAQ during their routine medical care were used as controls to compare the results of Physical Function (FN) domain exploratory factor analysis. Internal consistency reliability (ICR) for FN items was calculated using Cronbach's alpha. Validity of MDHAQ/RAPID3 was evaluated for content validity and construct validity. Responsiveness of the RAPID3 to changes in disease activity anchors was assessed. Results The ICR of the 10 physical function items on Cronbach's alpha was 0.88. Exploratory factor analysis revealed cross-loadings of three FN items. RAPID3 showed a strong correlation with LupusPRO health-related quality of life score (rho -0.68 ( p < 0.001)), indicating convergent validity. RAPID3 scores did not correlate with disease activity indices or SDI. After adjustment for fibromyalgia status, a weak correlation with the Physician's Global Assessment (PGA) (rho = 0.31, p = 0.008) was noted. RAPID3 could differentiate between SLE patients based on flare status. RAPID3 was not responsive to changes in PGA, SELENA-SLEDAI or SELENA-Flare Index. Conclusions MDHAQ/RAPID3 has fair reliability and validity in SLE. PMID- 29451065 TI - Shoulder and arm muscle activity during elastic band exercises performed in a hospital bed. AB - OBJECTIVE: Muscle atrophy is a common side-effect of bed rest during hospitalization. However, resistance training may minimize or even prevent these complications. Therefore, we evaluated the efficiency of four upper-body elastic resistance exercises that could be performed while lying or sitting in a hospital bed. METHODS: Twenty-two healthy subjects performed three repetitions of each exercise in a supine and seated position with a perceived intensity of 3 (low) and 8 (high) on the Borg CR10 Scale. Surface electromyography was collected from 12 shoulder and arm muscles (e.g. trapezius, deltoideus, and biceps brachii), and normalized to a maximal voluntary isometric contraction (nEMG). RESULTS: During all exercises performed at high intensity, moderate (>40%) to high (>60%) levels of nEMG were found for the majority of the analysed muscles, e.g. deltoideus (from 37% to 69%, median 57.5%), trapezius (from 43% to 66%, median 51%), and infraspinatus (from 54% to 66%, median 59%), with the exception of pectoralis major (from 29% to 47%, median 39.5%) and latissimus dorsi (from 15% to 22%, median 18.5%). No significant differences were found between the supine and seated positions for any of the exercises. CONCLUSION: This study showed that high levels of shoulder and arm muscle activity can be achieved while lying or sitting in a hospital bed using appropriate exercises with elastic bands. The data presented here can be used by physiotherapists as a guideline for selecting suitable and effective strengthening exercises during in-hospital rehabilitation to counteract bed-rest related muscle atrophy in the upper body. PMID- 29451067 TI - Combined detection of uMCP-1 and uTWEAK for rapid discrimination of severe lupus nephritis. AB - Reliable markers for the rapid discrimination of severe renal damage remain a vital concern for lupus nephritis (LN). To determine a better tool for kidney damage detection, the present study compared the evaluation ability of novel urinary cytokines and chemokines (namely urinary monocyte chemoattractant protein 1 (uMCP-1), tumor necrosis factor-like weak inducer of apoptosis (uTWEAK)) with traditional serum or urinary markers (namely urinary alpha 1-microgrobulin (ualpha1-MG), beta 2-microglobulin (ubeta2-MG) and serum complement C3 (C3), complement C4 (C4), creatinine (Cr), blood urea nitrogen (BUN) and cystatin C (Cys C)) in discriminating LN renal damage. Correlations between markers with Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) renal SLEDAI scores, biopsy activity index (BAI) and biopsy chronicity index (BCI) scores were evaluated. Receiver operating characteristic (ROC) curves were generated to evaluate a single or combined model in discriminating active renal involvement (rSLEDAI scores > 0) and patients with poor pathological outcome (BAI scores >= 7). uMCP-1 and uTWEAK possess higher correlation coefficients with renal damage and larger areas under ROC curves (AUCs) than other markers. A combined model of uMCP-1 and uTWEAK showed an AUC of 0.887, sensitivity of 86.67% and specificity of 80.00% to discriminate active LN, and an AUC of 0.778, sensitivity of 75.00% and specificity of 81.82% to discriminate LN with poor outcome, which are better than the utility of any markers individually. PMID- 29451068 TI - Increased visceral adipose tissue and altered adiposity distribution in premenopausal lupus patients: correlation with cardiovascular risk factors. AB - Objective Visceral adipose tissue (VAT) correlates with cardiovascular risk factors and has never been assessed in systemic lupus erythematosus (SLE). Our aim was to evaluate VAT in premenopausal SLE patients. Methods Sixty-three premenopausal SLE patients and 186 age-matched healthy women were included. Demographic, anthropometric, disease and treatment parameters were evaluated. VAT was measured by dual X-ray absorptiometry (DXA) with APEX 4.0 software. Results SLE patients had a disease duration of 5.25 +/- 3.80 years, SLEDAI activity score of 4.35 +/- 5.13, SLICC/ACR-DI of 0.70 +/- 0.80, current prednisone dose of 11.60 +/- 12.10 mg/day and cumulative glucocorticoid dose of 22.34 +/- 12.94 g. Overweight/obese SLE patients and controls had similar VAT parameters ( p > 0.05). Among individuals with BMI <25 kg/m2, SLE patients and controls had similar weight, fat mass and fat percentage ( p > 0.05) but patients had higher values of VAT parameters (VAT mass: 260.60 +/- 117.23 vs. 194.77 +/- 71.42 g, p = 0.001; VAT area: 54.05 +/- 24.30 vs. 40.40 +/- 14.82 cm2, p = 0.001; VAT volume: 281.75 +/- 126.81 vs. 210.61 +/- 77.29 cm3, p = 0.001) and trunk/limb fat mass ratio (0.78 +/- 0.21 vs. 0.67 +/- 0.12, p = 0.002) compared to controls. In SLE, VAT area correlated with weight ( r = 0.66, p < 0.001), non-HDL cholesterol ( r = 0.53, p < 0.001), LDL cholesterol ( r = 0.48, p < 0.001) and triglycerides ( r = 0.33, p = 0.008), but not with disease duration, SLEDAI, SLICC/ACR-DI or current glucocorticoid use ( p > 0.05). Conclusion This study provides original evidence that SLE is associated with increased VAT and altered adiposity distribution. The correlation with traditional risk factors for cardiovascular disease, independent of current glucocorticoid dose and disease activity, suggests the role of visceral fat as an additional tool for risk assessment in these young patients. PMID- 29451069 TI - Arthritis and use of hydroxychloroquine associated with a decreased risk of macrophage activation syndrome among adult patients hospitalized with systemic lupus erythematosus. AB - Background Macrophage activation syndrome (MAS) is an uncommon but serious complication of systemic lupus erythematosus (SLE). We aimed to identify factors associated with MAS among adult hospitalized SLE patients. Methods Within the Brigham and Women's Hospital (BWH) Lupus Center Registry, we identified adult SLE patients > age 17 who had been hospitalized from 1970 to 2016, with either ferritin > 5000 ng/ml during admission or "macrophage activation syndrome" or "MAS" in discharge summary. We confirmed MAS by physician diagnosis in medical record review. We matched each hospitalized SLE patient with MAS to four SLE patients hospitalized without MAS (by SLE diagnosis date +/-1 year). We employed conditional logistic regression models to identify clinical factors associated with MAS among hospitalized SLE patients. Results Among 2094 patients with confirmed SLE, we identified 23 who had a hospitalization with MAS and compared them to 92 hospitalized without MAS. Cases and controls had similar age at SLE diagnosis (29.0 vs. 30.5, p = 0.60), and hospital admission (43.0 vs. 38.3, p = 0.80), proportion female (78% vs. 84%, p = 0.55), and time between SLE diagnosis and hospitalization (1971 vs. 1732 days, p = 0.84). Arthritis (OR 0.04 (95% CI 0.004-0.35)) and hydroxychloroquine use (OR 0.18 (95% CI 0.04-0.72)) on admission were associated with decreased MAS risk. Admission Systemic Lupus Erythematosus Disease Activity Index scores (30 vs. 19, p = 0.002) and lengths of stay (16 days vs. 3 days, p < 0.0001) were much higher among cases. Death during hospitalization was 19% among cases and 3% among controls ( p = 0.03). Conclusions In this case-control study of hospitalized adult SLE patients, arthritis and hydroxychloroquine use at hospital admission were associated with decreased MAS risk. Further studies are needed to validate these factors associated with lowered MAS risk. PMID- 29451070 TI - Confounders other than comorbidity explain survival differences in Danish and Swedish ovarian cancer patients - a comparative cohort study. AB - OBJECTIVE: Danish ovarian cancer (OC) patients have previously been found to have worse prognosis than Swedish patients, and comorbidity has been suggested as a possible explanation for this survival difference. We aimed to investigate the prognostic impact of comorbidity in surgically treated OC patients in Denmark and Sweden. METHODS: This comparative cohort study was based on data from 3118 surgically treated OC patients diagnosed in 2012-2015. The Swedish subcohort (n = 1472) was identified through the Swedish National Quality Register of Gynecological Surgery, whereas the Danish subcohort (n = 1646) originated from the Danish Gynecological Cancer Database. The clinical databases have high coverage and similar variables included. Comorbidity was classified according to the Ovarian Cancer Comorbidity Index and overall survival was the primary outcome. Data were analyzed using Kaplan Meier and Cox regression analyses. Multiple imputation was used to handle missing data. RESULTS: We found comparable frequencies of the following comorbidities: Hypertension, diabetes and 'Any comorbidity'. Arteriosclerotic cardiac disease and chronic pulmonary disease were more common among Swedish patients. Univariable survival analysis revealed a significant better prognosis for Swedish than for Danish patients (HR 0.84 [95% CI 0.74-0.95], p < .01). In adjusted multivariable analysis, Swedish patients had nonsignificant better prognosis compared to Danish patients (HR 0.91 [95% CI 0.80 1.04], p = .16). Comorbidity was associated with survival (p = .02) but comorbidity did not explain the survival difference between the two countries. CONCLUSIONS: Danish OC patients have a poorer prognosis than patients in Sweden but the difference in survival seems to be explained by other factors than comorbidity. PMID- 29451071 TI - Childhood emotional invalidation and right hemispheric mu suppression during a pain empathy task: An EEG study. AB - Empathy is a critical aspect of social behavior, and impairment in empathic processing is linked to hindered social interactions and several disorders. Despite much interest in this topic, our understanding of the developmental and neural involvement for empathic processing is limited. Recent evidence suggests the Mirror Neuron System (MNS) may play a role in this behavior, and that mu rhythm suppression found over the sensorimotor cortices may be a proxy for the MNS. Therefore, we aimed to measure mu rhythm oscillations in response to empathic processing during observation of painful action-based situations using electroencephalogram (EEG). Our second goal was to examine how perceived parental emotional invalidation (EI) during childhood may relate to empathy and influence mu suppression. Our results showed that mu rhythm suppression was strongest over the right hemisphere. EI had a significant influence on this suppression between painful and non-painful images, and was negatively correlated with behavioral measures of empathy. Our findings suggest that perceived childhood EI may decrease empathizing abilities and influence neural responses to the painful experiences of others. Implications from this study could entail clinical intervention targeted at emotional invalidation to foster the healthy development of empathy. PMID- 29451073 TI - Mental Health Problems Among Whistleblowers: A Comparative Study. AB - Whistleblowers play a very important and indispensable role in society and health care sector, but their act may elicit retaliation and other negative effects, which may impact their mental health. The main aim of the present comparative study is to assess to what extent whistleblowers ( N = 27) more often suffer from severe mental health problems than other population-based groups in the Netherlands, i.e., matched controls ( N = 135), cancer patients ( N = 130), persons with (partial) work disabilities ( N = 194), physically "healthy" persons ( N = 200), and general population ( N = 1026), using the 36-Item Short-Form Health Survey scales (for general mental health) and the Symptom Checklist-90 Revised scales (for specific mental health problems: depression, anxiety, agoraphobia, interpersonal sensitivity and distrust, and sleeping problems). Logistic regression analyses showed that the prevalence of general mental health problems was much higher than among matched controls and people with work disabilities but similar to cancer patient when controlling for demographics. About 85% suffered from severe to very severe anxiety, depression, interpersonal sensitivity and distrust, agoraphobia symptoms, and/or sleeping problems, and 48% reached clinical levels of these specific mental health problems. These specific mental health problems were much more prevalent than among the general population. PMID- 29451072 TI - Social Support for Exercise as a Predictor of Weight and Physical Activity Status Among Puerto Rican and Mexican Men: Results From the Latino Men's Health Initiative. AB - Social support is an important factor in increasing positive health outcomes and positive health behaviors across a variety of disease states including obesity. However, research examining the relationship between social support for exercise and weight and physical activity status, particularly among Latino men, is lacking. This paper examined whether social support for exercise predicted weight and physical activity status and whether the direction of these relationships differ as a function of Hispanic/Latino background (Puerto Rican/Mexican). Participants were 203 men who participated in a National Institutes of Health (NIH)-funded study addressing culture- and obesity-related variables. Both family participation social support and f amily rewards and punishment social support predicted higher weight status ( p < .005 and p < .05, respectively). Friend participation social support did not predict weight status. The direction of the relationship between weight status and family participation social support, family rewards and punishment social support, and friend participation social support did not significantly differ as a function of Hispanic/Latino background. The direction of the relationship between physical activity status and family participation social support, family rewards and punishment social support, and friend participation social support did not significantly differ as a function of Hispanic/Latino background. Findings suggest that increased social support for exercise from family members may be focused on those who need it most-overweight and obese participants. Additional research is needed to explore sociocultural factors that may promote social support, physical activity, and weight loss and maintenance in Puerto Rican and Mexican men. PMID- 29451074 TI - Negative emotional face perception is diminished on a very early level of processing in autism spectrum disorder. AB - Deficits in facial affect recognition (FAR) are often reported in autism spectrum disorder (ASD) due to inappropriate visual search strategies. It is unclear, however, whether or not deficits in subliminal FAR are still present in autism when visual focus is controlled. Thirteen persons with ASD and 13 healthy participants took part in this experiment. Supraliminal FAR was assessed using a standardized, computer-aided test. Subliminal FAR was obtained by an emotional face priming paradigm. By using an eye-tracking technique, it was assured that the initial visual focus was on the eyes of the prime. Persons with ASD showed worse FAR in supraliminal face recognition. Although controlled for initial gaze direction, participants also showed reduced negative face priming. These data confirm that FAR is disturbed already on a pre-attentive level in autism. PMID- 29451075 TI - Short-term outcomes of preoperative intra-aortic balloon pump use in patients undergoing adjunctive coronary endarterectomy: a retrospective observational study. AB - BACKGROUND: Coronary artery bypass grafting (CABG) combined with coronary endarterectomy (CE) can be associated with high operative mortality and morbidity. An intra-aortic balloon pump (IABP) has been the most widely used mechanical circulatory support device during perfusion treatment. However, the benefits of preoperative IABP in CABG combined with CE remain unknown. We conducted a retrospective observational study to evaluate the efficacy of preoperative IABP therapy in patients undergoing adjunctive right coronary artery (RCA) endarterectomy. METHODS: Between May 2013 and May 2016, 120 patients undergoing off-pump coronary artery bypass grafting (OPCABG) with RCA endarterectomy who received preoperative IABP support (IABP group, n=56) or who did not receive preoperative IABP support (control group, n=64) were evaluated retrospectively. RESULTS: Patients in the IABP group had a significantly lower mean preoperative ejection fraction and a significantly higher mean EuroSCORE (both <0.05). The incidence of inferior myocardial infarction (MI) was significantly lower in the IABP group than in the control group (3.6% vs 15.6%, RR = 0.23, 95% CI 0.05-1.00, p=0.03). Hospital mortality was similar in the two groups (3.6% vs 4.7%, RR= 0.76, 95% CI 0.13-4.40, p=0.76). There were no significant differences between the two groups with respect to the rates of prolonged ventilation, low cardiac output syndrome, renal failure requiring dialysis, re-operation for bleeding or IABP-related complications. Preoperative IABP may be a protective factor of inferior MI (HR = 0.031, 95% CI 0.004-0.211, p<0.001) Conclusions: The preoperative use of IABP could reduce the incidence of postoperative MI in patients undergoing CABG with CE and seemed to shift high risk patients into a lower-risk category. PMID- 29451076 TI - Similarity and decision time in preferential choice. AB - Choice option similarity is a key contextual variable in multiattribute choice. Based on theories of preference accumulation, we predicted that decision times would be longer when the available choice options were similar compared with when they were dissimilar, controlling for the relative desirabilities of the options. We tested for the relationship between similarity and decision time in an experiment involving incentivised binary choices between items of equivalent desirability and found that our predictions were confirmed. Our results show how the effects of contextual factors on key decision variables can be accurately predicted by existing computational theories of decision-making. PMID- 29451077 TI - Intravitreal Aflibercept Versus Ranibizumab for Wet Age-Related Macular Degeneration: A Cost-effectiveness Analysis. AB - BACKGROUND: Age-related macular degeneration (AMD) is the leading cause of vision loss in the United States. The most severe vision loss occurs in patients with neovascular AMD, known as wet AMD (wAMD). The most commonly used antivascular endothelial growth factor (VEGF) therapies approved by the FDA to treat patients with wAMD are ranibizumab, 0.5 mg administered by intravitreal injection once a month (approximately every 28 days), and intravitreal aflibercept injection (IAI), 2 mg every 4 weeks (monthly) for the first 12 weeks (3 months), followed by IAI 2 mg once every 8 weeks (2 months). Given the similar efficacy and safety profiles between IAI and ranibizumab, their associated costs and comparative cost effectiveness are key factors in determining which one represents a more rational investment of scarce health care resources to help address the increasing cost of prescription drugs in the United States, a source of concern for patients, prescribers, payers, and policymakers. OBJECTIVE: To assess the cost effectiveness of intravitreal aflibercept injection 2 mg every 8 weeks after 3 initial monthly doses (IAI 2q8) versus ranibizumab 0.5 mg monthly (Rq4) and pro re nata (PRN) in the treatment of patients with wAMD from a U.S. payer perspective. METHODS: A Markov cohort model was developed to estimate the lifetime quality-adjusted life-years (QALYs) and costs of treating patients with wAMD with IAI 2q8, Rq4, and ranibizumab PRN. The model considered changes in best corrected visual acuity in the affected and fellow eyes over time, and the effect of blindness on mortality. Efficacy for IAI 2q8 and Rq4 was from VIEW 1 and VIEW 2 studies and from the Comparison of AMD Treatments Trials for ranibizumab PRN. Utilities and costs (in 2016 U.S. dollars) were from published literature. Health outcomes and costs were discounted at an annual rate of 3%. RESULTS: Over a lifetime, IAI 2q8 provided equal health benefits with Rq4 (5.44 QALYs) at a lower total cost ($33,745 vs. $48,031) as a result of fewer injections. IAI 2q8 yielded slightly greater QALYs versus ranibizumab PRN (5.44 vs. 5.40) at a slightly higher cost ($33,745 vs. $33,652), with an incremental cost per QALY gained of $2,583. Results were sensitive to variations in drug acquisition costs and number of injections of both drugs and the baseline age of the cohort. CONCLUSIONS: IAI 2q8 can be cost saving and cost-effective compared with Rq4 and ranibizumab PRN for the treatment of wAMD in the United States.

PMID- 29451078 TI - Oncologists' Perceptions of Drug Affordability Using NCCN Evidence Blocks: Results from a National Survey. AB - BACKGROUND: The increasing prevalence of cancer coupled with approvals of new drugs and technologies used in therapy have brought increased scrutiny to the cost and value of treatments in oncology. To address the rising concern about oncology drug costs, several organizations have developed value frameworks to help assess the value of oncology regimens. The objective of this study was to assess oncologists' perceptions, awareness, and knowledge of all oncology value frameworks in the United States and to understand oncologists' perceptions of affordability in the context of National Comprehensive Cancer Network (NCCN) Evidence Blocks. OBJECTIVES: To (a) assess oncologists' awareness, knowledge, perceptions, and ratings of the American Society of Clinical Oncology Value Framework (AVF), the Institute for Clinical and Economic Review (ICER) value framework, NCCN Evidence Blocks, and Memorial Sloan Kettering Cancer Center's DrugAbacus; (b) assess oncologists' knowledge and perceptions of drug affordability as defined by the NCCN Evidence Blocks methodology; and (c) determine the factors that influence drug affordability ratings. METHODS: Data were collected from an electronic cross-sectional survey of 200 U.S.-based oncologists from a variety of practice settings. Oncologists were asked about their knowledge and perceptions of 4 value frameworks-NCCN Evidence Blocks, AVF, the ICER value framework, and DrugAbacus. Using NCCN Evidence Blocks, oncologists were asked to rate a variety of hypothetical cancer therapies and assign costs (in U.S. dollars) to the 5 levels of affordability. Additional questions that assessed perceived patient out-of-pocket (OOP) costs and comfort level in assessing affordability were also included in the survey. RESULTS: Oncologists were most familiar with NCCN Evidence Blocks (90%), followed by the AVF (84%), ICER value framework (57%), and DrugAbacus (56%). Oncologists rated affordability higher (mean rating 3: moderately expensive) versus the actual NCCN panel affordability rating (mean rating 1: very expensive). The affordability rating was similar across a variety of hypothetical cancer therapies and tumor types (rating: 3). Oncologists estimated the costs for this rating of 3 to range from $4,600 to $6,000 per month, which was inconsistent with actual drug costs. Oncologists estimated the mean monthly OOP costs for patients with insurance to range from $1,260 for a new oral medication to $1,700 for a new infused medication. Only 26% of oncologists were comfortable or very comfortable with rating costs associated with affordability levels. CONCLUSIONS: Surveyed oncologists rated cancer therapies as more affordable (per NCCN Evidence Blocks criteria) than NCCN panel ratings. Costs associated with affordability were not consistent with actual treatment costs; however, most oncologists were not comfortable with rating affordability. Patient OOP costs had the biggest influence on affordability ratings; however, physicians overestimated patient OOP costs significantly. There is an opportunity to improve the value frameworks, especially with regard to affordability assessment. DISCLOSURES: This study was funded by Genentech.

PMID- 29451079 TI - Paired associate learning deficits in poor readers: The contribution of phonological input and output processes. AB - It is well-established that poor readers exhibit deficits in paired associate learning (PAL), and there is increasing evidence for a phonological locus of these deficits. However, it remains unclear whether poor performance stems from difficulties specific to the phonological output system or difficulties that affect both phonological input and output processes. Understanding these deficits is important not only in the context of PAL but also for informing broader theories of typical and atypical reading development. We developed a novel paradigm that allowed us to assess PAL in the presence and absence of phonological output demands. In total, 14 poor readers and 14 age-matched controls were first trained to criterion in verbal-visual PAL before being tested in the visual-verbal direction. The results showed that poor readers learned at the same rate as controls in verbal-visual PAL, even when the nonword stimuli were phonologically confusable. Yet, despite having reached the same criterion as controls in verbal-visual PAL, poor readers exhibited robust impairments for those same paired associates in visual-verbal PAL. The overall pattern of results is most consistent with the conclusion that PAL deficits reflect impairments to the phonological output system; however, results that may challenge this interpretation are also discussed. PMID- 29451080 TI - Relationships between social skills and self-esteem in nurses: a questionnaire study. AB - BACKGROUND: Our study attempts to evaluate whether nurses' social skills are related to their self-concept and self-esteem. METHODS: A descriptive survey study was developed to 464 nurses who had worked for a minimum of one year in adult or pediatric services. The Rosenberg Self-Esteem Scale (RSE) and the Scale of Social Skills (SSS) by Gismero were used to measure nurses' self-esteem and social skills, respectively. RESULTS: Evaluation of self-esteem and social skills revealed no significant associations between sex and specific nursing speciality, (p > .05). Significant differences were observed based on the marital status for RSE and SSS Factor 1 (RSE, p = .013; SSS-F1, p = .033). Correlation and regression analyses demonstrated a significant correlation between nurse self esteem and some social skills factors. CONCLUSION: This study shows that there exists a relationship between higher self-esteem and self-concept among nurses and this issue can affect effective communication with patients. PMID- 29451082 TI - The Short-Term Placebo Response in Children With Attention-Deficit Hyperactivity Disorder (ADHD). AB - To assess short-term placebo response in 6- to 13-year-old children with ADHD, children who were administered a double-blind placebo-methylphenidate trial, 1 week each, were included in the analysis. Conners' parents and Teacher Rating scales, the Aggregate Neurobehavioral Student Health and Educational Review inventory, and the Matching Familiar Figure Test were employed. A reduction of 30% or more in one or more of the teachers report subscales was observed in 18.8% of the participants. Attention test performance resulted in 58% of children exhibiting reduction in error rates and 36.2% exhibited longer latency period. Significant correlations between placebo response and methylphenidate response in all of the teachers report subscales were found. Base line severity, learning problem and emotional status were found associated with placebo response. Short term placebo response should be accounted for in children with ADHD. PMID- 29451081 TI - Permethrin treated clothing to protect outdoor workers: evaluation of different methods for mosquito exposure against populations with differing resistance status. AB - Minimizing arthropod exposure (e.g. mosquito and tick bites) is vital to protect health of outdoor workers. Personal protective measures can help protect against exposure. Here, the quantity of permethrin was evaluated for different fabric types after washing. Cone and petri dish exposure assays were used to investigate the knockdown/mortality of permethrin-susceptible and permethrin-resistant populations of mosquitoes. Permethrin-treated clothing was effective against the tested mosquito population that was susceptible to permethrin but not a permethrin-resistant population. Permethrin quantity was significantly highest in the 100% cotton fabric and for the 0 wash group. Permethrin quantity in fabrics decreased with washing. No significant differences (p > 0.05) were observed in knockdown/mortality rates for either exposure method. The protective effect of permethrin-treated clothing against mosquitoes is impacted by many factors, e.g. wash frequency, fabric type, and the susceptibility/resistance status of local mosquito populations.

Here, we report a case of obstruction of the upper respiratory tract due to assassin bug ( Cydnocoris gilvus) where allegations of medical negligence were made by relatives of the deceased. Autopsy findings demonstrated that an insect was present inside the larynx, lodged at the epiglottis. Multiple haemorrhagic patches were present at the base of the tongue, larynx, epiglottis, vocal cords and tracheal bifurcation. As Reduviidae can be successfully used as a biological pest-control agents, they should be used with due precaution. PMID- 29451086 TI - Efficient robust doubly adaptive regularized regression with applications. AB - We consider the problem of estimation and variable selection for general linear regression models. Regularized regression procedures have been widely used for variable selection, but most existing methods perform poorly in the presence of outliers. We construct a new penalized procedure that simultaneously attains full efficiency and maximum robustness. Furthermore, the proposed procedure satisfies the oracle properties. The new procedure is designed to achieve sparse and robust solutions by imposing adaptive weights on both the decision loss and the penalty function. The proposed method of estimation and variable selection attains full efficiency when the model is correct and, at the same time, achieves maximum robustness when outliers are present. We examine the robustness properties using the finite-sample breakdown point and an influence function. We show that the proposed estimator attains the maximum breakdown point. Furthermore, there is no loss in efficiency when there are no outliers or the error distribution is normal. For practical implementation of the proposed method, we present a computational algorithm. We examine the finite-sample and robustness properties using Monte Carlo studies. Two datasets are also analyzed. PMID- 29451087 TI - Multiple imputation with sequential penalized regression. AB - Missing data is a common issue that can cause problems in estimation and inference in biomedical, epidemiological and social research. Multiple imputation is an increasingly popular approach for handling missing data. In case of a large number of covariates with missing data, existing multiple imputation software packages may not work properly and often produce errors. We propose a multiple imputation algorithm called mispr based on sequential penalized regression models. Each variable with missing values is assumed to have a different distributional form and is imputed with its own imputation model using the ridge penalty. In the case of a large number of predictors with respect to the sample size, the use of a quadratic penalty guarantees unique estimates for the parameters and leads to better predictions than the usual Maximum Likelihood Estimation (MLE), with a good compromise between bias and variance. As a result, the proposed algorithm performs well and provides imputed values that are better even for a large number of covariates with small samples. The results are compared with the existing software packages mice, VIM and Amelia in simulation studies. The missing at random mechanism was the main assumption in the simulation study. The imputation performance of the proposed algorithm is evaluated with mean squared imputation error and mean absolute imputation error. The mean squared error ([Formula: see text]), parameter estimates with their standard errors and confidence intervals are also computed to compare the performance in the regression context. The proposed algorithm is observed to be a good competitor to the existing algorithms, with smaller mean squared imputation error, mean absolute imputation error and mean squared error. The algorithm's performance becomes considerably better than that of the existing algorithms with increasing number of covariates, especially when the number of predictors is close to or even greater than the sample size. Two real-life datasets are also used to examine the performance of the proposed algorithm using simulations. PMID- 29451088 TI - A marginalized two-part model with heterogeneous variance for semicontinuous data. AB - Semicontinuous data, characterized by a point mass at zero followed by a positive, continuous distribution, arise frequently in medical research. These data are typically analyzed using two-part mixtures that separately model the probability of incurring a positive outcome and the distribution of positive values among those who incur them. In such a conditional specification, however, standard two-part models do not provide a marginal interpretation of covariate effects on the overall population. We have previously proposed a marginalized two part model that yields more interpretable effect estimates by parameterizing the model in terms of the marginal mean. In the original formulation, a constant variance was assumed for the positive values. We now extend this model to a more general framework by allowing non-constant variance to be explicitly modeled as a function of covariates, and incorporate this variance into two flexible distributional assumptions, log-skew-normal and generalized gamma, both of which take the log-normal distribution as a special case. Using simulation studies, we compare the performance of each of these models with respect to bias, coverage, and efficiency. We illustrate the proposed modeling framework by evaluating the effect of a behavioral weight loss intervention on health care expenditures in the Veterans Affairs health system. PMID- 29451089 TI - Randomization-based inference for Bernoulli trial experiments and implications for observational studies. AB - We present a randomization-based inferential framework for experiments characterized by a strongly ignorable assignment mechanism where units have independent probabilities of receiving treatment. Previous works on randomization tests often assume these probabilities are equal within blocks of units. We consider the general case where they differ across units and show how to perform randomization tests and obtain point estimates and confidence intervals. Furthermore, we develop rejection-sampling and importance-sampling approaches for conducting randomization-based inference conditional on any statistic of interest, such as the number of treated units or forms of covariate balance. We establish that our randomization tests are valid tests, and through simulation we demonstrate how the rejection-sampling and importance-sampling approaches can yield powerful randomization tests and thus precise inference. Our work also has implications for observational studies, which commonly assume a strongly ignorable assignment mechanism. Most methodologies for observational studies make additional modeling or asymptotic assumptions, while our framework only assumes the strongly ignorable assignment mechanism, and thus can be considered a minimal assumption approach.

AB - Chronic hepatitis C virus (HCV) infection is associated with altered metabolism, including dyslipidemia and insulin resistance. These contribute to disease progression and influences the response to therapy. To investigate the relationships of new direct-acting antiviral drugs, simeprevir/sofosbuvir, with lipid profile and insulin resistance (IR). Eighty chronic hepatitis C genotype 4 patients were included; they were divided into four groups according to the severity of fibrosis as detected by fibroscan. Forty healthy persons volunteered as a control group. Lipid profile changes and IR were analyzed at baseline and after the end of treatment, and any effect of these changes on the response to treatment was studied. Before treatment, the levels of serum triglycerides were significantly higher in patients than in the control, and the levels of fasting insulin showed a progressive increase with advancing stage of fibrosis. At the end of treatment, there were a significant reduction in serum triglycerides, FBS, fasting insulin, and homeostasis model for the assessment of IR (P < 0.001), and a significant elevation of serum cholesterol and low-density lipoprotein (LDL)-c, high-density lipoprotein (HDL)-c, and LDL/HDL ratio (P = 0.001). An end-of treatment response (week 12) was achieved in (99%) of the treated cases with 99% sustained viral response for 12 weeks post-treatment (week 24). Significant lipid profile changes were detected at the end of treatment. Serum lipid levels and IR are no longer predictors of response to DAAs. Follow-up of the lipid profile is warranted to avoid any possible remote effect of atherosclerotic heart disease. PMID- 29451091 TI - Comparing the effects of education using telephone follow-up and smartphone-based social networking follow-up on self-management behaviors among patients with hypertension. AB - BACKGROUND: Little is known about the benefits of social networks in the management of patients. OBJECTIVE: The aim of this study was to compare the effects of self-management (SM) education using telephone follow-up and mobile phone-based social networking on SM behaviors among patients with hypertension. METHODS: This randomized clinical trial was conducted with 100 patients. They were randomly allocated to four groups: (i) control, (ii) SM training without follow-up, (iii) telephone follow-up and (iv) smartphone-based social networking follow-up. The hypertension SM behavior questionnaire was used for data collection before and six weeks after the study. RESULTS: Those patients who underwent SM education training (with and without follow-up) had statistically significant differences from those in the control group in terms of SM behaviors (p < .001). There was no statistically significant difference between different types of follow-up. CONCLUSION: SM education using telephone follow-up and/or smartphone-based social networking follow-up influenced SM behaviors among patients with hypertension.

AB - Automated driving has the potential to improve the safety and efficiency of future traffic and to extend elderly peoples' driving life, provided it is perceived as comfortable and joyful and is accepted by drivers. Driving comfort could be enhanced by familiar automated driving styles based on drivers' manual driving styles. In a two-stage driving simulator study, effects of driving automation and driving style familiarity on driving comfort, enjoyment and system acceptance were examined. Twenty younger and 20 older drivers performed a manual and four automated drives of different driving style familiarity. Acceptance, comfort and enjoyment were assessed after driving with standardised questionnaires, discomfort during driving via handset control. Automation increased both age groups' comfort, but decreased younger drivers' enjoyment. Younger drivers showed higher comfort, enjoyment and acceptance with familiar automated driving styles, whereas older drivers preferred unfamiliar, automated driving styles tending to be faster than their age-affected manual driving styles. Practitioner Summary: Automated driving needs to be comfortable and enjoyable to be accepted by drivers, which could be enhanced by driving style individualisation. This approach was evaluated in a two-stage driving simulator study for different age groups. Younger drivers preferred familiar driving styles, whereas older drivers preferred driving styles unaffected by age. PMID- 29451094 TI - Growth and optimization of carbon nanotubes in powder activated carbon for an efficient removal of methylene blue from aqueous solution. AB - This work demonstrated the synthesis of carbon nanotubes (CNTs) on powder activated carbon (PAC) impregnated with Ni-catalyst through chemical vapour deposition. The optimized effects of reaction temperature, time and feedstock flow rates on CNT growth were examined. Potassium permanganate (KMnO4) and potassium permanganate in acidic solution (KMnO4/H2SO4) were used to functionalize CNTs samples. A primary screening of methylene blue (MB) adsorption was conducted. The chemical, physical and morphological properties of the adsorbent with the highest removal efficiency were investigated using FESEM, EDX, TEM, BET surface area, RAMAN, TGA, FTIR, and zeta potential. The resulting carbon nanotube-loaded activated carbons possessed abundant pore structure and large surface area. The MB removal by the as-synthesized CNTs was more remarkable than that by the modified samples. Adsorption studies were carried out to evaluate the optimum conditions, kinetics and isotherms for MB adsorption process. The response surface methodology-central composite design (RSM-CCD) was used to optimize the adsorption process parameters, including pH, adsorbent dosage and contact time. The investigation of the adsorption behaviour demonstrated that the adsorption was well fitted with the pseudo-second-order model and Langmuir isotherm with the maximum monolayer adsorption capacity of 174.5 mg/g. Meanwhile, the adsorption of MB onto adsorbent was driven by the electrostatic attraction and pi-pi interaction. Moreover, the as-obtained CNT-PAC exhibited good reusability after four repeated operations. In view of these empirical findings, the low-cost CNT-PAC has potential for removal of MB from aqueous solution. PMID- 29451093 TI - Adjustment for time-invariant and time-varying confounders in 'unexplained residuals' models for longitudinal data within a causal framework and associated challenges. AB - 'Unexplained residuals' models have been used within lifecourse epidemiology to model an exposure measured longitudinally at several time points in relation to a distal outcome. It has been claimed that these models have several advantages, including: the ability to estimate multiple total causal effects in a single model, and additional insight into the effect on the outcome of greater-than expected increases in the exposure compared to traditional regression methods. We evaluate these properties and prove mathematically how adjustment for confounding variables must be made within this modelling framework. Importantly, we explicitly place unexplained residual models in a causal framework using directed acyclic graphs. This allows for theoretical justification of appropriate confounder adjustment and provides a framework for extending our results to more complex scenarios than those examined in this paper. We also discuss several interpretational issues relating to unexplained residual models within a causal framework. We argue that unexplained residual models offer no additional insights compared to traditional regression methods, and, in fact, are more challenging to implement; moreover, they artificially reduce estimated standard errors. Consequently, we conclude that unexplained residual models, if used, must be implemented with great care.

The opening line of Dickens's A Tale of Two Cities could easily be the dramatic opening line of a summary of the establishment of a satellite medical school campus in Manitoba. Reflection on my last four years as associate dean reveals that most of the descriptors in that famous sentence at one time or another were apropos. This brief essay will relate the experiences of the last four years and some of the lessons learned along the way. PMID- 29451096 TI - Elevated CRP at admission predicts post-stroke cognitive impairment in Han Chinese patients with intracranial arterial stenosis. AB - OBJECTIVES: Elevated C-reactive protein (CRP) levels have been associated with cognitive deficits in certain patient populations, but whether this is also true of ischemic stroke patients is controversial. This study aims to examine the possible association between CRP concentration and post-stroke cognitive impairment (PSCI) in Han Chinese patients and to determine whether this association depends on intracranial arterial stenosis (ICAS). METHODS: Patients with mild or moderate stroke admitted to a large regional medical center in Western China were consecutively enrolled in our study. Serum levels of CRP and ICAS severity were assessed at admission and cognitive status was assessed 6 months after stroke using the Six-Item Screener. RESULTS: Of the 1116 patients included in our study, no association was observed between CRP levels at admission and cognitive performance at 6 months. However, among the subgroup of 311 patients with ICAS, a significant association did exist, and it persisted even after adjusting for potential confounders (OR 1.038, 95% CI 1.015-1.061). We did not find the same association in the subgroup of the patients without ICAS. CONCLUSIONS: To our knowledge, this is the first study to explore the effects of CRP on PSCI in Han Chinese with ICAS. Our findings indicate that higher CRP levels at admission are associated with subsequent cognitive decline in Han Chinese patients with ICAS following ischemic stroke. Further studies in other ethnic groups are needed to validate the use of CRP to predict dementia in ICAS patients.

PMID- 29451098 TI - The association between preaxial polydactyly and radial longitudinal deficiency in syndromic cases: a report on nine families. AB - : Preaxial polydactyly and radial longitudinal deficiency are usually viewed as two different entities. We present nine families with different disorders in which both preaxial polydactyly and radial longitudinal deficiency were seen in the phenotype. This indicates that both entities may be caused by the same developmental error or insult. The pathogenesis is complex and may be related to the interactions of two signalling loops: the first loop (named as the radial longitudinal deficiency loop) contains genes/proteins responsible for the development of the radial ray; and the second loop (named as the preaxial polydactyly loop) contains the Sonic Hedgehog involved in the pathogenesis of preaxial polydactyly. This entity is named as the preaxial polydactyly-radial longitudinal deficiency association and should be included in the description of the preaxial polydactyly spectrum. LEVEL OF EVIDENCE: IV.

AB - Arthroscopic management of thumb carpometacarpal (CMC) osteoarthrosis (OA) is an approach that has unclear results. We performed a systematic review encompassing three electronic databases up to May 2016 for studies describing arthroscopic assisted techniques for thumb CMC OA. Meta-analyses of visual analogue scores (VAS) for pain, Disabilities of the Arm, Shoulder and Hand (DASH) scores, grip strength and pinch strength before and after arthroscopy were performed for ten included non-randomized cohort studies comprising 294 patients. Based on Hedges' g measure, we found a large effect on VAS and DASH scores, a small effect on grip strength and no effect on pinch strength. On average, VAS improved by 4.1 cm, DASH by 22 points and grip strength by 2.8 kg. Complications were reported in 4% of patients. The use of arthroscopic-assisted techniques for thumb CMC OA is still limited; however, it may be a reasonable option for patients with thumb CMC OA who do not respond to non-operative treatment.

In the case of Deaf Community healthcare interactions could be affected by communication and it can also have a negative impact on health and jeopardise some of their health rights. OBJECTIVES: Aims (i) know the communication access difficulties of deaf people in healthcare context (ii) determine how these difficulties violate their rights. METHODS: Ethnographical study. RESULTS: Subjects were 25 deaf adults (7 men; 18 women). Two themes were identified (1) barriers to information access - right to information; (2) communication barriers - right to privacy and to decide. CONCLUSIONS: Communication difficulties and access to information have an impact on the health of deaf people, and violate health rights. In addition, their language rights like a community are also violate. Impact statement: Research could have a positive impact on improvement to access, communication and safe in the Deaf Community, in a clinical context.

AB - OBJECTIVE AND IMPORTANCE: Late postpartum eclampsia is characterized by pre eclampsia and tonic-clonic seizures presenting more than 48 hours postpartum. It is a rare, frightening and dangerous complication that requires rapid recognition and adequate treatment. CLINICAL PRESENTATION: We present a case of late postpartum eclampsia, initially diagnosed as right-sided heart failure, 10 days postpartum.Two days after the delivery she developed mild swelling of both feet, progressive shortness of breath on exertion and orthopnea. INTERVENTION: Transthoracic echocardiography revealed sever tricuspid regurgitation in combination with pulmonary hypertension. The patient wasadmitted to the intensive care unit (ICU) and a tentative diagnosis of pulmonary hypertension was made. On arrival in the ICU, the patient developed a tonic-clonic seizure and urinalysis revealed proteinuria, indicating eclampsia. Treatment of eclampsia was initiated with complete resolution of symptoms. CONCLUSION: This caseemphasizes the importance of considering late postpartum eclampsia in patients presenting with signs of pulmonary edema even several days after delivery, as early diagnosis and prompt initiation of appropriate antihypertensive and anticonvulsant therapy can prevent severe complications.

AB - Objectives To explore the effect of electromotive drug administration of mitomycin C (EMDA-MMC) using a single dose of intravesical mitomycin C (MMC) to avoid transurethral resection (TURBT) for small non-muscle-invasive bladder cancer. Material and methods All patients presenting small (<2 cm), single or multiple papillary bladder tumors were proposed to undergo a single EMDA-MMC instillation with 60 mg MMC before planning TURBT. The end point is complete disappearance of all papillary tumors at 2-4 weeks after EMDA-MMC. Results Thirty six instillations were given to 32 patients. In general the treatment was well supported, except for two patients who had severe bladder spasms, resulting in early evacuation of the MMC. Complete response occurred in 28% (10/36 instillations). In 4 EMDA-MMCs with multiple tumors some tumors disappeared while others remained. In 61% (22/36) the tumors remained unchanged. Conclusion A single EMDA-MMC in l papillary bladder tumors <2 cm gives insufficient ablative effect. PMID- 29451103 TI - Effects of combustion temperature on air emissions and support fuel consumption in full scale fluidized bed sludge incineration: with particular focus on nitrogen oxides and total organic carbon. AB - This article describes a pilot test at a sewage sludge incineration plant and shows its results considering the impacts of reducing the minimum combustion temperature from 850 degrees C to 800 degrees C. The lowering leads to an actual reduction of the average combustion temperature by 25 K and a significant reduction in the fuel oil consumption for support firing. The test shall be used for providing evidence that the changed combustion conditions do not result in higher air pollutant emissions. The analysis focusses on the effects of the combustion temperature on nitrogen oxides (NOx) and total organic carbon emissions. The evaluation of all continuously monitored emissions shows reduced emission levels compared to the previous years, especially for NOx. PMID- 29451104 TI - A multi-criteria decision-making approach to rank supplier selection criteria for hospital waste management: A case from Pakistan. AB - To address environmental issues and cost effectiveness, waste management is necessary for healthcare facilities. Most importantly, segregation of hazardous and non-hazardous waste must be done as in many developing countries; disposal of both types of healthcare waste is done together, which is an unsafe practice. Waste generated in hospitals needs proper management to minimise hazards for patient and healthcare workers. At the same time, it is quite difficult for hospitals to find a systematic way to select appropriate suppliers for hospital waste management. Therefore, the purpose of this article is to identify, validate, and rank criteria that are essential for hospital waste management suppliers' selection. The analytical hierarchal process approach has been used and a survey from Pakistan's largest city (Karachi) has been considered to rank the most appropriate criteria that is necessary to select the supplier, especially in a developing country like Pakistan. Results show that waste management cost (45.5%) and suppliers' details (31.5%) are the top two main criteria for supplier selection; and storage cost (15.7%), waste handling cost (14.7%), and qualification of the suppliers (10.9%) are the top three most important overall sub-criteria for supplier selection for hospital waste management. PMID- 29451106 TI - Thinking in a Foreign language reduces the causality bias. AB - The purpose of this research is to investigate the impact of a foreign language on the causality bias (i.e., the illusion that two events are causally related when they are not). We predict that using a foreign language could reduce the illusions of causality. A total of 36 native English speakers participated in Experiment 1, 80 native Spanish speakers in Experiment 2. They performed a standard contingency learning task, which can be used to detect causal illusions. Participants who performed the task in their native tongue replicated the illusion of causality effect, whereas those performing the task in their foreign language were more accurate in detecting that the two events were causally unrelated. Our results suggest that presenting the information in a foreign language could be used as a strategy to debias individuals against causal illusions, thereby facilitating more accurate judgements and decisions in non contingent situations. They also contribute to the debate on the nature and underlying mechanisms of the foreign language effect, given that the illusion of causality is rooted in basic associative processes. PMID- 29451105 TI - Human-automation interaction for multiple robot control: the effect of varying automation assistance and individual differences on operator performance. AB - In a human-automation interaction study, automation assistance level (AL) was investigated for its effects on operator performance in a dynamic, multi-tasking environment. Participants supervised a convoy of manned and unmanned vehicles traversing a simulated environment in three AL conditions, while maintaining situation awareness and identifying targets. Operators' situation awareness, target detection performance, workload and individual differences were evaluated. Results show increasing AL generally improved task performance and decreased perceived workload, however, differential effects due to operator spatial ability and perceived attentional control were found. Eye-tracking measures were useful in parsing out individual differences that subjective measures did not detect. At the highest AL, participants demonstrated potentially complacent behaviour, indicating task disengagement. Practitioner Summary: The effect of varying automation assistance level (AL) on operator performance on multiple tasks were examined in a within-subjects experiment. Findings indicated a moderate AL improved performance, while higher levels encouraged complacent behaviour. Effects due to individual differences suggest that effective AL depends on the underlying characteristics of the operator. PMID- 29451108 TI - Editorial: Smart Drug Delivery Systems (Part 1). PMID- 29451107 TI - Bilaterally Combined Electric and Acoustic Hearing in Mandarin-Speaking Listeners: The Population With Poor Residual Hearing. AB - The hearing loss criterion for cochlear implant candidacy in mainland China is extremely stringent (bilateral severe to profound hearing loss), resulting in few patients with substantial residual hearing in the nonimplanted ear. The main objective of the current study was to examine the benefit of bimodal hearing in typical Mandarin-speaking implant users who have poorer residual hearing in the nonimplanted ear relative to those used in the English-speaking studies. Seventeen Mandarin-speaking bimodal users with pure-tone averages of ~80 dB HL participated in the study. Sentence recognition in quiet and in noise as well as tone and word recognition in quiet were measured in monaural and bilateral conditions. There was no significant bimodal effect for word and sentence recognition in quiet. Small bimodal effects were observed for sentence recognition in noise (6%) and tone recognition (4%). The magnitude of both effects was correlated with unaided thresholds at frequencies near voice fundamental frequencies (F0s). A weak correlation between the bimodal effect for word recognition and unaided thresholds at frequencies higher than F0s was identified. These results were consistent with previous findings that showed more robust bimodal benefits for speech recognition tasks that require higher spectral resolution than speech recognition in quiet. The significant but small F0-related bimodal benefit was also consistent with the limited acoustic hearing in the nonimplanted ear of the current subject sample, who are representative of the bimodal users in mainland China. These results advocate for a more relaxed implant candidacy criterion to be used in mainland China. PMID- 29451109 TI - [Orthostatic hypotension in elderly patients]. AB - - Orthostatic hypotension is a condition in which there is insufficient recovery of the blood pressure drop which occurs after getting up, which causes a temporary reduction of cerebral perfusion. This increases the risk of falls resulting in injuries.- Orthostatic hypotension is most common in the elderly. The cause is usually multifactorial (including reduced circulating volume, reduced peripheral resistance and limited heart rate increase). Orthostatic hypotension caused by autonomic dysfunction is called neurogenic orthostatic hypotension.- The most important groups of drugs that may elicit orthostatic hypotension are: diuretics (but only if they lead to hypovolaemia), antidepressants (mainly tricyclic antidepressants), sympatholytics (alpha blockers as well as beta-blockers) and vasodilators (for example, nitrates).- Treatment of the elderly with orthostatic hypotension starts with lifestyle advice (getting up slowly) and possible medication adjustments. PMID- 29451110 TI - [Risk of heart failure diminished thanks to stomach reduction in obesity]. AB - BACKGROUND: Obesity is a chronic disease and a risk factor for heart failure. In end-stage heart failure, heart transplantation may be the only available treatment option, but obesity is a contraindication for this treatment because of its unfavourable prognosis. Bariatric surgery and its subsequent weight loss may affect the indication for transplantation in patients with heart failure and morbid obesity. CASE DESCRIPTION: A 46-year-old patient with morbid obesity and heart failure underwent gastric sleeve resection in preparation of a heart transplantation. Without it, he would not have been considered eligible for transplantation because of his obesity. The bariatric intervention was also intended to use weight loss as a way to reduce the symptoms of his heart failure and to make rehabilitation possible. One year after surgery, the condition of the patient had improved so much that heart transplantation was no longer necessary. CONCLUSION: Bariatric surgery is safe for morbidly obese patients with severe heart failure and may sometimes even avoid heart transplantation.

AB - In the Telephone First approach that has been introduced in the UK, within a few hours of patients contacting their GP practice a general practitioner will call back all patients who want to make an appointment within a few hours. We think that it is not wise to introduce this system in the Netherlands. Research has not shown sufficient advantages and the system hampers rethinking the traditional way of handling patient requests and the growing workload in general practice. Instead, focus should be paid to more diverse and innovative ways of dealing with patient demands. PMID- 29451114 TI - Molecular Tools To Study Preharvest Food Safety Challenges. AB - Preharvest food safety research and activities have advanced over time with the recognition of the importance and complicated nature of the preharvest phase of food production. In developed nations, implementation of preharvest food safety procedures along with strict monitoring and containment at various postharvest stages such as slaughter, processing, storage, and distribution have remarkably reduced the burden of foodborne pathogens in humans. Early detection and adequate surveillance of pathogens at the preharvest stage is of the utmost importance to ensure a safe meat supply. There is an urgent need to develop rapid, cost effective, and point-of-care diagnostics which could be used at the preharvest stage and would complement postmortem and other quality checks performed at the postharvest stage. With newer methods and technologies, more efforts need to be directed toward developing rapid, sensitive, and specific methods for detection or screening of foodborne pathogens at the preharvest stage. In this review, we will discuss the molecular methods available for detection and molecular typing of bacterial foodborne pathogens at the farm. Such methods include conventional techniques such as endpoint PCR, real-time PCR, DNA microarray, and more advanced techniques such as matrix-assisted layer desorption ionization-time of flight mass spectrometry and whole-genome sequencing. PMID- 29451115 TI - Understanding the Complexities of Food Safety Using a "One Health" Approach. AB - The philosophy of One Health is growing in concept and clarity. The interdependence of human, animal, and environmental health is the basis for the concept of One Health. One Health is a comprehensive approach to ensure the health of people, animals, and the environment through collaborative efforts. Preharvest food safety issues align with the grand concept of One Health. Imagine any food production system, and immediately, parallel images from One Health emerge: for example, transmission of zoonotic diseases, antibiotic residues, or resistance genes in the environment; environmental and animal host reservoirs of disease; challenges with rearing animals and growing fresh produce on the same farm; application and transport of manure or diseased animals. During a recent celebration of #OneHealthDay, information was shared around the globe concerning scientists dedicated to One Health research systems. An ever-growing trade and global commerce system mixed with our incessant desire for food products during the whole year makes it all the more important to take a global view through the One Health lens to solve these growing challenges. The recent explosion of Zika virus around the globe renewed the need for assessing transmissible diseases through the eyes of One Health. It is not good enough to know how a disease affects the human population without a thorough understanding of the environment and vector reservoirs. If 60 to 75% of infectious diseases affecting humans are of animal origin, the need for better One Health research strategies and overdue solutions is imperative.

AB - INTRODUCTION: Although traditional patient-centered medical homes (PCMHs) are effective for patients with complex needs, it is unclear whether homeless tailored PCMHs work better for homeless veterans. We examined the impact of enrollment in a Veterans Health Administration (VHA) homeless-tailored PCMH on health services use, cost, and satisfaction compared with enrollment in a traditional, nontailored PCMH. METHODS: We conducted a prospective, multicenter, quasi-experimental, single-blinded study at 2 VHA medical centers to assess health services use, cost, and satisfaction during 12 months among 2 groups of homeless veterans: 1) veterans receiving VHA homeless-tailored primary care (Homeless-Patient Aligned Care Team [H-PACT]) and 2) veterans receiving traditional primary care services (PACT). A cohort of 266 homeless veterans enrolled from June 2012 through January 2014. RESULTS: Compared with PACT patients, H-PACT patients had more social work visits (4.6 vs 2.7 visits) and fewer emergency department (ED) visits for ambulatory care-sensitive conditions (0 vs 0.2 visits); a significantly smaller percentage of veterans in H-PACT were hospitalized (23.1% vs 35.4%) or had mental health-related ED visits (34.1% vs 47.6%). We found significant differences in primary care provider-specific visits (H-PACT, 5.1 vs PACT, 3.6 visits), mental health care visits (H-PACT, 8.8 vs PACT, 13.4 visits), 30-day prescription drug fills (H-PACT, 40.5 vs PACT, 58.8 fills), and use of group therapy (H-PACT, 40.1% vs PACT, 53.7%). Annual costs per patient were significantly higher in the PACT group than the H-PACT group ($37,415 vs $28,036). In logistic regression model of acute care use, assignment to the H-PACT model was protective as was rating health "good" or better. CONCLUSION: Homeless veterans enrolled in the population-tailored primary care approach used less acute care and costs were lower. Tailored-care models have implications for care coordination in the US Department of Veterans Affairs VA and community health systems.

AB - Most Americans consume more than the recommended daily level of sodium, and tools are needed to assess and improve food practices related to sodium. We describe how the Sodium Practices Assessment Tool (SPAT) was developed and used in 19 hospitals and senior meal facilities in upstate New York. Initial results identified opportunities for improvement in food preparation, presentation, and purchasing practices to reduce sodium consumption. Pre-post comparison results showed significant increases in the use of herbs, spices, unsalted butter, fruits and vegetables, and in the availability of lower-sodium foods. Food service sites can use SPAT to assess sodium practices, inform development of action plans, and measure change over time.

AB - The interfacial microcracks in the resin matrix composites are difficult to be detected and repaired. However, the self-healing concept provides opportunities to fabricate composites with unusual properties. In the present study, photothermal conversion Ag-Cu2S nanoparticles were immobilized onto poly(p phenylene benzobisoxazole) (PBO) fibers via a polydopamine chemistry. Benefitting from the photothermal effects of Ag-Cu2S, the obtained PBO fibers (Ag-Cu2S-PBO) efficiently converted the light energy into heat under Xenon lamp irradiation. Then, single PBO fiber composites were prepared using thermoplastic polyurethane as the matrix. It was found that the interfacial damage caused by single fiber pull-out was simply self-healed by Xe light irradiation. This wonderful interfacial damage self-healing property was mainly attributed to the in situ heating generation via photothermal effects of Ag-Cu2S in the composite interface. This paper reports a novel strategy to construct advanced composites with light-triggered self-healing properties, which will provide inspiration for preparing high performance composite materials. PMID- 29451118 TI - A spatial memory signal shows that the parietal cortex has access to a craniotopic representation of space. AB - Humans effortlessly establish a gist-like memory of their environment whenever they enter a new place, a memory that can guide action even in the absence of vision. Neurons in the lateral intraparietal area (LIP) of the monkey exhibit a form of this environmental memory. These neurons respond when a monkey makes a saccade that brings the spatial location of a stimulus that appeared on a number of prior trials, but not on the present trial, into their receptive fields (RFs). The stimulus need never have appeared in the neuron's RF. This memory response is usually weaker, with a longer latency than the neuron's visual response. We suggest that these results demonstrate that LIP has access to a supraretinal memory of space, which is activated when the spatial location of the vanished stimulus can be described by a retinotopic vector from the center of gaze to the remembered spatial location. PMID- 29451120 TI - An in silico framework to analyze the anisotropic shear wave mechanics in cardiac shear wave elastography. AB - Shear wave elastography (SWE) is a potential tool to non-invasively assess cardiac muscle stiffness. This study focused on the effect of the orthotropic material properties and mechanical loading on the performance of cardiac SWE, as it is known that these factors contribute to complex 3D anisotropic shear wave propagation. To investigate the specific impact of these complexities, we constructed a finite element model with an orthotropic material law subjected to different uniaxial stretches to simulate SWE in the stressed cardiac wall. Group and phase speed were analyzed in function of tissue thickness and virtual probe rotation angle. Tissue stretching increased the group and phase speed of the simulated shear wave, especially in the direction of the muscle fiber. As the model provided access to the true fiber orientation and material properties, we assessed the accuracy of two fiber orientation extraction methods based on SWE. We found a higher accuracy (but lower robustness) when extracting fiber orientations based on the location of maximal shear wave speed instead of the angle of the major axis of the ellipsoidal group speed surface. Both methods had a comparable performance for the center region of the cardiac wall, and performed less well towards the edges. Lastly, we also assessed the (theoretical) impact of pathology on shear wave physics and characterization in the model. It was found that SWE was able to detect changes in fiber orientation and material characteristics, potentially associated with cardiac pathologies such as myocardial fibrosis. Furthermore, the model showed clearly altered shear wave patterns for the fibrotic myocardium compared to the healthy myocardium, which forms an initial but promising outcome of this modeling study. PMID- 29451121 TI - Influences of Au ion radiation on microstructure and surface-enhanced Raman scattering of nanoporous copper. AB - In this work, effects of Au ion irradiation on microstructure and surface enhanced Raman scattering (SERS) performance of nanoporous copper (NPC) were investigated. It is found that the microstructure of NPC could be tailored by the ion irradiation dose, i.e., the pore size decreases while the ligament size significantly coarsens with the increase of the irradiation dose. In addition, the SERS enhancement for rhodamine 6G molecules was improved by Au ions irradiation at an appropriate dose. The underlying mechanism of the increase of SERS enhancement resulted from ion irradiation was discussed. Our findings could provide a new way to tune nanoporosity of nanoporous metals and improve their SERS performance. PMID- 29451122 TI - Sprouting angiogenesis in engineered pseudo islets. AB - Despite the recent achievements in cell-based therapies for curing type-1 diabetes (T1D), capillarization in beta (beta)-cell clusters is still a major roadblock as it is essential for long-term viability and function of beta-cells in vivo. In this research, we report sprouting angiogenesis in engineered pseudo islets (EPIs) made of mouse insulinoma betaTC3 cells and rat heart microvascular endothelial cells (RHMVECs). Upon culturing in three-dimensional (3D) constructs under angiogenic conditions, EPIs sprouted extensive capillaries into the surrounding matrix. Ultra-morphological analysis through histological sections also revealed presence of capillarization within EPIs. EPIs cultured in 3D constructs maintained their viability and functionality over time while non vascularized EPIs, without the presence of RHMVECs, could not retain their viability nor functionality. Here we demonstrate angiogenesis in engineered islets, where patient specific stem cell-derived human beta cells can be combined with microvascular endothelial cells in the near future for long-term graft survival in T1D patients. PMID- 29451123 TI - Analytical bond order potential for simulations of BeO 1D and 2D nanostructures and plasma-surface interactions. AB - An analytical interatomic bond order potential for the Be-O system is presented. The potential is fitted and compared to a large database of bulk BeO and point defect properties obtained using density functional theory. Its main applications include simulations of plasma-surface interactions involving oxygen or oxide layers on beryllium, as well as simulations of BeO nanotubes and nanosheets. We apply the potential in a study of oxygen irradiation of Be surfaces, and observe the early stages of an oxide layer forming on the Be surface. Predicted thermal and elastic properties of BeO nanotubes and nanosheets are simulated and compared with published ab initio data. PMID- 29451124 TI - Copper oxide loaded PLGA nanospheres: towards a multifunctional nanoscale platform for ultrasound-based imaging and therapy. AB - Copper oxide nanoparticles (CuO-NPs) are increasingly becoming the subject of investigation exploring their potential use for diagnostic and therapeutic purposes. Recent work has demonstrated their anticancer potential, as well as contrast agent capabilities for magnetic resonance imaging (MRI) and through transmission ultrasound. However, no capability of CuO-NPs has been demonstrated using conventional ultrasound systems, which, unlike the former, are widely deployed in the clinic. Furthermore, in spite of their potential as multifunctional nano-based materials for diagnosis and therapy, CuO-NPs have been delayed from further clinical application due to their inherent toxicity. Herein, we present the synthesis of a novel nanoscale system, composed of CuO-loaded PLGA nanospheres (CuO-PLGA-NS), and demonstrate its imaging detectability and augmented heating effect by therapeutic ultrasound. The CuO-PLGA-NS were prepared by a double emulsion (W/O/W) method with subsequent solvent evaporation. They were characterized as sphere-shaped, with size approximately 200 nm. Preliminary results showed that the viability of PANC-1, human pancreatic adenocarcinoma cells was not affected after 72 h exposure to CuO-PLGA-NS, implying that PLGA masks the toxic effects of CuO-NPs. A systematic ultrasound imaging evaluation of CuO-PLGA-NS, using a conventional system, was performed in vitro and ex vivo using poultry heart and liver, and also in vivo using mice, all yielding a significant contrast enhancement. In contrast to CuO-PLGA-NS, neither bare CuO NPs nor blank PLGA-NS possess these unique advantageous ultrasonic properties. Furthermore, CuO-PLGA-NS accelerated ultrasound-induced temperature elevation by more than 4 degrees C within 2 min. The heating efficiency (cumulative equivalent minutes at 43 degrees C) was increased approximately six-fold, demonstrating the potential for improved ultrasound ablation. In conclusion, CuO PLGA-NS constitute a versatile platform, potentially useful for combined imaging and therapeutic ultrasound-based procedures.

AB - OBJECTIVE: Emerging evidence shows that cognitive deficits in Alzheimer's disease (AD) are associated with disruptions in brain functional connectivity. Thus, the identification of alterations in AD functional networks has become a topic of increasing interest. However, to what extent AD induces disruption of the balance of local and global information processing in the human brain remains elusive. The main objective of this study is to explore the dynamic topological changes of AD networks in terms of brain network segregation and integration. APPROACH: We used electroencephalography (EEG) data recorded from 20 participants (10 AD patients and 10 healthy controls) during resting state. Functional brain networks were reconstructed using EEG source connectivity computed in different frequency bands. Graph theoretical analyses were performed assess differences between both groups. MAIN RESULTS: Results revealed that AD networks, compared to networks of age-matched healthy controls, are characterized by lower global information processing (integration) and higher local information processing (segregation). Results showed also significant correlation between the alterations in the AD patients' functional brain networks and their cognitive scores. SIGNIFICANCE: These findings may contribute to the development of EEG network-based test that could strengthen results obtained from currently-used neurophysiological tests in neurodegenerative diseases. PMID- 29451126 TI - Fabrication of ultrathin multilayered superomniphobic nanocoatings by liquid flame spray, atomic layer deposition, and silanization. AB - Superomniphobic, i.e. liquid-repellent, surfaces have been an interesting area of research during recent years due to their various potential applications. However, producing such surfaces, especially on hard and resilient substrates like stainless steel, still remains challenging. We present a stepwise fabrication process of a multilayered nanocoating on a stainless steel substrate, consisting of a nanoparticle layer, a nanofilm, and a layer of silane molecules. Liquid flame spray was used to deposit a TiO2 nanoparticle layer as the bottom layer for producing a suitable surface structure. The interstitial Al2O3 nanofilm, fabricated by atomic layer deposition (ALD), stabilized the nanoparticle layer, and the topmost fluorosilane layer lowered the surface energy of the coating for enhanced omniphobicity. The coating was characterized with field emission scanning electron microscopy, focused ion beam scanning electron microscopy, x-ray photoelectron spectroscopy, contact angle (CA) and sliding angle (SA) measurements, and microscratch testing. The widely recognized requirements for superrepellency, i.e. CA > 150 degrees and SA < 10 degrees , were achieved for deioinized water, diiodomethane, and ethylene glycol. The mechanical stability of the coating could be varied by tuning the thickness of the ALD layer at the expense of repellency. To our knowledge, this is the thinnest superomniphobic coating reported so far, with the average thickness of about 70 nm. PMID- 29451127 TI - One-step hydrothermal synthesis of three-dimensional porous Ni-Co sulfide/reduced graphene oxide composite with optimal incorporation of carbon nanotubes for high performance supercapacitors. AB - Three-dimensional (3D) porous Ni-Co sulfide/reduced graphene oxide composite with the appropriate incorporation of carbon nanotubes (NCS/rGO/CNT) was fabricated as a promising material for supercapacitor electrodes. It combined the high pseudo capacitance of Ni-Co sulfide as well as the large specific surface area and electrical double layer capacitance of reduced graphene oxide (rGO). Carbon nanotubes (CNTs) were incorporated to act as the spacer for hindering the restacking of rGO and to construct a conductive network for enhancing the electron transport. The 3D porous NCS/rGO/CNT composite was fabricated by a facile one-step hydrothermal process in which Ni-Co sulfide nanosheets were synthesized and graphene oxide was reduced simultaneously. It was shown that the capacitance and cyclic performance indeed could be effectively improved via the appropriate addition of CNTs. In addition, a flexible all-solid-state asymmetric supercapacitor based on the NCS/rGO/CNT electrode was fabricated and exhibited the same capacitive electrochemical performance under bending. Also, it could successfully turn on a light-emitting diode light, revealing its feasibility in practical application. All results demonstrated that the developed NCS/rGO/CNT composite has potential application in supercapacitors. PMID- 29451128 TI - Signal-amplifying nanoparticle/hydrogel hybrid microarray biosensor for metal enhanced fluorescence detection of organophosphorus compounds. AB - In this study, we developed an enzyme-based miniaturized fluorescence biosensor to detect paraoxon, one of the most well-known neurotoxic organophosphorus compounds. The biosensor was fabricated with poly(ethylene glycol) (PEG) hydrogel microarrays that entrapped acetylcholinesterase (AChE) and quantum dots (QDs) as fluorescence reporters. Metal-enhanced fluorescence (MEF) was utilized to amplify the fluorescence signal, which was achieved by decorating QDs on the surface of silica-coated silver nanoparticles (Ag@Silica). The MEF effects of Ag@Silica were optimized by tuning the thickness of the silica shells, and under the optimized conditions, the fluorescence intensity was shown to be increased 5 fold, compared with the system without MEF. PEG hydrogel microarray entrapping QD-decorated Ag@Silica and AChE was prepared via photopatterning process. The entrapped AChE hydrolyzed paraoxon to produce p-nitrophenol within the hydrogel microstructure, which subsequently quenched the fluorescence of the QDs on the surface of Ag@Silica. The MEF-assisted fluorescence detection resulted in a significant enhancement of paraoxon detection. The detection limit was approximately 1.0 * 10 10 M and 2.0 * 10-7 M for sensing with and without MEF, respectively. The successful integration of a hydrogel microarray system with a microfluidic system was demonstrated to be a potential application for the MEF-based micro-total analysis-system. PMID- 29451129 TI - Stress evolution of Ge nanocrystals in dielectric matrices. AB - Germanium nanocrystals (Ge NCs) embedded in single and multilayer silicon oxide and silicon nitride matrices have been synthesized using plasma enhanced chemical vapor deposition followed by conventional furnace annealing or rapid thermal processing in N2 ambient. Compositions of the films were determined by Rutherford backscattering spectrometry and x-ray photoelectron spectroscopy. The formation of NCs under suitable process conditions was observed with high resolution transmission electron microscope micrographs and Raman spectroscopy. Stress measurements were done using Raman shifts of the Ge optical phonon line at 300.7 cm-1. The effect of the embedding matrix and annealing methods on Ge NC formation were investigated. In addition to Ge NCs in single layer samples, the stress on Ge NCs in multilayer samples was also analyzed. Multilayers of Ge NCs in a silicon nitride matrix separated by dielectric buffer layers to control the size and density of NCs were fabricated. Multilayers consisted of SiN y :Ge ultrathin films sandwiched between either SiO2 or Si3N4 by the proper choice of buffer material. We demonstrated that it is possible to tune the stress state of Ge NCs from compressive to tensile, a desirable property for optoelectronic applications. We also observed that there is a correlation between the stress and the crystallization threshold in which the compressive stress enhances the crystallization, while the tensile stress suppresses the process. PMID- 29451130 TI - Intrinsic optical signal imaging of the blood volume changes is sufficient for mapping the resting state functional connectivity in the rodent cortex. AB - OBJECTIVE: Resting state functional connectivity (RSFC) allows the study of functional organization in normal and diseased brain by measuring the spontaneous brain activity generated under resting conditions. Intrinsic optical signal imaging (IOSI) based on multiple illumination wavelengths has been used successfully to compute RSFC maps in animal studies. The IOSI setup complexity would be greatly reduced if only a single wavelength can be used to obtain comparable RSFC maps. APPROACH: We used anesthetized mice and performed various comparisons between the RSFC maps based on single wavelength as well as oxy-, deoxy- and total hemoglobin concentration changes. MAIN RESULTS: The RSFC maps based on IOSI at a single wavelength selected for sensitivity to the blood volume changes are quantitatively comparable to the RSFC maps based on oxy- and total hemoglobin concentration changes obtained by the more complex IOSI setups. Moreover, RSFC maps do not require CCD cameras with very high frame acquisition rates, since our results demonstrate that they can be computed from the data obtained at frame rates as low as 5 Hz. SIGNIFICANCE: Our results will have general utility for guiding future RSFC studies based on IOSI and making decisions about the IOSI system designs. PMID- 29451131 TI - Enhancement of radiation tolerance in GaAs/AlGaAs core-shell and InP nanowires. AB - Radiation effects on semiconductor nanowires (NWs) have attracted the attention of the research community due to their potential applications in space and atomic fields. The effective implementation of NW devices in a radiation environment is a matter of concern. Here, the photoluminescence (PL) and time-resolved PL (TRPL) measurements were performed on both GaAs and InP NWs at room temperature before and after 1 MeV H+ irradiation with fluences ranging from 1 * 1011 to 5 * 1013 p cm-2. It is found that the degradation of lifetime is size-dependent, and typically the minority carrier lifetime damage coefficient is closely correlated with the material and NW diameter. Compared to GaAs and InP bulk material counterparts, the lifetime damage coefficient of NWs decreases by a factor of about one order of magnitude. After irradiation, GaAs NWs with a smaller diameter show a much lower lifetime damage coefficient while InP NWs show an increase in carrier radiative lifetime. The increased size-dependent radiation hardness is mainly attributed to the defect sink effect and/or the improvement of a room temperature dynamic annealing mechanism of the NWs. The InP NWs also showed higher radiation tolerance than GaAs NWs. PMID- 29451132 TI - Synthesis of photothermal nanocomposites and their application to antibacterial assays. AB - In this work, we report a novel gold nanorod (AuNR)-based nanocomposite that shows strong binding to bacterium and high antibacterial efficiency. The AuNRs were used as a photothermal material to transform near-infrared radiation (NIR) into heat. We selected poly (acrylic acid) to modify the surface of the AuNRs based on a simple self-assembly method. After conjugation of the bacterium binding molecule vancomycin, the nanocomposites were capable of efficiently gathering on the cell walls of bacteria. The nanocomposites exhibited a high bacterial inhibition capability owing to NIR-induced heat generation in situ. Therefore, the prepared photothermal nanocomposites show great potential for use in antibacterial assays. PMID- 29451133 TI - Polyamide 6-LiCl nanofibrous membrane as low-temperature regenerative desiccant with improved stability. AB - Polyamide 6-LiCl (PA 6-LiCl) electrospun nanofibrous membranes (NFMs) have been successfully prepared as novel solid desiccant materials. The PA 6 NFM with 20% LiCl mass ratio had a sorption capacity of 1.8 g g-1 at 25 degrees C and 95% relative humidity, which was 4 times more than that of silica gels. The desorption isobars of the NFMs indicated that over 85% of sorbed water in the NFMs can be desorbed at about 50 degrees C, and the low regeneration temperature made it promising as an energy-saving desiccant material. The experimental results manifested that the sorption/desorption kinetics of the NFMs better fit the pseudo-second order model. According to scanning electron microscope images and the cycle experiment, the NFMs were also found to possess notably improved stability against moisture and could be recycled with little degradation of performance, which confirmed the practicability of the new desiccant membranes. PMID- 29451134 TI - A new route to gold nanoflowers. AB - Catanionic vesicles spontaneously formed by mixing the anionic surfactant bis(2 ethylhexyl) sulfosuccinate sodium salt with the cationic surfactant cetyltrimethylammonium bromide were used as a reducing medium to produce gold clusters, which are embedded and well-ordered into the template phase. The gold clusters can be used as seeds in the growth process that follows by adding ascorbic acid as a mild reducing component. When the ascorbic acid was added very slowly in an ice bath round-edged gold nanoflowers were produced. When the same experiments were performed at room temperature in the presence of Ag+ ions, sharp edged nanoflowers could be synthesized. The mechanism of nanoparticle formation can be understood to be a non-diffusion-limited Ostwald ripening process of preordered gold nanoparticles embedded in catanionic vesicle fragments. Surface enhanced Raman scattering experiments show an excellent enhancement factor of 1.7 . 105 for the nanoflowers deposited on a silicon wafer. PMID- 29451135 TI - Proximity coupling in superconductor-graphene heterostructures. AB - This review discusses the electronic properties and the prospective research directions of superconductor-graphene heterostructures. The basic electronic properties of graphene are introduced to highlight the unique possibility of combining two seemingly unrelated physics, superconductivity and relativity. We then focus on graphene-based Josephson junctions, one of the most versatile superconducting quantum devices. The various theoretical methods that have been developed to describe graphene Josephson junctions are examined, together with their advantages and limitations, followed by a discussion on the advances in device fabrication and the relevant length scales. The phase-sensitive properties and phase-particle dynamics of graphene Josephson junctions are examined to provide an understanding of the underlying mechanisms of Josephson coupling via graphene. Thereafter, microscopic transport of correlated quasiparticles produced by Andreev reflections at superconducting interfaces and their phase-coherent behaviors are discussed. Quantum phase transitions studied with graphene as an electrostatically tunable 2D platform are reviewed. The interplay between proximity-induced superconductivity and the quantum-Hall phase is discussed as a possible route to study topological superconductivity and non-Abelian physics. Finally, a brief summary on the prospective future research directions is given. PMID- 29451136 TI - Optimization of photoelectrochemical performance in Pt-modified p-Cu2O/n-Cu2O nanocomposite. AB - As it is expected to be one of the most promising materials for utilizing solar energy, Cu2O has attracted considerable attention with respect to the achievement of solar energy conversion. Until now, the photocurrent densities of all planar structure of the Cu2O photocathode have not even come close to the theoretical value of -14.7 mA cm-2 due to the incompatible light absorption and charge carrier diffusion lengths. Here, we have fabricated p-n Cu2O homojunction nanocomposite by multiple steps of electrochemical deposition processing with the optimization of deposition periods. The p-Cu2O/n-Cu2O nanocomposite fabricated by optimized pH (4.9) and deposition time (4 min) exhibited double the photocurrent density of that of the bare p-Cu2O photocathode. And the highest photocurrent density of nanostructured p-n Cu2O nanorod homojunction photocathode with a p Cu2O blocking layer reached -10.0 mA cm-2 at 0 V versus the reversible hydrogen electrode under simulated AM 1.5G illumination (100 mW cm-2). PMID- 29451137 TI - Self-assembled PCBM bilayers on graphene and HOPG examined by AFM and STM. AB - In this work we report fabrication and characterization of phenyl-C61-butyric acid methyl ester (PCBM) bilayer structures on graphene and highly oriented pyrolytic graphite (HOPG). Through careful control of the PCBM solution concentration (from 0.1 to 2 mg ml-1) and the deposition conditions, we demonstrate that PCBM molecules self-assemble into bilayer structures on graphene and HOPG substrates. Interestingly, the PCBM bilayers are formed with two distinct heights on HOPG, but only one unique representative height on graphene. At elevated annealing temperatures, edge diffusion allows neighboring vacancies to merge into a more ordered structure. This is, to the best of our knowledge, the first experimental realization of PCBM bilayer structures on graphene. This work could provide valuable insight into fabrication of new hybrid, ordered structures for applications to organic solar cells.

PMID- 29451138 TI - Detection of Repair of the Zone of Calcified Cartilage with Osteoarthritis through Mesenchymal Stem Cells by Ultrashort Echo Time Magnetic Resonance Imaging. AB - Objective: Currently, magnetic resonance imaging (MRI) is the most commonly used imaging modality for observing the growth and development of mesenchymal stem cells (MSCs) after in vivo transplantation to treat osteoarthritis (OA). However, it is a challenge to accurately monitor the treatment effects of MSCs in the zone of calcified cartilage (ZCC) with OA. This is especially true in the physiological and biochemical views that are not accurately detected by MRI contrast agents. In contrast, ultrashort time echo (UTE) MRI has been shown to be sensitive to the presence of the ZCC, creating the potential for more effectively observing the repair of the ZCC in OA by MSCs. A special focus is given to the outlook of the use of UTE MRI to detect repair of the ZCC with OA through MSCs. The limitations of the current techniques for clinical applications and future directions are also discussed. Data Sources: Using the combined keywords: "osteoarthritis", "mesenchymal stem cells", "calcified cartilage", and "magnetic resonance imaging", the PubMed/MEDLINE literature search was conducted up to June 1, 2017. Study Selection: A total of 132 published articles were initially identified citations. Of the 132 articles, 48 articles were selected after further detailed review. This study referred to all the important English literature in full. Results: In contrast, UTE MRI has been shown to be sensitive to the presence of the ZCC, creating the potential for more effectively observing the repair of the ZCC in OA by MSCs. Conclusions: The current studies showed that the ZCC could be described in terms of its histomorphology and biochemistry by UTE MRI. We prospected that UTE MRI has been shown the potential for more effectively observing the repair of the ZCC in OA by MSCs in vivo.

PMID- 29451141 TI - Associations between Body Composition Indices and Metabolic Disorders in Chinese Adults: A Cross-Sectional Observational Study. AB - Background: Obesity induces dyslipidemia, hypertension, glucose intolerance, and inflammatory state, which results in atherogenic processes, diabetes, and cardiovascular disease. We usually use body composition indices, such as body mass index (BMI), body fat percentage (BFP), waist circumference-height ratio (WHtR), and waist-hip ratio (WHR) to reflect the obesity. The aim of this large population-based cross-sectional study was to investigate the associations between body composition indices and metabolic parameters in Chinese adults. Methods: A total of 12,018 Chinese adults were included. Body composition indices, such as BMI, BFP, WHtR, and WHR, and metabolic parameters, such as systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol (TC), triglyceride (TG), low-density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C), fasting blood glucose (FBG), 2 h postprandial blood glucose (2h PBG), glycosylated hemoglobin (HbA1c), fasting insulin (FINS), insulin resistance index (HOMA-IR), high-sensitivity C-reactive protein (hs-CRP), and white blood cell count (WBC), were measured and analyzed. All analyses were stratified by gender. Results: All body composition indices and metabolic parameters except 2h PBG differed significantly between males and females (all P < 0.001). BMI was positively associated with SBP, DBP, LDL-C, TC, TG, FBG, 2h PBG, HbA1c, FINS, HOMA-IR, hs-CRP, and WBC, and inversely associated with HDL-C; similar relationships were identified between the metabolic parameters and BFP, WHtR, and WHR. In the multivariate analysis, the odds of impaired glucose regulation, dyslipidemia, insulin resistance, and increased hs CRP were 1.36, 1.92, 3.44, and 1.27 times greater in the overweight group than those in the normal weight group, respectively, and 1.66, 3.26, 7.53, and 1.70 times greater in the obese group than those in the normal weight group, respectively. The odds of dyslipidemia and hs-CRP were 1.29 and 1.38 times greater in the BFP >=28.0% group than in the BFP <28.0% group, respectively. The odds of dyslipidemia, HOMA-IR, and hs-CRP were 1.55, 1.26, and 1.48 times greater in the WHtR >=0.96 group than in the WHtR <0.96 group, respectively. Among males, the odds of HOMA-IR were 1.46 times greater in the WHR >=0.54 group than in the WHR <0.54 group. Similar results were observed in females. Conclusions: This study identified positive associations between all evaluated body composition indices and metabolic parameters in Chinese adults. Among the body composition indices, BMI predicted four of the five evaluated metabolic disorders in both gender groups. PMID- 29451142 TI - Cost Analysis of Cervical Cancer Patients with Different Medical Payment Modes Based on Gamma Model within a Grade A Tertiary Hospital. AB - Background: Cervical cancer shows a growing incidence and medical cost in recent years that has increased severe financial pressure on patients and medical insurance institutions. This study aimed to investigate the medical economic characteristics of cervical cancer patients with different payment modes within a Grade A tertiary hospital to provide evidence and suggestions for inpatient cost control and to verify the application of Gamma model in medical cost analysis. Methods: The basic and cost information of cervical cancer cases within a Grade A tertiary hospital in the year 2011-2016 were collected. The Gamma model was adopted to analyze the differences in each cost item between medical insured patient and uninsured patients. Meanwhile, the marginal means of different cost items were calculated to estimate the influence of payment modes toward different medical cost items among cervical cancer patients in the study. Results:: A total of 1321 inpatients with cervical cancer between the 2011 and 2016 were collected through the medical records system. Of the 1321 cases, 65.9% accounted for medical insured patients and 34.1% were uninsured patients. The total inpatient medical expenditure of insured patients was RMB 29,509.1 Yuan and uninsured patients was RMB 22,114.3 Yuan, respectively. Payment modes, therapeutic options as well as the recurrence and metastasis of tumor toward the inpatient medical expenditures between the two groups were statistically significant. To the specifics, drug costs accounted for 37.7% and 33.8% of the total, surgery costs accounted for 21.5% and 25.5%, treatment costs accounted for 18.7% and 16.4%, whereas the costs of imaging and laboratory examinations accounted for 16.4% and 15.2% for the insured patient and uninsured patients, respectively. As the effects of covariates were controlled, the total hospitalization costs, drug costs, treatment costs as well as imaging and laboratory examination costs showed statistical significance. The total hospitalization costs, drug costs, treatment costs as well as imaging and laboratory examination costs of insured patient were 1.33, 1.42, 1.52, and 1.44 times of uninsured patients. Conclusions: The analysis of different payment modes toward the medical economic characteristics based on Gamma model is basically rational. Medical payment modes are having certain influence toward the hospitalization expenses of cervical cancer patients in an extent, as drug costs, treatment costs, and examination costs appear to be the main causes. PMID- 29451143 TI - Familial Nonmedullary Thyroid Carcinoma: A Retrospective Analysis of 117 Families. AB - Background: The first and most important step in characterizing familial nonmedullary thyroid carcinoma (NMTC) is to distinguish the true familial patients, which is the prerequisite for all accurate analyses. This study aimed to investigate whether patients from families with >=3 first-degree relatives affected with NMTC have different characteristics than patients from families with only two affected members, and to compare these patients with those with sporadic disease. Methods:: We analyzed the clinicopathological features and prognosis of 209 familial and 1120 sporadic cases of NMTC. Familial patients were further divided into two subgroups: families with two affected members and families with >=3 affected members. Results:: The familial group had a significantly higher risk of bilateral growth, multifocality, extrathyroidal extension, and lateral lymph node metastasis than the sporadic group (P < 0.05). These main features were also different between the group with >=3 affected members and the sporadic group. The only difference between the two affected members' group and the sporadic group was incidence of multifocality (P < 0.05). The probability of disease recurrence in patients from families with >=3 affected members was significantly higher than that in sporadic cases (14.46% vs. 5.27%; P = 0.001), while the probability in patients from families with two affected members was similar to that in sporadic patients (6.35% vs. 5.27%; P = 0.610). The Kaplan-Meier survival analysis showed a statistically significant difference in disease-free survival between the two subgroups (85.54% vs. 93.65%; P = 0.045). Conclusions:: Patients from families with >=3 members affected by NMTC have more aggressive features and a worse prognosis than those from families with only two affected members. Patients from families with >=3 affected first-degree relatives may be considered to have true familial NMTC. PMID- 29451144 TI - Moderate Dose of Trolox Preventing the Deleterious Effects of Wi-Fi Radiation on Spermatozoa In vitro through Reduction of Oxidative Stress Damage. AB - Background: The worsening of semen quality, due to the application of Wi-Fi, can be ameliorated by Vitamin E. This study aimed to demonstrate whether a moderate dose of trolox, a new Vitamin E, inhibits oxidative damage on sperms in vitro after exposure to Wi-Fi radiation. Methods: Each of the twenty qualified semen, gathered from June to October 2014 in eugenics clinic, was separated into four aliquots, including sham, Wi-Fi-exposed, Wi-Fi plus 5 mmol/L trolox, and Wi-Fi plus 10 mmol/L trolox groups. At 0 min, all baseline parameters of the 20 samples were measured in sequence. Reactive oxygen species, glutathione, and superoxide dismutase were evaluated in the four aliquots at 45 and 90 min, as were sperm DNA fragments, sperm mitochondrial potential, relative amplification of sperm mitochondrial DNA, sperm vitality, and progressive and immotility sperm. The parameters were analyzed by one-way analysis of variance and Tukey's posttest. Results: Among Wi-Fi plus 5 mmol/L trolox, Wi-Fi-exposed and Wi-Fi plus 10 mmol/L trolox groups, reactive oxygen species levels (45 min: 3.80 +/- 0.41 RLU.10-6.ml 1 vs. 7.50 +/- 0.35 RLU.10-6.ml-1 vs. 6.70 +/- 0.47 RLU.10-6.ml-1, P < 0.001; 90 min: 5.40 +/- 0.21 RLU.10-6.ml-1 vs. 10.10 +/- 0.31 RLU.10-6.ml-1 vs. 7.00 +/- 0.42 RLU.10-6.ml-1, P < 0.001, respectively), percentages of tail DNA (45 min: 16.8 +/- 2.0% vs. 31.9 +/- 2.5% vs. 61.3 +/- 1.6%, P < 0.001; 90 min: 19.7 +/- 1.5% vs. 73.7 +/- 1.3% vs. 73.1 +/- 1.1%, P < 0.001, respectively), 8-hydroxy-2' deoxyguanosine (45 min: 51.89 +/- 1.46 pg/ml vs. 104.89 +/- 2.19 pg/ml vs. 106.11 +/- 1.81 pg/ml , P = 0.012; 90 min: 79.96 +/- 1.73 pg/ml vs. 141.73 +/- 2.90 pg/ml vs. 139.06 +/- 2.79 pg/ml; P < 0.001), and percentages of immotility sperm (45 min: 27.7 +/- 2.7% vs. 41.7 +/- 2.2% vs. 41.7 +/- 2.5%; 90 min: 29.9 +/- 3.3% vs. 58.9 +/- 4.0% vs. 63.1 +/- 4.0%; all P < 0.001) were lowest, and glutathione peroxidase (45 min: 60.50 +/- 1.54 U/ml vs. 37.09 +/- 1.77 U/ml vs. 28.18 +/- 1.06 U/ml; 90 min: 44.61 +/- 1.23 U/ml vs. 16.86 +/- 0.93 U/ml vs. 29.94 +/- 1.56 U/ml; all P < 0.001), percentages of head DNA (45 min: 83.2 +/- 2.0% vs. 68.2 +/- 2.5% vs. 38.8 +/- 1.6%; 90 min: 80.3 +/- 1.5% vs. 26.3 +/- 1.3% vs. 26.9 +/- 1.1%; all P < 0.001), percentages of sperm vitality (45 min: 89.5 +/- 1.6% vs. 70.7 +/- 3.1% vs. 57.7 +/- 2.4%; 90 min: 80.8 +/- 2.2% vs. 40.4 +/- 4.0% vs. 34.7 +/- 3.9%; all P < 0.001), and progressive sperm (45 min: 69.3 +/- 2.7% vs. 55.8 +/- 2.2% vs. 55.4 +/- 2.5%; 90 min: 67.2 +/- 3.3% vs. 38.2 +/- 4.0% vs. 33.9 +/- 4.0%; all P < 0.001) were highest in Wi-Fi plus 5 mmol/L trolox group at 45 and 90 min, respectively. Other parameters were not affected, while the sham group maintained the baseline. Conclusion: This study found that 5 mmol/L trolox protected the Wi-Fi-exposed semen in vitro from the damage of electromagnetic radiation-induced oxidative stress. PMID- 29451145 TI - Patients Administered Neoadjuvant Chemotherapy Could be Enrolled into an Enhanced Recovery after Surgery Program for Locally Advanced Gastric Cancer. AB - Background: Most studies on enhanced recovery after surgery (ERAS) for gastric cancer exclude patients who received neoadjuvant chemotherapy. Here, we aimed to evaluate whether patients who received neoadjuvant chemotherapy can be enrolled into the ERAS program for locally advanced gastric cancer. Methods: From April 2015 to July 2017, 114 patients who received neoadjuvant chemotherapy for locally advanced gastric cancer were randomized into ERAS and standard care (SC) groups. Postoperative length of stay, complications, bowel function, and nutritional status were recorded. Results:: The postoperative length of stay of the ERAS group was shorter compared with that of the SC group (5.9 +/- 5.6 vs. 8.1 +/- 5.3 days, P = 0.037). The postoperative complication rate was 9.3% in the ERAS group and 11.5% in the SC group (P = 0.700). The time to first flatus (2.7 +/- 2.0 vs. 4.5 +/- 4.6 days, P = 0.010) and time to a semi-liquid diet (3.2 +/- 2.1 vs. 6.3 +/- 4.9 days, P < 0.001) in the ERAS group were shorter compared with those in the SC group. On the 10th day after surgery, the values of weight, total protein, albumin, and prealbumin of the ERAS group were lower compared with those of the SC group. Conclusions:: Patients who received neoadjuvant chemotherapy could be enrolled into ERAS programs for locally advanced gastric cancer. The nutritional status of these patients was not adversely affected. PMID- 29451146 TI - Safety and Efficiency of Trabectome-mediated Trabecular Meshwork Ablation for Chinese Glaucoma Patients: A Two-year, Retrospective, Multicentre Study. AB - Background: The aim of the study was to evaluate the long-term safety and efficacy of the Trabectome for Chinese glaucoma patients. Methods: This was a multicenter, retrospective, observational study. Glaucoma patients, except those with neovascular glaucoma, with/without a visually significant cataract were enrolled. The patients received Trabectome or a combined surgery with phacoemulsification and intraocular lens implantation. The primary outcome evaluation was a reduction in intraocular pressure (IOP), and the secondary outcomes were a reduction in glaucoma medication, the 2-year success percentages, and complications. Success was defined as an IOP <21 mmHg and at least a 20% IOP reduction from baseline after 3 months for any two consecutive visits, without additional glaucoma surgery. The data were processed using the R Stats Package version 3.0.0. The Wilcoxon test was used to compare the postoperative IOP and the number of glaucoma medications with baselines. The Kaplan-Meier test was used to calculate the 2-year success percentage. The risk factors related to Trabectome failure were determined by logistic regression. Results: A total of 120 glaucoma patients were enrolled. The Trabectome efficiently reduced the IOP from a baseline of 22.8 +/- 1.34 mmHg to 17.6 +/- 0.96 mmHg, and the use of glaucoma medications from 2.2 +/- 0.17 mmHg to 1.4 +/- 0.21 in a 2-year follow-up (both, P < 0.01). The overall success percentage was 80%. No risk factor related to Trabectome failure was identified. No vision-threatening complication was observed. Ten patients, who required secondary glaucoma surgery, all reached the target IOP. Conclusions: In a 2-year follow-up, Trabectome was an efficient and safe procedure for Chinese glaucoma patients. PMID- 29451147 TI - Perioperative Single-Donor Platelet Apheresis and Red Blood Cell Transfusion Impact on 90-Day and Overall Survival in Living Donor Liver Transplantation. AB - Background:: Although many previous studies have confirmed that perioperative blood transfusion is associated with poor outcomes after liver transplantation (LT), few studies described the influence of single-donor platelet apheresis transfusion in living donor LT (LDLT). This study aimed to assess the effect of blood products on outcomes for LDLT recipients, focusing on apheresis platelets. Methods:: This retrospective study included 126 recipients who underwent their first adult-to-adult LDLT. Twenty-four variables including consumption of blood products of 126 LDLT recipients were assessed for their link to short-term outcomes and overall survival. Kaplan-Meier survival curve and the log-rank test were used for recipient survival analysis. A multivariate Cox proportional-hazard model and a propensity score analysis were applied to adjust confounders after potential risk factors were identified by a univariate Cox analysis. Results: Patients who received apheresis platelet transfusion had a lower 90-day cumulative survival (78.9% vs. 94.2%, P = 0.009), but had no significant difference in overall survival in the Cox model, compared with those without apheresis platelet transfusion. Units of apheresis platelet transfusion (hazard ratio [HR] = 3.103, 95% confidence interval [CI]: 1.720-5.600, P < 0.001) and preoperative platelet count (HR = 0.170, 95% CI: 0.040-0.730, P = 0.017) impacted 90-day survival independently. Multivariate Cox regression analysis also found that units of red blood cell (RBC) transfusion (HR = 1.036, 95% CI: 1.006-1.067, P = 0.018), recipient's age (HR = 1.045, 95% CI: 1.005-1.086, P = 0.025), and ABO blood group comparison (HR = 2.990, 95% CI: 1.341-6.669, P = 0.007) were independent risk factors for overall survival after LDLT. Conclusions:: This study suggested that apheresis platelets were only associated with early mortality but had no impact on overall survival in LDLT. Units of RBC, recipient's age, and ABO group comparison were independent predictors of long term outcomes. PMID- 29451148 TI - Increased Endogenous Sulfur Dioxide Involved in the Pathogenesis of Postural Tachycardia Syndrome in Children: A Case-Control Study. AB - Background: The pathogenesis of postural tachycardia syndrome (POTS) remains unclear. This study aimed to explore the changes and significance of sulfur dioxide (SO2) in patients with POTS. Methods: The study included 31 children with POTS and 27 healthy children from Peking University First Hospital between December 2013 and October 2015. A detailed medical history, physical examination results, and demographic characteristics were collected. Hemodynamics was recorded and the plasma SO2was determined. Results: The plasma SO2was significantly higher in POTS children compared to healthy children (64.0 +/- 20.8 MUmol/L vs. 27.2 +/- 9.6 MUmol/L, respectively, P < 0.05). The symptom scores in POTS were positively correlated with plasma SO2levels (r = 0.398, P < 0.05). In all the study participants, the maximum heart rate (HR) was positively correlated with plasma levels of SO2(r = 0.679, P < 0.01). The change in systolic blood pressure from the supine to upright (DeltaSBP) in POTS group was smaller than that in the control group (P < 0.05). The DeltaSBP was negatively correlated with baseline plasma SO2levels in all participants (r = -0.28, P < 0.05). In the control group, DeltaSBP was positively correlated with the plasma levels of SO2(r = 0.487, P < 0.01). The change in HR from the supine to upright in POTS was obvious compared to that of the control group. The area under curve was 0.967 (95% confidence interval: 0.928-1.000), and the cutoff value of plasma SO2 level >38.17 MUmol/L yielded a sensitivity of 90.3% and a specificity of 92.6% for predicting the diagnosis of POTS. Conclusions: Increased endogenous SO2levels might be involved in the pathogenesis of POTS. PMID- 29451150 TI - Identification of Seven Novel Mutations in the Acid Alpha-glucosidase Gene in Five Chinese Patients with Late-onset Pompe Disease. AB - Background: Pompe disease is a rare lysosomal glycogen storage disorder linked to the acid alpha-glucosidase gene (GAA). A wide clinical and genetic variability exists between patients from different ethnic populations, and the genotype phenotype correlations are still not well understood. The aim of this study was to report the clinicopathological and genetic characteristics of five Chinese patients with late-onset Pompe disease (LOPD) who carried novel GAA gene mutations. Methods: Clinical and pathological data of patients diagnosed with glycogen storage disease at our institution from April 1986 to August 2017 were collected, and next-generation sequencing of frozen muscle specimens was conducted. Results: Of the five patients included in the study, the median disease onset age was 13 years, with a median 5 years delay in diagnosis. The patients mainly manifested as progressive weakness in the proximal and axial muscles, while one patient developed respiratory insufficiency that required artificial ventilation. In muscle biopsies, vacuoles with variable sizes and shapes appeared inside muscle fibers, and they stained positive for both periodic acid-Schiff and acid phosphatase staining. Ten GAA gene mutations, including seven novel ones (c.796C>A, c.1057C>T, c.1201C>A, c.1780C>T, c.1799G>C, c.2051C>A, c.2235dupG), were identified by genetic tests. Conclusions: The seven novel GAA gene mutations revealed in this study broaden the genetic spectrum of LOPD and highlight the genetic heterogeneity in Chinese LOPD patients. PMID- 29451149 TI - A Study on Clinical Characteristics and Magnetic Resonance Imaging Manifestations on Systemic Rosai-Dorfman Disease. AB - Background:: Rosai-Dorfman disease (RDD) is typically characterized by painless bilateral and symmetrical cervical lymphadenopathy, with associated fever and leukocytosis. The aim of the current study was to summarize the clinical features and imaging characteristics of RDD, in an effort to improve its diagnostic accuracy. Methods: The study was analyzed from 32 patients between January 2011 and December 2017; of these, 16 patients had pathologically diagnosed RDD, eight had pathologically diagnosed meningioma, and eight pathologically diagnosed lymphoma. All patients underwent computed tomography and magnetic resonance imaging (MRI). Clinical features and imaging characteristics of RDD were analyzed retrospectively. The mean apparent diffusion coefficient (ADC) values of lesions at different sites were measured, and one-way analysis of variance and the least significant difference t-test were used to compare the differences between groups and draw receiver operating characteristic curves. The tumors were excised for biopsy and analyzed using immunohistochemistry. Results:: The mean ADCs were (0.81 +/- 0.10) * 10-3 mm2/s for intercranial RDD, (0.73 +/- 0.05) * 10-3 mm2/s for nasopharyngeal RDD, (0.74 +/- 0.11) * 10-3 mm2/s for bone RDD, and (0.71 +/- 0.04) * 10-3 mm2/s for soft-tissue RDD. The optimum ADC to distinguish intracranial RDD from lymphoma was 0.79 * 10-3 mm2/s (62.5% sensitivity and 100% specificity) and to distinguish meningioma from intracranial RDD was 0.92 * 10-3 mm2/s (62.5% sensitivity and 100% specificity). Levels of C-reactive protein, erythrocyte sediment rate and D-dimer were significantly elevated (81%, 87%, and 75%, respectively). On immunohistochemistry, RDD was positive for both S-100 and CD68 proteins but negative for CD1a. Conclusions:: Conventional MRI, combined with diffusion-weighted imaging and ADC mapping, is an important diagnostic tool in evaluating RDD patients. An accurate diagnosis of RDD should consider the clinical features, imaging characteristics, and the pathological findings. PMID- 29451151 TI - Exosomal MicroRNA-10a Is Associated with Liver Regeneration in Rats through Downregulation of EphA4. AB - Background: MicroRNAs (miRNAs) have been reported to play vital roles in liver regeneration. Previous studies mainly focused on the functions of intracellular miRNAs, while the functions of circulating exosomal miRNAs in liver regeneration remain largely unknown. The aim of this study was to identify the key exosomal miRNA that played vital roles in liver regeneration. Methods: The Sprague-Dawley male rats were assigned to 70% partially hepatectomized group (n = 6) and sham surgery group (n = 6). The peripheral blood of both groups was collected 24 h after surgery. The exosomal miRNAs were extracted, and microarray was used to find out the key miRNA implicated in liver regeneration. Adenovirus was used to overexpress the key miRNA in rats, and proliferating cell nuclear antigen (PCNA) staining was applied to study the effect of key miRNA overexpression on liver regeneration. Western blotting was used to validate the predicted target of the key miRNA. Results: Exosomal miR-10a was upregulated more than nine times in hepatectomized rats. The level of miR-10a was increased in the early phase of liver regeneration, reached the top at 72 h postsurgery, and decreased to perioperative level 168 h after surgery. Moreover, enforced expression of miR-10a by adenovirus facilitated the process of liver regeneration as evidenced by immunohistochemical staining of PCNA. Erythropoietin-producing hepatocellular receptor A4 (EphA4) has been predicted to be a target of miR-10a. The protein level of EphA4 was decreased in the early phase of liver regeneration, reached the bottom at 72 h postsurgery, and rose to perioperative level 168 h after surgery, which was negatively correlated with miR-10a, confirming that EphA4 served as a downstream target of miR-10a. Moreover, inhibition of EphA4 by rhynchophylline could promote the proliferation of hepatocytes by regulating the cell cycle. Conclusion: Exosomal miR-10a might accelerate liver regeneration through downregulation of EphA4. PMID- 29451152 TI - Different Effects of Pravastatin on Preeclampsia-like Symptoms in Different Mouse Models. AB - Background: Pravastatin (Pra) exerts protective effects on preeclampsia. Preeclampsia is a multifactorial and pathogenic pathway syndrome. The present study compared the effects of Pra on clinical manifestations of preeclampsia in different pathogenic pathways. Methods: Two different preeclampsia-like mouse models used in this study were generated with Nomega-nitro-L-arginine methyl ester (L-NAME) and used lipopolysaccharide (LPS) from day 7 of gestation, respectively. Pra treatment was administered on day 2 after the models were established in each group (L-NAME + Pra, LPS + Pra, and Control + Pra, n = 8) or normal saline (NS) for the control group (L-NAME + NS, LPS + NS, and Control + NS, n = 8). Maternal weight, serum lipids, the histopathological changes, and lipid deposition in the liver and placenta were observed. The pregnancy outcomes were compared. The blood pressure analysis was carried out on repeated measurements of variance. Student's t-test was used for comparing the two groups. The enumeration data were compared by Chi-square test. Results: The mean arterial pressure (MAP) and 24-h urinary protein in the L-NAME + NS and LPS + NS groups were significantly higher than the Control + NS group (F = 211.05 and 309.92 for MAP, t = 6.63 and 8.63 for 24-h urinary protein; all P < 0.05) and reduced in the L-NAME + Pra group as compared to the L-NAME + NS group (F = 208.60 for MAP, t = 6.77 for urinary protein; both P < 0.05). Urinary protein was decreased in the LPS + Pra group as compared to the LPS + NS group (t = 5.33; P < 0.05), whereas MAP had no statistical significance (F = 3.37; P > 0.05). Compared to the Control + NS group, the placental efficiency in the L-NAME + NS and LPS + NS groups decreased significantly (t = 3.09 and 2.89, respectively; both P < 0.05); however, no significant difference was observed in L-NAME + Pra and LPS + Pra groups (t = 1.37 and 0.58, respectively; both P > 0.05). Free fatty acid was elevated in the L-NAME + NS group as compared to the Control + NS group (t = 3.99; P < 0.05) at day 18 of pregnancy and decreased in the L-NAME + Pra group as compared to the L-NAME + NS group (t = 3.28; P < 0.05); however, no significant change was observed in the LPS model (F = 0.32; P > 0.05). Conclusion: This study suggested that Pra affected the clinical manifestations differently in preeclampsia-like mouse models generated in various pathogenic pathways. PMID- 29451154 TI - Novel Mutations in SCN4A Gene Cause Myotonia Congenita with Scoliosis. PMID- 29451153 TI - Effects of Plasma Lipids and Statins on Cognitive Function. AB - Objective:: Dementia is the fourth most common cause of death in developed countries. The relationship between plasma lipids and cognitive function is complex and controversial. Due to the increasing life expectancy of the population, there is an urgent need to control vascular risk factors and to identify therapies to prevent and treat both cognitive impairment and dementia. Here, we reviewed the effects of plasma lipids and statins on cognitive function. Data Sources:: We searched the PubMed database for research articles published through November 2017 with key words including "plasma lipids," "hyperlipidemia," "hypercholesterolemia," "statins," and "cognition function." Study Selection:: Articles were retrieved and reviewed to analyze the effects of plasma lipids and statins on cognitive function and the mechanisms underlying these effects. Results:: Many studies have examined the relationship between plasma lipids and cognitive function, but no definitive conclusions can be drawn. The mechanisms involved may include blood-brain barrier injury, the influence on small blood vessels in the brain, the influence on amyloid deposition, and a neuroprotective effect. To date, most studies of statins and cognition have been observational, with few randomized controlled trials. Therefore, firm conclusions regarding whether mid- or long-term statin use affects cognition function and dementia remain elusive. However, increasing concern exists that statins may be a causative factor for cognitive problems. These adverse effects appear to be rare and likely represent a yet-to-be-defined vulnerability in susceptible individuals. Conclusions:: The association between plasma lipids and cognition, the mechanism of the influence of plasma lipids on cognitive function, and the association between statins and cognitive function are complex issues and currently not fully understood. Future research aimed at identifying the mechanisms that underlie the effects of plasma lipids and statins on cognition will not only provide important insight into the causes and interdependencies of cognitive impairment and dementia, but also inspire novel strategies for treating and preventing these cognitive disorders.

PMID- 29451166 TI - Molecular analysis of pancreatic cyst fluid changes clinical management. AB - Background and Objectives: DNA molecular analysis has been suggested as a tool to evaluate pancreatic cysts. This study assesses whether the addition of DNA molecular analysis alters clinical management. Methods: This is a retrospective review of 46 consecutive patients who underwent EUS-FNA of pancreatic cysts with DNA molecular analysis at two major academic institutions. Cases were presented to two pancreaticobiliary surgeons first without and then with DNA molecular analysis data. The primary outcome was the frequency with which clinical management was altered with the addition of DNA molecular analysis. Results: Forty-six patients with a mean age of 62.0 (+/-13.4) years and mean cyst size of 3.2 (+/-2.3) cm were included in the study. Cyst carcinoembryonic antigen (CEA) was available in 30 patients and ranged from 0.4 to 15,927 ng/mL. DNA molecular analysis was described as benign in 23 (50%), statistically indolent in 13 (28%), statistically higher risk in 9 (20%), and indeterminate in 1 (2%). Surgeon #1 changed the management in 13/46 cases (28%) and surgeon #2 changed the management in 12/46 cases (26%) with the addition of DNA molecular analysis. When organized by CEA concentration, those with an intermediate CEA (45-800 ng/mL) or without a CEA concentration had a management changed more frequently (40%) compared to all others (P < 0.05). Conclusions: The addition of DNA molecular analysis alters the clinical management of pancreatic cystic lesions most often when CEA levels are intermediate (45-800 ng/mL) or when no CEA concentration is available. Use of DNA molecular analysis can be considered in this cohort. Further study of molecular markers in pancreatic cystic lesions is recommended. PMID- 29451165 TI - EUS elastography: How to do it?

PMID- 29451167 TI - A Multicenter comparative trial of a novel EUS-guided core biopsy needle (SharkCoreTM) with the 22-gauge needle in patients with solid pancreatic mass lesions. AB - Background and Objectives: The ability to obtain adequate tissue of solid pancreatic lesions by EUS-guided remains a challenge. The aim of this study was to compare the performance characteristics and safety of EUS-FNA for evaluating solid pancreatic lesions using the standard 22-gauge needle versus a novel EUS biopsy needle. Methods: This was a multicenter retrospective study of EUS-guided sampling of solid pancreatic lesions between 2009 and 2015. Patients underwent EUS-guided sampling with a 22-gauge SharkCore (SC) needle or a standard 22-gauge FNA needle. Technical success, performance characteristics of EUS-FNA, the number of needle passes required to obtain a diagnosis, diagnostic accuracy, and complications were compared. Results: A total of 1088 patients (mean age = 66 years; 49% female) with pancreatic masses underwent EUS-guided sampling with a 22 gauge SC needle (n = 115) or a standard 22-gauge FNA needle (n = 973). Technical success was 100%. The frequency of obtaining an adequate cytology by EUS-FNA was similar when using the SC and the standard needle (94.1% vs. 92.7%, respectively). The sensitivity, specificity, and diagnostic accuracy of EUS-FNA for tissue diagnosis were not significantly different between two needles. Adequate sample collection leading to a definite diagnosis was achieved by the 1st, 2nd, and 3rd pass in 73%, 92%, and 98% of procedures using the SC needle and 20%, 37%, and 94% procedures using the standard needle (P < 0.001), respectively. The median number of passes to obtain a tissue diagnosis using the SC needle was significantly less as compared to the standard needle (1 and 3, respectively; P< 0.001). Conclusions: The EUS SC biopsy needle is safe and technically feasible for EUS-FNA of solid pancreatic mass lesions. Preliminary results suggest that the SC needle has a diagnostic yield similar to the standard EUS needle and significantly reduces the number of needle passes required to obtain a tissue diagnosis.

AB - Background and Objectives: Infected pancreatic necrosis (IPN) in the early phase is treated with "step up approach" involving initial percutaneous catheter drainage (PCD) followed by necrosectomy. There is a paucity of data on a combined approach of initial PCD followed by endoscopic drainage and necrosectomy. A retrospectively study on safety and efficacy of initial PCD followed by endoscopic transluminal drainage and necrosectomy in IPN. Methods: Retrospective analysis of data of 23 patients with IPN who were treated with a combined approach. Patients were divided into two groups as follows: patients with central necrosis in whom PCD and endoscopic drainage were done in the same collection (n = 11) and patients with combined central and peripheral necrosis where PCD was placed in peripheral necrosis, and endoscopic drainage was done for central necrosis (n = 12). Results: Endoscopic drainage could be done successfully in all 23 patients with mean time for the resolution being 4.0 +/- 0.9 weeks. Fifteen (65.2%) patients were successfully treated using multiple plastic stents while direct endoscopic necrosectomy (DEN) was needed in 8 (34.8%) patients and fully covered self-expanding metal stent was inserted in 6 (26%) patients. The number of endoscopic sessions needed were 3 in 3 (13%), 4 in 9 (39%) patients, 5 in 5 (22%), 6 in 3 (13%), and 7 in 3 (13%) patients, respectively. Patients of central walled-off pancreatic necrosis (WOPN) with PCD catheter in situ needed more endoscopic sessions for resolution as well as more frequently needed DEN in comparison to patients with central WOPN with no PCD catheter. Conclusion: The combined approach of initial PCD followed by endoscopic drainage and necrosectomy is safe and effective treatment alternative for patients with IPN.

AB - Background and Objectives: EUS-guided biliary drainage (EUS-BD) is a feasible procedure when ERCP fails, as is percutaneous transhepatic BD (PTBD). However, little is known about patient perception and preference of EUS-BD and PTBD. Patients and Methods: An international multicenter survey was conducted in seven tertiary referral centers. In total, 327 patients, scheduled to undergo ERCP for suspected malignant biliary obstruction, were enrolled in the study. Patients received decision aids with visual representation regarding the techniques, benefits, and adverse events (AEs) of EUS-BD and PTBD. Patients were then asked the choice between the two simulated scenarios (EUS-BD or PTBD) after failed ERCP, the reasons for their preference, and whether altering AE rates would influence their prior choice. Results: In total, 313 patients (95.7%) responded to the questionnaire and 251 patients (80.2%) preferred EUS-BD. The preference of EUS-BD was 85.7% (186/217) with EUS-BD expertise, compared to 67.7% (65/96) without EUS-BD expertise (P < 0.001). The main reason for choosing EUS-BD was the possibility of internal drainage (78.1%). In multivariate analysis, the availability of EUS-BD expertise was the single independent factor that influenced patient preference (odds ratio: 3.168; 95% of confidence interval, 1.714-5.856; P < 0.001). The preference of EUS-BD increased as AE rates decreased (P < 0.001). Conclusions: In this simulated scenario, approximately 80% of patients preferred EUS-BD over PTBD after failed ERCP. However, preference of EUS BD declined as its AE rates increased. Further technical innovations and improved proficiency in EUS-BD for reducing AEs may encourage the use of this procedure as a routine clinical practice when ERCP fails.

PMID- 29451170 TI - EUS-FNA using 22G nitinol or ProCore needles without on-site cytopathology. AB - Objectives: The project is aimed to compare the tissue sampling rate and the diagnostic accuracy rate of EUS-FNA using 22G nitinol and reverse bevel-tipped needles. Subjects and Methods: This was a prospective, randomized, crossover study in a tertiary academic hospital. All consecutive adult patients undergoing EUS-guided FNA for lesions > 2 cm were recruited. Patients fulfilling the inclusion and exclusion criteria underwent EUS-guided FNA using both needles in sequence. They were randomized on a 1:1 basis to determine whether EUS-FNA would be performed first using the 22G reverse bevel-tipped (ProCore) needle followed by the nitinol needle or vice versa. The patients and the pathologists were blinded to the type of needle used. Results: Forty patients with suspected malignant neoplasms were recruited to the study. No significant differences were found in the diagnostic yield (76.9% vs. 84.6%, P = 0.389), accuracy (71.8% vs. 84.6%, P = 0.170), sensitivity (77.8% vs. 86.1%, P = 0.358), specificity (100% vs. 100%, P = 1), positive predictive value (100% vs. 100%, P = 1), and negative predictive value (20.0% vs. 28.6%, P = 1). The percentage of obtained tissue for histological assessment was also similar (41.0% vs. 46.2%, P = 0.648). In terms of the quantity of tissue obtained with the needles, a larger proportion of patients in the nitinol group obtained more tissue for assessment (P = 0.003). Conclusion: The tissue-sampling rate and the diagnostic accuracy of the new 22G ProCore needle were comparable to the conventional 22G FNA needle in the absence of an on-site cytopathologist.

PMID- 29451178 TI - Involvement of epithelial-mesenchymal transition in liver fibrosis. AB - Fibrosis of the liver is an inherent wound healing response to chronic liver injury. Regeneration of liver epithelium and restoration of normal liver structure were generally involved in this process. Although the liver has a striking capacity to adapt to damage through tissue repair, excessive accumulation of extracellular matrix during this process often leads to scar tissue formation and subsequent fibrosis. Epithelial to mesenchymal transition (EMT) enables a polarized epithelial cell to undergo multiple changes biochemically and to bear a mesenchymal cell phenotype. EMT plays a critical role in tissue and organ development and embryogenesis. In the liver, it is proposed that epithelial cells can acquire fibroblastic phonotype via EMT and contribute to fibrogenesis. This made EMT a potential target for antifibrotic strategies. Following an original passion, many investigators devote themselves to exploring this mechanism in liver fibrosis. However, as research continues, this hypothesis became highly controversial. The exact contribution of EMT to fibrogenesis was challenged due to the contradictory results from related studies. In this review, we summarized the recent advances regarding EMT in hepatic fibrosis and discussed the potentially involved liver cell types and pathways in order to reach rational and helpful conclusions. PMID- 29451179 TI - Sarcopenia and risk of nonalcoholic fatty liver disease: A meta-analysis. AB - Background/Aim: The association between sarcopenia and nonalcoholic fatty liver disease (NAFLD) has been suggested by recent epidemiological studies, although the results have been inconsistent. This meta-analysis was conducted to summarize all available data and estimate the risk of NAFLD among patients with sarcopenia. Materials and Methods: A comprehensive literature review was conducted using MEDLINE and EMBASE databases through November 2016 to identify all studies that compared the risk of NAFLD among patients with sarcopenia versus those without sarcopenia. Effect estimates from each study were extracted and combined using the random-effect, generic inverse variance method of DerSimonian and Laird. Results: Five cross-sectional studies with 27,804 participants met the eligibility criteria and were included in the meta-analysis. The risk of NAFLD in patients with sarcopenia was significantly higher than those without sarcopenia with the pooled odds ratio of 1.54 (95% confidence interval, 1.05-2.26). The statistical heterogeneity was high with an I2of 83%. Conclusions: A significantly increased risk of NAFLD among patients with sarcopenia was observed in this study. PMID- 29451180 TI - Outcome of peroral endoscopic myotomy in achalasia cardia: Experience with a new triangular knife. AB - Background and Aim: Peroral endoscopic myotomy (POEM) is a technically demanding procedure. Recently, a new triangular knife with integrated water jet function (TTJ) has been introduced. The present study was aimed to analyze and compare the operating time, efficacy, and adverse events (AEs) between the conventional (TT knife) and new knife (TTJ). Patients and Methods: All patients with achalasia cardia (AC) who underwent POEM between August 2015 and November 2016 were analyzed retrospectively. Operating time (OT), technical success, and AEs were assessed and compared between TT and TTJ knife. Results: A total of 193 patients with AC underwent POEM during the specified period. Both groups had equivalent number of different subtypes of AC (I, II, and III). There was no difference in technical success between the two groups (TT, 99% vs TT, 98.9%). OT was significantly less in the TTJ group as compared to TT group (53.8 +/- 15.2 vs 66.26 +/- 19.2; P = 0.0001). On subanalysis, OT taken for submucosal tunneling was significantly less with TTJ knife (34.6 +/- 10.1 vs 45.83 +/- 14.80), whereas OT was similar for myotomy and clipping in both the groups. Significantly fewer use of coagulation forceps and exchanges of accessories were required in TTJ knife group (2.92 +/- 1.77 vs 10.5 +/- 3.58; P = 0.0001). There were no major AEs. Minor AEs were noted in 21.5% and 31% of patients in TTJ and TT knife groups, respectively. Conclusion: New triangular knife reduces procedure time and technical difficulty with POEM. POEM is an efficacious treatment for achalasia and can be safely executed in an endoscopy unit. PMID- 29451181 TI - The use of nonselective beta blockers is a risk factor for portal vein thrombosis in cirrhotic patients. AB - Background/Aim: A reduction in portal vein inflow velocity seems to predispose to the emergence of portal vein thrombosis (PVT). Nonselective beta-blockers (NSBBs), used to prevent variceal bleeding, may increase the development of PVT by reducing portal vein inflow velocity. In this retrospective case-control study, we evaluated the risk factors and clinical features of a first event of PVT in 130 cirrhotics, 19 (15%) with (PVT group) and 111 (85%) without PVT (non PVT group). Patients and Methods: Patient evaluation and NNBB treatment were carried out according to the AASLD guidelines. Results: PVT was prevalently partial (84%) and asymptomatic (84%). Patients with PVT were treated with different regimens, and resolution of thrombosis was observed in about 50% of the cases. In both groups, HCV was the most frequent cause of cirrhosis and Child Pugh score A was prevalent. Ascites and esophageal varices were more frequent in the PVT group (P = 0.05 and <0.000, respectively). Treatment with NSBBs was significantly more frequent in the PVT group than in the non-PVT group (P < 0.000). PVT was associated with higher prevalence of chronic renal disease (P = 0.002), higher PT impairment (P = 0.003) and lower AST and ALT (P = 0.000). At multivariate logistic regression analysis, history of esophageal varices (P = 0.007) and NSBB treatment (P = 0.0003) were independent risk factors significantly associated with PVT. Conclusions: Esophageal varices and NSBB treatment were independent risk factors of PVT. Larger studies should evaluate the risk between variceal bleeding and portal vein thrombosis of using NSBBs, particularly in the prevention of first bleeding in nonadvanced liver cirrhosis. PMID- 29451182 TI - Host genetic factors in predicting response status in chronic hepatitis B patients discontinuing nucleos(t)ide analogs. AB - Background/Aims: The optimal duration of nucleos(t)ide analogs (NAs) therapy in chronic hepatitis B (CHB) patients remains unsatisfactory. Previous studies have confirmed the important role of host genetic factors in determining the outcome of HBV infection. This study tries to determine the role of host genetic factors in predicting response status in CHB patients discontinuing NAs according to stringent cessation criteria. Patients and Methods: Participating patients came from a prospective NAs- discontinuation cohort since June 1999. Six single nucleotide polymorphisms (SNPs) were selected according to previous report. SNaPshot assay was used for DNA SNPs analyses. Results: Seventy-six CHB patients were enrolled in our study, of which 61 patients were HBeAg-positive and 15 patients were HBeAg-negative. rs1883832 in the Kozak sequence of CD40 displayed an AUROC of 0.778 in predicting response status in CHB patients with HBeAg seroconversion and a genotype of CT was associated with sustained response in this subpopulation. The diagnostic performance of combinative index (rs1883832, age, and HBsAg at discontinuation) seemed to be better than that of rs1883832, but no statistical difference was observed. rs1883832 was also evaluated as an independent factor for response status by multivariate logistic regression. For HBeAg-negative CHB patients, rs9277535 at HLA-DP presents a Spearman correlation coefficient of 0.582 (P = 0.023) with virological relapse after discontinuation of NAs. Conclusions: rs1883832 serves as a valuable predictive factor for CHB patients with HBeAg seroconversion. rs9277535 at HLA-DP might also be a valuable predictive factor for CHB patients with HBeAg-negative, however, further verifications are recommended due to study limitations. PMID- 29451183 TI - The Level of TWIST1 expression determines the response of colon cancer cells to mitogen-activated protein kinases inhibitors. AB - Background/Aim: Currently, it has been proposed that combination of 5 fluorouracil (5FU) with inhibitors of the mitogen-activated protein kinases (MAPKs) signaling pathway might enhance the efficacy of 5FU-based chemotherapy in colon cancer. Our study aimed to investigate an impact of TWIST1 silencing on the sensitivity of cancer cells to 5FU and selected MAPK inhibitors. Materials and Methods: The suppression of TWIST1 expression in human colon cancer HT29 and HCT116 cell lines was achieved by transduction with lentiviral vector carrying the TWIST1 silencing sequence (pLL3.7-sh TWIST1). The statistical calculation was performed with analysis of variance or Dunnett's test for comparison to control group. Paired Student's t-test was performed when two groups were analyzed. Results: Suppression of TWIST1 reduced the proliferation rate of colon cancer cells and enhanced their sensitivity to 5FU and MAPKs inhibitors. The sensitivity of HT29 cells to examined compounds was more dependent on TWIST1 expression level compared to HCT116 cells. The most noticeable effect of TWIST1 suppression on sensitivity of both colon cancer cell lines to combined treatment of 5FU and the MAPKs inhibitors was observed for inhibitors of p38alpha/beta and JNK1-3. We also noted that the suppression of TWIST1 significantly sensitized both cell lines to combined treatment of 5FU and Rac inhibitor. Conclusions: Our observations point to TWIST1 expression level as a marker of colon cancer sensitivity to combined treatment of 5FU and MAPKs inhibitors. PMID- 29451184 TI - The long-term outcomes of cirrhotic patients with pleural effusion. AB - Background/Aim: A pleural effusion is an abnormal collection of fluid in the pleural space and may cause related morbidity or mortality in cirrhotic patients. Currently, there are insufficient data to support the long-term prognosis for cirrhotic patients with pleural effusion. In this study, we investigated the short- and long-term effects of pleural effusion on mortality in cirrhotic patients and evaluated the benefit of liver transplantation in these patients. Patients and Methods: The National Health Insurance Database, derived from the Taiwan National Health Insurance Program, was used to identify 3,487 cirrhotic patients with pleural effusion requiring drainage between January 1, 2007 and December 31, 2010. The proportional hazards Cox regression model was used to control for possible confounding factors. Results: The 30-day, 90-day, 1-year, and 3-year mortalities were 20.1%, 40.2%, 59.1%, and 75.9%, respectively, in the cirrhotic patients with pleural effusion. After Cox proportional hazard regression analysis adjusted by patient gender, age, complications of cirrhosis and comorbid disorders, old age, esophageal variceal bleeding, hepatocellular carcinoma, hepatic encephalopathy, pneumonia, renal function impairment, and without liver transplantation conferred higher risks for 3-year mortality in the cirrhotic patients with pleura effusion. Liver transplantation is the most important factor to determine the 3-year mortalities (HR: 0.17, 95% CI 0.11- 0.26, P < 0.001). The 30-day, 30 to 90-day, 90-day to 1-year, and 1 to 3-year mortalities were 5.7%, 13.4%, 20.4%, and 21.7% respectively, in the liver transplantation group, and 20.5%, 41.0%, 61.2%, and 77.5%, respectively, in the non-liver transplantation group. Conclusion: In cirrhotic patients, the presence of pleural effusion predicts poor long-term outcomes. Liver transplantation could dramatically improve the survival and should be suggested as soon as possible. PMID- 29451185 TI - Early versus conventional stoma closure following bowel surgery: A randomized controlled trial. AB - Background/Aim: To compare early stoma closure with conventional stoma closure following defunctioning diversion stoma surgery with respect to the frequency of complications, health-related quality of life (QoL), and length of hospitalization (LoH). Patients and Methods: This study was designed as a prospective parallel-arm randomized controlled trial. Patients who underwent temporary stoma following bowel surgery between February 2014 and November 2015 were included. The rate of complications (medical and surgical) following early and conventional stoma closure was assessed. Health-related QoL and LoH were also measured. Results: One hundred patients were included, with 50 cases in each group. Postoperative complications including laparostoma (6% vs. 2%;P = 0.307), wound infection (32% vs. 18%; P = 0.106), intra-abdominal collection (14% vs. 18%; P = 0.585), anastomotic leak (4%vs. 8%;P = 0.400), and medical complications were comparable (22% vs. 32%;P = 0.257). The length of hospital stay, overall mortality and morbidity (64% vs. 44%; P = 0.05) were similar across the two groups. There was a significant reduction in the cost towards stoma care (96% vs. 2%; P = 0.001) in the early stoma closure group. Patients in the early stoma closure group also had a significantly better QoL. Conclusion: Early stoma closure does not carry an increased risk of postoperative complications, reduces cost towards stoma care, and leads to better a QoL. PMID- 29451186 TI - Lactobacillus acidophilus and Bifidobacterium longum supernatants upregulate the serotonin transporter expression in intestinal epithelial cells. AB - Background/Aims: Probiotics play a role in relieving irritable bowel syndrome (IBS); however, the underlying mechanism is yet unclear. The aim of the study was to investigate the effects of the supernatants of Lactobacillus acidophilus and Bifidobacterium longum on the expression of serotonin transporter (SERT) messenger ribonucleic acid (mRNA) and protein. Materials and Methods: HT-29 and Caco-2 cells were treated with different concentrations of L. acidophilus and B. longum supernatants for 12 h and 24 h, respectively. SERT mRNA and proteins levels were detected by real-time polymerase chain reaction (real-time PCR) and Western-blotting. Results: The mRNA levels of SERT in HT-29 and Caco-2 cells treated with different concentrations of L. acidophilus or B. longum supernatants for 12 h and 24 h, each, were higher than that in the control groups. In addition, the expression of the protein in both cells was also upregulated, which was approximately similar to that of the corresponding mRNA. Conclusions: L. acidophilus and B. longum supernatants can upregulate SERT mRNA and protein levels in intestinal epithelial cells.

Few types of cells have spurred as much interest and excitement as stem cells over the past few decades. The multipotentiality and self-renewing characteristics of stem cells confer upon them the capability to regenerate lost tissue in ischemic or degenerative conditions as well as trauma. While stem cells have not yet proven to be clinically effective in many such conditions as was once hoped, they have demonstrated some effects that could be manipulated for clinical benefit. The various types of stem cells have similar characteristics, and largely differ in terms of origin; those that have differentiated to some extent may exhibit limited capability in differentiation potential. Stem cells can aid in decreasing lesion size and improving function following brain injury. PMID- 29451200 TI - Modulation of mitochondrial bioenergetics as a therapeutic strategy in Alzheimer's disease. AB - Alzheimer's disease (AD) is an increasingly pressing worldwide public-health, social, political and economic concern. Despite significant investment in multiple traditional therapeutic strategies that have achieved success in preclinical models addressing the pathological hallmarks of the disease, these efforts have not translated into any effective disease-modifying therapies. This could be because interventions are being tested too late in the disease process. While existing therapies provide symptomatic and clinical benefit, they do not fully address the molecular abnormalities that occur in AD neurons. The pathophysiology of AD is complex; mitochondrial bioenergetic deficits and brain hypometabolism coupled with increased mitochondrial oxidative stress are antecedent and potentially play a causal role in the disease pathogenesis. Dysfunctional mitochondria accumulate from the combination of impaired mitophagy, which can also induce injurious inflammatory responses, and inadequate neuronal mitochondrial biogenesis. Altering the metabolic capacity of the brain by modulating/potentiating its mitochondrial bioenergetics may be a strategy for disease prevention and treatment. We present insights into the mechanisms of mitochondrial dysfunction in AD brain as well as an overview of emerging treatments with the potential to prevent, delay or reverse the neurodegenerative process by targeting mitochondria. PMID- 29451201 TI - Tackling dipeptidyl peptidase IV in neurological disorders. AB - Dipeptidyl peptidase IV (DPP-IV) is a serine protease best known for its role in inactivating glucagon-like peptide-1 (GLP-1), pituitary adenylate cyclase activating polypeptide (PACAP) and glucose-dependent insulinotropic peptide (GIP), three stimulators of pancreatic insulin secretion with beneficial effects on glucose disposal. Owing to the relationship between DPP-IV and these peptides, inhibition of DPP-IV enzyme activity is considered as an attractive treatment option for diabetic patients. Nonetheless, increasing studies support the idea that DPP-IV might also be involved in the development of neurological disorders with a neuroinflammatory component, potentially through its non-incretin activities on immune cells. In this review article, we aim at highlighting recent literature describing the therapeutic value of DPP-IV inhibitors for the treatment of such neurological conditions. Finally, we will illustrate some of the promising results obtained using berberine, a plant extract with potent inhibitory activity on DPP-IV. PMID- 29451202 TI - Stem cells for spinal cord injuries bearing translational potential. AB - Spinal cord injury (SCI) is a highly debilitating neurological disease, which still lacks effective treatment strategies, causing significant financial burden and distress to the affected families. Nevertheless, nanotechnology and regenerative medicine strategies holding promise for the development of novel therapies that would reach from bench to bedside to serve the SCI patients. There has already been significant progress in the field of cell-based therapies, with the clinical application for SCI, currently in phase II of the clinical trial. Stem cells (e.g., induced pluripotent stem cells, fetal stem cells, human embryonic stem cells, and olfactory ensheathing cells) are certainly not to be considered the panacea for neural repair but, especially when combined with rehabilitation or other combinatorial approaches using the help of nanotechnology, they seem to be the source of some of the most promising and clinical translatable cell-based therapies that could help solving impactful problems on neural repair. PMID- 29451204 TI - Conundrums and confusions regarding how polyethylene glycol-fusion produces excellent behavioral recovery after peripheral nerve injuries. AB - Current Neuroscience dogma holds that transections or ablations of a segment of peripheral nerves produce: (1) Immediate loss of axonal continuity, sensory signaling, and motor control; (2) Wallerian rapid (1-3 days) degeneration of severed distal axons, muscle atrophy, and poor behavioral recovery after many months (if ever, after ablations) by slowly-regenerating (1 mm/d), proximal-stump outgrowths that must specifically reinnervate denervated targets; (3) Poor acceptance of microsutured nerve allografts, even if tissue-matched and immune suppressed. Repair of transections/ablations by neurorrhaphy and well-specified sequences of PEG-fusion solutions (one containing polyethylene glycol, PEG) successfully address these problems. However, conundrums and confusions regarding unorthodox and dramatic results of PEG-fusion repair in animal model systems often lead to misunderstandings. For example, (1) Axonal continuity and signaling is re-established within minutes by non-specifically PEG-fusing (connecting) severed motor and sensory axons across each lesion site, but remarkable behavioral recovery to near-unoperated levels takes several weeks; (2) Many distal stumps of inappropriately-reconnected, PEG-fused axons do not ever (Wallerian) degenerate and continuously innervate muscle fibers that undergo much less atrophy than otherwise-denervated muscle fibers; (3) Host rats do not reject PEG-fused donor nerve allografts in a non-immuno-privileged environment with no tissue matching or immunosuppression; (4) PEG fuses apposed open axonal ends or seals each shut (thereby preventing PEG-fusion), depending on the experimental protocol; (5) PEG-fusion protocols produce similar results in animal model systems and early human case studies. Hence, iconoclastic PEG-fusion data appropriately understood might provoke a re-thinking of some Neuroscience dogma and a paradigm shift in clinical treatment of peripheral nerve injuries. PMID- 29451203 TI - A growing field: The regulation of axonal regeneration by Wnt signaling. AB - The canonical Wnt/beta-catenin pathway is a highly conserved signaling cascade that plays critical roles during embryogenesis. Wnt ligands regulate axonal extension, growth cone guidance and synaptogenesis throughout the developing central nervous system (CNS). Recently, studies in mammalian and fish model systems have demonstrated that Wnt/beta-catenin signaling also promotes axonal regeneration in the adult optic nerve and spinal cord after injury, raising the possibility that Wnt could be developed as a therapeutic strategy. In this review, we summarize experimental evidence that reveals novel roles for Wnt signaling in the injured CNS, and discuss possible mechanisms by which Wnt ligands could overcome molecular barriers inhibiting axonal growth to promote regeneration. A central challenge in the neuroscience field is developing therapeutic strategies that induce robust axonal regeneration. Although adult axons have the capacity to respond to axonal guidance molecules after injury, there are several major obstacles for axonal growth, including extensive neuronal death, glial scars at the injury site, and lack of axonal guidance signals. Research in rodents demonstrated that activation of Wnt/beta-catenin signaling in retinal neurons and radial glia induced neuronal survival and axonal growth, but that activation within reactive glia at the injury site promoted proliferation and glial scar formation. Studies in zebrafish spinal cord injury models confirm an axonal regenerative role for Wnt/beta-catenin signaling and identified the cell types responsible. Additionally, in vitro and in vivo studies demonstrated that Wnt induces axonal and neurite growth through transcription-dependent effects of its central mediator beta-catenin, potentially by inducing regeneration-promoting genes. Canonical Wnt signaling may also function through transcription-independent interactions of beta-catenin with cytoskeletal elements, which could stabilize growing axons and control growth cone movement. Therefore, these studies suggest that Wnt-induced pathways responsible for regulating axonal growth during embryogenesis could be repurposed to promote axonal growth after injury.

AB - Numerous clinical and research applications necessitate the ability to interface with peripheral nerve fibers to read and control relevant neural pathways. Visceral organ modulation and rehabilitative prosthesis are two areas which could benefit greatly from improved neural interfacing approaches. Therapeutic neural interfacing, or 'bioelectronic medicine', has potential to affect a broad range of disorders given that all the major organs of the viscera are neurally innervated. However, a better understanding of the neural pathways that underlie function and a means to precisely interface with these fibers are required. Existing peripheral nerve interfaces, consisting primarily of electrode-based designs, are unsuited for highly specific (individual axon) communication and/or are invasive to the tissue. Our laboratory has explored an optogenetic approach by which optically sensitive reporters and actuators are targeted to specific cell (axon) types. The nature of such an approach is laid out in this short perspective, along with associated technologies and challenges.

AB - Fluid-attenuated inversion recovery (FLAIR) vascular hyperintensity (FVH) is used to assess leptomeningeal collateral circulation, but clinical outcomes of patients with FVH can be very different. The aim of the present study was to assess a FVH score and explore its relationship with clinical outcomes. Patients with acute ischemic stroke due to middle cerebral artery M1 occlusion underwent magnetic resonance imaging and were followed up at 10 days (National Institutes of Health Stroke Scale) and 90 days (modified Rankin Scale) to determine short term clinical outcomes. Effective collateral circulation indirectly improved recovery of neurological function and short-term clinical outcome by extending the size of the pial penumbra and reducing infarct lesions. FVH score showed no correlation with 90-day functional clinical outcome and was not sufficient as an independent predictor of short-term clinical outcome. PMID- 29451210 TI - Intravenous morphine self-administration alters accumbal microRNA profiles in the mouse brain. AB - A significant amount of evidence indicates that microRNAs (miRNAs) play an important role in drug addiction. The nucleus accumbens (NAc) is a critical part of the brain's reward circuit and is involved in a variety of psychiatric disorders, including depression, anxiety, and drug addiction. However, few studies have examined the expression of miRNAs and their functional roles in the NAc under conditions of morphine addiction. In this study, mice were intravenously infused with morphine (0.01, 0.03, 0.3, 1 and 3 mg/kg/infusion) and showed inverted U-shaped response. After morphine self-administration, NAc was used to analyze the functional networks of altered miRNAs and their putative target mRNAs in the NAc following intravenous self-administration of morphine. We utilized several bioinformatics tools, including Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway mapping and CyTargetLinker. We found that 62 miRNAs were altered and exhibited differential expression patterns. The putative targets were related to diverse regulatory functions, such as neurogenesis, neurodegeneration, and synaptic plasticity, as well as the pharmacological effects of morphine (receptor internalization/endocytosis). The present findings provide novel insights into the regulatory mechanisms of accumbal molecules under conditions of morphine addiction and identify several novel biomarkers associated with morphine addiction.

AB - Electroacupuncture preconditioning at acupoint Baihui (GV20) can reduce focal cerebral ischemia/reperfusion injury. However, the precise protective mechanism remains unknown. Mitochondrial fission mediated by dynamin-related protein 1 (Drp1) can trigger neuronal apoptosis following cerebral ischemia/reperfusion injury. Herein, we examined the hypothesis that electroacupuncture pretreatment can regulate Drp1, and thus inhibit mitochondrial fission to provide cerebral protection. Rat models of focal cerebral ischemia/reperfusion injury were established by middle cerebral artery occlusion at 24 hours after 5 consecutive days of preconditioning with electroacupuncture at GV20 (depth 2 mm, intensity 1 mA, frequency 2/15 Hz, for 30 minutes, once a day). Neurological function was assessed using the Longa neurological deficit score. Pathological changes in the ischemic penumbra on the injury side were assessed by hematoxylin-eosin staining. Cellular apoptosis in the ischemic penumbra on the injury side was assessed by terminal deoxyribonucleotidyl transferase-mediated dUTP-digoxigenin nick end labeling staining. Mitochondrial ultrastructure in the ischemic penumbra on the injury side was assessed by transmission electron microscopy. Drp1 and cytochrome c expression in the ischemic penumbra on the injury side were assessed by western blot assay. Results showed that electroacupuncture preconditioning decreased expression of total and mitochondrial Drp1, decreased expression of total and cytosolic cytochrome c, maintained mitochondrial morphology and reduced the proportion of apoptotic cells in the ischemic penumbra on the injury side, with associated improvements in neurological function. These data suggest that electroacupuncture preconditioning-induced neuronal protection involves inhibition of the expression and translocation of Drp1. PMID- 29451212 TI - Is it necessary to use the entire root as a donor when transferring contralateral C7 nerve to repair median nerve? AB - If a partial contralateral C7 nerve is transferred to a recipient injured nerve, results are not satisfactory. However, if an entire contralateral C7 nerve is used to repair two nerves, both recipient nerves show good recovery. These findings seem contradictory, as the above two methods use the same donor nerve, only the cutting method of the contralateral C7 nerve is different. To verify whether this can actually result in different repair effects, we divided rats with right total brachial plexus injury into three groups. In the entire root group, the entire contralateral C7 root was transected and transferred to the median nerve of the affected limb. In the posterior division group, only the posterior division of the contralateral C7 root was transected and transferred to the median nerve. In the entire root + posterior division group, the entire contralateral C7 root was transected but only the posterior division was transferred to the median nerve. After neurectomy, the median nerve was repaired on the affected side in the three groups. At 8, 12, and 16 weeks postoperatively, electrophysiological examination showed that maximum amplitude, latency, muscle tetanic contraction force, and muscle fiber cross-sectional area of the flexor digitorum superficialis muscle were significantly better in the entire root and entire root + posterior division groups than in the posterior division group. No significant difference was found between the entire root and entire root + posterior division groups. Counts of myelinated axons in the median nerve were greater in the entire root group than in the entire root + posterior division group, which were greater than the posterior division group. We conclude that for the same recipient nerve, harvesting of the entire contralateral C7 root achieved significantly better recovery than partial harvesting, even if only part of the entire root was used for transfer. This result indicates that the entire root should be used as a donor when transferring contralateral C7 nerve. PMID- 29451213 TI - Bone marrow-derived mesenchymal stem cells versus adipose-derived mesenchymal stem cells for peripheral nerve regeneration. AB - Studies have confirmed that bone marrow-derived mesenchymal stem cells (MSCs) can be used for treatment of several nervous system diseases. However, isolation of bone marrow-derived MSCs (BMSCs) is an invasive and painful process and the yield is very low. Therefore, there is a need to search for other alterative stem cell sources. Adipose-derived MSCs (ADSCs) have phenotypic and gene expression profiles similar to those of BMSCs. The production of ADSCs is greater than that of BMSCs, and ADSCs proliferate faster than BMSCs. To compare the effects of venous grafts containing BMSCs or ADSCs on sciatic nerve injury, in this study, rats were randomly divided into four groups: sham (only sciatic nerve exposed), Matrigel (MG; sciatic nerve injury + intravenous transplantation of MG vehicle), ADSCs (sciatic nerve injury + intravenous MG containing ADSCs), and BMSCs (sciatic nerve injury + intravenous MG containing BMSCs) groups. Sciatic functional index was calculated to evaluate the function of injured sciatic nerve. Morphologic characteristics of nerves distal to the lesion were observed by toluidine blue staining. Spinal motor neurons labeled with Fluoro-Gold were quantitatively assessed. Compared with sham-operated rats, sciatic functional index was lower, the density of small-diameter fibers was significantly increased, and the number of motor neurons significantly decreased in rats with sciatic nerve injury. Neither ADSCs nor BMSCs significantly improved the sciatic nerve function of rats with sciatic nerve injury, increased fiber density, fiber diameters, axonal diameters, myelin sheath thickness, and G ratios (axonal diameter/fiber diameter ratios) in the sciatic nerve distal to the lesion site. There was no significant difference in the number of spinal motor neurons among ADSCs, BMSCs and MG groups. These results suggest that neither BMSCs nor ADSCs provide satisfactory results for peripheral nerve repair when using MG as the conductor for engraftment. PMID- 29451214 TI - Optimization of micropatterned poly(lactic-co-glycolic acid) films for enhancing dorsal root ganglion cell orientation and extension. AB - Nerve conduits have been a viable alternative to the 'gold standard' autograft for treating small peripheral nerve gap injuries. However, they often produce inadequate functional recovery outcomes and are ineffective in large gap injuries. Ridge/groove surface micropatterning has been shown to promote neural cell orientation and guide growth. However, optimization of the ratio of ridge/groove parameters to promote orientation and extension for dorsal root ganglion (DRG) cells on poly(lactic-co-glycolic acid) (PLGA) films has not been previously conducted. Photolithography and micro-molding were used to define various combinations of ridge/groove dimensions on PLGA films. The DRG cells obtained from chicken embryos were cultured on micropatterned PLGA films for cell orientation and migration evaluation. Biodegradation of the films occurred during the test period, however, this did not cause deformation or distortion of the micropatterns. Results from the DRG cell orientation test suggest that when the ridge/groove ratio equals 1 (ridge/groove width parameters are equal, i.e., 10 MUm/10 MUm (even)), the degree of alignment depends on the size of the ridges and grooves, when the ratio is smaller than 1 (groove controlled) the alignment increases as the ridge size decreases, and when the ratio is larger than 1 (ridge controlled), the alignment is reduced as the width of the grooves decreases. The migration rate and neurite extension of DRG neurons were greatest on 10 MUm/10 MUm and 30 MUm/30 MUm micropatterned PLGA films. Based on the data, the 10 MUm/10 MUm and 30 MUm/30 MUm micropatterned PLGA films are the optimized ridge/groove surface patterns for the construction of nerve repair devices. PMID- 29451215 TI - Effect of moxibustion on mTOR-mediated autophagy in rotenone-induced Parkinson's disease model rats. AB - Defects in autophagy-mediated clearance of alpha-synuclein may be one of the key factors leading to progressive loss of dopaminergic neurons in the substantia nigra. Moxibustion therapy for Parkinson's disease has been shown to have a positive effect, but the underlying mechanism remains unknown. Based on this, we explored whether moxibustion could protect dopaminergic neurons by promoting autophagy mediated by mammalian target of rapamycin (mTOR), with subsequent elimination of alpha-syn. A Parkinson's disease model was induced in rats by subcutaneous injection of rotenone at the back of their necks, and they received moxibustion at Zusanli (ST36), Guanyuan (CV4) and Fengfu (GV16), for 10 minutes at every point, once per day, for 14 consecutive days. Model rats without any treatment were used as a sham control. Compared with the Parkinson's disease group, the moxibustion group showed significantly greater tyrosine hydroxylase immunoreactivity and expression of light chain 3-II protein in the substantia nigra, and their behavioral score, alpha-synuclein immunoreactivity, the expression of phosphorylated mTOR and phosphorylated ribosomal protein S6 kinase (p-p70S6K) in the substantia nigra were significantly lower. These results suggest that moxibustion can promote the autophagic clearance of alpha-syn and improve behavioral performance in Parkinson's disease model rats. The protective mechanism may be associated with suppression of the mTOR/p70S6K pathway. PMID- 29451216 TI - Does combined therapy of curcumin and epigallocatechin gallate have a synergistic neuroprotective effect against spinal cord injury? AB - Systematic inflammatory response after spinal cord injury (SCI) is one of the factors leading to lesion development and a profound degree of functional loss. Anti-inflammatory compounds, such as curcumin and epigallocatechin gallate (EGCG) are known for their neuroprotective effects. In this study, we investigated the effect of combined therapy of curcumin and EGCG in a rat model of acute SCI induced by balloon compression. Immediately after SCI, rats received curcumin, EGCG, curcumin + EGCG or saline [daily intraperitoneal doses (curcumin, 6 mg/kg; EGCG 17 mg/kg)] and weekly intramuscular doses (curcumin, 60 mg/kg; EGCG 17 mg/kg)] for 28 days. Rats were evaluated using behavioral tests (the Basso, Beattie, and Bresnahan (BBB) open-field locomotor test, flat beam test). Spinal cord tissue was analyzed using histological methods (Luxol Blue-cresyl violet staining) and immunohistochemistry (anti-glial fibrillary acidic protein, anti growth associated protein 43). Cytokine levels (interleukin-1beta, interleukin-4, interleukin-2, interleukin-6, macrophage inflammatory protein 1-alpha, and RANTES) were measured using Luminex assay. Quantitative polymerase chain reaction was performed to determine the relative expression of genes (Sort1, Fgf2, Irf5, Mrc1, Olig2, Casp3, Gap43, Gfap, Vegf, NfkappaB, Cntf) related to regenerative processes in injured spinal cord. We found that all treatments displayed significant behavioral recovery, with no obvious synergistic effect after combined therapy of curcumin and ECGC. Curcumin and EGCG alone or in combination increased axonal sprouting, decreased glial scar formation, and altered the levels of macrophage inflammatory protein 1-alpha, interleukin-1beta, interleukin 4 and interleukin-6 cytokines. These results imply that although the expected synergistic response of this combined therapy was less obvious, aspects of tissue regeneration and immune responses in severe SCI were evident. PMID- 29451217 TI - Neuroprotective mechanisms of rutin for spinal cord injury through anti-oxidation and anti-inflammation and inhibition of p38 mitogen activated protein kinase pathway. AB - Rutin has anti-inflammatory, antioxidant, anti-viral, anti-tumor and immune regulatory effects. However, the neuroprotective effects of rutin in spinal cord injury are unknown. The p38 mitogen activated protein kinase (p38 MAPK) pathway is the most important member of the MAPK family that controls inflammation. We assumed that the mechanism of rutin in the repair of spinal cord injury is associated with the inhibition of p38 MAPK pathway. Allen's method was used to establish a rat model of spinal cord injury. The rat model was intraperitoneally injected with rutin (30 mg/kg) for 3 days. After treatment with rutin, Basso, Beattie and Bresnahan locomotor function scores increased. Water content, tumor necrosis factor alpha, interleukin 1 beta, and interleukin 6 levels, p38 MAPK protein expression and caspase-3 and -9 activities in T8-9 spinal cord decreased. Oxidative stress related markers superoxide dismutase and glutathione peroxidase levels increased in peripheral blood. Rutin exerts neuroprotective effect through anti-oxidation, anti-inflammation, anti-apoptosis and inhibition of p38 MAPK pathway. PMID- 29451218 TI - PTEN knockdown with the Y444F mutant AAV2 vector promotes axonal regeneration in the adult optic nerve. AB - The lack of axonal regeneration is the major cause of vision loss after optic nerve injury in adult mammals. Activating the PI3K/AKT/mTOR signaling pathway has been shown to enhance the intrinsic growth capacity of neurons and to facilitate axonal regeneration in the central nervous system after injury. The deletion of the mTOR negative regulator phosphatase and tensin homolog (PTEN) enhances regeneration of adult corticospinal neurons and ganglion cells. In the present study, we used a tyrosine-mutated (Y444F) AAV2 vector to efficiently express a short hairpin RNA (shRNA) for silencing PTEN expression in retinal ganglion cells. We evaluated cell survival and axonal regeneration in a rat model of optic nerve axotomy. The rats received an intravitreal injection of wildtype AAV2 or Y444F mutant AAV2 (both carrying shRNA to PTEN) 4 weeks before optic nerve axotomy. Compared with the wildtype AAV2 vector, the Y444F mutant AAV2 vector enhanced retinal ganglia cell survival and stimulated axonal regeneration to a greater extent 6 weeks after axotomy. Moreover, post-axotomy injection of the Y444F AAV2 vector expressing the shRNA to PTEN rescued ~19% of retinal ganglion cells and induced axons to regenerate near to the optic chiasm. Taken together, our results demonstrate that PTEN knockdown with the Y444F AAV2 vector promotes retinal ganglion cell survival and stimulates long-distance axonal regeneration after optic nerve axotomy. Therefore, the Y444F AAV2 vector might be a promising gene therapy tool for treating optic nerve injury.

PMID- 29451219 TI - Low-frequency pulsed electromagnetic field pretreated bone marrow-derived mesenchymal stem cells promote the regeneration of crush-injured rat mental nerve. AB - Bone marrow-derived mesenchymal stem cells (BMSCs) have been shown to promote the regeneration of injured peripheral nerves. Pulsed electromagnetic field (PEMF) reportedly promotes the proliferation and neuronal differentiation of BMSCs. Low frequency PEMF can induce the neuronal differentiation of BMSCs in the absence of nerve growth factors. This study was designed to investigate the effects of low frequency PEMF pretreatment on the proliferation and function of BMSCs and the effects of low-frequency PEMF pre-treated BMSCs on the regeneration of injured peripheral nerve using in vitro and in vivo experiments. In in vitro experiments, quantitative DNA analysis was performed to determine the proliferation of BMSCs, and reverse transcription-polymerase chain reaction was performed to detect S100 (Schwann cell marker), glial fibrillary acidic protein (astrocyte marker), and brain-derived neurotrophic factor and nerve growth factor (neurotrophic factors) mRNA expression. In the in vivo experiments, rat models of crush-injured mental nerve established using clamp method were randomly injected with low-frequency PEMF pretreated BMSCs, unpretreated BMSCs or PBS at the injury site (1 * 106 cells). DiI-labeled BMSCs injected at the injury site were counted under the fluorescence microscope to determine cell survival. One or two weeks after cell injection, functional recovery of the injured nerve was assessed using the sensory test with von Frey filaments. Two weeks after cell injection, axonal regeneration was evaluated using histomorphometric analysis and retrograde labeling of trigeminal ganglion neurons. In vitro experiment results revealed that low-frequency PEMF pretreated BMSCs proliferated faster and had greater mRNA expression of growth factors than unpretreated BMSCs. In vivo experiment results revealed that compared with injection of unpretreated BMSCs, injection of low frequency PEMF pretreated BMSCs led to higher myelinated axon count and axon density and more DiI-labeled neurons in the trigeminal ganglia, contributing to rapider functional recovery of injured mental nerve. These findings suggest that low-frequency PEMF pretreatment is a promising approach to enhance the efficacy of cell therapy for peripheral nerve injury repair. PMID- 29451220 TI - Critical role of SDF-1/CXCR4 signaling pathway in stem cell homing in the deafened rat cochlea after acoustic trauma. AB - Previous animal studies have shown that stromal cell-derived factor-1 (SDF-1)/CXC chemokine receptor-4 (CXCR4) signaling pathway plays an important role in the targeted migration of bone marrow-derived mesenchymal stem cells (BMSCs) to the injured area. In the present study, we aimed to investigate the potential role of chemotactic SDF-1/CXCR4 signaling pathway in the homing of transplanted BMSCs to the injured cochlea after noise-induced hearing loss (NIHL) in a rat model. White noise exposure (110 dB) paradigm was used for hearing loss induction in male rats for 6 hours in 5 days. Distortion-product otoacoustic emission (DPOAE) responses were recorded before the experiment and post noise exposure. Hoechst 33342 labeled BMSCs and CXCR4 antagonist (AMD3100)-treated BMSCs were injected into the rat cochlea through the round window. SDF-1 protein expression in the cochlear tissue was assayed using western blot assay. The number of labeled BMSCs reaching the endolymph was determined after 24 hours. SDF-1 was significantly increased in the cochlear tissue of rats in the noise exposure group than in the control group. The number of Hoechst 33342-labeled BMSCs reaching the endolymph of the cochlea was significantly smaller in the AMD3100-treated BMSCs group than in the normal BMSCs group. Our present findings suggest that the SDF-1/CXCR4 signaling pathway has a critical role in BMSCs migration to the injured cochlea in a rat model of noise-induced hearing loss.

PMID- 29451224 TI - Hypogonadism in male thalassemia major patients: pathophysiology, diagnosis and treatment. AB - Failure of pubertal growth, delay or absence of sexual development, infertility and sexual dysfunction due to hypogonadism and defective spermatogenesis are frequent and well recognized disturbances among male patients with transfusion dependent (TD) thalassaemia major (beta-thal). These problems are attributed mainly to the damage caused by chronic anaemia and the deposition of excess iron in the pituitary gland and testicles. This is a short review of male pubertal disorders in patients with beta-thal written by pediatric endocrinologists and haematologists with an interest and active involvement, in the diagnosis and management of these complications in this group of patients. A vigilant clinical evaluation of growth and puberty, as well as an appropriate hormonal evaluation in poly-transfused (TD beta-thal) patients is strongly recommended for early detection and treatment of endocrine dysfunction. Of crucial importance also, is the implementation of an efficient chelation regime from early life, to prevent severe iron load and permanent damage to the endocrine glands, particularly those responsible for gonadal function. PMID- 29451225 TI - Quality of life among adolescents aged 14 to 18 years with Beta-Thalassemia Major (TM) in Qatar. AB - BACKGROUND: Thalassemia is a heterogeneous group of inherited disorders of hemoglobin synthesis. It is a common disease in Mediterranean, Southeast Asia, Indian subcontinent, and Middle East countries, including Qatar. PURPOSE: The aim of this study was to assess the quality of life (QOL) among patients aged 14 to 18 years with thalassemia major (TM) in Qatar and correlates their QOL with bio demographic data of the patients compared to healthy controls. MATERIALS AND METHODS: This cross-sectional study measured the QOL in adolescents with thalassemia major who were attending ambulatory units in a tertiary hospital in Qatar. Forty children and adolescents with TM and 40 healthy participants were enrolled in the study. Forty-two (52.5%) participants were males and 38 (47.5%) females. Data were collected utilizing PedsQLTM 4.0 generic core scale and were analyzed using the appropriate statistical method. RESULTS: Children with TM had significantly lower and more variable overall quality of life score (69.1 +/- 16.8) compared to healthy matched children (77 +/- 12.8), (p <0.001). Both groups were not different from the physical, emotional, and social domains. Thalassemic adolescents had also a significantly lower school performance. CONCLUSIONS: TM adversely affects the QOL of children and adolescents and this necessitates applying more efforts to help them improve and achieve a desirable quality of life. Patients with TM need more attention in schools that can be accomplished by implementing a special program for their management that needs a mutual collaboration between Ministry of Public Health (MoPH) and Ministry of Education (MoE) in Qatar. PMID- 29451226 TI - Final adult height and endocrine complications in young adults with beta thalassemia major (TM) who received oral iron chelation (OIC) in comparison with those who did not use OIC. AB - BACKGROUND: Relatively little is known about endocrine function, bone mineral health, and growth during oral iron chelation therapy in beta-thalassemia major patients (TM) on treatment with deferasirox. AIMS OF THE STUDY: To study the frequency of endocrine complications, IGF-1 levels and final adult standing height (FA-Ht) in patients with BTM in two groups of adult patients. PATIENTS AND METHODS: The first group (Group A; 15 patients, 6 females and 9 males) received oral iron chelation therapy (OIC) with deferasirox for 6 years before puberty; the second group (Group B;40 patients) attained the FA-Ht before the use of OIC (iron chelation therapy with deferoxamine (DFO) given subcutaneously, since the age of 2 years). In both groups liver iron concentration was measured using FerriScan (r) R2-MRI method. Furthermore, the FA-Ht, bode mass index (BMI), and insulin growth factor-1 (IGF-1) in a selected group of adult patients [9 with normal growth hormone (GH) secretion (GHN) and 8 with GH deficiency (GHD; peak GH response to provocative test with clonidine: < 7 ng/ml), who were on iron chelation therapy with DFO given subcutaneously that was changed to oral deferasirox during the last 5-6 years. These 15 patients were not treated with rhGH. RESULTS: Adults with BTM who received OIC for 6 years or more before attaining their FA-Ht, had lower liver iron concentration (LIC) assessed by FerriScan(r) R2-MRI, fasting glucose level (FBG) and liver enzymes (ALT and AST), and a better FA-Ht expressed in standard deviation score (FA-Ht-SDS), and higher IGF-1 SDS versus those who did not receive OIC before attaining FA-Ht. The prevalence of endocrinopathies, including hypothyroidism and hypogonadism were significantly lower in Group A versus Group B. Comparison between the group with normal GHN and those with GHD showed that the FA-Ht-SDS of those with GHD (159.1+/- 6.42 cm). Ht-SDS = -2.5 +/- 0.9) was significantly decreased compared to the group with NGH (Ht = 163.5 +/- 5.2 cm, Ht-SDS = -1.74 +/- 0.83). The IGF 1-SDS did not differ between the two groups. Neither ferritin level nor IGF-1 concentrations were correlated with the Ht-SDS. The final FA-Ht-SDS correlated significantly with the peak GH secretion (r = 0.788, p = 0.0008). The FA-Ht-SDS were positively related to their mid-parental height (r=0.58, P <0.01). CONCLUSIONS: The use of OIC years before the end of puberty was associated with a significantly lower prevalence of endocrinopathies, improvement of LIC and FA-Ht. The final adult height of patients with BTM and GHD was significantly shorter compared to their pears with NGH. rhGH therapy can be recommended for the treatment of thalassemic children and adolescents with GHD in addition to proper blood transfusion and intensive chelation to improve their final height. PMID- 29451227 TI - Statural Growth and Prevalence of Endocrinopathies in Relation to Liver Iron Content (LIC) in Adult Patients with Beta Thalassemia Major (BTM) and Sickle Cell Disease (SCD). AB - Despite regular blood transfusion and iron chelation therapy, growth impairment and pubertal delay are commonly seen in children and adolescents with transfusion dependent Beta thalassaemia major (BTM) and sickle cell disease (SCD). We evaluated growth parameters and endocrine disorders in relation to the liver iron concentration (LIC) assessed by the Ferriscan(r) method in a cohort of adults with SCD (n =40) and BTM (n = 52) receiving blood transfusions and iron chelation therapy since early childhood. Before transfusion, hemoglobin concentration had not been less than 9 g/dl in the past 12 years; subcutaneous daily desferrioxamine was administered for all of them since early childhood (2- 5 years of age). All patients were shifted to oral therapy with deferasirox iron chelation, 20 mg/daily for the past 5 years. BTM patients with higher LIC (> 15 mg Fe/g dry weight) had significantly shorter stature, lower insulin-like growth factor-I SDS (IGF-I SDS), higher alanine transferase (ALT) and serum ferritin concentrations compared to thalassemic patients with lower LIC. Patients with SCD with LIC > 8 mg Fe/g dry weight had significantly shorter stature, lower IGF I SDS and higher ALT compared to SCD patients with lower LIC. Patients with BTM had significantly shorted final height (Ht-SDS) , IGF-I SDS and FT4 level compared to patients with SCD. LIC and mean fasting blood glucose (FBG) were significantly higher in patients with BTM compared to those with SCD. The linear regression analysis showed a significant correlation between LIC and serum ferritin level in SCD and BTM. LIC and serum ferritin level were also correlated significantly with IGF-I level in patients with BTM. LIC was correlated significantly with ALT in patients with BTM. In conclusion, the prevalence of endocrinopathies especially hypothyroidism, DM, and hypogonadism were significantly higher in BTM patients versus SCD patients and higher in patients with higher LIC versus those with lower LIC. These complications occurred less frequently, but still considerable, in chronically transfused patients with SCD. PMID- 29451228 TI - A persistent cough as atypical clinical presentation of intrathoracic extramedullary hematopoiesis (EMH) in a female with thalassemia intermedia. AB - Extramedullary hematopoiesis (EMH) is a rare disorder, defined as the appearance of hematopoietic elements outside the bone marrow or peripheral blood. The most common sites of EMH are liver and spleen, but it has been documented in other organs such as the mediastinum, lymph nodes, breast, and central nervous system. EMH occurs as a compensatory mechanism for bone marrow dysfunction in severe thalassemia. We report a case of EMH presenting as a posterior mediastinal mass in a 34-year-old woman with thalassemia intermedia with chronic cough and shortness of breath on exertion. The diagnosis of EMH was confirmed by a CT guided fine needle biopsy. All symptoms disappeared after surgical removal of the mass. PMID- 29451231 TI - Electron microscopy at the limits.

AB - The Kap Washington Group of post-Palaeozoic explosive volcanic rocks was discovered in 1969 on the north coast of Greenland. Although there have been uncertainties regarding their age and chemical character, they have featured prominently in geotectonic reconstructions of the Arctic regions-in recent interpretations as products of the Yermak hot spot, generated on the Nansen spreading axis during the opening of the Eurasia Basin. We present here new evidence which confirms the volcanicity as end-Cretaceous in age and of peralkaline type. We show that a direct connection with the Yermak hot spot is improbable and infer that the volcanic rocks were generated in a continental extensional rift environment before the break-up of the Laurasian plate in the Arctic. Their age helps to constrain the timing of this poorly understood event. PMID- 29451229 TI - m-AAA proteases, mitochondrial calcium homeostasis and neurodegeneration. AB - The function of mitochondria depends on ubiquitously expressed and evolutionary conserved m-AAA proteases in the inner membrane. These ATP-dependent peptidases form hexameric complexes built up of homologous subunits. AFG3L2 subunits assemble either into homo-oligomeric isoenzymes or with SPG7 (paraplegin) subunits into hetero-oligomeric proteolytic complexes. Mutations in AFG3L2 are associated with dominant spinocerebellar ataxia (SCA28) characterized by the loss of Purkinje cells, whereas mutations in SPG7 cause a recessive form of hereditary spastic paraplegia (HSP7) with motor neurons of the cortico-spinal tract being predominantly affected. Pleiotropic functions have been assigned to m-AAA proteases, which act as quality control and regulatory enzymes in mitochondria. Loss of m-AAA proteases affects mitochondrial protein synthesis and respiration and leads to mitochondrial fragmentation and deficiencies in the axonal transport of mitochondria. Moreover m-AAA proteases regulate the assembly of the mitochondrial calcium uniporter (MCU) complex. Impaired degradation of the MCU subunit EMRE in AFG3L2-deficient mitochondria results in the formation of deregulated MCU complexes, increased mitochondrial calcium uptake and increased vulnerability of neurons for calcium-induced cell death. A reduction of calcium influx into the cytosol of Purkinje cells rescues ataxia in an AFG3L2-deficient mouse model. In this review, we discuss the relationship between the m-AAA protease and mitochondrial calcium homeostasis and its relevance for neurodegeneration and describe a novel mouse model lacking MCU specifically in Purkinje cells. Our results pledge for a novel view on m-AAA proteases that integrates their pleiotropic functions in mitochondria to explain the pathogenesis of associated neurodegenerative disorders. PMID- 29451233 TI - Migration of late Cenozoic volcanism in the South Island of New Zealand and the Campbell Plateau. AB - In late Cenozoic volcanics of eastern Australia, Wellman and McDougall1 have shown a remarkable southward migration pattern of major shield volcanoes of alkaline olivine basalt association which they relate to movement of the continental crust over a fixed mantle hot-spot. Contemporaneous tholeiite lava field provinces do not show a similar pattern. Following their general selection criteria1, I believe a similar situation emerges for New Zealand examples. In the South Island of New Zealand and the adjacent Campbell Plateau and Chatham Rise are several late Cenozoic volcanic centres that rest on a peneplain in Mesozoic and Palaeozoic granites and metamorphic rocks2,3, which is partly mantled by late Cretaceous to mid-Tertiary shallow marine sediments4,5. These major centres of late Cenozoic alkalic volcanism show an eastward decrease in age from ~28 Myr to ~0.5 Myr, presumably reflecting movement of a linear mantle source with respect to the Pacific Plate.

Observations reported here taken in February 1981 suggest that the low frequency attenuation in the spectrum of Cas A is due to the presence of a cold cloud of ionized carbon.

AB - 40Ar/39Ar age spectra on anorthoclase phenocrysts from three pumice clasts in the KBS Tuff yield nearly ideal flat patterns, providing good evidence that the samples have remained undisturbed since crystallization. The ages are concordant at 1.88+/-0.02 Myr, and confirm that the KBS Tuff, a key marker bed in the Koobi Fora Formation, northern Kenya, is now very well dated. These results resolve the conflict between earlier 40Ar/39Ar and conventional K-Ar dating measurements on the KBS Tuff. PMID- 29451238 TI - UK universities plan to fire staff.

AB - Phanerozoic carbonate rocks commonly contain cycles, a few metres thick, which were deposited during progressive shallowing of their oceanic environment1. Each cycle represents a deepening of water in a nearshore area, followed by the accumulation of sediments up to sea level. The causes of the water deepening which begins each cycle are rarely known. Possibilities include tectonic activity that affected the depositional basin and changes in ocean volume due to the expansion and contraction of ice sheets. I report here that similar cycles occur in the Middle Proterozoic Altyn Formation, part of the Belt Supergroup2. The cycles are probably related to vertical tectonic activity which influenced sedimentation in the Belt basin. The presence of shallowing-upward cycles in the Altyn Formation shows that such cycles are not confined to the Phanerozoic. Other Precambrian sequences should be examined to see if they too contain cycles. Where such cycles are found they may give important information about Precambrian tectonism and glaciation.

AB - Mass spectrometer composition measurements of stratospheric negative ions were first made by Arnold and Henschen1 using a balloon-borne instrument. These initial measurements, which were taken at an altitude of 36.5 km, revealed that the major ion species are NO-3(HNO3)a and HSO-4(H2SO4)b(HNO3)c. The suggestion that the unexpected HSO-4 cores are formed from NO-3 cores by a reaction involving stratospheric sulphuric acid vapour1 was strongly supported by laboratory measurements of the relevant ion-molecule reactions by Viggiano and colleagues2. Meanwhile, major instrumental refinements in balloon-borne ion mass spectrometers, including increased mass range, sensitivity and mass resolution, have resulted in the detection of more massive HSO-4(H2SO4)b ions and in the extension of the height range from a thin layer around 35 km to a region extending from 23 to 39 km (refs 3,4). Here we report in situ negative ion composition measurements of even higher sensitivity which led to the detection of previously unobserved ion species. PMID- 29451243 TI - Wild-type tRNATyrG reads the TMV RNA stop codon, but Q base-modified tRNATyrQ does not. AB - Although protein synthesis usually terminates when a stop codon is reached along the messenger RNA sequence, there are examples, mainly in viruses, of the stop codon being suppressed by a tRNA species. A strong candidate for this phenomenon occurs in tobacco mosaic virus (TMV) in the form of two proteins (110K and 160K, of molecular weights 110,000 and 160,000, respectively)1, sharing an N-terminus sequence, which are translated in vitro from a purified species of viral RNA. We have investigated the identity of the tRNA responsible for production of the 160K protein and show here that it is one of the tyrosine tRNAs. Another tyrosine tRNA, in which the first base of the anticodon is highly modified, does not act as a suppressor, indicating the possible regulatory function of such modifications. PMID- 29451244 TI - Near-edge X-ray absorption spectra for metallic Cu and Mn. AB - The measurement of X-ray absorption fine structure of metals- both in the extended region (EXAFS) as well as in the near edge region (XANES)-has been widely discussed (see refs 1-6 for Cu and refs 7-9 for Mn). The recent availability of intense X-ray fluxes from storage rings has usually been exploited for EXAFS leaving the XANES often with poorer resolution than earlier work performed on conventional sources (for example, compare the near edge structure for copper in ref. 1 with refs 3 or 6). In addition, whilst the theory and analysis of EXAFS is relatively well-established2,10, a theory for the strong scattering regime near to the absorption edge has only recently been developed11. We report here the first high resolution XANES spectra for Cu and Mn which were performed at the SRS storage ring at Daresbury. Although both metals have close packed structures consisting of atoms of similar size their local atomic structure is different in detail. Significant differences are found in their respective XANES reflecting the senstivity of this region of the X-ray absorption fine structure to the local atomic structure. Spectra for the two metals have been analysed using the new multiple scattering formalism. This is a real space calculation and unlike a conventional band structure approach it does not require structural periodicity but works from the local arrangement of atoms.

AB - Kalka is one of about 14 major layered mafic-ultramafic intrusions forming the Giles Complex in central Australia1. The stratigraphical section of the Kalka Intrusion passes from a basal pyroxenite zone (450 + m) through norite and olivine gabbro zones (3,500 m) to an uppermost anorthosite zone (800 + m)2. Further resolution into 21 cyclic units is derived from repeated mineral crystallization sequences and cyclical variation in plagioclase and olivine compositions. A conventional interpretation would have a basaltic magma progressively fractionating as crystallization proceeded from mafic base to leucocratic top, with periodic resetting to less evolved states by fresh incursions of primary magma or by convectional overturn within a sealed magma chamber. However, the reconnaissance isotopic data reported here indicate development of a more complex open system. High initial 87Sr/86Sr ratios in conjunction with normal 143Nd/144Nd ratios demonstrate massive contamination by country rock within the main part of the intrusion3. Furthermore, great variation in Sr initial ratios from 0.7049 to 0.7088 suggests substantial changes in magma composition beyond those induced by fractionation. Similar isotopic heterogeneity in the Newer Gabbros of Scotland4 and the Bushveld Complex5 has been attributed to variable contamination or the emplacement of magma batches of differing composition.

AB - Iron-nickel metallic particles have been reported in meteorites1 and lunar2-5 and terrestrial6,7 rocks. The origin of these metallic particles is not unique as they may be formed by (1) condensation from a primordial solar nebula8; (2) crystallization from a melt; and (3) subsolidus reduction reactions under low oxygen or sulphur fugacity. We report here an electron microscopy study of the solid-state microstructural development in olivine single crystals (Fo92) in which half of the iron has been reduced to the metallic state by a gas-solid interaction in the temperature range 950-1,500 degrees C. The reaction, Fo92 >Fo96+metallic Fe(Ni in solid solution)+pyroxene, begins with a homogeneous transformation involving fine-scale metallic precipitates resembling Guinier Preston zones9. The microstructure develops by the growth of the first-formed precipitates during an Ostwald ripening process9 in which the precipitates located in the dislocation sub-boundaries develop in preference to precipitates in the subgrains. On the other hand, pyroxene is first observed to nucleate heterogeneously at pre-existing dislocations and its coarsening rate is more than an order-of-magnitude faster than that of the metallic phase. Besides the textural similarity of the observed microstructures with that reported for some of the lunar materials2, these results have important implications for the physical models of accretion of terrestrial planets, planetesimals and meteorites10, especially with respect to the distribution of siderophile elements. The rate of reaction observed here places constraints on models for the formation of the Earth's core by segregation of a metallic phase with or without reduction.

AB - Recent investigations of Lower Pleistocene sites at Chesowanja have yielded in situ Oldowan and Oldowan-like stone artefacts, evidence of fire and a fragmentary 'robust' australopithecine cranium. Burnt clay found at one artefact locality dated to >1.42+/-0.07 Myr is the earliest known evidence of fire associated with a hominid occupation site. PMID- 29451267 TI - Structural features in ethanol-water mixtures revealed by picosecond fluorescence anisotropy. AB - When an ensemble of molecules is excited with polarized light an anisotropic orientational distribution with respect to the transition dipole moment is produced. This anisotropy can decay in time due to the rotational motion of the molecules and consequently leads to depolarization of the fluorescence1-6. The rate of this rotational motion has been successfully predicted from hydrodynamic theory. How much the rotational relaxation depends on molecular geometry and how much on specific solvent-solute interactions has been studied by picosecond spectroscopy1-6 and other techniques7-9. In all cases so far reported, the rotational behaviour seems to be accounted for by the Debye-Stokes-Einstein (DSE) equation tauR = f/kT. This relates the rotational relaxation time tauR (inversely related to the rotational diffusion coefficient) to the frictional coefficient, f, which is proportional to the product of the shear viscosity, the molecular volume and a constant dependent on the 'stick' or 'slip' boundary conditions3,10,11. We report here, however, that large deviations from DSE behaviour have been observed in the rotational diffusion of the dye cresyl violet in ethanol-water mixtures. Different rotational relaxation times are observed in solutions of the same viscosity but differing composition. This behaviour can be rationalized using previously proposed models for water-ethanol mixtures. PMID- 29451268 TI - How cells live together. PMID- 29451269 TI - Subduction of the Cocos plate in the Mid America Trench. AB - The Mid America Trench, off the Pacific coast of southern Mexico and central America, is the site of northeastward subduction of the Cocos oceanic plate under the North America and Caribbean plates1 (Fig. 1). In Guatemala, the North America and Caribbean plates are separated by the Polochic-Motagua left-lateral strike slip faults (Fig. 1). The trench itself appears to be divided into two distinct sections at its intersection with the Tehuantepec Ridge. To the south the margin of the trench is wide and consists of a well developed shelf basin2 bounded on the east by a huge volcanic cordillera parallel with the trench axis at a distance of ~200 km. In contrast, to the north, the margin is narrow and devoid of shelf basin; landwards, the trans-Mexican volcanic belt trends oblique to the trench. This volcanic chain would be anomalous if it were related to the subduction of the Cocos plate off southern Mexico. In 1979, as part of the International Phase of Ocean Drilling (IPOD) of the Deep Sea Drilling Project, Legs 66 and 67 respectively explored the northern (off Acapulco, Mexico) and southern (off San Jose, Guatemala) section of the Mid America Trench3-6 (Fig. 1). Since then short topographical surveys of the trench have been carried out by RV Jean Charcot8 using the sea-beam technique7. We report here that both sets of data, together with UTMSI multichannel seismic profiles10,11 can be used to reconstruct the processes of subduction along the Mid America Trench.

PMID- 29451274 TI - Helicase-primase inhibitor amenamevir for herpesvirus infection: Towards practical application for treating herpes zoster. AB - Valacyclovir and famciclovir enabled successful systemic therapy for treating herpes simplex virus (HSV) and varicella zoster virus (VZV) infection by their phosphorylation with viral thymidine kinase. Helicase-primase inhibitors (HPIs) inhibit the progression of the replication fork, an initial step in DNA synthesis to separate the double strand into two single strands. The HPIs amenamevir and pritelivir have a novel mechanism of action, once-daily administration with nonrenal excretory characteristics, and clinical efficacy for genital herpes. Amenamevir exhibits anti-VZV and anti-HSV activity while pritelivir only has anti HSV activity. A clinical trial of amenamevir for herpes zoster has been completed, and amenamevir has been licensed and successfully used in 20,000 patients with herpes zoster so far in Japan. We have characterized the features of the antiviral action of amenamevir and, unlike acyclovir, the drug's antiviral activity is not influenced by the viral replication cycle. Amenamevir is opening a new era of antiherpes therapy. PMID- 29451272 TI - The NDPK/NME superfamily: state of the art. AB - Nucleoside diphosphate kinases (NDPK) are nucleotide metabolism enzymes encoded by NME genes (also called NM23). Given the fact that not all NME-encoded proteins are catalytically active NDPKs and that NM23 generally refers to clinical studies on metastasis, we use here NME/NDPK to denote the proteins. Since their discovery in the 1950's, NMEs/NDPKs have been shown to be involved in multiple physiological and pathological cellular processes, but the molecular mechanisms have not been fully determined. Recent progress in elucidating these underlying mechanisms has been presented by experts in the field at the 10th International Congress on the NDPK/NME/AWD protein family in October 2016 in Dubrovnik, Croatia, and is summarized in review articles or original research in this and an upcoming issue of Laboratory Investigation. Within this editorial, we discuss three major cellular processes that involve members of the multi-functional NME/NDPK family: (i) cancer and metastasis dissemination, (ii) membrane remodeling and nucleotide channeling, and iii) protein histidine phosphorylation. PMID- 29451275 TI - Cenegermin for the treatment of neurotrophic keratitis. AB - The trigeminal nerve provides corneal sensitivity and trophic supply to corneal tissues. The impairment of corneal innervation leads to development of neurotrophic keratitis (NK). NK is a rare, degenerative corneal disease characterized by corneal hypo/anesthesia and development of nonhealing corneal epithelial defects and ulcers. NK is a challenging condition with high medical need due to the lack of approved treatments that can restore corneal integrity. Current treatment of NK aims at stimulating corneal healing and preventing disease progression. Cenegermin is a recombinant human nerve growth factor that was safe and well tolerated in preclinical and clinical studies. Cenegermin eye drops were safe and effective in restoring corneal integrity in two phase II clinical trials in patients with NK. The European Commission granted a full marketing authorization to cenegermin eye drops for the treatment of moderate to severe NK in July 2017. PMID- 29451276 TI - Tisagenlecleucel, an approved anti-CD19 chimeric antigen receptor T-cell therapy for the treatment of leukemia. AB - On August 30, 2017, the U.S. Food and Drug Administration (FDA) approved Novartis' tisagenlecleucel (CTL-019, Kymriah), which is a synthetic bioimmune product of anti-CD19 chimeric antigen receptor (CAR) T cells, for the treatment of relapsed/refractory B-cell acute lymphoblastic leukemia (B-ALL). This was a milestone in tumor immunology on account of the significant antitumor effect of tisagenlecleucel for the treatment of relapsed/refractory B-ALL patients. Conventional standard therapies for B-ALL have high failure rates, thus developing new therapies is crucial for patients with B-ALL. Results from clinical trials indicate that anti-CD19 CAR T-cell therapies could successfully induce high response rates in B-ALL patients. However, related toxicities, such as cytokine release syndrome and CAR T-cell-related encephalopathy syndrome, may be severe or even fatal, and the management of such toxicities is therefore vital. This review will focus on the clinical application of anti-CD19 CAR T-cell therapy in B-ALL treatment, including design features of CAR constructs, therapeutic use of tisagenlecleucel, CAR T-cell therapy clinical trials and related toxicity, and prospects for cancer immunotherapy.

PMID- 29451279 TI - Nitrogen doped nanohoops as promising CO2 capturing devices. AB - The impact of climate change in the face of steady or increasing emissions has made the capture and storage of CO2 a priority issue. Supramolecular chemistry is one of the tools that can be used for this task, due to the possibility of tuning intermolecular interactions for the capture of this gas in a selective and efficient way. In this context, this work presents a novel approach for the capture of CO2 based on n-cycloparaphenylenes ([n]-CPPs) doped with nitrogen atoms. This is the first time that the potential of these structures for the capture of polluting gases has been evaluated. Among all the structures analysed, the one yielding the best results (complexation energy of -32.80 kJ mol-1) contains 4 nitrogen atoms per monomer. The topology of the electron density of the host-guest complex and the nature of its non-covalent interactions have been analyzed in this work in order to explain this high binding energy and identify potential structural modifications to improve it. The capability of this system to be used as a sensing device for CO2 using vibrational spectroscopy is also explored. PMID- 29451280 TI - A remote computing based point-of-care colorimetric detection system with a smartphone under complex ambient light conditions. AB - Smartphone-based colorimetric detection has been one of the most commonly used techniques for point-of-care detection in recent years. However, there are two defects in the current detection system. One is the need of a light-tight box to isolate the impact of ambient light, and the other is the increased calculation with the number of probes. In this paper, a colorimetric detection system was coupled with a new color calibration method for detection under complex ambient light conditions. A 3 * 4 colorimetric probe array was used to display the color changes of different analytes. With the color calibration function and the Support Vector Machine discrimination function based on the RGB data captured at 5000 K preloaded in a remote server, the analysis results could be fed back immediately after sending the RGB data captured under complex ambient light conditions by the smartphone to the remote server. The discrimination results showed that this colorimetric detection system has a relatively high accuracy under complex ambient light conditions. An optimal probe selection algorithm (OPSA) based on the improvement of the traditional stepwise discriminant analysis was also proposed to dramatically reduce the number of probes for the identification of various analytes. The analysis results showed that this algorithm significantly simplifies the probe array and the simplified probe array kept exhibiting a good classification performance. Our research eliminates the dependence of smartphone-based colorimetric detection on light-tight boxes and cuts off the redundant probes, thereby greatly improving the portability of smartphone-based colorimetric detection.

One was inactive on human cancer cells, whereas the other showed high cytotoxicity. Based on live cell imaging, both complexes penetrated the cell, but were not detected in the nuclei. Moreover, the inactive complex was trapped in endocytic vesicles, whereas the active complex accumulated in the perinuclear region and inflected phototoxicity upon continuous irradiation. PMID- 29451282 TI - Catalyst surfaces with tunable hydrophilicity and hydrophobicity: metal-organic frameworks toward controllable catalytic selectivity.

The catalysts exhibit remarkable catalytic selective performance for the hydrogenation of different hydrophobic and hydrophilic reactants. PMID- 29451283 TI - A chemo- and regiocontrolled approach to bipyrazoles and pyridones via the reaction of ethyl 5-acyl-4-pyrone-2-carboxylates with hydrazines. AB - Chemo- and regiocontrolled syntheses of pyrazoles and pyridones are presented on the basis of 4-pyrones. A novel approach towards highly functionalized 3,4' bipyrazoles has been developed by using reactions of ethyl 5-acylcomanoates with hydrazines. The acid-promoted double cyclocondensation allows switching of the structure of the pyrazole rings easily through changing both the nature of hydrazine and the reaction conditions. The transformation of 4-pyrones with phenylhydrazine in EtOH at -20 degrees C leads to hydroxypyridones as monoaddition products which can be used as precursors for the preparation of pyridone and pyrazole derivatives. A novel rearrangement of 2-hydroxypyridone to pyrazolyl-1,3-diketones in DMSO was found. The structure and regiochemistry of bipyrazoles were confirmed by X-ray analysis and 2D NMR experiments. PMID- 29451284 TI - Effect of the coverage level of carboxylic acids as a modifier for barium titanate nanoparticles on the performance of poly(vinylidene fluoride)-based nanocomposites for energy storage applications. AB - Surface modification on nanoparticle fillers with organic groups is important to improve the performance of ceramic/polymer nanocomposites. Due to the small coverage level of carboxylic acids on the nanoparticle surface, studies on the use of carboxylic acids as a surface modifier for ceramic nanoparticles have been rarely reported. However, there is no study that proves that a small amount of modifier on the surface of nanoparticles cannot adequately improve the dispersion as well as the compatibility of nanoparticles with the matrix. Herein, we used three carboxylic acids to treat the surface of BaTiO3 (BT) nanoparticles and adjusted the coverage level of the modifiers on the surface of BT nanoparticles through different ways. The nanocomposite films synthesized from the modified BT nanoparticles dispersed in the poly(vinylidene fluoride) (PVDF) polymer matrix were analyzed by dielectric spectroscopy, breakdown strength, leakage currents, and D-E loop measurements. The results show that the molecule dipole moment and polarizability of the modifier greatly influence the permittivity of the nanocomposites as the surface coverage level of the modifiers increases. Due to many influential factors, changes in the breakdown strength of the nanocomposites show diversity for three modifiers as the modifier content increases. For the nanocomposites applied in energy storage, the optimal content of the modifier on the surface of the nanoparticles needs to be determined by combining various properties of the nanocomposites. PMID- 29451285 TI - Modeling solvent evaporation during thin film formation in phase separating polymer mixtures. AB - Preparation of thin films by dissolving polymers in a common solvent followed by evaporation of the solvent has become a routine processing procedure. However, modeling of thin film formation in an evaporating solvent has been challenging due to a need to simulate processes at multiple length and time scales. In this work, we present a methodology based on the principles of linear non-equilibrium thermodynamics, which allows systematic study of various effects such as the changes in the solvent properties due to phase transformation from liquid to vapor and polymer thermodynamics resulting from such solvent transformations. The methodology allows for the derivation of evaporative flux and boundary conditions near each surface for simulations of systems close to the equilibrium. We apply it to study thin film microstructural evolution in phase segregating polymer blends dissolved in a common volatile solvent and deposited on a planar substrate. Effects of the evaporation rates, interactions of the polymers with the underlying substrate and concentration dependent mobilities on the kinetics of thin film formation are studied. PMID- 29451286 TI - Addressing the temperature transferability of structure based coarse graining models. AB - Systematically derived coarse grained (CG) models for molecular liquids do not inherently guarantee transferability to a state point different from its reference, especially when derived on the basis of structure based CG methods like Inverse Monte Carlo (IMC). Several efforts made in the past years to improve the transferability of these models focused on including thermodynamic constraints or on the application of multistate parametrization. Das and Andersen (DA) [Das et al., J. Chem. Phys., 2010, 132, 164106.] proposed a different Ansatz. They derived a correction term added to the system's Hamiltonian to reproduce the virial pressure and the volume fluctuations of the reference system in the CG resolution which does not require further adjustment of the effective pair potential. Herein, we discuss the possibility to achieve temperature transferability with IMC models for selected alkanes following the optimization of the DA approach as proposed by Dunn and Noid (DN) [Dunn et al., J. Chem. Phys., 2015, 143, 243148.]. The work focuses on a novel approach to determine the DN correction term for different state points by linear interpolation. PMID- 29451288 TI - Fibers on the surface of thermo-responsive gels induce 3D shape changes. AB - Using computational modeling, we pattern the outer layers of thin, thermo responsive gels with elastic fibers and thereby design stable structures that could not be achieved with the fibers in the interior of the network. To perform these studies, we simulate the fiber-decorated gels with the gel lattice spring model (gLSM) and determine how the temperature, arrangement and number of the fibers control the bending and curvature of the thin films. We establish arrangements of the fiber on square- and rectangular-shaped gels that yield reversible, pronounced contraction and extension of the layer with changes in temperature. Hence, these composites provide useful actuation. Finally, we cut the gel into a cross-shaped sample to show that the modes of actuation and functionality of the material can be significantly expanded by tailoring not only the fiber placement, but also the initial geometry of the gel. PMID- 29451287 TI - Computational identification of the binding mechanism of a triple reuptake inhibitor amitifadine for the treatment of major depressive disorder. AB - Amitifadine, the only drug ever clinically tested in Phase 3 for treating depression, is a triple reuptake inhibitor (TRI) that simultaneously interacts with human monoamine transporters (MATs) including hSERT, hNET and hDAT. This novel multi-target strategy improves drug efficacy and reduces the toxic side effects of drugs. However, the binding modes accounting for amitifadine's polypharmacological mode of action are still elusive, and extensive exploration of the amitifadine-target interactions between amitifadine and MATs is urgently needed. In this study, a total of 0.63 MUs molecular dynamics (MD) simulations with an explicit solvent as well as endpoint binding free energy (BFE) calculation were carried out. MD simulation results identified a shared binding mode involving eleven key residues at the S1 site of MATs for the binding of amitifadine, and the results of the BFE calculations were in good agreement with experimental reports. Moreover, by analyzing the per-residue energy contribution variation at the S1 site of three MATs and additional cross-mutagenesis simulations, the variation in the inhibition ratio of amitifadine between hSERT and two other MATs was discovered to mainly come from non-conserved residues (Y95, I172 and T439 in hNET and Y95, I172, A169 and T439 in hDAT). As the rational inhibition ratio of multi-target drugs among various therapeutic targets was found to be the key to their safety and tolerance, the findings of this study may further facilitate the rational design of more potent but less toxic multi target antidepressant drugs. PMID- 29451289 TI - Multi-molecular emission of a cationic Pt(ii) complex through hydrogen bonding interactions. AB - The cationic Pt complexes with amide groups have been found to show dimer emission through hydrogen bonding interactions with counter anions even at low concentration. In order to investigate further details of dimer emission, we prepared three Pt complexes, Pt.B(C6F5)4, Pt.Cl, and Pt.PF6, whose counter anions possess different strengths of a hydrogen bonding acceptor. Hydrogen bonding interactions in the ground state and excited-state dynamics of the Pt complexes were evaluated by NMR analysis, temperature dependence, and kinetics of dimer emission. These studies revealed that the hydrogen bonding interaction in the ground state is essential for dimer emission, but too strong hydrogen bonding prevents dimer emission due to the inhibition of a stacked dimer formation in the excited state. Owing to this trade-off, the Pt complex with a moderate hydrogen bonding acceptor, PF6-, most effectively shows dimer emission. In general, a strong supramolecular interaction efficiently provides a desired assembled structure showing multi-molecular emission. We revealed a unique phenomenon that a moderate interaction is beneficial to effective multi-molecular emission. PMID- 29451290 TI - High temperature pyrolysis of 2-methyl furan. AB - The dissociation of 2-methyl furan at high temperatures has been studied in a combined experimental and theoretical approach to elucidate the details of this multi-channel unimolecular reaction. Laser schlieren densitometry studies were performed in a diaphragmless shock tube over the range 1600 < T < 2300 K and three pressures 60, 120 and 240 Torr. The theoretical study identified many reaction paths, most of which are initiated by the formation of carbenes. Of these paths, five account for 99% consumption of 2MF, and three account for 95% consumption. Simulations of the experimental results with a model that incorporated the theoretical predictions of reaction paths failed to reproduce the experimental data. This was resolved by increasing the rate of loss of an H atom from the methyl group in 2-methyl furan by a factor of 2-4. The resulting model provides good simulations of the complete set of experimental data. The branching fractions for the three key reactions are both temperature and pressure dependent. PMID- 29451291 TI - Enhanced glucose sensing based on a novel composite CoII-MOF/Acb modified electrode. AB - In this work, we demonstrate the synthesis and application of a novel CoII-based metal-organic framework {[Co2(Dcpp)(Bpe)0.5 (H2O)(MU2-H2O)].(Bpe)0.5}n (CoII-MOF, H4Dcpp = 4,5-bis(4'-carboxylphenyl)-phthalic acid, Bpe = 1,2-bis(4 pyridyl)ethane) as an electrochemical sensor for glucose detection. Single crystal X-ray diffraction analysis shows that the CoII-MOF has a two-dimensional (2D) bilayer structure composed of Co2 units and Dcpp4- ligands. There are two kinds of Bpe in the structure: one serves as a bidentate ligand linking two Co1 atoms in each 2D layer; the other is just free in the lattice. The CoII-MOF modified glassy carbon electrode (GCE) shows good electrocatalytic activity towards glucose oxidation. To further improve the catalytic activity of the electrode, a new composite of CoII-MOF/acetylene black (CoII-MOF/Acb) was constructed. The CoII-MOF/Acb modified electrode exhibits enhanced sensing behavior for glucose detection. The sensing performance of CoII-MOF/Acb/GCE with different Acb loadings was investigated in detail. The results demonstrate that CoII-MOF/GCE with 2% Acb (CoII-MOF/Acb-2%/GCE) exhibits the best sensing behavior, including a high sensitivity of 0.255 MUA MUM-1 cm-2 and a wide linear range of 5-1000 MUM, as well as a low detection limit of 1.7 MUM (S/N = 3). It's worth noting that the linear range of CoII-MOF/Acb-2%/GCE was extended by more than ten times when compared to that of CoII-MOF/GCE without Acb addition. In addition, CoII-MOF/Acb-2%/GCE shows good selectivity and stability in the sensing process. PMID- 29451292 TI - Multifunctional luminescent magnetic cryocooler in a Gd5Mn2 pyramidal complex. AB - Magnetic cooling is a highly efficient refrigeration technique with the potential of replacing expensive and rare helium-3 in the field of ultra-low temperature cooling. However, the visualization of a cryogen at an extremely low temperature and in a strong magnetic field is challenging, but it is crucial for the precise positioning and in situ thermal probe measurements in potential practical applications. Here, the activation of a red-emissive Mn(ii) ion using 3d/4f chemistry produces a luminescent molecule cooler, [Gd5Mn2(LOMe)2(OH)4(Ac)6(MeOH)10Cl2]Cl3.2MeOH (1), with the core of an Mn(ii) anchored heptanuclear [GdIII5MnII2] pyramid. The photoluminescence (PL) of the Mn2+ emission, with a large Stokes shift (lambdaem ~ 690 nm) from 4T1(4G) -> 6A1(6S), shows not only a sensitive temperature sensing property but also reversible mechanoluminescence (ML). More attractively, these findings reveal a considerable magnetocaloric effect (MCE) coupled with a tunable emission window, opening up new opportunities in the multifunctional applications of PL, ML, and the MCE involving red-light sources, thermometers, and stress imaging. In particular, this provides a novel resolution to design visualized PL coolers. PMID- 29451293 TI - The role of near-wall drag effects in the dynamics of tethered DNA under shear flow. AB - We utilized single-molecule tethered particle motion (TPM) tracking, optimized for studying the behavior of short (0.922 MUm) dsDNA molecules under shear flow conditions, in the proximity of a wall (surface). These experiments track the individual trajectories through a gold nanobead (40 nm in radius), attached to the loose end of the DNA molecules. Under such circumstances, local interactions with the wall become more pronounced, manifested through hydrodynamic interactions. To elucidate the mechanical mechanism that affects the statistics of the molecular trajectories of the tethered molecules, we estimate the resting diffusion coefficient of our system. Using this value and our measured data, we calculate the orthogonal distance of the extended DNA molecules from the surface. This calculation considers the hydrodynamic drag effect that emerges from the proximity of the molecule to the surface, using the Faxen correction factors. Our finding enables the construction of a scenario according to which the tension along the chain builds up with the applied shear force, driving the loose end of the DNA molecule away from the wall. With the extension from the wall, the characteristic times of the system decrease by three orders of magnitude, while the drag coefficients decay to a plateau value that indicates that the molecule still experiences hydrodynamic effects due to its proximity to the wall. PMID- 29451294 TI - Quantification of isomerically summed hydrocarbon contributions to crude oil by carbon number, double bond equivalent, and aromaticity using gas chromatography with tunable vacuum ultraviolet ionization. AB - The ability to structurally characterize and isomerically quantify crude oil hydrocarbons relevant to refined fuels such as motor oil, diesel, and gasoline represents an extreme challenge for chromatographic and mass spectrometric techniques. This work incorporates two-dimensional gas chromatography coupled to a tunable vacuum ultraviolet soft photoionization source, the Chemical Dynamics Beamline 9.0.2 of the Advanced Light Source at the Lawrence Berkeley National Laboratory, with a time-of-flight mass spectrometer (GC * GC-VUV-TOF) to directly characterize and isomerically sum the contributions of aromatic and aliphatic species to hydrocarbon classes of four crude oils. When the VUV beam is tuned to 10.5 +/- 0.2 eV, both aromatic and aliphatic crude oil hydrocarbons are ionized to reveal the complete chemical abundance of C9-C30 hydrocarbons. When the VUV beam is tuned to 9.0 +/- 0.2 eV only aromatic hydrocarbons are ionized, allowing separation of the aliphatic and aromatic fractions of the crude oil hydrocarbon chemical classes in an efficient manner while maintaining isomeric quantification. This technique provides an effective tool to determine the isomerically summed aromatic and aliphatic hydrocarbon compositions of crude oil, providing information that goes beyond typical GC * GC separations of the most dominant hydrocarbon isomers. PMID- 29451295 TI - Evaluation of HIF-1alpha and iNOS in ischemia/reperfusion gastric model: bioimpedance, histological and immunohistochemical analyses. AB - : Gastrointestinal ischemia/reperfusion (I/R) generates pathological alterations that could lead to death. Early ischemic damage markers could be used to guide therapy and improve outcomes. AIM: To relate hypoxia-inducible factor 1alpha (HIF 1alpha) activation and inducible nitric oxide synthase (iNOS) expression to gastric impedance changes due to I/R damage. METHODS: Experimental animals were randomly distributed into 3 groups: control, ischemia (30 min) and I/R (60 min). Gastric ischemia was generated by celiac artery clamping for 30 min, and then blood flow was restored for 60 min. Impedance spectra and biopsies of the glandular portion were obtained for histological and immunohistochemical analyses. Immunodetection of both HIF-1alpha and iNOS was performed. RESULTS: Under ischemia and I/R conditions, there was an increase (p<0.05) in the impedance parameters. Histologically, under ischemic conditions, edema and necrosis were observed in epithelium and significant vascular congestion. In I/R condition, alterations of the glandular and luminal integrity were found, which generated areas of epithelial erosion. Immunohistochemical analysis of HIF-1alpha revealed an increase (p<0.01) in the number of immunoreactive cells in the ischemia (35.7+/-13.9) and I/R (119.9+/-18.8) conditions compared to the control (0.8+/-1.2). Immunodetection of iNOS showed an increase (p<0.01) in the number of cells expressing iNOS under the ischemia (5.4+/-2.9) and I/R conditions (27.4+/ 11.3) was observed compared to the control (0.4+/-0.8). CONCLUSION: Early changes in impedance in response to I/R is related to histopathological changes, the nuclear stabilization and translocation of HIF-1alpha as well as expression of iNOS. PMID- 29451296 TI - Investigation of the urinary metabolic variations and the application in bladder cancer biomarker discovery. AB - Urine metabolomics have been used to identify biomarkers for clinical diseases. However, inter-individual variations and effect factors need to be further evaluated. In our study, we explored the urine metabolome in a cohort of 203 health adults, 6 patients with benign bladder lesions, and 53 patients with bladder cancer (BCa) using liquid chromatography coupled with high resolution mass spectrometry. Inter-individual analysis of both healthy controls and BCa patients showed that the urine metabolome was relatively stable. Further analysis indicated that sex and age affect inter-individual variations in urine metabolome. Metabolic pathways such as tryptophan metabolism, the citrate cycle, and pantothenate and CoA biosynthesis were found to be related to sex and age. To eliminate age and sex interference, additional BCa urine metabolomic biomarkers were explored using age and sex-matched urine samples (Test group: 44 health adults vs. 33 patients with BCa). Metabolic profiling of urine could significantly differentiate the cases with cancer from the controls and high grade from low-grade BCa. A metabolite panel consisting of trans-2 dodecenoylcarnitine, serinyl-valine, feruloyl-2-hydroxyputrescine, and 3 hydroxynonanoyl carnitine were discovered to have good predictive ability for BCa with an area under the curve (AUC) of 0.956 (cross validation: AUC = 0.924). A panel of indolylacryloylglycine, N2 -galacturonyl-L-lysine, and aspartyl glutamate was used to establish a robust model for high- and low-grade BCa distinction with AUC of 0.937 (cross validation: AUC = 0.891). External sample (26 control vs. 20 BCa) validation verified the acceptable accuracy of these models for BCa detection. Our study showed that urinary metabolomics is a useful strategy for differential analysis and biomarker discovery. PMID- 29451297 TI - Enhancement of the conductivity detection signal in capillary electrophoresis systems using neutral cyclodextrins as sweeping agents. AB - Conductivity detection is a universal detection technique often encountered in electrophoretic separation systems, especially in modern chip-electrophoresis based devices. On the other hand, it is sparsely combined with another contemporary trend of enhancing limits of detection by means of various preconcentration strategies. This can be attributed to the fact that a preconcentration experimental setup usually brings about disturbances in a conductivity baseline. Sweeping with a neutral sweeping agent seems a good candidate for overcoming this problem. A neutral sweeping agent does not hinder the conductivity detection while a charged analyte may preconcentrate on its boundary due to a decrease in its effective mobility. This study investigates such sweeping systems theoretically, by means of computer simulations, and experimentally. A formula is provided for the reliable estimation of the preconcentration factor. Additionally, it is demonstrated that the conductivity signal can significantly benefit from slowing down the analyte and thus the overall signal enhancement can easily overweight amplification caused solely by the sweeping process. The overall enhancement factor can be deduced a priori from the linearized theory of electrophoresis implemented in the PeakMaster freeware. Sweeping by neutral cyclodextrin is demonstrated on an amplification of a conductivity signal of flurbiprofen in a real drug sample. Finally, a possible formation of unexpected system peaks in systems with a neutral sweeping agent is revealed by the computer simulation and confirmed experimentally. PMID- 29451298 TI - Micro-computed tomography visualization of the vestigial alimentary canal in adult oestrid flies. AB - Oestrid flies (Diptera: Oestridae) do not feed during the adult stage as they acquire all necessary nutrients during the parasitic larval stage. The adult mouthparts and digestive tract are therefore frequently vestigial; however, morphological data on the alimentary canal in adult oestrid flies are scarce and a proper visualization of this organ system within the adult body is lacking. The present work visualizes the morphology of the alimentary canal in adults of two oestrid species, Oestrus ovis L. and Hypoderma lineatum (de Villiers), with the use of non-invasive micro-computed tomography (micro-CT) and compares it with the highly developed alimentary canal of the blow fly Calliphora vicina Robineau Desvoidy (Diptera: Calliphoridae). Both O. ovis and H. lineatum adults showed significant reductions of the cardia and the diameter of the digestive tract, an absence of the helicoidal portion of the midgut typical of other cyclorrhaphous flies, and a lack of crop and salivary glands. Given the current interest in the alimentary canal in adult dipterans in biomedical and developmental biology studies, further understanding of the morphology and development of this organ system in adult oestrids may provide valuable new insights in several areas of research. PMID- 29451299 TI - Low childhood subjective social status and telomere length in adulthood: The role of attachment orientations. AB - Low subjective social status (SSS) in childhood places one at greater risk of a number of health problems in adulthood. Theoretical and empirical evidence indicates that exposure to supportive parenting may buffer the negative effects of low childhood SSS on adult health. Given the importance of supportive caregivers and close others for the development of attachment orientations throughout the lifespan, attachment theory may be important for understanding why some individuals are resilient to the negative effects of low childhood SSS on adult health while others are not. We examined if attachment anxiety and attachment avoidance altered the association between childhood subjective social status (SSS) and length of telomeres in white blood cells in adulthood. Shorter telomere length is associated with increased risk of age-related diseases including cancer, type 2 diabetes, and cardiovascular disease. Participants (N = 128) completed self-report measures of childhood SSS and attachment orientations, as well as a blood draw. We found that among those with low childhood SSS, low attachment anxiety was associated with longer telomere length in white blood cells in comparison to high attachment anxiety controlling for participant age, sex, race, body mass index, and adult SSS. Among those with high childhood SSS, low attachment anxiety was associated with a slight decrease in telomere length. Attachment avoidance was unrelated to length of telomeres. Such findings provide further evidence for the role that close relationships may have on buffering SSS related health disparities. PMID- 29451300 TI - Decreased anterior cingulate activation in a motor task in youths with bipolar disorder. AB - BACKGROUND: Bipolar disorder (BP) is characterized by abnormal shifts in mood between episodes of mania and severe depression, both of which have been linked with psychomotor disturbances. This study compares brain activation patterns in motor networks between euthymic youths with BP and healthy controls (HC) during the completion of a simple motor task. METHODS: Thirty-five youths with BP and 35 HC (aged 10-19) completed a self-paced sequential bilateral finger-tapping task, consisting of a 4-minute scan block with alternating 20-second periods of either the tapping task (six blocks) or rest (six blocks), while undergoing functional magnetic resonance imaging. Clinical and behavioral symptoms were assessed using the Child Behavior Checklist (CBCL). A between-group whole-brain analysis compared activation pattern differences while controlling for effects of age and sex. Clusters meeting whole-brain false discovery rate (FDR) correction (qFDR < .05) were considered statistically significant. Post hoc analyses evaluating comorbid attention-deficit/hyperactivity disorder (ADHD) in the BP group were also conducted. RESULTS: Significantly decreased activation was found in the anterior cingulate cortex (ACC) in youths with BP compared to HC. Furthermore, ACC activation was negatively correlated with CBCL mood dysregulation profile scores in the BP group. No significant differences in functional activation patterns were found between youths with BP and comorbid ADHD and those with only BP. CONCLUSIONS: These findings suggest a potential common mechanism of impaired ACC modulation between emotion dysregulation and motor processing in youths with BP. PMID- 29451302 TI - Comparing cytotoxic backbones for first-line trastuzumab-containing regimens in human epidermal growth factor receptor 2-positive advanced oesophagogastric cancer: A meta-analysis. AB - According to the Trastuzumab for Gastric Cancer (ToGA) study, trastuzumab plus cisplatin and capecitabine/5-fluorouracil (5-FU) is standard first-line treatment for human epidermal growth factor receptor 2 (HER2)-positive advanced oesophagogastric cancer. We examined the relative efficacy and safety of alternative trastuzumab-based cytotoxic backbone regimens compared to the standard ToGA regimen using meta-analysis. We searched Medline, EMBASE, CENTRAL and ASCO and ESMO up to March 2017 for studies investigating alternative first line trastuzumab-based regimens for HER2-positive oesophagogastric cancer, defined as high protein expression IHC3+ or IHC2+ and gene amplification by in situ hybridisation. We compared primary outcome overall survival (OS) of alternative trastuzumab-based regimens to the ToGA regimen. Hazard ratios (HRs) and 95% confidence intervals (95%CI) were calculated by extraction of the published Kaplan-Meier curves. Incidence counts and toxicity sample-sizes were extracted for adverse events and compared using single-arm proportion meta analysis in R. Fifteen studies (N = 557 patients) were included. OS was significantly longer with regimen trastuzumab plus doublet oxaliplatin and capecitabine/5-FU (median OS = 20.7 months) versus ToGA (16.0 months, HR = 0.75, 95% CI = 0.59-0.99) and was less toxic. Trastuzumab plus doublet cisplatin and S 1 showed no OS difference versus ToGA, but showed a different toxicity profile, including less hand-foot syndrome. Trastuzumab plus cisplatin or capecitabine as singlet backbone showed significantly worse survival and more toxicity versus ToGA regimen. Trastuzumab with triplet cytotoxic backbones or with bevacizumab and doublet cytotoxic backbone showed no survival benefit and more toxicity. In conclusion, trastuzumab plus doublet cytotoxic backbone containing oxaliplatin is preferable over the ToGA regimen with cisplatin. S-1 can substitute capecitabine or 5-FU when specific toxicities are encountered. PMID- 29451301 TI - INTU-related oral-facial-digital syndrome type VI: A confirmatory report. AB - Oral-facial-digital (OFD) syndromes are a subgroup of ciliopathies distinguished by the co-occurrence of hamartomas and/or multiple frenula of the oral region and digital anomalies. Several clinical forms of OFD syndromes are distinguished by their associated anomalies and/or inheritance patterns, and at least 20 genetic types of OFD syndromes have been delineated. We describe here a child with preaxial and postaxial polydactyly, lingual hamartoma, a congenital heart defect, delayed development and cerebellar peduncles displaying the molar tooth sign. Whole-exome sequencing and SNP array identified compound heterozygous variants in the INTU gene, which encodes a protein involved in the positioning of the ciliary basal body. INTU is a subunit of the CPLANE multiprotein complex essential for the assembly of IFT-A particles and intraflagellar transport. This report of a second patient with INTU-related OFD syndrome and the further delineation of its neuroimaging and skeletal phenotype now allow INTU-related OFD syndromes to be classified within the OFD syndrome type VI group. Patients display a phenotype similar to that of mice with a hypomorphic mutation of Intu, but with the addition of a heart defect. PMID- 29451303 TI - Sex-specific manifestation of genetic risk for attention deficit hyperactivity disorder in the general population. AB - BACKGROUND: Attention deficit hyperactivity disorder (ADHD) is more commonly diagnosed in males than in females. A growing body of research suggests that females with ADHD might be underdiagnosed or receive alternative diagnoses, such as anxiety or depression. Other lines of reasoning suggest that females might be protected from developing ADHD, requiring a higher burden of genetic risk to manifest the disorder. METHODS: We tested these two hypotheses, using common variant genetic data from two population-based cohorts. First, we tested whether females and males diagnosed with anxiety or depression differ in terms of their genetic risk for ADHD, assessed as polygenic risk scores (PRS). Second, we tested whether females and males with ADHD differed in ADHD genetic risk burden. We used three different diagnostic definitions: registry-based clinical diagnoses, screening-based research diagnoses and algorithm-based research diagnoses, to investigate possible referral biases. RESULTS: In individuals with a registry based clinical diagnosis of anxiety or depression, females had higher ADHD PRS than males [OR(CI) = 1.39 (1.12-1.73)] but there was no sex difference for screening-based [OR(CI) = 1.15 (0.94-1.42)] or algorithm-based [OR(CI) = 1.04 (0.89-1.21)] diagnoses. There was also no sex difference in ADHD PRS in individuals with ADHD diagnoses that were registry-based [OR(CI) = 1.04 (0.84 1.30)], screening-based [OR(CI) = 0.96 (0.85-1.08)] or algorithm-based [OR(CI) = 1.15 (0.78-1.68)]. CONCLUSIONS: This study provides genetic evidence that ADHD risk may be more likely to manifest or be diagnosed as anxiety or depression in females than in males. Contrary to some earlier studies, the results do not support increased ADHD genetic risk in females with ADHD as compared to affected males. PMID- 29451304 TI - Distinct methylation profile of mucinous ovarian carcinoma reveals susceptibility to proteasome inhibitors. AB - Mucinous type of epithelial ovarian cancer (MuOC) is a unique subtype with a poor survival outcome in recurrent and advanced stages. The role of type-specific epigenomics and its clinical significance remains uncertain. We analyzed the methylomic profiles of 6 benign mucinous adenomas, 24 MuOCs, 103 serous type of epithelial ovarian cancers (SeOCs) and 337 nonepithelial ovarian cancers. MuOC and SeOC exhibited distinct DNA methylation profiles comprising 101 genes, 81 of which exhibited low methylation in MuOC and were associated with the response to glucocorticoid, ATP hydrolysis-coupled proton transport, proteolysis involved in the cellular protein catabolic process and ion transmembrane transport. Hierarchical clustering analysis showed that the profiles of MuOC were similar to colorectal adenocarcinoma and stomach adenocarcinoma. Genetic interaction network analysis of differentially methylated genes in MuOC showed a dominant network module is the proteasome subunit beta (PSMB) family. Combined functional module and methylation analysis identified PSMB8 as a candidate marker for MuOC. Immunohistochemical staining of PSMB8 used to validate in 94 samples of ovarian tumors (mucinous adenoma, MuOC or SeOC) and 62 samples of gastrointestinal cancer. PSMB8 was commonly expressed in MuOC and gastrointestinal cancer samples, predominantly as strong cytoplasmic and occasionally weak nuclei staining, but was not expressed in SeOC samples. Carfilzomib, a second-generation proteasome inhibitor, suppressed MuOC cell growth in vitro. This study unveiled a mucinous type-specific methylation profile and suggests the potential use of a proteasome inhibitor to treat MuOC.

PMID- 29451307 TI - Phenological responses to multiple environmental drivers under climate change: insights from a long-term observational study and a manipulative field experiment. AB - Climate change has induced pronounced shifts in the reproductive phenology of plants, yet we know little about which environmental factors contribute to interspecific variation in responses and their effects on fitness. We integrate data from a 43 yr record of first flowering for six species in subalpine Colorado meadows with a 3 yr snow manipulation experiment on the perennial forb Boechera stricta (Brassicaceae) from the same site. We analyze shifts in the onset of flowering in relation to environmental drivers known to influence phenology: the timing of snowmelt, the accumulation of growing degree days, and photoperiod. Variation in responses to climate change depended on the sequence in which species flowered, with early-flowering species reproducing faster, at a lower heat sum, and under increasingly disparate photoperiods relative to later flowering species. Early snow-removal treatments confirm that the timing of snowmelt governs observed trends in flowering phenology of B. stricta and that climate change can reduce the probability of flowering, thereby depressing fitness. Our findings suggest that climate change is decoupling historical combinations of photoperiod and temperature and outpacing phenological changes for our focal species. Accurate predictions of biological responses to climate change require a thorough understanding of the factors driving shifts in phenology. PMID- 29451306 TI - Supraspinal modulation of neuronal synchronization by nociceptive stimulation induces an enduring reorganization of dorsal horn neuronal connectivity. AB - KEY POINTS: The state of central sensitization induced by the intradermic injection of capsaicin leads to structured (non-random) changes in functional connectivity between dorsal horn neuronal populations distributed along the spinal lumbar segments in anaesthetized cats. The capsaicin-induced changes in neuronal connectivity and the concurrent increase in secondary hyperalgesia are transiently reversed by the systemic administration of small doses of lidocaine, a clinically effective procedure to treat neuropathic pain. The effects of both capsaicin and lidocaine are greatly attenuated in spinalized preparations, showing that supraspinal influences play a significant role in the shaping of nociceptive-induced changes in dorsal horn functional neuronal connectivity. We conclude that changes in functional connectivity between segmental populations of dorsal horn neurones induced by capsaicin and lidocaine result from a cooperative adaptive interaction between supraspinal and spinal neuronal networks, a process that may have a relevant role in the pathogenesis of chronic pain and analgesia. ABSTRACT: Despite a profusion of information on the molecular and cellular mechanisms involved in the central sensitization produced by intense nociceptive stimulation, the changes in the patterns of functional connectivity between spinal neurones associated with the development of secondary hyperalgesia and allodynia remain largely unknown. Here we show that the state of central sensitization produced by the intradermal injection of capsaicin is associated with structured transformations in neuronal synchronization that lead to an enduring reorganization of the functional connectivity within a segmentally distributed ensemble of dorsal horn neurones. These changes are transiently reversed by the systemic administration of small doses of lidocaine, a clinically effective procedure to treat neuropathic pain. Lidocaine also reduces the capsaicin-induced facilitation of the spinal responses evoked by weak mechanical stimulation of the skin in the region of secondary but not primary hyperalgesia. The effects of both intradermic capsaicin and systemic lidocaine on the segmental correlation and coherence between ongoing cord dorsum potentials and on the responses evoked by tactile stimulation in the region of secondary hyperalgesia are greatly attenuated in spinalized preparations, showing that supraspinal influences are involved in the reorganization of the nociceptive-induced structured patterns of dorsal horn neuronal connectivity. We conclude that the structured reorganization of the functional connectivity between the dorsal horn neurones induced by capsaicin nociceptive stimulation results from cooperative interactions between supraspinal and spinal networks, a process that may have a relevant role in the shaping of the spinal state in the pathogenesis of chronic pain and analgesia. PMID- 29451308 TI - Apheresis buffy coat collection without photoactivation has no effect on apoptosis, cell proliferation, and total viability of mononuclear cells collected using photopheresis systems. AB - BACKGROUND: Extracorporeal photopheresis (ECP) has been approved for the treatment of advanced cutaneous T-cell lymphoma since 1988. While the precise mechanisms resulting in clinical effects are not fully understood, the photoactivation of mononuclear cells (MNCs) using ultraviolet A (UVA) light and methoxsalen is believed to be the predominant initiating process. The effects of MNC passage through the instrument without photoactivation are unknown. The objective of this study was to evaluate the effect of cell processing through the photopheresis instruments on MNCs. STUDY DESIGN AND METHODS: Fourteen healthy male subjects underwent one simulated ECP procedure without reinfusion of buffy coats (BCs) in a two-center, open-label, prospective trial. Baseline peripheral blood BC, apheresis-separated untreated BC (BC1), and photoactivated BC (BC2) were evaluated in culture for viability by dye exclusion, apoptosis by annexin V binding, and cell proliferation response to phytohemagglutinin (PHA) stimulation by bromodeoxyuridine (BrdU) incorporation. RESULTS: Photoactivation (BC2) resulted in 88% expression of annexin V by Day 1 of culture compared with 37 and 39% for baseline and untreated BC1. Cell viability by propidium iodide exclusion was reduced to 10% in BC2 on Day 1 versus 65 and 60% for baseline and BC1. The proliferative response to PHA stimulation was 97% inhibited in the photoactivated BC2. CONCLUSIONS: These results demonstrate that the mechanical processes used for cell separation and processing of the BC in the absence of photoactivation do not induce a significant amount of apoptosis compared to the standard ECP with methoxsalen and UVA photoactivation. PMID- 29451309 TI - Antibodies to human neutrophil antigen HNA-3b implicated in cases of neonatal alloimmune neutropenia. AB - BACKGROUND: Neonatal alloimmune neutropenia results from maternal alloimmunization to human neutrophil antigens. The alloantibodies involved in neonatal alloimmune neutropenia are against human neutrophil antigens HNA-1a, HNA 1b, HNA-1c, HNA-1d, HNA-2, HNA-3a, HNA-4a, HNA-4b, and HNA-5a; however, to date, antibodies specific to HNA-3b have not been reported. STUDY DESIGN AND METHODS: Blood samples from 10,000 unselected neonates were analyzed, resulting in the selection of 88 neutropenic newborns (neutrophil count <1.5 * 109 /L) from 83 mothers (three pairs of twins and one triplet). HNA-3 genotyping was performed by polymerase chain reaction-restriction fragment length polymorphism to identify the cases of maternal-fetal HNA-3 incompatibility. Serologic studies for detecting maternal HNA-3 alloantibodies were performed with the granulocyte agglutination test, the white blood cell immunofluorescence test, and a LABScreen Multi-HNA Kit. RESULTS: Genotyping studies identified 13 of 88 (14.8%) instances of maternal-fetal HNA-3 incompatibility, with all mothers typed as HNA-3a/a and neonates typed as HNA-3a/b. Serologic studies revealed that five of 13 (38.5%) mothers carried anti-HNA-3b plus human leukocyte antigen antibodies and that three of 13 (23.1%) mothers had anti-HNA-3b without human leukocyte antigen antibodies. CONCLUSION: Here, we report the first three cases of neonatal alloimmune neutropenia associated with HNA-3b antibodies resulting in a neonatal alloimmune neutropenia incidence of one in 3333 live births. PMID- 29451311 TI - Impaired phloem loading in zmsweet13a,b,c sucrose transporter triple knock-out mutants in Zea mays. AB - Crop yield depends on efficient allocation of sucrose from leaves to seeds. In Arabidopsis, phloem loading is mediated by a combination of SWEET sucrose effluxers and subsequent uptake by SUT1/SUC2 sucrose/H+ symporters. ZmSUT1 is essential for carbon allocation in maize, but the relative contribution to apoplasmic phloem loading and retrieval of sucrose leaking from the translocation path is not known. Here we analysed the contribution of SWEETs to phloem loading in maize. We identified three leaf-expressed SWEET sucrose transporters as key components of apoplasmic phloem loading in Zea mays L. ZmSWEET13 paralogues (a, b, c) are among the most highly expressed genes in the leaf vasculature. Genome edited triple knock-out mutants were severely stunted. Photosynthesis of mutants was impaired and leaves accumulated high levels of soluble sugars and starch. RNA seq revealed profound transcriptional deregulation of genes associated with photosynthesis and carbohydrate metabolism. Genome-wide association study (GWAS) analyses may indicate that variability in ZmSWEET13s correlates with agronomical traits, especifically flowering time and leaf angle. This work provides support for cooperation of three ZmSWEET13s with ZmSUT1 in phloem loading in Z. mays.

PMID- 29451312 TI - YODA MAP3K kinase regulates plant immune responses conferring broad-spectrum disease resistance. AB - Mitogen-activated protein kinases (MAPKs) cascades play essential roles in plants by transducing developmental cues and environmental signals into cellular responses. Among the latter are microbe-associated molecular patterns perceived by pattern recognition receptors (PRRs), which trigger immunity. We found that YODA (YDA) - a MAPK kinase kinase regulating several Arabidopsis developmental processes, like stomatal patterning - also modulates immune responses. Resistance to pathogens is compromised in yda alleles, whereas plants expressing the constitutively active YDA (CA-YDA) protein show broad-spectrum resistance to fungi, bacteria, and oomycetes with different colonization modes. YDA functions in the same pathway as ERECTA (ER) Receptor-Like Kinase, regulating both immunity and stomatal patterning. ER-YDA-mediated immune responses act in parallel to canonical disease resistance pathways regulated by phytohormones and PRRs. CA-YDA plants exhibit altered cell-wall integrity and constitutively express defense associated genes, including some encoding putative small secreted peptides and PRRs whose impairment resulted in enhanced susceptibility phenotypes. CA-YDA plants show strong reprogramming of their phosphoproteome, which contains protein targets distinct from described MAPKs substrates. Our results suggest that, in addition to stomata development, the ER-YDA pathway regulates an immune surveillance system conferring broad-spectrum disease resistance that is distinct from the canonical pathways mediated by described PRRs and defense hormones. PMID- 29451314 TI - Aortic Diameters and Mild Functional Aortic Regurgitation in Hypertensive and Normotensive People: Do They Carry the Same Meaning? AB - OBJECTIVES: The association between the aortic root diameter and aortic regurgitation in hypertensive and normotensive people is still disputed, and the underlying mechanisms remain to be clearly elucidated. We aimed to investigate the relationship between the aortic root diameter and trivial to mild functional aortic regurgitation in never-treated hypertensive patients with a new diagnosis compared with healthy normotensive participants. METHODS: A total of 182 hypertensives and 232 age-matched normotensives were included in the study. Anthropometric and office blood pressure (BP) measurements, echocardiography, and a carotid stiffness assessment were performed in all of the participants. Aortic measures for the annulus, sinuses of Valsalva, sinotubular junction, and ascending aorta were taken in late diastole according to the leading-edge method. RESULTS: The mean age of all participants was 52 years. Hypertensive patients had a significantly higher body surface area, mean arterial pressure, and pulse pressure (P < .0001) than normotensive participants. Annulus and sinotubular junction diameters adjusted for confounders and indexed to the body surface area were significantly higher in normotensives than in hypertensives. The prevalence of functional aortic regurgitation was higher in hypertensives (34.8% versus 15.4%; P < .0001). Among the hypertensives, no difference in aortic diameters was found between patients with or without functional aortic regurgitation, whereas normotensives with functional aortic regurgitation had larger aortic root diameters. Aging and BP among the hypertensives were the main determinants of functional aortic regurgitation. CONCLUSIONS: Hypertensive patients had a smaller indexed aortic root diameter than normotensive participants but had a higher prevalence of trivial to mild functional aortic regurgitation. The aging process is the main determinant of functional aortic regurgitation in both groups, but high BP also plays an important role in hypertensives. PMID- 29451313 TI - Drivers and mechanisms of tree mortality in moist tropical forests. AB - Tree mortality rates appear to be increasing in moist tropical forests (MTFs) with significant carbon cycle consequences. Here, we review the state of knowledge regarding MTF tree mortality, create a conceptual framework with testable hypotheses regarding the drivers, mechanisms and interactions that may underlie increasing MTF mortality rates, and identify the next steps for improved understanding and reduced prediction. Increasing mortality rates are associated with rising temperature and vapor pressure deficit, liana abundance, drought, wind events, fire and, possibly, CO2 fertilization-induced increases in stand thinning or acceleration of trees reaching larger, more vulnerable heights. The majority of these mortality drivers may kill trees in part through carbon starvation and hydraulic failure. The relative importance of each driver is unknown. High species diversity may buffer MTFs against large-scale mortality events, but recent and expected trends in mortality drivers give reason for concern regarding increasing mortality within MTFs. Models of tropical tree mortality are advancing the representation of hydraulics, carbon and demography, but require more empirical knowledge regarding the most common drivers and their subsequent mechanisms. We outline critical datasets and model developments required to test hypotheses regarding the underlying causes of increasing MTF mortality rates, and improve prediction of future mortality under climate change. PMID- 29451315 TI - Sensitivity to the Sampling Process Emerges From the Principle of Efficiency. AB - Humans can seamlessly infer other people's preferences, based on what they do. Broadly, two types of accounts have been proposed to explain different aspects of this ability. The first account focuses on spatial information: Agents' efficient navigation in space reveals what they like. The second account focuses on statistical information: Uncommon choices reveal stronger preferences. Together, these two lines of research suggest that we have two distinct capacities for inferring preferences. Here we propose that this is not the case, and that spatial-based and statistical-based preference inferences can be explained by the assumption that agents are efficient alone. We show that people's sensitivity to spatial and statistical information when they infer preferences is best predicted by a computational model of the principle of efficiency, and that this model outperforms dual-system models, even when the latter are fit to participant judgments. Our results suggest that, as adults, a unified understanding of agency under the principle of efficiency underlies our ability to infer preferences.

PMID- 29451317 TI - Ultrasound-Guided Microinvasive Carpal Tunnel Release Using a Novel Retractable Needle-Mounted Blade: A Cadaveric Study. AB - Ultrasound (US)-guided microinvasive procedures are defined as those performed via needles without notable scarring. Ten cadaver hands underwent US-guided microinvasive carpal tunnel release using a novel needle-based tool, the micro i Blade (Summit Medical Products, Inc, Sandy, UT). A US-imaged landmark, the inflexion point of the ligaments distal to the hook of the hamate, was used to position the distal extent of the cut. The transverse carpal ligament was successfully released in all hands without damage to nerves or arteries. In 3 specimens, the fascia between the thenar and hypothenar muscles was partly preserved, whereas the palmar aponeurosis was partly cut in 1 specimen. The micro i-Blade with the cutting knife retracted was also useful as a probe palpated through the palm of the cadaver hand, to test the release of the transverse carpal ligament and to guide the procedure.

PMID- 29451322 TI - Intuitive Probabilities and the Limitation of Moral Imagination. AB - There is a vast literature that seeks to uncover features underlying moral judgment by eliciting reactions to hypothetical scenarios such as trolley problems. These thought experiments assume that participants accept the outcomes stipulated in the scenarios. Across seven studies (N = 968), we demonstrate that intuition overrides stipulated outcomes even when participants are explicitly told that an action will result in a particular outcome. Participants instead substitute their own estimates of the probability of outcomes for stipulated outcomes, and these probability estimates in turn influence moral judgments. Our findings demonstrate that intuitive likelihoods are one critical factor in moral judgment, one that is not suspended even in moral dilemmas that explicitly stipulate outcomes. Features thought to underlie moral reasoning, such as intention, may operate, in part, by affecting the intuitive likelihood of outcomes, and, problematically, moral differences between scenarios may be confounded with non-moral intuitive probabilities. PMID- 29451321 TI - Predicting recovery in acute poststroke aphasia. AB - OBJECTIVE: Many stroke patients show remarkable recovery of language after initial severe impairment, but it is difficult to predict which patients will show good recovery. We aimed to identify patient and lesion characteristics that together predict the best naming outcome in 4 studies. METHODS: We report 2 longitudinal studies that identified 2 variables at onset that were strongly associated with good recovery of naming (the most common residual deficit in aphasia) in the first 6 months after stroke: damage to left posterior superior temporal gyrus (pSTG) and/or superior longitudinal fasciculus/arcuate fasciculus (SLF/AF), and selective serotonin reuptake inhibitor (SSRI) use. We then tested these variables in 2 independent cohorts of chronic left hemisphere stroke patients, using chi-square tests and multivariate logistic regression for dichotomous outcomes and t tests for continuous outcomes. RESULTS: Lesion load in left pSTG and SLF/AF was associated with poorer naming outcome. Preservation of these areas and use of SSRIs were associated with naming recovery, independent of lesion volume, time since stroke, and depression. Patients with damage to these critical areas showed better naming outcome if they took SSRIs for 3 months after stroke. Those with preservation of these critical areas achieved good recovery of naming regardless of SSRI use. INTERPRETATION: Lesion load in left pSTG and SLF/AF at onset predicts later naming performance. Although based on a small number of patients, our preliminary results suggest outcome might be modulated by SSRIs, but these associations need to be confirmed in a larger randomized controlled trial.

AB - OBJECTIVES: To assess [18 F]AV-1451 tau-PET (positron emission tomography) uptake patterns across the primary progressive aphasia (PPA) variants (logopenic, semantic, and agrammatic), examine regional uptake patterns of [18 F]AV-1451 independent of clinical diagnosis, and compare the diagnostic utility of [18 F]AV 1451, [18 F]-fluorodeoxygluclose (FDG)-PET and MRI (magnetic resonance imaging) to differentiate the PPA variants. METHODS: We performed statistical parametric mapping of [18 F]AV-1451 across 40 PPA patients (logopenic-PPA = 14, semantic-PPA = 13, and agrammatic-PPA = 13) compared to 80 cognitively normal, Pittsburgh compound B-negative controls, age and gender matched 2:1. Principal component analysis of regional [18 F]AV-1451 tau-PET standard uptake value ratio was performed to understand underlying patterns of [18 F]AV-1451 uptake independent of clinical diagnosis. Penalized multinomial regression analyses were utilized to assess diagnostic utility. RESULTS: Logopenic-PPA showed striking uptake throughout neocortex, particularly temporoparietal, compared to controls, semantic-PPA, and agrammatic-PPA. Semantic-PPA and agrammatic-PPA showed milder patterns of focal [18 F]AV-1451 uptake. Semantic-PPA showed elevated uptake (left>right) in anteromedial temporal lobes, compared to controls and agrammatic PPA. Agrammatic-PPA showed elevated uptake (left>right) throughout prefrontal white matter and in subcortical gray matter structures, compared to controls and semantic-PPA. The principal component analysis of regional [18 F]AV-1451 indicated two primary dimensions, a severity dimension that distinguished logopenic-PPA from agrammatic-PPA and semantic-PPA, and a frontal versus temporal contrast that distinguishes agrammatic-PPA and semantic-PPA cases. Diagnostic utility of [18 F]AV-1451was superior to MRI and at least equal to FDG-PET. INTERPRETATION: [18 F]AV-1451binding characteristics differ across the PPA variants and were excellent at distinguishing between the variants. [18 F]AV 1451binding characteristics were as good or better than other brain imaging modalities utilized in clinical practice, suggesting that [18 F]AV-1451 may have clinical diagnostic utility in PPA.

AB - A series of purine-based spin labels was prepared for noncovalent spin-labeling of abasic sites of duplex nucleic acids through hydrogen bonding to an orphan base on the opposing strand and pi-stacking interactions with the flanking bases. Both 1,1,3,3-tetramethylisoindolin-2-yloxyl and 2,2,6,6-tetramethylpiperidine-1 oxyl (TEMPO) were conjugated to either the C2- or C6-position of the purines, yielding nitroxide derivatives of guanine, adenine, or 2,6-diaminopurine. The isoindoline-derived spin labels showed extensive or full binding to abasic sites in RNA duplexes, whereas the TEMPO-derived spin labels showed limited binding. An adenine-derived spin label (5) bound fully at low temperature to abasic sites in both DNA and RNA duplexes when paired with thymine and uracil, respectively, complementing the previously described guanine-derived spin label G, which binds efficiently opposite cytosine. Compound G was also shown to bind to abasic sites in DNA-RNA hybrids, either in the DNA- or the RNA-strand. G showed only a minor flanking-sequence effect upon binding to abasic sites in RNA. When the abasic site was placed close to the end of the RNA duplex, the affinity of the spin label G was reduced; full binding was observed at the fourth position from the duplex end. In summary, spin labels 5 and G showed full binding to abasic sites in both DNA and RNA duplexes and are promising spin labels for structural studies of nucleic acids by pulsed EPR methods. PMID- 29451326 TI - Evaluation of factors contributing to the decline in exclusive breastfeeding at 6 months postpartum: The 2011-2016 National Surveys in Taiwan. AB - BACKGROUND: Since 1992, breastfeeding promotion in Taiwan considerably raised the breastfeeding rates; however, more recent surveillance showed that breastfeeding indicators stagnated or even decreased. METHODS: We analyzed 6 cross-sectional national surveys of 69 159 postpartum women to examine the breastfeeding trends at 6 months postpartum during 2011-2016 in Taiwan and the contributing role of maternal and environmental factors. Data were collected through telephone interviews, using structured questionnaires with randomly selected mothers, who gave birth in those years. A multinomial logistic regression was used to analyze the data. RESULTS: Partial breastfeeding rates at 6 months postpartum increased from 2011 to 2016 (25.4%-45.1%, crude odds ratio [OR] = 1.14 per year of study); however, the rates of exclusive breastfeeding at 6 months postpartum declined (24.5%-14.8%, crude OR = 0.91 per year of study). During this period, increases in maternal age and educational level, employment outside the house, and prepregnancy obesity were observed. Despite a growing number of births at certified baby-friendly hospitals, fewer mothers experienced early skin-to-skin contact and rooming-in in 2016 than in 2011. Adjustment for breastfeeding-related factors did not appreciably change the odds ratio for year of birth. Prenatal intention to breastfeed was most strongly associated with breastfeeding at 6 months postpartum (OR > 5). CONCLUSIONS: Maternal and environmental factors in the study could not explain the decline in exclusive breastfeeding. The decline in exclusive breastfeeding, accompanying the increase in partial breastfeeding, suggests that more support is needed for mothers who intend to breastfeed exclusively. PMID- 29451328 TI - Change and Stability of Emotional Health of Rural Pennsylvania Youth During High School. AB - PURPOSE: Few prior studies have examined change in emotional health of high school students in a rural context. Considering the multifaceted nature of emotional health, this research aims to identify the patterns and explore change and stability of the emotional health of rural Pennsylvania youth. It also investigates the influence of family, peers, school, and the community environment on rural adolescents' emotional health. METHODS: Using panel data from the Rural Youth Education Project, we employed latent transition analysis to examine changes in patterns of rural students' self-reported emotional health from 9th grade to 11th grade (N = 1,294). FINDINGS: Four distinct emotional health subgroups for rural adolescents were identified. Over half of the youth in the sample felt emotionally well, or positive, in both 9th and 11th grades. Roughly 60% of rural youth remained in the same emotional health category from 9th to 11th grade, but a substantial minority experienced change in emotional health. One-fifth reported lower emotional health status in 11th grade, and one fifth indicated more positive emotions in 11th than in 9th grade. We found strong evidence of family, school, community, and peer influences on the emotional health of rural youth in 9th grade. CONCLUSIONS: The results suggest that while a large share of rural youth exhibit positive emotional health and remain positive across their high school years, a substantial share of rural youth experience changing emotional health. The study underscores the important role that family, peers, school, and the community environment play for rural youth's emotional health over time. PMID- 29451327 TI - MicroRNA-365 modulates astrocyte conversion into neuron in adult rat brain after stroke by targeting Pax6. AB - Reactive astrocytes induced by ischemia can transdifferentiate into mature neurons. This neurogenic potential of astrocytes may have therapeutic value for brain injury. Epigenetic modifications are widely known to involve in developmental and adult neurogenesis. PAX6, a neurogenic fate determinant, contributes to the astrocyte-to-neuron conversion. However, it is unclear whether microRNAs (miRs) modulate PAX6-mediated astrocyte-to-neuron conversion. In the present study we used bioinformatic approaches to predict miRs potentially targeting Pax6, and transient middle cerebral artery occlusion (MCAO) to model cerebral ischemic injury in adult rats. These rats were given striatal injection of glial fibrillary acidic protein targeted enhanced green fluorescence protein lentiviral vectors (Lv-GFAP-EGFP) to permit cell fate mapping for tracing astrocytes-derived neurons. We verified that miR-365 directly targets to the 3' UTR of Pax6 by luciferase assay. We found that miR-365 expression was significantly increased in the ischemic brain. Intraventricular injection of miR 365 antagomir effectively increased astrocytic PAX6 expression and the number of new mature neurons derived from astrocytes in the ischemic striatum, and reduced neurological deficits as well as cerebral infarct volume. Conversely, miR-365 agomir reduced PAX6 expression and neurogenesis, and worsened brain injury. Moreover, exogenous overexpression of PAX6 enhanced the astrocyte-to-neuron conversion and abolished the effects of miR-365. Our results demonstrate that increase of miR-365 in the ischemic brain inhibits astrocyte-to-neuron conversion by targeting Pax6, whereas knockdown of miR-365 enhances PAX6-mediated neurogenesis from astrocytes and attenuates neuronal injury in the brain after ischemic stroke. Our findings provide a foundation for developing novel therapeutic strategies for brain injury.

PMID- 29451329 TI - High spatiotemporal resolution bSSFP imaging of hyperpolarized [1-13 C]pyruvate and [1-13 C]lactate with spectral suppression of alanine and pyruvate-hydrate. AB - PURPOSE: The balanced steady-state free precession (bSSFP) acquisition enables high spatiotemporal resolution for hyperpolarized 13 C MRI at 3T but is limited by spectral contamination from adjacent resonances. The purpose of this study was to develop a framework for in vivo dynamic high resolution imaging of hyperpolarized [1-13 C]pyruvate and [1-13 C]lactate generated in vivo at 3T by simplifying the spectrum through the use of selective suppression pulses. METHODS: Spectral suppression pulses were incorporated into the bSSFP sequence for suppression of [1-13 C]alanine and [1-13 C]pyruvate-hydrate signals, leaving only the pyruvate and lactate resonances. Subsequently, the bSSFP pulse width, time-bandwidth, and repetition time were optimized for imaging these dual resonances. RESULTS: The spectral suppression reduced both the alanine and pyruvate-hydrate signals by 85.5 +/- 4.9% and had no significant effect on quantitation of pyruvate to lactate conversion (liver: P = 0.400, kidney: P = 0.499). High resolution (2 * 2 mm2 and 3 * 3 mm2 ) subsecond 2D coronal projections and 3D 2.5 mm isotropic images were obtained in rats and tumor bearing mice with 1.8-5 s temporal resolution, allowing for calculation of lactate-to-pyruvate ratios and kPL . CONCLUSION: The developed framework presented here shows the capability for dynamic high resolution volumetric hyperpolarized bSSFP imaging of pyruvate-to-lactate conversion on a clinical 3T MR scanner.

AB - Despite considerable advances in reconstructive surgery, massive abdominal wall defects continue to pose a significant surgical challenge. We report the case of a 72-year-old morbidly obese female patient with Clostridium septicum-related gas gangrene of the abdominal wall. After multidisciplinary treatment and multiple extensive debridements, a massive full-thickness defect (40 cm * 35 cm) of the right abdominal wall was present. The abdominal contents were covered with a resorbable mesh to prevent evisceration. Finally, the composite defect was successfully reconstructed through a contralateral extended free transverse rectus abdominis myocutaneus (TRAM) flap (50 cm * 38 cm). An arterio-venous loop to the superficial femoral vessels using the great saphenous vein was necessary to allow the flap to reach the defect. Postoperatively, a minor wound healing disorder of the flap was successfully treated with split skin grafting. Six month after surgery, the patient presented with a completely healed flap coverage area and a small abdominal hernia without the need of further surgical revision. This case illustrates the use of a sliding free TRAM flap for closure of a massive abdominal wall defect. PMID- 29451332 TI - Characterizing the Effects of a "Switchable Water" Additive on the Aqueous Solubility of Small Molecules. AB - "Switchable water" is an aqueous solution containing a water-soluble amine additive that exhibits CO2 -switchable properties, such as large changes in ionic strength, by forming an ammonium bicarbonate salt. Switchable water has been used to reversibly "salt-out" organic compounds from water. This study explores the salting out of several compounds in switchable water when CO2 is present and also explores the solubility of small molecules in switchable water, compared to pure water, when CO2 is absent. The results show that organic compounds are generally more soluble in switchable water than pure water in the absence of CO2 , but less soluble in the presence of 1 atm CO2 . Exceptions include carboxylic acids and phenols which, presumably due to their acidity, are more soluble in switchable water than in pure water, even when CO2 is applied. Kirkwood-Buff solvation theory was applied to gain insights into the effects of the amine additive on the aqueous solubility of caffeine. Furthermore, the switchable properties of the additives allow for the preparation of switchable aqueous two-phase systems. PMID- 29451333 TI - Urban-Rural Differences in Aerobic Physical Activity, Muscle Strengthening Exercise, and Screen-Time Sedentary Behavior. AB - PURPOSE: Compared to their urban counterparts, US residents in rural settings face an increased risk of premature mortality and health problems that have been linked to insufficient physical activity (PA) levels. There is limited literature regarding urban-rural differences in adherence to national guidelines for all 3 PA-related behaviors. METHODS: We investigated urban-rural differences in aerobic PA, leisure-time muscle strengthening PA, and leisure screen-time sedentary behavior in a combined data set of the 2011-2014 waves (N = 14,188) of the nationally representative National Cancer Institute's Health Information National Trends Survey. FINDINGS: We found no evidence of a difference between large urban and rural residents' aerobic PA levels. The typical number of weekly bouts of leisure-time muscle strengthening PA was 25% lower for rural residents (incidence rate ratio [IRR] = 0.751, P < .001); this relationship was no longer statistically significant after controlling for potentially confounding covariates. In adjusted models, we found rural residents to engage in 6.6% less daily leisure screen-time sedentary behavior than their large urban counterparts (IRR = 0.934, P = .031). CONCLUSIONS: Taken together with previous literature, these results suggest that rural residents may engage in comparable levels of total PA, but less leisure-time PA, than their urban counterparts. PMID- 29451334 TI - microRNA profiling between Bacillus thuringiensis Cry1Ab-susceptible and resistant European corn borer, Ostrinia nubilalis (Hubner). AB - Transgenic maize hybrids that express insecticidal Bacillus thuringiensis (Bt) crystalline (Cry) protein toxins effectively protect against the European corn borer, Ostrinia nubilalis, a devastating maize pest. Field monitoring and laboratory selections have detected varying levels of O. nubilalis resistance to Cry1Ab toxin. MicroRNAs (miRNAs) are short noncoding RNAs that are involved in post-transcriptional gene regulation. Their potential roles in the evolution of Bt resistance, however, remain largely unknown. Sequencing of small RNA libraries from the midgut of Cry1Ab-susceptible and resistant O. nubilalis larvae resulted in the discovery of 277 miRNAs, including 248 conserved and 29 novel. Comparative analyses of miRNA expression profiles between the laboratory strains predicted 26 and nine significantly up- and down-regulated transcripts, respectively, in the midgut of Cry1Ab resistant larvae. Amongst 15 differentially regulated miRNAs examined by quantitative real-time PCR, nine (60%) were validated as cosegregating with Cry1Ab resistance in a backcross progeny. Differentially expressed miRNAs were predicted to affect transcripts involved in cell membrane components with functions in metabolism and binding, and the putative Bt resistance genes aminopeptidase N and cadherin. These results lay the foundation for future investigation of the potential role of miRNAs in the evolution of Bt resistance. PMID- 29451335 TI - Mesenchymal Stem Cells Protect Against Hypoxia-Ischemia Brain Damage by Enhancing Autophagy Through Brain Derived Neurotrophic Factor/Mammalin Target of Rapamycin Signaling Pathway. AB - Hypoxic-ischemic encephalopathy (HIE) is a serious disease for neonates. However, present therapeutic strategies are not effective enough for treating HIE. Previous study showed that mesenchymal stem cells (MSCs) can exert neuroprotective effects for brain damage, but its mechanism remains elusive. Using in vitro coculture of rat cortical primary neurons and MSCs in HI conditions, we demonstrated that MSCs help increase brain derived neurotrophic factor (BDNF) and autophagy markers (LC3II and Beclin1) in the cultures and decrease cells death (lactate dehydrogenase levels). We demonstrated a similar mechanism using an in vivo rat model of HI in combination with MSCs transplantation. Using a behavioral study, we further showed that MSCs transplantation into the rat brain after HI injury can attenuate behavioral deficits. Finally, we found that the increase in BDNF and autophagy related factors after HI injury combined with MSCs transplantation can be reversed by anti-BDNF treatment and strengthen the point that the protective effects of BDNF work through inhibition of the mammalin target of rapamycin (mTOR) pathway. Collectively, we proposed that coculture/transplantation of MSCs after HI injury leads to increased BDNF expression and a subsequent reduction in mTOR pathway activation that results in increased autophagy and neuroprotection. This finding gives a hint to explore new strategies for treating neonates with HIE. Stem Cells 2018;36:1109-1121. PMID- 29451336 TI - Electronically Unsaturated Three-Coordinate Aluminum Hydride and Organoaluminum Cations. AB - New three-coordinate and electronically unsaturated aluminum hydride [LAlH]+ [HB(C6 F5 )3 ]- (LH=[{(2,6-iPr2 C6 H3 N)P(Ph2 )}2 N]H) and aluminum methyl [LAlMe]+ [MeB(C6 F5 )3 ]- cations have been prepared. The quantitative estimation of Lewis acidity by Gutmann-Beckett method revealed [LAlH]+ [HB(C6 F5 )3 ]- to be better Lewis acid than B(C6 F5 )3 and AlCl3 making these compounds ideal catalysts for Lewis acid-mediated reactions. To highlight that the work is of fundamental importance, catalytic hydroboration of aliphatic and aromatic aldehydes and ketones have been demonstrated. Important steps of the catalytic cycle have been probed by using multinuclear NMR measurements, including successful characterization of the proposed aluminum benzyloxide cationic intermediate, [LAl-O-CH2 Ph]+ [HB(C6 F5 )3 ]- . The proposed catalytic cycle has been found to be consistent with experimental observations and computational studies clearly indicating the migration of hydride from cationic aluminum center to the carbonyl carbon is the rate-limiting step of the catalytic cycle. PMID- 29451337 TI - Eosinophil-derived exosomes contribute to asthma remodelling by activating structural lung cells. AB - BACKGROUND: Eosinophils, a central factor in asthma pathogenesis, have the ability to secrete exosomes. However, the precise role played by exosomes in the biological processes leading up to asthma has not been fully defined. OBJECTIVE: We hypothesized that exosomes released by eosinophils contribute to asthma pathogenesis by activating structural lung cells. METHODS: Eosinophils from asthmatic patients and healthy volunteers were purified from peripheral blood, and exosomes were isolated from eosinophils of asthmatic and healthy individuals. All experiments were performed with eosinophil-derived exosomes from healthy and asthmatic subjects. Epithelial damage was evaluated using primary small airway epithelial cell lines through 2 types of apoptosis assays, that is, flow cytometry and TUNEL assay with confocal microscopy. Additionally, the epithelial repair was analysed by performing wound healing assays with epithelial cells. Functional studies such as proliferation and inhibition-proliferation assays were carried out in primary bronchial smooth muscle cell lines. Also, gene expression analysis of pro-inflammatory molecules was evaluated by real-time PCR on epithelial and muscle cells. Lastly, protein expression of epithelial and muscle cell signalling factors was estimated by Western blot. RESULTS: Asthmatic eosinophil-derived exosomes induced an increase in epithelial cell apoptosis at 24 hour and 48 hour, impeding wound closure. In addition, muscle cell proliferation was increased at 72 hours after exosome addition and was linked with higher phosphorylation of ERK1/2. We also found higher expression of several genes when both cell types were cultured in the presence of exosomes from asthmatics: CCR3 and VEGFA in muscle cells, and CCL26, TNF and POSTN in epithelial cells. Healthy eosinophil-derived exosomes did not exert any effect over these cell types. CONCLUSIONS AND CLINICAL RELEVANCE: Eosinophil-derived exosomes from asthmatic patients participate actively in the development of the pathological features of asthma via structural lung cells. PMID- 29451338 TI - Can dimedone be used to study selenoproteins? An investigation into the reactivity of dimedone toward oxidized forms of selenocysteine. AB - Dimedone is a widely used reagent to assess the redox state of cysteine containing proteins as it will alkylate sulfenic acid residues, but not sulfinic acid residues. While it has been reported that dimedone can label selenenic acid residues in selenoproteins, we investigated the stability, and reversibility of this label in a model peptide system. We also wondered whether dimedone could be used to detect seleninic acid residues. We used benzenesulfinic acid, benzeneseleninic acid, and model selenocysteine-containing peptides to investigate possible reactions with dimedone. These peptides were incubated with H2 O2 in the presence of dimedone and then the reactions were followed by liquid chromatography/electrospray ionization mass spectrometry (LC/ESI-MS). The native peptide, H-PTVTGCUG-OH (corresponding to the native amino acid sequence of the C terminus of mammalian thioredoxin reductase), could not be alkylated by dimedone, but could be carboxymethylated with iodoacetic acid. However the "mutant peptide," H-PTVTGAUG-OH, could be labeled with dimedone at low concentrations of H2 O2 , but the reaction was reversible by addition of thiol. Due to the reversible nature of this alkylation, we conclude that dimedone is not a good reagent for detecting selenenic acids in selenoproteins. At high concentrations of H2 O2 , selenium was eliminated from the peptide and a dimeric form of dimedone could be detected using LCMS and 1 H NMR. The dimeric dimedone product forms as a result of a seleno-Pummerer reaction with Sec-seleninic acid. Overall our results show that the reaction of dimedone with oxidized cysteine residues is quite different from the same reaction with oxidized selenocysteine residues. PMID- 29451339 TI - An Indispensable Role of Androgen Receptor in Wnt Responsive Cells During Prostate Development, Maturation, and Regeneration. AB - Androgen signaling is essential for prostate development, morphogenesis, and regeneration. Emerging evidence indicates that Wnt/beta-catenin signaling also contributes to prostate development specifically through regulation of cell fate determination. Prostatic Axin2-expressing cells are able to respond to Wnt signals and possess the progenitor properties to regenerate prostatic epithelium. Despite critical roles of both signaling pathways, the biological significance of androgen receptor (AR) in Axin2-expressing/Wnt-responsive cells remains largely unexplored. In this study, we investigated this important question using a series of newly generated mouse models. Deletion of Ar in embryonic Axin2-expressing cells impaired early prostate development in both ex vivo and tissue implantation experiments. When Ar expression was deleted in prostatic Axin2-expressing cells at pre-puberty stages, it results in smaller and underdeveloped prostates. A subpopulation of Axin2 expressing cells in prostate epithelium is resistant to castration and, following androgen supplementation, is capable to expand to prostatic luminal cells. Deletion of Ar in these Axin2-expressing cells reduces their regenerative ability. These lines of evidence demonstrate an indispensable role for the Ar in Wnt-responsive cells during the course of prostate development, morphogenesis, and regeneration, which also imply an underlying interaction between the androgen and Wnt signaling pathways in the mouse prostate.

AB - AIM: We aimed to validate the incidence of, risk factors for, and postoperative outcomes of acute kidney injury (AKI) according to the modified Kidney Disease Improving Global Outcomes (m-KDIGO) criteria and compare this criteria with both the pediatric Risk, Injury, Failure, Loss, End-stage disease (pRIFLE) and Acute Kidney Injury Network (AKIN) criteria in infants after cardiac surgery. METHODS: We retrospectively enrolled 145 consecutive infants who underwent open-heart surgery at Kagoshima University Hospital. RESULTS: AKI was present in 55 (37.9%), 111 (75.9%), and 95 (65.5%) patients according to the m-KDIGO, pRIFLE, and AKIN criteria, respectively. Among these, 71.9% of patients pRIFLE Risk patients and 60.5% of AKIN 1 patients were categorised in the 'no-AKI' group according to the m-KDIGO criteria. Low body weight (m-KDIGO odds ratio [OR], 0.73; P = 0.015; pRIFLE OR, 0.66; P = 0.001; AKIN OR 0.69, P = 0.002) and prolonged cross-clamp time (m-KDIGO OR, 1.02;

1000) and/or AT1R-abs (>10UI) were detected by solid-phase assays in pre-KT sera. Multivariable Cox regression models were used to determine independent predictors of outcomes: acute rejection (AR) and graft failure. RESULTS: At transplant, 48 patients were AT1R-abs (-)/DSA (-), 12 AT1R-abs (+)/DSA (-), 9 AT1R-abs (-)/DSA (+) and 7 AT1R-abs (+)/DSA (+). Incidence of acute rejection at 1-year increased from 6% in AT1R-abs (-)/DSA (-), to 35% in AT1R-abs (+)/DSA (-), 47% in AT1R-abs (-)/DSA (+) and 43% in AT1R-abs (+)/DSA (+) (P<0.001). No difference in DSA strength and C1q-binding ability was observed between AT1R-abs (-) /DSA (+) and AT1R-abs (+)/DSA (+) patients. Graft survival at 6-years was the lowest in AT1R-abs (+)/DSA (+) (57%), followed by AT1R-abs (+)/DSA (-) (67%), and higher in AT1R-abs (-)/DSA (-) (94%) and AT1R-abs (-)/DSA (+) (89%) patients (P=0.012). AT1R-abs (+)/DSA (-) (HR=6.41, 95% CI: 1.43 28.68; P=0.015) and AT1R-abs (+)/DSA (+) (HR=7.75, 95% CI: 1.56-38.46; P=0.012) were independent predictors of graft failure. CONCLUSIONS: AR incidence and graft failure were associated with both DSA and AT1R-abs. These results demonstrate a proper negative effect of AT1R-abs on graft outcomes, besides a synergistic one with DSA. Pretransplant AT1R-abs should be acknowledge to better stratify patients' immunological risk. PMID- 29451343 TI - Molecular Tectonics with Di- and Trinuclear Organotin Compounds. AB - Di- and trinuclear organotin(IV) complexes, in which the metal atoms are separated by large aromatic connectors, are useful building blocks for self assembly. This is demonstrated by the preparation of [1+1], [2+2], and [2+3] macrocyclic and cage-type structures in combination with organic aromatic dicarboxylates. The linkage of the metal atoms by organic binders and the option of varying the number of reactive M-X sites generate versatile building blocks enabling molecular tectonics instead of the node-based strategy generally employed in metallo-supramolecular self-assembly. PMID- 29451345 TI - Unsymmetrical, Cyclic Diborenes and Thermal Rearrangement to a Borylborylene. AB - Cyclic diboranes(4) based on a chelating monoanionic benzylphosphine linker were prepared through boron-silicon exchange between arylsilanes and B2 Br4 . Coordination of Lewis bases to the remaining sp2 boron atom yielded unsymmetrical sp3 -sp3 diboranes, which were reduced with KC8 to their corresponding trans diborenes. These compounds were studied with a combination of spectroscopic methods, X-ray diffraction, and DFT calculations. PMe3 -stabilized diborene 6 was found to undergo thermal rearrangement to gem-diborene 8. DFT calculations on 8 reveal a polar boron-boron bond, and indicate that the compound is best described as a borylborylene.

Although this tumor is thought to be derived from primitive respiratory epithelial cells, the characteristics of the precursor cells are still unknown. A 19-year-old woman presented with multiple nodules in the right lung. Partial resection of the right middle lobe was performed, and seven sclerosing pneumocytomas, including four that were microscopic, were detected. The latter showed a simple papillary pattern, and three of them consisted of only round cell-like cells (single population). Interestingly, these round cell-like cells were positive for both p63 and TTF-1, but totally negative for SP-A. On the other hand, the tumor cells of the other four sclerosing pneumocytomas showing a papillary pattern with a dual population, were diffusely positive for TTF-1 and focally positive for SP-A (only in surface cells), but negative or very focally positive for p63. It has been reported that p63-positive stem cell-like cells are present in the distal airway and have potential to differentiate into type II pneumocytes. The immunohistochemical features of these multiple microscopic lesions suggest that the p63-TTF-1 double-positive cells are candidate precursor cells of sclerosing pneumocytoma.

AB - Incorporation of phenanthrene into a hexaphyrin(1.1.1.1.1.0) frame resulted in intramolecular ring fusion, thus giving rise to chiral helicenophyrins. These molecules contain helicene and porphyrin features by incorporating either an aza[5]helicene or heptacyclic S-shaped aza[5]helicene. PMID- 29451347 TI - A rare case of ectopic papillary thyroid carcinoma transformed into squamous cell carcinoma. AB - A rare case of a metastatic ectopic papillary thyroid carcinoma (PTC) of the lung that transformed into a squamous cell carcinoma (SCC) that resembles pulmonary SCC is reported. A subcutaneous ectopic PTC in the left anterior neck area, together with a normal thyroid gland, were excised. The ectopic PTC showed thyroglobulin, TTF-1 and PAX-8 immunoreactivity and a BRAF V600E mutation. During the post-operative follow-up period, a rapidly growing 2 cm nodular lesion in the lower left lobe of the lung was detected. The lung tumor consisted of solid sheets and nests of squamous cells but without the nuclear features of PTC. Neither papillary nor follicular structures of cancer cells were identified. Carcinoma cells were positive for TTF-1, PAX-8, p40, CK14, and p63, while showing a high Ki-67 labeling index and a BRAF V600E mutation. These results support our interpretation of a PTC that originated from ectopic thyroid tissue in the left anterior neck and that developed a lung metastasis showing squamous cell differentiation. PMID- 29451348 TI - Sigmatropic Rearrangements of Hypervalent-Iodine-Tethered Intermediates for the Synthesis of Biaryls. AB - Metal-free dehydrogenative couplings of aryliodanes with phenols to afford 2 hydroxy-2'-iodobiaryls have been developed. This reaction proceeds through ligand exchange on the hypervalent iodine atom followed by a [3,3] sigmatropic rearrangement and with complete regioselectivity. This coupling, in combination with in situ oxidation by mCPBA, enables the convenient conversion of iodoarenes into desirable biaryls. The obtained biaryls have convertible iodo and hydroxy groups in close proximity, and are thus synthetically useful, as exemplified by the controlled syntheses of pi-extended furans and a substituted [5]helicene. DFT calculations clearly revealed that the rearrangement is sigmatropic, with C-C bond formation and I-O bond cleavage proceeding in a concerted manner. Acetic acid, which was found to be the best solvent for this protocol, renders the iodine atom more cationic and thus accelerates the sigmatropic rearrangement. PMID- 29451349 TI - Reply.

AB - Kidney transplantation is the optimal therapy for end-stage renal disease, prolonging survival and reducing spending. Prior economic analyses of kidney transplantation, using Markov models, have generally assumed compatible, low-risk donors. The economic implications of transplantation with high Kidney Donor Profile Index (KDPI) deceased donors, ABO incompatible living donors, and HLA incompatible living donors have not been assessed. The costs of transplantation and dialysis were compared with the use of discrete event simulation over a 10 year period, with data from the United States Renal Data System, University HealthSystem Consortium, and literature review. Graft failure rates and expenditures were adjusted for donor characteristics. All transplantation options were associated with improved survival compared with dialysis (transplantation: 5.20-6.34 quality-adjusted life-years [QALYs] vs dialysis: 4.03 QALYs). Living donor and low-KDPI deceased donor transplantations were cost-saving compared with dialysis, while transplantations using high-KDPI deceased donor, ABO-incompatible or HLA-incompatible living donors were cost-effective (<$100 000 per QALY). Predicted costs per QALY range from $39 939 for HLA-compatible living donor transplantation to $80 486 for HLA-incompatible donors compared with $72 476 for dialysis. In conclusion, kidney transplantation is cost-effective across all donor types despite higher costs for marginal organs and innovative living donor practices. PMID- 29451352 TI - Chronic exposure of mice to low doses of imazalil induces hepatotoxicity at the physiological, biochemical, and transcriptomic levels. AB - Imazalil (IMZ), which is a widely used fungicide, can accumulate in the body and threaten an animal's health. However, this fungicide has adverse effects on aquatic organisms and ultimately affects human health when it leaches into the environment. Our research tried to determine that if IMZ might cause liver damage and its potential to cause-related diseases. In this study, male adult C57BL/6 mice were exposed to 0.1, 0.5, or 2.5 mg/kg body weight IMZ in drinking water for 15 weeks. Then, we evaluated the liver damage at the physiological, biochemical, and transcriptome levels in mice after chronic IMZ exposure. We observed serious ballooning degeneration of hepatocytes in the IMZ-treated groups. And IMZ induced oxidative stress and caused the disorders of bile acid metabolism in mice. In addition, the transcriptome data showed that IMZ has substantial influence on several pathways, including metabolic pathways for drug metabolism, RNA transport, and bile secretion. We further confirmed that the mRNA expression of the key genes involved in oxidative stress and bile acid metabolism were changed of mice exposed to IMZ. Our data suggested that chronic IMZ exposure could induce hepatotoxicity in mice at the physiological, biochemical, and transcriptome levels. PMID- 29451351 TI - Delphinidin induces apoptosis and inhibits epithelial-to-mesenchymal transition via the ERK/p38 MAPK-signaling pathway in human osteosarcoma cell lines. AB - Delphinidin is major anthocyanidin that is extracted from many pigmented fruits and vegetables. This substance has anti-oxidant, anti-inflammatory, anti angiogenic, and anti-cancer properties. In addition, delphinidin strongly suppresses the migration and invasion of various cancer cells during tumorigenesis. Although delphinidin has anti-cancer effects, little is known about its functional roles in osteosarcoma (OS). For these reasons, we have demonstrated the effects of delphinidin on OS cell lines. The effects of delphinidin on cell viability and growth of OS cells were assessed using the MTT assay and colony formation assays. Hoechst staining indicated that the delphinidin-treated OS cells were undergoing apoptosis. Flow cytometry, confocal microscopy, and a western blot analysis also indicated evidence of apoptosis. Inhibition of cell migration and invasion was found to be associated with epithelial-to-mesenchymal transition (EMT), observed by using a wound healing assay, an invasion assay, and a western blot analysis. Furthermore, delphinidin treatment resulted in a profound reduction of phosphorylated forms of ERK and p38. These findings demonstrate that delphinidin treatment suppressed EMT through the mitogen-activated protein kinase (MAPK) signaling pathway in OS cell lines. Taken together, our results suggest that delphinidin strongly inhibits cell proliferation and induces apoptosis. Delphinidin treatment also suppresses cell migration and prevents EMT via the MAPK-signaling pathway in OS cell lines. For these reasons, delphinidin has anti-cancer effects and can suppress metastasis in OS cell lines, and it might be worth using as an OS therapeutic agent. PMID- 29451353 TI - In vitro cytotoxicity assessment of nanodiamond particles and their osteogenic potential. AB - Scaffolds functionalized with nanodiamond particles (nDP) hold great promise with regard to bone tissue formation in animal models. Degradation of the scaffolds over time may leave nDP within the tissues, raising concerns about possible long term unwanted effects. Human SaOS-2 osteoblast-like cells and U937 monoblastoid cells were exposed to five different concentrations (0.002-2 mg/L) of nDP (size range: 2.36-4.42 nm) for 24 h. Cell viability was assessed by impedance-based methods. The differential expression of stress and toxicity-related genes was evaluated by polymerase chain reaction (PCR) super-array, while the expression of selected inflammatory and cell death markers was determined by reverse transcriptase quantitative polymerase chain reaction (RT-qPCR). Furthermore, the expression of osteogenic genes by SaOS-2 cells, alkaline phosphatase activity and the extracellular calcium nodule deposition in response to nDP were determined in vitro. Cells responded differently to higher nDP concentrations (>=0.02 mg/L), that is, no loss of viability for SaOS-2 cells and significantly reduced viability for U937 cells. Gene expression showed significant upregulation of several cell death and inflammatory markers, among other toxicity reporter genes, indicating inflammatory and cytotoxic responses in U937 cells. Nanodiamond particles improved the osteogenicity of osteoblast-like cells with no evident cytotoxicity. However, concentration-dependent cytotoxic and inflammatory responses were seen in the U937 cells, negatively affecting osteogenicity in co cultures. (c) 2018 Wiley Periodicals, Inc.

AB - Kidney Donor Risk Index (KDRI) introduced in 2009 included hepatitis C serologic but not viremic status of the donors. With nucleic acid amplification testing (NAT) now being mandatory, further evaluation of these donors is possible. We conducted a retrospective matched case-control analysis of adult deceased donor kidney transplants performed between December 5, 2014 to December 31, 2016 with the KDRI score and hepatitis C virus antibody (HCV Ab) and NAT testing status obtained from the United Network for Organ Sharing database. The 205 aviremic HCV Ab+ NAT - kidney transplants were compared to KDRI matched control kidneys that were HCV Ab-NAT-. The aviremic HCV kidneys were recovered from donors who were significantly younger, more likely to be white, and less likely to have hypertension and diabetes. The majority of the recipients of the aviremic HCV kidneys when compared to matched controls were HCV positive: 90.2% vs 4.3%. The recipients were significantly older, were on dialysis for a shorter time, and were transplanted sooner. The graft survival of aviremic HCV kidneys was similar (P < .08). If the HCV status of the aviremic kidneys was assumed to be negative, 122 more kidneys could have been allocated to patients with estimated posttransplant survival <20. Seven kidneys would no longer have Kidney Donor Profile Index >85%. Further policies might consider these findings to appropriately allocate these kidneys. PMID- 29451355 TI - A Critical Evaluation of In Vitro Hesperidin 2S Bioavailability in a Model Combining Luminal (Microbial) Digestion and Caco-2 Cell Absorption in Comparison to a Randomized Controlled Human Trial. AB - SCOPE: Bioavailability strongly determines polyphenol bioactivity, and is strongly influenced by food matrix, enzymatic and microbial degradation, and gastrointestinal absorption. To avoid human trials for pre-screening of polyphenol bioavailability, studies have focused on in vitro model development. Nevertheless, their predictive value for bioavailability can be questioned. METHOD AND RESULTS: We used the orange flavonoid hesperidin 2S to validate a model combining digestion in the simulator of the human intestinal microbial ecosystem (SHIME) and Caco-2 cell transport, with a human intervention study. In vitro, hesperidin was resistant to degradation in the stomach and small intestine, but was rapidly deconjugated on reaching the proximal colon. Extensive and colon-region-specific degradation to smaller phenolics was observed. Hydrocaffeic and dihydroisoferulic acid accumulated in proximal, and hydroferulic acid in distal colon. Caco-2 transport was the highest for dihydroisoferulic acid. In humans, plasma and urine hesperetin-glucuronide levels increased significantly, whereas the impact on small phenolics was limited. CONCLUSIONS: In the combined in vitro model, smaller phenolics strongly accumulated, whereas in humans, hesperetin conjugates were the main bioavailable compounds. Future in vitro model development should focus on simulating faster polyphenol absorption and elimination of smaller phenolics to improve their predictive value of in vivo polyphenol bioavailability.

PMID- 29451357 TI - Assessing normal values for the FACE-Q rhinoplasty module: An observational study. AB - OBJECTIVES: The goal of this study was to determine normal values for the FACE-Q rhinoplasty module. DESIGN: A prospective monocentric observational cohort study. SETTING: We tested FACE-Q Satisfaction with Nose and Satisfaction with Nostrils in two groups of patients, seeking or not a rhinoplasty. PARTICIPANTS: One hundred and four patients were included in the study, fifty-two in each group. MAIN OUTCOME MEASUREMENTS: Primary outcome was to identify possible cutting scores to establish normal values for each of the FQRM questionnaires. RESULTS: Regarding the Satisfaction with Nose scale, there was a statistically significant difference between the two groups (P < .001). Area under the ROC curve was 0.964 (95% CI = 0.931-0.997). Forty-seven points was the value presenting the best Youden index (sensitivity = 96.2%, specificity = 86.5%). Regarding the Satisfaction with Nostrils scale, there was a statistically significant difference between the two groups (P < .001). Area under the ROC curve was 0.820 (95% CI = 0.741-0.899). Sixty-four points was the value presenting the best Youden index (sensitivity = 94.2%, specificity = 53.8%). CONCLUSION: This is the first study to generate normative data for the FACE-Q rhinoplasty module. The findings presented here have important implications for future clinical care and research. The definition of a normal score can help practitioners to better analyse their patients and to support a therapeutic indication. PMID- 29451359 TI - Assessment of narrative writing by Persian-speaking students with hearing impairments. AB - OBJECTIVE: Previous studies have highlighted that narrative skill is critical to the development of the literacy skills by children. Children with cochlear implants (CI) and hearing aids (HA) may have problems in narrative development compared to peers with healthy hearing (HH). There is no exact data about the narrative writing ability of Persian-speaking students who are hearing-impaired. This study was undertaken to compare the microstructure and macrostructure scores for narrative writing of Persian-speaking students who are hearing-impaired and peers with HH. DESIGN: This was a cross-sectional descriptive-analytical study. SETTING: The subjects were recruited from elementary schools in the city of Tehran. PARTICIPANTS: A total of 144 elementary school students were participated. OUTCOME MEASURES: The written narratives were elicited using a wordless pictorial storybook story. Three-way ANOVA with post hoc adjusted Bonferroni test was applied to determine the main effects and interactions of grounded variables on the microstructure and macrostructure components of narrative writing. RESULTS: No significant differences were observed in the macrostructure components of narrative writing between hearing-impaired and HH students. Factors analysis showed that the 4th grade HH students had significantly the highest scores, and the 3rd grade HA students had significantly the lowest scores in microstructure components of narrative writing. CONCLUSION: The findings revealed that hearing-impaired students similarly to their HH peers can transmit the main idea (macrostructure) of narrative writing, but show critical difficulties when using complete grammatical elements (microstructures) to form sentences to convey the idea in the narrative. PMID- 29451358 TI - Electronic Structure Characterization of Cross-Linked Sulfur Polymers. AB - Cross-linked polymers of elemental sulfur are of potential interest for electronic applications as they enable facile thin-film processing of an abundant and inexpensive starting material. Here, we characterize the electronic structure of a cross-linked sulfur/diisopropenyl benzene (DIB) polymer by a combination of soft and hard X-ray photoelectron spectroscopy (SOXPES and HAXPES). Two different approaches for enhancing the conductivity of the polymer are compared: the addition of selenium in the polymer synthesis and the addition of lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) during film preparation. For the former, we observe the incorporation of Se into the polymer structure resulting in a changed valence-band structure. For the latter, a Fermi level shift in agreement with p-type doping of the polymer is observed and also the formation of a surface layer consisting mostly of TFSI anions. PMID- 29451360 TI - Defining Optimal Surgical Treatment for Recurrent Hepatocellular Carcinoma: A Propensity Score Matched Analysis. AB - Salvage liver transplantation (sLT) and repeated resection (RR) are effective treatments for recurrent hepatocellular carcinoma (HCC), and comparisons of the oncological outcomes between these 2 modalities were scarce. Consecutive patients admitted for either sLT or RR for recurrent HCC were recruited. All patients in the present series received either prior hepatectomy, ablative therapy, or both before RR or sLT. Patient demographic, perioperative, and outcome data were analyzed. A survival analysis was performed after propensity score matching. There were 277 eligible patients recruited, and 67 and 210 of them underwent sLT and RR, respectively. Significant differences in preoperative hemoglobin, albumin, Model of End-Stage Liver Disease (MELD) score, and tumor number were found between the sLT and RR groups. After 1:3 propensity score matching, there were 36 sLT and 108 RR patients for comparison. The median age, MELD, alpha fetoprotein, and tumor size and number of the matched population were 57 years, 7.5, 16 ng/mL, 2.5 cm, and 1, respectively. There was no difference in the hospital mortality and complication rate (Clavien IIIa or above) between the groups. The recurrence rate after RR was significantly higher than for the patients who received sLT (72.2% versus 27.8%; P < 0.001). Following RR, 3 patients received liver transplantation for further recurrence, and 54.6% of the patients developed nontransplantable recurrence. The 5-year disease-free survival (DFS) and overall survival (OS) were both superior in the sLT group (DFS, 71.6% versus 32.8%, P < 0.001; OS, 72.8% versus 48.3%, P = 0.007). In conclusion, sLT is superior to RR for treatment of recurrent HCC in terms of DFS and OS. The high rate of nontransplantable recurrence after reresection underscores the importance of timely sLT. PMID- 29451361 TI - Development of a Focused Library of Triazole-Linked Privileged-Structure-Based Conjugates Leading to the Discovery of Novel Phenotypic Hits against Protozoan Parasitic Infections. AB - Protozoan infections caused by Plasmodium, Leishmania, and Trypanosoma spp. contribute significantly to the burden of infectious diseases worldwide, causing severe morbidity and mortality. The inadequacy of available treatments calls for cost- and time-effective drug discovery endeavors. To this end, we envisaged the triazole linkage of privileged structures as an effective drug design strategy to generate a focused library of high-quality compounds. The versatility of this approach was combined with the feasibility of a phenotypic assay, integrated with early ADME-tox profiling. Thus, an 18-membered library was efficiently assembled via Huisgen cycloaddition of phenothiazine, biphenyl, and phenylpiperazine scaffolds. The resulting 18 compounds were then tested against seven parasite strains, and counter-screened for selectivity against two mammalian cell lines. In parallel, hERG and cytochrome P450 (CYP) inhibition, and mitochondrial toxicity were assessed. Remarkably, 10-((1-(3-([1,1'-biphenyl]-3-yloxy)propyl)-1H 1,2,3-triazol-5-yl)methyl)-10H-phenothiazine (7) and 10-(3-(1-(3-([1,1'-biphenyl] 3-yloxy)propyl)-1H-1,2,3-triazol-4-yl)propyl)-10H-phenothiazine (12) showed respective IC50 values of 1.8 and 1.9 MUg mL-1 against T. cruzi, together with optimal selectivity. In particular, compound 7 showed a promising ADME-tox profile. Thus, hit 7 might be progressed as an antichagasic lead. PMID- 29451362 TI - Simultaneous Multiple MS Binding Assays for the Dopamine, Norepinephrine, and Serotonin Transporters. AB - In this work, we present label-free, mass-spectrometry-based binding assays (MS Binding Assays), targeting the human dopamine, norepinephrine, and serotonin transporters (hDAT, hNET, and hSERT) in simultaneous binding experiments. Using a validated LC-ESI-MS/MS method for quantification of the selective dopamine transporter inhibitor (R,R)-4-(2-benzhydryloxyethyl)-1-(4-fluorobenzyl)piperidin 3-ol ((R,R)-D-84), the selective norepinephrine transporter inhibitor (S,S) reboxetine, and the selective serotonin reuptake inhibitor (S)-citalopram, binding affinities at the three monoamine transporters could be characterized simultaneously in a single binding experiment. The performed simultaneous saturation and competition experiments yielded results that are in good accordance with those determined in MS Binding Assays addressing the monoamine transporters individually. The results obtained from this study underscore the potential of MS Binding Assays for simultaneous affinity determination at different targets, which is difficult to accomplish with conventional radioligand binding assays.

AB - Marine medaka (Oryzias melastigma) is considered to be a useful fish model for marine and estuarine ecotoxicology studies and has good potential for field-based population genomics because of its geographical distribution in Asian estuarine and coastal areas. In this study, we present the first whole-genome draft of O. melastigma. The genome assembly consists of 8,602 scaffolds (N50 = 23.737 Mb) and a total genome length of 779.4 Mb. A total of 23,528 genes were predicted, and 12,670 gene families shared with three teleost species (Japanese medaka, mangrove killifish and zebrafish) were identified. Genome analyses revealed that the O. melastigma genome is highly heterozygous and contains a large number of repeat sequences. This assembly represents a useful genomic resource for fish scientists. PMID- 29451364 TI - Prevalence of celiac disease in adult Chinese patients with diarrhea-predominant irritable bowel syndrome: A prospective, controlled, cohort study. AB - OBJECTIVE: Celiac disease is a chronic inflammatory enteropathy with a symptom spectrum similar to that of irritable bowel syndrome (IBS). It is a common but largely undiagnosed condition in the Western countries. However, it is extremely rare among Chinese individuals, and few studies have investigated its prevalence in China. The aim was to determine the prevalence of celiac disease in patients with IBS who were diagnosed using the Rome III criteria in a single center of northern China. METHODS: This was a single-center, prospective, controlled cohort study performed in Qilu Hospital involving 246 patients with IBS and 246 healthy controls. Blood samples were drawn to assess serum tissue transglutaminase immunoglobulin A (tTg-IgA). Patients with a positive or equivocal tTg-IgA (>=15 U/mL) were subjected to probe-based confocal laser endomicroscopy (pCLE) and duodenal biopsy to confirm celiac disease. RESULTS: Altogether 12 (4.9%) patients with IBS and two (0.8%) healthy controls were positive or equivocal for serum tTg IgA. Of these, five patients with IBS underwent pCLE and a targeted biopsy; all were histopathologically found to have celiac disease, although one was eventually diagnosed with lymphoma. After implementation of a gluten-free diet, seven patients serologically positive for IBS showed clinical improvement, thus our study illustrated a minimum prevalence of 2.85% of celiac disease among patients with IBS in our center. CONCLUSIONS: Celiac disease is not rare in Chinese individuals, particularly among those with IBS. Therefore, it should receive higher attention in clinical practice in China. PMID- 29451365 TI - The genome of the freshwater monogonont rotifer Brachionus calyciflorus. AB - Monogononta is the most speciose class of rotifers, with more than 2,000 species. The monogonont genus Brachionus is widely distributed at a global scale, and a few of its species are commonly used as ecological and evolutionary models to address questions related to aquatic ecology, cryptic speciation, evolutionary ecology, the evolution of sex and ecotoxicology. With the importance of Brachionus species in many areas of research, it is remarkable that the genome has not been characterized. This study aims to address this lacuna by presenting, for the first time, the whole-genome assembly of the freshwater species Brachionus calyciflorus. The total length of the assembled genome was 129.6 Mb, with 1,041 scaffolds. The N50 value was 786.6 kb, and the GC content was 24%. A total of 16,114 genes were annotated with repeat sequences, accounting for 21% of the assembled genome. This assembled genome may form a basis for future studies addressing key questions on the evolution of monogonont rotifers. It will also provide the necessary molecular resources to mechanistically investigate ecophysiological and ecotoxicological responses. PMID- 29451366 TI - Near-infrared bone densitometry: A feasibility study on distal radius measurement. AB - Osteoporosis, defined as decreased bone mineral density (BMD), poses patients in dangers for fracture risk and has become a major public health problem worldwide because of is associated morbidity, mortality and costs. Without doubt, early detection and timely intervention are important to successfully manage osteoporosis and its associated complications. The dual-energy x-ray absorptiometry (DXA) is the most popular and standard method to measure BMD. However, limitations including radiation exposure and availability restrict its application for osteoporosis screening among general population. In this study, we developed a simple method to detect human distal radius bone density based on near infrared (NIR) image system. Among 10 volunteers (including 5 young and 5 elderly participants) receiving bone density measurement using our NIR image system at the ultradistal part of bilateral distal radius, we demonstrated a strong correlation between the optical attenuation and BMD measured with DXA, which may facilitate predicting bone density status. We hope our potential NIR image system may open a new avenue for development of osteoporosis screening facilities and help in prevention of osteoporosis related fracture and its associated complications in the near future. Pearson's correlations between BMD values from the DXA and light intensity of NIR system. PMID- 29451367 TI - Association between famine exposure in early life and type 2 diabetes mellitus and hyperglycemia in adulthood: Results from the China Health And Retirement Longitudinal Study (CHARLS). AB - BACKGROUND: Studies have revealed the association between famine in early life and type 2 diabetes mellitus (T2DM) in adulthood. However, studies on the Great Chinese Famine were not conducted nationwide. Because of regional variations in the severity of this famine, the results of regional studies are limited. This study explored associations between famine and T2DM in adulthood in a nationwide study. METHODS: The present study was performed on 7262 participants who were born between 1 October 1949 and 1 July 1966 using baseline data collected for the China Health And Retirement Longitudinal Study (CHARLS) in 2011. Participants were divided according to birthdate into cohorts with fetal, late, middle, and early childhood exposure and no exposure to famine. Logistic regression models were used to analyze the association between famine exposure in early life and the risk of T2DM and hyperglycemia in adulthood. RESULTS: For females, the risk of hyperglycemia was higher for famine-exposed than not exposed cohort (odds ratios [OR] 1.34 and 95% confidence intervals [CIs]: 1.34 [1.04-1.74], 1.48 [1.15 1.90], 1.38 [1.06-1.79], and 1.57 [1.25-1.98] for fetal, early, middle, and late childhood exposure, respectively), and this association was even stronger in female participants who lived in rural areas before the age of 16 years. In males, the risk of T2DM was lower for the early and late childhood exposure than no exposure cohorts (OR [95% CIs]: 0.65 [0.49-0.86] and 0.74 [0.56-0.98], respectively). [Correction added on 23 July 2018, after first online publication: Parts of the above 'Results' section have been corrected to interchange the citation of the words 'late' and 'early'.] CONCLUSION: Exposure to famine during early life can increase the risk of hyperglycemia in female adults, but may decrease the risk of T2DM in males. PMID- 29451368 TI - Public health response to an imported case of canine melioidosis. AB - Melioidosis in humans presents variably as fulminant sepsis, pneumonia, skin infection and solid organ abscesses. It is caused by Burkholderia pseudomallei, which in the United States is classified as a select agent, with "potential to pose a severe threat to both human and animal health, to plant health or to animal and plant products" (Federal Select Agent Program, http://www.selectagents.gov/, accessed 22 September 2016). Burkholderia pseudomallei is found in soil and surface water in the tropics, especially South East Asia and northern Australia, where melioidosis is endemic. Human cases are rare in the United States and are usually associated with travel to endemic areas. Burkholderia pseudomallei can also infect animals. We describe a multijurisdictional public health response to a case of subclinical urinary B. pseudomallei infection in a dog that had been adopted into upstate New York from a shelter in Thailand. Investigation disclosed three human contacts with single, low-risk exposures to the dog's urine at his residence, and 16 human contacts with possible exposure to his urine or culture isolates at a veterinary hospital. Contacts were offered various combinations of symptom/fever monitoring, baseline and repeat B. pseudomallei serologic testing, and antibiotic post-exposure prophylaxis, depending on the nature of their exposure and their personal medical histories. The dog's owner accepted recommendations from public health authorities and veterinary clinicians for humane euthanasia. A number of animal rescue organizations actively facilitate adoptions into the United States of shelter dogs from South-East Asia. This may result in importation of B. pseudomallei into almost any community, with implications for human and animal health.

PMID- 29451371 TI - Young's Modulus and Load Complexity: Modeling Their Effects on Proximal Femur Strain. AB - Finite element analysis (FEA) is a powerful tool for evaluating questions of functional morphology, but the application of FEA to extant or extinct creatures is a non-trivial task. Three categories of input data are needed to appropriately implement FEA: geometry, material properties, and boundary conditions. Geometric data are relatively easily obtained from imaging techniques, but often material properties and boundary conditions must be estimated. Here we conduct sensitivity analyses of the effect of the choice of Young's Modulus for elements representing trabecular bone and muscle loading complexity on the proximal femur using a finite element mesh of a modern human femur. We found that finite element meshes that used a Young's Modulus between 500 and 1,500 MPa best matched experimental strains. Loading scenarios that approximated the insertion sites of hip musculature produced strain patterns in the region of the greater trochanter that were different from scenarios that grouped muscle forces to the superior greater trochanter, with changes in strain values of 40% or more for 20% of elements. The femoral head, neck, and proximal shaft were less affected (e.g. approximately 50% of elements changed by 10% or less) by changes in the location of application of muscle forces. From our sensitivity analysis, we recommend the use of a Young's Modulus for the trabecular elements of 1,000 MPa for the proximal femur (range 500-1,500 MPa) and that the muscular loading complexity be dependent on whether or not strains in the greater trochanter are the focus of the analytical question.

AB - Cardiac sympathetic denervation (CSD) to treat ventricular arrhythmias (VAs) requires transection at the middle or lower third of stellate (cervicothoracic) ganglia (SG). However, the morphological appearance of the adult SG and distribution of neuronal somata within it are not well described. To determine the morphology of left and right SG (LSG and RSG) and the distribution of somata within. LSG and RSG (n = 28) from 14 embalmed adult cadavers were dissected intact. Weight, volume, height, morphologic appearance, relationship between C8 and T1 ganglia (which form the SG) were determined, along with histology. Demographics, history of cardiac disease, and cause of death were also reviewed. Mean age of the subjects was 76 +/- 13 years, and 5/14 were male. Three distinct morphologies of SG were identified: fusiform-rounded; fusiform-elongated; and bilobed. RSG and LSG did not differ in weight or volume. RSG were longer than LSG (2.05 +/- 0.28 cm vs. 1.66 +/- 0.47 cm, P = 0.024). Bilobed morphology was most common in RSGs (8/14), while fused, elongated was most common in LSG (8/14). RSGs lacked fused, rounded appearance, while 28.6% of LSG appeared as such. Histologically, one focus of somata was seen in fused rounded ganglia, while fused elongated SG had somata distributed throughout. Bilobed SG demonstrated two foci of somata, with the interconnecting stalk containing sparse somata. SG appears in three major forms and contains varying distributions of somata. Larger studies are warranted to define the relationship between gross anatomy and distribution of neuronal somata to improve the efficacy of CSD in treating VAs. Anat Rec, 2018.

AB - This study characterizes the complex structural and functional elements of the female rat urethra that may be involved in controlling urethral closure and continence. Urethras were dissected from female Sprague-Dawley rats (N = 12) euthanized by pentobarbital overdose. Tissues were fixed (4% paraformaldehyde), frozen, and sectioned (8 MUm) for light microscopy and immunohistochemistry. Antibodies were used to detect immunoreactivity to calcitonin gene related peptide, nitric oxide synthase, vesicular acetylcholine transporter, and tyrosine hydroxylase. Measurements of urethral wall compliance were taken along its length and in different axes using a closed ended catheter with a circular aperture. The bladder neck and proximal urethra are characterized by a highly folded epithelium and lamina propria. A smooth muscle layer is apparent but not pronounced. Distal to this region the smooth muscle layer thickens and forms the body of the internal sphincter, which has a complex innervation. In the mid urethra, the smooth muscle is thickened resulting in a luminal protrusion, producing an occlusion of the lumen. The structure of the distal urethra is different. The epithelium has few folds and, immediately below the lamina propria large thin walled vascular lacunae can be found. Measurements of the urethral wall compliance demonstrate distinct regional differences with proximal and distal specialisations. These variations, which correlate with muscular and vascular elements, suggest the operation of discrete systems, hence effecting urethral closure during filling. An understanding of these systems may yield insights into urethral pathology and direct approaches to develop pharmacological interventions to promote continence. Anat Rec, 2018.

AB - OBJECTIVE: Chlamydia trachomatis is the most prevalent bacteria causing sexually transmitted infections. In women, this infection can cause cervicitis and urethritis, although it's usually asymptomatic. The aim of this study was to investigate the prevalence of C. trachomatis in women attending the lab Instituto de Prevision Social and detect the genotypes. METHODS: Endocervical samples from 505 symptomatic and asymptomatic women were assayed. It was determined the presence of C. trachomatis by PCR through amplification of a fragment of the cryptic plasmid. Positive samples were genotyped by the partial amplification of the ompA gene and analyzed phylogenetically. RESULTS: Forty-three positive samples were detected to infection with C. trachomatis, obtaining a prevalence of 8.5% (IC 95%: 6.4-11.3%). The prevalence of C. trachomatis was higher in women with vaginal symptoms [11.3% (30/265) vs. 5.4% (13/240)] (p = 0.018), as well as in women under 26 year-old [11.5% (28/244) vs. 6.2% (15/246)] (p = 0.021). Based on phylogenetic analysis, it was observed that 62% of the samples were genotype E, 15% genotype J, 15% genotype D, and 8% genotype F. CONCLUSIONS: This work is the first contribution on the molecular epidemiology of C. trachomatis in the Misiones province, Argentina, which shows the rate of prevalence of this bacterium and offers information on circulating genotypes.

PMID- 29451376 TI - [Phage therapy, an alternative to antibiotic therapy?)]. AB - Bacteriophages are viruses that infect and parasitize bacteria. They can present a lytic cycle that determines the lysis of the infected bacteria. Each phage is specific to a particular bacterial genus or species. The current increase in the incidence of antibiotic resistance in human bacteria has favored the study of phages as a therapeutic alternative (phage therapy). Previous studies have shown the efficacy of these elements in cutaneous and intestinal infections. Different clinical trials are underway to establish the safety, reactogenicity and therapeutic efficacy of multiple phage. Being active elements, phages must undergo rigorous quality controls to ensure the absence of undesirable effects. The bacterial lysis that they cause is of a magnitude inferior to the one provoked by the antibiotics. As problems to be solved in the future are the possibility of using mixtures of several phages, establish the ideal route of administration and modify them genetically to deactivate bacterial resistance genes.

AB - Seagrasses in coastal environments have been threatened by increased human activities; these have negatively altered processes and environmental services, and have decreased grassland areas. The aim of this study was to generate knowledge of Thalassia testudinumdistribution, state of the structure and fragmentation level in two reefs of the Veracruz Reef System NationalPark (PNSAV). Two different reefs were selected: Sacrificios in the North and near the coast, and Cabezo inthe South and away from the coast. Shoot-specific and area specific characteristics of submerged macrophytesmeadows present were determined, and four morpho-functional groups were identified. Significant differencesbetween plant coverage were tested through nonparametric ANOVA, Kruskal-Wallis test. A supervised classificationof spatial high-resolution image verified with field data was performed (55 Sacrificios and 290 Cabezo).The fragmentation level was calculated using landscape metrics, class level and thematic maps were made basedon four covers. The meadows were dominated by Thalassia testudinum; maximum densities were 208 shoot/m2in Cabezo, and 176 shoot/m2 in Sacrificios. Cabezo presented grasses with short (9 cm) and thin leaves (0.55cm) on average; while Sacrificios showed longer (23.5 cm) and thicker (1 cm) leaves. Sacrificios showed lowerfragmentation degree than Cabezo; in both cases, the vegetation cover fragmentation corresponded to less than50 %. Although Cabezo reef presents further fragmentation, which creates a large number of microenvironments,being recognized for its importance as recruitment area. This work serves as a baseline for the creationof an adequate management plan (formation of a core area of Cabezo). It is necessary to complement this workwith new efforts for the recognition of seagrass prairies in all PNSAV reefs, as well as periodic monitoring andrecognition of ecosystem services. .

AB - The American oyster, Crassostrea virginica, is one of the most important economiccoastal fishery activities in Mexico. As for other bivalve molluscs, its sustainability is based on healthypopulations, and additional information on current reproductive cycles, will reinforce local management strategies.The objective of this study was to evaluate the effect of temperature and salinity on the gonadal developmentstages in both sexes and in two size groups (40-60 mm and >= 61 mm) of C. virginica from TamiahuaLagoon, Gulf of Mexico. Monthly surveys of 90 organisms were undertaken, for a yearly total of 1 080 oysterssampled from the lagoon in 2011. Both field and laboratory work used standard procedures. Our results showedthat reproduction was continuous in both sexes, but some peaks of the reproductive cycle were observed alongthe year. Peaks registered from January to July were for gametogenesis; those of June and September were formature individuals; and in January, February, and from September to December, for spawning/spent oysters.Maturity of females of both range sizes was positively correlated with temperature, but not for males. For spawning,spent individuals, males of sizes >= 61 mm were positively correlated with salinity, whereas smaller males(40-60 mm) and females of both sizes, did not show any correlation. In this study, we observed that temperatureand salinity had a different effect in the reproduction of the American oyster of different sizes and sexes ofTamiahua lagoon.

AB - Pine plantations in the tropics are often employed to recondition eroded slopes from mudslides, as thePinus caribaea plantation that shields the Universidad Simon Bolivar campus in Caracas (Venezuela). However,mismanagement of this plantation has led to its rapid degradation. The best option to maintain the protectiveservice is to restore the plantation and direct its successional trajectory towards the neighbouring montane forest.Through experimental manipulation, we aimed to determine which factors block secondary succession and toinvestigate their effects. Within the experimental constraints imposed by the plantation small area, we analysedthe effects of light and fertility limitation, litter accumulation and access to seed on plantation restoration. Lightavailability was manipulated by clearing and thinning three 800 m2 main plots. Fertilization and litter removalwas applied to sub-plots within the light plots. Soils were analysed, microclimate was monitored and, for fouryears, stem density, species richness and basal area were tallied. Our results showed that light accessibility wasthe main factor deterring the successional trajectory of the plots, with varying grades of interaction with thesub-treatments. By the end of the fourth year, the cleared plot showed the largest responses in all traits (triplicatingstem density and basal area and >20 times higher species richness). The main colonizers were Crotonmegalodendron, Ocotea fendleri, and Clusia spp. all dominant trees in the nearby native forest. We concludedthat the results of this pioneer study, showed that small clearings, repeated in 3-4 year cycles are appropriatefor similar restoration schemes. This procedure would create a mosaic of vegetation patches at different successionalstages while protecting the slopes from erosion and increasing local biodiversity.

AB - Formic acid is corrosive, and a sensitive and selective sensor could be useful in industrial, medical, and environmental settings. We present a chemiresistor for detection of formic acid composed of single-walled carbon nanotubes (CNTs) and nickel bis( ortho-diiminosemiquinonate) (1), a planar metal complex that can act as a ditopic hydrogen-bonding selector. Formic acid is detected in concentrations as low as 83 ppb. The resistance of the material decreases on exposure to formic acid, but slightly increases on exposure to acetic acid. We propose that 1 assists in partial protonation of the CNT by formic acid, but the response toward acetic acid is dominated by inter-CNT swelling. This technology establishes CNT based chemiresistive discrimination between formic and acetic acid vapors. PMID- 29451381 TI - From a Highly Disordered to a Metastable State: Uncovering Insights of alpha Synuclein. AB - alpha-Synuclein (alphaS) is a major constituent of Lewy bodies, the insoluble aggregates that are the hallmark of one of the most prevalent neurodegenerative disorders, Parkinson's disease (PD). The vast majority of experiments in vitro and in vivo provide extensive evidence that a disordered monomeric form is the predominant state of alphaS in water solution, and it undergoes a large-scale disorder-to-helix transition upon binding to vesicles of different types. Recently, another form, tetrameric, of alphaS with a stable helical structure was identified experimentally. It has been shown that a dynamic intracellular population of metastable alphaS tetramers and monomers coexists normally; and the tetramer plays an essential role in maintaining alphaS homeostasis. Therefore, it is of interest to know whether the tetramer can serve as a means of preventing or delaying the start of PD. Before answering this very important question, it is, first, necessary to find out, on an atomistic level, a correlation between tetramers and monomers; what mediates tetramer formation and what makes a tetramer stable. We address these questions here by investigating both monomeric and tetrameric forms of alphaS. In particular, by examining correlations between the motions of the side chains and the main chain, steric parameters along the amino-acid sequence, and one- and two-dimensional free-energy landscapes along the coarse-grained dihedral angles gamma and delta and principal components, respectively, in monomeric and tetrameric alphaS, we were able to shed light on a fundamental relationship between monomers and tetramers, and the key residues involved in mediating formation of a tetramer. Also, the reasons for the stability of tetrameric alphaS and inability of monomeric alphaS to fold are elucidated here. PMID- 29451383 TI - Arsenic Speciation in Mekong Delta Sediments Depends on Their Depositional Environment. AB - Arsenic contamination in groundwater is pervasive throughout deltaic regions of Southeast Asia and threatens the health of millions. The speciation of As in sediments overlying contaminated aquifers is poorly constrained. Here, we investigate the chemical and mineralogical compositions of sediment cores collected from the Mekong Delta in Vietnam, elucidate the speciation of iron and arsenic, and relate them to the sediment depositional environment. Gradual dissolution of ferric (oxyhydr)oxides with depth is observed down to 7 m, corresponding to the establishment of reducing conditions. Within the reduced sediment, layers originating from marine, coastal or alluvial depositional environments are identified and their age is consistent with a late Holocene transgression in the Mekong Delta. In the organic matter- and sulfur-rich layers, arsenic is present in association with organic matter through thiol-bonding and in the form of arsenian pyrite. The highest arsenic concentration (34-69 ppm) is found in the peat layer at 16 m and suggests the accumulation of arsenic due to the formation of thiol-bound trivalent arsenic (40-55%) and arsenian pyrite (15 30%) in a paleo-mangrove depositional environment (~8079 yr BP). Where sulfur is limited, siderite is identified, and oxygen- and thiol-bound trivalent arsenic are the predominant forms. It is also worth noting that pentavalent arsenic coordinated to oxygen is ubiquitous in the sediment profile, even in reduced sediment layers. But the identity of the oxygen-bound arsenic species remains unknown. This work shows direct evidence of thiol-bound trivalent arsenic in the Mekong Delta sediments and provides insight to refine the current model of the origin, deposition, and release of arsenic in the alluvial aquifers of the Mekong Delta.

Here, we report how the photomechanical twisting of 1,2-bis(2 methyl-5-phenyl-3-thienyl)perfluorocyclopentene (1a) crystals depends on illumination direction. The ribbon-like crystal of 1a could be successfully prepared by a sublimation method. The ribbon crystal exhibited reversible photomechanical crystal twisting upon alternating irradiation with ultraviolet (UV) and visible light. Moreover, changing the UV illumination direction with respect to the crystal resulted in different twisting modes, ranging from helicoid to cylindrical. Control of photomechanical crystal deformation by illumination direction provides a convenient and useful way to generate a variety of photomechanical motions from a single crystal. PMID- 29451384 TI - Highly Elastic Biodegradable Single-Network Hydrogel for Cell Printing. AB - Cell printing is becoming a common technique to fabricate cellularized printed scaffold for biomedical application. There are still significant challenges in soft tissue bioprinting using hydrogels, which requires live cells inside the hydrogels. Moreover, the resilient mechanical properties from hydrogels are also required to mechanically mimic the native soft tissues. Herein, we developed a visible-light cross-linked, single-network, biodegradable hydrogel with high elasticity and flexibility for cell printing, which is different from previous highly elastic hydrogel with double-network and two components. The single network hydrogel using only one stimulus (visible light) to trigger gelation can greatly simplify the cell printing process. The obtained hydrogels possessed high elasticity, and their mechanical properties can be tuned to match various native soft tissues. The hydrogels had good cell compatibility to support fibroblast growth in vitro. Various human cells were bioprinted with the hydrogels to form cell-gel constructs, in which the cells exhibited high viability after 7 days of culture. Complex patterns were printed by the hydrogels, suggesting the hydrogel feasibility for cell printing. We believe that this highly elastic, single network hydrogel can be simply printed with different cell types, and it may provide a new material platform and a new way of thinking for hydrogel-based bioprinting research. PMID- 29451386 TI - Optically Switchable Photocatalysis in Ultrathin Black Phosphorus Nanosheets. AB - Recently low-dimensional materials hold great potential in the field of photocatalysis, whereas the concomitantly promoted many-body effects have long been ignored. Such Coulomb interaction-mediated effects would lead to some intriguing, nontrivial band structures, thus promising versatile photocatalytic performances and optimized strategies. Here, we demonstrate that ultrathin black phosphorus (BP) nanosheets exhibit an exotic, excitation-energy-dependent, optical switching effect in photocatalytic reactive oxygen species (ROS) generation. It is, for the first time, observed that singlet oxygen (1O2) and hydroxyl radical (*OH) are the dominant ROS products under visible- and ultraviolet-light excitations, respectively. Such an effect can be understood as a result of subband structure, where energy-transfer and charge-transfer processes are feasible under excitations in the first and second subband systems, respectively. This work not only establishes an in-depth understanding on the influence of many-body effects on photocatalysis but also paves the way for optimizing catalytic performances via controllable photoexcitation.

AB - In this communication, the AuIn 1:1 phase ( Naturwissenschaften , 1953 , 40 , 437 , DOI: 10.1007/BF00590353 ), and its ordering behavior at various temperatures is investigated. To enable the growth of a X-ray suitable specimen, a tempering routine was established by the interpretation of a differential scanning calorimetry (DSC) study. In this way, good quality single crystals were grown and measured at the Crystal beamline at Synchrotron SOLEIL. From the acquired data, three variations of this structure could be found at temperatures of 400 degrees C and 300 degrees C and room temperature, with differing degrees of incommensurate modulation. Diffuse scattering found at 400 degrees C was interpreted with the help of a three-dimensional difference pair distribution function (3D-DeltaPDF) study.

AB - Staphylococcus aureus is a major bacterial pathogen that invades and damages host tissue by the expression of devastating toxins. We here performed a phenotypic screen of 35 molecules that were structurally inspired by previous hydroxyamide based S. aureus virulence inhibitors compiled from commercial sources or designed and synthesized de novo. One of the most potent compounds, AV73, not only reduced hemolytic alpha-hemolysin production in S. aureus but also impeded in vitro biofilm formation. The effect of AV73 on bacterial proteomes and extracellular protein levels was analyzed by quantitative proteomics and revealed a significant down-regulation of major virulence and biofilm promoting proteins. To elucidate the mode of action of AV73, target identification was performed using affinity based protein profiling (AfBPP), where among others YidC was identified as a target. PMID- 29451389 TI - Molecular Dynamics Study of Hydrophilic Sphalerite (110) Surface as Modified by Normal and Branched Butylthiols. AB - Molecular dynamics simulation was used to study the wettability of the hydrophilic sphalerite (110) surface chemically modified by butylthiols made up of normal and branched alkyl tails, referred to as n-butylthiol and i-butylthiol hereafter, at different adsorption site coverages. Butylthiol molecules were grafted onto the adsorption sites of the surface in two different distributions ordered and random. The results showed that for a given butylthiol at a given site coverage, random surface distribution yielded a slightly larger contact angle. This observation was attributed to the fact that average distances between the first and second nearest neighbors of butylthiol molecules are shorter in the case of random surface distribution, resulting in smaller patches of bare surface exposed to water molecules compared to those of the ordered surface distribution. Regardless of the tail structure, the random surface distribution exhibited hydrophobic character (i.e., contact angle >= 90 degrees ) at a relatively low site coverage of about 25%. The test area method and the Kirkwood and Buff approach were adopted to estimate surface energies (gammaSV) of the bare sphalerite (110) surface and the collector monolayer, respectively. Using the obtained gammaSV values of these two pure states, the apparent surface energy as a function of surface coverage was determined based on Cassie's law. This allowed us to estimate the corresponding values of solid-liquid apparent interfacial tension (gammaSL). Both gammaSV and gammaSL exhibit a linear inverse dependence on surface coverage with a crossover point at 25% site coverage (about 50% surface coverage), above which gammaSV falls below gammaSL, leading to contact angles greater than 90 degrees . The results also revealed that contact angles of the two butylthiols are comparable at site coverages below ~85%, but above that, they are significantly lower for the branched thiols compared to their normal counterparts. Considering the Lennard-Jones interaction energies between the water cluster and the butylthiols, stronger attractive interactions were present in the case of i-butylthiol due to the presence of two methyl groups in its alkyl chain. This difference was the most intense at site coverages above ~85%.

AB - We have prepared COOH- and COOCH3-terminated self-assembled monolayers (SAMs) from undec-10-enoic acid (UDA) and methyl undec-10-enoate (MUDO) molecules on hydrogen-terminated silicon (H-Si) substrates through ultraviolet (UV) irradiation. The as-prepared UDA- and MUDO-SAMs were exposed to 172 nm vacuum-UV (VUV) light in a high vacuum environment (HV, <10-3 Pa) for different periods. The presence of COO components at the surfaces of these SAMs without prior oxidation would simplify the understanding of the origin of the chemical conversions and the changes of surface properties, as the prior oxidation would change the surface properties and generate different oxygenated groups. After the HV-VUV treatment, the abundance of COOH and COOCH3 components of these SAMs decreased without significant dissociation of their C-C backbones. Degradation of these components occurred through dissociating their C-O bonds, resulting in different C?O components. Also, the occurrence of Norrish type pathways resulted in a slight decrease of carbon content and produced CH3 components. We have applied the HV-VUV lithography to control the abundance of COOH and COOCH3 components in well-defined areas and to investigate the friction differences between the irradiated and masked areas. The irradiated areas exhibited lower friction than the masked areas without observing significant height contrasts between these areas. The reduction in friction was attributed to the conversion of the COOH and COOCH3 components to less adhesive components such as C?O and CH3. These experiments suggest the HV-VUV treatments as an approach for low damage dry surface modifications and reductive lithographic techniques at surfaces terminated by acid and ester groups.

AB - AIM: Although regulatory guidances require human metabolism information of drug candidates early in the development process, the human mass balance study (or hADME study), is performed relatively late. hADME studies typically involve the administration of a 14C-radiolabelled drug where biological samples are measured by conventional scintillation counting analysis. Another approach is the administration of therapeutic doses containing a 14C-microtracer followed by accelerator mass spectrometry (AMS) analysis, enabling hADME studies completion much earlier. Consequently, there is an opportunity to change the current drug development paradigm. MATERIALS & METHODS: To evaluate the applicability of the MICADAS-cAMS method, we successfully performed: the validation of MICADAS-cAMS for radioactivity quantification in biomatrices and, a rat ADME study, where the conventional methodology was assessed against a microtracer MICADAS-cAMS approach. RESULTS & DISCUSSION: Combustion AMS (cAMS) technology is applicable to microtracer studies. A favorable opinion from EMA to complete the hADME in a Phase I setting was received, opening the possibilities to change drug development.

AB - RATIONALE: Cleaning tasks may imply exposure to chemical agents with potential harmful effects to the respiratory system, and increased risk of asthma and respiratory symptoms among professional cleaners and in persons cleaning at home has been reported. Long-term consequences of cleaning agents on respiratory health are, however, not well described. OBJECTIVES: This study aimed to investigate long-term effects of occupational cleaning and cleaning at home on lung function decline and airway obstruction. METHODS: The European Community Respiratory Health Survey (ECRHS) investigated a multicenter population-based cohort at three time points over 20 years. A total of 6,235 participants with at least one lung function measurement from 22 study centers, who in ECRHS II responded to questionnaire modules concerning cleaning activities between ECRHS I and ECRHS II, were included. The data were analyzed with mixed linear models adjusting for potential confounders. MEASUREMENTS AND MAIN RESULTS: As compared with women not engaged in cleaning (DeltaFEV1 = -18.5 ml/yr), FEV1 declined more rapidly in women responsible for cleaning at home (-22.1; P = 0.01) and occupational cleaners (-22.4; P = 0.03). The same was found for decline in FVC (DeltaFVC = -8.8 ml/yr; -13.1, P = 0.02; and -15.9, P = 0.002; respectively). Both cleaning sprays and other cleaning agents were associated with accelerated FEV1 decline (-22.0, P = 0.04; and -22.9, P = 0.004; respectively). Cleaning was not significantly associated with lung function decline in men or with FEV1/FVC decline or airway obstruction. CONCLUSIONS: Women cleaning at home or working as occupational cleaners had accelerated decline in lung function, suggesting that exposures related to cleaning activities may constitute a risk to long-term respiratory health.

AB - Conventional sampling techniques for clinical pharmacokinetic studies often require the removal of large blood volumes from patients. This can result in a physiological or emotional burden, particularly for neonates or pediatric patients. Antibiotic pharmacokinetic studies are typically performed on healthy adults or general ward patients. These may not account for alterations to a patient's pathophysiology and can lead to suboptimal treatment. Microsampling offers an important opportunity for clinical pharmacokinetic studies in vulnerable patient populations, where smaller sample volumes can be collected.

AB - The [Formula: see text] Consistency problem takes as input two sets [Formula: see text] and [Formula: see text] of resolved triplets and two sets [Formula: see text] and [Formula: see text] of fan triplets, and asks for a distinctly leaf labeled tree that contains all elements in [Formula: see text] and no elements in [Formula: see text] as embedded subtrees, if such a tree exists. This article presents a detailed characterization of how the computational complexity of the problem changes under various restrictions. Our main result is an efficient algorithm for dense inputs satisfying [Formula: see text] whose running time is linear in the size of the input and therefore optimal. PMID- 29451396 TI - Vacuum assisted breast biopsy (VAB) excision of subcentimeter microcalcifications as an alternative to open biopsy for atypical ductal hyperplasia. AB - OBJECTIVE: Atypical ductal hyperplasia (ADH) is a proliferative lesion associated with a variable increased risk of breast malignancy, but the management of the patients is still not completely defined, with mandatory surgical excision in most cases. To report the results of the conservative management with mammographic checks of patients with ADH diagnosed by vacuum assisted breast biopsy (VAB), without residual calcifications. METHODS: The authors accessed the institutional database of radiological, surgical and pathological anatomy. Inclusion criteria were: ADH diagnosed by VAB on a single group of microcalcifications, without residual post-procedure; follow-up at least of 12 months. Exclusion criteria were the presence of personal history of breast cancer or other high-risk lesions; association with other synchronous lesions, both more and less advanced proliferative lesions. RESULTS: The 65 included patients were all females, with age range of 40-79 years (mean 54 years). The maximum diameter range of the groups of microcalcifications was 4-11 mm (mean 6.2 mm), all classified as BI-RADS 4b (Breast Imaging Reporting and Data System 4b) and defined as fine pleomorphic in 29 cases (45%) or amorphous in 36 cases (55%). The range of follow-up length was 12-156 months (mean 67 months). Only one patients developed new microcalcifications, in the same breast, 48 months after and 15 mm from the first VAB, interpreted as low-grade ductal carcinoma in situ (DCIS) at surgical excision. CONCLUSION: These results could justify the conservative management, in a selected group of patients, being the malignancy rate lower than 2%, considered in the literature as the "probably benign" definition. Advances in knowledge: Increasing the length of follow-up of selected patients conservatively managed can improve the management of ADH cases. PMID- 29451398 TI - Examining heat treatment for stabilization of the lipidome. AB - AIM: To confidently determine lipid-based biomarkers, it is important to minimize variation introduced during preanalytical steps. We evaluated reducing variation associated with lipid measurements in invertebrate sentinel species using a state of-the-art heat treatment technique. MATERIALS AND METHODS: Earthworms (Eisenia fetida), house crickets (Acheta domestica) and ghost shrimp (Palaemonetes paludosus) were euthanized either by flash freezing or heat treatment. For both experiments, samples were either immediately extracted after removal from -80 degrees C storage or incubated on ice for one hour prior to sample weighing and extraction. Lipidomics was performed on resulting extracts using liquid chromatography high resolution tandem mass spectrometry. LipidMatch and LipidSearch were used for lipid identification. RESULTS: Lipid enzymatic products (e.g., phosphatidylmethanols, diglycerides, lysoglycerophospholipids and ether linked/oxidized lysoglycerophospholipids), were in higher concentrations in flash frozen samples, when compared with heat-treated samples. Results suggest that heat treatment reduces phospholipase A and phospholipase D activity. CONCLUSION: Heat treatment reduced enzymatic products and increased precursors of these enzymatic products. We believe heat treatment warrants a closer interrogation for improving the robustness of lipid biomarker research, especially in tissue samples, where enzyme stabilizers are difficult to apply, and for use in field studies, where the stabilization of the collected sample is critical. PMID- 29451399 TI - Assistive technology for communication of older adults: a systematic review. AB - OBJECTIVE: Describe the use of assistive technology to enhance communication opportunities for older adults. METHODS: A systematic review was conducted in two databases, PubMed and Web of Science, by using two different searches in each. The search was limited to original articles, in English language, including people aged 60 years and older that used any type of assistive technology for communication. The articles found in the initial search were filtered by title, abstracts and the remaining articles were fully read. RESULTS: Eighteen studies were included in this review after the reading of full-texts. Most of the studies included apparently healthy participants with communication limitations due to aging related changes and the others included people with some pathology that prevent them from normal communication. CONCLUSION: Four categories of assistive technology were identified: assistive technology for people with speech problems; robot or videoconferencing systems; Information and Communication Technologies and, other types of assistive technology for communication, such as hearing aids and scrapbooks. Assistive technology for communication of older adults is not only used by people with disabilities that prevent them from usual communication. They are mostly for older adults without a pathological communication problem. PMID- 29451400 TI - Designing selective modulators for the nicotinic receptor subtypes: challenges and opportunities. AB - Nicotinic receptors are membrane proteins involved in several physiological processes. They are considered suitable drug targets for various CNS disorders or conditions, as shown by the large number of compounds which have entered clinical trials. In recent years, nonconventional agonists have been discovered: positive allosteric modulators, allosteric agonists, site-specific agonists and silent desensitizers are compounds able to modulate the receptor interacting at sites different from the orthodox one, or to desensitize the receptor without prior opening. While these new findings can further complicate the pharmacology of these proteins and the design and optimization of ligands, they undoubtedly offer new opportunities to find drugs for the many therapeutic indications involving nicotinic receptors.

PMID- 29451402 TI - Editor's Choice - Frailty and the management of patients with acute cardiovascular disease: A position paper from the Acute Cardiovascular Care Association. AB - Frailty is increasingly seen among patients with acute cardiovascular disease. A combination of an ageing population, improved disease survival, treatable long term conditions as well as a greater recognition of the syndrome has accelerated the prevalence of frailty in the modern world. Yet, this has not been matched by an expansion of research. National and international bodies have identified acute cardiovascular disease in the frail as a priority area for care and an entity that requires careful clinical decisions, but there remains a paucity of guidance on treatment efficacy and safety, and how to manage this complex group. This position paper from the Acute Cardiovascular Care Association presents the latest evidence about frailty and the management of frail patients with acute cardiovascular disease, and suggests avenues for future research. PMID- 29451403 TI - Assessment of MRI findings and clinical symptoms in patients with temporomandibular joint disorders. AB - OBJECTIVES: To investigate the correlations among various temporomandibular joint (TMJ) findings on MRI and the relationships between MRI findings and symptoms. METHODS: 425 patients (850 TMJs) with temporomandibular joint disorders (TMDs) who underwent MRI were enrolled. Oblique sagittal proton density-weighted and T2 weighted images in open- and closed-mouth positions were evaluated. MRI findings included disc configuration, disc position, condylar morphology, bone marrow pattern, and joint effusion. Symptoms included TMJ pain, TMJ noise, and limitation of mouth opening. For statistical analyses, Spearman's rank correlation coefficient and logistic regression analysis were applied. RESULTS: Folded disc, disc displacement without reduction (DDWOR), and osteophytes had significant negative correlations with other normal MRI findings (p < 0.01). DDWOR and marrow edema were associated with TMJ pain. Conversely, osteophytes [odds ratio (OR): 0.52; 95% CI (0.30-0.90)] and combination-type condylar degeneration [OR: 0.45; 95% CI (0.24-0.83)] were associated with decreased risk of TMJ pain. Condylar flattening was positively associated with TMJ noise [OR: 5.25; 95% CI (1.44-19.07)] and negatively associated with limitation of mouth opening [OR: 0.34; 95% CI (0.11-0.99)]. High-grade joint effusion was significantly associated with TMJ pain and noise. CONCLUSIONS: DDWOR and high grade joint effusion (an indicator of inflammation in the articular cavity) were associated with TMD symptoms. This finding suggests that treatment strategy for DDWOR and decreasing inflammation might lessen clinical TMD symptoms. Condylar degeneration was not associated with indicators of inflammation or TMJ symptoms. These results suggest that patients with TMD symptoms should undergo initial MRI to allow rapid selection of appropriate therapies. PMID- 29451404 TI - Optimizing NBE PK/PD assays using the Gyrolab Affinity Software; conveniently within the bioanalyst's existing workflow. AB - AIM: The fully automated microfluidics-based Gyrolab is a popular instrument for the bioanalysis of protein therapeutics; requiring minimal sample and reagent volumes. Gyros offers affinity software for determining binding affinity in solution using a high-throughput method and miniaturized reactions. RESULTS: Using this affinity software, multiple CTGF-targeting reagents were characterized on the Gyrolab after <100% target coverage was seen in a cynomolgus pharmacokinetic/PD study dosed with anti-CTGF antibodies. The results uncovered magnitude differences in binding affinities between the dosed antibody, target and assay reagents. CONCLUSION: The binding affinity values were used to investigate reduced target coverage and results highlight potential of the affinity software for incorporation into the bioanalyst's existing Gyrolab workflow for characterizing reagents and optimizing pharmacokinetic/PD bioanalytical assays. PMID- 29451405 TI - Astragalus polysaccharide alleviates LPS-induced inflammation injury by regulating miR-127 in H9c2 cardiomyoblasts. AB - Astragalus polysaccharide (APS) has been widely reported to play an important role in inflammatory response. In this study, we aimed to explore the effects and underlying mechanisms of APS on lipopolysaccharide (LPS)-induced inflammation injury in H9c2 cardiomyoblasts. H9c2 cells were treated with different concentrations of APS, and cell viability was detected by the Cell Counting Kit-8 (CCK-8) assay. Then, the effect of APS on cell viability and apoptosis induced by LPS was determined by CCK-8, flow cytometry, and western blot. The expression and release of inflammatory cytokines were evaluated by quantitative real-time polymerase chain reaction (qRT-PCR), western blot, and enzyme-linked immunosorbent assay (ELISA). Furthermore, expression of miR-127 in H9c2 cells was analyzed by qRT-PCR, and knocked down by transfection with miR-127 inhibitor. Western blot was used to analyze signaling pathway molecules. APS had no effect on H9c2 cells viability. However, APS could alleviate LPS-induced inflammation injury by increasing cell viability, reducing apoptosis, and inhibiting release of inflammatory cytokines in H9c2 cells ( P < 0.05). Additionally, we found that APS increased toll-like receptor 4 (TLR4) expressions in LPS-treated H9c2 cells. Mechanistically, we found that APS exerted the protective effect by down regulating LPS-increased expression of miR-127 ( P < 0.05), inhibiting nuclear factor kappa B (NF-kappaB), JNK and promoting phosphoinositide 3-kinase/protein kinase B (PI3K/AKT) signaling pathways in LPS-treated H9c2 cells. The results demonstrated that APS could protect H9c2 cells against LPS-induced inflammation injury, which might be partially due to miR-127 down-regulation and regulation of NF-kappaB, JNK, and PI3K/AKT signaling pathways. These findings indicated that APS might be a potential therapeutic drug for treatment of myocarditis. PMID- 29451406 TI - Cancer costs and outcomes for common cancer sites in the Finnish population between 2009-2014. AB - BACKGROUND: The cost of cancer and outcomes of cancer care have been discussed a lot since cancer represents 3-6% of total healthcare costs and cost estimations have indicated growing costs. There are studies considering the cost of all cancers, but studies focusing on the cost of disease and outcomes in most common cancer sites are limited. The objective of this study was to analyze the development of the costs and outcomes in Finland between 2009 and 2014 per cancer site. METHODS: The National cost, episode and outcomes data were obtained from the National register databases based on International Statistical Classification of Diseases (ICD)-10 diagnosis codes. Cost data included both the direct and indirect costs. Two hospitals were used to validate the costs of care. The outcome measures included relative survival rate, mortality, sick leave days per patient and number of new disability pensions. FINDINGS: The outcomes of cancer care in most common cancer sites have improved in Finland between 2009-2014. The real costs per new cancer patient decreased in seven out of ten most common cancer sites. The significance of different cost components differ significantly between the different cancer sites. The share of medication costs of the total cost of all cancers increased, but decreased for the five most common cancer sites. INTERPRETATION: The changes in the cost components indicate that the length of stay has shortened in special care and treatment methods have developed towards outpatient care. This partially explains the decrease of costs. Also, at the same time outcomes improved, which indicates that decrease in costs did not come at the expense of treatment quality. As the survival rates increase, the relevance of mortality measures decreases and the relevance of other, patient relevant outcome measures increases. In the future, the outcomes and costs of health care systems should be assessed routinely for the most common patient groups. PMID- 29451407 TI - Advancements in drug development for diarrhea-predominant irritable bowel syndrome. AB - INTRODUCTION: Diarrhea-predominant irritable bowel syndrome (IBS-D) is a common disorder characterized by a complex pathophysiology hampering optimal targeted drug development. Recent advances in our understanding of key underlying mechanisms prompted novel therapeutics including novel pharmacological approaches. Areas covered: This review summarizes the latest advancements in the pipeline of IBS-D drugs focusing on new pharmacological targets, efficacy and safety of medicinal products considering the recent harmonization of regulatory requirements by the FDA and the EMA. Expert opinion: The new 5-HT3 receptor antagonist ramosetron appears a promising therapeutic approach devoid of significant adverse events, although it is presently unavailable in Western countries, most likely because of the precautionary approach taken by regulatory agencies with this drug class. New pharmacological concepts on full agonists/antagonists, mixed-receptor activity and novel drug targets may streamline the present drug pipeline along with the adherence on new regulatory guidelines on outcome measures. Eluxadoline can be taken as an example of this paradigm shift. It has now been granted marketing authorization for IBS-D on both sides of the Atlantic, but it is still considered as a second-line agent by the NICE. There is still much work to be done to fully cover clinical needs of patients with IBS-D. PMID- 29451408 TI - Single Nucleotide Polymorphisms in Key One-Carbon Metabolism Genes and Their Association with Blood Folate and Homocysteine Levels in a Chinese Population in Yunnan. AB - OBJECTIVE: One-carbon metabolism (OCM) is essential for DNA synthesis and methylation. Single nucleotide polymorphisms (SNPs) within OCM genes may affect folic acid (FA) metabolism, disrupt homocysteine (Hcy) homeostasis, and increase the risk of disease. This study investigated the relationship between SNPs in key OCM genes and their association with blood FA and Hcy levels in a healthy population in Yunnan, China. METHODS: Six SNPs within five key OCM genes (MTHFR C677T, MTHFR A1298C, MS A2756G, MTRR A66G, CBS T833C, and SHMT C1420T) were genotyped in 300 healthy volunteers (148 males and 152 females) using polymerase chain reaction/restriction fragment length polymorphism. Blood folate [serum FA (SFA) and red blood cell folate (RBC FA)] and Hcy levels were determined by chemiluminescence immunoassays and enzymatic assays. RESULTS: Subjects with the MTHFR 677TT genotype had significantly higher Hcy levels and RBC FA concentrations compared with those harboring the MTHFR 677CC/CT genotypes (p < 0.01). Both Hcy and blood FA concentrations were also increased in subjects with MS 2756AA, as well as those within CBS 833TT, when compared with those with MS 2756AG/GG (p < 0.05) and CBS 833TC/CC (p < 0.05) genotypes, respectively. Subjects harboring the combined genotype of MTHFR 677TT and MS 2756AA had a higher Hcy concentration than those carrying other MTHFR and MS combinations (p = 0.002). Similarly, subjects harboring the combination of CBS 833TT with MTHFR 677TT had higher Hcy concentrations than those harboring other CBS and MTHFR combinations (p = 0.011). CONCLUSIONS: The genotypes involving the MTHFR C677T, MS A2756G, and CBS T833C polymorphisms, including combinations of these genotypes, were the most important factors associated with blood FA and Hcy levels of the investigated SNPs in the OCM genes. PMID- 29451409 TI - Temporal trends in incidence and outcome of hydatidiform mole: a retrospective cohort study. AB - BACKGROUND: Reported incidence rates of hydatidiform mole (HM) show wide geographic and temporal variations, making reliable international comparisons difficult. The aim of the current study was to examine temporal trends in the incidence of HM and post-molar gestational trophoblastic neoplasia (GTN) in Stockholm County. MATERIAL AND METHODS: Data of all women with a diagnosis of HM in Stockholm County 1991-2010 was collected. The incidence of HM was assessed both in relation to number of births and viable conceptions (births and pregnancy terminations). The risk of post-molar GTN was analysed for all HM, as well as for the subtypes complete (CHM) and partial hydatidiform mole (PHM). Temporal trends were analysed by stratifying the study period into five-year intervals. RESULTS: The overall incidence rate of HM was 2.08/1000 deliveries and 1.48/1000 viable conceptions. A significant temporal increase in the incidence rate of HM, as well as in the total number and proportion of PHM, was seen. Among 956 women with HM, 77 (8%) progressed into post-molar GTN. There was evidence of a slight, but non significant increase in the risk of malignancy in the two last five-year periods under study. CONCLUSIONS: We found evidence of a significant temporal increase in the incidence rate of HM, which could not fully be explained by an increase in maternal age over time. Changes in diagnostic methods probably contributed to the increased incidence rate of PHM. The risk of post-molar GTN remained constant over time. PMID- 29451410 TI - Inclisiran for the treatment of dyslipidemia. AB - INTRODUCTION: Dyslipidemia is one of the most important risk factors for cardiovascular disease. Insufficient reduction in LDL-C from existing therapies in patients at high risk of atherogenic cardiovascular disease is an unmet clinical need. Circulating PCSK9 causes hypercholesterolemia by reducing LDL receptors in hepatocytes. Areas covered: PCSK9 inhibition has emerged as a promising new therapeutic strategy to reduce LDL-C. Inclisiran, a novel, synthetic, siRNA molecule, inhibits PCSK9 synthesis in hepatocytes. Inclisiran targets intracellular PCSK9 synthesis specifically, resulting in a dose dependent, long-term, significant reduction in LDL-C. Inclisiran has been well tolerated and safe, without severe adverse events so far. This review discusses current PCSK9 inhibitors and the results of phase I and II clinical trials of inclisiran. Expert opinion: Plasma PCSK9 enhances the degradation of LDL receptor, resulting in accumulation of LDL-C in the circulation. Current approaches with monoclonal antibodies sequester circulating PCSK9 but require frequent injections. Inclisiran inhibits translation of PCSK9 mRNA and thus switches off PCSK9 production and provides advantages over monoclonal antibodies with an infrequent dosing interval of twice a year to reduce LDL-C by over 50%. Ongoing studies will establish the long-term safety of inclisiran in patients with high cardiovascular risk and an elevated LDL-C. PMID- 29451411 TI - An evaluation of a peer support intervention for student mental health. AB - BACKGROUND: Peer support is support provided by and for people with similar experiences. As students turn to peers for support with their mental health, peer support may provide an opportunity to engage students at an informal level and avoid some barriers to help-seeking. AIMS: The study aimed to identify students likely to attend peer support and evaluate the acceptability and impact of the intervention. METHODS: A six-part peer-led course for mild depression, based on behavioural activation and implementation intentions, was evaluated across eight UK universities with 65 students participating in the evaluation. The evaluation focused on mental wellbeing. RESULTS: Participants were predominately female and had been experiencing anxiety or depression for more than one year. Most participants had already approached professional services for support. At least 57% of participants attended more than one session and 34% completed the course. Students with lower levels of mental wellbeing were more likely to complete the course. For students returning, there was a significant increase in mental wellbeing. CONCLUSIONS: Structured peer support for depression may have benefits in improving student mental wellbeing. However, this is unlikely to have a substantive effect in improving early and preventative intervention. PMID- 29451412 TI - Development and validation of a radiomic signature to predict HPV (p16) status from standard CT imaging: a multicenter study. AB - OBJECTIVES: Human papillomavirus (HPV) positive oropharyngeal cancer (oropharyngeal squamous cell carcinoma, OPSCC) is biologically and clinically different from HPV negative OPSCC. Here, we evaluate the use of a radiomic approach to identify the HPV status of OPSCC. METHODS: Four independent cohorts, totaling 778 OPSCC patients with HPV determined by p16 were collected. We randomly assigned 80% of all data for model training (N = 628) and 20% for validation (N = 150). On the pre-treatment CT images, 902 radiomic features were calculated from the gross tumor volume. Multivariable modeling was performed using least absolute shrinkage and selection operator. To assess the impact of CT artifacts in predicting HPV (p16), a model was developed on all training data (Mall) and on the artifact-free subset of training data (Mno art). Models were validated on all validation data (Vall), and the subgroups with (Vart) and without (Vno art) artifacts. Kaplan-Meier survival analysis was performed to compare HPV status based on p16 and radiomic model predictions. RESULTS: The area under the receiver operator curve for Mall and Mno art ranged between 0.70 and 0.80 and was not significantly different for all validation data sets. There was a consistent and significant split between survival curves with HPV status determined by p16 [p = 0.007; hazard ratio (HR): 0.46], Mall (p = 0.036; HR: 0.55) and Mno art (p = 0.027; HR: 0.49). CONCLUSION: This study provides proof of concept that molecular information can be derived from standard medical images and shows potential for radiomics as imaging biomarker of HPV status. Advances in knowledge: Radiomics has the potential to identify clinically relevant molecular phenotypes. PMID- 29451413 TI - Quantitative analysis of enhanced malignant and benign lesions on contrast enhanced spectral mammography. AB - OBJECTIVE: To retrospectively analyze the quantitative measurement and kinetic enhancement among pathologically proven benign and malignant lesions using contrast-enhanced spectral mammography (CESM). METHODS: We investigated the differences in enhancement between 44 benign and 108 malignant breast lesions in CESM, quantifying the extent of enhancements and the relative enhancements between early (between 2-3 min after contrast medium injection) and late (3-6 min) phases. RESULTS: The enhancement was statistically stronger in malignancies compared to benign lesions, with good performance by the receiver operating characteristic curve [0.877, 95% confidence interval (0.813-0.941)]. Using optimal cut-off value at 220.94 according to Youden index, the sensitivity was 75.9%, specificity 88.6%, positive likelihood ratio 6.681, negative likelihood ratio 0.272 and accuracy 82.3%. The relative enhancement patterns of benign and malignant lesions, showing 29.92 vs 73.08% in the elevated pattern, 7.14 vs 92.86% in the steady pattern, 5.71 vs 94.29% in the depressed pattern, and 80.00 vs 20.00% in non-enhanced lesions (p < 0.0001), respectively. CONCLUSION: Despite variations in the degree of tumour angiogenesis, quantitative analysis of the breast lesions on CESM documented the malignancies had distinctive stronger enhancement and depressed relative enhancement patterns than benign lesions. Advances in knowledge: To our knowledge, this is the first study evaluating the feasibility of quantifying lesion enhancement on CESM. The quantities of enhancement were informative for assessing breast lesions in which the malignancies had stronger enhancement and more relative depressed enhancement than the benign lesions. PMID- 29451414 TI - Comparing methods of misclassification correction for studies of adolescent alcohol use. AB - BACKGROUND: Despite concerns over measurement error, self-report continues to be the most common measure of adolescent alcohol use used by researchers. Objective measures of adolescent alcohol use continue to advance; however, they tend to be cost prohibitive for larger studies. By combining appropriate statistical techniques and validation subsamples, the benefits of objective alcohol measures can be made more accessible to a greater number of researchers. OBJECTIVES: To compare three easily implemented methods to correct for measurement error when objective measures of alcohol use are available for a subsample of participants, regression calibration, multiple imputation for measurement error (MIME), and probabilistic sensitivity analysis (PSA), and provide guidance regarding the use of each method in scenarios likely to occur in practice. METHODS: This simulation experiment compared the performance of each method across different sample sizes, both differential and non-differential error, and differing levels of sensitivity and specificity of the exposure measure. RESULTS: Failure to adjust for measurement error led to substantial bias across all simulated scenarios ranging from a 35% to 208% change in the log-odds. For non-differential misclassification, regression calibration reduced this bias to between a 1% and 23% change in the log-odds regardless of sample size. At higher sample sizes, MIME produced approximately unbiased (between a 0% and 9% change in the log-odds) and relatively efficient corrections for both non-differential and differential misclassification. PSA provided little utility for correcting misclassification due to the inefficiency of its estimates. CONCLUSION: Concern over measurement error resulting from self-reported adolescent alcohol use persists in research. Where appropriate, methods involving validity subsamples provide an efficient avenue for addressing these concerns. PMID- 29451415 TI - Clinical and Economic Impact of an Enhanced Recovery Pathway for Open and Laparoscopic Rectal Surgery. AB - BACKGROUND: The short-term benefits of laparoscopy for rectal surgery are equivocal. The objective of this study was to determine the clinical and economic impact of an enhanced recovery pathway (ERP) for laparoscopic and open rectal surgery. MATERIALS AND METHODS: All patients who underwent elective rectal resection with primary anastomosis between January 2009 and March 2012 at two tertiary-care, university-affiliated institutions were identified. Patients who met inclusion criteria were divided into four groups, according to surgical approach (laparoscopic [lap] or open) and perioperative management (ERP or conventional care [CC]). Length of stay (LOS), postoperative complications, and hospital costs were compared. RESULTS: A total of 381 patients were included in the analysis (201 open-CC, 34 lap-CC, 38 open-ERP, and 108 lap-ERP). Patients were mostly similar at baseline. ERPs significantly reduced median LOS after both open cases (open-CC 10 days versus open-ERP 7.5 days, P = .003) and laparoscopic cases (lap-CC 5 days versus lap-ERP 4.5 days, P = .046). ERPs also reduced variability in LOS compared with CC. There was no difference in postoperative complications with the use of ERPs (open-CC 51% versus open-ERP 50%, P = .419; lap-CC 32% versus lap-ERP 36%, P = .689). On multivariate analysis, both ERP ( 3.6 days [95% confidence interval, CI -6.0 to -1.3]) and laparoscopy (-3.6 days [95% CI -5.9 to -1.0]) were independently associated with decreased LOS. Overall costs were only lower when lap-ERP was compared with open-CC (mean difference 2420 CAN$ [95% CI -5628 to -786]). CONCLUSIONS: ERPs reduced LOS after rectal resections, and the combination of laparoscopy and ERPs significantly reduced overall costs compared to when neither strategy was used. PMID- 29451416 TI - Refinement of in vivo optical imaging: Development of a real-time respiration monitoring system. AB - In vivo optical imaging enables detection and quantification of light-emitting compounds from the whole body in small animals such as the mouse, but it typically requires the use of anaesthetics for subject immobilisation due to long exposure times. Excessively deep anaesthesia can result in unacceptably compromised physiology, whilst excessively light anaesthesia can result in animals waking up. Here we report a respiratory monitoring setup for an in vivo bioluminescence and fluorescence imaging device which simultaneously allows real time adaptive control of anaesthesia depth in multiple animals to (i) potentially increase the consistency between animals, (ii) ensure animals are maintained within minimally intrusive, adequate anaesthetic plane and (iii) provide a valuable refinement strategy for a common challenge within animal-based research. PMID- 29451417 TI - Coumestrol Confers Partial Resistance in Soybean Plants Against Cercospora Leaf Blight. AB - Although previous research showed that the purple symptom of Cercospora leaf blight (CLB) is associated with lower biomass of Cercospora cf. flagellaris and lower concentrations of cercosporin, a reactive oxygen species producer, as compared with blighted leaves, the hypothesis that the purple symptom is a plant reaction to the pathogen has never been tested. In this study, we demonstrated that high levels of coumestrol (COU) were associated with purple symptoms of CLB and that COU has strong antioxidant activity. Additionally, we found that COU is restricted to the pigmented areas of purple leaves, and the pigmentation is restricted to the adaxial surfaces, suggesting that COU may be acting as a sunscreen. Even though COU is associated with the purple leaf symptom, this coumestan is not the direct cause of discoloration in that COU is colorless. Quantification of chlorophyll a and b and total carotenoids suggested that blighted but not purple or asymptomatic leaves were undergoing photooxidative stress. Because the purple symptom is associated with high COU concentrations, lower biomass of C. cf. flagellaris, and lower cercosporin concentrations, we conclude that the purple symptom is a disease resistance reaction, mediated in part by COU, which provides a high level of antioxidant activity and, hence, partial resistance. PMID- 29451418 TI - Patient narratives in Yelp reviews offer insight into opioid experiences and the challenges of pain management. AB - AIM: To characterize Yelp reviews about pain management and opioids. METHODS: We manually coded and applied natural language processing to 836 Yelp reviews of US hospitals mentioning an opioid medication. RESULTS: Yelp reviews by patients and caregivers describing experiences with pain management and opioids had lower ratings compared with other reviews. Negative descriptions of pain management and opioid-related experiences were more commonly described than positive experiences, and the number of themes they reflected was more diverse. CONCLUSION: Yelp reviews offer insights into pain management and opioid use that are not assessed by traditional surveys. As a free, highly utilized source of unstructured narratives, Yelp may allow ongoing assessment of policies related to pain management and opioid use. PMID- 29451419 TI - Physical exercise, nutrition and hormones: three pillars to fight sarcopenia. AB - BACKGROUND: Sarcopenia is a pathophysiological condition diffused in elderly people; it represents a social issue due to the longer life expectancy and the growing aging population. It affects negatively quality of life and it represents a risk factor for other pathologies, such as diabetes, cardiovascular disease, and obesity. No silver bullet exists to hinder sarcopenia, but it may be counteracted by physical exercise, nutrition, and a proper endocrine milieu. Indeed, we aim to analyze the scientific literature to give to clinician effective advices to counteract sarcopenia. Main text: Physical exercise, proper nutrition, optimized hormonal homeostasis represent the three pillars to fight sarcopenia. Physical exercise represents the most effective remedy to face sarcopenia, in particular if it is combined with a proper diet and with an adequate endocrine milieu. Consistency in training, adequate daily protein intake and eugonadism seems to be the keys to fight sarcopenia. The combination of these three pillars might act synergistically. CONCLUSIONS: Optimization of these factors may increase their efficiency; however, scientific data may be sometimes confusing so far. Therefore, we aim to give practical advices to clinician to identify and to highlight the most important aspects in each of these three factors that should be addressed. PMID- 29451420 TI - Integration of clinical pharmacists into an ambulatory, pediatric hematology/oncology/transplant clinic. AB - Objectives To describe key activities performed by a newly deployed clinical pharmacist in an outpatient pediatric hematology, oncology, transplant clinic. To demonstrate how utilization of the pharmacist evolved, as indicated by changes in frequency of key activities, during the first four months of integration. Design Clinical pharmacists were made consistently available in an outpatient clinic serving hematology, oncology, transplant patients and their families. A list of key activities, based on provincial clinical pharmacist standards, was created to provide a framework for the role. Over a four-month period, the pharmacists recorded the number of times activities were performed. Results Over the data collection period, obtaining best possible medication histories (203), providing medication counseling (150), and creating adherence aids (144) were the most commonly performed activities. In comparison to the first month, key activities increased by 73% in the fourth month. Notably, providing recommendations for drug therapy (156%), assessments of adherence (122%), and best possible medication history collection (88%) increased considerably. Conclusions The integration of a pharmacist into an outpatient pediatric hematology, oncology, transplant clinic resulted in the provision of several key clinical pharmacy services. As the role developed, activities were performed more frequently, demonstrating growth in utilization of the pharmacist.

AB - Bone repair bionanocomposite scaffolds were produced by incorporating dense bioactive glass nanoparticles or mesoporous bioactive glass nanospheres into a chitosan-gelatin polymer blend. The in vitro bioactivity of the scaffolds was assessed in simulated body fluid, and cell viability and osteogenic differentiation assays were performed with dental pulp stem cells. Bone regeneration properties of the scaffold materials were in vivo assessed by using a critical-sized femoral defect model in rat. The scaffold nanocomposites showed excellent cytocompatibility and ability to accelerate the crystallization of bone like apatite in vitro. Bionanocomposites prepared with bioactive glass nanoparticles were particularly more active to promote the osteogenic differentiation of dental pulp stem cells as judged by the higher activity of alkaline phosphatase. This result is attributed to the faster dissolution of bioactive glass nanoparticles into osteogenic ionic products compared to mesoporous bioactive glass nanospheres. In vivo experiments demonstrated that bioactive glass nanoparticles (5%)/chitosan-gelatin bionanocomposite significantly produces the highest amount of new bone (~80%) in the defect area after eight weeks of implantation. The bone regeneration capacity exhibited by the scaffolds formulated with nanodimensional bioactive glass particles make them attractive for bone reconstruction applications.

AB - BACKGROUND: Spigelian hernia (SH) is a rare entity, but its surgical treatment is essential because of its high complication risk. Laparoscopic approaches have become the option in elective surgery because it has less morbidity and requires a shorter stay. Several laparoscopic techniques have been employed, but there is no gold standard technique for this kind of hernia. We report, in this study, our experience with intraperitoneal onlay mesh (IPOM) repair. MATERIALS AND METHODS: Fifteen patients underwent elective surgery for SH between 2008 and 2015 in a Short-Stay Surgical Unit. Laparoscopic IPOM technique was performed in all patients. The technique, epidemiological data, operative findings, hospital stay, morbidity, and follow-up are presented. RESULTS: Fifteen patients (8 males) with a median age of 57 years were operated on. They commonly presented an abdominal mass in the flank (73.3%). Computed tomography was necessary in 4 patients to complete preoperative diagnosis. The mean operating time was 43 minutes. No closure of the defect was associated and we employed expanded polytetrafluoroethylene-coated and polyvinylidene fluoride-coated polypropylene meshes. There were no postoperative complications and early discharge was possible in all cases. No recurrences or complications related to the mesh have been detected so far, with a median follow-up of 4 years (1-8). CONCLUSIONS: Our experience shows IPOM laparoscopic SH repair is a safe and effective technique with advantages that allow us to recommend it as the most advisable for SH treatment in Short-Stay Surgical Units. However, current controversies in the use of intraperitoneal meshes must be clarified. PMID- 29451423 TI - Replication of Type 2 diabetes-associated variants in a Saudi Arabian population. AB - Over 120 Type 2 diabetes (T2D) loci have been identified from genome-wide association studies (GWAS), mainly from Caucasian populations. Very limited knowledge is available on the Saudi Arabian population. In this study, 122 previously reported T2D-related variants from 84 loci were examined in a Saudi Arabian cohort of 1,578 individuals (659 T2D cases and 919 controls). Eleven single nucleotide polymorphisms (SNPs) corresponding to nine independent loci had a P value <0.05. If a more stringent Bonferroni threshold of P = 4.1 * 10-4 ( = 0.05/122) were applied, none of the SNPs would have reached the significance level. Nine of the SNPs with a P value <0.05 showed similar odds ratios as previously described, but rs11605924 ( CRY2) and rs9470794 ( ZFAND3) were in the opposite direction. This study demonstrates the importance of large-scale GWAS in the Saudi Arabian population to identify ethnicity-specific disease-associated variants. PMID- 29451424 TI - Risk Factors of Sexual Assault and Victimization Among Youth in Custody. AB - Research suggests that youth are at higher risk of sexual assault and victimization while in custody than adult inmates. However, compared with adult inmates, very little is known about the risk factors associated with such violence among youth in custody. Without sufficient research on risk factors associated with sexual assault and victimization among youth in custody, practitioners and policy makers may be reliant on the adult literature when making decisions about how to address and prevent such violence among juveniles. This article seeks to determine if extrapolating data from the substantial prison literature is appropriate by assessing the parallels between risk factors of sexual assault and victimization among youth in custody and those identified for adult inmates. This study uses data of 8,659 youth from the second administration of the National Survey of Youth in Custody (NSYC-2) to assess correlates of sexual assault and victimization during periods of detention. Study findings show that experiences with assault and victimization prior to the present period of detention were stronger indicators of sexual assault and victimization while in custody than youth characteristics and demographics and other experiences with assault and victimization. Further, there are differences in risk factors associated with sexual assault and victimization among youth in custody compared to adult inmates, which emphasizes the risk of prior sexual assault and victimization in the community and prior custodial settings. PMID- 29451425 TI - Biliary Tract-Infecting Myxosporeans from Estuarine and Reef Stonefish (Scorpaeniformes: Synanceiidae) Off Eastern Australia, with Descriptions of Sphaeromyxa horrida n. sp. and Myxidium lapipiscis n. sp. (Myxosporea: Bivalvulida). AB - Two new species of myxosporeans are described from the gallbladders of estuarine stonefish, Synanceia horrida, and reef stonefish, Synanceia verrucosa, from localities off Cairns, in tropical north Queensland and in Moreton Bay in southern Queensland, Australia. Sphaeromyxa horrida n. sp. can be distinguished from congeners in the morphologically distinct "balbianii" species group within Sphaeromyxa on the basis of morphometric differences in length and width of mature spores, length and width of polar capsules, and unique small-subunit (SSU) ribosomal (rDNA) sequence composition relative to other taxa. Replicate SSU rDNA sequences generated from Sph. horrida n. sp. collected from Sy. horrida and Sy. verrucosa in tropical north Queensland and from Sy. horrida in Moreton Bay were identical, suggesting that this species is widely distributed along the east coast of Australia. Myxidium lapipiscis n. sp. can be distinguished from the majority of described Myxidium species on the basis of its relatively small mature spore size (6.1-7.9 MUm long * 3.1-3.9 MUm wide), and its unique SSU rDNA sequence. Specimens putatively identified as M. lapipiscis n. sp. were found in Sy. horrida from both tropical north Queensland and Moreton Bay, suggesting that this taxon is also widely distributed along the east coast of Australia. However, no molecular data were available for the specimens from tropical north Queensland for comparative genetic analyses. Bayesian inference and maximum likelihood analysis of the SSU rDNA sequences for these 2 new species revealed that Sph. horrida n. sp. formed a strongly supported clade with Sphaeromyxa zaharoni Diamant, Whipps, and Kent, 2004, which was described from the scorpaeniform, Pterois miles, from the Red Sea. This is the first report of myxozoans infecting stonefish (Synanceiidae).

PMID- 29451427 TI - Easier Seen Than Done: Merely Watching Others Perform Can Foster an Illusion of Skill Acquisition. AB - Modern technologies such as YouTube afford unprecedented access to the skilled performances of other people. Six experiments ( N = 2,225) reveal that repeatedly watching others can foster an illusion of skill acquisition. The more people merely watch others perform (without actually practicing themselves), the more they nonetheless believe they could perform the skill, too (Experiment 1). However, people's actual abilities-from throwing darts and doing the moonwalk to playing an online game-do not improve after merely watching others, despite predictions to the contrary (Experiments 2-4). What do viewers see that makes them think they are learning? We found that extensive viewing allows people to track what steps to take (Experiment 5) but not how those steps feel when taking them. Accordingly, experiencing a "taste" of performing attenuates the illusion: Watching others juggle but then holding the pins oneself tempers perceived change in one's own ability (Experiment 6). These findings highlight unforeseen problems for self-assessment when watching other people. PMID- 29451428 TI - Extended-Spectrum beta-Lactamase, AmpC, and MBL-Producing Gram-Negative Bacteria on Fresh Vegetables and Ready-to-Eat Salads Sold in Local Markets. AB - We investigated the occurrence of extended-spectrum beta-lactamase (ESBL), AmpC, and carbapenemase-producing Gram-negative bacteria isolated from 160 samples of fresh vegetables (n = 80) and ready-to-eat (RTE) prepacked salads (n = 80). Phenotypic and genotypic analyses were carried out on the isolates in terms of the species present and relative resistance. Resistance to beta-lactam antibiotics was found in only 44 (24 from fresh vegetables and 20 from RTE salads) of a total of 312 Gram-negative strains (14.1%). The prevalence of ESBL producing strains from fresh vegetables was 83.3% (20/24) and 16.7% (4/24) for AmpC. Among the 20 bacterial isolates from RTE salads, 80% (16/20) were identified as ESBL-producing strains and the remaining 20% (4/20) as MBL producing strains. PCR and sequencing confirmed the presence of blaSHV-12, blaCTX M-1, blaCTX-M-15, blaRHAN-1, blaACC-1, blaDHA-1, blaVIM-1, and blaIMP-1. Seven different replicons were identified, where IncHI1, FIA, and I1 were the most representative types; when compared with the Inc types, isolates from fresh vegetables and RTE salads were similar. The location of genes on a conjugative plasmid was confirmed by positive results obtained with conjugation assays. Our study has demonstrated the occurrence and distribution of ESBL/AmpC and MBL strains in fresh vegetables and RTE salads in Italy and possible public health risks associated with consumption of these fresh products.

PMID- 29451429 TI - Perceived injustice in chronic pain: an examination through the lens of predictive processing. AB - Chronic pain conditions have been shown to be exacerbated by psychological factors, and a better understanding of these factors can inform clinical practice and improve the efficacy of interventions. The current paper investigates perceived injustice, a novel psychosocial construct, within a framework influenced by the tenets of predictive processing. The proposed conceptual model derived from tenets of predictive processing yields a single hierarchical self reconfiguring system driven by prediction, which accounts for a wide range of human experiences such as perception, behavior, learning and emotion. This conceptualization can inform the development and implementation of more targeted therapeutic interventions for chronic pain.

AB - For many years, tuberculosis (TB) has been endemic in Pakistan; many rare and unusual presentations have been reported. There is a myriad of non-specific symptoms which always requires a high index of clinical suspicion for TB. World Health Organization data suggest that Pakistan ranks as the fifth highest country burdened with TB and has the fourth highest prevalence of multi-drug resistant TB globally. With an annual incidence of 277 cases per 100,000, the importance of early diagnosis and treatment is self-evident. We present a case where a strong suspicion of isolated hepatosplenic TB in an immunocompetent patient justified a directed approach. PMID- 29451433 TI - Populations of Phytophthora rubi Show Little Differentiation and High Rates of Migration Among States in the Western United States. AB - Population genetics is a powerful tool to understand patterns and evolutionary processes that are involved in plant-pathogen emergence and adaptation to agricultural ecosystems. We are interested in studying the population dynamics of Phytophthora rubi, the causal agent of Phytophthora root rot in raspberry. P. rubi is found in the western United States, where most of the fresh and processed raspberries are produced. We used genotyping-by-sequencing to characterize genetic diversity in populations of P. rubi sampled in the United States and other countries. Our results confirm that P. rubi is a monophyletic species with complete lineage sorting from its sister taxon P. fragariae. Overall, populations of P. rubi show low genetic diversity across the western United States. Demographic analyses suggest that populations of P. rubi from the western United States are the source of pathogen migration to Europe. We found no evidence for population differentiation at a global or regional (western United States) level. Finally, our results provide evidence of migration from California and Oregon into Washington. This report provides new insights into the evolution and structure of global and western United States populations of the raspberry pathogen P. rubi, indicating that human activity might be involved in moving the pathogen among regions and fields. PMID- 29451434 TI - The ELR-SOBIR1 Complex Functions as a Two-Component Receptor-Like Kinase to Mount Defense Against Phytophthora infestans. AB - The ELICITIN RESPONSE protein (ELR) from Solanum microdontum can recognize INF1 elicitin of Phytophthora infestans and trigger defense responses. ELR is a receptor-like protein (RLP) that lacks a cytoplasmic signaling domain and is anticipated to require interaction with a signaling-competent receptor-like kinase. SUPPRESSOR OF BIR1-1 (SOBIR1) has been proposed as a general interactor for RLPs involved in immunity and, as such, is a potential interactor for ELR. Here, we investigate whether SOBIR1 is required for response to INF1 and resistance to P. infestans and whether it associates with ELR. Our results show that virus-induced gene silencing of SOBIR1 in Nicotiana benthamiana leads to loss of INF1-triggered cell death and increased susceptibility to P. infestans. Using genetic complementation, we found that the kinase activity of SOBIR1 is required for INF1-triggered cell death. Coimmunoprecipitation experiments showed that ELR constitutively associates with potato SOBIR1 in planta, forming a bipartite receptor complex. Upon INF1 elicitation, this ELR-SOBIR1 complex recruits SERK3 (SOMATIC EMBRYOGENESIS RECEPTOR KINASE 3) leading to downstream signaling activation. Overall, our study shows that SOBIR1 is required for basal resistance to P. infestans and for INF1-triggered cell death and functions as an adaptor kinase for ELR. PMID- 29451435 TI - Safe insertion of S-2 alar iliac screws: radiological comparison between 2 insertion points using computed tomography and 3D analysis software. AB - OBJECTIVE S-2 alar iliac (S2AI) screws are commonly used as anchors for lumbosacral fixation. A serious potential complication of screw insertion is major vascular injury due to anterior or caudal screw deviation. To avoid screw deviation, the pelvic inlet view on intraoperative fluoroscopy images is recommended. However, there has been no detailed investigation of optimal fluoroscopic incline with the pelvic inlet view. The purpose of this study was to investigate the safety margins and to optimize fluoroscopic settings to avoid screw deviation with 2 reported insertion techniques using 3D analysis software and CT. METHODS The study included 50 patients (25 men and 25 women) who underwent abdominal-pelvic CT. With the use of software, the ideal S2AI screws were set from 2 entry points: A) the midpoint between the S-1 dorsal foramen and the S-2 dorsal foramen where they meet the lateral sacral crest, and B) 1 mm inferior and 1 mm lateral to the S-1 dorsal foramen. Anteriorly or caudally deviated screws were defined as deviation of a half thread of the ideal screw by rotation anteriorly or caudally from the entry point. The angular safety margins were compared between the 2 entry points, and patients with small safety margins were investigated. Subsequently, fluoroscopic images were virtualized on ray sum rendered images. Conditions that provided proper recognition of screw deviation were investigated via lateral and anteroposterior views with the beam tilted caudally. RESULTS The safety margins of S2AI screws were smaller in the anterior direction than in the caudal direction and by entry point A than by entry point B (A: 9.1 degrees +/- 1.6 degrees and B: 9.7 degrees +/- 1.5 degrees in the anterior direction; A: 10.9 degrees +/- 3.8 degrees and B: 13.9 degrees +/- 4.1 degrees in the caudal direction). In contrast, patients with a deep-seated L 5 vertebral body tended to have smaller safety margins in the caudal direction. All anteriorly deviated screws were recognized with a 60 degrees -70 degrees inlet view from the S-1 slope. The caudally deviated screws were all recognized on the lateral view, but 31% of screws at entry point A and 21% of screws at entry point B were not recognized on the pelvic inlet view. CONCLUSIONS S2AI screws should be carefully placed to avoid anterior deviation compared with caudal deviation in terms of the safety margin, except in patients with a deep seated L-5. The difference in safety margins between entry points A and B was negligible. Intraoperative fluoroscopy is recommended with a pelvic inlet view tilted 60 degrees -70 degrees from the S-1 slope to avoid anterior screw deviation. The lateral view is recommended to confirm that the screw is not deviated caudally. PMID- 29451436 TI - Novel posterior artificial atlanto-odontoid joint for atlantoaxial instability: a biomechanical study. AB - OBJECTIVE Atlantoaxial instability is usually corrected by anterior and/or posterior C1-2 fusion. However, fusion can lead to considerable loss of movement at the C1-2 level, which can adversely impact a patient's quality of life. In this study, the authors investigated the stability and function of a novel posterior artificial atlanto-odontoid joint (NPAAJ) by using cadaveric cervical spines. METHODS The Oc-C7 regions from 10 cadaveric spines were used for anteroposterior (AP) translation and range of motion (ROM) tests while intact and after destabilization, NPAAJ implantation, and double-rod fixation. RESULTS The mean AP C1-2 translational distances in the intact, destabilization, and double rod groups were 6.53 +/- 1.07 mm, 11.54 +/- 1.59 mm, and 3.24 +/- 0.99 mm, respectively, and the AP translational distance in the NPAAJ group was significantly different from that in the intact group (p < 0.05). The AP translational distance in the NPAAJ group was not significantly different from that in the double-rod group (p = 0.24). The mean flexion, extension, and axial rotation ROM values of the NPAAJ group were 9.87 degrees +/- 0.91 degrees , 8.75 degrees +/- 0.99 degrees , and 61.93 degrees +/- 2.93 degrees , respectively, and these were lower than the corresponding values in the intact group (p < 0.05). The mean lateral bending ROM in the NPAAJ group (9.26 degrees +/- 0.86 degrees ) was not significantly different from that in the intact group (p = 0.23), and the flexion, extension, and rotation ranges in the NPAAJ group were 79.5%, 85.2%, and 82.3%, respectively, of those in the intact group. CONCLUSIONS Use of NPAAJ for correction of atlantoaxial instability disorders caused by congenital odontoid dysplasia, odontoid fracture nonunion, and C-1 transverse ligament disruption (IA, IB, and IIB) may restore the stability and preserve most of the ROM of C1-2. Additionally, the NPAAJ may prevent soft tissue from embedding within the joint. However, additional studies should be performed before the NPAAJ is used clinically. PMID- 29451437 TI - Do intraoperative radiographs predict final lumbar sagittal alignment following single-level transforaminal lumbar interbody fusion? AB - OBJECTIVE The study aimed to determine if the intraoperative segmental lordosis (as calculated on a cross-table lateral radiograph following a single-level transforaminal lumbar interbody fusion [TLIF] for degenerative spondylolisthesis/low-grade isthmic spondylolisthesis) is maintained at discharge and at 6 months postsurgery. METHODS The authors reviewed images and medical records of patients >= 16 years of age with a diagnosis of an isolated single level, low-grade spondylolisthesis (degenerative or isthmic) with symptomatic spinal stenosis treated between January 2008 and April 2014. Age, sex, surgical level, surgical approach, and facetectomy (unilateral vs bilateral) were recorded. Upright standardized preoperative, early, and 6-month postoperative radiographs, as well as intraoperative lateral radiographs, were analyzed for the pelvic incidence, segmental lumbar lordosis (SLL) at the TILF level, and total LL (TLL). In addition, the anteroposterior position of the cage in the disc space was documented. Data are presented as the mean +/- SD; a p value < 0.05 was considered significant. RESULTS Eighty-four patients were included in the study. The mean age of patients was 56.8 +/- 13.7 years, and 46 patients (55%) were men. The mean pelvic incidence was 59.7 degrees +/- 11.9 degrees , and a posterior midline approach was used in 47 cases (56%). All TLIF procedures were single level using a bullet-shaped cage. A bilateral facetectomy was performed in 17 patients (20.2%), and 89.3% of procedures were done at the L4-5 and L5-S1 segments. SLL significantly improved intraoperatively from 15.8 degrees +/- 7.5 degrees to 20.9 degrees +/- 7.7 degrees , but the correction was lost after ambulation. Compared with preoperative values, at 6 months the change in SLL was modest at 1.8 degrees +/- 6.7 degrees (p = 0.025), whereas TLL increased by 4.3 degrees +/- 9.6 degrees (p < 0.001). The anteroposterior position of the cage, approach, level of surgery, and use of a bilateral facetectomy did not significantly affect postoperative LL. CONCLUSIONS Following a single-level TLIF procedure using a bullet-shaped cage, the intraoperative improvement in SLL is largely lost after ambulation. The improvement in TLL over time is probably due to the decompression part of the procedure. The approach, level of surgery, bilateral facetectomy, and position of the cage do not seem to have a significant effect on LL achieved postoperatively. PMID- 29451439 TI - Editorial.

AB - OBJECTIVE The purpose of this study was to determine the feasibility of rectum reinnervation with transfer of a primarily genitofemoral nerve to the pelvic nerve in the rat. METHODS Thirty-six male rats were randomly divided into 3 groups: rats in the nerve transfer group (n = 12) were subjected to rectal denervation and then bilateral genitofemoral nerve-pelvic nerve transfer; rats in the nerve resection group (n = 12) underwent rectum denervation without nerve transfer; and rats in the control group (n = 12) underwent sham surgery. Rectum denervation was achieved by transection of the L-6 spinal nerves, the spinal nerves below L-6, and the pelvic nerve. Four months postoperatively, retrograde nerve tracing, regenerative nerve morphological examination, and rectal manometry assessment were performed. RESULTS Regenerative nerve morphological examination showed good axonal regeneration after genitofemoral nerve transfer. Nerve stimulation induced increased rectal pressures in 10 of 12 rats in the nerve transfer group. The mean rectal pressure in this group was 54.9 +/- 7.1 mm Hg, which is higher than the mean value in the nerve resection group (5.5 +/- 2.0 mm Hg) but lower than that in the control group (70.6 +/- 8.5 mm Hg) (p < 0.05). The appearance of FluoroGold-labeled neurons in the L-1 and L-2 spinal cord segments in the nerve transfer group confirmed the formation of new neural pathways. CONCLUSIONS The results have demonstrated that genitofemoral nerve-pelvic nerve transfer can achieve nerve regeneration. In this animal model, the authors were able to reinnervate the rectum by nerve transfer. PMID- 29451441 TI - MSJ 2018-editorial comment.

AB - OBJECTIVES: Cytological assessment of the bone marrow is an essential tool for understanding and investigating haematological abnormalities. Sometimes it represents the only way to reach a definitive diagnosis. The purpose of this study was to provide a general overview regarding the prevalence of feline bone marrow disorders encountered in a private European laboratory setting, to classify them and to assess the differential cell counts related to such disorders. METHODS: In total, 152 bone marrow samples were classified using cytological and numerical criteria. The bone marrow cytological examinations were performed after the identification of haematological alterations, such as cytopenias, increased number of cells or suspicion of malignant blood disorders. RESULTS: Of the 152 bone marrow samples evaluated, 71 (46.7%) were classified as hyperplastic, primarily granulocytic and erythroid hyperplasia (50.7% and 45.1%, respectively, of the total hyperplasia); 23 (15.1%) showed dysmyelopoiesis, mainly in the form of myelodysplastic syndrome (39.1% of the total dysmyelopoiesis); 21 (13.8%) had no cytological abnormalities; 17 (11.2%) were malignant blood disorders; 15 (9.9%) had hypoplastic conditions; and two (1.3%) were miscellaneous diseases. Metastatic disease was detected in only two cases (1.3%). Differential cell counts and myeloid-to-erythroid (M:E) ratios were reported for normal, erythroid hypoplastic, erythroid and granulocytic hyperplastic and dysplastic conditions. CONCLUSIONS AND RELEVANCE: This study provides a general overview of the prevalence and incidence of feline bone marrow disorders together with ranges for differential nucleated cell counts and M:E ratios for the various conditions reported. PMID- 29451444 TI - Survival and prognostic factors in cats with restrictive cardiomyopathy: a review of 90 cases. AB - OBJECTIVES: Large studies focusing on restrictive cardiomyopathy (RCM) in the cat are scarce. The aims of this retrospective study were to describe epidemiological characteristics and to analyse prognostic factors affecting survival in cats with RCM. METHODS: The clinical archives of the Gran Sasso Veterinary Clinic (Milan, Italy) and of the cardiology unit of the Department of Veterinary Medicine (University of Milan, Italy) from 1997-2015 were reviewed for all cats diagnosed with RCM based on an echocardiographic examination (left atrial/biatrial enlargement, normal left ventricle wall thickness, normal or mildly decreased systolic function and restrictive left ventricle filling pattern with pulsed Doppler echocardiography). RESULTS: The study population comprised 90 cats (53 male, 37 female) with an echocardiographic diagnosis of RCM. Most were domestic shorthairs (n = 60) with a mean +/- SD age of 10.0 +/- 4.3 years and a median weight of 3.8 kg (interquartile range 3.2-5 kg). Most cats were symptomatic (n = 87). The most common clinical sign was respiratory distress (n = 75). Follow-up was available for 60 cats and the median survival time (MST) was 69 days (95% confidence interval [CI] 0-175 days). Cardiac-related death occurred in 50 cats. In the multivariate Cox analysis only respiratory distress showed a statistically significant effect on survival. The cats without respiratory distress showed an MST of 466 days (95% CI 0-1208); cats with respiratory distress showing an MST of 64 days (95% CI 8-120; P = 0.011). CONCLUSIONS AND RELEVANCE: RCM can be considered an end-stage condition associated with a poor prognosis, with few cats not showing clinical signs and surviving >1 year. Most cats died of cardiac disease within a very short time. PMID- 29451445 TI - Repeated measurements of renal function in evaluating its decline in cats. AB - OBJECTIVES: The aim of this study was to describe the variability in renal function markers in non-azotaemic and azotaemic cats, and also the rate of change in the markers. METHODS: Plasma creatinine concentration and its reciprocal, glomerular filtration rate (GFR) and urine specific gravity (USG) were studied as markers of renal function in client-owned cats. GFR was determined using a corrected slope-intercept iohexol clearance method. Renal function testing was performed at baseline and a second time point. The within-population variability (coefficient of variation; CV%) was determined at the baseline time point. Within individual variability (CV%) and rate of change over time were determined from the repeated measurements. RESULTS: Twenty-nine cats were included in the study, of which five had azotaemic chronic kidney disease. The within-individual variability (CV%) in creatinine concentration was lower in azotaemic cats than in non-azotaemic cats (6.81% vs 8.82%), whereas the within-individual variability in GFR was higher in azotaemic cats (28.94% vs 19.98%). The within-population variability was greatest for USG (67.86% in azotaemic cats and 38.00% in non azotaemic cats). There was a negative rate of change in creatinine concentration in azotaemic and non-azotaemic cats (-0.0265 and -0.0344 umol/l/day, respectively) and a positive rate of change of GFR in azotaemic and non-azotaemic cats (0.0062 and 0.0028 ml/min/day, respectively). CONCLUSIONS AND RELEVANCE: The within-individual variability data suggest creatinine concentration to be the more useful marker for serial monitoring of renal function in azotaemic cats. In contrast, in non-azotaemic cats, GFR is a more useful marker for serial monitoring of renal function. The majority of cats with azotaemic CKD did not have an appreciable decline in renal function during the study. PMID- 29451446 TI - Improving patient safety during introduction of novel medical devices through cumulative summation analysis. AB - OBJECTIVE The aim of this study was to implement cumulative summation (CUSUM) analysis as an early-warning detection and quality assurance system for preclinical testing of the iSYS1 novel robotic trajectory guidance system. METHODS Anatomically accurate 3D-printed skull phantoms were created for 3 patients who underwent implantation of 21 stereoelectroencephalography electrodes by surgeons using the current standard of care (frameless technique). Implantation schema were recreated using the iSYS1 system, and paired accuracy measures were compared with the previous frameless implantations. Entry point, target point, and implantation angle accuracy were measured on postimplantation CT scans. CUSUM analysis was undertaken prospectively. RESULTS The iSYS1 trajectory guidance system significantly improved electrode entry point accuracies from 1.90 +/- 0.96 mm (mean +/- SD) to 0.76 +/- 0.57 mm (mean +/- SD) without increasing implantation risk. CUSUM analysis was successful as a continuous measure of surgical performance and acted as an early-warning detection system. The surgical learning curve, although minimal, showed improvement after insertion of the eighth electrode. CONCLUSIONS The iSYS1 trajectory guidance system did not show any increased risk during phantom preclinical testing when used by neurosurgeons who had no experience with its use. CUSUM analysis is a simple technique that can be applied to all stages of the IDEAL (idea, development, exploration, assessment) framework as an extra patient safety mechanism. Further clinical trials are required to prove the efficacy of the device.

AB - OBJECTIVE Currently, there is no treatment that slows or halts the progression of Parkinson's disease. Delivery of various neurotrophic factors to restore dopaminergic function has become a focus of study in an effort to fill this unmet need for patients with Parkinson's disease. Schwann cells provide a readily available source of such factors. This study presents a 12-month evaluation of safety and feasibility, as well as the clinical response, of implanting autologous peripheral nerve grafts into the substantia nigra of patients with Parkinson's disease at the time of deep brain stimulation (DBS) surgery. METHODS Standard DBS surgery targeting the subthalamic nucleus was performed in 8 study participants. After DBS lead implantation, a section of the sural nerve containing Schwann cells was harvested and unilaterally grafted to the substantia nigra. Adverse events were continually monitored. Baseline clinical data were obtained during standard preoperative evaluations. Clinical outcome data were obtained with postoperative clinical evaluations, neuropsychological testing, and MRI at 1 year after surgery. RESULTS All 8 participants were implanted with DBS systems and grafts. Adverse event profiles were comparable to those of standard DBS surgery with the exception of 1 superficial infection at the sural nerve harvest site. Three participants also reported numbness in the distribution of the sural nerve distal to the harvest site. Motor scores on Unified Parkinson's Disease Rating Scale (UPDRS) part III while the participant was off therapy at 12 months improved from baseline (mean +/- SD 25.1 +/- 15.9 points at 12 months vs 32.5 +/- 9.7 points at baseline). An analysis of the lateralized UPDRS scores also showed a greater overall reduction in scores on the side contralateral to the graft. CONCLUSIONS Peripheral nerve graft delivery to the substantia nigra at the time of DBS surgery is feasible and safe based on the results of this initial pilot study. Clinical outcome data from this phase I trial suggests that grafting may have some clinical benefit and certainly warrants further study to determine if this is an efficacious and neurorestorative therapy.

AB - OBJECTIVE In this study, the authors used a surgical model of end-to-side neurorrhaphy between a nerve graft and a donor tibial nerve in adult rats to investigate the optimal conditions for axonal regeneration induced by the donor nerve. They also assessed the importance of a more favorable pathway using a predegenerated nerve graft to attract regenerating axons to regrow into the graft and then directing and improving their growth toward the target in comparison with results obtained with a fresh nerve graft. METHODS End-to-side neurorrhaphy was performed between a nerve graft and a donor tibial nerve. The nerve graft was obtained from the left tibial nerve, which was either freshly removed or predegenerated 1 week prior to neurorrhaphy. The donor right tibial nerve was injured by epineurium removal alone, injured by epineurium removal with cross section of 20% or 50% of the total axons at the coaptation site, or left intact. The animals were followed postoperatively for a 6-week period, and outcomes were evaluated by optical microscopy and retrograde labeling to detect the regenerated primary sensory neurons located in the lumbar dorsal root ganglia and spinal motor neurons located in the lumbar spinal ventral horn. RESULTS At the end of the follow-up period, no regenerating axons were observed in the nerve grafts when the donor nerve was left intact, and very few axons were detected when the donor nerve was injured by epineurium removal alone. However, numerous regenerating axons appeared in the grafts when the donor nerve was axotomized, and the greatest number was achieved with a 50% cross section axotomized nerve. In the rats with a 50% cross section of the donor nerve, better nerve-like morphology of the grafts was observed, without connective adhesions. When a predegenerated nerve graft was used, more regenerating axons were attracted and elongated with a more regular shape and improved myelination. CONCLUSIONS Axonal regrowth into a nerve graft depends on axotomy of the donor nerve after end-to side neurorrhaphy. More efficient attraction and an improved structure of the regenerating axons were achieved when a predegenerated nerve graft was used. Furthermore, a nerve graft may require a certain number of regenerating axons to maintain a nerve-like morphology. PMID- 29451449 TI - Letter to the Editor.

PMID- 29451451 TI - Critical assessment of pediatric neurosurgery patient/parent educational information obtained via the Internet. AB - OBJECTIVE The Internet is used frequently by patients and family members to acquire information about pediatric neurosurgical conditions. The sources, nature, accuracy, and usefulness of this information have not been examined recently. The authors analyzed the results from searches of 10 common pediatric neurosurgical terms using a novel scoring test to assess the value of the educational information obtained. METHODS Google and Bing searches were performed for 10 common pediatric neurosurgical topics (concussion, craniosynostosis, hydrocephalus, pediatric brain tumor, pediatric Chiari malformation, pediatric epilepsy surgery, pediatric neurosurgery, plagiocephaly, spina bifida, and tethered spinal cord). The first 10 "hits" obtained with each search engine were analyzed using the Currency, Relevance, Authority, Accuracy, and Purpose (CRAAP) test, which assigns a numerical score in each of 5 domains. Agreement between results was assessed for 1) concurrent searches with Google and Bing; 2) Google searches over time (6 months apart); 3) Google searches using mobile and PC platforms concurrently; and 4) searches using privacy settings. Readability was assessed with an online analytical tool. RESULTS Google and Bing searches yielded information with similar CRAAP scores (mean 72% and 75%, respectively), but with frequently differing results (58% concordance/matching results). There was a high level of agreement (72% concordance) over time for Google searches and also between searches using general and privacy settings (92% concordance). Government sources scored the best in both CRAAP score and readability. Hospitals and universities were the most prevalent sources, but these sources had the lowest CRAAP scores, due in part to an abundance of self-marketing. The CRAAP scores for mobile and desktop platforms did not differ significantly (p = 0.49). CONCLUSIONS Google and Bing searches yielded useful educational information, using either mobile or PC platforms. Most information was relevant and accurate; however, the depth and breadth of information was variable. Search results over a 6-month period were moderately stable. Pediatric neurosurgery practices and neurosurgical professional organization websites were inferior (less current, less accurate, less authoritative, and less purposeful) to governmental and encyclopedia-type resources such as Wikipedia. This presents an opportunity for pediatric neurosurgeons to participate in the creation of better online patient/parent educational material. PMID- 29451452 TI - Epidemiology of spinal injury in childhood and adolescence in the United States: 1997-2012. AB - OBJECTIVE There has been no successful study of trends in population-based incidences of pediatric spinal injury in the United States. The goal of the current study was to develop robust data to correct this deficiency in contemporary trauma epidemiology. METHODS Discharges coded for spinal injury were extracted from the Kids' Inpatient Database for 1997, 2000, 2003, 2006, 2009, and 2012 for patients younger than 18 years. Childhood was defined as ages 0 through 14 years and adolescence as ages 15, 16, and 17 years. Denominator population data were taken from the website of the US Census. Annual incidences were estimated for hospitalization for spinal injury, spinal cord injury (SCI), and hospital death with spinal injury. Mechanistic and anatomical patterns of injury were studied. RESULTS The annual population-based incidences of hospitalization for spinal injury, SCI, and death with spinal injury trended downward from 1997 to 2012 for children and adolescents in the United States. Rates of SCI and death fell faster than overall hospitalization rates, suggesting lower thresholds for admission or greater diagnostic sensitivity to minor injuries over time. The incidence of hospitalization for spinal injury was roughly 8 times greater for adolescents than for children, and the incidence of SCI was roughly 6 times greater. Motor vehicle crash predominated among mechanisms for both children and adolescents, but penetrating injuries and sport injuries were more commonly associated with SCI. Lumbosacral injuries predominated in both children and adolescents, but injuries of the cervical spine were more commonly associated with SCI. CONCLUSIONS Further research is needed to identify the cause or causes of the observed decline in injury rates. Epidemiological data can inform and support prevention efforts. PMID- 29451453 TI - Trapped ventricle after laser ablation of a subependymal giant cell astrocytoma complicated by intraventricular gadolinium extravasation: case report. AB - Magnetic resonance imaging-guided stereotactic laser ablation of intracranial targets, including brain tumors, has expanded dramatically over the past decade, but there have been few reports of complications, especially those occurring in a delayed fashion. Laser ablation of subependymal giant cell astrocytomas (SEGAs) is an attractive alternative to maintenance immunotherapy in some children with tuberous sclerosis complex (TSC); however, the effect of treatment on disease progression and the nature and frequency of potential complications remains largely unknown. The authors report the case of a 5-year-old boy with TSC who underwent stereotactic laser ablation of a SEGA at the right foramen of Monro on 2 separate occasions. After the second ablation, immediate posttreatment MRI revealed gadolinium extravasation from the tumor into the lateral ventricle. Nine months later, the patient presented with papilledema and delayed obstructive hydrocephalus secondary to intraventricular adhesions causing a trapped right lateral ventricle. This was successfully treated with endoscopic septostomy. The authors discuss the potential cause and clinical management of a delayed complication not previously reported after a relatively novel surgical therapy. PMID- 29451454 TI - Efficacy of intraoperative ultrasonography in neurosurgical tumor resection. AB - OBJECTIVE Intraoperative ultrasonography (IOUS) is a widely accessible imaging modality that provides real-time surgical guidance with minimal identified risk or additional operative time. A recent study by the authors found a strong correlation between IOUS and postoperative MRI findings when evaluating the extent of tumor resection, suggesting that IOUS might have significant clinical implications. The objective of this study was to expand on results from the previous study in order to provide more evidence on the usage of IOUS in the determination of gross-total resection (GTR) in both adult and pediatric patients with brain tumors. METHODS This study consisted of a retrospective review of adult and pediatric neurosurgical patients who were treated at Albany Medical Center between August 2009 and March 2016 for a tumor of the brain. All patients were treated with IOUS and then underwent postoperative MRI (with and without contrast) within 1 week of surgery. RESULTS A total of 260 patients (55% of whom were males) met inclusion criteria for the study (age range 3 months to 84 years). IOUS results showed a strong association with postoperative MRI results (phi = 0.693, p < 0.001) and an 81% intended GTR rate. In cases in which GTR was pursued, 19% had false-negative results. IOUS was able to accurately identify residual tumor in 100% of subtotal resection cases where resection was stopped due to invasion of tumor into eloquent locations. Cases involving gliomas had a 75% intended GTR rate and a 25% false-negative rate. Cases involving metastatic tumors had an 87% intended GTR rate and a 13% false-negative rate. The sensitivity, specificity, negative predictive value, and positive predictive value are reported for IOUS in all included tumor pathologies, glioma cases, and metastatic tumor cases, respectively. CONCLUSIONS The use of IOUS may allow for a reliable imaging modality to achieve a more successful GTR of brain tumors in both adult and pediatric neurosurgical patients. When attempting GTR, the authors demonstrated an 81% GTR rate. The authors also report false-negative IOUS results in 19% of attempted GTR cases. The authors support the use of IOUS in both adult and pediatric CNS tumor surgery to improve surgical outcomes. However, further studies are warranted to address existing limitations with its use to further improve its efficacy and better define its role as an intraoperative imaging tool. PMID- 29451455 TI - Laser ablative therapy of sessile hypothalamic hamartomas in children using interventional MRI: report of 5 cases. AB - Hypothalamic hamartomas (HHs) are benign lesions that cause medically refractory seizures, behavioral disturbances, and endocrine dysfunction. Open resection of HHs does not guarantee seizure freedom and carries a relatively high risk of morbidity. Minimally invasive stereotactic laser ablation has recently been described as an effective and safe alternative for HH treatment. Prior studies have not, however, assessed HH lesion size and morphology, 2 factors that may influence treatment results and, ultimately, the generalizability of their findings. In this paper, the authors describe seizure outcomes for 5 pediatric patients who underwent laser ablation of sessile HHs. Lesions were treated using a frameless, interventional MRI-guided approach, which facilitated laser targeting to specific components of these complex lesions. The authors' experiences in these cases substantiate prior work demonstrating the effectiveness of laser therapy for HHs, while elucidating HH complexity as a potentially important factor in laser treatment planning, and in the interpretation of early studies describing this treatment method.

PMID- 29451456 TI - Clival meningocele causing bilateral hearing loss in a child due to superficial siderosis of the central nervous system: case report. AB - Superficial siderosis (SS) of the CNS is a rare and often unrecognized condition. Caused by hemosiderin deposition from chronic, repetitive hemorrhage in the subarachnoid space, it results in parenchymal damage in the subpial layers of the brain and spinal cord. T2-weighted MRI shows the characteristic hypointensity of hemosiderin deposition, classically occurring around the cerebellum, brainstem, and spinal cord. Patients present with progressive gait ataxia and sensorineural hearing impairment. Although there have been several studies, case reports, and review articles over the years, the clear pathophysiology of subarachnoid space hemorrhage remains to be elucidated. The proposed causes include prior intradural surgery, prior trauma, tumors, vascular abnormalities, nerve root avulsion, and dural abnormalities. Surgical repair of a dural defect associated with SS has been shown to be efficacious at preventing symptomatic progression. There have been several reports of dural defects within the spinal canal treated with surgery. Here, the authors present the first known case of a dural defect of the ventral skull base, namely a clival meningocele, presumed to be causing SS. In this case report, a 10-year-old girl with a history of head trauma at the age of 3 years was found to have a clival meningocele 3 years after her original trauma. On follow-up imaging, the patient was found to have radiographic growth of the meningocele along with evidence of SS of the CNS. The patient was treated conservatively until she began to have progressive hearing loss. It was presumed that the growing meningocele was the source of her SS. An endoscopic endonasal transclival approach with a multilayer dural reconstruction was performed to fix the dural defect and repair the meningocele in hopes of mitigating the progression of her symptoms. At her 12-month postoperative follow-up, she was doing well, with audiometry showing a slightly decreased hearing threshold in the left ear but improved speech discrimination bilaterally. Postoperative MRI showed a stable level of hemosiderin deposition and meningocele repair. Long-term follow up will be necessary to evaluate for continued clinical stabilization or possible improvement. PMID- 29451458 TI - Immigrant mothers' preferences for children's sexes: A register-based study of fertility behaviour in Norway. AB - Parental sex preferences have been documented in many native populations, but much less evidence is available on immigrants' preferences for the sexes of their children. Using high-quality longitudinal register data from Norway, a country with a recent immigration history, we estimate hazards regression models of third birth risks by the sex composition of the first two children. A central question in the extant literature is whether the sex preferences of immigrant mothers match those observed in their country of origin, or if cultural adaption to local conditions is more important. Our analyses indicate that the sex preferences of immigrants generally match those previously documented for their native population, especially in the case of son preferences. The pattern of sex preferences is unmodified by the mother's exposure to the host society. In sum, our evidence generally supports theories emphasizing cultural persistence in preferences, rather than theories of adaption or immigrant selectivity. PMID- 29451460 TI - Early-Childhood Conduct Problems Predict Economic and Political Discontent in Adulthood: Evidence From Two Large, Longitudinal UK Cohorts. AB - Longstanding interest has been directed toward the etiology of sociopolitical attitudes. Personality traits have been posited as antecedents; however, most work addressing such links has been limited to cross-sectional study designs. The current study used data from two large (both Ns > 8,700), longitudinal cohorts of individuals from the United Kingdom who were parent-assessed on a measure of temperament (assessing anxiety, conduct problems, and hyperactivity) at age 5 or 7 years and on a range of sociopolitical attitudes at age 30 or 33 years. In both cohorts, higher levels of childhood conduct problems predicted higher levels of economic and political discontent in adulthood. These associations were still evident when controlling for sex, childhood intelligence, and parental social class. In both cohorts, this pathway was partially mediated by educational attainment and achieved social class. These findings are consistent with the perspective that early-life temperament gives rise to adult political sentiment. PMID- 29451459 TI - Apiaceous Vegetables and Cruciferous Phytochemicals Reduced PhIP-DNA Adducts in Prostate but Not in Pancreas of Wistar Rats. AB - We previously showed rats fed with apiaceous vegetables, but not with their putative chemopreventive phytochemicals, reduced colonic DNA adducts formed by 2 amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP), a dietary procarcinogen. We report here the effects of feeding apiaceous and cruciferous vegetables versus their purified predominant phytochemicals, either alone or combined, on prostate and pancreatic PhIP-DNA adduct formation. In experiment I, male Wistar rats received three supplemented diets: CRU (cruciferous vegetables), API (apiaceous vegetables), and CRU+API (both types of vegetables). In experiment II, rats received three diets supplemented with phytochemicals matched to their levels in the vegetables from experiment I: P + I (phenethyl isothiocyanate and indole-3 carbinol), FC (furanocoumarins; 5-methoxypsoralen, 8-methoxypsoralen, and isopimpinellin), and COMBO (P + I and FC combined). After 6 days of feeding, PhIP was injected (10 mg/kg body weight) and animals were killed on day 7. PhIP-DNA adducts were analyzed by LC-MS/MS. In prostate, PhIP-DNA adducts were reduced by API (33%, P < .05), P + I (45%, P < .001), and COMBO (30%, P < .01). There were no effects observed in pancreas. Our results suggest that fresh vegetables and purified phytochemicals lower PhIP-DNA adducts and may influence cancer risk.

PMID- 29451469 TI - Evaluation of the warming sensation, acceptability, and local tolerability of an acetylcysteine oral solution containing the flavoring agent IFF flavor 316282 in the treatment of productive cough?. AB - OBJECTIVE: This open-label study sought to evaluate the warming sensation produced by IFF flavor 316282 in an acetylcysteine oral solution in subjects with productive cough. MATERIALS: 2% ace-tylcysteine oral solution (200 mg per 10 mL) containing IFF flavor 316282. METHODS: Subjects (N = 57; mean age 38.7 years; 58% female) with a productive cough lasting < 7 days and rated as mild to moderate in severity received 10 mL of study product. Warming sensation intensity was assessed using a 100-mm visual analog scale, its onset and duration using stopwatches, its acceptability using a 9-point scale (from "dislike extremely" to "like extremely") and the taste, texture, and overall acceptability of the solution using 5-point scales (from "unacceptable" to "excellent"). RESULTS: 53 (93.0%) subjects perceived a warming sensation within 10 minutes of swallowing the solution; median onset was ~ 14 seconds, and median duration was ~ 2.8 minutes. Warming sensation intensity increased from baseline by a mean of 29.2 mm when evaluated 60 seconds after ingestion. 30 subjects (52.6%) thought the warming sensation was "just about right"; 25 (43.9%) considered it "too weak" or "much too weak." Most subjects had positive overall ratings ("fair," "good," or "excellent") of the taste (79.0%), texture (96.5%), and solution (91.2%). No treatment-emergent adverse events were reported, and no evidence of oral mucosal irritation was found. CONCLUSION: The addition of IFF flavor 316282 to a 2% acetylcysteine oral solution produced a warming sensation with rapid onset and relatively short duration, which the majority of subjects found acceptable.?. PMID- 29451470 TI - Use of integrated clinical trial protocols - A survey in early medicines development?. AB - PURPOSE: To collect information on the use of integrated protocols in early clinical medicines development. MATERIALS AND METHODS: The questionnaire was mailed in fall 2014 to members of human pharmacology societies in Europe for anonymous responses via the online tool SurveyMonkey(r). RESULTS: 97 respondents reported on 164 integrated protocols overall. In general, integrated protocols comprised 2 or 3 trial elements. One third of integrated protocols involved patients. The most frequent trial elements were single dose, multiple dose, and food effect. Drug-drug interaction, age, gender, and relative/absolute bioavailability were less common elements. Ethnic bridging and mass balance were mentioned in single cases. Out of the entire spectrum of reported trial element combinations, single (ascending) dose plus multiple (ascending) dose was most frequent (90/164 protocols, 55%); 84% of integrated protocols used adaptive elements. 29%, 17%, and 8% of integrated protocols required 1, 2, or 3 substantial amendments, respectively. Based on 118 protocols, competent authority approval was granted to 100, deficiency letters were issued 15 times and approval was refused in 3 cases. CONCLUSION: The use of integrated protocols is common practice in early medicines development. Most often single ascending dose and multiple ascending dose were the trial elements combined in one integrated protocol. Perceived main advantages were gain in time and reduced costs. Perceived main disadvantage was increased complexity.?.

PMID- 29451472 TI - Hepcidin and proinflammatory markers in children with chronic kidney disease: A case-control study?. AB - BACKGROUND: Hepcidin is the main regulator of hepcidin-ferroportin axis and is elevated in children with chronic kidney disease (CKD). Anemia of CKD and its relation to hepcidin, interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF alpha), and high-sensitivity C-reactive protein (hs-CRP) in iron- and erythropoietin (EPO)-naive, non-dialyzed children with CKD is under-studied. MATERIALS AND METHODS: This case-control study aimed to study the levels of hepcidin and other proinflammatory markers (IL-6, TNF-alpha, hs-CRP) and their relation with anemia in iron- and erythropoietin-naive, non-dialysis CKD (stage 3 - 5) patients. 32 pediatric CKD stage 3 - 5 patients aged 2 - 18 years without previous iron or EPO therapy were compared with 32 gender- and age-matched healthy controls. The CKD cases were also divided into three categories based on their serum ferritin levels and transferrin saturation (%TSAT): true iron deficiency, impaired iron trafficking, and no iron deficiency. The baseline iron status was then correlated with the serum hepcidin levels. RESULTS: Serum hepcidin, IL-6, and TNF-alpha levels were significantly elevated compared to controls. As CKD stage progressed, hemoglobin levels decreased, while serum hepcidin, IL6, TNF-alpha and hs-CRP levels increased significantly. Serum hepcidin levels correlated positively with IL-6 (r = 0.57, p = 0.001), TNF-alpha (r = 0.34, p = 0.05), hs-CRP (r = 0.36, p = 0.03), and ferritin (r = 0.07, p = 0.001), while being inversely correlated with Total iron binding capacity (TIBC) (r = -0.50, p = 0.003), hemoglobin (r = -0.52, p = 0.001), and glomerular filtration rate (GFR) (r = -0.71, p = 0.000). Serum hepcidin levels were highest in those with impaired iron trafficking, followed by those with no iron deficiency, followed by those with absolute iron deficiency (55.16 vs. 49 vs. 11.8, p = 0.005). Amongst those with no iron deficiency, hepcidin correlated negatively with hemoglobin (r = -0.752, p-value = 0.007). CONCLUSION: A positive correlation between hepcidin and other inflammatory biomarkers in non-dialyzed, iron- and EPO-naive pediatric CKD patients suggests a role of these markers in higher hepcidin production and its contribution to iron-restricted erythropoiesis across the spectrum of CKD. Median hepcidin levels were highest in those with impaired iron trafficking, followed by those with no iron deficiency, followed by those with absolute iron deficiency, suggesting that in an iron-replete state, high hepcidin levels inhibit iron absorption from the gut and release from iron storing cells, thus restricting erythropoiesis leading to anemia.?. PMID- 29451473 TI - Uremia: A historical reappraisal of what happened?. AB - Urea was identified as a urinary salt in 1662 and was the first organic bodily product to be synthesized in vitro in 1828. This heralded the end of an era that defined disease as an imbalance between vital life forces, and catalyzed the merging of organic chemical sciences into clinical medicine. The term uree (urea) was introduced in 1803, its accumulation in blood was dubbed uremie (uremia) in 1847, and the procedure for its removal from urine across semi-permeable membranes designated dialysis in 1861. The advent of modern dialysis in the 20th century provided lifesaving replacement therapy for the universally fatal disease that progressive uremia had been theretofore. Today, the clearance of urea is no longer used as a marker to identify patients with kidney disease; rather it has been adopted as a measure of the adequacy of dialysis, and the "urea toxicity" of yesteryears has been replaced by that of dialyzable "uremic toxins". As a result, the use of the term uremia has become non-uniform and is now applied to variable scenarios ranging from "azotemia" to "kidney failure" and to the symptoms persisting in patients receiving maintenance hemodialysis. In the process, the quest for variably dialyzed uremic toxins has overshadowed the consideration that dialysis is an invasive non-physiologic process that operates counter to normal homeostasis and itself may be toxic.?.

AB - In recent years, the discovery of small non-coding RNAs has opened an all new field in molecular biology. Indeed, these non-coding sequences give rise to powerful regulators of gene expression. Nowadays, different types of small non coding RNAs have been described. Of these, the best-characterized types are microRNAs, piRNAs (Piwi-interacting RNAs) and siRNAs (small interfering RNAs). Because of their fine-tuning important function in the regulation of gene and genome expression, an aberrant expression level of those small non-coding RNAs are associated to several pathologies. While this new research field is attracting attention, many aspects to be discovered. This review focuses on the biogenesis pathways of microRNAs, piRNAs and siRNAs in animals. PMID- 29451485 TI - [The roles of mast cells in radiation-induced damage are still an enigma]. AB - Mast cells are immune cells that mature within the host tissue. The acquired phenotype is dictated by the tissue microenvironment, giving rise to diverse tissue-dependent phenotypes and functions. The lack of cellular models reflecting phenotypes found in vivo and important differences between human and rodent mast cells are obstacles to the understanding of their exact role in several pathophysiological processes. Studies published over the past few years showed that mast cells' role lies far beyond their involvement in allergy and anaphylaxis. Studies demonstrating their participation in innate immune responses as well as tissue scaring and vascular pathologies allowed the understanding of their role in several diseases, but also gave contradictory results, especially concerning tissue response to ionizing radiations. Nevertheless, therapeutic tools exist to target mast cells, such as degranulation inhibitors, antihistamine, protease inhibitors or tyrosine kinase receptors antagonists, and may offer some interesting new therapeutic perspectives to manage acute and chronic after-effects of radiation therapy.

AB - Uveal melanoma is a rare cancer in adults, whose highly stereotyped oncogenic events have been decrypted over the last decade. Its epidemiological, genetic and transcriptional features make it a remarkable model of oncogenesis. Malignant transformation involves almost mutually exclusive alteration of fundamental biologic pathways, including chromatin regulation with inactivation of BAP1, splicing with mutations of SF3B1 or translation with mutations of EIF1AX. Uveal melanoma analyses unraveled the splicing defect due to SF3B1 mutations. Understanding the link between these alterations and malignant transformation will be a key step to define novel therapeutic targets.

AB - After years of development, the use of nanopore as a sensor to sequence DNA molecules is now a viable and promising possibility. Single base pair detection during DNA transport enables to record ultra-long threads with high parallelization and rates. I will present in this review the current methodologies based on electrical detection and biological nanopores and the new methods based on solid state nanopores and optical detection.

AB - After the atomic bombing of Hiroshima and Nagasaki, long-term epidemiological studies were undertaken on the irradiated survivors and their offspring, and are still underway. These thorough studies involving tens of thousands of persons and published in hundreds of papers have shown a moderate increase in cancer incidence for irradiated survivors, with limited impact on their life span (loss of one year at most). In studies on the offspring of these survivors, no statistically significant deleterious effect on malformation frequency, incidence of mutations or mortality from cancer and other diseases has been seen so far. These data are actually the basis for current radiation safety levels; they show that health risks from radiation are limited, but they are not applicable to complex situations such as nuclear power station accidents that involve diverse types of radiation as well as contamination by radioactive materials. PMID- 29451490 TI - [Alternative bases and synthetic life]. AB - Alternative bases that can fit into the DNA double helix have now been used in vivo to direct the synthesis of proteins incorporating unnatural amino acids. This bioengineering feat is significant at both the conceptual and the practical levels. PMID- 29451491 TI - The relationship between spatial configuration and functional connectivity of brain regions. AB - Brain connectivity is often considered in terms of the communication between functionally distinct brain regions. Many studies have investigated the extent to which patterns of coupling strength between multiple neural populations relates to behaviour. For example, studies have used 'functional connectivity fingerprints' to characterise individuals' brain activity. Here, we investigate the extent to which the exact spatial arrangement of cortical regions interacts with measures of brain connectivity. We find that the shape and exact location of brain regions interact strongly with the modelling of brain connectivity, and present evidence that the spatial arrangement of functional regions is strongly predictive of non-imaging measures of behaviour and lifestyle. We believe that, in many cases, cross-subject variations in the spatial configuration of functional brain regions are being interpreted as changes in functional connectivity. Therefore, a better understanding of these effects is important when interpreting the relationship between functional imaging data and cognitive traits. PMID- 29451492 TI - Extreme heterogeneity of influenza virus infection in single cells. AB - Viral infection can dramatically alter a cell's transcriptome. However, these changes have mostly been studied by bulk measurements on many cells. Here we use single-cell mRNA sequencing to examine the transcriptional consequences of influenza virus infection. We find extremely wide cell-to-cell variation in the productivity of viral transcription - viral transcripts comprise less than a percent of total mRNA in many infected cells, but a few cells derive over half their mRNA from virus. Some infected cells fail to express at least one viral gene, but this gene absence only partially explains variation in viral transcriptional load. Despite variation in viral load, the relative abundances of viral mRNAs are fairly consistent across infected cells. Activation of innate immune pathways is rare, but some cellular genes co-vary in abundance with the amount of viral mRNA. Overall, our results highlight the complexity of viral infection at the level of single cells. PMID- 29451495 TI - Perceptually Aware Image Retargeting for Mobile Devices. AB - Retargeting aims at adapting an original high-resolution photograph/video to a low-resolution screen with an arbitrary aspect ratio. Conventional approaches are generally based on desktop PCs, since the computation might be intolerable for mobile platforms (especially when retargeting videos). Typically, only low-level visual features are exploited, and human visual perception is not well encoded. In this paper, we propose a novel retargeting framework that rapidly shrinks a photograph/video by leveraging human gaze behavior. Specifically, we first derive a geometry-preserving graph ranking algorithm, which efficiently selects a few salient object patches to mimic the human gaze shifting path (GSP) when viewing a scene. Afterward, an aggregation-based CNN is developed to hierarchically learn the deep representation for each GSP. Based on this, a probabilistic model is developed to learn the priors of the training photographs that are marked as aesthetically pleasing by professional photographers. We utilize the learned priors to efficiently shrink the corresponding GSP of a retargeted photograph/video to maximize its similarity to those from the training photographs. Extensive experiments have demonstrated that: 1) our method requires less than 35 ms to retarget a photograph (or a video frame) on popular iOS/Android devices, which is orders of magnitude faster than the conventional retargeting algorithms; 2) the retargeted photographs/videos produced by our method significantly outperform those of its competitors based on a paired comparison-based user study; and 3) the learned GSPs are highly indicative of human visual attention according to the human eye tracking experiments. PMID- 29451493 TI - ERalpha promotes murine hematopoietic regeneration through the Ire1alpha-mediated unfolded protein response. AB - Activation of the unfolded protein response (UPR) sustains protein homeostasis (proteostasis) and plays a fundamental role in tissue maintenance and longevity of organisms. Long-range control of UPR activation has been demonstrated in invertebrates, but such mechanisms in mammals remain elusive. Here, we show that the female sex hormone estrogen regulates the UPR in hematopoietic stem cells (HSCs). Estrogen treatment increases the capacity of HSCs to regenerate the hematopoietic system upon transplantation and accelerates regeneration after irradiation. We found that estrogen signals through estrogen receptor alpha (ERalpha) expressed in hematopoietic cells to activate the protective Ire1alpha Xbp1 branch of the UPR. Further, ERalpha-mediated activation of the Ire1alpha Xbp1 pathway confers HSCs with resistance against proteotoxic stress and promotes regeneration. Our findings reveal a systemic mechanism through which HSC function is augmented for hematopoietic regeneration. PMID- 29451494 TI - Single-cell transcriptional dynamics of flavivirus infection. AB - Dengue and Zika viral infections affect millions of people annually and can be complicated by hemorrhage and shock or neurological manifestations, respectively. However, a thorough understanding of the host response to these viruses is lacking, partly because conventional approaches ignore heterogeneity in virus abundance across cells. We present viscRNA-Seq (virus-inclusive single cell RNA Seq), an approach to probe the host transcriptome together with intracellular viral RNA at the single cell level. We applied viscRNA-Seq to monitor dengue and Zika virus infection in cultured cells and discovered extreme heterogeneity in virus abundance. We exploited this variation to identify host factors that show complex dynamics and a high degree of specificity for either virus, including proteins involved in the endoplasmic reticulum translocon, signal peptide processing, and membrane trafficking. We validated the viscRNA-Seq hits and discovered novel proviral and antiviral factors. viscRNA-Seq is a powerful approach to assess the genome-wide virus-host dynamics at single cell level. PMID- 29451496 TI - Significantly enhanced visible light response in single TiO2 nanowire by nitrogen ion implantation. AB - The metal-oxide semiconductor TiO2 shows enormous potential in the field of photoelectric detection; however, UV-light absorption only restricts its widespread application. It is considered that nitrogen doping can improve the visible light absorption of TiO2, but the effect of traditional chemical doping is far from being used for visible light detection. Herein, we dramatically broadened the absorption spectrum of the TiO2 nanowire (NW) by nitrogen ion implantation and apply the N-doped single TiO2 NW to visible light detection for the first time. Moreover, this novel strategy effectively modifies the surface states and thus regulates the height of Schottky barriers at the metal/semiconductor interface, which is crucial to realizing high responsivity and a fast response rate. Under the illumination of a laser with a wavelength of 457 nm, our fabricated photodetector exhibits favorable responsivity (8 A W-1) and a short response time (0.5 s). These results indicate that ion implantation is a promising method in exploring the visible light detection of TiO2. PMID- 29451498 TI - Current fluctuations across a nano-pore. AB - The frequency-dependent spectrum of current fluctuations through nano-scale channels is studied using analytical and computational techniques. Using a stochastic Nernst-Planck description and neglecting the interactions between the ions inside the channel, an expression is derived for the current fluctuations, assuming that the geometry of the channel can be incorporated through the lower limits for various wave-vector modes. Since the resulting expression turns out to be quite complex, a number of further approximations are discussed such that relatively simple expressions can be used for practical purposes. The analytical results are validated using Langevin dynamics simulations. PMID- 29451497 TI - Automated skeletal tissue quantification in the lower leg using peripheral quantitative computed tomography. AB - OBJECTIVE: In this paper we introduce a methodology for hard and soft tissue quantification at proximal, intermediate and distal tibia sites using peripheral quantitative computed tomography scans. Quantification of bone properties is crucial for estimating bone structure resistance to mechanical stress and adaptations to loading. Soft tissue variables can be computed to investigate muscle volume and density, muscle-bone relationship, and fat infiltration. APPROACH: We employed implicit active contour models and clustering techniques for automated segmentation and identification of bone, muscle and fat at [Formula: see text], [Formula: see text], and [Formula: see text] tibia length. Next, we calculated densitometric, area and shape characteristics for each tissue type. We implemented our approach as a multi-platform tool denoted by TIDAQ (tissue identification and quantification) to be used by clinical researchers. MAIN RESULTS: We validated the proposed method against reference quantification measurements and tissue delineations obtained by semi-automated workflows. The average Deming regression slope between the tested and reference method was 1.126 for cross-sectional areas and 1.078 for mineral densities, indicating very good agreement. Our method produced high average coefficient of variation (R 2) estimates: 0.935 for cross-sectional areas and 0.888 for mineral densities over all tibia sites. In addition, our tissue segmentation approach achieved an average Dice coefficient of 0.91 over soft and hard tissues, indicating very good delineation accuracy. SIGNIFICANCE: Our methodology should allow for high throughput, accurate and reproducible automatic quantification of muscle and bone characteristics of the lower leg. This information is critical to evaluate risk of future adverse outcomes and assess the effect of medications, hormones, and behavioral interventions aimed at improving bone and muscle strength. PMID- 29451499 TI - Characterising the frequency response of impedance changes during evoked physiological activity in the rat brain. AB - OBJECTIVE: Electrical impedance tomography (EIT) can image impedance changes associated with evoked physiological activity in the cerebral cortex using an array of epicortical electrodes. An impedance change is observed as the externally applied current, normally confined to the extracellular space is admitted into the conducting intracellular space during neuronal depolarisation. The response is largest at DC and decreases at higher frequencies due to capacitative transfer of current across the membrane. Biophysical modelling has shown that this effect becomes significant above 100 Hz. Recordings at DC, however, are contaminated by physiological endogenous evoked potentials. By moving to 1.7 kHz, images of somatosensory evoked responses have been produced down to 2 mm with a resolution of 2 ms and 200 MUm. Hardware limitations have so far restricted impedance measurements to frequencies <2 kHz. The purpose of this work was to establish the optimal frequency for extending EIT to image throughout the brain and to characterise the response at frequencies >2 kHz using improved hardware. APPROACH: Impedance changes were recorded during forepaw somatosensory stimulation in both cerebral cortex and the VPL nucleus of the thalamus in anaesthetised rats using applied currents of 1 kHz to 10 kHz. MAIN RESULTS: In the cortex, impedance changed by -0.04 +/- 0.02 % at 1 kHz, reached a peak of 0.13 +/- 0.05 % at 1475 Hz and decreased to -0.05 +/- 0.02 % at 10 kHz. At these frequencies, changes in the thalamus were -0.26 +/- 0.1%, -0.4 +/- 0.15 % and 0.08 +/- 0.03 % respectively. The signal-to-noise ratio was also highest at 1475 Hz with values of -29.5 +/- 8 and -31.6 +/-10 recorded from the cortex and thalamus respectively. Signficance: This indicates that the optimal frequency for imaging cortical and thalamic evoked activity using fast neural EIT is 1475 Hz.

AB - The tunable electronic, electrical and optical properties of graphene oxide (GO) sheets were investigated using a controlled reduction by 500 keV Ar+-ion irradiation. The carbon to oxygen ratio of the GO sheets upon the ion beam reduction has been estimated using resonant Rutherford backscattering spectrometry analyses and its effect on the electrical and optical properties of GO sheets has been studied using sheet resistance measurements and photoluminescence (PL) measurements. The restoration of sp 2-hybridized carbon atoms within the sp 3 matrix is found to be increases with increasing the Ar+-ion fluences as evident from Fourier transform infrared, and x-ray absorption near edge structure measurements. The decrease in the number of disorder-induced local density of states (LDOSs) within the pi-pi* gap upon the reduction causes the shifting of PL emission from near infra-red to blue region and decreases the sheet resistance. The improved electrical and optical properties of GO sheets were correlated to the decrease in the number of LDOSs within the pi-pi* gap. Our experimental investigations suggest ion beam irradiation is one of an effective approaches to reduce GO to RGO and to tailor its electronic, electrical and optical properties. PMID- 29451501 TI - Transitions in physiological coupling between heartbeat and pulse across sleep stages. AB - OBJECTIVE: The aim of this study is to investigate the coupling behavior between heartbeat and pulse of blood flow at different sleep stages, and to explore the feasibility of using this coupling strength for automatic sleep staging. APPROACH: The electrocardiogram and photoplethysmography signals are recorded during sleep, and R-wave-to-R-wave intervals (RRI) and pulse-to-pulse intervals (PPI) are extracted respectively. The detrended cross-correlation analysis (DCCA) is applied to quantify long-range cross correlations between the RRIs and PPIs across sleep stages. The DCCA scaling exponents are used as the indicator of coupling strength between heartbeat and pulse, and are compared with detrended fluctuation analysis (DFA) scaling exponents of RRIs and PPIs in the application of sleep stage discrimination. MAIN RESULTS: We find the DCCA scaling exponents between RRIs and PPIs decrease monotonously from wake, REM sleep to light and deep sleep, indicating that the coupling strength between heartbeat and pulse are reduced gradually when entering deep sleep. Statistical analysis shows that the DCCA scaling exponents possess better discrimination ability between wake/REM sleep and light/deep sleep, compared with DFA scaling exponents of RRIs and PPIs. SIGNIFICANCE: Our study reveals the coupling strength between heartbeat and pulse changes regularly across sleep stages, which may help understand the regulation mechanism underlying the cardiovascular system. The DCCA scaling exponents between RRIs and PPIs can be used as an indicator for measuring vigilance level and automatic sleep staging. PMID- 29451503 TI - ? PMID- 29451502 TI - ?

AB - Clinical management of acute pulmonary embolism has changed over the years based on new evidence on diagnosis, prognostic stratification and treatment. The increasing availability of computed tomography angiography has made the diagnosis faster and accurate, although with some concern on radiation exposure and potential for overdiagnosis. The efficacy and safety of simple-to-use oral anticoagulant agents acting as selective direct inhibitors of coagulation certainly offer considerable benefits to the patients. However, the appropriate use of these agents is necessary to maintain an optimal risk-benefit ratio. This paper reports answers to ten frequently asked questions in the management of patients with suspected or proven acute pulmonary embolism. PMID- 29451507 TI - [Appropriateness in Cardiology: a statement of the ANMCO Veneto Region]. AB - Inappropriate tests are responsible for longer waiting lists, higher economical costs for the National Health System and major clinical risks due to radiation exposure from prescription abuse of diagnostic testing. Clinical inappropriateness frequently derives from poor knowledge of guidelines, "defensive medicine" approach and/or repeat requests of patients and family members. About one third of non-invasive imaging tests are considered inappropriate.In order to define the most appropriate instruments for the follow up of the most common cardiovascular diseases with the highest risk of inappropriateness, all the cardiologists of the Veneto Region (Italy), along with the local chapters of the main national cardiology societies and general practitioners have been involved by the Regional Section of the Italian Association of Hospital Cardiologists (ANMCO) in several scientific meetings on the following topics: hypertension, chronic ischemic heart disease, valvular heart disease, heart failure, and atrial fibrillation. This has led to the present document where: (i) the most appropriate clinical and diagnostic strategies are taken into account, and (ii) the most robust scientific evidence is provided for the regulatory commission of the Veneto Region Health Service to identify inappropriateness, prescription unsuitability, and economical sustainability. PMID- 29451508 TI - [Heart failure with mid-range ejection fraction. Looking for Middle Earth?] AB - The latest guidelines of the European Society of Cardiology have proposed a classification of heart failure based on left ventricular ejection fraction. Three distinct groups have been identified: heart failure with ejection fraction >=50%, between 40 and 49%, and <40%. This classification has the advantage to be simple but it has been criticized because it is not clear whether the mid-range ejection fraction group is an independent category or just a transition phase between the other two groups. The purpose of this article is to discuss the characteristics and prognosis of mid-range ejection fraction heart failure on the basis of current evidence. PMID- 29451509 TI - [Diagnosis and treatment of blood volume changes in acute heart failure - a brief practical guide]. AB - The correct management of acute heart failure continues to pose diagnostic and therapeutic challenges. In particular, administering the right type and dose of fluids and drugs, thus avoiding fluid overload while establishing organ perfusion, is of key importance in stabilizing critical patients and improving prognosis. A correct estimate of the fluid volume status, however, may be difficult, as the invasive evaluation of cardiac filling pressures by cardiac catheterization is limited in routine medical practice, and there is no universal consensus on the best tools for its non-invasive evaluation. Here we review current evidence about diagnosis and treatment of fluid volume abnormalities in acute heart failure according to the most recent guidelines.

Preliminary data from a single-center experience on novel oral anticoagulants]. AB - BACKGROUND: Spontaneous reporting system is the most widely used method by pharmacovigilance centers. Its "voluntary nature" represents the main cause of adverse drug reaction (ADR) under-reporting phenomena. The aim of this study was to point out the issue of ADR under-reporting from doctors, particularly serious ADRs and adverse reactions caused by medicinal products subject to additional monitoring, such as novel oral anticoagulants (NOACs). METHODS: Only serious ADRs were analyzed, defined as death, life-threatening ADR, hospitalization (initial or prolonged), disability (significant or permanent), congenital anomaly. Firstly, we analyzed suspected adverse reaction alerts to NOACs submitted to the Area Vasta 2 (ASUR Marche) pharmacovigilance center, from June 16, 2013 to January 14, 2017. Then, we examined alerts coming from all over Italy and from the Marche Region in the same time period. Secondly, the analysis was focused on the Senigallia hospital (where we had an easy access to the medical records archive); patients who experienced an ADR in that time period were identified retrospectively and an alert was submitted. Thirdly, from January 15, 2017 to March 15, 2017, suspected ADR alerts were submitted prospectively. RESULTS: Phase 1: in 43 months, 1625 alerts were submitted from all over Italy, 18 from the Marche Region (one of them from the Senigallia hospital). Phase 2: 8 suspected serious ADRs were collected retrospectively (2 fatal and 3 life-threatening). Phase 3: in only 2 months, 7 serious ADRs were observed prospectively (2 fatal and 1 life-threatening). CONCLUSIONS: Our study shows that among doctors the under-reporting phenomenon is remarkable and it also involves medicinal products subject to additional monitoring and serious ADRs, including deaths.

The effectiveness of medical therapy alone is often limited and endovascular strategy should be considered, particularly in the presence of persisting neurological symptoms. Currently, there is no general consensus on the most appropriate therapeutic strategy to follow in symptomatic carotid artery dissection. We here report a case of symptomatic carotid artery dissection treated with an endovascular approach, and we review the recent literature regarding this therapeutic strategy. Materials and methods for performing endovascular treatment are also described, along with the possible steps to follow. Data in the literature and our clinical experience suggest that stenting is promising in patients with internal carotid artery dissection and should be considered as a valid therapeutic strategy in case of failure of medical therapy in highly experienced centers.

AB - Percutaneous treatment of chronic total occlusions (CTO) is one of the major challenges in contemporary interventional cardiology. These lesions are identified in 15% to 30% of all patients referred for coronary angiography. Percutaneous coronary intervention (PCI) of CTOs is technically challenging and requires familiarity with advanced interventional techniques as well as specialty equipment. The choice of strategy and materials is based on clinical features and coronary anatomy; the correct choice is essential to improve the success probability. PCI of CTOs is usually performed in stable coronary artery disease. We here report a case of a PCI of an anterior descending CTO grafted by a saphenous vein in an 83-year-old man admitted for acute coronary syndrome complicated by hypotensive pulmonary edema. PMID- 29451515 TI - [Promoting evidence-based gastroenterology: back to the future.] AB - Evidence-based medicine continues to thrive thanks to the publication of a considerable amount of papers focusing on data collection and sharing. Assessment of the accuracy of diagnostic tests still remains highly deficient, often leading to inappropriate clinical decision-making. Like most other doctors, gastroenterologists as well have to face the ever-growing availability of complex and expensive exams, being charged with the task of choosing the best diagnostic option and interpreting test results. It is therefore advisable to provide specialists with the tools they need to evaluate the available literature data. Among these, it deserves mentioning the residential courses organized by the Evidence-based Gastroenterology & Hepatology Club, which have been attended by hundreds of participants over the last years. PMID- 29451516 TI - [Evidence-based medicine vs personalized medicine.] AB - Evidence-based medicine (EBM) and personalized medicine (PM) are driven by two diverse modes of reasoning about "evidence making". EBM has been criticized since his quality mark has been misappropriated by vested interests, the benefits statistically significant may be marginal in clinical practice, rigid rules and technology may produce care that is management driven rather than patient centered. On the contrary PM (or "precision medicine") refers to the tailoring of medical treatment to the specific characteristics of each patient involving the ability to classify individuals into subpopulations that are uniquely susceptible to a specific treatment, sparing expense and side effects and is derived from doubts on the results of subgroup analyses and on non responders in clinical trials typical of EBM. While both paradigms are epistemically sound they cannot, and should not, be hybridized into a unique model. Rather they ought to represent two compatible, but alternative ways of informing the Clinical practice. The clinicians may expect to see their responsibility increasing as they will deal with diverse, but equally compelling ways of reasoning and deciding about which intervention will qualify as the "best one" in each individual case.

The most serious form is an acute episode of diverticulitis which can lead to hospitalization and surgery with various types of consequences. The main aim of this study was to evaluate, from both cross-sectional and longitudinal perspective, the economic burden of diverticulitis in the real practice. METHOD: A deterministic linkage was performed at individual user level between the different administrative sources of the Marche Region through anonymised ID number for a period of analysis between 1 January 2008 and 31 December 2014. We enrolled all patients with at least one hospitalization for "diverticulitis of the colon without mention of haemorrhage" (ICD-9-CM code 562.11) or "diverticulitis of the colon with haemorrhage" (ICD-9-CM code 562.13) as primary or secondary diagnosis. Cost and outcome were analysed considering transversally (for contemporaneous) and longitudinal (for cohort) perspective. Hospital mortality at one year after discharge was evaluated by mortality rates and Kaplan-Meier curve considering the surgery performed (or not performed) during the index hospitalization. RESULTS: Considering the cross-sectional perspective, 427 patients per year were estimated (about 35 patients per 100,000 adult residents) with an average number of hospitalization equal to 1.14. The direct healthcare costs incurred by the Marche region for episodes of diverticulitis in 2008-2014 amounted to approximately ? 11.4 million (? 1.6 million a year), of which ? 10.9 million (95.5%) for the hospitalizations, ? 246,000 (2.1%) for pharmaceutical treatment and ? 270,000 (2.4%) for specialist outpatient services. The cohort analysis estimates an intra hospital mortality rate equal to 5.9 per 100 patients' year (5.5 for non-surgery patients and 8.9 for surgery patients - P<0.05). Kaplan-Meier curve demonstrate that there were no differences between intra-hospital mortality due to surgery during index hospitalization. CONCLUSIONS: Our study is the first analysis in Italy to use real-world data to measure the burden of DD with a cross-sectional and longitudinal perspective. This study could be useful for decision maker that could quantify the economic and epidemiological burden of DD in hospital.

An analysis of what has happened over the last three years, especially in Italy, helps us understand how price negotiation has been managed, and what criteria were chosen at first to allow limited access on the basis of the need of patient care. This allows to focus on some important issues and to identify the challenges ahead in the near future. PMID- 29451519 TI - [Hepatitis C virus infections: is it only e liver disease?] AB - Hepatitis C virus (HCV) infection is widely diffused in general population, and the likelihood that an infected individual is affected by other disesases is high. A lot of epidemiological and explicative studies, even if with different levels of evidence, reported a potential effect of HCV infection -by direct and indirect mechanisms- on the pathogenesis of extrahepatic comorbidities related to dysregulation of the immune system, or cardiometabolic comorbidities like diabetes, neuropsychiatric disorders, chronic kidney disease, cardiovascular alterations, etc. Along this line, some studies observed a positive effect of viral eradication on extrahepatic diseases. However, these data are some time affected by selection bias and by the fact that they are mostly focuded on populations underwent interferon-based therapies. Until now only few data are available on the impact of viral eradication by direct antiviral agents on extrahepatic manifestations of HCV. Consistently, to draw conclusions, further validation studies are needed also stratifying the effect of viral eradication according to lenght and severity of both hepatic and extrahepatic damage. PMID- 29451520 TI - [Hepatitis C virus infection. From clinical guidelines to clinical practice and personalization of cure.] AB - Although clinical guidelines provide clear indications on the treatment of patients with chronic HCV related liver disease, there are still clinical situations in which clinicians experience and judgment remain essential in the proper patient management. These are mainly represented by antiviral therapy in patients with decompensated liver disease, especially if they are candidates for liver transplantation or with significant comorbidities and complex pharmacological therapies. Antiviral retreatment of patients who failed a regimen containing an NS5A protease inhibitor still appears to be a delicate context in which no solid recommendations are provided, especially in patients with HCV genotype 3 and decompensated cirrhosis. The follow-up of patients without cirrhosis who have obtained viral eradication is still controversial, in the absence of prospective clinical trials. With the advent of new drugs and shorter treatments in patients with mild liver disease, the subject of discussion and recommendations could become the evaluation of early HCV viral kinetics after the onset of treatment to decide in every patient when to stop antivirals.

Multi-society Italian position paper.] AB - Hepatocellular carcinoma (HCC) is a neoplasm characterized by both clinical and biological heterogeneity. Its management requires the expertise of multiple medical specialists and is made complex by the old age of most patients, frequently showing comorbidities. Therefore, HCC management needs a multidisciplinary approach. The aim of this article is to illustrate multi society recommendations regarding the management of HCC patients, from diagnosis to treatment and follow-up. In particular, in every stage, HCC treatment comprises multiple alternatives and the best option for every patient should be decided by a multidisciplinary team.

The first strategy includes endoscopic dilation using bougies or balloons. Although the immediate success rate of these is up to 90%, about 30-40% of patients experience recurrent dysphagia within the first year of follow-up. The management of refractory stenosis involves repeated sessions of endoscopic dilation. In order to obtain long-lasting functional results, alternative treatments have been developed, such as the use of self-expanding stents, particularly indicated in subgroups of patients with post-surgical stenosis or post-radiation therapy. If this approach fails, other possibilities are represented by self-decoding, PEG/J-tube positioning and, finally, reconstructive surgery.

The conventional therapeutic approach for inflammatory bowel diseases is based mainly on symptom control. Unfortunately, a symptom-based therapeutic approach has little impact on major long-term disease outcomes. In other chronic disabling conditions such as diabetes, hypertension and rheumatoid arthritis, the development of new therapeutic approaches has led to better outcomes. In this context a "treat to target" strategy has been developed. This strategy is based on identification of high-risk patients, regular assessment of disease activity by means of objective measures, adjustment of treatment to reach the pre-defined target. A treat to target approach has recently been proposed for inflammatory bowel disease with the aim at modifying the natural history of the disease. In this review, the evidence and the limitations of the treat to target paradigm in inflammatory bowel disease are analyzed and discussed.

The composition and functions of this "superorganism" are influenced by many factors, and among them, the host's dietary habits seem to have a significant effect. Dietary changes in the evolution of human history and in the different stages of life of the human subjects are responsible for qualitative and functional modification of gut microbiota. At the same time, the different dietary models adopted in worldwide geographic areas take into account the inter-individual differences concerning composition and microbial function. This close relationship between diet, gut microbiota and host seems, in fact, to be responsible for the protection or predisposition to develop several metabolic, immunological, neoplastic and functional diseases. Thus, several studies have evaluated the impact of diet and lifestyle modification strategies on gut microbiota composition and functions which, in turn, seems to affect the effectiveness of such therapeutic measures. Gut microbiota manipulation strategies, as complementary to dietary modifications, represent a fascinating field of research, even if consolidated data are still lacking. PMID- 29451526 TI - ?

Actually, the introduction of a new concept of chronic pancreatitis, now considered as a fibroinflammatory process caused by multiple factors (toxic metabolic, genetic, immunologic, obstructive), allow to better understand the pathogenesis of this complex disease. Furthermore, the discover of peculiar forms of chronic pancreatitis (autoimmune, paraduodenal, associated to gene mutations), different in term of clinical aspects, findings at imaging, prognosis and therapy, radically changed the concept of the disease. In this brief review, we described the impact of this new concept in the comprehension of pathogenesis, in the definition of peculiar forms of chronic pancreatitis, and in the clinical and therapeutic approach of chronic pancreatitis.

AB - [This corrects the article DOI: 10.1210/js.2017-00359.]. PMID- 29451528 TI - Reviewer training to assess knowledge translation in funding applications is long overdue. AB - Background: Health research funding agencies are placing a growing focus on knowledge translation (KT) plans, also known as dissemination and implementation (D&I) plans, in grant applications to decrease the gap between what we know from research and what we do in practice, policy, and further research. Historically, review panels have focused on the scientific excellence of applications to determine which should be funded; however, relevance to societal health priorities, the facilitation of evidence-informed practice and policy, or realizing commercialization opportunities all require a different lens. Discussion: While experts in their respective fields, grant reviewers may lack the competencies to rigorously assess the KT components of applications. Funders of health research-including health charities, non-profit agencies, governments, and foundations-have an obligation to ensure that these components of funding applications are as rigorously evaluated as the scientific components. In this paper, we discuss the need for a more rigorous evaluation of knowledge translation potential by review panels and propose how this may be addressed. Conclusion: We propose that reviewer training supported in various ways including guidelines and KT expertise on review panels and modalities such as online and face-to-face training will result in the rigorous assessment of all components of funding applications, thus increasing the relevance and use of funded research evidence. An unintended but highly welcome consequence of such training could be higher quality D&I or KT plans in subsequent funding applications from trained reviewers. PMID- 29451529 TI - Improving the peer review of narrative literature reviews. AB - As the size of the published scientific literature has increased exponentially over the past 30 years, review articles play an increasingly important role in helping researchers to make sense of original research results. Literature reviews can be broadly classified as either "systematic" or "narrative". Narrative reviews may be broader in scope than systematic reviews, but have been criticised for lacking synthesis and rigour. The submission of more scientific manuscripts requires more researchers acting as peer reviewers, which requires adding greater numbers of new reviewers to the reviewing population over time. However, whereas there are many easily accessible guides for reviewers of primary research manuscripts, there are few similar resources to assist reviewers of narrative reviews. Here, I summarise why literature reviews are valued by their diverse readership and how peer reviewers with different levels of content expertise can improve the reliability and accessibility of narrative review articles. I then provide a number of recommendations for peer reviewers of narrative literature reviews, to improve the integrity of the scientific literature, while also ensuring that narrative review articles meet the needs of both expert and non-expert readers.

AB - Background: To limit selective and incomplete publication of the results of clinical trials, registries including ClinicalTrials.gov were introduced. The ClinicalTrials.gov registry added a results database in 2008 to enable researchers to post the results of their trials as stipulated by the Food and Drug Administration Amendment Act of 2007. This study aimed to determine the direction and magnitude of any change in publication proportions of registered breast cancer trials that occurred since the inception of the ClinicalTrials.gov results database. Methods: A cross-sectional study design was employed using ClinicalTrials.gov, a publicly available registry/results database as the primary data source. Registry contents under the subcategories 'Breast Neoplasms' and 'Breast Neoplasms, Male' were downloaded on 1 August 2015. A literature search for included trials was afterwards conducted using MEDLINE and DISCOVER databases to determine publication status of the registered breast cancer trials. Results: Nearly half (168/340) of the listed trials had been published, with a median time to publication of 24 months (Q1 = 14 months, Q3 = 42 months). Only 86 trials were published within 24 months of completion. There was no significant increase in publication proportions of trials that were completed before the introduction of the results database compared to those completed after (OR = 1.00, 95 % CI = .61 to 1.63; adjusted OR = 0.84, 95 % CI = .51 to 1.39). Characteristics associated with publication included trial type (observational versus interventional adjusted OR = .28, 95 % CI = .10 to .74) and completion/termination status (terminated versus completed adjusted OR = .22, 95 % CI = .09 to .51). Conclusions: Less than a half of breast cancer trials registered in ClinicalTrials.gov are published in peer-reviewed journals.

AB - We have national guidelines for the responsible conduct of research (RCR) and procedures for handling allegations of misconduct in Finland. The guidelines have been formulated and updated by the Finnish Advisory Board on Research Integrity (TENK). In this article, we introduce and evaluate the national RCR guidelines. We also present statistics of alleged and proven RCR violation cases and frequency of appeals to TENK on the decisions or procedures of the primary institutions. In addition, we analyze the available data on seven investigated cases in more detail. Positive aspects in the Finnish system are a fairly good infrastructure to investigate suspected RCR violations and a wide concept of RCR violations, which consists of fabrication, falsification, plagiarism, misappropriation, and other misbehaviors. However, the guidelines contain poorly elaborated definitions, do not treat the complainant and the suspect in an equal way, and need to be revised. Confusion about the concepts and criteria of the RCR violations seems to be common in primary institutions and among the complainants. Even if research institutions and universities have officially adhered to the national RCR guidelines, slipping from the guidelines occurs quite commonly. All these factors lead to frequent dissatisfaction with the decisions or procedures applied, high rate of appeals to TENK, and far from optimal functionality of the system. PMID- 29451532 TI - Using democracy to award research funding: an observational study. AB - Background: Winning funding for health and medical research usually involves a lengthy application process. With success rates under 20%, much of the time spent by 80% of applicants could have been better used on actual research. An alternative funding system that could save time is using democracy to award the most deserving researchers based on votes from the research community. We aimed to pilot how such a system could work and examine some potential biases. Methods: We used an online survey with a convenience sample of Australian researchers. Researchers were asked to name the 10 scientists currently working in Australia that they thought most deserved funding for future research. For comparison, we used recent winners from large national fellowship schemes that used traditional peer review. Results: Voting took a median of 5 min (inter-quartile range 3 to 10 min). Extrapolating to a national voting scheme, we estimate 599 working days of voting time (95% CI 490 to 728), compared with 827 working days for the current peer review system for fellowships. The gender ratio in the votes was a more equal 45:55 (female to male) compared with 34:66 in recent fellowship winners, although this could be explained by Simpson's paradox. Voters were biased towards their own institution, with an additional 1.6 votes per ballot (inter-quartile range 0.8 to 2.2) above the expected number. Respondents raised many concerns about the idea of using democracy to fund research, including vote rigging, lobbying and it becoming a popularity contest. Conclusions: This is a preliminary study of using voting that does not investigate many of the concerns about how a voting system would work. We were able to show that voting would take less time than traditional peer review and would spread the workload over many more reviewers. Further studies of alternative funding systems are needed as well as a wide discussion with the research community about potential changes. PMID- 29451533 TI - Recruitment of reviewers is becoming harder at some journals: a test of the influence of reviewer fatigue at six journals in ecology and evolution. AB - Background: It is commonly reported by editors that it has become harder to recruit reviewers for peer review and that this is because individuals are being asked to review too often and are experiencing reviewer fatigue. However, evidence supporting these arguments is largely anecdotal. Main body: We examine responses of individuals to review invitations for six journals in ecology and evolution. The proportion of invitations that lead to a submitted review has been decreasing steadily over 13 years (2003-2015) for four of the six journals examined, with a cumulative effect that has been quite substantial (average decline from 56% of review invitations generating a review in 2003 to just 37% in 2015). The likelihood that an invitee agrees to review declines significantly with the number of invitations they receive in a year. However, the average number of invitations being sent to prospective reviewers and the proportion of individuals being invited more than once per year has not changed much over these 13 years, despite substantial increases in the total number of review invitations being sent by these journals-the reviewer base has expanded concomitant with this growth in review requests. Conclusions: The proportion of review invitations that lead to a review being submitted has been declining steadily for four of the six journals examined here, but reviewer fatigue is not likely the primary explanation for this decline. PMID- 29451534 TI - Simple decision-tree tool to facilitate author identification of reporting guidelines during submission: a before-after study. AB - Background: There is evidence that direct journal endorsement of reporting guidelines can lead to important improvements in the quality and reliability of the published research. However, over the last 20 years, there has been a proliferation of reporting guidelines for different study designs, making it impractical for a journal to explicitly endorse them all. The objective of this study was to investigate whether a decision tree tool made available during the submission process facilitates author identification of the relevant reporting guideline. Methods: This was a prospective 14-week before-after study across four speciality medical research journals. During the submission process, authors were prompted to follow the relevant reporting guideline from the EQUATOR Network and asked to confirm that they followed the guideline ('before'). After 7 weeks, this prompt was updated to include a direct link to the decision-tree tool and an additional prompt for those authors who stated that 'no guidelines were applicable' ('after'). For each article submitted, the authors' response, what guideline they followed (if any) and what reporting guideline they should have followed (including none relevant) were recorded. Results: Overall, 590 manuscripts were included in this analysis-300 in the before cohort and 290 in the after. There were relevant reporting guidelines for 75% of manuscripts in each group; STROBE was the most commonly applicable reporting guideline, relevant for 35% (n = 106) and 37% (n = 106) of manuscripts, respectively. Use of the tool was associated with an 8.4% improvement in the number of authors correctly identifying the relevant reporting guideline for their study (p < 0.0001), a 14% reduction in the number of authors incorrectly stating that there were no relevant reporting guidelines (p < 0.0001), and a 1.7% reduction in authors choosing a guideline (p = 0.10). However, the 'after' cohort also saw a significant increase in the number of authors stating that there were relevant reporting guidelines for their study, but not specifying which (34 vs 29%; p = 0.04). Conclusion: This study suggests that use of a decision-tree tool during submission of a manuscript is associated with improved author identification of the relevant reporting guidelines for their study type; however, the majority of authors still failed to correctly identify the relevant guidelines. PMID- 29451535 TI - Updating standards for reporting diagnostic accuracy: the development of STARD 2015. AB - Background: Although the number of reporting guidelines has grown rapidly, few have gone through an updating process. The STARD statement (Standards for Reporting Diagnostic Accuracy), published in 2003 to help improve the transparency and completeness of reporting of diagnostic accuracy studies, was recently updated in a systematic way. Here, we describe the steps taken and a justification for the changes made. Results: A 4-member Project Team coordinated the updating process; a 14-member Steering Committee was regularly solicited by the Project Team when making critical decisions. First, a review of the literature was performed to identify topics and items potentially relevant to the STARD updating process. After this, the 85 members of the STARD Group were invited to participate in two online surveys to identify items that needed to be modified, removed from, or added to the STARD checklist. Based on the results of the literature review process, 33 items were presented to the STARD Group in the online survey: 25 original items and 8 new items; 73 STARD Group members (86 %) completed the first survey, and 79 STARD Group members (93 %) completed the second survey.Then, an in-person consensus meeting was organized among the members of the Project Team and Steering Committee to develop a consensual draft version of STARD 2015. This version was piloted in three rounds among a total of 32 expert and non-expert users. Piloting mostly led to rewording of items. After this, the update was finalized. The updated STARD 2015 list now consists of 30 items. Compared to the previous version of STARD, three original items were each converted into two new items, four original items were incorporated into other items, and seven new items were added. Conclusions: After a systematic updating process, STARD 2015 provides an updated list of 30 essential items for reporting diagnostic accuracy studies. PMID- 29451536 TI - Percentage-based Author Contribution Index: a universal measure of author contribution to scientific articles. AB - Background: Deciphering the amount of work provided by different co-authors of a scientific paper has been a recurrent problem in science. Despite the myriad of metrics available, the scientific community still largely relies on the position in the list of authors to evaluate contributions, a metric that attributes subjective and unfounded credit to co-authors. We propose an easy to apply, universally comparable and fair metric to measure and report co-authors contribution in the scientific literature. Methods: The proposed Author Contribution Index (ACI) is based on contribution percentages provided by the authors, preferably at the time of submission. Researchers can use ACI to compare the contributions of different authors, describe the contribution profile of a particular researcher or analyse how contribution changes through time. We provide such an analysis based on contribution percentages provided by 97 scientists from the field of ecology who voluntarily responded to an online anonymous survey. Results: ACI is simple to understand and to implement because it is based solely on percentage contributions and the number of co-authors. It provides a continuous score that reflects the contribution of one author as compared to the average contribution of all other authors. For example, ACI(i) = 3, means that author i contributed three times more than what the other authors contributed on average. Our analysis comprised 836 papers published in 2014-2016 and revealed patterns of ACI values that relate to career advancement. Conclusion: There are many examples of author contribution indices that have been proposed but none has really been adopted by scientific journals. Many of the proposed solutions are either too complicated, not accurate enough or not comparable across articles, authors and disciplines. The author contribution index presented here addresses these three major issues and has the potential to contribute to more transparency in the science literature. If adopted by scientific journals, it could provide job seekers, recruiters and evaluating bodies with a tool to gather information that is essential to them and cannot be easily and accurately obtained otherwise. We also suggest that scientists use the index regardless of whether it is implemented by journals or not. PMID- 29451537 TI - Improving the process of research ethics review. AB - Background: Research Ethics Boards, or Institutional Review Boards, protect the safety and welfare of human research participants. These bodies are responsible for providing an independent evaluation of proposed research studies, ultimately ensuring that the research does not proceed unless standards and regulations are met. Main body: Concurrent with the growing volume of human participant research, the workload and responsibilities of Research Ethics Boards (REBs) have continued to increase. Dissatisfaction with the review process, particularly the time interval from submission to decision, is common within the research community, but there has been little systematic effort to examine REB processes that may contribute to inefficiencies. We offer a model illustrating REB workflow, stakeholders, and accountabilities. Conclusion: Better understanding of the components of the research ethics review will allow performance targets to be set, problems identified, and solutions developed, ultimately improving the process.

PMID- 29451540 TI - Developing the Clarity and Openness in Reporting: E3-based (CORE) Reference user manual for creation of clinical study reports in the era of clinical trial transparency. AB - Background: Interventional clinical studies conducted in the regulated drug research environment are reported using International Council for Harmonisation (ICH) regulatory guidance documents: ICH E3 on the structure and content of clinical study reports (CSRs) published in 1995 and ICH E3 supplementary Questions & Answers (Q & A) published in 2012.Since the ICH guidance documents were published, there has been heightened awareness of the importance of disclosure of clinical study results. The use of the CSR as a key source document to fulfil emerging obligations has resulted in a re-examination of how ICH guidelines are applied in CSR preparation. The dynamic regulatory and modern drug development environments create emerging reporting challenges. Methods: Regulatory medical writing and statistical professionals developed Clarity and Openness in Reporting: E3-based (CORE) Reference over a 2-year period. Stakeholders contributing expertise included a global industry association, regulatory agency, patient advocate, academic and Principal Investigator representatives. Results: CORE Reference should help authors navigate relevant guidelines as they create CSR content relevant for today's studies. It offers practical suggestions for developing CSRs that will require minimum redaction and modification prior to public disclosure.CORE Reference comprises a Preface, followed by the actual resource. The Preface clarifies intended use and underlying principles that inform resource utility. The Preface lists references contributing to development of the resource, which broadly fall into 'regulatory' and 'public disclosure' categories. The resource includes ICH E3 guidance text, ICH E3 Q & A 2012-derived guidance text and CORE Reference text, distinguished from one another through the use of shading. Rationale comments are used throughout for clarification purposes.A separate mapping tool comparing ICH E3 sectional structure and CORE Reference sectional structure is also provided.Together, CORE Reference and the mapping tool constitute the user manual. Conclusions: This publication is intended to enhance the use, understanding and dissemination of CORE Reference.The CORE Reference user manual and the associated website (http://www.core-reference.org) should improve the reporting of interventional clinical studies.Periodic updates of CORE Reference are planned to maintain its relevance. Registration: CORE Reference was registered with http://www.equator-network.org on 23 March 2015. PMID- 29451541 TI - Publishing descriptions of non-public clinical datasets: proposed guidance for researchers, repositories, editors and funding organisations. AB - Sharing of experimental clinical research data usually happens between individuals or research groups rather than via public repositories, in part due to the need to protect research participant privacy. This approach to data sharing makes it difficult to connect journal articles with their underlying datasets and is often insufficient for ensuring access to data in the long term. Voluntary data sharing services such as the Yale Open Data Access (YODA) and Clinical Study Data Request (CSDR) projects have increased accessibility to clinical datasets for secondary uses while protecting patient privacy and the legitimacy of secondary analyses but these resources are generally disconnected from journal articles-where researchers typically search for reliable information to inform future research. New scholarly journal and article types dedicated to increasing accessibility of research data have emerged in recent years and, in general, journals are developing stronger links with data repositories. There is a need for increased collaboration between journals, data repositories, researchers, funders, and voluntary data sharing services to increase the visibility and reliability of clinical research. Using the journal Scientific Data as a case study, we propose and show examples of changes to the format and peer-review process for journal articles to more robustly link them to data that are only available on request. We also propose additional features for data repositories to better accommodate non-public clinical datasets, including Data Use Agreements (DUAs). PMID- 29451542 TI - Propagation of errors in citation networks: a study involving the entire citation network of a widely cited paper published in, and later retracted from, the journal Nature. AB - Background: In about one in 10,000 cases, a published article is retracted. This very often means that the results it reports are flawed. Several authors have voiced concerns about the presence of retracted research in the memory of science. In particular, a retracted result is propagated by citing it. In the published literature, many instances are given of retracted articles that are cited both before and after their retraction. Even worse is the possibility that these articles in turn are cited in such a way that the retracted result is propagated further. Methods: We have conducted a case study to find out how a retracted article is cited and whether retracted results are propagated through indirect citations. We have constructed the entire citation network for this case. Results: We show that directly citing articles is an important source of propagation of retracted research results. In contrast, in our case study, indirect citations do not contribute to the propagation of the retracted result. Conclusions: While admitting the limitations of a study involving a single case, we think there are reasons for the non-contribution of indirect citations that hold beyond our case study. PMID- 29451543 TI - Sex and Gender Equity in Research: rationale for the SAGER guidelines and recommended use. AB - Background: Sex and gender differences are often overlooked in research design, study implementation and scientific reporting, as well as in general science communication. This oversight limits the generalizability of research findings and their applicability to clinical practice, in particular for women but also for men. This article describes the rationale for an international set of guidelines to encourage a more systematic approach to the reporting of sex and gender in research across disciplines. Methods: A panel of 13 experts representing nine countries developed the guidelines through a series of teleconferences, conference presentations and a 2-day workshop. An internet survey of 716 journal editors, scientists and other members of the international publishing community was conducted as well as a literature search on sex and gender policies in scientific publishing. Results: The Sex and Gender Equity in Research (SAGER) guidelines are a comprehensive procedure for reporting of sex and gender information in study design, data analyses, results and interpretation of findings. Conclusions: The SAGER guidelines are designed primarily to guide authors in preparing their manuscripts, but they are also useful for editors, as gatekeepers of science, to integrate assessment of sex and gender into all manuscripts as an integral part of the editorial process.

We discuss how the idea to launch this journal came about and identify the gaps in knowledge where we would like to encourage more research and interdisciplinary discussion. We are particularly keen to receive submissions presenting actual research that will increase our understanding and suggest potential solutions to issues related to peer review, study reporting, and research and publication ethics. PMID- 29451545 TI - Text recycling in health sciences research literature: a rhetorical perspective. AB - The past few years have seen a steady rise in the number of health science journals using plagiarism detection software to screen submitted manuscripts. While there is widespread agreement about the need to guard against plagiarism and duplicate publication, the use of such tools has sparked debate about text recycling-the reuse of material from one's prior publications in a new manuscript. Many who have published on the topic consider all uses of text recycling anathema. Others argue that some uses of recycling are unavoidable and sometimes even beneficial for readers. Unfortunately, much of this discourse now merely repeats dogmatic assertions. I argue that progress can be made by acknowledging three points: First, citation standards for research writing in the health sciences will not mirror those of the humanities. Second, while it is impossible to draw a definitive line between appropriate and inappropriate uses of text recycling, some uses of the practice lie clearly on the legitimate side. Third, the needs of editors for information regarding recycled text are different from those of readers. Ultimately, calls for rewording and citation as alternatives or fixes for text recycling are unlikely to prove satisfactory to either readers or editors.

PMID- 29451546 TI - The high costs of getting ethical and site-specific approvals for multi-centre research. AB - Background: Multi-centre studies generally cost more than single-centre studies because of larger sample sizes and the need for multiple ethical approvals. Multi centre studies include clinical trials, clinical quality registries, observational studies and implementation studies. We examined the costs of two large Australian multi-centre studies in obtaining ethical and site-specific approvals. Methods: We collected data on staff time spent on approvals and expressed the overall cost as a percent of the total budget. Results: The total costs of gaining approval were 38 % of the budget for a study of 50 centres (mean cost AUD $6960 per site) and 2 % for a study of 11 centres (mean cost AUD $2300 per site). Seventy-five and 90 % of time was spent on repeated tasks, respectively, and many time-consuming tasks, such as reformatting documents, did nothing to improve the study design or participant safety. Conclusions: Improvements have been made to the ethical approval application system, but more gains could be made without increasing risks of harm to research participants. We propose that ethical review bodies and individual sites publish statistics on how long they take to process approvals which could then be nationally benchmarked. PMID- 29451548 TI - 'Are you siding with a personality or the grant proposal?': observations on how peer review panels function. AB - Background: In Australia, the peer review process for competitive funding is usually conducted by a peer review group in conjunction with prior assessment from external assessors. This process is quite mysterious to those outside it. The purpose of this research was to throw light on grant review panels (sometimes called the 'black box') through an examination of the impact of panel procedures, panel composition and panel dynamics on the decision-making in the grant review process. A further purpose was to compare experience of a simplified review process with more conventional processes used in assessing grant proposals in Australia. Methods: This project was one aspect of a larger study into the costs and benefits of a simplified peer review process. The Queensland University of Technology (QUT)-simplified process was compared with the National Health and Medical Research Council's (NHMRC) more complex process. Grant review panellists involved in both processes were interviewed about their experience of the decision-making process that assesses the excellence of an application. All interviews were recorded and transcribed. Each transcription was de-identified and returned to the respondent for review. Final transcripts were read repeatedly and coded, and similar codes were amalgamated into categories that were used to build themes. Final themes were shared with the research team for feedback. Results: Two major themes arose from the research: (1) assessing grant proposals and (2) factors influencing the fairness, integrity and objectivity of review. Issues such as the quality of writing in a grant proposal, comparison of the two review methods, the purpose and use of the rebuttal, assessing the financial value of funded projects, the importance of the experience of the panel membership and the role of track record and the impact of group dynamics on the review process were all discussed. The research also examined the influence of research culture on decision-making in grant review panels. One of the aims of this study was to compare a simplified review process with more conventional processes. Generally, participants were supportive of the simplified process. Conclusions: Transparency in the grant review process will result in better appreciation of the outcome. Despite the provision of clear guidelines for peer review, reviewing processes are likely to be subjective to the extent that different reviewers apply different rules. The peer review process will come under more scrutiny as funding for research becomes even more competitive. There is justification for further research on the process, especially of a kind that taps more deeply into the 'black box' of peer review. PMID- 29451547 TI - Selective citation in the literature on swimming in chlorinated water and childhood asthma: a network analysis. AB - Background: Knowledge development depends on an unbiased representation of the available evidence. Selective citation may distort this representation. Recently, some controversy emerged regarding the possible impact of swimming on childhood asthma, raising the question about the role of selective citation in this field. Our objective was to assess the occurrence and determinants of selective citation in scientific publications on the relationship between swimming in chlorinated pools and childhood asthma. Methods: We identified scientific journal articles on this relationship via a systematic literature search. The following factors were taken into account: study outcome (authors' conclusion, data-based conclusion), other content-related article characteristics (article type, sample size, research quality, specificity), content-unrelated article characteristics (language, publication title, funding source, number of authors, number of affiliations, number of references, journal impact factor), author characteristics (gender, country, affiliation), and citation characteristics (time to citation, authority, self-citation). To assess the impact of these factors on citation, we performed a series of univariate and adjusted random effects logistic regressions, with potential citation path as unit of analysis. Results: Thirty-six articles were identified in this network, consisting of 570 potential citation paths of which 191 (34%) were realized. There was strong evidence that articles with at least one author in common, cited each other more often than articles that had no common authors (odds ratio (OR) 5.2, 95% confidence interval (CI) 3.1-8.8). Similarly, the chance of being cited was higher for articles that were empirical rather than narrative (OR 4.2, CI 2.6 6.7), that reported a large sample size (OR 5.8, CI 2.9-11.6), and that were written by authors with a high authority within the network (OR 4.1, CI 2.1-8.0). Further, there was some evidence for citation bias: articles that confirmed the relation between swimming and asthma were cited more often (OR 1.8, CI 1.1-2.9), but this finding was not robust. Conclusions: There is clear evidence of selective citation in this research field, but the evidence for citation bias is not very strong. PMID- 29451549 TI - Retractions in cancer research: a systematic survey. AB - Background: The annual number of retracted publications in the scientific literature is rapidly increasing. The objective of this study was to determine the frequency and reason for retraction of cancer publications and to determine how journals in the cancer field handle retracted articles. Methods: We searched three online databases (MEDLINE, Embase, The Cochrane Library) from database inception until 2015 for retracted journal publications related to cancer research. For each article, the reason for retraction was categorized as plagiarism, duplicate publication, fraud, error, authorship issues, or ethical issues. Accessibility of the retracted article was defined as intact, removed, or available but with a watermark over each page. Descriptive data was collected on each retracted article including number of citations, journal name and impact factor, study design, and time between publication and retraction. The publications were screened in duplicated and two reviewers extracted and categorized data. Results: Following database search and article screening, we identified 571 retracted cancer publications. The majority (76.4%) of cancer retractions were issued in the most recent decade, with 16.6 and 6.7% of the retractions in the prior two decades respectively. Retractions were issued by journals with impact factors ranging from 0 (discontinued) to 55.8. The average impact factor was 5.4 (median 3.54, IQR 1.8-5.5). On average, a retracted article was cited 45 times (median 18, IQR 6-51), with a range of 0-742. Reasons for retraction include plagiarism (14.4%), fraud (28.4%), duplicate publication (18.2%), error (24.2%), authorship issues (3.9%), and ethical issues (2.1%). The reason for retraction was not stated in 9.8% of cases. Twenty-nine percent of retracted articles remain available online in their original form. Conclusions: Retractions in cancer research are increasing in frequency at a similar rate to all biomedical research retractions. Cancer retractions are largely due to academic misconduct. Consequences to cancer patients, the public at large, and the research community can be substantial and should be addressed with future research. Despite the implications of this important issue, some cancer journals currently fall short of the current guidelines for clearly stating the reason for retraction and identifying the publication as retracted.

AB - Background: The aim of this survey was to determine the level of awareness and understanding of peer review and peer review models amongst junior hospital doctors and whether this influences clinical decision-making. Methods: A 30 question online anonymous survey was developed aimed at determining awareness of peer review models and the purpose of peer review, perceived trustworthiness of different peer review models and the role of peer review in clinical decision making. It was sent to 800 trainee doctors in medical specialties on the University College London Partners trainee database. Results: The response rate was (178/800) 22%. Most respondents were specialist registrars. Checking that research is conducted correctly (152/178, 85%) and the data interpreted correctly (148/178, 83%) were viewed as the most important purposes of peer review. Most respondents were aware of open (133/178, 75%), double-blind (125/178, 70%) and single-blind peer review (121/178, 68%). 101/178 (57%) had heard of collaborative, 87/178 (49%) of post publication and 29/178 (16%) of decoupled peer review. Of those who were aware of double-blind, single-blind open and collaborative peer review, 85 (68%), 82 (68%), 74 (56%) and 24 (24%), respectively, understood how they worked. The NEJM, Lancet and The BMJ were deemed to have most trustworthy peer review, 137/178 (77%), 129/178 (72%) and 115/178 (65%), respectively. That peer review had taken place was important for a journal content to be used for clinical decision-making 152/178 (85%), but the ability to see peer review reports was not as important 22/178 (12%). Most felt there was a need for peer review training and that this should be at the specialist registrar stage of training. Conclusions: Junior hospital doctors view peer review to be important as a means of quality control, but do not value the ability to scrutinize peer review themselves. The unquestioning acceptance of peer review as final validation in the field of medicine emphasises not only the responsibility held by medical journals to ensure peer review is done well but also the need to raise awareness amongst the medical community of the limitations of the current peer review process. PMID- 29451551 TI - Ranking major and minor research misbehaviors: results from a survey among participants of four World Conferences on Research Integrity. AB - Background: Codes of conduct mainly focus on research misconduct that takes the form of fabrication, falsification, and plagiarism. However, at the aggregate level, lesser forms of research misbehavior may be more important due to their much higher prevalence. Little is known about what the most frequent research misbehaviors are and what their impact is if they occur. Methods: A survey was conducted among 1353 attendees of international research integrity conferences. They were asked to score 60 research misbehaviors according to their views on and perceptions of the frequency of occurrence, preventability, impact on truth (validity), and impact on trust between scientists on 5-point scales. We expressed the aggregate level impact as the product of frequency scores and truth, trust and preventability scores, respectively. We ranked misbehaviors based on mean scores. Additionally, relevant demographic and professional background information was collected from participants. Results: Response was 17% of those who were sent the invitational email and 33% of those who opened it. The rankings suggest that selective reporting, selective citing, and flaws in quality assurance and mentoring are viewed as the major problems of modern research. The "deadly sins" of fabrication and falsification ranked highest on the impact on truth but low to moderate on aggregate level impact on truth, due to their low estimated frequency. Plagiarism is thought to be common but to have little impact on truth although it ranked high on aggregate level impact on trust. Conclusions: We designed a comprehensive list of 60 major and minor research misbehaviors. Our respondents were much more concerned over sloppy science than about scientific fraud (FFP). In the fostering of responsible conduct of research, we recommend to develop interventions that actively discourage the high ranking misbehaviors from our study. PMID- 29451552 TI - Plagiarism in submitted manuscripts: incidence, characteristics and optimization of screening-case study in a major specialty medical journal. AB - Background: Plagiarism is common and threatens the integrity of the scientific literature. However, its detection is time consuming and difficult, presenting challenges to editors and publishers who are entrusted with ensuring the integrity of published literature. Methods: In this study, the extent of plagiarism in manuscripts submitted to a major specialty medical journal was documented. We manually curated submitted manuscripts and deemed an article contained plagiarism if one sentence had 80 % of the words copied from another published paper. Commercial plagiarism detection software was utilized and its use was optimized. Results: In 400 consecutively submitted manuscripts, 17 % of submissions contained unacceptable levels of plagiarized material with 82 % of plagiarized manuscripts submitted from countries where English was not an official language. Using the most commonly employed commercial plagiarism detection software, sensitivity and specificity were studied with regard to the generated plagiarism score. The cutoff score maximizing both sensitivity and specificity was 15 % (sensitivity 84.8 % and specificity 80.5 %). Conclusions: Plagiarism was a common occurrence among manuscripts submitted for publication to a major American specialty medical journal and most manuscripts with plagiarized material were submitted from countries in which English was not an official language. The use of commercial plagiarism detection software can be optimized by selecting a cutoff score that reflects desired sensitivity and specificity. PMID- 29451553 TI - Registration of randomized controlled trials in nursing journals. AB - Background: Trial registration helps minimize publication and reporting bias. In leading medical journals, 96% of published trials are registered. The aim of this study was to determine the proportion of randomized controlled trials published in key nursing journals that met criteria for timely registration. Methods: We reviewed all RCTs published in three (two general, one mental health) nursing journals between August 2011 and September 2016. We classified the included trials as: 1. Not registered, 2. Registered but not reported in manuscript, 3. Registered retrospectively, 4. Registered prospectively (before the recruitment of the first subject into the trial). 5. Timely registration (as 4 but the trial identification number is reported in abstract). Results: We identified 135 trials published in the three included journals. The majority (n = 78, 58%) were not registered. Thirty-three (24%) were retrospectively registered. Of the 24 (18%) trials that were prospectively registered, 11 (8%) met the criteria for timely registration. Conclusions: There is an unacceptable difference in rates of trial registration between leading medical and nursing journals. Concerted effort is required by nurse researchers, reviewers and journal editors to ensure that all trials are registered in a timely way. PMID- 29451554 TI - Is it becoming harder to secure reviewers for peer review? A test with data from five ecology journals. AB - Background: There is concern in the academic publishing community that it is becoming more difficult to secure reviews for peer-reviewed manuscripts, but much of this concern stems from anecdotal and rhetorical evidence. Methods: We examined the proportion of review requests that led to a completed review over a 6-year period (2009-2015) in a mid-tier biology journal (Molecular Ecology). We also re-analyzed previously published data from four other mid-tier ecology journals (Functional Ecology, Journal of Ecology, Journal of Animal Ecology, and Journal of Applied Ecology), looking at the same proportion over the period 2003 to 2010. Results: The data from Molecular Ecology showed no significant decrease through time in the proportion of requests that led to a review (proportion in 2009 = 0.47 (95 % CI = 0.43 to 0.52), proportion in 2015 = 0.44 (95 % CI = 0.40 to 0.48)). This proportion did decrease for three of the other ecology journals (changes in proportions from 2003 to 2010 = -0.10, -0.18, and -0.09), while the proportion for the fourth (Functional Ecology) stayed roughly constant (change in proportion = -0.04). Conclusions: Overall, our data suggest that reviewer agreement rates have probably declined slightly but not to the extent suggested by the anecdotal and rhetorical evidence. PMID- 29451555 TI - Mentored peer review of standardized manuscripts as a teaching tool for residents: a pilot randomized controlled multi-center study. AB - Background: There is increasing need for peer reviewers as the scientific literature grows. Formal education in biostatistics and research methodology during residency training is lacking. In this pilot study, we addressed these issues by evaluating a novel method of teaching residents about biostatistics and research methodology using peer review of standardized manuscripts. We hypothesized that mentored peer review would improve resident knowledge and perception of these concepts more than non-mentored peer review, while improving review quality. Methods: A partially blinded, randomized, controlled multi-center study was performed. Seventy-eight neurology residents from nine US neurology programs were randomized to receive mentoring from a local faculty member or not. Within a year, residents reviewed a baseline manuscript and four subsequent manuscripts, all with introduced errors designed to teach fundamental review concepts. In the mentored group, mentors discussed completed reviews with residents. Primary outcome measure was change in knowledge score between pre- and post-tests, measuring epidemiology and biostatistics knowledge. Secondary outcome measures included level of confidence in the use and interpretation of statistical concepts before and after intervention, and RQI score for baseline and final manuscripts. Results: Sixty-four residents (82%) completed initial review with gradual decline in completion on subsequent reviews. Change in primary outcome, the difference between pre- and post-test knowledge scores, did not differ between mentored (-8.5%) and non-mentored (-13.9%) residents (p = 0.48). Significant differences in secondary outcomes (using 5-point Likert scale, 5 = strongly agree) included mentored residents reporting enhanced understanding of research methodology (3.69 vs 2.61; p = 0.001), understanding of manuscripts (3.73 vs 2.87; p = 0.006), and application of study results to clinical practice (3.65 vs 2.78; p = 0.005) compared to non-mentored residents. There was no difference between groups in level of interest in peer review (3.00 vs 3.09; p = 0.72) or the quality of manuscript review assessed by the Review Quality Instrument (RQI) (3.25 vs 3.06; p = 0.50). Conclusions: We used mentored peer review of standardized manuscripts to teach biostatistics and research methodology and introduce the peer review process to residents. Though knowledge level did not change, mentored residents had enhanced perception in their abilities to understand research methodology and manuscripts and apply study results to clinical practice. PMID- 29451556 TI - Factors associated with online media attention to research: a cohort study of articles evaluating cancer treatments. AB - Background: New metrics have been developed to assess the impact of research and provide an indication of online media attention and data dissemination. We aimed to describe online media attention of articles evaluating cancer treatments and identify the factors associated with high online media attention. Methods: We systematically searched MEDLINE via PubMed on March 1, 2015 for articles published during the first 6 months of 2014 in oncology and medical journals with a diverse range of impact factors, from 3.9 to 54.4, and selected a sample of articles evaluating a cancer treatment regardless of study design. Altmetric Explorer was used to identify online media attention of selected articles. The primary outcome was media attention an article received online as measured by Altmetric score (i.e., number of mentions in online news outlets, science blogs and social media). Regression analysis was performed to investigate the factors associated with high media attention, and regression coefficients represent the logarithm of ratio of mean (RoM) values of Altmetric score per unit change in the covariate. Results: Among 792 articles, 218 (27.5%) received no online media attention (Altmetric score = 0). The median [Q1-Q3] Altmetric score was 2.0 [0.0 8.0], range 0.0-428.0. On multivariate analysis, factors associated with high Altmetric score were presence of a press release (RoM = 10.14, 95%CI [4.91 20.96]), open access to the article (RoM = 1.48, 95%CI [1.02-2.16]), and journal impact factor (RoM = 1.10, 95%CI [1.07-1.12]. As compared with observational studies, systematic reviews were not associated with high Altmetric score (RoM = 1.46, 95%CI [0.74-2.86]; P = 0.27), nor were RCTs (RoM = 0.65, 95%CI [0.41-1.02]; P = 0.059) and phase I/II non-RCTs (RoM = 0.58, 95%CI [0.33-1.05]; P = 0.07). The articles with abstract conclusions favouring study treatments were not associated with high Altmetric score (RoM = 0.97, 95%CI [0.60-1.58]; P = 0.91). Conclusions: Most important factors associated with high online media attention were the presence of a press release and the journal impact factor. There was no evidence that study design with high level of evidence and type of abstract conclusion were associated with high online media attention. PMID- 29451557 TI - Biomedical journal speed and efficiency: a cross-sectional pilot survey of author experiences. AB - Background: Although the peer review process is believed to ensure scientific rigor, enhance research quality, and improve manuscript clarity, many investigators are concerned that the process is too slow, too expensive, too unreliable, and too static. In this feasibility study, we sought to survey corresponding authors of recently published clinical research studies on the speed and efficiency of the publication process. Methods: Web-based survey of corresponding authors of a 20% random sample of clinical research studies in MEDLINE-indexed journals with Ovid MEDLINE entry dates between December 1 and 15, 2016. Survey addressed perceived manuscript importance before first submission, approximate first submission and final acceptance dates, and total number of journal submissions, external peer reviews, external peer reviewers, and revisions requested, as well as whether authors would have considered publicly sharing their manuscript on an online platform instead of submitting to a peer reviewed journal. Results: Of 1780 surveys distributed, 27 corresponding authors opted out or requested that we stop emailing them and 149 emails failed (e.g., emails that bounced n = 64, returned with an away from office message n = 70, or were changed/incorrect n = 15), leaving 1604 respondents, of which 337 completed the survey (21.0%). Respondents and non-respondents were similar with respect to study type and publication journals' impact factor, although non-respondent authors had more publications (p = 0.03). Among respondents, the median impact factor of the publications' journal was 2.7 (interquartile range (IQR), 2.0-3.6) and corresponding authors' median h-index and number of publications was 9 (IQR, 3-20) and 27 (IQR, 10-77), respectively. The median time from first submission to journal acceptance and publication was 5 months (IQR, 3-8) and 7 months (IQR, 5 12), respectively. Most respondents (62.0%, n = 209) rated the importance of their research as a 4 or 5 (5-point scale) prior to submission. Median number of journal submissions was 1 (IQR, 1-2), external peer reviews was 1 (IQR, 1-2), external peer reviewers was 3 (IQR, 2-4), and revisions requested was 1 (IQR, 1 1). Sharing manuscripts to a public online platform, instead of submitting to a peer-reviewed journal, would have been considered by 55.2% (n = 186) of respondents. Conclusion: Corresponding authors have high perceptions of their research and reported requiring few manuscript submissions prior to journal acceptance, most commonly by lower impact factor journals. PMID- 29451558 TI - Do declarative titles affect readers' perceptions of research findings? A randomized trial. AB - Background: Many journals prohibit the use of declarative titles that state study findings, yet a few journals encourage or even require them. We compared the effects of a declarative versus a descriptive title on readers' perceptions about the strength of evidence in a research abstract describing a randomized trial. Methods: Study participants (medical or dental students or doctors attending lectures) read two abstracts describing studies of a fictitious treatment (Anticox) for a fictitious condition (Green's syndrome). The first abstract (A1) described an uncontrolled, 10-patient, case series, and the second (A2) described a randomized, placebo-controlled trial involving 48 patients. All participants rated identical A1 abstracts (with a descriptive title) to provide baseline ratings and thus reduce the effects of inter-individual variability. Participants were randomized so that half rated a version of A2 with a descriptive title and half with a declarative title. For each abstract, participants indicated their agreement with the statement "Anticox is an effective treatment for pain in Green's syndrome" using 100 mm visual analogue scales (VAS) ranging from "disagree completely" to "agree completely." VAS scores were measured by an investigator who was unaware of group allocation. Results: One hundred forty-four participants from four centres completed the study. There was no significant difference between the declarative and the descriptive title groups' confidence in the study conclusions as expressed on VAS scales-in fact, the mean difference between A1 and A2 was smaller for the declarative title group than that for the descriptive title group (32.6 mm, SD 27.4 vs. 39.8 mm, SD 22.6, respectively, p = 0.09). Conclusions: We found no evidence that the use of a declarative title affected readers' perceptions about study conclusions. This suggests that editors' fears that declarative titles might unduly influence readers' judgements about study conclusions may be unfounded, at least in relation to reports of randomized trials. However, our study design had several limitations, and our findings may not be generalizable to other situations. PMID- 29451559 TI - Linking chromatin dynamics, cell fate plasticity, and tissue homeostasis in adult mouse hair follicle stem cells. AB - Cellular plasticity for fate acquisition is associated with distinct chromatin states, which include histone modifications, dynamic association of chromatin factors with the DNA, and global chromatin compaction and nuclear organization. While embryonic stem cell (ESC) plasticity in vitro and its link with chromatin states have been characterized in depth, little is known about tissue stem cell plasticity in vivo, during adult tissue homeostasis. Recently, we reported a distinct globally low level of histone H3 K4/9/27me3 in mouse hair follicle stem cells (HFSCs) during quiescence. This occurred at the stage preceding fate acquisition, when HFSC fate plasticity must be at its highest. This hypomethylated state was required for proper skin homeostasis and timely hair cycle. Here, we show both in the live tissue and in cell culture that at quiescence HFSCs have higher exchange rates for core histone H2B when compared with proliferative or differentiated cells. This denoted a hyperdynamic chromatin state, which was previously associated with high cell fate plasticity in ESCs. Moreover, we find that quiescent HFSCs display a higher propensity for de differentiation in response to Yamanaka's reprogramming factors in vivo. These results further support our recent model in which HFSCs render their chromatin into a specific state at quiescence, which is attuned to higher cell fate plasticity. PMID- 29451560 TI - Long noncoding RNAs and their roles in skeletal muscle fate determination. AB - Myogenic fate determination is important in skeletal muscle development, growth and repair. A variety of factors regulate myogenic cell determination via transcriptional and non-transcriptional mechanisms. Amongst these factors, long noncoding RNAs (lncRNAs) have gained considerable attention for their important roles in regulating myogenic differentiation and function. Many classes of lncRNAs have been discovered; various lncRNAs have been implicated in the regulation of myogenic cell fate determination and are the subject of this brief review. PMID- 29451562 TI - Comment on Cary Moskovitz' "Text Recycling in Health Sciences Literature: A Rhetorical Perspective". AB - The question of covert text recycling from previous publications is discussed. It is argued that, consistent with current guidance, authors may be allowed to covertly recycle a limited amount of their previously published material but mainly at the phrase level and only when it is composed of very complex descriptions laden with technical terms for which there are no suitable substitutes. Authors may recycle longer segments of text using standard scholarly conventions of quotation and attribution or via some other informal means that alerts readers as to the scope of the recycling, thereby ensuring transparency. The use of percent similarity scores as thresholds for acceptable amounts of reuse should be discouraged. Instead, editors should be given the flexibility to evaluate each instance of recycling by taking into account factors such as the technical nature of the recycled text and the language proficiency of the authors. This article is a response to the following commentary: http://researchintegrityjournal.biomedcentral.com/articles/10.1186/s41073-017 0025-z. PMID- 29451561 TI - What incentives increase data sharing in health and medical research? A systematic review. AB - Background: The foundation of health and medical research is data. Data sharing facilitates the progress of research and strengthens science. Data sharing in research is widely discussed in the literature; however, there are seemingly no evidence-based incentives that promote data sharing. Methods: A systematic review (registration: 10.17605/OSF.IO/6PZ5E) of the health and medical research literature was used to uncover any evidence-based incentives, with pre- and post empirical data that examined data sharing rates. We were also interested in quantifying and classifying the number of opinion pieces on the importance of incentives, the number observational studies that analysed data sharing rates and practices, and strategies aimed at increasing data sharing rates. Results: Only one incentive (using open data badges) has been tested in health and medical research that examined data sharing rates. The number of opinion pieces (n = 85) out-weighed the number of article-testing strategies (n = 76), and the number of observational studies exceeded them both (n = 106). Conclusions: Given that data is the foundation of evidence-based health and medical research, it is paradoxical that there is only one evidence-based incentive to promote data sharing. More well-designed studies are needed in order to increase the currently low rates of data sharing. PMID- 29451563 TI - A Highly Sensitive Non-Radioactive Activity Assay for AMP-Activated Protein Kinase (AMPK). AB - While many methods exist to quantitatively determine protein kinase activities, 32P-based radioactive assays remain the workhorse of many laboratories due to their high sensitivity, high signal to noise ratio, lack of interference by fluorescent and light-absorbing small molecules, and easy quantitation. Here, we demonstrate that the interaction between the yeast Rad53 Forkhead-associated (FHA) domain and a peptide optimized for phosphorylation by AMP-Activated Protein Kinase (AMPK), which has previously been exploited for the generation of intracellular phosphorylation sensors, can serve as a readout for a highly sensitive two-step AMPK AlphaScreen kinase assay with exceptional signal-to-noise ratio.

PMID- 29451566 TI - Rational fabrication of silver-coated AFM TERS tips with a high enhancement and long lifetime. AB - Tip-enhanced Raman spectroscopy (TERS), known as nanospectroscopy, has received increasing interest as it can provide nanometer spatial resolution and chemical fingerprint information of samples simultaneously. Since Ag tips are well accepted to show a higher TERS enhancement than that of gold tips, there is an urgent quest for Ag TERS tips with a high enhancement, long lifetime, and high reproducibility, especially for atomic force microscopy (AFM)-based TERS. Herein, we developed an electrodeposition method to fabricate Ag-coated AFM TERS tips in a highly controllable and reproducible way. We investigated the influence of the electrodeposition potential and time on the morphology and radius of the tip. The radii of Ag-coated AFM tips can be rationally controlled at a few to hundreds nanometers, which allows us to systematically study the dependence of the TERS enhancement on the tip radius. The Ag-coated AFM tips show the highest TERS enhancement under 632.8 nm laser excitation and a broad localized surface plasmon resonance (LSPR) response when coupled to a Au substrate. The tips exhibit a lifetime of 13 days, which is particularly important for applications that need a long measuring time. PMID- 29451565 TI - Reporting of sex and gender in randomized controlled trials in Canada: a cross sectional methods study. AB - Background: Accurate reporting on sex and gender in health research is integral to ensuring that health interventions are safe and effective. In Canada and internationally, governments, research organizations, journal editors, and health agencies have called for more inclusive research, provision of sex-disaggregated data, and the integration of sex and gender analysis throughout the research process. Sex and gender analysis is generally defined as an approach for considering how and why different subpopulations (e.g., of diverse genders, ages, and social locations) may experience health conditions and interventions in different or similar ways.The objective of this study was to assess the extent and nature of reporting about sex and/or gender, including whether sex and gender analysis (SGA) was carried out in a sample of Canadian randomized controlled trials (RCTs) with human participants. Methods: We searched MEDLINE from 01 January 2013 to 23 July 2014 using a validated filter for identification of RCTs, combined with terms related to Canada. Two reviewers screened the search results to identify the first 100 RCTs that were either identified in the trial publication as funded by a Canadian organization or which had a first or last author based in Canada. Data were independently extracted by two people from 10% of the RCTs during an initial training period; once agreement was reached on this sample, the remainder of the data extraction was completed by one person and verified by a second. Results: The search yielded 1433 records. We screened 256 records to identify 100 RCTs which met our eligibility criteria. The median sample size of the RCTs was 107 participants (range 12-6085). While 98% of studies described the demographic composition of their participants by sex, only 6% conducted a subgroup analysis across sex and 4% reported sex-disaggregated data. No article defined "sex" and/or "gender." No publication carried out a comprehensive sex and gender analysis. Conclusions: Findings highlight poor uptake of sex and gender considerations in the Canadian RCT context and underscore the need for better articulated guidance on sex and gender analysis to improve reporting of evidence, inform policy development, and guide future research. PMID- 29451567 TI - Stable, small, specific, low-valency quantum dots for single-molecule imaging. AB - We have developed a strategy for synthesizing immediately activable, water soluble, compact (~10-12 nm hydrodynamic diameter) quantum dots with a small number of stable and controllable conjugation handles for long distance delivery and subsequent biomolecule conjugation. Upon covalent conjugation with engineered monovalent streptavidin, the sample results in a population consisting of low valency quantum dots. Alternatively, we have synthesized quantum dots with a small number of biotin molecules that can self-assemble with engineered divalent streptavidin via high-affinity biotin-streptavidin interactions. Being compact, stable and highly specific against biotinylated proteins of interest, these low valency quantum dots are ideal for labeling and tracking single molecules on the cell surface with high spatiotemporal resolution for different biological systems and applications.

AB - A highly efficient sulfonylation of thiols has been achieved through the metal free NaI/TBHP-mediated cross-coupling of sulfonyl hydrazides and thiols at room temperature. This method provides a convenient and practical route to thiosulfonates in 84-99% yields (39 examples) with wide functional group compatibility. PMID- 29451570 TI - Insights into the formation mechanism of two-dimensional lead halide nanostructures. AB - We present a colloidal synthesis strategy for lead halide nanosheets with a thickness of far below 100 nm. Due to the layered structure and the synthesis parameters the crystals of PbI2 are initially composed of many polytypes. We propose a mechanism which gives insight into the chemical process of the PbI2 formation. Further, we found that the crystal structure changes with increasing reaction temperature or by performing the synthesis for longer time periods changing for the final 2H structure. In addition, we demonstrate a route to prepare nanosheets of lead bromide as well as lead chloride in a similar way. Lead halides can be used as a detector material for high-energy photons including gamma and X-rays. PMID- 29451571 TI - Sea spray aerosol chemical composition: elemental and molecular mimics for laboratory studies of heterogeneous and multiphase reactions. AB - Sea spray aerosol particles (SSA), formed through wave breaking at the ocean surface, contribute to natural aerosol particle concentrations in remote regions of Earth's atmosphere, and alter the direct and indirect effects of aerosol particles on Earth's radiation budget. In addition, sea spray aerosol serves as suspended surface area that can catalyze trace gas reactions. It has been shown repeatedly that sea spray aerosol is heavily enriched in organic material compared to the surface ocean. The selective enrichment of organic material complicates the selection of representative molecular mimics of SSA for laboratory or computational studies. In this review, we first provide a short introduction to SSA formation processes and discuss chemical transformations of SSA that occur in polluted coastal regions and remote pristine air. We then focus on existing literature of the chemical composition of nascent SSA generated in controlled laboratory experiments and field investigations. We combine the evidence on the chemical properties of nascent SSA with literature measurements of SSA water uptake to assess SSA molecular composition and liquid water content. Efforts to speciate SSA organic material into molecular classes and specific molecules have led to the identification of saccharides, alkanes, free fatty acids, anionic surfactants, dicarboxylic acids, amino acids, proteinaceous matter, and other large macromolecules. However to date, less than 25% of the organic mass of nascent SSA has been quantified at a molecular level. As discussed here, quantitative measurements of size resolved elemental ratios, combined with determinations of water uptake properties, provides unique insight on the concentration of ions within SSA as a function of particle size, pointing to a controlling role for relative humidity and the hygroscopicity of SSA organic material at small particle diameters. PMID- 29451572 TI - 3D printed scaffolds with gradient porosity based on a cellulose nanocrystal hydrogel. AB - 3-Dimensional (3D) printing provides a unique methodology for the customization of biomedical scaffolds with respect to size, shape, pore structure and pore orientation useful for tissue repair and regeneration. 3D printing was used to fabricate fully bio-based porous scaffolds of a double crosslinked interpenetrating polymer network (IPN) from a hydrogel ink of sodium alginate and gelatin (SA/G) reinforced with cellulose nanocrystals (CNCs). CNCs provided favorable rheological properties required for 3D printing. The 3D printed scaffolds were crosslinked sequentially via covalent and ionic reactions resulting in dimensionally stable hydrogel scaffolds with pore sizes of 80-2125 MUm and nanoscaled pore wall roughness (visible from scanning electron microscopy) favorable for cell interaction. The 2D wide angle X-ray scattering studies showed that the nanocrystals orient preferably in the printing direction; the degree of orientation varied between 61-76%. The 3D printing pathways were optimised successfully to achieve 3-dimensional scaffolds (Z axis up to 20 mm) with uniform as well as gradient pore structures. This study demonstrates the potential of 3D printing in developing bio-based scaffolds with controlled pore sizes, gradient pore structures and alignment of nanocrystals for optimal tissue regeneration. PMID- 29451568 TI - Upconversion in photodynamic therapy: plumbing the depths. AB - Photodynamic therapy (PDT) involves the combination of non-toxic dyes called photosensitizers (PS) and harmless visible light that interact with ambient oxygen to give reactive oxygen species (ROS) that can damage biomolecules and kill cells. PDT has mostly been developed as a cancer therapy but can also be used as an antimicrobial approach against localized infections. However even the longest wavelength used for exciting PS (in the 700 nm region) has relatively poor tissue penetration, and many PS are much better excited by blue and green light. Therefore upconversion nanoparticles (UCNPs) have been investigated in order to allow deeper-penetrating near-infrared light (980 nm or 810 nm) to be used for PDT. NaYF4 nanoparticles doped with Yb3+ and Er3+ or with Tm3+ and Er3+ have been attached to PS either by covalent conjugation, or by absorption to the coating or shell (used to render the UCNPs biocompatible). Forster resonance energy transfer to the PS then allows NIR light energy to be transduced into ROS leading to cell killing and tumor regression. Some studies have experimentally demonstrated the deep tissue advantage of UCNP-PDT. Recent advances have included dye-sensitized UCNPs and UCNPs coupled to PS, and other potentially synergistic drug molecules or techniques. A variety of bioimaging modalities have also been combined with upconversion PDT. Further studies are necessary to optimize the drug-delivery abilities of the UCNPs, improve the quantum yields, allow intravenous injection and tumor targeting, and ensure lack of toxicity at the required doses before potential clinical applications. PMID- 29451573 TI - Wavelength-tunable mid-infrared thermal emitters with a non-volatile phase changing material. AB - The ability to continuously tune the emission wavelength of mid-infrared thermal emitters while maintaining high peak emissivity remains a challenge. By incorporating the nonvolatile phase changing material Ge2Sb2Te5 (GST), two different kinds of wavelength-tunable mid-infrared thermal emitters based on simple layered structures (GST-Al bilayer and Cr-GST-Au trilayer) are demonstrated. Aiming at high peak emissivity at a tunable wavelength, an Al film and an ultrathin (~5 nm) top Cr film are adopted for these two structures, respectively. The gradual phase transition of GST provides a tunable peak wavelength between 7 MUm and 13 MUm while high peak emissivity (>0.75 and >0.63 for the GST-Al and Cr-GST-Au emitters, respectively) is maintained. This study shows the capability of controlling the thermal emission wavelength, the application of which may be extended to gas sensors, infrared imaging, solar thermophotovoltaics, and radiative coolers.

AB - In the last few decades, gold complexes have demonstrated huge potential for soft Lewis acid catalysis. Despite the intensive research on Au complexes and planar chiral metallacycles, enantiopure ferrocenylgold complexes have - surprisingly - not been reported until the studies presented in this article. Herein, we report the asymmetric synthesis of planar chiral ferrocenyl Au(i) complexes. These dinuclear species form helically chiral ten-membered (NCCCAu)2 rings stabilized by aurophilic interactions. In supramolecular solid state structures, linear, zigzag or helical Au(i) wires with regular AuAu separations were observed. The dissolved dinuclear entities could be oxidized by Au(i) to unique ferrocenyl Au(ii) complexes featuring short Au(ii)-Au(ii) bonds, while the ferrocene core remained intact. However, our initial studies revealed the issue of configurational lability of the ferrocenyl Au(ii) complexes in terms of the element of planar chirality in the presence of the gold source, (Me2S)AuCl. This was successfully addressed by a systematic study implementing permanent sigma donor ortho-protecting groups such as methyl and trimethylsilyl, which impede an epimerization event. Oxidation of the dinuclear Au(i) complexes was also accomplished by oxidative addition reactions with halogenated solvents, preferably CHCl3. Additional reactivity studies revealed that dinuclear Au(ii) dihalide complexes are also formed with reactive alkylhalides such as iodomethane, benzylbromide and benzyliodide. Interestingly, the whole spectral range of colors (violet, blue, green, yellow, and red) is covered by the title complexes depending on the Au oxidation state and the anionic ligands in the Au(ii) complexes. This appears to be quite unusual for ferrocenes, which typically adopt orange to red colors in a non-oxidized state.

AB - Multifunctional nano-biomaterials with the integration of diagnostic and therapeutic functions have shown great promise in improving the efficacy of cancer therapy. Herein, a new nanoplatform based on functionalized Cu3BiS3 nanoparticles (NPs) is fabricated for tumour-targeted combination phototherapy. The as-synthesized hydrophobic Cu3BiS3 NPs are modified with DSPE-PEG/DSPE-PEG NH2, followed by the conjugation of the photosensitizer chlorin e6 (Ce6) and the target ligand folic acid (FA). The introduced Ce6 can further form a chelate complex with Gd3+. The rationally designed Cu3BiS3-PEG-(Ce6-Gd3+)-FA NPs, which have high physiological stability and good biocompatibility, can specifically target FA-receptor over-expressed tumour cells. The Cu3BiS3-PEG-(Ce6-Gd3+)-FA NPs exhibit effective dual-modal CT and MR imaging in the xenografted HeLa tumours. Importantly, excellent in vivo anti-tumour effects have been achieved by synergistic photothermal/photodynamic therapy using the multifunctional NPs. We expect that this versatile nanoplatform will play a role in exploring precise cancer diagnosis and therapy. PMID- 29451576 TI - ortho-Chlorination of phenoxy 1,2-dioxetane yields superior chemiluminescent probes for in vitro and in vivo imaging. AB - A recent methodology, developed by our group, has enabled a dramatic improvement in the emissive nature of the excited species, formed during the chemiexcitation of dioxetanes under physiological conditions. This approach has resulted in the discovery of distinct phenoxy-dioxetane luminophores that produce a chemiluminescence signal via a direct-mode of emission. Here, we show a significant pKa effect of our new phenoxy-dioxetanes on their chemiexcitation and on their ability to serve as chemiluminescent turn-ON probes for biological applications. Using an appropriate phenoxy-dioxetane probe with a direct-mode of emission, we were able to image beta-galactosidase activity, in cancer cells and in tumor-bearing mice. To the best of our knowledge, this is the first example to demonstrate in vitro and in vivo endogenous enzymatic chemiluminescence images obtained by a single-component phenoxy-dioxetane probe. We anticipate that our strategy, for the design and synthesis of such distinct luminophores, will assist in providing new effective turn-ON probes for non-invasive intravital chemiluminescence imaging techniques. PMID- 29451577 TI - An upconversion nanoplatform with extracellular pH-driven tumor-targeting ability for improved photodynamic therapy. AB - Upconversion nanoparticles (UCNPs) are widely utilized for photodynamic therapy (PDT) due to their specific upconverting luminescence that utilizes near infrared (NIR) light to excite photosensitizers (PSs) for PDT. The efficiency of UCNP based PDT will be improved if the cancer-targeting property of nanomedicine is enhanced. Herein, we employed the pH low insertion peptide (pHLIP), a cancer targeting moiety, to functionalize an 808 nm excited UCNP-based nanoplatform that has a minimized over-heating effect to perform PDT. pHLIP can bring cargo specifically into cancer cells under an acidic environment, realizing the effective active-targeting abilities to cancer cells or tumor due to acidosis. The pHLIP-functionalized nanoplatform was assembled and well characterized. The nanoplatform shows an efficient NIR-irradiated PDT effect in cancer cells, especially under a slightly acidic condition that mimics the tumor microenvironment, and this effectiveness is attributed to the targeting properties of pHLIP to cancer cells under acidic conditions that favor the entry of the nanoplatform. Furthermore, the pHLIP-functionalized nanoplatform shows a favorable safety profile in mice with a high maximum tolerated dose (MTD), which may broaden the availability of administration in vivo. The efficient in vivo antitumor activity is achieved through intratumor injection of the nanoplatform followed by NIR irradiation on the breast tumor. The nanoparticles are largely accumulated in the tumor site, revealing the excellent tumor-targeting properties of the pHLIP-functionalized nanoplatform, which ensures efficient PDT in vivo. Moreover, the nanoparticles have a long retention time in the bloodstream, indicating their stability in vivo. Overall, we provide an example of a UCNP based nanosystem with tumor-targeting properties to perform efficient PDT both in vitro and in vivo.

AB - We have strategically incorporated three different fluorophores at tren to construct a multi-energy donor/acceptor "smart" probe L. This probe operates by using three-dimensional scales (response time, wavelength and fluorescence intensity) which allows for the selective recognition and discrimination of the Cu2+, Hg2+, Fe3+ and F- ions.

AB - 2,6-Bis(2-quinolyl)-4(1H)-pyridone 1, a novel quinoline analogue of the well known ligand 2-terpyridone, shows unusual fluorescence with a large Stokes shift and low energy emission. Pyridine-pyridone tautomerism is investigated by NMR and theoretical methods and indicates that the low energy emission is from the pyridine form. 1 reacts with Ag(i) salts to give a double helical Ag2N6 core showing a BLUE shift in fluorescence with respect to the free ligand, which has been characterised experimentally and theoretically as involving an unusual mixed MLCT/ILCT excited state and emission from a singlet state. PMID- 29451580 TI - Covalent organic nanosheets for effective charge transport layers in planar-type perovskite solar cells. AB - Herein, solvent-treated bandgap-tunable covalent organic nanosheets (CONs) were prepared via the Stille cross-coupling reaction. These materials are considered useful as interlayers in photovoltaic devices upon the alignment of energy levels between other components. Among various types of solar cells, according to the organic-interlayer study, inverted planar perovskite solar cells (PSCs) are mostly demanded to effectively transport and collect charge carriers due to their high performance. At first, the C-V analysis proved the energy levels of the frontier orbitals for CON-10 and CON-16 nanosheets; this verified the suitability of these nanosheets as hole transport layers (HTLs) with the PEDOT:PSS upon casting both films from DMSO. It became evident, however, that the hole transport property of the PEDOT:PSS on the CON-16 layer was unfavorable with the increasing UPS-proven hole injection barrier. In addition, both CONs induced a rough surface morphology; however, CON-10 showed a relatively smooth surface as compared to CON 16 based on the Scanning electron microscopy (SEM) and Atomic force microscopy (AFM) profiles; furthermore, their surface properties influenced both the PEDOT:PSS layers and the perovskite layers. Especially, the XRD profiles presented an enhanced crystallinity of the perovskite layers with CON-10. All these aspects indicate that CON-10 is a more effective HTL material, and several versions of perovskite solar cells (PSCs) have been fabricated with/without CON 10 and CON-16 together with the PEDOT:PSS to determine the more-HTL-suitable CON. As a result, the power conversion efficiencies (PCEs) of the optimized devices with CON-10 exhibited a value of 10.2%, which represented a 1% increase over those of the reference devices without the CONs and was 4% higher than that of the CON-16 devices. Moreover, the devices with CON-10 were further optimized with TiOx using Al electrodes, leading to a PCE increase of these devices that became slightly higher than the PCEs of the device with CON-10 and without TiOx. This tendency was supported by photoluminescence (PL) spectroscopy, photocurrent density (Jph), and space-charge-limited current (SCLC) mobility results. PMID- 29451581 TI - Tautomerism and electronic spectroscopy of protonated 1- and 2-aminonaphthalene. AB - Experimental and theoretical investigations of the excited states of protonated 1 and 2-aminonaphthalene are presented. The electronic spectra are obtained by laser induced photofragmentation of the ions captured in a cold ion trap. Using ab initio calculations, the electronic spectra can be assigned to different tautomers which have the proton on the amino group or on the naphthalene moiety. It is shown that the tautomer distribution can be varied by changing the electrospray source conditions, favoring either the most stable form in solution (amino protonation) or that in the gas phase (aromatic ring protonation). Calculations for larger amino-polyaromatics predict that these systems should behave as "proton sponges" i.e. have a proton affinity larger than 11 eV. PMID- 29451582 TI - Adsorptive removal of organic dyes from aqueous solution by a Zr-based metal organic framework: effects of Ce(iii) doping. AB - Herein, we report the synthesis and characterization of Ce(iii)-doped UiO-66 nanocrystals, revealing their potential to efficiently remove organic dyes such as methylene blue (MB), methyl orange (MO), Congo red (CR), and acid chrome blue K (AC) from aqueous solutions. Specifically, the room-temperature adsorption capacities of Ce(iii)-doped UiO-66 equaled 145.3 (MB), 639.6 (MO), and 826.7 (CR) mg g-1, exceeding those reported for pristine UiO-66 by 490, 270, and 70%, respectively. The above behavior was rationalized based on zeta potential and adsorption isotherm investigations, which revealed that Ce(iii) doping increases the number of adsorption sites and promotes pi-pi interactions between the adsorbent and the adsorbate, thus improving the adsorption capacity for cationic and anionic dyes and overriding the effect of electrostatic interactions. The obtained results shed light on the mechanism of organic dye adsorption on metal organic frameworks, additionally revealing that the synergetic interplay of electrostatic, pi-pi, and hydrophobic interactions results in the operation of two distinct adsorption regimes depending on adsorbate concentration.

PMID- 29451584 TI - Exposure to violence: associations with psychiatric disorders in Brazilian youth. AB - OBJECTIVE: The effects of exposure to violent events in adolescence have not been sufficiently studied in middle-income countries such as Brazil. The aims of this study are to investigate the prevalence of psychiatric disorders among 12-year olds in two neighborhoods with different socioeconomic status (SES) levels in Sao Paulo and to examine the influence of previous violent events and SES on the prevalence of psychiatric disorders. METHODS: Students from nine public schools in two neighborhoods of Sao Paulo were recruited. Students and parents answered questions about demographic characteristics, SES, urbanicity and violent experiences. All participants completed the Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS) to obtain DSM-IV diagnoses. The data were analyzed using weighted logistic regression with neighborhood stratification after adjusting for neighborhood characteristics, gender, SES and previous traumatic events. RESULTS: The sample included 180 individuals, of whom 61.3% were from low SES and 39.3% had experienced a traumatic event. The weighted prevalence of psychiatric disorders was 21.7%. Having experienced a traumatic event and having low SES were associated with having an internalizing (adjusted OR = 5.46; 2.17-13.74) or externalizing disorder (adjusted OR = 4.33; 1.85 10.15). CONCLUSIONS: Investment in reducing SES inequalities and preventing violent events during childhood may improve the mental health of youths from low SES backgrounds. PMID- 29451585 TI - Psychoactive substance abuse and dependence and its association with anxiety disorders: a population-based study of young adults in Brazil. AB - OBJECTIVE: To evaluate the association between abuse of and dependence on different psychoactive substances and the presence of anxiety disorders in a sample of young adults from a city in southern Brazil. METHODS: Between 2007 and 2009, we carried out a cross-sectional, population-based study of individuals aged 18-24 years who lived in Pelotas, a city in southern Brazil. We evaluated anxiety disorders using the Mini International Neuropsychiatric Interview 5.0 (MINI), and use of psychoactive substances with the Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST 2.0/0MS). We used Fisher's exact test for univariate analysis, and Poisson regression models with robust variance for multivariable analysis. RESULTS: The sample consisted of 1,560 young adults. The overall prevalence of abuse/dependence was 26.9% for alcohol, 24.9% for tobacco, and 7.3% for illicit substances. Individuals with agoraphobia had a 32% higher prevalence of tobacco abuse/dependence (prevalence ratio [PR] = 1.32 [95%CI 1.01-1.74]). Individuals with posttraumatic stress disorder (PTSD) or generalized anxiety disorder (GAD) had a 2.41-fold (95%CI 1.22-4.77) and 1.76 fold (95%CI 1.00-3.11) higher prevalence of illicit substance abuse/dependence, respectively. CONCLUSION: In this population-based sample, we found associations between GAD, PTSD, and increased prevalence of illicit substance abuse/dependence. In addition, individuals with agoraphobia seem to have increased tobacco abuse/dependence. PMID- 29451586 TI - Virtual reality exposure therapy for fear of driving: analysis of clinical characteristics, physiological response, and sense of presence. AB - OBJECTIVE: To investigate the reactions of women with driving phobia to a therapeutic program of scheduled virtual reality exposure treatment (VRET) sessions. METHODS: The study intervention consisted of a computer game with car driving scenarios that included several traffic situations. We investigated the participants' sense of presence, subjective distress, and physiological responses during eight virtual-reality exposures. We also evaluated clinical characteristics, driving cognitions, and quality of life in the participants. RESULTS: Thirteen women were selected. Eight were able to complete the protocol. After VRET, there was a decrease in the frequency of distorted thoughts and state anxiety scores, as well as a slight improvement in quality of life. Subjective discomfort scores, heart rate variation, and sense of presence scores confirmed that there was sense of presence in the virtual reality environment. CONCLUSION: All patients showed some degree of improvement and demonstrated different levels of anxiety in subsequent in vivo driving experiences. Our findings suggest that VRET could be used to facilitate in vivo exposure, because it can induce presence/immersion and reduce anxiety in patients with specific phobia. Furthermore, VRET is not associated with any type of risk. PMID- 29451587 TI - Diagnosing dementia in lower educated older persons: validation of a Brazilian Portuguese version of the Rowland Universal Dementia Assessment Scale (RUDAS). AB - OBJECTIVE: To validate the Rowland Universal Dementia Assessment Scale for use in Brazil (RUDAS-BR). METHODS: We first completed an English-Brazilian Portuguese translation and back-translation of the RUDAS. A total of 135 subjects over 60 years of age were included: 65 cognitively healthy and 70 with Alzheimer's disease (AD) according to the DSM-IV and Neurological and Communicative Disorders and Stroke/Alzheimer's Disease and Related Disorders Association (NINCDS-ADRDA) criteria. All participants completed an interview and were screened for depression. The receiver operating characteristic curves of the RUDAS were compared with those of the Mini Mental State Examination (MMSE) regarding the sensitivity and specificity of cutoffs, taking education into consideration. RESULTS: The areas under the curve were similar for the RUDAS-BR (0.87 [95%CI 0.82-0.93]) and the MMSE (0.84 [95%CI 0.7-0.90]). RUDAS-BR scores < 23 indicated dementia, with sensitivity of 81.5% and specificity of 76.1%. MMSE < 24 indicated dementia, with sensitivity of 72.3% and specificity of 78.9%. The cutoff score was influenced by years of education on the MMSE, but not on the RUDAS-BR. CONCLUSIONS: The RUDAS-BR is as accurate as the MMSE in screening for dementia. RUDAS-BR scores were not influenced by education. The RUDAS-BR may improve the cognitive assessment of older persons who are illiterate or of lower educational attainment. PMID- 29451588 TI - Religiosity, depression, and quality of life in bipolar disorder: a two-year prospective study. AB - OBJECTIVE: Few quantitative studies have examined the effect of religious involvement on the course of bipolar disorder (BD). We investigated the effects of religious activity and coping behaviors on the course of depression, mania, and quality of life (QoL) in patients with BD. METHODS: Two-year longitudinal study of 168 outpatients with BD. Linear regression was used to examine associations between religious predictors and outcome variables (manic symptoms, depression, QoL), controlling for sociodemographic variables. RESULTS: Among the 158 patients reassessed after 2 years, positive religious coping at T1 predicted better QoL across all four domains: physical (beta = 10.2, 95%CI 4.2 to 16.1), mental (beta = 13.4, 95%CI 7.1 to 19.7), social (beta = 10.5, 95%CI 3.6 to 17.33), and environmental (beta = 11.1, 95%CI 6.2 to 16.1) at T2. Negative religious coping at T1 predicted worse mental (beta = -28.1, 95%CI -52.06 to 4.2) and environmental (beta = -20.4, 95%CI -39.3 to -1.6) QoL. Intrinsic religiosity at T1 predicted better environmental QoL (beta = 9.56, 95%CI 2.76 to 16.36) at T2. Negative religious coping at T1 predicted manic symptoms (beta = 4.1) at T2. CONCLUSION: Religiosity/spirituality (R/S) may influence the QoL of patients with BD over time, even among euthymic patients. Targeting R/S (especially positive and negative religious coping) in psychosocial interventions may enhance the quality of recovery in patients with BD. PMID- 29451589 TI - Active Brazilian crack cocaine users: nutritional, anthropometric, and drug use profiles. AB - OBJECTIVE: To evaluate the nutritional status of crack users and to analyze its correlation with drug use profiles. METHODS: Cross-sectional study with 108 crack users. Anthropometric data were assessed through body mass index (BMI) and bioimpedance (BIA) measurements. A blood test to analyze hematocrit, hemoglobin, glucose, and lipid profiles was also performed. Crack use was determined through a standardized interview. RESULTS: Based on BMI and BIA, most individuals were eutrophic (about 70%). Regarding hematological parameters, we found that hemoglobin and hematocrit levels were below normal for 32.4 and 30.6% of patients, respectively. Considering normal parameters, a large part of the sample (60.2%) had low levels of HDL cholesterol and high levels of triglycerides (38%). There were no significant correlations between drug profile and nutritional variables. CONCLUSION: This is a pioneering study that examines the nutritional status of crack users. Our results showed that most crack users present normal anthropometric findings and the prevalence of underweight is low. However, blood analysis showed changes and a specific type of malnutrition. PMID- 29451590 TI - By the book: ADHD prevalence in medical students varies with analogous methods of addressing DSM items. AB - OBJECTIVE: The marked increase in the prevalence of attention deficit/hyperactivity disorder (ADHD) among university students gives rise to questions about how best to diagnose in this setting. The aim of the present study was to calculate ADHD prevalence in a large non-clinical sample of medical students using a stepwise design and to determine whether ADHD diagnosis varies if interviewees use additional probing procedures to obtain examples of positive DSM items. METHODS: A total of 726 students were screened with the Adult Self Report Scale (ASRS) and invited for an interview with the Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS) adapted for adults. RESULTS: The ASRS was positive for 247 students (37%), although only 83 (7.9%) received an ADHD diagnosis. ASRS sensitivity and specificity rates were 0.97 and 0.40, respectively. Probing procedures were used with a subgroup of 226 students, which decreased the number of ADHD diagnoses to 12 (4.5%). CONCLUSION: Probing for an individual's real-life examples during the K-SADS interview almost halved ADHD prevalence rate based on the ASRS and K-SADS, which rendered the rate consistent with that typically reported for young adults. In reclassified cases, although examples of inattention did not match the corresponding DSM item, they often referred to another DSM inattention item. PMID- 29451591 TI - Impact of aggressive periodontitis and chronic periodontitis on oral health related quality of life. AB - The purpose of this cross-sectional study was to investigate the effect of different forms of periodontal diseases on Oral Health-Related Quality of Life (OHRQoL). Fifty-two patients with Aggressive Periodontitis (AP) or Chronic Periodontitis (CP) were included: nine patients with Localized Aggressive Periodontitis (LAP), thirty-three patients with Generalized Aggressive Periodontitis (GAP) and ten patients with Generalized Chronic Periodontitis (GCP). Oral Health Impact Profile questionnaires (OHIP-14) were distributed after a clinical examination that measured the following periodontal parameters: tooth loss, bleeding on probing (BoP), probing depth (PD), gingival recession (REC) and clinical attachment level (CAL). The global OHIP-14 score means were 10.6 for LAP, 16.5 for GAP, and 17.5 for GCP. A statistically significant difference (p < 0.01) was observed between the LAP group and the other two groups. There was significantly less bleeding and recession in the LAP group than in the patients with the generalized forms of periodontitis. LAP, GAP and GCP have an impact on patient quality of life when measured using the OHIP-14. Patients with GAP and GCP had poorer OHRQoL than LAP patients. PMID- 29451592 TI - Prevalence of Streptococcus agalactiae colonization in pregnant women from the 18th Health Region of Parana State. AB - Introduction The aim of this study was to determine the prevalence of GBS colonization in pregnant women in a public health service. Methods A study of 496 pregnant women at 35-37 gestational weeks was conducted from September 2011 to March 2014 in 21 municipalities of the 18th Health Region of Parana State. Vaginal and anorectal samples of each woman were plated on sheep blood agar, and in HPTH and Todd-Hewitt enrichment broths. Results Of the 496 pregnant women, 141 (28.4%) were positive for GBS based on the combination of the three culture media with vaginal and anorectal samples. The prevalence was 23.7% for vaginal samples and 21.9% for anorectal ones. Among the variables analyzed in this study, only urinary infection was a significant factor (0.026) associated with GBS colonization in women. Conclusions Based on these results, health units should performs universal screening of pregnant women and hospitals should provide adequate prophylaxis, when indicated.

PMID- 29451594 TI - Nontuberculous mycobacteria in milk from positive cows in the intradermal comparative cervical tuberculin test: implications for human tuberculosis infections. AB - Although the tuberculin test represents the main in vivo diagnostic method used in the control and eradication of bovine tuberculosis, few studies have focused on the identification of mycobacteria in the milk from cows positive to the tuberculin test. The aim of this study was to identify Mycobacterium species in milk samples from cows positive to the comparative intradermal test. Milk samples from 142 cows positive to the comparative intradermal test carried out in 4,766 animals were aseptically collected, cultivated on Lowenstein-Jensen and Stonebrink media and incubated for up to 90 days. Colonies compatible with mycobacteria were stained by Ziehl-Neelsen to detect acid-fast bacilli, while to confirm the Mycobacterium genus, conventional PCR was performed. Fourteen mycobacterial strains were isolated from 12 cows (8.4%). The hsp65 gene sequencing identified M. engbaekii (n=5), M. arupense (n=4), M. nonchromogenicum (n=3), and M. heraklionense (n=2) species belong to the Mycobacterium terrae complex. Despite the absence of M. tuberculosis complex species in the milk samples, identification of these mycobacteria highlights the risk of pathogen transmission from bovines to humans throughout milk or dairy products, since many of mycobacterial species described here have been reported in pulmonary and extrapulmonary diseases both in immunocompetent and immunocompromised people. PMID- 29451595 TI - Evaluation of molluscicidal activity of three mangrove species (Avicennia schaueriana, Laguncularia racemosa and Rhizophora mangle) and their effects on the bioactivity of Biomphalaria glabrata Say, 1818. AB - Schistosomiasis is a disease of global extent reaching populations in social vulnerability. One of the control measures of this parasitosis is the use of molluscicidal substances that can fight snails of the genus Biomphalaria, intermediate hosts of Schistosoma mansoni. The aim of this work was to study the toxic activity of three mangrove species (Avicennia schaueriana Stapf. & Leech, ex Moldenke, 1939, Laguncularia racemosa (L.) CF Gaertn, 1807 and Rhizophora mangle L. 1753) on the biological activities of snails Biomphalaria glabrata. Hydroalcoholic extracts were prepared from the stem and leaves of each of the three plant species to which mollusks were exposed. The phytochemical analysis of plants showed the presence of important metabolites in the leaves and stems of L. racemosa and R. mangle, such as tannins and saponins, but the absence of these metabolites in A. schaueriana. Leaf and stem extracts of the three plant species showed low molluscicidal activity, not reaching the standards determined by the World Health Organization (WHO, 1983). L. racemosa and R. mangle has interfered with motility, feeding and oviposition of snails, unlike the extracts of A. schaueriana, which had no effect on these activities. PMID- 29451596 TI - Histopathological characteristics of cutaneous lesions caused by Leishmania Viannia panamensis in Panama. AB - Cutaneous leishmaniasis (CL) is an endemic disease in the Republic of Panama, caused by Leishmania (Viannia) parasites, whose most common clinical manifestation is the presence of ulcerated lesions on the skin. These lesions usually present a chronic inflammatory reaction, sometimes granulomatous, with the presence of lymphocytes, plasma cells and macrophages. This study describes the histopathological characteristics found in the skin lesions of patients with CL caused by Leishmania (V.) panamensis in Panama. We analyzed 49 skin biopsy samples from patients with clinical suspicion of CL, by molecular tests (PCR for subgenus Viannia and HSP-70) and by Hematoxylin-Eosin staining. Samples were characterized at the species level by PCR-HSP-70/RFLP. From the 49 samples studied, 46 (94%) were positive by PCR and were characterized as Leishmania (V.) panamensis. Of these, 48% were positive by Hematoxylin-Eosin staining with alterations being observed both, in the epidermis (85%) and in the dermis (100%) of skin biopsies. The inflammatory infiltrate was characterized according to histopathological patterns: lymphohistiocytic (50%), lymphoplasmacytic (61%) and granulomatous (46%) infiltration, being the combination of these patterns frequently found. The predominant histopathological characteristics observed in CL lesions caused by L. (V.) panamensis in Panama were: an intense inflammatory reaction in the dermis with a combination of lymphohistiocytic, lymphoplasmacytic and granulomatous presentation patterns and the presence of ulcers, acanthosis, exocytosis and spongiosis in the epidermis. PMID- 29451597 TI - Achatina fulica infected by Angiostrongylus cantonensis on beaches, in the west zone of Rio de Janeiro, Brazil. AB - Angiostrongylus cantonensis is considered the main etiological agent of eosinophilic meningitis in humans. At present, this zoonosis is considered an emerging disease mainly in the Americas. The aim of this study was to determine the prevalence of Achatina fulica infected by Angiostrongylus cantonensis in restinga areas along beaches in the west zone of Rio de Janeiro city, Brazil. The study areas included the following beaches: Barra da Tijuca, Recreio dos Bandeirantes, Reserva, Prainha and Grumari. Ninety specimens of Achatina fulica were collected. Positive molluscs were found only in Barra da Tijuca. Infection prevalence was 5.5%. The presence of this parasite in the beachfront areas, in the west zone of Rio de Janeiro city demonstrates the potential risk of infection for visitors and the expansion of this helminth in the State of Rio de Janeiro. PMID- 29451598 TI - Performance of cryptococcal antigen lateral flow assay in serum, cerebrospinal fluid, whole blood, and urine in HIV-infected patients with culture-proven cryptococcal meningitis admitted at a Brazilian referral center. AB - Cryptococcal meningitis is the most common cause of opportunistic meningitis in HIV-infected patients in Brazil and causes unacceptable high mortality rates. In this study, HIV-infected patients with a first episode of culture-proven cryptococcal meningitis in cerebrospinal fluid (CSF) were prospectively included in order to evaluate sensitivity of cryptococcal antigen (CrAg) lateral flow assay (LFA) in serum, CSF, whole blood (fingerstick), and fresh urine. In addition, HIV-infected patients with other neurological confirmed diseases were included in order to evaluate the specificity of CrAg LFA in serum. Twenty patients with cryptococcal meningitis were included and in 19 of them, CrAg LFA in CSF, serum, and whole blood were positive (95% sensitivity). In 18 patients, India ink test was positive in CSF (90% sensitivity), and in 16 cases, CrAg LFA was positive in urine (80% sensitivity). Thirty-six HIV-infected patients with other neurological diseases had negative results of CrAg LFA in serum (100% specificity). In conclusion, CrAg LFA in serum, CSF, and whole blood showed high sensitivity and specificity. Whole blood CrAg LFA seems to be a good and reliable strategy to improve AIDS-related cryptococcal meningitis diagnosis in Brazil.

AB - Leishmaniasis is a worldwide tropical infectious disease caused by different species of intracellular protozoa parasites of the genus Leishmania . Herein, we report a 78-year-old man with unusual diffuse cutaneous leishmaniasis (DCL) who had a history of opium abuse and chronic obstructive pulmonary disease (COPD). He had multiple papular, crusted and severely ulcerated lesions extended to his arm and chest. Direct smears and skin punch biopsy of the lesions were suggestive of leishmaniasis. Parasite DNA was amplified from ulcers, and identified as Leishmania major by PCR-RFLP, confirmed by sequencing analyses. The aim of the current study was to bring to attention this atypical form of disease in CL endemic countries. Thus, this is the first case of DCL in an opium abuser with COPD due to L. major in Northeastern Iran indicating that atypical and extensive forms of CL (DCL) owing to L. major are increasing in Iran.

AB - This clinical case presents a patient with a raised and ulcerative lesion with erythematous edges in the mouth, on the lower lip that was unsuccessfully treated as herpes labialis. Clinical data and laboratory tests (Montenegro skin test, indirect immunofluorescence, direct parasite search and polymerase chain reaction) led to the diagnosis of American tegumentary leishmaniasis caused by Leishmania (Viannia) sp. Treatment with pentavalent antimonial (Glucantime(r)) for 120 days was not effective and administration of amphotericin B for 30 days resulted in wound healing. Glucantime(r) treatment protocol was longer than the recommended by the Brazilian Ministry of Health in the handbook of mucosal leishmaniasis. This suggests that amphotericin B should have been administered earlier, preventing the psychological and social problems faced by the patient. This study reports a rare clinical case of primary mucosal leishmaniasis on the lip that had a delayed diagnosis, highlighting the precariousness in the management of disease and showing that, despite the importance of leishmaniasis in Brazil, it is still neglected by health professionals.

AB - The genus Corynebacterium includes species of great importance in medical, veterinary and biotechnological fields. The genus-specific families (PLfams) from PATRIC have been used to observe conserved proteins associated to all species. Our results showed a large number of conserved proteins that are associated with the cellular division process. Was not observe in our results other proteins like FtsA and ZapA that interact with FtsZ. Our findings point that SepF overlaps the function of this proteins explored by molecular docking, protein-protein interaction and sequence analysis. Transcriptomic analysis showed that these two (Sepf and FtsZ) proteins can be expressed in different conditions together. The work presents novelties on molecules participating in the cell division event, from the interaction of FtsZ and SepF, as new therapeutic targets.

AB - The 1,2-naphthoquinone compound was previously considered active against solid tumors. Moreover, glycosidase inhibitors such as 1,2,3-1H triazoles has been pointed out as efficient compounds in anticancer activity studies. Thus, a series of eleven 1,2-naphthoquinones tethered in C2 to 1,2,3-1H-triazoles 9a-k were designed, synthesized and their cytotoxic activity evaluated using HCT-116 (colon adenocarcinoma), MCF-7 (breast adenocarcinoma) and RPE (human nontumor cell line from retinal epithelium). The chemical synthesis was performed from C-3 allylation of lawsone followed by iodocyclization with subsequent nucleophilic displacement with sodium azide and, finally, the 1,3-dipolar cycloaddition catalyzed by Cu(I) with terminal alkynes led to the formation of 1H-1,2,3-Triazol 1-ylmethyl-2,3-dihydronaphtho[1,2-b]furan-4,5-diones in good yields. Compounds containing aromatic group linked to 1,2,3-triazole ring (9c, 9d, 9e, 9i) presented superior cytotoxic activity against cancer cell lines with IC50 in the range of 0.74 to 4.4 uM indicating that the presence of aromatic rings substituents in the 1,2,3-1H-triazole moiety is probably responsible for the improved cytotoxic activity. PMID- 29451603 TI - From Medicinal Chemistry to Human Health: Current Approaches to Drug Discovery for Cancer and Neglected Tropical Diseases. AB - Scientific and technological breakthroughs have compelled the current players in drug discovery to increasingly incorporate knowledge-based approaches. This evolving paradigm, which has its roots attached to the recent advances in medicinal chemistry, molecular and structural biology, has unprecedentedly demanded the development of up-to-date computational approaches, such as bio- and chemo-informatics. These tools have been pivotal to catalyzing the ever increasing amount of data generated by the molecular sciences, and to converting the data into insightful guidelines for use in the research pipeline. As a result, ligand- and structure-based drug design have emerged as key pathways to address the pharmaceutical industry's striking demands for innovation. These approaches depend on a keen integration of experimental and molecular modeling methods to surmount the main challenges faced by drug candidates - in vivo efficacy, pharmacodynamics, metabolism, pharmacokinetics and safety. To that end, the Laboratorio de Quimica Medicinal e Computacional (LQMC) of the Universidade de Sao Paulo has developed forefront research on highly prevalent and life threatening neglected tropical diseases and cancer. By taking part in global initiatives for pharmaceutical innovation, the laboratory has contributed to the advance of these critical therapeutic areas through the use of cutting-edge strategies in medicinal chemistry.

PMID- 29451605 TI - Evaluation of the frequency of Candida spp. in hospitalized and non-hospitalized subjects. AB - The aim of this study was to evaluate the frequency of Candida species between a non-hospitalized and a hospitalized population. For this purpose, samples of saliva were sampled through sterile swabs, moistened in peptone water and rubbed in the oral cavity of 140 individuals, from which, 70 were hospitalized patients from the Medical Clinic of a Teaching Hospital and the other 70 were non hospitalized subjects. All saliva samples were plated in Sabouraud Dextrose agar added with Chloramphenicol and incubated at 36 degrees C for 48 hours. The morphology identification was performed through macroscopic and microscopic characterization, the CHROMagar Candida medium and the VITEK(r) system Yeast Biochemical Card (bio Merieux SA, France). The results showed a colonization of Candida spp. in 85.7% the hospitalized individuals, where the species found were C. albicans (60%), C. tropicalis (23.4%), C. krusei (3.3%) and Candida spp. (13.3%). In the non-hospitalized individuals the colonization by Candida spp was 47.1%, and the species found were: C. albicans (45.5%), C.krusei (9.1%), C. guilliermondii (9.1% %), C. tropicalis (3.0%), C. famata (3.0%) and Candida spp. (30.3%). In spite of their presence in oral cavity in both groups, Candida spp. was more frequently isolated in hospitalized individuals, who were 6.73 times more likely to have this fungus in the oral cavity and were 3.88 times more likely to have Candida albicans. PMID- 29451606 TI - Can climate and soil conditions change the morpho-anatomy among individuals from different localities? A case study in Aldama grandiflora (Asteraceae). AB - Vegetative aerial organs are considerably more exposed to environmental conditions and can reflect the specific adaptations of plants to their local environment. Aldama grandiflora species are known to be widely distributed in Brazil; therefore, individuals from different populations of this species are thought to be exposed to different abiotic and biotic conditions. Several anatomical studies conducted on Brazilian Aldama species have mainly focused on the qualitative anatomical characters or traits of these species, but not on their quantitative traits. In this study, we evaluated whether climate and soil conditions can change the morphometry among individuals of A. grandiflora collected from six sites in the Goias State, Brazil, by assessing their anatomical characters. Further, soil sampling was performed, and climate data were collected from all the six sites. The analysis indicated few statistical differences among the populations evaluated, showing that A. grandiflora presented consistent leaf and stem anatomical characteristics. The small morpho anatomical differences found among individuals of the different populations evaluated, reflected the soil conditions in which these populations were grown. Therefore, environmental factors have a significant influence on the morpho anatomy of Aldama grandiflora. PMID- 29451607 TI - Decolorization of textile industry wastewater in solid state fermentation with Peach-Palm (Bactris gasipaes) residue. AB - In this work we have assessed the decolorization of textile effluents throughout their treatment in a solid-state fermentation (SSF) system. SSF assays were conducted with peach-palm (Bactris gasipaes) residue using the white rot fungus Ganoderma lucidum EF 31. The influence of the dye concentration and of the amounts of peach-palm residue and liquid phase on both the discoloration efficiency and enzyme production was studied. According to our results, independently of experimental conditions employed, laccase was the main ligninolytic enzyme produced by G. lucidum. The highest laccase activity was obtained at very low effluent concentrations, suggesting the existence of an inhibitory effect of higher concentrations on fungal metabolism. The highest percentage of color removal was reached when 10 grams of peach palm residue was moistened with 60 mL of the final effluent. In control tests carried out with the synthetic dye Remazol Brilliant Blue R (RBBR) decolorization efficiencies about 20% higher than that achieved with the industrial effluent were achieved. The adsorption of RBBR on peach-palm residue was also investigated. Equilibrium tests showed that the adsorption of this dye followed both Langmuir and Freundlich isotherms. Hence, our experimental results indicate that peach-palm residue is suitable substrate for both laccase production and color removal in industrial effluents.

AB - We analyzed floristic variations in fern's metacommunity at the local scale and their relationship with abiotic factors in an Atlantic Forest remnant of northeastern Brazil. Floristic and environmental variations were accessed on ten plots of 10 * 20 m. We performed cluster analyses, based on Bray-Curtis dissimilarity index to establish the floristic relationship. The influence of abiotic factors: luminosity, temperature, relative air humidity and relative soil moisture was evaluated from a redundancy analysis. We found 24 species belonging to 20 genera and 12 families. The fern's flora showed high floristic heterogeneity (>75% for most of the plot's associations). The fern's metacommunity was structured along an abiotic gradient modulated by temperature, luminosity, and relative soil moisture.

AB - OBJECTIVE: to assess the coverage, completeness and reliability of data on live births in public maternity wards in Sao Paulo, Brazil. METHODS: data recorded in the Information System on Live Births (Sinasc) were compared with data collected in a field study (gold standard) during three months in 2011 in four maternity wards in hospital from the SUS network; kappa coefficient was calculated to assess agreement. RESULTS: 5,785 birth records were analyzed; Sinasc coverage was 99.8% and completeness was 96.2%; kappa values showed excellent and good agreement for maternal age (0.99), type of pregnancy, sex and newborn sex and birth weight (0.98), type of delivery (0.97), 1 minute (0.96) and 5th (0.95) minutes, previous live births (0.87) and education level (0.62); regular agreement for prenatal care visits (0.60) and gestational age (0.56); and weak agreement for previous stillbirths (0.09). CONCLUSION: in the assessed hospitals, Sinasc presented high coverage, completeness and reliability. PMID- 29451611 TI - Factors associated with HIV co-infection in cases of acquired syphilis reported in a Reference Center for Sexually Transmitted Diseases and AIDS in the municipality of Sao Paulo, Brazil, 2014. AB - OBJECTIVE: to describe sociodemographic and behavioral characteristics and to identify factors associated with human immunodeficiency virus (HIV) co-infection in cases of acquired syphilis reported in a Reference Center for Sexually Transmitted Diseases (STD) and AIDS. METHODS: cross-sectional study with secondary data from a Reference Center for STD and AIDS in the municipality of Sao Paulo, Brazil, in 2014; the Poisson regression was used to estimate prevalence ratios (PR) and 95% confidence intervals (95%CI). RESULTS: 648 cases of acquired syphilis were reported, and 98% were male; 88% were men who have sex with men (MSM) and 57% had HIV co-infection; male sex (PR=1.95; 95%CI 1.05;3.61) and MSM (PR=1.87; 95%CI 1.38;2.53) were factors independently associated with HIV co-infection. CONCLUSION: there was a high prevalence of HIV co-infection in the service analyzed, disproportionately affecting MSM who were notified with acquired syphilis.

PMID- 29451618 TI - The Association of Vitamin D Levels and the Frailty Phenotype Among Non-geriatric Dialysis Patients: A Cross-sectional Study. AB - OBJECTIVES: The aim of this study was to investigate the frequency of frailty and the association of vitamin D levels and the frailty phenotype among non-geriatric dialysis patients. METHOD: Seventy-four stable, chronic hemodialysis patients from the hemodialysis unit of the hospital were enrolled in the study. The patients' medical histories and laboratory findings were obtained from the medical records of the dialysis unit. Serum parathyroid hormone and 25-hydroxy vitamin D levels were determined using chemiluminometric immunoassays. Frailty was defined by Fried et al. as a phenotype; shrinking, weakness, self-reported exhaustion, decreased activity and slowed walking speed were evaluated. RESULTS: Forty-one (55%) of the patients were males. The patients were divided into 3 groups according to frailty scores: 39 (53%) patients were frail, 6 (8%) patients were intermediately frail, and 28 (39%) patients were normal. Significant differences were found for 25-hydroxy vitamin D and hemoglobin levels among the groups; however, no differences were observed in body mass index, comorbidities, sex, marital status, education, disease and dialysis durations, or parathyroid hormone, creatinine, serum calcium, phosphorus, and potassium levels. CONCLUSIONS: Weakness and slowness are serious outcomes of both vitamin D deficiency and frailty, and vitamin D deficiency has been associated with increased risks of decreased physical activity, falls, fractures and death in postmenopausal women and older men. Although studies on frailty have focused on older adults, growing evidence indicates that the frailty phenotype is becoming a factor associated with poor health outcomes in non-geriatric populations with chronic disease. PMID- 29451619 TI - Increase of 10% in the Rate of Adverse Drug Reactions for Each Drug Administered in Hospitalized Patients. AB - OBJECTIVE: To assess the risk factors, incidence and severity of adverse drug reactions in in-patients. METHODS: This prospective study evaluated 472 patients treated at a teaching hospital in Brazil between 2010 and 2013 by five medical specialties: Internal Medicine, General Surgery, Geriatrics, Neurology, and Clinical Immunology and Allergy. The following variables were assessed: patient age, gender, comorbidities, family history of hypersensitivity, personal and family history of atopy, number of prescribed drugs before and during hospitalization, hospital diagnoses, days of hospitalization. The patients were visited every other day, and medical records were reviewed by the investigators to detect adverse drug reactions. RESULTS: There were a total of 94 adverse drug reactions in 75 patients. Most reactions were predictable and of moderate severity. The incidence of adverse drug reactions was 16.2%, and the incidence varied, according to the medical specialty; it was higher in Internal Medicine (30%). Antibiotics were the most commonly involved medication. Chronic renal failure, longer hospital stay, greater number of diagnoses and greater number of medications upon admission were risk factors. For each medication introduced during hospitalization, there was a 10% increase in the rate of adverse drug reaction. In the present study, the probability of observing an adverse drug reaction was 1 in 104 patients per day. CONCLUSIONS: Adverse drug reactions are frequent and potentially serious and should be better monitored in patients with chronic renal failure or prolonged hospitalization and especially in those on 'polypharmacy' regimens. The rational use of medications plays an important role in preventing adverse drug reactions. PMID- 29451620 TI - Application of a pharmacokinetics-pharmacodynamics approach to the free propofol plasma levels during coronary artery bypass grafting surgery with hypothermic cardiopulmonary bypass. AB - OBJECTIVES: The objective of this study was to apply a pharmacokinetics pharmacodynamics approach to investigate the free propofol plasma levels in patients undergoing coronary artery bypass grafting under hypothermic conditions compared with the off-pump procedure. METHODS: Nineteen patients scheduled for on pump coronary artery bypass grafting under hypothermic conditions (n=10) or the equivalent off-pump surgery (n=9) were anesthetized with sufentanil and propofol target-controlled infusion (2 MUg/mL) during surgery. The propofol concentration was then reduced to 1 MUg/mL, and a pharmacokinetics-pharmacodynamics analysis using the maximum-effect-sigmoid model obtained by plotting the bispectral index values against the free propofol plasma levels was performed. RESULTS: Significant increases (two- to five-fold) in the free propofol plasma levels were observed in the patients subjected to coronary artery bypass grafting under hypothermic conditions. The pharmacokinetics of propofol varied according to the free drug levels in the hypothermic on-pump group versus the off-pump group. After hypothermic coronary artery bypass was initiated, the distribution volume increased, and the distribution half-life was prolonged. Propofol target controlled infusion was discontinued when orotracheal extubation was indicated, and the time to patient extubation was significantly higher in the hypothermic on pump group than in the off-pump group (459 versus 273 min, p=0.0048). CONCLUSIONS: The orotracheal intubation time was significantly longer in the hypothermic on-pump group than in the off-pump group. Additionally, residual hypnosis was identified through the pharmacokinetics-pharmacodynamics approach based on decreases in drug plasma protein binding in the hypothermic on-pump group, which could explain the increased hypnosis observed with this drug in this group of patients.

AB - Our aim in this study was to compare the efficiency of 25G versus 22G needles in diagnosing solid pancreatic lesions by EUS-FNA. We performed a systematic review and meta-analysis. Studies were identified in five databases using an extensive search strategy. Only randomized trials comparing 22G and 25G needles were included. The results were analyzed by fixed and random effects. A total of 504 studies were found in the search, among which 4 randomized studies were selected for inclusion in the analysis. A total of 462 patients were evaluated (233: 25G needle/229: 22G needle). The diagnostic sensitivity was 93% for the 25G needle and 91% for the 22G needle. The specificity of the 25G needle was 87%, and that of the 22G needle was 83%. The positive likelihood ratio was 4.57 for the 25G needle and 4.26 for the 22G needle. The area under the sROC curve for the 25G needle was 0.9705, and it was 0.9795 for the 22G needle, with no statistically significant difference between them (p=0.497). Based on randomized studies, this meta-analysis did not demonstrate a significant difference between the 22G and 25G needles used during EUS-FNA in the diagnosis of solid pancreatic lesions.

AB - OBJECTIVE: To analyze the proportion of expenditure and its frequency in food and beverages consumed inside and outside of households, at national and regional level, in Mexico between 1984 and 2014. MATERIALS AND METHODS: It analyzes data of household expenditure of food and beverages taken from the National Survey of Mexican Household Income and Expenditures 1984, 1994, 2005 and 2014. It conducted descriptive statistics analyses such as percentages, growth rates and crosstabs. RESULTS: There were changes in food expenditure patterns at national and regional level. The proportion of expenditure and its frequency increased in non-alcoholic beverages, prepared food, meals made outside home and cereals. The proportion of expenditure and its frequency decreased in oils and fats, fruits, vegetables, sugar and honeys. CONCLUSION: These changes can be related to political, economic, social and cultural transformations experienced in the last decades.

AB - OBJECTIVE: To assess the effect of Education in Nutrition and Food Assistance components of the SaludArte program in participant schools during 2013-2015. MATERIALS AND METHODS: A three cohort comparative study was used, with two type of follow-up panel structures: a complete panel and a continuous time, with a total of consisting on 1620 scholar children from 144 schools. Information on food intake, feeding behaviors, food preservation and hygiene, physical activity (PI) and anthropometry was registered. To stablish effect estimates, a difference in difference method combined with propensity score matching was carried out; as an alternative procedure, logistic-multinomial and logistic regression models were also used. RESULTS: Program attributable estimated effects were as follows: an increase in personal hygiene (p=0.045), increase in nutrition knowledges (p=0.003), PI (p=0.002 2013-2014; p=0.032 2015) and increase in fiber Intake (p=0.064). Sugar intake, contrary to the expected showed a significant increase (p=0.012 continuous time and; p=0.037 complete time). CONCLUSIONS: SaludArte shows positive effects over some components as expected. However in order to institutionalize the SaludArte program, it is necessary to consider these learned lessons, give it permanence and impulse it in the schools.

AB - OBJECTIVE.: To assess the association between the air pollutants exposure on markers of oxidative stress and lung function in schoolchildren with and without asthma from Salamanca and Leon Guanajuato, Mexico. MATERIALS AND METHODS: We realized determinations of oxidative stress biomarkers and lung function tests in 314 schoolchildren. Information of air pollutants (O3, SO2, CO, PM2.5 and PM10) were obtained from monitoring stations and multiple linear regression models were run to assess the association. RESULTS: An increase of 0.09 pmol in conjugated dienes was observed by exposure to PM10 lag 1 in asthmatics from Salamanca (p<0.05). The exposure to O3 during the same day increased the concentration of Lipohydroperoxides in 4.38 nmol in asthmatics of Salamanca, as well as in 2.31 nmol by exposure to PM10 lag 2 (p<0.05). The forced vital capacity decreased by 138 and 203 ml in children without asthma, respectively, due to exposure to carbon monoxide (p<0.05). CONCLUSIONS: Exposure to air pollutants increase oxidative stress and decreased lung function in schoolchildren, with and without asthma. PMID- 29451633 TI - [Inequity in maternal mortality in Mexico: analyzing inequality on a sub-state regional scale]. AB - OBJECTIVE: To estimate maternal mortality ratios (MMR) for the different sub state regions in Mexico in order to identify those with highest maternal mortality, as well as the degree of inter-regional inequality. MATERIALS AND METHODS: Maternal mortality and registered live births data was taken from publicly available official data for the years 2005 to 2014. We regionalized the states based on political-administrative divisions within them and calculated MMR for these regions, and calculated Gini coefficients. RESULTS: MMR for sub-state regions ranges from 16 (Non-Metropolitan Nuevo Leon State) to 160 (Sola de Vega, Oaxaca). We identified 13 regions of Very High or Extremely High maternal mortality. The national Gini coefficient is 0.175, with the states of Chihuahua, Nayarit, Oaxaca and Guerrero standing out for their unequal distribution of maternal mortality within their territory. CONCLUSIONS: Even state level averages of maternal mortality rates tend to hide important inequalities within states, which reflect multiple subjacent inequities.

AB - OBJECTIVE: To evaluate the epidemiological behavior of varicella and herpes zoster (HZ) to determine the need of health policies to diminish prevalence and avoid complications. MATERIALS AND METHODS: To assess frequency, we analyzed data from the National Information System for Epidemiological Surveillance (SUIVE) from 2000 to 2013; to assess the discharge data of varicella and HZ, we evaluated information from the National System of health information (Sinais). RESULTS: The average annual cases of chickenpox were 296 733, 57% mostly children under 9 years, most of them from March to May. From 2004 to 2012 hospital discharge of varicella were 17 398, of which 4.6% had meningoecephalitis, 2.5% pneumonia and 18% other complications. For herpes zoster 7 042 discharges, mostly affected were patients 65 years or older, 1.3:1 the woman-man relationship. Main complications were: neuralgia (11%), eye involvement (7%), meningoencephalitis (5.4%), disseminated disease (2.8%) and others (5.4%); hospital stay was between 6.4 and 13.3 days. CONCLUSIONS: Data is consistent with that of the literature in other countries. The role of vaccination to prevent infection in children and adults is discussed.

AB - OBJETIVE: To evaluate the serum 25-hydroxyvitamin D (25-OH-D) levels in healthy children under 10 years of the Barranquilla metropolitan area. MATERIALS AND METHODS: A descriptive cross-sectional study in which serum levels of 25-OH-D were analyzed in 360 healthy children from 2014 to 2015. RESULTS: The median value of 25-OH-D serum level was 32.23+/-8.56 ng/mL; 46.38% of children had vitamin D levels in the insufficient range (<30 ng/mL), while 3.05% were deficient (<20 ng/mL). Soledad and Puerto Colombia were the municipalities with more population in this condition. CONCLUSIONS: It is necessary to promote vitamin D supplement consumption and healthy lifestyles in order to safely improve levels of this micronutrient in the population.

AB - OBJECTIVE: Describe the occurrence of potentially traumatic events (PTE) in high school students, measure subthreshold post-traumatic symptomatology in those who still experience PTE repercussions and associate the symptomatology with sociodemographic and PTE characteristics. MATERIALS AND METHODS: Analytic transversal study carried out in a convenience sample of one thousand students from three high schools in the State of Mexico. The Scale for Post Traumatic Stress in University Students was applied. The presence of symptoms, their frequency and their association with explanatory variables was assessed by means of logistic and quantile logistic regression models, respectively. RESULTS: 80% reported PTE. Of this, 79% still experienced current repercussions and almost a half presented symptomatology. Gender, number of events, and PTE characteristics (perceived and grave symptoms) were associated. CONCLUSIONS: Results suggest to intervene early to reduce the risk of developing a disorder. PMID- 29451637 TI - Facing death in the clinical practice: a view from nurses in Mexico. AB - OBJECTIVE: To explore the views of nurses on death in their practice, and their perception about physicians' actions dealing with terminally ill patients. MATERIALS AND METHODS: Two hundred ninety-five nurses with experience caring for terminally ill patients responded to a questionnaire developed for this study. RESULTS: The majority of participants considered that terminally ill patients should know about their prognosis. Although nearly all nurses said that when a patient brings up the subject and they talk with the patient about death, several of the nurses find it difficult to establish a relationship with these patients. Concerning nurses' perception about physicians' actions, they considered that physicians avoid the subject of death with their patients more than the physicians acknowledge. CONCLUSIONS: More education and training of physicians and nurses on end-of-life issues is needed to improve communication with dying patients and to provide them with better care. PMID- 29451638 TI - [Association between health anthropometric indexes with physical fitness in physically active elderly women]. AB - OBJECTIVE: To associate health anthropometric indexes with physical fitness of elderly women (EW) who participate in physical exercise workshops. MATERIALS AND METHODS: 272 Chilean women over 60 years took part in the study. The variables studied were BMI, waist circumference (WC), waist-height index (WHI) and physical fitness (PF). Correlations were made through the Pearson or Spearman coefficient, and bivariate associations using Pearson's Chi-square and the Fisher's exact test, considering p<0.05. RESULTS: 70.8% of the EW were overweight or obese; 68.8% and 96% were at cardiometabolic risk due to their WC and WHI, respectively. Their PF showed equal performance (53.5%) or higher (33.8%) according to their age and gender. Inverse correlations were found between nutritional status and cardiometabolic risk with PF tests (except for agility and dynamic balance [direct]), and direct association with back scratch test. CONCLUSIONS: Excess weight in physically active EW would not affect their physical-functional performance; however, cardiometabolic risk would be inversely associated with motor function.

AB - OBJECTIVE: To examine food advertising aimed at childhood's audience broadcast on Chilean television. MATERIALS AND METHODS: Cross-sectional study. Food advertising broadcast by 4 open signal TV channels was recorded for 12 hours daily on twelve days randomly selected. Notices were classified according to food groups and level of processing. The frequency of food advertisement aimed to childhood audience was compared with those for adults. Nutrient profile of foods advertised was described. RESULTS: In 144 hours of recording appeared 530 food advertisement; 53.2% were aimed to childhood audience. The most advertised foods were sugary dairy (28.4%), sweetened beverages (25.5%), and sweetened cereals (17.7%). Of the foods advertised to childhood audience, 75% exceeds the criterion for free sugars. CONCLUSIONS: Chilean television advertises ultra-processed foods that exceed the limits of free sugars. PMID- 29451640 TI - Glucose level evaluation in monopedicled rectus abdominis myocutaneous flap after venous occlusion: experimental study in rats. AB - OBJECTIVE: to validate an experimental model for the measurement of glycemic levels in surgical flaps with the use of common glucometers, and to analyze the diagnostic criteria for hypoperfusion of such flaps. METHODS: we performed vertical myocutaneous rectus abdominis flaps with upper pedicles bilaterally in 20 male Wistar rats, divided into two groups: with and without venous occlusion of the pedicle. We measured glucose levels in the flaps and in the systemic circulation with standard glucometers. We tested the accuracy of alternative diagnostic criteria for the detection of hypoperfusion. RESULTS: from 15 minutes of venous occlusion on, there was a significant reduction in glucose levels measured in the congested flap (p<0.001). Using a minimum difference of 20mg/dl in the glycemic levels between the flap and systemic blood, 30 minutes after occlusion, as a diagnostic criterion, the sensitivity was 100% (95% CI 83.99 100%) and specificity of 90% (95% CI 69.90-97.21%) for the diagnosis of flap congestion. CONCLUSION: It is possible to measure glucose levels in vertical myocutaneous rectus abdominis flaps of Wistar rats, perfused or congested, using a common glucometer. The diagnostic criteria that compare the glucose levels in the flaps with the systemic ones were more accurate in the evaluation of tissue perfusion. PMID- 29451642 TI - Damage control surgery: are we losing control over indications? AB - OBJECTIVE: to analyze the surgeons' subjective indications for damage control surgery, correlating with objective data about the patients' physiological state at the time the surgery was chosen. METHODS: we carried out a prospective study between January 2016 and February 2017, with 46 trauma victims who were submitted to damage control surgery. After each surgery, we applied a questionnaire to the attending surgeon, addressing the motivations for choosing the procedure. We collected data in the medical records to assess hemodynamic conditions, systolic blood pressure and heart rate on arrival at the emergency room (grade III or IV shock on arrival at the emergency room would partially justify the choice). We considered elevation of serum lactate level, prolonged prothrombin time and blood pH below 7.2 as laboratory indicators of worse prognosis, objectively corroborating the subjective choice of the procedure. RESULTS: the main indications for damage control surgery were hemodynamic instability (47.8%) and high complexity lesions (30.4%). Hemodynamic and laboratory changes corroborated the choice in 65.2% of patients, regardless of the time; 23.9% presented hemodynamic changes compatible with degree III and IV shock, but without laboratory alterations; 4.3% had only laboratory abnormalities and 6.5% had no alterations at all. CONCLUSION: in the majority of cases, there was early indication for damage control surgery, based mainly on hemodynamic status and severity of lesions, and in 65.2%, the decision was compatible with alterations in objective hemodynamic and laboratory data. PMID- 29451641 TI - Splenic implant preservation after conservation in lactated Ringer's solution. AB - OBJECTIVE: to evaluate the morphology and function of autogenous splenic tissue implanted in the greater omentum, 24 hours after storage in Ringer-lactate solution. METHODS: we divided 35 male rats into seven groups (n=5): Group 1: no splenectomy; Group 2: total splenectomy without implant; Group 3: total splenectomy and immediate autogenous implant; Group 4: total splenectomy, preservation of the spleen in Ringer-lactate at room temperature, then sliced and implanted; Group 5: total splenectomy, spleen sliced and preserved in Ringer lactate at room temperature before implantation; Group 6: total splenectomy with preservation of the spleen in Ringer-lactate at 4 degrees C and then sliced and implanted; Group 7: total splenectomy and the spleen sliced for preservation in Ringer-lactate at 4 degrees C before implantation. After 90 days, we performed scintigraphic studies with Tc99m-colloidal tin (liver, lung, spleen or implant and clot), haematological exams (erythrogram, leucometry, platelets), biochemical dosages (protein electrophoresis) and anatomopathological studies. RESULTS: regeneration of autogenous splenic implants occurred in the animals of the groups with preservation of the spleen at 4oC. The uptake of colloidal tin was higher in groups 1, 3, 6 and 7 compared with the others. There was no difference in hematimetric values in the seven groups. Protein electrophoresis showed a decrease in the gamma fraction in the group of splenectomized animals in relation to the operated groups. CONCLUSION: the splenic tissue preserved in Ringer lactate solution at 4oC maintains its morphological structure and allows functional recovery after being implanted on the greater omentum. PMID- 29451643 TI - The applicability of POSSUM and P-POSSUM scores as predictors of morbidity and mortality in colorectal surgery. AB - OBJECTIVE: to apply the POSSUM and P-POSSUM scores as a tool to predict morbidity and mortality in colorectal surgery. METHODS: we conducted a prospective cohort study of 551 patients submitted to colorectal surgery in a colorectal surgery tertiary referral hospital in Brazil. We grouped patients into pre-established risk categories for comparison between expected and observed morbidity and mortality rates by the POSSUM and P-POSSUM scores. RESULTS: in the POSSUM morbidity analysis, the overall expected morbidity was significantly higher than that observed (39.2% vs. 15.6%). The same occurred with patients grouped in categories II (28.9% x 10.5) and III (64.6% x 24.5%). In category I, the expected and observed morbidities were similar (13.7% x 9.1%). Regarding the evaluation of mortality, it was statistically higher than that observed in category III patients and in the total number of patients (11.3% vs. 5.6%). In categories I and II, we observed the same pattern of category III, but without statistical significance. When evaluating mortality by the P-POSSUM score, the overall expected and observed mortality was similar (5.8% x 5.6%). Of the 31 patients who died, 20.2% underwent emergency procedures and sepsis was the main cause of death. CONCLUSION: the P-POSSUM score was an accurate tool to predict mortality and could be safely used in this population profile, unlike the POSSUM score. PMID- 29451644 TI - Scrotal reconstruction with superomedial fasciocutaneous thigh flap. AB - OBJECTIVE: to describe the use of a superomedial fasciocutaneous thigh flap for scrotal reconstruction in open areas secondary to the surgical treatment of perineal necrotizing fasciitis (Fournier's gangrene). METHODS: retrospective analysis of cases treated at the Plastic Surgery Service of Santa Casa de Misericordia, Sao Paulo, from 2009 to 2015. RESULTS: fifteen patients underwent scrotal reconstruction using the proposed flap. The mean age was 48.9 years (28 to 66). Skin loss estimates in the scrotal region ranged from 60 to 100%. Definitive reconstruction was performed on average 30.6 days (22 to 44) after the initial surgical treatment. The mean surgical time was 76 minutes (65 to 90) to obtain the flaps, bilateral in all cases. Flap size ranged from 10cm to 13cm in the longitudinal direction and 8cm to 10cm in the cross-sectional direction. The complication rate was 26.6% (four cases), related to the occurrence of segmental and partial dehiscence. CONCLUSION: the superomedial fasciocutaneous flap of thigh is a reliable and versatile option for the reconstruction of open areas in the scrotal region, showing adequate esthetic and functional results. PMID- 29451645 TI - Intragastric balloons in high-risk obese patients in a Brazilian center: initial experience. AB - OBJECTIVE: to assess the short-term efficacy, tolerance and complications in high risk morbidly obese patients treated with an intragastric balloon as a bridge for surgery. METHODS: we conducted a post-hoc analysis study in a Brazilian teaching hospital from 2010 to 2014, with 23 adult patients with a BMI of 48kg/m2, who received a single intragastric air or liquid balloon. We defined efficacy as 10% excess weight loss, and complications, as adverse events consequent to the intragastric balloon diagnosed after the initial accommodative period. We expressed the anthropometric results as means +/- standard deviation, comparing the groups with paired T / Student's T tests, when appropriate, with p<0.05 considered statistically significant. RESULTS: the balloons were effective in 91.3% of the patients, remained in situ for an average of 5.5 months and most of them (65.2%) were air-filled, with a mean excess weight loss of 23.7kg+/-9.7 (excess weight loss 21.7%+/-8.9) and mean BMI reduction of 8.3kg/m2+/-3.3. Complications (17.3%) included abdominal discomfort, balloon deflation and late intolerance, without severe cases. Most of the participants (82.7%) did not experience adverse effects. We removed the intragastric balloons in time, without intercurrences, and 52.2% of these patients underwent bariatric surgery within one month. CONCLUSION: in our center, intragastric balloons can be successfully used as an initial weight loss procedure, with good tolerance and acceptable complications rates. PMID- 29451646 TI - Profile of patients with Fournier's gangrene and their clinical evolution. AB - OBJECTIVE: to analyze the profile of patients with Fournier's gangrene treated in a public tertiary hospital in western Parana State. METHODS: we conducted a cross sectional, retrospective and descriptive study of patients with Fournier's gangrene treated between January 2012 and November 2016. RESULTS: there were 40 patients with Fournier's gangrene treated in the period, 29 (72.5%) men and 11 (27.5%) women. The mean age was 51.7+/-16.3 years. The mean time of disease progression, from the initial symptom to hospitalization, was 10.5+/-1.2 days. All patients had clinical signs such as pain, bulging, erythema, among others, and 38 (95%) had associated comorbidities, the most common being type 2 diabetes mellitus and systemic arterial hypertension. The majority (30 patients - 75%) had perianal abscess as the probable etiology. All patients were submitted to antibiotic therapy and surgical treatment, with a mean of 1.8+/-1.1 surgeries per patient. Nine (22.5%) patients died. There was a strong correlation between the presence of sepsis on admission and mortality. CONCLUSION: Fournier's gangrene patients in this series had a long disease duration and a high prevalence of comorbidities, with a high mortality rate. PMID- 29451647 TI - Criopreserved ovarian tissue transplantation and bone restoration metabolism in castrated rats. AB - OBJECTIVES: to evaluate estradiol levels and autotransplantation heated ovarian tissue effects, after vitrification, on rats bone metabolism previously oophorectomized bilaterally. METHODS: experimental study with 27 rats aged 11 to 12 weeks and weighing 200g to 300g, submitted to bilateral oophorectomy and ovarian tissue cryopreservation for subsequent reimplantation. Animals were divided into two groups, A and B, with 8 and 19 rats, respectively. Autotransplantation occurred in two periods according to castration time: after one week, in group A, and after one month in group B. Serum estradiol measurements and ovary and tibia histological analysis were performed before and after oophorectomy period (early or late) and one month after reimplantation. RESULTS: in groups A and B, tibia median cortical thickness was 0.463+/-0.14mm (mean+/-SD) at the baseline, 0.360+/-0.14mm after oophorectomy and 0.445+/-0.17mm one month after reimplantation p<0.005). Trabecular means were 0.050+/-0.08mm (mean+/-SD) at baseline, 0.022+/-0.08mm after oophorectomy and 0.049+/-0.032mm one month after replantation (p<0.005). There was no statistical difference in estradiol variation between the two study groups (p=0.819). CONCLUSION: cryopreserved ovarian tissue transplantation restored bone parameters, and these results suggest that ovarian reimplantation in women may have the same beneficial effects on bone metabolism. PMID- 29451648 TI - 3-D finite element analysis of the effects of post location and loading location on stress distribution in root canals of the mandibular 1st molar. AB - Objective The purpose of this study was to evaluate, by using finite element analysis, the influence of post location and occlusal loading location on the stress distribution pattern inside the root canals of the mandibular 1st molar. Material and Methods Three different 3-D models of the mandibular 1st molar were established: no post (NP) - a model of endodontic and prosthodontic treatments; mesiobuccal post (MP) - a model of endodontic and prosthodontic treatments with a post in the mesiobuccal canal; and distal post (DP) - a model of endodontic and prosthodontic treatments with a post in the distal canal. A vertical force of 300 N, perpendicular to the occlusal plane, was applied to one of five 1 mm2 areas on the occlusal surface; mesial marginal ridge, distal marginal ridge, mesiobuccal cusp, distobuccal cusp, and central fossa. Finite element analysis was used to calculate the equivalent von Mises stresses on each root canal. Results The DP model showed similar maximum stress values to the NP model, while the MP model showed markedly greater maximum stress values. The post procedure increased stress concentration inside the canals, although this was significantly affected by the site of the force. Conclusions In the mandibular 1st molar, the distal canal is the better place to insert the post than the mesiobuccal canal. However, if insertion into the mesiobuccal canal is unavoidable, there should be consideration on the occlusal contact, making central fossa and distal marginal ridge the main functioning areas. PMID- 29451649 TI - The effects of different restorative materials on periodontopathogens in combined restorative-periodontal treatment. AB - Objective The aim of the study was to evaluate the association between subgingival restorations and the target periodontopathogenic bacteria (Pg, Td and Pi) in subgingival biofilm during one year after combined restorative-periodontal treatment. Material and Methods Seventeen systemically healthy subjects, who were positive for the presence of three cervical lesions associated with gingival recessions in three different adjacent teeth, were included in the study. A total of 51 combined defects were treated with connective tissue graft plus a nanofilled composite resin (NCR+CTG), a resin-modified glass ionemer cement (RMGI+CTG) and a fluoride-releasing resin material with pre-reacted glass (PRG), called giomer (Giomer+CTG). Periodontal clinical measurements and subgingival plaque samples were obtained from all combined defects at baseline and at 6 and 12 months after the surgery. The number of bacteria were evaluated by the real time polymerase chain reaction (qPCR) method. Results No statistically significant difference in the amount of DNA copies of Pg, Td and Pi was observed in any of the groups at any time points (p>0.05). In addition, there was no statistically significant difference in the amount of DNA copies of the bacteria at baseline and at 6 and 12 months postoperatively, regardless of treatment group (p>0.05). Conclusion This study suggests that subgingivally placed NCR, RMGI and giomer restorations can show similar effects on periodontopathogenic bacteria in the treatment of gingival recessions that are associated with noncarious cervical lesions (NCCLs). PMID- 29451650 TI - Comparison of deflection forces of esthetic archwires combined with ceramic brackets. AB - Coated archwires and ceramic brackets have been developed to improve facial esthetics during orthodontic treatment. However, their mechanical behavior has been shown to be different from metallic archwires and brackets. Therefore, the aim of this study was to compare the deflection forces in coated nickel-titanium (NiTi) and esthetic archwires combined with ceramic brackets. Material and Methods Non-coated NiTi (NC), rhodium coated NiTi (RC), teflon coated NiTi (TC), epoxy coated NiTi (EC), fiber-reinforced polymer (FRP), and the three different conventional brackets metal-insert polycrystalline ceramic (MI-PC), polycrystalline ceramic (PC) and monocrystalline ceramic (MC) were used. The specimens were set up on a clinical simulation device and evaluated in a Universal Testing Machine (Instron). An acrylic device, representative of the right maxillary central incisor was buccolingually activated and the unloading forces generated were recorded at 3, 2, 1 and 0.5 mm. The speed of the testing machine was 2 mm/min. ANOVA and Tukey tests were used to compare the different archwires and brackets. Results The brackets presented the following decreasing force ranking: monocrystalline, polycrystalline and polycrystalline metal-insert. The decreasing force ranking of the archwires was: rhodium coated NiTi (RC), non coated NiTi (NC), teflon coated NiTi (TC), epoxy coated NiTi (EC) and fiber reinforced polymer (FRP). At 3 mm of unloading the FRP archwire had a plastic deformation and produced an extremely low force in 2; 1 and 0.5 mm of unloading. Conclusion Combinations of the evaluated archwires and brackets will produce a force ranking proportional to the combination of their individual force rankings. PMID- 29451652 TI - Animal experimentation: A look into ethics, welfare and alternative methods. PMID- 29451651 TI - Demetallization of Enterococcus faecalis biofilm: a preliminary study. AB - Objectives To determine the concentration of calcium, iron, manganese and zinc ions after the application of chelator to Enterococcus faecalis biofilms. Material and Methods Fifty bovine maxillary central incisors were prepared and inoculated with E. faecalis for 60 days. The following were used as irrigation solutions: 17% EDTA (pH 3, 7 and 10), 2.5% sodium hypochlorite (NaOCl) combined with 17% EDTA (pH 3, 7 and 10), distilled water (pH 3, 7 and 10), and 2.5% NaOCl. Each solution was kept in the root canal for five minutes. Fifteen uncontaminated root canals were irrigated with 17% EDTA (pH 3, 7 and 10). Six teeth were used as bacterial control. The number of calcium, iron, manganese and zinc ions was determined using flame atomic absorption spectrometry. Mean +/- standard deviation (SD) values were used for descriptive statistics. Results Calcium chelation using 17% EDTA at pH 7 was higher than at pH 3 and 10, regardless of whether bacterial biofilm was present. The highest concentration of iron occurred at pH 3 in the presence of bacterial biofilm. The highest concentration of manganese found was 2.5% NaOCl and 17% EDTA at pH 7 in the presence of bacterial biofilm. Zinc levels were not detectable. Conclusions The pH of chelating agents affected the removal of calcium, iron, and manganese ions. The concentration of iron ions in root canals with bacterial biofilm was higher after the use of 17% EDTA at pH 3 than after the use of the other solutions at all pH levels.

PMID- 29451655 TI - Human polyomavirus infection: Cytological and molecular diagnosis. AB - Few studies directly compare urinary cytology with molecular methods for detecting BK and JC polyomaviruses. Reactivation of BKV infection is the main risk factor for the development of nephropathy in immunocompromised individuals. The limitation of the cytological method can be attributed to the stage where the infected cell does not have specific and sufficient morphological characteristics for a conclusive diagnosis and can be easily interpreted as degenerative alteration. Moreover, morphologically, it is not possible to differentiate the two types of viruses. Polymerase chain reaction (PCR), not only is a sensitive method, but also allows differentiation of viral types without quantification, and therefore is not indicative of nephropathy. According to the American Society of Nephrology, real-time PCR would be the gold standard to indicate nephropathy because it allows quantifying the number of viral copies. PMID- 29451656 TI - Posterior fossa decompression with duraplasty in Chiari surgery: A technical note. AB - Chiari malformation (CM) is the most common and prevalent symptomatic congenital craniocervical malformation. Radiological diagnosis is established when the cerebellar tonsils are located 5 mm or more below the level of the foramen magnum on magnetic resonance imaging (MRI). Surgical treatment is indicated whenever there is symptomatic tonsillar herniation or syringomyelia/hydrocephalus. The main surgical treatment for CM without craniocervical instability (such as atlantoaxial luxation) is posterior fossa decompression, with or without duraplasty. The authors describe in details and in a stepwise fashion the surgical approach of patients with CM as performed at the State University of Campinas, emphasizing technical nuances for minimizing the risks of the procedure and potentially improving patient outcome. PMID- 29451657 TI - Malignant fibrous histiocytoma in a patient presenting with urinary system symptoms. AB - Malignant fibrous histiocytoma is a rare tumor. It is most commonly seen in individuals between the fifth and seventh decades of life, in extremities, and less frequently in the retroperitoneum. Although its etiology is not clearly known, radiotherapy, chemical agents, previous history of surgery, trauma and fracture, and Hodgkin lymphoma have been blamed. Leiomyosarcoma, liposarcoma and rhabdomyosarcoma should be taken into account in differential diagnosis. It is seen on computed tomography as a mass lesion with irregular borders and density similar to that of the surrounding muscle tissue. Necrotic and hemorrhagic components in the mass are characterized as heterogeneous low density areas. Fluid-fluid levels can be detected by computed tomography and magnetic resonance imaging. PMID- 29451658 TI - Clinical correlation of biopsy results in patients with temporal arteritis. AB - OBJECTIVE: Temporal arteritis is systemic vasculitis of medium and large sized vessels. The lowest incidence rates were reported in Turkey, Japan and Israel. We aimed to investigate the results of patients with biopsy-proven temporal arteritis and those classified according to the American College of Rheumatology criteria from a low-incidence region for temporal arteritis. The results of our study are noteworthy, since there is limited data on pathologic diagnosis of temporal arteritis in Turkey. METHOD: We studied the medical records, laboratory findings such as erythrocyte sedimentation rate and C-reactive protein levels, biopsy results, and postoperative complications of all the patients operated for temporal artery biopsy at our clinic. We used the computerized laboratory registry that keeps all records of 42 consecutive temporal artery biopsy results from January 2011 to December 2016. RESULTS: The mean age was 66+/-12.5 years. The most common manifestations on admission were temporal headache, optic neuritis and jaw claudication, respectively. Temporal artery biopsy results confirmed tempoal arteritis in eight out of 42 (19%) patients. There was no statistically significant difference between biopsy-positive and biopsy-negative groups in terms of sex, age, erythrocyte sedimentation rate, C-reactive protein and biopsy length. CONCLUSION: We were not able to find a correlation between the analysis of biopsy results and clinical evaluation of patients with temporal arteritis. We suggest that diagnosis of temporal arteritis depends on clinical suspicion. Laboratory examination results may not be helpful in accurate diagnosis of tempoal arteritis. PMID- 29451659 TI - Environmental factors can influence dengue reported cases. AB - INTRODUCTION: Global climate changes directly affect the natural environment and contribute to an increase in the transmission of diseases by vectors. Among these diseases, dengue is at the top of the list. The aim of our study was to understand the consequences of temporal variability of air temperature in the occurrence of dengue in an area comprising seven municipalities of the Greater Sao Paulo. METHOD: Characterization of a temporal trend of the disease in the region between 2010 and 2013 was performed through analysis of the notified number of dengue cases over this period. Our analysis was complemented with meteorological (temperature) and pollutant concentration data (PM10). RESULTS: We observed that the months of January, February, March, April and May (from 2010 to 2013) were the ones with the highest number of notified cases. We also found that there is a statistical association of moisture and PM10 with the reported cases of dengue. CONCLUSION: Although the temperature does not statistically display an association with recorded cases of dengue, we were able to verify that temperature peaks coincide with dengue outbreak peaks. Future studies on environmental pollution and its influence on the development of Aedes aegypti mosquito during all stages of its life cycle, and the definition of strategies for better monitoring, including campaigns and surveillance, would be compelling. PMID- 29451660 TI - Economic assessment of postoperative pain control strategies for treatment of adult patients with cancer. AB - OBJECTIVE: The authors performed an economic assessment of opioids currently being used for control of postoperative pain relating to the surgical treatment of cancer (fentanyl and sufentanil) within the Brazilian Unified Health System (SUS, in the Portuguese acronym). METHOD: The assessment was based on the perspective of the government, in order to collaborate with the promotion of effectiveness in public policies of health, and to optimize the allocation of public resources into health. A cost-effectiveness analysis was performed using data collected from the Brazilian Unified Health System and information from literature review, in order to build a decision tree on the alternatives for control of postoperative pain related to cancer treatment among adult patients. The outcomes considered were: effectiveness of postoperative analgesia and occurrence of nausea and vomit in the 48 hour period after surgery, and additional 24-hour cycles in patient follow-up. A univariate sensitivity analysis was conducted in order to verify robustness of the model estimated. RESULTS: Literature review showed a limited number of studies directly comparing fentanyl and sufentanil for control of postoperative pain. The adoption of sufentanil (cost = U$ 25.72 / outcome = 1.6 VAS points) was dominant in relation to the use of fentanyl (cost = U$ 32.58 / outcome = 2.6 VAS points). The estimated model showed robustness in relation to changes in the parameters analyzed. CONCLUSION: Sufentanil presented higher cost-effectiveness ratio in relation to fentanyl for control of postoperative pain in surgeries related to cancer treatment among adult patients in the Brazilian Unified Health System. PMID- 29451661 TI - Association between the RAGE (receptor for advanced glycation end-products) 374T/A gene polymorphism and diabetic retinopathy in T2DM. AB - OBJECTIVE: Interaction between advanced glycation end-products (AGEs) and receptor for AGEs (RAGE) in cells could affect both extracellular and intracellular structure and function, which plays a pivotal role in diabetic microvascular complications. The results from previous epidemiological studies on the association between RAGE gene -374T/A polymorphism and diabetic retinopathy (DR) risk were inconsistent. Thus, we conducted this meta-analysis to summarize the possible association between RAGE -374T/A polymorphism and DR risk. METHOD: We searched all relevant articles on the association between RAGE -374T/A polymorphism and DR risk from PubMed, Cochrane Library, ScienceDirect, Wanfang, VIP and Chinese National Knowledge Infrastructure (CNKI) web databases up to August 2016. Odds ratio (OR) with 95% confidence interval (CI) were calculated to assess those associations. All analyses were performed using the Review Manager software. RESULTS: Nine case-control studies, including 1,705 DR cases and 2,236 controls were enrolled, and the results showed that the A allele of RAGE -374T/A polymorphism was significantly associated with increased DR risk in dominant model (TA/AA vs. TT: OR=1.22, 95CI 1.05-1.41, p=0.006) and heterozygote model (TA vs. TT: OR=1.26, 95CI 1.07-1.47, p=0.005). The subgroup analysis by ethnicity showed that significantly increased DR risk was found in both Asian and Caucasian populations. CONCLUSION: This meta-analysis reveals that the A allele of RAGE 374T/A polymorphism probably increase DR risk. PMID- 29451662 TI - What clinical, functional, and psychological factors before treatment are predictors of poor quality of life in cancer patients at the end of chemotherapy? AB - OBJECTIVE: To correlate physical activity level (PAL), functional capacity and psychological state with quality of life (QoL) in cancer patients undergoing chemotherapy (CT). METHOD: Observational cohort study. Patients (n=121) with any primary cancer site with indications of chemotherapy with palliative or curative intent were evaluated at three moments: 1) patient admission (week 0), before chemotherapy; 2) week 8; 3) end of CT. Data were collected regarding QoL, PAL, clinical data, functional capacity (short walking distance test, sitting-rising test, isometric manual gripping force), and anxiety and depression tests. RESULTS: There was significant improvement at the end of CT for: level of physical activity; walk test (> 500 meters); sitting-rising test (> 20x). There was a significant reduction in the prevalence of moderate/severe depression. The prevalence of high QoL showed a significant increase in evaluation 3 (42.4% vs. 40.0% vs. 59.2%, p=0.02). Education up to high school level, low PAL, walking < 300 meters, sitting and rising < 20 times, having depression (moderate to severe) and QoL that was not high at the start of treatment (week 0) all proved to be risk factors for low quality of life at week 16. Conversely, early staging, curative intent chemotherapy and low-grade symptoms were shown to be protective factors. CONCLUSION: Performing less than 20 movements in the sitting-rising test and low PAL at the start of chemotherapy represent independent risk factors for low quality of life at the end of chemotherapy. PMID- 29451663 TI - The analysis on the expression of gasotransmitters in early trauma patients. AB - OBJECTIVE: Nitric oxide (NO), carbon monoxide (CO) and hydrogen sulfide (H2S) were endogenously-generated molecules gas. They owned important biological activity and participated in many pathophysiological processes. This study aimed to examine the levels of three gasotransmitters in the early phase of trauma patients. METHOD: Blood samples were collected from 60 trauma patients and ten healthy volunteers. Concentration of serum iNOS and HO-1 were analyzed by enzyme linked immunosorbent assay and plasma H2S was determined by colorimetric method. Meanwhile, the occurrence of multiple organ dysfunction syndrome (MODS) was also monitored. RESULTS: The levels of iNOS, HO-1 and endogenous H2S in the patients group were significantly different from the healthy control group, and the difference was more obvious with the increase of ISS score. iNOS levels were positively correlated with ISS scores and blood lactic acid values, and HO-1 and endogenous H2S were negatively correlated with ISS scores and blood lactic acid values. Of 60 trauma patients, eight (13.33%) developed MODS. The level of iNOS in the MODS group was higher than that in non-MODS group, while HO-1 and H2S were significant lower in the MODS group. CONCLUSION: The three gasotransmitters participated in systemic inflammatory responses during early trauma and could be used as important indicators for trauma severity. Their measurements were meaningful for evaluating the severity and prognosis of trauma. PMID- 29451664 TI - Update on antiphospholipid antibody syndrome. AB - Antiphospholipid syndrome (APS) is an autoimmune disease characterized by antiphospholipid antibodies (aPL) associated with thrombosis and/or pregnancy morbidity. Most APS events are directly related to thrombotic events, which may affect small, medium or large vessels. Other clinical features like thrombocytopenia, nephropathy, cardiac valve disease, cognitive dysfunction and skin ulcers (called non-criteria manifestations) add significant morbidity to this syndrome and represent clinical situations that are challenging. APS was initially described in patients with systemic lupus erythematosus (SLE) but it can occur in patients without any other autoimmune disease. Despite the autoimmune nature of this syndrome, APS treatment is still based on anticoagulation and antiplatelet therapy. PMID- 29451665 TI - Mirror therapy: A potential intervention for pain management. AB - The consequences of chronic pain and associated disabilities to the patient and to the health care system are well known. Medication is often the first treatment of choice for chronic pain, although side effects and high costs restrict long term use. Inexpensive, safe and easy to self-administer non-pharmacological therapies, such as mirror therapy, are recommended as adjuncts to pain treatment. The purpose of this review is to describe the principles of use of mirror therapy so it can be incorporated into a health care delivery. The physiological rationale of mirror therapy for the management of pain and the evidence of clinical efficacy based on recent systematic reviews are also discussed. Mirror therapy, whereby a mirror is placed in a position so that the patient can view a reflection of a body part, has been used to treat phantom limb pain, complex regional pain syndrome, neuropathy and low back pain. Research evidence suggests that a course of treatment (four weeks) of mirror therapy may reduce chronic pain. Contraindications and side effects are few. The mechanism of action of mirror therapy remains uncertain, with reintegration of motor and sensory systems, restored body image and control over fear-avoidance likely to influence outcome. The evidence for clinical efficacy of mirror therapy is encouraging, but not yet definitive. Nevertheless, mirror therapy is inexpensive, safe and easy for the patient to self-administer. PMID- 29451666 TI - Pilates for breast cancer: A systematic review and meta-analysis. AB - INTRODUCTION: Breast cancer is the leading type of cancer causing death in women worldwide. The incidence of the disease is expected to grow worldwide due to the aging of the population and risk factors related to lifestyle behaviors. Considering the lifestyle of women with breast cancer before or after surgery, pilates exercise may be a complementary intervention additionally to standard treatment. OBJECTIVE: To analyze the efficacy of pilates compared to other exercises and to no exercise for women with breast cancer diagnosis. METHOD: We searched Medline via Pubmed, Embase via Ovid, Amed via EBSCO, Biosis via Ovid, Lilacs and the Cochrane Library for relevant publications until March 2017. The keywords used were pilates and "breast cancer," and only randomized controlled trials were included. Critical appraisal was done using Risk of Bias Tool and GRADE score for assessing the quality of evidence. RESULTS: A total of five studies were included in our review. Our results demonstrate that pilates or home based exercises are better than no exercise in each individual study. We observed significant improvements in the pilates groups compared to home-based exercises. Additionally, in the individual studies, we observed improvements in range of motion, pain and fatigue. CONCLUSION: The evidence shows that pilates or home based exercise should be encouraged to women with breast cancer. PMID- 29451667 TI - Approach to concurrent coronary and carotid artery disease: Epidemiology, screening and treatment. AB - The concomitance between coronary artery disease and carotid artery disease is known and well documented. However, it is a fact that, despite the screening methods for these conditions and the advances in surgical treatment, little has been achieved in terms of reducing the risk of complications in the perioperative period. Publications are scarce, being mostly composed of reports or case series. There is little agreement on the best initial therapeutic approach (myocardial versus carotid revascularization) or the best technique to be used (surgery with or without extracorporeal circulation, hybrid treatments, etc.). The authors performed a review of the evidence in this clinical scenario, raising pragmatic questions that help in the therapeutic decision. PMID- 29451668 TI - Comparison between early and delayed facial nerve decompression in traumatic facial nerve paralysis - A retrospective study. AB - Purpose To study the intraoperative findings in case of early and delayed decompression of facial nerve paralysis and compare their results. Methods Retrospective data analysis of 23 cases of longitudinal temporal bone fracture with House-Brackmann grade V and VI facial nerve paralysis. All cases were thoroughly evaluated and underwent facial nerve decompression through the transmastoid approach. All cases were under regular follow-up till the date of manuscript submission. Results Clinical improvement of the facial nerve function was observed for early vs. delayed facial nerve decompression. In the early decompression group, facial nerve function improved to grade II in eight cases (80%) and grade III in two cases (20%), whereas in the delayed decompression group it improved to grade II in one case (7.70%), grade III in four cases (30.76%), grade IV in seven cases (53.84%), and grade V in one case (7.70%). Conclusions Early decompression of facial nerve provides better results than delayed decompression because it enables early expansion of the nerve. PMID- 29451669 TI - Prosodic parameters of reading in 2nd to 5th grade students. AB - Purpose Characterize and compare melodic variation and reading speed and verify their evolution throughout the development of schooling. Methods The reading of 78 Elementary School (2nd to 5th grade) students was analyzed using the Praat program with regards to the parameters of melodic variation (F0) and reading speed (Duration). Statistical measures (mean and standard deviation) were taken and the Student's t-test was applied at significance level of 5%. Results Melodic variation and reading speed increased as schooling progressed, especially during 5th grade. Conclusion Melodic variation increases as schooling progresses, mainly during 5th grade. First minute of reading analysis is sufficient to assess reading speed, not being necessary to analyze the full text. PMID- 29451670 TI - 'It's a traumatic illness, traumatic to witness': a qualitative study of the experiences of bereaved family caregivers of patients with cutaneous T-cell lymphoma. AB - BACKGROUND: Cutaneous T-cell lymphomas (CTCL) are rare cancers, which can be difficult to diagnose, are incurable and adversely affect quality of life, particularly in advanced disease. Families often provide care, but little is known about their experiences or needs while caring for their relative with advanced disease or in bereavement. OBJECTIVES: To explore the experiences of bereaved family caregivers of patients with CTCL. METHODS: Single, semi structured qualitative interviews were conducted with bereaved family caregivers of patients with CTCL recruited via a supra-regional CTCL clinic. Transcribed interviews were analysed thematically, focusing on advanced disease, the approach of death and bereavement. RESULTS: Fifteen carers of 11 deceased patients participated. Experiences clustered under four themes: (1) complexity of care and medical intervention; (2) caregiver roles in advanced CTCL; (3) person-centred vs. organization-centred care in advanced CTCL and (4) knowing and not knowing: reflections on dying, death and bereavement. Caregivers often had vivid recollections of the challenges of caring for their relative with advanced CTCL and some took on quasi-professional roles as a result. Advanced disease made high demands on both organizational flexibility and family resources. For many caregivers, seeing disease progression was a prolonged and profoundly traumatic experience. The extent to which they were prepared for their relative's death and supported in bereavement was highly variable. Sub-themes within each theme provide more detail about caregiver experiences. CONCLUSIONS: Family caregivers should be considered part of the wider healthcare team, acknowledging their multiple roles and the challenges they encounter in looking after their relative with CTCL as the disease progresses. Their experiences highlight the importance of organizational flexibility and of good communication between healthcare providers in advanced CTCL.

AB - Contents Summary 37 I. Introduction 37 II. Predictions for metabolic kinetics 38 III. Kinetics of net photosynthesis 38 IV. Kinetics of plant growth 40 V. Hypotheses for higher-level kinetic decoupling 41 VI. Conclusions 42 Acknowledgements 42 References 42 SUMMARY: Understanding how temperature influences the scaling of physiological rates through levels of biological organization is critical for predicting plant responses to climate. Metabolic theory predicts that many rates increase exponentially with temperature following an activation energy (E) of 0.32 eV for photosynthesis. Here, I evaluate this prediction for net photosynthesis and organ, individual, and ecosystem growth. Observed E for photosynthesis varied widely but was not statistically different from predictions, while E for organs was greater than predicted, and E for individuals and ecosystems only weakly characterized temperature responses. I review several hypotheses that may underlie these results. Understanding how multiple rate-limiting processes coalesce into a single E that characterizes metabolic responses to temperature, and how to best estimate E from unimodal data, remain important challenges. PMID- 29451672 TI - Predictors of persistent prescription opioid analgesic use among people without cancer in Australia. AB - AIMS: To identify patterns of opioid analgesic use and determine predictors of persistent opioid use among people without cancer. METHODS: A population-based cohort study of Australians initiating prescription opioids from July 2013 to December 2015 was conducted using data from a random 10% sample of people who accessed medicines through Australia's Pharmaceutical Benefits Scheme. A 12-month retrospective period was used to define opioid initiation, exclude people with cancer and determine comorbidities. Persistent use over 12 months since initiation was identified through group-based trajectory modelling. Odds ratios (OR) and 95% confidence intervals (CIs) for predictors of opioid persistence were estimated using logistic regression. RESULTS: The cohort consisted of 431 963 people without cancer who initiated opioids. A total of 11 323 (2.6%) persistent opioid users were identified. Predictors of persistence included initiation with transdermal formulations (OR 4.2, 95% CI 3.9-4.5), or initiation with total oral morphine equivalents (OME) >= 750 mg (3.7, 3.3-4.1), having depression (1.6, 1.5 1.7) or psychotic illness (2.0, 1.9-2.2). Previous dispensing of paracetamol (2.0, 1.9-2.1), pregabalin (2.0, 1.8-2.1) and benzodiazepines (1.53, 1.4-1.6) predicted persistence. Compared to people aged 18-44 years, those >=75 years were 2.5 (2.3-2.6) times more likely to be persistent users. CONCLUSIONS: Patient specific characteristics (older age, prior history of mental health comorbidities and use of non-opioid analgesics) and prescriber choice of initial opioid (transdermal formulation and higher total OMEs) were found to strongly predict persistent use. This information may help prescribers target monitoring and early intervention efforts in order to prevent harms associated with the long-term use of opioids. PMID- 29451681 TI - Verification of a physiologically based pharmacokinetic model of ritonavir to estimate drug-drug interaction potential of CYP3A4 substrates. AB - Ritonavir is one of several ketoconazole alternatives used to evaluate strong CYP3A4 inhibition potential in clinical drug-drug interaction (DDI) studies. In this study, four physiologically based pharmacokinetic (PBPK) models of ritonavir as an in vivo time-dependent inhibitor of CYP3A4 were created and verified for oral doses of 20, 50, 100 and 200 mg using the fraction absorbed (Fa ) and oral clearance (CLoral ) values reported in the literature, because transporter and CYP enzyme reaction phenotyping data were not available. The models were used subsequently to predict and compare the magnitude of the AUC increase in nine reference DDI studies evaluating the effect of ritonavir at steady-state on midazolam (CYP3A4 substrate) exposure. Midazolam AUC and Cmax ratios were predicted within 2-fold of the respective observations in seven studies. Simulations of the hepatic and gut CYP3A4 abundance after multiple oral dosing of ritonavir indicated that a 3-day treatment with ritonavir 100 mg twice daily is sufficient to reach maximal CYP3A4 inhibition and subsequent systemic exposure increase of a CYP3A4 substrate, resulting in the reliable estimation of fm,CYP3A4 . The ritonavir model was submitted as part of the new drug application for Kisqali(r) (ribociclib) and accepted by health authorities. PMID- 29451682 TI - Metabolic regulation of leukocyte motility and migration. AB - Dynamic reorganization of the cytoskeleton is essential for numerous cellular processes including leukocyte migration. This process presents a substantial bioenergetic challenge to migrating cells as actin polymerization is dependent on ATP hydrolysis. Hence, migrating cells must increase ATP production to meet the increased metabolic demands of cytoskeletal reorganization. Despite this long standing evidence, the metabolic regulation of leukocyte motility and trafficking has only recently begun to be investigated. In this review, we will summarize current knowledge of the crosstalk between cell metabolism and the cytoskeleton in leukocytes, and discuss the concept that leukocyte metabolism may reprogram in response to migratory stimuli and the different environmental cues received during recirculation ultimately regulating leukocyte motility and migration. PMID- 29451683 TI - Prenatal diagnosis of anomalous origin of pulmonary artery. AB - BACKGROUND: Anomalous origin of the pulmonary arteries is a rare congenital pulmonary vascular malformation that includes unilateral absence of the pulmonary artery (UAPA), anomalous origin of unilateral pulmonary artery (AOPA), and left pulmonary artery sling (LPAS). METHODS: We analyze 15 cases of fetal pulmonary artery abnormalities from 2011 to 2017, detected via prenatal ultrasound at our center. RESULTS: The 15 cases include UAPA (5), AOPA (6), and LPAS (4). Of the UAPA cases, 2 had pulmonary atresia and 3 had pulmonary artery stenosis. In 5 cases, the descending aorta issued collateral vessels to the left lung. Of the AOPA cases, 2 had left pulmonary artery abnormalities originating in the ascending aorta and 4 showed right pulmonary artery abnormalities originating in the ascending aorta. Of the LPAS cases, 2 were type IA, 1 was type IIA, and 1 was type IIB. Two of the LPAS were associated with right lung dysplasia. CONCLUSION: Abnormal origin of the pulmonary artery has a characteristic ultrasonographic appearance. The branch of the pulmonary artery cross section can provide important clues to the diagnosis of abnormal pulmonary artery origin. Pulmonary artery abnormalities are often associated with pulmonary atresia or stenosis. PMID- 29451684 TI - Intracellular pharmacokinetics of gemcitabine, its deaminated metabolite 2',2' difluorodeoxyuridine and their nucleotides. AB - AIMS: Gemcitabine (2',2'-difluoro-2'-deoxycytidine; dFdC) is a prodrug that has to be phosphorylated within the tumour cell to become active. Intracellularly formed gemcitabine diphosphate (dFdCDP) and triphosphate (dFdCTP) are considered responsible for the antineoplastic effects of gemcitabine. However, a major part of gemcitabine is converted into 2',2'-difluoro-2'-deoxyuridine (dFdU) by deamination. In the cell, dFdU can also be phosphorylated to its monophosphate (dFdUMP), diphosphate (dFdUDP) and triphosphate (dFdUTP). In vitro data suggest that these dFdU nucleotides might also contribute to the antitumour effects, although little is known about their intracellular pharmacokinetics (PK). Therefore, the objective of the present study was to gain insight into the intracellular PK of all dFdC and dFdU nucleotides formed during gemcitabine treatment. METHODS: Peripheral blood mononuclear cell (PBMC) samples were collected from 38 patients receiving gemcitabine, at multiple time points after infusion. Gemcitabine, dFdU and their nucleotides were quantified in PBMCs. In addition, gemcitabine and dFdU plasma concentrations were monitored. The individual PK parameters in plasma and in PBMCs were determined. RESULTS: Both in plasma and in PBMCs, dFdU was present in higher concentrations than gemcitabine [mean intracellular area under the concentration-time curve from time zero to 24 h (AUC0-24 h ) 1650 vs. 95 MUM*h]. However, the dFdUMP, dFdUDP and dFdUTP concentrations in PBMCs were much lower than the dFdCDP and dFdCTP concentrations. The mean AUC0-24 h for dFdUTP was 312 MUM*h vs. 2640 MUM*h for dFdCTP. CONCLUSIONS: The study provides the first complete picture of all nucleotides that are formed intracellularly during gemcitabine treatment. Low intracellular dFdU nucleotide concentrations were found, which calls into question the relevance of these nucleotides for the cytotoxic effects of gemcitabine. PMID- 29451685 TI - A quantitative LC/MSMS method for determination of edoxaban, a Xa inhibitor and its pharmacokinetic application in patients after total knee arthroplasty. AB - Edoxaban was extracted from human plasma by simple protein precipitation with acetonitrile, followed by quantitative determination using a liquid chromatography-mass spectrometry method. The recoveries of edoxaban and the internal standard (ticlopidine) from human plasma were >85%, and the within- and between-day coefficients of variation were within 15%. The limit of quantification in human plasma was 1 ng/mL. The concentration of edoxaban in blood decreased at room temperature, but remained unchanged for 1 week at 4 degrees C. On the other hand, the concentration in plasma at both -20 and -80 degrees C remained unchanged for 5 months. These results indicated that blood samples should be centrifuged immediately or stored at 4 degrees C, and that plasma samples should be stored below -20 degrees C until analysis. This method was applied to human plasma obtained from four patients after total knee arthroplasty. Analysis of edoxaban pharmacokinetics demonstrated an absorption time lag of 4h, a maximum concentration of 110 +/- 26 ng/mL and an oral clearance of 37 +/- 16 L/h. The analytical methods established in this study will be suitable for determining the concentrations of edoxaban in human plasma. PMID- 29451686 TI - An iminium ion metabolite hampers the production of the pharmacologically active metabolite of a multikinase inhibitor KW-2449 in primates: irreversible inhibition of aldehyde oxidase and covalent binding with endogenous proteins. AB - We previously reported that KW-2449, (E)-1-{4-[2-(1H-Indazol-3 yl)vinyl]benzoyl}piperazine, a novel multikinase inhibitor developed for the treatment of leukemia patients, was oxidized to an iminium ion intermediate by monoamine oxidase B (MAO-B) and then converted to its oxo-piperazine form (M1) by aldehyde oxidase (AO). However, it was found that the significant decrease in the pharmacologically active metabolite M1 following repeated administration of KW 2449 in primates might hamper the effectiveness of the drug. The mechanism underlying this phenomenon was investigated and it was found that the AO activity was inhibited in a time-dependent manner in vitro under the co-incubation of KW 2449 and MAO-B, while neither KW-2449 nor M1 strongly inhibited MAO-B or AO activity. These results clearly suggest that MAO-B catalysed iminium ion metabolite inhibited AO, prompting us to investigate whether or not the iminium ion metabolite covalently binds to endogenous proteins, as has been reported with other reactive metabolites as a cause for idiosyncratic toxicity. The association of the radioactivity derived from 14 C-KW-2449 with endogenous proteins both in vivo and in vitro was confirmed and it was verified that this covalent binding was inhibited by the addition of sodium cyanide, an iminium ion-trapping reagent, and pargyline, a MAO-B inhibitor. These findings strongly suggest that the iminium ion metabolite of KW-2449 is highly reactive in inhibiting AO irreversibly and binding to endogenous macromolecules covalently.

PMID- 29451689 TI - Barriers to accessing palliative care for pediatric patients with cancer: A review of the literature. AB - Although many of the 16,000 children in the United States diagnosed who are with cancer each year could benefit from pediatric palliative care, these services remain underused. Evidence regarding the barriers impeding access to comprehensive palliative care is dispersed in the literature, and evidence specific to pediatric oncology remains particularly sparse. The purpose of the current review was to synthesize the existing literature regarding these barriers and the strategies offered to address them. The authors completed a literature search using the PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Web of Science databases. In total, 71 articles were reviewed. Barriers to accessing pediatric palliative care were categorized according to the 4 levels of a modified socioecological model (ie, barriers related to policy/payment, health systems, organizations, and individuals). Major themes identified at each level included: 1) the lack of consistent and adequate funding mechanisms at the policy/payment level, 2) the lack of pediatric palliative care programs and workforce at the health systems level, 3) difficulties integrating palliative care into existing pediatric oncology care models at the organizational level, and 4) the lack of knowledge about pediatric palliative care, discomfort with talking about death, and cultural differences between providers and patients and their families at the individual level. Recommendations to address each of the barriers identified in the literature are included. Cancer 2018;124:2278-88. (c) 2018 American Cancer Society.

AB - : Cardiovascular disease (CVD) remains the largest cause of mortality worldwide, and there is a clear gender gap in disease occurrence, with men being predisposed to earlier onset of CVD, including atherosclerosis and hypertension, relative to women. Oestrogen may be a driving factor for female-specific cardioprotection, though androgens and sex chromosomes are also likely to contribute to sexual dimorphism in the cardiovascular system (CVS). Many GPCR-mediated processes are involved in cardiovascular homeostasis, and some exhibit clear sex divergence. Here, we focus on the G protein-coupled oestrogen receptor, endothelin receptors ETA and ETB and the eicosanoid G protein-coupled receptors (GPCRs), discussing the evidence and potential mechanisms leading to gender dimorphic responses in the vasculature. The use of animal models and pharmacological tools has been essential to understanding the role of these receptors in the CVS and will be key to further delineating their sex-specific effects. Ultimately, this may illuminate wider sex differences in cardiovascular pathology and physiology. LINKED ARTICLES: This article is part of a themed section on Molecular Pharmacology of GPCRs.

AB - BACKGROUND: Facial morphoea is a chronic inflammatory skin disorder, typically presenting in childhood and adolescence, which can be disfiguring, and which has been suggested to cause mild-to-moderate impairment in quality of life. OBJECTIVES: To explore the everyday experiences of children with facial morphoea by examining the psychosocial impact of living with facial morphoea and how children and their families manage its impact. METHODS: We used a qualitative, social constructionist approach involving focus groups, in-depth interviews and drawing activities with 10 children with facial morphoea aged 8-17 years and 13 parents. Interpretive thematic analysis was utilized to examine the data. RESULTS: Children and parents reported on the stress of living with facial morphoea, which was related to the lack of knowledge about facial morphoea and the extent to which they perceived themselves as different from others. Self perceptions were based on the visibility of the lesion, different phases of life transitions and the reactions of others (e.g. intrusive questioning and bullying). Medication routines, and side-effects such as weight gain, added to the stress experienced by the participants. To manage the impact of facial morphoea, children and their parents used strategies to normalize the experience by hiding physical signs of the illness, constructing explanations about what 'it' is, and by connecting with their peers. CONCLUSIONS: Understanding what it is like to live with facial morphoea from the perspectives of children and parents is important for devising ways to help children with the disorder achieve a better quality of life. Healthcare providers can help families access resources to manage anxiety, deal with bullying and construct adequate explanations of facial morphoea, in addition to providing opportunities for peer support. PMID- 29451695 TI - Decreased early mortality associated with the treatment of acute myeloid leukemia at National Cancer Institute-designated cancer centers in California. AB - BACKGROUND: To the authors' knowledge, few population-based studies to date have evaluated the association between location of care, complications with induction therapy, and early mortality in patients with acute myeloid leukemia (AML). METHODS: Using linked data from the California Cancer Registry and Patient Discharge Dataset (1999-2014), the authors identified adult (aged >=18 years) patients with AML who received inpatient treatment within 30 days of diagnosis. A propensity score was created for treatment at a National Cancer Institute designated cancer center (NCI-CC). Inverse probability-weighted, multivariable logistic regression models were used to determine associations between location of care, complications, and early mortality (death <=60 days from diagnosis). RESULTS: Of the 7007 patients with AML, 1762 (25%) were treated at an NCI-CC. Patients with AML who were treated at NCI-CCs were more likely to be aged <=65 years, live in higher socioeconomic status neighborhoods, have fewer comorbidities, and have public health insurance. Patients treated at NCI-CCs had higher rates of renal failure (23% vs 20%; P = .010) and lower rates of respiratory failure (11% vs 14%; P = .003) and cardiac arrest (1% vs 2%; P = .014). After adjustment for baseline characteristics, treatment at an NCI-CC was associated with lower early mortality (odds ratio, 0.46; 95% confidence interval, 0.38-0.57). The impact of complications on early mortality did not differ by location of care except for higher early mortality noted among patients with respiratory failure treated at non-NCI-CCs. CONCLUSIONS: The initial treatment of adult patients with AML at NCI-CCs is associated with a 53% reduction in the odds of early mortality compared with treatment at non-NCI-CCs. Lower early mortality may result from differences in hospital or provider experience and supportive care. Cancer 2018;124:1938-45. (c) 2018 American Cancer Society. PMID- 29451696 TI - Randomized phase 2 trial of pemetrexed, pemetrexed/bevacizumab, and pemetrexed/carboplatin/bevacizumab in patients with stage IIIB/IV non-small cell lung cancer and an Eastern Cooperative Oncology Group performance status of 2. AB - BACKGROUND: The best treatment for patients with advanced non-small cell lung cancer (NSCLC) and a poor performance status is not well defined. In this phase 2 trial, patients were randomized to receive treatment with either single-agent pemetrexed or 1 of 2 combination regimens. METHODS: Patients with newly diagnosed, histologically confirmed nonsquamous NSCLC and an Eastern Cooperative Oncology Group (ECOG) performance status of 2 were stratified by age and serum albumin level and were randomized (1:1:1) to 1 of 3 regimens: pemetrexed (arm 1), pemetrexed and bevacizumab (arm 2), or pemetrexed, carboplatin, and bevacizumab (arm 3). The response to treatment was assessed every 2 cycles; responding and stable patients continued treatment until progression or unacceptable toxicity. RESULTS: One hundred seventy-two patients were randomized, 162 patients began the study treatment, and 146 patients completed 2 cycles and were evaluated for their response. The median progression-free survival (PFS) was 2.8 months in arm 1, 4.0 months in arm 2, and 4.8 months in arm 3. The overall response rates were 15% in arm 1, 31% in arm 2, and 44% in arm 3. The overall survival was similar in the 3 treatment arms. All 3 regimens were relatively well tolerated. Patients receiving bevacizumab had an increased incidence of hypertension, proteinuria, and bleeding episodes, but most events were mild or moderate. CONCLUSIONS: All 3 regimens were feasible for patients with advanced NSCLC and an ECOG performance status of 2. The addition of bevacizumab to pemetrexed increased the overall response rate. The efficacy of pemetrexed/carboplatin/bevacizumab (median PFS, 4.8 months) approached the prespecified study PFS goal of 5 months.

PMID- 29451698 TI - The ketogenic diet is effective for refractory epilepsy associated with acquired structural epileptic encephalopathy. AB - AIM: Ketogenic diet therapies have proven efficacy for refractory epilepsy. There are many reports of their use in the genetic developmental and epileptic encephalopathies; however, little attention has been paid as to whether the diet is also effective in individuals with an acquired structural aetiology. We observed remarkable efficacy of the diet in two patients with hypoxic-ischaemic encephalopathy. We then analysed our cases with refractory structural epilepsies of acquired origin to characterize their response to the ketogenic diet. METHOD: The classical ketogenic diet was implemented with dietary ratios of 3:1 to 4.4:1. Seizure frequency at 1 month, 3 months, 6 months, 1 year, and 2 years was ascertained. A responder was defined as greater than 50% seizure reduction compared to baseline. RESULTS: Seven of the nine patients were responders at 3 months. INTERPRETATION: Somewhat surprisingly we found that the ketogenic diet was effective in patients with a developmental and epileptic encephalopathy due to an acquired structural aetiology. This cohort may not be routinely considered for the ketogenic diet because of their structural and acquired, rather than genetic, basis. The ketogenic diet should be considered early in the management of patients with acquired structural encephalopathies as it can improve seizure control with the potential to improve developmental outcome. WHAT THIS PAPER ADDS: The ketogenic diet was effective in children with epilepsy associated with an acquired structural aetiology.

AB - AIM: To develop and validate a disease-specific parent proxy and child quality of life (QoL) measure for patients aged 2 to 18 years surviving cerebral sinovenous thrombosis (CSVT) and arterial ischaemic stroke (AIS). METHOD: Utilizing qualitative and quantitative methods, we developed a 75-item Pediatric Stroke Quality of Life Measure (PSQLM) questionnaire. We mailed the PSQLM and a standardized generic QoL measure, Pediatric Quality of Life Inventory (PedsQL), to 353 families. Stroke type, age at stroke, and neurological outcome on the Pediatric Stroke Outcome Measure were documented. We calculated the internal consistency, validity, and reliability of the PSQLM. RESULTS: The response rate was 29%, yielding a sample of 101 patients (mean age 9y 9mo [SD 4.30]; 69 AIS [68.3%], 32 CSVT [31.7%]). The internal consistency of the PSQLM was high (Cronbach's alpha=0.94-0.97). Construct validity for the PSQLM was moderately strong (r=0.3-0.4; p<0.003) and, as expected, correlation with the PedsQL was moderate, suggesting the PSQLM operationalizes QoL distinct from the PedsQL. Test retest reliability at 2 weeks was very good (intraclass correlation coefficient [ICC] 0.85-0.95; 95% confidence interval 0.83-0.97) and good agreement was established between parent and child report (ICC 0.63-0.76). INTERPRETATION: The PSQLM demonstrates sound psychometric properties. Further research will seek to increase its clinical utility by reducing length and establishing responsiveness for descriptive and longitudinal evaluative assessment. WHAT THIS PAPER ADDS: A pediatric stroke-specific quality of life (QoL) measurement tool for assessments based on perceptions of importance and satisfaction. Moderate-to-high reliability and validity established for a new clinical scale evaluating QoL among children with stroke. Perceived QoL measured using the Pediatric Stroke Quality of Life Measure appears lower in children with neurological impairment.

PMID- 29451701 TI - Phase 1b study of pasireotide, everolimus, and selective internal radioembolization therapy for unresectable neuroendocrine tumors with hepatic metastases. AB - BACKGROUND: Neuroendocrine tumors (NETs) metastasize to the liver. Everolimus and selective internal radioembolization (SIRT) are approved treatments. Pasireotide is a somatostatin analogue with an affinity for somatostatin receptors 1, 2, 3, and 5. Everolimus and pasireotide may potentiate SIRT radiosensitization and inhibit rebound angiogenesis. This study evaluated the safety of pasireotide, everolimus, and SIRT. METHODS: This 3 + 3 phase 1 trial evaluated 3 dose levels of everolimus (2.5, 5, and 10 mg/day), pasireotide (600 MUg twice daily), and SIRT (SIR-Spheres dose on days 9 and 37). Eligibility criteria included well or moderately differentiated NETs, bilobar liver metastases, and progression on long acting octreotide. Toxicities and responses were evaluated with the Common Terminology Criteria for Adverse Events and the Response Evaluation Criteria in Solid Tumors (version 1.1). Dose-limiting toxicities (DLTs) were defined in the first 28 days. Correlative markers-angiopoietin 1, angiopoietin 2, basic fibroblast growth factor, collagen V, insulin-like growth factor binding protein 1, insulin-like growth factor binding protein 1, interleukin 8, M30, M65, placenta growth factor, and vascular endothelial growth factor receptor 2-were assessed. The Norfolk Quality of Life-Neuroendocrine Tumor Questionnaire was used to assess the quality of life (QOL). RESULTS: Thirteen patients were enrolled; 1 was not evaluable for the primary endpoint. Eleven patients had well differentiated tumors. The primary sites included small bowel (4), pancreas (3), lung (2), colon (1), gastric (1), and unknown primary (2) were unknown. Four had liver-only disease; 12 completed the planned treatment. No DLTs were observed. There was no treatment-related mortality. The most common toxicity was hyperglycemia. Clinically significant liver toxicity was not observed. One patient had liver progression. QOL improved on treatment. The median progression free survival and overall survival were 18.6 and 46.3 months, respectively. CONCLUSIONS: The recommended phase 2 dose of everolimus is 10 mg daily in combination with pasireotide and SIRT. The regimen is well tolerated. Preliminary activity appears promising.

AB - AIM: To determine the incidence of common adverse events after botulinum toxin A (BoNT-A) injections in children with cerebral palsy (CP) and to identify whether the severity of CP influences the incidence of adverse events. METHOD: This was an observational study of patients attending a BoNT-A clinic at a tertiary paediatric hospital (2010-2014). Data examined included procedural adverse events at the time of injection and at follow-up. Systemic adverse events were defined as lower respiratory tract illnesses, generalized weakness, dysphagia, and death. Severity of CP was categorized by the Gross Motor Function Classification System (GMFCS). The relationships between GMFCS and adverse events were analysed using negative binomial regression models. RESULTS: In total, 591 children underwent 2219 injection episodes. Adverse events were reported during the procedure (130 [6%] injection episodes) and at follow-up (492 [22%] injection episodes). There were significantly increased rates of systemic adverse events in injection episodes involving children in GMFCS level IV (incidence rate ratio [IRR] 3.92 [95% confidence interval] 1.45-10.57]) and GMFCS level V (IRR 7.37 [95% confidence interval 2.90-18.73]; p<0.001). INTERPRETATION: Adverse events after BoNT-A injections are common but mostly mild and self-limiting. Children in GMFCS levels IV and V are at increased risk of systemic adverse events. The relationship between CP severity and BoNT-A adverse events is complex and further research is required to better understand this relationship. WHAT THIS PAPER ADDS: Adverse events reported at the time of botulinum toxin A injection occurred in 6% of injection episodes. Adverse events were reported at follow-up in 22% of injection episodes. Children in Gross Motor Function Classification System (GMFCS) levels IV and V have increased rates of systemic adverse events. Children in GMFCS levels IV and V report less local weakness and pain. PMID- 29451703 TI - Mechanisms of imidazoline I2 receptor agonist-induced antinociception in rats: involvement of monoaminergic neurotransmission. AB - BACKGROUND AND PURPOSE: Although the antinociceptive efficacies of imidazoline I2 receptor agonists have been established, the exact post-receptor mechanisms remain unknown. This study tested the hypothesis that monoaminergic transmission is critical for I2 receptor agonist-induced antinociception. EXPERIMENTAL APPROACH: von Frey filaments were used to assess antinociceptive effects of two I2 receptor agonists, 2-BFI and CR4056 on chronic constriction injury (CCI) induced neuropathic pain or complete Freund's adjuvant (CFA)-induced inflammatory pain in rats. Rectal temperature was measured to assess hypothermic effects of 2 BFI. A two-lever drug discrimination paradigm in which rats were trained to discriminate 5.6 mg.kg-1 2-BFI (i.p.) from its vehicle was used to examine the discriminative stimulus effects of 2-BFI. In each experiment, pharmacological mechanisms were investigated by combining 2-BFI or CR4056 with various pharmacological manipulations of the monoaminergic system including selective reuptake inhibition, monoamine depletion and monoamine receptor antagonism. KEY RESULTS: In the CCI model, selective reuptake inhibitors of 5-HT (fluoxetine) or noradrenaline (desipramine), but not dopamine (GBR12909), enhanced 2-BFI-induced antinociception. Selective depletion of 5-HT or noradrenaline almost abolished 2 BFI-induced antinociception. 5-HT1A , 5-HT2A and alpha1 -adrenoceptor antagonists, but not other monoaminergic antagonists, attenuated 2-BFI and CR4056 induced antinociception in CCI and/or CFA models. However, none of these monoamine receptor antagonists significantly altered 2-BFI-induced hypothermia or discriminative stimulus effects. CONCLUSIONS AND IMPLICATIONS: Antinociception induced by I2 receptor agonists was mediated by serotonergic and noradrenergic mechanisms with 5-HT1A , 5-HT2A and alpha1 -adrenoceptor being particularly important. In contrast, the hypothermic and discriminative stimulus effects of I2 receptor agonists were mediated by distinct, independent mechanisms. PMID- 29451704 TI - MAIT cells and microbial immunity. AB - Mucosal-associated invariant T (MAIT) cells, the most abundant T-cell subset in humans, are increasingly being recognized for their importance in microbial immunity. MAIT cells accumulate in almost every mucosal tissue examined, including the lung, liver and intestinal tract, where they can be activated through T-cell receptor (TCR) triggering as well as cytokine stimulation in response to a host of microbial products. In this review, we specifically discuss MAIT cell responses to bacterial and fungal infections, with a focus on responses that are both MR1-dependent and -independent, the evidence for diversity in MAIT TCR usage in response to discrete microbial products, protective immunity induced by MAIT cells, and MAIT cell antimicrobial functions in the context of these infections.

AB - AIMS: To investigate whether the proven benefits of insulin degludec (IDeg) combined with insulin aspart (IAsp), known as IDegAsp, given twice daily, extend across a wide spectrum of patients with diabetes. MATERIALS AND METHODS: This was a post hoc pooled analysis of 5 phase III randomized, 26-week, open-label, treat to-target trials comparing IDegAsp twice daily (n = 1111) with one of two comparators: premixed insulin (biphasic insulin aspart 30 [BIAsp 30]) twice daily (n = 561) or IDeg once daily + IAsp (n = 136). Patient data were stratified according to baseline glycated haemoglobin (HbA1c) or fasting plasma glucose (FPG) categories, as well as by baseline duration of diabetes or body mass index (BMI) categories. RESULTS: We conducted a meta-analysis of 5 clinical trials: NCT01513590, NCT01009580, NCT01059812, NCT01680341 and NCT01713530. End-of-trial results were broadly consistent, with differences between IDegAsp and comparators observed in phase III trials. HbA1c results were similar for IDegAsp and the comparators in all baseline characteristic (HbA1c, duration of diabetes or BMI) and category groups (number ranges). Significantly lower FPG level was observed with IDegAsp vs comparators in all baseline characteristic and most category groups (excluding FPG <5.5 mmol/L). Significantly lower insulin doses were observed with IDegAsp vs comparators in all baseline characteristic and half of the category groups, and significantly lower rates of confirmed and nocturnal confirmed hypoglycaemia were observed with IDegAsp vs comparators in all baseline variable and category groups. CONCLUSIONS: IDegAsp retains a consistent safety and efficacy profile in patients with different baseline characteristics.

AB - In this study, epimedins A-, B-, and C-, and icariin-rich extracts were simultaneously isolated from Epimedium brevicornu Maxim. through a convenient four-stage process consisting of solvent extraction, macroporous resin column pre concentration, extraction fractionation, and reversed-phase (RP) silica gel column chromatography. Single factor experiments and response surface methodology (RSM) were used to optimize the preparation conditions. In the final products, the purities of epimedins A - C and icariin were 23.04%, 64.50%, 54.92%, and 77.54%, respectively, which will lay a foundation for the further purification of epimedin monomers and full utilization of Epimedium resources. Meanwhile, the osteogenic effects of epimedins A - C were investigated for the first time and compared with that of icariin, which will provide guidance for the clinical applications of Epimedium in the treatment of osteoporosis. PMID- 29451705 TI - Modeling asthma: Pitfalls, promises, and the road ahead. AB - Asthma is a chronic, heterogeneous, and recurring inflammatory disease of the lower airways, with exacerbations that feature airway inflammation and bronchial hyperresponsiveness. Asthma has been modeled extensively via disease induction in both wild-type and genetically manipulated laboratory mice (Mus musculus). Antigen sensitization and challenge strategies have reproduced numerous important features of airway inflammation characteristic of human asthma, notably the critical roles of type 2 T helper cell cytokines. Recent models of disease induction have advanced to include physiologic aeroallergens with prolonged respiratory challenge without systemic sensitization; others incorporate tobacco, respiratory viruses, or bacteria as exacerbants. Nonetheless, differences in lung size, structure, and physiologic responses limit the degree to which airway dynamics measured in mice can be compared to human subjects. Other rodent allergic airways models, including those featuring the guinea pig (Cavia porcellus) might be considered for lung function studies. Finally, domestic cats (Feline catus) and horses (Equus caballus) develop spontaneous obstructive airway disorders with clinical and pathologic features that parallel human asthma. Information on pathogenesis and treatment of these disorders is an important resource.

AB - The present study provides scientific evidence that a new chemical treatment process using calcium phosphate slurry promotes bone regeneration on titanium (Ti) implants. The material's surface modified by the treatment was analyzed using microscopic observation and the bone regeneration efficacy was evaluated both in vitro and in vivo. Formation of a thin hydroxyapatite layer with a thickness of about 50 nm and an increase of surface roughness were confirmed by microscopic observations. Histological evaluation of rat femora implanted with the specimens showed that the areas of the specimens directly attached to bone tissue were significantly more extensive than those implanted with control Ti at 2 and 8 weeks. Likewise, on the treated Ti, ALP activity, osteopontin, osteocalcin, and calcium contents of rat bone marrow stromal cells were significantly higher than on the control Ti. Furthermore, reverse transcription polymerase chain reaction showed greater expression of messenger ribonucleic acid encoding Cbfa1 and collagen type1 on the treated Ti at 2 weeks. Based on these results, we concluded that the new process was effective to enhance the osteoconductivity of Ti. (c) 2018 Wiley Periodicals, Inc.

PMID- 29451709 TI - Shortcomings in the management of undescended testis: guideline intention vs reality and the underlying causes - insights from the biggest German cohort. AB - OBJECTIVES: To assess the implementation of the current guideline and identify potential underlying causes for late surgery in children with undescended testis (UDT) in Germany. UDT is the most common surgical issue in paediatric urology and to avoid malignant degeneration and subfertility current guidelines recommend orchidopexy during the first year of life; however, this seems not to be implemented in practice. PATIENTS AND METHODS: In all, 5 547 patients with cryptorchidism at 16 hospitals nationwide were studied regarding age at orchidopexy between 2003 and 2016. Multivariate analysis was performed to identify factors influencing timing of surgery. Additionally, a survey on knowledge of UDT management was conducted amongst physicians treating boys and final-year medical students. RESULTS: Between 2003 and 2008 only 4% of boys with UDT underwent surgery before the age of 1 year. After the guideline update from 2009, this figure was 5% from 2010 to 2012, and 8% from 2013 to 2016. The presence of a specialised department for paediatric surgery, as well as a high UDT case-to-year ratio positively influenced the timing of orchidopexy. The survey revealed discipline-specific differences in the levels of knowledge about UDT management. One-third of respondents did not know the guideline recommendations and 61% felt insufficiently informed. International comparisons revealed significant differences in the age at surgery of boys with UDT, with Germany and Great Britain ranging in the middle of the field. CONCLUSIONS: Currently, only a small proportion of boys with UDT are operated upon during their first year of life. The level of knowledge in attending physicians remains in need of improvement. This should be actively addressed, i.e. by campaigns and educational programmes. Further studies are needed to investigate the underlying causes of late orchidopexy in UDT.

PMID- 29451712 TI - Lipid-Modifying Effects of Chitosan Supplementation in Humans: A Pooled Analysis with Trial Sequential Analysis. AB - SCOPE: We performed a pooled analysis with trial sequential analysis (TSA) to evaluate the efficacy and safety of chitosan supplementation on serum lipids in humans. METHODS AND RESULTS: Medline, EMBASE, and CENTRAL databases were queried. Impact was expressed as a weighted mean difference (WMD) and 95% confidence interval (CI). Sensitivity analysis was conducted using the leave-one-out method. Statistical heterogeneity, publication bias, TSA, and subgroup analyses were also assessed. Fourteen trials (21 treatment arms) encompassing 1108 participants were suitable for statistical pooling. Chitosan supplementation significantly improved the total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) concentrations in all patients. The WMDs were -0.20 mmol L-1 (95% CI, -0.35 to 0.05; p = 0.009) for TC, and -0.20 mol L-1 (95% CI, -0.26 to -0.15; p = 0.0001) for LDL-C, respectively. TSA demonstrated that the cumulative Z-curve crossed the trial sequential monitoring boundary for benefit providing conclusive evidence for the benefit of chitosan. However, no significant changes were seen with high density lipoprotein cholesterol (HDL-C) and triglycerides. Our findings were robust after sensitivity analyses, and no serious adverse events were reported with chitosan intake. CONCLUSION: Supplementation with chitosan effectively reduces plasma concentrations of TC and LDL-C. Current evidence indicates daily chitosan supplementation as a candidate for therapeutic lipid management strategies. PMID- 29451710 TI - Salvisertin A, a New Hexacyclic Triterpenoid, and Other Bioactive Terpenes from Salvia deserta Root. AB - Using various chromatographic methods, a new hexacyclic triterpenoid, 2beta,3beta,24beta-trihydroxy-12,13-cyclotaraxer-l4-en-28oic acid (1), together with ten known compounds, 2alpha,3alpha,23-trihydroxyurs-12,20(30)-dien-28oic acid (2), 6,7-dehydroroyleanone (3), horminone (4), 7-O-methylhorminone (5), sugiol (6), demethylcryptojaponol (7), 14-deoxycoleon U (8), 5,6-didehydro-7 hydroxy-taxodone (9), ferruginol (10), and dichroanone (11), were isolated from the roots of Salvia deserta. Their structures were identified on the basis of spectroscopic analysis and comparison with the reported data. The individual compounds (1, 3 - 8) were screened for cytotoxic activity, using the sulforhodamine B bioassay (SRB) method. As the results, Compounds 3, 5, and 8 showed cytotoxic potency against A549, MDA-MB-231, KB, KB-VIN, and MCF7 cell lines with IC50 values ranging from 6.5 to 10.2 MUm. PMID- 29451713 TI - Glucose effectiveness is a critical pathogenic factor leading to glucose intolerance and type 2 diabetes: An ignored hypothesis. AB - BACKGROUND: Although the ability of glucose to mediate its own in vivo metabolism is long documented, the quantitative measurement of whole body glucose-mediated glucose disposal at basal insulin levels (glucose effectiveness [GE]), followed the introduction of the Minimal Model intravenous glucose tolerance test technique. METHODS: A literature review, combined with our own studies, of the role of GE in glucose metabolism in normal and "at risk" individuals, was undertaken to determine GE's contribution to glucose homeostasis. RESULTS: GE accounts for ~45% to 65% of glucose disposal in man. A negative association between GE and insulin meditated glucose disposal (Si), is present in normal subjects without a family history of type 2 diabetes mellitus but is absent in normoglycaemic "at risk" relatives with a positive family history of diabetes mellitus. Intracellular GE disposal is mediated by mass action of glucose through the skeletal muscle membrane via facilitated Glut 4 transporters. However, GE is frequently forgotten as a significant contributor to the development of glucose intolerance in "at risk" individuals. Only limited studies have examined the role of a lower GE in such normoglycemic subjects with preexisting mild insulin resistance and beta-cell dysfunction. These studies demonstrate that in "at risk" individuals, an initial low GE is a key contributor and predictor of future glucose intolerance, whereas an initial raised GE is protective against future glucose intolerance. CONCLUSION: In "at risk" individuals, a low GE and genetically determined vulnerable beta-cell function are more critical determinants of future glucose intolerance than their preexisting insulin resistant state.

AB - Skin injuries represent a health problem with consequences in terms of morbidity, disability and life quality. Numerous strategies have been developed for the treatment of wounds, including skin substitutes, biomembranes, scaffolds, and smart dressings. The excellent properties of fibroin can be exploited for the development of advanced wound dressing biomaterials, aiming at promoting the wound healing process. In this work, silk fibroin films modified through the addition of glucose were developed to enhance flexibility of medical device without affecting the biocompatibility, to promote wound healing and to improve the patient well-being. The glucose/fibroin blend was characterized through Fourier transform infrared spectroscopy and differential scanning calorimetry to analyze the protein structure. Absorption capacity, mechanical properties, wettability and bacterial biofilm formation on silk fibroin films were also analyzed to study the effect of the addition of a plasticizer on the properties of the wound dressing. The stability of the films was analyzed through in vitro biodegradability tests. The biocompatibility and regenerative properties were demonstrated through appropriate cellular assays. The results demonstrated that the addition of glucose induced crystallization and provided good flexibility and absorption capacity of silk fibroin films. Glucose modified silk fibroin films were biocompatible and had a positive effect in promoting the wound closure. (c) 2018 Wiley Periodicals, Inc. J Biomed Mater Res Part B: Appl Biomater, 2018. PMID- 29451716 TI - Improving Growth for Infants <=1250 Grams Receiving an Exclusive Human Milk Diet. AB - BACKGROUND: An exclusive human milk diet (EHM) fortified with human milk-based fortifier decreases necrotizing enterocolitis (NEC) compared to maternal milk supplemented with preterm formula and bovine fortifier (PTF). Growth has been less with EHM and also maternal milk supplemented with donor human milk and bovine fortifier (HMBF). The objective was to evaluate the effect of a standardized feeding protocol on the growth of infants <=1250 g birth weight supported with EHM and HMBF. The effect on the incidence of NEC was also evaluated. DESIGN/METHODS: A retrospective study of growth before and after implementation of a feeding protocol for infants who received either EHM or HMBF. Primary outcomes were weight, length, and head circumference gain velocities from birth to discharge. The incidence of NEC was also recorded. RESULTS: Analysis of covariance for 379 total infants showed that earlier day of life for fortification to 24 Kcal/oz was associated with increased weight gain (p = 0.0166) and length gain (p = 0.0064). Implementation of the feeding protocol was associated with increased head circumference gain (p = 0.006). EHM was associated with decreased incidence of NEC (p = 0.0302). CONCLUSIONS: Implementation of a standardized feeding protocol including earlier fortification of maternal milk was associated with improved growth for infants receiving human milk feedings. EHM significantly decreased NEC. Earlier fortification had no effect on NEC. PMID- 29451715 TI - Transitions in sex determination and sex chromosomes across vertebrate species. AB - Despite the prevalence of sexual reproduction across eukaryotes, there is a remarkable diversity of sex-determination mechanisms. The underlying causes of this diversity remain unclear, and it is unknown whether there are convergent trends in the directionality of turnover in sex-determination mechanisms. We used the recently assembled Tree of Sex database to assess patterns in the evolution of sex-determination systems in the remarkably diverse vertebrate clades of teleost fish, squamate reptiles and amphibians. Contrary to theoretical predictions, we find no evidence that the evolution of separate sexes is irreversible, as transitions from separate sexes to hermaphroditism occur at higher rates than the reverse in fish. We also find that transitions from environmental sex determination to genetic sex determination occur at higher rates than the reverse in both squamates and fish, suggesting that genetic sex determination is more stable. However, our data are not consistent with the hypothesis that heteromorphic sex chromosomes are an "evolutionary trap." Rather, we find similar transition rates between homomorphic and heteromorphic sex chromosomes in both fish and amphibians, and to environmental sex determination from heteromorphic vs. homomorphic sex chromosome systems in fish. Finally, we find that transitions between male and female heterogamety occur at similar rates in amphibians and squamates, while transitions to male heterogamety occur at higher rates in fish. Together, these results provide the most comprehensive view to date of the evolution of vertebrate sex determination in a phylogenetic context, providing new insight into long-standing questions about the evolution of sexual reproduction. PMID- 29451717 TI - Modeling of cytometry data in logarithmic space: When is a bimodal distribution not bimodal? AB - Recent efforts in systems immunology lead researchers to build quantitative models of cell activation and differentiation. One goal is to account for the distributions of proteins from single-cell measurements by flow cytometry or mass cytometry as readout of biological regulation. In that context, large cell-to cell variability is often observed in biological quantities. We show here that these readouts, viewed in logarithmic scale may result in two easily distinguishable modes, while the underlying distribution (in linear scale) is unimodal. We introduce a simple mathematical test to highlight this mismatch. We then dissect the flow of influence of cell-to-cell variability proposing a graphical model which motivates higher-dimensional analysis of the data. Finally we show how acquiring additional biological information can be used to reduce uncertainty introduced by cell-to-cell variability, helping to clarify whether the data is uni- or bimodal. This communication has cautionary implications for manual and automatic gating strategies, as well as clustering and modeling of single-cell measurements.

AB - Sebocytes, the major cell type in sebaceous glands, are differentiated epithelial cells that gradually accumulate lipids and eventually disrupt, releasing their content (sebum) in a secretory process known as holocrine secretion. Via the hair canal, sebum reaches the skin surface, where it has several known or postulated functions, including pheromonal, thermoregulatory, antimicrobial and antioxidant activities. Altered sebum secretion and/or structural sebaceous gland changes have also been involved in the pathogenesis of skin diseases, such as acne vulgaris and some forms of alopecia. Here, we assess how recent work employing primary sebocytes and sebaceous gland cell lines contributed for our understanding of sebaceous lipogenesis and its role in skin health and disease. PMID- 29451718 TI - KIAA0247 inhibits growth, migration, invasion of non-small-cell lung cancer through regulating the Notch pathway. AB - Lung cancer remains the leading cause of cancer-related death worldwide. Previous studies have shown that the novel KIAA0247 gene potentially targeted by the tumor suppressor p53 may inhibit the development of several cancers. However, the exact function of KIAA0247 in non-small-cell lung cancer (NSCLC) is unknown. The purpose of the present study was to clarify the role of KIAA0247 in NSCLC. KIAA0247 expression was evaluated in tumors and adjacent normal tissues of 197 NSCLC patients by immunohistochemistry and real-time PCR and analyzed for association with clinicopathological parameters. Results indicated that KIAA0247 levels positively correlated with cell differentiation (P < .001) and patient survival (P < .0001) and negatively correlated with lymph node metastasis (P < .001) and advanced p-TNM stage (P < .001). In cultured NSCLC cell lines, KIAA0247 overexpression inhibited cell migration, invasion, and proliferation and downregulated the expression of Jagged1, Notch1 intracellular domain (NICD), Snail, cyclin D1, RhoA, RhoC, and MMP9, while upregulating that of E-cadherin and p21. The Notch inhibitor DAPT reduced the biological effects of KIAA0247 knockdown, suggesting that KIAA0247 decreased the carcinogenic activity of NSCLC cells through downregulation of Notch signaling. Our results indicate that KIAA0247 inhibits NSCLC progression by reducing the metastatic potential of cancer cells through downregulation of the Notch pathway, which may underlie the association of KIAA0247 expression with favorable clinicopathological characteristics of NSCLC patients. These findings suggest that KIAA0247 is a candidate prognostic biomarker and potential therapeutic target in NSCLC. PMID- 29451720 TI - Detection of membrane protein-protein interaction in planta based on dual-intein coupled tripartite split-GFP association. AB - Despite the great interest in identifying protein-protein interactions (PPIs) in biological systems, only a few attempts have been made at large-scale PPI screening in planta. Unlike biochemical assays, bimolecular fluorescence complementation allows visualization of transient and weak PPIs in vivo at subcellular resolution. However, when the non-fluorescent fragments are highly expressed, spontaneous and irreversible self-assembly of the split halves can easily generate false positives. The recently developed tripartite split-GFP system was shown to be a reliable PPI reporter in mammalian and yeast cells. In this study, we adapted this methodology, in combination with the beta-estradiol inducible expression cassette, for the detection of membrane PPIs in planta. Using a transient expression assay by agroinfiltration of Nicotiana benthamiana leaves, we demonstrate the utility of the tripartite split-GFP association in plant cells and affirm that the tripartite split-GFP system yields no spurious background signal even with abundant fusion proteins readily accessible to the compartments of interaction. By validating a few of the Arabidopsis PPIs, including the membrane PPIs implicated in phosphate homeostasis, we proved the fidelity of this assay for detection of PPIs in various cellular compartments in planta. Moreover, the technique combining the tripartite split-GFP association and dual-intein-mediated cleavage of polyprotein precursor is feasible in stably transformed Arabidopsis plants. Our results provide a proof-of-concept implementation of the tripartite split-GFP system as a potential tool for membrane PPI screens in planta.

AB - New treatments for type 1 diabetes are an unmet need. We investigated the efficacy and safety of adding sodium-glucose co-transporter-2 (SGLT2) inhibitors to insulin for type 1 diabetes by conducting a meta-analysis of prospective randomized, placebo-controlled trials. A search of electronic databases up to October 2017 identified 1361 studies, of which 14 were investigated (N = 4591). Meta-analysis showed that SGLT2 inhibitor therapy significantly reduced glycated haemoglobin (HbA1c) concentration by 0.4% (95% confidence interval [CI] 0.35, 0.46; P < .001, I2 = 0%), fasting plasma glucose by 1.14 mmol/L (95% CI 0.8,1.47), body weight by 2.68 kg (95% CI 2.0, 3.36), and systolic blood pressure by 3.37 mmHg (95% CI 1.46, 5.28). In addition, bolus insulin decreased by 3.6 units/day (95% CI 2.0, 5.3), and basal insulin decreased by 4.2 units/day (95% CI 2.2, 6.3). Continuous glucose monitoring showed a decrease in glucose excursions compared with placebo, with reduced variation of mean blood glucose, glucose standard deviation, and mean amplitude of glucose excursion. There was no significant increase in the rate of hypoglycaemia or severe hypoglycaemia; however, SGLT2 inhibitor therapy increased diabetic ketoacidosis (odds ratio [OR] 3.38) and genital tract infection (OR 3.44). Add-on SGLT2 inhibitor therapy might be advantageous for type 1 diabetes, but its use should be considered carefully. PMID- 29451722 TI - Enhanced Photodynamic Therapy by Reduced Levels of Intracellular Glutathione Obtained By Employing a Nano-MOF with CuII as the Active Center. AB - In photodynamic therapy (PDT), the level of reactive oxygen species (ROS) produced in the cell directly determines the therapeutic effect. Improvement in ROS concentration can be realized by reducing the glutathione (GSH) level or increasing the amount of photosensitizer. However, excessive amounts photosensitizer may cause side effects. Therefore, the development of photosensitizers that reduce GSH levels through synergistically improving ROS concentration in order to strengthen the efficacy of PDT for tumor is important. We report a nano-metal-organic framework (CuII -metalated nano-MOF {CuL-[AlOH]2 }n (MOF-2, H6 L=mesotetrakis(4-carboxylphenyl)porphyrin)) based on CuII as the active center for PDT. This MOF-2 is readily taken up by breast cancer cells, and high levels of ROS are generated under light irradiation. Meanwhile, intracellular GSH is considerably decreased owing to absorption on MOF-2; this synergistically increases ROS concentration and accelerates apoptosis, thereby enhancing the effect of PDT. Notably, based on the direct adsorption of GSH, MOF 2 showed a comparable effect with the commercial antitumor drug camptothecin in a mouse breast cancer model. This work provides strong evidence for MOF-2 as a promising new PDT candidate and anticancer drug. PMID- 29451723 TI - Clickable Polyamine Derivatives as Chemical Probes for the Polyamine Transport System. AB - Polyamines are essential for cell growth and differentiation, but their trafficking by the polyamine transport system is not fully understood. Herein, the synthesis of several azido-derivatized polyamines for easy conjugation by click chemistry is described. Attachment of a 4,4-difluoro-4-bora-3a,4a-diaza-s indacene (BODIPY) dye gave fluorescent polyamine probes, which were tested in cell culture. The linear probe series showed superior cellular uptake compared with that of probes in which the dye was attached to a branch on one of the central amines. Interestingly, the linear probes accumulated rapidly in cancer cells (MCF-7), but not in nontumorigenic cells (MCF-10A). The fluorescent polyamine probes are therefore applicable to the study of polyamine trafficking, whereas the azido polyamines may be further utilized to transport cargo into cancer cells by exploiting the polyamine transport system.

AB - The palladium-catalyzed coupling reaction of N-hydroxyphthalimide esters and styrenes to deliver exclusively (E)-substituted olefins under irradiation with visible light is reported. This method tolerates N-hydroxyphthalimide esters derived from primary, secondary, tertiary as well as benzylic carboxylic acids. Notably, Pd(PPh3 )4 is employed as an inexpensive palladium source and no addition of base or classical photocatalyst is required. Mechanistic studies suggest a light-mediated single-electron reduction of the activated acid by a photoexcited palladium(0) species to access alkyl radicals through decarboxylation. PMID- 29451726 TI - Single organelle dynamics linked to 3D structure by correlative live-cell imaging and 3D electron microscopy. AB - Live-cell correlative light-electron microscopy (live-cell-CLEM) integrates live movies with the corresponding electron microscopy (EM) image, but a major challenge is to relate the dynamic characteristics of single organelles to their 3-dimensional (3D) ultrastructure. Here, we introduce focused ion beam scanning electron microscopy (FIB-SEM) in a modular live-cell-CLEM pipeline for a single organelle CLEM. We transfected cells with lysosomal-associated membrane protein 1 green fluorescent protein (LAMP-1-GFP), analyzed the dynamics of individual GFP positive spots, and correlated these to their corresponding fine-architecture and immediate cellular environment. By FIB-SEM we quantitatively assessed morphological characteristics, like number of intraluminal vesicles and contact sites with endoplasmic reticulum and mitochondria. Hence, we present a novel way to integrate multiple parameters of subcellular dynamics and architecture onto a single organelle, which is relevant to address biological questions related to membrane trafficking, organelle biogenesis and positioning. Furthermore, by using CLEM to select regions of interest, our method allows for targeted FIB-SEM, which significantly reduces time required for image acquisition and data processing.

AB - A mild and selective C(sp3 )-H aerobic oxidation enabled by decatungstate photocatalysis has been developed. The reaction can be significantly improved in a microflow reactor enabling the safe use of oxygen and enhanced irradiation of the reaction mixture. Our method allows for the oxidation of both activated and unactivated C-H bonds (30 examples). The ability to selectively oxidize natural scaffolds, such as (-)-ambroxide, pregnenolone acetate, (+)-sclareolide, and artemisinin, exemplifies the utility of this new method.

AB - The monomolecular cracking rates of propane and n-butane over MFI, CHA, FER and TON zeolites were determined simultaneously with the coverage of active sites at reaction condition using IR operando spectroscopy. This allowed direct determination of adsorption thermodynamics and intrinsic rate parameters. The results show that the zeolite confinement mediates enthalpy-entropy trade-offs only at the adsorbed state, leaving the true activation energy insensitive to the zeolite or alkane structure while the activation entropy was found to increase with the confinement. Hence, relative cracking rates of alkanes within zeolite pores are mostly governed by activation entropy.

AB - Metal-organic frameworks (MOFs) are a chemically and topologically diverse family of materials composed of inorganic nodes and organic linkers bound together by coordination bonds. Presented here are two significant innovations in this field. The first is the use of a new coordination group, phenylene-1,4 bis(methylphosphinic acid) (PBPA), a phosphinic acid analogue of the commonly used terephtalic acid. Use of this new linker group leads to the formation of a hydrothermally stable and permanently porous MOF structure. The second innovation is the application of electron-diffraction tomography, coupled with dynamic refinement of the EDT data, to the elucidation of the structure of the new material, including the localization of hydrogen atoms.

PMID- 29451738 TI - Well differentiated grade 3 pancreatic neuroendocrine tumors compared with related neoplasms: A morphologic study. AB - BACKGROUND: Pancreatic neuroendocrine neoplasms with a Ki-67 labeling index greater than 20% were reclassified in 2017 by the World Health Organization into well differentiated (WD) and poorly differentiated grade 3 neuroendocrine carcinoma (NEC). The authors describe the cytologic features of grade 3 WD pancreatic neuroendocrine neoplasms compared with grade 2 neoplasms and NEC. METHODS: Fine-needle aspirates from 65 pancreatic neuroendocrine neoplasms were reviewed, and their cytomorphologic features were compared across grade 2, WD grade 3, and PD small cell type (PD-S), large cell type (PD-L), and type not otherwise specified (PD-NOS) neoplasms. RESULTS: The 65 aspirates consisted of 19 grade 2 neoplasms, 32 WD grade 3 neoplasms, and 14 NECs (6 PD-S, 5 PD-L, and 3 PD NOS). The medians Ki-67 proliferation index was 11% (range, 3.2%-17%) in grade 2 neoplasms, 40% (range, 21%-89%) in WD grade 3 neoplasms, 80% (range, 63%-95%) in PD-S neoplasms, 39% (range, 25%-61%) in PD-L neoplasms, and 70% (range, 30%-80%) in PD-NOS neoplasms. Both grade 2 and WD grade 3 neoplasms were associated with plasmacytoid morphology and smooth nuclear contours, but WD grade 3 neoplasms had significant increases in abundant cytoplasm (72% vs 17%; P = .007), nuclear tangles (75% vs 42%; P = .006), and apoptosis (86% vs 58%; P = .005). Compared with NECs, WD grade 3 neoplasms had increased plasmacytoid morphology (75% vs 7%; P < .001), smooth nuclear contours (94% vs 64%; P = .02), round nuclei (59% vs 21%; P = .01), and less pleomorphism (13% vs 50%; P = .004), molding (9% vs 79%; P < .001), and necrosis (13% vs 43%; P = .003). WD grade 3 neoplasms had less pleomorphism (13% vs 50%; P = .04), less necrosis (13% vs 60%; P = .04), and more plasmacytoid morphology (75% vs 20%; P = .03) than PD-L. CONCLUSIONS: The prevalence of cytologic features differs in WD grade 3 pancreatic neuroendocrine neoplasms compared with grade 2 neoplasms and NECs, and these differences assist in the recognition of this newly classified entity.

AB - Stacking interactions can be important enthalpic contributors to drug binding. Among the less well-studied stacking interactions are those occurring between an arene and the pi-face of an amide group. Given the ubiquity of heterocycles in drugs, combined with the abundance of amides in the protein backbone, optimizing these noncovalent interactions can provide a potential route to enhanced drug binding. Previously, Diederich et al. (ChemMedChem 2013, 8, 397-404) studied stacked dimers of a model amide with a set of 18 heterocycles, showing that computed interaction energies correlate with the dipole moments of the heterocycles and providing guidelines for the optimization of these interactions. We considered stacked dimers of the same model amide with a larger set of 28 heterocycles common in pharmaceuticals, by using more robust ab initio methods. While the overall trends in these new data corroborate many of the results of Diederich et al., these data provide a more refined view of the nature of amide stacking interactions. We present a robust scoring function for amide stacking interaction energies based on the molecular dipole moment and strength of the electric field above the arene. PMID- 29451740 TI - Caveat Usor: Assessing Differences between Major Chemistry Databases. AB - The three databases of PubChem, ChemSpider, and UniChem capture the majority of open chemical structure records with February 2018 totals of 95, 63, and 154 million, respectively. Collectively, they constitute a massively enabling resource for cheminformatics, chemical biology, and drug discovery. As meta portals, they subsume and link out to the major proportion of public bioactivity data extracted from the literature and screening center assay results. Therefore, they not only present three different entry points, but the many subsumed independent resources present a fourth entry point in the form of standalone databases. Because this creates a complex picture it is important for users to have at least some appreciation of differential content to enable utility judgments for the tasks at hand. This turns out to be challenging. By comparing the three resources in detail, this review assesses their differences, some of which are not obvious. This includes the fact that coverage is significantly different between the 587, 282, and 38 contributing sources, respectively. This not only presents the "who-has-what" question, but also the reason "why" any particular inclusion is considered valuable is rarely made explicit. Also confusing is that sources nominally in common (i.e., having the same submitter name) can have significantly different structure counts, not only in each of the three but also from their standalone instantiations. Assessing a series of examples indicates that differences in loading dates and structural standardization are the main causes of this inter-portal discordance. PMID- 29451741 TI - Non-invasive optical method for real-time assessment of intracorneal riboflavin concentration and efficacy of corneal cross-linking. AB - Keratoconus is the primary cause of corneal transplantation in young adults worldwide. Riboflavin/UV-A corneal cross-linking may effectively halt the progression of keratoconus if an adequate amount of riboflavin enriches the corneal stroma and is photo-oxidated by UV-A light for generating additional cross-linking bonds between stromal proteins and strengthening the biomechanics of the weakened cornea. Here we reported an UV-A theranostic prototype device for performing corneal cross-linking with the ability to assess corneal intrastromal concentration of riboflavin and to estimate treatment efficacy in real time. Seventeen human donor corneas were treated according to the conventional riboflavin/UV-A corneal cross-linking protocol. Ten of these tissues were probed with atomic force microscopy in order to correlate the intrastromal riboflavin concentration recorded during treatment with the increase in elastic modulus of the anterior corneal stroma. The intrastromal riboflavin concentration and its consumption during UV-A irradiation of the cornea were highly significantly correlated (R = 0.79; P = .03) with the treatment-induced stromal stiffening effect. The present study showed an ophthalmic device that provided an innovative, non-invasive, real-time monitoring solution for estimating corneal cross-linking treatment efficacy on a personalized basis. PMID- 29451742 TI - Real-time monitoring prefrontal activities during online video game playing by functional near-infrared spectroscopy. AB - A growing body of literature has suggested that video game playing can induce functional and structural plasticity of the brain. The underlying mechanisms, however, remain poorly understood. In this study, functional near-infrared spectroscopy (fNIRS) was used to record prefrontal activities in 24 experienced game players when they played a massively multiplayer online battle arena video game, League of Legends (LOL), under naturalistic conditions. It was observed that game onset was associated with significant activations in the ventrolateral prefrontal cortex (VLPFC) and concomitant deactivations in the dorsolateral prefrontal cortex (DLPFC) and frontal pole area (FPA). Game events, such as slaying an enemy and being slain by an enemy evoked region-specific time-locked hemodynamic/oxygenation responses in the prefrontal cortex (PFC). It was proposed that the VLPFC activities during LOL playing are likely responses to visuo-motor task load of the game, while the DLPFC/FPA activities may be involved in the constant shifts of attentional states and allocation of cognitive resources required by game playing. The present study demonstrated that it is feasible to use fNIRS to monitor real-time prefrontal activity during online video game playing. PMID- 29451743 TI - Serum adiponectin and insulin secretion: A direct or inverse association? AB - We investigated the association between serum high molecular weight (HMW) adiponectin and insulin secretion in a population-based study, with or without adjustment for insulin sensitivity. A total of 488 participants (263 women) were included in the present study. Insulin secretion was estimated using the homeostasis model assessment of beta-cell function +/- adjustment for insulin resistance using the disposition index. Multivariate analysis showed that HMW adiponectin was significantly and inversely associated with homeostasis model assessment of beta-cell function (partial regression coefficient -0.19, 95% confidence interval -0.28, -0.10, P < 0.0001). However, HMW adiponectin was significantly and positively associated with disposition index (partial regression coefficient 0.15, 95% confidence interval 0.06, 0.24, P = 0.0016). The present study showed that a positive association between HMW adiponectin levels and insulin secretion evaluated using an index incorporating adjustment for insulin resistance was identified, and vice versa using an index that did not adjust for insulin resistance. PMID- 29451744 TI - Design, Synthesis, and Biological Evaluation of Bivalent Ligands Targeting Dopamine D2 -Like Receptors and the MU-Opioid Receptor. AB - Currently, there is mounting evidence that intermolecular receptor-receptor interactions may result in altered receptor recognition, pharmacology and signaling. Heterobivalent ligands have been proven useful as molecular probes for confirming and targeting heteromeric receptors. This report describes the design and synthesis of novel heterobivalent ligands for dopamine D2 -like receptors (D2 -likeR) and the MU-opioid receptor (MUOR) and their evaluation using ligand binding and functional assays. Interestingly, we identified a potent bivalent ligand that contains a short 18-atom linker and combines good potency with high efficacy both in beta-arrestin 2 recruitment for MUOR and MAPK-P for D4 R. Furthermore, this compound was characterized by a biphasic competition binding curve for the D4 R-MUOR heterodimer, indicative of a bivalent binding mode. As this compound possibly bridges the D4 R-MUOR heterodimer, it could be used as a pharmacological tool to further investigate the interactions of D4 R and MUOR. PMID- 29451745 TI - Detection of ROS1-positive non-small cell lung cancer on cytological specimens using immunocytochemistry. AB - BACKGROUND: Rearrangements of the ROS1 oncogene are found in 1% to 2% of non small cell lung cancers (NSCLC) and are regarded as mutually exclusive oncogenic driver mutations. Since the approval of targeted therapy for ROS1-positive NSCLC, ROS1 testing has become a part of the diagnostic routine. Fluorescence in situ hybridization (FISH), optionally selected for by immunohistochemistry on histological material, is a common practice for the detection of ROS1 rearrangements. However, NSCLC often is diagnosed by cytology alone, requiring predictive marker testing on cytological specimens. In the current study, the authors explored the accuracy of ROS1 immunocytochemistry (ICC) on non-cell block cytological specimens for the detection of ROS1 rearrangements. METHODS: ICC using the D4D6 antibody on an automated immunostainer was performed prospectively in the routine diagnostic setting on cytological specimens from 295 patients with NSCLC, including adenocarcinoma (241 patients), NSCLC not otherwise specified (50 patients), and other malignancies (4 patients). Any immunostaining was considered positive. RESULTS: ICC was positive in all 13 ROS1-rearranged NSCLC cases confirmed by FISH (12 cases) or next-generation sequencing (1 case). Confirmation of 282 ICC-negative cases was available for 208 patients. The sensitivity, specificity, and positive and negative predictive values for ROS1 ICC compared with the final ROS1 status all were 100%. CONCLUSIONS: ROS1 ICC is an accurate method for the detection of ROS1 rearrangements in NSCLC. Given the high costs and technical challenges of FISH and the rarity of ROS1 rearrangements, ICC is rapid and therefore well suited as a screening method. Cases with equivocal or positive findings on ICC can be confirmed by FISH or molecular tests. Cancer Cytopathol 2018;126:421-9. (c) 2018 American Cancer Society.

AB - In India the distribution of genus Triplophysa has been reported only in the upper drainage of theIndus River in Jammu and Kashmir and Lahul and Spiti area of Himachal Pradesh. There is no study on thetaxonomic characterization of this genus from Kashmir Himalaya. Therefore the present study was aimed tocharacterize two important fish species Triplophysa marmorata and T. kashmirensis from Kashmir valley, byusing morphometric and molecular tools. It is difficult to discriminate these two species due to the poor qualityof original descriptions, and the lack of good reviews. Keeping this in view, a morphometric and molecularstudy was conducted. Morphometric data were analyzed by using univariate analysis of variance (ANOVA) andmultivariate analyses (Principal component analysis) and mtDNA marker Cytochrome oxidase 1 was used formolecular support. Altogether, 22 morphometric characters were used and 15 characters were found significantlyvariable (P < 0.05). First two components of principal component analysis (PCA) i.e. PC1 and PC2 groupedthese two species into separate clusters. The Cytochrome oxidase 1 analysis showed that the mean intraspecificnucleotide divergence (K2P) was 0.001 and interspecific nucleotide divergence was 0.007. Despite havinglow K2P divergence, these two species got separated into two distinct clades in both Neighbour joining (NJ)and Unweighted Pair Group Method with Arithmetic Mean (UPGMA) tree building methods. But the patternof clade formation showed that these species were recently radiated from each other and may have the sameancestor. Furthermore, these two species were found closer to Nemacheilidae than to Balitoridae family inthe phylogenetic analysis. The molecular divergence between these species was also supported by variance inmorphometric data. This work may build the base for the revision of taxonomic identity of these two importantfishes of genus Triplophysa. The present investigation formulated that, based on morphological and mtDNA COIsequences analysis, these two taxonomic Triplophysa species should be considered as valid. The results may furtherassist to enhance the knowledge of the ichthyologists in understanding the ichthyofauna of Kashmir Valleyand will help them in planning strategies for conservation and management of these less studied small indigenousspecies along their natural range of distribution. PMID- 29451749 TI - Seed colour affects light and temperature requirements during germination in two Lotus species (Fabaceae) of the Arabian subtropical deserts. AB - Heterogeneity in seeds mostly occurs due to physiological, environmental and genetic factors, andthese could affect seed dormancy and germination. Therefore, the aim of our study was to assess the effect ofseed colour on germination behavior. For this, both light and temperature requirements were assessed in Lotusglinoides and Lotus halophilus (Fabaceae) from the hyper-arid deserts of the United Arab Emirates. Germinationwas assessed in terms of both final germination level (percentage) and germination rate, as expressed byTimson's germination velocity index. Lotus glinoides produces black and yellow-colored seeds, and L. halophilusproduces green and yellow seeds. Different seed lots were germinated in both light and darkness at differenttemperatures. Yellow seeds of the two species attained significantly lower germination, compared to black andgreen seeds. There was no specific light or temperature requirements for the germination of the two colouredseeds of L. glinoides; the effect of interactions between seed colour and both light and incubation temperature,were not significant on the final germination percentage. In L. halophilus, green seeds germinated significantlymore in both light and darkness at lower temperatures (15/25 degrees C) and in light at higher temperatures (25/35 degrees C), compared to yellow seeds. Yellow seeds germinated faster, compared to black at 15/25 degrees C in L. glinoidesand compared to green seeds at 15/25 degrees C and 25/35 degrees C in L. halophilus. Seed colour variation, at least in L.halophilus, could be a survival strategy that would determine the time of germination throughout the year in theunpredictable desert environment. PMID- 29451750 TI - Comparison of forest regeneration in two sites with different primate abundances in Northwestern Ecuador. AB - There is increasing evidence that large-bodied primates play important roles as seed dispersers andin the maintenance of tree diversity in forest ecosystems. In this study we compared forest regeneration at twosites with differing primate abundances in the Ecuadorian Chocoan rainforest. We predicted: (1) significant differencesin primate abundance between the two sites; (2) higher understory tree species richness and density atthe site with greater primate abundance; (3) the site with lower primate abundance characterized by tree speciesdispersed by non primate biotic agents and/or abiotic factors. We compared two sites, Tesoro Escondido (TE)a campesino cooperative, and the El Pambilar (EP) wildlife refuge that both maintain populations of mantledhowler monkey (Alouatta palliata), the brown-headed spider monkey (Ateles fusciceps fusciceps) and the capuchinmonkey (Cebus capucinus). We characterized canopy structure by point-quadrant sampling, determinedprimate abundance and sampled seedlings/saplings in 1 m2 plots, classifying tree species based on three dispersalsyndromes: adapted for primate dispersal, dispersed by other biological agents, and abiotic dispersal. We comparedsites in terms of primate abundance (groups and individuals observed per day) and regeneration characteristics(overall density, species richness, and dispersal syndrome). We carried out within site comparisons andconstructed understory tree species accumulation curves. Overall the forests were structurally similar - with significantlyhigher densities of A. f. fusciceps at TE. Encounter rates for the other two primate species were similarat both sites. Understory tree density and species richness was significantly higher in TE with no stabilization oftree species accumulation curves. The species accumulation curve for understory trees at EP stabilized. Higherdensities and species richness of primate dispersed tree species were observed at TE, with non-primate bioticallydispersed tree species the dominant dispersal syndrome at both sites. Our observations are consistent with thosefrom other studies investigating the role of large-bodied frugivorous primates in forest regeneration, and pointto a general pattern: future lowland tropical forest tree diversity depends on maintaining robust populations oflarge primate species in these systems. It is highly probable that the maintenance of high levels of tree diversityin Chocoan rainforests is dependent on the conservation of its largest resident primate, the critically endangeredbrown-headed spider monkey (A. f. fusciceps). PMID- 29451751 TI - Resource allocation in Copaifera langsdorffii (Fabaceae): how supra-annual fruiting affects plant traits and herbivory? AB - Plants have limited resources to invest in reproduction, vegetative growth and defense against herbivorous.Trade-off in resources allocation promotes changes in plant traits that may affect higher trophic levels.In this study, we evaluated the trade-off effect between years of high and low fruiting on the investment ofresources for growth and defense, and their indirect effects on herbivory in Copaifera langsdorffii. Our questionswere: (i) does the resource investment on reproduction causes a depletion in vegetative growth as predicted bythe Carbon/Nutrient Balance hypothesis (CNBH), resulting in more availability of resources to be allocated fordefense?, (ii) does the variation in resource allocation for growth and defense between years of high and lowfruiting leads to indirect changes in herbivory? Thirty-five trees located in a Cerrado area were monitored during2008 (year of high fruiting) and 2009 (year of no fruiting) to evaluate the differential investment in vegetativetraits (biomass, growth and number of ramifications), plant defense (tannin concentration and plant hypersensitivity)and herbivory (galling attack and folivory). According to our first question, we observed that in thefruiting year, woody biomass negatively affected tannin concentration, indicating that fruit production restrictedthe resources that could be invested both in growth as in defense. In the same way, we observed an inter-annualvariation in herbivorous attack, and found that plants with higher leaf biomass and tannin concentration, experiencedhigher galling attack and hypersensitive reaction, regardless years. These findings suggested that plants'resistance to herbivory is a good proxy of plant defense and an effective defense strategy for C. langsdorffii,besides the evidence of indirect responses of the third trophic level, as postulated by the second question. Insummary, the supra-annual fruiting pattern promoted several changes on plant development, demonstrating theimportance of evaluating different plant traits when characterizing the vegetative investment. As expected bytheory, the trade off in resource allocation favored changes in defense compounds production and patterns ofherbivory. The understanding of this important element of insect-plant interactions will be fundamental to deciphercoevolutionary life histories and interactions between plant species reproduction and herbivory. Besidesthat, only through long-term studies we will be able to build models and develop more accurate forecasts aboutthe factors that trigger the bottom-up effect on herbivory performance, as well the top-down effect of herbivoreson plant trait evolution.

AB - The golden mussel Limnoperna fortunei is an invasive species that has quickly dispersed and colonized several potential different habitats distributed all over the world, causing environmental and economic impacts. Thus, in order to contribute to a better understanding of the reproductive aspects of L. fortunei, we described the cellular dynamic of the male and female germinal epithelium during the annual reproductive life history of this species, with the use of high resolution histology. An approximate of 1 200 specimens of L. fortunei were sampled periodically on the upper Parana River floodplain (Brazil), from March 2010 to December 2012. Based on the activity of the germinal epithelium and consequent germ cell development, this study has resulted in the recognition of the following reproductive phases: Developing, Spawning Capable, Regressing and Regenerating. In the characterization of these phases, the following germ cells were described for males: spermatogonia, primary and secondary spermatocytes, spermatids and spermatozoa. Cell nests, oogonia, early prophase oocytes, previtellogenic oocytes and vitellogenic oocytes (early vitellogenic oocytes, middle vitellogenic oocytes and full-grown oocytes) were described for females. The morphological data and reproductive parameters obtained, showed the value of the cellular dynamics of the germinal epithelium, for the understanding of the cyclic gonadal events during the adult reproductive life of the mollusk in general. These results on the gametogenesis of this invasive species may be a fundamental tool for the development of control strategies and programs implementation, to reduce their proliferation and impacts in natural local environments.

AB - Early development of fish larvae is a highly dynamic process and its study may provide importantinformation about ontogenetic development, bioenergetic growth, behaviour, taxonomic characteristics for identificationin natural environments, identification of spawning areas, and population monitoring. With the aim toprovide knowledge about their growth and behaviour, to support larval rearing, and also taxonomic purposes, westudied the life history of the Prochilodus argenteus and P. costatus from hatching until the complete absorptionof the yolk. Larvae were obtained through artificial reproduction at the Hydrobiology and Aquaculture Stationof Tres Marias, Minas Gerais, Brazil. Immediately after hatching, 100 larvae of each species were put in twoplastic incubators for conditioning. On a daily basis, larvae behavior was recorded and 14 larvae of each specieswere collected to analyse body morphology. On the first day after hatching, larvae of P. costatus and P. argenteusshowed an elongated and transparent body; the yolk sac was filled with individualized yolk globules. In bothspecies, the embryonic fin rounded the caudal region of the body, the retina was non-pigmented and the gut wasobliterated. At the second day post-hatching, larvae of both species dendritic chromatophores had emerged, themouth was obliterated and the pectoral fin was observed. The larvae showed 38-43 myomeres in P. costatus and42-43 in P. argenteus. For both species, the gas bladder was inflated and the lumen of the gut was already open.On the third day post hatching, the mouth of P. costatus and P. argenteus was already open in a sub terminalposition; the retina was pigmented; the gill arches had lamellar protrusions and were partially covered by theoperculum. On the fourth day post hatching, the pigmentation pattern was maintained with greater intensity; themouth occupied a terminal position, the yolk sac was almost completely reabsorbed, and the pectoral and caudalfins showed mesenchymal rays in both species. The gut showed a broad lumen with folded mucosa and epitheliumwith striated border. The larvae of both species showed similar swimming behaviour. Our study providedunderstanding about the morphophysiological aspects, species identification, larval development and growth,and the ontogenic characteristics of two Neotropical fishes with importance for commercial and sports fishing.

Eventhough severalspecies have been described for this genus, information about this group is still scarce. This study investigatedsome biological aspects and mating behavior in Leucothyreus albopilosus. Studies were conducted at the StateUniversity of Mato Grosso do Sul, in the municipalities of Aquidauana and Cassilandia, MS, Brazil. For biologicalstudies, adults were collected with light traps from February 2011 to February 2012, and for behavioranalyses from September to December 2014. Biological studies were undertaken every three days and includedthe eggs inspection, and the separation of the newly hatched larvae to observe and describe their developmentalstages; to monitor larval growth and differentiate larval instars, we measured the larvae cephalic capsule. Lifecycle was determined starting from the newly laid eggs until adult death. For mating behavior studies, adultsobtained with light traps were taken to the laboratory. As soon as they started flying in the evening, couples wereformed and copulation steps were recorded. In the field, we observed that adults were mostly collected duringwarmer and wetter periods (from August to March). Our results showed that the embryonic period of L. albopilosuslasted 20.5 days, the 1st, 2nd and 3rd instars lasted 31.0, 33.1 and 85.6 days, respectively. The pupal stagelasted 20 days, and the egg to adult period was completed in 185.5 days; these results suggest that L. albopilosuscan be characterized as a univoltine species. Observations of mating behavior in the laboratory showed that, afterthe sunset, adults projected a small portion of clypeus near the soil surface and flew off seeking a female to mate.The female could accept or reject the male for mating. When the female accepted the male, copulation occurredfrom 19:00 to 23:00 hours, and lasted 19.45 minutes on average. Sometimes females refused to mate, probablybecause the male or female were not sexually mature to perform copulation, and there might be a chemicalcommunication between the adults. Adults were observed feeding on ripe bananas (Musa sp., Musaceae) and onmangaba flowers (Hancornia speciosa, Apocynaceae) in the laboratory. With this work we contributed with thedescription of mating behavior in the genus Leucothyreus and concluded that the biological cycle was completedin less than 200 days.

AB - The largemouth bass Micropterus salmoides is a very valuable fish species for aquaculture and sport fishing; however, there are nosystematic studies on fish metazoan parasites in Mexico. The main objective of the present study was to describethe prevalence, abundance, and intensity of M. salmoides metazoan parasites, and their association with fishcondition factor and gender. The sample size was composed by 672 hosts, collected between 2011-2013 from thefollowing reservoirs of Nuevo Leon, Mexico: Rodrigo Gomez dam ("La Boca", LB), Cuchillo Solidaridad dam(CS), Salinillas lagoon (LS), Mariano Escobedo dam ("Sombreretillo", S), and Jose Lopez Portillo dam ("CerroPrieto", CP). Living fish were transported to the laboratory; sizes and weights were then recorded to calculatethe Fulton condition factor (k). If possible, gender was also recorded. Parasites were detected under stereoscopy,recollected and preserved by traditional techniques. Statistical analysis of association between parasitic load,gender, and Fulton condition factor were calculated, using the X2 and the Student-t tests. Results showed that 12different metazoans were identified, two flukes (Posthodiplostomum minimum centrarchi and Phyllodistomumpearsei), one tapeworm (Proteocephalus ambloplitis), three roundworms (Contracaecum sp., Spinitectuscarolini and Philometra nodulosa), two acantocephalan (Neoechinorhynchus cylindratus and Arhythmorhynchussp.), one leech (Myzobdella moorei), and three copepods (Ergasilus versicolor; Ergasilus arthrosis and Ergasiluscerastes). HSD Tukey test showed that infected fish from LB were significantly different than LS, CS, CP,and S (P<0.05). Parasites most commonly collected in all five locations were P. m. centrarchi, Contracaecumsp. and E. versicolor. The frequency of P. m. centrarchi was highly significant (P<0.001) than other parasites;furthermore, this parasite showed the highest prevalence (97.5 %), abundance (10.12-83.6), and intensity(15.44-88.5). Statistical dependence was found between intensity and abundance of metazoans with regard tofemale gender and size on five reservoirs (t=143.82, P=0.0001; t=2.6, P=0.01, respectively). In addition, theabundance and intensity showed statistical dependence with regard to k, which was proportionally significant.New locality records for Nuevo Leon include P. m. centrarchi, P. pearsei, P. ambloplitis, Contracaecum sp.,Arhythmorhynchus sp., and E. cerastes. Furthermore, P. nodulosa, S. carolini, N. cylindratus, and E. arthrosiswere new records for Mexico. PMID- 29451756 TI - The diversity of ant communities (Hymenoptera: Formicidae) and their connections with other arthropods from three temperate forests of Central Mexico. AB - Ants have been considered useful for bioindication because of their ecological characteristics.Nonetheless, among the characteristics of a bioindicator group, there must be a consistent and replicableresponse to disturbance. In this sense, divergent reactions have been found, even between taxons narrowlyrelated. The objective of this work was to compare the diversity of the ant communities in three different temperateforests with different levels of disturbance, and to correlate their abundance and diversity of species, withthat found in other arthropod communities of the same forests. The work was carried out in three municipalitiesin the North of the State of Mexico, where three types of different forests were identified by their degree of disturbance.These types include: 1) primary forest (PF), with typical species of a conserved forest; 2) mixed forest(MF), with species of a conserved forest and a reforestation effort; and 3) reforested forest (RF), with speciesused in reforestation efforts and indicative of disturbance. In each sample, an area of 2 500 m2 was selected. Eacharea had 16 pitfalls apiece and they were placed 10 m away from each other. Samples were collected twice; onefrom February through March 2009 (dry season) and another from August through September 2010 (rainy season),which produced a total of 192 traps. Obtained specimens were identified at the most taxonomically specificlevel. All data captured was transformed to ?n + 0.5 and diversity index levels of Shannon and Simpson werecalculated, as well as richness of species for ants, beetles, grasshoppers, true bugs, and spiders. The values ofrichness, diversity, and abundance were correlated with the Pearson coefficient, and to evaluate possible causalrelationships between these, a path analysis was performed. Results suggested an important influence of the siteover ant communities, and values of richness, abundance and diversity were correlated with the communities ofspiders, beetles, grasshoppers and true bugs, but not for all the sites studied. Responses to environmental changesare not only on the numeric proportions of abundance, richness and diversity, but also in the indirect and casualecological interactions. Finally, the data seems to indicate that the responses of the ants to the environmentalchanges are not necessarily reflected on other organisms' communities, so the ants' role as bioindicators can belimited.

AB - The Northern Gulf of California (NGC) is a mega diverse area of highendemism with major economic interest because of the multi-specific fisheries developed, mainly shrimp.There is a lack of recent studies on bycatch fish assemblages, so during the fishing seasons from 2009-2010 and2010-2011, on board 13 shrimp boats, 14 commercial fishing trips were performed from 5 m - 90 m in depthwith a total of 119 catches. The 119 catches were analyzed to assess fish community structure using taxonomicdiversity indices to detect changes in the community following the taxonomic distinctness average Delta+ and thediversity index Delta* (TAXDEST of the PRIMER v6 program). To confirm the structure of functional groups, weconsidered similarities of ecologic and morphologic traits among species. The results showed that the indicesDelta+ and Delta* were within the expected average and confidence intervals at 95%, finding significant differencesbetween the indices. The analyses showed a well-structured community because of the great variety of formsand functions of the species within the community. In the community of the functional groups, reproduction wasthe ecological attribute that contributed the most to their structure. The community structure was represented byintermediate trophic levels (3-3.9), preferably primary and secondary carnivores within the trophic categories ofpredators of benthic ichthyo-fauna that belong to demersal species of soft bottoms and mostly fusiform body. Toconclude, the NGC showed high functional redundancy according to the estimated functional groups, thus theecosystem was considered stable and with great diversity. This type of studies should be followed using fishingand environmental effort due to the great biological and ecologic importance in the area.

AB - Fishes display diverse feeding strategies that may undergo modifications through ontogeny or seasonally with ecological implications in thefood webs. Even though the significance of fishes as top predators is recognized, the diet of many of them isstill scarcely known; especially in fish that inhabit shallow lakes densely vegetated. The aim of this study wasto investigate the diet of Characidium rachovii and Pyrrhulina australis of different size classes (I, II and III);during winter and summer, and estimate their trophic niche breadth. The field work was carried out in two shallowlakes fed by rain (Soto and Pampin lake, Corrientes province), from July 2011 to August 2012. The stomachcontents of 104 individuals of C. rachovii and 91 specimens of P. australis were examined. Accumulation curveshowed that the number of analyzed stomachs was representative for both species. Twenty three food itemsfor C. rachovii and twenty eight for P. australis were recognized in the gut contents. According to the index ofrelative importance (IRI), both species feed preferably on cladocerans and midges (Chironomidae), and bothspecies showed a large overlap in their diets (85 %), according to Morisita index. However the diversity of fooditems and the trophic niche breadth of P. australis (1D = 8.86; B = 4.76) were higher than C. rachovii (1D =3.37; B = 2.25). Significant differences were observed in the diet of three sizes of P. australis (chi2, p < 0.01) andbetween the sizes I and III of C. rachovii (chi2, p = 0.03). In both species the diversity of food items increased withincreasing their size. Between seasons, the diet differences were significant for both species (chi2, p < 0.0001).The high feeding overlap indicates that both species mostly use the same resources. Notwithstanding this, boththe number of food items as the diversity and breadth of the trophic niche, suggest that these species use differentfeeding strategies, C. rachovii showed a trend towards specialization in microcrustacean consumption; while P.australis exhibited a broader trophic spectrum, incorporating insects from littoral areas and from the terrestrialcommunity. The loss of the trophic dominant resource, by increasing urbanization on the margin of the studiedshallow lakes, could lead to increased competition, due to the wide diet overlap in both species.

AB - Arca zebra is a mollusk of commercial value and a major socioeconomic fishery in Northeastern Venezuela. The present study aimed to evaluate thereproductive effort (RE), fattening index (FI) and yield (Y) in different size groups of A. zebra from the morroChacopata, Venezuela. For this, monthly samplings from June 2008 and June 2009, were undertaken, and thebivalves obtained were distributed in three length groups: I (30.1 to 50.0 mm), II (50.1 to 70.0 mm) and III (>70.0 mm). Monthly RE, FI and Y were determined based on bivalve changes in volume of fresh meat (VFM),intervalvar volume (IV), dry gonad biomass (DW), dry biomass of the organism without gonad (DWs), freshbiomass of meat (FBM) and total biomass including shell (TBIS). Besides, environmental variables such astemperature, salinity, dissolved oxygen, total organic and inorganic seston and chlorophyll a were measuredmonthly. There was great variation in the DW between length groups (relevant for II and III): increased fromJune until late September 2008, was followed by a marked decrease in October 2008, recovered in the followingmonths, and decreased in January 2009, with a slight increase until May 2009; these changes were associatedwith variations in sea temperature. The weight of the gonad (DW) influenced the RE, FI and Y, as these reachedtheir peaks in the months where there was higher gonadal production, indicating the influence of temperature onA. zebra reproduction.

AB - The Andean mountain region of Colombia has a high diversity of fish,with high number of endemic species. To promote their protection and conservation, the knowledge of theirgeneral and reproductive biology is necessary. With this aim, the reproductive biology of Saccodon dariensis,in the Penoles and El Cardal creeks, Guatape River mid-basin, Magdalena River Basin, was studied, to determinereproductive differences between individuals with different oral polymorphism (morpho I vs. morpho IV,according to Roberts, 1974), and to define a possible spatial or temporal reproductive isolation. Ten field samplingswere carried out between October 2007 and February 2012, in periods of rain (October and November2007, May 2008 and November 2011), dry (January and March 2010, February 2012), transition from rain todry (June 2011) and transition from dry to rain (March 2008 and September 2011). Samples were caught usingelectrofishing equipment and cast nets (10 mm between knots). A total of 468 specimens were analyzed, 268of which were females and 200 males. The average catch size for the total number of individuals studied was109.6 mm SL (65.5-174.0 mm), with 108.0 mm SL for females (67.7-174.0) and 111.9 mm SL (65.5-149.4)for males. Females predominated in the catches, and the sex ratio of 1.0:1.34 significantly deviated from thetheoretical distribution 1:1. Similarly, morpho IV predominated in the catches, and morphs ratio was 1.00:1.48.Based on the monthly evolution of the gonadosomatic index (GSI) and the proportion of mature specimens, thespawning season occurs during periods of transition from dry to rainy season when water level begins to raise.The lowest values of the condition factor that match the maximum values of GSI, indicates that this speciesaccumulated body energy reserves that are used during the gonadal maturation and spawning. The mean sizeat sexual maturity (L50) was 88.8 mm SL in females and 109.3 mm SL in males. The fecundity of S. dariensisfluctuated between 1 137 and 39 303 (mean = 8 309, SD = 9 021) and the relative fecundity between 144 and1 131 oocytes/g of total weight (mean = 439 +/- 212). The diameter of the oocytes was 0.54 mm (SD = 0.07).Different development in oocytes was not observed, suggesting massive spawning. The coexistence of the twomorphs, external fertilization and simultaneous occurrence of reproductive peaks found in this study did notprovide support for a possible spatial or temporal reproductive isolation of morphotypes.

AB - Brazil holds most of the Atlantic Forest Domain and is also one of the Rubiaceae diversity centers inthe Neotropics. Despite the urban expansion in the state of Rio de Janeiro, large areas of continuous vegetationwith high connectivity degree can still be found. Recently, new Rubiaceae species have been described in the Riode Janeiro flora, which present small populations and very particular distribution. The current paper analyzedthe similarity in the floristic composition of the Rubiaceae in eight Atlantic Forest remnants of Rio de Janeirostate protected by Conservation Units. We also surveyed and set guidelines for conservation of microendemicspecies. The similarity analysis were based on previously published studies in Area de Protecao Ambientalde Grumari, Area de Protecao Ambiental Palmares, Parque Estadual da Serra da Tiririca, Parque Nacional doItatiaia, Parque Nacional de Jurubatiba, Reserva Biologica de Poco das Antas, Reserva Biologica do Tingua andReserva Ecologica de Macae de Cima - using the PAST software ("Paleontological Statistics") with Sorensencoefficient. The floristic similarity analysis revealed two groups with distinct physiographic characteristics anddifferent vegetation types. Group A consisted in two Restinga areas, Area de Protecao Ambiental de Grumariand Parque Nacional de Jurubatiba, which showed strong bootstrap support (98 %). Group B included forestremnants with distinct phytophisiognomies or altitudes, but with moderate bootstrap support. Low similaritylevels among the eight areas were found due to the habitats' heterogeneity. The current study pointed out 19microendemic species from the Atlantic Forest, they present a single-site distribution or a distribution restrictedto Mountain and Metropolitan regions of Rio de Janeiro state. Concerning the conservation status of microendemicspecies, discrepancies between the Catalogue of Flora of Rio de Janeiro and the Red Book of BrazilianFlora (two of the main reference catalogs of Brazilian flora) have been identified. We have also highlighted theneed for recollecting microendemic species from the Atlantic Forest, and for properly assessing the degree ofthreat faced by these taxons early.

AB - The Caribbean King Crab, Damithrax spinosissimus is a fishery resource, butfew biological studies are available. Its patchy distribution, and the high environmental heterogeneity due to theoceanographic, landscape, and ecological characteristics of the Caribbean Sea, can favor the phenotypic variabilityaccording to the geographic origin. For this reason, the objective of our study was to determine morphometicvariability in the carapace of the crabs from three Southwestern Caribbean islands: Providence, Rosario and SanBernardo. The former has an oceanic influence, whereas the two latter islands, which are closer to the mainland,have more influence of the coastal dynamic. A total of 276 individuals from the three islands were captured andphotographed: 103 females and 173 males; their variation was analyzed from 12 anatomical landmarks markedon one half of the carapace. The differences in the carapace size were calculated using a Fisher's pairwise comparison;the allometric effect was calculated by Multivariate Regression Analysis; and the Allometric model viaMultivariate Analysis of Covariance. The average shape was calculated from the relative wraps RW obtainedthrough PCA analysis; and the Euclidian distances between the shape averages, were used to construct a treeusing the Neighbour-Joining algorithm over 10 000 permutations. The results showed significant differences inthe size and shape of the carapace between sexes and among the three islands. The differences in the shape ofthe crabs from Providencia were significantly greater than those found between the crabs of Rosario and SanBernardo. These results can be explained inclusively due to the genetic differences and phenotypic plasticity, dueto environmental heterogeneity of the sector. This study, the first of its kind, is a contribution to the knowledgeof the species. We concluded that different management strategies should be differently adopted in each of thethree studied islands.

AB - Fish by-catch of shrimp fishery from the Gulf of Tehuantepec is composed of several species that aremainly discarded. In this study, fish by-catch species composition, distribution and biogeographical affinitieswere analyzed. For this, a total of 15 cruises were carried out on the continental shelf, at depths from 15 to 64 m,during 2003, 2004, 2005 and 2013. Results showed that fish by-catch was represented by 58 families, 129 generaand 242 species. The families Haemulidae, Sciaenidae, Paralichthyidae, Gerreidae and Carangidae accounted for> 70 % of the catch. Haemulopsis axillaris, Syacium ovale, Selene peruviana, Diapterus peruvianus, Larimusacclivins and Stellifer erycimba were the most frequent species at < 40 m depth (inner shelf), and Prionotusstephanophrys, Scorpaena russula, Porichthys analis and Synodus scituliceps were dominant at 40 60 m depth(outer shelf). Analysis of biogeographical affinities showed that 36.1 % of species had a wide distribution, fromSan Diego Province to the Panamic Province, while 13.2 % had a restricted distribution in the Mexican andPanamic Provinces. The ichthyofaunal composition was markedly influenced by the local environment andseasonal conditions. PMID- 29451764 TI - Interactions between frugivorous bats (Chiroptera: Phyllostomidae) and Piper tuberculatum (Piperaceae) in a tropical dry forest in Valle del Cauca, Colombia. AB - In any ecosystem, fruits are resources that vary in time and space as well as in nutritional content.Coexistence of species from a trophic guild depends on the division and use of resources. Therefore, the organismsthat depend on them as a food source, tend to show a certain degree of specialization. This way, understandingthe factors that influence the dynamics of seed dispersal is important for the regeneration and conservationof tropical ecosystems. Our aim was to determine variation in consumption of Piper tuberculatum by fruit batassemblages in the village of Robles (Jamundi, Valle del Cauca, Colombia). P. tuberculatum is a resource usednot only by wildlife but also by people in the village of Robles. Bats were captured in mist nets between June andNovember 2014, their feces were collected, and the length of the forearm, wing area, leg length and mass wererecorded. At the Universidad del Valle seed laboratory, fecal samples were washed, and their content determined.Of the 14 species captured, Sturnira lilium, Carollia brevicauda, Carollia perspicillata and Artibeus lituratusshowed signs of having consumed P. tuberculatum. Sturnira lilium was the main consumer of P. tuberculatumfruits, with the greatest number of consumption events of fruit from this plant species, whereas the other batsshowed more diversified consumption events. The greatest niche overlap was recorded between C. brevicaudaand C. perspicillata, species that showed similar sizes (i.e., wing area and forearm length) followed by S. liliumand C. perspicillata. In contrast, A. lituratus showed the least niche overlap with the other three fruit bats captured.In conclusion, Sturnira lilium showed an interaction Sturnira-Piper, which is the result of low Solanumavailability, and this bat species was the largest consumer of P. tuberculatum in the region.

AB - Ecological studies of species, such as the stomach content analysis, allow us to recognize differenttrophic groups, the importance of trophic levels and the interrelationships among species and other members ofthe community. In this investigation, we studied food habits, feeding variation and trophic relationships of thefishes present in streams of the Corral de San Luis drainage, Tubara, Atlantico Department, a part of the lowerMagdalena River Basin in Colombian Caribbean. Fish samples of Awaous banana, Agonostomus monticola,Andinoacara latifrons, Hyphessobrycon proteus, Poecilia gillii, Gobiomorus dormitor and Synbranchus marmoratuswere obtained using a seine (2x5 m, mesh 0.5 cm), from November 2012 to October 2013. To analyzetheir stomach contents, we used numeric (% N), volumetric (% V) and frequency of occurrence (% FO) methods,an emptiness coefficient (C.V), index of food item importance (I.A). Besides, physical and chemical habitatparameters were recorded on site. Information obtained was processed using multivariate statistical analysis,ecological indices, and null models: canonical correspondence analysis (CCA), principal component analysis(PCA), trophic niche amplitude (Shannon-Weaver H') and trophic overlap (Morisita-Horn). We observed significantdifferences on food resources consumption (K-W= 20.86; p<0.05) among the studied species. Theywere classified according to their food habits as omnivores with a tendency towards insectivory (A. monticolaH'0.60; A. latifrons H'0.43), herbivores with a tendency towards the consumption of algae (A. banana H'0.50;P. gillii H'0.54) and carnivores with a tendency towards insectivory (H. proteus H'0.23); benthic invertebratesand microalgae were found the most important food sources. A total of 65 food items were identified in thisstudy: 21 for A. banana (2 unique, 19 shared), 40 for A. monticola (21 unique, 19 shared), 19 for A. latifrons (5unique, 14 shared), 6 for H. proteus (1 unique, 5 shared) and P. gillii with 28 (4 unique, 24 shared). The canonicalcorrespondence analysis showed that water conductivity, salinity and pH were the variables that directlyinfluenced fish community structure at the sampled sites. The null model analyses showed that the group offishes was significantly segregated (p= 0.001) along the trophic axis, with respect to shared food items, and thatthe segregation was not influenced or generated by competition. The Morisita-Horn index showed false trophicoverlap (similarity of about 80 %) between A. banana and P. gillii. The first component of the PCA analysis wasexplained mainly by phytoplankton, and component two was correlated with items of animal origin. The fishesassociated with PC1 were P. gillii and A. banana, with high ingestion values of microalgae. PC2 was explainedby A. monticola with high numbers of food items of animal origin. The group of fishes studied behaved as anassemblage; given that the trophic interrelationships showed false trophic overlap, and that they did not excludeone another from the ecosystems, but instead, used different food resources and different physical spaces withintheir habitat.

AB - Pasteurella multocida is an important veterinary pathogen causing infections in animals and birds.Nowadays, different reports have described the severity of infections, increasing resistance of micro-organismsto antibiotics, and the contribution of ethnoveterinary practices towards the treatment of various ailments ofanimals. The aim of the present study was to investigate the antibacterial efficacy of the ethanolic extracts ofendophytic fungi against P. multocida Capsular Type A strains. A total of six endophytic fungi were isolatedfrom two tropical ethnoveterinary plants: Garcinia xanthochymus H. and Polygonum chinense L. The ethanolicextracts of the endophytic fungi were subjected to in vitro antimicrobial activity by the well diffusion method.Besides, we evaluated the treatment of mice with the potent fungal extract and observed the effects in differentorgans under electron microscopy. Our results showed that four fungi had antimicrobial activity against theselected pathogen. The best antibacterial activity was showed by the extract of the endophytic fungi, Glomerellamagna isolated from G. xanthochymus, with a minimum inhibitory concentration of 46.9 MUg/mL and minimumbactericidal concentration of 750 MUg/mL. Treatment of mice with the potent fungal extract caused a considerableinhibitory effect on the pathogen growth in vital organs, results that was also confirmed by histopathologicalstudies made by scanning electron microscopy. The present findings indicated that the endophytic fungi G.magna has the potential to provide an effective treatment against infections caused by Pasteurella multocida.However, the isolation of bioactive components needs further investigation.

The macroinvertebratesare a vital component of freshwater ecosystems as they contribute to the process of organic matter whileserving as food for other organisms such as fish and amphibians. Unfortunately, the knowledge of the aquaticdiversity is poor in the high Andean systems (between 3 200 and 5 200 m.a.s.l. and rainfall below 300 mm peryear), especially in the Argentinean peatbogs, a fact which has made difficult the interpretation of spatial patternson a regional scale. The present study aimed to describe the composition of aquatic macroinvertebrates in sevenpeatbogs in the Argentinean Puna, and to analyze for the first time their spatial patterns. For this, we studiedthe relationship of these organisms with the environment, and obtained information about the surrounding vegetationand water physico-chemical characteristics. A total of 3 131 specimens of aquatic macroinvertebrateswere collected, representing 25 taxa belonging to 22 families and 24 genera. In addition, 62 species of vascularplants were recorded, belonging to 20 families. The most abundant life form were the tufted grasses, followedby cushions. By using an NMDS (Non-Metrical Multidimensional Scaling) statistical analysis, the samplingsites were ordered in each peatbog as follows. The peatbogs located furthest West and South with higher watertemperature were grouped on axis 1, whereas those with higher conductivity, whole water dissolved solidsand salt concentration were grouped on axis 2. The water temperature was higher than air temperature at alltimes, and we found no association between temperature and altitude. The altitude had no correlation with theabundance of macroinvertebrates or with plant richness. Life forms such as scattered graminoids, trailing andprostrate herbs (in many cases they get into the channel) and aquatic plants were more abundant in peatbogs 4,5 and 7 and they had a correlation with some macroinvertebrates belonging to functional trophic groups suchas filter-collectors, collectors and scrapers. Finally, conductivity, whole dissolved solids and salt concentrationhad their highest value in peatbog 6, where Bivalvia (filter-collector) and Hyalella (collector) were also found.The results obtained attest that these macroinvertebrates displayed diversity and composition spatial patterns,the most important feature being their relationship with the surrounding vegetation, and to a lesser extent, withthe physical and chemical traits of water in seven fertile lowlands in the Argentinean Puna.

AB - Human pressure on natural habitats increases the importance of agroforests for biodiversity conservation.The objective of this study was to evaluate the role of cacao traditional cultivation system (CTCS) onthe conservation of the herbivorous insect community when compared with a monodominant rubber agroforest,a type of agricultural system for cacao cultivation. The insects were sampled in three habitats in SoutheasternBahia, Brazil: native forests, CTCS and rubber agroforests. In each habitat, 18 plots of 10 m2 were established,and the structural measures were collected and herbivorous insects were sampled with a Malaise/window trap.The diversity of folivorous decreased with the simplification of vegetation structure, but species compositionwas similar among habitats. In addition to a decrease in the availability of resources in monodominant rubberagroforests, the latex present in these systems have limited the occurrence of species that cannot circumventlatex toxicity. The diversity of sap-sucking insects was similar among habitats, but species composition wassimilar only in the CTCS and native forest, and it was different in the rubber agroforest. We observed turnoverand a higher frequency of individuals of the family Psyllidae in the rubber agroforest. The biology and behaviorof Psyllids and absence of natural enemies enable their diversity to increase when they are adapted to a new host.We observed a shift in the composition of xylophagous insects in the rubber agroforest compared to that in otherhabitats. Moreover, this agroforest has low species richness, but high individual abundance. Latex extraction islikely an important additional source of volatile compounds discharged into the environment, and it increasesthe attraction and recruitment of coleoborers to these sites. We concluded that CTCS has an herbivorous insectcommunity with a structure similar to the community found in native forests of the region, and they present amore interesting conservation strategy when compared to rubber agroforests. We also emphasized the potentialrisk of local pest outbreaks in rubber agroforests for both the rubber and associated cacao trees.

AB - The use of direct response of animals to environmental challenges by production of biomarkers isa better tool to assess environmental pollution than the conventional methods. This study aimed to measureGlutathione-S-transferase (GST) in earthworms as tools for assessing heavy metal pollution in abattoir soil.Five (5) replicates each of earthworm species (Libyodrilus violaceous, Eudrilus eugeniae and Alma millsoni),soil and rumen waste samples were collected from three (3) abattoir sites (Lafenwa, Gbonogun and Madojutimiabattoirs), and a control site located within Federal University of Agriculture Abeokuta, beside an undisturbedstream with no rumen waste. Heavy metal (Cu, Zn, Pb, Cd, Co, Cr, Ni and Mn) concentrations in rumen waste,abattoir soils and earthworm tissues were determined using Atomic Absorption Spectrophotometer. The pH andorganic matter (OM) concentrations of the rumen waste and abattoir soils were determined by standard methods.GST activities in the earthworm tissues were determined through the conjugation of 1 mM reduced glutathione(GSH) with 1 mM 1-chloro-2,4 dinitrobenzene (CDNB). The rumen waste recorded significantly higher (p <=0.05) % OM, heavy metal concentrations and pH level than in their respective abattoir soils. The mean heavymetal concentrations of Cu, Zn, Pb, Cd and Mn were highest in the tissue of earthworm species obtained fromLafenwa abattoir. A significantly (p <= 0.05) higher GST activities were recorded in the tissue of earthwormspecies obtained from Lafenwa and Gbonogun abattoirs. Libyodrilous violaceus obtained from Lafenwa abattoirrecorded the highest GST activity (8.47+/-1.39) in their tissue followed by the ones from Gbonogun abattoir(8.21+/-0.85). A significant (p <= 0.05) positive correlations was observed between GST activities in earthwormtissues and heavy metal concentrations. GST activities can therefore be used to assess the level of heavy metalpollution in abattoir soils. PMID- 29451770 TI - Thermodynamic and Kinetic Effects in the Crystallization of Metal-Organic Frameworks. AB - The evolution of metal-organic frameworks (MOFs) has been one of the most exciting aspects of materials chemistry over the last 20 years. In this Account, we discuss the development during this period in our understanding of the factors that control the crystallization of MOFs from solution. Both classical porous MOFs and dense MOF phases are considered. This is an opportune time at which to examine this complex area because the experimental tools now available to interrogate crystallization processes have matured significantly in the last 5 years, particularly with the use of in situ synchrotron X-ray diffraction. There have also been impressive developments in the use of density functional theory (DFT) to treat not only the energies of very complex structures but also their entropies. This is particularly important in MOF frameworks because of their much greater flexibility compared with inorganic structures such as zeolites. The first section of the Account describes how early empirical observations on the crystallization of dense MOFs pointed to a strong degree of thermodynamic control, with both enthalpic and entropic factors playing important roles. For example, reactions at higher temperatures tend to lead to denser structures with higher degrees of framework connectivity and lower levels of solvation, and polymorphs tend to form according to their thermodynamic stabilities. In the case of metal tartrates, these trends have been validated by calorimetric studies. It has been clear for more than a decade, however, that certain phases crystallize under kinetic control, especially when a change in conformation of the ligand or coordination around a metal center might be necessary to form the thermodynamically preferred product. We describe how this can lead to time dependent crystallization processes that evolve according to the Ostwald rule of stages and can be observed by in situ methods. We then consider the crystallization of porous MOFs, which presents additional challenges because of solvation effects. In spite of these problems, much has been learned about the energetics of the underlying frameworks, where the relationship between porosity and stability initially seemed to mirror the behavior of zeolites, with more porous structures being less stable. Recently, however, this simple relationship has had to be reconsidered with the emergence of some very flexible structures wherein the open structures are more stable than their denser analogues at finite temperatures because of their large vibrational entropies. In the final section we describe how the concepts developed in the MOF work have been extended into the closely related area of hybrid organic-inorganic perovskites. We describe recent studies on polymorphism in hybrid perovskites, which is amenable to total free energy calculations using a combination of DFT and lattice dynamics methods.

AB - The programmability of DNA enables constructing nanostructures with almost any arbitrary shape, which can be decorated with many functional materials. Moreover, dynamic structures can be realized such as molecular motors and walkers. In this work, we have explored the possibility to synthesize the complementary sequences to single-stranded gap regions in the DNA origami scaffold cost effectively by a DNA polymerase rather than by a DNA synthesizer. For this purpose, four different wireframe DNA origami structures were designed to have single-stranded gap regions. This reduced the number of staple strands needed to determine the shape and size of the final structure after gap filling. For this, several DNA polymerases and single-stranded binding (SSB) proteins were tested, with T4 DNA polymerase being the best fit. The structures could be folded in as little as 6 min, and the subsequent optimized gap-filling reaction was completed in less than 3 min. The introduction of flexible gap regions results in fully collapsed or partially bent structures due to entropic spring effects. Finally, we demonstrated structural transformations of such deformed wireframe DNA origami structures with DNA polymerases including the expansion of collapsed structures and the straightening of curved tubes. We anticipate that this approach will become a powerful tool to build DNA wireframe structures more material efficiently, and to quickly prototype and test new wireframe designs that can be expanded, rigidified, or mechanically switched. Mechanical force generation and structural transitions will enable applications in structural DNA nanotechnology, plasmonics, or single-molecule biophysics. PMID- 29451772 TI - Ultraflexible and High-Performance Multilayer Transparent Electrode Based on ZnO/Ag/CuSCN. AB - Driven by huge demand for flexible optoelectronic devices, high-performance flexible transparent electrodes are continuously sought. In this work, a flexible multilayer transparent electrode with the structure of ZnO/Ag/CuSCN (ZAC) is engineered, featuring inorganic solution-processed cuprous thiocyanate (CuSCN) as a hole-transport antireflection coating. The ZAC electrode exhibits an average transmittance of 94% (discounting the substrate) in the visible range, a sheet resistance ( Rsh) of 9.7 Omega/sq, a high mechanical flexibility without Rsh variation after bending 10 000 times, a long-term stability of 400 days in ambient environment, and a scalable fabrication process. Moreover, spontaneously formed nanobulges are integrated into ZAC electrode, and light outcoupling is significantly improved. As a result, when applied into super yellow-based flexible organic light-emitting diode, the ZAC electrode provides a high-current efficiency of 23.4 cd/A and excellent device flexibility. These results suggest that multilayer thin films with ingenious material design and engineering can serve as a promising flexible transparent electrode for optoelectronic applications.

AB - The surface chemistry and the Cr tolerance ability of oxygen electrodes play a vital role in the performance and long-term stability of solid oxide cells (SOCs). In this paper, the surface cation segregations on the double-perovskite oxide PrBaCo2O5+delta (PBCO) and its relationship with Cr deposition are reported. During high-temperature annealing in an O2 atmosphere, the elements Ba and Co diffuse out of the lattice and form many BaO and Co3O4 precipitates on the surface, mainly located at grain boundaries. In the presence of volatile Cr species, the observation of BaCrO4, but not CoCr2O4, on a segregated PBCO surface reveals that the Cr deposition preferentially takes place on segregated BaO rather than on Co3O4 precipitates. Our results show that segregated BaO precipitates are very active toward Cr vapor and PBCO is not a Cr-tolerant oxygen electrode for SOCs operating at high temperatures, despite its superior electrochemical performance. PMID- 29451774 TI - Organic Semiconducting Photoacoustic Nanodroplets for Laser-Activatable Ultrasound Imaging and Combinational Cancer Therapy. AB - Combination of photoacoustic (PA) and ultrasound (US) imaging offers high spatial resolution images with deep tissue penetration, which shows great potential in applications in medical imaging. Development of PA/US dual-contrast agents with high contrast and excellent biocompatibility is of great interest. Herein, an organic semiconducting photoacoustic nanodroplet, PS-PDI-PAnD, is developed by stabilizing low-boiling-point perfluorocarbon (PFC) droplet with a photoabsorber and photoacoustic agent of perylene diimide (PDI) molecules and coencapsulating the droplet with photosensitizers of ZnF16Pc molecules. Upon irradiation, the PDI acts as an efficient photoabsorber to trigger the liquid-to-gas phase transition of the PFC, resulting in dual-modal PA/US imaging contrast as well as photothermal heating. On the other hand, PFC can serve as an O2 reservoir to overcome the hypoxia-associated resistance in cancer therapies, especially in photodynamic therapy. The encapsulated photosensitizers will benefit from the sustained oxygen release from the PFC, leading to promoted photodynamic efficacy regardless of pre-existing hypoxia in the tumors. When intravenously injected into tumor-bearing mice, the PS-PDI-PAnDs show a high tumor accumulation via EPR effect. With a single 671 nm laser irradiation, the PS-PDI-PAnDs exhibit a dual modal PA/US imaging-guided synergistic photothermal and oxygen self-enriched photodynamic treatment, resulting in complete tumor eradication and minimal side effects. The PS-PDI-PAnDs represents a type of PFC nanodroplets for synergistic PDT/PTT treatment upon a single laser irradiation, which is expected to hold great potential in the clinical translation in dual-modal PA/US imaging-guided combinational cancer therapy. PMID- 29451775 TI - Fluorescence Imaging of Huntingtin mRNA Knockdown. AB - Huntington's disease (HD) is an autosomal-dominant neurodegenerative genetic disorder caused by CAG repeat expansion in exon 1 of the HTT gene. Expression of the mutant gene results in the production of a neurotoxic polyglutamine (polyQ) expanded huntingtin (Htt) protein. Clinical trials of knockdown therapy of mutant polyglutamine-encoding HTT mRNA in Huntington's disease (HD) have begun. To measure HTT mRNA knockdown effectiveness in human cells, we utilized a fluorescent hybridization imaging agent specific to the region encompassing the human HTT mRNA initiation codon. We designed, synthesized, purified, and characterized Cal560-spacer-peptide nucleic acid (PNA)-spacer-IGF1 tetrapeptides. The human HTT PNA 12mer complement was CATGGCGGTCTC, while the rat htt equivalent 12mer contained the sequence CATGaCGGcCTC, with two bases differing from the human sequence. The cyclized IGF1 tetrapeptide fragment d(CSKC) that promotes IGF1 receptor-mediated endocytosis was bonded to the C-terminus. We tested the reliability of HTT mRNA imaging with Cal560-spacer-peptide nucleic acid (PNA) spacer-IGF1 tetrapeptides in human embryonic kidney (HEK) 293T cells that express endogenous HTT and IGF1 receptor. By qPCR, we quantitated HTT mRNA in HEK293T cells with and without HTT mRNA knockdown by three different siRNAs. By confocal fluorescence imaging, we quantitated the accumulation of fluorescent HTT hybridization agent in the same cells. A rat homologue differing from the human sequence by two bases showed negligible fluorescence. qPCR indicated 86 +/- 5% knockdown of HTT mRNA by the most effective siRNA. Similarly, Cal560- HTT PNA peptide fluorescence intensity indicated 69 +/- 6% reduction in HTT mRNA. We concluded that the fluorescence hybridization method correlates with the established qPCR method for quantitating HTT mRNA knockdown by siRNA in HEK293T cells, with a Pearson correlation coefficient of 0.865 for all three siRNA sequences. These results will enable real time imaging and quantitation of HTT mRNA in animal models of HD. PMID- 29451776 TI - Short-Term Pulmonary Toxicity Assessment of Pre- and Post-incinerated Organomodified Nanoclay in Mice. AB - Organomodified nanoclays (ONCs) are increasingly used as filler materials to improve nanocomposite strength, wettability, flammability, and durability. However, pulmonary risks associated with exposure along their chemical lifecycle are unknown. This study's objective was to compare pre- and post-incinerated forms of uncoated and organomodified nanoclays for potential pulmonary inflammation, toxicity, and systemic blood response. Mice were exposed via aspiration to low (30 MUg) and high (300 MUg) doses of preincinerated uncoated montmorillonite nanoclay (CloisNa), ONC (Clois30B), their respective incinerated forms (I-CloisNa and I-Clois30B), and crystalline silica (CS). Lung and blood tissues were collected at days 1, 7, and 28 to compare toxicity and inflammation indices. Well-dispersed CloisNa caused a robust inflammatory response characterized by neutrophils, macrophages, and particle-laden granulomas. Alternatively, Clois30B, I-Clois30B, and CS high-dose exposures elicited a low grade, persistent inflammatory response. High-dose Clois30B exposure exhibited moderate increases in lung damage markers and a delayed macrophage recruitment cytokine signature peaking at day 7 followed by a fibrotic tissue signature at day 28, similar to CloisNa. I-CloisNa exhibited acute, transient inflammation with quick recovery. Conversely, high-dose I-Clois30B caused a weak initial inflammatory signal but showed comparable pro-inflammatory signaling to CS at day 28. The data demonstrate that ONC pulmonary toxicity and inflammatory potential relies on coating presence and incineration status in that coated and incinerated nanoclay exhibited less inflammation and granuloma formation than pristine montmorillonite. High doses of both pre- and post-incinerated ONC, with different surface morphologies, may harbor potential pulmonary health hazards over long term occupational exposures. PMID- 29451778 TI - Rapid-Forming and Self-Healing Agarose-Based Hydrogels for Tissue Adhesives and Potential Wound Dressings. AB - To meet the progressive requirements of advanced engineering materials with superior physicochemical performances, self-healing and injectable hydrogels (AD hydrogels) based on agarose with pH-response were prepared through dynamic covalent Schiff-base linkages by simply mixing nontoxic agarose-ethylenediamine conjugate (AG-NH2) and dialdehyde-functionalized polyethylene glycol (DF-PEG) solutions. The self-healing and injectable capabilities of the hydrogels without any external stimulus are ascribed to dynamic covalent Schiff-base linkages between the aldehyde groups of DF-PEG and amine groups on AG-NH2 backbone. It is demonstrated that the AD hydrogels possess interconnected porous morphologies, rapid gelation time, excellent deformability, and good mechanical strength. The incorporated Schiff's base imparts the hydrogels to the remarkable tissue adhesiveness. In vivo hemostatic tests on rabbit liver demonstrate that the hydrogels are able to stanch the severe trauma effectively. Compared with the conventional gauze treatment, the total amount of bleeding sharply declined to be (0.19 +/- 0.03) g, and hemostasis time was strikingly shorter than 10 s after treating with AD hydrogels. In summary, the self-healing ability, cytocompatibility, and adhesion characteristic of the pH-responsive hydrogels make them promising candidates for long-lived wound dressings in critical situations.

AB - Drug resistance and relapse is common in cancer treatments with chemotherapeutics, and while drug combinations with naturally occurring, differentiation-inducing retinoic acid (RA) provide remission-free cures for one type of liquid tumor, solid tumors present major problems for delivery. Here, inspired by filoviruses that can be microns in length, flexible filomicelles that self-assemble from an amphiphilic block copolymer (PEG-PCL) are shown to effectively deliver RA and paclitaxel (TAX) to several solid tumor models, particularly in the liver. These hydrophobic compounds synergistically load into the cores of the elongated micelles, and the coloaded micelles prove most effective at causing cell death, ploidy, and durable regression of tumors compared to free drugs or to separately loaded drugs. RA-TAX filomicelles also reduce mortality of human lung or liver derived cancers engrafted at liver, intraperitoneal, and subcutaneous sites in immunodeficient mice. In vitro studies show that the dual drug micelles effectively suppress proliferation while upregulating a generic differentiation marker. The results highlight the potency of dual-loaded filomicelles in killing cancer cells or else driving their differentiation away from growth. PMID- 29451779 TI - Real-Time Intrinsic Fluorescence Visualization and Sizing of Proteins and Protein Complexes in Microfluidic Devices. AB - Optical detection has become a convenient and scalable approach to read out information from microfluidic systems. For the study of many key biomolecules, however, including peptides and proteins, which have low fluorescence emission efficiencies at visible wavelengths, this approach typically requires labeling of the species of interest with extrinsic fluorophores to enhance the optical signal obtained - a process which can be time-consuming, requires purification steps, and has the propensity to perturb the behavior of the systems under study due to interactions between the labels and the analyte molecules. As such, the exploitation of the intrinsic fluorescence of protein molecules in the UV range of the electromagnetic spectrum is an attractive path to allow the study of unlabeled proteins. However, direct visualization using 280 nm excitation in microfluidic devices has to date commonly required the use of coherent sources with frequency multipliers and devices fabricated out of materials that are incompatible with soft lithography techniques. Here, we have developed a simple, robust, and cost-effective 280 nm LED platform that allows real-time visualization of intrinsic fluorescence from both unlabeled proteins and protein complexes in polydimethylsiloxane microfluidic channels fabricated through soft lithography. Using this platform, we demonstrate intrinsic fluorescence visualization of proteins at nanomolar concentrations on chip and combine visualization with micron-scale diffusional sizing to measure the hydrodynamic radii of individual proteins and protein complexes under their native conditions in solution in a label-free manner. PMID- 29451781 TI - Multiple SNPs Detection Based on Lateral Flow Assay for Phenylketonuria Diagnostic. AB - Single nucleotide polymorphisms (SNPs) are closely related to genetic diseases, but current SNP detection methods, such as DNA microarrays that include tedious procedures and expensive, sophisticated instruments, are unable to perform rapid SNPs detection in clinical practice, especially for those multiple SNPs related to genetic diseases. In this study, we report a sensitive, low cost, and easy-to use point-of-care testing (POCT) system formed by combining amplification refractory mutation system (ARMS) polymerase chain reaction with gold magnetic nanoparticles (GMNPs) and lateral flow assay (LFA) noted as the ARMS-LFA system, which allow us to use a uniform condition for multiple SNPs detection simultaneously. The genotyping results can be explained by a magnetic reader automatically or through visual interpretation according to the captured GMNPs probes on the test and control lines of the LFA device. The high sensitivity (the detection limit of 0.04 pg/MUL with plasmid) and specificity of this testing system were found through genotyping seven pathogenic SNPs in phenylalanine hydroxylase gene ( PAH, the etiological factor of phenylketonuria). This system can also be applied in DNA quantification with a linear range from 0.02 to 2 pg/MUL of plasmid. Furthermore, this ARMS-LFA system was applied to clinical trials for screening the seven pathogenic SNPs in PAH of 23 families including 69 individuals. The concordance rate of the genotyping results detected by the ARMS LFA system was up to 97.8% compared with the DNA sequencing results. This method is a very promising POCT in the detection of multiple SNPs caused by genetic diseases. PMID- 29451782 TI - Molecular Recognition with Resorcin[4]arene Cavitands: Switching, Halogen-Bonded Capsules, and Enantioselective Complexation. AB - The development of synthetic host-guest chemistry to investigate and quantify weak, non-covalent interactions has been key to unraveling the complexity of molecular recognition in chemical and biological systems. Macrocycles have shown great utility in the design of receptors, enabling the development of highly preorganized structures. Among macrocycles, resorcin[4]arene-based cavitands have become privileged scaffolds due to their synthetic tunability, which allows access to structures with precisely defined geometries, as well as receptors that display conformational switching between two distinct states with a large difference in guest-binding properties. Here, we highlight three case studies demonstrating redox- and photoredox-controlled switching of molecular recognition properties, the formation of guest-binding supramolecular capsules based solely on halogen-bonding interactions, and enantioselective encapsulation of chiral, substituted cyclohexanes by enantiopure cage compounds as a result of perfect shape complementarity, dispersion interactions, and halogen bonding. The high geometrical and conformational control that can be achieved with resorcin[4]arene derived host systems will continue to be a powerful resource in future molecular recognition studies. PMID- 29451780 TI - Using in Vitro Evolution and Whole Genome Analysis To Discover Next Generation Targets for Antimalarial Drug Discovery. AB - Although many new anti-infectives have been discovered and developed solely using phenotypic cellular screening and assay optimization, most researchers recognize that structure-guided drug design is more practical and less costly. In addition, a greater chemical space can be interrogated with structure-guided drug design. The practicality of structure-guided drug design has launched a search for the targets of compounds discovered in phenotypic screens. One method that has been used extensively in malaria parasites for target discovery and chemical validation is in vitro evolution and whole genome analysis (IVIEWGA). Here, small molecules from phenotypic screens with demonstrated antiparasitic activity are used in genome-based target discovery methods. In this Review, we discuss the newest, most promising druggable targets discovered or further validated by evolution-based methods, as well as some exceptions. PMID- 29451783 TI - SuFEx Click Chemistry Enabled Late-Stage Drug Functionalization. AB - Sulfur(VI) Fluoride Exchange (SuFEx) is a new family of click chemistry transformations which relies on readily available materials to produce compounds bearing the SVI-F motif. The potential of SuFEx in drug discovery has just started to be explored. We report the first method of SuFEx chemistry for the conversion of phenolic compounds to their respective arylfluorosulfate derivatives in situ in 96-well plates. This method is compatible with automated synthesis and screening to quickly assess the biological activities of the in situ generated, crude products. Using this method, we perform late-stage functionalization of a panel of known anticancer drugs to generate the corresponding arylfluorosulfates. These in situ generated arylfluorosulfates are directly tested in a cancer-cell growth inhibition assay in parallel with their phenolic precursors. We discover three arylfluorosulfates that exhibit improved anticancer cell proliferation activities compared to their phenol precursors. Among these three compounds, the fluorosulfate derivative of Fulvestrant possesses significantly enhanced activity to down-regulate estrogen receptor (ER) expression in ER+ breast cancer cell line MCF-7 and the fluorosulfate derivative of Combretastatin A4-a general anticancer drug currently being evaluated under clinical trials-exhibits a 70-fold increase in potency in the drug resistant colon cancer cell line HT-29. PMID- 29451785 TI - Structure-Function Evaluation of Imidazopyridine Derivatives Selective for delta Subunit-Containing gamma-Aminobutyric Acid Type A (GABAA) Receptors. AB - delta-Selective compounds 1 and 2 (DS1, compound 22; DS2, compound 16) were introduced as functionally selective modulators of delta-containing GABA type A receptors (GABAAR). In our hands, [3H]EBOB-binding experiments with recombinant GABAAR and compound 22 showed no proof of delta-selectivity, although there was a minimally higher preference for the alpha4beta3delta and alpha6beta2/3delta receptors with respect to potency. In order to delineate the structural determinants of delta preferences, we synthesized 25 derivatives of DS1 and DS2, and investigated their structure-activity relationships (SAR). Four of our derivatives showed selectivity for alpha6beta3delta receptors (29, 38, 39, and 41). For all of them, the major factors that distinguished them from compound 22 were variations at the para-positions of their benzamide groups. However, two compounds (29 and 39), when tested in the presence of GABA, revealed effects at several additional GABAAR. The newly synthesized compounds will still serve as useful tools to investigate alpha6beta3delta receptors. PMID- 29451784 TI - Alteration of Crop Yield and Quality of Wheat upon Exposure to Silver Nanoparticles in a Life Cycle Study. AB - As a result of the rapid development of nanotechnology, metal-based nanoparticles (NPs) are inadvertently released into the environment and may pose a potential threat to the ecosystem. However, information for food quality and safety in NP treated crops is limited. In the present study, wheat ( Triticum aestivum L.) was grown in different concentrations of Ag-NP-amended soil (20, 200, and 2000 mg kg 1) for 4 months. At harvest, physiological parameters, Ag and micronutrient (Fe, Cu, and Zn) contents, and amino acid and total protein contents were measured. Results showed that, with increasing the exposure doses, Ag NPs exhibited severe phytotoxicity, including lower biomass, shorter plant height, and lower grain weight. Ag accumulation in roots was significantly higher than that in shoots and grains. Decreases in the content of micronutrients (Fe, Cu, and Zn) in Ag-NP treated grains suggested low crop quality. The results of amino acid and protein contents in Ag-NP-treated wheat grains indicated that Ag NPs indeed altered the nutrient contents in the edible portion. In the amino acid profile, the presence of Ag NPs significantly decreased the contents of arginine and histidine by 13.0 and 11.8%, respectively. In summary, the effects of metal-based NPs on the edible portion of crops should be taken into account in the evaluation of nanotoxicity to terrestrial plants. Moreover, investigation of the potential impacts of NP caused nutrient alterations on human health could further our understandings on NP-induced phytotoxicity. PMID- 29451786 TI - The Catalytic Reaction of Nitroxides with Peroxyl Radicals and Its Relevance to Their Cytoprotective Properties. AB - Sterically-hindered nitroxides such as 2,2,6,6-tetramethylpiperidin- N-oxyl (TEMPO) have long been ascribed antioxidant activity that is thought to underlie their chemopreventive and anti-aging properties. However, the most commonly invoked reactions in this context-combination with an alkyl radical to give a redox inactive alkoxyamine or catalysis of superoxide dismutation-are unlikely to be relevant under (most) physiological conditions. Herein, we characterize the kinetics and mechanisms of the reactions of TEMPO, as well as an N-arylnitroxide and an N, N-diarylnitroxide, with alkylperoxyl radicals, the propagating species in lipid peroxidation. In each of aqueous solution and lipid bilayers, they are found to be significantly more reactive than Vitamin E, Nature's premier radical trapping antioxidant (RTA). Inhibited autoxidations of THF in aqueous buffers reveal that nitroxides reduce peroxyl radicals by electron transfer with rate constants ( k ~ 106 to >107 M-1 s-1) that correlate with the standard potentials of the nitroxides ( E degrees ~ 0.75-0.95 V vs NHE) and that this activity is catalytic in nitroxide. Regeneration of the nitroxide occurs by a two-step process involving hydride transfer from the substrate to the nitroxide-derived oxoammonium ion followed by H-atom transfer from the resultant hydroxylamine to a peroxyl radical. This reactivity extends from aqueous solution to phosphatidylcholine liposomes, where added NADPH can be used as a hydride donor to promote nitroxide recycling, as well as to cell culture, where the nitroxides are shown to be potent inhibitors of lipid peroxidation-associated cell death (ferroptosis). These insights have enabled the identification of the most potent nitroxide RTA and anti-ferroptotic agent yet described: phenoxazine- N-oxyl. PMID- 29451787 TI - Effect of Methyl Substitution on the N-H...O Interaction in Complexes of Pyrrole with Water, Methanol, and Dimethyl Ether: Matrix Isolation Infrared Spectroscopy and ab Initio Computational Studies. AB - Hydrogen-bonded interactions of pyrrole with water and methanol have been studied using matrix isolation infrared spectroscopy and compared with the calculation performed on dimethyl ether. Computations carried out at MP2/aug-cc-pVDZ level of theory yielded two minima for the pyrrole-water and pyrrole-methanol complexes. The global and local minima correspond to the N-H...O and O-H...pi complexes, respectively, where the N-H group of pyrrole interacts with oxygen of water/methanol and O-H of water and methanol interacts with the pi cloud of pyrrole. Computations performed on the pyrrole-dimethyl ether gave only N-H...O type complex. From the experimental vibrational wavenumber shifts in the N-H stretching and N-H bending modes of pyrrole, as well as in the O-H stretching modes of water and methanol, the 1:1 N-H...O complexes were discerned. The strength of the N-H...O hydrogen bond and the corresponding shift in the N-H stretching vibrational wavenumbers increases in the order pyrrole-water < pyrrole methanol < pyrrole-dimethyl ether, where a proton is successively replaced by a methyl group. Apart from the 1:1 complexes, higher clusters of 2:1 and 1:2 pyrrole-water and pyrrole-methanol complexes were also generated in N2 matrix. Atoms in molecules and natural bond orbital analyses were carried out at the MP2/aug-cc-pVDZ level to understand the nature of interaction in the 1:1 pyrrole water, pyrrole-methanol and pyrrole-dimethyl ether complexes. PMID- 29451788 TI - Systematic Evaluation of the Use of Human Plasma and Serum for Mass-Spectrometry Based Shotgun Proteomics. AB - Over the last two decades, EDTA-plasma has been used as the preferred sample matrix for human blood proteomic profiling. Serum has also been employed widely. Only a few studies have assessed the difference and relevance of the proteome profiles obtained from plasma samples, such as EDTA-plasma or lithium-heparin plasma, and serum. A more complete evaluation of the use of EDTA-plasma, heparin plasma, and serum would greatly expand the comprehensiveness of shotgun proteomics of blood samples. In this study, we evaluated the use of heparin plasma with respect to EDTA-plasma and serum to profile blood proteomes using a scalable automated proteomic pipeline (ASAP2). The use of plasma and serum for mass-spectrometry-based shotgun proteomics was first tested with commercial pooled samples. The proteome coverage consistency and the quantitative performance were compared. Furthermore, protein measurements in EDTA-plasma and heparin-plasma samples were comparatively studied using matched sample pairs from 20 individuals from the Australian Imaging, Biomarkers and Lifestyle (AIBL) Study. We identified 442 proteins in common between EDTA-plasma and heparin plasma samples. Overall agreement of the relative protein quantification between the sample pairs demonstrated that shotgun proteomics using workflows such as the ASAP2 is suitable in analyzing heparin-plasma and that such sample type may be considered in large-scale clinical research studies. Moreover, the partial proteome coverage overlaps (e.g., ~70%) showed that measures from heparin-plasma could be complementary to those obtained from EDTA-plasma.

AB - Many technologically relevant semiconductors contain toxic, heavily regulated (Cd, Pb, As), or relatively scarce (Li, In) elements and often require high manufacturing costs. We report a facile, general, low-temperature, and size tunable (4-28 nm) solution phase synthesis of ternary APnE2 semiconductors based on Earth-abundant and biocompatible elements (A = Na, Pn = Bi, E = S or Se). The observed experimental band gaps (1.20-1.45 eV) fall within the ideal range for solar cells. Computational investigation of the lowest energy superstructures that result from "coloring", caused by mixed cation sites present in their rock salt lattice, agrees with other better-known members of this family of materials. Our synthesis unlocks a new class of low cost and environmentally friendly ternary semiconductors that show properties of interest for applications in energy conversion.

AB - A convenient synthetic route toward new copper(II) chlorate complexes with potential use in modern advanced ignition or initiation systems is described. Obtained compounds were not only accurately characterized (XRD, IR, UV/Vis EA and DTA) but also investigated for their energetic character (sensitivities, initiation capability and laser ignition). The copper 4-aminotriazolyl chlorate complex showed excellent initiation of PETN, while also being thermally stable and safe to handle. Solid-state UV-Vis measurements were performed to get a possible insight toward the laser initiation mechanism. In contrast to expectations, the presented copper(II) chlorate energetic coordination compounds show manageable sensitivities that can be tamed or boosted by the appropriate choice of nitrogen-rich ligands.

AB - The gas-phase laser-induced photoluminescence of cationic mononuclear gadolinium and lutetium complexes involving two 9-oxophenalen-1-one ligands is reported. Performing measurements at a temperature of 83 K enables us to resolve vibronic transitions. Via comparison to Franck-Condon computations, the main vibrational contributions to the ligand-centered phosphorescence are determined to involve rocking, wagging, and stretching of the 9-oxophenalen-1-one-lanthanoid coordination in the low-energy range, intraligand bending, and stretching in the medium- to high-energy range, rocking of the carbonyl and methine groups, and C-H stretching beyond. Whereas Franck-Condon calculations based on density-functional harmonic frequency computations reproduce the main features of the vibrationally resolved emission spectra, the absolute transition energies as determined by density functional theory are off by several thousand wavenumbers. This discrepancy is found to remain at higher computational levels. The relative energy of the Gd(III) and Lu(III) emission bands is only reproduced at the coupled-cluster singles and doubles level and beyond.

AB - When an excess electron is added into the pi* orbital of ethene, the resulting anion decays by electron autodetachment; that is, it represents an electronic state referred to as a temporary anion or resonance state. Here, the influence of a cluster environment on the energy and lifetime of this state is investigated. The clusters considered are ethene...CH4, ethene...C2H6, and ethene...H2O. Most of these clusters are systematically constructed so that the solvent interacts with the pi system in a specific way, and are thus by construction not minima with respect to all intermolecular degrees of freedom. However, for water, in addition, a minimal energy structure is examined. Systematic variation of the solvent and solvation geometry allows us to identify trends regarding effects due to polarizability, excluded volume, and polarity of the solvent molecules. The resonance parameters of ethene and all temporary cluster anions are computed with the symmetry-adapted cluster-configuration interaction electronic structure method in combination with a complex absorbing potential. This method is well established for small to intermediate sized molecules. In addition to the study of the solvation effects themselves, the question of how many basis functions are needed on the closed-shell solvating unit is examined.

PMID- 29451795 TI - Physisorption of H2 on Fullerenes and the Solvation of C60 by Hydrogen Clusters at Finite Temperature: A Theoretical Assessment. AB - The interaction between hydrogen and carbonaceous nanostructures is of fundamental interest in various areas of physical chemistry. In this contribution we have revisited the physisorption of hydrogen molecules and H2 clusters on fullerenes, following a first-principles approach in which the interaction is quantitatively evaluated for the C20 system using high-level electronic structure methods. Relative to coupled cluster data at the level of single, double, and perturbative triple excitations taken as a benchmark, the results for rotationally averaged physisorbed H2 show a good performance of MP2 variants and symmetry-adapted perturbation theory, but significant deviations and basis set convergence issues are found for dispersion-corrected density functional theory. These electronic structure data are fitted to produce effective coarse-grained potentials for use in larger systems such as C60-H2. Using path-integral molecular dynamics, the potentials are also applied to parahydrogen clusters solvated around fullerenes, across the regime where the first solvation shell becomes complete and as a function of increasing temperature. For C60 our findings indicate a sensible dependence of the critical solvation size on the underlying potential. As the temperature is increased, a competition is found between the surface and radial expansions of the solvation shell, with one molecule popping away at intermediate temperatures but getting reinserted at even higher temperatures.

AB - Curcumin is a polyphenol that exhibits several biological activities, but its low aqueous solubility results in low bioavailability. To improve curcumin bioavailability, this study has focused on developing a polyelectrolyte complexation method to form layer-by-layer assembled nanoparticles, for curcumin delivery, with positively charged chitosan (CS) and negatively charged acylated cruciferin (ACRU), a rapeseed globulin. Nanoparticles (NPs) were prepared from ACRU and CS (2:1) at pH 5.7. Three samples with weight of 5%, 10%, and 15% of curcumin, respectively, in ACRU/CS carrier were prepared. To verify the stability of the NPs, encapsulation efficiency and size of the 5% Cur-ACRU/CS NPs were determined at intervals of 5 days in a one month period. Fourier transform infrared spectroscopy (FTIR), X-ray diffraction, and differential scanning calorimetry confirmed the electrostatic interaction and hydrogen bond formation between the carrier and core. The result showed that hollow ACRU/CS nanocapsules (ACRU/CS NPs) and curcumin-loaded ACRU/CS nanoparticles (Cur-ACRU/CS NPs) were homogenized spherical with average sizes of 200-450 nm and zeta potential of +15 mV. Encapsulation and loading efficiencies were 72% and 5.4%, respectively. In vitro release study using simulated gastro (SGF) and intestinal fluids (SIF) showed controlled release of curcumin in 6 h of exposure. Additionally, the Cur ACRU/CS NPs are nontoxic to cultured Caco-2 cells, and the permeability assay indicated that Cur-ACRU/CS NPs had improved permeability efficiency of free curcumin through the Caco-2 cell monolayer. The findings suggest that ACRU/CS NPs can be used for encapsulation and delivery of curcumin in functional foods. PMID- 29451797 TI - Unimolecular Fragmentation of Deprotonated Diproline [Pro2-H]- Studied by Chemical Dynamics Simulations and IRMPD Spectroscopy. AB - Dissociation chemistry of the diproline anion [Pro2-H]- is studied using chemical dynamics simulations coupled with quantum-chemical calculations and RRKM analysis. Pro2- is chosen due to its reduced size and the small number of sites where deprotonation can take place. The mechanisms leading to the two dominant collision-induced dissociation (CID) product ions are elucidated. Trajectories from a variety of isomers of [Pro2-H]- were followed in order to sample a larger range of possible reactivity. While different mechanisms yielding y1- product ions are proposed, there is only one mechanism yielding the b2- ion. This mechanism leads to formation of a b2- fragment with a diketopiperazine structure. The sole formation of a diketopiperazine b2 sequence ion is experimentally confirmed by infrared ion spectroscopy of the fragment anion. Furthermore, collisional and internal energy activation simulations are used in parallel to identify the different dynamical aspects of the observed reactivity.

AB - This works deals with the identification of preferential site-specific activation at a model Pt surface during a multiproduct reaction. The (110)-type steps of a Pt(332) surface were selectively marked by attaching isotope-labeled 13CO molecules to them, and ethanol oxidation was probed by in situ Foureir transfrom infrared spectroscopy in order to precisely determine the specific sites at which CO2, acetic acid, and acetaldehyde were preferentially formed. The (110) steps were active for splitting the C-C bond, but unexpectedly, we provide evidence that the pathway of CO2 formation was preferentially activated at (111) terraces, rather than at (110) steps. Acetaldehyde was formed at (111) terraces at potentials comparable to those for CO2 formation also at (111) terraces, while the acetic acid formation pathway became active only when the (110) steps were released by the oxidation of adsorbed 13CO, at potentials higher than for the formation of CO2 at (111) terraces of the stepped surface. PMID- 29451799 TI - Three-Dimensional Integrated X-ray Diffraction Imaging of a Native Strain in Multi-Layered WSe2. AB - Emerging two-dimensional (2-D) materials such as transition-metal dichalcogenides show great promise as viable alternatives for semiconductor and optoelectronic devices that progress beyond silicon. Performance variability, reliability, and stochasticity in the measured transport properties represent some of the major challenges in such devices. Native strain arising from interfacial effects due to the presence of a substrate is believed to be a major contributing factor. A full three-dimensional (3-D) mapping of such native nanoscopic strain over micron length scales is highly desirable for gaining a fundamental understanding of interfacial effects but has largely remained elusive. Here, we employ coherent X ray diffraction imaging to directly image and visualize in 3-D the native strain along the (002) direction in a typical multilayered (~100-350 layers) 2-D dichalcogenide material (WSe2) on silicon substrate. We observe significant localized strains of ~0.2% along the out-of-plane direction. Experimentally informed continuum models built from X-ray reconstructions trace the origin of these strains to localized nonuniform contact with the substrate (accentuated by nanometer scale asperities, i.e., surface roughness or contaminants); the mechanically exfoliated stresses and strains are localized to the contact region with the maximum strain near surface asperities being more or less independent of the number of layers. Machine-learned multimillion atomistic models show that the strain effects gain in prominence as we approach a few- to single-monolayer limit. First-principles calculations show a significant band gap shift of up to 125 meV per percent of strain. Finally, we measure the performance of multiple WSe2 transistors fabricated on the same flake; a significant variability in threshold voltage and the "off" current setting is observed among the various devices, which is attributed in part to substrate-induced localized strain. Our integrated approach has broad implications for the direct imaging and quantification of interfacial effects in devices based on layered materials or heterostructures.

AB - An unprecedented visible-light photoredox-catalyzed iminyl radical formation by N H cleavage with H2 release has been developed. Its application in the synthesis of various isoquinolines and related polyaromatics in high atom economy at ambient temperature by applying a photosensitizer, Acr+-Mes ClO4-, and a new cobalt catalyst, Co(dmgH)2(4-CONMe2Py)Cl is reported. Mechanistic investigations indicated that the generated iminyl radical initiates the cascade C-N/C-C bonds formation and the catalytic cycle occurs by a simultaneous oxidative as well as reductive quenching pathway.

AB - We develop and perform continuum mechanics simulations of carbon nanotube (CNT) deployment directed by a combination of surface topography and rarefied gas flow. We employ the discrete elastic rods method to model the deposition of CNT as a slender elastic rod that evolves in time under two external forces, namely, van der Waals (vdW) and aerodynamic drag. Our results confirm that this self-assembly process is analogous to a previously studied macroscopic system, the "elastic sewing machine", where an elastic rod deployed onto a moving substrate forms nonlinear patterns. In the case of CNTs, the complex patterns observed on the substrate, such as coils and serpentines, result from an intricate interplay between van der Waals attraction, rarefied aerodynamics, and elastic bending. We systematically sweep through the multidimensional parameter space to quantify the pattern morphology as a function of the relevant material, flow, and geometric parameters. Our findings are in good agreement with available experimental data. Scaling analysis involving the relevant forces helps rationalize our observations. PMID- 29451802 TI - Nanoscale Mapping and Spectroscopy of Nonradiative Hyperbolic Modes in Hexagonal Boron Nitride Nanostructures. AB - The inherent crystal anisotropy of hexagonal boron nitride (hBN) provides the ability to support hyperbolic phonon polaritons, that is, polaritons that can propagate with very large wave vectors within the material volume, thereby enabling optical confinement to exceedingly small dimensions. Indeed, previous research has shown that nanometer-scale truncated nanocone hBN cavities, with deep subdiffractional dimensions, support three-dimensionally confined optical modes in the mid-infrared. Because of optical selection rules, only a few of the many theoretically predicted modes have been observed experimentally via far field reflection and scattering-type scanning near-field optical microscopy (s SNOM). The photothermal induced resonance (PTIR) technique probes optical and vibrational resonances overcoming weak far-field emission by leveraging an atomic force microscope (AFM) probe to transduce local sample expansion caused by light absorption. Here we show that PTIR enables the direct observation of previously unobserved, dark hyperbolic modes of hBN nanostructures. Leveraging these optical modes and their wide range of angular and radial momenta could provide a new degree of control over the electromagnetic near-field concentration, polarization in nanophotonic applications. PMID- 29451803 TI - Fluoroethylene Carbonate Induces Ordered Electrolyte Interface on Silicon and Sapphire Surfaces as Revealed by Sum Frequency Generation Vibrational Spectroscopy and X-ray Reflectivity. AB - The cyclability of silicon anodes in lithium ion batteries (LIBs) is affected by the reduction of the electrolyte on the anode surface to produce a coating layer termed the solid electrolyte interphase (SEI). One of the key steps for a major improvement of LIBs is unraveling the SEI's structure-related diffusion properties as charge and discharge rates of LIBs are diffusion-limited. To this end, we have combined two surface sensitive techniques, sum frequency generation (SFG) vibrational spectroscopy, and X-ray reflectivity (XRR), to explore the first monolayer and to probe the first several layers of electrolyte, respectively, for solutions consisting of 1 M lithium perchlorate (LiClO4) salt dissolved in ethylene carbonate (EC) or fluoroethylene carbonate (FEC) and their mixtures (EC/FEC 7:3 and 1:1 wt %) on silicon and sapphire surfaces. Our results suggest that the addition of FEC to EC solution causes the first monolayer to rearrange itself more perpendicular to the anode surface, while subsequent layers are less affected and tend to maintain their, on average, surface-parallel arrangements. This fundamental understanding of the near-surface orientation of the electrolyte molecules can aid operational strategies for designing high performance LIBs.

AB - Volatile sulfur compounds (VSCs), particularly low molecular weight sulfhydryls like hydrogen sulfide (H2S) and methanethiol (MeSH), are often observed in wines with sulfurous off-aromas. Recent work has shown both H2S and MeSH can increase up to a few uM (> 40 ug/L) during anoxic storage, but the identity of the latent sources of these sulfhydryls is still disputed. This review critically evaluates the latent precursors and pathways likely to be responsible for the loss and formation of these sulfhydryls during wine storage based on the existing enology literature as well as studies from food chemistry, geochemistry, biochemistry, and synthetic chemistry. We propose that three precursor classes have sufficient concentration and metastability to serve as latent sulfhydryl precursors in wine: 1) transition metal-sulfhydryl complexes, particularly those formed following Cu(II) addition, which are released under anoxic conditions through an unknown mechanism; 2) asymmetric disulfides, polysulfanes, and (di)organopolysulfanes formed through transition-metal mediated oxidation (e.g., Cu(II)) of sulfhydryls or pesticide degradation, and released through sulfitolysis, metal-catalyzed thiol-disulfide exchange or related reactions; 3) S-alkylthioacetates, primarily formed during fermentation, and releasable hydrolytically. Some evidence also exists for S-amino acids serving as precursors. Based on these findings, we propose a "decision tree" approach to choosing appropriate strategies for managing wines with sulfurous off-aromas.

PMID- 29451807 TI - Coenzyme Q10: From bench to clinic in aging diseases, a translational review. AB - Coenzyme Q10 (CoQ10) is a ubiquitous molecule present in all eukaryotic organisms whose principal role in the cell is related to its participation in the electron transport chain in the inner mitochondrial membrane. CoQ10 plays a major role in the control of cell redox status, and both the amount and functionality of this molecule have been related to the regulation of reactive oxygen species generation. Numerous reports can be found discussing the implications of CoQ10 supplementation in human studies and clinical trials related to aging. However, few reviews have made an updating through the translational point of view to integrate both basic and clinical aspects. The aim of this paper is to review our current knowledge from CoQ10 implications at biochemical and physiological level, in order to unravel the molecular mechanisms involved in its application in clinical practice. Although the importance of CoQ10 has been mainly attributed to its role as an agent for energy transduction in mitochondria, new functions for CoQ10 have been described in the recent past years, including anti-inflammatory effects, gene expression regulation and lipid bilayer membranes stabilization, which explain its involvement in aging and age-related diseases such as cardiovascular diseases, renal failure and neurodegenerative diseases.

AB - Nuclear magnetic resonance (NMR) is a rapid, accurate and non-invasive technology and widely used to detect the quality of food, particularly to fruits and vegetables, meat and aquatic products. This review is a survey of recent developments in experimental results for the quality of food on various NMR technologies in processing and storage over the past decade. Following a discussion of the quality discrimination and classification of food, analysis of food compositions and detection of physical, chemical, structural and microbiological properties of food are outlined. Owing to high cost, low detection limit and sensitivity, the professional knowledge involved and the safety issues related to the maintenance of the magnetic field, so far the practical applications are limited to detect small range of food. In order to promote applications for a broader range of foods further research and development efforts are needed to overcome the limitations of NMR in the detection process. The needs and opportunities for future research and developments are outlined. PMID- 29451811 TI - Role of Tendoscopy in Treating Stage II Posterior Tibial Tendon Dysfunction. AB - BACKGROUND: Stage II tibialis posterior tendon dysfunction (PTTD) resistant to conservative therapies is usually treated with invasive surgery. Posterior tibial tendoscopy is a novel technique being used in the assessment and treatment of posterior tibial pathology. The aims of this study were (1) to clarify the role of posterior tibial tendon tendoscopy in treating stage II PTTD, (2) to arthroscopically classify spring ligament lesions, and (3) to compare the arthroscopic assessment of spring ligament lesions with magnetic resonance imaging (MRI) and ultrasonographic (US) data. METHODS: We reviewed prospectively collected data on 16 patients affected by stage II PTTD and treated by tendoscopy. We report the reoperation rate and functional outcomes evaluated by comparing pre- and postoperative visual analogic scale for pain (VAS-pain) and the Short-Form Health Survey (SF-36; with its physical [PCS] and mental [MCS] components). Postoperative satisfaction was assessed using a VAS-satisfaction scale. One patient was lost to follow-up. Spring ligament lesions were arthroscopically classified in 3 stages. Discrepancies between preoperative imaging and intraoperative findings were evaluated. RESULTS: At a mean of 25.6 months' follow-up, VAS-pain ( P < .001), SF-36 PCS ( P = .039), and SF-36 MCS ( P < .001) significantly improved. The mean VAS-satisfaction score was 75.3/100. Patients were relieved from symptoms in 80% of cases, while 3 patients required further surgery. MRI and US were in agreement with intraoperative data in 92% and 67%, respectively, for the tendon assessment and in 78% and 42%, respectively, for the spring ligament. CONCLUSIONS: Tendoscopy may be considered a valid therapeutic tool in the treatment of stage II PTTD resistant to conservative treatment. It provided objective and subjective encouraging results that could allow continued conservative therapy while avoiding more invasive surgery in most cases. MRI and US were proven more useful in detecting PT lesions than spring ligament tears. Further studies on PT could use this tendoscopic classification to standardize its description.

AB - Most alkaloids are produced by plants as a defense mechanism against herbivores. Since alkaloids are known to possess pharmacological effects, this study sought to investigate the in vitro modulatory effect of alkaloid obtained from two commonly consumed vegetables in southern Nigeria, Lasianthera africana (editan) and Gongronema latifolium (utazi), on some enzyme activities relevant to neurodegeneration. Effects of the alkaloids on cholinesterases (acetylcholinesterase [AChE] and butyrylcholinesterase [BChE]) and monoamine oxidase (MAO) activities were determined in vitro. In addition, Fe2+ chelating ability as well as radical-scavenging abilities were determined. Alkaloid profile was also determined using gas chromatography coupled with flame ionization detector (GC-FID). The results revealed that the alkaloids inhibited AChE, BChE, and MAO activities in a concentration-dependent manner, such that the alkaloid from G. latifolium showed higher enzyme inhibition (AChE [IC50 = 87.39 ug/ml], BChE [IC50 = 118.65 ug/ml], and MAO [IC50 = 61.37 ug/ml]) than L. africana (AChE = 115.60 ug/ml; BChE = 169.48 ug/ml; MAO = 73.72 ug/ml). In addition, GC-FID analysis revealed abundance of choline in both extracts. Gongronema latifolium and Lasianthera africana alkaloid extracts inhibit enzymes (acetylcholinesterase, butyrylcholinesterase, and monoamine oxidase) implicated in neurodegenerative diseases. Hence, these vegetables could offer dietary supplement in the management of neurodegenerative diseases.

AB - OBJECTIVE: To describe the variation in asthma quality and costs among children with different Medicaid insurance plans. METHODS: We used 2013 data from the Center for Health Information and Research, which houses a database that includes individuals who have Medicaid insurance in Arizona. We analyzed children ages 2 17 years-old who lived in Maricopa County, Arizona. Asthma medication ratio (AMR, a measure of appropriate asthma medication use), outpatient follow-up within 2 weeks after asthma-related hospitalization (a measure of continuity of care), asthma-related hospitalizations, and all emergency department (ED) visits were the primary quality metrics. Direct costs were reported in 2013 $US dollars. We used one-way analysis of variance to compare the health plans for AMR and per member cost (total, ER, and hospital), and the chi-squared test for the outpatient follow-up measure. We used coefficient of variation to identify variation of each measure across all individuals in the study. RESULTS: In 2013, 90,652 children in Maricopa County were identified as having asthma. The average patient-weighted AMR for children with persistent asthma was 0.35, well short of the goal of >=0.70, and only 36% of hospitalized asthma patients had outpatient follow-up within 2 weeks of hospitalization. AMR, total costs, and ED costs varied significantly (p <.0001) when comparing health plans while hospital costs and outpatient follow-up showed no significant variation. CONCLUSIONS: Targeting appropriate medication use for asthma may help reduce variation, improve outcomes, and increase healthcare value for children with asthma and Medicaid insurance in the US. PMID- 29451815 TI - Gender differences in substance use treatment and substance use among adults on probation. AB - BACKGROUND: Although many formal and informal substance use treatment programs were originally designed for men, no studies have investigated how gender affects the use of substance use treatment modalities, and how gender differences in treatment utilization impact substance use in the unique probation context. OBJECTIVE: To describe gender differences in use and effectiveness of substance use treatment modalities (formal and informal) among probationers. METHODS: Longitudinal data were obtained from 335 individuals (93 women) who participated in the Motivational Assessment Program to Initiate Treatment (MAPIT) study. Timeline follow-back measures were used to quantify daily substance use and treatment modality (formal treatment included inpatient and outpatient treatment; informal treatment included self-help, religious, and all other group meetings). Multivariate generalized estimating equations were used to examine relationships between gender, treatment, and substance use. RESULTS: Gender was not associated with alcohol use. Use of formal treatment programs reduced the odds of alcohol use by 15%. The probability of alcohol use was the lowest (8%) for men who participated in formal treatment. For men using informal treatment programs, the probability of alcohol use was 11%. The probability of alcohol use for women was similar regardless of the type of treatment utilization (15-16%). No differences in illicit drug use by gender or type of treatment were detected. CONCLUSION: This research found limited evidence of a relationship between gender, substance use treatment modality, and alcohol use. These findings have clinical significance in that both formal and informal treatment approaches are similarly effective across both men and women. PMID- 29451816 TI - Effects of teriparatide on morphology of aortic calcification in aged hyperlipidemic mice. AB - Calcific aortic vasculopathy correlates with bone loss in osteoporosis in an age independent manner. Prior work suggests that teriparatide, the bone anabolic treatment for postmenopausal osteoporosis, may inhibit the onset of aortic calcification. Whether teriparatide affects the progression of preexisting aortic calcification, widespread among this patient population, is unknown. Female apolipoprotein E-deficient mice were aged for over 1 yr to induce aortic calcification, treated for 4.5 wk with daily injections of control vehicle (PBS), 40 ug/kg teriparatide (PTH40), or 400 ug/kg teriparatide (PTH400), and assayed for aortic calcification by microcomputed tomography (microCT) before and after treatment. In a followup cohort, aged female apolipoprotein E-deficient mice were treated with PBS or PTH400 and assayed for aortic calcification by serial microCT and micropositron emission tomography. In both cohorts, aortic calcification detected by microCT progressed similarly in all groups. Mean aortic 18F-NaF incorporation, detected by serial micropositron emission tomography, increased in the PBS-treated group (+14 +/- 5%). In contrast, 18F-NaF incorporation decreased in the PTH400-treated group (-33 +/- 20%, P = 0.03). Quantitative histochemical analysis by Alizarin red staining revealed a lower mineral surface area index in the PTH400-treated group compared with the PBS-treated group ( P = 0.04). Furthermore, Masson trichrome staining showed a significant increase in collagen deposition in the left ventricular myocardium of mice that received PTH400 [2.1 +/- 0.6% vs. control mice (0.5 +/- 0.1%), P = 0.02]. In summary, although teriparatide may not affect the calcium mineral content of aortic calcification, it reduces 18F-NaF uptake in calcified lesions, suggesting the possibility that it may reduce mineral surface area with potential impact on plaque stability. NEW & NOTEWORTHY Parathyroid hormone regulates bone mineralization and may also affect vascular calcification, which is an important issue, given that its active fragment, teriparatide, is widely used for the treatment of osteoporosis. To determine whether teriparatide alters vascular calcification, we imaged aortic calcification in mice treated with teriparatide and control mice. Although teriparatide did not affect the calcium content of cardiovascular deposits, it reduced their fluoride tracer uptake.

We have previously shown that a heart-specific myosin light chain phosphatase small subunit (hHS-M21) increases the Ca2+ sensitivity of muscle contraction. The aim of the present study was to investigate the function of hHS-M21 in vivo and the causative role of abnormal Ca2+ sensitivity in cardiomyopathy. We generated transgenic mice with cardiac-specific overexpression of hHS-M21. We confirmed that hHS-M21 increased the Ca2+ sensitivity of cardiac muscle contraction in vivo, which was not followed by an increased phosphorylation of myosin light chain 2 isoforms. hHS-M21 transgenic mice developed severe systolic dysfunction with myocardial fibrosis and degeneration of cardiomyocytes in association with sinus bradycardia and atrioventricular conduction defect. The contractile dysfunction and cardiac fibrosis were improved by treatment with the Rho kinase inhibitor fasudil. Our findings suggested that the overexpression of hHS-M21 results in cardiac dysfunction and conduction disturbance via non-myosin light chain 2 phosphorylation-dependent regulation. NEW & NOTEWORTHY The present study is the first to develop mice with transgenic overexpression of a heart-specific myosin light chain phosphatase small subunit (hHS-M21) and to examine the effects of hHS-M21 on cardiac function. Elevation of hHS-M21 induced heart failure with myocardial fibrosis and degeneration of cardiomyocytes accompanied by supraventricular arrhythmias.

AB - While it is known that chronic stress and clinical depression are powerful predictors of poor cardiovascular outcomes, recent clinical evidence has identified correlations between the development of metabolic disease and depressive symptoms, creating a combined condition of severely elevated cardiovascular disease risk. In this study, we used the obese Zucker rat (OZRs) and the unpredictable chronic mild stress (UCMS) model to determine the impact of preexisting metabolic disease on the relationship between chronic stress/depressive symptoms and vascular function. Additionally, we determined the impact of metabolic syndrome on sex-based protection from chronic stress/depressive effects on vascular function in female lean Zucker rats (LZRs). In general, vasodilator reactivity was attenuated under control conditions in OZRs compared with LZRs. Although still impaired, conduit arterial and resistance arteriolar dilator reactivity under control conditions in female OZRs was superior to that in male or ovariectomized (OVX) female OZRs, largely because of better maintenance of vascular nitric oxide and prostacyclin levels. However, imposition of metabolic syndrome in combination with UCMS in OZRs further impaired dilator reactivity in both vessel subtypes to a similarly severe extent and abolished any protective effect in female rats compared with male or OVX female rats. The loss of vascular protection in female OZRs with UCMS was reflected in vasodilator metabolite levels, which closely matched those in male and OVX female OZRs subjected to UCMS. These results suggest that presentation of metabolic disease in combination with depressive symptoms can overwhelm the vasoprotection identified in female rats and, thereby, may reflect a severe impairment to normal endothelial function. NEW & NOTEWORTHY This study addresses the protection from chronic stress- and depression-induced vascular dysfunction identified in female compared with male or ovariectomized female rats. We determined the impact of preexisting metabolic disease, a frequent comorbidity of clinical depression in humans, on that vascular protection. With preexisting metabolic syndrome, female rats lost all protection from chronic stress/depressive symptoms and became phenotypically similar to male and ovariectomized female rats, with comparably poor vasoactive dilator metabolite profiles. PMID- 29451820 TI - The HCM-linked W792R mutation in cardiac myosin-binding protein C reduces C6 FnIII domain stability. AB - Cardiac myosin-binding protein C (cMyBP-C) is a functional sarcomeric protein that regulates contractility in response to contractile demand, and many mutations in cMyBP-C lead to hypertrophic cardiomyopathy (HCM). To gain insight into the effects of disease-causing cMyBP-C missense mutations on contractile function, we expressed the pathogenic W792R mutation (substitution of a highly conserved tryptophan residue by an arginine residue at position 792) in mouse cardiomyocytes lacking endogenous cMyBP-C and studied the functional effects using three-dimensional engineered cardiac tissue constructs (mECTs). Based on complete conservation of tryptophan at this location in fibronectin type II (FnIII) domains, we hypothesized that the W792R mutation affects folding of the C6 FnIII domain, destabilizing the mutant protein. Adenoviral transduction of wild-type (WT) and W792R cDNA achieved equivalent mRNA transcript abundance, but not equivalent protein levels, with W792R compared with WT controls. mECTs expressing W792R demonstrated abnormal contractile kinetics compared with WT mECTs that were nearly identical to cMyBP-C-deficient mECTs. We studied whether common pathways of protein degradation were responsible for the rapid degradation of W792R cMyBP-C. Inhibition of both ubiquitin-proteasome and lysosomal degradation pathways failed to increase full-length mutant protein abundance to WT equivalence, suggesting rapid cytosolic degradation. Bacterial expression of WT and W792R protein fragments demonstrated decreased mutant stability with altered thermal denaturation and increased susceptibility to trypsin digestion. These data suggest that the W792R mutation destabilizes the C6 FnIII domain of cMyBP-C, resulting in decreased full-length protein expression. This study highlights the vulnerability of FnIII-like domains to mutations that alter domain stability and further indicates that missense mutations in cMyBP-C can cause disease through a mechanism of haploinsufficiency. NEW & NOTEWORTHY This study is one of the first to describe a disease mechanism for a missense mutation in cardiac myosin-binding protein C linked to hypertrophic cardiomyopathy. The mutation decreases stability of the fibronectin type III domain and results in substantially reduced mutant protein expression dissonant to transcript abundance.

AB - BACKGROUND: Donor human milk is considered the next best nutrition following mother's own milk to prevent neonatal infection and necrotizing enterocolitis in preterm infants who are admitted at neonatal intensive care unit. However, donor milk biofunctionalities after preparative processes have rarely been documented. OBJECTIVE: To evaluate biofunctionalities preserved in donor milk after preparative processes by cell-based assays. MATERIALS AND METHODS: Ten pools of donor milk were produced from 40 independent specimens. After preparative processes, including bacterial elimination methods (holder pasteurization and cold-sterilization microfiltration) and storage conditions (-20 degrees C freezing storage and lyophilization) with varied duration of storage (0, 3, and 6, months), donor milk biofunctionalities were examined by fetal intestinal cell growth and antimicrobial assays. RESULTS: At baseline, raw donor milk exhibited 193.1% +/- 12.3% of fetal intestinal cell growth and 42.4% +/- 11.8% of antimicrobial activities against Escherichia coli. After bacteria eliminating processes, growth promoting activity was better preserved in pasteurized donor milk than microfiltrated donor milk (169.5% +/- 14.3% versus 146.0% +/- 11.8%, respectively; p < 0.005), whereas antimicrobial activity showed no difference between groups (38.3% +/- 14.1% versus 53.7% +/- 17.3%, respectively; p = 0.499). The pasteurized donor milk was further examined for the effects of storage conditions at 3 and 6 months. Freezing storage, but not lyophilization, could preserve higher growth-promoting activity during 6 months of storage (163.0% +/- 9.4% versus 72.8% +/- 6.2%, respectively; p < 0.005). Nonetheless, antimicrobial activity was lost at 6 months, regardless of the storage methods. CONCLUSIONS: This study revealed that fetal intestinal cell growth and antimicrobial assays could be applied to measure donor milk biofunctionalities and support the utilization of donor milk within 3 months after preparative processes. PMID- 29451817 TI - Impact of pulse pressure on cerebrovascular events leading to age-related cognitive decline. AB - Aging is a modern concept: human life expectancy has more than doubled in less than 150 yr in Western countries. Longer life span, however, reveals age-related diseases, including cerebrovascular diseases. The vascular system is a prime target of aging: the "wear and tear" of large elastic arteries exposed to a lifelong pulsatile pressure causes arterial stiffening by fragmentation of elastin fibers and replacement by stiffer collagen. This arterial stiffening increases in return the amplitude of the pulse pressure (PP), its wave penetrating deeper into the microcirculation of low-resistance, high-flow organs such as the brain. Several studies have associated peripheral arterial stiffness responsible for the sustained increase in PP, with brain microvascular diseases such as cerebral small vessel disease, cortical gray matter thinning, white matter atrophy, and cognitive dysfunction in older individuals and prematurely in hypertensive and diabetic patients. The rarefaction of white matter is also associated with middle cerebral artery pulsatility that is strongly dependent on PP and artery stiffness. PP and brain damage are likely associated, but the sequence of mechanistic events has not been established. Elevated PP promotes endothelial dysfunction that may slowly develop in parallel with the accumulation of proinflammatory senescent cells and oxidative stress, generating cerebrovascular damage and remodeling, as well as brain structural changes. Here, we review data suggesting that age-related increased peripheral artery stiffness may promote the penetration of a high PP to cerebral microvessels, likely causing functional, structural, metabolic, and hemodynamic alterations that could ultimately promote neuronal dysfunction and cognitive decline.

PMID- 29451821 TI - Protection from vascular dysfunction in female rats with chronic stress and depressive symptoms. AB - The increasing prevalence and severity of clinical depression are strongly correlated with vascular disease risk, creating a comorbid condition with poor outcomes but demonstrating a sexual disparity whereby female subjects are at lower risk than male subjects for subsequent cardiovascular events. To determine the potential mechanisms responsible for this protection against stress/depression-induced vasculopathy in female subjects, we exposed male, intact female, and ovariectomized (OVX) female lean Zucker rats to the unpredictable chronic mild stress (UCMS) model for 8 wk and determined depressive symptom severity, vascular reactivity in ex vivo aortic rings and middle cerebral arteries (MCA), and the profile of major metabolites regulating vascular tone. While all groups exhibited severe depressive behaviors from UCMS, severity was significantly greater in female rats than male or OVX female rats. In all groups, endothelium-dependent dilation was depressed in aortic rings and MCAs, although myogenic activation and vascular (MCA) stiffness were not impacted. Higher resolution results from pharmacological and biochemical assays suggested that vasoactive metabolite profiles were better maintained in female rats with normal gonadal sex steroids than male or OVX female rats, despite increased depressive symptom severity (i.e., higher nitric oxide and prostacyclin and lower H2O2 and thromboxane A2 levels). These results suggest that female rats exhibit more severe depressive behaviors with UCMS but are partially protected from the vasculopathy that afflicts male rats and female rats lacking normal sex hormone profiles. Determining how female sex hormones afford partial vascular protection from chronic stress and depression is a necessary step for addressing the burden of these conditions on cardiovascular health. NEW & NOTEWORTHY This study used a translationally relevant model for chronic stress and elevated depressive symptoms to determine how these factors impact conduit and resistance arteriolar function in otherwise healthy rats. While chronic stress leads to an impaired vascular reactivity associated with elevated oxidant stress, inflammation, and reduced metabolite levels, we demonstrated partial protection from vascular dysfunction in female rats with normal sex hormone profiles compared with male or ovariectomized female rats.

AB - There continues to be a need in the field of psychology for measures that quantify qualitative data in dynamically rich and clinically meaningful ways. The Social Cognition and Object Relations Scale-Global Rating Method (SCORS-G; Westen, 1995) is a clinician-rated measure with a strong theoretical foundation that assesses sophisticated underlying constructs, specifically 8 dimensions of object relations (Stein & Slavin-Mulford, 2018 ). The SCORS-G has steadily increased in popularity and this special section of the Journal of Personality Assessment reflects this growing interest. In this introduction, we provide readers with a brief overview of the 5 articles in this special section and note ways in which they reflect and build on the existing SCORS-G empirical literature. Contextualizing these articles within the broader literature allows us to highlight how the measure is employed in clinical and research settings. Each of these 5 articles also highlights areas and opportunities for future research that would address gaps in the SCORS-G literature and strengthen the utility of the measure. We close by noting how each of studies can be seen as a model for future lines of research. PMID- 29451826 TI - Flexibility and Rigidity in Object Relational Functioning: Assessing Change in Suicidal Ideation and Global Psychiatric Functioning Using the SCORS-G. AB - The Social Cognition and Object Relations Scale-Global Rating Method (SCORS-G; Westen, 1995 ) has been widely used as an assessment measure of object relational functioning across a number of stimuli. This study used the SCORS-G to investigate associations between global impairments and rigidity in quality of object relations with changes in suicidal ideation and psychiatric functioning over time. Participant narratives describing actual interpersonal experiences were collected using the Relationship Anecdote Paradigm (Luborsky, 1998 ) from a sample of individuals diagnosed with complex psychopathology completing residential psychiatric treatment. We found that a greater range in affective quality and emotional investment in relationship scores at admission into treatment were significantly related to a reduction in suicidal ideation as well as improvements in global psychiatric functioning at 5-year follow-up. Thus, participants who acknowledged having both healthy as well as troubled relationships in their daily lives were less suicidal and less likely to experience disruptive psychiatric symptoms over time than those who described more restricted or uniform relational experiences on entering treatment. Implications for calculating range scores and using various narrative techniques when applying the SCORS-G method are discussed. PMID- 29451827 TI - Sending the Right Message: Wild Game and the West Africa Ebola Outbreak. AB - The unprecedented scale of the Ebola epidemic in West Africa in 2014-15 caught the world by surprise. Zaire Ebolavirus had not previously been documented in Guinea, Sierra Leone, or Liberia. However, since this strain of filovirus was first identified in 1976, scientists have been studying the disease and its origins. They have identified forest-dwelling animals that carry the virus, and some that die from it, but have yet to isolate how it is transmitted from animals to humans. During the height of the Ebola outbreak in West Africa, some public health messages addressed the link among Ebola, wild animals, and humans. This article analyzes 3 of those health messages and identifies information that is inconsistent with scientific research. Two additional examples illustrate more accurate public health messages. Until there is greater certainty about the nature of the transmission chain, future public health campaigns may be improved by timing, placement, images, and wording that provide the most accurate information to the most appropriate audience. PMID- 29451828 TI - The Effect of Omega-3 Fatty Acids, EPA, and/or DHA on Male Infertility: A Systematic Review and Meta-analysis. AB - The objective was to evaluate the effect of docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) on sperm parameters including total sperm concentration, sperm motility, sperm DHA, and seminal plasma DHA concentration in infertile men. The literature search was conducted in PubMed, Google Scholar, and Scopus from January 1, 1990 to December 20, 2017. The systematic review and meta analysis were based on randomized controlled trials in infertile men with DHA or EPA treatments, either alone or in combination with other micronutrients. Three studies met the inclusion criteria: 147 patients in the intervention group and 143 patients in the control group. The analysis showed that omega-3 treatments significantly increased the sperm motility (RR 5.82, 95% CI [2.91, 8.72], p <. 0001, I2 = 76%) and seminal DHA concentration (RR 1.61, 95% CI [0.15, 3.07], p =. 03, I2 = 98%). Compared with the controls, the interventions did not affect the sperm concentration (RR 0.31, 95% CI [-8.13, 8.76], p =. 94, I2 = 95%) or sperm DHA (RR 0.50, 95% CI [-4.17, 5.16], p =. 83, I2 = 99%). The observed heterogeneity may be due to administration period and dosage of omega-3 fatty acids across the studies. Funnel plot shows no evidence of publication bias. This meta-analysis indicates that supplementing infertile men with omega-3 fatty acids resulted in a significant improvement in sperm motility and concentration of DHA in seminal plasma. PMID- 29451829 TI - Survivor Notification of Post-Disaster Mental Health Services: An Integrative Review. AB - This integrative review identifies notification methods for psychiatric mental health services for adult survivors of natural disasters for articles published from 2011 through 2016. Databases searched included Scopus, Cochrane Library, CINAHL Plus, Ovid MEDLINE, and Ovid PsycINFO. The search was limited to English language. Initially, 273 titles/abstracts were reviewed, and 18 articles were retained for synthesis. Communication occurs through formal means of health care provider referrals and online programs (72%); informal supports are friends, family and clergy (28%). Mental health providers have significant impact on disaster recovery by developing plans for communication. PMID- 29451830 TI - Quality of Life and African American Women Who are Family Caregivers: A Literature Review with Implications for Psychiatric Mental Health Advanced Practice Registered Nurses. AB - PURPOSE: To identify factors affecting the quality of life (QOL) of African American women (AAW) family caregivers of individuals with kidney failure. METHODS: Ferrans' Conceptual Model of QOL provided the framework for this literature review. Included studies were (a) peer- reviewed, (b) published within the last ten years, (c) written in English, and (d) examined QOL of AAW family caregivers. Using CINAHL(c) and PubMed(c), we found 14 studies that described factors associated with these caregivers' QOL. SCOPE: Few studies document the QOL of AAW who are family caregivers, especially in the context of kidney failure. Psychiatric Mental Health Advanced Practice Registered Nurses need to learn about the factors influencing the QOL of these caregivers. RESULTS: No studies were found within the last ten years that explored the QOL of AAW family caregivers of individuals with kidney failure. Findings reflected the QOL of AAW family caregivers in the context of other chronic conditions. Various factors such as stress, insomnia, and employment were linked to an impaired QOL. Implications for practice, research and education for PMH-APRNs are suggested. CONCLUSION: PMH-APRNs are uniquely trained to address many factors that affect the QOL of these caregivers and may provide holistic care aimed at promoting satisfactory QOL for these caregivers. PMID- 29451831 TI - High-Dose Perinatal Folic-Acid Supplementation Alters Insulin Sensitivity in Sprague-Dawley Rats and Diminishes the Expression of Adiponectin. AB - The possible intake of folate in excess of the recommended upper levels is a matter of critical importance. This study was conducted to investigate the effects of prenatal and postnatal high folic acid supplementation (FAS) on glucose tolerance, insulin sensitivity, lipid metabolism, and expression of adiponectin in rats. The study included 20 female rats divided into two groups: control group and FAS group (receiving high folic acid supplemented diet). Both groups of female rats were mated and pregnancy confirmed. At parturition, the diet of 5 dams that were fed with control diet during gestation and their litters was changed to FAS diet and continued throughout lactation. Similarly, half of the dams that were previously fed with FAS diet during gestation and their litters were also changed to control diet. The remaining 5 dams in each group continued on their respective diets throughout lactation with their litters. Other dams remained on their respective diets throughout lactation. Food and water intake, body weight, lipid concentrations, insulin, and the expression of adiponectin were determined. Glucose tolerance and insulin sensitivity were also measured to evaluate glucose homeostasis. FAS significantly increased the postweaning food, water intake, triglyceride, and insulin levels but diminished insulin sensitivity in adult offspring. The expression of adiponectin in insulin sensitive tissues was also significantly decreased and these were consistent with insulin resistance of FAS offspring. High-dose FAS may promote insulin resistance and dyslipidemia and disrupt glucose metabolism possibly by depressing adiponectin expression. Although this is an animal model and the effects of the diets cannot be directly transposed to humans, this study provides indications of the possible adverse effects of FAS maternal diet on glucose metabolism in the offspring. PMID- 29451832 TI - Circulating progenitor cells and their interaction with platelets in patients with an acute coronary syndrome. AB - CD34+ cells expressing KDR (CD34+/KDR+) represent a small proportion of circulating progenitor cells that have the capacity to interact with platelets and to differentiate into mature endothelial cells, thus contributing to vascular homeostasis and regeneration as well as to re-endothelialization. We investigated the levels of CD34+ and CD34+/KDR+ progenitor cells as well as their interaction with platelets in acute coronary syndrome (ACS) patients before the initiation (baseline) of their treatment with a P2Y12 receptor antagonist, and at 5-days post-treatment (follow-up). Sixty-seven consecutive ACS patients and thirty healthy subjects (controls) participated in the study. On admission, all patients received 325 mg aspirin, followed by 100 mg/day and then were loaded either with 600 mg clopidogrel or 180 mg ticagrelor, followed by 75 mg/day (n = 36) or 90 mg * 2/day (n = 31), respectively. The levels of circulating CD34+ and CD34+/KDR+ progenitor cells, as well as their interaction with platelets, were determined by flow cytometry, before and after activation with ADP, in vitro. The circulating levels of CD34+ and CD34+/KDR+ cells in both patient groups at baseline were lower compared with controls while they were significantly increased at 5-days of follow-up in both groups, this increase being more pronounced in the ticagrelor group. The platelet/CD34+ (CD61+/CD34+) conjugates were higher at baseline and reduced at follow-up while the platelet/KDR+ (CD61+/KDR+) conjugates were lower at baseline and increased at follow-up, both changes being more pronounced in the ticagrelor group. ADP activation of control samples significantly increased the KDR expression by CD34+ cells and the CD61+/KDR+ conjugates, these parameters being unaffected in patients at baseline but increased at follow-up. Short-term dual antiplatelet therapy in ACS patients restores the low platelet/KDR+ conjugates and CD34+ cell levels and improves the low membrane expression levels of KDR in these cells, an effect being more pronounced in ticagrelor-treated patients. This may represent a pleiotropic effect of antiplatelet therapy towards vascular endothelial regeneration. PMID- 29451833 TI - Development and pilot testing of a text message vaccine reminder system for use during an influenza pandemic. AB - In an influenza pandemic, two vaccine doses administered 21 days apart may be needed for individuals of all ages to achieve seroprotection. Achieving dose series completion can be challenging even for routinely recommended vaccines. To prepare for a two-dose influenza pandemic vaccine campaign and promote dose series completion and correct dosing intervals, CDC and its partners developed a text message-based vaccine reminder system to remind persons who receive a first dose of pandemic influenza vaccine to receive the second dose. Taking advantage of the high prevalence of cell phones in the United States, the system sent second-dose text message reminders and hyperlinks to educational information. The system was pilot tested from November 2015 to April 2016 among graduate public health students enrolled at four United States universities. Universities were selected based on convenience, and each university used a different recruitment method. Among 59 volunteers who pilot tested the system and completed a survey, 57 (92%) felt the system would be helpful during a pandemic. Forty (68%) respondents felt the information included in the messages was informative. Volunteers recommended including actionable ways to stay healthy during a pandemic, though specific suggestions varied. With further development, text reminder systems could be used to promote adherence to a two-dose regimen in a future pandemic, although audience-specific messaging and other complementary systems will likely be needed. Public and private partners can adapt and implement this tool in conjunction with their routine patient information systems to improve dose-series completion and ensure optimal protection during an influenza pandemic. PMID- 29451834 TI - Influenza vaccination 2014-2015: Results of a survey conducted among general practitioners in Italy. AB - INTRODUCTION: The aim of the present study was to evaluate orientation, organizational procedures implemented and difficulties faced by general practitioners (GPs) during the 2014/15 seasonal influenza vaccination programme, as well as GPs' general attitude towards vaccinations. METHODS: An ad hoc online survey was developed and administered to general practitioners members of the Italian Federation of GPs (Federazione Italiana Medici di Medicina Generale - FIMMG). Overall, 10,000 survey invitations were sent. Data were analysed with R 3.3.2 software for analyses. Odds ratios (OR) were calculated in univariable and multivariable analyses. RESULTS: A sample of 1,245 GPs participated in the survey. Only slightly more than one third achieved a vaccination coverage comprised between 61% and 75%. In over half of the cases, the local health unit does not allow the GPs to choose the type of vaccine; 8.8% did not receive operational information at the beginning of the vaccination campaign and almost half did not receive feedback information at the end of the campaign. Almost three quarters reported that the vaccination uptake should increase. One tenth of GPs totally disagreed with the statement that vaccinating healthcare workers is crucial to prevent and control infections, and one fifth had not been vaccinated in the prior decade. DISCUSSION: The efforts made to vaccinate elderly individuals did not reach the expected results; still many GPs complained about lack of information by the relevant public health institutions and organizational difficulties. A stronger commitment of public health authorities would entail a higher vaccination uptake. PMID- 29451835 TI - Characteristics and Outcomes of Advanced Cancer Patients Who Received Palliative Care at a Public Hospital Compared with Those at a Comprehensive Cancer Center. AB - BACKGROUND: Patients with advanced cancer experience severe physical, psychosocial, and spiritual distress requiring palliative care (PC). There are limited literature regarding characteristics and outcomes of patients evaluated by PC services at public hospitals (PHs). Objective, Design, Setting/Subjects, and Measurements: To compare the outcomes of advanced cancer patients undergoing PC at a PH and those at a comprehensive cancer center (CCC). We reviewed 359 consecutive advanced cancer patients (PH, 180; CCC, 179) undergoing PC. Symptoms and outcomes at consultation and first follow-up visit were assessed. Summary statistics were used to describe patient characteristics and outcomes. RESULTS: The PH and CCC patients differed significantly according to race: 23% white, 39% black, and 36% Hispanic patients at the PH versus 66% white, 17% black, and 11% Hispanic patients at the CCC (p < 0.0001). Ninety-six (53%) patients at PH and 178 (99%) at the CCC had health insurance (p < 0.0001). Symptoms at consultation at PH and CCC were pain (85% and 91%, respectively; p = 0.0639), fatigue (81% and 94%, respectively; p = 0.0003), depression (51% and 69%, respectively; p = 0.0013), anxiety (47% and 75%, respectively; p < 0.0001), and well-being (63% and 93%, respectively; p < 0.0001). Multiple interventions provided: opioids, reviews for polypharmacy, constipation management, and interdisciplinary counseling. Median time from outpatient consultation to follow-up was 29 days(range, 1-119 days) at the PH and 21 days (range, 1-275 days) at the CCC (p = 0.0006). Median overall survival time from outpatient consultation was 473 days (95% confidence interval [CI], 205-699 days) at PH and 245 days (95% CI, 152-491 days) at CCC (p = 0.3408). CONCLUSIONS: Advanced cancer patients at both institutions frequently had multiple distressing physical and emotional symptoms, although the frequency was higher at CCC. The median overall survival duration was higher at the PH. More research is needed.

AB - OBJECTIVE: Thirteen-valent pneumococcal conjugate vaccines (PCV13) was licensed for optional use in mainland China since 2017, but the uptake is low. To update the research evidence for the pneumococcal serotype distribution of pre-PCV era and to estimate the potential impact of PCVs, we performed a meta-analysis on the relevant publications concerning the Chinese population. METHODS: This systematic review and meta-analysis were conducted on the pneumococcal serotype distribution publications in mainland China from 2000 to 2016. The literature was searched in PubMed, Ovid-EMBASE, Web of Science, CNKI and Wanfang. Heterogeneity and publication bias were tested by I2, meta-regression, Egger's and Begg's test. The pneumococcal serotype and vaccine serotype coverage rates were pooled using the random-effects model in Stata SE 12.0. RESULTS: In total, 85 publications were included. Of all 16,945 included pneumococcal isolates, the most common serotypes/serogroups were 19F, 19A, 23F, 14, and 6B, that from children were the same as above, that from adults>=18 years were 19, 3, 6, 23, and 14. Among isolates from children <18 years, the pooled coverage for PCV10 serotypes was 52.3%, that for PCV13 was 68.4% and that for PPSV23 was 65.5%. Regarding individuals >=18 years, the pooled coverage for PCV10 serotypes was 29.7%, that for PCV13 was 49.5% and that for PPSV23 was 50.7%. Serotype prevalence and vaccine serotype coverage varied by age group, source, and region. CONCLUSIONS: The most common pneumococcal serotype in mainland China was 19F. The serotype coverage rates of PCV13 and PPSV23 were 50%-68% in mainland China. PMID- 29451839 TI - Correlates of Postpartum Visits Among Medicaid Recipients: An Analysis Using Claims Data from a Managed Care Organization. AB - BACKGROUND: The postpartum care visit (PPCV) plays an important role in ensuring the well-being of mother and infant. This study sought to assess correlates of PPCV attendance among women who are at high risk of nonattendance. MATERIALS AND METHODS: This study used deidentified medical claims data from Virginia Premier-a nonprofit Managed Care Organization that provides health insurance for Medicaid beneficiaries. The association between various correlates and PPCV attendance was examined using multiple logistic regression analyses. RESULTS: Of the 25,692 women in the study, more than half (50.5%) did not attend a postpartum visit. Racial/ethnic minorities and women receiving the majority of their care at hospitals, Health Departments, or Federally Qualified Health Centers were more likely to attend their postpartum visit. Women who smoked and those who did not attend prenatal care had reduced odds of postpartum visit attendance. Age, education, and delivery method were not found to be significantly associated with PPCV attendance. CONCLUSIONS: Our results highlight factors associated with attendance of PPCVs in low income populations. The continued disparity in postpartum care utilization compels additional efforts to improve access to health services across socioeconomic and demographic boundaries. PMID- 29451842 TI - Protective Effect of Leaf Ethanolic Extract Etlingera hemisphaerica Blume Against Mercuric Chloride Toxicity in Blood of Mice. AB - This research was intended to investigate the protective effect of leaf ethanolic extract Etlingera hemisphaerica Blume (LE3H) against mercuric chloride (HgCl2) toxicity in blood of mice (Mus musculus). The experimental animals, 95 male M. musculus, received drink and food ad libitum. Three materials were tested: LE3H (0.13, 0.26, 0.39 mg/g body weight [bw]) was administered by gavage; HgCl2 (5 mg/kg bw) was administrated by gavage or intraperitoneal injection; and Imunos (the nutritional supplement to stimulate the immune system; 0.2 mg/g bw), as a positive control for LE3H treatment, was given by gavage. Blood samples were taken from the tails for determining number of blood cells. The animals were killed by cervical dislocation (CD), and then blood samples were collected from the hearts for protein electrophoresis. Results revealed the same number of leukocytes with LE3H (0.39 mg/g bw) treatment as with the Imunos treatment. HgCl2 administration increased leukocytes and decreased erythrocytes; HgCl2 administration followed by LE3H (0.39 mg/g bw) treatment protected the amount of blood cells as well as the control. HgCl2 administration showed a new 125 kDa protein and caused overexpression of 48 kDa protein; this protein profile could be protected by LE3H (0.39 mg/g bw) treatment as in the control condition. We conclude that LE3H provides a protective effect against HgCl2 toxicity in blood of M. musculus.

AB - Currently, 15 million informal caregivers, most of whom are women, provide care for older adults with dementia (Alzheimer's Disease Association, 2016). Caregiving for these individuals often creates distress and may adversely affect female caregivers' psychosocial and spiritual well-being. Approximately 35% of dementia caregivers complain of health deterioration after initiating caregiving responsibilities as compared to 19% of caregivers of older adults who do not have dementia (Alzheimer's Disease Association, 2016). Persons with dementia exhibit symptoms and behaviors that often are challenging for their caregivers. The way that caregivers react to these symptoms and behaviors may affect their coping repertoire and their mental health. Adequate evaluation of caregiver reactions to symptoms of dementia will provide information useful for developing targeted interventions to promote optimal health of female dementia caregivers and to potentially postpone the need for nursing home or long-term placement of the care recipient. PMID- 29451844 TI - Pulmonary Delivery of Therapeutic and Diagnostic Gases. AB - The 21st Congress for the International Society for Aerosols in Medicine included, for the first time, a session on Pulmonary Delivery of Therapeutic and Diagnostic Gases. The rationale for such a session within ISAM is that the pulmonary delivery of gaseous drugs in many cases targets the same therapeutic areas as aerosol drug delivery, and is in many scientific and technical aspects similar to aerosol drug delivery. This article serves as a report on the recent ISAM congress session providing a synopsis of each of the presentations. The topics covered are the conception, testing, and development of the use of nitric oxide to treat pulmonary hypertension; the use of realistic adult nasal replicas to evaluate the performance of pulsed oxygen delivery devices; an overview of several diagnostic gas modalities; and the use of inhaled oxygen as a proton magnetic resonance imaging (MRI) contrast agent for imaging temporal changes in the distribution of specific ventilation during recovery from bronchoconstriction. Themes common to these diverse applications of inhaled gases in medicine are discussed, along with future perspectives on development of therapeutic and diagnostic gases. PMID- 29451845 TI - Relapse of Juvenile Idiopathic Arthritis-Associated Uveitis after Discontinuation of Immunomodulatory Therapy. AB - PURPOSE: To assess treatment outcomes in juvenile idiopathic arthritis (JIA) associated uveitis and relapse rates upon discontinuation of immunomodulatory therapy (IMT). METHODS: Medical records of patients with JIA-associated uveitis seen at the University of Illinois at Chicago and the F.I. Proctor Foundation uveitis clinics from September 14, 1988 to January 5, 2011 were reviewed. The main outcome was time to relapse after attempting to discontinue IMT. RESULTS: Of 66 patients with JIA-associated uveitis, 51 (77%) received IMT as either sole or combination therapy. Of a total of 51, 41 (80%) patients achieved corticosteroid sparing control. Attempts were made to discontinue treatment in 19/51 (37%) patients. Of a total of 19 patients, 13 (68%) attempting to discontinue IMT relapsed, with a median time to relapse of 288 days from the time of attempted taper/discontinuation (IQR: 108-338). CONCLUSIONS: Corticosteroid-sparing control of inflammation was achieved in the majority of patients; however, attempts to stop IMT were often unsuccessful. Close follow-up of patients after discontinuation of therapy is warranted.

AB - The phylogenetic position of Clinostomum heluans Braun, 1899 within the genus Clinostomum Leidy, 1856 is reported in this study based on sequences of the barcoding region of the mitochondrial cytochrome c oxidase subunit 1 gene ( COX1). Additionally, molecular data are used to link the adult and the metacercariae of the species. The metacercariae of C. heluans were found encysted infecting the cichlid fish Australoheros sp. in Minas Gerais, Brazil, whereas the adults were obtained from the mouth cavity of the Great White Egret, Ardea alba, in Campeche, Mexico. The COX1 sequences obtained for the Mexican clinostomes and the Brazilian metacercaria were almost identical (0.2% molecular divergence), indicating conspecificity. Similar molecular divergence (0.2-0.4%) was found between sequences of C. heluans reported here and Clinostomum sp. 6 previously obtained from a metacercaria recovered from the cichlid Cichlasoma boliviense in Santa Cruz, Bolivia. Both maximum likelihood and Bayesian inference analyses unequivocally showed the conspecificity between C. heluans and Clinostomum sp. 6, which form a monophyletic clade with high nodal support and very low genetic divergence. Moreover, tree topology reveals that C. heluans occupies a basal position with respect to New World species of Clinostomum, although a denser taxon sampling of species within the genus is further required. The metacercaria of C. heluans seems to be specific to cichlid fish because both samples from South America were recovered from species of this fish family, although not closely related. PMID- 29451847 TI - Appropriate Use of Prophylactic Antibiotic Agents in Gynecologic Surgeries at a Midwestern Teaching Hospital. AB - BACKGROUND: The purpose of this study was to establish compliance with guidelines published by the American College of Obstetricians and Gynecologists (ACOG) regarding prophylactic antibiotic use in gynecologic surgery at our institution, and define areas of improvement to promote antibiotic stewardship. PATIENTS AND METHODS: This was a retrospective cohort study at a single, large tertiary care and teaching hospital in Kansas. Patients who underwent inpatient or outpatient gynecologic surgery during 2013 were included. Based on published guidelines for prophylactic antibiotic agents for gynecologic surgery by ACOG, procedures were classified as antibiotic-indicated or antibiotic-not-indicated. Chi-square and Fisher exact test analysis were used to identify factors associated with antibiotic use. RESULTS: Of the 1,735 cases eligible for inclusion, 1,045 (60.2%) had antibiotic agents recommended per guidelines, and appropriate antibiotic agents were given in 1,031 (98.7%) of those cases. In 690 (39.8%) cases, prophylactic antibiotics were either not recommended or the guidelines are not well defined. Of the 690 cases without indication for antibiotic agents, 394 (57.1%) received prophylactic antibiotic agents. Agreement with guidelines varied substantially based on patient age, race, insurance status, area of residence, and if the procedure was a resident case (p < 0.05). Myomectomy, laparoscopy, and ectopic pregnancy procedures received antibiotic agents against recommendations 96.3%, 75.6%, and 45.5% of the time, respectively. CONCLUSIONS: Peri-operative antibiotics are often administered inappropriately to women undergoing gynecologic surgeries for which published guidelines are not well defined. Future studies need to identify strategies to reduce antibiotic use in surgical procedures unlikely to benefit from prophylaxis. PMID- 29451848 TI - MR Imaging of Atraumatic Muscle Disorders. AB - Atraumatic disorders of skeletal muscles include congenital variants; inherited myopathies; acquired inflammatory, infectious, or ischemic disorders; neoplastic diseases; and conditions leading to muscle atrophy. These have overlapping appearances at magnetic resonance (MR) imaging and are challenging for the radiologist to differentiate. The authors organize muscle disorders into four MR imaging patterns: (a) abnormal anatomy with normal signal intensity, (b) edema/inflammation, (c) mass, and (d) atrophy, highlighting each of their key clinical and imaging findings. Anatomic muscle variants, while common, do not produce signal intensity alterations and therefore are easily overlooked. Muscle edema is the most common pattern but is nonspecific, with a broad differential diagnosis. Autoimmune, paraneoplastic, and drug-induced myositis tend to be symmetric, whereas infection, radiation-induced injury, and myonecrosis are focal asymmetric processes. Architectural distortion in the setting of muscle edema suggests one of these latter processes. Intramuscular masses include primary neoplasms, metastases, and several benign masslike lesions that simulate malignancy. Some lesions, such as lipomas, low-flow vascular malformations, fibromatoses, and subacute hematomas, are distinctive, but many intramuscular masses ultimately require a biopsy for definitive diagnosis. Atrophy is the irreversible end result of any muscle disease of sufficient severity and is the dominant finding in disorders such as the muscular dystrophies, denervation myopathy, and sarcopenia. This imaging-based classification, in correlation with clinical and laboratory data, will aid the radiologist in interpreting MR imaging findings in patients with atraumatic muscle disorders.

AB - In 2030, one in five Americans will be older than 65 years, and with that an increase in the number of individuals who experience loss in cognitive capacity is to be expected. At the same time, nutrition within the first 1000 days postconception has been suggested to strongly influence cognitive outcomes across the life-span in humans. Eggs are a primary source of both choline and the xanthophyll carotenoid lutein in the western diet, and both have been suggested to influence cognitive function in humans. This comprehensive review critically examines the effects of eggs, choline, and lutein on cognition across the life span. There seems to be clear scientific evidence to suggest that both choline and lutein play a vital role in brain and neurological development during the first 1000 days postconception. The extent to which higher intakes of choline have the potential to enhance or influence cognition during childhood, adulthood, and/or age-related cognitive decline needs further investigation. Emerging but consistent research suggests that lutein has the potential to influence cognition across the life-span and that sufficient intakes during mid to late adulthood may help to ward off age-related cognitive decline. Macular pigment optical density (MPOD) seems to be a reliable and consistent biomarker of brain lutein concentrations across the life-span and potentially one for clinically assessing cognitive status. This review summarizes the current peer-reviewed literature and existing gaps in research. PMID- 29451850 TI - Determination of 14 aminoglycosides by LC-MS/MS using molecularly imprinted polymer solid phase extraction for clean-up. AB - An LC-MS/MS method for screening 14 aminoglycosides in foodstuffs of animal origin is presented. Its scope includes raw materials and processed ingredients but also finished products composed of milk, meat, fish, egg or fat. Aminoglycosides are extracted in an acidic aqueous solution, which is first recovered after centrifugation, then diluted with a basic buffer and finally purified by molecularly imprinted polymer-solid phase extraction (MIP-SPE). Analytes are detected within 8 min by ion-pair reversed phase LC-MS/MS. Due to the large range of foodstuffs involved, the variability of matrix effects led to significant MS signal variations. This was circumvented by systematically extracting each sample twice, i.e. 'unspiked' and 'spiked' at the screening target concentration of 50 ug kg-1. The method was validated according to the European Community Reference Laboratories Residues Guidelines giving false negative and false-positive rates <=3% for all compounds. Ruggedness of the method was further demonstrated in quality control operations by a second laboratory. The 14 aminoglycosides in water-based standard solutions were stable for up to 6 months when stored at either -80 degrees C, -20 degrees C or at 4 degrees C storage temperatures. PMID- 29451851 TI - Validation of a pre-existing safety climate scale for the Turkish furniture manufacturing industry. AB - Understanding the safety climate level is essential to implement a proactive safety program. The objective of this study is to explore the possibility of having a safety climate scale for the Turkish furniture manufacturing industry since there has not been any scale available. The questionnaire recruited 783 subjects. Confirmatory factor analysis (CFA) tested a pre-existing safety scale's fit to the industry. The CFA indicated that the structures of the model present a non-satisfactory fit with the data (chi2 = 2033.4, df = 314, p <= 0.001; root mean square error of approximation = 0.08, normed fit index = 0.65, Tucker-Lewis index = 0.65, comparative fit index = 0.69, parsimony goodness-of-fit index = 0.68). The results suggest that a new scale should be developed and validated to measure the safety climate level in the Turkish furniture manufacturing industry. Due to the hierarchical structure of organizations, future studies should consider a multilevel approach in their exploratory factor analyses while developing a new scale. PMID- 29451853 TI - Graphene oxide-coated stir bar sorptive extraction of trace aflatoxins from soy milk followed by high performance liquid chromatography-laser-induced fluorescence detection. AB - Mycotoxins are potential food pollutants produced by fungi. Among them, aflatoxins (AFs) are the most toxic. Therefore, AFs were selected as models, and a sensitive, simple and green graphene oxide (GO)-based stir bar sorptive extraction (SBSE) method was developed for extraction and determination of AFs with high performance liquid chromatography-laser-induced fluorescence detector (HPLC-LIF). This method improved the sensitivity of AFs detection and solved the deposition difficulty of the direct use of GO as adsorbent. Several parameters including a spiked amount of NaCl, stirring rate, extraction time and desorption time were investigated. Under optimal conditions, the quantitative method had low limits of detection of 2.4-8.0 pg/mL, which were better than some reported AFs analytical methods. The developed method has been applied to soy milk samples with good recoveries ranging from 80.5 to 102.3%. The prepared GO-based SBSE can be used as a sensitive screening technique for detecting AFs in soy milk. PMID- 29451854 TI - Tracing Stem Cell Division in Adult Neurogenesis. AB - Neural stem cells in the ventricular-subventricular zone of the adult brain continuously generate differentiated neurons without depleting the stem cell pool.

PMID- 29451852 TI - Delta Opioids: Neuroprotective Roles in Preclinical Studies. AB - Since ancient times, opioids have been used clinically and abused recreationally. In the early stages (about 1,000 AD) of opium history, an Arab physician, Avicenna, administered opioids to control diarrhea and eye diseases. 1 Opioids have very strong pain relieving properties and they also regulate numerous cellular responses. Opioid receptors are expressed throughout the body, including the nervous system, heart, lungs, liver, gastrointestinal tract, and retina. 2-6 Delta opioid receptors (DORs) are a very attractive target from the perspective of both receptor function and their therapeutic potential. Due to a rapid progress in mouse mutagenesis and development of small molecules as DOR agonist, novel functions and roles of DORs have emerged in recent years. This review article focuses on the recent advances in the neuroprotective roles of DOR agonists in general and retina neuroprotection in particular. Rather than being exhaustive, this review highlights the selected studies of DOR function in neuroprotection. We also highlight our preclinical studies using rodent models to demonstrate the potentials of DOR agonists for retinal neuroprotection. Based on existing literature and our recently published data on the eye, DOR agonists possess therapeutic abilities that protect the retina and optic nerve injury against glaucoma and perhaps other retinopathies as well. This review also highlights the signaling events associated with DOR for neuroprotection in the eye. There is a need for translational research on DORs to recognize their potential for clinical application such as in glaucoma. PMID- 29451855 TI - In Vivo Labeling by CD73 Marks Multipotent Stromal Cells and Highlights Endothelial Heterogeneity in the Bone Marrow Niche. AB - Despite much work studying ex vivo multipotent stromal cells (MSCs), the identity and characteristics of MSCs in vivo are not well defined. Here, we generated a CD73-EGFP reporter mouse to address these questions and found EGFP+ MSCs in various organs. In vivo, EGFP+ mesenchymal cells were observed in fetal and adult bones at proliferative ossification sites, while in solid organs EGFP+ cells exhibited a perivascular distribution pattern. EGFP+ cells from the bone compartment could be clonally expanded ex vivo from single cells and displayed trilineage differentiation potential. Moreover, in the central bone marrow CD73 EGFP+ specifically labeled sinusoidal endothelial cells, thought to be a critical component of the hematopoietic stem cell niche. Purification and molecular characterization of this CD73-EGFP+ population revealed an endothelial subtype that also displays a mesenchymal signature, highlighting endothelial cell heterogeneity in the marrow. Thus, the CD73-EGFP mouse is a powerful tool for studying MSCs and sinusoidal endothelium.

PMID- 29451857 TI - MicroRNAs as predictive biomarkers of response to tyrosine kinase inhibitor therapy in metastatic renal cell carcinoma. AB - Renal cell carcinoma (RCC) accounts for 2%-3% of all malignant tumours. The first choice treatment in metastatic RCC (mRCC) patients is tyrosine kinase inhibitors (TKIs). Although TKIs may prolong survival of the treated patients who are not primary resistant, almost all of them will eventually develop secondary resistance to the treatment after a progression-free period. To predict treatment response, thus, we need efficient biomarkers for rational indication of TKIs in mRCC. MicroRNAs (miRNAs) not only play important roles in the pathogenesis of many cancers, including RCC but also have been shown to serve as promising diagnostic, prognostic and predictive biomarkers in various cancers. However, the potential of miRNAs to predict response to therapy with TKIs in mRCC has not yet gained sufficient attention. Because personalisation of the TKIs indication in mRCC presents an important unmet medical need, we summarise research on this topic and give an overall insight on the current knowledge in this field. PMID- 29451858 TI - Cerebrospinal fluid microRNAs as diagnostic biomarkers in brain tumors. AB - Cerebrospinal fluid (CSF) is a body fluid that has many important functions and is in direct contact with the extracellular environment of the central nervous system (CNS). CSF serves as both the communication channel allowing the distribution of various substances among the CNS cells and the storage facility for the waste products these cells release. For these reasons, CSF is a potential source of diagnostic biomarkers of many CNS diseases, including brain tumors. Recent studies have revealed that CSF also contains circulating microRNAs (miRNAs), short non-coding RNAs that have been described as biomarkers in many cancers. However, CSF miRNAs are difficult to detect, which is why researchers face major challenges, including technological difficulties in its detection and its lack of standardization. Therefore, this review aims (i) to highlight the potential of CSF miRNAs as diagnostic, prognostic and predictive biomarkers in brain tumors, and (ii) to summarize technological approaches for detection of CSF miRNAs.

PMID- 29451860 TI - A hierarchical Bayesian tri-variate analysis on factors associated with anthropometric measures in a large sample of children and adolescents: the CASPIAN-IV study. AB - BACKGROUND: This study aimed to assess determinants of anthropometric measures in a nationally representative sample of Iranian children and adolescents. METHODS: This nationwide study was conducted among 13,280 students, aged 6-18 years, who were randomly selected from 30 provinces in Iran. Anthropometric measures were determined by calibrated instruments. Demographic and socio-economic (SES) variables, lifestyle behaviors, family history of chronic disease and prenatal factors were studied, as well. A hierarchical Bayesian tri-variate analysis was used to assess the factors associated with obesity measures of the body mass index (BMI), waist-to-height ratio (WHtR) and wrist circumference (WrC). RESULTS: The results showed that the BMI was associated with SES score, family history of obesity, family history of diabetes mellitus, physical inactivity, screen time, duration of sleep, breakfast consumption, birth weight, breastfeeding, junk food and place of residence (urban-rural). All these factors were also significantly associated with WrC except for consumption of junk food. Many of these factors had a partial but significant relationship with WHtR. CONCLUSIONS: Various factors contribute to obesity. Preventive and educational programs on manageable factors such as increasing physical activity, eating breakfast and limiting TV or screen time could be helpful in controlling obesity in schoolchildren and reducing associated complications.

PMID- 29451862 TI - Neonatal resuscitation experience curves: simulation based mastery learning booster sessions and skill decay patterns among pediatric residents. AB - Background Following neonatal resuscitation program (NRP) training, decay in clinical skills can occur. Simulation-based deliberate practice (SBDP) has been shown to maintain NRP skills to a variable extent. Our study objectives were (a) to determine whether a single 30 min simulation-based intervention that incorporates SBDP and mastery learning (ML) can effectively restore skills and prevent skill decay and (b) to compare different timing options. Methods Following NRP certification, pediatric residents were randomly assigned to receive a video-recorded baseline assessment plus SBDP-ML refresher education at between 6 and 9 months (early) or between 9 and 12 months (late). One year following initial certification, participants had repeat skill retention videotaped evaluations. Participants were scored by blinded NRP instructors using validated criteria scoring tools and assigned a global performance rating score (GRS). Results Twenty-seven participants were included. Residents in both early and late groups showed significant skill decay 7 and 10 months after initial NRP. SBDP-ML booster sessions significantly improved participants' immediate NRP performance scores (p<0.001), which persisted for 2 months, but were again lower 4 months later. Conclusions NRP skills may be boosted to mastery levels after a short SBDP-ML intervention and do not appear to significantly decline after 2 months. Brief booster training could potentially serve as a useful supplement to traditional NRP training for pediatric residents.

AB - Despite the well-documented benefits of Combretum fragrans in Cameroon, only few scientific works have been done on it. In this study we isolated eight compounds from the leaves extract of C. fragrans: velutin (1), belamcanidin (2), cirsilineol (3), cirsimaritin (4), 3beta-acetoxy-20,24-epoxy-11,25-hydroxy dammarane (5), combretin A (6), combretin B (7) and a mixture of arjunolic acid (8a) and asiatic acid (8b). Compounds 6 and 7 presented potent anti-inflammatory, antioxidant and antidiabetic activities. Compounds 1, 3, 5 and the mixture of 8a and 8b were significantly active, and compounds 2 and 4 presented moderate activity for reactive oxygen species inhibitory and free-radical scavenging. All compounds were isolated using chromatographic techniques; their structures were elucidated by spectroscopic techniques and their spectroscopic data compared with those of the literature. Anti-inflammatory activity was evaluated via the oxidative burst assay using a luminol-amplified chemiluminescence technique, antioxidant activity by free-radical scavenging activity (DPPH) and antidiabetic activity via alpha-glucosidase inhibition. All of the isolated compounds (1-8) were reported to exhibit significant antioxidant activity. Compounds 1, 3, and 5 8 exhibited potent chemiluminescence inhibition effect, and only compounds 6 and 7 inhibited alpha-glucosidase. Thus, C. fragrans can be used as an effective natural source of anti-inflammatory, antioxidant and antidiabetic compounds. PMID- 29451866 TI - High mobility In0.75Ga0.25As quantum wells in an InAs phonon lattice. AB - InGaAs based devices are great complements to silicon for CMOS, as they provide an increased carrier saturation velocity, lower operating voltage and reduced power dissipation (International technology roadmap for semiconductors (www.itrs2.net)). In this work we show that In0.75Ga0.25As quantum wells with a high mobility, 15 000 to 20 000 cm2 V-1 s-1 at ambient temperature, show an InAs like phonon with an energy of 28.8 meV, frequency of 232 cm-1 that dominates the polar-optical mode scattering from ~70 K to 300 K. The measured optical phonon frequency is insensitive to the carrier density modulated with a surface gate or LED illumination. We model the electron scattering mechanisms as a function of temperature and identify mechanisms that limit the electron mobility in In0.75Ga0.25As quantum wells. Background impurity scattering starts to dominate for temperatures <100 K. In the high mobility In0.75Ga0.25As quantum well, GaAs like phonons do not couple to the electron gas unlike the case of In0.53Ga0.47As quantum wells. PMID- 29451867 TI - Determination of Debye temperatures and Lamb-Mossbauer factors for LnFeO3 orthoferrite perovskites (Ln = La, Nd, Sm, Eu, Gd). AB - Lanthanide orthoferrites have wide-ranging industrial uses including solar, catalytic and electronic applications. Here a series of lanthanide orthoferrite perovskites, LnFeO3 (Ln = La; Nd; Sm; Eu; Gd), prepared through a standard stoichiometric wet ball milling route using oxide precursors, has been studied. Characterisation through x-ray diffraction and x-ray fluorescence confirmed the synthesis of phase-pure or near-pure LnFeO3 compounds. 57Fe Mossbauer spectroscopy was performed over a temperature range of 10 K-293 K to observe hyperfine structure and to enable calculation of the recoil-free fraction and Debye temperature (theta D) of each orthoferrite. Debye temperatures (Ln = La 474 K; Nd 459 K; Sm 457 K; Eu 452 K; Gd 473 K) and recoil-free fractions (Ln = La 0.827; Nd 0.817; Sm 0.816; Eu 0.812; Gd 0.826) were approximated through minimising the difference in the temperature dependent experimental centre shift and theoretical isomer shift, by allowing the Debye temperature and isomer shift values to vary. This method of minimising the difference between theoretical and actual values yields Debye temperatures consistent with results from other studies determined through thermal analysis methods. This displays the ability of variable-temperature Mossbauer spectroscopy to approximate Debye temperatures and recoil-free fractions, whilst observing temperature induced transitions over the temperature range observed. X-ray diffraction and Rietveld refinement show an inverse relationship between FeO6 octahedral volume and approximated Debye temperatures. Raman spectroscopy show an increase in the band positions attributed to soft modes of Ag symmetry, Ag(3) and Ag(5) from La to GdFeO3 corresponding to octahedral rotations and tilts in the [0 1 0] and [1 0 1] planes respectively. PMID- 29451868 TI - Suppression of material transfer at contacting surfaces: the effect of adsorbates on Al/TiN and Cu/diamond interfaces from first-principles calculations. AB - The effect of monolayers of oxygen (O) and hydrogen (H) on the possibility of material transfer at aluminium/titanium nitride (Al/TiN) and copper/diamond (Cu/Cdia) interfaces, respectively, were investigated within the framework of density functional theory (DFT). To this end the approach, contact, and subsequent separation of two atomically flat surfaces consisting of the aforementioned pairs of materials were simulated. These calculations were performed for the clean as well as oxygenated and hydrogenated Al and Cdia surfaces, respectively. Various contact configurations were considered by studying several lateral arrangements of the involved surfaces at the interface. Material transfer is typically possible at interfaces between the investigated clean surfaces; however, the addition of O to the Al and H to the Cdia surfaces was found to hinder material transfer. This passivation occurs because of a significant reduction of the adhesion energy at the examined interfaces, which can be explained by the distinct bonding situations. PMID- 29451869 TI - Use of an Alternating Inflatable Head Pad inPatients Undergoing Open Heart Surgery. AB - BACKGROUND Preoperative symptoms like occipital pressure ulcers and alopecia areata (AA) significantly lowered patient quality of life. Therefore, preoperative nursing was in need of investigation. This study aimed to compare effects of an alternating inflatable head pad and a gel pad on occurrence of postoperative pressure ulcers and AA in patients undergoing open heart surgery. MATERIAL AND METHODS This was a prospective study. We allocated randomly 120 patients undergoing surgery (3-7 h) in the Yantai Yuhuangding Hospital affiliated to Qingdao University, China from January to October 2015 to the control (gel head pad) or the experimental (alternating inflatable head pad) group (n=60 per group). The incidence and severity of occipital pressure ulcer were graded by the classification system of the European Pressure Ulcer Advisory Panel (EPUAP). The degree of occipital alopecia was measured by hair pull test. This study used the t test and chi-square analysis. All statistics were analyzed by SPSS 21.0. RESULTS Compared with the control group, there was a significantly lower incidence and severity of occipital pressure ulcer and alopecia in the experimental group (9 cases/60 cases vs. 1 case/60 cases, P<0.01). Moreover, multivariate analysis showed the risk of developing occipital pressure ulcer after surgery was also obviously lower in the experimental group (OR 1.449 120.798; P<0.005). Hair pull test revealed that fewer patients in the experimental group had a hair loss over 10%. CONCLUSIONS The alternating inflatable head pad was effective in reducing the incidence and severity of occipital pressure ulcer and alopecia associated with surgery, which benefited the postoperative nursing and improved patient quality of life. PMID- 29451870 TI - Long-term efficacy and safety of rilpivirine plus abacavir and lamivudine in HIV 1 infected patients with undetectable viral load. AB - INTRODUCTION: A regimen with rilpivirine (RPV), abacavir (ABC) and lamivudine (3TC) is simple and may allow the sparing of tenofovir and protease inhibitors. However, data on use of this combination as a strategy of switch are limited. Aims of the study were to assess the long-term efficacy and safety of this regimen. METHODS: Retrospective study on HIV-1 infected patients followed at the Infectious Disease Department of the San Raffaele Scientific Institute, HBsAg negative, HLA B5701-negative, with no documented resistance to RPV, ABC and 3TC, with HIV-RNA<50 copies/mL who started RPV plus ABC/3TC from March 2013 to September 2015. The primary outcome was durability [no treatment failure (TF)]. Secondary objectives were to evaluate changes in immunological, metabolic and other safety parameters. TF was defined as the occurrence of virological failure (VF, 2 consecutive values >50 copies/mL) or discontinuation of any drug in the regimen for any reason. Patients' follow-up accrued from the date of RPV plus ABC/3TC initiation to the date of TF (VF or discontinuation of any drug in the regimen) or to the date of last available visit. Time to TF was evaluated by use of the Kaplan-Meier curves. Mixed linear models were applied to evaluate changes in immunological, metabolic and other safety parameters. RESULTS AND DISCUSSION: In this analysis, 100 patients starting RPV plus ABC/3TC were included. By 12, 24 and 36 months after switching to RPV plus ABC/3TC, the proportions of individuals without TF were 88% [95% confidence interval (CI): 79%-93%], 82% (95% CI:73%-89%) and 78% (95% CI:68%-86%), respectively. Time to TF was not significantly influenced by CD4+ nadir (<=200 vs >200 cells/MUl; log-rank test: p = 0.311) or pre-ART viral load (<100000 vs >=100000 copies/mL; log-rank test: p = 0.574) or the type of previous antiretroviral regimen (PI+2NRTIs vs NNRTI+2NRTIs vs Other; log-rank test: p = 0.942). Over a median follow-up of 2.9 years (IQR: 1.9-3.5), 26 subjects discontinued the treatment [10 due to toxicity, 7 for interactions with other drugs, 3 due to cardiovascular risk concern, 2 due to single viral blip, 1 due to VF, 1 for asthma, 1 patient's decision, 1 due to enrolment in a study protocol]. CONCLUSIONS: In this retrospective study, long-term use of RPV plus ABC/3TC regimen is effective and safe. Efficacy of this regimen was not found to be affected by low CD4+ nadir or high pre-ART viral load.

AB - We assessed the relative importance of dispersal limitation, environmental heterogeneity and their joint effects as determinants of the spatial patterns of 229 species in the moist tropical forest of Barro Colorado Island (Panama). We differentiated five types of species according to their dispersal syndrome; autochorous, anemochorous, and zoochorous species with small, medium-size and large fruits. We characterized the spatial patterns of each species and we checked whether they were best fitted by Inhomogeneous Poisson (IPP), Homogeneous Poisson cluster (HPCP) and Inhomogeneous Poisson cluster processes (IPCP) by means of the Akaike Information Criterion. We also assessed the influence of species' dispersal mode in the average cluster size. We found that 63% of the species were best fitted by IPCP regardless of their dispersal syndrome, although anemochorous species were best described by HPCP. Our results indicate that spatial patterns of tree species in this forest cannot be explained only by dispersal limitation, but by the joint effects of dispersal limitation and environmental heterogeneity. The absence of relationships between dispersal mode and degree of clustering suggests that several processes modify the original spatial pattern generated by seed dispersal. These findings emphasize the importance of fitting point process models with a different biological meaning when studying the main determinants of spatial structure in plant communities.

AB - Category-selective brain areas exhibit varying levels of neural activity to ipsilaterally presented stimuli. However, in face- and house-selective areas, the neural responses evoked by ipsilateral stimuli in the peripheral visual field remain unclear. In this study, we displayed face and house images using a wide view visual presentation system while performing functional magnetic resonance imaging (fMRI). The face-selective areas (fusiform face area (FFA) and occipital face area (OFA)) exhibited intense neural responses to ipsilaterally presented images, whereas the house-selective areas (parahippocampal place area (PPA) and transverse occipital sulcus (TOS)) exhibited substantially smaller and even negative neural responses to the ipsilaterally presented images. We also found that the category preferences of the contralateral and ipsilateral neural responses were similar. Interestingly, the face- and house-selective areas exhibited neural responses to ipsilateral images that were smaller than the responses to the contralateral images. Multi-voxel pattern analysis (MVPA) was implemented to evaluate the difference between the contralateral and ipsilateral responses. The classification accuracies were much greater than those expected by chance. The classification accuracies in the FFA were smaller than those in the PPA and TOS. The closer eccentricities elicited greater classification accuracies in the PPA and TOS. We propose that these ipsilateral neural responses might be interpreted by interhemispheric communication through intrahemispheric connectivity of white matter connection and interhemispheric connectivity via the corpus callosum and occipital white matter connection. Furthermore, the PPA and TOS likely have weaker interhemispheric communication than the FFA and OFA, particularly in the peripheral visual field. PMID- 29451873 TI - In silico analysis of antibiotic-induced Clostridium difficile infection: Remediation techniques and biological adaptations. AB - In this paper we study antibiotic-induced C. difficile infection (CDI), caused by the toxin-producing C. difficile (CD), and implement clinically-inspired simulated treatments in a computational framework that synthesizes a generalized Lotka-Volterra (gLV) model with SIR modeling techniques. The gLV model uses parameters derived from an experimental mouse model, in which the mice are administered antibiotics and subsequently dosed with CD. We numerically identify which of the experimentally measured initial conditions are vulnerable to CD colonization, then formalize the notion of CD susceptibility analytically. We simulate fecal transplantation, a clinically successful treatment for CDI, and discover that both the transplant timing and transplant donor are relevant to the the efficacy of the treatment, a result which has clinical implications. We incorporate two nongeneric yet dangerous attributes of CD into the gLV model, sporulation and antibiotic-resistant mutation, and for each identify relevant SIR techniques that describe the desired attribute. Finally, we rely on the results of our framework to analyze an experimental study of fecal transplants in mice, and are able to explain observed experimental results, validate our simulated results, and suggest model-motivated experiments. PMID- 29451874 TI - A stochastic and dynamical view of pluripotency in mouse embryonic stem cells. AB - Pluripotent embryonic stem cells are of paramount importance for biomedical sciences because of their innate ability for self-renewal and differentiation into all major cell lines. The fateful decision to exit or remain in the pluripotent state is regulated by complex genetic regulatory networks. The rapid growth of single-cell sequencing data has greatly stimulated applications of statistical and machine learning methods for inferring topologies of pluripotency regulating genetic networks. The inferred network topologies, however, often only encode Boolean information while remaining silent about the roles of dynamics and molecular stochasticity inherent in gene expression. Herein we develop a framework for systematically extending Boolean-level network topologies into higher resolution models of networks which explicitly account for the promoter architectures and gene state switching dynamics. We show the framework to be useful for disentangling the various contributions that gene switching, external signaling, and network topology make to the global heterogeneity and dynamics of transcription factor populations. We find the pluripotent state of the network to be a steady state which is robust to global variations of gene switching rates which we argue are a good proxy for epigenetic states of individual promoters. The temporal dynamics of exiting the pluripotent state, on the other hand, is significantly influenced by the rates of genetic switching which makes cells more responsive to changes in extracellular signals.

AB - BACKGROUND: Timely linkage to care after HIV diagnosis is crucial as delayed access can result in poor patient outcomes. The aim of this systematic review was to synthesise the evidence to achieve a better understanding of what proportion of patients are linked to care and what factors impact linkage. METHODS: Systematic searches were run in six databases up to the end of February 2017. The grey literature was also reviewed. Inclusion criteria were: sample size >=50 people (aged >=15), from the WHO European Region, published 2006-2017 and in English. Linkage to care was defined as a patient seen for HIV care after diagnosis. Study selection, data extraction and quality assurance were performed by two independent reviewers. Random-effects meta-analysis was carried out to summarise linkage to care within three months of diagnosis. RESULTS: Twenty-four studies were included; 22 presented linkage to care data and seven examined factors for linkage. Linkage among 89,006 people in 19 countries was captured. Meta-analysis, restricted to 12 studies and measuring prompt linkage within three months, gave a pooled estimate of 85% (95% CI: 75%-93%). Prompt linkage was higher in studies including only people in care (94%; 95% CI: 91%-97%) than in those of all new diagnoses (71%; 95% CI: 50%-87%). Heterogeneity was high across and within strata (>99%). Factors associated with delaying or not linking to care included: acquiring HIV through heterosexual contact/injecting drug use, younger age at diagnosis, lower levels of education, feeling well at diagnosis and diagnosis outside an STI clinic. CONCLUSION: Overall, linkage to care was high, though estimates were lower in studies with a high proportion of people who inject drugs. The high heterogeneity between studies made it challenging to synthesise findings. Studies should adopt a standardised definition with a three month cut-off to measure prompt linkage to care to ensure comparability. PMID- 29451877 TI - Influence of hyperbaric oxygen on biomechanics and structural bone matrix in type 1 diabetes mellitus rats. AB - BACKGROUND: The aim of this study was to evaluate the biomechanics and structural bone matrix in diabetic rats subjected to hyperbaric oxygen therapy (HBO). METHODS: Twenty-four male rats were divided into the following groups: Control; Control + HBO; Diabetic, and Diabetic + HBO. Diabetes was induced with streptozotocin (STZ) in the diabetic Groups. After 30 days, HBO was performed every 48h in HBO groups and all animals were euthanized 60 days after diabetic induction. The femur was submitted to a biomechanical (maximum strength, energy to-failure and stiffness) and Attenuated Total Reflectance Fourier transform infrared (ATR-FTIR) analyses (crosslink ratio, crystallinity index, matrix-to mineral ratio: Amide I + II/Hydroxyapatite (M:MI) and Amide III + Collagen/HA (M:MIII)). RESULTS: In biomechanical analysis, diabetic animals showed lower values of maximum strength, energy and stiffness than non-diabetic animals. However, structural strength and stiffness were increased in groups with HBO compared with non-HBO. ATR-FTIR analysis showed decreased collagen maturity in the ratio of crosslink peaks in diabetic compared with the other groups. The bone from the diabetic groups showed decreased crystallinity compared with non diabetic groups. M:MI showed no statistical difference between groups. However, M:MIII showed an increased matrix mineral ratio in diabetic+HBO and control+HBO compared with control and diabetic groups. Correlations between mechanical and ATR-FTIR analyses showed significant positive correlation between collagen maturity and stiffness. CONCLUSIONS: Diabetes decreased collagen maturation and the mineral deposition process, thus reducing biomechanical properties. Moreover, the study showed that HBO improved crosslink maturation and increased maximum strength and stiffness in the femur of T1DM animals. PMID- 29451876 TI - Comparative genomic analysis of the multispecies probiotic-marketed product VSL#3. AB - Several probiotic-marketed formulations available for the consumers contain live lactic acid bacteria and/or bifidobacteria. The multispecies product commercialized as VSL#3 has been used for treating various gastro-intestinal disorders. However, like many other products, the bacterial strains present in VSL#3 have only been characterized to a limited extent and their efficacy as well as their predicted mode of action remain unclear, preventing further applications or comparative studies. In this work, the genomes of all eight bacterial strains present in VSL#3 were sequenced and characterized, to advance insights into the possible mode of action of this product and also to serve as a basis for future work and trials. Phylogenetic and genomic data analysis allowed us to identify the 7 species present in the VSL#3 product as specified by the manufacturer. The 8 strains present belong to the species Streptococcus thermophilus, Lactobacillus acidophilus, Lactobacillus paracasei, Lactobacillus plantarum, Lactobacillus helveticus, Bifidobacterium breve and B. animalis subsp. lactis (two distinct strains). Comparative genomics revealed that the draft genomes of the S. thermophilus and L. helveticus strains were predicted to encode most of the defence systems such as restriction modification and CRISPR-Cas systems. Genes associated with a variety of potential probiotic functions were also identified. Thus, in the three Bifidobacterium spp., gene clusters were predicted to encode tight adherence pili, known to promote bacteria-host interaction and intestinal barrier integrity, and to impact host cell development. Various repertoires of putative signalling proteins were predicted to be encoded by the genomes of the Lactobacillus spp., i.e. surface layer proteins, LPXTG-containing proteins, or sortase-dependent pili that may interact with the intestinal mucosa and dendritic cells. Taken altogether, the individual genomic characterization of the strains present in the VSL#3 product confirmed the product specifications, determined its coding capacity as well as identified potential probiotic functions. PMID- 29451878 TI - Control fast or control smart: When should invading pathogens be controlled? AB - The intuitive response to an invading pathogen is to start disease management as rapidly as possible, since this would be expected to minimise the future impacts of disease. However, since more spread data become available as an outbreak unfolds, processes underpinning pathogen transmission can almost always be characterised more precisely later in epidemics. This allows the future progression of any outbreak to be forecast more accurately, and so enables control interventions to be targeted more precisely. There is also the chance that the outbreak might die out without any intervention whatsoever, making prophylactic control unnecessary. Optimal decision-making involves continuously balancing these potential benefits of waiting against the possible costs of further spread. We introduce a generic, extensible data-driven algorithm based on parameter estimation and outbreak simulation for making decisions in real-time concerning when and how to control an invading pathogen. The Control Smart Algorithm (CSA) resolves the trade-off between the competing advantages of controlling as soon as possible and controlling later when more information has become available. We show-using a generic mathematical model representing the transmission of a pathogen of agricultural animals or plants through a population of farms or fields-how the CSA allows the timing and level of deployment of vaccination or chemical control to be optimised. In particular, the algorithm outperforms simpler strategies such as intervening when the outbreak size reaches a pre-specified threshold, or controlling when the outbreak has persisted for a threshold length of time. This remains the case even if the simpler methods are fully optimised in advance. Our work highlights the potential benefits of giving careful consideration to the question of when to start disease management during emerging outbreaks, and provides a concrete framework to allow policy-makers to make this decision. PMID- 29451879 TI - Dengue knowledge, attitudes and practices and their impact on community-based vector control in rural Cambodia. AB - BACKGROUND: Globally there are an estimated 390 million dengue infections per year, of which 96 million are clinically apparent. In Cambodia, estimates suggest as many as 185,850 cases annually. The World Health Organization global strategy for dengue prevention aims to reduce mortality rates by 50% and morbidity by 25% by 2020. The adoption of integrated vector management approach using community based methods tailored to the local context is one of the recommended strategies to achieve these objectives. Understanding local knowledge, attitudes and practices is therefore essential to designing suitable strategies to fit each local context. METHODS AND FINDINGS: A Knowledge, Attitudes and Practices survey in 600 randomly chosen households was administered in 30 villages in Kampong Cham which is one of the most populated provinces of Cambodia. KAP surveys were administered to a sub-sample of households where an entomology survey was conducted (1200 households), during which Aedes larval/pupae and adult female Aedes mosquito densities were recorded. Participants had high levels of knowledge regarding the transmission of dengue, Aedes breeding, and biting prevention methods; the majority of participants believed they were at risk and that dengue transmission is preventable. However, self-reported vector control practices did not match observed practices recorded in our surveys. No correlation was found between knowledge and observed practices either. CONCLUSION: An education campaign regarding dengue prevention in this setting with high knowledge levels is unlikely to have any significant effect on practices unless it is incorporated in a more comprehensive strategy for behavioural change, such a COMBI method, which includes behavioural models as well as communication and marketing theory and practice. TRIAL REGISTRATION: ISRCTN85307778. PMID- 29451880 TI - Apolipoprotein E genotype does not moderate the associations of depressive symptoms, neuroticism and allostatic load with cognitive ability and cognitive aging in the Lothian Birth Cohort 1936. AB - OBJECTIVES: In this replication-and-extension study, we tested whether depressive symptoms, neuroticism, and allostatic load (multisystem physiological dysregulation) were related to lower baseline cognitive ability and greater subsequent cognitive decline in older adults, and whether these relationships were moderated by the E4 allele of the apolipoprotein E (APOE) gene. We also tested whether allostatic load mediated the relationships between neuroticism and cognitive outcomes. METHODS: We used data from the Lothian Birth Cohort 1936 (n at Waves 1-3: 1,028 [M age = 69.5 y]; 820 [M duration since Wave 1 = 2.98 y]; 659 [M duration since Wave 1 = 6.74 y]). We fitted latent growth curve models of general cognitive ability (modeled using five cognitive tests) with groups of APOE E4 non-carriers and carriers. In separate models, depressive symptoms, neuroticism, and allostatic load predicted baseline cognitive ability and subsequent cognitive decline. In addition, models tested whether allostatic load mediated relationships between neuroticism and cognitive outcomes. RESULTS: Baseline cognitive ability had small-to-moderate negative associations with depressive symptoms (beta range = -0.20 to -0.17), neuroticism (beta range = 0.27 to -0.23), and allostatic load (beta range = -0.11 to 0.09). Greater cognitive decline was linked to baseline allostatic load (beta range = -0.98 to 0.83) and depressive symptoms (beta range = -1.00 to -0.88). However, APOE E4 allele possession did not moderate the relationships of depressive symptoms, neuroticism and allostatic load with cognitive ability and cognitive decline. Additionally, the associations of neuroticism with cognitive ability and cognitive decline were not mediated through allostatic load. CONCLUSIONS: Our results suggest that APOE E4 status does not moderate the relationships of depressive symptoms, neuroticism, and allostatic load with cognitive ability and cognitive decline in healthy older adults. The most notable positive finding in the current research was the strong association between allostatic load and cognitive decline. PMID- 29451881 TI - Population-based coverage survey results following the mass drug administration of azithromycin for the treatment of trachoma in Amhara, Ethiopia. AB - BACKGROUND: Trachoma is the leading infectious cause of blindness worldwide. In communities where the district level prevalence of trachomatous inflammation follicular among children ages 1-9 years is >=5%, WHO recommends annual mass drug administration (MDA) of antibiotics with the aim of at least 80% coverage. Population-based post-MDA coverage surveys are essential to understand the effectiveness of MDA programs, yet published reports from trachoma programs are rare. METHODS: In the Amhara region of Ethiopia, a population-based MDA coverage survey was conducted 3 weeks following the 2016 MDA to estimate the zonal prevalence of self-reported drug coverage in all 10 administrative zones. Survey households were selected using a multi-stage cluster random sampling design and all individuals in selected households were presented with a drug sample and asked about taking the drug during the campaign. Zonal estimates were weighted and confidence intervals were calculated using survey procedures. Self-reported drug coverage was then compared with regional reported administrative coverage. RESULTS: Region-wide, 24,248 individuals were enumerated, of which, 20,942 (86.4%) individuals were present. The regional self-reported antibiotic coverage was 76.8% (95%Confidence Interval (CI):69.3-82.9%) in the population overall and 77.4% (95%CI = 65.7-85.9%) among children ages 1-9 years old. Zonal coverage ranged from 67.8% to 90.2%. Five out of 10 zones achieved a coverage >80%. In all zones, the reported administrative coverage was greater than 90% and was considerably higher than self-reported MDA coverage. Main reasons reported for MDA campaign non-attendance included being physically unable to get to MDA site (22.5%), traveling (20.6%), and not knowing about the campaign (21.0%). MDA refusal was low (2.8%) in this population. CONCLUSIONS: Although self-reported MDA coverage in Amhara was greater than 80% in some zones, programmatic improvements are warranted throughout Amhara to achieve higher coverage. These results will be used to enhance community mobilization and improve training for MDA distributors and supervisors to improve coverage in future MDAs. PMID- 29451882 TI - De novo transcriptomic analysis of leaf and fruit tissue of Cornus officinalis using Illumina platform. AB - Cornus officinalis is one of the most widely used medicinal plants in China and other East Asian countries to cure diseases such as liver, kidney, cardiovascular diseases and frequent urination for thousands of years. It is a Level 3 protected species, and is one of the 42 national key protected wild species of animals and plants in China. However, the genetics and molecular biology of C. officinalis are poorly understood, which has hindered research on the molecular mechanism of its metabolism and utilization. Hence, enriching its genomic data and information is very important. In recent years, the fast-growing technology of next generation sequencing has provided an effective path to gain genomic information from nonmodel species. This study is the first to explore the leaf and fruit tissue transcriptome of C. officinalis using the Illumina HiSeq 4000 platform. A total of 57,954,134 and 60,971,652 clean reads from leaf and fruit were acquired, respectively (GenBank number SRP115440). The pooled reads from all two libraries were assembled into 56,392 unigenes with an average length 856 bp. Among these, 41,146 unigenes matched with sequences in the NCBI nonredundant protein database. The Gene Ontology database assigned 24,336 unigenes with biological process (83.26%), cellular components (53.58%), and molecular function (83.93%). In addition, 10,808 unigenes were assigned a KOG functional classification by the KOG database. Searching against the KEGG pathway database indicated that 18,435 unigenes were mapped to 371 KEGG pathways. Moreover, the edgeR database identified 4,585 significant differentially expressed genes (DEGs), of which 1,392 were up-regulated and 3,193 were down-regulated in fruit tissue compared with leaf tissue. Finally, we explored 581 transcription factors with 50 transcription factor gene families. Most DEGs and transcription factors were related to terpene biosynthesis and secondary metabolic regulation. This study not only represented the first de novo transcriptomic analysis of C. officinalis but also provided fundamental information on its genes and biosynthetic pathway. These findings will help us explore the molecular metabolism mechanism of terpene biosynthesis in C. officinalis. PMID- 29451883 TI - Management of post abortion complications in Botswana -The need for a standardized approach. AB - BACKGROUND: Post abortion complications are the third leading cause of maternal death after hemorrhage and hypertension in Botswana where abortion is not legalized. This study aimed at assessing the management of post abortion complications in Botswana. METHODS: A retrospective study was conducted at four hospitals in Botswana in 2014. Socio-demographic, patient management and outcomes data were extracted from patients' medical records. Descriptive statistics and chi-square test were used to analyze and present the data. RESULT: A total of 619 patients' medical records were reviewed. The duration of hospital stay prior to uterine evacuation ranged from less than an hour to 480 hours. All the patients received either prophylactic or therapeutic antibiotics. Use of parenteral antibiotics was significantly associated with severity of abortion, second trimester abortion, use of blood products and the interval between management's decision and uterine evacuation. Uterine evacuation for retained products of conception was achieved by metallic curettage among 516 (83.4%) patients and by vacuum aspiration in 18 (2.9%). At all the study sites, Misoprostol or Oxytocin were used concurrently with surgical evacuation of the uterus. None use of analgesics or anesthetics in the four hospitals ranged between 12.4% to 28.8%. CONCLUSION: There is evidence of delayed patient care and prolonged hospital stay. Metallic curette was the primary method used for uterine evacuation across all the facilities. Pain management and antibiotics use was not standardized. A protocol has to be developed with the aim of standardizing post abortion care. PMID- 29451884 TI - A damped oscillator imposes temporal order on posterior gap gene expression in Drosophila. AB - Insects determine their body segments in two different ways. Short-germband insects, such as the flour beetle Tribolium castaneum, use a molecular clock to establish segments sequentially. In contrast, long-germband insects, such as the vinegar fly Drosophila melanogaster, determine all segments simultaneously through a hierarchical cascade of gene regulation. Gap genes constitute the first layer of the Drosophila segmentation gene hierarchy, downstream of maternal gradients such as that of Caudal (Cad). We use data-driven mathematical modelling and phase space analysis to show that shifting gap domains in the posterior half of the Drosophila embryo are an emergent property of a robust damped oscillator mechanism, suggesting that the regulatory dynamics underlying long- and short germband segmentation are much more similar than previously thought. In Tribolium, Cad has been proposed to modulate the frequency of the segmentation oscillator. Surprisingly, our simulations and experiments show that the shift rate of posterior gap domains is independent of maternal Cad levels in Drosophila. Our results suggest a novel evolutionary scenario for the short- to long-germband transition and help explain why this transition occurred convergently multiple times during the radiation of the holometabolan insects. PMID- 29451885 TI - Repeated stimulation, inter-stimulus interval and inter-electrode distance alters muscle contractile properties as measured by Tensiomyography. AB - CONTEXT: The influence of methodological parameters on the measurement of muscle contractile properties using Tensiomyography (TMG) has not been published. OBJECTIVE: To investigate the; (1) reliability of stimulus amplitude needed to elicit maximum muscle displacement (Dm), (2) effect of changing inter-stimulus interval on Dm (using a fixed stimulus amplitude) and contraction time (Tc), (3) the effect of changing inter-electrode distance on Dm and Tc. DESIGN: Within subject, repeated measures. PARTICIPANTS: 10 participants for each objective. MAIN OUTCOME MEASURES: Dm and Tc of the rectus femoris, measured using TMG. RESULTS: The coefficient of variance (CV) and the intra-class correlation (ICC) of stimulus amplitude needed to elicit maximum Dm was 5.7% and 0.92 respectively. Dm was higher when using an inter-electrode distance of 7cm compared to 5cm [P = 0.03] and when using an inter-stimulus interval of 10s compared to 30s [P = 0.017]. Further analysis of inter-stimulus interval data, found that during 10 repeated stimuli Tc became faster after the 5th measure when compared to the second measure [P<0.05]. The 30s inter-stimulus interval produced the most stable Tc over 10 measures compared to 10s and 5s respectively. CONCLUSION: Our data suggest that the stimulus amplitude producing maximum Dm of the rectus femoris is reliable. Inter-electrode distance and inter-stimulus interval can significantly influence Dm and/ or Tc. Our results support the use of a 30s inter-stimulus interval over 10s or 5s. Future studies should determine the influence of methodological parameters on muscle contractile properties in a range of muscles. PMID- 29451886 TI - Which preferences associate with school performance?-Lessons from an exploratory study with university students. AB - Success in life is determined to a large extent by school performance so it is important to understand the effect of the factors that influence it. In this exploratory study, in addition to cognitive abilities, we attempt to link measures of preferences with outcomes of school performance. We measured in an incentivized way risk, time, social and competitive preferences and cognitive abilities of university students to look for associations between these measures and two important academic outcome measures: exam results and GPA. We find consistently that cognitive abilities (proxied by the Cognitive Reflection Test) are very well correlated with school performance. Regarding non-cognitive skills, we report suggestive evidence for many of our measured preferences. We used two alternative measures of time preference: patience and present bias. Present bias explains exam grades better, while patience explains GPA relatively better. Both measures of time preferences have a non-linear relation to school performance. Competitiveness matters, as students, who opt for a more competitive payment scheme in our experimental task have a higher average GPA. We observe also that risk-averse students perform a little better than more risk-tolerant students. That makes sense in case of multiple choice exams, because more risk-tolerant students may want to try to pass the exam less prepared, as the possibility of passing an exam just by chance is not zero. Finally, we have also detected that cooperative preferences-the amount of money offered in a public good game associates strongly with GPA in a non-linear way. Students who offered around half of their possible amounts had significantly higher GPAs than those, who offered none or all their money. PMID- 29451888 TI - Ecogeography of teosinte. AB - Adaptation of crops to climate change has motivated an increasing interest in the potential value of novel traits from wild species; maize wild relatives, the teosintes, harbor traits that may be useful to maize breeding. To study the ecogeographic distribution of teosinte we constructed a robust database of 2363 teosinte occurrences from published sources for the period 1842-2016. A geographical information system integrating 216 environmental variables was created for Mexico and Central America and was used to characterize the environment of each teosinte occurrence site. The natural geographic distribution of teosinte extends from the Western Sierra Madre of the State of Chihuahua, Mexico to the Pacific coast of Nicaragua and Costa Rica, including practically the entire western part of Mesoamerica. The Mexican annuals Zea mays ssp. parviglumis and Zea mays ssp. mexicana show a wide distribution in Mexico, while Zea diploperennis, Zea luxurians, Zea perennis, Zea mays ssp. huehuetenangensis, Zea vespertilio and Zea nicaraguensis had more restricted and distinct ranges, representing less than 20% of the total occurrences. Only 11.2% of teosinte populations are found in Protected Natural Areas in Mexico and Central America. Ecogeographical analysis showed that teosinte can cope with extreme levels of precipitation and temperatures during growing season. Modelling teosinte geographic distribution demonstrated congruence between actual and potential distributions; however, some areas with no occurrences appear to be within the range of adaptation of teosintes. Field surveys should be prioritized to such regions to accelerate the discovery of unknown populations. Potential areas for teosintes Zea mays ssp. mexicana races Chalco, Nobogame, and Durango, Zea mays ssp. huehuetenangensis, Zea luxurians, Zea diploperennis and Zea nicaraguensis are geographically separated; however, partial overlapping occurs between Zea mays ssp. parviglumis and Zea perennis, between Zea mays ssp. parviglumis and Zea diploperennis, and between Zea mays ssp. mexicana race Chalco and Zea mays ssp. mexicana race Central Plateau. Assessing priority of collecting for conservation showed that permanent monitoring programs and in-situ conservation projects with participation of local farmer communities are critically needed; Zea mays ssp. mexicana (races Durango and Nobogame), Zea luxurians, Zea diploperennis, Zea perennis and Zea vespertilio should be considered as the highest priority taxa. PMID- 29451887 TI - Evaluating diagnostic indicators of urogenital Schistosoma haematobium infection in young women: A cross sectional study in rural South Africa. AB - BACKGROUND: Urine microscopy is the standard diagnostic method for urogenital S. haematobium infection. However, this may lead to under-diagnosis of urogenital schistosomiasis, as the disease may present itself with genital symptoms in the absence of ova in the urine. Currently there is no single reliable and affordable diagnostic method to diagnose the full spectrum of urogenital S. haematobium infection. In this study we explore the classic indicators in the diagnosis of urogenital S. haematobium infection, with focus on young women. METHODS: In a cross-sectional study of 1237 sexually active young women in rural South Africa, we assessed four diagnostic indicators of urogenital S. haematobium infection: microscopy of urine, polymerase chain reaction (PCR) of cervicovaginal lavage (CVL), urogenital symptoms, and sandy patches detected clinically in combination with computerised image analysis of photocolposcopic images. We estimated the accuracy of these diagnostic indicators through the following analyses: 1) cross tabulation (assumed empirical gold standard) of the tests against the combined findings of sandy patches and/or computerized image analysis and 2) a latent class model of the four indicators without assuming any gold standard. RESULTS: The empirical approach showed that urine microscopy had a sensitivity of 34.7% and specificity of 75.2% while the latent class analysis approach (LCA) suggested a sensitivity of 81.0% and specificity of 85.6%. The empirical approach and LCA showed that Schistosoma PCR in CVL had low sensitivity (14.1% and 52.4%, respectively) and high specificity (93.0% and 98.0, respectively). Using LCA, the presence of sandy patches showed a sensitivity of 81.6 and specificity of 42.4%. The empirical approach and LCA showed that urogenital symptoms had a high sensitivity (89.4% and 100.0%, respectively), whereas specificity was low (10.6% and 12.3%, respectively). CONCLUSION: All the diagnostic indicators used in the study had limited accuracy. Using urine microscopy or Schistosoma PCR in CVL would only confirm a fraction of the sandy patches found by colposcopic examination. PMID- 29451890 TI - Detection of Bartonella spp. in fleas by MALDI-TOF MS. AB - BACKGROUND: Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (MALDI-TOF MS) has recently emerged in the field of entomology as a promising method for the identification of arthropods and the detection of associated pathogens. METHODOLOGY/PRINCIPAL FINDINGS: An experimental model of Ctenocephalides felis (cat fleas) infected with Bartonella quintana and Bartonella henselae was developed to evaluate the efficacy of MALDI-TOF MS in distinguishing infected from uninfected fleas, and its ability to distinguish fleas infected with Bartonella quintana from fleas infected with Bartonella henselae. For B. quintana, two groups of fleas received three successive blood meals, infected or not. A total of 140 fleas (100 exposed fleas and 40 control fleas) were engorged on human blood, infected or uninfected with B. quintana. Regarding the second pathogen, two groups of fleas (200 exposed fleas and 40 control fleas) were fed in the same manner with human blood, infected or not with Bartonella henselae. Fleas were dissected longitudinally; one-half was used for assessment of B. quintana and B. henselae infectious status by real-time PCR, and the second half was subjected to MALDI-TOF MS analysis. Comparison of MS spectra from infected fleas and uninfected fleas revealed distinct MS profiles. Blind queries against our MALDI-TOF MS arthropod database, upgraded with reference spectra from B. quintana and B. henselae infected fleas but also non-infected fleas, provided the correct classification for 100% of the different categories of specimens tested on the first model of flea infection with Bartonella quintana. As for Bartonella henselae, 81% of exposed qPCR-positive fleas, 96% of exposed qPCR-negative fleas and 100% of control fleas were correctly identified on the second model of flea infection. MALDI-TOF MS successfully differentiated Bartonella spp.-infected and uninfected fleas and was also able to correctly differentiate fleas infected with Bartonella quintana and fleas infected with Bartonella henselae. MALDI-TOF MS correctly identified flea species as well as their infectious status, consistent with the results of real-time PCR. CONCLUSIONS/SIGNIFICANCE: MALDI-TOF is a promising tool for identification of the infection status of fleas infected with Bartonella spp., which allows new possibilities for fast and accurate diagnosis in medical entomology and vector surveillance.

AB - Spinal plasticity is thought to contribute to sensorimotor recovery of limb function in several neurological disorders and can be experimentally induced in animals and humans using different stimulation protocols. In healthy individuals, electrical continuous Theta Burst Stimulation (TBS) of the median nerve has been shown to change spinal motoneuron excitability in the cervical spinal cord as indexed by a change in mean H-reflex amplitude in the flexor carpi radialis muscle. It is unknown whether continuous TBS of a peripheral nerve can also shift motoneuron excitability in the lower limb. In 26 healthy subjects, we examined the effects of electrical TBS given to the tibial nerve in the popliteal fossa on the excitability of lumbar spinal motoneurons as measured by H-reflex amplitude of the soleus muscle evoked by tibial nerve stimulation. Continuous TBS was given at 110% of H-reflex threshold intensity and compared to non-patterned regular electrical stimulation at 15 Hz. To disclose any pain-induced effects, we also tested the effects of TBS at individual sensory threshold. Moreover, in a subgroup of subjects we evaluated paired-pulse inhibition of H-reflex. Continuous TBS at 110% of H-reflex threshold intensity induced a short-term reduction of H reflex amplitude. The other stimulation conditions produced no after effects. Paired-pulse H-reflex inhibition was not modulated by continuous TBS or non patterned repetitive stimulation at 15 Hz. An effect of pain on the results obtained was discarded, since non-patterned 15 Hz stimulation at 110% HT led to pain scores similar to those induced by EcTBS at 110% HT, but was not able to induce any modulation of the H reflex amplitude. Together, the results provide first time evidence that peripheral continuous TBS induces a short-lasting change in the excitability of spinal motoneurons in lower limb circuitries. Future studies need to investigate how the TBS protocol can be optimized to produce a larger and longer effect on spinal cord physiology and whether this might be a useful intervention in patients with excessive excitability of the spinal motorneurons. PMID- 29451892 TI - Assessing site formation and assemblage integrity through stone tool refitting at Gruta da Oliveira (Almonda karst system, Torres Novas, Portugal): A Middle Paleolithic case study. AB - We use stone tool refitting to assess palimpsest formation and stratigraphic integrity in the basal units of the Gruta da Oliveira archeo-stratigraphic sequence, layers 15-27, which TL and U-series dating places in late Marine Isotope Stage (MIS) 5 or early MIS 4. As in most karst contexts, the formation of this succession involved multiple and complex phenomena, including subsidence, bioturbation, carnivore activity and runoff as agents of potential post depositional disturbance. During phases of stabilization, such as represented by layers 15, 21 and 22, the excavated area was inhabited and refits corroborate that post-depositional displacement is negligible. Layers 23-25 and 16-19 correspond to subdivisions that slice thick geological units primarily formed of material derived from the cave's entrance via slope dynamics. Refit links are consistent with rapid fill-up of the interstitial spaces found in the Karren-like bedrock (for layers 23-25), or left between large boulders after major roof collapse events (for layers 16-19). Layers 26 (the "Mousterian Cone") and 27 are a "bottom-of-hourglass" deposit underlying the main sedimentary body; the refits show that this deposit consists of material derived from layers 15-25 that gravitated through fissures open in the sedimentary column above. Layer 20, at the interface between two major stratigraphic ensembles, requires additional analysis. Throughout, we found significant vertical dispersion along the contact between sedimentary fill and cave wall. Given these findings, a preliminary analysis of technological change across the studied sequence organized the lithic assemblages into five ensembles: layer 15; layers 16-19; layer 20; layers 21-22; layers 23-25. The lower ensembles show higher percentages of flint and of the Levallois method. Uniquely at the site, the two upper ensembles feature bifaces and cleavers. PMID- 29451891 TI - Association of an intact E2 gene with higher HPV viral load, higher viral oncogene expression, and improved clinical outcome in HPV16 positive head and neck squamous cell carcinoma. AB - To assess the relationship of E2 gene disruption with viral gene expression and clinical outcome in human papillomavirus (HPV) positive head and neck squamous cell carcinoma, we evaluated 31 oropharyngeal and 17 non-oropharyngeal HPV16 positive carcinomas using two PCR-based methods to test for disruption of E2, followed by Sanger sequencing. Expression of HPV16 E6, E7 and E2 transcripts, along with cellular ARF and INK4A, were also assessed by RT-qPCR. Associations between E2 disruption, E2/E6/E7 expression, and clinical outcome were evaluated by Kaplan-Meier analysis for loco-regional recurrence and disease-specific survival. The majority (n = 21, 68%) of HPV16 positive oropharyngeal carcinomas had an intact E2 gene, whereas the majority of HPV16 positive non-oropharyngeal carcinomas (n = 10, 59%) had a disrupted E2 gene. Three of the oropharyngeal tumors and two of the non-oropharyngeal tumors had deletions within E2. Detection of an intact E2 gene was associated with a higher DNA viral load and increased E2/E6/E7, ARF and INK4A expression in oropharyngeal tumors. Oropharyngeal carcinomas with an intact E2 had a lower risk of loco-regional recurrence (log rank p = 0.04) and improved disease-specific survival (p = 0.03) compared to tumors with disrupted E2. In addition, high E7 expression was associated with lower risk of loco-regional recurrence (p = 0.004) as was high E6 expression (p = 0.006). In summary, an intact E2 gene is more common in HPV16 positive oropharyngeal than non-oropharyngeal carcinomas; the presence of an intact E2 gene is associated with higher HPV viral load, higher viral oncogene expression, and improved clinical outcome compared to patients with a disrupted E2 gene in oropharyngeal cancer. PMID- 29451893 TI - Vegetative compatibility groups partition variation in the virulence of Verticillium dahliae on strawberry. AB - Verticillium dahliae infection of strawberry (Fragaria x ananassa) is a major cause of disease-induced wilting in soil-grown strawberries across the world. To understand what components of the pathogen are affecting disease expression, the presence of the known effector VdAve1 was screened in a sample of Verticillium dahliae isolates. Isolates from strawberry were found to contain VdAve1 and were divided into two major clades, based upon their vegetative compatibility groups (VCG); no UK strawberry isolates contained VdAve1. VC clade was strongly related to their virulence levels. VdAve1-containing isolates pathogenic on strawberry were found in both clades, in contrast to some recently published findings. On strawberry, VdAve1-containing isolates had significantly higher virulence during early infection, which diminished in significance as the infection progressed. Transformation of a virulent non-VdAve1 containing isolate, with VdAve1 was found neither to increase nor decrease virulence when inoculated on a susceptible strawberry cultivar. There are therefore virulence factors that are epistatic to VdAve1 and potentially multiple independent routes to high virulence on strawberry in V. dahliae lineages. Genome sequencing a subset of isolates across the two VCGs revealed that isolates were differentiated at the whole genome level and contained multiple changes in putative effector content, indicating that different clonal VCGs may have evolved different strategies for infecting strawberry, leading to different virulence levels in pathogenicity tests. It is therefore important to consider both clonal lineage and effector complement as the adaptive potential of each lineage will differ, even if they contain the same race determining effector. PMID- 29451894 TI - Trade-off between synergy and efficacy in combinations of HIV-1 latency-reversing agents. AB - Eradicating HIV-1 infection is difficult because of the reservoir of latently infected cells that gets established soon after infection, remains hidden from antiretroviral drugs and host immune responses, and retains the capacity to reignite infection following the cessation of treatment. Drugs called latency reversing agents (LRAs) are being developed to reactivate latently infected cells and render them susceptible to viral cytopathicity or immune killing. Whereas individual LRAs have failed to induce adequate reactivation, pairs of LRAs have been identified recently that act synergistically and hugely increase reactivation levels compared to individual LRAs. The maximum synergy achievable with LRA pairs is of clinical importance, as it would allow latency-reversal with minimal drug exposure. Here, we employed stochastic simulations of HIV-1 transcription and translation in latently infected cells to estimate this maximum synergy. We incorporated the predominant mechanisms of action of the two most promising classes of LRAs, namely, protein kinase C agonists and histone deacetylase inhibitors, and quantified the activity of individual LRAs in the two classes by mapping our simulations to corresponding in vitro experiments. Without any adjustable parameters, our simulations then quantitatively captured experimental observations of latency-reversal when the LRAs were used in pairs. Performing simulations representing a wide range of drug concentrations, we estimated the maximum synergy achievable with these LRA pairs. Importantly, we found with all the LRA pairs we considered that concentrations yielding the maximum synergy did not yield the maximum latency-reversal. Increasing concentrations to increase latency-reversal compromised synergy, unravelling a trade-off between synergy and efficacy in LRA combinations. The maximum synergy realizable with LRA pairs would thus be restricted by the desired level of latency-reversal, a constrained optimum we elucidated with our simulations. We expect this trade-off to be important in defining optimal LRA combinations that would maximize synergy while ensuring adequate latency-reversal. PMID- 29451895 TI - Metabolic enzyme cost explains variable trade-offs between microbial growth rate and yield. AB - Microbes may maximize the number of daughter cells per time or per amount of nutrients consumed. These two strategies correspond, respectively, to the use of enzyme-efficient or substrate-efficient metabolic pathways. In reality, fast growth is often associated with wasteful, yield-inefficient metabolism, and a general thermodynamic trade-off between growth rate and biomass yield has been proposed to explain this. We studied growth rate/yield trade-offs by using a novel modeling framework, Enzyme-Flux Cost Minimization (EFCM) and by assuming that the growth rate depends directly on the enzyme investment per rate of biomass production. In a comprehensive mathematical model of core metabolism in E. coli, we screened all elementary flux modes leading to cell synthesis, characterized them by the growth rates and yields they provide, and studied the shape of the resulting rate/yield Pareto front. By varying the model parameters, we found that the rate/yield trade-off is not universal, but depends on metabolic kinetics and environmental conditions. A prominent trade-off emerges under oxygen limited growth, where yield-inefficient pathways support a 2-to-3 times higher growth rate than yield-efficient pathways. EFCM can be widely used to predict optimal metabolic states and growth rates under varying nutrient levels, perturbations of enzyme parameters, and single or multiple gene knockouts. PMID- 29451897 TI - Selective identification of somatic mutations in pancreatic cancer cells through a combination of next-generation sequencing of plasma DNA using molecular barcodes and a bioinformatic variant filter. AB - The accuracy of next-generation sequencing (NGS) for detecting tumor-specific mutations in plasma DNA is hindered by errors introduced during PCR/sequencing, base substitutions caused by DNA damage, and pre-existing mutations in normal cells that are present at a low frequency. Here, we performed NGS of genes related to pancreatic cancer (comprising 2.8 kb of genomic DNA) in plasma DNA (average 4.5 ng) using molecular barcodes. The average number of sequenced molecules was 900, and the sequencing depth per molecule was 100 or more. We also developed a bioinformatic variant filter, called CV78, to remove variants that were not considered to be tumor-specific, i.e., those that are either absent or occur at low frequencies in the Catalogue of Somatic Mutations in Cancer database. In a cohort comprising 57 pancreatic cancer patients and 12 healthy individuals, sequencing initially identified variants in 31 (54%) and 5 (42%), respectively, whereas after applying the CV78 filter, 19 (33%) and zero were variant-positive. In a validation cohort consisting of 86 patients with pancreatic cancer and 20 patients with intraductal papillary mucinous neoplasm (IPMN), 62 (72%) with pancreatic cancer patients and 10 (50%) IPMN patients were initially variant positive. After CV78 filtering, these values were reduced to 32 (37%) and 1 (5%), respectively. The variant allele frequency of filtered variants in plasma ranged from 0.25% to 76.1%. Therefore, combining NGS and molecular barcodes with subsequent filtering is likely to eliminate most non-tumor-specific mutations. PMID- 29451896 TI - Hypomyelinating disorders in China: The clinical and genetic heterogeneity in 119 patients. AB - OBJECTIVE: Hypomyelinating disorders are a group of clinically and genetically heterogeneous diseases characterized by neurological deterioration with hypomyelination visible on brain MRI scans. This study was aimed to clarify the clinical and genetic features of HMDs in Chinese population. METHODS: 119 patients with hypomyelinating disorders in Chinese population were enrolled and evaluated based on their history, clinical manifestation, laboratory examinations, series of brain MRI with follow-up, genetic etiological tests including chromosomal analysis, multiplex ligation probe amplification, Sanger sequencing, targeted enrichment-based next-generation sequencing and whole exome sequencing. RESULTS: Clinical and genetic features of hypomyelinating disorders were revealed. Nine different hypomyelinating disorders were identified in 119 patients: Pelizaeus-Merzbacher disease (94, 79%), Pelizaeus-Merzbacher-like disease (10, 8%), hypomyelination with atrophy of the basal ganglia and cerebellum (3, 3%), GM1 gangliosidosis (5, 4%), GM2 gangliosidosis (3, 3%), trichothiodystrophy (1, 1%), Pol III-related leukodystrophy (1, 1%), hypomyelinating leukodystrophy type 9 (1, 1%), and chromosome 18q deletion syndrome (1, 1%). Of the sample, 94% (112/119) of the patients were genetically diagnosed, including 111 with mutations distributing across 9 genes including PLP1, GJC2, TUBB4A, GLB1, HEXA, HEXB, ERCC2, POLR3A, and RARS and 1 with mosaic chromosomal change of 46, XX,del(18)(q21.3)/46,XX,r(18)(p11.32q21.3)/45,XX,-18. Eighteen novel mutations were discovered. Mutations in POLR3A and RARS were first identified in Chinese patients with Pol III-related leukodystrophy and hypomyelinating leukodystrophy, respectively. SIGNIFICANCE: This is the first report on clinical and genetic features of hypomyelinating disorders with a large sample of patients in Chinese population, identifying 18 novel mutations especially mutations in POLR3A and RARS in Chinese patients, expanding clinical and genetic spectrums of hypomyelinating disorders. PMID- 29451898 TI - Integrating linear optimization with structural modeling to increase HIV neutralization breadth. AB - Computational protein design has been successful in modeling fixed backbone proteins in a single conformation. However, when modeling large ensembles of flexible proteins, current methods in protein design have been insufficient. Large barriers in the energy landscape are difficult to traverse while redesigning a protein sequence, and as a result current design methods only sample a fraction of available sequence space. We propose a new computational approach that combines traditional structure-based modeling using the Rosetta software suite with machine learning and integer linear programming to overcome limitations in the Rosetta sampling methods. We demonstrate the effectiveness of this method, which we call BROAD, by benchmarking the performance on increasing predicted breadth of anti-HIV antibodies. We use this novel method to increase predicted breadth of naturally-occurring antibody VRC23 against a panel of 180 divergent HIV viral strains and achieve 100% predicted binding against the panel. In addition, we compare the performance of this method to state-of-the-art multistate design in Rosetta and show that we can outperform the existing method significantly. We further demonstrate that sequences recovered by this method recover known binding motifs of broadly neutralizing anti-HIV antibodies. Finally, our approach is general and can be extended easily to other protein systems. Although our modeled antibodies were not tested in vitro, we predict that these variants would have greatly increased breadth compared to the wild type antibody. PMID- 29451899 TI - Cooperation enhanced by the coevolution of teaching activity in evolutionary prisoner's dilemma games with voluntary participation. AB - Voluntary participation, as an additional strategy involved in repeated games, has been proved to be an efficient way to promote the evolution of cooperation theoretically and empirically. Besides, current studies show that the coevolution of teaching activity can promote cooperation. Thus, inspired by aforementioned above, we investigate the effect of coevolution of teaching activity on the evolution of cooperation for prisoner's dilemma game with voluntary participation: when the focal player successfully enforces its strategy on the opponent, his teaching ability will get an increase. Through numerical simulation, we have shown that voluntary participation could effectively promote the fraction of cooperation, which is also affected by the value of increment. Furthermore, we investigate the influence of the increment value on the density of different strategies and find that there exists an optimal increment value that plays an utmost role on the evolutionary dynamics. With regard to this observation, we unveil that an optimal value of increment can lead to strongest heterogeneity in agents' teaching ability, further promoting the evolution of cooperation. PMID- 29451900 TI - The ARID1A, p53 and beta-Catenin statuses are strong prognosticators in clear cell and endometrioid carcinoma of the ovary and the endometrium. AB - AIM: The objective of this study was to evaluate the prognostic value of ARID1A, p53, p21, p16 and beta-Catenin in endometrioid and clear cell ovarian and endometrial carcinomas. MATERIALS AND METHODS: 97 tumors were available for analysis of ARID1A, p53, p21, p16 and beta-Catenin with the techniques of tissue microarray and immunohistochemistry. 32 were ovarian carcinomas and 65 were endometrial carcinomas. RESULTS: Endometrioid ovarian carcinomas showed negative staining for ARID1A (a) and p21 (b), aberrant expression of p53 (c) and p16 (d) and beta-Catenin positive nuclear expression (e) respectively in 19% (a), 100% (b), 28.6% (c), 52.4% (d) and 4.8% (e) of all cases. In the group of clear cell ovarian carcinomas it was 63.6% (a), 100% (b), 81.8% (c), 54.5% (d) and 0% (e). For endometrioid uterine carcinomas it was 75.7% (a), 94.9% (b), 30.5% (c), 52.1% (d) and 6.8% (e) and for clear cell uterine carcinomas it was 8.6% (a), 100% (b), 50% (c), 100% (d) and 0% (e). Survival analysis showed that negative expression of ARID1A, p53 aberrant expression and beta-Catenin nuclear positive staining are independent negative prognosticators in both, clear cell and endometrioid carcinoma, regardless of ovarian or uterine origin. Cox-Regression analysis showed them again as negative prognostic factors. Furthermore, we found a significant correlation between ARID1A and beta-Catenin expression in endometrioid uterine tumors. CONCLUSION: The analyzed gynaecological carcinoma showed a distinct expression scheme of proteins that are associated with tumor suppression. We may conclude that ARID1A, p53 and beta-Catenin are the strongest prognostic factors by analyzing a subgroup of tumor suppressor genes in clear cell and endometrioid subtypes of ovarian and endometrial cancer and may be used along with traditional morphological and clinical characteristics for prognosis. PMID- 29451901 TI - The novel antibiotic rhodomyrtone traps membrane proteins in vesicles with increased fluidity. AB - The acylphloroglucinol rhodomyrtone is a promising new antibiotic isolated from the rose myrtle Rhodomyrtus tomentosa, a plant used in Asian traditional medicine. While many studies have demonstrated its antibacterial potential in a variety of clinical applications, very little is known about the mechanism of action of rhodomyrtone. Preceding studies have been focused on intracellular targets, but no specific intracellular protein could be confirmed as main target. Using live cell, high-resolution, and electron microscopy we demonstrate that rhodomyrtone causes large membrane invaginations with a dramatic increase in fluidity, which attract a broad range of membrane proteins. Invaginations then form intracellular vesicles, thereby trapping these proteins. Aberrant protein localization impairs several cellular functions, including the respiratory chain and the ATP synthase complex. Being uncharged and devoid of a particular amphipathic structure, rhodomyrtone did not seem to be a typical membrane inserting molecule. In fact, molecular dynamics simulations showed that instead of inserting into the bilayer, rhodomyrtone transiently binds to phospholipid head groups and causes distortion of lipid packing, providing explanations for membrane fluidization and induction of membrane curvature. Both its transient binding mode and its ability to form protein-trapping membrane vesicles are unique, making it an attractive new antibiotic candidate with a novel mechanism of action. PMID- 29451902 TI - An artificial miRNA system reveals that relative contribution of translational inhibition to miRNA-mediated regulation depends on environmental and developmental factors in Arabidopsis thaliana. AB - Development and fitness of any organism rely on properly controlled gene expression. This is especially true for plants, as their development is determined by both internal and external cues. MicroRNAs (miRNAs) are embedded in the genetic cascades that integrate and translate those cues into developmental programs. miRNAs negatively regulate their target genes mainly post transcriptionally through two co-existing mechanisms; mRNA cleavage and translational inhibition. Despite our increasing knowledge about the genetic and biochemical processes involved in those concurrent mechanisms, little is known about their relative contributions to the overall miRNA-mediated regulation. Here we show that co-existence of cleavage and translational inhibition is dependent on growth temperature and developmental stage. We found that efficiency of an artificial miRNA-mediated (amiRNA) gene silencing declines with age during vegetative development in a temperature-dependent manner. That decline is mainly due to a reduction on the contribution from translational inhibition. Both, temperature and developmental stage were also found to affect mature amiRNA accumulation and the expression patterns of the core players involved in miRNA biogenesis and action. Therefore, that suggests that each miRNA family specifically regulates their respective targets, while temperature and growth might influence the performance of miRNA-dependent regulation in a more general way. PMID- 29451903 TI - Stability lies in flowers: Plant diversification mediating shifts in arthropod food webs. AB - Arthropod community composition in agricultural landscapes is dependent on habitat characteristics, such as plant composition, landscape homogeneity and the presence of key resources, which are usually absent in monocultures. Manipulating agroecosystems through the insertion of in-field floral resources is a useful technique to reduce the deleterious effects of habitat simplification. Food web analysis can clarify how the community reacts to the presence of floral resources which favour ecosystem services such as biological control of pest species. Here, we reported quantitative and qualitative alterations in arthropod food web complexity due to the presence of floral resources from the Mexican marigold (Tagetes erecta L.) in a field scale lettuce community network. The presence of marigold flowers in the field successfully increased richness, body size, and the numerical and biomass abundance of natural enemies in the lettuce arthropod community, which affected the number of links, vulnerability, generality, omnivory rate and food chain length in the community, which are key factors for the stability of relationships between species. Our results reinforce the notion that diversification through insertion of floral resources may assist in preventing pest outbreaks in agroecosystems. This community approach to arthropod interactions in agricultural landscapes can be used in the future to predict the effect of different management practices in the food web to contribute with a more sustainable management of arthropod pest species. PMID- 29451904 TI - Phytoforensics: Trees as bioindicators of potential indoor exposure via vapor intrusion. AB - Human exposure to volatile organic compounds (VOCs) via vapor intrusion (VI) is an emerging public health concern with notable detrimental impacts on public health. Phytoforensics, plant sampling to semi-quantitatively delineate subsurface contamination, provides a potential non-invasive screening approach to detect VI potential, and plant sampling is effective and also time- and cost efficient. Existing VI assessment methods are time- and resource-intensive, invasive, and require access into residential and commercial buildings to drill holes through basement slabs to install sampling ports or require substantial equipment to install groundwater or soil vapor sampling outside the home. Tree core samples collected in 2 days at the PCE Southeast Contamination Site in York, Nebraska were analyzed for tetrachloroethene (PCE) and results demonstrated positive correlations with groundwater, soil, soil-gas, sub-slab, and indoor-air samples collected over a 2-year period. Because tree-core samples were not collocated with other samples, interpolated surfaces of PCE concentrations were estimated so that comparisons could be made between pairs of data. Results indicate moderate to high correlation with average indoor-air and sub-slab PCE concentrations over long periods of time (months to years) to an interpolated tree-core PCE concentration surface, with Spearman's correlation coefficients (rho) ranging from 0.31 to 0.53 that are comparable to the pairwise correlation between sub-slab and indoor-air PCE concentrations (rho = 0.55, n = 89). Strong correlations between soil-gas, sub-slab, and indoor-air PCE concentrations and an interpolated tree-core PCE concentration surface indicate that trees are valid indicators of potential VI and human exposure to subsurface environment pollutants. The rapid and non-invasive nature of tree sampling are notable advantages: even with less than 60 trees in the vicinity of the source area, roughly 12 hours of tree-core sampling with minimal equipment at the PCE Southeast Contamination Site was sufficient to delineate vapor intrusion potential in the study area and offered comparable delineation to traditional sub slab sampling performed at 140 properties over a period of approximately 2 years. PMID- 29451905 TI - Otoacoustic emissions from ears with spontaneous activity behave differently to those without: Stronger responses to tone bursts as well as to clicks. AB - It has been reported that both click-evoked otoacoustic emissions (CEOAEs) and distortion product otoacoustic emissions (DPOAEs) have higher amplitudes in ears that possess spontaneous otoacoustic emissions (SOAEs). The general aim of the present study was to investigate whether the presence of spontaneous activity in the cochlea affected tone-burst evoked otoacoustic emissions (TBOAEs). As a benchmark, the study also measured growth functions of CEOAEs. Spontaneous activity in the cochlea was measured by the level of synchronized spontaneous otoacoustic emissions (SSOAEs), an emission evoked by a click but closely related to spontaneous otoacoustic emissions (SOAEs, which are detectable without any stimulus). Measurements were made on a group of 15 adults whose ears were categorized as either having recordable SSOAEs or no SSOAEs. In each ear, CEOAEs and TBOAEs were registered at frequencies of 0.5, 1, 2, and 4 kHz, and input/output functions were measured at 40, 50, 60, 70, and 80 dB SPL. Global and half-octave-band values of response level and latency were estimated. Our main finding was that in ears with spontaneous activity, TBOAEs had higher levels than in ears without. The difference was more apparent for global values, but were also seen with half-octave-band analysis. Input/output functions had similar growth rates for ears with and without SSOAEs. There were no significant differences in latencies between TBOAEs from ears with and without SSOAEs, although latencies tended to be longer for lower stimulus levels and lower stimulus frequencies. When TBOAE levels were compared to CEOAE levels, the latter showed greater differences between recordings from ears with and without SSOAEs. Although TBOAEs reflect activity from a more restricted cochlear region than CEOAEs, at all stimulus frequencies their behavior still depends on whether SSOAEs are present or not. PMID- 29451907 TI - Timber isoscapes. A case study in a mountain area in the Italian Alps. AB - BACKGROUND: Local timber is still one of the main sources of work and income for mountain communities. However, illegal logging is a major cause of deforestation in many countries and has significant impacts on local communities and biodiversity. Techniques for tracing timber would provide a useful tool to protect local timber industries and contribute to the fight against illegal logging. Although considerable progress has been made in food traceability, timber provenance is still a somewhat neglected research area. Stable isotope ratios in plants are known to reflect geographical variations. This study reports accurate spatial distribution of delta18O and delta2H in timber from north eastern Italy (Trentino) in order to trace geographical origin. METHODOLOGY AND PRINCIPAL FINDINGS: We tested the accuracy of four kriging methods using an annual resolution of delta18O and delta2H measured in Picea abies. Pearson's correlation coefficients revealed altitude to be the most appropriate covariate for the cokriging model, which has ultimately proved to be the best method due to its low estimation error. CONCLUSIONS: We present regional maps of interpolated delta18O and delta2H in Picea abies wood together with the 95% confidence intervals. The strong spatial structure of the data demonstrates the potential of multivariate spatial interpolation, even in a highly heterogeneous area such as the Alps. We believe that this geospatial approach can be successfully applied on a wider scale in order to combat illegal logging. PMID- 29451906 TI - Brain changes due to hypoxia during light anaesthesia can be prevented by deepening anaesthesia; a study in rats. AB - In anaesthetic practice the risk of cerebral ischemic/hypoxic damage is thought to be attenuated by deep anaesthesia. The rationale is that deeper anaesthesia reduces cerebral oxygen demand more than light anaesthesia, thereby increasing the tolerance to ischemia or hypoxia. However, evidence to support this is scarce. We thus investigated the influence of light versus deep anaesthesia on the responses of rat brains to a period of hypoxia. In the first experiment we exposed adult male Wistar rats to deep or light propofol anaesthesia and then performed [18F]- Fludeoxyglucose (FDG) Positron Emission Tomography (PET) scans to verify the extent of cerebral metabolic suppression. In subsequent experiments, rats were subjected to light/deep propofol anaesthesia and then exposed to a period of hypoxia or ongoing normoxia (n = 9-11 per group). A further 5 rats, not exposed to anaesthesia or hypoxia, served as controls. Four days later a Novel Object Recognition (NOR) test was performed to assess mood and cognition. After another 4 days, the animals were sacrificed for later immunohistochemical analyses of neurogenesis/neuroplasticity (Doublecortin; DCX), Brain Derived Neurotrophic Factor (BDNF) expression and neuroinflammation (Ionized calcium-binding adaptor protein-1; Iba-1) in hippocampal and piriform cortex slices. The hippocampi of rats subjected to hypoxia during light anaesthesia showed lower DCX positivity, and therefore lower neurogenesis, but higher BDNF levels and microglia hyper-ramification. Exploration was reduced, but no significant effect on NOR was observed. In the piriform cortex, higher DCX positivity was observed, associated with neuroplasticity. All these effects were attenuated by deep anaesthesia. Deepening anaesthesia attenuated the brain changes associated with hypoxia. Hypoxia during light anaesthesia had a prolonged effect on the brain, but no impairment in cognitive function was observed. Although reduced hippocampal neurogenesis may be considered unfavourable, higher BDNF expression, associated with microglia hyper-ramification may suggest activation of repair mechanisms. Increased neuroplasticity observed in the piriform cortex supports this, and might reflect a prolonged state of alertness rather than damage. PMID- 29451908 TI - Cas9-mediated excision of proximal DNaseI/H3K4me3 signatures confers robust silencing of microRNA and long non-coding RNA genes. AB - CRISPR/Cas9-based approaches have greatly facilitated targeted genomic deletions. Contrary to coding genes however, which can be functionally knocked out by frame shift mutagenesis, non-coding RNA (ncRNA) gene knockouts have remained challenging. Here we present a universal ncRNA knockout approach guided by epigenetic hallmarks, which enables robust gene silencing even in provisionally annotated gene loci. We build on previous work reporting the presence of overlapping histone H3 lysine 4 tri-methylation (H3K4me3) and DNaseI hypersensitivity sites around the transcriptional start sites of most genes. We demonstrate that excision of this gene-proximal signature leads to loss of microRNA and lincRNA transcription and reveals ncRNA phenotypes. Exemplarily we demonstrate silencing of the constitutively transcribed MALAT1 lincRNA gene as well as of the inducible miR-146a and miR-155 genes in human monocytes. Our results validate a role of miR-146a and miR-155 in negative feedback control of the activity of inflammation master-regulator NFkappaB and suggest that cell cycle control is a unique feature of miR-155. We suggest that our epigenetically guided CRISPR approach may improve existing ncRNA knockout strategies and contribute to the development of high-confidence ncRNA phenotyping applications. PMID- 29451909 TI - Rapid purification of giant lipid vesicles by microfiltration. AB - Giant lipid vesicles (GVs) are emerging models for investigating the properties and reactivity of cell-like microcompartments, providing useful information about plausible protocellular structures in primitive times, as well as for the modern synthetic biology goal of constructing the first artificial cell from its reconstituted and partly modified components. Here we explore a novel methodology of GV purification by microfiltration under reduced pressure, operated by a simple apparatus. The method has been characterized in terms of flow rate, amount of lipid loss, quality of recovered GVs, and size distribution. A case study is reported to show the practicability of GV microfiltration. A clickable fluorescent probe was encapsulated inside GVs; more than 99.9% of the non entrapped probe was easily and rapidly removed by multiple microfiltrations. This novel methodology is briefly discussed as a future tool for selection experiments on GV populations.

AB - The expansion of international trade in commodities increases the risk of alien species invasions. Invaders are difficult to detect on introduction, so prevention remains the preferred strategy for managing the threat of invasions. Propagule pressure has been shown to be a good predictor of invasion risk. Most studies to date, however, link potential invasive species arrivals with indirect measures of propagule pressure such as aggregate trade volumes. This paper estimates propagule pressure using data that measure actual arrivals. Specifically, it uses inspection data that covers almost all U.S. fruit and vegetable imports from 2005-2014 to estimate a logit model of the probability of potential invasive species arrival and expected propagule frequencies for 2,240 commodity/country of origin combinations. Clear patterns in the geographic origin and commodity pathways for potential pests are identified. The average probability of arrival is low, approximately 0.03, but is two to ten times higher for some commodities, most notably herbs. We identify commodities with a high number of expected arrivals due to either a large volume of trade, high interception rates, or a combination of both. Seven of the top ten countries of origin for propagule frequency are from the Western Hemisphere and further trade liberalization within the Western Hemisphere is likely to heighten challenges to enforcement of US phytosanitary standards. Patterns in the data can help identify the commodities and countries of origin in greatest need of technical assistance and guide targeting of surveillance for the pathways of greatest phytosanitary concern.

AB - Latitude is an important factor that influences the carbon stock of Moso bamboo (Phyllostachys pubescens) forests. Accurate estimation of the carbon stock of Moso bamboo forest can contribute to sufficient evaluation of forests in carbon sequestration worldwide. Nevertheless, the effect of latitude on the carbon stock of Moso bamboo remains unclear. In this study, a field survey with 36 plots of Moso bamboo forests along a latitude gradient was conducted to investigate carbon stock. Results showed that the diameter at breast height (DBH) of Moso bamboo culms increased from 8.37 cm to 10.12 cm that well fitted by Weibull model, whereas the bamboo culm density decreased from 4722 culm ha-1 to 3400 culm ha-1 with increasing latitude. The bamboo biomass carbon decreased from 60.58 Mg C ha 1 to 48.31 Mg C ha-1 from north to south. The total carbon stock of Moso bamboo forests, which comprises soil and biomass carbon, ranged from 87.83 Mg C ha-1 to 119.5 Mg C ha-1 and linearly increased with latitude. As a fast-growing plant, Moso bamboo could be harvested amounts of 6.0 Mg C ha-1 to 7.6 Mg C ha-1 annually, which indicates a high potential of this species for carbon sequestration. Parameters obtained in this study can be used to accurately estimate the carbon stock of Moso bamboo forest to establish models of the global carbon balance.

AB - Despite of multitude investigations no reliable prognostic immunohistochemical biomarkers in GIST have been established so far with added value to predict the recurrence risk of high risk GIST besides mitotic count, primary location and size. In this study, we analyzed the prognostic relevance of eight cell cycle and apoptosis modulators and of TP53 mutations for prognosis in GIST with high risk of recurrence prior to adjuvant treatment with imatinib. In total, 400 patients with high risk for GIST recurrence were randomly assigned for adjuvant imatinib either for one or for three years following laparotomy. 320 primary tumor samples with available tumor tissue were immunohistochemically analyzed prior to treatment for the expression of cell cycle regulators and apoptosis modulators cyclin D1, p21, p16, CDK4, E2F1, MDM2, p53 and p-RB1. TP53 mutational analysis was possible in 245 cases. A high expression of CDK4 was observed in 32.8% of all cases and was associated with a favorable recurrence free survival (RFS), whereas high expression of MDM2 (12.2%) or p53 (35.3%) was associated with a shorter RFS. These results were independent from the primary KIT or PDGFRA mutation. In GISTs with higher mitotic counts was a significantly increased expression of cyclin D1, p53 and E2F1. The expression of p16 and E2F1 significantly correlated to a non gastric localization. Furthermore, we observed a significant higher expression of p21 and E2F1 in KIT mutant GISTs compared to PDGFRA mutant and wt GISTs. The overall frequency of TP53 mutations was low (n = 8; 3.5%) and could not be predicted by the immunohistochemical expression of p53. In summary, mutation analysis in TP53 plays a minor role in the subgroup of high-risk GIST before adjuvant treatment with imatinib. Strong expression of MDM2 and p53 correlated with a shorter recurrence free survival, whereas a strong expression of CDK4 correlated to a better recurrence free survival.

AB - Bacillithiol is a low molecular weight thiol found in Firmicutes that is analogous to glutathione, which is absent in these bacteria. Bacillithiol transferases catalyze the transfer of bacillithiol to various substrates. The S transferase-like (STL) superfamily contains over 30,000 putative members, including bacillithiol transferases. Proteins in this family are extremely divergent and are related by structural rather than sequence similarity, leaving it unclear if all share the same biochemical activity. Bacillus subtilis encodes eight predicted STL superfamily members, only one of which has been shown to be a bacillithiol transferase. Here we find that the seven remaining proteins show varying levels of metal dependent bacillithiol transferase activity. We have renamed the eight enzymes BstA-H. Mass spectrometry and gene expression studies revealed that all of the enzymes are produced to varying levels during growth and sporulation, with BstB and BstE being the most abundant and BstF and BstH being the least abundant. Interestingly, several bacillithiol transferases are induced in the mother cell during sporulation. A strain lacking all eight bacillithiol transferases showed normal growth in the presence of stressors that adversely affect growth of bacillithiol-deficient strains, such as paraquat and CdCl2. Thus, the STL bacillithiol transferases represent a new group of proteins that play currently unknown, but potentially significant roles in bacillithiol dependent reactions. We conclude that these enzymes are highly divergent, perhaps to cope with an equally diverse array of endogenous or exogenous toxic metabolites and oxidants. PMID- 29451915 TI - Synchronic historical patterns of species diversification in seasonal aplocheiloid killifishes of the semi-arid Brazilian Caatinga. AB - The Caatinga is the largest nucleus of seasonally dry tropical forests in South America, but little is known about the evolutionary history and biogeography of endemic organisms. Evolutionary diversification and distribution of terrestrial vertebrates endemic to the Caatinga have been explained by palaeogeographical Neogene episodes, mostly related to changes in the course of the Sao Francisco River, the largest river in the region. Our objective is to estimate the timing of divergence of two endemic groups of short-lived seasonal killifishes inhabiting all ecoregions of the Caatinga, testing the occurrence of synchronic events of spatial diversification in light of available data on regional palaeogeography. We performed independent time-calibrated phylogenetic molecular analyses for two clades of sympatric and geographically widespread seasonal killifishes endemic to the Caatinga, the Hypsolebias antenori group and the Cynolebias alpha-clade. Our results consistently indicate that species diversification took place synchronically in both groups, as well as it is contemporary to diversification of other organisms adapted to life in the semi arid Caatinga, including lizards and small mammals. Both groups originated during the Miocene, but species diversification started between the Late Miocene and Early Pliocene, when global cooling probably favoured the expansion of semi-arid areas. Synchronic diversification patterns found are chronologically related to Tertiary palaeogeographical reorganizations associated to continental drift and to Quaternary climatic changes, corroborating the recent proposal that South American biodiversity has been continuously shaped between the Late Paleogene and Pleistocene. PMID- 29451916 TI - Awareness and attitude of the public toward personalized medicine in Korea. AB - OBJECTIVES: As personalized medicine (PM) is expected to greatly improve health outcomes, efforts have recently been made for its clinical implementation in Korea. We aimed to evaluate public awareness and attitude regarding PM. METHODS: We performed a self-administered questionnaire survey to 703 adults, who participated in the survey on a voluntary basis. The primary outcome measures included public knowledge, attitude, and acceptance of PM. We conducted multinomial multivariate logistic analysis for outcome variables with three response categories and performed multivariate logistic regression analyses for dichotomous outcome variables. RESULTS: Only 28% of participants had knowledge that genetic factors can contribute to inter-individual variations in drug response and the definition of PM (199 out of 702). Higher family income was correlated with greater knowledge concerning PM (OR = 3.76, p = 0.034). A majority of respondents preferred integrated pharmacogenomic testing over drug specific testing and agreed to inclusion of pharmacogenomic testing in the national health examination (64% and 77%, respectively), but only 51% were willing to pay for it. DISCUSSION: Our results identify the urgent need for public education as well as the potential health disparities in access to PM. This study helps to frame policies for implementing PM in clinical practice. PMID- 29451917 TI - Perceived behavioral control as a potential precursor of walking three times a week: Patient's perspectives. AB - BACKGROUND: Behavior change theories can identify people's main motivations to engage in recommended health practices and thus provide better tools to design interventions, particularly human centered design interventions. OBJECTIVES: This study had two objectives: (a) to identify salient beliefs about walking three times a week for 30 minutes nonstop among patients with hypertension in a low resource setting and, (b) to measure the relationships among intentions, attitudes, perceived social pressure and perceived behavioral control about this behavior. METHODS: Face-to-face interviews with 34 people living with hypertension were conducted in September-October 2011 in Lima, Peru, and data analysis was performed in 2015. The Reasoned Action Approach was used to study the people's decisions to walk. We elicited people's salient beliefs and measured the theoretical constructs associated with this behavior. RESULTS: Results pointed at salient key behavioral, normative and control beliefs. In particular, perceived behavioral control appeared as an important determinant of walking and a small set of control beliefs were identified as potential targets of health communication campaigns, including (not) having someone to walk with, having work or responsibilities, or having no time. CONCLUSIONS: This theory-based study with a focus on end-users provides elements to inform the design of an intervention that would motivate people living with hypertension to walk on a regular basis in low-resource settings.

PMID- 29451918 TI - Manipulation of the rhizosphere microbial community through application of a new bio-organic fertilizer improves watermelon quality and health. AB - Bio-organic fertilizers (BOFs) combine functional microbes with a suitable substrate and have been shown to effectively suppress soil-borne diseases and promote plant growth. Here, we developed a novel bio-organic fertilizer (BOF) by fermentation of a cow plus chicken manure (M) compost using Fen-liquor Daqu (FLD) as a fermentation starter and compared the compositions of bacterial and fungal communities in the rhizosphere soil of watermelon plants after treatment with different fertilizers. Further, we aimed to explore the mechanisms underlying plant-promoting and disease (Fusarium wilt)-suppressing activities of each rhizosphere microbial community. The microbial communities of soil amended with cow plus chicken manure compost (S+M), soil amended with the BOF (S+BOF), and untreated control soil (S) without plants were analyzed through sequence analysis using the Illumina MiSeq platform. The results showed that a new microbial community was formed in the manure compost after fermentation by the Daqu. Application of the BOF to the soil induced remarkable changes in the rhizosphere microbial communities, with increased bacterial diversity and decreased fungal diversity. Most importantly, S+BOF showed the lowest abundance of Fusarium. Moreover, watermelon quality was higher (P < 0.05) in the S+BOF than in the S+M treatment. Thus, application of the BOF favorably altered the composition of the rhizosphere microbial community, suppressing Fusarium wilt disease and promoting plant quality. PMID- 29451920 TI - An upstream sequence modulates phenazine production at the level of transcription and translation in the biological control strain Pseudomonas chlororaphis 30-84. AB - Phenazines are bacterial secondary metabolites and play important roles in the antagonistic activity of the biological control strain P. chlororaphis 30-84 against take-all disease of wheat. The expression of the P. chlororaphis 30-84 phenazine biosynthetic operon (phzXYFABCD) is dependent on the PhzR/PhzI quorum sensing system located immediately upstream of the biosynthetic operon as well as other regulatory systems including Gac/Rsm. Bioinformatic analysis of the sequence between the divergently oriented phzR and phzX promoters identified features within the 5'-untranslated region (5'-UTR) of phzX that are conserved only among 2OHPCA producing Pseudomonas. The conserved sequence features are potentially capable of producing secondary structures that negatively modulate one or both promoters. Transcriptional and translational fusion assays revealed that deletion of 90-bp of sequence at the 5'-UTR of phzX led to up to 4-fold greater expression of the reporters with the deletion compared to the controls, which indicated this sequence negatively modulates phenazine gene expression both transcriptionally and translationally. This 90-bp sequence was deleted from the P. chlororaphis 30-84 chromosome, resulting in 30-84Enh, which produces significantly more phenazine than the wild-type while retaining quorum sensing control. The transcriptional expression of phzR/phzI and amount of AHL signal produced by 30-84Enh also were significantly greater than for the wild-type, suggesting this 90-bp sequence also negatively affects expression of the quorum sensing genes. In addition, deletion of the 90-bp partially relieved RsmE mediated translational repression, indicating a role for Gac/RsmE interaction. Compared to the wild-type, enhanced phenazine production by 30-84Enh resulted in improvement in fungal inhibition, biofilm formation, extracellular DNA release and suppression of take-all disease of wheat in soil without negative consequences on growth or rhizosphere persistence. This work provides greater insight into the regulation of phenazine biosynthesis with potential applications for improved biological control. PMID- 29451921 TI - The effectiveness of non-surgical intervention (Foot Orthoses) for paediatric flexible pes planus: A systematic review: Update. AB - BACKGROUND: Flexible pes planus (flat feet) in children is a common presenting condition in clinical practice due to concerns amongst parents and caregivers. While Foot Orthoses (FOs) are a popular intervention, their effectiveness remains unclear. Thus, the aim of this systematic review was to update the current evidence base for the effectiveness of FOs for paediatric flexible pes planus. METHODS: A systematic search of electronic databases (Cochrane, Medline, AMED, EMBASE, CINHAL, SportDiscus, Scopus and PEDro) was conducted from January 2011 to July 2017. Studies of children (0-18 years) diagnosed with flexible pes planus and intervention to be any type of Foot Orthoses (FOs) were included. This review was conducted and reported in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. McMaster critical review form for quantitative studies, was used to assess the methodological quality of the included studies. Given the heterogeneity of the included studies, a descriptive synthesis of the included studies was undertaken. RESULTS: Out of 606 articles identified, 11 studies (three RCTs; two case-controls; five case-series and one single case study) met the inclusion criteria. A diverse range of pre fabricated and customised FOs were utilised and effectiveness measured through a plethora of outcomes. Summarised findings from the heterogeneous evidence base indicated that FOs may have a positive impact across a range of outcomes including pain, foot posture, gait, function and structural and kinetic measures. Despite these consistent positive outcomes reported in several studies, the current evidence base lacks clarity and uniformity in terms of diagnostic criteria, interventions delivered and outcomes measured for paediatric flexible pes planus. CONCLUSION: There continues to remain uncertainty on the effectiveness of FOs for paediatric flexible pes planus. Despite a number of methodological limitations, FOs show potential as a treatment method for children with flexible pes planus. PROSPERO REGISTRATION NUMBER: CRD42017057310. PMID- 29451923 TI - To what extent do potential conservation donors value community-aspects of conservation projects in low income countries? AB - There is a major gap in funding required for conservation, especially in low income countries. Given the significant contribution of taxpayers in industrialized countries to funding conservation overseas, and donations from membership organisation, understanding the preferences of ordinary people in a high income country for different attributes of conservation projects is valuable for future marketing of conservation. We conducted a discrete choice experiment with visitors to a UK zoo, while simultaneously conducting a revealed preference study through a real donation campaign on the same sample. Respondents showed the highest willingness to pay for projects that have local community involvement in management (95% confidence interval L9.82 to L15.83), and for improvement in threatened species populations (L2.97 - L13.87). Both of these were significantly larger than the willingness to pay for projects involving provision of alternative livelihoods, or improving the condition of conservation sites. Results of the simultaneous donation campaign showed that respondents were very willing to donate the suggested L1 or above donation (88% made a donation, n = 1798); there was no effect of which of the two campaigns they were exposed to (threatened species management or community involvement in management). The small number of people who did not make a donation had a higher stated willingness to pay within the choice experiment, which may suggest hypothetical bias. Conservationists increasingly argue that conservation should include local communities in management (for both pragmatic and moral reasons). It is heartening that potential conservation donors seem to agree. PMID- 29451922 TI - Identifying classifier input signals to predict a cross-slope during transtibial amputee walking. AB - Advanced prosthetic foot designs often incorporate mechanisms that adapt to terrain changes in real-time to improve mobility. Early identification of terrain (e.g., cross-slopes) is critical to appropriate adaptation. This study suggests that a simple classifier based on linear discriminant analysis can accurately predict a cross-slope encountered (0 degrees , -15 degrees , 15 degrees ) using measurements from the residual limb, primarily from the prosthesis itself. The classifier was trained and tested offline using motion capture and in-pylon sensor data collected during walking trials in mid-swing and early stance. Residual limb kinematics, especially measurements from the foot, shank and ankle, successfully predicted the cross-slope terrain with high accuracy (99%). Although accuracy decreased when predictions were made for test data instead of the training data, the accuracy was still relatively high for one input signal set (>89%) and moderate for three others (>71%). This suggests that classifiers can be designed and generalized to be effective for new conditions and/or subjects. While measurements of shank acceleration and angular velocity from only in-pylon sensors were insufficient to accurately predict the cross-slope terrain, the addition of foot and ankle kinematics from motion capture data allowed accurate terrain prediction. Inversion angular velocity and foot vertical velocity were particularly useful. As in-pylon sensor data and shank kinematics from motion capture appeared interchangeable, combining foot and ankle kinematics from prosthesis-mounted sensors with shank kinematics from in-pylon sensors may provide enough information to accurately predict the terrain. PMID- 29451924 TI - Late effects awareness website for pediatric survivors of acute lymphocytic leukemia. AB - OBJECTIVES: Every day 43 children are newly diagnosed with cancer. Fortunately, almost 90% of these childhood cancer patients will survive. However, 60-90% of these survivors will experience late effects, health problems that occur months or years after treatment has ended. Late effects could occur as a result of the disease, its treatment, and patient-related factors. The two main objectives of this research are to: 1) Examine the existence of all web-based resources for childhood cancer survivors with acute lymphocytic leukemia which focus on medical and psychological aspects of late effects, and 2) Create an innovative website specifically designed to fill this void. MATERIALS AND METHODS: A systematic literature review, followed by input from >20 different organizations, resulted in the creation of LEAP3 AHEAD (Late Effects Awareness for Patients, Physicians and the Public; Advancing Health and Eliminating All Disparities), a multi dimensional website centering on late effects. RESULTS: An extensive review revealed 14 pediatric cancer websites, none of which focused exclusively on late effects. LEAP3 AHEAD is the first interactive website for acute lympocytic leukemia childhood cancer survivors and families, as well as physicians, and the public to: a) increase awareness about risks, detection, diagnosis, treatment, and prevention of medical and psychological late effects, b) provide suggestions to successfully reintegrate into schools, careers, and socially, and c) present opportunities including camps, scholarships, and pet therapy programs. CONCLUSION: LEAP3 AHEAD is the first national website to provide a comprehensive, accessible, affordable, and multi-dimensional resource for pediatricians, internists, nurse practitioners, psychologists, survivors and their families, as well as the public about late effects. PMID- 29451926 TI - Coronally Advanced Flap With or Without Subepithelial Connective Tissue Graft for the Treatment of Single Recession: 5-Year Outcomes from a Comparative Study. AB - Gingival recession can cause an esthetic impairment or dentin hypersensitivity due to root surface exposure to the oral cavity. These conditions may require specific surgical interventions to achieve root coverage. This controlled clinical trial on 20 subjects compared coronally advanced flap (CAF) technique and CAF plus subepithelial connective tissue graft (CTG) for the treatment of single maxillary gingival recession. Recession height (REC) and complete root coverage (CRC) were considered as primary outcomes. The residual REC was 2.90 +/- 0.99 mm at baseline, 1.10 +/- 0.99 mm after 1 year, and 1.15 +/- 1.06 mm after 5 years in the CAF group and 2.70 +/- 0.48 mm at baseline, 0.55 +/- 0.69 mm after 1 year, and 0.44 +/- 0.62 mm after 5 years in the CAF + CTG group. The differences between groups at 5 years of follow-up was statistically significant. CRC was obtained in 60% of teeth in the CAF group and in 70% of teeth in the CAF + CTG group at the 5-year follow-up. The results showed a significant difference between CAF and CAF + CTG techniques for the treatment of single recession with regard to REC; no significant difference was found in the percentage of teeth presenting CRC after 5 years. PMID- 29451925 TI - The impact of "Option B" on HIV transmission from mother to child in Rwanda: An interrupted time series analysis. AB - BACKGROUND: Nearly a quarter of a million children have acquired HIV, prompting the implementation of new protocols-Option B and B+-for treating HIV+ pregnant women. While efficacy has been demonstrated in randomized trials, there is limited real-world evidence on the impact of these changes. Using longitudinal, routinely collected data we assessed the impact of the adoption of WHO Option B in Rwanda on mother to infant transmission. METHODS: We used interrupted time series analysis to evaluate the impact of Option B on mother-to-child HIV transmission in Rwanda. Our primary outcome was the proportion of HIV tests in infants with positive results at six weeks of age. We included data for 20 months before and 22 months after the 2010 policy change. RESULTS: Of the 15,830 HIV tests conducted during our study period, 392 tested positive. We found a significant decrease in both the level (-2.08 positive tests per 100 tests conducted, 95% CI: -2.71 to -1.45, p < 0.001) and trend (-0.11 positive tests per 100 tests conducted per month, 95% CI: -0.16 to -0.07, p < 0.001) of test positivity. This represents an estimated 297 fewer children born without HIV in the post-policy period or a 46% reduction in HIV transmission from mother to child. CONCLUSIONS: The adoption of Option B in Rwanda contributed to an immediate decrease in the rate of HIV transmission from mother to child. This suggests other countries may benefit from adopting these WHO guidelines. PMID- 29451927 TI - A Retrospective Tomographic and Histologic Analysis of Horizontal Bone Augmentation in Maxillary Atrophic Ridges Using Resorbable Membrane with Anorganic Bovine Bone-Derived Mineral and Plasma Rich in Growth Factors. AB - A total of six patients treated from 2010 to 2014, having a knife-edge ridge (Cawood-Howell Class IV resorbed ridges) and requiring an implant-prosthetic rehabilitation, were selected. Tomographic measurement of the edentulous ridges was performed before grafting and after implant placement. At 6 months postgraft, a total of 41 implants had been inserted, 17 in the posterior region, 12 in the central region, and 12 in the anterior region. No surgical or healing complications were recorded, and the prostheses were loaded 6 to 9 months after implant placement. The tomographic measurements demonstrated an increased area in all the sites where bone augmentation had been performed, corresponding to 11.1% in the anterior region, 94.7% in the central region, and 760.2% in the posterior region. Histology was performed in 2 patients, one at 1 year and the other at 5 years postgrafting, and demonstrated the presence of mature lamellar bone tissue and newly formed bone without morphologic signs of necrosis or inflammation and a reduction of 50% to 30% of the grafted material. Although this study included a small number of clinical cases, it demonstrated how management of the atrophic maxillary ridge, with the goal of implant placement, may be handled using a technique that requires a single anorganic bovine bone-derived mineral treatment combined with a plasma rich in growth factors and resorbable collagen membrane.

AB - This case series describes a treatment method in which the natural tooth was used as the temporary and permanent reconstruction after immediate implantation in the esthetic zone of periodontally compromised patients. Five patients with a hopeless tooth in the esthetic zone due to periodontal causes were included. The tooth was extracted, and immediate implantation protocol was followed. The extracted tooth was adapted over a temporary abutment during the osseointegration period, and the same tooth served as the final prosthetic reconstruction with a customized zirconia abutment. Esthetic outcome was satisfactory to the patients, and no biologic or prosthetic complications were observed up to 3 years. The technique could be recommended, especially in the esthetic area of periodontally compromised patients who have intact clinical crowns.

Six patients, each presenting one methacrylate cement retained implant restoration and showing peri-implant inflammation and bone loss, were treated. All the cases were negative for bleeding on probing after 6 weeks, and this was maintained at 1 year of follow-up from nonsurgical therapy and crown refixation with alternative and resorbable cement.

AB - Frail older adults often experience swallowing disorders, prompting nursing staff to crush tablets, open capsules, and mix drugs into their meals or gelled water. However, crushing drugs can lead to pharmacological and gustatory problems. As crushed drugs can stay in prolonged contact with oral microbial biofilm, the current study aimed to investigate their antimicrobial properties. Crushed drugs were diluted in 1 mL of isotonic water and assayed in vitro for: (a) growth inhibition of five bacterial strains and Candida albicans by the diffusion method; (b) inhibition of Streptococcus salivarius and C. albicans biofilm formation; and (c) elimination of a preformed biofilm of S. salivarius and C. albicans after 5-minute contact. Eight of 29 crushed drugs inhibited bacterial and/or fungal growth on agar plates. Twenty-eight of 29 crushed drugs reduced the total biomass when incubated with S. salivarius, and 28 of 29 crushed drugs inhibited C. albicans biofilm formation. Preformed biomass was reduced by >=25% by seven of 29 drugs. Crushed drugs may unbalance oral ecosystems and contribute to oral inflammation. [Res Gerontol Nurs. 2018; 11(2):82-90.]. PMID- 29451933 TI - Depressive Symptoms and Physical Frailty in Older Adults With Chronic Heart Failure: A Cross-Sectional Study. AB - Depressive symptoms and physical frailty have been reported to be predictive of adverse outcomes in individuals with heart failure (HF). Depressive symptoms could be a predisposing factor of physical frailty in older adults. Despite the high prevalence of HF, few studies on the relationship between these two factors have been performed in older adults with HF. To identify the relationship between depressive symptoms and physical frailty in HF, 190 older adults with HF were recruited from an outpatient clinic at a tertiary hospital in South Korea. The prevalence of depressive symptoms and physical frailty in older adults with HF was 30% (n = 57) and 61.6% (n = 117), respectively. Multivariate logistic regression revealed that depressive symptoms most strongly increased the risk of physical frailty after adjusting for confounding factors. Early detection of depressive symptoms might be useful to identify the status of physical frailty at the illness trajectories of HF in older adults and for judicious allocation of disease management strategies.

AB - Nurses working at general hospitals face difficulties in providing dementia care. The current study examined aged care nurses' dementia care practices in the hospital setting and developed a dementia care checklist that nurses can use to review their own care practice. A self-administered questionnaire was given to 676 participants; responses were collected from 595 participants. Exploratory factor analysis identified six factors (e.g., patient understanding prompted by concern and interest for the patient, respect for patients' voluntary behavior, early detection of abnormalities) among the questionnaire's 28 items. This analysis provided a framework for the checklist and verified that it had satisfactory internal consistency and construct validity. The frequency of care practices varied with participants' knowledge of dementia care requirements, satisfaction with their own dementia care practice, confidence in their ability to judge patients' physical condition, and cooperation with colleagues. This checklist might improve dementia care in hospital settings. [Res Gerontol Nurs. 2018; 11(2):91-102.].

This study sought to characterize the economic implications of implant choice. A retrospective review was undertaken of 201 consecutive patients with operatively treated OTA type 44B and 44C ankles. A Nationwide Inpatient Sample query was performed to estimate the incidence of ankle fractures requiring fibular plating, and a Monte Carlo simulation was conducted with the estimated at risk US population for associated plate-specific costs. The authors estimated an annual incidence of operatively treated ankle fractures in the United States of 59,029. The average cost was $90.86 (95% confidence interval, $90.84-$90.87) for a one-third tubular plate vs $746.97 (95% confidence interval, $746.55-$747.39) for an anatomic plate. Across the United States, use of only one-third tubular plating over anatomic plating would result in statistically significant savings of $38,729,517 (95% confidence interval, $38,704,773-$38,754,261; P<.0001). General use of one-third tubular plating instead of anatomic plating whenever possible for fibula fractures could result in cost savings of up to nearly $40 million annually in the United States. Unless clinically justifiable on a per case basis, or until the advent of studies showing substantial clinical benefit, there currently is no reason for the increased expense from widespread use of anatomic plating for fractures amenable to one-third tubular plating.

No specific incidence of subtle injuries has been reported; however, almost one-third are missed on initial review. These missed injuries are a common cause of litigation. Although seen in high-energy injuries with direct application of forces, they are also associated with lower-energy indirect mechanisms, often on the athletic field. This article provides a topical review of subtle Lisfranc disruptions, focusing on contemporary perspectives, and describes a modification to the most prevalent classification system.

AB - Compromise of bony support presents a difficult problem in acetabular revision surgery. Although various methods have been proposed to cope with this problem, they have had variable results and little long-term follow-up. The authors reviewed the results of 37 patients undergoing custom triflange revision surgery. Two patients were lost to follow-up, leaving 35 patients with minimum 10-year clinical and radiographic follow-up. Thirty-two (91%) of 35 components were unrevised and functioning well at minimum 10-year follow-up. One component placed for pelvic discontinuity loosened at 12 years after surgery but was converted to a conventional total hip. One component had failure of 3 ischial screws at 6 months; however, at 11 years, the patient had no additional clinical or radiographic evidence of loosening. The average Harris hip score was 28 preoperatively and 90 postoperatively. Two components (6%) were removed for infection. There were no dislocations, fractures, or nerve injuries. Revision of large acetabular defects with a custom triflange component resulted in reliably good to excellent results at minimum 10-year follow-up. [Orthopedics. 2018; 41(3):e316-e320.]. PMID- 29451938 TI - The Management of Cerebrospinal Fluid Leak After Anterior Cervical Decompression Surgery. AB - Cerebrospinal fluid (CSF) leak is a rare but potentially troublesome and occasionally catastrophic complication after anterior cervical decompression surgery. There is limited literature describing this complication, and the management of CSF leak varies. The aim of this study was to retrospectively review the treatment of cases with CSF leak and develop a management algorithm. A series of 14 patients with CSF leak from January 2011 to May 2016 were included in this study. Their characteristics, management of CSF leak, and outcomes were documented. There were 5 male and 9 female patients. Mean age at surgery was 57.1+/-9.9 years (range, 37-76 years). All instances of CSF leak, except 1 noted postoperatively, were indirectly repaired intraoperatively. A closed straight wound drain was placed for all patients. A lumbar subarachnoid drain was placed immediately after surgery in 4 patients and postoperatively in 7 patients. In 1 patient, lumbar drain placement was unsuccessful. In 2 additional patients, the surgeon decided not to place a lumbar drain. One patient developed meningitis and recovered after antibiotic therapy with meropenem and vancomycin. Another patient had a deep wound infection and required a revision surgery. Wound drains and lumbar drains should be immediately considered when CSF leak is identified. Antibiotics also should be considered to prevent intradural infection. [Orthopedics. 2018; 41(2):e283-e288.].

AB - This retrospective review evaluated the mid-term outcomes of cemented reverse shoulder arthroplasty in patients who use the shoulder for weight bearing (WB) vs non-weight-bearing (NWB) patients. Twenty-five shoulders of 21 patients who used their upper extremity for WB (WB group) were treated with cemented reverse shoulder arthroplasty and followed for a minimum of 5 years postoperatively (average, 73 months). Seventy-five consecutive shoulders of 72 patients who were NWB (NWB group) were treated and matched for duration of follow-up (average, 72 months) to serve as a control group. Patients were followed clinically and radiographically. There were no statistically significant differences between the WB group and the NWB group regarding final outcome scores or range of motion. Patient satisfaction was similar between the WB group (92%) and the NWB group (94%). The scapular notching rate was 20% in the WB group compared with 5% in the NWB group (P=.041). Humeral loosening occurred in 12% of the WB group vs 0% of the NWB group (P=.014). The complication rate was higher in the WB group than in the NWB group (12% vs 4%). The WB group and the NWB group had similar outcome scores, range of motion improvements, and patient satisfaction after reverse shoulder arthroplasty. At mid-term follow-up, the WB group had a higher scapular notching rate, humeral loosening rate, and complication rate than the NWB group. [Orthopedics. 2018; 41(3):e328-e333.]. PMID- 29451940 TI - Patient Factors Associated With Methicillin-Resistant Staphylococcus aureus Septic Arthritis in Children. AB - Staphylococcus aureus is the most common causative organism in pediatric septic arthritis, with methicillin-resistant Staphylococcus aureus (MRSA) being responsible for a significant portion of these infections. Early identification and initiation of proper treatment may improve outcomes by minimizing potential morbidity. The purpose of this study was to identify variables obtained on initial patient presentation associated with MRSA septic arthritis. Sixteen factors were retrospectively evaluated in 109 consecutive pediatric patients diagnosed with culture-confirmed septic arthritis. Graphical and logistical regression analyses were employed to determine factors independently predictive of MRSA septic arthritis. Twenty-seven (25%) patients had MRSA and 82 (75%) had non-MRSA septic arthritis. C-reactive protein of 13.7 mg/L or greater, duration of symptoms of 4 days or more, heart rate of 126 beats per minute or greater, and absolute neutrophil count of 8.72*103 cells/uL or greater were associated with MRSA septic arthritis. Ultimately, 98% of patients with 1 or no risk factors had non-MRSA and 96% of patients with MRSA septic arthritis had 2 or more positive risk factors. Elevated C-reactive protein, duration of symptoms, heart rate, and absolute neutrophil count are predictive of MRSA infection in the setting of pediatric septic arthritis and can be obtained on initial evaluation. In patients for whom there is concern for MRSA infection, this may guide more expedient treatment, such as early initiation of contact precautions and appropriate antibiotic therapy before culture results become available.

AB - As the number of anatomic total shoulder arthroplasties performed on younger patients continues to grow, return to work after surgery becomes increasingly important. The purpose of this study was to evaluate the ability of anatomic total shoulder arthroplasty to return patients 55 years or younger to work postoperatively. A retrospective review was performed of consecutive anatomic total shoulder arthroplasty patients. Inclusion criteria were age 55 years or younger at surgery, greater than 2 years of follow-up, and employment within 3 years of surgery. Employment was stratified by intensity of work (sedentary, light, moderate, or heavy). Return to work status and time out of work were also evaluated. Fifty-two patients worked before surgery. Average age was 48.4 years, with average follow-up of 5.4 years. Seventy-three percent were male, and average body mass index was 28.0 kg/m2. Average visual analog scale score improved from 5.5 to 0.9 (P<.0001) and American Shoulder and Elbow Society score improved from 39.9 to 88.3 (P<.0001). Forty-eight (92%) of 52 returned to work postoperatively after an average of 2.1 months. When stratified by intensity, all patients with sedentary, light, or moderate work returned, whereas 64% returned to heavy work (P<.01). Eighty-seven percent were satisfied to very satisfied after surgery. In summary, most patients (92%) who undergo anatomic total shoulder arthroplasty at 55 years or younger return to work, on average, 2.1 months after surgery. [Orthopedics. 2018; 41(3):e310-e315.]. PMID- 29451942 TI - Incidence of and Risk Factors for Knee Collateral Ligament Injuries With Proximal Tibia Fractures: A Study of 32,441 Patients. AB - Proximal tibia fractures are associated with concurrent collateral ligament injuries. Failure to recognize these injuries may lead to chronic knee instability. The purpose of this study was to identify risk factors for concurrent collateral ligament injuries with proximal tibia fractures and their association with inpatient outcomes. A total of 32,441 patients with proximal tibia fractures were identified in the 2011-2012 National Trauma Data Bank. A total of 1445 (4.5%) had collateral ligament injuries, 794 (2.4%) had injuries to both collateral ligaments, 456 (1.4%) had a medial collateral ligament injury only, and 195 (0.6%) had a lateral collateral ligament injury only. On multivariate analysis, risk factors found to be associated with collateral ligament injuries included distal femur fracture (odds ratio, 2.1), pedestrian struck by motor vehicle (odds ratio, 2.0), obesity (odds ratio, 1.6), young age (odds ratio, 1.9 for 18 to 29 years vs 40 to 49 years), motorcycle accident (odds ratio, 1.5), and Injury Severity Score of 20 or higher (odds ratio, 1.4). In addition, patients with simultaneous injuries to both collateral ligaments had higher odds of inpatient adverse events (odds ratio, 1.51) and longer hospital stay (mean, 2.27 days longer). The risk factors reported by this study can be used to identify patients with proximal tibia fractures who may warrant more careful and thorough evaluation and imaging of their knee collateral ligaments.

AB - The co-occurrence of a mental illness and a substance abuse disorder (SUD) is common and has been referred to as a "dual diagnosis" (DD). Although studies have independently investigated mental illness alone and SUD alone, few have examined the effects of these entities combined on complications. A search of the Medicare database from 2005 to 2012 identified 2000 DD patients who underwent total hip arthroplasty (THA). They were compared with 86,976 patients with mental illness only and 590,689 controls (no mental illness or SUD). Medical comorbidities and postoperative complications at 30-day, 90-day, and minimum 2-year time points were analyzed. There was a significant increase (P<.001) in 7 (53.8%) of 13 recorded postoperative medical complications, including acute renal failure (odds ratio [OR], 1.78), postoperative anemia (OR, 1.31), and blood transfusion (OR, 1.24), at the 90-day time point. In addition, there was a statistically significant increase overall in periprosthetic infection (periprosthetic joint infection OR, 4.30; P<.001), periprosthetic fracture (OR, 2.80; P<.001), dislocation (OR, 6.38; P<.001), and the need for THA revision (OR, 3.58; P<.001). When compared with patients with mental illness only, DD patients remained at significantly (P<.001) increased risk for 90-day and overall postoperative surgical complications, including dislocation, periprosthetic joint infection, and THA revision. Patients with a DD were at significant risk for perioperative complications compared with both control patients and patients with mental illness only. Studies investigating only psychiatric disease or only SUD may miss a vulnerable cohort. Further investigation is needed to exactly define to what extent DD amplifies complication rates.

AB - The immunosuppressive regimens required for hematopoietic stem cell transplantation predispose recipients to complications, including avascular necrosis. Cancer-related comorbidities, immunosuppression, and poor bone quality theoretically increase the risk for perioperative medical complications, infection, and implant-related complications in total joint arthroplasty. This study reviewed 20 primary total hip arthroplasties for avascular necrosis in 14 patients. Outcomes were assessed at routine clinical visits and Harris hip scores were calculated. Follow-up radiographs were evaluated for component malposition, loosening, polyethylene wear, and osteolysis. Average follow-up was 44.5 months for all patients. Postoperative clinical follow-up revealed good to excellent outcomes, with significant improvement in functional outcome scores. There were no periprosthetic infections or revisions for aseptic loosening. There was 1 dislocation on postoperative day 40, which was treated successfully with a closed reduction. Two patients with a prior history of venous thromboembolism developed a pulmonary embolus on postoperative day 13 and 77, respectively. Four patients died several months to years after arthroplasty of complications unrelated to the surgical procedure. Total hip arthroplasty can both be safely performed and greatly improve quality of life in recipients of hematopoietic stem cell transplantation who develop avascular necrosis. However, prolonged venous thromboembolism prophylaxis should be carefully considered in this high-risk patient population. [Orthopedics. 2018; 41(2):e257-e261.]. PMID- 29451945 TI - The Effects of Platelet-Rich Plasma and Activated Collagen on Wound Healing in Primary Total Joint Arthroplasty. AB - Wound healing remains a concern in primary total joint arthroplasty, given the risk of deep infections arising from hematomas, wound separations, and superficial infections. If wound additives can prevent these early complications, their universal application would be cost-effective. This study examined whether 2 wound additives, platelet-rich plasma (PRP) and activated collagen, would improve postoperative wound healing and reduce complications in primary total joint arthroplasty. A prospective, randomized controlled study was conducted using 3 cohorts with 30 patients each (group 1: PRP; group 2: activated collagen; and group 3: control). These patients were examined at 2 and 6 weeks postoperatively, at which time the following data were recorded: 6 wound measurements, total postoperative blood loss, complications of superficial infections, and reoperations. The PRP and the activated collagen groups showed early improvement in 3 of the 6 wound scores at 2 weeks, but these early results were not present at 6 weeks. In addition, there was a statistically significant reduction in blood loss in both the PRP and the activated collagen groups, as compared with the control group. Furthermore, high-risk patients had a statistically significant reduction in total complication rates in both the PRP and the activated collagen groups, as compared with the control group. On the basis of this study, these additives are not recommended for routine primary joint arthroplasty; however, the data suggest possible benefits for high-risk patients and those for whom blood loss may be an issue.

PMID- 29451946 TI - First experience in Switzerland in Phe508del homozygous cystic fibrosis patients with end-stage pulmonary disease enrolled in a lumacaftor-ivacaftor therapy trial - preliminary results. AB - AIMS OF THE STUDY: Cystic fibrosis is the most common genetic disorder in Caucasians. The combination of the cystic fibrosis transmembrane conductance regulator (CFTR) corrector lumacaftor / potentiator ivacaftor (LUM/IVA) has been shown to increase forced expiratory volume in 1 second (FEV1) moderately, but predominantly reduce acute exacerbation rate (AER) in Phe508del homozygous cystic fibrosis patients; however, patients with FEV1 <40% predicted were excluded from studies. We used LUM/IVA on a "compassionate use" basis in cystic fibrosis patients with end-stage pulmonary disease. Our aim was to evaluate if this patient cohort tolerates LUM/IVA treatment and if there is clinical stabilisation. Lung transplantation (LTX) is the ultimate treatment option for these patients despite maximal therapy. If LTX candidates stabilise clinically, conditions for LTX, when it is indicated, improve. This is particularly important in countries such as Switzerland with a low organ donation rate and long waiting times for suitable donor organs. METHODS: We included all patients from the Adult Cystic Fibrosis Centre at the University Hospital Zurich with Phe508del homozygous genotype and a predicted FEV1 <40% or being evaluated or already listed for LTX. Clinical outcome data comprised AER, 6-minute walking distance (6 MWD), FEV1, forced vital capacity (FVC), mid-expiratory flow (MEF 25-75%), sweat chloride, body mass index (BMI) and quality of life. Respiratory-related adverse events (RAEs) were recorded. LUM/IVA treatment was initiated at a low dose and the dose increased stepwise. RESULTS: Twenty patients were on trial with LUM/IVA; at the cut-off date, 6-month follow-up was complete for 10 patients. RAEs were severe and occurred early. The dropout rate due to RAE or lack of clinical success was 20%. Median AER decreased from 2.5 in the 6 months pre-treatment to 1 during the observation period. FEV1 increased from 32 to 34.5% predicted, p = 0.292. The 6-MWD increased by a median 33 m (p = 0.6086). Sweat chloride decreased significantly by a median of 25 mmol/l (p = 0.0003). Median BMI increased from 19 to 19.9 kg/m2 (p = 0.1488). At the cut-off, three previously listed patients were paused on the transplant waiting list. CONCLUSION: Phe508del homozygous cystic fibrosis patients with end-stage pulmonary disease tolerated LUM/IVA, although RAEs occurred early and were severe. This positive finding was probably due to the stepwise dose increases. There was clinical benefit mainly from reduction in AER and stabilisation of lung function. We propose that all suitable Phe508del homozygous cystic fibrosis patients with end-stage pulmonary disease should have a trial of LUM/IVA treatment in experienced centres. PMID- 29451947 TI - A wild bootstrap approach for the Aalen-Johansen estimator. AB - We suggest a wild bootstrap resampling technique for nonparametric inference on transition probabilities in a general time-inhomogeneous Markov multistate model. We first approximate the limiting distribution of the Nelson-Aalen estimator by repeatedly generating standard normal wild bootstrap variates, while the data is kept fixed. Next, a transformation using a functional delta method argument is applied. The approach is conceptually easier than direct resampling for the transition probabilities. It is used to investigate a non-standard time-to-event outcome, currently being alive without immunosuppressive treatment, with data from a recent study of prophylactic treatment in allogeneic transplanted leukemia patients. Due to non-monotonic outcome probabilities in time, neither standard survival nor competing risks techniques apply, which highlights the need for the present methodology. Finite sample performance of time-simultaneous confidence bands for the outcome probabilities is assessed in an extensive simulation study motivated by the clinical trial data. Example code is provided in the web-based Supplementary Materials. PMID- 29451948 TI - Duration of maternal mental health-related outcomes after an infant's death: A retrospective matched cohort study using linkable administrative data. AB - BACKGROUND: Mothers have increased mental illness such as anxiety and depression after the death of a child. We examine the duration of this worsening of mental health. METHODS: The mental health of all mothers who experience the death of an infant (< 1 years old) in Manitoba, Canada between April 1, 1999 and March 31, 2011 (n = 534) is examined in the 4 years leading up to, and the 4 years following, the death of their child. Mental health-related outcomes of these mothers are compared with a matched (3:1) cohort of mothers who did not experience the death of a child (n = 1,602). Three mental health-related outcomes are examined: depression diagnoses, anxiety diagnoses, and use of psychotropic medications. RESULTS: Compared with mothers who did not experience the death of a child, mothers experiencing this event had higher rates of anxiety diagnoses and psychotropic prescriptions starting 6 months before the death. Elevated rates of anxiety continued for the first year and elevated rates of psychotropic prescriptions continued for 6 months after the death of the child. Mothers who experienced the death of a child had higher rates of depression diagnoses in the year after the death. Relative rates (RR) of depression (RR = 4.94), anxiety (RR = 2.21), and psychotropic medication use (RR = 3.18) were highest in the 6 months after the child's death. CONCLUSIONS: Elevated rates of depression, anxiety, and psychotropic medication use after the death of a child end within 1 year of the child's death.

AB - BACKGROUND: During transradial (TR) access, it remains unclear whether differences in baseline patients characteristics and hemostasis care impact the rate of radial artery occlusion (RAO). We sought to compare the rate of RAO after TR access with the 6 French(Fr) Glidesheath Slender (GSS6Fr, Terumo, Japan) or a standard 5 Fr sheath in Japanese and non-Japanese patients. METHODS AND RESULTS: The Radial Artery Patency and Bleeding, Efficacy, Adverse evenT (RAP and BEAT) trial randomized 1,836 patients undergoing TR coronary angiography and/or interventions to receive the GSS6Fr or the standard 5 Fr Glidesheath (GS5Fr, Terumo, Japan). Out of this study population, 1,087 were Japanese patients and 751 non-Japanese patients. The overall incidence of RAO was significantly higher in Japanese patients (3.6% vs. 1.2%, P = 0.002). Use of GSS6Fr was associated with higher rates of RAO than GS5Fr in Japanese patients (5% vs. 2.2%, P = 0.02) and with similar RAO rates in non-Japanese patients (1.3 vs. 1.1%, P = 1). The mean hemostasis time was significantly longer in Japanese patients (378 +/- 253 vs. 159 +/- 136 min, P < 0.001) and more Japanese patients had a hemostasis time of more than 6 hr (16.2% vs. 4.9%, P < 0.0001). Longer hemostasis time was an independent predictor of RAO (OR per additional hour 1.070, 95% CI 1.008-1.136, P = 0.03). CONCLUSIONS: Use of GSS6Fr was associated with a higher rate of RAO than a standard 5 Fr sheath in Japanese patients but not in non-Japanese patients. Whether improvement in post-procedural care and reduced hemostasis time could impact the incidence of RAO in Japanese patients should be further assessed. PMID- 29451950 TI - Intrinsic changes of left ventricular function in patients with Behcet disease and comparison according to systemic disease activity. AB - PURPOSE: Although cardiac manifestation of Behcet disease (BD) has been described in sporadic reports, its timely diagnosis remains difficult. The objective of this study was to describe early cardiac manifestations of BD. We also performed a comprehensive classification of systemic BD activity and compared their cardiac manifestations. METHODS: A prospective screening using speckle tracking echocardiography was performed in 85 patients with BD who had no history of heart disease. After excluding subjects with left ventricular (LV) ejection fraction (LVEF) <50% (n = 1), atrial fibrillation (n = 2), or inadequate echocardiographic images (n = 1), we analyzed their clinical and echocardiographic parameters including LV global longitudinal strains (GLS) and compared them with those of an age- and gender-matched control group (n = 145). Systemic BD activity was classified as minimal (Group A), controlled (Group B), and active (Group C). RESULTS: In 81 study patients (59 females, age of 51 +/- 11 years), echocardiography revealed a mean LVEF of 64 +/- 5% without any significant valvular dysfunction or aortic aneurysm. Although there was no difference in LVEF between the control group and the patient group, the patient group showed significant reduction in GLS (-17.1 +/- 2.9% vs -20.8 +/- 2.2%, P < .001). Groups A (n = 21, 26%), B (n = 47, 58%), and C (n = 13, 58%) consistently showed reduction in GLS compared with the control group. However, there was no significant difference in cardiac manifestations among these groups according to systemic disease activity. CONCLUSION: Patients with BD present intrinsic LV dysfunction despite no apparent abnormality on routine echocardiography. However, their cardiac manifestations are not proportional to systemic BD activity.

AB - BACKGROUND: The purpose of this study was to characterize the clinical course of hearing loss in patients with nasopharyngeal carcinoma (NPC) and the clinical factors affecting its severity. METHODS: The time course of hearing loss in patients with NPC was assessed using threshold shift from baseline and Common Terminology Criteria for Adverse Events (CTCAE) grade. RESULTS: In the chemoradiotherapy (CRT) groups, the threshold shift was significantly higher from 3 months at 4 kHz (P = 2.30 * 10-9 , concurrent CRT only) but not within 2 years posttreatment in the radiotherapy (RT) group. The CRT groups had worse CTCAE grades than the RT group (percentage of latest CTCAE grade >=1: 64.9% vs 29.0%, respectively). Cumulative cisplatin dose and cochlear RT dose significantly affects threshold shifts, especially at high frequencies. CONCLUSION: Although cisplatin led to high frequency hearing impairment from about 3 months posttreatment, RT conferred no significant hearing impairment in the first 2 years. PMID- 29451952 TI - One-Step Synthesis of Hybrid Core-Shell Metal-Organic Frameworks. AB - Epitaxial growth of MOF-on-MOF composite is an evolving research topic in the quest for multifunctional materials. In previously reported methods, the core shell MOFs were synthesized via a stepwise strategy that involved growing the shell-MOFs on top of the preformed core-MOFs with matched lattice parameters. However, the inconvenient stepwise synthesis and the strict lattice-matching requirement have limited the preparation of core-shell MOFs. Herein, we demonstrate that hybrid core-shell MOFs with mismatching lattices can be synthesized under the guidance of nucleation kinetic analysis. A series of MOF composites with mesoporous core and microporous shell were constructed and characterized by optical microscopy, powder X-ray diffraction, gas sorption measurement, and scanning electron microscopy. Isoreticular expansion of microporous shells and orthogonal modification of the core was realized to produce multifunctional MOF composites, which acted as size selective catalysts for olefin epoxidation with high activity and selectivity. PMID- 29451953 TI - Using quantitative tissue phenotype to assess the margins of surgical samples from a pan-Canadian surgery study. AB - BACKGROUND: The purpose of this study was to use quantitative tissue phenotype (QTP) to assess the surgical margins to examine if a fluorescence visualization guided surgical approach produces a shift in the surgical field by sparing normal tissue while catching high-risk tissue. METHODS: Using our QTP to calculate the degree of nuclear chromatin abnormalities, Nuclear Phenotypic Score (NPS), we analyzed 1290 biopsy specimens taken from surgical samples of 248 patients enrolled in the Efficacy of Optically-guided Surgery in the Management of Early staged Oral Cancer (COOLS) trial. Multiple margin specimens were collected from each surgical specimen according to the presence of fluorescence visualization alterations and the distance to the surgical margins. RESULTS: The NPS in fluorescence visualization-altered (fluorescence visualization-positive) samples was significantly higher than that in fluorescence visualization-retained (fluorescence visualization-negative) samples. There was a constant trend of decreasing NPS of margin samples from non-adjacent-fluorescence visualization margins to adjacent-fluorescence visualization margins. CONCLUSION: Our results suggested that using fluorescence visualization to guide surgery has the potential to spare more normal tissue at surgical margins.

PMID- 29451955 TI - Relationship between subchondral bone microstructure and articular cartilage in the osteoarthritic knee using 3T MRI. AB - BACKGROUND: The importance of subchondral bone in the pathogenesis of osteoarthritis (OA) has drawn interest. PURPOSE: To investigate subregional trabecular bone microstructural features and to determine the relationship between cartilage and trabecular bone in the osteoarthritic human knee. STUDY TYPE: Prospective study. SUBJECTS: In all, 92 knees were enrolled and divided into three groups: without OA, mild OA, and severe OA. SEQUENCE: A sagittal 3D balanced fast field echo (3D B-FFE) sequence and FatSat 3D fast field echo (3D FFE) sequence at 3T MRI. ASSESSMENT: The trabecular bone in 12 sites of the knee joint was evaluated using digital topological analysis, and the cartilage thickness in four sites was calculated. STATISTICAL TEST: Trabecular bone and cartilage parameters between groups were compared using analysis of variance (ANOVA) with Bonferroni adjustment, and their correlations were analyzed using Pearson's correlation coefficient. RESULTS: Within both femoral condyles, the trabecular bone structure deteriorated in mild OA, showing a lower bone volume fraction (BVF) (0.15 to 0.12, P < 0.05), higher erosion index (EI) (2.25 to 2.28, P < 0.01), and a lower plate-to-rod ratio (SCR) (6.22 to 5.96, P < 0.05). Within medial and lateral tibia, deterioration in the trabecular bone was also observed, demonstrating a lower BVF (0.15 to 0.12 P < 0.05) and a higher EI (2.25 to 2.61, P < 0.05). Cartilage attrition mainly occurred in the medial joint. Extensive correlations were found between the medial cartilage thickness and subregional trabecular parameters. There was mainly a positive correlation with both femoral BVFs (r > 0.3, P < 0.05), and a negative correlation with the tibia SCR (r < 0.2, P < 0.05). DATA CONCLUSION: In the early stage of OA, trabecular bone osteoporotic changes were observed in both femoral condyles and the tibia. Based on a strong correlation with the medial cartilage thickness, the trabecular structural topological analysis may be useful for elucidating OA onset and progression.

AB - BACKGROUND: The current study sought to advance the existing literature by providing the first assessment of the factorial and discriminant validity of the ICD-11 proposals for posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) in a nationwide level. METHODS: A nationally representative sample from Israel (n = 1,003) using a disorder-specific measure (ITQ; International Trauma Questionnaire) in order to assess PTSD and CPTSD along with the Life Events Checklist and the World Health Organization Well-Being Index. RESULTS: Estimated prevalence rates of PTSD and CPTSD were 9.0 and 2.6%, respectively. The structural analyses indicated that PTSD and disturbances in self-organization symptom clusters were multidimensional, but not necessarily hierarchical, in nature and there were distinct classes that were consistent with PTSD and CPTSD. CONCLUSIONS: These results partially support the factorial validity and strongly support the discriminant validity of the ICD-11 proposals for PTSD and CPTSD in a nationally representative sample using a disorder-specific measure; findings also supported the international applicability of these diagnoses. Further research is required to determine the prevalence rates of PTSD and CPTSD in national representative samples across different countries and explore the predictive utility of different types of traumatic life events on PTSD and CPTSD.

AB - OBJECTIVE: Although admissions of children with anorexia nervosa (AN) are increasing, there remains a dearth of up-to-date knowledge of the course and outcome of early-onset AN. The aim of the present study was to investigate the outcomes of patients with AN onset before the age of 14. METHOD: Sixty-eight consecutive former patients who met the DSM-IV criteria for AN and who had been treated at one of three German university hospitals were asked to participate in a follow-up study. Body mass index, body height, outcome of the eating disorder (ED), psychiatric morbidity, and health related quality of life (HRQoL) were assessed through a personal examination after an average time span of 7.5 years (range: 4.5-11.5 years) after admission. RESULTS: One patient had died. Fifty-two subjects with a mean age of 12.5 (SD 1.0) years at admission and of 20.2 (SD 2.0) years at follow-up agreed to participate in the follow-up assessment, aggregating to 77.9% of the original sample. Approximately 41% of the participants had a good outcome, while 35% and 24% had intermediate and poor outcomes, respectively. Twenty-eight percent of the sample met the DSM-IV criteria for a current non-ED psychiatric disorder, and 64% met the criteria for a past non-ED psychiatric disorder. Mental HRQoL and ED-specific psychopathology was strongly associated with the outcome of AN. Average body height was below the normal range. A higher weight at admission was the only significant positive indicator of outcome. DISCUSSION: Childhood AN is a serious disorder with an unfavorable course in many patients and high rates of chronicity and psychiatric comorbidity in young adulthood. Early detection and intervention are urgently needed. PMID- 29451958 TI - Peripartum cardiomyopathy: Status 2018. AB - Peripartum cardiomyopathy is a rare cardiac condition, overall. However, in certain populations can be found frequently enough and the signs, symptoms, and management should be readily understood. Here we provide an updated overview of this topic. PMID- 29451959 TI - Network analysis: An innovative framework for understanding eating disorder psychopathology. AB - Network theory and analysis is an emerging approach in psychopathology research that has received increasing attention across fields of study. In contrast to medical models or latent variable approaches, network theory suggests that psychiatric syndromes result from systems of causal and reciprocal symptom relationships. Despite the promise of this approach to elucidate key mechanisms contributing to the development and maintenance of eating disorders (EDs), thus far, few applications of network analysis have been tested in ED samples. We first present an overview of network theory, review the existing findings in the ED literature, and discuss the limitations of this literature to date. In particular, the reliance on cross-sectional designs, use of single-item self reports of symptoms, and instability of results have raised concern about the inferences that can be made from network analyses. We outline several areas to address in future ED network analytic research, which include the use of prospective designs and adoption of multimodal assessment methods. Doing so will provide a clearer understanding of whether network analysis can enhance our current understanding of ED psychopathology and inform clinical interventions. PMID- 29451960 TI - Direct Measurement of Charge Regulation in Metalloprotein Electron Transfer. AB - Determining whether a protein regulates its net electrostatic charge during electron transfer (ET) will deepen our mechanistic understanding of how polypeptides tune rates and free energies of ET (e.g., by affecting reorganization energy, and/or redox potential). Charge regulation during ET has never been measured for proteins because few tools exist to measure the net charge of a folded protein in solution at different oxidation states. Herein, we used a niche analytical tool (protein charge ladders analyzed with capillary electrophoresis) to determine that the net charges of myoglobin, cytochrome c, and azurin change by 0.62+/-0.06, 1.19+/-0.02, and 0.51+/-0.04 units upon single ET. Computational analysis predicts that these fluctuations in charge arise from changes in the pKa values of multiple non-coordinating residues (predominantly histidine) that involve between 0.42-0.90 eV. These results suggest that ionizable residues can tune the reactivity of redox centers by regulating the net charge of the entire protein-cofactor-solvent complex.

AB - BACKGROUND: Postoperative chemoradiotherapy (CRT) is considered standard of care in patients with locally advanced head and neck cancer with positive margins and/or extracapsular extension (ECE). METHODS: The National Cancer Data Base (NCDB) was queried to identify patients with squamous cell carcinoma of the head and neck with stages III to IVB disease or with positive margins and/or ECE diagnosed between 2004 and 2012 receiving postoperative radiotherapy (RT). Using univariable and multivariable logistic and Cox regression, we assessed for predictors of CRT use and covariables impacting overall survival (OS), including in a propensity-matched subset. RESULTS: Of 12 224 patients, 67.1% with positive margins and/or ECE received CRT as well as 54.0% without positive margins and/or ECE. The 5-year OS was 61.6% for RT alone versus 67.4% for CRT. In the propensity matched cohort, OS benefit persisted with CRT, including in a subset with positive margins and/or ECE but not without. CONCLUSION: Postoperative CRT seems underutilized with positive margins and/or ECE and overutilized without positive margins and/or ECE. The CRT was associated with improved OS but the benefit persisted only in the subset with positive margins and/or ECE. PMID- 29451962 TI - Nucleopeptide Assemblies Selectively Sequester ATP in Cancer Cells to Increase the Efficacy of Doxorubicin. AB - Herein, we report that assemblies of nucleopeptides selectively sequester ATP in complex conditions (for example, serum and cytosol). We developed assemblies of nucleopeptides that selectively sequester ATP over ADP. Counteracting enzymes interconvert ATP and ADP to modulate the nanostructures formed by the nucleopeptides and the nucleotides. The nucleopeptides, sequestering ATP effectively in cells, slow down efflux pumps in multidrug-resistant cancer cells, thus boosting the efficacy of doxorubicin, an anticancer drug. Investigation of 11 nucleopeptides (including d- and l-enantiomers) yields five more nucleopeptides that differentiate ATP and ADP through either precipitation or gelation. As the first example of assemblies of nucleopeptides that interact with ATP and disrupt intracellular ATP dynamics, this work illustrates the use of supramolecular assemblies to interact with small and essential biological molecules for controlling cell behavior. PMID- 29451963 TI - Aortic valve stenosis and aortic diameters determine the extent of increased wall shear stress in bicuspid aortic valve disease. AB - BACKGROUND: Use of 4-dimensional flow magnetic resonance imaging (4D-flow MRI) derived wall shear stress (WSS) heat maps enables identification of regions in the ascending aorta with increased WSS. These regions are subject to dysregulation of the extracellular matrix and elastic fiber degeneration, which is associated with aortic dilatation and dissection. PURPOSE: To evaluate the effect of the presence of aortic valve stenosis and the aortic diameter on the peak WSS and surface area of increased WSS in the ascending aorta. STUDY TYPE: Prospective. SUBJECTS: In all, 48 bicuspid aortic valve (BAV) patients (38.1 +/- 12.4 years) and 25 age- and gender-matched healthy individuals. FIELD STRENGTH/SEQUENCE: Time-resolved 3D phase contrast MRI with three-directional velocity encoding at 3.0T. ASSESSMENT: Peak systolic velocity, WSS, and aortic diameters were assessed in the ascending aorta and 3D heat maps were used to identify regions with elevated WSS. STATISTICAL TESTS: Comparisons between groups were performed by t-tests. Correlations were investigated by univariate and multivariate regression analysis. RESULTS: Elevated WSS was present in 15 +/- 11% (range; 1-35%) of the surface area of the ascending aorta of BAV patients with aortic valve stenosis (AS) (n = 10) and in 6 +/- 8% (range; 0-31%) of the ascending aorta of BAV patients without AS (P = 0.005). The mid-ascending aortic diameter negatively correlated with the peak ascending aortic WSS (R = -0.413, P = 0.004) and the surface area of elevated WSS (R = -0.419, P = 0.003). Multivariate linear regression analysis yielded that the height of peak WSS and the amount of elevated WSS depended individually on the presence of aortic valve stenosis and the diameter of the ascending aorta. DATA CONCLUSION: The extent of increased WSS in the ascending aorta of BAV patients depends on the presence of aortic valve stenosis and aortic dilatation and is most pronounced in the presence of AS and a nondilated ascending aorta.

AB - OBJECTIVES: This study compared and assessed long-term voice outcomes when thyroidectomy-related unilateral vocal fold paralysis (VFP) was managed using injection laryngoplasty (IL) and recurrent laryngeal nerve reinnervation (RLNR). STUDY DESIGN: Prospective clinical study. METHODS: A prospective clinical trial was performed from March 2005 to January 2016 at Soonchunhyang University Bucheon Hospital (Bucheon, South Korea). Nineteen patients who underwent ansa cervicalis to RLNR or direct reinnervation, and 43 patients who underwent IL to treat thyroidectomy-related unilateral VFP, were enrolled. RESULTS: All voice parameters exhibited statistically significant improvement 12 months post-IL, which persisted for 24 and 36 months (P < 0.05). However, at 36 months post-IL, some voice parameters had deteriorated relative to the values at 24 months post IL. After RLNR, all voice parameters exhibited statistically significant improvement after 12 months, and the improvements remained stable until 36 months postsurgery without deterioration of voice parameters (P < 0.05). At 36 months, RLNR provided better voice results than IL (P < 0.05). CONCLUSION: Both RLNR and IL yielded statistically significant voice improvements at 36 months postoperatively. However, after 36 months, RLNR provided better results than IL. LEVEL OF EVIDENCE: 3. Laryngoscope, 1893-1897, 2018. PMID- 29451965 TI - Pazopanib effective for bevacizumab-unresponsive epistaxis in hereditary hemorrhagic telangiectasia. AB - Hereditary hemorrhagic telangiectasia (HHT) most commonly manifests with nasal mucosal telangiectasias, and vascular endothelial growth factor (VEGF) plays a significant role in this angiodysplasia. We describe a patient with HHT with epistaxis recalcitrant to several endonasal procedures and six cycles of intravenous bevacizumab, for which he was dependent on iron infusions and packed red blood cells transfusions. He then started pazopanib at 100 mg with dramatic improvements in epistaxis and normalization of hemoglobin and iron levels, without replenishment needs for 12 months. This is the first report on the efficacy of pazopanib with high selectivity for abrogating VEGF receptor-2 signaling in HHT, and needs to be explored further. Laryngoscope, 128:2234-2236, 2018.

PMID- 29451968 TI - Establishment of Mimosa biuncifera (Fabaceae) inoculated with arbuscular mycorrhizal fungi in greenhouse and field drought conditions. AB - Mexico is dominated by arid or semi-arid ecosystems, predominantly characterized as xeric shrublands.These areas are frequently deteriorated due to agriculture or over-grazing by livestock (sheep and goats).The vegetation type mainly consists of thorny plant species, and among these, the dominant one in overgrazedareas is catclaw (Mimosa biuncifera). This is a nurse plant that facilitates establishment of other vegetation andpromotes plant succession. Catclaw plants form a mutualistic association with arbuscular mycorrhizal fungi(AMF), which improves uptake of nutrients and water. The objective of this study was to determine the effectof inoculating catclaw plants with native AMF and starting their growth under a low water availability treatmentin a greenhouse, and later transplanting them to field conditions of drought and deterioration. Field plants wereevaluated according to their survivorship and growth. The seeds of catclaw plants and soil with AMF sporeswere collected in the Mezquital Valley of Hidalgo State, in Central Mexico. Seedlings were grown in individualpots in a greenhouse. The experimental design consisted of two levels of pot irrigation, wet (W) and dry (D),as well as the presence (M+) or absence (M-) of AMF inoculum, with 20 replicates for each treatment. The followingplant parameters were recorded every week: height, number of leaves and pinnae, and mean diameterof coverage. After 20 weeks in the greenhouse, determination was made of fresh and dry biomass, relativegrowth rate (RGR), root/shoot ratio, real evapotranspiration (RET), water use efficiency (WUE), and percentageof mycorrhizal colonization. The remaining plants growing under the dry treatment (M+ and M-) were thentransplanted to a semi-arid locality in the Mezquital Valley. During one year, monthly records were kept of theirheight, number of leaves, mean diameter of coverage and survival. Results showed that compared to greenhouseplants under other treatments, those under the wet mycorrhizal (WM+) treatment were taller, had more pinnae,and were characterized by greater coverage, faster RGR, and greater fresh and dry biomass. Moreover, inoculatedplants (WM+ and DM+) showed higher WUE than those uninoculated (WM- and DM-, respectively).After one year in field conditions, there was a higher survival rate for previously inoculated versus uninoculatedplants. Hence, mycorrhization of M. biuncifera with native AMF inoculum increased plant efficiency in biomassproduction, thus favoring establishment and survival in field conditions. We concluded that inoculation ofcatclaw plants is recommendable for revegetation programs in deteriorated semi arid zones. PMID- 29451969 TI - The inhibitory effect of a non-yessotoxin-producing dinoflagellate, Lingulodinium polyedrum (Stein) Dodge, towards Vibrio vulnificus and Staphylococcus aureus. AB - The increased bacterial resistance to antibiotics has caused global concern, prompting the search fornew compounds. Because of their abundance and diversity, marine phytoplankton are an important potentialsource of such compounds. Research on dinoflagellates has led to the discovery of inhibitors of bacterial growth.The marine dinoflagellate Lingulodinium polyedrum blooms in different regions of the world, including Mexico,and is also known to regulate the growth of other species in coastal waters. Here, we investigated the taxonomyof this dinoflagellate and characterized the ability of its extracts to inhibit the growth of two bacteria of medicalimportance (Vibrio vulnificus and Staphylococcus aureus). Taxonomic characterization was performed byPCR and gene amplification of ITS, and confirmed that the species isolated off the Pacific coast of Mexico wasL. polyedrum. To prove the inhibitory effect of L. polyedrum extracts, cultures were harvested by centrifugation.Pellets from three cellular abundances were extracted with water, methanol, hexane and chloroform. Theexperiments on V. vulnificus showed a high growth inhibition for the four extracts, ranging from 77 to 98 %.Surprisingly, the growth inhibition was lower when the extracts originated from a higher L. polyedrum cell abundance,ranging from 0 to 34 %. For S. aureus, the growth inhibition was also high, but not statistically differentfor all extracts and cell abundances, ranging from 62 to 99 %. This study obtained promising results for futurepharmacological applications. Our Mexican strain of L. polyedrum did not produce any detectable yessotoxins. PMID- 29451967 TI - Cognitive behavioral therapy for anxiety and related disorders: A meta-analysis of randomized placebo-controlled trials. AB - The purpose of this study was to examine the efficacy of cognitive behavioral therapy (CBT) for anxiety-related disorders based on randomized placebo controlled trials. We included 41 studies that randomly assigned patients (N = 2,843) with acute stress disorder, generalized anxiety disorder (GAD), obsessive compulsive disorder (OCD), panic disorder (PD), posttraumatic stress disorder (PTSD), or social anxiety disorder (SAD) to CBT or a psychological or pill placebo condition. Findings demonstrated moderate placebo-controlled effects of CBT on target disorder symptoms (Hedges' g = 0.56), and small to moderate effects on other anxiety symptoms (Hedges' g = 0.38), depression (Hedges' g = 0.31), and quality of life (Hedges' g = 0.30). Response rates in CBT compared to placebo were associated with an odds ratio of 2.97. Effects on the target disorder were significantly stronger for completer samples than intent-to-treat samples, and for individuals compared to group CBT in SAD and PTSD studies. Large effect sizes were found for OCD, GAD, and acute stress disorder, and small to moderate effect sizes were found for PTSD, SAD, and PD. In PTSD studies, dropout rates were greater in CBT (29.0%) compared to placebo (17.2%), but no difference in dropout was found across other disorders. Interventions primarily using exposure strategies had larger effect sizes than those using cognitive or cognitive and behavioral techniques, though this difference did not reach significance. Findings demonstrate that CBT is a moderately efficacious treatment for anxiety disorders when compared to placebo. More effective treatments are especially needed for PTSD, SAD, and PD.

Here we reply to Monge Najera's comment on the use of the terms ensemble and assemblage, we argue for the use of the words ensamble and ensamblaje in Spanish. In addition, both terms have a proper place in ecology and we provide a case for their use in proper ecological context. PMID- 29451971 TI - [Evaluation of the growth of Callinectes sapidus (Decapoda: Portunidae) by the use of lengthbased methods based on size in Tamaulipas, Mexico]. AB - The capture blue crab (Callinectes sapidus) is one of the major fisheries of the state of Tamaulipas, Mexico; both in volume and selling price, as well as employment generation, but there is little information on its biological characteristics. The aim of this study was to evaluate the growth parameters of the blue crab, establishing the most appropriate method. We estimated the length frequency of 17 814 crabs from commercial catch of thirteen locations, including four coastal lagoons. The lagoons were El Barril, Madre, Morales and San Andres from Tamaulipas, State. Growth parameters were evaluated using indirect methods ELEFAN, PROJMAT and SLCA in combination with the jackknife technique to establish the uncertainty of estimates inherent in each method. The growth parameters Linfinity and k were consolidated for purposes of comparison with the growth index phi prime (Phi'). With a mode of 110 mm, the interval carapace length varied between 60 and 205 mm. The values of the growth parameters varied according to the method used. Using SLCA, Linfinity varied between 259 and 260 mm and k ranged between 0.749 and 0.750 /year; with PROJMAT, Linfinity recorded values between 205 and 260 mm, k fluctuated between 0.550 and 0.740/year, and with ELEFAN, Linfinity ranged between 156 and 215 mm and k varied between 0.479 and 0.848/year. Estimates by jackknife detected no variability in Phi' between locations and significant differences between methods. The ranges of values of Phi' and PROJMAT estimated SLCA (4.70 to 4.71 and 4.66 to 4.70, respectively) were in the range reported in the literature (4.201-4.798), while lower values ELEFAN contributed significantly (3.87 to 4.27). The SLCA and PROJMAT methods in combination with the jackknife technique, proved to be the most suitable to estimate the growth parameters of C. sapidus. PMID- 29451972 TI - Understanding trophic relationships among Caribbean sea urchins. AB - The species Echinometra lucunter, Echinometra viridis, Lytechinus variegatus, Tripneustes ventricosus,and Diadema antillarum are the most common sea urchins of littoral habitats in the Caribbean. T.ventricosus and L. variegatus are associated with seagrass beds, while the other three species usually inhabithardground substrates. Food preferences of these species are well documented and they are commonly acceptedas being primarily herbivorous omnivorous; nevertheless, few of them have previously been characterized isotopically.We used this approach for assessing the isotopic characterization of five echinoids. We established thetrophic position of two groups of co-occurring species and quantified the contribution of food resources in thediet of Echinometra lucunter, considered the most common sea urchin in the Caribbean region. The species T.ventricosus and D. antillarum showed the highest values of delta15N. Sea urchins exhibited similar values of delta13Cvarying from -11.6 +/- 0.63 to -10.4 +/- 0.99%. The echinoid E. lucunter displayed the lowest values of carbon,from -15.40 +/- 0.76%. Significant differences among species were found for delta15N and delta13C. Seaweed communitiesexhibited no differences among sites for overall delta15N (F= 1.300, df= 3, p= 0.301), but we found spatialdifferences for delta13C (F= 7.410, df= 3, p= 0.001). The ellipse-based metrics of niche width analysis found thatthe hardground biotope species (D. antillarum, E. lucunter, and E. viridis) did not overlap each other. Similarresults were obtained for the co-occurring species of the seagrass biotope; however, the distance between thesespecies was closer than that of the hardground biotope species. The Bayesian mixing models run for E. lucunterat all four localities found differences in food resources contribution. The algae D. menstrualis, C. crassa andB. triquetrum dominated in CGD; whereas C. nitens, Gracilaria spp., and D. caribaea represented the maincontributor algae to the diet of E. lucunter at LQY. In Culebra Island, no dominance of any particular algae wasdetected in TMD, where six of the eight species exhibited a similar contribution. Similarities in delta15N between D.antillarum and T. ventricosus may hint towards a similar trophic level for these species, although T. ventricosusis widely accepted as an omnivore, while D. antillarum is considered a generalist herbivore. The lack of overlapamong species in the two biotopes seems to indicate a resource partitioning strategy to avoid niche competitionamong co occurring species.

AB - Histochemical techniques today allow you to select areas of tissue and generate reliable information on the distribution of energy reserves in bivalve molluscs during their life cycle. The main objective of this study was to describe and relate the gametogenic cycle with the availability of energy reserves and the environmental parameters. For this, we sampled and examined the gonads and digestive glands (DG) of 15 individuals collected monthly during April 2012 and February 2013. We processed and analyzed the samples by standard histological and histochemical light microscopy techniques. Our results showed that for the gametogenic cycle, the monthly proportion of mature organisms was higher for males, between August (40 %) and November (53 %), while the females tend to have a shorter synchronized cycle and release of gametes in September (67 %) and October (60 %). The intense spawning periods in both sexes was the same (October to January). Between the periods April-August 2012 and January-February 2013, we observed the highest values of IGl and glucide index (instead, a decrease was observed in September, reaching minimumvalues during the period October December). Besides, the maximum values of IL, lipid index, were observed in April 2012 and February-2013, with an intermediate value in August-2013. The results indicated that the reserves of the GD have a pattern of mobilization inversely related to the proliferation of gametes in both sexes; this was directly linked to the availability of nutrients such as chlorophyll a and the organic seston. PMID- 29451974 TI - [Regenerative morphological traits in a woody species community in Tumbesian tropical dry forest]. AB - The study of functional morphological traits enables us to know fundamental aspects of the dynamicsof plant communities in local and global habitats. Regenerative morphological traits play an important role indefining plant history and ecological behavior. Seed and fruit characteristics determine to a large extent the patternsfor dispersal, germination, establishment and seedling recruitment a given species exhibits on its naturalhabitat. Despite their prominent role, seed and fruit traits have been poorly studied at the community level ofwoody plant species in neo-tropical dry forests. In the present study we aimed at i) evaluate the functional roleof morphological traits of seeds, fruits and embryo in woody plant species; ii) determine which are the morphologicalpatterns present in seeds collected from the community of woody species that occur in neo-tropicaldry forests; and iii) compare woody plant species seed mass values comparatively between neo-tropical dry andtropical forests. To do so, mature seeds were collected from 79 plant species that occur in the Tumbesian forest ofSouthwest Ecuador. The studied species included the 42 and 37 most representative tree and shrubbery species ofthe Tumbesian forest respectively. A total of 18 morphological traits (seven quantitative and 11 qualitative) weremeasured and evaluated in the seeds, fruits and embryos of the selected species, and we compared the seeds masswith other forest types. Our results showed a huge heterogeneity among traits values in the studied species. Seedmass, volume and number were the traits that vary the most at the community level, i.e. seed length ranged from1.3 to 39 mm, and seed width from 0.6 to 25 mm. Only six embryo types were found among the 79 plant species.In 40 % of the cases, fully developed inverted embryos with large and thick cotyledons to store considerableamount of nutrients were recorded. We concluded that highly variable and functionally complementary morphologicaltraits occur among the studied woody plants of the Tumbesian dry forest. The latter favors a plethora ofbehavioral mechanisms to coexist among woody species of the dry forest in response to the environmental stressthat is typical of arid areas. PMID- 29451975 TI - Using a jumping spider fauna inventory (Araneae: Salticidae) as an indicator of their taxonomic diversity in Misiones, Argentina. AB - Faunistic studies, with a taxonomically complete inventory of species, provide an important sourceof quantitative compiled information for several and specific regions. This information can be used in diversityanalysis and has great potential in setting conservation priorities. In this study, I used the relatively well knownsalticid spider fauna of Misiones to generate Clarke & Warwick taxonomic diversity indices. For this, informationof three ecoregional salticid diversities was obtained and analyzed between Upper Parana Atlantic Forest(UPAF), Araucaria Moist Forest (AMF), and Southern Cone Mesopotamian Savanna (SCMS). Results showeddifferences between the three ecoregions of the province, mainly Southern savannas regarding the forests ofNorthern Misiones. Most species were registered in UPAF followed by AMF, however the alpha-taxonomic diversityof salticids was higher in SCMS than in UPAF and AMF. The beta-taxonomic diversity showed that the proportionsof shared species between SCMS and UPAF (or and AMF) were the lowest. The high taxonomic dissimilarityamong ecoregions is an indication that the three assemblages are distant, showing a variation in their vegetationhabitat and/or bioclimatic characteristics as a possible reason. The need to expand with new samples in subsampledor underexplored areas of Misiones remains essential, however this study contributes to informationabout biodiversity levels of salticid fauna in three ecoregions of Northeast Argentina, and will provide referencedata for future studies for management plans. PMID- 29451976 TI - Early harvest increases post-harvest physiological quality of Araucaria angustifolia (Araucariaceae) seeds. AB - Araucaria angustifolia is a conifer native to Brazil and is an endangered species. Since this speciesseeds have a short period of viability, its vulnerability is higher. Thus the aim of this study was to evaluate thephysiological quality of A. angustifolia seeds during the development and post storage periods. For this, conesof A. angustifolia were collected from a natural population in Curitibanos, Santa Catarina, Brazil, in March,April, May and June 2012. The collected seeds were classified into developmental stages of cotyledonary, I, IIand III according to the month of collection; a total of 10 cones were collected for each stage. Seeds were storedin a refrigerator for 60 and 120 days, and were submitted to a chamber germination test (25 degrees C photoperiod 12h). Additionally, seeds were tested for moisture content (105 degrees C for 24 hours), tetrazolium (0.1 % for 1 hour)and vigor (electric conductivity [75 mL distilled water at 25 degrees C], germination speed index, and shoot and rootlength). Our results showed that during seed development, moisture content decreased from the cotyledonarystage (66.54 %) to stage III (49.69 %), and vigor increased in the last stage. During storage, moisture contentat cotyledonary stage and stage I was stable. On the other hand, stored seeds exhibited a decrease in moisturecontent after 120 days at stages II and III. Physiological quality at the cotyledonary stage resulted in an increasedgermination rate of 86 % and 93 % after 60 and 120 days of storage, respectively; unlike stages II and IIIexhibited a decrease in seed viability and vigor after storage. Electrical conductivity was higher for fresh seedsat the cotyledonary stage, than for those stored for 60 and 120 days. However, in other stages, released leachatecontent after 120 days of storage, increased with the advance of the collection period. Germination speed indexand shoot and root lengths after storage were highest for seeds at the cotyledonary stage and stage I; unlikestages II and III which had short root and shoot lengths during storage. Thus, the maintenance of seed moisturecontent during storage was variable and dependent on the period of collection. Furthermore, the physiologicalquality differed among earlier and later stages. Early collection favored seed physiological quality, and may bea strategy for better conservation of A. angustifolia seeds.

AB - The distribution of carbon in "Blue Carbon" ecosystems such as mangroves is little known,when compared with the highly known terrestrial forests, despite its particular and recognized high productivityand carbon storage capacity. The objective of this study was to analyze the above ground biomass (AGB) ofthe species Rhizophora mangle and Avicennia germinans from the Marine Protected Area of Distrito de ManejoIntegrado (DMI), Cispata-Tinajones-La Balsa, Caribbean Colombian coast. With official authorization, weharvested and studied 30 individuals of each species, and built allometric models in order to estimate AGB.Our AGB results indicated that the studied mangrove forests of the DMI Colombian Caribbean was of 129.69+/- 20.24 Mg/ha, equivalent to 64.85 +/- 10.12 MgC/ha. The DMI has an area of 8 570.9 ha in mangrove forests,and we estimated that the total carbon potential stored was about 555 795.93 Mg C. The equations generated inthis study can be considered as an alternative for the assessment of carbon stocks in AGB of mangrove forestsin Colombia; as other available AGB allometric models do not discriminate mangrove forests, despite beingparticular ecosystems. They can be used for analysis at a more detailed scale and are considered useful to determinethe carbon storage potential of mangrove forests, as a country alternative to support forest conservation andemission reduction strategies. In general, the potential of carbon storage from Colombian Caribbean mangroveforests is important and could promote the country leadership of the "blue carbon" stored.

AB - Since 1983, San Pedro Bay in the Philippines had been reported to be the site of episodic Pyrodinium bahamense var. compressum blooms that caused paralytic shellfish poisoning in its nearby coastal communities. This bay is also subjected to numerous storms; the strongest was super typhoon Haiyan in November 8, 2013. For the first time, the seasonal dynamics of potentially toxic and harmful phytoplankton in this bay is elucidated. This is also the first record of a bloom of the cyanobacteria, Trichodesmium erythraeum that reached 70 000 colonies/L in April 2013 in this area. There were other 19 potentially toxic and harmful phytoplankton encountered during the sampling period. These consisted of a haptophyte, Phaeocystis globosa, the diatom Pseudo-nitzschia and 17 dinoflagellates. Seven of these harmful algae had densities high enough to be traced through time. Normally, diatoms abound during the dry season. But Pseudo nitzschia increased in abundance during the wet season of 2012 and 2013. The dinoflagellates and Phaeocystis globosa behaved as expected and exhibited a relative increase in cell density during the rainy season of both years too. High nutrient availability during this season must have influenced the behavior of the phytoplankton despite differences in temperature and light intensity among seasons. Other notable but rare harmful species found only in plankton net tows during the study were Pyrodinium bahamense var. compressum, Alexandrium tamiyavanichii, Cochlodinium polykrikoides, and Noctiluca scintillans. PMID- 29451979 TI - Neat Protein-Polymer Surfactant Bioconjugates as Universal Solvents. AB - Solvents, particularly those having low volatility, are of great interest for the biocatalytic synthesis of utility chemicals and fuels. We show novel and universal solvent-like properties of a neat and water-less polymer surfactant bovine serum albumin (BSA) conjugated material (WL-PS pBSA). This highly viscous, nonvolatile material behaves as a liquid above its solid-liquid transition temperature (~25-27 degrees C) and can be used as a solvent for variety of completely dry solutes of different sizes and surface chemistries. We show using a combination of optical microscopy and steady -state and time-resolved fluorescence spectroscopy that dry and powdered dyes (hydrophobic Coumarin 153 (C153)), enzymes (alpha-chymotrypsin (alpha-Chy)), or even 1 MUm microparticles (diffusion coefficient ca. three orders slower than C153), can be solubilized and completely dispersed in the WL-PS pBSA solvent above 25 degrees C. While C153, irrespective of its mode of addition to WL-PS pBSA, binds similarly to BSA, alpha Chy can be stabilized and activated to perform its hydrolysis function, even at 100 degrees C. This work therefore provides insights into the form of universal solvent characteristic property for this new class of nonaqueous, nonvolatile, biodegradable protein-polymer surfactant-based conjugated materials and suggests potential new avenues that can have a huge impact on biocatalysis, bionanotechnology, drug delivery, and other applications.

AB - Synthetic lethality is a molecular-targeted therapy for selective killing of cancer cells. We exploited a lethal interaction between superoxide dismutase 1 inhibition and Bloom syndrome gene product (BLM) defect for the treatment of colorectal cancer (CRC) cells (HCT 116) with a customized lung cancer screen-1 loaded nanocarrier (LCS-1-NC). The drug LCS-1 has poor aqueous solubility. To overcome its limitations, a customized NC, composed of a magnetite core coated with three polymeric shells, namely, aminocellulose (AC), branched poly(amidoamine), and paraben-PEG, was developed for encapsulating LCS-1. Encapsulation efficiency and drug loading were found to be 74% and 8.2%, respectively. LCS-1-NC exhibited sustained release, with ~85% of drug release in 24 h. Blank NC (0.5 mg/mL) exhibited cytocompatibility toward normal cells, mainly due to the AC layer. LCS-1-NC demonstrated high killing selectivity (104 times) toward BLM-deficient HCT 116 cells over BLM-proficient HCT 116 cells. Due to enhanced efficacy of the drug using NC, the sensitivity difference for BLM deficient cells increased to 1.7 times in comparison to that with free LCS-1. LCS 1-NC induced persistent DNA damage and apoptosis, which demonstrates that LCS-1 NC effectively and preferentially killed BLM-deficient CRC cells. This is the first report on the development of a potential drug carrier to improve the therapeutic efficacy of LCS-1 for specific killing of CRC cells having BLM defects. PMID- 29451981 TI - High Performance Anion Exchange and Hydrophilic Interaction Liquid Chromatography Approaches for Comprehensive Mass Spectrometry-Based Characterization of the N Glycome of a Recombinant Human Erythropoietin. AB - Comprehensive characterization of the N-glycome of a therapeutic is challenging because glycans may harbor numerous modifications (e.g., phosphorylation, sulfation, sialic acids with possible O-acetylation). The current report presents a comparison of two chromatographic platforms for the comprehensive characterization of a recombinant human erythropoietin (rhEPO) N-glycome. The two platforms include a common workflow based on 2-AB-derivatization and hydrophilic interaction chromatography (HILIC) and a native N-linked glycan workflow employing high performance anion exchange (HPAE) chromatography. Both platforms were coupled to an Orbitrap mass spectrometer, and data dependent HCD fragmentation allowed confident structural elucidation of the glycans. Each platform identified glycans not revealed by the other, and both exhibited strengths and weaknesses. The reductive amination based HILIC workflow provided better throughput and sensitivity, had good isomer resolution, and revealed the presence of O-acetylated sialic acids. However, it exhibited poor performance toward phosphorylated glycans and did not reveal the presence of sulfated glycans. Furthermore, reductive amination introduced dehydration artifacts and modified the glycosylation profile in the rhEPO glycome. Conversely, HPAE provided unbiased charge classification (sialylation levels), improved isomer resolution, and revealed multiple phosphorylated and sulfated structures, but delivered lower throughput, had artifact peaks due to epimer formation, and loss of sialic acid O-acetylation. The MS2 based identification of phosphorylated and sulfated glycans was not possible in HILIC mode due to their poor solubility caused by the high acetonitrile concentrations employed at the beginning of the gradient. After analyzing the glycome by both approaches and determining the glycans present, a glycan library was created for site specific glycopeptide analyses. Glycopeptide analyses confirmed all the compositions annotated by the combined use of 2-AB- and native glycan workflows and provided site specific location of the glycans. These two platforms were complementary and in combination delivered a more thorough and comprehensive characterization of the rhEPO N-glycome, supporting regulatory conformance for the pharmaceutical industry. PMID- 29451982 TI - Photodissociation of the Cyclopentadienyl Radical at 248 nm. AB - The photodissociation of jet-cooled cyclopentadienyl radicals, c-C5H5, at 248 nm was studied using photofragment translational spectroscopy. Two dissociation channels were observed: H + C5H4 and C3H3 + C2H2. The C5H4 fragment was identified as ethynylallene by its ionization energy. The translational energy distribution determined for each channel suggests that both dissociation mechanisms occur via internal conversion to the ground electronic state followed by intramolecular vibrational redistribution and dissociation. The experimental branching ratio and RRKM (Rice-Ramsperger-Kassel-Marcus) calculations favor the formation of C3H3 + C2H2 over the H-atom loss channel. The RRKM calculations also support the observation of ethynylallene as the dominant C5H4 product isomer. PMID- 29451983 TI - Reinforcing Mucus Barrier Properties with Low Molar Mass Chitosans. AB - The mucus gel covers the wet epithelia that forms the inner lining of the body. It constitutes our first line of defense protecting the body from infections and other deleterious molecules. Failure of the mucus barrier can lead to the inflammation of the mucosa such as in inflammatory bowel diseases. Unfortunately, there are no effective strategies that reinforce the mucus barrier properties to recover or enhance its ability to protect the epithelium. Herein, we describe a mucus engineering approach that addresses this issue where we physically cross link the mucus gel with low molar mass chitosan variants to reinforce its barrier functions. We tested the effect of these chitosans on mucus using in-lab purified porcine gastric mucins, which mimic the native properties of mucus, and on mucus secreting HT29-MTX epithelial cell cultures. We found that the lowest molar mass chitosan variant (degree of polymerization of 8) diffuses deep into the mucus gels while physically cross-linking the mucin polymers, whereas the higher molar mass chitosan variants (degree of polymerization of 52 and 100) interact only superficially. The complexation resulted in a tighter mucin polymer mesh that slowed the diffusion of dextran polymers and of the cholera toxin B subunit protein through the mucus gels. These results uncover a new use for low molar mass mucoadhesive polymers such as chitosans as noncytotoxic mucosal barrier enhancers that could be valuable in the prevention and treatment of mucosal diseases. PMID- 29451984 TI - Two-Component Ferritin Nanoparticles for Multimerization of Diverse Trimeric Antigens. AB - Antigen multimerization on a nanoparticle can result in improved neutralizing antibody responses. A platform that has been successfully used for displaying antigens from a number of different viruses is ferritin, a self-assembling protein nanoparticle that allows the attachment of multiple copies (24 monomers or 8 trimers) of a single antigen. Here, we design two-component ferritin variants that allow the attachment of two different antigens on a single particle in a defined ratio and geometric pattern. The two-component ferritin was specifically designed for trimeric antigens, accepting four trimers per particle for each antigen, and was tested with antigens derived from HIV-1 envelope (Env) and influenza hemagglutinin (HA). Particle formation and the presence of native like antigen conformation were confirmed through negative-stain electron microscopy and antibody-antigen binding analysis. Immunizations in guinea pigs with two-component ferritin particles, displaying diverse Env, HA, or both antigens, elicited neutralizing antibody responses against the respective viruses. The results provide proof-of-principle for the self-assembly of a two component nanoparticle as a general technology for multimeric presentation of trimeric antigens. PMID- 29451986 TI - Treatment of striae distensae: An evidence-based approach. AB - Striae distensae (SD), otherwise known as "stretchmarks," are a common presenting complaint, particularly in young healthy women. SD are hypothesized to form in a patient when the cross-linked collagen is "overstretched" and rupture of this collagen matrix causes the striae. Thus, many treatments work by increasing collagen synthesis. This review critically appraises the evidence to date for the treatment of SD, including both energy-based devices and topical treatments. PMID- 29451985 TI - A comparison of barriers to accessing services for mental and physical health conditions in a sample of rural Australian adults. AB - INTRODUCTION: The prevalence of chronic disease, mortality and suicide rates is higher in rural Australia than in urban centres. Understanding rural Australians' barriers to accessing health services requires urgent attention. The purpose of this study was to compare barriers to help-seeking for physical and mental health issues among rural South Australian adults. METHODS: A total of 409 people from three rural and remote regions in South Australia completed a computer-assisted telephone interview. They were presented a physical or mental health scenario and rated the extent to which barriers would prevent them from seeking help for that condition. Responses ranged from 1 ('strongly disagree') to 5 ('strongly agree') and were averaged to form domain scores (higher scores representing stronger barriers to seeking support), in addition to being examined at the item level. RESULTS: Men reported higher barriers for the mental compared with physical health scenario across four domains ('need for control and self-reliance', 'minimising the problem, resignation and normalisation', 'privacy' and 'emotional control'). Women reported higher barriers for the mental compared to physical health scenario in two domains ('need for control and self-reliance' and 'privacy'). Both men and women endorsed many items in the mental health context (eg 'I don't like feeling controlled by other people', 'I wouldn't want to overreact to a problem that wasn't serious', 'Problems like this are part of life; they're just something you have to deal with', 'I'd prefer just to put up with it rather than dwell on my problems', 'Privacy is important to me, and I don't want other people to know about my problems' and 'I don't like to get emotional about things') but in the physical health context, barriers were endorsed only by men (eg 'I wouldn't want to overreact to a problem that wasn't serious',' I'd prefer just to put up with it rather than dwell on my problems', 'Problems like this are part of life; they're just something you have to deal with', 'I like to make my own decisions and not be too influenced by others'). CONCLUSIONS: Both rural men and rural women report more barriers to help seeking for mental health issues than physical health issues across a range of domains. There is a need to educate the current and future rural health and mental health workforce about these barriers and to encourage them to test evidence-based strategies to address them, in particular to facilitate more widespread mental health help-seeking in rural Australia. PMID- 29451987 TI - Association of adiponectin/leptin ratio with carbohydrate and lipid metabolism parameters in HIV-infected patients during antiretroviral therapy. AB - BACKGROUND: Adiponectin and leptin are adipose tissue hormones that regulate important lipid and glucose metabolic pathways. Our objective was to evaluate the interplay of these hormones described by the adiponectin/leptin ratio (ALR) in correlation to lipid and carbohydrate metabolism parameters in nondiabetic HIV infected patients during antiretroviral therapy (ART). MATERIALS AND METHODS: We enrolled consecutive nondiabetic patients with confirmed HIV infection, undergoing stable ART regimens for at least six months. Blood samples were collected and tested for immunological and virological parameters, adiponectin and leptin, fasting insulin, fasting plasma glucose, fasting triglycerides, total cholesterol, LDL cholesterol, and HDL cholesterol. ALR was computed for each patient. Resistance to insulin was assessed by calculating the Quantitative Insulin Sensitivity Check Index (QUICKI). RESULTS: We enrolled 87 HIV-infected persons, with a mean age of 31.7 years (range: 18-65), including 47 men (mean age = 32.8 years) and 40 women (mean age = 30.5 years). The median value of ALR was 6.8 (interquartile range - IQR = 17.1). In male patients, ALR was inversely associated with the serum level of triglycerides (R = 0.285, p = 0.05), total cholesterol (R = 0.326, p = 0.02), and LDL cholesterol (R = 0.298, p = 0.04). Also for the male cohort, an increase in ALR seemed to improve insulin sensitivity (R = 0.323, p = 0.02) and serum HDL cholesterol (R = 0.597, p = 0.01). None of these correlations were observed in HIV-infected women. CONCLUSION: Adiponectin and leptin seem to play important but different gender specific roles in the pathogenesis of lipid and glucose metabolism of HIV infected patients undergoing antiretroviral therapy. ABBREVIATIONS: ALR, adiponectin/leptin ratio; BMI, body mass index; LDL, low-density lipoprotein; HDL, high-density lipoprotein; QUICKI, Quantitative Insulin Sensitivity Check Index. PMID- 29451988 TI - Results of Nailfold Capillaroscopy in Patients with Normal-Tension Glaucoma. AB - : The aim of the study was to evaluate the results of nailfold videocapillaroscopic examination in patients with normal-tension glaucoma (NTG) in comparison to age-matched individuals without glaucoma and young healthy volunteers and to assess the relation between the results of this examination with clinical status in NTG group. MATERIAL AND METHODS: The studied group consisted of 188 patients: 80 patients with NTG and 2 control groups (58 young healthy and 50 age-matched volunteers). The nailfold videocapillaroscopy (NVC) was performed in all participants. The results of every NVC were qualified as a normal or abnormal pattern. In the NTG group, ophthalmic examination was performed and medical history regarding glaucoma, chronic general disorders, and vascular risk factors was recorded. RESULTS: In the NTG group, an abnormal NVC pattern was more common than in young controls (p = 0.0008). Microbleedings were present more frequently in NTG patients (p = 0.0365). Enlargement of capillaries (p = 0.0006) and branching capillaries (p = 0.0221) were more frequent in the NTG group compared to age-matched controls. Maximal intraocular pressure was higher in NTG patients with abnormal NVC pattern than with normal NVC (p = 0.0000). Disc hemorrhages were more frequently observed in patients with abnormal NVC pattern (p = 0.0313). Presence of paracentral scotoma was associated with abnormal NVC pattern (p = 0.0054). CONCLUSIONS: Abnormalities in nailfold capillaroscopy are more frequent in NTG patients. The results of capillaroscopic examination differ in NTG patients according to the profile of ocular and general risk factor. PMID- 29451989 TI - All done procedure by laser in free gingival graft treatment: A case series study. AB - AIM: This case series study evaluated the application of Er;Cr:YSGG laser for a free gingival graft procedure and the effect of low level laser therapy on post surgical pain and wound healing. CASES: 6 cases with mucogingival problems needing free gingival grafts were selected. First, the recipient site was anesthetized and de-epithelialization was done with a Er;Cr:YSGG laser. After tracing the palatal donor site with the laser, the graft was harvested. For root modification of the recipient tooth, conditioning of the dentin was done by the same laser. The inner side of graft was trimmed by the laser before suturing at the recipient site. After final adaptation of the grafts and suturing process, the recipient and donor sites were irradiated by therapeutic laser for reduction of post surgical complications. RESULTS: All patients reported the reduction in pain level after day 2 on donor and recipient site. Also, the wound healing was achieved after 14 days in all cases in donor site. CONCLUSION: According to high surface absorbance, better incision, coagulation and application on both soft and hard tissues, Er;Cr:YSGG laser can be safe, minimally invasive manner and useful for all steps of the free gingival graft procedure. PMID- 29451990 TI - Intellectual efficiency in children and adolescents with spina bifida myelomeningocele and shunted hydrocephalus. AB - We studied the intellectual profiles of 13 Italian children diagnosed with spina bifida myelomeningocele and shunted hydrocephalus (MMC HC) against a control group of children. The results showed that MMC HC group had lower performance in all subtests, four indices, and the FSIQ of the Wechsler Intelligence Scale for Children, forth-edition. The MMC HC group showed flat cognitive profiles between subtests within each index and between four core indices. However, the cognitive abilities that were mostly impaired seemed to be related to visual selective and focused attention, to visual acuity, to visuo-perceptive organization and visuomotor integration and to visual short-term memory. PMID- 29451991 TI - Exogenous ketone salts do not improve cognitive responses after a high-intensity exercise protocol in healthy college-aged males. AB - This study examined the effects of a d-beta-hydroxybutyrate (betaHB) containing beverage on cognitive and performance measures during a bout of repeated Wingates. Fifteen healthy, college-aged males (mean +/- SD; age: 23.1 +/- 2.4 years, height: 165.4 +/- 2.0 cm, mass: 81.4 +/- 9.2 kg) volunteered for the present study. Trial 1 consisted of baseline measures and familiarization for the protocol. During trials 2 and 3, subjects reported to the laboratory, after a 10 h fast, and ingested 11.38 g of betaHB or a placebo (PLA) beverage 30 min before exercise. Participants then completed a cognitive challenge (CC), consisting of a 5-min FitLight response task while cycling. At the cessation of the test, participants then completed four 15-s repeated Wingates with 4 min of rest between, followed by another 5-min CC response task. Blood ketones, glucose, and lactate were measured pre-CC and post-Wingates. betaHB levels were significantly higher compared with PLA (0.53 vs. 0.21 mmol/L), respectively. A significant order effect was observed across trials 2 and 3 for total FitLight misses and hits, regardless of treatment. Further, there were no significant differences among Wingate power output between treatments, although fatigue index was higher in the betaHB group compared with PLA (32.3 vs. 29.4 W/s), respectively. In conclusion, betaHB did not improve high-intensity cycling or cognitive performance measures; however, these findings might be partially explained by the absolute dosing protocol used for betaHB in the present study as opposed to a relative (g/kg) dosing protocol used in previous research. PMID- 29451992 TI - Optical Coherence Tomography Angiography of the Peripapillary Retina in Normal Tension Glaucoma and Chronic Nonarteritic Anterior Ischemic Optic Neuropathy. AB - PURPOSE: To analyze the retinal radial peripapillary capillary (RPC) network in normal-tension glaucoma (NTG) and nonarteritic anterior ischemic optic neuropathy (NAION) eyes using optical coherence tomography angiography (OCTA). MATERIAL AND METHODS: Twenty-two patients with NTG, 22 patients with unilateral chronic NAION, and 23 age-matched controls were enrolled. Patients underwent OCTA to obtain en face angiograms of the peripapillary region. The main outcome measures were as follows: (1) the whole en face image perfusion density (WPD) and (2) the circumpapillary perfusion density (CPD). RESULTS: Mean +/- SD age was 66.3 +/- 7.0 years in the NTG group, 68.1 +/- 4.3 years in the NAION group, and 63.9 +/- 7.0 years in the control group (p > 0.05 for all the comparisons). The visual field mean defect (MD) was worse in patients than in controls (p < 0.0001), but did not differ between NTG and NAION (-9.6 +/- 2.6 dB and -8.2 +/- 2.6 dB, respectively). The WPD was 0.41 +/- 0.04 in the NTG group (p < 0.0001 in comparison with healthy subjects and NAION patients), 0.46 +/- 0.04 in the NAION group (p < 0.0001 in comparison with the control group), and 0.56 +/- 0.03 in the control group. The CPD was significantly reduced in both NTG (0.48 +/- 0.04, p < 0.0001) and NAION eyes (0.52 +/- 0.05, p < 0.0001), after comparison to control eyes (0.59 +/- 0.03). Moreover, the CPD was significantly lower in NTG than in NAION eyes (p = 0.006). CONCLUSIONS: OCTA documented a reduction of the peripapillary perfusion in NTG and unilateral NAION. In presence of similar functional damage, the lower perfusion densities in NTG may indicate greater vascular alterations in chronic compared to acute ischemic optic neuropathies. PMID- 29451994 TI - Stroop Task-Related Brain Activity in Patients With Insomnia: Changes After Cognitive-Behavioral Therapy for Insomnia. AB - OBJECTIVE/BACKGROUND: In the present study, we compared differences in brain activity during the Stroop task between patients with chronic insomnia disorder (CID) and good sleepers (GS). Furthermore, we evaluated changes in Stroop task related brain activity after cognitive-behavioral therapy for insomnia (CBT-I). PARTICIPANTS/METHODS: The final analysis included 21 patients with CID and 25 GS. All participants underwent functional magnetic resonance imaging (fMRI) while performing the color-word Stroop task. CBT-I, consisting of 5 sessions, was administered to 14 patients with CID in the absence of medication. After CBT-I, fMRI was repeated in the patients with CID while performing the same task. Sleep related questionnaires and sleep variables from a sleep diary were also obtained before and after CBT-I. RESULTS: No significant differences in behavioral performance in the Stroop task or task-related brain activation were observed between the CID and GS groups. No changes in behavioral performance or brain activity were found after CBT-I. However, clinical improvement in the Insomnia Severity Index (ISI) score was significantly associated with changes in the Stroop task-related regional blood oxygen level-dependent signals in the left supramarginal gyrus. CONCLUSIONS: Our findings suggest that cognitive impairment in patients with CID was not detectable by the Stroop task or Stroop task-related brain activation on fMRI. Moreover, there was no altered brain activity during the Stroop task after CBT-I. However, the ISI score reflected changes in the neural correlates of cognitive processes in patients with CID after CBT-I. PMID- 29451995 TI - Sex-Dependent Choroidal Thickness Differences in Healthy Adults: A Study Based on Original and Synthesized Data. AB - PURPOSE: The purpose of this study is to determine the influence of sex on choroidal thickness (CT) in healthy adults. METHODS: Healthy Chinese adults were recruited and complete ophthalmic examinations were performed. The choroid was imaged by swept-source optical coherence tomography and the macular CT in Early Treatment Diabetic Retinopathy Study grids was obtained by the intrinsic automated segmentation software. CT in males and females was compared after controlling other factors. All of the published studies in PubMed were systemically tracked, and a syntheses analysis of the combined data of the present study and previous studies was performed to address this issue further. RESULTS: A total of 104 healthy adults were included, of whom 38 (37%) were male and 66 (63%) were female. Older age and longer axial length (AL) each were significantly associated with thinner CT. After controlling for age and AL, the foveal CT and average macular CT were 25.5 MUm (95% CI: 0.5-50.4 MUm) and 22.1 MUm (95% CI: 2.7-41.4 MUm) thicker in men than in women, respectively. Significant differences in CT between males and females were also observed in inner and outer rings after controlling for age and AL (P < 0.05). After strict screening, 15 previously reported studies were determined to be eligible for inclusion. The combination of data collected from 2821 males and 3389 females provided further evidence that the choroid is thicker in males, with a pooled mean difference of 19.5 MUm (95% CI: 11.4 to 27.6) for foveal CT and 14.7 MUm (95% CI: 6.8 to 22.6) for average CT. CONCLUSION: Our study of Chinese subjects, along with the syntheses analysis, strengthens the evidence that CT is greater in males than in females, based on OCT measurements. This observation may be pertinent for the sex disparities in some clinical conditions related to CT. PMID- 29451996 TI - Foveal Avascular Zone Area Changes Analyzed Using OCT Angiography after Successful Rhegmatogenous Retinal Detachment Repair. AB - PURPOSE: To investigate foveal avascular zone (FAZ) area after surgery in patients with rhegmatogenous retinal detachment (RRD) that involved or uninvolved the macula, and to evaluate the correlation between FAZ area and visual outcomes using swept-source optical coherence tomography angiography (OCTA). MATERIALS AND METHODS: This retrospective case-control study included 34 eyes (34 patients) with recent onset RRD that were successfully repaired with a single, uncomplicated surgical procedure (pars plana vitrectomy with gas tamponade). The changes of FAZ area were examined by OCTA after surgery. The unaffected fellow eye was used as a control for additional comparison. RESULTS: Both superficial and deep FAZ area were significantly larger in the macula-off group (superficial: 0.374 +/- 0.112, deep: 0.702 +/- 0.193 mm2) than in the macula-on group (superficial: 0.282 +/- 0.105, deep: 0.543 +/- 0.114 mm2) following surgery. The deep FAZ area was also markedly larger in the macula-off group than in the control group (0.532 +/- 0.124 mm2). Correlation analyses revealed that both superficial (rho = 0.555, P = 0.015) and deep FAZ (rho = 0.616, P = 0.005) areas were negatively correlated with postoperative best-corrected visual acuity in the macula-off RRD group. CONCLUSIONS: The FAZ area enlargement after successful surgical repair in macula-off RRD eyes may indicate that there is an ischemic damage to retinal capillary plexus in fovea. PMID- 29451997 TI - Poly(lactic-co-glycolic) Acid as a Slow-Release Drug-Carrying Matrix for Methotrexate Coated onto Intraocular Lenses to Conquer Posterior Capsule Opacification. AB - PURPOSE: Posterior capsule opacification (PCO) still represents the main long term complication of cataract surgery. Research into pharmacologic PCO prophylaxis is extensive. One promising candidate drug is methotrexate (MTX). Our aim is to determine the in vitro feasibility of MTX-loaded poly(lactic-co glycolic) (PLGA) biomatrices sprayed on intraocular lenses (IOLs) as a drug delivery implant. METHODS: Hydrophilic and hydrophobic acrylic IOLs were spray coated with MTX-loaded PLGA. Unsprayed, solvent only, and solvent-PLGA-sprayed IOLs served as controls. All IOLs were evaluated for their growth-inhibiting properties in an in vitro anterior segment model and the ex vivo human capsular bag. The release kinetics of MTX from the IOLs was determined. The toxicity of MTX on corneal endothelial cells was evaluated by using a dye reduction colorimetric assay. MTX was also used in a scratch assay. RESULTS: MTX-PLGA-IOL showed a significant difference in cell proliferation and migration compared with all controls in the anterior segment model (p < 0.001) and in the human capsular bag model (p = 0.04). No difference in viability was observed on corneal endothelial cells (p = 0.43; p = 0.61). MTX significantly inhibited cells in the scratch assay (p = 0.02). At all measured points, the released MTX dose remained above EC50 and below the toxic dose for the endothelium. CONCLUSIONS: In view of the strong inhibition of PCO in vitro with the lack of toxic effects on a corneal cell line, MTX encapsulating microspheres seem to be a promising method for modifying IOL. PMID- 29451998 TI - Predicting the Integrated Visual Field with Wide-Scan Optical Coherence Tomography in Glaucoma Patients. AB - PURPOSE: This study aimed to calculate a predicted integrated visual field (IVF) based on predicted monocular visual fields (MVFs) derived, with a new method, from wide-scan optical coherence tomography (OCT) data. MATERIALS AND METHODS: Visual field testing used the central (6 * 4) 24 points of the Humphrey Field Analyzer 24-2 program. OCT scans of a corresponding retinal area, centered on the fovea, were divided into a 6 * 4 grid. The thickness of the macular retinal nerve fiber layer (mRNFL), ganglion cell layer + inner plexiform layer (GCIPL), and mRNFL + GCIPL (GCC) was measured in each grid area. Next, a support vector machine was used to create a MVF prediction model, with training data from 101 eyes of 60 glaucoma patients. Then, the prediction model was validated with data from 108 eyes of 54 glaucoma patients, for MVF and IVF. A simulated IVF was created by merging bilateral simulated MVFs. RESULTS: The overall average of the median 95% prediction interval length for the MVF prediction model (measured in dB) was 10.0, 18.3, and 11.3 for the mRNFL, GCIPL, and GCC, respectively. In the validation data, the overall average root mean squared error (dB) between actual and predicted sensitivity for the IVF was 9.6, 10.5, and 9.5 for the mRNFL, GCIPL, and GCC, respectively, in the 24 grid areas. The intraclass correlation coefficient between average actual and predicted IVF was 0.61, 0.44, and 0.59 in the mRNFL, GCIPL, and GCC, respectively, in the 24 grid areas. CONCLUSIONS: We calculated a predicted IVF based on predicted MVFs that were derived, with a new method, from OCT data and validated the accuracy of the calculated IVF. This technique should improve glaucoma management in cases when standard visual field testing is difficult. PMID- 29451999 TI - Evaluation of the Effects of the Occlu-Pad for the Management of Anisometropic Amblyopia in Children. AB - PURPOSE: In recent years, amblyopia treatment device that can be used with both eyes open have been reported. The Occlu-pad is a device that can present images of tablet terminals to one eye only under binocular open conditions. Till date, no study has reported the effectiveness of Occlu-pad training for anisometropic amblyopia in a series of cases. In the present study, we evaluated the effectiveness of the Occlu-pad for the management of anisometropic amblyopia without the use of occlusion therapy (eyepatch). MATERIALS AND METHODS: We implemented Occlu-pad training for 22 children (mean age +/- standard deviation: 4.7 +/- 1.2 years) with anisometropic amblyopia. The visual acuity before treatment initiation was 0.25 +/- 0.08. The difference in refraction between the healthy and amblyopic eyes was 3.10 +/- 0.58 D. RESULTS: The visual acuity at 3 months and 6 months after training initiation was 0.06 +/- 0.09 and -0.04 +/- 0.07, respectively; this indicates a significant improvement in vision. The compliance rates for Occlu-pad use during 0 - 3 months and 4 - 6 months after training initiation were 88.6% +/- 18.9% and 73.2% +/- 18.9%; these rates decreased significantly with time. CONCLUSIONS: Our findings suggest that the Occlu-pad is an effective tool for the management of anisometropic amblyopia in children. PMID- 29452000 TI - Optimal Items for Assessing Sluggish Cognitive Tempo in Children Across Mother, Father, and Teacher Ratings. AB - A recent meta-analysis identified optimal items for assessing sluggish cognitive tempo (SCT) as distinct from attention deficit/hyperactivity disorder inattention (ADHD-IN), and a preliminary study with teacher ratings of children in the United States found strong support for the convergent and discriminant validity of 15 SCT items. The current study evaluated whether the same 15 SCT items demonstrated convergent and discriminant validity from ADHD-IN in a large, community-based sample of children in Spain, and whether validity results were replicated across mother, father, and teacher ratings. Mothers, fathers, and teachers completed measures of SCT, ADHD-IN, ADHD-hyperactivity/impulsivity, oppositional defiant disorder, limited prosocial emotions, anxiety, depression, shyness, peer rejection, social impairment, and academic impairment on 2,142 Spanish children (49.49% girls; ages 8-13). The 15 SCT symptoms demonstrated convergent validity along with discriminant validity with ADHD-IN across all three informants. The SCT symptom ratings also showed measurement invariance across the informants. In addition, SCT and ADHD-IN factors had different and unique associations with the other symptom and impairment factors. The 15 SCT symptoms identified in this study-consistent across mother, father, and teacher ratings-appear appropriate to serve as a standard symptom set for assessing SCT in children. Use of a common set of symptoms in future studies will advance our understanding of the SCT construct, including its etiology and developmental progression, associations with ADHD and other psychopathologies, links to impairment, and implications for clinical intervention. PMID- 29452001 TI - Sexual Behavior With Noncommercial Partners: A Concurrent Partnership Study Among Middle-Aged Female Sex Workers in China. AB - Female sex workers (FSWs) often engage in concurrent partnerships, meaning they have multiple sexual relationships at the same time. The objective of this study was to investigate sexual concurrency and its associations with condom use and syphilitic infections among FSWs over age 35. Respondent-driven sampling was used to recruit 1,245 FSWs in Nanning, Hefei, and Qingdao, China. FSWs were asked to report whether they had concurrent partners in the past six months. Concurrency was defined as engagement in sex with commercial clients and (1) husbands and boyfriends (n = 167); (2) husbands only (n = 301); or (3) boyfriends only (n = 469). FSWs with only commercial clients were used as the comparison group (n = 308). Across all groups, the percentage of FSWs with prevalent and active syphilis ranged from 19.6% to 25.6% and 9.1% to 11.5%, respectively. Condom use was low with noncommercial sexual partners and was more likely to be used when FSWs' boyfriends had other partners. Three components of the theory of planned behavior were significantly associated with consistent condom use. Concurrent relationships may lead to increased transmission of syphilis at the workplace and family levels. Effective interventions should target concurrency with both commercial and noncommercial partners. PMID- 29452002 TI - Conditions-Based Learning Theory as a Framework for Comparative-Effectiveness Reviews: A Worked Example. AB - : Phenomenon: An evidence-informed era of medical education encourages the generation and use of comparative-effectiveness reviews, yet the reviews often conclude, curiously, that all instructional approaches are equally effective. APPROACH: We used a conditions-based learning theory to structure a review of the comparative-effectiveness literature on electrocardiogram instruction. We searched MEDLINE, EMBASE (Ovid), ERIC (Ovid), PsycINFO (Ovid), and CINAHL (EBSCO) from inception to June 2016. We selected prospective studies that examined the effect of instructional interventions on participants' knowledge and skill with electrocardiogram interpretation. Two reviewers extracted information on the quality of the studies, the effect of instruction on the acquisition of knowledge and skill, and instructional quality. Instructional quality is an index of the extent to which instruction incorporates 4 practices of Gagne's conditions-based learning theory: presenting information, eliciting performance, providing feedback, and assessing learning. FINDINGS: Twenty-five studies (3,286 participants) evaluating 47 instructional interventions were synthesized. The methodological quality of most studies was moderate. Instructional quality varied: All interventions presented information and assessed learning, but fewer than half elicited performances or provided feedback. Instructional interventions that incorporated all 4 components improved trainees' abilities considerably more than those that incorporated 3 or fewer; respectively, standardized mean difference (SMD) = 2.80, 95% confidence interval (CI) [2.05, 3.55], versus SMD = 1.44, 95% CI [1.18, 1.69]. Studies that compared "innovative" to "traditional" types of instruction did not yield a significant pooled effect: SMD = 0.18, 95% CI [-0.09, 0.45]. Insights: The use of a conditions-based learning theory to organize the comparative-effectiveness literature reveals differences in the instructional impact of different instructional approaches. It overturns the unlikely, but common, conclusion that all approaches are equally effective. PMID- 29452003 TI - Acute pneumopericardium: when echocardiography is not enough. PMID- 29452004 TI - Review of Literature on Measurements of Non-invasive Break Up Times, Lipid Morphology and Tear Meniscal Height Using Commercially Available Hand-held Instruments. AB - : Purpose/aims: Dry eye is a common multi-factorial disease characterized by tearfilm dysfunction. Diagnosis of dry eye requires documentation of tear status with non-invasive tear break up times (NIBUT), tear meniscal height (TMH), and tearfilm lipid layer. These parameters objectively assess tear stability and indirectly, the functional impact of meibomian gland dysfunction. While it is obvious that portable instrumentation gives broader access than fixed instrumentation, its value would be limited if it is unreliable and its precision and accuracy substantially worse than fixed instruments. MATERIALS/METHODS: Because of the lack of systematic reviews concerning the Tearscope, we performed a scoping review of the literature to determine 1. the ranges of the tear parameters as measured by the device, 2. relationship between these measurements and other clinical variables, 3. Information about intra or inter-observer agreement, and comparison with another technique, where available. RESULTS: We found 22 reports related to NIBUT, 18 reports concerning tearfilm lipid morphology (LM) based on classification of interference patterns, and 8 reports on TMH. While publication of these reports indicates an acceptance of the reliability of portable instruments, we interrogated these studies further to evaluate the results obtained from portable devices and found that there was no equivalent measurements in fixed devices (LM) or measurements differ considerably from fixed devices (NIBUT). In the case of TMH, portable measurements were similar to those by traditional slit-lamp microscopy. There were relatively few studies on TMH measured using handheld devices, but it was found to be correlated to NIBUT but not the Schirmer test values. CONCLUSIONS: Imaging algorithms in portable tearfilm instruments should be further standardized to facilitate wider adoption and evaluation. In the next few years, new emerging technologies will employ a strategy of non-invasive tear testing that is portable and relatively inexpensive, and these will enhance adoption of such tools in the clinic.

Substance use references occur more frequently in rap/hip-hop than in other music genres. OBJECTIVES: The aim was to examine whether the exposure to rap/hip-hop lyrics referring to substance use affected cigarette smoking. METHODS: An experiment with a 3-group between subject design was conducted among 74 daily smoking young adults ranging in age from 17 to 25 years old. Three conditions were tested in a mobile lab (camper vehicle) from May to December 2011, i.e., regular chart pop music (N = 28), rap/hip-hop with non-frequent references to substance use (N = 24), and rap/hip-hop with frequent references to substance use (N = 22). RESULTS: One-way ANOVA showed that participants listening to substance use infused rap/hip-hop songs felt significantly less pleasant, liked the songs less, and comprehended the songs less compared to participants listening to pop songs. Poisson loglinear analyses revealed that compared to the pop music condition, none of the two rap/hip-hop music conditions had a significant effect on acute smoking. Thus, contrary to expectations, the two different rap/hip-hop conditions did not have a significantly different effect on acute smoking. CONCLUSIONS: Listening to rap/hip-hop, even rap hip/hop with frequent referrals to substance use (primarily alcohol and drug use, and general smoking referrals), does not seem to encourage cigarette smoking among Dutch daily-smoking young adults, at least short term.

AB - Androgenetic alopecia, also known as male and female pattern hair loss, is a very prevalent condition; however, approved therapeutic options are limited. Fractionated laser has been proposed to assist in penetration of topical medications to the cutaneous tissue. We present four cases of androgenetic alopecia that underwent treatment with a non-ablative erbium glass fractional laser followed by the application of topical finasteride 0,05% and growth factors including basic fibroblast growth factor, insulin-like growth factor, vascular endothelial growth factor, and copper peptide 1%. During all laser treatment sessions, eight passes were performed, at 7 mJ, 3-9% of coverage and density of 120 mzt/cm2. A positive response was observed in all of the four patients. Photographs taken 2 weeks after the last session showed improvement in hair regrowth and density. No significant side effects were observed.

AB - OBJECTIVE: Patient expectations are related to treatment outcome across a broad variety of patient conditions. Here we sought to examine factors associated with the expectation of complete relief from treatment for spinal pain. DESIGN: Secondary analysis of data pooled from two randomized controlled trials of conservative rehabilitation interventions. PATIENTS: 252 patients (103 men, 149 women) with neck (n = 140) or back (n = 112) pain. METHODS: We used logistic regression model with backward elimination to test which patient clinical or demographic factors were most related to the expectation of complete relief. MAIN OUTCOME MEASURES: The expectation of complete recovery, which was collected at the baseline examination visit in the primary trials. RESULTS: The final model examining the contributions of patient and clinical characteristics to the expectation of complete relief included two significant interactions. First, increasing disability was associated with increased odds of expecting complete recovery in women while there was very little change for men across levels of disability (OR 0.9 [95%CI 0.8, 0.9]). Second, patients with low fear and a sudden onset of pain had higher odds of expecting recovery than patients with a gradual onset of pain (OR 0.7 [95%CI 0.5, 0.97]). A main effect for education level of the patient was also significant with better odds for expecting complete recovery for college educated patients compared to those with graduate school education (OR 5.0 [95%CI 1.9, 13.4]). CONCLUSION: The results should assist physical therapists to recognize patients who may have lower expectations of recovery and plan pre-treatment education interventions. PMID- 29452025 TI - Subgrouping the users of a specialized app for eating disorders. AB - Although mobile technologies for eating disorders (EDs) are burgeoning, there is limited data about the clinical characteristics of individuals using specialized smartphone applications (apps) without accompanying traditional forms of treatment. This study evaluated whether the users of an ED app cluster in clinically meaningful groups. Participants were 1,280 app users (91.3% female; mean age 27) who reported not being in a weekly treatment for their ED. A hierarchical cluster analysis distinguished five groups of participants, all approximating DSM-5 ED categories. One cluster comprised of non-female, ethnically diverse users with Bulimia Nervosa features. Findings suggest that app users resemble known patient classifications.

AB - OBJECTIVE: We described the general movements (GMs) in the fidgety period and the motor performance of two infants who were exposed to Zika virus (ZIKV) during distinct trimesters of gestation. METHODS: Infants were assessed at 4 and 12 months of age. Prechtl's GM assessment and the Alberta Infant Motor Scale were used. RESULTS: In Case 1, the mother presented confirmed ZIKV infection in the 10th week of gestation and the infant was born full-term with brain abnormalities and microcephaly. Fidgety movements were absent at 16 weeks after term and motor development was severely impaired at 12 months of age. In Case 2, the mother presented confirmed ZIKV infection in the 34th week of gestation and the infant was born full-term with no signs of brain changes or microcephaly. Fidgety movements at 13 weeks were normal in presentation and motor outcome was typical at 12 months. CONCLUSION: GM assessment can be useful for ZIKV-exposed infants. These findings represent the first information on GMs and long-term motor outcomes in ZIKV-exposed infants. PMID- 29452027 TI - Short interval overnight laser scanning suggests sub-circadian periodicity of tree turgor. AB - A recent study by Zlinszky et al., 1 uses high-resolution terrestrial laser scanning to investigate the variability of overnight movement of leaves and branches in vascular plants. This study finds among others that the investigated plants show periodic movements of around one centimetre in amplitude and 2-6 hour periodicity. Sub-circadian process dynamics of plants were so far not in focus of research, but here we compare the findings with other published cases of short term periodicity in leaf turgor, sap flow and especially trunk diameter. Several authors have noted overnight variations in these parameters within periods of several hours and in absence of environmental changes with similar dynamics. We revisit the unknown questions of short-term plant movement and make a suggestion for future research. PMID- 29452029 TI - Intense pulsed light is effective in treating postburn hyperpigmentation and telangiectasia in Chinese patients. AB - Intense pulsed light (IPL) has been used to treat postinflammatory hyperpigmentation and telangiectasia in Fitzpatrick type I -II skin. However, its therapeutic effects after superficial second-degree burns in Asian populations with Fitzpatrick type III-IV skin are uncertain. Thirty-five Han Chinese patients with facial or hand hyperpigmentation and telangiectasia due to second-degree fire burns received treatment with IPL. Each patient underwent 2-6 treatments over 3-5 weeks. The laser wavelength was 560-615 nm. Skin pigmentation was evaluated by two plastic surgeons as well as by the patients themselves (self evaluation) before treatment at the end of the treatment cycle and 1 year after the first treatment. Blood flow in telangiectasia skin was measured by laser Doppler flow. The results showed that IPL significantly lessened hyperpigmentation so that close to normal skin color was achieved after the treatment cycles, and pigmentation did not reoccur 1 year after the first treatment. Approximately 82.9% of the patients were satisfied with their treatment outcomes. There were no post-treatment complications. Doppler showed a significant decreased blood flow in telangiectasia after treatment. In conclusion, IPL is an effective and safe modality for Chinese patients with hyperpigmentation and telangiectasia after fire burns. PMID- 29452028 TI - Meningococcal disease and vaccination: Knowledge and acceptability among adolescents in Italy. AB - This study aimed to evaluate the knowledge, attitudes and practice about invasive meningococcal disease and the relative vaccine for adolescent in Italy. A cross sectional study was conducted from March to May 2017 among a sample of 771 adolescents in the geographic area of Naples (Italy). A self-administered anonymous questionnaire was used to collect demographics, knowledge about meningitis and preventive measures, perceived risk for contracting meningitis, attitude towards the utility of meningococcal vaccine, and adolescents' willingness to receive a meningococcal vaccine. 85.2% of participants have heard about meningitis, 57.2% knew that adolescents are a susceptible population but only 30.3% knew that meningitis is transmitted by respiratory droplets. Moreover, 40.5% of adolescents knew that meningitis is a vaccine-preventable disease and that adolescents could be vaccinated. This knowledge was significantly greater among female participants, among those who talk with parents about vaccinations, among who have received information about vaccinations from physicians, among who have positive attitude towards the utility of information received on vaccinations and among who don't feel the need of additional information about meningitis. As regard the attitudes, 25.7% of adolescents thought that the vaccine was very useful. Males, adolescent aged 11-13 years, those who had the positive attitude towards the utility of information received about vaccinations and those who had received at least one vaccination in the last year were more likely to have this attitude. The our finding identifies the need to improve adolescents' knowledge about meningitis and its related vaccinations, through correct health education, in order to have a good acceptance of vaccination.

PMID- 29452031 TI - Prehospital Cervical Spine Motion: Immobilization Versus Spine Motion Restriction. AB - OBJECTIVE: This study aims to evaluate the efficacy of two different spinal immobilization techniques on cervical spine movement in a simulated prehospital ground transport setting. METHODS: A counterbalanced crossover design was used to evaluate two different spinal immobilization techniques in a standardized environment. Twenty healthy male volunteers (age = 20.9 +/- 2.2 yr) underwent ambulance transport from a simulated scene to a simulated emergency department setting in two separate conditions: utilizing traditional spinal immobilization (TSI) and spinal motion restriction (SMR). During both transport scenarios, participants underwent the same simulated scenario. The main outcome measures were cervical spine motion (cumulative integrated motion and peak range of motion), vital signs (heart rate, blood pressure, oxygen saturation), and self reported pain. Vital signs and pain were collected at six consistent points throughout each scenario. RESULTS: Participants experienced greater transverse plane cumulative integrated motion during TSI compared to SMR (F1,57 = 4.05; P = 0.049), and greater transverse peak range of motion during participant loading/unloading in TSI condition compared to SMR (F1,57 = 17.32; P < 0.001). Pain was reported by 40% of our participants during TSI compared to 25% of participants during SMR (chi2 = 1.29; P = 0.453). CONCLUSIONS: Spinal motion restriction controlled cervical motion at least as well as traditional spinal immobilization in a simulated prehospital ground transport setting. Given these results, along with well-documented potential complications of TSI in the literature, SMR is supported as an alternative to TSI. Future research should involve a true patient population. PMID- 29452030 TI - Comparative phylogenetic and expression analysis of small GTPases families in legume and non-legume plants. AB - BACKGROUND: Small monomeric GTPases act as molecular switches in several processes that involve polar cell growth, participating mainly in vesicle trafficking and cytoskeleton rearrangements. This gene superfamily has largely expanded in plants through evolution as compared with other Kingdoms, leading to the suggestion that members of each subfamily might have acquired new functions associated to plant-specific processes. Legume plants engage in a nitrogen-fixing symbiotic interaction with rhizobia in a process that involves polar growth processes associated with the infection throughout the root hair. To get insight into the evolution of small GTPases associated with this process, we use a comparative genomic approach to establish differences in the Ras GTPase superfamily between legume and non-legume plants. RESULTS: Phylogenetic analyses did not show clear differences in the organization of the different subfamilies of small GTPases between plants that engage or not in nodule symbiosis. Protein alignments revealed a strong conservation at the sequence level of small GTPases previously linked to nodulation by functional genetics. Interestingly, one Rab and three Rop proteins showed conserved amino acid substitutions in legumes, but these changes do not alter the predicted conformational structure of these proteins. Although the steady-state levels of most small GTPases do not change in response to rhizobia, we identified a subset of Rab, Rop and Arf genes whose transcript levels are modulated during the symbiotic interaction, including their spatial distribution along the indeterminate nodule. CONCLUSIONS: This study provides a comprehensive study of the small GTPase superfamily in several plant species. The genetic program associated to root nodule symbiosis includes small GTPases to fulfill specific functions during infection and formation of the symbiosomes. These GTPases seems to have been recruited from members that were already present in common ancestors with plants as distant as monocots since we failed to detect asymmetric evolution in any of the subfamily trees. Expression analyses identified a number of legume members that can have undergone neo- or sub-functionalization associated to the spatio-temporal transcriptional control during the onset of the symbiotic interaction.

AB - OBJECTIVE: To examine the association between degree of real-life closeness of social media (SM) contacts and depressive symptoms. PARTICIPANTS: Students ages 18-30 (N = 1124) were recruited in August 2016. METHODS: Participants completed an online survey assessing SM use and depression. We used multivariable logistic regression to assess associations between real-life closeness of SM contacts and depressive symptoms. RESULTS: After controlling for covariates, each 10% increase in the proportion of SM friends with whom participants had no face-to-face relationship was associated with a 9% increase in odds of depressive symptoms (AOR = 1.09; 95% CI = 1.05-1.13). However, each 10% increase in the proportion of SM friends with whom participants had a close face-to-face relationship was associated with a 7% decrease in depressive symptoms (AOR = 0.93; 95% CI = 0.89 0.97). CONCLUSIONS: Having no in-person relationship with SM contacts is associated with increased depressive symptoms; however, having close in-person relationships with SM contacts is associated with decreased depressive symptoms.

AB - Health care policies for the elderly are complex, multidimensional, and contextually circumscribed. While engagement of health experts, economists, health care administrators, and political leaders is generally viewed as instrumental to the success and sustainability of eldercare programs, the elders themselves are often viewed as passive recipients of care and not included in the policy processes. Experiences and expectations from users' perspectives can be invaluable information for policy formulation and systems design. This paper examines a participatory policy process using a "citizens' jury" to promote public engagement in eldercare policy. The process was initiated by the National Health Commission Office in Thailand to explore how a citizens' jury as a model for civic deliberation can be utilized to provide sophisticated policy recommendations on long-term care policies for the elderly. The objectives of this paper are to (1) examine how public participation in health policy can be actualized through the citizens' jury as an operational model, (2) understand the strengths and weaknesses of the ways the idea was implemented, and (3) provide recommendations for further use of the model. Details of how a citizens' jury was deployed are discussed, with recommendations for further use provided at the end. PMID- 29452044 TI - Food Addiction is Associated with Higher Neuroticism, Lower Conscientiousness, Higher Impulsivity, but Lower Extraversion in Obese Patient Candidates for Bariatric Surgery. AB - BACKGROUND: The "food addiction" phenotype identifies a subpopulation of individuals experiencing substance-dependence symptoms toward specific foods. In the current debate on whether the "food addiction" phenotype should be considered as an addictive disorder, assessment of the personality traits associated with this phenotype would provide arguments for or against the "food addiction" phenotype and its inclusion in the "substance-related and addictive disorder" category. OBJECTIVES: To assess the personality characteristics associated with the "food addiction" phenotype in obesity surgery candidates (i.e., big five personality dimensions, alexithymia and impulsivity). METHODS: We assessed food addiction (Yale Food Addiction Scale), personality dimensions (Big Fig Inventory), impulsivity (Barratt Impulsiveness Scale-11th version) and alexithymia (Toronto Alexithymia Scale-20 items) in 188 bariatric surgery candidates recruited between July 2013 and November 2015 in the Nutrition Department of the University Hospital of Tours. We used chi-squared tests and Student's tests or Mann-Whitney-U-tests to determine the factors associated with food addiction. RESULTS: Prevalence of current food addiction was 16.5%. Patients with (vs. without) food addiction had lower conscientiousness (p = .047), higher neuroticism and lower extraversion (ps < 0.001), but there was no difference in terms of agreeableness (p = 0.42) or openness (p = 0.16). They were more frequently single (p = .021) and reported higher alexithymia (ps < .001) and higher impulsivity sub-scores (ps<.05). Conclusions/Importance: Food addiction shares personality traits with substance-related disorders (regarding neuroticism, conscientiousness, impulsivity, alexithymia), and one distinctive trait (low extraversion). This study provides additional data that enrich the discussion on whether the "food addiction" phenotype should be included or not in the "substance-related and addictive disorder" category.

AB - In spite of a complete lack of Research and Development (R&D) preparedness, the 2013-2016 West-Africa Ebola experience demonstrated that it is possible to compress R&D timelines to less than a single year, from a more usual decade or longer. This is mostly to be credited to an unprecedented collaborative effort building on the availability of a small number of candidate diagnostic tests, drugs and vaccines that could be moved rapidly into the clinical phase evaluation. The World Health Organization (WHO) led international consultations and activities - including the organization of a successful Ebola vaccine efficacy trial in Guinea - as a contribution to the unprecedented global efforts to control the Ebola epidemic. Since 2015, WHO expert teams and partners are implementing a novel R&D model for emerging infectious pathogens which are the most likely to cause severe outbreaks in the future, and for which no or only few medical countermeasures are available: the WHO R&D Blueprint. The objective for the Blueprint is the fostering of a R&D environment which is prepared for quickly and effectively responding to outbreaks due to emerging infectious disease.

AB - BACKGROUND: Clarithromycin and metronidazole resistance of Helicobacter pylori is increasing worldwide and has resulted in a loss in the effectiveness of therapeutic regimens. We aimed to evaluate common mutations of resistance genes to clarithromycin (A2143G, A2142G and A2142C) and metronidazole (rdxA and frxA) in H. pylori strains in formalin-fixed, paraffin-embedded gastric biopsies. METHODS: A total of 110 tissue blocks from children suspected of H. pylori infection were included. After DNA extraction, UreC PCR was performed. Specific primers and restriction enzymes by PCR-RFLP were used for analysis of A2143G and A2142G mutations. To detect A2142C and assess frequent mutations of metronidazole resistance, specific primers and PCR method were used. RESULTS: One hundred cases of H. pylori (91%) were by PCR. Of 34 (34%) clarithromycin-resistant isolates 17 (50%), 10 (29%) and 7 (21%) had A2143G, A2142G, A2142C, respectively. Resistance rate to metronidazole was 60% (N = 60). In sequencing rdxA and frxA in the mutated strains, missense mutations were most frequent (60 and 57%, respectively), and there were differences in frameshift and non-sense mutations (p < 0.001). CONCLUSION: Resistance rate to clarithromycin was high and the highest percentage of mutation was of A2143G. PCR-RFLP was used directly with formalin-fixed gastric biopsies, thus, avoiding the requirement for time consuming culture-based methods. The isolates that developed resistance were mainly associated with mutations of both rdxA and frxA genes.

AB - A difference in degree of acculturation between immigrant parents and children, known as intergenerational cultural dissonance (ICD), is a risk factor for adolescent alcohol use. We used path analysis with 292 Vietnamese and Cambodian adolescents from immigrant families in the United States to measure potential mediators (family conflict, parental involvement/monitoring, association with deviant peers) of the ICD-alcohol use relationship. The hypothesized model was an adequate data fit among both groups. Among Cambodian adolescents, higher ICD levels significantly predicted increased family conflict, which in turn was associated with reduced parental involvement/monitoring, increased association with deviant peers, and a subsequently higher risk of alcohol use (p < .05 for all coefficients). We also found significant indirect effects of ICD on alcohol use among Vietnamese adolescents through family conflict and parental involvement/monitoring (p < .05 for all coefficients) but not through peer behavior. For both groups, there was no direct effect of ICD on alcohol use outside these pathways. Identification of significant mediators provides potential targets for preventing alcohol use among these populations. In addition, differences in path coefficients between Vietnamese and Cambodian adolescents underscore the importance of conducting analyses stratified by Asian ethnic group. PMID- 29452051 TI - Using the Ecological Model to understand influences on college student vaping. AB - : Objective The Ecological Model was used to examine the social and environmental influences of the college environment on e-cigarette use (vaping) among college students. PARTICIPANTS: Undergraduate college student e-cigarette users (vapers) across three large college campuses in the southwest US from Jan 2015- Aug 2016. METHODS: Thirty-three interviews were conducted. Transcribed interviews were coded then analyzed for themes. RESULTS: College student vapers report multiple levels of influence on their vaping beyond personal beliefs and peer influences, including parents, explicit campus and community messaging, community member requests, and respect for others. College student vapers also describe constant associations with smokers in allowable public places to vape. CONCLUSIONS: Parents, community members, campus policy, and the physical environment all influence where and when college students vape. Health communication messages to prevent college student vaping should incorporate alternative messages that are important to college students, such as respect for others and social image. PMID- 29452052 TI - Agency and fatalism in older Appalachian women's information seeking about gynecological cancer. AB - Researchers consider older women in rural Appalachia to have low levels of agency and high levels of fatalism regarding decision making about cancer treatment. Using the life course perspective, we examined older women's agency with information seeking about gynecological cancer. Semistructured interviews with 20 White women living in central Appalachia revealed four trajectories: Surrendering Control, Accepting Death, Self-Care, and Advocacy, each with its own forms of agency. Some women experienced personal transformation, increased self-efficacy, and a passion for community empowerment. Fatalism was not understood apart from placing trust in medical expertise. We implore researchers to further explore rural expressions of agency. PMID- 29452053 TI - Social adjustment and repressive adaptive style in survivors of pediatric cancer. AB - PURPOSE: The aim of the study was to explore the relationship between repressive adaptive style and self-reports of social adjustment in survivors of pediatric cancer compared to their siblings. We hypothesized that there would be a greater proportion of repressors among survivors of pediatric cancer compared to siblings, and that repressive adaptive style would be significantly associated with more positive self-reports of social adjustment. METHODS: We utilized a cross-sectional approach. Seventy-seven families participated. Survivors of pediatric cancer (n = 77, 48% male; 8-18 years of age) and one sibling (n = 50, 48% male; 8-18 years of age) completed measures assessing repressive adaptive style and social adjustment. As well, one parent from each family completed a socio-demographic questionnaire. Questionnaire packages were mailed to eligible families who agreed to participate, and were mailed back to investigators in a pre-addressed, pre-stamped envelope. RESULTS: Chi-square analyses revealed there was no significant difference in the proportion of repressors among survivors and siblings. Social adjustment scores were subjected to a two (group: survivor, sibling) by two (repressor, nonrepressor) ANCOVA with gender and age as covariates. There was a significant main effect of repressive adaptive style (F = 5.69, p < .05, eta2 = 0.05) with a modest effect. Survivors and siblings with a repressive style reported significantly higher social adjustment scores (M = 106.91, SD = 11.69) compared to nonrepressors (M = 99.57, SD = 13.45). CONCLUSIONS: Repressive adaptive style explains some of the variance in survivors and siblings' self-reports of social adjustment. Future research should aim to better understand the role of the repressive adaptive style in survivors and siblings of children with cancer. PMID- 29452054 TI - Community resources support adherence to treatment for childhood cancer in El Salvador. AB - OBJECTIVE: In order to reduce nonadherence and treatment abandonment of children with cancer in El Salvador, institutions located nearby the patients' homes were involved to provide support. Methodological approach: Health clinics and municipality offices in the patients' communities were asked to assist families who were not promptly located after missing hospital appointments, or those whose financial limitations were likely to impede continuation of treatment. Data was collected about the number of contacted institutions, the nature of help provided, staff's time investments, and parents' perceptions about the intervention. FINDINGS: Local institutions (133 from 206 contacts) conducted home visits (83), and/or provided parents with money (55) or transportation (60). Parents found this support essential for continuing the treatment but they also encountered challenges regarding local institutions' inconsistencies. Nonadherence and abandonment decreased. IMPLICATIONS: Economic burden was reduced on both the families and the hospital. Involvement of external institutions might become regular practice to support families of children with cancer. PMID- 29452055 TI - Feeling an Invisible Wall: The Experience of Iranian Women's Marital Relationship After Surgical Menopause: A Qualitative Content Analysis Study. AB - Sexual relationships after surgical menopause matter when talking about sex is taboo and marriage is the only justified way to meet sexual needs. In this qualitative research study, 22 surgical menopausal women shared their experiences of sexual/marital relationship after surgery through in-depth, face-to-face, semi structured interviews. Qualitative content analysis technique was used for data analysis. An overarching theme entitled "feeling an invisible wall" reflected this experience. It comprised three categories: (1) declined marital intimacy, (2) disarming, and (3) transformation of societal norms into concerns. This study proposed new contextual information about the marital relationship of Iranian women after surgical menopause that was not openly articulated before and which may be applicable for others in such contexts. Women's main concern was the emotional separation because of the sexual consequences of the surgery. Healthcare providers should be aware of women's concerns, which may alter their marital relationship. They must provide individualized care, education, and support for couples to make thoughtful decisions about rebuilding their sexual relationship. Results may also have implications for psychiatrists, sex/marital therapists, and probably clergy who have the authority to openly address this important issue to the public. PMID- 29452056 TI - Promoting addiction medicine teaching through functional mentoring by co-training generalist chief residents with faculty mentors. AB - BACKGROUND: Generalist physicians should play a vital role in identifying and managing individuals with substance use but are inadequately trained to do so. METHODS: This 5-year (2008-2012) controlled educational study assessed whether internal medicine and family medicine chief residents' (CRs) addiction medicine teaching increased by co-training with faculty mentors at a Chief Resident Immersion Training (CRIT) program in addiction medicine. All CRIT CR attendees identified a residency program faculty mentor to support addiction medicine teaching after CRIT through functional mentoring with a focus on developing and implementing an Addiction Medicine Teaching Project ("Teaching Project"). Approximately half of the CRs attended CRIT with their mentor (co-trained) and half without their mentor (solo-trained). Addiction medicine teaching outcomes were compared between groups using 6- and 11-month questionnaires and 4 bimonthly teaching logs. Of co-trained CRs, mentor characteristics that positively influenced addiction medicine teaching outcomes were identified. RESULTS: One hundred CRs from 74 residency programs attended CRIT from 2008 to 2012; 47 co trained with their mentors and 53 solo-trained without their mentors. At 6-month follow-up, the co-trained CRs were more likely to meet at least monthly with their mentor (22.7% vs. 9.6%, P < .01) and more likely to identify their mentor as a facilitator for Teaching Project implementation (82.2% vs. 38.5%, P < .01). At 11-month follow-up, a higher percentage of co-trained CRs had completed their Teaching Project (34.0% vs. 15.1%, P < .05). Both CR groups had similarly large increases in other addiction medicine teaching outcomes. Mentors with more experience, including years of teaching, was associated with better CR Teaching Project outcomes. CONCLUSIONS: Co-training generalist chief residents with a faculty mentor appeared to facilitate functional mentoring-driven Teaching Project implementation but did not further increase already high levels of other addiction medicine teaching. Faculty mentors with more years of teaching experience were more effective in facilitating Teaching Project implementation. PMID- 29452057 TI - Use of Twitter to Assess Viewer Reactions to the Medical Drama, Code Black. AB - Fictional medical television programs are popular with viewers and have been shown to influence health-related outcomes. We sought to systematically analyze real-time viewer discourse on Twitter related to the new medical drama, Code Black. We retrieved all Twitter posts (tweets) and metadata around the time of the airing of Code Black for four consecutive weeks. We developed a codebook using both content assessment of Twitter messages (tweets) and theory-based variables used in entertainment education analyses. We coded all tweets that occurred during the Eastern Standard Time (EST) airing of the program. Tweets that fell into at least one coding category were further analyzed by two independent researchers. We collected a total of 19,369 tweets, with 54% of total tweets originating during the EST airing of the program. There were 1,888 tweets that fit into one or more of six broad coding categories. Qualitative analysis revealed several key themes including real-life motivation to pursue health sciences careers based on the program, engagement regarding medical accuracy, and respect for the nursing profession. Examination of tweets related to Code Black provides insight into viewer discourse and suggests that Twitter may provide a vehicle for leveraging program engagement into real-life discussion and inquiry. PMID- 29452058 TI - A meta-analysis of effectiveness of E-interventions to reduce alcohol consumption in college and university students. AB - OBJECTIVE: To evaluate the effectiveness and moderators of E-Interventions versus assessment only (AO) controls in the reduction of alcoholic drinks per week (DPW) in university students. STUDY DESIGN AND METHODS: Cochrane library, CINAEL, ERIC, MEDLINE, PsycINFO, PubMed, and Web of Science were searched up to June 2017. Studies were included if they were: an RCT, assessed the effectiveness of E Interventions at reducing DPW, and employed university/college students. 23 studies (N = 7,614) were included and quality was assessed using the JADAD scale. RESULTS: Weighted mean effect sizes were calculated using random-effects models. These showed a small, significant effect of E-Interventions at reducing the number of alcoholic DPW. Moderator analysis found a significant advantage for web based personalised feedback interventions compared to other E-Interventions. CONCLUSIONS: E-Interventions show a small, significant effect at reducing mean alcoholic DPW. Personalised feedback E-Interventions showed the strongest effect. PMID- 29452059 TI - New Zealand adolescents' concerns about their alcohol use and access to services: Associations with ethnicity and other factors. AB - Using a national survey of 8,500 New Zealand high school students, we investigated adolescents' concerns about their drinking, associated factors including help-seeking preferences and access to health care services, and how these varied by ethnicity and level of socioeconomic deprivation. Approximately 23.9% of the 3,704 current drinkers reported concerns (i.e., being worried about their drinking and/or having tried to cut down). Regression analyses revealed that Maori and Pacific youth were more likely than their New Zealand European peers to be concerned about their drinking. Concerned drinkers were more likely than nonconcerned drinkers to report hazardous drinking behaviors and alcohol related problems, but these associations varied by age, ethnicity, and socioeconomic deprivation. Help-seeking preferences differed strongly by ethnicity. Concerned drinkers, and Maori and Pacific drinkers, were more likely to report difficulties accessing health care and alcohol and drug services. The factors associated with adolescents' drinking concerns and paradoxical difficulties accessing health care highlight the importance of engaging adolescents in developing responsive and equitable services. PMID- 29452060 TI - U.S. adolescent alcohol use by race/ethnicity: Consumption and perceived need to reduce/stop use. AB - Understanding racial/ethnic drinking patterns and service provision preferences is critical for deciding how best to use limited alcohol prevention, intervention, and treatment resources. We used nationally representative data from 150,727 U.S. high school seniors from 2005 to 2016 to examine differences in a range of alcohol use behaviors and the felt need to reduce or stop alcohol use based on detailed racial/ethnic categories, both before and after controlling for key risk/protective factors. Native students reported particularly high use but corresponding high felt need to reduce/stop use. White and dual-endorsement students reported high use but low felt need to stop/reduce alcohol use. PMID- 29452061 TI - What's so appealing? An examination of emotional appeals and viewer engagement in safe-sex PSAs and condom advertisements. AB - Whereas advertisements strive to increase revenue, PSAs work to educate and inform. Even though both share the similar goal of persuasion, advertising tends to lead to more effective sales, unlike PSAs, which can have little effect on audience behaviors. Using a systematic, quantitative content analysis, this study examines emotional appeals and viewer engagement in safe-sex PSAs and condom advertisements in online videos (N = 132). PSAs with humor appeals received more viewer attention in terms of views, comments, and ratings than humorous advertisements. Recommendations for designing public health campaigns are discussed in terms of specific appeals for garnering audience attention. PMID- 29452062 TI - The Buddy Benefit: Increasing the Effectiveness of an Employee-Targeted Weight Loss Program. AB - It is well known that significant others (particularly romantic partners) can influence people's weight management efforts. However, what constitutes effective support-and from which type of individual (e.g., romantic partner, family member, friend)-is unclear. Thus, framed by confirmation theory, we assessed the effectiveness and types of communication of a weight-loss "buddy" through reports of 704 individuals enrolled in a 15-week synchronous online weight-loss program. Roughly 54% of participants chose buddies; and those who did lost more weight and waist inches than those who were involved in the program without buddy support. We also found that a combination of high accepting and high challenging messages from buddies was associated with the greatest decrease in body mass index (BMI) as well as the greatest reduction in waist size. Furthermore, the support by romantic partners paralleled support by other types of buddies. Having a supportive buddy who was not a romantic partner was just as effective as turning to a romantic partner for assistance. This study underscores the important role of a buddy in supporting weight-loss program involvement and encourages individuals to consider enlisting the help of a buddy, as opposed to losing weight alone, in order to maximize weight management effectiveness. PMID- 29452063 TI - Getting Started: An Empirically Derived Logic Model for Age-Friendly Community Initiatives in the Early Planning Phase. AB - Age-friendly community initiatives (AFCIs) foster efforts across stakeholders to make localities more supportive and inclusive of older adults, and potentially better for residents of all ages. This study drew on in-depth interviews with leaders of nine newly forming AFCIs in northern New Jersey to develop an empirically based logic model for the initiatives in the early planning phase. The results obtained from a conventional content analysis indicated three main activities in the early planning phase: assessing the community; meeting; and communicating with stakeholders; and facilitating communitywide communications. These activities worked toward two outputs: increased understanding of aging in the community and more engaged stakeholders in aging. Participants described leveraging the contributions of lead staff, consultants, elected officials, organizational partners, volunteers, interns, funders, and other AFCIs to engage in their focal activities. Based on these findings, a logic model for AFCIs in the early planning phase is presented. AFCI leaders can draw on this model to evaluate AFCI processes and outcomes in their formative stages, as well as to strategically plan for the start of an AFCI within a given locality. Findings also suggest important directions for future research on the development of AFCIs and the community changes that they seek to influence. PMID- 29452064 TI - College students with congenital heart disease: A critical time for transition. AB - : As medical and surgical advances improve, more young adults with congenital heart disease (CHD) are attending college. This case study illustrates some of the issues that these young adults may face as they attend college and discusses the role that college health practitioners can play in easing that transition. PARTICIPANTS: A case of a male with CHD presenting to the college health clinic with a new onset headache. METHODS: The authors discuss some of the unique challenges that college health practitioners may face when caring for students with CHD. In addition, they make recommendations on how best to care for these patients and how best to coordinate care with CHD students other care providers. RESULTS: This student with a history of coarctation of the aorta presented with new onset headaches and was found to have high blood pressure. He was diagnosed with recurrent coarctation, underwent percutaneous treatment with stenting and quickly resumed classes. CONCLUSIONS: As more students with CHD enter college, college health providers will need to understand some of the health risks that CHD students face. In addition, understanding some of the optimal ways to coordinate care with CHD providers can ease the transition that CHD students face as they enter college. PMID- 29452065 TI - Past-year nonmedical use of prescription drugs among women on probation and parole: A cross-sectional study. AB - BACKGROUND: Prescription drug-related overdose deaths have increased dramatically in recent years. Women in the justice system experience high rates of drug use, victimization, trauma symptoms, and other health problems and would appear to be at high risk for nonmedical use of prescription drugs (NMUPD). This study will be among the first to describe prevalence and correlates of NMUPD among this population. METHODS: This cross-sectional study collected data from 406 victimized women on probation and parole between 2010 and 2012. In a multiple logistic regression model, we differentiated women who reported past-year NMUPD from those who did not using demographic, health, other drug use, substance use treatment, and trauma symptom severity variables. RESULTS: Past-year NMUPD was reported by 26.8% (n = 109) of the overall sample. Women reporting NMUPD were significantly younger and more likely to be white. Past-year use of alcohol (adjusted odds ratio [AOR]: 3.3; 95% confidence interval [CI]: 1.8-6.1), marijuana (AOR: 3.6; 95% CI: 1.8-7.0), methamphetamines (AOR: 6.1; 95% CI: 1.7 21.3), and heroin (AOR: 8.4; 95% CI: 2.0-35.2) were significantly associated with NMUPD. Additionally, each unit increase in the measure assessing bodily pain was associated with a 40% increase (AOR: 1.4; 95% CI: 1.1-1.7) in the odds of NMUPD. Finally, meeting diagnostic criteria for posttraumatic stress disorder almost doubled (AOR: 1.9; 95% CI: 1.1-3.4) the odds of reporting past-year NMUPD. CONCLUSIONS: Victimized women on probation and parole report high rates of NMUPD, and this behavior intersects with other complex social, behavioral, psychological, and physical needs. The authors recommend increased access to trauma-informed correctional care among women in the justice system.

PMID- 29452067 TI - Alcohol and drug use among deaf and hard-of-hearing individuals: A secondary analysis of NHANES 2013-2014. AB - BACKGROUND: Within the field of behavioral health research, one of the most understudied populations is the US deaf and hard-of-hearing (D/HH) population-a diverse group of individuals with hearing loss that have varied language and communication preferences, community affiliations, and sociocultural norms. Recent research identified concerning behavioral health disparities experienced by the D/HH population; yet, little research has been conducted to extend these findings to the topic of substance use disorder. METHODS: To begin to fill this gap, the authors conducted a secondary analysis of data from the 2013-2014 administration of the National Health and Nutrition Examination Survey, comparing alcohol and drug use between participants based on their reported hearing status, i.e., D/HH or hearing. RESULTS: Findings suggest that the overall lifetime prevalence of alcohol and drug use does not differ based on hearing status, and that D/HH and hearing adolescents begin using cannabis on a similar timeline. However, findings also revealed that D/HH respondents were more likely to have been regular cannabis users and heavy alcohol users than hearing respondents. In other words, when D/HH individuals use substances, they tend to be heavy users. CONCLUSIONS: These findings stress the importance of directing resources to the prevention and treatment of heavy alcohol use in the D/HH population, given that binge drinking is associated with a number of health problems and social consequences. Additionally, the continuation of this empirical work is rather urgent given recent legislative changes regarding cannabis use. D/HH individuals possess a number of risk factors for substance use disorder and, as such, may be more greatly impacted by these legislative changes than individuals from the general US population. It is imperative that this impact be captured by future research efforts in order to inform the development of prevention and intervention efforts for the traditionally underserved D/HH population. PMID- 29452068 TI - Glycyrrhizin attenuates histamine-mediated MUC5AC upregulation, inflammatory cytokine production, and aquaporin 5 downregulation through suppressing the NF kappaB pathway in human nasal epithelial cells. AB - Allergic rhinitis (AR) is a chronic respiratory inflammatory disease. Glycyrrhizin is a main bioactive component of the licorice root extract and exhibits anti-inflammatory activity. However, the role of glycyrrhizin in AR has not been studied. The aim of the present study was to investigate the effect of glycyrrhizin on histamine-induced human nasal epithelial cells (HNEpCs). Here, we found that glycyrrhizin (20 or 40 MUM) inhibited histamine-induced the mRNA expression and secretion of mucin 5 subtype AC (MUC5AC), interleukin (IL)-6 and IL-8 in HNEpCs. The expression levels of aquaporin 5 (AQP5) and phosphorylated cyclic adenosine monophosphate-responsive element binding protein (p-CREB) were decreased by histamine in HNEpCs and increased in cells treated with glycyrrhizin. The glycyrrhizin treatment inhibited histamine-induced expressions of p-NF-kappaB p65 and p-IkappaBalpha in HNEpCs, indicating that glycyrrhizin inhibited the activation of NF-kappaB pathway in histamine-induced HNEpCs. In addition, inhibition of the NF-kappaB pathway exhibited the similar effect with glycyrrhizin on histamine-induced HNEpCs. In summary, the results showed that glycyrrhizin reversed the effect of histamine on MUC5AC expression, inflammatory cytokine production, and AQP5 expression in HNEpCs, and the NF-kappaB pathway was involved in the effect. Glycyrrhizin might be used for complementary and alternative therapeutics of AR. PMID- 29452069 TI - Idiopathic Isolated Unilateral Hypoglossal Nerve Palsy: A Report of 2 Cases and Review of the Literature. AB - Hypoglossal nerve palsy (HNP) is a common finding in neurologic diseases when associated with other cranial nerve palsies or further pathology and exhibits characteristic clinical manifestations, including unilateral atrophy of the musculature of the tongue. It occasionally appears as the initial or solitary sign of an intracranial or extracranial space-occupying lesion, head or neck injury, or vascular abnormality of the internal carotid artery. There are few cases of idiopathic isolated unilateral HNP, which should be diagnosed through exclusion. This report describes 2 patients who had different outcomes and presents a literature review of idiopathic isolated unilateral HNP. Case 1 was a 71-year-old man who was referred with a 1-month history of dysphagia and speech impairment. Intraoral examination disclosed marked left-side hemiatrophy of the tongue and deviation toward the left on protrusion. At coronal Tl-weighted magnetic resonance imaging, left-side hemiatrophy of the tongue was clearly visible through deviation of the median septum to the left. The patient was diagnosed with idiopathic isolated unilateral HNP through exclusion and was treated with steroids and mecobalamin, but he did not recover. Case 2 was a 32 year-old man complaining of tongue weakness for 2 days. On examination, left HNP was evident, with deviation of the tongue to the left on protrusion. He was diagnosed with idiopathic isolated unilateral HNP through exclusion and was treated with steroids. After 3 weeks, the patient had completely recovered. To the best of the authors' knowledge, this is the first detailed literature review on idiopathic isolated unilateral HNP. This condition is very rare but should be considered for diagnosis. It warrants a thorough and stepwise approach for etiologic diagnosis. PMID- 29452070 TI - A Modified Peri-Angular Approach for Exposure of Condylar Fractures. AB - PURPOSE: To describe a modified peri-angular approach to address subcondylar and condylar neck fractures. MATERIALS AND METHODS: A modified peri-angular incision is used to approach a fractured condyle through the anteroparotid transmasseteric approach. RESULTS: In the authors' experience, this method provides quick and clean exposure to the fractured condylar base and neck fractures for open reduction and internal fixation. CONCLUSION: Although the peri-angular approach has been discussed in the literature, the authors' modification lessens the chance of complications, such as marginal nerve injury and parotid fistula formation, because the nerve is visualized and kept isolated throughout.

PMID- 29452071 TI - CaMKII inhibition ameliorated levodopa-induced dyskinesia by downregulating tyrosine hydroxylase activity in an experimental model of Parkinson's disease. AB - Levodopa (L-dopa) remains the best treatment for Parkinson's disease (PD). However, long-term L-dopa treatment induces dyskinesia. The mechanism of L-dopa induced dyskinesia (LID) is not fully understood. Enhanced activity of protein kinase A (PKA) and pulsatile dopamine (DA) stimulation plays an important role in LID. Tyrosine hydroxylase (TH) is the rate-limiting enzyme for DA synthesis. Decreased TH activity causes reduced pulsatile DA stimulation, which in turn reduces LID. Moreover, TH is a substrate of CaMKII. However, it is unknown whether inhibition of CaMKII reduces LID by downregulating the activity of TH. In this study, we found that CaMKII antagonist KN-93 reduced DA released in PC12 cells; in the meantime, KN-93 reduced phosphorylated levels of CaMKIIalpha and TH at Ser 40. Intrastriatal administration of KN-93 reduced LID without affecting the antiparkinsonian effect of L-dopa in PD mice. Mechanistically, KN-93 treatmentreduced phosphorylated CaMKIIalpha levels and subsequently downregulated phosphorylated TH at Ser 40 expression. Consequently, extracellular DA efflux was reduced andthe activation threshold of the PKA pathway was lowered. Moreover, KN 93 treatment reduced the expression of Arc and Penk, two immediate early genes, induced by chronic L-dopa. These data indicate that inhibition of CaMKIIalpha decreases LID at least partially by suppressing TH activity and subsequently reducing extracellular DA efflux and the activity of the PKA pathway, suggesting that CaMKIIalpha may be an alternative target for the treatment of LID. PMID- 29452073 TI - The role of adiponectin and adipolin as anti-inflammatory adipokines in the formation of macrophage foam cells and their association with cardiovascular diseases. AB - Obesity is one of the major public health concerns that is closely associated with obesity-related disorders such as type 2 diabetes mellitus (T2DM), hypertension, and atherosclerosis. Atherosclerosis is a chronic disease characterized by excess cholesterol deposition in the arterial intima and the formation of foam cells. Adipocytokines or adipokines are secreted by the adipose tissue as endocrine glands; adiponectin and adipolin are among these adipokines that are associated with obese and insulin-resistant phenotypes. Adipolin and adiponectin are cytokines that exert substantial impact on obesity, progression of atherosclerosis, insulin resistance, and glucose metabolism. In this paper, we review the formation of macrophage foam cells, which are associated with atherosclerosis, and the macrophage mechanism, which includes uptake, esterification, and release. We also summarize current information on adipose tissue-derived hormone and energy homeostasis in obesity. Finally, the role of adipokines, e.g., adipoline and adiponectin, in regulating metabolic, cardiovascular diseases is discussed. PMID- 29452075 TI - Physiological correlates of reproductive decisions: Relationships among body condition, reproductive status, and the hypothalamus-pituitary-adrenal axis in a reptile. AB - When opportunities to feed and reproduce are limited, females are often unable to recover sufficient energy stores to reproduce in consecutive years. Body condition has been used as a proxy for recent reproductive history in such species. We previously found that glucocorticoid responses to capture stress vary with body condition in female red-sided garter snakes (Thamnophis sirtalis parietalis), a species with limited seasonal breeding opportunities. Because variation in glucocorticoid receptor (GR) protein in the brain could explain these differences, we first assessed GR protein content in females in different body conditions. To investigate if body condition during the spring mating season accurately reflects recent reproductive history, we measured glucocorticoid responses to stress in females with different body conditions, assessed their mating behavior and brought mated females to our lab to determine which females would give birth during the summer (i.e., were parturient). Female red-sided garter snakes reproduce biennially, and therefore mated females that did not give birth were deemed non-parturient. In this study, glucocorticoid stress responses and mating behavior did not vary with body condition, nor was body condition related to brain GR or reproductive condition (parturient vs non-parturient). Only unreceptive females showed a significant stress-induced increase in glucocorticoids, suggesting that reduced stress responsiveness is associated with receptivity. Parturient females mated faster (were more proceptive) than non parturient females. These data suggest that HPA axis activity modulates receptivity, while proceptivity is related primarily to reproductive condition. PMID- 29452076 TI - Feasibility of EUS-guided Nd:YAG laser ablation of unresectable pancreatic adenocarcinoma. AB - BACKGROUND AND AIMS: EUS has become an interventional technique in which a needle may be used as a vehicle to deliver therapeutic agents. Laser ablation (LA) has been used to treat many primary and secondary neoplasms. This study aimed to assess the feasibility of EUS-guided LA for unresectable (UR) pancreatic cancer. METHODS: Patients with stage IIb-III pancreatic cancer underwent EUS-guided LA. All patients were unresponsive to previous chemoradiotherapy. LA was performed by using a 300-MUm flexible fiber preloaded onto a 22-gauge fine needle. A 1064-nm wavelength neodymium-yttrium aluminum garnet (Nd:YAG) laser light with different power settings of 2 W for 800 J, 1000 J, and 1200 J; 3 W for 800 J, 1000 J, and 1200 J; and 4 W for 800 J, 1000 J, and 1200 J was used. Each patient was treated with a single application of 1 of these settings. The application time of the power settings ranged from 200 to 600 seconds. RESULTS: Nine patients (median age, 74.7; range 55-85) underwent Nd:Yag LA. The mean size of the focal lesion was 35.4 mm (range, 21-45). The ablation area, demonstrated by 24-hour CT, ranged from .4 cm3 (for the lower power setting of 2 W/800 J) to a maximum of 6.4 cm3 (for 4 W/1000 J). The procedure was completed in all 9 patients without adverse events. CONCLUSION: In our human experience, EUS-guided LA was feasible and well tolerated in patients with UR pancreatic cancer.

Estrogens exert pleiotropic effects on multiple physiological and behavioral traits including sexual behavior. These effects are classically mediated via binding to nuclear receptors and subsequent regulation of target gene transcription. Estrogens also affect neuronal activity and cell-signaling pathways via faster, membrane initiated events. Although the distinction between appetitive and consummatory aspects of sexual behavior has been criticized, this distinction remains valuable in that it facilitates the causal analysis of certain behavioral systems. Effects of neuroestrogens produced by neuronal aromatization of testosterone on copulatory performance (consummatory aspect) and on sexual motivation (appetitive aspect) are described in male quail. The central administration of estradiol rapidly increases expression of sexual motivation, as assessed by two measures of sexual motivation produced in response to the visual presentation of a female but not sexual performance in male Japanese quail. This effect is mimicked by membrane-impermeable analogs of estradiol, indicating that it is initiated at the cell membrane. Conversely, blocking the action of estrogens or their synthesis by a single intracerebroventricular injection of estrogen receptor antagonists or aromatase inhibitors, respectively, decreases sexual motivation within minutes without affecting performance. The same steroid has thus evolved complementary mechanisms to regulate different behavioral components (motivation vs. performance) in distinct temporal domains (long- vs. short-term) so that diverse reproductive activities can be properly coordinated. Changes in preoptic aromatase activity and estradiol as well as glutamate concentrations are observed during or immediately after copulation. The interaction between these neuroendocrine/neurochemical changes and their functional significance is discussed.

AB - BACKGROUND AND AIMS: Although colonic perforation is a dreadful adverse event associated with stent placement, data on this topic are sparse. We aimed to investigate the clinical outcomes of colonic perforation and factors related to its occurrence in patients who received self-expandable metal stents (SEMSs) for malignant colorectal obstruction. METHODS: We retrospectively reviewed the data of 474 patients with malignant colorectal obstruction who received endoscopic SEMS insertion from April 2004 to May 2011 in Severance Hospital and Gangnam Severance Hospital. Early perforation, defined as perforation occurring within 2 weeks, was assessed in bridge-to-surgery (n = 164) and palliative stent placement patient groups (n = 310). Delayed perforation was analyzed using data from the palliative stent placement group alone. RESULTS: The technical and clinical success rates were 90.5% and 81.0%, respectively. Early and delayed perforations occurred in 2.7% (13/474) and 2.7% (8/301) of patients, respectively. Among 21 patients with perforation, 14 (66.7%) received emergency surgery and 5 (23.8%) died within 30 days after perforation. Regarding the perforation-related factors, age >=70 years (odds ratio, 3.276; 95% confidence interval [CI], 1.041-10.309) and sigmoid colonic location (odds ratio, 7.706; 95% CI, 1.681-35.317) were independently associated with occurrence of early perforation. Stent location in the flexure (hazard ratio, 17.573; 95% CI, 2.004-154.093) and absence of peritoneal carcinomatosis (hazard ratio, 6.139; 95% CI, 1.150-32.776) were significantly associated with delayed perforation. CONCLUSIONS: The perforation related 30-day mortality rate was 23.8%. Older age and sigmoid colonic location were significantly associated with occurrence of early perforation, whereas flexure location and absence of peritoneal carcinomatosis were related to delayed perforation.

Clinicians suspected thrombotic thrombocytopenic purpura, and the diagnosis was supported by ADAMTS13 testing. The clinicians attempted to place a Quinton catheter for emergent plasmapheresis, but the patient expired before definitive treatment could be initiated. Autopsy was obtained and revealed a right middle lobe consolidation grossly consistent with lymphoid tissue or tumor. PMID- 29452081 TI - Chronic Nosema ceranae infection inflicts comprehensive and persistent immunosuppression and accelerated lipid loss in host Apis mellifera honey bees. AB - Nosema ceranae is an intracellular microsporidian parasite of the Asian honey bee Apis cerana and the European honey bee Apis mellifera. Until relatively recently, A. mellifera honey bees were naive to N. ceranae infection. Symptoms of nosemosis, or Nosema disease, in the infected hosts include immunosuppression, damage to gut epithelium, nutrient and energetic stress, precocious foraging and reduced longevity of infected bees. Links remain unclear between immunosuppression, the symptoms of nutrient and energetic stress, and precocious foraging behavior of hosts. To clarify physiological connections, we inoculated newly emerged A. mellifera adult workers with N. ceranae spores, and over 21 days post inoculation (21 days pi), gauged infection intensity and quantified expression of genes representing two innate immune pathways, Toll and Imd. Additionally, we measured each host's whole-body protein, lipids, carbohydrates and quantified respirometric and activity levels. Results show sustained suppression of genes of both humorally regulated immune response pathways after 6 days pi. At 7 days pi, elevated protein levels of infected bees may reflect synthesis of antimicrobial peptides from an initial immune response, but the lack of protein gain compared with uninfected bees at 14 days pi may represent low de novo protein synthesis. Carbohydrate data do not indicate that hosts experience severe metabolic stress related to this nutrient. At 14 days pi infected honey bees show high respirometric and activity levels, and corresponding lipid loss, suggesting lipids may be used as fuel for increased metabolic demands resulting from infection. Accelerated lipid loss during nurse honey bee behavioral development can have cascading effects on downstream physiology that may lead to precocious foraging, which is a major factor driving colony collapse. PMID- 29452082 TI - Pre-treatment red blood cell distribution width provides prognostic information in multiple myeloma. AB - BACKGROUND: The red blood cell distribution width (RDW), a credible marker for abnormal erythropoiesis, has recently been studied as a prognostic factor in oncology, but its role in multiple myeloma (MM) hasn't been thoroughly investigated. METHODS: We performed a retrospective study in 162 patients with multiple myeloma. Categorical parameters were analyzed using Pearson chi-squared test. The Mann-Whitney and Wilcoxon tests were used for group comparisons. Comparisons of repeated samples data were analyzed with the general linear model repeated-measures procedure. The Kaplan-Meier product-limit method was used to determine OS and PFS, and the differences were assessed by the log-rank test. RESULTS: High RDW baseline was significantly associated with indexes including haemoglobin, bone marrow plasma cell infiltration, and cytogenetics risk stratification. After chemotherapy, the overall response rate (ORR) decreased as RDW baseline increased. In 24 patients with high RDW baseline, it was revealed RDW value decreased when patients achieved complete remission (CR), but increased when the disease progressed. The normal-RDW baseline group showed both longer overall survival (OS) and progression-free survival (PFS) than the high-RDW baseline group. CONCLUSION: Our study suggests pre-treatment RDW level is a prognostic factor in MM and should be regarded as an important parameter for assessment of therapeutic efficiency. PMID- 29452083 TI - Tribolium castaneum gene expression changes after Paranosema whitei infection. AB - BACKGROUND: Microsporidia are obligate parasites that possess some of the smallest eukaryotic genomes. Several insect species are susceptible to infections by microsporidian parasites. Paranosema whitei frequently infects young larvae of Tribolium castaneum and obligately kills the host whereupon transmission to subsequent hosts is accomplished via spores. P. whitei infection results in developmental arrest of T. castaneum, preventing larvae from pupation. The mechanisms underlying P. whitei virulence as well as the molecular underpinning of host defenses remain uncharacterized. In the present study, we evaluated gene expression differences of T. castaneum infected with the microsporidian parasite P. whitei. RESULTS: More than 1500 T. castaneum genes were differentially expressed after infection with P. whitei. Several important host pathways appeared to be differentially expressed after infection, where immune genes were among the highest differential expressed genes. Genes involved in the Toll pathway and its effectors were specifically upregulated. Furthermore, iron homeostasis processes and transmembrane transport appeared significantly altered after P. whitei infection. Kruppel homolog 1 (Kr-h1) and other genes of the juvenile hormone (JH) pathway appeared differentially expressed after parasite infection. In addition, a small number of long intergenic non-coding RNAs (lincRNAs) appeared differentially expressed after P. whitei infection. CONCLUSION: In this study we characterized for the first time using RNA-seq the immune response of T. castaneum to P. whitei. Other pathways (transmembrane transport, iron homeostasis, protein synthesis, JH) indicate possible alterations of the host by the parasite such as a possible developmental arrest caused by JH regulation. Furthermore we find evidence that some lincRNAs might be connected to defense as previously reported for other insect species. PMID- 29452084 TI - Successful reproduction of unmated Tropilaelaps mercedesae and its implication on mite population growth in Apis mellifera colonies. AB - Successful reproduction by unmated Tropilaelaps mercedesae is reported here for the first time. Of the eight mature daughters that did not have male mates within their natal cells, four produced both mature sons and daughters, and four produced mature daughters only. Overall, 78% of the new daughters that had no egg laying experience, and 84% of the foundresses that had or had not laid previously reproduced. Both inoculum daughter and foundress mites were collected from tan bodied pupae and inoculated immediately. Therefore, our results suggest that phoresy is not required for reproduction in tropilaelaps mites. The ability of virgin females to lay both males and females (deuterotoky), and to reproduce without spending a phoretic period on adult bees may play major roles in tropilaelaps mites' competitive advantage over varroa mites in Apis mellifera colonies.

PMID- 29452086 TI - Ameliorative effects of clonidine on ethanol induced kidney injury in rats: Potential role for imidazoline-1 receptor. AB - Chronic alcoholism is a risk factor for kidney injury. Clonidine is an alpha2 adrenergic receptor/imidazoline-1 receptor agonist that can reduce blood pressure and maintain renal functions. This study aims to investigate the possible ameliorative effects of clonidine on ethanol induced kidney injury and its mechanism of action. Kidney injury was induced in rats by adding ethanol to drinking water for eight weeks. Clonidine effects on kidney functions and histopathology were measured. Moreover, phentolamine (alpha-adrenergic receptor antagonist), efaroxan (imidazoline-1 receptor antagonist) and rilmenidine (imidazoline-1 receptor agonist) were used to clarify the role of imidazoline-1 receptor in mediating renal ameliorative effects. Also, the effect of clonidine on liver functions and metabolic changes, in addition to renal oxidative stress, inflammatory and apoptotic pathways were measured. Results showed that, clonidine improved renal functions and reduced ethanol induced renal inflammation and fibrosis. On the other hand, efaroxan, only, blocked clonidine effects on kidney functions. Rilmenidine decreased kidney injury like clonidine. Both clonidine and rilmenidine increased renal nischarin gene expression. Furthermore, clonidine improved liver functions, increased serum insulin and decreased serum advanced glycation end products (metabolic markers). Also, clonidine reduced renal oxidative stress as reflected by decreased myeloperoxidase, malondialdehyde, inducible nitric oxide synthase and total nitric oxide levels and increased superoxide dismutase level. Moreover, clonidine reduced renal tumor necrosis factor-alpha (inflammatory marker) and caspase-3 (apoptotic marker) levels, while increased renal prostaglandine E2 and interleukin-10 levels (anti-inflammatory markers). In conclusion, clonidine can reduce ethanol induced kidney injury, at least in part, by stimulating imidazoline-1 receptor signaling.

PMID- 29452090 TI - Activation of calcium-sensing receptor-mediated autophagy in angiotensinII induced cardiac fibrosis in vitro. AB - Cardiac fibrosis is one of the primary mechanisms of ventricular remodeling, and there is no effective method for reversal. Activation of calcium sensing receptor (CaSR) has been reported to be involved in the development of myocardial fibrosis, but the molecular mechanism for CaSR activation has not yet been clarified and needs to be further explored. Here, we found that AngII induces cardiac fibroblast proliferation and phenotypic transformation in a dose dependent manner with increased CaSR and autophagy related protein (Beclin1, LC3B) expression. CaSR activation results in intracellular calcium release, MEK1/2 pathway phosphorylation, autophagy activation and collagen formation induced by AngII in cardiac fibroblasts. However, pretreating the cells with Calhex231, PD98059 or 3-MA partially blocked AngII-induced cardiac fibrosis. Our data indicate that the activation of CaSR-mediated MEK/ERK and autophagic pathways is involved in AngII-induced cardiac fibrosis in vitro. PMID- 29452091 TI - Expression profiles and clinical value of plasma exosomal Tim-3 and Galectin-9 in non-small cell lung cancer. AB - Exosomes are membrane-bound, virus-sized vesicles present in circulating blood. Tumor cells are avid producers of exosomes, which are thought to mimic molecular features of parent tumor cells. T-cell immunoglobulin- and mucin-domain containing molecule 3 (Tim-3) is a the next-generation immune checkpoint that can be activated by its ligand Galectin-9 to negatively regulate the anti-tumor immune response. However, the characteristics of plasma exosomal Tim-3 and Galectin-9 (Exo-T/G) in cancer remained unknown. This study was conducted to investigate the expression patterns and clinical value of plasma exosomal total protein (Exo-pro) and Exo-T/G in non-small cell lung cancer (NSCLC). Plasma was collected from 103 NSCLC patients including 60 early stages and 43 advanced stages disease samples as well as 56 healthy subjects. Exosomes were isolated from plasma by commercial exosome precipitation solution and identified by western blotting of CD63 and transmission electron microscopy. Exo-pro concentration was measured by the BCA assay. Enzyme-linked immunosorbent assay was used to quantify Exo-T/G. Additionally, 34 NSCLC samples were applied to directly detect plasma TIM-3 (Plas-T) and Galectin-9 (Plas-G). Our results showed that Exo-pro, Exo-T, and Exo-G were significantly increased in NSCLC plasma compared to that in the healthy samples. High levels of Exo-T and Exo-G were all positively correlated with several malignant parameters, including larger tumor size, advanced stages, and more distant metastasis. High levels of Exo-pro and Exo-T were also correlated with more lymph node metastasis. Additionally, plasma from lung squamous cell carcinoma showed higher Exo-T and Exo-G compared with that from lung adenocarcinoma. ALK-positive patients showed to have decreased Exo T and Exo-G levels. Pearson's correlation analysis revealed a significant correlation between Exo-pro and Exo-T/G, Exo-T and Exo-G, Exo-T and Plas-T, Exo-G and Plas-G, and Plas-T and Plas-G. Together, our data revealed that Exo-pro, especially Exo-T and Exo-G could be potential biomarkers for NSCLC. Further studies focusing on pure tumor-derived exosomes isolated from plasma were needed. PMID- 29452092 TI - MicroRNA-630 inhibitor sensitizes chemoresistant ovarian cancer to chemotherapy by enhancing apoptosis. AB - MicroRNA-630 (miR-630) has been implicated in the development and progression of multiple cancers. The current study aimed to investigate the role of miR-630 in chemoresistant epithelial ovarian cancer. MiR-630 expression levels were detected in ovarian cancer cell line SKOV3 and paclitaxel-resistant SKOV3 (SKOV3-TR) via microarray and qRT-PCR. MiR-630 inhibitors and negative controls were transfected into SKOV3 and SKOV3-TR cells. Wound healing, invasion, chemosensitivity, and cell apoptosis assays were performed to determine proliferation and migration rates. Chemoresistant patient-derived xenograft (PDX) models were established and utilized to verify the effect of miR-630 on chemoresistant ovarian cancer. Inhibition of miR-630 decreased cell proliferation and enhanced the sensitivity of SKOV3-TR and SKOV3 cells to paclitaxel. In the chemosensitivity assay, we observed that the miR-630 inhibitor exhibited a synergistic effect with paclitaxel on SKOV3-TR cells. Inhibition was correlated with enhanced expression of apoptosis-related proteins. APAF-1 was predicted to be a potential target of miR-630. An in vivo PDX study showed that the miR-630 inhibitor sensitized chemoresistant ovarian cancer to paclitaxel. Thus, miR-630 inhibitor sensitizes chemoresistant epithelial ovarian cancer to chemotherapy by enhancing apoptosis. Our findings suggest that miR-630 might be a potential therapeutic target for chemotherapy-resistant ovarian cancer. PMID- 29452093 TI - Autophagy inhibition enhances anticancer efficacy of artepillin C, a cinnamic acid derivative in Brazilian green propolis. AB - Propolis, a resinous substance produced by honeybees, possesses various biological actions including anticancer activity towards tumor cells. Recently, the ethanol extract of Brazilian green propolis has been shown to induce autophagy, which is known to be induced in treatment of cancer cells with anticancer drugs, leading to cancer cell survival and decreased sensitivity to anticancer agents. In this study, we aimed to identify autophagy-inducing components of the propolis and elucidated the reciprocal relationship between anticancer cytotoxicity and protective autophagy in prostate cancer CWR22Rv1 cells. Among eight cinnamic acid derivatives [chlorogenic acid, p-coumaric acid, caffeic acid, 3,4-caffeoylquinic acid, artepillin C (ArtC), baccharin, drupanin and caffeic acid phenethyl ester] in propolis, only ArtC showed high autophagy inducing activity accompanying LC3-II upregulation. ArtC was also induced apoptosis as revealed by DNA fragmentation and increases in cleaved caspase-3 and poly ADP-ribose polymerase. The apoptosis induced by ArtC was exacerbated by cotreatment with autophagy inhibitors (chloroquine, wortmannin and U0126). The cotreatment further induced necroptosis accompanying increased expression of receptor-interacting serine/threonine protein kinases 1 and 3. These data indicate that cytotoxicity of ArtC to the prostate cancer cells is dampened by induced autophagy, but is markedly augmented by inhibition of autophagy. Therefore, the combination of ArtC and autophagy inhibitors may be a novel complementary-alternative treatment for prostate cancer. PMID- 29452096 TI - The macrophage heme-heme oxygenase-1 system and its role in inflammation. AB - Heme oxygenase (HO)-1, the inducible isoform of the heme-degrading enzyme HO, plays a critical role in inflammation and iron homeostasis. Regulatory functions of HO-1 are mediated via the catalytic breakdown of heme, which is an iron containing tetrapyrrole complex with potential pro-oxidant and pro-inflammatory effects. In addition, the HO reaction produces the antioxidant and anti inflammatory compounds carbon monoxide (CO) and biliverdin, subsequently converted into bilirubin, along with iron, which is reutilized for erythropoiesis. HO-1 is up-regulated by a plethora of stimuli and injuries in most cell types and tissues and provides salutary effects by restoring physiological homeostasis. Notably, HO-1 exhibits critical immuno-modulatory functions in macrophages, which are a major cell population of the mononuclear phagocyte system. Macrophages play key roles as sentinels and regulators of the immune system and HO-1 in these cells appears to be of critical importance for driving resolution of inflammatory responses. In this review, the complex functions and regulatory mechanisms of HO-1 in macrophages will be high-lighted. A particular focus will be the intricate interactions of HO-1 with its substrate heme, which play a contradictory role in distinct physiological and pathophysiological settings. The therapeutic potential of targeted modulation of the macrophage heme-HO-1 system will be discussed in the context of inflammatory disorders. PMID- 29452095 TI - The role of free-fatty acid receptor-4 (FFA4) in human cancers and cancer cell lines. AB - A dietary influence on cancer progression has been evident for many decades, and dietary fatty acids, particularly long chain mono- and polyunsaturated fatty acids, have been shown to play significant roles in influencing growth of a variety of human cancers. The discovery of the family of cell-surface free-fatty acid receptors, which include the long-chain fatty acid receptors FFA1 and FFA4, suggest that many of the effects of dietary fats could be receptor-mediated. FFA4 is ubiquitously expressed and has recently been shown to modulate a variety of important anti-inflammatory and metabolic processes. Since FFA4 is currently an attractive drug target for treatment of metabolic disorders such as diabetes and obesity, understanding its role in cancer progression is critical towards the drug discovery process. In this research update, the current body of knowledge on the role of this receptor in regulating cancer cell proliferation, migration, and invasion, as well as in vivo tumorigenesis is reviewed. PMID- 29452097 TI - Stimulation of TRPV1 channels activates the AP-1 transcription factor. AB - Transient receptor potential vanilloid 1 (TRPV1) channels were originally described as the receptors of capsaicin, the main constituent of hot chili pepper. The biological functions of TRPV1 channels include pain sensation and inflammatory thermal hyperalgesia. Here, we show that stimulation of HEK293 cells expressing TRPV1 channels (H2C1 cells) with capsaicin or the TRPV1 ligand resiniferatoxin activated transcription mediated by the transcription factor AP 1. No cell death was occurring under these experimental conditions. The AP-1 activity was not altered in capsaicin or resiniferatoxin-stimulated HEK293 cells lacking TRPV1. We identified the AP-1 DNA binding site as the capsaicin/resiniferatoxin-responsive element. Stimulation with the TRPV1 ligand N arachidonoyldopamine increased AP-1 activity in a TRPV1-dependent and TRPV1 independent manner. Stimulation of TRPV1 channels induced an influx of Ca2+ into the cells and this rise in intracellular Ca2+ was essential for activating AP-1 in capsaicin or resiniferatoxin-stimulated cells. N-arachidonoyldopamine stimulation induced a rise in intracellular Ca2+ in a TRPV-1 dependent and independent manner. AP-1 is a dimeric transcription factor, composed of proteins of the c-Jun, c-Fos and ATF families. Stimulation of TRPV1 channels with capsaicin increased c-Jun and c-Fos biosynthesis in H2C1 cells. The signal transduction of capsaicin, leading to enhanced AP-1-mediated transcription, required extracellular signal-regulated protein kinase ERK1/2 as a signal transducer and the activation of the transcription factors c-Jun and ternary complex factor. Together, these data suggest that the intracellular functions of TRPV1 stimulation may rely on the activation of a stimulus-regulated protein kinase and stimulus-responsive transcription factors. PMID- 29452098 TI - Features of COPD as Predictors of Lung Cancer. AB - BACKGROUND: Lung cancer is a leading cause of death and hospitalization for patients with COPD. A detailed understanding of which clinical features of COPD increase risk is needed. METHODS: We performed a nested case-control study of Genetic Epidemiology of COPD (COPDGene) Study subjects with and without lung cancer, age 45 to 80 years, who smoked at least 10-pack years to identify clinical and imaging features of smokers, with and without COPD, that are associated with an increased risk of lung cancer. The baseline evaluation included spirometry, high-resolution chest CT scanning, and respiratory questionnaires. New lung cancer diagnoses were identified over 8 years of longitudinal follow-up. Cases of lung cancer were matched 1:4 with control subjects for age, race, sex, and smoking history. Multiple logistic regression analyses were used to determine features predictive of lung cancer. RESULTS: Features associated with a future risk of lung cancer included decreased FEV1/FVC (OR, 1.28 per 10% decrease [95% CI, 1.12-1.46]), visual severity of emphysema (OR, 2.31, none-trace vs mild-advanced [95% CI, 1.41-3.86]), and respiratory exacerbations prior to study entry (OR, 1.39 per increased events [0, 1, and >= 2] [95% CI, 1.04-1.85]). Respiratory exacerbations were also associated with small-cell lung cancer histology (OR, 3.57 [95% CI, 1.47-10]). CONCLUSIONS: The degree of COPD severity, including airflow obstruction, visual emphysema, and respiratory exacerbations, was independently predictive of lung cancer. These risk factors should be further studied as inclusion and exclusion criteria for the survival benefit of lung cancer screening. Studies are needed to determine if reduction in respiratory exacerbations among smokers can reduce the risk of lung cancer. PMID- 29452099 TI - A Systematic Review and Meta-Analysis Comparing Pigtail Catheter and Chest Tube as the Initial Treatment for Pneumothorax. AB - BACKGROUND: The optimal initial treatment approach for pneumothorax remains controversial. This systemic review and meta-analysis investigated the effectiveness of small-bore pigtail catheter (PC) drainage compared with that of large-bore chest tube (LBCT) drainage as the initial treatment approach for all subtypes of pneumothorax. METHODS: PubMed and Embase were systematically searched for observational studies and randomized controlled trials published up to October 9, 2017, that compared PC and LBCT as the initial treatment for pneumothorax. The investigative outcomes included success rates, recurrence rates, complication rates, drainage duration, and hospital stay. RESULTS: Of the 11 included studies (875 patients), the success rate was similar in the PC (79.84%) and LBCT (82.87%) groups, with a risk ratio of 0.99 (95% CI, 0.93 to 1.05; I2 = 0%). Specifically, PC drainage was associated with a significantly lower complication rate following spontaneous pneumothorax than LBCT drainage (Peto odds ratio: 0.49 [95% CI, 0.28 to 0.85]; I2 = 29%). In the spontaneous subgroup, PC drainage was associated with a significantly shorter drainage duration (mean difference, -1.51 [95% CI, -2.93 to -0.09]) and hospital stay (mean difference: -2.54 [95% CI, -3.16 to -1.92]; P < .001) than the LBCT group. CONCLUSIONS: Collectively, results of the meta-analysis suggest PC drainage may be considered as the initial treatment option for patients with primary or secondary spontaneous pneumothorax. Ideally, randomized controlled trials are needed to compare PC vs LBCT among different subgroups of patients with pneumothorax, which may ultimately improve clinical care and management for these patients.

PMID- 29452100 TI - A New, Noninvasive Method of Measuring Impaired Pulmonary Gas Exchange in Lung Disease: An Outpatient Study. AB - BACKGROUND: It would be valuable to have a noninvasive method of measuring impaired pulmonary gas exchange in patients with lung disease and thus reduce the need for repeated arterial punctures. This study reports the results of using a new test in a group of outpatients attending a pulmonary clinic. METHODS: Inspired and expired partial pressure of oxygen (PO2) and Pco2 are continually measured by small, rapidly responding analyzers. The arterial PO2 is calculated from the oximeter blood oxygen saturation level and the oxygen dissociation curve. The PO2 difference between the end-tidal gas and the calculated arterial value is called the oxygen deficit. RESULTS: Studies on 17 patients with a variety of pulmonary diseases are reported. The mean +/- SE oxygen deficit was 48.7 +/- 3.1 mm Hg. This finding can be contrasted with a mean oxygen deficit of 4.0 +/- 0.88 mm Hg in a group of 31 normal subjects who were previously studied (P < .0001). The analysis emphasizes the value of measuring the composition of alveolar gas in determining ventilation-perfusion ratio inequality. This factor is largely ignored in the classic index of impaired pulmonary gas exchange using the ideal alveolar PO2 to calculate the alveolar-arterial oxygen gradient. CONCLUSIONS: The results previously reported in normal subjects and the present studies suggest that this new noninvasive test will be valuable in assessing abnormal gas exchange in the clinical setting.

PMID- 29452101 TI - Cytokine Signaling Protein 3 Deficiency in Myeloid Cells Promotes Retinal Degeneration and Angiogenesis through Arginase-1 Up-Regulation in Experimental Autoimmune Uveoretinitis. AB - The suppressor of cytokine signaling protein 3 (SOCS3) critically controls immune cell activation, although its role in macrophage polarization and function remains controversial. Using experimental autoimmune uveoretinitis (EAU) as a model, we show that inflammation-mediated retinal degeneration is exaggerated and retinal angiogenesis is accelerated in mice with SOCS3 deficiency in myeloid cells (LysMCre/+SOCS3fl/fl). At the acute stage of EAU, the population of infiltrating neutrophils was increased and the population of macrophages decreased in LysMCre/+SOCS3fl/fl mice compared with that in wild-type (WT) mice. Real-time RT-PCR showed that the expression of tumor necrosis factor-alpha, IL 1beta, interferon-gamma, granulocyte-macrophage colony-stimulating factor, and arginase-1 was significantly higher in the LysMCre/+SOCS3fl/fl EAU retina in contrast to the WT EAU retina. The percentage of arginase-1+ infiltrating cells was significantly higher in the LysMCre/+SOCS3fl/fl EAU retina than that in the WT EAU retina. In addition, bone marrow-derived macrophages and neutrophils from the LysMCre/+SOCS3fl/fl mice express significantly higher levels of chemokine (C C motif) ligand 2 and arginase-1 compared with those from WT mice. Inhibition of arginase using an l-arginine analog amino-2-borono-6-hexanoic suppressed inflammation-induced retinal angiogenesis without affecting the severity of inflammation. Our results suggest that SOCS3 critically controls the phenotype and function of macrophages and neutrophils under inflammatory conditions and loss of SOCS3 promotes the angiogenic phenotype of the cells through up regulation of arginase-1. PMID- 29452103 TI - Analysis of 13C labeling amino acids by capillary electrophoresis - High resolution mass spectrometry in developing flaxseed. AB - In context of fluxomic studies, 13C labeling analysis of amino acids are very important for solving the carbon flow calculation, because they are synthesized in various biosynthesis pathways and cellular compartments in plant cells. Traditionally, 13C labeling analysis are performed using low resolution mass spectrometry detector by GC-MS. We compared a method using capillary electrophoresis-high resolution mass spectrometry without derivatization and with better accuracy assessment of labeling measurements comparing to classical GC-MS. Our method allowed us to show that valine, leucine, alanine are not synthesized from the same pyruvate pool during the period of reserves accumulation in flax seeds. PMID- 29452104 TI - Improved protein determination assays obtained after substitution of copper sulfate by copper oxide nanoparticles. AB - Copper oxide nanoparticles (nano CuO) provide Cu2+ ions which can be easily harnessed for protein determination as an alternative to the use of copper sulfate (CuSO4). In the present work, nano CuO of size <25 nm were substituted for CuSO4 in two of the well-known protein assays viz. Lowry method and bicinchoninic acid (BCA) method. Use of nano CuO in the Lowry's assay had no effect on the assay time (30 min) but significantly lowered the limit of detection (LOD) from 0.01 to 0.001 MUg/ml, while the BCA method when performed using nano CuO resulted in notable reduction of not only the assay time from 30 to 20 min but also the LOD from 0.1 to 0.001 MUg/ml. Nano CuO based protein determination in the human serum and urd bean seeds extract produced reliable, reproducible and consistent results. Nano CuO also alleviated the inhibition of both the methods by common interfering substances such as ammonium sulfate, glucose, EDTA, SDS, Triton X-100, dithiothreitol and 2-mercaptoethanol. Hence, successful modification and improvement of Lowry and BCA methods by substitution of CuSO4 with nano CuO for protein determination has been demonstrated.

AB - Sensitive and accurate detection of tumor markers is critical to early diagnosis, point-of-care and portable medical supervision. Alpha fetoprotein (AFP) is an important clinical tumor marker for hepatocellular carcinoma (HCC), and the concentration of AFP in human serum is related to the stage of HCC. In this paper, a label-free electrochemical aptasensor for AFP detection was fabricated using AFP-aptamer as the recognition molecule and thionin/reduced graphene oxide/gold nanoparticles (TH/RGO/Au NPs) as the sensor platform. With high electrocatalytic property and large specific surface area, RGO and Au NPs were employed on the screen-printed carbon electrode to load TH molecules. The TH not only acted as a bridging molecule to effectively capture and immobilize AFP aptamer, but as the electron transfer mediator to provide the electrochemical signal. The AFP detection was based on the monitoring of the electrochemical current response change of TH by the differential pulse voltammetry. Under optimal conditions, the electrochemical responses were proportional to the AFP concentration in the range of 0.1-100.0 MUg/mL. The limit of detection was 0.050 MUg/mL at a signal-to-noise ratio of 3. The proposed method may provide a promising application of aptamer with the properties of facile procedure, low cost, high selectivity in clinic. PMID- 29452106 TI - Nerve fibre layer degeneration and retinal ganglion cell loss long term after optic nerve crush or transection in adult mice. AB - We have investigated the long term effects of two different models of unilateral optic nerve (ON) lesion on retinal ganglion cells (RGCs) and their axons, in the injured and contralateral retinas of adult albino mice. Intact animals were used as controls. The left ON was intraorbitally crushed or transected at 0.5 mm from the optic disk and both retinas were analyzed at 2, 3, 5, 7, 14, 30, 45 or 90 days after injury. RGCs were immunoidentified with anti-Brn3a, and their axons with anti-highly phosphorylated axonal neurofilament subunit H (pNFH). After both lesions, RGC death in the injured retinas is first significant at day 3, and progresses quickly up to 7 days slowing down till 90 days. In the same retinas, the anatomical loss of RGC axons is not evident until day 30. However, by two days after both lesions there are changes in the expression pattern of pNFH: axonal beads, axonal club- or bulb-like formations, and pNFH+RGC somas. The number of pNFH+RGC somata peak at day 5 after either lesion and is significantly higher than in intact retinas at all time points. pNFH+RGC somata are distributed across the retina, in accordance with the pattern of RGC death which is diffuse and homogenous. In the contralateral retinas there is no RGC loss, but there are few pNFH+RGCs from day 2 to day 90. In conclusion, in albino mice, axotomy induced RGC death precedes the loss of their intraretinal axons and occurs in two phases, a rapid and a slower, but steady, one. Injured retinas show similar changes in the pattern of pNFH expression and a comparable course of RGC loss. PMID- 29452094 TI - Evolving mechanisms of vascular smooth muscle contraction highlight key targets in vascular disease. AB - Vascular smooth muscle (VSM) plays an important role in the regulation of vascular function. Identifying the mechanisms of VSM contraction has been a major research goal in order to determine the causes of vascular dysfunction and exaggerated vasoconstriction in vascular disease. Major discoveries over several decades have helped to better understand the mechanisms of VSM contraction. Ca2+ has been established as a major regulator of VSM contraction, and its sources, cytosolic levels, homeostatic mechanisms and subcellular distribution have been defined. Biochemical studies have also suggested that stimulation of Gq protein coupled membrane receptors activates phospholipase C and promotes the hydrolysis of membrane phospholipids into inositol 1,4,5-trisphosphate (IP3) and diacylglycerol (DAG). IP3 stimulates initial Ca2+ release from the sarcoplasmic reticulum, and is buttressed by Ca2+ influx through voltage-dependent, receptor operated, transient receptor potential and store-operated channels. In order to prevent large increases in cytosolic Ca2+ concentration ([Ca2+]c), Ca2+ removal mechanisms promote Ca2+ extrusion via the plasmalemmal Ca2+ pump and Na+/Ca2+ exchanger, and Ca2+ uptake by the sarcoplasmic reticulum and mitochondria, and the coordinated activities of these Ca2+ handling mechanisms help to create subplasmalemmal Ca2+ domains. Threshold increases in [Ca2+]c form a Ca2+ calmodulin complex, which activates myosin light chain (MLC) kinase, and causes MLC phosphorylation, actin-myosin interaction, and VSM contraction. Dissociations in the relationships between [Ca2+]c, MLC phosphorylation, and force have suggested additional Ca2+ sensitization mechanisms. DAG activates protein kinase C (PKC) isoforms, which directly or indirectly via mitogen-activated protein kinase phosphorylate the actin-binding proteins calponin and caldesmon and thereby enhance the myofilaments force sensitivity to Ca2+. PKC-mediated phosphorylation of PKC-potentiated phosphatase inhibitor protein-17 (CPI-17), and RhoA-mediated activation of Rho-kinase (ROCK) inhibit MLC phosphatase and in turn increase MLC phosphorylation and VSM contraction. Abnormalities in the Ca2+ handling mechanisms and PKC and ROCK activity have been associated with vascular dysfunction in multiple vascular disorders. Modulators of [Ca2+]c, PKC and ROCK activity could be useful in mitigating the increased vasoconstriction associated with vascular disease. PMID- 29452107 TI - Trabecular meshwork morphogenesis: A comparative analysis of wildtype and anterior segment dysgenesis mouse models. AB - The trabecular meshwork (TM), a tissue residing in the iridocorneal angle of the eye, is the primary site of aqueous humor outflow and often develops abnormally in children with anterior segment dysgenesis (ASD). However, the cellular mechanisms underlying both normal and pathophysiological TM formation are poorly understood. Here, we improve the characterization of TM development via morphological and molecular analyses. We first assessed the TM of wild-type C57BL/6J mice at multiple time points throughout development (E15.5-P21). The morphology of TM cells, rate of cell division, presence of apoptotic cell death, and age of onset of an established TM marker (alphaSMA) were each assessed in the developing iridocorneal angle. We discovered that TM cells are identifiable histologically at P1, which coincided with both the onset of alphaSMA expression and a significant decrease in TM precursor cell proliferation. Significant apoptotic cell death was not detected during TM development. These findings were then used to assess two mouse models of ASD. Jag1 and Bmp4 heterozygous null mice display ASD phenotypes in the adult, including TM hypoplasia and corneal adherence to the iris. We further discovered that both mutants exhibited similar patterns of developmental TM dysgenesis at P1, P5, and P10. Our data indicate that P1 is an important time point in TM development and that TM dysgenesis in Jag1 and Bmp4 heterozygous null mice likely results from impaired TM cell migration and/or differentiation. PMID- 29452109 TI - Dengue infection in patients with febrile illness and its relationship to climate factors: A case study in the city of Jeddah, Saudi Arabia, for the period 2010 2014. AB - Dengue is an important global arboviral disease with expanding geographical range. It is a major public health concern in Western Saudi Arabia since its first detection in the city of Jeddah in 1994. In this retrospective study, we examined dengue incidence among febrile patients suspected for acute dengue infection at King Abdulaziz University Hospital, Jeddah from 2010 to 2014 and we tried to determine the effect of climate factors on dengue incidence in the city. Acute dengue incidence rates among clinically suspected patients showed annual variation with a range from 29.3% to 57%. Male gender and 11-30 years age range were found to be risk factors for dengue infection in Jeddah. While dengue infections can be detected throughout the year, most cases occurred between March and July with peaks in May and June. Seasonality of dengue was found to be significantly associated with the decrease in relative humidity and increase in temperature within the range of ~25 degrees C to ~33 degrees C but not extremely hot temperatures. Moreover, we found that rainfall during winter (November to February) has a significant lag effect on dengue infection among febrile patients in the city. Jeddah is the second largest city in Saudi Arabia and a major hub for pilgrims because of its close proximity to the holy sites in the Kingdom. The observed high rates of acute dengue infections clearly show the endemicity of dengue in Jeddah. The observed higher incidence rates at young age are expected to cause an increase in severe dengue cases in the future especially that multiple dengue serotypes are co-circulating in the city. Furthermore, the significant association between the different climate factors and dengue and their impact on the disease seasonality should help in the effort to implement effective control and management measures to reduce dengue burden in the Kingdom. PMID- 29452108 TI - Effect of brimonidine, an alpha2 adrenergic agonist, on human meibomian gland epithelial cells. AB - We recently discovered that the anti-glaucoma pharmaceuticals timolol, a beta adrenergic antagonist, and pilocarpine, a cholinergic compound, negatively influence the morphology, proliferative capacity and survival of human meibomian gland epithelial cells (HMGECs). We hypothesize that another class of anti glaucoma drugs, the alpha2 adrenergic agonists, also acts directly on HMGECs to affect their structure and function. We tested this hypothesis. Immortalized (i) HMGECs were cultured with brimonidine, as well as clonidine (alpha2 agonist), phenylephrine (alpha1 agonist), RX821002 (inverse alpha2 agonist) and MK912 (neutral alpha2 agonist) for up to 7 days. Cells were counted with a hemocytometer, and evaluated for morphology, signaling pathway activity, protein biomarker expression, and the accumulation of neutral lipids, phospholipids and lysosomes. Our findings demonstrate that brimondine treatment induces a dose dependent decrease in Akt signaling and proliferation of iHMGECs. In contrast, brimonidine also promotes a dose-dependent differentiation of iHMGECs, including an increase in neutral lipid, phospholipid and lysosome levels. These effects were paralleled by an inhibition of p38 signaling, and duplicated by cellular exposure to clonidine, but not phenylephrine. Brimonidine also enhanced the cellular content of sterol regulatory binding protein-1, a master regulator of lipid synthesis. Of particular interest, the putative alpha2 antagonists, RX821002 and MK912, did not interfere with brimonidine action, but rather stimulated IHMGEC differentiation. Our results support our hypothesis and demonstrate that alpha2 adrenergic agonists act directly on iHMGECs. However, these compounds do not elicit an overall negative effect. Rather, the alpha2 agonists promote the differentiation of iHMGECs.

AB - House is the major site for malaria infection where most human-vector contact takes place. Hence, improving housing might reduce the risk of malaria infection by limiting house entry of vectors. This study aimed to explore the impact of screening doors and windows with wire meshes on density and entomological inoculation rate (EIR) of malaria vector, and malaria incidence, and assess the acceptability, durability, and cost of the intervention. The susceptibility status of malaria vector was also assessed. A two-arm randomized trial was done in Arba Minch Town, southwest Ethiopia. 92 houses were randomly included in the trial. The baseline entomological and malaria prevalence data were collected. The mosquito sampling was done twice per household per month by Centers for Diseases Control and Prevention (CDC) light traps for six months. The baseline prevalence of malaria was assessed by testing 396 (83% of the 447 study participants) household members in all the eligible houses. The 92 houses were then randomized into control and intervention groups using mosquito and malaria prevalence baseline data to make the two groups comparable except the intervention. Then, we put wire-mesh on doors and windows of 46 houses. Post-screening mosquito collection was done in each household twice per month for three months. Each household member was visited twice per month for six months to assess malaria episodes. The frequency of damage to different structure of screening was measured twice. In-depth interview was conducted with 24 purposely selected household heads from intervention group. Speciation of Anopheles mosquito was done by morphological key, and the circum-sporozoite proteins (CSPs) analysis was done using enzyme-linked immunosorbent assay. A generalized estimating equation with a negative binomial distribution was used to assess the impact of the intervention on the indoor density of vectors. Clinical malaria case data were analyzed using Poisson regression with generalized linear model. Screening doors and windows reduced the indoor density of An. arabiensis by 48% (mean ratio of intervention to control = 0.85/1.65; 0.52) (P = .001). Plasmodium falciparum CSP rate was 1.6% (3/190) in the intervention houses, while it was 2.7% (10/372) in the control houses. The protective efficacy of screening intervention from CSP positive An. arabiensis was 41% (mean ratio of intervention to control = 1.6/2.7; 0.59), but was not statistically significant (P = .6). The EIR of An. arabiensis was 1.91 in the intervention group, whereas it was 6.45 in the control group. 477 participants were followed for clinical malaria (50.1% from intervention and 49.9% from the control group). Of 49 RDT positive cases, 45 were confirmed to be positive with microscopy. 80% (n = 36) cases were due to P. falciparum and the rest 20% (n = 9) were due to P. vivax. The incidence of P. falciparum in the intervention group was lower (IRR: 0.39, 95% CI: 0.2-0.80; P = .01) than in the control group. Using incidence of P. falciparum infection, the protective efficacy of intervention was 61% (95% CI: 18-83; P = .007). 97.9% of screened windows and 63.8% of screened doors were intact after eleven months of installation. Malaria mosquito was resistance (mortality rate of 75%) to the insecticide used for bed nets treatment. Almost all participants of intervention arm were willing to continue using screened doors and windows. Screening doors and windows reduced the indoor exposure to malaria vectors. The intervention is effective, durable and well-accepted. Hence, the existing interventions can be supplemented with house screening intervention for further reduction and ultimately elimination of malaria by reducing insecticide pressure on malaria vectors. However, further research could be considered in broad setting on different housing improvement and in the way how to scale-up for wider community. PMID- 29452111 TI - Recent progress in drug targets and inhibitors towards combating leishmaniasis. AB - Lesihmaniasis is one of the major neglected tropical disease caused by the parasite of the genus Leishmania. The disease has more than one clinical forms and the visceral form is considered fatal. With the lack of potential vaccine, chemotherapy is the major treatment source considered for the control of the disease in the infected people. Drugs including amphotericin B and miltefosine are widely used for the treatment, however, development of resistance by the parasite towards the administered drug and high-toxicity of the drug are of major concern. Hence, more attention has been shown on identifying new targets, effective inhibitors, and better drug delivery system against the disease. This review deals with recent studies on drug targets and exploring their essentiality for the survival of Leishmania. Further, new inhibitors for those targets, novel anti-leishmanial peptides and vaccines against leishmaniasis were discussed. We believe that this pool of information will ease the researchers to gain knowledge and help in choosing right targets and design of new inhibitors against Leishmaniasis. PMID- 29452112 TI - Molecular diagnosis of protozoan parasites by Recombinase Polymerase Amplification. AB - Infections caused by protozoan parasites affect millions of people around the world. Traditionally, diagnosis was made by microscopy, which is insensitive and in some cases not specific. Molecular methods are highly sensitive and specific, but equipment costs and personnel training limit its availability only to specialized centers, usually far from populations with the highest risk of infection. Inexpensive methods that can be applied at the point of care (POC), especially in places with limited health infrastructure, would be a major advantage. Isothermal amplification of nucleic acids does not require thermocyclers and is relatively inexpensive and easy to implement. Among isothermal methods, recombinase polymerase amplification (RPA) is sensitive and potentially applicable at POC. We and others have developed RPA diagnostic tests to detect protozoan parasites of medical importance. Overall, our results have shown high specificity with limits of detection similar to PCR. Currently, the optimization of RPA for use at the POC is under development, and in the near future the tests should become available to detect protozoan infections in the field. In this review we discuss the current status, challenges, and future of RPA in the field of molecular diagnosis of protozoan parasites. PMID- 29452113 TI - Technological innovation strategies for the specific treatment of Chagas disease based on Benznidazole. AB - Caused by Trypanosoma cruzi, Chagas disease is responsible for public health problems greater in magnitude than those attributed to malaria, schistosomiasis, or leishmaniasis. A factor in the socioeconomic development of poor countries, Chagas disease can cause death due to a high parasitic burden during its acute phase due and irreversible damage in organs such as the heart, esophagus, and colon during its chronic phase, even when the number of parasites is minimal. For treating Chagas disease, benznidazole (BNZ) remains the drug of choice and, in Latin America, the only drug on the market for treating the disease. However, BNZ has exhibited insufficient activity in the chronic phase of Chagas disease, required administration in large doses, prolonged treatment, and shown a high incidence of adverse reactions (vomiting, rash, peripheral neuropathy, and spinal cord depression), toxicity, and low solubility in water. As an antidote, pharmaceutical technologies have been introduced that can improve BNZ's solubility and dissolution, as well as reduce side effects in light of its bioavailability, all of which can enhance therapy for Chagas disease. In response to that trend, by conducting a literature review, we sought to identify current pharmaceutical technologies used in tandem with BNZ to improve therapy for Chagas disease. Documented techniques include emulsion and microemulsion formation, solutions, parenteral formulas, micronization, and drug delivery systems supported by the development of nanoparticles and cyclodextrins, solid dispersions, and the use of metal-organic frameworks as innovative excipients. Such technologies increase the water solubility of BNZ by 4-25-fold on dissolution and an 85% release with efficacy in only a few minutes, as recorded during a viability experiment with nanoparticle suspensions. That experiment demonstrated the need for a lower concentration of BNZ to kill 50% of trypomastigote forms of T. cruzi, described in terms of the formation of BNZ cyclodextrin complexes, and modulating and vectoring of the antichagasic by using metal-organic frameworks. Altogether, the promising results of research identified can enable strategies to improve solubility and efficacy of BNZ, as well as therapy for Chagas disease. PMID- 29452114 TI - The biodiversity of black flies (Diptera: Simuliidae) in Indonesia. AB - Indonesia is one of the megadiversity country in the world endowed with rich and unique biodiversity insects such as blackflies species (Diptera: Simuliidae). Blackflies are found almost anywhere with running water suitable as habitat for the immature stages. This family is one of the most important groups of blood sucking insects. This study collates the records of Simulium (Diptera: Simuliidae) in previous publications related fauna of Indonesia. Based on the results of this study, there were 124 species of blackflies in Indonesian Archipelago. All species are assigned to the genus Simulium Latreille s.l., and are placed into five subgenera, i.e. Gomphostilbia Enderlein, Morops Enderlein, Nevermannia Enderlein, Simulium Latreille s.str. and Wallacellum Takaoka. Further classification into 27 species groups within the subgenera were also made. Checklists of Indonesian Simuliidae are provided including data on the distribution of each species. PMID- 29452115 TI - Bioprosthetic Versus Mechanical Valve Replacement for Infective Endocarditis: Focus on Recurrence Rates. AB - BACKGROUND: Consensus guidelines for prosthesis selection in infective endocarditis recommend bioprosthetic or mechanical valve replacement based on life expectancy and comorbidity. However, contemporary outcome data are limited to institution series. METHODS: The outcomes of 3,447 patients identified from mandatory discharge databases in California and New York who had either primary isolated mitral (n = 1,603) or aortic (n = 1,844) valve replacement for active endocarditis between 1998 and 2010 were compared according to whether they received bioprosthetic (n = 1,673, 48.5%) or mechanical (n = 1,774, 51.5%) valves. Drug abusers were analyzed as a separate cohort. The primary outcome was endocarditis recurrence. Median follow-up time was 6.8 years (range, 0 to 12). Last follow-up for survival was December 31, 2015. RESULTS: Patients receiving bioprosthetic valves were older (60.4 +/- 14.9 versus 53.4 +/- 14.3 years, p < 0.001), with more comorbidity. There was no significant difference in 12-year survival with bioprosthetic versus mechanical valves after mitral (adjusted hazard ratio 1.14, 95% confidence interval [CI]: 0.98 to 1.34, p = 0.10) or aortic (adjusted hazard ratio 1.10, 95% CI: 0.93 to 1.29, p = 0.26) valve replacement. Bioprosthetic and mechanical valves were associated with similar recurrence rates at 12 years: 10.4% (95% CI: 8.0% to 13.1%) versus 8.8% (95% CI: 6.9% to 10.9%), adjusted Cox p = 0.79 after mitral replacement; and 9.4% (95% CI: 7.5% to 11.6%) versus 10.0% (95% CI: 8.0% to 12.4%), adjusted Cox p = 0.81 after aortic valve replacement. CONCLUSIONS: Bioprosthetic and mechanical valves are associated with similar survival and freedom from endocarditis recurrence. These data support guideline recommendations that patient factors guide prosthesis choice in infective endocarditis. PMID- 29452116 TI - Invited Commentary.

PMID- 29452118 TI - Long-Term Outcome of Interrupted Arch Repair With Direct Anastomosis and Homograft Augmentation Patch. AB - BACKGROUND: This study analyzed outcomes of interrupted aortic arch (IAA) repair using a standardized technique to interpret the role of the arch repair on late outcomes in a complex and heterogeneous group of patients. METHODS: This single institution study covered the period from 1988 to 2015. A total of 120 cases of IAA were divided into four groups: IAA with ventricular septal defect (VSD) (n = 38), IAA with a Norwood or Damus-Kaye-Stansel procedure (n = 41), IAA with truncus arteriosus (n = 24), and a miscellaneous group (n = 17). Arch repair was performed using a standard technique of direct anastomosis with homograft patch augmentation. RESULTS: IAAs were predominantly type B (n = 81, 68%), and type A (n = 34, 28%), with a significant association of type B with truncus arteriosus and of type A with an aortopulmonary window (p < 0.01). Survival was similar in all groups. The incidence of catheter or surgical reintervention was 18% (confidence interval [CI], 10% to 25%) at 5 years and 18% (CI, 10% to 25%) at 10 years, with catheter reintervention more common and occurring before 18 months. Surgical reintervention occurred in 7% (CI, 2% to 13%) at 5 and 10 years and at 10 years the reintervention rate was lower in the group with truncus arteriosus (0%) and in the group with a Norwood or Damus-Kaye-Stansel procedure (5%). There was no bronchial obstruction or aortic aneurysm. The Cox proportional hazard model showed that weight at surgery <2.5 kg and era of surgery were predictive of outcome, with surgical mortality rates in all variants dropping to 8.3% in the last 15 years of the study. CONCLUSIONS: Repair of IAA using direct anastomosis and patch augmentation is applicable to all variants and provides good long-term arch patency. Survival is strongly associated with weight at surgery. PMID- 29452119 TI - MicroRNAs-103/107 Regulate Autophagy in the Epidermis. AB - We have shown that microRNAs-103 and -107 (miRs-103/107) positively regulate end stage autophagy by ensuring dynamin activity in cultured keratinocytes. Most work in end-stage autophagy has been conducted using in vitro model systems. In vivo regulation of end-stage autophagy in epidermis remains unknown. Here, we used antagomirs to subcutaneously knock down miR-107 in the skin; conversely, we delivered miR-107 mimic subcutaneously via in vivo transfection to increase this miR. We found that antagomir-107 treatment in epidermis: (i) depleted endogenous miR-107; (ii) increased GFP-LC3 puncta in epidermal basal layers of GFP-LC3 transgenic mice, indicative of an accumulation of autophagosomes; (iii) inhibited LC3 turnover and increased p62, suggesting an inhibition of autophagy flux; and (iv) increased phosphorylated dynamin (p-dynamin, an inactive form), a key enzyme in end-stage autophagy. Conversely, miR-107 mimic treatment in mouse epidermis: decreased GFP-LC3 puncta in basal layer, as well as p62 protein levels; and diminished p-dynamin, indicative of activation of this enzyme. In human epidermal keratinocytes, antagos-103/107 cause the formation of large vacuoles and an increase in p-dynamin, which can be rescued by inhibition of protein kinase C pathway. Collectively, these results suggest that the miR-103/107 family has a critical role in regulating end-stage autophagy in mouse epidermis via PLD1/2 protein kinase C-dynamin pathway. PMID- 29452120 TI - Quantifying the Polygenic Contribution to Cutaneous Squamous Cell Carcinoma Risk. AB - Genetic factors play an important role in cutaneous squamous cell carcinoma risk. Genome-wide association studies have identified 21 single nucleotide polymorphisms associated with cutaneous squamous cell carcinoma risk. Yet no studies have attempted to quantify the contribution of heritability to cutaneous squamous cell carcinoma risk by calculating the population attributable risk using a combination of all discovered genetic variants. Using an additive multi locus linear logistic model, we determined the cumulative association of these 21 genetic regions to cutaneous squamous cell carcinoma population attributable risk. We computed a multi-locus population attributable risk of 62%, suggesting that if the effects of all the risk alleles were removed from a population, the cutaneous squamous cell carcinoma risk would drop by 62%. Using stratified analysis, we also examined the impact of sex on polygenic risk score, and found that men have an increased relative risk throughout the spectrum of the polygenic risk score. Quantifying the impact of genetic predisposition on the proportion of cancer cases can guide future research decisions and public health policy planning. PMID- 29452121 TI - An Open-Label Pilot Study to Evaluate the Efficacy of Tofacitinib in Moderate to Severe Patch-Type Alopecia Areata, Totalis, and Universalis. AB - Alopecia areata (AA) is a common autoimmune disease with a lifetime risk of ~2%. In AA, the immune system targets the hair follicle, resulting in clinical hair loss. The prognosis of AA is unpredictable, and currently there is no definitive treatment. Our previous whole genome expression studies identified active immune circuits in AA lesions, including common gamma-chain cytokine and IFN pathways. Because these pathways are mediated through JAK kinases, we prioritized clinical exploration of small molecule JAK inhibitors. In preclinical trials in mice, tofacitinib successfully prevented AA development and reversed established disease. In our tofacitinib trial in 12 patients with moderate to severe AA, 11 patients completed a full course of treatment with minimal adverse events. Following limited response to the initial dose (5 mg b.i.d.), the dose was escalated (10 mg b.i.d.) for nonresponding subjects. Eight of 12 patients demonstrated >=50% hair regrowth, while three patients demonstrated <50% hair regrowth, as measured by Severity in Alopecia Tool scoring. One patient demonstrated no regrowth. Gene expression profiles and Alopecia Areata Disease Activity Index scores correlated with clinical response. Our open-label studies of ruxolitinib and tofacitinib have shown dramatic clinical responses in moderate to severe AA, providing strong rationale for larger clinical trials using JAK inhibitors in AA.

AB - Abdominal obesity is even a stronger risk factor than overall obesity for noncommunicable chronic diseases. We examined the association between smoking and abdominal obesity among adolescents. Analyses were based on 38,813 subjects aged 15-17 years from the Study of Cardiovascular Risks in Adolescents (ERICA), a Brazilian school-based national survey. Abdominal obesity was defined considering waist circumference (WC) percentiles. Statistical analyses, stratified by sex, considered the sample complex design. Poisson regression with robust variance was used to estimate smoker-to-nonsmoker abdominal obesity prevalence ratio (PR), adjusting by sociodemographic and lifestyle variables. Higher prevalence of abdominal obesity was observed among adolescents who consumed >1 cigarettes/day, comparing to nonsmokers: considering WC >80th percentile, adjusted-PR for boys was 1.27 [95%CI:1.05,1.52] and, for girls, 1.09 [95%CI:1.00,1.19]; using the 90th percentile, adjusted-PR were 2.24 [95%CI:1.70,2.94] and 1.27 [95%CI:1.12,1.46], respectively for male and female adolescents. Our findings suggest a positive association between cigarette consumption and the prevalence of abdominal obesity, for both boys and girls. Although other studies had found this association in adults, our study contributes to this discussion by assessing it in adolescents using a nationwide representative sample of medium and large municipalities. PMID- 29452125 TI - The creative brain in the figural domain: Distinct patterns of EEG alpha power during idea generation and idea elaboration. AB - This study investigated EEG activity in the upper alpha band during the well known Picture Completion Task of the Torrance Test of Creative Thinking (TTCT), a widely used creative ideation task in the figural domain. The application of a sophisticated computerized version of the TTCT facilitating the online assessment and digitalizing of participant's drawings allowed to separate two central stages of the creative ideation process (i.e., idea generation and idea elaboration). During idea generation, the participants' task was to generate an initial draft of an original and creative completion of the presented abstract lines and figures of the TTCT. During idea elaboration, the participants were required to mentally improve the originality of the initially generated idea/draft. Creative ideation in this figural task was generally associated with comparatively strong desynchronization of upper alpha power over parietal and occipital sites, indicating high visual/figural processing demands. Interestingly, the stage of idea elaboration was accompanied by a relative increase of upper alpha power at parietal and occipital sites compared to the stage of idea generation, indicating heightened top-down processing demands. Furthermore, task performance was associated with relative increases of upper alpha power at frontal sites and relative decreases at centro-temporal sites from the stage of idea generation to idea elaboration. This association suggests the importance of increased inhibitory control over stimulus-based bottom-up information and motor imagery in order to achieve more creative outputs. Taken together these findings add to the relevant literature in that they a) extend research on the relationship between EEG alpha activity and creativity to the figural domain, and b) support a multistage view of creative ideation, involving cognitive control and mental imagery as important components of creativity.

Three hundred and sixty-nine studies were identified, and 18 were included. Specific personality traits, such as Absorption and Self-Transcendence, seem to influence the effects of psychedelics, and psychedelic drug users and nonusers appear to differ in some personality traits. Psychedelics administered in controlled settings may induce personality changes, such as increased Openness and Self-Transcendence. Increases in global brain entropy induced by acute psychedelic administration predicted changes in Openness, and Self-Transcendence was negatively correlated with cortical thinning of the posterior cingulate cortex in long-term religious ayahuasca users. Acute and long-term use of psychedelics is associated with personality changes that appear to be modulated by 5-HT2A receptors. These changes seem to induce therapeutic effects that should be further explored in randomized controlled studies. PMID- 29452128 TI - Are sleep disturbances causally linked to the presence and severity of psychotic like, dissociative and hypomanic experiences in non-clinical populations? A systematic review. AB - The present review aimed to 1) identify what sleep disturbances co-occur alongside psychotic-like, dissociative and hypomanic experiences; 2) assess the strength of potential associations between the severity of sleep disturbances and of the experiences studied; and 3) appraise evidence for a causal link. MedLine and PsycInfo were searched and 44 studies were deemed eligible. Results showed that insomnia was associated with all individual psychotic-like, dissociative and hypomanic experiences reviewed (effect size range: small-to-large). Parasomnias were associated with all psychotic-like experiences; however, there was evidence of variation in magnitude between individual experiences. An eveningness chronotype was associated with dissociative and hypomanic experiences, and circadian dysrhythmia was found alongside hypomania but not the other experiences reviewed. Finally, experimental sleep manipulation studies revealed a potential causal link between sleep loss and psychotic-like and dissociative experiences, although size and consistency of effects varied by specific experience. Future research, using experimental manipulations of sleep to address putative mechanisms, will enable questions of causality to be answered with more confidence. PMID- 29452129 TI - Multicenter initial experience with the EmboTrap device in acute anterior ischemic stroke. AB - BACKGROUND AND PURPOSE: Mechanical thrombectomy predominantly using stent retrievers effectively restores cerebral blood flow and improves functional outcomes in patients with acute ischemic stroke. We sought to determine the safety and efficacy of mechanical thrombectomy using the EmboTrap device. MATERIALS AND METHODS: We identified 80 consecutive patients from 4 centers with acute ischemic stroke treated with EmboTrap from June 2015 to December 2016. All patients had confirmed large vessel occlusions in the anterior circulation using CT or MR angiography with salvageable tissue. We assessed baseline characteristics and treatment related parameters including onset-to-treatment time, recanalization success (mTICI 2b or greater), complications, and good clinical outcome (mRS 0 to 2). RESULTS: Successful recanalization was achieved in 72 patients (90%). When considering the use of a second thrombectomy device as failure, the EmboTrap successfully recanalized 65 patients (81%), with complete (mTICI 3) recanalization in 40 patients (50%) within 1 or 2 passes. Median procedure time (groin to recanalization) was 35 minutes (8-161 minutes). During the procedure, distal emboli in previously unaffected territories were found in 5 (6%) patients. There were 3 vasospasms (4%) and no vessel perforations. Intracranial hemorrhage on CT at day 1 was found in 18 17 (2321%) patients, none with subarachnoid hemorrhages, and 5 were symptomatic (6%). Good clinical outcome occurred in 4749/68 78 patients (6963%). CONCLUSIONS: In this multicenter retrospective study, the EmboTrap device achieved high recanalization rates, good clinical outcomes and was safe in treating acute stroke patients with large vessel occlusions.

AB - Magnetic Fe3O4 nanoparticles were prepared and embedded into the Combi-CLEAs to produce the magnetic Combi-CLEAs in this work. The process for magnetic Combi CLEAs preparation was optimized, and its properties were investigated. The optimum temperature, thermal stability and optimum pH of magnetic Combi-CLEAs were similar to those of Combi-CLEAs. The catalytic performance of magnetic Combi CLEAs was tested with the biosynthesis of (S)-ethyl 4-chloro-3-hydroxybutyrate ((S)-CHBE). Magnetic Combi-CLEAs could tolerate higher substrate concentration in the biphasic system. The catalytic efficiency and long-term operational stability of magnetic Combi-CLEAs were obviously superior to those of Combi-CLEAs in both aqueous and biphasic systems. Embedding of magnetic Fe3O4 nanoparticles endowing rigidity contributed to these improvements. Furthermore, the preparation of magnetic Combi-CLEAs was easy, and its recovery during multiple batches of reactions could be fulfilled by magnetic field. Aforementioned advantages make the magnetic Combi-CLEAs hold obvious potential for industrial application. PMID- 29452131 TI - Synergism between a cell penetrating peptide and a pH-sensitive cationic lipid in efficient gene delivery based on double-coated nanoparticles. AB - We report on the development of a highly efficient gene delivery system based on synergism between octaarginine (R8), a representative cell penetrating peptide, and YSK05, a recently developed pH-sensitive cationic lipid. Attaching a high density of R8 on the surface of YSK05 nanoparticles (NPs) that contained encapsulated plasmid DNA resulted in the formation of positively charged NPs with improved transfection efficiency. To avoid the development of a net positive charge, we controlled the density and topology of the R8 peptide through the use of a two-step coating methodology, in which the inner lipid coat was modified with a low density of R8 which was then covered with an outer neutral YSK05 lipid layer. Although used in low amounts, the R8 peptide improved cellular uptake and endosomal escape of the DNA encapsulated in YSK05 NPs, which resulted in a high transfection efficiency. The two-step coating design was essential for achieving a high degree of transfection, as evidenced by the low activity of NPs modified with the same amount of R8 in a regular single-coated design. In addition, a high transfection efficiency was not observed when R8 or YSK05 were used alone, which confirms the existence of a synergistic effect between both components. The results of this study indicate that cationic cell penetrating peptides have the ability to improve transfection activities without imparting a net positive charge when used in the proper amount and in conjunction with the appropriate design. This is expected to significantly increase the potential applications of these peptides as tools for augmenting the activity of lipid nanoparticles used in gene delivery. PMID- 29452132 TI - Effect of the GSTM1 gene deletion on glycemic variability, sympatho-vagal balance and arterial stiffness in patients with metabolic syndrome, but without diabetes. AB - AIMS: An increased rate of cerebrovascular complications in patients with metabolic syndrome (MetS) has been reported. Previous studies demonstrated an association between glycemic variability (GV) and cerebrovascular reactivity (CRV) in MetS, thus suggesting a putative role of GV on cerebrovascular events. Although the pathophysiological mechanism linking GV to damage is still to be elucidated, evidence suggests oxidative stress plays a crucial role. Since functional variants in glutathione S-transferases (GST) genes modulate the cellular detoxification processes, the aim of this study was to elucidate the involvement of GSTs in MetS and investigating the correlation with GV, arterial stiffness, and sympatho-vagal (SV) balance. METHODS: A hundred metabolic syndrome patients without diabetes underwent GST gene polymorphism analysis and a sub sample 36 patients were randomly selected to investigate the correlation between GST gene polymorphisms and GV, and sympatho-vagal (SV) balance and arterial stiffness. RESULTS: GSTM1 showed a significant association with several GV, arterial stiffness, and SV balance indexes. In particular, the GSTM1 deletion positively correlates with lower values of these indexes when compared to the presence of the gene. CONCLUSIONS: Therefore, we suggested a global influence of GSTM1 deletion on the GV, arterial stiffness, and SV balance pathways in MetS patients, probably also interacting with AMP-activated protein kinase (AMPK) regulation. Our novel findings indicate GSTM1 could be a risk locus in MetS development and shed light novel scenarios on the role of glucose fluctuations in neurological impairments. PMID- 29452133 TI - Some properties of the conditioned reconstructed process with Bernoulli sampling. AB - In many areas of genetics it is of relevance to consider a population of individuals that is founded by a single individual in the past. One model for such a scenario is the conditioned reconstructed process with Bernoulli sampling that describes the evolution of a population of individuals that originates from a single individual. Several aspects of this reconstructed process are studied, in particular the Markov structure of the process. It is shown that at any given time in the past, the conditioned reconstructed process behaves as the original conditioned reconstructed process after a suitable time-dependent change of the sampling probability. Additionally, it is discussed how mutations accumulate in a sample of particles. It is shown that random sampling of particles at the present time has the effect of making the mutation rate look time-dependent. Conditions are given under which this sampling effect is negligible. A possible extension of the reconstructed process that allows for multiple founding particles is discussed. PMID- 29452134 TI - Effect of High Intensity Interval Training on Cardiac Function in Children with Obesity: A Randomised Controlled Trial. AB - BACKGROUND: High intensity interval training (HIIT) confers superior cardiovascular health benefits to moderate intensity continuous training (MICT) in adults and may be efficacious for improving diminished cardiac function in obese children. The aim of this study was to compare the effects of HIIT, MICT and nutrition advice interventions on resting left ventricular (LV) peak systolic tissue velocity (S') in obese children. METHODS: Ninety-nine obese children were randomised into one of three 12-week interventions, 1) HIIT [n = 33, 4 * 4 min bouts at 85-95% maximum heart rate (HRmax), 3 times/week] and nutrition advice, 2) MICT [n = 32, 44 min at 60-70% HRmax, 3 times/week] and nutrition advice, and 3) nutrition advice only (nutrition) [n = 34]. RESULTS: Twelve weeks of HIIT and MICT were equally efficacious, but superior to nutrition, for normalising resting LV S' in children with obesity (estimated mean difference 1.0 cm/s, 95% confidence interval 0.5 to 1.6 cm/s, P < 0.001; estimated mean difference 0.7 cm/s, 95% confidence interval 0.2 to 1.3 cm/s, P = 0.010, respectively). CONCLUSIONS: Twelve weeks of HIIT and MICT were superior to nutrition advice only for improving resting LV systolic function in obese children. PMID- 29452135 TI - Evidence-Based Exercise Recommendations to Reduce Hepatic Fat Content in Youth- a Systematic Review and Meta-Analysis. AB - The main purposes of this study were to elucidate the effects of supervised exercise training (ET) interventions on hepatic fat content and on non-alcoholic fatty liver disease (NAFLD) prevalence in children and adolescents and to provide information about the optimal ET prescription (type, intensity, volume, and frequency) needed to reduce hepatic fat content in youths. Supervised-ET interventions performed in children and adolescents (6-19 years) that provided results of exercise effects on hepatic fat content or NAFLD prevalence were included. Supervised-exercise significantly reduced hepatic fat content compared to the control groups. Lifestyle interventions that included supervised-ET significantly reduced the prevalence of NAFLD. This systematic review and meta analysis shows that supervised-ET could be an effective strategy in the management and prevention of NAFLD in children and adolescents. Both aerobic and resistance ET, at vigorous or moderate-to-vigorous intensities, with a volume >=60 min/session and a frequency >=3 sessions/week, aiming to improve cardiorespiratory fitness and muscular strength, had benefits on hepatic fat content reduction in youth. These data concur with the international recommendations of physical activity for health promotion in youth and may be useful when designing ET programs to improve and prevent hepatic steatosis in the pediatric population. PMID- 29452136 TI - Neuroprotective effects of valproic acid on brain ischemia are related to its HDAC and GSK3 inhibitions. AB - Valproic acid (VA) is an antiepileptic that is also used for the treatment of bipolar disorders. The objective was to evaluate the neuroprotective effects of VA on a brain ischemia model. The groups of male Wistar rats were: SO (sham operated), ischemic and ischemic treated with VA (25, 50 and 100 mg/kg, p.o.). After anesthesia with ketamine and xilazine, the animals were subjected to clamping of carotid arteries (30 min) and reperfusion. Except for the carotid clamping, the SO group was submitted to the same procedure. On the 7th day, the animals were behaviorally evaluated, euthanized and had their brain dissected for neurochemical and immunohistochemical assays. The data were analyzed by ANOVA and Tukey as the post hoc test. The results showed that VA reversed partly or completely the behavioral (locomotor activity and memory deficits), neurochemical (striatal DA and DOPAC levels, brain nitrite and lipid peroxidation) and immunohistochemical alterations (iNOS, COX-2, HDAC and GSK3) observed in the untreated ischemic group. VA neuroprotective effects are probably related to its anti-inflammatory and antioxidant properties, as well as to HDAC and GSK3 inhibitory effects. These findings stimulate translational studies focusing on VA as a neuroprotective drug to be potentially used in the clinic for several neurological conditions. PMID- 29452138 TI - Exposure to low level of lead during preweaning period increases metallothionein 3 expression and dysregulates divalent cation levels in the brain of young rats. AB - Lead (Pb) is a neurotoxic heavy metal, but the mechanism of its neurotoxicity is not clearly understood. Expression of metallothioneins (MTs) is induced in response to heavy metal exposure as a protective mechanism against heavy metal toxicity. There are several isoforms of MTs (MT-1 to 4), of which MT-3 is the neuron specific isoform, which also has neurite growth inhibitory effects. Whereas, the induction of MT-1 and 2 in response to Pb has been reported, the effect of Pb on the expression of MT-3 in the brain has not been documented. This study aimed at investigating the effect of Pb exposure on the expression of MT-3 in the cerebrum and hippocampus. Wistar rat pups were exposed to Pb via their dams' drinking water (0.2% lead acetate in deionized water) from postnatal day (PND) 0 to 21 and directly via drinking water until PND30. Expression of MT-3 was measured by Western blot and quantitative RT-PCR. MT-3 localization was done by immunohistochemistry. Divalent metal ions were analysed by atomic absorption spectrophotometry. Levels of Pb in blood and cerebrum were significantly increased, while that of copper (Cu), zinc (Zn) and manganese (Mn) were significantly decreased in the Pb-exposed rats at both PND21 and PND30. MT-3 protein was significantly increased in the cerebrum (by 2.5-fold) and in hippocampus (1.4 to 3.2-fold) in both PND21 and PND30 Pb-exposed rats over controls. MT-3 gene expression also increased in the cerebrum (by 42%), and in the hippocampus (by 65% and 43% in the PND21 and PND30 rats, respectively), in the Pb-exposed rats over controls, but the increase was statistically significant (p < 0.05) only in the PND30 rats. Pb exposure significantly increased (p < 0.05) percentage of MT-3 immunoreactive cells in Cornu Ammonis and dentate gyrus regions in the PND21 rats, and in the Cornu Ammonis 1, dentate gyrus and cortex regions in the PND30 rats. Our data thus provide convincing evidence that exposure to low levels of Pb during preweaning period increases the expression of MT-3 in the brain of rats. PMID- 29452137 TI - Aryl hydrocarbon receptor (AhR) mediated short-term effects of 2,3,7,8 tetrachlorodibenzo-p-dioxin (TCDD) on bile acid homeostasis in mice. AB - The effects of the most potent aryl hydrocarbon receptor (AhR) agonist 2,3,7,8 tetrachlorodibenzo-p-dioxin (TCDD) on bile acid (BA) homeostasis was examined in male and female wild-type and AhR-null mice shortly after 4-day exposure, rather than at a later time when secondary non-AhR dependent effects are more likely to occur. TCDD had similar effects on BA homeostasis in male and female mice. TCDD decreased the concentration of total-(Sigma) BAs in liver by approximately 50% (all major BA categories except for the non-6,12-OH BAs), without decreasing the expression of the rate limiting BA synthetic enzyme (Cyp7a1) or altering the major BA regulatory pathways (FXR) in liver and intestine. Even though the Sigma BAs in liver were markedly decreased, the Sigma-BAs excreted into bile were not altered. TCDD decreased the relative amount of 12-OH BAs (TCA, TDCA, CA, DCA) in bile and increased the biliary excretion of TCDCA and its metabolites (TalphaMCA, TUDCA); this was likely due to the decreased Cyp8b1 (12alpha-hydroxylase) in liver. The concentration of Sigma-BAs in serum was not altered by TCDD, indicating that serum BAs do not reflect BA status in liver. However, proportions of individual BAs in serum reflected the decreased expression of Cyp8b1. All these TCDD-induced changes in BA homeostasis were absent in AhR-null mice. In summary, through the AhR, TCDD markedly decreases BA concentrations in liver and reduces the 12alpha-hydroxylation of BAs without altering Cyp7a1 and FXR signaling. The TCDD-induced decrease in Sigma-BAs in liver did not result in a decrease in biliary excretion or serum concentrations of Sigma-BAs. PMID- 29452139 TI - Reply by the Authors.

AB - ETHNOPHARMACOLOGICAL IMPORTANCE: Catharanthus roseus (L.) G. Don. is an important medicinal plant with rich sources of remarkable health benefits consisting more than 100 alkaloids and significant amounts of bioactive compounds, which have been widely used as a folk medicine for treatment of several pathologies. THE AIM OF THE STUDY: In the present study, we isolated and cultured innately undifferentiated cambium meristematic cells (CMCs), which were observed stable cell growth, enhancement of bioactive compounds from C.roseus. MATERIALS AND METHODS: We attempted to determine the effect of association between time-course growth rates, bioactive compounds and terpenoids indole alkaloid (TIA) contents as well as antioxidant and anticancer efficacies of C. roseus CMC suspension culture treated by UV-C. RESULTS: The bioactive compounds, vincristine contents, and antioxidant power were noticed significantly higher in 60 min exposure at 5 cm distances and with the directly collected sample (T7). A similar trend has also been noticed from the anticancer activity. Demonstration of TIA accumulation was found higher at 5 min exposure, at 20 cm distances and 48 h of incubation (T21) and the result of TIA contents had the highest correlation effects of anticancer activities. CONCLUSION: In the current study, we demonstrated that UV C light could enhance the production of the essential compounds and bioactivities in the CMCs of C. roseus, and thus, C. roseus CMCs have the potential to serve as an industrial platform for the production of bioactive alkaloids and antioxidant, anticancer activity. Moreover, additional efforts should be made to irradiate CMC suspension cultures from C. roseus with UV-C to achieve better pharmacological profiles. PMID- 29452142 TI - In Vitro-In Vivo Evaluation of an Oral Ghost Drug Delivery Device for the Delivery of Salmon Calcitonin. AB - An orally administered site-specific Oral Ghost Drug Delivery (OGDD) device was developed and evaluated for the administration of salmon calcitonin. In vitro drug release studies have been undertaken using biorelevant media and aspirated gastrointestinal fluid from a large white pig in addition to characterization of a formulated trimethyl chitosan blend formulated and prepared into a loaded mini pellet system. In vivo drug release analysis in a large white pig model has further been undertaken on the OGDD device and a commercial intramuscular injection to ascertain the release properties of the OGDD device in an animal model in comparison with the currently used treatment option for the administration of salmon calcitonin. Results of this study have detailed the success of the prepared system during both in vitro and in vivo analyses with the OGDD providing a greater control of release of salmon calcitonin when compared to the commercial product.

AB - Sexually transmitted Chlamydia trachomatis infects more than 100 million people annually, and untreated chlamydia infections can cause severe complications. Therefore, there is an urgent need for a chlamydia vaccine. The Ctrachomatis major outer membrane protein (MOMP) is highly immunogenic but is a challenging vaccine candidate by being an integral membrane protein, and the immunogenicity depends on a correctly folded structure. We investigated the biophysical properties of the recombinant MOMP-based fusion antigen CTH522, which is tested in early human clinical trials. It consists of a truncated and cysteine-free version of MOMP fused to 4 variable domains from serovars D-G. In the native state, CTH522 did not exist as a monomer but showed an unusual self-assembly into nanoparticles with a negative zeta potential. In contrast to the beta-barrel structure of MOMP, native CTH522 contained no well-defined secondary structural elements, and no thermal transitions were measurable. Chemical unfolding resulted in monomers that upon removal of the denaturant self-assembled into higher order structures, comparable to the structure of the native protein. The conformation of CTH522 in nanoparticles is thus not entirely random and contains structural elements stabilized via denaturant-disruptable hydrophobic interactions. In conclusion, CTH522 has an unusual quaternary structure of supramolecular self assemblies. PMID- 29452144 TI - Recent progress in immune-metabolism.

PMID- 29452146 TI - The Hippo/YAP1 pathway interacts with FGFR1 signaling to maintain stemness in lung cancer. AB - The Hippo pathway plays a critical role in organ size control, tissue homeostasis and tumor genesis through its key transcription regulator Yes-associated protein1 (YAP1), but the mechanism underlying its role in lung cancer is unclear. We hypothesized that YAP1 influences FGFR1 signaling to maintain cancer stem-like cell (CSC) properties in FGFR1-amplified lung cancer. In support of this, our data confirms that expression levels of YAP1 are positively associated with those of FGFR1 in clinical lung carcinoma samples as measured by real-time PCR, western blot, and immunohistochemistry (IHC) staining. Mechanistically, YAP1 up-regulates FGFR1 expression at the level of promoter through the TEAD binding site while bFGF/FGFR1 induces YAP1 expression via large tumor suppressors 1(LATS1). In addition, the absence of YAP1 abolishes self-renewal ability in lung cancer. Furthermore, an orthotropic mouse model highlights the function of YAP1 in the initiation and metastasis of lung cancer. Verteporfin, a YAP1 inhibitor, effectively inhibits both YAP1 and FGFR1 expression in lung cancer. Thus, we conclude that YAP1 is a potential therapeutic target for lung cancer. Combined targeting of YAP1 and FGFR1 may provide benefits to patients with FGFR1-amplified lung cancer. PMID- 29452147 TI - Combination of Kras activation and PTEN deletion contributes to murine hepatopancreatic ductal malignancy. AB - Kras mutations are among the most common genetic abnormalities in human neoplasms, including cholangiocarcinomas, pancreatic cancer and colon cancer. PTEN has previously been associated with cholangiocarcinoma development in murine models. Here, we have established novel mouse models of neoplasms by liver specific and biliary-pancreatic Kras activation and PTEN deletion. By liver specific disruption of PTEN and activation of Kras in mice caused rapid development of intrahepatic biliary epithelial proliferative lesions (Intrahepatic cholangiocarcinoma, ICC), which progress through dysplasia to invasive carcinoma. In contrast, Kras activation in combination with heterozygous PTEN deletion induced mixed carcinomas of liver (both ICC and hepatocellular carcinoma, HCC), whereas Kras activation alone did not induce biliary tract neoplasm. Use of Sox9-Cre-LoxP-based approach to coordinately delete PTEN and activate Kras in the adult mouse resulted in not only development of low-grade biliary lesions (ICC and extrahepatic bile duct carcinoma, ECC) but also pancreatic carcinomas. Our data provide a functional link between PTEN gene status, hepatobiliary cell fate, and HCC, biliary carcinoma, pancreatic cancer pathogenesis, and present novel genetically engineered mouse models of PTEN loss driven malignancy. PMID- 29452148 TI - Complete inhibition of fetal movement in the day 40 pregnant goat model by the piperidine alkaloid anabasine but not related alkaloids. AB - Four chemically similar alkaloids, anabasine, anabaseine, epibatidine and dimethylphenylpiperazinium (DMPP), are potent nicotinic acetylcholine receptor agonists of fetal muscle nicotinic acetylcholine receptors in human TE-671 cells. Based on results with these cells, we hypothesized that the alkaloids would completely inhibit ultrasound-monitored fetal movement in a goat model. Different, single doses of anabasine, anabaseine, epibatidine, DMPP, or saline control were administered I.V. to pregnant goats on day 40 of gestation and the number of fetal movements per 5 min sample was measured by ultrasound at times 0, 0.5, 1, 2, 4 and 8 h. The differences among does in fetal movements were more consistent at dosing and following recovery for doses of anabasine above 0.125 mg/kg compared to the other compounds and dosages. Anabasine actions were dose dependent with an IC50 value of ~0.1 mg/kg, and, at a dose of 0.8 mg/kg, completely inhibited fetal movement for 1.5 h after dosing. Anabaseine, epibatidine, and DMPP failed to completely inhibit fetal movement in day 40 pregnant goats at doses predicted to be effective. These results suggest that while experiments with TE-671 cells provide valuable information and predictions of the actions of plant alkaloids on fetal movement, in vivo experiments are still required in order to determine the ability of an alkaloid to inhibit fetal movement in livestock species. Moreover, other pharmacological properties such as receptor differences between mammalian species and differences in the pharmacokinetic properties of the alkaloids also are likely to weaken teratologic predictions based solely on the in vitro data. PMID- 29452149 TI - Facial gender but not emotion distinguishes neural responses of 10- to 13-year old children with social anxiety disorder from healthy and clinical controls. AB - OBJECTIVE: The current study examined neural and behavioral responses to angry, happy and neutral faces in childhood social anxiety disorder (SAD). METHOD: Behavioral (reaction time and accuracy) and electrocortical measures (P100, N170, EPN, LPP) were assessed during a facial emotion identification task in children (age 10-13) with SAD (n = 32), clinical controls with mixed anxiety disorders (n = 30), and healthy controls (n = 33). RESULTS: Overall, there were no group differences in behavioral or neural responses to emotional faces. However, children with SAD showed an attenuated LPP to male relative to female faces, while the opposite pattern emerged in the other two groups. DISCUSSION: Stimulus gender, but not facial emotion drove group-specific effects, which became evident in later, more elaborate stages of attention processing. The present study provides preliminary indications of gender effects in childhood SAD which should be further investigated by future studies. PMID- 29452150 TI - Cerebral blood flow velocity and autoregulation in paediatric patients following a global hypoxic-ischaemic insult. AB - AIM: To describe the cerebral blood flow velocity pattern and investigate cerebral autoregulation using transcranial Doppler ultrasonography (TCD) following a global hypoxic-ischaemic (HI) event in children. METHODS: This was a prospective, observational study in a quaternary-level paediatric intensive care unit. Intubated children, newborn to 17 years admitted to the PICU following HI injury (asphyxia, drowning, cardiac arrest) were eligible for inclusion. TCD was performed daily until post-injury day 8, discharge, or death, whichever occurred earliest. RESULTS: Twenty-six patients were enrolled. Median age was 3 years (0.33, 11.75), initial pH 6.95, and initial lactate 5.4. Median post resuscitation Glasgow Coma Score was 3T. Across the entire cohort, cerebral blood flow velocity (CBFV) was near normal on day 1. Flow velocity increased to a maximum median value of 1.4 standard deviations above normal on day 3 and slowly downtrended back to baseline by the end of the study period. Median Paediatric Extended Version of the Glasgow Outcome Score was 4 at three months. No patient in the favourable outcome group had extreme CBFV on day one, and only one patient in the favourable group had extreme CBFV on PID 2. In contrast, 38% of patients in the unfavourable group had extreme CBFV on PID 1 (p=.039 compared to frequency in favourable group), and 55% had extreme CBFV on PID 2 (p = .023 compared to frequency in favourable group). No patient had consistently intact cerebral autoregulation throughout the study period. CONCLUSIONS: Following a HI event, patients with favourable neurologic outcomes had flow velocity near normal whereas unfavourable outcomes had more extreme flow velocity. Intermittently intact cerebral autoregulation was more frequently seen in those with favourable neurologic outcomes though return to the autoregulatory baseline appears delayed. PMID- 29452151 TI - Does reduced mastication influence cognitive and systemic health during aging? AB - There is a growing body of literature which suggests that oral health and mastication can influence cognitive and systemic health during aging. However, it is currently unclear whether oral health, masticatory efficiency, cognitive health and systemic health merely deteriorate independently with age, or whether mechanisms exist linking mastication to cognitive and systemic health directly. The aim of this paper is to review the extent to which reduced mastication influences cognitive and systemic health during aging because this knowledge may underpin future interventions that improve quality of life. Current evidence suggests that a deterioration in mastication and oral health during aging can have: 1) direct effects on systemic health through mechanisms such as the migration of the oral microbiota into the systemic environment, and 2) indirect effects on systemic health through changes nutrient intake. A loss of teeth and reduction in masticatory efficiency during aging can have: 1) direct effects on cognitive performance and potentially impact cognitive health through mechanisms such as enhanced adult hippocampal neurogenesis, and 2) indirect effects on cognitive health through changes in nutrient intake. It is concluded that oral health and masticatory efficiency are modifiable factors which influence the risk poor cognitive and systemic health during aging, although it is currently premature to propose chewing-based interventions to slow the rate of cognitive decline and improve cognitive health during aging. Future research should include large-scale longitudinal studies which control for the types of confounding factors which concurrently influence the association between mastication and cognitive and systemic health. PMID- 29452152 TI - Behavioral and endocrine consequences of placentophagia in male California mice (Peromyscus californicus). AB - Ingestion of placenta by mammalian mothers can lead to changes in pain sensitivity, hormone levels, and behavioral responses to newborns. In some biparental mammals, males, in addition to females, ingest placenta when their offspring are born. In the monogamous, biparental California mouse (Peromyscus californicus), males first become attracted to placenta when cohabitating with their pregnant mate, and virgin males administered placenta are less neophobic than males given oil vehicle. In this study, we investigated the effects of placentophagia on pain sensitivity, anxiety-like behavior, behavioral responses to pups, and circulating corticosterone levels of both breeding and nonbreeding male California mice. We orally administered either a conspecific placenta or oil vehicle to male mice from three reproductive conditions (first-time fathers, first-time expectant fathers, and virgin males) and tested their pain sensitivity 1 h later, as well as their exploratory behavior and paternal responsiveness in an open field 4 h post-treatment. We measured plasma corticosterone immediately after the open-field test. We found that placenta-treated males, independent of reproductive condition, traveled significantly longer distances in the open field than males treated with oil, indicative of lower anxiety. Additionally, fathers had shorter latencies to approach and to care for pups (i.e., huddling and licking pups), and spent more time engaging in these behaviors, than did age matched expectant fathers and virgin males, independent of treatment. We found no effect on plasma corticosterone levels or pain sensitivity as a result of either treatment or reproductive condition. These findings indicate that placenta ingestion decreases anxiety-related behaviors in male California mice, but might not influence pain sensitivity, paternal responsiveness, or plasma corticosterone concentrations. PMID- 29452154 TI - Study of petrolatum structure: Explaining its variable rheological behavior. AB - The rheological properties of petrolatum are dependent on both temperature and thermal history. How this thermal dependency can be explained is unclear. In the past it has been suggested that the structure of petrolatum consists of a three dimensional crystalline network. This has been established using old microscopic techniques only. Therefore a study on the microstructure of petrolatum was conducted using rheometry, DSC, pulsed NMR, polarized light microscopy and synchrotron X-ray. The combination of these techniques show that petrolatum is composed of 21% solid material at room temperature. This consists of partly crystalline lamellar sheets which are packed in stacks. The occurrence of these lamellar sheets is temperature dependent and the number of lamellar stacks is dependent on thermal history. It was shown that rheological differences in petrolatum can be explained by the number of lamellar stacks present, where more lamellar stacks result in more rigid petrolatum.

AB - The purpose of this work was to develop a d-alpha-tocopherol polyethylene glycol 1000 succinate (TPGS) decorated nanodiamond (ND) system loading water-insoluble curcumin (ND/CUR/TPGS) to improve the colloidal dispersity and oral bioavailability of the preparation. CUR was physically loaded into ND clusters, then TPGS was coated to the ND/CUR complex forming amorphous nanostructure on the interparticle nanocage of the ND substrate. The formulation of the nanocomplexes was optimized using response surface methodology, and the optimal ND/CUR/TPGS showed small particle size (196.32 nm), high drug loading efficiency (81.59%) and core-shell structure. In vitro release study demonstrated that the nanocomplexes provided a sustained release behavior. The absorptive concentration of ND/CUR/TPGS was dramatically improved in total intestinal tract compared with CUR suspension, and the absorption was controlled by multiple transcytosis mechanisms. Furthermore, the pharmacokinetic studies demonstrated that ND/CUR/TPGS had significantly higher Cmax (4.50-fold), larger AUC0-t (10.67 fold), and longer MRT0-t (3.07-fold) in contrast with that of CUR suspension. Therefore, ND/CUR/TPGS presented great potential for oral delivery of insoluble and poorly permeable drugs. PMID- 29452155 TI - Comparative developmental biology of the cardiac inflow tract. AB - The vertebrate heart receives the blood through the cardiac inflow tract. This area has experienced profound changes along the evolution of vertebrates; changes that have a reflection in the cardiac ontogeny. The development of the inflow tract involves dynamic changes due to the progressive addition of tissue derived from the secondary heart field. The inflow tract is the site where oxygenated blood coming from lungs is received separately from the systemic return, where the cardiac pacemaker is established and where the proepicardium develops. Differential cell migration towards the inflow tract breaks the symmetry of the primary heart tube and determines the direction of the cardiac looping. In air breathing vertebrates, an inflow tract reorganization is essential to keep separate blood flows from systemic and pulmonary returns. Finally, the sinus venosus endocardium has recently been recognized as playing a role in the constitution of the coronary vasculature. Due to this developmental complexity, congenital anomalies of the inflow tract can cause severe cardiac diseases. We aimed to review the recent literature on the cellular and molecular mechanisms that regulate the morphogenesis of the cardiac inflow tract, together with comparative and evolutionary details, thus providing a basis for a better understanding of these mechanisms. PMID- 29452156 TI - Establishment of a PRKAG2 cardiac syndrome disease model and mechanism study using human induced pluripotent stem cells. AB - PRKAG2 cardiac syndrome is a distinct form of human cardiomyopathy characterized by cardiac hypertrophy, ventricular pre-excitation and progressive cardiac conduction disorder. However, it remains unclear how mutations in the PRKAG2 gene give rise to such a complicated disease. To investigate the underlying molecular mechanisms, we generated disease-specific hiPSC-derived cardiomyocytes from two brothers both carrying a heterozygous missense mutation c.905G>A (R302Q) in the PRKAG2 gene and further corrected the R302Q mutation with CRISPR-Cas9 mediated genome editing. Disease-specific hiPSC-cardiomyocytes recapitulated many phenotypes of PRKAG2 cardiac syndrome including cellular enlargement, electrophysiological irregularities and glycogen storage. In addition, we found that the PRKAG2-R302Q mutation led to increased AMPK activities, resulting in extensive glycogen deposition and cardiomyocyte hypertrophy. Finally we confirmed that disrupted phenotypes of PRKAG2 cardiac syndrome caused by the specific PRKAG2-R302Q mutation can be alleviated by small molecules inhibiting AMPK activity and be rescued with CRISPR-Cas9 mediated genome correction. Our results showed that disease-specific hiPSC-CMs and genetically-corrected hiPSC cardiomyocytes would be a very useful platform for understanding the pathogenesis of, and testing autologous cell-based therapies for, PRKAG2 cardiac syndrome. PMID- 29452157 TI - Hypertrophic cardiomyopathy mutation R58Q in the myosin regulatory light chain perturbs thick filament-based regulation in cardiac muscle. AB - Hypertrophic cardiomyopathy (HCM) is frequently linked to mutations in the protein components of the myosin-containing thick filaments leading to contractile dysfunction and ultimately heart failure. However, the molecular structure-function relationships that underlie these pathological effects remain largely obscure. Here we chose an example mutation (R58Q) in the myosin regulatory light chain (RLC) that is associated with a severe HCM phenotype and combined the results from a wide range of in vitro and in situ structural and functional studies on isolated protein components, myofibrils and ventricular trabeculae to create an extensive map of structure-function relationships. The results can be understood in terms of a unifying hypothesis that illuminates both the effects of the mutation and physiological signaling pathways. R58Q promotes an OFF state of the thick filaments that reduces the number of myosin head domains that are available for actin interaction and ATP utilization. Moreover this mutation uncouples two aspects of length-dependent activation (LDA), the cellular basis of the Frank-Starling relation that couples cardiac output to venous return; R58Q reduces maximum calcium-activated force with no significant effect on myofilament calcium sensitivity. Finally, phosphorylation of R58Q-RLC to levels that may be relevant both physiologically and pathologically restores the regulatory state of the thick filament and the effect of sarcomere length on maximum calcium-activated force and thick filament structure, as well as increasing calcium sensitivity. We conclude that perturbation of thick filament based regulation may be a common mechanism in the etiology of missense mutation associated HCM, and that this signaling pathway offers a promising target for the development of novel therapeutics. PMID- 29452158 TI - Protein kinase C epsilon mediates the inhibition of angiotensin II on the slowly activating delayed-rectifier potassium current through channel phosphorylation. AB - The slowly activating delayed rectifier K+ current (IKs) is one of the main repolarizing currents in the human heart. Evidence has shown that angiotensin II (Ang II) regulates IKs through the protein kinase C (PKC) pathway, but the related results are controversial. This study was designed to identify PKC isoenzymes involved in the regulation of IKs by Ang II and the underlying molecular mechanism. The whole-cell patch-clamp technique was used to record IKs in isolated guinea pig ventricular cardiomyocytes and in human embryonic kidney (HEK) 293 cells co-transfected with human KCNQ1/KCNE1 genes and Ang II type 1 receptor genes. Ang II inhibited IKs in a concentration-dependent manner in native cardiomyocytes. A broad PKC inhibitor Go6983 (not inhibiting PKCepsilon) and a selective cPKC inhibitor Go6976 did not affect the inhibitory action of Ang II. In contrast, the inhibition was significantly attenuated by PKCepsilon selective peptide inhibitor epsilonV1-2. However, direct activation of PKC by phorbol 12-myristate 13-acetate (PMA) increased the cloned human IKs in HEK293 cells. Similarly, the cPKC peptide activator significantly enhanced the current. In contrast, the PKCepsilon peptide activator inhibited the current. Further evidence showed that PKCepsilon knockdown by siRNA antagonized the Ang II-induced inhibition on KCNQ1/KCNE1 current, whereas knockdown of cPKCs (PKCalpha and PKCbeta) attenuated the potentiation of the current by PMA. Moreover, deletion of four putative phosphorylation sites in the C-terminus of KCNQ1 abolished the action of PMA. Mutation of two putative phosphorylation sites in the N-terminus of KCNQ1 and one site in KCNE1 (S102) blocked the inhibition of Ang II. Our results demonstrate that PKCepsilon isoenzyme mediates the inhibitory action of Ang II on IKs and by phosphorylating distinct sites in KCNQ1/KCNE1, cPKC and PKCepsilon isoenzymes produce the contrary regulatory effects on the channel. These findings have provided new insight into the molecular mechanism underlying the modulation of the KCNQ1/KCNE1 channel. PMID- 29452160 TI - Orchiectomy and letrozole differentially regulate synaptic plasticity and spatial memory in a manner that is mediated by SRC-1 in the hippocampus of male mice. AB - Hippocampal synaptic plasticity is the basis of spatial memory and cognition and is strongly regulated by both testicular androgens (testosterone, T) and hippocampal estrogens (17beta-estradiol, E2) converted from T by aromatase, which is inhibited by letrozole (LET), but the contribution of each pathway to spatial memory and the associated mechanisms are unclear. In this study, we first used orchiectomy (ORX) and LET injection to investigate the effects of T and hippocampal E2 on spatial memory and hippocampal synaptic plasticity. Next, we examined the changes in steroid receptors and steroid receptor coactivator-1 (SRC 1) under these treatments. Finally, we constructed an SRC-1 RNA interference lentivirus and an AROM overexpression lentivirus to explore the roles of SRC-1 under T replacement and AROM overexpression. The results revealed spatial memory impairment only after LET. LET induced more actin depolymerization and greater losses of spines, synapses, and postsynaptic proteins compared with ORX. Moreover, although ERalpha and ERbeta were affected by LET and ORX at similar levels, AR, GPR30, and SRC-1 were dramatically decreased by LET compared with ORX. Finally, the T and AROM overexpression-induced changes in synaptic proteins and actin polymerization were blocked by SRC-1 inhibition. These results demonstrate that testicular androgens play a limited role, whereas local E2 is more important for cognition, which may explain why castrated men such as eunuchs usually do not have cognitive disorders. These results also suggest a pivotal role of SRC-1 in the action of steroids; thus, SRC-1 may serve as a novel therapeutic target for cognitive disorders. PMID- 29452159 TI - CYP27A1 acts on the pre-vitamin D3 photoproduct, lumisterol, producing biologically active hydroxy-metabolites. AB - Prolonged exposure of the skin to UV radiation causes previtamin D3, the initial photoproduct formed by opening of the B ring of 7-dehydrocholesterol, to undergo a second photochemical reaction where the B-ring is reformed giving lumisterol3 (L3), a stereoisomer of 7-dehydrocholesterol. L3 was believed to be an inactive photoproduct of excessive UV radiation whose formation prevents excessive vitamin D production. Recently, we reported that L3 is present in serum and that CYP11A1 can act on L3 producing monohydroxy- and dihydroxy-metabolites which inhibit skin cell proliferation similarly to 1alpha,25-dihydroxyvitamin D3. In this study we tested the ability of human CYP27A1 to hydroxylate L3. L3 was metabolized by purified CYP27A1 to 3 major products identified as 25-hydroxyL3, (25R)-27 hydroxyL3 and (25S)-27-hydroxyL3, by NMR. These three products were also seen when mouse liver mitochondria containing CYP27A1 were incubated with L3. The requirement for CYP27A1 for their formation by mitochondria was confirmed by the inhibition of their synthesis by 5beta-cholestane-3alpha,7alpha,12alpha-triol, an intermediate in bile acid synthesis which serves as an efficient competitive substrate for CYP27A1. CYP27A1 displayed a high kcat for the metabolism of L3 (76 mol product/min/mol CYP27A1) and a catalytic efficiency (kcat/Km) that was 260 fold higher than that for vitamin D3. The CYP27A1-derived hydroxy-derivatives inhibited the proliferation of cultured human melanoma cells and colony formation with IC50 values in the nM range. Thus, L3 is metabolized efficiently by CYP27A1 with hydroxylation at C25 or C27 producing metabolites potent in their ability to inhibit melanoma cell proliferation, supporting that L3 is a prohormone which can be activated by CYP-dependent hydroxylations. PMID- 29452161 TI - C33-A cells transfected with E6*I or E6*II the short forms of HPV-16 E6, displayed opposite effects on cisplatin-induced apoptosis. AB - The HPV-16 E6/E7 bicistronic immature transcript produces 4 mature RNAs: the unspliced HPV-16 E6/E7pre-mRNA product and 3 alternatively spliced mRNAs. The 3 spliced mRNAs encode short forms of the E6 oncoprotein, namely E6*I, E6*II and E6^E7. In this study we showed that transfection of C-33A cells with monocistronic constructs of these cDNAs fused to GFP, produced different effects on apoptosis, after the treatment with cisplatin. Transfection of C-33A cells with the full-length E6-GFP oncoprotein resulted in a 50% decrease in cell death, while the transfection with the E6*I-GFP construct showed only a 25% of diminution of cell death, compared to the control cells. Transfection with the E6^E7-GFP or E7-GFP construct had no effect on the number of the apoptotic cells, compared with control cells. Conversely, transfection with the E6*II construct resulted in higher cell death than the control cells. Taken together, these results suggested that E6*I or E6*II, the short forms of HPV-16 E6, displayed opposite effects on cisplatin-induced apoptosis, when transfected in C-33A cells. PMID- 29452162 TI - Pseudorabies virus induces autophagy to enhance viral replication in mouse neuro 2a cells in vitro. AB - Autophagy of cytoplasmic components plays an essential role in the pathogenic infection process. Furthermore, research suggests that autophagy is an extremely important component of the innate immune response. Our study aimed to reveal the effect of virus-induced autophagy on pseudorabies virus (PRV) replication. Our results confirmed that light chain 3 (LC3)-I was converted into LC3-II after PRV infection; this transition is considered an important indicator of autophagy. Transmission electron microscopy (TEM) revealed that PRV infection could notably increase the number of autophagosomes in mouse neuro-2a (N2a) cells. In addition, LC3-II accumulated in response to chloroquine (CQ) treatment, indicating that PRV infection induced a complete autophagic flux response. Furthermore, our analyses verified differences in the magnitude of autophagy induction by two different PRV isolates, LA and ZJ01. Subsequent analysis showed that the induction of autophagy by rapamycin facilitated PRV replication, while inhibition of autophagy by 3 methyladenine (3-MA) reduced PRV replication. These results indicated that PRV induced autophagy via the classical Beclin-1-Atg7-Atg5 pathway to enhance viral replication in N2a cells in vitro. PMID- 29452163 TI - Screening of binding proteins that interact with Chinese sacbrood virus VP3 capsid protein in Apis cerana larvae cDNA library by the yeast two-hybrid method. AB - Chinese sacbrood virus (CSBV) causes larval death and apiary collapse of Apis cerana. VP3 is a capsid protein of CSBV but its function is poorly understood. To determine the function of VP3 and screen for novel binding proteins that interact with VP3, we conducted yeast two-hybrid screening, glutathione S-transferase pull down, and co-immunoprecipitation assays. Galectin (GAL) is a protein involved in immune regulation and host-pathogen interactions. The yeast two-hybrid screen implicated GAL as a major VP3-binding candidate. The assays showed that the VP3 interacted with GAL. Identification of these cellular targets and clarifying their contributions to the host-pathogen interaction may be useful for the development of novel therapeutic and prevention strategies against CSBV infection. PMID- 29452164 TI - Proposal for a new subtype of the zoonotic genotype 3 Hepatitis E virus: HEV-3l. AB - The near-complete genomic sequences of two hepatitis E virus (HEV) strains, detected from feces of infected pigs, were obtained. Phylogenetic analysis and p distance comparisons of the complete coding regions showed a close relationship to the French swine strain FR-SHEV3c-like detected in 2006 (p-distance value 0.101), belonging to HEV-3 but not assigned to any known subtype. The three HEV sequences showed, relatively high nucleotide distances (p-distance >0.129) compared to the other defined HEV subtype references and unclassified strains. The HEV classification criteria and the high sequence similarity suggest that these strains can be assigned to a putative novel subtype of genotype 3, HEV-3l. PMID- 29452165 TI - The beneficial role of early exercise training following stroke and possible mechanisms. AB - Exercise training is a regular therapy for stroke patients in clinic. However, whether the early exercise is beneficial for stroke patients is still controversial. The review was performed in databases of OVID, PUBMED, and ISI Web of Science, from respective inception to December 2017. In this review, we summarize the effect of different exercise intensity, initiation time, and style on ischemic stroke. Moreover, the possible mechanism is also discussed. The conclusion is that the voluntary exercise is better in promoting the functional recovery following stroke compared to forced exercise; too early initiated exercise might play a harmful role following stroke, while early initiated exercise might exert benefits after stroke; mild and moderate intensity exercise training could generate better neuroprotection in comparison with high intensity exercise training; early excise training could regulate the process of brain edema, cell apoptosis, oxidative damage, stem cells and other mechanisms in order to exert neuroprotection for brain. PMID- 29452166 TI - Metformin ameliorates the progression of atherosclerosis via suppressing macrophage infiltration and inflammatory responses in rabbits. AB - AIMS: The present study aimed to investigate the possible effects of metformin on the progression of atherosclerosis in a rabbit model. MAIN METHODS: Rabbits were randomly divided into three groups (n = 10): the control (Ctrl) group (fed with a chow diet), and two experimental groups, the AS group and the Met group (both received an atherogenic diet). After 2 weeks of acclimatization, the rabbits in the AS and Met groups were given a placebo and metformin, respectively, daily by gavage for 10 weeks. Plasma lipids and inflammatory cytokines were measured. The aorta was isolated for histological and immunohistochemical analysis. In vitro, human umbilical vein endothelial cells (HUVECs) were treated with metformin, and monocyte adhesion and adhesion molecule expression were measured. KEY FINDINGS: Metformin reduced plasma inflammatory cytokine levels but did not alter lipid content. Compared with that in the AS group, the atherosclerosis burden in the Met group was significantly decreased. The lesional macrophage content was reduced, but the lesional collagen content was not affected in the metformin treated rabbits, compared with the corresponding levels in the non-treated controls. Furthermore, the aortic mRNA expression levels of adhesion molecules and inflammatory cytokines in the Met group were also significantly reduced compared with those in the AS group. Metformin treatment reduced monocyte adhesion to endothelial cells (ECs) and adhesion molecule expression, and inhibited rabbit monocyte differentiation into macrophages and the macrophage inflammatory response. SIGNIFICANCE: Our results suggest that metformin impeded the progression of atherosclerosis, possibly by suppressing macrophage infiltration and inflammatory responses. PMID- 29452167 TI - microRNA-136 inhibits proliferation and promotes apoptosis and radiosensitivity of cervical carcinoma through the NF-kappaB pathway by targeting E2F1. AB - AIMS: Several microRNAs (miRs) are expressed aberrantly and associated with progression, tumorigenesis, and prognosis of haematological and solid tumors. The study aimed to identify the effects involved with microRNA-136 (miR-136) on the concurrent enhancement of proliferation, apoptosis and radiosensitivity of cervical carcinoma through the NF-kappaB signaling pathway by targeting E2F1. MAIN METHODS: Totally 338 patients with cervical carcinoma were recruited in this study. The expressions of miR-136, E2F1, p65, CyclinD1, Atm, Chk2, Bcl-2, Survivin and Bax were detected using RT-qPCR and Western blot analysis. Cells with highest miR-136 expression were subsequently assigned into different groups. Cell survival and apoptosis rate were detected by colony formation assay and flow cytometry, respectively. KEY FINDINGS: Compared to the sensitivity group, E2F1, p65, Bcl-2 and Survivin exhibited increased levels, while expression of CyclinD1, Atm, Chk2, Bax and miR-136 was reduced in the confrontation group. Cell survival rate was declined at 6 and 8 Gy of X-ray irradiation compared with 0, 2 and 4 Gy. Compared with the blank and NC groups, expression of E2F1, p65, Bcl-2 and Survivin was increased, while that of CyclinD1, Atm, Chk2, Bax and miR-136 was all decreased. The cell survival rate was increased; while apoptosis rate was decreased in the miR-136 inhibitor group. The trends observed in the miR-136 mimics and siRNA-E2F1 groups were contradictory to the miR-136 inhibitor group. SIGNIFICANCE: Based on our results, miR-136 inhibits proliferation, while acting to promote apoptosis and radiosensitivity in cervical carcinoma by targeting E2F1 through the NF-kappaB signaling pathway, resulting in improved prognoses.

PMID- 29452169 TI - Expression patterns of Toll like receptor (TLR)-2, TLR-4 and myeloid differentiation primary response gene 88 (MYD88) in renal transplant patients developing allograft dysfunction; a cohort study. AB - This cohort intends to determine the sequential dynamic changes in Toll-like receptor (TLR)-4, TLR-2, and myeloid differentiation primary response gene 88 (MYD88) mRNA expressions in PBMCs and biopsy samples from kidney allograft recipients in relation to graft function. This study enrolled 52 renal transplant patients, 27 with well functioning graft (WFG) and 25 graft dysfunction (GD). Peripheral blood samples pre- and post-transplantation (days 2, 90 and 180) were collected to analyze mRNA expression levels of TLR-2, TLR-4, and MYD88 genes in relation to allograft function during one-year follow up. The mean dynamic changes of post-transplant TLR-2, TLR-4, and MYD88 mRNA expressions were significantly higher in GD compared to WFG patients (P = .001). ROC curve analysis based on glomerular filtration rate (GFR) index showed the area under curve (AUC) values for the genes: TLR-2(0.89;P < .001), TLR-4(0.86;P < .001), and MYD88(0.75;P = .003) in the third month post-transplantation for GD diagnosis. The calculated AUCs for the expressions of genes in allograft biopsies were 0.94(TLR-2), 0.95(TLR-4), and 0.98(MYD88) in the sixth month post-transplant based on pathology report (P < .001). Our results indicate that sequential monitoring of the expression patterns of TLR-2, TLR-4, and MYD88 in PBMCs and biopsy samples could be considered as predictive biomarkers for early and late kidney allograft function. PMID- 29452171 TI - Evolution of model specific relative growth rate: Its genesis and performance over Fisher's growth rates. AB - Growth curve models play an instrumental role to quantify the growth of biological processes and have immense practical applications across disciplines. In the modelling approach, the absolute growth rate and relative growth rate (RGR) are two most commonly used measures of growth rates. RGR is empirically estimated by Fisher (1921) assuming exponential growth between two consecutive time points and remains invariant under any choice of the underlying growth model. In this article, we propose a new measure of RGR, called modified RGR, which is sensitive to the choice of underlying growth law. The mathematical form of the growth equations are utilized to develop the formula for model dependent growth rates and can be easily computed for commonly used growth models. We compare the efficiency of Fisher's measure of RGR and modified RGR to infer the true growth profile. To achieve this, we develop a goodness of fit testing procedure using Gompertz model as a test bed. The relative efficiency of the two rate measures is compared by generating power curves of the goodness of fit testing procedure. The asymptotic distributions of the associated test statistics are elaborately studied under Gompertz set up. The simulation experiment shows that the proposed formula has better discriminatory power than the existing one in identifying the true profile. The claim is also verified using existing real data set on fish growth. An algorithm for the model selection mechanism is also proposed based on the modified RGR and is generalized for some commonly used other growth models. The proposed methodology may serve as a valuable tool in growth studies in different research areas. PMID- 29452170 TI - Expression and significance of Sirt1 in renal allografts at the early stage of chronic renal allograft dysfunction. AB - OBJECTIVE: To investigate the expression and significance of Sirt1 in renal allografts at the early stage of chronic renal allograft dysfunction (CRAD). METHODS: CRAD rat models were established using classical orthotopic F344-Lewis kidney transplantation. F344 and Lewis uninephrectomized rats were used as controls. Twelve weeks after the operation, the rats were sacrificed for renal function, histological, immunohistochemistry and molecular biological analyses. RESULTS: The 24-h urinary protein excretion and serum creatinine levels, urine microalbumin/creatinine ratios, and Banff score sums were significantly increased in the CRAD group compared with those in the F344 and Lewis control groups. The degree of mononuclear cell infiltration and interstitial fibrosis (IF) was higher in the CRAD group than in the control groups. Sirt1, TGF-beta1, MCP-1, ICAM-1 expression was up-regulated in CRAD. Furthermore, Sirt1 expression was negatively correlated with the 24-h urinary protein excretion and serum creatinine levels, Banff score sums, mononuclear cell infiltration and IF severity, and TGF-beta1, MCP-1 and ICAM-1 expression levels. CONCLUSION: Sirt1 might be involved in the pathogenic process of IF and inflammation at the early stage of CRAD. Thus, Sirt1 represents a novel therapeutic strategy and target for the early prevention and treatment of CRAD. PMID- 29452172 TI - Joint evolution of dispersal propensity and site selection in structured metapopulation models. AB - We propose a novel mathematical model for a metapopulation in which dispersal occurs on two levels: juvenile dispersal from the natal site is mandatory but it may take place either locally within the natal patch or globally between patches. Within each patch, individuals live in sites. Each site can be inhabited by at most one individual at a time and it may be of high or low quality. A disperser immigrates into a high-quality site whenever it obtains one, but it immigrates into a low-quality site only with a certain probability that depends on the time within the dispersal season. The vector of these low-quality-site-acceptance probabilities is the site-selection strategy of an individual. We derive a proxy for the invasion fitness in this model and study the joint evolution of long distance-dispersal propensity and site-selection strategy. We focus on the way different ecological changes affect the evolutionary dynamics and study the interplay between global patch-to-patch dispersal and local site-selection. We show that ecological changes affect site-selection mainly via the severeness of competition for sites, which often leads to effects that may appear counterintuitive. Moreover, the metapopulation structure may result in extremely complex site-selection strategies and even in evolutionary cycles. The propensity for long-distance dispersal is mainly determined by the metapopulation-level ecological factors. It is, however, also strongly affected by the winter-survival of the site-holders within patches, which results in surprising non-monotonous effects in the evolution of site-selection due to interplay with long-distance dispersal. Altogether, our results give new additional support to the recent general conclusion that evolution of site-selection is often dominated by the indirect factors that take place via density-dependence, which means that evolutionary responses can rarely be predicted by intuition. PMID- 29452173 TI - Energy intake functions and energy budgets of ectotherms and endotherms derived from their ontogenetic growth in body mass and timing of sexual maturation. AB - Ectothermic and endothermic vertebrates differ not only in their source of body temperature (environment vs. metabolism), but also in growth patterns, in timing of sexual maturation within life, and energy intake functions. Here, we present a mathematical model applicable to ectothermic and endothermic vertebrates. It is designed to test whether differences in the timing of sexual maturation within an animal's life (age at which sexual maturity is reached vs. longevity) together with its ontogenetic gain in body mass (growth curve) can predict the energy intake throughout the animal's life (food intake curve) and can explain differences in energy partitioning (between growth, reproduction, heat production and maintenance, with the latter subsuming any other additional task requiring energy) between ectothermic and endothermic vertebrates. With our model we calculated from the growth curves and ages at which species reached sexual maturity energy intake functions and energy partitioning for five ectothermic and seven endothermic vertebrate species. We show that our model produces energy intake patterns and distributions as observed in ectothermic and endothermic species. Our results comply consistently with some empirical studies that in endothermic species, like birds and mammals, energy is used for heat production instead of growth, and with a hypothesis on the evolution of endothermy in amniotes published by us before. Our model offers an explanation on known differences in absolute energy intake between ectothermic fish and reptiles and endothermic birds and mammals. From a mathematical perspective, the model comes in two equivalent formulations, a differential and an integral one. It is derived from a discrete level approach, and it is shown to be well-posed and to attain a unique solution for (almost) every parameter set. Numerically, the integral formulation of the model is considered as an inverse problem with unknown parameters that are estimated using a series of empirical data. PMID- 29452174 TI - Dynamics analysis of epidemic and information spreading in overlay networks. AB - We establish an SIS-UAU model to present the dynamics of epidemic and information spreading in overlay networks. The overlay network is represented by two layers: one where the dynamics of the epidemic evolves and another where the information spreads. We theoretically derive the explicit formulas for the basic reproduction number of awareness R0a by analyzing the self-consistent equation and the basic reproduction number of disease R0d by using the next generation matrix. The formula of R0d shows that the effect of awareness can reduce the basic reproduction number of disease. In particular, when awareness does not affect epidemic spreading, R0d is shown to match the existing theoretical results. Furthermore, we demonstrate that the disease-free equilibrium is globally asymptotically stable if R0d<1; and the endemic equilibrium is globally asymptotically stable if R0d>1. Finally, numerical simulations show that information plays a vital role in preventing and controlling disease and effectively reduces the final disease scale. PMID- 29452175 TI - Replacement treatment during extinction training with the atypical dopamine uptake inhibitor, JHW-007, reduces relapse to methamphetamine seeking. AB - There are currently no approved medications to effectively counteract the effects of methamphetamine (METH), reduce its abuse and prolong abstinence from it. Data accumulated in recent years have shown that a range of N-substituted benztropine (BZT) analogues possesses psychopharmacological features consistent with those of a potential replacement or "substitute" treatment for stimulant addiction. On the other hand, the evidence that antidepressant therapy may effectively prevent relapse to stimulant seeking is controversial. Here, we compared in rats the ability of the BZT analogue and high affinity dopamine (DA) reuptake inhibitor, JHW-007, and the antidepressant, trazodone, administered during extinction sessions after chronic METH self-administration, to alter METH-primed reinstatement of drug seeking. The data showed that trazodone produced paradoxical effects on lever pressing during extinction of METH self administration, decreasing active, but increasing inactive, lever pressing. JHW 007 did not have any observable effects on extinction training. Importantly, JHW 007 significantly attenuated METH-primed reinstatement, whereas trazodone enhanced it. These findings lend support to the candidacy of selective DA uptake blockers, such as JHW-007, as potential treatments for METH addiction, but not to the use of antidepressant medication as a single therapeutic approach for relapse prevention. PMID- 29452176 TI - Calcium channel blocker use reduces incident dementia risk in elderly hypertensive patients: A meta-analysis of prospective studies. AB - Calcium channel blockers (CCBs) are an established class of drug for the management of hypertension. Observational studies have found that CCB use is associated with a reduction in the risk of developing dementia; however, studies have variably linked the CCBs use with the risk of dementia. This meta-analysis aims to assess whether, in elderly hypertensive patients, the use of CCBs alters the risk of developing dementia. We searched PubMed, Embase and Cochrane from August 2013 to 21st August 2017. Studies were screened on the basis of title and abstract. Quality of the included studies was assessed using the Newcastle-Ottawa Scale (NOS). The primary outcome was an estimate of the risk of dementia in elderly hypertensive CCBs users. The pooled relative risk (RR) was calculated using a generic inverse variance method. A subgroup analysis was also performed based on CCB class. Statistical analyses were performed using Review Manager Version 5.3. The meta-analysis included ten studies comprising 75,239 patients (53.16% female) with a median age and follow-up duration of 72.24 years and 8.21 years respectively. All of the studies were of high quality. The use of CCBs was associated with a significant reduction in the risk of developing dementia in elderly hypertensive patients (RR 0.70 [95% CI: 0.58-0.85] p = 0.0003) compared to those not using CCBs. In subgroup analysis we found that the dihydropyridine class was associated with a 44% [RR 0.56 (95% CI: 0.40-0.78) p = 0.0005] reduction in the dementia risk. The use of CCBs was associated with a significant reduction in the risk of developing dementia in elderly hypertensive patients. PMID- 29452177 TI - Development and validation of prediction models for the risks of diabetes-related hospitalization and in-hospital mortality in patients with type 2 diabetes. AB - OBJECTIVES: Diabetes is a major cause of hospitalization and in-hospital mortality. However, a scoring system that can be used to identify diabetic patients at risk of diabetes-related hospitalization and in-hospital mortality is lacking. METHODS: We included 32,653 patients in this retrospective cohort study. All recruited patients had type 2 diabetes, were 30-84 years of age, and were enrolled in the National Diabetes Care Management Program over the period of 2001 2003. We used the Cox proportional hazard regression model to derive risk scores. The predictive accuracy of the models was evaluated using receiver operating characteristic curves. We conducted the Hosmer-Lemeshow test to assess the agreement between predicted and observed risks. RESULTS: Over a follow-up period of eight years, 6243 patients were hospitalized for diabetes-related events, and 2048 deaths were registered in hospital records. For the one-, three-, five-, and eight-year periods, the areas under the curve (AUC) for diabetes-related hospitalization in the validation set were 0.80, 077, 0.76, and 0.74, respectively. The corresponding values for in-hospital mortality in the validation set were 0.87, 080, 0.77, and 0.76. The goodness-of-fit test showed that the predicted and observed probabilities in the one-, three-, five-, and eight-year periods were similar for diabetes-related hospitalization and in hospital mortality in the validation set (all p values > 0.05). CONCLUSION: We developed models for the estimation of the risks of diabetes-related hospitalization and in-hospital mortality in patients with type 2 diabetes. The models may be used to identify diabetic patients who are at high risk for hospital admission and in-hospital mortality. PMID- 29452178 TI - Effects of canagliflozin versus glimepiride on adipokines and inflammatory biomarkers in type 2 diabetes. AB - OBJECTIVE: Type 2 diabetes and obesity are pro-inflammatory states associated with increased risk of cardiovascular disease. Canagliflozin, an SGLT2 inhibitor, demonstrated superiority in lowering HbA1c versus glimepiride with less hypoglycemia and greater weight reduction via loss of fat mass in a 52-week trial of type 2 diabetes patients. This post hoc, exploratory analysis assessed the effects of canagliflozin versus glimepiride on select adipokines, inflammatory biomarkers, and chemokines. METHODS: Changes from baseline to Week 52 in serum leptin, adiponectin, IL-6, TNFalpha, CRP, PAI-1, VCAM-1, and MCP-1 were measured in a randomly selected subset of type 2 diabetes patients on metformin receiving canagliflozin 300 mg (n = 100) or glimepiride (n = 100) in the overall study. Correlations between change in biomarkers and change in select metabolic and anthropometric variables were assessed. RESULTS: At Week 52, canagliflozin decreased median serum leptin by 25% (95% CI: -34%, -15%) and increased median serum adiponectin by 17% (95% CI: 11%, 23%) compared with glimepiride. There was a 22% reduction in median serum IL-6 (95% CI: -34%, -10%) and a 7% increase in median serum TNFalpha (95% CI: 1%, 12%) with canagliflozin versus glimepiride. No between-group differences were observed with the other biomarkers. The decrease in serum leptin with canagliflozin was correlated with change in weight (r >= 0.3) only; the increase in adiponectin and decrease in IL-6 with canagliflozin occurred independently of changes in HbA1c, weight, or lipids. CONCLUSIONS: These results indicate that canagliflozin may improve adipose tissue function and induce changes in serum leptin, adiponectin, and IL-6 that favorably impact insulin sensitivity and cardiovascular disease risk. PMID- 29452179 TI - Massively parallel C. elegans tracking provides multi-dimensional fingerprints for phenotypic discovery. AB - BACKGROUND: The nematode worm C. elegans is a model organism widely used for studies of genetics and of human disease. The health and fitness of the worms can be quantified in different ways, such as by measuring their bending frequency, speed or lifespan. Manual assays, however, are time consuming and limited in their scope providing a strong motivation for automation. NEW METHOD: We describe the development and application of an advanced machine vision system for characterising the behaviour of C. elegans, the Wide Field-of-View Nematode Tracking Platform (WF-NTP), which enables massively parallel data acquisition and automated multi-parameter behavioural profiling of thousands of worms simultaneously. RESULTS: We screened more than a million worms from several established models of neurodegenerative disorders and characterised the effects of potential therapeutic molecules for Alzheimer's and Parkinson's diseases. By using very large numbers of animals we show that the sensitivity and reproducibility of behavioural assays is very greatly increased. The results reveal the ability of this platform to detect even subtle phenotypes. COMPARISON WITH EXISTING METHODS: The WF-NTP method has substantially greater capacity compared to current automated platforms that typically either focus on characterising single worms at high resolution or tracking the properties of populations of less than 50 animals. CONCLUSIONS: The WF-NTP extends significantly the power of existing automated platforms by combining enhanced optical imaging techniques with an advanced software platform. We anticipate that this approach will further extend the scope and utility of C. elegans as a model organism. PMID- 29452180 TI - The M-Maze task: An automated method for studying fear memory in rats exposed to protracted aversive conditioning. AB - BACKGROUND: Fear conditioning (FC) in rodents is the most used animal model to investigate the neurobiology of posttraumatic stress disorder (PTSD). Although research using FC has generated a better understanding of fear memories, studies often rely on mild or moderate FC training and behavioral analysis generally focuses on measuring freezing responses within few test sessions. NEW METHOD: We introduce the M-Maze task, a system that measures extinction of conditioned fear using suppression of operant behavior. The apparatus consists of an M-shaped maze where rats are trained to alternate nose poking at two pellet dispensers. Proximity sensors measure the animal's locomotion, as well as the latencies and number of operant behaviors. Here we also describe the protracted aversive conditioning (PAC), a rat model of severe fear that induces resistant extinction following a 4-day conditioning protocol that combines delay, unpredictable, and short- and long-trace conditioning. RESULTS: An intense one-day auditory FC protocol induced a sharp elevation in transit time and suppression of nose pokes by conditioned cues, but in contrast to what is found in PTSD patients, fear extinction was rapidly observed. On the other hand, PAC alone or in combination with exposure to single prolonged stress induced persistent extinction impairments in M-Maze tests, as well as enhanced anxiety, and social withdrawal. COMPARISON WITH OTHER EXISTING METHODS: The M-Maze task is fully automated and allows multiple animals to be tested simultaneously in long-term experiments. Moreover, PAC training can be an alternative approach to study extinction resistant fear. CONCLUSIONS: The M-Maze task allows rapid and unbiased measurements of fear-induced suppression. We suggest that long-term assessment of extinction impairments would lead to a better understanding of the neurobiology of persistent fear and the screening for new therapies. PMID- 29452181 TI - The demosponge Pseudoceratina purpurea as a new source of fibrous chitin. AB - Among marine demosponges (Porifera: Demospongiae), only representatives of the order Verongiida have been recognized to synthetize both biologically active substances as well as scaffolds-like fibrous skeletons made of structural aminopolysaccharide chitin. The unique 3D architecture of such scaffolds open perspectives for their applications in waste treatment, biomimetics and tissue engineering. Here, we focus special attention to the demosponge Pseudoceratina purpurea collected in the coastal waters of Singapore. For the first time the detailed description of the isolation of chitin from the skeleton of this sponge and its identification using diverse bioanalytical tools were carried out. Calcofluor white staining, FTIR analysis, electrospray ionization mass spectrometry (ESI-MS), SEM, and fluorescence microscopy as well as a chitinase digestion assay were applied in order to confirm with strong evidence the finding of alpha-chitin in the skeleton of P. purpurea. We suggest that the discovery of chitin within representatives of Pseudoceratinidae family is a perspective step in evaluation of these verongiid sponges as novel renewable sources for both chitin and biologically active metabolites, which are of prospective use for marine oriented biomedicine and pharmacology, respectively.

AB - Intelligent hydrogels are attractive biomaterials for various applications, however, fabricating a hydrogel with both adequate self-healing ability and mechanical properties remains a challenge. Herein, a series of novel intelligent konjac glucomannan (KGM)/microcrystalline cellulose (MCC) hydrogels were prepared vis the mussel-inspired chemistry. MCC was firstly functionalized by the oxidative polymerization of dopamine, and the intelligent hydrogels were obtained by mixing aqueous solutions of KGM and functionalized MCC (PDMCC). By introducing PDMCC, a more compact interconnected porous structure formed for the resulting hydrogels. The self-healing ability and mechanical properties of intelligent hydrogels were dependence on the PDMCC content. Compared with KGM hydrogels, KGM/PDMCC hydrogels exhibited a more distinct pH sensitivity and a lower initial burst release, which was attributed to the compact structure and strong intermolecular hydrogen bond interaction between PDMCC and KGM. These results suggest that the KGM/PDMCC intelligent hydrogels may be promising carriers for controlled drug delivery. PMID- 29452183 TI - Purification, structural elucidation, and anti-inflammatory activity of xylosyl galactofucan from Armillaria mellea. AB - A xylosyl 1,3-galactofucan (AMPS-III) was isolated and identified as a novel anti inflammatory agent from an edible fungus, Armillaria mellea. The characteristics chemical structure of AMPS-III including the linkages of compositional monosaccharides and structure of the repeat unit were depicted and elucidated by proton, carbon and two-dimensional nuclear magnetic resonance techniques. AMPS III was chemically proposed to have a partial 4-O-xylosylated 1,3-linked alpha-d galactosyl-interlaced alpha-l-fucan composed of a pentadecasaccharide repeat unit with a molecular mass approximately 13 kDa. AMPS-III significantly suppressed the release of tumor necrosis factor-alpha (TNF-alpha) and cytokine monocyte chemotactic protein-1 (MCP-1) in RAW264.7 macrophages and EAhy926 following LPS and TNF-alpha induction. The results provide helpful evidences for application of AMPS-III as anti-inflammatory food supplements. PMID- 29452184 TI - Production of chitinase from Escherichia fergusonii, chitosanase from Chryseobacterium indologenes, Comamonas koreensis and its application in N acetylglucosamine production. AB - The important platform polysaccharide N-acetylglucosamine (GlcNAc) has great potential to be used in the fields of food, cosmetics, agricultural, pharmaceutical, medicine and biotechnology. This GlcNAc is being produced by traditional methods of environment-unfriendly chemical digestion with strong acids. Therefore, researchers have been paying more attention to enzymatic hydrolysis process for the production of GlcNAc. Hence, in this study, we isolated novel chitinase (Escherichia fergusonii) and chitosanase (Chryseobacterium indologenes, Comamonas koreensis) producing strains from Korean native calves feces, and developed the potential of an eco-friendly microbial progression for GlcNAc production from swollen chitin and chitosan by enzymatic degradation. Maximum chitinase (7.24+/-0.07U/ml) and chitosanase (8.42+/-0.09, 8.51+/-0.25U/ml) enzyme activity were reached in submerged fermentation at an optimal pH of 7.0 and 30 degrees C. In this study, sucrose, yeast extract, (NH4)2SO4, and NaCl were found to be the potential enhancers of exo-chitinase activity and glucose, corn flour, yeast extract, soybean flour, (NH4)2SO4, NH4Cl and K2HPO4 were found to be the potential activator for exo-chitosanase activity. Optimum concentrations of the carbon sources for enhanced chitinase activity were 9.91, 3.21, 9.86, 1.66U/ml and chitosanase activity were 1.63, 1.13, 2.28, 3.71, 9.02, 4.93, and 2.14U/ml. These enzymes efficiently hydrolyzed swollen chitin and chitosan to N-acetylglucosamine were characterized by thin layer chromatography and were further confirmed by high-pressure liquid chromatography. From a commercial perspective, we isolated, optimized and characterized exochitinase from Escherichia fergusonii (HANDI 110) and chitosanase from Chryseobacterium indologenes (HANYOO), and Comamonas koreensis (HANWOO) for the large-scale production of GlcNAc facilitating its potential use in industrial applications. PMID- 29452185 TI - An injectable chitosan/chondroitin sulfate hydrogel with tunable mechanical properties for cell therapy/tissue engineering. AB - Chitosan (CH) hydrogels with remarkable mechanical properties and rapid gelation rate were recently synthesized by combining sodium hydrogen carbonate (SHC) with another weak base, such as beta-glycerophosphate (BGP). To improve their biological responses, in the present study, chondroitin sulfate (CS) was added to these CH hydrogels. Hydrogel characteristics in terms of pH and osmolarity, as well as rheological, mechanical, morphological and swelling properties, were studied in the absence and presence of CS. Effect of CS addition on cytocompatibility of hydrogels was also assessed by evaluating the viability and metabolic activity of encapsulated L929 fibroblasts. New CH hydrogels containing CS were thermosensitive and injectable with pH and osmolality close to physiological levels and enhanced swelling capacity. Encapsulated cells were able to maintain their viability and proliferative capacity up to 7 days and CS addition improved the viability of the cells, particularly in serum-free conditions. Addition of CS showed a reducing and dose-dependent effect on the mechanical strength of the hydrogels after complete gelation. This work provides evidence that CH-CS hydrogels prepared with a combination of SHC and BGP as a gelling agent have a promising potential to be used as thermosensitive, injectable and biocompatible matrices with tunable mechanical properties for cell therapy applications. PMID- 29452186 TI - Lectin obtained from the red seaweed Bryothamnion triquetrum: Secondary structure and anti-inflammatory activity in mice. AB - Seaweeds are sources of biomolecules with biological activities and pharmacological potential - for example, lectins, a group of proteins that can bind reversibly to carbohydrates or compounds containing them. The aim of this study was to elucidate the structural properties of a lectin extracted from the red seaweed Bryothamnion triquetrum (BtL) and to investigate its anti inflammatory activity in mice. The lectin was purified by precipitation with ammonium sulfate and ion-exchange chromatography. Its secondary structure and tryptophan (Trp) microenvironment were analyzed by circular dichroism spectroscopy and steady-state fluorescence spectroscopy, respectively. The anti inflammatory effect was evaluated by means of paw edema induced by carrageenan or dextran, myeloperoxidase activity in paw tissue, and by measurement of leukocyte and neutrophil migration and cytokine quantification in a peritonitis model. The secondary structure of BtL is mostly composed of beta-strands and unordered conformation, and it is quite resistant to extremes of pH and temperature, preserving the exposure of Trp residues under these conditions. In an assessment of biological activities, groups of mice were subjected to pretreatment with BtL before the inflammatory stimulus. BtL had anti-inflammatory effects in the models tested, and hence may be considered a molecule with potential to be used in the pharmaceutical industry. PMID- 29452187 TI - Purification of extra cellular poly-gamma-glutamic acid as an antibacterial agent using anion exchange chromatography. AB - BLAST analysis of the 16S rRNA gene sequence for the newly isolated bacterium, revealed significant identity (99.5%) with Bacillus sonorensis [Ijadi Bajestani, M., et al., International Journal of Biological Macromolecules, 2017. 96: p. 100 110]. According to the literature review for closely related species of Bacillus sonorensis, the production of poly-gamma-glutamic acid (gamma-PGA) as an extra cellular biopolymer was investigated for the isolated bacteria which is deposited in IBRC (Iranian Biological Resource Center) as Bacillus sp. Strain M2 (IBRC M11173). To determine if gamma-PGA production by Bacillus sp. Strain M2 is glutamate dependent, it was grown on PGA medium, consisted of sodium glutamate. The results proved that gamma-PGA production is highly dependent on glutamate component. In the following, the bioproduct has undergone different purification processes mainly consisting of dialysis, deproteinization and anion exchange chromatography. Based on the high-performance liquid chromatography (HPLC) results for ion chromatography effluents, 59% of the initial PGA in main solution was eluted via NaCl elution. Gel permeation chromatography (GPC) characterization analysis was accomplished to determine the polydispersity and gamma-PGA molecular weight. Two major average molecular weights were distinguished; the heavy weight fraction of 7.7*106g/mol with polydispersity index of 1.73 and the other one with an average molecular weight number of 1.7*104g/mol and polydispersity index of 4.4. The antibacterial activity of the extracellular gamma-PGA, as an anionic biopolymer, toward Staphylococcus aureus and E. coli, was assayed using the clinical and laboratory standards institute (CLSI) guidelines. For Staphylococcus aureus the minimum inhibitory concentration (MIC) value was about 34g/L while for E. coli this value reaches 53g/L. PMID- 29452188 TI - Phosphate fertilization changes the characteristics of 'Maca' banana starch. AB - The unripe banana has been studied as a potential source of starch for use in various applications. Considering the importance of phosphorus in the biosynthesis of the starch and also the interference of this mineral in starch properties, in this study it was evaluated the effect of rates of phosphate fertilizer applied in the cultivation of 'Maca' banana on the characteristics of the starch. Starches extracted from fruits from different treatments were analyzed for morphological characteristics, X-ray diffraction pattern, relative crystallinity, granule size, amylose, resistant starch and phosphorus levels, as well as, for pasting and thermal properties. Results showed that the phosphate fertilization has interference on the characteristics of the banana starch led to increase of phosphorus content and size of the granules, reduction of crystallinity and resistant starch content, decrease of viscosity peak, breakdown, final viscosity, setback, transitions temperatures and enthalpy. These changes caused by phosphate fertilizer conditions can be increase the applications of the 'Maca' banana starch. PMID- 29452189 TI - Roasted and green coffee extracts show antioxidant and cytotoxic activity in myoblast and endothelial cell lines in a cell specific manner. AB - Coffee is one of the most highly consumed beverages with potential beneficial health implications, however its molecular mechanism of action has not been completely elucidated yet. To that cause, the polyphenolic composition of different coffee extracts (from Light, Medium and Dark roasts as well as green beans) was examined by UHPLC-HRMS analysis, indicating chlorogenic acids isomers as the main constituents. In the following step, the toxicity of the extracts was tested in myoblasts and endothelial cells and differential toxicity of green and roasted samples was displayed as the myoblasts were more sensitive to green coffee extracts, in contrast to the endothelial cells. Subsequently, biologically relevant, non-cytotoxic extract concentrations were administered to explore their potential effect on cell redox status using flow cytometry and spectrophotometric assays. The results indicated that all coffee extracts improved cell redox status, however differences were observed between the two different cell lines tested, implying that coffee compounds display cell- and tissue-specificity. Glutathione levels were increased in almost all cases up to 70%, while the roasting degree affected the free radical scavenging potential of the extracts and their ability to protect from macromolecular oxidation as exhibited by the differences in ROS, CARB and TBARS levels, especially in the myoblasts. PMID- 29452190 TI - Toxicity assessment of mycotoxins extracted from contaminated commercial dog pelleted feed on canine blood mononuclear cells. AB - Raw ingredients of pet food are often contaminated with mycotoxins. This is a serious health problem to pets and causes emotional and economical stress to the pet owners. The aim of this study was to determine the immunotoxicity of the most common mycotoxins (aflatoxin, fumonisin, ochratoxin A and zearalenone) by examining 20 samples of extruded dry dog food found on the South African market [10 samples from standard grocery store lines (SB), 10 from premium veterinarian lines (PB)]. Pelleted dog food was subjected to extraction protocols optimized for the above mentioned mycotoxins. Dog lymphocytes were treated with the extracts (24 h incubation and final concentration 40 MUg/ml) to determine cell viability, mitochondrial function, oxidative stress, and markers of cell death using spectrophotometry, luminometry and flow cytometry. Malondialdehyde, a marker of oxidative stress showed no significant difference between SB and PB, however, GSH was significantly depleted in SB extract treatments. Markers of apoptosis (phosphatidylserine externalization) and necrosis (propidium iodide incorporation) were elevated in both food lines when compared to untreated control cells, interestingly SB extracts were significantly higher than PB. We also observed decreased ATP levels and increased mitochondrial depolarization in cells treated with both lines of feed with SB showing the greatest differences when compared to the control. This study provides evidence that irrespective of price, quality or marketing channels, pet foods present a high risk of mycotoxin contamination. Though in this study PB fared better than SB in regards to cell toxicity, there is a multitude of other factors that need to be studied which may have an influence on other negative outcomes. PMID- 29452191 TI - Recent advances of medical foods in China: The opportunities and challenges under standardization. AB - Malnutrition with high incidence in hospitalized patients in China has brought a significant burden of disease. Although many clinical studies have demonstrated the importance of nutritional for patients with malnutrition, the application of medical foods in China is still restricted. For the classification, limits, production and registration of medical foods, the Chinese government newly enacted a series of regulations. In this review, comparing the policy, researches, and product variety of medical foods in China with other countries, although the current status of the development of medical foods in China is still far behind that of developed countries, some of regulations are stricter than those of many other countries or organizations. The medical foods in China are divided into four categories, the nutrients and environmental contaminants are limited to ensure the safety. As a prospect, the development of medical foods in China is expected to get out of the predicament of lack of emphasis, shortage of supply, backward of local processing technology and the imperfect management system. After all, in view of the huge population and the increasing demand of nutrition in China, there must be a very good prospect for the future development of the medical foods industry in China. PMID- 29452192 TI - Graded 6-OHDA-induced dopamine depletion in the nigrostriatal pathway evokes progressive pathological neuronal activities in the subthalamic nucleus of a hemi parkinsonian mouse. AB - Recent studies have established methods for establishing a rodent model that mimics progressive stages of human Parkinson's disease (PD), via injection of graded doses of 6-hydroxydopamine (6-OHDA) into regions within the nigrostriatal pathway. However, the electrophysiological characteristics of the subthalamic nucleus (STN) in this model have not been fully elucidated in this model. This study aimed to investigate changes in the neuronal activity of the STN in a graded mouse model of PD. Increasing doses of 6-OHDA were unilaterally injected into the medial forebrain bundle (MFB) to produce a hemi-parkinsonian mouse model, mimicking early, moderate, advanced, and severe stages of human PD. Mice treated with higher doses of 6-OHDA demonstrated significantly lower rates of use of the impaired (contralateral) forelimb during wall contact, relative to sham mice. The STN firing rate was significantly increased in groups with >75% dopaminergic cell loss in the substantia nigra pars compacta (SNc), whereas little increase was observed in groups with partial lesions of the SNc, relative to the sham group. In addition, firing patterns of the STN in groups treated with higher doses of 6-OHDA became more irregular and exhibited burst-like patterns of activity, with dominant slow wave oscillations in the frequency range of 0.3-2.5 Hz. Our results demonstrated a strong correlation between neuronal activities in the STN and dopamine depletion in the nigrostriatal pathway, which can be manipulated by variation of 6-OHDA doses. PMID- 29452193 TI - Antidepressant activity of vorinostat is associated with amelioration of oxidative stress and inflammation in a corticosterone-induced chronic stress model in mice. AB - Major depressive disorder (MDD) is a multifactorial neuropsychiatric disorder. Chronic administration of corticosterone (CORT) to rodents is used to mimic the stress associated dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis, a well-established feature found in depressive patients. Recently, preclinical studies have demonstrated the antidepressant potential of histone deacetylase (HDAC) inhibitors. So, we examined the antidepressant potential of vorinostat (VOR), a HDAC inhibitor against CORT injections in male mice. VOR (25 mg/kg; intraperitoneal) and fluoxetine (FLX) (15 mg/kg; oral) treatments were provided to CORT administered mice. At the end of dosing schedule, neurobehavioral tests were conducted; followed by mechanistic evaluation through biochemical analysis, RTPCR and western blot in serum and hippocampus. Neurobehavioral tests revealed the development of anxiety/depressive-like behavior in CORT mice as compared to the vehicle control. Depressive-mice showed concomitant HPA axis dysregulation as observed from the significant increase in serum CORT and ACTH. Chronic CORT administration was found to significantly increase hippocampal malondialdehyde (MDA) and iNOS levels while lowering glutathione (GSH) content, as compared to vehicle control. VOR treatment, in a similar manner to the classical antidepressant FLX, significantly ameliorated anxiety/depressive-like behavior along with HPA axis alterations induced by CORT. The antidepressant-like ability of drug treatments against chronic CORT induced stress model, as revealed in our study, may be due to their potential to mitigate inflammatory damage and oxidative stress via modulation of hippocampal NF-kappaB p65, COX-2, HDAC2 and phosphorylated JNK levels. PMID- 29452194 TI - Decompressive craniectomy protects against hippocampal edema and behavioral deficits at an early stage of a moderately controlled cortical impact brain injury model in adult male rats. AB - A decompressive craniectomy (DC) has been shown to be a life-saving therapeutic treatment for traumatic brain injury (TBI) patients, which also might result in post-operative behavioral dysfunction. However, there is still no definite conclusion about whether the behavioral dysfunction already existed at an early stage after the DC operation or is just a long-term post-operation complication. Therefore, the aim of the present study was to analyze whether DC treatment was beneficial to behavioral function at an early stage post TBI. In this study, we established a controlled cortical impact injury rat model to evaluate the therapeutic effect of DC treatment on behavioral deficits at 1 d, 2 d, 3 d and 7 d after TBI. Our results showed that rats suffered significant behavioral and mood deficits after TBI compared to the control group, while decompressive craniectomy treatment could normalize MMP-9 expression levels and reduce hippocampal edema formation, stabilize the expression of Synapsin I, which was a potential indicator of maintaining the hippocampal synaptic function, thus counteracting behavioral but not mood decay in rats subjected to TBI. In conclusion, decompressive craniectomy, excepting for its life-saving effect, could also play a potential beneficial neuroprotective role on behavioral but not mood deficits at an early stage of moderate traumatic brain injury in rats. PMID- 29452195 TI - Construction and evaluation of the immune protection of a recombinant divalent protein composed of the MrpA from MR/P fimbriae and flagellin of Proteus mirabilis strain against urinary tract infection. AB - Urinary tract infections (UTI) caused by Proteus mirabilis are prevalent among the catheterized patients. There is no effective vaccine to reduce the frequency of UTIs caused by P. mirabilis. In the present study, the immune responses and effectiveness of different combinations of MrpA and flagellin (FliC) of P. mirabilis were assessed intranasally in the mice model. The addition of FliC as adjuvant to MrpA in fusion form significantly raised the mucosal IgA and cellular (IFN-gamma and IL-17) responses and maintained the serum IgG responses for 180 days after the first vaccination. Furthermore, MrpA in fusion form with FliC significantly increased the systemic, mucosal and IFN-gamma responses of the FliC alone. In a bladder challenge assay with P. mirabilis, the fusion MrpA.FliC and the mixture of MrpA and FliC significantly decreased the colony count of the bacteria in the bladder and kidneys of mice in comparison to the control mice. It suggests a complex of the systemic, mucosal and cellular responses are needed for protection of the bladder and kidneys against P. mirabilis UTI. In our knowledge, the adjuvant property of the recombinant P. mirabilis flagellin was evaluated for the first time in a vaccine combination administered by an intranasal route. Our results suggest the recombinant flagellin of P. mirabilis could be used as an intranasal adjuvant in combination with other potential antigens against UTIs. PMID- 29452196 TI - Staphylococcus aureus induces TGF-beta1 and bFGF expression through the activation of AP-1 and NF-kappaB transcription factors in bovine mammary epithelial cells. AB - Staphylococcus aureus is a common Gram-positive pathogen that causes bovine mastitis, a persistent infection of the bovine mammary gland. Bovine mammary epithelial cells (BMEC) are important parenchymal cells of the bovine mammary gland. To better understand the importance of BMEC and the roles of the TLR-NF kappaBand TLR-AP-1 signaling pathways in the regulation of S. aureus-associated mastitis and mammary fibrosis, BMEC cultured in vitro were stimulated with different concentrations of heat-inactivated S. aureus to analyze the gene and protein expression and production of toll-like receptor 2 (TLR2), toll-like receptor 4 (TLR4), transforming growth factor beta 1 (TGF-beta1), basic fibroblast growth factor (bFGF) as well as the protein expression of nuclear factor-kappa B (NF-kappaB) and activation protein-1 (AP-1) by means of quantitative polymerase chain reaction (qPCR) and western blotting, respectively. Specific NF-kappaB and AP-1 inhibitors were also used to investigate their effects on the regulation of TGF-beta1 and bFGF expression. The results indicated that, in addition to increasing mRNA expression and secretion of TLR2 and TLR4, S. aureus could also upregulate TGF-beta1 and bFGF mRNA expression and secretion through the activation of NF-kappaB and AP-1. The increase in TGF-beta1 and bFGF expression was shown to be inhibited by AP-1- and NF-kappaB-specific inhibitors. Taken together, S. aureus induces TGF-beta1 and bFGF expression through the activation of AP-1 and NF-kappaB in BMECs. This information offers new potential targets for the treatment of bovine mammary fibrosis. PMID- 29452197 TI - Essential oils from Origanum vulgare and Salvia officinalis exhibit antibacterial and anti-biofilm activities against Streptococcus pyogenes. AB - In the present study, essential oils (EOs) extracted from oregano, sage, cloves, and ginger were evaluated for the phytochemical profile, antibacterial, and anti biofilm activities against Streptococcus pyogenes. The broth microdilution method was used to determine the minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) of EOs. The minimum biofilm inhibitory concentrations (MBICs) were determined using MTT assay and fixed biofilms were observed through scan electron microscopy. The oregano and sage EOs showed the lowest MIC as well as MBC of 0.25-0.5 mg/mL. Time kill assay results showed that oregano and sage EOs exhibited bactericidal effects within 5 min and 4 h, respectively. Both oregano and sage extracts acts as a potent anti-biofilm agent with dual actions, preventing and eradicating the biofilm. The microscopic visualization of biofilms treated with EOs have shown morphological and density changes compared to the untreated control. Oregano EO was constituted predominantly carvacrol (91.6%) and in sage EO, higher levels of alpha-thujone (28.5%) and camphor (16.6%) were revealed. EOs of oregano and sage inhibit the growth and biofilm formation of S. pyogenes. Effective concentrations of oregano and sage EOs and their phytochemicals can be used in developing potential plant derived antimicrobial agents in the management of streptococcal pharyngitis. PMID- 29452198 TI - Microbial infection pattern, pathogenic features and resistance mechanism of carbapenem-resistant Gram negative bacilli during long-term hospitalization. AB - BACKGROUND: Carbapenem-resistant Gram-negative bacilli (GNB) have become an important cause of nosocomial infections of hospitalized patients. METHODS: To investigate the microbial infection patterns and molecular epidemiology characteristics of the carbapenem-resistant GNB isolates from a long-term hospitalized patient, antimicrobial susceptibility testing, phenotypic screening test for carbapenemase production, PCR screening and DNA sequencing of carbapenemase genes, repetitive extragenic palindromic sequence-based PCR (REP PCR), multilocus sequencing typing (MLST) and genetic environment analysis were performed. RESULTS: Twelve strains with carbapenemase genes were detected from 63 carbapenem-resistant isolates, including two blaIMP-25-carrying Pseudomonas aeruginosa, one blaNDM-1-carrying Citrobacter freundii, three blaNDM-1-carrying Klebsiella pneumoniae and six blaKPC-2-carrying K. pneumoniae. Only the blaNDM-1 genes were successfully transferred from three K. pneumoniae strains to Escherichia coli C600 by conjugation. Genetic environment of blaIMP-25, blaNDM-1 and blaKPC-2 genes in our study were consistent with previous reports. Molecular typing of K. pneumoniae performed by MLST revealed that most of the isolates belonged to ST11. blaNDM-1-carrying K. pneumoniae sequencing type 1416 was first reported in our study. CONCLUSIONS: Carbapenem-resistant GNB are common pathogens during long-term hospitalization, and ST11 blaKPC-2-carrying K. pneumoniae is the dominant bacterium in our study. Colonization and horizontal transmission of resistance by plasmids of carbapenem-resistant GNB have increased the risks of persistent infection and mortality of long-term hospitalized patients.

PMID- 29452201 TI - The nasal microbiome in patients with chronic rhinosinusitis: Analyzing the effects of atopy and bacterial functional pathways in 111 patients. PMID- 29452199 TI - Establishment of the nasal microbiota in the first 18 months of life: Correlation with early-onset rhinitis and wheezing. AB - BACKGROUND: Dynamic establishment of the nasal microbiota in early life influences local mucosal immune responses and susceptibility to childhood respiratory disorders. OBJECTIVE: The aim of this case-control study was to monitor, evaluate, and compare development of the nasal microbiota of infants with rhinitis and wheeze in the first 18 months of life with those of healthy control subjects. METHODS: Anterior nasal swabs of 122 subjects belonging to the Growing Up in Singapore Towards Healthy Outcomes (GUSTO) birth cohort were collected longitudinally over 7 time points in the first 18 months of life. Nasal microbiota signatures were analyzed by using 16S rRNA multiplexed pair-end sequencing from 3 clinical groups: (1) patients with rhinitis alone (n = 28), (2) patients with rhinitis with concomitant wheeze (n = 34), and (3) healthy control subjects (n = 60). RESULTS: Maturation of the nasal microbiome followed distinctive patterns in infants from both rhinitis groups compared with control subjects. Bacterial diversity increased over the period of 18 months of life in control infants, whereas infants with rhinitis showed a decreasing trend (P < .05). An increase in abundance of the Oxalobacteraceae family (Proteobacteria phylum) and Aerococcaceae family (Firmicutes phylum) was associated with rhinitis and concomitant wheeze (adjusted P < .01), whereas the Corynebacteriaceae family (Actinobacteria phylum) and early colonization with the Staphylococcaceae family (Firmicutes phylum; 3 weeks until 9 months) were associated with control subjects (adjusted P < .05). The only difference between the rhinitis and control groups was a reduced abundance of the Corynebacteriaceae family (adjusted P < .05). Determinants of nasal microbiota succession included sex, mode of delivery, presence of siblings, and infant care attendance. CONCLUSION: Our results support the hypothesis that the nasal microbiome is involved in development of early onset rhinitis and wheeze in infants. PMID- 29452202 TI - Effectiveness of indoor allergen reduction in asthma management: A systematic review. AB - BACKGROUND: This review will inform updated National Asthma Education and Prevention Program clinical practice guidelines. OBJECTIVE: We sought to evaluate the effectiveness of allergen reduction interventions on asthma outcomes. METHODS: We systematically searched the "gray literature" and 5 bibliographic databases. Eligible studies included systematic reviews, randomized controlled trials, and nonrandomized interventional studies. Risk of bias was assessed by using the Cochrane Risk of Bias instrument and the Newcastle-Ottawa scale. The evidence base was assessed by using the approach of the Agency for Healthcare Research and Quality's Evidence-based Practice Center program. RESULTS: Fifty nine randomized and 8 nonrandomized trials addressed 8 interventions: acaricide, air purification, carpet removal, high-efficiency particulate air filtration (HEPA) vacuums, mattress covers, mold removal, pest control, and pet removal. Thirty-seven studies evaluated single-component interventions, and 30 studies assessed multicomponent interventions. Heterogeneity precluded meta-analysis. For most interventions and outcomes, the evidence base was inconclusive or showed no effect. No interventions were associated with improvement in validated asthma control measures or pulmonary physiology. Exacerbations were diminished in multicomponent studies that included HEPA vacuums or pest control (moderate strength of evidence [SOE] for both). Quality of life improved in studies of air purifiers (SOE: low) and in multicomponent studies that included HEPA vacuums (SOE: moderate) or pest control (SOE: low). CONCLUSIONS: Single interventions were generally not associated with improvement in asthma measures, with most strategies showing inconclusive results or no effect. Multicomponent interventions improved various outcomes, but no combination of specific interventions appears to be more effective. The evidence was often inconclusive because of a lack of studies. Further research is needed comparing the effect of indoor allergen reduction interventions on validated asthma measures, with sufficient population sizes to detect clinically meaningful differences. PMID- 29452203 TI - Morphology of the elytral base sclerites. AB - The elytral base sclerites (= sclerites located at the articular region between the forewing and thorax in Coleoptera) of selected taxa were examined and homologized. Although the elytral base sclerites are highly modified compared to the wing base sclerites of the other neopterans, they can be homologized by using the conservative wing flapping and folding lines as landmarks. A reduction of the first axillary sclerite was identified as a general trend of the elytral base sclerites, although the sclerite usually has a very important function to mediate flight power from the notum to the wing. This result indicates that the functional constraint against the basal sclerites is relaxed because of the lack of an ability to produce flight power by elytra. In contrast, the elytral folding system formed by the basal sclerites is well retained, which probably occurs because proper wing folding is a key for the shelter function of the elytra. The elytral base sclerites apparently contain more homoplasies than the serially homologous hindwing base sclerites of Coleoptera, which suggests that the structure is less useful for higher-level systematics. However, the faster evolutionary rate of the elytral base sclerites suggests there is potential for studying the lower-level phylogeny of Coleoptera. PMID- 29452204 TI - Antiviral therapy in hepatitis B virus-infected children with immune-tolerant characteristics: A pilot open-label randomized study. AB - BACKGROUND & AIM: Chronic infection with hepatitis B virus (HBV) in children is a serious health problem worldwide. How to treat children with immune-tolerant chronic hepatitis B infection, commonly characterized by hepatitis B e antigen (HBeAg) positivity, high viral load, normal or mildly elevated alanine aminotransferase and no or minimal inflammation in liver histology, remains unresolved. This trial aims to study the benefits of antiviral therapy in children with these characteristics. METHODS: This is a pilot open-label randomized controlled study. From May 2014 to April 2015, 69 treatment-naive chronically HBV-infected children, aged 1 to 16 years, who had immune-tolerant characteristics were recruited to this trial and randomly assigned, in a 2:1 ratio, to treatment group and control group. Patients in the treatment group received either interferon-alpha (IFN) monotherapy or consecutively received IFN monotherapy, combination therapy of IFN and lamivudine (LAM), and LAM therapy alone. All patients were observed until week 96. RESULTS: At baseline, epidemiological, biochemical, serological, virological and histological indices were consistent across the treatment and control groups. Of the 46 patients in the treatment group, 73.91% had undetectable serum HBV DNA, 32.61% achieved HBeAg seroconversion and 21.74% lost hepatitis B surface antigen (HBsAg) at the endpoint. No LAM resistance emerged at week 96. In the control group, only one (4.35%) patient underwent spontaneous HBeAg seroconversion and had undetectable serum HBV DNA during observation, and moreover, none developed HBsAg clearance. For all patients, no serious adverse events were observed. CONCLUSION: Antiviral treatment with a sequential combination of IFN and LAM resulted in a significant improvement in the rates of undetectable serum HBV DNA, HBeAg seroconversion and HBsAg loss in children with chronic HBV infection and immune-tolerant characteristics. LAY SUMMARY: There is a lack of data regarding treatment of immune-tolerant chronic hepatitis B (CHB). It remains unresolved how children with immune-tolerant CHB should be treated. This paper reports the outcomes from a pilot open-label randomized controlled trial on antiviral therapy in children with immune-tolerant characteristics. It shows that a sequential combination of interferon-alpha and lamivudine was beneficial. PMID- 29452205 TI - Impaired cerebral microcirculation induced by ammonium chloride in rats is due to cortical adenosine release. AB - BACKGROUND & AIMS: Liver failure results in hyperammonaemia, impaired regulation of cerebral microcirculation, encephalopathy, and death. However, the key mediator that alters cerebral microcirculation remains unidentified. In this study we show that topically applied ammonium significantly increases periarteriolar adenosine tone on the brain surface of healthy rats and is associated with a disturbed microcirculation. METHODS: Cranial windows were prepared in anaesthetized Wistar rats. The flow velocities were measured by speckle contrast imaging and compared before and after 30 min of exposure to 10 mM ammonium chloride applied on the brain surface. These flow velocities were compared with those for control groups exposed to artificial cerebrospinal fluid or ammonium plus an adenosine receptor antagonist. A flow preservation curve was obtained by analysis of flow responses to a haemorrhagic hypotensive challenge and during stepwise exsanguination. The periarteriolar adenosine concentration was measured with enzymatic biosensors inserted in the cortex. RESULTS: After ammonium exposure the arteriolar flow velocity increased by a median (interquartile range) of 21.7% (23.4%) vs. 7.2% (10.2%) in controls (n = 10 and n = 6, respectively, p <0.05), and the arteriolar surface area increased. There was a profound rise in the periarteriolar adenosine concentration. During the hypotensive challenge the flow decreased by 27.8% (14.9%) vs. 9.2% (14.9%) in controls (p <0.05). The lower limit of flow preservation remained unaffected, 27.7 (3.9) mmHg vs. 27.6 (6.4) mmHg, whereas the autoregulatory index increased, 0.29 (0.33) flow units per millimetre of mercury vs. 0.03 (0.21) flow units per millimetre of mercury (p <0.05). When ammonium exposure was combined with topical application of an adenosine receptor antagonist, the autoregulatory index was normalized. CONCLUSIONS: Vasodilation of the cerebral microcirculation during exposure to ammonium chloride is associated with an increase in the adenosine tone. Application of a specific adenosine receptor antagonist restores the regulation of the microcirculation. This indicates that adenosine could be a key mediator of the brain dysfunction seen during hyperammonaemia and is a potential therapeutic target. LAY SUMMARY: In patients with liver failure, disturbances in brain function are caused in part by ammonium toxicity. In our project we studied how ammonia, through adenosine release, affects the blood flow in the brain of rats. In our experimental model we demonstrated that the detrimental effect of ammonia on blood flow regulation was counteracted by blocking the adenosine receptors in the brain. With this observation we identified a novel potential treatment target. If we can confirm our findings in a future clinical study, this might help patients with liver failure and the severe condition called hepatic encephalopathy. PMID- 29452206 TI - SNX10 mediates alcohol-induced liver injury and steatosis by regulating the activation of chaperone-mediated autophagy. AB - BACKGROUND & AIMS: Alcoholic liver disease (ALD) is a major cause of morbidity and mortality worldwide. However, the cellular defense mechanisms underlying ALD are not well understood. Recent studies highlighted the involvement of chaperone mediated autophagy (CMA) in regulating hepatic lipid metabolism. Sorting nexin (SNX)-10 has a regulatory function in endolysosomal trafficking and stabilisation. Here, we investigated the roles of SNX10 in CMA activation and in the pathogenesis of alcohol-induced liver injury and steatosis. METHODS: Snx10 knockout (Snx10 KO) mice and their wild-type (WT) littermates fed either the Lieber-DeCarli liquid alcohol diet or a control liquid diet, and primary cultured WT and Snx10 KO hepatocytes stimulated with ethanol, were used as in vivo and in vitro ALD models, respectively. Activation of CMA, liver injury parameters, inflammatory cytokines, oxidative stress and lipid metabolism were measured. RESULTS: Compared with WT littermates, Snx10 KO mice exhibited a significant amelioration in ethanol-induced liver injury and hepatic steatosis. Both in vivo and in vitro studies showed that SNX10 deficiency upregulated lysosome-associated membrane protein type 2A (LAMP-2A) expression and CMA activation, which could be reversed by SNX10 overexpression in vitro. LAMP-2A interference confirmed that the upregulation of Nrf2 and AMPK signalling pathways induced by SNX10 deficiency relied on CMA activation. Pull-down assays revealed an interaction between SNX10 and cathepsin A (CTSA), a key enzyme involved in LAMP-2A degradation. Deficiency in SNX10 inhibited CTSA maturation and increased the stability of LAMP-2A, resulting in an increase in CMA activity. CONCLUSIONS: SNX10 controls CMA activity by mediating CTSA maturation, and, thus, has an essential role in alcohol-induced liver injury and steatosis. Our results provide evidence for SNX10 as a potential promising therapeutic target for preventing or ameliorating liver injury in ALD. LAY SUMMARY: Alcoholic liver disease is a major cause of morbidity and mortality worldwide. Recent studies highlight the involvement of chaperone-mediated autophagy (CMA) in regulating hepatic lipid metabolism. Our study reveals that deficiency of sorting nexin (SNX) 10 increases the stability of LAMP-2A by inhibiting cathepsin A maturation, resulting in the increase of CMA activity and, thus, alleviates alcohol-induced liver injury and steatosis. PMID- 29452207 TI - Glycogen synthase kinase 3beta promotes liver innate immune activation by restraining AMP-activated protein kinase activation. AB - BACKGROUND & AIMS: Glycogen synthase kinase 3beta (Gsk3beta [Gsk3b]) is a ubiquitously expressed kinase with distinctive functions in different types of cells. Although its roles in regulating innate immune activation and ischaemia and reperfusion injuries (IRIs) have been well documented, the underlying mechanisms remain ambiguous, in part because of the lack of cell-specific tools in vivo. METHODS: We created a myeloid-specific Gsk3b knockout (KO) strain to study the function of Gsk3beta in macrophages in a murine liver partial warm ischaemia model. RESULTS: Compared with controls, myeloid Gsk3b KO mice were protected from IRI, with diminished proinflammatory but enhanced anti inflammatory immune responses in livers. In bone marrow-derived macrophages, Gsk3beta deficiency resulted in an early reduction of Tnf gene transcription but sustained increase of Il10 gene transcription on Toll-like receptor 4 stimulation in vitro. These effects were associated with enhanced AMP-activated protein kinase (AMPK) activation, which led to an accelerated and higher level of induction of the novel innate immune negative regulator small heterodimer partner (SHP [Nr0b2]). The regulatory function of Gsk3beta on AMPK activation and SHP induction was confirmed in wild-type bone marrow-derived macrophages with a Gsk3 inhibitor. Furthermore, we found that this immune regulatory mechanism was independent of Gsk3beta Ser9 phosphorylation and the phosphoinositide 3-kinase Akt signalling pathway. In vivo, myeloid Gsk3beta deficiency facilitated SHP upregulation by ischaemia-reperfusion in liver macrophages. Treatment of Gsk3b KO mice with either AMPK inhibitor or SHP small interfering RNA before the onset of liver ischaemia restored liver proinflammatory immune activation and IRI in these otherwise protected hosts. Additionally, pharmacological activation of AMPK protected wild-type mice from liver IRI, with reduced proinflammatory immune activation. Inhibition of the AMPK-SHP pathway by liver ischaemia was demonstrated in tumour resection patients. CONCLUSIONS: Gsk3beta promotes innate proinflammatory immune activation by restraining AMPK activation. LAY SUMMARY: Glycogen synthase kinase 3beta promotes macrophage inflammatory activation by inhibiting the immune regulatory signalling of AMP-activated protein kinase and the induction of small heterodimer partner. Therefore, therapeutic targeting of glycogen synthase kinase 3beta enhances innate immune regulation and protects liver from ischaemia and reperfusion injury. PMID- 29452208 TI - Outcome of ABO-incompatible adult living-donor liver transplantation for patients with hepatocellular carcinoma. AB - BACKGROUND & AIMS: Living-donor liver transplantation (LDLT) can simultaneously cure hepatocellular carcinoma (HCC) and underlying liver cirrhosis, improving long-term results in patients with HCC. ABO-incompatible LDLT could expand the living-donor pool, reduce waiting times for deceased-donor liver transplantation, and improve long-term survival for some patients with HCC. METHODS: We retrospectively reviewed the medical records of patients undergoing LDLT for HCC from November 2008 to December 2015 at a single institution in Korea. In total, 165 patients underwent ABO-incompatible and 753 patients underwent ABO-compatible LDLT for HCC. ABO-incompatible recipients underwent desensitization to overcome the ABO blood group barrier, including pretransplant plasma exchange and rituximab administration (300-375 mg/m2 /body surface area). RESULTS: We performed 1:1 propensity score matching and included 165 patients in each group. 82.4% of ABO-incompatible and 83.0% of -compatible LDLT groups had HCC within conventional Milan criteria, respectively, and 92.1% and 92.7% of patients in each group had a Child-Pugh score of A or B. ABO-incompatible and -compatible LDLT groups were followed up for 48.0 and 48.7 months, respectively, with both groups showing comparable recurrence-free survival rates (hazard ratio [HR] 1.14; 95% CI 0.68-1.90; p = 0.630) and overall patient-survival outcomes (HR 1.10; 95% CI 0.60-2.00; p = 0.763). CONCLUSIONS: These findings suggested that ABO incompatible liver transplantation is a feasible option for patients with HCC, especially for those with compensated cirrhosis with HCC within conventional Milan criteria. LAY SUMMARY: Despite hypothetical immunological concerns that the desensitization protocol for breaking through the ABO blood group barrier might have a negative impact on the recurrence of hepatocellular carcinoma, our experience demonstrated no significant differences in the long-term overall survival and recurrence-free survival rates between patients receiving ABO compatible or ABO-incompatible liver transplantation. In conclusion, results from our institution indicated that ABO-incompatible living-donor liver transplantation constitutes a potentially feasible option for patients with hepatocellular carcinoma, especially those with compensated cirrhosis with hepatocellular carcinoma within conventional Milan criteria. PMID- 29452209 TI - Prolactin improves hepatic steatosis via CD36 pathway. AB - BACKGROUND & AIMS: Prolactin (PRL) is a multifunctional polypeptide with effects on metabolism, however, little is known about its effect on hepatic steatosis and lipid metabolism. Herein, we aimed to assess the role of PRL in the development of non-alcoholic fatty liver disease (NAFLD). METHODS: The serum PRL levels of 456 patients with NAFLD, 403 controls without NAFLD diagnosed by ultrasound, and 85 individuals with liver histology obtained during metabolic surgery (44 female and 30 male patients with NAFLD and 11 age-matched non-NAFLD female individuals) were evaluated. The expression of the gene encoding the prolactin receptor (PRLR) and signalling molecules involved in hepatic lipid metabolism were evaluated in human liver and HepG2 cells. The effects of overexpression of PRLR or fatty acid translocase (FAT)/CD36 or knockdown of PRLR on hepatic lipid metabolism were tested in free fatty acid (FFA)-treated HepG2 cells. RESULTS: Circulating PRL levels were lower in individuals with ultrasound-diagnosed NAFLD (men: 7.9 [range, 5.9-10.3] ug/L; women: 8.7 [range, 6.1-12.4] ug/L) than those with non NAFLD (men: 9.1 [range, 6.8-13.0] ug/L, p = 0.002; women: 11.6 [range, 8.2-16.1] ug/L, p <0.001). PRL levels in patients with biopsy-proven severe hepatic steatosis were lower compared with those with mild-to-moderate hepatic steatosis in both men (8.3 [range, 5.4-9.5] ug/L vs. 9.7 [range, 7.1-12.3] ug/L, p = 0.031) and women (8.5 [range, 4.2-10.6] ug/L vs. 9.8 [range, 8.2-15.7] ug/L, p = 0.027). Furthermore, hepatic PRLR gene expression was significantly reduced in patients with NAFLD and negatively correlated with CD36 gene expression. In FFA-induced HepG2 cells, PRL treatment or PRLR overexpression significantly reduced the expression of CD36 and lipid content, effects that were abrogated after silencing of PRLR. Furthermore, overexpression of CD36 significantly reduced the PRL mediated improvement in lipid content. CONCLUSIONS: Our results reveal a novel association between the central nervous system and the liver, whereby PRL/PRLR improved hepatic lipid accumulation via the CD36 pathway. LAY SUMMARY: Our clinical study suggests a negative association between prolactin (PRL)/prolactin receptor (PRLR) and the presence of non-alcoholic fatty liver disease (NAFLD). Using cell experiments, we found that PRL ameliorates hepatic steatosis via the hepatic PRLR and fatty acid translocase (FAT)/CD36, a key transporter of free fatty acid uptake in liver. Our findings suggest a novel approach to improving NAFLD using PRL and PRLR. Clinical trial number: NCT03296605. PMID- 29452210 TI - Computer simulations for bioequivalence trials: Selection of analyte in BCS class II and IV drugs with first-pass metabolism, two metabolic pathways and intestinal efflux transporter. AB - A semi-physiological two compartment pharmacokinetic model with two active metabolites (primary (PM) and secondary metabolites (SM)) with saturable and non saturable pre-systemic efflux transporter, intestinal and hepatic metabolism has been developed. The aim of this work is to explore in several scenarios which analyte (parent drug or any of the metabolites) is the most sensitive to changes in drug product performance (i.e. differences in in vivo dissolution) and to make recommendations based on the simulations outcome. A total of 128 scenarios (2 Biopharmaceutics Classification System (BCS) drug types, 2 levels of KM Pgp, in 4 metabolic scenarios at 2 dose levels in 4 quality levels of the drug product) were simulated for BCS class II and IV drugs. Monte Carlo simulations of all bioequivalence studies were performed in NONMEM 7.3. Results showed the parent drug (PD) was the most sensitive analyte for bioequivalence trials in all the studied scenarios. PM and SM revealed less or the same sensitivity to detect differences in pharmaceutical quality as the PD. Another relevant result is that mean point estimate of Cmax and AUC methodology from Monte Carlo simulations allows to select more accurately the most sensitive analyte compared to the criterion on the percentage of failed or successful BE studies, even for metabolites which frequently show greater variability than PD. PMID- 29452211 TI - Impact of change of matrix crystallinity and polymorphism on ovalbumin release from lipid-based implants. AB - The objectives of this study were to prepare lipid-based implants by hot melt extrusion (HME) for the prolonged release of ovalbumin (OVA), and to relate protein release to crystallinity and polymorphic changes of the lipid matrix. Two lipids, glycerol tristearate and hydrogenated palm oil, with different composition and degree of crystallinity were studied. Solid OVA was dispersed within the lipid matrixes, which preserved its stability during extrusion. This was partially attributed to a protective effect of the lipidic matrix. The incorporation of OVA decreased the mechanical strength of the implants prepared with the more crystalline matrix, glycerol tristearate, whereas it remained comparable for the hydrogenated palm oil because of stronger physical and non covalent interactions between the protein and this lipid. This was also the reason for the faster release of OVA from the glycerol tristearate matrix when compared to the hydrogenated palm oil (8 vs. 28 weeks). Curing induced and increased crystallinity, and changes in the release rate, especially for the more crystalline matrix. In this case, both an increase and a decrease in release, were observed depending on the tempering condition. Curing at higher temperatures induced a melt-mediated crystallization and solid state transformation of the glycerol tristearate matrix and led to rearrangements of the inner structure with the formation of larger pores, which accelerated the release. In contrast, changes in the hydrogenated palm oil under the same curing conditions were less noticeable leading to a more robust formulation, because of less polymorphic changes over time. This study helps to understand the effect of lipid matrix composition and crystallinity degree on the performance of protein-loaded implants, and to establish criteria for the selection of a lipid carrier depending on the release profile desired. PMID- 29452212 TI - Exploring in vivo metabolism and excretion of QO-58L using ultra-high-performance liquid chromatography coupled with tandem mass spectrometry. AB - QO-58 lysine (QO-58L) as a new potassium channel opener, reported to have a potential activity to cure neuropathic pain. The aim of this research is to develop and validate a high-performance liquid chromatography with tandem spectrometry (LC-MS/MS) method for the quantification of QO-58L in rat urine, feces and bile. In addition, analyze and identify the metabolites in urine and bile. The assay for this compound in samples detected with multiple reaction monitoring mode (MRM), and take nimodipine as internal standards (IS). To better understand the biotransformation of QO-58L, metabolites in urine and bile were identified by using ultra high performance liquid chromatography tandem quadrupole/time of flight mass spectrometry (UHPLC-Q-TOF-MS) in the positive and negative ion mode. Urine, feces and bile were quantified by three new methods. The results showed that: QO-58L was mainly eliminated through fecal route (92.94%), a small amount of it via biliary excretion (2.05%), and rarely through urinary excretion (0.024%). As a result, there are 11 metabolites were identified, including 8 phase I metabolites resulting from elimination, hydroxylation and dihydroxylation, and 3 phase II metabolites originating from sulfation, N-acetylcysteine conjugation and glucuronidation. Furthermore, the newly discoveries of excretion and metabolism significantly expanded our understanding and was going to be greatly helpful for QO-58L's further pharmacokinetic study in vivo. PMID- 29452213 TI - Nanoemulsion of atovaquone as a promising approach for treatment of acute and chronic toxoplasmosis. AB - Treatment of toxoplasmosis is necessary in congenital form and immunocompromised patients. Atovaquone is a powerful suppressor of protozoan parasites with a broad spectrum activity, but an extremely low water solubility and bioavailability. In this study, nanoemulsion of this drug was prepared with grape seed oil using spontaneous emulsification method to increase bioavailability and efficacy of atovaquone for treatment of toxoplasmosis. In vitro activity of atovaquone nanoemulsion against T. gondii, RH and Tehran strains, was assessed in HeLa cell culture. For in vivo assessment, BALB/c mice were infected with RH and Tehran strains and then treated with nanoemulsion of atovaquone, compared to that treated with free atovaquone. Concentration of atovaquone nanoemulsion showed in vitro anti-parasitic effects in both strains of T. gondii. Furthermore, oral administration of atovaquone nanoemulsion increased oral bioavailability, tissue distribution and mice survival time and reduced parasitemia and number and size of the brain cysts. Decrease of cyst numbers was verified by down regulation of BAG1 using real-time polymerase chain reaction (real-time PCR) assay. Effective therapeutic activity of atovaquone at a reduced dose is the major achievement of this study. PMID- 29452214 TI - Progranulin promotes lymphangiogenesis through VEGF-C and is an independent risk factor in human esophageal cancers. AB - Lymph node metastasis is one of the most important predictors of the prognosis for esophageal cancer (EC) patients. However, the mechanism underlying the lymph node metastasis is largely unknown. Progranulin (PGRN) is shown to be highly expressed in various types of cancers and could promote the angiogenesis and epithelial-mesenchymal transition of cancer cells in previous studies. However, the expression status of PGRN and its effects on the lymphangiogenesis in EC are largely unclear. In this study, we show for the first time that PGRN is expressed in EC tissue samples and cell lines and could promote the expression of VEGF-C in vitro, a well-known lymphangiogenesis inducer, through the putative signaling transducers p-ERK and p-AKT. Besides, increased levels of PGRN are correlated with lymph node metastasis, high levels of lymph microvessel density, and lymph vessel space invasion in tissue samples of EC patients. In addition, Cox proportional risk model shows that patients with high levels of PGRN would have 2 fold increases in 5-year mortality compared with patients with low levels of PGRN. Finally, we establish a clinically useful nomogram to predict the possibility of mortality for individual EC patients. In conclusion, PGRN may play an important role in the lymphangiogenesis through activation of VEGF-C in the EC patients. PMID- 29452215 TI - Lymphocytic colitis: pathologic predictors of response to therapy. AB - Although the presence of intraepithelial lymphocytosis with surface epithelial damage is a unifying feature of lymphocytic colitis, there are nonclassical features that create morphologic heterogeneity between cases. Limited data on the significance of these secondary histologic features are available. Cases of lymphocytic colitis diagnosed between 2002 and 2013 were identified using the Research Patient Data Registry of a tertiary referral center. Diagnostic biopsy slides were reviewed and evaluated for histologic features of lymphocytic colitis. Clinical data including type of therapy and response to treatment were collected. chi2 Test (or Fisher exact test) and logistic regression analysis were used where appropriate. Thirty-two cases of lymphocytic colitis with complete clinical data and slides available for review were identified. The mean age was 56.4 years, and the female-to-male ratio was 3:2. Eleven patients improved with minimal intervention (group 1), 14 patients responded to steroid therapy (group 2), and 7 patients responded to mesalamine, bismuth subsalicylate, and/or cholestyramine therapy (group 3). Histologic differences in the characteristics of the subepithelial collagen table (P = .018), the severity of lamina propria inflammation (P = .042), and the presence of eosinophil clusters (P = .016) were seen between groups 2 and 3. Patients in group 1 were more likely to have mild crypt architectural distortion in their biopsies than patients in groups 2 and 3. Lymphocytic colitis is a heterogeneous disease, and the evaluation of histologic factors may help identify various subtypes and predict therapy response. PMID- 29452216 TI - Upregulation of Tiam1 contributes to cervical cancer disease progression and indicates poor survival outcome. AB - T lymphoma invasion and metastasis 1 (Tiam1), a guanine nucleotide exchange factor, is involved in the tumorigenesis of a number of malignancies. This study was aimed to explore the role of Tiam1 in cervical cancer progression, and evaluate the prognostic values. Tiam1 protein expression levels were detected by immunohistochemical (IHC) staining in 174 cervical cancer tissues, 92 of CINs (cervical intraepithelial neoplasia) and 32 of normal cervical epithelia tissues. Clinicopathological parameters and overall survival data were collected and compared between different Tiam1 statuses. The role of Tiam1 in cervical cancer proliferation, migration and angiogenesis were detected using si-RNA (small interfering RNA) transfection. In results, Tiam1 protein showed a cytoplasmic and nuclear staining pattern in cervical cancer tissues. The strongly positive expression of Tiam1 protein was observed in 51.72% (90/174) of cervical cancers, which was significantly higher than in CINs and normal cervical epithelia tissues (9.38%, 3/32). High Tiam1 protein expression was closely associated with advanced clinical stage, differentiation, lymph node (LN) metastasis, HPV infection and lower overall survival (OS) rates in cervical cancer. Multivariate analysis indicated that Tiam1 was an independent prognostic factor, along with clinical stage, in patients with cervical cancer. Additionally, Tiam1 depletion by RNAi in cervical cancer cells significantly decreased cell proliferation, migration and angiogenesis. In conclusion, our study demonstrated that upregulation of Tiam1 contributes to cervical cancer disease progression and indicates poor survival outcome. PMID- 29452217 TI - Gene expression screening identifies CDCA5 as a potential therapeutic target in acral melanoma. AB - Acral melanoma (AM) is a rapidly progressing subtype of melanoma with poor prognosis. The complete array of molecular changes that occur during AM metastasis remains unclear. In this study, we compared the gene expression profiles of 6 primary and 12 lymph node metastatic AM samples by tissue microarray analysis. We found that the expression levels of 396 genes were increased and that of 766 genes were decreased in the metastatic tissues compared with that in the primary tumors. The top 19 genes upregulated in the metastatic tissue specimens were selected for high-content short interfering RNA screening. We found that inhibition of cell division cycle-associated 5 (CDCA5) significantly suppressed AM cell migration and invasion. Furthermore, we demonstrated that upregulation of CDCA5 was correlated with higher tumor-node metastases stages (P=.025) and a shorter disease-free survival in patients with AM (P=.038). Cox regression analyses showed that high CDCA5 expression was also an independent factor of disease-free survival for patients with AM (hazard ratio =1.86, P=.041). Overall, our data define the gene expression signature of AM metastasis and indicate that CDCA5 is a potential therapeutic target in AM. PMID- 29452219 TI - Increased CD4 counts, pain and depression are correlates of lower sleep quality in treated HIV positive patients with low baseline CD4 counts. AB - Poor sleep quality leads to increased immune activation and immune activation leads to worse sleep quality. South African HIV positive patients typically have delayed start of treatment, which has been associated with CD4+ effector T cells being more spontaneously activated in chronically treated patients. This cross sectional study investigated whether subjective sleep quality was associated with CD4+ T lymphocyte reconstitution in treated South African HIV+ patients. One hundred and thirty-nine treated HIV+ patients (109 F, age average (SD) = 43 (9)) were recruited from Chris Hani Baragwanath Academic Hospital in Soweto, Johannesburg, South Africa. Participants completed questionnaires evaluating their subjective sleep quality (Pittsburgh Sleep Quality Index), daytime sleepiness (Epworth sleepiness scale), pain, and depression severity (Beck Depression Inventory). Univariate and multivariate analyses were run to determine the correlates of sleep quality in this population. Patients had been on antiretroviral treatment for about 4 years and had increased their CD4 counts from a median at baseline of 82 to 467 cells/uL. They had overall poor sleep quality (average (SD) PSQI = 7.7 (+/-5), 61% reporting PSQI > 5, a marker of lower sleep quality), 41% had clinical depression (average (SD) BDI = 17 (+/-12)) and 55% reported pain. In two separate multivariate analyses, both the overall CD4 count increase from baseline (p = 0.0006) and higher current CD4 counts (p = 0.0007) were associated with worse sleep quality, when adjusting for depression severity (p < 0.001), daytime sleepiness (p = 0.01) and the presence of pain (p < 0.01). In this cohort of treated South African HIV positive patients, poor sleep quality was associated with higher current CD4 counts, when adjusting for depression severity, daytime sleepiness and pain. Further studies should investigate the temporal relationship between HIV-related poor sleep quality and underlying immune activation.

AB - Recovery from major depressive disorder is difficult, particularly in patients who are refractory to antidepressant treatments. To examine factors that regulate recovery, we developed a prolonged learned helplessness depression model in mice. After the induction of learned helplessness, mice were separated into groups that recovered or did not recover within 4 weeks. Comparisons were made between groups in hippocampal proteins, inflammatory cytokines, and blood brain barrier (BBB) permeability. Compared with mice that recovered and control mice, non-recovered mice displaying prolonged learned helplessness had greater hippocampal activation of glycogen synthase kinase-3 (GSK3), higher levels of tumor necrosis factor alpha (TNFalpha), interleukin-17A, and interleukin-23, increased permeability of the blood brain barrier (BBB), and lower levels of the BBB tight junction proteins occludin, ZO1, and claudin-5. Treatment with the GSK3 inhibitor TDZD-8 reduced inflammatory cytokine levels, increased tight junction protein levels, and reversed impaired recovery from learned helplessness, demonstrating that prolonged learned helplessness is reversible and is maintained by abnormally active GSK3. In non-recovered mice with prolonged learned helpless, stimulation of sphingosine 1-phosphate receptors by Fingolimod or administration of the TNFalpha inhibitor etanercept repaired the BBB and reversed impaired recovery from prolonged learned helplessness. Thus, disrupted BBB integrity mediated in part by TNFalpha contributes to blocking recovery from prolonged learned helplessness depression-like behavior. Overall, this report describes a new model of prolonged depression-like behavior and demonstrates that stress-induced GSK3 activation contributes to disruption of BBB integrity mediated by inflammation, particularly TNFalpha, which contributes to impaired recovery from prolonged learned helplessness. PMID- 29452220 TI - Methods for analyzing matched designs with double controls: excess risk is easily estimated and misinterpreted when evaluating traffic deaths. AB - OBJECTIVES: To demonstrate analytic approaches for matched studies where two controls are linked to each case and events are accumulating counts rather than binary outcomes. A secondary intent is to clarify the distinction between total risk and excess risk (unmatched vs. matched perspectives). STUDY DESIGN AND SETTING: We review past research testing whether elections can lead to increased traffic risks. The results are reinterpreted by analyzing both the total count of individuals in fatal crashes and the excess count of individuals in fatal crashes, each time accounting for the matched double controls. RESULTS: Overall, 1,546 individuals were in fatal crashes on the 10 election days (average = 155/d), and 2,593 individuals were in fatal crashes on the 20 control days (average = 130/d). Poisson regression of total counts yielded a relative risk of 1.19 (95% confidence interval: 1.12-1.27). Poisson regression of excess counts yielded a relative risk of 3.22 (95% confidence interval: 2.72-3.80). The discrepancy between analyses of total counts and excess counts replicated with alternative statistical models and was visualized in graphical displays. CONCLUSION: Available approaches provide methods for analyzing count data in matched designs with double controls and help clarify the distinction between increases in total risk and increases in excess risk. PMID- 29452221 TI - A scoping review and survey provides the rationale, perceptions, and preferences for the integration of randomized and nonrandomized studies in evidence syntheses and GRADE assessments. AB - OBJECTIVES: To review the literature and obtain preferences and perceptions from experts regarding the role of randomized studies (RSs) and nonrandomized studies (NRSs) in systematic reviews of intervention effects. STUDY DESIGN AND SETTING: Scoping review and survey of experts. Using levels of certainty developed by the Grading of Recommendations Assessment, Development and Evaluation (GRADE) working group, experts expressed their preferences about the use of RS and NRS in health syntheses. RESULTS: Of 189 respondents, 123 had the expertise required to answer the questionnaire; 116 provided their extent of agreement with approaches to use NRS with RS. Most respondents would include NRS when RS was unfeasible (83.6%) or unethical (71.5%) and a majority to maximize the body of evidence (66.3%), compare results in NRS and RS (53.5%) and to identify subgroups (51.7%). Sizable minorities would include NRS and RS to address the effect of randomization (29.5%) or because the question being addressed was a public-health intervention (36.5%). In summary of findings tables, most respondents would include both bodies of evidence-in two rows in the same table-when RS provided moderate, low, or very-low certainty evidence; even when RS provided high certainty evidence, a sizable minority (25%) would still present results from both bodies of evidence. Very few (3.6%) would, under realistic circumstances, pool RS and NRS results. CONCLUSIONS: Most experts would include both RS and NRS in the same review under a wide variety of circumstances, but almost all would present results of two bodies of evidence separately. PMID- 29452222 TI - Essential medicines availability is still suboptimal in many countries: a scoping review. AB - OBJECTIVES: To identify uses of WHO Model list of essential medicines (EMs) and summarize studies examining EM and national EM lists (NEMLs). STUDY DESIGN AND SETTING: In this scoping review, we searched PubMed, Scopus, WHO website and WHO Regional Databases for studies on NEMLs, reimbursement medicines lists, and WHO EML, with no date or language restrictions. RESULTS: Three thousand one hundred forty-four retrieved documents were independently screened by two reviewers; 100 full-text documents were analyzed; 37 contained data suitable for quantitative and qualitative analysis on EMs availability (11 documents), medicines for specific diseases (13 documents), and comparison of WHO EML and NEMLs (13 documents). From the latter, two documents analyzed the relevance of evidence from Cochrane systematic reviews for medicines that were on NEMLs but not on the WHO EML. EMs availability is still suboptimal in low-income countries. Availability of children formulations and EMs for specific diseases such as chronic, cancer, pain, and reproductive health is suboptimal even in middle income countries. CONCLUSION: WHO EML can be used as a basic set of medicines for different settings. More evidence is needed into how NEMLs can contribute to better availability of children formulations, pain, and cancer medicines in developing countries. PMID- 29452223 TI - GRADE Guidelines: 19. Assessing the certainty of evidence in the importance of outcomes or values and preferences-Risk of bias and indirectness. AB - OBJECTIVES: The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) working group defines patient values and preferences as the relative importance patients place on the main health outcomes. We provide GRADE guidance for assessing the risk of bias and indirectness domains for certainty of evidence about the relative importance of outcomes. STUDY DESIGN AND SETTING: We applied the GRADE domains to rate the certainty of evidence in the importance of outcomes to several systematic reviews, iteratively reviewed draft guidance and consulted GRADE members and other stakeholders for feedback. RESULTS: This is the first of two articles. A body of evidence addressing the importance of outcomes starts at "high certainty"; concerns with risk of bias, indirectness, inconsistency, imprecision, and publication bias lead to downgrading to moderate, low, or very low certainty. We propose subdomains of risk of bias as selection of the study population, missing data, the type of measurement instrument, and confounding; we have developed items for each subdomain. The population, intervention, comparison, and outcome elements associated with the evidence determine the degree of indirectness. CONCLUSION: This article provides guidance and examples for rating the risk of bias and indirectness for a body of evidence summarizing the importance of outcomes. PMID- 29452225 TI - Human dendritic cell immunodeficiencies. AB - The critical functions of dendritic cells (DCs) in immunity and tolerance have been demonstrated in many animal models but their non-redundant roles in humans are more difficult to probe. Human primary immunodeficiency (PID), resulting from single gene mutations, may result in DC deficiency or dysfunction. This relatively recent recognition illuminates the in vivo role of human DCs and the pathophysiology of the associated clinical syndromes. In this review, the development and function of DCs as established in murine models and human in vitro systems, discussed. This forms the basis of predicting the effects of DC deficiency in vivo and understanding the consequences of specific mutations on DC development and function. DC deficiency syndromes are associated with heterozygous GATA2 mutation, bi-allelic and heterozygous IRF8 mutation and heterozygous IKZF1 mutation. The intricate involvement of DCs in the balance between immunity and tolerance is leading to increased recognition of their involvement in a number of other immunodeficiencies and autoimmune conditions. Owing to the precise control of transcription factor gene expression by super enhancer elements, phenotypic anomalies are relatively commonly caused by heterozygous mutations. PMID- 29452224 TI - Methodological and reporting quality in laboratory studies of human eating behavior. AB - The methodological quality and reporting practices of laboratory studies of human eating behavior determine the validity and replicability of nutrition science. The aim of this research was to examine basic methodology and reporting practices in recent representative laboratory studies of human eating behavior. We examined laboratory studies of human eating behavior (N = 140 studies) published during 2016. Basic methodology (e.g., sample size, use of participant blinding) and reporting practices (e.g., information on participant characteristics) were assessed for each study. Some information relating to participant characteristics (e.g., age, gender) and study methodology (e.g., length of washout periods in within-subjects studies) were reported in the majority of studies. However, other aspects of study reporting, including participant eligibility criteria and how sample size was determined were frequently not reported. Studies often did not appear to standardize pre-test meal appetite or attempt to blind participants to study aims. The average sample size of studies was small (between-subjects design studies in particular) and the primary statistical analyses in a number of studies (24%) were reliant on very small sample sizes that would be likely to produce unreliable results. There are basic methodology and reporting practices in the laboratory study of human eating behavior that are sub-optimal and this is likely to be affecting the validity and replicability of research. Recommendations to address these issues are discussed. PMID- 29452226 TI - Quantitative Proteomic Analysis Reveals Synaptic Dysfunction in the Amygdala of Rats Susceptible to Chronic Mild Stress. AB - The amygdala plays a key role in the pathophysiology of depression, but the molecular mechanisms underlying amygdalar hyperactivity in depression remain unclear. In this study, we used a chronic mild stress (CMS) protocol to separate susceptible and insusceptible rat subgroups. Proteomes in the amygdalae were analyzed differentially across subgroups based on labeling with isobaric tags for relative and absolute quantitation (iTRAQ) combined with mass spectrometry. Of 2562 quantified proteins, 102 were differentially expressed. Several proteins that might be associated with the stress insusceptibility/susceptibility difference, including synapse-related proteins, were identified in the amygdala. Immunoblot analysis identified changes in VGluT1, NMDA GluN2A and GluN2B and AMPA GluA1 receptors, and PSD-95, suggesting that CMS perturbs glutamatergic transmission in the amygdala. Changes in these regulatory and structural proteins provide insight into the molecular mechanisms underlying the abnormal synaptic morphological and functional plasticity in the amygdalae of stress-susceptible rats. Interestingly, the expression level of CaMKIIbeta, potentially involved in regulation of glutamatergic transmission, was significantly increased in the susceptible group. Subsequent in vitro experimentation showed that overexpression of CaMKIIbeta increased the expression of PSD-95 and GluA1 in cultured hippocampal neurons. This result suggested that CaMKIIbeta functions upstream from PSD-95 and GluA1 to affect LTP-based postsynaptic functional plasticity in the amygdalae of susceptible rats. Therefore, amygdalar CaMKIIbeta is a potential antidepressant target. Collectively, our findings contribute to a better understanding of amygdalar synaptic plasticity in depression. PMID- 29452228 TI - A BACH2 Gene Variant Is Associated with Postoperative Recurrence of Crohn's Disease. AB - BACKGROUND: Crohn's disease often requires intestinal resection, which is not considered curative. Repeat surgical intervention is necessary in more than half of patients after their initial operation. Although many genetic loci are implicated in Crohn's disease, few have been associated with post-resection recurrence. STUDY DESIGN: A cohort of patients with Crohn's disease who underwent intestinal resection was analyzed to determine genetic and clinical factors associated with post-resection recurrence. Genotype was assessed at 8 loci associated with adaptive immunity (SMAD3, IL10RB, IL15RA, BACH2, IL12B, IL18RAP, IFNGR2, and JAK2). Univariate and multivariable survival analyses were performed using a log-rank test and Cox-proportional hazard model, respectively. RESULTS: One hundred and ninety-one patients with Crohn's disease and 11.2 years mean postoperative follow-up were included. Forty-six percent experienced a surgical recurrence. Factors associated with increased incidence of recurrence included male sex (p = 0.05) and shortened time to first intestinal operation (5.0 vs 7.3 years; p = 0.03); inflammatory disease behavior was associated with a lower chance of repeat operation (p < 0.01). Of the loci assessed on multivariable analysis, homozygosity for a risk allele at BACH2 (rs1847472) was significantly associated with disease recurrence (hazard ratio 1.54; 95% CI 1.00 to 2.36; p < 0.05). CONCLUSIONS: We identify BACH2 as a susceptibility locus for postoperative recurrence of Crohn's disease in our cohort. BACH2 is critical in the differentiation and function of T cells, as a regulator of B-cell activity, and is associated with several dysregulated immunologic phenomena. Its identification as a risk locus in postoperative Crohn's disease recurrence suggests a potential role for regulatory T cells, effector T cells, humoral immunity, and immunologic memory in the development of this disease process. PMID- 29452227 TI - Age and experience dependent changes in Egr-1 expression during the ontogeny of the context preexposure facilitation effect (CPFE). AB - The context preexposure facilitation effect (CPFE) is a variant of contextual fear conditioning in which acquisition of the contextual representation and association of the retrieved contextual memory with an immediate foot-shock are separated by 24 h. During the CPFE, learning- related expression patterns of the early growth response-1 gene (Egr-1) vary based on training phase and brain sub region in adult and adolescent rats (Asok, Schreiber, Jablonski, Rosen, & Stanton, 2013; Schreiber, Asok, Jablonski, Rosen, & Stanton, 2014; Chakraborty, Asok, Stanton, & Rosen, 2016). The current experiments extended our previous findings by examining Egr-1 expression in infant (PD17) and juvenile (PD24) rats during the CPFE using preexposure protocols involving single-exposure (SE) or multiple-exposure (ME) to context. Following a 5 min preexposure to the training context (i.e. the SE protocol), Egr-1 expression in the medial prefrontal cortex (mPFC), dorsal hippocampus (dHPC) and lateral nucleus of the amygdala (LA) was differentially increased in PD24 rats relative to PD17 rats. In contrast, increased Egr-1 expression following an immediate foot-shock (2s, 1.5 mA) did not differ between PD17 and PD24 rats, and was not learning-related. Interestingly, increasing the number of exposures to the training chamber on the preexposure day (i.e. ME protocol) altered training-day expression such that a learning-related increase in expression was observed in the mPFC in PD24 but not PD17 rats. Together, these results illustrate a clear maturation of Egr-1 expression that is both age- and experience-dependent. In addition, the data suggest that regional activity and plasticity within the mPFC on the preexposure but not the training day may contribute to the ontogenetic profile of the effect. Further studies are necessary to elucidate the causal role of sub-region-specific neuroplasticity in the ontogeny of the CPFE.

PMID- 29452230 TI - A regulatory circuitry between miR-193a/miR-600 and WT1 enhances leukemogenesis in acute myeloid leukemia. AB - The aberrant overexpression of Wilms tumor-1 (WT1) in acute myeloid leukemia (AML) plays an important role in blast cell survival by enhancing proliferation and inhibiting apoptosis. However, the mechanism underlying the overexpression of WT1 remains unclear. Here, we identified miR-193a (miR-193a-5p) and miR-600 targeting and degrading WT1. MiR-193a and miR-600 synergistically reduced WT1 expression and suppressed the activity of a luciferase reporter by binding coding sequence and the 3'-untranslated region of WT1 mRNA, respectively. Furthermore, the expression of miR-193a and miR-600 was decreased in AML patients compared with normal controls. DNA hypermethylation in pre-miR-193a promoter, but not pre miR-600 promoter, caused the downregulation of miR-193a. Most intriguingly, ectopic expression of WT1 inhibited miR-600 expression, in turn, by binding the putative pre-miR-600 promoter, leading to the downregulation of miR-600 in AML blasts. Ectopic expression of miR-193a and miR-600 synergistically inhibited cell proliferation, induced apoptosis, and decreased colony formation in leukemia cells. Finally, overexpression of miR-193a and miR-600 decreased the growth of K562-inoculated tumor xenografts and extended survival time in THP1-transplanted leukemia mice. In conclusion, these data reveal an important role of miRNAs-WT1 circuitry in leukemia cells and the therapeutic promise of restoring miR-193a and miR-600 expression in AML patients. PMID- 29452231 TI - The association of 22 Y chromosome short tandem repeat loci with initiative aggressive behavior. AB - Aggressive behavior represents an important public concern and a clinical challenge to behaviorists and psychiatrists. Aggression in humans is known to have an important genetic basis, so to investigate the association of Y chromosome short tandem repeat (Y-STR) loci with initiative-aggressive behavior, we compared allelic and haplotypic distributions of 22 Y-STRs in a group of Chinese males convicted of premeditated extremely violent crimes (n = 271) with a normal control group (n = 492). Allelic distributions of DYS533 and DYS437 loci differed significantly between the two groups (P < 0.05). The case group had higher frequencies of DYS533 allele 14, DYS437 allele 14, and haplotypes 11-14 of DYS533-DYS437 compared with the control group. Additionally, the DYS437 allele 15 frequency was significantly lower in cases than controls. No frequency differences were observed in the other 20 Y-STR loci between these two groups. Our results indicate a genetic role for Y-STR loci in the development of initiative aggression in non-psychiatric subjects. PMID- 29452232 TI - Long noncoding RNA PVT1 promotes EMT via mediating microRNA-186 targeting of Twist1 in prostate cancer. AB - The pathogenesis and the underlying mechanism of endothelial-mesenchymal transition in prostate cancer remain unclear. Plasmacytoma variant translocation 1 (PVT1), a novel long non-coding RNA maps to 8q24.21, and in many tumor studies the up-regulation of PVT1 has already been reported. PVT1 is closely related to tumor cell proliferation, invasion, and metastasis. In this study, we employed a combination of techniques to study the role of PVT1 in prostate cancer, which included bioinformatic analysis, Western blotting and cell migration assays of prostate cancer cell lines. We report that PVT1 promotes prostate cancer invasion and metastasis by modulating EMT. Furthermore, PVT1 can promote EMT by up regulation of Twist1, a transcription factor associated with EMT. We then confirmed that PVT1 acts as a sponge for miRNA-186-5p and positively regulates Twist1 by a sponge effect. Therefore, this study has revealed a novel MECHANISM for the promotion of EMT in prostate cancer by PVT1. Our findings suggest that the PVT1/miR-186/Twist1 regulatory axis may be a new therapeutic target for prostate cancer. PMID- 29452233 TI - Role of adipose tissue derived stem cells differentiated into insulin producing cells in the treatment of type I diabetes mellitus. AB - Generation of new beta cells is an important approach in the treatment of type 1 diabetes mellitus (type 1 DM). Adipose tissue-derived stem cells (ADSCs) might be one of the best sources for cell replacement therapy for diabetes. Therefore, this work aimed to test the possible role of transplanted insulin-producing cells (IPCs) differentiated from ADSCs in treatment of streptozotocin (STZ) induced type I DM in rats. Type 1 DM was induced by single intra peritoneal injection with STZ (50 mg/kg BW). Half of the diabetic rats were left without treatment and the other half were injected with differentiated IPCs directly into the pancreas. ADSCs were harvested, cultured and identified by testing their phenotypes through flow cytometry. They were further subjected to differentiation into IPCs using differentiation medium. mRNA expression of pancreatic transcription factors (pdx1), insulin and glucose transporter-2 genes by real time PCR was done to detect the cellular differentiation and confirmed by stimulated insulin secretion. The pancreatic tissues from all groups were examined 2 months after IPC transplantation and were subjected to histological, Immunohistochemical and morphometric study. The differentiated IPCs showed significant expression of pancreatic beta cell markers and insulin secretion in glucose dependent manner. Treatment with IPCs induced apparent regeneration, diffused proliferated islet cells and significant increase in C-peptide immune reaction. We concluded that transplantation of differentiated IPCs improved function and morphology of Islet cells in diabetic rats. Consequently, this therapy option may be a promising therapeutic approach to patient with type 1 DM if proven to be effective and safe. PMID- 29452234 TI - Exploring the deleterious SNPs in XRCC4 gene using computational approach and studying their association with breast cancer in the population of West India. AB - Non-homologous end joining (NHEJ) pathway has pivotal role in repair of double strand DNA breaks that may lead to carcinogenesis. XRCC4 is one of the essential proteins of this pathway and single-nucleotide polymorphisms (SNPs) of this gene are reported to be associated with cancer risks. In our study, we first used computational approaches to predict the damaging variants of XRCC4 gene. Tools predicted rs79561451 (S110P) nsSNP as the most deleterious SNP. Along with this SNP, we analysed other two SNPs (rs3734091 and rs6869366) to study their association with breast cancer in population of West India. Variant rs3734091 was found to be significantly associated with breast cancer while rs6869366 variant did not show any association. These SNPs may influence the susceptibility of individuals to breast cancer in this population. PMID- 29452235 TI - Improved strength of silk fibers in Bombyx mori trimolters induced by an anti juvenile hormone compound. AB - BACKGROUND: Bombyx mori silk fibers with thin diameters have advantages of lightness and crease-resistance. Many studies have used anti-juvenile hormones to induce trimolters in order to generate thin silk; however, there has been comparatively little analysis of the morphology, structure and mechanical properties of trimolter silk. METHODS: This study induced two kinds of trimolters by appling topically anti-juvenile hormones and obtained thin diameter silk. Scanning electron microscope (SEM), FTIR analysis, tensile mechanical testing, chitin staining were used to reveal that the morphology, conformation and mechanical property of the trimolter silk. RESULTS: Cocoon of trimolters were highly densely packed by thinner fibers and thus had small apertures. We found that the conformation of trimolter silk fibroin changed and formed more beta sheet structures. In addition, analysis of mechanical parameters yielded a higher Young's modulus and strength in trimolter silk than in the control. By chitin staining of silk gland, we postulated that the mechanical properties of trimolters' silk was enhanced greatly during to the structural changes of silk gland. CONCLUSION: We induced trimolters by anti-juvenile hormones and the resulting cocoons were more closely packed and had smaller silk fiber diameters. We found that the conformation of trimolters silk fibroin had a higher content of beta-sheet structures and better mechanical properties. GENERAL SIGNIFICANCE: Our study revealed the structures and mechanical properties of trimolter silk, and provided a valuable reference to improve silk quality by influencing molting in silkworms. PMID- 29452236 TI - Cardiac and placental mitochondrial characterization in a rabbit model of intrauterine growth restriction. AB - BACKGROUND: Intrauterine growth restriction (IUGR) is associated with cardiovascular remodeling persisting into adulthood. Mitochondrial bioenergetics, essential for embryonic development and cardiovascular function, are regulated by nuclear effectors as sirtuins. A rabbit model of IUGR and cardiovascular remodeling was generated, in which heart mitochondrial alterations were observed by microscopic and transcriptomic analysis. We aimed to evaluate if such alterations are translated at a functional mitochondrial level to establish the etiopathology and potential therapeutic targets for this obstetric complication. METHODS: Hearts and placentas from 16 IUGR-offspring and 14 controls were included to characterize mitochondrial function. RESULTS: Enzymatic activities of complexes II, IV and II + III in IUGR-hearts (-11.96 +/- 3.16%; -15.58 +/- 5.32%; -14.73 +/- 4.37%; p < 0.05) and II and II + III in IUGR-placentas (-17.22 +/- 3.46%; p < 0.005 and -29.64 +/- 4.43%; p < 0.001) significantly decreased. This was accompanied by a not significant reduction in CI-stimulated oxygen consumption and significantly decreased complex II SDHB subunit expression in placenta (-44.12 +/- 5.88%; p < 0.001). Levels of mitochondrial content, Coenzyme Q and cellular ATP were conserved. Lipid peroxidation significantly decreased in IUGR-hearts (-39.02 +/- 4.35%; p < 0.001), but not significantly increased in IUGR-placentas. Sirtuin3 protein expression significantly increased in IUGR hearts (84.21 +/- 31.58%; p < 0.05) despite conserved anti-oxidant SOD2 protein expression and activity in both tissues. CONCLUSIONS: IUGR is associated with cardiac and placental mitochondrial CII dysfunction. Up-regulated expression of Sirtuin3 may explain attenuation of cardiac oxidative damage and preserved ATP levels under CII deficiency. GENERAL SIGNIFICANCE: These findings may allow the design of dietary interventions to modulate Sirtuin3 expression and consequent regulation of mitochondrial imbalance associated with IUGR and derived cardiovascular remodeling. PMID- 29452237 TI - A redox-sensitive signaling pathway mediates pro-angiogenic effect of chlordecone via estrogen receptor activation. AB - AIM: Chlordecone is able to induce pro-angiogenic effect through an estrogen receptor (ERalpha) pathway involving NO release and VEGF. The present study aimed to determine the molecular mechanisms by which chlordecone promotes angiogenesis in human endothelial cells. RESULTS: High but not low concentration of chlordecone increased mitochondrial respiratory capacity and mitochondrial DNA content in endothelial cells. The ROS scavenger MnTMPyP was able to prevent the increase of both VEGF expression and capillary length induced by chlordecone. A significant increase of cytoplasmic O2- production was observed after 1 and 4 h incubation of chlordecone, but not after 2 h. The NADPH oxidase inhibitor apocynin or silencing p47phox prevented angiogenesis and tube formation but also the increase in production of O2- at 1 h. In addition, apocynin as well silencing p47phox prevented eNOS activation and the NO synthase inhibitor L-NAME inhibited mitochondrial O2-production. All the previous effects of chlordecone were prevented by fulvestrant. CONCLUSION: Our results indicate that an adaptation of the mitochondrial energy metabolism occurs in the chlordecone angiogenic response. Finally, we showed that chlordecone induces endothelial cells angiogenesis by a cross-talk involving NADPH oxidase and mitochondrial O2-via a NO sensitive pathways through activation of ERalpha. These findings propose that a molecular mechanism may partly explain the epidemiological evidence implicating chlordecone as risk factor carcinogenesis. PMID- 29452239 TI - Letter to the editor. PMID- 29452238 TI - Human adipose tissue-derived stromal cells in combination with exogenous stimuli facilitate three-dimensional network formation of human endothelial cells derived from various sources. AB - In natural tissues, the nutrition of cells and removal of waste products is facilitated by a dense capillary network which is generated during development. This perfusion system is also indispensable for tissue formation in vitro. Nutrition depending solely on diffusion is not sufficient to generate tissues of clinically relevant dimensions, which is a core aim in tissue engineering research. In this study, the establishment of a vascular network was investigated in a self-assembling approach employing endothelial and mural cells. The process of vascularization was analyzed in constructs based on a carrier matrix of decellularized porcine small intestinal submucosa (SIS). A three-dimensional hydrogel containing MatrigelTM, collagen, and respective cells was casted on top of the SIS. Various types of human endothelial cells (hECs), e.g. HUVECs, cardiac tissue ECs (hCECs), pulmonary artery ECs (hPAECs), and iPSC-derived ECs, were co cultured with human adipose tissue-derived stromal cells (hASCs) within the hydrogel. Analyzed hECs were able to self-assemble and form three-dimensional networks harboring small caliber lumens within the hydrogel constructs in the presence of hASCs as supporting cells. Additionally, microvessel assembling required exogenous growth factor supplementation. This study demonstrates the development of stable vascularized hydrogels applying hASCs as mural cells in combination with various types of hECs, paving the way for the generation of clinically applicable tissue engineered constructs. PMID- 29452240 TI - The effect of non-TNF-targeted biologics and small molecules on insulin resistance in inflammatory arthritis. AB - Inflammatory arthritides are chronic diseases characterised by an increase in cardiovascular risk, largely attributable to the synergy between high-grade systemic inflammation and an elevated prevalence of traditional cardiovascular risk factors. Amongst the latter, insulin resistance and type 2 diabetes (T2D) play a key position. Previous studies demonstrated a potential insulin sensitizing effect of anti-TNF biologic medications. For converse, less is known about the role of newer biologics or small molecules. For this reason, we performed a systematic review of the literature in order to identify the available data on the effect on insulin resistance of non-TNF targeting biologics and small molecules approved for the treatment of inflammatory arthritides. The search strategy initially retrieved 486 records of which only 10 articles were selected for inclusion in the final review. According to the available evidence, some of the newest molecules, in particular tocilizumab and abatacept, may have a role in improving insulin sensitivity; for converse, anakinra-mediated effect on glucose metabolism may exploit different facets of T2D pathophysiology, such as the preservation of beta-cell function. However, the data available on this issue are largely inconsistent and future, adequately designed studies are still needed to clarify the differential impact of novel therapeutics on individual pathophysiological features of T2D and other emerging cardiovascular risk factors. PMID- 29452241 TI - Raw material variability of an active pharmaceutical ingredient and its relevance for processability in secondary continuous pharmaceutical manufacturing. AB - Active Pharmaceutical Ingredients (API) raw material variability is not always thoroughly considered during pharmaceutical process development, mainly due to low quantities of drug substance available. However, synthesis, crystallization routes and production sites evolve during product development and product life cycle leading to changes in physical material attributes which can potentially affect their processability. Recent literature highlights the need for a global approach to understand the link between material synthesis, material variability, process and product quality. The study described in this article aims at explaining the raw material variability of an API using extensive material characterization on a restricted number of representative batches using multivariate data analysis. It is part of a larger investigation trying to link the API drug substance manufacturing process, the resulting physical API raw material attributes and the drug product continuous manufacturing process. Eight API batches produced using different synthetic routes, crystallization, drying, delumping processes and processing equipment were characterized, extensively. Seventeen properties from seven characterization techniques were retained for further analysis using Principal Component Analysis (PCA). Three principal components (PCs) were sufficient to explain 92.9% of the API raw material variability. The first PC was related to crystal length, agglomerate size and fraction, flowability and electrostatic charging. The second PC was driven by the span of the particle size distribution and the agglomerates strength. The third PC was related to surface energy. Additionally, the PCA allowed to summarize the API batch-to-batch variability in only three PCs which can be used in future drug product development studies to quantitatively evaluate the impact of the API raw material variability upon the drug product process. The approach described in this article could be applied to any other compound which is prone to batch-to batch variability. PMID- 29452242 TI - Monolithic zirconia crowns in the aesthetic zone in heavy grinders with severe tooth wear - An observational case-series. AB - OBJECTIVES: The aim of this study was to assess the clinical outcomes and patient satisfaction with monolithic zirconia crowns in patients with severe tooth wear (>=1/3 of the tooth crown) in the aesthetic zone. METHODS: The historical prospective study sample consisted of 13 patients previously treated with a total of 84 monolithic zirconia crowns. The patients had been treated in a private clinic in Bergen, Norway, in the period 2012 to 2014. All patients were men, aged 35-67 years (mean age 56.3 years) and had been in need of prosthetic rehabilitation because of severe tooth wear in the aesthetic zone. Technical complications as well as biologic findings were registered when the crowns had been in function one to three years (mean 20 months). The patients completed a self-administered questionnaire regarding satisfaction with aesthetic and function. RESULTS: No biological complications were registered in 79 of the crowns (94%), and technical complications were registered in only two patients. All patients were satisfied with the aesthetic and function of the monolithic zirconia crowns and would choose the same treatment modality if they were to be treated again. CONCLUSIONS: Within the limitations of this study, we conclude that the rate of clinical complications was low and that the patients were satisfied with the aesthetic as well as the function of the monolithic zirconia crowns. CLINICAL SIGNIFICANCE: Monolithic zirconia crowns may provide a valid treatment modality in the aesthetic zone in patients with severe tooth wear.

AB - Removal of bacteria by handwashing with ozonated water was evaluated using the ASTM E1174 standard test method. Thirty healthy volunteers were assigned randomly to three groups: ozonated water, antimicrobial soap and water, and non antimicrobial soap and water. A 3 log10 cfu reduction was achieved by washing hands with ozonated water or antimicrobial soap and water. However, ozonated water was not significantly superior to non-antimicrobial soap and water. Ozonated water may remove bacteria from the hands to at least a similar extent as that by non-antimicrobial soap and water in the absence of visible dirt or body fluid contamination. PMID- 29452244 TI - Does saline enema during the first stage of labour reduce the incidence of Clostridium difficile colonization in neonates? A randomized controlled trial. AB - BACKGROUND: Maternal rectal enemas may reduce neonatal bacterial exposure during labour, which may reduce the risk of neonatal colonization with Clostridium difficile. The aim of this study was to determine the effectiveness of a saline enema during the first stage of labour in reducing neonatal colonization with C. difficile. METHODS: This study was conducted at Cairo University Hospital, Egypt from January 2016 to July 2016. Asymptomatic mothers with uncomplicated vaginal delivery and their neonates without diarrhoea were included. The study group underwent saline enema, and the control group had no intervention. Stool samples were collected from neonates one week after delivery. The primary outcome was the detection of C. difficile in stool culture and direct detection of C. difficile Toxin A and Toxin B by enzyme-linked immunosorbent assay. FINDINGS: The two groups were comparable (P>0.05) in terms of age, gravidity, parity, body mass index and gestational age. C. difficile was detected in 13.54% and 37.63% of stool cultures from the enema group and the control group, respectively (P<0.001). Direct detection of Toxins A and B was positive in 22.92% of cases in the enema group and 53.76% of cases in the control group (P<0.001). CONCLUSION: This study suggests that a saline enema for the mother during the first stage of labour may be useful in reducing the risk of neonatal gut colonization by C. difficile.

AB - Outcomes of nonmyeloablative (NMA) haploidentical (haplo) blood or marrow transplant (BMT) with post-transplantation cyclophosphamide (PTCy) using non first-degree relatives are unknown. We evaluated 33 consecutive adult patients (median age, 56 years) with hematologic malignancies who underwent NMA haplo T cell-replete BMT with PTCy at Johns Hopkins using second- or third-degree related donors. Donors consisted of 10 nieces (30%), 9 nephews (27%), 7 first cousins (21%), 5 grandchildren (15%), and 2 uncles (6%). Thirty-one patients (94%) reached full donor chimerism by day 60. The estimated cumulative incidence (CuI) of grades II to IV acute graft-versus-host disease (aGVHD) at day 180 was 24% (90% confidence interval [CI], 9% to 38%). Only 1 patient experienced grades III to IV aGVHD. At 1 year the CuI of chronic GVHD was 10% (90% CI, 0% to 21%). The CuI of nonrelapse mortality at 1 year was 5% (90% CI, 0% to 14%). At 1 year the probability of relapse was 31% (90% CI, 12% to 49%), progression-free survival 64% (90% CI, 48% to 86%), and overall survival 95% (90% CI, 87% to 100%). The 1 year probability of GVHD-free, relapse-free survival was 57% (90% CI, 41% to 79%). NMA haplo BMT with PTCy from non-first-degree relatives is an acceptably safe and effective alternative donor platform, with results similar to those seen with first-degree relatives. PMID- 29452246 TI - BMP signaling-driven osteogenesis is critically dependent on Prdx-1 expression mediated maintenance of chondrocyte prehypetrophy. AB - During endochondral ossification, cartilage template is eventually replaced by bone. This process involves several well characterized, stereotypic, molecular and cellular changes in the cartilage primordia. These steps involve transition from resting to proliferative and then pre-hypertrophic to finally hypertrophic cartilage. BMP signaling is necessary and sufficient for osteogenesis. However, the specific step(s) of endochondral ossification in which BMP signaling plays an essential role is not yet known. In this study we have identified Prdx1, a known scavenger of ROS, to be expressed in pre-hypertrophic chondrocytes in a BMP signaling-dependent manner. We demonstrate that BMP signaling inhibition increases ROS levels in osteogenic cells. Further, Prdx1 regulates osteogenesis in vivo by helping maintenance of Ihh expressing pre-hypertrophic cells, in turn regulating these cells' transition into hypertrophy. Therefore, our data suggests that one of the key roles of BMP signaling in endochondral ossification is to maintain pre-hypertrophic state. PMID- 29452247 TI - Persistent candidemia despite appropriate fungal therapy: First case of Candida auris from the United Arab Emirates. AB - In this case, we report an elderly patient with multiple chronic conditions and prolonged intensive care unit (ICU) stays who had recurrent Candida auris (C. auris) in blood despite antifungal therapy. C. auris was misidentified using conventional automated identification system as Candida haemulonii resulting in delayed diagnosis. The isolate showed increasing minimum inhibitory concentrations (MICs) to different antifungal drugs and persisted in the patient's blood before the patient deceased. This is the first case of C. auris reported from the United Arab Emirates (UAE); laboratories should be aware of this Candida species and should confirm suspected cases since it is an emerging multi-drug resistant and health-care associated Candida. PMID- 29452248 TI - Mercaptopyruvate acts as endogenous vasodilator independently of 3 mercaptopyruvate sulfurtransferase activity. AB - Hydrogen sulfide (H2S) is produced by the action of cystathionine-beta-synthase (CBS), cystathionine-gamma-lyase (CSE) or 3-mercaptopyruvate sulfurtransferase (3 MST). 3-MST converts 3-mercaptopyruvate (MPT) to H2S and pyruvate. H2S is recognized as an endogenous gaseous mediator with multiple regulatory roles in mammalian cells and organisms. In the present study we demonstrate that MPT, the endogenous substrate of 3-MST, acts also as endogenous H2S donor. Colorimetric, amperometric and fluorescence based assays demonstrated that MPT releases H2S in vitro in an enzyme-independent manner. A functional study was performed on aortic rings harvested from C57BL/6 (WT) or 3-MST-knockout (3-MST-/-) mice with and without endothelium. MPT relaxed mouse aortic rings in endothelium-independent manner and at the same extent in both WT and 3-MST-/- mice. N5-(1-Iminoethyl)-l ornithine dihydrochloride (L-NIO, an inhibitor of endothelial nitric oxide synthase) as well as 1H-[1,2,4]oxadiazolo [4,3-a]quinoxalin-1-one (ODQ, a soluble guanylyl cyclase inhibitor) did not affect MPT relaxant action. Conversely, hemoglobin (as H2S scavenger), as well as glybenclamide (an ATP-dependent potassium channel blocker) markedly reduced MPT-induced relaxation. The functional data clearly confirmed a non enzymatic vascular effect of MPT. In conclusion, MPT acts also as an endogenous H2S donor and not only as 3-MST substrate. MPT could, thus, be further investigated as a means to increase H2S in conditions where H2S bioavailability is reduced such as hypertension, coronary artery disease, diabetes or urogenital tract disease. PMID- 29452249 TI - Expression and therapeutic implications of cyclin-dependent kinase 4 (CDK4) in osteosarcoma. AB - Overexpression and/or hyperactivation of cyclin-dependent kinase 4 (CDK4) has been found in many types of human cancers, and a CDK4 specific inhibitor, palbociclib, has been recently approved by the FDA for the treatment of breast cancer. However, the expression and the therapeutic potential of CDK4 in osteosarcoma remain unclear. In the present study, CDK4 was found to be highly expressed in human osteosarcoma tissues and cell lines as compared with normal human osteoblasts. Elevated CDK4 expression correlated with metastasis potential and poor prognosis in osteosarcoma patients as determined by immunohistochemical analysis in a human osteosarcoma tissue microarray (TMA). CDK4 inhibition by either palbociclib or specific small interference RNA (siRNA) exhibited dose dependent inhibition of osteosarcoma cell proliferation and growth, accompanied by suppression of the CDK4/6-cyclinD-Rb signaling pathway. Flow cytometry analysis showed that CDK4 knockdown arrested osteosarcoma cells in the G1 phase of the cell cycle and induced cell apoptosis. Furthermore, inhibition of CDK4 significantly decreased osteosarcoma cell migration in vitro determined by the wound healing assay. These data highlight that CDK4 may be a potential promising therapeutic target in the treatment of human osteosarcoma. PMID- 29452250 TI - Hepcidin protects grass carp (Ctenopharyngodon idellus) against Flavobacterium columnare infection via regulating iron distribution and immune gene expression. AB - Columnaris disease (CD) caused by Flavobacterium columnare (F. columnare) is lack of knowledge on effective treatment measures. Bacterial pathogens require iron as an essential nutrient to infect the host. While hepcidin acts as a master regulator in iron metabolism, its contribution to host defense is emerging as complex and multifaceted. In vitro, recombinant Ctenopharyngodon idellus (C. idellus) hepcidin (CiHep) and synthetic CiHep both showed the ability to increase the expression of hepcidin and ferritin in C. idellus kidney cells, especially the recombinant CiHep. In vivo, recombinant CiHep improved the survival rate of C. idellus challenged with F. columnare. In addition, the fish fed diet containing recombinant CiHep (group H-1) had a higher survival rate than other pretreatment groups. The study showed that recombinant CiHep regulated iron metabolism causing iron redistribution, decreasing serum iron levels and increasing iron accumulation in the hepatopancreas. Moreover, the expression of iron-related genes was upregulated in various degrees at a different time except for group H-1. Immune-related genes were also evaluated, showing higher expression in the groups pretreated with CiHep at an early stage of infection. Of note, a clear upregulation of more immune genes occurred in the groups pretreated with recombinant CiHep than that pretreated with synthetic CiHep in the late stage of infection. In conclusion, the recombinant CiHep has a protective effect on the host response to bacterial pathogens. We speculate that hepcidin protects C. idellus against F. columnare infection via regulating the iron distribution and immune gene expression. PMID- 29452252 TI - Compared to what? The placebo effect in dry eye therapy. PMID- 29452251 TI - Using in vitro derived enzymatic reaction rates of metabolism to inform pesticide body burdens in amphibians. AB - Understanding how pesticide exposure to non-target species influences toxicity is necessary to accurately assess the ecological risks these compounds pose. To assess the potential metabolic activation of broad use pesticides in amphibians, in vitro and in vivo metabolic rate constants were derived from toad (Anaxyrus terrestris) livers in experiments measuring the depletion of atrazine (ATZ), triadimefon (TDN), and fipronil (FIP) as well as formation of their metabolites. To determine the predictability of these in vitro derived rate constants, Fowler's toads (Anaxyrus fowleri) were exposed to soil contaminated with each of the pesticides at maximum application rate. Desethyl atrazine (DEA) and deisopropyl atrazine (DIA), both metabolites of ATZ, exhibited similar velocities (Vmax) while the KM constant for DIA was two times higher than DEA. TDN was metabolized into two diastereomers of triadimenol (TDL A and TDL B), where TDL B had a Vmax around two times higher than TDL A. The metabolite fipronil sulfone's Vmax and KM were 150 pmol min-1 mg-1 and 29 MUM, respectively. While intrinsic clearance rates for the pesticides ranged from 0.54 to 38.31 mL min-1 kg-1. Thus, gaining knowledge on differences in metabolism of pesticides within amphibians is important in estimating risk to these non-target species since the inherent toxicity of metabolites can differ from the parent compound. PMID- 29452253 TI - Remote limb ischemic postconditioning protects against cerebral ischemia reperfusion injury by activating AMPK-dependent autophagy. AB - Remote limb ischemic postconditioning (RIPoC) is a promising adjunct treatment for cerebral ischemia-reperfusion (IR) injury. However, the underlying mechanisms have not been fully elucidated yet. The present study aims to investigate potential involvement and regulatory mechanisms of autophagy in RIPoC treatment against cerebral IR injury in mice. Mice were subjected to 2 h middle cerebral artery occlusion (MCAO) then treated with vehicle, 3-methyladenine (3-MA, an autophagy inhibitor), or compound C (an AMPK inhibitor) at the onset of reperfusion. RIPoC was carried out by 3 cycles of 10-min occlusion-reperfusion of bilateral femoral artery at the beginning of the reperfusion. Infarct volume, neurological score, and brain water content of the mice were assessed after 12 h reperfusion. Autophagy markers, cell apoptosis markers, and AMPK pathway activity were also evaluated. Our results indicated that RIPoC treatment reduced neurological deficits, brain water content, and infarct volume after IR. Meanwhile, RIPoC was proved to induce autophagy and activate AMPK pathway. Furthermore, the RIPoC-induced autophagy and neuroprotection were abolished by 3 MA and partially blocked by compound C. In conclusion, the present study suggests that RIPoC attenuates cerebral IR injury by activating AMPK-dependent autophagy. PMID- 29452254 TI - Response to the question (Ref> No.: JN2017754). PMID- 29452255 TI - Radiofrequency ablation of premature ventricular contractions originating from uncommon sites of right ventricle. AB - Premature Ventricular Contraction (PVC)/ventricular tachycardia (VT) with left bundle branch block (LBBB) morphology and inferior axis has been described classically to originate from the right ventricular outflow tract (RVOT). Some uncommon sites of idiopathic ventricular arrhythmia (VA) origins have been revealed including tricuspid annulus (TA) and right ventricular (RV) inflow free wall region. We present a series of two cases who have undergone electrophysiological study and successful radiofrequency ablation of frequent monomorphic PVCs with LBBB pattern originating from relatively uncommon sites of RV - TA and RV inflow free wall region. PMID- 29452256 TI - Modulation of oxidative stress response by flaxseed oil: Role of lipid peroxidation and underlying mechanisms. AB - Polyunsaturated fatty acids (PUFA's) are majorly classified as omega-3 and omega 6 fatty acids. The eicosapentaenoic acid (EPA, omega-3:20-5), docosahexaenoic acid (DHA, omega-3:22-6) and alpha-linolenic acid (ALA, omega-3:18-3) are known omega-3 fatty acids, extracted from animal (e.g fish oil) and plant sources (e.g flaxseed oil). Furthermore, linoleic acid (LA, omega-6:18-2) is recognized as omega-6 fatty acid and the most prominent biological fatty acid with a pro inflammatory response. Flaxseed oil has variety of biological roles, due to the significant amount of omega-3/omega-6 fatty acids. Numerous studies have reported that ALA (omega-3:18-3) and LA (omega-6:18-2) has diverse pharmacological activities. The ALA (omega-3:18-3) and LA (omega-6:18-2) are recognised to be the pharmacological antagonist. For example, ALA (omega-3:18-3) is recognised as anti inflammatory, whereas LA (omega-6:18-2) is considered to be pro-inflammatory. PUFA's get oxidized in three ways; firstly, free radical-mediated pathway, secondly non-free radical non-enzymatic metabolism, and lastly enzymatic degradation. The present report is an attempt to summarize various modes of PUFA's metabolism and elaborate biological effects of the associated metabolites concerning flaxseed oil.

AB - What are the new approaches and emerging ideas to prevent leptospirosis, a neglected bacterial re-emerging zoonotic disease? How do Leptospira interrogans escape the host defenses? We aim here to review and discuss the most recent literature that provides some answers to these questions, in particular data related to a better understanding of adaptive and innate immunity towards leptospires, and design of vaccines. This is an opinion paper, not a comprehensive review. We will try to highlight the new strategies and technologies boosting the search for drugs and vaccines. We will also address the bottlenecks and difficulties impairing the search for efficient vaccines and the many gaps in our knowledge of immunity against leptospirosis. Finally, we aim to delineate how Leptospira spp. escape the innate immune responses of Toll-Like receptors (TLR) and Nod-Like receptors (NLR). The rational use of TLR and NLR agonists as adjuvants could be key to design future vaccines against pathogenic leptospires. PMID- 29452259 TI - Real-world evaluation of a mobile health application in children with asthma. AB - BACKGROUND: Mobile health applications for asthma are increasingly being developed. However, there are no published randomized controlled trials evaluating efficacy in decreasing exacerbations. OBJECTIVE: To evaluate the impact of a mobile asthma application for asthma-related urgent health care usage. METHODS: We conducted a 6-month prospective randomized controlled trial for patients (6 months-21 years old) with persistent asthma presenting with an asthma exacerbation to the emergency department of a pediatric academic medical center. Participants were randomized to AsthmaCare (application providing medication and trigger reminders and treatment plan) or the control (online asthma information). Primary outcome measures were comparison of emergency department and urgent care visits and hospitalizations 6 months before and after randomization. RESULTS: AsthmaCare participants (n = 98) were slightly older (7.84 vs 6.24 years; P = .02) than controls (n = 95) but similar for sex (55% vs 62% boys), race (83% vs 77% African American), and insurer (89% vs 98% Medicaid). The 2 groups were similar in having more than 2 comorbidities (34% vs 32%) and receiving National Heart, Lung, and Blood Institute step 3 treatment or higher (69% vs 57%). There was no significant decrease in emergency department or urgent care visits or hospitalizations between the intervention and control groups. AsthmaCare participants were more likely to report improvement in asthma management 6 months after study enrollment (79% vs 64%; P = .06). CONCLUSION: This randomized controlled trial did not demonstrate a significant decrease in asthma-related emergency department visits or hospitalizations among children who used a mobile health application.

AB - As a feed additive, betaine is widely used in livestock production for its ability to promote growth. Our previous studies had reported that maternal betaine supplementation altered hepatic metabolism in offspring. But it remains unknown whether and how maternal betaine modulates metabolism of thyroid hormones in the offspring chickens by epigenetic modification. In this study, one hundred and twenty Rugao yellow-feathered laying hens were randomly divided into two groups, and were fed basal diet with or without 0.5% betaine supplementation for 28 days. After that, all the hens were artificially inseminated and then four hundreds fertilized eggs were selected. After hatching, the newborn chicks were raised until 56 days old. Betaine fed female chicks showed significantly lower body weight and lower level of biologically active thyroid hormone in plasma compared to control group, which was associated with significantly decrease in expression of type 1 iodothyronine deiodinase (Dio1). Moreover, betaine also changed hepatic expression of betaine-homocysteine -S-methyltransferase (BHMT) and DNA methyltransferase 1 (DNMT1), which may contribute to hypermethylation of the Dio1 promoter. Interestingly, betaine treatments of hens caused none of these effects in male chicks except Dio1 expression. These results indicate that maternal betaine administration effects growth of offspring through differential modification of Dio1 gene methylation and expression in liver and this model of transgenerational effects may help elucidate the mechanisms of maternal effects arise in natural systems.

PMID- 29452264 TI - Antagonists to TRPV1, ASICs and P2X have a potential role to prevent the triggering of regional bone metabolic disorder and pain-like behavior in tail suspended mice. AB - Our recent studies demonstrated that regional bone loss in the unloaded hind limbs of tail-suspended mice triggered pain-like behaviors due to the acidic environment in the bone induced by osteoclast activation. The aims of the present study were to examine whether TRPV1, ASIC and P2X (known as nociceptors) are expressed in bone, and whether the antagonists to those receptors affect the expression of osteoblast and osteoclast regulators, and prevent the triggering of not only pain-like behaviors but also high bone turnover conditions in tail suspension model mice. The hind limb-unloaded mice were subjected to tail suspension with the hind limbs elevated for 14days. The effects of the TRPV1, ASIC3, P2X2/3 antagonists on pain-like behaviors as assessed by the von Frey test, paw flick test and spontaneous pain scale; the expressions of TRPV1, ASICs, and P2X2 in the bone; and the effects of those antagonists on osteoblast and osteoclast regulators were examined. In addition, we evaluated the preventive effect of continuous treatment with a TRPV1 antagonist on the trigger for pain like behavior and bone loss in tail-suspended mice. Pain-like behaviors were significantly improved by the treatment with TRPV1, ASIC, P2X antagonists; TRPV1, ASICs and P2X were expressed in the bone tissues; and the antagonists to these receptors down-regulated the expression of osteoblast and osteoclast regulators in tail-suspended mice. In addition, continuous treatment with a TRPV1 antagonist during tail-suspension prevented the induction of pain-like behaviors and regional bone loss in the unloaded hind limbs. We, therefore, believe that those receptor antagonists have a potential role in preventing the triggering of skeletal pain with associated regional bone metabolic disorder. PMID- 29452265 TI - Characterizing the modulation of resting-state fMRI metrics by baseline physiology. AB - The blood-oxygenation level dependent (BOLD) functional magnetic resonance imaging (fMRI) signal is commonly used to assess functional connectivity across brain regions, particularly in the resting state (rs-fMRI). However, the BOLD fMRI signal is not merely a representation of neural activity, but a combination of neural activity and vascular response. These aspects of the BOLD signal are easily influenced by systemic physiology, potentially biasing BOLD-based functional connectivity measurements. In this work, we focus on the following physiological modulators of the BOLD signal: cerebral blood flow (CBF), venous blood oxygenation, and cerebrovascular reactivity (CVR). We use simulations and experiments to examine the relationship between the physiological parameters and rs-fMRI functional connectivity measurements in three resting-state networks: default mode network, somatosensory network and visual network. By using the general linear model, we demonstrate that physiological modulators significantly impact functional connectivity measurements in these regions, but in a manner that depends on the interplay between signal- and noise-driven correlations. Moreover, we find that the physiological effects vary by brain region and depend on the range of physiological conditions probed; the associations are more complex than previously reported. The results confirm that it is important to account for the effect of physiological modulators when comparing resting-state fMRI metrics. We note that such modulatory effects may be amplified by disease conditions, which will warrant future investigations. PMID- 29452266 TI - Healthy brain aging: Interplay between reactive species, inflammation and energy supply. AB - Brains' high energy expenditure with preferable utilization of glucose and ketone bodies, defines the specific features of its energy homeostasis. The extensive oxidative metabolism is accompanied by a concomitant generation of high amounts of reactive oxygen, nitrogen, and carbonyl species, which will be here collectively referred to as RONCS. Such metabolism in combination with high content of polyunsaturated fatty acids creates specific problems in maintaining brains' redox homeostasis. While the levels of products of interaction between RONCS and cellular components increase slowly during the first two trimesters of individuals' life, their increase is substantially accelerated towards the end of life. Here we review the main mechanisms controlling the redox homeostasis of the mammalian brain, their age-dependencies as well as their adaptive potential, which might turn out to be much higher than initially assumed. According to recent data, the organism seems to respond to the enhancement of aging-related toxicity by forming a new homeostatic set point. Therefore, further research will focus on understanding the properties of the new set point(s), the general nature of this phenomenon and will explore the limits of brains' adaptivity. PMID- 29452267 TI - GIT2-A keystone in ageing and age-related disease. AB - Since its discovery, G protein-coupled receptor kinase-interacting protein 2, GIT2, and its family member, GIT1, have received considerable interest concerning their potential key roles in regulating multiple inter-connected physiological and pathophysiological processes. GIT2 was first identified as a multifunctional protein that is recruited to G protein-coupled receptors (GPCRs) during the process of receptor internalization. Recent findings have demonstrated that perhaps one of the most important effects of GIT2 in physiology concerns its role in controlling multiple aspects of the complex ageing process. Ageing can be considered the most prevalent pathophysiological condition in humans, affecting all tissue systems and acting as a driving force for many common and intractable disorders. The ageing process involves a complex interplay among various deleterious activities that profoundly disrupt the body's ability to cope with damage, thus increasing susceptibility to pathophysiologies such as neurodegeneration, central obesity, osteoporosis, type 2 diabetes mellitus and atherosclerosis. The biological systems that control ageing appear to function as a series of interconnected complex networks. The inter-communication among multiple lower-complexity signaling systems within the global ageing networks is likely coordinated internally by keystones or hubs, which regulate responses to dynamic molecular events through protein-protein interactions with multiple distinct partners. Multiple lines of research have suggested that GIT2 may act as one of these network coordinators in the ageing process. Identifying and targeting keystones, such as GIT2, is thus an important approach in our understanding of, and eventual ability to, medically ameliorate or interdict age related progressive cellular and tissue damage. PMID- 29452268 TI - High Prevalence of Liver Fibrosis Among European Adults With Unknown Liver Disease: A Population-Based Study. AB - BACKGROUND & AIMS: Liver fibrosis is the main determinant of long-term outcome in chronic liver diseases. Little is known about the prevalence of liver fibrosis in the general population. The aim of the study was to investigate the prevalence of liver fibrosis in the general adult population with unknown liver disease. METHODS: This was a population-based, cross-sectional study performed in the Barcelona metropolitan area. Subjects aged 18 to 75 years old were identified randomly from citizens included in the primary health care registry. Of 4866 subjects invited, 3076 participated (63.2%). Liver fibrosis was estimated by measuring liver stiffness (LS) with transient elastography (TE). Liver histology was assessed in 92 subjects with increased LS. RESULTS: Prevalence estimates of increased LS (>=6.8, >=8.0, and >=9.0 kPa) were 9.0%, 5.8%, and 3.6%, respectively. The etiology of liver disease was mainly nonalcoholic fatty liver disease (NAFLD), followed by alcohol risk consumption (consumption of >=21 standard drinking units/wk in men and >=14 standard drinking units/wk in women). Factors independently associated with increased LS were male sex, abdominal obesity, type 2 diabetes, serum glucose, high-density lipoprotein, and triglyceride levels. Subjects without risk factors for NAFLD or without alcohol risk consumption had a very low prevalence of increased LS. The best cut-off value of LS for significant liver fibrosis (F2-F4) was 9.2 kPa, with high sensitivity and specificity. TE was more accurate than alanine aminotransferase, NAFLD fibrosis score, or Fibrosis 4. An algorithm for screening for liver fibrosis using TE in the community setting is proposed. CONCLUSIONS: These findings show a high prevalence of silent liver disease with advanced fibrosis mainly related to NAFLD in adult European subjects without known liver disease. An LS value less than 9.2 kPa predicts the absence of significant liver fibrosis with high accuracy and could be used for screening purposes.

PMID- 29452270 TI - High-level extracellular production of Rhizopus oryzae lipase in Pichia pastoris via a strategy combining optimization of gene-copy number with co-expression of ERAD-related proteins. AB - Rhizopus oryzae lipase (ROL) is an important industrial enzyme limited in application due to its low production in native strains. Here, we used a new combined strategy to overexpress ROL in Pichia pastoris. An efficient method based on bio-brick was developed to construct a series of vectors harboring different copy numbers of ROL gene cassettes, which were then transformed into P. pastoris GS115 to generate a strain with specific copy numbers of ROL. An optimized gene-dosage recombinant strain of GS115/pAOalpha-5ROL 11# harboring five copies of ROL was screened, revealing production of the highest activity (2700 U/mL), which was 8-fold higher than that of the strain harboring one copy. The activity of GS115/pAOalpha-5ROL 11# was then enhanced to 3080 U/mL in a shaking flask under optimized culture conditions. Subsequently, the endoplasmic reticulum-associated protein-degradation-related genes Ubc1 or/and Hrd1 were co expressed with ROL to further increase ROL expression. The activities of the recombinant strains, GS115/5ROL-Ubc1 22#, -Hrd1 15#, and -Hrd1-Ubc1 1#, were 4000 U/mL, 4200 U/mL, and 4750 U/mL, which was 29.9%, 36.4%, and 54.2% higher, respectively, than that observed in GS115/pAOalpha-5ROL 11#. Using the combined strategy, ROL expression was improved 15.8-fold, with maximum GS115/5ROL-Hrd1 Ubc1 1# activity reaching 33,900 U/mL via a sorbitol/methanol co-feeding strategy in a 3-L fermenter and resulting in a 1.65-, 1.26-, and 1.14-fold enhancement relative to the activities observed in strains GS115/pAOalpha-5ROL 11#, GS115/5ROL-Ubc1 22#, and GS115/5ROL-Hrd1 15#, respectively. These results indicated that heterologous overexpression of ROL in P. pastoris using this combined strategy is feasible for large-scale industrialization.

Biotechnology offers an alternative route to produce chitosans and more importantly, specific chitosan structures tailored to the needs of a diversity of industries. However, for biotech chitosans and products thereof to be commercialised, legislation should not create a burden. Here, the requirements of the EU regulatory framework have been analysed for the entire chain from research to development and production of several potential applications including nanomaterials. The animal or biotechnological origin leads to specific requirements in production of the raw material. No EU legislation dedicated to nanomaterials has been adopted. Instead, products are governed under the respective existing product legislation subject to extra requirements for safety assessment. While a knowledge gap exists on hazards related to nanomaterials in general, there is a need to establish realistic regulatory study designs to assess the safety of specific products. Furthermore, as many of the existing chitosan applications are not considered nanomaterials, it would be discriminatory to treat biotechnology derived products differently. PMID- 29452272 TI - pH-sensitive doxorubicin-conjugated prodrug micelles with charge-conversion for cancer therapy. AB - : Intelligent drug delivery systems with prolonged circulation time, reduced drug leakage in blood, target site-triggered drug release and endosomal escape are attractive and ideal for malignant tumor therapy. Herein, doxorubicin (DOX) conjugated smart polymeric micelles based on 4-carboxy benzaldehyde-grafted poly (L-lysine)-block-poly (methacryloyloxyethyl phosphorylcholine) (PLL(CB/DOX)-b PMPC) copolymer are prepared. DOX and electronegative 4-carboxy benzaldehyde are conjugated to the PLL block via an imine linkage and as a result, the drug loaded micelles exhibited the pH-triggered charge-conversion property and accelerated drug release at tumor pH. In vitro cytotoxicity studies of these DOX-loaded micelles exhibited great tumor inhibition against HeLa and 4T1 cells. Moreover, in mice models of breast cancer, these DOX-loaded micelles showed better anti tumor efficacy and less organ toxicity than free drug. In summary, these polymeric micelles could be applied as potential nanocarriers for cancer therapy. STATEMENT OF SIGNIFICANCE: As a typical anti-cancer drug, Doxorubicin (DOX) exhibited remarkable tumor inhibition but was limited by its low drug utilization and strong toxicity to organs. To overcome these challenges, we developed a DOX conjugated polymeric micelle as a nano drug carrier which was endowed with pH sensitivity and charge-conversion function. The structure of micelles would quickly disintegrate with surface charge-conversion in acidic environment, which would contribute to the endosomal escape and accelerated drug release. These DOX conjugated micelles would provide a promising platform for the efficient DOX delivery and better anti-cancer efficiency. PMID- 29452274 TI - Control of thiol-maleimide reaction kinetics in PEG hydrogel networks. AB - : Michael-type addition reactions are widely used to polymerize biocompatible hydrogels. The thiol-maleimide modality achieves the highest macromer coupling efficiency of the reported Michael-type pairs, but the resulting hydrogel networks are heterogeneous because polymerization is faster than the individual components can be manually mixed. The reactivity of the thiol dictates the overall reaction speed, which can be slowed in organic solvents and acidic buffers. Since these modifications also reduce the biocompatibility of resulting hydrogels, we investigated a series of biocompatible buffers and crosslinkers to decelerate gelation while maintaining high cell viability. We found that lowering the polymer weight percentage (wt%), buffer concentration, and pH slowed gelation kinetics, but crosslinking with an electronegative peptide was optimal for both kinetics and cell viability. Including a high glucose medium supplement in the polymer solvent buffer improved the viability of the cells being encapsulated without impacting gelation time. Slowing the speed of polymerization resulted in more uniform hydrogels, both in terms of visual inspection and the diffusion of small molecules through the network. However, reactions that were too slow resulted in non-uniform particle dispersion due to settling, thus there is a trade-off in hydrogel network uniformity versus cell distribution in the hydrogels when using these networks in cell applications. STATEMENT OF SIGNIFICANCE: The polymer network of thiol-maleimide hydrogels assembles faster than individual components can be uniformly mixed due to their fast gelation kinetics. The lack of homogeneity can result in variable cell-based assay results, resulting in batch-to-batch variability and limiting their use in predictive screening assays. Although these hydrogels are incredibly useful in tissue engineering, this network heterogeneity is a known problem in the field. We screened a variety of possible techniques to slow down the reaction speed and improve the homogeneity of these hydrogels, without sacrificing the viability and distribution of encapsulated cells. As others have reported, an electronegative crosslinker was the most effective technique to slow the reaction, but the chemical modification required is technically challenging. Of interest to a broad community, we screened buffer type, strength, and crosslinker electronegativity to find an optimal reaction speed that allows for high cell viability and small molecule diffusion, without allowing cells to settle during gelation, allowing application of these materials to the drug screening industry and tissue engineering community. PMID- 29452275 TI - A laser-activated multifunctional targeted nanoagent for imaging and gene therapy in a mouse xenograft model with retinoblastoma Y79 cells. AB - : Retinoblastoma (RB) is the most common intraocular malignancy of childhood that urgently needs early detection and effective therapy methods. The use of nanosized gene delivery systems is appealing because of their highly adjustable structure to carry both therapeutic and imaging agents. Herein, we report a folic acid (FA)-modified phase-changeable cationic nanoparticle encapsulating liquid perfluoropentane (PFP) and indocyanine green (ICG) (FA-CN-PFP-ICG, FCNPI) with good plasmid DNA (pDNA) carrying capacity, favorable biocompatibility, excellent photoacoustic (PA) and ultrasound (US) contrast, enhanced gene transfection efficiency and therapeutic effect. The liquid-gas phase transition of the FCNPI upon laser irradiation has provided splendid contrasts for US/PA dual-modality imaging in vitro as well as in vivo. More importantly, laser-mediated gene transfection with targeted cationic FCNPI nanoparticles demonstrated the best therapeutic effect compared with untargeted cationic nanoparticle (CN-PFP-ICG, CNPI) and neutral nanoparticle (NN-PFP-ICG, NNPI), both in vitro and in vivo. Such a multifunctional nanoagent is expected to combine dual-mode guided imaging with fewer side effects and proper therapeutic efficacy. These results establish an experimental foundation for the clinical detection of and therapy for RB. STATEMENT OF SIGNIFICANCE: We successfully constructed a multifunctional targeted cationic nanoparticle (FCNPI) and meticulously compared the variations in the plasmid loading capacity and binding to Y79 cells with NNPI, CNPI, and FCNPI. FCNPI exhibited favorable plasmid loading capability, splendid ability for targeting and only it could provide optimal US and PA contrast to background during a considerable long time. The FCNPI/pDNA + Laser system also exhibited the best therapeutic effect in vivo; this finding proposes a potential strategy for the evaluation of an efficient gene delivery nanocarrier for gene targeting therapy of RB tumor. Our study showed that there are great advantages of targeting FCNPI to provide PA/US imaging and to enlighten laser-mediated gene transfection. FCNPI is a very helpful multifunctional agent with potential. PMID- 29452273 TI - 3D bioprinted functional and contractile cardiac tissue constructs. AB - : Bioengineering of a functional cardiac tissue composed of primary cardiomyocytes has great potential for myocardial regeneration and in vitro tissue modeling. However, its applications remain limited because the cardiac tissue is a highly organized structure with unique physiologic, biomechanical, and electrical properties. In this study, we undertook a proof-of-concept study to develop a contractile cardiac tissue with cellular organization, uniformity, and scalability by using three-dimensional (3D) bioprinting strategy. Primary cardiomyocytes were isolated from infant rat hearts and suspended in a fibrin based bioink to determine the priting capability for cardiac tissue engineering. This cell-laden hydrogel was sequentially printed with a sacrificial hydrogel and a supporting polymeric frame through a 300-um nozzle by pressured air. Bioprinted cardiac tissue constructs had a spontaneous synchronous contraction in culture, implying in vitro cardiac tissue development and maturation. Progressive cardiac tissue development was confirmed by immunostaining for alpha-actinin and connexin 43, indicating that cardiac tissues were formed with uniformly aligned, dense, and electromechanically coupled cardiac cells. These constructs exhibited physiologic responses to known cardiac drugs regarding beating frequency and contraction forces. In addition, Notch signaling blockade significantly accelerated development and maturation of bioprinted cardiac tissues. Our results demonstrated the feasibility of bioprinting functional cardiac tissues that could be used for tissue engineering applications and pharmaceutical purposes. STATEMENT OF SIGNIFICANCE: Cardiovascular disease remains a leading cause of death in the United States and a major health-care burden. Myocardial infarction (MI) is a main cause of death in cardiovascular diseases. MI occurs as a consequence of sudden blocking of blood vessels supplying the heart. When occlusions in the coronary arteries occur, an immediate decrease in nutrient and oxygen supply to the cardiac muscle, resulting in permanent cardiac cell death. Eventually, scar tissue formed in the damaged cardiac muscle that cannot conduct electrical or mechanical stimuli thus leading to a reduction in the pumping efficiency of the heart. The therapeutic options available for end-stage heart failure is to undergo heart transplantation or the use of mechanical ventricular assist devices (VADs). However, many patients die while being on a waiting list, due to the organ shortage and limitation of VADs, such as surgical complications, infection, thrombogenesis, and failure of the electrical motor and hemolysis. Ultimately, 3D bioprinting strategy aims to create clinically applicable tissue constructs that can be immediately implanted in the body. To date, the focus on replicating complex and heterogeneous tissue constructs continues to increase as 3D bioprinting technologies advance. In this study, we demonstrated the feasibility of 3D bioprinting strategy to bioengineer the functional cardiac tissue that possesses a highly organized structure with unique physiological and biomechanical properties similar to native cardiac tissue. This bioprinting strategy has great potential to precisely generate functional cardiac tissues for use in pharmaceutical and regenerative medicine applications. PMID- 29452277 TI - Association Between Obesity and Acute Severity Among Patients Hospitalized for Asthma Exacerbation. AB - BACKGROUND: Although studies have demonstrated relations between obesity and incident asthma, little is known about the association of obesity with acute severity in adults hospitalized for asthma exacerbation. OBJECTIVES: To investigate the association of obesity with acute severity of asthma exacerbation. METHODS: This is a retrospective cohort study using population based data of 8 geographically diverse US states from 2010 through 2013. We included adults (age 18-54 years) hospitalized for asthma exacerbation. The outcome measures were markers of acute severity-use of mechanical ventilation (defined by noninvasive positive pressure ventilation and/or invasive mechanical ventilation) and hospital length of stay. To determine the association of obesity with each outcome, we fit multivariable models adjusting for patient-level confounders (eg, age, sex, race/ethnicity, primary insurance, quartiles for household income, residential status, and comorbidities) and potential patient clustering within hospitals. RESULTS: Among the 72,086 patients hospitalized for asthma exacerbation, 24% were obese. Obesity was associated with a significantly higher risk of any mechanical ventilation use (8.3% vs 5.0%; adjusted odds ratio [OR], 1.77; 95% CI, 1.63-1.92; P < .001) driven by the higher risk of noninvasive positive pressure ventilation use (7.2% vs 3.4%; adjusted OR, 2.14; 95% CI, 1.96 2.35; P < .001). Likewise, obese patients were more likely to have a hospital length of stay of 3 or more days compared with nonobese patients (59.4% vs 46.5%; adjusted OR, 1.37; 95% CI, 1.32-1.43; P < .001). These findings were consistent with stratifications by age, sex, and race/ethnicity. CONCLUSIONS: In this population-based study of adults hospitalized for asthma exacerbation, obesity was associated with higher acute severity. PMID- 29452278 TI - G-quadruplexes in Prague: A Bohemian Rhapsody. AB - The Sixth International Meeting on Quadruplex Nucleic Acids was held at the Hotel Internationale in Prague, Czech Republic from 31 May - 3 June 2017. A vibrant interdisciplinary community of over 300 scientists gathered to share their newest results in this exciting field and exchange ideas for further investigations. PMID- 29452279 TI - Biophysical methods: Complementary tools to study the influence of human steroid hormones on the liposome membrane properties. AB - Human steroid hormones are involved in many aspects of physiology and have long been known to exert rapid and delayed effects. They are lipophilic molecules which can be incorporated into the lipid membranes. Through non-covalent interactions they can alter the properties of the membrane, including fluidity, lipid raft formation and others. In this review, different biophysical techniques were described to study the interaction of human steroid hormones with biological and biomimetic membranes such as differential scanning calorimetry, electron paramagnetic resonance, fluorescence spectroscopy and Fourier transform infrared spectroscopy. The aim of this review is to overview the results of these complementary biophysical techniques summarizing the effects of these hormones on thermotropic and dynamic membrane properties. Meanwhile, the disorder induced by human steroid hormones is discussed in terms of hydrophobicity and chemical structure. PMID- 29452280 TI - Sticholysin II-mediated cytotoxicity involves the activation of regulated intracellular responses that anticipates cell death. AB - Sticholysin II (StII) is a pore-forming toxin of biomedical interest that belongs to the actinoporin protein family. Sticholysins are currently under examination as an active immunomodulating component of a vaccinal platform against tumoral cells and as a key element of a nucleic acids delivery system to cell cytosol. These proteins form pores in the plasma membrane leading to ion imbalance and cell lysis. However, the intracellular mechanisms triggered by actinoporins upon binding to membranes and its consequences for cell death are barely understood. Here, we have examined the cytotoxicity and intracellular responses induced by StII upon binding to human B-cell lymphoma Raji in vitro. StII cytotoxicity involves a functional actin cytoskeleton, induces cellular swelling, lysis and the concomitant release of cytosol content. In addition, StII induces calcium release mainly from the Endoplasmic Reticulum, activates Mitogen-Activated Protein Kinase ERK and impairs mitochondrial membrane potential. Furthermore, StII stimulates the expression of receptor interacting protein kinase 1 (RIP1), normally related to different forms of regulated cell death such as apoptosis and necroptosis. In correspondence, necrostatin-1, an inhibitor of this kinase, reduces StII cytotoxicity. However, the mechanism of cell death activated by StII does not involve caspases activation, typical molecular features of apoptosis and pyroptosis. Our results suggest that, beyond pore-formation and cell lysis, StII induced cytotoxicity could involve other regulated intracellular mechanisms connected to RIP1-MEK1/2 -ERK1/2- pathways. This opens new perspectives and challenges the general point of view that these toxins induce a completely unregulated mechanism of necrotic cell death. This study contributes to a better understanding of the molecular mechanisms involved in toxin-cell interaction and the implications for cell functioning, with connotation for the exploitations of these toxins in clinical settings. PMID- 29452276 TI - Application of targeted mass spectrometry in bottom-up proteomics for systems biology research. AB - The enormous diversity of proteoforms produces tremendous complexity within cellular proteomes, facilitates intricate networks of molecular interactions, and constitutes a formidable analytical challenge for biomedical researchers. Currently, quantitative whole-proteome profiling often relies on non-targeted liquid chromatography-mass spectrometry (LC-MS), which samples proteoforms broadly, but can suffer from lower accuracy, sensitivity, and reproducibility compared with targeted LC-MS. Recent advances in bottom-up proteomics using targeted LC-MS have enabled previously unachievable identification and quantification of target proteins and posttranslational modifications within complex samples. Consequently, targeted LC-MS is rapidly advancing biomedical research, especially systems biology research in diverse areas that include proteogenomics, interactomics, kinomics, and biological pathway modeling. With the recent development of targeted LC-MS assays for nearly the entire human proteome, targeted LC-MS is positioned to enable quantitative proteomic profiling of unprecedented quality and accessibility to support fundamental and clinical research. Here we review recent applications of bottom-up proteomics using targeted LC-MS for systems biology research. SIGNIFICANCE: Advances in targeted proteomics are rapidly advancing systems biology research. Recent applications include systems-level investigations focused on posttranslational modifications (such as phosphoproteomics), protein conformation, protein-protein interaction, kinomics, proteogenomics, and metabolic and signaling pathways. Notably, absolute quantification of metabolic and signaling pathway proteins has enabled accurate pathway modeling and engineering. Integration of targeted proteomics with other technologies, such as RNA-seq, has facilitated diverse research such as the identification of hundreds of "missing" human proteins (genes and transcripts that appear to encode proteins but direct experimental evidence was lacking). PMID- 29452281 TI - Incidence and risk factors of postoperative neurologic decline after complex adult spinal deformity surgery: results of the Scoli-RISK-1 study. AB - BACKGROUND CONTEXT: Significant variability in neurologic outcomes after surgical correction for adult spinal deformity (ASD) has been reported. Risk factors for decline in neurologic motor outcomes are poorly understood. PURPOSE: The objective of the present investigation was to identify the risk factors for postoperative neurologic motor decline in patients undergoing complex ASD surgery. STUDY DESIGN/SETTING: This is a prospective international multicenter cohort study. PATIENT SAMPLE: From September 2011 to October 2012, 272 patients undergoing complex ASD surgery were prospectively enrolled in a multicenter, international cohort study in 15 sites. OUTCOME MEASURES: Neurologic decline was defined as any postoperative deterioration in American Spinal Injury Association lower extremity motor score (LEMS) compared with preoperative status. METHODS: To identify risk factors, 10 candidate variables were selected for univariable analysis from the dataset based on clinical relevance, and a multivariable logistic regression analysis was used with backward stepwise selection. RESULTS: Complete datasets on 265 patients were available for analysis and 61 (23%) patients showed a decline in LEMS at discharge. Univariable analysis showed that the key factors associated with postoperative neurologic deterioration included older age, lumbar-level osteotomy, three-column osteotomy, and larger blood loss. Multivariable analysis revealed that older age (odds ratio [OR]=1.5 per 10 years, 95% confidence interval [CI] 1.1-2.1, p=.005), larger coronal deformity angular ratio [DAR] (OR=1.1 per 1 unit, 95% CI 1.0-1.2, p=.037), and lumbar osteotomy (OR=3.3, 95% CI 1.2-9.2, p=.022) were the three major predictors of neurologic decline. CONCLUSIONS: Twenty-three percent of patients undergoing complex ASD surgery experienced a postoperative neurologic decline. Age, coronal DAR, and lumbar osteotomy were identified as the key contributing factors. PMID- 29452282 TI - Load-sharing through elastic micro-motion accelerates bone formation and interbody fusion. AB - BACKGROUND CONTEXT: Achieving a successful spinal fusion requires the proper biological and biomechanical environment. Optimizing load-sharing in the interbody space can enhance bone formation. For anterior cervical discectomy and fusion (ACDF), loading and motion are largely dictated by the stiffness of the plate, which can facilitate a balance between stability and load-sharing. The advantages of load-sharing may be substantial for patients with comorbidities and in multilevel procedures where pseudarthrosis rates are significant. PURPOSE: We aimed to evaluate the efficacy of a novel elastically deformable, continuously load-sharing anterior cervical spinal plate for promotion of bone formation and interbody fusion relative to a translationally dynamic plate. STUDY DESIGN/SETTING: An in vivo animal model was used to evaluate the effects of an elastically deformable spinal plate on bone formation and spine fusion. METHODS: Fourteen goats underwent an ACDF and received either a translationally dynamic or elastically deformable plate. Animals were followed up until 18 weeks and were evaluated by plain x-ray, computed tomography scan, and undecalcified histology to evaluate the rate and quality of bone formation and interbody fusion. RESULTS: Animals treated with the elastically deformable plate demonstrated statistically significantly superior early bone formation relative to the translationally dynamic plate. Trends in the data from 8 to 18 weeks postoperatively suggest that the elastically deformable implant enhanced bony bridging and fusion, but these enhancements were not statistically significant. CONCLUSIONS: Load-sharing through elastic micro-motion accelerates bone formation in the challenging goat ACDF model. The elastically deformable implant used in this study may promote early bony bridging and increased rates of fusion, but future studies will be necessary to comprehensively characterize the advantages of load-sharing through micro-motion. PMID- 29452283 TI - Posterolateral fusion (PLF) versus transforaminal lumbar interbody fusion (TLIF) for spondylolisthesis: a systematic review and meta-analysis. AB - BACKGROUND CONTEXT: Lumbar fusion is an effective and durable treatment for symptomatic lumbar spondylolisthesis; however, the current literature provides insufficient evidence to recommend an optimal surgical fusion strategy. PURPOSE: The present study aims to compare the clinical outcomes, fusion rates, blood loss, and operative times between open posterolateral lumbar fusion (PLF) alone and open transforaminal lumbar interbody fusion (TLIF) + posterolateral fusion for spondylolisthesis. STUDY DESIGN: This is a systematic literature review and meta-analysis of English language studies for the treatment of spondylolisthesis with PLF versus PLF + TLIF. PATIENT SAMPLE: Data were obtained from published randomized controlled trials (RCTs) and retrospective cohort studies. OUTCOME MEASURES: Clinical outcomes included Oswestry Disability Index (ODI), back pain, leg pain, and health-related quality of life (HRQOL) scores. Fusion rate, operative time, blood loss, and infection rate were also assessed. METHODS: A literature search of three electronic databases was performed to identify investigations performed comparing PLF alone with PLF + TLIF for treatment of low grade lumbar spondylolisthesis. The summary effect size was assessed from pooling observational studies for each of the outcome variables, with odds ratios (ORs) used for fusion and infection rate, mean difference used for improvement in ODI and leg pain as well as operative time and blood loss, and standardized mean difference used for improvement in back pain and HRQOL outcomes. Studies were weighed based on the inverse of the variance and heterogeneity. Heterogeneity was assessed using the I2-an estimate of the error caused by between-study variation. Effect sizes from the meta-analysis were then compared with data from the RCTs to assess congruence in outcomes. RESULTS: The initial literature search yielded 282 unique, English language studies. Seven were determined to meet our inclusion criteria and were included in our qualitative analysis. Five observational studies were included in our quantitative meta-analysis. The pooled fusion success rates were 84.7% (100/118) in the PLF group and 94.3% (116/123) in the TLIF group. Compared with TLIF patients, PLF patients had significantly lower odds of achieving solid arthrodesis (OR 0.33, 95% confidence interval [CI] 0.13 0.82, p=.02; I2=0%). With regard to improvement in back pain, the point estimate for the effect size was -0.27 (95% CI -0.43 to -0.10, p=.002; I2=0%), in favor of the TLIF group. For ODI, the pooled estimate for the effect size was -3.73 (95% CI -7.09 to -0.38, p=.03; I2=35%), significantly in favor of the TLIF group. Operative times were significantly shorter in the PLF group, with a summary effect size of -25.55 (95% CI -43.64 to -7.45, p<.01; I2=54%). No significant difference was observed in leg pain, HRQOL improvement, blood loss, or infection rate. Our meta-analysis results were consistent with RCTs, in favor of TLIF for achieving radiographic fusion and greater improvement in ODI and back pain. CONCLUSIONS: Our results demonstrate that for patients undergoing fusion for spondylolisthesis, TLIF is superior to PLF with regard to achieving radiographic fusion. However, current data only provide weak support, if any, favoring TLIF over PLF for clinical improvement in disability and back pain. PMID- 29452284 TI - "Microendoscopic" versus "pure endoscopic" surgery for spinal intradural mass lesions: a comparative study and review. AB - BACKGROUND CONTEXT: Endoscopy is increasingly being used for minimal invasiveness and panoramic visualization, with unclear efficacy and safety among spinal intradural mass. OBJECTIVE: The present study aims to compare microendoscopic and pure endoscopic surgery for spinal intradural lesions. MATERIALS AND METHODS: Spinal intradural lesions operated using endoscopic or access ports were categorized into "microendoscopic" (predominant microscope use) or "pure endoscopic" (stand-alone endoscopy) surgery, and were studied with respect to clinico-radiological features, techniques, perioperative course, histopathology, clinical, and radiological outcome at minimum of 3 months. RESULTS: Among 34 patients studied, the initial 15 had "microendoscopic" surgery, 16 had "pure endoscopic" surgery, and 3 had "mixed" use. There were 18 nerve sheath tumors, 6 meningiomas, 6 cysts, 2 ependymomas, ranging in size from 1.5 to as large as 6.8 cm (21%>=4 cm), including 4 in craniovertebral junction (CVJ). Intermuscular or paraspinous approach was utilized, followed by small bony fenestration or interlaminar corridor. Even larger tumors could be excised using expandable ports or "sliding delivery" technique. Although visualization of sides and angles was better with endoscope, hemostasis and dural closure had steep learning curve, necessitating the use of microscope in the initial cases. Clinical improvement and radiological resolution could be achieved in all. There was no significant difference between the groups. The change in Nurick grade had significant correlation with only the dimension of lesion (p=.03) and preoperative grade (p=.05). CONCLUSIONS: This is probably the first report of spinal endoscopy for intradural tumors in CVJ or as big as 7 cm. Endoscopy is effective and safe for even large tumors with better visualization of sides and angles, albeit with hemostasis and dural closure having initial learning curve. Wide heterogeneity of surgical terminologies in the literature on these procedures warrants consensus for uniform reporting. PMID- 29452285 TI - Risk factors for perioperative morbidity in spine surgeries of different complexities: a multivariate analysis of 1,009 consecutive patients. AB - BACKGROUND CONTEXT: There is a broad spectrum of complications during or after surgical procedures, with differing incidences reported in the published literature. Heterogeneity can be explained by the lack of an established evidence based classification system for documentation and classification of complications in a standardized manner. PURPOSE: The objective of this study was to identify predictive risk factors for perioperative and early postoperative morbidities in spine surgeries of different complexities in a large cohort of consecutive patients. STUDY DESIGN: This study is a retrospective case series. OUTCOME MEASURES: The outcome measures are the occurrence of perioperative and early postoperative morbidities. METHODS: A classification of surgical complexity (Grades I-III) was created and applied to 1,009 patients who consecutively underwent spine surgery at a single university hospital. The incidence and the type of perioperative and early postoperative morbidities were documented. Multivariate binary logistic regression analyzed risk factors for (1) hospital stay of >=10 days, (2) intermediate care unit (IMC) stay of >=24 hours, (3) blood loss of >500 mL, and occurrence of a (4) surgical or (5) medical morbidity. RESULTS: A deviation from the regular postoperative course (defined as "morbidity") included surgical reasons, such as relapse of symptoms of any kind (3.3%), wound healing problems (2.4%), implant-associated complications (1.6%), postoperative neurologic deficits (1.5%), infection (1.5%), fracture (0.8%), and dural tear in need of revision (0.6%). Medical reasons included anemia (1.8%), symptomatic electrolyte derailment (1.0%), and cardiac complications (0.7%), among others. An independent risk factor associated with a surgical reason for an irregular postoperative course was male gender. Risk factors associated with a medical reason for an irregular postoperative course were identified as preoperatively high creatinine levels, higher blood loss, and systemic steroid use. Independent risk factors for a prolonged hospitalization were preoperatively high C-reactive protein level, prolonged postoperative IMC stay, and revision surgery. Spinal stabilization or fusion surgery, particularly if involving the lumbosacral spine, age, and length of surgery were associated with blood loss of >500 mL. Higher surgical complexity, involvement of the pelvis in instrumentation, American Society of Anesthesiologists Grade >=III, and preoperatively higher creatinine levels were associated with a postoperative IMC stay of >24 hours. CONCLUSIONS: The present study confirms several modifiable and non-modifiable risk factors for perioperative and early postoperative morbidities in spine surgery, among which surgical factors (such as complexity, revision surgery, and instrumentation, including the pelvis) play a crucial role. A classification of surgical complexity is proposed and validated. PMID- 29452286 TI - Risk factor analysis of adjacent segment disease requiring surgery after short lumbar fusion: the influence of rheumatoid arthritis. AB - BACKGROUND CONTEXT: The influence of rheumatoid arthritis (RA) on the lumbar spine has received relatively little attention compared with cervical spine, and few studies have been conducted for adjacent segment disease (ASD) after lumbar fusion in patients with RA. PURPOSE: The present study aims to determine the incidence of ASD requiring surgery (ASDrS) after short lumbar fusion and to evaluate risk factors for ASDrS, including RA. STUDY DESIGN: This is a retrospective cohort study. PATIENT SAMPLE: The present study included 479 patients who underwent lumbar spinal fusion of three or fewer levels, with the mean follow-up period of 51.2 (12-132) months. OUTCOME MEASURES: The development of ASD and consequent revision surgery were reviewed using follow-up data. METHODS: The ASDrS-free survival rate of adjacent segments was calculated through Kaplan-Meier method. The log-rank test and Cox regression analysis were used to evaluate risk factors comprising RA, age, gender, obesity, osteoporosis, diabetes, smoking, surgical method, and the number of fusion segments. RESULTS: After short lumbar fusion, revision surgery for ASD was performed in 37 patients (7.7%). Kaplan-Meier analysis predicted that the ASDrS-free survival rate of adjacent segments was 97.8% at 3 years, 92.7% at 5 years, and 86.8% at 7 years. In risk factor analysis, patients with RA showed a 4.5 times higher risk of ASDrS than patients without RA (p<.001), and patients with three-segment fusion showed a 2.7 times higher risk than patients with one- or two-segment fusion (p=.005). CONCLUSIONS: Adjacent segment disease requiring surgery was predicted in 13.2% of patients at 7 years after short lumbar fusion. Rheumatoid arthritis and the number of fusion segments were confirmed as risk factors. PMID- 29452287 TI - Dental pulp stem cell-derived chondrogenic cells demonstrate differential cell motility in type I and type II collagen hydrogels. AB - BACKGROUND CONTEXT: Advances in the development of biomaterials and stem cell therapy provide a promising approach to regenerating degenerated discs. The normal nucleus pulposus (NP) cells exhibit similar phenotype to chondrocytes. Because dental pulp stem cells (DPSCs) can be differentiated into chondrogenic cells, the DPSCs and DPSCs-derived chondrogenic cells encapsulated in type I and type II collagen hydrogels can potentially be transplanted into degenerated NP to repair damaged tissue. The motility of transplanted cells is critical because the cells need to migrate away from the hydrogels containing the cells of high density and disperse through the NP tissue after implantation. PURPOSE: The purpose of this study was to determine the motility of DPSC and DPSC-derived chondrogenic cells in type I and type II collagen hydrogels. STUDY DESIGN/SETTING: The time lapse imaging that recorded cell migration was analyzed to quantify the cell migration velocity and distance. METHODS: The cell viability of DPSCs in native or poly(ethylene glycol) ether tetrasuccinimidyl glutarate (4S StarPEG)-crosslinked type I and type II collagen hydrogels was determined using LIVE/DEAD cell viability assay and AlamarBlue assay. DPSCs were differentiated into chondrogenic cells. The migration of DPSCs and DPSC-derived chondrogenic cells in these hydrogels was recorded using a time lapse imaging system. This study was funded by the Regional Institute on Aging and Wichita Medical Research and Education Foundation, and the authors declare no competing interest. RESULT: DPSCs showed high cell viability in non-crosslinked and crosslinked collagen hydrogels. DPSCs migrated in collagen hydrogels, and the cell migration speed was not significantly different in either type I collagen or type II collagen hydrogels. The migration speed of DPSC-derived chondrogenic cells was higher in type I collagen hydrogel than in type II collagen hydrogel. Crosslinking of type I collagen with 4S-StarPEG significantly reduced the cell migration speed of DPSC derived chondrogenic cells. CONCLUSIONS: After implantation of collagen hydrogels encapsulating DPSCs or DPSC-derived chondrogenic cells, the cells can potentially migrate from the hydrogels and migrate into the NP tissue. This study also explored the differential cell motility of DPSCs and DPSC-derived chondrogenic cells in these collagen hydrogels. PMID- 29452289 TI - Polypharmacy in people with dementia: Associations with adverse health outcomes. AB - Polypharmacy has been linked to higher risks of hospitalisation and death in community samples. It is commonly present in people with dementia but these risks have rarely been studied in this population. We aimed to investigate associations between polypharmacy and emergency department attendance, any and unplanned hospitalisation, and mortality in patients with dementia. Using a large mental health care database in South London, linked to hospitalisation and mortality data, we assembled a retrospective cohort of patients diagnosed with dementia. We ascertained number of medications prescribed at the time of dementia diagnosis and conducted multivariate Cox regression analyses. Of 4668 patients with dementia identified, 1128 (24.2%) were prescribed 4-6 medications and 739 (15.8%) >=7 medications. Compared to those using 0-3 medications, patients with dementia using 4-6 or >=7 agents had an increased risk of emergency department attendance (hazard ratio 1.20/1.35), hospitalisation (hazard ratio 1.12/1.32), unplanned hospital admission (hazard ratio 1.12/1.25), and death within two years (hazard ratio 1.29/1.39) after controlling for potential confounders. We found evidence of a dose response relationship with each additional drug at baseline increasing the risk of emergency department attendance and mortality by 5% and hospitalisation by 3%. In conclusion, polypharmacy at dementia diagnosis is associated with a higher risk of adverse health outcomes. Future research is required to elucidate which specific agents underlie this relationship and if reduction of inappropriate prescribing is effective in preventing these outcomes in dementia. PMID- 29452290 TI - Lean body weight is the best scale for venous thromboprophylaxis algorithm in severely obese patients undergoing bariatric surgery. AB - Severely obese patients undergoing bariatric surgery (BS) are at increased risk for venous thromboembolism (VTE). How standard low molecular weight heparin (LMWH) regimen should be adapted to provide both sufficient efficacy and safety in this setting is unclear. We aimed to compare the influence of four body size descriptors (BSD) on peak anti-Xa levels in BS obese patients receiving LMWH fixed doses to identify which one had the greatest impact. One hundred and thirteen BS obese patients [median body mass index (BMI), 43.3 kg/m2 (IQR, 40.6 48.7 kg/m2)] receiving subcutaneous dalteparin 5000 IU twice daily were included in this prospective monocenter study. Peak steady-state anti-Xa levels were measured peri-operatively following thromboprophylaxis initiation. Only 48% of patients achieved target anti-Xa levels (0.2-0.5 IU/ml). In univariate analysis, age, gender, total body-weight (TBW), lean body-weight (LBW), ideal body-weight (IBW), BMI and estimated glomerural filtration rate (eGFR) were associated with anti-Xa levels. The strongest negative association was observed with LBW (r = 0.56, p < .0001). Receiver operating characteristic curves indicated that among BSD, LBW (cut-off >55.8 kg) had the highest sensitivity (73%) and specificity (69%) to predict sub-prophylactic anti-Xa levels. In multivariate analysis, LBW and eGFR remained associated with anti-Xa levels (beta = -0.47 +/- 0.08, p < .0001 and beta = -0.19 +/- 0.08; p = .02, respectively). In BS morbidly obese patients receiving LMWH for thromboprophylaxis after BS, LBW and eGFR are the main determinants of anti-Xa level, and could be proposed in LMWH-based thromboprophylaxis dosing algorithms. The efficacy of a LBW-scale based dosing algorithm for optimal VTE prevention deserves further prospective randomized trials. PMID- 29452291 TI - Pharmacokinetic models to assist the prescriber in choosing the best tacrolimus dose. AB - Due to a high inter-individual variability in its pharmacokinetics, tacrolimus dose individualization is mandatory. Even though the expert opinion has defined the area under the curve (AUC) as the best marker to use when performing dose adjustment of tacrolimus, most centres only use trough levels. Multiple targets have been proposed for this parameter and physicians rely largely on their personal experience when making a decision about dose adjustment. Several population pharmacokinetics models (POPPK) allowing AUC determination have been developed, but only a few are actually used in routine practice for dose individualization. These POPPK models can also be used to perform Monte Carlo simulations that help to establish different dosing rules or to anticipate the pharmacokinetics of tacrolimus in particular populations, without conducting clinical trials. Various available applications of POPPK models to assist the prescriber in choosing the best tacrolimus dose are discussed in this paper as well as the difficulties in introducing them into routine therapeutic drug monitoring. PMID- 29452288 TI - Repetitive TLR3 activation in the lung induces skeletal muscle adaptations and cachexia. AB - Due to immunosenescence, older adults are particularly susceptible to lung-based viral infections, with increased severity of symptoms in those with underlying chronic lung disease. Repeated respiratory viral infections produce lung maladaptations, accelerating pulmonary dysfunction. Toll like 3 receptor (TLR3) is a membrane protein that senses exogenous double-stranded RNA to activate the innate immune response to a viral infection. Polyinosinic-polycytidylic acid [poly(I:C)] mimics double stranded RNA and has been shown to activate TLR3. Utilizing an established mouse viral exacerbation model produced by repetitive intranasal poly(I:C) administration, we sought to determine whether repetitive poly(I:C) treatment induced negative muscle adaptations (i.e. atrophy, weakness, and loss of function). We determined skeletal muscle morphological properties (e.g. fiber-type, fiber cross-sectional area, muscle wet mass, etc.) from a treated group ((poly(I:C), n = 9) and a sham-treated control group (PBS, n = 9); age approximately 5 months. In a subset (n = 4 for both groups), we determined in vivo physical function (using grip test for strength, rotarod for overall motor function, and treadmill for endurance) and muscle contractile properties with in vitro physiology (in the EDL, soleus and diaphragm). Our findings demonstrate that poly(I:C)-treated mice exhibit both muscle morphological and functional deficits. Changes of note when comparing poly(I:C)-treated mice to PBS-treated controls include reductions in fiber cross-sectional area (-27% gastrocnemius, 25% soleus, -16% diaphragm), contractile dysfunction (soleus peak tetanic force, 26%), muscle mass (gastrocnemius -19%, soleus -23%), physical function (grip test -34%), body mass (-20%), and altered oxidative capacity (140% increase in succinate dehydrogenase activity in the diaphragm, but 66% lower in the gastrocnemius). Our data is supportive of a new model of cachexia/sarcopenia that has potential for future research into the mechanisms underlying muscle wasting. PMID- 29452292 TI - Prevalence, risk factors and genetic characterization of Toxoplasma gondii in sick pigs and stray cats in Jiangsu Province, eastern China. AB - Toxoplasma gondii is an obligate intracellular parasitic protozoan with a worldwide distribution. The parasites in edible tissues of pigs and oocysts from cats are the major sources of T. gondii infection in humans. However, there are no data from sick pigs in veterinary clinics or from stray cats in Jiangsu Province, eastern China. In total, biological samples from 141 sick pigs and 64 stray cats were collected from this region. The rate of T. gondii infection in sick pigs was 46.81% using a polymerase chain reaction (PCR), and the overall prevalence of toxoplasmosis in stray cats was 34.38% by PCR and an enzyme-linked immunosorbent assay (ELISA). T. gondii was significantly more prevalent in lungs and heart than in liver and spleen (P < 0.05). Age and geographic region were considered to be the main risk factors associated with T. gondii infection in these pigs. The DNA samples from 17 sick pigs and seven stray cats, were successfully genotyped by multilocus PCR-restriction fragment length polymorphism (PCR-RFLP) with 10 genetic markers [SAG1, SAG2 (5'-3'SAG2, alt. SAG2), SAG3, GRA6, PK1, c22-8, c29-2, BTUB, L358 and Apico]. Six distinct genotypes were found, which were designated ToxoDB PCR-RFLP genotypes #9 (Chinese I), #10 (Type I), #213, and #89, and New 1 and New 2. Chinese I is the most prevalent T. gondii genotype in this region. The two new genotypes (designated New 1 and New 2) are reported and the ToxoDB PCR-RFLP genotype #89 is found for the first time in China. Such information will be useful for the prevention, diagnosis and treatment of porcine toxoplasmosis in Jiangsu Province, eastern China. PMID- 29452293 TI - Genetic diversity and functional analysis of oipA gene in association with other virulence factors among Helicobacter pylori isolates from Iranian patients with different gastric diseases. AB - Helicobacter pylori (H. pylori) is one of the most genetically diverse bacterial pathogens that persistently colonizes the human gastric epithelium. This remarkable genomic plasticity may act as a driving force for successful adaptation and persistence of the bacteria in the harsh gastric environment. Outer inflammatory protein A (OipA) encoded by oipA gene (HP0638/hopH) is a member of the outer membrane proteins (OMPs) of H. pylori involved in induction of IL-8 secretion and is associated with development of peptic ulcer and gastric cancer. Expression of OipA is regulated by phase variation within a CT dinucleotide repeat motif of the oipA gene. In this study we carried out direct DNA sequence analysis of 53 amplified fragments to investigate the oipA "On/Off" status among Iranian H. pylori isolates from patients with various gastric diseases. The prevalence of cagL, cagA, EPIYA motifs, vacA alleles, babA2 and sabA genotypes as well as cagPAI integrity of the isolates were determined by PCR. Our results demonstrated a high prevalence of strains with functional oipA status (79%) and significant associations were found between functional oipA and cagA (P = 0.027) and vacA s1m1 (P = 0.022) genotypes. The vacA s1m2 genotype was also found to be statistically associated with PUD (P = 0.0001). Interestingly, we showed that H. pylori strains with intact cagPAI co-expressed oipA gene in a significant synergistic relationship (P < 0.01). However, no significant association was observed between the functional oipA status and clinical outcomes (P > 0.05). In conclusion, our findings denotes great diversity in the number and pattern of CT dinucleotide repeats of oipA among Iranian H. pylori strains. The synergistic link between functional oipA and other important virulence factors is proposed to be critical in the pathogenesis of H. pylori, which needs further studies with a larger number of samples. PMID- 29452294 TI - Vitamin D pathway genetic variants are able to influence sofosbuvir and its main metabolite pharmacokinetics in HCV mono-infected patients. AB - Vitamin D levels and genetic variants were associated with drug outcome/toxicity and concentrations. The plasma exposure of GS-331007, the main sofosbuvir metabolite, has been related to SVR. We evaluated the impact of polymorphisms in genes (CYP27B1, CYP24A1, VDBP and VDR) related to vitamin D pathway on sofosbuvir and GS-331007 plasma levels in HCV mono-infected patients at one month of treatment. Polymorphisms were investigated through real-time PCR; drug plasma quantification was performed through a UHPLC-MS/MS method. GS-331007 levels were associated with CYP24A1rs2248359 and VDRCdx2 variants in all the analyzed patients and linear regression analysis showed that sex, body mass index, HCV genotype, baseline estimated glomerular filtration rate, VDRCdx2AG/GG and CYP27B1 1260TT genotypes significantly predict concentrations. We performed sub-analyses considering the HCV genotype and the concomitant drug, identifying polymorphisms associated with GS-331007 concentrations. This is the first study focusing on vitamin D pathway gene variants and DAAs concentrations, but further studies are required. PMID- 29452295 TI - What Types of Treatment Are Provided for Patients With Carpal Tunnel Syndrome? A Retrospective Analysis of Commercial Insurance. AB - BACKGROUND: Treatment of carpal tunnel syndrome (CTS) in commercially insured patients across the spectrum of provider types rarely has been described. OBJECTIVE: To describe patterns of types of treatment for patients with CTS using a large commercial insurance database. DESIGN: Retrospective cohort descriptive study. SETTING: Administrative health data from the Clinformatics Data Mart (OptumInsight, Eden Prairie, MN). PATIENTS: Adults with a primary diagnosis of CTS seen from between January 2010 to December 2012 who had a total of 48 months of continuous data (12 months before diagnosis and 36 months after diagnosis) (n = 24,931). OUTCOMES: Frequency of types of treatment (heat, manual therapy, positioning, steroids, stretching, surgery) by number of treatments, number of visits, provider type, and characteristics. RESULTS: Fifty-four percent of patients received no reported treatment, and 50.4% had no additional visits. Surgery (42.5%) and positioning (39.8%) were the most frequent single treatments. Patients who were seen by orthopedist for their first visit more frequently received some treatment (75.1%) and at least 1 additional visit (74.1%) compared with those seen by general practitioners (59.5%, 57.5%, respectively) or other providers (65.4%, 68.4, respectively). Orthopedists more frequently prescribed positioning devices (26.8%) and surgery (36.8%) than general practitioners (18.8%, 14.1%, respectively) or other providers (15.7%, 19.7%, respectively). Older adults more frequently had CTS surgery, as did people who lived in the Midwest. Overall, only 24% of patients with CTS had surgery. CONCLUSIONS: For more than one-half of patients with CTS no treatment was provided after an initial visit. Surgery rates were much lower than what has previously been reported in the literature. Generally, patients with CTS receive treatments that are supported by current treatment guidelines. LEVEL OF EVIDENCE: NA. PMID- 29452296 TI - Development and Persistence of Suspected Neuropathic Pain After Total Knee Arthroplasty in Individuals With Osteoarthritis. AB - BACKGROUND: Despite the effectiveness of total knee arthroplasty (TKA) for osteoarthritis (OA), up to 20% will report knee pain 1 year after surgery. One possible reason is the development of neuropathic pain before or after TKA. OBJECTIVE: To longitudinally describe suspected neuropathic pain in patients pre- and post-TKA and to explore relations between pre-TKA suspected neuropathic pain and post-TKA outcomes. DESIGN: Prospective observational study. SETTING: Participants were recruited from orthopedic surgery clinics prior to inpatient elective primary TKA. PARTICIPANTS: Convenience sample of 135 patients were assessed for eligibility; 99 were enrolled and 74 completed the 6-month follow up. METHODS: Participants completed the Self-Leeds Assessment of Neuropathic Symptoms and Signs (S-LANSS) and outcome measures at baseline (pre-TKA) and 1 and 6 months post-TKA by postal survey. Demographic variables included age, gender, and comorbidities. Descriptive statistics were calculated for the presence of suspected neuropathic pain at each assessment and course of outcomes for various suspected neuropathic pain trajectories. Further, t-tests were used to compare outcomes between those with and without suspected neuropathic pain at each assessment. Multiple linear regressions assessed the relationship between baseline suspected neuropathic pain and 6-month outcomes. MAIN OUTCOME MEASUREMENTS: Intermittent and Constant Osteoarthritis Pain (ICOAP), Pain Catastrophizing Scale (PCS), and the Patient Health Questionnaire (PHQ-9) for depression. RESULTS: Suspected neuropathic pain was present in 35.5% of pre-TKA patients, 39.0% at 1 month, and 23.6% at 6 months post-TKA. Those with suspected neuropathic pain had higher scores for ICOAP total pain (P = .05), pain catastrophizing (P < .01), and depression (P < .01) at each assessment. After adjusting for potential confounding, pre-TKA suspected neuropathic pain did not predict ICOAP total pain or PHQ-9 depression scores at 6 months. CONCLUSIONS: Although 14% of individuals with knee OA had suspected neuropathic pain that persisted 6 months post-TKA and those with suspected neuropathic pain had higher levels of pain, catastrophizing, and depression, the clinical identification of neuropathic pain remains enigmatic. Preoperative suspected neuropathic pain, as measured by S-LANSS, may have limited prognostic value for post-TKA outcomes. LEVEL OF EVIDENCE: II. PMID- 29452297 TI - Lumbar Intraspinal Spindle Cell Rhabdomyosarcoma as a Rare Cause of Spinal Stenosis: A Case Report. AB - : Rhabdomyosarcoma (RMS) represents the most common sarcoma in childhood yet is extremely rare in adults, with only a handful of cases reported. Here we present a case of intraspinal spindle cell RMS in an adult who presented as a typical case of spinal stenosis. To our knowledge, this is the first reported case of lumbar intraspinal spindle cell RMS in an adult patient. Furthermore, RMS phenotypically presents more aggressively in adults compared with children. LEVEL OF EVIDENCE: V. PMID- 29452298 TI - Treatment and outcomes in patients with IgG4-related disease using the IgG4 responder index. AB - BACKGROUND: IgG4-related disease (IgG4-RD) is an autoimmune disease triggering an inflammatory cascade that leads to fibrosis. Outcome measures are limited and treatment options remain underexplored. OBJECTIVES: To assess the variation of the IgG4 responder index (IgG4-RI) in a cohort of IgG4-RD patients and to explore their treatments and outcomes. METHODS: We studied the clinical phenotype, severity of the disease and response to treatment in an ambispective multicenter cohort study including 14 different hospitals in Spain. All patients met the 2012 international consensus on pathology criteria for diagnosis. RESULTS: Sixty-eight patients were included, with a mean age of 53.4 years and predominance of male sex. The most commonly involved tissues were: retroperitoneum (33%), orbital pseudotumor (28%) and maxillary and paranasal sinuses (24%). IgG4-RI values were higher in patients with multiorgan disease and before treatment. After being treated, IgG4-RI values were lower, in accordance with the high rates of treatment response. Most patients received: glucocorticoids (GC), surgery, azathioprine (AZA), mofetil mycophenolate or rituximab. GC alone, GC plus surgery and GC plus AZA were given in the most of the IgG4-RD disease activity episodes. All treatments had high response rates but relapses and flares were common. CONCLUSIONS: IgG4-RI is a promising outcome measure in IgG4-RD, but still in development. Treatment algorithms are ill defined. GC and rituximab are the drugs with more evidence available. Disease modifying anti-rheumatic drugs may have a role in IgG4-RD and warrant more prospective studies. PMID- 29452299 TI - Non-celiac gluten intolerance in patients with scleroderma. PMID- 29452300 TI - Therapeutic strategy for rheumatoid arthritis patients who have achieved remission. AB - Once remission or low disease activity (LDA) is attained in established rheumatoid arthritis (RA) patients, attempting disease-modifying anti-rheumatic drug (DMARD) tapering appears to be a viable option to avoid patient overtreatment. Potential benefits include reduction in the treatment burden and the risk of adverse events, although the latter has not been demonstrated convincingly. The feasibility of DMARD discontinuation has been tested in numerous studies or trials. All have revealed a high risk of relapse, ranging from 56%-87% at one year. Although remission/LDA can usually be re-established by re-initiation of the previous treatment, the associated risk appears to be more harmful than beneficial. DMARD tapering, either by dose reduction or by injection spacing, is conceptually more acceptable and two superiority randomized controlled trials (RCTs) comparing half-dose etanercept to full-dose continuation demonstrated no significant difference at one year. By contrast, two equivalence RCTs that tested disease activity-guided dose optimization by progressive etanercept and adalimumab injection spacing versus continuation revealed an increased risk of acute flare. Interestingly, one of these also demonstrated the equivalence of increasing injection spacing and standard of care in terms of recurrent flare and overall disease activity over the 18-month follow-up period. The risk of structural damage progression was minimal or null. Reintroduction of DMARD at the previous dose was associated with remission being achieved in the majority of patients who flared. Tapering strategies that adhere to the Tight Control and Treat-to-Target principles appear to be suitable options for RA patients who have achieved sustained remission or low disease activity.

PMID- 29452303 TI - Effect of biologics on fatigue in psoriatic arthritis: A systematic literature review with meta-analysis. AB - OBJECTIVES: Fatigue is a significant issue in psoriatic arthritis. The objective was to assess the effect of biological disease modifying antirheumatic drugs and apremilast on fatigue in psoriatic arthritis randomised controlled trials and to compare this effect with the effect in the same trials, on pain, through a systematic literature review and meta-analysis. METHODS: A systematic literature review was performed up to January 2017 in PubMed, Embase and Cochrane databases. All randomized controlled trials in psoriatic arthritis of biological disease modifying antirheumatic drugs or apremilast, assessing fatigue (whatever the score used), were included. Data were collected by 2 assessors regarding levels of fatigue and pain at baseline and at the time point closest to 24 weeks after the treatment introduction. Pooled standardized mean differences were calculated using RevMan. RESULTS: After screening 295 publications, 7 randomised controlled trials were analysed: they pertained to adalimumab (n=2), certolizumab pegol (n=1), secukinumab (n=2), ustekinumab (n=1) and apremilast (n=1), compared to placebo. The studies included 2341 patients: weighted mean+/-standard deviation age: 48.6+/-1.3years, disease duration: 7.7+/-1.6years, 51.6% were females. Fatigue levels were high at baseline (Functional Assessment of Chronic Illness Therapy score: 28.7+/-2.4). The pooled standardized mean difference was, for fatigue -0.44 (95% confidence interval: -0.54, -0.35) and for pain, -0.62 (-0.73, -0.52). CONCLUSIONS: Biological disease modifying antirheumatic drugs and apremilast had a small effect on fatigue at 24 weeks in psoriatic arthritis randomized controlled trials and a higher effect on pain. These results are important to take into account in shared decision-making. PMID- 29452304 TI - The chondrocyte channelome: A narrative review. AB - Chondrocytes are the main cells in the extracellular matrix (ECM) of articular cartilage and possess a highly differentiated phenotype that is the hallmark of the unique physiological functions of this specialised load-bearing connective tissue. The plasma membrane of articular chondrocytes contains a rich and diverse complement of membrane proteins, known as the membranome, which defines the cell surface phenotype of the cells. The membranome is a key target of pharmacological agents and is important for chondrocyte function. It includes channels, transporters, enzymes, receptors, and anchors for intracellular, cytoskeletal and ECM proteins and other macromolecular complexes. The chondrocyte channelome is a sub-compartment of the membranome and includes a complete set of ion channels and porins expressed in these cells. Many of these are multi-functional proteins with "moonlighting" roles, serving as channels, receptors and signalling components of larger molecular assemblies. The aim of this review is to summarise our current knowledge of the fundamental aspects of the chondrocyte channelome, discuss its relevance to cartilage biology and highlight its possible role in the pathogenesis of osteoarthritis (OA). Excessive and inappropriate mechanical loads, an inflammatory micro-environment, alternative splicing of channel components or accumulation of basic calcium phosphate crystals can result in an altered chondrocyte channelome impairing its function. Alterations in Ca2+ signalling may lead to defective synthesis of ECM macromolecules and aggravated catabolic responses in chondrocytes, which is an important and relatively unexplored aspect of the complex and poorly understood mechanism of OA development.

PMID- 29452306 TI - Boundaries between familial Mediterranean fever and juvenile spondyloarthritis: Analysis of three French retrospective cohorts. AB - OBJECTIVES: Children with Familial Mediterranean fever may suffer from musculoskeletal involvement, somewhat difficult to distinguish from juvenile spondyloarthritis. The association of these two diseases has been scarcely reported in children. Objective of this work was to define the association of familial Mediterranean fever and juvenile spondyloarthritis in France. METHODS: Three cohorts of children with familial Mediterranean fever, juvenile spondyloarthritis, familial Mediterranean fever related juvenile spondyloarthritis, were retrospectively identified in the French reference center of auto-inflammatory diseases. Familial Mediterranean fever was defined according to Tel-Hashomer or Turkish pediatric criteria with at least one exon-10 MEFV-gene mutation. Juvenile spondyloarthritis was defined according to ILAR criteria. Patients with familial Mediterranean fever or juvenile spondyloarthritis were respectively compared to familial Mediterranean fever related juvenile spondyloarthritis patients. RESULTS: Sixteen children were identified as having familial Mediterranean fever related juvenile spondyloarthritis. The male/female ratio was 0.6, with median age at spondyloarthritis onset of 7.5years (3 16years). All carried at least one M694V variant in MEFV gene; 16.7% were HLA-B27 carriers. Compared to 83 familial Mediterranean fever patients, familial Mediterranean fever related juvenile spondyloarthritis patients had less frequently fever (P<0.01) and more frequently arthritis (P<0.05), enthesitis (P<0.001), inflammatory back pain (P<0.001), inadequate response to colchicine (P<0.05). Compared to 20 juvenile spondyloarthritis patients, familial Mediterranean fever related juvenile spondyloarthritis patients less often received non-steroidal anti-inflammatory drugs (P<0.01) and anti-tumor necrosis factor drugs (P<0.001). CONCLUSIONS: Familial Mediterranean fever may be associated with typical pattern of juvenile spondyloarthritis. These patients, with less response to colchicine, should be diagnosed earlier and treated as for jSpA. PMID- 29452307 TI - Impact of metabolic syndrome on clinical severity and long-term prognosis in patients with myocardial infarction with ST-segment elevation. AB - AIMS: The aim of this study is to evaluate the impact of metabolic syndrome (MetS) on clinical severity and long-term prognosis in patients with myocardial infarction with ST-segment elevation (STEMI). METHODS: We examined 507 patients with STEMI, who were admitted for primary percutaneous coronary intervention classified according to the presence of MetS using American Heart Association and the National Heart, Lung, and Blood Institute definition. After applying these criteria, the patients were categorized into groups as patients with MetS and without MetS. We compared baseline characteristics, clinical findings, and outcomes between these groups. During the 48-month follow-up, we collected data about major adverse cardiac events (MACE) and mortality. RESULTS: The MetS group comprised 217 patients with MetS (mean age = 60.71 +/- 11.52 years; 59 females), while the control group comprised 290 subjects (mean age = 57.50 +/- 10.95 years; 54 females). The patients with and without MetS had similar parameters of clinical severity of STEMI but differed in severe coronary artery disease. During the follow-up period, a significantly higher percentage of myocardial infarction (6.91% vs 2.06%) and new revascularization (16.59% vs 8.97%) was recorded in the MetS group. On multivariate analysis, MetS was independently associated with MACE (HR = 1.834, 95% CI = 1.162-2.896, p = 0.009) but not with mortality (HR = 1.603, 95% CI = 0.864-2.973, p = 0.134). Among cardiovascular events that compose MACE, MetS was associated with new revascularization (HR = 2.204, 95% CI = 1.273-3.815, p=0.005). CONCLUSION: The presence of MetS in patients with STEMI is an independent risk factor for MACE, and this syndrome is strongly associated with new revascularization.

PMID- 29452309 TI - Echocardiography for the management of patients with biventricular pacing: Possible roles in cardiac resynchronization therapy implementation. AB - Cardiac resynchronization therapy (CRT) is an established therapeutic option for the subset of patients with heart failure (HF), reduced ejection fraction (EF), and dyssynchrony evidenced by electrocardiography. Benefit from CRT has been proven in many clinical trials, yet a sizeable proportion of these patients with wide QRS do not respond to this intervention, despite the updated practice guidelines. Several echocardiographic indices, targeting mechanical rather than electrical dyssynchrony, have been suggested to address this issue, but research so far has not succeeded in providing a single and simple measurement with adequate sensitivity and specificity for identification of responders. While there is still ongoing research in this field, echocardiography proves helpful in other aspects of CRT implementation, such as site selection for left ventricular (LV) lead pacing and optimization of pacing parameters during follow-up visits.

AB - The genus Fritziana (Anura: Hemiphractidae) comprises six described species (F. goeldii, F. ohausi, F. fissilis, F. ulei, F. tonimi, and F. izecksohni) that are endemic to the Brazilian Atlantic Forest. Although the genus has been the subject of studies dealing with its taxonomy, phylogeny, and systematics, there is considerable evidence for cryptic diversity hidden among the species. The present study aims to understand the genetic diversity and phylogenetic relationships among the species of Fritziana, as well as the relationships among populations within species. We analyzed 107 individuals throughout the distribution of the genus using three mitochondrial gene fragments (12S, 16S, and COI) and two nuclear genes (RAG1 and SLC8A3). Our data indicated that the species diversity in the genus Fritziana is underestimated by the existence of at least three candidate species hidden amongst the group of species with a closed dorsal pouch (i.e. F. fissilis and F. ulei). We also found four species presenting geographical population structures and high genetic diversity, and thus require further investigations. In addition, we found that two candidate species show a new arrangement for the tRNA-Phe gene, unique in Anura so far. Based on our results, we suggest that the conservation status of the species, as well as the species diversity in the genus Fritziana, needs to be reviewed. PMID- 29452312 TI - Effects of Higher Versus Lower Threat Contexts on Pain-Related Visual Attention Biases: An Eye-Tracking Study of Chronic Pain. AB - : In this research, we examined effects of higher versus lower threat contexts on attention biases in more and less pain-fearful chronic pain subgroups via eye tracking methodology. Within a mixed chronic pain sample (69 women, 29 men), biases in orienting and maintenance of visual attention were assessed during the standardized image pair presentation phase (2,000 ms) of a modified visual dot probe task featuring painful-neutral (P-N) image pairs (lower threat context) and a parallel task in which these P-N pairs cued potential pain (higher threat context). Across both tasks, participants more often oriented toward, gazed longer at, and made more unique fixations upon pain images during P-N pair presentations. Although trait-based fear of pain was not related to any gaze bias index in either task, between task analyses indicated the sample reported more state fear, directed their initial gaze less often, and displayed longer overall gaze durations toward pain images in the higher threat context in which P-N trials signaled potential pain. Results supported the threat interpretation model premise that persons with chronic pain have difficulty disengaging from moderately threatening visual painful cues. PERSPECTIVE: Through integrating dot probe and impending pain task paradigms, we assessed effects of lower versus higher threat contexts on visual attention biases of persons with chronic pain via eye tracking. Under higher threat conditions featuring possible pain, state fear levels were elevated and maintenance of attention on painful depictions was more prolonged.

AB - OBJECTIVE: To explore whether the iliac wing influences L5 pedicle screw (PS) fixation and to propose methods to reduce such influence. METHODS: A total of 100 computed tomography scans (from 50 male and 50 female patients) of the lower lumbar region and pelvis were obtained and 3-dimensionally reconstructed. Cylinders with 6.5-mm diameters were drawn to simulate the different trajectories of L5 PS. The maximum lengths and lateral angles of trajectories, and the vertical distances from the inner edge of the iliac wing to these trajectories, were measured. RESULTS: The maximum lengths and lateral angles differed significantly among trajectories; the maximum length, but not the lateral angle, differed significantly between male and female subjects. The influence of the iliac wing was more significant in male than in female subjects. The iliac wing had a greater effect on screws implanted along the pedicle axis than on screws for which the trajectories commenced at Du's entry point and passed through the center of the pedicle. CONCLUSIONS: This study elucidates the influence of the iliac wing on L5 PS fixation. Careful attention is required when implanting PSs, especially in male patients. The combined use of Du's technique and a percutaneous method for PS implantation effectively reduces the influence of the iliac wing. To minimize the complications of PS fixation further, preoperative simulation of fixation for each patient is very important. PMID- 29452314 TI - Movement Disorders and Deep Brain Stimulation in the Middle East. AB - BACKGROUND: Deep brain stimulation (DBS) is a well-established neuromodulation therapy for advanced Parkinson disease, essential tremor and dystonia. In as much as this therapy is being developed in the Middle East, a better understanding of the incidence and prevalence of movement disorders, health care, and social framework is required for the region. METHODS: We reviewed current literature on the incidence and prevalence of various movement disorders in the Middle East amenable to DBS surgery. We also assessed recent efforts to develop DBS in the region. RESULTS: Available data on incidence and prevalence of movement disorders in the Middle East are old, inconclusive, and conflicting. We identify key areas such as cultural background, availability of accessible information, training, infrastructure, and public support groups in the region that may pose challenges. CONCLUSIONS: The Middle East is projected to be a growing market for neuromodulation. The available data on incidence and prevalence of movement disorders is from studies that were small, partial, and old, with inconsistent results, highlighting the need for newer, better-designed, and larger studies. DBS in the Middle East will need assessment of incidence and prevalence of movement disorders, existing challenges to its application, and focused efforts on key opportunities to foster development of DBS for this underserved region. This article is an attempt to identify and explore these challenges and propose solutions in anticipation. PMID- 29452315 TI - Technical Aspects of Awake Craniotomy with Mapping for Brain Tumors in a Limited Resource Setting. AB - BACKGROUND: Brain tumor surgery near or within eloquent regions is increasingly common and is associated with a high risk of neurologic injury. Awake craniotomy with mapping has been shown to be a valid method to preserve neurologic function and increase the extent of resection. However, the technique used varies greatly among centers. Most count on professionals such as neuropsychologists, speech therapists, neurophysiologists, or neurologists to help in intraoperative patient evaluation. We describe our technique with the sole participation of neurosurgeons and anesthesiologists. METHODS: A retrospective review of 19 patients who underwent awake craniotomies for brain tumors between January 2013 and February 2017 at a tertiary university hospital was performed. We sought to identify and describe the most critical stages involved in this surgery as well as show the complications associated with our technique. RESULTS: Preoperative preparation, positioning, anesthesia, brain mapping, resection, and management of seizures and pain were stages deemed relevant to the accomplishment of an awake craniotomy. Sixteen percent of the patients developed new postoperative deficit. Seizures occurred in 24%. None led to awake craniotomy failure. CONCLUSIONS: We provide a thorough description of the technique used in awake craniotomies with mapping used in our institution, where the intraoperative patient evaluation is carried out solely by neurosurgeons and anesthesiologists. The absence of other specialized personnel and equipment does not necessarily preclude successful mapping during awake craniotomy. We hope to provide helpful information for those who wish to offer function-guided tumor resection in their own centers. PMID- 29452316 TI - Endoscopic Neurosurgery: Surgeon Versus Machine. PMID- 29452317 TI - Minimally Invasive Alternative Approaches to Pterional Craniotomy: A Systematic Review of the Literature. AB - OBJECTIVE: Minimally invasive alternatives to the pterional craniotomy include the minipterional and the supraorbital craniotomy (SOC). The latter is performed via either an eyebrow or an eyelid skin incision. The purpose of this systematic review was to analyze the type and the incidence of approach-related complications of these so-called "keyhole craniotomies". METHODS: We review pertinent articles retrieved by search in the PubMed/Medline database. Inclusion criteria were all full-text articles, abstracts, and posters in English, up to 2016, reporting clinical results. RESULTS: A total of 105 articles containing data on 5837 surgeries performed via a minipterional or either of the 2 variants of the SOC met the eligibility criteria. Pain on mastication was the most commonly reported approach-related complication of the minipterional approach, and occurred in 7.5% of cases. Temporary palsy of the frontal branch of the facial nerve and temporary supraorbital hypesthesia were associated with the SOC eyebrow variant, and occurred in 6.5%, respectively in 3.6% of cases. Transient postoperative periorbital edema and transient ophthalmoparesis occurred in 36.8% and 17.4% of cases, respectively, when the SOC was performed via an eyelid skin incision. The risk of occurrence of the latter 2 complications was related to the removal of the orbital rim, which is an obligatory part of the SOC approach through the eyelid but optional with the SOC eyebrow variant. CONCLUSIONS: Each of the 3 keyhole approaches has a specific set and incidence of approach-related complications. It is essential to be aware of these complications to make the safest individual choice. PMID- 29452318 TI - Bone Metabolic Markers in the Clinical Assessment of Patients with Superior Semicircular Canal Dehiscence. AB - BACKGROUND: Superior semicircular canal dehiscence (SSCD) is a bony defect in the osseous shell of the petrous temporal bone. The pathophysiological association between osteoporosis and SSCD remains poorly understood. We investigated the relationship between bone metabolic markers and symptoms in patients with SSCD. METHODS: We collected patient demographics and clinical parameters for adult patients diagnosed with SSCD on high-resolution computed tomography scans. We used point-biserial correlation analysis to investigate the relationship between bone metabolic markers and symptoms in patients with SSCD. We compared clinical symptoms before and after surgical repair of SSCD through a middle fossa craniotomy using McNemar's test for paired comparisons of binary measures. RESULTS: We included a total of 99 patients (64 females and 35 males; average age 52 years; 118 surgeries). The level of serum calcium correlated with the need for a second surgery (rpb = -0.35, P = 0.001). Postoperative calcium supplementation negatively correlated with improvement in dizziness (rpb = -0.36, P = 0.01). The level of 25-hydroxyvitamin D correlated with preoperative hyperacusis (rpb = 0.98, P = 0.02) and postoperative autophony (rpb = 0.96, P = 0.04). Postoperative vitamin D supplementation positively correlated with hearing decline (rpb = 0.04, P = 0.04) The level of thyroid stimulating hormone correlated with preoperative autophony, amplification, and tinnitus (rpb = -0.71, rpb = -0.75, rpb = -0.70, all P < 0.001). CONCLUSIONS: Bone metabolic markers could be important in the clinical assessment of SSCD patients and could be potential targets for symptom management. PMID- 29452319 TI - "White Cord Syndrome" of Acute Hemiparesis After Posterior Cervical Decompression and Fusion for Chronic Cervical Stenosis. AB - BACKGROUND: "White cord syndrome" is a very rare condition thought to be due to acute reperfusion of chronically ischemic areas of the spinal cord. Its hallmark is the presence of intramedullary hyperintense signal on T2-weighted magnetic resonance imaging sequences in a patient with unexplained neurologic deficits following spinal cord decompression surgery. The syndrome is rare and has been reported previously in 2 patients following anterior cervical decompression and fusion. We report an additional case of this complication. CASE DESCRIPTION: A 68 year-old man developed acute left-sided hemiparesis after posterior cervical decompression and fusion for cervical spondylotic myelopathy. The patient improved with high-dose steroid therapy. CONCLUSIONS: The rare white cord syndrome following either anterior cervical decompression and fusion or posterior cervical decompression and fusion may be due to ischemic-reperfusion injury sustained by chronically compressed parts of the spinal cord. In previous reports, patients have improved following steroid therapy and acute rehabilitation. PMID- 29452320 TI - The Risk of Traumatic Brain Injury Occurring Among Patients with Parkinson Disease: A 14-Year Population-Based Study. AB - BACKGROUND: Previous studies have implicated traumatic brain injury (TBI) as a risk factor for Parkinson disease (PD). However, the incidence risk of new-onset TBI among patients with PD is not well established. This study investigated the contribution of PD to new-onset TBI associations. METHODS: The study selected 6076 patients with PD and using 1:2 propensity score matching 12,152 general population cohorts in a longitudinal population database in Taiwan. The Cox proportional hazard regression model was used to estimate the hazard ratio of TBI adjusted with the potential confounding factors. RESULTS: The incidence of TBI in patients with PD (2.57%) and compared cohorts (1.81%) was significantly different (P = 0.0007). Patients with PD had a higher risk of TBI (hazard ratio, 1.63; 95% confidence interval, 1.32-2.01) compared with the general population. Patients with PD with TBI incidence had a higher Charlson Comorbidity Index than did the general population with TBI (P < 0.0001). Fall is the major cause of TBI in patients with PD. CONCLUSIONS: This study shows that patients with PD have a high risk of TBI, and the major cause of TBI in patients with PD is fall. PMID- 29452321 TI - Hypoplastic Straight Sinus with Persistent Falcine Sinus in Adult with Sinus Pericranii. AB - Open magnetic resonance imaging of a 45-year-old man with panic disorder showed a sinus pericranii (SP). Examination of the scalp revealed a discolored scalp mass, and magnetic resonance venography displayed a hypoplastic straight sinus with persistent falcine sinus. SP is a venous anomaly consisting of a transosseous vascular channel connecting an intracranial sinus with subgaleal veins. High venous pressure in the late embryonic stage, as with a hypoplastic straight sinus, has been hypothesized to predispose affected individuals to develop other venous anomalies (i.e., falcine sinus). Because there is no major venous outflow through this accessory SP in an asymptomatic adult, no intervention was recommended for our patient. PMID- 29452322 TI - End-Stage Liver Disease in Patients with Intracranial Hemorrhage Is Associated with Increased Mortality: A Cohort Study. AB - OBJECTIVE: To determine if end-stage liver disease (ESLD) in patients with intracranial hemorrhage (ICH) is associated with increased mortality. METHODS: This single-center, retrospective cohort study included 53 patients (33 in ESLD cohort and 20 in non-ESLD cohort) who received neurosurgical care between 2006 and 2017. ESLD was defined clinically as severely impaired liver function and at least 1 major complication of liver failure. The primary outcome was mortality. RESULTS: Overall, in-hospital, and 30-day mortality rates were higher in the ESLD cohort versus the non-ESLD cohort (79 vs. 30%, 79 vs. 20%, and 64 vs. 25%, all P <= 0.01). We identified a significant difference in overall survival between ESLD and non-ESLD cohorts on Kaplan-Meier analysis (P = 0.004 with log-rank and Wilcoxon tests). Odds of overall, in-hospital, and 30-day mortality in the ESLD cohort were 8.67 (95% confidence interval [CI], 2.44-30.84), 14.86 (95% CI, 3.75 58.90), and 5.25 (95% CI, 1.53-18.08). Other predictors of overall mortality included primary admission diagnosis of liver disease (odds ratio [OR] = 9.60; 95% CI, 3.75-58.90), higher Child-Pugh (OR = 1.64; 95% CI, 2.66-34.67) and Model for End-Stage Liver Disease (OR = 1.12; 95% CI, 1.04-1.20) scores, lower Glasgow Coma Scale score (OR = 0.73; 95% CI, 0.61-0.88), ICH that developed in the hospital (OR = 4.11; 95% CI, 1.21-13.98), and intraparenchymal hemorrhage (OR = 9.23; 95% CI, 1.72-49.56). CONCLUSIONS: ESLD in patients with ICH is associated with increased mortality. PMID- 29452323 TI - Burr Hole Surgery for Chronic Subdural Hematoma with Extensive Scalp Burn. AB - BACKGROUND: Neurosurgical intervention for a patient with an extensive scalp burn is rare, but it may be associated with a high risk of surgical site infection. CASE DESCRIPTION: An 80-year-old man had a severe and extensive scalp burn. A chronic subdural hematoma (CSDH) was observed on a computed tomographic view of the head, performed for the assessment of bacteremia during treatment in the intensive care unit. To evaluate whether the CSDH might underlie the patient's prolonged fever and sepsis, we urgently evacuated the hematoma using 1 burr hole. The surgery was uneventful. We made a skin incision through the deep burn wounds covering the right temporal muscle. We removed necrotic tissue from scalp burns continuously to avoid wound complications and intracranial infection. CONCLUSIONS: Temporal muscle with a constant blood supply served as an effective tissue for surgical wound closure. By use of this multidisciplinary approach, the CSDH resolved completely, and surgical wound complications were avoided. PMID- 29452324 TI - Microsurgical Clipping of Intracranial Aneurysms Assisted by Neurophysiological Monitoring, Microvascular Flow Probe, and ICG-VA: Outcomes and Intraoperative Data on a Multimodal Strategy. AB - OBJECTIVE: The aim of this study is to report data on a multimodal monitoring strategy based on the intraoperative use of neurophysiological monitoring, flowmetry by microflow probe, and intraoperative indocyanine green video angiography (ICG-VA) during microsurgical clipping of intracranial aneurysms. METHODS: This retrospective analysis was performed on 85 consecutive patients undergoing clipping of 96 intracranial aneurysms with the present monitoring strategy. Patient outcomes were evaluated by assessing rate of aneurysm exclusion and postoperative occurrence of ischemic injury. Intraoperative data for the strategy in addition to changes in each monitoring technique depending on aneurysm features were reported. RESULTS: Complete aneurysm exclusion was achieved in 98.9% of cases. Postoperative symptomatic ischemic injury was recorded in 2.08% aneurysms. Clip repositioning occurred in 40.6% of cases: because of motor evoked potential (MEP) decrease in 9.3%, flowmetry in 22.91%, and ICG-VA in 8.3% of treated aneurysms (1.05% after ICG injection, 7.4% after the squeezing maneuver). The role of each technique differed according to aneurysm features; flowmetry alterations occurred more frequently in distal than in proximal aneurysms (P = 0.0001) and in atherosclerotic aneurysms (P = 0.0001). MEP impairment occurred more often in proximal aneurysms (P < 0.05). ICG-VA disclosed remnant aneurysms mainly in atherosclerotic aneurysms (P < 0.05); only one false negative remnant neck was recorded with a negative predictive value of 98.8%. CONCLUSIONS: Microsurgical clipping assisted by a multimodal monitoring strategy achieved a high rate of aneurysm exclusion with low morbidity in our series. Our data show that the 3 techniques used in our strategy were complementary and that a monitoring strategy can be tailored to aneurysm features. PMID- 29452325 TI - Treatment of Wide-Neck Bifurcation Aneurysm Using "WEB Device Waffle Cone Technique". AB - BACKGROUND: The endovascular treatment of wide-neck bifurcation aneurysms can be challenging and often requires the use of adjunctive techniques and devices. METHODS: We report our first experience of using a waffle-cone technique adapted to the Woven Endoluminal Bridge (WEB) device in a large-neck basilar tip aneurysm, suitable in cases where the use of Y stenting or other techniques is limited due to anatomic restrictions. RESULTS: The procedure was complete, and angiographic occlusion of the aneurysm was achieved 24 hours post treatment, as confirmed by digital subtraction angiography. No complications occurred. CONCLUSIONS: The case reported here was not suitable for Y stenting or deployment of the WEB device alone, due to the small caliber of both posterior cerebral arteries and their origin at the neck level. The main advantage of this technique is that both devices have a controlled detachment system and are fully independent. To our knowledge, this technique has not been reported previously and this modality of treatment has never been described in the literature. PMID- 29452326 TI - Awake Microvascular Decompression for Trigeminal Neuralgia: Concept and Initial Results. AB - BACKGROUND: In this initial series, we evaluated the use of microvascular decompression (MVD) under an awake anesthesia protocol ("awake" MVD) to assess whether intraoperative pain evaluation can identify and mitigate insufficient decompression of the trigeminal nerve, improving surgical outcomes, and possibly expand the indications of MVD in patients with comorbidities that would preclude the use of general endotracheal anesthesia (GEA). METHODS: An Institutional Review Board-approved prospective study of 10 consecutive adults who underwent MVD for trigeminal neuralgia (TN) was conducted. The primary outcome measure was postoperative TN pain quantified on the Barrow Neurological Institute (BNI) Pain Severity Scale. RESULTS: The median patient age was 65.5 years, with a female:male ratio of 6:4. All 10 patients tolerated the procedure well and did not require GEA intraoperatively or postoperatively. Nine patients had a successful surgical outcome (BNI score I, n = 5; BNI score II, n = 4). One patient did not have pain relief (BNI score IV). This same patient also developed a pseudomeningocele, which was the sole surgical complication observed in this series. One patient experienced recurrence of pain at 11 months, with BNI score increasing from I to II. The median duration of follow-up was 16.5 months. Two patients did not experienced resolution of evoked pain during intraoperative awake testing following decompression. Further intraoperative exploration revealed secondary offending vessels that were subsequently decompressed, leading to resolution of pain. CONCLUSIONS: Intraoperative awake testing for treatment efficacy may increase the success rate of MVD by rapidly identifying and mitigating insufficient cranial nerve V decompression. PMID- 29452327 TI - Effect and Feasibility of Endoscopic Surgery in Spontaneous Intracerebral Hemorrhage: A Systematic Review and Meta-Analysis. AB - BACKGROUND: Spontaneous intracerebral hemorrhage remains a major cause of death and dependence. Endoscopic surgery (ES) is potential to improve outcomes, but a consensus on the superiority of ES has not been achieved. We conducted a systematic review to clarify the effect of ES in spontaneous intracerebral hemorrhage and compare it with other treatment options (craniotomy, conservation, and stereotactic aspiration [SA]). METHODS: We performed this review based on the Preferred Reporting Items for Systematic review and Meta-Analysis. The subgroup analyses were stratified by study type, location, hematoma volume, interval to treatment, follow-up time, and stereotactic frame assistance. RESULTS: A total of 18 studies were included containing 1213 patients, most of whom harbored a hematoma greater than 50 mL. Compared with craniotomy and conservation, ES significantly reduced the mortality (P < 0.0001), poor outcomes (P < 0.00001), rebleeding (P = 0.0009), and pneumonia (P < 0.00001). In the subgroup analyses, late surgery (<48 hours) benefited more from ES than early surgery (<24 hours). The study location, hematoma volume, and stereotactic frame assistance insignificantly influenced the therapeutic effect of ES. Comparing ES and SA, we found that differences in mortality, poor outcomes, and rebleeding were insignificant, but ES had a greater evacuation rate and SA had shorter operative times. CONCLUSIONS: ES achieves a better performance than craniotomy and conservation in terms of reducing mortality, dependence, and specific complications. Despite being similarly effective in improving functional outcomes, ES and SA have respective advantages. ES is a feasible alternation to craniotomy and conservation, and the comparison between ES and SA warrants further study. PMID- 29452328 TI - Louis Victor Leborgne ("Tan"). AB - Louis Victor Leborgne was a patient of Paul Broca. "Monsieur Leborgne," as Broca would call him, was also known around in the hospital by the nickname "Tan." His neurologic condition left him with difficulty in speaking, and he could only speak the word "Tan." Leborgne spent nearly half of his entire life in the hospital. He was initially admitted into the psychiatry division of the hospital and was later transferred under the care of Broca toward the end of his life. The story of the Leborgne sits in the crossroads of human thoughts that led to the discovery of cerebral localization. It is the objective of this study to describe the circumstances associated with this patient, which led the great thinkers of that time to discover the language localization in the cerebral cortex. Leborgne's condition was the cornerstone in the evolution of this discovery. More than 150 years have passed since the death of Leborgne, yet Leborgne's brain continues to attract researchers investigating the mysteries of human speech. PMID- 29452329 TI - Frontal Sinus Osteoma Accompanied by Intracranial Mucocele and Local Hyperostosis Frontalis Interna. AB - Frontal sinus osteoma accompanied by intracranial mucocele and local hyperostosis frontalis interna has never been reported. A 47-year-old woman presented with a 3 month history of intermittent headache. Physical examination revealed no neurologic abnormality. Contrasted magnetic resonance imaging showed a frontal heterogeneously enhanced lesion with adjacent nonenhanced cyst. Computed tomography showed a bone density mass, which was accompanied by local hyperostosis frontalis interna, which filled the left frontal sinus and extended intracranially. The patient underwent a left frontobasal craniotomy. Both the osseous mass and cyst capsule were removed totally via a frontal craniotomy, followed by skull base reconstruction. The postoperative course was uneventful. The final pathologic diagnosis was osteoma and mucocele. PMID- 29452330 TI - Atypical Teratoid/Rhabdoid Tumor After In Vitro Fertilization: Illustrative Case Report and Systematic Literature Review. AB - OBJECTIVE: In vitro fertilization (IVF) is increasingly used for the treatment of infertile couples worldwide. The association between IVF and cancer risk in offspring is conflicting. We present a case of atypical teratoid/rhabdoid tumor (AT/RT) in a girl conceived by IVF and present results of systematic review of literature of primary intracranial neoplasms diagnosed in children conceived by IVF. METHODS: A systematic review of literature was conducted on April 12, 2017, to identify previously published reports of intracranial brain tumors in patients conceived after IVF. RESULTS: A 21-month-old girl born after IVF and uneventful pregnancy presented with progressive nausea, vomiting, irritability, and right side weakness. Magnetic resonance imaging demonstrated large heterogeneous contrast enhancing left frontotemporoparietal tumor. The operation was aborted due to asystole after subtotal tumor removal. The patient passed away on postoperative day 3. Histologic examination demonstrated AT/RT. We identified 7 previously published case reports of intracranial neoplasms in children conceived by IVF. Patient age at brain tumor diagnosis ranged from 31st week of gestation to 3 years of age. The most common histological diagnosis was AT/RT (3 cases), followed by glioblastoma multiforme, gliosarcoma, medulloblastoma, craniopharyngioma, and choroid plexus papilloma. Three of five operated patients died during perioperative period. Outcomes were dismal in 7 patients. CONCLUSIONS: IVF-associated brain tumors are usually malignant and associated with high mortality. Future studies investigating possible causal relationship between IVF and brain tumor risk are encouraged. PMID- 29452331 TI - Reproducibility of sub-acromial impingement tests, including a new clinical manoeuver. AB - BACKGROUND: The Neer, Hawkins, and Yocum clinical tests detect sub-acromial impingement as a pathogenic process of degenerative rotator cuff disease. Their reproducibility has been little investigated. OBJECTIVES: We tested the reproducibility of the Neer, Hawkins, and Yocum clinical tests for detecting this sub-acromial impingement and also an original clinical manoeuver, the countertest with elevation with lateral rotation (CELR), which is a test of sub-acromial impingement. METHODS: Patients with shoulder pain due to degenerative rotator cuff disease were prospectively included. They were assessed with the Neer, Hawkins and Yocum tests as well as the CELR twice at a 1 week interval. Intra- and inter-observer reproducibility was assessed by percentage agreement and the kappa coefficient of concordance with 95% confidence intervals (CIs). Concordance was poor with kappa <=0.4, moderate >0.4, and good >0.61. It was considered suitable for clinical use with kappa >0.4. RESULTS: We included 34 patients (mean [SD] age 60 [11] years; 26 females). For intra-observer reproducibility, agreement was 80% to 88%. By the kappa coefficient, intra-observer reproducibility was poor for the Neer test and moderate for the Hawkins test (0.56 [95% CI 0;0.9]) and Yocum test (0.48 [0;0.8]) and CELR (0.6 [0.2;0.9]). For inter-observer reproducibility, agreement was 73% to 88%. By the kappa coefficient, inter-observer reproducibility was poor for the Yocum test, moderate for the Hawkins test (0.54 [0.2;0.8]) and CELR (0.58 [0.2;0.8]), and good for the Neer test (0.64 [0.2;0.9]). CONCLUSION: The Hawkins test and CELR had a balanced profile of reproducibility suitable for clinical practice. We underline the potential interest of CELR, an original manoeuver.

PMID- 29452333 TI - Male requires a higher median target effect-site concentration of propofol for I gel placement when combined with dexmedetomidine. AB - OBJECTIVE: The supraglottic airway device (SAD) can be used for airway management of spontaneous breathing patients, and propofol is commonly applied for the SAD placement. This study was designed to assess the effect of gender on median target effect-site concentration (Ce50) of propofol for I-gel placement when combined with dexmedetomidine. MATERIAL AND METHOD: 19 males and 18 females, aged 18 to 59 and undergoing elective surgery, were enrolled. After intravenous infusion of dexmedetomidine 1.0MUg/kg over 10min followed by continuous infusion of 0.4MUg/kg/h, target-controlled infusion of propofol under Marsh model was started and the initial Ce of propofol was set at 4.79MUg/mL and 4.35MUg/mL in the male and female patients, respectively. The I-gel was inserted when the Ce of propofol reached the pre-set concentration and bispectral index value was less than 60. The Ce of propofol required for I-gel placement was determined by the Dixon up-and-down method. RESULTS: The Ce50 (95% confidence interval) of propofol required for I-gel placement were 4.082MUg/mL (3.798-4.332MUg/mL) and 3.509MUg/mL (3.266-3.749MUg/mL) in male and female patients, respectively, with a significantly higher Ce50 in males. CONCLUSION: When combined with dexmedetomidine, males require a higher Ce50 of propofol for I-gel placement compared to females. PMID- 29452334 TI - SEED 2: a user-friendly platform for amplicon high-throughput sequencing data analyses. AB - Motivation: Modern molecular methods have increased our ability to describe microbial communities. Along with the advances brought by new sequencing technologies, we now require intensive computational resources to make sense of the large numbers of sequences continuously produced. The software developed by the scientific community to address this demand, although very useful, require experience of the command-line environment, extensive training and have steep learning curves, limiting their use. We created SEED 2, a graphical user interface for handling high-throughput amplicon-sequencing data under Windows operating systems. Results: SEED 2 is the only sequence visualizer that empowers users with tools to handle amplicon-sequencing data of microbial community markers. It is suitable for any marker genes sequences obtained through Illumina, IonTorrent or Sanger sequencing. SEED 2 allows the user to process raw sequencing data, identify specific taxa, produce of OTU-tables, create sequence alignments and construct phylogenetic trees. Standard dual core laptops with 8 GB of RAM can handle ca. 8 million of Illumina PE 300 bp sequences, ca. 4 GB of data. Availability and implementation: SEED 2 was implemented in Object Pascal and uses internal functions and external software for amplicon data processing. SEED 2 is a freeware software, available at http://www.biomed.cas.cz/mbu/lbwrf/seed/ as a self-contained file, including all the dependencies, and does not require installation. Supplementary data contain a comprehensive list of supported functions. Supplementary information: Supplementary data are available at Bioinformatics online. PMID- 29452335 TI - Change in cardiometabolic risk among blacks, whites and Hispanics: findings from the Health and Retirement Study. AB - Background: Blacks experience greater multi-system physiological dysregulation, or cumulative biological risk, which is associated with poor cardiometabolic health and mortality. In this study, we assess race differences in change in risk over four years among older whites, blacks and Hispanics. Method: We examined race differences in 4-year change in individual biomarkers and a cumulative measure of risk-cardiometabolic risk (CMR)-using data for each respondent from two waves of the Health and Retirement Study's biomarker assessment (n=5,512). CMR is a count of high-risk cardiovascular and metabolic biomarkers. We estimated mean CMR at baseline and follow-up by race/ethnicity, and used logistic regression to determine whether race differences exist in 4-year transitions between high- and low-risk states for individual biomarkers. Results: Blacks had higher baseline CMR than whites and Hispanics and experienced an increase in risk over four years; conversely, CMR decreased among whites and Hispanics. Blacks were more likely to develop high-risk pulse pressure and high-risk hemoglobin A1c, which contributed to increases in CMR. Whites and Hispanics were more likely to become low-risk on C-reactive protein and HDL cholesterol which contributed to declines in CMR. Race differences in transitions between risk states remained after controlling for social, behavioral and health care related factors. However, the racial patterning of these differences was influenced by disease diagnosis and medication use. Conclusions: We show that the cardiometabolic health of older blacks worsens as they age both absolutely and relative to that of whites and Hispanics because of poor blood pressure control and diabetes prevention.

PMID- 29452336 TI - Invited Commentary: Male Reproductive System Congenital Malformations and the Risk of Autism Spectrum Disorder. AB - Autism spectrum disorder (ASD) is a prevalent developmental disorder. Studies indicate that while ASD etiology has a genetic component, the risk is polygenic, with gene-environment interactions being likely. The prenatal period is a critical exposure window for nongenetic risk factors. Previous studies have found positive associations between congenital malformations (all types) and ASD; a few also found specific associations between genitourinary system malformations and ASD; and one study found an association between hypospadias and ASD. In the accompanying article, Rotem et al. (Am J Epidemiol. 2018;187(4):656-663) describe how they conducted a comprehensive analysis focusing on the shared risk of ASD with hypospadias or cryptorchidism, using existing data from a large Israeli health services system, which afforded several advantages because of the large sample size and low attrition of the patient population. The authors conducted a careful analysis, including sensitivity analyses, to account for risk factor and case misclassifications that might have occurred had they relied solely on preexisting diagnostic codes to define exposures and outcome. They observed positive associations between both hypospadias and cryptorchidism and ASD that were independent of numerous sociodemographic and pregnancy health factors. This study advances our understanding of ASD etiology and illustrates how existing data might be used to assess some ASD risk factors.

Hypospadias (abnormal positioning of the urethral opening) and cryptorchidism (undescended testes) are 2 relatively common male birth defects that are strongly associated with prenatal androgen deficiencies. Having either disorder is a proxy indicator of atypical gestational androgen exposure, yet the association between these disorders and autism has not been extensively studied. We analyzed male singleton live births (n = 224,598) occurring from January 1, 1999, through December 31, 2013, in a large Israeli health-care organization. Boys with autism, cryptorchidism, and hypospadias were identified via International Classification of Diseases, Ninth Revision, codes, with further verification of autism case status by review of medical records. In multivariable-adjusted analyses, the odds ratio for ASD among boys with either condition was 1.62 (95% confidence interval (CI): 1.44, 1.82). The odds ratio for boys with cryptorchidism only was 1.55 (95% CI: 1.34, 1.78), and that for boys with hypospadias only was 1.65 (95% CI: 1.38, 1.98). ASD risk was not elevated among unaffected brothers of hypospadias or cryptorchidism cases, despite familial aggregation of all 3 conditions, providing some indication for the possibility of pregnancy-specific risk factors driving the observed associations. Results suggest that in-utero hypoandrogenicity could play a role in ASD etiology. PMID- 29452341 TI - Betadine and Breast Implants. AB - In the fourth quarter of 2017, the US FDA reviewed and approved a request by one of the breast implant manufacturers for a change in the Directions for Use (DFU) that removed warnings regarding the use of Betadine (povidone-iodine [PI] 10% solution, 1% available iodine [Purdue Frederick Company, Stamford, CT], also available in generic formulations [Aplicare, Inc., Meriden, CT]). Previously, in 2000, there were concerns by the FDA that PI would degrade the silicone elastomer shell. This change in the DFU represents an important advance that will benefit patients through the permitted use of PI to reduce the risk of bacterial contamination of implant surfaces. What was formerly an off-label practice can be openly practiced by plastic surgeons as an anti-infective and biofilm-mitigation strategy. PI has an ideal spectrum effect for gram-positive and gram-negative organisms. Gram-positive organisms have been linked to capsular contracture and gram-negative Ralstonia picketti to breast implant-associated anaplastic large cell lymphoma (BIA-ALCL). R picketti is resistant to aminoglycoside antibiotics, but it is susceptible to at least a 50% solution of PI. We believe that the strategy of antisepsis and biofilm mitigation is an integral part of a contemporary approach for breast augmentation. This is beneficial regarding reduction of the risk of surgical infection, capsular contracture, and BIA-ALCL. Outcome data so far indicate that antibiotics/anti-infectives seem to reduce the incidence of these adverse events that lead to reoperation and increased costs. It behooves plastic surgeons to take all actionable steps that enhance the quality of breast implant outcomes and reduce the rate of reoperation. PMID- 29452342 TI - Neurofilament light chain and oligoclonal bands are prognostic biomarkers in radiologically isolated syndrome. AB - The prognostic role of cerebrospinal fluid molecular biomarkers determined in early pathogenic stages of multiple sclerosis has yet to be defined. In the present study, we aimed to investigate the prognostic value of chitinase 3 like 1 (CHI3L1), neurofilament light chain, and oligoclonal bands for conversion to clinically isolated syndrome and to multiple sclerosis in 75 patients with radiologically isolated syndrome. Cerebrospinal fluid levels of CHI3L1 and neurofilament light chain were measured by enzyme-linked immunosorbent assay. Uni and multivariable Cox regression models including as covariates age at diagnosis of radiologically isolated syndrome, number of brain lesions, sex and treatment were used to investigate associations between cerebrospinal fluid CHI3L1 and neurofilament light chain levels and time to conversion to clinically isolated syndrome and multiple sclerosis. Neurofilament light chain levels and oligoclonal bands were independent risk factors for the development of clinically isolated syndrome (hazard ratio = 1.02, P = 0.019, and hazard ratio = 14.7, P = 0.012, respectively) and multiple sclerosis (hazard ratio = 1.03, P = 0.003, and hazard ratio = 8.9, P = 0.046, respectively). The best cut-off to classify cerebrospinal fluid neurofilament light chain levels into high and low was 619 ng/l, and high neurofilament light chain levels were associated with a trend to shorter time to clinically isolated syndrome (P = 0.079) and significant shorter time to multiple sclerosis (P = 0.017). Similarly, patients with radiologically isolated syndrome presenting positive oligoclonal bands converted faster to clinically isolated syndrome and multiple sclerosis (P = 0.005 and P = 0.008, respectively). The effects of high neurofilament light chain levels shortening time to clinically isolated syndrome and multiple sclerosis were more pronounced in radiologically isolated syndrome patients with >=37 years compared to younger patients. Cerebrospinal fluid CHI3L1 levels did not influence conversion to clinically isolated syndrome and multiple sclerosis in radiologically isolated syndrome patients. Overall, these findings suggest that cerebrospinal neurofilament light chain levels and oligoclonal bands are independent predictors of clinical conversion in patients with radiologically isolated syndrome. The association with a faster development of multiple sclerosis reinforces the importance of cerebrospinal fluid analysis in patients with radiologically isolated syndrome. PMID- 29452343 TI - Height-Based Equations Can Improve the Diagnosis of Elevated Blood Pressure in Children. AB - Background: High blood pressure (BP) is usually underdiagnosed in children and adolescents, particularly due to its complex diagnosis process. This study describes novel height-based equations for the detection of BP disorders (BP > 90th percentile) and compares the accuracy of this approach with previously described screening methods to identify BP disorders. Methods: Height-based equations were built using the 90th percentile values for systolic and diastolic BP and respective height values from the current guideline of high-BP management in children. This guideline was also used as the gold standard method for identification of BP disorders. The equations were tested in Brazilian (n = 2,936) and American (n = 6,541) populations of children with 8-13 years old. Results: The obtained equations were 70 + 0.3 * height (in cm) for systolic BP and 35 + 0.25 * height (in cm) for diastolic BP. The new equations presented sensitivity and negative predictive value of near 100% and specificity > 91% and showed higher specificity and positive predictive value when compared with other screening tools. Importantly, height-based equations had greater agreement (kappa coefficient = 0.75-0.81) with the gold standard method than the other methods (kappa coefficient = 0.53-0.73). Further analysis showed that alternative height based equations designed to identify hypertension (BP >= 95th percentile) also showed superior performance (kappa coefficient = 0.89-0.92) compared with other screening methods (kappa coefficient = 0.43-0.85). Conclusions: These findings suggest that the use of height-based equations may be a simple and feasible approach to improve the detection of high BP in the pediatric population. PMID- 29452344 TI - Overexpression of BLM promotes DNA damage and increased sensitivity to platinum salts in triple-negative breast and serous ovarian cancers. AB - Background: Platinum-based therapy is an effective treatment for a subset of triple-negative breast cancer and ovarian cancer patients. In order to increase response rate and decrease unnecessary use, robust biomarkers that predict response to therapy are needed. Patients and methods: We performed an integrated genomic approach combining differential analysis of gene expression and DNA copy number in sensitive compared with resistant triple-negative breast cancers in two independent neoadjuvant cisplatin-treated cohorts. Functional relevance of significant hits was investigated in vitro by overexpression, knockdown and targeted inhibitor treatment. Results: We identified two genes, the Bloom helicase (BLM) and Fanconi anemia complementation group I (FANCI), that have both increased DNA copy number and gene expression in the platinum-sensitive cases. Increased level of expression of these two genes was also associated with platinum but not with taxane response in ovarian cancer. As a functional validation, we found that overexpression of BLM promotes DNA damage and induces sensitivity to cisplatin but has no effect on paclitaxel sensitivity. Conclusions: A biomarker based on the expression levels of the BLM and FANCI genes is a potential predictor of platinum sensitivity in triple-negative breast cancer and ovarian cancer. PMID- 29452345 TI - Daily Biopsy Diagnosis in Surgical Pathology: Concordance Between Light Microscopy and Whole-Slide Imaging in Real-Life Conditions. AB - Objectives: The current challenge for the various digital whole-slide imaging (WSI) systems is to be definitively validated for diagnostic purposes. We designed a concordance study between glass slide and digital slide diagnosis in real-life conditions, coupled with an ergonomic study. Methods: Three senior pathologists evaluated, first in glass slides and then in digital slides, 119 biopsy cases, including 749 slides, with 332 H&E saffron stains and 417 additional techniques, mainly immunohistochemistry. Results: All digital slides, including specially stained slides, were interpretable. Concordance between glass slides and digital slides was observed in 87.4% of cases. Minor discordances were observed in 12 (10.1%) cases and major discordances, with therapeutic impact, in three (2.5%), including one related to WSI. The satisfaction of participants was high and increased with time. Conclusions: Our study confirms the feasibility and accuracy of WSI diagnosis, even for cases having multiple samples and requiring special staining techniques, such as immunohistochemistry and in situ hybridization.

PMID- 29452346 TI - Beyond second-line therapy in patients with metastatic colorectal cancer: a systematic review. AB - Background: The optimal chemotherapeutic regimen for use beyond the second line for patients with metastatic colorectal cancer (mCRC) remains unclear. Materials and methods: We systematically searched the Cochrane Database of Systematic Reviews, EMBASE and Medline for records published between January 2002 and May 2017, and cancer congress databases for records published between January 2014 and June 2017. Eligible studies evaluated the efficacy, safety and patient reported outcomes of monotherapies or combination therapies at any dose and number of treatment cycles for use beyond the second line in patients with mCRC. Studies were assessed for design and quality, and a qualitative data synthesis was conducted to understand the impact of treatment on overall survival and other relevant cancer-related outcomes. Results: The search yielded 938 references of which 68 were included for qualitative synthesis. There was limited evidence to support rechallenge with chemotherapy, targeted therapy or both. Compared with placebo, an overall survival benefit for trifluridine/tipiracil (also known as TAS-102) or regorafenib has been shown for patients previously treated with conventional chemotherapy and targeted therapy. There was no evidence to suggest a difference in efficacy between these treatments. Patient choice and quality of life at this stage of treatment should also be considered when choosing an appropriate therapy. Conclusions: These findings support the introduction of an approved agent such as trifluridine/tipiracil or regorafenib beyond the second line before any rechallenge in patients with mCRC who have failed second-line treatment. PMID- 29452348 TI - Non-invasive screening for coronary artery disease in asymptomatic diabetic patients: a systematic review and meta-analysis of randomised controlled trials. AB - It is unclear whether non-invasive screening of asymptomatic diabetic patients for coronary artery disease (CAD) may improve cardiac outcomes. Thus, we performed a systematic literature review and meta-analysis of randomised controlled trials (RCT's) on this topic. We searched appropriate RCT's in five online databases (PubMed/MEDLINE, Cochrane Library, Embase, Scopus, and Web of Science) from January 2000 to November 2017 and in 41 recent reviews. Two investigators independently extracted and assessed study data using standardised forms. Additional unpublished data were obtained from trial authors. The primary endpoint 'any cardiac event' was a composite of cardiac death, non-fatal myocardial infarction (MI), unstable angina (UA), or heart failure (HF) hospitalisation. We performed a meta-analysis of relative risks (RRs) with 95% confidence intervals (CI) using the Mantel-Haenszel method. We included five RCT's with 3299 patients, of which 189 (5.7%) experienced any cardiac event on follow-up (weighted mean 4.1 years). Non-invasive CAD screening significantly reduced any cardiac event by 27% [RR 0.73 (95% CI 0.55-0.97), P = 0.028, number needed to screen 56]. This result was driven by important, albeit non-significant decreases in non-fatal MI [RR 0.65 (95% CI 0.41-1.02), P = 0.062] and HF hospitalisation [RR 0.61 (95% CI 0.33-1.10), P = 0.100]. Non-invasive CAD screening did not significantly affect cardiac death [RR 0.92 (95% CI 0.53-1.60), P = 0.77] and UA [RR 0.73 (95% CI 0.41-1.31), P = 0.29]. Compared with the standard care, non-invasive CAD screening reduced cardiac events by 27% in asymptomatic diabetic patients, largely through reductions in non-fatal MIs, and HF hospitalisations. The present results justify larger, appropriately powered trials to potentially revisit current recommendations. PMID- 29452349 TI - Non-genomic effects of nuclear receptors: insights from the anucleate platelet. AB - Nuclear receptors (NRs) have the ability to elicit two different kinds of responses, genomic and non-genomic. Although genomic responses control gene expression by influencing the rate of transcription, non-genomic effects occur rapidly and independently of transcriptional regulation. Due to their anucleate nature and mechanistically well-characterized and rapid responses, platelets provide a model system for the study of any non-genomic effects of the NRs. Several NRs have been found to be present in human platelets, and multiple NR agonists have been shown to elicit anti-platelet effects by a variety of mechanisms. The non-genomic functions of NRs vary, including the regulation of kinase and phosphatase activity, ion channel function, intracellular calcium levels, and production of second messengers. Recently, the characterization of mechanisms and identification of novel binding partners of NRs have further strengthened the prospects of developing their ligands into potential therapeutics that offer cardio-protective properties in addition to their other defined genomic effects. PMID- 29452350 TI - Extra-virgin olive oil contains a metabolo-epigenetic inhibitor of cancer stem cells. AB - Targeting tumor-initiating, drug-resistant populations of cancer stem cells (CSC) with phytochemicals is a novel paradigm for cancer prevention and treatment. We herein employed a phenotypic drug discovery approach coupled to mechanism-of action profiling and target deconvolution to identify phenolic components of extra virgin olive oil (EVOO) capable of suppressing the functional traits of CSC in breast cancer (BC). In vitro screening revealed that the secoiridoid decarboxymethyl oleuropein aglycone (DOA) could selectively target subpopulations of epithelial-like, aldehyde dehydrogenase (ALDH)-positive and mesenchymal-like, CD44+CD24-/low CSC. DOA could potently block the formation of multicellular tumorspheres generated from single-founder stem-like cells in a panel of genetically diverse BC models. Pretreatment of BC populations with noncytotoxic doses of DOA dramatically reduced subsequent tumor-forming capacity in vivo. Mice orthotopically injected with CSC-enriched BC-cell populations pretreated with DOA remained tumor-free for several months. Phenotype microarray-based screening pointed to a synergistic interaction of DOA with the mTOR inhibitor rapamycin and the DNA methyltransferase (DNMT) inhibitor 5-azacytidine. In silico computational studies indicated that DOA binds and inhibits the ATP-binding kinase domain site of mTOR and the S-adenosyl-l-methionine (SAM) cofactor-binding pocket of DNMTs. FRET-based Z-LYTETM and AlphaScreen-based in vitro assays confirmed the ability of DOA to function as an ATP-competitive mTOR inhibitor and to block the SAM dependent methylation activity of DNMTs. Our systematic in vitro, in vivo and in silico approaches establish the phenol-conjugated oleoside DOA as a dual mTOR/DNMT inhibitor naturally occurring in EVOO that functionally suppresses CSC like states responsible for maintaining tumor-initiating cell properties within BC populations. PMID- 29452351 TI - Impact of treatment delay on mortality in ST-segment elevation myocardial infarction (STEMI) patients presenting with and without haemodynamic instability: results from the German prospective, multicentre FITT-STEMI trial. AB - Aims: The aim of this study was to investigate the effect of contact-to-balloon time on mortality in ST-segment elevation myocardial infarction (STEMI) patients with and without haemodynamic instability. Methods and results: Using data from the prospective, multicentre Feedback Intervention and Treatment Times in ST Elevation Myocardial Infarction (FITT-STEMI) trial, we assessed the prognostic relevance of first medical contact-to-balloon time in n = 12 675 STEMI patients who used emergency medical service transportation and were treated with primary percutaneous coronary intervention (PCI). Patients were stratified by cardiogenic shock (CS) and out-of-hospital cardiac arrest (OHCA). For patients treated within 60 to 180 min from the first medical contact, we found a nearly linear relationship between contact-to-balloon times and mortality in all four STEMI groups. In CS patients with no OHCA, every 10-min treatment delay resulted in 3.31 additional deaths in 100 PCI-treated patients. This treatment delay-related increase in mortality was significantly higher as compared to the two groups of OHCA patients with shock (2.09) and without shock (1.34), as well as to haemodynamically stable patients (0.34, P < 0.0001). Conclusions: In patients with CS, the time elapsing from the first medical contact to primary PCI is a strong predictor of an adverse outcome. This patient group benefitted most from immediate PCI treatment, hence special efforts to shorten contact-to-balloon time should be applied in particular to these high-risk STEMI patients. Clinical Trial Registration: NCT00794001. PMID- 29452353 TI - A diagnostic germ cell score for immature testicular tissue at risk of germ cell loss. AB - STUDY QUESTION: Can a systematic scoring procedure provide crucial information on the status of highly heterogeneous immature human testicular tissues in the context of cryopreservation for fertility preservation? SUMMARY ANSWER: We developed a systematic histological score as a novel diagnostic tool which differentiates the patient cohort according to the status of germ cell differentiation and number of spermatogonia (normal, diminished and absent), and which could be relevant in the fertility clinic. WHAT IS KNOWN ALREADY: Cryopreservation of testicular tissue of immature boys is currently considered the option for future fertility restoration. However, experimental techniques for the derivation of sperm as well as valid diagnostic scoring of these immature testis tissues are not yet reported. STUDY DESIGN, SIZE, DURATION: Testicular tissues of 39 patients (aged 2-20 years) who attended our clinic for cryopreservation between 2010 and 2015 were analyzed to determine the variability of testicular tissue composition, germ cell numbers and differentiation status. PARTICIPANTS/MATERIALS, SETTING, METHODS: Human testicular tissue samples were divided into three groups. Group NT included patients suffering from diseases which do not directly affect the testes (n = 6; aged 6-14 years), group AT included patients suffering from diseases that directly affect the testes (n = 14; 2-17 years), and group KS (Klinefelter patients, n = 19; 12-20 years). Based on immunohistochemical stainings for MAGEA4, the differentiation status as well as the numbers of gonocytes, spermatogonia and spermatocytes were determined. MAIN RESULTS AND THE ROLE OF CHANCE: Testicular tissue samples from the NT group contained a mean of 100.3 spermatogonia/mm3 (*103). Highly heterogeneous and significantly lower mean numbers of spermatogonia were scored in testes from boys after cytotoxic exposures or with pre-existing disease (AT group: 35.7 spermatogonia/mm3 (*103); KS group: 1.8 spermatogonia/mm3 (*103)). In addition, the germ cell differentiation status was determined and revealed tissues with either spermatogonia and gonocytes, only spermatogonia, spermatogonia and spermatocytes, or all three germ cell types were present. Based on spermatogonial numbers and differentiation status, we developed a germ cell score which we applied to each individual patient sample. LIMITATIONS REASONS FOR CAUTION: Normal human testicular tissue samples are difficult to obtain for ethical reasons and the sample numbers were small. However, six such samples provide a valid baseline for the normal situation. WIDER IMPLICATIONS OF THE FINDINGS: Fertility preservation of immature male tissues is an emerging field and is currently offered in many specialized centers worldwide. Our diagnostic germ cell score delivers an easily applicable tool, facilitating patient counseling and thus ensuring comparability between the centers with regard to future studies.

PMID- 29452352 TI - Conditional ablation and conditional rescue models for Casq2 elucidate the role of development and of cell-type specific expression of Casq2 in the CPVT2 phenotype. AB - Cardiac calsequestrin (Casq2) associates with the ryanodine receptor 2 channel in the junctional sarcoplasmic reticulum to regulate Ca2+ release into the cytoplasm. Patients carrying mutations in CASQ2 display low resting heart rates under basal conditions and stress-induced polymorphic ventricular tachycardia (CPVT). In this study, we generate and characterize novel conditional deletion and conditional rescue mouse models to test the influence of developmental programs on the heart rate and CPVT phenotypes. We also compare the requirements for Casq2 function in the cardiac conduction system (CCS) and in working cardiomyocytes. Our study shows that the CPVT phenotype is dependent upon concurrent loss of Casq2 function in both the CCS and in working cardiomyocytes. Accordingly, restoration of Casq2 in only the CCS prevents CPVT. In addition, occurrence of CPVT is independent of the developmental history of Casq2 deficiency. In contrast, resting heart rate depends upon Casq2 gene activity only in the CCS and upon developmental history. Finally, our data support a model where low basal heart rate is a significant risk factor for CPVT. PMID- 29452354 TI - Alpha-synuclein inhibits Snx3-retromer-mediated retrograde recycling of iron transporters in S. cerevisiae and C. elegans models of Parkinson's disease. AB - We probed the role of alpha-synuclein (alpha-syn) in modulating sorting nexin 3 (Snx3)-retromer-mediated recycling of iron transporters in Saccharomyces cerevisiae and Caenorhabditis elegans. In yeast, the membrane-bound heterodimer Fet3/Ftr1 is the high affinity iron importer. Fet3 is a membrane-bound multicopper ferroxidase, whose ferroxidase domain is orthologous to human ceruloplasmin (Cp), that oxidizes external Fe+2 to Fe+3; the Fe+3 ions then channel through the Ftr1 permease into the cell. When the concentration of external iron is low (<1 uM), Fet3/Ftr1 is maintained on the plasma membrane by retrograde endocytic-recycling; whereas, when the concentration of external iron is high (>10 uM), Fet3/Ftr1 is endocytosed and shunted to the vacuole for degradation. We discovered that alpha-syn expression phenocopies the high iron condition: under the low iron condition (<1 uM), alpha-syn inhibits Snx3-retromer mediated recycling of Fet3/Ftr1 and instead shunts Fet3/Ftr1 into the multivesicular body pathway to the vacuole. alpha-Syn inhibits recycling by blocking the association of Snx3-mCherry molecules with endocytic vesicles, possibly by interfering with the binding of Snx3 to phosphatidylinositol-3 monophosphate. In C. elegans, transgenic worms expressing alpha-syn exhibit an age-dependent degeneration of dopaminergic neurons that is partially rescued by the iron chelator desferoxamine. This implies that alpha-syn-expressing dopaminergic neurons are susceptible to changes in iron neurotoxicity with age, whereby excess iron enhances alpha-syn-induced neurodegeneration. In vivo genetic analysis indicates that alpha-syn dysregulates iron homeostasis in worm dopaminergic neurons, possibly by inhibiting SNX-3-mediated recycling of a membrane-bound ortholog of Cp (F21D5.3), the iron exporter ferroportin (FPN1.1), or both. PMID- 29452356 TI - Baseline anticholinergic burden from medications predicts incident fatal and non fatal stroke in the EPIC-Norfolk general population. AB - Background: Stroke is primarily a disease of older age, with a substantial impact on global mortality and morbidity. Medications with anticholinergic effects are widely used, but no studies have been conducted to examine the relationship between anticholinergic burden (ACB) and stroke in a general population. Method: The sample was drawn from the EPIC-Norfolk cohort. Baseline assessments were carried out during 1993-97 and participants were followed up until March 2016. Participants were divided into four groups according to their total ACB score at baseline; these groups were those with a total ACB score of 0, 1, 2-3 and >3. After exclusion, Cox proportional hazards models were constructed to determine the associations between the ACB score groups and the risk of incident stroke and stroke mortality. Sensitivity analysis and propensity score matched analyses were performed. Results: In total 25 639 participants attended the first health check; 3917 participants were excluded, leaving 21 722 participants to be included. Participants had a mean age [standard deviation (SD)] of 58.9 (9.2) years (54.4% women). Of these, 2131 suffered incident stroke and 562 died from stroke. Mean follow-up was approximately 18 years for both outcomes. In the fully adjusted model, those with an ACB of >3 had 59% relative risk of incident stroke {hazard ratio [HR] [95% confidence interval (CI) 1.59 [1.34-1.89]} and 86% relative risk of stroke mortality [1.86 (1.37-2.53)] compared with those in ACB 0 category. Sensitivity analyses and propensity score matched analyses showed similar results. Conclusions: Our results provide an incentive for the cautious use of medications with anticholinergic properties, to help reduce the global burden of stroke. PMID- 29452357 TI - del Nido cardioplegia in adult cardiac surgery: beyond single-valve surgery. AB - OBJECTIVES: In recent years, the use of del Nido (DN) cardioplegia has been reported in single-valve surgery or isolated coronary artery bypass surgery with acceptable outcomes. The reports of its use in more complex adult cardiac procedures, however, have been scarce. METHODS: We enrolled a total of 149 adult patients who underwent heart valve surgery with the use of DN cardioplegia between May 2014 and December 2016. For a benchmark comparison, 892 patients who underwent cardiac valve surgery with blood cardioplegia during the same period served as controls. To reduce selection bias, propensity score matching was used; the inverse probability of treatment weighting method was performed for further validations. RESULTS: Overall, 57.7% of patients in the DN group underwent multiple or complex cardiac procedures. Early mortality rates were 0.7% and 2.4% in the DN and blood groups, respectively (P = 0.31). Propensity score matching yielded 111 pairs of patients who were well balanced for all 23 measured baseline covariates. In the matched cohort, the postoperative peak troponin I levels (P = 0.004) and the aortic clamping times (P < 0.001) were significantly lower and shorter compared with those in the blood group. There were no significant differences in early mortality rates (1.9% vs 0%, P > 0.99), low cardiac output (P = 0.57) and neurological events (P = 0.21). The quantities of postoperative transfusions (P = 0.008) and fluid supplements (P < 0.001) were significantly lower in the matched DN group compared with the blood group. CONCLUSIONS: The use of DN in adult valve surgery including complex procedures may confer acceptable outcomes comparable to or even superior to those obtained with the use of blood cardioplegia.

PMID- 29452355 TI - Culture-Facilitated Comparative Genomics of the Facultative Symbiont Hamiltonella defensa. AB - Many insects host facultative, bacterial symbionts that confer conditional fitness benefits to their hosts. Hamiltonella defensa is a common facultative symbiont of aphids that provides protection against parasitoid wasps. Protection levels vary among strains of H. defensa that are also differentially infected by bacteriophages named APSEs. However, little is known about trait variation among strains because only one isolate has been fully sequenced. Generating complete genomes for facultative symbionts is hindered by relatively large genome sizes but low abundances in hosts like aphids that are very small. Here, we took advantage of methods for culturing H. defensa outside of aphids to generate complete genomes and transcriptome data for four strains of H. defensa from the pea aphid Acyrthosiphon pisum. Chosen strains also spanned the breadth of the H. defensa phylogeny and differed in strength of protection conferred against parasitoids. Results indicated that strains shared most genes with roles in nutrient acquisition, metabolism, and essential housekeeping functions. In contrast, the inventory of mobile genetic elements varied substantially, which generated strain specific differences in gene content and genome architecture. In some cases, specific traits correlated with differences in protection against parasitoids, but in others high variation between strains obscured identification of traits with likely roles in defense. Transcriptome data generated continuous distributions to genome assemblies with some genes that were highly expressed and others that were not. Single molecule real-time sequencing further identified differences in DNA methylation patterns and restriction modification systems that provide defense against phage infection. PMID- 29452360 TI - The role of transvenous lead extraction in the management of redundant or malfunctioning pacemaker and defibrillator leads post ELECTRa. AB - Cardiac implantable electronic devices implantation rates have increased over the past decade due to broader indications and an ageing population. Similarly, device and lead complications have also risen. The management of pacemaker/defibrillator leads that are no longer required (redundant) or malfunctioning, can be contentious. There is a need to balance the risk of transvenous lead extraction (TLE) against those of lead abandonment. The recently published European Lead Extraction ConTRolled Registry (ELECTRa) study provides contemporary outcomes for TLE across Europe with important implications for the management of redundant and/or malfunctioning leads. This review article discusses the potential complications for each interventional approach when managing redundant or malfunctioning pacemaker leads. PMID- 29452359 TI - Convergent Amino Acid Signatures in Polyphyletic Campylobacter jejuni Subpopulations Suggest Human Niche Tropism. AB - Human infection with the gastrointestinal pathogen Campylobacter jejuni is dependent upon the opportunity for zoonotic transmission and the ability of strains to colonize the human host. Certain lineages of this diverse organism are more common in human infection but the factors underlying this overrepresentation are not fully understood. We analyzed 601 isolate genomes from agricultural animals and human clinical cases, including isolates from the multihost (ecological generalist) ST-21 and ST-45 clonal complexes (CCs). Combined nucleotide and amino acid sequence analysis identified 12 human-only amino acid KPAX clusters among polyphyletic lineages within the common disease causing CC21 group isolates, with no such clusters among CC45 isolates. Isolate sequence types within human-only CC21 group KPAX clusters have been sampled from other hosts, including poultry, so rather than representing unsampled reservoir hosts, the increase in relative frequency in human infection potentially reflects a genetic bottleneck at the point of human infection. Consistent with this, sequence enrichment analysis identified nucleotide variation in genes with putative functions related to human colonization and pathogenesis, in human-only clusters. Furthermore, the tight clustering and polyphyly of human-only lineage clusters within a single CC suggest the repeated evolution of human association through acquisition of genetic elements within this complex. Taken together, combined nucleotide and amino acid analysis of large isolate collections may provide clues about human niche tropism and the nature of the forces that promote the emergence of clinically important C. jejuni lineages. PMID- 29452361 TI - IUI: review and systematic assessment of the evidence that supports global recommendations. AB - BACKGROUND: IUI with or without ovarian stimulation (OS) has become a first-line treatment option for many infertile couples, worldwide. The appropriate treatment modality for couples and their clinical management through IUI or IUI/OS cycles must consider maternal and perinatal outcomes, most notably the clinical complication of higher-order multiple pregnancies associated with IUI-OS. With a current global emphasis to continue to decrease maternal and perinatal mortality and morbidity, the World Health Organization (WHO) had established a multi-year project to review the evidence for the establishment of normative guidance for the implementation of IUI as a treatment to address fertility problems, and to consider its cost-effectiveness for lower resource settings. OBJECTIVE AND RATIONALE: The objective of this review is to provide a review of the evidence of 13 prioritized questions that cover IUI with and without OS. We provide summary recommendations for the development of global, evidence-based guidelines based upon methodology established by the WHO. SEARCH METHODS: We performed a comprehensive search using question-specific relevant search terms in May 2015. For each PICO (Population, Intervention, Comparison and Outcomes) drafted by WHO, specific search terms were used to find the available evidence in MEDLINE (1950 to May 2015) and The Cochrane Library (until May 2015). After presentation to an expert panel, a further hand search of references in relevant reviews was performed up to January 2017. Articles that were found to be relevant were read and analysed by two investigators and critically appraised using the Cochrane Collaboration's tool for assessing risk of bias, and AMSTAR in case of systematic reviews. The quality of the evidence was assessed using the GRADE system. An independent expert review process of our analysis was conducted in November 2016. OUTCOMES: This review provides an assessment and synthesis of the evidence that covers 13 clinical questions including the indications for the use of IUI versus expectant management, the sperm parameters required, the best and optimal method of timing and number of inseminations per cycle, prevention strategies to decrease multiple gestational pregnancies, and the cost-effectiveness of IUI versus IVF. We provide an evidence-based formulation of 20 recommendations, as well as two best practice points that address the integration of methods for the prevention of infection in the IUI laboratory. The quality of the evidence ranges from very low to high, with evidence that may be decades old but of high quality, however, we further discuss where critical research gaps in the evidence remain. WIDER IMPLICATIONS: This review presents an evidence synthesis assessment and includes recommendations that will assist health care providers worldwide with their decision-making when considering IUI treatments, with or without OS, for their patients presenting with fertility problems.

AB - There is mixed evidence with some suggesting walking can be increased up to the recommended level through interventions based on behaviour change models and others showing partial or no effects [Arbour and Ginis (A randomised controlled trial of the effects of implementation intentions on women's walking behaviour. Psychol Health, 2009;24:49-65); Merom et al. (Can a motivational intervention overcome an unsupportive environment for walking-findings from the Step-by-Step Study. Ann Behav Med 2009;38:137-46); Ornes and Ransdell (A pilot study examining exercise self-efficacy as a mediator for walking behavior in college-age women. Perceptual Motor Skills, 2010;1101098-104)]. Taken together, prior studies suggest that ongoing research attention is warranted. Walking behaviour change intervention studies were searched using key search words 'walking promotion' and 'pedometer' in the PubMed database. Initially, 87 articles were found and 25 walking behaviour change interventions were reviewed to focus attention on reported theory use. Results of the review suggest that interventions that are theoretically underpinned may be no more effective than their counterparts. The Transtheoretical Model (TTM) and Social Cognitive Models were most frequently reported with positive effects noted for TTM use. The review also indicates that using single theory may be better than using multiple theories in a single intervention.

AB - Motivation: StructureMapper is a high-throughput algorithm for automated mapping of protein primary amino sequence locations to existing three-dimensional protein structures. The algorithm is intended for facilitating easy and efficient utilization of structural information in protein characterization and proteomics. StructureMapper provides an analysis of the identified structural locations that includes surface accessibility, flexibility, protein-protein interfacing, intrinsic disorder prediction, secondary structure assignment, biological assembly information and sequence identity percentages, among other metrics. Results: We have showcased the use of the algorithm by estimating the coverage of structural information of the human proteome, identifying critical interface residues in DNA polymerase gamma, profiling structurally protease cleavage sites and post-translational modification sites, and by identifying putative, novel phosphoswitches. Availability and implementation: The StructureMapper algorithm is available as an online service and standalone implementation at http://structuremapper.uta.fi. Supplementary information: Supplementary data are available at Bioinformatics online.

AB - Accumulation of unfolded secretory proteins in the endoplasmic reticulum (ER), namely ER stress, is hazardous to eukaryotic cells and promotes the unfolded protein response (UPR). Ire1 is an ER-located transmembrane protein that senses ER stress and triggers the UPR. According to previous in vitro experiments, 4 phenylbutyrate (4-PBA) works as a chemical molecular chaperone. Since 4-PBA attenuates the UPR in mammalian tissue cultures, this chemical may have clinical potential for restoring ER-stressing conditions. In this study, we investigated 4 PBA's mode of action using the yeast Saccharomyces cerevisiae as a model organism. Although 4-PBA blocked a dithiothreitol (DTT)-induced UPR, it did not appear to restore impairment of ER protein folding that was caused by DTT. Moreover, even under non-stress conditions, 4-PBA attenuated UPR that was induced by an Ire1 mutant that exhibits a substantial activity without sensing ER accumulation of unfolded proteins. We also found that 4-PBA drastically promotes the degradation of Ire1. These observations indicate that at least in the case of yeast cells, 4-PBA suppresses the UPR not through restoration of the ER function to correctly fold proteins. Instead, the accelerated degradation of Ire1 possibly explains the reason why the UPR is attenuated by 4-PBA. PMID- 29452365 TI - Indigenous medicine and biomedical health care in fragile settings: insights from Burundi. AB - This study contributes to the health policy debate on medical systems integration by describing and analysing the interactions between health-care users, indigenous healers, and the biomedical public health system, in the so far rarely documented case of post-conflict Burundi. We adopt a mixed-methods approach combining (1) data from an existing survey on access to health-care, with 6,690 individuals, and (2) original interviews and focus groups conducted in 2014 with 121 respondents, including indigenous healers, biomedical staff, and health-care users. The findings reveal pluralistic patterns of health-care seeking behaviour, which are not primarily based on economic convenience or level of education. Indigenous healers' diagnosis is shown to revolve around the concept of 'enemy' and the need for protection against it. We suggest ways in which this category may intersect with the widespread experience of trauma following the civil conflict. Finally, we find that, while biomedical staff displays ambivalent attitudes towards healers, cross-referrals occasionally take place between healers and health centres. These findings are interpreted in light of the debate on health systems integration in Sub-Saharan Africa. In particular, we discuss policy options regarding healers' accreditation, technical training, management of cross-referrals as well as of herb-drug interactions; and we emphasise healers' psychological support role in helping communities deal with trauma. In this respect, we argue that the experience of conflict, and the experiences and conceptualizations of mental and physical illness, need to be taken into account when devising appropriate public or international health policy responses. PMID- 29452366 TI - Prevalence and Incidence of Anal and Cervical High-Risk Human Papillomavirus (HPV) Types Covered by Current HPV Vaccines Among HIV-Infected Women in the SUN Study. AB - Background: Nonavalent (9v) human papilloma virus vaccine targets high-risk human papillomavirus (HR-HPV) types 16, 18, 31, 33, 45, 52, 58, and low-risk 6, 11. We examined prevalence, incidence, and clearance of anal and cervical HR-HPV in HIV infected women. Methods: The SUN Study enrolled 167 US women in 2004-2006. Anal and cervical specimens were collected annually for cytology and identification of 37 HPV types: 14 HR included: 9v 16, 18, 31, 33, 45, 52, 58; non-9v 35, 39, 51, 56, 59, 66, 68. Results: Baseline characteristics of 126 women included: median age 38 years; 57% non-Hispanic black; 67% HIV RNA < 400 copies/mL; 90% CD4 counts >=200 cells/mm3. HPV prevalence at anus and cervix was 90% and 83%; for 9v HR-HPV types, 67% and 51%; non-9v HR-HPV, 54% and 29%, respectively. The 9v and non-9v HR-HPV incidence rates/100 person-years were similar (10.4 vs 9.5; 8.5 vs 8.3, respectively); 9v clearance rates were 42% and 61%; non-9v 46% and 59%, in anus and cervix, respectively. Conclusions: Anal HR-HPV prevalence was higher than cervical, with lower clearance; incidence was similar. Although prevalence of non 9v HR-HPV was substantial, 9v HR-HPV types were generally more prevalent. These findings support use of nonavalent vaccine in HIV-infected women. PMID- 29452367 TI - Variant in human POFUT1 reduces enzymatic activity and likely causes a recessive microcephaly, global developmental delay with cardiac and vascular features. AB - Protein O-fucosyltransferase-1 (POFUT1) adds O-fucose monosaccharides to epidermal growth factor-like (EGF) repeats found on approximately 100 mammalian proteins, including Notch receptors. Haploinsufficiency of POFUT1 has been linked to adult-onset Dowling Degos Disease (DDD) with hyperpigmentation defects. Homozygous deletion of mouse Pofut1 results in embryonic lethality with severe Notch-like phenotypes including defects in somitogenesis, cardiogenesis, vasculogenesis and neurogenesis, but the extent to which POFUT1 is required for normal human development is not yet understood. Here we report a patient with a congenital syndrome consisting of severe global developmental delay, microcephaly, heart defects, failure to thrive and liver disease with a previously unreported homozygous NM_015352.1: c.485C>T variant (p.Ser162Leu) in POFUT1 detected by exome sequencing. Both parents are heterozygotes and neither manifests any signs of DDD. No other detected variant explained the phenotype. This variant eliminated a conserved N-glycosylation sequon at Asn160 in POFUT1 and profoundly decreased POFUT1 activity in patient fibroblasts compared to control fibroblasts. Purified p.Ser162Leu mutant protein also showed much lower POFUT1 activity with a lower affinity for EGF acceptor substrate than wild type POFUT1. Eliminating the N-glycan sequon by replacing Asn160 with Gln had little effect on POFUT1 activity, suggesting that loss of the glycan is not responsible for the defect. Furthermore, the p.Ser162Leu mutant showed weaker ability to rescue Notch activity in cell-based assays. These results suggest that this N glycan of POFUT1 is not required for its proper enzymatic function, and that the p.Ser162Leu mutation of POFUT1 likely causes global developmental delay, microcephaly with vascular and cardiac defects. PMID- 29452368 TI - Validity of the Swedish Cardiac Surgery Registry. AB - OBJECTIVES: Our goal was to validate the Swedish Cardiac Surgery Registry by reviewing the reported cardiac operations to assess the completeness and quality of the registered data and the EuroSCORE II variables. METHODS: A total of 5837 cardiac operations were reported to the Swedish Cardiac Surgery Registry in Sweden during 2015. A randomly selected sample of 753 patient records (13%) was scrutinized by 3 surgeons at all 8 units in Sweden performing open cardiac surgery in adults. RESULTS: Coverage was excellent with 99% [95% confidence interval (CI) 98-99%] of the performed procedures found in the registry. Reported waiting times for surgery were correct in 78% (95% CI 76-79%) of the cases. The main procedural code was correctly reported in 96% (95% CI 95-97%) of the cases. The correlation between reported and monitored logistic EuroSCORE II had a coefficient of 0.79 (95% CI 0.76-0.82), and the median difference in EuroSCORE II was 0% (interquartile range -0.4% to 0.4%). The majority of EuroSCORE II variables had good agreement and coherence; however, New York Heart Association functional class, preoperative renal dysfunction, left ventricular ejection fraction, Canadian Cardiovascular Society Class IV angina and poor mobility were less robust. Postoperative complications were rare and in general had a high degree of completeness and agreement. CONCLUSIONS: The reliability of the variables in the national Swedish Cardiac Surgery Registry was excellent. Thus, the registry is a valuable source of data for quality studies and research. Some EuroSCORE II variables require improved and stricter definitions to obtain uniform reporting and high validity. PMID- 29452369 TI - In search of the best xenogeneic material for a paediatric conduit: an analysis of clinical data. AB - OBJECTIVES: In this study, we aimed to determine the incidence of reintervention and calcification of xenografts in paediatric patients who underwent placement of the right ventricle-to-pulmonary artery valved conduits. METHODS: We retrospectively analysed clinical data of paediatric patients (1 day-18 years) who underwent right ventricular outflow tract reconstruction using xenograft from 2000 to 2016 at a single centre. RESULTS: A total of 301 patients underwent the placement of 337 xenografts, including glutaraldehyde-treated bovine jugular vein (n = 171, 50.7%), glutaraldehyde-treated bovine pericardial valved conduit (n = 75, 22.3%), diepoxy-treated porcine aortic conduit (n = 58, 17.2%) and diepoxy treated bovine pericardial valved conduit (DE-PVC) (n = 33, 9.8%). There were 284 (84.3%) primary implantations and 53 (15.7%) reimplantations. The median follow up was 4.2 years (range 1.5 months-14.5 years). The multivariate regression analysis did not reveal statistically significant associations of the first reintervention with the type of xenograft (P = 0.78). At reintervention, calcification of the wall and/or cusps was the main cause of conduit dysfunction in 66.4% of cases. On the basis of the multivariate Cox regression analysis, xenograft types were significant predictors of reintervention caused by conduit calcification (P = 0.012). The diepoxy-treated porcine aortic conduit group had the risk of calcification 3 times higher than the glutaraldehyde-treated bovine jugular vein group (P < 0.001).The glutaraldehyde-treated bovine pericardial valved conduit and diepoxy-treated bovine pericardial valved conduit groups had the risk of calcification comparable with the glutaraldehyde-treated bovine jugular vein group in multivariate proportional hazards model (P = 0.36 and P = 0.59, respectively). CONCLUSIONS: We have not revealed significant difference in the freedom from first reintervention among types of conduit. Calcification leading to the conduit dysfunction was present in all groups; however, diepoxy treated porcine aortic conduits demonstrated suboptimal results in terms of calcification at follow-up. PMID- 29452370 TI - Blood cardioplegia for cardiac surgery in acute myocardial infarction: rat experiments with two widely used solutions. AB - OBJECTIVES: Blood cardioplegia (BCP) can be used in different ways to protect the heart from ischaemia-reperfusion injury during cardiac surgery. Because there could be differences between warm and cold intermittent cardioplegia with or without warm reperfusion, we investigated the influence of 2 blood cardioplegia solutions on cardiac function, metabolism and infarct size in stable and infarcted rat hearts. METHODS: The hearts of 32 male Wistar rats were excised and inserted into a blood-perfused isolated heart apparatus. In 16 hearts, an acute myocardial infarction was induced by ligation of the left anterior descending coronary artery at least 30 min before aortic clamping. After aortic clamping, either Calafiore or Buckberg BCP was administered. During reperfusion, coronary blood flow, left ventricular developed pressure and dp/dt max were recorded, and oxygen consumption and lactate production were determined. The infarct size after 90 min of reperfusion was measured by triphenyl tetrazolium chloride staining. The hearts of rats without infarction were investigated using transmission electron microscopy. RESULTS: In hearts without infarction, haemodynamic recovery was similar for Calafiore and Buckberg solutions: left ventricular developed pressure [Cala 62% of baseline (BL), Buck 58% BL] and dp/dt max (Cala 83% BL, Buck 89% BL). Coronary flow, which was slightly less in infarcted hearts, also recovered similarly after the administration of the 2 BCP solutions (Cala 65% BL, Buck 68% BL). During reperfusion, lactate production was similar (Cala 0.85 ml/min, Buck 1.0 ml/min), and the cellular oedema index and mitochondrial swelling were comparable between the 2 groups. In hearts with infarction, left ventricular developed pressure (Cala 58% BL, Buck 56% BL) and dp/dt max (Cala 79% BL, Buck 72% BL) showed similar recovery for reperfusion with Calafiore or Buckberg BCP. In addition, coronary flow recovered similarly (Cala 54% BL, Buck 57% BL). During reperfusion, myocardial oxygen consumption was lower in the Cala (67% BL) than in the Buck (82% BL) group, but lactate production was similar between the Cala (1.1 ml/min) and the Buck (1.1 ml/min) groups. Myocardial infarct size was also similar in the Cala group (24%) and in the Buck group (26%). CONCLUSIONS: In stable perfused rat hearts and in an in vitro model of acute myocardial infarction, the 2 BCP solutions offer equally good myocardial protection. PMID- 29452371 TI - A bidirectional association between cognitive ability in young adulthood and epilepsy: a population-based cohort study. AB - Aim: To investigate the bidirectional association between cognitive ability in young adulthood and epilepsy. Methods: This cohort study included 1 159 076 men enrolled in the mandatory conscription board examination from the Danish Conscription Database (DCD; 658 465 men examined 1957-84), the Danish Defence Personnel Organization Database (DPOD; 216 509 men examined 1987-2005) and the Danish Conscription Registry (DCR; 284 102 men examined 2006-15). A supplementary analysis included 14 814 female volunteers. Cognitive ability was measured at conscription, and epilepsy was ascertained by physician diagnoses in the Danish National Patient Registries 1977-2016 [using International Classification of Diseases (ICD) codes: ICD-8-345; ICD-10-G40-G41]. Differences in cognitive ability in relation to epilepsy status at the time of conscription (age 19) were calculated using linear regression. The risk of epilepsy associated with cognitive ability was estimated using Cox regression models, split at age at follow-up (40 and 60 years) and adjusted for year of birth, cerebrovascular disease, traumatic brain injury and education. Results: In all, 5097 (1.0%) men from the DPOD and DCR were diagnosed with epilepsy before conscription, and they had about 0.25 standard deviation (SD) lower cognitive scores than men without epilepsy. The largest difference in cognition was seen for those with the largest number of hospital contacts. A total of 22 364 (1.9%) men developed epilepsy, and cognitive ability was inversely associated with the risk of epilepsy. With the end of follow-up at age 40 years, the adjusted hazard ratio (HR)per SD increase was 0.75 (95% confidence interval = 0.73-0.77). The association attenuated with increasing age at diagnosis. The findings were replicated in female conscripts. Conclusions: The cognitive impairment seen in adults with epilepsy seems to reflect combined effects of epileptic processes and lower premorbid cognitive ability. PMID- 29452372 TI - Impact of Timing of Influenza Vaccination in Pregnancy on Transplacental Antibody Transfer, Influenza Incidence, and Birth Outcomes: A Randomized Trial in Rural Nepal. AB - Background: Maternal influenza vaccination protects mothers and their infants in low resource settings, but little is known about whether the protection varies by gestational age at vaccination. Methods: Women of childbearing age in rural southern Nepal were surveilled for pregnancy, consented and randomized to receive maternal influenza vaccination or placebo, with randomization stratified on gestational age (17-25 or 26-34 weeks). Enrollment occurred in 2 annual cohorts, and vaccinations occurred from April 2011 through September 2013. Results: In sum, 3693 women consented and enrolled, resulting in 3646 live births. Although cord blood antibody titers and the rise in maternal titers were generally greater when women were vaccinated later in pregnancy, this was not statistically significant. The incidence risk ratio (IRR) for maternal influenza in pregnancy through 6 months postpartum was 0.62 (95% confidence interval [CI]: 0.35, 1.10) for those vaccinated 17-25 weeks gestation and 0.89 (95% CI: 0.39, 2.00) for those 26-34 weeks. Infant influenza IRRs were 0.73 (95% CI: 0.51, 1.05) for those whose mothers were vaccinated earlier in gestation, and 0.63 (95% CI: 0.37, 1.08) for those later. Relative risks (RR) for low birthweight were 0.83 (95% CI: 0.71, 0.98) and 0.90 (95% CI: 0.72, 1.12) for 17-25 and 26-34 weeks gestation at vaccination, respectively. IRRs did not differ for small-for-gestational age or preterm. No RRs were statistically different by timing of vaccine receipt. Conclusions: Vaccine efficacy did not vary by gestational age at vaccination, making maternal influenza immunization programs easier to implement where women present for care late in pregnancy.

PMID- 29452375 TI - 1alpha-Hydroxycholecalciferol improves the growth performance and up-regulates the mRNA expression of vitamin D receptor in the small intestine and kidney of broiler chickens. AB - 1alpha-Hydroxycholecalciferol (1alpha-OH-D3) is a vitamin D derivative. The objective of this study was to evaluate the effects of 1alpha-OH-D3 on the growth and the mRNA expression of vitamin D receptor (VDR) in the small intestine and kidney of chickens. A total of 240 males of one-day-old Ross 308 broilers was randomly assigned to 4 treatments with 5 replicates of 12 birds per replicate. Three levels of 1alpha-OH-D3 (1.25, 2.5, and 5 MUg/kg) were added to a basal diet containing 0.50% calcium (Ca), 0.25% non-phytate phosphorus (NPP), and without supplemental cholecalciferol (vitamin D3). The control diet contained 1.00% Ca, 0.45% NPP, and 25 MUg/kg cholecalciferol. Dietary 1alpha-OH-D3 levels linearly improved the average daily feed intake (ADFI), average daily gain (ADG), femur and tibia mineralization, and plasma Ca concentration, and retained Ca and total phosphorus (tP) amounts in broilers from 1 to 21 d of age (P < 0.05). In addition, 1alpha-OH-D3 also linearly up-regulated the mRNA expression levels of VDR in the duodenum as well as those of VDR and sodium-phosphate cotransporter NaPi-IIa and NaPi-IIc in the kidney of broilers (P < 0.05). However, 1alpha-OH-D3 did not affect the mRNA levels of 25-hydroxylase in the liver or NaPi-IIb in the duodenum (P > 0.05). No differences were observed in the ADFI, ADG, bone length, plasma mineral concentration, retained tP amount, or the mRNA levels of the above genes (except for VDR in the kidney) between the birds fed the diet with 5 MUg/kg 1alpha-OH-D3 and the birds fed the control diet (P > 0.05). By contrast, the weight, ash weight, ash percentage, and Ca percentage of the bone, retained Ca amount, and the mRNA level of VDR in the kidney were lower in the birds fed the diet with 5 MUg/kg 1alpha-OH-D3 than in the birds fed the control diet (P < 0.05). These data indicate that 1alpha-OH-D3 up-regulates the gene expression of VDR in the small intestine and kidney at the transcriptional level, thereby improving the growth performance and bone mineralization of broiler chickens from 1 to 21 d of age. PMID- 29452376 TI - The Vacuolar Transportome of Plant Specialized Metabolites. AB - The plant vacuole is a cellular compartment that is essential to plant development and growth. Often plant vacuoles accumulate specialized metabolites, also called secondary metabolites, which constitute functionally and chemically diverse compounds that exert in planta many essential functions and improve the plant's fitness. These metabolites provide, for example, chemical defense against herbivorous and pathogens or chemical attractants (color and fragrance) to attract pollinators. The chemical composition of the vacuole is dynamic, and is altered during development and as a response to environmental changes. To some extent these alterations rely on vacuolar transporters, which import and export compounds into and out of the vacuole, respectively. During the past decade, significant progress was made in the identification and functional characterization of the transporters implicated in many aspects of plant specialized metabolism. Still, deciphering the molecular players underlying such processes remains a challenge for the future. In this review, we present a comprehensive summary of the most recent achievements in this field.

PMID- 29452377 TI - Discordance in the Dependence on Kisspeptin Signaling in Mini Puberty vs Adolescent Puberty: Human Genetic Evidence. AB - Context: Hypothalamic kisspeptin signaling plays a critical role in the initiation and maintenance of reproductive function. Biallelic mutations in the coding sequence of KISS1R (GPR54) have been identified in patients with idiopathic hypogonadotropic hypogonadism, but it is unknown whether biallelic variants can also be associated with related reproductive disorders. Case Description: A missense homozygous variant (c.890G>T p.R297L) in KISS1R was identified in a child who presented with microphallus and bilateral cryptorchidism. This variant has been reported to reduce, but not abolish, postreceptor signaling in vitro. Biochemical evaluation during the neonatal period revealed low testosterone levels. By 11 years and 8 months, the boy began demonstrating increases in testicular volume. By 17 years and 3 months, his testicular volume was 20 mL; his penile length was 7.3 cm; and he had adult levels of circulating gonadotropins and testosterone. Conclusion: This case report associates biallelic loss-of-function mutations in KISS1R with normal timing of adolescent puberty. Because these coding sequence variants occurred in a patient with microphallus and cryptorchidism, they demonstrate different levels of dependence of the hypothalamic-pituitary-gonadal cascade on kisspeptin signaling at distinct times in the reproductive life span. The suppression of the hypothalamic-pituitary-gonadal cascade during early life but not adolescence suggests that the mini puberty of infancy depends more on kisspeptin-induced, gonadotropin-releasing hormone-induced luteinizing hormone secretion than does adolescent puberty.

AB - Background: We examined whether a high-dose inactivated influenza vaccine was more efficacious in preventing hospitalizations than a standard-dose vaccine in the Veterans Health Administration (VHA) senior population. Methods: This study estimated the relative vaccine effectiveness (rVE) of high dose versus standard dose using a retrospective cohort of VHA patients 65 years of age or older in the 2015-2016 influenza season. To adjust for measured confounders, we matched each high-dose recipient with up to 4 standard-dose recipients vaccinated at the same location within a 2-week period and having 2 or more pre-existing medical comorbidities. We used the previous event rate ratio method (PERR), a type of difference-in-differences analysis, to adjust for unmeasured confounders. Results: We evaluated 104965 standard-dose and 125776 high-dose recipients; matching decreased the population to 49091 standard-dose and 24682 high-dose recipients. The matched, PERR-adjusted rVE was 25% (95% confidence interval [CI], 2%-43%) against influenza- or pneumonia-associated hospitalization, 7% (95% CI, 2% to 14%) against all-cause hospitalization, 14% (95% CI, -8% to 32%) against influenza- or pneumonia-associated outpatient visit, 5% (95% CI, 2%-8%) against all-cause outpatient visit, and 38% (95% CI, -5% to 65%) against laboratory confirmed influenza. Conclusions: In protecting senior VHA patients against influenza- or pneumonia-associated hospitalization, a high-dose influenza vaccine is more effective than a standard-dose vaccine. PMID- 29452382 TI - Simulated ablation for detection of cells impacting paracrine signalling in histology analysis. AB - Intra-tumour phenotypic heterogeneity limits accuracy of clinical diagnostics and hampers the efficiency of anti-cancer therapies. Dealing with this cellular heterogeneity requires adequate understanding of its sources, which is extremely difficult, as phenotypes of tumour cells integrate hardwired (epi)mutational differences with the dynamic responses to microenvironmental cues. The later comes in form of both direct physical interactions, as well as inputs from gradients of secreted signalling molecules. Furthermore, tumour cells can not only receive microenvironmental cues, but also produce them. Despite high biological and clinical importance of understanding spatial aspects of paracrine signaling, adequate research tools are largely lacking. Here, a partial differential equation (PDE)-based mathematical model is developed that mimics the process of cell ablation. This model suggests how each cell might contribute to the microenvironment by either absorbing or secreting diffusible factors, and quantifies the extent to which observed intensities can be explained via diffusion-mediated signalling. The model allows for the separation of phenotypic responses to signalling gradients within tumour microenvironments from the combined influence of responses mediated by direct physical contact and hardwired (epi)genetic differences. The method is applied to a multi-channel immunofluorescence in situ hybridisation (iFISH)-stained breast cancer histological specimen, and correlations are investigated between: HER2 gene amplification, HER2 protein expression and cell interaction with the diffusible microenvironment. This approach allows partial deconvolution of the complex inputs that shape phenotypic heterogeneity of tumour cells and identifies cells that significantly impact gradients of signalling molecules. PMID- 29452383 TI - The Effectiveness of Asian Bush Mosquito (Aedes japonicus japonicus) Control Actions in Colonised Peri-urban Areas in the Netherlands. AB - The Asian bush mosquito (Aedes japonicus japonicus (Theobald)) is an invasive mosquito species in Europe. In 2012, it was for the first time detected in the Netherlands, in the municipality of Lelystad. After further research, thousands of specimens were found in the surrounding peri-urban areas of the city. A targeted mosquito control campaign began in 2015 with the objective of reducing populations in locations with the highest concentrations of Ae. japonicus breeding sites: allotment garden complexes. Mosquito control consisted of source reduction combined with application of the larvicide Vectomax in breeding sites. At eight complexes, mosquito control effectiveness has been systematically measured by sampling larvae from breeding sites. Six measurements were performed between 2015 and 2016. Results show that the effectiveness of mosquito control actions was similar in all treated allotment gardens and resulted in a significant reduction in Ae. japonicus larval abundance. Rain barrels at the allotments represent the most frequent breeding site in Lelystad, but every water filled artificial container is a potential breeding site for the species. Ae. japonicus was not found in the samples taken in other allotment gardens in the province of Flevoland; however, the collection methodology used proven to be effective in detecting this species when it has newly colonized surrounding areas. Targeted mosquito control actions at the breeding sites are crucial for successful reduction of populations of an invasive mosquito species, and systematic measurements of the effectiveness, is in this case, the base to understand the dynamics of Ae. japonicus populations after mosquito control.

AB - Introduction: Among youth, the frequency and prevalence of using more than one tobacco (small cigar, cigarette, and hookah) or nicotine-containing product (e cigarettes-ENDS) are changing. These shifts pose challenges for regulation, intervention, and prevention campaigns because of scant longitudinal data on the stability of use patterns in this changing product landscape. Methods: A nationally representative longitudinal survey of 15- to 21-year olds (n = 15,275) was used to describe transitions between never use, noncurrent use, and past 30 day use of combustible tobacco, e-cigarettes (ENDS), and dual use of both kinds of products. A multistate model was fit to observations collected every 6 months across 2.5 years to estimate the probability of transitions between states (TPs), the average time in state (sojourn time), and the effect of age on transitions. Results: Current state strongly predicted future state over time intervals of 1 year or less, but only weakly predicted future state at longer intervals: TP to noncurrent use was higher for ENDS-only than combustible-only users over a 6 month interval but was similar for both groups over a 2-year interval. Sojourn time was significantly longer for combustible-only (0.52 years) and dual use (0.55 years) than ENDS-only use (0.27 years); older youth were more likely than younger youth to stay combustible tobacco users or noncurrent users. Conclusions: The dynamics of transitions between combustible tobacco products and ENDS in a population of youth and young adults suggest that policy and prevention efforts must consider the frequent changes and instability over a 1-year or less time period in use patterns among young people. Implications: The study addresses an urgent need in public health for timely information on how youth and young adults use tobacco and nicotine products. We found that youth, particularly adolescents, moved frequently between using ENDS and combustible tobacco products either alone or together. Importantly, the utility of current-use states for predicting future use states declined for time horizons longer than 1 year. Our results demonstrate a need for caution in interpreting product transitions. Longitudinal data with frequent observations and coverage of a wide range of possible product types is required to fully characterize usage patterns in youth.

AB - Work was undertaken to investigate the potential use of housefly (Musca domestica) larvae reared on broiler manure as a source of nutrition for poultry production in the United Kingdom. Nutritional analysis showed that larvae have a high (>45% dry wt.) protein content and a favorable amino acid profile that is rich in key amino acids, such as lysine and methionine. A broiler digestibility trial was carried out to determine the apparent ileal digestibility coefficients (AIDC) and true ileal digestibility coefficients (TIDC) of amino acids (AA) from insect larval meal (ILM) from M. domestica and fishmeal (FM) in broiler chickens. This was calculated using multiple linear regression technique based upon 3 inclusions of each protein source in a semisynthetic diet. One-hundred-forty-four day-old male (Ross 308) broilers were fed from hatch on a commercial starter diet for 20 days. Experimental diets were fed from d 21 to 28, and feed intakes were measured daily. On d 28, the trial was terminated, ileal digesta were collected for the determination of AIDC and TIDC of AA, and inflammatory responses (gizzard erosion and eye discharge) were measured. No significant differences were observed in digestibilities between protein sources for any AA. Furthermore, ILM feeding did not induce gizzard erosion or eye discharge at any inclusion. These results provide strong evidence to suggest that ILM of the common housefly can provide a successful alternative protein source to FM in broiler diets. PMID- 29452387 TI - OAS1, 2, and 3: Significance During Active Tuberculosis? AB - Evidence to-date points to a detrimental role of the type I IFNs during tuberculosis. The mechanisms underpinning the IFNalphabeta-mediated exacerbation of the disease is unclear. The 2'-5'-oligoadenylate synthetases (OAS), namely OAS1, OAS2 and OAS3 are part of the interferon-induced genes which until now have been synonymous with an anti-viral function. Blood transcriptome profiling has continuously observed their upregulation in a number of gene expression signatures which discriminate active TB from latent TB infection, however the role of the OASs and the effect that their expression has on the pathogenesis and persistence of TB is unknown. Evidence suggests that the OASs exhibit other cellular functions which include the induction of apoptosis, enhancement of IFNalphabeta signalling, immune cell receptor modulation and autophagy. We propose that i) during the late stages of disease, sustained RNaseL expression through OAS activation enhances type I IFN signalling and, ii) that they may exhibit immune-modulatory capabilities. PMID- 29452388 TI - Structural and functional changes in coffee trees after 4 years under free air CO2 enrichment. AB - Background and Aims: Climate forecasts suggest that [CO2] in the atmosphere will continue to increase. Structural and ecophysiological responses to elevated air [CO2] (e[CO2]) in tree species are contradictory due to species-dependent responses and relatively short-term experiments. It was hypothesized that long term exposure (4 year) to e[CO2] would change canopy structure and function of Coffea arabica trees. Methods: Coffee plants were grown in a FACE (free air CO2 enrichment) facility under two air [CO2]: actual and elevated (actual + approx. 200 MUL CO2 L-1). Plants were codified following the VPlants methodology to obtain coffee mock-ups. Plant canopies were separated into three 50 cm thick layers over a vertical profile to evaluate their structure and photosynthesis, using functional-structural plant modelling. Key Results: Leaf area was strongly reduced on the bottom and upper canopy layers, and increased soil carbon concentration suggested changes in carbon partitioning of coffee trees under e[CO2]. Increased air [CO2] stimulated stomatal conductance and leaf photosynthesis at the middle and upper canopy layers, increasing water-use efficiency. Under e[CO2], plants showed reduced diameter of the second-order axes and higher investment in the youngest third to fifth-order axes. Conclusions: The responses of Arabica coffee grown under long-term exposure to e[CO2] integrated structural and functional modifications, which balanced leaf area loss through improvements in leaf and whole-plant photosynthesis. PMID- 29452389 TI - Parity associated with telomere length among US reproductive age women. AB - STUDY QUESTION: Is telomere length related to parity among a nationally representative sample of US reproductive age women? SUMMARY ANSWER: History of live birth was associated with shorter telomere length. WHAT IS KNOWN ALREADY: Shorter telomeres have been linked with a range of chronic health conditions and mortality and parity has been associated with health indicators. However, there is a lack of research on how parity relates to telomere length. STUDY DESIGN, SIZE, DURATION: This nationally representative, cross-sectional study included 1954 women from the National Health and Nutrition Examination Survey, 1999-2002, the only survey period which includes measurement of telomere length. PARTICIPANTS/MATERIALS, SETTING, METHODS: Women aged 20-44 were included. Parity, defined as number of previous live births, was ascertained by questionnaire. Leukocyte telomere length was measured by polymerase chain reaction and reported as a ratio in relation to standard reference DNA (T/S ratio). The relationship between leukocyte T/S ratio and parity was examined using survey weighted linear regression. Models were adjusted for race/ethnicity, age, BMI, income-to-poverty ratio, education, early age at menarche and smoking status. MAIN RESULTS AND THE ROLE OF CHANCE: Among reproductive age women in the US, the adjusted mean leukocyte T/S ratio was 4.2% (95% CI: 0.9, 7.3) shorter in parous compared with nulliparous women. Parity was associated with 116 fewer base pairs (95% CI: 26, 204) on average, using estimated coefficients from the adjusted linear regression models and mean covariate values. LIMITATIONS REASONS FOR CAUTION: This study was cross-sectional and therefore was unable to establish temporality. The dataset lacked information on social factors, stress and fertility status, which may help explain these findings. Only two previous studies have examined this question and our findings should be interpreted with caution. WIDER IMPLICATIONS OF THE FINDINGS: These findings in a nationally representative sample of US reproductive age women suggest that history of live birth may be associated with accelerated cellular aging. The magnitude of the observed association was greater than that of the impact of smoking or obesity on telomere length, suggesting that parity may have an independent influence on cellular aging and warrant further study. STUDY FUNDING/COMPETING INTEREST(S): The study was funded in part by the Undergraduate Research Scholars Program at George Mason University. The authors have no conflicts of interest.

AB - Storing eggs at low temperature prior to incubation is common practice in the broiler hatchery industry; however, prolonged storage (beyond 7 d) is known to increase early embryonic mortality and reduce chick quality and performance. To better understand the basis of this mortality, we previously published milestone criteria to evaluate morphological and cellular properties of the freshly laid embryo. Using these criteria, in the present study we checked the effects of storage at 18 degrees C and 12 degrees C for up to 28 d on hatchability and chick quality. Furthermore, using a 3D high-resolution episcopic microscopy (HREM) imaging system combined with standard and confocal microscopy and cell viability markers, we analyzed the effects of the different storage conditions on embryonic developmental stage, cytoarchitectural properties, mitotic index and cell survival. A total of 1,483 eggs from a young flock were divided in 2 groups, 18 degrees C and 12 degrees C, and stored for 7, 14, 21, and 28 d. Following storage, randomly selected 1,222 eggs were incubated, and the hatched chicks were evaluated for chick quality parameters. Nonhatched eggs were also analyzed to determine the stage of embryonic mortality. The remaining 261 eggs were isolated and analyzed for developmental stage, cytoarchitecture, mitotic index, and cell death following storage. Hatchability rates beyond 7 d of storage at 12 degrees C were significantly improved compared to 18 degrees C, and chick quality remained high. Similar results were obtained for an old flock's eggs (n = 1,350). Analyzing the embryos, at each time point, we found that at 12 degrees C, the developmental progression during storage slows significantly, mitotic index-which at this temperature may indicate mitotic arrest-increases and the rate of early apoptosis is half than at 18 degrees C. Moreover, the HREM system and histological sections showed that embryos stored at 18 degrees C for prolonged times undergo dramatic cytoarchitectural changes that may be maladaptive to resuming normal development after diapause. We thus demonstrate the usefulness of the milestone criteria for predicting and studying the storage conditions that will allow for better performance in hatchery practice.

PMID- 29452392 TI - pBRIT: gene prioritization by correlating functional and phenotypic annotations through integrative data fusion. AB - Motivation: Computational gene prioritization can aid in disease gene identification. Here, we propose pBRIT (prioritization using Bayesian Ridge regression and Information Theoretic model), a novel adaptive and scalable prioritization tool, integrating Pubmed abstracts, Gene Ontology, Sequence similarities, Mammalian and Human Phenotype Ontology, Pathway, Interactions, Disease Ontology, Gene Association database and Human Genome Epidemiology database, into the prediction model. We explore and address effects of sparsity and inter-feature dependencies within annotation sources, and the impact of bias towards specific annotations. Results: pBRIT models feature dependencies and sparsity by an Information-Theoretic (data driven) approach and applies intermediate integration based data fusion. Following the hypothesis that genes underlying similar diseases will share functional and phenotype characteristics, it incorporates Bayesian Ridge regression to learn a linear mapping between functional and phenotype annotations. Genes are prioritized on phenotypic concordance to the training genes. We evaluated pBRIT against nine existing methods, and on over 2000 HPO-gene associations retrieved after construction of pBRIT data sources. We achieve maximum AUC scores ranging from 0.92 to 0.96 against benchmark datasets and of 0.80 against the time-stamped HPO entries, indicating good performance with high sensitivity and specificity. Our model shows stable performance with regard to changes in the underlying annotation data, is fast and scalable for implementation in routine pipelines.

PMID- 29452393 TI - No copper supplementation in a corn-soybean basal diet has no adverse effects on late-phase laying hens under normal and cyclic high temperatures. AB - Over supplementation of copper (Cu) in animal diets may cause serious pollution in soil, water and harvested crops. To minimize the potential pollution, the effects of corn-soybean basal diet with or without supplementation of 8 mg Cu/kg on laying performance, plasma biochemical metabolic indices, and antioxidant status in laying hens were evaluated under normal and cyclic high temperatures. A total of 240 Hy-Line Brown laying hens were randomly allotted to 4 treatments with 6 replicates of 10 hens per replicate according to factorial design involved in 2 temperatures [normal temperature (NT) vs. cyclic high temperature (CHT)] and 2 dietary Cu addition amount [Cu0 (0 mg/kg) vs. Cu8 (8 mg/kg in the form of CuSO4.5H2O)]. The experimental period included 1-week adaptation, 2-week heat stress and 2-week convalescence. The temperatures of NT groups in the same period or any groups during other periods were kept at 26 +/- 2 degrees C except that of CHT groups were 26 +/- 2 degrees C~33 +/- 2 degrees C cyclically during heat stress period. CHT groups increased (P < 0.05) the rectal temperature and plasma glucose content under heat stress, but decreased (P < 0.01) the egg yield at the second week of heat stress and the first week of convalescence, and the plasma triglyceride, uric acid, and triiodothyronine levels under heat stress. Cu8 groups increased (P < 0.05) egg weight at the first week of convalescence, and plasma thyroxin level during the whole convalescence. Interactions between temperature and Cu content existed (P < 0.05) in the laying rate at the first week of convalescence, and the plasma lactic dehydrogenase level under heat stress. Conclusively, the CHT impaired laying performance. The Cu content (10.3 mg/kg) in corn-soybean basal diet might be sufficient for meeting the maintenance and production requirements of late-phase laying hens, and no Cu supplementation had no adverse effects on egg production and antioxidant indices under cyclic high (26 +/- 2 degrees C~33 +/- 2 degrees C) or normal (26 +/- 2 degrees C) temperatures. PMID- 29452394 TI - Treatment of hypertrophic cardiomyopathy caused by cardiospecific variants of Fabry disease with chaperone therapy. PMID- 29452395 TI - Mini-extracorporeal circulation technology, conventional bypass and prime displacement in isolated coronary and aortic valve surgery: a propensity-matched in-hospital and survival analysis. AB - OBJECTIVES: Conventional cardiopulmonary bypass is the most commonly used means of artificial circulation in cardiac surgery. However, it suffers from the effects of haemodilution and activation of inflammatory/coagulation cascades. Prime displacement (PD) can offset haemodilution and mini-extracorporeal technology (MIECT) can offset both. So far, no study has compared all of these modalities together; hence, we compared the outcomes of these 3 modalities at our institution. METHODS: This was a retrospective analysis of our cardiac surgical database. A total of 9626 patients underwent conventional bypass (CB), 3125 patients underwent a modification of CB, called PD, and 904 underwent MIECT. A 1:1 propensity-matching algorithm was employed using IBM SPSS 24 to match (i) 813 MIECT patients with 813 CB patients and (ii) 717 MIECT patients with 717 PD patients. The patients included coronary artery bypass grafting and valve surgery. RESULTS: MIECT had significantly (P < 0.05) longer bypass and cross clamp times compared to CB and PD. MIECT had significantly higher rates of postoperative atrial fibrillation associated with it compared to CB. The mean red cell blood transfusion was significantly lower in the MIECT group compared to the CB group as was the mean platelet transfusion and fresh frozen plasma transfusion. The overall 5-year survival was higher in the MIECT group compared to the CB group (log-rank, P = 0.018). Between the MIECT and the PD groups, we found the incidence of renal failure and gastrointestinal complications to be significantly higher in the PD group compared to the MIECT group. CONCLUSIONS: MIECT has short-term advantages over CB and PD. However, due to the retrospective limitations of the study, including calendar time bias, a multicentre randomized controlled trial comparing all 3 modalities will be beneficial for the larger cardiac community. PMID- 29452396 TI - Changes in access to primary care in Europe and its patterning, 2007-12: a repeated cross-sectional study. AB - Background: The strengthening of primary care (PC) has been encouraged as a strategy to achieve more efficient and equitable health systems. However, the Great Recession may have reduced access to PC. This paper analyses the change in access to PC and its patterning in 28 European countries between 2007 and 2012. Methods: We used data from the 2007 and 2012 waves of the EU-SILC questionnaire (n = 687 170). The dependent variable was the self-reported access to PC ('easy' vs. 'difficult'). We modelled the access to PC as a function of the year and individual socioeconomic and country-level health system variables, using a mixed effects logistic regression, adjusting for sex, age, civil status, country of birth, chronic condition and self-reported health. Additionally, we interacted the year with socioeconomic and country-level variables. Results: The probability of reporting difficult access to PC services was 4% lower in 2012, in comparison with 2007 (OR = 0.96, P < 0.01). People with the lowest educational level (OR = 1.63, P < 0.01), high difficulty to make ends meet (OR = 1.94, P < 0.01) and with material deprivation (OR = 1.25, P < 0.01) experienced a significantly higher likelihood of difficult access. The better access in 2012 was significantly higher in people living in countries with higher health expenditures, a greater number of generalist medical practitioners, and with stronger gatekeeping. Conclusion: Access to PC improved between 2007 and 2012, and this improvement was greater for people living in countries with a higher investment in health and PC. However, the poor access amongst low-SE status people was stable over the period. PMID- 29452397 TI - Cohort Profile: The Singapore Multi-Ethnic Cohort (MEC) study. PMID- 29452398 TI - Predominant patterns of splicing evolution on human, chimpanzee and macaque evolutionary lineages. AB - Although splicing is widespread and evolves rapidly among species, the mechanisms driving this evolution, as well as its functional implications, are not yet fully understood. We analyzed the evolution of splicing patterns based on transcriptome data from five tissues of humans, chimpanzees, rhesus macaques and mice. In total, 1526 exons and exon sets from 1236 genes showed significant splicing differences among primates. More than 60% of these differences represent constitutive-to-alternative exon transitions while an additional 25% represent changes in exon inclusion frequency. These two dominant evolutionary patterns have contrasting conservation, regulation and functional features. The sum of these features indicates that, despite their prevalence, constitutive-to alternative exon transitions do not substantially contribute to long-term functional transcriptome changes. Conversely, changes in exon inclusion frequency appear to be functionally relevant, especially for changes taking place in the brain on the human evolutionary lineage. PMID- 29452399 TI - Response of goose intestinal microflora to the source and level of dietary fiber. AB - Geese are capable of digesting and making use of a high-fiber diet, but the mechanism is not well understood and would be of great significance for the development and utilization of roughage resources. In this study, we investigated the effect of dietary fiber (source: corn stover and alfalfa, included at 5% or 8%) on microflora in goose intestines. We used 35-day-old Carlos geese in which we first studied the influence of fiber ingestion on diet digestibility and immune organ indices of geese and found that high dietary fiber (8% content) significantly increased feed intake, the digestibility of neutral and acid detergent fiber, and thymus, bursa, and spleen size. Subsequently, we investigated the effect of dietary fiber on the microbial flora in the various intestinal segments by high throughput sequencing. The bacterial diversity and relative abundance were significantly affected by the type and amount of dietary fiber fed, including that of cellulolytic bacteria such as Bacteroides, Ruminococcus, Clostridium, and Pseudomonas spp. Finally, we isolated and identified 8 strains with cellulolytic ability from goose intestine and then analyzed their activities in combination. The optimal combination for cellulase activity was Cerea bacillus and Pseudomonas aeruginosa. This study has laid a theoretical and practical foundation for knowledge of the efficient conversion and utilization of cellulose by geese. PMID- 29452400 TI - Sleep quality in well-defined Lyme disease: a clinical cohort study in Maryland. AB - Study Objectives: Lyme disease (LD) is the most common vector-borne disease in the United States. Approximately 5-15 per cent of patients develop postantibiotic treatment symptoms termed post-treatment Lyme disease syndrome (PTLDS). The primary objective of this study is to examine and quantify sleep quality among patients with early LD during the acute and convalescent periods, including among the subset who met criteria for PTLDS. Methods: This paper draws from a clinical cohort study of participants with early LD (n = 122) and a subcohort of individuals who later met criteria for PTLDS (n = 6). Participants were followed for 1 year after antibiotic treatment. The Pittsburgh Sleep Quality Index and standardized measures of pain, fatigue, depressive symptoms, and functional impact were administered at all visits for participants and controls (n = 26). Participants meeting criteria for PTLDS at 1 year post-treatment were compared with a subset of PSQI-defined poor sleeping controls (n = 10). Results: At the pretreatment visit, participants with early LD reported poorer sleep than controls. By 6 months post-treatment, participant sleep scores as a group returned to control levels. Participants with PTLDS reported significantly worse global sleep and sleep disturbance scores and worse fatigue, functional impact, and more cognitive-affective depressive symptoms compared with poor sleeping controls. Conclusions: Participants with early LD experienced poor sleep quality, which is associated with typical LD symptoms of pain and fatigue. In the subset of patients who developed PTLDS, sleep quality remains affected for up to 1 year post-treatment and is commonly associated with pain. Sleep quality should be considered in the clinical picture for LD and PTLDS. PMID- 29452401 TI - Understanding communication breakdown in the outpatient referral process in Latin America: a cross-sectional study on the use of clinical correspondence in public healthcare networks of six countries. AB - An adequate use of referral and reply letters-the main form of communication between primary care (PC) and out-patient secondary care (SC)-helps to avoid medical errors, test duplications and delays in diagnosis. However, it has been little studied to date in Latin America. The aim is to determine the level and characteristics of PC and SC doctors' use of referral and reply letters and to explore influencing factors in public healthcare networks of Argentina, Brazil, Chile, Colombia, Mexico and Uruguay. A cross-sectional study was conducted through a survey of PC and SC doctors working in public healthcare networks (348 doctors per country). The COORDENA questionnaire was applied to measure the frequency of use and receipt of referral and reply letters, quality of contents, timeliness and difficulties in using them. Descriptive analyses were conducted and a multivariate logistic regression model was generated to assess the relationship between frequent use and associated factors. The great majority of doctors claim that they send referral letters to the other level. However, only half of SC doctors (a higher proportion in Chile and Mexico) report that they receive referral letters and <20% of PC doctors receive a reply from specialists. Insufficient recording of data is reported in terms of medical history, tests and medication and the reason for referral. The factor associated with frequent use of the referral letter is doctors' age, while the use of reply letters is associated with identifying PC doctors as care coordinators, knowing them and trusting in their clinical skills, and receiving referral letters. Significant problems are revealed in the use of referral and reply letters which may affect quality of care. Multifaceted strategies are required that foster a direct contact between doctors and a better understanding of the PC-based model. PMID- 29452403 TI - Mechanisms controlling nucleic acid-sensing Toll-like receptors. AB - Nucleic acid (NA)-sensing Toll-like receptors (TLRs) respond to DNA/RNA derived from pathogens and dead cells. Structural studies have revealed a variety of molecular mechanisms by which TLRs sense NAs. Double-stranded RNA and single stranded DNA directly bind to TLR3 and TLR9, respectively, whereas TLR7 and TLR8 bind to nucleosides and oligoribonucleotides derived from RNAs. Activation of ligand-bound TLRs is influenced by the functional status of TLRs. Proteolytic cleavage of NA-sensing TLRs enables ligand-dependent TLR dimerization. Trafficking of ligand-activated TLRs in endosomal and lysosomal compartments is requisite for production of type I interferons. Activation of NA-sensing TLRs is required for the control of viruses such as herpes simplex virus and endogenous retroviruses. On the other hand, excessive activation of NA-sensing TLRs drives disease progression in a variety of inflammatory diseases including systemic lupus erythematosus, heart failure, arthritis and non-alcoholic steatohepatitis. NA-sensing TLRs are targets for therapeutic intervention in these diseases. We here focus on our recent progresses in our understanding of NA-sensing TLRs. PMID- 29452402 TI - Mitotane Monotherapy in Patients With Advanced Adrenocortical Carcinoma. AB - Context: Although mitotane is the only approved drug for the treatment of adrenocortical carcinoma (ACC), data on monotherapy in advanced disease are still scarce. Objective: To assess the efficacy of mitotane in advanced ACC in a contemporary setting and to identify predictive factors. Design and Setting: Multicenter cohort study of three German referral centers. Patients: One hundred twenty-seven patients with advanced ACC treated with mitotane monotherapy. Outcome Measures: Response Evaluation Criteria in Solid Tumors evaluation, progression-free survival (PFS) and overall survival (OS) by Kaplan-Meier method, and predictive factors by Cox regression. Results: Twenty-six patients (20.5%) experienced objective response, including three with complete remission. Overall, median PFS was 4.1 months (range 1.0 to 73) and median OS 18.5 months (range 1.3 to 220). Multivariate analysis indicated two main predictive factors: low tumor burden (<10 tumoral lesions), hazard ratio (HR) for progression of 0.51 (P = 0.002) and for death of 0.59 (P = 0.017); and initiation of mitotane at delayed advanced recurrence, HR 0.35(P < 0.001) and 0.34 (P < 0.001), respectively. Accordingly, 67% of patients with low tumor burden and mitotane initiation >=360 days after primary diagnosis experienced a clinical benefit (stable disease >180 days). Patients who achieved mitotane levels >14 mg/L had significantly longer OS (HR 0.42; P = 0.003). Conclusions: At 20.5% the objective response rate was slightly lower than previously reported. However, >20% of patients experienced long-term disease control at >1 year. In general, patients with late diagnosis of advanced disease and low tumor burden might especially benefit from mitotane monotherapy, whereas patients with early advanced disease and high tumor burden are probably better candidates for combined therapy of mitotane and cytotoxic drugs. PMID- 29452404 TI - Vitamin E and vitamin C supplementation improves antioxidant status and immune function in oxidative-stressed breeder roosters by up-regulating expression of GSH-Px gene. AB - This study aimed to evaluate the effects of vitamin C and vitamin E on antioxidant capacity and immune function in oxidative-stressed breeder roosters. One hundred twenty 45-week-old Lveyang black-boned breeder roosters were randomly assigned to 5 dietary treatments, including negative control group (NC), positive control group (PC), and 3 trial groups, which were fed the diets containing 300 mg/kg VC, 200 mg/kg VE, or 300 mg/kg VC and 200 mg/kg VE (VC+VE). At 47 wk of age, the positive control and trial groups were subcutaneously injected 3 times every other d with dexamethasone (DEX) 4 mg/kg of body weight, the negative control group was injected with saline. The experiment lasted for 35 d. The results showed that at 50 wk of age, average daily feed intake of birds challenged with DEX significantly increased (P < 0.05). During post-stress recovery period (52 wk of age), dietary supplemental VE or VC+VE notably increased body weight under oxidative stress (P < 0.01). Oxidative stress induced by DEX could significantly decrease superoxide dismutase (SOD), IgM, antibody titer of ND and mRNA expression of SOD or glutathion peroxidase activity (GSH Px), increase serous malondialdehyde (MDA) (P < 0.05). Supplementation of VC or VE significantly decreased serous MDA, and increased SOD under oxidative stress (P < 0.05). Supplementation of VC or VE, or their combination significantly increased the relative expression of GSH-Px mRNA when compared to the oxidative stressed control treatment (P < 0.05), whereas did not alleviate the relative expression of SOD mRNA (P > 0.05). Therefore, the results suggest that addition of 300 mg/kg VC, 200 mg/kg VE or their combination could improve antioxidant ability and immune performance in oxidative-stressed breeder roosters through up regulating the expression of GSH-Px gene.

PMID- 29452406 TI - Negative Association Between Sclerostin and INSL3 in Isolated Human Osteocytes and in Klinefelter Syndrome: New Hints for Testis-Bone Crosstalk. AB - Context: The regulation of bone mass by the testis is a well-recognized mechanism, but the role of Leydig-specific marker insulin-like 3 peptide (INSL3) on the most abundant bone cell population, osteocytes, is unknown. In this study, we aimed to investigate the relationship between INSL3 and sclerostin, an osteocyte-specific protein that negatively regulates bone formation. Design: Serum sclerostin and INSL3 levels were evaluated in Klinefelter syndrome (KS) and healthy controls. In vitro effect of INSL3 on sclerostin production was evaluated in human cultured osteocytes. Patients: A total of 103 KS patients and 60 age- and sex-matched controls were recruited. Main Outcome Measures: Serum sclerostin and INSL3 levels were assessed by enzyme-linked immunosorbent assay. Osteocytes were isolated by fluorescence-assisted cell sorting. Sclerostin expression was evaluated by western blot, immunofluorescence, and reverse transcription polymerase chain reaction. Measurement of bone mineral density was done by dual energy X-ray absorptiometry at lumbar spine (L1-L4) and femoral neck. Results: Sclerostin levels were significantly increased in KS subjects, and negatively correlated with INSL3 levels in both cohorts and with bone mineral density in the KS group. Stimulation of cultured osteocytes with INSL3 at 10-7 M significantly decreased both sclerostin messenger RNA and protein expression. Conclusions: We report a negative association between the testicular hormone INSL3 and the osteocytic negative regulator of bone formation, sclerostin. We further explored this association in vitro and showed that INSL3 was able to reduce sclerostin expression. These results add further knowledge on the emerging role of sclerostin as a therapeutic target for osteoporosis treatment. PMID- 29452407 TI - Dietary L-glutamine supplementation improves growth performance, gut morphology, and serum biochemical indices of broiler chickens during necrotic enteritis challenge. AB - Necrotic enteritis (NE) causes significant economic losses in the broiler chicken industry, especially in birds raised without in-feed antibiotics. L-glutamine (Gln) is an amino acid that may compensate for metabolic losses from infection and improve the intestinal development. This study investigated the effects of dietary Gln (10 g/kg) supplementation on growth performance, intestinal lesions, jejunum morphology, and serum biochemical indices of broiler chickens during NE challenge. The study employed a factorial arrangement of treatments with factors: NE challenge, no or yes; dietary Gln inclusion, 0 g/kg in starter (S), d 0 to 10, grower (G) d 10 to 24, and finisher (F) d 24 to 35; 10 g/kg in S, G, F, or 10 g/kg in S, G only. Each treatment was replicated in 6 floor pens with 17 birds per pen as the experimental unit for performance and 2 birds for other measurements. Challenge significantly reduced bird performance, increased incidence of intestinal lesions, and affected intestinal development and serum biochemical indices. Regardless of challenge, Gln supplementation increased gain (P < 0.05), feed intake (P < 0.05), and decreased FCR (P < 0.05) on d 24. On d 35, Gln improved gain (P < 0.05) and FCR (P < 0.001) whereas withdrawing Gln from finisher tended to diminish the beneficial effect on weight gain but not FCR. Dietary Gln reduced lesion scores in the jejunum (P < 0.01) and ileum (P < 0.01) in challenged birds. On d 16, Gln increased villus height to crypt depth ratio in unchallenged birds (P < 0.05) and reduced crypt depth of challenged birds on d 24 (P < 0.05). Regardless of challenge, supplementation with Gln reduced crypt depth on d 16 (P < 0.05), and increased villus height (P < 0.01) and the villus height to crypt depth ratio (P < 0.001) on d 24. Dietary Gln lowered serum uric acid level regardless of challenge (P < 0.05). The current study indicates that dietary Gln alleviates adverse effects of NE and may be useful in antibiotic-free diets.

PMID- 29452409 TI - Recruitment and retention of trainee physicians: a retrospective analysis of the motivations and influences on career choice of trainee physicians. AB - Background: Across the UK, there are vacant physician posts at every level. This increases workload and stress for those who remain, in turn making substantive jobs less attractive. Aim: To understand the influences on career choice and retention in training of current trainee physicians. Methods: An online survey, with a combination of closed and free text questions, was developed to assess factors that affected career choices. This was sent to all core and higher specialty trainees in Scotland and Associate or Collegiate members of the Royal College of Physicians Edinburgh not training in Scotland. Results: A total of 846 trainees responded, 231 of whom were trainee physicians; 161 (70%) of trainee physicians stated that experience prior to their current role had a very positive impact on career choice, particularly positive role modelling and informal career advice. Core trainees were less likely to report enjoying their job than higher specialty trainees with 31 (50%) found to enjoy their job 'always' or 'most of the time' in comparison to 114 (79%). About 181 (78%) of trainees selected through national recruitment of which 77 (42%) were moderately satisfied and 32 (8%) completely satisfied with the process. Uncertainty of job location and inability to demonstrate professional ability were the main complaints. Conclusions: Career choices are influenced by role models and informal careers advice. Efforts must be made to improve the experience trainees, particularly those in core training. Current physicians, both trainees and consultants, have an important role in recruiting the next generation of trainee physicians-this must be supported. PMID- 29452412 TI - The GPCC. PMID- 29452408 TI - Genome-wide association study identifies seven novel susceptibility loci for primary open-angle glaucoma. AB - Primary open-angle glaucoma (POAG) is the leading cause of irreversible blindness worldwide for which 15 disease-associated loci had been discovered. Among them, only 5 loci have been associated with POAG in Asians. We carried out a genome wide association study and a replication study that included a total of 7378 POAG cases and 36 385 controls from a Japanese population. After combining the genome wide association study and the two replication sets, we identified 11 POAG associated loci, including 4 known (CDKN2B-AS1, ABCA1, SIX6 and AFAP1) and 7 novel loci (FNDC3B, ANKRD55-MAP3K1, LMX1B, LHPP, HMGA2, MEIS2 and LOXL1) at a genome-wide significance level (P < 5.0*10-8), bringing the total number of POAG susceptibility loci to 22. The 7 novel variants were subsequently evaluated in a multiethnic population comprising non-Japanese East Asians (1008 cases, 591 controls), Europeans (5008 cases, 35 472 controls) and Africans (2341 cases, 2037 controls). The candidate genes located within the new loci were related to ocular development (LMX1B, HMGA2 and MAP3K1) and glaucoma-related phenotypes (FNDC3B, LMX1B and LOXL1). Pathway analysis suggested epidermal growth factor receptor signaling might be involved in POAG pathogenesis. Genetic correlation analysis revealed the relationships between POAG and systemic diseases, including type 2 diabetes and cardiovascular diseases. These results improve our understanding of the genetic factors that affect the risk of developing POAG and provide new insight into the genetic architecture of POAG in Asians.

PMID- 29452416 TI - Early and Midlife Predictors of Wisdom and Subjective Well-Being in Old Age. AB - Objectives: We explored whether wisdom and well-being in old age are the result of early personality traits related to personality growth or personality adjustment, respectively, or successful human development as outlined by Erikson's stage theory and the life course paradigm. Method: Structural equation models were applied to analyze 60-year longitudinal data of 98 white male Harvard graduates born between 1915 and 1924. Different sets of judges rated the men's childhood and adolescence, early adult personality, and midlife generativity. Items measuring wisdom and well-being in old age were self-assessed. Results: Although wisdom and subjective well-being at age 80 were positively correlated, early life predictors differed. Openness to experiences in early adulthood predicted wisdom 60 years later, whereas greater emotional stability and extraversion predicted subjective well-being. Additionally, old age wisdom could be traced back to psychosocial growth throughout life, facilitated by a supportive childhood, adolescent competence, emotional stability in early adulthood, and generativity at midlife. Discussion: Personality traits indicative of personality adjustment or growth differentially predict late-life well-being and wisdom. Yet a balance between personality adjustment and growth, aided by social support and competence during the formative years, might be required to promote wisdom development throughout life. PMID- 29452417 TI - Fruit production and branching density affect shoot and whole-tree wood to leaf biomass ratio in olive. AB - The amount of shoot stem (i.e., woody part of the shoot) dry matter per unit shoot leaf dry matter (i.e., the shoot wood to leaf biomass ratio) has been reported to be lower in short shoots than in long ones, and this is related to the greater and earlier ability of short shoots to export carbon. This is important in fruit trees, since the greater and earlier carbon export ability of shoots with a lower wood to leaf biomass ratio improves fruit production. This ratio may vary with cultivars, training systems or plant age, but no study has previously investigated the possible effect of fruit production. In this study on two olive cultivars (i.e., Arbequina, with low growth rate, and Frantoio, with high growth rate) subject to different fruit production treatments, we found that at increasing fruit production, shoot length and shoot wood to leaf biomass ratio were proportionally reduced in the new shoots growing at the same time as the fruit. Specifically, fruit production proportionally reduced total new-shoot biomass, length, leaf area and average shoot length. With decreasing shoot length, shoot diameter, stem mass, internode length, individual leaf area and shoot wood to leaf biomass ratio also decreased. This may be viewed as a plant strategy to better support fruit growth in the current year, given the greater and earlier ability of short shoots to export carbon. Moreover, at the whole-tree level, the percentage of total tree biomass production invested in leaves was closely correlated with branching density, which differed significantly across cultivars. By branching more, Arbequina concentrates more shoots (thus leaves) per unit of wood (trunk, branches and root) mass, decreasing wood to leaf biomass ratio at the whole-tree level. Therefore, while, at the shoot level, shoot length determines shoot wood to leaf biomass ratio, at the canopy level branching density is also an important determinant of whole-tree wood to leaf biomass ratio. Whole-tree wood to leaf biomass ratio is likely to affect the canopy's ability to export carbon (i.e., towards fruits), as shoot wood to leaf biomass ratio affects the carbon export ability of the shoot. PMID- 29452418 TI - PHF20 collaborates with PARP1 to promote stemness and aggressiveness of neuroblastoma cells through activation of SOX2 and OCT4. AB - The differentiation status of neuroblastoma (NB) strongly correlates with its clinical outcomes; however, the molecular mechanisms driving maintenance of stemness and differentiation remain poorly understood. Here, we show that plant homeodomain finger-containing protein 20 (PHF20) functions as a critical epigenetic regulator in sustaining stem cell-like phenotype of NB by using CRISPR/Cas9-based targeted knockout (KO) for high-throughput screening of gene function in NB cell differentiation. The expression of PHF20 in NB was significantly associated with high aggressiveness of the tumor and poor outcomes for NB patients. Deletion of PHF20 inhibited NB cell proliferation, invasive migration, and stem cell-like traits. Mechanistically, PHF20 interacts with poly(ADP-ribose) polymerase 1 (PARP1) and directly binds to promoter regions of octamer-binding transcription factor 4 (OCT4) and sex determining region Y-box 2 (SOX2) to modulate a histone mark associated with active transcription, trimethylation of lysine 4 on histone H3 protein subunit (H3K4me3). Overexpression of OCT4 and SOX2 restored growth and progression of PHF20 KO tumor cells. Consistently, OCT4 and SOX2 protein levels in clinical NB specimens were positively correlated with PHF20 expression. Our results establish PHF20 as a key driver of NB stem cell-like properties and aggressive behaviors, with implications for prognosis and therapy. PMID- 29452420 TI - Gut Microbiomics-A Solution to Unloose the Gordian Knot of Biological Effects of Ionizing Radiation. AB - The Chernobyl and Fukushima nuclear accidents have called forth a growing body of research on their biological aftermaths. A variety of wild organisms, including primates, birds, fish, insects, and worms are being studied in the affected areas, with emerging morphological, physiological, and genetic aberrations ascribed to ionizing radiation. Despite the effort in surveying Chernobyl and Fukushima wildlife, little is known about the microorganisms associated with these radiation-contaminated animals. The microbiota, especially the gut commensal, plays an important role in shaping the metabolic reservoir and immune system of the host, and is sensitive to a wide array of environmental factors, including ionizing radiation. Humans and limited numbers of laboratory species have been the main subjects of microbiome studies, however, a more practical insight on host-gut microbiota dynamics under environmental impact should be explored in natural habitats. In this analysis, we introduced a working model explaining possible mechanisms of ionizing radiation on the gut microbiota, with an evaluation of the gut microbiota as a potential biomarker for exposure to ionizing radiation. PMID- 29452419 TI - Temozolomide-associated hypermutation in gliomas. AB - Low-grade gliomas cause considerable morbidity and most will recur after initial therapy. At recurrence, low-grade gliomas can undergo transformation to high grade gliomas (grade III or grade IV), which are associated with worse prognosis. Temozolomide (TMZ) provides survival benefit in patients with glioblastomas, but its value in patients with low-grade gliomas is less clear. A subset of TMZ treated, isocitrate dehydrogenase-mutant, low-grade astrocytomas recur as more malignant tumors with thousands of de novo, coding mutations bearing a signature of TMZ-induced hypermutation. Preliminary studies raise the hypothesis that TMZ induced hypermutation may contribute to malignant transformation, although with highly variable latency. On the other hand, hypermutated gliomas have radically altered genomes that present new opportunities for therapeutic intervention. In light of these findings and the immunotherapy clinical trials they inspired, how do patients and providers approach the risks and benefits of TMZ therapy? This review discusses what is known about the mechanisms and consequences of TMZ induced hypermutation and outstanding questions regarding its clinical significance. PMID- 29452421 TI - The Short Cosyntropin Test Revisited: New Normal Reference Range Using LC-MS/MS. AB - Background: The cosyntropin test is used to diagnose adrenal insufficiency (AI) and nonclassical congenital adrenal hyperplasia (NCCAH). Current cutoffs for cortisol and 17-hydroxyprogesterone (17-OHP) are derived from nonstandardized immunoassays. Liquid chromatography tandem mass spectrometry (LC-MS/MS) offers direct measurement of steroids, prompting the need to re-establish normal ranges. Objective: The goal of this study was to define cutoff values for cortisol and 17 OHP in serum by LC-MS/MS 30 and 60 minutes after intravenous administration of 250 ug tetracosactide acetate to healthy volunteers and to compare the results with LC-MS/MS with routine immunoassays. Methods: Cosyntropin testing was performed in healthy subjects (n = 138) and in patients referred for evaluation of adrenocortical function (n = 94). Steroids were assayed by LC-MS/MS and compared with two immunoassays used in routine diagnostics (Immulite and Roche platforms). The cutoff level for cortisol was defined as the 2.5% percentile in healthy subjects not using oral estrogens (n = 121) and for 17-OHP as the 97.5% percentile. Results: Cortisol cutoff levels for LC-MS/MS were 412 and 485 nmol/L at 30 and 60 minutes, respectively. Applying the new cutoffs, 13 of 60 (22%) subjects who had AI according to conventional criteria now had a normal test result. For 17-OHP, the cutoff levels were 8.9 and 9.0 nmol/L at 30 and 60 minutes, respectively. Conclusions: LC-MS/MS provides cutoff levels for cortisol and 17-OHP after cosyntropin stimulation that are lower than those based on immunoassays, possibly because cross-reactivity between steroid intermediates and cortisol is eliminated. This reduces the number of false-positive tests for AI and false-negative tests for NCCAH. PMID- 29452422 TI - Asynchronous and pathological windows of implantation: two causes of recurrent implantation failure. AB - STUDY QUESTION: Is endometrial recurrent implantation failure (RIF) only a matter of an asynchronous (displaced) window of implantation (WOI), or could it also be a pathological (disrupted) WOI? SUMMARY ANSWER: Our predictive results demonstrate that both displaced and disrupted WOIs exist and can present independently or together in the same RIF patient. WHAT IS KNOWN ALREADY: Since 2002, many gene expression signatures associated with endometrial receptivity and RIF have been described. Endometrial transcriptomics prediction has been applied to the human WOI in two previous studies. One study describes endometrial RIF to be the result of a temporal displacement of the WOI. The other indicates that endometrial RIF can also result from a molecularly disrupted WOI without temporal displacement. STUDY DESIGN, SIZE, DURATION: Retrospective analysis was undertaken to compare WOI endometrial transcriptomics predictions in controls (n = 72) and RIF patients (n = 43). RIF was clinically designated by the absence of implantation after four or more transfers of high quality embryos or after the placement of 10 or more embryos in multiple transfers. Endometrial tissue samples were collected from LH + 5 to LH + 8. We compared the two molecular causes of RIF to signatures currently described in the literature. We propose a new transcriptomic RIF taxonomy to fill the gap between the two hypotheses and to guide the development of clinical detection and determination of both types of RIF. PARTICIPANTS/MATERIALS, SETTING, METHODS: Utilizing 115 gene expression profiles, two different predictive designs were developed: one considering RIF versus controls removing menstrual cycle timing, called the disrupted or pathological model, and another stratifying the WOI in transcriptomic profiles related to timing for predicting displacements. The predictive value of each model was compared between all signatures selected. We propose a new genomic approach that distinguishes between both types of RIF in the same sample cohort. MAIN RESULTS AND THE ROLE OF CHANCE: From the 16 signatures analysed, we clearly predicted two causes of RIF-both a displaced WOI and an on-time but pathologically disrupted WOI. A high predictive value related to WOI profiles associated with menstrual cycle timing was found in most of the signatures. Specifically, 69% of the signatures analysed presented an accuracy higher than expected by chance in a range from 0.87 to 0.97. Displacements and disruptions were not molecularly independent, as some signatures were moderately associated with both causes. The gene and functional comparison between signatures revealed that they were not similar, although we did find functions in common and a cluster of moderate functional concordance between some of the signatures that predicted displacements (the highest Cohen's Kappa index were between 0.55 and 0.62 depending on the functional database). We propose a new transcriptomic RIF taxonomy to fill the gap between these prior studies and to establish methodology for detecting and distinguishing both types of RIF in clinical practice. Our findings indicate these two phenotypes could present independently or together in the same RIF patient. RIF patients designated by clinical criteria have been stratified transcriptomically as 18.6% with only a displaced WOI, 53.5% with a displaced and pathological WOI, 23.3% with only a disrupted WOI, and 4.7% could be a clinical RIF with non-endometrial origin. The new RIF transcriptomic taxonomy avoids menstrual cycle timing as a confounding variable that should be controlled for, distinguishing clearly between a disrupted and a displaced WOI for precision medicine in RIF. LIMITATIONS REASONS FOR CAUTION: The main objective of this study was to use transcriptomics to detect both RIF causes and to understand the role of transcriptomic signatures in these phenotypes. The predictive value in absolute terms for each signature was not indicative in these prediction designs; instead, the comparison between signatures was most important for prediction capability in the same sample cohort for both RIF causes. Clinical follow up of the RIF taxonomies proposed has not been analysed in this study, so further prospective clinical studies are necessary to determine the prevalence and penetrance of these phenotypes. WIDER IMPLICATIONS OF THE FINDINGS: The main insight from this study is a new understanding of RIF taxonomy. Understanding how to classify RIF patients to distinguish clinically between a patient who could benefit from a personalized embryo transfer day and a patient with a disrupted WOI will enable identification and stratification for the research and development of new treatments. In addition, we demonstrate that basic research designs in endometrial transcriptomics cause masking of the study variable by the menstrual cycle timing.

PMID- 29452423 TI - Anti-citrullinated alpha enolase antibodies, interstitial lung disease and bone erosion in rheumatoid arthritis. AB - Objectives: RA is an articular chronic inflammatory disease that in a subgroup of patients can also present with extra-articular manifestations (EAMs). Despite intense investigation on this topic, reliable biomarkers for EAMs are lacking. In recent years several ACPAs, including those targeting anti-citrullinated alpha enolase peptide-1 (anti-CEP-1), have been identified in patients with RA. Data about the ability of anti-CEP-1 to predict the development of erosive disease are confliciting and no evidence concerning their possible association with EAMs in RA is currently available. The aim of this study was to investigate the prevalence and significance of anti-CEP-1 with regard to the association with erosive disease and EAMs in a large cohort of patients with RA. Methods: Anti-CCP and anti-CEP-1 antibodies have been assessed on serum samples of RA patients, healthy donors and patients with SpA using commercially available ELISA kits. Results: Anti-CEP-1 antibodies are detectable in over 40% of RA patients and are associated with erosive RA and with RA-associated interstitial lung disease (ILD). Conclusion: Anti-CEP-1 antibodies may represent a useful biomarker for RA associated ILD and erosive disease to be employed in clinical practice.

AB - Fine-root (<=2 mm) demographics change as forests age, but the direction and extent of change are unknown. Knowledge of the change and understanding of causes will improve predictions of climate change impacts. We used minirhizotrons at three young and three mature balsam fir (Abies balsamea (L.) Mill.) sites to measure median lifespan (MLS) for each site and for annual cohorts. We computed turnover rate from the inverse of MLS (Tinv) and calculated a second turnover rate (T) from annual mortality, annual production and previous year-end standing crop. Median lifespan at mature sites (436 days) was half that at young sites (872 days). Median lifespan of annual cohorts varied widely at all sites. Age class distributions of fine roots seen by minirhizotrons changed with increasing years of observation, with older age classes accumulating more slowly at mature sites. Our findings highlight the need to determine whether the proportional contributions of absorbing and transporting fine roots to annual production and their median lifespans change during stand development. Due to its variation among annual cohorts, we believe robust estimates of MLS at our sites require 5-7 years of observation, and reliable estimates of Tinv are reached earlier than T. PMID- 29452425 TI - Clinical evidence on dietary supplementation with chia seed (Salvia hispanica L.): a systematic review and meta-analysis. AB - Context: Chia seed is a popular dietary supplement, taken mainly for its high content of alpha-linolenic acid, vegetable protein, and dietary fiber, yet information about its clinical effects is lacking. Objective: This review aims to summarize the clinical evidence regarding the use of chia seed for a wide variety of health conditions. Data Sources: A number of databases, including PubMed and Embase, were searched systematically. Study Selection: Randomized controlled trials that assessed the clinical effects of chia seed consumption in human participants were included. The quality of trials was assessed using the Cochrane Risk of Bias Tool. Data Extraction: Data on study design, blinding status, characteristics of participants, chia seed intervention, comparator, clinical assessment, duration of intake, interval of assessment, and study funding status were extracted. Meta-analysis was performed. Results: Twelve trials were included. Participants included healthy persons, athletes, diabetic patients, and individuals with metabolic syndrome. Pooling of results showed no significant differences except for the following findings of subgroup analysis at higher doses of chia seed: (1) lower postprandial blood glucose level (mean difference [MD] of -33.95 incremental area under the curve [iAUC] [mmol/L * 2 h] [95%CI, 61.85, -6.05] and -51.60 iAUC [mmol/L * 2 h] [95%CI, -79.64, -23.56] at medium doses and high doses, respectively); (2) lower high-density lipoprotein in serum (MD of -0.10 mmol/L [95%CI, -0.20, -0.01]); and (3) lower diastolic blood pressure (MD of -7.14 mmHg [95%CI, -11.08, -3.19]). The quality of all evidence assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was low or very low. All trials employed only surrogate markers as outcomes. Conclusions: Future trials with improved methodological quality, well-described clinical events, and validated surrogate markers as outcomes are needed to support the potential health benefits of chia seed consumption.

AB - Open Access (OA) is widely considered a breakthrough in the history of academic publishing, rendering the knowledge produced by the worldwide scientific community accessible to all. In numerous countries, national governments, funding institutions and research organisations have undertaken enormous efforts to establish OA as the new publishing standard. The benefits and new perspectives, however, cause various challenges. This essay addresses several issues, including that OA is deeply embedded in the logic and practices of data capitalism. Given that OA has proven an attractive business model for commercial publishers, the key predictions of OA-advocates, namely that OA would liberate both scientists and tax payers from the chains of global publishing companies, have not become true. In its conclusion, the paper discusses the opportunities and pitfalls of non-commercial publishing. PMID- 29452427 TI - Effect of Routine, Screening Head Ultrasounds on Clinical Interventions for Premature Infants. AB - OBJECTIVE: This article assesses whether routine, screening head ultrasound (HUS) studies performed at 7 to 14 postnatal days for premature infants are followed by clinical interventions. STUDY DESIGN: This retrospective cohort study included all inborn infants delivered at < 30 weeks' gestational age (GA) between January 1, 2012 and December 31, 2015 at a single center who had a routine, screening HUS performed between 7 and 14 postnatal days (n = 303). We defined "clinical intervention" as a 7 to 14 postnatal day HUS that was followed by neurosurgical intervention prior to a 36- to 40-week postmenstrual age (PMA) HUS or elective withdrawal of critical care within 30 days of a positive HUS finding. RESULTS: Four infants (1.3%) had neurosurgical intervention prior to a 36- to 40-week PMA HUS; all four had a diagnostic HUS performed prior to postnatal day 7 to assess for an intraventricular hemorrhage (IVH) due to clinical instability. No infant had critical care electively withdrawn following a 7 to 14 postnatal day HUS. CONCLUSION: Clinical intervention rarely followed routine, screening HUS studies performed at 7 to 14 postnatal days for inborn infants delivered at < 30 weeks' GA. In no case did clinical intervention related to HUS results occur when a 7 to 14 postnatal day HUS was the initial HUS performed. PMID- 29452428 TI - Illness Severity Predicts Death and Brain Injury in Asphyxiated Newborns Treated with Hypothermia. AB - OBJECTIVE: To determine if illness severity during the first days of life predicts adverse outcome in asphyxiated newborns treated with hypothermia. STUDY DESIGN: We conducted a retrospective cohort study of asphyxiated newborns treated with hypothermia. Illness severity was calculated daily during the first 4 days of life using the Score for Neonatal Acute Physiology II (SNAP-II score). Adverse outcome (death and/or brain injury) was recorded. Differences in SNAP-II scores between the newborns with and without adverse outcome were assessed. RESULT: 214 newborns were treated with hypothermia. The average SNAP-II score over the first 4 days of life was significantly worse in newborns developing adverse outcome. The average SNAP-II score was an excellent predictor of death (area under the curve [AUC]: 0.93; p < 0.001) and a fair predictor of adverse outcome (AUC: 0.73; p < 0.001). The average SNAP-II score remained a significant predictor of adverse outcome (odds ratio [95% confidence interval]: 1.08 [1.04 1.12]; p < 0.001), after adjusting for baseline characteristics, degree of initial asphyxial event, and initial severity of encephalopathy. CONCLUSION: In asphyxiated newborns treated with hypothermia, not only the initial asphyxial event but also the illness severity during the first days of life was a significant predictor of death or brain injury.

PMID- 29452438 TI - Algorithmic Approach for Intraoperative Salvage of Venous Congestion in DIEP Flaps. AB - BACKGROUND: Flap congestion is a frequently described intraoperative complication during autologous breast reconstruction with abdominal perforator flaps, which, if not addressed, can lead to detrimental results such as flap failure. Here, we describe our institution's algorithm of intraoperative salvage of congested flaps and present their outcomes. PATIENTS AND METHODS: All patient charts from 2002 to 2016 of a single plastic surgeon were reviewed for patients who underwent deep inferior epigastric perforator flap breast reconstruction resulting in 602 patients and 831 flaps. Of those, 38 women (6.3%) with 40 congested flaps (4.8%) were included in this study. Based on the algorithm guiding the selection of additional venous anastomosis, the patients' surgical details, outcomes, as well as their demographic characteristics are evaluated. RESULTS: Average age and body mass index of our cohort were 47.0 +/- 8.0 years and 26.1 +/- 3.9, respectively. Ten patients (26.3%) were current or former smokers while 20 (52.6%) required external radiation. Thirty-two congested flaps (80.0%) were predominantly salvaged with a superficial inferior epigastric vein (SIEV)-to-deep inferior epigastric vein (comitante) anastomosis. An SIEV-to internal mammary vein comitante anastomosis was the second favorite option (5 flaps, 12.5%). Five patients suffered minor complications within a mean follow-up of 18.8 +/- 12.3 months without flap failure, bleeding, or infection. CONCLUSIONS: Venous flap congestion is an uncommon intraoperative intricacy during free tissue transfer for autologous breast reconstruction. Our proposed algorithm primarily recommends adding an additional venous anastomosis between the superficial and deep drainage system and results and favorable outcomes without major complications. PMID- 29452439 TI - Assessment of Function after Free Tissue Transfer to the Lower Extremity for Chronic Wounds Using the Lower Extremity Functional Scale. AB - BACKGROUND: Free tissue transfer is one option for preservation of form and function in the native limb, in the setting of soft tissue paucity. However, the data on patient functionality after microvascular intervention is inconsistently reported. The Lower Extremity Function Scale (LEFS) measures patient-reported difficulty in carrying out 20 physical activities, on a Likert scale, the sum of which correlates with descriptive functional stages of 1-5. We assess limb functionality in this cohort of microvascular patients using the LEFS survey. METHODS: A retrospective chart review was conducted at a single academic medical center of 101 consecutive free flaps, from 2011 to 2016. Of the flaps that met inclusion criteria, 39 had completed LEFS surveys. Mean LEFS scores were calculated, and the effects of risk factors such as diabetes, age, and smoking status were analyzed. RESULTS: The mean LEFS score after free tissue transfer was 50.3 (SD +/- 21.1), with a mean follow up survey time of 3.0 years (SD +/- 1.3). The score correlated with Stage 4 function, or "independent community ambulation," and age was the only demographic factor associated with decreased functionality in this group. This is compared with mean LEFS score of 43.1 (SD +/ 18.4) in cohort of 55 below knee amputations (BKAs), and 38.3 (SD +/- 14.9) in 28 above knee amputations (AKAs), both correlating with Stage 3 function: "limited community ambulation." CONCLUSIONS: Functional outcomes scores such as the LEFS demonstrate that patients can obtain an adequate level of functionality for independent community activity after free tissue transfer, although functional improvement diminishes with age. PMID- 29452440 TI - Operative Time and Flap Failure in Unilateral and Bilateral Free Flap Breast Reconstruction. AB - BACKGROUND: There is an increasing trend toward bilateral breast reconstruction. Using the National Surgical Quality Improvement Program (NSQIP) database, we sought to understand the association between unilateral and bilateral free flap breast reconstruction and operative time and flap failure. METHODS: We selected a cohort of patients undergoing free flap breast reconstruction using the 2005 to 2010 NSQIP database. Cases were divided into unilateral and bilateral reconstruction. Subgroup analyses were performed dividing cases into delayed and immediate reconstruction. The effect of patient characteristics including age, body mass index (BMI), history of diabetes, and the American Society of Anesthesiologists' classification on operative time and flap failure was examined using univariable and multivariable regression models. Rates and odds ratios (OR) were reported using the multivariable gamma and logistic regression models, respectively. RESULTS: There were 691 free flap breast reconstructions performed in the cohort and 29.1% were bilateral cases. There was a 78-minute increase in the median operative time when comparing unilateral and bilateral reconstruction (p = 0.005). Patients undergoing bilateral reconstructions were generally younger and had fewer comorbidities compared with unilateral reconstructions. There was no significant association between bilateral reconstruction and flap failure. Immediate bilateral reconstructions had a significant increase in median operative time compared with immediate unilateral reconstructions (563 versus 480 minutes, p = 0.002) but no significant increase in operative time was noted when comparing delayed unilateral and delayed bilateral reconstructions. Prolonged operative time was associated with flap failure after adjusting for age and BMI (OR 1.17, p < 0.001). CONCLUSIONS: Bilateral free flap breast reconstruction can be performed safely despite an increase in operative time when compared with unilateral reconstruction.

AB - BACKGROUND: Perioperative pain, increased sympathetic tone, and peripheral vasospasm may be safely managed with regional nerve blockade during microvascular reconstruction in the lower extremity. Limited reports exist in this setting; therefore, we evaluated our use of peripheral nerve catheters (PNCs) during microvascular limb salvage to determine safety and efficacy for both patient and flap. METHODS: A single-institution, retrospective review of a prospectively maintained database on all patients with lower extremity free tissue transfers between 2012 and 2017 was completed. Patients were matched into groups based on PNC utilization. The use of intravenous narcotics including patient-controlled analgesia (PCA), oral narcotics, antiemetics, length of stay (LOS), associated pain scores, flap-related performance, and patient morbidity was recorded. RESULTS: Of 48 patients who underwent lower extremity free tissue transfer, 35 satisfied criteria for comparison. Of these, PNC was utilized in 83%. The mean pain score in the immediate postoperative period was 3.84 +/- 2.47 (10-point Likert scale). PCA and narcotic use were decreased in the PNC group, and no adverse effects of the catheter were identified. Microsurgical outcomes were not adversely affected in comparison. CONCLUSION: PNC utilization for lower extremity free flap transfer significantly reduced concurrent narcotic use and attained a shorter LOS. The technique provided for safe analgesia during lower extremity free flap reconstructions satisfying the microsurgeon and the anesthesiologist. PMID- 29452442 TI - Simplifying Arterial Coupling in Microsurgery-A Preclinical Assessment of an Everter Device to Aid with Arterial Anastomosis. AB - BACKGROUND: A novel arterial everter device was engineered to simplify microvascular coupling of arteries by reliably securing the stiff, muscular wall of arteries over coupler pins. We compare microvascular coupling with the everter device to manual suturing for arterial anastomoses in a live large animal model. MATERIALS AND METHODS: In this preliminary study, bilateral external femoral arteries of five male swine were exposed and sharply divided. Arteries were anastomosed using either interrupted sutures (n = 5) or the everter device and Synovis Coupler (n = 5). The efficiency in engaging coupler pins, the time taken to perform the anastomosis, and vessel patency immediately post-op and at 1-week postanastomosis were evaluated. Vessel wall injury and luminal stenosis were compared between groups using histomorphometric analyses. RESULTS: On an average, 80% of coupler pins engaged the vessel walls after a single pass of the everter. The average time to perform the anastomosis was significantly less when using the everter/coupler compared with manual suturing (6:35 minutes versus 25:09 minutes, p < 0.001). Immediately post-op, 100% patency was observed in both groups. At 1 week post-op, four of five (80%) of coupled arteries and all five (100%) of hand-sewn arteries were patent. The degree of arterial wall injury, neointimal formation, and luminal stenosis for patent arteries were similar between groups. CONCLUSIONS: Successful arterial anastomoses using the everter device with the Synovis Coupler was easier and significantly more efficient when compared with a standard hand-sewn technique. Both techniques had acceptable patency rates and similar effects on the vessel wall and intima. PMID- 29452443 TI - Gender Comparison of Medical Student Microsurgical Skills in a Laboratory Model. AB - BACKGROUND: Perceived gender-related differences in surgical skills could limit opportunities available for any aspiring surgeon. There should be more available literature and logical analysis of these observations. The objective of this study is to evaluate the microsurgical skills of male and female medical students using a standard scale in the laboratory. METHODS: This study included medical students enrolled in the Kaohsiung Chang Gung Memorial Hospital from 2002 to 2015 who were evaluated by a senior consultant for their microsurgical skills. A standard numeric scale was used to evaluate their suturing technique after basic microsurgical training. Differences in the scores between male and female medical students were evaluated using statistical analysis. RESULTS: A total of 578 medical students were included in the study. There were 393 males (68%) and 185 females (32%). Using statistical analysis, there is no significant difference in the distribution of scores (p-Value = 0.78) and mean scores (p-Value = 0.75) between the two groups. CONCLUSIONS: This study shows that microsurgical skills of male and female medical students are similar. Equal opportunities in the eventual pursuit of the surgical specialties should be available regardless of gender. PMID- 29452444 TI - Risk of Venous Thrombosis in Antithrombin Deficiency: A Systematic Review and Bayesian Meta-analysis. AB - Antithrombin deficiency is a strong risk factor for venous thromboembolism (VTE), but the absolute risk of the first and recurrent VTE is unclear. The objective of this paper is to establish the absolute risks of the first and recurrent VTE and mortality in individuals with antithrombin deficiency. The databases Embase, Medline Ovid, Web of Science, the Cochrane Library, and Google Scholar were systematically searched for case-control and cohort studies. Bayesian random effects meta-analysis was used to calculate odds ratios (ORs), absolute risks, and probabilities of ORs being above thresholds. Thirty-five publications were included in the systematic review and meta-analysis. Based on 19 studies, OR estimates for the first VTE showed a strongly increased risk for antithrombin deficient individuals, OR 14.0; 95% credible interval (CrI), 5.5 to 29.0. Based on 10 studies, meta-analysis showed that the annual VTE risk was significantly higher in antithrombin-deficient than in non-antithrombin-deficient individuals: 1.2% (95% CrI, 0.8-1.7) versus 0.07% (95% CrI, 0.01-0.14). In prospective studies, the annual VTE risk in antithrombin deficient individuals was as high as 2.3%; 95% CrI, 0.2-6.5%. Data on antithrombin deficiency subtypes are very limited for reliable risk-differentiation. The OR for recurrent VTE based on 10 studies was 2.1; 95% CrI, 0.2 to 4.0. The annual recurrence risk without long term anticoagulant therapy based on 4 studies was 8.8% (95% CrI, 4.6-14.1) for antithrombin-deficient and 4.3% (95% CrI, 1.5-7.9) for non-antithrombin-deficient VTE patients. The probability of the recurrence risk being higher in antithrombin deficient patients was 95%. The authors conclude that antithrombin deficient individuals have a high annual VTE risk, and a high annual recurrence risk. Antithrombin deficient patients with VTE require long-term anticoagulant therapy. PMID- 29452445 TI - Suppressive Role of Tissue Factor Pathway Inhibitor-alpha in Platelet-Dependent Fibrin Formation under Flow Is Restricted to Low Procoagulant Strength. AB - Tissue factor pathway inhibitor-alpha (TFPI-alpha) is a Kunitz-type serine protease inhibitor, which suppresses coagulation by inhibiting the tissue factor (TF)/factor VIIa complex as well as factor Xa. In static plasma-phospholipid systems, TFPI-alpha thus suppresses both factor Xa and thrombin generation. In this article, we used a microfluidics approach to investigate how TFPI-alpha regulates fibrin clot formation in platelet thrombi at low wall shear rate. We therefore hypothesized that the anticoagulant effect of TFPI-alpha in plasma is a function of the local procoagulant strength-defined as the magnitude of thrombin generation under flow, due to local activities of TF/factor VIIa and factor Xa. To test this hypothesis, we modulated local coagulation by microspot coating of flow channels with 0 to 100 pM TF/collagen, or by using blood from patients with haemophilia A or B. For blood or plasma from healthy subjects, blocking of TFPI alpha enhanced fibrin formation, extending from a platelet thrombus, under flow only at <2 pM coated TF. This enhancement was paralleled by an increased thrombin generation. For mouse plasma, genetic deficiency in TFPI enhanced fibrin formation under flow also at 0 pM TF microspots. On the other hand, using blood from haemophilia A or B patients, TFPI-alpha antagonism markedly enhanced fibrin formation at microspots with up to 100 pM coated TF. We conclude that, under flow, TFPI-alpha is capable to antagonize fibrin formation in a manner dependent on and restricted by local TF/factor VIIa and factor Xa activities.

AB - BACKGROUND: In the treatment of center-involving diabetic macular edema, despite initial therapy with an anti-VEGF compound, an insufficient response may occur. Further therapy options include a switch of anti-VEGF products or to corticosteroid implants, such as Fluocinolone acetonide or Dexamethasone. OBJECTIVES: Firstly, to investigate systematically which evidence-based study data are available describing the efficacy of in-label treatments after primary anti-VEGF treatment, secondly, to investigate which costs go along for the healthcare provider. METHODS: A systematic literature review (SLR) for randomized controlled trials (RCT) was performed in Medline and Embase. A short-term cost cost model was built in MS Excel with a 3 year time horizon to compare in-label intravitreal options Ranibizumab (Lucentis(r)), Aflibercept (Eylea(r)), Fluocinolone acetonide implant (Iluvien(r)), and Dexamethasone implant (Ozurdex(r)). Cost components comprised of drug and injection costs, optical coherence tomography (OCT) procedures, and adverse events such as endophthalmitis, IOP-lowering drugs and surgery and cataract surgery. RESULTS: A total of 42 publications of 20 RCTs were identified. No study had a clearly defined population after first line anti-VEGF treatment, thus no direct efficacy comparison was possible. In the short-term cost-cost model total costs were 17,542 ? for Ranibizumab, 15,896 ? for Aflibercept, 10,826 ? for Fluocinolone acetonide implant and 12,365 ? for Dexamethasone implant. For all treatment regimens, drug costs were the predominant cost component, followed by injection costs (with variations dependent on the specific drug) and OCT costs. In the uni- and multivariate sensitivity analyses, the results obtained were robust to changes of model inputs. CONCLUSIONS: In summary, the short-term cost-cost comparison demonstrates that steroid implants can provide significant cost savings versus in-label anti-VEGF treatment for center-involving diabetic macular edema. Single application of the long-lasting Fluocinolone acetonide implant is the most cost-efficient in-label treatment option. PMID- 29452451 TI - Botulinum Toxin for the Treatment of Cyclic Strabismus in Children: Three Case Reports. AB - Cyclic strabismus is a rare disease of unknown origin. If untreated, it leads to manifest strabismus with the risk of amblyopia in children. Treatment is generally surgical. Here we report on three children in whom cyclic esotropia was successfully treated with one bimedial injection of 5 IU Botox(r). All patients remained orthotropic with good stereo functions at the last follow-ups at 16, 11, and 8 months. Botulinum toxin offered a minimally invasive treatment option in these patients. PMID- 29452452 TI - [Effectivity and Safety of a Modified Tip Design in Torsional Phacoemulsification]. AB - BACKGROUND: Torsional mode phacoemulsification results in more effective fragmentation of the nucleus due to a different movement of the phacotip. In this clinical study, we investigated the influence of a modified tip design and active fluidics on the efficacy of phacoemulsification and safety for the corneal endothelium. MATERIAL AND METHODS: We conducted a prospective randomized 2 : 1 study in which 40 patients were operated on with the mini-flared Kelman Tip using the Infiniti(r) System (group 1), and 20 patients were operated on with the Intrepid(r) Balanced Tip and the Centurion(r) System. We analyzed the intraoperative cumulative dissipated energy and also the density of the corneal endothelium measured with an endothelial microscope (CEM 530, Nidek) pre- and postoperatively. RESULTS: Both groups did not differ preoperatively in age, sex, axial length of the globe or corneal endothelium cell density nor cataract density (LOCS3). All surgeries were uneventful. The cumulative dissipated energy in group 1 (mini-flared Kelman tip, Infiniti System) was 38% higher than in group 2 (balanced tip, Centurion System; p < 0.05). The endothelial cell loss was 8% in group 1 and 10.3% in group 2 (p > 0.05). The cell size (polymegathism) increased in both groups significantly with + 37 um in group 1 (p < 0.05) und + 54 um in group 2 (p < 0.05). There was no statistically significant difference between both groups (p > 0.05). The number of hexagonal cells (pleomorphism) and corneal thickness did not differ in both groups either pre- nor postoperatively. CONCLUSIONS: Compared to torsional phacoemulsification with a mini-flared Kelman Tip and gravity fluidics, torsional phacoemulsification with a modified tip design and active fluidics is 38% more effective regarding the cumulative dissipated energy. Endothelial cell loss occurs to a similar extend using both systems. The postoperative changes in cell size (polymegathism), number of hexagonal cells (pleomorphism) and corneal thickness (pachymetry) were similar among both systems. We conclude, that the intraoperative stress on the endothelium is equivalent with both systems used. PMID- 29452453 TI - [Personalized Ophthalmology - Induced Pluripotent Stem Cells for In Vitro Modelling of Retinal Degenerative Diseases]. AB - Today, the search for therapeutic options to treat retinal degeneration often relies on an in-depth understanding of the underlying pathological events. Alternatively, it is conceivable to search, in an undirected screening approach, for chemical compounds affecting disease outcome. For both approaches, there is an urgent need for in vitro and, ideally, in vivo disease models that adequately reflect the site of pathology. Currently available animal models possess limitations as they often develop only defined aspects of disease. Primary cell cultures, derived from the posterior pole of the eye, can only be obtained after invasive surgery or are available post mortem, but due to rapid cell senescence are not suited for long-term analysis. Immortalized retinal cell lines, on the other hand, differ in many aspects from native cells. In this situation, a promising alternative could arise from induced pluripotent stem cells (iPSCs). This cell species can be generated via non-invasive techniques, they are patient specific, can be propagated indefinitely, and theoretically can be differentiated in all types of retinal cells due to their pluripotent capacities. Importantly, the iPSC-derived retinal cells greatly resemble native cells in many characteristic traits. In this review we present a selection of established in vivo und in vitro models for retinal degenerative disease. We also discuss the potential of iPSCs for personalized in vitro modelling and provide an overview of existent iPSC-derived cell types of the posterior pole, particularly for cells of the retinal pigment epithelium. We finally give an outlook for the potential of such cells for basic research in ophthalmology. PMID- 29452454 TI - Macular Edema in Childhood Uveitis. AB - BACKGROUND: Pediatric uveitis is associated with a high incidence of severe and frequently permanent visual loss. This article summarizes the current understanding of the disease and the therapeutic options that are available to improve treatment outcomes. METHODS: A Medline search spanning the last 10 years was undertaken using the key terms "pediatric uveitis" or "childhood uveitis" and "macular edema". Articles which appertained to case reports or small case series were excluded from consideration, whereas those in which the opinions of experts were expressed, as well as reviews, were not. The information contained in these latter two forms of publication was particularly valuable, owing to the scarcity of prospective clinical data appertaining to the treatment of pediatric uveitis associated macular edema. RESULTS: Ten years ago, 34% of children who presented with uveitis manifested secondary complications at the time of diagnosis. During the ensuing 3 years of treatment, this rose to 86%. Heightening awareness of the disease with earlier referrals to expert centers, as well as the advent of therapeutic strategies involving anti-TNF agents and intravitreal corticosteroids, have led to a decrease in the incidence of legal blindness in the affected eyes from 18 - 69% to below 8% during a five-year course of treatment. CONCLUSION: Early diagnosis and strict control of inflammatory activity have led to a dramatic reduction in the incidence of vision-threatening secondary complications. In the majority of cases, it has also been possible to resolve cystoid macular edema, which, if insufficiently controlled by systemic therapy, usually responds well to intravitreal dexamethasone implants.

AB - Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal cancers with dismal patient outcomes. The underlying core genetic drivers of disease have been identified in human tumor specimens and described in genetically engineered mouse models. These genetic drivers of PDAC include KRAS signaling, TP53 mutations, and genetic loss of the SMAD4 tumor suppressor protein. Beyond the known mutational landscape of PDAC genomes, alternative disrupted targets that extend beyond conventional genetic mutations have been elusive and understudied in the context of PDAC cell therapeutic resistance and survival. This last point is important because PDAC tumors have a unique and complex tumor microenvironment that includes hypoxic and nutrient-deprived niches that could select for cell populations that garner therapeutic resistance, explaining tumor heterogeneity in regards to response to different therapies. We and others have embarked in a line of investigation focused on the key molecular mechanism of posttranscriptional gene regulation that is altered in PDAC cells and supports this pro-survival phenotype intrinsic to PDAC cells. Specifically, the key regulator of this mechanism is a RNA-binding protein, HuR (ELAVL1), first described in cancer nearly two decades ago. Herein, we will provide a brief overview of the work demonstrating the importance of this RNA-binding protein in PDAC biology and then provide insight into ongoing work developing therapeutic strategies aimed at targeting this molecule in PDAC cells.

PMID- 29452460 TI - Outcomes after surgical pulmonary embolectomy for acute submassive and massive pulmonary embolism: A single-center experience. AB - OBJECTIVES: Ideal treatment strategies for submassive and massive pulmonary embolism remain unclear. Recent reports of surgical pulmonary embolectomy have demonstrated improved outcomes, but surgical technique and postoperative outcomes continue to be refined. The aim of this study is to describe in-hospital survival and right ventricular function after surgical pulmonary embolectomy for submassive and massive pulmonary embolism with excessive predicted mortality (>=5%). METHODS: All patients undergoing surgical pulmonary embolectomy (2011 2015) were retrospectively reviewed. Patients with pulmonary embolism were stratified as submassive, massive without arrest, and massive with arrest. Submassive was defined as normotensive with right ventricular dysfunction. Massive was defined as prolonged hypotension due to the pulmonary embolism. Preoperative demographics, intraoperative variables, and postoperative outcomes were compared. RESULTS: A total of 55 patients were identified: 28 as submassive, 18 as massive without arrest, and 9 as massive with arrest. All patients had a right ventricle/left ventricle ratio greater than 1.0. Right ventricular dysfunction decreased from moderate preoperatively to none before discharge (P < .001). In-hospital and 1-year survival were 93% and 91%, respectively, with 100% survival in the submassive group. No patients developed renal failure requiring hemodialysis at discharge or had a postoperative stroke. CONCLUSIONS: In this single institution experience, surgical pulmonary embolectomy is a safe and effective therapy to treat patients with a submassive or massive pulmonary embolism. Although survival in this study is higher than previously reported for patients treated with medical therapy alone, a prospective trial comparing surgical therapy with medical therapy is necessary to further elucidate the role of surgical pulmonary embolectomy in the treatment of pulmonary embolism. PMID- 29452461 TI - Angiogenesis precedes cardiomyocyte migration in regenerating mammalian hearts. AB - OBJECTIVE: Although the mammalian heart's ability to fully regenerate is debated, its potential to extensively repair itself is gaining support. We hypothesized that heart regeneration relies on rapid angiogenesis to support myocardial regrowth and sought to characterize the timeline for angiogenesis and cell proliferation in regeneration. METHODS: One-day-old CD-1 mice (P1, N = 60) underwent apical resection or sham surgery. Hearts were explanted at serial time points from 0 to 30 days postresection and analyzed with immunohistochemistry to visualize vessel ingrowth and cardiomyocyte migration into the resected region. Proliferating cells were labeled with 5-ethynyl-2'-deoxyuridine injections 12 hours before explant. 5-Ethynyl-2'-deoxyuridine-positive cells were counted in both the apex and remote areas of the heart. Masson's trichrome was used to assess fibrosis. RESULTS: By 30 days postresection, hearts regenerated with minimal fibrosis. Compared with sham surgery, apical resection stimulated a significant increase in proliferation of preexisting cardiomyocytes between 3 and 11 days after injury. Capillary migration into the apical thrombus was detected as early as 2 days postresection, with development of mature arteries by 5 days postresection. New vessels became perfused by 5 days postresection as evidenced by lectin injection. Vessel density and diameter significantly increased within the resected area over 21 days, and vessel ingrowth always preceded cardiomyocyte migration, with coalignment of most migrating cardiomyocytes with ingrowing vessels. CONCLUSIONS: Endothelial cells migrate into the apical thrombus early after resection, develop into functional arteries, and precede cardiomyocyte ingrowth during mammalian heart regeneration. This endogenous neonatal response emphasizes the importance of expeditious angiogenesis required for neomyogenesis. PMID- 29452462 TI - Heart regeneration: The endothelial cell comes first.

PMID- 29452463 TI - Autosomal dominant mannose-binding lectin deficiency is associated with worse neurodevelopmental outcomes after cardiac surgery in infants. AB - OBJECTIVES: The MBL2 gene is the major genetic determinant of mannose-binding lectin (MBL)-an acute phase reactant. Low MBL levels have been associated with adverse outcomes in preterm infants. The MBL2Gly54Asp missense variant causes autosomal dominant MBL deficiency. We tested the hypothesis that MBL2Gly54Asp is associated with worse neurodevelopmental outcomes after cardiac surgery in neonates. METHODS: This is an analysis of a previously described cohort of patients with nonsyndromic congenital heart disease who underwent cardiac surgery with cardiopulmonary bypass before age 6 months (n = 295). Four-year neurodevelopment was assessed in 3 domains: Full-Scale Intellectual Quotient, the Visual Motor Integration development test, and the Child Behavior Checklist to assess behavior problems. The Child Behavior Checklist measured total behavior problems, pervasive developmental problems, and internalizing/externalizing problems. A multivariable linear regression model, adjusting for confounders, was fit. RESULTS: MBL2Gly54Asp was associated with a significantly increased covariate-adjusted pervasive developmental problem score (beta = 3.98; P = .0025). Sensitivity analyses of the interaction between age at first surgery and MBL genotype suggested effect modification for the patients with MBL2Gly54Asp (Pinteraction = .039), with the poorest neurodevelopment outcomes occurring in children who had surgery earlier in life. CONCLUSIONS: We report the novel finding that carriers of MBL2Gly54Asp causing autosomal dominant MBL deficiency have increased childhood pervasive developmental problems after cardiac surgery, independent of other covariates. Sensitivity analyses suggest that this effect may be larger in children who underwent surgery at earlier ages. These data support the role of nonsyndromic genetic variation in determining postsurgical neurodevelopment-related outcomes in children with congenital heart disease.

AB - BACKGROUND: The regional needs and consolidation of cardiac surgery services (CSS) result in an increased number of stand-alone interventional cardiology units. We aimed to explore the impact of a heart team on the decision making and outcomes of patients with multivessel coronary artery disease referred for coronary revascularization in stand-alone interventional cardiology units. METHODS: This prospective study included 1063 consecutive patients with multivessel disease enrolled between January and April 2013 from all 22 hospitals in Israel that perform coronary angiography and percutaneous coronary intervention (PCI), with or without on-site CSS. RESULTS: Of the 1063 patients, 487 (46%) underwent coronary artery bypass grafting (CABG) and 576 (54%) underwent PCI. A higher proportion of patients underwent PCI in hospitals without on-site CSS compared with those with on-site CSS (65% vs 46%; P < .001). Furthermore, patients referred to CABG from hospitals without on-site CSS had a significantly higher mean SYNTAX score compared with those who underwent CABG in centers with on-site CSS (29 vs 26; P = .018). Multivariate logistic regression analysis consistently showed that the absence of on-site cardiac surgery and a heart team was independently associated with a 2.5-fold increased likelihood for predicting the referral of PCI rather than CABG (odds ratio, 2.54; 95% confidence interval, 1.8-3.6). CONCLUSIONS: Patients with multivessel coronary artery disease treated in centers without on-site cardiac surgery services receive a lower rate of appropriate guideline-based intervention with CABG. These findings suggest that a heart team approach should be mandatory even in centers with stand alone interventional cardiology units.

AB - Aqueous proton transport involves the ultrafast interconversion of hydrated proton species that are closely linked to the hydrogen bond dynamics of water, which has been a long-standing challenge to experiments. In this study, we use ultrafast IR spectroscopy to investigate the distinct vibrational transition centered at 1750 cm-1 in strong acid solutions, which arises from bending vibrations of the hydrated proton complex. Broadband ultrafast two-dimensional IR spectroscopy and transient absorption are used to measure vibrational relaxation, spectral diffusion, and orientational relaxation dynamics. The hydrated proton bend displays fast vibrational relaxation and spectral diffusion timescales of 200-300 fs; however, the transient absorption anisotropy decays on a remarkably long 2.5 ps timescale, which matches the timescale for hydrogen bond reorganization in liquid water. These observations are indications that the bending vibration of the aqueous proton complex is relatively localized, with an orientation that is insensitive to fast hydrogen bonding fluctuations and dependent on collective structural relaxation of the liquid to reorient. We conclude that the orientational relaxation is a result of proton transfer between configurations that are well described by a Zundel-like proton shared between two flanking water molecules. PMID- 29452492 TI - Treatment patterns and Medicaid spending in comorbid schizophrenia populations: once-monthly paliperidone palmitate versus oral atypical antipsychotics. AB - OBJECTIVE: To compare treatment patterns and Medicaid spending between schizophrenia patients initiating once-monthly paliperidone palmitate (PP1M) and oral atypical antipsychotics (OAAs) within four comorbid populations: cardiovascular disease (CVD), diabetes, hypertension and obesity. METHODS: Five state Medicaid data identified comorbid adults with schizophrenia initiating PP1M or OAAs (index) from September 2009 balanced with inverse probability of treatment weighting. Chi-squared and t-tests compared index antipsychotic (AP) exposure (no gap >90 days) duration, AP polypharmacy, and index AP adherence (proportion of days covered >=80%) and persistence (no gap >=60 days) at 12 months post-index. Linear models with a non-parametric bootstrap procedure compared costs. RESULTS: PP1M patients consistently had longer index AP exposure (e.g. CVD: 244 vs. 189 days; p < .001) and less AP polypharmacy (e.g. CVD: 21.1% vs. 28.1%; p < .001) versus OAA patients. Relative to OAA patients, adherence was more likely in PP1M patients with CVD or obesity (e.g. CVD: 28.6% vs. 22.1%; p < .001) and less likely for patients with diabetes (22.0% vs. 24.4%; p = .031). Persistence was consistently more likely for PP1M versus OAA patients (e.g. CVD: 49.9% vs. 27.4%; p < .001). Total costs were not significantly different between PP1M and OAA patients for any comorbidity. PP1M patients with diabetes, hypertension or obesity had higher pharmacy and lower medical costs (all p < .05). CONCLUSIONS: Treatment with PP1M versus OAAs may reduce AP polypharmacy and increase AP persistence in comorbid patients with schizophrenia, without increasing total healthcare costs. Comorbidities are a highly prevalent driver of excess mortality in this vulnerable population; thus, future studies should specifically address the real-world effectiveness of therapies, including long acting injectable therapies (LAIs), for these patients. PMID- 29452493 TI - In vitro and in vivo evaluation of cyclodextrin-based nanosponges for enhancing oral bioavailability of atorvastatin calcium. AB - The aim of this study was to explore the feasibility of complexing the poorly water-soluble drug atorvastatin calcium (AC) with beta-cyclodextrin (beta-CD) based nanosponges (NS), which offer advantages of improving dissolution rate and eventually oral bioavailability. Blank NS were fabricated at first by reacting beta-CD with the cross-linker carbonyldiimidazole at different molar ratios (1:2, 1:4, and 1:8), then NS of highest solubilization extent for AC were complexed with AC. AC loaded NS (AC-NS) were characterized for various physicochemical properties. Pharmacokinetic, pharmacodynamics and histological finding of AC-NS were performed in rats. The prepared AC-NS showed particles size ranged from 408.7 +/- 12.9 to 423 +/- 15.9 nm while zeta potential values varied from -21.7 +/- 0.90 to -22.7 +/- 0.85 mV. The loading capacity varied from 17.9 +/- 1.21 to 34.1 +/- 1.16%. DSC, FT-IR, and PXRD studies confirmed the complexation of AC with NS and amorphous state of the drug in the complex. AC-NS displayed a biphasic release pattern with increase in the dissolution rate of AC as compared to plain AC. Oral administration of AC-NS (1:4 w/w, drug: NS) to rats led to 2.13 folds increase in the bioavailability as compared to AC suspension. Pharmacodynamics studies in rats with fatty liver revealed significant reduction (p < .05) in total cholesterol, triglyceride, LDL-C and increased level of beneficial HDL-C along with improvement in the associated liver steatosis as confirmed through photomicrographs of liver sections. In this study, we confirmed that complexation of AC with NS would be a viable approach for improving oral bioavailability and in vivo performance of AC.

PMID- 29452500 TI - Preparation of an optimized ciprofloxacin-loaded chitosan nanomicelle with enhanced antibacterial activity. AB - OBJECTIVE: The objective of this study was to evaluate the effect of lipid structure on physicochemical properties of chitosan-fatty acid nanomicelles and prepare an optimum ciprofloxacin-loaded formulation from these conjugates which could enhance the antibacterial effects of drug against some important pathogens like P. aeruginosa. SIGNIFICANCE: Nowadays, resistance in infectious diseases is a growing worldwide concern. Nanocarriers can increase the therapeutic index and consequently reduce the antibiotic resistance. By site-specific delivery of drug, the adverse effects of broad-spectrum antibiotics such as ciprofloxacin would be reduced. METHODS: Fatty acid grafted chitosan conjugates were synthetized in the presence of 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide. The effects of fatty acid type (stearic acid, palmitic acid, and linoleic acid) on physicochemical properties of conjugates were investigated. Ciprofloxacin was encapsulated in nanomicelles by thin film hydration method. Also, the preparation process was optimized with a central composite design. The antibacterial effect of optimum formulation against P. aeruginosa, K. pneumoniae, and S. pneumoniae species was determined. RESULTS: All conjugates were synthetized with high yield values and the substitution degrees ranged between 2.13 and 35.46%. Ciprofloxacin was successfully encapsulated in nanomicelles. The optimum formulation showed high drug loading (~ 19%), with particle size of about 260 nm and a sustained release profile of ciprofloxacin. The minimum inhibitory concentrations of ciprofloxacin in optimum formulation against P. aeruginosa and K. pneumoniae species were 4 and 2 times lower in comparison with the free drug, respectively. CONCLUSIONS: The antibacterial effect of ciprofloxacin was improved by encapsulation of drug in chitosan nanomicelles.

AB - BACKGROUND: An increasing number of reports indicates that vaccines against influenza may interact with specific drugs via drug metabolism. To date, actual impact of vaccine-drug interactions observed in the real world clinical practice has not been investigated. METHODS: From VAERS and VigiBase, we collected Adverse Event Following Immunization (AEFI) reports for individuals receiving vaccines against influenza recorded as suspect and selected cases where predictable toxicity was recorded with oral anticoagulants, antiepileptics and statins (i.e. hemorrhages, overdosage and rhabdomyolysis, respectively). We applied AEFI and Drug Interaction Probability Scale (DIPS) Algorithms to assess causality of drug vaccine interactions. RESULTS: 116 AEFI reports submitted to VAERS and 83 from Vigibase were included in our analysis; antiepileptics and statins were related to the highest number of indeterminate/consistent (93.7%; 65.3%) and possible/probable (50%; 57.7%) cases according to the AEFI and DIPS, respectively. The majority of cases occurred within the first week after vaccine administration (5-7 days). CONCLUSION: The relative paucity of detected interactions does not impact on the benefit of the vaccination against influenza, which remains strongly recommended; this does not exclude that closer monitoring for selected patients exposed to concomitant chronic pharmacological therapies and affected by predisposing factors may be useful.

AB - This article evaluates the anticancer drug delivery performances of two nanohydrogels composed of poly(N-isopropylacrylamide-co-itaconic anhydride) [P(NIPAAm-co-IA)], poly(ethylene glycol) (PEG), and Fe3O4 nanoparticles. For this purpose, the magnetite nanohydrogels (MNHGs) were loaded with doxorubicin hydrochloride (DOX) as a universal anticancer drug. The morphologies and magnetic properties of the DOX-loaded MNHGs were investigated using transmission electron microscopy (TEM) and vibrating-sample magnetometer (VSM), respectively. The sizes and zeta potentials (xi) of the MNHGs and their corresponding DOX-loaded nanosystems were also investigated. The DOX-loaded MNHGs showed the highest drug release values at condition of 41 degrees C and pH 5.3. The drug-loaded MNHGs at physiological condition (pH 7.4 and 37 degrees C) exhibited negligible drug release values. In vitro cytotoxic effects of the DOX-loaded MNHGs were extensively evaluated through the assessing survival rate of HeLa cells using the MTT assay, and there in vitro cellular uptake into the mentioned cell line were examined using fluorescent microscopy and fluorescence-activated cell sorting (FACS) flow cytometry analyses. As the results, the DOX-loaded MNHG1 exhibited higher anticancer drug delivery performance in the terms of cytotoxic effect and in vitro cellular uptake. Thus, the developed MNHG1 can be considered as a promising de novo drug delivery system, in part due to its pH and thermal responsive drug release behavior as well as proper magnetite character toward targeted drug delivery.

AB - INTRODUCTION: CA125 has poor sensitivity and low specificity for detecting early ovarian cancer. Serum ferritin is elevated in many malignancies. We evaluated the performance of ferritin alone and in combination with CA125 as a diagnostic tool to detect epithelial ovarian cancer (EOC). METHODS: CA125 and ferritin were detected in the serum of 50 healthy control (HC), 50 women with benign gynaecological conditions and 124 women with EOC. The relationship between serum ferritin and CA125 and each of the clinicopathological parameters was assessed, and their diagnostic accuracy for discriminating ovarian cancer determined. RESULTS: Serum ferritin and CA125 were higher in patients with EOC compared to HCs and patients with benign conditions (both p < 0.001). There was no relationship between levels of ferritin and CA125. Both ferritin and CA125 discriminated HC from EOC (p < 0.05), but ferritin showed better diagnostic accuracy than CA125 (p = 0.048). Ferritin was superior to CA125 in discrimination early EOC (p = 0.002), but in advanced stages, CA125 was superior (p = 0.026). A combination of ferritin and CA125 marginally increases the diagnostic accuracy to discriminate EOC from HCs. CONCLUSION: Ferritin discriminates between HCs and EOC patients, especially in early stage disease. The combination of serum ferritin and CA125 provides the higher diagnostic accuracy to screen for EOC. Serum ferritin could serve as an EOC biomarker to complement the standard CA125 test.

AB - Dry eye syndrome (DES) is considered as an ocular surface inflammatory disease. Previous studies have shown inflammation plays an important role in the progression and onset of DES. Co-culture of human bone marrow mesenchymal stem cells (HBMSCs) and macrophages showed immunomodulatory effects via regulation of cytokine regulation. Thus, the aim of this study was to investigate the effect of the interaction of these cells on in vitro DES model. The conditioned media (CM) from macrophages, HBMSCs, and HBMSCs + macrophages were treated to human corneal epithelial cells, which showed significant reduction in IL-1alpha and IL-1beta expression levels in HBMSCs + macrophages group. Moreover, the IL-1 Receptor Antagonist (IL-1RA) was highly expressed in the CM from the HBMSCs + macrophages group. Wounded eyes of mice were treated with IL-1RA at 0-100 ng/mL for 16 h, the wound size was reduced. The results of this study might lead to the identification of new therapeutic targets for DES.

PMID- 29452544 TI - Can combined blood neutrophil to lymphocyte ratio and C-reactive protein be used for diagnosis of spontaneous bacterial peritonitis? AB - BACKGROUND AND OBJECTIVE: Spontaneous bacterial peritonitis (SBP) is diagnosed by the presence of >=250 polymorphonuclear neutrophils (PMN)/mm3 in the ascites and the absence of surgically treatable cause of intra-abdominal infection. Blood neutrophil lymphocytic ratio (NLR) is an inexpensive and simple test for inflammation. C-reactive protein (CRP) is an inflammatory marker used for the diagnosis and follow-up of many diseases and morbidities. We aimed to evaluate the clinical utility of combined blood NLR and CRP as a non-invasive test for SBP diagnosis. METHODS: Blood NLR was calculated, and CRP value determined in 180 cirrhotic patients with ascites (126 with and 54 without SBP). Sensitivity and specificity of combined blood NLR and CRP values for SBP diagnosis were estimated by receiver operator characteristic curve. RESULTS: Both blood NLR and CRP values were significantly higher in SBP (p < 0.001). For SBP diagnosis, a blood NLR of >2.89 had a sensitivity 80.3% and specificity 88.9%. CRP >11.3 mg/dL had a sensitivity 88.9% and specificity 92.6%. In logistic regression analysis, combined blood NLR and CRP had a sensitivity 95.1% and specificity 96.3% at the same cut off values. CONCLUSIONS: Combined NLR and CRP could be used as a novel, simple, low-cost, non-invasive test for SBP diagnosis.

AB - BACKGROUND: Macrovascular complications are the main cause of morbidity and mortality among the diabetic patients. MicroRNAs (miRNAs), a family of small non coding RNAs, play vital roles in the regulation of blood glucose level and the concurrent cardiovascular complications of type 2 diabetes. We hypothesized that plasma miR-126 and miR-210 are linked to coronary artery disease (CAD) in these diabetes patients. METHODS: Fasting blood samples were collected from 20 healthy volunteers and 100 patients with diabetes (54 patients without CAD and 46 patients with CAD). Plasma miR-126 and miR-210 expressions were assessed by quantitative real time PCR. Specificity and sensitivity of miR-126 and miR-210 to discriminate CAD with diabetes was determined by receiver operating characteristic curve analysis. Correlations between miR-126 and miR-210 and studied characteristics in diabetes patients with and without CAD were compared. RESULTS: Plasma relative expressions of miR-126 and miR-210 were 0.38 +/- 0.03 and 5.3 +/- 0.56 in diabetes alone vs. 0.08 +/- 0.03 and 21.44 +/- 0.97 in diabetes with CAD, respectively (both p < 0.0001). Levels of miR-126 and miR-210 significantly correlated with certain glycemic and lipid indices. The miRNAs significantly discriminated between diabetes with and without CAD at cut-off values of 0.055 (sensitivity 91.3%, specificity 100%) for miR-126 and of 17.59 (sensitivity 93.5%, specificity 100%) for miR-210. CONCLUSION: Plasma miR-126 and miR-210 levels may be biomarkers for diabetes with or without CAD. PMID- 29452549 TI - Characterizing Potentially Preventable Cancer- and Chronic Disease-Related Emergency Department Use in the Year After Treatment Initiation: A Regional Study. AB - PURPOSE: As new quality metrics and interventions for potentially preventable emergency department (ED) visits are implemented, we sought to compare methods for evaluating the prevalence and costs of potentially preventable ED visits that were related to cancer and chronic disease among a commercially insured oncology population in the year after treatment initiation. METHODS: We linked SEER records in western Washington from 2011 to 2016 with claims from two commercial insurers. The study included patients who were diagnosed with a solid tumor and tracked ED utilization for 1 year after the start of chemotherapy or radiation. Cancer symptoms from the Centers for Medicare & Medicaid Services metric and a patient-reported outcome intervention were labeled potentially preventable (PpCancer). Prevention Quality Indicators of the Agency for Healthcare Research and Quality were labeled potentially preventable-chronic disease (PpChronic). We reported the primary diagnosis, all diagnosis field coding (1 to 10), and 2016 adjusted reimbursements. RESULTS: Of 5,853 eligible patients, 27% had at least one ED visit, which yielded 2,400 total visits. Using primary diagnosis coding, 49.8% of ED visits had a PpCancer diagnosis, whereas 3.2% had a PpChronic diagnosis. Considering all diagnosis fields, 45.0%, 9.4%, and 18.5% included a PpCancer only, a PpChronic only, and both a PpCancer and a PpChronic diagnosis, respectively. The median reimbursement per visit was $735 (interquartile ratio, $194 to $1,549). CONCLUSION: The prevalence of potentially preventable ED visits was generally high, but varied depending on the diagnosis code fields and the group of codes considered. Future research is needed to understand the complex landscape of potentially preventable ED visits and measures to improve value in cancer care delivery.

PMID- 29452556 TI - Use of a Prescription-Assistance Program for Medically Uninsured Patients With Cancer: Case Study of a Public Hospital Experience in New York State. AB - PURPOSE: With the advances in early detection, prevention, and treatment of some cancers, mortality rates in the United States have been consistently falling. However, with these successes have come substantial increases in the cost of cancer care. Antineoplastics are the leading class in hospital drug expenditures. Cancer treatments are causing a serious financial burden for patients, families, hospitals, and society at large, especially for those who are uninsured. Prescription assistance programs (PAPs) are offered by pharmaceutical manufacturers to provide medications at no out-of-pocket cost to medically indigent patients. To assist the Cancer Care Center at Nassau University Medical Center (NUMC) with drug costs for chemotherapies, a clinical pharmacist-managed PAP was implemented to procure chemotherapy medications from pharmaceutical manufacturers. NUMC is a safety-net teaching hospital in suburban New York. It serves mostly an indigent population, and its Level I trauma center has more than 77,000 emergency department visits per year. METHODS: We observed all patients requiring assistance with chemotherapy who enrolled in PAPs from January 1, 2011, through December 31, 2012. The total number of visits in the clinic over 24 months was 9,405. Individuals potentially eligible for the PAP were identified by oncologists. Patients received a referral to the PAP when they mentioned to office personnel that they had difficulty obtaining medications or expressed financial concerns related to management. RESULTS: The clinical pharmacist spent the majority of his time assisting uninsured individuals, working with charity pools from the drug manufacturers, and obtaining medications through the PAP. The program served 341 patients in 2011 and 579 patients in 2012. Medications obtained for these patients included both oral and parenteral chemotherapy drugs and antiemetics. The total cost savings of the medications was $908,944.11 in 2011 and $1,715,538.37 in 2012. In 2012, a total of 783 prescriptions were processed, and 775 were approved by the manufacturers (98.9%). CONCLUSION: PAPs provide a valuable safety net to ensure that uninsured patients with cancer receive needed prescription medications. The rising cost of health care and the high proportion of indigent patients have financially burdened the hospital. For the pharmacy department, this has resulted in a lack of compensation for pharmaceuticals dispensed to indigent patients. A pharmacy-based program to procure free medications for uninsured patients with cancer has helped to defray the expenses of the Cancer Care Center in providing care at NUMC, increased patient compliance with chemotherapy protocols, and allowed many patients to receive the treatments they otherwise would not have been able to afford. PMID- 29452557 TI - Michigan Oncology Medical Home Demonstration Project: First-Year Results. AB - PURPOSE: The Michigan Oncology Medical Home Demonstration Project (MOMHDP) is an innovative multipractice oncology medical home model, supported by payment reform. Sponsored by Priority Health, Physician Resource Management, and ION Solutions, MOMHDP includes four oncology practices and 29 physicians. METHODS: Oncology practices used existing technologies, with MOMHDP providing evidence based treatment guideline selection and compliance tracking, automated physician order entry, a patient portal, symptom management/standardized nurse triage, and advance care planning. To support changes in care and administrative models and to focus on quality, MOMHDP modifies provider payments. The program replaces the average sales price payment methodology with a drug acquisition reimbursement plus a care management fee, calculated to increase total drug reimbursement. Additionally, it reimburses for chemotherapy and treatment planning and advance care planning consultation. There is also a shared savings opportunity. MOMHDP will be enhanced in its second year to include a survivorship program, patient distress screening, imaging guidelines, and standardized patient satisfaction surveys. Priority Health patients receiving chemotherapy for a cancer diagnosis were recruited to the program. Results for this group were compared with a control group of patients from a prior period. RESULTS: In addition to the financial results, the project also accomplished the following: (1) adherence to practice-selected guidelines, (2) institution of advance care planning, (3) effective and standardized symptom management; and (4) payment reform. CONCLUSION: We have identified a number of critical success factors: strong payer/provider collaboration built on trust through transparent use and cost data; timing of clinical standardization must come from the practices, so they can effectively absorb new approaches; having comprehensive, written program documentation and consistently applied training facilitate practice understanding; existing, off-the-shelf technologies help control costs; independent clinical, administrative, and technical coordination improves provider/payer collaboration; everything takes longer than anticipated, including practice commitment, contracting, and technology implementation. Practices are willing to take on clinical standardization with payment reform. Neither practice size nor technology platform variation was a barrier to participation or success in the project. These results represent preliminary reporting from the first multipractice oncology medical home in the United States, to our knowledge, with payer support that includes payment reform. The results are promising, and the concept warrants further study, review, and reporting. [Table: see text]. PMID- 29452558 TI - Achieving the Meaningful Use Standard: A Model for Implementing Change Within Medical Practices. AB - PURPOSE: Change management in medical practices is often an uphill battle. Lack of agreement on standards, ineffective leadership, inertia, inconsistent access to data, and inability to clearly define and communicate the benefits of change represent significant barriers to success. In 2009, the Health Information Technology for Economic and Clinical Health (HITECH) Act created the meaningful use (MU) incentive program administered through the Centers for Medicare and Medicaid Services (CMS). To earn financial incentive payments, eligible physicians adopt certified electronic health record (EHR) technology and use it to meet specified objectives. In response, leadership of the US Oncology Network launched an MU initiative designed to create a comprehensive system of tools, education, performance feedback, and support that would facilitate successful achievement of the MU standards. METHODS: The EHR used by the majority of network physicians was modified according to the MU specifications, and EHR certification was obtained. Baseline compliance data were measured for each of the MU standards and for each of the eligible physicians. Physician and staff workflow processes necessary for consistent data input and compliance were outlined for each standard. Each practice identified one or more staff members who would act as MU leads. Training modules were developed for the MU leads as well as for physicians, mid-level providers, nurses, medical assistants, and office staff. An MU measurement tool was created, designed to target areas for MU process improvement and automate reporting. Data were updated and verified weekly to provide timely feedback to practices, including individual physician detail and links to individual patient records. RESULTS: A total of 943 practitioners within the US Oncology Network met eligibility criteria for the MU program. At baseline, compliance with each MU standard ranged from 0% (clinical summaries) to 100% (computerized order entry). In many cases, data were simply not being entered into the EHR. Time from program launch to first submission of MU attestation was 18 months. As of March 2013, 781 practitioners (83%) had achieved the MU standards. In comparison, CMS reported that 44% of all eligible physicians and 26% of hematologists and oncologists had successfully achieved Medicare MU standards and received payment. CONCLUSION: Successful change management in medical practices can be accomplished through a comprehensive system of leadership, education, support, timely feedback of data, and clearly defined incentives. Incentives alone may be far less effective. PMID- 29452559 TI - Improving Medical Oncology Quality Through Peer-to-Peer Consultation. AB - PURPOSE: This study describes how the use of peer-to-peer (P2P) physician consultation improves medical oncology care quality by preventing non-evidence based and potentially morbid chemotherapy treatments. New Century Health (NCH) has adapted a physician audit and feedback model to strengthen adherence to clinical guidelines. In the NCH oncology program, P2P consultation complements clinical pathways and an online prior authorization platform. Payers are adopting the use of clinical pathways as a management strategy for managing costs and improving quality. Managing medical oncology is a complex process, because evidence evolves rapidly, and almost one third of chemotherapy is prescribed off label. The use of prior authorization, combined with standardized protocols for patients with specific cancer diagnoses, is one way for payers to reduce unnecessary treatment variation. [Table: see text] Methods: NCH completed a retrospective analysis of the chemotherapy treatment requests (CTRs) submitted by payers' oncologists for prior authorization between January and December 2012. The objectives of the clinical impact analysis were to measure the CTR disposition rate, identify the CTR intervention rate resulting from P2P consultation, and identify the types of drug triggering the interventions. RESULTS: Analysis of the 13,078 CTRs associated with the 1,116 unique Medicare and commercial patients of a national health plan determined that CTRs voluntarily withdrawn or recommended adverse determination (RAD; ie, NCH recommendation to member's health plan to not authorize treatment as requested; after review of health plan policy and compendia, NCH was not able to resolve provider's request through P2P consultation and could not recommend approval of treatment plan as requested, therefore recommending denial of request) by the submitting physician as a result of a P2P consultation with an NCH board certified oncologist comprised 11.6% of all CTRs. Further analysis identified the types of medication associated with the 1,521 CTRs withdrawn/RAD as a consequence of P2P consultation. Interventions on chemotherapeutic medications and supportive care were evenly distributed at 51.2% and 48.8%, respectively. Interventions on medications that had received US Food and Drug Administration approval within the last 2 years (initial approval or for new indications) represented 12.1%. [Table: see text] Conclusion: Using P2P consultation to complement a pathway-driven prior authorization process improves medical oncology quality. In addition, P2P consultation can be an effective collaborative physician engagement strategy by supporting oncologists with critical clinical information and mitigating concerns about pathway implementation and about payer involvement in drug use management. PMID- 29452560 TI - Health Care Efficiencies: Consolidation and Alternative Models vs. Health Care and Antitrust Regulation - Irreconcilable Differences? AB - Despite the U.S. substantially outspending peer high income nations with almost 18% of GDP dedicated to health care, on any number of statistical measurements from life expectancy to birth rates to chronic disease, 1 the U.S. achieves inferior health outcomes. In short, Americans receive a very disappointing return on investment on their health care dollars, causing economic and social strain. 2 Accordingly, the debates rage on: what is the top driver of health care spending? Among the culprits: poor communication and coordination among disparate providers, paperwork required by payors and regulations, well-intentioned physicians overprescribing treatments, drugs and devices, outright fraud and abuse, and medical malpractice litigation. Fundamentally, what is the best way to reduce U.S. health care spending, while improving the patient experience of care in terms of quality and satisfaction, and driving better patient health outcomes? Mergers, partnerships, and consolidation in the health care industry, new care delivery models like Accountable Care Organizations and integrated care systems, bundled payments, information technology, innovation through new drugs and new medical devices, or some combination of the foregoing? More importantly, recent ambitious reform efforts fall short of a cohesive approach, leaving fundamental internal inconsistencies across divergent arms of the federal government, raising the issue of whether the U.S. health care system can drive sufficient efficiencies within the current health care and antitrust regulatory environments. While debate rages on Capitol Hill over "repeal and replace," only limited attention has been directed toward reforming the current "fee-for service" model pursuant to which providers are paid for volume of care rather than quality or outcomes. Indeed, both the Patient Protection and Affordable Care Act ("ACA") 3 and proposals for its replacement focus primarily on the reach and cost of providing coverage for health care, rather than specifics for the delivery of health care. 4 With the U.S. expenditures on health care producing inferior results, experts see consolidation and alternatives to fee-for-service as fundamental to reducing costs. 5 Integrating care coordination and delivery and increasing scale to drive efficiencies allows organizations to benefit from shared savings and relationships with payors and vendors. 6 Deloitte forecasts that, by 2024, the current health system landscape-which includes roughly 80 national health systems, 275 regional systems, 130 academic medical centers, and 1,300 small community systems-will morph into just over 900 multi-hospital systems. 7 Even though health care market and payment reforms encourage organizations to consolidate and integrate, innovators must proceed with extreme caution. Health care organizations attempting to drive efficiencies and bring down costs through mergers may run afoul of numerous federal and state laws and regulations. 8 Calls for updates or leniency in these laws are growing, including the possible recognition of an "Obamacare defense" to antitrust restrictions 9 and speculation that laws restricting physicians from having financial relationships will be repealed, ostensibly to allow sharing of the rewards reaped from coordinated care. 10 In the meantime, however, absent specific waivers or exemptions, all the usual rules and regulations apply, including antitrust constraints, 11 physician self-referral 12 and anti-kickback laws and regulations, 13 state fraud and abuse restrictions, 14 and more. In short, a maelstrom of conflicting political prescriptions, health care regulations, and antitrust restrictions undermine the ability of innovators to achieve efficiencies through joint ventures, transactions, innovative models, and other structures. This article first considers the conflicting positions taken by the United States government with respect to achieving efficiencies in health care under the ACA and alternative delivery models, on the one hand, and health care regulatory enforcement and antitrust enforcement, on the other. At almost a fifth of the U.S. economy, 15 health care arguably has grown ungovernable, exceeding the ability of any one law or branch of government to create or implement coherent reform. Indeed, the article posits that although the ACA reformed and expanded access to health care, it failed to transform the way health care is delivered beyond limited "demonstration projects", leaving fee-for-service intact. Nonetheless, even with limited rather than revolutionary goals, the ACA still lacks sufficient authority across disparate branches of government to achieve its stated goals. The article then examines the conflicting positions of the various United States regulatory schemes and enforcement agencies governing health care, and whether they can be reconciled with the stated goal of the government, often referred to as the "Triple Aim": 16 improving quality of care, improving population health, and lowering health care costs. It examines fundamental, systemic challenges to achieving the "Triple Aim": longstanding health care regulatory laws that impede adoption of innovative delivery systems beyond their current "demonstration project" status, and antitrust enforcement that promotes waste and duplication in densely populated areas, while preventing necessary consolidation to more efficiently reach rural areas. The article concludes with recommendations for promoting efficiency through modest reconciliation of the conflicting goals and regulations in health care.

AB - The Physician Payments Sunshine Act ("Sunshine Act"), enacted to address financial conflicts in health care, is the first comprehensive federal legislation mandating public reporting of payments between drug companies, device manufacturers, and medicine. This article analyzes the Sunshine Act's uneven record, exploring how the law serves as an intriguing example of the uncertain case for transparency regulation in health care. The Sunshine Act's bumpy rollout demonstrates that commanding transparency through legislation can be arduous because of considerable implementation challenges. Capturing all the relevant information about financial relationships and reporting it with sufficient contextual and comparative data has proven disappointingly difficult. In addition, the law suffers from uncertainty and poor design as to the intended audience. Indeed, there is strong reason to believe that it will not significantly impact decision-making of primary recipients like patients. Yet the Sunshine Act nonetheless retains important and perhaps underappreciated value. From the almost four years of information generated, we have learned that industry-medicine financial ties vary significantly by physician specialty, and somewhat by physician gender. In many medical fields the distribution of top dollar payments tends to be heavily skewed to a few recipients, all of which have important implications for optimal management of financial conflicts and for health policy more generally. Accordingly, the Sunshine Act's greatest potential is not guiding decisions of individual patients or physicians, but its downstream effects. This Article traces how secondary audiences, such as regulators, watchdogs, and counsel are already starting to make productive use of Sunshine Act information. Public reporting has, for example, made more feasible linking industry payment information with Medicare reimbursement data. As a result, policymakers can more closely examine correlations between industry spending directed at individual physicians and their prescribing and referral decisions. Moreover, savvy counsel are recognizing that Sunshine Act information provides explosive evidence in private civil litigation and this Article explores the first wave of cases. PMID- 29452563 TI - Code Red: The Essential Yet Neglected Role of Emergency Care in Health Law Reform. AB - The United States' health care system is mired in uncertainty. Public opinion on the Patient Protection and Affordable Care Act ("ACA") is undeniably mixed and politicized. The individual mandate, tax subsidies, and Medicaid expansion dominate the discussion. This Article argues that the ACA and reform discourse have given short shrift to a more static problem: the law of emergency care. The Emergency Medical Treatment and Active Labor Act of 1986 ("EMTALA") requires most hospitals to screen patients for emergency medical conditions and provide stabilizing treatment regardless of patients' insurance status or ability to pay. Remarkably, this law strengthened the health safety net in a country that has no universal health care. But it is an unfunded mandate that responded to the problem of emergency care in a flawed fashion and contributed to the supposed "free rider" problem that the ACA attempted to cure. But the ACA has also not been effective at addressing the issue of emergency care. The ACA's architects reduced funding for hospitals that serve a disproportionate percentage of the medically indigent but did not anticipate the Supreme Court's ruling in NFIB v. Sebelius, which made Medicaid expansion optional. Public and non-profit hospitals now face a scenario of less funding and potentially higher emergency room utilization due to continued uninsurance or underinsurance. Alternatives to the ACA have been insufficiently attentive to the importance of emergency care in our health system. This Article contends that any proposal that does not seriously consider EMTALA is incomplete and bound to produce some of the same problems that have dogged the American health care system for the past few decades. Moreover, the Article shows how notions of race, citizenship, and deservingness have filtered into this health care trajectory, and in the context of reform, have the potential to exacerbate existing health inequality. The paper concludes with normative suggestions on how to the mitigate EMTALA's problems in ways that might improve population health. PMID- 29452564 TI - When Consent Does Not Help: Challenges to Women's Access to a Vaginal Birth After Cesarean Section and the Limitations of the Informed Consent Doctrine. AB - Pregnant women with a prior cesarean delivery face challenges in accessing a vaginal birth due to both hospital and provider preferences and practices. Although the doctrine of informed consent secures women's reproductive rights, it is not a viable legal remedy. Instead, women should champion increased maternity related education and transparency as well as medical malpractice reform to increase the desired access. PMID- 29452565 TI - Serum vitamin C levels modulate the lifespan and endoplasmic reticulum stress response pathways in mice synthesizing a nonfunctional mutant WRN protein. AB - Werner syndrome (WS) is a premature aging disorder caused by mutations in a RecQ family DNA helicase (WRN). Mice lacking part of the helicase domain of the WRN ortholog exhibit several phenotypic features of WS. In this study, we generated a Wrn mutant line that, like humans, relies entirely on dietary sources of vitamin C (ascorbate) to survive, by crossing them to mice that lack the gulonolactone oxidase enzyme required for ascorbate synthesis. In the presence of 0.01% ascorbate (w/v) in drinking water, double-mutant mice exhibited a severe reduction in lifespan, small size, sterility, osteopenia, and metabolic profiles different from wild-type (WT) mice. Although increasing the dose of ascorbate to 0.4% improved dramatically the phenotypes of double-mutant mice, the metabolic and cytokine profiles were different from age-matched WT mice. Finally, double mutant mice treated with 0.01% ascorbate revealed a permanent activation of all the 3 branches of the ER stress response pathways due to a severe chronic oxidative stress in the ER compartment. In addition, markers associated with the ubiquitin-proteasome-dependent ER-associated degradation pathway were increased. Augmenting the dose of ascorbate reversed the activation of this pathway to WT levels rendering this pathway a potential therapeutic target in WS.-Aumailley, L., Dubois, M. J., Brennan, T. A., Garand, C., Paquet, E. R., Pignolo, R. J., Marette, A., Lebel, M.

PMID- 29452567 TI - A critical role for both CD40 and VLA5 in angiotensin II-mediated thrombosis and inflammation. AB - Angiotensin II (Ang-II)-induced hypertension is associated with accelerated thrombus formation in arterioles and leukocyte recruitment in venules. The mechanisms that underlie the prothrombotic and proinflammatory responses to chronic Ang-II administration remain poorly understood. We evaluated the role of CD40/CD40 ligand (CD40L) signaling in Ang-II-mediated microvascular responses and assessed whether and how soluble CD40L (sCD40L) contributes to this response. Intravital video microscopy was performed to analyze leukocyte recruitment and dihydrorhodamine-123 oxidation in postcapillary venules. Thrombus formation in cremaster muscle arterioles was induced by using the light/dye endothelial cell injury model. Wild-type (WT), CD40-/-, and CD40L-/- mice received Ang-II for 14 d via osmotic minipumps. Some mice were treated with either recombinant sCD40L or the VLA5 (very late antigen 5; alpha5beta1) antagonist, ATN-161. Our results demonstrate that CD40-/-, CD40L-/-, and WT mice that were treated with ATN-161 were protected against the thrombotic and inflammatory effects of Ang-II infusion. Infusion of sCD40L into CD40-/- or CD40L-/- mice restored the prothrombotic effect of Ang-II infusion. Mice that were treated with ATN-161 and infused with sCD40L were protected against accelerated thrombosis. Collectively, these novel findings suggest that the mechanisms that underlie Ang-II-dependent thrombotic and inflammatory responses link to the signaling of CD40L via both CD40 and VLA5.-Senchenkova, E.

PMID- 29452566 TI - Near-tetraploid cancer cells show chromosome instability triggered by replication stress and exhibit enhanced invasiveness. AB - A considerable proportion of tumors exhibit aneuploid karyotypes, likely resulting from the progressive loss of chromosomes after whole-genome duplication. Here, by using isogenic diploid and near-tetraploid (4N) single-cell derived clones from the same parental cell lines, we aimed at exploring how polyploidization affects cellular functions and how tetraploidy generates chromosome instability. Gene expression profiling in 4N clones revealed a significant enrichment of transcripts involved in cell cycle and DNA replication. Increased levels of replication stress in 4N cells resulted in DNA damage, impaired proliferation caused by a cell cycle delay during S phase, and higher sensitivity to S phase checkpoint inhibitors. In fact, increased levels of replication stress were also observed in nontransformed, proliferative posttetraploid RPE1 cells. Additionally, replication stress promoted higher levels of intercellular genomic heterogeneity and ongoing genomic instability, which could be explained by high rates of mitotic defects, and was alleviated by the supplementation of exogenous nucleosides. Finally, our data found that 4N cancer cells displayed increased migratory and invasive capacity, both in vitro and in primary colorectal tumors, indicating that tetraploidy can promote aggressive cancer cell behavior.-Wangsa, D., Quintanilla, I., Torabi, K., Vila Casadesus, M., Ercilla, A., Klus, G., Yuce, Z., Galofre, C., Cuatrecasas, M., Lozano, J.

PMID- 29452568 TI - Primary cilia-regulated transcriptome in the renal collecting duct. AB - Renal tubular cells respond to mechanical stimuli generated by urinary flow to regulate the activity and transcript abundance of important genes for ion handling, cellular homeostasis, and proper renal development. The primary cilium, a mechanosensory organelle, is postulated to regulate this mRNA response. The aim of this study is to reveal the transcriptome changes of tubular epithelia in response to fluid flow and determine the role of primary cilia in this process. Inner-medullary collecting duct (CD) cells were subjected to either static or physiologically relevant fluid flow (~0.6 dyn/cm2). RNA-sequencing analysis of ciliated cells subjected to fluid flow showed up-regulation of 1379 genes and down-regulation of 1294 genes compared with static control cells. Strikingly, only 54 of these genes were identified as gene candidates sensitive to primary cilia sensing of fluid flow, of which 16 were linked to ion or water transport pathways in the CD. Validation by quantitative real-time PCR revealed that only the expression of transferrin receptor, which is involved in iron transport; and tribbles pseudokinase 3, which is involved in insulin signaling, were unequivocally regulated by primary cilia sensing of fluid flow. This study shows that the involvement of primary cilia in ion transport in the collecting duct is exceptionally specific.-Mohammed, S. G., Arjona, F. J., Verschuren, E. H. J., Bakey, Z., Alkema, W., van Hijum, S., Schmidts, M., Bindels, R. J. M., Hoenderop, J. G. J. Primary cilia-regulated transcriptome in the renal collecting duct. PMID- 29452570 TI - S1P transporter SPNS2 regulates proper postnatal retinal morphogenesis. AB - Spinster homolog 2 (SPNS2) is the membrane transporter of sphingosine-1-phosphate (S1P), and it participates in several physiologic processes by activating different S1P receptors (S1PRs). However, its functions in the nervous system remain largely unclear. We explored the important role of SPNS2 in the process of retinal morphogenesis using a spns2-deficient rat model. In the absence of the functional SPNS2 transporter, we observed progressively aggravating laminar disorganization of the epithelium at the postnatal stage of retinal development. Disrupted cell polarity, delayed cell-cycle exit of retinal progenitor cells, and insufficient migration of newborn neurons were proposed in this study as potential mechanisms accounting for this structural disorder. In addition, we analyzed the expression profiles of spns2 and s1prs, and proposed that SPNS2 regulated retinal morphogenesis by establishing the S1P level in the eye and activating S1PR3 signaling. These data indicate that SPNS2 is indispensable for normal retinal morphogenesis and provide new insights on the role of S1P in the developing retina using an established in vivo model.-Fang, C., Bian, G., Ren, P., Xiang, J., Song, J., Yu, C., Zhang, Q., Liu, L., Chen, K., Liu, F., Zhang, K., Wu, C., Sun, R., Hu, D., Ju, G., Wang, J.

PMID- 29452569 TI - Up-regulation of SFTPB expression and attenuation of acute lung injury by pulmonary epithelial cell-specific NAMPT knockdown. AB - Although a deficiency of surfactant protein B (SFTPB) has been associated with lung injury, SFTPB expression has not yet been linked with nicotinamide phosphoribosyltransferase (NAMPT), a potential biomarker of acute lung injury (ALI). The effects of Nampt in the pulmonary epithelial cell on both SFTPB expression and lung inflammation were investigated in a LPS-induced ALI mouse model. Pulmonary epithelial cell-specific knockdown of Nampt gene expression, achieved by the crossing of Nampt gene exon 2 floxed mice with mice expressing epithelial-specific transgene Cre or by the use of epithelial-specific expression of anti-Nampt antibody cDNA, significantly attenuated LPS-induced ALI. Knockdown of Nampt expression was accompanied by lower levels of bronchoalveolar lavage (BAL) neutrophil infiltrates, total protein and TNF-alpha levels, as well as lower lung injury scores. Notably, Nampt knockdown was also associated with significantly increased BAL SFTPB levels relative to the wild-type control mice. Down-regulation of NAMPT increased the expression of SFTPB and rescued TNF-alpha induced inhibition of SFTPB, whereas overexpression of NAMPT inhibited SFTPB expression in both H441 and A549 cells. Inhibition of NAMPT up-regulated SFTPB expression by enhancing histone acetylation to increase its transcription. Additional data indicated that these effects were mainly mediated by NAMPT nonenzymatic function via the JNK pathway. This study shows that pulmonary epithelial cell-specific knockdown of NAMPT expression attenuated ALI, in part, via up-regulation of SFTPB expression. Thus, epithelial cell-specific knockdown of Nampt may be a potential new and viable therapeutic modality to ALI.-Bi, G., Wu, L., Huang, P., Islam, S., Heruth, D. P., Zhang, L.

PMID- 29452573 TI - The effect of Metformin treatment in obese insulin-resistant patients with euthyroid goiter. AB - Objective The study's objective was to evaluate the thyroid parameters in obese insulin-resistant patients with euthyroid diffuse or nodular goiter, following Metformin treatment. Patients and methods The study was experimental, open, and prospective. Fifty-three patients aged 18-68 were enrolled for two years. Obese insulin-resistant patients (cut-off Homeostasis-Model-Assessment of Insulin Resistance-HOMA-IR >= 2.5) with euthyroid nodular/diffuse goiter were included. Subjects with diabetes, hypo-/hyper-thyroidism, autoimmune thyroiditis, psychiatric disorders, liver or heart failure were excluded. Patients were randomly assigned to one of the following treatment: Metformin 1000 mg/day + Levothyroxine 25 MUg/day (M + LT4 group) and only Levothyroxine 25 MUg/day (LT4 group). Thyroid and metabolic parameters' evolution was investigated over six months. Results The two groups were comparable at baseline (p >= 0.10). TSH, waist/hip ratio (WHR), visceral fat thickness (VFT), insulin, and HOMA-IR decreased significantly more in M + LT4 group compared to LT4 group. TSH decrease correlated with WHR reduction (p = 0.002) only in M + LT4 group. Moreover, the multivariate regression analysis revealed that insulin's and HOMA-IR levels' decrease was an independent factor associated with FT4's increase (p = 0.031, p = 0.033) just in M + LT4 group. No other independent association between the evolution (Delta) of TSH, thyroid volume (TTV), thyroid nodules-maximum diameter (TN-MD), and metabolic parameters was found. In addition, no significant threshold between groups was reached when DeltaFT4, DeltaTTV, DeltaTN-MD were compared (p > 0.07), although their significant improvement was recorded between the baseline and the follow-up moment in each group (p < 0.003). Conclusion Metformin added to obese insulin-resistant patients treated with Levothyroxine for diffuse/nodular goiter determined a significant decrease in TSH and metabolic parameters, compared to those treated with Levothyroxine alone, but no significant difference regarding thyroid morphology after 6 months. PMID- 29452574 TI - Association of Helicobacter pylori and protozoal parasites in patients with chronic diarrhoea. AB - Introduction An association of Helicobacter pylori and common protozoal parasites in patients with abdominal discomfort and chronic diarrhoea is unclear and may be pathological. Materials and methods One hundred and sixty-one patients with diarrhoea were compared to 114 age and sex matched controls. Stool samples were examined by microscopy and DNA extracted for PCR with specific primers for H. pylori and protozoal parasites Blastocystis sp., Entamoeba sp. (Entamoeba histolytica, Entamoeba dispar and Entamoeba moshkovskii) and Giardia duodenalis (G. duodenalis). Results There was a marked difference in the presence of parasites between patients and controls: no parasite 42/75%, one parasite 42/15%, two or more parasites 16/10%, respectively (p < 0.001). Patients with diarrhoea were more likely to be infected with Blastocystis sp (p < 0.001), E. histolytica (p = 0.027) and E moshkovskii (p = 0.003). There was no difference in the frequency of H. pylori (p = 0.528), G duodenalis (p = 0.697) or E dispar (p = 0.425). Thirty-three patients and 27 controls had H. pylori infection. Of these, 22 patients and 6 controls were infected with Blastocystis sp (p = 0.001), 6 patients and no controls were infected with E. histolytica (p = 0.02), whilst 7 patents and 9 controls were infected with E dispar (p = 0.292). Conclusion In this population, diarrhoea is linked to infection with Blastocystis sp, E. histolytica and E moshkoviskii. In H. pylori infection, diarrhoea is linked to Blastocystis sp and E. histolytica infection. These associations may be linked pathogenically. PMID- 29452575 TI - A machine learning approach to detect changes in gait parameters following a fatiguing occupational task. AB - The purpose of this study is to provide a method for classifying non-fatigued vs. fatigued states following manual material handling. A method of template matching pattern recognition for feature extraction ($1 Recognizer) along with the support vector machine model for classification were applied on the kinematics of gait cycles segmented by our stepwise search-based segmentation algorithm. A single inertial measurement unit on the ankle was used, providing a minimally intrusive and inexpensive tool for monitoring. The classifier distinguished between states using distance-based scores from the recogniser and the step duration. The results of fatigue detection showed an accuracy of 90% across data from 20 recruited subjects. This method utilises the minimum amount of data and features from only one low-cost sensor to reliably classify the state of fatigue induced by a realistic manufacturing task using a simple machine learning algorithm that can be extended to real-time fatigue monitoring as a future technology to be employed in the manufacturing facilities. Practitioner Summary: We examined the use of a wearable sensor for the detection of fatigue-related changes in gait based on a simulated manual material handling task. Classification based on foot acceleration and position trajectories resulted in 90% accuracy. This method provides a practical framework for predicting realistic levels of fatigue. PMID- 29452576 TI - Assessing retention in care after 12 months of the Pediatric Development Clinic implementation in rural Rwanda: a retrospective cohort study. AB - BACKGROUND: In Africa, a high proportion of children are at risk for developmental delay. Early interventions are known to improve outcomes, but they are not routinely available. The Rwandan Ministry of Health with Partners In Health/Inshuti Mu Buzima created the Pediatric Development Clinic (PDC) model for providing interdisciplinary developmental care for high-risk infants in rural settings. As retention for chronic care has proven challenging in many settings, this study assesses factors related to retention to care after 12 months of clinic enrollment. METHODS: This study describes a retrospective cohort of children enrolled for 12 months in the PDC program in Southern Kayonza district between April 2014-March 2015. We reviewed routinely collected data from electronic medical records and patient charts. We described patient characteristics and the proportion of patients retained, died, transferred out or lost to follow up (LTFU) at 12 months. We used Fisher's exact test and multivariable logistic regression to identify factors associated with retention in care. RESULTS: 228 children enrolled in PDC from 1 April 2014-31 March 2015, with prematurity/low birth weight (62.2%) and hypoxic ischemic encephalopathy (34.5%) as the most frequent referral diagnoses. 64.5% of children were retained in care and 32.5% were LTFU after 12 months. In the unadjusted analysis, we found male sex (p = 0.189), having more children at home (p = 0.027), health facility of first visit (p = 0.006), having a PDC in the nearest health facility (p = 0.136), referral in second six months of PDC operation (p = 0.006), and social support to be associated (100%, p < 0.001) with retention after 12 months. In adjusted analysis, referral in second six months of PDC operation (Odds Ratio (OR) 2.56, 95% CI 1.36, 4.80) was associated with increased retention, and being diagnosed with more complex conditions (trisomy 21, cleft lip/palate, hydrocephalus, other developmental delay) was associated with LTFU (OR 0.34, 95% CI 0.15, 0.76). As 100% of those receiving social support were retained in care, this was not able to be assessed in adjusted analysis. CONCLUSIONS: PDC retention in care is encouraging. Provision of social assistance and decentralization of the program are major components of the delivery of services related to retention in care. PMID- 29452577 TI - Polymerase delta-interacting protein 2 deficiency protects against blood-brain barrier permeability in the ischemic brain. AB - BACKGROUND: Polymerase delta-interacting protein 2 (Poldip2) is a multifunctional protein that regulates vascular extracellular matrix composition and matrix metalloproteinase (MMP) activity. The blood-brain barrier (BBB) is a dynamic system assembled by endothelial cells, basal lamina, and perivascular astrocytes, raising the possibility that Poldip2 may be involved in maintaining its structure. We investigated the role of Poldip2 in the late BBB permeability induced by cerebral ischemia. METHODS: Transient middle cerebral artery occlusion (tMCAO) was induced in Poldip2+/+ and Poldip2+/- mice. The volume of the ischemic lesion was measured in triphenyltetrazolium chloride-stained sections. BBB breakdown was evaluated by Evans blue dye extravasation. Poldip2 protein expression was evaluated by western blotting. RT-PCR, zymography, and ELISAs were used to measure mRNA levels, activity, and protein levels of cytokines and MMPs. Cultured astrocytes were transfected with Poldip2 siRNA, and mRNA levels of cytokines were evaluated as well as IkappaBalpha protein degradation. RESULTS: Cerebral ischemia induced the expression of Poldip2. Compared to Poldip2+/+ mice, Poldip2+/- animals exhibited decreased Evans blue dye extravasation and improved survival 24 h following stroke. Poldip2 expression was upregulated in astrocytes exposed to oxygen and glucose deprivation (OGD) and siRNA-mediated downregulation of Poldip2 abrogated OGD-induced IL-6 and TNF-alpha expression. In addition, siRNA against Poldip2 inhibited TNF-alpha-induced IkappaBalpha degradation. TNF alpha, IL-6, MCP-1, VEGF, and MMP expression induced by cerebral ischemia was abrogated in Poldip2+/- mice. The protective effect of Poldip2 depletion on the increased permeability of the BBB was partially reversed by systemic administration of TNF-alpha. CONCLUSIONS: Poldip2 is upregulated following ischemic stroke and mediates the breakdown of the BBB by increasing cerebral cytokine production and MMP activation. Therefore, Poldip2 appears to be a promising novel target for the development of therapeutic strategies to prevent the development of cerebral edema in the ischemic brain. PMID- 29452578 TI - Clinical and genetic study of 20 patients from China with Cornelia de Lange syndrome. AB - BACKGROUND: Cornelia de Lange syndrome (CdLS) is a rare congenital syndrome with no racial difference. The objective of this study is to report the clinical characteristics and genetic study of 20 CdLS cases from China. METHODS: This is an observational study. Suspected patients were referred for further confirmation, clinical treatment, and genetic testing under voluntary condition. Demographic data and family history, data of clinical manifestations including facial dysmorphism and developmental delay of each patient were collected. Chromosomal analysis and NIPBL/SMC1A/SMC3 gene mutational analysis were carried out by PCR, reverse transcription PCR direct sequencing in the probands, and SNP array to detect the genome-wide copy number variations. RESULTS: Twenty CdLS cases from China were included in this study. Facial dysmorphisms, feeding difficulties, and developmental delay were the major clinical manifestations. Seven patients underwent gene mutation tests. Both the SMC1A and SMC3 gene mutation tests were negative in all. A heterozygous mutation in exon 20 of the NIPBL gene in proband 2, and a heterozygous mutation in intron 38 of the NIPBL gene in proband 3 were found in 1 patient, and RT-PCR revealed a splicing mutation in exon 38, generating both normal transcript and an aberrant alternatively spliced transcript with exon 38 deletion. CONCLUSIONS: Clinical manifestations of CdLS patients from China are similar to those in the other countries. Heterozygous mutations of NIPBL gene were found. PMID- 29452579 TI - Reliability of diagnosis and clinical efficacy of visceral osteopathy: a systematic review. AB - BACKGROUND: In 2010, the World Health Organization published benchmarks for training in osteopathy in which osteopathic visceral techniques are included. The purpose of this study was to identify and critically appraise the scientific literature concerning the reliability of diagnosis and the clinical efficacy of techniques used in visceral osteopathy. METHODS: Databases MEDLINE, OSTMED.DR, the Cochrane Library, Osteopathic Research Web, Google Scholar, Journal of American Osteopathic Association (JAOA) website, International Journal of Osteopathic Medicine (IJOM) website, and the catalog of Academie d'osteopathie de France website were searched through December 2017. Only inter-rater reliability studies including at least two raters or the intra-rater reliability studies including at least two assessments by the same rater were included. For efficacy studies, only randomized-controlled-trials (RCT) or crossover studies on unhealthy subjects (any condition, duration and outcome) were included. Risk of bias was determined using a modified version of the quality appraisal tool for studies of diagnostic reliability (QAREL) in reliability studies. For the efficacy studies, the Cochrane risk of bias tool was used to assess their methodological design. Two authors performed data extraction and analysis. RESULTS: Eight reliability studies and six efficacy studies were included. The analysis of reliability studies shows that the diagnostic techniques used in visceral osteopathy are unreliable. Regarding efficacy studies, the least biased study shows no significant difference for the main outcome. The main risks of bias found in the included studies were due to the absence of blinding of the examiners, an unsuitable statistical method or an absence of primary study outcome. CONCLUSIONS: The results of the systematic review lead us to conclude that well-conducted and sound evidence on the reliability and the efficacy of techniques in visceral osteopathy is absent. TRIAL REGISTRATION: The review is registered PROSPERO 12th of December 2016. Registration number is CRD4201605286 .

AB - BACKGROUND: What constitutes a hemodynamically relevant patent ductus arteriosus (hrPDA) in preterm infants is unclear. Different clinical and echocardiographic parameters are used, but a gold standard definition is lacking. Our objective was to evaluate associations between regional cerebral tissue oxygen saturation (rcStO2), fraction of tissue oxygen extraction (rcFtO2E) measured by frequency domain near-infrared spectroscopy (fd-NIRS) and their correlation to echocardiographic, Doppler-ultrasound, and clinical parameters in preterm infants with and without a hrPDA. METHODS: In this prospective observational study, 22 infants < 1500 g (mean [+/- SD]: gestational age 28.6 [+/-1.8] weeks, birth weight 1076 [+/-284] g, median (interquartile range) postnatal age at measurement 7.6 (4.6-12.9) d) with a clinical suspicion of hrPDA were analysed. Twelve infants had left-to-right shunt through PDA, and in 6 of these the PDA was classified as hrPDA based on pre-defined clinical and echocardiographic criteria. fd-NIRS, echocardiographic and Doppler-ultrasound examinations were performed. After identification of blood hemoglobin (Hb) as confounding factor, rcStO2 and rcFtO2E were corrected for this effect. RESULTS: Overall mean +/- standard deviation (normalised to a median Hb of 13.8 mg/dl) was 57 +/-5% for rcStO2 and 0.39 +/-0.05 for rcFtO2E. Comparing no-hrPDA with hrPDA infants, there were no significant differences in mean rcStO2 (58 +/-5% vs. 54 +/-5%; p = .102), but in mean rcFtO2E (0.38 +/-0.05 vs. 0.43 +/-0.05; p = .038). Echocardiographic parameter and Doppler indices did not correlate with cerebral oxygenation. CONCLUSION: Oxygen transport capacity of the blood may confound NIRS data interpretation. Cerebral oxygenation determined by fd-NIRS provided additional information for PDA treatment decisions not offered by routine investigations. Whether indicating PDA therapy based on echocardiography complemented by data on cerebral oxygenation results in better outcomes should be investigated in future studies.

AB - The identification of the most appropriate marker to measure reservoir size has been a great challenge for the HIV field. Quantitative viral outgrowth assay (QVOA), the reference standard to quantify the amount of replication-competent virus, has several limitations, as it is laborious, expensive, and unable to robustly reactivate every single integrated provirus. PCR-based assays have been developed as an easier, cheaper and less error-prone alternative to QVOA, but also have limitations. Historically, measuring integrated HIV DNA has provided insights about how reservoirs are formed and maintained. In the 1990s, measuring integrated HIV DNA was instrumental in understanding that a subset of resting CD4 T cells containing integrated HIV DNA were the major source of replication competent virus. Follow-up studies have further characterized the phenotype of these cells containing integrated HIV DNA, as well as shown the correlation between the integration levels and clinical parameters, such as duration of infection, CD4 count and viral load. Integrated HIV DNA correlates with total HIV measures and with QVOA. The integration assay has several limitations. First, it largely overestimates the reservoir size, as both defective and replication competent proviruses are detected. Since defective proviruses are the majority in patients on ART, it follows that the number of proviruses capable of reactivating and releasing new virions is significantly smaller than the number of integrated proviruses. Second, in patients on ART clonal expansion could theoretically lead to the preferential amplification of proviruses close to an Alu sequence though longitudinal studies have not captured this effect. Proviral sequencing combined with integration measures is probably the best estimate of reservoir size, but it is expensive, time-consuming and requires considerable bioinformatics expertise. All these reasons limit its use on a large scale. Herein, we review the utility of measuring HIV integration and suggest combining it with sequencing and total HIV measurements can provide insights that underlie reservoir maintenance. PMID- 29452582 TI - To what extent can behaviour change techniques be identified within an adaptable implementation package for primary care? A prospective directed content analysis. AB - BACKGROUND: Interpreting evaluations of complex interventions can be difficult without sufficient description of key intervention content. We aimed to develop an implementation package for primary care which could be delivered using typically available resources and could be adapted to target determinants of behaviour for each of four quality indicators: diabetes control, blood pressure control, anticoagulation for atrial fibrillation and risky prescribing. We describe the development and prospective verification of behaviour change techniques (BCTs) embedded within the adaptable implementation packages. METHODS: We used an over-lapping multi-staged process. We identified evidence-based, candidate delivery mechanisms-mainly audit and feedback, educational outreach and computerised prompts and reminders. We drew upon interviews with primary care professionals using the Theoretical Domains Framework to explore likely determinants of adherence to quality indicators. We linked determinants to candidate BCTs. With input from stakeholder panels, we prioritised likely determinants and intervention content prior to piloting the implementation packages. Our content analysis assessed the extent to which embedded BCTs could be identified within the packages and compared them across the delivery mechanisms and four quality indicators. RESULTS: Each implementation package included at least 27 out of 30 potentially applicable BCTs representing 15 of 16 BCT categories. Whilst 23 BCTs were shared across all four implementation packages (e.g. BCTs relating to feedback and comparing behaviour), some BCTs were unique to certain delivery mechanisms (e.g. 'graded tasks' and 'problem solving' for educational outreach). BCTs addressing the determinants 'environmental context' and 'social and professional roles' (e.g. 'restructuring the social and 'physical environment' and 'adding objects to the environment') were indicator specific. We found it challenging to operationalise BCTs targeting 'environmental context', 'social influences' and 'social and professional roles' within our chosen delivery mechanisms. CONCLUSION: We have demonstrated a transparent process for selecting, operationalising and verifying the BCT content in implementation packages adapted to target four quality indicators in primary care. There was considerable overlap in BCTs identified across the four indicators suggesting core BCTs can be embedded and verified within delivery mechanisms commonly available to primary care. Whilst feedback reports can include a wide range of BCTs, computerised prompts can deliver BCTs at the time of decision making, and educational outreach can allow for flexibility and individual tailoring in delivery. PMID- 29452583 TI - Does rituximab improve clinical outcomes of patients with thyroid-associated ophthalmopathy? A systematic review and meta-analysis. AB - BACKGROUND: The current therapies of thyroid-associated ophthalmopathy (TAO) were still a challenging matter. In this study, we aimed to contrast the impact of before- after rituximab (RTX) therapy in the patients with TAO. METHODS: We searched the PubMed, EMBASE, and SCOPUS databases for articles published up to July 3, 2017. Fixed- or random-effects meta-analysis was used to provide pooled estimates of standard mean difference (SMD) both the primary outcome from clinical activity score (CAS), and secondary outcomes from thyrotropin receptor antibody (TRAb), proptosis, thyroid stimulating hormone (TSH), and interleukin-6 (IL-6) levels. In addition, the quality and each study was assessed using either the Newcastle Ottawa Scale (NOS) or the Cochrane Risk of Bias tool, and reliability of the meta-analytic result using the Grading of Recommendations Assessment, Development and Evaluation (GRADE). RESULTS: Of the 839 articles initially searched, 11 studies were finally eligible for inclusion. Subgroup analysis results showed that comparing with initial value, there was a decline in CAS at 1,3,6,12 month after RTX treatment, decreased TRAbs level at 6,12 month, proptosis improvement at least 1 month, unchanged IL-6 level at 6 month, decreased TSH level at 3 month but unchanged at 12 month. All included studies were classified as good quality. CONCLUSIONS: The pooled data suggested that the preliminary effects of RTX treatment on TAO might be promising. However, more large-sample and high-quality studies targeting RTX use during this disease and long-term surveillance of prognosis are urgently needed. PMID- 29452584 TI - High phosphorus intake and gut-related parameters - results of a randomized placebo-controlled human intervention study. AB - BACKGROUND: In recent years, high phosphate intakes were discussed critically. In the small intestine, a part of the ingested phosphate and calcium precipitates to amorphous calcium phosphate (ACP), which in turn can precipitate other intestinal substances, thus leading to a beneficial modulation of the intestinal environment. Therefore, we analysed faecal samples obtained from a human intervention study regarding gut-related parameters. METHODS: Sixty-two healthy subjects (men, n = 30; women, n = 32) completed the double-blind, placebo controlled and parallel designed study (mean age: 29 +/- 7 years; mean BMI: 24 +/ 3 kg/m2). Supplements were monosodium phosphate and calcium carbonate. During the first 2 weeks, all groups consumed a placebo sherbet powder, and afterwards a sherbet powder for 8 weeks according to the intervention group: P1000/Ca0 (1000 mg/d phosphorus), P1000/Ca500 (1000 mg/d phosphorus and 500 mg/d calcium) and P1000/Ca1000 (1000 mg/d phosphorus and 1000 mg/d calcium). After the placebo period and after 8 weeks of intervention faecal collections took place. We determined in faeces: short-chain fatty acids (SCFA) and fat as well as the composition of the microbiome (subgroup) and cyto- and genotoxicity of faecal water (FW). By questionnaire evaluation we examined tolerability of the used phosphorus supplement. RESULTS: Faecal fat concentrations did not change significantly due to the interventions. Concentrations of faecal total SCFA and acetate were significantly higher after 8 weeks of P1000/Ca500 supplementation compared to the P1000/Ca0 supplementation. In men, faecal total SCFA and acetate concentrations were significantly higher after 8 weeks in the P1000/Ca1000 group compared to the P1000/Ca0 one. None of the interventions markedly affected cyto- and genotoxic activity of FW. Men of the P1000/Ca1000 intervention had a significantly different gut microbial community compared to the men of the P1000/Ca0 and P1000/Ca500 ones. The genus Clostridium XVIII was significantly more abundant in men of the P1000/Ca1000 intervention group compared to the other groups. Supplementations did not cause increased intestinal distress. CONCLUSIONS: The used high phosphorus diet did not influence cyto- and genotoxicity of FW and the concentrations of faecal fat independent of calcium intake. Our study provides first hints for a potential phosphorus-induced modulation of the gut community and the faecal total SCFA content. TRIAL REGISTRATION: The trial is registered at ClinicalTrials.gov as NCT02095392 . PMID- 29452585 TI - Beta-2 adrenergic receptors increase TREG cell suppression in an OVA-induced allergic asthma mouse model when mice are moderate aerobically exercised. AB - BACKGROUND: The potency of T regulatory (TREG) cells to inhibit T helper (Th) driven immune cell responses has been linked to increased intracellular cyclic AMP (cAMP) levels of TREG cells. In an ovalbumin (OVA)-driven allergic asthma mouse model, moderate aerobic exercise increases TREG cell function in a contact dependent manner that leads to a significant reduction in chronic inflammation and restoration of lung function. However, the mechanism, whereby exercise increases TREG function, remains unknown and was the focus of these investigations. Exercise can communicate with TREG cells by their expression of beta2-adrenergic receptors (beta2-AR). Activation of these receptors results in an increase in intracellular levels of cyclic-AMP, potentially creating a potent inhibitor of Th cell responses. RESULTS: For the allergic asthma model, female wildtype BALB/c mice were challenged with OVA, and exercised (13.5 m/min for 45 min) 3*/week for 4 weeks. TREG cells were isolated from all mouse asthma/exercise groups, including beta2-AR-/- mice, to test suppressive function and intracellular cAMP levels. In these studies, cAMP levels were increased in TREG cells isolated from exercised mice. When beta2-AR expression was absent on TREG cells, cAMP levels were significantly decreased. Correlatively, their suppressive function was compromised. Next, TREG cells from all mouse groups were tested for suppressive function after treatment with either a pharmaceutical beta2 adrenergic agonist or an effector-specific cAMP analogue. These experiments showed TREG cell function was increased when treated with either a beta2 adrenergic agonist or effector-specific cAMP analogue. Finally, female wildtype BALB/c mice were antibody-depleted of CD25+CD4+ TREG cells (anti-CD25). Twenty four hours after TREG depletion, either beta2-AR-/- or wildtype TREG cells were adoptively transferred. Recipient mice underwent the asthma/exercise protocols. beta2-AR-/- TREG cells isolated from these mice showed no increase in TREG function in response to moderate aerobic exercise. CONCLUSION: These studies offer a novel role for beta2-AR in regulating cAMP intracellular levels that can modify suppressive function in TREG cells. PMID- 29452586 TI - The role of glucocorticoid, interleukin-1beta, and antioxidants in prenatal stress effects on embryonic microglia. AB - Maternal stress during pregnancy is associated with an increased risk of psychopathology in offspring. Resident immune cells of the brain, microglia, may be mediators of prenatal stress and altered neurodevelopment. Here, we demonstrate that neither the exogenous pro-inflammatory cytokine, interleukin 1beta (IL-1beta), nor the glucocorticoid hormone, corticosterone, recapitulated the full effects of prenatal stress on the morphology of microglial cells in the cortical plate of embryonic mice; IL-1beta effects showed greater similarity to prenatal stress effects on microglia. Unexpectedly, oil vehicle alone, which has antioxidant properties, moderated the effects of prenatal stress on microglia. Microglia changes with prenatal stress were also sensitive to the antioxidant, N acetylcysteine, suggesting redox dysregulation as a mechanism of prenatal stress. PMID- 29452587 TI - Timing of abortion among adolescent and young women presenting for post-abortion care in Kenya: a cross-sectional analysis of nationally-representative data. AB - BACKGROUND: Complications of unsafe abortion are a leading cause of maternal mortality in sub-Saharan Africa. Adolescents and young women are disproportionately represented among those at risk of these complications. Currently, we know little about the factors associated with young women's timing of abortion. This study examined the timing of abortion as well as factors influencing it among adolescents and young women aged 12-24 years who sought post abortion care (PAC) in health facilities in Kenya. METHODS: We draw on data from a cross-sectional study on the magnitude and incidence of induced abortion in Kenya conducted in 2012. The study surveyed women presenting with a diagnosis of incomplete, inevitable, missed, complete, or septic abortion over a one-month data collection period in 328 health facilities (levels 2-6). Survey data, specifically, from adolescents and young women were analyzed to examine their characteristics, the timing of abortion, and the factors associated with the timing of abortion. RESULTS: One thousand one hundred forty-five adolescents and young women presented for PAC during the data collection period. Eight percent of the women reported a previous induced abortion and 78% were not using a modern method of contraception about the time of conception. Thirty-nine percent of the index abortions occurred after 12 weeks of gestation. A greater proportion of women presenting with late abortions (more than 12 weeks gestational age) (46%) than those presenting with early abortions (33%) presented with severe complications. Controlling for socio-demographic and reproductive history, timing of abortion was significantly associated with place of residence (marginal), education, parity, clinical stage of abortion and level of severity. CONCLUSIONS: Late-term abortions were substantial, and may have contributed substantially to the high proportion of women with post-abortion complications. Efforts to reduce the severity of abortion-related morbidities and mortality must target young women, particularly those living in rural and other remote areas. Interventions to reduce unintended pregnancies in this population are also urgently needed to improve early pregnancy detection and timely care seeking.

PMID- 29452589 TI - Does additional support provided through e-mail or SMS in a Web-based Social Marketing program improve children's food consumption? A Randomized Controlled Trial. AB - BACKGROUND: The FAN Social Marketing program was developed to improve dietary and physical activity habits of families with children in Ticino, Switzerland. The aim of this study was to examine if the effects of the program on children's food intake differed by intervention group. METHODS: Effects of the FAN program were tested through a Randomized Controlled Trial. The program lasted 8 weeks, during which participants received tailored communication about nutrition and physical activity. Families were randomly allocated to one of three groups, where the parent received the intervention by the Web (G1), Web + e-mail (G2) or Web + SMS (G3). Children in all groups received tailored print letters by post. Children's food consumption was assessed at baseline and immediate post intervention using a 7-day food diary. Generalized linear mixed models with child as a random effect and with time, treatment group, and the time by treatment interaction as fixed effects were used to test the impact of the intervention. RESULTS: Analyses were conducted with a sample of 608 children. After participating in FAN the marginal means of daily consumption of fruit changed from 0.95 to 1.12 in G1, from 0.82 to 0.94 in G2, and from 0.93 to 1.18 in G3. The margins of the daily consumption of sweets decreased in each group (1.67 to 1.56 in G1, 1.71 to 1.49 in G2, and 1.72 to 1.62 in G3). The change in vegetable consumption observed from pre to post intervention in G3 (from 1.13 to 1.21) was significantly different from that observed in G1 (from 1.21 to 1.17). CONCLUSIONS: A well-designed Web-based Social Marketing intervention complemented with print letters can help improve children's consumption of water, fruit, soft drinks, and sweets. The use of SMS to support greater behavior change, in addition to Web-based communication, resulted only in a small significant positive change for vegetables, while the use of e-mail in addition to Web did not result in any significant difference. TRIAL REGISTRATION: The trial was retrospectively registered in the ISRCTN registry (ID ISRCTN48730279 ). PMID- 29452590 TI - Factors associated with persistent posttraumatic stress disorder among U.S. military service members and veterans. AB - BACKGROUND: Posttraumatic stress disorder (PTSD) can have long-term and far reaching impacts on health and social and occupational functioning. This study examined factors associated with persistent PTSD among U.S. service members and veterans. METHODS: Using baseline and follow-up (2001-2013) questionnaire data collected approximately every 3 years from the Millennium Cohort Study, multivariable logistic regression was conducted to determine factors associated with persistent PTSD. Participants included those who screened positive for PTSD using the PTSD Checklist-Civilian Version at baseline (N = 2409). Participants were classified as having remitted or persistent PTSD based on screening negative or positive, respectively, at follow-up. RESULTS: Almost half of participants (N = 1132; 47%) met criteria for persistent PTSD at the first follow-up; of those, 804 (71%) also screened positive for PTSD at the second follow-up. Multiple factors were independently associated with persistent PTSD in an adjusted model at the first follow-up, including older age, deployment with high combat exposure, enlisted rank, initial PTSD severity, depression, history of physical assault, disabling injury/illness, and somatic symptoms. Among those with persistent PTSD at the first follow-up, additional factors of less sleep, separation from the military, and lack of social support were associated with persistent PTSD at the second follow-up. CONCLUSIONS: Combat experiences and PTSD severity were the most salient risk factors for persistent PTSD. Comorbid conditions, including injury/illness, somatic symptoms, and sleep problems, also played a significant role and should be addressed during treatment. The high percentage of participants with persistent PTSD supports the need for more comprehensive and accessible treatment, especially after separation from the military. PMID- 29452591 TI - Ageing-associated DNA methylation dynamics are a molecular readout of lifespan variation among mammalian species. AB - BACKGROUND: Mammalian species exhibit a wide range of lifespans. To date, a robust and dynamic molecular readout of these lifespan differences has not yet been identified. Recent studies have established the existence of ageing associated differentially methylated positions (aDMPs) in human and mouse. These are CpG sites at which DNA methylation dynamics show significant correlations with age. We hypothesise that aDMPs are pan-mammalian and are a dynamic molecular readout of lifespan variation among different mammalian species. RESULTS: A large scale integrated analysis of aDMPs in six different mammals reveals a strong negative relationship between rate of change of methylation levels at aDMPs and lifespan. This relationship also holds when comparing two different dog breeds with known differences in lifespans. In an ageing cohort of aneuploid mice carrying a complete copy of human chromosome 21, aDMPs accumulate far more rapidly than is seen in human tissues, revealing that DNA methylation at aDMP sites is largely shaped by the nuclear trans-environment and represents a robust molecular readout of the ageing cellular milieu. CONCLUSIONS: Overall, we define the first dynamic molecular readout of lifespan differences among mammalian species and propose that aDMPs will be an invaluable molecular tool for future evolutionary and mechanistic studies aimed at understanding the biological factors that determine lifespan in mammals. PMID- 29452592 TI - Considering mean and inequality health outcomes together: the population health performance index. AB - BACKGROUND: The purpose was to develop and test a population health measure that combines mean health outcomes and inequalities into a single GDP-like metric to help policymakers measure population health performance on both dimensions in one metric. METHODS: The Population Health Performance Index is a weighted average of a mean index and an inequality index according to the user's inequality aversion. We deploy this methodology for two combinations of health outcome and disparity domain: infant mortality by race and unhealthy days by education. RESULTS: The PHPI is bounded between 0 and 1, and is comprised of a weighted average of two separate indices: a mean index and an inequality index, with 1 representing the ideal state of no ill health and no inequality and 0 representing the worst state in the U.S. PHPI values across states (neutral 50:50 weighting) vary between 0.60 (Massachusetts) to 0.17 (Delaware) for infant mortality by race and between 0.65 (North Dakota) to 0.00 (West Virginia) for unhealthy days by education. For some states, the choice of inequality aversion significantly impacts their PHPI value and state rank. CONCLUSIONS: Mean and inequality health outcomes can be combined into a single Population Health Performance Index for use by public and private policy makers, like the GDP is used as a summary metric to measure economic output. The index can allow for varying degrees of inequality aversion, an individual's or jurisdiction's value choice that can substantially impact the value of this new summary population health metric. PMID- 29452594 TI - Comparative immunogenicity of preparations of yeast-derived dengue oral vaccine candidate. AB - BACKGROUND: Dengue is listed as a neglected tropical disease by the Center for Disease Control and Preservation, as there are insufficient integrated surveillance strategies, no effective treatment, and limited licensed vaccines. Consisting of four genetically distinct serotypes, dengue virus (DENV) causes serious life-threatening infections due to its complexity. Antibody-dependent enhancement by pre-existing cross-reactive as well as homotypic antibodies further worsens the clinical symptoms of dengue. Thus, a vaccine conferring simultaneous and durable immunity to each of the four DENV serotypes is essential to restrict its escalation. In deeply affected resource-limited countries, oral vaccination using food-grade organisms is considered to be a beneficial approach in terms of costs, patient comfort, and simple logistics for mass immunization. The current study used a mouse model to explore the immunogenicity of an oral dengue vaccine candidate prepared using whole recombinant yeast cells (WC) and cell-free extracts (CFE) from cells expressing recombinant Escherichia coli heat labile toxin protein B-subunit (LTB) fused to the consensus dengue envelope domain III (scEDIII). Mice were treated orally with recombinant WC and CFE vaccines in 2-week intervals for 4 weeks and changes in systemic and mucosal immune responses were monitored. RESULTS: Both WC and CFE dosage applications of LTB-scEDIII stimulated a systemic humoral immune response in the form of dengue specific serum IgG as well as mucosal immune response in the form of secretory sIgA. Antigen-specific B cell responses in isolated lymphoid cells from the spleen and Peyer's patches further indicated an elevated mucosal immune response. Cellular immune response estimated through lymphocyte proliferation assay indicated higher levels in CFE than WC dosage. Furthermore, sera obtained after both oral administrations successfully neutralized DENV-1, whereas CFE formulation only neutralized DENV-2 serotype, two representative serotypes which cause severe dengue infection. Sera from mice that were fed CFE preparations demonstrated markedly higher neutralizing titers compared to those from WC-fed mice. However, WC feeding elicited strong immune responses, which were similar to the levels induced by CFE feeding after intraperitoneal booster with purified scEDIII antigen. CONCLUSIONS: CFE preparations of LTB-scEDIII produced strong immunogenicity with low processing requirements, signifying that this fusion protein shows promise as a potent oral vaccine candidate against dengue viral infection. PMID- 29452595 TI - Fertility preservation healthcare circuit and networks in cancer patients worldwide: what are the issues? AB - BACKGROUND: Fertility preservation (FP) is a major determinant of quality of life after cancer remission for women who may not have achieved their ideal family size. This article describes the FP services and strategy currently available, highlighting issues of oncofertility worldwide. For these patients in complex situations, health networks are essential to improve coordination of care, and the strengthening of this coordination is a major challenge to improve the performance of the health system. Two international networks have been created in order to foster scientific exchange between countries and to standardize the oncofertility healthcare circuit. However, the paucity of referral nationwide networks lead to a structural gap in health care policies. SHORT CONCLUSION: Management strategies of oncofertility in the world are still fragile and uneven. To structure the oncofertility sector, a multidisciplinary project allowing teams to collaborate is of utmost importance particularly in low and middle-income countries. PMID- 29452593 TI - A review on biosynthesis of silver nanoparticles and their biocidal properties. AB - Use of silver and silver salts is as old as human civilization but the fabrication of silver nanoparticles (Ag NPs) has only recently been recognized. They have been specifically used in agriculture and medicine as antibacterial, antifungal and antioxidants. It has been demonstrated that Ag NPs arrest the growth and multiplication of many bacteria such as Bacillus cereus, Staphylococcus aureus, Citrobacter koseri, Salmonella typhii, Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumonia, Vibrio parahaemolyticus and fungus Candida albicans by binding Ag/Ag+ with the biomolecules present in the microbial cells. It has been suggested that Ag NPs produce reactive oxygen species and free radicals which cause apoptosis leading to cell death preventing their replication. Since Ag NPs are smaller than the microorganisms, they diffuse into cell and rupture the cell wall which has been shown from SEM and TEM images of the suspension containing nanoparticles and pathogens. It has also been shown that smaller nanoparticles are more toxic than the bigger ones. Ag NPs are also used in packaging to prevent damage of food products by pathogens. The toxicity of Ag NPs is dependent on the size, concentration, pH of the medium and exposure time to pathogens. PMID- 29452596 TI - Relationship between polyunsaturated fatty acid composition in serum phospholipids, systemic low-grade inflammation, and glycemic control in patients with type 2 diabetes and atherosclerotic cardiovascular disease. AB - BACKGROUND: There are inconsistent data about the role of serum phospholipid fatty acid composition in patients with type 2 diabetes (T2DM) and atherosclerotic cardiovascular disease (ASCVD). The aim of the study was to investigate the relationship between serum phospholipid fatty acid composition, systemic low-grade inflammation, and glycemic control in high-risk T2DM patients. METHODS: Seventy-four patients (26% women, mean age 65.6 +/- 6.8 years) with T2DM (median diabetes duration 10 years) and documented ASCVD (74 with coronary artery disease, 26 with peripheral arterial disease) were enrolled in the study. Baseline HbA1c was estimated using turbidimetric inhibition immunoassay. According to the median value of HbA1c the patients were grouped into those with HbA1c < 7.0% (< 53 mmol/mol) (n = 38) and those with HbA1c >= 7.0% (>= 53 mmol/mol) (n = 36). Serum phospholipid fatty acids were measured with gas chromatography. RESULTS: Patients with HbA1c >= 7.0%, compared with those with HbA1c < 7.0% had similar composition of saturated and monounsaturated fatty acids in serum phospholipids, but had higher concentrations of linoleic acid (LA) and higher n-6/n-3 polyunsaturated fatty acid (PUFA) ratio as well as lower levels of eicosapentaenoic acid (EPA), total n-3 PUFAs, and the EPA/arachidonic acid ratio. We found that LA (r = 0.25; p = 0.03) and n-6/n-3 PUFA ratio (r = 0.28; p = 0.02) were positively correlated with HbA1c. Multivariate logistic regression analysis showed that n-6/n-3 PUFA ratio, hsCRP and T2DM duration were independent predictors of worse glycemic control in patients with T2DM and ASCVD. CONCLUSIONS: This study showed that glycemic control in high-risk T2DM patients with ASCVD was significantly associated with unfavorable serum phospholipid n-6/n 3 PUFA ratio and greater systemic inflammation. PMID- 29452597 TI - Evidence of reduced treatment adherence among HIV infected paediatric and adolescent populations in Nairobi at the onset of the UNAIDS Universal Test and Treat Program. AB - OBJECTIVE: We conducted a retrospective cohort study to evaluate the efficacy of the World Health Organization (WHO) "Universal Test and Treat" (UTT) policy, initiated in Kenya in September 2016. Under this policy, every human immunodeficiency virus (HIV)-infected person should be initiated on antiretroviral therapy (ART). We compared intra- and inter-group viral suppression and ART adherence rates for pre-UTT (initiated on ART in March-August 2016) and UTT groups (initiated in September 2016). The study was conducted in a community outreach Program in Nairobi with 3500 HIV-infected children enrolled. RESULTS: 122 children and adolescents were initiated on first-line ART pre-UTT, and 197 during the UTT period. The 6 month viral suppression rate was 79.7% pre UTT versus 76.6% UTT (P < 0.05). Suboptimal adherence was higher in the UTT than pre-UTT period (88 of 197, 44.7% and 44 of 122, 34%; P < 0.001). The decrease in adherence was greater among orphans (91.7% pre-UTT and 87.2% UTT, P = 0.001) and children 11-18 years. Our results show that successful implementation of the UTT policy in Africa is challenged by an increased risk of suboptimal adherence. There is a need to develop extra strategies to support adherence, especially among orphans and teenagers. PMID- 29452598 TI - 7 versus 14 days of antibiotic treatment for critically ill patients with bloodstream infection: a pilot randomized clinical trial. AB - BACKGROUND: Shorter-duration antibiotic treatment is sufficient for a range of bacterial infections, but has not been adequately studied for bloodstream infections. Our systematic review, survey, and observational study indicated equipoise for a trial of 7 versus 14 days of antibiotic treatment for bloodstream infections; a pilot randomized clinical trial (RCT) was a necessary next step to assess feasibility of a larger trial. METHODS: We conducted an open, pilot RCT of antibiotic treatment duration among critically ill patients with bloodstream infection across 11 intensive care units (ICUs). Antibiotic selection, dosing and route were at the discretion of the treating team; patients were randomized 1:1 to intervention arms consisting of two fixed durations of treatment - 7 versus 14 days. We recruited adults with a positive blood culture yielding pathogenic bacteria identified while in ICU. We excluded patients with severe immunosuppression, foci of infection with an established requirement for prolonged treatment, single cultures with potential contaminants, or cultures yielding Staphylococcus aureus or fungi. The primary feasibility outcomes were recruitment rate and adherence to treatment duration protocol. Secondary outcomes included 90-day, ICU and hospital mortality, relapse of bacteremia, lengths of stay, mechanical ventilation and vasopressor duration, antibiotic-free days, Clostridium difficile, antibiotic adverse events, and secondary infection with antimicrobial-resistant organisms. RESULTS: We successfully achieved our target sample size (n = 115) and average recruitment rate of 1 (interquartile range (IQR) 0.3-1.5) patient/ICU/month. Adherence to treatment duration was achieved in 89/115 (77%) patients. Adherence differed by underlying source of infection: 26/31 (84%) lung; 18/29 (62%) intra-abdominal; 20/26 (77%) urinary tract; 8/9 (89%) vascular-catheter; 4/4 (100%) skin/soft tissue; 2/4 (50%) other; and 11/12 (92%) unknown sources. Patients experienced a median (IQR) 14 (8-17) antibiotic free days (of the 28 days after blood culture collection). Antimicrobial-related adverse events included hepatitis in 1 (1%) patient, Clostridium difficile infection in 4 (4%), and secondary infection with highly resistant microorganisms in 10 (9%). Ascertainment was complete for all study outcomes in ICU, in hospital and at 90 days. CONCLUSION: It is feasible to conduct a RCT to determine whether 7 versus 14 days of antibiotic treatment is associated with comparable 90-day survival.

PMID- 29452599 TI - Feasibility and acceptability of PrE-operative Physical Activity to improve patient outcomes After major cancer surgery: study protocol for a pilot randomised controlled trial (PEPA Trial). AB - BACKGROUND: There is a need for evidence of the effectiveness of pre-operative exercise for patients undergoing major cancer surgery; however, recruitment to such trials can be challenging. The PrE-operative Physical Activity (PEPA) Trial will establish the feasibility and acceptability of a pre-operative exercise programme aimed to improve patient outcomes after cytoreductive surgery and pelvic exenteration. The secondary aim is to obtain pilot data on the likely difference in key outcomes (post-operative complications, length of hospital stay, post-operative functional capacity and quality of life) to inform the sample size calculation for the substantive randomised clinical trial. METHODS/DESIGN: Twenty patients undergoing cytoreductive surgery and pelvic exenteration at the Royal Prince Alfred Hospital, Sydney will be recruited and randomly allocated (1:1 ratio) to either 2 to 6 weeks' pre-operative exercise programme (intervention group) or usual care (control group). Those randomised to the intervention group will receive up to six individualised, 1-h physiotherapy sessions (including aerobic and endurance exercises, respiratory muscle exercises, stretching and flexibility exercises), home exercises (instruction and recommendations on how to progress the exercises at home) and encouragement to be more active by using an activity tracker to measure the number of steps walked daily. Patients allocated to the control group will not receive any specific advice about exercise training. Feasibility will be assessed with consent rates to the study, and for the intervention group, retention and adherence rates to the exercise programme. Acceptability of the exercise programme will be assessed with a semi-structured questionnaire. The following measures of the effectiveness of the intervention will be collected at baseline (2 to 6 weeks pre-operative), a week before surgery, during hospital stay and pre hospital discharge: post operative complication rates (Clavien-Dindo), post-operative functional capacity (Six-minute Walk Test) and quality of life (SF-36v2(r)) and length of hospital stay. Functional status will be additionally measured using Cardiopulmonary Exercise Testing (CPET), at baseline and within a week before surgery. DISCUSSION: The PEPA Trial will provide important information about the feasibility and acceptability of a pre-operative exercise programme for patients undergoing major cancer surgery. Data from the PEPA Trial will be used to inform the design, methodology and to calculate sample size required for a larger, definitive trial.

PMID- 29452600 TI - Patterns of paediatric end-of-life care: a chart review across different care settings in Switzerland. AB - BACKGROUND: Paediatric end-of-life care is challenging and requires a high level of professional expertise. It is important that healthcare teams have a thorough understanding of paediatric subspecialties and related knowledge of disease specific aspects of paediatric end-of-life care. The aim of this study was to comprehensively describe, explore and compare current practices in paediatric end of-life care in four distinct diagnostic groups across healthcare settings including all relevant levels of healthcare providers in Switzerland. METHODS: In this nationwide retrospective chart review study, data from paediatric patients who died in the years 2011 or 2012 due to a cardiac, neurological or oncological condition, or during the neonatal period were collected in 13 hospitals, two long term institutions and 10 community-based healthcare service providers throughout Switzerland. RESULTS: Ninety-three (62%) of the 149 reviewed patients died in intensive care units, 78 (84%) of them following withdrawal of life-sustaining treatment. Reliance on invasive medical interventions was prevalent, and the use of medication was high, with a median count of 12 different drugs during the last week of life. Patients experienced an average number of 6.42 symptoms. The prevalence of various types of symptoms differed significantly among the four diagnostic groups. Overall, our study patients stayed in the hospital for a median of six days during their last four weeks of life. Seventy-two patients (48%) stayed at home for at least one day and only half of those received community-based healthcare. CONCLUSIONS: The study provides a wide-ranging overview of current end-of-life care practices in a real-life setting of different healthcare providers. The inclusion of patients with all major diagnoses leading to disease- and prematurity-related childhood deaths, as well as comparisons across the diagnostic groups, provides additional insight and understanding for healthcare professionals. The provision of specialised palliative and end-of-life care services in Switzerland, including the capacity of community healthcare services, need to be expanded to meet the specific needs of seriously ill children and their families. PMID- 29452602 TI - The quest for a framework for sustainable and institutionalised priority-setting for health research in a low-resource setting: the case of Zambia. AB - BACKGROUND: Priority-setting for health research in low-income countries remains a major challenge. While there have been efforts to systematise and improve the processes, most of the initiatives have ended up being a one-off exercise and are yet to be institutionalised. This could, in part, be attributed to the limited capacity for the priority-setting institutions to identify and fund their own research priorities, since most of the priority-setting initiatives are driven by experts. This paper reports findings from a pilot project whose aim was to develop a systematic process to identify components of a locally desirable and feasible health research priority-setting approach and to contribute to capacity strengthening for the Zambia National Health Research Authority. METHODS: Synthesis of the current literature on the approaches to health research prioritisations. The results of the synthesis were presented and discussed with a sample of Zambian researchers and decision-makers who are involved in health research priority-setting. The ultimate aim was for them to explore the different approaches available for guiding health research priority-setting and to identify an approach that would be relevant and feasible to implement and sustain within the Zambian context. RESULTS: Based on the evidence that was presented, the participants were unable to identify one approach that met the criteria. They identified attributes from the different approaches that they thought would be most appropriate and proposed a process that they deemed feasible within the Zambian context. CONCLUSION: While it is easier to implement prioritisation based on one approach that the initiator might be interested in, researchers interested in capacity-building for health research priority-setting organisations should expose the low-income country participants to all approaches. Researchers ought to be aware that sometimes one shoe may not fit all, as in the case of Zambia, instead of choosing one approach, the stakeholders may select desirable attributes from the different approaches and piece together an approach that would be feasible and acceptable within their context. An approach that builds on the decision-makers' understanding of their contexts and their input to its development would foster local ownership and has a greater potential for sustainability. PMID- 29452601 TI - Reactive hyperemia index (RHI) and cognitive performance indexes are associated with histologic markers of liver disease in subjects with non-alcoholic fatty liver disease (NAFLD): a case control study. AB - BACKGROUND: No study evaluated vascular health markers in subjects with non alcoholic fatty liver disease (NAFLD) through a combined analysis of reactive hyperemia peripheral arterial tonometry (RH-PAT) and arterial stiffness indexes. AIM OF THE STUDY: We aimed to assess whether NAFLD and its histological severity are associated with impairment of arterial stiffness and RH-PAT indexes in a mixed cohort of patients with biopsy-proven NAFLD. MATERIALS AND METHODS: The Kleiner classification was used to grade NAFLD grade. Pulse wave velocity (PWV) and augmentation index (Aix) were used as markers of arterial stiffness, whereas endothelial function was assessed using reactive hyperemia index (RHI). The mini mental state examination (MMSE) was administered to test cognitive performance. RESULTS: 80 consecutive patients with biopsy-proven NAFLD and 83 controls without fatty liver disease. NAFLD subjects showed significantly lower mean RHI, higher mean arterial stiffness indexes and lower mean MMSE score. Multivariable analysis after correction for BMI, dyslipidaemia, hypertension, sex, diabetes, age and cardiovascular disease showed that BMI, diastolic blood pressure and RHI are significantly associated to NAFLD. Simple linear regression analysis showed among non-alcoholic steatohepatitis (NASH) subjects a significant negative relationship between ballooning grade and MMSE and a significant positive association between Kleiner steatosis grade and augmentation index. CONCLUSIONS: Future research will be addressed to evaluate the relationship between inflammatory markers and arterial stiffness and endothelial function indexes in NAFLD subjects. These study will evaluate association between cardiovascular event incidence and arterial stiffness, endothelial and cognitive markers, and they will address the beneficial effects of cardiovascular drugs such as statins and ACE inhibitors on these surrogate markers in NAFLD subjects. PMID- 29452603 TI - The effects of Desflurane and Sevoflurane on Nesfatin-1 levels in laparoscopic Cholecystectomy: a randomized controlled trial. AB - BACKGROUND: Nesfatin-1 is involved in cardiovascular regulation, stress-related responses. The objective of this study is to investigate the impact of volatile anesthetics on Nesfatin-1 levels. METHOD: Fourty-two patients aged 30-65 years with the American Society Anesthesiology (ASA) Class I-II who were scheduled for laparoscopic cholecystectomy were included in the study Patients were randomized into two group; desflurane administered group (Group I, n = 21) and sevoflurane administered group (Group II, n = 21). For anesthesia maintenance, the patients received 6% desflurane or 2% sevoflurane in 40% O2 and 60% air. The patient's heart rate (HR), mean, systolic and diastolic arterial pressures (MAP, SAP, DAP), peripheral O2 saturation (SpO2) were monitored and recorded before induction, after induction, after intubation, and during extubation. Blood samples were collected before induction (T1), and after extubation when aldrete score was 10 (T2). RESULTS: Demographic data were similar between the groups. The preoperative levels of nesfatin were similar in the two groups (p = 0.715). In desflurane group, post-operative nesfatin levels were similar compared to preoperative levels (p = 0.073). In sevoflurane group, post-operative nesfatin levels were similar (p = 0.131). The nesfatin levels (postoperative vs preoperative) were similar between the groups (p = 0.900). CONCLUSION: In conclusion, this study results suggest that nesfatin-1 levels are not affected by the use of sevoflurane or desflurane in patients undergoing laparoscopic cholecystectomy.

PMID- 29452604 TI - Transcriptional regulation of ependymal cell maturation within the postnatal brain. AB - BACKGROUND: Radial glial stem cells within the developing nervous system generate a variety of post-mitotic cells, including neurons and glial cells, as well as the specialised multi-ciliated cells that line the walls of the ventricular system, the ependymal cells. Ependymal cells separate the brain parenchyma from the cerebrospinal fluid and mediate osmotic regulation, the flow of cerebrospinal fluid, and the subsequent dispersion of signalling molecules via the co-ordinated beating of their cilia. Deficits to ependymal cell development and function have been implicated in the formation of hydrocephalus, but the transcriptional mechanisms underpinning ependymal development remain poorly characterised. FINDINGS: Here, we demonstrate that the transcription factor nuclear factor IX (NFIX) plays a central role in the development of the ependymal cell layer of the lateral ventricles. Expression of ependymal cell-specific markers is delayed in the absence of Nfix. Moreover, Nfix-deficient mice exhibit aberrant ependymal cell morphology at postnatal day 15, culminating in abnormal thickening and intermittent loss of this cell layer. Finally, we reveal Foxj1, a key factor promoting ependymal cell maturation, as a target for NFIX-mediated transcriptional activation. CONCLUSIONS: Collectively, our data indicate that ependymal cell development is reliant, at least in part, on NFIX expression, further implicating this transcription factor as a mediator of multiple aspects of radial glial biology during corticogenesis. PMID- 29452605 TI - Extraordinary disease-free survival in a rare malignant extrarenal rhabdoid tumor: a case report and review of the literature. AB - BACKGROUND: Malignant extrarenal rhabdoid tumor of the gastrointestinal tract is rarely reported in the literature. It is characterized by poor prognosis and aggressive metastatic features. A literature review evidenced only 19 cases, with poor outcome. CASE PRESENTATION: We report a case of a colonic "pure" malignant extrarenal rhabdoid tumor with metastatic nodes in a 65-year-old Caucasian man. He was treated surgically with no recurrence, no adjuvant chemotherapy, and with 4-year survival without disease at the time of the submission of this article. CONCLUSIONS: We present an extraordinary case of long-term survival due to the extended surgical treatment. We believe that the absence of organ metastasis at presentation is a positive prognostic factor, although pathology confirmed node involvement (13/38 positive) on microscopy.

AB - The plasma membrane Ca2+-ATPase (PMCA) pumps play a critical role in the maintenance of calcium (Ca2+) homeostasis, crucial for optimal neuronal function and cell survival. Loss of Ca2+ homeostasis is a key precursor in neuronal dysfunction associated with brain aging and in the pathogenesis of neurodegenerative disorders. In this article, we review evidence showing age related changes in the PMCAs in synaptic plasma membranes (SPMs) and lipid raft microdomains isolated from rat brain. Both PMCA activity and protein levels decline progressively with increasing age. However, the loss of activity is disproportionate to the reduction of protein levels suggesting the presence of dysfunctional PMCA molecules in aged brain. PMCA activity is also diminished in post-mortem human brain samples from Alzheimer's disease and Parkinson's disease patients and in cell models of these neurodegenerative disorders. Experimental reduction of the PMCAs not only alter Ca2+ homeostasis but also have diverse effects on neurons such as reduced neuritic network, impaired release of neurotransmitter and increased susceptibility to stressful stimuli, particularly to agents that elevate intracellular Ca2+ [Ca2+]i. Loss of PMCA is likely to contribute to neuronal dysfunction observed in the aging brain and in the development of age-dependent neurodegenerative disorders. Therapeutic (pharmacological and/or non-pharmacological) approaches that can enhance PMCA activity and stabilize [Ca2+]i homeostasis may be capable of preventing, slowing, and/or reversing neuronal degeneration. PMID- 29452611 TI - PMCA2 pump mutations and hereditary deafness. AB - Hair cells of the inner ear detect sound stimuli, inertial or gravitational forces by deflection of their apical stereocilia. A small number of stereociliary cation-selective mechanotransduction (MET) channels admit K+ and Ca2+ ions into the cytoplasm promoting hair cell membrane depolarization and, consequently, neurotransmitter release at the cell basolateral pole. Ca2+ influx into the stereocilia compartment is counteracted by the unusual w/a splicing variant of plasma-membrane calcium-pump isoform 2 (PMCA2) which, unlike other PMCA2 variants, increases only marginally its activity in response to a rapid variation of the cytoplasmic free Ca2+ concentration ([Ca2+]c). Missense mutations of PMCA2w/a cause deafness and loss of balance in humans. Mouse models in which the pump is genetically ablated or mutated show hearing and balance impairment, which correlates with defects in homeostatic regulation of stereociliary [Ca2+]c, decreased sensitivity of mechanotransduction channels to hair bundle displacement and progressive degeneration of the organ of Corti. These results highlight a critical role played by the PMCA2w/a pump in the control of hair cell function and survival, and provide mechanistic insight into the etiology of deafness and vestibular disorders. PMID- 29452612 TI - Survival strategies for mouse cerebellar Purkinje neurons lacking PMCA2. AB - Expression of the fast calcium extrusion protein, PMCA2, in the cerebellum is amongst the highest found throughout the central nervous system, and unsurprisingly PMCA2 knockout mice exhibit cerebellar ataxia or loss of controlled movement. The sole output neurons of the cerebellar cortex, Purkinje neurons, are functionally compromised in these knockout mice, yet remarkably these neurons survive. In this mini-review we review and speculate on the importance of multiple PMCA2 dependent actions at cellular and synaptic sites within the cerebellar Purkinje neuron network. We also explore how loss of PMCA2 /- can lead to the ataxic phenotype, but can paradoxically also minimise calcium rises in cerebellar Purkinje neurons, thereby ensuring their resilience and survival. PMID- 29452613 TI - The role of Plasma Membrane Calcium ATPases (PMCAs) in neurodegenerative disorders. AB - Selective degeneration of differentiated neurons in the brain is the unifying feature of neurodegenerative disorders such as Parkinson's disease (PD) or Alzheimer's disease (AD). A broad spectrum of evidence indicates that initially subtle, but temporally early calcium dysregulation may be central to the selective neuronal vulnerability observed in these slowly progressing, chronic disorders. Moreover, it has long been evident that excitotoxicity and its major toxic effector mechanism, neuronal calcium overload, play a decisive role in the propagation of secondary neuronal death after acute brain injury from trauma or ischemia. Under physiological conditions, neuronal calcium homeostasis is maintained by a fine-tuned interplay between calcium influx and releasing mechanisms (Ca2+-channels), and calcium efflux mechanisms (Ca2+-pumps and exchangers). Central functional components of the calcium efflux machinery are the Plasma Membrane Calcium ATPases (PMCAs), which represent high-affinity calcium pumps responsible for the ATP-dependent removal of calcium out of the cytosol. Beyond a growing body of experimental evidence, it is their high expression level, their independence of secondary ions or membrane potential, their profound redox regulation and autoregulation, their postsynaptic localization in close proximity to the primary mediators of pathological calcium influx, i.e. NMDA receptors, as well as evolutionary considerations which all suggest a pivotal role of the PMCAs in the etiology of neurodegeneration and make them equally challenging and alluring candidates for drug development. This review aims to summarize the recent literature on the role of PMCAs in the pathogenesis of neurodegenerative disorders.

AB - Fever of unknown origin (FUO) is commonly defined as fever higher than 38.3 degrees C on several occasions during at least 3 weeks with uncertain diagnosis after a number of obligatory investigations. The differential diagnosis of FUO can be subdivided in four categories: infections, malignancies, noninfectious inflammatory diseases, and miscellaneous causes. In most cases of FUO, there is an uncommon presentation of a common disease. FDG-PET/CT is a sensitive diagnostic technique for the evaluation of FUO by facilitating anatomical localization of focally increased FDG uptake, thereby guiding further diagnostic tests to achieve a final diagnosis. FDG-PET/CT should become a routine procedure in the workup of FUO when diagnostic clues are absent. FDG-PET/CT appears to be a cost-effective routine imaging technique in FUO by avoiding unnecessary investigations and reducing the duration of hospitalization. PMID- 29452616 TI - Tuberculosis. AB - Tuberculosis (TB) is currently the world's leading cause of infectious mortality. Imaging plays an important role in the management of this disease. The complex immune response of the human body to Mycobacterium tuberculosis results in a wide array of clinical manifestations, making clinical and radiological diagnosis challenging. 18F-FDG-PET/CT is very sensitive in the early detection of TB in most parts of the body; however, the lack of specificity is a major limitation. 18F-FDG-PET/CT images the whole body and provides a pre-therapeutic metabolic map of the infection, enabling clinicians to accurately assess the burden of disease. It enables the most appropriate site of biopsy to be selected, stages the infection, and detects disease in previously unknown sites. 18F-FDG-PET/CT has recently been shown to be able to identify a subset of patients with latent TB infection who have subclinical disease. Lung inflammation as detected by 18F-FDG PET/CT has shown promising signs that it may be a useful predictor of progression from latent to active infection. A number of studies have identified imaging features that might improve the specificity of 18F-FDG-PET/CT at some sites of extrapulmonary TB. Other PET tracers have also been investigated for their use in TB, with some promising results. The potential role and future perspectives of PET/CT in imaging TB is considered. Literature abounds on the very important role of 18F-FDG-PET/CT in assessing therapy response in TB. The use of 18F-FDG for monitoring response to treatment is addressed in a separate review. PMID- 29452617 TI - Imaging of Spondylodiscitis. AB - Spondylodiscitis is an infection of the vertebral body or disc and may also involve the epidural space, posterior elements, and paraspinal soft tissues. It is a cause of morbidity and mortality, and warrants early diagnosis and prompt treatment. Diagnosis can be difficult because of nonspecific signs and symptoms. Magnetic resonance imaging is sensitive and specific and is the imaging modality of choice for spondylodiscitis. Gadolinium contrast can show the extent of soft tissue and bone phlegmon and abscess. The test is less useful for evaluating treatment response. When magnetic resonance imaging cannot be performed or is not diagnostic, radionuclide imaging is a useful alternative. Although bone scintigraphy frequently is used as a screening test, false-negative results can occur, especially in the elderly. This test is not useful for detecting soft tissue infections that accompany or mimic spondylodiscitis. Gallium-67 citrate improves the specificity of the bone scan, can detect infection earlier than the bone scan, may be more sensitive, especially in elderly patients, and identifies accompanying soft tissue infection. Performing SPECT and SPECT/CT improves accuracy. The 2- to 3-day delay between radiopharmaceutical administration and the relatively poor image quality are significant disadvantages of gallium-67. Indium-111 biotin, alone or in combination with streptavidin, accurately diagnoses spondylodiscitis; unfortunately, this agent is not widely available. Currently, 18F-FDG imaging is the radionuclide test of choice for spondylodiscitis. The procedure, which is completed in a single session, is sensitive, has a high negative predictive value, and reliably differentiates degenerative from infectious vertebral body end plate abnormalities. In comparative investigations, 18F-FDG has outperformed bone and gallium-67 imaging. Preliminary data suggest that 18F-FDG may be able to provide an objective means to measure response to treatment. Gallium-68 citrate and 99mTc-radiolabeled antimicrobial peptides have been investigated, but their role in spondylodiscitis has yet to be established. PMID- 29452618 TI - Radionuclide Imaging of Infection and Inflammation in Children: a Review. AB - With the exception of radiolabeled monoclonal antibodies, antibody fragments and radiolabeled peptides which have seen little application in the pediatric population, the nuclear medicine imaging procedures used in the evaluation of infection and inflammation are the same for both adults and children. These procedures include (1) either a two- or a three-phase bone scan using technetium 99m methylene diphosphonate; (2) Gallium 67-citrate; (3) in vitro radiolabeled white blood cell imaging (using 111Indium-oxine or 99mTechnetium hexamethyl propylene-amine-oxime-labeled white blood cells); and (4) hybrid imaging with 18F FDG. But children are not just small adults. Not only are the disease processes encountered in children different from those in adults, but there are developmental variants that can mimic, but should not be confused with, pathology. This article discusses some of the differences between adults and children with osteomyelitis, illustrates several of the common developmental variants that can mimic disease, and, finally, focuses on the increasing use of 18F-FDG PET/CT in the diagnosis and response monitoring of children with infectious and inflammatory processes. The value of and need for pediatric specific imaging protocols are reviewed. PMID- 29452619 TI - Monitoring Response to Therapy. AB - Monitoring response to treatment is a key element in the management of infectious diseases, yet controversies still persist on reliable biomarkers for noninvasive response evaluation. Considering the limitations of invasiveness of most diagnostic procedures and the issue of expression heterogeneity of pathology, molecular imaging is better able to assay in vivo biologic processes noninvasively and quantitatively. The usefulness of 18F-FDG-PET/CT in assessing treatment response in infectious diseases is more promising than for conventional imaging. However, there are currently no clinical criteria or recommended imaging modalities to objectively evaluate the effectiveness of antimicrobial treatment. Therapeutic effectiveness is currently gauged by the patient's subjective clinical response. In this review, we present the current studies for monitoring treatment response, with a focus on Mycobacterium tuberculosis, as it remains a major worldwide cause of morbidity and mortality. The role of molecular imaging in monitoring other infections including spondylodiscitis, infected prosthetic vascular grafts, invasive fungal infections, and a parasitic disease is highlighted. The role of functional imaging in monitoring lipodystrophy associated with highly active antiretroviral therapy for human immunodeficiency virus is considered. We also discuss the key challenges and emerging data in optimizing noninvasive response evaluation. PMID- 29452621 TI - Letter from the Editors. PMID- 29452622 TI - Letter from the Guest Editor. PMID- 29452623 TI - Currently Available Radiopharmaceuticals for Imaging Infection and the Holy Grail. AB - Infection is ubiquitous. However, its management is challenging for both the patients and the health-care providers. Scintigraphic imaging of infection dates back nearly half a century. The advances in our understanding of the pathophysiology of disease at cellular and molecular levels have paved the way to the development of a large number of radiopharmaceuticals for scintigraphic imaging of infection. These include radiolabeling of blood elements such as serum proteins, white blood cells (WBCs), and cytokines, to name a few. Infectious foci have also been imaged using a radiolabeled sugar molecule by taking advantage of increased metabolic activity in the infectious lesions. Literature over the years has well documented that none of the radiopharmaceuticals and associated procedures that facilitate imaging infection are flawless and acceptable without a compromise. As a result, only a few compounds such as 99mTc hexamethylpropyleneamineoxime, 18F-FDG, the oldest but still considered as a gold standard 111In-oxine, and, yes, even 67Ga-citrate in some countries, have remained in routine clinical practice. Nonetheless, the interest of scientists and physicians to improve the approaches to imaging and to the management of infection is noteworthy. These approaches have paved the way for the development of numerous, innovative radiopharmaceuticals to label autologous WBCs ex vivo or even those that could be injected directly to image infection or inflammation without direct involvement of WBCs. In this review, we briefly describe these agents with their pros and cons and place them together for future reference. PMID- 29452620 TI - Pathogen-Specific Bacterial Imaging in Nuclear Medicine. AB - When serious infections are suspected, patients are often treated empirically with broad-spectrum antibiotics while awaiting results that provide information on the bacterial class and species causing the infection, as well as drug susceptibilities. For deep-seated infections, these traditional diagnostic techniques often rely on tissue biopsies to obtain clinical samples which can be expensive, dangerous, and has the potential of sampling bias. Moreover, these procedures and results can take several days and may not always provide reliable information. This combination of time and effort required for proper antibiotic selection has become a barrier leading to indiscriminate broad-spectrum antibiotic use. Exposure to nosocomial infections and indiscriminate use of broad spectrum antibiotics are responsible for promoting bacterial drug-resistance leading to substantial morbidity and mortality, especially in hospitalized and immunosuppressed patients. Therefore, early diagnosis of infection and targeted antibiotic treatments are urgently needed to reduce morbidity and mortality caused by bacterial infections worldwide. Reliable pathogen-specific bacterial imaging techniques have the potential to provide early diagnosis and guide antibiotic treatments. PMID- 29452624 TI - From the Editor's Perspective.... PMID- 29452625 TI - Knowledge regarding noncytotoxic medication extravasation among registered nurses working in western Saudi Arabia. AB - Extravasation and infiltration are among the most common intravenous therapy complications. For noncytotoxic agents, the incidence of extravasation remains unknown. There has been little research into extravasation due to ethical considerations limiting controlled research; most evidences are based on small, uncontrolled trials or case reports. The purpose of this study was to assess the knowledge level regarding noncytotoxic medications extravasation and its associated factors among staff nurses.A descriptive correlational design using self-administered questionnaire was employed. A convenience sample of 387 nurses completed a questionnaire about noncytotoxic medication extravasation. Statistical Package for Social Sciences version 21 was used to analyze data by applying the chi-square test, t test, and the Mann-Whitney test to assess the knowledge difference between open and closed units' nurses.The results indicate that only 19.6% of nurses have a good knowledge about noncytotoxic medications extravasation. There was consistently poor staff knowledge regarding noncytotoxic medications extravasation. Although the closed units' nurses reported relatively higher level of knowledge than open units' nurses, their level of knowledge still inadequate. Health care organizations must consider developing specific policies regarding extravasation. Closed and open units' nurses should be enrolled in special education programs to improve their level of knowledge regarding noncytotoxic medication extravasation. PMID- 29452627 TI - Case series of 18 patients with lower extremity wounds treated with a concentrated surfactant-based gel dressing. AB - The purpose of this case series was to assess the performance of a concentrated surfactant-based gel (CSG) dressing on 18 patients in the outpatient setting over 4 weeks. Wounds selected were full thickness, had been presented for greater than 4 weeks, and were located on the lower extremities. Patients were given the CSG dressing and instructed on its use. On follow-up clinic visits, the wound was assessed, measurements were obtained, Pressure Ulcer Scale for Healing (PUSH) Tool scores completed, and satisfaction with the dressing was solicited. Individual analysis of each subject's wound was conducted to determine if there was a healing trend over time with a decrease in total PUSH score. Descriptive statistics were used to analyze the results. Eighteen patients participated in this case series involving 9 women and 9 men with a mean age of 66 years (range from 52 to 91). All 18 of the patients had a primary diagnosis of peripheral vascular disease with 7 patients having venous leg ulcers and 11 patients with lower extremity arterial ulcers. The mean Total PUSH score before the CSG dressing was applied was 10.7 (range from 5 to 15) (standard deviation [SD] 3.09) and posttreatment was 8.3 (range from 0 to 14) (SD 4).

AB - The purpose of this study was to implement and evaluate quality outcomes including referral, enrollment, and completion rates of a new peripheral artery disease (PAD)-specific supervised exercise therapy (SET) program within a preexisting clinical exercise wellness program and to evaluate the clinical effectiveness and patient-centered outcomes derived from 12 weeks of PAD-specific SET. Recruited participants completed an individualized, minimally supervised, PAD-specific SET program based on the AHA-ACC guidelines. Exercise workloads (metabolic equivalents of task [METs]) were tracked and evaluated throughout the program. Short Physical Performance Battery, 6-minute walk test (6MWT) Walking Impairment Questionnaire, Short-Form 36 (SF-36), and Peripheral Artery Disease Quality of Life Questionnaire (PADQOL) were assessed before and after the program. Paired t-tests were used to examine differences between baseline and follow-up outcome variables. On average, participants (n = 46) attended 23 (standard deviation [SD] 12.9) out of the possible 36 training sessions, for a 64% attendance rate. Among participants who used treadmill walking as the primary mode of exercise (n = 40), the overall mean MET level just prior to program completion was 3.79 (SD 1.49), which represented an increase of 0.92 (34%) METs compared to baseline (P < .001). Total distance on the 6MWT increased 115 (11%) feet (P = .011), which is considered a clinically meaningful improvement. Significant improvements were noted in the PADQOL: symptoms and limitations in physical functioning (P = .007). This study demonstrates that a minimally staffed PAD-specific SET program can improve functional performance in patients with claudication due to PAD and serves as a foundation to help build a clinically effective, Centers for Medicare and Medicaid reimbursed PAD-specific rehabilitation program. PMID- 29452628 TI - An integrative review of peer support for patients undergoing major limb amputation. AB - Medical literature is replete with evidence regarding physical rehabilitation of the amputee; however, scant attention has been paid to psychological rehabilitation. The objective was to perform an integrative review of the published medical evidence regarding amputee peer support in the civilian population and provide an evidence-based clinical practice recommendation. This study was based on an exhaustive examination of the civilian amputee peer support medical evidence, bibliographic search, and on the experience of the authors when performing this integrative review. Our search uncovered 10 published peer reviewed pieces of medical evidence including one level III retrospective case controlled trial, two level IV case series, and seven level V expert opinions. Given the totality of the published evidence, albeit limited, in favor of amputee peer support, an abundance of unpublished anecdotal evidence, virtually no potential risk of harm, and low cost, it seems reasonable to recommend incorporating a preoperative and/or postoperative peer visit in clinical protocols for all patients incurring a major limb amputation. PMID- 29452629 TI - Continuous betadine-bacitracin irrigation for vascular graft infections: A case series. AB - The aim of the study was to conduct a retrospective chart review of patients who underwent betadine/bacitracin continuous irrigation (BBCI) for vascular graft infections (VGIs) to review its use as a treatment option. A retrospective chart review from 2013 to 2017 was conducted of patients with VGIs that were treated with BBCI postremoval of the infected graft. The BBCI is a continuous infusion of 0.25% betadine in normal saline at 0.3 mL/kg/h for 48 hours then followed by bacitracin infusion with a concentration of 50,000 units bacitracin/per liter normal saline at 0.3 mL/kg/h for 72 hours. Descriptive statistics were used to describe the sample. The nine adult patients who received postoperative BBCI had an age range of 30-81 years, with average age of 58.8 years. Five of the subjects were females with four males. A total of nine patients with groin infections were identified, with two aortobifemoral bypasses, two axillofemoral bypasses, three femoral-femoral bypasses, one femoral artery pseudoaneurysm repair with Dacron patch, and one common femoral endarterectomy with Dacron patch. VGIs were identified from 10 days up to 72 months from the original vascular procedure. Six patients had negative wound cultures, while two had wound cultures positive for methicillin-resistant Staphylococcus aureus and one patient had positive culture for Escherichia coli. The length of time of BBCI ranged from 48 to 84 hours with average of 57.6 hours (standard deviation [SD] = 12.7 hours). The length of time of the bacitracin irrigation ranged from 30 to 72 hours with average of 48.4 hours (SD = 14.9 hours). All patients healed their groin wounds except for an 81 year-old patient with aortobifemoral bypass graft who developed ischemic bowel and expired. Patients received at least 6 weeks of intravenous antibiotics followed by oral antibiotic suppression therapy for life. VGIs are a devastating complication associated with a high morbidity. BBCI provides an option for antiseptic irrigation of the vascular graft site postgraft removal to promote wound closure.

PMID- 29452631 TI - The evaluation of the implementation of the vascular preventative bundle and development of suggested interventions for improvement and sustainability. AB - Postoperative infections can complicate patient care and increase health care costs. A vascular preventative bundle was implemented at a large teaching/research intensive hospital to decrease surgical site infections (SSIs) with vascular surgery patients. The aim of this study was to measure fidelity to the bundle and determine if implementation of the vascular SSI bundle reduced the rate of SSIs. Three periods of data were collected, and they are identified as preimplementation (period 1), early implementation (period 2), and postimplementation (period 3). There were 711 patients for all three periods, approximately equally distributed in the periods. The use of preoperative hair clippings, chlorhexidine (CHG) wipes, and appropriate antibiotics showed the greatest improvement from preimplementation to early implementation. All three measures showed significant improvements in fidelity. For appropriate antibiotics, the fidelity was the highest and showed the largest improvement compared to the other measures. The performance of clippings preoperatively and using CHG wipes improved significantly. Evidence-based interventions have been recommended to support the implementation and sustainability of the bundle. The infection rate between preop and postperiod was not statistically different.

PMID- 29452635 TI - The Circulating Protease Persephone Is an Immune Sensor for Microbial Proteolytic Activities Upstream of the Drosophila Toll Pathway. AB - Microbial or endogenous molecular patterns as well as pathogen functional features can activate innate immune systems. Whereas detection of infection by pattern recognition receptors has been investigated in details, sensing of virulence factors activities remains less characterized. In Drosophila, genetic evidences indicate that the serine protease Persephone belongs to a danger pathway activated by abnormal proteolytic activities to induce Toll signaling. However, neither the activation mechanism of this pathway nor its specificity has been determined. Here, we identify a unique region in the pro-domain of Persephone that functions as bait for exogenous proteases independently of their origin, type, or specificity. Cleavage in this bait region constitutes the first step of a sequential activation and licenses the subsequent maturation of Persephone to the endogenous cysteine cathepsin 26-29-p. Our results establish Persephone itself as an immune receptor able to sense a broad range of microbes through virulence factor activities rather than molecular patterns. PMID- 29452636 TI - Disruption of XIAP-RIP2 Association Blocks NOD2-Mediated Inflammatory Signaling. AB - Inflammatory responses mediated by NOD2 rely on RIP2 kinase and ubiquitin ligase XIAP for the activation of nuclear factor kappaB (NF-kappaB), mitogen-activated protein kinases (MAPKs), and cytokine production. Herein, we demonstrate that selective XIAP antagonism blocks NOD2-mediated inflammatory signaling and cytokine production by interfering with XIAP-RIP2 binding, which removes XIAP from its ubiquitination substrate RIP2. We also establish that the kinase activity of RIP2 is dispensable for NOD2 signaling. Rather, the conformation of the RIP2 kinase domain functions to regulate binding to the XIAP-BIR2 domain. Effective RIP2 kinase inhibitors block NOD2 signaling by disrupting RIP2-XIAP interaction. Finally, we identify NOD2 signaling and XIAP-dependent ubiquitination sites on RIP2 and show that mutating these lysine residues adversely affects NOD2 pathway signaling. Overall, these results reveal a critical role for the XIAP-RIP2 interaction in NOD2 inflammatory signaling and provide a molecular basis for the design of innovative therapeutic strategies based on XIAP antagonists and RIP2 kinase inhibitors. PMID- 29452637 TI - Ubiquitin-Mediated Regulation of RIPK1 Kinase Activity Independent of IKK and MK2. AB - Tumor necrosis factor (TNF) can drive inflammation, cell survival, and death. While ubiquitylation-, phosphorylation-, and nuclear factor kappaB (NF-kappaB) dependent checkpoints suppress the cytotoxic potential of TNF, it remains unclear whether ubiquitylation can directly repress TNF-induced death. Here, we show that ubiquitylation regulates RIPK1's cytotoxic potential not only via activation of downstream kinases and NF-kB transcriptional responses, but also by directly repressing RIPK1 kinase activity via ubiquitin-dependent inactivation. We find that the ubiquitin-associated (UBA) domain of cellular inhibitor of apoptosis (cIAP)1 is required for optimal ubiquitin-lysine occupancy and K48 ubiquitylation of RIPK1. Independently of IKK and MK2, cIAP1-mediated and UBA-assisted ubiquitylation suppresses RIPK1 kinase auto-activation and, in addition, marks it for proteasomal degradation. In the absence of a functional UBA domain of cIAP1, more active RIPK1 kinase accumulates in response to TNF, causing RIPK1 kinase mediated cell death and systemic inflammatory response syndrome. These results reveal a direct role for cIAP-mediated ubiquitylation in controlling RIPK1 kinase activity and preventing TNF-mediated cytotoxicity. PMID- 29452638 TI - NADH Shuttling Couples Cytosolic Reductive Carboxylation of Glutamine with Glycolysis in Cells with Mitochondrial Dysfunction. AB - The bioenergetics and molecular determinants of the metabolic response to mitochondrial dysfunction are incompletely understood, in part due to a lack of appropriate isogenic cellular models of primary mitochondrial defects. Here, we capitalize on a recently developed cell model with defined levels of m.8993T>G mutation heteroplasmy, mTUNE, to investigate the metabolic underpinnings of mitochondrial dysfunction. We found that impaired utilization of reduced nicotinamide adenine dinucleotide (NADH) by the mitochondrial respiratory chain leads to cytosolic reductive carboxylation of glutamine as a new mechanism for cytosol-confined NADH recycling supported by malate dehydrogenase 1 (MDH1). We also observed that increased glycolysis in cells with mitochondrial dysfunction is associated with increased cell migration in an MDH1-dependent fashion. Our results describe a novel link between glycolysis and mitochondrial dysfunction mediated by reductive carboxylation of glutamine. PMID- 29452639 TI - Mitochondrial MDM2 Regulates Respiratory Complex I Activity Independently of p53. AB - Accumulating evidence indicates that the MDM2 oncoprotein promotes tumorigenesis beyond its canonical negative effects on the p53 tumor suppressor, but these p53 independent functions remain poorly understood. Here, we show that a fraction of endogenous MDM2 is actively imported in mitochondria to control respiration and mitochondrial dynamics independently of p53. Mitochondrial MDM2 represses the transcription of NADH-dehydrogenase 6 (MT-ND6) in vitro and in vivo, impinging on respiratory complex I activity and enhancing mitochondrial ROS production. Recruitment of MDM2 to mitochondria increases during oxidative stress and hypoxia. Accordingly, mice lacking MDM2 in skeletal muscles exhibit higher MT-ND6 levels, enhanced complex I activity, and increased muscular endurance in mild hypoxic conditions. Furthermore, increased mitochondrial MDM2 levels enhance the migratory and invasive properties of cancer cells. Collectively, these data uncover a previously unsuspected function of the MDM2 oncoprotein in mitochondria that play critical roles in skeletal muscle physiology and may contribute to tumor progression. PMID- 29452641 TI - Cdc48/VCP Promotes Chromosome Morphogenesis by Releasing Condensin from Self Entrapment in Chromatin. AB - The morphological transformation of amorphous chromatin into distinct chromosomes is a hallmark of mitosis. To achieve this, chromatin must be compacted and remodeled by a ring-shaped enzyme complex known as condensin. However, the mechanistic basis underpinning condensin's role in chromosome remodeling has remained elusive. Here we show that condensin has a strong tendency to trap itself in its own reaction product during chromatin compaction and yet is capable of interacting with chromatin in a highly dynamic manner in vivo. To resolve this apparent paradox, we identified specific chromatin remodelers and AAA-class ATPases that act in a coordinated manner to release condensin from chromatin entrapment. The Cdc48 segregase is the central linchpin of this regulatory mechanism and promotes ubiquitin-dependent cycling of condensin on mitotic chromatin as well as effective chromosome condensation. Collectively, our results show that condensin inhibition by its own reaction product is relieved by forceful enzyme extraction from chromatin. PMID- 29452640 TI - Serine Catabolism by SHMT2 Is Required for Proper Mitochondrial Translation Initiation and Maintenance of Formylmethionyl-tRNAs. AB - Upon glucose restriction, eukaryotic cells upregulate oxidative metabolism to maintain homeostasis. Using genetic screens, we find that the mitochondrial serine hydroxymethyltransferase (SHMT2) is required for robust mitochondrial oxygen consumption and low glucose proliferation. SHMT2 catalyzes the first step in mitochondrial one-carbon metabolism, which, particularly in proliferating cells, produces tetrahydrofolate (THF)-conjugated one-carbon units used in cytoplasmic reactions despite the presence of a parallel cytoplasmic pathway. Impairing cytoplasmic one-carbon metabolism or blocking efflux of one-carbon units from mitochondria does not phenocopy SHMT2 loss, indicating that a mitochondrial THF cofactor is responsible for the observed phenotype. The enzyme MTFMT utilizes one such cofactor, 10-formyl THF, producing formylmethionyl-tRNAs, specialized initiator tRNAs necessary for proper translation of mitochondrially encoded proteins. Accordingly, SHMT2 null cells specifically fail to maintain formylmethionyl-tRNA pools and mitochondrially encoded proteins, phenotypes similar to those observed in MTFMT-deficient patients. These findings provide a rationale for maintaining a compartmentalized one-carbon pathway in mitochondria. PMID- 29452645 TI - Patient-Reported Outcomes in Esophageal Diseases. PMID- 29452643 TI - Combinatorial CRISPR-Cas9 Metabolic Screens Reveal Critical Redox Control Points Dependent on the KEAP1-NRF2 Regulatory Axis. AB - The metabolic pathways fueling tumor growth have been well characterized, but the specific impact of transforming events on network topology and enzyme essentiality remains poorly understood. To this end, we performed combinatorial CRISPR-Cas9 screens on a set of 51 carbohydrate metabolism genes that represent glycolysis and the pentose phosphate pathway (PPP). This high-throughput methodology enabled systems-level interrogation of metabolic gene dispensability, interactions, and compensation across multiple cell types. The metabolic impact of specific combinatorial knockouts was validated using 13C and 2H isotope tracing, and these assays together revealed key nodes controlling redox homeostasis along the KEAP-NRF2 signaling axis. Specifically, targeting KEAP1 in combination with oxidative PPP genes mitigated the deleterious effects of these knockouts on growth rates. These results demonstrate how our integrated framework, combining genetic, transcriptomic, and flux measurements, can improve elucidation of metabolic network alterations and guide precision targeting of metabolic vulnerabilities based on tumor genetics.

AB - The yeast INO80 chromatin remodeling complex plays essential roles in regulating DNA damage repair, replication, and promoter architecture. INO80's role in these processes is likely related to its ability to slide nucleosomes, but the underlying mechanism is poorly understood. Here we use ensemble and single molecule enzymology to study INO80-catalyzed nucleosome sliding. We find that the rate of nucleosome sliding by INO80 increases ~100-fold when the flanking DNA length is increased from 40 to 60 bp. Furthermore, once sliding is initiated, INO80 moves the nucleosome rapidly at least 20 bp without pausing to re-assess flanking DNA length, and it can change the direction of nucleosome sliding without dissociation. Finally, we show that the Nhp10 module of INO80 plays an auto-inhibitory role, tuning INO80's switch-like response to flanking DNA. Our results indicate that INO80 is a highly processive remodeling motor that is tightly regulated by both substrate cues and non-catalytic subunits.

AB - Post-inflammatory hyperpigmentation (PIH) is a hyperpigmentation of the skin occurring after and sometimes during an inflammatory process. Although more frequent in dark skinned individuals, PIH can be observed in any type of skin and at all ages. In most case a strong impact on the quality of life of affected individuals is observed. The pathophysiology of PIH remains largely unknown. The activation of the melanocytes occurs in the first week following the inflammation emphasizing the crucial role of early preventive measures. Photoprotection with balanced UVA and UVB protection is required. Visible light could also play a role in PIH but this remains to be demonstrated. Healing topics with anti-inflammatory properties are of interest after a skin procedure. When the risk of PIH is high or when PIH occurs, topical steroids remains the gold standard approach. PMID- 29452654 TI - [Dermatosurgery and other interventional techniques in dermatology: a more than 2000 year-history]. AB - Surgical dermatology has probably existed since the first steps of antique medicine, especially for cutaneous cancer excision and wound reparation. Wonderful descriptions of surgical flaps can be found in the Encyclopedy of Celse, a Roman doctor living in the first century AC. Major progresses in local anesthesy were achieved at the end of the XIXth century, allowing the first dermatologists of the XXth century to perform biopsies and cutaneous surgery with a good control of patient's pain. Electricity was introduced in medicine at the end of the XIXth century, and our ancestors dermatologists used it for electrocoagulation, cauterization and electric hair removal. In the " Pratique dermatologique ", the first encyclopedy of dermatology published in 1900, many chapters show how important instrumental and surgical dermatology was. Pigmentary changes induced by surgery and other procedures were probably well known then but were less important than troubles due to scarring, which are mentioned in the early literature. Spontaneous or post-interventional cheloids are well discussed in the early works of Alibert, in the years 1810. This article shows that surgical dermatology is far more ancient than the creation of societies dedicated to it in the XXth century. PMID- 29452655 TI - [How to optimize scarring in dermatologic surgery?] AB - Scarring is the response elicited by the skin surface to injury and loss of tissue material. Wound healing takes place through a complex natural repair system consisting of vascular, inflammatory and proliferative phenomena, followed by a remodelling and cell apoptosis phase. This incredible repair system is inevitable, but sometimes unpredictable due to individual differences based on multiple factors. The scar is the objective criterion of a skin surgery, both for the patient and the dermsurgeon. It is therefore crucial to establish with the patient during the preoperative consultation, the size and positioning of the expected scar, taking into account the oncologic, anatomic and surgical constraints. Scars can ideally blend into normal skin, but may also give rise to various abnormalities. We can manage and prevent these abnormalities by mastering initial inflammation, that may induce hyperpigmentation and hypertrophy. Early massage using cortocosteroid topic or anti-inflammatory moisturizers may be effective. Random individual scarring may be minimized by a dynamic personalized accompanying scarring. PMID- 29452656 TI - [Optimization of the healing process after laser procedure, except photorejuvenation]. AB - The use of Lasers in dermatology implies a crucial follow-up in order to optimize the final result and avoid any side effects. With the use of ablative laser devices, the initial phase is characterized by the development of crusts. These crusts necessitate the application of sterile ointments (regularly repeated throughout the day) as well as an antibiotic ointment two times a day. In a second step, comes a secondary inflammatory state, in the dermis, which is generally observed at the outset of all other laser treatments. The main purpose is to avoid it from being too sustained over time, but also to prevent the occurrence of post inflammatory hyperpigmentation. Obviously, a solar eviction will be strongly recommended. The risk being maximized with dark phototypes, the choice of the Laser, as well as its specific parameters will be specific and decisive. PMID- 29452657 TI - [Post-inflammatory hyperpigmentation occuring after cosmetic procedures]. AB - A post-inflammatory hyperpigmentation (PIHP) can occur after cosmetic procedures such as chemical peels and lasers. Patients must be informed about this risk. Precautionary measures before, during and after the procedure can prevent or reduce the risk of PIHP. These procedures should not be done in summer on suntanned skin and patients have to be aware of the importance of an effective photoprotection. The PIHP occurs more frequently on dark-skinned patients, in Asians as well as in women with melasma history. In these cases, risk/benefit assessment of the cosmetic procedure is required: no risky procedure in patients at risk! PIHP can also be related to technical errors such as too high concentration or too long exposure time during peel procedure as well as excessive threshold fluences during laser procedure. If many therapies for PIHP damages can be proposed, patients feel frequently that they are not as quickly effective as they would like. Patients must be reassured as many PIHP resolve spontaneously. If photoprotection is always required, it is also possible to accelerate the pigmentation's clearing using the Kligman trio or the numerous topical lightening agents targeting several steps of the hyperpigmentation process. More invasive and expensive therapies such as peels, lasers, IPL or radiofrequency might be used for refractory cases. As a pigmentary relapse might occur after these procedures, the traditional Kligman trio should be always considered.

AB - Mantle cell lymphoma is an aggressive Non-Hodgkin's lymphoma that is considered incurable with standard therapies. Most patients treated with frontline immunochemotherapy relapse within a few years and do not usually respond to salvage chemotherapy. Persistent activation of the B-cell receptor pathway is critical to the pathogenesis of mantle cell lymphoma. Inhibition of Bruton's tyrosine kinase, an essential B-cell receptor pathway component with ibrutinib has shown clinical activity and has changed how MCL is treated in the relapsed/refractory setting. However, resistance to ibrutinib is common and response is limited. Novel agents targeting the B-cell receptor pathway along with therapies outside of the pathway will be reviewed in this article. Ongoing and future studies will better define how these agents should be utilized in the ever-changing treatment landscape of mantle cell lymphoma. PMID- 29452661 TI - Risk stratification in follicular lymphoma. AB - Advances in the understanding of FL biology, molecular characteristics and clinical risk factors are further highlighting the heterogeneity of this disease. Historically used prognostic factors were broadly based on clinical and laboratory features at the time of diagnosis. However novel prognostic factors are emerging that can be studied at the time of diagnosis, and relapse, and use a variety of tools including gene alterations and diagnostic imaging. These novel discoveries are being implemented into daily practice with the ultimate goal of providing a precise, individualized approach to every patient with FL. PMID- 29452662 TI - Pathogenesis of follicular lymphoma. AB - Follicular lymphoma (FL) is presented as a germinal centre B cell lymphoma that is characterized by an indolent clinical course, but remains - paradoxically - largely incurable to date. The last years have seen significant progress in our understanding of FL lymphomagenesis, which is a multi-step process beginning in the bone marrow with the hallmark t(14;18)(q32;q21) translocation. The pathobiology of FL is complex and combines broad somatic changes at the level of both the genome and the epigenome, the latter evidenced by highly recurrent mutations in chromatin-modifying genes such as KMT2D and CREBBP. While the importance of the FL microenvironment has since long been well understood, it has become evident that somatic lesions within tumour cells re-educate normal immune and stromal cells to their advantage. Enhanced understanding of FL pathogenesis is currently leading to refined therapeutic targeting of perturbed biology, paving the way for precision medicine in this lymphoma subtype. PMID- 29452663 TI - Management of untreated advanced stage follicular lymphoma: Role of patient discernment. AB - Follicular lymphoma is the most common indolent non-Hodgkin lymphoma. Advanced stage disease is common at diagnosis. The timing of treatment for follicular lymphoma is best approached by considering the combination of presence or absence of symptoms along with estimation of tumor burden. Upfront treatment strategies should take into initial presentation variables, pace of disease progression and goals of care after discussion with the patient. Treatment approaches remain diverse and patient discernment is paramount. PMID- 29452664 TI - The role of stem cell transplantation in follicular lymphoma. AB - With the introduction of novel treatments paradigms to if or when to use transplantation strategies for patients with follicular lymphoma have changed substantially. Autologous transplantation has been intensively evaluated as consolidation after first induction treatment with positive effects, however the introduction of Rituximab led to comparable improvements and HDT has been moved to relapse treatment. In this indication HDT was frequently use already at first relapse, but now is dominantly used in patients with a highrisk profile, e.g. failure of response, early or multiply relapse and/or signs of transformation. The ideal place for allogeneic transplantation is even harder to define, as the curative potential might be outweighed by the substantial side effect profile and the indication must always be discussed in the light of available alternatives. In consequence, transplantation strategies remain an important therapeutic instrument for patients with FL, however timing within the treatment course has to be defined individually. PMID- 29452665 TI - Novel agents for relapsed and refractory follicular lymphoma. AB - Follicular lymphoma is one of the most common non-Hodgkin's lymphomas. Although current frontline regimens are associated with high response rates, most patients still relapse. When progression is discovered, re-establishing the diagnosis and ruling out transformation in paramount. The outcomes following relapse have been improving due to the activity and increasing availability of novel agents with various mechanisms of action. Despite these advances, single agent activity is limited and the disease remains incurable in the majority of cases. Examples of drug classes with promising activity in relapsed disease include anti-CD20 monoclonal antibodies, immunomodulatory drugs (IMiDs), small molecule tyrosine kinase inhibitors, bcl2 inhibitors, epigenetic modifiers, conjugated antibodies, and checkpoint inhibitors. Many drugs in each class are associated with unique, variable and often surprising toxicity profiles. Combination studies are currently underway with novel-novel combinations and with traditional chemotherapy regimens. This overview will discuss the results of several recent studies exploring activity of novel drugs in relapsed follicular lymphoma. PMID- 29452666 TI - Transformation of follicular lymphoma - Why does it happen and can it be prevented? AB - Follicular lymphoma is a clinical disease with a multitude of presentations and behaviors. Although infrequent, transformation of follicular lymphoma to a more aggressive behaving subtype - prototypically diffuse large B-cell lymphoma - confers a substantially adverse prognosis. There is no consensus for optimal management after transformation is recognized. Historically considered a distinct clinical event, this review highlights the multiple subclinical transformational events that either variably or cumulatively result in clinical recognition of transformed follicular lymphoma. Known and suspected events include genetic and epigenetic perturbations, metabolomic changes, and alterations in the microenvironment. This diverse spectrum of pathways leads to heterogeneous clinical presentations and outcomes of transformed follicular lymphoma. Current options for prevention of transformation are limited to known strategies of managing follicular lymphoma before the transformation is recognized. Although most retrospectively analyzed studies suggest an association of lower transformation rates with early systemic therapy, specific components of therapy such as anti-CD20 antibodies, anthracyclines, or purine analogues are less strongly associated with "preventative' value. Thus, the goal of preventing transformation is of limited value among all factors that go into decisions on early management of follicular lymphoma. Future opportunities to prevent clinical evidence of transformation will benefit from early detection of markers of subclinical transformation and development of therapies to specifically target the biology implied by those markers. PMID- 29452667 TI - Overview on the management of non-gastric MALT lymphomas. AB - Extranodal marginal zone B-cell lymphomas (EMZLs) of the mucosa-associated lymphoid tissue (MALT) are indolent lymphomas which can present at any extranodal site. The most frequent localizations (other than stomach) are ocular adnexa, salivary gland, skin, lung and thyroid. Chronic inflammation and antigenic stimulation are a potential risk for the development of MALT lymphomas. While Helicobacter Pylori (HP) is known to be associated with gastric MALT lymphoma and antibiotic therapy is effective in the setting of HP-positive, other microorganisms (such as Chlamydophila Psittaci, Campylobacter Jejiuni, Borrelia Burgdoferi) have been implicated in the pathogenesis of non-gastric MALT lymphomas. However, antibiotic therapy has not been extensively investigated for the non-gastric type, except for ocular adnexal MALT lymphoma, which could benefit from an upfront treatment with doxycycline. Surgery, radiotherapy, Rituximab alone or in combination with chemotherapy and "chemo-free" approaches, including lenalidomide, have shown efficacy in the treatment of non-gastric MALT lymphomas. PMID- 29452668 TI - Should rituximab replace splenectomy in the management of splenic marginal zone lymphoma? AB - BACKGROUND: SMZL is a relatively rare low grade B-cell lymphoma, characterized usually by an indolent clinical behavior. Since there is no prospective randomized trials to establish the best treatment approach, decision on therapeutic management should be based on the available retrospective series. Based on these data, rituximab and splenectomy appear to be the most effective. Splenectomy represented the standard treatment modality until early 2000s. More than 90% of the patients present quick amelioration of splenomegaly related symptoms along with improvement of cytopenias related to hypersplenism. The median progression free survival was 8.25 years in the largest series of patients published so far, while the median 5- and 10- year OS were 84% and 67%, respectively. Responses to splenectomy are not complete since extrasplenic disease persists. Patients with heavy bone marrow infiltration, lymphadenopathy or other disease localization besides the spleen are not good candidates for splenectomy. Furthermore splenectomy is a major surgical procedure accompanied by acute perioperative complications as well as late toxicities mainly due to infections. For that reasons splenectomy is not appropriate for elderly patients or patients with comorbidities with a high surgical risk. On the other hand rituximab monotherapy displays high efficacy with minimal toxicity. Several published series have shown an ORR more than 90%, with high CR rates (~50%). The 10-year PFS and OS were 63% and 85%, respectively in a series of 104 SMZL patients. The role of rituximab maintenance has been investigated by only one group. Based on these data, maintenance with rituximab further improved the quality of responses by increasing significantly the CR rates (from 42% at the end of induction to 71% at the end of maintenance treatment), as well as the duration of responses: 7-year PFS was 75% for those patients who received maintenance vs 39% for those who did not (p < 0.0004). However no difference in OS has been noticed between the two groups, so far. Summarizing the above data, it is obvious that Rituximab monotherapy is associated with high response rates, long response duration and favorable safety profile, rendering it as the treatment of choice in SMZL. PMID- 29452669 TI - Optimal management of the young patient CLL patient. AB - The emergence of targeted therapy for patients with chronic lymphocytic leukemia (CLL) has permanently altered the therapeutic landscape. In both upfront and relapsed settings, safe and effective oral kinase inhibitors are available which rival the responses and durability seen with standard chemo immunotherapy regimens. In 2016, ibrutinib was granted Federal Drug Administration approval for first-line therapy in patients with CLL. While its role as initial therapy for older, unfit or deleted 17p CLL patients is less controversial, its role as first line treatment for younger fit patients is less clear, begging the question, what is the optimal treatment for these patients, novel agents or standard CIT strategies? In this review, we aim to provide guidance for what we believe is the optimal management of young fit patients with CLL. PMID- 29452670 TI - What is the optimal management of older CLL patients? AB - CLL is the most common leukemia in older adults with a median age at diagnosis of 71. Therefore, management of patients with this disease must take into account the older age of most patients and consequences of this in terms of functional status and organ function. This review will discuss the management of CLL with regards to observation prior to the initiation of therapy, functional status, and initial treatment. We will discuss criteria for the initiation of therapy, and how initial therapy is different between older and younger patients. Finally, we will discuss specific therapies including chemoimmunotherapy and newer targeted therapies that are being used widely in the older patient population. PMID- 29452671 TI - What is the optimal initial management of the younger mantle cell lymphoma patient? AB - The last 20 years has seen considerable advances made in the management of younger patients with mantle cell lymphoma. The use of high dose cytarabine and rituximab in induction therapy, usually followed by autologous stem cell transplant consolidation, has become established practice and the median overall survival now exceeds 10 years. However, this high intensity upfront approach is not necessarily appropriate for all newly diagnosed patients. A minority exhibit disease that behaves in an indolent fashion with no proven benefit from early intervention, and at the opposite end of the spectrum a high-risk group exists who do poorly with conventional treatment. This review considers the role of watch and wait strategies in indolent presentations, examines the evidence behind current induction approaches and considers ways to modify these for those young patients presenting with adverse features. It concludes with an assessment of the emerging role of novel agents and the search for robust risk-adapted treatment strategies. PMID- 29452672 TI - What is the optimal initial management of the older MCL patient? AB - The current first line treatment of a patient with mantle cell lymphoma (MCL) is often considered as too toxic for elderly patients. The elderly, however, comprise the majority of the patients with MCL. The results of several recent studies have shown that the outcome of this patient group is not as dismal as in the past. Indeed, if patients are not considered frail, and can tolerate rituximab and moderate intensive chemotherapy such as R-CHOP followed by rituximab maintenance or R-bendamustine, a 4-year overall survival of >80% can be achieved. In this chapter the developments of the regimens, resulting in the standard treatment options for these patients, are discussed. PMID- 29452673 TI - Clearing the haze around medicinal cannabis.

PMID- 29452684 TI - Evaluation of the safety, tolerability, and efficacy of pimavanserin versus placebo in patients with Alzheimer's disease psychosis: a phase 2, randomised, placebo-controlled, double-blind study. AB - BACKGROUND: Pimavanserin is a selective 5-HT2A receptor inverse agonist and antagonist approved in the USA for the treatment of hallucinations and delusions associated with Parkinson's disease psychosis. No safe or effective pharmacological treatment is approved for psychosis in patients with Alzheimer's disease. Therefore, we aimed to evaluate the safety, tolerability, and efficacy of pimavanserin versus placebo in patients with Alzheimer's disease psychosis. METHODS: We did a phase 2, randomised, double-blind, placebo-controlled, single centre (with multiple affiliated nursing home sites across the UK) study. We included participants of either sex who were aged 50 years or older with possible or probable Alzheimer's disease and psychotic symptoms including visual or auditory hallucinations, delusions, or both. Participants were randomly assigned (1:1) to 12 weeks of oral treatment with either pimavanserin (two 17 mg tablets daily) or placebo, with use of permuted block sizes of four and stratified by baseline Mini-Mental State Examination (MMSE) total score (<6 or >=6) and Neuropsychiatric Inventory-Nursing Home version (NPI-NH) psychosis score (<12 or >=12). Participants, caregivers, the study sponsor, and study personnel at the clinic site were masked to treatment assignment. The primary endpoint was mean change from baseline to week 6 in the NPI-NH psychosis score for pimavanserin versus placebo in the modified intention-to-treat population. Sustained benefit and safety of pimavanserin were assessed through week 12. This study is registered at ClinicalTrials.gov, number NCT02035553. FINDINGS: Between Jan 16, 2014, and Oct 27, 2016, 345 participants across 133 nursing homes were screened, of whom 181 were randomly assigned treatment (n=90 pimavanserin and n=91 placebo). 178 participants were included in the modified intention-to-treat population. Mean total baseline NPI-NH psychosis scores were 9.5 (SD 4.8) for the pimavanserin group and 10.0 (5.6) for the placebo group. Mean change in the NPI NH psychosis score at week 6 was -3.76 points (SE 0.65) for pimavanserin and 1.93 points (0.63) for placebo (mean difference -1.84 [95% CI -3.64 to -0.04], Cohen's d=-0.32; p=0.045). By week 12, no significant advantage for pimavanserin versus placebo was observed for the overall study population (treatment difference -0.51 [95% CI -2.23 to 1.21]; p=0.561). Common adverse events were falls (21 [23%] of 90 participants in the pimavanserin group vs 21 [23%] of 91 in the placebo group), urinary tract infections (20 [22%] vs 25 [28%]), and agitation (19 [21%] vs 13 [14%]). Eight (9%) participants on pimavanserin and 11 (12%) on placebo discontinued treatment because of adverse events. No detrimental effect was observed on cognition or motor function in either group. INTERPRETATION: Pimavanserin showed efficacy in patients with Alzheimer's disease psychosis at the primary endpoint (week 6) with an acceptable tolerability profile and without negative effect on cognition. Further follow-up to week 12 did not show significant advantage for pimavanserin versus placebo. FUNDING: ACADIA Pharmaceuticals. PMID- 29452686 TI - Technological advances and changing indications for lumbar puncture in neurological disorders. AB - Technological advances have changed the indications for and the way in which lumbar puncture is done. Suspected CNS infection remains the most common indication for lumbar puncture, but new molecular techniques have broadened CSF analysis indications, such as the determination of neuronal autoantibodies in autoimmune encephalitis. New screening techniques have increased sensitvity for pathogen detection and can be used to identify pathogens that were previously unknown to cause CNS infections. Evidence suggests that potential treatments for neurodegenerative diseases, such as Alzheimer's disease, will rely on early detection of the disease with the use of CSF biomarkers. In addition to being used as a diagnostic tool, lumbar puncture can also be used to administer intrathecal treatments as shown by studies of antisense oligonucleotides in patients with spinal muscular atrophy. Lumbar puncture is generally a safe procedure but complications can occur, ranging from minor (eg, back pain) to potentially devastating (eg, cerebral herniation). Evidence that an atraumatic needle tip design reduces complications of lumbar puncture is compelling, and reinforces the need to change clinical practice. PMID- 29452687 TI - Diagnostic challenges in epilepsy: seizure under-reporting and seizure detection. AB - Epileptic seizures vary greatly in clinical phenomenology and can markedly affect the patient's quality of life. As therapeutic interventions focus on reduction or elimination of seizures, the accurate documentation of seizure occurrence is essential. However, patient self-evaluation compared with objective evaluation by video-electroencephalography (EEG) monitoring or long-term ambulatory EEG revealed that patients document fewer than 50% of their seizures, on average, and that documentation accuracy varies significantly over time. For good clinical practice in epilepsy, novel and feasible seizure detection techniques for ambulatory long-term use are needed. Generalised tonic-clonic seizures can already be detected reliably by methods that rely on motion recording (eg, surface electromyography). However, the automatic detection of other seizure types, such as complex partial seizures, will require multimodal approaches that combine the measurement of ictal autonomic alterations (eg, heart rate) and of characteristic movement patterns (eg, accelerometry). Innovative and feasible tools for automatic seizure detection are likely to advance both monitoring of the outcome of a treatment in a patient and clinical research in epilepsy. PMID- 29452685 TI - Behavioural outcomes of subthalamic stimulation and medical therapy versus medical therapy alone for Parkinson's disease with early motor complications (EARLYSTIM trial): secondary analysis of an open-label randomised trial. AB - BACKGROUND: Although subthalamic stimulation is a recognised treatment for motor complications in Parkinson's disease, reports on behavioural outcomes are controversial, which represents a major challenge when counselling candidates for subthalamic stimulation. We aimed to assess changes in behaviour in patients with Parkinson's disease receiving combined treatment with subthalamic stimulation and medical therapy over a 2-year follow-up period as compared with the behavioural evolution under medical therapy alone. METHODS: We did a parallel, open-label study (EARLYSTIM) at 17 surgical centres in France (n=8) and Germany (n=9). We recruited patients with Parkinson's disease who were disabled by early motor complications. Participants were randomly allocated (1:1) to either medical therapy alone or bilateral subthalamic stimulation plus medical therapy. The primary outcome was mean change in quality of life from baseline to 2 years. A secondary analysis was also done to assess behavioural outcomes. We used the Ardouin Scale of Behavior in Parkinson's Disease to assess changes in behaviour between baseline and 2-year follow-up. Apathy was also measured using the Starkstein Apathy Scale, and depression was assessed with the Beck Depression Inventory. The secondary analysis was done in all patients recruited. We used a generalised estimating equations (GEE) regression model for individual items and mixed model regression for subscores of the Ardouin scale and the apathy and depression scales. This trial is registered with ClinicalTrials.gov, number NCT00354133. The primary analysis has been reported elsewhere; this report presents the secondary analysis only. FINDINGS: Between July, 2006, and November, 2009, 251 participants were recruited, of whom 127 were allocated medical therapy alone and 124 were assigned bilateral subthalamic stimulation plus medical therapy. At 2-year follow-up, the levodopa-equivalent dose was reduced by 39% ( 363.3 mg/day [SE 41.8]) in individuals allocated bilateral subthalamic stimulation plus medical therapy and was increased by 21% (245.8 mg/day [40.4]) in those assigned medical therapy alone (p<0.0001). Neuropsychiatric fluctuations decreased with bilateral subthalamic stimulation plus medical therapy during 2 year follow-up (mean change -0.65 points [SE 0.15]) and did not change with medical therapy alone (-0.02 points [0.15]); the between-group difference in change from baseline was significant (p=0.0028). At 2 years, the Ardouin scale subscore for hyperdopaminergic behavioural disorders had decreased with bilateral subthalamic stimulation plus medical therapy (mean change -1.26 points [SE 0.35]) and had increased with medical therapy alone (1.12 points [0.35]); the between group difference was significant (p<0.0001). Mean change from baseline at 2 years in the Ardouin scale subscore for hypodopaminergic behavioural disorders, the Starkstein Apathy Scale score, and the Beck Depression Inventory score did not differ between treatment groups. Antidepressants were stopped in 12 patients assigned bilateral subthalamic stimulation plus medical therapy versus four patients allocated medical therapy alone. Neuroleptics were started in nine patients assigned medical therapy alone versus one patient allocated bilateral subthalamic stimulation plus medical therapy. During the 2-year follow-up, two individuals assigned bilateral subthalamic stimulation plus medical therapy and one patient allocated medical therapy alone died by suicide. INTERPRETATION: In a large cohort with Parkinson's disease and early motor complications, better overall behavioural outcomes were noted with bilateral subthalamic stimulation plus medical therapy compared with medical therapy alone. The presence of hyperdopaminergic behaviours and neuropsychiatric fluctuations can be judged additional arguments in favour of subthalamic stimulation if surgery is considered for disabling motor complications.

PMID- 29452688 TI - Comparison of the Efficacy and Safety of Orbital and Rotational Atherectomy in Calcified Narrowings in Patients Who Underwent Percutaneous Coronary Intervention. AB - We aimed to compare the safety and efficacy of rotational atherectomy (RA) and orbital atherectomy (OA) during percutaneous coronary intervention in an all comer population with severely calcified lesions. We included all patients who underwent percutaneous coronary intervention with OA or RA in our institution from October 2013 until October 2016. Comparison of baseline and procedural characteristics, along with acute complication rates and postprocedural cardiac enzyme elevation, was performed. There were 191 RA and 57 OA patients. Other than creatinine clearance, which was lower in patients with OA (p = 0.01), there were no differences in baseline characteristics. OA was more frequent in left anterior descending artery lesions (p = 0.02), whereas RA was more common in right coronary artery lesions (p = 0.01). Intracoronary imaging rates were above 60% in both groups. There was a higher rate of coronary dissections with OA compared with RA (p = 0.003), but there was no difference in periprocedural events. Maximal troponin levels were similar in both groups. Residual stenosis measured by intravascular ultrasound in 29 patients revealed no significant differences between OA and RA (p = 0.58). In conclusion, RA and OA have similar safety and efficacy profiles in treating patients with calcified coronary lesions, and intracoronary imaging is highly beneficial in identifying coronary injury after atherectomy procedures. PMID- 29452689 TI - Measurements of Lumen Areas and Diameters of Proximal and Middle Coronary Artery Segments in Subjects Without Coronary Atherosclerosis. AB - There are plenty of data on morphology and lumen dimensions of diseased coronary arteries. However, information on normal coronary vessel anatomy is scarce. We provided computed tomography angiography-derived reference values of lumen dimensions in proximal and middle coronary segments in a healthy population with respect to gender and vessel dominance. Consecutive 2,849 computed tomography angiography examinations were reviewed to identify 201 subjects (77 men, patient age 50 +/- 13 years) whose coronary arteries were free from any sign of atherosclerosis (calcium score 0, no detectable plaque). For all proximal and middle coronary segments, lumen areas (LAs) and lumen diameters were measured. Coronary vessel segmentation and dominance pattern were defined using the Syntax Score. Normal values of LAs and lumen diameters were significantly smaller for women compared with men except for the proximal right coronary artery and the left main coronary artery (LMCA) (20.2 +/- 6.6 mm2 vs 23.0 +/- 6.1 mm2, p = 0.0003, and 5.0 +/- 0.8 mm vs 5.4 +/- 0.7 mm, p = 0.0001). The lower limit of normal for the LMCA (defined as mean LA - 2 standard deviations) equaled 7.0 and 10.8 mm2 for women and men, respectively. Subjects with left (vs right) coronary dominance had significantly larger areas and diameters of the LMCA (26.2 +/- 9.2 mm2 vs 20.7 +/- 6.0 mm2, p = 0.0017, and 5.7 +/- 1.0 mm vs 5.1 +/- 0.7 mm, p = 0.0017, respectively) and proximal left circumflex (13.8 +/- 2.7 mm2 vs 10.4 +/- 3.8 mm2, p = 0.0001, and 4.2 +/- 0.4 mm vs 3.6 +/- 0.7 mm, p = 0.0001, respectively) and smaller areas and diameters of the proximal right coronary artery (7.1 +/- 2.0 mm2 vs 13.3 +/- 3.6 mm2, p <0.0001, and 3.0 +/- 0.4 mm vs 4.1 +/- 0.6 mm, p <0.0001, respectively). In conclusion, gender and coronary artery dominance pattern significantly impact normal LAs and dimensions in subjects without coronary atherosclerosis. PMID- 29452690 TI - Utility of Physician Selection of Cardiac Tests in a Chest Pain Unit to Exclude Acute Coronary Syndrome Among Patients Without a History of Coronary Artery Disease. AB - There are few data on the utility of physician selection of cardiac tests, including no-test, in a chest pain unit (CPU) to rule out acute coronary syndrome in low-risk patients without a history of coronary artery disease. We analyzed consecutive low-risk patients admitted to our CPU between 2012 and 2014 and determined the proportion of patients selected for testing, the type of initial cardiac test selected, and the incidence of major adverse cardiac events (MACEs) at 30 days and 6 months. The study group comprised 619 patients: mean age 57 years (27 to 92), 332 women (54%), and 360 (58%) with multiple cardiac risk factors. Cardiac testing included 283 no-test (46%); 179 exercise treadmill (29%); 113 myocardial perfusion stress scintigraphy (18%); <10% each for exercise stress echocardiography and coronary angiography. Testing was negative in 296 (88%), nondiagnostic in 30 (9%), and positive in 10 patients (3%). There were no MACEs at 30 days in any patients, and at 6 months, MACEs were 5 (1.1%). Length of stay was less in no-test than in tested patients (5.4 hours vs 9.8 hours, p <0.0001), and there was no difference in incidence of MACE at 6 months in no-test vs tested patients (2 MACEs vs 3 MACEs). Physician selection of cardiac tests, including no-test, promptly identified patients at low risk of acute coronary syndrome who could be safely and rapidly discharged from the CPU. Exclusion of cardiac testing shortened length of stay and was not associated with increase in MACE at 6 months. PMID- 29452691 TI - Recurrent Cardiovascular Events in Survivors of Myocardial Infarction With ST Segment Elevation (from the AMI-QUEBEC Study). AB - The characteristics and predictors of long-term recurrent ischemic cardiovascular events (RICEs) after myocardial infarction with ST-segment elevation (STEMI) have not yet been clarified. We aimed to characterize the 10-year incidence, types, and predictors of RICE. We obtained 10-year follow-up of STEMI survivors at 17 Quebec hospitals in Canada (the AMI-QUEBEC Study) in 2003. There were 858 patients; mean age was 60 years and 73% were male. The majority of patients receive reperfusion therapy; 53.3% and 39.2% of patients received primary percutaneous coronary intervention (PCI) and fibrinolytic therapy, respectively. Seventy-five percent of patients underwent in-hospital PCI (elective, rescue, and primary). At 10 years, 42% of patients suffered a RICE, with most RICEs (88%) caused by recurrent cardiac ischemia. The risk of RICE was the highest during the first year (23.5 per patient-year). At 10 years, the all-cause mortality was 19.3%, with 1/3 of deaths being RICE-related. Previous cardiovascular event, heart failure during the index STEMI hospitalization, discharge prescription of calcium blocker increased the risk of RICE by almost twofold. Each point increase in TIMI (Thrombolysis In Myocardial Infarction) score augmented the risk of RICE by 6%, whereas discharge prescription of dual antiplatelets reduced the risk of RICE by 23%. Our findings suggested that survivors of STEMI remain at high long term risk of RICE despite high rate of reperfusion therapy and in-hospital PCI. Patients with previous cardiovascular event, in-hospital heart failure, and high TIMI score were particularly susceptible to RICE. Future studies are needed to confirm the impacts of calcium blocker and dual antiplatelets on long-term risk of RICE. PMID- 29452692 TI - Prognostic Significance of Complex Ventricular Arrhythmias Complicating ST Segment Elevation Myocardial Infarction. AB - The aim of the study was to assess the clinical significance of complex ventricular arrhythmias (VAs) (sustained ventricular tachycardia [sVT] and ventricular fibrillation [VF]) in patients with ST-segment elevation myocardial infarction (STEMI) depending on timing of arrhythmia. We analyzed 4,363 consecutive patients with STEMI treated invasively between 2004 and 2014. The median follow-up was 69.6 months (range: 0 to 139.8 months). The study population was divided into 2 main groups; VA group encompassed 476 patients (10.91%) with VAs, whereas 3,887 subjects (89.09%) without VT or VF were included into the control group. In VA population, prereperfusion VA (34.24%; n = 163) was the most common arrhythmia, whereas reperfusion-induced, early postreperfusion, and late postreperfusion VAs were diagnosed in 103 (21.64%), 103 (21.64%), and 107 (22.48%) patients, respectively. Every type of sVT or VF complicating STEMI portended significantly worse in-hospital prognosis, however a late onset arrhythmia was associated with the highest (over fivefold) and reperfusion induced VA with the lowest (less than threefold) increase in mortality risk compared with the control group. On the contrary, long-term mortality was significantly increased only in subjects with late postreperfusion and prereperfusion VAs compared with VA-free population (43.93% and 36.81%, respectively vs 22.58%; p <0.001). Apart from cardiogenic shock on admission, late postreperfusion (hazard ratio 3.39) and prereperfusion VAs (hazard ratio 2.76) were the strongest independent predictors of death in the analyzed population. In conclusion, 1 in 10 patients with STEMI treated invasively was affected by sVT or VF. The clinical impact of VAs was strongly dependent on timing of arrhythmia.

PMID- 29452694 TI - Chitinase 3 like 1 (CHI3L1) promotes vasculogenic mimicry formation in cervical cancer. AB - Vasculogenic mimicry (VM) is an alternative microvascular system which tumour cells orchestrate, independent of endothelial cell-mediated angiogenesis. VM develops tumour vascular networks that correlate with tumour growth, metastasis, and short survival time of patients with a number of cancers. However, little is known regarding VM in the vascularisation of cervical cancer. Chitinase 3 like 1 (CHI3L1) has been previously reported to display the ability to induce angiogenesis in cervical cancer. Here, we explored a pathological role of CHI3L1 in tumour cell-mediated vascularisation. Sixty-six samples of cervical cancer were collected to examine CHI3L1 expression and VM formation using immunohistochemistry and CD34-periodic acid-Schiff (PAS) dual staining. CHI3L1 expression was significantly correlated with formation of tumour cell-associated vascular channels in the absence of endothelial cells (p=0.031). Interestingly, tumour samples lacking VM were positively correlated with non-metastasis (p=0.035). Patients with VM positive tumours tended to have decreased overall survival (OS) compared to those with VM negative samples (43.9 versus 64.6 months, p=0.079). In addition, recombinant CHI3L1 enhanced cervical cancer cell lines to form tube-like structures, supporting the notion that CHI3L1 mediates VM in cervical cancer. Our present data reveal the crucial role of CHI3L1 in the formation of VM, which may contribute to tumour aggressiveness. Therefore, targeting CHI3L1 may be a valuable strategy for the reduction of cervical cancer vascularisation and metastasis. PMID- 29452695 TI - The combination of maltose-binding protein and BCG-induced Th1 activation is involved in TLR2/9-mediated upregulation of MyD88-TRAF6 and TLR4-mediated downregulation of TRIF-TRAF3. AB - Our previous study demonstrated that maltose-binding protein (MBP) activated Th1 through the TLR2-mediated MyD88-dependent pathway and the TLR4-mediated TRIF dependent pathway. The combination of MBP and BCG synergistically induced Th1 activation, and the TLR2/9-mediated MyD88-dependent pathway is involved in this process. To further explore this mechanism, we stimulated purified mouse CD4+ T cells with MBP and BCG in vitro. The results demonstrated that MBP combined with BCG synergistically increased IFN-gamma production and TLR2/4/9 expression, suggesting the involvement of TLR2/4/9 in the combination-induced Th1 activation. Next, TLRs 2/4/9 were blocked to analyze the effects of TLRs on Th1 activation. The results demonstrated that MBP induced a low level of Th1 activation by upregulating TLR2-mediated MyD88-TRAF6 and TLR4-mediated TRIF-TRAF3 expression, whereas MBP combined with BCG induced synergistic Th1 activation, which was not only triggered by strong upregulation of TLR2/9-mediated MyD88-TRAF6 expression but also by shifting TLR4-mediated TRIF-TRAF3 into the TRIF-TRAF6 pathway. Moreover, we observed that a TLR4 antibody upregulated MyD88 expression and a TLR9 inhibitor downregulated TRIF expression, indicating that there was cross talk between TLRs 2/4/9 in MBP combined with BCG-induced Th1 activation. Our findings may expand the knowledge regarding TLR cross-talk involved in regulating the Th1 response. PMID- 29452696 TI - Embarrassed and Sorry. PMID- 29452697 TI - President's Message. PMID- 29452698 TI - Are cleavage anomalies, multinucleation, or specific cell cycle kinetics observed with time-lapse imaging predictive of embryo developmental capacity or ploidy? AB - OBJECTIVE: To determine whether cleavage anomalies, multinucleation, and specific cellular kinetic parameters available from time-lapse imaging are predictive of developmental capacity or blastocyst chromosomal status. DESIGN: Retrospective analysis of prospectively collected data. SETTING: Single academic center. PATIENT(S): A total of 1,478 zygotes from patients with blastocysts biopsied for preimplantation genetic screening were cultured in the EmbryoScope. INTERVENTION(S): Trophectoderm biopsy. MAIN OUTCOME MEASURE(S): Embryo dysmorphisms, developmental kinetics, and euploidy. RESULT(S): Of the 767 biopsied blastocysts, 41.6% (95% confidence interval [CI], 38%-45%) were diagnosed as euploid. Individual dysmorphisms such as multinucleation, reverse cleavage, irregular chaotic division, or direct uneven cleavage were not associated with aneuploidy. Direct uneven cleavage and irregular chaotic division embryos did, however, exhibit lower developmental potential. The presence of two or more dysmorphisms was associated with an overall lower euploidy rate, 27.6% (95% CI 19%-39%). Early embryo kinetics were predictive of blastocyst development but not ploidy status. In contrast, chromosomal status correlated significantly with start time of blastulation (tSB), expansion (tEB), and the tEB-tSB interval. A lower euploidy rate, 36.6% (95% CI 33%-42%) was observed with tSB >= 96.2 hours, compared with 48.2% with tSB < 96.2 (95% CI 42%-54%). A drop in euploidy rate to 30% (95% CI 25%-37%) was observed in blastocysts with delayed expansion (tEB > 116). The proportion of euploid blastocysts was increased with tEB-tSB intervals of <=13 hours. A logistic regression model to enhance the probability of selecting a euploid blastocyst was constructed. CONCLUSION(S): Morphokinetics may aid in selection of euploid embryos from a cohort of day 5/6 blastocysts.

AB - Hyperlipidemia is a systemic disease caused by abnormal human lipid metabolism. Dietary control and treatment on hyperlipidemia is now a popular therapy pathway. This paper focuses on the medicine food homology (MFH) species used in China with hypolipidemic function, and emphasizes on the active ingredients and their pharmacological effect. The single herbal and its hypolipidemic active ingredients are summarized through reviewing the relevant literatures published in the past twenty years. The ingredients are divided into polysaccharides, flavonoids, steroidal saponins, quinones, alkaloids and others, of which the related researches are described from the aspects of sources, model and method, result and mechanisms, respectively. MFH exerts treating hyperlipidemia through inhibiting the biosynthesis of endogenous lipids, promoting the catabolism of exogenous lipid, restraining lipid absorption, and anti-lipid peroxidation. It is concluded that some MFH species with low toxicity and small side effects can used to adjust the diet nutrition to prevent the occurrence of hyperlipidemia and cardiovascular disease. PMID- 29452700 TI - Liver resection for recurrent hepatocellular carcinoma to improve survivability: a proposal of indication criteria. AB - BACKGROUND: Despite curative resection of hepatocellular carcinoma, patients have a high probability of recurrence. We examined indications for liver resection in cases of recurrent hepatocellular carcinoma. METHODS: Patients undergoing a second liver resection (n=210) or treatment by transcatheter arterial chemoembolization (n=184) for recurrent hepatocellular carcinoma of up to 3 lesions were included. We developed a prediction score based on prognostic factors and compared survival according to this prediction score. RESULTS: The prediction score was based on 3 independent variables identified by survival analysis in 210 patients undergoing a second liver resection and included age >= 75 years, tumor size >= 3.0 cm, and multiple tumors. Each patient was assigned a total score. Median overall survival in patients undergoing a second liver resection with scores of 0, 1, and 2/3 were 7.9 years (95% confidence interval, 5.6-NA), 4.5 years (3.8-6.2), and 2.6 years (2.1-5.3), respectively (P < 0.001). Among patients with a score of 0, the survival in patients undergoing liver resection was greater than survival in those undergoing transcatheter arterial chemoembolization (median 7.9 [95% confidence interval, 5.6-NA] years versus 3.1 [2.1-3.7] years, P < 0.001), and resection was an independent factor for survival. In contrast, survival did not differ in patients with scores 2/3 (2.6 years [95% confidence interval, 1.9-5.3] versus 2.3 years [1.6-2.8], P = 0.176). CONCLUSION: Liver resection is recommended as first-line therapy for recurrent hepatocellular carcinoma in patients with a score of 0, while those with score 2/3 should be considered candidates for transcatheter arterial chemoembolization.

PMID- 29452702 TI - The value proposition of simulation-based education. AB - Simulation has become an integral part of physician education, and abundant evidence confirms that simulation-based education improves learners' skills and behaviors and is associated with improved patient outcomes. The resources required to implement simulation-based education, however, have led some stakeholders to question the overall value proposition of simulation-based education. This paper summarizes the information from a special panel on this topic and defines research priorities for the field. Future work should focus on both outcomes and costs, with robust measurement of resource investments, provider performance (in both simulation and real settings), patient outcomes, and impact on the health care organization. Increased attention to training practicing clinicians and health care teams is also essential. Clarifying the value proposition of simulation-based education will require a major national effort with funding from multiple sponsors and active engagement of a variety of stakeholders. PMID- 29452703 TI - Validation of the eighth edition of the American Joint Committee on Cancer staging system for ampulla of Vater cancer. AB - BACKGROUND: The American Joint Committee on Cancer recently proposed the eighth edition of cancer staging system. Validation studies are required to evaluate the prognostic stratification of ampulla of Vater cancer patients. METHODS: In the study, 369 operatively resected patients with ampullary cancers were grouped based on the eighth T (T1a, limited to sphincter of Oddi; T1b, invasion to duodenal submucosa; T2, invasion to duodenal proper muscle; T3a, invasion to pancreas <=0.5 cm; T3b, invasion to pancreas >0.5 cm; and T4, involvement of celiac axis or superior mesenteric artery) and N (N0, no nodal metastasis; N1, 1 3 nodal metastasis; and N2, >=4 nodal metastasis) category of ampullary cancer staging. RESULTS: Overall 5-year survival rates for T and N categories were as followed: T1a, 83%; T1b, 71%; T2, 46%; T3a, 48%; T3b, 28.5%, T4, 7% (P< .001); N0, 44.8%; N1, 20%; N2, 4% (P < .001). Pair-wise comparisons demonstrated significant differences between T1a-b (P = .005), T3a-T3b (P = .03), N0-N1 (P < .001), and N1-N2 (P = .007) tumors, but not between T1b-T2 (P = .20), T2-T3a (P = .84), and T3b-T4 (P = .17) lesions. CONCLUSION: The eighth edition T category for ampullary cancer does not stratify patients accurately with regard to prognosis. Modification of the current T category with eliminating subcategories (T1, invasion to duodenal submucosa; T2, invasion to duodenal proper muscle; T3, invasion to pancreas or duodenal subserosa) is a better way for determining prognosis of ampullary cancer. The current N category segregates patient survival well. PMID- 29452704 TI - Substance Use Disorder Among Current Cancer Patients: Rates and Correlates Nationally in the Department of Veterans Affairs. AB - BACKGROUND: Substance use disorders (SUDs) are known to cause or complicate treatment of many types of cancers. OBJECTIVES: We sought to systematically assess rates of current SUDs among patients currently in treatment for cancer. METHODS: The National Veteran Health Administration administrative data from fiscal year 2012 were used to compare veterans with both cancer and comorbid SUDs to veterans with cancer but no SUDs and those with a SUD but no cancer. Bivariate comparisons and multivariate logistic regression were used to compare groups on sociodemographic characteristics, medical and mental health diagnoses, service use, and psychotropic and opioid medication fills. RESULTS: Of 482,688 veterans with cancer diagnoses, 32,037 (6.64%) had a comorbid SUD diagnosis. Veterans with cancer and a SUD had more medical and psychiatric disorders than those with cancer alone, a greater risk of homelessness, and a greater use of both mental and medical health services, with 60% receiving mental health outpatient treatment. These veterans had fewer differences from veterans with SUDs only, although they were older and had more medical illnesses. Notably the cancer SUD group had higher rates of hepatic disease and received a greater number of opioid prescriptions than both veterans with cancer alone and veterans with SUD alone. CONCLUSIONS: Veterans with cancer and SUD showed a specific risk for liver disease and a higher use of opioids. Collaborative teams involving oncology, palliative care, and psychiatry may be best able to address the challenge of providing adequate and safe opiate pain control for this vulnerable population.

AB - OBJECTIVE: To evaluate trends in the incidence of kidney stones and characteristics associated with changes in the incidence rate over 3 decades. PATIENTS AND METHODS: Adult stone formers in Olmsted County, Minnesota, from January 1, 1984, to December 31, 2012, were validated and characterized by age, sex, stone composition, and imaging modality. The incidence of kidney stones per 100,000 person-years was estimated. Characteristics associated with changes in the incidence rate over time were assessed using Poisson regression models. RESULTS: There were 3224 confirmed symptomatic (stone seen), 606 suspected symptomatic (no stone seen), and 617 incidental asymptomatic kidney stone formers. The incidence of confirmed symptomatic kidney stones increased from the year 1984 to 2012 in both men (145 to 299/100,000 person-years; incidence rate ratio per 5 years, 1.14, P<.001) and women (51 to 217/100,000 person-years; incidence rate ratio per 5 years, 1.29, P<.001). Overall, the incidence of suspected symptomatic kidney stones did not change, but that of asymptomatic kidney stones increased. Utilization of computed tomography for confirmed symptomatic stones increased from 1.8% in 1984 to 77% in 2012; there was a corresponding higher increased incidence of symptomatic small stones (<=3 mm) than of larger stones (>3 mm). Confirmed symptomatic kidney stones with documented spontaneous passage also increased. The incidence of kidney stones with unknown composition increased more than that of stones with known composition. CONCLUSION: The incidence of both symptomatic and asymptomatic kidney stones has increased dramatically. The increased utilization of computed tomography during this period may have improved stone detection and contributed to the increased kidney stone incidence.

AB - Primary sclerosing cholangitis is a rare, chronic cholestatic liver disease characterised by intrahepatic or extrahepatic stricturing, or both, with bile duct fibrosis. Inflammation and fibrosis of bile ducts and the liver are followed by impaired bile formation or flow and progressive liver dysfunction. Patients might be asymptomatic at presentation or might have pruritus, fatigue, right upper quadrant pain, recurrent cholangitis, or sequelae of portal hypertension. The key diagnostic elements are cholestatic liver biochemistry and bile duct stricturing on cholangiography. Genetic and environmental factors are important in the cause of the disease, with the intestinal microbiome increasingly thought to play a pathogenetic role. Approximately 70% of patients have concurrent inflammatory bowel disease and patients require colonoscopic screening and surveillance. Primary sclerosing cholangitis is associated with increased malignancy risk and surveillance strategies for early cholangiocarcinoma detection are limited. No single drug has been proven to improve transplant-free survival. Liver transplantation is effective for advanced disease but at least 25% of patients develop recurrent disease in the graft.

AB - This paper presents a detailed study on the indoor air pollution in the Jokahng Temple at Tibet Plateau, and its implication to human health. The mean concentrations of PM1.0 and PM2.5 were 435.0 +/- 309.5 and 483.0 +/- 284.9 MUg/m3, respectively. The PM2.5 concentration exceeded the National Ambient Air Quality Standard (75 MUg/m3) by 6.4 times. The size-segregated aerosols displayed a bimodal distribution. One peak was observed in the fine mode (0.4-2.1 MUm) and the other peak appeared in the coarse mode (2.1-9.0 MUm). The concentration of the total size-resolved PM was 794.3 +/- 84.9 MUg/m3. The mass fraction of coarse particles shared by 41.1%, apparently higher than that reported at low altitudes, probably due to incomplete combustion at Tibet Plateau with hypoxic atmospheric environment. The total concentration of polycyclic aromatic hydrocarbons (PAHs) was 331.2 +/- 60.3 ng/m3, in which the concentration of benzo(a)pyrene (BaP) was 18.5 +/- 4.3 ng/m3, over ten times higher than the maximum permissible risk value of 1 ng/m3 on account of carcinogenic potency of particulate PAHs through inhalation. PAHs exhibited a trimodal distribution, of which two peaks were observed in the fine mode and one peak in the coarse mode. With the aromatic rings increasing, the peak intensity increased in the fine mode. Na, Ca, Al, Mg and K dominated the elemental mass profiles, and metals displayed a bimodal distribution with a dominant peak in the coarse range. The total PAH deposition flux was 123.6 and 53.1 ng/h for adults and children, respectively. Coarse particles contributed most deposition flux in the head region, while fine particles contribute most deposition flux in the alveolar region. The increment lifetime cancer risk (ILCR) of PAHs ranaged at 10-5-10-4, indicating potential cancer risk to human health. The total deposition flux of metals was estimated at 1.4-13.2 ng/h. With the size increasing, deposition flux increased in the head region while decreased in the alveolar region. The highest ILCR of Cr and Ni were 4.9 * 10-5 and 1.5 * 10-6, respectively, exceeding the permissible risk of 10-6. The hazard quotient (HQ) of Fe (10-5-10-4) and Zn (10-6-10-5) were much lower than the safe level of 1.0, and thus they were not considered as a health concern. PMID- 29452714 TI - Genetic diversity and structure of Rhizobium leguminosarum populations associated with clover plants are influenced by local environmental variables. AB - The identification and conservation of indigenous rhizobia associated with legume plants and their application as biofertilizers is becoming an agricultural worldwide priority. However, little is known about the genetic diversity and phylogeny of rhizobia in Romania. In the present study, the genetic diversity and population composition of Rhizobium leguminosarum symbiovar trifolii isolates from 12 clover plants populations located across two regions in Romania were analyzed. Red clover isolates were phenotypically evaluated and genotyped by sequencing 16S rRNA gene, 16S-23S intergenic spacer, three chromosomal genes (atpD, glnII and recA) and two plasmid genes (nifH and nodA). Multilocus sequence typing (MLST) analysis revealed that red clover plants are nodulated by a wide genetic diversity of R. leguminosarum symbiovar trifolii sequence types (STs), highly similar to the ones previously found in white clover. Rhizobial genetic variation was found mainly within the two clover populations for both chromosomal and plasmid types. Many STs appear to be unique for this region and the genetic composition of rhizobia differs significantly among the clover populations. Furthermore, our results showed that both soil pH and altitude contributed to plasmid sequence type composition while differences in chromosomal composition were affected by the altitude and were strongly correlated with distance. PMID- 29452715 TI - Cyanobacteria inhabiting biological soil crusts of a polar desert: Sor Rondane Mountains, Antarctica. AB - Molecular and morphological methods were applied to study cyanobacterial community composition in biological soil crusts (BSCs) from four areas (two nunataks and two ridges) in the Sor Rondane Mountains, Antarctica. The sampling sites serve as control areas for open top chambers (OTCs) that were put in place in 2010 at the time of sample collection and will be compared with BSC samples taken from the OTCs in the future. Cyanobacterial cell biovolume was estimated using epifluorescence microscopy, which revealed the dominance of filamentous cyanobacteria in all studied sites except the Utsteinen ridge, where unicellular cyanobacteria were the most abundant. Cyanobacterial diversity was studied by a combination of molecular fingerprinting methods based on the 16S rRNA gene (denaturing gradient gel electrophoresis (DGGE) and 454 pyrosequencing) using cyanobacteria-specific primers. The number of DGGE sequences obtained per site was variable and, therefore, a high-throughput method was subsequently employed to improve the diversity coverage. Consistent with previous surveys in Antarctica, both methods showed that filamentous cyanobacteria, such as Leptolyngbya sp., Phormidium sp. and Microcoleus sp., were dominant in the studied sites. In addition, the studied localities differed in substrate type, climatic conditions and soil parameters, which probably resulted in differences in cyanobacterial community composition. Furthermore, the BSC growing on gneiss pebbles had lower cyanobacterial abundances than BSCs associated with granitic substrates. PMID- 29452716 TI - Dental Pulp Status of Posterior Teeth in Patients with Oral and Oropharyngeal Cancer Treated with Radiotherapy: 1-year Follow-up. AB - INTRODUCTION: Teeth may react negatively to pulp sensitivity testing in patients who have undergone radiotherapy. The aim of the current investigation was to evaluate the pulp sensibility of posterior teeth at 4, 6, and 12 months in patients who have undergone radiotherapy for oral and oropharyngeal malignancies. METHODS: Seventy-nine patients diagnosed with malignant oral and oropharyngeal cancer undergoing radiotherapy underwent cold thermal pulp sensitivity testing and electric pulp testing of 4 teeth, 1 from each quadrant. The results were recorded at 5 different time points (TPs): before radiotherapy (TP1), at the end of radiotherapy at 66-70 Gy (TP2), 4 months after the completion of radiotherapy (TP3), 6 months after the completion of radiotherapy (TP4), and 12 months after the completion of radiotherapy (TP5). RESULTS: All 288 teeth tested positive to cold thermal pulp sensitivity testing and electric pulp testing (EPT) at TP1 (100%). No tooth responded to the cold test (100%) at TP4 and TP5, and progressively higher EPT values were noted during the observation period. A statistically significant difference existed in the number of positive responses between different TPs. CONCLUSIONS: There was a progressive decrease in pulp sensibility from TP1 to TP5 in teeth of patients with oral and oropharyngeal cancer who underwent radiotherapy (66-70 Gy). No response to cold thermal tests was noted at TP4 (6 months) and TP5 (12 months), and teeth responded at increasingly higher EPT values from TP1 through TP5. This result was statistically significant. PMID- 29452717 TI - Evaluation of the mobility of the shoulder and quality of life after perforator flaps for recalcitrant axillary hidradenitis. AB - BACKGROUND: Hidradenitis suppurativa is a very debilitating disease, treated by antibiotics and excision. The reconstruction is usually done by secondary wound healing and/or split-thichness skin graft. The aim of this study was to evaluate the reconstruction of the axilla with local perforator flaps as a single stage surgical treatment. METHODS: This was a monocentric retrospective study conducted between November 2013 and June 2015. We included the patients with a severe axillary localization of the disease. Between 6 months and 1 year postoperatively, we noted length of complete healing, complications, patients satisfaction score about the surgery, DASH functional score, maximum abduction angle of the arm, and recurrence of the disease. RESULTS: Thirteen patients were included, for a total of seventeen affected axillae. We performed seven thoracodorsal artery perforator flaps, seven lateral intercostal artery perforator flaps and three serratus anterior artery perforator flaps. The mean duration of follow-up was 279.1+/-84.1 days (180-365). The average complete healing time was 20.5+/-13.5 days (10-60). Six axillae were compounded (35%). The average recurrence rate of HS was 0%. The average score in the DASH questionnaire was 68.6+/-35.3 points (39-152) and the average maximum abduction angle of the arm was 160.6+/-18.5 degrees. The average score on the satisfaction questionnaire was 36.5+/-5.6 points (25-43). CONCLUSION: This is a single stage, reliable and effective surgical procedure. The results are very encouraging, with a good quality of life, a low functional disability and a shorter healing time. PMID- 29452718 TI - Health policies for the reduction of obstetric interventions in singleton full term births in Catalonia. AB - AIM: To explore the effect of hospital's characteristics in the proportion of obstetric interventions (OI) performed in singleton fullterm births (SFTB) in Catalonia (2010-2014), while incentives were employed to reduce C-sections. METHODS: Data about SFTB assisted at 42 public hospitals were extracted from the dataset of hospital discharges. Hospitals were classified according to the level of complexity, the volume of births attended, and the adoption of a non medicalized delivery (NMD) strategy. The annual average change in the percentage for OI was calculated based on Poisson regression models. RESULTS: The rate of OI (35% of all SFTB) including C-sections (20.6%) remained stable through the period. Hospitals attending less complex cases had a lower average of OI, while hospitals attending lower volumes had the highest average. Higher levels of complexity increased the use of C-sections (+4% yearly) and forceps (+16%). The adoption of the NMD strategy decreased the rate of C-sections. CONCLUSIONS: The proportion of OI, including C-sections, remained stable in spite of public incentives to reduce them. The adoption of the NMD strategy could help in decreasing the rate of OI. To reduce the OI rate, new strategies should be launched as the development of low-risk pregnancies units, alignment of incentives and hospital payment, increased value of incentives and encouragement of a cultural shift towards non-medicalized births.

PMID- 29452720 TI - Evaluation of the biological activities of the IL-15 superagonist complex, ALT 803, following intravenous versus subcutaneous administration in murine models. AB - ALT-803 is a fusion protein complex consisting of an interleukin (IL)-15 superagonist and a dimeric IL-15 receptor alpha sushi domain IgG1 Fc fusion protein. When administered to mice, ALT-803 is capable of inducing natural killer (NK) and CD8+ T cell proliferation and activation, and effectively promoting potent anti-tumor responses. Currently, ALT-803 is in clinical trials for treatment of various solid tumors and hematological malignancies. In the initial phase of these clinical studies, intravenous (iv) injection was used according to the route used in pre-clinical efficacy studies. In order to evaluate the possible advantage of subcutaneous (sc) injection versus iv injection, this study compared the biological activity of the two treatment regimens of ALT-803 in pre clinical in vivo models. The pharmacokinetics, immune stimulation, and anti-tumor efficacy of iv and sc injection routes of ALT-803 in C57BL/6 mice were compared. The half-life of ALT-803 was 7.5 h for iv versus 7.7 h for sc with the maximal detected serum concentration of ALT-803 to be 3926 ng/ml at 0.5 h time-point following iv injection versus 495 ng/ml at 16 h post sc injection. Biodistribution studies indicated that sc ALT-803, similarly to iv ALT-803 as previously reported, has a greater tissue distribution and longer residence time in lymphoid tissues compared to recombinant IL-15. Notably, ALT-803 when administered either iv or sc induced comparable proliferation and activation of CD8+ T and NK cells and resulted in similar reductions of tumor burden. A toxicity study of mice receiving multiple injections of ALT-803 for 4 weeks by iv or sc routes revealed equivalent immune-related changes. The gradual absorbance into the blood stream and lower maximal blood levels of ALT-803 in sc-injected mice, along with similar anti-tumor efficacy support the administration of ALT 803 by sc injection in patients with various malignancies and infectious diseases. PMID- 29452721 TI - Use of the Gore Tigris Vascular Stent in Advanced Femoropopliteal Peripheral Arterial Disease. AB - PURPOSE: To prospectively evaluate the safety and efficacy of using the Tigris vascular stent (Gore, Flagstaff, Arizona) alone or in combination with the Viabahn stent (Gore) for revascularizing femoropopliteal Trans-Atlantic Intersociety Consensus (TASC) type B-D lesions with varying degrees of calcification. MATERIALS AND METHODS: Patients with Rutherford stage >= 3 and TASC type >= B were included in the study. From January 2015 to April 2017, 31 segments in 31 patients (21 men, ovarall mean age 73.3 +/- 9.2 years) were treated. The breakdown by TASC type and Rutherford stage were TASC B (n = 12), C (n = 6), and D (n = 13), and Rutherford 3 (n = 28) and 4 (n = 3). The lesions were located in the common femoral artery (n = 1), superficial femoral artery (SFA; n = 20), distal SFA to P1 (n = 3), popliteal P1 (n = 1), popliteal P1-3 (n = 3), popliteal P2-3 (n = 2), and 1 femoropopliteal bypass. There were 18 occlusions (58.1%) and 13 stenoses (41.9%). The mean diseased segment length was 15.5 +/- 9.9 cm with 80.6% of moderate/severe calcification. The follow-up consisted of color Doppler ultrasound and clinical assessment at 1, 3, 6, 9, 12, and 15 months. RESULTS: Technical success was 100%. There were no periprocedural or postprocedural complications. The mean stented lesion length was 17.2 +/- 10.5 cm with a mean follow-up of 13.1 +/- 6.9 months. Primary patency rates at 6, 9, 12, and 15 months were, respectively, 100% (24/31 patients), 90.5% (21/31 patients), 88.9% (20/31 patients), and 80% (15/31 patients). The median postprocedural Rutherford stage was 1. Three occlusions occurred at 7, 9, and 14 months, leading to a target lesion revascularization of 9.7% and a secondary patency of 100% at 15 months. Logistic analysis results demonstrated that lesion length (P = .003) was associated with reocclusion. Amputation-free survival at 15 months was 100%. Intrastent restenosis was observed in four cases (12.9%) but none were associated with worsening of symptoms. No stent fractures were observed. CONCLUSIONS: The Tigris stent used alone or in combination with a Viabahn stent for femoropopliteal TASC B-D lesions demonstrated acceptable 12 month primary patency with a low reintervention rate. PMID- 29452722 TI - Traumatic Lingual Hematoma Resulting in Bilateral Temporal Mandibular Joint Dislocations. AB - BACKGROUND: Lingual hematoma (LH) is a relatively uncommon entity seen after both medical and traumatic etiologies. Regardless of the cause, the feared complication is acute airway obstruction. CASE REPORT: Our case involves a 39 year-old man who presented to the Emergency Department via emergency medical services with an enlarging LH after an unwitnessed fall, suspected to be an alcohol withdrawal seizure. The bleeding was likely exacerbated by previously undiagnosed thrombocytopenia. Airway stabilization was rapidly established via nasotracheal intubation after standard intubation techniques were deemed unfeasible. Despite correction of the coagulopathy, the LH continued to expand, resulting in bilateral tympanomandibular joint (TMJ) dislocations. To our knowledge, this complication has not been previously reported as a complication of LH. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Despite being a relatively uncommon condition, LH has the potential to result in life-threatening airway obstruction with limited airway options. Prompt airway stabilization should be the first priority upon diagnosis. A rapidly evolving LH can limit standard orotracheal rapid sequence intubation options, and may require alternative airway procedures. Additionally, ongoing lingual swelling after airway stabilization has now been shown in our case to result in bilateral TMJ dislocations. Concurrent management of reversible coagulopathy may help prevent this complication or reduce its severity. PMID- 29452723 TI - Q-marker based strategy for CMC research of Chinese medicine: A case study of Panax Notoginseng saponins. AB - BACKGROUND: To ensure pharmaceutical quality, chemistry, manufacturing and control (CMC) research is essential. However, due to the inherent complexity of Chinese medicine (CM), CMC study of CM remains a great challenge for academia, industry, and regulatory agencies. Recently, quality-marker (Q-marker) was proposed to establish quality standards or quality analysis approaches of Chinese medicine, which sheds a light on Chinese medicine's CMC study. PURPOSE: Here manufacture processes of Panax Notoginseng Saponins (PNS) is taken as a case study and the present work is to establish a Q-marker based research strategy for CMC of Chinese medicine. STUDY DESIGN: The Q-markers of Panax Notoginseng Saponins (PNS) is selected and established by integrating chemical profile with pharmacological activities. Then, the key processes of PNS manufacturing are identified by material flow analysis. Furthermore, modeling algorithms are employed to explore the relationship between Q-markers and critical process parameters (CPPs) of the key processes. At last, CPPs of the key processes are optimized in order to improving the process efficiency. RESULTS: Among the 97 identified compounds, Notoginsenoside R1, ginsenoside Rg1, Re, Rb1 and Rd are selected as the Q-markers of PNS. Our analysis on PNS manufacturing show the extraction process and column chromatography process are the key processes. With the CPPs of each process as the inputs and Q-markers' contents as the outputs, two process prediction models are built separately for the extraction process and column chromatography process of Panax notoginseng, which both possess good prediction ability. Based on the efficiency models of extraction process and column chromatography process we constructed, the optimal CPPs of both processes are calculated. CONCLUSION: Our results show that the Q-markers derived from CMC research strategy can be applied to analyze the manufacturing processes of Chinese medicine to assure product's quality and promote key processes' efficiency simultaneously.

AB - Proton beam therapy (PBT) is still relatively new in cancer treatment and the clinical evidence base is relatively sparse. Mathematical modelling offers assistance when selecting patients for PBT and predicting the demand for service.

PMID- 29452725 TI - Base of tongue cancer-is it tongue cancer located at the base of the tongue, or is it a type of lingual tonsil cancer? The perspective from a genomic analysis. AB - The aim of this study was to determine whether base of tongue (BOT) cancer is tongue cancer located at the base of the tongue or lingual tonsil cancer originating from tonsil tissue. This was a retrospective study using data from The Cancer Genome Atlas (TCGA). The genomic patterns of three primary cancers (BOT, oral tongue, and tonsil) were compared to determine their similarities and differences. Gene expression data (n=193; 26 BOT, 125 oral tongue, and 42 tonsil cases), copy number alteration data (n=142; 19 BOT, 96 oral tongue, and 27 tonsil cases), and somatic mutation data (n=187; 25 BOT, 122 oral tongue, and 40 tonsil cases) were analyzed using the t-test, heatmap analysis, and OncoPrint, respectively. Clinical information for the three tumour groups was included in the analyses. When using multiplatform analysis, BOT cancer showed nearly the same genomic pattern as tonsil cancer, but not oral tongue cancer. The chi2 test and survival analysis revealed that BOT cancer had the same clinical and survival patterns as tonsil cancer. In conclusion, BOT cancer showed a genomic pattern similar to that of tonsil cancer, but different to that of oral tongue cancer. Further prospective studies are warranted before the results of this study can be applied in a clinical setting. PMID- 29452726 TI - Randomized clinical trial on condylar fractures: 'open or closed'? PMID- 29452727 TI - A systematic review and meta-analysis of sleep architecture and chronic traumatic brain injury. AB - Sleep quality appears to be altered by traumatic brain injury (TBI). However, whether persistent post-injury changes in sleep architecture are present is unknown and relatively unexplored. We conducted a systematic review and meta analysis to assess the extent to which chronic TBI (>6 months since injury) is characterized by changes to sleep architecture. We also explored the relationship between sleep architecture and TBI severity. In the fourteen included studies, sleep was assessed with at least one night of polysomnography in both chronic TBI participants and controls. Statistical analyses, performed using Comprehensive Meta-Analysis software, revealed that chronic TBI is characterized by relatively increased slow wave sleep (SWS). A meta-regression showed moderate-severe TBI is associated with elevated SWS, reduced stage 2, and reduced sleep efficiency. In contrast, mild TBI was not associated with any significant alteration of sleep architecture. The present findings are consistent with the hypothesis that increased SWS after moderate-severe TBI reflects post-injury cortical reorganization and restructuring. Suggestions for future research are discussed, including adoption of common data elements in future studies to facilitate cross study comparability, reliability, and replicability, thereby increasing the likelihood that meaningful sleep (and other) biomarkers of TBI will be identified. PMID- 29452728 TI - Effects of advance care planning on confidence in surrogates' ability to make healthcare decisions consistent with older adults' wishes: Findings from a randomized controlled trial. AB - OBJECTIVE: To investigate how confidence in surrogates' ability to make consistent decisions in the future change over time, in the context of an ACP intervention that did not improve surrogates' ability to predict an older adult's hypothetical treatment preferences. METHODS: The study involved 235 older adults and surrogates, randomly allocated to an ACP or control intervention. At baseline, end of intervention, and six months later, participants were asked how confident they were in the surrogate making decisions in the future that would match the older adult's wishes. RESULTS: By the end of the intervention, confidence had increased among older adults and surrogates involved in ACP (OR = 3.1 and 5.8 respectively, p < 0.001), while less change occurred among controls. Over the following six months, confidence remained stable among older adults but decreased among surrogates (OR = 0.5, p = 0.005). CONCLUSION: ACP increases confidence in surrogates' ability to make consistent decisions, which may lighten the burden of substitute decision making. Efforts to improve substitute decision making must continue so that participants' confidence is not based on the mistaken assumption that surrogates can make consistent decisions. PRACTICE IMPLICATIONS: Professionals involved in ACP should inform participants that confidence in the surrogate may increase in the absence of enhanced predictive ability.

AB - BACKGROUND: To describe and compare incidence, characteristics and outcomes of postoperative pneumonia among patients with or without COPD. METHODS: We included hospitalized patients aged >=40 years whose medical diagnosis included pneumonia and ventilator-associated pneumonia in the secondary's diagnosis field and who were discharged from Spanish hospitals from 2001 to 2015. Irrespectively of the position at the procedures coding list, we retrieved data about the type of surgical procedures using the enhanced ICD-9-CM codes. We grouped admissions by COPD status. The data were collected from the National Hospital Discharge Database. RESULTS: We included 117,665 hospitalizations of patients that developed postoperative pneumonia (18.06% of them had COPD). The incidence of postoperative pneumonia was significantly higher in COPD patients than in those without COPD (IRR 1.93, 95%CI 1.68-2.24). In hospital-mortality (IHM) was significantly lower in the first group of patients (29.79% vs 31.43%, p < 0.05). Factors independently associated with IHM, among COPD and non-COPD patients, were older age, more comorbidities, mechanical ventilation, pleural drainage tube, red blood cell transfusion, dialysis and emergency room admission. Time trend analysis showed a significant decrease in IHM from 2001 to 2015. COPD was associated with lower IHM (OR 0.91, 95%CI 0.88-0.95). CONCLUSIONS: The incidence of postoperative pneumonia was higher in COPD patients than in those without this disease. However, IHM was lower among COPD patients. IHM decreased over time, regardless of the existence or not of COPD.

AB - INTRODUCTION: Early warning scores (EWS) have been developed to identify the degree of illness severity among acutely ill patients. One system, The Laboratory Decision Tree Early Warning Score (LDT-EWS) is wholly laboratory data based. Laboratory data was used in the development of a rare computerized method, developing a decision tree analysis. This article externally validates LDT-EWS, which is obligatory for an EWS before clinical use. METHOD: We conducted a retrospective review of prospectively collected data based on a time limited sample of all patients admitted through the medical admission unit (MAU) on a Danish secondary hospital. All consecutive adult patients admitted from 2 October 2008 until 19 February 2009, and from 23 February 2010 until 26 May 2010, were included. Validation was made by calculating the discriminatory power as area under the receiver-operating curve (AUROC) and calibration (precision) as Hosmer Lemeshow Goodness of fit test. RESULTS: A total of 5858 patients were admitted and 4902 included (83.7%). In-hospital mortality in our final dataset (n=4902) was 3.5%. Discriminatory power (95% CI), identifying in-hospital death was 0.809 (0.777-0.842). Calibration was good with a goodness-of-fit test of X2=5.37 (7 degrees of freedom), p=0.62. CONCLUSION: LDT-EWS has acceptable ability to identify patients at high risk of dying during hospitalization with good precision. Further studies performing impact analysis are required before this score should be implemented in clinical practice. PMID- 29452731 TI - Submersion injuries in the United States: Patients characteristics and predictors of mortality and morbidity. AB - INTRODUCTION: Drowning leads to 372,000 deaths annually worldwide and to severe morbidity secondary to asphyxiation or aspiration. Previous studies described submersion injuries mainly in the pediatric population. This study describes characteristics of patients presenting with submersion injuries to United States emergency departments (EDs) and identifies predictors of poor outcomes (death or long term neurologic deficits) after drowning. METHODS: This retrospective cross sectional study included ED visits for submersion injuries from the United States 2013 Nationwide Emergency Department Sample (NEDS) dataset using discharge data (CCS diagnosis codes). Descriptive analysis was done for the collected variables and was followed by a multivariate regression analysis to identify predictors of poor outcomes (mortality and morbidity). RESULTS: A total of 12,529 weighted patients presented to EDs for submersion injury in 2013 yielding a rate of 9.29 per 100,000 ED visits. Patients were more frequently males (65.8%, 95%CI: 64.0 67.6) and in the 19-65 years age group (41.8%, 95%CI: 40.0-43.6). Poor outcomes were present in 11.7% (95%CI: 10.5-13.0) of patients. Significant positive predictors of poor outcomes were: male gender (OR = 1.761, 95%CI: 1.247-2.487); presence of chronic conditions involving infectious and parasitic disease (OR = 2.824, 95%CI: 1.155-6.908), the circulatory system (OR = 12.818, 95%CI: 8.953 18.351), the respiratory system (OR = 1.498, 95%CI: 1.079-2.079) or the digestive system (OR = 2.006, 95%CI: 1.106-3.636); associated motor vehicle traffic injury (OR = 5.221, 95%CI: 1.563-17.441) and self-payers. CONCLUSION: Submersion remains a high impact emergency condition in the United States. Significant predictors of poor outcomes were identified. Prevention efforts targeting susceptible population are needed to reduce the impact of submersion injuries on different communities in the United States. PMID- 29452732 TI - Efficacy of pre-hospital rapid sequence intubation in paediatric traumatic brain injury: A 9-year observational study. AB - INTRODUCTION: Prehospital airway management of the paediatric patient with traumatic brain injury (TBI) is controversial. Endotracheal intubation of children in the field requires specific skills and has potential benefits but also carries potentially serious complications. We aimed to compare mortality and functional outcomes after six months between children with TBI who either underwent prehospital rapid sequence intubation (RSI) by trained Intensive Care paramedics (ICP) or received no intubation. METHODS: We conducted a retrospective study of patients aged <=14 years with suspected TBI in Victoria, Australia. Patients were either transported via helicopter and received RSI by an ICP (2005 2013) or via road ambulance and received no intubation (2006-2013). Prehospital data was linked to hospital and 6-month follow-up data to assess mortality and functional outcome. RESULTS: A total of 106 patients were included in the study of which 87 received RSI by paramedics and 19 did not receive intubation. Overall, the intubation success rate was 99% (86/87), with a first-pass success rate of 93% (81/87). In total, 67% of patients (n = 41) receiving RSI had a favourable functional outcome, compared with 54% of non-intubated patients (n = 7) (p = 0.36). In the 75 children with major trauma, prehospital RSI was associated with a significant decrease in length of hospital stay (523 h vs. 1939 h, p = 0.03). In the 53 children in this subgroup with available six months data the difference in favourable functional outcome increased to 66% (n = 31)vs. 17% (n = 1) (p = 0.06). DISCUSSION: Prehospital RSI in paediatric patients with TBI can safely be performed by highly trained paramedics. Overall, we observed more favourable long-term outcomes in patients who received prehospital intubation than those who did not, however our study is not powered to detect a significant difference. Intubation prior to transport might be beneficial for major trauma patients. PMID- 29452733 TI - Trajectory of physical activity after hip fracture: An analysis of community dwelling individuals from the English Longitudinal Study of Ageing. AB - INTRODUCTION: To analyse physical activity participation in a community-dwelling people in England with hip fracture the interval prior to fracture, in the fracture recovery period, and a minimum of two years post-fracture. MATERIALS AND METHODS: 215 individuals were identified from the English Longitudinal Study of Ageing cohort (2002-2014) who sustained a hip fracture following a fall and for whom data were available on physical activity participation relating to the period pre-fracture, within-fracture recovery phase and post-fracture (minimum of two years). Physical activity was assessed using the validated ELSA physical activity questionnaire. Prevalence of 'low' physical activity participation was calculated and multi-level modelling analyses were performed to explore physical activity trajectories over the follow-up phase, and whether age, depression, gender and frailty were associated with physical activity participation. RESULTS: Prevalence of low physical activity participation within two years prior to hip fracture was 16.7% (95% Confidence Intervals (CI): 11.6% to 21.8%). This increased at the final follow-up phase to 21.3% (95% CI: 15.1% to 27.6%). This was not a statistically significant change (P = 0.100). Age (P = 0.005) and frailty (P < 0.001) were statistically significant explanatory variables (P = 0.005) where older age and greater frailty equated to lower physical activity participation. Neither gender (P = 0.288) nor depression (P = 0.121) were significant explanatory variables. CONCLUSION: Physical activity levels do not significantly change between pre-fracture to a minimum of two years post-hip fracture for community-dwelling individuals. This contrasts with previous reports of reduced mobility post-hip fracture, suggesting that 'physical activity' and 'mobility' should be considered as separate outcomes in this population. PMID- 29452734 TI - Calcar screw position in proximal humerus fracture fixation: Don't miss high! AB - INTRODUCTION: In locked plate fixation of proximal humerus fractures, the calcar is an important anchor point for screws providing much-needed medial column support. Most locking plate implants utilize a fixed-trajectory locking screw to achieve this goal. Consequently, adjustments of plate location to account for patient-specific anatomy may result in a screw position outside of the calcar. To date, little is known about the consequences of "missing" the calcar during plate positioning. This study sought to characterize the biomechanics associated with proximal and distal placement of locking plates in a two-part fracture model. MATERIALS AND METHODS: This experiment was performed twice, first with elderly cadaveric specimens and again with osteoporotic sawbones. Two-part fractures were simulated and specimens were divided to represent proximal, neutral, and distal plate placements. Non-destructive torsional and axial compression tests were performed prior to an axial fatigue test and a ramp to failure. Torsional stiffness, axial stiffness, humeral head displacement and stiffness during fatigue testing, and ultimate load were compared between groups. RESULTS: Cadavers: Proximal implant placement led to trends of decreased mechanical properties, but there were no significant differences found between groups. Sawbones: Distal placement increased torsional stiffness in both directions (p = 0.003, p = 0.034) and axial stiffness (p = 0.018) when compared to proximal placement. Distal placement also increased torsional stiffness in external rotation (p = 0.020), increased axial stiffness (p = 0.024), decreased humeral head displacement during fatigue testing, and increased stiffness during fatigue testing when compared to neutral placement. DISCUSSION: The distal and neutral groups had similar mechanical properties in many cadaveric comparisons while the proximal group trended towards decreased construct stiffness. RESULTS: from the Sawbones model were more definitive and provided further evidence that proximal calcar screw placements are undesirable and distal implant placement may provide improved construct stability. CONCLUSION: Successful proximal humerus fracture reconstruction is inherent upon anatomic fracture reduction coupled with medial column support. Results from this experiment suggest that missing the calcar proximally is deleterious to fixation strength, while it is safe, and perhaps even desirable, to aim slightly distal to the intended target.

AB - OBJECTIVE: To evaluate the epidemiology of sudden unexpected infant death (SUID) over a 20-year period in the US, to assess the potential frequency of sudden unexpected postnatal collapse in the early days of life, and to determine if SUID rates in the neonatal period (0-27 days) have changed in parallel with rates in the postneonatal periods, including the percentages attributed to codes that include accidental suffocation. STUDY DESIGN: Data from the US Centers for Disease Control and Prevention Linked Birth/Infant Death Records for 1995-2014 were analyzed for the first hour, day, week, and month of life. A comparison of neonatal and postneonatal data related to SUID, including accidental suffocation, was carried out. RESULTS: Death records for 1995-2014 indicate that, although SUID rates in the postneonatal period have declined subsequent to the 1992 American Academy of Pediatrics sleep position policy change, newborn SUIDs have failed to decrease, and the percentage of SUIDs attributed to unsafe sleep conditions has increased significantly in both periods; 29.2% of the neonatal cases occurred within the first 6 days of life. CONCLUSIONS: The frequency of SUIDs during the neonatal period warrants ongoing attention to all circumstances contributing to this category of deaths. The development of a standardized definition of sudden unexpected postnatal collapse and a national registry of these events is recommended. Ongoing research on the effects of early neonatal practices on postneonatal SUID should also be encouraged.

AB - RATIONALE AND OBJECTIVE: To identify the influence of various parameters for reducing artifacts in computed tomography (CT) of commonly used pacemakers or implantable cardioverter-defibrillator (ICD) lead tips. MATERIALS AND METHODS: This ex vivo phantom study compared two CT techniques (Dual-Energy CT [DECT] vs. Dual-Source CT [DSCT]), as well as the influence of incremental alterations of current-time product and pacemaker lead-tip angle with respect to the gantry plane. Four pacemaker leads and one ICD lead were evaluated. The images were assessed visually on a five-point Likert scale (1 = artifact free to 5 = massive artifacts). Likert values 1-3 represent clinically relevant, diagnostic image quality. RESULTS: 344 of 400 total images were rated with diagnostic image quality. The DECT and dual-source DSCT technique each scored 86% diagnostic image quality. Statistically, DECT images showed significantly improved image quality (P < .05). Concerning the current-time product, no statistically significant change was found. Regarding lead-tip positioning, an angle of <=70 degrees yielded 100% diagnostic image quality. Pacemaker and ICD leads were assessed to have statistically significant differences. CONCLUSIONS: Surprisingly, the lead tip angle of 70 degrees has been established as the key angle under which diagnostic image quality is always ensured, regardless of the imaging technique. Thus, we call 70 degrees the "Magic angle" in CT pacemaker imaging. PMID- 29452742 TI - To switch from Botox to Dysport in children with CP, a real world, dose conversion, cost-effectiveness study. AB - BACKGROUND AND OBJECTIVES: Children with cerebral palsy (CP) are routinely treated with botulinum toxin A (BoNT-A). Two non dose-equivalent and differently priced products, Botox and Dysport are used. Depending on the conversion one of the products is considerably cheaper. However, the dose conversion factors studied to date have varied widely and relevant studies have not included children. Our objective here was to compare the efficacy and health economics of the switch from Botox to Dysport in children with CP when conversion was set to 1:2. Specifically were these treatments perceived as equivalent in terms of efficacy, duration and side-effects and were the drug cost lowered by using Dysport. METHODS: This prospective, real-world, cost-effectiveness population based observational study included all children with CP, (n = 159) mean age 9.4 years (SD, 4.3), in the larger Stockholm area who received BoNT-A between September 1, 2014, and December 31, 2015. Parents reported the efficacy, duration and side-effects of previous treatment while physicians reported doses and goals set by children and parents for the present treatment. Drug acquisition costs were provided by county administrators. RESULTS: In connection with 341 visits caregivers reported comparable effects of similar duration with these products, with few, similar and transient side-effects. The drug-cost per treatment was 4029 SEK for Botox and 2380 SEK in the case of Dysport. CONCLUSION: When Botox was replaced by a two-fold higher Unit dose of Dysport (conversion 1:2) parents perceived the treatment of their children with CP to be equally effective while the cost was 41% lower according to procured prices. PMID- 29452743 TI - Medication wasted - Contents and costs of medicines ending up in household garbage. AB - BACKGROUND: Despite potentially considerable implications for public health, the environment and public funds, medicine waste is an under-researched topic. This study aims to analyse medicines drawn from household garbage in Vienna (Austria) and to assess possible financial implications for public payers. METHODS: Four pharmaceutical waste samples collected by the Vienna Municipal Waste Department between April 2015 and January 2016 were investigated with regard to their content. The value of medicines was assessed at ex-factory, reimbursement and pharmacy retail price levels, and the portion of costs attributable to the social health insurance was determined. Data were extrapolated for Vienna and Austria. RESULTS: The waste sample contained 1089 items, of which 42% were excluded (non pharmaceuticals, non-Austrian origin and non-attributable medicines). A total of 637 items were further analysed. Approximately 18% of these medicines were full packs. 36% of the medicines wasted had not yet expired. Nearly two out of three medicines wasted were prescription-only medicines. The majority were medicines related to the 'alimentary tract and metabolism' (ATC code A), the 'nervous system' (ATC code N) and the 'respiratory system' (ATC code R). The medicines wasted had a total value of ? 1965, ? 2987 and ? 4207, expressed at ex-factory, reimbursement and pharmacy retail price levels, respectively. Extrapolated for Vienna, at least ? 37.65 million in terms of expenditure for public payers were wasted in household garbage, corresponding to ? 21 per inhabitant. CONCLUSION: This study showed that in Vienna some medicines end up partially used or even completely unused in household garbage, including prescription-only medicines, non-expired medicines and medicines for chronic diseases. While there might be different reasons for medicines being wasted, the findings suggest possible adherence challenges as one issue to be addressed. PMID- 29452744 TI - Emerging concepts in diagnosis and treatment of syncope by pacing. AB - Neuroendocrine syncope is a newly proposed term to embody both syncope of reflex and adenosine-related etiology. Recent publications on tilt testing have revealed the presence of a hypotensive tendency in some patients, even in the face of severe cardioinhibition. This new understanding may allow better selection of older reflex syncope patients, documented by ECG loop recorder, for successful pacing where tilt testing is ideally negative for a good result in terms of few syncope recurrences and prompts a less aggressive management policy when hypotensive medication is required. Furthermore, plasma adenosine levels not only define a new group of patients who have low adenosine and will respond well to cardiac pacing but also, by assessing adenosine receptor affinity, offer a possible explanation for vasodepression accompanying severe cardioinhibition. The question of the timing of loss of consciousness in reflex syncope needs to be addressed because, if consciousness is lost before asystole, pacing is likely to be ineffective.

PMID- 29452747 TI - Accuracy of Clinician Practice Compared With Three Head Injury Decision Rules in Children: A Prospective Cohort Study. AB - STUDY OBJECTIVE: Three clinical decision rules for head injuries in children (Pediatric Emergency Care Applied Research Network [PECARN], Canadian Assessment of Tomography for Childhood Head Injury [CATCH], and Children's Head Injury Algorithm for the Prediction of Important Clinical Events [CHALICE]) have been shown to have high performance accuracy. The utility of any of these in a particular setting depends on preexisting clinician accuracy. We therefore assess the accuracy of clinician practice in detecting clinically important traumatic brain injury. METHODS: This was a planned secondary analysis of a prospective observational study of children younger than 18 years with head injuries at 10 Australian and New Zealand centers. In a cohort of children with mild head injuries (Glasgow Coma Scale score 13 to 15, presenting in <24 hours) we assessed physician accuracy (computed tomography [CT] obtained in emergency departments [EDs]) for the standardized outcome of clinically important traumatic brain injury and compared this with the accuracy of PECARN, CATCH, and CHALICE. RESULTS: Of 20,137 children, 18,913 had a mild head injury. Of these patients, 1,579 (8.3%) received a CT scan during the ED visit, 160 (0.8%) had clinically important traumatic brain injury, and 24 (0.1%) underwent neurosurgery. Clinician identification of clinically important traumatic brain injury based on CT performed had a sensitivity of 158 of 160, or 98.8% (95% confidence interval [CI] 95.6% to 99.8%) and a specificity of 17,332 of 18,753, or 92.4% (95% CI 92.0% to 92.8%). Sensitivity of PECARN for children younger than 2 years was 42 of 42 (100.0%; 95% CI 91.6% to 100.0%), and for those 2 years and older, it was 117 of 118 (99.2%; 95% CI 95.4% to 100.0%); for CATCH (high/medium risk), it was 147 of 160 (91.9%; 95% CI 86.5% to 95.6%); and for CHALICE, 148 of 160 (92.5%; 95% CI 87.3% to 96.1%). CONCLUSION: In a setting with high clinician accuracy and a low CT rate, PECARN, CATCH, or CHALICE clinical decision rules have limited potential to increase the accuracy of detecting clinically important traumatic brain injury and may increase the CT rate. PMID- 29452748 TI - Knockout of human muscle genes revealed by large scale whole-exome studies. AB - Large scale whole-exome sequence studies have revealed that a number of individuals from different populations have predicted loss-of-function of different genes due to nonsense, frameshift, or canonical splice-site mutations. Surprisingly, many of these mutations do not apparently show the deleterious phenotypic consequences expected from gene knockout. These homozygous null mutations, when confirmed, can provide insight into human gene function and suggest novel approaches to correct gene dysfunction, as the lack of the expected disease phenotype may reflect the existence of modifier genes that reveal potential therapeutic targets. Human knockouts complement the information derived from mouse knockouts, which are not always good models of human disease. We have examined human knockout datasets searching for genes expressed exclusively or predominantly in striated muscle. A number of well-known muscle genes was found in one or more datasets, including genes coding for sarcomeric myosins, components of the sarcomeric cytoskeleton, sarcoplasmic reticulum and plasma membrane, and enzymes involved in muscle metabolism. The surprising absence of phenotype in some of these human knockouts is critically discussed, focusing on the comparison with the corresponding mouse knockouts. PMID- 29452749 TI - Children's physical activity levels during organised sports practices. AB - OBJECTIVES: This study measured the physical activity levels of children during practice sessions of four popular organised sports in Australia. DESIGN: Cross sectional observational design. METHODS: Participants comprised children from four local organised sports clubs in suburban Adelaide, South Australia. The sports examined were Australian Rules Football (AFL), girls' netball, boys' soccer and girls' soccer. Each participant wore a waist-mounted GT3X or GT3X+Actigraph accelerometer in either one or two of the practice sessions. RESULTS: Participants typically spent 40-50% of each sport practice session in moderate to vigorous physical activity (MVPA). Participants in the boys' soccer teams spent significantly greater time in MVPA (mean=47% of practice time, 95% CI=37%, 57%) than participants in the girls' netball teams (mean=40%, 95% CI=30%, 50%), participants in the girls' soccer teams (mean=38%, 95% CI=28%, 48%) and participants in the boys' AFL teams (mean=40%, 95% CI=36%, 44%). The practice sessions contributed approximately half of the 60min of MVPA per day recommended by physical activity guidelines for children and young people. CONCLUSIONS: The results suggested that organised sports provide a supportive environment for physical activity accrual; however, one practice session is insufficient for children to reach the amount of MVPA recommended in daily physical activity guidelines. PMID- 29452750 TI - [Consequences of chronic pain in childhood and adolescence]. AB - OBJECTIVE: Our aim was to examine and map the consequences of chronic pain in children and adolescents. METHOD: A scoping review was carried out in the international databases (PubMed, SCOPUS, WOS and CINAHL, Cochrane Library) and gray literature. We included documents that addressed psychosocial aspects that influence chronic pain, published in English between 2010 and 2016. We excluded the documents that dealt with pharmacological treatments, chronic pain derived from surgical interventions or where there was no access to full text. 34 of the 716 documents reviewed were included. RESULTS: Studies show that pain is associated with high rates of functional disability, sleep disorders and spectrum depression-anxiety. Young people experience higher rates of victimization and stigmatization, contributing to social isolation, difficulty in meeting academic demands and less opportunity to consume illegal substances. With respect to the family, chronic pain has been associated with poorer family functioning and considerable investment of economic resources. CONCLUSIONS: This Scoping Review shows that functional capacity, sleep, personal development, peer support and family functioning are interesting lines in published works. However, gaps in knowledge are detected in areas such as risk behaviours, the consequences that pain can cause in adulthood and gender inequalities. PMID- 29452751 TI - Trends in cancer mortality in Spain: the influence of the financial crisis. AB - OBJECTIVE: To determine if the onset of the economic crisis in Spain affected cancer mortality and mortality trends. METHOD: We conducted a longitudinal ecological study based on all cancer-related deaths and on specific types of cancer (lung, colon, breast and prostate) in Spain between 2000 and 2013. We computed age-standardised mortality rates in men and women, and fit mixed Poisson models to analyse the effect of the crisis on cancer mortality and trends therein. RESULTS: After the onset of the economic crisis, cancer mortality continued to decline, but with a significant slowing of the yearly rate of decline (men: RR = 0.987, 95%CI = 0.985-0.990, before the crisis, and RR = 0.993, 95%CI = 0.991-0.996, afterwards; women: RR = 0.990, 95%CI = 0.988-0.993, before, and RR = 1.002, 95%CI = 0.998-1.006, afterwards). In men, lung cancer mortality was reduced, continuing the trend observed in the pre-crisis period; the trend in colon cancer mortality did not change significantly and continued to increase; and the yearly decline in prostate cancer mortality slowed significantly. In women, lung cancer mortality continued to increase each year, as before the crisis; colon cancer continued to decease; and the previous yearly downward trend in breast cancer mortality slowed down following the onset of the crisis. CONCLUSIONS: Since the onset of the economic crisis in Spain the rate of decline in cancer mortality has slowed significantly, and this situation could be exacerbated by the current austerity measures in healthcare. PMID- 29452752 TI - Mental health, family roles and employment status inside and outside the household in Spain. AB - OBJECTIVE: To document the prevalence of poor mental health by gender and social class, and to analyze if poor mental health is associated with the family roles or the employment status inside and outside the household. METHOD: A cross sectional study based on a representative sample of the Spanish population was carried out (n = 14,247). Mental health was evaluated using GHQ-12. Employment status, marital status, family roles (main breadwinner and the person who mainly carries out the household work) and educational level were considered as explanatory variables. Multiple logistic regression models stratified by gender and social class were fitted and adjusted odds ratios (aOR) were obtained. RESULTS: Gender and social class differences in the prevalence of poor mental health were observed. Unemployment was associated with higher prevalence. Among men the main breadwinner role was related to poor mental health mainly in those that belong to manual classes (aOR = 1.2). Among women, mainly among nonmanual classes, these problems were associated to marital status: widowed, separated or divorced (aOR = 1.9) and to dealing with the household work by themselves (aOR = 1.9). CONCLUSIONS: In Spain, gender and social class differences in mental health still exist. In addition, family roles and working situation, both inside and outside the household, could constitute a source of inequalities in mental health. PMID- 29452753 TI - [Dual approach for atypical atrial flutter ablation after the Mustard procedure]. PMID- 29452754 TI - Insulinoma: A retrospective study analyzing the differences between benign and malignant tumors. AB - BACKGROUND/OBJECTIVES: Insulinoma is a rare pancreatic tumor and, usually, a benign disease but can be a malignant one and, sometimes, a highly aggressive disease. The aim of this study was to determine differences between benign and malignant tumors. METHODS: Retrospective study of 103 patients with insulinoma treated in a tertiary center. It was analyzed demographic, clinical, laboratory, localization and histologic analysis of tumor and follow up data of subjects in order to identify differences between individuals benign and malignant disease. RESULTS: Almost all patients (87%) had a benign tumor and survival rates of 100% following pancreatic tumor surgery. Those with malignant tumors (13%) have a poor prognosis, 77% insulinoma-related deaths over a period of 1-300 months after the diagnosis with a survival rate of 24% in five years. The following factors are associated with an increased risk of malignant disease: duration of symptoms < 24 months, fasting time for the occurrence of hypoglycemia < 8 h, blood plasma insulin concentration >= 28 MUU/mL and C-peptide >= 4.0 ng/mL at the glycemic nadir and tumor size >= 2.5 cm. CONCLUSIONS: Our data help to base the literature about these tumors, reinforcing that although insulinoma is usually a single benign and surgically treated neoplasia, the malignant one is difficult to treat. We highlight the data that help predict a malignancy behavior of tumor and suggest a long follow up after diagnosis in these cases. PMID- 29452755 TI - Machine learning algorithms based on signals from a single wearable inertial sensor can detect surface- and age-related differences in walking. AB - The aim of this study was to investigate if a machine learning algorithm utilizing triaxial accelerometer, gyroscope, and magnetometer data from an inertial motion unit (IMU) could detect surface- and age-related differences in walking. Seventeen older (71.5 +/- 4.2 years) and eighteen young (27.0 +/- 4.7 years) healthy adults walked over flat and uneven brick surfaces wearing an inertial measurement unit (IMU) over the L5 vertebra. IMU data were binned into smaller data segments using 4-s sliding windows with 1-s step lengths. Ninety percent of the data were used as training inputs and the remaining ten percent were saved for testing. A deep learning network with long short-term memory units was used for training (fully supervised), prediction, and implementation. Four models were trained using the following inputs: all nine channels from every sensor in the IMU (fully trained model), accelerometer signals alone, gyroscope signals alone, and magnetometer signals alone. The fully trained models for surface and age outperformed all other models (area under the receiver operator curve, AUC = 0.97 and 0.96, respectively; p <= .045). The fully trained models for surface and age had high accuracy (96.3, 94.7%), precision (96.4, 95.2%), recall (96.3, 94.7%), and f1-score (96.3, 94.6%). These results demonstrate that processing the signals of a single IMU device with machine-learning algorithms enables the detection of surface conditions and age-group status from an individual's walking behavior which, with further learning, may be utilized to facilitate identifying and intervening on fall risk. PMID- 29452756 TI - Quantification of thrombus formation in malapposed coronary stents deployed in vitro through imaging analysis. AB - Stent thrombosis is a major complication of coronary stent and scaffold intervention. While often unanticipated and lethal, its incidence is low making mechanistic examination difficult through clinical investigation alone. Thus, throughout the technological advancement of these devices, experimental models have been indispensable in furthering our understanding of device safety and efficacy. As we refine model systems to gain deeper insight into adverse events, it is equally important that we continue to refine our measurement methods. We used digital signal processing in an established flow loop model to investigate local flow effects due to geometric stent features and ultimately its relationship to thrombus formation. A new metric of clot distribution on each microCT slice termed normalized clot ratio was defined to quantify this distribution. Three under expanded coronary bare-metal stents were run in a flow loop model to induce clotting. Samples were then scanned in a MicroCT machine and digital signal processing methods applied to analyze geometric stent conformation and spatial clot formation. Results indicated that geometric stent features play a significant role in clotting patterns, specifically at a frequency of 0.6225 Hz corresponding to a geometric distance of 1.606 mm. The magnitude-squared coherence between geometric features and clot distribution was greater than 0.4 in all samples. In stents with poor wall apposition, ranging from 0.27 mm to 0.64 mm maximum malapposition (model of real-world heterogeneity), clots were found to have formed in between stent struts rather than directly adjacent to struts. This early work shows how the combination of tools in the areas of image processing and signal analysis can advance the resolution at which we are able to define thrombotic mechanisms in in vitro models, and ultimately, gain further insight into clinical performance. PMID- 29452757 TI - Exploring novel objective functions for simulating muscle coactivation in the neck. AB - Musculoskeletal modeling allows for analysis of individual muscles in various situations. However, current techniques to realistically simulate muscle response when significant amounts of intentional coactivation is required are inadequate. This would include stiffening the neck or spine through muscle coactivation in preparation for perturbations or impacts. Muscle coactivation has been modeled previously in the neck and spine using optimization techniques that seek to maximize the joint stiffness by maximizing total muscle activation or muscle force. These approaches have not sought to replicate human response, but rather to explore the possible effects of active muscle. Coactivation remains a challenging feature to include in musculoskeletal models, and may be improved by extracting optimization objective functions from experimental data. However, the components of such an objective function must be known before fitting to experimental data. This study explores the effect of components in several objective functions, in order to recommend components to be used for fitting to experimental data. Four novel approaches to modeling coactivation through optimization techniques are presented, two of which produce greater levels of stiffness than previous techniques. Simulations were performed using OpenSim and MATLAB cooperatively. Results show that maximizing the moment generated by a particular muscle appears analogous to maximizing joint stiffness. The approach of optimizing for maximum moment generated by individual muscles may be a good candidate for developing objective functions that accurately simulate muscle coactivation in complex joints. This new approach will be the focus of future studies with human subjects. PMID- 29452758 TI - Supplementation with omega-3 fatty acids and plasma adiponectin in women with polycystic ovary syndrome. AB - OBJECTIVE: To study plasma adiponectin levels in women diagnosed with polycystic ovary syndrome given omega-3 fatty acid supplements. PATIENTS AND METHODS: A study was conducted in 195 women diagnosed with polycystic ovary syndrome treated with omega-3 fatty acids for 12weeks (n=97; groupA) and control women given placebo (n=98, groupB). General characteristics, metabolism, lipid profile, and hormone and adiponectin levels were compared. RESULTS: There were no significant differences between the two groups in general characteristics. No significant differences were also found in hormone, blood glucose, and HOMA levels between the groups. Women in study groupsA andB showed no statistically significant differences in total calorie, carbohydrate, protein, and total fat intake between the baseline and final values. Decreased total cholesterol, low-density lipoprotein, and triglyceride levels were found in groupA women (P<.0001). Mean of adiponectin levels also showed a statistically significant increase after treatment (P<.0001). There were no statistically significant differences in the mean values of the different variables in groupB women. CONCLUSION: Omega-3 fatty acid supplementation for 12weeks caused a significant increase in plasma adiponectin levels in women with polycystic ovary syndrome. PMID- 29452759 TI - Feasibility Study of Weekly Nanoparticle Albumin-Bound Paclitaxel (150 mg/m2) Followed by Fluorouracil, Epirubicin, and Cyclophosphamide Therapy as Neoadjuvant Chemotherapy for HER2-Negative Breast Cancer. AB - BACKGROUND: Although several studies have shown efficacy of nanoparticle albumin bound (nab) paclitaxel use as a neoadjuvant treatment in breast cancer, dosage and schedules were varied or used in combination and the data are still limited for weekly regimens. We evaluated the feasibility of weekly nab-paclitaxel followed by FEC (5-FU [fluorouracil], epirubicin, and cyclophosphamide) treatment feasibility as neoadjuvant chemotherapy for breast cancer. PATIENTS AND METHODS: Thirty-three patients with no previous chemotherapy were enrolled to receive nab paclitaxel 150 mg/m2 the first 3 of 4 weeks (3q4w) followed by FEC as neoadjuvant treatment. The trial was powered for analyses of feasibility. RESULTS: Twenty five patients completed the treatment as per protocol, and the completion rate was 75.8% (95% confidence interval, 59.0-87.2; P = .44). The regimen completion group was younger than those with regimen incompletion (average 45.1 vs. 56.6 years). The pathological complete response (ypT0-is/N0) rate was 30.3% in 33 patients, which was higher in triple-negative patients (58.3%). Grade 3/4 neutropenia was seen in 48.5%, although there was no febrile neutropenia. Grade 3 peripheral neuropathy was seen in 33.3%. CONCLUSION: Our study showed that weekly nab-paclitaxel 150 mg/m2 3q4w followed by FEC as neoadjuvant regimen might be sufficient in efficacy, although with a relatively high severe adverse event occurrence rate.

PMID- 29452763 TI - The predictive role of E/e' on ischemic stroke and atrial fibrillation in Japanese patients without atrial fibrillation. AB - BACKGROUND: The predictive role of E/e' on ischemic stroke (IS) and atrial fibrillation (AF) in Japanese patients without AF are unclear. METHODS AND RESULTS: Shinken database includes all the new patients visiting the Cardiovascular Institute Hospital in Tokyo, Japan. E/e' has been routinely measured since 2007. Patients without AF for whom E/e' was measured at the initial visit between 2007 and 2014 (n=11 477, mean age 57.2 years old, men 59.5%) were divided into E/e' tertiles (<8.04, 8.04-11.00, >11.00). During the mean follow-up period of 1.8 years, 58 IS and 140 new appearances of AF were observed. High E/e' tertile was associated with more prevalence of atherothrombotic risks. The cumulative incidence of IS events and new appearance of AF at 6 years in low, middle, and high E/e' tertiles were 0.5%, 1.4%, and 3.0%/year (log-rank test, p<0.001), and 2.5%, 2.9%, and 4.2%/year (log-rank test, p=0.007), respectively. In multivariate analysis, high E/e' tertile was independently associated with IS (HR, 2.857, 95%CI 1.257-6.495, p=0.012). Although high E/e' tertile was independently associated with new appearance of AF when adjusted for coexistence of atherothrombotic risk factors (HR, 1.694, 95%CI, 1.097-2.616, p=0.017), the association was attenuated after adjustment for left atrial dimension. CONCLUSIONS: E/e' was significantly associated with incidence of IS and new appearance of AF in non-AF patients. PMID- 29452764 TI - The paradox of increased risk of atrial fibrillation following bariatric surgery. PMID- 29452765 TI - Strict sequential catheter ablation strategy targeting the pulmonary veins and superior vena cava for persistent atrial fibrillation. AB - BACKGROUND: An effective catheter ablation strategy, beyond pulmonary vein isolation (PVI), for persistent atrial fibrillation (AF) is necessary. Pulmonary vein (PV)-reconduction also causes recurrent atrial tachyarrhythmias. The effect of the PVI and additional effect of a superior vena cava (SVC) isolation (SVCI) was strictly evaluated. METHODS: Seventy consecutive patients with persistent AF who underwent a strict sequential ablation strategy targeting the PVs and SVC were included in this study. The initial ablation strategy was a circumferential PVI. A segmental SVCI was only applied as a repeat procedure when patients demonstrated no PV-reconduction. RESULTS: After the initial procedure, persistent AF was suppressed in 39 of 70 (55.7%) patients during a median follow-up of 32 months. After multiple procedures, persistent AF was suppressed in 46 (65.7%) and 52 (74.3%) patients after receiving the PVI alone and PVI plus SVCI strategies, respectively. In 6 of 15 (40.0%) patients with persistent AF resistant to PVI, persistent AF was suppressed. The persistent AF duration independently predicted persistent AF recurrences after multiple PVI alone procedures [HR: 1.012 (95% confidence interval: 1.006-1.018); p<0.001] and PVI plus SVCI strategies [HR: 1.018 (95% confidence interval: 1.011-1.025); p<0.001]. A receiver-operating characteristic analysis for recurrent persistent AF indicated an optimal cut-off value of 20 and 32 months for the persistent AF duration using the PVI alone and PVI plus SVCI strategies, respectively. CONCLUSIONS: The outcomes of the PVI plus SVCI strategy were favorable for patients with shorter persistent AF durations. The initial SVCI had the additional effect of maintaining sinus rhythm in some patients with persistent AF resistant to PVI. PMID- 29452767 TI - Uptake and distribution of organo-iodine in deep-sea corals. AB - Understanding iodine concentration, transport, and bioavailability is essential in evaluating iodine's impact to the environment and its effectiveness as an environmental biogeotracer. While iodine and its radionuclides have proven to be important tracers in geologic and biologic studies, little is known about transport of this element to the deep sea and subsequent uptake in deep-sea coral habitats. Results presented here on deep-sea black coral iodine speciation and iodine isotope variability provides key information on iodine behavior in natural and anthropogenic environments, and its geochemical pathway in the Gulf of Mexico. Organo-iodine is the dominant iodine species in the black corals, demonstrating that binding of iodine to organic matter plays an important role in the transport and transfer of iodine to the deep-sea corals. The identification of growth bands captured in high-resolution scanning electron images (SEM) with synchronous peaks in iodine variability suggest that riverine delivery of terrestrial-derived organo-iodine is the most plausible explanation to account for annual periodicity in the deep-sea coral geochemistry. Whereas previous studies have suggested the presence of annual growth rings in deep-sea corals, this present study provides a mechanism to explain the formation of annual growth bands. Furthermore, deep-sea coral ages based on iodine peak counts agree well with those ages derived from radiocarbon (14C) measurements. These results hold promise for developing chronologies independent of 14C dating, which is an essential component in constraining reservoir ages and using radiocarbon as a tracer of ocean circulation. Furthermore, the presence of enriched 129I/127I ratios during the most recent period of skeleton growth is linked to nuclear weapons testing during the 1960s. The sensitivity of the coral skeleton to record changes in surface water 129I composition provides further evidence that iodine composition and isotope variability captured in proteinaceous deep-sea corals is a promising geochronometer as well as an emerging tracer for continental material flux. PMID- 29452766 TI - Traumatic stress and accelerated DNA methylation age: A meta-analysis. AB - BACKGROUND: Recent studies examining the association between posttraumatic stress disorder (PTSD) and accelerated aging, as defined by DNA methylation-based estimates of cellular age that exceed chronological age, have yielded mixed results. METHODS: We conducted a meta-analysis of trauma exposure and PTSD diagnosis and symptom severity in association with accelerated DNA methylation age using data from 9 cohorts contributing to the Psychiatric Genomics Consortium PTSD Epigenetics Workgroup (combined N = 2186). Associations between demographic and cellular variables and accelerated DNA methylation age were also examined, as was the moderating influence of demographic variables. RESULTS: Meta-analysis of regression coefficients from contributing cohorts revealed that childhood trauma exposure (when measured with the Childhood Trauma Questionnaire) and lifetime PTSD severity evidenced significant, albeit small, meta-analytic associations with accelerated DNA methylation age (ps = 0.028 and 0.016, respectively). Sex, CD4T cell proportions, and natural killer cell proportions were also significantly associated with accelerated DNA methylation age (all ps < 0.02). PTSD diagnosis and lifetime trauma exposure were not associated with advanced DNA methylation age. There was no evidence of moderation of the trauma or PTSD variables by demographic factors. CONCLUSIONS: Results suggest that traumatic stress is associated with advanced epigenetic age and raise the possibility that cells integral to immune system maintenance and responsivity play a role in this. This study highlights the need for additional research into the biological mechanisms linking traumatic stress to accelerated DNA methylation age and the importance of furthering our understanding of the neurobiological and health consequences of PTSD. PMID- 29452769 TI - The Radiation Resistance of Human Multipotent Mesenchymal Stromal Cells Is Independent of Their Tissue of Origin. AB - PURPOSE: Human mesenchymal stromal cells (MSCs) may aid the regeneration of ionizing radiation (IR)-induced tissue damage. They can be harvested from different tissues for clinical purposes; however, the role of the tissue source on the radiation response of human MSCs remains unknown. METHODS AND MATERIALS: Human MSCs were isolated from adipose tissue, bone marrow, and umbilical cord, and cellular survival, proliferation, and apoptosis were measured after irradiation. The influence of IR on the defining functions of MSCs was assessed, and cell morphology, surface marker expression, and the differentiation potential were examined. Western blot analyses were performed to assess the activation of DNA damage signaling and repair pathways. RESULTS: MSCs from adipose tissue, bone marrow, and umbilical cord exhibited a relative radioresistance independent of their tissue of origin. Defining properties including cellular adhesion and surface marker expression were preserved, and irradiated MSCs maintained their potential for multilineage differentiation irrespective of their tissue source. Analysis of activated DNA damage recognition and repair pathways demonstrated an efficient repair of IR-induced DNA double-strand breaks in MSCs from different tissues, thereby influencing the induction of apoptosis. CONCLUSIONS: These data show for the first time that MSCs are resistant to IR and largely preserve their defining functions after irradiation irrespective of their tissue of origin. Efficient repair of IR-induced DNA double-strand breaks and consecutive reduction of apoptosis induction may contribute to the tissue-independent radiation resistance of MSCs. PMID- 29452768 TI - Qualitative study of challenges of caring for a person with heart failure. AB - Heart failure (HF) is a chronic health condition that causes significant morbidity among older adults, many of whom receive support and care from an informal caregiver. Caregiving is a difficult role with many responsibilities and challenges. An in-depth understanding of these challenges is necessary to develop services, resources, and interventions for HF caregivers. The goal of this study was to qualitatively ascertain the most significant challenges facing HF caregivers. We conducted semi-structured interviews with 16 caregivers of a person with HF (PHF). Content analysis revealed challenges rooted within the PHF (negative affect, resistant behavior, independence, and illness) Caregiver (balancing employment, lack of support, time, and caregiver health) and Relational level (PHF/caregiver dyadic relationship and other relationships). These findings can be used to inform interventions and support services for HF caregivers. PMID- 29452770 TI - Single-Arm Phase 2 Trial of Elective Nodal Dose Reduction for Patients With Locoregionally Advanced Squamous Cell Carcinoma of the Head and Neck. AB - PURPOSE: To evaluate a novel chemoradiation therapy (CRT) regimen for patients with squamous cell carcinoma of the head and neck (SCCHN) incorporating a lower intensity modulated radiation therapy dose to electively treated neck lymph nodes than is currently standard. METHODS AND MATERIALS: Eligible patients had locally advanced SCCHN of the oral cavity, oropharynx, larynx, or hypopharynx. The 7-week CRT course consisted of weekly cisplatin at 35 mg/m2 concurrently with sequential boost intensity modulated radiation therapy: 36 Gy to high- and low-risk planning target volumes followed by a sequential boost to the high-risk planning target volume to 70 Gy. The primary endpoint was elective nodal failure. Secondary endpoints were survival, toxicity, feeding tube duration, and quality of life evaluated by the FACT-HN and QOL-RTI surveys. RESULTS: Between 2011 and 2014, 54 patients were enrolled, 31 (57%) of whom had human papillomavirus (HPV)-positive disease. Of the patients, 35 (65%) had stage IVa disease. The median follow-up period for survivors was 36 months (range, 12-66 months). Elective nodal failure did not develop in any patient. The actuarial 3-year survival rate for the entire cohort was 91% (95% confidence interval [CI] 0.79-0.96); for the HPV-negative group, 85% (95% CI 0.61-0.95); and for the HPV-positive group, 96% (95% CI 0.77 0.99). Common grade 3 toxicities were dysphagia (79%), mucositis and/or stomatitis (41%), nausea (20%), xerostomia (13%), vomiting (11%), and neutropenia (10%). The median feeding tube duration was 142 days. Patient FACT-HN scores were higher at 3, 6, and 12 months versus at the end of treatment (P < .0001). Total FACT-HN scores returned to pretreatment baseline by 6 months. Overall QOL-RTI scores were lower from pretreatment to the end of treatment through 12 months (P = .0001). CONCLUSIONS: This CRT regimen for patients with advanced SCCHN demonstrated the potential feasibility of reducing the elective dose to the neck, a topic that requires additional study in future clinical trials. PMID- 29452771 TI - Radiation Therapy as an Effective Salvage Strategy for Secondary CNS Lymphoma. AB - PURPOSE: We assessed the efficacy of radiation therapy (RT) in the management of secondary central nervous system (CNS) lymphoma. METHODS AND MATERIALS: The cohort comprised 44 patients with systemic diffuse large B-cell lymphoma (DLBCL) secondarily involving the brain and/or leptomeninges at initial diagnosis or relapse that was treated with RT. RESULTS: Of these patients, 29 (66%) were in systemic remission when CNS disease was diagnosed. The overall response rate to RT by magnetic resonance imaging was 88% (42% complete, 46% partial). The median overall survival (OS) after RT initiation was 7 months (95% confidence interval 4 10 months). The OS curve plateaued at 31% from 2 to 8 years. OS was superior in patients who achieved a complete or partial response to RT, underwent stem cell transplantation after RT, and had brain parenchymal (vs leptomeningeal) disease. Eight cases of CNS disease progression occurred after RT: 1 involved the brain parenchyma, and 7 involved the spine and/or cerebrospinal fluid and/or meninges. CONCLUSIONS: We conclude that RT is associated with high response rates and may contribute to long-term OS. In addition, RT may provide CNS disease control that facilitates successful salvage with stem cell transplantation in patients with chemotherapy-refractory disease. PMID- 29452772 TI - Metabolic and Lipidomic Reprogramming in Renal Cell Carcinoma Subtypes Reflects Regions of Tumor Origin. AB - BACKGROUND: Renal cell carcinoma (RCC) consists of prognostic distinct subtypes derived from different cells of origin (eg, clear cell RCC [ccRCC], papillary RCC [papRCC], and chromophobe RCC [chRCC]). ccRCC is characterized by lipid accumulation and metabolic alterations, whereas data on metabolic alterations in non-ccRCC are limited. OBJECTIVE: We assessed metabolic alterations and the lipid composition of RCC subtypes and ccRCC-derived metastases. Moreover, we elucidated the potential of metabolites/lipids for subtype classification and identification of therapeutic targets. DESIGN, SETTING, AND PARTICIPANTS: Metabolomic/lipidomic profiles were quantified in ccRCC (n=58), chRCC (n=19), papRCC (n=14), corresponding nontumor tissues, and metastases (n=9) through a targeted metabolomic approach. Transcriptome profiling was performed in corresponding samples and compared with expression data of The Cancer Genome Atlas cohorts (patients with ccRCC, n=452; patients with papRCC, n=260; and patients with chRCC, n=59). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: In addition to cluster analyses, metabolomic/transcriptomic data were analyzed to evaluate metabolic differences of ccRCC and chRCC using Welch's t test or paired t test as appropriate. Where indicated, p values were adjusted for multiple testing using Bonferroni or Benjamini-Hochberg correction. RESULTS AND LIMITATIONS: Based on their metabolic profiles, RCC subtypes clustered into two groups separating ccRCC and papRCC from chRCC, which mainly reflected the different cells of origin. ccRCC-derived metastases clustered with primary ccRCCs. In addition to differences in certain lipids (lysophosphatidylcholines and sphingomyelins), the coregulation network of lipids differed between ccRCC and chRCC. Consideration of metabolic gene expression indicated, for example, alterations of the polyamine pathway at metabolite and transcript levels. In vitro treatment of RCC cells with the ornithine-decarboxylase inhibitor difluoromethylornithine resulted in reduced cell viability and mitochondrial activity. Further evaluation of clinical utility was limited by the retrospective study design and cohort size. CONCLUSIONS: In summary, we provide novel insight into the metabolic profiles of ccRCC and non ccRCC, thereby confirming the different ontogeny of RCC subtypes. Quantification of differentially regulated metabolites/lipids improves classification of RCC with an impact on the identification of novel therapeutic targets. PATIENT SUMMARY: Several subtypes of renal cell carcinoma (RCC) with different metastatic potentials and prognoses exist. In the present study, we provide novel insight into the metabolism of these different subtypes, which improves classification of subtypes and helps identify novel targets for RCC therapy.

PMID- 29452774 TI - Dietary zinc intake and whole blood zinc concentration in subjects with type 2 diabetes versus healthy subjects: A systematic review, meta-analysis and meta regression. AB - The aim of this systematic review, meta-analysis and meta-regression was to examine the relationship between type 2 diabetes mellitus (T2DM) and concentration of zinc in whole blood, as well as dietary zinc intake. Searches were performed using Ovid MEDLINE, Embase (Ovid) and The Cochrane Library (CENTRAL). Observational studies conducted on diabetic and healthy adults, with data on dietary zinc intake and/or concentration of zinc in whole blood, were selected. The search strategy yielded 11,150 publications and the manual search 6, of which 11 were included in the meta-analyses. Mean difference (MD) and 95% confidence interval (CI), were calculated using the generic inverse-variance method with random-effects models. Heterogeneity was assessed by the Cochran Q statistic and quantified by the I2 statistic. Meta-regressions and stratified analysis were used to examine whether any covariate had influence on the results. The pooled MD for the dietary zinc intake meta-analysis was -0.40 (95% CI: -1.59 to 0.79; I2 = 61.0%). Differences between diabetic and non-diabetic subjects became significant in the presence of complications associated with diabetes (MD = -2.26; 95% CI: -3.49 to -1.02; I2 = 11.9%). Meta-regression showed that for each year since the diagnosis of diabetes the concentration of zinc in whole blood decreased in diabetic patients regarding healthy controls [MD (concentration of zinc in blood) = 732.61 + (-77.88303) * (duration of diabetes in years)], which is not generally explained by a lower intake of zinc. PMID- 29452775 TI - The link between depression and atherosclerosis through the pathways of inflammation and endothelium dysfunction. AB - A large body of evidence suggests that depression increases the risk of cardiovascular morbidity and mortality. The elevated risk associated with depression is not limited to clinical major depressive disorder but also extends to sub-syndromal depressive symptoms and constructs with overlapping characteristics, such as vital exhaustion. Multiple pathophysiological pathways are involved in the relationship between depressive symptoms and atherosclerosis and its clinical manifestations and progression. These underlying mechanisms are not yet fully understood and need further clarification. This review examines inflammation and endothelium dysfunction as potential biological factors involved in the relationship between depressive symptoms and atherosclerosis. It has been reported that systemic inflammation and psychological factors interact through complex pathophysiological and behavioral mechanisms and one question that has been raised concerns whether the inflammation drives depression or vice versa, or whether the association is merely coincidental. Although further investigation is needed, including well-designed prospective studies, to address this question thoroughly, it seems that there is a feedback relationship, although the biological pathways of each direction may be distinct. PMID- 29452776 TI - Women-specific risk factors for heart failure: A genetic approach. AB - Heart failure is a complex disease, which is presented differently by men and women. Several studies have shown that reproductive factors, such as age at natural menopause, parity and polycystic ovarian syndrome (PCOS), may play a role in the development of heart failure. Shared genetics may provide clues to underlying mechanisms; however, this has never been examined. Therefore, the aim of the current study was to explore whether any reproductive factor is potentially related to heart failure in women, based on genetic similarities. Conducting a systematic literature review, single nucleotide polymorphisms (SNPs) associated with reproductive factors, heart failure and its risk factors were extracted from recent genome-wide association studies. We tested whether there was any overlap between the SNPs and their proxies of reproductive risk factors with those known for heart failure or its risk factors. In total, 520 genetic variants were found that are associated with reproductive factors, namely age at menarche, age at natural menopause, menstrual cycle length, PCOS, preeclampsia, preterm delivery and spontaneous dizygotic twinning. For heart failure and associated phenotypes, 25 variants were found. Genetic variants for reproductive factors did not overlap with those for heart failure. However, age at menarche, gestational diabetes and PCOS were found to be genetically linked to risk factors for heart failure, such as atrial fibrillation, diabetes and smoking. Corresponding implicated genes, such as TNNI3K, ErbB3, MKL2, MTNR1B and PRKD1, may explain the associations between reproductive factors and heart failure. Exact effector mechanisms of these genes remain to be investigated further. PMID- 29452777 TI - Yoga for menopausal symptoms-A systematic review and meta-analysis. AB - OBJECTIVES: To systematically review and meta-analyze the effectiveness of yoga for menopausal symptoms. METHODS: Medline (via PubMed), the Cochrane Central Register of Controlled Trials, and Scopus were screened through to February 21, 2017 for randomized controlled trials (RCTs) comparing the effects of yoga on menopausal symptoms to those of no treatment or active comparators. Standardized mean differences (SMD) and 95% confidence intervals (CI) were calculated. Two authors independently assessed risk of bias using the Cochrane risk of bias tool. RESULTS: Thirteen RCTs with 1306 participants were included. Compared with no treatment, yoga reduced total menopausal symptoms (SMD=-1.05; 95% CI -1.57 to 0.53), psychological (SMD=-0.75; 95% CI -1.17 to -0.34), somatic (SMD=-0.65; 95% CI -1.05 to -0.25), vasomotor (SMD=-0.76; 95% CI -1.27 to -0.25), and urogenital symptoms (SMD=-0.53; 95% CI -0.81 to -0.25). Compared with exercise controls, only an effect on vasomotor symptoms was found (SMD=-0.45; 95% CI -0.87 to 0.04). Effects were robust against selection bias, but not against detection and attrition bias. No serious adverse events were reported. CONCLUSION: Yoga seems to be effective and safe for reducing menopausal symptoms. Effects are comparable to those of other exercise interventions. PMID- 29452778 TI - Reproductive history and physical functioning in midlife: The Bogalusa Heart Study. AB - OBJECTIVE: To examine the relationship between reproductive history, pregnancy complications, and later physical function. STUDY DESIGN: The Bogalusa Heart Study is a long-running study of cardiovascular health in a semirural community. 761 women were interviewed about their pregnancy history and complications, and underwent tests of physical function. Logistic models for dichotomous outcomes and linear models for continuous outcomes were used, adjusted for covariates. MAIN OUTCOME MEASURES: Overall scores on the Short Physical Performance Battery (SPPB), which combines scores for balance, gait speed, and chair stands. Additional tests were a 6-min walk, knee extension strength, grip strength, and a pegboard challenge. RESULTS: Nulliparity was associated with lower scores on the walking and balance portions of the SPPB, less distance covered in the 6-min walk, less knee and grip strength, and higher pegboard time, especially among pre menopausal women. A history of gestational diabetes was associated with more problems on the walk portion of the SPPB (aOR 2.44, 1.06-5.65), higher chair stand time, and lower knee strength. Young age at first birth (<16 or 18 years) was associated with a shorter chair stand time and a better pegboard score. CONCLUSIONS: Nulliparity was associated with worse physical functioning, while high parity and early pregnancy were not, suggesting that fertility is associated with better health later in life. Pregnancy complications were associated with worse physical functioning, even after controlling for body mass index. Future studies should attempt to establish the pathways by which reproductive health relates to overall physical functioning. PMID- 29452779 TI - Management of female stress urinary incontinence: A care pathway and update. AB - Stress urinary incontinence (SUI) is a condition characterized by an involuntary loss of urine occurring as result of an increase in intra-abdominal pressure due to effort or exertion or on sneezing or coughing. Estimates of its prevalence in the female population range from 10% to 40%. A literature search of the Medline, Cochrane library, EMBASE, NLH, ClinicalTrials.gov and Google Scholar databases was done up to July 2017, restricted to English-language articles, using terms related to SUI, medical therapy, surgical therapy and treatment options. The search terms included female stress urinary incontinence, mid-urethral sling, tension-free vaginal tape (TVT) and transobturator tape (TOT, TVT-O). Original articles, reviews and meta-analyses were included. Surgical therapy should be considered only after conservative therapies (e.g. an exercise programme or topical estrogens) have failed. Synthetic mid-urethral slings are the gold standard for the surgical treatment of SUI according to the 2016 guidelines of the European Society of Urology (ESU) and the 2017 position statement of the European Urogynaecological Association (EUA). The therapeutic options are numerous but further research into new therapeutic strategies is needed to achieve a better balance between efficacy and adverse events. PMID- 29452780 TI - Gender differences in the association of cognitive impairment with the risk of hip fracture in the older population. AB - OBJECTIVES: To test the hypothesis that differences by gender will be observed in the association of hip fracture risk with stages of cognitive impairment; and to explore the association between Petersen's "mild cognitive impairment" (MCI) and DSM-5 "mild neurocognitive disorder" (MND). STUDY DESIGN: A community sample of 4803 individuals aged 55+ years was assessed in a two-phase case-finding enquiry in Zaragoza, Spain, and was followed up for 16 years. Medical and psychiatric history was collected with standardized instruments, including the Mini-Mental Status Examination (MMSE), Geriatric Mental State (GMS), History and Aetiology Schedule, and a Risk Factors Questionnaire. The statistical analysis included calculations of Hazard Ratios (HR) in multivariate Cox proportional hazards regression models. MAIN OUTCOME MEASURES: Identified cases of hip fracture, validated by blind researchers. RESULTS: In men, hip fracture risk was increased at the "mild" (HR=4.99 (1.39-17.91)) and at the "severe" (HR=9.31 (1.35-64.06)) stages of cognitive impairment, indicated by MMSE performance. In contrast, in women no association could be documented at the "mild stage" (power=89%), and the association disappeared altogether at the "severe stage" in the final multivariate statistical model (power 100%). No association observed between hip fracture and mild cognitive impairment in both men (power=28% for P-MCI) and women (power=44% and 19% for Petersen's MCI and DSM-5 MND, respectively). CONCLUSIONS: Increased hip fracture risk was associated with "mild" stages of cognitive impairment in men, but not in women. To explore the potential association with the construct MCI or MND, studies with greater statistical power would be required. PMID- 29452781 TI - Physical training maintains or improves gait ability in long-term nursing home residents: A systematic review of randomized controlled trials. AB - Numerous studies have reported the benefits of physical exercise in older adults. However, studies performed in long-term nursing home (LTNH) residents are scarce. A literature search was conducted to identify physical exercise intervention studies that were randomized and controlled and that assessed gait ability in older LTNH residents using both walking speed and timed up-and-go (TUG) tests simultaneously. Together, these tests have been defined under the term "gait ability"; they are widely used to screen for impaired physical function, and can predict accelerated functional decline, difficulty with activities of daily living (ADL), falls, and disability in older adults. Multicomponent physical exercise programs are effective in improving or maintaining gait ability in older LTNH residents. The studies included in this review show substantial heterogeneity in terms of participant characteristics (age, baseline TUG performance, and walking speed), types of evaluated intervention (multicomponent and gait retraining programs), duration of the intervention (ranging from four weeks to 12 months), duration of physical exercise sessions (ranging from 30 min to 1 h), and exercise intensity (from 40% to 60-70% RM). Due to this heterogeneity, no firm conclusions can be drawn regarding the impact of exercise programs on gait ability in LTNH residents. However, the results of this review should encourage the gathering of additional evidence to support the use of multicomponent exercise programs by older individuals. PMID- 29452782 TI - Multimorbidity and quality of life at mid-life: A systematic review of general population studies. AB - There is substantial multimorbidity at mid-life but little is known about the strength of evidence on multimorbidity and health-related quality of life (HrQoL) at mid-life. This review addresses this gap, focusing on studies of the general population. PubMed, Web of Science, Embase and APA PsycNET databases were screened on 6 March 2017 for original research on multimorbidity and HrQoL in adults aged 40-65 years from the general population. Studies focused on index conditions, using single-item HrQoL measures, unlikely to represent the general population (e.g. primary care), and papers that were not in the English language were excluded. A narrative synthesis was presented due to heterogeneity in the measurement of multimorbidity. Of the 2557 articles, 83 underwent full text screening and 8 were included in the review. Included studies were of moderate to high quality and no exclusions were made on the basis of quality or bias. Multimorbidity was associated with poorer HrQoL at mid-life. Two cross-sectional studies found that adults with multimorbidity at early mid-life reported poorer HrQoL than adults with multimorbidity at late mid-life, while another found the reverse. Two distinct disease clusters were identified: mental health conditions and cardiovascular disease (CVD). Those in the mental health cluster reported poorer HrQoL than those in the CVD cluster, women more so than men. Limitations of the selected studies include lack of longitudinal evidence, use of self reported conditions and no assessment of disease severity. Multimorbidity is associated with poor HrQoL at mid-life at the population level, with some evidence of differences in association with age and disease cluster and sparse evidence on sex differences. Longitudinal research using a weighted disease severity index and multimorbidity trajectories is needed to strengthen the evidence base. PMID- 29452783 TI - Oxidative stress is increased in sarcopenia and associated with cardiovascular disease risk in sarcopenic obesity. AB - OBJECTIVES: To define whether circulating markers of oxidative stress correlate with sarcopenia in terms of glutathione balance and oxidative protein damage, and whether these biomarkers are associated with risk of cardiovascular disease (CVD). STUDY DESIGN: Population-based cross-sectional study. 115 out of 347 elderly subjects were classified as non-sarcopenic non-obese (NS-NO), sarcopenic non-obese (S-NO), non-sarcopenic obese (NS-O), and sarcopenic obese (S-O). MAIN OUTCOME MEASUREMENTS: Sarcopenia was defined as a relative skeletal muscle mass index (RASM) <7.25kg/m2 for men or <5.67kg/m2 for women, while obesity was diagnosed in those presenting with% fat >27 for men or >38 for women. The CVD risk was estimated by the carotid intima-media thickness (IMT) and the Framingham score. Blood reduced glutathione (GSH), oxidized glutathione (GSSG), plasma malondialdehyde-(MDA) and 4-hydroxy-2,3-nonenal-(HNE) protein adducts were analyzed. RESULTS: Significantly greater blood GSSG/GSH ratio and plasma MDA/HNE protein adducts were observed in sarcopenic than in non-sarcopenic patients. A logistic regression model showed a close relationship between serum HNE and MDA adducts and sarcopenia (OR=1.133, 95% CI 1.057-1.215, and OR=1.592, 95% CI 1.015 1.991, respectively). Linear and logistic regression analysis evidenced strong associations between the IMT or the Framingham CVD risk category and blood GSSG/GSH or serum HNE protein adducts in the S-O group. CONCLUSION: Circulating markers of oxidative stress are increased in sarcopenia and related to CVD risk in sarcopenic obesity, suggesting that redox balance analysis would be a useful part of a multidimensional evaluation in aging. Further research is encouraged to support interventional strategies to correct redox imbalance, which might contribute to the prevention or at least limitation of sarcopenia and its co morbidities. PMID- 29452784 TI - Abdominal aortic aneurysm: Sex differences. AB - OBJECTIVE: Abdominal aortic aneurysm (AAA) predominantly affects an elderly male population. Even so, AAA appears more detrimental in women, who experience a higher risk of aneurysm rupture and a worse outcome after surgery than men. Why women are privileged from yet are worse off once affected has been attributed to an effect of sex hormones. This review summarizes the knowledge of sex differences in AAA and addresses the changes in the aneurysm wall from a gender perspective. METHOD: Standard reporting guidelines set by the PRISMA Group were followed to identify studies examining AAA from a gender perspective. Relevant reports were identified using two electronic databases: PubMed and Web of Science. The systematic search was performed in two stages: firstly, using the terms AAA and gender/sex/women; and secondly, adding the terms "elastin", "collagen" and "vascular smooth muscle cells", in order to filter the search for studies relevant to our focus on the aneurysm wall. CONCLUSION: Current studies support the theory that sex has an effect on aneurysm formation, yet are inconclusive about whether or not aneurysm formation is dependent on female/male sex hormones or a lack thereof. The studies in women are scarce and out of those most reports primarily address other end-points, which limit their ability to illuminate an effect of sex on aneurysm formation. The complexity of the human menstrual cycle and menopausal transition are difficult to mimic in animal models, which limit their applicability to AAA formation in humans. PMID- 29452785 TI - The risks of sarcopenia, falls and fractures in patients with type 2 diabetes mellitus. AB - Fracture risk in patients with type 2 diabetes mellitus (T2DM) is increased, and the mechanism is multifactorial. Recent research on T2DM-induced bone fragility shows that bone mineral density (BMD) is often normal or even slightly elevated. However, bone turnover may be decreased and bone material and microstructural properties are altered, especially when microvascular complications are present. Besides bone fragility, extra-skeletal factors leading to an increased propensity to experience falls may also contribute to the increased fracture risk in T2DM, such as peripheral neuropathy, retinopathy and diabetes medication (e.g. insulin use). One of the probable additional contributing factors to the increased fall and fracture risks in T2DM is sarcopenia, the age-related decline in skeletal muscle mass, quality and function. Although the association between sarcopenia, fall risk, and fracture risk has been studied in the general population, few studies have examined the association between T2DM and muscle tissue and the risks of falls and fractures. This narrative review provides an overview of the literature regarding the multifactorial mechanisms leading to increased fracture risk in patients with T2DM, with a focus on sarcopenia and falls. PMID- 29452786 TI - Preliminary results of a single-arm pilot study to assess the safety and efficacy of visnadine, prenylflavonoids and bovine colostrum in postmenopausal sexually active women affected by vulvovaginal atrophy. AB - This single-arm pilot study enrolled 47 post-menopausal women affected by vulvovaginal atrophy (VVA). The Vaginal Health Index Score (VHIS) was evaluated for all women and all completed the Female Sexual Function Index (FSFI) questionnaire at baseline (T0) and after 15 days of vaginal cream treatment with one application per day (T1). Following treatment there was a significant improvement in all VHIS parameters and total score (p < 0.0001). Similarly, there was a significant improvement on four FSFI domains (lubrication, orgasm, satisfaction and pain) and total score (p = 0.001). None of the patients reported any local or systemic side-effects during treatment. PMID- 29452787 TI - A modelling study to evaluate the costs and effects of lowering the starting age of population breast cancer screening. AB - BACKGROUND: Because the incidence of breast cancer increases between 45 and 50years of age, a reconsideration is required of the current starting age (typically 50years) for routine mammography. Our aim was to evaluate the quantitative benefits, harms, and cost-effectiveness of lowering the starting age of breast cancer screening in the Dutch general population. METHODS: Economic modelling with a lifelong perspective compared biennial screening for women aged 48-74years and for women aged 46-74years with the current Dutch screening programme, which screen women between the ages of 50 and 74years. Tumour deaths prevented, years of life saved (YOLS), false-positive rates, radiation-induced tumours, costs and incremental cost-effectiveness ratios (ICERs) were evaluated. RESULTS: Starting the screening at 48 instead of 50 years of age led to increases in: the number of small tumours detected (4.0%), tumour deaths prevented (5.6%), false positives (9.2%), YOLS (5.6%), radiation-induced tumours (14.7%), and costs (4.1%). Starting the screening at 46 instead of 48 years of age increased the number of small tumours detected (3.3%), tumour deaths prevented (4.2%), false positives (8.8%), YOLS (3.7%), radiation-induced tumours (15.2%), and costs (4.0%). The ICER was ?5600/YOLS for the 48-74 scenario and ?5600/YOLS for the 46 74 scenario. CONCLUSIONS: Women could benefit from lowering the starting age of screening as more breast cancer deaths would be averted. Starting regular breast cancer screening earlier is also cost-effective. As the number of additional expected harms is relatively small in both the scenarios examined, and the difference in ICERs is not large, introducing two additional screening rounds is justifiable. PMID- 29452788 TI - Understanding pre-, peri- and post-menopausal women's intentions to perform muscle-strengthening activities using the Theory of Planned Behaviour. AB - Although physical activity guidelines recommend muscle-strengthening activities (MSA), public health initiatives tend to focus on increasing aerobic activity and fail to mention MSA. This study sought to identify the issues influencing pre-, peri- and post-menopausal women's intentions to perform MSA with a view to informing future interventions for these populations. Mixed methods guided by the Theory of Planned Behaviour (TPB) were used to explore factors that influence women's intentions to perform MSA. In stage one, 34 women participated in either a focus group or interview. Discussions were transcribed verbatim and analysed based on menopausal status using a deductive approach. In stage two, 186 women (M = 47 years, SD = 9) completed a questionnaire to assess participant demographics, levels of MSA, affective and instrumental attitudes, injunctive and descriptive norms, self-efficacy and perceived behavioural control. Quantitative data were analysed using descriptive statistics, bivariate correlations, regression analyses and analysis of variances. Behavioural beliefs were: improved muscular health; psychological benefits; improved body shape. Normative beliefs were: health professionals; family members; work colleagues. Control beliefs were: equipment; motivation; time constraints; knowledge; physical capability; fear of judgement. However, these beliefs were not well established. Self-efficacy was the strongest predictor of intentions (spc2 = 0.11) followed by affective attitudes (spc2 = 0.09), with no significant differences on TPB variables between groups. If rising rates of musculoskeletal conditions in women are to be prevented, there is an urgent need to increase women's knowledge of recommended levels of muscle strengthening, with a view to promoting positive attitudes and enhancing women's sense of self-efficacy across all menopausal phases. PMID- 29452789 TI - Informal caregiving and metabolic markers in the UK Household Longitudinal Study. AB - OBJECTIVES: Informal caregiving is associated with poorer mental and physical health. Little research has yet focused on objectively measured health risk factors, such as metabolic markers. The aim of this study was to investigate whether informal caregiving was associated with markers of metabolism in a large, representative UK longitudinal study. We also investigated whether more intensive caregiving, as indicated by more caregiving hours, was associated with a less favourable metabolic profile. STUDY DESIGN/OUTCOME MEASURES: Using data on 9408 participants aged 16+ from the UK Household Longitudinal Study, we explored the relationship between caregiving and metabolic markers (blood pressure, total and high density lipoprotein cholesterol, glycated haemoglobin and triglycerides). We additionally investigated the importance of caregiving intensity (number of hours spent caregiving per week). Associations between caregiving/caregiving intensity and metabolic markers were tested using gender-stratified linear regression models adjusted for age, household income, education, social class, chronic illness, number of dependent children in the household, body mass index and partnership status. RESULTS: Men who were informal caregivers had higher total cholesterol levels than non-caregivers (3.25% higher, 95% CI: 0.07, 6.53). Women caregivers also had higher total cholesterol levels and women providing intensive care (over 20 h per week) had higher triglyceride levels (19.91% higher, 95% CI: 7.22, 34.10) and lower levels of high density lipoprotein cholesterol (8.46% lower, 95% CI: 14.51, 1.99); however, associations for women were attenuated in our final models. CONCLUSIONS: Informal caregiving is associated with less favourable lipid profiles. This may be one mechanism through which informal caregiving is associated with increased disease risk. The health of informal caregivers should be a priority for public health. PMID- 29452790 TI - [Letter on the article: "Absence of proof does not constitute proof of absence. On the misuse of 'evidence-based medicine'"]. PMID- 29452791 TI - Untapped Reserves: Controlling Primordial Follicle Growth Activation. AB - Even with the benefit of assisted reproductive technologies (ART), many women are unable to conceive and deliver healthy offspring. One common cause of infertility is the inability to produce eggs capable of contributing to live birth. This can occur despite standard-of-care treatment to maximize the recovery of eggs from growing ovarian follicles. Dormant primordial follicles in the human ovary are a 'reserve ' that can be exploited clinically to overcome this problem. We discuss how controlling primordial follicle growth activation (PFGA) can produce increased numbers of high-quality eggs available for fertility treatment(s). We consider the state of the art in interventions used to control PFGA, and consider genetic and epigenetic strategies on the horizon that might improve compromised oocyte quality to increase live births.

PMID- 29452792 TI - Clinical and radiological features of spinal extradural arachnoid cysts: Valve like mechanism involving the nerve root fiber as a possible cause of cyst expansion. AB - BACKGROUND: Although a valve-like mechanism has been proposed for expansion of spinal extradural arachnoid cysts (SEACs), the detailed mechanism remains unclear. Moreover, closure of the communication site is essential during surgery, but the method to identify the communication site remains unclear. The aim of this study was to determine the detailed mechanism of expanding SEACs through retrospective analysis of SEAC cases undergoing surgery and to elucidate the characteristics of the communication sites. METHODS: The authors retrospectively evaluated 12 patients with SEACs who underwent surgery between 2000 and 2014 and analyzed their perioperative findings. RESULTS: Dural defects were detected in 11 out of 12 patients, and a valve-like mechanism was observed in 7 patients, wherein a nerve root fiber moved back and forth through the dural defect along with the flow of cerebrospinal fluid (CSF) between the intradural space and the extradural arachnoid cysts. The dural defect was located at the thoracolumbar junction in 7 patients, below the distal end of the bridging ossification in 2, at the level of vertebral wedge deformity in 2, and at the level of disc herniation in 1. CONCLUSIONS: A valve-like mechanism was observed in 7 of the 12 patients, which suggests that it could serve as a mechanism of SEAC formation. The communication sites were variously located at the end of ossification in patients with diffuse idiopathic skeletal hyperostosis (DISH), wedge deformity of the vertebral body, or disc herniation, indicating the contribution of mechanical stress to SEAC formation.

AB - Intensive-care-unit (ICU) patients exhibit disturbed sleeping patterns, often attributed to environmental noise, although the relative contribution of noise compared to other potentially disrupting factors is often debated. We therefore systematically reviewed studies of the effects of ICU noise on the quality of sleep to determine to what extent noise explains the observed sleep disruption, using the Cochrane Collaboration method for non-randomized studies. Searches in Scopus, PubMed, Embase, CINAHL, Web of Science, and the Cochrane Library were conducted until May 2017. Twenty papers from 18 studies assessing sleep of adult patients and healthy volunteers in the ICU environment, whilst recording sound levels, were included and independently reviewed by two reviewers. We found that the numbers of arousals between the baseline and the ICU noise condition in healthy subjects differed significantly (mean difference 9.59; 95% confidence interval 2.48-16.70). However, there was considerable heterogeneity between studies (I2 94%, P < 0.00001), and all studies suffered from a considerable risk of bias. The meta-analysis of results was hampered by widely varying definitions of sound parameters between studies and a general lack of detailed description of methods used. It is, therefore, currently impossible to quantify the extent to which noise contributes to sleep disruption among ICU patients, and thus, the potential benefit from noise reduction remains unclear. Regardless, the majority of the observed sleep disturbances remain unexplained. Future studies should, therefore, also focus on more intrinsic sleep-disrupting factors in the ICU environment. PMID- 29452802 TI - Moving to human trials for argon neuroprotection in neurological injury: a narrative review. AB - Despite the global burden of brain injury, neuroprotective agents remain elusive. There are no clinically effective therapies which reduce mortality or improve long-term cognitive outcome. Ventilation could be an easily modifiable variable in resuscitation; gases are relatively simple to administer. Xenon is the prototypic agent of a new generation of experimental treatments which show promise. However, use is hindered by its prohibitive cost and anaesthetic properties. Argon is an attractive option, being cheaper, easy to transport, non sedating, and mechanistically distinct from xenon. In vitro and in vivo models provide evidence of argon reducing brain injury, with improvements in neurocognitive, histological, and biomarker metrics, as well as improved survival. Current data suggest that the effect of argon is mediated via the toll like receptors 2 and 4, the extracellular signal-regulated kinase 1/2, and phosphatidylinositol 3 kinase (PI-3K)-AKT pathways. Ventilation with argon appears to be safe in pigs and preliminary human trials. Given recent evidence that arterial hyperoxia may be harmful, the supplementation of high-concentration argon may not necessitate changes to clinical practice. Given the logistic benefits, and the evidence for argon neuroprotection summarized in this manuscript, we believe that the time has come to consider developing Phase II clinical trials to assess its benefit in acute neurological injury. PMID- 29452803 TI - Preoperative fasting in children: review of existing guidelines and recent developments. AB - The current guidelines for preoperative fasting recommend intervals of 6, 4, and 2 h (6-4-2) of fasting for solids, breast milk, and clear fluids, respectively. The objective is to minimize the risk of pulmonary aspiration of gastric contents, but also to prevent unnecessarily long fasting intervals. Pulmonary aspiration is rare and associated with nearly no mortality in paediatric anaesthesia. The incidence may have decreased during the last decades, judging from several audits published recently. However, several reports of very long fasting intervals have also been published, in spite of the implementation of the 6-4-2 fasting regimens. In this review, we examine the physiological basis for various fasting recommendations, the temporal relationship between fluid intake and residual gastric content, and the pathophysiological effects of preoperative fasting, and review recent publications of various attempts to reduce the incidence of prolonged fasting in children. The pros and cons of the current guidelines will be addressed, and possible strategies for a future revision will be suggested. PMID- 29452804 TI - Inter-observer reliability of preoperative cardiopulmonary exercise test interpretation: a cross-sectional study. AB - BACKGROUND: Despite the increasing importance of cardiopulmonary exercise testing (CPET) for preoperative risk assessment, the reliability of CPET interpretation is unclear. We aimed to assess inter-observer reliability of preoperative CPET. METHODS: We conducted a prospective, multi-centre, observational study of preoperative CPET interpretation. Participants were professionals with previous experience or training in CPET, assessed by a standardized questionnaire. Each participant interpreted 100 tests using standardized software. The CPET variables of interest were oxygen consumption at the anaerobic threshold (AT) and peak oxygen consumption (VO2 peak). Inter-observer reliability was measured using intra-class correlation coefficient (ICC) with a random effects model. Results are presented as ICC with 95% confidence interval, where ICC of 1 represents perfect agreement and ICC of 0 represents no agreement. RESULTS: Participants included 8/28 (28.6%) clinical physiologists, 10 (35.7%) junior doctors, and 10 (35.7%) consultant doctors. The median previous experience was 140 (inter quartile range 55-700) CPETs. After excluding the first 10 tests (acclimatization) for each participant and missing data, the primary analysis of AT and VO2 peak included 2125 and 2414 tests, respectively. Inter-observer agreement for numerical values of AT [ICC 0.83 (0.75-0.90)] and VO2 peak [ICC 0.88 (0.84-0.92)] was good. In a post hoc analysis, inter-observer agreement for identification of the presence of a reportable AT was excellent [ICC 0.93 (0.91 0.95)] and a reportable VO2 peak was moderate [0.73 (0.64-0.80)]. CONCLUSIONS: Inter-observer reliability of interpretation of numerical values of two commonly used CPET variables was good (>80%). However, inter-observer agreement regarding the presence of a reportable value was less consistent. PMID- 29452805 TI - Perioperative cardiopulmonary exercise testing (CPET): consensus clinical guidelines on indications, organization, conduct, and physiological interpretation. AB - The use of perioperative cardiopulmonary exercise testing (CPET) to evaluate the risk of adverse perioperative events and inform the perioperative management of patients undergoing surgery has increased over the last decade. CPET provides an objective assessment of exercise capacity preoperatively and identifies the causes of exercise limitation. This information may be used to assist clinicians and patients in decisions about the most appropriate surgical and non-surgical management during the perioperative period. Information gained from CPET can be used to estimate the likelihood of perioperative morbidity and mortality, to inform the processes of multidisciplinary collaborative decision making and consent, to triage patients for perioperative care (ward vs critical care), to direct preoperative interventions and optimization, to identify new comorbidities, to evaluate the effects of neoadjuvant cancer therapies, to guide prehabilitation and rehabilitation, and to guide intraoperative anaesthetic practice. With the rapid uptake of CPET, standardization is key to ensure valid, reproducible results that can inform clinical decision making. Recently, an international Perioperative Exercise Testing and Training Society has been established (POETTS www.poetts.co.uk) promoting the highest standards of care for patients undergoing exercise testing, training, or both in the perioperative setting. These clinical cardiopulmonary exercise testing guidelines have been developed by consensus by the Perioperative Exercise Testing and Training Society after systematic literature review. The guidelines have been endorsed by the Association of Respiratory Technology and Physiology (ARTP). PMID- 29452806 TI - Steroid administration after anaesthetic induction with etomidate does not reduce in-hospital mortality or cardiovascular morbidity after non-cardiac surgery. AB - BACKGROUND: We tested the primary hypothesis that corticosteroid administration after etomidate exposure reduces a composite of in-hospital mortality and cardiovascular morbidity after non-cardiac surgery. METHODS: We evaluated ASA physical status III and IV patients who had non-cardiac surgery with general anaesthesia at the Cleveland Clinic. Amongst 4275 patients in whom anaesthesia was induced with etomidate, 804 were also given steroid intraoperatively, mostly dexamethasone at a median dose of 6 mg. We successfully matched 582 steroid patients with 1023 non-steroid patients. The matched groups were compared on composite of in-hospital mortality and cardiovascular morbidity using a generalized-estimating-equation model. Secondly, the matched groups were compared on length of hospital stay using a Cox proportional hazard model, and were descriptively compared on intraoperative blood pressures using a standardized difference. RESULTS: There was no significant association between intraoperative steroid administration after anaesthetic induction with etomidate and the composite of in-hospital mortality or cardiovascular morbidity; the estimated common odds ratio across the two components of the composite was 0.86 [95% confidence interval (CI): 0.64, 1.16] for steroid vs non-steroid, P=0.33. The duration of postoperative hospitalisation was significantly shorter amongst steroid patients [median (Q1, Q3): 6 (3, 10) days] than non-steroid patients [7 (4, 11) days], with an estimated hazard ratio of 0.89 (0.80, 0.98) for steroid vs non-steroid, P=0.01. Intraoperative blood pressures were similar in steroid and non-steroid patients. CONCLUSIONS: Steroid administration after induction of anaesthesia with etomidate did not reduce mortality or cardiovascular morbidity. PMID- 29452807 TI - Incidence and outcomes of sepsis after cardiac surgery as defined by the Sepsis-3 guidelines. AB - BACKGROUND: The Sepsis-3 guidelines diagnose sepsis based on organ dysfunction in patients with either proven or suspected infection. The objective of this study was to assess the incidence and outcomes of sepsis diagnosed using these guidelines in patients in a cardiac intensive care unit (CICU) after cardiac surgery. METHODS: Daily sequential organ failure assessment (SOFA) scores were calculated for 2230 consecutive adult cardiac surgery patients between January 2013 and May 2015. Patients with an increase in SOFA score of >=2 and suspected or proven infection were identified. The length of CICU stay, 30-day mortality and 2-yr survival were compared between groups. Multivariable linear regression, multivariable logistic regression, and Cox proportional hazards regression were used to adjust for possible confounders. RESULTS: Sepsis with suspected or proven infection was diagnosed in 104 (4.7%) and 107 (4.8%) patients, respectively. After adjustment for confounding variables, sepsis with suspected infection was associated with an increased length of CICU stay of 134.1h (95% confidence interval (CI) 99.0-168.2, P<0.01) and increased 30-day mortality risk (odds ratio 3.7, 95% CI 1.1-10.2, P=0.02). Sepsis with proven infection was associated with an increased length of CICU stay of 266.1h (95% CI 231.6-300.7, P<0.01) and increased 30-day mortality risk (odds ratio 6.6, 95% CI 2.6-15.7, P<0.01). CONCLUSIONS: Approximately half of sepsis diagnoses were based on proven infection and half on suspected infection. Patients diagnosed with sepsis using the Sepsis-3 guidelines have significantly worse outcomes after cardiac surgery. The Sepsis-3 guidelines are a potentially useful tool in the management of sepsis following cardiac surgery. PMID- 29452808 TI - Norepinephrine exerts an inotropic effect during the early phase of human septic shock. AB - BACKGROUND: We conducted this study to investigate whether norepinephrine increases cardiac contractility when administered during the early phase of septic shock. METHODS: We studied 38 patients with septic shock who had been resuscitated for <3 h and whose mean arterial pressure (MAP) remained <65 mm Hg. Echocardiographic variables were obtained before (T0) and after either initiation or an increase in the dose of a norepinephrine infusion to increase MAP to >= 65 mm Hg (T1). We collected left ventricular ejection fraction (LVEF), velocity-time integral of the left ventricular outflow tract (VTI), tissue Doppler imaging of mean systolic velocity of the lateral tricuspid annulus (Sa) and of the lateral mitral annulus (Sm), and tricuspid annular plane systolic excursion (TAPSE). RESULTS: There were significant (P<0.05) increases from T0 to T1 in MAP [mean (sd): from 56 (7) to 80 (9) mm Hg], LVEF [from 49 (13) to 56 (13)%], VTI [from 18 (5) to 20 (6) cm], Sm [from 10.8 (5.1) to 12.1 (5.0) cm s-1], TAPSE [from 1.8 (0.5) to 2.0 (0.5) cm], and Sa [from 13.0 (5.6) to 15.1 (6.4) cm s-1]. In the subgroup of 15 patients with LVEF <=45%, significant increases in VTI [from 16 (8) to 18 (7) cm] and in LVEF [from 36 (7) to 44 (10)%] were observed. CONCLUSIONS: Norepinephrine administration during early resuscitation in patients with septic shock increased the cardiac systolic function despite the presumed increase in left ventricular afterload secondary to the increased arterial pressure. Whether such an effect persists over time remains to be evaluated. CLINICAL TRIAL REGISTRATION: NCT02750683. PMID- 29452809 TI - Test of neural inertia in humans during general anaesthesia. AB - BACKGROUND: Neural inertia is defined as the tendency of the central nervous system to resist transitions between arousal states. This phenomenon has been observed in mice and Drosophila anaesthetized with volatile anaesthetics: the effect-site concentration required to induce anaesthesia in 50% of the population (C50) was significantly higher than the effect-site concentration for 50% of the population to recover from anaesthesia. We evaluated this phenomenon in humans using propofol or sevoflurane (both with or without remifentanil) as anaesthetic agents. METHODS: Thirty-six healthy volunteers received four sessions of anaesthesia with different drug combinations in a step-up/step-down design. Propofol or sevoflurane was administered with or without remifentanil. Serum concentrations of propofol and remifentanil were measured from arterial blood samples. Loss and return of responsiveness (LOR-ROR), response to pain (PAIN), Patient State Index (PSI) and spectral edge frequency (SEF) were modeled with NONMEM(r). RESULTS: For propofol, the C50 for induction and recovery of anaesthesia was not significantly different across the different endpoints. For sevoflurane, for all endpoints except SEF, significant differences were found. For some endpoints (LOR and PAIN) the difference was significant only when sevoflurane was combined with remifentanil. CONCLUSIONS: Our results nuance earlier findings with volatile anaesthetics in mice and Drosophila. Methodological aspects of the study, such as the measured endpoint, influence the detection of neural inertia. A more thorough definition of neural inertia, with a robust methodological framework for clinical studies is required to advance our knowledge of this phenomenon.

AB - BACKGROUND: Perioperative neurocognitive disorders (PND) result in long-term morbidity and mortality with no effective interventions available. Because interleukin-6 (IL-6), a pro-inflammatory cytokine, is consistently up-regulated by trauma, including after surgery, we determined whether IL-6 is a putative therapeutic target for PND in a mouse model. METHODS: Following institutional approval, adult (12-14 weeks) male C57/Bl6 mice were pretreated with the IL-6 receptor (IL6R) blocking antibody tocilizumab prior to open tibia fracture with internal fixation under isoflurane anaesthesia. Inflammatory and behavioural responses in a trace fear conditioning (TFC) paradigm were assessed postoperatively. Separately, the effects of IL-6 administration or of depletion of bone marrow-derived monocytes (BM-DMs) with clodrolip on the inflammatory and behavioural responses were assessed. Blood brain barrier disruption, hippocampal microglial activation, and infiltration of BM-DMs were each assessed following IL 6 administration. RESULTS: The surgery-induced decrement in freezing time in the TFC assay, indicative of cognitive decline, was attenuated by tocilizumab (P<0.01). The surgery-induced increase in pro-inflammatory mediators was significantly reduced by tocilizumab. Exogenously administered IL-6 significantly impaired freezing behaviour (P<0.05) and up-regulated pro-inflammatory cytokines; both responses were prevented by depletion of BM-DMs. IL-6 disrupted the blood brain barrier, and increased hippocampal activation of microglia and infiltration of BM-DMs. CONCLUSIONS: IL-6 is both necessary and sufficient to produce cognitive decline. Following further preclinical testing of its perioperative safety, the IL6R blocker tocilizumab is a candidate for prevention and/or treatment of PND. PMID- 29452811 TI - Effects on adult cognitive function after neonatal exposure to clinically relevant doses of ionising radiation and ketamine in mice. AB - BACKGROUND: Radiological methods for screening, diagnostics and therapy are frequently used in healthcare. In infants and children, anaesthesia/sedation is often used in these situations to relieve the patients' perception of stress or pain. Both ionising radiation (IR) and ketamine have been shown to induce developmental neurotoxic effects and this study aimed to identify the combined effects of these in a murine model. METHODS: Male mice were exposed to a single dose of ketamine (7.5 mg kg-1 body weight) s.c. on postnatal day 10. One hour after ketamine exposure, mice were whole body irradiated with 50-200 mGy gamma radiation (137Cs). Behavioural observations were performed at 2, 4 and 5 months of age. At 6 months of age, cerebral cortex and hippocampus tissue were analysed for neuroprotein levels. RESULTS: Animals co-exposed to IR and ketamine displayed significant (P<=0.01) lack of habituation in the spontaneous behaviour test, when compared with controls and single agent exposed mice. In the Morris Water Maze test, co-exposed animals showed significant (P<=0.05) impaired learning and memory capacity in both the spatial acquisition task and the relearning test compared with controls and single agent exposed mice. Furthermore, in co-exposed mice a significantly (P<=0.05) elevated level of tau protein in cerebral cortex was observed. Single agent exposure did not cause any significant effects on the investigated endpoints. CONCLUSION: Co-exposure to IR and ketamine can aggravate developmental neurotoxic effects at doses where the single agent exposure does not impact on the measured variables. These findings show that estimation of risk after paediatric low-dose IR exposure, based upon radiation dose alone, may underestimate the consequences for this vulnerable population. PMID- 29452812 TI - Randomised trial comparing forced-air warming to the upper or lower body to prevent hypothermia during thoracoscopic surgery in the lateral decubitus position. AB - BACKGROUND: In the supine position, forced-air warming is more effective on the lower body than on the upper body to prevent intraoperative hypothermia. However, it is unknown in the lateral decubitus position. We thus compared forced-air warming on the upper and lower bodies in the lateral position. METHODS: Patients (n=123) were randomised to receive forced-air warming on the upper body or lower body during thoracoscopic surgery in the lateral position. We measured the nasopharyngeal temperature at 0, 30, 60, 90, and 120 min after lateral positioning during surgery and the infrared tympanic membrane temperature at 0, 30, 60, 90, and 120 min after surgery. Patients received both upper and lower body warming at a temperature of <35.5 degrees C. The primary outcome was the incidence of intraoperative hypothermia with a temperature of <36.0 degrees C. RESULTS: Intraoperative hypothermia was less frequent with the upper body warming than with the lower body warming {21/62 vs 35/61, risk ratio [95% confidence interval (CI)] 0.6 (0.4-0.9), P=0.011}. The intraoperative temperature was higher with the upper body warming than with the lower body warming at 30 (P=0.002), 60 (P<0.001), and 90 (P<0.001) min after lateral positioning, and the postoperative temperature was higher at 0 (P<0.001) and 30 (P=0.001) min after surgery. Fewer patients received both upper and lower body warming in the upper body warming group than in the lower body warming group during surgery (1 vs 7, P=0.032). CONCLUSIONS: Forced-air warming was more effective on the upper body than on the lower body to prevent hypothermia during thoracoscopic surgery in the lateral decubitus position.

PMID- 29452813 TI - Incidence, characteristics, and predictive factors for medication errors in paediatric anaesthesia: a prospective incident monitoring study. AB - BACKGROUND: Medication errors are not uncommon in hospitalized patients. Paediatric patients may have increased risk for medication errors related to complexity of weight-based dosing calculations or problems with drug preparation and dilution. This study aimed to determine the incidence of medication errors in paediatric anaesthesia in a university paediatric hospital, and to identify their characteristics and potential predictive factors. METHODS: This prospective incident monitoring study was conducted between November 2015 and January 2016 in an exclusively paediatric surgical centre. Children <18 yr undergoing general anaesthesia were consecutively included. For each procedure, an incident form was completed by the attending anaesthetist on an anonymous and voluntary basis. RESULTS: Incident forms were completed in 1400 (73%) of the 1925 general anaesthetics performed during the study period with 37 reporting at least one medication error (2.6%). Drugs most commonly involved in medication errors were opioids and antibiotics. Incorrect dose was the most frequently reported type of error (n=27, 67.5%), with dilution error involved in 7/27 (26%) cases of incorrect dose. Duration of procedure >120 min was the only factor independently associated with medication error [adjusted odds ratio: 4 (95% confidence interval: 2-8); P=0.0001]. CONCLUSIONS: Medication errors are not uncommon in paediatric anaesthesia. Identification of the mechanisms related to medication errors might allow preventive measures that can be assessed in further studies. PMID- 29452814 TI - Deep or awake removal of laryngeal mask airway in children at risk of respiratory adverse events undergoing tonsillectomy-a randomised controlled trial. AB - BACKGROUND: Laryngeal mask airways (LMA) are widely used during tonsillectomies. Contrasting evidence exists regarding the timing of the removal and the risk of perioperative respiratory adverse events. We assessed whether the likelihood of perioperative respiratory adverse events is influenced by the timing of LMA removal in children with at least one risk factor for these events. METHODS: Participants (n=290, 0-16 yr) were randomised to have their LMA removed either deep (in theatre by anaesthetist at end-tidal sevoflurane >1 minimum alveolar concentration) or awake (in theatre by anaesthetist or in postanaesthesia care unit by anaesthetist or trained nurse). The primary outcome was the occurrence of perioperative respiratory adverse events over the whole emergence and postanaesthesia care unit phases of anaesthesia. The secondary outcome was the occurrence of perioperative respiratory adverse events over the distinct phases of emergence and postanaesthesia care unit. RESULTS: Data from 283 participants were analysed. PRIMARY OUTCOME: even though a higher occurrence of adverse events was observed in the awake group, no evidence for a difference was found [45% vs 35%, odds ratio (OR): 1.5, 95% confidence interval (CI): 0.9-2.5, P=0.09]. Secondary outcome: there was no evidence for a difference between the groups during emergence [19 (14%) deep vs 25 (18%) awake, OR: 0.74, 95%CI: 0.39-1.42, P=0.37]. However, in the postanaesthesia care unit, children with an awake rather than deep removal experienced significantly more adverse events [55 (39%) vs 37 (26%); OR: 1.85, 95%CI: 1.12-3.07, P=0.02]. CONCLUSION: We found no evidence for a difference in the timing of the LMA removal on the incidence of respiratory adverse events over the whole emergence and postanaesthesia care unit phases. However, in the postanaesthesia care unit solely, awake removal was associated with significantly more respiratory adverse events than deep removal.

PMID- 29452815 TI - Variable versus conventional lung protective mechanical ventilation during open abdominal surgery (PROVAR): a randomised controlled trial. AB - BACKGROUND: Experimental studies showed that controlled variable ventilation (CVV) yielded better pulmonary function compared to non-variable ventilation (CNV) in injured lungs. We hypothesized that CVV improves intraoperative and postoperative respiratory function in patients undergoing open abdominal surgery. METHODS: Fifty patients planned for open abdominal surgery lasting >3 h were randomly assigned to receive either CVV or CNV. Mean tidal volumes and PEEP were set at 8 ml kg-1 (predicted body weight) and 5 cm H2O, respectively. In CVV, tidal volumes varied randomly, following a normal distribution, on a breath-by breath basis. The primary endpoint was the forced vital capacity (FVC) on postoperative Day 1. Secondary endpoints were oxygenation, non-aerated lung volume, distribution of ventilation, and pulmonary and extrapulmonary complications until postoperative Day 5. RESULTS: FVC did not differ significantly between CVV and CNV on postoperative Day 1, 61.5 (standard deviation 22.1) % vs 61.9 (23.6) %, respectively; mean [95% confidence interval (CI)] difference, -0.4 (-13.2-14.0), P=0.95. Intraoperatively, CVV did not result in improved respiratory function, haemodynamics, or redistribution of ventilation compared to CNV. Postoperatively, FVC, forced expiratory volume at the first second (FEV1), and FEV1/FVC deteriorated, while atelectasis volume and plasma levels of interleukin-6 and interleukin-8 increased, but values did not differ between groups. The incidence of postoperative pulmonary and extrapulmonary complications was comparable in CVV and CNV. CONCLUSIONS: In patients undergoing open abdominal surgery, CVV did not improve intraoperative and postoperative respiratory function compared with CNV. CLINICAL TRIAL REGISTRATION: NCT 01683578. PMID- 29452816 TI - Transnasal humidified rapid insufflation ventilatory exchange for oxygenation of children during apnoea: a prospective randomised controlled trial. AB - BACKGROUND: Transnasal humidified rapid insufflation ventilatory exchange (THRIVE) comprises the administration of heated, humidified, and blended air/oxygen mixtures via nasal cannula at rates of >=2 litres kg-1 min-1. The aim of this randomized controlled study was to evaluate the length of the safe apnoea time using THRIVE with two different oxygen concentrations (100% vs 30% oxygen) compared with standard low-flow 100% oxygen administration. METHODS: Sixty patients, aged 1-6 yr, weighing 10-20 kg, undergoing general anaesthesia for elective surgery, were randomly allocated to receive one of the following oxygen administration methods during apnoea: 1) low-flow 100% oxygen at 0.2 litres kg-1 min-1; 2) THRIVE 100% oxygen at 2 litres kg-1 min-1; and 3) THRIVE 30% oxygen at 2 litres kg-1 min-1. Primary outcome was time to desaturation to 95%. Termination criteria included SpO2 decreased to 95%, transcutaneous CO2 increased to 65 mmHg, or apnoea time of 10 min. RESULTS: The median (interquartile range) [range] apnoea time was 6.9 (5.7-7.8) [2.8-10.0] min for low-flow 100% oxygen, 7.6 (6.2 9.1) [5.2-10.0] min for THRIVE 100% oxygen, and 3.0 (2.4-3.7) [0.2-5.3] min for THRIVE 30% oxygen. No significant difference was detected between apnoea times with low-flow and THRIVE 100% oxygen administration (P=0.15). THRIVE with 30% oxygen demonstrated significantly shorter apnoea times (P<0.001) than both 100% oxygen modalities. The overall rate of transcutaneous CO2 increase was 0.57 (0.49 0.63) [0.29-8.92] kPa min-1 without differences between the 3 groups (P=0.25). CONCLUSIONS: High-flow 100% oxygen (2 litres kg-1 min-1) administered via nasal cannulas did not extend the safe apnoea time for children weighing 10-20 kg compared with low-flow nasal cannula oxygen (0.2 litres kg-1 min-1). No ventilatory effect was observed with THRIVE at 2.0 litres kg-1 min-1. CLINICAL TRIAL REGISTRATION: NCT02979067.

PMID- 29452829 TI - Cribriform plate width is highly variable within and between subjects. AB - OBJECTIVE: All successful endonasal surgery, including functional endoscopic sinus surgery (FESS), depends on knowledge of both anatomy and the specific variations that can occur between and within patients. Familiarity with these structures is a critical component in preventing complications from these procedures, and failure to understand subtle variation can have disastrous results. The aim of this study was to characterize the anatomical variations (if any) of the cribriform plate using a large cadaveric sample set. Better understanding of the disparities within and between patients may have important implications for surgical planning. METHODS: Whole human skull specimens (31 specimens, 62 sides) were examined to obtain dimensional measurements of the cribriform plate on the right and left sides. RESULTS: The average length of the cribriform plate was 21.28mm (range 15.25-27.73mm, SD 3.30mm). The average width of the cribriform plate (including the crista galli) was 4.53mm (range 1.75 8.03mm, SD 1.20mm). When comparing side differences in individual specimens, there was more variability between widths, relative standard deviation 26.4%, than between lengths, relative standard deviation 15.5%. CONCLUSION: There is a range of both length and width of the cribriform plate, between and within individuals. This is particularly true for width. In practice, this emphasizes the importance of pre-operative imaging and recognition of anatomic variability for sinus or anterior skull base procedure. PMID- 29452828 TI - Glutamatergic Ventral Pallidal Neurons Modulate Activity of the Habenula Tegmental Circuitry and Constrain Reward Seeking. AB - BACKGROUND: The ability to appropriately integrate and respond to rewarding and aversive stimuli is essential for survival. The ventral pallidum (VP) plays a critical role in processing both rewarding and aversive stimuli. However, the VP is a heterogeneous structure, and how VP subpopulations integrate into larger reward networks to ultimately modulate these behaviors is not known. We identify a noncanonical population of glutamatergic VP neurons that play a unique role in responding to aversive stimuli and constraining inappropriate reward seeking. METHODS: Using neurochemical, genetic, and electrophysiological approaches, we characterized glutamatergic VP neurons (n = 4-8 mice/group). We performed patch clamp and in vivo electrophysiology recordings in the lateral habenula, rostromedial tegmental nucleus, and ventral tegmental area to determine the effect of glutamatergic VP neuron activation in these target regions (n = 6-10 mice/group). Finally, we selectively optogenetically stimulated glutamatergic VP neurons in a real-time place preference task and ablated these neurons using a virally expressed caspase to determine their necessity for reward seeking. RESULTS: Glutamatergic VP neurons exhibit little overlap with cholinergic or gamma-aminobutyric acidergic markers, the canonical VP subtypes, and exhibit distinct membrane properties. Glutamatergic VP neurons innervate and increase firing activity of the lateral habenula, rostromedial tegmental nucleus, and gamma-aminobutyric acidergic ventral tegmental area neurons. While nonselective optogenetic stimulation of the VP induced a robust place preference, selective activation of glutamatergic VP neurons induced a place avoidance. Viral ablation of glutamatergic VP neurons increased reward responding and abolished taste aversion to sucrose. CONCLUSIONS: Glutamatergic VP neurons constitute a noncanonical subpopulation of VP neurons. These glutamatergic VP neurons increase activity of the lateral habenula, rostromedial tegmental nucleus, and gamma aminobutyric acidergic ventral tegmental area neurons and adaptively constrain reward seeking. PMID- 29452830 TI - Usefulness of reconstructed 3D images for cochlear implantation in a case with a facial nerve anomaly. AB - Facial nerve anomalies are a potential problem in patients with cochleovestibular malformations. A case of cochlear implant (CI) surgery in the presence of intra temporalbone facial nerve bifurcation is presented. During the first surgery, the facial nerve bifurcation obscured the promontory and round window. It was difficult to perform cochleostomy because of the lack of landmarks of the basal turn of the cochlea, and the first surgical attempt at cochleostomy was abandoned. A repeat CT scan was performed after the first surgery with reconstructed 3D images of the temporal bone and the cochlea, and then the cochlea was successfully opened at revision surgery. Reconstructed 3D CT images were very useful to identify the site of cochleostomy in this case with such difficult temporal bone anatomy.

AB - INTRODUCTION: Klippel-Trenaunay syndrome (KTS) is a rare congenital vascular disorder characterized by a triad of cutaneous port wine capillary malformations, varicose veins, and hemihypertrophy of bone and soft tissues. AIMS: To report on a rare case of KTS in an adult man manifested by painless urethral bleeding during penile erection briefly review the clinical presentation and management of the genitourinary forms of this syndrome. METHODS: On presentation, the clinical features of this patient, including medical history, signs and symptoms, and imaging examinations, were recorded. After diagnosis and initial treatment, a literature review of the urethral features of KTS was performed and is discussed in this report. RESULTS: A 35-year-old man with KTS presented with painless urethral bleeding during penile erection that was associated with posterior urethral vascular malformations. The coagulation method was used to treat the malformation, and no urethral bleeding or gross hematuria occurred during a postoperative follow-up period of 6 months. CONCLUSION: This case demonstrates that coagulation therapy and careful follow-up can be adequate treatment approaches for urethral features of KTS. However, the long-term efficacy of coagulation for this disorder should be investigated further. Lei H, Guan X, Han H, et al.

PMID- 29452832 TI - Delayed endovascular aortic repair is associated with reduced in-hospital mortality in patients with blunt thoracic aortic injury. AB - OBJECTIVE: The traditional approach to stable blunt thoracic aortic injury (BTAI) endorsed by the Society for Vascular Surgery is early (<24 hours) thoracic endovascular aortic repair (TEVAR). Recently, some studies have shown improved mortality in stable BTAI patients repaired in a delayed manner (>=24 hours). However, the indications for use of delayed TEVAR for BTAI are not well characterized, and its overall impact on the patient's survival remains poorly understood. We sought to determine whether delayed TEVAR is associated with a decrease in mortality compared with early TEVAR in this population. METHODS: We conducted a retrospective cohort study of adult patients with BTAI (International Classification of Diseases, Ninth Revision diagnosis code 901.0) who underwent TEVAR (International Classification of Diseases, Ninth Revision procedure code 39.73) from 2009 to 2013 using the National Sample Program data set. Missing physiologic data were imputed using chained multiple imputation. Patients were parsed into groups based on the timing of TEVAR (early, <24 hours, vs delayed, >=24 hours). The chi2, Mann-Whitney, and Fisher exact tests were used to compare baseline characteristics and outcomes of interest between groups. Multivariable logistic regression for mortality was performed that included all variables significant at P <= .2 in univariate analyses. RESULTS: A total of 2045 adult patients with BTAI were identified, of whom 534 (26%) underwent TEVAR. Patients with missing data on TEVAR timing were excluded (n = 27), leaving a total of 507 patients for analysis (75% male; 69% white; median age, 40 years [interquartile range, 27-56 years]; median Injury Severity Score [ISS], 34 [interquartile range, 26-41]). Of these, 378 patients underwent early TEVAR and 129 underwent delayed TEVAR. The two groups were similar with regard to age, sex, race, ISS, and presenting physiology. Mortality was 11.9% in the early TEVAR group vs 5.4% in the delayed group, with the early group displaying a higher odds of death (odds ratio, 2.36; 95% confidence interval, 1.03-5.36; P = .042). After adjustment for age, ISS, and admission physiology, the association between early TEVAR and mortality was preserved (adjusted odds ratio, 2.39; 95% confidence interval, 1.01 5.67; P = .047). CONCLUSIONS: Consistent with current Society for Vascular Surgery recommendations, more BTAI patients underwent early TEVAR than delayed TEVAR during the study period. However, delayed TEVAR was associated with significantly reduced mortality in this population. Together, these findings support a need for critical appraisal and clarification of existing practice guidelines in management of BTAI. Future studies should seek to understand this survival disparity and to determine optimal selection of patients for early vs delayed TEVAR. PMID- 29452833 TI - Endothelial vascular cell adhesion molecule 1 is a marker for high-risk carotid plaques and target for ultrasound molecular imaging. AB - BACKGROUND: Molecular imaging of carotid plaque vulnerability to atheroembolic events is likely to lead to improvements in selection of patients for carotid endarterectomy (CEA). The aims of this study were to assess the relative value of endothelial inflammatory markers for this application and to develop molecular ultrasound contrast agents for their imaging. METHODS: Human CEA specimens were obtained prospectively from asymptomatic (30) and symptomatic (30) patients. Plaques were assessed by semiquantitative immunohistochemistry for vascular cell adhesion molecule 1 (VCAM-1), lectin-like oxidized low-density lipoprotein receptor 1, P-selectin, and von Willebrand factor. Established small peptide ligands to each of these targets were then synthesized and covalently conjugated to the surface of lipid-shelled microbubble ultrasound contrast agents, which were then evaluated in a flow chamber for binding kinetics to activated human aortic endothelial cells under variable shear conditions. RESULTS: Expression of VCAM-1 on the endothelium of CEA specimens from symptomatic patients was 2.4-fold greater than that from asymptomatic patients (P < .01). Expression was not significantly different between groups for P-selectin (P = .43), von Willebrand factor (P = .59), or lectin-like oxidized low-density lipoprotein receptor 1 (P = .99). Although most plaques from asymptomatic patients displayed low VCAM-1 expression, approximately one in five expressed high VCAM-1 similar to plaques from symptomatic patients. In vitro flow chamber experiments demonstrated that VCAM-1-targeted microbubbles bind cells that express VCAM-1, even under high shear conditions that approximate those found in human carotid arteries, whereas binding efficiency was lower for the other agents. CONCLUSIONS: VCAM-1 displays significantly higher expression on high-risk (symptomatic) vs low-risk (asymptomatic) carotid plaques. Ultrasound contrast agents bearing ligands for VCAM-1 can sustain high-shear attachment and may be useful for identifying patients in whom more aggressive treatment is warranted. PMID- 29452834 TI - Pain and analgesic drugs in chronic venous ulcers with topical sevoflurane use. AB - OBJECTIVE: Pain in chronic venous ulcers (CVUs) notably increases with the usual cleaning of the wound. Chronic pain is usually poorly controlled even with the multiple analgesic treatments available. Analgesics can have different serious adverse effects and medical interactions in old patients with several comorbidities. This study reports the efficacy and safety of topical sevoflurane for treatment of pain in CVUs. METHODS: We report a descriptive and retrospective study of 30 patients older than 65 years with painful CVUs refractory to conventional analgesic treatments. Patients received topical sevoflurane treatment before the usual cleaning of the ulcer. Cleaning visits with sevoflurane every 2 days for a period of 1 month were scheduled. We compared the visual analog scale results and analgesic drugs for cleaning with and without topical sevoflurane. The systemic pharmacokinetics of sevoflurane after topical application has not been determined. RESULTS: Pain related to CVUs decreased with topical sevoflurane. Sevoflurane had an analgesic effect with latency time between 2 and 7 minutes. The duration of analgesia ranged between 8 and 18 hours. The time needed to take an analgesic treatment increased after application of sevoflurane. The use of other conventional analgesic drugs, including paracetamol, metamizole, nonsteroidal anti-inflammatory drugs, tramadol, and major opioids, was progressively reduced. The main local adverse effects were mild and transient, including heat, pruritus, and erythema. There were no systemic adverse effects. CONCLUSIONS: Topical sevoflurane has an intense, fast, and long-lasting local analgesic effect with an adequate safety profile. It also diminishes the taking of other conventional analgesic drugs. Topical sevoflurane is an efficient and safe therapeutic alternative for refractory painful CVUs. PMID- 29452835 TI - A comparison of preoperative and intraoperative vein mapping sizes for arteriovenous fistula creation. AB - BACKGROUND: Duplex ultrasound (DUS) mapping of the veins and arteries of the upper extremity is a well-established practice in arteriovenous fistula creation for long-term hemodialysis access. Previous publications have shown that vein diameters varying from 2 to 3 mm are predictive of success. Regional anesthesia is known to result in vasodilation and thus to increase the diameter of upper extremity veins. This study compares the sizes of veins measured by preoperative DUS mapping with those obtained after regional anesthesia to determine whether intraoperative DUS results in increased vein diameters and thus changes in the operative plan. A second goal was to determine whether such changes resulted in functional access. METHODS: This was a prospective observational study conducted between July 2013 and December 2014. Consecutive patients were preoperatively mapped and then intraoperatively mapped after administration of a regional anesthetic. Comparison of vein mapping sizes and comparison of preoperative plan and operative procedure based on the preoperative and intraoperative DUS mapping, respectively, were analyzed with a repeated-measures linear model. Significance testing was two sided, with a significance level of 5%. RESULTS: Sixty-five patients with end-stage renal disease underwent placement of arteriovenous access with preoperative and intraoperative DUS mapping after regional anesthesia. Comorbidities were representative of the vascular population. After regional anesthesia, intraoperative mid forearm and distal forearm cephalic veins were significantly larger than their respective preoperative measurements. Average increase in diameter of the mid forearm cephalic vein and distal forearm was 0.96 mm (P < .001) and 0.50 mm (P = .04), respectively. There was a significant difference in the number and configuration of arteriovenous accesses (P < .0001). There was more than a twofold significant increase in radial artery-based access procedures concomitant with a significant reduction of brachial-based access procedures and a reduction in graft access procedures. Overall functional access rate was 63%, and patency rates were comparable to those reported in the literature. CONCLUSIONS: The routine use of intraoperative DUS mapping after regional anesthesia is recommended to determine the optimal access site for chronic hemodialysis access. Identifying additional access options not seen with physical examination and preoperative DUS mapping will provide end-stage renal disease patients with more fistula options and hence a longer access life span for a lifelong disease.

PMID- 29452837 TI - Dramatically Polarized Opinion on the Role of Brachytherapy Boost in Management of High-risk Prostate Cancer: A Survey of North American Genitourinary Expert Radiation Oncologists. AB - INTRODUCTION: Three randomized clinical trials have established brachytherapy (BT) boost in combination with external beam radiation therapy (EBRT) and androgen deprivation therapy (ADT) as superior to definitive EBRT and ADT alone in terms of biochemical control (but not overall survival) at the expense of increased toxicity in men with high-risk (HR) prostate cancer (PCa). The current view regarding these 2 treatment algorithms among North American genitourinary (GU) experts is not known. METHODS: A survey was distributed to 88 practicing North American GU physicians serving on decision-making committees of cooperative group research organizations. Questions pertained to opinions regarding BT as monotherapy for low-risk PCa and BT boost for HR PCa. Responders were asked to self-identify as BT experts versus non-experts. Treatment recommendations were correlated with practice patterns using the Fisher exact test. RESULTS: Forty-two radiation oncologists completed the survey, of whom 23 (55%) recommend EBRT and ADT alone and 19 (45%) recommend addition of BT boost. Twenty-five participants (60%) identified themselves as BT experts. Nearly 90% of those recommending BT boost were BT experts versus approximately 10% of non-BT experts (P < .001). Responders who recommended BT monotherapy as first-choice treatment for low-risk PCa were more likely to recommend BT boost for HR PCa (P < .0001). CONCLUSIONS: There is a dramatic polarization in opinions regarding incorporation of BT boost into EBRT + ADT therapy for patients with HR PCa among North American GU radiation oncology experts, who serve on decision-making committees and influence the national treatment guidelines and future clinical trials. Those who identify themselves as BT experts are significantly more likely to recommend BT boost. These findings are likely to influence the national guidelines and implementation of BT boost in current and future North American PCa clinical studies.

Considering that in Mexico blood safety is one of the goals of the National Action Programs, it is essential to evaluate banks through an External Quality Control Program. OBJECTIVE: To analyze one of the evaluations that showed the greatest participation (2014-2/lot46) of banks in the Mexican Republic in the detection of transfusion-transmitted diseases. MATERIALS AND METHODS: A randomized panel of infectious markers of HIV, HCV, HBV, Treponema pallidum and Trypanosoma cruzi was manufactured under high quality standards. The evaluation criteria for each infectious marker were the identification of false positives and false negative results. Additionally, technologies used to detect infectious markers were requested for each bank. RESULTS: Of the 503 banks, only 374 participated in the evaluation. Technologies based on chemiluminescence, immunofluorescence and immunocolorimetry were used to detect viral markers. Even rapid tests for T. pallidum continue to be the methods of choice with 42%. Trypanosoma cruzi was 20% with fast techniques versus 80% with automated tests. Highest incidence of false positives was identified for T. pallidum and HBV, followed by T. cruzi, HIV and HCV. Fourteen (3.74%) false negatives results were identified for T. cruzi, followed by T. pallidum (n = 5/1.33%), HCV (n = 4/1.06) and HVB/HIV (n = 2/0.53%). CONCLUSION: False positive results identified for each infectious marker was considered high. This evidence will allow us to focus on areas of opportunity during serologic screening with greater emphasis on good laboratory practices.

AB - A series of 3(R)-aminopyrrolidine derivatives were designed and synthesized for JAK1-selective inhibitors through the modification of tofacitinib's core structure, (3R,4R)-3-amino-4-methylpiperidine. From the new core structures, we selected (R)-N-methyl-N-(pyrrolidin-3-yl)-7H-pyrrolo[2,3-d]pyrimidin-4-amine as a scaffold for further SAR studies. From biochemical enzyme assays and liver microsomal stability tests, (R)-3-(3-(methyl(7H-pyrrolo[2,3-d]pyrimidin-4 yl)amino)pyrrolidin-1-yl)-3-oxopropanenitrile (6) was chosen for further in vivo test through oral administration. Compound 6 showed improved selectivity for JAK1 compared to that of tofacitinib (IC50 11, 2.4 * 102, 2.8 * 103, and 1.1 * 102 nM for JAK1, JAK2, JAK3, and TYK2, respectively). In CIA and AIA model tests, compound 6 exhibited similar efficacy to tofacitinib citrate.

AB - Borrelidin A (1) is produced by several species of Streptomyces and within its bioactive scaffold, the vinylic nitrile moiety is essential for activity. We report herein newly discovered members of the borrelidin family, borrelidin F (2), borrelidin G (3), borrelidin H (4) and borrelidin I (5); all were isolated from Streptomyces rochei SCSIO ZJ89 originating from a mangrove-derived sediment sample. These structurally diverse metabolites enabled a number of new structure activity relationships (SARs) to be identified, especially with respect to the different configurations at the C11-OH and C12-C15 double bonds for which the absolute configurations were determined using spectroscopic methods. Importantly, borrelidin H (4) was found to have a therapeutic window superior to that of borrelidin A (1) in vitro and could inhibit migration of cancer cells.

AB - OBJECTIVES: We investigated the safety and efficacy of coronary orbital atherectomy to treat severely calcified lesions prior to stenting based upon age. BACKGROUND: The ORBIT II study reported the safety and efficacy with orbital atherectomy in 443 patients with severely calcified lesions. Elderly patients undergoing percutaneous coronary intervention may be at increased risk for major adverse cardiac events (MACE) and death compared with younger patients. METHODS: Patients were stratified according to age (>=75 year old [174/443, 39.3%] vs. <75 year old [269/443, 60.7%]). The MACE rate, defined as cardiac death, myocardial infarction (CK-MB > 3X ULN), and target vessel revascularization, was examined at 30-day and 3-year follow-up. RESULTS: Elderly and non-elderly groups had similar rates of procedural (87.9% vs. 89.5%, p = 0.64) and angiographic success (91.4% vs. 91.4%, p = 1.00). Severe angiographic complications were also similar in both groups (6.9% vs. 7.4%, p = 1.00). There was no statistically significant difference in MACE rates in the elderly and younger groups at 30 days (10.9% vs. 10.1%; p = 0.76) and 3 years (27.8% vs. 20.7%, p = 0.13). The individual endpoints of cardiac death (9.1% vs. 5.1%, p = 0.14), myocardial infarction (13.4% vs. 9.7%, p = 0.27), and target vessel revascularization (10.6% vs. 10.0%, p = 0.91) were also similar in both groups at 3 years. CONCLUSIONS: The rates of adverse clinical events in elderly patients who underwent orbital atherectomy were low and similar to the non-elderly patients, suggesting that it could be a reasonable treatment strategy for elderly patients with severely calcified lesions.

AB - BACKGROUND: Bleeding complications are associated with unfavorable outcomes in patients with acute coronary syndrome (ACS). Compared to Whites, several studies demonstrated a higher risk of bleeding in Asians who present with acute myocardial infarction. To date, the efficacy and safety of ticagrelor in East Asian population have not been well established. METHODS: We conducted a systematic review and meta-analysis of randomized controlled trials that compared ticagrelor and clopidogrel in East Asian patients with acute coronary syndrome (ACS). We systematically searched MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, and ClinicalTrial.gov database. RESULTS: Three randomized controlled trials, including a total of 1552 patients, met our inclusion criteria. Study countries included Japan, South Korea, and China. All studies defined primary efficacy endpoint and major bleeding events in accordance with the PLATO definition. Ticagrelor was associated with a numerically lower, albeit statistically nonsignificant, risk of primary efficacy endpoint defined as a composite of death from vascular causes, myocardial infarction, or stroke (odds ratio 0.84; 95% confidence interval 0.43-1.63; p = 0.60). Ticagrelor was associated with a significantly higher risk of PLATO-defined major bleeding compared to clopidogrel (odds ratio 1.52; 95% confidence interval 1.04-2.23; p = 0.03). CONCLUSIONS: Our meta-analysis demonstrated that ticagrelor was associated with a higher risk of major bleeding compared to clopidogrel in East Asian patients with ACS. Further studies evaluating the role of ticagrelor in management of ACS in East Asian patients are warranted. PMID- 29452844 TI - Fungal effectors at the crossroads of phytohormone signaling. AB - Phytohormone networks are crucial for maintaining the delicate balance between growth and biotic stress responses in plants. Jasmonic acid, salicylic acid, ethylene, and the associated signaling crosstalk are important for pathogen defense; whereas gibberellin and cytokinin function in growth and development in plants. Plant pathogenic fungi have evolved remarkable strategies to manipulate and/or hijack such phytohormone signaling cascades for their own benefit, thus leading to susceptibility and disease in host plants. Interestingly, these hormones are also targeted by fungal endosymbionts and mutualists during beneficial interactions with plants. We highlight current advances in our understanding of the role of fungal effectors in such antagonistic manipulation of phytohormones during pathogenic as well as symbiotic association with plant hosts. In addition to the aforementioned effector-based control, certain phytohormone mimics have recently emerged as a powerful molecular language in fungal manipulation of defense responses and innate immunity in plants. PMID- 29452845 TI - Just the surface: advances in the discovery and characterization of necrotrophic wheat effectors. AB - For many years pathogens of wheat have remained poorly understood. Hindered by an inaccessible host and the obligate nature of many of the pathogens, our understanding of these interactions has been limited compared to other more amenable pathosystems. However, breakthroughs over recent years have shed new light on diseases of wheat, particularly those caused by the genetically tractable necrotrophic pathogens. We now understand that many of the necrotrophic fungal pathogens do interact with wheat in a strict gene-for-gene relationship, and that pathogen and host partners in these interactions have now been identified. This improved understanding of necrotrophic effector biology has fundamentally changed the way we consider these important wheat diseases. PMID- 29452846 TI - Differential role of gpaB and sidA gene expressions in relation to virulence in Aspergillus species from patients with invasive aspergillosis. AB - The virulence genes in invasive aspergillosis (IA) have not been analyzed adequately. The present study was designed to evaluate the expression of gpaB and sidA genes, which are important virulence genes in Aspergillus spp. from bronchoalveolar lavage (BAL) samples. Direct examination and culture on Czapek Agar and Sabouraud Dextrose Agar media were performed for 600 BAL specimens isolated from patients with possible aspergillosis. A Galactomannan ELISA assay was also carried out. The expression levels of the gpaB and sidA genes in isolates were analyzed using quantitative real-time PCR (qRT-PCR). We identified 2 species, including Aspergillus flavus (A. flavus) and Aspergillus fumigatus (A. fumigatus) in 25 positive samples for invasive aspergillosis as validated using GM-ELISA. A. flavus is the main pathogen threatening transplant recipients and cancer patients worldwide. In this study, A. flavus had low levels of the gpaB gene expression compared to A. fumigatus (p=0.006). The highest sidA expression was detected in transplant recipients (p=0.05). There was no significant correlation between sidA expression and underlying disease (p=0.15). The sidA and gpaB gene expression patterns may provide evidence that these virulence genes play important roles in the pathogenicity of Aspergillus isolates; however, there are several regulatory genes responsible for the unexpressed sidA and gpaB genes in the isolates. PMID- 29452847 TI - Primary antibiotic resistance and its relationship with cagA and vacA genes in Helicobacter pylori isolates from Algerian patients. AB - The epidemiology of Helicobacter pylori resistance to antibiotics is poorly documented in Africa and especially in Algeria. The aim of our study was to determine the antibiotic resistance rates, as well as its possible relationship with VacA and CagA virulence markers of isolates from Algerian patients. One hundred and fifty one H. pylori isolate were obtained between 2012 and 2015 from 200 patients with upper abdominal pain. Antimicrobial susceptibility testing was performed for amoxicillin, clarithromycin, metronidazole, ciprofloxacin, rifampicin and tetracycline. Molecular identification of H. pylori and the detection of vacA and cagA genes were performed using specific primers. We found that H. pylori was present in 83.5% of collected biopsies, 54.9% of the samples were cagA positive, 49.67% were vacA s1m1, 18.30% were vacA s1m2 and 25.49% were vacA s2m2. Isolates were characterized by no resistance to amoxicillin (0%), tetracycline (0%), rifampicin (0%), a high rate of resistance to metronidazole (61.1%) and a lower rate of resistance to clarithromycin (22.8%) and ciprofloxacin (16.8%). No statically significant relationship was found between vagA and cagA genotypes and antibiotic resistance results (p>0.5) except for the metronidazole, which had relation with the presence of cagA genotype (p=0.001). PMID- 29452848 TI - Optimization of liquid fermentation conditions for biotransformation zein by Cordyceps militaris 202 and characterization of physicochemical and functional properties of fermentative hydrolysates. AB - Cordyceps militaris 202 is a potential fungus for biotransformation zein, due to its various proteases, high tolerance and viability in nature. In this article, single factor experiment and response surface methodology were applied to optimize the liquid fermentation conditions and improve the ability of biotransformation zein. The optimized fermentation conditions were as follows: inoculum concentration of 19%, volume of liquor of 130mL/500mL and pH of 4.7. Under this condition, the degree of hydrolysis (DH) was 27.31%. The zein hydrolysates from fungi fermentation maintained a high thermal stability. Compared to the original zein, the zein hydrolysates were found to have high solubility, which most likely results in improved foaming and emulsifying properties. Overall, this research demonstrates that hydrolysis of zein by C. militaris 202 is a potential method for improving the functional properties of zein, and the zein hydrolysates can be used as functional ingredients with an increased antioxidant effect in both food and non-food applications. PMID- 29452849 TI - Bacterial communities in mining soils and surrounding areas under regeneration process in a former ore mine. AB - Human activities on the Earth's surface change the landscape of natural ecosystems. Mining practices are one of the most severe human activities, drastically altering the chemical, physical and biological properties of the soil environment. Bacterial communities in soil play an important role in the maintenance of ecological relationships. This work shows bacterial diversity, metabolic repertoire and physiological behavior in five ecosystems samples with different levels of impact. These ecosystems belong to a historical area in Iron Quadrangle, Minas Gerais, Brazil, which suffered mining activities until its total depletion without recovery since today. The results revealed Proteobacteria as the most predominant phylum followed by Acidobacteria, Verrucomicrobia, Planctomycetes, and Bacteroidetes. Soils that have not undergone anthropological actions exhibit an increase ability to degrade carbon sources. The richest soil with the high diversity was found in ecosystems that have suffered anthropogenic action. Our study shows profile of diversity inferring metabolic profile, which may elucidate the mechanisms underlying changes in community structure in situ mining sites in Brazil. Our data comes from contributing to know the bacterial diversity, relationship between these bacteria and can explore strategies for natural bioremediation in mining areas or adjacent areas under regeneration process in iron mining areas. PMID- 29452850 TI - Evaluation of dot-blot test for serological diagnosis of bovine brucellosis. AB - The objective of this study was to standardize and validate the dot-blot test for the serological diagnosis of bovine brucellosis, compare the results with those found in the 2-mercaptoethanol (2-ME) and complement fixation test (CF), and estimate the relative sensitivity and specificity of the dot-blot compared to these tests. Fifty bovine blood serum samples were used for the test standardization, and 1315 samples were used for evaluation and comparison between the tests; the results were compared using the Kappa indicator. At the end of standardization, it was established as optimal for the antigen obtained from Brucella abortus B19 after passing through a microorganism rupture process, the blood serum samples diluted at 1:100, and the conjugate at 1:30,000. The comparison of the dot-blot results with 2-ME showed Kappa index of 0.9939, sensitivity of 99.48%, and specificity 99.91%, with CF, Kappa index of 0.8226, sensitivity 100% and specificity 95.32%. Using the combination of the test results 2-ME and CF to establish the true condition of the animal, the dot-blot showed relative sensitivity of 100%, and relative specificity of 99.91%. The evaluated test proved to be effective and reliable, besides being easy to handle and interpret the results. PMID- 29452851 TI - Elastin increases biofilm and extracellular matrix production of Aspergillus fumigatus. AB - Aspergillus fumigatus is an opportunistic saprobe fungus that accounts for 90% of cases of pulmonary aspergillosis in immunosuppressed patients and is known for its angiotropism. When it reaches the respiratory tract, A. fumigatus interacts with structural components and blood vessels of the lungs, such as elastin. To understand the effect of this structural component, we examined the effect of elastin on the production and development of the biofilm of A. fumigatus. In RPMI containing 10mg/mL of elastin, a significant increase (absorbance p<0.0001; dry weight p<0.0001) in the production of biofilm was observed in comparison to when RPMI was used alone, reaching a maximum growth of 18.8mg (dry weight) of biofilm in 72h. In addition, elastin stimulates the production (p=0.0042) of extracellular matrix (ECM) and decreases (p=0.005) the hydrophobicity during the development of the biofilm. These results suggest that elastin plays an important role in the growth of A. fumigatus and that it participates in the formation of thick biofilm. PMID- 29452852 TI - Reduction of patient radiation dose with a new organ based dose modulation technique for thoraco-abdominopelvic computed tomography (CT) (Liver dose right index). AB - PURPOSE: To evaluate the radiation dose reduction, image quality and diagnostic confidence with thoraco-abdominopelvic computed tomography (TACT) using a new organ based dose modulation system (liver dose right index [Liver DRI]), compared to TACT using a standard automatic exposure control adjusting mA according to attenuation. METHODS: A total of 37 patients who had two TACT examinations on 2 different CT scanners, one using standard automatic exposure control (combination of a DoseRight automatic current selection and Z modulation) and one using Liver DRI were included. There were 19 men and 18 women with a mean age of 67.6+/-11.7 (SD) years (range: 36-85 years) For each patient, volume CT dose index (CTDIvol), size-specific dose estimates (SSDE) and signal-to-noise ratio (SNR) were evaluated at each anatomic level (lung, breast, liver and pelvis area) for each protocol. Two radiologists assessed independently image quality, artifacts and diagnostic confidence. RESULTS: The radiation dose decreased significantly using Liver DRI compared to standard automatic exposure control on the total scan length, lung, breast and pelvis area, with a significant CTDIvol reduction of 27% (P=0.0001), 23% (P=0.0002), 24% (P=0.0002) and 31% (P=0.0001), respectively; and a significant SSDE reduction of 23% (P=0.0001), 28% (P=0.0001), 23% (P=0.0002) and 29% (P=0.0001), respectively. No significant SNR reductions were observed in all measured tissues at the level of the aortic arch, celiac trunk and iliac bifurcation, except in the muscle (P=0.0013) and fat tissue (P=0.0052) at the level of the ureteral meatus. No significant differences were noted between both protocols in overall image quality, artifacts and diagnostic confidence with an excellent inter observer agreement between radiologists (Kappa values of 0.83, 0.85 and 0.88, respectively). CONCLUSION: Liver DRI organ based dose modulation technique allows significant dose reduction compared to standard automatic exposure control while preserving diagnostic image quality in all thoraco abdominopelvic areas. PMID- 29452853 TI - The impact of sex steroid agonists and antagonists on folliculogenesis in the neonatal porcine ovary via cell proliferation and apoptosis. AB - The objective of the study was to examine the effects of androgen and estrogen agonists or antagonists on the follicle formation, ovarian cell proliferation and apoptosis as well as plasma steroid concentration in neonatal pigs. Piglets were injected with testosterone propionate (TP, 20 mg/kg bw), flutamide (FLU, 50 mg/kg bw), 4-tert-octylphenol (OP, 100 mg/kg bw), ICI 182,780 (ICI, 400 MUg/kg bw), methoxychlor (MXC, 100 mg/kg bw) or corn oil (CTR, controls) between postnatal Days 1 and 10 (n = 4/group). Heart blood was collected and ovaries were excised from the 11-day-old piglets. The lower percentage of oocytes within an egg nest and higher ovarian expression of active caspase 3 were found in TP (androgen excess) piglets compared to controls. FLU-induced androgen deficiency decreased the percentage of primordial follicles, increased that of early primary follicles and diminished ovarian cell proliferation. OP-induced estrogen action increased the percentage of primordial and developing follicles as well as cell proliferation. ICI-induced estrogen deficiency decreased the percentage of transitional follicles and ovarian cell proliferation, while increased the percentage of primordial follicles and the abundance of active caspase 3. Treatment with MXC, exhibiting estrogenic, antiestrogenic, and antiandrogenic activities, declined the percentage of developing follicles and cell proliferation. Moreover, the investigated compounds differentially affected plasma steroid level. In conclusion, the present study demonstrated clear effects of TP and FLU during the earliest stages of folliculogenesis in pigs (nest breakdown and follicle assembly), whereas OP and ICI influenced also the subsequent stages of follicle initial recruitment and growth. Therefore, the androgen and estrogen seems to be important for the follicle assembly and follicle growth in neonatal porcine ovaries. PMID- 29452854 TI - Assessment of the temperature cut-off point by a commercial intravaginal device to predict parturition in Piedmontese beef cows. AB - Dystocic parturitions have an adverse impact on animal productivity and therefore the profitability of the farm. In this regard, accurate prediction of calving is essential since it allows for efficient and prompt assistance of the dam and the calf. Numerous approaches to predict parturition have been studied, among these, measurement of intravaginal temperature (IVT) is the most effective method at the field level. Thus, objectives of this experiment were, 1) to find an IVT cut-off to predict calving within 24 h, and 2) to clarify the use of IVT as an automated method of calving detection in housed beef cows. A commercial intravaginal electronic device (Medria Vel'Phone(r)) with a sensor that measures the IVT every 12 h was used. Piedmontese cows (n = 211; 27 primiparous and 184 multiparous) were included in this study. One-way analysis of variance was used to assess the temperature differences at 0, 12, 24, 36, 48 and 60 h before parturition. Receiving operator characteristic curves were built to determine the temperature cut-off which predicts calving within 24 h with the highest summation of sensitivity (Se) and specificity (Sp). Binomial logistic regression models were computed to identify factors that may affect the IVT before calving. Mean gestation length was 291.5 +/- 13.7 d (primiparous, 292 +/- 14.1 d; multiparous, 289 +/- 9.2 d). A decrease (P < 0.001) in the average IVT was found from 60 h before calving until the expulsion of the IVT device. A significant (P < 0.05) reduction in the IVT was noticeable from 24 h before until parturition. The IVT drop to predict parturition 24 h before calving was 0.21 degrees C (area under the curve [AUC] = 0.72; Se = 66%, Sp = 76%). Furthermore, the IVT cut-off value to predict parturition within 24 h was 38.2 degrees C (AUC = 0.89; Se = 86%, Sp = 91%). None of the evaluated fixed effects (parity, dystocia, season or length of gestation) affected (P ? 0.05) the IVT variation from 60 h before and up to calving. To conclude, the IVT average seems to be a better parameter than the drop in temperature to predict parturition within 24 h. In this regard, a cut-off of 38.2 degrees C showed a high Se and Sp for predicting calving. This study demonstrates the usefulness of a commercially available device to predict calving to improve management in stabled beef farms. PMID- 29452855 TI - Constituents of neutrophil extracellular traps induce in vitro collagen formation in mare endometrium. AB - Neutrophil extracellular traps (NETs) are DNA complexes carrying nuclear and cytoplasmic proteins, such as elastase (ELA), cathepsin-G (CAT) and myeloperoxidase (MPO). Mare endometrosis is a chronic degenerative process characterized by excessive collagen in endometrium. While NETs fight bacteria that cause endometritis, they may trigger endometrial fibrogenesis. The aim was to evaluate the in vitro effect of some NETs components on mare endometrial fibrogenesis and determine its relationship with histopathology or estrous cycle. Endometrial explants were incubated with NETs components (ELA, CAT, MPO or oxytocin). Collagen type I (COL1) protein and type I and III (COL3) gene transcription were evaluated in follicular and mid-luteal phases endometria (Kenney and Doig type I/IIA and IIB/III). Increased COL1 occurred with all NETs proteins, although endometrial response to each NETs protease depended on estrous cycle and/or endometrial category. Since ELA enhanced COL1 production, NETs persistence might be linked to endometrosis. Estrous cycle influenced COL1 protein concentration and COL3 transcripts, suggesting that follicular phase may favor endometrial collagen production. However, luteal phase endometria with moderate or severe lesions may be also susceptible to fibrotic effects of NETs constituents. These data propose that NETs involvement in chronic endometritis in mares may act as putative endometrial fibrogenic mediators. PMID- 29452856 TI - Generalized cardiovascular disease on a preoperative CT scan is predictive for anastomotic leakage after esophagectomy. AB - BACKGROUND: Recent studies demonstrated that calcification of arteries supplying the gastric tube is associated with anastomotic leakage after esophagectomy. However, it remains unclear whether this association only derives from local flow limitations, or generalized vascular disease as well. The purpose of this study was to determine whether calcification throughout the entire cardiovascular system is associated with anastomotic leakage. METHODS: Consecutive patients who underwent an esophagectomy with gastric tube reconstruction and cervical anastomosis for esophageal cancer were analyzed. Diagnostic CT images were scored for the presence of arterial calcification on 10 locations based on a visual grading system. The association with anastomotic leakage was studied using logistic regression analysis. RESULTS: A total of 406 patients were included for analysis of whom 104 developed anastomotic leakage (25.6%). Presence of calcification in the coronary arteries (minor calcification: 36.5% leakage; no calcification: 18.1%, p = .001), supra-aortic arteries (minor calcification: 30.9% leakage; major calcification: 35.3%; no calcification: 16.1%, p = .007 and p < .001, respectively) and thoracic aorta (major calcification: 33.3% leakage; no calcification: 19.4%, p = .011) was associated with leakage. In multivariable analysis, minor calcification of the coronary arteries (OR 2.29, 95% CI: 1.28 4.12, p = .005) and calcification of the supra-aortic arteries (OR 2.48, 95% CI: 1.30-4.74, p = .006 for minor calcification and OR 2.72, 95% CI: 1.49-4.99, p = .001 for major calcification) remained independently associated with leakage. CONCLUSIONS: Calcification of the coronary and supra-aortic arteries on routine CT are predictive of cervical anastomotic leakage after esophagectomy. These results suggest that generalized cardiovascular disease is a strong indicator for the risk of leakage. PMID- 29452857 TI - Impact of the off-clamp endoscopic robot-assisted simple enucleation (ERASE) of clinical T1 renal tumors on the postoperative renal function: Results from a matched-pair comparison. AB - PURPOSE: To evaluate the surgical and functional outcomes of a matched-paired series of on-clamp vs off-clamp endoscopic robot-assisted simple enucleation (ERASE) and standardized renorraphy in a tertiary referral institution, to search for predictors of functional drop after surgery and to investigate the influence of off-clamp technique in patients presenting these characteristics. MATERIALS AND METHODS: A matched-pair comparison of 120 on-clamp vs 120 off-clamp over 491 patients treated with ERASE was performed. Perioperative and functional outcomes were compared between groups. RESULTS: Patients treated with on-clamp and off clamp technique had comparable complication and positive surgical margin rate. The off-clamp group had a significantly lower eGFR drop compared to the on-clamp group at 3rd postoperative day (POD) (1% vs 7%, p = 0.0001) and at 30th POD (2.5% vs 9%, p = 0.01) from baseline. This difference lost its statistical significance at 6th month and at last follow-up (median 40 months). At multivariable analysis the Charlson comorbidity index (OR 2.06, p < 0.0001), uncontrolled type 2 diabetes mellitus (OR 4.13, p < 0.001) were independent predictive factors of a >15% eGFR drop from baseline to last follow-up. In a subanalysis over 64 comorbid patients, those patients who underwent off-clamp ERASE had a significantly lower eGFR drop compared to the comorbid counterpart during the whole follow-up. CONCLUSIONS: The off-clamp ERASE is a safe surgical technique with a significantly lower renal function drop compared to on-clamp ERASE in the early perioperative time. Patients with comorbidity might represent a subgroup of patients having a functional benefit after off-clamp RAPN even in the long-term period. PMID- 29452858 TI - The effect of being informed on receiving immediate breast reconstruction in breast cancer patients. AB - INTRODUCTION: In previous research from the NABON breast cancer audit, observed hospital variation in immediate breast reconstruction (IBR) rates in the Netherlands could not be fully explained by tumour, patient, and hospital factors. The process of information provision and decision-making may also contribute to the observed variation; the objective of the current study was to give insight in the underlying decision-making process for IBR and to determine the effect of being informed about IBR on receiving IBR. METHODS: A total of 502 patients with IBR and 716 without IBR treated at twenty-nine hospitals were invited to complete an online questionnaire on obtained information and decision making regarding IBR. The effect of being informed about IBR on receiving IBR was determined by logistic regression analysis. RESULTS: Responses from five hundred and ten patients (n = 229 IBR, n = 281 without IBR) were analysed. Patients with IBR compared to patients without reconstruction showed a difference in patient, tumour, treatment (including radiotherapy), and hospital characteristics. Patients with IBR were more often informed about IBR as a treatment option (99% vs 73%), they discussed (dis)advantages more often with their physician (86% vs 68%), and they were more often involved in shared decision-making (91% vs 67%) compared to patients without IBR. Multivariate logistic regression analysis, corrected for confounders, showed that being informed about IBR increased the odds for receiving IBR fourteen times (p < 0.001). CONCLUSIONS: The positive effect of being informed about IBR on receiving IBR stresses the importance of treatment information in the decision-making process for IBR. PMID- 29452859 TI - Evaluation of liquid biopsies for detection of emerging mutated genes in metastatic colorectal cancer. AB - BACKGROUND: Detection of gene mutations is important for planning molecular targeted therapy. Although most gene mutations are concordant between primary colon cancers and their liver metastases, new mutations can emerge in metastases. The liquid biopsy is a newly developed, gene analytic method to detect mutations in metastatic tumors. In this prospective study, we evaluated the applicability of liquid biopsies in the detection of mutations in primary and metastatic tumors. METHODS: We included 22 patients with liver metastases from colorectal cancer and extracted DNA from primary colorectal tumors, metastatic liver tumors, and peripheral blood (liquid biopsy). Next-generation sequencing (NGS) and digital PCR were performed to detect mutations in these three sample types. RESULTS: We found a total of 36 different mutations in samples from primary tumors, liver metastases, and liquid biopsies using NGS. Twenty-eight of these mutations were found in all three types of samples, whereas liquid biopsy did not identify four mutations that had been found in both primary tumors and liver metastases, but did identify four mutations that were found in liver tumors but not in primary tumors. The sensitivity of liquid biopsies for detecting mutations in liver metastases was 64% (23/36) using NGS and 89% (32/36, P = 0.02) using dPCR. The specificities of NGS and dPCR were 100% (23/23) and 100% (32/32), respectively. CONCLUSIONS: Emerging mutations, which are not found in primary tumors, can be detected in their metastases and liquid biopsies.

AB - BACKGROUND: In retroperitoneal sarcoma (RPS), the optimal extent of resection must balance adequate disease control with potential for morbidity. We sought to study the frequency and outcomes after a Whipple procedure or pancreaticoduodenectomy (PD) in patients undergoing resection for primary RPS. METHODS: Participating referral centers within the Trans-Atlantic Retroperitoneal Sarcoma Working Group provided retrospective data from January 2007 to December 2016 for patients with primary RPS who underwent PD along with the total number of consecutive resections done during the same time period. Data from participating centers were combined for analysis. RESULTS: In total, 29 patients underwent PD among 2068 resections performed for primary RPS (1.4%). The predominant histologic subtypes were liposarcoma and leiomyosarcoma. All PD patients underwent concomitant resection of additional organs (median: 2, range: 1-5), including 13 patients (45%) who also received vena cava resection. Definitive evidence of microscopic invasion of the duodenum or pancreas was seen in 84% of patients. Postoperatively, 10 patients (34%) had major complications including 8 (28%) that developed a clinically-significant pancreatic leak. One postoperative death (3.4%) occurred. With a median follow-up of 4.8 years, 19 patients (66%) developed disease recurrence. The patterns of recurrence were dependent on histologic subtype. CONCLUSION: Although infrequent, when PD is done for primary RPS, resection of additional organs is often required and major complication rates are moderate. The recurrence rate is overall high and the pattern of recurrence is dictated by histologic subtype. PMID- 29452863 TI - Chest wall toxicity after hypofractionated proton beam therapy for liver malignancies. AB - PURPOSE: Normal liver-sparing with proton beam therapy (PBT) allows for dose escalation in the treatment of liver malignancies, but it may result in high doses to the chest wall (CW). CW toxicity (CWT) data after PBT for liver malignancies are limited, with most published reports describing toxicity after a combination of hypofractionated proton and photon radiation therapy. We examined the incidence and associated factors for CWT after hypofractionated PBT for liver malignancies. METHODS AND MATERIALS: We retrospectively reviewed the charts of 37 consecutive patients with liver malignancies (30 hepatocellular carcinoma, 6 intrahepatic cholangiocarcinoma, and 1 metastasis) treated with hypofractionated PBT. CWT was scored using Common Terminology Criteria for Adverse Events, version 4. Receiver-operating characteristic curves were used to identify patient and dosimetric factors associated with CWT and to determine optimal dose-volume histogram parameters/cutoffs. Cox regression univariate analysis was used to associate factors to time-dependent onset of CWT. RESULTS: Thirty-nine liver lesions were treated with a median dose of 60 GyE (range, 35-67.5) in 15 fractions (range, 13-20). Median follow-up was 11 months (range, 2-44). Grade >=2 and 3 CW pain occurred in 7 (19%) and 4 (11%) patients, respectively. Median time to onset of pain was 6 months (range, 1-14). No patients had radiographic rib fracture. On univariate analysis, CW equivalent 2 Gy dose with an alpha/beta = 3 Gy (EQD2alpha/beta=3), V57 >20 cm3 (hazard ratio [HR], 2.7; P = .004), V63 >17 cm3 (HR, 2.7; P = .003), and V78 >8 cm3 (HR, 2.6; P = .003) had the strongest association with grade >=2 CW pain, as did tumor dose of >75 Gy EQD2alpha/beta=10 (HR, 8.7; P = .03). No other patient factors were associated with CWT. CONCLUSIONS: CWT after hypofractionated PBT for liver malignancies is clinically relevant. For a 15-fraction regimen, V47 >20 cm3, V50 >17 cm3, and V58 >8 cm3 were associated with higher rates of CWT. Further investigation of PBT techniques to reduce CW dose are warranted. PMID- 29452862 TI - Protective Effect of Human Leukocyte Antigen (HLA) Allele DRB1*13:02 on Age Related Brain Gray Matter Volume Reduction in Healthy Women. AB - BACKGROUND: Reduction of brain volume (brain atrophy) during healthy brain aging is well documented and dependent on genetic, lifestyle and environmental factors. Here we investigated the possible dependence of brain gray matter volume reduction in the absence of the Human Leukocyte Antigen (HLA) allele DRB1*13:02 which prevents brain atrophy in Gulf War Illness (James et al., 2017). METHODS: Seventy-one cognitively healthy women (32-69years old) underwent a structural Magnetic Resonance Imaging (sMRI) scan to measure the volumes of total gray matter, cerebrocortical gray matter, and subcortical gray matter. Participants were assigned to two groups, depending on whether they lacked the DRB1*13:02 allele (No DRB1*13:02 group, N=60) or carried the DRB1*13:02 allele (N=11). We assessed the change of brain gray matter volume with age in each group by performing a linear regression where the brain volume (adjusted for total intracranial volume) was the dependent variable and age was the independent variable. FINDINGS: In the No DRB1*13:02 group, the volumes of total gray matter, cerebrocortical gray matter, and subcortical gray matter were reduced highly significantly. In contrast, none of these volumes showed a statistically significant reduction with age in the DRB1*13:02 group. INTERPRETATION: These findings document the protective effect of DRB1*13:02 on age-dependent reduction of brain gray matter in healthy individuals. Since the role of this allele is to connect to matching epitopes of external antigens for the subsequent production of antibodies and elimination of the offending antigen, we hypothesize that its protective effect may be due to the successful elimination of such antigens to which we are exposed during the lifespan, antigens that otherwise would persist causing gradual brain atrophy. In addition, we consider a possible beneficial role of DRB1*13:02 attributed to its binding to cathepsin S, a known harmful substance in brain aging (Wendt et al., 2008). Of course, other factors covarying with the presence of DRB1*13:02 could be involved. PMID- 29452865 TI - Stereotactic radiosurgery for multiple brain metastases: Results of multicenter benchmark planning studies. AB - PURPOSE: Stereotactic radiosurgery is indicated for treatment of multiple brain metastases. Various treatment platforms are available, but most comparisons are limited to single-center studies. As part of a national commissioning program, benchmark planning cases were completed by 21 clinical centers, providing a unique dataset of current practice across a large number of providers and equipment platforms. METHODS AND MATERIALS: Two brain metastases cases were provided, with images and structures predrawn, involving 3 and 7 lesions. Centers produced plans according to their local practice, which were reviewed centrally using metrics for target coverage, selectivity, gradient fall-off, and normal tissue sparing. RESULTS: Fifty plans were submitted, using 24 treatment platforms. Eleven plans were revised following feedback, including 2 centers that acquired a new platform; 1 other center accepted a restriction of service. All centers prioritized coverage, with the prescription isodose covering >=95% of 233 of 235 target volumes. Selectivity was much more variable, especially for smaller lesions, and when combined with poor gradient indices resulted in large volumes of normal tissue being irradiated. Tomotherapy submissions were outliers for either selectivity or gradient index, but other platforms could produce plans with relatively low gradient indices for larger lesion volumes. There was more variation among Varian and Elekta LINAC plans than for Gamma Knife and CyberKnife, and larger differences for smaller targets, both inter- and intratreatment platform. Doses to normal brain and brainstem were highest when margins were applied, but improvements were possible by replanning alone. CONCLUSIONS: Multicenter benchmarking exercises have highlighted some variation in clinical practice and priorities, with a few outliers. Most platforms are able to achieve comparable plans, except for the smallest volumes and when larger planning margins are used. The data will be used to advance standardization and quality improvement of national services and can provide useful guidance for centers worldwide.

PMID- 29452866 TI - Intrapatient study comparing 3D printed bolus versus standard vinyl gel sheet bolus for postmastectomy chest wall radiation therapy. AB - PURPOSE: This patient study evaluated the use of 3-dimensional (3D) printed bolus for chest wall radiation therapy compared with standard sheet bolus with regard to accuracy of fit, surface dose measured in vivo, and efficiency of patient setup. By alternating bolus type over the course of therapy, each patient served as her own control. METHODS AND MATERIALS: For 16 patients undergoing chest wall radiation therapy, a custom 5.0 mm thick bolus was designed based on the treatment planning computed tomography scan and 3D printed using polylactic acid. Cone beam computed tomography scanning was used to image and quantify the accuracy of fit of the 2 bolus types with regard to air gaps between the bolus and skin. As a quality assurance measure for the 3D printed bolus, optically stimulated luminescent dosimetry provided in vivo comparison of surface dose at 7 points on the chest wall. Durations of patient setup and image guidance were recorded and compared. RESULTS: In 13 of 16 patients, the bolus was printed without user intervention, and the median print time was 12.6 hours. The accuracy of fit of the bolus to the chest wall was improved significantly relative to standard sheet bolus, with the frequency of air gaps 5 mm or greater reduced from 30% to 13% (P < .001) and maximum air gap dimension diminished from 0.5 +/- 0.3 to 0.3 +/- 0.3 mm on average. Surface dose was within 3% for both standard sheet and 3D printed bolus. On average, the use of 3D printed bolus reduced the setup time from 104 to 76 seconds. CONCLUSIONS: This study demonstrates 3D printed bolus in postmastectomy radiation therapy improves fit of the bolus and reduces patient setup time marginally compared with standard vinyl gel sheet bolus. The time savings on patient setup must be weighed against the considerable time needed for the 3D printing process. PMID- 29452867 TI - Deep inspiration breath hold level variability and deformation in locoregional breast irradiation. AB - PURPOSE: The purpose of this study was to evaluate the dosimetric effect of breath hold level variability and deformation on breast, chest wall, internal mammary chain (IMC) nodes, and heart. METHODS AND MATERIALS: Left-sided post lumpectomy (n = 12) and postmastectomy (n = 3) patients underwent deep inspiration breath hold (DIBH) and exhale breath hold (EBH) computed tomography (CT) scans. Forward-planned locoregional breast plans were created on the DIBH scan. Two effects were modeled assuming no setup uncertainties: residual motion within the gating window and systematically shallow breath hold levels (BHLs). Real-time position management (RPM) was used to monitor BHL at simulation and during treatment. The RPM data were scaled to simulate BHL variation within symmetric gating window widths of +/-1, 3, 5, and 7 mm; the dosimetric impact of this motion was simulated in the treatment planning system. Systematically "shallow" BHL errors were modeled using deformable image registration to map the patient trajectory from DIBH to EBH (n = 12). The deformable vector fields were scaled to produce synthetic CT scans modeling patient position during breath holds 1, 3, 5, and 7 mm shallower than simulator BHL. The original treatment plans were applied to the synthetic CTs and dose was recalculated. RESULTS: Acceptable plan quality was maintained for most patients with motion within gating windows up to +/-7 mm. Patients with shallow median BHLs experienced loss of coverage at simulated gating windows +/-5 mm or larger. At systematic 3 mm shallow BHL error, 4/12 patients had clinical target volume IMC V80% < 99%; this increased to 11/12 patients at 5 mm. Change in heart dose from systematic BHL errors was negligible. CONCLUSIONS: Motion within gating windows has minimal dosimetric impact for most BHL variability; however, loss of IMC coverage can occur even for small gating windows when BHLs are systematically shallow. This can be mitigated by restricting lower BHL tolerances or accounting for known uncertainties in planning. PMID- 29452868 TI - Chest wall dose reduction using noncoplanar volumetric modulated arc radiation therapy for lung stereotactic ablative radiation therapy. AB - PURPOSE: Stereotactic ablative radiation therapy (SABR) to lung tumors close to the chest wall can cause rib fractures or chest wall pain. We evaluated and propose a clinically practical solution of using noncoplanar volumetric modulated arc radiation therapy (VMAT) to reduce chest wall dose from lung SABR. METHODS AND MATERIALS: Twenty lung SABR VMAT plans in which the chest wall volume receiving 30 Gy or higher (V30) exceeded 30 mL were replanned by noncoplanar VMAT with opposite 15 degrees couch kicks. Dosimetric parameters including chest wall V30 and V40; lung V5, V10, V20, and mean dose; Paddick high-dose conformity index; intermediate-dose conformity index; and monitor units (MU) for each plan were used to evaluate the plan quality. The treatment time was also estimated by delivering the entire treatment. Two-sided paired t test was used to evaluate the difference of the dosimetric parameters between coplanar 1 arc (cVMAT1), coplanar 2 arcs (cVMAT2), and noncoplanar two arcs (nVMAT2) plans; differences with P < .05 were considered statistically significant. RESULTS: V30 and V40 for chest wall were reduced on average by 20% +/- 9% and 15% +/- 11% (mean +/- standard deviation) from cVMAT2 plans to nVMAT2 plans (P < .01 for both comparisons) and by 8% +/- 7% and 16% +/- 13% from cVMAT1 plans to cVMAT2 plans (P < .003 for both comparisons). The differences in lung mean dose were <0.2 Gy among cVMAT1, cVMAT2, and nVMAT2. There were no significant differences in lung V5, V10, and V20. On average, the number of MU increased 14% for nVMAT2 compared with cVMAT2. The Paddick high-dose conformity indexes were 0.88 +/- 0.03, 0.89 +/- 0.04, and 0.91 +/- 0.03, and intermediate-dose conformity indexes were 3.88 +/- 0.49, 3.80 +/- 0.44 and 3.51 +/- 0.38 for cVMAT1, cVMAT2, and nVMAT2, respectively. CONCLUSIONS: We found that noncoplanar VMAT plans are feasible, clinically practical to deliver, and significantly reduce V30 and V40 of chest wall without increasing lung dose. PMID- 29452869 TI - Three-dimensional printer-aided casting of soft, custom silicone boluses (SCSBs) for head and neck radiation therapy. AB - PURPOSE: Custom tissue compensators provide dosimetric advantages for treating superficial or complex anatomy, but currently available fabrication technology is expensive or impractical for most clinical operations and yields compensators that are difficult for patients to tolerate. We aimed to develop an inexpensive, clinically feasible workflow for generating patient-specific, soft, custom silicone boluses (SCSBs) for head-and-neck (HN) radiation therapy. METHODS AND MATERIALS: We developed a method using 3-dimensional printed parts for generating SCSBs for the treatment of HN cancers. The clinical workflow for generation of SCSBs was characterized inclusive of patient simulation to treatment in terms of resource time and cost. Dosimetric properties such as percentage depth dose and dose profiles were measured for SCSBs using GaF films. Comprehensive measurements were also conducted on an HN phantom. SCSBs were generated and used for electron or photon based radiation treatments of 7 HN patients with lesions at nose, cheek, eye, or ears. In vivo dose measurements with optically simulated luminescence dosimeters were performed. RESULTS: Total design and fabrication time from patient simulation to radiation treatment start required approximately 1 week, with fabrication constituting 1 to 2 working days depending on bolus surface area, volume, and complexity. Computed tomography and dosimetric properties of the soft bolus were similar to water. In vivo dose measurements on 7 treated patients confirmed that the dose deposition conformed to planned doses. Material costs were lower than currently available hard plastic boluses generated with 3-dimensional printing technology. All treated patients tolerated SCSBs for the duration of therapy. CONCLUSIONS: Generation and use of SCSBs for clinical use is feasible and effective for the treatment of HN cancers.

PMID- 29452874 TI - Quality of prostate cancer screening information on the websites of nationally recognized cancer centers and health organizations. AB - PURPOSE: The purpose of this study was to survey the accessibility and quality of prostate-specific antigen (PSA) screening information from National Cancer Institute (NCI) cancer center and public health organization Web sites. METHODS AND MATERIALS: We surveyed the December 1, 2016, version of all 63 NCI-designated cancer center public Web sites and 5 major online clearinghouses from allied public/private organizations (cancer.gov, cancer.org, PCF.org, USPSTF.org, and CDC.gov). Web sites were analyzed according to a 50-item list of validated health care information quality measures. Web sites were graded by 2 blinded reviewers. Interrater agreement was confirmed by Cohen kappa coefficient. RESULTS: Ninety percent of Web sites addressed PSA screening. Cancer center sites covered 45% of topics surveyed, whereas organization Web sites addressed 70%. All organizational Web pages addressed the possibility of false-positive screening results; 41% of cancer center Web pages did not. Forty percent of cancer center Web pages also did not discuss next steps if a PSA test was positive. Only 6% of cancer center Web pages were rated by our reviewers as "superior" (eg, addressing >75% of the surveyed topics) versus 20% of organizational Web pages. Interrater agreement between our reviewers was high (kappa coefficient = 0.602). CONCLUSION: NCI designated cancer center Web sites publish lower quality public information about PSA screening than sites run by major allied organizations. Nonetheless, information and communication deficiencies were observed across all surveyed sites. In an age of increasing patient consumerism, prospective prostate cancer patients would benefit from improved online PSA screening information from provider and advocacy organizations. Validated cancer patient Web educational standards remain an important, understudied priority. PMID- 29452875 TI - Use of expanders for bowel protection in pediatric pelvic tumor radiation therapy: 15 years of tolerance results. AB - PURPOSE: Bowel is often the dose-limiting organ in curative pelvic irradiation because of radiation enteritis when dose exceeds 40 to 45 Gy. To limit radiation enteritis, a silicone tissue-expander prothesis (STEP) connected to a subcutaneous self-sealing valve was prospectively used in children undergoing pelvic or abdominal radiation therapy. This study reports the 15-year long-term outcomes of this prospective series. METHODS AND MATERIALS: Between 1987 and 2008, 29 children from 3 Paris institutions received pelvic radiation therapy after surgical placement of a STEP in the pelvis. The median prescribed dose was 50.4 Gy (44.1-55 Gy) using 5 daily fractions of 1.8 Gy per week, except for 1 patient receiving 4 fractions of 2.5 Gy per week. The median treatment duration was 40 days (29-49 days). After 2000, computed tomography (CT) conformal 3 dimensional radiation therapy was used, and 12 patients had CT simulation. Four had CT before and after insertion of the STEP, enabling us to compare pre- and postprosthesis insertion bowel dose-volume histograms. Acute and late toxicities were captured using the Radiation Therapy Oncology Group or the National Cancer Institute Common Terminology Criteria for Adverse Events 4.0 scale. RESULTS: No patient experienced significant perioperative complications. Pre- and post-STEP insertion small bowel dose-volume histograms show significant reductions in small bowel: 51%, 45%, and 64%, respectively, in V10, V15, and V40 (Vx = irradiated volume by x Gy). Twenty-five patients (86%) completed their radiation therapy with no or minimal small bowel toxicity. One patient also treated with neutrons developed delayed grade 4 toxicities. The 15-year complication-free survival for those surviving was 70.3%. CONCLUSIONS: We report the long-term follow-up of STEP prosthesis insertion in children to reduce the small bowel volume in the radiation field. The acute and long-term tolerances were excellent. The STEP reduced the bowel dose over 40 Gy by 64%. PMID- 29452876 TI - Stereotactic body radiation therapy for high-riskprostate cancer: Not ready. PMID- 29452877 TI - The split hypoglossal nerve versus the cross-face nerve graft to supply the free functional muscle transfer for facial reanimation: A comparative study. AB - Long-standing cases of facial paralysis are currently treated with free functional muscle transfer. Several nerves are mentioned in the literature to supply the free muscle transfer. The aim of this study is to compare the split hypoglossal nerve and the cross-face nerve graft to supply the free functional muscle transfer in facial reanimation. Of 94 patients with long-standing, unilateral facial palsy, 49 were treated using the latissimus dorsi muscle supplied by the split hypoglossal nerve, and 45 patients were treated using the latissmus dorsi muscle supplied by healthy contralateral buccal branch of the facial nerve. The excursion gained by the free muscle transfer supplied by the split hypoglossal nerve (mean 19.20 +/- 6.321) was significantly higher (P value 0.001) than that obtained by the contralateral buccal branch of the facial nerve (mean 14.59 +/- 6.245). The split hypoglossal nerve appears to be a good possible option to supply the free vascularised muscle transfer in facial reanimation. It yields a stronger excursion in less time than the contralateral cross-face nerve graft. PMID- 29452878 TI - Combining Novel Renal Injury Markers with Delta Serum Creatinine Early after Cardiac Surgery and Risk-Stratification for Serious Adverse Outcomes: An Exploratory Analysis. AB - OBJECTIVE: To evaluate the prognostic utility of multiple novel urinary biomarkers of renal injury when used alone, in pair-wise combination with an early delta serum creatinine (DeltaSCr) term, and combined as a broad biomarker panel for the prediction of serious adverse outcomes that may reflect AKI in patients undergoing cardiac surgery. DESIGN: Post-hoc analysis of prospective observational study. SETTING: Academic medical center. PARTICIPANTS: 603 adults undergoing cardiac surgery. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Urinary cystatin-c, kidney injury molecule-1, chemokine (C-C motif) ligand 2 and interleukin-18 were measured at baseline and <1 hour, 3 hours and 18-24 hours after separation from cardiopulmonary bypass (CPB). DeltaSCr-initial was defined as the difference in SCr from baseline to first postoperative measure. The primary outcome of hospital mortality or renal replacement therapy occurred in 25 patients. Concordant elevation of any urinary biomarker measured 3 hours after CPB together with DeltaSCr-initial >=0 mg.dL-1 provided excellent early risk stratification for the primary outcome (OR >=15.1, 95% CI 4.1-55.4). Combining four urinary biomarkers together with DeltaSCr-initial and neutrophil gelatinase associated lipocalin, previously reported from the same cohort, to provide a 6 point AKI risk score enabled early identification of patients reaching the primary outcome (ROCAUC 0.86, 95% CI 0.79-0.92) with potentially useful sensitivity and specificity at varied cut-points. CONCLUSIONS: Combining novel urinary biomarkers of renal injury with a creatinine-based metric soon after cardiac surgery provided excellent prognostic utility for serious adverse outcomes. Future studies are required to confirm these findings and determine optimal biomarker combinations for cost-effective risk stratification.

PMID- 29452880 TI - Lucerne cast - LuCa: Functional conservative treatment of extra-articular fractures of the proximal phalanges of the fingers (with video). AB - Most extra-articular fractures of the proximal phalanges (P1) of the triphalangeal fingers can be treated conservatively with good results. Prerequisites for successful fracture treatment are intact soft tissue without any lesions of the extensor hood and stable initial fracture reduction. The key to functional conservative treatment of P1 fractures is to immobilize the metacarpophalangeal joints in flexion, resulting in equilibrium of flexor and extensor forces across the fracture site, which converts these inherently unstable fractures into relatively stable fractures. Precise initial application of the cast and regular follow-up of the patient is essential for successful treatment. By means of an instructional video, an overview of the equipment required is given, and the correct application of a Lucerne Cast is illustrated step-by-step. PMID- 29452881 TI - Tenosynovial chondromatosis of the wrist presenting with acute carpal tunnel syndrome: A case report. AB - We report a case of synovial chondromatosis of the wrist that manifested as acute carpal tunnel syndrome. The patient successfully underwent carpal tunnel release, tenosynovectomy and resection of dorsal and volar ossified bodies embedded in the tenosynovium overlying the wrist. Final histopathology confirmed the diagnosis of synovial chondromatosis. The patient's symptoms of pain, numbness, and paresthesia in a median nerve distribution resolved completely and the patient resumed full-time work in the service industry 4-weeks postoperatively with no functional limitations. This case highlights the importance of maintaining a broad differential in the approach to wrist pain and the role of magnetic resonance imaging in the diagnosis of synovial chondromatosis given its variable degree of ossification. PMID- 29452882 TI - Synthesis, characterisation and DNA intercalation studies of regioisomers of ruthenium (II) polypyridyl complexes. AB - Regioisomers of the functional group of the main ligand (L) on a series of [Ru(phen)2L]2+and [Ru(bpy)2L]2+ complexes, where phen is 1,10 phenanthroline and bpy is 2,2'-bipyridine, were synthesised to investigate the interaction with deoxyribonucleic acid (DNA) as potential therapeutics. UV-Vis binding titrations, thermal denaturation and circular dichroism were used to evaluate their interaction with DNA. The conclusions indicated the significance of the auxiliary ligand; especially 1,10-phenanthroline has on the binding constants (Kb). The systematic variation of auxiliary ligand(phen or bpy), and polypyridyl ligand (4 (1H-Imidazo[4,5-f][1,10]phenanthrolin-2-yl)benzonitrile (CPIP), 2-(4 formylphenyl)imidazo[4,5-f] [1,10] phenanthroline (FPIP), 2-(4 bromophenyl)imidazo[4,5-f][1,10]phenanthroline (BPIP) and 2-(4 nitrophenyl)imidazo[4,5-f] [1,10] phenanthroline (NPIP), split in terms of functional group change were investigated for DNA interaction. The CPIP analogues in particular were investigated for the regioisomerism (ortho, meta, para) effect of the nitrile group on the ligand. It was found that both the DNA interaction could be tailored through the systematic variation of the electronic nature of the individual auxiliary ligand and to a lesser extent the functional group and regioisomeric change. Preliminary cell line studies have been carried out to determine the selectivity of the complexes against cell lines such as A375 (Skin Cancer), HeLa (Cervical Cancer), A549 (Lung Cancer), Beas2B (Lung Normal Cell) and MCF-7 (Breast Cancer). Complexes which had strong DNA interactions in the binding studies have proven to be the most efficacious against certain cell lines. Establishing well-defined structure property relationships when looking at trends in spectroscopic properties and DNA binding will aid in the intelligent design of potential therapeutic complexes. PMID- 29452883 TI - Thiocarbonyl-bound metallonitrosyl complexes with visible-light induced DNA cleavage and promising vasodilation activity. AB - Nitric oxide has been involved in many key biological processes such as vasodilation, platelet aggregation, apoptosis, memory function, and this has drawn attention to the development of exogenous NO donors. Metallonitrosyl complexes are an important class of these compounds. Here, two new ruthenium nitrosyl complexes containing a thiocarbonyl ligand, with the formula cis [Ru(phen)2(L)(NO)](PF6)3 (phen = phenantroline, L = thiourea or thiobenzamide), were synthesized and characterized by electronic spectroscopy, FTIR, NMR, mass spectrometry and voltammetric techniques. Theoretical calculations using Density Functional Theory (DFT) and Time-dependent Density Functional Theory (TD-DFT) were also used and further supported the characterizations of these complexes. An efficient release of nitric oxide by blue light was validated using a NO/HNO probe: 2-(4-carboxyphenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide, known as cPTIO. Interestingly, the complex containing thiourea cleaved DNA even in the dark, while both complexes showed great DNA photocleavage activity in blue light. This process might work mainly through NO and hydroxyl radical production. Additionally, these complexes showed promising vasodilator activity, whose mechanism of action was investigated using N-Nitro-l-arginine methyl ester hydrochloride (L-NAME) and 1H-[1,2,4]Oxadiazolo[4,3-a]quinoxalin-1-one (ODQ) and compared to sodium nitroprusside. Both compounds were indeed NO-mediated heme dependent activators of soluble guanylate cyclase. Additionally, they did not show any significant cytotoxicity against cancer cell lines U87 and GBM02. Altogether, these results supported both complexes having potential pharmacological applications that deserve further studies. PMID- 29452884 TI - Water soluble glucose derivative of thiocarbohydrazone acts as ionophore with cytotoxic effects on tumor cells. AB - A novel water-soluble ionophore based on the thiocarbohydrazone moiety conjugated with glucose (GluTch) was synthesized through a simple two-step procedure. Structural elucidation was carried out in water solution by means of various spectroscopic techniques (NMR, UV-Vis, and CD), electrospray ionization mass spectrometry and density functional theory calculations. The flexible nature of the thiocarbohydrazone moiety of the new glycoderivative compound induced both different coordination motifs and stoichiometry towards copper and zinc. Cytotoxicity assays of the ligands on the human normal keratinocyte NCTC-2544, MDA-MB-231 breast cancer and PC-3 human prostate adenocarcinoma cell lines demonstrated that i) higher activity on cancer cells growth inhibition compared to a normal cell line; ii) the introduction of the glucose unit does not alter the cytotoxic activity of the underivatized ionophore ligand and iii) the presence of copper ion improves the activity of the thiocarbohydrazones. PMID- 29452885 TI - Somatolactogens and diabetic retinopathy. AB - IMPORTANCE: Diabetic retinopathy (DR) is one of the most common of all diabetic complications. The number of people with DR in the United States is expected to increase to 16 million by 2050. DR is the leading cause of blindness among working-age adults in many different countries, including the United States. In later DR stages, neovascularization is associated with extensive retinal capillary non-perfusion and vitreo-proliferation leading to retinal detachment. This neovascularization is orchestrated by an imbalance of growth factors in the retina from which somatolactogens (pituitary growth hormone, GH-N; placental growth hormone, GH-V; prolactin, PRL; and placental lactogen, PL, also referred as chorionic somatomammotropin, CSH), may play an important role. OBSERVATIONS: Somatolactogens are a group of hormones that share many structural and functional features. They are important for physiological changes in pregnancy, for adequate development of the fetus, and in the case of GH-N, for promoting growth after birth. GH-N is synthesized by the anterior pituitary, GH-V and PL are secreted by the placenta, whereas, PRL is synthesized by the anterior pituitary and uterine decidua. However, in recent years the expression of GH-N and PRL and their receptors have been detected in other tissues including the retina, acting as neuroprotective and pro-angiogenic agents. The relationship of GH-N and diabetic retinopathy (DR) was established many years ago when it was observed that its deficiency was related to regression of DR while an increase in serum levels of GH-N, GH-V, and PL promoted DR. While more studies are needed to define the potential implications of GH-V and PL in DR pathogenesis, it has been demonstrated that GH-N and PRL participate in DR by enhancing neovascularization. Some PRL isoforms, however, have shown an anti-angiogenic activity rather than pro-angiogenesis and appears to be PRL's main role in the regulation of retinal vasculature. CONCLUSIONS: Somatolactogens are a group of hormones with a significant role in neuroprotection and angiogenesis regulation in the eye. Understanding the mechanisms of angiogenesis regulation by somatolactogens will potentially lead to the development of new drugs for DR. PMID- 29452886 TI - Shifting the IGF-axis: An age-related decline in human tear IGF-1 correlates with clinical signs of dry eye. AB - OBJECTIVE: The human corneal epithelium expresses both the insulin-like growth factor type 1 receptor (IGF-1R) and the IGF-1R/insulin receptor (INSR) hybrid. Despite the previous identification of IGF-1 in human tear fluid, little is known regarding the regulation of IGF-1 in tear fluid and its role in corneal epithelial homeostasis. In the present study, we investigated the impact of biological parameters on the concentration of human tear levels of IGF-1. DESIGN: Tear levels of IGF-1 were measured in 41 healthy, human volunteers without any reported symptoms of dry eye. All volunteers underwent standard biomicroscopic examination of the cornea and tear film. In a subgroup of volunteers, corneal staining with sodium fluorescein, tear film break up time and tear production using a Schirmer's test strip were measured to assess clinical signs of dry eye. Tears were collected from the inferior tear meniscus using glass microcapillary tubes and IGF-1 levels were measured using a solid phase sandwich ELISA. RESULTS: Tear levels of IGF-1 were highest in young adults and significantly decreased in older adults (P = 0.003). There were no differences in tear IGF-1 between males and females (P = 0.628). Tear IGF-1 levels were correlated with tear film break up time (R = 0.738) and tear production (R = 0.826). CONCLUSIONS: These data indicate that there is a progressive decline in tear IGF-1 due to aging that is associated with clinical signs of dry eye. This effect is likely due to age related changes in the lacrimal gland. PMID- 29452887 TI - Protein Intake and Long-term Change in Glomerular Filtration Rate in the Jackson Heart Study. AB - OBJECTIVE: Dietary protein intake could have deleterious renal effects in populations at risk for chronic kidney disease. Here, we examined whether higher protein intake (>=80th percentile of energy from protein) is associated with decline in kidney function and whether this decline varies by diabetes status. DESIGN: Observational cohort study. SUBJECTS AND SETTINGS: Participants were African-Americans (n = 5,301), who enrolled in the Jackson Heart Study between 2000 and 2004. METHODS: Dietary intake was assessed using a validated food frequency questionnaire at baseline, and serum creatinine was measured at baseline (visit 1) and 8 years later (visit 3). Estimated glomerular filtration rates (eGFRs) at baseline and follow-up were computed using the chronic kidney disease epidemiology collaboration equation. MAIN OUTCOME MEASURE: The change in eGFR was computed by subtracting eGFR at visit 1 from that at visit 3. RESULTS: Of 3,165 participants with complete data, 64% were women, 57% had hypertension, and 19% had diabetes. The median (25th, 75th percentile) percent energy intake from protein was 14.3 (12.4, 16.4), comparable to that reported for the general US population (15% of energy). During a median (25th, 75th percentile) follow-up of 8.0 (7.4, 8.3) years, eGFR declined by 10.5% from a mean (SD) of 97.4 (17.5) to 86.9 (21.3) mL/min/1.73 m2. In the fully adjusted model, consumption of protein as percent of energy intake in lowest and highest quintiles was associated with decline in eGFR among diabetic subjects. The analysis of variance with a robust variance estimator was used to determine whether long-term change in eGFR significantly varies by protein intake. CONCLUSIONS: Our results show that, among African-Americans with diabetes, higher protein intake as a percent of total energy intake is positively associated with greater decline in eGFR in analyses that accounted for risk factors for kidney disease. PMID- 29452888 TI - Could Low-Protein Diet Modulate Nrf2 Pathway in Chronic Kidney Disease? AB - Oxidative stress and inflammation are common findings in chronic kidney disease (CKD) patients, and they are directly linked to clinical outcomes such as protein energy wasting and cardiovascular disease. Nuclear factor-erythroid 2-related factor 2 (Nrf2) is the master regulator of antioxidant genes, regulating the expression of detoxifying enzymes of phase II and antioxidant responses. Furthermore, Nrf2 can also regulate anti-inflammatory cellular responses, by inhibiting nuclear factor kappa B activity (transcription factor that promotes inflammation). Therefore, modulating Nrf2 can be a new therapeutic approach to reduce inflammation and oxidative stress in CKD. Low-protein diet (LPD) prescribed for nondialysis CKD patients presents numerous benefits already well established, including reduction of inflammation and oxidative stress. However, there is no available data regarding the relationship between LPD and Nrf2 modulation in these patients. This review aims to discuss the impact, if any, of LPD on Nrf2 expression, in nondialysis CKD patients. PMID- 29452889 TI - Anthropometric and Biochemical Determinants of Estimated Glomerular Filtration Rate in a Large Cohort of Obese Children. AB - OBJECTIVE: We aimed to investigate which clinical and metabolic factors could influence the estimated glomerular filtration rate (eGFR) levels, evaluating a large population of obese children without suspect of primary kidney disease. DESIGN: Retrospective, cross-sectional study. SETTING: Pediatric university department. SUBJECTS: We enrolled 2,957 obese children and adolescents consecutively attending our department between January 2000 and 2017. Inclusion criteria were body mass index (BMI) > 95th percentile and eGFR > 90 mL/min/1.73 m2. Exclusion criteria were secondary forms of obesity, eGFR < 90 mL/min/1.73 m2, proteinuria/hematuria at urine dipstick, or consumption of any medication. INTERVENTIONS: Weight, waist circumference, height, waist to height ratio (W/Hr), BMI-standard deviation score (SDS), pubertal stage, systolic blood pressure (SBP) and diastolic blood pressure (DBP), duration of obesity, insulin, eGFR, and homeostasis model assessment (HOMA-IR) were obtained. A general linear model was performed for a multiple variable analysis. MAIN OUTCOME MEASURE: The population was divided in tertiles for BMI-SDS, W/Hr, SBP- and DBP-SDS, HOMA-IR, and duration of obesity. We compared eGFR levels among these tertiles. RESULTS: The eGFR levels significantly increased across both BMI-SDS and W/Hr tertiles. Conversely the eGFR levels significantly decreased across SBP-SDS, HOMA-IR, and duration of obesity tertiles. No significant differences in eGFR levels across DBP-SDS tertiles were detected. Pubertal patients presented significantly lower eGFR values compared with prepubertal patients. A general linear model for eGFR variance including as covariates W/Hr, HOMA-IR, duration of obesity, pubertal stage, BMI-SDS, and SBP-SDS (model R2 39.7%; model P < .00001) was performed. It confirmed a direct association of eGFR values with BMI-SDS and an indirect association with HOMA-IR, duration of obesity, pubertal stage, and SBP-SDS. CONCLUSIONS: We showed a positive correlation of eGFR with both BMI-SDS and a negative one with SBP-SDS, HOMA-IR, pubertal stage, and duration of obesity. The duration of obesity was the variable most significantly associated to eGFR levels. PMID- 29452890 TI - Editorial. PMID- 29452891 TI - Effect of topical application of 2% lidocaine gel on corneal sensitivity of clinically normal equine eyes. AB - OBJECTIVE: To assess the degree and duration of corneal anaesthesia provided by topical application of a non-ophthalmic 2% lidocaine gel in horses. STUDY DESIGN: Experimental, 'blinded', randomized prospective study. ANIMALS: Twelve adult horses without relevant ocular abnormalities. METHODS: Baseline corneal touch threshold (CTT) measurements were obtained bilaterally by use of a Cochet-Bonnet aesthesiometer just prior to topical treatment. A volume of 0.2mL of 2% lidocaine gel was administered in one randomly selected eye and the same volume of a viscous lubricant in the other eye to serve as control. The CTT value was measured on both eyes 5, 10, 20, 30, 45, 60, 75 and 90 minutes after drug application. The potential for local adverse effects following lidocaine gel application was also evaluated. RESULTS: Mean CTT baseline measurements were not significantly different (p>0.05) between the control eyes (3.41+/-0.56cm) and those subsequently treated with the lidocaine gel (3.50+/-0.64cm). In control eyes, no significant changes in corneal sensitivity (p>0.05) occurred over time during the study period. By contrast, a marked reduction in corneal sensitivity was observed after lidocaine application, with mean CTT values significantly lower (p<0.001) than those of the control eyes from 5 to 75 minutes. A steady state maximal corneal anaesthesia was present from 10 to 45 minutes after lidocaine gel application with mean CTT values ranging from 0.21 to 0.45cm. Corneal epithelial irregularities were detected in three lidocaine-treated eyes, but spontaneous resolution occurred within 24hours. CONCLUSIONS AND CLINICAL RELEVANCE: Deep and sustained corneal anaesthesia is achieved after application of 2% lidocaine gel to the equine eye, with minimal changes in the corneal epithelium. It might be useful for minor ophthalmic surgeries performed in the standing sedated horse. PMID- 29452892 TI - Association of breastfeeding duration with dyslipidemia in women aged over 20 years: Korea National Health and Nutrition Examination Survey 2010-2014. AB - BACKGROUND: The prevalence of dyslipidemia, particularly hypercholesterolemia, has been reported to increase after pregnancy and menopause in Korea. This suggests the importance of the management of dyslipidemia in women for preventing cardiovascular diseases. OBJECTIVE: This study aimed to examine the association of breastfeeding with 5 subtypes of dyslipidemia in Korean women aged over 20 years, by using the nationally representative Korea National Health and Nutrition Examination Survey 2010-2014. METHODS: Ordinary least square regression and ordered logistic regression analyses were used to determine the association between breastfeeding duration and dyslipidemia. RESULTS: The likelihood of having low-density lipoprotein cholesterol (LDL-C) disorder decreased by 16% in the group that breastfed for more than 24 months (odds ratio, 0.84; 95% confidence interval, 0.75-0.95) compared with the group that did not breastfeed. The likelihood of having non-high-density lipoprotein cholesterol (non-HDL-C) disorder was significantly reduced by 25% when the breastfeeding duration was more than 24 months (odds ratio, 0.75; 95% confidence interval, 0.64-0.87). The tendency toward developing disorders of total cholesterol (TC), LDL-C, and non HDL-C decreased as the duration of breastfeeding increased, particularly among women aged 30-39 years. CONCLUSION: Breastfeeding duration was negatively correlated with dyslipidemia in terms of TC, LDL-C, non-HDL-C, and triglycerides. Long-term breastfeeding was associated with the prevalence of dyslipidemia-TC, LDL-C, non-HDL-C, and TG disorders, in particular. PMID- 29452893 TI - A novel mutation in GPIHBP1 causes familial chylomicronemia syndrome. AB - Familial chylomicronemia syndrome is characterized by severe elevation in serum triglycerides and an increased risk of acute pancreatitis. Although familial chylomicronemia syndrome is mainly caused by mutations in the lipoprotein lipase (LPL) gene, few causal mutations in other genes (ie, APOC2, APOA5, LMF1, and GPIHBP1) have also been reported. In this case report, we present the discovery of a novel mutation in the glycosylphosphatidylinositol-anchored high-density lipoprotein-binding protein 1 (GPIHBP1) gene and discuss its pathogenicity through a familial segregation study. PMID- 29452894 TI - Bioprocessing automation in cell therapy manufacturing: Outcomes of special interest group automation workshop. AB - Phacilitate held a Special Interest Group workshop event in Edinburgh, UK, in May 2017. The event brought together leading stakeholders in the cell therapy bioprocessing field to identify present and future challenges and propose potential solutions to automation in cell therapy bioprocessing. Here, we review and summarize discussions from the event. Deep biological understanding of a product, its mechanism of action and indication pathogenesis underpin many factors relating to bioprocessing and automation. To fully exploit the opportunities of bioprocess automation, therapeutics developers must closely consider whether an automation strategy is applicable, how to design an 'automatable' bioprocess and how to implement process modifications with minimal disruption. Major decisions around bioprocess automation strategy should involve all relevant stakeholders; communication between technical and business strategy decision-makers is of particular importance. Developers should leverage automation to implement in-process testing, in turn applicable to process optimization, quality assurance (QA)/ quality control (QC), batch failure control, adaptive manufacturing and regulatory demands, but a lack of precedent and technical opportunities can complicate such efforts. Sparse standardization across product characterization, hardware components and software platforms is perceived to complicate efforts to implement automation. The use of advanced algorithmic approaches such as machine learning may have application to bioprocess and supply chain optimization. Automation can substantially de-risk the wider supply chain, including tracking and traceability, cryopreservation and thawing and logistics. The regulatory implications of automation are currently unclear because few hardware options exist and novel solutions require case-by case validation, but automation can present attractive regulatory incentives. PMID- 29452895 TI - The ultrasonography evaluation of talar dysplasia as a potential prognostic factor for predicting the course and outcomes of clubfoot deformity treatment using Ponseti technique. AB - OBJECTIVE: The aim of this study was to assess the role of sonographic evaluation of Talar dysplasia in predicting the outcome of standard Ponseti method in the treatment of clubfoot deformity. METHODS: A total 23 children (15 boys and 8 girls; mean age: 18.2 +/- 5.4 days (8-32)) who underwent Ponseti treatment were included in the study. Before the treatment, maximal talus length of affected and non-affected feet were measured by US and relative talar dysplasia ratio (RTDR) was calculated. The patients were categorized 2 groups according to RTDR: group A - mild and group B - severe deformity. Pirani score was used for clinical evaluation. The groups were compared in terms of number of the applied casts, need of percutaneous tenotomy of Achilles tendon (AchT) and frequency of deformity recurrence. RESULTS: Pirani score was 4.46 for population (4.33 for group A; 4.54 for group B). Number of casts significantly differed between groups (p < 0.001) and positive correlation was found (r = 0.851, p < 0.001). AchT was performed in 56% cases for group A and in 86% cases for group B; no statistically significant difference was obtained (p = 0.162). Recurrence occurred in 2 patients belonging to group B without significant difference compared to group A (p = 0.502). CONCLUSION: Talar dysplasia assessment appeared as a promising prognostic factor for predicting the outcome of the Ponseti technique in treatment of clubfoot deformity.

PMID- 29452896 TI - Do subscapularis tears really result in superior humeral migration? AB - OBJECTIVES: The aim of this study was to analyse the effect of subscapularis tear on superior humeral excursion (SHE) and acromiohumeral distance (AHD). The hypothesis was that subscapularis tears do not result in superior humeral excursion. METHODS: Patients who underwent shoulder arthroscopy between August of 2011 and 2015 were reevaluated. Those with isolated Bankart lesion were used as control group and included in the Group 1, isolated full-thickness supraspinatus tear in the Group 2, isolated subscapularis tear in the Group 3, and combined subscapularis and supraspinatus tear in the Group 4. The mean SHE and AHD measurements on magnetic resonance imaging of these groups were compared to reveal any difference in superior humeral migration (SHM). RESULTS: There were 30 patients in each group. The mean age of Group 1 (26.44 +/- 8.34) was younger than the other 3 groups. The mean AHD and SHE were higher in Group 1 and 3 (Mean AHD: 12.89 +/- 2.24 and 12.28 +/- 1.9, respectively. Mean SHE: -3.2 +/- 0.99 and -2.78 +/- 0.64, respectively) than Group 2 and 4 (Mean AHD: 6.2 +/- 1.78 and 6.16 +/- 1.52, respectively. Mean SHE: 0.72 +/- 0.65 and 1.24 +/- 0.63, respectively). The AHD and SHE were strongly correlated with each other (Pearson correlation coefficient = 0.184). The inter-observer and intra-observer correlation of the measurements of SHE on MRI were excellent with intraclass correlation coefficient of 0.95 and 0.94, respectively. CONCLUSION: Subscapularis tears do not lead to SHM and subacromial impingement. However, superior rotator cuff tears can still lead to SHM and subacromial impingement even when subscapularis tendon is intact. LEVEL OF EVIDENCE: Level III, diagnostic study. PMID- 29452898 TI - Transcriptional and epigenetic regulation of innate-like T lymphocyte development. AB - Invariant Natural Killer T (iNKT) cells are a heterogeneous innate T cell population that recognizes lipid antigens. Despite the monospecific nature of their T cell receptor, iNKT cells differentiate into stable sublineages during thymic development, before foreign antigen encounter. How iNKT cell subsets acquire and maintain their functional programs is a central question in innate lymphocyte biology. Global transcriptional and epigenetic profiling of iNKT subsets has provided insights into the internal wiring of these subsets that defines their identity. Comparison of the iNKT transcriptional programs with those of other adaptive and innate lymphocyte lineages revealed common core regulatory circuits that may dictate effector functions. In this review, we summarize recent advances on the molecular mechanisms involved in iNKT cell development. PMID- 29452899 TI - Influence of dominant- as compared with nondominant-side symptoms on Disabilities of the Arm, Shoulder and Hand and Western Ontario Rotator Cuff scores in patients with rotator cuff tendinopathy. AB - HYPOTHESIS AND BACKGROUND: The Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire and the Western Ontario Rotator Cuff (WORC) index are 2 widely used patient-reported questionnaires in individuals with rotator cuff (RC) tendinopathy. In contrast to the WORC index, for which the items are specific to the affected shoulder, the items of the DASH questionnaire assess the ability to perform activities regardless of the arm used. The objective of this study is to determine whether scores on the DASH questionnaire and WORC index are affected if the symptoms are on the dominant or nondominant side in individuals with RC tendinopathy. Given the number of items that can be influenced by dominance, the hypothesis is that DASH scores will be impacted by the side of the symptoms. METHODS: Individuals with RC tendinopathy (N = 149) completed questions on symptomatology and hand dominance, the DASH questionnaire, and the WORC index. Differences in total scores (independent t test) and single items (Wilcoxon rank sum test) were compared between groups of participants with dominant-side symptoms and those without dominant-side symptoms. RESULTS: No significant differences were observed for WORC or DASH total scores when comparing participants with and without symptoms on their dominant side. Single-item comparison revealed more items being affected by symptom side on the DASH questionnaire (6 of 30 items) than on the WORC index (2 of 21 items). CONCLUSIONS: The side of the symptoms does not influence the DASH and WORC total scores, as there are no systematic differences between individuals with and without symptoms in their dominant shoulder. However, the presence of dominant symptoms does influence item scores more on the DASH questionnaire than on the WORC index. PMID- 29452900 TI - Prevalence and correlates of hypertension-outcome of a free medical screening in Oke-Ogun area of Oyo state, Nigeria, West Africa. AB - Literature abounds on prevalence of hypertension in Nigeria and urban areas of Oyo state but none in Oke-Ogun geopolitical zone, which constitutes 10 local governments of the 33 in Oyo state, despite the fact that they have high genetic and environmental predisposition to developing high blood pressure. The purpose of the study was to determine the prevalence of high blood pressure and associated risk factors among indigenes of Oke-ogun, Oyo state. A total of 10,000 respondents were recruited using proportionate sampling techniques. Hypertension was defined according to Joint National Committee-8 criteria. The fasting plasma glucose of the respondents were classified as normal (<=6 mmol/L), prediabetes (6.1-6.9 mmol/L), and diabetes (>=7 mmol/L). Body mass index was calculated as weight (kg)/height (m2) and classified as malnutrition/underweight (<16-18.49), normal (18.5-24.9), overweight (25-29.9), and obese (30->=40). Data were analyzed using descriptive statistics, Chi-square and binary logistic regression tests at P < .05. The mean systolic and diastolic blood pressure was 138 +/- 27.81 and 86.13 +/- 14.39 respectively. The overall prevalence of hypertension was 38.5%. 64.1% were diabetics. 63.4% had no formal education. Majority (82.95%) earned less than N18,000 ($59) per month. 43.3% had family history of hypertension. There is high prevalence of hypertension among the people of Oke-ogun, in Oyo state. Their low socioeconomic status, low educational background, malnutrition, and genetic predisposition were identified risk factors. PMID- 29452903 TI - Extracellular vesicles as key mediators of plant-microbe interactions. AB - Extracellular vesicles (EVs) are lipid compartments capable of trafficking proteins, lipids, RNA and metabolites between cells. Plant cells have been shown to secrete EVs during immune responses, but virtually nothing is known about their formation, contents or ultimate function. Recently developed methods for isolating plant EVs have revealed that these EVs are enriched in stress response proteins and signaling lipids, and appear to display antifungal activity. Comparison to work on animal EVs, and the observation that host-derived small interfering RNAs and microRNAs can silence fungal genes, suggests that plant EVs may also mediate trans-kingdom RNA interference. Many fundamental questions remain, however, regarding how plant EVs are produced, how they move, and if and how they are taken up by target cells. PMID- 29452902 TI - Retina dose as a predictor for visual acuity loss in 106Ru eye plaque brachytherapy of uveal melanomas. AB - BACKGROUND AND PURPOSE: To evaluate the retina dose as a risk factor associated with loss of visual acuity (VA) in 106Ru plaque brachytherapy. MATERIAL/METHODS: 45 patients receiving 106Ru plaques brachytherapy (median follow-up 29.5 months) were included in this study. An in-house developed treatment planning system with Monte Carlo based dose calculation was used to perform treatment planning and dose calculation. Risk factors associated with loss of VA were evaluated using the Cox proportional hazards models, Kaplan-Meier estimates and Pearson correlation coefficients. RESULTS: A significant correlation was found between VA loss and mean (r = 0.49, p = 0.001) and near maximum (r = 0.47, p = 0.001) retina dose D2% and tumor basal diameter (r = 0.50, p < 0.001). The Kaplan-Meier and Cox proportional hazards model yielded a significantly higher risk for VA loss (>0.3Snellen) for patients receiving a maximum dose of >500 Gy (p = 0.002). A Cox multivariate analysis including the macula dose (p = 0.237) and basal diameter (p = 0.791) showed that a high maximum retinal dose is the best risk factor (p = 0.013) for VA loss. CONCLUSION: The study showed that retina dose (D2% and Dmean) is a suitable predictor for VA loss. PMID- 29452901 TI - Improved cost-effectiveness of short-course radiotherapy in elderly and/or frail patients with glioblastoma. AB - BACKGROUND AND PURPOSE: Short-course radiotherapy (25 Gy in five fractions) was recently shown in a randomized phase III trial to be non-inferior to 40 Gy in 15 fractions in elderly and/or frail patients with glioblastoma multiforme. This study compared the cost-effectiveness of the two regimens. MATERIAL AND METHODS: The direct unit costs of imaging, radiotherapy (RT), and dexamethasone were collected from the five primary contributing countries to the trial, constituting the data of 88% of all patients. Effectiveness was measured by the restricted mean overall survival (RMOS) and progression free survival (RMPFS). The incremental cost-effectiveness ratio (ICER) was calculated. Indirect costs were also estimated for comparison. RESULTS: The median OSs for the short-course and commonly used RTs were 8.2 (95% confidence interval [CI] 6.1-10.3) and 7.7 (95% CI 5.5-9.9) months, respectively (log rank p = 0.340). Median PFSs were also not different (p = 0.686). The differences in the RMOS and the ICER, however, were +0.11 life-years and -$3062 United States dollars (USD) per life-year gained, respectively. The differences in the RMPFS and the ICER were +0.02 PFS and $17,693 USD, respectively. CONCLUSION: The ICER of -$3062 per life-year gained and -$17,693 per PFS gained indicates that the short-course RT is less costly compared to the longer RT regimen. PMID- 29452904 TI - Leaf nodule symbiosis: function and transmission of obligate bacterial endophytes. AB - Various plant species establish intimate symbioses with bacteria within their aerial organs. The bacteria are contained within nodules or glands often present in distinctive patterns on the leaves, and have been used as taxonomic marker since the early 20th century. These structures are present in very diverse taxa, including dicots (Rubiaceae and Primulaceae) and monocots (Dioscorea). The symbionts colonize the plants throughout their life cycles and contribute bioactive secondary metabolites to the association. In this review, we present recent progress in the understanding of these plant-bacteria symbioses, including the modes of transmission, distribution and roles of the symbionts. PMID- 29452905 TI - Voiding school as a treatment for daytime incontinence or enuresis: Assessing the effectiveness of intervention by measuring changes in wetting episodes. AB - BACKGROUND: Most urotherapy interventions are planned for children with daytime incontinence or symptoms, and are based on individual education. This study conducted a voiding school (VS) program with groups of 4-6 children with daytime incontinence or enuresis with or without daytime symptoms. OBJECTIVE: The aim of this quasi-experimental study with a one-group pretest-posttest design was to assess the effectiveness of the VS intervention for treating children's daytime incontinence or enuresis. MATERIALS AND METHODS: Sixty-nine 6-12-year-old children with incontinence classified as treatment resistant participated in the VS at an outpatient clinic. Based on a power analysis, a sample of 52 participants was required. The VS involved two whole-day group visits 2 months apart. The educational content of the intervention was based on the International Children's Continence Society's standards for urotherapy, and was delivered with child-oriented teaching methods, including group discussions with peers. The primary outcome measure was the number of dry days and nights. The amount of wetting was also estimated, and the frequency of voiding measured. Data were collected with 1-week voiding diaries before and after each visit. Changes in dependent variables between four measurement points was measured by using repeated measures variance analysis. The long-term effectiveness was evaluated from patient records concerning 3-month follow-up phone calls or other contacts 8 18 months after the VS. RESULTS: Fifty-eight children, 34 girls and 24 boys, completed the study. Twelve children had daytime incontinence, 18 had enuresis, and 28 had both. The number of dry days increased from a mean of 3.5-5.3 (P < 0.001), and the number of dry nights increased from a mean of 2.4-3.9 (P < 0.001) (Summary table). Thirteen (22%) children became completely dry. Three of them had daytime incontinence, five enuresis, and five both. Twenty-four out of 40 (60%) children with daytime incontinence, and 23 out of 46 (50%) children with enuresis showed >=50% decrease in wetting episodes. The amount of wetting reduced, but the voiding frequency remained unchanged based on the voiding diaries. Twenty-two (45%) of the children were completely dry (six had daytime incontinence, nine enuresis, and seven both), and 16 (39%) showed further improvement, but eight (16%) children remained unchanged 8-18 months after the VS. CONCLUSIONS: Voiding school (VS) was an effective intervention for treating both daytime incontinence and nocturnal enuresis in children who had not benefited from standard treatment and were classified as treatment resistant. PMID- 29452906 TI - Extracranial arterial wall volume is increased and shows relationships with vascular MRI measures in idiopathic Parkinson's disease. AB - OBJECTIVE: Idiopathic Parkinson's disease (IPD) is the second most common neurodegenerative disorder, often complicated by dementia. Cardiovascular risk factors and spontaneous cerebral emboli (SCE) are strongly associated with Alzheimer's (AD) and vascular dementia (VaD). We measured SCE in the middle cerebral artery and arterial wall volume in the extracranial arteries in patients with IPD and controls, and explored the relationships with structural and physiological MRI brain neurovascular measures. PATIENTS AND METHODS: Arterial wall volume over 2cm of the axillary and internal carotid arteries (ICA) bilaterally was measured by 3-D tomographic ultrasound in 15 IPD patients and 16 age/gender matched controls. SCE were counted by Transcranial Doppler (TCD) using international consensus criteria. Venous to arterial circulation shunting (v aCS), usually through a patent foramen ovale (PFO), was measured using a TCD technique with intravenous microbubble contrast. Structural and physiological MRI brain neurovascular measures, acquired separately, comprised white matter lesion volume (WMLV), cerebral blood flow (CBF) and arterial arrival time (AAT). RESULTS: Mean (95% CI) axillary and ICA wall volume was higher in IPD patients at 523 mm3 (446, 600) and 455 mm3 (374, 536) respectively compared with 412 mm3 (342, 483) and 408 mm3 (362, 454) in controls being significant for the axillary artery (p = 0.04). Cerebral WMLV was related to mean arterial wall volume for both axillary (r = 0.555, p = 0.009) and ICA (r = 0.559, p = 0.026) in all participants. SCE were detected in four IPD patients and three controls (p = 1.00). Two IPD patients and three controls were positive for a v-aCS equivalent to PFO (p = 0.477). CONCLUSION: Although frequent in AD and VaD, neither SCE nor v-aCS were associated with IPD. This is the first study to demonstrate arterial wall volume is increased in IPD and relates to WMLV.

AB - AIM: The purpose of this study was to evaluate the effects of the rapid palatal expansion (RPE) on posture and gait analysis in subjects with maxillary transverse discrepancies. MATERIAL AND METHODS: Forty-one patients between 6 and 12 years were divided into 3 groups: 10 control subjects (Cs), 16 patients with unilateral posterior crossbite (CbMono), 15 patients with maxillary transverse discrepancy and no crossbite (Nocb). Every subject underwent gait analysis and posturographic examination in order to evaluate the presence of balance alterations before (T0) and after (T4) RPE application. The examinations were performed through a six-cameras stereophotogrammetric system (60-120Hz, BTS S.p.A.) synchronized with two force plates (FP4060, Bertec Corp.). Romberg test was performed on a force plate, and the statokinesiogram and joint kinematics were evaluated. One-way Anova was performed among the variables after evidence of normal distribution (Levene's test for equality of variances) and Kruskal-Wallis test (P<0.05), in order to compare the three groups of subjects. While paired t test was performed, or Kruskal-Wallis test, instead when comparing pre- and post RPE application within the same group of subjects (P<0.05). Tamane T2 or Bonferroni correction was applied where needed. RESULTS: The posturographic analysis reveal significant differences across the 3 population: 95% power frequency in medio-lateral and antero-posterior direction in T0, median frequency in medio-lateral direction in T0, mean power frequency in medio-lateral direction in T0. Significant differences were also registered in the three-dimensional joints kinematics variables, mainly between Cs and Cbmono in T0 and T4 and between Cbmono and Nocb in T4. CONCLUSIONS: A detectable correlation between dental occlusion and body posture is shown in this study that confirms another benefit of the RPE. This was mainly revealed in the dynamic posture where modifications at the mandibular level affect the whole body. PMID- 29452909 TI - ? PMID- 29452910 TI - Three-dimensional evaluation of airway volume changes in two expansion activation protocols. AB - The purpose of this study was to evaluate the airway volume changes associated with rapid maxillary expansion (RME) protocols using different activation rates. A sample of forty RME treated cases was classified into two groups according to the rate of RME activation (Group A: 0.8mm per day and Group B: 0.5mm per day). Three-dimensional images were obtained for each case before and three months after expansion. Dolphin imaging software was used to identify landmarks and calculate airway volumes. Intraclass correlation coefficient was used to confirm reliability and Wilcoxon signed rank tests were used for comparison between the initial and final measurements within each group and between groups. Significant increase in the nasal cavity volume for both groups was observed (P<0.0001 and P=0.001 for groups A and B respectively). The increase in nasopharynx volume was significant in the group with a more rapid activation rate (P=0.0006). Significant differences between the two groups in post-treatment changes were detected in the nasal cavity volume (P<0.0001), nasopharynx volume (P=0.0035), and soft palate area (P=0.0081). A more rapid activation rate results in a higher volume increase for the nasal cavity and nasopharynx than a slower activation rate. PMID- 29452911 TI - ?

PMID- 29452913 TI - Photo-immobilized EGF chemical gradients differentially impact breast cancer cell invasion and drug response in defined 3D hydrogels. AB - Breast cancer cell invasion is influenced by growth factor concentration gradients in the tumor microenvironment. However, studying the influence of growth factor gradients on breast cancer cell invasion is challenging due to both the complexities of in vivo models and the difficulties in recapitulating the tumor microenvironment with defined gradients using in vitro models. A defined hyaluronic acid (HA)-based hydrogel crosslinked with matrix metalloproteinase (MMP) cleavable peptides and modified with multiphoton labile nitrodibenzofuran (NDBF) was synthesized to photochemically immobilize epidermal growth factor (EGF) gradients. We demonstrate that EGF gradients can differentially influence breast cancer cell invasion and drug response in cell lines with different EGF receptor (EGFR) expression levels. Photopatterned EGF gradients increase the invasion of moderate EGFR expressing MDA-MB-231 cells, reduce invasion of high EGFR expressing MDA-MB-468 cells, and have no effect on invasion of low EGFR expressing MCF-7 cells. We evaluate MDA-MB-231 and MDA-MB-468 cell response to the clinically tested EGFR inhibitor, cetuximab. Interestingly, the cellular response to cetuximab is completely different on the EGF gradient hydrogels: cetuximab decreases MDA-MB-231 cell invasion but increases MDA-MB-468 cell invasion and cell number, thus demonstrating the importance of including cell microenvironment interactions when evaluating drug targets.

PMID- 29452915 TI - Effect of male body mass index on assisted reproduction treatment outcome: an updated systematic review and meta-analysis. AB - Men with a body mass index (BMI) of 30 or over are more likely to have reduced fertility and fecundity rates. This systematic review and meta-analysis evaluated the effect of male BMI on IVF and intracytoplasmic sperm injection (ICSI) outcome. An electronic search for published literature was conducted in MEDLINE and EMBASE between 1966 and November 2016. Outcome measures were clinical pregnancy rates (CPR) and live birth rates (LBR) per IVF or ICSI cycle. Eleven studies were identified, including 14,372 cycles; nine reported CPR and seven reported LBR. Pooling of data from those studies revealed that raised male BMI was associated with a significant reduction in CPR (OR 0.78, 95% CI 0.63 to 0.98, P = 0.03) and LBR (OR 0.88, 95% CI 0.82 to 0.95, P = 0.001) per IVF-ICSI treatment cycle. Male BMI could be an important factor influencing IVF-ICSI outcome. More robust studies are needed to confirm this conclusion using standardized methods for measuring male BMI, adhering to the World Health Organization definitions of BMI categories, accounting for female BMI, IVF and ICSI cycle characteristics, including the number of embryos transferred and embryo quality, and use the live birth rate per cycle as primary outcome.

AB - OBJECTIVES: The purpose of this study is to determine if stable, well-appearing, drowning patients who have normal age-adjusted vital signs and pulse oximetry upon arrival to the emergency department may be safely discharged without a prolonged observation period. METHODS: Medical records were retrospectively reviewed for drowning patients presenting to a single pediatric emergency department from 1995 to 2014. Data were collected on vital signs and pulse oximetry at presentation, chest x-ray results, disposition and complications for each encounter. Patients were identified as having either normal or abnormal initial vital signs and pulse oximetry, and were compared based on disposition and complication rates. RESULTS: Two hundred seventy-six records were initially evaluated and 91 were excluded. Thirty-six percent had normal age-adjusted vital signs upon arrival. Patients with abnormal temperature, respiratory rate or pulse oximetry, as well as those with any abnormal initial cardiopulmonary physical exam findings, abnormal mental status, or chest radiograph findings, were more likely to be admitted to the hospital. Eight patients developed respiratory complications after presentation to the emergency department. Those with abnormal pulse oximetry readings on arrival were more likely to develop complications. Only two patients who developed complications had initially normal vital signs and each had evidence of clinical deterioration within 1h of arrival. CONCLUSIONS: The overall complication rate in initially stable, well-appearing drowning patients is low. An abnormal pulse oximetry reading at presentation may help predict subsequent complications. Those patients with normal age-adjusted vital signs and physical exam at presentation may not require a prolonged observation period. PMID- 29452919 TI - High dose insulin for beta-blocker and calcium channel-blocker poisoning. AB - BACKGROUND/OBJECTIVES: High dose insulin (HDI) is a standard therapy for beta blocker (BB) and calcium channel-blocker (CCB) poisoning, however human case experience is rare. Our poison center routinely recommends HDI for shock from BBs or CCBs started at 1U/kg/h and titrated to 10U/kg/h. The study objective was to describe clinical characteristics and adverse events associated with HDI. METHODS: This was a structured chart review of patients receiving HDI for BB or CCB poisoning with HDI defined as insulin infusion of >=0.5U/kg/h. RESULTS: In total 199 patients met final inclusion criteria. Median age was 48years (range 14 89); 50% were male. Eighty-eight patients (44%) were poisoned by BBs, 66 (33%) by CCBs, and 45 (23%) by both. Median nadir pulse was 54 beats/min (range 12-121); median nadir systolic blood pressure was 70mmHg (range, 30-167). Forty-one patients (21%) experienced cardiac arrest; 31 (16%) died. Median insulin bolus was 1U/kg (range, 0.5-10). Median starting insulin infusion was 1U/kg/h (range 0.22-10); median peak infusion was 8U/kg/h (range 0.5-18). Hypokalemia occurred in 29% of patients. Hypoglycemia occurred in 31% of patients; 50% (29/50) experienced hypoglycemia when dextrose infusion concentration <=10%, and 30% (31/105) experienced hypoglycemia when dextrose infusion concentration >=20%. CONCLUSIONS: HDI, initiated by emergency physicians in consultation with a poison center, was feasible and safe in this large series. Metabolic abnormalities were common, highlighting the need for close monitoring. Hypoglycemia was more common when less concentrated dextrose maintenance infusions were utilized. PMID- 29452920 TI - Patient centered medical homes did not improve access to timely follow-up after ED visit. AB - BACKGROUND: Patients newly insured through coverage expansion under the Affordable Care Act (ACA) may have difficulty obtaining timely primary care follow-up appointments after emergency department (ED) discharge. We evaluated the association between availability of timely follow-up appointment with practice access improvements, including patient-centered medical home (PCMH) designations or extended-hours appointments. METHODS: We performed a secret shopper audit of primary care practices in greater New Haven, Connecticut. Two callers, posing as patients discharged from the ED, called these practices requesting follow-up appointments. They followed standardized scripts varying in ED diagnosis (uncontrolled hypertension, acute back pain) and insurance status (commercial, exchange, Medicaid). We linked our findings with data from a previously completed survey that assessed practice characteristics and examined the associations between appointment availability and practice access improvements. RESULTS: Of the 58 included primary care practices, 49 (84.5%) completed both the audit and the survey. Overall, 167/536 calls (31.2%) obtained an appointment in 7days. Practices with PCMH designation were less likely to offer appointments within 7days (23.4% vs. 33.1%, p=0.03). However, callers were more likely to obtain an appointment in 7days from practices offering after-hour appointments (36.3% vs. 27.8%, p=0.04). After adjusting for insurance type, there were no significant associations between practice improvements and 7-day appointment availability or appointment wait time. CONCLUSION: PCMH designation and extended-hours appointments were not associated with improved availability of timely primary care follow-up appointment for discharged ED patients. EDs should engage local clinicians and other stakeholders to strengthen linkage and care transition with outpatient practices.

PMID- 29452923 TI - Statistical and machine learning approaches to predicting protein-ligand interactions. AB - Data driven computational approaches to predicting protein-ligand binding are currently achieving unprecedented levels of accuracy on held-out test datasets. Up until now, however, this has not led to corresponding breakthroughs in our ability to design novel ligands for protein targets of interest. This review summarizes the current state of the art in this field, emphasizing the recent development of deep neural networks for predicting protein-ligand binding. We explain the major technical challenges that have caused difficulty with predicting novel ligands, including the problems of sampling noise and the challenge of using benchmark datasets that are sufficiently unbiased that they allow the model to extrapolate to new regimes. PMID- 29452922 TI - Structural biology of the separase-securin complex with crucial roles in chromosome segregation. AB - The cysteine protease separase opens the cohesin ring by cleaving its kleisin subunit and is a pivotal cell cycle factor for the transition from metaphase to anaphase. It is inhibited by forming a complex with the chaperone securin, and in vertebrates, also by the Cdk1-cyclin B1 complex. Separase is activated upon the destruction of securin or cyclin B1 by the proteasome, after ubiquitination by the anaphase-promoting complex/cyclosome (APC/C). Here we review recent structures of the active protease segment of Chaetomium thermophilum separase in complex with a substrate-mimic inhibitor and full-length Saccharomyces cerevisiae and Caenorhabditis elegans separase in complex with securin. These structures define the mechanism for substrate recognition and catalysis by separase, and show that securin has extensive contacts with separase, consistent with its chaperone function. They confirm that securin inhibits separase by binding as a pseudo substrate.

AB - OBJECTIVE: The objective of this study was to determine the rate of malignancy in incidentally detected T2 hyperintense hepatic lesions at breast MRI. METHODS: Incidental hepatic lesions identified during breast MRI, for which abdominal imaging was recommended, were retrospectively analyzed. RESULTS: Of the hepatic lesions, 97.3% were benign, and 2.7% were malignant, with a significant association between indication for the breast MRI and the malignancy status of the hepatic lesion (Fisher's Exact, P < 0.0142). CONCLUSION: Our initial experience suggests the benign nature of incidentally detected T2 hyperintense hepatic lesions at breast MRI in women without a newly diagnosed breast cancer.

AB - OBJECTIVE: Multi-sequence sagittal magnetic resonance imaging (MRI) of the entire spine is performed in patients with known single level spondylodiscitis. Our objective is to determine the frequency of multifocal infection. METHODS: After IRB approval, a retrospective five-year review of all patients with spondylodiscitis was performed. RESULTS: MRI identified 82 patients with single level infection. All 82 had entire spine imaging performed within 72 h of admission, showing additional non-continuous sites of infection in 19 patients (23%). Remote levels of spondylodiscitis were present in 11 patients (13%). CONCLUSION: Multi-sequence sagittal MRI of the entire spine may be helpful in patients with known single-level spine infection.

AB - Artificial design of metabolic pathways is essential for the production of useful compounds using microbes. Based on this design, heterogeneous genes are introduced into the host, and then various analysis and evaluation methods are conducted to ensure that the target enzyme reactions are functionalized within the cell. In this chapter, we list successful examples of useful compounds produced by designing artificial metabolic pathways, and describe the methods involved in analyzing, evaluating, and optimizing the target enzyme reaction. PMID- 29452927 TI - Toward prediction and control of antibiotic-resistance evolution. AB - The emergence of antibiotic-resistant bacteria is a serious public concern. To deal with this problem, recent advances in technology and the use of laboratory evolution experiments have provided valuable information on the phenotypic and genotypic changes that occur during the evolution of resistance. These studies have demonstrated the existence of evolutionary constraints on the development of drug-resistance, which suggests predictability in its evolution. In this review, we focus on the possibility to predict and control the evolution of antibiotic resistance, based on quantitative analysis of phenotypic and genotypic changes observed in bacterial laboratory evolution. We emphasize the key challenges in evolutionary biology that will contribute to the development of appropriate treatment strategies for preventing resistance evolution. PMID- 29452928 TI - Comprehensive on-line two-dimensional liquid chromatography * supercritical fluid chromatography with trapping column-assisted modulation for depolymerised lignin analysis. AB - Lignin depolymerisation produces a large variety of low molecular weight phenolic compounds that can be upgraded to value-added chemicals. Detailed analysis of these complex depolymerisation mixtures is, however, hampered by the lack of resolving power of traditional analysis techniques. In this study, a novel online comprehensive two-dimensional reversed-phase liquid chromatography (RPLC) * supercritical fluid chromatography (SFC) method with trapping column interface was developed for the separation of phenolic compounds in depolymerised lignin samples. The trapping capacities of different trapping columns were evaluated. The influence of large volume water-containing injection on SFC performance was studied. The relation between peak capacity and first dimension flow rate and gradient was investigated. The optimized method was applied for the analysis of a depolymerised lignin sample. The RPLC * SFC system exhibited high degree of orthogonality. Compared with traditional loop based interface, trapping column interface can significantly shorten the analysis time and offer higher detectability, with the disadvantage of more severe undersampling in the first dimension. PMID- 29452929 TI - The short-term effectiveness of low-level laser, phonophoresis, and iontophoresis in patients with lateral epicondylosis. AB - STUDY DESIGN: Randomized parallel group trial. INTRODUCTION: Various treatment options for lateral epicondylosis have been reported in the literature. PURPOSE OF STUDY: We aimed to compare the effectiveness of low-level laser therapy (LLLT), phonophoresis, and iontophoresis in terms of pain, function, and grip strength. METHODS: This study that comprised 37 patients with lateral epicondylosis was planned as a prospective randomized parallel group trial. Twelve participants were randomized to the LLLT group, 12 to the phonophoresis group, and 13 to the iontophoresis group. The Visual Analog Scale (VAS), pressure algometer, the Patient-Rated Tennis Elbow Evaluation, and grip strength dynamometer were used to measure outcomes. The measurements were performed at baseline and at the end of 15 sessions. RESULTS: Investigation of the pain scores revealed that all VAS scores were improved in both the laser and iontophoresis groups (VAS at rest: P = .015, effect size (ES) = 1.49 and P = .016, ES = 0.58, respectively; VAS during activity: P = .008, ES = 1.05 and P = .008, ES = 1.16, respectively; VAS at night: P = .013, ES = 1.01 and P = .016, ES = 0.72, respectively). Only advance in function and grip strength was associated with the iontophoresis group (Patient-Rated Tennis Elbow Evaluation P = .006, ES = 0.78; grip strength with elbow extension P = .011, ES = 1.03; with elbow flexion P = .003, ES = 0.52). DISCUSSION: The most effective approach could not be highlighted among the existing studies in the literature as they were applied in combination with other therapies. CONCLUSION: In our study, we observed that LLLT provides a benefit only for pain, whereas iontophoresis is beneficial for both pain and function. If the effect size is evaluated, LLLT is more influential than iontophoresis for decreasing pain. However, when we compared phonophoresis and iontophoresis in terms of effectiveness, we found that iontophoresis has better effects for pain, function, and grip strength. PMID- 29452930 TI - Mechanism-specific rehabilitation management of complex regional pain syndrome: Proposed recommendations from evidence synthesis. AB - STUDY DESIGN: Narrative review. INTRODUCTION: There are a variety of treatments with demonstrated effectiveness for the management of complex regional pain syndrome (CRPS). However given the variability in symptom presentation in this population, therapists may be unsure what treatments would be most effective for individual clients. PURPOSE OF THE STUDY: To present a brief synthesis of the literature and propose a rehabilitation version of a mechanism-specific management algorithm to guide personalized treatment of CRPS. METHODS: A systematic search of the literature was conducted to identify all randomized controlled trials, systematic reviews, and clinical practice guidelines addressing rehabilitation of CRPS. Results were reviewed independently by 2 reviewers and final selection of articles was reached by consensus, Data was extracted using standardized forms, and a single rater gave quality ratings. Both reviewers then used the extracted data to present a synthesis of the evidence categorized by the proposed mechanisms of effect. RESULTS: A total of 111 articles were retrieved and reviewed for inclusion; 49 were selected for data extraction. A synthesis of the key recommendations was compiled into a rehabilitation-specific version of the mechanism-based management algorithm proposed by Gierthmuhlen et al (2014). CONCLUSIONS: Consideration of mechanism appropriate rehabilitation interventions may assist therapists to select the most appropriate and effective treatments from the body of evidence supporting rehabilitation of CRPS. PMID- 29452931 TI - Identification of novel uncertainty factors and thresholds of toxicological concern for health hazard and risk assessment: Application to cleaning product ingredients. AB - Uncertainty factors (UFs) are commonly used during hazard and risk assessments to address uncertainties, including extrapolations among mammals and experimental durations. In risk assessment, default values are routinely used for interspecies extrapolation and interindividual variability. Whether default UFs are sufficient for various chemical uses or specific chemical classes remains understudied, particularly for ingredients in cleaning products. Therefore, we examined publicly available acute median lethal dose (LD50), and reproductive and developmental no-observed-adverse-effect level (NOAEL) and lowest-observed adverse-effect level (LOAEL) values for the rat model (oral). We employed probabilistic chemical toxicity distributions to identify likelihoods of encountering acute, subacute, subchronic and chronic toxicity thresholds for specific chemical categories and ingredients in cleaning products. We subsequently identified thresholds of toxicological concern (TTC) and then various UFs for: 1) acute (LD50s)-to-chronic (reproductive/developmental NOAELs) ratios (ACRs), 2) exposure duration extrapolations (e.g., subchronic-to-chronic; reproductive/developmental), and 3) LOAEL-to-NOAEL ratios considering subacute/acute developmental responses. These ratios (95% CIs) were calculated from pairwise threshold levels using Monte Carlo simulations to identify UFs for all ingredients in cleaning products. Based on data availability, chemical category-specific UFs were also identified for aliphatic acids and salts, aliphatic alcohols, inorganic acids and salts, and alkyl sulfates. In a number of cases, derived UFs were smaller than default values (e.g., 10) employed by regulatory agencies; however, larger UFs were occasionally identified. Such UFs could be used by assessors instead of relying on default values. These approaches for identifying mammalian TTCs and diverse UFs represent robust alternatives to application of default values for ingredients in cleaning products and other chemical classes. Findings can also support chemical substitutions during alternatives assessment, and data dossier development (e.g., read across), identification of TTCs, and screening-level hazard and risk assessment when toxicity data is unavailable for specific chemicals.

AB - Children in homes with intimate partner violence (IPV) are at increased risk for physical abuse. We determined the frequency and injury patterns in children who underwent child abuse consultation after IPV exposure by retrospectively analyzing the "Examination of Siblings To Recognize Abuse" cohort of children referred for physical abuse. Children were selected who presented after IPV exposure. Among 2890 children evaluated by child abuse pediatricians, 61 (2.1%) patients presented after IPV exposure. Of the 61, 11 (18.0%) were exposed to IPV, but had no direct involvement in the IPV event, 36 (59.0%) sustained inadvertent trauma during IPV, and 14 (23.0%) were directly assaulted during IPV. Thirty-six patients (59.0%) had an injury: 31 (51.0%) had cutaneous injuries and 15 (24.6%) had internal injuries including fracture(s), intracranial or intra-abdominal injury. Of the 15 patients with internal injuries, 14 (93.3%) were less than 12 months old. Among the 36 patients with injuries, 16 (44.4%) had no report of direct injury, a report of a mechanism that did not explain the identified injuries, or a report of trauma without a specific mechanism. Five (13.9%) did not have physical examination findings to suggest the extent of their internal injuries. Injuries are present in a significant proportion of children presenting to Emergency Departments after IPV exposure. History and physical examination alone are insufficient to detect internal injuries especially in infants. These preliminary results support the need for future, prospective studies of occult injury in children exposed to IPV. PMID- 29452934 TI - Evaluation of leader peptides that affect the secretory ability of a multiple bacteriocin transporter, EnkT. AB - EnkT is a novel ATP-binding cassette (ABC) transporter responsible for secretion of four bacteriocins, enterocins NKR-5-3A, C, D, and Z (Ent53A, C, D, and Z), produced by Enterococcus faecium NKR-5-3. It is generally recognized that the secretion of a bacteriocin requires a dedicated ABC transporter, although molecular mechanisms of this secretion are yet to be revealed. In order to characterize the unique ability of EnkT to secrete multiple bacteriocins, the role of N-terminal leader peptides of bacteriocin precursors was evaluated using Ent53C precursor as a model. The 18-amino acid leader peptide of Ent53C (Lc) was modified by site-directed mutagenesis to generate various point mutations, truncations, or extensions, and substitutions with other leader peptides. The impact of these Lc mutations on Ent53C secretion was evaluated using a quantitative antimicrobial activity assay. We observed that Ent53C production increased with Ala substitution of the highly conserved C-terminal double glycine residues that are recognized as the cleavage site. In contrast, Ent53C antimicrobial activity decreased, with decrease in the length of the putative alpha-helix-forming region of Lc. Furthermore, EnkT recognized and transported Ent53C of the transformants possessing heterologous leader peptides of enterocin A, pediocin PA-1, brochocins A and B, and lactococcins Qalpha and Qbeta. These results indicated that EnkT shows significant tolerance towards the sequence and length of leader peptides, to secrete multiple bacteriocins. This further demonstrates the functional diversity of bacteriocin ABC transporters and the importance of leader peptides as their recognition motif. PMID- 29452936 TI - Use of telemedicine in the management of infectious diseases. AB - Communication technologies have invaded our daily lives. Several studies have assessed these technologies in the management of infectious diseases (mainly HIV). Weekly short text messages and real-time compliance monitoring assessed in HIV patients are both associated with higher compliance in low-income countries. Virtual consultations to monitor stable chronic HIV patients or tuberculosis treatment in high-income countries appear to be acceptable and efficient. Although assessed in small studies, virtual monitoring seems to reinforce the doctor-patient relationship and the relation between primary care settings and hospitals in various infectious diseases (endocarditis, urinary tract infection, skin and soft tissue infection, HIV, tuberculosis, hepatitis C). A better prevention of infectious diseases (mainly sexually transmitted infections) seems to be observed with telemedicine tools. As fees for teleconsultation or telemonitoring have yet to be defined, the development and evaluation (cost effectiveness) of these tools are difficult. The regulatory framework will need to be improved to encourage such developments, all the while ensuring the confidentiality of data. The development of new tools will require the collaboration of physicians, users, and healthcare systems. PMID- 29452937 TI - Epigenetic chromatin modification by amber suppression technology. AB - The genetic incorporation of unnatural amino acids (UAAs) into proteins by amber suppression technology provides unique avenues to study protein structure, function and interactions both in vitro and in living cells and organisms. This approach has been particularly useful for studying mechanisms of epigenetic chromatin regulation, since these extensively involve dynamic changes in structure, complex formation and posttranslational modifications that are difficult to access by traditional approaches. Here, we review recent achievements in this field, emphasizing UAAs that help to unravel protein-protein interactions in cells by photo-crosslinking or that allow the biosynthesis of proteins with defined posttranslational modifications for studying their function and turnover in vitro and in cells. PMID- 29452935 TI - E3 Ligase VHL Promotes Group 2 Innate Lymphoid Cell Maturation and Function via Glycolysis Inhibition and Induction of Interleukin-33 Receptor. AB - Group 2 innate lymphoid cells (ILC2s) are a specialized subset of lymphoid effector cells that are critically involved in allergic responses; however, the mechanisms of their regulation remain unclear. We report that conditional deletion of the E3 ubiquitin ligase VHL in innate lymphoid progenitors minimally affected early-stage bone marrow ILC2s but caused a selective and intrinsic decrease in mature ILC2 numbers in peripheral non-lymphoid tissues, resulting in reduced type 2 immune responses. VHL deficiency caused the accumulation of hypoxia-inducible factor 1alpha (HIF1alpha) and attenuated interleukin-33 (IL-33) receptor ST2 expression, which was rectified by HIF1alpha ablation or inhibition. HIF1alpha-driven expression of the glycolytic enzyme pyruvate kinase M2 downmodulated ST2 expression via epigenetic modification and inhibited IL-33 induced ILC2 development. Our study indicates that the VHL-HIF-glycolysis axis is essential for the late-stage maturation and function of ILC2s via targeting IL-33 ST2 pathway.

AB - The introduction of site-specific DNA modifications to the genome or epigenome presents great opportunities for manipulating biological systems. Such changes are now possible through the combination of DNA-modifying enzymes with targeting modules, including dCas9, that can localize the enzymes to specific sites. In this review, we take a DNA modifying enzyme-centric view of recent advances. We highlight the variety of natural DNA-modifying enzymes-including DNA methyltransferases, oxygenases, deaminases, and glycosylases-that can be used for targeted editing and discuss how insights into the structure and function of these enzymes has further expanded editing potential by introducing enzyme variants with altered activities or by improving spatiotemporal control of modifications. PMID- 29452940 TI - Combining bedaquiline and delamanid to treat multidrug-resistant tuberculosis. PMID- 29452942 TI - Early safety and efficacy of the combination of bedaquiline and delamanid for the treatment of patients with drug-resistant tuberculosis in Armenia, India, and South Africa: a retrospective cohort study. AB - BACKGROUND: Bedaquiline and delamanid have been approved for treatment of multidrug-resistant (MDR) tuberculosis in the past 5 years. Because of theoretical safety concerns, patients have been unable to access the two drugs in combination. Medecins Sans Frontieres has supported the use of combination bedaquiline and delamanid for people with few treatment options since 2016. We describe early safety and efficacy of regimens containing the bedaquiline and delamanid combination in patients with drug-resistant tuberculosis in Yerevan, Armenia; Mumbai, India; and Khayelitsha, South Africa. METHODS: We retrospectively analysed a cohort of all patients who received 6-12 months of oral bedaquiline and delamanid in combination (400 mg bedaquiline once per day for 2 weeks, then 200 mg bedaquiline three times per week and 100 mg delamanid twice per day) in MSF-supported projects. We report serious adverse events, QTc corrected using the Fridericia formula (QTcF) interval data, and culture conversion data during the first 6 months of treatment. FINDINGS: Between Jan 1, 2016, and Aug 31, 2016, 28 patients (median age 32.5 years [IQR 28.5-40.5], 17 men) were included in the analysis. 11 (39%) of 28 patients were HIV-positive. 24 patients (86%) had isolates resistant to fluoroquinolones; 14 patients (50%) had extensively drug-resistant tuberculosis. No patient had an increase of more than 500 ms in their QTcF interval. Four patients (14%) had six instances of QTcF increase of more than 60 ms from baseline but none permanently discontinued the drugs. 16 serious adverse events were reported in seven patients. Of 23 individuals with positive baseline cultures, 17 (74%) converted to negative by month 6 of treatment. INTERPRETATION: Use of the bedaquiline and delamanid combination appears to reveal no additive or synergistic QTcF-prolonging effects. Access to bedaquiline and delamanid in combination should be expanded for people with few treatment options while awaiting the results of formal clinical trials.

Third-year midwifery students from Cumhuriyet University in the fall semesters of 2011 and 2012 were enrolled in the sponge and beef tongue model groups (n = 36 and n = 37, respectively). A checklist was prepared on the required skills for performing episiotomy which can be broken into three main parts, namely preparation, cutting and repairing and completion. According to the checklist, a Likert type questionnaire was developed including 5 items for preparation, 11 items for cutting and repairing, and 6 items for completion. After SBET with the sponge and beef tongue models in our laboratories of Midwifery Department, the students performed episiotomy steps in laboring women in Sivas State Hospital and then they filled in the questionnaire to indicate whether they gained self-confidence in performing episiotomy or not. Although, participants of both groups have successfully completed all the steps of episiotomy, overall, beef tongue model was found to be more successful regarding their self-confidence (p < 0.05), including the skills in performing local anesthesia; choosing needle holder, suture material and scissor for cutting; identifying apex, hymen and skin; using needle holder properly while penetrating into the skin, suturing vaginal mucosa until hymen, knotting, and suturing perineal muscles and skin. Our results suggest that while SBET with both models are applicable for episiotomy training of midwifery students in the laboratory setting, SBET with beef tongue model provides an additional increase in their self-confidence in the clinical settings.

AB - Inorganic mesoporous silica-based nanovehicles are highly promising for drug delivery but still suffer from the disadvantages of lacking functionality and poor biodegradability on account of the inert silica framework. Moreover, conventional cancer therapeutics typically employ toxic anticancer drugs or invasive external irradiations, which will inevitably give rise to severe adverse effects and diminished therapeutic outcome. In this work, we report on the iron engineered framework of mesoporous silica nanoparticles (MSNs) to fabricate a nanocatalyst with biodegradable and catalytic framework via a "dissolution regeneration" strategy (designated as rFeOx-HMSN). Based on the abundant overexpressed hydrogen peroxide (H2O2) and mild acidic nature in tumor microenvironment (TME), rFeOx-HMSN nanocatalyst could trigger in-situ Fenton-like reactions to produce highly toxic hydroxyl radicals (.OH), causing remarkable oxidative damages against tumor cells/xenografts. Additionally, the iron engineered rFeOx-HMSN nanocatalyst could readily collapse via an iron-extraction strategy under protein-rich environment, thereby improving the biodegradability of rFeOx-HMSN nanocatalyst. This work paves a promising way to engineer the inert framework of MSN into functional, biodegradable and catalytic nanoplatform, featuring effective tumor-therapeutic outcome and stimuli-responsive biodegradation concurrently. PMID- 29452945 TI - Reduction-sensitive fluorescence enhanced polymeric prodrug nanoparticles for combinational photothermal-chemotherapy. AB - In this study, a reduction-sensitive supramolecular polymeric drug delivery system was developed for combinational photothermal-chemotherapy of cancer. The multifunctional system was self-assembled by specific host-guest interactions between hydrophilic beta-cyclodextrin functionalized hyaluronic acid and adamantane linked camptothecin/dye conjugate, where a near-infrared (NIR) absorbing dye IR825 was loaded. The hydrophilic hyaluronic acid shell endows the assembly with excellent colloidal stability and biocompatibility. The embedded disulfide bond in the camptothecin/dye conjugate was cleaved under reducing environment, leading to the release of the conjugated drug and the recovery of fluorescence emission. Meanwhile, the dye IR825 could efficiently transfer the absorbed light into local heat, making the nanoplatform an effective system for photothermal therapy. As evident by confocal microscopy images, the nanoplatform was quickly internalized by HeLa, MCF-7, and U14 cancer cells and released drug molecules inside the cells. In vitro cell viability assays confirmed that the cancer cells were efficiently killed by the treatment of the nanoplatform under NIR light irradiation. Significant tumor regression was also observed in the tumor-bearing mice upon the administration of the nanoplatform through combinational photothermal-chemotherapy therapy. Hence, this nanoplatform presented a great potential in site-specific combined photothermal-chemotherapy of tumor. PMID- 29452946 TI - Time-responsive osteogenic niche of stem cells: A sequentially triggered, dual peptide loaded, alginate hybrid system for promoting cell activity and osteo differentiation. AB - The efficacy of stem cell-based bone tissue engineering has been hampered by cell death and limited fate control. A smart cell culture system with the capability of sequentially delivering multiple factors in specific growth stages, like the mechanism of the natural extracellular matrix modulating tissue formation, is attractive for enhancing cell activity and controlling cell fate. Here, a bone forming peptide-1 (BFP-1)-laden mesoporous silica nanoparticles (pep@MSNs) incorporated adhesion peptide, containing the arginine-glycine-aspartic acid (RGD) domain, modified alginate hydrogel (RA) system (pep@MSNs-RA) was developed to promote the activity and stimulate osteo-differentiation of human mesenchymal stem cells (hMSCs) in sequence. The survivability and proliferation of hMSCs were enhanced in the adhesion peptide modified hydrogel. Next, BFP-1 released from pep@MSNs induced hMSCs osteo-differentiation after the proliferation stage. Moreover, BFP-1 near the cells was self-captured by the additional cell-peptide cross-linked networks formed by the ligands (RGD) binding to receptors on the cell surface, leading to long-term sustained osteo-stimulation of hMSCs. The results suggest that independent and sequential stimulation in proliferation and osteo-differentiation stages could synergistically enhance the survivability, expansion, and osteogenesis of hMSCs, as compared to stimulating alone or simultaneously. Overall, this study provided a new and valid strategy for stem cell expansion and osteo-differentiation in 2D or 3D culture systems, possessing potential applications in 3D bio-printing and tissue regeneration. PMID- 29452947 TI - Highly stable molybdenum dioxide nanoparticles with strong plasmon resonance are promising in photothermal cancer therapy. AB - Photothermal therapy (PTT) is one of promising cancer therapy with high efficiency and minimal invasiveness. Exploiting of perfect PTT agent is vital to improve the therapy. In this study, a new type of bow tie-like molybdenum dioxide (MoO2) nanoparticles was successfully synthesized. These nanobow-ties had strong localized surface plasmon resonance (SPR) effect from visible to near infrared regions, and exhibited ultrahigh chemical stability. They could not only withstand high temperature heating without oxidation, but also resist the corrosion of strong acid and alkali. Meanwhile, the MoO2 nanoparticles were highly stable in protein-containing biological medium, though they partly degraded in PBS solution. Both in vivo and in vitro experiments indicated that they exhibited inappreciable toxicity. Under illumination of near infrared laser, they showed excellent PTT effect, as revealed by significant inhibition of cancer cell viability in vitro and efficient destruction in tumor tissue growth in vivo. These MoO2 nanoparticles possessed highly chemical stability and low toxicity with high PTT efficiency, thus promising them high potential as nanoagent in cancer treatment. PMID- 29452948 TI - Photo-tearable tape close-wrapped upconversion nanocapsules for near-infrared modulated efficient siRNA delivery and therapy. AB - RNA interference (RNAi) has become an appealing therapeutic approach for cancer and other diseases. One key challenge is the effective protection of these small fragile biomolecules against complicated physiological environments as well as efficient on-demand release. Here we design a photo-tearable polymer tape close wrapped nanocapsule for efficient NIR modulated siRNA delivery. The photo tearable nanocapsules comprise core-shell upconversion nanoparticles (UCNPs) coated with mesoporous silica layer for loading of photosensitizer hypocrellin A (HA) and small interfering RNA (siRNA) against polo-like kinase 1 (PLK1), and covalently bound thin membranes of polyethylene glycol (PEG) via a synthesized photocleavable linker (PhL). Upon irradiation at 980 nm, the UCNPs produce UV emissions to break PhL and tear out PEG membrane for siRNA release, and blue emissions to activate HA for generating reactive oxygen species (ROS). The close PEG membrane wrapping not only guarantees the efficient intracellular photocleavage, but also extends the circulation time and protects the loaded cargos from leakage and degradation. The ROS assists endosomal escape of the loaded cargos, therefore effectively improves the gene silencing efficiency and the suppressions of cell proliferation in vitro and tumor growth in vivo. The proposed photo-tearable tape-wrapped nanocapsules have promising potential application in precision medicine. PMID- 29452949 TI - Estimation of the effectiveness ratio (alpha/beta) for resistant cancer cells in U87MG human glioblastoma. AB - Glioblastoma contains self-renewing, tumorigenic cancer stem-like cells that contribute to tumor initiation and therapeutic resistance. The aim of this research was to estimate and compare the effectiveness ratio (alpha/beta) of stem like cells and differentiated glioma cells derived from the U87MG glioblastoma cell line. Cell survival experiments were obtained in a dose range of 0-20 Gy (13.52 +/- 0.09 Gy/h) as a hyperfractionationated accelerated radiotherapy scheme. Biochemical characterization of the post-irradiated cells was performed by flow cytometry analysis and the percentage of stem-like cells that resisted irradiation was determined by the CD133 expression. Results showed that U87MG stem-like cells are highly proliferative and more radioresistant than the U87MG adherent group (with a lesser stem-like character), this in association with the calculated alpha/beta ratio of 17 and 14.1, respectively. PMID- 29452951 TI - Antibacterial Weapons: Targeted Destruction in the Microbiota. AB - The intestinal microbiota plays an important role in health, particularly in promoting intestinal metabolic capacity and in maturing the immune system. The intestinal microbiota also mediates colonization resistance against pathogenic bacteria, hence protecting the host from infections. In addition, some bacterial pathogens deliver toxins that target phylogenetically related or distinct bacterial species in order to outcompete and establish within the microbiota. The most widely distributed weapons include bacteriocins, as well as contact dependent growth inhibition and type VI secretion systems. In this review, we discuss important advances about the impact of such antibacterial systems on shaping the intestinal microbiota. PMID- 29452950 TI - Dynamic Fungal Cell Wall Architecture in Stress Adaptation and Immune Evasion. AB - Deadly infections from opportunistic fungi have risen in frequency, largely because of the at-risk immunocompromised population created by advances in modern medicine and the HIV/AIDS pandemic. This review focuses on dynamics of the fungal polysaccharide cell wall, which plays an outsized role in fungal pathogenesis and therapy because it acts as both an environmental barrier and as the major interface with the host immune system. Human fungal pathogens use architectural strategies to mask epitopes from the host and prevent immune surveillance, and recent work elucidates how biotic and abiotic stresses present during infection can either block or enhance masking. The signaling components implicated in regulating fungal immune recognition can teach us how cell wall dynamics are controlled, and represent potential targets for interventions designed to boost or dampen immunity. PMID- 29452953 TI - The Archaellum: An Update on the Unique Archaeal Motility Structure. AB - Each of the three domains of life exhibits a unique motility structure: while Bacteria use flagella, Eukarya employ cilia, and Archaea swim using archaella. Since the new name for the archaeal motility structure was proposed, in 2012, a significant amount of new data on the regulation of transcription of archaella operons, the structure and function of archaellum subunits, their interactions, and cryo-EM data on in situ archaellum complexes in whole cells have been obtained. These data support the notion that the archaellum is evolutionary and structurally unrelated to the flagellum, but instead is related to archaeal and bacterial type IV pili and emphasize that it is a motility structure unique to the Archaea. PMID- 29452952 TI - Phasevarions of Bacterial Pathogens: Methylomics Sheds New Light on Old Enemies. AB - A wide variety of bacterial pathogens express phase-variable DNA methyltransferases that control expression of multiple genes via epigenetic mechanisms. These randomly switching regulons - phasevarions - regulate genes involved in pathogenesis, host adaptation, and antibiotic resistance. Individual phase-variable genes can be identified in silico as they contain easily recognized features such as simple sequence repeats (SSRs) or inverted repeats (IRs) that mediate the random switching of expression. Conversely, phasevarion controlled genes do not contain any easily identifiable features. The study of DNA methyltransferase specificity using Single-Molecule, Real-Time (SMRT) sequencing and methylome analysis has rapidly advanced the analysis of phasevarions by allowing methylomics to be combined with whole transcriptome/proteome analysis to comprehensively characterize these systems in a number of important bacterial pathogens.

PMID- 29452956 TI - Comparison of face-to-face interaction and the electronic medical record for venous thromboembolism risk stratification using the 2005 Caprini score. AB - OBJECTIVE: Perioperative venous thromboembolism (VTE) risk can be quantified with the 2005 Caprini score. The Caprini score has previously been validated by review of the electronic medical record (EMR) in >3000 plastic surgery patients. However, the accuracy of Caprini-based risk stratification using the EMR, as opposed to face-to-face contact with the patient, remains unknown. METHODS: Plastic and reconstructive surgery patients who had surgery under general anesthesia, required postoperative admission, and were started on enoxaparin prophylaxis were identified. The 2005 Caprini scores were calculated retrospectively using EMR review only (no direct contact with the patients) to establish cohort 1. The 2005 Caprini scores were calculated prospectively using face-to-face interaction with the patients, followed by EMR review, to establish cohort 2. For all included patients, EMR review or face-to-face screening was personally performed by the authors. We compared the proportions of patients with identified Caprini risk factors and the aggregate risk scores of patients between cohorts. RESULTS: Complete data were available for 536 unique patients in the EMR review cohort and 207 unique patients in the face-to-face cohort. Patients whose risk scores were calculated face to face had higher Caprini scores than those calculated by EMR review alone. The face-to-face cohort had a higher proportion of patients risk stratified as Caprini 7-8 (29.5% vs 24.8%) and Caprini >8 (26.6% vs 10.5%) compared with the EMR review cohort. Patients risk stratified by face to-face discussion were significantly more likely to be stratified into a higher risk Caprini stratum. Face-to-face discussion identified a 2-fold increase in patients with personal history of deep venous thrombosis (12.6% vs 6.3%; P = .005), a 3-fold increase in patients with family history of VTE (16.9% vs 5.2%; P < .001), and a 20-fold increase in patients with personal history of multiple lost pregnancies (13.6% vs 0.6%; P < .001) compared with EMR review. Observed differences for family history of VTE and history of pregnancy loss persisted after propensity score analysis, created using component variables in the 2005 Caprini score plus gender; this supports the conclusion that observed differences were not due to site variation or case mix. CONCLUSIONS: When it is used in isolation, the EMR may provide inaccurate estimation of patient-level VTE risk using the 2005 Caprini score. This study demonstrates that EMR review may miss key VTE risk factors, such as personal or family history of VTE, history of pregnancy loss, and others; this omission results in lower estimates of perioperative VTE risk. The importance of provider-patient interaction for accurate VTE risk stratification cannot be overstated. PMID- 29452957 TI - A systematic review of the efficacy and limitations of venous intervention in stasis ulceration. AB - BACKGROUND: Surgical techniques to address various components of chronic venous disease are rapidly evolving. Their efficacy and generally good results in treating superficial venous reflux (SVR) have been documented and compared in patients presenting with pain and swelling. A growing amount of literature is now available suggesting their efficacy in patients with venous leg ulcer (VLU). This review attempts to summarize the efficacy and limitations of commonly used venous interventions in the treatment of SVR and incompetent perforator veins (IPVs) in patients with VLU. METHODS: A systematic review of the published literature was performed. Two different searches were conducted in MEDLINE, Embase, and EBSCOhost to identify studies that examined the efficacy of SVR ablation and IPV ablation on healing rate and recurrence rate of VLU. RESULTS: In the whole review, 1940 articles were screened. Of those, 45 were included in the SVR ablation review and 4 in the IPV ablation review. Data were too heterogeneous to perform an adequate meta-analysis. The quality of evidence assessed by the Grading of Recommendations Assessment, Development, and Evaluation for the two outcomes varied from very low to moderate. Ulcer healing rate and recurrence rate were between 70% and 100% and 0% and 49% in the SVR ablation review and between 59% and 93% and 4% and 33% in the IPV ablation review, respectively. To explain those variable results, limitations such as inadequate diagnostic techniques, saphenous size, concomitant calf pump dysfunction, and associated deep venous reflux are discussed. CONCLUSIONS: Currently available minimally invasive techniques correct most venous pathologic processes in chronic venous disease with a good sustainable healing rate. There are still specific diagnostic and efficacy limitations that mandate proper match of individual patients with the planned approach. PMID- 29452958 TI - BRCA1 mutation spectrum, functions, and therapeutic strategies: The story so far. AB - BRCA1 gene mutations account for about 25-28% of hereditary Breast Cancer as BRCA1 is included in the category of high penetrance genes. Except for few commonmutations, there is a heterogenous spectrum of BRCA1 mutations in various ethnic groups. 185AGdel and 5382ins Care the most common BRCA1 alterations (founder mutations) which have been identified in most of the population. This review has been compiled with an aim to consolidate the information on genetic variants reported in BRCA1 found in various ethnic groups, their functional implications if known; involvement of BRCA1 in various cellular pathways/processes and potential BRCA1 targeted therapies. The pathological variations of BRCA1 vary among different ethical groups. A systematic search in PubMed and Google scholar for the literature on BRCA1 gene was carried out to figure out structure and function of BRCA1 gene. BRCA1 is a large protein having 1863 amino acids with multiple functional domains and interacts with multiple proteins to carry out various crucial cellular processes. BRCA1 plays a major role in maintaining genome integrity, transcription regulation, chromatin remodeling, cell cycle checkpoint control, DNA damage repair, chromosomal segregation, and apoptosis. Studies investigating the phenotypic response of mutant BRCA1 protein and comparing it to wildtype BRCA1 protein are clinically important as they are involved in homologous recombination and other repair mechanisms. These studies may help in developing more targetted therapies, detecting novel interacting partners, identification of new signaling pathways that BRCA1 is a part of or downstream target genes that BRCA1 affects. PMID- 29452959 TI - Differential expressions of MDM2 and TAP73 in cancer and cancer-adjacent tissues in patients with non-small-cell lung carcinoma. AB - AIM: To investigate the differences in mRNA and protein expressions of MDM2 (mouse double minute 2 homolog) and P73 in cancer and cancer-adjacent tissues in patients with non-small-cell lung carcinoma (NSCLC). MATERIALS AND METHODS: We compared the protein expressions of MDM2 and P73 in lung cancer and cancer adjacent tissues in NSCLC patients by IHC (immunohistochemistry) and WB (Western blot). We divided the NSCLC patients into two subgroups, adenocarcinoma and squamous carcinoma. The mRNA expressions of two main isoforms of P73, TAP73 and DNP73, as well as the ratio of DNP73/TAP73 were analyzed by qPCR (quantitative real-time PCR) in the two tissues in all NSCLC patients and in patients with adenocarcinoma or squamous carcinoma, respectively. RESULTS: WB results did not show significant differences in MDM2 and P73 protein expressions in lung cancer and cancer-adjacent tissues. However, IHC results indicated that MDM2 expression significantly increased in cancer tissues in female patients, but not male patients. In addition, TAP73 mRNA expression significantly increased in cancer tissues in all NSCLC patients (p=0.002) and in patients with adenocarcinoma (p=0.01); while there was no significant difference in DNP73 mRNA expression. Hence the fold-change of DNP73/TAP73 ratio significantly decreased (p=0.0003) in cancer tissues in all NSCLC patients and in patients with adenocarcinoma. CONCLUSIONS: TAP73 mRNA expression significantly increased in cancer tissues than cancer-adjacent tissues in all NSCLC patients and in patients with adenocarcinoma. Meanwhile, the fold-change of DNP73/TAP73 ratio was similar to TAP73. MDM2 protein expression significantly increased in cancer tissues in female NSCLC patients. PMID- 29452960 TI - Traditionally practiced medicinal plant extracts inhibit the ergosterol biosynthesis of clinically isolated dermatophytic pathogens. AB - OBJECTIVE: Dermatophytes are resistant to some available antibiotics. Development of new plant drugs to control drug resistant microbes is urgently needed. This study evaluates the antidermatophytic potential of 18 selected medicinal plants used by traditional healers in Theni and Virudhunagar Districts of Tamil Nadu, India. MATERIALS AND METHODS: Selected plant parts were collected, shade dried and powdered. Plant powders were extracted with ethanol and their antifungal potency was investigated against and clinical dermatophytes. The antioxidant effect of the extracts was screened using DPPH assay. Minimal Inhibitory Concentration (MIC) and Minimal Fungicidal Concentration (MFC) were estimated for the extracts. Ten plant extracts showed maximum MFC and they were selected to study their efficacy in interfering with ergosterol biosynthesis. Fluconazole 35MUg/mL known fungicide was used as control. The most active extracts were taken for biocompatibility studies using 3T3-L1 fibroblast cell lines. RESULTS: The ethanol extract of Phyllanthus reticulates leaves showed good antifungal activity compared to other plant extracts. The MIC and MFC for Phyllanthus reticulatus were 62.5 and 250MUg/mL against M. pachydermatitis and T. rubrum respectively. The ethanol extracts of Phyllanthus reticulatus, Coldenia procumbens, Thespesia populnea and Senna alata significantly lowered the release of ergosterol by 16.37, 19.53, 24.79, and 21.44%, respectively. The ethanol extract of Phyllanthus reticulatus leaves was more biocompatible to host cells than other active extracts. CONCLUSION: Our study indicated that the ethanol extract of Phyllanthus reticulates leaves showed promising activity against dermatophytes. It could be a potential material for future development of antidermatophytic agents. PMID- 29452962 TI - The role of resiliency and coping strategies in occurrence of positive changes in medical rescue workers. AB - BACKGROUND: Working in the emergency services entails exposure to traumatic events; however, their effects can be both negative and positive. Among the factors determining posttraumatic growth (PTG) after an experienced trauma are the personal resources and coping strategies. The purpose of the research was to investigate the role of resiliency and coping strategies with stress in posttraumatic growth in a group of medical rescue workers. MATERIALS AND METHODS: Data of 80 male medical rescuers who have experienced traumatic event in their worksite were analyzed. The Posttraumatic Growth Inventory, Resiliency Measurement Scale and Inventory to Measure Coping Strategies with Stress - Brief Cope were used in the study. Statistical tests such as t test, correlation and path analysis were used. RESULTS: The tested medical rescue workers revealed the medium level of PTG. Active coping, planning, turning to religion, seeking of social support, both emotional and instrumental, and self-distraction positively correlated with posttraumatic growth. A more significant role in the process of PTG appeared to be played by avoidance and emotional-focused strategies Although resiliency does not directly affect posttraumatic growth, it may strengthen it through the choice of coping strategies. CONCLUSIONS: In the process of posttraumatic growth avoidance strategies seem to play more important role than strategies focusing on the problem. PMID- 29452961 TI - Dipeptidyl peptidase-4 inhibitors (DPP-4i) combined with vitamin D3: An exploration to treat new-onset type 1 diabetes mellitus and latent autoimmune diabetes in adults in the future. AB - Type 1 diabetes mellitus (T1DM) is a chronic autoimmune disease characterized by destruction of pancreatic beta cells through cell injury caused primarily by cytotoxic T lymphocytes (CD8+). The pathophysiological basis of T1DM seems to be an imbalance between a reduced function of T regulatory lymphocytes and an increased inflammatory activity of Th17 lymphocytes caused by increased production of inflammatory cytokines, as IL-1beta, IL-6, IL-17 and IFN-gamma due to environmental factors and genetic predisposition. The preservation of the reserve of beta cells in new-onset T1DM and latent autoimmune diabetes in adults (LADA) by immunomodulation in addition to the incretin effect seems to be possible with an association of DPP-4 inhibitors and vitamin D3. In this review, we discuss the effects of both drugs on the immune system and on beta cell function and their eventual additive effects in preserving the residual function of beta cells in new-onset T1DM and LADA. PMID- 29452963 TI - Chemical sensing in development and function of intestinal lymphocytes. AB - The immune system of the intestinal tract has the challenging task of recognizing and eliminating intestinal pathogens while maintaining tolerance to dietary and commensal antigens; therefore, it must be able to sense environmental cues within the intestine and mount suitable responses dictated by their pathogenic or nonpathogenic nature. The aryl hydrocarbon receptor (AHR) was originally characterized as a chemical sensor of the environmental pollutant 2,3,7,8 tetrachlorodibenzo-p-dioxin (TCDD) [12]. More recently, AHR has emerged as a major chemical sensor expressed in many intestinal immune cells that enables them to distinguish nutritional and microbial cues and is, therefore, important for development, maintenance and function of the intestinal immune system. In this review, we will highlight recent advances in our knowledge of the role of AHR signaling in intestinal innate lymphoid cells (ILC), T cells and B cells. PMID- 29452964 TI - Risk factors for platelet transfusion in glioblastoma surgery. AB - The objectives of this study are to identify risk factors for and to evaluate clinical outcomes of platelet transfusion in glioblastoma surgery. The medical records of adult patients who underwent craniotomy for glioblastoma resection at a single academic medical center were retrospectively reviewed. We stratified patients into 2 groups: those who were transfused at least 1 unit of platelets intraoperatively or postoperatively (no more than 7 days after surgery), and those who were not transfused with platelets. Through the use of a 1:3 matched cohort analysis, we compared complications, length of stay, discharge disposition, and mortality, across groups. One hundred and five consecutive adult patients were included in this study. Thirteen patients (12.38%) received platelet transfusions. Prior antiplatelet therapy (odds ratio [OR] 8.21, 95% confidence interval [CI]: 2.36-28.58), preoperative platelet count less than 200,000 cells/uL (OR 8.46, 95% CI: 2.16-33.22), and longer operative times (OR 1.73, 95% CI: 1.10-2.72) were significant risk factors for platelet transfusion. There were no significant differences in the outcomes of interest in the matched cohort analysis. PMID- 29452966 TI - Gender differences in the relationship of childhood trauma and the course of illness in schizophrenia. AB - INTRODUCTION: Different types of childhood trauma have been repeatedly shown to contribute to psychotic symptoms. Gender differences in schizophrenia are well known. Some studies argue that trauma history means a significantly higher risk of psychosis for women than men. However, there is evidence of early adverse life events to be associated with higher stress-sensitivity in men. Little is known about the connection of specific type of trauma and specific psychotic symptoms as well as the course of illness with explicit regard to gender differences. METHODS: 102 men and women with schizophrenia spectrum disorder were tested using Structured Clinical Interview for DSM-IV-TR Axis I Disorders, Scale for Assessing Positive Symptoms, Early Trauma Inventory-SR. RESULTS: Although, women had a later age at onset without regarding trauma history (d = 0.74), this difference became non-significant when introducing trauma variables. Patients reporting physical abuse had a significantly earlier age at onset, regardless of their sex (V = 0.13, F = 3.11, p = 0.03. Physical abuse predicted an earlier age at onset only in women (R2 = 0.23). History of general trauma predicted more frequent hospitalizations only in men (R2 = 0.55). CONCLUSIONS: Although women generally tend to have a more favorable course of illness including a later age at onset men, women with CPA seem to lose this "advantage". It is necessary to investigate the contribution of gender interacting with adverse life events in contribution to the phenomenology and etiology of schizophrenia. PMID- 29452965 TI - Reversal of antiplatelet therapy in traumatic intracranial hemorrhage: Does timing matter? AB - Reversal of antiplatelet therapy with platelet transfusion in traumatic intracranial hemorrhage remains controversial. Several studies have examined this topic but few have investigated whether the timing of transfusion affects outcomes. Patients admitted to a level 1 trauma center from 1/1/14 to 3/31/16 with traumatic intracranial hemorrhage taking pre-injury antiplatelet therapy were retrospectively analyzed. Patients on concurrent pre-injury anticoagulant therapy were excluded. Per institutional guideline, patients on pre-injury clopidogrel received 2 doses of platelets while patients on pre-injury aspirin received 1 dose of platelets. Patients with worsening hemorrhage defined by an increase in the Rotterdam score on follow up CT were compared to those without worsening. Mortality, need for neurosurgical intervention, and timing of platelet transfusion were analyzed. A total of 243 patients were included with 23 (9.5%) having worsening hemorrhage. Patients with worsening hematoma had higher injury severity score, head abbreviated injury scale, incidence of subdural hematoma, mortality, and lower Glasgow coma scale. There was no significant difference in the number of minutes to platelet transfusion between groups. After logistic regression analysis the presence of subdural hematoma and lower admission Glasgow coma scale were predictors of worsening hematoma, while there remained no significant difference in minutes to platelet transfusion. The timing of platelet transfusion did not have any impact on rates of worsening hematoma for patients with traumatic intracranial hemorrhage on pre-injury antiplatelet therapy. Potential risk factors for worsening hematoma in this group are the presence of subdural hematoma and lower admission Glasgow coma scale.

AB - INTRODUCTION: In patients diagnosed with anal fistula, knowing the quality of life specifically related to the disease can help coloproctology specialists to choose the most appropriate therapeutic strategy for each case. The aim of our study is to analyzse and describe the factors related to the specific quality of life in a consecutive series of patients diagnosed with anal fistula. METHODS: Observational, cross-sectional study carried out from March 2015 to February 2017. All patients were assessed in the colorectal surgery unit of a hospital in southeast of Spain. After performing an initial anamnesis and a physical examination, patients diagnosed with anal fistula completed the Quality of Life in Ppatients with Anal Fistula Questionnaire (QoLAF-Q). This questionnaire specifically measures quality of life in people with anal fistula and its score range is the following: zero impact = 14 points, limited impact = 15 to 28 points, moderate impact = 29 to 42 points, high impact = 43 to 56 points, and very high impact = 57 to 70 points. RESULTS: A total of 80 patients were included. The median score obtained in the questionnaire for the sample studied was 34.00 (range=14-68). Statistically significant differences between patients with "primary anal fistula" (n=65) and "recurrent anal fistula" (n=15) were observed (mean rank=42.96 vs. mean rank=29.83, p=0.048). Furthermore, an inverse proportion (P=.016) between "time with clinical symptoms" and "impact on quality of life" was found (<6 months: mean rank = 45.55; 6-12 months: mean rank = 44.39; 1-2 years: mean rank = 37.83; 2-5 years: mean rank = 22; >5 years: mean rank = 19.00). There were no statistically significant differences (P=.149) between quality of life amongst patients diagnosed with complex (mean rank = 36.13) and simple fistulae (mean rank = 43.59). CONCLUSIONS: Anal fistulae exert moderate high impact on patients' quality of life. "Shorter time experiencing clinical symptoms" and the "presence of primary fistula" are factors that can be associated with worse quality of life.

AB - PURPOSE: Three tear supplements were compared for their effects on the signs, symptoms and inflammatory status of subjects with dry eye disease. Assessments were made before and after both 2 and 4 weeks of treatment. METHODS: In this masked, randomized, 3-way crossover trial, eighteen dry eye subjects were recruited. At each visit, symptoms, tear evaporation rate, stability and osmolarity were measured and tear samples were analyzed for 7 inflammatory markers, using multiplex immunoassays. The 3 treatments included carboxymethylcellulose-glycerine-castor oil (CGC), carboxymethylcellulose (CMC) and hydroxypropyl guar (HPG). The CGC and HPG drops are emulsified lipids; CGC also contains osmoprotectants. The CMC drop is a standard aqueous polymeric supplement. RESULTS: Significant improvements were seen in symptoms (OSDI) and tear stability (NITBUT) with all 3 treatments at 4 weeks. At 4 weeks post-CGC, 6 out of 7 biomarkers demonstrated a >25% reduction (in 40% of subjects). The same reduction (>25%) was seen in 10% of the subjects for CMC and in none of the subjects for HPG. No significantly different change to either evaporation rate or tear osmolarity was found following any of the three treatments. CONCLUSIONS: In this study, the CGC treatment resulted in the greatest reduction in ocular biomarkers of inflammation, while all 3 treatments reduced symptoms and improved tear stability. These results indicate that subject-perceived symptomatic improvements are not necessarily associated with a reduction in objective measures of inflammation.

AB - BACKGROUND: The aim of this prospective multicenter study is to investigate the association among (1) tibial site-specific overhang of medial, anterior, and lateral overhang in relation to Knee Injury and Osteoarthritis Outcome Score pain 1 year after surgery (1 Y KOOS pain) and (2) the malalignment of TKA components including overall malalignment in relation to 1 Y KOOS pain. METHODS: From 10 centers, across 4 continents, 323 patients were enrolled from October 2011 to February 2014. Radiographs were analyzed for tibial overhang on medial, anterior, and lateral site and for overall, tibial, femur, and combined malalignment. A 1 Y KOOS pain score <70 represented an unsatisfactory pain level. RESULTS: A significant association was observed between medial overhang and 1 Y KOOS pain with a cut-off of <70 (P = .04), with an odds ratio of 0.46. No significant associations were observed among the independent variables of lateral and anterior overhang or for overall, tibial, femoral, and combined component malalignment, and the dependent variable of 1 Y KOOS pain <70. CONCLUSION: This prospective multicenter study showed a significant association between medial overhang of the tibial component and a 1 Y KOOS pain <70. The related odds ratio was 0.46, which demonstrates that medial overhang may lead to a 54% reduced chance for entering an acceptable pain category 1 year after surgery when receiving a TKA. PMID- 29452972 TI - Does Preoperative Opioid Use Increase the Risk of Early Revision Total Hip Arthroplasty? AB - BACKGROUND: The purpose of this study is to evaluate the impact of preoperative opioid use on the risk of subsequent revison after primary total hip arthroplasty (THA). METHODS: The Humana database was queried for unilateral THA between 2007 2015. Patients were tracked for the occurrence of an ipsilateral revision THA for 2 years. Factors analyzed included preoperative opioid use (defined as a history of opioid prescription filled within 3 months preceding primary THA), age, sex, diabetes, anxiety/depression, chronic kidney disease, and obesity (body mass index > 30 kg/m2). Multivariate logistic regression analysis was used to determine odds ratios. RESULTS: A total of 17,695 primary THA patients were analyzed and 0.88% (n = 155) underwent revision THA within 2 years. Preoperative opioid use occurred in 36.7% of all. Females comprised 58.7% of the total cohort and 80% were >50 years. Preoperative opioid users were significantly more likely to undergo early THA revision (1.2% vs 0.7%, P < .001). Other patient factors that significantly increased the risk of early THA revision included obesity (1.3% vs 0.8%, P = .03) and a preoperative diagnosis of anxiety/depression (1.9% vs 0.8%, P = .006). CONCLUSION: Opioid use within 3 months preceding THA independently predicts an increased risk of early revision. Additionally, independent predictors of early revision include obesity and a diagnosis of anxiety/depression. Factors such as these will need to be considered in risk adjustment models when assessing quality of care or implementing bundled payment initiatives. Further research is needed to evaluate whether discontinuing opioids before surgery mitigates this risk. PMID- 29452973 TI - The Alpha-Defensin Test for Diagnosing Periprosthetic Joint Infection in the Setting of an Adverse Local Tissue Reaction Secondary to a Failed Metal-on-Metal Bearing or Corrosion at the Head-Neck Junction. AB - BACKGROUND: In patients with adverse local tissue reaction (ALTR) secondary to a failed metal-on-metal (MoM) bearing or corrosion at the head-neck junction in a metal-on-polyethylene bearing, ruling in or out periprosthetic joint infection (PJI) can be challenging. Alpha-defensin has emerged as an accurate test for PJI. The purpose of this multicenter, retrospective study was to evaluate the accuracy of the alpha-defensin synovial fluid test in detecting PJI in patients with ALTR. METHODS: We reviewed medical records of 26 patients from 3 centers with ALTR that had an alpha-defensin test performed. Patients were assessed for PJI using the Musculoskeletal Infection Society criteria. Thirteen of these subjects had MoM total hip arthroplasty, 9 had ALTR secondary to head-neck corrosion, and 4 had MoM hip resurfacing. RESULTS: Only 1 of the 26 patients met Musculoskeletal Infection Society criteria for infection. However, 9 hips were alpha-defensin positive, including 1 true positive and 8 that were falsely positive (31%). All 8 of the false positives were also Synovasure positive, although 5 of 8 had an accompanying warning stating the results may be falsely positive due to a low synovial C-reactive protein value. CONCLUSION: Similar to synovial fluid white blood cell count, alpha-defensin testing is prone to false-positive results in the setting of ALTR. Therefore, we recommend an aggressive approach to ruling out PJI including routine aspiration of all hips with ALTR before revision surgery to integrate the synovial fluid blood cell count, differential, cultures and adjunctive tests like alpha-defensin to allow for accurate diagnosis preoperatively. PMID- 29452974 TI - The Lawrence D. Dorr Surgical Techniques & Technologies Award: "Running Two Rooms" Does Not Compromise Outcomes or Patient Safety in Joint Arthroplasty. AB - BACKGROUND: Scrutiny from the federal government and the media regarding the safety of 1 surgeon doing cases in 2 operating rooms (ORs) on the same day, prompted us to examine our own institutional data. Over the past 11 years, surgeons at our facility have operated consecutively in 1 OR on a given day or used 2 alternating ORs. This study compares these cases with a focus on revisions and complications in both groups. METHODS: Six surgeons performed a total of 16,916 primary hip and knee arthroplasties from 2006-2016. 7002 cases (41%) were consecutive cases (CCs) and 9914 cases (59%) were overlapping cases (OCs). Intraoperative complications, component revisions, and postoperative complications within 90 days of surgery were compared between the CC and OC groups. RESULTS: There was no difference in intraoperative complication rates between the two groups (CC 1.6% vs. OC 1.7%, relative risk 1.082, 95% confidence interval 0.852 to 1.375, P = .52). There was no difference in 90-day component revision rates among the CC and OC groups (0.66% vs. 0.85% respectively, relative risk = 1.290, 95% confidence interval 0.901 to 1.845, P = .19). There was also no difference in 90-day complication rates among the CC and OC groups (1.33% vs. 1.45% respectively, relative risk = 1.094, 95% confidence interval 0.844 to 1.417, P = .54). CONCLUSION: This large study of a single institution with multiple surgeons over an 11-year period shows no compromise in patient safety or outcomes when comparing cases done in either consecutive or overlapping rooms.

PMID- 29452975 TI - Associations between Food Security Status and Dietary Inflammatory Potential within Lower-Income Adults from the United States National Health and Nutrition Examination Survey, Cycles 2007 to 2014. AB - BACKGROUND: Evidence suggests both that chronic inflammation mediates the association of food insecurity with adverse health outcomes and that diet may be a significant source of inflammation among food insecure individuals. OBJECTIVE: To examine whether food security status is associated with dietary inflammatory potential. DESIGN AND PARTICIPANTS: Cross-sectional data came from the National Health and Nutrition Examination Survey (NHANES), cycles 2007 to 2014 (n=10,630). The analysis sample is representative of noninstitutionalized US adults with an income-to-poverty ratio <=3.00. MAIN OUTCOME: Dietary Inflammatory Index (DII) score, calculated using the average of two 24-hour dietary recalls, was the main outcome measure. STATISTICAL ANALYSIS: Type III F tests or chi2 tests compared population characteristics by food security status, defined using the US Food Security Survey Module. Multivariable linear regression was used to estimate the association between food security status and the DII score and moderation by demographic factors. Survey weighting procedures accounted for the effects of stratification and clustering used in the NHANES study design. RESULTS: When accounting for socioeconomic status, demographic factors, and health status, DII score was higher at greater levels of food insecurity (P=0.0033). Those with very low food security had a 0.31 (95% CI=0.12 to 0.49) higher DII score than those with high food security. Age moderated the association between food security status and DII score (interaction P=0.0103), where the magnitude of the association between DII score and severity of food insecurity was higher for those >65 years than for younger age groups. CONCLUSION: Food security status may be associated with dietary inflammatory potential, which is hypothesized to play a role in multiple chronic health conditions. Further research is needed to determine the causal nature of this relationship and evaluate how best to implement programs designed to address health disparities within food insecure populations. PMID- 29452977 TI - Arguments Used in Public Comments to Support or Oppose the US Department of Agriculture's Minimum Stocking Requirements: A Content Analysis. AB - BACKGROUND: In 2016, the US Department of Agriculture (USDA)'s Supplemental Nutrition Assistance Program (SNAP) Retailer Rule proposed several changes for SNAP-authorized retailers, including: requiring retailers to have at least 85% of their food sales come from items that are not cooked or heated on site before or after purchase; requiring stores to stock seven varieties of qualifying foods from four staple food groups; requiring stores to carry perishable foods in three of the four staple groups; requiring stores to carry six units of qualifying foods at all times (depth of stock); disqualifying multiple ingredient foods and accessory foods from counting toward depth of stock requirements. OBJECTIVES: To better understand arguments used to support or oppose the USDA's proposed rule that all SNAP-authorized retailers carry more nutritious foods. DESIGN: We conducted a qualitative content analysis of a random sample of public comments posted to the US Federal Register (a publicly available database) in response to the USDA's proposed rule. PARTICIPANTS/SETTING: A random sample of 20% of all public comments submitted by individuals and organizations to the US Federal Register were analyzed (n=303) for this study. RESULTS: Three main themes were discussed: 1) arguments used in opposition to the rule; 2) arguments used in support of the rule; and 3) facilitators to assist stores in implementing the rule. Some of the subthemes included focusing on definitions used in the rule, reduced food access caused by stores leaving the SNAP program, lack of space and equipment for healthy foods, and the potential for increasing healthy food access. CONCLUSIONS: Nutrition and dietetics practitioners may be tasked with working with stores to implement healthy changes. Nutrition and dietetics practitioners must understand the role that the USDA has in food policy. In addition, understanding how federal food policy influences the environments in which dietetics professionals' clients are making food choices is important. PMID- 29452978 TI - The management of antibodies in heart transplantation: An ISHLT consensus document. AB - Despite the successes from refined peri-operative management techniques and immunosuppressive therapies, antibodies remain a serious cause of morbidity and mortality for patients both before and after heart transplantation. Patients awaiting transplant who possess antibodies against human leukocyte antigen are disadvantaged by having to wait longer to receive an organ from a suitably matched donor. The number of pre-sensitized patients has been increasing, a trend that is likely due to the increased use of mechanical circulatory support devices. Even patients who are not pre-sensitized can go on to produce donor specific antibodies after transplant, which are associated with worse outcomes. The difficulty in managing antibodies is uncertainty over which antibodies are of clinical relevance, which patients to treat, and which treatments are most effective and safe. There is a distinct lack of data from prospective trials. An international consensus conference was organized and attended by 103 participants from 75 centers to debate contentious issues, determine the best practices, and formulate ideas for future research on antibodies. Prominent experts presented state-of-the-art talks on antibodies, which were followed by group discussions, and then, finally, a reconvened session to establish consensus where possible. Herein we address the discussion, consensus points, and research ideas. PMID- 29452979 TI - 3-Piece Inflatable Penile Prosthesis Placement Following Radical Cystoprostatectomy and Urinary Diversion: Technique and Outcomes. AB - BACKGROUND: After radical cystoprostatectomy (RC), postoperative erectile dysfunction (ED) is a common consequence with multiple contributing etiologies. The inflatable penile prosthesis (IPP) offers patients a definitive treatment option when ED is refractory to medical therapies. Because of the hostile postoperative anatomy of these patients, a careful surgical approach is necessary for successful outcomes and to avoid adjacent organ injury. To date, there is no series describing the outcomes of 3-piece IPP placement in patients with urinary diversions. AIM: To present contemporary outcomes and a description of our technique in placing a 3-piece IPP for postoperative ED in patients with a history of RC with orthotopic neobladder, ileal conduit, or continent cutaneous diversion. METHODS: We retrospectively reviewed 80 patients who underwent primary placement of a 3-piece IPP (AMS 700; American Medical Systems Inc, Minnetonka, MN, USA) after RC and urinary diversion from 2003 through 2016. 79 patients underwent RC in their treatment of urologic malignancy (71 for bladder cancer, 8 for prostate cancer) and 1 underwent RC for refractory interstitial cystitis. An infrapubic approach was used in most patients, with reservoir placement in the lateral retroperitoneal space through a counterincision medial to the anterior superior iliac spine. Patient demographics, perioperative data, and postoperative outcomes including prosthetic infection and mechanical failure were examined and statistical analysis was performed. OUTCOMES: Rates of device infection, revision surgery, and reservoir complications. RESULTS: After mean follow-up of 53.9 months (6.5-150.7 months), 4 patients developed infection of the prosthesis that required explantation. 3 of those patients underwent successful IPP reimplantation. 5 patients required revision surgery (pump replacement, n = 3; pump relocation, n = 1; cylinder replacement for cylinder aneurysm, n = 1) for mechanical failure. No statistically significant associations were found between infection and comorbidities, urinary diversion, exposure to chemotherapy, radiation, or presence of an artificial urinary sphincter. CLINICAL IMPLICATIONS: The 3-piece IPP is an effective treatment option for medication-refractory ED that can be placed safely in patients with all forms of urinary diversion. STRENGTHS AND LIMITATIONS: This study represents the 1st series that describes a successful technique and long-term outcomes of patients with urinary diversion. It is limited by its single-surgeon, single-center experience and lacks validated patient satisfaction data in follow-up. CONCLUSIONS: The 3-piece IPP, with reservoir placement in the lateral retroperitoneum, can be implanted successfully in patients with all forms of urinary diversion without a significant increase in infectious complications, reservoir erosion, or mechanical failure.

PMID- 29452980 TI - Association between smoking cessation and weight gain in treatment-seeking African Americans. AB - INTRODUCTION: Research has shown that African Americans gain more than average weight after smoking cessation. However, African Americans have been underrepresented in post-cessation weight gain research. The current study examined 1) the pattern of weight gain and 2) the association between smoking status and weight gain in a sample of African Americans seeking smoking cessation treatment. METHODS: Data were drawn from a randomized controlled trial testing the efficacy of a 4-week culturally specific smoking cessation cognitive behavioral therapy (CBT) intervention among African American smokers (N = 342). Weight was measured and self-reported smoking status was biochemically verified at baseline, end of counseling, 3-, 6-, and 12-month follow-ups. Random effects multilevel modeling was used to examine weight gain over twelve months post CBT, and a fully unconditional model tested the pattern of weight gain over time. Smoking status was included as a time-varying factor to examine its effect on weight gain, controlling for potential confounding variables. RESULTS: Weight significantly increased among those who remained abstinent over 12 months post CBT [average gain of seven lbs. (three kg)]. Controlling for covariates, abstinence was predictive of the rate of weight gain for those with high weight concern. CONCLUSIONS: Weight gain among African American abstainers was comparable to the average post-cessation weight gain observed among the general population. It is possible that exposure to CBT (culturally specific or standard) may have mitigated excessive weight gain. Future research should assess predictors of weight gain in African American smokers to inform future smoking cessation interventions and help elucidate factors that contribute to tobacco- and obesity-related health disparities. PMID- 29452981 TI - Body mass index and tobacco-product use among U.S. youth: Findings from wave 1 (2013-2014) of the Population Assessment of Tobacco and Health (PATH) Study. AB - INTRODUCTION: Tobacco and obesity are leading contributors to mortality in the United States. Due to emerging changes in youth tobacco use, further examination of co-occurrence of these issues is warranted. METHODS: This study examined associations between body mass index (BMI) and tobacco-product use and whether these varied by gender in a nationally representative sample of 12,416 Wave 1 (2013-2014) U.S. youth (12-17 years) from the Population Assessment of Tobacco and Health Study. Multivariable logistic regression analyses examined the odds of past 30-day tobacco-product use according to BMI. BMI was analyzed categorically using the Centers for Disease Control and Prevention (CDC) BMI-for-age weight status categories (underweight/healthy weight, overweight, and obese) and as a continuous variable. RESULTS: Youth classified as overweight or obese were not more likely to use any tobacco, cigarettes, e-cigarettes, any cigar, or hookah. However, youth who were obese were more likely to use smokeless tobacco (Adjusted Odds Ratio (AOR) = 1.68, 95% Confidence Interval (CI): 1.01, 2.81). There were no significant gender interactions for these associations. When BMI was analyzed continuously, a 5-unit and 10-unit increase was significantly associated with using any tobacco, cigarettes, any cigar, and smokeless tobacco. This linear association was supported by similar results for a log-transformed BMI variable. CONCLUSIONS: Findings suggest a continuum between weight increase and tobacco product use among American youth. Clinicians should consider screening for tobacco use among youth who gain weight within any weight class, not just those considered overweight or obese. PMID- 29452982 TI - Reactive Oxygen Species: Involvement in T Cell Signaling and Metabolism. AB - T cells are a central component of defenses against pathogens and tumors. Their effector functions are sustained by specific metabolic changes that occur upon activation, and these have been the focus of renewed interest. Energy production inevitably generates unwanted products, namely reactive oxygen species (ROS), which have long been known to trigger cell death. However, there is now evidence that ROS also act as intracellular signaling molecules both in steady-state and upon antigen recognition. The levels and localization of ROS contribute to the redox modeling of effector proteins and transcription factors, influencing the outcome of the T cell response. We discuss here how ROS can directly fine-tune metabolism and effector functions of T cells. PMID- 29452983 TI - Orchestration of NLRP3 Inflammasome Activation by Ion Fluxes. AB - The assembly of the NLRP3 inflammasome can promote the release of IL-1beta/IL-18 and initiate pyroptosis. Accordingly, the dysregulation of NLRP3 inflammasome activation is involved in a variety of human diseases, including gout, diabetes, and Alzheimer's disease. NLRP3 can sense a variety of structurally unrelated pathogen-associated molecular patterns (PAMPs) or danger-associated molecular patterns (DAMPs) to trigger inflammation, but the unifying mechanism of NLRP3 activation is still poorly understood. Increasing evidence suggests that intracellular ions, such as K+, Ca2+, and Cl-, have a significant role in NLRP3 inflammasome activation. Here, we review the current knowledge about the role of ionic fluxes in NLRP3 inflammasome activation and discuss how disturbances in intracellular ionic levels orchestrate different signaling events upstream of NLRP3. PMID- 29452984 TI - Quantitative cerebrovascular pathology in a community-based cohort of older adults. AB - Cerebrovascular disease, especially small vessel pathology, is the leading comorbidity in degenerative disorders. We applied arterial spin labeling and cerebrovascular reserve (CVR) imaging to quantify small vessel disease and study its effect on cognitive symptoms in nondemented older adults from a community based cohort. We evaluated baseline cerebral blood flow (CBF) using arterial spin labeling and percent signal change as a marker of CVR using blood-oxygen level dependent imaging following a breath-hold stimulus. Measurements were performed in and near white matter hyperintensities, which are currently the standard to assess severity of vascular pathology. We show that similar to other studies (1) CBF and CVR are markedly reduced in the hyperintensities as well as in the tissue surrounding them, indicating susceptibility to infarction; (2) low CBF and CVR are significantly correlated with poor cognitive performance; and (3) in addition, compared to a 58.4% reduction in CBF, larger exhaustion (79.3%) of CVR was observed in the hyperintensities with a faster, nonlinear rate of decline. We conclude that CVR may be a more sensitive biomarker of small vessel disease than CBF. PMID- 29452985 TI - Effectiveness of two home ergonomic programs in reducing pain and enhancing quality of life in informal caregivers of post-stroke patients: A pilot randomized controlled clinical trial. AB - BACKGROUND: Informal caregivers of post-stroke patients usually undergo high levels of pain and stress and have a reduced quality of life. OBJECTIVE: To evaluate the effectiveness of two home ergonomic interventions aimed at reducing pain intensity and perceived stress and enhancing the quality of life in informal caregivers of chronic post-stroke patients. METHODS: A randomized single-blind controlled clinical trial was conducted, with a sample of 33 informal caregivers of patients with stroke. Three groups were included: one received postural hygiene training and kinesiotherapy, for 12 weeks, two days a week, one hour per session; another received adaptation of the home environment, and the third was a control group. Pain intensity, stress level and general quality of life were evaluated at three-time points: pre-intervention, post-intervention, and after a follow-up period of three months. RESULTS: Neck pain decreased in the two experimental groups, and increased in the control group. Pain in the shoulders and knees was alleviated in the group that received postural hygiene and kinesiotherapy. In addition, regarding quality of life, this group obtained an improvement in the physical health dimension, while the home adaptation group reported improved social relationships. CONCLUSIONS: These results suggest that 12 weeks of training in postural hygiene, combined with kinesiotherapy, and home adaptations can reduce pain and improve several aspects of the quality of life of this population. CLINICALTRIALS. GOV ID: NCT03284580. PMID- 29452986 TI - The psychological consequences of violence against people with disabilities. AB - BACKGROUND: People with disabilities experience mental health disparities and higher rates of violence compared to people without disabilities. Few studies have examined the psychological consequences of violence against people with disabilities, and whether they differ from those experienced by people without disabilities. OBJECTIVE: This study compared psychological consequences of violence among men and women with and without disabilities. METHODS: We analyzed data from the 2008-2014 waves of the National Crime Victimization Survey. Multiple logistic regressions were estimated to compare the psychological impact of violent crime on respondents without disabilities to those with disabilities, who comprised roughly 20% of the sample (n = 8,070). We stratified by gender to compare the effects of violence experienced by men and women. RESULTS: Men with disabilities were more likely than men without disabilities to report severe distress (AOR = 2.07, p < 0.001), anxiety (1.79, p < 0.001), depression (2.32, p < 0.001), and anxiety and depression (2.34; p < 0.001), but were less likely to experience each outcome compared to women with disabilities. Men with disabilities had similar odds of adverse psychological outcomes compared to women without disabilities. Women with disabilities had higher odds of severe distress following violence compared to men without disabilities (3.90, p < 0.001) or women without disabilities (1.86, p < 0.001). Similarly, women with disabilities had higher odds of anxiety, depression, and anxiety and depression compared to men and women without disabilities. CONCLUSIONS: Women with disabilities are at higher risk of negative psychological consequences resulting from violence compared to other gender-disability groups. Men with disabilities also experience worse outcomes relative to men without disabilities. PMID- 29452987 TI - Cell therapy for peripheral artery disease. AB - Patients with severe peripheral artery disease (PAD) who are not candidates for revascularization have poor prognosis. Cell therapy using peripheral blood derived or bone marrow-derived mononuclear cells, mesenchymal stem cells, or marker-specific subsets of bone marrow cells with angiogenic properties may hold promise for no-option PAD patients. Injected cells may exert beneficial actions by enhancing local angiogenesis (either through maturation of endothelial progenitors, or through secretion of angiogenic mediators), or by transducing cytoprotective signals that preserve tissue structure. Despite extensive research, robust clinical evidence supporting the use of cell therapy in patients with critical limb ischemia is lacking. Larger, well-designed placebo-controlled clinical trials did not support the positive results of smaller less rigorous studies. There is a need for high-quality clinical studies to test the effectiveness of cell therapy in PAD patients. Moreover, fundamental cell biological studies are needed to identify the optimal cell types, and to develop strategies that may enhance homing, survival and effectiveness of the injected cells. PMID- 29452988 TI - Expert consensus recommendations on the cardiogenetic care for patients with thoracic aortic disease and their first-degree relatives. AB - BACKGROUND: Thoracic aortic aneurysm (TAA) is a potentially life-threatening disorder with a strong genetic component. The number of genes implicated in TAA has increased exponentially over the last decade. Approximately 20% of patients with TAA have a positive family history. As most TAA remain asymptomatic for a long time, screening of at risk relatives is warranted to prevent complications. Existing international guidelines lack detailed instructions regarding genetic evaluation and family screening of TAA patients. We aimed to develop a consensus document to provide medical guidance for all health care professionals involved in the recognition, diagnosis and treatment of patients with thoracic aortic disease and their relatives. METHODS: A multidisciplinary panel of experts including cardiologists, cardiothoracic surgeons, clinical geneticists and general practitioners, convened to review and discuss the current literature, guidelines and clinical practice on genetic testing and family screening in TAA. RESULTS: There is a lack of high-quality evidence in the literature. This consensus statement, based on the available literature and expert opinions, summarizes our recommendations in order to standardize and optimize the cardiogenetic care for patients and families with thoracic aortic disease. In particular, we provide criteria to identify those patients most likely to have a genetic predisposition, and discuss the preferred modality and frequency of screening in their relatives. CONCLUSIONS: Age, family history, aortic size and syndromic features determine who is advised to have genetic testing as well as screening of first-degree relatives. There is a need for more prospective multicenter studies to optimize current recommendations. PMID- 29452989 TI - Prognostic role of cardiac calcifications in primary prevention: A powerful marker of adverse outcome highly dependent on underlying cardiac rhythm. AB - BACKGROUND: Increasing evidence exists regarding calcium detected in aortic cusps and/or mitral annulus (AOC_MAC) at transthoracic echocardiogram as a predictor of cardiovascular (CV) events and mortality. PURPOSE: To verify whether AOC_MAC has a prognostic role in the setting of primary prevention independently of the presence of atrial fibrillation (AF). METHODS: All subjects consecutively referred from January 2011 to October 2014 to the Cardiovascular Centre for CV risk assessment in primary prevention were selected. AOC_MAC was assessed by transthoracic echocardiography. Primary study endpoint was a composite of CV hospitalizations/all-cause death. RESULTS: The 1389 study patients were 70 years old, 43% males, 24% had diabetes mellitus, 75% arterial hypertension, 56% dyslipidaemia. Of all, 997 (72%) were in sinus rhythm (SR), 392 (28%) in AF. Patients with AF were older and more frequently males, with larger atria than SR subjects. During a median follow-up of 32 months, 165 patients (12%) were hospitalized for CV cause, 68 (5%) died. The primary endpoint occurred more frequently in patients with than without AOC_MAC (18% vs 11%, p < 0.001). AF patients showed higher event-rate compared with patients in SR (20% vs 10%, respectively; p < 0.01). AOC_MAC emerged as an independent prognosticator of primary endpoint in SR patients (HR 1.74 [1.07-2.82], p = 0.02), together with increasing age and left ventricular hypertrophy, while AOC_MAC had no prognostic relevance in AF patients. CONCLUSIONS: In subjects with multiple CV risk factors assessed in primary prevention, the presence of AF nullifies the prognostic power of AOC_MAC, on the contrary robustly confirmed in SR patients.

AB - Antibiotic therapy is essential in foreign body associated infections. The treatment regime should aim at high tissue concentrations, high bioavailability, high biofilm penetration and good tolerance. We investigated whether the new cephalosporin ceftobiprole is active against clinical isolates from musculoskeletal foreign body associated infections. One hundred ninety-six staphylococci isolates (coagulase negative staphylococci and Staphylococcus aureus) derived from foreign body associated infections were tested towards susceptibility to ceftobiprole, using a test strip assay and broth microdilution. The MIC for all strains S. aureus indicated susceptibility to ceftobiprole. The MIC of only two strains of coagulase negative staphylococci was above 2 mg/L. Our results show that ceftobiprole might be considered as an off-label treatment option in foreign body associated infections. PMID- 29452993 TI - An in vitro evaluation of the efficacy of tedizolid: implications for the treatment of skin and soft tissue infections. AB - Skin and soft tissue infections (SSTI) are among the most commonly occurring infections and evidence suggests that these are increasing world-wide. The aetiology is diverse, but Staphylococcus aureus predominate and these are often resistant to antimicrobials that were previously effective. Tedizolid is a new oxazolidinone-class antibacterial indicated for the treatment of adults with SSTI caused by Gram-positive pathogens, including S. aureus. The aim of this study was to evaluate the in vitro efficacy of tedizolid in comparison to other clinically used antibacterials against antibiotic sensitive- and resistant-staphylococci, grown in planktonic cultures and as biofilms reflecting the growth of the microorganism during episodes of SSTI. Against a panel of 66 clinical staphylococci, sensitivity testing revealed that a lower concentration of tedizolid was required to inhibit the growth of staphylococci compared to linezolid, vancomycin and daptomycin; with the tedizolid MIC50 being 8-fold (S. aureus) or 4-fold (S. epidermidis) below that obtained for linezolid. In addition, cfr+ linezolid-resistant strains remained fully susceptible to tedizolid. Against S. aureus biofilms, 10*MIC tedizolid was superior or comparable with 10*MIC comparator agents in activity, and superior to 10*MIC linezolid against those formed by S. epidermidis (65 vs. 33% reduction, respectively). Under flow-conditions both oxazolidinones at 10*MIC statistically out-performed vancomycin in their ability to reduce the viable cell count within a S. aureus biofilm with fewer the 12% of cells surviving compared to 63% of cells. In conclusion, tedizolid offers a realistic lower-dose alternative agent to treat staphylococcal SSTI, including infections caused by multi-drug resistant strains. PMID- 29452994 TI - Transmission routes of respiratory viruses among humans. AB - Respiratory tract infections can be caused by a wide variety of viruses. Airborne transmission via droplets and aerosols enables some of these viruses to spread efficiently among humans, causing outbreaks that are difficult to control. Many outbreaks have been investigated retrospectively to study the possible routes of inter-human virus transmission. The results of these studies are often inconclusive and at the same time data from controlled experiments is sparse. Therefore, fundamental knowledge on transmission routes that could be used to improve intervention strategies is still missing. We here present an overview of the available data from experimental and observational studies on the transmission routes of respiratory viruses between humans, identify knowledge gaps, and discuss how the available knowledge is currently implemented in isolation guidelines in health care settings. PMID- 29452941 TI - Surgical site infection after gastrointestinal surgery in high-income, middle income, and low-income countries: a prospective, international, multicentre cohort study. AB - BACKGROUND: Surgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world. METHODS: This international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the GlobalSurg 1 study and other studies that have been found to affect the likelihood of SSI were entered into risk adjustment models. The primary outcome measure was the 30-day SSI incidence (defined by US Centers for Disease Control and Prevention criteria for superficial and deep incisional SSI). Relationships with explanatory variables were examined using Bayesian multilevel logistic regression models. This trial is registered with ClinicalTrials.gov, number NCT02662231. FINDINGS: Between Jan 4, 2016, and July 31, 2016, 13 265 records were submitted for analysis. 12 539 patients from 343 hospitals in 66 countries were included. 7339 (58.5%) patient were from high-HDI countries (193 hospitals in 30 countries), 3918 (31.2%) patients were from middle-HDI countries (82 hospitals in 18 countries), and 1282 (10.2%) patients were from low-HDI countries (68 hospitals in 18 countries). In total, 1538 (12.3%) patients had SSI within 30 days of surgery. The incidence of SSI varied between countries with high (691 [9.4%] of 7339 patients), middle (549 [14.0%] of 3918 patients), and low (298 [23.2%] of 1282) HDI (p<0.001). The highest SSI incidence in each HDI group was after dirty surgery (102 [17.8%] of 574 patients in high-HDI countries; 74 [31.4%] of 236 patients in middle-HDI countries; 72 [39.8%] of 181 patients in low-HDI countries). Following risk factor adjustment, patients in low-HDI countries were at greatest risk of SSI (adjusted odds ratio 1.60, 95% credible interval 1.05 2.37; p=0.030). 132 (21.6%) of 610 patients with an SSI and a microbiology culture result had an infection that was resistant to the prophylactic antibiotic used. Resistant infections were detected in 49 (16.6%) of 295 patients in high HDI countries, in 37 (19.8%) of 187 patients in middle-HDI countries, and in 46 (35.9%) of 128 patients in low-HDI countries (p<0.001). INTERPRETATION: Countries with a low HDI carry a disproportionately greater burden of SSI than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of WHO recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication.

PMID- 29452996 TI - Nomogram for Predicting the Risk of Invasive Pulmonary Adenocarcinoma for Pure Ground-Glass Nodules. AB - BACKGROUND: The pure ground-glass nodule is a common clinical concern. The purpose of this study was to develop a nomogram to predict the risk of invasive pulmonary adenocarcinoma in patients with pure ground-glass nodules 1 cm or less in diameter based on the computed tomography imaging features. METHODS: We reviewed a total of 250 patients who had undergone resection of pure ground-glass nodules 1 cm or less in diameter in our hospital, including the data of histopathologic examinations after surgical resection. Clinical information and imaging features were analyzed by the use of univariable and multivariable logistic regression analysis. A nomogram to predict the risk of invasive pulmonary adenocarcinoma was developed, and the calibration curves for the probability were drawn. RESULTS: Two hundred fifty patients were enrolled for analysis: 13 as having benign lesions, 8 as atypical adenomatous hyperplasia, 64 as adenocarcinoma in situ, 137 as minimally invasive adenocarcinoma, and 28 as invasive adenocarcinoma. On the basis of the final regression analysis, the lesion size, spiculation, lobulation, air bronchogram, vascular convergence, pleural tag, and the computed tomography window width were identified and were entered into the nomogram. The nomogram showed an excellent discrimination, with an area under the receiver operating characteristics curve of 0.916 for internal validation and 0.970 for external validation. The calibration curves for the probability of invasive pulmonary adenocarcinoma showed optimal agreement between the predicted probability by the nomogram and the actual probability. CONCLUSIONS: We constructed a novel nomogram that can predict the risk of invasive pulmonary adenocarcinoma for patients with pure ground-glass nodules 1 cm or less in diameter. With highly accurate, excellent calibration and discrimination of the model, clinicians could more precisely make a specific treatment strategy for each patient. PMID- 29452995 TI - Immune barriers of Ebola virus infection. AB - Since its initial emergence in 1976 in northern Democratic Republic of Congo (DRC), Ebola virus (EBOV) has been a global health concern due to its virulence in humans, the mystery surrounding the identity of its host reservoir and the unpredictable nature of Ebola virus disease (EVD) outbreaks. Early after the first clinical descriptions of a disease resembling a 'septic-shock-like syndrome', with coagulation abnormalities and multi-system organ failure, researchers began to evaluate the role of the host immune response in EVD pathophysiology. In this review, we summarize how data gathered during the last 40 years in the laboratory as well as in the field have provided insight into EBOV immunity. From molecular mechanisms involved in EBOV recognition in infected cells, to antigen processing and adaptive immune responses, we discuss current knowledge on the main immune barriers of infection as well as outstanding research questions. PMID- 29452997 TI - Long-Term Outcomes of Total Anomalous Pulmonary Venous Drainage Repair in Neonates and Infants. AB - BACKGROUND: Outcomes of operations for total anomalous pulmonary venous drainage (TAPVD) have improved. However, operations in the neonatal period and the development of postoperative pulmonary venous obstruction are associated with a high mortality rate. METHODS: A retrospective review was conducted for all neonates and infants (n = 214) who underwent operations for isolated TAPVD (1973 to 2014). RESULTS: Median age was 18 days (1 day to 1 year). There were 17 (7.9%) early deaths. Risk factors for early death were prolonged cardiopulmonary bypass time (p = 0.005) and neonatal age at the operation (p = 0.048). Early mortality was 2.5% for infants (n = 81) and 11% for neonates (n = 133; p = 0.021) during the entire study period. Hospital deaths for neonates remained unchanged during the four eras of 1973 to 1988, 1989 to 1998, 1999 to 2008, and 2009 to 2014. Survival at 10 and 20 years was 88% +/- 2.2% (95% confidence interval, 82% to 91%). Reoperation for postoperative pulmonary venous obstruction was required in 22 patients (10%). Risk factors for reoperation were prolonged cardiopulmonary bypass time (p = 0.015), lower operative weight (p = 0.003), and an episode of postoperative pulmonary hypertensive crisis (p = 0.005). Freedom from reoperation at 20 years was 86% +/- 3.2% (95% confidence interval, 78% to 91%). All survivors were asymptomatic at a mean of 13 +/- 9 years (range, 1 month to 42 years) after the operation. CONCLUSIONS: Although isolated TAPVD repair in infants can be performed without death, the operation is associated with a high mortality rate in neonates that remained unchanged during the long study period. Survival beyond 1 year after the operation is associated with excellent long-term outcomes. PMID- 29452999 TI - Chylothorax as a Risk Factor for Thrombosis in Adults: A Proof-of-Concept Study. AB - BACKGROUND: Postoperative chylothorax in children is associated with an increased risk of vascular thrombosis, hypothesized to be from loss of antithrombin into chylous fluid resulting in a hypercoagulable state. In adults, an increased thrombotic risk with chylothorax has not been described. Adults undergoing Ivor Lewis esophagogastrectomy have two strong thrombotic risk factors-active malignancy and postoperative state-allowing for relative homogeneity in baseline thrombotic risk; therefore, we studied the association of chylothorax with thrombosis in this population. METHODS: We performed a single-center retrospective cohort study at a tertiary care academic center. Patients included adults undergoing Ivor-Lewis esophagogastrectomy between January 1, 2006, and December 31, 2012. We collected demographics, pleural fluid characteristics, and relevant imaging within 30 days after the operation. Using nominal logistic regression, we studied the effects of chylothorax, age, sex, body mass index, American Society of Anesthesiologists Physical Status Classification, operative duration, and hospital length of stay on the incidence of postoperative thrombosis. RESULTS: We identified 608 patients who underwent Ivor-Lewis esophagogastrectomy. Of these, 524 (86.2%) had no pleural fluid analysis, 48 (7.9%) had nonchylous effusions, and 36 (5.9%) had chylothoraces, with incident acute vascular thrombosis within 30 days postoperatively occurring in 22 of 524 (4.2%), 2 of 48 (4.2%), and 8 of 36 (22.2%), respectively (p = 0.001). In multivariate analyses, after adjusting for the above factors, chylothorax was associated with significantly higher odds of any vascular thrombosis (odds ratio, 5.46; p = 0.0013) and deep venous thrombosis/pulmonary embolism (odds ratio, 6.76; p = 0.0016). CONCLUSIONS: Chylothorax is associated with a significantly higher incidence of vascular thrombosis in adults undergoing Ivor-Lewis esophagogastrectomy. Vascular thrombosis was associated with a significantly higher 90-day mortality rate. PMID- 29452998 TI - Resection of Intrathoracic Paraganglioma With and Without Cardiopulmonary Bypass. AB - BACKGROUND: Intrathoracic paragangliomas (PGLs) are rare tumors. Approximately 50% originate from and around cardiac structures. METHODS: A retrospective review was made of the perioperative course of patients with intrathoracic PGL resection from 2000 through 2015 at Mayo Clinic in Rochester, Minnesota. RESULTS: Twenty two patients underwent PGL resection. Sixteen patients (73%) had functioning tumors (11, noradrenergic; 4, mixed noradrenergic and dopaminergic; 1, dopaminergic). Patients with functioning tumors received preoperative adrenergic blockade: 15 (68%), alpha1,2-adrenergic receptor antagonist; 4 (18%), alpha1 adrenergic receptor antagonists; and 13 (59%) metyrosine. Six patients with nonfunctioning tumors had no adrenergic blockade. Twelve patients had tumor resection without cardiopulmonary bypass-9 for PGL associated with the great vessels, 2 for PGL with pericardial involvement, and 1 for PGL in right atrioventricular groove. Ten patients required cardiopulmonary bypass; for 9, the tumor involved cardiac structures and for 1, it involved ascending aorta and proximal aortic arch. Of these, 1 patient had uncontrollable bleeding and died intraoperatively. Other than this single death, there were no inhospital major cardiac or pulmonary complications. Median follow-up was 8.2 years (range, 2.1 to 17.2). Six patients subsequently had metastatic disease, and of them, 1 died 6 years after the operation. CONCLUSIONS: In this series, 73% of intrathoracic PGLs were functional and involved noradrenergic, mixed noradrenergic and dopaminergic, or pure dopaminergic secretion. Cardiac and pericardial paraganglioma resection may require cardiopulmonary bypass. Although intraoperative bleeding in most complex cases may be uncontrollable, as for 1 of our patients, those who survived hospital discharge had favorable long-term outcomes. PMID- 29453000 TI - Neoadjuvant Chemoradiation Shows No Survival Advantage to Chemotherapy Alone in Stage IIIA Patients. AB - BACKGROUND: For operable patients with clinical stage IIIA non-small cell lung cancer, the optimum neoadjuvant treatment strategy remains unclear. Our aim was to compare perioperative and long-term outcomes for patients receiving neoadjuvant chemoradiotherapy (NCRT) versus neoadjuvant chemotherapy (NCT) alone. METHODS: We queried the National Cancer Database to identify all patients with N2 and either T1-T2 non-small cell lung cancer who received either NCRT or NCT followed by lobectomy between 2006 and 2012. Patients with T3 tumors were excluded. A propensity match analysis was performed incorporating preoperative variables, and the incidence of postoperative complications, pathologic downstaging, and long-term survival were compared. RESULTS: In all, 1,936 patients met criteria, 745 NCT and 1,191 NCRT. The NCRT patients were younger, less likely to be treated at an academic medical center, and more likely to have adenocarcinoma. After propensity matching, patients in the NCT group showed lower 30-day mortality (1.3% versus 2.9%) and 90-day mortality (2.9% versus 6.0%), and were more likely to undergo a minimally invasive resection (25.7% versus 14.1%). The NCRT patients were more likely to have a pathologic complete response (14.2% versus 4.0%) and to be N0 at the time of resection (45.2% versus 38.7%). In the multivariable analysis, NCRT patients were at a greater risk of mortality than NCT patients (hazard ratio 1.18, 95% confidence interval: 1.03 to 1.36). CONCLUSIONS: In our cohort, combined neoadjuvant chemotherapy and radiation therapy was associated with improved pathologic downstaging but showed increased perioperative mortality with no improvement in long-term overall survival. For stage IIIA patients with smaller tumors without local invasion, chemotherapy alone may be the preferred neoadjuvant treatment. PMID- 29453001 TI - Transmitral Septal Myectomy for Hypertrophic Obstructive Cardiomyopathy. AB - BACKGROUND: Intrinsic abnormalities of the mitral valve are common in patients with hypertrophic cardiomyopathy and may need to be addressed at operation. METHODS: Consecutive patients undergoing transmitral septal myectomy were retrospectively reviewed. The ventricular septum was exposed through a left atriotomy, and the anterior leaflet of the mitral valve was detached from its annulus. An extended myectomy was performed to the base of the papillary muscles. After myectomy, the anterior leaflet was reattached and concomitant mitral valve repair or replacement was performed. In some cases, we performed a modified anterolateral commissural closure suture, which served to reposition the lateral aspect of the anterior leaflet out of the left ventricular outflow tract ("curtain stitch"). RESULTS: Twenty patients who underwent this procedure were identified (70% women; mean age 63 years). Mitral regurgitation was moderate in 55% and severe in 40%. Preoperative peak left ventricular outflow tract gradient was 92 +/- 43 mm Hg. Mitral valve repair (n = 11) or replacement (n = 9) was performed. Predischarge transthoracic echocardiography demonstrated a left ventricular outflow tract gradient of 10 +/- 5 mm Hg. There was no operative mortality. Follow-up was 100% complete and averaged 22 +/- 25 months. No patient required reoperation, and there was no recurrence of left ventricular outflow tract obstruction or mitral regurgitation greater than mild. CONCLUSIONS: Potential advantages of transmitral myectomy include a panoramic view of the septum and mitral subvalvular apparatus and the ability to simultaneously address mitral valve pathology. Consideration should be given to using the transmitral approach to septal myectomy as the preferred approach for the surgical treatment of hypertrophic cardiomyopathy. PMID- 29453002 TI - Operative Outcomes of Multiple-Arterial Versus Single-Arterial Coronary Bypass Grafting. AB - BACKGROUND: More than 90% of coronary artery bypass grafting (CABG) is performed with a single-arterial bypass graft (SABG), based on the left internal thoracic artery (ITA) with supplemental vein grafts. This practice, often justified by safety concerns with multiple-arterial grafting (MABG), defies evidence of improved late survival achieved with bilateral ITA (BITA-MABG) or left ITA plus radial artery (RA-MABG). We hypothesized that MABG and SABG are equally safe. METHODS: We analyzed The Society of Thoracic Surgeons National Database (2004 to 2015) to assess the operative safety of BITA-MABG (n = 73,054) and RA-MABG (n = 97,623) vs SABG (n = 1,334,511). Primary end points were operative (30-day or same hospitalization) mortality (OM) and deep sternal wound infections (DSWI). Risk-adjusted odds ratios (AOR) and 95% confidence intervals (CIs) were derived from by logistic regression with sensitivity analyses in multiple subcohorts including MABG use rate. RESULTS: SABG (73.8% men; median age, 66 years), BITA MABG (85.1% men; median age, 59 years), and RA-MABG (82.5% men; median age, 61 years) showed distinctly different patient characteristics. Compared with SABG (1.91% OM; 0.73% DSWI), observed OM was lower for BITA-MABG (1.19%, p < 0.001) and RA-MABG (1.19%, p < 0.001). DSWI was higher among BITA-MABG (1.08%, p < 0.001) and similar for RA-MABG (0.71%, p = 0.55). BITA-MABG showed marginally increased, likely not clinically significant, OM (AOR, 1.14; 95% CI, 1.00 to 1.30; p = 0.05) and doubled DSWI (AOR, 2.09; 95% CI, 1.80 to 2.43; p < 0.001). RA MABG had similar OM (AOR, 1.01; 95% CI, 0.89 to 1.15; p = 0.85) and DSWI (AOR, 0.97; 95% CI, 0.83 to 1.13; p = 0.70). Results were consistent across multiple subcohorts. A U-shaped OM vs BITA use relation was documented, with worse OM at hospitals with low (<5%: AOR, 1.38; 95% CI, 1.18 to 1.61; p < 0.001) and high (>=40%: AOR, 1.31; 95% CI, 1.00 to 1.70; p = 0.049) BITA use. CONCLUSIONS: MABG in the United States is associated with OM comparable to SABG and increased DSWI risk with BITA-MABG. Our findings highlight the importance of surgeon and institutional experience and careful patient selection for BITA-MABG. Our short term results should not in any way dissuade the use of MABG, given its well established long-term survival advantage. PMID- 29453003 TI - Effects of AUT00063, a Kv3.1 channel modulator, on noise-induced hyperactivity in the dorsal cochlear nucleus. AB - The purpose of this study was to test whether a Kv3 potassium channel modulator, AUT00063, has therapeutic potential for reversing noise-induced increases in spontaneous neural activity, a state that is widely believed to underlie noise induced tinnitus. Recordings were conducted in noise exposed and control hamsters from dorsal cochlear nucleus (DCN) fusiform cells before and following intraperitoneal administration of AUT00063 (30 mg/kg). Fusiform cell spontaneous activity was increased in sound-exposed animals, approximating levels that were nearly 50% above those of controls. Administration of AUT00063 resulted in a powerful suppression of this hyperactivity. The first signs of this suppression began 13 min after AUT00063 administration, but activity continued to decline gradually until reaching a floor level which was approximately 60% of pre-drug baseline by 25 min after drug treatment. A similar suppressive effect of AUT00063 was observed in control animals, with onset of suppression first apparent at 13 min post-treatment, but continuing to decline toward a floor level that was 54% of pre-drug baseline and was reached 28 min after drug treatment. In contrast, no suppression of spontaneous activity was observed in animals given similar injections of vehicle (control) solution. The suppressive effect of AUT00063 was achieved without significantly altering heart rate and with minimal effects on response thresholds, supporting the interpretation that the reductions of hyperactivity were not a secondary consequence of a more general physiological suppression of the brain or auditory system. These findings suggest that Kv3 channel modulation may be an effective approach to suppressing spontaneous activity in the auditory system and may provide a future avenue for treatment of tinnitus resulting from exposure to intense sound. PMID- 29453004 TI - Electrochemical surface-enhanced Raman scattering measurement on ligand capped PbS quantum dots at gap of Au nanodimer. AB - The vibrational characteristics of ligand-capped lead sulfide (PbS) quantum dots (QDs) were clarified via electrochemical surface-enhanced Raman spectroscopy (EC SERS) using a hybridized system of gold (Au) nanodimers and PbS QDs under electrochemical potential control. Enhanced electromagnetic field caused by the coupling of QDs with plasmonic Au nanodimers allowed the characteristic behavior of the ligand oleic acid (OA) on the PbS QD surface to be detected under electrochemical potential control. Binding modes between the QDs and OA molecules were characterized using synchronous two-dimensional correlation spectra at distinct electrochemical potentials, confirming that the bidentate bridging mode was probably the most stable mode even under relatively negative potential polarization. Changes in binding modes and molecular orientations resulted in fluctuations in EC-SERS spectra. The present observations strongly recommend the validity of the QD-plasmonic nanostructure coupled system for sensitive molecular detection via EC-SERS. PMID- 29453005 TI - Post-mortem quetiapine concentrations in hair segments of psychiatric patients - Correlation between hair concentration, dose and concentration in blood. AB - Drug analysis in hair is useful when seeking to establish drug intake over a period of months to years. Segmental hair analysis can also document whether psychiatric patients are receiving a stable intake of antipsychotics. This study describes segmental analysis of the antipsychotic drug quetiapine in post-mortem hair samples from long-term quetiapine users by ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) analysis. The aim was to obtain more knowledge on quetiapine concentrations in hair and to relate the concentration in hair to the administered dose and the post-mortem concentration in femoral blood. We analyzed hair samples from 22 deceased quetiapine-treated individuals, who were divided into two groups: natural hair colour and dyed/bleached hair. Two to six 1cm long segments were analyzed per individual, depending on the length of the hair, with 6cm corresponding to the last six months before death. The average daily quetiapine dose and average concentration in hair for the last six months prior to death were examined for potential correlation. Estimated doses ranged from 45 to 1040mg quetiapine daily over the period, and the average concentration in hair ranged from 0.18 to 13ng/mg. A significant positive correlation was observed between estimated daily dosage of quetiapine and average concentration in hair for individuals with natural hair colour (p=0.00005), but statistical significance was not reached for individuals with dyed/bleached hair (p=0.31). The individual coefficient of variation (CV) of the quetiapine concentrations between segments ranged from 3 to 34% for individuals with natural hair colour and 22-62% for individuals with dyed/bleached hair. Dose-adjusted concentrations in hair were significantly lower in females with dyed/bleached hair than in individuals with natural hair colour. The quetiapine concentrations in post-mortem femoral blood and in the proximal hair segment, segment 1 (S1), representing the last month before death were also investigated for correlation. A significant positive correlation was observed between quetiapine concentrations in blood at the time of death and concentrations in S1 for individuals with natural hair colour (p=0.003) but not for individuals with dyed/bleached hair (p=0.31). The blood concentrations of quetiapine ranged from 0.006 to 1.9mg/kg, and the quetiapine concentrations in S1 ranged from 0.22 to 24ng/mg. The results of this study suggest a positive correlation of quetiapine between both concentrations in hair and doses, and between proximal hair (S1) and blood concentrations, when conditions such as hair treatments are taken into consideration. PMID- 29453006 TI - Illicit and prescription drug misuse as reported to the Maine Diversion Alert Program. AB - BACKGROUND: The opioid epidemic is rapidly evolving and new tools are needed to combat drug abuse. The Maine Diversion Alert Program (DAP) is an informational resource that facilitates communication about drug arrests between the criminal justice and healthcare fields. The objectives of this report were to: (1) describe the illegal and prescription pharmaceuticals reported to the DAP; (2) determine if the drugs implicated in arrests changed from the first to latter half of 2016; (3) identify the demographic and other characteristics of arrestees; and (4) outline the strengths and limitations of the DAP for other areas considering implementing similar programs. METHODS: The arrests (N=2,368, 31.4% female, mean age=33.7, SD=9.9, Min=18, Max=71.5) reported to the DAP were examined. Drugs were classified by Drug Enforcement Administration Schedule (I-V, non-controlled prescription) and into families (opioids, stimulants, sedatives, hallucinogens, and other). A comparison between the first and second half of 2016 and arrest by county was completed. RESULTS: Arrests involved 2,957 substances (drugs and paraphernalia). Most arrests (80.6%) involved a single drug. One-third (33.2%) of arrests involved illicit drugs (i.e. Schedule I) and three-fifths (59.8%) were for controlled prescription medical drugs (i.e. Schedule II-V), and a minority (6.8%) involved non-controlled prescription drugs (e.g. gabapentin, bupropion). Opioids (e.g. heroin, buprenorphine, and oxycodone) accounted for over-half (51.3%) of arrests followed by stimulants (29.0%, e.g. cocaine), and sedatives (7.6%). Arrests for oxycodone significantly decreased (51.9%) and alprazolam increased (89.3%) during 2016. Arrestees for non-controlled prescription drugs were older than arrestees for illegal drugs. Arrests, correcting for population, were most common in more urban (e.g. Androscoggin and Cumberland) counties. CONCLUSIONS: Opioids (illicit and prescription) account for over half of all arrests. However, arrests for oxycodone decreased while arrests for benzodiazepines, and especially alprazolam, increased in 2016. The DAP is a novel source of information for healthcare decisions and can empirically inform law enforcement about drug misuse and addiction. PMID- 29453007 TI - When is myocarditis indeed the cause of death? AB - Attribution of death to myocarditis continues to be a controversial issue in forensic pathology, despite the existence of established histopathological criteria as well as complementary investigations. The aim of the study was two fold: (a) to retrospectively analyse the data obtained from a series of clinical and forensic autopsies in order to assess the number of cases with death attributed to myocarditis, and (b) to reevaluate these cases in order to assess how properly the histopathological diagnosis of myocarditis conformed to established criteria and therefore how accurately these were used on the basis of all postmortem investigation findings to conclude the cause of death. 2474 clinical and forensic autopsies were taken into consideration. Myocarditis was recorded as the official, underlying cause of death in 48 cases. Of those, 8 cases were considered to accurately conform to the histopathological Dallas criteria for the presence of myocarditis and could therefore be classified as cases of fatal myocarditis. In 19 out of 48 cases, description of focal myocarditis was considered to accurately fulfill the histopathological Dallas criteria for the presence of myocarditis. However, data provided by histological analysis and virology testing result reevaluation allowed alternative causes of death to be speculated. In another 21 out of 48 cases, description of focal myocardial inflammation was considered to inaccurately meet the histopathological Dallas criteria for the presence of myocarditis. The findings of our own study appear to be in agreement with previous observations in similar study groups and highlight that since myocarditis may occur in association with many diseases, a great deal of evidence is required before settling on categorical conclusions. PMID- 29453008 TI - Forensic image analysis - CCTV distortion and artefacts. AB - As a result of the worldwide deployment of surveillance cameras, authorities have gained a powerful tool that captures footage of activities of people in public areas. Surveillance cameras allow continuous monitoring of the area and allow footage to be obtained for later use, if a criminal or other act of interest occurs. Following this, a forensic practitioner, or expert witness can be required to analyse the footage of the Person of Interest. The examination ultimately aims at evaluating the strength of evidence at source and activity levels. In this paper, both source and activity levels are inferred from the trace, obtained in the form of CCTV footage. The source level alludes to features observed within the anatomy and gait of an individual, whilst the activity level relates to activity undertaken by the individual within the footage. The strength of evidence depends on the value of the information recorded, where the activity level is robust, yet source level requires further development. It is therefore suggested that the camera and the associated distortions should be assessed first and foremost and, where possible, quantified, to determine the level of each type of distortion present within the footage. A review of the 'forensic image analysis' review is presented here. It will outline the image distortion types and detail the limitations of differing surveillance camera systems. The aim is to highlight various types of distortion present particularly from surveillance footage, as well as address gaps in current literature in relation to assessment of CCTV distortions in tandem with gait analysis. Future work will consider the anatomical assessment from surveillance footage. PMID- 29453009 TI - Advances in concrete materials for sewer systems affected by microbial induced concrete corrosion: A review. AB - Microbial induced concrete corrosion (MICC) is recognized as one of the main degradation mechanisms of subsurface infrastructure worldwide, raising the demand for sustainable construction materials in corrosive environments. This review aims to summarize the key research progress acquired during the last decade regarding the understanding of MICC reaction mechanisms and the development of durable materials from an interdisciplinary perspective. Special focus was laid on aspects governing concrete - micoorganisms interaction since being the central process steering biogenic acid corrosion. The insufficient knowledge regarding the latter is proposed as a central reason for insufficient progress in tailored material development for aggressive wastewater systems. To date no cement-based material exists, suitable to withstand the aggressive conditions related to MICC over its entire service life. Research is in particular needed on the impact of physiochemical material parameters on microbial community structure, growth characteristics and limitations within individual concrete speciation. Herein an interdisciplinary approach is presented by combining results from material sciences, microbiology, mineralogy and hydrochemistry to stimulate the development of novel and sustainable materials and mitigation strategies for MICC. For instance, the application of antibacteriostatic agents is introduced as an effective instrument to limit microbial growth on concrete surfaces in aggressive sewer environments. Additionally, geopolymer concretes are introduced as highly resistent in acid environments, thus representing a possible green alternative to conventional cement-based construction materials.

AB - BACKGROUND: Social networking sites (SNSs), which provide abundant social comparison opportunities, are ubiquitous around the world, especially among adolescents. In China, Qzone stands out as the most popular SNS. Due to the opportunity it provides for meticulous self-presentation, SNS may give the impression that others are doing better, which is detrimental to individuals' well-being. Based on social comparison theory, the current study aimed to investigate the association between Chinese adolescents' SNS (Qzone) use and depression, as well as the mediating role of negative social comparison and the moderating role of self-esteem. METHOD: A total of 764 adolescents (aged 12-18 years, M = 14.23, SD = 1.75), who had an active Qzone account, were recruited voluntarily to complete questionnaires on Qzone use intensity, negative social comparison on Qzone, self-esteem, and depression. RESULTS: More intense Qzone use was associated with higher level of negative social comparison on Qzone, which fully mediated the association between Qzone use and depression. Moreover, the mediating effect of negative social comparison on Qzone was moderated by self esteem. The specific link between Qzone use and negative social comparison was weaker among adolescents with high self-esteem than those with low self-esteem. LIMITATIONS: As all the data in this study were self-reported and cross sectional, causal associations cannot be identified. Additionally, the specific activities on SNS were not identified. CONCLUSIONS: Negative social comparison may be a key factor and mechanism accounting for the positive association between SNS use and depression, while self-esteem could protect adolescents from the adverse outcome of SNS use.

AB - BACKGROUND: Both, maternal borderline personality disorder (BPD) and maternal major depressive disorder (MDD) are often associated with adverse consequences for children, including increased risk for child behavior problems. Reduced maternal emotional availability might play a critical role in transmitting maternal psychopathology on the child. Our aim was to investigate the association between emotional availability and maternal BPD and MDD in remission (rMDD), and if this interrelatedness mediates the association between maternal mental disorders and child behavior problems. METHODS: The interaction of 178 mother child dyads was assessed during a play situation using the Emotional Availability Scales. Children were between 5 and 12 years old. Regression analyses were used to investigate the impact of maternal BPD and maternal rMDD on emotional availability. Ordinary least squares regression analyses using bootstrapping were conducted to investigate the mediating effect of emotional availability on the association between maternal mental disorders and child behavior problems. RESULTS: Mothers with BPD showed increased hostility during mother-child interaction, whereas history of MDD was associated with reduced sensitivity. Maternal hostility was a mediator between maternal BPD and number of child psychiatric disorders, as well as externalizing and internalizing behavior. Maternal sensitivity mediated the association between maternal rMDD and number of child psychiatric disorders, as well as internalizing child behavior. CONCLUSIONS: Our data suggest that mothers with BPD show a qualitatively different pattern of emotional availability compared to mothers with rMDD. These patterns might reflect two separate pathways of transgenerational transmission of aspects of maternal mental disorders, where intervention and training programs could start: maternal rMDD impacts on child behavior problems via reduced sensitivity, and maternal BPD via increased hostility, which could both be addressed with specific therapeutic interventions.

AB - This study focuses on the treatment of both organic and metallic pollution in the Staoueli landfill leachate. This leachate contains a large amount of organic and inorganic matter and it must imperatively be treated before being released into the environment. Our work presents a comparative study between two membrane sequenced batch bioreactors (B2 contains indigenous leachate bacteria and B1 contains activated sludge). The purpose is to assess the best treatment to use, one that allows the reduction of the polluting load of the leachate and a reduction of membrane fouling. Performances were evaluated by measuring the chemical oxygen demand (COD) and the metal content of the leachate (zinc, iron). The results showed a similar COD removal efficiency in B2 (95%) and B1 (93%). Coupling the bioreactors with an ultrafiltration process allowed a notable reduction in zinc and iron concentrations: Fe of 35% and Zn of 78% for B1UF, and Fe of 71% and Zn of 74% for B2UF. PMID- 29453013 TI - AERMOD as a Gaussian dispersion model for planning tracer gas dispersion tests for landfill methane emission quantification. AB - The measurement of methane emissions from landfills is important to the understanding of landfills' contribution to greenhouse gas emissions. The Tracer Dispersion Method (TDM) is becoming widely accepted as a technique, which allows landfill emissions to be quantified accurately provided that measurements are taken where the plumes of a released tracer-gas and landfill-gas are well-mixed. However, the distance at which full mixing of the gases occurs is generally unknown prior to any experimental campaign. To overcome this problem the present paper demonstrates that, for any specific TDM application, a simple Gaussian dispersion model (AERMOD) can be run beforehand to help determine the distance from the source at which full mixing conditions occur, and the likely associated measurement errors. An AERMOD model was created to simulate a series of TDM trials carried out at a UK landfill, and was benchmarked against the experimental data obtained. The model was used to investigate the impact of different factors (e.g. tracer cylinder placements, wind directions, atmospheric stability parameters) on TDM results to identify appropriate experimental set ups for different conditions. The contribution of incomplete vertical mixing of tracer and landfill gas on TDM measurement error was explored using the model. It was observed that full mixing conditions at ground level do not imply full mixing over the entire plume height. However, when full mixing conditions were satisfied at ground level, then the error introduced by variations in mixing higher up were always less than 10%.

AB - Cleaning and disposal of illegal dumping at charitable collection points costs charities and diverts funds from their charitable programs. However, there is no published literature that attempts to better understand this problem. The current study assesses site-specific characteristics, community level indicators and sociodemographic factors as predictors of both charity stores and collection bin dumping in the metropolitan area of Perth, Australia. Multiple regression analyses revealed that higher levels of dumping at stores were predicted by being open on Sundays, the presence of gates/fencing, bringing bins in at night, greater 5-year mobility and lower levels of education and occupation in the area. The analysis also suggests that preventative measures have not necessarily been effective at reducing the amount of illegal dumping at stores. For charity bins, significant predictors of higher levels of dumping included private land ownership, if the site is shared with bins from another charity, the number of bins at the site, the number of days serviced per week, if the bin/s are located at a park/reserve and greater 5-year mobility. These results indicate that there is a combination of site-specific characteristics and community level indicators that play a role in illegal dumping at charitable collection points and indicate the type of interventions which may be successful in reducing illegal dumping. These may include improved maintenance, better placement of bins and signage and collaborations with real estate agents. PMID- 29453015 TI - Metabolomic profiling of Campylobacter jejuni with resistance gene ermB by ultra high performance liquid chromatography-quadrupole time-of-flight mass spectrometry and tandem quadrupole mass spectrometry. AB - The metabolome changes of Campylobacter jejuni with resistant gene ermB remain unclear. Here, we described an untargeted metabolomic workflow based on ultra high performance liquid chromatography-quadrupole time-of-flight mass spectrometry to investigate the metabolites perturbations mediated by ermB in C. jejuni. After optimization of extractants and chromatographic conditions, the combination of 100% methanol extraction with a 12 min gradient by C18 column was adopted for untargeted metabolomic profiling in reversed phase separation. Meanwhile, 60% methanol extraction followed by a 14 min separation using hydrophilic interaction chromatography column was suitable to complementally expand the metabolite coverage of C. jejuni. Multivariate statistical analysis was performed by means of orthogonal projection to latent structures-discriminant analysis to select metabolic features. The selected features were further confirmed by ultra-high performance liquid chromatography-tandem quadrupole mass spectrometry. A total of thirty-six differential metabolites between the susceptible strain (C. jejuni NCTC 11168) and resistant stain (C. jejuni NCTC 11168 with ermB) were identified. These pivotal metabolites were primarily participated in biological processes as cell signaling, membrane integrity/stability, fuel and energy source/storage and nutrient. The biofilm formation capability of resistant strain was inferior to that of susceptible strain, confirming the influence of ermB on membrane integrity/stability of C. jejuni. Our findings revealed important metabolic regulatory pathways associated with resistant C. jejuni with ermB. PMID- 29453016 TI - Metabolic profiling of Gegenqinlian decoction in rat plasma, urine, bile and feces after oral administration by ultra high performance liquid chromatography coupled with Fourier transform ion cyclotron resonance mass spectrometry. AB - Gegenqinlian decoction (GQLD) as a traditional Chinese medical (TCM) prescription is made from four Chinese herbs and has been used for centuries to treat pyrexia and diarrhea. In this work, an ultra-high performance liquid chromatography coupled with Fourier transform ion cyclotron resonance mass spectrometry (UHPLC FT-ICR-MS) method was established to profile the metabolic fate of GQLD in rat plasma, urine, bile and feces. The analysis was performed on a Waters Acquity UPLC HSS T3 column (2.1 mm * 100 mm, 1.8 MUm) at 35 degrees C within 25 min. A total of 174 compounds mainly including flavonoids, alkaloids and triterpenoids in rat plasma, urine, bile and feces after oral administration of GQLD were identified or tentatively characterized by comparison with retention times, accurate mass within 5 ppm error and their characteristic MS fragmentation ions. Among compounds in rats, 107 compounds are prototypes and 67 compounds are metabolites. Results demonstrated that metabolic pathways of GQLD in rats included methylation, demethylation, hydrogenation, hydrolysis, hydroxylation, methoxylation, sulfate conjugation and glucuronide conjugation. A clear understanding of the absorption and metabolism of GQLD is very important in its rational clinical use and pharmacological research. These findings enhance our understanding of the metabolism and effective forms of GQLD.

AB - Acute rhinosinusitis is an important health problem. Even though its frequency is not well documented in our country?, the economic burden it bears is not insignificant as it notably alters the quality of life of affected patients. Its diagnosis is generally clinical in nature, with further studies reserved only for the differential diagnoses of complications or tumour-like processes. The most frequent causes are viral infections, although Streptococcus pneumoniae and Haemophilus influenzae are the most commonly isolated bacterial agents. Although complications are uncommon nowadays, they can be serious when they occur, and commonly include orbital infections, closely followed in frequency by intracranial and bone infections. Treatment should consist of symptomatic measures, like saline rinses and antibiotics in cases of bacterial origin.

PMID- 29453020 TI - 2018 consensus of the Taiwan Society of Cardiology and the Diabetes Association of Republic of China (Taiwan) on the pharmacological management of patients with type 2 diabetes and cardiovascular diseases. AB - The global incidence and prevalence of type 2 diabetes have been escalating in recent decades. Patients with type 2 diabetes have an increased risk of atherosclerotic cardiovascular disease (ASCVD). About two-thirds of death in type 2 diabetes are due to ASCVD, including 40% from coronary heart disease (CHD), 15% from heart failure (HF), and 10% from stroke. The association between hyperglycemia and elevated CV risk has been demonstrated in multiple cohort studies. However, clinical trials of intensive glucose reduction did not significantly reduce macrovascular outcomes. It remains unclear whether the absence of demonstrable benefits is attributed to the inclusion of patients with far advanced ASCVD in whom a short treatment period is barely enough for CV protective effects to be shown, or complications associated with the treatment such as hypoglycemia hamper the beneficial effects to manifest, or simply glucose lowering per se is ineffective. Since the US FDA issued a mandate in December 2008 that every new anti-diabetic agent requires rigorous assessments of its CV safety, there have been more than 200,000 patients enrolled in a number of randomized controlled trials (RCTs), and around half of them have been completed and published. The results of these CV outcome trials are important for clinicians in their clinical practice, and also provide an opportunity for academic society to formulate treatment guidelines or consensus to provide specific recommendations for glucose control in various CV diseases. The Taiwan Society of Cardiology (TSOC) and the Diabetes Association of Republic of China (DAROC), aiming to formulate a treatment consensus in type 2 diabetic patients with CVD, have appointed a jointed consensus group for the 2018 Consensus of TSOC/DAROC (Taiwan) on the Pharmacological Management of Patients with Type 2 Diabetes and CV Diseases. The consensus is comprised of 5 major parts: 1) Treatment of diabetes in patients with hypertension, 2) Treatment of diabetes in patients with CHD, 3) Treatment of diabetes in patients with stage 3 chronic kidney disease, 4) Treatment of diabetes in patients with a history of stroke, and 5) Treatment of diabetes in patients with HF. The members of the consensus group comprehensively reviewed all the evidence, mainly RCTs, and also included meta-analyses, cohort studies, and studies using claim data. The treatment targets of HbA1c were provided. The anti-diabetic agents were ranked according to their clinical evidence. The consensus is not mandatory. The final decision may need to be individualized and based on clinicians' discretion. PMID- 29453021 TI - Towards sustainable feedstocks: A guide to electron donors for microbial carbon fixation. AB - The replacement of fossil and agricultural feedstocks with sustainable alternatives for the production of chemicals and fuels is a societal and environmental necessity. This challenge can be tackled by using inorganic or one carbon compounds as electron donors for microbial CO2 fixation and bioproduction. Yet, considering the wide array of microbial electron donors, which are the best suited for bioindustry? Here, we propose criteria to evaluate these compounds, considering factors such as production methods, physicochemical properties, and microbial utilization. H2, CO, and formate emerge as the most promising electron donors as they can be produced electrochemically at high efficiency and, importantly, have reduction potentials low enough to directly reduce the cellular electron carriers. Still, further research towards the production and utilization of other electron donors-especially phosphite-might unlock the full potential of microbial CO2 fixation and bioproduction. PMID- 29453022 TI - Exploring factors that influence students' attitudes toward midwifery in Jordan: Measuring psychometric properties of a newly developed tool. AB - Students' professional choice to proceed in midwifery is influenced by many factors. This study validated an instrument developed to assess students' attitudes toward midwifery in Jordan. It also addressed the motivating and de motivating factors influencing students' decision concerning joining and continuing in midwifery. A descriptive, cross-section study was conducted on a convenience sample of 374 midwifery students representing private, governmental, and military midwifery colleges. The researchers developed the study questionnaire through conducting a comprehensive literature review, organizing common themes and consulting experts. Exploratory factor analysis and tests of normality and reliability, including Cronbach's Alpha and Bartlett's test, were used in the analysis. The result was three factors were explained by 23 items. They were as follows: professional knowledge, professional motivation factors, and de-motivating professional factors. The first 8 items explained nearly 61% of the variance. Cronbach's Alpha was 0.834 with a range of 0.835-0.839. The Spearman-Brown coefficient was 0.81 and Guttman Split-Half coefficient was 0.83. Issues of reliability and validity require a repetitive process of testing under a range of circumstances to ensure both stability and representation of the construct. However, addressing factors found to have impact of students' decisions is crucial to improve retention of high quality students. PMID- 29453023 TI - Implications of altered maternal cytokine concentrations on infant outcomes in children with prenatal alcohol exposure. AB - Excessive alcohol consumption has been shown to increase serum plasma levels of numerous immune cytokines. Maternal immune activation and elevated cytokines have been implicated in certain neurological disorders (e.g., autism and schizophrenia) in the offspring. We investigated the hypothesis that elevated cytokines during pregnancy are a risk factor in women who gave birth to a child with Fetal Alcohol Spectrum Disorder (FASD) or a child with neurobehavioral impairment, regardless of prenatal alcohol exposure. Moderate to heavy alcohol exposed (AE) (N = 149) and low or no alcohol-exposed (LNA) (N = 92) women were recruited into the study during mid pregnancy (mean of 19.8 +/- 5.8 weeks' gestation) in two regions of Ukraine: Khmelnytsky and Rivne. Maternal blood samples were obtained at enrollment into the study at early to mid-pregnancy and during a third-trimester follow-up visit and analyzed for plasma cytokines. Children were examined at 6 and/or 12 months of age and were classified as having FASD if their mothers reported alcohol use and if they had at least one standardized score (Bayley Scales of Infant Development II Mental Development Index [MDI], or Psychomotor Development Index [PDI]) below 85 with the presence or absence of physical features of FASD. In multivariate analyses of maternal cytokine levels in relation to infant MDI and PDI scores in the entire sample, increases in the ratio of TNF-alpha/IL-10 and IL-6/IL-10 were negatively associated with PDI scores at 6 months (p = 0.020 and p = 0.036, respectively) and 12 months (p = 0.043 and p = 0.029, respectively), and with MDI scores at 12 months (p = 0.013 and p = 0.050, respectively). A reduction in the odds ratio of having an FASD child was observed with increasing levels of IL-1beta, IL-2, IL-4, IL-6, and IL-10 in early to mid-pregnancy and IL-1beta and IL-10 during late pregnancy. However, women that failed to increase IL-10 levels in the third trimester in order to maintain the balance of pro- and anti-inflammatory cytokines had an elevated risk of having an FASD child, specifically a significant increase in the odds ratio of FASD with every one-unit log increase in late pregnancy TNF-alpha/IL-10 levels (aOR: 1.654, CI: 1.096-2.495, p = 0.017). These data support the concept that disruptions in the balance between pro- and anti-inflammatory cytokines may contribute to neurobehavioral impairment and alter the risk of FASD. PMID- 29453024 TI - Simultaneous determination of ibuprofen and its metabolites in complex equine urine matrices by GC-EI-MS in excretion study in view of doping control. AB - A novel assay for the simultaneous determination of ibuprofen (IBU) and its four probable metabolites, 1-hydroxyibuprofen (1-OH IBU), 2-hydroxyibuprofen (2-OH IBU), 3-hydroxyibuprofen (3-OH IBU) and carboxyibuprofen (CBX IBU) in equine urine samples with the application of Gas Chromatography-Electron Ionization-Mass Spectrometry (GC-EI-MS) has been developed and elaborated. The new approach for sample preparation including minimizing matrix effects by the application of weak cation exchange solid-phase extraction together with strong cation exchange solid phase extraction has been applied. The GC-EI-MS method was validated to demonstrate specificity, matrix effect, linearity, limit of detection (LOD) and quantification (LOQ), precision, trueness, carry-over and stability by using the matrix-matched quality control samples. Additionally, extraction yield was evaluated. The assay achieved the LOQ of 1.75 MUg mL-1, 0.62 MUg mL-1, 4.15 MUg mL-1, 0.58 MUg mL-1 and 4.04 MUg mL-1 for IBU, 1-OH IBU, 2-OH IBU, 3-OH IBU and CBX IBU, respectively. The developed method has been successfully applied to the excretion study in horses, in which a single oral IBU dose was administered to twelve horses (mares and geldings) and equine urine samples were collected for 5 or 6 days after the drug administration. Data on the detection and determination of three IBU metabolites, 2-OH IBU, 3-OH IBU and CBX IBU in equine urine samples has been presented for the first time. The obtained results indicated the rapid excretion of IBU and its metabolites that were detectable only in the first day after the drug administration. IBU was mainly the most abundant compound detected in equine urine samples (with two exceptions in the case of samples collected from two horses, for which the highest instrumental responses were obtained for CBX IBU). The received results have indicated that two major IBU metabolites, CBX IBU and 2-OH IBU can be important markers for the IBU abuse in view of doping control in equestrian sports. PMID- 29453026 TI - Assessment of titanium metallization thin film deposited on alumina substrate: Microstructure and nano-indentation. AB - Surface titanium (Ti) metallization was conducted on alumina (Al2O3) through chemical vapor deposition (CVD) method derived from non-contact pack cementation. The effects of different deposition temperature (1000 degrees C, 1050 degrees C, and 1100 degrees C) were examined in this scenario. The morphology, phase composition, and interfacial defects of the resulting films were systematically investigated through scanning electron microscopy, energy dispersive spectrometry, and X-ray diffraction. The nanomechanical characterization of the proposed thin films was evaluated by conducting nano-indentation tests at different depths. The results revealed that uniform Ti films were coated on the Al2O3 substrate. During coating, the atoms on the matrix surface were driven to form different structure due to different deposition temperature, leading to disparate morphologies of the surface and the interface, which consequently influenced the binding force between the film and the substrate. Moreover, the nanomechanical properties were found to be related to the internal and interface structure. Decreased modulus and hardness were obtained for metallization films treated at 1050 degrees C, and plastic deformation was the main deformation pattern. PMID- 29453025 TI - Material properties of the brain in injury-relevant conditions - Experiments and computational modeling. AB - Material properties of the brain have been extensively studied but remain poorly characterized. The vast variations in constitutive models and material constants are well documented. However, no study exists to translate the variations into disparities in impact-induced brain strains most relevant to brain injury. Here, we reviewed a subset of injury-relevant brain material properties either characterized in experiments or adopted in recent head injury models. To highlight how variations in measured brain material properties manifested in simulated brain strains, we selected six experiments that have provided a complete set of brain material model and constants to implement a common head injury model. Responses resulting from two extreme events representing a high rate cadaveric head impact and a low-rate in vivo head rotation, respectively, varied substantially. We hypothesized, and further confirmed, that the time varying shear moduli at the appropriate time scales (e.g., ~5 ms and ~40 ms corresponding to the impulse durations of the major acceleration peaks for the two impacts, respectively), rather than the initial or long-term shear moduli, were the most indicative of impact-induced brain strains. These results underscored the need to implement measured brain material properties into an actual head injury model for evaluation. They may also provide guidelines to better characterize brain material properties in future experiments and head injury models. Finally, our finding provided a practical solution to satisfy head injury model validation requirements at both ends of the impact severity spectrum. This would improve the confidence in model simulation performance across a range of time scales relevant to concussion and sub-concussion in the real-world. PMID- 29453027 TI - Effects of microstructure transformation on mechanical properties, corrosion behaviors of Mg-Zn-Mn-Ca alloys in simulated body fluid. AB - Magnesium and its alloys have unique advantages to act as resorbable bone fixation materials, due to their moderate mechanical properties and biocompatibility, which are similar to those of human tissue. However, early resorption and insufficient mechanical strength are the main problems that hinder their application. Herein, the effects of microstructure transformation on the mechanical properties and corrosion performance of Mg-Zn-Mn-Ca were investigated with electrochemical and immersion measurements at 37 degrees C in a simulated body fluid (SBF). The results showed that the number density of Ca2Mg6Zn3/Mg2Ca precipitates was remarkably reduced and grain sizes were gradually increased as the temperature increased. The alloy that received the 420 degrees C/24 h treatment demonstrated the best mechanical properties and lowest corrosion rate (5.94 mm/a) as well as presented a compact and denser film than the others. The improvement in mechanical properties could be explained by the eutectic compounds and phases (Mg2Ca/Ca2Mg6Zn3) gradually dissolving into a matrix, which caused severely lattice distortion and facilitated structural re-arrangement of the increased Ca solute. Moreover, the difference in potential between the precipitates and the matrix is the main essence for micro-galvanic corrosion formation as well as accelerated the dissolution activity and current exchange density at the Mg/electrolyte interface. As a result, the best Mg alloys corrosion resistance must be matched with a moderate grain size and phase volume fractions. PMID- 29453028 TI - Transposons: a blessing curse. AB - The genomes of most plant species are dominated by transposable elements (TEs). Once considered as 'junk DNA', TEs are now known to have a major role in driving genome evolution. Over the last decade, it has become apparent that some stress conditions and other environmental stimuli can drive bursts of activity of certain TE families and consequently new TE insertions. These can give rise to altered gene expression patterns and phenotypes, with new TE insertions sometimes causing flanking genes to become transcriptionally responsive to the same stress conditions that activated the TE in the first place. Such connections between TE mediated increases in diversity and an accelerated rate of genome evolution provide powerful mechanisms for plants to adapt more rapidly to new environmental conditions. This review will focus on environmentally induced transposition, the mechanisms by which it alters gene expression, and the consequences for plant genome evolution and breeding. PMID- 29453029 TI - Systems biology of the human microbiome. AB - Recent research has shown that the microbiome-a collection of microorganisms, including bacteria, fungi, and viruses, living on and in a host-are of extraordinary importance in human health, even from conception and development in the uterus. Therefore, to further our ability to diagnose disease, to predict treatment outcomes, and to identify novel therapeutics, it is essential to include microbiome and microbial metabolic biomarkers in Systems Biology investigations. In clinical studies or, more precisely, Systems Medicine approaches, we can use the diversity and individual characteristics of the personal microbiome to enhance our resolution for patient stratification. In this review, we explore several Systems Medicine approaches, including Microbiome Wide Association Studies to understand the role of the human microbiome in health and disease, with a focus on 'preventive medicine' or P4 (i.e., personalized, predictive, preventive, participatory) medicine. PMID- 29453030 TI - Effects of triphenyltin on glycinergic transmission on rat spinal neurons. AB - Glycine is a fast inhibitory transmitter like gamma-aminobutyric acid in the mammalian spinal cord and brainstem, and it is involved in motor reflex, nociception, and neuronal development. Triphenyltin (TPT) is an organometallic compound causing environmental hazard to many wild creatures. Our previous findings show that TPT ultimately induces a drain and/or exhaustion of glutamate in excitatory presynaptic nerve terminals, resulted in blockage of neurotransmission as well as methylmercury. Therefore, we have investigated the neurotoxic mechanism how TPT modulates inhibitory glycinergic transmission in the synaptic bouton preparation of rat isolated spinal neurons using a patch clamp technique. TPT at environmentally relevant concentrations (3-300 nM) significantly increased the number of frequency of glycinergic spontaneous and miniature inhibitory postsynaptic currents (sIPSC and mIPSC) without affecting the current amplitude and decay time. The TPT effects were also observed in external Ca2+-free solution containing tetrodotoxin (TTX) but removed in Ca2+ free solution with both TTX and BAPTA-AM (Ca2+ chelator). On the other hand, the amplitude of glycinergic evoked inhibitory postsynaptic currents (eIPSCs) increased with decreasing failure rate (Rf) and paired pulse ratio (PPR) in the presence of 300 nM TPT. At a high concentration (1 uM), TPT completely blocked eIPSCs after a transient facilitation. Overall, these results suggest that TPT directly acts transmitter-releasing machinery in glycinergic nerve terminals. Effects of TPT on the nerve terminals releasing fast transmitters were greater in the order of glycinergic > glutamatergic > GABAergic ones. Thus, TPT is supposed to cause a strong synaptic modulations on glycinergic neurotransmission in wild creatures. PMID- 29453031 TI - Spaces of hope? Youth perspectives on health and wellness in indigenous communities. AB - This article addresses an apparent paradox between academic and policy depictions of American Indian reservations as "broken" and "unhealthy" places, and Indigenous youth perceptions of reservations as spaces of "health" and "wellness." Public health literature often frames reservations as damaged, health denying places, chronicling the extraordinarily high rates of suicide, substance abuse, as well as vast health disparities. Despite these dire statistics, our research with Native youth in San Diego County found that young people chose to primarily emphasize their positive experiences with, and attachments to, their reservations. In this article, we share strength- and desire-based narratives to explore how reservations can serve as spaces of wellness for Indigenous youth, despite ongoing settler colonial harm. We seek to expand the discussion on the unintended consequences of deficit-centered scholarship by arguing that health research should also engage with the narratives of hope and desire that are reflective of the way many Native youth feel about their communities. In this article, we urge scholars and practitioners to rethink how we conduct health research to include methodologies that listen to the narratives and experiences of those who, day in and day out, navigate settler colonial landscapes, while continuing to create spaces of hope and healing. PMID- 29453032 TI - Impact of metformin on gastric adenocarcinoma survival: A Belgian population based study. AB - BACKGROUND: Preclinical studies have shown anticancer activities of metformin in gastric cancer and a recent epidemiological study showed a decrease in recurrence and mortality of gastric cancer in metformin users. This study aimed to assess the impact of metformin on gastric cancer survival in diabetic patients at a Belgian population level. METHODS: We conducted an observational, population based study by linking data of the Belgian Cancer Registry with medical claims data coming from the health insurance companies for patients diagnosed with stage I to III gastric adenocarcinoma between 2006 and 2012. Information on gastric cancer-specific deaths was retrieved from mortality records collected by regional governments. Time-dependent Cox regression models were used to calculate hazard ratios (HRs) and 95% confidence intervals (CI) for overall survival (OS) and cancer-specific mortality (CSS). RESULTS: In our population of 371 patients, a reduction in all-cause mortality was observed in metformin users (adjusted HR = 0.73, 95% CI: [0.52; 1.01], p = 0.06) but not for cancer specific mortality (adjusted HR = 0.86, 95% CI: [0.56; 1.33], p = 0.50). Pre-diagnosis exposure to metformin was associated with a significant improvement in OS (adjusted HR = 0.75, 95% CI: [0.57; 0.98], p = 0.04) that was not significant for CSS (adjusted HR = 0.89, 95% CI: [0.62; 1.28], p = 0.52). Moreover, no dose-response relationship between metformin use and either all-cause or cancer-specific mortality was observed. CONCLUSION: In the first population based study of metformin use in gastric cancer adenocarcinoma patients with previous diabetes, our findings suggest that metformin use might improve overall mortality. However, no such association was found for cancer-specific survival. Additional studies in other populations are required. PMID- 29453033 TI - The Social Attribution Task - Multiple Choice (SAT-MC): Psychometric comparison with social cognitive measures for schizophrenia research. AB - The Social Attribution Task-Multiple Choice (SAT-MC) tests the ability to extract social themes from viewed object motion. This form of animacy perception is thought to aid the development of social inference, but appears impaired in schizophrenia. The current study was undertaken to examine psychometric equivalence of two forms of the SAT-MC and to compare their performance against social cognitive tests recommended for schizophrenia research. Thirty-two schizophrenia (SZ) and 30 substance use disorder (SUD) participants completed both SAT-MC forms, the Bell-Lysaker Emotion Recognition Task (BLERT), Hinting Task, The Awareness of Social Inference Test (TASIT), Ambiguous Intentions and Hostility Questionnaire (AIHQ) and questionnaire measures of interpersonal function. Test sensitivity, construct and external validity, test-retest reliability, and internal consistency were evaluated. SZ scored significantly lower than SUD on both SAT-MC forms, each classifying ~60% of SZ as impaired, compared with ~30% of SUD. SAT-MC forms demonstrated good test-retest and parallel form reliability, minimal practice effect, high internal consistency, and similar patterns of correlation with social cognitive and external validity measures. The SAT-MC compared favorably to recommended social cognitive tests across psychometric features and, with exception of TASIT, was most sensitive to impairment in schizophrenia when compared to a chronic substance use sample.

Because attachment insecurity (vs security) is related to psychiatric disorders the objective was to study the attachment style in insomnia. To this aim sixty four subjects with Insomnia Disorder (DSM-5) and 38 good sleepers were evaluate in a cross-sectional study with: Attachment Style Questionnaire (ASQ), Arousal Predisposition Scale (APS), Pre-Sleep Arousal Scale (PSAS) and Difficulties in Emotion Regulation Scale (DERS). Differences in means between groups were assessed using t-test or Mann-Whitney U/Wilcoxon test. Linear/multiple regression analyses were performed. Subjects with insomnia (mean age 47.1 + 13 yrs) presented an insecure attachment style and higher scores in all the scales (ASQ, APS, PSAS, DERS p < 0.0001) than good sleepers (mean age 48.2 + 14 yrs). After taking into account anxiety/depressive symptoms, insecure attachment was related to hyperarousal trait (p = 0.02), pre-sleep hyperarousal (p = 0.04) and emotion dysregulation (p = 0.002). In conclusion subjects with insomnia showed an insecure attachment which was related to hyperarousal trait, pre-sleep hyperarousal and emotion dysregulation. It may intervene in the trajectory of insomnia starting from predisposition to perpetuation. Clinical implications are discussed.

AB - There is a strong correlation between neurocognition and social cognition. However, none of these studies have examined the key role of time consumption during social cognition tasks. Participants included 84 individuals with clinical high risk of psychosis (CHR), 95 healthy controls (HC), and 66 case controls (schizophrenia patients, SZ), who were assessed through the Reading-Mind-in-Eyes Tasks (RMET) with computerized recording of the response time (RT). Neurocognitive tests were also performed for the HC and CHR groups. A comparison of RMET performance revealed significantly lower scores in the SZ group compared to the HC group, with CHR individuals scoring between these two. However, both CHR and SZ subjects spent almost twice as long of the time on RMET compared to the HC subjects. Significant positive correlation was found between RMET accuracy and RT, though only in SZ patients. Taking the RT into consideration, the RMET performances were impacted by different neurocognition domains. Our findings provide new evidence about how time consumption in mind-reading may impact the relationship between social cognition and neurocognition, and we discuss the potential importance of recording the response time during social cognition assessment in individuals with early psychosis.

AB - Individuals with a history of non-suicidal self-injury (NSSI) are at alarmingly high risk for suicidal ideation (SI), planning (SP), and attempts (SA). Given these findings, research has begun to evaluate the features of this multi-faceted behavior that may be most important to assess when quantifying risk for SI, SP, and SA. However, no studies have examined the wide range of NSSI characteristics simultaneously when determining which NSSI features are most salient to suicide risk. The current study utilized three exploratory data mining techniques (elastic net regression, decision trees, random forests) to address these gaps in the literature. Undergraduates with a history of NSSI (N = 359) were administered measures assessing demographic variables, depression, and 58 NSSI characteristics (e.g., methods, frequency, functions, locations, scarring) as well as current SI, current SP, and SA history. Results suggested that depressive symptoms and the anti-suicide function of NSSI were the most important features for predicting SI and SP. The most important features in predicting SA were the anti-suicide function of NSSI, NSSI-related medical treatment, and NSSI scarring. Overall, results suggest that NSSI functions, scarring, and medical lethality may be more important to assess than commonly regarded NSSI severity indices when ascertaining suicide risk. PMID- 29453037 TI - Profile of psychiatric symptoms in methamphetamine users in China: Greater risk of psychiatric symptoms with a longer duration of use. AB - Chronic methamphetamine (MA) use is associated with psychiatric symptoms. This study explored pattern of co-occurring psychiatric symptoms in MA users and their relationship to duration of MA use. A cross-sectional study was conducted among MA users at the Shenzhen Compulsory Drug Detoxification Center from April 2012 to October 2015. The Positive and Negative Syndrome Scale, Hamilton Anxiety Scale, and Beck Depression Inventory were used to assess psychiatric symptoms. Among 1277 MA users, 57.6% participants had any type of psychiatric symptoms including depressive, anxiety and psychotic symptoms. A dose-response relationship was found between duration of MA use and risk of psychiatric symptoms. The odds ratios (OR) of depressive symptoms increased with the duration of MA use (1-5 years vs. < 1 year: 1.74 [95% CI, 1.24-2.42]; >= 5 years vs. < 1 year: 2.07 [1.19 3.61]), so did the ORs of co-occurring anxiety and depressive symptoms (1-5 years: 1.74 [1.20-2.51]; >= 5 years: 3.09 [1.76-5.40]). Methamphetamine-dependent individuals were four-times more likely to experience any type of psychiatric symptoms than non-dependent users. The prevalence of psychiatric symptoms was high in chronic MA users and increased with MA use duration. Early prevention and treatment strategies targeting both MA use and associated psychiatric symptoms are needed. PMID- 29453038 TI - Psychopathic personality traits as a form of dispositional capability for suicide. AB - The capability to enact lethal self-harm has recently been highlighted as a critical risk factor for suicidal behavior. Klonsky and May's (2015) three step theory of suicide (3ST) expanded upon the construct of the capability for suicide by dividing it into categories: dispositional, acquired, and practical. The current study examined constructs of Patrick and colleagues' (2009) triarchic model of psychopathy as indicators of dispositional capability in gun owners, a sample at heightened risk for death by suicide (Anestis and Houtsma, 2017). We anticipated that specific psychopathic traits would exhibit robust associations with other components of the capability for suicide. In a sample of 300 gun owning adults, Boldness was uniquely related to all indicators of practical capability in both male and female gun owners, and a Boldness*Meanness interaction predicted the highest levels of some capability components. These results are consistent with theoretical conceptualizations of the triarchic model. Our findings indicate that, among US gun owners, dispositional factors may impact comfort with and aptitude with guns, which may enhance our understanding of which gun owners are at the greatest risk of gun suicide should they develop suicidal thoughts. PMID- 29453039 TI - Tolerance for psychological pain and capability for suicide: Contributions to suicidal ideation and behavior. AB - Among people with suicide ideation most do not attempt suicide or die by suicide. In this online study of adult US Facebook users (n = 219), we examined capability for suicide, operationalized as fearlessness about death, and tolerance for psychological pain as potential variables that may explain why some people move from suicide ideation to suicidal behavior. Tolerance for psychological pain was significantly higher for participants who had never attempted suicide. Fearlessness about death was higher in participants who had attempted suicide, but not significantly. At high levels of psychological pain, one's belief in the ability to cope with psychological pain, a dimension of tolerance for psychological pain, was lower in participants with a history of suicide attempt than in participants who had never attempted suicide. The odds of suicidal desire were almost cut in half with each unit increase in participants' belief in their coping ability, whereas for each unit increase in fearlessness about death, the odds of suicidal desire increased by 65%. The Pearson correlation between tolerance for psychological pain and fearlessness about death was negligible. Our findings support a role for both tolerance for psychological pain and capability for suicide/fearlessness about death in the ideation-to-action framework of suicide. PMID- 29453040 TI - Illuminating ATOM: Taking time across the colour category border. AB - Walsh's A Theory Of Magnitude (ATOM) contends that we represent magnitudes such as number, space, time and luminance on a shared metric, such that "more" of one leads to the perception of "more" of the other (e.g. Walsh, 2003). In support of ATOM, participants have been shown to judge intervals between stimuli that are more discrepant in luminance as having a longer duration than intervals between stimuli whose luminance differs by a smaller degree (Xuan, Zhang, He, & Chen, 2007). We tested the potential limits to the ability of luminance to influence duration perception by investigating the possibility that the luminance-duration relationship might be interrupted by a concurrent change in the colour of that luminance. We showed native Greek and native English speakers sequences of stimuli that could be either light or dark versions of green or blue. Whereas for both groups a shift in green luminance does not comprise a categorical shift in colour, for Greek speakers shifts between light and dark blue cross a colour category boundary (ghalazio and ble respectively). We found that duration judgements were neither interrupted nor inflated by a shift in colour category. These results represent the first evidence that the influence of luminance change on duration perception is resistant to interference from discrete changes within the same perceptual input. PMID- 29453041 TI - MicroRNA signature of regulatory T cells in health and autoimmunity. AB - MicroRNAs (miRNAs) are small RNA molecules with regulatory functions on the expression of genes through binding directly to target messenger RNA (mRNA) transcripts, eventuating in gene expression suppression via translational hindrance and/or target mRNA cleavage. These molecules have been established to participate in numerous critical cellular settings, including differentiation, development, and function of immune cells. As an important suppressor cell of immune system, regulatory T cells (Tregs) are important in modulating the immune homeostasis as well as tolerance to self-antigens. Despite identification of numerous transcription factors, cytokines, and other mediators regulate the biology of Tregs, investigations have demonstrated that noncoding RNAs are involved in several mechanisms of the regulation of Treg cells. On the other side, dysregulation of expression of several miRNAs has been reported in Tregs, implicating to the impaired function of these regulatory cells, resulting in autoimmune and other immune-based disorders. In this review, we aim to go through the overall microRNA network and specific miRNAs that are involved in the development, differentiation, and function of Tregs. Moreover, an overview was provided with respect to the role of aberrant expression of miRNAs in Tregs of autoimmune diseases such as multiple sclerosis, systemic lupus erythematosus, rheumatoid arthritis, inflammatory bowel disease, diabetes, and psoriasis. PMID- 29453042 TI - Evaluation of the anti-hypertensive effect of Tengfu Jiangya tablet by combination of UPLC-Q-exactive-MS-based metabolomics and iTRAQ-based proteomics technology. AB - OBJECTIVE: Tengfu Jiangya tablet (TJT) is a traditional Chinese medicine formulation composed of Uncaria rhynchophylla and Semen raphani. It is a hospital preparation that is widely used in clinics for treating hypertension. A previous metabolomics study reported that TJT exerted a protective effect on hypertension by restoring impaired NO production, ameliorating the inflammatory state, and vascular remodeling. A clinical proteomics study also revealed five key target proteins during TJT intervention. This study aimed to integrate proteome and metabolome data sets for a holistic view of the molecular mechanisms of TJT in treating hypertension. METHODS: Serum samples from spontaneously hypertensive rats and Wistar Kyoto rats were analyzed using ultra-high performance liquid chromatography coupled to Q Exactive hybrid quadrupole-Orbitrap mass spectrometry (UPLC-Q-Exactive-MS)-based metabolomics technology and isobaric tags for relative and absolute quantitation (iTRAQ)-based quantitative proteomics technology. Moreover, we selected two candidate proteins and determined their expression levels in rat serum using an enzyme-linked immunosorbent assay (ELISA). RESULTS: A total of 20 potential biomarkers and 14 differential proteins in rat serum were identified. These substances were mainly involved in three biological pathways: the kallikrein-kinin pathway, the lipid metabolism pathway, and the PPARgamma signaling pathway. CONCLUSIONS: The results suggested that TJT could effectively treat hypertension, partially by regulating the above three metabolic pathways. The combination of proteomics and metabolomics provided a feasible method to uncover the underlying interventional effect and therapeutic mechanism of TJT on spontaneously hypertensive rats. PMID- 29453043 TI - Understanding of human ATP binding cassette superfamily and novel multidrug resistance modulators to overcome MDR. AB - Indeed, multi-drug resistance (MDR) is a significant obstacle to effective chemotherapy. The overexpression of ATP-binding cassette (ABC) membrane transporters is a principal cause of enhanced cytotoxic drug efflux and treatment failure in various types of cancers. At cellular level, the pumps of ABC family regulate the transportation of numerous substances including drugs in and out of the cells. In past, the overexpression of ABC pumps suggested a well-known mechanism of drug resistance in cancers as well as infectious diseases. In oncology, the search for new compounds for the inhibition of these hyperactive ABC pumps either genetically or functionally, growing interest to reverse multi drug resistance and increase chemotherapeutic effects. Several ABC pump inhibitor/modulators has been explored to address the cancer associated MDR. However, the clinical results are still disappointing and conventional chemotherapies are constantly failed in successful eradication of MDR tumors. In this context, the structural and functional understanding of different ATP pumps is most important. In this concise review, we elaborated basic crystal structure of ABC transporter proteins as well as its critical elements such as different domains, motifs as well as some important amino acids which are responsible for ATP binding and drug efflux as well as demonstrated an ATP-switch model employed by various ABC membrane transporters. Furthermore, we briefly summarized different newly identified MDR inhibitors/modulators, deployed alone or in combination with cytotoxic agents to deal with MDR in different types of cancers. PMID- 29453044 TI - Micro RNA-1298 opposes the effects of chronic oxidative stress on human trabecular meshwork cells via targeting on EIF4E3. AB - OBJECTIVE: This study aimed to investigate the effect and potential mechanism of miR-1298 in the progression of human trabecular meshwork (HTM) cells. MATERIAL AND METHODS: Expression of miR-1298 was assessed by quantitative real time PCR (qRT-PCR), as well as in HTM-1 and HTM-2 cells. Mature miR-1298 mimic, miR-1298 inhibitor, and si-EIF4E3 and their corresponding controls were transfected into HTM-1 and HTM-2 to obtain stable HTM cells. Luciferase reporter assay was used to verify regulation between miR-1298 and EIF4E3. Cytotoxicity and Oxidative damage were assessed using commercial kits, and apoptosis was determined using flow cytometry. ECM and apoptosis related factors were determined using qRT-PCR and western blotting, as well as the pathway related factors. RESULTS: The expression of miR-1298 was significantly decreased both in glaucoma and HTM cells. MiR-1298 mimic could significantly inhibit the increase of cytotoxicity, apoptosis, accumulation of carbonylated proteins and ECM induced by COS, but miR-1298 inhibitor could obviously promote the increase effects caused by COS in HTM cells. EIF4E3 was a downstream target of miR-1298. Sliced EIF4E3 could significantly inhibit the increase effects induced miR-1298 inhibitor in HTM cells under COS. The expression levels of TGF-beta2 and Smad4 were significantly increased, and Wnt3a and beta-cantenin were obviously decreased under COS, and miR-1298 inhibitor could markedly promote this increase effect, while sliced EIF4E3 could reverse the effect of miR-1298 under COS. CONCLUSIONS: miR-1298 could protect HTM cells to against damage caused by COS via inhibiting TGF beta2/Smad4 pathway and activating canonical Wnt pathway. PMID- 29453045 TI - Activation of PPARgamma mediates icaritin-induced cell cycle arrest and apoptosis in glioblastoma multiforme. AB - BACKGROUND: Glioblastoma multiforme (GBM) is the most prevalent primary malignancy of the brain. This study was designed to investigate whether icaritin exerts anti-neoplastic activity against GBM in vitro. MATERIALS AND METHODS: Cell Counting Kit-8 (CCK-8) assay was utilized to examine the viability of GBM cells. The apoptotic cell population was measured by flow cytometry analysis. Cell cycle distribution was detected by flow cytometry as well. Western blot analysis was performed to examine the level of biomarker proteins in GBM cells. Levels of PPARgamma mRNA and protein were detected by qPCR and western blot analysis, respectively. To examine the role of PPARgamma in the anti-neoplastic activity of icaritin, PPARgamma antagonist GW9662 or PPARgamma siRNA was used. The activity of PPARgamma was determined by DNA binding and luciferase assays. RESULTS: Our findings revealed that icaritin markedly suppresses cell growth in a dose dependent and time-dependent fashion. The cell population at the G0/G1 phase of the cell cycle was significantly increased following icaritin treatment. Meanwhile, icaritin promoted apoptotic cell death in T98G and U87MG cells. Further investigation showed upregulation of PPARgamma played a key role in the anti-neoplastic activities of icaritin. Moreover, our result demonstrated activation of AMPK signaling by icaritin mediated the modulatory effect of icaritin on PPARgamma. CONCLUSION: Our results suggest the PPARgamma may mediate anti-neoplastic activities against GBM. PMID- 29453046 TI - Molecular chemoprevention by morin - A plant flavonoid that targets nuclear factor kappa B in experimental colon cancer. AB - Colorectal cancer is the third most common cancer worldwide. The development of effective, inexpensive and safe chemopreventive agents would be of great benefit as it involves use of natural products to prevent or suppress the progression of precursor lesions. Morin a flavonoid found in figs (Ficus carica) and other plants is shown to inhibit 1,2-dimethylhydrazine (DMH) induced colon cancer progression in a short term and long term model of colon cancer rats; however, the molecular target for the colon cancer chemoprotective efficacy of morin is yet to be discovered. The present study aims to explore the molecular basis of how morin contributes to the chemoprevention with a focus on NF-kappaB signaling pathway. The effect of morin on NF-kappaB signaling in DMH-induced carcinogenic events such as inflammation and apoptosis were analyzed by studying the histopathological analysis using Hematoxylin and Eosin staining (H &E), mRNA expression using q-PCR, protein expression using Immunohistochemistry (IHC) and western blot. Morin supplementation to DMH administered rats down regulated NF kappaB pathway and its downstream inflammatory mediators like tumor necrosis factor alpha (TNF-alpha), interleukin 6 (IL-6), cyclooxygenase 2 (COX-2) and prostaglandin (PGE-2). Morin supplementation to DMH administered rats alters BAX/BCL2 ratio favoring apoptosis in carcinogen treated rats. Our findings explored that molecular chemoprevention of morin targets NF-kappaB and acts as a potent anti-inflammatory and pro-apoptotic agent for colon cancer prevention. PMID- 29453047 TI - Influence of potassium hydroxide activation on characteristics and environmental risk of heavy metals in chars derived from municipal sewage sludge. AB - To investigate the influence of KOH activation on characteristics and environmental risk of heavy metals in chars, sludge was pyrolyzed with varying amount of KOH. The analyzation of characteristics and potential ecological risk evaluation of heavy metals were conducted by surface area analyzer, FTIR, XRD and BCR sequential extraction. The activated chars have higher surface area and lower content of silica compared to those without being activated. The activation of KOH promoted residual fraction of Cd, meanwhile, Zinc, Cr, Ni and Mn were converted to relatively unstable fractions (F2 and F3). The results of risk assessment indicated that the potential ecological risk level of Cd was reduced in activated chars, while risk level of Zn, Cr, Ni and Mn were increased after pyrolysis with KOH activation. The potential ecological risk of heavy metals in activated chars was further declined, and the risk level transformed from moderate to low. PMID- 29453048 TI - A system composed of a biofilm electrode reactor and a microbial fuel cell constructed wetland exhibited efficient sulfamethoxazole removal but induced sul genes. AB - The aim of this work was to study sulfamethoxazole (SMX) removal efficiency and fate of corresponding sul genes in a stacked microbial fuel cell-constructed wetland coupled biofilm electrode reactor system (MFC-CW-BER). Findings showed that two stacked MFC-CWs could provide a relatively stable electricity supply to support the biofilm for SMX removal. Excellent SMX removal (>99.29%) was obtained in the BER-MFC-CW. Compared with the 2000 ug L-1 SMX influent, the relative abundance of the sul genes in biofilm media and effluent was enhanced with continuously high concentrations of SMX (4000 MUg L-1). The relative abundances of sul genes in biofilm media and effluent increased as the hydraulic retention time decreased. However, there was no obvious variation in the relative abundance of sul genes in the effluent from MFC-CWs. No effect could be observe of the direct voltage and bioelectricity on the relative abundance of the sul genes in the BER. PMID- 29453049 TI - One-step conversion of agro-wastes to nanoporous carbons: Role in separation of greenhouse gases. AB - Highly microporous carbons have been synthesized from four types of agro-wastes of lignin, walnut shells, orange peels and apricot seeds by one-step carbonization/activation with potassium hydroxide (KOH) in varying ratios. The resultant carbons demonstrated BET specific surface areas of 727-2254 m2/g, and total pore volumes 0.34-1.14 cm3/g. These are higher than the majority of agro waste derived carbons reported in the literature. For all the carbons, CO2 adsorption at 298 K was higher than SF6 followed by N2 suggesting a possible separation of CO2 and SF6 from N2. The adsorbed amounts of CO2 at 298 K and 273 K and at pressures up to 760 Torr were 7.24 and 9.4 mmol/g, respectively which, to the best of our knowledge, are the highest CO2 uptakes in these temperatures by any carbon material reported so far. For all the gases, selectivity, mixed adsorption isotherms and adsorption breakthrough have been simulated from experimental data. PMID- 29453050 TI - Enhancement in the aromatic yield from the catalytic fast pyrolysis of rice straw over hexadecyl trimethyl ammonium bromide modified hierarchical HZSM-5. AB - Modified H-type ZSM-5 (HZSM-5) catalysts were prepared using hexadecyl trimethyl ammonium bromide (CTAB) as mesopore templates to enhance the activity for the catalytic fast pyrolysis of rice straw for aromatics compounds. A certain quantity of CTAB added into the HZSM-5 (HZ) forming hierarchical structure exhibited an improvement in the yield of the aromatics and a decrease in the yield of coke in comparison with that of bare HZ. In contrast, excessive CTAB addition resulted in a decrease in aromatic yield and an increase in coke yield. The effects of crystallinity, textural properties, morphological structure and acidity distribution on the production of aromatic compounds were measured by XRD, BET, TEM and NH3-TPD. The good crystallinity, small amount of mesopore formation and highest total acidity discovered in HZ-0.01 (the mole ratio of CTAB/SiO2 is 0.01) provided the highest aromatic compound yield of 26.8% and the lowest coke yield of 39.2%. PMID- 29453051 TI - HNO3 modified biochars for uranium (VI) removal from aqueous solution. AB - The HNO3 treatment was used to chemically modify the biochars produced from wheat straw (WH) and cow manure for U(VI) removal from aqueous solution. Macroscopic experiments proved that the enrichment of U(VI) on the biochars was regulated by surface complexation and electrostatic interactions. FTIR and XPS analyses confirmed that the highly efficient adsorption of U(VI) was due to the carboxyl groups on the biochar surfaces. The reducing agents of the R-CH2OH groups facilitated U(VI) adsorption on the untreated biochars. Owing to the higher contents of surface COO groups and more negative surface charge, the modified biochars showed enhanced U(VI) adsorption ability than the untreated ones. The maximum adsorption capacity of U(VI) by the oxidized WH was calculated to be 355.6 mg/g at pH 4.5 and 298 K, which was an improvement of 40 times relative to the untreated WH and was higher than that of most carbon-based adsorbents. PMID- 29453052 TI - Ac-LVFFARK-NH2 conjugation to beta-cyclodextrin exhibits significantly enhanced performance on inhibiting amyloid beta-protein fibrillogenesis and cytotoxicity. AB - Inhibition of amyloid beta-protein (Abeta) aggregation is of significance for the potential treatment of Alzheimer's disease. We have herein conjugated heptapeptide Ac-LVFFARK-NH2 (LK7) to beta-cyclodextrin (betaCyD) and studied the inhibitory effect of the LK7-betaCyD conjugate on Abeta aggregation. The conjugation significantly improved the peptide solubility and suppressed the self assembly propensity. This led to 30% increase of the binding affinity of LK7 for Abeta in the conjugate due to increased hydrophobic interactions. Thus, LK7 betaCyD suppressed the conformational transition of Abeta and showed stronger inhibitory effect on Abeta fibrillation than LK7. Thus, LK7-betaCyD exhibited protective effect on Abeta40-induced cytotoxicity, and the cells completely survived at 10 molar excess of LK7-betaCyD (from 67% to 100%). By contrast, LK7 showed only a moderate inhibition on Abeta fibrillation, and could not inhibit the amyloid cytotoxicity. The research proved that conjugation of hydrophobic peptide to betaCyD was promising to increase its inhibition potency against Abeta aggregation. PMID- 29453053 TI - Ultrasound molecular imaging of acute cardiac transplantation rejection using nanobubbles targeted to T lymphocytes. AB - Clinical surveillance of acute heart transplantation rejection requires repeated invasive endomyocardial biopsies and noninvasive diagnostic techniques are desperately needed. It is acknowledged that T lymphocyte infiltration is the central process of acute rejection. We hypothesized that ultrasound molecular imaging with T lymphocyte-targeted nanobubbles could be used to detect acute rejection in heart transplantation. In this study, nanobubbles bearing anti-CD3 antibody (NBCD3) or isotype antibody (NBcon) were prepared and characterized. There was significant adhesion of NBCD3 to T lymphocytes compared with NBconin vitro. The signal intensity of the adherent NBCD3 was significantly higher than that of the NBcon in allograft rats, but not significantly different in isograft rats. Furthermore, the signal intensity of NBCD3 in allograft rats was significantly higher than that in isograft rats, indicating more T lymphocyte infiltration in allograft rats compared with isograft rats. These results were further confirmed by immunohistochemistry examination, and the signal intensity of NBCD3 was positively correlated with the number of T lymphocytes in allograft rats. In summary, ultrasound molecular imaging with T lymphocyte-targeted nanobubbles can detect T lymphocyte infiltration in acute rejection and could be used as a noninvasive method in acute rejection detection after cardiac transplantation. PMID- 29453054 TI - Determining the number of contributors to DNA mixtures in the low-template regime: Exploring the impacts of sampling and detection effects. AB - The interpretation of DNA evidence may rely upon the assumption that the forensic short tandem repeat (STR) profile is composed of multiple genotypes, or partial genotypes, originating from n contributors. In cases where the number of contributors (NOC) is in dispute, it may be justifiable to compute likelihood ratios that utilize different NOC parameters in the numerator and denominator, or present different likelihoods separately. Therefore, in this work, we evaluate the impact of allele dropout on estimating the NOC for simulated mixtures with up to six contributors in the presence or absence of a major contributor. These simulations demonstrate that in the presence of dropout, or with the application of an analytical threshold (AT), estimating the NOC using counting methods was unreliable for mixtures containing one or more minor contributors present at low levels. The number of misidentifications was only slightly reduced when we expand the number of STR loci from 16 to 21. In many of the simulations tested herein, the minimum and actual NOC differed by more than two, suggesting that low template, high-order mixtures with allele counts fewer than six may be originating from as many as four-, five-, or six-persons. Thus, there is justification for the use of differing or multiple assumptions on the NOC when computing the weight of DNA evidence for low-template mixtures, particularly when the peak heights are in the vicinity of the signal threshold or allele counting methods are the mechanism by which the NOC is assessed. PMID- 29453055 TI - Enhanced electrosynthesis performance of Moorella thermoautotrophica by improving cell permeability. AB - Microbial electrosynthesis systems (MES) are promising devices in which microbes obtain electrons from electrodes to produce extracellular multicarbon compounds. This study investigates whether improvement in cell permeability can enhance electrosynthesis performance of Gram-positive Moorella thermoautotrophica in MES. Results showed that when <=30mg/L penicillin was added, the cell permeability was doubled, and the electron uptake per biomass (including both cathode-associated biomass and suspended biomass) was 1.84 times that of the control, while formate and acetate production rates per biomass were 1.96 and 2.23 times those of the control, respectively. Enhanced cell permeability caused higher redox activities of outmost cytochrome C and increased release of redox electron shuttles, both of which were beneficial to extracellular electron uptake. Coulombic efficiencies increased from 73%+/-3% to 88%+/-3% with better cell permeability, demonstrating that higher proportion of electrical energy recovered in the chemical-production reaction. This research demonstrates that making a moderate decrease in peptidoglycan of cell walls to improve cell permeability can enhance electron uptakes and chemical production rates of Gram-positive microbes in MES, which would serve as a base for the future genetic modification study of superior electrosynthesis strains. PMID- 29453056 TI - Biological properties of Beet soil-borne mosaic virus and Beet necrotic yellow vein virus cDNA clones produced by isothermal in vitro recombination: Insights for reassortant appearance. AB - Two members of the Benyviridae family and genus Benyvirus, Beet soil-borne mosaic virus (BSBMV) and Beet necrotic yellow vein virus (BNYVV), possess identical genome organization, host range and high sequence similarity; they infect Beta vulgaris with variable symptom expression. In the US, mixed infections are described with limited information about viral interactions. Vectors suitable for agroinoculation of all genome components of both viruses were constructed by isothermal in vitro recombination. All 35S promoter-driven cDNA clones allowed production of recombinant viruses competent for Nicotiana benthamiana and Beta macrocarpa systemic infection and Polymyxa betae transmission and were compared to available BNYVV B-type clone. BNYVV and BSBMV RNA1 + 2 reassortants were viable and spread long-distance in N. benthamiana with symptoms dependent on the BNYVV type. Small genomic RNAs were exchangeable and systemically infected B. macrocarpa. These infectious clones represent a powerful tool for the identification of specific molecular host-pathogen determinants. PMID- 29453057 TI - Mammarenaviruses deleted from their Z gene are replicative and produce an infectious progeny in BHK-21 cells. AB - Mammarenaviruses bud out of infected cells via the recruitment of the endosomal sorting complex required for transport through late domain motifs localized into their Z protein. Here, we demonstrated that mammarenaviruses lacking this protein can be rescued and are replicative, despite a 3-log reduction in virion production, in BHK-21 cells, but not in five other cell lines. Mutations of putative late domain motifs identified into the viral nucleoprotein resulted in the almost complete abolition of infectious virion production by Z-deleted mammarenaviruses. This result strongly suggested that the nucleoprotein may compensate for the deletion of Z. These observations were primarily obtained using the Lymphocytic choriomeningitis virus, and further confirmed using the Old World Lassa and New World Machupo viruses, responsible of human hemorrhagic fevers. Z-deleted viruses should prove very useful tools to investigate the biology of Mammarenaviruses. PMID- 29453058 TI - Antigenic and genetic evolution of contemporary swine H1 influenza viruses in the United States. AB - Several lineages of influenza A viruses (IAV) currently circulate in North American pigs. Genetic diversity is further increased by transmission of IAV between swine and humans and subsequent evolution. Here, we characterized the genetic and antigenic evolution of contemporary swine H1N1 and H1N2 viruses representing clusters H1-alpha (1A.1), H1-beta (1A.2), H1pdm (1A.3.3.2), H1-gamma (1A.3.3.3), H1-delta1 (1B.2.2), and H1-delta2 (1B.2.1) currently circulating in pigs in the United States. The delta1-viruses diversified into two new genetic clades, H1-delta1a (1B.2.2.1) and H1-delta1b (1B.2.2.2), which were also antigenically distinct from the earlier H1-delta1-viruses. Further characterization revealed that a few key amino acid changes were associated with antigenic divergence in these groups. The continued genetic and antigenic evolution of contemporary H1 viruses might lead to loss of vaccine cross protection that could lead to significant economic impact to the swine industry, and represents a challenge to public health initiatives that attempt to minimize swine-to-human IAV transmission. PMID- 29453059 TI - Lessons learned from research and surveillance directed at highly pathogenic influenza A viruses in wild birds inhabiting North America. AB - Following detections of highly pathogenic (HP) influenza A viruses (IAVs) in wild birds inhabiting East Asia after the turn of the millennium, the intensity of sampling of wild birds for IAVs increased throughout much of North America. The objectives for many research and surveillance efforts were directed towards detecting Eurasian origin HP IAVs and understanding the potential of such viruses to be maintained and dispersed by wild birds. In this review, we highlight five important lessons learned from research and surveillance directed at HP IAVs in wild birds inhabiting North America: (1) Wild birds may disperse IAVs between North America and adjacent regions via migration, (2) HP IAVs can be introduced to wild birds in North America, (3) HP IAVs may cross the wild bird-poultry interface in North America, (4) The probability of encountering and detecting a specific virus may be low, and (5) Population immunity of wild birds may influence HP IAV outbreaks in North America. We review empirical support derived from research and surveillance efforts for each lesson learned and, furthermore, identify implications for future surveillance efforts, biosecurity, and population health. We conclude our review by identifying five additional areas in which we think future mechanistic research relative to IAVs in wild birds in North America are likely to lead to other important lessons learned in the years ahead. PMID- 29453060 TI - Effect of selenium on Penaeus monodon and Perna viridis: Enzyme activities and histopathological responses. AB - The study was carried out to evaluate enzyme activities and histopathological changes due to the effect of acute and chronic definitive toxicity of selenium (Se) on the post larvae (PL) of giant tiger shrimp (Penaeus monodon), and green mussel (Perna viridis). The 96-h Median Lethal concentration (LC50) for the PL of shrimp was 3.36 mg L-1 and the chronic value for the long-term survival endpoint in a 21-d exposure was 0.10 mg L-1. The green mussel 96-h LC50 was 28.41 mg L-1 and the chronic value for the long-term survival endpoint in a 30-d exposure was 3.06 mg L-1. Native polyacrylamide gel electrophoresis revealed altered diverse isoforms of esterase, superoxide dismutase and malate dehydrogenase activities in the PL of shrimp and green mussel exposed to sublethal concentration of Se. Cellular anomalies such as deformation and fusion of corneal cells, detachment of corneal cells from cornea facet and increased space between ommatidia were observed in the compound eye of PL of shrimp exposed to Se for 21-d. Shrinkage and clumping of mucous gland, degenerative changes in phenol gland, and ciliated epithelium were observed in the foot of green mussel exposed to Se for 30-d. This study shows that cellular anomalies in the compound eye of PL of P. monodon and foot tissues of P. viridis described would affect the vision of shrimp and byssus thread formation in green mussel.

AB - This study presents the effect of aqueous uranium speciation (U-hydroxides and U hydroxo-carbonates) on the interaction of this radionuclide with the cells of the yeast Rhodotorula mucigilanosa BII-R8. This strain was isolated from Spanish bentonites considered as reference materials for the engineered barrier components of the future deep geological repository of radioactive waste. X-ray absorption and infrared spectroscopy showed that the aqueous uranium speciation has no effect on the uranium binding process by this yeast strain. The cells bind mobile uranium species (U-hydroxides and U-hydroxo-carbonates) from solution via a time-dependent process initiated by the adsorption of uranium species to carboxyl groups. This leads to the subsequent involvement of organic phosphate groups forming uranium complexes with a local coordination similar to that of the uranyl mineral phase meta-autunite. Scanning transmission electron microscopy with high angle annular dark field analysis showed uranium accumulations at the cell surface associated with phosphorus containing ligands. Moreover, the effect of uranium mobile species on the cell viability and metabolic activity was examined by means of flow cytometry techniques, revealing that the cell metabolism is more affected by higher concentrations of uranium than the cell viability. The results obtained in this work provide new insights on the interaction of uranium with bentonite natural yeast from genus Rhodotorula under deep geological repository relevant conditions.

AB - In this research, Ganzhou Chinese Cabbage (Brassica rapa pekinensis), Native Purple Garlic (Allium sativum L) and Leping Radish (Raphanus sativus L) widely planted and distributed along the Le'an River were chosen in the present study. Soil physical-chemical properties, nutrients contents as well as heavy metals elements accumulated in both soils and vegetables collected from 24 sites were analyzed by lab analysis combined with statistical method which was also used for calculation of contamination factor, pollution indexes and hazardous index. Heavy metals accumulation in soils were revealed with higher level, and copper and cadmium exceeded the background values by 8.82 and 16.73 times on average, which were also significantly related with the distribution of nonferrous metal processing enterprises. Heavy metal elements accumulated in vegetables were fully consistent with the finding of pollution characteristics in soils. Peroxidase biomarkers in vegetables, including superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), reduced glutathione (GSH) and lipoperoxidation (as TBARS), as well as integrated biomarker responses (IBR) were determined to give a reliable response after exposing of contaminants. Heavy metals accumulation ability and biomarker responses for three vegetables were usually determined in the following decrease trend: Ganzhou Chinese Cabbage > Native Purple Garlic > Leping Radish. Compared with peroxidase biomarkers activities or contents of control site, all the measured biomarkers in polluted sites showed significantly responses, indicating potential relationship between pollutants stresses and biomarker responses. This study also revealed that the IBR values were coordinated well with the pollutants concentrations. PMID- 29453063 TI - 1H NMR-based metabolomics reveals interactive effects between the carrier solvent methanol and a pharmaceutical mixture in an amphibian developmental bioassay with Limnodynastes peronii. AB - Organic carrier solvents are used in aquatic toxicity testing to improve chemical solubility and facilitate the exploration of dose-response relationships. Both water- and solvent-control groups are normally included in these scenarios to ensure that the solvent itself has no effect on the test organism, but this fails to consider possible interactive effects between carrier solvents and contaminants of interest. We explored this topic by exposing Limnodynastes peronii tadpoles to a mixture of common water-soluble pharmaceuticals (diclofenac, metformin and valproic acid) in the presence and absence of the carrier solvent methanol, according to standard developmental bioassay methodology. Nuclear Magnetic Resonance (NMR) spectroscopy was applied as a platform for untargeted metabolomics, to compare broad sub-lethal hepatotoxicity in solvent- and solvent-free exposure scenarios. Considerable interactive effects were identified between the pharmaceutical mixture and a typical dose of methanol (0.003%). Specifically, pronounced differences were observed between the solvent- and solvent-free exposure groups for leucine, acetate, glutamine, citrate, glycogen, tyrosine, arginine, purine nucleotides and an unidentified metabolite at 6.53 ppm. Various other metabolites exhibited similar disparity related to the use of carrier solvent, but the interactions were non-significant. These results raise important questions about the use of carrier solvents for chemical exposures in aquatic ecotoxicology, and particularly for studies interested in sub-lethal mechanistic information and/or biomarker discovery. PMID- 29453064 TI - Levels, sources, and potential human health risks of PCNs, PCDD/Fs, and PCBs in an industrial area of Shandong Province, China. AB - Polychlorinated naphthalenes (PCNs), polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), and polychlorinated biphenyls (PCBs) are of public concern worldwide because of their persistence and toxicity. To address the human health risks of these pollutants and identify possible sources, soil samples were collected from an industrial area and surrounding residential area in Shandong Province, China. The PCN, PCDD/F, and PCB levels in these samples were determined. Extremely high concentrations of PCNs were detected in two soil samples, and their congener distributions were similar to those of a PCN industrial technical product. The levels of combustion-related PCNs and PCDD/Fs were high in samples collected near a secondary copper smelter. The distribution of total PCB concentrations was similar to that of PCNs. Both historical residues from industrial technical products and emissions from the secondary copper smelter were likely sources of PCNs and PCBs, whereas emissions from the smelter were the main source of PCDD/Fs. A soil sample from near the smelter had a high SigmaTEQ concentration (PCDD/Fs + PCBs + PCNs = 18.33 pg TEQ/g) and carcinogenic risk (0.85 * 10-6) to workers. For all the other samples, the levels of PCDD/Fs, PCBs and PCNs exhibited low carcinogenic and noncarcinogenic risks to workers and residents.

AB - Puccinellia distans, common alkali grass, is found throughout the world and can survive in soils with boron concentrations that are lethal for other plant species. Indeed, P. distans accumulates very high levels of this element. Despite these interesting features, very little research has been performed to elucidate the boron tolerance mechanism in this species. In this study, P. distans samples were treated for three weeks with normal (0.5 mg L-1) and elevated (500 mg L-1) boron levels in hydroponic solution. Expressed sequence tags (ESTs) derived from shoot tissue were analyzed by RNA sequencing to identify genes up and down regulated under boron stress. In this way, 3312 differentially expressed transcripts were detected, 67.7% of which were up-regulated and 32.3% of which were down-regulated in boron-treated plants. To partially confirm the RNA sequencing results, 32 randomly selected transcripts were analyzed for their expression levels in boron-treated plants. The results agreed with the expected direction of change (up or down-regulation). A total of 1652 transcripts had homologs in A. thaliana and/or O. sativa and mapped to 1107 different proteins. Functional annotation of these proteins indicated that the boron tolerance and hyperaccumulation mechanisms of P. distans involve many transcriptomic changes including: alterations in the malate pathway, changes in cell wall components that may allow sequestration of excess boron without toxic effects, and increased expression of at least one putative boron transporter and two putative aquaporins. Elucidation of the boron accumulation mechanism is important in developing approaches for bioremediation of boron contaminated soils.

AB - Biochar improves soil fertility and promotes long-term terrestrial carbon sequestration. However, biochar seems not to be stable enough due to physical, chemical and biological reactions. In this study, a novel, stable, and magnesium (Mg)-impregnated biochar was prepared from cow dung and applied to decrease P leaching from soil. XPS, FTIR, XRD, SEM and EDS were used to evaluate the effect of modification and phosphorus(P) sorption on the oxidation resistance of biochar. The results showed that the oxidation resistance of the Mg-impregnated biochar was improved by the formation of MgO on its surface. The soil column experiment indicated that the Mg-impregnated -biochar decreased P loss from leaching by 89.25%. In addition, the available P content of the soil surface layer under Mg-impregnated biochar treatment increased by 3.5-fold relative to that under the control treatment. P sorption also enhanced the oxidation resistance of biochar. The relative contents of CO, CO, and COOH on the surface of P-laden biochar was 20.97% and was lower than those on the surface of biochar without P sorption (33.15%). Oxidation resistance was enhanced by the formation of new MgP crystals, which prevented the oxidation of CC, CC, and CH into CO, CO, and COOH, respectively, by acting as a physical barrier between the biochar surface and oxygen. The results of XRD, SEM and EDS provided evidence for the formation of MgP crystals. Overall, results indicated that the Mg-impregnated biochar can reduce P leaching loss from soil and has enhanced stability. PMID- 29453067 TI - Applying no-depletion equilibrium sampling and full-depletion bioaccessibility extraction to 35 historically polycyclic aromatic hydrocarbon contaminated soils. AB - Assessing the bioaccessibility of organic pollutants in contaminated soils is considered a complement to measurements of total concentrations in risk assessment and legislation. Consequently, methods for its quantification require validation with historically contaminated soils. In this study, 35 such soils were obtained from various locations in Switzerland and Cuba. They were exposed to different pollution sources (e.g., pyrogenic and petrogenic) at various distance (i.e., urban to rural) and were subject to different land use (e.g., urban gardening and forest). Passive equilibrium sampling with polyoxymethylene was used to determine freely dissolved concentrations (Cfree) of polycyclic aromatic hydrocarbons (PAHs), while sorptive bioaccessibility extraction (SBE) with silicone rods was used to determine the bioaccessible PAH concentrations (Cbioacc) of these soils. The organic carbon partition coefficients of the soils were highest for skeet soils, followed by traffic, urban garden and rural soils. Lowest values were obtained from soil exposed to petrogenic sources. Applicability of SBE to quantify Cbioacc was restricted by silicone rod sorption capacity, as expressed quantitatively by the Sorption Capacity Ratio (SCR); particularly for soils with very high KD. The source of contamination determined bioaccessible fractions (fbioacc). The smallest fbioacc were obtained with skeet soils (15%), followed by the pyrogenically influenced soils, rural soils, and finally, the petrogenically contaminated soil (71%). In conclusion, we present the potential and limitations of the SBE method to quantify bioaccessibility in real soils. These results can be used for additional development of this and similar bioaccessibility methods to guarantee sufficient sorption capacity to obtain reliable results. PMID- 29453068 TI - Effect of selenium-enriched organic material amendment on selenium fraction transformation and bioavailability in soil. AB - To exploit the plant byproducts from selenium (Se) biofortification and reduce environmental risk of inorganic Se fertilizer, pot experiment was conducted in this study. The effects of Se-enriched wheat (Triticum aestivum L.) straw (WS + Se) and pak choi (Brassica chinensis L.) (P + Se) amendment on organo-selenium speciation transformation in soil and its bioavailability was evaluated by pak choi uptake. The Se contents of the cultivated pak choi in treatments amended with the same amount of Se-enriched wheat straw and pak choi were 1.7 and 9.7 times in the shoots and 2.3 and 6.3 times in the roots compared with control treatment. Soil respiration rate was significantly increased after all organic material amendment in soil (p < 0.05), which accelerated the mineralization of organic materials and thus resulted in soluble Se (SOL-Se), exchangeable Se (EX Se), and fulvic acid-bound Se (FA-Se) fraction increasing by 25.2-29.2%, 9-13.8%, and 4.92-8.28%, respectively. In addition, both Pearson correlation and cluster analysis showed that EX-Se and FA-Se were better indicators for soil Se availability in organic material amendment soils. The Marquardt-Levenberg Model well described the dynamic kinetics of FA-Se content after Se-enriched organic material amendment in soil mainly because of the mineralization of organic carbon and organo-selenium. The utilization of Se in P + Se treatment was significantly higher than those in WS + Se treatment because of the different mineralization rates and the amount of FA-Se in soil. Se-enriched organic materials amendment can not only increase the availability of selenium in soil but also avoid the waste of valuable Se source. PMID- 29453069 TI - Combined effect of copper and hydrodynamic conditions on Myriophyllum alterniflorum biomarkers. AB - The aim of this study is to determine the combined effect of copper and hydrodynamic conditions on the response of certain biomarkers of an aquatic macrophyte, namely Myriophyllum alterniflorum. Watermilfoil biomarkers are monitored in a synthetic medium enriched or not with copper (100 MUg.L-1) for 21 days in aquarium systems (150 L), under three hydrodynamic conditions: laminar, turbulent, and calm. The studied biomarkers are: respiratory and photosynthetic activities; concentrations of chlorophyll a, b and carotenoids; osmotic potential; hydrogen peroxide content; and growth. In addition, Cu contents in water and in Myriophyllum alterniflorum (roots and shoots) are investigated. The hydrodynamic conditions only affect watermilfoil morphology. Copper accumulates less in turbulent zones; moreover, it is more likely to accumulate in shoots than in roots, except within the calm zone. Cu leads to: i) a significant increase in H2O2 content, ii) a decrease in root growth, pigment content, osmotic potential, photosynthesis and respiration rates, and iii) an inhibition of shoot branching. Differential effects are also observed between younger and older parts, thus indicating the benefit of considering these two plant parts separately in water quality biomonitoring. PMID- 29453070 TI - Magnetic Zr-MOFs nanocomposites for rapid removal of heavy metal ions and dyes from water. AB - Amino-decorated Zr-based magnetic Metal-Organic Frameworks composites (Zr-MFCs) were prepared by a facile and efficient strategy. The nano-sized Fe3O4@SiO2 core (about 15 nm) was coated with a shell of Zr-MOFs (about 5 nm) by means of in-situ growth. And, Fe3O4@SiO2@UiO-66 and its amino derivatives (Fe3O4@SiO2@UiO-66-NH2 and Fe3O4@SiO2@UiO-66-Urea) were successfully prepared by using different precursors. The obtained Zr-MFCs were demonstrated to be efficient adsorbents for metal ions/organic dyes removal from aqueous solution, with high adsorption capacity and fast adsorption kinetics. It was found that the amine-decorated MFCs were highly efficient for metal ions/dyes removal compared to raw MFC-O. Among them, MFC-N exhibited the highest capacity for Pb2+ (102 mg g-1) and methylene blue (128 mg g-1), while MFC-O exhibited the highest capacity for methyl orange (219 mg g-1). Moreover, anionic and cationic dyes could be selectively separated and removed from the mixed solution just by adjusting the solution pH with Zr MFCs as the adsorbents. And these Zr-MFCs materials can be easily regenerated by desorbing metal ions/organic dyes from the sorbents with appropriate eluents, and the adsorption capacity can be remained unchanged after 6 recycles. The obtained results demonstrated the great application potential of the prepared MFCs as fascinating adsorbents for water treatment. PMID- 29453071 TI - Degradation of dye Procion Red MX-5B by electrolytic and electro-irradiated technologies using diamond electrodes. AB - This work focuses on the treatment of synthetic wastewater polluted with dye Procion Red MX-5B by different Electrochemical Advanced Oxidation Processes (EAOP) based on diamond anodes. The influence of the current density and the supporting electrolyte has been studied on dye removal and total mineralization of the organic matter. Results show that electrolysis with diamond electrodes is a suitable technology for an efficient degradation of dye. Nonetheless, the process efficiency increases when using chloride as supporting electrolyte because of the electrochemical generation of hypochlorite in wastewater which significantly contribute to dye removal. On the contrary, the total mineralization of the organic matter is more efficient in sulfate media. In this case, large amounts of peroxodisulfate are electrogenerated, favoring the complete removal of total organic carbon (TOC). On the other hand, lower current densities (10 mA cm-2) lead to a more efficient removal of both dye and TOC due to the mass transfer limitations of the technology. Finally, the coupling of UV light irradiation or ultrasound to electrolysis significantly improves the process performance, being photoelectrolysis the most efficient technology for the treatment of wastewater polluted with Procion Red MX-5B. This fact is due to the potential production of free chlorine or sulfate radicals that takes place by the activation of the electrogenerated oxidants. These species are more reactive than oxidants and, therefore, they quickly attack the organic matter present in wastewater. PMID- 29453072 TI - Selection criteria for oxidation method in total organic carbon measurement. AB - During the measurement of total organic carbon (TOC), dissolved organic carbon is converted into CO2 by using high temperature combustion (HTC) or wet chemical oxidation (WCO). However, the criteria for selecting the oxidation methods are not clear. In this study, the chemical structures of organic material were considered as a key factor to select the oxidation method used. Most non degradable organic compounds showed a similar oxidation efficiency in both methods, including natural organic compounds, dyes, and pharmaceuticals, and thus both methods are appropriate to measure TOC in waters containing these compounds. However, only a fraction of the carbon in the halogenated compounds (perfluorooctanoic acid and trifluoroacetic acid) were oxidized using WCO, resulting in measured TOC values that are considerably lower than those determined by HTC. This result is likely due to the electronegativity of halogen elements which inhibits the approach of electron-rich sulfate radicals in the WCO, and the higher bond strength of carbon-halogen pairs as compared to carbon hydrogen bonds, which results in a lower degree of oxidation of the compounds. Our results indicate that WCO could be used to oxidize most organic compounds, but may not be appropriate to quantify TOC in organic carbon pools that contain certain halogenated compounds. PMID- 29453073 TI - Stabilization of lead (Pb) and zinc (Zn) in contaminated rice paddy soil using starfish: A preliminary study. AB - Lead (Pb) and zinc (Zn) contaminated rice paddy soil was stabilized using natural (NSF) and calcined starfish (CSF). Contaminated soil was treated with NSF in the range of 0-10 wt% and CSF in the range of 0-5 wt% and cured for 28 days. Toxicity characteristic leaching procedure (TCLP) test was used to evaluate effectiveness of starfish treatment. Scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDX) analyses were conducted to investigate the mechanism responsible for effective immobilization of Pb and Zn. Experimental results suggest that NSF and CSF treatments effectively immobilize Pb and Zn in treated rice paddy soil. TCLP levels for Pb and Zn were reduced with increasing NSF and CSF dosage. Comparison of the two treatment methods reveals that CSF treatment is more effective than NSF treatment. Leachability of the two metals is reduced approximately 58% for Pb and 51% for Zn, upon 10 wt% NSF treatment. More pronounced leachability reductions, 93% for Pb and 76% for Zn, are achieved upon treatment with 5 wt% CSF. Sequential extraction results reveal that NSF and CSF treatments of contaminated soil generated decrease in exchangeable/weak acid Pb and Zn soluble fractions, and increase of residual Pb and Zn fractions. Results for the SEM-EDX sample treated with 5 wt% CSF indicate that effective Pb and Zn immobilization is most probably associated with calcium silicate hydrates (CSHs) and calcium aluminum hydrates (CAHs). PMID- 29453074 TI - Use of prostaglandin F2alpha as ovulatory stimulus for synchronizing dairy cattle. AB - The aim of this study was to evaluate if prostaglandin F2alpha (PGF) can be used to induce ovulation in a GnRH-progesterone based protocol. In Experiment 1 crossbred dairy cows (n=32) were synchronized with a progesterone-GnRH based protocol for seven days, where the luteolytic dose of 150MUg PGF was given 24h prior progesterone device removal (CIDR). On Day 8 cows were separated into two groups to receive: 1) 2mL of Saline (Control Group, n=15) or 2) 150MUg of PGF (PGF Group, n=17). Ovulation rate was higher in the PGF than Control group (100% vs 53.3%, P=0.001, Odds ratio=30.88). The percentage of cows that ovulated synchronously tended to be higher in the PGF than Control group (P=0.1, Odds ratio=9.6). Experiment 2 was performed in a cross-over (3*3) design. Crossbred dairy cows (n=25) received a CIDR for seven days and GnRH on Day 0. Seven days later 150MUg of PGF was given and the progesterone device was removed, and 24h later cows were distributed into three groups to receive: 1) 2mL of Saline (Control Group, n=25), 2) 150MUg of PGF (PGF Group, n=25) or 3) 1mg of ECP (ECP Group, n=23). Diameter of ovulatory follicle was larger in the PGF and Control than ECP Group (P=0.002, Effect size>4.0). Synchronized ovulation rate (between 72 and 96h after CIDR removal) tended to be higher in PGF group in Control group (P=0.1, Odds ratio=0.35). Results suggest that PGF is equally efficient to ECP to induce synchronized ovulation in dairy cows subjected to progesterone-GnRH based protocols. PMID- 29453075 TI - Pharmacokinetic variability of valproate during pregnancy - Implications for the use of therapeutic drug monitoring. AB - BACKGROUND AND PURPOSE: Use of valproate (VPA) in women of childbearing age is restricted due to dose-dependent risk of teratogenicity. The purpose of this study was to characterise pharmacokinetic variability of VPA in pregnancy, and discuss use of therapeutic drug monitoring (TDM) as guidance to exposure in women. METHOD: Measurements of trough total and unbound VPA concentrations before, during and after pregnancy, at assumed steady-state were collected from the TDM-database (2006-2016) at the National Center for Epilepsy in Norway. Additional clinical data were obtained from the Oppland county Perinatal Database (1994-2011). RESULTS: Data from 51 pregnancies in 33 women aged 19-40 years were included. Each woman underwent 1-4 pregnancies, and 1-7 measurements per pregnancy were performed. The variability in total concentration/dose (C/D) ratios between women was 13-fold, and intra-patient variability extensive. Total C/D-ratios were reduced by 46% from before pregnancy to third trimester (0.48 0.29 MUmol/L/mg). Unbound concentrations of VPA were only requested in 10% of the pregnancies. Repeated measurements from two pregnancies in one women revealed increased unbound concentration of VPA during pregnancy. There were 19 with idiopathic generalized epilepsy and two focal based on clinical data from 21 women and 38 pregnancies; 1 major congenital malformation was noted. CONCLUSION: There is pronounced pharmacokinetic variability of VPA during pregnancy. Unbound concentrations are rarely requested. TDM should be used by measurements of both total and unbound concentrations since total concentrations may be misleading for efficacy and fetal exposure of VPA.

AB - Herein we report the synthesis of two series of 4-phenylphthalazin-1-ones 11a-i and 4- benzylphthalazin-1-ones 16a-h as anti-lung adenocarcinoma agents with potential inhibitory activity against PARP-1. All the newly synthesized phthalazinones were evaluated for their anti-proliferative activity against A549 lung carcinoma cell line. Phthalazinones 11c-i and 16b, c showed significant cytotoxic activity against A549 cells at different concentrations (0.1, 1 and 10 MUM) for two time intervals (24 h and 48 h). These nine phthalazinones were further examined for their inhibitory activity towards PARP-1. Compound 11c emerged as the most potent PARP-1 inhibitor with IC50 value of 97 nM, compared to that of Olaparib (IC50 = 139 nM). Furthermore, all these nine phthalazinones passed the filters of Lipinski and Veber rules, and predicted to have good pharmacokinetics properties in a theoretical kinetic study. On the other hand, western blotting in A549 cells revealed the enhanced expression of the cleaved PARP-1, alongside, with the reduced expression of pro-caspase-3 and phosphorylated AKT. In addition, ELISA assay confirmed the up-regulation of active caspase-3 and caspase-9 levels compared to the control, suggesting the activation of the apoptotic machinery in the A549 cells. Finally, molecular docking of 11c into PARP-1 active site (PDB: 5WRZ) was performed to explore the probable binding mode.

The present work has performed the investigation of bioactive chemical substances from the roots of E. ebracteolata. Using various chromatographic techniques, 15 compounds were obtained from the roots of E. ebracteolata. On the basis of widely spectroscopic data analyses, the isolated compounds were determined to be diterpenoids, including rosane derivatives (1-12), isopimarane (13), abietane (14), and lathyrane (15), among which compounds 1-4, and 9 were undescribed previously. The inhibitory effects of isolated diterpenoids against Mycobacterium tuberculosis were evaluated using an Alamar blue cell viability assay. And two rosane-type diterpenoids 3 and 8 displayed moderate inhibitory effects on with the MIC values of 18 MUg/mL and 25 MUg/mL, respectively. For the potential inhibitor 3, the inhibitory effect against the target enzyme GlmU was evaluated, which displayed a moderate inhibitory effect with the IC50 12.5 MUg/mL. Therefore, the diterpenoids from the roots of E. ebracteolata displayed anti tuberculosis effects, which would be pay more attentions for the anti tuberculosis agents.

AB - In this paper, effective energy of pulsed X-Ray emitted from a Mather-type plasma focus device in stored energy of 2.5 kJ with six different anode's insert materials was measured using radiographic method with attenuation filters. Since intensity and energy of X-ray beam were considerably changed with changing the insert material, the method was improved by using different filters simultaneously in all the experiments and selection of the best filter in each experiment according to the appropriate criteria. Effective energy of pulsed X ray beam was measured 16, 28, 50, 51, 34 and 44 keV when aluminum, copper, zinc, tin, tungsten and lead were used as insert materials, and aluminum, copper, silver, silver, copper and lead were used as filters, respectively.

AB - Dyslexia (D) is a neurodevelopmental reading disorder characterized by phonological and orthographic deficits. Before phonological decoding, reading requires a specialized orthographic system for parallel letter processing that assigns letter identities to different spatial locations. The magnocellular dorsal (MD) stream rapidly process the spatial location of visual stimuli controlling visuo-spatial attention. To investigate the visuo-spatial attention efficiency during orthographic processing, inhibition of return (IOR) was measured in adults with and without D in a lexical decision task. IOR is the delay in responding to stimuli displayed in a cued location after a long cue target interval. Only adults with D did not showed IOR effect during letter string recognition, despite the typical left-hemisphere specialization for word identification. A specific deficit in coherent-dot-motion perception confirmed an MD-stream disorder in adults with D. Our results suggest that adults with D might develop an efficient visual word form area, but a dorsal-attentional dysfunction impairs their reading fluency. PMID- 29453082 TI - Potential roles for transposable elements in creating imprinted expression. AB - Changes in gene expression can have profound effects on phenotype. Nature has provided many complex patterns of gene regulation such as imprinting. Imprinted genes exhibit differences in the expression of the maternal and paternal alleles, even though they reside in the same nucleus with access to the same trans-acting factors. Significant attention has been focused on the potential reasons that imprinted expression could be beneficial and stabilized by selection. However, less attention has focused on understanding how imprinted expression might arise or decay. We discuss the evidence for frequent turnover of imprinted expression based on evolutionary analyses in plants and the potential role for transposable elements (TEs) in creating imprinted expression patterns. PMID- 29453083 TI - Nonuniform sampling by quantiles. AB - A flexible strategy for choosing samples nonuniformly from a Nyquist grid using the concept of statistical quantiles is presented for broad classes of NMR experimentation. Quantile-directed scheduling is intuitive and flexible for any weighting function, promotes reproducibility and seed independence, and is generalizable to multiple dimensions. In brief, weighting functions are divided into regions of equal probability, which define the samples to be acquired. Quantile scheduling therefore achieves close adherence to a probability distribution function, thereby minimizing gaps for any given degree of subsampling of the Nyquist grid. A characteristic of quantile scheduling is that one-dimensional, weighted NUS schedules are deterministic, however higher dimensional schedules are similar within a user-specified jittering parameter. To develop unweighted sampling, we investigated the minimum jitter needed to disrupt subharmonic tracts, and show that this criterion can be met in many cases by jittering within 25-50% of the subharmonic gap. For nD-NUS, three supplemental components to choosing samples by quantiles are proposed in this work: (i) forcing the corner samples to ensure sampling to specified maximum values in indirect evolution times, (ii) providing an option to triangular backfill sampling schedules to promote dense/uniform tracts at the beginning of signal evolution periods, and (iii) providing an option to force the edges of nD-NUS schedules to be identical to the 1D quantiles. Quantile-directed scheduling meets the diverse needs of current NUS experimentation, but can also be used for future NUS implementations such as off-grid NUS and more. A computer program implementing these principles (a.k.a. QSched) in 1D- and 2D-NUS is available under the general public license.

AB - The aim of the current investigation was to develop solid lipid nanoparticles of olmesartan medoxomil using hot homogenization method to improve its oral bioavailability. Central composite design was applied to optimize the formulation variables; lipid X1 (Glyceryl monostearate) and surfactant X2 (Poloxamer: Tween 80). The particle sizes were in the nanometer range and spherical shaped for all prepared solid lipid nanoparticles formulations and the zeta potential absolute values were high, predicting good long-term stability. In vitro study of olmesartan loaded solid lipid nanoparticle exhibited controlled release profile for at least 24 h. The rate and extent of drug diffusion was studied using dialysis sac, rat's stomach and intestine tissues; study demonstrated that drug release from the solid lipid nanoparticles was significantly higher than drug suspension. In vivo pharmacokinetic study of olmesartan loaded solid lipid nanoparticles revealed higher Cmax of 1610 ng/mL, higher AUC of 15492.50 ng/mL and increased relative bioavailability by almost 2.3 folds compared to marketed formulation. These results clearly indicate that olmesartan loaded solid lipid nanoparticles are shown to have enhanced bioavailability and effective therapeutic result and thus would be an excellent way to treat hypertension. Hence, these solid lipid nanoparticles could represent as a great potential for a possible alternative to conventional oral formulation in the treatment of hypertension.

AB - In this study, a redox-sensitive glioma-targeting micelle system was designed to deliver curcumin (CUR) by conjugating it to hyaluronic acid (HA-s-s-CUR, HSC) via disulfide linkage. The effect of the molecular weight of HA on the physicochemical characteristics of HSC conjugates and their in vitro effects in glioma cells were also explored. These conjugates formed nano-scale micelles (209 926 nm) independently in aqueous solution. The micelles greatly increased the solubility of CUR and improved its stability, which is crucial for harnessing the therapeutic potential of this active molecule. The redox sensitivities of different HSC micelles were measured by using a dynamic light scattering method and in vitro release assay, which showed that the low (50 kDa) and medium molecular weight (200 kDa and 500 kD) HA-based conjugates were sensitive to GSH, whereas higher molecular weights (1000 kDa and 2000 kDa) did not show redox sensitivity. Increased cytotoxicity and uptake of low and medium molecular weight modified HSC conjugates by the glioma cells further confirmed that the sensitive micelles are more effective for intracellular drug delivery compared to the high molecular weight-modified HSC conjugates or the plain CUR. In summary, the molecular weight of HA affects the physicochemical attributes of HSC conjugates. Only HSC micelles made with HA molecules less than 500 kDa exhibit redox sensitivity.

AB - The major goal of cancer chemotherapy is to maximize the therapeutic efficacy of anticancer drugs, while minimizing their associated side effects. Celastrol (CST), which is extracted from the traditional Chinese medicinal plant Tripterygium wilfordii, has been reported to exhibit significant anticancer effects in various in vitro and in vivo cancer models. Nanoparticulate drug delivery systems could be employed to preserve and enhance the pharmacological effects of CST in cancer cells. Among these, mesoporous silica nanoparticles (MSNs) are one of the most promising drug delivery systems. MSNs possess the capability of passive accumulation within solid tumors, and could efficiently transport anticancer drugs to such tumors in a site-specific manner. In this study, PEGylated polyaminoacid-capped CST-loaded MSN (CMSN-PEG) showed controlled in vitro drug release behavior, and exhibited high in vitro cytotoxicity in different cancer cells. Compared to treatment with free CST, treatment with CMSN PEG resulted in the increased expression of the apoptosis protein HIF-1alpha and proteins corresponding to mitochondrial apoptosis pathway. Importantly, CMSN-PEG remarkably reduced tumor burden with no toxicity to healthy cells in the SCC7 tumor-bearing xenograft model. Our results clearly demonstrate a promising potential of CMSN-PEG for the treatment of solid tumors. PMID- 29453087 TI - Interleukin-6 is an independent predictor of progressive atherosclerosis in the carotid artery: The Tromso Study. AB - BACKGROUND AND AIMS: Novel biomarkers are linked to cardiovascular disease (CVD). The aim of the present study was to investigate the association between 28 blood biomarkers and the formation and progression of carotid plaque. METHODS: In a nested case control study with 703 participants from the population based Tromso Study, a large biomarker panel was measured in blood obtained at baseline. Carotid ultrasound was assessed both at baseline and at 6 years of follow-up. Four groups were defined: Group 1: no plaque at baseline or at follow-up (reference group); Group 2: novel plaque at follow-up; Group 3: stable plaque at follow-up; Group 4: progression of plaque at follow-up. By multinomial logistic regression analyses, we assessed the risk of being in the different plaque groups with regard to traditional cardiovascular risk factors and levels of biomarkers at baseline. RESULTS: Adjusted for traditional risk factors, interleukin-6 (IL-6) was an independent predictor of plaque progression (OR 1.44, 95% CI 1.12-1.85 per SD increase in IL-6 level). This result remained significant after inclusion of other novel biomarkers to the model, and when subjects with former CVD were excluded. Neopterin was protective of novel plaque formation (OR 0.73, 95% CI 0.57-0.93). Myeloperoxidase and Caspase-1 were independent predictors of plaque progression, but this effect disappeared when excluding subjects with former CVD. CONCLUSIONS: IL-6 is an independent predictor of plaque progression, suggesting that it may be a marker of progressive atherosclerosis in the general population and that its central role in CVD may be related to promotion of plaque growth. PMID- 29453088 TI - Serum matrix metalloproteinase-8, tissue inhibitor of metalloproteinase and myeloperoxidase in ischemic stroke. AB - BACKGROUND AND AIMS: Matrix metalloproteinase (MMP)-8 and myeloperoxidase (MPO) may contribute to cerebral damage in acute ischemic stroke. We tested the hypothesis that levels of MPO, MMP-8 and the ratio between MMP-8 and its regulator, tissue inhibitor of metalloproteinase (TIMP-1), are increased in acute ischemic stroke and its etiologic subgroups and they correlate with stroke severity. METHODS: In a cross-sectional case-control study, serum concentrations of MMP-8, MPO and TIMP-1 were assessed within 24 h after admission in 470 first ever ischemic stroke patients and 809 age- and sex-matched controls, randomly selected from the population. Odds ratios (OR) per decade of log transformed dependent variables were calculated and adjusted for age, sex and vascular risk factors. RESULTS: Levels of MMP-8 (OR 4.9; 95% CI 3.4-7.2), MMP-8/TIMP-1 ratio (3.0; 2.2-4.1) and MPO (6.6; 4.0-11.0) were independently associated with ischemic stroke. MMP-8 levels differed between etiologic stroke subgroups (p = 0.019, ANOVA), with higher levels in cardioembolic stroke and stroke due to large vessel disease, and lower levels in microangiopathic stroke. MMP-8, MMP-8/TIMP-1 ratio and MPO (p < 0.001) concentrations showed positive associations with stroke severity independent of stroke etiology. CONCLUSIONS: Concentrations of serum neutrophil markers are increased after ischemic stroke and associate with stroke severity and etiology. The value of these biomarkers in diagnostics and prognostics is worth being evaluated. PMID- 29453089 TI - Botanical essential oils and uses as mosquitocides and repellents against dengue. AB - Plants naturally produce bioactive compounds along with many secondary metabolites which serve as defensive chemical against herbivorers including insect pests. One group of these phytochemicals are the 'Essential Oils' (EO's), which possess an extensive range of biological activity especially insecticidal and insect repellents. This review provides a comprehensive viewpoint on potential modes of action of biosafety plant derived Essential Oils (EO's) along with their principal chemical derivatives against larvae and adult mosquito vectors of dengue virus. The development and use of Essential Oils (EO's) effectively applied in small rural communities provides an enormous potential for low cost effective management of insect vectors of human pathogens which cause disease. PMID- 29453090 TI - Evaluating effects of prenatal exposure to phthalate mixtures on birth weight: A comparison of three statistical approaches. AB - OBJECTIVES: We applied three statistical approaches for evaluating associations between prenatal urinary concentrations of a mixture of phthalate metabolites and birth weight. METHODS: We included 300 women who provided 732 urine samples during pregnancy and delivered a singleton infant. We measured urinary concentrations of metabolites of di(2-ethylhexyl)-phthalate, di-isobutyl-, di-n butyl-, butylbenzyl-, and diethyl phthalates. We applied 1) linear regressions; 2) classification methods [principal component analysis (PCA) and structural equation models (SEM)]; and 3) Bayesian kernel machine regression (BKMR), to evaluate associations between phthalate metabolite mixtures and birth weight adjusting for potential confounders. Data were presented as mean differences (95% CI) in birth weight (grams) as each phthalate increased from the 10th to the 90th percentile. RESULTS: When analyzing individual phthalate metabolites using linear regressions, each metabolite demonstrated a modest inverse association with birth weight [from -93 (-206, 21) to -49 (-164, 65)]. When simultaneously including all metabolites in a multivariable model, inflation of the estimates and standard errors were noted. PCA identified two principal components, both inversely associated with birth weight [-23 (-68, 22), -27 (-71, 17), respectively]. These inverse associations were confirmed when applying SEM. BKMR further identified that monoethyl and mono(2-ethylhexyl) phthalate and phthalate concentrations were linearly related to lower birth weight [-51(-164, 63) and -122 (-311, 67), respectively], and suggested no evidence of interaction between metabolites. CONCLUSIONS: While none of the methods produced significant results, we demonstrated the potential issues arising using linear regression models in the context of correlated exposures. Among the other selected approaches, classification techniques identified common sources of exposures with implications for interventions, while BKMR further identified specific contributions of individual metabolites. PMID- 29453091 TI - Identification of miRNAs and their targets in maize in response to Sugarcane mosaic virus infection. AB - MicroRNAs (miRNAs) are endogenous non-coding small RNAs that play essential regulatory roles in plant development and environmental stress responses. Maize (Zea mays L.) is a global economically important food and forage crop. To date, a number of maize miRNAs have been identified as being involved in plant development and stress responses. However, the miRNA-mediated gene regulatory networks responsive to virus infections in maize remain largely unknown. In this study, the profiles of small RNAs in buffer- and Sugarcane mosaic virus (SCMV) inoculated maize plants were obtained by high-throughput sequencing, respectively. A total of 154 known miRNAs and 213 novel miRNAs were profiled and most of the miRNAs identified were differentially expressed after SCMV infection. In addition, 70 targets of 13 known miRNAs and 3 targets of a novel miRNA were identified by degradome analysis. The results of Northern blotting and quantitative real-time PCR showed that the expression levels of the selected miRNAs and their targets were mostly influenced by SCMV infection at 12 days post inoculation, including up-regulation of miR168 and miR528, and down-regulation of miR159, miR397 and miR827. These results provide new insights into the regulatory networks of miRNAs and their targets in maize plants responsive to SCMV infection. PMID- 29453092 TI - Silicon induced Fe deficiency affects Fe, Mn, Cu and Zn distribution in rice (Oryza sativa L.) growth in calcareous conditions. AB - A protective effect by silicon in the amelioration of iron chlorosis has recently been proved for Strategy 1 species, at acidic pH. However in calcareous conditions, the Si effect on Fe acquisition and distribution is still unknown. In this work, the effect of Si on Fe, Mn, Cu and Zn distribution was studied in rice (Strategy 2 species) under Fe sufficiency and deficiency. Plants (+Si or-Si) were grown initially with Fe, and then Fe was removed from the nutrient solution. The plants were then analysed using a combined approach including LA-ICP-MS images for each element of interest, the analysis of the Fe and Si concentration at different cell layers of root and leaf cross sections by SEM-EDX, and determining the apoplastic Fe, total micronutrient concentration and oxidative stress indexes. A different Si effect was observed depending on plant Fe status. Under Fe sufficiency, Si supply increased Fe root plaque formation, decreasing Fe concentration inside the root and increasing the oxidative stress in the plants. Therefore, Fe acquisition strategies were activated, and Fe translocation rate to the aerial parts was increased, even under an optimal Fe supply. Under Fe deficiency, +Si plants absorbed Fe from the plaque more rapidly than -Si plants, due to the previous activation of Fe deficiency strategies during the growing period (+Fe + Si). Higher Fe plaque formation due to Si supply during the growing period reduced Fe uptake and could activate Fe deficiency strategies in rice, making it more efficient against Fe chlorosis alterations. Silicon influenced Mn and Cu distribution in root. PMID- 29453093 TI - Instruments for evaluation of safety culture in primary health care: integrative review of the literature. AB - OBJECTIVES: This research aimed to conduct an investigation of the tools used to assess safety culture in the primary health care. STUDY DESIGN: Integrative review of the literature. METHODS: We conducted a literature search using an instrument that included quantitative assessments of safety culture, using the following databases: CINAHL, ScienceDirect, PubMed, BIREME, and SciELO. Retrieved material comprised original articles published from 1998 to 2014, with titles and abstracts available in English, Portuguese, Spanish, and French. RESULTS: The search resulted in seven instruments; however, only three were primary healthcare focused. CONCLUSION: Most of the existing instruments for assessing safety culture have acceptable psychometric properties. The study serves as a source for students, workers, and researchers who want to know more about appropriate instruments for evaluating safety culture in primary care. PMID- 29453094 TI - A multidisciplinary study of 3-(beta-d-glucopyranosyl)-5-substituted-1,2,4 triazole derivatives as glycogen phosphorylase inhibitors: Computation, synthesis, crystallography and kinetics reveal new potent inhibitors. AB - 3-(beta-d-Glucopyranosyl)-5-substituted-1,2,4-triazoles have been revealed as an effective scaffold for the development of potent glycogen phosphorylase (GP) inhibitors but with the potency very sensitive to the nature of the alkyl/aryl 5 substituent (Kun et al., Eur. J. Med. Chem. 2014, 76, 567). For a training set of these ligands, quantum mechanics-polarized ligand docking (QM-PLD) demonstrated good potential to identify larger differences in potencies (predictive index PI = 0.82) and potent inhibitors with Ki's < 10 MUM (AU-ROC = 0.86). Accordingly, in silico screening of 2335 new analogues exploiting the ZINC docking database was performed and nine predicted candidates selected for synthesis. The compounds were prepared in O-perbenzoylated forms by either ring transformation of 5-beta-d glucopyranosyl tetrazole by N-benzyl-arenecarboximidoyl chlorides, ring closure of C-(beta-d-glucopyranosyl)formamidrazone with aroyl chlorides, or that of N (beta-d-glucopyranosylcarbonyl)arenethiocarboxamides by hydrazine, followed by deprotections. Kinetics experiments against rabbit muscle GPb (rmGPb) and human liver GPa (hlGPa) revealed five compounds as potent low MUM inhibitors with three of these on the submicromolar range for rmGPa. X-ray crystallographic analysis sourced the potency to a combination of favorable interactions from the 1,2,4 triazole and suitable aryl substituents in the GP catalytic site. The compounds also revealed promising calculated pharmacokinetic profiles. PMID- 29453095 TI - Simultaneous measurement of contents of liquirtin and glycyrrhizic acid in liquorice based on near infrared spectroscopy. AB - OBJECTIVE: To establish calibration models for simultaneous determination of contents of liquirtin and glycyrrhizic acid, and to investigate the variable selection methods. METHODS: The contents of liquirtin and glycyrrhizic acid determined by HPLC were as the reference values, which were associated with samples spectra by using near infrared spectrum (NIR) analysis technology. Calibration models were developed using partial least squares (PLS) regression algorithm, and evaluated by the independent dataset test with calculating the metrics of coefficients of determination of calibration and prediction (R2c, R2p), the root mean square errors of calibration and prediction (RMSEC, RMSEP), the mean absolute errors of calibration and prediction (MAEC, MAEP), and the residual prediction deviation (RPD). Five variable selection methods including variable importance in projection (VIP), competitive adaptive reweighted sampling (CARS), Monte Carlo uninformative variable elimination (MCUVE), particle swarm optimization (PSO) and genetic algorithm (GA), were investigated. RESULTS: Compared to the original full spectra, both quantification models for liquirtin and glycyrrhizic acid performed better with a clear ranking of GA>PSO>CARS>MCUVE?VIP>Full. Especially for GA-PLS models, RMSEC and RMSEP were <0.05%, R2c and R2p were >0.94, and RPD were both >4, indicating that both the models had good robustness and excellent prediction accuracy. CONCLUSION: The present calibration models can be utilized to simultaneously determine the contents of liquirtin and glycyrrhizic acid in liquorice samples, and thus are of great help for rapid quality evaluation and control of liquorice. PMID- 29453096 TI - Design of mitochondria-targeted colorimetric and ratiometric fluorescent probes for rapid detection of SO2 derivatives in living cells. AB - Two mitochondria-targeted colorimetric and ratiometric fluorescent probes for SO2 derivatives were constructed based on the SO2 derivatives-triggered Michael addition reaction. The probes exhibit high specificity toward HSO3-/SO32- by interrupting their conjugation system resulting in a large ratiometric blue shift of 46-121nm in their emission spectrum. The two well-resolved emission bands can ensure accurate detection of HSO3-. The detection limits were calculated to be 1.09 and 1.35MUM. Importantly, probe 1 and probe 2 were successfully used to fluorescence ratiometric imaging of endogenous HSO3- in BT-474 cells. PMID- 29453097 TI - Self-assembled vertically aligned Au nanorod arrays for surface-enhanced Raman scattering (SERS) detection of Cannabinol. AB - Self-assembled multi-layered vertically aligned gold nanorod (AuNR) arrays have been fabricated by a simple preparation process that requires a balance between the particle concentration and the ionic strength of the solvent. An experimentally determined critical AuNR concentration of 2.0nM and 50mM NaCl produces well-ordered vertically aligned hexagonally close-packed AuNR arrays. We demonstrate surface treatment via UV Ozone cleaning of such samples to allow introduction of analyte molecules (benzenethiol and cannabinol) for effective surface enhanced Raman scattering detection. This is the first demonstration of the SERS analysis of cannabinol. This approach demonstrates a cost-effective, high-yield and simple fabrication route to SERS sensors with application in the screening for the cannabinoids. PMID- 29453098 TI - Control of viral transcripts as a concept for future HBV therapies. AB - Chronic hepatitis B virus infections affect over 250 million people world-wide, and, at present, are not curable. Of those, over 800000 are expected to die yearly from complications including cirrhosis and primary hepatocellular carcinoma (HCC). A viral episomal DNA intermediate, covalently closed circular DNA (cccDNA) can persist in nuclei of infected hepatocytes and trigger production of infectious virus. Current standard of care treatments against chronic HBV infections primarily rely on nucleoside analogs (NA) that inhibit de novo virus production by inhibiting the viral reverse transcriptase and, as a consequence, reducing virus titers. However, they cannot cure infections, because they do not directly target cccDNA persistence. Nevertheless, NA therapies can halt progression of liver disease including cirrhosis and can reduce the development of hepatocellular carcinoma (HCC). A cure for chronic hepatitis B (CHB) must reduce the load of cccDNA or permanently silence transcription from cccDNA, and ensure sustained activation of an adaptive immune response that prohibits reactivation and spread of residual virus in the liver. As discussed in this review, novel technologies enabling genetic destruction of cccDNA and advances in our understanding of HBV transcriptional control provide exciting opportunities for the future development of curative therapies desperately needed to reduce the burden of chronic HBV infections. PMID- 29453099 TI - Impact of integrated viral DNA on the goal to clear hepatitis B surface antigen with different therapeutic strategies. AB - A hallmark of hepatitis B virus (HBV) infection is the presence of hepatitis B surface antigen (HBsAg) in the serum of patients. Sustained loss of HBV DNA and HBsAg from the blood are main goals for treatment, and considered as functional cure. It is rarely achieved with long-term nucleoside analogue treatment though, both because cccDNA, the template for viral replication, is not completely cleared, and probably also because hepatocytes with HBV DNA integrated into their chromosomes persist and continue to produce large amounts of HBsAg. Therefore, loss of HBsAg requires that both cccDNA and integrated DNA are cleared or their expression blocked. Recent data indicate that this may be achieved in some patients by stopping nucleoside analogue treatment, and that HBsAg-levels can be reduced by using specific interfering RNA. In the future, targeted degradation or disruption of HBV DNA might be possible using genome editing techniques such as CRISPR/Cas9. PMID- 29453100 TI - Nanoscale zero-valent iron assisted phytoremediation of Pb in sediment: Impacts on metal accumulation and antioxidative system of Lolium perenne. AB - Lead (Pb) is a highly toxic environmental pollutant, and could result in toxic effects on living organisms. The effects of 0, 100, 200, 500, 1000 and 2000 mg/kg of nZVI on plant growth, Pb accumulation and antioxidative responses of Lolium perenne were investigated. Results showed that the total Pb contents in L. perenne with the treatment of low concentrations of nZVI (100, 200 and 500 mg/kg) were higher than those in the non-nZVI treatments, and the highest Pb accumulation capacity of 1175.40 MUg per pot was observed in L. perenne with the treatment of 100 mg/kg nZVI. However, the total Pb contents in L. perenne decreased at high concentrations of nZVI (1000 and 2000 mg/kg). This might be resulted from the decrease of photosynthetic chlorophyll content and the aggravated oxidative stress induced by the high concentration of nZVI, which caused the decrease of plant biomass and metal accumulation capacity in plant. Moreover, the sequential extraction experiments results showed that the lowest acid soluble fraction of Pb in the sediments was found in the treatment with 100 mg/kg of nZVI, indicating that 100 mg/kg was the optimum concentration for nZVI to assist the phytoremediation of Pb-polluted sediment. To conclude, these findings provide a promising method to remediate Pb-polluted sediment by nZVI assisted phytoremediation. PMID- 29453101 TI - Can higher training practice dosage with treadmill slip-perturbation necessarily reduce risk of falls following overground slip? AB - BACKGROUND: Perturbation training is an emerging paradigm to reduce idiopathic falls (without clinical signs or symptoms) in older adults. While a higher threat dosage (intensity) in motor learning often directly relates to greater adaptation, retention, and generalization, little is known whether increasing the practice dosage (repetition) of slip-perturbation training would necessarily improve its outcomes. RESEARCH QUESTION: Can higher practice dosage of treadmill slip-perturbation training lead to greater generalization to an overground slip immediately after the training? METHODS: Forty-five community-dwelling older adults (73.5 +/- 5.6 years old) participated in the present study. They were conveniently assigned to three groups with equivalent treadmill walking duration: treadmill slip-perturbation training group with 40 practice dosage, 24 practice dosage, and zero practice dosage (without slip-perturbation). Later on during overground walking, all of them were exposed to the same generalization test (a novel slip on a walkway). Their recovery outcomes (fall, or no fall; balance loss, or no balance loss) and center of mass stability were compared. RESULTS: Higher practice dosage did not show significantly less incidence of fall, balance loss, or greater stability in comparison to lower practice dosage (p > .05). The present study showed that there was no evidence of dose-response relationship when the practice dosage was set above the 24 trials of practice dosage in treadmill slip-perturbation training. SIGNIFICANCE: Contrary to our hypothesis, increased practice dosage (40-slips) in treadmill slip-perturbation training from the commonly used threshold (24-slips) did not necessarily benefit immediate generalization from treadmill to overground walking among community-dwelling older adults. PMID- 29453102 TI - Preparation of PLGA/Rose Bengal colloidal particles by double emulsion and layer by-layer for breast cancer treatment. AB - The use of colloidal particles (CPs) in the transport of drugs is developing rapidly thanks to its effectiveness and biosafety, especially in the treatment of various types of cancer. In this study Rose Bengal/PLGA CPs synthesized by double emulsion (W/O/W) and by electrostatic adsorption (layer-by-layer), were characterized and evaluated as potential breast cancer treatment. CPs were evaluated in terms of size, zeta potential, drug release kinetics and cell viability inhibition efficacy with the triple negative breast cancer cell line HCC70. The results showed that both types of CPs can be an excellent alternative to conventional cancer treatment by taking advantage of the enhanced permeation and retention (EPR) effect, manifested by solid tumors; however, the double emulsion CPs showed more suitable delivery times of up to 60% within two days, while layer-by-layer showed fast release of 50% in 90 min. Both types of CPs were capable to decrease cell viability, which encourage us to further testing in in vivo models to prove their efficacy and feasible use in the treatment of triple negative breast cancer. PMID- 29453103 TI - Free-standing red phosphorous/silver sponge monolith as an efficient and easily recyclable macroscale photocatalyst for organic pollutant degradation under visible light irradiation. AB - Traditional nano-sized photocatalysts in powdery form suffer from difficulties in recyclability, and have to be immobilized before practical applications. In this study, red phosphorous/silver (red P/Ag) sponge monolith was discovered to be a new free-standing macroscale photocatalyst, which was fabricated by a one-pot hydrothermal method without using any organic surfactants or templates for the first time. The elemental red P not only functioned as a reducing agent in the formation of Ag sponge monolith during the synthesis processes, but also as the active photocatalyst in-situ immobilized onto the Ag sponge. The as-prepared red P/Ag sponge monolith showed enhanced photocatalytic activity than that of traditional pure powdery red P by a factor of 3.1 times for organic pollutants (i.e. Rhodamine 6G, phenol) degradation under visible light irradiation. The enhancement was mainly attributed to the function of Ag sponge served as good electron sink to trap photo-generated electrons. More importantly, such free standing macroscale photocatalyst can be easily recycled without activity deterioration. As a proof of concept, this work provides new insights into not only for the development of red P-based elemental photocatalysts, but also for the one-pot fabrication of novel free-standing macroscale materials with excellent photocatalytic activity for practical environmental applications. PMID- 29453104 TI - Controlling shape anisotropy of hexagonal CdS for highly stable and efficient photocatalytic H2 evolution and photoelectrochemical water splitting. AB - Photocorrosion and low solar conversion efficiency hindered widely applications of CdS in photocatalytic (PC) H2 evolution and photoelectrochemical (PEC) water splitting. Hence, this work reports the shape anisotropy of hexagonal CdS possesses highly stable and efficient PC H2 evolution and PEC water splitting by simply mixed diethylenetriamine (DETA) and deionized water (DIW) solvothermal. Here we demonstrate that the shape of hexagonal CdS plays an important role in their PC activity. The CdS-Nanorod yields optimal 5.4 mmol/g/h PC H2 production and photocurrent density 2.63 mA/cm2 at open circuit potential (OCP). The enhanced performance is attributed to the effective separation and transport of the photogenerated electron-hole pairs, which were verified by PL and transisent absorbance. Moreover, hexagonal CdS-Nanorod shows long-term PC H2 production and highly stable photocurrent density. As compared with CdS-Nanosphere, the hexagonal CdS-Nanorod exhibits 27 times and 19.2 times in H2 production and photocurrent density, respectively. What's more, STH efficiency of hexagonal CdS Nanorod is 3.23% and an impressive applied bias photon-to-current efficiency (ABPE) is 2.63% at 0.134 V (vs. RHE). Temperature is also explored and reported. The possible mechanism of PC H2 evolution and PEC water spiltting are proposed for CdS-Nanorod. This work may provide a promising strategy to fabricate efficient PC and PEC systems for solar-to-fuel energy conversion. PMID- 29453105 TI - Highly efficient and selective removal of N-heterocyclic aromatic contaminants from liquid fuels in a Ag(I) functionalized metal-organic framework: Contribution of multiple interaction sites. AB - An adsorbent with multiple interaction sites for the adsorption of nitrogen containing compounds (NCCs) has been realized in a silver ion functionalized Cr3+ based metal-organic framework (Cr)-MIL-101-SO3Ag. The adsorptive denitrogenation performance of (Cr)-MIL-101-SO3Ag was evaluated in a batch adsorption system in terms of both its adsorption capacity and selectivity, of which, quinoline and indole were selected as representative organonitrogen contaminants in liquid fuels. (Cr)-MIL-101-SO3Ag could interact with NCCs through multiple ways simultaneously, which exhibited about 50% higher adsorption capacity compared to (Cr)-MIL-101-SO3H, and a still high level of adsorption amount could be remained even in a model fuel where toluene (15% v) was added as a co-solvent and benzothiophene (BT) was added as a competitive adsorbate. The highly efficient and selective denitrogenation performance, we speculated was a combined results of these multiple interaction sites. The immobilized Ag(I) sites could strongly interact with NCCs through pi-complexation, which was thought to be responsible for its high adsorption capacity, meanwhile, the hard lewis acid site (Cr3+), which could preferentially interact with the hard nitrogen bases and the acid base interaction between nitrogen bases and remaining -SO3H groups endowed (Cr) MIL-101-SO3Ag with high selectivity over BT and other aromatic compounds. Futhermore, the enhanced interaction of (Cr)-MIL-101-SO3Ag with NCCs was also confirmed from the IR spectra with the significantly enhanced absorbance peak at 806 or 745 cm-1 observed for QUI and IND, respectively when compared to BT. After five successive adsorption-desorption cycles, the adsorption capacity of (Cr)-MIL 101-SO3Ag was almost unchanged, and the structural stability was well maintained, making it a potential adsorbent for deep denitrogenation of liquid fuels. PMID- 29453106 TI - Regionalized and vectorial charges transferring of Cd1-xZnxS twin nanocrystal homojunctions for visible-light driven photocatalytic applications. AB - In photocatalyst designing, quick recombination of photo-generated electron-hole pairs in the bulk or on the surface of semiconductors is a major limiting factor in achieving high photocatalytic efficiency, which is one of the most knotty scientific issues. For this purpose, a series of Cd1-xZnxS twin nanocrystal (NC) zinc blende/wurtzite (ZB/WZ) homojunctions photocatalysts were synthesized by a facile solvothermal route and innovatively employed in photocatalytic degradation. In sample Cd0.6Zn0.4S, ZB and WZ phases have the largest distribution and closest interconnection at atomic level. The type-II staggered band alignment formed between two phases made photo-generated electrons and holes spatially separated to ZB (away from twin plane) and WZ (to twin plane) regions, and the ordered arrangement of redox reaction's active sites was then realized inside a single semiconductor. Finally, photocatalytic activities of the samples were evaluated by degradation of methylene blue (MB) upon visible light irradiation. The optimal Cd0.6Zn0.4S NCs without any co-catalyst loading showed high photocatalytic activity with degradation efficiency of 95% in 80 min and performed excellent photostability. Furthermore, photocatalytic degradation and electron transfer mechanisms in Cd0.6Zn0.4S twin NCs are studied particularly. Inner twin structure homojunction has provided a new insight into the crystalline phase engineering. PMID- 29453108 TI - Telomeres and telomerase in heart regeneration. AB - Although recent advances have overturned the old view of the human heart as an inert postmitotic organ, it is clear that the adult heart's capacity to regenerate after an ischemic episode is very limited. Unlike humans, zebrafish and other lower vertebrates vigorously regenerate damaged myocardium after cardiac injury. Understanding how the zebrafish is able to conserve life-long cardiac regeneration capacity while mammals lose it soon after birth is crucial for the development of new treatments for myocardial infarction. Mammals and lower vertebrates differ markedly in their rates of cardiomyocyte proliferation and levels of telomerase activity. Here, we review recent discoveries identifying lack of telomerase activity and concomitant telomere dysfunction as natural barriers to cardiomyocyte proliferation and cardiac regeneration. PMID- 29453107 TI - Body fluid identification using a targeted mRNA massively parallel sequencing approach - results of a EUROFORGEN/EDNAP collaborative exercise. AB - In a previous study we presented an assay for targeted mRNA sequencing for the identification of human body fluids, optimised for the Illumina MiSeq/FGx MPS platform. This assay, together with an additional in-house designed assay for the Ion Torrent PGM/S5 platform, was the basis for a collaborative exercise within 17 EUROFORGEN and EDNAP laboratories, in order to test the efficacy of targeted mRNA sequencing to identify body fluids. The task was to analyse the supplied dried body fluid stains and, optionally, participants' own bona fide or mock casework samples of human origin, according to specified protocols. The provided primer pools for the Illumina MiSeq/FGx and the Ion Torrent PGM/S5 platforms included 33 and 29 body fluid specific targets, respectively, to identify blood, saliva, semen, vaginal secretion, menstrual blood and skin. The results demonstrated moderate to high count values in the body fluid or tissue of interest with little to no counts in non-target body fluids. There was some inter-laboratory variability in read counts, but overall the results of the laboratories were comparable in that highly expressed markers showed high read counts and less expressed markers showed lower counts. We performed a partial least squares (PLS) analysis on the data, where blood, menstrual blood, saliva and semen markers and samples clustered well. The results of this collaborative mRNA massively parallel sequencing (MPS) exercise support targeted mRNA sequencing as a reliable body fluid identification method that could be added to the repertoire of forensic MPS panels.

AB - Diabetic kidney disease and other long-term complications are common in diabetes, and comprise the main cause of co-morbidity and premature mortality in individuals with diabetes. While familial clustering and heritability have been reported for all diabetic complications, the genetic background and the molecular mechanisms remain poorly understood. In recent years, genome-wide association studies have identified a few susceptibility loci for the renal complications as well as for diabetic retinopathy, diabetic cardiovascular disease and mortality. As for many complex diseases, the genetic factors increase the risk of complications in concert with the environment, and certain associations seem specific for particular conditions, for example, SP3-CDCA7 associated with end stage renal disease only in women, or MGMT and variants on chromosome 5q13 associated with cardiovascular mortality only under tight glycaemic control. The characterization of the phenotypes is one of the main challenges for genetic research on diabetic complications, in addition to an urgent need to increase the number of individuals with diabetes with high quality phenotypic data to be included in future genetic studies. PMID- 29453110 TI - Genetics of type 1 diabetes. AB - Type 1 diabetes is the most common autoimmune disorder in childhood, characterized by the development of autoimmunity through unknown environmental insults in genetically susceptible individuals. There are now over 50 regions of the genome that harbor type 1 diabetes susceptibility genes, with much of the genetic risk now well-defined in youth of Northern European ancestry. The impact of these genetic variants on initiation and progression of the autoimmune process (islet autoimmunity) is now being understood; however, studies are only now being conducted to understand the function of the variants associated with type 1 diabetes risk. The characteristics of genetic risk of type 1 diabetes across the age spectrum suggests extensive complexity in biological and environmental mechanisms. We propose that both genetic and environmental factors attributed to type 1 and type 2 diabetes may contribute to beta-cell death through multiple mechanisms, leading to the clinical outcome of type 1 diabetes. PMID- 29453111 TI - Febrile infection-related epilepsy syndrome (FIRES): therapeutic complications, long-term neurological and neuroimaging follow-up. AB - PURPOSE: To understand the long-term neurological outcomes and chronological changes of brain MRIs in patients with febrile infection-related epilepsy syndrome (FIRES). METHODS: From December 2000 to May 2016, 29 patients diagnosed with FIRES were collected retrospectively. The demographic distribution, clinical manifestations, neuroimaging findings, and treatment methodology were described. Follow-up clinical outcomes and chronological evolution of neuroimaging findings were analyzed. RESULTS: The median age of disease onset was 8.9 years. The median duration of hospitalization was 87 days. During the period of hospitalization, more than 50% of patients exhibited complications such as skin rash, liver function impairment, and arrhythmia. Abnormal findings were found in 38% of neuroimaging studies in the initial study and in 87% of the follow-up brain MRI. Focal abnormal signal changes over the periventricular white matter suggested the more extensive lesions would be associated with a poorer clinical outcome. The median duration of follow-up was 5 years in 23 patients. In total, 87% of patients exhibited residual and/or refractory epilepsy. Regarding cognitive function, 26% of patients had normal intelligence quotient, 26% had learning disability and mild to moderate mental retardation, and 48% had severe mental retardation or vegetative status. The mortality rate at acute stage was 10%, and that at chronic stage was 13%. CONCLUSIONS: Liver function impairment, skin rash, and arrhythmia are frequently seen during hospitalization for FIRES at the acute stage of disease course. The higher grade of periventricular white matter lesions suggested poorer neurological outcomes. Studies on the pathomechanism of FIRES are crucially needed so that new treatment strategies for FIRES can be developed, which may improve long-term outcomes. PMID- 29453112 TI - Pattern and determinants of self-reported enacted stigma among rural dwellers living with epilepsy attending a tertiary health facility in Enugu State Nigeria. AB - PURPOSE: Epilepsy related stigma is a barrier to recovery and has been linked to a broad range of psychosocial consequences and has the potential to influence the provision of care to people with epilepsy. Understanding the determinants of enacted stigma in epilepsy is relevant in the understanding of the burden of epilepsy in Nigeria. METHOD: Using a semi-structured questionnaire, a cross sectional descriptive study was conducted among rural dwellers receiving treatment for epilepsy in a tertiary referral specialist hospital in Enugu, south east Nigeria. RESULTS: The participants consisted of 108 patients, 63% of whom were males. Most patients 99(91.7%) reported experiencing stigma in the past. The commonest forms of enacted stigma were being regarded as having 'spiritual attack' 88(81.5%) and restraining from interacting with others 49(45.4%). Most individuals who received nonorthodox treatment 55(55.6%) experienced stigma. Severely stigmatized individuals were more likely to be females. Age of onset of epilepsy, use of non-orthodox treatment, seizures occurrence in public places and the presence of physical injuries positively correlated with enacted stigma. CONCLUSIONS: The burden of epilepsy related enacted stigma is high among rural dwellers attending a tertiary medical outpatient clinic in Enugu, southeast Nigeria. PMID- 29453113 TI - Epidemiological profile of epilepsy in low income populations. AB - Epilepsy is a global disease with an unequal distribution. About 80% of the affected individuals reside in low and middle income countries. The incidence and prevalence of epilepsy in low income populations is higher than in the rest of the world, this is partly explained by some risk factors such as head trauma, perinatal injury and CNS infections, which are more common in poor regions, especially in rural areas. Epilepsy is considered a treatable condition with high rates of therapeutic response. About three fourths of patients achieve control of the disease with the use of antiepileptic drugs, however, despite this benign prognosis, over 75% of patients from low income populations do not receive treatment at all. The cultural beliefs, the inequity in the distribution of public health services, the inadequate supply of antiepileptic drugs, the low number of neurologists involved in the attention of epilepsy, and the social stigma, are the main reasons that increase the treatment gap and the burden of disease in low income populations with epilepsy. We conducted a narrative review regarding the epidemiology of epilepsy in low income populations by searching PubMed, EMBASE, Google Scholar and thoroughly examining relevant bibliographies. This review aims to summarize the main epidemiological aspects of epilepsy in LMIC, emphasizing on incidence, prevalence, socio-demographic profile, TG, social stigma and QoL. PMID- 29453114 TI - Levetiracetam monotherapy for the treatment of infants with epilepsy. AB - PURPOSE: Levetiracetam is a broad-spectrum anti-epileptic drug that is effective against both focal and generalized epilepsies. In this study, we aimed to evaluate the efficacy, tolerability and safety of levetiracetam monotherapy in the management of different seizure types in children with epilepsy under the age of two. METHOD: This retrospective study was conducted on children with a diagnosis of epilepsy from January 2014 to January 2017. To be included in the study, patients were required to be less than two years of age at the time levetiracetam was initiated as initial monotherapy and to be followed clinically for at least 6 months. RESULTS: Of the 92 patients, 61 (66%) patients were seizure free. Fifty-eight percent of the patients (31 of 53) with focal epilepsy were seizure free and 77% (30 of 39) generalized epilepsy were seizure free. We found that levetiracetam monotherapy was effective in both focal and generalized epilepsy. Levetiracetam monotherapy was significantly more effective in patients with unknown etiologies (p = 0.004). Seizure freedom rate under levetiracetam monotherapy was significantly higher in patients with normal psychomotor development (p = 0.000). Seizure freedom rate under levetiracetam monotherapy was significantly higher in patients with unknown etiologies and normal psychomotor development. Normal psychomotor development was the strongest predictor of seizure control under levetiracetam monotherapy (OR = 6; 95% CI = 2.3-16.0; p < 0.001). Five children (1%) reported irritability. No hematological or biochemical, or behavioral adverse side effects except irritability were reported in any children. No patient discontinued levetiracetam therapy because of treatment-related side effects. CONCLUSION: Our study showed levetiracetam to be an effective, well tolerated and safe agent for the treatment of a variety of seizure types and etiologies seen in infants.

AB - Building-integrated solar thermal (BIST) systems are a specific type of solar thermal systems which are integrated into the building and they participate in building functionality. The present article is about the life-cycle assessment of different options of a BIST system (Mediterranean climatic conditions: Ajaccio, France). The environmental profile of the studied configurations is assessed by means of CED (cumulative energy demand), GWP (global warming potential) and EPBT (energy payback time). The proposed configurations (for the collector) include: i) a system without PCM (phase change material) using only rock wool as insulation and ii) a system with PCM (myristic acid) and rock wool. Concerning life-cycle results based on CED and GWP 100a (scenario without recycling), the configuration without PCM shows 0.67 MJprim/kWh and 0.06 kg CO2.eq/kWh while the configuration with PCM presents 0.74 MJprim/kWh and 0.08 kg CO2.eq/kWh. Regarding EPBT, if the inputs for pumping/auxiliary heating are not taken into account, both configurations (with/without PCM) have almost the same EPBT (about 1.3 years). On the other hand, if the inputs for pumping/auxiliary heating are considered, EPBT is lower for the system with PCM. In addition, scenarios with recycling have been examined and the results demonstrate that recycling considerably improves the environmental profile of the studied configurations. PMID- 29453116 TI - Developing a methodology for real-time trading of water withdrawal and waste load discharge permits in rivers. AB - In this paper, a new methodology is proposed for the real-time trading of water withdrawal and waste load discharge permits in agricultural areas along the rivers. Total Dissolved Solids (TDS) is chosen as an indicator of river water quality and the TDS load that agricultural water users discharge to the river are controlled by storing a part of return flows in some evaporation ponds. Available surface water withdrawal and waste load discharge permits are determined using a non-linear multi-objective optimization model. Total available permits are then fairly reallocated among agricultural water users, proportional to their arable lands. Water users can trade their water withdrawal and waste load discharge permits simultaneously, in a bilateral, step by step framework, which takes advantage of differences in their water use efficiencies and agricultural return flow rates. A trade that would take place at each time step results in either more benefit or less diverted return flow. The Nucleolus cooperative game is used to redistribute the benefits generated through trades in different time steps. The proposed methodology is applied to PayePol region in the Karkheh River catchment, southwest Iran. Predicting that 1922.7 Million Cubic Meters (MCM) of annual flow is available to agricultural lands at the beginning of the cultivation year, the real-time optimization model estimates the total annual benefit to reach 46.07 million US Dollars (USD), which requires 6.31 MCM of return flow to be diverted to the evaporation ponds. Fair reallocation of the permits, changes these values to 35.38 million USD and 13.69 MCM, respectively. Results illustrate the effectiveness of the proposed methodology in the real-time water and waste load allocation and simultaneous trading of permits. PMID- 29453117 TI - Performance of integrated ferrate-polyaluminum chloride coagulation as a treatment technology for removing freshwater humic substances. AB - Ferrate-based technologies can play versatile roles in water treatment because of their potential for in situ production and because they do not form any harmful by-products. We compared the oxidative performance of Fe(VI) generated by an electrochemical process, with H2O2-UV irradiation (a standard oxidation process) for removing Suwannee River natural organic matter. It took only 5 min for Fe(VI) (Fe: 1.67 * 10-4 M) to reduce the fluorescence intensity of a humic-like fluorophore by 36% of the original value; in contrast, it took 120 min of irradiation using H2O2-UV ([OH] ~ 1.8 * 10-13 M) to remove 68% of the original value. In addition to the short reaction time, ferrate can also form aggregates that can remove turbidity and adsorb organics and other contaminants present in water. Simultaneous addition of ferrate and polyaluminum chloride (PACl) to unfiltered natural water displayed the most efficient reduction of UVA254, primarily under acidic conditions. Ferrate pre-oxidation followed by PACl coagulation was the most effective process for reducing turbidity and chromaticity, because of the effects arising from the coagulation of ferrate that resulted in Fe(III)(s) species. Ferrate pre-oxidation generated low-molecular weight UVA254-absorbing organics, whose dissolved organic matter (DOM) peak at 1250 Da was removed by PACl coagulation. Neither the initial pH nor the process order significantly affected the removal of organic carbon by the integrated ferrate-PACl process. PMID- 29453118 TI - Effects of forest regeneration practices on the flux of soil CO2 after clear cutting in subtropical China. AB - Reforestation after clear-cutting is used to facilitate rapid establishment of new stands. However, reforestation may cause additional soil disturbance by affecting soil temperature and moisture, thus potentially influencing soil respiration. Our aim was to compare the effects of different reforestation methods on soil CO2 flux after clear-cutting in a Chinese fir plantation in subtropical China: uncut (UC), clear-cut followed by coppicing regeneration without soil preparation (CC), clear-cut followed by coppicing regeneration and reforestation with soil preparation, tending in pits and replanting (CCRP), and clear-cut followed by coppicing regeneration and reforestation with overall soil preparation, tending and replanting (CCRO). Clear-cutting significantly increased the mean soil temperature and decreased the mean soil moisture. Compared to UC, CO2 fluxes were 19.19, 37.49 and 55.93 mg m-2 h-1 higher in CC, CCRP and CCRO, respectively (P < 0.05). Differences in CO2 fluxes were mainly attributed to changes in soil temperature, litter mass and the mixing of organic matter with mineral soil. The results suggest that, when compared to coppicing regeneration, reforestation practices result in additional CO2 released, and that regarding the CO2 emissions, soil preparation and tending in pits is a better choice than overall soil preparation and tending. PMID- 29453119 TI - An analysis of environmental incidents for a national Antarctic program. AB - Research stations in Antarctica are concentrated on scarce ice-free habitats. Operating these stations in the harsh Antarctic climate provides many challenges, including the need to handle bulk fuel and cargo increasing the risk of environmental incidents. We examined 195 reports of environmental incidents from the Australian Antarctic Program, spanning six years, to investigate the impacts and pathways of contemporary environmental incidents. Fuel and chemical spills were most common, followed by biosecurity incursions. The majority of reports were assessed as having insignificant actual impacts. Either the incidents were small, or active, rapid response and mitigation procedures minimised impact. During the period only one spill report (4000 l) was assessed as a 'high' impact. This is despite over 13 million litres of diesel utilised. The majority of incidents occurred within the existing station footprints. The pathways leading to the incidents varied, with technical causes predominately leading to spills, and procedural failures leading to biosecurity incursions. The large number of reports with inconsequential impacts suggest an effective environmental management system with a good culture of reporting environmental incidents. Our findings suggest that the key to continual improvement in an ongoing environmental management system is to learn from incidences and take action to prevent them occurring again, with an end-goal of minimising the residual risk as much as possible. PMID- 29453120 TI - Mycobiota and co-occurrence of mycotoxins in South African maize-based opaque beer. AB - Beer, a beverage consumed throughout the world, is mainly derived from cereals. In this study, fungal and mycotoxin contamination, as well as the physicochemical properties of maize-based opaque beer (umqombothi) obtained from the Gauteng province of South Africa, was investigated. The mean water activity, pH and total titratable acidity of the analysed beer samples were 0.91, 3.76 and 1.20% lactic acid, respectively. The investigation revealed Aspergillus, Penicillium, Phoma and Saccharomyces as the predominant fungal genera with a mean fungal load of 3.66 * 105 CFU/mL. Among the mycotoxigenic fungal species recovered, Aspergillus flavus had the highest incidence of 26%. Previously unreported strains such as P. chrysogenum strain AD25, A. sydowii strain AD 22 and A. tritici strain AD 11 were found. Furthermore, mycotoxin quantitative analysis via liquid chromatography tandem mass spectrophotometry showed that deoxynivalenol was the dominant mycotoxin occurring in 84% of the samples. This was followed by enniatin B that occurred in 75% of samples ranging from 12 to 44 MUg/L and fumonisin B1 (FB1) (incidence of 53% at a maximum level of 182 MUg/L). Generally, there was low occurrence aflatoxins, whereas T-2, HT-2, nivalenol, zearalenone, 3- and 15 acetyl-deoxynivalenol were not detected. All the samples analysed had safe levels of mycotoxins tested but were contaminated by at least two mycotoxins that could pose some additive or synergistic health effects among consumers. On average: a 60 kg adult consuming 1-6 L/day of the beer was exposed to FB1 + FB2 at an estimated 2.20-13.20 MUg/kg body weight/day. These values were far above the maximum tolerable daily intake of 2 MUg/kg bw/day established by the Joint FAO/WHO Expert Committee on Food Additives (JECFA). The study demonstrates that consumption of umqombothi can significantly enhance dietary exposure to multiple mycotoxins among consumers, and therefore accentuates the need for strategies aimed at reducing toxigenic fungal colonization and mycotoxin contamination in the beer processing chain. PMID- 29453121 TI - Regenerable urchin-like Fe3O4@PDA-Ag hollow microspheres as catalyst and adsorbent for enhanced removal of organic dyes. AB - In this work, novel urchin-like Fe3O4@polydopamine (PDA)-Ag hollow microspheres have been prepared via a facile synthesis method by in situ reduction and growth of Ag nanoparticles on mussel-inspired PDA layers coated on Fe3O4 hollow cores. The catalytic reduction efficiency and adsorption performance of the as-prepared urchin-like Fe3O4@polydopamine (PDA)-Ag hollow microspheres for model organic dyes (i.e., methylene blue and rhodamine B) under varying pH condition have been systematically investigated, which are demonstrated to be significantly enhanced as compared to that of spherical (relatively smooth) solid Fe3O4@PDA-Ag microspheres. The as-prepared urchin-like Fe3O4@PDA-Ag hollow microspheres show high reusability, easy separability, and fast regeneration ability, with no obvious drop in the catalytic and adsorption efficiency after cyclic reuse. The versatile PDA coatings on the urchin-like microspheres allow further surface functionalization for development of multifunctional catalyst and adsorbent materials. This work provides a very useful and facile methodology for synthesizing and tuning the urchin-like morphology of Fe3O4@PDA-Ag microspheres, with great potential applications in catalysis and wastewater treatment. PMID- 29453122 TI - Assessment of the potential hazard represented by natural raw materials containing mineral fibres-The case of the feldspar from Orani, Sardinia (Italy). AB - This work describes the nature of the potentially hazardous fibrous amphibole found in the Orani's feldspar mine (Sardinia, Italy). To identify its nature, a protocol of analysis including morphometric, chemical and crystallographic characterizations was applied. Thanks to this approach, it was possible to classify the observed fibres as tremolite after comparing chemical data, SEM/TEM observations, FTIR/ Raman spectra and X-ray diffraction data with those reported for a standard sample. The unit cell parameters of the investigated tremolite phase are a = 9.82(1) A, b = 18.08(3) A, c = 5.27(1) A, and the angle beta corresponds to 104.4(1) degrees . The mean concentration of asbestos tremolite in the Orani's feldspar is 0.28 wt%. Most of the fibres (0.26 wt%) are respirable 'regulated' fibres, representing a potential hazard. Because the total amount of tremolite in the sample is 0.6 wt%, a large fraction of it has a crystal habit other than fibrous-asbestiform or acicular. The obtained results allowed us to suggest possible solutions for a safe exploitation and mineral processing of the Orani's mine. The procedure proposed herein may be a general tool suitable to identify the mineralogical nature of fibrous minerals in raw materials and assess if they may represent a potential health/environmental hazard. PMID- 29453124 TI - Exploring the function of bacterial chemotaxis. AB - Bacterial chemotaxis is a classical subject: our knowledge of its molecular pathway has grown very detailed, and experimental observations, as well as mathematical models of the dynamics of chemotactic populations, have a history of several decades. This should not lead to the conclusion that only minor details are left to be understood. Indeed, it is believed that bacterial chemotaxis is under selection for efficiency, yet the underlying functional forces remain largely unknown. These aspects are discussed here by the presentation of illustrative examples related to the role of adaptation and signal integration. Both are expected to be important in ecologically relevant conditions, where chemotaxis should be strongly coupled with metabolism and growth, due to the presence of diverse chemoattractant cues and their active consumption by multiple types of bacteria competing for growth. PMID- 29453123 TI - An experiential model of education introduced to improve the confidence of student midwives in undertaking second stage management of the perineum (SSMP). AB - BACKGROUND AND OBJECTIVE: the limited availability of high quality evidence related to second stage management of the perineum (SSMP) combined with a perceived shift in UK practice towards a 'hands off' the perineum/fetal head approach are likely to have impacted significantly on student midwives' understanding of SSMP. This paper presents a classroom based educational session using low fidelity simulation, which was designed in response to student feedback and aimed to improve confidence in this skill. DESIGN: reflective teaching practice, based on evaluation of SSMP teaching. SETTING: an undergraduate midwifery programme based at an inner city university in London UK. PARTICIPANTS: student midwives. FINDINGS: the education session based on Kolb's experiential approach to learning appeared to address gaps in the previous teaching which was identified by students. The Classroom setting offered students a supportive setting in which to experiment with different SSMP approaches with a view to personalising care and without compromising safety. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: although further longitudnal research is needed, the experiential model appears to offer a low resource approach to teaching SSMP and has potential application in other countries.

PMID- 29453126 TI - PGY-specific benchmarks improve resident performance on Fundamentals of Laparoscopic Surgery tasks. AB - BACKGROUND: Although expert proficiency times for Fundamentals of Laparoscopic Surgery (FLS) tasks exist, these times are not always attainable for junior residents. We hypothesize that post-graduate year (PGY)-specific benchmarks will improve resident performance of FLS tasks. METHODS: In 2014, PGY-specific benchmarks were developed for FLS tasks for PGY1-PGY4 general surgery residents by averaging completion times for each task from 2007 to 2013. Resident performance on each FLS task and overall performance was compared for PGY1-PGY4 residents in the 2007-2013 group and the 2014-2016 group, before and after implementation of PGY-specific benchmarks. RESULTS: There was a significant improvement in FLS performance in the 2014-2016 group at the PGY1 (p = 0.01), PGY2 (p < 0.01), and PGY3 (p = 0.01) levels, but no difference at the PGY4 level (p = 0.71). CONCLUSIONS: PGY-specific benchmarks may improve efficacy of laparoscopic skills training for junior residents, increasing the efficiency of skill development. PMID- 29453127 TI - Generation of D1-1 TALEN isogenic control cell line from Dravet syndrome patient iPSCs using TALEN-mediated editing of the SCN1A gene. AB - Dravet syndrome (DS) is an infantile epileptic encephalopathy mainly caused by de novo mutations in the SCN1A gene encoding the alpha1 subunit of the voltage-gated sodium channel Nav1.1. As an in vitro model of this disease, we previously generated an induced pluripotent stem cell (iPSC) line from a patient with DS carrying a c.4933C>T (p.R1645*) substitution in SCN1A. Here, we describe developing a genome-edited control cell line from this DS iPSC line by substituting the point mutation with the wild-type residue. This artificial control iPSC line will be a powerful tool for research into the pathology of DS.

PMID- 29453129 TI - Efficient visible light induced synthesis of silver nanoparticles by Penicillium polonicum ARA 10 isolated from Chetomorpha antennina and its antibacterial efficacy against Salmonella enterica serovar Typhimurium. AB - The green synthesis of silver nanoparticles (AgNPs) using biological systems such as fungi has evolved to become an important area of nanobiotechnology. Herein, we report for the first time the light-induced extracellular synthesis of silver nanoparticles using algicolous endophytic fungus Penicillium polonicum ARA 10, isolated from the marine green alga Chetomorpha antennina. Parametric optimization, including the concentration of AgNO3, fungal biomass, ratio of cell filtrate and AgNO3, pH, reaction time and presence of light, was done for rapid AgNPs production. The obtained silver nanoparticles (AgNPs) were characterized by UV-Visible spectroscopy, Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy and Transmission electron microscopy (HRTEM-EDAX). The AgNPs showed a characteristic UV-visible peak at 430 nm with an average size of 10-15 nm. The NH stretches in FTIR indicate the presence of protein molecules. The Raman vibrational bands suggest that the molecules responsible for the reduction and stability of AgNPs were extracellular proteins produced by P.polonicum. Antibacterial evaluation of AgNPs against the major foodborne bacterial pathogen Salmonella enterica serovar Typhimurium MTCC 1251, was assessed by well diffusion, Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) assay. Killing kinetic studies revealed complete killing of the bacterial cells within 4 h and the bactericidal nature of synthesized nanoparticles was confirmed by fluorescent microscopy and scanning electron microscopy. Furthermore, the bactericidal studies with Transmission electron microscopy (TEM) at different time intervals explored the presence of AgNPs in the cell wall of S.Typhimurium at about 30 min and the complete bacterial lysis was found at 24 h. The current research opens an insight into the green synthesis of AgNPs and the mechanism of bacterial lysis by direct damage to the cell wall. PMID- 29453130 TI - Charting the development of cognitive mapping. AB - Developmental research beginning in the 1970s has suggested that children's ability to form cognitive maps reaches adult levels during early adolescence. However, this research has used a variety of testing procedures, often in real world environments, which have been difficult to share widely across labs and to use to probe components of mapping, individual differences in success, and possible mechanisms of development and reasons for individual variation. In this study, we charted the development of cognitive mapping using a virtual navigation paradigm, Silcton, that allows for testing samples of substantial size in a uniform way and in which adults show marked individual differences in the formation of accurate route representations and/or in route integration. The current study tested children aged between 8 and 16 years. In terms of components of normative development, children's performance reached adult levels of proficiency at around age 12, but route representation progressed significantly more quickly than route integration. In terms of individual differences, by age 12 children could be grouped into the same three categories evident in adults: imprecise navigators (who form only imprecise ideas of routes), non-integrators (who represent routes more accurately but are imprecise in relating two routes), and integrators (who relate the two routes and, thus, form cognitive maps). Thus, individual differences likely originate during childhood. In terms of correlates, perspective-taking skills predicted navigation performance better than mental rotation skills, in accord with the view that perspective taking operates on extrinsic spatial representations, whereas mental rotation taps intrinsic spatial representations. PMID- 29453131 TI - The incidence of associated abnormalities in patients with sacrococcygeal teratoma. AB - BACKGROUND: Gross genetic causes for SCT are unknown; however, it might be associated with other abnormalities. We assessed the incidence of associated abnormalities in a large national cohort of neonates with SCT and aimed to identify predictive risk factors. PROCEDURE: The medical records were reviewed of 235 consecutive neonates with SCT treated at the six pediatric surgical centers in the Netherlands from 1970 to 2010. Potential risk factors for associated abnormalities analyzed included sex, gestational age, tumor-volume/histology and Altman-classification. RESULTS: In 76 patients (32.3%) at least one associated abnormality was diagnosed, with hydronephrosis as the most common (16.2%) and hip dysplasia in 4.3%. Multiple abnormalities were documented for 21 (9.0%). Prematurity and Altman type IV SCT were associated with an increased risk of any associated abnormality. No association between increased tumor-volume and hydronephrosis or hip dysplasia was found. Patients with type IV Altman SCT had a fourfold risk of suffering from hydronephrosis compared to Altman type I SCT. CONCLUSIONS: SCT was associated with other abnormalities in one-third of children. Some were tumor-related while others were related to prematurity or occurred sporadically. In contrast to clinically obvious anomalies, hip dysplasia or hydronephrosis might be latently present with more subtle clinical presentation. We therefore suggest renal- and hip-ultrasound in all patients, certainly those with Altman type IV SCT. LEVEL OF EVIDENCE RATING: Level II (retrospective study). PMID- 29453132 TI - Malrotation is not associated with adverse outcomes after cardiac surgery in patients with heterotaxy syndrome. AB - BACKGROUND: Patients with heterotaxy syndrome (HS) often have asymptomatic malrotation. There is a lack of consensus regarding the management of these patients, particularly in patients with complex congenital heart disease (CHD). We sought to describe the prevalence of malrotation and incidence of volvulus in a population of patients with complex CHD and to identify the impact of malrotation on morbidity and mortality following cardiac surgery. METHODS: We performed a retrospective review of all patients with HS and complex CHD who required cardiac surgery in the first year of life at a single center between October 1995 and September 2015. Malrotation was diagnosed by abdominal imaging or by direct inspection during abdominal surgery. Demographic data was collected along with details of hospitalization following cardiac and GI surgeries. Descriptive analysis along with appropriate hypothesis testing was conducted to evaluate the results. RESULTS: We identified 49 patients with HS, 42 with single ventricle anatomy and 7 with biventricular anatomy. Of the 49 patients, 29 (59%) were diagnosed with malrotation, 6 (12%) had normal intestinal rotation, and 14 (29%) had no evaluation of intestinal rotation. The prevalence of malrotation in the population who underwent abdominal imaging was 29 out of 35 (83%). There was no difference in survival following cardiac surgery between patients with malrotation and those with unknown or normal intestinal anatomy. Comparing patients with malrotation and patients with normal or unknown intestinal rotation, there was also no difference in surrogate markers of morbidity. Of the 29 patients with known malrotation, only 2 patients (7%) underwent therapeutic Ladd procedures and 19 (65%) underwent prophylactic Ladd procedures. CONCLUSIONS: We conclude that the outcomes following cardiac surgery for patients with HS are not impacted by the presence of malrotation. Furthermore, we also found that the incidence of volvulus in the studied group is low. Given these findings, and the understanding that patients with HS and significant CHD are frequently tenuous and high risk surgical candidates, we do not believe performing prophylactic Ladd procedures is warranted.

AB - CONTEXT/BACKGROUND: To determine risk of 30-day mortality for premature infants undergoing abdominal operations during the first 2 months of life and to identify risk factors for perioperative mortality using available demographic and clinical variables of interest. BASIC PROCEDURES: Retrospective descriptive analysis of premature infants (gestational age less than or equal to 36weeks) undergoing abdominal operations during the first 2 months of life using the American College of Surgeon's National Surgical Quality Improvement Project Pediatric (NSQIP-P, 2012-2015) database. A stepwise logistic regression model incorporating multiple demographic and clinical factors was constructed to identify independent predictors of 30-day mortality. FINDINGS: A total of 1554 premature infants were identified who underwent abdominal operations during the first 2 months of life. Unadjusted 30-day mortality ranged from 31% for infants born <24weeks gestational age to 4.9% for those born at 35-36weeks. Increased gestational age corresponded to decreased risk of mortality but week-by-week was not independently predictive of mortality in multivariate modeling. Female sex (aOR 1.51, 95% C.I. 1.08-2.10, p=0.014), inotrope support (aOR 3.46, 95% C.I. 2.43-4.92, p<0.001), ventilator use (aOR 2.86, 95% C.I. 1.56-5.25, p<0.001) and American Society of Anesthesiologists (ASA) class 3 (aOR 4.14, 95% C.I. 1.58-10.81, p=0.004) at time of operation were all associated with significantly increased risk of 30-day mortality. On stepwise logistic regression incorporating only those variables with statistical significance, female sex, inotrope, and ventilator support retained statistical significance. CONCLUSIONS: Premature infants undergoing abdominal operations during the first 2 months of life have expectedly high risk of 30-day mortality. Female sex, inotrope, and ventilator support are independently associated with increased risk of mortality and can be incorporated into a model where, if present, risk of mortality is greater than 14.2%.

AB - We examined transgenerational effects of exposure to copper on early development of offspring in the urchin Evechinus chloroticus, and whether parental exposure mediated offspring response to a further low level exposure to copper during early development. Month-long exposure to elevated copper (25 MUgL-1) in the laboratory increased copper in gonads of both males and females and reduced gonad size by almost half. There was a negative relationship between adult size and copper burden. Normal larval development and larval size four days after fertilization were both strongly, negatively related to the amount of copper in female gonads in a dose-dependent manner, but fertilization success was unaffected. This demonstrates a transgenerational effect of maternal exposure to copper pollution on offspring performance that is mediated by individual traits of females, but no evidence of strong paternal effects, nor of a low level of copper in the water in which early development occurs. PMID- 29453135 TI - Dual inhibitors of the pro-survival proteins Bcl-2 and Mcl-1 derived from natural compound meiogynin A. AB - Thirty analogues of natural meiogynin A, a pan-Bcl-2 inhibitor, were prepared in order to elaborate cytotoxic compounds on specific cancer cells overexpressing one or more proteins of the Bcl-2 family. The interaction of all the new analogues with Bcl-xL, Mcl-1 and Bcl-2 proteins was first evaluated by fluorescence polarization assay (FPA) and showed that modulation of the lateral chain has a dramatic impact as subtle changes significantly modify the activity on the target proteins. The acetoxymethyl prodrugs of the two most active compounds were then elaborated to determine their cytotoxicity on B cell lines. A strong cytotoxic effect on BL2, RS4;11 and H929 cells was observed with a triazole prodrug that induces apoptosis.

PMID- 29453137 TI - Scientific evidence on perineal trauma during labor: Integrative review. AB - OBJECTIVE: To assess the scientific evidence for management and preservation of perineal integrity during the expulsive stage of labor. STUDY DESIGN: Integrative review that employed the Population, Intervention, Comparison, Outcome strategy to formulate the research question: Which perineal measure(s) is(are) effective in maintaining perineal integrity during labor? The search was performed in the databases MEDLINE, LILACS, BDENF and SciELO. The ten selected studies were analyzed based on their level of evidence and grade of recommendation. RESULTS: Four categories of measures were located: antenatal perineal care, perineal massage during the expulsive phase of labor, manual perineal support during the expulsive phase of labor and perineal hyaluronidase injection. CONCLUSION: Based on its level of evidence, perineal massage with lubricants performed by the women or their partners at the end of pregnancy may be recommended as a measure favorable for perineal protection. PMID- 29453138 TI - Increased coagulation index as measured by Thromboelastography during ovarian stimulation for in vitro fertilization: Influence of the final oocyte maturation triggering agent. AB - OBJECTIVE: Thromboelastography (TEG) is a viscoelastic test of hemostasis which allows measurement of the processes of clot initiation, propagation, stabilization, and dissolution in real time. In this study we aimed to evaluate the alterations in coagulation as measured by TEG during In Vitro Fertilization (IVF) stimulation cycles and to investigate whether final oocyte maturation with recombinant hCG (rhCG) versus GnRH agonist results in a different coagulation state. STUDY DESIGN: This is a prospective observational study which included fifty-three normogonadotrophic women. All the patients received an antagonist IVF treatment protocol. Final oocyte maturation was triggered with either rhCG (n = 25) or GnRH agonist (n = 26). Two patients did not complete the study due to poor response. Venous blood was drawn in the early and late follicular phase and on the day of ovum pickup. The TEG parameters assessed were R (time to first clot formation), K (time until the clot reaches a fixed strength), alpha angle (the rate of clot formation), MA (reflects maximum strength of the platelet-fibrin clot), LY30 (percent of clot lysis at 30 min after MA is reached) and the CI (the overall coagulability). RESULTS: The overall coagulation index of the entire study population was significantly increased on the day of ovum pickup as compared to the early follicular phase. This increase in the coagulation index was also significant in a subanalysis of patients triggered with rhCG. Contrarily, there was no significant increase in the coagulation index in the subgroup of patients triggered with GnRH agonist. CONCLUSION: Our results demonstrate a procoagulable state in patients after ovulation induction. Final triggering with GnRH agonist rather than rhCG, might lower this hypercoagulability pattern. PMID- 29453140 TI - Serum apolipoprotein A-1 concentrations and the prevalence of cardiovascular autonomic neuropathy in individuals with type 2 diabetes. AB - OBJECTIVE: To evaluate the relationship between levels of serum apolipoproteins and the prevalence of cardiovascular autonomic neuropathy (CAN) in type 2 diabetes. METHODS: In total, 3199 individuals with type 2 diabetes were investigated in a cross-sectional study. The diagnosis of CAN was made based on the results of a cardiovascular reflex test. Serum apolipoprotein A-I (apoA-I) and apolipoprotein B (apoB) levels were measured. RESULTS: Serum apoA-1 levels were significantly low in individuals with CAN, but there was no significant association between serum apoB levels and CAN. According to the degree of cardiovascular autonomic dysfunction, the average apoA-I levels were significantly different after adjusting for other covariates (normal, 1.32 g/l, 95% confidence interval [CI] 1.30-1.35; early, 1.29 g/l, 95% CI 1.27-1.31; definite, 1.27 g/l, 95% CI 1.25-1.30; P for trend = 0.010). In the multivariable analysis, the statistically significant association between apoA-I and CAN remained after adjusting for the risk factors (odds ratio per standard deviation increase in the log-transformed value, 0.65; 95% CI, 0.43-0.97, P = 0.036). Additional adjustments for serum high-sensitivity C-reactive protein (or fibrinogen) concentrations eliminated this relationship. CONCLUSIONS: Serum apoA I levels are inversely associated with the prevalence of CAN in individuals with type 2 diabetes. Our data also suggest that a putatively increased risk of CAN associated with decreased apoA-I levels might be mediated by correlated increases in the levels of inflammatory markers. PMID- 29453139 TI - Effect of inhaled corticosteroids on lung function in chronic beryllium disease. AB - BACKGROUND: The clinical effects of inhaled corticosteroids (ICS) on chronic beryllium disease (CBD) are unknown. Although frequently used for symptoms or disease not requiring systemic therapy, the clinical course of patients on ICS has not been evaluated. METHODS: In a retrospective cohort study, forty-eight subjects with CBD, diagnosed by granulomas on lung biopsy and treated with inhaled corticosteroids, were matched to sixty-eight subjects with CBD who were not treated. Pulmonary function testing, exercise tolerance, blood BeLPT, BAL cell count, and symptoms were evaluated. RESULTS: Treated patients showed no significant change over time in pulmonary function, when compared to controls, by forced vital capacity (FVC, p = 0.28) or diffusion capacity (DLCO, p = 0.45) or in exercise tolerance testing. However, symptoms of cough significantly improved in 58% (compared to 17% in controls) and dyspnea improved in 26% after ICS treatment (compared to 0 in controls). Symptoms of cough were improved in patients with a lower baseline FEV1 and FEV1/FVC ratio. Subgroup analysis showed significant lung function response in cases with lower baseline FEV1/FVC and higher residual volume (RV). CONCLUSION: Although FVC and DLCO did not improve in the ICS treated group, we saw no difference in decline compared to matched controls. Symptoms of dyspnea and cough improved with ICS especially in those with obstruction and air trapping suggesting that these should be considered an indication of ICS use in CBD patients. PMID- 29453141 TI - DFT/TD-DFT calculations, spectroscopic characterizations (FTIR, NMR, UV-vis), molecular docking and enzyme inhibition study of 7-benzoyloxycoumarin. AB - The quantum chemical study, spectroscopic characterization and biological activity of the pharmaceutically active 7-benzoyloxycoumarin (2) molecule have been presented. Potential energy surface (PES) scanning has been performed to search for the most stable molecular geometry of the present compound. The stable geometry in the ground state, IR, UV-Vis absorption and NMR (13C, 1H) spectra of the title compound were theoretically obtained and compared with the experimental one. Various theoretical molecular parameters like molecular energy, atomic charges, dipole moment, thermodynamic parameters, donor-acceptor natural bond orbital (NBO) hyperconjugative interaction energies, frontier molecular orbitals energies, HOMO-LUMO gap, molecular electrostatic potential, chemical reactivity descriptors, molecular polarizability and non-linear optical (NLO) properties are presented. Moreover, the 3D Hirshfeld surfaces and the associated 2D fingerprint plots have been explored. The percentages of various non-covalent interactions are studied and pictorialized by fingerprint plots of Hirshfeld surface. 7 Benzoyloxycoumarin has shown promising inhibitory activity against butrylcholinesterase (BuChE) as compared to the reference drug, galantamine. Molecular docking is carried to introduce compound into the X-ray crystal structures of butrylcholinesterase at the active site to find out the probable binding mode. The results of molecular docking indicated that 7-benzoyloxy derivative of coumarin may show enzyme inhibitor activity. PMID- 29453142 TI - Impulsivity related personality traits and cigarette smoking in adults: A meta analysis using the UPPS-P model of impulsivity and reward sensitivity. AB - BACKGROUND: Although there is considerable evidence of an association between impulsivity and cigarette smoking, the magnitude of this association varies across studies. Impulsivity comprises several discrete traits that may influence cigarette use in different ways. The present meta-analysis aims to examine the direction and magnitude of relationships between specific impulsivity-related traits, namely lack of premeditation, lack of perseverance, sensation seeking, negative urgency, positive urgency and reward sensitivity and both smoking status and severity of nicotine dependence in adults across studies and to delineate differences in effects across these relationships. METHODS: Ninety-seven studies were meta-analysed using random-effects models to examine the relationship between impulsivity-related traits and smoking status and severity of nicotine dependence. A number of demographic and methodological variables were also assessed as potential moderators. RESULTS: Smoking status and severity of nicotine dependence were significantly associated with all impulsivity-related traits except reward sensitivity. Lack of premeditation and positive urgency showed the largest associations with smoking status (r = 0.20, r = 0.24 respectively), while positive urgency showed the largest association with severity of nicotine dependence (r = 0.23). Study design moderated associations between lack of premeditation and lack of perseverance and smoking status, with larger effects found in cross-sectional compared to prospective studies. CONCLUSIONS: Finding suggest that impulsivity is associated with an increased likelihood of being a smoker and greater nicotine dependence. Specific impulsivity-related traits differentially relate to smoking status and severity of nicotine dependence. Understanding the complexity of impulsivity-related traits in relation to smoking can help to identify potential smokers and could inform cessation treatment. PMID- 29453143 TI - Structure and physico-mechanical properties of low temperature plasma treated electrospun nanofibrous scaffolds examined with atomic force microscopy. AB - Electrospun nanofibrous scaffolds are willingly used in tissue engineering applications due to their tunable mechanical, chemical and physical properties. Additionally, their complex openworked architecture is similar to the native extracellular matrix of living tissue. After implantation such scaffolds should provide sufficient mechanical support for cells. Moreover, it is of crucial importance to ensure sterility and hydrophilicity of the scaffold. For this purpose, a low temperature surface plasma treatment can be applied. In this paper, we report physico-mechanical evaluation of stiffness and adhesive properties of electrospun mats after their exposition to low temperature plasma. Complex morphological and mechanical studies performed with an atomic force microscope were followed by scanning electron microscope imaging and a wettability assessment. The results suggest that plasma treatment can be a useful method for the modification of the surface of polymeric scaffolds in a desirable manner. Plasma treatment improves wettability of the polymeric mats without changing their morphology. PMID- 29453144 TI - Polydipsia and anxiety as early warning signs of relapse in schizophrenia. PMID- 29453145 TI - Demographic and clinical characteristics associated with a history of bizarre delusions in a cross-diagnostic sample of individuals with psychotic disorders. AB - Bizarre delusions (BizD) are not specific to schizophrenia (SZ) and can be found in other psychotic disorders. However, to date, there are no studies investigating socio-demographic and clinical characteristics associated with BizD across the psychosis spectrum. In this study 819 subjects with a diagnosis of SZ (n = 250), schizoaffective disorder (SZA) (n = 228) and bipolar I disorder (BD) (n = 341) were included. Patients with history of BizD and with no BizD were compared with respect to socidemographic and clinical variables, and predictors of BizD were explored. Patients with BizD were less educated, less likely to be married, had higher Positive and Negative Syndrome Scale (PANSS) negative scores and lower Young Mania Rating Scale scores. Younger age, SZ and SZA diagnoses, higher PANSS positive scores, presence of reference delusions, tactile and olfactory hallucinations were predictors. Our results indicate that BizD are associated with higher illness severity, lower functionality and specific set of symptoms. PMID- 29453146 TI - Cannabis induced koro in a Nepali migrant.

PMID- 29453155 TI - Evaluation of the triage performed by registered nurses in the Hospital Clinico Universitario "Lozano Blesa" Emergency service (Saragossa, Spain). AB - OBJECTIVE: To evaluate nurses' triage quality and adequacy in Saragossa's Hospital Clinico and to compare the main characteristics of "urgent" and "non urgent" visits to the Hospital Emergency Department (HED). METHOD: This exploratory-retrospective research study was carried out over the last 3 months of 2015 (paediatrics, gynaecological and ophthalmologic emergencies were excluded). Data were obtained from the "Puesto Clinico Hospitalario" programme used in the HED. The quality of the triage performed by nurses was assessed using the 4 indexes proposed by Gomez Jimenez and the adequacy of patient classification was established by relating the level of triage assigned with the place of care, length of stay in the HED and type of discharge. Differences between "non-urgent" (seen in outpatient consultations of the HED) and "urgent" visits were analysed, RESULTS: 22,047 individuals were included. Quality indices relating to waiting times were not fully met. Higher severity of triage was associated with being attended in the area of Vital and Medical Care, a longer stay in the HED and a higher proportion of hospital admissions (p<.001), so that triage performed by nursing is considered adequate. "Non-urgent" visits obtained less severity of triage, a shorter stay in HED and a greater proportion of hospital discharges (p<.001). CONCLUSIONS: Nursing triage needs to improve quality aspects related to waiting times but is appropriate enough as it discriminates between place of care and type of discharge for each level of triage within the desirable limits. PMID- 29453154 TI - Unique pharmacology of a novel allosteric agonist/sensitizer insulin receptor monoclonal antibody. AB - OBJECTIVE: Insulin resistance is a key feature of Type 2 Diabetes (T2D), and improving insulin sensitivity is important for disease management. Allosteric modulation of the insulin receptor (IR) with monoclonal antibodies (mAbs) can enhance insulin sensitivity and restore glycemic control in animal models of T2D. METHODS: A novel human mAb, IRAB-A, was identified by phage screening using competition binding and surface plasmon resonance assays with the IR extracellular domain. Cell based assays demonstrated agonist and sensitizer effects of IRAB-A on IR and Akt phosphorylation, as well as glucose uptake. Lean and diet-induced obese mice were used to characterize single-dose in vivo pharmacological effects of IRAB-A; multiple-dose IRAB-A effects were tested in obese mice. RESULTS: In vitro studies indicate that IRAB-A exhibits sensitizer and agonist properties distinct from insulin on the IR and is translated to downstream signaling and function; IRAB-A bound specifically and allosterically to the IR and stabilized insulin binding. A single dose of IRAB-A given to lean mice rapidly reduced fed blood glucose for approximately 2 weeks, with concomitant reduced insulin levels suggesting improved insulin sensitivity. Phosphorylated IR (pIR) from skeletal muscle and liver were increased by IRAB-A; however, phosphorylated Akt (pAkt) levels were only elevated in skeletal muscle and not liver vs. control; immunochemistry analysis (IHC) confirmed the long lived persistence of IRAB-A in skeletal muscle and liver. Studies in diet-induced obese (DIO) mice with IRAB-A reduced fed blood glucose and insulinemia yet impaired glucose tolerance and led to protracted insulinemia during a meal challenge. CONCLUSION: Collectively, the data suggest IRAB-A acts allosterically on the insulin receptor acting non-competitively with insulin to both activate the receptor and enhance insulin signaling. While IRAB-A produced a decrease in blood glucose in lean mice, the data in DIO mice indicated an exacerbation of insulin resistance; these data were unexpected and suggested the interplay of complex unknown pharmacology. Taken together, this work suggests that IRAB-A may be an important tool to explore insulin receptor signaling and pharmacology. PMID- 29453156 TI - Approaching the experience of people through the process of a colostomy. AB - OBJECTIVE: The purpose of this paper is to explore the experience of people who go through the process of a colostomy. METHOD: Methodological approach of qualitative type and with a phenomenological framework, through in-depth interviews. Six women and 12 men, between 38 and 86 years of age, were interviewed before and after surgery, between 3 and 6 months after the intervention. The discourses were recorded and transcribed verbatim and analyzed following the 3 stages of Taylor and Bogdan: finding in progress, data coding and refinement of the understanding of the subject of study, and relativisation of the findings. RESULTS: Colon cancer and colostomy involve changes in a person's experience of privacy, and the connotations of "stigma" that can be attached to this vital element. It has been observed that the perception of deteriorated body image does not relate to an individual's gender, but rather to their age, work situation, type of work and social and cultural context. CONCLUSIONS: The reconstruction of an individual's relationship map, as a strategy for adapting to the process, is interrelated with social, cultural, and stoma management factors, and with their capacity for effective problem solving. PMID- 29453157 TI - [The Spanish Society of Paediatric Infectious Diseases guidelines on the prevention, diagnosis and treatment of neonatal herpes simplex infections]. AB - Neonatal herpes simplex virus infections are rare, but are associated with significant morbidity and mortality. Most newborns acquire herpes simplex virus infection in the peripartum period. For peripartum transmission to occur, women must be shedding the virus in their genital tracts symptomatically or asymptomatically around the time of delivery. There are evidence-based interventions in pregnancy to prevent the transmission to the newborn. Caesarean section should be performed in the presence of herpetic lesions, and antiviral prophylaxis in the last weeks of pregnancy is recommended to suppress genital tract herpes simplex virus at the time of delivery. The diagnosis and early treatment of neonatal herpes simplex virus infections require a high index of suspicion, especially in the absence of skin lesions. It is recommended to rule out herpes simplex virus infections in those newborns with mucocutaneous lesions, central nervous system involvement, or septic appearance. The prognosis of newborns with skin, eye, and/or mouth disease in the high-dose acyclovir era is very good. Antiviral treatment not only improves mortality rates in disseminated and central nervous system disease, but also improves the rates of long-term neurodevelopmental impairment in the cases of disseminated disease. Interestingly, a 6-month suppressive course of oral acyclovir following the acute infection has improved the neurodevelopmental prognosis in patients with CNS involvement. PMID- 29453158 TI - Female perpetrated sexual offences reported to a London sexual assault referral centre. AB - A gender specific approach to understanding female sex offenders is important for developing prevention and treatment strategies, yet research to date is limited. While it is recognised that females often offend with another person, there has been little attempt to look beyond the two groupings of solo and co-offending and study females who offend in larger groups. Furthermore, very few studies have looked at the victims of these crimes and all of these have focussed on child victims only. The present work describes demographic and assault related characteristics of victims of all ages reporting a sexual assault by a female perpetrator to the Havens sexual assault referral centres in London, UK, in a five year period, with the aim of identifying victim, perpetrator and offence patterns in solo, pair and group sexual assaults. 47 cases were identified, just 0.66% of the total cases seen, and victims ranged from 3 to 59 years of age. Female perpetrators actively participated in the sexual and physical violence in many cases and were often involved in other ways, such as facilitating the offence, procuring the victim and filming the assault. Victims of solo perpetrators were mostly children who reported an assault by a teacher or childminder. Victims of pairs were older and all perpetrators were male/female pairs, usually reportedly in a romantic relationship. Victims of groups were more often strangers to the perpetrators and these assaults were often very violent. These findings are discussed in relation to current knowledge and suggestions are made for further research. PMID- 29453159 TI - Identifying the most significant indicators of the total road safety performance index. AB - The review of the national and international literature dealing with the assessment of the road safety level has shown great efforts of the authors who tried to define the methodology for calculating the composite road safety index on a territory (region, state, etc.). The procedure for obtaining a road safety composite index of an area has been largely harmonized. The question that has not been fully resolved yet concerns the selection of indicators. There is a wide range of road safety indicators used to show a road safety situation on a territory. Road safety performance index (RSPI) obtained on the basis of a larger number of safety performance indicators (SPIs) enable decision makers to more precisely define the earlier goal- oriented actions. However, recording a broader comprehensive set of SPIs helps identify the strengths and weaknesses of a country's road safety system. Providing high quality national and international databases that would include comparable SPIs seems to be difficult since a larger number of countries dispose of a small number of identical indicators available for use. Therefore, there is a need for calculating a road safety performance index with a limited number of indicators (RSPIlnn) which will provide a comparison of a sufficient quality, of as many countries as possible. The application of the Data Envelopment Analysis (DEA) method and correlative analysis has helped to check if the RSPIlnn is likely to be of sufficient quality. A strong correlation between the RSPIlnn and the RSPI has been identified using the proposed methodology. Based on this, the most contributing indicators and methodologies for gradual monitoring of SPIs, have been defined for each country analyzed. The indicator monitoring phases in the analyzed countries have been defined in the following way: Phase 1- the indicators relating to alcohol, speed and protective systems; Phase 2- the indicators relating to roads and Phase 3- the indicators relating to trauma management. This will help achieve the standardization of indicators including data collection procedures and selection of the key list of indicators that need to be monitored. Based on the results, it has been concluded that the use of the most contributing indicators will make it possible to assess the level of road safety on a territory, with an acceptable quality score by focusing on the low-ranked countries. A smaller set of significant indicators defined in this manner can serve for a fast and simple understanding of a road safety situation and assessment of effects of measures undertaken. Also, this universal index approach is applicable in cases when a broader comprehensive set of indicators is analyzed, which provides a more accurate identification of weaker points and rank the countries in a more meaningful way. PMID- 29453160 TI - DNA damage and micronuclei in parthenogenetic and bisexual Darevskia rock lizards from the areas with different levels of soil pollution. AB - Natural species are widely used as indicator organisms to estimate of the impact of environmental pollution. Here we present the results of first study of a reliability of parthenogenetic Darevskia armeniaca and bisexual Darevskia raddei rock lizards as sentinels for monitoring of environmental genotoxicity. The comet assay and micronucleus test were applied to the lizards sampled in six areas in Armenia and Artsakh with different levels of soil contamination. The results obtained showed a clear relationship between the pollution level of lizards' habitats and the frequency of DNA damage in the comet assay. Low baseline frequency of micronuclei in D. armeniaca and D. raddei, however, makes this parameter ineffective for environmental genotoxicity evaluation. The parthenogenetic lizards D. armeniaca showed higher sensitivity toward genotoxic pollutions compared with bisexual D. raddei living in the same environment. The correlations between soil content of heavy metals Cr, Cu, Zn, Mo, Pb and DNA damage in D. armeniaca and between Cu, As, Mo, Pb and DNA damage in D. raddei were revealed. Overall, the lizards D. raddei and D. armeniaca appeared to be sensitive species in detecting soil pollution in natural environment. The application of the comet assay in Darevskia lizard species can be considered as a more appropriate method than a micronucleus test. The use of parthenogenetic lizards D. armeniaca as bioindicator will permit to assess the environmental genotoxicity independent of the genetic polymorphism of bisexual species. PMID- 29453161 TI - Gamma irradiation during gametogenesis in young adult zebrafish causes persistent genotoxicity and adverse reproductive effects. AB - The biological effects of gamma radiation may exert damage beyond that of the individual through its deleterious effects on reproductive function. Impaired reproductive performance can result in reduced population size over consecutive generations. In a continued effort to investigate reproductive and heritable effects of ionizing radiation, we recently demonstrated adverse effects and genomic instability in progeny of parents exposed to gamma radiation. In the present study, genotoxicity and effects on the reproduction following subchronic exposure during a gametogenesis cycle to 60Co gamma radiation (27 days, 8.7 and 53 mGy/h, total doses 5.2 and 31 Gy) were investigated in the adult wild-type zebrafish (Danio rerio). A significant reduction in embryo production was observed one month after exposure in the 53 mGy/h exposure group compared to control and 8.7 mGy/h. One year later, embryo production was significantly lower in the 53 mGy/h group compared only to control, with observed sterility, accompanied by a regression of reproductive organs in 100% of the fish 1.5 years after exposure. Histopathological examinations revealed no significant changes in the testis in the 8.7 mGy/h group, while in 62.5% of females exposed to this dose rate the oogenesis was found to be only at the early previtellogenic stage. The DNA damage determined in whole blood, 1.5 years after irradiation, using a high throughput Comet assay, was significantly higher in the exposed groups (1.2 and 3 fold increase in 8.7 and 53 mGy/h females respectively; 3-fold and 2-fold increase in 8.7 and 53 mGy/h males respectively) compared to controls. A significantly higher number of micronuclei (4-5%) was found in erythrocytes of both the 8.7 and 53 mGy/h fish compared to controls. This study shows that gamma radiation at a dose rate of >= 8.7 mGy/h during gametogenesis causes adverse reproductive effects and persistent genotoxicity (DNA damage and increased micronuclei) in adult zebrafish. PMID- 29453162 TI - The effect of cadmium exposure on diversity of intestinal microbial community of Rana chensinensis tadpoles. AB - Cadmium is a natural and widely distributed toxicant, and can be commonly found in environment. Intestinal microbiota plays a very important role in maintaining its host's health. The effects of cadmium on the intestinal microbiota composition and stability of amphibians are little known. We exposed Rana chensinensis (R. chensinensis) embryos to different concentrations of cadmium (0, 112 and 448 MUg Cd L-1) until they reached Gosner stage 38, and analyzed their microbial communities using 16S rRNA amplicon sequencing. By measures of both alpha and beta diversity, intestinal microbial communities were significantly differentiated in 448 MUg Cd L-1 exposure groups. Cadmium exposure significantly altered the intestinal microflora diversity and composition of R. chensinensis. At the phylum level, it is worth noting that Fusobacteria and Spirochaetae were not detected in 448 MUg Cd L-1 exposure groups. Firmicutes rapidly decreased in 448 MUg Cd L-1 exposure group. At the genus level, Succinispira (Firmicutes), Desulfovibrio (Proteobacteria) and Fusobacterium (Fusobacteria) vanished in 448 MUg Cd L-1 exposure groups. Our results demonstrate that cadmium exposure changed the composition and decreased the community diversity of intestinal microbiota of R. chensinensis tadpoles. Our study may provide a new framework based on intestinal microbiota to evaluate the response of amphibians to environmental chemicals pollution. PMID- 29453164 TI - Perforated Giant Meckel Diverticulitis in an elderly patient: Case report and review of the literature. AB - INTRODUCTION: Giant Meckel's diverticula are a relatively rare form of Meckel's, and henceforth their natural history is not clearly defined. They're currently thought of as an infrequent form of ileal dysgenesis. Noted complications include perforation, torsion and bowel obstruction. A much rarer presentation is Giant Meckel's diverticulitis. CASE: A 71 year old white female presented herself to the Emergency Department of a small urban community hospital, complaining of severe abdominal pain, nausea & vomiting. Her preoperative workup was consistent with Giant Meckel's diverticulitis, with evidence for perforation. She was taken for a laparotomy, which confirmed the diagnosis, and was treated with a small bowel resection. She made an otherwise uncomplicated recovery. CONCLUSION: Giant Meckel's diverticula and their complications require a high index of suspicion and once diagnosed, they should be managed expeditiously to avoid complications.

AB - INTRODUCTION: Persistent Mullerian Duct Syndrome (PMDS) is a rare sexual disease. It is characterized by the presence of female reproductive structures such as uterus, cervix, fallopian tubes and upper part of vagina in a normal genotypically and phenotypically male. The diagnosis is usually incidental since the patients will present with normal external genitalia and secondary sexual characteristics. Imaging techniques such as magnetic resonance imaging (MRI), computed tomography (CT) scan, or ultrasound (US) could help in the diagnosis. CASE PRESENTATION: A 45-year-old male presented with bilateral undescended testes since birth and 2 months history abdominal mass. CT scan showed a 13 * 17 * 20 cm solid pelvi-abdominal mass. The diagnosis of mixed germ cell tumor of the undescended testes was made based on the CT scan. During resection of the tumor, patient was found to have a uterus, fallopian tubes and ovaries. DISCUSSION: Pathological investigation showed endometrial tissues with portion of lower uterine segment and cervix with remnant of testes with marked atrophy. No Ovarian tissues were found nor fallopian tube as well. The diagnosis of PMDS was made based on the pathological report. CONCLUSION: PMDS is a challenging condition to diagnose. Radiological investigation can miss the presence of the Mullerian duct structures as in our case because of the unusual presentation of this condition. Early diagnosis and management is important as the malignant transformation is high due to the undescended testes.

AB - INTRODUCTION: Preoperative diagnosis of gastric cancer invasion is not always sufficiently accurate. Diagnostic endoscopic submucosal dissection (ESD) can be performed for the purpose of accurate decision making and to avoid partial treatment vs aggressive over-treatment. We present a patient with the gastric cancer with indeterminate pre-operative diagnosis for depth of the invasion. CASE PRESENTATION: A 70-year-old man presented at our hospital because both anti Helicobacter pylori (Hp) IGG antibody and serum pepsinogen (PG) levels were classified as positive. Upper gastrointestinal endoscopy was performed, and a large (3.5 cm) pedunculated polyp-shaped gastric cancer with prolapse into the duodenal bulb was found. [fluorine-18]-fluorodeoxy-glucose (18F-FDG)-positron emission tomography (PET)/computed tomography (CT) imaging showed high 18F-FDG uptake, suggesting the possibility of advanced gastric cancer. Since the pre operative diagnosis of the cancer invasion was indeterminable, diagnostic ESD was performed. The pathohistological diagnosis was early gastric cancer (33 * 35 * 20 mm, well differentiated tubular adenocarcinoma [tub1], pT1a[M], ly[--], v[--], UL[--], pHM0, pVM0) according to the Japanese classification of gastric carcinoma. DISCUSSION AND CONCLUSION: It was reported that ESD for early gastric cancers that met the expanded criteria was acceptable and should be the standard treatment instead of gastrectomy. The expanded criteria included cancer confined to the mucosa (cT1a), a single primary intestinal-type gastric adenocarcinoma, an ulcer-negative lesion of any size. We reported a case of pedunculated gastric cancer with prolapse into the duodenal bulb that could be treated by ESD. The present case is a good example of diagnostic ESD being used to minimize the damage of gastric cancer treatment. PMID- 29453166 TI - Skull metastasis revealing a renal tumor: A case report and review of the literature. AB - BACKGROUND: Renal cell carcinomas represent 85% of malignant renal tumors. Typically, the tumor remains asymptomatic a long time before the appearance of urologic clinical signs. In some cases, metastasis can precede the manifestations of the primary tumor. Different sites are potential metastatic localizations for renal tumors, including skull metastases who represent a very rare location. CASE DESCRIPTION: We report the case of a 65-year-old man presented after the appearance of a skull mass. This tumefaction developed and had progressively grown up during 9 months. Neurological examination was normal. Brain imaging showed a soft tissue lesion in the left parietal bone with marked osteolysis. Peroperative was found a huge oval-shape hemorrhagic and firm mass associated with scalp invasion and bone destruction that was totally resected. Histopathology revealed renal cell carcinoma (RCC). Pelvic and abdominal CT scan was performed, revealing a large mass on the left kidney with irregular contours and poor definition. The patient was then transferred to urology where he underwent nephrectomy. The patient went then through adjuvant chemotherapy. Clinical and radiological follow up of 12 months did not bring to light tumor recurrence. CONCLUSIONS: Although metastases to the head and neck occur infrequently, they should be considered when evaluating any unusual subcutaneous mass in the head and neck. RCC should not be discounted when sites as unlikely as the calvaria are evaluated. Treatment of metastatic renal cell carcinoma is complex, and the optimal regimen for achieving a lasting response without severe toxicity has not yet been defined. PMID- 29453167 TI - Electrochemical detection of methylated DNA on a microfluidic chip with nanoelectrokinetic pre-concentration. AB - DNA methylation is considered to be a promising marker for the early diagnosis and prognosis of cancer. However, direct detection of the methylated DNAs in clinically relevant samples is still challenging because of its extremely low concentration (~fM). Here, an integrated microfluidic chip is reported, which is capable of pre-concentrating the methylated DNAs using ion concentration polarization (ICP) and electrochemically detecting the pre-concentrated DNAs on a single chip. The proposed chip is the first demonstration of an electrochemical detection of both level and concentration of the methylated DNAs by integrating a DNA pre-concentration unit without gene amplification. Using the proposed chip, 500 fM to 500 nM of methylated DNAs is pre-concentrated by almost 100-fold in 10 min, resulting in a drastic improvement of the electrochemical detection threshold down to the fM level. The proposed chip is able to measure not only the DNA concentration, but also the level of methylation using human urine sample by performing a consecutive electrochemical sensing on a chip. For clinical application, the level as well as the concentration of methylation of glutathione S transferase-P1 (GSTP1) and EGF-containing fibulin-like extracellular matrix protein 1 (EFEMP1), which are known to be closely associated with prostate cancer diagnosis, are electrochemically detected in human urine spiked with these genes. The developed chip shows a limit of detection (LoD) of 7.9 pM for GSTP1 and 11.8 pM for EFEMP1 and is able to detect the level of methylation in a wide range from 10% to 100% with the concentration variation from 50 pM to 500 nM.

AB - INTRODUCTION: Road traffic injuries (RTIs) are considered as one of the most important health problems endangering people's life. The examination of the geographical distribution of RTIs could help policymakers in better planning to reduce RTIs. This study, therefore, aimed to determine the spatial-temporal clustering of mortality from RTIs in West of Iran. METHODS: Deaths from RTIs, registered in Forensic Medicine Organization of Kermanshah province over a period of six years (2009-2014), were used. Using negative binomial regression, the mortality trend was investigated. In order to investigate the spatial distribution of RTIs, we used ArcGIS. (Version 10.3). RESULTS: The median age of the 3231 people died in RTIs was 37 (IQR = 31) year, 78.4% were male. The 6-year average mortality rate from RTIs was 27.8/100,000 deaths, and the average rate had a declining trend. The dispersion of RTIs showed that most deaths occurred in Kermanshah, Islamabad, Bisotun, and Harsin road axes, respectively. The mean center of all deaths from RTIs occurred in Kermanshah province, the central area of Kermanshah district. The spatial trend of such deaths has moved to the northeast-southwest, and such deaths were geographically centralized. Results of Moran's I with respect to cluster analysis also indicated positive spatial autocorrelations. CONCLUSION: The results showed that the mortality rate from RTIs, despite the decline in recent years, is still high when compared with other countries. The clustering of accidents raises the concern that road infrastructure in certain locations may also be a factor. Regarding the results related to the temporal analysis, it is suggested that the enforcement of traffic rules be stricter at rush hours. PMID- 29453169 TI - Randomized EEG functional brain networks in major depressive disorders with greater resilience and lower rich-club coefficient. AB - OBJECTIVE: Some studies have shown that the functional electroencephalogram (EEG) and functional magnetic resonance imaging (fMRI) networks in those with major depressive disorders (MDDs) have an abnormal random topology. In this study we aimed to further investigate the characteristics of the randomized functional brain networks in MDDs by examining resting-state scalp-EEG data. METHODS: Based on the methods of independent component analysis (ICA) and graph theoretic analysis, the abnormalities in the power spectral density (PSD) functional brain networks were compared between 13 MDDs and 13 matched healthy controls (HCs). Nonparametric permutation tests were performed to explore the between-group differences in multiple network metrics. The Pearson correlation coefficients were calculated to measure the linear relationships between the clinical symptom and network metrics. RESULTS: Compared with the HCs, the MDDs showed significant randomization of global network metrics, characterized by greater global efficiency, but lower clustering coefficient, characteristic path length, and local efficiency. This randomization was also reflected in the less heterogeneous and less fat-tailed degree distributions in the MDDs. More importantly, the randomized brain networks in MDDs had greater network resilience to both random failure and targeted attack, which might be a protective mechanism to avoid fast deterioration of the integrity of MDDs' brain networks under pathological attack. In addition, the randomized brain networks in MDDs had a lower level of rich-club coefficient, suggesting that the density of connections among rich-club hubs became sparser. Furthermore, some of the network metrics explored in this study were significantly associated with the severity of depression in all participants. CONCLUSIONS: A replicable randomization of the brain network is found in MDDs. The randomization is further characterized by more homogeneous degree distribution, greater resilience and lower rich-club coefficient, reflecting the reconfiguration of the brain network caused by the reduction of hub nodes in MDD. SIGNIFICANCE: Our results may provide new biomarkers of brain network organization in MDD. PMID- 29453170 TI - Symmetry of cortical planning for initiating stepping in sub-acute stroke. AB - OBJECTIVE: This study examined motor planning for stepping when the paretic leg was either stepping or standing (to step with the non-paretic leg), to understand whether difficulty with balance and walking post-stroke could be attributed to poor motor planning. METHODS: Individuals with stroke performed self-initiated stepping. Amplitude and duration of the movement-related cortical potential (MRCP) was measured from Cz. Electromyography (EMG) of biceps femoris (BF) and rectus femoris (RF) were collected. RESULTS: There were no differences between legs in stepping speed, MRCP or EMG parameters. The MRCPs when stepping with the paretic leg and the non-paretic leg were correlated. When the paretic leg was stepping, the MRCP amplitude correlated with MRCP duration, indicating a longer planning time was accompanied by higher cognitive effort. Slow steppers had larger MRCP amplitudes stepping with the paretic leg and longer MRCP durations stepping with the non-paretic leg. CONCLUSIONS: MRCP measures suggest that motor planning for initiating stepping are similar regardless of which limb is stepping. Individuals who stepped slowly had greater MRCP amplitudes and durations for planning. SIGNIFICANCE: Individuals who step slowly may require more time and effort to plan a movement, which may compromise their safety in the community. PMID- 29453171 TI - Finger strength, individuation, and their interaction: Relationship to hand function and corticospinal tract injury after stroke. AB - OBJECTIVE: The goal of this study was to determine the relative contributions of finger weakness and reduced finger individuation to reduced hand function after stroke, and their association with corticospinal tract (CST) injury. METHODS: We measured individuated and synergistic maximum voluntary contractions (MVCs) of the index and middle fingers, in both flexion and extension, of 26 individuals with a chronic stroke using a robotic exoskeleton. We quantified finger strength and individuation, and defined a novel metric that combines them - "multifinger capacity". We used stepwise linear regression to identify which measure best predicted hand function (Box and Blocks Test, Nine Hole Peg Test) and arm impairment (the Upper Extremity Fugl-Meyer Test). RESULTS: Compared to metrics of strength or individuation, capacity survived the stepwise regression as the strongest predictor of hand function and arm impairment. Capacity was also most strongly related to presence or absence of lesion overlap with the CST. CONCLUSIONS: Reduced strength and individuation combine to shrink the space of achievable finger torques, and it is the resulting size of this space - the multifinger capacity - that is of elevated importance for predicting loss of hand function. SIGNIFICANCE: Multi-finger capacity may be an important target for rehabilitative hand training. PMID- 29453172 TI - The conversion of biomass to light olefins on Fe-modified ZSM-5 catalyst: Effect of pyrolysis parameters. AB - Light olefins are the key building blocks for the petrochemical industry. In this study, the effects of in-situ and ex-situ process, temperature, Fe loading, catalyst to feed ratio and gas flow rate on the olefins carbon yield and selectivity were explored. The results showed that Fe-modified ZSM-5 catalyst increased the olefins yield significantly, and the ex-situ process was much better than in-situ. With the increasing of temperature, Fe-loading amount, catalyst to feed ratio, and gas flow rate, the carbon yields of light olefins were firstly increased and further decreased. The maximum carbon yield of light olefins (6.98% C-mol) was obtained at the pyrolysis temperature of 600 degrees C, catalyst to feed ratio of 2, gas flow rate of 100ml/min, and 3wt% Fe/ZSM-5 for cellulose. The selectivity of C2H4 was more than 60% for all feedstock, and the total light olefins followed the decreasing order of cellulose, corn stalk, hemicelluloses and lignin. PMID- 29453173 TI - Land use change impacts on the amount and quality of recharge water in the loess tablelands of China. AB - Exploring how land use change (LUC) influences the amount and quality of recharge water is important for groundwater sustainability and land use planning. With loess of up to 200m in thickness and unsaturated zones up to 100m below the surface, the loess tablelands in China can store abundant groundwater resources. However, groundwater depletion and substantial LUC have been simultaneously observed. It is thus necessary to investigate the relationship between LUC and groundwater. We sampled 10-m soil profiles for three land use types (farmlands, apple orchards of 10 and 20years old). After measuring the chloride and nitrate concentration in soil pore water, the LUC effects on the amount and quality of recharge water quality were quantified based on the mass balance method. Results showed that soil moisture in aged (20-year-old) apple orchards was significantly reduced relative to that measured in farmlands and younger (10-year-old) orchards, where measured soil moistures were roughly equal. The accumulated nitrate-nitrogen and the depth below which nitrate is stable was smallest in farmlands, intermediate in 10-year-old apple orchards, and largest under 20-year old apple orchards. The diffuse recharge was 33.0+/-17.9mmyear-1, accounting for 7.3+/-1.8% of mean annual precipitation under farmlands; however, the conversion from farmlands to 20-year-old apple orchards reduced recharge by 42%. The nitrate infiltrating to groundwater annually was 4.9+/-2.9kghm-2 and 4.1+/-3.1kghm-2 under farmlands and 20-year-old apple orchards, respectively. The impacts of LUC over the past decades have not yet reached groundwater because of low recharge rates; further, the primary factor influencing groundwater quality is recharge rate rather than pollutant concentration. As such, the LUC from farmland to apple orchard has little impact on short-term groundwater recharge and quality; long term impact, however, may be significant. PMID- 29453174 TI - Antibiotic resistance along an urban river impacted by treated wastewaters. AB - Urban rivers are impacted ecosystems which may play an important role as reservoirs for antibiotic-resistant (AR) bacteria. The main objective of this study was to describe the prevalence of antibiotic resistance along a sewage polluted urban river. Seven sites along the Zenne River (Belgium) were selected to study the prevalence of AR Escherichia coli and freshwater bacteria over a 1 year period. Culture-dependent methods were used to estimate E. coli and heterotrophic bacteria resistant to amoxicillin, sulfamethoxazole, nalidixic acid and tetracycline. The concentrations of these four antibiotics have been quantified in the studied river. The antibiotic resistance genes (ARGs), sul1, sul2, tetW, tetO, blaTEM and qnrS were also quantified in both particle-attached (PAB) and free-living (FLB) bacteria. Our results showed an effect of treated wastewaters release on the spread of antibiotic resistance along the river. Although an increase in the abundance of both AR E. coli and resistant heterotrophic bacteria was observed from upstream to downstream sites, the differences were only significant for AR E. coli. A significant positive regression was also found between AR E. coli and resistant heterotrophic bacteria. The concentration of ARGs increased from upstream to downstream sites for both particle-attached (PAB) and free-living bacteria (FLB). Particularly, a significant increase in the abundance of four among six ARGs analyzed was observed after crossing urban area. Although concentrations of tetracycline significantly correlated with tetracycline resistance genes, the antibiotic levels were likely too low to explain this correlation. The analysis of ARGs in different fractions revealed a significantly higher abundance in PAB compared to FLB for tetO and sul2 genes. This study demonstrated that urban activities may increase the spread of antibiotic resistance even in an already impacted river. PMID- 29453175 TI - Solubilization of polycyclic aromatic hydrocarbons (PAHs) with phenol in coking wastewater treatment system: Interaction and engineering significance. AB - Polycyclic aromatic hydrocarbons (PAHs) are accumulated in the sludge collected from the coking wastewater treatment. Phenol with its efficient degradation observed in biological treatment promotes the solubility of PAHs in aqueous phase. The interaction mechanism of phenol and PAHs in aqueous and sludge phases was systematically studied in two full-scale engineering projects composed of anaerobic-oxic-oxic (A-O1-O2) and anaerobic-oxic-hydrolytic-oxic (A-O1-H-O2) sequences. The results showed that reasonable use of phenol facilitates solubilization of PAHs alleviating their emission problems. The DeltaPAHs/Deltaphenol mass ratio in the sludge phase of A-O1-H-O2 system (146.3) exceeded that in A-O1-O2 one (63.80), exhibiting a good solubilization effect on PAHs with their more efficient degradation in the former. The full-scale observations were verified in laboratory solubilization experiments using phenanthrene (Phen), pyrene (Pyr) and benzo[a]pyrene (Bap) as the models of 3-, 4 and 5-ring PAHs, respectively. The binding energies of [phenol-PAHs] complexes were calculated using computational density functional theory showing consistency with the experimentally observed phenol-facilitated solubilization efficiencies in the row of Phen>Pyr>Bap. The results showed the fate and distribution of PAHs in coking wastewater treatment affected by the presence of phenol serving as a cost effective reagent for enhanced solubilization of PAHs from the coking wastewater sludge. PMID- 29453176 TI - Toxicological interactions induced by chronic exposure to gold nanoparticles and microplastics mixtures in Daphnia magna. AB - The effects of emerging environmental contaminants on human and environmental health is of high concern, especially those potentially induced by mixtures. The main goal of the present study was to assess the chronic effects of mixtures of citrate stabilized ~5 nm gold nanoparticles (AuNP) and 1-5MUm microplastics (MP) on Daphnia magna. A 21-day bioassay was carried out. The effect criteria were parental mortality, somatic growth and several reproductive parameters. AuNP induced parental mortality, reduced the total offspring and caused immobile juveniles and aborted eggs. MP induced parental mortality, delayed the first brood release, decreased the number of broods released, the total offspring, and caused immobile juveniles. All the mixtures caused higher toxicity than AuNP and MP alone. Based on parental mortality, evidences of antagonism between AuNP and MP were observed at low concentrations of both mixture components, whereas evidences of synergism at high concentrations were found. Chronic (21-day) exposure of D. magna to AuNPs, MP, and their mixtures can impair development, reproduction, ultimately leading to death. PMID- 29453177 TI - Association of dioxin exposure and reproductive hormone levels in men living near the Bien Hoa airbase, Vietnam. AB - Dioxins are endocrine-disrupting chemicals, and their effects on reproductive functions are well-documented. The aim of the present study was to measure the levels of reproductive hormones in 42 men residing near a dioxin-contaminated area in Vietnam. We measured levels of 17 2,3,7,8-substituted congeners of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) and four non-ortho polychlorinated biphenyls (PCBs) in blood. Levels of follicle-stimulating hormone, luteinizing hormone, progesterone, prolactin, estradiol, and total testosterone were measured in serum. Blood dioxin levels were elevated; the levels of 2,3,7,8-tetrachlorodibenzo-p-dioxin was 7.3pg/g fat. Seven of the men had testosterone levels below 250ng/dL, and nine men had prolactin levels above 9.7ng/mL. Four PCDD congeners, two PCDF congeners, one PCB congener, and the sum TEQ of PCDDs, PCDDs/Fs, and PCDDs/Fs/PCBs were positively and significantly correlated with prolactin levels. Two PCDD congeners, six PCDF congeners, two PCB congeners, and the TEQs of PCDFs and PCBs were negatively and significantly correlated with testosterone levels. There were no significant correlations between dioxin congeners and follicle-stimulating hormone, luteinizing hormone, or progesterone levels. PMID- 29453178 TI - Seasonal dynamics of tetracycline resistance gene transport in the Sumas River agricultural watershed of British Columbia, Canada. AB - Environmental transport of contaminants that can influence the development of antibiotic resistance in bacteria is an important concern in the management of ecological and human health risks. Agricultural regions are locales where practices linked to food crop and livestock production can introduce contaminants that could alter the selective pressures for the development of antibiotic resistance in microbiota. This is important in regions where the use of animal manure or municipal biosolids as waste and/or fertilizer could influence selection for antibiotic resistance in pathogenic bacterial species. To investigate the environmental transport of contaminants that could lead to the development of antibiotic resistance in bacteria, a watershed with one of the highest levels of intensity of agricultural activity in Canada was studied; the Sumas River located 60 km east of Vancouver, British Columbia. This two-year assessment monitored four selected tetracycline resistance genes (tet(O), tet(M), tet(Q), tet(W)) and water quality parameters (temperature, specific conductivity, turbidity, suspended solids, nitrate, phosphate and chloride) at eight locations across the watershed. The tetracycline resistance genes (Tcr) abundances in the Sumas River network ranged between 1.47 * 102 and 3.49 * 104 copies/mL and ranged between 2.3 and 6.9 copies/mL in a control stream (located far from agricultural activities) for the duration of the study. Further, Tcr abundances that were detected in the wet season months ranged between 1.3 * 103 and 2.29 * 104 copies/mL compared with dry season months (ranging between 0.6 and 31.2 copies/mL). Highest transport rates between 1.67 * 1011 and 1.16 * 1012 copies/s were observed in November 2005 during periods of high rainfall. The study showed that elevated concentrations of antibiotic resistance genes in the order of 102 104 copies/mL can move through stream networks in an agricultural watershed but seasonal variations strongly influenced specific transport patterns of these genes. PMID- 29453179 TI - Enhanced Cr(VI) removal from acidic solutions using biochar modified by Fe3O4@SiO2-NH2 particles. AB - Fe3O4@SiO2-NH2 magnetic particles with core-shell structure were attached on carboxylated biochar derived from phoenix tree leaves to synthesize a novel magnetic biochar for removing Cr(VI) ions from acidic solutions. FSEM, FTEM, XRD characterizations of the synthesized magnetic biochar revealed that the Fe3O4@SiO2-NH2 magnetic particles distributed uniformly on the surface or macrospores of carboxylated biochar by strong chemical bonding. The Cr(VI) ions adsorption capacity of magnetic biochar was 27.2mg.g-1, surpassing original carboxylated biochar (18.2mg.g-1). VSM and XPS characterizations demonstrated that the attached Fe3O4@SiO2-NH2 magnetic particles not only endowed biochar with perfect magnetic property (23emu.g-1) but also provided complexing sites for binding Cr(III) cations reduced from Cr(VI) anions. The Cr(VI) ions removal by magnetic biochar contained three steps: (1) adsorption of Cr(VI) anions by protonated functional groups; (2) reduction of Cr(VI) anions to Cr(III) cations by electron-donor groups; and (3) chelation of Cr(III) cations by amine groups. The adsorption recycling test showed that magnetic biochar kept 85% of its initial Cr(VI) adsorption capacity at the sixth cycle, and the Fe leakage under pH1.0 was smaller than 0.25mg.L-1. The results indicated that this novel magnetic biochar was applicable for the practical treatment of Cr(VI)-containing wastewater. PMID- 29453180 TI - Study of the spatial and temporal distribution of accumulated solids in an experimental vertical-flow constructed wetland system. AB - Clogging is the most serious problem in the operation of subsurface flow constructed wetlands (SSF CWs) and is caused by the accumulation of solids in substrates. Study of the solids accumulation process can provide a more accurate reference for the management and maintenance of SSF CWs. In this study, an experimental vertical-flow constructed wetland system was recreated in the lab, and substrates with different depth were sampled through different operation time to reveal the spatial and temporal distribution of accumulated solids. During the study, particulates mainly accumulated through adsorption along the gravel surface. Therefore, the matrix could still provide sufficient space for the particles to pass through and be intercepted or adsorbed into the system at a constant rate. At the end of the study, an increasing number of large particles had been intercepted and were accumulated in the 0-2cm layer of the matrix, indicating a significant decrease in the pore diameter at the top substrate layer. The spatial and temporal accumulation of substrate particulates during the study period was accurately simulated by first-order kinetics models, and the simulated results were in good agreement with measured values. PMID- 29453181 TI - Fish consumption from urban impoundments: What are the health risks associated with DDTs and other organochlorine pesticides in fish to township residents of a major inland city. AB - Organochlorine pesticides (OCPs) in South Africa have for the most part been banned, except dichlorodiphenyltrichloroethane (DDT) which is still used as malaria vector control. The aim of this study was to determine OCP residues in the aquatic fauna of one of South Africa's most populated areas, Soweto. Risk to human health through OCP exposure via fish consumption was investigated. Clarias gariepinus was chosen as bioindicator because it is an apex predator that is in abundance, but is also a valued food source. Dichlorodiphenyltrichloroethanes (DDTs), hexachlorocyclohexanes (HCHs), and chlordanes (CHLs) were detected in the fish tissue with the DDTs being the most prevalent at all sites. Of the three locations, Fleurhof, Orlando, and Lenasia, the latter location's fish had the highest SigmaOCP load, ranging between 81 and 1190ng/gwm. The DDTs were determined to be from historic use, whereas the CHL levels indicated more recent inputs. Although the possibility of illegal use cannot be excluded completely, the presence of OCPs outside of their allowed areas of use indicate that these compounds not only stay in the aquatic systems long term, but may be of concern in areas previously not considered high risk areas. The OCP residues in C. gariepinus from the study area pose an extremely high risk to human health when consumed, and has a cancer risk as high as 1 in 10. This potential problem should be kept in consideration when developing national health and conservation strategies. PMID- 29453182 TI - Identification of microbial species present in a pesticide dissipation process in biobed systems using typical substrates from southeastern Mexico as a biomixture at a laboratory scale. AB - Biobed systems are an important option to control point pollution in agricultural areas. Substrates used and microbial diversity present in a biomixture perform an essential function in pesticide dissipation. In this study, the effects of soil (50% of volume/volume [V/V] proportion for all biomixtures) and four soil-based biomixtures (miniaturized biobeds; addition of novel substrates from southeastern Mexico) on dissipation of high concentrations of 2,4-dichlorophenoxyacetic acid (2,4-D), atrazine, carbofuran, diazinon, and glyphosate and on microbial diversity in biomixtures were evaluated. Small residual amounts of all pesticides at 20 (<2%) and 41 (<1%) days were observed; however, the lowest efficiency rates were observed in soil. Glyphosate was the only pesticide that completely dissipated in soil and biomixtures. Archaea, bacteria, and fungi were identified in biobeds, with bacteria being the most diverse microorganisms according to the identified species. The presence of white-rot fungi (normally related to pesticide degradation in biomixtures) was observed. Effects of the pesticide type and of biomixtures on pesticide dissipation were significant (P<0.05); however, only the effect of biomixtures on microbial diversity was significant (P<0.05); microbial diversity and richness had a significant effect on the residual amount of pesticides (P<0.05). Microbial diversity in terms of phyla was directly related to physicochemical parameters such as organic matter, lignin, water holding capacity, and pH of soil and biomixtures. PMID- 29453183 TI - Spatial assessment of land degradation through key ecosystem services: The role of globally available data. AB - Land degradation is a serious issue especially in dry and developing countries leading to ecosystem services (ESS) degradation due to soil functions' depletion. Reliably mapping land degradation spatial distribution is therefore important for policy decisions. The main objectives of this paper were to infer land degradation through ESS assessment and compare the modelling results obtained using different sets of data. We modelled important physical processes (sediment erosion and nutrient export) and the equivalent ecosystem services (sediment and nutrient retention) to infer land degradation in an area in the Ethiopian Great Rift Valley. To model soil erosion/retention capability, and nitrogen export/retention capability, two datasets were used: a 'global' dataset derived from existing global-coverage data and a hybrid dataset where global data were integrated with data from local surveys. The results showed that ESS assessments can be used to infer land degradation and identify priority areas for interventions. The comparison between the modelling results of the two different input datasets showed that caution is necessary if only global-coverage data are used at a local scale. In remote and data-poor areas, an approach that integrates global data with targeted local sampling campaigns might be a good compromise to use ecosystem services in decision-making. PMID- 29453184 TI - Is it photosensitization or photodegradation when UV-B irradiation is combined with BDE-47? Evidence from the growth and reproduction changes of rotifer Brachionus plicatilis. AB - Ecotoxicological methods were applied in the present study, and the marine rotifer Brachionus plicatilis was used as the toxic endpoint to depict what occurred when 2,2',4,4'-tetrabromodiphenyl ether (BDE-47) was combined with solar ultraviolet-B radiation (UV-B). B. plicatilis was exposed to three different combination methods of BDE-47 and UV-B at an equal toxicity ratio, including normal rotifer co-cultured with UV-B-irradiated BDE-47 (known as Method I), UV-B irradiated rotifer co-cultured with BDE-47 exposure (known as Method II) and normal rotifer co-cultured with the simultaneous addition of BDE-47 and UV-B irradiation (known as Method III). Acute and chronic experiments were preformed to determine the toxicity differentiation according to the growth and reproduction changes in the rotifer. Twenty-four-hour acute experiments showed that the modes of three combined methods changed from antagonism to additive, to synergistic with the concentration/dose increment, and the contribution rates of Method I and Method II to Method III were calculated by approximately 40.4% and 59.6%, respectively. Chronic exposure to either the single stressor or the combination of stressors inhibited the growth and reproduction of the rotifer, demonstrating the inhibition of the population growth rate and the decrease in the larvae production. Three combined groups presented more serious damages compared to groups with single stress exposure, and the ascending sequence of toxicity was Method I=4 drinks for women and >=5 drinks for men) among nontreatment-seeking young adults, but may not be optimized. Adaptive text message support could enhance effectiveness by assisting context-specific goal setting and striving, but it remains unknown how to best integrate it into text message interventions. OBJECTIVE: The objective of this study was to evaluate young adults' engagement with a text message intervention, Texting to Reduce Alcohol Consumption 2 (TRAC2), which focuses on reducing weekend alcohol consumption. TRAC2 incorporated preweekend drinking-limit goal-commitment ecological momentary assessments (EMA) tailored to past 2-week alcohol consumption, intraweekend goal reminders, self-efficacy EMA with support tailored to goal confidence, and maximum weekend alcohol consumption EMA with drinking limit goal feedback. METHODS: We enrolled 38 nontreatment-seeking young adults (aged 18 to 25 years) who screened positive for hazardous drinking in an urban emergency department. Following a 2-week text message assessment-only run-in, subjects were given the opportunity to enroll in 4-week intervention blocks. We examined patterns of EMA responses and voluntary re-enrollment. We then examined how goal commitment and goal self-efficacy related to event-level alcohol consumption. Finally, we examined the association of length of TRAC2 exposure with alcohol-related outcomes from baseline to 3-month follow-up. RESULTS: Among a diverse sample of young adults (56% [28/50] female, 54% [27/50] black, 32% [12/50] college enrolled), response rates to EMA queries were, on average, 82% for the first 4-week intervention block, 75% for the second 4-week block, and 73% for the third 4-week block. In the first 4 weeks of the intervention, drinking limit goal commitment was made 68/71 times it was prompted (96%). The percentage of subjects being prompted to commit to a drinking limit goal above the binge threshold was 52% (15/29) in week 1 and decreased to 0% (0/15) by week 4. Subjects met their goal 130/146 of the times a goal was committed to (89.0%). There were lower rates of goal success when subjects reported lower confidence (score <4) in meeting the goal (76% [32/42 weekends]) compared with that when subjects reported high confidence (98% [56/57 weekends]; P=.001). There were reductions in alcohol consumption from baseline to 3 months, but reductions were not different by length of intervention exposure. CONCLUSIONS: Preliminary evidence suggests that nontreatment-seeking young adults will engage with a text message intervention incorporating self-regulation support features, resulting in high rates of weekend drinking limit goal commitment and goal success.

PMID- 29453194 TI - Comparison of Generic Fluorescent Markers for Detection of Extracellular Vesicles by Flow Cytometry. AB - BACKGROUND: Extracellular vesicles (EVs) in biofluids are potential biomarkers of disease. To explore the clinical relevance of EVs, a specific generic EV marker would be useful, one that does not require antibodies and binds to all EVs. Here we evaluated 5 commonly used generic markers for flow cytometry. METHODS: Flow cytometry (A60-Micro, Apogee) was used to evaluate the ability of the generic EV markers calcein acetoxymethyl ester, calcein acetoxymethyl ester violet, carboxyfluorescein succinimidyl ester (CFSE), 4-(2-[6-(dioctylamino)-2 naphthalenyl]ethenyl)-1-(3-sulfopropyl)pyridinium (di-8-ANEPPS), and lactadherin to stain EVs from MCF7 human breast adenocarcinoma cell line-conditioned culture medium [epithelial cell adhesion molecule positive (EpCAM+)] or platelet EVs from human plasma [integrin beta3 positive (CD61+)]. Side scatter triggering was applied as a reference, and the influence of non-EV components (proteins and lipoproteins) was evaluated. RESULTS: Di-8-ANEPPS, lactadherin, and side scatter detected 100% of EpCAM+ MCF7 EVs. Lactadherin and side scatter detected 33% and 61% of CD61+ EVs, respectively. Di-8-ANEPPS detected platelet EVs only if soluble protein was first removed. Because all generic markers stained proteins, at best 33% of platelet EVs in plasma were detected. The calcein markers and CFSE were either insensitive to EVs in both samples or associated with swarm detection. CONCLUSIONS: None of the generic markers detected all and only EVs in plasma. Side scatter triggering detected the highest concentration of plasma EVs on our A60-Micro, followed by lactadherin. The choice between scatter or lactadherin primarily depends on the analytical sensitivity of the flow cytometer used. PMID- 29453195 TI - Mutation of IFNLR1, an interferon lambda receptor 1, is associated with autosomal dominant non-syndromic hearing loss. AB - Background Hereditary sensorineural hearing loss is a genetically heterogeneous disorder. Objectives This study was designed to explore the genetic etiology of deafness in a large Chinese family with autosomal dominant, nonsyndromic, progressive sensorineural hearing loss (ADNSHL). Methods Whole exome sequencing and linkage analysis were performed to identify pathogenic mutation. Inner ear expression of Ifnlr1 was investigated by immunostaining in mice. ifnlr1 Morpholino knockdown Zebrafish were constructed to explore the deafness mechanism. Results We identified a cosegregating heterozygous missense mutation, c.296G>A (p.Arg99His) in the gene encoding interferon lambda receptor 1 (IFNLR1) a protein that functions in the Jak/ STAT pathway- are associated with ADNSHL Morpholino knockdown of ifnlr1 leads to a significant decrease in hair cells and non-inflation of the swim bladder in late-stage zebrafish, which can be reversed by injection with normal Zebrafish ifnlr1 mRNA. Knockdown of ifnlr1 in zebrafish causes significant upregulation of cytokine receptor family member b4 (interleukin-10r2), jak1, tyrosine kinase 2, stat3, and stat5b in the Jak1/STAT3 pathway at the mRNA level. ConclusionIFNLR1 function is required in the auditory system and that IFNLR1 mutations are associated with ADNSHL. To the best of our knowledge, this is the first study implicating an interferon lambda receptor in auditory function. PMID- 29453196 TI - Genome-wide association study identifies ERBB4 on 2q34 as a novel locus associated with sperm motility in Japanese men. AB - BACKGROUND: The decrease in sperm motility has a potent influence on fertilisation. Sperm motility, represented as the percentage of motile sperm in ejaculated sperms, is influenced by lifestyle habits or environmental factors and by inherited factors. However, genetic factors contributing to individual differences in sperm motility remain unclear. To identify genetic factors that influence human sperm motility, we performed a genome-wide association study (GWAS) of sperm motility. METHODS: A two-stage GWAS was conducted using 811 Japanese men in a discovery stage, followed by a replication study using an additional 779 Japanese men. RESULTS: In the two-staged GWAS, a single nucleotide polymorphism rs3791686 in the intron of gene for erb-b2 receptor tyrosine kinase 4 (ERBB4) on chromosome 2q34 was identified as a novel locus for sperm motility, as evident from the discovery and replication results using meta-analysis (beta= 4.01, combined P=5.40*10-9). CONCLUSIONS: Together with the previous evidence that Sertoli cell-specific Erbb4-knockout mice display an impaired ability to produce motile sperm, this finding provides the first genetic evidence for further investigation of the genome-wide significant association at the ERBB4 locus in larger studies across diverse human populations. PMID- 29453197 TI - Paediatric hospital admission processes and outcomes: a qualitative study of parents' experiences and priorities. AB - BACKGROUND: Hospital admission, like hospital discharge, represents a transition of care associated with changes in setting, healthcare providers and clinical management. While considerable efforts have focused on improving the quality and safety of hospital-to-home transitions, there has been little focus on transitions into hospital. OBJECTIVES: Among children hospitalised with ambulatory care sensitive conditions, we aimed to characterise families' experiences as they transitioned from outpatient to inpatient care, identify hospital admission processes and outcomes most important to families and determine how parental perspectives differed between children admitted directly and through emergency departments (ED). METHODS: We conducted semistructured interviews with parents of hospitalised children at four structurally diverse hospitals. We inquired about preadmission healthcare encounters, how hospital admission decisions were made and parents' preferences regarding hospital admission processes and outcomes. Interviews were transcribed verbatim and analysed using a general inductive approach. RESULTS: We conducted 48 interviews. Participants were predominantly mothers (74%); 45% had children with chronic illnesses and 52% were admitted directly. Children had a median of two (IQR 1-3) healthcare encounters in the week preceding hospital admission, with 44% seeking care in multiple settings. Patterns of healthcare utilisation were influenced by (1) disease acuity and healthcare access; (2) past experiences; and (3) varied perspectives about primary care and ED roles as hospital gatekeepers. Participants' hospital admission priorities included: (1) effective clinical care; (2) efficient admission processes; (3) safety and security; (4) timeliness; and (5) patient and family-centred processes of care. CONCLUSIONS: Families received preadmission care in several settings and described varying degrees of care coordination during their admission processes. This research can guide improvements in hospitals' admission systems, necessary to achieve health system integration and continuity of care. PMID- 29453198 TI - Targeting KCa1.1 Channels with a Scorpion Venom Peptide for the Therapy of Rat Models of Rheumatoid Arthritis. AB - Fibroblast-like synoviocytes (FLSs) are a key cell type involved in rheumatoid arthritis (RA) progression. We previously identified the KCa1.1 potassium channel (Maxi-K, BK, Slo 1, KCNMA1) as a regulator of FLSs and found that KCa1.1 inhibition reduces disease severity in RA animal models. However, systemic KCa1.1 block causes multiple side effects. In this study, we aimed to determine whether the KCa1.1 beta1-3-specific venom peptide blocker iberiotoxin (IbTX) reduces disease severity in animal models of RA without inducing major side effects. We used immunohistochemistry to identify IbTX-sensitive KCa1.1 subunits in joints of rats with a model of RA. Patch-clamp and functional assays were used to determine whether IbTX can regulate FLSs through targeting KCa1.1. We then tested the efficacy of IbTX in ameliorating disease in two rat models of RA. Finally, we determined whether IbTX causes side effects including incontinence or tremors in rats, compared with those treated with the small-molecule KCa1.1 blocker paxilline. IbTX-sensitive subunits of KCa1.1 were expressed by FLSs in joints of rats with experimental arthritis. IbTX inhibited KCa1.1 channels expressed by FLSs from patients with RA and by FLSs from rat models of RA and reduced FLS invasiveness. IbTX significantly reduced disease severity in two rat models of RA. Unlike paxilline, IbTX did not induce tremors or incontinence in rats. Overall, IbTX inhibited KCa1.1 channels on FLSs and treated rat models of RA without inducing side effects associated with nonspecific KCa1.1 blockade and could become the basis for the development of a new treatment of RA. PMID- 29453199 TI - Simultaneous Assessment of Clearance, Metabolism, Induction, and Drug-Drug Interaction Potential Using a Long-Term In Vitro Liver Model for a Novel Hepatitis B Virus Inhibitor. AB - Long-term in vitro liver models are now widely explored for human hepatic metabolic clearance prediction, enzyme phenotyping, cross-species metabolism, comparison of low clearance drugs, and induction studies. Here, we present studies using a long-term liver model, which show how metabolism and active transport, drug-drug interactions, and enzyme induction in healthy and diseased states, such as hepatitis B virus (HBV) infection, may be assessed in a single test system to enable effective data integration for physiologically based pharmacokinetic (PBPK) modeling. The approach is exemplified in the case of (3S) 4-[[(4R)-4-(2-Chloro-4-fluorophenyl)-5-methoxycarbonyl-2-thiazol-2-yl-1,4 dihydropyrimidin-6-yl]methyl]morpholine-3-carboxylic acid RO6889678, a novel inhibitor of HBV with a complex absorption, distribution, metabolism, and excretion (ADME) profile. RO6889678 showed an intracellular enrichment of 78-fold in hepatocytes, with an apparent intrinsic clearance of 5.2 ul/min per mg protein and uptake and biliary clearances of 2.6 and 1.6 ul/min per mg protein, respectively. When apparent intrinsic clearance was incorporated into a PBPK model, the simulated oral human profiles were in good agreement with observed data at low doses but were underestimated at high doses due to unexpected overproportional increases in exposure with dose. In addition, the induction potential of RO6889678 on cytochrome P450 (P450) enzymes and transporters at steady state was assessed and cotreatment with ritonavir revealed a complex drug drug interaction with concurrent P450 inhibition and moderate UDP glucuronosyltransferase induction. Furthermore, we report on the first evaluation of in vitro pharmacokinetics studies using HBV-infected HepatoPac cocultures. Thus, long-term liver models have great potential as translational research tools exploring pharmacokinetics of novel drugs in vitro in health and disease. PMID- 29453200 TI - Risk of Cardiovascular Disease and Death in Individuals With Prediabetes Defined by Different Criteria: The Whitehall II Study. AB - OBJECTIVE: We compared the risk of cardiovascular disease (CVD) and all-cause mortality in subgroups of prediabetes defined by fasting plasma glucose (FPG), 2 h plasma glucose (2hPG), or HbA1c. RESEARCH DESIGN AND METHODS: In the Whitehall II cohort, 5,427 participants aged 50-79 years and without diabetes were followed for a median of 11.5 years. A total of 628 (11.6%) had prediabetes by the World Health Organization (WHO)/International Expert Committee (IEC) criteria (FPG 6.1 6.9 mmol/L and/or HbA1c 6.0-6.4%), and 1,996 (36.8%) by the American Diabetes Association (ADA) criteria (FPG 5.6-6.9 mmol/L and/or HbA1c 5.7-6.4%). In a subset of 4,730 individuals with additional measures of 2hPG, 663 (14.0%) had prediabetes by 2hPG. Incidence rates of a major event (nonfatal/fatal CVD or all cause mortality) were compared for different definitions of prediabetes, with adjustment for relevant confounders. RESULTS: Compared with that for normoglycemia, incidence rate in the context of prediabetes was 54% higher with the WHO/IEC definition and 37% higher with the ADA definition (P < 0.001) but declining to 17% and 12% after confounder adjustment (P >= 0.111). Prediabetes by HbA1c was associated with a doubling in incidence rate for both the IEC and ADA criteria. However, upon adjustment, excess risk was reduced to 13% and 17% (P >= 0.055), respectively. Prediabetes by FPG or 2hPG was not associated with an excess risk in the adjusted analysis. CONCLUSIONS: Prediabetes defined by HbA1c was associated with a worse prognosis than prediabetes defined by FPG or 2hPG. However, the excess risk among individuals with prediabetes is mainly explained by the clustering of other cardiometabolic risk factors associated with hyperglycemia. PMID- 29453201 TI - Hypercalcemia associated with cosmetic injections: a systematic review. AB - INTRODUCTION: Cosmetic injections with silicone and polymethylmethacrylate are not FDA approved for augmentation of body parts such as breast, buttock or legs, but they have been widely used for decades. Cosmetic injections can cause foreign body granulomas and occasionally severe and life-threatening hypercalcemia. We aimed to systematically analyze the published literature on cosmetic injection associated hypercalcemia. METHODS: We searched relevant articles on hypercalcemia associated with various cosmetic injections and extracted relevant data on demographics, cosmetic injections used, severity of hypercalcemia, management and outcomes. RESULTS: We identified 23 eligible patients from 20 articles. Mean age was 49.83 +/- 14.70 years with a female preponderance (78.26% including transgender females). Silicone was most commonly used, followed by polymethylmethacrylate and paraffin oil (43.48, 30.43, and 8.70% respectively). The buttock was the most common site followed by the breast (69.57% and 39.13% respectively). Hypercalcemia developed at mean duration of 7.96 +/- 7.19 years from the initial procedure. Mean ionized calcium at presentation was 2.19 +/- 0.61 mmol/L and mean corrected calcium at presentation was 3.43 +/- 0.31 mmol/L. 1,25-Dihydroxyvitamin D (1,25(OH)2D or calcitriol) was elevated while 25 hydroxyvitamin D (25(OH)D) and PTH were low in majority of cases. Hypercalcemia was managed conservatively with hydration, corticosteroids and bisphosphonates in majority of cases. Surgery was attempted in 2 cases but was unsuccessful. Renal failure was the most common complication (82.35% cases) and 2 patients died. CONCLUSION: Hypercalcemia from cosmetic injections can be severe and life threatening and can present years after the initial procedure. Cosmetic injection associated granuloma should be considered a cause of hypercalcemia, especially in middle-aged females presenting with non-PTH-mediated, non-malignant hypercalcemia, which is often associated with elevated calcitriol; however, it should be noted that calcitriol level may be normal as well. PMID- 29453202 TI - MANAGEMENT OF ENDOCRINE DISEASE Hyperandrogenic states in women: pitfalls in laboratory diagnosis. AB - Measuring total testosterone level is the first-line approach in assessing androgen excess in women. The main pitfalls in measuring testosterone relate to its low concentration and to the structural similarity between circulating androgens and testosterone, requiring accurate techniques with high specificity and sensitivity. These goals can be achieved by immunoassay using a specific anti testosterone monoclonal antibody, ideally after an extraction step. Liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) will be commonly used for measuring testosterone, providing optimal accuracy with a low limit of detection. Yet, the pitfalls of these two techniques are well identified and must be recognized and systematically addressed. In general, laboratories using direct testosterone immunoassay and mass spectrometry need to operate within a quality framework and be actively engaged in external quality control processes and standardization, so as to ensure appropriate interpretation irrespective of the particular laboratory. Circulating testosterone is strongly bound to sex-hormone binding globulin (SHBG), and SHBG levels are typically low in overweight hyperandrogenic patients. Thus, low SHBG may decrease circulating testosterone to normal values, which will mask androgen excess status. One way to avoid this pitfall, awaiting direct free testosterone assays that are yet to be developed, is to measure SHBG and calculate free testosterone. A few other pitfalls will be discussed in this review, including those of adrenal androgen exploration, with the aim of helping clinicians to better handle laboratory investigation of androgen excess disorders in women. PMID- 29453204 TI - Circulating miRNA Profiles Associated With Hyperglycemia in Patients With Type 1 Diabetes. AB - We investigated plasma microRNA (miRNA) profiles associated with variation of hyperglycemia, measured as hemoglobin A1c (HbA1c), in two panels of patients with type 1 diabetes (T1D). Using the HTG Molecular Diagnostics EdgeSeq platform, 2,083 miRNAs were measured in plasma from 71 patients included in a screening panel. Quantitative real-time PCR was used to measure the candidate miRNAs in plasma from 95 patients included in an independent replication panel. We found 10 miRNAs replicated in both panels and 4 with high statistical significance. The strongest positive correlations with HbA1c were found with miR-125b-5p (rs = 0.40, P = 6.0 * 10-5) and miR-365a-3p (rs = 0.35, P = 5.9 * 10-4). The strongest negative correlations were found with miR-5190 (rs = -0.30, P = 0.003) and miR 770-5p (rs = -0.27, P = 0.008). Pathway analysis revealed that 50 Kyoto Encyclopedia of Genes and Genomes pathways were significantly enriched by genes targeted by these four miRNAs. The axon guidance signaling pathway was enriched (P < 1 * 10-7) by genes targeted by all four miRNAs. In addition, three other pathways (Rap1 signaling, focal adhesion, and neurotrophin signaling) were also significantly enriched but with genes targeted by only by three of the identified miRNAs. In conclusion, our study identified four circulating miRNAs that were influenced by variation in hyperglycemia. Dysregulation of these miRNAs, which are associated with hyperglycemia in patients with T1D, may contribute to the development of diabetes complications. However, there are multitudes of possible mechanisms/pathways through which dysregulation of these miRNAs may impact risk of diabetes complications. PMID- 29453206 TI - Elevation of Hippocampal Neurogenesis Induces a Temporally Graded Pattern of Forgetting of Contextual Fear Memories. AB - Throughout life neurons are continuously generated in the subgranular zone of the hippocampus. The subsequent integration of newly generated neurons alters patterns of dentate gyrus input and output connectivity, potentially rendering memories already stored in those circuits harder to access. Consistent with this prediction, we previously showed that increasing hippocampal neurogenesis after training induces forgetting of hippocampus-dependent memories, including contextual fear memory. However, the brain regions supporting contextual fear memories change with time, and this time-dependent memory reorganization might regulate the sensitivity of contextual fear memories to fluctuations in hippocampal neurogenesis. By virally expressing the inhibitory designer receptor exclusively activated by designer drugs, hM4Di, we first confirmed that chemogenetic inhibition of dorsal hippocampal neurons impairs retrieval of recent (day-old) but not remote (month-old) contextual fear memories in male mice. We then contrasted the effects of increasing hippocampal neurogenesis at recent versus remote time points after contextual fear conditioning in male and female mice. Increasing hippocampal neurogenesis immediately following training reduced conditioned freezing when mice were replaced in the context 1 month later. In contrast, when hippocampal neurogenesis was increased time points remote to training, conditioned freezing levels were unaltered when mice were subsequently tested. These temporally graded forgetting effects were observed using both environmental and genetic interventions to increase hippocampal neurogenesis. Our experiments identify memory age as a boundary condition for neurogenesis-mediated forgetting and suggest that, as contextual fear memories mature, they become less sensitive to changes in hippocampal neurogenesis levels because they no longer depend on the hippocampus for their expression.SIGNIFICANCE STATEMENT New neurons are generated in the hippocampus throughout life. As they integrate into the hippocampus, they remodel neural circuitry, potentially making information stored in those circuits harder to access. Consistent with this, increasing hippocampal neurogenesis after learning induces forgetting of the learnt information. The current study in mice asks whether these forgetting effects depend on the age of the memory. We found that post-training increases in hippocampal neurogenesis only impacted recently acquired, and not remotely acquired, hippocampal memories. These experiments identify memory age as a boundary condition for neurogenesis mediated forgetting, and suggest remote memories are less sensitive to changes in hippocampal neurogenesis levels because they no longer depend critically on the hippocampus for their expression. PMID- 29453205 TI - Codeficiency of Lysosomal Mucolipins 3 and 1 in Cochlear Hair Cells Diminishes Outer Hair Cell Longevity and Accelerates Age-Related Hearing Loss. AB - Acquired hearing loss is the predominant neurodegenerative condition associated with aging in humans. Although mutations on several genes are known to cause congenital deafness in newborns, few genes have been implicated in age-related hearing loss (ARHL), perhaps because its cause is likely polygenic. Here, we generated mice lacking lysosomal calcium channel mucolipins 3 and 1 and discovered that both male and female mice suffered a polygenic form of hearing loss. Whereas mucolipin 1 is ubiquitously expressed in all cells, mucolipin 3 is expressed in a small subset of cochlear cells, hair cells (HCs) and marginal cells of the stria vascularis, and very few other cell types. Mice lacking both mucolipins 3 and 1, but not either one alone, experienced hearing loss as early as at 1 month of age. The severity of hearing impairment progressed from high to low frequencies and increased with age. Early onset of ARHL in these mice was accompanied by outer HC (OHC) loss. Adult mice conditionally lacking mucolipins in HCs exhibited comparable auditory phenotypes, thereby revealing that the reason for OHC loss is mucolipin codeficiency in the HCs and not in the stria vascularis. Furthermore, we observed that OHCs lacking mucolipins contained abnormally enlarged lysosomes aggregated at the apical region of the cell, whereas other organelles appeared normal. We also demonstrated that these aberrant lysosomes in OHCs lost their membrane integrity through lysosomal membrane permeabilization, a known cause of cellular toxicity that explains why and how OHCs die, leading to premature ARHL.SIGNIFICANCE STATEMENT Presbycusis, or age-related hearing loss (ARHL), is a common characteristic of aging in mammals. Although many genes have been identified to cause deafness from birth in both humans and mice, only a few are known to associate with progressive ARHL, the most prevalent form of deafness. We have found that mice lacking two lysosomal channels, mucolipins 3 and 1, suffer accelerated ARHL due to auditory outer hair cell degeneration, the most common cause of hearing loss and neurodegenerative condition in humans. Lysosomes lacking mucolipins undergo organelle membrane permeabilization and promote cytotoxicity with age, revealing a novel mechanism of outer hair cell degeneration and ARHL. These results underscore the importance of lysosomes in hair cell survival and the maintenance of hearing. PMID- 29453207 TI - Hippocampal Ripple Oscillations and Inhibition-First Network Models: Frequency Dynamics and Response to GABA Modulators. AB - Hippocampal ripples are involved in memory consolidation, but the mechanisms underlying their generation remain unclear. Models relying on interneuron networks in the CA1 region disagree on the predominant source of excitation to interneurons: either "direct," via the Schaffer collaterals that provide feedforward input from CA3 to CA1, or "indirect," via the local pyramidal cells in CA1, which are embedded in a recurrent excitatory-inhibitory network. Here, we used physiologically constrained computational models of basket-cell networks to investigate how they respond to different conditions of transient, noisy excitation. We found that direct excitation of interneurons could evoke ripples (140-220 Hz) that exhibited intraripple frequency accommodation and were frequency-insensitive to GABA modulators, as previously shown in in vitro experiments. In addition, the indirect excitation of the basket-cell network enabled the expression of intraripple frequency accommodation in the fast-gamma range (90-140 Hz), as in vivo In our model, intraripple frequency accommodation results from a hysteresis phenomenon in which the frequency responds differentially to the rising and descending phases of the transient excitation. Such a phenomenon predicts a maximum oscillation frequency occurring several milliseconds before the peak of excitation. We confirmed this prediction for ripples in brain slices from male mice. These results suggest that ripple and fast-gamma episodes are produced by the same interneuron network that is recruited via different excitatory input pathways, which could be supported by the previously reported intralaminar connectivity bias between basket cells and functionally distinct subpopulations of pyramidal cells in CA1. Together, our findings unify competing inhibition-first models of rhythm generation in the hippocampus.SIGNIFICANCE STATEMENT The hippocampus is a part of the brain of humans and other mammals that is critical for the acquisition and consolidation of memories. During deep sleep and resting periods, the hippocampus generates high-frequency (~200 Hz) oscillations called ripples, which are important for memory consolidation. The mechanisms underlying ripple generation are not well understood. A prominent hypothesis holds that the ripples are generated by local recurrent networks of inhibitory neurons. Using computational models and experiments in brain slices from rodents, we show that the dynamics of interneuron networks clarify several previously unexplained characteristics of ripple oscillations, which advances our understanding of hippocampus-dependent memory consolidation. PMID- 29453208 TI - Parent-reported prevalence and persistence of 19 common child health conditions. AB - OBJECTIVE: To estimate prevalence and persistence of 19 common paediatric conditions from infancy to 14-15 years. DESIGN: Population-based prospective cohort study. SETTING: Australia. PARTICIPANTS: Parallel cohorts assessed biennially from 2004 to 2014 from ages 0-1 and 4-5 years to 10-11 and 14-15 years, respectively, in the Longitudinal Study of Australian Children. MAIN OUTCOME MEASURES: 19 health conditions: 17 parent-reported, 2 (overweight/obesity, obesity) directly assessed. Two general measures: health status, special health care needs. ANALYSIS: (1) prevalence estimated in 2-year age-bands and (2) persistence rates calculated at each subsequent time point for each condition among affected children. RESULTS: 10 090 children participated in Wave 1 and 6717 in all waves. From age 2, more than 60% of children were experiencing at least one health condition at any age. Distinct prevalence patterns by age-bands comprised eight conditions that steadily rose (overweight/obesity, obesity, injury, anxiety/depression, frequent headaches, abdominal pain, autism spectrum disorder, attention-deficit hyperactivity disorder). Six conditions fell with age (eczema, sleep problems, day-wetting, soiling, constipation, recurrent tonsillitis), three remained stable (asthma, diabetes, epilepsy) and two peaked in mid-childhood (dental decay, recurrent ear infections). Conditions were more likely to persist if present for 2 years; persistence was especially high for obesity beyond 6-7 (91.3%-95.1% persisting at 14-15). CONCLUSIONS: Beyond infancy, most Australian children are experiencing at least one ongoing health condition at any given time. This study's age-specific estimates of prevalence and persistence should assist families and clinicians to plan care. Conditions showing little resolution (obesity, asthma, attention deficit hyperactivity disorder) require long-term planning and management. PMID- 29453209 TI - Recurrent epistaxis leading to diagnosis of primary sinonasal melanoma. AB - A 48-year-old man presented to urgent care with recurrent epistaxis over 6 months. Initially, nosebleeds were controlled with packing or cautery. Ultimately, he was referred to ear, nose and throat department and underwent nasal endoscopy which revealed polypoid tissue. A biopsy of the polyp showed non specific inflammation with no evidence of malignancy. Follow-up maxillofacial CT revealed a large mass lesion in the right maxillary sinus, right nasal fossa, much of the ethmoids and right sphenoid, with destruction of adjacent bony structures. MRI revealed a mass in the right nasal cavity with extension into the ethmoid and anterior sphenoid sinus, anterior cranial fossa and medial orbits. Staging CT discovered metastatic disease in the adrenal glands and lymphadenopathy in the neck. The patient underwent endoscopic sinus surgery with debulking and tissue diagnosis of malignant melanoma. He completed radiation therapy to sinus and was subsequently enrolled in a clinical trial. Most recent imaging revealed complete metabolic response on positron emission tomography. PMID- 29453210 TI - Polymicrobial bacterial pericarditis and cardiac tamponade caused by pericardial penetration of an adjustable gastric band. AB - We describe a case of polymicrobial bacterial pericarditis with Klebsiella pneumoniae and Proteus mirabilis, caused by pericardial penetration of the tip of the catheter of a laparoscopic adjustable gastric band (LAGB). The patient developed a cardiac tamponade, and subsequently emergency pericardiocentesis was performed. Analysis of earlier CT scans showed that the tip of the catheter had migrated through the liver and through the diaphragm into the pericardium, and was in contact with the myocardium. After stabilisation he was operated to remove the LAGB. In this case report, we describe the chain of events that led to the polymicrobial pericarditis-a complication of LAGB placement that to our knowledge has thus far never been reported. We furthermore present a detailed literature review of all published cases of polymicrobial pericarditis and its causes. PMID- 29453211 TI - Fistulation between a colonic J-Pouch and the upper vagina in an irradiated pelvis: a rare complication following low anterior resection with colonic J-pouch anal anastomosis for rectal cancer. AB - Formation of a colonic J-pouch with anastomosis to the rectal stump is an accepted form of reconstruction after low anterior resection (LAR) for rectal carcinoma. It is thought this can help prevent the onset of LAR syndrome as well as improve the quality of life in the first two years following surgery. Rectovaginal fistulation is a recognised complication of this form of surgery usually occurring because of technical failure leading to inclusion of the vaginal wall into the stapled anastomosis. We present an as of yet unreported case of fistulation between the upper horizontal staple line of a colonic J-pouch the tip of the 'J'-which was formed extracorporeally with the posterior vaginal fornix. We postulate that pelvic irradiation was partly a causative factor alongside subsequent mechanical irritation. Ultimately, surgical intervention was required, following which the patient made a full recovery. Interposition of omentum may prevent this problem.

AB - A left atrial appendage occluder device (Watchman) and leadless pacemaker (Micra) was implanted from a single right femoral vein access in a 73-year-old female patient with persistent atrial fibrillation and symptomatic tachy-brady syndrome and unable to take oral anticoagulants. Standard methods of implantation were followed for both procedures. The Watchman device was implanted first followed by dilatation of the same venous access site in order to implant Micra transcatheter pacing system. The patient tolerated the procedures well and there were no complications. At the end of 1 month, both the devices were found to be working well.

AB - A healthy patient presented with painful skin lesions on the anterior surface of her legs. Erythema nodosum was diagnosed but all the usual causes were ruled out. The finding of bilateral enlarged axillary lymph nodes with necrosis and granulomas led to the diagnosis of Bartonella infection, an unusual cause of erythema nodosum. Imaging also revealed splenomegaly and small para-aortic lymph nodes. Up to one quarter of the patients with cat-scratch disease present atypically, a considerably higher prevalence than previously reported. A comprehensive review of the literature (PubMed, since inception, all languages) revealed a remarkable array of unusual presentations which are summarised and briefly discussed. PMID- 29453214 TI - Renal nutcracker syndrome in a young lady: unusual findings and endovascular management. AB - Nutcracker syndrome (NCS) is caused by compression of left renal vein (LRV), usually between the aorta and the superior mesenteric artery (SMA). This can lead to obstruction of flow into the inferior vena cava and secondary left renal venous hypertension. Despite potential serious consequences, diagnosing NCS is often challenging, circuitous and commonly delayed. We report an extremely unique case of NCS. A 34-year-old woman presented with left flank pain and discomfort. On investigation, it was found that high pressure in the LRV, due to compression by the SMA, had led to a large venous aneurysm that had caused pelviureteric junction obstruction and hydronephrosis. Management was with stenting of the LRV and coil embolisation of the venous aneurysm with excellent clinical outcome. PMID- 29453215 TI - Syncope and cardiogenic shock in an 80-year-old woman.

PMID- 29453217 TI - Time spent in inactive disease before MTX withdrawal is relevant with regard to the flare risk in patients with JIA. AB - OBJECTIVES: To determine the reasons of methotrexate (MTX) discontinuation, frequency of adverse events (AE) and whether the time in inactive disease before MTX withdrawal disease is associated with the risk of disease flare. METHODS: Patients with juvenile idiopathic arthritis (JIA) beginning treatment with MTX were prospectively observed in the national JIA biologic register Biologika in der Kinderrheumatologie/Biologics in Paediatric Rheumatology and its follow-up register Juvenile arthritis Methotrexate/Biologics long-term Observation. Inactive disease was defined by a clinical Juvenile Arthritis Disease Activity Score <=1, flare after MTX discontinuation by reoccurrence of at least moderate disease activity or restart of treatment with a disease-modifying antirheumatic drug . RESULTS: MTX treatment was initiated in 1514 patients after a mean disease duration of 2.1 years (SD=2.8). 40% of the patients experienced oligoarticular onset of JIA. MTX was discontinued in 982 (64.9%) patients. Ineffectiveness (36.9%) and achieving inactive disease (32.1%) were the most common reasons. Among the latter (n=316), 184 (58.2%) patients experienced a flare on follow-up. The likelihood of a flare was a function of time in inactive disease prior to MTX discontinuation (HR 0.95; 95% CI 0.92 to 0.97). Patients with inactive disease for longer than 12 months had a significantly lower flare rate (58 of 119, 48.7%; HR 0.48; 95% CI 0.34 to 0.69). The most frequently reported AE was MTX intolerance, including nausea, aversion and vomiting, accounting for 441 events (13.0 events/100 exposure years) in 307 (20.3%) patients. CONCLUSIONS: Patients who spent at least 12 months in inactive disease before MTX discontinuation had a significantly lower flare rate.

PMID- 29453220 TI - Identification of novel fusion transcripts in multiple myeloma. AB - AIMS: Multiple myeloma (MM) is a heterogeneous disease characterised by genetically complex abnormalities. The classical mutational spectrum includes recurrent chromosomal aberrations and gene-level mutations. Recurrent translocations involving the IGH gene such as t(11;14), t(4;14) and t(14;16) are well known. However, the presence of complex genetic abnormalities raises the possibility that fusions other than the recurrent IGH translocations exist. We therefore employed a targeted RNA-sequencing panel to identify novel putative fusions in a local cohort of MM. METHODS: Targeted RNA-sequencing was performed on 21 patient samples using the Illumina TruSight RNA Pan-Cancer Panel (comprising 1385 genes). Fusion calls were generated from the Illumina RNA Sequencing Alignment software (V.1.0.0). These samples had conventional cytogenetic and fluorescence in situ hybridisation data for the common recurrent chromosomal abnormalities (t(11;14), t(4;14), t(14;16) and 17p13 deletion). The MMRF CoMMpass dataset was analysed using the TopHat-fusion pipeline. RESULTS: A total of 10 novel fusions were identified by the TruSight RNA Pan-Cancer Panel. Two of these fusions, HGF/CACNA2D1 and SMC3/MXI1, were validated by reverse transcription PCR and Sanger sequencing as they involve genes that may have biological relevance in MM genesis. Four of these (MAP2K4/MAP2K4P1) are likely to be spurious secondary to misalignment of reads to a pseudogene. One record of the HGF/CACNA2D1 fusion was identified from the MMRF CoMMpass dataset. CONCLUSIONS: The identification of novel fusions offers insights into the biology of MM and might have clinical relevance. Further functional studies are required to determine the biological and clinical relevance of these novel fusions.

AB - BACKGROUND: To describe the surgical technique and refractive outcomes following clear lens extraction (CLE) in the Effectiveness, in Angle-closure Glaucoma, of Lens Extraction trial. METHODS: Review of prospectively collected data from a multicentre, randomised controlled trial comparing CLE and laser peripheral iridotomy. Eligible participants were >=50 years old and newly diagnosed with (1) primary angle closure (PAC) with intraocular pressure above 30 mm Hg or (2) PAC glaucoma. We report the postoperative corrected distance visual acuity (CDVA) and refractive outcomes at 12 and 36 months postoperatively for those who underwent CLE. RESULTS: Of the 419 participants, 208 were randomised to CLE. Mean baseline CDVA was 77.9 (SD 12.4) letters and did not change significantly at 36 months when mean CDVA was 79.9 (SD 10.9) letters. Mean preoperative spherical equivalents were +1.7 (SD 2.3) and +0.08 (SD 0.95) diopters (D) at 36 months. Fifty-nine per cent and 85% eyes were within +/-0.5D and +/-1.0D of predicted refraction, respectively, at 36 months. CONCLUSIONS: Mean CDVA in patients undergoing CLE for angle-closure glaucoma appeared stable over the 3-year study period. Refractive error was significantly reduced with surgery but refractive predictability was suboptimal. TRIAL REGISTRATION NUMBER: PMID- 29453221 TI - H3K9 demethylase KDM4E is an epigenetic regulator for bovine embryonic development and a defective factor for nuclear reprogramming. AB - Aberrant epigenetic reprogramming often results in developmental defects in somatic cell nuclear transfer (SCNT) embryos during embryonic genome activation (EGA). Bovine eight-cell SCNT embryos exhibit global hypermethylation of histone H3 lysine 9 tri- and di-methylation (H3K9me3/2), but the intrinsic reason for this remains elusive. Here, we provide evidence that two H3K9 demethylase genes, lysine-specific demethylase 4D (KDM4D) and 4E (KDM4E), are related to active H3K9me3/2 demethylation in in vitro fertilized (IVF) embryos and are deficiently expressed in cloned embryos at the time of EGA. Moreover, KDM4E plays a more crucial role in IVF and SCNT embryonic development, and overexpression of KDM4E can restore the global transcriptome, improve blastocyst formation and increase the cloning efficiency of SCNT embryos. Our results thereby indicate that KDM4E can function as a crucial epigenetic regulator of EGA and as an internal defective factor responsible for persistent H3K9me3/2 barriers to SCNT-mediated reprogramming. Furthermore, we show that interactions between RNA and KDM4E are essential for H3K9 demethylation during EGA. These observations advance the understanding of incomplete nuclear reprogramming and are of great importance for transgenic cattle procreation.

AB - The biological, structural and functional configuration of Bruch's membrane (BM) is significantly relevant to age-related macular degeneration (AMD) and other chorioretinal diseases, and AMD is one of the leading causes of blindness in the elderly worldwide. The configuration may worsen along with the ageing of retinal pigment epithelium and BM that finally leads to AMD. Thus, the scaffold-based tissue-engineered retina provides an innovative alternative for retinal tissue repair. The cell and material requirements for retinal repair are discussed including cell sheet engineering, decellularised membrane and tissue-engineered membranes. Further, the challenges and potential in realising a whole tissue model construct for retinal regeneration are highlighted herein. This review article provides a framework for future development of tissue-engineered retina as a preclinical model and possible treatments for AMD. PMID- 29453224 TI - Simple limbal epithelial transplantation (SLET) in failed cultivated limbal epithelial transplantation (CLET) for unilateral chronic ocular burns. AB - AIMS: Cultivated limbal epithelial transplantation (CLET) fails in around 20%-30% of cases. This study aimed to report the clinical outcomes of autologous simple limbal epithelial transplantation (SLET) in eyes with recurrent unilateral limbal stem cell deficiency (LSCD) due to failure of CLET. METHODS: This was a prospective case series which included 30 eyes of 30 patients who underwent SLET between 2010 and 2016 after failure of one (n=24) or two (n=6) previous CLET procedures for chronic unilateral ocular burns. The primary outcome measure was success of SLET defined on the basis of relative improvement in five objective criteria: best corrected visual acuity (BCVA), and grades of symblepharon, corneal conjunctivalisation, vascularisation and opacification. RESULTS: At a mean follow-up of 2.3 years, 24 (80%) of the 30 eyes maintained a successful outcome. Kaplan-Meier analysis showed a 5-year survival probability of 77%+/-8%. At 1 year postoperatively statistically significant improvement was noted in BCVA (logarithm of the minimum angle of resolution of 3 to 1) and in the median grades of corneal conjunctivalisation (2 to 0), vascularisation (2 to 0) and opacification (2 to 1) (P<=0.0026). In 62.5% of successful cases, BCVA improved to 20/200 or better. The success rate of SLET in failed CLET was better than that of repeat CLET (53.5%, P=0.011). None of the donor eyes developed any complications. CONCLUSION: SLET is an effective alternative to CLET in eyes with recurrence of LSCD after previously failed CLET procedures. Since SLET is single staged and less expensive, it is probably preferable to repeating CLET. PMID- 29453225 TI - Prevalence of age-related macular degeneration associated genetic risk factors and 4-year progression data in the Irish population. AB - BACKGROUND/AIMS: Age-related macular degeneration (AMD) is estimated to affect 196 million people >50 years old globally. Prevalence of AMD-associated genetic risk factors and rate of disease progression are unknown in Ireland. METHODS: Prevalence of AMD-associated genetic risk variants, complement factor H (CFH) rs1061170, age-related maculopathy susceptibility 2 (ARMS2) rs10490924, component 3 (C3) rs2230199, complement factor B (CFB) rs641153 and superkiller viralicidic activity 2-like (SKIV2L) rs429608 and 4-year progression data in a population representative cohort (The Irish Longitudinal study on Ageing (TILDA)) were assessed. 4473 participants >=50 years were assessed. 4173 had no disease n=1843; 44% male and n=2330; 56% female, mean age 60+/-9.0, 300 had AMD n=136; 45% male and n=164; 55% female, mean age 64+/-9.0. A 4-year follow-up was undertaken with 66% of AMD cases attending. Progression and regression from early to late AMD were measured. Genetic association as indicators of disease and as predictors of progression were assessed by multinomial logistic regression. RESULTS: Older age and the presence of CFH and ARMS2 risk alleles are two main risk factors associated with the prevalence of AMD in the TILDA cohort. 23% progressed to a higher grade of AMD. Carriers of CFH risk allele showed a strong association for disease progression. Heterozygosity for ARMS2 risk allele predicted progression to late AMD. 75% of those who progressed from early to late disease had soft drusen and hyperpigmentation at baseline. CONCLUSIONS: The prevalence of risk associated genes and 4-year progression rates of AMD in this Ireland cohort are comparable with other Caucasian populations. CFH Y402H is associated with disease progression, with soft drusen and hyperpigmentation as high-risk features. PMID- 29453227 TI - LLM-Domain B-GATA Transcription Factors Play Multifaceted Roles in Controlling Greening in Arabidopsis. AB - Chlorophyll accumulation and chloroplast development are regulated at multiple levels during plant development. The paralogous LLM-domain B-GATA transcription factors GNC and GNL contribute to chlorophyll biosynthesis and chloroplast formation in light-grown Arabidopsis thaliana seedlings. Whereas there is already ample knowledge about the transcriptional regulation of GNC and GNL, the identity of their downstream targets is largely unclear. Here, we identified genes controlling greening directly downstream of the GATAs by integrating data from RNA-sequencing and microarray data sets. We found that genes encoding subunits of the Mg-chelatase complex and 3,8-divinyl protochlorophyllide a 8-vinyl reductase (DVR) likely function directly downstream of the GATAs and that DVR expression is limiting in the pale-green gnc gnl mutants. The GATAs also regulate the nucleus encoded SIGMA (SIG) factor genes, which control transcription in the chloroplast and suppress the greening defects of sig mutants. Furthermore, GNC and GNL act, at the gene expression level, in an additive manner with the GOLDEN2-LIKE1 (GLK1) and GLK2 transcription factor genes, which are also important for proper chlorophyll accumulation. We thus reveal that chlorophyll biosynthesis genes are directly controlled by LLM-domain B-GATAs and demonstrate that these transcription factors play an indirect role in the control of greening through regulating SIGMA factor genes.

AB - Xenotransplantation of patient-derived samples in mouse models has been instrumental in depicting the role of hematopoietic stem and progenitor cells in the establishment as well as progression of hematological malignancies. The foundations for this field of research have been based on the development of immunodeficient mouse models, which provide normal and malignant human hematopoietic cells with a supportive microenvironment. Immunosuppressed and genetically modified mice expressing human growth factors were key milestones in patient-derived xenograft (PDX) models, highlighting the importance of developing humanized microenvironments. The latest major improvement has been the use of human bone marrow (BM) niche-forming cells to generate human-mouse chimeric BM tissues in PDXs, which can shed light on the interactions between human stroma and hematopoietic cells. Here, we summarize the methods used for human hematopoietic cell xenotransplantation and their milestones and review the latest approaches in generating humanized BM tissues in mice to study human normal and malignant hematopoiesis. PMID- 29453230 TI - Role of biomarkers in predicting the occurrence of thyroid neoplasms in radiation exposed children. AB - With increasing numbers of childhood cancer survivors who were treated with radiation, there is a need to evaluate potential biomarkers that could signal an increased risk of developing thyroid cancer. We aimed to examine the relationships between thyrotropin and thyroglobulin levels and the risk of developing thyroid nodules and cancer in a cohort of radiation-exposed children. 764 subjects who were irradiated in the neck area as children were examined and followed for up to 25 years. All subjects underwent a clinical examination, measurements of thyrotropin, thyroglobulin levels and thyroid imaging. At baseline, 216 subjects had thyroid nodules and 548 did not. Of those with nodules, 176 underwent surgery with 55 confirmed thyroid cancers. During the follow-up, 147 subjects developed thyroid nodules including 22 with thyroid cancer. Thyroglobulin levels were higher in subjects with prevalent thyroid nodules (26.1 ng/mL vs 9.37 ng/mL; P < 0.001) and in those who had an initial normal examination but later developed thyroid nodules (11.2 ng/mL vs 8.87 ng/mL; P = 0.017). There was no relationship between baseline thyrotropin levels and the prevalent presence or absence of thyroid nodules, whether a prevalent neoplasm was benign or malignant, subsequent development of thyroid nodules during follow up or whether an incident nodule was benign or malignant. In conclusion, in radiation-exposed children, higher thyroglobulin levels indicated an increased risk of developing thyroid nodules but did not differentiate between benign and malignant neoplasms. There was no association between the baseline TSH level and the risk of developing thyroid nodules or cancer. PMID- 29453228 TI - Targeted Profiling of Arabidopsis thaliana Subproteomes Illuminates Co- and Posttranslationally N-Terminal Myristoylated Proteins. AB - N-terminal myristoylation, a major eukaryotic protein lipid modification, is difficult to detect in vivo and challenging to predict in silico. We developed a proteomics strategy involving subfractionation of cellular membranes, combined with separation of hydrophobic peptides by mass spectrometry-coupled liquid chromatography to identify the Arabidopsis thaliana myristoylated proteome. This approach identified a starting pool of 8837 proteins in all analyzed cellular fractions, comprising 32% of the Arabidopsis proteome. Of these, 906 proteins contain an N-terminal Gly at position 2, a prerequisite for myristoylation, and 214 belong to the predicted myristoylome (comprising 51% of the predicted myristoylome of 421 proteins). We further show direct evidence of myristoylation in 72 proteins; 18 of these myristoylated proteins were not previously predicted. We found one myristoylation site downstream of a predicted initiation codon, indicating that posttranslational myristoylation occurs in plants. Over half of the identified proteins could be quantified and assigned to a subcellular compartment. Hierarchical clustering of protein accumulation combined with myristoylation and S-acylation data revealed that N-terminal double acylation influences redirection to the plasma membrane. In a few cases, MYR function extended beyond simple membrane association. This study identified hundreds of N acylated proteins for which lipid modifications could control protein localization and expand protein function. PMID- 29453229 TI - Crystal Structure of Plant Legumain Reveals a Unique Two-Chain State with pH Dependent Activity Regulation. AB - The vacuolar cysteine protease legumain can cleave and selectively rebuild peptide bonds, thereby vastly expanding the sequential repertoire of biomolecules. In this context, plant legumains have recently attracted particular interest. Furthermore, legumains have important roles in many physiological processes, including programmed cell death. Their efficient peptide bond ligase activity has gained tremendous interest in the design of cyclic peptides for drug design. However, the mechanistic understanding of these dual activities is incomplete and partly conflicting. Here, we present the crystal structure of a plant legumain, Arabidopsis thaliana isoform-gamma (AtLEGgamma). Employing a conserved legumain fold, the plant legumain AtLEGgamma revealed unique mechanisms of autoactivation, including a plant-specific two-chain activation state, which remains conformationally stable at neutral pH, which is a prerequisite for full ligase activity and survival in different cell compartments. The charge distribution around the alpha6-helix mediates the pH-dependent dimerization and serves as a gatekeeper for the active site, thus regulating its protease and ligase activity.

AB - Introduction: Although aspirin/NSAIDs may have potential preventive effects on several cancers, it remains unclear on gastric cancer. The purpose of this study is to compare the risk of developing gastric cancer and the histologic changes of intestinal metaplasia and neutrophil infiltration, between aspirin/NSAID users and nonusers.Methods: Using an electronic endoscopy database in two hospitals from 1996 to 2017, we analyzed the data from patients with chronic gastritis who received aspirin or NSAIDs prior to upper gastrointestinal endoscopy. One-to-one propensity score matching was performed to compare the proportion of gastric cancer, intestinal metaplasia, and neutrophil infiltration between these drug users and nonusers.Results: We analyzed 2,082 aspirin users and 2,082 nonusers as well as 898 NSAID users and 898 nonusers. Six diffuse-type and 19 intestinal-type gastric cancer, 1,243 intestinal metaplasia, and 1,503 neutrophil infiltration patients were identified. The proportion of diffuse-type gastric cancer (0.05%) was 80% lower in aspirin users compared with the nonusers (0.24%), and there was no case of diffuse-type cancer in patients who took aspirin for more than 2 years. In contrast, intestinal-type gastric cancer incidence was significantly higher in aspirin users (0.72%) compared with nonusers (0.14%). No significant differences in the incidence of gastric cancer were found between NSAID use and nonusers. NSAID use was significantly associated with decreased proportion of neutrophil infiltration compared with nonusers.Conclusion: Aspirin may have distinct effects between intestinal-type and diffuse-type gastric cancer development.

AB - Obesity, a cause of subclinical inflammation, is a risk factor for the development of postmenopausal breast cancer and is associated with poorer cancer outcomes. Docosahexaenoic acid (DHA), an omega-3 fatty acid, possesses anti inflammatory properties. We hypothesized that treatment with DHA would reduce the expression of proinflammatory genes and aromatase, the rate-limiting enzyme for estrogen biosynthesis, in benign breast tissue of overweight/obese women. A randomized, placebo-controlled, double-blind phase II study of DHA given for 12 weeks to overweight/obese women with a history of stage I-III breast cancer, DCIS/LCIS, Paget's disease, or proliferative benign breast disease was carried out. In this placebo controlled trial, the primary objective was to determine whether DHA (1,000 mg by mouth twice daily) reduced breast tissue levels of TNFalpha. Secondary objectives included evaluation of the effect of DHA on breast tissue levels of COX-2, IL1beta, aromatase, white adipose tissue inflammation, and gene expression by RNA-seq. Red blood cell fatty acid levels were measured to assess compliance. From July 2013 to November 2015, 64 participants were randomized and treated on trial (32 women per arm). Increased levels of omega-3 fatty acids in red blood cells were detected following treatment with DHA (P < 0.001) but not placebo. Treatment with DHA did not alter levels of TNFalpha (P = 0.71), or other biomarkers including the transcriptome in breast samples. Treatment with DHA was overall well-tolerated. Although compliance was confirmed, we did not observe changes in the levels of prespecified biomarkers in the breast after treatment with DHA when compared with placebo.

AB - BACKGROUND AND OBJECTIVES: Developmental-behavioral conditions are common, affecting ~15% of US children. The prevalence and complexity of these conditions are increasing despite long wait times and a limited pipeline of new providers. We surveyed a convenience sample of the developmental-behavioral pediatric (DBP) workforce to determine current practices, workforce trends, and future needs. METHODS: An electronic survey was e-mailed to 1568 members of the American Academy of Pediatrics Section on Developmental and Behavioral Pediatrics and Council on Children with Disabilities, the Society for Developmental and Behavioral Pediatrics, and the National Association of Pediatric Nurse Practitioners Developmental and Behavioral Mental Health Special Interest Group. RESULTS: The response rate was 48%. There were 411 fellowship-trained physicians, 147 nonfellowship-trained physicians, and 125 nurse practitioners; 61% were women, 79% were white, and 5% were Hispanic. Physicians had a mean of 29 years since medical school graduation, and one-third planned to retire in 3 to 5 years. Nurse practitioners were earlier in their careers. Respondents reported long wait times for new appointments, clinician burnout, increased patient complexity and up to 50% additional time spent per visit in nonreimbursed clinical-care activities. Female subspecialists spent more time per visit in billable and nonbillable components of clinical care. CONCLUSIONS: The DBP workforce struggles to meet current service demands, with long waits for appointments, increased complexity, and high volumes of nonreimbursed care. Sex-based practice differences must be considered in future planning. The viability of the DBP subspecialty requires strategies to maintain and expand the workforce, improve clinical efficiency, and prevent burnout.

AB - OBJECTIVE: To evaluate the statistical parametric mapping (SPM) procedure for fluorodeoxyglucose (FDG)-PET imaging as a possible single-subject marker of progression to dementia in Parkinson disease (PD). METHODS: Fifty-four consecutive patients with PD without dementia (age at onset of 59.9 +/- 10.1 years, disease duration of 5.3 +/- 3.4 years) entered the study. The patients underwent an extensive motor and cognitive assessment and a single-subject FDG PET SPM evaluation at baseline. A 4-year follow-up provided disease progression and dementia diagnosis. RESULTS: The FDG-PET SPM was evaluated by 2 expert raters allowing the identification of a "typical PD pattern" in 29 patients, whereas 25 patients presented with "atypical patterns," namely, dementia with Lewy bodies (DLB)-like (n = 12), Alzheimer disease (AD)-like (n = 6), corticobasal syndrome (CBS)-like (n = 5), and frontotemporal dementia (FTD)-like (n = 2). At 4-year follow-up, 13 patients, all showing atypical brain metabolic patterns at baseline, progressed to dementia (PD dementia). The DLB- and AD-like SPM patterns were the best predictor for incident dementia (p < 0.005, sensitivity 85%, specificity 88%), independently from demographics or cognitive baseline classification. CONCLUSIONS: This study suggests that FDG-PET SPM at the single subject level might help in identifying patients with PD at risk of developing dementia. PMID- 29453243 TI - Peak perihemorrhagic edema correlates with functional outcome in intracerebral hemorrhage. AB - OBJECTIVE: To evaluate the association of perihemorrhagic edema (PHE) evolution and peak edema extent with day 90 functional outcome in patients with intracerebral hemorrhage (ICH) and identify pathophysiologic factors influencing edema evolution. METHODS: This retrospective cohort study included patients with spontaneous supratentorial ICH between January 2006 and January 2014. ICH and PHE volumes were studied using a validated semiautomatic volumetric algorithm. Multivariable logistic regression and propensity score matching (PSM) accounting for age, ICH volume, and location were used for assessing measures associated with functional outcome and PHE evolution. Clinical outcome on day 90 was assessed using the modified Rankin Scale (0-3 = favorable, 4-6 = poor). RESULTS: A total of 292 patients were included. Median age was 70 years (interquartile range [IQR] 62-78), median ICH volume on admission 17.7 mL (IQR 7.9-40.2). Besides established factors for functional outcome, i.e., ICH volume and location, age, intraventricular hemorrhage, and NIH Stroke Scale score on admission, multivariable logistic regression revealed peak PHE volume (odds ratio [OR] 0.984 [95% confidence interval (CI) 0.973-0.994]) as an independent predictor of day 90 outcome. Peak PHE volume was independently associated with initial PHE increase up to day 3 (OR 1.060 [95% CI 1.018-1.103]) and neutrophil to lymphocyte ratio on day 6 (OR 1.236 [95% CI 1.034-1.477; PSM cohort, n = 124]). Initial PHE increase (PSM cohort, n = 224) was independently related to hematoma expansion (OR 3.647 [95% CI 1.533-8.679]) and fever burden on days 2-3 (OR 1.456 [95% CI 1.103-1.920]). CONCLUSION: Our findings suggest that peak PHE volume represents an independent predictor of functional outcome after ICH. Inflammatory processes and hematoma expansion seem to be involved in PHE evolution and may represent important treatment targets.

AB - OBJECTIVE: To identify the white matter correlates of apathy and impulsivity in the major syndromes associated with frontotemporal lobar degeneration, using diffusion-weighted imaging and data from the PiPPIN (Pick's Disease and Progressive Supranuclear Palsy: Prevalence and Incidence) study. We included behavioral and language variants of frontotemporal dementia, corticobasal syndrome, and progressive supranuclear palsy. METHODS: Seventy patients and 30 controls underwent diffusion tensor imaging at 3-tesla after detailed assessment of apathy and impulsivity. We used tract-based spatial statistics of fractional anisotropy and mean diffusivity, correlating with 8 orthogonal dimensions of apathy and impulsivity derived from a principal component analysis of neuropsychological, behavioral, and questionnaire measures. RESULTS: Three components were associated with significant white matter tract abnormalities. Carer-rated change in everyday skills, self-care, and motivation correlated with widespread changes in dorsal frontoparietal and corticospinal tracts, while carer observations of impulsive-apathetic and challenging behaviors revealed disruption in ventral frontotemporal tracts. Objective neuropsychological tests of cognitive control, reflection impulsivity, and reward responsiveness were associated with focal changes in the right frontal lobe and presupplementary motor area. These changes were observed across clinical diagnostic groups, and were not restricted to the disorders for which diagnostic criteria include apathy and impulsivity. CONCLUSION: The current study provides evidence of distinct structural network changes in white matter associated with different neurobehavioral components of apathy and impulsivity across the diverse spectrum of syndromes and pathologies associated with frontotemporal lobar degeneration. PMID- 29453245 TI - Early vs late age at onset frontotemporal dementia and frontotemporal lobar degeneration. AB - OBJECTIVE: To examine clinicopathologic correlations in early vs late age at onset frontotemporal dementia (FTD) and frontotemporal lobar degeneration (FTLD). METHODS: All patients were clinically evaluated and prospectively diagnosed at the UCSF Memory and Aging Center. Two consecutive series were included: (1) patients with a clinically diagnosed FTD syndrome who underwent autopsy (cohort 1) and (2) patients with a primary pathologic diagnosis of FTLD, regardless of the clinical syndrome (cohort 2). These series were divided by age at symptom onset (cutoff 65 years). RESULTS: In cohort 1, 48 (25.3%) were 65 years or older at symptom onset. Pathologic causes of behavioral variant FTD (bvFTD) were similar in the early age at onset (EO) and late age at onset (LO) bvFTD groups. In corticobasal syndrome (CBS), however, the most common pathologic substrate differed according to age at onset: progressive supranuclear palsy (42.9%) in LO CBS and Alzheimer disease (AD; 40.7%) in EO-CBS. In cohort 2, 57 (28.4%) were classified as LO-FTLD. Regarding FTLD major molecular classes, FTLD with transactive response DNA-binding protein of 43 kDa was most common in EO-FTLD (44.4%), whereas FTLD-tau (58.3%) was most common in LO-FTLD. Antemortem diagnosis of a non-FTD syndrome, usually AD-type dementia, was more frequent in LO-FTLD than EO-FTLD (19.3% vs 7.7%, p = 0.017). LO-FTLD was also associated with more prevalent comorbid pathologic changes. Of these, moderate to severe AD neuropathologic change and argyrophilic grain disease were overrepresented among patients who received an antemortem diagnosis of AD-type dementia. CONCLUSION: Patients with FTD and FTLD often develop symptoms after age 65, and age at onset represents an important consideration when making antemortem neuropathologic predictions. PMID- 29453246 TI - Yield of the RYR2 Genetic Test in Suspected Catecholaminergic Polymorphic Ventricular Tachycardia and Implications for Test Interpretation. AB - BACKGROUND: Pathogenic RYR2 variants account for ~60% of clinically definite cases of catecholaminergic polymorphic ventricular tachycardia. However, the rate of rare benign RYR2 variants identified in the general population remains a challenge for genetic test interpretation. Therefore, we examined the results of the RYR2 genetic test among patients referred for commercial genetic testing and examined factors impacting variant interpretability. METHODS: Frequency and location comparisons were made for RYR2 variants identified among 1355 total patients of varying clinical certainty and 60 706 Exome Aggregation Consortium controls. The impact of the clinical phenotype on the yield of RYR2 variants was examined. Six in silico tools were assessed using patient- and control-derived variants. RESULTS: A total of 18.2% (218/1200) of patients referred for commercial testing hosted rare RYR2 variants, statistically less than the 59% (46/78) yield among clinically definite cases, resulting in a much higher potential genetic false discovery rate among referrals considering the 3.2% background rate of rare, benign RYR2 variants. Exclusion of clearly putative pathogenic variants further complicates the interpretation of the next novel RYR2 variant. Exonic/topologic analyses revealed overrepresentation of patient variants in exons covering only one third of the protein. In silico tools largely failed to show evidence toward enhancement of variant interpretation. CONCLUSIONS: Current expert recommendations have resulted in increased use of RYR2 genetic testing in patients with questionable clinical phenotypes. Using the largest to date catecholaminergic polymorphic ventricular tachycardia patient versus control comparison, this study highlights important variables in the interpretation of variants to overcome the 3.2% background rate that confounds RYR2 variant interpretation.

PMID- 29453249 TI - Hhex induces promyelocyte self-renewal and cooperates with growth factor independence to cause myeloid leukemia in mice. AB - The hematopoietically expressed homeobox (Hhex) transcription factor is overexpressed in human myeloid leukemias. Conditional knockout models of murine acute myeloid leukemia indicate that Hhex maintains leukemia stem cell self renewal by enabling Polycomb-mediated epigenetic repression of the Cdkn2a tumor suppressor locus, encoding p16Ink4a and p19Arf However, whether Hhex overexpression also affects hematopoietic differentiation is unknown. To study this, we retrovirally overexpressed Hhex in hematopoietic progenitors. This enabled serial replating of myeloid progenitors, leading to the rapid establishment of interleukin-3 (IL-3)-dependent promyelocytic cell lines. Use of a Hhex-ERT2 fusion protein demonstrated that continuous nuclear Hhex is required for transformation, and structure function analysis demonstrated a requirement of the DNA-binding and N-terminal-repressive domains of Hhex for promyelocytic transformation. This included the N-terminal promyelocytic leukemia protein (Pml) interaction domain, although deletion of Pml failed to prevent Hhex-induced promyelocyte transformation, implying other critical partners. Furthermore, deletion of p16Ink4a or p19Arf did not promote promyelocyte transformation, indicating that repression of distinct Hhex target genes is required for this process. Indeed, transcriptome analysis showed that Hhex overexpression resulted in repression of several myeloid developmental genes. To test the potential for Hhex overexpression to contribute to leukemic transformation, Hhex-transformed promyelocyte lines were rendered growth factor-independent using a constitutively active IL-3 receptor common beta subunit (betacV449E). The resultant cell lines resulted in a rapid promyelocytic leukemia in vivo. Thus, Hhex overexpression can contribute to myeloid leukemia via multiple mechanisms including differentiation blockade and enabling epigenetic repression of the Cdkn2a locus. PMID- 29453250 TI - Retinal-chitosan Conjugates Effectively Deliver Active Chromophores to Retinal Photoreceptor Cells in Blind Mice and Dogs. AB - The retinoid (visual) cycle consists of a series of biochemical reactions needed to regenerate the visual chromophore 11-cis-retinal and sustain vision. Genetic or environmental factors affecting chromophore production can lead to blindness. Using animal models that mimic human retinal diseases, we previously demonstrated that mechanism-based pharmacological interventions can maintain vision in otherwise incurable genetic diseases of the retina. Here, we report that after 9 cis-retinal administration to lecithin:retinol acyltransferase-deficient (Lrat-/- ) mice, the drug was rapidly absorbed and then cleared within 1 to 2 hours. However, when conjugated to form chitosan-9-cis-retinal, this prodrug was slowly absorbed from the gastrointestinal tract, resulting in sustainable plasma levels of 9-cis-retinol and recovery of visual function without causing elevated levels, as occurs with unconjugated drug treatment. Administration of chitosan-9-cis retinal conjugate intravitreally in retinal pigment epithelium-specific 65 retinoid isomerase (RPE65)-deficient dogs improved photoreceptor function as assessed by electroretinography. Functional rescue was dose dependent and maintained for several weeks. Dosing via the gastrointestinal tract in canines was found ineffective, most likely due to peculiarities of vitamin A blood transport in canines. Use of the chitosan conjugate in combination with 11-cis-6 ring-retinal, a locked ring analog of 11-cis-retinal that selectively blocks rod opsin consumption of chromophore while largely sparing cone opsins, was found to prolong cone vision in Lrat-/- mice. Development of such combination low-dose regimens to selectively prolong useful cone vision could not only expand retinal disease treatments to include Leber congenital amaurosis but also the age-related decline in human dark adaptation from progressive retinoid cycle deficiency. PMID- 29453251 TI - Novel Adipokine, FAM19A5, Inhibits Neointima Formation After Injury Through Sphingosine-1-Phosphate Receptor 2. AB - BACKGROUND: Obesity plays crucial roles in the development of cardiovascular diseases. However, the mechanisms that link obesity and cardiovascular diseases remain elusive. Compelling evidence indicates that adipokines play an important role in obesity-related cardiovascular diseases. Here, we found a new adipokine named family with sequence similarity 19, member A5 (FAM19A5), a protein with unknown function that was predicted to be distantly related to the CC-chemokine family. We aimed to test whether adipose-derived FAM19A5 regulates vascular pathology on injury. METHODS: DNA cloning, protein expression, purification, and N-terminal sequencing were applied to characterize FAM19A5. Adenovirus infection and siRNA transfection were performed to regulate FAM19A5 expression. Balloon and wire injury were performed in vivo on the rat carotid arteries and mouse femoral arteries, respectively. Bioinformatics analysis, radioactive ligand-receptor binding assays, receptor internalization, and calcium mobilization assays were used to identify the functional receptor for FAM19A5. RESULTS: We first characterized FAM19A5 as a secreted protein, and the first 43 N-terminal amino acids were the signal peptides. Both FAM19A5 mRNA and protein were abundantly expressed in the adipose tissue but were downregulated in obese mice. Overexpression of FAM19A5 markedly inhibited vascular smooth muscle cell proliferation and migration and neointima formation in the carotid arteries of balloon-injured rats. Accordingly, FAM19A5 silencing in adipocytes significantly promoted vascular smooth muscle cell activation. Adipose-specific FAM19A5 transgenic mice showed greater attenuation of neointima formation compared with wild-type littermates fed with or without Western-style diet. We further revealed that sphingosine-1-phosphate receptor 2 was the functional receptor for FAM19A5, with a dissociation constant (Kd) of 0.634 nmol/L. Inhibition of sphingosine-1 phosphate receptor 2 or its downstream G12/13-RhoA signaling circumvented the suppressive effects of FAM19A5 on vascular smooth muscle cell proliferation and migration. CONCLUSIONS: We revealed that a novel adipokine, FAM19A5, was capable of inhibiting postinjury neointima formation via sphingosine-1-phosphate receptor 2-G12/13-RhoA signaling. Downregulation of FAM19A5 during obesity may trigger cardiometabolic diseases. PMID- 29453252 TI - Ecology and Biotechnological Potential of Bacteria Belonging to the Genus Pseudovibrio. AB - Members of the genus Pseudovibrio have been isolated worldwide from a great variety of marine sources as both free-living and host-associated bacteria. So far, the available data depict a group of alphaproteobacteria characterized by a versatile metabolism, which allows them to use a variety of substrates to meet their carbon, nitrogen, sulfur, and phosphorous requirements. Additionally, Pseudovibrio-related bacteria have been shown to proliferate under extreme oligotrophic conditions, tolerate high heavy-metal concentrations, and metabolize potentially toxic compounds. Considering this versatility, it is not surprising that they have been detected from temperate to tropical regions and are often the most abundant isolates obtained from marine invertebrates. Such an association is particularly recurrent with marine sponges and corals, animals that play a key role in benthic marine systems. The data so far available indicate that these bacteria are mainly beneficial to the host, and besides being involved in major nutrient cycles, they could provide the host with both vitamins/cofactors and protection from potential pathogens via the synthesis of antimicrobial secondary metabolites. In fact, the biosynthetic abilities of Pseudovibrio spp. have been emerging in recent years, and both genomic and analytic studies have underlined how these organisms promise novel natural products of biotechnological value. PMID- 29453253 TI - Assembly of Synthetic Functional Cellulosomal Structures onto the Cell Surface of Lactobacillus plantarum, a Potent Member of the Gut Microbiome. AB - Heterologous display of enzymes on microbial cell surfaces is an extremely desirable approach, since it enables the engineered microbe to interact directly with the plant wall extracellular polysaccharide matrix. In recent years, attempts have been made to endow noncellulolytic microbes with genetically engineered cellulolytic capabilities for improved hydrolysis of lignocellulosic biomass and for advanced probiotics. Thus far, however, owing to the hurdles encountered in secreting and assembling large, intricate complexes on the bacterial cell wall, only free cellulases or relatively simple cellulosome assemblies have been introduced into live bacteria. Here, we employed the "adaptor scaffoldin" strategy to compensate for the low levels of protein displayed on the bacterial cell surface. That strategy mimics natural elaborated cellulosome architectures, thus exploiting the exponential features of their Lego like combinatorics. Using this approach, we produced several bacterial consortia of Lactobacillus plantarum, a potent gut microbe which provides a very robust genetic framework for lignocellulosic degradation. We successfully engineered surface display of large, fully active self-assembling cellulosomal complexes containing an unprecedented number of catalytic subunits all produced in vivo by the cell consortia. Our results demonstrate that the enzyme stability and performance of the cellulosomal machinery, which are superior to those seen with the equivalent secreted free enzyme system, and the high cellulase-to-xylanase ratios proved beneficial for efficient degradation of wheat straw.IMPORTANCE The multiple benefits of lactic acid bacteria are well established in health and industry. Here we present an approach designed to extensively increase the cell surface display of proteins via successive assembly of interactive components. Our findings present a stepping stone toward proficient engineering of Lactobacillus plantarum, a widespread, environmentally important bacterium and potent microbiome member, for improved degradation of lignocellulosic biomass and advanced probiotics. PMID- 29453254 TI - Versatile Cas9-Driven Subpopulation Selection Toolbox for Lactococcus lactis. AB - CRISPR-Cas9 technology has been exploited for the removal or replacement of genetic elements in a wide range of prokaryotes and eukaryotes. Here, we describe the extension of the Cas9 application toolbox to the industrially important dairy species Lactococcus lactis The Cas9 expression vector pLABTarget, encoding the Streptocccus pyogenes Cas9 under the control of a constitutive promoter, was constructed, allowing plug and play introduction of short guide RNA (sgRNA) sequences to target specific genetic loci. Introduction of a pepN-targeting derivative of pLABTarget into L. lactis strain MG1363 led to a strong reduction in the number of transformants obtained, which did not occur in a pepN deletion derivative of the same strain, demonstrating the specificity and lethality of the Cas9-mediated double-strand breaks in the lactococcal chromosome. Moreover, the same pLABTarget derivative allowed the selection of a pepN deletion subpopulation from its corresponding single-crossover plasmid integrant precursor, accelerating the construction and selection of gene-specific deletion derivatives in L. lactis Finally, pLABTarget, which contained sgRNAs designed to target mobile genetic elements, allowed the effective curing of plasmids, prophages, and integrative conjugative elements (ICEs). These results establish that pLABTarget enables the effective exploitation of Cas9 targeting in L. lactis, while the broad-host-range vector used suggests that this toolbox could readily be expanded to other Gram positive bacteria.IMPORTANCE Mobile genetic elements in Lactococcus lactis and other lactic acid bacteria (LAB) play an important role in dairy fermentation, having both positive and detrimental effects during the production of fermented dairy products. The pLABTarget vector offers an efficient cloning platform for Cas9 application in lactic acid bacteria. Targeting Cas9 toward mobile genetic elements enabled their effective curing, which is of particular interest in the context of potentially problematic prophages present in a strain. Moreover, Cas9 targeting of other mobile genetic elements enables the deciphering of their contribution to dairy fermentation processes and further establishment of their importance for product characteristics. PMID- 29453255 TI - Endophyte-Mediated Modulation of Defense-Related Genes and Systemic Resistance in Withania somnifera (L.) Dunal under Alternaria alternata Stress. AB - Endophytes have been explored and found to perform an important role in plant health. However, their effects on the host physiological function and disease management remain elusive. The present study aimed to assess the potential effects of endophytes, singly as well as in combination, in Withania somnifera (L.) Dunal, on various physiological parameters and systemic defense mechanisms against Alternaria alternata Seeds primed with the endophytic bacteria Bacillus amyloliquefaciens and Pseudomonas fluorescens individually and in combination demonstrated an enhanced vigor index and germination rate. Interestingly, plants treated with the two-microbe combination showed the lowest plant mortality rate (28%) under A. alternata stress. Physiological profiling of treated plants showed improved photosynthesis, respiration, transpiration, and stomatal conductance under pathogenic stress. Additionally, these endophytes not only augmented defense enzymes and antioxidant activity in treated plants but also enhanced the expression of salicylic acid- and jasmonic acid-responsive genes in the stressed plants. Reductions in reactive oxygen species (ROS) and reactive nitrogen species (RNS) along with enhanced callose deposition in host plant leaves corroborated well with the above findings. Altogether, the study provides novel insights into the underlying mechanisms behind the tripartite interaction of endophyte-A. alternata-W. somnifera and underscores their ability to boost plant health under pathogen stress.IMPORTANCEW. somnifera is well known for producing several medicinally important secondary metabolites. These secondary metabolites are required by various pharmaceutical sectors to produce life-saving drugs. However, the cultivation of W. somnifera faces severe challenge from leaf spot disease caused by A. alternata To keep pace with the rising demand for this plant and considering its capacity for cultivation under field conditions, the present study was undertaken to develop approaches to enhance production of W. somnifera through intervention using endophytes. Application of bacterial endophytes not only suppresses the pathogenicity of A. alternata but also mitigates excessive ROS/RNS generation via enhanced physiological processes and antioxidant machinery. Expression profiling of plant defense-related genes further validates the efficacy of bacterial endophytes against leaf spot disease. PMID- 29453256 TI - Structural Characterization and Directed Evolution of a Novel Acetyl Xylan Esterase Reveals Thermostability Determinants of the Carbohydrate Esterase 7 Family. AB - A hot desert hypolith metagenomic DNA sequence data set was screened in silico for genes annotated as acetyl xylan esterases (AcXEs). One of the genes identified encoded an ~36-kDa protein (Axe1NaM1). The synthesized gene was cloned and expressed, and the resulting protein was purified. NaM1 was optimally active at pH 8.5 and 30 degrees C and functionally stable at salt concentrations of up to 5 M. The specific activity and catalytic efficiency were 488.9 U mg-1 and 3.26 * 106 M-1 s-1, respectively. The crystal structure of wild-type NaM1 was solved at a resolution of 2.03 A, and a comparison with the structures and models of more thermostable carbohydrate esterase 7 (CE7) family enzymes and variants of NaM1 from a directed evolution experiment suggests that reduced side-chain volume of protein core residues is relevant to the thermal stability of NaM1. Surprisingly, a single point mutation (N96S) not only resulted in a simultaneous improvement in thermal stability and catalytic efficiency but also increased the acyl moiety substrate range of NaM1.IMPORTANCE AcXEs belong to nine carbohydrate esterase families (CE1 to CE7, CE12, and CE16), of which CE7 enzymes possess a unique and narrow specificity for acetylated substrates. All structurally characterized members of this family are moderately to highly thermostable. The crystal structure of a novel, mesophilic CE7 AcXE (Axe1NaM1), from a soil metagenome, provides a basis for comparisons with thermostable CE7 enzymes. Using error-prone PCR and site-directed mutagenesis, we enhanced both the stability and activity of the mesophilic AcXE. With comparative structural analyses, we have also identified possible thermal stability determinants. These are valuable for understanding the thermal stability of enzymes within this family and as a guide for future protein engineering of CE7 and other alpha/beta hydrolase enzymes. PMID- 29453257 TI - Facile Arsenazo III-Based Assay for Monitoring Rare Earth Element Depletion from Cultivation Media for Methanotrophic and Methylotrophic Bacteria. AB - Recently, methanotrophic and methylotrophic bacteria were found to utilize rare earth elements (REEs). To monitor the REE content in culture media of these bacteria, we have developed a rapid screening method using the Arsenazo III (AS III) dye for spectrophotometric REE detection in the low MUM (0.1 to 10 MUM) range. We designed this assay to follow LaIII and EuIII depletion from the culture medium by the acidophilic verrucomicrobial methanotroph Methylacidiphilum fumariolicum strain SolV. The assay can also be modified to screen the uptake of other REEs, such as PrIII, or to monitor the depletion of LaIII from growth media in neutrophilic methylotrophs such as Methylobacterium extorquens strain AM1. The AS III assay presents a convenient and fast detection method for REE levels in culture media and is a sensitive alternative to inductively coupled plasma mass spectrometry (ICP-MS) or atomic absorption spectroscopy (AAS).IMPORTANCE REE dependent bacterial metabolism is a quickly emerging field, and while the importance of REEs for both methanotrophic and methylotrophic bacteria is now firmly established, many important questions, such as how these insoluble elements are taken up into cells, are still unanswered. Here, an Arsenazo III dye based assay has been developed for fast, specific, and sensitive determination of REE content in different culture media. This assay presents a useful tool for optimizing cultivation protocols, as well as for routine REE monitoring during bacterial growth without the need for specialized analytical instrumentation. Furthermore, this assay has the potential to promote the discovery of other REE dependent microorganisms and can help to elucidate the mechanisms for acquisition of REEs by methanotrophic and methylotrophic bacteria. PMID- 29453258 TI - Anthropogenic N Deposition Alters the Composition of Expressed Class II Fungal Peroxidases. AB - Here, we present evidence that ca. 20 years of experimental N deposition altered the composition of lignin-decaying class II peroxidases expressed by forest floor fungi, a response which has occurred concurrently with reductions in plant litter decomposition and a rapid accumulation of soil organic matter. This finding suggests that anthropogenic N deposition has induced changes in the biological mediation of lignin decay, the rate limiting step in plant litter decomposition. Thus, an altered composition of transcripts for a critical gene that is associated with terrestrial C cycling may explain the increased soil C storage under long-term increases in anthropogenic N deposition.IMPORTANCE Fungal class II peroxidases are enzymes that mediate the rate-limiting step in the decomposition of plant material, which involves the oxidation of lignin and other polyphenols. In field experiments, anthropogenic N deposition has increased soil C storage in forests, a result which could potentially arise from anthropogenic N induced changes in the composition of class II peroxidases expressed by the fungal community. In this study, we have gained unique insight into how anthropogenic N deposition, a widespread agent of global change, affects the expression of a functional gene encoding an enzyme that plays a critical role in a biologically mediated ecosystem process. PMID- 29453259 TI - Common Hydraulic Fracturing Fluid Additives Alter the Structure and Function of Anaerobic Microbial Communities. AB - The development of unconventional oil and gas (UOG) resources results in the production of large volumes of wastewater containing a complex mixture of hydraulic fracturing chemical additives and components from the formation. The release of these wastewaters into the environment poses potential risks that are poorly understood. Microbial communities in stream sediments form the base of the food chain and may serve as sentinels for changes in stream health. Iron-reducing organisms have been shown to play a role in the biodegradation of a wide range of organic compounds, and so to evaluate their response to UOG wastewater, we enriched anaerobic microbial communities from sediments collected upstream (background) and downstream (impacted) of an UOG wastewater injection disposal facility in the presence of hydraulic fracturing fluid (HFF) additives: guar gum, ethylene glycol, and two biocides, 2,2-dibromo-3-nitrilopropionamide (DBNPA) and bronopol (C3H6BrNO4). Iron reduction was significantly inhibited early in the incubations with the addition of biocides, whereas amendment with guar gum and ethylene glycol stimulated iron reduction relative to levels in the unamended controls. Changes in the microbial community structure were observed across all treatments, indicating the potential for even small amounts of UOG wastewater components to influence natural microbial processes. The microbial community structure differed between enrichments with background and impacted sediments, suggesting that impacted sediments may have been preconditioned by exposure to wastewater. These experiments demonstrated the potential for biocides to significantly decrease iron reduction rates immediately following a spill and demonstrated how microbial communities previously exposed to UOG wastewater may be more resilient to additional spills.IMPORTANCE Organic components of UOG wastewater can alter microbial communities and biogeochemical processes, which could alter the rates of essential natural attenuation processes. These findings provide new insights into microbial responses following a release of UOG wastewaters and are critical for identifying strategies for the remediation and natural attenuation of impacted environments. PMID- 29453260 TI - A new cell extraction method reveals hemolymph microbiome of three aquatic invertebrates. AB - Symbiotic microorganisms have been found in the hemolymph (blood) of many aquatic invertebrates, such as crabs, shrimps and oysters. Hemolymph is a critical site in host immune response. Currently, studies on hemolymph microorganisms are mostly performed with culture-dependent strategies using selective media (e.g., TCBS, 2216E, and LB) for enumerating and isolating microbial cells. However, doubts remain about the "true" representation of the microbial abundance and diversity of symbiotic microorganisms in hemolymph, particularly for uncultivable microorganisms which are believed to be more abundant than the cultured. To explore this, we developed a culture-independent cell extraction method for separating microbial cells from the hemolymph of three aquatic invertebrates (Scylla paramamosain, Litopenaeus vannamei, and Crassostrea angulata) involving filtration through a 5-MUm mesh filter membrane (the Filtration Method). A combination of the Filtration Method with fluorescence microscopy and high throughput sequencing technique provides insight into the abundances and diversity of the total microbiota in the hemolymph of these three invertebrates. More than 2.6 * 104 cells/mL of microbial cells dominated by Escherichia-Shigella and Halomonas, Photobacterium and Escherichia-Shigella, and Pseudoalteromonas and Arcobacter, were detected in the hemolymph of Scylla paramamosain, Litopenaeus vannamei, and Crassostrea angulata, respectively. A parallel study for investigating the hemolymph microbiome by comparing the Filtration Method and a culture-dependent method (the Plate Count Method), showed significantly higher microbial abundances (between 26 and 369-folds difference; P<0.05) and less biased community structures of the Filtration Method than those of the Plate Count Method. Furthermore, hemolymph of the three invertebrates harbored many potential pathogens, including Photobacterium, Arcobacter, and Vibrio Finally, the Filtration Method provides a solution that improves understanding of the metabolic functions of uncultivable hemolymph microorganisms (e.g., metagenomics) devoid of host hemocytes contamination.Importance Microorganisms are found in invertebrates' hemolymph, a critical site in host immune response. Currently, studies on hemolymph microorganisms are mostly performed with culture-dependent strategies. However, doubts remain about the "true" representation of hemolymph microbiome. This study developed a culture-independent cell extraction method that could separate microbial cells from the hemolymph of three aquatic invertebrates (S. paramamosain, L. vannamei, and C. angulata) based on filtration through a 5-MUm mesh filter membrane (the Filtration Method). A combination of the Filtration Method with fluorescence microscopy and high-throughput sequencing technique provides insight into the abundances and diversity of the total microbiota in the hemolymph of these three invertebrates. Our results demonstrate that the hemolymph of aquatic invertebrates harbors a much higher microbial abundance and distinct microbial community composition than previously estimated. Furthermore, this work provides a less biased solution for studying the metabolic functions of uncultivable hemolymph microbiota devoid of host hemocytes contamination. PMID- 29453261 TI - Molecular and Functional Study of a Branching Sucrase-Like Glucansucrase Reveals an Evolutionary Intermediate between Two Subfamilies of the GH70 Enzymes. AB - Glucansucrases (GSs) in glycoside hydrolase family 70 (GH70) catalyze the synthesis of alpha-glucans from sucrose, a reaction that is widely seen in lactic acid bacteria (LAB). These enzymes have been implicated in many aspects of microbial life. Products of GSs have great commercial value as food supplements and medical materials; therefore, these enzymes have attracted much attention from both science and industry. Certain issues concerning the origin and evolution of GSs are still to be addressed, although an increasing number of GH70 enzymes have been characterized. This study describes a GS enzyme with the appearance of a branching sucrase (BrS). Structural analysis indicated that this GS enzyme produced a type of glucan composed of an alpha-(1->6) glucosidic backbone and alpha-(1->4) branches, as well as a considerable amount of alpha-(1 >3) branches, distinguishing it from the GSs identified so far. Moreover, sequence-based analysis of the catalytic core of this enzyme suggested that it might be an evolutionary intermediate between the BrS and GS subgroups. These results provide an evolutionary link between these subgroups of GH70 enzymes and shed new light on the origination of GSs.IMPORTANCE GH70 GSs catalyze the synthesis of alpha-glucans from sucrose, a reaction that is widely seen in LAB. Products of these enzymes have great commercial value as food supplements and medical materials. Moreover, these enzymes have attracted much attention from scientists because they have potential in tailored synthesis of alpha-glucans with desired structures and properties. Although more and more GSs have been characterized, the origin and evolution of these enzymes have not been well addressed. This study describes a GS with the appearance of a BrS (i.e., high levels of similarity to BrSs in sequence analysis). Further analysis indicated that this enzyme synthesized a type of insoluble glucan composed of an alpha-(1 >6) glucosidic backbone and many alpha-(1->4)- and alpha-(1->3)-linked branches, the linkage composition of which has rarely been reported in the literature. This BrS-like GS enzyme might be an evolutionary intermediate between BrS and GS enzymes. PMID- 29453262 TI - Insights into the fundamental physiology of the uncultured Fe-oxidizing bacterium Leptothrix ochracea. AB - Leptothrix ochracea is known for producing large volumes of iron-oxyhydroxide sheaths that alter wetland biogeochemistry. For over a century, these delicate structures have fascinated microbiologists and geoscientists. Because L. ochracea still resists long-term in vitro culture, the debate regarding its metabolic classification dates back to 1885. We developed a novel culturing technique for L. ochracea using in situ natural waters, and coupled this with single cell genomics and nanoscale secondary ion mass spectrophotometry (nanoSIMS) to probe L. ochracea's physiology. In micro-slide cultures L. ochracea doubled every 5.7 hrs, had an absolute growth requirement for ferrous iron, had the genomic capacity for iron-oxidation, and a branched electron transport chain with cytochromes putatively involved in lithotrophic iron-oxidation. Additionally, its genome encoded several electron transport chain proteins including, a molybdopterin ACIII complex, a cytochrome bd oxidase reductase, and several terminal oxidase genes. L. ochracea contained two key autotrophic proteins in the Calvin Benson Bassham cycle, a Form II ribulose-bis-phosphate carboxylase and a phosphoribulose kinase. L. ochracea also assimilated bicarbonate, although calculations suggest bicarbonate assimilation is a small fraction of its total carbon assimilation. Finally, L. ochracea's fundamental physiology is a hybrid of the chemolithotrophic Gallionella-type iron-oxidizing bacteria and the sheathed, heterotrophic filamentous metal-oxidizing bacteria of the Leptothrix-Sphaerotilus genera. This allows L. ochracea to inhabit a unique niche within the neutrophilic iron seeps.ImportanceLeptothrix ochracea was one of three groups of organisms Sergei Winogradsky used in the 1880s to develop the hypothesis on chemolithotrophy. L. ochracea continues to resist cultivation and appears to have an absolute requirement for organic rich waters suggesting its true physiology remains unknown. Further, L. ochracea is an ecological engineer, a few L. ochracea cells can generate prodigious volumes of iron-oxyhydroxides changing the ecosystem geochemistry and ecology. Therefore, to determine Lochracea's basic physiology, we employed new single-cell techniques to demonstrate: L. ochracea oxidizes iron to generate energy and, despite predicted genes for autotrophic growth, L. ochacea assimilates a fraction of the total CO2 that autotrophs do. Although not a true chemolithoautotroph, L. ochracea's physiological strategy allows it to be flexible, extensively colonize iron-rich wetlands. PMID- 29453263 TI - Enzyme Activities of Two Recombinant Heme-Containing Peroxidases, TvDyP1 and TvVP2, Identified from the Secretome of Trametes versicolor. AB - Trametesversicolor is a wood-inhabiting agaricomycete known for its ability to cause strong white-rot decay on hardwood and for its high tolerance of phenolic compounds. The goal of the present work was to gain insights into the molecular biology and biochemistry of the heme-including class II and dye-decolorizing peroxidases secreted by this fungus. Proteomic analysis of the secretome of T. versicolor BRFM 1218 grown on oak wood revealed a set of 200 secreted proteins, among which were the dye-decolorizing peroxidase TvDyP1 and the versatile peroxidase TvVP2. Both peroxidases were heterologously produced in Escherichia coli, biochemically characterized, and tested for the ability to oxidize complex substrates. Both peroxidases were found to be active against several substrates under acidic conditions, and TvDyP1 was very stable over a relatively large pH range of 2.0 to 6.0, while TvVP2 was more stable at pH 5.0 to 6.0 only. The thermostability of both enzymes was also tested, and TvDyP1 was globally found to be more stable than TvVP2. After 180 min of incubation at temperatures ranging from 30 to 50 degrees C, the activity of TvVP2 drastically decreased, with 10 to 30% of the initial activity retained. Under the same conditions, TvDyP1 retained 20 to 80% of its enzyme activity. The two proteins were catalytically characterized, and TvVP2 was shown to accept a wider range of reducing substrates than TvDyP1. Furthermore, both enzymes were found to be active against two flavonoids, quercetin and catechin, found in oak wood, with TvVP2 displaying more rapid oxidation of the two compounds. They were tested for the ability to decolorize five industrial dyes, and TvVP2 presented a greater ability to oxidize and decolorize the dye substrates than TvDyP1.IMPORTANCETrametesversicolor is a wood-inhabiting agaricomycete known for its ability to cause strong white-rot decay on hardwood and for its high tolerance of phenolic compounds. Among white rot fungi, the basidiomycete T. versicolor has been extensively studied for its ability to degrade wood, specifically lignin, thanks to an extracellular oxidative enzymatic system. The corresponding oxidative system was previously studied in several works for classical lignin and manganese peroxidases, and in this study, two new components of the oxidative system of T. versicolor, one dye decolorizing peroxidase and one versatile peroxidase, were biochemically characterized in depth and compared to other fungal peroxidases. PMID- 29453264 TI - Bacterial Community Shift and Coexisting/Coexcluding Patterns Revealed by Network Analysis in a Uranium-Contaminated Site after Bioreduction Followed by Reoxidation. AB - A site in Oak Ridge, TN, USA, has sediments that contain >3% iron oxides and is contaminated with uranium (U). The U(VI) was bioreduced to U(IV) and immobilized in situ through intermittent injections of ethanol. It then was allowed to reoxidize via the invasion of low-pH (3.6 to 4.0), high-nitrate (up to 200 mM) groundwater back into the reduced zone for 1,383 days. To examine the biogeochemical response, high-throughput sequencing and network analysis were applied to characterize bacterial population shifts, as well as cooccurrence and coexclusion patterns among microbial communities. A paired t test indicated no significant changes of alpha-diversity for the bioactive wells. However, both nonmetric multidimensional scaling and analysis of similarity confirmed a significant distinction in the overall composition of the bacterial communities between the bioreduced and the reoxidized sediments. The top 20 major genera accounted for >70% of the cumulative contribution to the dissimilarity in the bacterial communities before and after the groundwater invasion. Castellaniella had the largest dissimilarity contribution (17.7%). For the bioactive wells, the abundance of the U(VI)-reducing genera Geothrix, Desulfovibrio, Ferribacterium, and Geobacter decreased significantly, whereas the denitrifying Acidovorax abundance increased significantly after groundwater invasion. Additionally, seven genera, i.e., Castellaniella, Ignavibacterium, Simplicispira, Rhizomicrobium, Acidobacteria Gp1, Acidobacteria Gp14, and Acidobacteria Gp23, were significant indicators of bioactive wells in the reoxidation stage. Canonical correspondence analysis indicated that nitrate, manganese, and pH affected mostly the U(VI) reducing genera and indicator genera. Cooccurrence patterns among microbial taxa suggested the presence of taxa sharing similar ecological niches or mutualism/commensalism/synergism interactions.IMPORTANCE High-throughput sequencing technology in combination with a network analysis approach were used to investigate the stabilization of uranium and the corresponding dynamics of bacterial communities under field conditions with regard to the heterogeneity and complexity of the subsurface over the long term. The study also examined diversity and microbial community composition shift, the common genera, and indicator genera before and after long-term contaminated-groundwater invasion and the relationship between the target functional community structure and environmental factors. Additionally, deciphering cooccurrence and coexclusion patterns among microbial taxa and environmental parameters could help predict potential biotic interactions (cooperation/competition), shared physiologies, or habitat affinities, thus, improving our understanding of ecological niches occupied by certain specific species. These findings offer new insights into compositions of and associations among bacterial communities and serve as a foundation for future bioreduction implementation and monitoring efforts applied to uranium-contaminated sites. PMID- 29453265 TI - Integrated Metabolomics and Morphogenesis Reveal Volatile Signaling of the Nematode-Trapping Fungus Arthrobotrys oligospora. AB - The adjustment of metabolic patterns is fundamental to fungal biology and plays vital roles in adaptation to diverse ecological challenges. Nematode-trapping fungi can switch their lifestyle from saprophytic to pathogenic by developing specific trapping devices induced by nematodes to infect their prey as a response to nutrient depletion in nature. However, the chemical identity of the specific fungal metabolites used during the switch remains poorly understood. We hypothesized that these important signal molecules might be volatile in nature. Gas chromatography-mass spectrometry was used to carry out comparative analysis of fungal metabolomics during the saprophytic and pathogenic lifestyles of the model species Arthrobotrys oligospora Two media commonly used in research on this species, cornmeal agar (CMA) and potato dextrose agar (PDA), were chosen for use in this study. The fungus produced a small group of volatile furanone and pyrone metabolites that were associated with the switch from the saprophytic to the pathogenic stage. A. oligospora fungi grown on CMA tended to produce more traps and employ attractive furanones to improve the utilization of traps, while fungi grown on PDA developed fewer traps and used nematode-toxic furanone metabolites to compensate for insufficient traps. Another volatile pyrone metabolite, maltol, was identified as a morphological regulator for enhancing trap formation. Deletion of the gene AOL_s00079g496 in A. oligospora led to increased amounts of the furanone attractant (2-fold) in mutants and enhanced the attractive activity (1.5-fold) of the fungus, while it resulted in decreased trap formation. This investigation provides new insights regarding the comprehensive tactics of fungal adaptation to environmental stress, integrating both morphological and metabolomic mechanisms.IMPORTANCE Nematode-trapping fungi are a unique group of soil-living fungi that can switch from the saprophytic to the pathogenic lifestyle once they come into contact with nematodes as a response to nutrient depletion. In this study, we investigated the metabolic response during the switch and the key types of metabolites involved in the interaction between fungi and nematodes. Our findings indicate that A. oligospora develops multiple and flexible metabolic tactics corresponding to different morphological responses to nematodes. A. oligospora can use similar volatile furanone and pyrone metabolites with different ecological functions to help capture nematodes in the fungal switch from the saprophytic to the pathogenic lifestyle. Furthermore, studies with A. oligospora mutants with increased furanone and pyrone metabolites confirmed the results. This investigation reveals the importance of volatile signaling in the comprehensive tactics used by nematode-trapping fungi, integrating both morphological and metabolomic mechanisms. PMID- 29453266 TI - The Gills of Reef Fish Support a Distinct Microbiome Influenced by Host-Specific Factors. AB - Teleost fish represent the most diverse of the vertebrate groups and play important roles in food webs, as ecosystem engineers, and as vectors for microorganisms. However, the microbial ecology of fishes remains underexplored for most host taxa and for certain niches on the fish body. This is particularly true for the gills, the key sites of respiration and waste exchange in fishes. Here we provide a comprehensive analysis of the gill microbiome. We focus on ecologically diverse taxa from coral reefs around Moorea, sampling the gills and intestines of adults and juveniles representing 15 families. The gill microbiome composition differed significantly from that of the gut for both adults and juveniles, with fish-associated niches having lower alpha diversity values and higher beta diversity values than those for seawater, sediment, and alga associated microbiomes. Of ~45,000 operational taxonomic units (OTUs) detected across all samples, 11% and 13% were detected only in the gill and the intestine, respectively. OTUs most enriched in the gill included members of the gammaproteobacterial genus Shewanella and the family Endozoicimonaceae In adult fish, both gill and intestinal microbiomes varied significantly among host species grouped by diet category. Gill and intestinal microbiomes from the same individual were more similar to one another than to gill and intestinal microbiomes from different individuals. These results demonstrate that distinct body sites are jointly influenced by host-specific organizing factors operating at the level of the host individual. The results also identify taxonomic signatures unique to the gill and the intestine, confirming fish-associated niches as distinct reservoirs of marine microbial diversity.IMPORTANCE Fish breathe and excrete waste through their gills. The gills are also potential sites of pathogen invasion and colonization by other microbes. However, we know little about the microbial communities that live on the gill and the factors shaping their diversity. Focusing on ecologically distinct types of coral reef fish, we provide a comprehensive analysis of the fish gill microbiome. By comparison to microbiomes of the gut and the surrounding environment, we identify microbes unique to the gill niche. These microbes may be targets for further studies to determine the contribution of the microbiome to waste exchange or host immunity. We also show that despite exhibiting a unique taxonomic signature, the gill microbiome is influenced by factors that also influence the gut microbiome. These factors include the specific identity of the host individual. These results suggest basic principles describing how association with fishes structures the composition of microbial communities. PMID- 29453267 TI - Plant-Microbe and Abiotic Factors Influencing Salmonella Survival and Growth on Alfalfa Sprouts and Swiss Chard Microgreens. AB - Microgreens, like sprouts, are relatively fast-growing products and are generally consumed raw. Moreover, as observed for sprouts, microbial contamination from preharvest sources may also be present in the production of microgreens. In this study, two Salmonella enterica serovars (Hartford and Cubana), applied at multiple inoculation levels, were evaluated for survival and growth on alfalfa sprouts and Swiss chard microgreens by using the most-probable-number (MPN) method. Various abiotic factors were also examined for their effects on Salmonella survival and growth on sprouts and microgreens. Community-level physiological profiles (CLPPs) of sprout/microgreen rhizospheres with different levels of S. enterica inoculation at different growth stages were characterized by use of Biolog EcoPlates. In the seed contamination group, the ability of S. enterica to grow on sprouting alfalfa seeds was affected by both seed storage time and inoculation level but not by serovar. However, the growth of S. enterica on Swiss chard microgreens was affected by serovar and inoculation level. Seed storage time had little effect on the average level of Salmonella populations in microgreens. In the irrigation water contamination group, the growth of Salmonella on both alfalfa sprouts and microgreens was largely affected by inoculation level. Surprisingly, the growth medium was found to play an important role in Salmonella survival and growth on microgreens. CLPP analysis showed significant changes in the microbial community metabolic diversity during sprouting for alfalfa sprouts, but few temporal changes were seen with microgreens. The data suggest that the change in rhizosphere bacterial functional diversity was dependent on the host but independent of Salmonella contamination.IMPORTANCE Sprouts and microgreens are considered "functional foods," i.e., foods containing health-promoting or disease-preventing properties in addition to normal nutritional values. However, the microbial risk associated with microgreens has not been well studied. This study evaluated Salmonella survival and growth on microgreens compared to those on sprouts, as well as other abiotic factors that could affect Salmonella survival and growth on microgreens. This work provides baseline data for risk assessment of microbial contamination of sprouts and microgreens. Understanding the risks of Salmonella contamination and its effects on rhizosphere microbial communities enables a better understanding of host-pathogen dynamics in sprouts and microgreens. The data also contribute to innovative preventive control strategies for Salmonella contamination of sprouts and microgreens.

PMID- 29453268 TI - High Microbial Diversity Promotes Soil Ecosystem Functioning. AB - In soil, the link between microbial diversity and carbon transformations is challenged by the concept of functional redundancy. Here, we hypothesized that functional redundancy may decrease with increasing carbon source recalcitrance and that coupling of diversity with C cycling may change accordingly. We manipulated microbial diversity to examine how diversity decrease affects the decomposition of easily degradable (i.e., allochthonous plant residues) versus recalcitrant (i.e., autochthonous organic matter) C sources. We found that a decrease in microbial diversity (i) affected the decomposition of both autochthonous and allochthonous carbon sources, thereby reducing global CO2 emission by up to 40%, and (ii) shaped the source of CO2 emission toward preferential decomposition of most degradable C sources. Our results also revealed that the significance of the diversity effect increases with nutrient availability. Altogether, these findings show that C cycling in soil may be more vulnerable to microbial diversity changes than expected from previous studies, particularly in ecosystems exposed to nutrient inputs. Thus, concern about the preservation of microbial diversity may be highly relevant in the current global change context assumed to impact soil biodiversity and the pulse inputs of plant residues and rhizodeposits into the soil.IMPORTANCE With hundreds of thousands of taxa per gram of soil, microbial diversity dominates soil biodiversity. While numerous studies have established that microbial communities respond rapidly to environmental changes, the relationship between microbial diversity and soil functioning remains controversial. Using a well-controlled laboratory approach, we provide empirical evidence that microbial diversity may be of high significance for organic matter decomposition, a major process on which rely many of the ecosystem services provided by the soil ecosystem. These new findings should be taken into account in future studies aimed at understanding and predicting the functional consequences of changes in microbial diversity on soil ecosystem services and carbon storage in soil.

PMID- 29453272 TI - Building the Child Safety Collaborative Innovation and Improvement Network: How does it work and what is it achieving? AB - OBJECTIVE: This study investigated whether the Child Safety Collaborative Innovation and Improvement Network (CS CoIIN) framework could be applied in the field of injury and violence prevention to reduce fatalities, hospitalizations and emergency department visits among 0-19 year olds. SAMPLE: Twenty-one states/jurisdictions were accepted into cohort 1 of the CS CoIIN, and 14 were engaged from March 2016 through April 2017. A quality improvement framework was used to test, implement and spread evidence-based change ideas (strategies and programs) in child passenger safety, falls prevention, interpersonal violence prevention, suicide and self-harm prevention and teen driver safety. PROCEDURES: Outcome and process measure data were analyzed using run chart rules. Descriptive data were analyzed for participation measures and descriptive statistics were produced. Qualitative data were analyzed to identify key themes. RESULTS: Seventy six percent of CS CoIIN states/jurisdictions were engaged in activities and used data to inform decision making. Within a year, states/jurisdictions were able to test and implement evidence-based change ideas in pilot sites. A small group showed improvement in process measures and were ready to spread change ideas. Improvement in outcome measures was not achieved; however, 25% of states/jurisdictions identified data sources and reported on real-time outcome measures. CONCLUSIONS: Evidence indicates the CS CoIIN framework can be applied to make progress on process measures, but more time is needed to determine if this will result in progress on long-term outcome measures of fatalities, hospitalizations and emergency department visits. Seventeen states/jurisdictions will participate in cohort 2. PMID- 29453273 TI - Evolution of a holistic systems approach to planning and managing road safety: the Victorian case study, 1970-2015. AB - BACKGROUND: The Victorian Safe System approach to road safety slowly evolved from a combination of the Swedish Vision Zero philosophy and the Sustainable Safety model developed by the Dutch. The Safe System approach reframes the way in which road safety is viewed and managed. METHODS: This paper presents a case study of the institutional change required to underpin the transformation to a holistic approach to planning and managing road safety in Victoria, Australia. RESULTS: The adoption and implementation of a Safe System approach require strong institutional leadership and close cooperation among all the key agencies involved, and Victoria was fortunate in that it had a long history of strong interagency mechanisms in place. However, the challenges in the implementation of the Safe System strategy in Victoria are generally neither technical nor scientific; they are predominantly social and political. While many governments purport to develop strategies based on Safe System thinking, on-the-ground action still very much depends on what politicians perceive to be publicly acceptable, and Victoria is no exception. CONCLUSIONS: This is a case study of the complexity of institutional change and is presented in the hope that the lessons may prove useful for others seeking to adopt more holistic planning and management of road safety. There is still much work to be done in Victoria, but the institutional cultural shift has taken root. Ongoing efforts must be continued to achieve alert and compliant road users; however, major underpinning benefits will be achieved through focusing on road network safety improvements (achieving forgiving infrastructure, such as wire rope barriers) in conjunction with reviews of posted speed limits (to be set in response to the level of protection offered by the road infrastructure) and by the progressive introduction into the fleet of modern vehicle safety features. PMID- 29453274 TI - Select and resequence reveals relative fitness of bacteria in symbiotic and free living environments. AB - Assays to accurately estimate relative fitness of bacteria growing in multistrain communities can advance our understanding of how selection shapes diversity within a lineage. Here, we present a variant of the "evolve and resequence" approach both to estimate relative fitness and to identify genetic variants responsible for fitness variation of symbiotic bacteria in free-living and host environments. We demonstrate the utility of this approach by characterizing selection by two plant hosts and in two free-living environments (sterilized soil and liquid media) acting on synthetic communities of the facultatively symbiotic bacterium Ensifer meliloti We find (i) selection that hosts exert on rhizobial communities depends on competition among strains, (ii) selection is stronger inside hosts than in either free-living environment, and (iii) a positive host dependent relationship between relative strain fitness in multistrain communities and host benefits provided by strains in single-strain experiments. The greatest changes in allele frequencies in response to plant hosts are in genes associated with motility, regulation of nitrogen fixation, and host/rhizobia signaling. The approach we present provides a powerful complement to experimental evolution and forward genetic screens for characterizing selection in bacterial populations, identifying gene function, and surveying the functional importance of naturally occurring genomic variation. PMID- 29453275 TI - Structure-based discovery of selective positive allosteric modulators of antagonists for the M2 muscarinic acetylcholine receptor. AB - Subtype-selective antagonists for muscarinic acetylcholine receptors (mAChRs) have long been elusive, owing to the highly conserved orthosteric binding site. However, allosteric sites of these receptors are less conserved, motivating the search for allosteric ligands that modulate agonists or antagonists to confer subtype selectivity. Accordingly, a 4.6 million-molecule library was docked against the structure of the prototypical M2 mAChR, seeking molecules that specifically stabilized antagonist binding. This led us to identify a positive allosteric modulator (PAM) that potentiated the antagonist N-methyl scopolamine (NMS). Structure-based optimization led to compound '628, which enhanced binding of NMS, and the drug scopolamine itself, with a cooperativity factor (alpha) of 5.5 and a KB of 1.1 MUM, while sparing the endogenous agonist acetylcholine. NMR spectral changes determined for methionine residues reflected changes in the allosteric network. Moreover, '628 slowed the dissociation rate of NMS from the M2 mAChR by 50-fold, an effect not observed at the other four mAChR subtypes. The specific PAM effect of '628 on NMS antagonism was conserved in functional assays, including agonist stimulation of [35S]GTPgammaS binding and ERK 1/2 phosphorylation. Importantly, the selective allostery between '628 and NMS was retained in membranes from adult rat hypothalamus and in neonatal rat cardiomyocytes, supporting the physiological relevance of this PAM/antagonist approach. This study supports the feasibility of discovering PAMs that confer subtype selectivity to antagonists; molecules like '628 can convert an armamentarium of potent but nonselective GPCR antagonist drugs into subtype selective reagents, thus reducing their off-target effects. PMID- 29453276 TI - Entropy drives selective fluorine recognition in the fluoroacetyl-CoA thioesterase from Streptomyces cattleya. AB - Fluorinated small molecules play an important role in the design of bioactive compounds for a broad range of applications. As such, there is strong interest in developing a deeper understanding of how fluorine affects the interaction of these ligands with their targets. Given the small number of fluorinated metabolites identified to date, insights into fluorine recognition have been provided almost entirely by synthetic systems. The fluoroacetyl-CoA thioesterase (FlK) from Streptomyces cattleya thus provides a unique opportunity to study an enzyme-ligand pair that has been evolutionarily optimized for a surprisingly high 106 selectivity for a single fluorine substituent. In these studies, we synthesize a series of analogs of fluoroacetyl-CoA and acetyl-CoA to generate nonhydrolyzable ester, amide, and ketone congeners of the thioester substrate to isolate the role of fluorine molecular recognition in FlK selectivity. Using a combination of thermodynamic, kinetic, and protein NMR experiments, we show that fluorine recognition is entropically driven by the interaction of the fluorine substituent with a key residue, Phe-36, on the lid structure that covers the active site, resulting in an ~5- to 20-fold difference in binding (KD). Although the magnitude of discrimination is similar to that found in designed synthetic ligand-protein complexes where dipolar interactions control fluorine recognition, these studies show that hydrophobic and solvation effects serve as the major determinant of naturally evolved fluorine selectivity. PMID- 29453277 TI - Editing out five Serpina1 paralogs to create a mouse model of genetic emphysema. AB - Chronic obstructive pulmonary disease affects 10% of the worldwide population, and the leading genetic cause is alpha-1 antitrypsin (AAT) deficiency. Due to the complexity of the murine locus, which includes up to six Serpina1 paralogs, no genetic animal model of the disease has been successfully generated until now. Here we create a quintuple Serpina1a-e knockout using CRISPR/Cas9-mediated genome editing. The phenotype recapitulates the human disease phenotype, i.e., absence of hepatic and circulating AAT translates functionally to a reduced capacity to inhibit neutrophil elastase. With age, Serpina1 null mice develop emphysema spontaneously, which can be induced in younger mice by a lipopolysaccharide challenge. This mouse models not only AAT deficiency but also emphysema and is a relevant genetic model and not one based on developmental impairment of alveolarization or elastase administration. We anticipate that this unique model will be highly relevant not only to the preclinical development of therapeutics for AAT deficiency, but also to emphysema and smoking research. PMID- 29453278 TI - Molecular signatures of circulating melanoma cells for monitoring early response to immune checkpoint therapy. AB - A subset of patients with metastatic melanoma have sustained remissions following treatment with immune checkpoint inhibitors. However, analyses of pretreatment tumor biopsies for markers predictive of response, including PD-1 ligand (PD-L1) expression and mutational burden, are insufficiently precise to guide treatment selection, and clinical radiographic evidence of response on therapy may be delayed, leading to some patients receiving potentially ineffective but toxic therapy. Here, we developed a molecular signature of melanoma circulating tumor cells (CTCs) to quantify early tumor response using blood-based monitoring. A quantitative 19-gene digital RNA signature (CTC score) applied to microfluidically enriched CTCs robustly distinguishes melanoma cells, within a background of blood cells in reconstituted and in patient-derived (n = 42) blood specimens. In a prospective cohort of 49 patients treated with immune checkpoint inhibitors, a decrease in CTC score within 7 weeks of therapy correlates with marked improvement in progression-free survival [hazard ratio (HR), 0.17; P = 0.008] and overall survival (HR, 0.12; P = 0.04). Thus, digital quantitation of melanoma CTC-derived transcripts enables serial noninvasive monitoring of tumor burden, supporting the rational application of immune checkpoint inhibition therapies. PMID- 29453280 TI - Elevated Expression of IL-33 and TSLP in the Airways of Human Asthmatics In Vivo: A Potential Biomarker of Severe Refractory Disease. AB - The epithelial cytokines IL-33, thymic stromal lymphopoietin (TSLP), and IL-25 have been implicated in asthma pathogenesis because they promote Th2-type cytokine synthesis, but their expression is relatively poorly documented in "real life" human asthma. Using bronchoalveolar lavage fluid (BALF), we measured airway concentrations of these mediators and compared them with those of Th1- and Th2 type cytokines, airway infiltration of neutrophils and eosinophils, and lung function in a large group of asthmatic patients with a range of disease severity (n = 70) and control subjects (n = 30). The median BALF concentrations of IL-33, TSLP, IL-4, IL-5, IL-13, and IL-12p70, but not IL-25, IL-2, or IFN-gamma, were significantly elevated in asthmatics compared with controls (p < 0.05). The concentrations of IL-33 and TSLP, but not IL-25, correlated inversely with the lung function (forced expiratory volume in the first second) of asthmatics (IL 33: r = -0.488, p < 0.0001; TSLP: r = -0.565, p < 0.0001) independently of corticosteroid therapy. When divided according to disease severity and corticosteroid therapy, all subgroups of asthmatics had elevated median numbers of eosinophils in BALF, whereas the patients with more severe disease who were treated with corticosteroids had higher numbers of neutrophils compared with milder asthmatics not so treated and control subjects (p < 0.05). The data implicate TSLP and IL-33 in the pathogenesis of asthma that is characterized by persistent airway inflammation and impaired lung function despite intensive corticosteroid therapy, highlighting them as potential molecular targets. PMID- 29453279 TI - IL-12+IL-18 Cosignaling in Human Macrophages and Lung Epithelial Cells Activates Cathelicidin and Autophagy, Inhibiting Intracellular Mycobacterial Growth. AB - The ability of Mycobacterium tuberculosis to block host antimicrobial responses in infected cells provides a key mechanism for disease pathogenesis. The immune system has evolved to overcome this blockade to restrict the infection, but it is not clear whether two key innate cytokines (IL-12/IL-18) involved in host defense can enhance antimycobacterial mechanisms. In this study, we demonstrated that the combination of IL-12 and IL-18 triggered an antimicrobial response against mycobacteria in infected macrophages (THP-1 and human primary monocyte-derived macrophages) and pulmonary epithelial A549 cells. The inhibition of intracellular bacterial growth required p38-MAPK and STAT4 pathways, the vitamin D receptor, the vitamin D receptor-derived antimicrobial peptide cathelicidin, and autophagy, but not caspase-mediated apoptosis. Finally, the ability of IL-12+IL-18 to activate an innate antimicrobial response in human primary macrophages was dependent on the autonomous production of IFN-gamma and the CAMP/autophagy pathway. Together, these data suggest that IL-12+IL-18 cosignaling can trigger the antimicrobial protein cathelicidin and autophagy, resulting in inhibition of intracellular mycobacteria in macrophages and lung epithelial cells. PMID- 29453281 TI - The PI3Kdelta-Selective Inhibitor Idelalisib Minimally Interferes with Immune Effector Function Mediated by Rituximab or Obinutuzumab and Significantly Augments B Cell Depletion In Vivo. AB - Idelalisib is a highly selective oral inhibitor of PI3Kdelta indicated for the treatment of patients with relapsed chronic lymphocytic leukemia in combination with rituximab. Despite additive clinical effects, previous studies have paradoxically demonstrated that targeted therapies potentially negatively affect anti-CD20 mAb effector mechanisms. To address these potential effects, we investigated the impact of PI3Kdelta inhibition by idelalisib on the effector mechanisms of rituximab and obinutuzumab. At clinically relevant concentrations, idelalisib minimally influenced rituximab- and obinutuzumab-mediated Ab-dependent cellular cytotoxicity and phagocytosis on human lymphoma cell lines, while maintaining the superiority of obinutuzumab-mediated Ab-dependent cellular cytotoxicity. Consistent with this, idelalisib did not influence obinutuzumab mediated B cell depletion in whole-blood B cell-depletion assays. Further, idelalisib significantly enhanced obinutuzumab-mediated direct cell death of chronic lymphocytic leukemia cells. In murine systems, in vivo inhibition of PI3Kdelta minimally interfered with maximal rituximab- or obinutuzumab-mediated depletion of leukemic targets. In addition, the duration of rituximab- and obinutuzumab-mediated depletion of leukemia cells was extended by combination with PI3Kdelta inhibition. Collectively, these data demonstrate that PI3Kdelta inhibition does not significantly affect the effector mechanisms induced by rituximab or obinutuzumab and provides an effective in vivo therapeutic combination. Therefore, combinations of obinutuzumab and idelalisib are currently being assessed in clinical studies. PMID- 29453282 TI - Eukaryotic translation elongation factor 2 (eEF2) catalyzes reverse translocation of the eukaryotic ribosome. AB - During protein synthesis, a ribosome moves along the mRNA template and, using aminoacyl-tRNAs, decodes the template nucleotide triplets to assemble a protein amino acid sequence. This movement is accompanied by shifting of mRNA-tRNA complexes within the ribosome in a process called translocation. In living cells, this process proceeds in a unidirectional manner, bringing the ribosome to the 3' end of mRNA, and is catalyzed by the GTPase translation elongation factor 2 (EF-G in prokaryotes and eEF2 in eukaryotes). Interestingly, the possibility of spontaneous backward translocation has been shown in vitro for bacterial ribosomes, suggesting a potential reversibility of this reaction. However, this possibility has not yet been tested for eukaryotic ribosomes. Here, using a reconstituted mammalian translation system, we show that the eukaryotic elongation factor eEF2 catalyzes ribosomal reverse translocation at one mRNA triplet. We found that this process requires a cognate tRNA in the ribosomal E site and cannot occur spontaneously without eEF2. The efficiency of this reaction depended on the concentrations of eEF2 and cognate tRNAs and increased in the presence of nonhydrolyzable GTP analogues. Of note, ADP-ribosylation of eEF2 domain IV blocked reverse translocation, suggesting a crucial role of interactions of this domain with the ribosome for the catalysis of the reaction. In summary, our findings indicate that eEF2 is able to induce ribosomal translocation in forward and backward directions, highlighting the universal mechanism of tRNA-mRNA movements within the ribosome. PMID- 29453283 TI - Chemical stresses fail to mimic the unfolded protein response resulting from luminal load with unfolded polypeptides. AB - The stress sensors ATF6, IRE1, and PERK monitor deviations from homeostatic conditions in the endoplasmic reticulum (ER), a protein biogenesis compartment of eukaryotic cells. Their activation elicits unfolded protein responses (UPR) to re establish proteostasis. UPR have been extensively investigated in cells exposed to chemicals that activate ER stress sensors by perturbing calcium, N-glycans, or redox homeostasis. Cell responses to variations in luminal load with unfolded proteins are, in contrast, poorly characterized. Here, we compared gene and protein expression profiles in HEK293 cells challenged with ER stress-inducing drugs or expressing model polypeptides. Drug titration to limit up-regulation of the endogenous ER stress reporters heat shock protein family A (Hsp70) member 5 (BiP/HSPA5) and homocysteine-inducible ER protein with ubiquitin-like domain 1 (HERP/HERPUD1) to levels comparable with luminal accumulation of unfolded proteins substantially reduced the amplitude of both transcriptional and translational responses. However, these drug-induced changes remained pleiotropic and failed to recapitulate responses to ER load with unfolded proteins. These required unfolded protein association with BiP and induced a much smaller subset of genes participating in a chaperone complex that binds unfolded peptide chains. In conclusion, UPR resulting from ER load with unfolded proteins proceed via a well-defined and fine-tuned pathway, whereas even mild chemical stresses caused by compounds often used to stimulate UPR induce cellular responses largely unrelated to the UPR or ER-mediated protein secretion. PMID- 29453284 TI - Structural and compositional diversity of fibrillin microfibrils in human tissues. AB - Elastic fibers comprising fibrillin microfibrils and elastin are present in many tissues, including the skin, lungs, and arteries, where they confer elasticity and resilience. Although fibrillin microfibrils play distinct and tissue-specific functional roles, it is unclear whether their ultrastructure and composition differ between elastin-rich (skin) and elastin-poor (ciliary body and zonule) organs or after in vitro synthesis by cultured cells. Here, we used atomic force microscopy, which revealed that the bead morphology of fibrillin microfibrils isolated from the human eye differs from those isolated from the skin. Using newly developed pre-MS preparation methods and LC-MS/MS, we detected tissue specific regions of the fibrillin-1 primary structure that were differentially susceptible to proteolytic extraction. Comparing tissue- and culture-derived microfibrils, we found that dermis- and dermal fibroblast-derived fibrillin microfibrils differ in both bead morphology and periodicity and also exhibit regional differences in fibrillin-1 proteolytic susceptibility. In contrast, collagen VI microfibrils from the same dermal or fibroblast samples were invariant in ultrastructure (periodicity) and protease susceptibility. Finally, we observed that skin- and eye-derived microfibril suspensions were enriched in elastic fiber- and basement membrane-associated proteins, respectively. LC-MS/MS also identified proteins (such as calreticulin and protein-disulfide isomerase) that are potentially fundamental to fibrillin microfibril biology, regardless of their tissue source. Fibrillin microfibrils synthesized in cell culture lacked some of these key proteins (MFAP2 and -4 and fibrillin-2). These results showcase the structural diversity of these key extracellular matrix assemblies, which may relate to their distinct roles in the tissues where they reside. PMID- 29453285 TI - The distal upstream region of insulin-like growth factor-binding protein-1 enhances its expression in endometrial stromal cells during decidualization. AB - We have previously shown that decidualization of human endometrial stromal cells (ESCs) causes a genome-wide increase in the levels of acetylation of histone-H3 Lys-27 (H3K27ac). We also reported that the distal gene regions, more than 3 kb up- or downstream of gene transcription start sites have increased H3K27ac levels. Insulin-like growth factor-binding protein-1 (IGFBP-1) is a specific decidualization marker and has increased H3K27ac levels in its distal upstream region (-4701 to -7501 bp). Here, using a luciferase reporter gene construct containing this IGFBP-1 upstream region, we tested the hypothesis that it is an IGFBP-1 enhancer. To induce decidualization, we incubated ESCs with cAMP and found that cAMP increased luciferase expression, indicating that decidualization increased the transcriptional activity from the IGFBP-1 upstream region. Furthermore, CRISPR/Cas9-mediated deletion of this region in HepG2 cells significantly reduced IGFBP-1 expression, confirming its role as an IGFBP-1 enhancer. A ChIP assay revealed that cAMP increased the recruitment of the transcriptional regulators CCAAT enhancer-binding protein beta (C/EBPbeta), forkhead box O1 (FOXO1), and p300 to the IGFBP-1 enhancer in ESCs. Of note, C/EBPbeta knockdown inhibited the stimulatory effects of cAMP on the levels of H3K27ac, chromatin opening, and p300 recruitment at the IGFBP-1 enhancer. These results indicate that the region -4701 to -7501 bp upstream of IGFBP-1 functions as an enhancer for IGFBP-1 expression in ESCs undergoing decidualization, that C/EBPbeta and FOXO1 bind to the enhancer region to up-regulate IGFBP-1 expression, and that C/EBPbeta induces H3K27ac by recruiting p300 to the IGFBP-1 enhancer.

AB - Both Hsp70 and Hsp90 chaperones are overexpressed in cancer, making them relevant targets for the development of cancer chemotherapeutics, but a lack of biomolecular readouts for Hsp70 inhibition has limited the pursuit of specific inhibitors for this enzyme. A new study from Cesa et al. identifies two inhibitors of apoptosis proteins (IAPs) as specific client substrates of Hsp70. These results establish biomarkers that can be utilized to monitor Hsp70 inhibition and provide a framework for future efforts to deconvolute chaperone networks. PMID- 29453287 TI - Adoption of Sacubitril/Valsartan for the Management of Patients With Heart Failure. AB - BACKGROUND: The US Food and Drug Administration approved the use of sacubitril/valsartan in patients with heart failure with reduced ejection fraction in July 2015. We aimed to assess the adoption and prescription drug costs of sacubitril/valsartan in its first 18 months after Food and Drug Administration approval. METHODS AND RESULTS: Using a large US insurance database, we identified privately insured and Medicare Advantage beneficiaries who filled a first prescription for sacubitril/valsartan between July 1, 2015, and December 31, 2016. We compared them to patients treated with an angiotensin converting enzyme inhibitor or angiotensin receptor blocker. Outcomes included adoption, prescription drug costs, and 180-day adherence, defined as a proportion of days covered >=80%. A total of 2244 patients initiated sacubitril/valsartan. Although the number of users increased over time, the proportion of heart failure with reduced ejection fraction patients taking sacubitril/valsartan remained low (<3%). Patients prescribed sacubitril/valsartan were younger, more often male, with less comorbidity than those taking an angiotensin-converting enzyme inhibitor/angiotensin receptor blocker. Although a majority of prescription costs were covered by the health plan (mean, $328.37; median, $362.44 per 30-day prescription), out-of-pocket costs were still high (mean, $71.16; median, $40.27). By comparison, median out-of-pocket costs were $2 to $3 for lisinopril, losartan, carvedilol, and spironolactone. Overall, 59.1% of patients were adherent to sacubitril/valsartan. Refill patterns suggested that nearly half of nonadherent patients discontinued sacubitril/valsartan within 180 days of starting. CONCLUSIONS: Adoption of sacubitril/valsartan after Food and Drug Administration approval has been slow and may be associated with the high cost.

PMID- 29453290 TI - Mouse and human HSPC immobilization in liquid culture by CD43- or CD44-antibody coating. AB - Keeping track of individual cell identifications is imperative to the study of dynamic single-cell behavior over time. Highly motile hematopoietic stem and progenitor cells (HSPCs) migrate quickly and do not adhere, and thus must be imaged very frequently to keep cell identifications. Even worse, they are also flushed away during medium exchange. To overcome these limitations, we tested antibody coating for reducing HSPC motility in vitro. Anti-CD43- and anti-CD44 antibody coating reduced the cell motility of mouse and human HSPCs in a concentration-dependent manner. This enables 2-dimensional (2D) colony formation without cell mixing in liquid cultures, massively increases time-lapse imaging throughput, and also maintains cell positions during media exchange. Anti-CD43 but not anti-CD44 coating reduces mouse HSPC proliferation with increasing concentrations. No relevant effects on cell survival or myeloid and megakaryocyte differentiation of hematopoietic stem cells and multipotent progenitors 1-5 were detected. Human umbilical cord hematopoietic CD34+ cell survival, proliferation, and differentiation were not affected by either coating. This approach both massively simplifies and accelerates continuous analysis of suspension cells, and enables the study of their behavior in dynamic rather than static culture conditions over time. PMID- 29453291 TI - LSD1 inhibition exerts its antileukemic effect by recommissioning PU.1- and C/EBPalpha-dependent enhancers in AML. AB - Epigenetic regulators are recurrently mutated and aberrantly expressed in acute myeloid leukemia (AML). Targeted therapies designed to inhibit these chromatin modifying enzymes, such as the histone demethylase lysine-specific demethylase 1 (LSD1) and the histone methyltransferase DOT1L, have been developed as novel treatment modalities for these often refractory diseases. A common feature of many of these targeted agents is their ability to induce myeloid differentiation, suggesting that multiple paths toward a myeloid gene expression program can be engaged to relieve the differentiation blockade that is uniformly seen in AML. We performed a comparative assessment of chromatin dynamics during the treatment of mixed lineage leukemia (MLL)-AF9-driven murine leukemias and MLL-rearranged patient-derived xenografts using 2 distinct but effective differentiation inducing targeted epigenetic therapies, the LSD1 inhibitor GSK-LSD1 and the DOT1L inhibitor EPZ4777. Intriguingly, GSK-LSD1 treatment caused global gains in chromatin accessibility, whereas treatment with EPZ4777 caused global losses in accessibility. We captured PU.1 and C/EBPalpha motif signatures at LSD1 inhibitor induced dynamic sites and chromatin immunoprecipitation coupled with high throughput sequencing revealed co-occupancy of these myeloid transcription factors at these sites. Functionally, we confirmed that diminished expression of PU.1 or genetic deletion of C/EBPalpha in MLL-AF9 cells generates resistance of these leukemias to LSD1 inhibition. These findings reveal that pharmacologic inhibition of LSD1 represents a unique path to overcome the differentiation block in AML for therapeutic benefit. PMID- 29453292 TI - Clonal selection drives protective memory B cell responses in controlled human malaria infection. AB - Affinity maturation, the clonal selection and expansion of antigen-activated B cells expressing somatically mutated antibody variants that develop during T cell dependent germinal center reactions, is considered pivotal for efficient development of protective B cell memory responses to infection and vaccination. Repeated antigen exposure promotes affinity maturation but each time also recruits antigen-reactive naive B cells into the response. Here, we determined the relative impact of affinity maturation versus antigen-mediated clonal selection of naive B cells to mount potent B cell memory responses in humans after repeated exposure to a complex pathogen, the malaria parasite Plasmodium falciparum (Pf). Using single-cell immunoglobulin (Ig) gene sequencing and production of recombinant monoclonal antibodies, we analyzed the origin, development, and quality of memory B cell responses to Pf circumsporozoite protein (PfCSP), the major sporozoite surface protein. We show that after repeated immunization of Pf-naive volunteers with infectious Pf sporozoites (PfSPZ Challenge) under chloroquine prophylaxis (PfSPZ-CVac), the clonal selection of potent germline and memory B cell precursors against the central PfCSP NANP repeat outpaces affinity maturation because the majority of Ig gene mutations are affinity-neutral. Mathematical modeling explains how the efficiency of affinity maturation decreases strongly with antigen complexity. Thus, in the absence of long-term exposure, the frequency of antigen-reactive precursors and likelihood of their activation rather than affinity maturation will determine the quality of anti-PfCSP memory B cell responses. These findings have wide implications for the design of vaccination strategies to induce potent B cell memory responses against PfCSP and presumably other structurally complex antigens. PMID- 29453294 TI - Public preferences for interventions to prevent emerging infectious disease threats: a discrete choice experiment. AB - OBJECTIVE: When faced with an emergent epidemic with high mortality and morbidity potential, policy makers must decide what public health interventions to deploy at different stages of the outbreak. However, almost nothing is known about how the public view these interventions or how they trade off risks (of disease) with inconvenience (of interventions). In this paper, we aim to understand public perceptions on pandemic interventions, as well as to identify if there are any distinct respondent preference classes. DESIGN: A discrete choice experiment. SETTING: This study was fielded in Singapore between November 2012 and February 2013. PARTICIPANTS: A random sample of 500 Singapore residents aged 21 and over, including 271 women and 229 men, was analysed. OUTCOME MEASURES: Demographic information was collected from each participant. Participants were also shown a series of pairs of alternatives, each combining interventions and morbidity, mortality and cost outcomes and declared a preference for one combination. A random utility model was developed to determine the individual's preference for interventions and a hierarchical cluster analysis was performed to identify distinct respondent preference classes. RESULTS: On average, participants preferred more intense interventions, and preferred scenarios with fewer deaths and lower tax. The number of infections did not significantly influence respondents' responses. We identified two broad classes of respondents: those who were mortality averse and those who were expenditure averse. Education was found to be a predictor of group membership. CONCLUSION: Overall, there was considerable support for government interventions to prevent or mitigate outbreaks of emerging infectious diseases, including those that greatly restricted individual liberties, as long as the restrictions showed a reasonable chance of reducing the adverse health effects of the outbreak. PMID- 29453293 TI - Protein phosphorylation maintains the normal function of cloned human Cav2.3 channels. AB - R-type currents mediated by native and recombinant Cav2.3 voltage-gated Ca2+ channels (VGCCs) exhibit facilitation (run-up) and subsequent decline (run-down) in whole-cell patch-clamp recordings. A better understanding of the two processes could provide insight into constitutive modulation of the channels in intact cells, but low expression levels and the need for pharmacological isolation have prevented investigations in native systems. Here, to circumvent these limitations, we use conventional and perforated-patch-clamp recordings in a recombinant expression system, which allows us to study the effects of cell dialysis in a reproducible manner. We show that the decline of currents carried by human Cav2.3+beta3 channel subunits during run-down is related to adenosine triphosphate (ATP) depletion, which reduces the number of functional channels and leads to a progressive shift of voltage-dependent gating to more negative potentials. Both effects can be counteracted by hydrolysable ATP, whose protective action is almost completely prevented by inhibition of serine/threonine but not tyrosine or lipid kinases. Protein kinase inhibition also mimics the effects of run-down in intact cells, reduces the peak current density, and hyperpolarizes the voltage dependence of gating. Together, our findings indicate that ATP promotes phosphorylation of either the channel or an associated protein, whereas dephosphorylation during cell dialysis results in run down. These data also distinguish the effects of ATP on Cav2.3 channels from those on other VGCCs because neither direct nucleotide binding nor PIP2 synthesis is required for protection from run-down. We conclude that protein phosphorylation is required for Cav2.3 channel function and could directly influence the normal features of current carried by these channels. Curiously, some of our findings also point to a role for leupeptin-sensitive proteases in run-up and possibly ATP protection from run-down. As such, the present study provides a reliable baseline for further studies on Cav2.3 channel regulation by protein kinases, phosphatases, and possibly proteases. PMID- 29453295 TI - Socioeconomic, religious, spiritual and health factors associated with symptoms of common mental disorders: a cross-sectional secondary analysis of data from Bhutan's Gross National Happiness Study, 2015. AB - OBJECTIVE: Common mental disorders (CMDs) are a major cause of the global burden of disease. Bhutan was the first country in the world to focus on happiness as a state policy; however, little is known about the prevalence and risk factors of CMDs in this setting. We aim to identify socioeconomic, religious, spiritual and health factors associated with symptoms of CMDs. DESIGN AND SETTING: We used data from Bhutan's 2015 Gross National Happiness (GNH) Survey, a multistage, cross sectional nationwide household survey. Data were analysed using a hierarchical analytical framework and generalised estimating equations. PARTICIPANTS: The GNH Survey included 7041 male and female respondents aged 15 years and above. MEASURES: The 12-item General Health Questionnaire was used to measure symptoms of CMDs. We estimated the prevalence of CMDs using a threshold score of >=12. RESULTS: The prevalence of CMDs was 29.3% (95% CI 26.8% to 31.8%). Factors associated with symptoms of CMDs were: older age (65+) (beta=1.29, 95% CI 0.57 to 2.00), being female (beta=0.70, 95% CI 0.45 to 0.95), being divorced or widowed (beta=1.55, 95% CI 1.08 to 2.02), illiteracy (beta=0.48, 95% CI 0.21 to 0.74), low income (beta=0.37, 95% CI 0.15 to 0.59), being moderately spiritual (beta=0.61, 95% CI 0.34 to 0.88) or somewhat or not spiritual (beta=0.76, 95% CI 0.28 to 1.23), occasionally considering karma in daily life (beta=0.53, 95% CI 0.29 to 0.77) or never considering karma (beta=0.80, 95% CI 0.26 to 1.34), having poor self-reported health (beta=2.59, 95% CI 2.13 to 3.06) and having a disability (beta=1.01, 95% CI 0.63 to 1.40). CONCLUSIONS: CMDs affect a substantial proportion of the Bhutanese population. Our findings confirm the importance of established socioeconomic risk factors for CMDs, and suggest a potential link between spiritualism and mental health in this setting. PMID- 29453296 TI - Understanding the characteristics of recurrent visits to the emergency department by paediatric patients: a retrospective observational study conducted at three tertiary hospitals in Korea. AB - OBJECTIVES: The number of paediatric patients visiting the emergency department (ED) continues to rise. In South Korea, approximately 25% of the patients who visit the ED are paediatric patients. In the USA, about 20% of the paediatric population were found to have visited the ED in the past year. A recent study demonstrated that 4.5%-8% of patients account for 25% of all ED visits. Therefore, the aim of this study was to identify the characteristics of recurrent visits. METHODS: Design: retrospective observational study. SETTING: this study examined and analysed medical record data involving three tertiary EDs. PARTICIPANTS: a total of 46 237 ED visits by patients <16 years during 1-year period. MAIN OUTCOME MEASURES: data collected included the number of recurrent ED patients, frequency of recurrent visits, age, sex, insurance status, period until recurrent visit (days), main diagnosis and ED discharge results. RESULTS: Excluding patients with multiple visits, the total number of paediatric patients who fit the study criteria was 33 765. Among these patients, 23 384 (69.2%) had no recurrent ED visits in the subsequent year after their first visit. A total of 15 849 (46.8%) patients were toddlers (between age 1 and 4 years). In the patient group without a recurrent visit, fever was the most common diagnosis. CONCLUSIONS: Our study reviewed medical records to inspect the characteristics of patients who return to care. Higher recurrent visit frequency was associated with using the 119 rescue centre service, having a medical condition, with younger age and a higher rate of hospitalisation. Analysis of the factors associated with frequent ED visits will help to improve care for paediatric patients who visit the ED. PMID- 29453297 TI - What factors mediate the inter-relationship between frailty and pain in cognitively and functionally sound older adults? A prospective longitudinal ageing cohort study in Taiwan. AB - OBJECTIVES: The main aim was to investigate the complex inter-relationship between frailty and pain, and the mediating roles of cognitive function, morbidity and mood in this nexus. DESIGN: A cross-sectional analysis. SETTING: A prospective community-dwelling population-based cohort. PARTICIPANTS: 1682 adults age >=50 years without evident cognitive or functional impairment, or history of cancer. PRIMARY AND SECONDARY OUTCOME MEASURES: The mediating effect of depression, cognitive function and comorbidity on the nexus between pain and frailty among older and middle-aged adults. RESULTS: The pain score among older subjects (>=65 years), increased with the degree of frailty (robust=0.96+/-0.82; pre-frail=1.13+/-0.86; frail=1.63+/-1.02; P<0.001); multivariate analysis gave the same result, while moderate pain was associated with frailty in older subjects (OR=3.00, 95% CI 1.30 to 6.60). Conversely, pain and frailty among middle-aged subjects (aged 50-64 years) did not appear to be significantly related; in mediation analysis, pain exerted an indirect effect on frailty via depression (indirect effect=0.03, 95% CI 0.01 to 0.07), while neither cognitive function nor comorbidity had any significant effect in mediating the relationship between pain and frailty. CONCLUSION: In cognitively and functionally sound community-dwelling adults aged >=50 years, moderate pain was related to frailty in those older than 65 years, but not younger ones. Besides the direct influence of pain on frailty, depression partially mediated the pain-frailty nexus. The mechanism by which depression influences pain and frailty requires further investigation. PMID- 29453298 TI - Urban green spaces and cancer: a protocol for a scoping review. AB - INTRODUCTION: Green space in the built environment is an important topic on the health agenda today. Studies have shown that access to green spaces is associated with better mental and physical health, yet green spaces can also be detrimental to health if they are not managed appropriately. Despite the increasing interest in urban green spaces, little research has so far been conducted into the links between green spaces and cancer. OBJECTIVE: The purpose of this scoping review is therefore to map the literature available on the types of relationship between urban green spaces and cancer. METHOD AND ANALYSIS: We followed the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols 2015 guideline to report the protocol. To conduct this scoping review, we will use a structured search strategy based on controlled vocabulary and relevant key terms related to green space, urban space and cancer. We will search MEDLINE (PubMed), GreenFILE (EBSCOhost), Cumulative Index to Nursing and Allied Health Literature (EBSCOhost) and ScienceDirect as electronic database as well as hand-search publications for grey literature. This review will therefore provide evidence on this current topic, one which could have practical implications for policy-makers involved in choices which are more conducive to healthy living. ETHICS AND DISSEMINATION: No primary data will be collected since all data that will be presented in this review are based on published articles and publicly available documents, and therefore ethics committee approval is not a requirement. The findings of this review will be presented at workshops and conferences, and will be submitted for publication in a peer-reviewed journal. PMID- 29453299 TI - Pulmonary sarcoidosis with and without extrapulmonary involvement: a cross sectional and observational study in China. AB - OBJECTIVES: Sarcoidosis is a multisystem disease characterised by the formation of granulomas within various organs, mainly the lungs. Several studies from different countries have been undertaken to investigate sarcoidosis with extrapulmonary involvement except from China. The objective of this study is to investigate a comparative clinical analysis in patients with pulmonary sarcoidosis with and without extrapulmonary involvement from China. METHODS: Data from inpatients diagnosed with sarcoidosis at Shanghai Pulmonary Hospital (Shanghai, China) between January 2009 and December 2014 were retrospectively collected and analysed. Six hundred and thirty-six patients with biopsy-proven sarcoidosis were included in the study, including 378 isolated pulmonary sarcoidosis and 258 pulmonary sarcoidosis plus extrapulmonary involvement. RESULTS: Two hundred and fifty-eight (40.6%) patients with pulmonary sarcoidosis had extrapulmonary involvement. Extrapulmonary localisations were detected mostly in extrathoracic lymph nodes (n=147) and skin (n=86). Statistically significant differences were demonstrated between patients with pulmonary sarcoidosis plus extrapulmonary involvement and patients with isolated pulmonary sarcoidosis for fatigue (16.6%vs8.3%, P<0.05), serum ACE (SACE) levels (79.0+/-46.9 IU/L vs 69.7+/-38.7 IU/L, P<0.05), and high-resolution CT (HRCT) findings (53.8%vs46.2%, P<0.05). CONCLUSIONS: Extrapulmonary involvement is common in patients with pulmonary sarcoidosis, with the most common sites being extrathoracic lymph nodes and skin. Patients with sarcoidosis with extrapulmonary involvement are more symptomatic (fatigue), have higher SACE levels and more deteriorating HRCT findings, to which clinicians should pay attention. PMID- 29453300 TI - School-based lifestyle education involving parents for reducing subjective psychosomatic symptoms in Japanese adolescents: study protocol for a cluster randomised controlled trial. AB - INTRODUCTION: Severe subjective psychosomatic symptoms (SPS) in adolescents are a major public health concern, and lifestyle modification interventions for reducing SPS are important topics. Recently, we developed a school-based lifestyle education involving parents for reducing SPS of adolescents (SPRAT), an improved version of the programme from our previous study Programme for adolescent of lifestyle education in Kumamoto (PADOK). This study aimed to evaluate the effectiveness of SPRAT in reducing SPS among adolescents. METHODS AND ANALYSIS: This is a 6-month, cluster randomised clinical trial with two intervention arms (SPRAT vs usual school education). The study population will be composed of middle school students (aged 12-14 years) with their parents/guardians in Japan. SPRAT is expected to be a more powerful programme than PADOK as it reinforces the role of parent participation. The primary endpoint will be the change from baseline SPS scores to those obtained after 6 months. Between-group differences will be analysed following the intention-to treat principle. Crude and multivariate adjusted effects will be examined using a general linear mixed-effects model for continuous variables and a logistic regression model for dichotomous variables. The sample size required was determined based on the information needed to detect a difference in the primary outcome with a significance level of 5% and power of 80% under the assumptions of 40 students per cluster (assuming the same sample size for each cluster), an effect size of 0.3 and an intraclass correlation coefficient of 0.02. In total, participation by 28 schools (14 schools in each arm) (students: n=1120) will be needed. ETHICS AND DISSEMINATION: This study was approved by the Medical Ethical Committee of Minami Kyushu University in 2017 (number 137). The findings will be disseminated widely through peer-reviewed publications and conference presentations. TRIAL REGISTRATION NUMBER: UMIN000026715; Pre-results. PMID- 29453302 TI - Characteristics and publication fate of unregistered and retrospectively registered clinical trials submitted to The BMJ over 4 years. AB - OBJECTIVES: We sought to evaluate the characteristics and publication fate of improperly registered clinical trials submitted to a medical journal (The BMJ) over a 4-year period to identify common types of registration issues and their relation to publication outcomes. DESIGN: Research articles submitted to The BMJ and identified as unregistered or retrospectively registered by editors were included if they reported outcomes of a clinical trial. Relevant data regarding the trials were then extracted from each paper. Trials were categorised as prospectively registered, registered in an unapproved registry, unregistered or other, and explanations for registration deficiencies were grouped into six categories. We searched PubMed and Google to determine whether, where and when improperly registered studies were subsequently published and whether registration issues were disclosed. RESULTS: 123 research papers reporting apparently unregistered or retrospectively registered clinical trials were identified. 110 studies (89.4%) were retrospectively registered, nine (7.3%) were unregistered, three (2.4%) had been registered in an unapproved registry and one study originally lacking registration details was later discovered to have been prospectively registered. 82 studies (66.6%) were funded entirely or in part by government sources, and only seven studies (5.7%) received funding from industry. Of those papers submitted to The BMJ through the end of 2015, 67 of the 70 papers rejected for registration problems (95.7%) were subsequently published in another journal. The registration problem was disclosed in only 2 (2.9%). CONCLUSIONS: Improper registration remains a problem, particularly for clinical trials that are government or foundation-funded. Nonetheless, improperly registered trials are almost always published, suggesting that medical journal editors may not actively enforce registration requirements. PMID- 29453303 TI - Identifying positively deviant elderly medical wards using routinely collected NHS Safety Thermometer data: an observational study. AB - OBJECTIVE: The positive deviance approach seeks to identify and learn from exceptional performers. Although a framework exists to apply positive deviance within healthcare organisations, there is limited guidance to support its implementation. The approach has also rarely explored exceptional performance on broad outcomes, been implemented at ward level, or applied within the UK. This study develops and critically appraises a pragmatic method for identifying positively deviant wards using a routinely collected, broad measure of patient safety. DESIGN: A two-phased observational study was conducted. During phase 1, cross-sectional and temporal analyses of Safety Thermometer data were conducted to identify a discrete group of positively deviant wards that consistently demonstrated exceptional levels of safety. A group of matched comparison wards with above average performances were also identified. During phase 2, multidisciplinary staff and patients on the positively deviant and comparison wards completed surveys to explore whether their perceptions of safety supported the identification of positively deviant wards. SETTING: 34 elderly medical wards within a northern region of England, UK. PARTICIPANTS: Multidisciplinary staff (n=161) and patients (n=188) clustered within nine positively deviant and comparison wards. RESULTS: Phase 1: A combination of analyses identified five positively deviant wards that performed best in the region, outperformed their organisation and performed consistently well over 12 months. Five above average matched comparator wards were also identified. Phase 2: Staff and patient perceptions of safety generally supported the identification of positively deviant wards using Safety Thermometer data, although patient perceptions of safety were less concordant with the routinely collected data. CONCLUSIONS: This study tentatively supports a pragmatic method of using routinely collected data to identify positively deviant elderly medical wards; however, it also highlights the various challenges that are faced when conducting the first stage of the positive deviance approach. TRIAL REGISTRATION NUMBER: UK Clinical Research Network Portfolio (reference-18050). PMID- 29453301 TI - Role of the family doctor in the management of adults with obesity: a scoping review. AB - OBJECTIVES: Obesity management is an important issue for the international primary care community. This scoping review examines the literature describing the role of the family doctor in managing adults with obesity. The methods were prospectively published and followed Joanna Briggs Institute methodology. SETTING: Primary care. Adult patients. INCLUDED PAPERS: Peer-reviewed and grey literature with the keywords obesity, primary care and family doctors. All literature published up to September 2015. 3294 non-duplicate papers were identified and 225 articles included after full-text review. PRIMARY AND SECONDARY OUTCOME MEASURES: Data were extracted on the family doctors' involvement in different aspects of management, and whether whole person and person-centred care were explicitly mentioned. RESULTS: 110 papers described interventions in primary care and family doctors were always involved in diagnosing obesity and often in recruitment of participants. A clear description of the provider involved in an intervention was often lacking. It was difficult to determine if interventions took account of whole person and person centredness. Most opinion papers and clinical overviews described an extensive role for the family doctor in management; in contrast, research on current practices depicted obesity as undermanaged by family doctors. International guidelines varied in their description of the role of the family doctor with a more extensive role suggested by guidelines from family medicine organisations. CONCLUSIONS: There is a disconnect between how family doctors are involved in primary care interventions, the message in clinical overviews and opinion papers, and observed current practice of family doctors. The role of family doctors in international guidelines for obesity may reflect the strength of primary care in the originating health system. Reporting of primary care interventions could be improved by enhanced descriptions of the providers involved and explanation of how the pillars of primary care are used in intervention development. PMID- 29453305 TI - Frequency and Outcomes of Reduced Dose Non-Vitamin K Antagonist Anticoagulants: Results From ORBIT-AF II (The Outcomes Registry for Better Informed Treatment of Atrial Fibrillation II). AB - BACKGROUND: Non-vitamin K antagonist oral anticoagulants (NOACs) are indicated for stroke prevention in atrial fibrillation (AF) but require lower doses in certain patients. We sought to describe the frequency, appropriateness (according to Food and Drug Administration labeling), and outcomes of patients prescribed reduced doses of NOACs in community practice. METHODS AND RESULTS: We analyzed data from the ORBIT-AF II (The Outcomes Registry for Better Informed Treatment of Atrial Fibrillation II) registry, a prospective, national, observational registry of AF patients. Among 7925 AF patients receiving NOACs, we assessed patterns of use of reduced NOAC doses and associated cardiovascular and bleeding outcomes at median follow-up of 1 year. Overall, 6636 patients (84%) received a NOAC at standard dose, which was consistent with US Food and Drug Administration labeling in 6376 (96%). Reduced NOAC dose was prescribed to 1289 (16% overall), which was consistent with Food and Drug Administration labeling in only 555 patients (43%). Compared with those whose NOAC dose was appropriately reduced, patients receiving inappropriate dose reductions were younger (median age 79 versus 84, P<0.0001) and had lower ORBIT bleeding risk scores (26% >=4 versus 45%, P<0.0001). Compared with those appropriately receiving standard dosing, patients receiving inappropriately reduced-dose NOACs had higher unadjusted rates of thromboembolic events (2.11 versus 1.35 events per 100 patient years, hazard ratio 1.56, 95% confidence interval 0.92-2.67) and death (6.77 versus 2.60, hazard ratio 2.61, 95% confidence interval 1.86-3.67). After adjustment, outcomes were not significantly different but tended to favor patients dosed appropriately. CONCLUSIONS: The majority of dose reductions of NOACs in AF are inconsistent with US Food and Drug Administration recommendations. There appear to be opportunities to improve current NOAC dosing in community practice. CLINICAL TRIAL REGISTRATION: URL: http://www.clinicaltrials.gov. Unique identifier: NCT01701817. PMID- 29453304 TI - Protocol investigating the clinical utility of an objective measure of attention, impulsivity and activity (QbTest) for optimising medication management in children and young people with ADHD 'QbTest Utility for Optimising Treatment in ADHD' (QUOTA): a feasibility randomised controlled trial. AB - INTRODUCTION: Attention-deficit hyperactivity disorder (ADHD) is characterised by symptoms of inattention, hyperactivity and impulsivity. To improve outcomes, the National Institute for Health and Care Excellence ADHD guidelines recommend regular monitoring of symptoms when children commence medication. However, research suggests that routine monitoring rarely happens, and clinicians often rely on subjective information such as reports from parents and teachers to ascertain improvement. These sources can be unreliable and difficult to obtain. The addition of an objective test of attention and activity (QbTest) may improve the objectivity, reliability and speed of clinical decision-making and so reduce the time to identify the optimal medication dose. This study aims to assess the feasibility and acceptability of a QbTest medication management protocol delivered in routine healthcare services for children with ADHD. METHOD AND ANALYSIS: This multisite feasibility randomised controlled trial (RCT) will recruit 60 young people (aged 6-17 years old), diagnosed with ADHD, and starting stimulant medication who are seen by Child and Adolescent Mental Health Services or Community Paediatric services. Participants will be randomised into one of two arms. In the experimental arm (QbTest protocol), the participant will complete a QbTest at baseline (prior to medication initiation), and two follow-up QbTests on medication (2-4 weeks and 8-10 weeks later).

The study has ethical approval. TRIAL REGISTRATION NUMBER: NCT03368573; Pre-results. PMID- 29453306 TI - Acute Pressor Response to Psychosocial Stress Is Dependent on Endothelium-Derived Endothelin-1. AB - BACKGROUND: Acute psychosocial stress provokes increases in circulating endothelin-1 (ET-1) levels in humans and animal models. However, key questions about the physiological function and cellular source of stress-induced ET-1 remain unanswered. We hypothesized that endothelium-derived ET-1 contributes to the acute pressor response to stress via activation of the endothelin A receptor. METHODS AND RESULTS: Adult male vascular endothelium-specific ET-1 knockout mice and control mice that were homozygous for the floxed allele were exposed to acute psychosocial stress in the form of cage switch stress (CSS), with blood pressure measured by telemetry. An acute pressor response was elicited by CSS in both genotypes; however, this response was significantly blunted in vascular endothelium-specific ET-1 knockout mice compared with control mice that were homozygous for the floxed allele. In mice pretreated for 3 days with the endothelin A antagonist, ABT-627, or the dual endothelin A/B receptor antagonist, A-182086, the pressor response to CSS was similar between genotypes. CSS significantly increased plasma ET-1 levels in control mice that were homozygous for the floxed allele. CSS failed to elicit an increase in plasma ET-1 in vascular endothelium-specific ET-1 knockout mice. Telemetry frequency domain analyses suggested similar autonomic responses to stress between genotypes, and isolated resistance arteries demonstrated similar sensitivity to alpha1 adrenergic receptor-mediated vasoconstriction. CONCLUSIONS: These findings specify that acute stress-induced activation of endothelium-derived ET-1 and subsequent endothelin A receptor activation is a novel mediator of the blood pressure response to acute psychosocial stress.

AB - BACKGROUND: The incidence of obesity is rising, particularly among women. Microvascular dysfunction is more common with female sex, obesity, and hyperlipidemia and predicts adverse cardiovascular outcomes, but the molecular mechanisms are unclear. Because obesity is associated with mineralocorticoid receptor (MR) activation, we tested the hypothesis that MR in endothelial cells contribute to sex differences in resistance vessel dysfunction in response to cardiometabolic risk factors. METHODS AND RESULTS: Male and female endothelial cell-specific MR knockout mice and MR-intact littermates were randomized to high fat-diet-induced obesity or obesity with hyperlipidemia induced by adeno associated virus-based vector targeting transfer of the mutant stable form (DY mutation) of the human PCSK9 (proprotein convertase subtilisin/kexin type 9) gene and compared with control diet. Female but not male mice were sensitive to obesity-induced endothelial dysfunction, whereas endothelial function was impaired in obese hyperlipidemic males and females. In males, obesity or hyperlipidemia decreased the nitric oxide component of vasodilation without altering superoxide production or endothelial nitric oxide synthase expression or phosphorylation. Decreased nitric oxide content in obese males was overcome by enhanced endothelium-derived hyperpolarization-mediated relaxation along with increased SK3 expression. Conversely, in females, endothelium-derived hyperpolarization was significantly impaired by obesity with lower IK1 expression and by hyperlipidemia with lower IK1 and SK3 expression, loss of H2O2-mediated vasodilation, and increased superoxide production. Endothelial cell-MR deletion prevented endothelial dysfunction induced by risk factors only in females. Rather than restoring endothelium-derived hyperpolarization in females, endothelial cell MR deletion enhanced nitric oxide and prevented hyperlipidemia-induced oxidative stress. CONCLUSIONS: These data reveal distinct mechanisms driving resistance vessel dysfunction in males versus females and suggest that personalized treatments are needed to prevent the progression of vascular disease in the setting of obesity, depending on both the sex and the metabolic profile of each patient.

PMID- 29453309 TI - Sutureless Perceval Aortic Valve Versus Conventional Stented Bioprostheses: Meta Analysis of Postoperative and Midterm Results in Isolated Aortic Valve Replacement. AB - BACKGROUND: Aortic stenosis is the most common valvular disease and has a dismal prognosis without surgical treatment. The aim of this meta-analysis was to quantitatively assess the comparative effectiveness of the Perceval (LivaNova) valve versus conventional aortic bioprostheses. METHODS AND RESULTS: A total of 6 comparative studies were identified, including 639 and 760 patients who underwent, respectively, aortic valve replacement with the Perceval sutureless valve (P group) and with a conventional bioprosthesis (C group). Aortic cross clamping and cardiopulmonary bypass duration were significantly lower in the P group. No difference in postoperative mortality was shown for the P and C groups (2.8% versus 2.7%, respectively; odds ratio [OR]: 0.99 [95% confidence interval (CI), 0.52-1.88]; P=0.98). Incidence of postoperative renal failure was lower in the P group compared with the C group (2.7% versus 5.5%; OR: 0.45 [95% CI, 0.25 0.80]; P=0.007). Incidence of stroke (2.3% versus 1.7%; OR: 1.34 [95% CI, 0.56 3.21]; P=0.51) and paravalvular leak (3.1% versus 1.6%; OR: 2.52 [95% CI, 0.60 1.06]; P=0.21) was similar, whereas P group patients received fewer blood transfusions than C group patients (1.16+/-1.2 versus 2.13+/-2.2; mean difference: 0.99 [95% CI, -1.22 to -0.75]; P=0.001). The incidence of pacemaker implantation was higher in the P than the C group (7.9% versus 3.1%; OR: 2.45 [95% CI, 1.44-4.17]; P=0.001), whereas hemodynamic Perceval performance was better (transvalvular gradient 23.42+/-1.73 versus 22.8+/-1.86; mean difference: 0.90 [95% CI, 0.62-1.18]; P=0.001), even during follow-up (10.98+/-5.7 versus 13.06+/-6.2; mean difference: -2.08 [95% CI, -3.96 to -0.21]; P=0.030). We found no difference in 1-year mortality. CONCLUSIONS: The Perceval bioprosthesis improves the postoperative course compared with conventional bioprostheses and is an option for high-risk patients. PMID- 29453311 TI - Visualization of ligand-induced transmembrane signaling in the full-length human insulin receptor. AB - Insulin receptor (IR) signaling plays a critical role in the regulation of metabolism and growth in multicellular organisms. IRs are unique among receptor tyrosine kinases in that they exist exclusively as covalent (alphabeta)2 homodimers at the cell surface. Transmembrane signaling by the IR can therefore not be based on ligand-induced dimerization as such but must involve structural changes within the existing receptor dimer. In this study, using glycosylated full-length human IR reconstituted into lipid nanodiscs, we show by single particle electron microscopy that insulin binding to the dimeric receptor converts its ectodomain from an inverted U-shaped conformation to a T-shaped conformation. This structural rearrangement of the ectodomain propagates to the transmembrane domains, which are well separated in the inactive conformation but come close together upon insulin binding, facilitating autophosphorylation of the cytoplasmic kinase domains. PMID- 29453312 TI - Inhibition of Ras activity coordinates cell fusion with cell-cell contact during yeast mating. AB - In the fission yeast Schizosaccharomyces pombe, pheromone signaling engages a signaling pathway composed of a G protein-coupled receptor, Ras, and a mitogen activated protein kinase (MAPK) cascade that triggers sexual differentiation and gamete fusion. Cell-cell fusion requires local cell wall digestion, which relies on an initially dynamic actin fusion focus that becomes stabilized upon local enrichment of the signaling cascade on the structure. We constructed a live reporter of active Ras1 (Ras1-guanosine triphosphate [GTP]) that shows Ras activity at polarity sites peaking on the fusion structure before fusion. Remarkably, constitutive Ras1 activation promoted fusion focus stabilization and fusion attempts irrespective of cell pairing, leading to cell lysis. Ras1 activity was restricted by the guanosine triphosphatase-activating protein Gap1, which was itself recruited to sites of Ras1-GTP and was essential to block untimely fusion attempts. We propose that negative feedback control of Ras activity restrains the MAPK signal and couples fusion with cell-cell engagement. PMID- 29453313 TI - Multigene Profiling of CTCs in mCRPC Identifies a Clinically Relevant Prognostic Signature. AB - The trend toward precision-based therapeutic approaches dictated by molecular alterations offers substantial promise for men with metastatic castration resistant prostate cancer (mCRPC). However, current approaches for molecular characterization are primarily tissue based, necessitating serial biopsies to understand changes over time and are limited by the challenges inherent to extracting genomic material from predominantly bone metastases. Therefore, a circulating tumor cell (CTC)-based assay was developed to determine gene expression across a panel of clinically relevant and potentially actionable prostate cancer-related genes. CTCs were isolated from the whole blood of mCRPC patients (n = 41) and multiplex qPCR was performed to evaluate expression of prostate cancer-related target genes (n = 78). A large fraction of patients (27/41, 66%) had detectable CTCs. Increased androgen receptor (AR) expression (70% of samples) and evidence of Wnt signaling (67% of samples) were observed. The TMPRSS2:ERG fusion was expressed in 41% of samples, and the aggressive prostate cancer-associated long noncoding RNA SChLAP1 was upregulated in 70%. WNT5a [HR 3.62, 95% confidence interval (CI), 1.63-8.05, P = 0.002], AURKA (HR 5.56, 95% CI, 1.79-17.20, P = 0.003), and BMP7 (HR 3.86, 95% CI, 1.60-9.32, P = 0.003) were independently predictive of overall survival (FDR < 10%) after adjusting for a panel of previously established prognostic variables in mCRPC (Halabi nomogram). A model including Halabi, WNT5a, and AURKA expression, termed the miCTC score, outperformed the Halabi nomogram alone (AUC = 0.89 vs. AUC = 0.70). Understanding the molecular landscape of CTCs has utility in predicting clinical outcomes in patients with aggressive prostate cancer and provides an additional tool in the arsenal of precision-based therapeutic approaches in oncology.Implications: Analysis of CTC gene expression reveals a clinically prognostic "liquid biopsy" signature in patients with metastatic castrate resistance prostate cancer.

AB - Molecular drivers underlying bone metastases in human cancer are not well understood, in part due to constraints in bone tissue sampling. Here, RNA sequencing was performed of circulating tumor cells (CTC) isolated from blood samples of women with metastatic estrogen receptor (ER)+ breast cancer, comparing cases with progression in bone versus visceral organs. Among the activated cellular pathways in CTCs from bone-predominant breast cancer is androgen receptor (AR) signaling. AR gene expression is evident, as is its constitutively active splice variant AR-v7. AR expression within CTCs is correlated with the duration of treatment with aromatase inhibitors, suggesting that it contributes to acquired resistance to endocrine therapy. In an established breast cancer xenograft model, a bone-tropic derivative displays increased AR expression, whose genetic or pharmacologic suppression reduces metastases to bone but not to lungs. Together, these observations identify AR signaling in CTCs from women with bone predominant ER+ breast cancer, and provide a rationale for testing androgen inhibitors in this subset of patients.Implications: This study highlights a role for the AR in breast cancer bone metastasis, and suggests that therapeutic targeting of the AR may benefit patients with metastatic breast cancer.

AB - The Hedgehog (Hh) receptor Patched1 (PTCH1) is a well-known tumor suppressor that in its active form represses Smoothened (SMO) activity, inhibits proliferation, and induces apoptosis. The cytoplasmic C-terminal domain (CTD) regulates PTCH1 turnover and nucleates a proapoptotic complex. In this study, it was mechanistically determined that Autophagy-related 101 (ATG101), essential for mammalian autophagy, physically interacts with the CTD of PTCH1 and connects it to the ULK complex, which stimulates the autophagy machinery in response to changes in nutrient availability. This interaction results in a blockade of basal autophagic flux and accumulation of autophagosomes with undegraded cargo. Remarkably, this function of PTCH1 is independent of its repressive activity on SMO, as shown in SMO-deficient cells or in the presence of a SMO inhibitor, but is opposed by Sonic Hedgehog (SHH). These findings reveal a novel noncanonical function of PTCH1 that limits autophagy, mediated by ATG101, which could have therapeutic implications in Hh-dependent cancers.Implications: Loss-of-function of the tumor suppressor Patched1 might promote cancer cell fitness by increasing autophagic flux in response to metabolic or environmental stresses.

AB - Integrin alphaV gene expression is often dysregulated in cancers especially in hepatocellular carcinoma (HCC); however, the mechanism of regulation is poorly understood. Here, it is demonstrated that sulfatide activated integrin alphaV gene transcription, through histone H3K9/14 acetylation at the promoter, and high integrin alphaV expression are closely associated with poor prognosis. To elucidate the mechanism of regulation of acetylation, sulfatide-bound proteins were screened by mass spectrometry (MS), and bromodomain containing protein 1 (BRD1) was identified as an interacting protein that also colocalized with sulfatide in HCC cells. BRD1 was also formed a complex with Sp1, which was recruited to the integrin alphaV gene promoter. Sulfatide was also found to induce BRD1, monocytic leukemia zinc finger (MOZ) and histone acetyltransferase binding to ORC1 (HBO1) acetyltransferase multiprotein complex recruitment to the integrin alphaV promoter, which is responsible for histone H3K9/14 acetylation. Finally, knockdown of BRD1 limited sulfatide-induced H3K9/14 acetylation and occupancy of MOZ or HBO1 on integrin alphaV gene promoter.Implications: This study demonstrates that sulfatide interaction with BRD1 mediates acetylation and is important for regulation of integrin alphaV gene expression.

AB - Lysine to methionine mutations at position 27 (K27M) in the histone H3 (H3.3 and H3.1) are highly prevalent in pediatric high-grade gliomas (HGG) that arise in the midline of the central nervous system. H3K27M perturbs the activity of polycomb repressor complex 2 and correlates with DNA hypomethylation; however, the pathways whereby H3K27M drives the development of pediatric HGG remain poorly understood. To understand the mechanism of pediatric HGG development driven by H3.3K27M and discover potential therapeutic targets or biomarkers, we established pediatric glioma cell model systems harboring H3.3K27M and performed microarray analysis. H3.3K27M caused the upregulation of multiple cancer/testis (CT) antigens, such as ADAMTS1, ADAM23, SPANXA1, SPANXB1/2, IL13RA2, VCY, and VCX3A, in pediatric glioma cells. Chromatin immunoprecipitation analysis from H3.3K27M cells revealed decreased H3K27me3 levels and increased H3K4me3 levels on the VCX3A promoter. Knockdown of VCX3A by siRNA significantly inhibited the growth of pediatric glioma cells harboring H3.3K27M. Overexpression of VCX3A/B genes stimulated the expression of several HLA genes, including HLA-A, HLA-B, HLA-E, HLA-F, and HLA-G The expression of VCX3A in pediatric HGG was confirmed using a tissue microarray. Gene set enrichment analysis revealed that CT antigens are enriched in pediatric HGG clinical specimens with H3.3K27M, with the upregulation of IL13RA2 contributing to the enrichment significantly. These results indicate that the upregulation of CT antigens, such as VCX3A and IL13RA2, correlates with pediatric gliomagenesis. Mol Cancer Res; 16(4); 623-33. (c)2018 AACR. PMID- 29453318 TI - Integration of Distinct ShcA Signaling Complexes Promotes Breast Tumor Growth and Tyrosine Kinase Inhibitor Resistance. AB - The commonality between most phospho-tyrosine signaling networks is their shared use of adaptor proteins to transduce mitogenic signals. ShcA (SHC1) is one such adaptor protein that employs two phospho-tyrosine binding domains (PTB and SH2) and key phospho-tyrosine residues to promote mammary tumorigenesis. Receptor tyrosine kinases (RTK), such as ErbB2, bind the ShcA PTB domain to promote breast tumorigenesis by engaging Grb2 downstream of the ShcA tyrosine phosphorylation sites to activate AKT/mTOR signaling. However, breast tumors also rely on the ShcA PTB domain to bind numerous negative regulators that limit activation of secondary mitogenic signaling networks. This study examines the role of PTB independent ShcA pools in controlling breast tumor growth and resistance to tyrosine kinase inhibitors. We demonstrate that PTB-independent ShcA complexes predominately rely on the ShcA SH2 domain to activate multiple Src family kinases (SFK), including Src and Fyn, in ErbB2-positive breast cancers. Using genetic and pharmacologic approaches, we show that PTB-independent ShcA complexes augment mammary tumorigenesis by increasing the activity of the Src and Fyn tyrosine kinases in an SH2-dependent manner. This bifurcation of signaling complexes from distinct ShcA pools transduces non-redundant signals that integrate the AKT/mTOR and SFK pathways to cooperatively increase breast tumor growth and resistance to tyrosine kinase inhibitors, including lapatinib and PP2. This study mechanistically dissects how the interplay between diverse intracellular ShcA complexes impacts the tyrosine kinome to affect breast tumorigenesis.Implications: The ShcA adaptor, within distinct signaling complexes, impacts tyrosine kinase signaling, breast tumor growth, and resistance to tyrosine kinase inhibitors.

AB - Obesity is associated with poor prognosis in triple-negative breast cancer (TNBC). Preclinical models of TNBC were used to test the hypothesis that increased leptin signaling drives obesity-associated TNBC development by promoting cancer stem cell (CSC) enrichment and/or epithelial-to-mesenchymal transition (EMT). MMTV-Wnt-1 transgenic mice, which develop spontaneous basal like, triple-negative mammary tumors, received either a control diet (10% kcal from fat) or a diet-induced obesity regimen (DIO, 60% kcal from fat) for up to 42 weeks (n = 15/group). Mice were monitored for tumor development and euthanized when tumor diameter reached 1.5 cm. Tumoral gene expression was assessed via RNA sequencing (RNA-seq). DIO mice had greater body weight and percent body fat at termination than controls. DIO mice, versus controls, demonstrated reduced survival, increased systemic metabolic and inflammatory perturbations, upregulated tumoral CSC/EMT gene signature, elevated tumoral aldehyde dehydrogenase activity (a CSC marker), and greater leptin signaling. In cell culture experiments using TNBC cells (murine: E-Wnt and M-Wnt; human: MDA-MB 231), leptin enhanced mammosphere formation, and media supplemented with serum from DIO versus control mice increased cell viability, migration, invasion, and CSC- and EMT-related gene expression, including Foxc2, Twist2, Vim, Akt3, and Sox2 In E-Wnt cells, knockdown of leptin receptor ablated these procancer effects induced by DIO mouse serum. These findings indicate that increased leptin signaling is causally linked to obesity-associated TNBC development by promoting CSC enrichment and EMT.Implications: Leptin-associated signals impacting CSC and EMT may provide new targets and intervention strategies for decreasing TNBC burden in obese women.

AB - The cross-talk between epigenetics and miRNA expression plays an important role in human tumorigenesis. Herein, the regulation and role of miR-196b-5p in gastric cancer was investigated. qRT-PCR demonstrated that miR-196b-5p is significantly overexpressed in human gastric cancer tissues (P < 0.01). In addition, it was determined that HOXA10, a homeobox family member and host gene for miR-196b-5p, is overexpressed and positively correlated with miR-196b-5p expression levels (P < 0.001). Quantitative pyrosequencing methylation analysis demonstrated significantly lower levels of DNA methylation at the HOXA10 promoter in gastric cancer, as compared with nonneoplastic gastric mucosa specimens. 5-Aza-2' deoxycytidine treatment confirmed that demethylation of HOXA10 promoter induces the expression of HOXA10 and miR-196b-5p in gastric cancer cell model systems. Using the Tff1 knockout mouse model of gastric neoplasia, hypomethylation and overexpression of HOXA10 and miR-196b-5p in gastric tumors was observed, as compared with normal gastric mucosa from Tff1 wild-type mice. Mechanistically, reconstitution of TFF1 in human gastric cancer cells led to an increased HOXA10 promoter methylation with reduced expression of HOXA10 and miR-196b-5p. Functionally, miR-196b-5p reconstitution promoted human gastric cancer cell proliferation and invasion in vitro In summary, the current data demonstrate overexpression of miR-196b-5p in gastric cancer and suggest that TFF1 plays an important role in suppressing the expression of miR-196b-5p by mediating DNA methylation of the HOXA10 promoter. Loss of TFF1 expression may promote proliferation and invasion of gastric cancer cells through induction of promoter hypomethylation and expression of the HOXA10/miR-196b-5p axis.Implications: This study indicates that loss of TFF1 promotes the aberrant overexpression of HOXA10 and miR-196b-5p by demethylation of the HOXA10 promoter, which provides a new perspective of TFF1/HOXA10/miR-196b-5p functions in human gastric cancer.

AB - CD95 (Fas/APO-1), a death receptor family member, activity has been linked to tumorigenicity in multiple cancers, including glioblastoma multiforme (GBM). A phase II clinical trial on relapsed glioblastoma patients demonstrated that targeted inhibition of CD95 signaling via the CD95 ligand (CD95L) binding and neutralizing Fc-fusion protein APG101 (asunercept) prolonged patient survival. Although CD95 signaling may be relevant for multiple aspects of tumor growth, the mechanism of action of APG101 in glioblastoma is not clear. APG101 action was examined by in vitro proliferation, apoptosis, and invasion assays with human and murine glioma and human microglial cells, as well as in vivo therapy studies with orthotopic gliomas and clinical data. APG101 inhibits CD95L-mediated invasion of glioma cells. APG101 treatment was effective in glioma-bearing mice, independently of the presence or absence of CD4 and CD8 T lymphocytes, which should be sensitive to CD95L. Combined with radiotherapy, APG101 demonstrated a reduction of tumor growth, fewer tumor satellites, reduced activity of matrix metalloproteinases (MMP) as well as prolonged survival of tumor-bearing mice compared with radiotherapy alone. Inhibiting rather than inducing CD95 activity is a break-of-paradigm therapeutic approach for malignant gliomas. Evidence, both in vitro and in vivo, is provided that CD95L-binding fusion protein treatment enhanced the efficacy of radiotherapy and reduced unwanted proinfiltrative effects by reducing metalloproteinase activity by directly affecting the tumor cells.Implications: APG101 (asunercept) successfully used in a controlled phase II glioblastoma trial (NCT01071837) acts anti-invasively by inhibiting matrix metalloproteinase signaling, resulting in additive effects together with radiotherapy and helping to further develop a treatment for this devastating disease.

AB - The mTOR signaling pathway is a central regulator of protein synthesis and cellular metabolism in response to the availability of energy, nutrients, oxygen, and growth factors. mTOR activation leads to phosphorylation of multiple downstream targets including the eukaryotic initiation factor 4E (eIF4E) binding proteins-1 and -2 (EIF4EBP1/4E-BP1 and EIF4EBP2/4E-BP2). These binding proteins inhibit protein synthesis, but are inactivated by mTOR to stimulate cell growth and metabolism. However, the role of these proteins in the context of aberrant activation of mTOR, which occurs frequently in cancers through loss of PTEN or mutational activation of the PI3K/AKT pathway, is unclear. Here, even under conditions of aberrant mTOR activation, hypoxia causes dephosphorylation of 4E BP1/4E-BP2 and increases their association with eIF4E to suppress translation. This is essential for hypoxia tolerance as knockdown of 4E-BP1 and 4E-BP2 decreases proliferation under hypoxia and increases hypoxia-induced cell death. In addition, genetic deletion of 4E-BP1 and 4E-BP2 significantly accelerates all phases of cancer development in the context of PTEN loss-driven prostate cancer in mice despite potent PI3K/AKT and mTOR activation. However, even with a more rapid onset, tumors that establish in the absence of 4E-BP1 and 4E-BP2 have reduced levels of tumor hypoxia and show increased cell death within hypoxic tumor regions. Together, these data demonstrate that 4E-BP1 and 4E-BP2 act as essential metabolic breaks even in the context of aberrant mTOR activation and that they are essential for the creation of hypoxia-tolerant cells in prostate cancer.

PMID- 29453324 TI - Incidence and Predictors of Perioperative Complications With Transvenous Lead Extractions: Real-World Experience With National Cardiovascular Data Registry. AB - BACKGROUND: Transvenous lead extraction is an integral part of management of patients with cardiovascular implantable electronic devices. Real-world incidence and predictors of perioperative complications in extractions involving implantable cardioverter-defibrillator leads have not been described in detail. METHODS AND RESULTS: Data from the National Cardiovascular Data Registry Implantable Cardioverter-Defibrillator Registry were analyzed. Lead extraction was defined as removal of leads implanted for >1 year. Predictors of major perioperative complications for all extraction procedures (11 304) and for high voltage lead (8362, 74%), across 762 centers, were analyzed using univariate and multivariate logistic regression. Major complication occurred in 258 (2.3%) extraction procedures. Of these 258 with a complication, 41 (16%) required urgent cardiac surgery. Of these 41, 14 (34%) died during surgery. Among the total 98 (0.9%) deaths reported, 18 (0.16% of total) occurred during transvenous lead extraction. In multivariable logistic regression analysis, female sex, admission other than electively for procedure, >=3 leads extracted, longer implant duration, dislodgement of other leads, and patient's clinical status requiring lead extraction (infection/perforation) were associated with increased risk of complications. Smaller lead diameter, flat versus round coil shape, and greater proximal surface coil area were multivariate predictors of major perioperative complications specific to high-voltage leads. CONCLUSIONS: The rate of major complications and mortality with transvenous lead extraction is similar in the real-world outcomes to that reported in recent single-center studies from high volume centers. There is significant risk of urgent cardiac surgery, which carries a high mortality, and planning for appropriate cardiothoracic surgery backup is imperative. PMID- 29453323 TI - RNA-stabilization factors in chloroplasts of vascular plants. AB - In contrast to the cyanobacterial ancestor, chloroplast gene expression is predominantly governed on the post-transcriptional level such as modifications of the RNA sequence, decay rates, exo- and endonucleolytic processing as well as translational events. The concerted function of numerous chloroplast RNA-binding proteins plays a fundamental and often essential role in all these processes but our understanding of their impact in regulation of RNA degradation is only at the beginning. Moreover, metabolic processes and post-translational modifications are thought to affect the function of RNA protectors. These protectors contain a variety of different RNA-recognition motifs, which often appear as multiple repeats. They are required for normal plant growth and development as well as diverse stress responses and acclimation processes. Interestingly, most of the protectors are plant specific which reflects a fast-evolving RNA metabolism in chloroplasts congruent with the diverging RNA targets. Here, we mainly focused on the characteristics of known chloroplast RNA-binding proteins that protect exonuclease-sensitive sites in chloroplasts of vascular plants. PMID- 29453325 TI - Performance of the 2015 International Task Force Consensus Statement Risk Stratification Algorithm for Implantable Cardioverter-Defibrillator Placement in Arrhythmogenic Right Ventricular Dysplasia/Cardiomyopathy. AB - BACKGROUND: Ventricular arrhythmias are a feared complication of arrhythmogenic right ventricular dysplasia/cardiomyopathy. In 2015, an International Task Force Consensus Statement proposed a risk stratification algorithm for implantable cardioverter-defibrillator placement in arrhythmogenic right ventricular dysplasia/cardiomyopathy. METHODS AND RESULTS: To evaluate performance of the algorithm, 365 arrhythmogenic right ventricular dysplasia/cardiomyopathy patients were classified as having a Class I, IIa, IIb, or III indication per the algorithm at baseline. Survival free from sustained ventricular arrhythmia (VT/VF) in follow-up was the primary outcome. Incidence of ventricular fibrillation/flutter cycle length <240 ms was also assessed. Two hundred twenty four (61%) patients had a Class I implantable cardioverter-defibrillator indication; 80 (22%), Class IIa; 54 (15%), Class IIb; and 7 (2%), Class III. During a median 4.2 (interquartile range, 1.7-8.4)-year follow-up, 190 (52%) patients had VT/VF and 60 (16%) had ventricular fibrillation/flutter. Although the algorithm appropriately differentiated risk of VT/VF, incidence of VT/VF was underestimated (observed versus expected: 29.6 [95% confidence interval, 25.2 34.0] versus >10%/year Class I; 15.5 [confidence interval 11.1-21.6] versus 1% to 10%/year Class IIa). In addition, the algorithm did not differentiate survival free from ventricular fibrillation/flutter between Class I and IIa patients (P=0.97) or for VT/VF in Class I and IIa primary prevention patients (P=0.22). Adding Holter results (<1000 premature ventricular contractions/24 hours) to International Task Force Consensus classification differentiated risks. CONCLUSIONS: While the algorithm differentiates arrhythmic risk well overall, it did not distinguish ventricular fibrillation/flutter risks of patients with Class I and IIa implantable cardioverter-defibrillator indications. Limited differentiation was seen for primary prevention cases. As these are vital uncertainties in clinical decision-making, refinements to the algorithm are suggested prior to implementation.

PMID- 29453328 TI - Management of atrial fibrillation in patients with rheumatic mitral stenosis. AB - Atrial fibrillation (AF) is frequent in patients with rheumatic mitral stenosis (MS). Pressure overload leads to marked structural and electrical remodelling of left atrium. The frequency of persistent AF increases with age and paroxysmal, asymptomatic, AF seems even more frequent. The occurrence of AF worsens the haemodynamic tolerance of MS and markedly increases the risk of thromboembolic events. AF has a negative impact on the natural history of MS and on its outcome after commissurotomy. The respective indications of rhythm and rate control should be adapted to patient characteristics, particularly the consequences of MS, and take into account the high risk of recurrence of AF. Oral anticoagulant therapy is mandatory when AF complicates MS, regardless of its severity and CHA2DS2-VASc score. Non-vitamin K antagonists oral anticoagulants are not recommended in moderate-to-severe MS due to the lack of data. Percutaneous mitral commissurotomy does not appear to prevent the occurrence of AF in MS but should be considered as the first-line therapy when AF is associated with severe symptomatic MS, followed by the discussion of cardioversion or ablation. AF ablation should be considered in patients with mitral disease requiring intervention, but the ideal timing and techniques are difficult to determine due to the lack of appropriate specific randomised trials in patients with MS.

AB - BACKGROUND: Ischaemic heart disease is the leading cause of in-hospital mortality in Sri Lanka. Acute Coronary Syndrome Sri Lanka Audit Project (ACSSLAP) is the first national clinical-audit project that evaluated patient characteristics, clinical outcomes and care provided by state-sector hospitals. METHODS: ACSSLAP prospectively evaluated acute care, in-hospital care and discharge plans provided by all state-sector hospitals managing patients with ACS. Data were collected from 30 consecutive patients from each hospital during 2-4 weeks window. Local and international recommendations were used as audit standards. RESULTS: Data from 87/98 (88.7%) hospitals recruited 2177 patients, with 2116 confirmed as having ACS. Mean age was 61.4+/-11.8 years (range 20-95) and 58.7% (n=1242) were males. There were 813 (38.4%) patients with unstable angina, 695 (32.8%) with non ST-elevation myocardial infarction (NSTEMI) and 608 (28.7%) with ST-elevation myocardial infarction (STEMI). Both STEMI (69.9%) and NSTEMI (61.4%) were more in males (P<0.001). Aspirin, clopidogrel and statins were given to over 90% in acute setting and on discharge. In STEMI, 407 (66.9%) were reperfused; 384 (63.2%) were given fibrinolytics and only 23 (3.8%) underwent primary percutaneous coronary intervention (PCI). Only 42.3 % had thrombolysis in <30 min and 62.5% had PCI in <90 min. On discharge, beta-blockers and ACE inhibitors/angiotensin II receptor blockers were given to only 50.7% and 69.2%, respectively and only 17.6% had coronary interventions planned. CONCLUSIONS: In patients with ACS, aspirin, clopidogrel and statin use met audit standards in acute setting and on discharge. Vast majority of patients with STEMI underwent fibrinolyisis than PCI, due to limited resources. Primary PCI, planned coronary interventions and timely thrombolysis need improvement in Sri Lanka. PMID- 29453330 TI - Interphysician agreement on subclassification of myocardial infarction. AB - OBJECTIVE: The universal definition of myocardial infarction (MI) differentiates MI due to oxygen supply/demand mismatch (type 2) from MI due to plaque rupture (type 1) as well as from myocardial injuries of non-ischaemic or multifactorial nature. The purpose of this study was to investigate how often physicians agree in this classification and what factors lead to agreement or disagreement. METHODS: A total of 1328 patients diagnosed with MI at eight different Swedish hospitals 2011 were included. All patients were retrospectively reclassified into different MI or myocardial injury subtypes by two independent specially trained physicians, strictly adhering to the third universal definition of MI. RESULTS: Overall, there was a moderate interobserver agreement with a kappa coefficient (kappa) of 0.55 in this classification. There was substantial agreement when distinguishing type 1 MI (kappa: 0.61), compared with moderate agreement when distinguishing type 2 MI (kappa: 0.54). In multivariate logistic regression analyses, ST elevation MI (P<0.001), performed coronary angiography (P<0.001) and larger changes in troponin levels (P=0.023) independently made the physicians agree significantly more often, while they disagreed more often with symptoms of dyspnoea (P<0.001), higher systolic blood pressure (P=0.001) and higher C reactive protein levels on admission (P=0.016). CONCLUSION: Distinguishing MI types is challenging also for trained adjudicators. Although strictly adhering to the third universal definition of MI, differentiation between type 1 MI, type 2 MI and myocardial injury only gave a moderate rate of interobserver agreement. More precise and clinically applicable criteria for the current classification, particularly for type 2 MI diagnosis, are urgently needed. PMID- 29453331 TI - A Prospective Cohort Evaluation of the Cortisol Response to Cardiac Surgery with Occurrence of Early Postoperative Cognitive Decline. AB - BACKGROUND A recent study reported that patients with higher cortisol levels on the 1st postoperative morning after cardiac surgery exhibited an increased risk of early postoperative cognitive decline (POCD). Therefore, we conducted the current study to gain further insight into the stress response to a surgical procedure as a potential risk factor for early POCD after cardiac surgery. MATERIAL AND METHODS This prospective cohort study enrolled 125 patients undergoing elective cardiac surgery with or without cardiopulmonary bypass (CPB). Patient serum cortisol levels were determined 1 day before surgery (at 08: 00) and on the 1st (at 08: 00, 16: 00 and 24: 00), 3rd (at 08: 00), and 5th (at 08: 00) postoperative days. A battery of 9 neuropsychological tests were used to assess the participants 2 days before the surgical procedure and on the 6th postoperative day. POCD was defined as a decrease in performance of 1 SD or greater between the postoperative and preoperative z scores on at least 1 neuropsychological test. A mixed-design ANOVA was used to determine the correlations of the perioperative cortisol levels with the occurrence of POCD and with the surgical technique performed. RESULTS Mixed-design ANOVA showed no statistically significant differences in the cortisol levels between non-POCD and POCD patients (F=0.52, P=0.690) or between patients with and without CPB (F=2.02, P=0.103) at the 6 perioperative time points. CONCLUSIONS The occurrence of early POCD and the use of CPB were not associated with significantly higher cortisol levels in the repeated measurement design.

AB - With fossil representatives from the Silurian capable of respiring atmospheric oxygen, millipedes are among the oldest terrestrial animals, and likely the first to acquire diverse and complex chemical defenses against predators. Exploring the origin of complex adaptive traits is critical for understanding the evolution of Earth's biological complexity, and chemical defense evolution serves as an ideal study system. The classic explanation for the evolution of complexity is by gradual increase from simple to complex, passing through intermediate "stepping stone" states. Here we present the first phylogenetic-based study of the evolution of complex chemical defenses in millipedes by generating the largest genomic-based phylogenetic dataset ever assembled for the group. Our phylogenomic results demonstrate that chemical complexity shows a clear pattern of escalation through time. New pathways are added in a stepwise pattern, leading to greater chemical complexity, independently in a number of derived lineages. This complexity gradually increased through time, leading to the advent of three distantly related chemically complex evolutionary lineages, each uniquely characteristic of each of the respective millipede groups. PMID- 29453333 TI - Scleraxis is a transcriptional activator that regulates the expression of Tenomodulin, a marker of mature tenocytes and ligamentocytes. AB - Tenomodulin (Tnmd) is a type II transmembrane glycoprotein predominantly expressed in tendons and ligaments. We found that scleraxis (Scx), a member of the Twist-family of basic helix-loop-helix transcription factors, is a transcriptional activator of Tnmd expression in tenocytes. During embryonic development, Scx expression preceded that of Tnmd. Tnmd expression was nearly absent in tendons and ligaments of Scx-deficient mice generated by transcription activator-like effector nucleases-mediated gene disruption. Tnmd mRNA levels were dramatically decreased during serial passages of rat tenocytes. Scx silencing by small interfering RNA significantly suppressed endogenous Tnmd mRNA levels in tenocytes. Mouse Tnmd contains five E-box sites in the ~1-kb 5'-flanking region. A 174-base pair genomic fragment containing a TATA box drives transcription in tenocytes. Enhancer activity was increased in the upstream region (-1030 to -295) of Tnmd in tenocytes, but not in NIH3T3 and C3H10T1/2 cells. Preferential binding of both Scx and Twist1 as a heterodimer with E12 or E47 to CAGATG or CATCTG and transactivation of the 5'-flanking region were confirmed by electrophoresis mobility shift and dual luciferase assays, respectively. Scx directly transactivates Tnmd via these E-boxes to positively regulate tenocyte differentiation and maturation.

AB - Muography is a novel method to highly resolve the internal structure of active volcanoes by taking advantage of the cosmic muon's strong penetration power. In this paper, we present the first high-definition image in the vicinity of craters of an erupting volcano called Sakurajima, Kyushu, Japan. The muography observation system based on the technique of multi-wire proportional chamber (mMOS) has been operated reliably during the data taking period of 157 days. The mMOS measured precisely the flux of muons up to the thickness of 5,000 meter water-equivalent. It was shown that high-definition density maps around the Craters A, B and Showa could be determined with a precision of less than 7.5 * 7.5 m2 which earlier had not yet been achieved. The observed density distribution suggests that the fall back deposits filled the magma pathway and increased their density underneath Craters A and B. PMID- 29453334 TI - beta-catenin-independent regulation of Wnt target genes by RoR2 and ATF2/ATF4 in colon cancer cells. AB - Wnt signaling is an evolutionarily conserved signaling route required for development and homeostasis. While canonical, beta-catenin-dependent Wnt signaling is well studied and has been linked to many forms of cancer, much less is known about the role of non-canonical, beta-catenin-independent Wnt signaling. Here, we aimed at identifying a beta-catenin-independent Wnt target gene signature in order to understand the functional significance of non-canonical signaling in colon cancer cells. Gene expression profiling was performed after silencing of key components of Wnt signaling pathway and an iterative signature algorithm was applied to predict pathway-dependent gene signatures. Independent experiments confirmed several target genes, including PLOD2, HADH, LCOR and REEP1 as non-canonical target genes in various colon cancer cells. Moreover, non canonical Wnt target genes are regulated via RoR2, Dvl2, ATF2 and ATF4. Furthermore, we show that the ligands Wnt5a/b are upstream regulators of the non canonical signature and moreover regulate proliferation of cancer cells in a beta catenin-independent manner. Our experiments indicate that colon cancer cells are dependent on both beta-catenin-dependent and -independent Wnt signaling routes for growth and proliferation. PMID- 29453338 TI - Revisiting the Pacific Meridional Mode. AB - Numerous studies demonstrated that the Pacific Meridional Mode (PMM) can excite Central Pacific (CP) El Nino-Southern Oscillation (ENSO) events and that the PMM is mostly a stochastic phenomenon associated with mid-latitude atmospheric variability and wind-evaporation-SST feedback. Here we show that CP sea surface temperature (SST) variability exhibits high instantaneous correlations both on interannual (ENSO-related) and decadal (Pacific Decadal Oscillation (PDO) related) timescales with the PMM. By prescribing an idealized interannual equatorial CP ENSO SST forcing in a partially-coupled atmosphere/slab ocean model we are able to generate a realistic instantaneous PMM response consistent with the observed statistical ENSO/PMM relationship. This means that CP ENSO and the PMM can excite each other respectively on interannual timescales, strongly suggesting that a fast positive feedback exists between the two phenomena. Thus, we argue that they cannot be considered two independent dynamical entities. Additionally, we show that the interannual CP ENSO SST forcing generates atmospheric circulation variability that projects strongly on the Aleutian Low and North Pacific SST anomalies that exhibit the characteristic PDO pattern. PMID- 29453336 TI - Alternative splicing of ALCAM enables tunable regulation of cell-cell adhesion through differential proteolysis. AB - While many adhesion receptors are known to influence tumor progression, the mechanisms by which they dynamically regulate cell-cell adhesion remain elusive. We previously identified Activated Leukocyte Cell Adhesion Molecule (ALCAM) as a clinically relevant driver of metastasis and hypothesized that a tunable mechanism of ectodomain shedding regulates its contribution to dissemination. To test this hypothesis, we examined an under-explored ALCAM splice variant (ALCAM Iso2) and demonstrated that loss of the membrane-proximal region of ALCAM (exon 13) increased metastasis four-fold. Mechanistic studies identified a novel MMP14 dependent membrane distal cleavage site in ALCAM-Iso2, which mediated a ten-fold increase in shedding, thereby decreasing cellular cohesion. Importantly, the loss of cohesion is not limited to the cell capable of shedding because the released extracellular domain diminished cohesion of non-shedding cells through disruption of ALCAM-ALCAM interactions. ALCAM-Iso2-dominated expression in bladder cancer tissue, compared to normal bladder, further emphasizes that ALCAM alternative splicing may contribute to clinical disease progression. The requirement for both the loss of exon 13 and the gain of metalloprotease activity suggests that ALCAM shedding and concomitant regulation of tumor cell adhesion is a locally tunable process. PMID- 29453337 TI - p66Shc Signaling Mediates Diabetes-Related Cognitive Decline. AB - Accumlating evidence have suggested that diabetes mellitus links dementia, notably of Alzheimer's disease (AD). However, the underlying mechanism remains unclear. Several studies have shown oxidative stress (OS) to be one of the major factors in the pathogenesis of diabetic complications. Here we show OS involvement in brain damage in a diabetic animal model that is at least partially mediated through an AD-pathology-independent mechanism apart from amyloid-beta accumulation. We investigated the contribution of the p66Shc signaling pathway to diabetes-related cognitive decline using p66Shc knockout (-/-) mice. p66Shc (-/-) mice have less OS in the brain and are resistant to diabetes-induced brain damage. Moreover, p66Shc (-/-) diabetic mice show significantly less cognitive dysfunction and decreased levels of OS and the numbers of microglia. This study postulates a p66Shc-mediated inflammatory cascade leading to OS as a causative pathogenic mechanism in diabetes-associated cognitive impairment that is at least partially mediated through an AD-pathology-independent mechanism. PMID- 29453340 TI - Elevated nitrogen allows the weak invasive plant Galinsoga quadriradiata to become more vigorous with respect to inter-specific competition. AB - Elevated nitrogen associated with global change is believed to promote the invasion of many vigorous exotic plants. However, it is unclear how a weak exotic plant will respond to elevated nitrogen in the future. In this study, the competitive outcome of a weak invasive plant (Galinsoga quadriradiata) and two non-invasive plants was detected. The plants were subjected to 3 types of culture (mixed, monoculture or one-plant), 2 levels of nitrogen (ambient or elevated at a rate of 2 g m-2 yr-1) and 2 levels of light (65% shade or full sunlight). The results showed that elevated nitrogen significantly promoted the growth of both the weak invader and the non-invasive plants in one-plant pots; however, growth promotion was not observed for the non-invasive species in the mixed culture pots. The presence of G. quadriradiata significantly inhibited the growth of the non-invasive plants, and a decreased negative species interaction was detected as a result of elevated nitrogen. Our results suggest that competitive interactions between G. quadriradiata and the non-invasive plants were altered by elevated nitrogen. It provides exceptional evidence that an initially weak invasive plant can become an aggressive invader through elevated nitrogen deposition. PMID- 29453339 TI - A role for tau in learning, memory and synaptic plasticity. AB - Tau plays a pivotal role in the pathogenesis of neurodegenerative disorders: mutations in the gene encoding for tau (MAPT) are linked to Fronto-temporal Dementia (FTD) and hyper-phosphorylated aggregates of tau forming neurofibrillary tangles (NFTs) that constitute a pathological hallmark of Alzheimer disease (AD) and FTD. Accordingly, tau is a favored therapeutic target for the treatment of these diseases. Given the criticality of tau to dementia's pathogenesis and therapy, it is important to understand the physiological function of tau in the central nervous system. Analysis of Mapt knock out (Mapt-/-) mice has yielded inconsistent results. Some studies have shown that tau deletion does not alter memory while others have described synaptic plasticity and memory alterations in Mapt-/- mice. To help clarifying these contrasting results, we analyzed a distinct Mapt-/- model on a B6129PF3/J genetic background. We found that tau deletion leads to aging-dependent short-term memory deficits, hyperactivity and synaptic plasticity defects. In contrast, Mapt+/- mice only showed a mild short memory deficit in the novel object recognition task. Thus, while tau is important for normal neuronal functions underlying learning and memory, partial reduction of tau expression may have fractional deleterious effects. PMID- 29453341 TI - Transcriptomics reveals a cross-modulatory effect between riboflavin and iron and outlines responses to riboflavin biosynthesis and uptake in Vibrio cholerae. AB - Vibrio cholerae, a pandemic diarrheagenic bacterium, is able to synthesize the essential vitamin riboflavin through the riboflavin biosynthetic pathway (RBP) and also to internalize it through the RibN importer. In bacteria, the way riboflavin biosynthesis and uptake functions correlate is unclear. To gain insights into the role of the riboflavin provision pathways in the physiology of V. cholerae, we analyzed the transcriptomics response to extracellular riboflavin and to deletions of ribD (RBP-deficient strain) or ribN. Many riboflavin responsive genes were previously reported to belong to the iron regulon, including various iron uptake genes. Real time PCR analysis confirmed this effect and further documented that reciprocally, iron regulates RBP and ribN genes in a riboflavin-dependent way. A subset of genes were responding to both ribD and ribN deletions. However, in the subset of genes specifically affected in the ?ribD strain, the functional terms protein folding and oxidation reduction process were enriched, as determined by a Gene Ontology analysis. In the gene subset specifically affected in the ?ribN strain, the cytochrome complex assembly functional term was enriched. Results suggest that iron and riboflavin interrelate to regulate its respective provision genes and that both common and specific effects of biosynthesized and internalized riboflavin exist. PMID- 29453342 TI - Prediction of coronary disease incidence by biomarkers of inflammation, oxidation, and metabolism. AB - The effect of circulating biomarkers in predicting coronary artery disease (CAD) is not fully elucidated. This study aimed to determine the relationship with CAD and the predictive capacity of nine biomarkers of inflammation (TNF-alpha, IL-10, IL-6, MCP-1, CRP), oxidation (GHS-Px), and metabolism (adiponectin, leptin, and insulin). This was a case-cohort study, within the REGICOR population-cohorts (North-Eastern Spain), of 105 CAD cases and 638 individuals randomly selected from a cohort of 5,404 participants aged 35-74 years (mean follow-up = 6.1 years). Biomarkers' hazard ratio (HR)/standard deviation was estimated with Cox models adjusted for age, sex, and classical risk factors. Discrimination improvement and reclassification were analyzed with the c-index and the Net reclassification index (NRI). GHS-Px (adjusted HRs = 0.77; 95%CI:0.60-0.99), insulin (1.46; 1.08-1.98), leptin (1.40; 1.03-1.90), IL-6 (1.34; 1.03-1.74), and TNF-alpha (1.80; 1.26-2.57) were significantly associated with CAD incidence. In the model adjusted for all biomarkers, TNF-alpha (1.87;1.31-2.66) and insulin (1.59;1.16-2.19) were independently associated with CAD. This final model, compared to a model without biomarkers, showed a c-index difference of 1.3% ( 0.7, 3.2) and a continuous NRI of 33.7% (2.6, 61.9). TNF-alpha and insulin are independently associated with CAD incidence and they improve reclassification when added to a model including classical risk factors. PMID- 29453343 TI - Effect of chronic exercise on fluoride metabolism in fluorosis-susceptible mice exposed to high fluoride. AB - The present study investigated the effect of chronic exercise on fluoride (F) metabolism in fluorosis-susceptible mice exposed to high-F and explored the relationship between F concentrations in bone and plasma. Thirty male mice were randomised into three groups: Group I (No-F, No-Exercise), Group II (50 ppmF, No Exercise), Group III (50 ppmF, Exercise). Body weight and physical performance of all mice were measured at baseline and end of experiment. F concentrations of plasma and bone were measured at the end of experiment. Mean plasma F concentration was significantly higher (p < 0.001) in Groups II and III compared with Group I. Mean bone F concentration was also significantly higher (p < 0.01) in Groups II and III compared with Group I. There was a significant correlation (p = 0.01, r = 0.54) between F concentration of plasma and bone. Mean body weight of Group I mice was significantly higher than Group II (p < 0.001) and Group III (p = 0.001) mice at the end of the experiment. This study, which provides the first data on the effect of chronic exercise on F metabolism in fluorosis susceptible mice, suggests no effect of chronic exercise on F in plasma and bone. However, exposure to high-F resulted in lower body weight and exercise capacity in mice.

AB - Electrocaloric (EC) refrigeration, an EC effect based technology has been accepted as an auspicious way in the development of next generation refrigeration due to high efficiency and compact size. Here, we report the results of our experimental investigations on electrocaloric response and electrical energy storage properties in lead-free nanocrystalline (1 - x)K0.5Na0.5NbO3-xLiSbO3 (KNN xLS) ceramics in the range of 0.015 <= x <= 0.06 by the indirect EC measurements. Doping of LiSbO3 has lowered both the transitions (T C and TO-T) of KNN to the room temperature side effectively. A maximal value of EC temperature change, DeltaT = 3.33 K was obtained for the composition with x = 0.03 at 345 K under an external electric field of 40 kV/cm. The higher value of EC responsivity, zeta = 8.32 * 10-7 K.m/V is found with COP of 8.14 and recoverable energy storage of 0.128 J/cm3 with 46% efficiency for the composition of x = 0.03. Our investigations show that this material is a very promising candidate for electrocaloric refrigeration and energy storage near room temperature. PMID- 29453345 TI - Short-term acclimation in adults does not predict offspring acclimation potential to hypoxia. AB - The prevalence of hypoxic areas in coastal waters is predicted to increase and lead to reduced biodiversity. While the adult stages of many estuarine invertebrates can cope with short periods of hypoxia, it remains unclear whether that ability is present if animals are bred and reared under chronic hypoxia. We firstly investigated the effect of moderate, short-term environmental hypoxia (40% air saturation for one week) on metabolic performance in adults of an estuarine amphipod, and the fitness consequences of prolonged exposure. We then reared the offspring of hypoxia-exposed parents under hypoxia, and assessed their oxyregulatory ability under declining oxygen tensions as juveniles and adults. Adults from the parental generation were able to acclimate their metabolism to hypoxia after one week, employing mechanisms typically associated with prolonged exposure. Their progeny, however, did not develop the adult pattern of respiratory regulation when reared under chronic hypoxia, but instead exhibited a poorer oxyregulatory ability than their parents. We conclude that species apparently hypoxia-tolerant when tested in short-term experiments, could be physiologically compromised as adults if they develop under hypoxia. Consequently, we propose that the increased prevalence of hypoxia in coastal regions will have marked effects in some species currently considered hypoxia tolerant. PMID- 29453346 TI - Anti-inflammatory effect of Tauroursodeoxycholic acid in RAW 264.7 macrophages, Bone marrow-derived macrophages, BV2 microglial cells, and spinal cord injury. AB - This study aimed to investigate the anti-inflammatory effects of tauroursodeoxycholic acid (TUDCA) after spinal cord injury (SCI) in rats. We induced an inflammatory process in RAW 264.7 macrophages, BV2 microglial cells, and bone marrow-derived macrophages (BMM) using lipopolysaccharide (LPS). The anti-inflammatory effects of TUDCA on LPS-stimulated RAW 264.7 macrophages, BV2 microglial cells, and BMMs were analyzed using nitric oxide (NO) assays, quantitative real-time polymerase chain reactions (qRT-PCR), and enzyme-linked immunosorbent assays (ELISA). The pathological changes in lesions of the spinal cord tissue were evaluated by hematoxylin & eosin (H&E) staining, luxol fast blue/cresyl violet-staining and immunofluorescent staining. TUDCA decreased the LPS-stimulated inflammatory mediator, NO. It also suppressed pro-inflammatory cytokines of tumor necrosis factor-alpha (TNF-alpha), interleukin 1-beta (IL 1beta), cyclooxygenase-2 (COX-2), and inducible nitric oxide synthase (iNOS) in both mRNA and protein levels. In addition, TUDCA decreased prostaglandin E2 (PGE2). After SCI, TUDCA supported the recovery of the injury site and suppressed the expression of inflammatory cytokines such as iNOS, CD68 and CD86. In addition, TUDCA induced the expression of anti-inflammatory cytokine, Arg-1. In conclusion, TUDCA inhibits inflammatory responses in RAW 264.7 macrophages, BV2 microglial cells, and BMMs. TUDCA can be a potential alternative drug for SCI. PMID- 29453347 TI - Reversing Coffee-Ring Effect by Laser-Induced Differential Evaporation. AB - The coffee-ring effect, ubiquitously present in the drying process of aqueous droplets, impedes the performance of a myriad of applications involving precipitation of particle suspensions in evaporating liquids on solid surfaces, such as liquid biopsy combinational analysis, microarray fabrication, and ink-jet printing, to name a few. We invented the methodology of laser-induced differential evaporation to remove the coffee-ring effect. Without any additives to the liquid or any morphology modifications of the solid surface the liquid rests on, we have eliminated the coffee-ring effect by engineering the liquid evaporation profile with a CO2 laser irradiating the apex of the droplets. The method of laser-induced differential evaporation transitions particle deposition patterns from coffee-ring patterns to central-peak patterns, bringing all particles (e.g. fluorescent double strand DNAs) in the droplet to a designated area of 100 MUm diameter without leaving any stains outside. The technique also moves the drying process from the constant contact radius (CCR) mode to the constant contact angle (CCA) mode. Physical mechanisms of this method were experimentally studied by internal flow tracking and surface evaporation flux mapping, and theoretically investigated by development of an analytical model. PMID- 29453348 TI - ABCG2 contributes to the development of gout and hyperuricemia in a genome-wide association study. AB - Although many genome-wide association studies (GWASs) of hyperuricemia or gout have been reported, the related genetic factors and the mechanisms from hyperuricemia to gouty attack remain unclear. This study aimed to identify genetic factors and pathogenesis of gout from hyperuricemia by genome-wide association study (GWAS). 747 gout patients, 747 hyperuricemia and 2071 age matched controls were recruited and analyzed with Affymetrix 650 K chip to find the related genetic variants. The functions of the related genes were investigated in an endothelial cell (EC) with urate crystal stimulation. The GWAS results showed 36 SNPs to be strongly associated with gout compared to controls (all p-values < 10-7). Whereas the rs2231142 in ABCG2 gene had significant associations between gout and controls, between gout and hyperuricemia, and between hyperuricemia and controls (all p-values < 10-7), and the ORs were 4.34, 3.37 and 2.15 (all p-values < 0.001) after adjustment of potential confounders, respectively. The cell model showed significantly higher IL-8 release from EC combined with ABCG2 knockdown. We concluded that ABCG2 gene contributed to hyperuricemia but also gout, and that it was involved in the inflammation dysregulation via augmented IL-8 release in EC.

To allow ecologists and evolutionary biologists to confidently find and use the existing data, we provide an overview of the landscape of online data infrastructures, and highlight the key points to consider when using open data. We introduce an online collaborative platform to keep a community-driven, updated list of the best sources that enable search for data in one interface. In doing so, our aim is to lower the barrier to accessing open data, and encourage its use by researchers hoping to increase the scope, reliability and value of their findings. PMID- 29453349 TI - Ultrasound and shock-wave stimulation to promote axonal regeneration following nerve surgery: a systematic review and meta-analysis of preclinical studies. AB - Limited regeneration after nerve injury often leads to delayed or incomplete reinnervation and consequently insufficient muscle function. Following nerve surgery, application of low-intensity ultrasound or extracorporeal shock waves may promote nerve regeneration and improve functional outcomes. Because currently clinical data is unavailable, we performed a meta-analysis following the PRISMA guidelines to investigate the therapeutic effect of ultrasound and shock wave therapies on motor nerve regeneration. Ten ultrasound-studies (N = 445 rats) and three shock-wave studies (N = 110 rats) were identified from multiple databases. We calculated the difference in means or standardized mean difference with 95% confidence intervals for motor function, nerve conduction velocity and histomorphological parameters of treated versus sham or non-treated animals. Ultrasound treatment showed significantly faster nerve conduction, increased axonal regeneration with thicker myelin and improved motor function on sciatic functional index scale (week two: DM[95%CI]: 19,03[13,2 to 25,6], 71 animals; week four: 7,4[5,4 to 9,5], 47 animals). Shock wave induced recovery improvements were temporarily significant. In conclusion, there is significant evidence for low-intensity ultrasound but not for extracorporeal shock wave treatment to improve nerve regeneration. Prospective clinical trials should therefore investigate available FDA-approved ultrasound devices as adjunct postoperative treatment following nerve surgery.

AB - Recent years have seen a surge of interest in ecosystem multifunctionality, a concept that has developed in the largely separate fields of biodiversity ecosystem function and land management research. Here we discuss the merit of the multifunctionality concept, the advances it has delivered, the challenges it faces and solutions to these challenges. This involves the redefinition of multifunctionality as a property that exists at two levels: ecosystem function multifunctionality and ecosystem service multifunctionality. The framework presented provides a road map for the development of multifunctionality measures that are robust, quantifiable and relevant to both fundamental ecological science and ecosystem management.

AB - Polymorphism is a key feature of amyloid fibril structures but it remains challenging to explain these variations for a particular sample. Here, we report electron cryomicroscopy-based reconstructions from different fibril morphologies formed by a peptide fragment from an amyloidogenic immunoglobulin light chain. The observed fibril morphologies vary in the number and cross-sectional arrangement of a structurally conserved building block. A comparison with the theoretically possible constellations reveals the experimentally observed spectrum of fibril morphologies to be governed by opposing sets of forces that primarily arise from the beta-sheet twist, as well as peptide-peptide interactions within the fibril cross-section. Our results provide a framework for rationalizing and predicting the structure and polymorphism of cross-beta fibrils, and suggest that a small number of physical parameters control the observed fibril architectures.

AB - Antarctic coastal polynyas are regions of persistent open water and are thought to be key bio-physical features within the sea-ice zone. However, their use by the upper trophic levels of ecosystems remains unclear. A unique bio-physical dataset recorded by southern elephant seals reveals that East Antarctic polynyas are a key winter foraging habitat for male seals. During their post-moult trips from Isles Kerguelen to the Antarctic continental shelf, a total of 18 out of 23 seals visited 9 different polynyas, spending on average 25 +/- 20% (up to 75%) of their total trip time inside polynyas. Changes in seal foraging and diving behaviours are observed inside polynyas as compared to outside polynyas. Two polynya usages by seals are observed for the inactive and active polynya phases, pointing to different seasonal peaks in prey abundance. During the active polynya phase, we link seal foraging behaviour to changes in the physical stability of the water-column, which likely impact the seasonal biological dynamics within polynyas.

AB - Arabidopsis thaliana Toxicos en Levadura (ATL) proteins are a subclass of the RING-H2 zinc finger binding E3 ubiquitin ligases. The grapevine (Vitis vinifera) ATL family was recently characterized, revealing 96 members that are likely to be involved in several physiological processes through protein ubiquitination. However, the final targets and biological functions of most ATL E3 ligases are still unknown. We analyzed the co-expression networks among grapevine ATL genes across a set of transcriptomic data related to defense and abiotic stress, combined with a condition-independent dataset. This revealed strong correlations between ATL proteins and diverse signal transduction components and transcriptional regulators, in particular those involved in immunity. An enrichment analysis of cis-regulatory elements in ATL gene promoters and related co-expressed genes highlighted the importance of hormones in the regulation of ATL gene expression. Our work identified several ATL proteins as candidates for further studies aiming to decipher specific grapevine resistance mechanisms activated in response to pathogens.

AB - Fidgeting, defined as the generation of small movements through nervousness or impatience, is one of cardinal characteristic of ADHD. While fidgeting is, by definition, a motor experience still nothing is known about the effects of fidgeting on motor control. Some forms of fidgeting involve also the manipulation of external objects which, through repetition, may become automatic and second nature. Both repetition and practice are important for the acquisition of motor skills and, therefore, it is plausible that the repetitive manipulation of objects may influence motor control and performance. As such, fidget spinners, by being diffuse and prone to repetitive usage, may represent interesting tool for improving motor control. In this study we examine the effect of fidget spinners on fine motor control, evaluated by a spiral-tracing task. We show that the use of fidget spinner indeed seems to have a favorable effect on fine motor control, at least in the short term, although this effect does not seem to be in any way inherent to fidget spinners themselves as much as to object manipulation in general. However, due to their widespread usage, fidget spinner may have the advantage of being an enjoyable means for improving fine motor control.

In all of these fields, highly specialized and often expensive analysis is usually combined with expert interpretation to estimate sample origin. In this proof of concept study we apply rapid and non destructive spectral analysis to the question of direct soil provenancing. This approach is based on one of the underlying tenets of soil science - that soil pedogenesis is spatially unique, and thus digital spectral signatures of soil can be related directly, rather than via individual soil properties, to a georeferenced location. We examine three different multivariate regression techniques to predict GPS coordinates in two nested datasets. With a minimum of data processing, we show that in most instances Eastings and Northings can be predicted to within 20% of the range of each within the dataset using the spectral signatures produced via portable x-ray fluorescence. We also generate 50 and 95% confidence intervals of prediction and express these as a range of GPS coordinates. This approach has promise for future application in soil and environmental provenancing. PMID- 29453359 TI - Rational Construction of Uniform CoNi-Based Core-Shell Microspheres with Tunable Electromagnetic Wave Absorption Properties. AB - Core-shell particles with integration of ferromagnetic core and dielectric shell are attracting extensive attention for promising microwave absorption applications. In this work, CoNi microspheres with conical bulges were synthesized by a simple and scalable liquid-phase reduction method. Subsequent coating of dielectric materials was conducted to acquire core-shell structured CoNi@TiO2 composite particles, in which the thickness of TiO2 is about 40 nm. The coating of TiO2 enables the absorption band of CoNi to effectively shift from Ku to S band, and endows CoNi@TiO2 microspheres with outstanding electromagnetic wave absorption performance along with a maximum reflection loss of 76.6 dB at 3.3 GHz, much better than that of bare CoNi microspheres (54.4 dB at 17.8 GHz). The enhanced EMA performance is attributed to the unique core-shell structures, which can induce dipole polarization and interfacial polarization, and tune the dielectric properties to achieve good impedance matching. Impressively, TiO2 coating endows the composites with better microwave absorption capability than CoNi@SiO2 microspheres. Compared with SiO2, TiO2 dielectric shells could protect CoNi microspheres from merger and agglomeration during annealed. These results indicate that CoNi@TiO2 core-shell microspheres can serve as high-performance absorbers for electromagnetic wave absorbing application. PMID- 29453360 TI - Role of intestinal trefoil factor in protecting intestinal epithelial cells from burn-induced injury. AB - Although intestinal trefoil factor (ITF) can alleviate the burn-induced intestinal mucosa injury, the underlying mechanisms remains elusive. In this study, we investigated if ITF alters glutamine transport on the brush border membrane vesicles (BBMVs) of the intestines in Sprague-Dawley rats inflicted with 30% TBSA and the underlying mechanisms. We found that ITF significantly stimulated intestinal glutamine transport in burned rats. Mechanistically, ITF enhanced autophagy, reduces endoplasmic reticulum stress (ERS), and alleviates the impaired PDI, ASCT2, and B0AT1 in IECs and BBMVs after burn injury likely through AMPK activation. Therefore, ITF may protect intestinal epithelial cells from burn-induced injury through improving glutamine transport by alleviating ERS. PMID- 29453361 TI - Heterogeneity and mutation in KRAS and associated oncogenes: evaluating the potential for the evolution of resistance to targeting of KRAS G12C. AB - Activating mutations in RAS genes are associated with approximately 20% of all human cancers. New targeted therapies show preclinical promise in inhibiting the KRAS G12C variant. However, concerns exist regarding the effectiveness of such therapies in vivo given the possibilities of existing intratumor heterogeneity or de novo mutation leading to treatment resistance. We performed deep sequencing of 27 KRAS G12-positive lung tumors to determine the prevalence of other oncogenic mutations within KRAS or within commonly mutated downstream genes that could confer resistance at the time of treatment. We also passaged patient-derived xenografts to assess the potential for novel KRAS mutation to arise during subsequent tumor evolution. Furthermore, we estimate the de novo mutation rate in KRAS position 12 and in genes downstream of KRAS. Finally, we present an approach for estimation of the selection intensity for these point mutations that explains their high prevalence in tumors. We find no evidence of heterogeneity that may compromise KRAS G12C targeted therapy within sequenced lung tumors or passaged xenografts. We find that mutations that confer resistance are even less likely to occur downstream of KRAS than to occur within KRAS. Our approach predicts that BRAF V600E would provide the highest fitness advantage for de novo-resistant subclones. Overall, our findings suggest that resistance to targeted therapy of KRAS G12C-positive tumors is unlikely to be present at the time of treatment and, among the de novo mutations likely to confer resistance, mutations in BRAF, a gene with targeted inhibitors presently available, result in subclones with the highest fitness advantage. PMID- 29453362 TI - Long-term bladder and bowel management after spinal cord injury: a 20-year longitudinal study. AB - STUDY DESIGN: Prospective observational. AIM: The aim of this study was to analyse changes in bladder and bowel management methods in persons with long standing spinal cord injury (SCI). SETTING: Two spinal centres in UK. METHOD: Data were collected through interviews and examinations between 1990 and 2010 in a sample of persons injured more than 20 years prior to 1990. RESULTS: For the 85 participants who completed the 2010 follow-up, the mean age was 67.7 years and the mean duration of injury was 46.3 years, 80% were male, 37.7% had tetraplegia AIS grade A, B, or C, 44.7% paraplegia AIS A, B, or C, and 17.6% an AIS D grade regardless of level. In all, 50.6% reported having changed their bladder method, 63.1% their bowel method, and 40.5% both methods since they enroled in the study. The reasons for change were a combination of medical and practical. In men, condom drainage remained the most frequent bladder method, and in women, suprapubic catheter replaced straining/expressing as the most frequent method. The use of condom drainage and straining/expressing bladder methods decreased, whereas the use of suprapubic and intermittent catheters increased. Manual evacuation remained the most frequent bowel management method. The percentage of participants on spontaneous/voluntary bowel emptying, straining and medications alone decreased, whereas the use of colostomy and transanal irrigation increased over time. CONCLUSIONS: More than half the sample, all living with SCI for more than 40 years, required change in their bladder and bowel management methods, for either medical or practical reasons. Regular follow-ups ensure adequate change of method if/when needed. PMID- 29453363 TI - Guiding of laser pulses in plasma waveguides created by linearly-polarized femtosecond laser pulses. AB - We experimentally demonstrate that plasma waveguides produced with ultra-short laser pulses (sub-picosecond) in gas jets are capable of guiding high intensity laser pulses. This scheme has the unique ability of guiding a high-intensity laser pulse in a plasma waveguide created by the same laser system in the very simple and stable experimental setup. A hot plasma column was created by a femtosecond class laser that expands into an on-axis parabolic low density profile suitable to act as a waveguide for high intensity laser beams. We have successfully guided ~1015 W cm-2 laser pulses in a 8 mm long hydrogen plasma waveguide with a 35% guiding efficiency. PMID- 29453365 TI - High fidelity heralded single-photon source using cavity quantum electrodynamics. AB - Demands for single-photon sources are ubiquitous in quantum information processing as well as in quantum metrology. In many protocols for producing single photons, a cavity-emitter configuration is used. In such cavity quantum electrodynamical systems, the cavity can enforce a well-defined output mode for the photon and enhance its collection efficiency, while the emitter is indispensable for single photon emission. Here we show the two cavity-one two level emitter configuration can be used to produce exclusively photon pairs, with each photon in a separate mode. Conditioning on detecting a photon in one of the modes, one heralds with high fidelity a single photon in the other mode. Counterintuitively, upon decreasing the coupling of the emitter to one of the modes, the heralding fidelity can further increase. PMID- 29453367 TI - Quantitative Analysis of Charge Distribution in Bi-Emissive layer White Organic Light-Emitting Diodes with Two Fluorescent Dopants. AB - This work seeks to establish a quantitative method which can estimate the holes and electrons ratio in the emission zones. We fabricated multilayered white organic light-emitting diodes (WOLEDs) with the device structure of ITO/NPB(80 nm)/MADN:BUBD-1(7%)(20 nm)/MADN:DCJTB(0.3%)(20 nm)/TPBi(X nm)/LiF(2 nm)/Al as a case study on the charge recombination distribution in the emissive layer. The result shows a trend in the charge recombination ratio depending on the electron transport layer thickness. We obtained an empirical relationship between electron transport layer thicknesses and emission ratio in EML. In addition, the electroluminescent spectra were analyzed by fitting a Gaussian distribution for the two emissive layers to calculate the intensity ratio of the energy transitions. The arrival time of hole and electrons from each electrode was determined using the thickness and mobility of TPBi as electron transport layer. From these initial results, we derived an empirical mechanism to meet with a linear relationship that can allow us to design custom- made WOLEDs. PMID- 29453364 TI - Biogeographical Differences in the Influence of Maternal Microbial Sources on the Early Successional Development of the Bovine Neonatal Gastrointestinal tract. AB - The impact of maternal microbial influences on the early choreography of the neonatal calf microbiome were investigated. Luminal content and mucosal scraping samples were collected from ten locations in the calf gastrointestinal tract (GIT) over the first 21 days of life, along with postpartum maternal colostrum, udder skin, and vaginal scrapings. Microbiota were found to vary by anatomical location, between the lumen and mucosa at each GIT location, and differentially enriched for maternal vaginal, skin, and colostral microbiota. Most calf sample sites exhibited a gradual increase in alpha-diversity over the 21 days beginning the first few days after birth. The relative abundance of Firmicutes was greater in the proximal GIT, while Bacteroidetes were greater in the distal GIT. Proteobacteria exhibited greater relative abundances in mucosal scrapings relative to luminal content. Forty-six percent of calf luminal microbes and 41% of mucosal microbes were observed in at-least one maternal source, with the majority being shared with microbes on the skin of the udder. The vaginal microbiota were found to harbor and uniquely share many common and well-described fibrolytic rumen bacteria, as well as methanogenic archaea, potentially indicating a role for the vagina in populating the developing rumen and reticulum with microbes important to the nutrition of the adult animal. PMID- 29453366 TI - Time-dependent Enhanced Corrosion of Ti6Al4V in the Presence of H2O2 and Albumin. AB - There is increasing concern regarding the biological consequences of metal release from implants. However, the mechanisms underpinning implant surface degradation, especially in the absence of wear, are often poorly understood. Here the synergistic effect of albumin and H2O2 on corrosion of Ti6Al4V in physiological saline is studied with electrochemical methods. It is found that albumin induces a time-dependent dissolution of Ti6Al4V in the presence of H2O2 in physiology saline. Potentiostatic polarisation measurements show that albumin supresses dissolution in the presence of H2O2 at short times (<24 h) but over longer time periods (120 h) it significantly accelerates corrosion, which is attributed to albumin-catalysed dissolution of the corrosion product layer resulting in formation of a thinner oxide film. Dissolution of Ti6Al4V in the presence of albumin and H2O2 in physiological saline is also found to be dependent on potential: the titanium ion release rate is found to be higher (0.57 ug/cm2) at a lower potential (90 mV), where the oxide capacitance and resistance inferred from Electrochemical Impedance Spectroscopy also suggests a less resistant oxide film. The study highlights the importance of using more realistic solutions, and considering behaviour over longer time periods when testing corrosion resistance of metallic biomaterials. PMID- 29453368 TI - Effects of timber harvesting on the genetic potential for carbon and nitrogen cycling in five North American forest ecozones. AB - Forest ecosystems are critical to global biogeochemical cycles but under pressure from harvesting and climate change. We investigated the effects of organic matter (OM) removal during forest harvesting on the genetic potential of soil communities for biomass decomposition and nitrogen cycling in five ecozones across North America. We analyzed 107 samples, representing four treatments with varied levels of OM removal, at Long-Term Soil Productivity Study sites. Samples were collected more than ten years after harvesting and replanting and were analyzed via shotgun metagenomics. High-quality short reads totaling 1.2 Tbp were compared to the Carbohydrate Active Enzyme (CAZy) database and a custom database of nitrogen cycle genes. Gene profile variation was mostly explained by ecozone and soil layer. Eleven CAZy and nine nitrogen cycle gene families were associated with particular soil layers across all ecozones. Treatment effects on gene profiles were mainly due to harvesting, and only rarely to the extent of OM removal. Harvesting generally decreased the relative abundance of CAZy genes while increasing that of nitrogen cycle genes, although these effects varied among ecozones. Our results suggest that ecozone-specific nutrient availability modulates the sensitivity of the carbon and nitrogen cycles to harvesting with possible consequences for long-term forest sustainability. PMID- 29453369 TI - Intratesticular injection followed by electroporation allows gene transfer in caprine spermatogenic cells. AB - The production of transgenic livestock is constrained due to the limited success of currently available methods for transgenesis. Testis mediated gene transfer (TMGT) is an emerging method that shows a high success rate in generating transgenic mice. In this study, we report a newly developed protocol for electroporation-aided TMGT to produce a transgenic goat. The injectable volume and concentration of the transgene were first standardized, and then electroporation conditions were optimized in vitro. In vivo experiments were performed by injecting a transgenic construct (pIRES2-EGFP; enhanced green fluorescent protein) into the testicular interstitium followed by electroporation. Immunohistochemistry, quantitative real-time PCR (qPCR) and western blotting analyses confirmed the successful transfer of the transgene into seminiferous tubules and testicular cells. Furthermore, chromosomal integration of the transgene and its expression in sperm were evaluated d60 and d120 post electroporation. Our protocol neither altered the seminal characteristics nor the fertilization capacity of the sperm cells. In vitro fertilization using transgenic sperm generated fluorescent embryos. Finally, natural mating of a pre founder buck produced a transgenic baby goat. The present study demonstrates the first successful report of an electroporation-aided TMGT method for gene transfer in goats. PMID- 29453370 TI - A multitarget approach to drug discovery inhibiting Mycobacterium tuberculosis PyrG and PanK. AB - Mycobacterium tuberculosis, the etiological agent of the infectious disease tuberculosis, kills approximately 1.5 million people annually, while the spread of multidrug-resistant strains is of great global concern. Thus, continuous efforts to identify new antitubercular drugs as well as novel targets are crucial. Recently, two prodrugs activated by the monooxygenase EthA, 7947882 and 7904688, which target the CTP synthetase PyrG, were identified and characterized. In this work, microbiological, biochemical, and in silico methodologies were used to demonstrate that both prodrugs possess a second target, the pantothenate kinase PanK. This enzyme is involved in coenzyme A biosynthesis, an essential pathway for M. tuberculosis growth. Moreover, compound 11426026, the active metabolite of 7947882, was demonstrated to directly inhibit PanK, as well. In an independent screen of a compound library against PyrG, two additional inhibitors were also found to be active against PanK. In conclusion, these direct PyrG and PanK inhibitors can be considered as leads for multitarget antitubercular drugs and these two enzymes could be employed as a "double-tool" in order to find additional hit compounds. PMID- 29453371 TI - Plasmonic Spherical Heterodimers: Reversal of Optical Binding Force Based on the Forced Breaking of Symmetry. AB - The stimulating connection between the reversal of near-field plasmonic binding force and the role of symmetry-breaking has not been investigated comprehensively in the literature. In this work, the symmetry of spherical plasmonic heterodimer setup is broken forcefully by shining the light from a specific side of the set up instead of impinging it from the top. We demonstrate that for the forced symmetry-broken spherical heterodimer-configurations: reversal of lateral and longitudinal near-field binding force follow completely distinct mechanisms. Interestingly, the reversal of longitudinal binding force can be easily controlled either by changing the direction of light propagation or by varying their relative orientation. This simple process of controlling binding force may open a novel generic way of optical manipulation even with the heterodimers of other shapes. Though it is commonly believed that the reversal of near-field plasmonic binding force should naturally occur for the presence of bonding and anti-bonding modes or at least for the Fano resonance (and plasmonic forces mostly arise from the surface force), our study based on Lorentz-force dynamics suggests notably opposite proposals for the aforementioned cases. Observations in this article can be very useful for improved sensors, particle clustering and aggregation. PMID- 29453372 TI - Enzyme mediated nanofibrillation of cellulose by the synergistic actions of an endoglucanase, lytic polysaccharide monooxygenase (LPMO) and xylanase. AB - Physiochemical methods have generally been used to "open-up" biomass substrates/pulps and have been the main method used to fibrillate cellulose. However, recent work has shown that canonical cellulase enzymes such as endoglucanases, in combination with "amorphogenesis inducing" proteins such as lytic polysaccharide monooxygenases (LPMO), swollenin and hemicellulases, are able to increase cellulose accessibility. In the work reported here different combinations of endoglucanase, LPMO and xylanase were applied to Kraft pulps to assess their potential to induce fibrillation at low enzyme loading over a short time period. Although gross fiber properties (fiber length, width and morphology) were relatively unchanged, over a short period of time, the intrinsic physicochemical characteristics of the pulp fibers (e.g. cellulose accessibility/DP/crystallinity/charge) were positively enhanced by the synergistic cooperation of the enzymes. LPMO addition resulted in the oxidative cleavage of the pulps, increasing the negative charge (~100 mmol kg-1) on the cellulose fibers. This improved cellulose nanofibrilliation while stabilizing the nanofibril suspension (zeta potential zeta = ~60 mV), without sacrificing nanocellulose thermostability. The combination of endoglucanase, LPMO and xylanases was shown to facilitate nanofibrillation, potentially reducing the need for mechanical refining while resulting in a pulp with a more uniform nanofibril composition. PMID- 29453373 TI - Dormancy release and germination of Taxus yunnanensis seeds during wet sand storage. AB - Dormancy is an innate constraint on germination that occurs across all life forms. In this study, we investigated the seed dormancy release and germination characters of Taxus yunnanensis by exploring the seed morphology, permeability, germination inhibitors, endogenous hormones, and embryo germination in vitro during wet sand storage. Our results showed that seeds and embryos grew to a critical size to germination and permeability increased with the extension of storage. Seed coat and kernel methanol extracts reduced Brassica campestris seed vigor index. The in vitro embryo germination rate increased by 12.20% after storage for 30-360 d, whereas seed germination occurred after 450 d. Gibberellic acid and zeatin riboside contents were relatively stable, whereas abscisic acid (ABA) content decreased; indole acetic acid (IAA) content and the IAA/ABA ratio showed increasing trends. These results indicate that ABA is the key inhibitor of germination in Taxus. The chemical(s) in seed coat and kernel cause the inhibition of seed germination. Taken together, Taxus seeds have morphophysiological dormancy, in which the embryos can continue to grow and hormone imbalance inhibits further development and germination. Further, seed dormancy is active even during the middle of storage and shows "double peaks" during the entire dormancy process. PMID- 29453374 TI - Cardiovascular and renal protective role of angiotensin blockade in hypertension with advanced CKD: a subgroup analysis of ATTEMPT-CVD randomized trial. AB - The ATTEMPT-CVD study was prospective randomized active-controlled trial and the main findings had been reported. According to baseline GFR and albuminuria categories, we divided the patients of the ATTEMPT-CVD study into 2 subgroups: (Group 1) the patients with at least one of eGFR of <45 ml/min per 1.73 m2 and UACR of >=300 mg/g creatinine, defined as G3b and/or A3; (Group 2) the patients except for Group 1, defined as the other patients. In patients with G3b and/or A3, the incidence of cardiovascular events was significantly less in ARB group than in non-ARB group (11 vs 22, respectively) (HR = 0.465: 95%CI = 0.224-0.965; P = 0.040). UACR was significantly less in ARB group than in non-ARB group during follow-up period in patients with G3b and/or A3 (P = 0.0003), while eGFR, plasma BNP levels, and blood pressure were comparable between ARB and non-ARB groups. Allocation to ARB therapy was a significant independent prognostic factor for cardiovascular events in patients with G3b and/or A3 (P = 0.0268). On the other hand, in the other patients, the occurrence of cardiovascular events was comparable between ARB and non-ARB groups. In patients with advanced CKD, ARB based therapy may confer greater benefit in prevention of cardiovascular events than non-ARB therapy. PMID- 29453375 TI - Self-supporting Co3O4/Graphene Hybrid Films as Binder-free Anode Materials for Lithium Ion Batteries. AB - A self-supporting Co3O4/graphene hybrid film has been constructed via vacuum filtration of Co(OH)2 nanosheet and graphene, followed by a two-step thermal treatment. Within the hybrid film, Co3O4 nanoparticles with size of 40~60 nm uniformly in-situ grew on the surface of graphene, forming a novel porous and interleaved structure with strong interactions between Co3O4 nanoparticles and graphene. Such fascinating microstructures can greatly facilitate interfacial electron transportation and accommodate the volume changes upon Li ions insertion and extraction. Consequently, the binder-less hybrid film demonstrated extremely high reversible capacity (1287.7 mAh g-1 at 0.2 A g-1), excellent cycling stability and rate capability (1110 and 800 mAh g-1 at 0.5 and 1.0 A g-1, respectively). PMID- 29453376 TI - High quality self-separated GaN crystal grown on a novel nanoporous template by HVPE. AB - In this study, a novel nanoporous template was obtained by a two-step etching process from MOCVD-GaN/Al2O3 (MGA) with electrochemical etching sequentially followed by chemical wet etching. The twice-etched MOCVD-GaN/Al2O3 (TEMGA) templates were utilized to grow GaN crystals by hydride vapor phase epitaxy (HVPE) method. The GaN crystals were separated spontaneously from the TEMGA template with the assistance of voids formed by the etched nanopores. Several techniques were utilized to characterize the quality of the free-standing GaN crystals obtained from the TEMGA template. Results showed that the quality of the as-obtained GaN crystals was improved obviously compared with those grown on the MGA. This convenient technique can be applied to grow high-quality free-standing GaN crystals. PMID- 29453377 TI - Optimized peptide based inhibitors targeting the dihydrofolate reductase pathway in cancer. AB - We report the first peptide based hDHFR inhibitors designed on the basis of structural analysis of dihydrofolate reductase (DHFR). A set of peptides were rationally designed and synthesized using solid phase peptide synthesis and characterized using nuclear magnetic resonance and enzyme immunoassays. The best candidate among them, a tetrapeptide, was chosen based on molecular mechanics calculations and evaluated in human lung adenocarcinoma cell line A549. It showed a significant reduction of cell proliferation and an IC50 of 82 uM was obtained. The interaction of the peptide with DHFR was supported by isothermal calorimetric experiments revealing a dissociation constant Kd of 0.7 uM and DeltaG of -34 +/- 1 kJ mol-1. Conjugation with carboxylated polystyrene nanoparticles improved further its growth inhibitory effects. Taken together, this opens up new avenues to design, develop and deliver biocompatible peptide based anti-cancer agents. PMID- 29453378 TI - Phenotypic plasticity vs. local adaptation in quantitative traits differences of Stipa grandis in semi-arid steppe, China. AB - Whether plants are able to adapt to environmental changes depends on their genetic characteristics and phenotypic plastic responses. We investigated the phenotypic responses of 7 populations of an important dominant species in semi arid steppe of China - Stipa grandis, and then distinguished which adaptive mechanism(s), phenotypic plasticity or local adaptation, was/were involved in this species to adapt to environmental changes. (1) All traits were significantly influenced by the interaction of population and growth condition and by population in each condition, and inter-population variability (CVinter) was larger in the field than in the common garden for 8/9 traits, indicating that both phenotypic plasticity and genetic differentiation controlled the phenotypic differences of S. grandis. (2) From a functional standpoint, the significant relationships between the values of traits in the common garden and the environmental variables in their original habitats couldn't support local habitat adaptation of these traits. (3) Low CVintra, low quantitative differentiation among populations (Q ST ), and low plasticity shown in the western populations indicated the very low adaptive potential of S. grandis to environmental changes. (4) From the original habitats to the common garden which is far away from S. grandis distribution region, positive phenotypic responses were found in several populations, indicating that some original habitats have become unfavorable for S. grandis.

PMID- 29453383 TI - Hyperbaric oxygen therapy is well tolerated and effective for ulcerative colitis patients hospitalized for moderate-severe flares: a phase 2A pilot multi-center, randomized, double-blind, sham-controlled trial. AB - BACKGROUND: Hyperbaric oxygen therapy (HBOT) markedly increases tissue oxygen delivery. Case series suggest it may have a potential therapeutic benefit in ulcerative colitis (UC). We investigated the therapeutic potential of HBOT as an adjunct to steroids for UC flares requiring hospitalization. METHODS: The study was terminated early due to poor recruitment with 18 of the planned 70 patients enrolled. UC patients hospitalized for moderate-severe flares (Mayo score >=6, endoscopic sub-score >=2) were block randomized to steroids + daily HBOT (n = 10) or steroids + daily sham hyperbaric air (n = 8). Patients were blinded to study assignment, and assessments were performed by a blinded gastroenterologist. Primary outcome was the clinical remission rate at study day 5 (partial Mayo score <=2 with no sub-score >1). Key secondary outcomes were: clinical response (reduction in partial Mayo score >=2, rectal bleeding sub-score of 0-1) and progression to second-line therapy (colectomy or biologic therapy) during the hospitalization. RESULTS: A significantly higher proportion of HBOT-treated patients achieved clinical remission at study day 5 and 10 (50 vs. 0%, p = 0.04). HBOT-treated patients less often required progression to second-line therapy during the hospitalization (10 vs. 63%, p = 0.04). The proportion requiring in hospital colectomy specifically as second-line therapy for medically refractory UC was lower in the HBOT group compared to sham (0 vs. 38%, p = 0.07). There were no serious adverse events. CONCLUSION: In this small, proof-of-concept, phase 2A trial, the use of HBOT as an adjunctive therapy to steroids for UC patients hospitalized for moderate-severe flares resulted in higher rates of clinical remission, and a reduction in rates of progression to second-line therapy during the hospitalization. Larger well-powered trials are needed, however, to provided definitive evidence of therapeutic benefit.

AB - OBJECTIVES: The impact of irritable bowel syndrome (IBS)-type symptoms on the natural history of inflammatory bowel disease (IBD) is uncertain. We aimed to address this in a longitudinal study of secondary care patients. METHODS: Longitudinal disease activity was defined by disease flare, escalation of medical therapy, hospitalization, or intestinal resection. The number of investigations performed and clinics attended determined healthcare utilization. Psychological well-being and quality of life were assessed using validated questionnaires. These outcomes were compared over a minimum period of 2 years between patients reporting IBS-type symptoms and patients with quiescent disease, occult inflammation, and active disease at baseline. RESULTS: In 360 IBD patients, there were no differences in longitudinal disease activity between patients with IBS type symptoms and patients with quiescent disease or occult inflammation. Disease flare and escalation of medical therapy was more common in patients with active disease than in patients with IBS-type symptoms (hazard ratio (HR) = 3.16; 95% confidence interval (CI) 1.93-5.19 and HR = 3.24; 95% CI 1.98-5.31, respectively). A greater number of investigations were performed in patients with IBS-type symptoms than quiescent disease (P = 0.008), but not compared with patients with occult inflammation or active disease. Anxiety, depression, and somatization scores at follow up were higher, and quality-of-life scores lower, in patients with IBS-type symptoms when compared with patients with quiescent disease, but were similar to patients with active disease. CONCLUSIONS: IBS-type symptoms in IBD were associated with increased healthcare utilization, psychological comorbidity, reduced quality of life, but not adverse disease activity outcomes during extended follow-up.

AB - We aimed to investigate the value of breast magnetic resonance (MR) imaging and positron emission tomography-computed tomography (PET/CT) in predicting advanced axillary lymph node (ALN) metastases (ypN2-3) after neoadjuvant chemotherapy (NAC) in invasive ductal carcinoma patients. A total of 108 patients with invasive ductal carcinoma underwent breast MR imaging and PET/CT both before and after NAC (termed initial staging and restaging, respectively). The number of positive ALNs and the short diameter (SD) of the largest ALN on breast MR imaging and maximal standardized uptake value (SUVmax) in the ALNs on PET/CT were evaluated. Odds ratio (OR) for prediction of advanced ALN metastases was calculated. The negative predictive value (NPV) of restaging imaging for exclusion of advanced ALN metastases was also calculated. Patients with advanced ALN metastases were more likely to have a higher number (>=2) of positive LNs (OR, 8.06; P = 0.015) on restaging MR imaging. No clinico-pathological factors were significantly associated with advanced ALN metastases. With restaging MR imaging, PET/CT, and MR imaging plus PET/CT, the NPV for excluding advanced ALN metastases was 97.3%, 94.4%, and 100.0%. A higher number of positive ALNs on restaging MR imaging was an independent predictor for advanced ALN metastases after NAC. PMID- 29453386 TI - Anti-fibrotic Effects of CXCR4-Targeting i-body AD-114 in Preclinical Models of Pulmonary Fibrosis. AB - Idiopathic pulmonary fibrosis (IPF) is a chronic fibrotic lung disease that is prevalent in individuals >50 years of age, with a median survival of 3-5 years and limited therapeutic options. The disease is characterized by collagen deposition and remodeling of the lung parenchyma in a process that is thought to be driven by collagen-expressing immune and structural cells. The G-protein coupled C-X-C chemokine receptor 4, CXCR4, is a candidate therapeutic target for IPF owing to its role in the recruitment of CXCR4+ fibrocytes from the bone marrow to fibrotic lung tissue and its increased expression levels by structural cells in fibrotic lung tissue. We have engineered a novel fully human single domain antibody "i-body" called AD-114 that binds with high affinity to human CXCR4. We demonstrate here that AD-114 inhibits invasive wound healing and collagen 1 secretion by human IPF fibroblasts but not non-diseased control lung fibroblasts. Furthermore, in a murine bleomycin model of pulmonary fibrosis, AD 114 reduced the accumulation of fibrocytes (CXCR4+/Col1+/CD45+) in fibrotic murine lungs and ameliorated the degree of lung injury. Collectively, these studies demonstrate that AD-114 holds promise as a new biological therapeutic for the treatment of IPF.

AB - Pervasive transcription of mammalian genomes leads to a previously underestimated level of complexity in gene regulatory networks. Recently, we have identified a new functional class of natural and synthetic antisense long non-coding RNAs (lncRNA) that increases translation of partially overlapping sense mRNAs. These molecules were named SINEUPs, as they require an embedded inverted SINE B2 element for their UP-regulation of translation. Mouse AS Uchl1 is the representative member of natural SINEUPs. It was originally discovered for its role in increasing translation of Uchl1 mRNA, a gene associated with neurodegenerative diseases. Here we present the secondary structure of the SINE B2 Transposable Element (TE) embedded in AS Uchl1. We find that specific structural regions, containing a short hairpin, are required for the ability of AS Uchl1 RNA to increase translation of its target mRNA. We also provide a high resolution structure of the relevant hairpin, based on NMR observables. Our results highlight the importance of structural determinants in embedded TEs for their activity as functional domains in lncRNAs. PMID- 29453388 TI - Identifying noncoding risk variants using disease-relevant gene regulatory networks. AB - Identifying noncoding risk variants remains a challenging task. Because noncoding variants exert their effects in the context of a gene regulatory network (GRN), we hypothesize that explicit use of disease-relevant GRNs can significantly improve the inference accuracy of noncoding risk variants. We describe Annotation of Regulatory Variants using Integrated Networks (ARVIN), a general computational framework for predicting causal noncoding variants. It employs a set of novel regulatory network-based features, combined with sequence-based features to infer noncoding risk variants. Using known causal variants in gene promoters and enhancers in a number of diseases, we show ARVIN outperforms state-of-the-art methods that use sequence-based features alone. Additional experimental validation using reporter assay further demonstrates the accuracy of ARVIN. Application of ARVIN to seven autoimmune diseases provides a holistic view of the gene subnetwork perturbed by the combinatorial action of the entire set of risk noncoding mutations. PMID- 29453389 TI - Toxicity Classification of Oxide Nanomaterials: Effects of Data Gap Filling and PChem Score-based Screening Approaches. AB - Development of nanotoxicity prediction models is becoming increasingly important in the risk assessment of engineered nanomaterials. However, it has significant obstacles caused by the wide heterogeneities of published literature in terms of data completeness and quality. Here, we performed a meta-analysis of 216 published articles on oxide nanoparticles using 14 attributes of physicochemical, toxicological and quantum-mechanical properties. Particularly, to improve completeness and quality of the extracted dataset, we adapted two preprocessing approaches: data gap-filling and physicochemical property based scoring. Performances of nano-SAR classification models revealed that the dataset with the highest score value resulted in the best predictivity with compromise in its applicability domain. The combination of physicochemical and toxicological attributes was proved to be more relevant to toxicity classification than quantum mechanical attributes. Overall, by adapting these two preprocessing methods, we demonstrated that meta-analysis of nanotoxicity literatures could provide an effective alternative for the risk assessment of engineered nanomaterials. PMID- 29453390 TI - Birds and beans: Comparing avian richness and endemism in arabica and robusta agroforests in India's Western Ghats. AB - Coffee is a major tropical commodity crop that can provide supplementary habitat for native wildlife. In Asia, coffee production is an increasingly important driver of landscape transformation and shifts between different coffee species is a major dimension of agroforestry trends. Yet few studies have compared the ecological impacts of conversion between different coffee species. We evaluated whether or not the two species of coffee grown globally-Coffea arabica and C. canephora (denoted "robusta")-had equivalent avian conservation value in the Western Ghats, India, where robusta production has become increasingly dominant. We found that habitat specialist and functional guild diversity was higher in arabica, and that arabica was more profitable. However, robusta farms generally supported the same or slightly higher abundances of habitat specialists and functional guilds, largely due to dense canopy and landscape-level forest cover. Farming practices, chiefly pesticide use, may affect the suitability of coffee agroforests as habitat for avian specialists, and at present, robusta farmers tended to use less pesticide. Given future projections for arabica to robusta conversion in tropical Asia, our study indicates that certification efforts should prioritize maintaining native canopy shade trees and forest cover to ensure that coffee landscapes can continue providing biodiversity benefits. PMID- 29453391 TI - Diffusion mechanism in the sodium-ion battery material sodium cobaltate. AB - High performance batteries based on the movement of Li ions in Li x CoO2 have made possible a revolution in mobile electronic technology, from laptops to mobile phones. However, the scarcity of Li and the demand for energy storage for renewables has led to intense interest in Na-ion batteries, including structurally-related Na x CoO2. Here we have determined the diffusion mechanism for Na0.8CoO2 using diffuse x-ray scattering, quasi-elastic neutron scattering and ab-initio molecular dynamics simulations, and we find that the sodium ordering provides diffusion pathways and governs the diffusion rate. Above T ~ 290 K the so-called partially disordered stripe superstructure provides channels for quasi-1D diffusion, and melting of the sodium ordering leads to 2D superionic diffusion above T ~ 370 K. We obtain quantitative agreement between our microscopic study of the hopping mechanism and bulk self-diffusion measurements. Our approach can be applied widely to other Na- or Li-ion battery materials. PMID- 29453392 TI - A novel flatworm-specific gene implicated in reproduction in Macrostomum lignano. AB - Free-living flatworms, such as the planarian Schmidtea mediterranea, are extensively used as model organisms to study stem cells and regeneration. The majority of flatworm studies so far focused on broadly conserved genes. However, investigating what makes these animals different is equally informative for understanding its biology and might have biomedical value. We re-analyzed the neoblast and germline transcriptional signatures of the flatworm M. lignano using an improved transcriptome assembly and show that germline-enriched genes have a high fraction of flatworm-specific genes. We further identified the Mlig-sperm1 gene as a member of a novel gene family conserved only in free-living flatworms and essential for producing healthy spermatozoa. In addition, we established a whole-animal electron microscopy atlas (nanotomy) to visualize the ultrastructure of the testes in wild type worms, but also as a reference platform for different ultrastructural studies in M. lignano. This work demonstrates that investigation of flatworm-specific genes is crucial for understanding flatworm biology and establishes a basis for such future research in M. lignano. PMID- 29453393 TI - Adherence to antiretroviral therapy and factors affecting low medication adherence among incident HIV-infected individuals during 2009-2016: A nationwide study. AB - For ideal clinical benefit, human immunodeficiency virus (HIV)-infected individuals should receive continuous medication. This is the first nationwide antiretroviral therapy (ART) adherence study in Asia, where medication monitoring at national level is systemically available. We estimated the ART adherence of incident HIV-infected individuals and investigated factors affecting low medication adherence using the national health insurance (NHI) claims data from 2007 to 2016. Medication possession ratio (MPR) was used to measure medication adherence and risk factors were identified by multivariable logistic regression analysis. Of the 8,501 newly diagnosed HIV-infected individuals during 2009-2016 with at least one ART prescription, 70.4% of HIV patients had adequate adherence to ART defined as MPR >=95%. Requiring prophylactic antibiotics, female gender, age of 0-19 and same or over 50 s compared to 30-39, and having a history of malignancy, lower socioeconomic status, not visiting tertiary hospital, and being diagnosed in the earlier years were risk factors for lower adherence (Odds ratio 1.7, 1.6, 1.6, 1.4, 1.6, 2.1, 1.2, and 1.6 to 3.8 respectively). Health authority should take into consideration of these modifiable and unmodifiable barriers to establish sustainable monitoring system at national level and to improve adherence. PMID- 29453394 TI - Experimental modelling of cardiac pressure overload hypertrophy: Modified technique for precise, reproducible, safe and easy aortic arch banding-debanding in mice. AB - Pressure overload left ventricular hypertrophy is a known precursor of heart failure with ominous prognosis. The development of experimental models that reproduce this phenomenon is instrumental for the advancement in our understanding of its pathophysiology. The gold standard of these models is the controlled constriction of the mid aortic arch in mice according to Rockman's technique (RT). We developed a modified technique that allows individualized and fully controlled constriction of the aorta, improves efficiency and generates a reproducible stenosis that is technically easy to perform and release. An algorithm calculates, based on the echocardiographic arch diameter, the intended perimeter at the constriction, and a suture is prepared with two knots separated accordingly. The aorta is encircled twice with the suture and the loop is closed with a microclip under both knots. We performed controlled aortic constriction with Rockman's and the double loop-clip (DLC) techniques in mice. DLC proved superiority in efficiency (mortality and invalid experiments) and more homogeneity of the results (transcoarctational gradients, LV mass, cardiomyocyte hypertrophy, gene expression) than RT. DLC technique optimizes animal use and generates a consistent and customized aortic constriction with homogeneous LV pressure overload morphofunctional, structural, and molecular features. PMID- 29453395 TI - The genes of the sulphoquinovose catabolism in Escherichia coli are also associated with a previously unknown pathway of lactose degradation. AB - Comparative genomics analysis of conserved gene cassettes demonstrated resemblance between a recently described cassette of genes involved in sulphoquinovose degradation in Escherichia coli K-12 MG1655 and a Bacilli cassette linked with lactose degradation. Six genes from both cassettes had similar functions related to carbohydrate metabolism, namely, hydrolase, aldolase, kinase, isomerase, transporter, and transcription factor. The Escherichia coli sulphoglycolysis cassette was thus predicted to be associated with lactose degradation. This prediction was confirmed experimentally: expression of genes coding for aldolase (yihT), isomerase (yihS), and kinase (yihV) was dramatically increased during growth on lactose. These genes were previously shown to be activated during growth on sulphoquinovose, so our observation may indicate multi-functional capabilities of the respective proteins. Transcription starts for yihT, yihV and yihW were mapped in silico, in vitro and in vivo. Out of three promoters for yihT, one was active only during growth on lactose. We further showed that switches in yihT transcription are controlled by YihW, a DeoR-family transcription factor in the Escherichia coli cassette. YihW acted as a carbon source-dependent dual regulator involved in sustaining the baseline growth in the absence of lac-operon, with function either complementary, or opposite to a global regulator of carbohydrate metabolism, cAMP CRP. PMID- 29453396 TI - Bone marrow lympho-myeloid malfunction in obesity requires precursor cell autonomous TLR4. AB - Obesity, a prevalent condition in adults and children, impairs bone marrow (BM) function. However, the underlying mechanisms are unclear. Here, we show that obese mice exhibit poor emergency immune responses in a toll-like receptor 4 (TLR4)-dependent manner. Canonical myeloid genes (Csf1r, Spi1, Runx1) are enhanced, and lymphoid genes (Flt3, Tcf3, Ebf1) are reduced. Using adoptive transfer and mixed BM chimera approaches we demonstrate that myeloid>lymphoid bias arises after 6 weeks of high-fat diet and depends on precursor cell autonomous TLR4. Further, lean mice exposed to the TLR4 ligand lipopolysaccharide (LPS) at doses similar to that detectable in obese serum recapitulates BM lympho myeloid alterations. Together, these results establish a mechanistic contribution of BM cell-intrinsic TLR4 to obesity-driven BM malfunction and demonstrate the importance of LPS. Our findings raises important questions about the impact of maternal obesity and endotoxemia to fetal hematopoiesis, as fetal immune precursors are also sensitive to TLR4 signals. PMID- 29453397 TI - Temperature Dependence of the Dielectric Function of Monolayer MoSe2. AB - The dielectric function [Formula: see text] of monolayer molybdenum diselenide (MoSe2) is obtained and analyzed at temperatures from 31 to 300 K and at energies from 0.74 to 6.42 eV. The sample is a large-area, partially discontinuous monolayer (submonolayer) film of MoSe2 grown on a sapphire substrate by selenization of pulsed laser deposited MoO3 film. Morphological and optical characterizations verified the excellent quality of the film. The MoSe2 data were analyzed using the effective medium approximation, which treats the film and bare substrate regions as a single layer. Second derivatives of epsilon with respect to energy were numerically calculated and analyzed with standard lineshapes to extract accurate critical-point (CP) energies. We find only 6 CPs for monolayer MoSe2 at room temperature. At cryogenic temperatures 6 additional structures are resolved. The separations in the B- and C-excitonic peaks are also observed. All structures blue-shift and sharpen with decreasing temperature as a result of the reducing lattice constant and electron-phonon interactions. The temperature dependences of the CP energies were determined by fitting the data to the phenomenological expression that contains the Bose-Einstein statistical factor and the temperature coefficient. PMID- 29453398 TI - Host defense against oral microbiota by bone-damaging T cells. AB - The immune system evolved to efficiently eradicate invading bacteria and terminate inflammation through balancing inflammatory and regulatory T-cell responses. In autoimmune arthritis, pathogenic TH17 cells induce bone destruction and autoimmune inflammation. However, whether a beneficial function of T-cell induced bone damage exists is unclear. Here, we show that bone-damaging T cells have a critical function in the eradication of bacteria in a mouse model of periodontitis, which is the most common infectious disease. Bacterial invasion leads to the generation of specialized TH17 cells that protect against bacteria by evoking mucosal immune responses as well as inducing bone damage, the latter of which also inhibits infection by removing the tooth. Thus, bone-damaging T cells, which may have developed to stop local infection by inducing tooth loss, function as a double-edged sword by protecting against pathogens while also inducing skeletal tissue degradation. PMID- 29453400 TI - A survey of metastasis suppressors in Metazoa. AB - Metastasis suppressors are genes/proteins involved in regulation of one or more steps of the metastatic cascade while having little or no effect on tumor growth. The list of putative metastasis suppressors is constantly increasing although thorough understanding of their biochemical mechanism(s) and evolutionary history is still lacking. Little is known about tumor-related genes in invertebrates, especially non-bilaterians and unicellular relatives of animals. However, in the last few years we have been witnessing a growing interest in this subject since it has been shown that many disease-related genes are already present in simple non-bilateral animals and even in their unicellular relatives. Studying human diseases using simpler organisms that may better represent the ancestral conditions in which the specific disease-related genes appeared could provide better understanding of how those genes function. This review represents a compilation of published literature and our bioinformatics analysis to gain a general insight into the evolutionary history of metastasis-suppressor genes in animals (Metazoa). Our survey suggests that metastasis-suppressor genes emerged in three different periods in the evolution of Metazoa: before the origin of metazoans, with the emergence of first animals and at the origin of vertebrates. PMID- 29453399 TI - Association of Sleep and Circadian Activity Rhythm with Emotional Face Processing among 12-month-old Infants. AB - Sleep and circadian rhythmicity both play an important role in human's cognitive functioning, yet the way in which early development of sleep and circadian rhythm affects cognitive processes and social learning in infants remains less understood. We examined the association of sleep and circadian activity rhythm (CAR) with face and emotional information processing in 12-month old infants. Face processing was measured by eye tracking, whereby infants' scanning patterns and pupil dilations were calculated when they were presented with neutral, pleasant and unpleasant faces. Infants with better sleep quality (i.e., less waking after sleep onset) and lower sleep-wake pattern variability (i.e., higher inter-daily stability) exhibited a higher eyes over mouth fixation ratio (EMR). Infants with longer total sleep time showed larger pupil diameter changes in response to emotional facial expressions, more closely resembling the responses of adults. Our findings suggest the role of sleep and circadian rhythm in waking cognition and have implications for understanding the early development of social learning in young children. PMID- 29453401 TI - Endothelial smoothened-dependent hedgehog signaling is not required for sonic hedgehog induced angiogenesis or ischemic tissue repair. AB - Sonic Hedgehog (Shh) signaling induces neovascularization and angiogenesis. It is not known whether the hedgehog signaling pathway in endothelial cells is essential to angiogenesis. Smoothened (Smo) transduces hedgehog signaling across the cell membrane. This study assessed whether endothelial Smoothened-dependent Shh signaling is required for Shh-mediated angiogenesis and ischemic tissue repair. Endothelial-specific smoothened knockout mice, eSmoNull were created using Cre-lox recombination system. eSmoNull mice had no observable phenotype at baseline and showed normal cardiac function. Smoothened in CD31+ cells isolated from eSmoNull hearts was significantly reduced compared to CD31+ cells from eSmoWT littermate control hearts. Fluorescence immunostaining of eSmoNull heart sections showed Smo expression in endothelial cells was abolished. The hind-limb ischemia (HLI) model was used to assess the response to ischemic injury. Perfusion ratio, limb motor function, and limb necrosis were not significantly different after HLI between eSmoNull mice and eSmoWT. Capillary densities in the ischemic limb in eSmoNull mice were also similar to eSmoWT at 4 weeks after HLI. Next, response to exogenous Shh was assessed in the corneal angiogenesis model. There was no significant difference in corneal angiogenesis induced by administration of Shh pellets between eSmoWT and eSmoNull mice. Furthermore, in vitro experiments demonstrated that direct Shh had limited effects on endothelial cell proliferation and migration. However, conditioned media from Shh-treated fibroblasts had a more potent effect on endothelial cell proliferation and migration than non-treated conditioned media. Furthermore, Shh treatment of fibroblasts dramatically stimulated angiogenic growth factor expression, including PDGF-B, VEGF-A, HGF and IGF. PDGF-B was the most upregulated and may contribute to the large neo-vessels associated with Shh-induced angiogenesis. Taken together, these data demonstrate that Shh signaling via Smoothened in endothelial cells is not required for angiogenesis and ischemic tissue repair. Shh signaling via stromal cells likely mediates its angiogenic effects. PMID- 29453402 TI - A soft lithographic approach to fabricate InAs nanowire field-effect transistors. AB - The epitaxial layer transfer process was previously introduced to integrate high quality and ultrathin III-V compound semiconductor layers on any substrate. However, this technique has limitation for fabrication of sub-micron nanoribbons due to the diffraction limit of photolithography. In order to overcome this limitation and scale down its width to sub-50 nm, we need either a costly short wavelength lithography system or a non-optical patterning method. In this work, high-quality III-V compound semiconductor nanowires were fabricated and integrated onto a Si/SiO2 substrate by a soft-lithography top-down approach and an epitaxial layer transfer process, using MBE-grown ultrathin InAs as a source wafer. The width of the InAs nanowires was controlled using solvent-assisted nanoscale embossing (SANE), descumming, and etching processes. By optimizing these processes, NWs with a width less than 50 nm were readily obtained. The InAs NWFETs prepared by our method demonstrate peak electron mobility of ~1600 cm2/Vs, indicating negligible material degradation during the SANE process. PMID- 29453403 TI - Tailoring of magnetoimpedance effect and magnetic softness of Fe-rich glass coated microwires by stress- annealing. AB - There is a pressing need for improving of the high-frequency magneto-impedance effect of cost-effective soft magnetic materials for use in high-performance sensing devices. The impact of the stress-annealing on magnetic properties and high frequency impedance of Fe-rich glass-coated microwires was studied. Hysteresis loops of Fe-rich microwires have been considerably affected by stress- annealing. In stress-annealed Fe- rich microwire we obtained drastic decreasing of coercivity and change of character of hysteresis loop from rectangular to linear. By controlling stress-annealing conditions (temperature and time) we achieved drastic increasing (by order of magnitude) of giant magnetoimpedance ratio. Coercivity, remanent magnetization, diagonal and of-diagonal magnetoimpedance effect of Fe-rich microwires can be tuned by stress-annealing conditions: annealing temperature and time. Observed experimental results are discussed considering relaxation of internal stresses, compressive "back stresses" arising after stress annealing and topological short range ordering. PMID- 29453404 TI - PREP1 tumor suppressor protects the late-replicating DNA by controlling its replication timing and symmetry. AB - The synthesis of middle-to-late-replicating DNA can be affected independently of the rest of the genome by down-regulating the tumor suppressor PREP1 (PKNOX1). Indeed, DNA combing shows that PREP1 down-regulation affects DNA replication rate, increases the number of simultaneously firing origins and the asymmetry of DNA replication, leading to DNA damage. Genome-wide analysis of replication timing by Repli-seq shows that, upon PREP1 down-regulation, 25% of the genome is replicated earlier in the S-phase. The targeted DNA sequences correspond to Lamin Associated Domains (LADs), and include late-replicating (LRRs) and temporal transition regions (TTRs). Notably, the distribution of PREP1 DNA binding sites and of its target genes indicates that DNA replication defects are independent of the overall PREP1 transcriptional activity. Finally, PREP1 down-regulation causes a substantial decrease in Lamin B1 levels. This suggests that DNA is released from the nuclear lamina earlier than in the control cells and is available for replication, thus explaining timing defects and DNA damage.This is the first evidence that the replication timing of a specific fraction of the human genome is affected by PREP1 tumor suppressor. This previously unknown function might significantly contribute to the genomic instability observed in human tumors. PMID- 29453405 TI - Widespread use of incorrect PCR ramp rate negatively impacts multidrug-resistant tuberculosis diagnosis (MTBDRplus). AB - The scale-up of rapid drug resistance testing for TB is a global priority. MTBDRplus is a WHO-endorsed multidrug-resistant (MDR)-TB PCR assay with suboptimal sensitivities and high indeterminate rates on smear-negative specimens. We hypothesised that widespread use of incorrect thermocycler ramp rate (speed of temperature change between cycles) impacts performance. A global sample of 72 laboratories was surveyed. We tested 107 sputa from Xpert MTB/RIF positive patients and, separately, dilution series of bacilli, both at the manufacturer-recommended ramp rate (2.2 degrees C/s) and the most frequently reported incorrect ramp rate (4.0 degrees C/s). Mycobacterium tuberculosis complex DNA (TUB-band)-detection, indeterminate results, accuracy, and inter reader variability (dilution series only) were compared. 32 respondents did a median (IQR) of 41 (20-150) assays monthly. 78% used an incorrect ramp rate. On smear-negative sputa, 2.2 degrees C/s vs. 4.0 degrees C/s improved TUB-band positivity (42/55 vs. 32/55; p = 0.042) and indeterminate rates (1/42 vs. 5/32; p = 0.039). The actionable results (not TUB-negative or indeterminate; 41/55 vs. 28/55) hence improved by 21% (95% CI: 9-35%). Widespread use of incorrect ramp rate contributes to suboptimal MTBDRplus performance on smear-negative specimens and hence limits clinical utility. The number of diagnoses (and thus the number of smear-negative patients in whom DST is possible) will improve substantially after ramp rate correction. PMID- 29453406 TI - CRISPR-Cas9, a tool to efficiently increase the development of recombinant African swine fever viruses. AB - African swine fever virus (ASFV) causes a highly contagious disease called African swine fever. This disease is often lethal for domestic pigs, causing extensive losses for the swine industry. ASFV is a large and complex double stranded DNA virus. Currently there is no commercially available treatment or vaccine to prevent this devastating disease. Development of recombinant ASFV for producing live-attenuated vaccines or studying the involvement of specific genes in virus virulence has relied on the relatively rare event of homologous recombination in primary swine macrophages, causing difficulty to purify the recombinant virus from the wild-type parental ASFV. Here we present the use of the CRISPR-Cas9 gene editing system as a more robust and efficient system to produce recombinant ASFVs. Using CRISPR-Cas9 a recombinant virus was efficiently developed by deleting the non-essential gene 8-DR from the genome of the highly virulent field strain Georgia07 using swine macrophages as cell substrate. PMID- 29453407 TI - Neovasculature can be induced by patching an arterial graft into a vein: A novel in vivo model of spontaneous arteriovenous fistula formation. AB - Arteriovenous malformations consist of tangles of arteries and veins that are often connected by a fistula. The causes and mechanisms of these clinical entities are not fully understood. We discovered that suturing an arterial patch into the common jugular vein of rabbits led to spontaneous neovascularization, the formation of an arteriovenous fistula and the development of an arteriovenous shunt. An arterial patch excised from the common carotid artery was sutured into the common jugular vein. Within a month, a dense nidus-like neovasculature formed around the patch. Angiography and pulse-oximeter analyses showed that the blood flowing into the neovasculature was arterial blood. This indicated that an arteriovenous shunt had formed. Fluorescence in situ hybridization with a Y chromosome probe in female rabbits that received an arterial patch from male rabbits showed that the vessels close to the graft bore the Y chromosome, whereas the vessels further away did not. Enzyme-linked immunosorbent assays and cDNA microarray analysis showed that multiple angiogenic factors were upregulated after patch transplantation. This is the first in vivo model of spontaneous arteriovenous fistula formation. Further research on these differences may help to improve understanding of human vascular anomaly diseases and the basic principles underlying vasculogenesis and/or angiogenesis. PMID- 29453408 TI - Biosignals reflect pair-dynamics in collaborative work: EDA and ECG study of pair programming in a classroom environment. AB - Collaboration is a complex phenomenon, where intersubjective dynamics can greatly affect the productive outcome. Evaluation of collaboration is thus of great interest, and can potentially help achieve better outcomes and performance. However, quantitative measurement of collaboration is difficult, because much of the interaction occurs in the intersubjective space between collaborators. Manual observation and/or self-reports are subjective, laborious, and have a poor temporal resolution. The problem is compounded in natural settings where task activity and response-compliance cannot be controlled. Physiological signals provide an objective mean to quantify intersubjective rapport (as synchrony), but require novel methods to support broad deployment outside the lab. We studied 28 student dyads during a self-directed classroom pair-programming exercise. Sympathetic and parasympathetic nervous system activation was measured during task performance using electrodermal activity and electrocardiography. Results suggest that (a) we can isolate cognitive processes (mental workload) from confounding environmental effects, and (b) electrodermal signals show role specific but correlated affective response profiles. We demonstrate the potential for social physiological compliance to quantify pair-work in natural settings, with no experimental manipulation of participants required. Our objective approach has a high temporal resolution, is scalable, non-intrusive, and robust. PMID- 29453409 TI - A Potential Prognostic Long Noncoding RNA Signature to Predict Recurrence among ER-positive Breast Cancer Patients Treated with Tamoxifen. AB - Limited predictable long noncoding RNA (lncRNA) signature was reported in tamoxifen resistance among estrogen receptor (ER)-positive breast cancer (BC) patients. The aim of this study was to identify and assess prognostic lncRNA signature to predict recurrence among ER-positive BC patients treated with tamoxifen. Cohorts from Gene Expression Omnibus (GEO) (n = 298) and The Cancer Genome Atlas (TCGA) (n = 160) were defined as training and validation cohort, respectively. BC relapse associated lnRNAs was identify within training cohort, and the predictable value of recurrence was assessed in both cohorts. A total of 11lncRNAs were recognized to be associated with relapse free survival (RFS) of ER positive BC patients receiving tamoxifen, who were divided into low-risk and high risk group on basis of relapse risk scores (RRS). Multivariate cox regression analyses revealed that the RRS is an independent prognostic biomarker in the prediction of ER-positive BC patients' survival. GSEA indicated that high-risk group was associated with several signaling pathways in processing of BC recurrence and metastasis such as PI3K-Akt and Wnt signaling. Our 11-lncRNA based classifier is a reliable prognostic and predictive tool for disease relapse in BC patients receiving tamoxifen. PMID- 29453410 TI - Molecular characterization of colorectal adenomas with and without malignancy reveals distinguishing genome, transcriptome and methylome alterations. AB - The majority of colorectal cancer (CRC) arises from precursor lesions known as polyps. The molecular determinants that distinguish benign from malignant polyps remain unclear. To molecularly characterize polyps, we utilized Cancer Adjacent Polyp (CAP) and Cancer Free Polyp (CFP) patients. CAPs had tissues from the residual polyp of origin and contiguous cancer; CFPs had polyp tissues matched to CAPs based on polyp size, histology and dysplasia. To determine whether molecular features distinguish CAPs and CFPs, we conducted Whole Genome Sequencing, RNA seq, and RRBS on over 90 tissues from 31 patients. CAPs had significantly more mutations, altered expression and hypermethylation compared to CFPs. APC was significantly mutated in both polyp groups, but mutations in TP53, FBXW7, PIK3CA, KIAA1804 and SMAD2 were exclusive to CAPs. We found significant expression changes between CAPs and CFPs in GREM1, IGF2, CTGF, and PLAU, and both expression and methylation alterations in FES and HES1. Integrative analyses revealed 124 genes with alterations in at least two platforms, and ERBB3 and E2F8 showed aberrations specific to CAPs across all platforms. These findings provide a resource of molecular distinctions between polyps with and without cancer, which have the potential to enhance the diagnosis, risk assessment and management of polyps. PMID- 29453411 TI - The impact of a helminth-modified microbiome on host immunity. AB - Intestinal helminths have well-characterized modulatory effects on mammalian immune pathways. Ongoing helminth infection has been associated with both the suppression of allergies and an altered susceptibility to microbial infections. Enteric helminths share a niche with the intestinal microbiota, and the presence of helminths alters the microbiota composition and the metabolic signature of the host. Recent studies have demonstrated that the helminth-modified intestinal microbiome has the capacity to modify host immune responses even in the absence of live helminth infection. This article discusses the mechanisms by which helminths modify the intestinal microbiome of mammals, and reviews the evidence for a helminth-modified microbiome directly influencing host immunity during infectious and inflammatory diseases. Understanding the multifaceted mechanisms that underpin helminth immunomodulation will pave the way for novel therapies to combat infectious and inflammatory diseases. PMID- 29453412 TI - Pulmonary antigen encounter regulates the establishment of tissue-resident CD8 memory T cells in the lung airways and parenchyma. AB - Resident memory CD8 T (TRM) cells in the lung parenchyma (LP) and airways provide heterologous protection against influenza virus challenge. However, scant knowledge exists regarding factors necessary to establish and maintain lung CD8 TRM. Here we demonstrate that, in contrast to mechanisms described for other tissues, airway, and LP CD8 TRM establishment requires cognate antigen recognition in the lung. Systemic effector CD8 T cells could be transiently pulled into the lung in response to localized inflammation, however these effector cells failed to establish tissue residency unless antigen was present in the pulmonary environment. The interaction of effector CD8 T cells with cognate antigen in the lung resulted in increased and prolonged expression of the tissue retention markers CD69 and CD103, and increased expression of the adhesion molecule VLA-1. The inability of localized inflammation alone to establish lung TRM resulted in decreased viral clearance and increased mortality following heterosubtypic influenza challenge, despite equal numbers of circulating memory CD8 T cells. These findings demonstrate that pulmonary antigen encounter is required for the establishment of lung CD8 TRM and may inform future vaccine strategies to generate robust cellular immunity against respiratory pathogens. PMID- 29453413 TI - Depression and obesity: evidence of shared biological mechanisms. AB - Depression and obesity are common conditions with major public health implications that tend to co-occur within individuals. The relationship between these conditions is bidirectional: the presence of one increases the risk for developing the other. It has thus become crucial to gain a better understanding of the mechanisms responsible for the intertwined downward physiological spirals associated with both conditions. The present review focuses specifically on shared biological pathways that may mechanistically explain the depression obesity link, including genetics, alterations in systems involved in homeostatic adjustments (HPA axis, immuno-inflammatory activation, neuroendocrine regulators of energy metabolism including leptin and insulin, and microbiome) and brain circuitries integrating homeostatic and mood regulatory responses. Furthermore, the review addresses interventional opportunities and questions to be answered by future research that will enable a comprehensive characterization and targeting of the biological links between depression and obesity. PMID- 29453414 TI - Chemisorption of polysulfides through redox reactions with organic molecules for lithium-sulfur batteries. AB - Lithium-sulfur battery possesses high energy density but suffers from severe capacity fading due to the dissolution of lithium polysulfides. Novel design and mechanisms to encapsulate lithium polysulfides are greatly desired by high performance lithium-sulfur batteries towards practical applications. Herein, we report a strategy of utilizing anthraquinone, a natural abundant organic molecule, to suppress dissolution and diffusion of polysulfides species through redox reactions during cycling. The keto groups of anthraquinone play a critical role in forming strong Lewis acid-based chemical bonding. This mechanism leads to a long cycling stability of sulfur-based electrodes. With a high sulfur content of ~73%, a low capacity decay of 0.019% per cycle for 300 cycles and retention of 81.7% over 500 cycles at 0.5 C rate can be achieved. This finding and understanding paves an alternative avenue for the future design of sulfur-based cathodes toward the practical application of lithium-sulfur batteries. PMID- 29453415 TI - ERLIN1 mutations cause teenage-onset slowly progressive ALS in a large Turkish pedigree. AB - Amyotrophic lateral sclerosis (ALS) is a late-onset motor neuron disease with mostly dominant inheritance and a life expectancy of 2-5 years; however, a quite common occurrence of atypical forms of the disease, due to recessive inheritance, has become evident with the use of NGS technologies. In this paper, we describe a family with close consanguinity for at least four generations, suffering from a slowly progressive form of ALS. Spastic walking is observed since teenage years, while bulbar symptoms start much later, at the fifth or sixth decade of life. Patients usually die because of respiratory failure. Using whole-exome sequencing, we identified a novel homozygous p.(Val94Ala) (c.281T>C) (NG_052910.1) (NM_006459) variation in the endoplasmic reticulum lipid raft associated protein 1 (ERLIN1) gene, which segregates with the disease in the family. Here we suggest that ERLIN1 variants, previously shown in juvenile hereditary spastic paraplegia cases, may also be the cause of a slowly progressive early-onset ALS, starting with upper motor neuron features and developing into classical ALS with the addition of lower motor neuron dysfunction. We also demonstrate that ATP-binding cassette subfamily C member 2 (ABCC2) gene, responsible for hyperbilirubinemia, is linked to ERLIN1. PMID- 29453416 TI - Homozygous deletion in MYL9 expands the molecular basis of megacystis-microcolon intestinal hypoperistalsis syndrome. AB - Megacystis-microcolon-intestinal hypoperistalsis syndrome (MMIHS) is a severe disease characterized by functional obstruction in the urinary and gastrointestinal tract. The molecular basis of this condition started to be defined recently, and the genes related to the syndrome (ACTG2-heterozygous variant in sporadic cases; and MYH11 (myosin heavy chain 11), LMOD1 (leiomodin 1) and MYLK (myosin light chain (MLC) kinase)-autosomal recessive inheritance), encode proteins involved in the smooth muscle contraction, supporting a myopathic basis for the disease. In the present article, we described a family with two affected siblings with MMIHS born to consanguineous parents and the molecular investigation performed to define the genetic etiology. Previous whole exome sequencing of the affected child and parents did not identify a candidate gene for the disease in this family, but now we present a reanalysis of the data that led to the identification of a homozygous deletion encompassing the last exon of MYL9 (myosin regulatory light chain 9) in the affected individual. MYL9 gene encodes a regulatory myosin MLC and the phosphorylation of this protein is a crucial step in the contraction process of smooth muscle cell. Despite the absence of human or animal phenotype related to MYL9, a cause-effect relationship between MYL9 and the MMIHS seems biologically plausible. The present study reveals a strong candidate gene for autosomal recessive forms of MMIHS, expanding the molecular basis of this disease and reinforces the myopathic basis of this condition. PMID- 29453417 TI - Exome sequencing has higher diagnostic yield compared to simulated disease specific panels in children with suspected monogenic disorders. AB - As test costs decline, whole-exome sequencing (WES) has become increasingly used for clinical diagnosis, and now represents the primary alternative to gene panel testing for patients with a suspected genetic disorder. We sought to compare the diagnostic yield of singleton-WES with simulated application of commercial gene panels in children suspected of having a genetically heterogeneous condition. Recruitment, singleton-WES and phenotype-driven variant analysis was completed for 145 paediatric patients. At recruitment, clinicians were required to propose commercial gene panel tests as an alternative to WES and nominate a phenotype driven candidate gene list. In WES-diagnosed children, three commercial options for each proposed panel were identified and evaluated for hypothetical diagnostic yield assuming 100% analytical sensitivity and specificity. We compared the price of WES with the least costly panel in WES-diagnosed children. In WES-undiagnosed children, we evaluated the exonic coverage of their phenotype-driven gene list using aggregate data. WES diagnoses were made in genes not included in at least one-of-three commercial panels in 42% of cases. Had a panel been selected instead, 23% of WES-diagnosed children would not have been diagnosed. In 26% of cases, the least costly panel option would have been more expensive than WES. Evaluation of WES coverage found that at the most stringent level of 20* coverage, the likelihood of missing a clinically relevant variant in a candidate gene list was maximally 8%. The broader coverage of WES makes it a superior alternative to gene panel testing at similar financial cost for children with suspected complex monogenic phenotypes. PMID- 29453419 TI - A randomized controlled study of a consent intervention for participating in an NIH genome sequencing study. AB - To make an informed choice to participate in a genome sequencing study that may yield primary and secondary findings, one understands relevant information in the context of personal values. Consent forms to enroll in a sequencing study can be long and complex. The efficacy of the professional encounter to consider the information contained in the consent form and make an informed choice is unknown. Women diagnosed with primary ovarian insufficiency and eligible for a sequencing study were randomized to participate in one of two encounters with a genetic counselor: a consent intervention using a lower literacy, less dense form or a standard consent encounter. Data were complete for 188 of 225 participants. The average time was 32 min for the intervention and 34 min for the standard, with the intervention encounter generating more questions from participants. At six weeks following consent, no differences were found between the two groups in primary outcomes: 'sequencing benefits' knowledge (d = 0.12, 95%CI: 0.03,0.27), 'sequencing limitations' knowledge (d = 0.04, 95%CI: -0.13,0.21), expected personal benefits (d = -0.01, 95%CI: -0.26,0.23), and decisional conflict (d = 0.04, 95%CI: -0.14,0.21). Although intentions to learn secondary variants were high, only 60% (113) of participants made an informed choice as defined by the multi-dimensional model of informed choice. We found that a modified consent intervention was as effective as a standard encounter and led to more interaction. Our data suggest that making decisions to receive secondary findings may be particularly challenging and in need of further investigation to achieve informed choice. PMID- 29453418 TI - Periodic reanalysis of whole-genome sequencing data enhances the diagnostic advantage over standard clinical genetic testing. AB - Whole-genome sequencing (WGS) as a first-tier diagnostic test could transform medical genetic assessments, but there are limited data regarding its clinical use. We previously showed that WGS could feasibly be deployed as a single molecular test capable of a higher diagnostic rate than current practices, in a prospectively recruited cohort of 100 children meeting criteria for chromosomal microarray analysis. In this study, we report on the added diagnostic yield with re-annotation and reanalysis of these WGS data ~2 years later. Explanatory variants have been discovered in seven (10.9%) of 64 previously undiagnosed cases, in emerging disease genes like HMGA2. No new genetic diagnoses were made by any other method in the interval period as part of ongoing clinical care. The results increase the cumulative diagnostic yield of WGS in the study cohort to 41%. This represents a greater than 5-fold increase over the chromosomal microarrays, and a greater than 3-fold increase over all the clinical genetic testing ordered in practice. These findings highlight periodic reanalysis as yet another advantage of genomic sequencing in heterogeneous disorders. We recommend reanalysis of an individual's genome-wide sequencing data every 1-2 years until diagnosis, or sooner if their phenotype evolves. PMID- 29453421 TI - Minimum energy control for complex networks. AB - The aim of this paper is to shed light on the problem of controlling a complex network with minimal control energy. We show first that the control energy depends on the time constant of the modes of the network, and that the closer the eigenvalues are to the imaginary axis of the complex plane, the less energy is required for complete controllability. In the limit case of networks having all purely imaginary eigenvalues (e.g. networks of coupled harmonic oscillators), several constructive algorithms for minimum control energy driver node selection are developed. A general heuristic principle valid for any directed network is also proposed: the overall cost of controlling a network is reduced when the controls are concentrated on the nodes with highest ratio of weighted outdegree vs indegree. PMID- 29453420 TI - A multiplex serologic platform for diagnosis of tick-borne diseases. AB - Tick-borne diseases are the most common vector-borne diseases in the United States, with serology being the primary method of diagnosis. We developed the first multiplex, array-based assay for serodiagnosis of tick-borne diseases called the TBD-Serochip. The TBD-Serochip was designed to discriminate antibody responses to 8 major tick-borne pathogens present in the United States, including Anaplasma phagocytophilum, Babesia microti, Borrelia burgdorferi, Borrelia miyamotoi, Ehrlichia chaffeensis, Rickettsia rickettsii, Heartland virus and Powassan virus. Each assay contains approximately 170,000 12-mer linear peptides that tile along the protein sequence of the major antigens from each agent with 11 amino acid overlap. This permits accurate identification of a wide range of specific immunodominant IgG and IgM epitopes that can then be used to enhance diagnostic accuracy and integrate differential diagnosis into a single assay. To test the performance of the TBD-Serochip, we examined sera from patients with confirmed Lyme disease, babesiosis, anaplasmosis, and Powassan virus disease. We identified a wide range of specific discriminatory epitopes that facilitated accurate diagnosis of each disease. We also identified previously undiagnosed infections. Our results indicate that the TBD-Serochip is a promising tool for a differential diagnosis not available with currently employed serologic assays for TBDs. PMID- 29453422 TI - Operando characterization of cathodic reactions in a liquid-state lithium-oxygen micro-battery by scanning transmission electron microscopy. AB - Rechargeable non-aqueous lithium-oxygen batteries with a large theoretical capacity are emerging as a high-energy electrochemical device for sustainable energy strategy. Despite many efforts made to understand the fundamental Li-O2 electrochemistry, the kinetic process of cathodic reactions, associated with the formation and decomposition of a solid Li2O2 phase during charging and discharging, remains debate. Here we report direct visualization of the charge/discharge reactions on a gold cathode in a non-aqueous lithium-oxygen micro-battery using liquid-cell aberration-corrected scanning transmission electron microscopy (STEM) combining with synchronized electrochemical measurements. The real-time and real-space characterization by time-resolved STEM reveals the electrochemical correspondence of discharge/charge overpotentials to the nucleation, growth and decomposition of Li2O2 at a constant current density. The nano-scale operando observations would enrich our knowledge on the underlying reaction mechanisms of lithium-oxygen batteries during round-trip discharging and charging and shed lights on the strategies in improving the performances of lithium-oxygen batteries by tailoring the cathodic reactions. PMID- 29453423 TI - Unexpected mixed-mode transmission and moderate genetic regulation of Symbiodinium communities in a brooding coral. AB - Determining the extent to which Symbiodinium communities in corals are inherited versus environmentally acquired is fundamental to understanding coral resilience and to predicting coral responses to stressors like warming oceans that disrupt this critical endosymbiosis. We examined the fidelity with which Symbiodinium communities in the brooding coral Seriatopora hystrix are vertically transmitted and the extent to which communities are genetically regulated, by genotyping the symbiont communities within 60 larvae and their parents (9 maternal and 45 paternal colonies) using high-throughput sequencing of the ITS2 locus. Unexpectedly, Symbiodinium communities associated with brooded larvae were distinct from those within parent colonies, including the presence of types not detected in adults. Bayesian heritability (h2) analysis revealed that 33% of variability in larval Symbiodinium communities was genetically controlled. Results highlight flexibility in the establishment of larval symbiont communities and demonstrate that symbiont transmission is not exclusively vertical in brooding corals. Instead, we show that Symbiodinium transmission in S. hystrix involves a mixed-mode strategy, similar to many terrestrial invertebrate symbioses. Also, variation in the abundances of common Symbiodinium types among adult corals suggests that microhabitat differences influence the structure of in hospite Symbiodinium communities. Partial genetic regulation coupled with flexibility in the environmentally acquired component of Symbiodinium communities implies that corals with vertical transmission, like S. hystrix, may be more resilient to environmental change than previously thought. PMID- 29453424 TI - Genetic control and evolutionary potential of a constitutive resistance mechanism against the spruce budworm (Choristoneura fumiferana) in white spruce (Picea glauca). AB - Insect herbivory may drive evolution by selecting for trees with heritable resistance against defoliation. The spruce budworm (Choristoneura fumiferana, SBW) is a highly damaging forest insect pest that can affect population structure of white spruce (Picea glauca) in North America. Resistance against SBW was recently described in white spruce and was linked to three constitutive resistance biomarkers: the phenolic compounds piceol and pungenol, and expression of a beta-glucosidase encoding gene (Pgbetaglu-1). We investigated the phenotypic variability and heritability of these resistance biomarkers and of picein, the precursor of piceol, in the foliage of 874 trees belonging to 33 full-sib families and 71 clonal lines under evaluation in seven field locations in Eastern Canada. We aimed to (i) determine their genetic control, (ii) estimate the genetic and phenotypic correlations among defense biomarkers, and (iii) determine whether their constitutive levels are associated with detrimental trade-offs on growth. Quantitative genetics analyses indicated that all four traits are moderately to highly heritable. The full-sib and clonal analyses showed that additive and non-additive genetic effects play major and minor roles, respectively. Positive genetic and phenotypic correlations between resistance biomarkers and primary growth indicated that there is no trade-off between total height and height increment and resistance traits, contradicting the GDBH (Growth Differentiation Balance Hypothesis). Our findings about the predominant additive genetic basis of the resistance biomarkers show that adaptive evolution of white spruce natural populations to resist to SBW is possible and that potentially important gains could also be expected from artificial selection. PMID- 29453426 TI - Importance of embryo aneuploidy screening in preimplantation genetic diagnosis for monogenic diseases using the karyomap gene chip. AB - We investigated the incidence of aneuploidy in embryos from couples carrying monogenic diseases and the effect of embryo aneuploidy screening on the monogenic disease preimplantation genetic diagnosis (PGD). From November 2014 to April 2017, 36 couples carrying monogenic diseases were enrolled. The karyomap gene chip technique was used to analyze the blastocysts from the subjects and select normal embryos for transfer. A total of 43 single-gene PGD cycles were performed. A total of 687 eggs were obtained and 186 blastocysts were biopsed. After analysis via karyomap chip, 175 blastocysts received diagnostic results. In our monogenic disease PGD, 66.8% (117/175) of the embryos were diagnosed as normal or non-pathogenic (silent carriers), and 33.2% (58/175) of the embryos were diagnosed as abnormal or pathogenic. For preimplantation genetic screening (PGS), the aneuploidy rate of embryos was 22.9% (40/175). Among embryos diagnosed as normal for monogenic diseases, 26.5% (31/117) of the embryos were aneuploid and could not be transferred. Thus, approximately 1/4 of normal or non-pathogenic blastocysts diagnosed based on monogenic disease PGD were aneuploid, indicating the necessity and importance of embryo aneuploidy screening during PGD for monogenic diseases. PMID- 29453425 TI - Chronic treatment with fluoride affects the jejunum: insights from proteomics and enteric innervation analysis. AB - Gastrointestinal symptoms are the first signs of fluoride (F) toxicity. In the present study, the jejunum of rats chronically exposed to F was evaluated by proteomics, as well as by morphological analysis. Wistar rats received water containing 0, 10 or 50 mgF/L during 30 days. HuC/D, neuronal Nitric Oxide (nNOS), Vasoactive Intestinal Peptide (VIP), Calcitonin Gene Related Peptide (CGRP), and Substance P (SP) were detected in the myenteric plexus of the jejunum by immunofluorescence. The density of nNOS-IR neurons was significantly decreased (compared to both control and 10 mgF/L groups), while the VIP-IR varicosities were significantly increased (compared to control) in the group treated with the highest F concentration. Significant morphological changes were seen observed in the density of HUC/D-IR neurons and in the area of SP-IR varicosities for F treated groups compared to control. Changes in the abundance of various proteins correlated with relevant biological processes, such as protein synthesis, glucose homeostasis and energy metabolism were revealed by proteomics. PMID- 29453427 TI - Orthodox religious fasting as a medical nutrition therapy for dyslipidemia: where do we stand and how far can we go? AB - Previous studies have reported inconclusive results regarding the effects of Orthodox religious fasting (OF) on common cardiovascular risk factors, including arterial hypertension and diabetes. Contrariwise, an optimal effect on dyslipidemia has been demonstrated and significant reductions in total cholesterol (TC) and low-density lipoprotein-cholesterol (LDL-C) concentrations, in Orthodox populations without comorbidities, have been consistently reported. This favorable effect on lipid homeostasis is probably facilitated by a broad lifestyle modification related to OF, extended beyond dietary habits. However, several clinical issues require further clarification by future trials including the efficacy and safety of OF in specific groups of patients with dyslipidemia, mainly those with cardiovascular disease and diabetes, the effects of OF on high density lipoprotein-cholesterol (HDL-C), the dietary limitations of specific vitamins and minerals during fasting, as well as the optimal duration of this dietary intervention. The present article aims to discuss, whether there is a strong enough theoretical background, to currently support the implementation of OF as a medical nutrition therapy for dyslipidemia in the daily clinical setting, with a discourse on available evidence and future research agenda. PMID- 29453428 TI - IGF-I and IGFBP-3 concentrations at 2 years: associations with anthropometry and milk consumption in an Indian cohort. AB - BACKGROUND/OBJECTIVES: To ascertain associations between plasma insulin-like growth factor I (IGF-I), insulin-like growth factor-binding protein 3 (IGFBP-3) and their molar ratio at 2 y with neonatal size, infant growth, body composition at 2 y, and feeding practices in an Indian cohort. SUBJECTS/METHODS: A cohort of 209 newborns, with 122 followed at 2 y. Anthropometry was conducted at birth and 2 y. IGF-I and IGFBP-3 concentrations were measured in cord blood and at 2 y. Maternal and child diet was assessed by food frequency questionnaires and maternal interviews. Multivariate regression was used to test for associations adjusting for confounding factors. RESULTS: Mean 2 y plasma IGF-I and IGFBP-3 concentrations and IGF-I/IGFBP-3 were 49.4 ng/ml (95% CI: 44.1, 54.8), 1953.8 ng/ml (CI: 1870.6, 2036.9) ng/ml, and 0.088 (CI: 0.081, 0.095), respectively. IGF I and IGF-I/IGFBP-3 were positively associated with current length, but not body mass index or adiposity. IGF-I was higher among those with greater change in length since birth. IGF-I concentrations were higher in children who drank the most milk (>500 vs. <250 ml per day: 65.6 vs. 42.8 ng/ml, p < 0.04), received other milk <6 months compared to >=6 months (56.3 vs. 44.8 ng/ml, p < 0.05), and in those whose mothers consumed milk daily vs. less frequently in late pregnancy (56.4 vs. 42.7 ng/ml, p < 0.01). In multivariate regression, 2 y IGF-I concentration and IGF-I/IGFBP-3 were each positively associated with current length and milk intake. IGFBP-3 was not related to anthropometry or milk intake. CONCLUSIONS: Plasma IGF-I concentrations and IGF-I/IGFBP-3 at 2 y are positively associated with length at 2 y and current milk intake. PMID- 29453429 TI - Human neutrophils can mimic myeloid-derived suppressor cells (PMN-MDSC) and suppress microbead or lectin-induced T cell proliferation through artefactual mechanisms. AB - We report that human conventional CD15+ neutrophils can be isolated in the peripheral blood mononuclear cell (PBMC) layer during Ficoll gradient separation, and that they can impair T cell proliferation in vitro without concomitant neutrophil activation and killing. This effect was observed in a total of 92 patients with organ transplants, lung cancer or anxiety/depression, and in 18 healthy donors. Although such features are typically associated in the literature with the presence of certain myeloid-derived suppressor cell (PMN-MDSC) populations, we found that commercial centrifuge tubes that contained membranes or gels for PBMC isolation led to up to 70% PBMC contamination by CD15+ neutrophils, with subsequent suppressive effects in certain cellular assays. In particular, the suppressive activity of human MDSC should not be evaluated using lectin or microbead stimulation, whereas assays involving soluble or plate-bound antibodies or MLR are unaffected. We conclude that CD15+ neutrophil contamination, and associated effects on suppressor assays, can lead to significant artefacts in studies of human PMN-MDSC. PMID- 29453430 TI - Increased deficit of visual attention span with development in Chinese children with developmental dyslexia. AB - It has been suggested that orthographic transparency and age changes may affect the relationship between visual attention span (VAS) deficit and reading difficulty. The present study explored the developmental trend of VAS in children with developmental dyslexia (DD) in Chinese, a logographic language with a deep orthography. Fifty-seven Chinese children with DD and fifty-four age-matched normal readers participated. The visual 1-back task was adopted to examine VAS. Phonological and morphological awareness tests, and reading tests in single character and sentence levels were used for reading skill measurements. Results showed that only high graders with dyslexia exhibited lower accuracy than the controls in the VAS task, revealing an increased VAS deficit with development in the dyslexics. Moreover, the developmental trajectory analyses demonstrated that the dyslexics seemed to exhibit an atypical but not delayed pattern in their VAS development as compared to the controls. A correlation analysis indicated that VAS was only associated with morphological awareness for dyslexic readers in high grades. Further regression analysis showed that VAS skills and morphological awareness made separate and significant contributions to single-character reading for high grader with dyslexia. These findings suggested a developmental increasing trend in the relationship between VAS skills and reading (dis)ability in Chinese. PMID- 29453431 TI - Delayed gut microbiota development in high-risk for asthma infants is temporarily modifiable by Lactobacillus supplementation. AB - Gut microbiota dysbiosis and metabolic dysfunction in infancy precedes childhood atopy and asthma development. Here we examined gut microbiota maturation over the first year of life in infants at high risk for asthma (HR), and whether it is modifiable by early-life Lactobacillus supplementation. We performed a longitudinal comparison of stool samples collected from HR infants randomized to daily oral Lactobacillus rhamnosus GG (HRLGG) or placebo (HRP) for 6 months, and healthy (HC) infants. Meconium microbiota of HRP participants is distinct, follows a delayed developmental trajectory, and is primarily glycolytic and depleted of a range of anti-inflammatory lipids at 6 months of age. These deficits are partly rescued in HRLGG infants, but this effect was lost at 12 months of age, 6 months after cessation of supplementation. Thus we show that early-life gut microbial development is distinct, but plastic, in HR infants. Our findings offer a novel strategy for early-life preventative interventions. PMID- 29453432 TI - Validation of house-keeping genes for normalization of gene expression data during diurnal/circadian studies in rice by RT-qPCR. AB - The circadian clock in plants is the intrinsic rhythmic expression of thousands of genes in a 24 h period, which is set by the day-night cycles in the environment. The study of the circadian clock often requires expression profiling of genes over a large number of samples for which RT-qPCR is invariably used. Reliability of the results depends largely on the house-keeping genes, which serve as control and thus should be chosen carefully to prevent erroneous results. In this study, ten house-keeping genes were chosen from rice for stability analysis with 48 tissue samples harvested from plants subjected to diurnal/circadian cycles. Although, all the genes were found to be stable, however, six of them showed cyclic expression patterns and caused major changes in the expression profiles of the target genes when used to normalize their expression data, thereby making them poor candidates for diurnal/circadian studies. In conclusion, reference genes need to be selected for diurnal/circadian studies with extra caution as more than 80% of transcriptome in plants undergoes cycling, which remains undetected by the gene stability assessment software and can severely affect the RT-qPCR based gene expression profiling. The geometric mean of two or more most stable reference genes is hence recommended for diurnal/circadian studies in plants. PMID- 29453433 TI - Randomized trial of earlier versus later oral feeding in very premature infants. AB - OBJECTIVES: To ascertain if earlier oral feeding initiation results in earlier attainment of full oral feedings/hospital discharge in very premature infants. STUDY DESIGN: Eligible infants born at <29 weeks' gestation were randomized at 30 weeks' postmenstrual age (PMA) to initiate oral feedings at 30 weeks' PMA (Earlier Oral Feeding Group) versus 33 weeks' PMA (Later Oral Feeding Group). RESULTS: Thirty-four infants were randomized to the Earlier Oral Feeding Group and 32 to the Later Oral Feeding Group. There were no significant differences in our primary outcomes of PMA at full oral feedings (mean difference -0.5 weeks, 95% CI: -2.2 to +1.2 weeks) or hospital discharge (mean difference -0.2 weeks, 95% CI: -1.8 to +1.4 weeks). CONCLUSIONS: Initiating oral feeding attempts in very premature infants at 30 weeks' PMA does not result in earlier attainment of full oral feedings or discharge but is safe for infants who are not severely tachypneic or receiving positive pressure. PMID- 29453434 TI - Post-ligation cardiac syndrome is associated with increased morbidity in preterm infants. AB - OBJECTIVE: The influence of post-ligation cardiac syndrome (PLCS), a complication of patent ductus arteriosus (PDA) ligations, on neonatal outcomes is unknown. The purpose of this study was to determine the risks of PLCS on severe pulmonary morbidity and severe retinopathy of prematurity (ROP). STUDY DESIGN: Retrospective cohort study of infants who underwent a PDA ligation between 2006 and 2015. Data were collected on patients with and without PLCS. The primary outcome was the difference in severe bronchopulmonary dysplasia (BPD) between groups. Secondary outcomes included discharge with home oxygen and severe ROP. RESULT: A total of 100 infants that underwent PDA ligation during the study period were included in the study; 31 (31%) neonates developed PLCS. In adjusted analysis, PLCS was associated with increased risk for severe BPD (RR 1.67, 95% CI: 1.15-2.42) and home oxygen therapy (RR: 1.47, 95% CI: 1.09-1.99) only. No association with severe ROP was seen (RR: 1.48; 95% CI: 0.87-2.52). CONCLUSION: PLCS is associated with severe neonatal pulmonary morbidity, but not with severe ROP. Further investigation is warranted to validate these results. PMID- 29453435 TI - Evidence of a gene-environment interaction of NODAL variants and inflammation in preterm birth. AB - OBJECTIVE: NODAL has been implicated in timing of parturition and immune regulation. We investigated the relationship between NODAL polymorphisms, infection/inflammation, and preterm birth. STUDY DESIGN: For this secondary analysis, 613 women (189 preterm and 424 term) from the Montreal Prematurity Study were genotyped for NODAL polymorphisms and assessed for bacterial vaginosis and placental inflammation. RESULT: NODAL polymorphisms were not associated with preterm birth. However, the rs2231947(C>T) variant allele was associated with increased risk for preterm birth among women with bacterial vaginosis (odds ratio: 2.76, 95% confidence interval: 1.12-6.85). Among women without placental inflammation, the rs1904589(A>G) variant allele was associated with increased risk of preterm birth (odds ratio: 1.31, 95% confidence interval: 1.02-1.70). Among women with placental inflammation, the rs10999338(C>T) variant allele was associated with reduced risk of preterm birth (odds ratio: 0.50, 95% confidence interval: 0.29-0.87). CONCLUSION: The effect of NODAL polymorphisms on preterm birth depends on maternal infection/inflammation status.

AB - OBJECTIVES: To quantify drive distances to hospital obstetric services and advanced neonatal care and to examine such disparities by residential rurality and insurance type. STUDY DESIGN: Data for all-payer maternal childbirth hospitalizations in 2002 (N = 661,240) and 2013 (N = 634,807) from nine geographically dispersed states were linked with the American Hospital Association annual surveys to identify maternal residence zip codes and the addresses of hospitals with obstetric services or advanced neonatal care. RESULTS: The uneven geographic distribution of hospital obstetric and advanced neonatal care increased between 2002 and 2013, varying by maternal residential rurality and insurance type. Women in rural non-core areas, with Medicaid or no insurance, and living in counties with lower income and educational attainment, had to travel farther to the nearest hospital with obstetric services or neonatal care than their counterparts. CONCLUSIONS: Women in communities that are already socioeconomically disadvantaged face increasing and substantial travel distances to access perinatal care.

AB - Plasmacytoid dendritic cells (pDCs) play a key role in the immune response against viruses. In addition, recent research has suggested that pDCs possess direct and indirect tumoricidal activities. We previously found that a lactic acid bacteria strain, Lactococcus lactis JCM 5805 (LC-Plasma), stimulated pDCs and prevented viral infection in mouse and human studies. Meanwhile, emulsifiers have recently been highlighted as candidate adjuvants for some viral vaccines and cancer immunotherapies. In this study, we discovered some specific emulsifiers, mainly consisting of sucrose fatty acid esters, that drastically enhance the potency of LC-Plasma to activate pDCs in vitro. The emulsifiers promoted the efficient uptake of LC-Plasma by pDCs and the ratio of pDCs that took up LC Plasma correlated with the activity of pDCs. In addition, an in vivo study showed that oral treatment with LC-Plasma mixed with an emulsifier induced a higher expression of genes related to anti-viral immunity in the lung compared to treatment with LC-Plasma alone. Both LC-Plasma and the emulsifiers used in this study have been confirmed to be safe for human use. Therefore, LC-Plasma mixed with an emulsifier might be a useful tool for certain anti-cancer and anti-viral therapies. PMID- 29453438 TI - Altered immunity in crowded Mythimna separata is mediated by octopamine and dopamine. AB - Similar to pathogenic infection, high population density alters insects' prophylactic immunity. Density-dependent prophylaxis has been reported in many polyphenic insects, but the regulatory mechanism underlying this phenomenon remains unclear. The biogenic monoamines are known to play critical roles in mediating insect immune responses. In the current study, the immune capacity and the levels of three biogenic monoamines were investigated in the polyphenic larvae of Mythimna separata, reared at the densities of 1, 2, 5, 10, and 30 larvae per 650-mL jar. Concomitant with the increased phenoloxidase (PO) activity and total haemocyte count in the larvae at high densities (5, 10, 30 larvae/jar), the octopamine level was also increased. In contrast, the dopamine level was decreased, and the 5-hydroxytryptamine level was not significantly affected. Injection of octopamine induced significant increases in the total haemocyte count and PO activity. Conversely, epinastine, a specific antagonist of octopamine, decreased the total haemocyte count and PO activity. Another octopamine antagonist, phentolamine, inhibited the activity of PO and lysozymes. In addition, injection of dopamine induced a significant increase in PO activity and decreased the total haemocyte count and lysozyme activity. These results suggested that both octopamine and dopamine mediate the increases in total haemocyte count and PO activity in the crowded larvae.

AB - Understanding the rhizodeposited carbon (C) dynamics of winter wheat (Triticum aestivum L.), is crucial for soil fertility and C sequestration. Pot-grown winter wheat was pulse labelled with 14CO2 at the key growth stages. 14C in the shoots, roots and soil was measured at 5 or 2 days after 14C-labelling (DAL 5/2) at each growth stage and at harvest. The 14C in the shoots increased from 4% of the net 14C recovered (shoots + roots + soil) during tillering to 53% at harvest. Approximately 14-34% of the net 14C recovered was incorporated into the soil. Allocation of photosynthesized C was extrapolated from the pot experiment to field condition, assuming a planting density of 1.8 million plants ha-1. The estimated C input to the soil was 1.7 t C ha-1, and 0.7 t C ha-1 of root residues was retained after wheat harvest; both values were higher than those previously reported (0.6 and 0.4 t C ha-1, respectively). Our findings highlight that C tracing during the entire crop season is necessary to quantify the temporal allocation of photosynthesized C, especially the contribution to soil carbon in intensified farming system. PMID- 29453439 TI - Working Memory And Brain Tissue Microstructure: White Matter Tract Integrity Based On Multi-Shell Diffusion MRI. AB - Working memory is a complex cognitive process at the intersection of sensory processing, learning, and short-term memory and also has a general executive attention component. Impaired working memory is associated with a range of neurological and psychiatric disorders, but very little is known about how working memory relates to underlying white matter (WM) microstructure. In this study, we investigate the association between WM microstructure and performance on working memory tasks in healthy adults (right-handed, native English speakers). We combine compartment specific WM tract integrity (WMTI) metrics derived from multi-shell diffusion MRI as well as diffusion tensor/kurtosis imaging (DTI/DKI) metrics with Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) subtests tapping auditory working memory. WMTI is a novel tool that helps us describe the microstructural characteristics in both the intra- and extra-axonal environments of WM such as axonal water fraction (AWF), intra-axonal diffusivity, extra-axonal axial and radial diffusivities, allowing a more biophysical interpretation of WM changes. We demonstrate significant positive correlations between AWF and letter-number sequencing (LNS), suggesting that higher AWF with better performance on complex, more demanding auditory working memory tasks goes along with greater axonal volume and greater myelination in specific regions, causing efficient and faster information process. PMID- 29453441 TI - Circulating cell-free mitochondrial DNA, but not leukocyte mitochondrial DNA copy number, is elevated in major depressive disorder. AB - Major depressive disorder (MDD) has been linked to mitochondrial defects, which could manifest in mitochondrial DNA (mtDNA) polymorphisms or mutations. Additionally, copy number of mtDNA (mtDNA-cn) can be quantified in peripheral blood mononuclear cells (PBMC)s, indirectly reflecting cellular energetics, or in the circulating cell-free mtDNA (ccf-mtDNA) levels, which may reflect a fraction of the mitochondrial genome released during cellular stress. Few studies have examined ccf-mtDNA in MDD, and no studies have tested its relationship with intracellular mtDNA-cn or with antidepressant treatment response. Here, mtDNA levels were quantified in parallel from: (i) PBMCs and (ii) cell-free plasma of 50 unmedicated MDD subjects and 55 controls, in parallel with PBMC telomere length (TL) and antioxidant enzyme glutathione peroxidase (GpX) activity. MtDNA measures were repeated in 19 MDD subjects after 8 weeks of open-label SSRI treatment. In analyses adjusted for age, sex, BMI, and smoking, MDD subjects had significantly elevated levels of ccf-mtDNA (F = 20.6, p = 0.00002). PBMC mtDNA-cn did not differ between groups (p > 0.4). In preliminary analyses, we found that changes in ccf-mtDNA with SSRI treatment differed between SSRI responders and non responders (F = 6.47, p = 0.02), with the non-responders showing an increase in ccf-mtDNA and responders not changing. Baseline ccf-mtDNA was positively correlated with GpX (r = 0.32, p = 0.001), and PBMC mtDNA correlated positively with PBMC TL (r = 0.38, p = 0.0001). These data suggest that plasma ccf-mtDNA and PBMC mtDNA-cn reflect different cellular processes and that the former may be more reflective of certain aspects of MDD pathophysiology and of the response to SSRI antidepressants. PMID- 29453442 TI - White matter integrity in medication-free women with peripartum depression: a tract-based spatial statistics study. AB - Diffusion tensor imaging (DTI) studies in depression show decreased structural connectivity in the left anterior limb of the internal capsule and the genu of the corpus callosum but no such studies exist in peripartum depression (PPD), which affects 1 in 8 women. We analyzed fractional anisotropy (FA) as a measure of white matter integrity of these two tracts using tract-based spatial statistics (TBSS). We then conducted an exploratory whole-brain analysis to identify additional regions implicated in PPD. Seventy-five pregnant, medication free women were evaluated with the Edinburgh Postnatal Depression Scale (EPDS) and Structured Clinical Interview (SCID) for DSM-IV-TR in pregnancy and in the postpartum. Structural MRI and DTI sequences were acquired in forty-four women within 2-8 weeks postpartum. TBSS data were analyzed between healthy comparison postpartum women (HCW) and women who developed PPD to determine differences in white matter integrity within the left anterior limb of the internal capsule and the genu of the corpus callosum, then analyzed across participants to explore correlation between FA and the EPDS score. An exploratory whole-brain analysis was also conducted to identify other potential regions showing differences in white matter integrity between groups, as well as correlation between EPDS and FA across groups. All results were corrected for multiple comparisons and analyses conducted using FSL, p < 0.05, K > 10. In comparison to HCW, women with PPD had significantly lower FA in left anterior limb of the internal capsule (p = 0.010). FA was negatively correlated with EPDS scores in the left anterior limb of the internal capsule (p = 0.019). In the whole-brain analysis, FA in the right retrolenticular internal capsule (p = 0.03) and two clusters within the body of the corpus callosum (p = 0.044, p = 0.050) were negatively correlated with EPDS; there were no between-group differences in FA. Reduced FA in the left anterior limb of the internal capsule suggests disruption of fronto-subcortical circuits in PPD. A negative correlation between FA within the body of the corpus callosum and EPDS total score could additionally reflect disrupted interhemispheric structural connectivity in women with depressive symptoms. PMID- 29453443 TI - Role of the mesolimbic dopamine system in relief learning. AB - The relief from an aversive event is rewarding. Since organisms are able to learn which environmental cues can cease an aversive event, relief learning helps to better cope with future aversive events. Literature data suggest that relief learning is affected in various psychopathological conditions, such as anxiety disorders. Here, we investigated the role of the mesolimbic dopamine system in relief learning. Using a relief learning procedure in Sprague Dawley rats, we applied a combination of behavioral experiments with anatomical tracing, c-Fos immunohistochemistry, and local chemogenetic and pharmacological interventions to broadly characterize the role of the mesolimbic dopamine system. The present study shows that a specific part of the mesolimbic dopamine system, the projection from the posterior medial ventral tegmental area (pmVTA) to the nucleus accumbens shell (AcbSh), is activated by aversive electric stimuli. 6 OHDA lesions of the pmVTA blocked relief learning but fear learning and safety learning were not affected. Chemogenetic silencing of the pmVTA-AcbSh projection using the DREADD approach, as well as intra-AcbSh injections of the dopamine D2/3 receptor antagonist raclopride inhibited relief learning. Taken together, the present data demonstrate that the dopaminergic pmVTA-AcbSh projection is critical for relief learning but not for similar learning phenomena. This novel finding may have clinical implications since the processing of signals predicting relief and safety is often impaired in patients suffering from anxiety disorders. Furthermore, it may help to better understand psychological conditions like non suicidal self-injury, which are associated with pain offset relief. PMID- 29453444 TI - Positive regulation of raphe serotonin neurons by serotonin 2B receptors. AB - Serotonin is a neurotransmitter involved in many psychiatric diseases. In humans, a lack of 5-HT2B receptors is associated with serotonin-dependent phenotypes, including impulsivity and suicidality. A lack of 5-HT2B receptors in mice eliminates the effects of molecules that directly target serotonergic neurons including amphetamine derivative serotonin releasers, and selective serotonin reuptake inhibitor antidepressants. In this work, we tested the hypothesis that 5 HT2B receptors directly and positively regulate raphe serotonin neuron activity. By ex vivo electrophysiological recordings, we report that stimulation by the 5 HT2B receptor agonist, BW723C86, increased the firing frequency of serotonin Pet1 positive neurons. Viral overexpression of 5-HT2B receptors in these neurons increased their excitability. Furthermore, in vivo 5-HT2B-receptor stimulation by BW723C86 counteracted 5-HT1A autoreceptor-dependent reduction in firing rate and hypothermic response in wild-type mice. By a conditional genetic ablation that eliminates 5-HT2B receptor expression specifically and exclusively from Pet1 positive serotonin neurons (Htr2b 5-HTKO mice), we demonstrated that behavioral and sensitizing effects of MDMA (3,4-methylenedioxy-methamphetamine), as well as acute behavioral and chronic neurogenic effects of the antidepressant fluoxetine, require 5-HT2B receptor expression in serotonergic neurons. In Htr2b 5-HTKO mice, dorsal raphe serotonin neurons displayed a lower firing frequency compared to control Htr2b lox/lox mice as assessed by in vivo extracellular recordings and a stronger hypothermic effect of 5-HT1A-autoreceptor stimulation was observed. The increase in head-twitch response to DOI (2,5-dimethoxy-4-iodoamphetamine) further confirmed the lower serotonergic tone resulting from the absence of 5-HT2B receptors in serotonin neurons. Together, these observations indicate that the 5 HT2B receptor acts as a direct positive modulator of serotonin Pet1-positive neurons in an opposite way as the known 5-HT1A-negative autoreceptor. PMID- 29453445 TI - Alterations in interhemispheric gamma-band connectivity are related to the emergence of auditory verbal hallucinations in healthy subjects during NMDA receptor blockade. AB - Auditory verbal hallucinations (AVH) are a common positive symptom of schizophrenia. Excitatory-to-inhibitory (E/I) imbalance related to disturbed N methyl-D-aspartate receptor (NMDAR) functioning has been suggested as a possible mechanism underlying altered connectivity and AVH in schizophrenia. The current study examined the effects of ketamine, a NMDAR antagonist, on glutamate-related mechanisms underlying interhemispheric gamma-band connectivity, conscious auditory perception during dichotic listening (DL), and the emergence of auditory verbal distortions and hallucinations (AVD/AVH) in healthy volunteers. In a single-blind, pseudo-randomized, placebo-controlled crossover design, nineteen male, right-handed volunteers were measured using 64 channel electroencephalography (EEG). Psychopathology was assessed with the PANSS interview and the 5D-ASC questionnaire, including a subscale to detect auditory alterations with regard to AVD/AVH (AUA-AVD/AVH). Interhemispheric connectivity analysis was performed using eLORETA source estimation and lagged phase synchronization (LPS) in the gamma-band range (30-100 Hz). Ketamine induced positive symptoms such as hallucinations in a subgroup of healthy subjects. In addition, interhemispheric gamma-band connectivity was found to be altered under ketamine compared to placebo, and subjects with AUA-AVD/AVH under ketamine showed significantly higher interhemispheric gamma-band connectivity than subjects without AUA-AVD/AVH. These findings demonstrate a relationship between NMDAR functioning, interhemispheric connectivity in the gamma-band frequency range between bilateral auditory cortices and the emergence of AVD/AVH in healthy subjects. The result is in accordance with the interhemispheric miscommunication hypothesis of AVH and argues for a possible role of glutamate in AVH in schizophrenia. PMID- 29453446 TI - Environmental, genetic and epigenetic contributions to cocaine addiction. AB - Decades of research on cocaine has produced volumes of data that have answered many important questions about the nature of this highly addictive drug. Sadly, none of this information has translated into the development of effective therapies for the treatment of cocaine addiction. This review endeavors to assess the current state of cocaine research in an attempt to identify novel pathways for therapeutic development. For example, risk of cocaine addiction is highly heritable but genome-wide analyses comparing cocaine-dependent individuals to controls have not resulted in promising targets for drug development. Is this because the genetics of addiction is too complex or because the existing research methodologies are inadequate? Likewise, animal studies have revealed dozens of enduring changes in gene expression following prolonged exposure to cocaine, none of which have translated into therapeutics either because the resulting compounds were ineffective or produced intolerable side-effects. Recently, attention has focused on epigenetic modifications resulting from repeated cocaine intake, some of which appear to be heritable through changes in the germline. While epigenetic changes represent new vistas for therapeutic development, selective manipulation of epigenetic marks is currently challenging even in animals such that translational potential is a distant prospect. This review will reveal that despite the enormous progress made in understanding the molecular and physiological bases of cocaine addiction, there is much that remains a mystery. Continued advances in genetics and molecular biology hold potential for revealing multiple pathways toward the development of treatments for the continuing scourge of cocaine addiction. PMID- 29453448 TI - The gastrointestinal tract microbiota of northern white-cheeked gibbons (Nomascus leucogenys) varies with age and captive condition. AB - Nutrition and health of northern white-cheeked gibbons (Nomascus leucogenys) are considered to be primarily influenced by the diversity of their gastrointestinal tract (GIT) microbiota. However, the precise composition, structure, and role of the gibbon GIT microbiota remain unclear. Microbial communities from the GITs of gibbons from Nanning (NN, n = 36) and Beijing (BJ, n = 20) Zoos were examined through 16S rRNA sequencing. Gibbon's GITs microbiomes contained bacteria from 30 phyla, dominated by human-associated microbial signatures: Firmicutes, Bacteroidetes, and Proteobacteria. Microbial species richness was markedly different between adult gibbons (>8 years) under distinct captive conditions. The relative abundance of 14 phyla varied significantly in samples of adults in BJ versus NN. Among the age groups examined in NN, microbiota of adult gibbons had greater species variation and richer community diversity than microbiota of nursing young (<6 months) and juveniles (2-5 years). Age-dependent increases in the relative abundances of Firmicutes and Fibrobacteres were detected, along with simultaneous increases in dietary fiber intake. A few differences were detected between sex cohorts in NN, suggesting a very weak correlation between sex and GIT microbiota. This study is the first to taxonomically identify gibbon's GITs microbiota confirming that microbiota composition varies with age and captive condition. PMID- 29453447 TI - Embryonic stem cell transplants as a therapeutic strategy in a rodent model of autism. AB - Autism is a neurodevelopmental disorder characterized by disruptions in three core behavioral domains: deficits in social interaction, impairments in communication, and repetitive and stereotyped patterns of behavior or thought. There are currently no drugs available for the treatment of the core symptoms of ASD and drugs that target comorbid symptoms often have serious adverse side effects, suggesting an urgent need for new therapeutic strategies. The neurobiology of autism is complex, but converging evidence suggests that ASD involves disruptions in the inhibitory GABAergic neurotransmitter system. Specifically, people with autism have a reduction in parvalbumin (PV)-containing interneurons in the PFC, leading to the suggestion that restoring interneuron function in this region may be a novel therapeutic approach for ASD. Here we used a dual-reporter embryonic stem cell line to generate enriched populations of PV positive interneurons, which were transplanted into the medial prefrontal cortex (mPFC) of the Poly I:C rodent model of autism. PV interneuron transplants were able to decrease pyramidal cell firing in the mPFC and alleviated deficits in social interaction and cognitive flexibility. Our results suggest that restoring PV interneuron function in the mPFC may be a novel and effective treatment strategy to reduce the core symptoms of autism. PMID- 29453449 TI - Functional analysis of SLC39A8 mutations and their implications for manganese deficiency and mitochondrial disorders. AB - SLC39A8 encodes ZIP8, a divalent metal ion transporter. Mutations in the SLC39A8 gene are associated with congenital disorder of glycosylation type II and Leigh syndrome. Notably, affected patients with both disorders exhibited severe manganese (Mn) deficiency. The cellular function of human SLC39A8 (hSLC39A8) and the mechanisms by which mutations in this protein lead to human diseases are unclear. Herein, we show that hSLC39A8 mediates 54Mn uptake by the cells, and its expression is regulated by Mn. While expression of wild-type hSLC39A8 increased 54Mn uptake activity, disease-associated mutations abrogated the ability of the transporter to mediate Mn uptake into the cells, thereby providing a causal link to severe Mn deficiency. All mutants failed to localize on the cell surface and were retained within the endoplasmic reticulum. Interestingly, expression of hSLC39A8 mutants of both CDG type II and Leigh syndrome reduced mitochondrial 54Mn levels and activity of Mn-dependent mitochondrial superoxide dismutase MnSOD, and in turn increased oxidative stress. The expression of wild-type hSLC39A8, but not the disease-associated mutants, promoted mitochondrial functions. Moreover, loss of function analyses further corroborate hSLC39A8's critical role in mediating Mn uptake and mitochondrial function. Our results provide a potential pathogenic mechanism of diseases that are associated with hSLC39A8 mutations. PMID- 29453450 TI - Insights into the inhibitory mechanisms of NADH on the alphagamma heterodimer of human NAD-dependent isocitrate dehydrogenase. AB - Human NAD-dependent isocitrate dehydrogenase (NAD-IDH) catalyzes the oxidative decarboxylation of isocitrate in the citric acid cycle. In the alpha2betagamma heterotetramer of NAD-IDH, the gamma subunit plays the regulatory role and the beta subunit the structural role. Previous biochemical data have shown that mammalian NAD-IDHs can be inhibited by NADH; however, the molecular mechanism is unclear. In this work, we show that the alphabeta, alphagamma and alpha2betagamma enzymes of human NAD-IDH can be inhibited by NADH, and further determine the crystal structure of the alphagamma heterodimer bound with an Mg2+ and an NADH at the active site and an NADH at the allosteric site, which resembles that of the inactive alphaMggamma heterodimer. The NADH at the active site occupies the binding site for NAD+ and prevents the binding of the cofactor. The NADH at the allosteric site occupies the binding sites for ADP and citrate and blocks the binding of the activators. The biochemical data confirm that the NADH binding competes with the binding of NAD+ and the binding of citrate and ADP, and the two effects together contribute to the NADH inhibition on the activity. These findings provide insights into the inhibitory mechanisms of the alphagamma heterodimer by NADH. PMID- 29453451 TI - Prevalence and impact of baseline resistance-associated substitutions on the efficacy of ledipasvir/sofosbuvir or simeprevir/sofosbuvir against GT1 HCV infection. AB - Baseline resistance-associated substitutions (RASs) have variable impacts in clinical trials but their prevalence and impact in real-world patients remains unclear. We performed baseline resistance testing using a commercial assay (10% cutoff) for 486 patients treated with LDV/SOF or SMV/SOF, with or without ribavirin, in the multi-center, observational HCV-TARGET cohort. Linkage of RASs was evaluated in selected samples using a novel quantitative single variant sequencing assay. Our results showed that the prevalence of NS3, NS5A, NS5B RASs was 45%, 13%, and 8%, respectively, and 10% of patients harbored RASs in 2 or more drug classes. Baseline LDV RASs in GT1a, TE, and cirrhosis LDV/SOF subgroup was associated with 2-4% lower SVR12 rates. SMV RASs was associated with lower SVR12 rates in GT1a, treatment-experienced, cirrhotics SMV/SOF subgroup. Pooled analysis of all patients with baseline RASs revealed that SVR12 was 100% (19/19) in patients treated for longer than 98 days but was 87% (81/93) in patients treated for shorter than 98 days. These results demonstrate that RASs prevalence and their impact in real world practice are in general agreement with registration trials, and suggest that longer treatment duration may overcome the negative impact of baseline RASs on SVR12 rates in clinical practice. PMID- 29453453 TI - A Meta-Surface Antenna Array Decoupling (MAAD) Method for Mutual Coupling Reduction in a MIMO Antenna System. AB - In this paper, a method to reduce the inevitable mutual coupling between antennas in an extremely closely spaced two-element MIMO antenna array is proposed. A suspended meta-surface composed periodic square split ring resonators (SRRs) is placed above the antenna array for decoupling. The meta-surface is equivalent to a negative permeability medium, along which wave propagation is rejected. By properly designing the rejection frequency band of the SRR unit, the mutual coupling between the antenna elements in the MIMO antenna system can be significantly reduced. Two prototypes of microstrip antenna arrays at 5.8 GHz band with and without the metasurface have been fabricated and measured. The matching bandwidths of antennas with reflection coefficient smaller than -15 dB for the arrays without and with the metasurface are 360 MHz and 900 MHz respectively. Using the meta-surface, the isolation between elements is increased from around 8 dB to more than 27 dB within the band of interest. Meanwhile, the total efficiency and peak gain of each element, the envelope correlation coefficient (ECC) between the two elements are also improved by considerable amounts. All the results demonstrate that the proposed method is very efficient for enhancing the performance of MIMO antenna arrays. PMID- 29453452 TI - Systematic and stochastic influences on the performance of the MinION nanopore sequencer across a range of nucleotide bias. AB - Emerging sequencing technologies are allowing us to characterize environmental, clinical and laboratory samples with increasing speed and detail, including real time analysis and interpretation of data. One example of this is being able to rapidly and accurately detect a wide range of pathogenic organisms, both in the clinic and the field. Genomes can have radically different GC content however, such that accurate sequence analysis can be challenging depending upon the technology used. Here, we have characterized the performance of the Oxford MinION nanopore sequencer for detection and evaluation of organisms with a range of genomic nucleotide bias. We have diagnosed the quality of base-calling across individual reads and discovered that the position within the read affects base calling and quality scores. Finally, we have evaluated the performance of the current state-of-the-art neural network-based MinION basecaller, characterizing its behavior with respect to systemic errors as well as context- and sequence specific errors. Overall, we present a detailed characterization the capabilities of the MinION in terms of generating high-accuracy sequence data from genomes with a wide range of nucleotide content. This study provides a framework for designing the appropriate experiments that are the likely to lead to accurate and rapid field-forward diagnostics. PMID- 29453454 TI - A Microvascularized Tumor-mimetic Platform for Assessing Anti-cancer Drug Efficacy. AB - Assessment of anti-cancer drug efficacy in in vitro three-dimensional (3D) bioengineered cancer models provides important contextual and relevant information towards pre-clinical translation of potential drug candidates. However, currently established models fail to sufficiently recapitulate complex tumor heterogeneity. Here we present a chip-based tumor-mimetic platform incorporating a 3D in vitro breast cancer model with a tumor-mimetic microvascular network, replicating the pathophysiological architecture of native vascularized breast tumors. The microfluidic platform facilitated formation of mature, lumenized and flow-aligned endothelium under physiological flow recapitulating both high and low perfused tumor regions. Metastatic and non metastatic breast cancer cells were maintained in long-term 3D co-culture with stromal fibroblasts in a poly(ethylene glycol)-fibrinogen hydrogel matrix within adjoining tissue chambers. The interstitial space between the chambers and endothelium contained pores to mimic the "leaky" vasculature found in vivo and facilitate cancer cell-endothelial cell communication. Microvascular pattern dependent flow variations induced concentration gradients within the 3D tumor mass, leading to morphological tumor heterogeneity. Anti-cancer drugs displayed cell type- and flow pattern-dependent effects on cancer cell viability, viable tumor area and associated endothelial cytotoxicity. Overall, the developed microfluidic tumor-mimetic platform facilitates investigation of cancer-stromal endothelial interactions and highlights the role of a fluidic, tumor-mimetic vascular network on anti-cancer drug delivery and efficacy for improved translation towards pre-clinical studies. PMID- 29453455 TI - Temporal structure in spiking patterns of ganglion cells defines perceptual thresholds in rodents with subretinal prosthesis. AB - Subretinal prostheses are designed to restore sight in patients blinded by retinal degeneration using electrical stimulation of the inner retinal neurons. To relate retinal output to perception, we studied behavioral thresholds in blind rats with photovoltaic subretinal prostheses stimulated by full-field pulsed illumination at 20 Hz, and measured retinal ganglion cell (RGC) responses to similar stimuli ex-vivo. Behaviorally, rats exhibited startling response to changes in brightness, with an average contrast threshold of 12%, which could not be explained by changes in the average RGC spiking rate. However, RGCs exhibited millisecond-scale variations in spike timing, even when the average rate did not change significantly. At 12% temporal contrast, changes in firing patterns of prosthetic response were as significant as with 2.3% contrast steps in visible light stimulation of healthy retinas. This suggests that millisecond-scale changes in spiking patterns define perceptual thresholds of prosthetic vision. Response to the last pulse in the stimulation burst lasted longer than the steady state response during the burst. This may be interpreted as an excitatory OFF response to prosthetic stimulation, and can explain behavioral response to decrease in illumination. Contrast enhancement of images prior to delivery to subretinal prosthesis can partially compensate for reduced contrast sensitivity of prosthetic vision.

AB - The goal of replenishing the cardiomyocyte (CM) population using regenerative therapies following myocardial infarction (MI) is hampered by the limited regeneration capacity of adult CMs, partially due to their withdrawal from the cell cycle. Here, we show that microRNA-128 (miR-128) is upregulated in CMs during the postnatal switch from proliferation to terminal differentiation. In neonatal mice, cardiac-specific overexpression of miR-128 impairs CM proliferation and cardiac function, while miR-128 deletion extends proliferation of postnatal CMs by enhancing expression of the chromatin modifier SUZ12, which suppresses p27 (cyclin-dependent kinase inhibitor) expression and activates the positive cell cycle regulators Cyclin E and CDK2. Furthermore, deletion of miR 128 promotes cell cycle re-entry of adult CMs, thereby reducing the levels of fibrosis, and attenuating cardiac dysfunction in response to MI. These results suggest that miR-128 serves as a critical regulator of endogenous CM proliferation, and might be a novel therapeutic target for heart repair. PMID- 29453458 TI - IL-2 Inducible Kinase ITK is Critical for HIV-1 Infection of Jurkat T-cells. AB - Successful replication of Human immunodeficiency virus (HIV)-1 depends on the expression of various cellular host factors, such as the interleukin-2 inducible T-cell kinase (ITK), a member of the protein family of TEC-tyrosine kinases. ITK is selectively expressed in T-cells and coordinates signaling pathways downstream of the T-cell receptor and chemokine receptors, including PLC-1 activation, Ca2+ release, transcription factor mobilization, and actin rearrangements. The exact role of ITK during HIV-1 infection is still unknown. We analyzed the function of ITK during HIV-1 replication and showed that attachment, fusion of virions with the cell membrane and entry into Jurkat T-cells was inhibited when ITK was knocked down. In contrast, reverse transcription and provirus expression were not affected by ITK deficiency. Inhibited ITK expression did not affect the CXCR4 receptor on the cell surface, whereas CD4 and LFA-1 integrin levels were slightly enhanced in ITK knockdown cells and heparan sulfate (HS) expression was completely abolished in ITK depleted T-cells. However, neither HS expression nor other attachment factors could explain the impaired HIV-1 binding to ITK deficient cells, which suggests that a more complex cellular process is influenced by ITK or that not yet discovered molecules contribute to restriction of HIV-1 binding and entry. PMID- 29453459 TI - Ultrahigh resolution radiation imaging system using an optical fiber structure scintillator plate. AB - High resolution imaging of radiation is required for such radioisotope distribution measurements as alpha particle detection in nuclear facilities or high energy physics experiments. For this purpose, we developed an ultrahigh resolution radiation imaging system using an optical fiber structure scintillator plate. We used a ~1-MUm diameter fiber structured GdAlO3:Ce (GAP) /alpha-Al2O3 scintillator plate to reduce the light spread. The fiber structured scintillator plate was optically coupled to a tapered optical fiber plate to magnify the image and combined with a lens-based high sensitivity CCD camera. We observed the images of alpha particles with a spatial resolution of ~25 MUm. For the beta particles, the images had various shapes, and the trajectories of the electrons were clearly observed in the images. For the gamma photons, the images also had various shapes, and the trajectories of the secondary electrons were observed in some of the images. These results show that combining an optical fiber structure scintillator plate with a tapered optical fiber plate and a high sensitivity CCD camera achieved ultrahigh resolution and is a promising method to observe the images of the interactions of radiation in a scintillator.

AB - Some shifts in the gut microbiota composition and its metabolic fingerprints have been associated to Sleeve gastrectomy (SG) and Roux-en-Y Gastric Bypass (RYGB). So far, plasma bile acids have been associated with post-operative glucose improvement and weight loss, but nothing is known about their metabolism in the gut lumen. As bile acids are physiologically transformed by the microbiota into various species, the aim of this work was to study how SG and RYGB-associated dysbiosis impact the bioconversion of bile acids in the intestinal lumen. Comparing SHAM (n = 9) with our validated rat models of SG (n = 5) and RYGB (n = 6), we quantified luminal bile acids along the gut and found that the metabolic transformation of bile acids (deconjugation, dehydroxylation, and epimerization) is not different from the duodenum to the colon. However, in the cecum where the biotransformation mainly takes place, we observed deep alterations of the microbiota composition, which were specific of each type of surgery. In conclusion, despite specific dysbiosis after surgery, the bile acids metabolism in the gut lumen is highly preserved, suggesting that a resilience of the gut microbiota occurs after these procedures. PMID- 29453460 TI - Development and initial characterization of a novel ghrelin receptor CRISPR/Cas9 knockout wistar rat model. AB - BACKGROUND/OBJECTIVES: Ghrelin, a stomach-derived hormone implicated in numerous behaviors including feeding, reward, stress, and addictive behaviors, acts by binding to the growth hormone secretagogue receptor (GHSR). Here, we present the development, verification, and initial characterization of a novel GHSR knockout (KO) Wistar rat model created with CRISPR genome editing. METHODS: Using CRISPR/Cas9, we developed a GHSR KO in a Wistar background. Loss of GHSR mRNA expression was histologically verified using RNAscope in wild-type (WT; n = 2) and KO (n = 2) rats. We tested the effects of intraperitoneal acyl-ghrelin administration on food consumption and plasma growth hormone (GH) concentrations in WT (n = 8) and KO (n = 8) rats. We also analyzed locomotion, food consumption, and body fat composition in these animals. Body weight was monitored from early development to adulthood. RESULTS: The RNAscope analysis revealed an abundance of GHSR mRNA expression in the hypothalamus, midbrain, and hippocampus in WTs, and no observed probe binding in KOs. Ghrelin administration increased plasma GH levels (p = 0.0067) and food consumption (p = 0.0448) in WT rats but not KOs. KO rats consumed less food overall at basal conditions and weighed significantly less compared with WTs throughout development (p = 0.0001). Compared with WTs, KOs presented higher concentrations of brown adipose tissue (BAT; p = 0.0322). CONCLUSIONS: We have verified GHSR deletion in our KO model using histological, physiological, neuroendocrinological, and behavioral measures. Our findings indicate that GHSR deletion in rats is not only associated with a lack of response to ghrelin, but also associated with decreases in daily food consumption and body growth, and increases in BAT. This GHSR KO Wistar rat model provides a novel tool for studying the role of the ghrelin system in obesity and in a wide range of medical and neuropsychiatric disorders. PMID- 29453462 TI - GQ-11: A new PPAR agonist improves obesity-induced metabolic alterations in LDLr /- mice. AB - BACKGROUND: Obesity and insulin resistance/diabetes are important risk factors for cardiovascular diseases and demand safe and efficacious therapeutics. OBJECTIVE: To assess the effects of a new thiazolidine compound-GQ-11-on obesity and insulin resistance induced by a diabetogenic diet in LDL receptor-deficient (LDLr-/-) mice. METHODS: Molecular docking simulations of GQ-11, PPARalpha and PPARgamma structures were performed. Male C57BL/6J LDLr-/- mice fed a diabetogenic diet for 24 weeks were treated with vehicle, GQ-11 or pioglitazone or (20 mg/kg/day) for 28 days by oral gavage. Glucose tolerance test, insulin, HOMA-IR, adipokines (leptin, adiponectin) and the lipid profile were assessed after treatment. Adipose tissue was analysed by X-ray analysis and morphometry; gene and protein expression were evaluated by real-time PCR and western blot, respectively. RESULTS: GQ-11 showed partial agonism to PPARgamma and PPARalpha. In vivo, treatment with GQ-11 ameliorated insulin sensitivity and did not modify subcutaneous adipose tissue and body weight gain. In addition, GQ-11 restored adipokine imbalance induced by a diabetogenic diet and enhanced Glut-4 expression in the adipose tissue. Improved insulin sensitivity was also associated with lower levels of MCP-1 and higher levels of IL-10. Furthermore, GQ-11 reduced triglycerides and VLDL cholesterol and increased HDL-cholesterol by upregulation of Apoa1 and Abca1 gene expression in the liver. CONCLUSION: GQ-11 is a partial/dual PPARalpha/gamma agonist that demonstrates anti-diabetic effects. Additionally, it improves the lipid profile and ameliorates chronic inflammation associated with obesity in atherosclerosis-prone mice. PMID- 29453463 TI - Impact of gastric emptying and small intestinal transit on blood glucose, intestinal hormones, glucose absorption in the morbidly obese. AB - OBJECTIVE: This study evaluated gastric emptying (GE) and small intestinal (SI) transit in people with morbid obesity and their relationships to glycaemia, incretin hormones, and glucose absorption METHODS: GE and caecal arrival time (CAT) of a mixed meal were assessed in 22 morbidly obese (50.2 +/- 2.5 years; 13 F:9 M; BMI: 48.6 +/- 1.8 kg/m2) and 10 lean (38.6 +/- 8.4 years; 5 F:5 M; BMI: 23.9 +/- 0.7 kg/m2) subjects, using scintigraphy. Blood glucose, plasma 3-O methylglucose, insulin, glucagon, glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) were measured. Insulin sensitivity and resistance were also quantified RESULTS: When compared with lean subjects, GE (t50: 60.7 +/- 6.5 vs. 41.1 +/- 7.3 min; P = 0.04) and CAT (221.5 +/- 9.8 vs. 148.0 +/- 7.1 min; P = 0.001) of solids were prolonged in morbid obesity. Postprandial rises in GIP (P = 0.001), insulin (P = 0.02), glucose (P = 0.03) and 3-O-methylglucose (P = 0.001) were less. Whereas GLP-1 increased at 45 mins post-prandially in lean subjects, there was no increase in the obese (P = 0.04). Both fasting (P = 0.045) and postprandial (P = 0.012) plasma glucagon concentrations were higher in the obese CONCLUSIONS: GE and SI transit are slower in the morbidly obese, and associated with reductions in postprandial glucose absorption, and glycaemic excursions, as well as plasma GIP and GLP-1. PMID- 29453464 TI - Dietitian-led lifestyle modification programme for obese Chinese adolescents with non-alcoholic fatty liver disease: a randomized controlled study. AB - BACKGROUND: The prevalence of non-alcoholic fatty liver disease (NAFLD) in children is increasing. This study evaluated the efficacy of a dietitian-led lifestyle modification programme (D-LMP) to reduce NAFLD in obese adolescents. METHODS: Subjects with intra-hepatic triglyceride content (IHTC) equal to or greater than 5% diagnosed by proton-magnetic resonance spectroscopy (1H-MRS) were enroled and randomly assigned to either the D-LMP intervention or conventional paediatrician-led consultation (P-CON) group. Subjects in the P-CON group received usual care consisting of a consultation by a paediatrician with the child and parents every 16 weeks. Intention-to-treat analysis was used for data analysis. RESULTS: Fifty-two subjects were recruited, with 26 in each group. After the initiation phase (at week-16), there was a greater difference in the change in the IHTC and BMI z-score in the D-LMP group (P = 0.029 and <0.001, respectively) and there was a decrease in dietary intake of fat content (P = 0.019). After 52 weeks of the maintenance phase, both groups had reductions of IHTC to 2-3% and there was no intergroup difference in the rate of reduction. During the maintenance phase, parents' involvement was minimal in the D-LMP group, with only three parents accompanying their children to attend the dietitian sessions. In contrast, over 90% of the parents in the P-CON group regularly accompanied their children to attend the consultations suggesting the possibility that regular parental and paediatrician involvement may contribute to increasing awareness on fatty liver complications. Multivariate analysis showed that only reduction in body fat remained as an independent factor associated with remission of NAFLD at the end of both study phases. CONCLUSIONS: A dietitian-led lifestyle modification intervention reduced IHTC, BMI z-score and body fat in obese Chinese adolescents with NAFLD. To sustain the effect of this intervention, regular parental and paediatrician involvement may be important. PMID- 29453465 TI - Screening of potential adipokines identifies S100A4 as a marker of pernicious adipose tissue and insulin resistance. AB - BACKGROUND: Adipokines are peptides secreted from white adipose tissue (WAT), which have been linked to WAT dysfunction and metabolic complications of obesity. We set out to identify novel adipokines in subcutaneous WAT (sWAT) linked to insulin resistance (IR). METHODS: Gene expression was determined by microarray and qPCR in obese and non-obese subjects with varying degree of IR. WAT-secreted and circulating protein levels were measured by ELISA. RESULTS: In sWAT of 80 obese women discordant for IR, 44 genes encoding potential adipose-secreted proteins were differentially expressed. Among these, merely two proteins, S100A4 and MXRA5 were released from sWAT in a time-dependent manner (criterion for true adipokines) but only the circulating levels of S100A4 were higher in IR. In two additional cohorts (n = 29 and n = 56), sWAT S100A4 secretion was positively and BMI-independently associated with IR (determined by clamp or HOMA-IR), ATP-III risk score and adipocyte size (hypertrophy). In non-obese (n = 20) and obese subjects before and after bariatric surgery (n = 21), circulating and sWAT secreted levels were highest in the obese and normalized following weight loss. Serum S100A4 concentrations were higher in subjects with type 2 diabetes. S100A4 sWAT expression associated positively with genes involved in inflammation/extracellular matrix formation and inversely with genes in metabolic pathways. Although S100A4 was expressed in both stromal cells and adipocytes, only the expression in adipocytes associated with BMI. CONCLUSIONS: S100A4 is a novel adipokine associated with IR and sWAT inflammation/adipocyte hypertrophy independently of BMI. Its value as a circulating marker for dysfunctional WAT and IR needs to be validated in larger cohorts. PMID- 29453466 TI - Effects of Intrathecal Dexmedetomidine as an Adjuvant to Hyperbaric Bupivacaine for Spinal Anaesthesia in Adults Undergoing Elective Infra-umbilical Surgery. AB - INTRODUCTION: Various adjuvants to local anaesthetic are used to improve quality and duration of spinal anaesthesia. Dexmedetomidine, a novel alpha-2 adrenergic agonist, has been proposed to augment local anaesthetic effects. This study aims to investigate effects of intrathecal Dexmedetomidine on duration of analgesia and duration of sensory block during spinal anaesthesia. METHODS: In this randomized double-blind study 38 patients were allocated into each of two groups. Otherwise healthy patients (18 to 75 years) scheduled for inguinal hernia repair or vaginal hysterectomy were included. For spinal anaesthesia, Group A received 2.5 ml hyperbaric Bupivacaine 0.5%, whereas Group B received five micrograms intrathecal Dexmedetomidine in addition. Characteristics of sensory and motor blocks, duration of analgesia, analgesic requirements, and side effects were studied for 24 hours. Student's t-test for quantitative variables and Chi- squared test for qualitative variables were used for statistical analysis. RESULTS: Duration of analgesia was prolonged in Group B (326 min +/-91) as compared to 217 min +/-98 in Group A (P value <0.05). Sensory and motor block durations were significantly prolonged in Group B. Time taken to reach significant peak sensory block level was earlier in Group B. Significant reductions in incidence of visceral pain, shivering and analgesic requirements were observed in Dexmedetomidine group, without increased need of medications for altered hemodynamic parameters. CONCLUSIONS: Dexmedetomidine as an intrathecal adjuvant to hyperbaric Bupivacaine in spinal anaesthesia prolongs duration of analgesia and sensory block with minimal adverse effects. PMID- 29453467 TI - Loading Dose only versus Standard Dose Magnesium Sulfate Seizure Prophylaxis in Severe Pre-eclamptic Women. AB - INTRODUCTION: Magnesium sulfate is the drug of choice for prevention of seizures in the pre-eclamptic woman. There is no agreement in the published randomized trials regarding the optimal time to initiate magnesium sulfate, the dose to use (both loading and maintenance) as well as the duration of therapy. The objective of this study is to determine whether magnesium sulfate prophylaxis is needed for up to 24 hours postpartum in all patients with severe pre-eclampsia for the prevention of seizure. METHODS: It is a randomized controlled trial conducted on 60 pregnant women with severe preeclampsia randomized into standard dose and loading dose only regimen. RESULTS: Out of 30 cases in each group 1 (3.3%) patient in standard regimen and 2 (6.7%) patients in loading dose only developed seizure. The occurrence of seizure is not significant statistically. In both regimens, there was no maternal mortality. Total of 3 patients needed MICU care and 12 patient developed maternal complications. MgSO4 toxicities were seen only in standard dose regimen that is in 17 (56.7%) of the patients. The median number of IM injections of MgSO4 received in standard dose regimen was 8+/-2.176. In standard dose regimen 73.3 percent baby were alive whereas in case of loading dose only regimen 93.3 percent of baby were alive after 48 hours of delivery. CONCLUSIONS: Single dose of magnesium sulfate is equally effective as standard dose regimen in terms of seizure prophylaxis in severe pre eclamptic women, with added advantage of reduced maternal toxicity and better neonatal outcome. PMID- 29453468 TI - Prevention of Shivering during Spinal Anesthesia: Comparison between Tramadol, Ketamine and Ondansetron. AB - INTRODUCTION: Shivering is an unpleasant experience after spinal anesthesia. We conducted this study to evaluate the efficacy of ondansetron, ketamine and tramadol for prevention of shivering. METHODS: In this randomized controlled study, 120 patients aged 18-65 years of American Society of Anesthesiologist (ASA) physical status I and II undergoing various surgical procedures were included and allocated alternately to one of the 4 groups; Normal saline (Group1), Ondansetron 4mg (Group2), Ketamine 0.25mg/kg (Group3) and Tramadol 0.5mg/kg (Group4). Incidence of shivering, effect on hemodynamics, nausea, vomiting, sedation and emergence reactions were recorded. Data was analyzed using SPSS (The Statistical Package for Social Sciences) version 20.0 software. RESULTS: The patients were comparable in terms of demographic variables, baseline temperature, type of surgery, median level of sensory blockade, duration of surgery and anesthesia. Shivering was present in 17 (56.7%), 5 (16.7%), 3 (10%) and 3 (10%) patients respectively in Group 1, 2, 3 and 4 which was statistically significant when compared to Group 1 (P=0.00) The odds of NS and ondansetron, NS and ketamine, NS and tramadol was 6.53, 11.76 and 11.76 respectively which showed that study drugs were effective in preventing shivering. None of the patients were sedated in Group 1 and 2. Mild to moderate sedation was present in Group 3 and 4 (P=0.00). None of the patients had drug related adverse reactions. CONCLUSIONS: Prophylactic use of ondansetron, low doses of ketamine and tramadol is effective in preventing shivering post spinal anesthesia without untoward effects. PMID- 29453469 TI - Demographic and Clinical Profile in Patients with Liver Cirrhosis in a Tertiary Care Hospital in Central Nepal. AB - INTRODUCTION: Liver cirrhosis is an important health problem worldwide and is a common disease in Nepal. The profile of cirrhosis may vary due to different factors. This study was undertaken to see the demographic and clinical profiles of patients with cirrhosis of liver attending a tertiary care hospital in Central Nepal. METHODS: Six hundred patients with clinical features, laboratory and sonological findings suggestive of chronic liver dysfunction and endoscopic evidence of portal hypertension were included in the study. Their demographic and clinical profile, endoscopic findings, outcomes during hospitalization were studied. Ethical approval was taken from Institutional Review Committee of College of Medical Sciences. SPSS 20 was used for statistical analysis. RESULTS: The mean age of subjects was 54+/-11.84 years with 435 males (72.5%) and 165 (27.5%) females. Majority of 203 (33.8%) patients were from Mongol ethnicity followed by 127 (21.2%) Khas. Two hundred and twenty (36.6%) were farmers followed by 169 (28.2%) retired personnel. A total of 338 (56.4 %) patients were from rural areas. The commonest aetiology of cirrhosis was chronic alcohol consumption and seen in 552 (92%) patients. Abdominal distension was commonest presenting sign and observed in 561 (93.5%) patients. Ascites seen in 555 (92.5%) patients was the commonest complication followed by UGI bleed in 326 (54.3%) patients. Gastro-oesophageal varices observed in 345 (57.5%) patients, was the most common endoscopic finding followed by portal gastropathy, peptic ulcer and erosive mucosal diseases. In patient mortality was noted in 92 (15.3 %) patients. CONCLUSIONS: This study highlights the burden of cirrhosis, usually caused by chronic alcohol consumption in Central Nepal. Majority of subjects were male, middle aged, farmers, from rural areas and predominantly observed in some ethnicity like Mongols. Cirrhotic patients usually Keywords: cirrhosis of liver; complications; endoscopy. PMID- 29453470 TI - Nerve Conduction and Heart Rate variability in Patients with Hypothyroidism at a Tertiary Care Centre in Eastern Nepal. AB - INTRODUCTION: Thyroid hormone effects on many organs including central and peripheral nervous systems. However, these hormones do not affect all systems/organs to a similar extent. Thus, we conducted this study to explore the effect of thyroid hormones on somatic nervous system assessed by Nerve conduction study and cardiac autonomic activity assessed by heart rate variability. METHODS: The study included newly diagnosed hypothyroid patients and healthy controls. In all subjects NCS were performed in median, ulnar, tibial and sural nerves using Nihonkohden machine Cardiac autonomic control was assessed using Short-term Heart Rate Variability and parameters were analyzed by Time Domain and Frequency Domain methods. RESULTS: Both the groups were comparable in term of age, Body Mass Index, Pulse Rate, Systolic Blood Pressure and Diastolic Blood Pressure. Sensory parameters of NCS showed significant decrease in left median nerve SNAP amplitude (38.24+/-10.23 Vs 31.59+/-14.06, P=0.048) and nerve conduction velocity of bilateral median nerve in hypothyroid patients. In motor parameters of NCS, onset latencies of bilateral median nerves and right ulnar nerve were significantly increased in hypothyroid patients. All Time Domain measures of HRV and Frequency Domain measures; LF Power, HF Power and Total Power were significantly decreased (P<0.05) in hypothyroid patients. These HRV parameters are indicators of parasympathetic activity. CONCLUSIONS: In newly diagnosed hypothyroid patients, especially median nerve functions (both sensory and motor) and parasympathetic activity were decreased. It reflects that in hypothyroidism both autonomic nervous system and other somatic nerves are not affected in a similar extent. PMID- 29453471 TI - Significance of Non-Invasive Markers as Predictor of Esophageal Varices in Liver Cirrhosis. AB - INTRODUCTION: Upper gastro-intestinal endoscopy remains the gold standard for screening for esophageal varices but it has its own limitations. It is an invasive, expensive and uncomfortable procedure and needs clinical expertise. Accordingly, this study was conducted to establish the role of non-invasive markers for prediction of esophageal varices in liver cirrhosis. METHODS: A hospital based descriptive cross-sectional study was carried out in Liver unit of National Academy of Medical Sciences, Bir Hospital, from October 2016 to September 2017. Complete blood count, liver function test, liver ultrasound and upper gastro-intestinal endoscopy were done for all patients to detect esophageal varices and to correlate with different non-invasive markers. RESULTS: Total 191 patients of liver cirrhosis were studied after exclusion. Platelet count of 92082.00+/-43435.83/mm3 and spleen size of 144.21+/-10.71 mm was found to be good predictors of presence of EV (P<=0.001). Significant association between Child Turcotte-Pugh class and presence of varices was observed (P<=0.001). AST/ALT ratio with cutoff value of 1.415 showed sensitivity of 82.4% and specificity of 36.4%. APRI at a cutoff value of 1.3 showed a sensitivity of 83.2% and specificity of 50%. CONCLUSIONS: Platelet count, spleen size and Child-Turcotte Pugh class are good predictors of presence of esophageal varices in patients with liver cirrhosis. AST/ALT ratio and APRI score are not good substitutes for upper gastro-intestinal endoscopy. PMID- 29453472 TI - Prevalence of Hepatitis D Among Patients with Hepatitis B Viral Infection Attending a Tertiary Care Centre of Nepal. AB - INTRODUCTION: Worldwide there is variation in prevalence of Hepatitis D viral infection. Superinfection and co infection with hepatitis B viral infection is known to occur in 15-20 million people. METHODS: This was a descriptive cross sectional hospital based study carried out in NAMS, Bir hospital, Kathmandu, Nepal from period of January 2017 to June 2017. Consecutive patients of chronic hepatitis B viral infection of HBsAg positive with more than two-time upper normal limit of ALT were enrolled and tested for HDV IgG. RESULTS: Forty patients were enrolled during study period. Mean age was 30.9+/-12.2 years. Males were 28 (70%) and females 12 (30%). Most of the patients were asymptomatic for HBV infection 32 (80%). HBeAg negative chronic hepatitis was most commonly present in 31 (77.5%). Family history of Hepatitis B viral infection was seen in 7 (17.5%) and sexual promiscuity in 5 (12.5%) as the mode of acquisition of hepatitis B viral infection. HBcIgM was positive in three patients with mean HBV DNA of 4.97x105+/-4.5x105 IU/ml in HBeAg positive group. HDV IgG was negative in all patients. CONCLUSIONS: Coinfection and superinfection of hepatitis D virus were found to be uncommon at Bir hospital, Nepal. PMID- 29453473 TI - Prehospital Events in ST- Elevation Myocardial Infarction Undergoing Primary Angioplasty. AB - INTRODUCTION: Pre-hospital delay includes time from onset of symptoms of myocardial infarction till arrival to emergency room of the hospital. This defines time from symptom onset to first medical contact and first medical contact to emergency room. This study aims to study the prehospital events and determining factors in patients undergoing primary angioplasty. METHODS: This was a cross sectional study in Shahid Gangalal National Heart Centre for three months. Timings of chest pain, first medical contact time, transfer time to hospital and overall pre-hospital time for PCI and risk factors were analysed. RESULTS: There were 79 cases with 66 (83.5%) males and 13 (16.5%) females with mean age 56+/-11.2 years. Risk factors were 60 (75.9%), smoking, 47 (59.5%) hypertension, 25 (31.6%) diabetes, 22 (27.8%) dyslipidaemia and 16 (20.3%) heart failure. Chest pain was maximum in 5 to 9 AM. The median prehospital delay was 300 minutes (5.0 hours) of which symptom to first medical contact was 165 minutes and first medical contact to hospital was 80 minutes. The longer median prehospital delay for hypertension, diabetes, female and age >=50 years and the shorter for male, age less than 50 years, dyslipidemia and heart failure, though not statistically significant. Private transport was the preferred from symptom to first medical contact and ambulance for first medical contact to emergency room. Patients received in ER had aspirin 72 (91.1%), atorvastatin 54 (68.4%) and double anti-platelets 45 (57%). CONCLUSIONS: Chest pain was common in morning and the prehospital delay can be minimized by improving time from symptom to first medical contact and first medical contact to Emergency room. PMID- 29453474 TI - Fingerprints as an Alternative Method to Determine ABO and Rh Blood Groups. AB - INTRODUCTION: Blood grouping is conventionally done with invasive method by taking blood samples. The objective of this study is to determine blood group with uninvasive procedure by taking fingerprints of the participants and know the associations between their fingerprints and blood groups. METHODS: Seven hundred participants of both genders with no any age limitation from Manipal Teaching Hospital and Manipal College of Medical Sciences were randomly selected. The blood grouping was done by cross reacting blood sample with the antibodies. The fingerprints were taken with the help of stamp pad imprinting the finger ridges over A4 size white papers. The loop, whorl and arch patterns were studied. RESULTS: O+ve blood group 224 (32%) was most prevalent among 700 participants. The loop pattern was highly distributed 3708 (53%) in all blood groups except in A-ve blood group with highest distribution of whorl 20 (40%). The mean comparisons of specific fingerprint in total and also in individual fingers with different ABO and ABO-Rh blood groups showed no any statistical association with P>0.05. However, the loop distribution in individual finger was highest in right middle finger (M) of B-ve blood group 5 (10%). The whorl distribution in individual finger was highest in right index (I), left thumb (T) and left ring (R) fingers of AB+ve blood group 20 (5.5% each). Similarly, the arch distribution was highest in right index fingers of A-ve blood group 3 (6%). CONCLUSIONS: The mean comparison of different fingerprints with ABO and Rh blood groups showed no significant statistical association concluding fingerprints cannot be used for blood grouping. PMID- 29453475 TI - Basal Cell Carcinoma in Cases with or without Xeroderma Pigmentosum. AB - INTRODUCTION: Basal cell carcinoma is the most common form of cancer in humans and comprises the vast majority of skin cancers. It predominantly affects fair skinned individuals, and its incidence is rapidly increasing. The objective of the study is to identify the epidemiology, its topography and different histological subtypes of basal cell carcinoma in patients with or without Xeroderma Pigmentosum. METHODS: A cross-sectional descriptive study was conducted at Manipal Teaching Hospital, Pokhara from Jan 2009 to Dec 2016. Ethical approval was taken from MEMG/IRC/GA. The study included patients with a confirmed diagnosis of basal cell carcinoma irrespective of their age and sex. RESULTS: This study showed 77 individuals with 91 biopsies of BCC including 5 cases of Xeroderma Pigmentosum. The predominant histological subtype was nodular with 41 (53.94%) cases, followed by the 14 (18.42%) cases of pigmented and 10 (13.15%) cases baso-squamous subtype. The most frequent sites of involvement were the head and neck, with predominance in the nasal and orbital region. The mean age was 57.68 years but the basal cell carcinoma in cases of Xeroderma Pigmentosum was seen more in younger age groups. There were 43 (55.84 %) male patients and 34 (44.16 %) female patients with a male to female ratio of 1.26:1. CONCLUSIONS: Nodular and pigmented varieties were the most frequent subtypes with nose being the commonest site of involvement. Basal cell carcinomas in cases of Xeroderma Pigmentosum were noted in younger age group with multiple lesions. PMID- 29453476 TI - Postoperative Outcome in Patients with Pulmonary Hypertension Undergoing Elective Non-Cardiac Surgery. AB - INTRODUCTION: The impact of pulmonary artery hypertension on post-operative outcome in elective, non-cardiac surgery is incompletely understood. This study was designed to evaluate the post-operative outcome of patients undergoing elective, non-cardiac surgery with and without pulmonary hypertension. METHODS: The study was conducted in an inner-city hospital in Bronx, New York. A retrospective chart review was conducted on all patients who underwent elective, non- cardiac surgery from January 2000 to December 2010 and had echocardiogram within 30 days of surgery. Patients with systolic pressure of >=35mm of Hg as estimated by echocardiogram were enrolled. Case matched peers with normal pulmonary pressures served as controls. Post-operative outcomes were compared between the two groups. RESULTS: A total of 66 patients were analysed, 33 cases and 33 controls. All patients were followed up to 30-day post-surgery. Heart failure, myocardial infarction, arrhythmia, stroke, delayed extubation and deaths were measured in both the groups. There were two deaths in the control group while there were three deaths in pulmonary hypertension group (statistically not significant, P >0.05). A total of three patients in pulmonary hypertension group had adverse outcome (one had a major arrhythmia, one had delayed extubation (>24 hours) and one had stroke). Whereas two patients in control group had adverse outcome (one had delayed extubation (>24 hours) and one had major arrhythmia). CONCLUSIONS: Pulmonary hypertension does not affect the post-operative outcome in the first 30 days for elective non-cardiac surgery. PMID- 29453477 TI - Effects of Bilateral Nasal Packing on Oxygen Saturation and Blood Pressure. AB - INTRODUCTION: Nasal packing is one of the most common rhinological procedures in ENT practice exerting local in nose and systemic effects. Systemic effects may be due to poor sleep quality, respiratory difficulty, decreased oxygen saturation, circulatory problems and toxic shock syndrome which can threaten the life of a person.The study was done to investigate the effect on bilateral nasal packing on blood oxygen saturation and blood pressure changes. METHODS: A cross-sectional prospective study was undertaken in Kathmandu Medical College from January 2017 to June 2017. The ethical approval was taken from institutional review committee of KMC and verbal consent was taken from each patient. Thirty patients were included in the study by simple randomized sampling. The association between nasal packing and oxygen saturation and blood pressure was done using ANNOVA and Fisher Exact test. P value of <0.005 was considered statistically significant. SPSS version 20 for windows OS was used for analysis. RESULTS: Blood oxygen saturation on four different days was compared using ANNOVA and paired sample tests. It showed a significant dip on the day of bilateral nasal packing compared to other readings (P value <0.001). Likewise, systolic and diastolic blood pressures showed a significant rise on the day of bilateral nasal packing compared to readings on other days (P value <0.001). CONCLUSIONS: Bilateral nasal packing can lead to significant rise in systolic and diastolic blood pressure and a dip in blood oxygen saturation. Thus care has to be taken while performing bilateral nasal packing in normal patients but much more in high risk patients.

AB - INTRODUCTION: Sinonasal polyposis is one of the commonest causes of nasal obstruction. Surgical management is treatment of choice. Microdebrider offers more advantage to conventional instruments. We aimed to find out outcome using microdebrider versus conventional instruments in endoscopic sinus surgery of sinonasal polyposis. METHODS: The cross sectional descriptive study carried out in patients aged 13 years and above with diagnosis of sinonasal polyposis. Total of 51 patients were operated on the right side with microdebrider and left side with conventional instruments. Postoperatively each patient assessed for nasal obstruction subjectively and by endoscopic examination to look for mucosal oedema, synechiae and recurrence at 4 weeks and 8 weeks postoperatively. RESULTS: The incidence of mucosal oedema in microdebrider and conventional instruments at 4 weeks and 8 weeks was statistically not significant with P value 0.089, 0.322 respectively. The incidence of synechiae in conventional group was more than microdebrider 1 (2%) versus 4 (7.8%) at 4 weeks follow up but the difference was statistically not significant (P value 0.773). There were 2 (3.9%) recurrences in microdebrider group and 3 (5.8%) recurrences in conventional group with P value 0.532. CONCLUSIONS: Use of microdebrider offered fewer incidences of synechiae and recurrence. But we couldn't find statistical advantage over conventional instruments. PMID- 29453479 TI - Blood Pressure and its Association with Body Mass Index Among the People Attending in a Hospital. AB - INTRODUCTION: Systolic and diastolic hypertension has been increasing trend and different factors are associated such as body mass index, diabetes etc. Obesity and overweight are generally associated with high blood pressure. This study aims to identify the prevalence of blood pressure level and its association to body mass index among people attending in civil service hospital, Kathmandu. METHODS: A cross-sectional descriptive study was conducted among all 1002 study subjects aged above 20 years. Information were obtained from people coming for Master health check-up during study period. Blood pressure and weight were taken by WHO certified tool. RESULTS: Half of the respondents were overweight and obese. Prevalence of systolic and diastolic hypertension was found to be 171 (17.1%) and 310 (30.9%) respectively. There is significant difference between body mass index to sex. Females are 1.5 times more likely to have high blood pressure who have high body mass index. Age group (40-59) years are more than two times likely to have overweight, systolic and diastolic blood pressure than other age group. Systolic blood pressure is more than six times more likely to be high in 60+ age group. But it is only 2.6 times in diastolic blood pressure and in body mass index, it is reduced to 1.4 times but it was still statistically significant. Overweight people are 1.4 and 1.6 times more likely to have high systolic and diastolic BP than another category. CONCLUSIONS: Half of the respondents were overweight and obese. Male had high overweight and obesity than female. Overweight people more likely to have high systolic and diastolic BP than others. PMID- 29453480 TI - Limited Open Reduction and Percutaneous Plate Osteosynthesis - Alternative Option to Minimally Invasive Plate Osteosynthesis in Management of Distal Tibia Fractures. AB - INTRODUCTION: The management of distal tibia fracture is challenging because of the limited soft tissue coverage and poor vascularity around the bone in that area. Minimally invasive percutaneous plate osteosynthesis is a novel technique in this regard but needs fluoroscopy. In unavailability of fluoroscopy or its technical malfunction, limited open reduction percutaneous plate osteosynthesis becomes useful. The aim of this study is to compare the outcomes of distal tibia fractures treated by LORPPO and MIPPO techniques in terms of duration of hospital stay, full weight bearing, union time and complications. METHODS: Twenty-two cases of closed distal tibia fractures without articular involvement or comminution operated at Koshi Zonal Hospital, Nepal from March 2014 to May 2016 were included in this study. Total 11cases of which were treated by MIPPO whereas other 11 cases were treated by LORPPO. MIPPO technique was done only when the fluoroscopy was available. RESULTS: In MIPPO, the average age of the patients were 43.72 (range 23-65) years, hospital stay mean duration 8.45 (range 6-12) days, full weight-bearing walking was started in 11.27 (range 9-15) weeks and average radiological union time was 21.25 (range 18-28) weeks. In LORPPO, the mean age was 46.36 (range 25-70)years, hospital stay mean 11.81 (range 10-15) days, full weight bearing walking mean 10.63 (range 9-15) weeks and average radiological union time was 23.0 (range 19-27) weeks. CONCLUSIONS: The outcomes are comparatively similar for both the techniques. LORPPO could be an alternative to MIPPO in the management of distal tibia fractures. PMID- 29453481 TI - Ventilator-Associated Pneumonia and Role of Nurses in Its Prevention. AB - Ventilator-associated pneumonia (VAP) is one of the most frequent nosocomial infections among ventilated patients in ICUs, associated with an increase in days of ICU stay, morbidity, and mortality. Its prevention is a significant concern in every hospital. Most of the interventions and prevention strategies are part of routine nursing care. Nurses have different vital roles such as care provider, manager, educator, coordinator, and evaluator in preventing VAP. Lack of knowledge of infection prevention and proper nursing care among nurses may become a barrier in adhering to evidence-based guidelines for preventing ventilator associated pneumonia. This study will help nurses to know about VAP and its prevention in detail so that they can apply the knowledge in clinical practice. Understanding pathophysiology of VAP, its risk factors, and care bundle is vital for the proper prevention and treatment of VAP. There must be specific protocols, strategies and active surveillance in every ICU regarding the care bundle.

AB - Identification of victims in a disaster is a challenging process and requires use of both primary and secondary identifiers. Development of teeth is one of the routinely used methods of age estimation and helps in establishing deceased biological profile. Two children who lost their lives in 2014 in Nepal Airlines crash, were looked for the dental developmental status. One of the children had primary dentition, while the other had mixed dentition. This helped us in estimating age of these individuals reconciled with the chronological age provided by the relatives. This led to the identification of both the children, thus, emphasizing teeth as important means of identification in any disaster. PMID- 29453483 TI - Chorioangioma of Placenta. AB - Chorioangioma of placenta is the commonest benign tumour of the placenta. It consists of a benign angioma arising from chorionic tissue. We report a case of placental chorioangioma which was diagnosed in the post partum period in a patient with polyhydramnios who went into preterm labor and delivered a premature baby. PMID- 29453484 TI - Late Presentation of Post Diphtheritic Myocarditis in a 15-year Male. AB - A 15-year old male patient presented to us with dyspnoea for four days. He had a history of fever, pseudo-membranous tonsillitis and cervical adenopathy twenty five days prior to the presentation. On examination and laboratory investigations, he had features suggestive of myocarditis with biventricular failure. There was no reliable history of immunisation and he had a positive history of contact. He was planned for anti-diphtheria toxin but before the anti toxin could be initiated, the patient succumbed to refractory cardiogenic shock. This was a rare case of late onset diphtheritic myocarditis in an unimmunised adult. With the advent of universal immunisation, there has been a significant decline in the incidence but there is still some road to cover. PMID- 29453485 TI - Oral Squamous Papilloma of Edentulous Mouth Interfering with Denture Retention. AB - Soft tissue overgrowths inside oral cavity can present with wide range of clinical manifestations and some of them can asymptomatic. Oral squamous papilloma is one of that asymptomatic lesion described in the literature with extremely low virulence and infectivity rate. Soft tissue overgrowths can sometimes interfere with denture retention. Here we report a case of squamous papilloma in a 60 years old edentulous female who presented with loss of denture retention. PMID- 29453486 TI - Immune System and Kidney Transplantation. AB - The immune system recognises a transplanted kidney as foreign body and mounts immune response through cellular and humoral mechanisms leading to acute or chronic rejection, which ultimately results in graft loss. Over the last five decades, there have been significant advances in the understanding of the immune responses to transplanted organs in both experimental and clinical transplant settings. Modulation of the immune response by using immunosuppressive agents has led to successful outcomes after kidney transplantation. The paper provides an overview of the general organisation and function of human immune system, immune response to kidney transplantation, and the current practice of immunosuppressive therapy in kidney transplantation in the United Kingdom. PMID- 29453487 TI - Significant differences between manufacturer and surgeon in the accuracy of final component size prediction with CT-based patient-specific instrumentation for total knee arthroplasty. AB - PURPOSE: Patient-specific instrumentation (PSI) for total knee arthroplasty (TKA) may improve component sizing. Little has been reported about accuracy of the default plan created by the manufacturer, especially for CT-based PSI. The goal of this study was to evaluate the reliability of this plan and the impact of the surgeon's changes on the final accuracy of the guide sizes. METHODS: Forty-five patients eligible for primary TKA were prospectively enrolled. The planned implant sizes were prospectively recorded from the initial manufacturer's proposal and from the final plan adjusted in light of the surgeon's evaluation; these two sizes where then compared to the actually implanted sizes. Fisher's exact test was used to test differences for categorical variables. Agreement between pre-operative plans and final implant was evaluated with the Bland-Altman method. RESULTS: The manufacturer's proposal differed from the final implant in 9 (20.0%) femoral and 23 (51.1%) tibial components, while the surgeon's plan in 6 (13.3%, femoral) and 12 (26.7%, tibial). Modifications in the pre-operative plan were carried out for five (11.1%) femoral and 23 (51.1%) tibial components (p = 0.03). Appropriate modification occurred in 22 (88.0%) and 19 (76.0%) cases of femoral and tibial changes. The agreement between the manufacturer's and the surgeon's pre-operative plans was poor, especially with regard to tibial components. CONCLUSION: The surgeon's accuracy in predicting the final component size was significantly different from that of the manufacturer and changes in the initial manufacturer's plan were necessary to get an accurate pre-operative plan of the implant sizes. CLINICAL RELEVANCE: Careful evaluation of the initial manufacturer's plan by an experienced knee surgeon is mandatory when planning TKA with CT-based PSI. LEVEL OF EVIDENCE: II. PMID- 29453488 TI - No evidence for combining cartilage treatment and knee osteotomy in osteoarthritic joints: a systematic literature review. AB - PURPOSE: To assess whether the combination of HTO and cartilage treatment produced an additional clinical benefit compared to HTO alone. The secondary aim was to identify if there was any difference among different cartilage procedures in terms of healing potential and clinical outcome. METHODS: A systematic review of the literature was performed on PubMed database by three independent observers according to the following inclusion criteria: clinical reports of any level of evidence, written in the English language, with no time limitation, about HTO associated with cartilage surgical and injective treatment, including surveys reporting clinical, radiological, or second-look outcomes at any follow-up time. RESULTS: The database search identified 1956 records: 21 studies were included for the final analysis, for a total of 1068 patients; 10 case series and 11 comparative studies. While overall good results were reported in the case series, the analysis of the comparative studies showed less uniform results. Among the eight studies investigating HTO with cartilage surgical procedures, improved tissue regeneration was found in 5/8 studies, whereas a clinical improvement was reported only in two studies. Three studies on HTO combination with injective treatment showed better tissue regeneration and clinical benefit. CONCLUSIONS: Literature presents low-quality studies, with only few heterogeneous comparative papers. While surgical treatments targeting only the cartilage layer did not achieve clinical improvements, injective treatments targeting the overall joint environment showed promising findings. This prompts further research towards the development of treatments able to improve knee osteotomies outcomes. However, until new evidence will prove otherwise, there is no indication for a combined cartilage treatment in routine clinical practice. LEVEL OF EVIDENCE: Level IV. PMID- 29453489 TI - Fascia iliaca blockade with the addition of liposomal bupivacaine vs. plain bupivacaine for perioperative pain management following hip arthroscopy. AB - PURPOSE: A newer formulation of bupivacaine, encapsulated within carrier molecules, has garnered attention for its role in providing extended post operative analgesia. The purpose was to evaluate the addition of liposomal bupivacaine to fascia iliaca blockade during hip arthroscopy. METHODS: Retrospective cohort study of patients undergoing hip arthroscopy with a pre operative fascia iliaca blockade with either liposomal bupivacaine (Group 1; 266mg + 20 cc 0.5% plain bupivacaine) or bupivacaine (Group 2; 40 cc 0.25% plain bupivacaine). All patients received standardized pre-operative oral pain medications. The primary outcome was the defense veteran pain rating scale (DVPRS). Secondary outcomes included duration of hospital admission, PACU opioid use, PACU pain scores, and duration of nerve blockade. RESULTS: Thirty-eight males and 30 females, mean age of 33 years (range 14-56). There was no difference in pre-operative DVPRS between the groups (n.s.). There was no difference in post operative DVPRS pain scores at POD0 (3.7 vs. 3.9, n.s.), POD1 (4.2 vs. 3.8, n.s.), POD2 (4.2 vs. 3.7, n.s.), POD3 (3.9 vs. 3.7, n.s.) or POD14 (2.2 vs. 2.4, n.s.). Group 1 trended towards longer mean total hospital admission time (872 vs. 822 min, n.s.), and greater mean morphine equivalents administered in the PACU (33 vs. 29 mg, n.s.). 68% of patients in group 1 reported continued anterior thigh numbness at POD3, compared to 34% in group 2 (p = 0.008). CONCLUSIONS: Despite the advertised benefits of prolonged post-operative analgesia using liposomal bupivacaine, there were no significant differences in post-operative pain scores or PACU opioid consumption. Our results support that acceptable pain scores are successfully achieved at all time periods with the use of multimodal analgesia including fascia iliaca blockade despite the type of pain medication administered. LEVEL OF EVIDENCE: III. PMID- 29453490 TI - Goal-directed reaching: the allocentric coding of target location renders an offline mode of control. AB - Reaching to a veridical target permits an egocentric spatial code (i.e., absolute limb and target position) to effect fast and effective online trajectory corrections supported via the visuomotor networks of the dorsal visual pathway. In contrast, a response entailing decoupled spatial relations between stimulus and response is thought to be primarily mediated via an allocentric code (i.e., the position of a target relative to another external cue) laid down by the visuoperceptual networks of the ventral visual pathway. Because the ventral stream renders a temporally durable percept, it is thought that an allocentric code does not support a primarily online mode of control, but instead supports a mode wherein a response is evoked largely in advance of movement onset via central planning mechanisms (i.e., offline control). Here, we examined whether reaches defined via ego- and allocentric visual coordinates are supported via distinct control modes (i.e., online versus offline). Participants performed target-directed and allocentric reaches in limb visible and limb-occluded conditions. Notably, in the allocentric task, participants reached to a location that matched the position of a target stimulus relative to a reference stimulus, and to examine online trajectory amendments, we computed the proportion of variance explained (i.e., R2 values) by the spatial position of the limb at 75% of movement time relative to a response's ultimate movement endpoint. Target directed trials performed with limb vision showed more online corrections and greater endpoint precision than their limb-occluded counterparts, which in turn were associated with performance metrics comparable to allocentric trials performed with and without limb vision. Accordingly, we propose that the absence of ego-motion cues (i.e., limb vision) and/or the specification of a response via an allocentric code renders motor output served via the 'slow' visuoperceptual networks of the ventral visual pathway. PMID- 29453493 TI - Altered prepulse inhibition of the acoustic startle response in BDNF-deficient mice in a model of early postnatal hypoxia: implications for schizophrenia. AB - The brain-derived neurotrophic factor (BDNF) is a major proliferative agent in the nervous system. Both BDNF-deficiency and perinatal hypoxia represent genetic/environmental risk factors for schizophrenia. Moreover, a decreased BDNF response to birth hypoxia was associated with the disease. BDNF expression is influenced by neuronal activity and environmental conditions such as hypoxia. Thus, it may partake in neuroprotective and reparative mechanisms in acute or chronic neuronal insults. However, the interaction of hypoxia and BDNF is insufficiently understood and the behavioral outcome unknown. Therefore, we conducted a battery of behavioral tests in a classical model of chronic early postnatal mild hypoxia (10% O2), known to significantly impair brain development, in BDNF-deficient mice. We found selective deficits in measures associated with sensorimotor gating, namely enhanced acoustic startle response (ASR) and reduced prepulse inhibition (PPI) of ASR in BDNF-deficient mice. Unexpectedly, the alterations of sensorimotor gating were caused only by BDNF-deficiency alone, whereas hypoxia failed to evoke severe deficits and even leads to a milder phenotype in BDNF-deficient mice. As deficits in sensorimotor gating are present in schizophrenia and animal models of the disease, our results are of relevance regarding the involvement of BDNF in its pathogenesis. On the other hand, they suggest that the effect of perinatal hypoxia on long-term brain abnormalities is complex, ranging from protective to deleterious actions, and may critically depend on the degree of hypoxia. Therefore, future studies may refine existing hypoxia protocols to better understand neurodevelopmental consequences associated with schizophrenia. PMID- 29453492 TI - Application of physiologically based pharmacokinetic modeling to the prediction of drug-drug and drug-disease interactions for rivaroxaban. AB - PURPOSE: Rivaroxaban is a direct oral anticoagulant with a large inter-individual variability. The present study is to develop a physiologically based pharmacokinetic (PBPK) model to predict several scenarios in clinical practice. METHODS: A whole-body PBPK model for rivaroxaban, which is metabolized by the cytochrome P450 (CYP) 3A4/5, 2J2 pathways and excreted via kidneys, was developed to predict the pharmacokinetics at different doses in healthy subjects and patients with hepatic or renal dysfunction. Hepatic clearance and drug-drug interactions (DDI) were estimated by in vitro in vivo extrapolation (IVIVE) based on parameters obtained from in vitro experiments. To validate the model, observed concentrations were compared with predicted concentrations, and the impact of special scenarios was investigated. RESULTS: The PBPK model successfully predicted the pharmacokinetics for healthy subjects and patients as well as DDIs. Sensitivity analysis shows that age, renal, and hepatic clearance are important factors affecting rivaroxaban pharmacokinetics. The predicted fold increase of rivaroxaban AUC values when combined administered with the inhibitors such as ketoconazole, ritonavir, and clarithromycin were 2.3, 2.2, and 1.3, respectively. When DDIs and hepatic dysfunction coexist, the fold increase of rivaroxaban exposure would increase significantly compared with one factor alone. CONCLUSIONS: Our study using PBPK modeling provided a reasonable approach to evaluate exposure levels in special patients under special scenarios. Although further clinical study or real-life experience would certainly merit the current work, the modeling work so far would at least suggest caution of using rivaroxaban in complicated clinical settings. PMID- 29453491 TI - Does hearing aid use affect audiovisual integration in mild hearing impairment? AB - There is converging evidence for altered audiovisual integration abilities in hearing-impaired individuals and those with profound hearing loss who are provided with cochlear implants, compared to normal-hearing adults. Still, little is known on the effects of hearing aid use on audiovisual integration in mild hearing loss, although this constitutes one of the most prevalent conditions in the elderly and, yet, often remains untreated in its early stages. This study investigated differences in the strength of audiovisual integration between elderly hearing aid users and those with the same degree of mild hearing loss who were not using hearing aids, the non-users, by measuring their susceptibility to the sound-induced flash illusion. We also explored the corresponding window of integration by varying the stimulus onset asynchronies. To examine general group differences that are not attributable to specific hearing aid settings but rather reflect overall changes associated with habitual hearing aid use, the group of hearing aid users was tested unaided while individually controlling for audibility. We found greater audiovisual integration together with a wider window of integration in hearing aid users compared to their age-matched untreated peers. Signal detection analyses indicate that a change in perceptual sensitivity as well as in bias may underlie the observed effects. Our results and comparisons with other studies in normal-hearing older adults suggest that both mild hearing impairment and hearing aid use seem to affect audiovisual integration, possibly in the sense that hearing aid use may reverse the effects of hearing loss on audiovisual integration. We suggest that these findings may be particularly important for auditory rehabilitation and call for a longitudinal study. PMID- 29453494 TI - Population genetic data of Investigator HDplex markers in Han population from Southern China. AB - Allele frequencies and forensic statistical parameters for 12 STRs contained in the Investigator HDplex Kit (D2S1360, D3S1744, D4S2366, D5S2500, SE33, D6S474, D7S1517, D8S1132, D10S2325, D12S391, D18S51, and D21S2055) were estimated from a sample of 503 unrelated individuals from the Guangdong Han population of South China. No significant departure from the Hardy-Weinberg equilibrium or genetic linkage disequilibrium was observed (after Bonferroni correction). The expected heterozygosity ranged from 0.6411 to 0.9414. The allele frequencies in Guangdong Han significantly differed from that in Shanghai Han, Korea, Northern Italian, Swedish, Dutch, Somalia, and Argentinean populations at 2 to 12 loci. The markers included in the kit have highly polymorphic information that could be used for forensic DNA analysis as potential tools for differentiating Han population from other populations in the world. PMID- 29453495 TI - Comparison of concentrations of drugs between blood samples with and without fluoride additive-important findings for Delta9-tetrahydrocannabinol and amphetamine. AB - Fluoride is a common stabilizing agent in forensic toxicology to avoid the frequent problem of degradation of drugs in blood samples especially described for cocaine. In cases only samples with addition of fluoride are available, it is a crucial question if also concentrations of common drugs other than cocaine (amphetamines, opiates and cannabinoids) are affected by fluoride. So far, there are only rare literature data available on discrepant results especially for Delta9-tetrahydrocannabinol (THC). In this study, comparative analysis of positive tested paired routine plasma/serum samples (n = 375), collected at the same time point (one device with and one without fluoride), was carried out with special focus on cannabinoids. Samples were measured with validated routine liquid chromatography-tandem mass spectrometry methods for THC, 11-hydroxy-THC (THC-OH), 11-nor-9-carboxy-THC (THC-COOH), cocaine, benzoylecgonine, ecgonine methyl ester, morphine, codeine, amphetamine, methamphetamine, 3,4 methylenedioxymethamphetamine, 3,4-methylenedioxyamphetamine, and 3,4 methylenedioxyethylamphetamine, and results were statistically evaluated. Beside the expected stabilization effect on cocaine and the consequently reduced concentration of ecgonine methyl ester in fluoride samples, benzoylecgonine was elevated compared to respective samples without fluoride. Most importantly, new findings were significantly reduced mean concentrations of THC (- 17%), THC-OH (- 17%), and THC-COOH (- 22%) in fluoride samples. Mean amphetamine concentration was significantly higher in samples with the additive (+ 6%). For the other amphetamine type of drugs as well as for morphine and codeine, no significant differences could be seen. Whenever specified thresholds have been set, such as in most European countries, the use of different blood sample systems may result in a motorist being differently charged or prosecuted. The findings will support forensic toxicologists at the interpretation of results derived from fluoride stabilized blood samples. PMID- 29453496 TI - Influence of surface treatment on the performance of silorane-based composite resin in class I restorations: a randomized clinical trial. AB - OBJECTIVES: The aim of this study was to evaluate the clinical performance of silorane-based composite restorations applied after different surface treatments. MATERIALS AND METHODS: This controlled and randomized clinical trial included 26 patients with class I restoration indications. The teeth were randomly assigned to the following treatments: control 1/G1, silorane specific self-etching adhesive (P90 self-etch primer and bond) + silorane-based composite resin (FiltekTM P90 low shrink posterior restorative); G2, 37% phosphoric acid + silorane specific self-etching adhesive + silorane-based composite resin; G3, blasting with aluminum oxide + silorane specific self-etching adhesive + silorane based composite resin; and control 2/G4, self-etching adhesive (AdperTM SE Plus self-etch adhesive) + dimethacrylate-based composite resin (FiltekTM P60 posterior restorative). The clinical performance was evaluated at baseline and after 1 year. RESULTS: A total of 141 restorations were made and evaluated. For all clinical criteria evaluated, no significant difference was found between the surface treatments at baseline and after 1 year (p > 0.05). After 1 year, only the group with 37% phosphoric acid + silorane specific self-etching adhesive (G2) showed a significant reduction in marginal adaptation (p < 0.05). CONCLUSION: In general, all surface treatments showed an adequate clinical performance for silorane-based composite resin in class I restorations. However, a reduction in the marginal adaptation after 1 year was found when additional phosphoric acid etching was used prior to silorane specific self-etching adhesive. CLINICAL RELEVANCE: The use of phosphoric acid etching prior to specific self-etching adhesive can adversely affect the marginal adaptation of silorane-based restorations. PMID- 29453497 TI - Bone mineralization and vascularization in bisphosphonate-related osteonecrosis of the jaw: an experimental study in the rat. AB - OBJECTIVES: Pathogenesis of bisphosphonate-related osteonecrosis of the jaws (BRONJ) is not fully explained. An antiangiogenic effect of bisphosphonates (BPs) or an altered bone quality have been advocated. The aims of the present study were to analyze alveolar mandibular vascularization and bone quality in rats with BRONJ. MATERIALS AND METHODS: Thirty-eight Sprague-Dawley rats were randomized into two groups: zoledronic acid (ZA), n = 27, and control (CTRL) n = 11. The ZA group received a weekly IV injection of ZA (100 MUg/kg) during 10 weeks. The CTRL group received saline. After 6 weeks, extraction of the right mandibular molars was performed. Rats were sacrificed after 14 weeks. Microtomography characterized bone lesions and vascularization after injection of a radio-opaque material. Raman microspectroscopy evaluated bone mineralization. RESULTS: Fifty-five percent of ZA rats presented bone exposure and signs of BRONJ. None sign was found at the left hemimandible in the ZA group and in the CTRL group. Vascular density appeared significantly increased in the right hemimandibles of the CTRL group compared to the left hemimandibles. Vascularization was reduced in the ZA group. A significantly increased of the mineral-to-amide ratio was found in the alveolar bone of ZA rats by Raman microspectroscopy. CONCLUSIONS: In a rat model of BRONJ, microtomography evidenced osteonecrosis in BRONJ. Raman spectroscopy showed an increased mineralization. Vascularization after tooth extraction was impaired by ZA. CLINICAL RELEVANCE: Prolonged BP administration caused an increase in the mineralization and a quantitative reduction of the vascularization in the alveolar bone; both factors might be involved concomitantly in the BRONJ pathophysiology. PMID- 29453498 TI - Seed priming with iron and zinc in bread wheat: effects in germination, mitosis and grain yield. AB - Currently, the biofortification of crops like wheat with micronutrients such as iron (Fe) and zinc (Zn) is extremely important due to the deficiencies of these micronutrients in the human diet and in soils. Agronomic biofortification with Fe and Zn can be done through different exogenous strategies such as soil application, foliar spraying, and seed priming. However, the excess of these micronutrients can be detrimental to the plants. Therefore, in the last decade, a high number of studies focused on the evaluation of their phytotoxic effects to define the best strategies for biofortification of bread wheat. In this study, we investigated the effects of seed priming with different dosages (1 mg L-1 to 8 mg L-1) of Fe and/or Zn in germination, mitosis and yield of bread wheat cv. 'Jordao' when compared with control. Overall, our results showed that: micronutrient dosages higher than 4 mg L-1 negatively affect the germination; Fe and/or Zn concentrations higher than 2 mg L-1 significantly decrease the mitotic index and increase the percentage of dividing cells with anomalies; treatments performed with 8 mg L-1 of Fe and/or 8 mg L-1 Zn caused negative effects in germination, mitosis and grain yield. Moreover, seed priming with 2 mg L-1 Fe + 2 mg L-1 Zn has been shown to be non-cytotoxic, ensuring a high rate of germination (80%) and normal dividing cells (90%) as well as improving tillering and grain yield. This work revealed that seed priming with Fe and Zn micronutrients constitutes a useful and alternative approach for the agronomic biofortification of bread wheat.

PMID- 29453499 TI - Screening for gene-environment (G*E) interaction using omics data from exposed individuals: an application to gene-arsenic interaction. AB - Identifying gene-environment interactions is a central challenge in the quest to understand susceptibility to complex, multi-factorial diseases. Developing an understanding of how inter-individual variability in inherited genetic variation alters the effects of environmental exposures will enhance our knowledge of disease mechanisms and improve our ability to predict disease and target interventions to high-risk sub-populations. Limited progress has been made identifying gene-environment interactions in the epidemiological setting using existing statistical approaches for genome-wide searches for interaction. In this paper, we describe a novel two-step approach using omics data to conduct genome wide searches for gene-environment interactions. Using existing genome-wide SNP data from a large Bangladeshi cohort study specifically designed to assess the effect of arsenic exposure on health, we evaluated gene-arsenic interactions by first conducting genome-wide searches for SNPs that modify the effect of arsenic on molecular phenotypes (gene expression and DNA methylation features). Using this set of SNPs showing evidence of interaction with arsenic in relation to molecular phenotypes, we then tested SNP-arsenic interactions in relation to skin lesions, a hallmark characteristic of arsenic toxicity. With the emergence of additional omics data in the epidemiologic setting, our approach may have the potential to boost power for genome-wide interaction research, enabling the identification of interactions that will enhance our understanding of disease etiology and our ability to develop interventions targeted at susceptible sub populations. PMID- 29453500 TI - Isolated greater tuberosity fractures of the proximal humerus: anatomy, injury patterns, multimodality imaging, and approach to management. AB - The greater tuberosity is an important anatomic structure and its integrity is important for shoulder abduction and external rotation. Isolated fractures of the greater tuberosity are often subtle and may not be detected on initial radiographs. Clinically, these patients display symptoms which mimic a full thickness rotator cuff tear. It is important to differentiate these two entities, as their treatment is different (typically nonsurgical management for minimally displaced fractures versus rotator cuff repair for acute full thickness rotator cuff tears). When greater tuberosity fractures are significantly displaced and allowed to heal without anatomic reduction, they can lead to impingement. This article will review greater tuberosity anatomy and function, as well as the clinical presentation and multimodality imaging findings of greater tuberosity fractures. Imaging optimization, pitfalls, and clinical management of these fractures will also be discussed. PMID- 29453502 TI - Parenting Wisely Six Months Later: How Implementation Delivery Impacts Program Effects at Follow-Up. AB - We evaluated the effectiveness of the Parenting Wisely (PW) program 6 months post intervention and assessed differences based on delivery format. Using a quasi experimental design, parents (N = 311) participated in the PW program in one of five formats (i.e., parents-only intensive workshop, parents-only 5-week group, parents and adolescents 5-week group, parent and adolescent online, and parent only online format). An additional 53 parents served as a comparison group. We used the McMaster Family Assessment Device, the Child Behavior Checklist, and the Violent Behavior Checklist to measure family functioning, parenting, and adolescent behavior. Relative to the comparison group, at 6 month follow-up parents who participated in PW reported increases in confidence in their parenting skills, decreases in conflicts with their adolescents, and decreases in adolescent externalizing and violent behavior. Mechanisms of change analyses supported the conceptual model that program effects were related to child behavior changes by influencing positive parenting and decreasing negative family dynamics. PW effectiveness did not vary substantially by delivery format, except for the intensive workshop format, which was less effective than other formats. These findings extend research on PW to include evidence of sustained program effects on adolescent externalizing and violent behaviors in an ethnically diverse, socioeconomically disadvantaged sample. Study findings are relevant to agencies and clinicians who are seeking to implement an evidence-based, flexible parent-training program.

AB - The PCBH model of integrated care blends behavioral health professionals into the primary care team, thereby enhancing the scope of primary care and expanding the range of services provided to the patient. Despite promising evidence in support of the model and a growing number of advocates and practitioners of PCBH integration, current reimbursement policies are not always favorable. As the nation's healthcare system transitions to value-based payment models, new financing strategies are emerging which will further support the viability of PCBH integration. This article provides an overview of the infrastructure necessary to support PCBH practice; reviews the current PCBH funding landscape; discusses how emerging trends in healthcare financing are impacting the model; and provides a vision for the viability of the PCBH model within the value-based financing of our healthcare system in the future.

AB - This study aimed to examine the direct and indirect effects of hope on health related quality of life (HRQoL) via anxiety of children/adolescents with cancer. We proposed to test if the mediation model was moderated by the child/adolescent's treatment status. The participants were 211 children/adolescents diagnosed with cancer, divided into two clinical groups according to treatment status: 97 patients on-treatment and 114 off-treatment. Self-reported questionnaires measured the youths' hope, anxiety, and HRQoL perceptions. The results revealed that children/adolescents on- and off-treatment only differed in levels of HRQoL, with a more compromised HRQoL found for the on treatment group. Hope was positively associated with HRQoL, directly and indirectly via anxiety reduction. Moreover, only the association between anxiety and HRQoL was moderated by clinical group, revealing stronger associations for on treatment patients. Findings highlight the importance of hope as a decisive resource in pediatric cancer adaptation, which may be strategically targeted in psycho-oncological interventions. PMID- 29453506 TI - Illness Beliefs, Treatment Beliefs and Information Needs as Starting Points for Patient Information: The Evaluation of an Intervention for Patients with Depression. AB - Patients with depression are often dissatisfied with disease- and therapy-related information. The objective of this study was to evaluate an intervention that applied the Common Sense Model to the provision of information during inpatient rehabilitation for patients with depression. The intervention was evaluated in a sequential control group design. Analyses of covariance were used to assess differences between the control and intervention groups. Changes with respect to illness and treatment beliefs (personal control, treatment control, coherence and concerns about medicines), satisfaction with information about medicines, illness and rehabilitation, and depressive burden were selected as primary outcome measures. We observed significant between-group differences indicating the intervention group's superiority in terms of satisfaction with information regarding medicines. However, the two groups' changes during rehabilitation did not differ in terms of the other outcomes. The intervention resulted in patients judging that their medication information needs had been more thoroughly fulfilled than those patients who received care-as-usual information. However, the intervention did not prove to be effective when the other outcome variables are considered. Taken together and bearing in mind the limitations of our study particularly the non-randomised design-our results should be replicated in a randomised controlled trial.

AB - This manuscript is an outgrowth of an invited panel presentation at the national Association for Psychologists in Academic Health Centers Conference in 2017 on Interprofessional Education (IPE). IPE is a structured and transformative educational strategy designed to provide active learning experiences where trainees from diverse healthcare professions gain shared content knowledge plus collaboration skills as they learn about, from, and with each other. Collaboration skills include understanding professional role distinctions and overlap, effective team-based communication, shared values/ethics and respect for each other's expertise, and teamwork dynamics. It is increasingly important to expand training beyond the intraprofessional activities in which psychology trainees engage to prepare them to participate in interprofessional collaborative care. As healthcare systems move to team-based collaborative practice and value based reimbursement models, the profession of psychology needs leaders at every academic health center to facilitate the design and/or implementation of IPE activities. The panel of psychologists presented roles that psychologists play in IPE institutional program design and implementation, graduate training programs, and the perspectives of an early career psychologist and psychology trainee. Opportunities and challenges are highlighted, culminating in a call to action. Psychologists must embrace their identity as health professionals and engage their learners in IPE so that the emerging cognitive schemata of healthcare that is developed includes the profession of psychology. Otherwise, healthcare teams and health professionals will not understand the value, roles, or potential contributions of psychologists in enhancing patient care outcomes, ultimately jeopardizing psychologists' referrals, involvement in healthcare delivery, and career opportunities. PMID- 29453508 TI - Refractory gastric antral ulcers without Helicobacter pylori infection and non steroidal anti-inflammatory drugs. AB - Herein, we describe a rare case of refractory gastric antral ulcers. A woman in her 50 s was admitted to Nagoya City University Hospital with epigastric pain after being diagnosed with gastric antral submucosal tumor at another hospital. Findings from esophagogastroduodenoscopy and endoscopic ultrasound examination revealed that the lesion was a gastric ulcer. The patient had no Helicobacter pylori infection and no recent history of using non-steroidal anti-inflammatory drugs. On the basis of these findings, we diagnosed this as a case of refractory gastric antral ulcer (RGAU). RGAU is considered a new disease concept and detailed analyses are expected in the future. PMID- 29453509 TI - Critical thresholds for eventual extinction in randomly disturbed population growth models. AB - This paper considers several single species growth models featuring a carrying capacity, which are subject to random disturbances that lead to instantaneous population reduction at the disturbance times. This is motivated in part by growing concerns about the impacts of climate change. Our main goal is to understand whether or not the species can persist in the long run. We consider the discrete-time stochastic process obtained by sampling the system immediately after the disturbances, and find various thresholds for several modes of convergence of this discrete process, including thresholds for the absence or existence of a positively supported invariant distribution. These thresholds are given explicitly in terms of the intensity and frequency of the disturbances on the one hand, and the population's growth characteristics on the other. We also perform a similar threshold analysis for the original continuous-time stochastic process, and obtain a formula that allows us to express the invariant distribution for this continuous-time process in terms of the invariant distribution of the discrete-time process, and vice versa. Examples illustrate that these distributions can differ, and this sends a cautionary message to practitioners who wish to parameterize these and related models using field data. Our analysis relies heavily on a particular feature shared by all the deterministic growth models considered here, namely that their solutions exhibit an exponentially weighted averaging property between a function of the initial condition, and the same function applied to the carrying capacity. This property is due to the fact that these systems can be transformed into affine systems. PMID- 29453510 TI - Next-generation metabolic screening: targeted and untargeted metabolomics for the diagnosis of inborn errors of metabolism in individual patients. AB - The implementation of whole-exome sequencing in clinical diagnostics has generated a need for functional evaluation of genetic variants. In the field of inborn errors of metabolism (IEM), a diverse spectrum of targeted biochemical assays is employed to analyze a limited amount of metabolites. We now present a single-platform, high-resolution liquid chromatography quadrupole time of flight (LC-QTOF) method that can be applied for holistic metabolic profiling in plasma of individual IEM-suspected patients. This method, which we termed "next generation metabolic screening" (NGMS), can detect >10,000 features in each sample. In the NGMS workflow, features identified in patient and control samples are aligned using the "various forms of chromatography mass spectrometry (XCMS)" software package. Subsequently, all features are annotated using the Human Metabolome Database, and statistical testing is performed to identify significantly perturbed metabolite concentrations in a patient sample compared with controls. We propose three main modalities to analyze complex, untargeted metabolomics data. First, a targeted evaluation can be done based on identified genetic variants of uncertain significance in metabolic pathways. Second, we developed a panel of IEM-related metabolites to filter untargeted metabolomics data. Based on this IEM-panel approach, we provided the correct diagnosis for 42 of 46 IEMs. As a last modality, metabolomics data can be analyzed in an untargeted setting, which we term "open the metabolome" analysis. This approach identifies potential novel biomarkers in known IEMs and leads to identification of biomarkers for as yet unknown IEMs. We are convinced that NGMS is the way forward in laboratory diagnostics of IEMs. PMID- 29453511 TI - Developing new age-specific prostate-specific antigen thresholds for testing for prostate cancer. AB - PURPOSE: To examine whether age-related reference ranges for "normal" prostate specific antigen (PSA) change (determined in men without prostate cancer) can be used to identify men at high risk of having prostate cancer. METHODS: Subjects were men aged 50-69 years with PSA < 10 ng/mL from the UK-based Prostate Testing for cancer and Treatment (ProtecT) study. Men with prostate cancer were categorized as high or low risk of progression (Low risk: Gleason score <= 6 and stage T1-T2a; High risk: Gleason score 7-10 or stage T2C). Men without prostate cancer were those with no histological confirmation of prostate cancer. Previously developed longitudinal reference ranges for normal age-related PSA change were used to calculate an age-specific PSA threshold. We compared the ability of our age-specific PSA threshold to discriminate between high- and no/low-risk prostate cancer with that of two existing thresholds: (i) threshold of PSA = 3 ng/ml for all ages; (ii) National Institute of Clinical Excellence (NICE) guidelines dependent on age-group thresholds (age 50-59: PSA = 3 ng/mL; age 60-70: PSA = 4 ng/mL; age >= 70: PSA = 5 ng/mL). RESULTS: We included 823 men with high-risk prostate cancer and 80,721 men with no/low-risk prostate cancer. A threshold of PSA = 3 ng/ml for all ages identified more high-risk prostate cancers, recommending biopsy in 9.8% of men, of which 10.3% (n = 823) had high risk prostate cancer. Using the NICE guidelines as the threshold for biopsy, 6.9% men were recommended for biopsy, of which 11.9% (n = 668) had high-risk prostate cancer. Using the new age-specific threshold for biopsy, 2.3% men were recommended for biopsy, of which 15.2% (n = 290) had high-risk prostate cancer. The age-specific threshold identified fewer high-risk prostate cancers, but fewer men received unnecessary biopsy. CONCLUSION: There is no benefit to using reference ranges for "normal" PSA that change with age nor the age-specific thresholds suggested by the NICE guidelines. While the age-varying thresholds are more discriminatory, too many high-risk cancers are missed. PMID- 29453513 TI - Simultaneous cell disruption and lipid extraction of wet aurantiochytrium sp. KRS101 using a high shear mixer. AB - Microalgae are regarded as a promising source of biofuels, and the concept of a microalgae-based biorefinery has attracted increasing attention in recent years. From an economic perspective, however, the process remains far from competitive with fossil fuels. This is particularly true of lipid extraction, due in part to the energy-intensive drying step. As a result, wet extraction methods have been studied as an economic alternative. In the present study, a novel extraction approach which utilizes high shear stress mixing was adopted and demonstrated for simultaneous lipid extraction and cell disruption to enable the retrieval of lipids directly from concentrated wet biomass. When a high shear mixer (HSM) was used to extract lipid from a dense biomass (> 350 g/L) of the oleaginous algae Aurantiochytrium sp., it exhibited a yield of esterifiable lipids which exceeded 80% in 10 min at 15,000 rpm with various solvent types. The HSM was found to improve the lipid yields substantially with solvents less miscible with either lipids or water, such that the range of Hansen solubility parameters for the usable solvents became 3.3 times wider (14.9-26.5 MPa1/2). The HSM, which appeared effectively to loosen the water barrier that prevents solvent molecules from penetrating through the cell envelope, was found to be more efficient with hexane, hexane/isopropanol, and ethanol, all of which showed nearly identical lipid yields compared to the dry extraction process. The HSM can, indeed, offer a powerful mechanical means of lipid extraction with non-polar and less toxic solvents from wet biomass. PMID- 29453512 TI - Global and Japanese regional variations in radiologist potential workload for computed tomography and magnetic resonance imaging examinations. AB - PURPOSE: To investigate the global variation in radiologist potential workload for CT and MRI examinations, and the regional variation in potential workload and extent of radiologists' involvement in CT and MRI examinations in Japan. METHODS: "Radiologist potential workload" was defined as the annual number of CT plus MRI examinations divided by the total number of diagnostic radiologists. The extent of radiologists' involvement was measured as the proportion of CT and MRI examinations to which "Added-fees for Radiological Managements on Imaging-studies (ARMIs)" were applied among eligible examinations. Maximum variation was computed as the ratio of the highest-to-lowest values among the countries or Japanese prefectures. RESULTS: The radiologist potential workload in Japan was 2.78-4.17 times higher than those in other countries. A maximum prefecture-to-prefecture variation was 3.88. The average percentage of CT plus MRI examinations with ARMI applied was 43.3%, with a maximum prefecture-to-prefecture variation of 3.97. Prefectures with more radiologists tended to have a higher extent of radiologists' involvement. CONCLUSIONS: Japan had a far greater radiologist potential workload compared with other countries, with a large regional variation among prefectures. Prefectures with more radiologists tended to have a higher extent of radiologists' involvement in CT and MRI examinations. PMID- 29453514 TI - Prevalence and Determinants of Vitamin D Deficiency Among the Overweight and Obese Singaporeans Seeking Weight Management Including Bariatric Surgery: a Relationship with Bone Health. AB - PURPOSE: Low vitamin D status is prevalent worldwide and has been linked to a variety of pathologies including obesity in adults. The severity of vitamin D deficiency amongst the overweight and obese Singaporeans is not well documented. The purpose of this prospective observational study was to assess the prevalence and determinants of vitamin D deficiency in a multi-ethnic Asian population referred for weight management, including those seeking bariatric surgery. MATERIALS AND METHODS: This was a cross-sectional study conducted among 111 consecutive subjects referred to a single institution weight management service in Singapore. The data collected included their anthropometric data, body mass index (BMI), body fat percentage, waist circumference, 25-hydroxyvitamin D [25(OH)D] and other bone turnover markers. RESULTS: The average BMI among the 111 subjects was 40.1 +/- 8.2 kg/m2 and mean age of 40 +/- 10 years. Vitamin D deficiency was found in 75.7% of the population. There was a significant negative association of vitamin D with adiposity markers including BMI (r = - 0.31), body fat percentage (r = - 0.34) and waist circumference (r = - 0.26). Predictors of vitamin D deficiency included age > 50 years, female gender, waist circumference and body fat percentage. CONCLUSION: Vitamin D deficiency is prevalent among this target population in Singapore regardless of ethnicity. In particular, the elderly, females, those with larger waist circumference and body fat percentage were significantly associated with lower serum 25(OH)D level. Hence, routine screening for the overweight and obese subjects in multi-ethnic Singapore seeking weight management is indicated.

AB - BACKGROUND: The aim of the present study was to evaluate the safety and efficacy of autologous, micro-fragmented and minimally manipulated adipose tissue injection associated closure of the internal opening in promoting healing of complex anal fistula. METHODS: A pilot study was conducted on patients referred to our center with anal fistula, from April 2015-December 2016. Inclusion criteria were age over 16 years old and a diagnosis of complex anal fistula according to the American Gastroenterological Association classification The patients were divided into 2 groups; the "first time group" (Group I) in which micro-fragmented adipose tissue injection with closure of the internal opening was the first sphincter-saving procedure, and the "recurrent group" (Group II) consisting of patients who had failed prior sphincter-saving procedures. The procedure was carried out 4-6 weeks after seton placement. Follow-up visits were scheduled at 7 days, and 1, 3, 6 and 12 months after surgery. Fistula healing was defined as the closure of the internal and external openings without any discharge. RESULTS: Out of 47 patients with complex transsphincteric anal fistula, 19 met the inclusion criteria and were selected to undergo the procedure. Twelve of these patients (Group I) had micro-fragmented adipose tissue injection as first-line treatment, and 7 (Group II) had failed previous sphincter saving procedures. The mean operative time was 55 +/- 6 min (range 50-70 min). The mean postoperative pain score measured with the visual analog pain scale was 2 +/- 1.4 (range 0-4). No intraoperative difficulties related to the use of the kit were recorded. There were no cases of postoperative fever or abdominal sepsis related to the procedure and no post-treatment perianal bleeding or impaired anal continence. Only 3 cases of minor abdominal wall hematoma that did not require any treatment and 1 case of perianal abscess were observed. Patients were evaluated for a mean follow-up time of 9 +/- 3.1 months (range 3-12 months). The overall healing rate was 73.7, 83.3% for Group I and 57.1% for Group II. CONCLUSIONS: The injection of autologous, micro-fragmented and minimally manipulated adipose tissue associated with closure of the internal opening is a safe, feasible and reproducible procedure and may enhance complex anal fistula healing.

AB - B7H6 is emerging as a promising tumor antigen that is known to be expressed on a wide array of tumors and is reported to stimulate anti-tumor responses from the immune system. As such, B7H6 presents a good target for tumor-specific immunotherapies. B7H6-specific chimeric antigen receptors (CAR) based on a murine antibody showed successful targeting and elimination of tumors expressing B7H6. However, mouse single chain variable fragments (scFvs) have the potential to induce host anti-CAR responses that may limit efficacy, so human scFvs specific for B7H6 were selected by yeast surface display. In this study, we validate the functionality of these human scFvs when formatted into chimeric antigen receptors. The data indicate that T cells expressing these B7H6-specific human scFvs as CARs induced potent anti-tumor activity in vitro and in vivo against tumors expressing high amounts of B7H6. Importantly, these human scFv-based CARs are sensitive to changes in B7H6 expression which may potentially spare non-tumor cells that express B7H6 and provides the foundation for future clinical development. PMID- 29453517 TI - Probable Diagnosis of a Patient with Niemann-Pick Disease Type C: Managing Pitfalls of Exome Sequencing. AB - Here, we present a case of a 31-year-old man with progressive cognitive decline, ataxia, and dystonia. Extensive laboratory, radiographic, and targeted genetic studies over the course of several years failed to yield a diagnosis. Initial whole exome sequencing through a commercial laboratory identified several variants of uncertain significance; however, follow-up clinical examination and testing ruled each of these out. Eventually, repeat whole exome sequencing identified a known pathogenic intronic variant in the NPC1 gene (NM_000271.4, c.1554-1009G>A) and an additional heterozygous exonic variant of uncertain significance in the NPC1 gene (NM_000271.4, c.2524T>C). Follow-up biochemical testing was consistent with a diagnosis of probable Niemann-Pick disease Type C (NP-C). This case illustrates the potential of whole exome sequencing for diagnosing rare complex neurologic diseases. It also identifies several potential common pitfalls that must be navigated by clinicians when interpreting commercial whole exome sequencing results. PMID- 29453519 TI - TriCurin, a synergistic formulation of curcumin, resveratrol, and epicatechin gallate, repolarizes tumor-associated macrophages and triggers an immune response to cause suppression of HPV+ tumors. AB - Our earlier studies reported a unique potentiated combination (TriCurin) of curcumin (C) with two other polyphenols. The TriCurin-associated C displays an IC50 in the low micromolar range for cultured HPV+ TC-1 cells. In contrast, because of rapid degradation in vivo, the TriCurin-associated C reaches only low nano-molar concentrations in the plasma, which are sub-lethal to tumor cells. Yet, injected TriCurin causes a dramatic suppression of tumors in TC-1 cell implanted mice (TC-1 mice) and xenografts of Head and Neck Squamous Cell Carcinoma (HNSCC) cells in nude/nude mice. Here, we use the TC-1 mice to test our hypothesis that a major part of the anti-tumor activity of TriCurin is evoked by innate and adaptive immune responses. TriCurin injection repolarized arginase1high (ARG1high), IL10high, inducible nitric oxide synthaselow (iNOSlow), IL12low M2-type tumor-associated macrophages (TAM) into ARG1low, IL10low, iNOShigh, and IL12high M1-type TAM in HPV+ tumors. The M1 TAM displayed sharply suppressed STAT3 and induced STAT1 and NF-kB(p65). STAT1 and NF-kB(p65) function synergistically to induce iNOS and IL12 transcription. Neutralizing IL12 signaling with an IL12 antibody abrogated TriCurin-induced intra-tumor entry of activated natural killer (NK) cells and Cytotoxic T lymphocytes (CTL), thereby confirming that IL12 triggers recruitment of NK cells and CTL. These activated NK cells and CTL join the M1 TAM to elicit apoptosis of the E6+ tumor cells. Corroboratively, neutralizing IL12 signaling partially reversed this TriCurin mediated apoptosis. Thus, injected TriCurin elicits an M2->M1 switch in TAM, accompanied by IL12-dependent intra-tumor recruitment of NK cells and CTL and elimination of cancer cells. PMID- 29453520 TI - Evaluation of a Comprehensive Oral Health Services Program in School-Based Health Centers. AB - Objectives In 2011, the Maternal and Child Health Bureau, within the Health Resources and Services Administration, awarded a 4-year grant to increase access to and assure the delivery of quality oral health preventive and restorative services to children. The grant was awarded to organizations serving high-need communities through school-based health centers (SBHCs). This article describes an independent evaluation investigating program efficacy, integration, and sustainability. Methods Program process and outcomes data were gathered from interim and final reports. Interviews with key informants were conducted by phone, and analyzed in NVivo qualitative software. Results Students had great need for comprehensive services: on average, 45% had dental caries at enrollment. Enrollment increased from 5000 to more than 9700, and the percent receiving preventive services increased from 58 to 88%. Results of the analytically weighted linear regression show statistically significant increases in the proportion of enrollees who had their teeth cleaned in the past year (t(4) = 5.19, beta = 8.85, p < 0.05) and those receiving overall preventive services (t(4) = 13.52, beta = 10.93, p < 0.01). Grantees integrated into existing programs using clear, consistent, and open communication. Grantees sustained the full suite of services beyond the grant period by increasing billing and insurance claims while still offering free and reduced-cost services to those uninsured or otherwise unable to pay. Conclusions for Practice This project demonstrates that access to comprehensive oral health care for children can be expanded through SBHCs. State Title V Block Grant and other similar federal initiatives can learn from the strategic approaches used to overcome challenges in the school-based environment. PMID- 29453521 TI - Safety and feasibility of breast lesion localization using magnetic seeds (Magseed): a multi-centre, open-label cohort study. AB - PURPOSE: Wire localization has several disadvantages, notably wire migration and difficulty scheduling the procedure close to surgery. Radioactive seed localization overcomes these disadvantages, but implementation is limited due to radiation safety requirements. Magnetic seeds potentially offer the logistical benefits and transcutaneous detection equivalence of a radioactive seed, with easier implementation. This study was designed to evaluate the feasibility and safety of using magnetic seeds for breast lesion localization. METHODS: A two centre open-label cohort study to assess the feasibility and safety of magnetic seed (Magseed) localization of breast lesions. Magseeds were placed under radiological guidance into women having total mastectomy surgery. The primary outcome measure was seed migration distance. Secondary outcome measures included accuracy of placement, ease of transcutaneous detection, seed integrity and safety. RESULTS: Twenty-nine Magseeds were placed into the breasts of 28 patients under ultrasound guidance. There was no migration of the seeds between placement and surgery. Twenty-seven seeds were placed directly in the target lesion with the other seeds being 2 and 3 mm away. All seeds were detectable transcutaneously in all breast sizes and at all depths. There were no complications or safety issues. CONCLUSIONS: Magnetic seeds are a feasible and safe method of breast lesion localization. They can be accurately placed, demonstrate no migration in this feasibility study and are detectable in all sizes and depths of breast tissue. Now that safety and feasibility have been demonstrated, further clinical studies are required to evaluate the seed's effectiveness in wide local excision surgery. PMID- 29453522 TI - Structural disconnection is responsible for increased functional connectivity in multiple sclerosis. AB - Increased synchrony within neuroanatomical networks is often observed in neurophysiologic studies of human brain disease. Most often, this phenomenon is ascribed to a compensatory process in the face of injury, though evidence supporting such accounts is limited. Given the known dependence of resting-state functional connectivity (rsFC) on underlying structural connectivity (SC), we examine an alternative hypothesis: that topographical changes in SC, specifically particular patterns of disconnection, contribute to increased network rsFC. We obtain measures of rsFC using fMRI and SC using probabilistic tractography in 50 healthy and 28 multiple sclerosis subjects. Using a computational model of neuronal dynamics, we simulate BOLD using healthy subject SC to couple regions. We find that altering the model by introducing structural disconnection patterns observed in those multiple sclerosis subjects with high network rsFC generates simulations with high rsFC as well, suggesting that disconnection itself plays a role in producing high network functional connectivity. We then examine SC data in individuals. In multiple sclerosis subjects with high network rsFC, we find a preferential disconnection between the relevant network and wider system. We examine the significance of such network isolation by introducing random disconnection into the model. As observed empirically, simulated network rsFC increases with removal of connections bridging a community with the remainder of the brain. We thus show that structural disconnection known to occur in multiple sclerosis contributes to network rsFC changes in multiple sclerosis and further that community isolation is responsible for elevated network functional connectivity. PMID- 29453523 TI - Digital versus light microscopy assessment of surgical margin status after radical prostatectomy. AB - Positive surgical margin (PSM) extension reported as focal or non-focal/extensive is an important pathologic prognostic parameter after radical prostatectomy. Likewise, there is limited or no agreement on how to measure and what the best cut-off points to be used in practice are. We hypothesized that digital microscopy (DM) would potentially provide a more objective way to measure PSM and better define its clinical significance. To further our knowledge, we have evaluated PSM status in 107 laparoscopic radical prostatectomies using digital and conventional light microscopy (LM). DM evaluation detected three additional PSM cases, but no differences were seen (LM vs DM; p = 0.220). Mean linear measurement correlated to biochemical recurrence (BR) (LM, p = 0.002; DM, p = 0.001). ROC analysis identified a cut-off point to assess linear measurement by LM (3.5 mm) or DM (3.2 mm), but only digital measurement was significant for BR free survival. Our study also evaluated a cut-off <= 3 mm that was associated to BR using LM (p = 0.023) or DM (p = 0.001). Finally, the number of paraffin blocks bearing PSM correlated with BR (p < 0.001) status with either LM or DM. In conclusion, DM produces similar data than LM but shows more accurate measurements. Reporting of PSM with score of <= 3 vs. > 3 mm linear extent using LM (3.2 mm if digital microscopy is applied) might represent an important prognostic feature after radical prostatectomy. Alternatively, reporting the number of blocks with PSM 1 vs. 2 or more might also provide important prognostic data in practice.

AB - INTRODUCTION: A major clinical challenge in treating allergic contact dermatitis (ACD) is that the first line of treatment is based on the use of corticosteroids. In this study, we aimed to develop a formulation that is devoid of steroids. METHODS: We used mouse ears treated with dinitrofluorobenzene (DNFB) to induce ACD. The efficacy of the test formulation to ameliorate and to prevent induced ACD was determined. RESULTS: To treat this experimentally induced ACD, we developed a formulation containing BIPxine (a mixture of Rosa moschata and Croton lechleri (antioxidants) and Aloe vera and D-panthenol (moisturizers), and hydroglycolic solutions of disodium cromoglycate. Our results show that clear inhibition of ACD took place. The target of this formulation was PAR-2, TRPV4, and other mediators of the inflammatory and pain responses. However, this formulation must be evaluated in other models besides the mouse to confirm its effectiveness. CONCLUSION: The formulation presented here may provide new ACD therapies that do not involve the use of corticosteroids. PMID- 29453526 TI - Characterization of Pm59, a novel powdery mildew resistance gene in Afghanistan wheat landrace PI 181356. AB - KEY MESSAGE: A new powdery mildew resistance gene, designated Pm59, was identified in Afghanistan wheat landrace PI 181356, and mapped in the terminal region of the long arm of chromosome 7A. Powdery mildew, caused by Blumeria graminis f. sp. tritici (Bgt), is an important foliar disease of wheat worldwide. In the Great Plains of the USA, Bgt isolates virulent to widely used powdery mildew resistance genes, such as Pm3a, were previously identified. The objectives of this study were to characterize the powdery mildew resistance gene in Afghanistan landrace PI 181356, which exhibited high resistance to Bgt isolates collected in southern Great Plains, and identify molecular markers for marker assisted selection. An F2 population and F2:3 lines derived from a cross between PI 181356 and OK1059060-126135-3 were used in this study. Genetic analysis indicated that PI 181356 carries a single dominant gene, designated Pm59, in the terminal region of the long arm of chromosome 7A. Pm59 was mapped to an interval between sequence tag site (STS) markers Xmag1759 and Xmag1714 with genetic distances of 0.4 cM distal to Xmag1759 and 5.7 cM proximal to Xmag1714. Physical mapping suggested that Pm59 is in the distal bin 7AL 0.99-1.00. Pm59 is a novel powdery mildew resistance gene, and confers resistance to Bgt isolates collected from the Great Plains and the state of Montana. Therefore, Pm59 can be used to breed powdery mildew-resistant cultivars in these regions. Xmag1759 is ideal for marker-assisted selection of Pm59 in wheat breeding. PMID- 29453528 TI - Longitudinal Analysis of Racial/Ethnic Trends in Quality Outcomes in Community Health Centers, 2009-2014. AB - BACKGROUND: To monitor progress towards eliminating health disparities, community health centers have reported on hypertension control, diabetes control, and birthweight by race and ethnicity since 2008. OBJECTIVE: To evaluate racial/ethnic time trends in quality outcomes in health centers and to assess both within- and between-center disparities in outcomes. DESIGN AND SAMPLE: Using 2009-2014 data from all US health centers (n = 1047 centers, serving 19.6 million patients/year), we evaluated racial/ethnic time trends in quality outcomes for health centers and assessed within- and between-center disparities. MAIN MEASURES: Percentage of patients achieving control of blood pressure < 140/90 mmHg among hypertensive persons, control of glycosylated hemoglobin <= 9.0% among diabetic persons, and birthweight >= 2500 g. All outcomes were reported by race/ethnicity. KEY RESULTS: There was no evidence of improved outcomes among racial/ethnic subgroups from 2009 to 2014, though electronic health record adoption, medical recognition, and insurance coverage rates increased substantially. Two exceptions were increased rates of normal birthweight for black patients (87.0% to 88.8%, or 0.3 percentage points/year, p = 0.02) and decreased rates of diabetes control for white patients (74.2% to 69.5%, or -1.0 percentage points/year, p < 0.01). Within centers, the largest racial/ethnic disparities in 2009 were white/black disparities in hypertension control (8.7 percentage points, 95% CI 7.4-10.1), white/black disparities in diabetes control (3.4 percentage points, 95% CI 2.0-4.7), and white/Hispanic disparities in diabetes control (4.4 percentage points, 95% CI 2.8-6.0). All disparities remained statistically unchanged from 2009 to 2014. White patients were more likely to be seen at a health center in the top performance quintile compared with black and Hispanic patients (p < 0.001). CONCLUSIONS: Though quality outcomes in health centers continued to compare favorably to other care settings, we found no evidence of improved quality or reduced disparities in diabetes control, hypertension control, or birthweight from 2009 to 2014. Within- and between-center racial/ethnic disparities in quality were evident, and both should be targeted in future interventions.

AB - Molecular investigations were performed in order to determine the major characteristics of voltage-gated Na+ channel beta-subunits in mouse vas deferens. The use of real-time quantitative PCR showed that the expression of Scn1b was significantly higher than that of other beta-subunit genes (Scn2b - Scn4b). Immunoreactivity of Scn1b proteins was also detected in the inner circular and outer longitudinal smooth muscle of mouse vas deferens. In whole-cell recordings, the actions of 4,9-anhydroTTX on voltage-gated Na+ current peak amplitude in myocytes (i.e., native INa) were compared with its inhibitory potency on recombinant NaV1.6 channels (expressed in HEK293 cells). A depolarizing rectangular voltage-pulse elicited a fast and transient inward native INa and recombinant NaV1.6 expressed in HEK293 cells (i.e., recombinant INa). The current decay of native INa was similar to the recombinant NaV1.6 current co-expressed with beta1-subunits. The current-voltage (I-V) relationships of native INa were similar to those of recombinant NaV1.6 currents co-expressed with beta1-subunits. Application of 4,9-anhydroTTX inhibited the peak amplitude of native INa (K i = 510 nM), recombinant INa (K i = 112 nM), and recombinant INa co-expressed with beta1-subunits (K i = 92 nM). The half-maximal (Vhalf) activation and inactivation of native INa values were similar to those observed in recombinant INa co-expressed with beta1-subunits. These results suggest that beta1-subunit proteins are likely to be expressed mainly in the smooth muscle layers of murine vas deferens and that 4,9-anhydroTTX inhibited not only native INa but also recombinant INa and recombinant INa co-expressed with beta1-subunits in a concentration-dependent manner. PMID- 29453529 TI - Toxicity Assessment in the Nanoparticle Era. AB - The wide use of engineered nanomaterials in many fields, ranging from biomedical, agriculture, environment, cosmetic, urged the scientific community to understand the processes behind their potential toxicity, in order to develop new strategies for human safety. As a matter of fact, there is a big discrepancy between the increased classes of nanoparticles and the consequent applications versus their toxicity assessment. Nanotoxicology is defined as the science that studies the effects of engineered nanodevices and nanostructures in living organisms. This chapter analyzes the physico-chemical properties of the most used nanoparticles, the way they enter the living organism and their cytoxicity mechanisms at cellular exposure level. Moreover, the current state of nanoparticles risk assessment is reported and analyzed. PMID- 29453530 TI - Mechanisms of Uptake and Translocation of Nanomaterials in the Lung. AB - Nanomaterials are invading our environment due to their increasing use in a very broad range of sectors making human exposure foreseeable during the life cycle of these materials. Inhalation is one of the most frequent routes of exposure in case of unintentional exposure and the small size of nanomaterials allows them to reach the deep lung. Understanding the fate and effects of nanomaterials is a great challenge for scientists as they exhibit a huge physico-chemical diversity that drives their biological reactivity. It is critical to determine the fate of nanomaterials at their route of entry in the organism as this will determine their local and/or systemic effects. In this review we will describe the epithelial barriers and the clearance processes of the respiratory tract. The mechanisms involved in the internalization of nanomaterials by respiratory cells and their ability to cross the epithelial barrier will be presented, highlighting methodologies and the role of the nanomaterial physico-chemical properties. PMID- 29453531 TI - Transmucosal Nanoparticles: Toxicological Overview. AB - Nanoparticles have specific physicochemical properties different to bulk materials of the same composition and such properties make them very attractive for commercial and medical applications. Mucoadhesive nanoparticulate dosage forms are designed to enable prolonged retention of these nanoparticles at the site of application, providing a controlled drug release for improved therapeutic outcome. Moreover, drug delivery across the mucosa bypasses the first-pass hepatic metabolism and avoids the degradation by gastrointestinal enzymes. However, like most new technologies, there is a rising debate concerning the possible transmucosal side effects resulting from the use of particles at the nano level. In fact, these nanoparticles on entering the body, deposit in several organs and may cause adverse biological reactions by modifying the physiochemical properties of living matter. Several investigators have found nanoparticles responsible for toxicity in different organs. In addition, the toxicity of nanoparticles also depends on whether they are persistent or cleared from the different organs of entry and whether the host can raise an effective response to sequester or dispose of the particles. In contrast to many efforts aimed at exploiting desirable properties of nanoparticles for medicine, there are limited attempts to evaluate potentially undesirable effects of these particles when administered intentionally for medical purposes. This chapter focuses on the overview of the mucosal systems, fate of nanoparticles, mechanism of nanoparticle's toxicity and the various toxicity issues associated with nanoparticles through mucosal routes. PMID- 29453532 TI - The Toxicity of Nanoparticles to Human Endothelial Cells. AB - The use of nanoparticles (NPs) in commercially available products and as biomedicinal materials could lead to increasing contact of human blood vessels with NPs, and it is necessary to assess the potential adverse effects of NPs to cells lining blood vessels. Of them, endothelial cells (ECs) are of particular relevance as they play a crucial role in the regulation of function of blood vessels. In this book chapter, I discussed studies that used human ECs to study the toxicity and mechanisms of NPs. It has been shown that exposure of human ECs to NPs could lead to cytotoxicity, genotoxicity, endothelial activation and impaired NO signaling. Oxidative stress and inflammation induced by NPs have been suggested as the mechanisms associated with the toxicity of NPs to ECs, and a three-tier model has been proposed to explain the association between NP induced oxidative stress and toxicity. In recent years, dysfunction of autophagy (excessive autophagy induction) has also been suggested as one of the mechanisms associated with the toxicity of NPs to human ECs. In the future, it is necessary to use human ECs to assess the toxicity of NPs to better understand the potential adverse effects of NPs entering circulation. PMID- 29453533 TI - The Role of Autophagy in Nanoparticles-Induced Toxicity and Its Related Cellular and Molecular Mechanisms. AB - In the past decades, nanoparticles have been widely used in industry and pharmaceutical fields for drug delivery, anti-pathogen, and diagnostic imaging purposes because of their unique physicochemical characteristics such as special ultrastructure, dispersity, and effective cellular uptake properties. But the nanotoxicity has been raised over the extensive applications of nanoparticles. Researchers have elucidated series of mechanisms in nanoparticles-induced toxicity, including apoptosis, necrosis, oxidative stress, and autophagy. Among upon mechanisms, autophagy was recently recognized as an important cell death style in various nanoparticles-induced toxicity, but the role of autophagy and its related cellular and molecular mechanisms during nanoparticles-triggered toxicity were still confusing. In the chapter, we briefly introduced the general process of autophagy, summarized the different roles of autophagy in various nanoparticle-treated different in vitro/in vivo models, and deeply analyzed the physicochemical and biochemical (cellular and molecular) mechanisms of autophagy during nanoparticles-induced toxicity through listing and summarizing representative examples. Physicochemical mechanisms mainly include dispersity, size, charge, and surface chemistry; cellular mechanisms primarily focus on lysosome impairment, mitochondria dysfunction, mitophagy, endoplasmic reticulum stress and endoplasmic reticulum autophagy; while molecular mechanisms were mainly including autophagy related signaling pathways, hypoxia-inducible factor, and oxidative stress. This chapter highlighted the important role of autophagy as a critical mechanism in nanoparticles-induced toxicity, and the physicochemical and biochemical mechanisms of autophagy triggered by nanoparticles might be useful for establishing a guideline for the evaluation of nanotoxicology, designing and developing new biosafety nanoparticles in the future. PMID- 29453534 TI - Nanoparticles-Caused Oxidative Imbalance. AB - Application of nanomaterials in nearly every single branch of industry results in their accumulation in both abiotic environment and tissues of living organisms. Despite the common use of nanomaterials, we are not able to precisely define their toxicity towards humans and surrounding biota. Although we were able to determine final effects of chronic exposure to nanoparticles which consist of many pathologies such as respiratory diseases, allergies, diseases of cardiovascular system, disorders in embryonic life differentiation and growth disorders, toxic effects on the immune system and cancers. The most predominantly investigated feature of most nanoparticles is their ability to induce oxidative stress on cellular level. Imbalance in redox state of cells can lead to various malfunctions in their internal metabolism, which in turn can lead to mentioned pathologies on the organismal level if the exposure is persistent and spread wide enough. Imbalance in redox state translate into production of reactive oxygen species in amounts impossible to be scavenged in given time. Many reactive oxygen species play crucial role in physiological processes in properly functioning cells. It was proven on numerous occasions that abundance of ROS, aside from oxidative damage, can lead to more subtle adverse effects tied to disturbances in intra- and intercellular signaling pathways. In this chapter we would like to address the nanoparticle-induced redox imbalance in cells and its effects. PMID- 29453535 TI - Toxicity of Metal Oxide Nanoparticles. AB - In the recent times, nanomaterials are used in many sectors of science, medicine and industry, without revealing its toxic effects. Thus, it is in urgent need for exploring the toxicity along with the application of such useful nanomaterials. Nanomaterials are categorized with a particle size of 1-100 nm. They have gained increasing attention because of their novel properties, including a large specific surface area and high reaction activity. The various fundamental and practical applications of nanomaterials include drug delivery, cell imaging, and cancer therapy. Nanosized semiconductors have their versatile applications in different areas such as catalysts, sensors, photoelectronic devices, highly functional and effective devices etc. Metal oxides contribute in many areas of chemistry, physics and materials science. Mechanism of toxicity of metal oxide nanoparticles can occur by different methods like oxidative stress, co-ordination effects, non-homeostasis effects, genotoxicity and others. Factors that affect the metal oxide nanoparticles were size, dissolution and exposure routes. This chapter will explain elaborately the toxicity of metal oxide nano structures in living beings and their effect in ecosystem. PMID- 29453536 TI - Relevance of Physicochemical Characterization of Nanomaterials for Understanding Nano-cellular Interactions. AB - The manufactured nanomaterials (NMs) have specific physicochemical properties that confer unique mechanical, optical, electrical and magnetic characteristics that are beneficial for biomedical and industrial applications. However, recent studies have suggested that such specific physicochemical properties of the NMs may define nano-bio interactions thereby determining their toxic potential.One of the major concerns about NMs is the potential to induce cancer, suggested by some experimental studies, as seen for titanium dioxide nanomaterials or carbon nanotubes. To analyze in a short term the carcinogenic properties of a compound, genotoxicity assays in mammalian cell lines or animal models are frequently used. However, the investigation of the genotoxic properties of NMs has been inconclusive, up to date, since divergent results have been reported throughout the literature. While trying to understand how the NMs' characteristics may encompass increased toxicological effects that harbor uncertainties for public health, the use of correlation analysis highlights some physicochemical properties that influence the genotoxic potential of these NM.In this chapter, it is hypothesized that the different genotoxicity observed in closely related NMs may be due to subtle differences in their physicochemical characteristics. The present work provides an overview of the studies exploring the correlation between physicochemical properties of nanomaterials and their genotoxic effects in human cells, with focus on the toxicity of two groups of NMs, titanium dioxide nanomaterials and multiwalled-carbon nanotubes. It is suggested that, for tackling NMs' uncertainties, the in-depth investigation of the nano-bio interactions must be foreseen, where in vitro research must be integrated with in vivo and biomonitoring approaches, to cope with the complex dynamic behaviour of nanoscale materials. PMID- 29453537 TI - Toxicogenomics: A New Paradigm for Nanotoxicity Evaluation. AB - The wider applications of nanoparticles (NPs) has evoked a world-wide concern due to their possible risk of toxicity in humans and other organisms. Aggregation and accumulation of NPs into cell leads to their interaction with biological macromolecules including proteins, nucleic acids and cellular organelles, which eventually induce toxicological effects. Application of toxicogenomics to investigate molecular pathway-based toxicological consequences has opened new vistas in nanotoxicology research. Indeed, genomic approaches appeared as a new paradigm in terms of providing information at molecular levels and have been proven to be as a powerful tool for identification and quantification of global shifts in gene expression. Toxicological responses of NPs have been discussed in this chapter with the aim to provide a clear understanding of the molecular mechanism of NPs induced toxicity both in in vivo and in vitro test models. PMID- 29453538 TI - Nickel Oxide Nanoparticles Induced Transcriptomic Alterations in HEPG2 Cells. AB - Nickel oxide nanoparticles (NiO-NPs) are increasingly used and concerns have been raised on its toxicity. Although a few studies have reported the toxicity of NiO NPs, a comprehensive understanding of NiO-NPs toxicity in human cells is still lagging. In this study, we integrated transcriptomic approach and genotoxic evidence to depict the mechanism of NiO-NPs toxicity in human hepatocellular carcinoma (HepG2) cells. DNA damage analysis was done using comet assay, which showed 26-fold greater tail moment in HepG2 cells at the highest concentration of 100 MUg/ml. Flow cytometric analysis showed concentration dependent enhancement in intracellular reactive oxygen species (ROS). Real-time PCR analysis of apoptotic (p53, bax, bcl2) and oxidative stress (SOD1) genes showed transcriptional upregulation. Transcriptome analysis using qPCR array showed over expression of mRNA transcripts related to six different cellular pathways. Our data unequivocally suggests that NiO-NPs induces oxidative stress, DNA damage, apoptosis and transcriptome alterations in HepG2 cells. PMID- 29453539 TI - Nanoparticle-Protein Interaction: The Significance and Role of Protein Corona. AB - The physico-chemical properties of nanoparticles, as characterized under idealized laboratory conditions, have been suggested to differ significantly when studied under complex physiological environments. A major reason for this variation has been the adsorption of biomolecules (mainly proteins) on the nanoparticle surface, constituting the so-called "biomolecular corona". The formation of biomolecular corona on the nanoparticle surface has been reported to influence various nanoparticle properties viz. cellular targeting, cellular interaction, in vivo clearance, toxicity, etc. Understanding the interaction of nanoparticles with proteins upon administration in vivo thus becomes important for the development of effective nanotechnology-based platforms for biomedical applications. In this chapter, we describe the formation of protein corona on nanoparticles and the differences arising in its composition due to variations in nanoparticle properties. Also discussed is the influence of protein corona on various nanoparticle activities. PMID- 29453540 TI - Cellular and Molecular Toxicity of Iron Oxide Nanoparticles. AB - Iron oxide nanoparticles (ION) have attracted much attention because of their particular physico-chemical properties, including superparamagnetism. These features make them suitable for many purposes and several interesting biomedical applications, such as to increase contrast in magnetic resonance imaging (MRI), as drug delivery systems and as hyperthermia agents. However, they have also shown to be easily accumulated in diverse tissues and induce toxicity at different levels. This chapter reviews the different cellular and molecular effects induced by ION reported from in vitro studies with human and non-human cell lines. Those effects are mainly dependent on ION type and concentration, time of exposure, presence and nature of coating, and cell type evaluated. They include decreases in viability, plasmatic membrane disruption, oxidative damage, mitochondrial alterations, cell cycle impairments, cytoskeleton disruption, cell death, and alterations in cell motility, and in cell integrity. Despite these negative effects, the numerous advantages of ION together with their promising applications in biomedicine, make it necessary to clearly define their toxicity in order to discard potential health risks and to reach optimal benefits of their use. PMID- 29453541 TI - Detection of DNA Damage Induced by Cerium Dioxide Nanoparticles: From Models to Molecular Mechanism Activated. AB - This chapter will present an original effort to summarize the relevant data about the cyto-genotoxicity induced by cerium dioxide nanoparticles (nanoceria) in physiologically (in vivo and in vitro) relevant models. In this way, this chapter should be extremely useful to everyone who wants to plan their research and publishing their results. Massive application of nanoceria at different fields is increasing year after year, and it is urgent to address and discuss their use and its safety-related issues. Specifically, the nanoceria are being designed for nanomedicine, cosmetics, polishing materials and additives for automotive fuels. Their unique properties include the ability to absorb UV radiation, antioxidant potential and the rapid exchange of valence between Ce4+ and Ce3+ ions associated to oxygen storage. In this chapter, the state of the art regarding the physicochemical properties of nanoceria, nanogenotoxicity detected by in vitro and in vivo systems and the general aspects in the cyto-genotoxic mechanism of nanoceria are summarized. The cyto-genotoxicity will be discussed in terms of evaluations by Comet assay, Micronucleus test, DNA damage response and oxidative stress detected in cell culture systems and in vivo test. We also described the dose dependent cyto-genotoxic effects of nanoceria based on their physical chemical nature. Paradoxically, these particles have been characterized as either pro-oxidant or anti-oxidant in dependence of microenvironment and physiological conditions such as pH. Finally, this chapter will contribute to point out aspects of the development of new in vitro and in vivo methodologies to detect cyto genotoxic effects of the nanoceria. PMID- 29453542 TI - Mechanisms Underlying Neurotoxicity of Silver Nanoparticles. AB - The potent antimicrobial properties of nanoparticulate silver (AgNPs) have led to broad interest in using them in a wide range of commercial and medical applications. Although numerous in vivo and in vitro studies have provided evidence of toxic effects, rapid commercialization of AgNP-based nanomaterials has advanced without characterization of their potential environmental and health hazards. There is evidence that AgNPs can be translocated from the blood to the brain, regardless the route of exposure, and accumulate in the brain over time. As the brain is responsible for basic physiological functions and controls all human activities, it is important to assess the hazardous influence of AgNPs released from widely used nanoproducts and possible side effects of AgNP-based therapies. A number of studies have suggested that the size, shape and surface coating, as well as rates of silver ion release and interactions with proteins are the key factors determining the neurotoxicity of AgNPs. AgNPs target endothelial cells forming the blood-brain barrier, neurons and glial cells and leads finally to oxidative stress-related cell death. In this chapter, we review in detail current data on the impact of AgNPs on the central nervous system and discuss the possible mechanisms of their neurotoxic effects. PMID- 29453543 TI - Toxic and Beneficial Potential of Silver Nanoparticles: The Two Sides of the Same Coin. AB - Nanotechnology has allowed great changes in chemical, biological and physical properties of metals when compared to their bulk counterparts. Within this context, silver nanoparticles (AgNPs) play a major role due to their unique properties, being widely used in daily products such as fabrics, washing machines, water filters, food and medicine. However, AgNPs can enter cells inducing a "Trojan-horse" type mechanism which potentially leads to cellular autophagy, apoptosis or necrosis. On the other hand, this cytotoxicity mechanism can be optimized to develop drug nanocarriers and anticancer therapies. The increasing use of these NPs entails their release into the environment, damaging ecosystems balance and representing a threat to human health. In this context, the possible deleterious effects that these NPs may represent for the biotic and abiotic ecosystems components represent an obstacle that must be overcome in order to guarantee the safety use of their unique properties. PMID- 29453544 TI - Molecular and Cellular Toxicology of Nanomaterials with Related to Aquatic Organisms. AB - The increasing application of nanomaterials both in commercial and industrial products has led their accumulation in the aquatic ecosystem. The rapid development and large scale production of nanomaterials in the last few decades have stimulated concerns regarding their potential environmental health risks on aquatic biota. Inorganic nanoparticles, due to their unique properties and associated material characteristics resulted in toxicity of these nanomaterials in aquatic organisms. Understanding their novel properties at nanoscale has established to be a significant aspect of their toxicity. Unique properties such as size, surface area, surface coating, surface charge, aggregation of particles and dissolution may affect cellular uptake, molecular response, in vivo reactivity and delivery across tissues of living organism. Already lot of research in the past three or four decades within the nano-ecotoxicology field had been carried out. However, there is not any standard technique yet to assess toxicity of nanoparticles (NPs) on different biological systems such as reproductive, respiratory, nervous, gastrointestinal systems, and development stages of aquatic organisms. Specific toxicological techniques and quantification of nanoparticles are vital to establish regulations to control their impact on the aquatic organism and their release in the aquatic environment. The main aim of this chapter is to critically evaluate the current literature on the toxicity of nanomaterials on aquatic organism. PMID- 29453545 TI - Cytotoxicity and Physiological Effects of Silver Nanoparticles on Marine Invertebrates. AB - Silver nanoparticles (AgNPs) incorporation in commercial products is increasing due to their remarkable physical and chemical properties and their low cost on the market. Silver has been known for a long time to be highly toxic to bacterial communities, aquatic organisms, and particularly to marine biota. Strong chloro complexes dominate Ag speciation in seawater and facilitate its persistence in dissolved form. It has a great impact on marine organisms because low concentration of silver can lead to strong bioaccumulation, partly because the neutral silver chloro complex (AgCl0) is highly bioavailable. Owing to the fact that estuaries and coastal areas are considered as the ultimate fate for AgNPs, the study of their toxic effects on marine invertebrates can reveal some environmental risks related to nanosilver exposure. In an attempt to reach this goal, many invertebrate taxa including mollusks, crustaceans, echinoderms and polychaetes have been used as biological models. The main findings related to AgNP toxicity and marine invertebrates are summarized hereafter. Some cellular mechanisms involving nano-internalization (cellular uptake, distribution and elimination), DNA damaging, antioxidant cellular defenses and protein expression are discussed. Physiological effects on early stage development, silver metabolic speciation, immune response, tissue damaging, anti-oxidant effects and nano depuration are also described. Finally, we paid attention to some recent interesting findings using sea urchin developmental stages and their cells as models for nanotoxicity investigation. Cellular and physiological processes characterizing sea urchin development revealed new and multiple toxicity mechanisms of both soluble and nano forms of silver. PMID- 29453546 TI - A Drosophila Model to Decipher the Toxicity of Nanoparticles Taken Through Oral Routes. AB - In recent era, nanoparticles (NPs) are widely used in food, medicine and body implants. Besides it's wide use being a foreign particle it may have some noxious effect on the body. To understand the mechanistic role of NPs toxicity, Drosophila appeared to be a superior model organism. Toxicity of several nanoparticles were accessed using Drosophila. The NPs, after oral route of exposure enter into the gut, crosses the barrier of peritrophic membrane and induces apoptosis. The toxicity of NPs within gut resulted in developmental delay, with decrease in pupa count, fly hatching along with weight loss. The adult fly hatched after nanoparticle treatment shows increasing phenotypic defect in various sensory organs as well as in different body parts. Besides phenotypic defect some of the nanoparticle results altered behavioural phenotypes like larva crawling or adult climbing. Alteration of both phenotypic as well as behavioural assay clearly hints that signalling pathway like Notch, Wnt, EGFR etc. get affected due to exposure of nanoparticle. Results from various labs prove that nanoparticle can mediate developmental defect by altering signalling pathways. Since many of the signalling pathways are conserved the effect seen in model organisms cannot be overlooked. All the nanoparticles used in food and medicine should be modified to nullify the toxic effect before used in food and medicine. PMID- 29453547 TI - Using of Quantum Dots in Biology and Medicine. AB - Quantum dots are nanoparticles, which due to their unique physical and chemical (first of all optical) properties, are promising in biology and medicine. There are many ways for quantum dots synthesis, both in the form of nanoislands self forming on the surfaces, which can be used as single-photon emitters in electronics for storing information, and in the form of colloidal quantum dots for diagnostic and therapeutic purposes in living systems. The paper describes the main methods of quantum dots synthesis and summarizes medical and biological ways of their use. The main emphasis is laid on the ways of quantum dots surface modification. Influence of the size and form of nanoparticles, charge on the surfaces of quantum dots, and cover type on the efficiency of internalization by cells and cell compartments is shown. The main mechanisms of penetration are considered. PMID- 29453548 TI - [Big data from clinical routine]. AB - BACKGROUND: Over the past 100 years, evidence-based medicine has undergone several fundamental changes. Through the field of physiology, medical doctors were introduced to the natural sciences. Since the late 1940s, randomized and epidemiological studies have come to provide the evidence for medical practice, which led to the emergence of clinical epidemiology as a new field in the medical sciences. Within the past few years, big data has become the driving force behind the vision for having a comprehensive set of health-related data which tracks individual healthcare histories and consequently that of large populations. OBJECTIVES: The aim of this article is to discuss the implications of data-driven medicine, and to examine how it can find a place within clinical care. MATERIALS AND METHODS: The EU-wide discussion on the development of data-driven medicine is presented. RESULTS: The following features and suggested actions were identified: harmonizing data formats, data processing and analysis, data exchange, related legal frameworks and ethical challenges. For the effective development of data driven medicine, pilot projects need to be conducted to allow for open and transparent discussion on the advantages and challenges. The Federal Ministry of Education and Research ("Bundesministerium fur Bildung und Forschung," BMBF) Arthromark project is an important example. Another example is the Medical Informatics Initiative of the BMBF. DISCUSSION AND CONCLUSION: The digital revolution affects clinic practice. Data can be generated and stored in quantities that are almost unimaginable. It is possible to take advantage of this for development of a learning healthcare system if the principles of medical evidence generation are integrated into innovative IT-infrastructures and processes. PMID- 29453549 TI - The German REACH Congress 2016: a workshop report. AB - In October 2016, the German REACH Congress was held at the German Federal Institute for Risk Assessment (BfR) in Berlin. Here, the associated improvement made in the fields of consumer protection and the progress in and experiences gained from the implementation of the authorisation procedure were discussed. Several speakers from EU institutions, German authorities, industry, and civil society organisations were invited to present their views. There was a shared consensus that REACH contributes to the advancement of consumer protection against chemical risks, mainly because more and higher quality information on substance-related hazards and potential exposures becomes available. In addition, risk management measures, particularly regarding restrictions on uses, scale down consumer exposures to chemicals. Opportunities for improvements identified at the congress include the quality of registration dossiers and the management of and communication on substances of very high concern (SVHC) that may be present in consumer articles. Although regarded as being in an early implementation phase, the authorisation process was generally found to be operational and progressing well. Criticism was expressed with regard to the consistency of authorisation decisions and the costs and uncertainties related to authorisation applications. Consumer protection legislation consists of several legal provisions which are interlinked. The congress participants agreed that REACH is an important element of this legal framework as it enhances and complements other legal provisions.

AB - We examined associations with HIV recent infection and estimated transmitted drug resistance (TDR) prevalence among 3345 men at sexually transmitted infection clinics in Mumbai (2002-2005). HIV seroincidence was 7.92% by the BED-CEIA and was higher at a clinic located near brothels (12.39%) than at a hospital-based clinic (3.94%). HIV recent infection was associated with a lifetime history of female sex worker (FSW) partners, HSV-2, genital warts, and gonorrhea. TDR prevalence among recent infection cases was 5.7%. HIV testing services near sex venues may enhance case detection among high-risk men who represent a bridging population between FSWs and the men's other sexual partners. PMID- 29453552 TI - HIV-Related Stigma, Social Support, and Psychological Distress Among Individuals Initiating ART in Ethiopia. AB - Recent World Health Organization HIV treatment guideline expansion may facilitate timely antiretroviral therapy (ART) initiation. However, large-scale success of universal treatment strategies requires a more comprehensive understanding of known barriers to early ART initiation. This work aims to advance a more comprehensive understanding of interrelationships among three known barriers to ART initiation: psychological distress, HIV-related stigma, and low social support. We analyzed cross-sectional interview data on 1175 adults initiating ART at six HIV treatment clinics in Ethiopia. Experience of each form of HIV-related stigma assessed (e.g., anticipatory, internalized, and enacted) was associated with increased odds of psychological distress. However, among those who reported enacted HIV-related stigma, there was no significant association between social support and psychological distress. Interventions to improve mental health among people living with HIV should consider incorporating components to address stigma, focusing on strategies to prevent or reduce the internalization of stigma, given the magnitude of the relationship between high internalized stigma and psychological distress. Interventions to increase social support may be insufficient to improve the mental health of people living with HIV who experienced enacted HIV-related stigma. Future research should examine alternative strategies to manage the mental health consequences of enacted HIV related stigma, including coping skills training.

AB - Atopic dermatitis affects roughly 20% of children and 3% of adults in Germany and other industrial countries, with an increasing prevalence. Its causality has still not been conclusively clarified but a type-2 T-helper cell mediated immunity reaction (type 2 immunity) dominates cutaneous inflammation. In the quest for the underlying pathogenic mechanisms and the development of improved prevention and treatment options, attention is also increasingly being paid to the influence of microbial colonization. This is facilitated by the rapid development of microbial analysis by sequencing. An increasing number of studies have shown that there is a link between disorders of the skin microbiome and the occurrence of atopic eczema and some also point towards the intestinal microbiome. In particular, a loss of diversity regarding the composition of the microbiome has been observed. PMID- 29453554 TI - In vitro studies of DNA damage and repair mechanisms induced by BNCT in a poorly differentiated thyroid carcinoma cell line. AB - Boron neutron capture therapy (BNCT) for aggressive tumors is based on nuclear reaction [10B (n, alpha) 7Li]. Previously, we demonstrated that BNCT could be applied for the treatment of undifferentiated thyroid carcinoma. The aim of the present study was to describe the DNA damage pattern and the repair pathways that are activated by BNCT in thyroid cells. We analyzed gammaH2AX foci and the expression of Ku70, Rad51 and Rad54, main effector enzymes of non-homologous end joining (NHEJ) and homologous recombination repair (HRR) pathways, respectively, in thyroid follicular carcinoma cells. The studied groups were: (1) C [no irradiation], (2) gamma [60Co source], (3) N [neutron beam alone], (4) BNCT [neutron beam plus 10 ug 10B/ml of boronphenylalanine (10BPA)]. The total absorbed dose was always 3 Gy. The results showed that the number of nuclear gammaH2AX foci was higher in the gamma group than in the N and BNCT groups (30 min-24 h) (p < 0.001). However, the focus size was significantly larger in BNCT compared to other groups (p < 0.01). The analysis of repair enzymes showed a significant increase in Rad51 and Rad54 mRNA at 4 and 6 h, respectively; in both N and BNCT groups and the expression of Ku70 did not show significant differences between groups. These findings are consistent with an activation of HRR mechanism in thyroid cells. A melanoma cell line showed different DNA damage pattern and activation of both repair pathways. These results will allow us to evaluate different blocking points, to potentiate the damage induced by BNCT.

AB - The aim of this study was to investigate the effect of hyperthermia, 6 MeV electron radiation and combination of these treatments on cancer cell line DU145 in both monolayer culture and spheroids enriched for prostate cancer stem cells (CSCs). Flowcytometric analysis of the expression of molecular markers CD133+/CD44+ was carried out to determine the prostate CSCs in cell line DU145 grown as spheroids in serum-free medium. Following monolayer and spheroid culture, DU145 cells were treated with different doses of hyperthermia, electron beam and combination of them. The survival and self-renewing of the cells were evaluated by colony formation assay (CFA) and spheroid formation assay (SFA). Flowcytometry results indicated that the percentage of CD133+/CD44+ cells in spheroid culture was 13.9-fold higher than in the monolayer culture. The SFA showed significant difference between monolayer and spheroid culture for radiation treatment (6 Gy) and hyperthermia (60 and 90 min). The CFA showed significantly enhanced radiosensitivity in DU145 cells grown as monolayer as compared to spheroids, but no effect of hyperthermia. In contrast, for the combination of radiation and hyperthermia the results of CFA and SFA showed a reduced survival fraction in both cultures, with larger effects in monolayer than in spheroid culture. Thus, hyperthermia may be a promising approach in prostate cancer treatment that enhances the cytotoxic effect of electron radiation. Furthermore, determination and characterization of radioresistance and thermoresistance of CSCs in the prostate tumor is the key to develop more efficient therapeutic strategies.

AB - Nitrogen efficiency of lactating buffalo can be increased by providing dietary crude protein (CP) precisely to the requirement. Twelve lactating Nili-Ravi buffaloes (6 primiparous and 6 multiparous) at 76 +/- 37.5 days in milk (DIM) were used in this study. The treatments were diets providing three levels of CP (% DM basis): (1) low-protein = 11%; (2) medium-protein = 13.1%; (3) high-protein = 14.2% according to a 3 * 3 Latin square design. The period length of each treatment was 21 days and the total duration of experiment was 63 days. The diets were designed to provide similar energy. The nitrogen intake of buffalo increased linearly by increasing CP levels. Dry matter intake showed a tendency toward decrease in quadratic fashion, whereas milk yield decreased linearly in high protein diet. No effect was observed on milk protein yield and content. Increasing the dietary CP levels increased plasma urea nitrogen, whereas glucose and triacylglycerol levels remain unaffected. Efficiency of dietary nitrogen utilization to milk averaged 21% and showed both linear and quadratic decreases by increasing the protein supply levels. In conclusion, low CP level showed higher milk production with low plasma urea nitrogen and high nitrogen efficiency in this experiment.

AB - OBJECTIVES: Regional primary health-care organisations plan, co-ordinate, and fund some primary health-care services in a designated region. This article presents a framework for examining the equity performance of regional primary health-care organisations, and applies it to Australian Medicare Locals (funded from 2011 to 2015). METHODS: The framework was developed based on theory, literature, and researcher deliberation. Data were drawn from Medicare Local documents, an online survey of 210 senior Medicare Local staff, and interviews with 50 survey respondents. RESULTS: The framework encompassed equity in planning, collection of equity data, community engagement, and strategies to address equity in access, health outcomes, and social determinants of health. When the framework was applied to Medicare Locals, their inclusion of equity as a goal, collection of equity data, community engagement, and actions improving equity of access were strong, but there were gaps in broader advocacy, and strategies to address social determinants of health, and equity in quality of care. CONCLUSIONS: The equity framework allows a platform for advancing knowledge and international comparison of the health equity efforts of regional primary health-care organisations. PMID- 29453560 TI - Establishment of Primary Culture of Sertoli Cells. AB - The successful isolation and culture of Sertoli cells depend on a series of delicate processes of mechanical isolation and enzymatic digestion of the testicular tissue, taking advantage of an array of enzymes (such as DNAse, collagenase, and pancreatin) in order to digest the extracellular matrix components. The complexity of these processes may present some differences depending on the origin of the testicular sample (whole tissue or biopsy) and of the species in question. Rat and mouse Sertoli cells are obtained by a similar protocol, whereas bovine and human Sertoli cells require a more extensive mechanical and enzymatic processing. PMID- 29453559 TI - Regulation of H+-pyrophosphatase by 14-3-3 Proteins from Arabidopsis thaliana. AB - Plant vacuolar H+-transporting inorganic pyrophosphatase (V-PPase; EC 3.6.1.1) is a crucial enzyme that exists on the tonoplast to maintain pH homeostasis across the vacuolar membrane. This enzyme generates proton gradient between cytosol and vacuolar lumen by hydrolysis of a metabolic byproduct, pyrophosphate (PP i ). The regulation of V-PPase at protein level has drawn attentions of many workers for decades, but its mechanism is still unclear. In this work, we show that AVP1, the V-PPase from Arabidopsis thaliana, is a target protein for regulatory 14-3-3 proteins at the vacuolar membrane, and all twelve 14-3-3 isoforms were analyzed for their association with AVP1. In the presence of 14-3-3nu, -u, -omicron, and iota, both enzymatic activities and its associated proton pumping of AVP1 were increased. Among these 14-3-3 proteins, 14-3-3 u shows the highest stimulation on coupling efficiency. Furthermore, 14-3-3nu, -u, -omicron, and -iota exerted protection of AVP1 against the inhibition of suicidal substrate PP i at high concentration. Moreover, the thermal profile revealed the presence of 14-3 3omicron improves the structural stability of AVP1 against high temperature deterioration. Additionally, the 14-3-3 proteins mitigate the inhibition of Na+ to AVP1. Besides, the binding sites/motifs of AVP1 were identified for each 14-3 3 protein. Taken together, a working model was proposed to elucidate the association of 14-3-3 proteins with AVP1 for stimulation of its enzymatic activity. PMID- 29453558 TI - Inorganic nanoparticles in diagnosis and treatment of breast cancer. AB - Nanoparticles are being actively developed for biomolecular profiling of cancer biomarkers, tumor imaging in vivo, and targeted drug delivery. These nanotechnology-based techniques can be applied widely in the management of different malignant diseases, such as breast cancer. Although the number of different types of nanoparticles is increasing rapidly, most can be classified into two major types: particles that contain organic molecules as a major building material (such as dendrimers, micelles, liposomes and carbon nanotubes, and other polymers); and those that use inorganic elements, usually metals, as a core. In particular, inorganic nanoparticles have received increased attention in the recent past as potential diagnostic and therapeutic systems in the field of oncology. This review primarily discusses progress in applications of inorganic nanoparticles for breast cancer imaging and treatment. PMID- 29453561 TI - Evaluation of the Purity of Sertoli Cell Primary Cultures. AB - The purity of the primary cultures of Sertoli cells is a factor for the validation of the studies using this methodological approach. There is a probability of contamination of these cultures with other testicular cellular types, such as peritubular cells and germ cells (that represent a large percentage of the volume of the seminiferous tubules).For the evaluation of the purity of cultures, the immunocytochemistry technique (immunoperoxidase or immunofluorescence) is frequently used to label a protein marker specific for the Sertoli cells within the testicular environment. The expression of several protein markers can be used, with different particularities, being that vimentin is often used as a marker for Sertoli cells. Vimentin is expressed independently of the differentiation state of the cells and is observed around the nuclei and in the cytoplasm of Sertoli cells. PMID- 29453562 TI - Preparation of Testicular Samples for Histology and Immunohistochemistry. AB - One approach to visualize internal structures of the testis is histological sectioning of the material. The use of testicular samples allows a detailed analysis of the structure of both seminiferous tubules and the interstitial space. It is worth noting that key role in the control of germ cell development is assigned to Sertoli cells. Thus, in this chapter the special reference is made on visualization of Sertoli cells in the seminiferous epithelium in which they create a specialized microenvironment to support the germ cell development through the formation of the blood-testis barrier (BTB). The use of transmission electron microscopy (TEM) allows a deeper insight into the BTB morphology, especially the organization of the basal ectoplasmic specialization (ES) and coexisting intercellular junctions.Equally important, immunohistochemistry (IHC) is an appropriate technique to detect the localization of various proteins in paraffin-embedded and fixed tissues, i.e. testicular samples. A proper fixation allows to stabilize structure of the seminiferous tubules and preserve cells against irreversible damage. As such localization of various junction proteins connecting adjoined Sertoli cells and present in germ cell-Sertoli cell interfaces is possible. Also immunofluorescence (IF) is helpful to detect the distribution and relative abundance of the junctional proteins, while immunocytochemistry (ICC) is a valuable technique to show a protein distribution within a single cell (e.g. in Sertoli cell culture). PMID- 29453563 TI - Rabbit Sertoli Cells: Immunohistochemical Profile from Neonatal to Adult Age. AB - Immunohistochemistry (IHC) on formalin-fixed paraffin-embedded tissue specimens is a widely used laboratory technique that allows the demonstration and the direct microscopical observation of antigens within tissue sections by means of specific antibodies. IHC is one the best tools to define the immunophenotype of a cell during maturation or neoplastic transformation.To investigate the immunophenotype of postnatal rabbit Sertoli cell, from neonatal to adult age, in this chapter, the immunohistochemical protocol described is one of the most common: the avidin-biotin complex (ABC) method. PMID- 29453564 TI - Identification of Proliferative and Apoptotic Sertoli Cells Using Fluorescence and Confocal Microscopy. AB - Sertoli cells, the testicular somatic cells of the seminiferous epithelium, are vital for the survival of the epithelium. They undergo proliferation and apoptosis during fetal, neonatal, and prepubertal development. Apoptosis is increased in certain situations such as exposure to many substances, for example, toxics, or short photoperiod in the non-breeding season of some mammals. Therefore, it has always been considered that Sertoli cells that reach adulthood are quiescent cells, that is to say, nonproliferative, do not die, are terminally differentiated, and whose numbers remain constant. Recently, a degree of both proliferation and apoptosis has been observed in normal adult conditions, suggesting that consideration of this cell as quiescent may be subject to change. All this make it necessary to use histochemical techniques to demonstrate whether Sertoli cells are undergoing proliferation or apoptosis in histological sections and to allow the qualitative and quantitative study of these. In this chapter, we present two double-staining techniques that can be used for identifying Sertoli cells in proliferation or apoptosis by fluorescence microscopy. In both, the Sertoli cells are identified by an immunohistochemistry for vimentin followed by an immunohistochemistry for PCNA or a TUNEL histochemistry. PMID- 29453565 TI - Sertoli Cell Preparation for Co-immunoprecipitation. AB - Most techniques to study protein-protein interactions, gene expression or signal transduction, among others, in Sertoli cells, depend on obtaining a protein extract of such cells. This is accomplished by lysing the Sertoli cells and solubilizing the intracellular proteins. Depending on the purpose of your study, the technique used to lyse and consequently obtain protein extracts from Sertoli cells must be considered. In this chapter, we will focus on how to obtain a protein Sertoli cell extract suitable for co-immunoprecipitation technique. PMID- 29453566 TI - Profiling Signaling Proteins in Sertoli Cells by Co-immunoprecipitation. AB - Sertoli cells are crucial for germ cell support, create a suitable environment for spermatogenesis, and integrate information from the nervous system and germ cell line. To fully understand the role of Sertoli cells, it is necessary to characterize the protein-protein interactions. Identifying the interactome of a given protein may provide leads about the role and molecular mechanism of such protein in Sertoli cells. One of the techniques to characterize protein interactomes consists of co-immunoprecipitation followed by mass spectrometry or Western blot. Co-immunoprecipitation enables the isolation of a protein target and interactome under physiological conditions. In this chapter, we described how to perform an interactomic study using the co-immunoprecipitation technique in Sertoli cells. Moreover, we will focus on how to analyze and interpret the results of a co-immunoprecipitation before mass spectrometry analysis. PMID- 29453567 TI - Phagocytosis by Sertoli Cells: Analysis of Main Phagocytosis Steps by Confocal and Electron Microscopy. AB - Sertoli cells were discovered in the seminiferous tubules by Enrico Sertoli in 1865 (Morgagni 7:31-33, 1865). Intense phagocytosis is, in the context of spermatogenesis cycle, morphologically the most noticeable function of Sertoli cells. In this chapter the major principles of phagocytosis machinery and its specificities in the seminiferous tubules will be briefly reviewed, guidelines of analysis of main phagocytosis steps by confocal and transmission electron microscopy will be described, and a simplified method to assess phagocytosis rate in routine experiments will be given. PMID- 29453569 TI - Assessing Autophagy in Sertoli Cells. AB - Autophagy is an important cellular homeostatic process, it degrades most long lived proteins and some organelles by lysosome to provide raw materials for the survival of the cells during nutrient or energy deprivation condition. Autophagy is active in Sertoli cells and involved in many cellular processes. However, the precise role of autophagy in Sertoli cells is still largely unknown. Thus, the assessment of autophagy in Sertoli cells should be helpful for investigating the functional roles of autophagy in Sertoli cells. This chapter describes some methods for assessing autophagy in Sertoli cells, including detection of LC3 maturation/aggregation, transmission electron microscopy, half-life assessments of long-lived proteins, immunofluorescence microscopy, and co-localization of autophagy-targeted proteins with autophagy components or lysosomal proteins. PMID- 29453568 TI - A Method for In Vivo Induction and Ultrastructural Detection of Mitophagy in Sertoli Cells. AB - An emerging body of evidences based on in vitro studies indicate that mitophagy (selective autophagic clearance of damaged mitochondria) is a prosurvival mechanism, specifically under exposure to various stressors. Sertoli cells (SCs) play essential roles in maintenance of spermatogenesis via paracrine interactions with germ cells and other somatic cells in the testis; however, studies investigating mitophagy in SCs are still very few. In this chapter, we give a brief review of mechanisms and detection methods of mitophagy in SCs based on our recent publications on animal models of ethanol toxicity and current literature. In addition, we provide a method for induction and ultrastructural identification of mitophagy in SCs of adult Wistar rats using a single intraperitoneal injection (5 g/kg) of ethanol. Proper understanding of mitophagy features and mechanisms in SCs may have therapeutic implications for infertility associated with alcoholism and other diseases characterized by mitochondrial dysfunction. PMID- 29453570 TI - Molecular Mechanisms and Signaling Pathways Involved in the Nutritional Support of Spermatogenesis by Sertoli Cells. AB - Sertoli cells play a central role in spermatogenesis. They maintain the blood testis barrier, an essential feature of seminiferous tubules which creates the proper environment for the occurrence of the spermatogenesis. However, this confinement renders germ cells almost exclusively dependent on Sertoli cells' nursing function and support. Throughout spermatogenesis, differentiating sperm cells become more specialized, and their biochemical machinery is insufficient to meet their metabolic demands. Although the needs are not the same at all differentiation stages, Sertoli cells are able to satisfy their needs. In order to maintain the seminiferous tubule energetic homeostasis, Sertoli cells react in response to several metabolic stimuli, through signaling cascades. The AMP activated kinase, sensitive to the global energetic status; the hypoxia-inducible factors, sensitive to oxygen concentration; and the peroxisome proliferator activated receptors, sensitive to fatty acid availability, are pathways already described in Sertoli cells. These cells' metabolism also reflects the whole-body metabolic dynamics. Metabolic diseases, including obesity and type II diabetes mellitus, induce changes that, both directly and indirectly, affect Sertoli cell function and, ultimately, (dys)function in male reproductive health. Insulin resistance, increased estrogen synthesis, vascular disease, and pubic fat accumulation are examples of metabolic-related conditions that affect male fertility potential. On the other hand, malnutrition can also induce negative effects on male sexual function. In this chapter, we review the molecular mechanisms associated with the nutritional state and male sexual (dys)function and the central role played by the Sertoli cells. PMID- 29453571 TI - Assessing Sertoli Cell Metabolic Activity. AB - Nuclear magnetic resonance (NMR)-based metabolomics is widely used in the research of metabolic conditions of complex biological systems under various conditions, and its use has been found in the field of male fertility. Here we describe the implementation of total and targeted NMR-based metabolomics in the research on Sertoli cell metabolism. Main principles and techniques of cell medium, cellular extracts, and intact cells are explained, as well as some classical experiments that can give complementary information on the Sertoli cell metabolism. PMID- 29453572 TI - Proteome Profiling of Sertoli Cells Using a GeLC-MS/MS Strategy. AB - Proteomics is a technology that allows to decipher the molecular networks involved in the regulation of biological processes such as spermatogenesis. Sertoli cells (SCs) are key players in the paracrine control of this process. Envisioning to increase the knowledge on the molecular networks harbored in SCs, we propose a methodology based on GeLC-MS/MS for the characterization of these cells' proteome. Proteins are separated by SDS-PAGE hyphenated to HPLC and identified by mass spectrometry. The integration of data with bioinformatics tools such as ClueGO + CluePedia from Cytoscape allows the identification of the biological pathways more prevalent in SCs, and that might be modulated by pathophysiological conditions. Moreover, the proteome analysis with tools as SignalP/SecretomeP highlights the proteins more prone to be secreted and involved in the paracrine control of germ cells, which might also be deregulated by diseases. PMID- 29453573 TI - Gene Silencing of Human Sertoli Cells Utilizing Small Interfering RNAs. AB - Sertoli cells, as the unique somatic cells within the seminiferous tubules, play essential roles in regulating normal spermatogenesis. In addition, recent studies have demonstrated that Sertoli cells could have significant applications in regenerative medicine due to their great plasticity. However, the roles of genes in controlling the fate determinations of human Sertoli cells remain largely unknown. Silencing genes of human Sertoli cells utilizing small interfering RNAs (siRNAs) is an important method to explore their functions and mechanisms in human Sertoli cells. We isolated and identified human Sertoli cells. RNA interference (RNAi) was employed to probe the roles and signaling pathways of BMP6 and BMP4 in mediating the proliferation and apoptosis of human Sertoli cells. Specifically, siRNAs against BMP6 and BMP4 were used to knock down the expression levels of BMP6 and BMP4 and examine the function and mechanism in controlling the fate decisions of human Sertoli cells. In this chapter, we provided the detailed methods of RNAi in silencing BMP6 gene of human Sertoli cells. Quantitative real-time PCR demonstrated that the designed BMP6 siRNAs apparently silenced BMP6 mRNA in human Sertoli cells at 24 h after transfection. Western blots showed that the siRNAs silenced the expression of BMP6 protein effectively at 48 h after transfection. In summary, siRNAs can effectively and specifically knock down targeting genes at both transcriptional and translational levels utilizing RNAi in human Sertoli cells. PMID- 29453574 TI - Testicular Cell Selective Ablation Using Diphtheria Toxin Receptor Transgenic Mice. AB - Testis development and function is regulated by intricate cell-cell cross talk. Characterization of the mechanisms underpinning this has been derived through a wide variety of approaches including pharmacological manipulation, transgenics, and cell-specific ablation of populations. The removal of all or a proportion of a specific cell type has been achieved through a variety of approaches. In this paper, we detail a combined transgenic and pharmacological approach to ablate the Sertoli or germ cell populations using diphtheria toxin in mice. We describe the key steps in generation, validation, and use of the models and also describe the caveats and cautions necessary. We also provide a detailed description of the methodology applied to characterize testis development and function in models of postnatal Sertoli or germ cell ablation. PMID- 29453575 TI - Regulation of Blood-Testis Barrier (BTB) Dynamics, Role of Actin-, and Microtubule-Based Cytoskeletons. AB - The blood-testis barrier (BTB) is an important ultrastructure in the testis that supports meiosis and postmeiotic spermatid development since a delay in the establishment of a functional Sertoli cell barrier during postnatal development in rats or mice by 17-20 day postpartum (dpp) would lead to a delay of the first wave of meiosis. Furthermore, irreversible disruption of the BTB by toxicants also induces infertility in rodents. Herein, we summarize recent findings that BTB dynamics (i.e., disassembly, reassembly, and stabilization) are supported by the concerted efforts of the actin- and microtubule (MT)-based cytoskeletons. We focus on the role of two actin nucleation protein complexes, namely, the Arp2/3 (actin-related protein 2/3) complex and formin 1 (or the formin 1/spire 1 complex) known to induce actin nucleation, respectively, by conferring plasticity to actin cytoskeleton. We also focus on the MT plus (+)-end tracking protein (+TIP) EB1 (end-binding protein 1) which is known to confer MT stabilization. Furthermore, we discuss in particular how the interactions of these proteins modulate BTB dynamics during spermatogenesis. These findings also yield a novel hypothetical concept regarding the molecular mechanism that modulates BTB function. PMID- 29453577 TI - Computational Methods Involved in Evaluating the Toxicity of the Reproductive Toxicants in Sertoli Cell. AB - The Sertoli cell, the somatic component of seminiferous tubule, provides nutritional support and immunological protection and supports overall growth and division of germ cells. Cytoskeletons, junction proteins, and kinases in Sertoli cells are prime targets for reproductive toxicants and other environmental contaminants. Among the varied targets, the kinases that are crucial for regulating varied activities in spermatogenesis such as assembly/disassembly of blood-testis barrier and apical ES and those that are involved in conferring polarity are highly targeted. In an attempt to study the effect of toxicants on these kinases, the present chapter deals with computational methodology concerning their three-dimensional structure prediction, identification of inhibitors, and understanding of conformational changes induced by these inhibitors. PMID- 29453576 TI - Monitoring the Integrity of the Blood-Testis Barrier (BTB): An In Vivo Assay. AB - The blood-testis barrier is a unique ultrastructure in the mammalian testis, located near the basement membrane of the seminiferous tubule that segregates the seminiferous epithelium into the basal and the adluminal (apical) compartment. Besides restricting paracellular and transcellular passage of biomolecules (e.g., paracrine factors, hormones), water, electrolytes, and other substances including toxicants and/or drugs to enter the adluminal compartment of the epithelium, the BTB is an important ultrastructure that supports spermatogenesis. As such, a sensitive and reliable assay to monitor its integrity in vivo is helpful for studying testis biology. This assay is based on the ability of an intact BTB to exclude the diffusion of a small molecule such as sulfo-NHS-LC-biotin (C20H29N4NaO9S2, Mr. 556.59, a water-soluble and membrane-impermeable biotinylation reagent) from the basal to the apical compartment of the seminiferous epithelium. Herein, we summarize the detailed procedures on performing the assay and to obtain semiquantitative data to assess the extent of BTB damage when compared to positive controls, such as treatment of rats with cadmium chloride (CdCl2) which is known to compromise the BTB integrity. PMID- 29453578 TI - A Stopped-Flow Light Scattering Methodology for Assessing the Osmotic Water Permeability of Whole Sertoli Cells. AB - Movement of water into and out of the cell is fundamental to life. In the male reproductive tract, at the level of the seminiferous epithelium, Sertoli cells are pivotal in mediating the movement of water into the luminal compartment, a process providing a means of transport of spermatozoa into the epididymal ducts. Here, we describe a stopped-flow light-scattering methodology to easily assess the Sertoli cell osmotic water permeability. The devised methodology is well suited for studying how the Sertoli cell's permeability changes following exogenous stimuli. PMID- 29453579 TI - Cryopreservation of Human Testicular Tissue by Isopropyl-Controlled Slow Freezing. AB - Tissue cryopreservation uses very low temperatures to preserve structurally intact living cells in their natural microenvironment. Cell survival is strongly influenced by the biophysical effects of ice during both the freezing and the subsequent thawing. These effects can be controlled by optimizing the fragment size, type of cryoprotectant, and cooling rate. The challenge is to determine cryopreservation parameters that suit all cell types present in the tissue. Here we describe a quick and convenient protocol for the cryopreservation of testicular tissue using an isopropyl-insulated freezing device, which was validated in both a mouse and a human model. PMID- 29453580 TI - Neurosurgical management of hydrocephalus by a general surgeon in an extremely low resource setting: initial experience in North Kivu province of Eastern Democratic Republic of Congo. AB - PURPOSE: Evaluate the management of hydrocephalus in pediatric patients in the Eastern Democratic Republic of Congo by a general surgeon. METHODS: Retrospective review of a single institution in the province of North Kivu. Patient charts and surgical notes were reviewed from 2003 to 2016. RESULTS: 116 procedures were performed for an average of 8.9 per year. 51.7% of surgeries were on female patients with an average age of 13.6 +/- 22.7. The average distance traveled from home to hospital was 153.7 km but ranged from 5 to 1420 km. The majority of hydrocephalus was due to neonatal sepsis (57%); 33.6% were classified as congenital; 9.5% of cases followed myelomeningocele closure. 97.4% had a ventriculoperitoneal (VP) shunt placed. Endoscopic third ventriculostomy combined choroid plexus cauterization (ETV/CPC) was performed in 2.5% of patients. Shunt infection occurred in 9.5% of patients, shunt dysfunction or obstruction in 5.2% and shunt exteriorization in 1.7%; no complications occurred in patients who underwent ETV/CPC. CONCLUSION: VP shunt is the predominant management for hydrocephalus in this environment with increasing use of ETV/CPC. Further research is needed to evaluate variability by etiology, short and long-term outcomes of procedures performed by neurosurgeons and general surgeons, and regional epidemiologic variability. PMID- 29453581 TI - Health-related quality of life in children born with congenital diaphragmatic hernia. AB - PURPOSE: The aim of this study was to examine health-related quality of life (HRQoL) in children born with congenital diaphragmatic hernia (CDH). METHODS: Between 1993 and 2003, a total of 102 children born with CDH were treated at Astrid Lindgren Children's hospital in Stockholm. In 2012, long-term survivors (n = 77) were asked to participate in the present study, which resulted in a 46% (n = 35) response rate. The KIDSCREEN-52 questionnaire was used for measuring HRQoL and a detailed review of medical records was performed. RESULTS: The study participants did not differ from the non-participants in terms of prenatal diagnosis, gender, side of lesion, method of surgical repair, time to intubation, need for ECMO support, or way of discharge from the hospital. Children born with CDH considered themselves to have a good HRQoL, as good as healthy Swedish children. There were only a few significant HRQoL differences within the group of children with CDH, although several median scores in ECMO-treated patients were somewhat lower. Correlations between child and parent scores on HRQoL were low. CONCLUSIONS: Health-related quality of life in children born with CDH is good overall, however, a correlation between the severity of the malformation and HRQoL cannot be excluded. PMID- 29453582 TI - The clinical phenotype of patients positive for antibodies to myositis and myositis-related disorders. AB - Inflammatory myopathies are a clinically diverse group of diseases, in which the detection of particular autoantibodies may facilitate diagnosis, treatment, and prognosis. The aim of this report is to summarize our experience with specific autoantibody testing in patients with inflammatory myopathies. Data were collected over the last decade in the Autoimmune Center of the Sheba Medical Center, a tertiary referral hospital. Data regarding patients' positive for autoantibodies against Jo-1, PL-7, PL-12, SRP, Mi-2, Ku, and PM-Scl antigens were retrospectively collected. Patient demographics, clinical characteristics, and mortality were recorded. Descriptive statistics (mean, standard deviation, frequency, and percentage) were calculated. A total of 507 patients were surveyed for sclero-poly-synthetase antibodies, as part of the diagnostic workup of myositis/myalgia or interstitial lung disease. Forty-three patients were found positive for one or more of the abovementioned antibodies, and 23 of them (53.49%) had interstitial lung disease (ILD). Four patients were positive for anti-PL-7, three of them had ILD and Raynaud's phenomenon. Five patients were positive for anti-Ku, and four of them had both arthritis and Raynaud's phenomenon. Nine patients were positive for anti-Mi-2, and six of them were given diagnosed with dermatomyositis. Ten patients were positive for anti-SRP, and six of them had cancers of various types. Our results reiterate the previously recognized associations between anti-Mi-2 and dermatomyositis, anti-Ku and Raynaud's phenomenon, and between anti-PL-7 and ILD. In addition, our data support an association between anti-SRP autoantibody positivity and malignancy, which calls for further investigation. PMID- 29453583 TI - Reconstruction for chronic Achilles tendinopathy: comparison of flexor hallucis longus (FHL) transfer versus V-Y advancement. AB - BACKGROUND: Several operative techniques exist for Achilles tendinopathy. The purpose of our study was to compare the clinical and functional outcomes of flexor hallucis longus (FHL) transfer and V-Y advancement for the treatment of chronic insertional Achilles tendinopathy. METHODS: Retrospective chart review from 2010 to 2016 of patients that underwent FHL transfer or V-Y advancement for chronic insertional Achilles tendinopathy. Outcome measures were compared for these two procedures. RESULTS: In total, 46 patients (49 ankles) with a mean age of 55.0 (range 33-73) years. Mean follow-up time 44.7 +/- 25.5 months. FHL group had 21 patients (21 ankles) with 89% satisfaction, 14% complication rate, final VAS of 0.4, final VISA-A of 89.1, subjective strength improvement following surgery of 78%, and 94% would recommend the procedure. V-Y group had 25 patients (28 ankles) with 74% subjective satisfaction, 21% complication rate, final VAS of 1.4, final VISA-A of 78.4, subjective strength improvement following surgery of 67%, and 84% would recommend the procedure. There was no significant difference in any of the results rates between the two groups (p > .05). CONCLUSION: V-Y advancement is comparable to FHL transfer for the operative management of insertional Achilles tendinopathy. Though our results trend towards less satisfactory results following V-Y advancement, we found high satisfaction rates with similar functional outcomes and complication rates in both operative groups. We suggest considering V-Y advancement as a viable option for the primary treatment of chronic insertional Achilles tendinopathy in patients who may not be an ideal candidate for FHL transfer. PMID- 29453584 TI - Variations in the attachments of the medial meniscal anterior horn: a descriptive cadaveric study. AB - PURPOSE: Meniscal tears are common in Kenya, with prevalence rates ranging from 45 to 78% of intracapsular knee pathology. Diagnosis of these injuries relies on the use of both clinical signs and symptoms as well as radiological investigations. In a few instances, radiological detection could be difficult, partly because of variant attachment patterns of the medial meniscal anterior horn. Some of these unusual attachments of the anterior horn of the medial meniscus could even be mistaken for meniscal tears. There is also evidence that these variations differ from population to population. This study, therefore, aimed to determine the variant bony and ligamentous attachments of the medial meniscal anterior horn in a sample Kenyan population. METHODS: The study was conducted at the Department of Human Anatomy, University of Nairobi. Thirty-one male and female unpaired medial menisci were obtained from cadaveric specimen. The bony and ligamentous attachments were identified and recorded and photomacrographs taken. RESULTS: The bony attachments different from the classical textbook attachment accounted for 54.8% of the medial meniscal anterior horns. The anterior intermeniscal ligament was present in 62.3% while 16.2% showed attachment to the anterior cruciate ligament. Twenty-nine percent (29%) of the medial menisci studied did not have any ligamentous attachments. CONCLUSIONS: The bony and ligamentous attachments of the medial meniscal anterior horn are highly variable presenting unique diagnostic and therapeutic challenges. A new classification of ligamentous attachments is thus proposed. PMID- 29453585 TI - Predicting hospital length of stay and short-term function after hip or knee arthroplasty: are both performance and comorbidity measures useful? AB - PURPOSE: Variations in hospital length of stay (LOS) and function are present after hip or knee arthroplasty. Comorbidity and performance measures have been associated with post-operative outcomes. It is however not known if both independently contribute to outcome prediction. The objective of this study was to evaluate the combined predictive ability of comorbidity scores (American Society of Anesthesiologists classification system (ASA), Charlson comorbidity index (CCI), 2008 version of the CCI (CCI08)) and a performance measure (Timed-Up and-Go (TUG)) on LOS and short-term function in patients undergoing knee or hip arthroplasty. METHODS: One hundred eight patients undergoing hip or knee arthroplasty were assessed preoperatively with the ASA, CCI, CCI08, and TUG. LOS was determined through administrative data. The Older Americans Resources and Services ADL questionnaire (OARS) was used to assess function two and six weeks after surgery. Logistic regression was used to assess the relationship between pre-operative assessments and LOS and OARS scores. RESULTS: Both the ASA and TUG significantly contributed to LOS prediction. Odds ratio (OR) was 3.57 (95% confidence interval (CI) 1.26-10.07) for the ASA, and 2.18 (95% CI 1.67-4.15) for a one-standard deviation (SD) increase of 4.45 s of the TUG. Only the TUG was predictive of two weeks function and trending towards significance for six weeks function. One SD TUG increase yielded an OR of 2.14 (95% CI 1.53-3.79) for two week function. CONCLUSIONS: The TUG and ASA can be used pre-operatively in combination to predict LOS, and TUG can also be used to predict short-term post operative function.

AB - AIM: The aim of this study is to demonstrate the varying rules of radiographic angles following varying three-dimensional (3D) orientations and locations of cup using an accurate mathematical model. METHODS: A cone model is established to address the quantitative relationship between the opening circle of cup and its ellipse projection on radiograph. The varying rules of two-dimensional (2D) radiographic anteversion (RA) and inclination (RI) angles can be analyzed. RESULTS: When the centre of cup is located above X-ray source, with proper 3D RI/RA angles, 2D RA angle can be equal to its 3D counterpart, and 2D RI angle is usually greater than its 3D counterpart. Except for the original point on hip centered anterior-posterior radiograph, there is no area on radiograph where both 2D RA and RI angles are equal to their 3D counterparts simultaneously. DISCUSSION: This study proposes an innovative model for accurately explaining how 2D RA/RI angles of cup are varying following different 3D RA/RI angles and location of cup. The analysis results provide clinicians an intuitive grasp of knowledge about 2D RA/RI angles greater or smaller than their 3D counterparts post-operatively. The established model may allow determining the effects of pelvic rotations on 2D radiographic angles of cup. PMID- 29453587 TI - Trimorphic extreme clubfoot deformities and their management by triple surgical skin expanders- DOLAR, DOLARZ and DOLARZ-E (evidence based mega-corrections without arthrodesis). AB - AIM/PURPOSE: Extreme congenital club foot deformities are common in developing countries, presenting at birth, persisting in children, adolescents and adults; as untreated/under-corrected by conservative and/or surgical means. Scores of confusing names exist in literature for such deformities with no good treatment available; mostly advocating unacceptable arthrodesis. The author researched this grey area for more than 40 years and successfully innovated improved surgical corrections, more acceptable to patients. METHODS: All were given a generic name: "extreme deformities", with 3 hierarchic grades. each 3D (trimorphic) because of their common aim: a good correction. The author started with anatomical dissections in clubfeet (zero cost), consistently reinforced with solid clinical background. Heterogeneous skin contractures, congenital with/without scars, were discovered as the primary cause with cramped deeper tissues and evolved, evidence based, 3D enlargement of skin chamber by triple expanding incisions: DOrso LAteral Rotation skin flap (DOLAR- acronym) for grade I, DOLAR + Z-plasty (DOLARZ) for grade II and DOLAR + Z + VY-plasty (DOLARZ-E) for grade III, E means Extended. Patient satisfaction level (excellent, good, fair/poor) had been considered for grading results, rather than scoring systems because each clubfoot is different with countless variables. RESULTS & CONCLUSIONS: The author operated 1080 feet during the last 40 years with long term follow up, six months to 30 years, with an average of 121/2 years. The results obtained were: excellent/good (96%) and fair/poor (4% including superficial skin necrosis only in 3%, evidence based). Triple surgical skin expansion consistently resulted in longer, flexible, joints sparing, good shaped, better functioning foot; even in adults. PMID- 29453588 TI - Problem and Pathological Gambling in Schizophrenia: Exploring Links with Substance Use and Impulsivity. AB - High rates of both problem and pathological gambling (PPG) and substance-use disorders (SUDs) have been reported in schizophrenia, and yet PPG frequently goes undetected in clinical practice and unexamined in research. Here, we aimed to examine the relationship between PPG and SUDs in a large sample of patients across several factors related to both gambling and substance use, including poly substance use. Additionally, delay discounting is a form of impulsivity known to positively associate with both PPG and SUDs and thought to underlie mechanisms of addiction in both contexts. We aimed to investigate the relationship between PPG and delay discounting in schizophrenia. 337 individuals with schizophrenia completed structured face-to-face interviews regarding gambling behaviors, substance use, and delay discounting. PPG in schizophrenia was associated with substance use, in particular with poly-substance use, and with delay discounting among males. Factors related to substance use were strongly linked with gambling in this sample, but not always with PPG more than recreational gambling. Our findings overall support the notions that multiple forms of gambling in schizophrenia are clinically relevant, that gambling may share common substrates with substance use, and that delay discounting represents a potential mechanism of this association in males. PMID- 29453590 TI - Attribution of weight regain to emotional reasons amongst European adults with overweight and obesity who regained weight following a weight loss attempt. AB - PURPOSE: Despite the wide availability of effective weight loss programmes, maintenance of weight loss remains challenging. Difficulties in emotion regulation are associated with binge eating and may represent one barrier to long term intervention effectiveness in obesity. The purpose of this study was to determine the relationship between emotion regulation difficulties and the extent of weight regain in a sample of adults who had lost, and then regained, weight, and to examine the characteristics associated with emotional difficulties. METHODS: 2000 adults from three European countries (UK, Portugal, and Denmark) completed an online survey assessing self-reported weight loss and regain following their most recent weight loss attempt. They also completed a binge eating disorder screening questionnaire and, if they had regained weight, were asked if they attributed it to any emotional factors (a proxy for emotion regulation difficulties). Spearman's correlations and logistic regression were used to assess the associations between emotion regulation, weight regain, and strategy use. RESULTS: Emotion regulation difficulties were associated with greater weight regain (N = 1594 who lost and regained weight). Attribution to emotional reasons was associated with younger age, female gender, loss of control and binge eating, lower perceptions of success at maintenance, using more dietary and self-regulatory strategies in weight loss, and fewer dietary strategies in maintenance. CONCLUSIONS: Weight-related emotion regulation difficulties are common amongst regainers and are associated with regaining more weight. Affected individuals are already making frequent use of behavioural strategies during weight loss, but do not apply these consistently beyond active attempts. Simply encouraging the use of more numerous strategies, without concurrently teaching emotion regulation skills, may not be an effective means to improving weight outcomes in this group. LEVEL OF EVIDENCE: Level V, descriptive (cross-sectional) study. PMID- 29453591 TI - Emotional intelligence, empathy and alexithymia in anorexia nervosa during adolescence. AB - PURPOSE: Socio-emotional difficulties have been observed on adult patients suffering from anorexia nervosa (AN). But researches with adolescents are scarce and non-congruent. The aim of this paper is to identify the socio-emotional difficulties that are encountered by AN during adolescence, and to isolate them from those encountered by control adolescents. METHOD: 41 AN and 38 control adolescents were assessed using the emotional quotient inventory by Bar-On, youth version (EQ-i: YV), the Toronto Alexithymia Questionnaire (TAS-20), the Interpersonal Reactivity Index (IRI), and anxiety and depression were controlled using the Hospital Anxiety and Depression Scale (HADS). RESULTS: Personal distress remains the main difference between the two groups, even when depression and anxiety are controlled. Intrapersonal difficulties are observed in the AN group, as well as alexithymic traits. CONCLUSION: Research on AN has to focus on the socio-emotional difficulties during adolescence, to properly identify which difficulties are linked to that life period, and which are a trait of AN. LEVEL III: Evidence obtained from well-designed cohort or case-control analytic studies, preferably from more than one center or research group. PMID- 29453589 TI - Validity of triglyceride-glucose index as an indicator for metabolic syndrome in children and adolescents: the CASPIAN-V study. AB - PURPOSE: The purpose of this study was to determine the cut-off values of triglycerides and glucose (TyG) index as one of the indirect indices for metabolic syndrome (MetS) in a pediatric population. METHODS: This national study was conducted in 2015 on 14400 students, aged 7-18 years. They were selected by random cluster sampling from 30 provinces of our country during the fifth survey of a national school-based surveillance program. MetS was defined based on the Adult Treatment Panel III (ATP III) criteria modified for the pediatric age group. The cut-off values of TyG index for MetS were obtained using the receiver operation characteristic (ROC) curve analysis by gender and age groups. RESULTS: Totally, 3843 students (52.3% boys) with mean (SD) age of 12.45 (3.04) years were assessed. The area under the ROC curve of TyG index for MetS was 0.83 in total participants. According to the ATP III criteria the cut-off values of the TyG index were 8.33 (8.21-8.45) in total students, 8.47 (8.36-8.58) in boys, and 8.33 (8.18-8.48) in girls. In the 7-12 and 13-18 years' age groups, these values were 8.47 (8.32-8.63) and 8.34 (8.22-8.45) in total, 8.39 (8.26-8.52) and 8.47 (8.33 8.61) in boys, 8.33 (8.11-8.55) and 8.35 (8.22-8.47) in girls, respectively. CONCLUSION: The findings of this study can be clinically helpful for screening MetS in children and adolescents but the effectiveness of these criteria needs to be evaluated by further longitudinal surveys. LEVEL OF EVIDENCE: Level V, cross sectional descriptive study (National surveillance study). PMID- 29453592 TI - Patient-specific registration of 3D CT angiography (CTA) with X-ray fluoroscopy for image fusion during transcatheter aortic valve implantation (TAVI) increases performance of the procedure. AB - OBJECTIVES: The aim of this study was to adapt patient-specifically a co registration procedure for image fusion (IF) of a pre-interventional CT dataset with real-time X-ray (XR) fluoroscopy during transfemoral transcatheter aortic valve implantation (TAVI), enabling improved performance of the procedure. BACKGROUND: The ability to use 3D models of the respective anatomies to complement the anatomic information obtained by XR fluoroscopy and provide a greater degree of real-time anatomical guidance holds great potential for complex cardiac interventions, especially for TAVI procedures with cerebral protection. METHODS: Initial registration of two datasets was performed during the femoral puncture and sheath introduction using routinely acquired arteriographies. On time refinement of the co-registration was then performed during the on-going procedure avoiding additional angiograms for the co-registration. Performance of the method was evaluated quantitatively in terms of procedural characteristics and clinical events. RESULTS: Significant reduction of the radiation dose [51 (42 55) vs. 64 (49-81) Gy cm2, p = 0.032] and contrast agent (CA) volume [80 (50-95) vs. 100 (80-110) ml, p = 0.010] was achieved with the optimized approach as compared to the control group without IF, with simultaneous decrease of procedural [48 (41-58) vs. 61 (53-67) min, p = 0.002] and fluoroscopy times [14.8 (12.7-18.5) vs. 17.8 (14.3-19.4), p = 0.108]. CONCLUSIONS: In this proof-of concept study we have demonstrated a novel co-registration approach for IF during TAVI not requiring any additional CA or XR scan. We have evaluated its potential benefit with the strong focus on guiding the femoral puncture, placement of the double-filter cerebral embolic protection device, and deployment of the valve prosthesis. We achieved improved performance and safety of the procedure with the introduced approach. PMID- 29453593 TI - Risk marker profiles in patients treated with percutaneous septal ablation for symptomatic hypertrophic obstructive cardiomyopathy. AB - BACKGROUND AND STUDY OBJECTIVE: Different studies have shown a good long-term survival with improvement of symptoms and hemodynamics after percutaneous septal ablation (PTSMA), similar to myectomy considered to be the therapeutic "gold standard" for symptomatic hypertrophic obstructive cardiomyopathy (HOCM). Furthermore, desobliteration of left ventricular (LV) outflow may modify features of the disease considered to be risk-relevant, such as magnitude of LV hypertrophy, outflow gradient, and left atrial (LA) size. The aim oft this study was to examine predictors of long-term mortality in a large cohort of patients with HOCM treated with PTSMA. METHODS AND RESULTS: 497 consecutive patients with symptomatic HOCM (mean age 55.4 +/- 14.4 years, NYHA class: 2.9 +/- 0.4) who underwent PTSMA between 1996 and 2014 were studied. Periprocedural mortality was 1% (five patients). During a follow-up time of 64.5 +/- 53.2 months (range 0.1 207), 51 patients died, of these 25 due to cardiovascular problems, while 26 deaths were attributed to non-cardiac causes. Overall survival rates were 89.4% (+/- 1.7) after 5 and 80.6% (+/- 2.7) after 10 years. Among the baseline variables, advanced age, recurrent syncope, and magnitude of LV thickening were risk markers correlated to long-term post-procedural survival. The only mortality predictor that could be identified during follow-up was post-procedural NYHA class. Neither the other classical HCM risk markers nor other clinical or echocardiographic parameters predicted cardiac or all-cause mortality in this cohort. CONCLUSIONS: Our findings suggest that the risk profile after septal ablation may differ from that of HOCM patients without an outflow desobliteration. PMID- 29453594 TI - Time-to-first-event versus recurrent-event analysis: points to consider for selecting a meaningful analysis strategy in clinical trials with composite endpoints. AB - BACKGROUND: Composite endpoints combining several event types of clinical interest often define the primary efficacy outcome in cardiologic trials. They are commonly evaluated as time-to-first-event, thereby following the recommendations of regulatory agencies. However, to assess the patient's full disease burden and to identify preventive factors or interventions, subsequent events following the first one should be considered as well. This is especially important in cohort studies and RCTs with a long follow-up leading to a higher number of observed events per patients. So far, there exist no recommendations which approach should be preferred. DESIGN: Recently, the Cardiovascular Round Table of the European Society of Cardiology indicated the need to investigate "how to interpret results if recurrent-event analysis results differ [...] from time-to-first-event analysis" (Anker et al., Eur J Heart Fail 18:482-489, 2016). This work addresses this topic by means of a systematic simulation study. METHODS: This paper compares two common analysis strategies for composite endpoints differing with respect to the incorporation of recurrent events for typical data scenarios motivated by a clinical trial. RESULTS: We show that the treatment effects estimated from a time-to-first-event analysis (Cox model) and a recurrent-event analysis (Andersen-Gill model) can systematically differ, particularly in cardiovascular trials. Moreover, we provide guidance on how to interpret these results and recommend points to consider for the choice of a meaningful analysis strategy. CONCLUSIONS: When planning trials with a composite endpoint, researchers, and regulatory agencies should be aware that the model choice affects the estimated treatment effect and its interpretation. PMID- 29453595 TI - Cardio-oncology: conflicting priorities of anticancer treatment and cardiovascular outcome. AB - BACKGROUND: This article about the emerging field of cardio-oncology highlights typical side effects of oncological therapies in the cardiovascular system, cardiovascular complications of malignancies itself, and potential preventive or therapeutic modalities. METHODS: We performed a selective literature search in PubMed until September 2016. RESULTS: Cardiovascular events in cancer patients can be frequently attributed to oncological therapies or to the underlying malignancy itself. Furthermore, many patients with cancer have pre-existing cardiovascular diseases that can be aggravated by the malignancy or its therapy. Cardiovascular abnormalities in oncological patients comprise a broad spectrum from alterations in electrophysiological, laboratory or imaging tests to the occurrence of thromboembolic, ischemic or rhythmological events and the impairment of left ventricular function or manifest heart failure. DISCUSSION: A close interdisciplinary collaboration between oncologists and cardiologists/angiologists as well as an increased awareness of potential cardiovascular complications could improve clinical care of cancer patients and provides a basis for an improved understanding of underlying mechanisms of cardiovascular morbidity. PMID- 29453599 TI - Sequential analysis in neonatal research-systematic review. AB - : As more new drugs are discovered, traditional designs come at their limits. Ten years after the adoption of the European Paediatric Regulation, we performed a systematic review on the US National Library of Medicine and Excerpta Medica database of sequential trials involving newborns. Out of 326 identified scientific reports, 21 trials were included. They enrolled 2832 patients, of whom 2099 were analyzed: the median number of neonates included per trial was 48 (IQR 22-87), median gestational age was 28.7 (IQR 27.9-30.9) weeks. Eighteen trials used sequential techniques to determine sample size, while 3 used continual reassessment methods for dose-finding. In 16 studies reporting sufficient data, the sequential design allowed to non-significantly reduce the number of enrolled neonates by a median of 24 (31%) patients (IQR - 4.75 to 136.5, p = 0.0674) with respect to a traditional trial. When the number of neonates finally included in the analysis was considered, the difference became significant: 35 (57%) patients (IQR 10 to 136.5, p = 0.0033). CONCLUSION: Sequential trial designs have not been frequently used in Neonatology. They might potentially be able to reduce the number of patients in drug trials, although this is not always the case. What is known: * In evaluating rare diseases in fragile populations, traditional designs come at their limits. About 20% of pediatric trials are discontinued, mainly because of recruitment problems. What is new: * Sequential trials involving newborns were infrequently used and only a few (n = 21) are available for analysis. * The sequential design allowed to non-significantly reduce the number of enrolled neonates by a median of 24 (31%) patients (IQR - 4.75 to 136.5, p = 0.0674). PMID- 29453600 TI - Argininosuccinate Synthetase-1 (ASS1) Loss in High-Grade Neuroendocrine Carcinomas of the Urinary Bladder: Implications for Targeted Therapy with ADI-PEG 20. AB - High-grade neuroendocrine carcinomas (HGNECs) of the urinary bladder encompass small cell (SCNEC) and large cell neuroendocrine carcinomas (LCNEC). Currently, recommended initial management is with systemic chemotherapy, followed by consolidative therapy with either radical cystectomy or radiotherapy in patients with localized disease. Nevertheless, survival in this setting remains poor. We therefore evaluated the potential to modify arginine metabolism as an alternative, targeted therapy approach in these carcinomas. In humans, arginine is a semi-essential amino acid and its synthesis enzyme argininosuccinate synthetase (ASS1) represents the rate-limiting step in arginine biosynthesis. Neoplasms that show low to absent ASS1 expression require extracellular arginine for cancer cell survival, and thus can be targeted using arginine-degrading enzymes such as pegylated arginine deiminase (ADI-PEG 20). An initial study by our group of 19 patients demonstrated that a high percentage of SCNEC lack ASS1 expression. Herein, we evaluated an expanded cohort of 74 radical cystectomy patients with HGNEC, including 63 SCNEC, 5 LCNEC, and 6 mixed morphology HGNEC patients. ASS1 expression was assessed through immunohistochemistry. Fifty-eight (of 74, 78%) patients with HGNEC showed absent ASS1 expression, including all patients with LCNEC and mixed morphology (11 of 11, 100%). Ten-year survival from disease-specific death was not statistically significant between ASS1-expressing and ASS1-deficient cases (p = 0.75). Our results show that HGNEC of the bladder may be candidates for arginine deprivation therapy using drugs such as ADI-PEG 20. Further studies are needed to validate these findings and to determine the therapeutic efficacy of such agents. PMID- 29453596 TI - Effectiveness of the sesquiterpene (-)-alpha-bisabolol in dogs with naturally acquired canine leishmaniosis: an exploratory clinical trial. AB - The use of natural products is a promising approach for treating visceral leishmaniosis. (-)-alpha-Bisabolol is a sesquiterpene that have been proved active in vivo on Leishmania infantum-infected mice without showing toxicity. A single-centre, parallel-group, randomized, exploratory study was designed to assess its efficacy in a canine leishmaniosis model involving naturally infected dogs. In this clinical trial, 12 dogs were allocated into two groups and were treated with either meglumine antimoniate (100 mg/kg) through subcutaneous route or (-)-alpha-bisabolol (30 mg/kg) through oral route for two treatment series of 30 days, separated by a 30-day interval. A 4-month follow-up period was established as well. Parasite loads in bone marrow, lymph node and blood were estimated through quantitative PCR. Antibody titres were determined through immunofluorescence antibody test and cytokine expression values were estimated through real-time reverse transcription-PCR. Treatment safety was assessed through the evaluation of weight, gastrointestinal alterations and hematological and biochemical parameters in blood. Analyses were performed before and after treatment, and after a 4-months follow-up period. Treatment with the sesquiterpene was effective at decreasing parasite loads and increasing gamma interferon expression level. Dogs treated with (-)-alpha-bisabolol did not show any toxicity sign. These results were better than those obtained using the reference drug, meglumine antimoniate. The natural compound seemed to induce a Th1 immune response that led to parasitological and clinical improvement without showing any safety issue, suggesting a high potential for the treatment of canine and human visceral leishmaniosis. PMID- 29453602 TI - Tight software, methodological/physiological variation, less so. PMID- 29453601 TI - Immunohistochemical Biomarkers in Pituitary Pathology. AB - Pituitary pathology is one area of endocrine pathology that is highly dependent on immunohistochemistry. There is a wide range of disorders that occur in and around the sella turcica, and the distinction of tumor-like lesions from neoplasms requires careful evaluation. The diagnosis, prognosis, and predictive features of neoplasms in the sellar region are all dependent on the application and interpretation of biomarkers of cell differentiation, hormonal activity, subcellular morphology, and proliferation. As in hematopathology, the number of biomarkers has increased dramatically and continues to increase. Fortunately, some of the biomarkers provide information that was initially dependent on electron microscopy; therefore, the need for this additional technology has been reduced to only rare unusual tumors. In this review, we provide a simple approach to understanding the importance of the various biomarkers that are used to ensure the correct diagnosis and provide the treating clinicians with tools to guide appropriate patient management and surveillance. PMID- 29453603 TI - Repeatable and reproducible measurements of myocardial oxidative metabolism, blood flow and external efficiency using 11C-acetate PET. AB - BACKGROUND: Non-invasive approaches to investigate myocardial efficiency can help track the progression of heart failure (HF). This study evaluates the repeatability and reproducibility of 11C-acetate positron emission tomography (PET) imaging of oxidative metabolism. METHODS AND RESULTS: Dynamic 11C-acetate PET scans were performed at baseline and followup (47 +/- 22 days apart) in 20 patients with stable HF with reduced ejection fraction. Two observers blinded to patients' clinical data used FlowQuant(r) to evaluate test-retest repeatability, as well as intra- and inter-observer reproducibility of 11C-acetate tracer uptake and clearance rates, for the measurement of myocardial oxygen consumption (MVO2), myocardial external efficiency (MEE), work metabolic index (WMI), and myocardial blood flow. Reproducibility and repeatability were evaluated using intra-class correlation (ICC) and Bland-Altman coefficient-of-repeatability (CR). Test-retest correlations and repeatability were better for MEE and WMI compared to MVO2. All intra- and inter-observer correlations were excellent (ICC = 0.95-0.99) and the reproducibility values (CR = 3%-6%) were significantly lower than the test-retest repeatability values (22%-54%, P < 0.001). Repeatability was improved for all parameters using a newer PET-computed tomography (CT) scanner compared to older PET-only instrumentation. CONCLUSION: 11C-acetate PET measurements of WMI and MEE exhibited excellent test-retest repeatability and operator reproducibility. Newer PET-CT scanners may be preferred for longitudinal tracking of cardiac efficiency. PMID- 29453604 TI - Evaluating the impact of spirituality on the quality of life, anxiety, and depression among patients with cancer: an observational transversal study. AB - OBJECTIVE: Spiritual well-being was found to have some protective effect against end-of life despair in cancer patients. We aimed at assessing the impact of spirituality on the quality of life, depression, and anxiety of Lebanese cancer patients. METHODS: Our observational transversal monocentric study was conducted between January and April 2016 among a convenient sample of 115 Lebanese cancer patients admitted to Hotel-Dieu de France Hospital (HDF), Beirut-Lebanon. In addition to socio-demographic and clinical data, three questionnaires were used: EORTC QLQ-C30 (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, 3rd version), FACIT-Sp-12 (Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being; The 12-item Spiritual Well-Being Scale, 4th version), and HADS (Hospital Anxiety and Depression Scale). Eighteen patients taking anxiolytic and/or antidepressants were not included in the analysis. The remaining 97 patients were analyzed. RESULTS: Better emotional and cognitive functioning was seen in patients with higher meaning, peace, faith, and total FACIT scores. Meaning, peace, and total FACIT scores were also higher among patients with better global health status and quality of life. Anxiety as well as depression was significantly associated to all spiritual well-being factors. CONCLUSION: Spirituality can improve quality of life and decrease the incidence of anxiety and depression in cancer patients. Our results highlight the need to incorporate spiritual care in healthcare systems. PMID- 29453605 TI - Enhanced recovery after surgery-ERAS-principles, practice and feasibility in the elderly. AB - This is a short overview of the principles of a novel development in surgery called enhanced recovery after surgery (ERAS) programs. This is an evidence-based approach to perioperative care that has shown to reduce complications and recovery time by 30-50%. The main mechanism is reduction of the stress reactions to the operation. These principles have been shown to be particularly well suited for the compromised patient and hence very good for the elderly people who often have co-morbidities and run a higher risk of complications.

PMID- 29453607 TI - Semaphorin 7A in circulating regulatory T cells is increased in autosomal dominant polycystic kidney disease and decreases with tolvaptan treatment. AB - BACKGROUND: Semaphorin 7A (SEMA7A) is an immunomodulating protein implicated in lung and liver fibrosis. In autosomal-dominant polycystic kidney disease (ADPKD), the progressive expansion of renal cysts, inflammation, and subsequent renal fibrosis leads to end-stage renal disease (ESRD). SEMA7A may play a role in renal fibrosis and in ADPKD. METHODS: We evaluated Sema7a in a mouse model of renal fibrosis and determined the expression of SEMA7A in human ADPKD kidney. We analyzed SEMA7A expression on peripheral blood mononuclear cells (PBMCs), including CD45+ (leukocyte), CD14+(monocyte), CD4+ (T lymphocytes) and CD4+Foxp3+CD25+ [regulatory T lymphocytes (Tregs)] from 90 ADPKD patients (11 tolvaptan treated and 79 tolvaptan naive), and 21 healthy volunteers, using a Fluorescence-Activated Cell Sorting (FACS). RESULTS: Sema7a is required for renal fibrosis. SEMA7A shows robust expression in ADPKD kidneys, localizing to cysts derived from distal tubules. SEMA7A is higher in circulating monocytes, but unchanged in CD4+ lymphocytes in ADPKD patients. The SEMA7A increase was detected early (stage 1 CKD) and seemed more prominent in patients with smaller kidneys (p = 0.09). Compared to tolvaptan-naive ADPKD patients, those treated with tolvaptan showed reduced SEMA7A expression on monocytes, T lymphocytes, and Tregs, although the number of PBMCs was unchanged. After 1 month of tolvaptan treatment, SEMA7A expression on Tregs decreased. CONCLUSIONS: SEMA7A shows potential as both a therapeutic target in mammalian kidney fibrosis and as a marker of inflammation in ADPKD patients. SEMA7A expression was lower after tolvaptan treatment, which may reflect drug efficacy. PMID- 29453609 TI - Leptin receptor gene (A/G) polymorphism rs1137101 and renal cell carcinoma. AB - Leptin plays an important role in carcinogenesis as leptin/leptin receptor signaling promotes the angiogenesis, proliferation, and inhibits epithelial cell apoptosis. Variants in the leptin receptor gene have potential associations with renal cell carcinoma (RCC). We aimed to investigate association of rs1137101 (A/G) polymorphism at LEPR gene with risk of RCC and patients survival. 123 individuals were classified into group I: 73 RCC patients and group II: 50 healthy controls. Genotyping of the Gln223Arg (A/G) polymorphism rs1137101 at LEPR gene was analyzed using allelic discrimination assay by Real-Time PCR technique. GG genotype was the most frequent among RCC patients (67.1%), while AA genotype was the most frequent in controls (60%); (p < 0.001). By univariate cox regression: gene polymorphism (GG versus GA +AA), stage, histopathologic subtype, and grade were found to affect survival significantly; however, the multivariate analysis showed that only gene polymorphism (GG versus GA +AA) and tumor stage significantly affect survival. LEPR gene variants rs1137101 might be a candidate risk factor for RCC in Egypt. GG genotype is associated with more aggressive tumor behavior and shorter survival compared with GA & AA genotypes so, genotyping of Gln223Arg (A/G) rs1137101 could also predict RCC outcome. PMID- 29453608 TI - Chemopreventive action of Imatinib, a tyrosine kinase inhibitor in the regulation of angiogenesis and apoptosis in rat model of lung cancer. AB - The present study explored the events of angiogenesis and apoptosis in 7,12 dimethyl benz(a)anthracene (DMBA)-induced lung cancer in rat and its chemoprevention with Imatinib, a receptor tyrosine kinase inhibitor. Further, it includes lipopolysaccharide (LPS) mediating inflammation along with DMBA for the promotion of lung carcinogenesis. The animals received a single intratracheal instillation of DMBA (20 mg/kg body weight) in olive oil and LPS (0.6 mg/kg body weight) to induce tumors in 16 weeks. Besides morphology and histology of the lung tissues, RT-PCR, western blots, and immunofluorescence were performed for the expression of apoptotic and angiogenic proteins. Apoptosis was studied by mitochondrial Bcl-2/Bax ratio and staining with the dyes Acridine orange/ethidium bromide of the isolated Broncho epithelial cells. Also, mitochondrial membrane potential (DeltaPsiM) was studied by JC-1. The study revealed that the expression of VEGF, MMP-2, MMP-9, and the chemokine MCP-1 to be very high in DMBA and DMBA + LPS groups, while Bcl-2 also shows an elevated expression. These results were restored with Imatinib treatment. The pro-apoptotic proteins, Bax, Bad, Apaf-1, and Caspase-3 were highly diminished in DMBA and DMBA + LPS groups which were recovered with Imatinib treatment. PMID- 29453611 TI - Comparative study of phototoxicity of protoporphyrin IX synthetic and extracted from ssp Rattus novergicus albinus rats toward murine melanoma cells. AB - Protoporphyrin IX (PpIX) is a precursor of heme synthesis and is known to be an active photosensitizer and precursor of photosensitizers applied in photodynamic therapy (PDT) and photodynamic diagnostics (PDD). On irradiation with visible light, PpIX undergoes phototransformation, producing photoproducts which may also be phototoxic and increase its efficacy. The mechanism of PpIX phototransformation depends on environmental characteristics and can be different in vitro and in vivo. In this paper, we present a comparative study of the photoactivity of synthetic PpIX and PpIX extracted from the Harderian gland of ssp Rattus novergicus albinus rats, along with their photoproducts toward murine B16F-10 melanoma cells. It was observed that when irradiated with visible light the endogenous PpIX demonstrates photocytotoxicity ten times higher than the synthetic PpIX. The photoproduct of endogenous PpIX also possesses phototoxicity, though slightly lower than that of PpIX itself. The rate of cell internalization for both endogenous PpIX and its photoproduct was eightfold greater than that obtained for the synthetic porphyrin. This difference might result from a complexation of the native PpIX with some amphiphilic compounds during its synthesis within the Harderian glands, which facilitates the cell uptake of PpIX. Fluorescence microscopy images show that both endogenous and synthetic porphyrins are localized after uptake predominantly in the mitochondrial region of cells. PMID- 29453610 TI - Hepatitis C Cure Is Associated with Decreased Healthcare Costs in Cirrhotics in Retrospective Veterans Affairs Cohort. AB - BACKGROUND: Approximately 233,898 individuals in the Veterans Affairs healthcare network are hepatitis C virus (HCV)-infected, making the Veterans Affairs the single largest provider of HCV care in the USA. Direct-acting antiviral treatment regimens for HCV offer high cure rates. However, these medications pose an enormous financial burden, and whether HCV cure is associated with decreased healthcare costs is poorly defined. AIMS: To measure downstream healthcare costs in a national population of HCV-infected patients up to 9 years post-HCV antiviral treatment, to compare downstream healthcare costs between cured and uncured patients, and to assess impact of cirrhosis status on cost differences. METHODS: This is a retrospective cohort study (2004-2014) of hepatitis C-infected patients who initiated antiviral treatment within the United States Veterans Affairs healthcare system October 2004-September 2013. We measured inpatient, outpatient, and pharmacy costs after HCV treatment. RESULTS: For the entire cohort, cure was associated with mean cumulative cost savings in post-treatment years three-six, but no cost savings by post-treatment year nine. By post treatment year nine, cure in cirrhosis patients was associated with a mean cumulative cost savings of $9474 (- 32,666 to 51,614) per patient, while cure in non-cirrhotic patients was associated with a mean cumulative cost excess of $2526 (- 12,211 to 7159) per patient. CONCLUSIONS: Among patients with cirrhosis at baseline, cure is associated with absolute cost savings up to 9 years post treatment compared to those without cure. Among patients without cirrhosis, early post-treatment cost savings are counterbalanced by higher costs in later years. PMID- 29453612 TI - Ancylomarina psychrotolerans sp. nov., isolated from sediments of Fildes Peninsula and emended the description of genus Ancylomarina. AB - A Gram-stain negative, obligately anaerobic, non-motile, asporogenous long rod shaped and non-flagellated bacterial strain, designated 4SWWS2-6T, was isolated from sediment in the intertidal zone of Fildes Peninsula, Antarctica. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain 4SWWS2-6T belongs to the genus Ancylomarina and showed high sequence similarity with Ancylomarina subtilis FA102T (96.5%). Optimal growth occurred at pH 6.5, 16 degrees C and in the presence of 3% (w/v) NaCl. Strain 4SWWS2-6T contained menaquinone-7 (MK-7) as the major respiratory quinone and held iso-C15:0, anteiso C15:0 and iso-C15:0 3-OH as the major cellular fatty acids. The major polar lipids were phosphatidylethanolamine, phosphatidylmonomethylethanolamine, an aminolipid, two unidentified lipids and an unidentified phospholipid. The DNA G + C content of strain 4SWWS2-6T was 37.6 mol%. On the basis of the polyphasic analyses, strain 4SWWS2-6T is considered to represent a novel species in the genus Ancylomarina, for which the name Ancylomarina psychrotolerans sp. nov. is proposed. The type strain is 4SWWS2-6T (= KCTC 15504T = MCCC 1K01618T). PMID- 29453613 TI - In Vitro Antioxidant and Cytotoxic Activities of 18 Plants from the Erkowit Region, Eastern Sudan. AB - We investigated the antioxidant potential and cytotoxicity towards human CCRF-CEM leukemia cells of 57 extracts obtained from 18 plants collected in the Erkowit region, eastern Sudan. The antioxidant activity was determined by measuring the radical scavenging effects against 2,2-diphenyl-1-picrylhydrazyl (DPPH) and N,N dimethyl-p-phenylendiamine (DMPD), metal-chelation capacity, ferric-reducing (FRAP) and phosphomolibdenum-reducing antioxidant power (PRAP) methods using ELISA microtiter assays. Total phenol and flavonoid amounts of the extracts were determined spectrophotometrically. Cytotoxicity towards CCRF-CEM cells was evaluated by the resazurin reduction assay. Geranium favosum followed by Kalanchoe glaucescens, Malva parviflora, Aizoon canariense, and Coleus barbatus, respectively, possessed the highest antioxidant activity among the studied plants. Chrozophora oblongifolia and K. glaucescens exerted considerable cytotoxicity against CCRF-CEM leukemia cells. These plants may serve as source for the further development of natural antioxidant and antitumor agents. PMID- 29453614 TI - Screening of Isochrysis Strains and Utilization of a Two-Stage Outdoor Cultivation Strategy for Algal Biomass and Lipid Production. AB - Isochrysis is a genus of marine algae without cell wall and capable of accumulating lipids. In this study, the lipid production potential of Isochrysis was assessed by comparing 15 Isochrysis strains with respect to their growth rate, lipid production, and fatty acid profiles. Three best strains were selected (lipid productivity, 103.0~121.7 mg L-1 day-1) and their lipid-producing capacities were further examined under different controlled parameters, e.g., growth phase, medium nutrient, and light intensity in laboratory cultures. Furthermore, the three Isochrysis strains were monitored in outdoor panel photobioreactors with various initial cell densities and optical paths, and the strain CS177 demonstrated the superior potential for outdoor cultivation. A two stage semi-continuous strategy for CS177 was subsequently developed, where high productivities of biomass (1.1 g L-1 day-1) and lipid (0.35 g L-1 day-1) were achieved. This is a comprehensive study to evaluate the lipid-producing capability of Isochrysis strains under both indoor and outdoor conditions. Results of the present work lay a solid foundation for the physiological and biochemical responses of Isochrysis to various conditions, shedding light on the future utilization of this cell wall-lacking marine alga for biofuel production. PMID- 29453615 TI - Vidarabine, an anti-herpesvirus agent, prevents catecholamine-induced arrhythmias without adverse effect on heart function in mice. AB - Sympathetic activation causes clinically important arrhythmias including atrial fibrillation (AF) and ventricular tachyarrhythmia. Although the usefulness of beta-adrenergic receptor blockade therapy is widely accepted, its multiple critical side effects often prevent its initiation or continuation. The aim of this study is to determine the advantages of vidarabine, an adenylyl cyclase (AC) targeted anti-sympathetic agent, as an alternative treatment for arrhythmia. We found that vidarabine, which we identified as a cardiac AC inhibitor, consistently shortens AF duration and reduces the incidence of sympathetic activation-induced ventricular arrhythmias. In atrial and ventricular myocytes, vidarabine inhibits adrenergic receptor stimulation-induced RyR2 phosphorylation, sarcoplasmic reticulum (SR) Ca2+ leakage, and spontaneous Ca2+ release from SR, the last of which has been considered as a potential arrhythmogenic trigger. Moreover, vidarabine also inhibits sympathetic activation-induced reactive oxygen species (ROS) production in cardiac myocytes. The pivotal role of vidarabine's inhibitory effect on ROS production with regard to its anti-arrhythmic property has also been implied in animal studies. In addition, as expected, vidarabine exerts an inhibitory effect on AC function, which is more potent in the heart than elsewhere. Indexes of cardiac function including ejection fraction and heart rate were not affected by a dosage of vidarabine sufficient to exert an anti arrhythmic effect. These findings suggest that vidarabine inhibits catecholamine induced AF or ventricular arrhythmia without deteriorating cardiac function in mice. PMID- 29453617 TI - Site suitability evaluation of an old operating landfill using AHP and GIS techniques and integrated hydrogeological and geophysical surveys. AB - Because of the outdated methods of common landfill selection, it is imperative to reevaluate the usage suitability. To assess the suitability of the existing waste landfill in Zanjan, Iran, we have used a combination of the analytical hierarchy process (AHP) and GIS techniques, along with fieldwork surveys. Four major criteria and 12 subcriteria were considered, and the AHP was applied to assign the relative importance weights of criteria and subcriteria to each other. Finally, a landfill suitability map was generated and ranked based on the final suitability scores. The results show that the unsuitable areas are around Zanjan, in the middle parts of the plain. By contrast, the most suitable areas are uncultivated areas, located mostly in the west, north, and south. The results also indicate that the present landfill is a highly suitable site. After desk studies, geoelectrical surveys and infiltration measurements were conducted to make the final decision. Double-ring permeability tests confirm the landfill is an acceptable site. The electrical sounding shows that the leachate plume has a width of about ~ 450 m, spreads to a depth of about ~ 55 m, and migrates towards the northeast. Considering the groundwater depth, dry climate, and a low infiltration rate of the landfill soils, it can be concluded that leachate plumes will not contaminate groundwater within this decade. The proposed method can be implemented to reevaluate the suitability of any old operating reservoir such as oil reservoirs, petrol filling stations, heavy industrial tanks, and landfills, containing liquid hazardous materials. PMID- 29453616 TI - Laser-induced plasma spectroscopy (LIPS): use of a geological tool in assessing bone mineral content. AB - Bone may be similar to geological formulations in many ways. Therefore, it may be logical to apply laser-based geological techniques in bone research. The mineral and element oxide composition of bioapatite can be estimated by mathematical models. Laser-induced plasma spectrometry (LIPS) has long been used in geology. This method may provide a possibility to determine the composition and concentration of element oxides forming the inorganic part of bones. In this study, we wished to standardize the LIPS technique and use mathematical calculations and models in order to determine CaO distribution and bone homogeneity using bovine shin bone samples. We used polished slices of five bovine shin bones. A portable LIPS instrument using high-power Nd++YAG laser pulses has been developed (OpLab, Budapest). Analysis of CaO distribution was carried out in a 10 * 10 sampling matrix applying 300-MUm sampling intervals. We assessed both cortical and trabecular bone areas. Regions of interest (ROI) were determined under microscope. CaO peaks were identified in the 200-500 nm wavelength range. A mathematical formula was used to calculate the element oxide composition (wt%) of inorganic bone. We also applied two accepted mathematical approaches, the Bartlett's test and frequency distribution curve-based analysis, to determine the homogeneity of CaO distribution in bones. We were able to standardize the LIPS technique for bone research. CaO concentrations in the cortical and trabecular regions of B1-5 bones were 33.11 +/- 3.99% (range 24.02 40.43%) and 27.60 +/- 7.44% (range 3.58-39.51%), respectively. CaO concentrations highly corresponded to those routinely determined by ICP-OES. We were able to graphically demonstrate CaO distribution in both 2D and 3D. We also determined possible interrelations between laser-induced craters and bone structure units, which may reflect the bone structure and may influence the heterogeneity of CaO distributions. By using two different statistical methods, we could confirm if bone samples were homogeneous or not with respect to CaO concentration distribution. LIPS, a technique previously used in geology, may be included in bone research. Assessment of element oxide concentrations in the inorganic part of bone, as well as mathematical calculations may be useful to determine the content of CaO and other element oxides in bone, further analyze bone structure and homogeneity and possibly apply this research to normal, as well as diseased bones. PMID- 29453618 TI - Lumbosacral transitional vertebrae: significance of local bone marrow edema at the transverse processes. AB - OBJECTIVE: To evaluate the association between low back pain and bone marrow edema in lumbosacral transitional vertebra (LSTV) transverse processes, and to assess the prevalence of LSTV in a physically active population. MATERIALS AND METHODS: Individuals with LSTV on coronal MRI studies were identified in a retrospective review by keyword search from PACS. In total, 140 cases were reviewed by two fellowship-trained musculoskeletal radiologists. Data on associated low back pain were collected from patient records at the time of the imaging. RESULTS: Bone marrow edema was observed in 44% of the cases, but no correlation with low back pain was found. On coronal MRI, the prevalence of LSTV was 2.6%, with type II LSTV being the most common subtype. CONCLUSIONS: No correlation with bone marrow edema at the transverse processes of the LSTV and low back pain was observed. In our selected study population, the prevalence of LSTV was low. PMID- 29453619 TI - An Electronic Medical Record Alert Intervention to Improve HPV Vaccination Among Eligible Male College Students at a University Student Health Center. AB - This pilot study aims to improve HPV vaccination for college aged males at a student health center. The first part of the study consisted of a focus group that assessed the barriers and facilitators of HPV vaccination among healthcare providers and clinic staff (N = 16). Providers reported missed opportunities for HPV vaccination. For the second part of the study, providers and staff reviewed medical records of patients ages 18-26 with student health insurance and with < 3 doses of the HPV vaccine at baseline (12/1/2014 to 7/31/2015) and follow-up (12/1/2015 to 7/31/2016). A computer-automated EMR alert was generated in the medical record of eligible male patients (N = 386). Z-scores were estimated for two-sample proportions to measure change in HPV vaccine rates at baseline and follow-up for males and females. HPV vaccine initiation rates increased among males (baseline: 5.2% follow-up: 25.1%, p < 0.001). This study shows that EMR alerts improved HPV vaccine initiation rates among insured college-aged males. PMID- 29453621 TI - Response preparation, response selection difficulty, and response-outcome learning. AB - Voluntary action control is accomplished through anticipating that action's perceptual outcomes. Some evidence suggests that this is only true when responses are intention-based rather than stimulus-based and that this difference is evidence of different response modes. More recently, however, it has been shown that response-outcome retrieval effects can occur with stimulus-based responses, and that the retrieval depended on response selection efficiency as decreasing the response selection efficiency increased response-outcome retrieval (Gozli et al., J Exp Psychol: Hum Percept Perform, 2016). We look to extend this finding by manipulating response selection difficulty within (Experiment 1) or between blocks (Experiment 2) and response preparation time (Experiment 1) within an experiment. Individuals completed a task in which they responded to onsets using the spatially corresponding finger. The onset was preceded by precues narrowing down the response possibilities from four to two. The response possibilities were either on the same hand or different hands, such that response selection was easy or hard. We also varied the amount of time between the cues and the targets to manipulate response preparation time. The results indicated that trial-by-trial manipulations of response selection difficulty did not influence response-outcome retrieval, but that the between groups manipulation of response preparation time did. With less time response preparation time, larger response-outcome compatibility effects were found. This study presents further evidence that response selection efficiency can influence response-outcome retrieval and that this difference can be accounted for in terms of how prepared the responses are at the time of target presentation. PMID- 29453620 TI - Long-term hearing results of stapedotomy: analysis of factors affecting outcome. AB - OBJECTIVE: To evaluate long-term hearing results of stapedotomy and analyze the influence of patient-, disease-, and procedure-related variables. STUDY DESIGN: Retrospective case series. SETTING: Tertiary referral center. PATIENTS: 230 ears (202 patients, 10-74 years) underwent stapedotomy for otosclerosis between January 2008 and August 2014. All cases had early postoperative follow-up (4 weeks post-surgery) and 181 cases had late postoperative follow-up (>= 1 year, average 32.5 months). INTERVENTION: Stapedotomy procedure for otosclerosis. MAIN OUTCOME MEASURES: Hearing outcome using conventional audiometry. The primary outcome parameter was the postoperative air-bone gap pure-tone average. Postoperative air-bone gap <= 10 dB was defined as surgical success. Preoperative, early postoperative and late postoperative hearing results were compared. Influence of patient- and procedure-related variables on hearing outcome was evaluated by logistic regression analysis. RESULTS: The postoperative air-bone gap was 10 dB or less in 77.0% of cases early post-surgery and in 70.7% of cases in long-term follow-up. Air-bone gap closure within 20 dB was obtained in 95.7 and 92.3%, respectively. Logistic regression analysis demonstrated that a larger preoperative air-bone gap (p = 0.041) and positive family history of otosclerosis (p = 0.044) were predictive for less surgical success early postoperatively, but not on the long term. Age, gender, primary versus revision surgery, presence of preoperative tinnitus and preoperative vertigo did not independently and significantly influence postoperative air-bone gap closure. CONCLUSION: Our series confirms excellent hearing results achieved in stapedotomy surgery, also in long-term follow-up. On the long-term no patient-, disease-, or procedure-related variables were identified as predictors of surgical success. PMID- 29453622 TI - Cognitive Mediators of Change in Physical Functioning in Response to a Multifaceted Intervention for Managing Osteoarthritis. AB - PURPOSE: Although non-pharmacological interventions have been shown to improve physical functioning in individuals with osteoarthritis (OA), the mechanisms by which this occurs are often unclear. This study assessed whether changes in arthritis self-efficacy, perceived pain control, and pain catastrophizing mediated changes in physical functioning following an osteoarthritis intervention involving weight management, physical activity, and cognitive-behavioral pain management. METHOD: Three hundred Veteran patients of 30 primary care providers with knee and/or hip OA were cluster randomized to an OA intervention group or usual care. The OA intervention included a 12-month phone-based patient behavioral protocol (weight management, physical activity, and cognitive behavioral pain management) plus patient-specific OA treatment recommendations delivered to primary care providers. RESULTS: Using linear mixed models adjusted for provider clustering, we observed that baseline to 6-month changes in arthritis self-efficacy and pain control partially mediated baseline to 12-month physical functioning improvements for the intervention group; catastrophizing did not. CONCLUSION: Findings of a mediating role of arthritis self-efficacy and pain control in intervention-related functional changes are consistent with hypotheses and align with theoretical assertions of the role of cognitions in cognitive and behavioral interventions for chronic pain. However, contrary to hypotheses, catastrophizing was not found to be a mediator of these changes. PMID- 29453623 TI - A novel suction/coagulation integrated probe for achieving better hemostasis: development and clinical use. AB - PURPOSES: Modern electrosurgical tools have a specific coagulation mode called "soft coagulation". However, soft coagulation has not been widely accepted for surgical operations. To optimize the soft coagulation environment, we developed a novel suction device integrated with an electrosurgical probe, called the "Suction ball coagulator" (SBC). In this study, we aimed to optimize the SBC design with a prototyping process involving a bench test and preclinical study; then, we aimed to demonstrate the feasibility, safety, and potential effectiveness of the SBC for laparoscopic surgery in clinical settings. METHODS: SBC prototyping was performed with a bench test. Device optimization was performed in a preclinical study with a domestic swine bleeding model. Then, SBC was tested in a clinical setting during 17 clinical laparoscopic colorectal surgeries. RESULTS: In the bench tests, two tip hole sizes and patterns showed a good suction capacity. The preclinical study indicated the best tip shape for accuracy. In clinical use, no device-related adverse event was observed. Moreover, the SBC was feasible for prompt hemostasis and blunt dissections. In addition, SBC could evacuate vapors generated by tissue ablation using electroprobe during laparoscopic surgery. CONCLUSIONS: We successfully developed a novel, integrated suction/coagulation probe for hemostasis and commercialized it. PMID- 29453624 TI - Hydroxyurea responses in clinically varied beta, HbE-beta thalassaemia and sickle cell anaemia patients of Eastern India. AB - The haematological and clinical response to hydroxyurea was estimated in HbE beta, beta thalassaemia and sickle cell anaemia patients of Eastern India, with variable clinical severity and transfusion requirement to determine whether hydroxyurea can help these patients to maintain their steady haemoglobin level without blood transfusions. Three hundred patients (189 HbE-beta thalassaemia, 95 beta thalassaemia and 16 other haemoglobinopathies including sickle cell anaemia) were selected for hydroxyurea therapy and were followed up for 48-60 months. Results suggest significant response to hydroxyurea therapy in 19 beta and 99 HbE beta patients in the transfusion-dependent group (GR-I). All of them became transfusion-independent while on hydroxyurea therapy. The majority of responding patients were IVS1-5(G-C) in one of their alleles in HbE-beta cases (83 out of 119). Though IVS1-5(G-C) was found to be the commonest mutation in our selected patients, the mutational background of the patients does not found to have any significant correlation with the response category towards hydroxyurea as per the results observed in our study. But, the drug works pretty well in most of the transfusion-dependent patients, as these patients were withdrawn from regular blood transfusion. At the same time, partial or no response to the drug hydroxyurea was also recorded in our study. PMID- 29453625 TI - Effects of feedstock and co-culture of Lactobacillus fermentum and wild Saccharomyces cerevisiae strain during fuel ethanol fermentation by the industrial yeast strain PE-2. AB - Even though contamination by bacteria and wild yeasts are frequently observed during fuel ethanol fermentation, our knowledge regarding the effects of both contaminants together is very limited, especially considering that the must composition can vary from exclusively sugarcane juice to a mixture of molasses and juice, affecting the microbial development. Here we studied the effects of the feedstock (sugarcane juice and molasses) and the co-culture of Lactobacillus fermentum and a wild Saccharomyces cerevisiae strain (rough colony and pseudohyphae) in single and multiple-batch fermentation trials with an industrial strain of S. cerevisiae (PE-2) as starter yeast. The results indicate that in multiple-cycle batch system, the feedstock had a minor impact on the fermentation than in single-cycle batch system, however the rough yeast contamination was more harmful than the bacterial contamination in multiple-cycle batch fermentation. The inoculation of both contaminants did not potentiate the detrimental effect in any substrate. The residual sugar concentration in the fermented broth had a higher concentration of fructose than glucose for all fermentations, but in the presence of the rough yeast, the discrepancy between fructose and glucose concentrations were markedly higher, especially in molasses. The biggest problem associated with incomplete fermentation seemed to be the lower consumption rate of sugar and the reduced fructose preference of the rough yeast rather than the lower invertase activity. Lower ethanol production, acetate production and higher residual sugar concentration are characteristics strongly associated with the rough yeast strain and they were not potentiated with the inoculation of L. fermentum. PMID- 29453626 TI - Drug approval based on randomized phase 3 trials for relapsed malignancy: analysis of oncologic drugs granted accelerated approval, publications and clinical trial databases. AB - Background As relapsed disease is frequently the first target of newly developed therapies, it is vital to address the difficulty in demonstrating the efficacy of new drugs for relapsed malignancy in randomized phase 3 trials. Methods We analyzed the approved indications, target populations, and development status of post-marketing confirmatory trials of all oncology-related drugs that were granted accelerated approval for both hematological and solid malignancies. Furthermore, we searched for randomized phase 3 trials for adult patients with relapsed lymphoid malignancy, other than chronic lymphocytic leukemia (CLL) and multiple myeloma (MM). Results Thirty-one (81.6%) of the 38 hematological indications and 23 (53.5%) of the 43 solid malignancy indications were in the relapsed settings. The target population of post-marketing studies was different from the approved indication in 18 (47.4%) of 38 hematological indications and 11 (25.6%) of 43 solid malignancy indications; all 18 hematological indications involved relapsed settings. Improved time-to-event outcome for relapsed patients was the primary endpoint in 6 (19.3%) of the 31 relapsed hematological indications. In 4 published studies of relapsed lymphoid malignancy, the medication significantly improved outcomes. From 33 trials listed at Clinicaltrials.gov , 2 were positive and 13 were negative. Five out of the 13 negative trials were terminated due to poor accrual. Conclusion Our analysis indicates that drug approval based on phase 3 trials is more challenging for relapsed hematological malignancies than for solid malignancies. Therefore, determining proper evaluation methods for the efficacy and safety of drugs for relapsed malignancy, without randomized trials, is important. PMID- 29453627 TI - A phase I and pharmacokinetic study of taladegib, a Smoothened inhibitor, in Japanese patients with advanced solid tumors. AB - Background This phase I dose-escalation study investigated the safety of the Smoothened inhibitor taladegib in Japanese patients with advanced solid tumors. Methods Patients received taladegib orally once daily for 28-day cycles, using a 3 + 3 dose-escalation method. The primary objective was the safety and tolerability of taladegib at doses up to the global recommended dose (400 mg). Secondary objectives included pharmacokinetics, changes in skin glioma-associated oncogene homolog 1 (Gli1) transcript levels, and antitumor activity. Results Nineteen patients received treatment (100 mg: 3; 200 mg: 3; 400 mg: 13). No dose limiting toxicities (DLTs) were observed at doses of 100 mg or 200 mg; 3 of the 9 patients evaluable for DLTs at the 400 mg dose level experienced DLTs (thrombocytopenia: 1; decreased appetite: 2). The most commonly reported treatment-related adverse events were dysgeusia (13/19, 68.4%), decreased appetite (12/19, 63.2%), nausea (9/19, 47.4%), fatigue (9/19, 47.4%), and vomiting (6/19, 31.6%). The pharmacokinetic profile suggested that exposure to taladegib was higher in Japanese than non-Japanese patients, possibly related to differences in body weight and/or drug formulation. At all dose levels, a high level of inhibition of skin Gli1 transcript levels was observed after 15 and 30 days of exposure to taladegib. Partial response was achieved by 1 patient (basal cell carcinoma of the skin) and stable disease by 4 patients. Conclusions Taladegib doses of 100 mg and 200 mg, but not the global recommended dose of 400 mg, were well tolerated in this population of Japanese patients with advanced solid tumors. PMID- 29453628 TI - Safety, tolerability, and preliminary activity of IMGN529, a CD37-targeted antibody-drug conjugate, in patients with relapsed or refractory B-cell non Hodgkin lymphoma: a dose-escalation, phase I study. AB - Background CD37 is expressed on B-cell lymphoid malignancies, thus making it an attractive candidate for targeted therapy in non-Hodgkin lymphoma (NHL). IMGN529 is an antibody-drug conjugate comprising a CD37-binding antibody linked to the maytansinoid DM1, a potent anti-mitotic agent. Methods This first-in-human, phase 1 trial recruited adult patients with relapsed or refractory B-cell NHL. The primary objective was to determine the maximum tolerated dose (MTD) and recommended phase 2 dose. Secondary objectives were to evaluate safety, pharmacokinetics, and preliminary clinical activity. IMGN529 was administered intravenously once every 3 weeks, and dosed using a conventional 3 + 3 dose escalation design. Results Forty-nine patients were treated at doses escalating from 0.1 to 1.8 mg/kg. Dose limiting toxicities occurred in eight patients and included peripheral neuropathy, febrile neutropenia, neutropenia, and thrombocytopenia. The most frequent treatment-emergent adverse events were fatigue (39%), neutropenia, pyrexia, and thrombocytopenia (each 37%). Adverse events led to treatment discontinuation in 10 patients (20%). Eight patients (16%) had treatment-related serious adverse events, the most common being grade 3 febrile neutropenia. The MTD (with growth factor support) was 1.4 mg/kg every 3 weeks. IMGN529 plasma exposure increased monotonically with dose and was consistent with target-mediated drug disposition. Five (13%) of 39 response evaluable patients achieved an objective response (one complete response and four partial responses), four of which occurred in the subgroup of patients with diffuse large B-cell lymphoma. Conclusions The manageable safety profile of IMGN529 and preliminary evidence of activity, particularly in DLBCL patients, support the continued development of this novel CD37-targeting agent.

Because pharmacological effects and special complications are possible, monitoring and precautions are mandatory. PMID- 29453630 TI - Somatic BRCA1 mutations in clinically sporadic breast cancer with medullary histological features. AB - BACKGROUND: The role of somatic BRCA1/2 gene mutations in breast cancer is getting increasing attention in view of hereditary disease. The medullary phenotype and triple negative intrinsic subtypes are often, but not exclusively encountered in BRCA1 germline mutated breast cancer, whilst for BRCA2, no association to specific histological features are known. In this study, we addressed the relationship between morphological medullary phenotype and BRCA1/2 somatic mutations in breast cancer without known positive family anamnesis. METHODS: 32 clinically sporadic breast cancers with medullary features were analyzed for somatic BRCA1/2 mutations (all coding exons) with next-generation sequencing technology. Paraffin-embedded formalin-fixed breast cancer samples from all patients were analyzed. RESULTS: Three of 32 tumors (9%) had pathogenic (ARUP class-5) BRCA1 gene alterations. Two of these pathogenic variants exhibited deletions leading to frameshift mutations (p.Glu23fs, p.Val1234fs), and the remaining single-nucleotid-variant resulted in premature STOP codon (p.Glu60Ter). In one patient, the same pathogenic BRCA1 mutation was detected (p.Glu23fs) in normal breast tissue. Retrospective follow-up in two patients revealed a positive family history for breast cancer and consecutive germline mutation testing confirmed presence of BRCA1 mutations. No somatic pathogenic BRCA2 mutations were detected. CONCLUSIONS: BRCA1 mutation testing may be useful in clinically sporadic breast cancer patients with medullary features to identify potential mutation carriers independently from intrinsic molecular subtype. Formalin-fixed paraffin-embedded cancer tissue can undergo testing within a routine molecular diagnostic setting as a clinical BRCA1/2 mutation screening strategy. PMID- 29453631 TI - Occupational Animal Allergy. AB - PURPOSE OF REVIEW: This review explores animal allergen exposure in research laboratories and other work settings, focusing on causes and prevention. RECENT FINDINGS: (1) Consistent with the hygiene hypothesis, there is new evidence that early childhood exposure to pets produces changes in the gut microbiome that likely lead to a lower risk of allergy. (2) Anaphylaxis from laboratory animal bites occurs more frequently than suggested by prior literature. (3) Animal allergens represent an occupational hazard in a wide variety of work settings ranging from fields that work with animals to public settings like schools and public transportation where allergens are brought into or are present in the workplace. Exposure to animal allergens can result in allergy, asthma, and anaphylaxis. Animal allergy has been most studied in the research laboratory setting, where exposure reduction can prevent the development of allergy. Similar prevention approaches need to be considered for other animal work environments and in all settings where animal allergens are present.

AB - Development of alternatives to antibiotic growth promoters (AGP) used in swine production requires a better understanding of their impacts on the gut microbiota. Supplementing fermented feed (FF) in swine diets as a novel nutritional strategy to reduce the use of AGP and feed price, can positively affect the porcine gut microbiota, thereby improving pig productivities. Previous studies have noted the potential effects of FF on the shift in benefit of the swine microbiota in different regions of the gastrointestinal tract (GIT). The positive influences of FF on swine gut microbiota may be due to the beneficial effects of both pre- and probiotics. Necessarily, some methods should be adopted to properly ferment and evaluate the feed and avoid undesired problems. In this mini-review, we mainly discuss the microbiota in both fermented feed and swine gut and how FF influences swine gut microbiota.

AB - Fungi of the genus Colletotrichum are economically important and are used as models in plant-pathogen interaction studies. In this study, the complete mitochondrial genomes of two Colletotrichum lindemuthianum isolates were sequenced and compared with the mitochondrial genomes of seven species of Colletotrichum. The mitochondrial genome of C. lindemuthianum is a typical circular molecule 37,446 bp (isolate 89 A2 2-3) and 37,440 bp (isolate 83.501) in length. The difference of six nucleotides between the two genomes is the result of a deletion in the ribosomal protein S3 (rps3) gene in the 83.501 isolate. In addition, substitution of adenine for guanine within the rps3 gene in the mitochondrial genome of the 83.501 isolate was observed. Compared to the previously sequenced C. lindemuthianum mitochondrial genome, an exon no annotated in the cytochrome c oxidase I (cox1) gene and a non-conserved open reading frame (ncORF) were observed. The size of the mitochondrial genomes of the seven species of Colletotrichum was highly variable, being attributed mainly to the ncORF, ranging from one to 10 and also from introns ranging from one to 11 and which encode a total of up to nine homing endonucleases. This paper reports for the first time by means of transcriptome that then ncORFs are transcribed in Colletotrichum spp. Phylogeny data revealed that core mitochondrial genes could be used as an alternative in phylogenetic relationship studies in Colletotrichum spp. This work contributes to the genetic and biological knowledge of Colletotrichum spp., which is of great economic and scientific importance. PMID- 29453634 TI - Comparison of serological and molecular typing methods for epidemiological investigation of Tenacibaculum species pathogenic for fish. AB - In the present study, the potential of serological methods, the repetitive extragenic palindromic PCR (REP-PCR) and the enterobacterial repetitive intergenic consensus sequence PCR (ERIC-PCR) for the typing of the species Tenacibaculum maritimum, Tenacibaculum soleae and Tenacibaculum discolor was evaluated. Moreover, molecular and proteomic techniques were used to assess variability among strains belonging to different serotypes, as well as isolated from different host species and geographical areas. Slide agglutination and dot blot assays demonstrated the lack of immunological relationships among Tenacibaculum species analyzed. The serotype O1 was predominant within T. maritimum isolates regardless of the fish species or geographical area. Two serotypes were distinguished within T. soleae isolates and at least one within T. discolor strains. Species- and strain-specific profiles were obtained from the analysis of T. maritimum, T. soleae and T. discolor by REP-PCR and ERIC-PCR, demonstrating their potential as diagnostic tools. The genotyping analysis using both techniques showed genetic variability among the strains of each fish pathogenic Tenacibaculum species analysed. However, Tenacibaculum strains isolated from different host species or geographical areas or belonging to different serotypes produced REP and ERIC profiles with high similarity. Analysis by MALDI-TOF-MS of the T. maritimum strains could not detect any serotype identifying biomarkers. Serotype-specific mass peaks were found for the serotypes O1 and O2 of T. soleae and for the serotype O1 of T. discolor. However, no relationships between the proteomic profiles and the source of isolation of the strains were obtained for any of the Tenacibaculum species analysed in this study. PMID- 29453637 TI - Cough hypersensitivity in patients with obstructive sleep apnea hypopnea syndrome. AB - PURPOSE: The purpose of this study was to investigate cough hypersensitivity and its potential mechanisms in patients with obstructive sleep apnea hypopnea syndrome (OSAHS). METHODS: Fifteen OSAHS patients, 12 simple snoring patients, and 15 healthy volunteers received cough sensitivity test and induced sputum cytology. Cough thresholds C2 and C5 (the minimum of capsaicin inducing >= 2 and >= 5 coughs, respectively), total cell count, cell differentials and the levels of bradykinin, histamine, prostaglandin E2, substance P, calcitonin gene-related peptide, pepsin, and interleukin-2 in the induced sputum detected by enzyme linked immunosorbent assay were compared. The linear correlation between lgC2 and lgC5 and apnea hypopnea index, cell differentials, and inflammatory mediators in the induced sputum was calculated in OSAHS patients. RESULTS: OSAHS patients presented with a significant lower C2 and C5 (P < 0.01), increased lymphocyte but decreased macrophage and neutrophil proportions in the induced sputum (P < 0.01), and higher contents of substance P, calcitonin gene-related peptide and interleukin-2 (P < 0.01) but similar levels of bradykinin, pepsin, prostaglandin E2, and histamine (P > 0.05) in the supernatant of induced sputum, when compared with simple snoring patients and healthy volunteers. However, theses variable were comparable between simple snoring patients and healthy volunteers (P > 0.05). Finally, lgC2 or lgC5 was negatively related to apnea hypopnea index, lymphocyte percentage, and the levels of substance P, calcitonin gene-related peptide or interleukin-2 in the sputum (P < 0.01). There was a positive linear correlation between lymphocyte percentage and interleukin-2 level in the induced sputum (r = 0.63, P = 0.00). CONCLUSION: OSAHS patients have a predisposition of cough hypersensitivity associated with airway inflammation. PMID- 29453636 TI - Assessment of oximetry-based statistical classifiers as simplified screening tools in the management of childhood obstructive sleep apnea. AB - PURPOSE: A variety of statistical models based on overnight oximetry has been proposed to simplify the detection of children with suspected obstructive sleep apnea syndrome (OSAS). Despite the usefulness reported, additional thorough comparative analyses are required. This study was aimed at assessing common binary classification models from oximetry for the detection of childhood OSAS. METHODS: Overnight oximetry recordings from 176 children referred for clinical suspicion of OSAS were acquired during in-lab polysomnography. Several training and test datasets were randomly composed by means of bootstrapping for model optimization and independent validation. For every child, blood oxygen saturation (SpO2) was parameterized by means of 17 features. Fast correlation-based filter (FCBF) was applied to search for the optimum features. The discriminatory power of three statistical pattern recognition algorithms was assessed: linear discriminant analysis (LDA), quadratic discriminant analysis (QDA), and logistic regression (LR). The performance of each automated model was evaluated for the three common diagnostic polysomnographic cutoffs in pediatric OSAS: 1, 3, and 5 events/h. RESULTS: Best screening performances emerged using the 1 event/h cutoff for mild-to-severe childhood OSAS. LR achieved 84.3% accuracy (95% CI 76.8-91.5%) and 0.89 AUC (95% CI 0.83-0.94), while QDA reached 96.5% PPV (95% CI 90.3-100%) and 0.91 AUC (95% CI 0.85-0.96%). Moreover, LR and QDA reached diagnostic accuracies of 82.7% (95% CI 75.0-89.6%) and 82.1% (95% CI 73.8-89.5%) for a cutoff of 5 events/h, respectively. CONCLUSIONS: Automated analysis of overnight oximetry may be used to develop reliable as well as accurate screening tools for childhood OSAS. PMID- 29453635 TI - Monitoring of erlotinib in pancreatic cancer patients during long-time administration and comparison to a physiologically based pharmacokinetic model. AB - PURPOSE: In this study, a therapeutic drug monitoring (TDM) of erlotinib in pancreatic cancer patients was performed over 50 weeks to reveal possible alterations in erlotinib plasma concentrations. Additionally, a physiologically based pharmacokinetic (PBPK) model was created to assess such variations in silico. METHODS: Patients with advanced pancreatic cancer received a chemotherapeutic combination of 100 mg erlotinib q.d., 500-900 mg capecitabine b.d. and 5 mg/kg bevacizumab q.2wks. Samples were analyzed by HPLC and the results were compared to a PBPK model, built with the software GastroPlusTM and based on calculated and literature data. RESULTS: The erlotinib plasma concentrations did not show any accumulation, but displayed a high inter-patient variability over the whole investigated period. Trough plasma concentrations ranged from 0.04 to 1.22 ug/ml after day 1 and from 0.01 to 2.4 ug/ml in the long term assessment. 7% of the patients showed concentrations below the necessary activity threshold of 0.5 ug/ml during the first week. The impact of some co variates on the pharmacokinetic parameters Cmax and AUC0-24 were shown in a PBPK model, including food effects, changes in body weight, protein binding or liver function and the concomitant intake of gastric acid reducing agents (ARAs). CONCLUSION: This study presents the approach of combining TDM and PBPK modeling for erlotinib, a drug with a high interaction potential. TDM is an important method to monitor drugs with increased inter-patient variability, additionally, the PBPK model contributed valuable insights to the interaction mechanisms involved, resulting in an effective combination from a PK perspective to ensure a safe treatment. PMID- 29453638 TI - Effects of CPAP therapy on cognitive and psychomotor performances in patients with severe obstructive sleep apnea: a prospective 1-year study. AB - STUDY OBJECTIVES: We prospectively investigated the effects of continuous positive airway pressure (CPAP) on long-term cognitive and psychomotor performances, and excessive daytime sleepiness in severe obstructive sleep apnea (OSA) patients. METHODS: A total of 40 patients were recruited and 23 patients with severe OSA fully completed the study protocol to investigate the effects of CPAP therapy on psychomotor performance at 1, 3, and 6 months and 1 year following initiation of the therapy. Psychomotor CRD-series tests measuring reaction times of light stimulus perception, solving simple arithmetic operations, and complex psychomotor limb coordination, were used in this study. The data collected following CPAP therapy were compared to baseline values prior to the CPAP treatment for each patient. RESULTS: All of the measured variables improved following CPAP treatment. However, the most pronounced effect was observed in improvement of reaction times to complex psychomotor limb coordination test (p < 0.05). Self-reported evaluation of excessive daytime sleepiness measured by Epworth Sleepiness Scale (ESS) showed significant decrease from 10.0 +/- 1.1 before to 3.5 +/- 0.5 (p < 0.001), after 1 year on CPAP therapy. CONCLUSIONS: The CPAP therapy improved cognitive and psychomotor performance on CRD-series tests with the most significant improvement observed in complex psychomotor limb coordination of severe OSA patients. PMID- 29453639 TI - Upper airway obstruction induced by non-invasive ventilation using an oronasal interface. AB - BACKGROUND: On initiation of long-term non-invasive ventilation (NIV), intermittent upper airway obstruction has rarely been described as possibly treatment-induced. Inspiratory pressure effects and the use of an oronasal interface may promote obstructive events in some patients with neuromuscular disease (NMD) and amyotrophic lateral sclerosis (ALS) in particular. METHODS: We evaluated clinical data from 212 patients in whom NIV was initiated using an oronasal mask. Treatment-induced upper airway obstruction (TAO) was defined as an AHI > 5/h along with a relative increase of the AHI in the first treatment night compared to diagnostic sleep studies. RESULTS: Prevalence of TAO was 14.2% in the entire cohort, 17.0% in patients with NMD (n = 165), 20.4% in the ALS subgroup (n = 93), and 4.3% in non-NMD patients (n = 47). Fixed expiratory positive airway pressure (EPAP, n = 192) was significantly correlated with AHI reduction (r = 0.50; p < 0.001). The inspiratory-expiratory pressure interval (?PAP, n = 191) showed inverse correlation with the AHI change achieved in the first treatment night (r = - 0.28; p < 0.001). However, ?PAP and the effective pressure range between EPAP and the highest inspiratory PAP achieved were not predictive of TAO. In patients with ALS, TAO was associated with better bulbar function. Study results were limited by initial EPAP being significantly lower in NMD patients reflecting that sleep apnea was less frequent and severe in this subgroup. CONCLUSIONS: Initiation of NIV using an oronasal interface may be associated with TAO in a subset of patients. Since both EPAP and ?PAP appear to play a causative role, careful titration of ventilator settings is recommended. PMID- 29453640 TI - Effect of semi-rapid maxillary expansion in children with obstructive sleep apnea syndrome: 5-month follow-up study. AB - BACKGROUND: The purpose of this study was to investigate the effect of semi-rapid maxillary expansion (SRME) orthodontic treatment on biomarkers and respiratory parameters in children with obstructive sleep apnea syndrome (OSAS) and maxillary transverse deficiency. METHODS: Thirty children with OSAS were included in this study. Fifteen children were enrolled as control, and 15 children were subjected to SRME orthodontic treatment method for 5 months. Beside respiratory parameters, pharyngeal area, dental arch, and postero-anterior widths and the levels of OSAS biomarkers in serum and urine were measured. RESULTS: Pharyngeal airway space, dental arch, and postero-anterior widths were increased after SRME treatment. Sleep tests showed a decrease in the apnea-hypopnea index (AHI) after 5-month control/treatment duration. Serum kallikrein (KLK)1 levels decreased significantly in the treatment group. There was a significant increase in serum orosomucoid (ORM)2 levels and a decrease in urine perlecan levels in the control group after a 5-month follow-up. A significant negative correlation between serum ORM2, perlecan, gelsolin, and KLK1 levels and intercanin width, as well as between serum ORM2 and KLK1 levels and intermolar width, was observed. CONCLUSIONS: SRME treatment can be considered as a useful approach in children with OSAS. A further investigation of OSAS-related biomarkers and their relationship with sleep and orthodontic parameters is needed for providing easier and reliable modulatory strategies in the treatment of OSAS. PMID- 29453641 TI - Factor Structure and Psychometric Properties of the Thoughts About Psychotherapy Survey in a Parent Sample. AB - Researchers have noted that treatment fearfulness (e.g., embarrassment or negative attitudes) causes individuals to avoid seeking therapy. The purpose of this study was to examine the psychometric properties of the Thoughts About Psychotherapy Survey (TAPS; Kushner and Sher in Prof Psychol Res Prac 20(4):251 257, 1989) in a sample of parents. This study also examined differences in therapy fears among parents with and without a history of using mental health services. Using a sample of 138 parents (87% female), findings indicated that a three factor structure of the TAPS was a good fit for the data. Furthermore, the scales demonstrated "good" internal consistency ranging from .86 to .93. Finally, parents that reported previous use of mental health services reported fewer treatment fears. Given these findings, the TAPS appears to be a valid measure to assess treatment fears among parents. Implications for research and practice will be discussed. PMID- 29453642 TI - Repeated closed reduction attempts of distal radius fractures in the emergency department. AB - INTRODUCTION: Repeated attempts of closed reduction of distal radius fractures (DRF) are performed in the emergency department setting to optimize fracture alignment and avoid surgery. The additional manipulation of the fracture may, however, increase dorsal comminution and lead to loss of reduction in the cast. This retrospective cohort study has investigated the effect of second reduction attempt on fracture alignment and comminution. MATERIALS AND METHODS: Six-hundred eighteen patients with DRF were treated in the medical center in 2007-2010. Seventy-six (12.3%) DRF who underwent two reductions were included in the study. Radiographs taken after the first and second reduction attempts were reviewed for changes in fracture alignment parameters (radial height, radial inclination, volar tilt) and dorsal comminution length. Patients were also followed retrospectively to determine the rates of secondary displacement in a cast. RESULTS: A second closed reduction attempt improved mean radial height by 1.43 mm, mean radial inclination by 1.62 degrees and mean volar tilt by 8.75 degrees . Mean dorsal comminution length increased by 1.6 mm. Of the 19 (25%) patients with acceptable alignments after two reduction attempts, follow-up radiographs were available for 12, which showed successful reduction in four cases (33.3 or 5.2% of total 76 patients). CONCLUSIONS: A second closed reduction attempt improved immediate fracture alignment, but also worsened dorsal comminution. Only 5.2% of patients who underwent two reduction attempts had an acceptable final alignment and did not require surgery. Increased dorsal comminution may further compromise fracture stability, complicate surgery and have negative effect on the postoperative course. PMID- 29453643 TI - The Effects of Mindfulness on Sexual Outcomes: The Role of Emotion Regulation. AB - Individuals higher in dispositional mindfulness, a quality of non-judgmental attention to the present moment, fare better than their less mindful counterparts on a wide range of psychological and interpersonal outcomes. However, remarkably little is known about the potential influence of dispositional mindfulness on sexual outcomes. Here we investigated whether dispositional mindfulness was associated with a range of sexual outcomes, including sexual satisfaction, sexual hyperactivation (heightened sexual desire and worry), sexual deactivation (suppression of sexual desire and behavior), and problematic pornography use. We also tested whether capacity for emotion regulation was the mechanism underlying the mindfulness-sexual outcome association. These hypotheses were tested in two samples: a sample of adults in a committed romantic relationship (N = 407) and a group of adults who were long-term single (N = 400). Across both samples, dispositional mindfulness predicted more adaptive sexual outcomes, and emotion regulation generally mediated these associations. Of particular importance, the positive effects of dispositional mindfulness on sexual outcomes appear to generalize across relationship statuses, with both partnered and long-term single individuals displaying a similar pattern of results. These findings highlight that high dispositional mindfulness may predict a range of positive sexual outcomes in both partnered and single individuals.

AB - BACKGROUND: Bladder cancer (BCa) is the seventh most common cancer among males worldwide. Some reliable markers in blood, urine, and tumor tissue, including clinicopathologic variables, molecular and inflammatory markers, gene polymorphisms, and tumor gene expression profiles are identified for predicting response to BCG immunotherapy in high-risk BCa patients. AIMS: We aimed to determine if FAS and FASL polymorphisms are associated with lack of response to BCG in patients with BCa. METHODS: The study included patients with primary non muscle invasive BCa that had undergone transurethral resection (TUR). Patient demographics, BCa characteristics, use of BCG immunotherapy, lack of response to BCG (if administered), BCa recurrence, and fatty acid synthetase/fatty acid syntethase ligand (FAS/FASL) polymorphisms were investigated. RESULTS: The study included 127 patients with primary BCa. Mean age of the 107 (84.3%) male and 20 (15.7%) female patients was 59.3 +/- 13.2 years. Among the patients that received BCG immunotherapy, more FAS homozygous patients had BCa recurrence than FAS polymorphism-negative patients (P < 0.001) and more patients with homozygote FASL polymorphisms had BCa recurrence than those with heterozygous FASL polymorphisms and no polymorphism. CONCLUSION: Evaluation of FAS/FASL polymorphisms can predict lack of response to BCG immunotherapy and prevent the loss of valuable time before such alternative treatments as early cystectomy are initiated. PMID- 29453646 TI - Estimation of Radionuclide Concentrations and Average Annual Committed Effective Dose due to Ingestion for the Population in the Red River Delta, Vietnam. AB - Radioactivity concentrations of nuclides of the 232Th and 238U radioactive chains and 40K, 90Sr, 137Cs, and 239+240Pu were surveyed for raw and cooked food of the population in the Red River delta region, Vietnam, using alpha-, gamma spectrometry, and liquid scintillation counting techniques. The concentration of 40K in the cooked food was the highest compared to those of other radionuclides ranging from (23 +/- 5) (rice) to (347 +/- 50) Bq kg-1 dw (tofu). The 210Po concentration in the cooked food ranged from its limit of detection (LOD) of 5 mBq kg-1 dw (rice) to (4.0 +/- 1.6) Bq kg-1 dw (marine bivalves). The concentrations of other nuclides of the 232Th and 238U chains in the food were low, ranging from LOD of 0.02 Bq kg-1 dw to (1.1 +/- 0.3) Bq kg-1 dw. The activity concentrations of 90Sr, 137Cs, and 239+240Pu in the food were minor compared to that of the natural radionuclides. The average annual committed effective dose to adults in the study region was estimated and it ranged from 0.24 to 0.42 mSv a-1 with an average of 0.32 mSv a-1, out of which rice, leafy vegetable, and tofu contributed up to 16.2%, 24.4%, and 21.3%, respectively. The committed effective doses to adults due to ingestion of regular diet in the Red River delta region, Vietnam are within the range determined in other countries worldwide. This finding suggests that Vietnamese food is safe for human consumption with respect to radiation exposure. PMID- 29453647 TI - New records and host associations of the tick Ixodes apronophorus and the first detection of Ehrlichia sp. HF in Romania. AB - Ixodes (Ixodes) apronophorus is a neglected tick species and its geographical distribution, host associations, and role as a disease vector are not well known. We collected I. apronophorus from several locations in Romania. Morphological identification of ticks was confirmed by analysis of 16S rDNA and 12S rDNA gene sequences. We report new host associations of I. apronophorus, which was collected from dogs, foxes, and a hare-all new hosts for this tick species in Romania. Furthermore, we report for the first time occurrence of Ehrlichia sp. HF in I. apronophorus. Ehrlichia sp. HF was identified by sequencing a part of the 16S rDNA gene and was found in 16% (3/19) of the tested ticks. Ehrlichia sp. HF has not been previously reported in Eastern Europe and seems to have a much larger geographic distribution than previously known. Currently, it is unknown whether I. apronophorus is a competent vector for Ehrlichia sp. HF, or if the findings in this study represent infection in the hosts, namely dogs and fox. PMID- 29453648 TI - Supplemental diagnosis of Gyrodactylus fairporti Van Cleave, 1921 (Monogenea) from 1 month old black bullhead (Ameiurus melas) in riverside pools in Wisconsin. AB - Samples of Gyrodactylus fairporti Van Cleave, 1921 from young-of-the-year black bullhead (Ameiurus melas) stranded in riverside pools of the Black River (La Crosse County,) WI, USA, are used to supplement the species diagnosis, including new details on the marginal hook sickles, the male copulatory organ (MCO), and 18S rRNA gene sequence data. The anchors of G. fairporti are relatively long and thin, 58.2 +/- 1.2 MUm in length; roots 15.5 +/- 1.0 MUm; shaft 38.1 +/- 1.5 MUm; point 31.3 +/- 1.5 MUm. The ventral bar is 19.4 +/- 0.4 MUm wide and 5.7 +/- 0.9 MUm long, with small anterolateral processes, 2.0 +/- 0.6 MUm long, and an almost rectangular posterior shield 15.5 +/- 1.1 MUm in length. The marginal hooks are 29.2 +/- 1.0 MUm long, with the handle 23.9 +/- 1.2 MUm in length. These measurements are similar to those reported from Iowa and Alabama, with the additional observation of the anchor point bending outwardly halfway along its length. The marginal hook sickle blade leaves the base angled ventrally away from the longitudinal axis; the sickle point is short; the toe has a rounded shelf and the heel is small, thin, and rounded. The MCO has eight small spines, two large ones laterally and the others of various lengths, with two of the smallest spines being slightly out-of-line compared with all the others. The taxonomy of G. fairporti is compared to Gyrodactylus ictaluri Rogers, 1967 and G. nebulosus Kritsky & Mizelle, 1967, the other two species known from captive and wild ictalurids endemic to North America. The three species all have a relatively compact ventral bar with short anterolateral processes, a short almost rectangular ventral bar membrane, an MCO with up to eight small spines of varying length, and a hook sickle angled ventrally. Diagnostically, the species are readily identified by the total length and shape of the anchors. G. fairporti bears the longest (53-65 MUm) and most slender anchors of the trio, G. nebulosus intermediate (49-51 MUm) and G. ictaluri with the shortest and stoutest (40-45 MUm) of these species. A BLAST search of a partial (413 bp) 18S rRNA gene showed the highest similarity with Gyrodactylus sp. reported from Ameiurus nebulosus (Siluriformes) in Ontario. PMID- 29453649 TI - Reinereins A and B, new onocerane triterpenoids from Reinwardtiodendron cinereum. AB - Bioactivity guided separation of Reinwardtiodendron cinereum barks methanol extract led to the isolation of two new onocerane triterpenoids, reinereins A and B (1 and 2), together with three known onocerane triterpenoids. Their structures were elucidated on the basis of NMR spectroscopic data. In vitro cytotoxic activities of the isolated compounds against several type of cancer cells were evaluated. PMID- 29453650 TI - Atmospheric PM2.5 Mercury in the Metropolitan Area of Mexico City. AB - In this study, atmospheric mercury concentration in airborne particulate matter with an aerodynamic diameter <= 2.5 um (PM2.5) was analyzed by ICP-MS. Samples were collected in the Mexico City Metropolitan Area (MCMA), during 2013, in five locations, Northwest, Northeast (NE), Central, Southwest and Southeast, along three seasons: dry warm, rainy, and dry cold (DC). It can be observed that NE shows the highest mercury concentration (p < 0.05), where pollution events were identified. The seasonal distribution shows that samples collected during DC present the highest concentration (p < 0.05). These results are in agreement with the distribution of important mercury industrial sources located in the northern urban area as well with the temperature and wind conditions during 2013. The comparison of data obtained in this work with those of similar previous studies clearly indicates a decrease, between 2006 and 2013, of mercury content in PM2.5 collected in MCMA. PMID- 29453651 TI - Neurotrophins in Asthma. AB - PURPOSE OF REVIEW: Asthma is a chronic airway disease that affects more than 300 million people worldwide. Current treatment focuses on symptomatic relief by temporally dampening inflammation and relaxing the airway. Novel combative strategies against asthma and hopefully a cure are yet to be developed. The goal of this review is to summarize recent literature on neurotrophins (NTs) in experimental models and clinical settings of asthma research. RECENT FINDINGS: We highlight studies of early phases of asthma that collectively reveal a profound impact of elevated NT levels following initial detrimental insults on long-term airway dysfunction. We hope this review will foster insights into the complex interaction between NTs, nerves, immune cells, and airway structural cells during a critical time window of development and disease susceptibility. Future studies are required to better understand the role of NTs in asthma pathophysiology and to evaluate whether NTs and their receptors may serve as new drug targets. PMID- 29453652 TI - Significance of the nonneoplastic renal parenchymal findings in robotic partial nephrectomy series. AB - AIM: To describe the pathological characteristics of the peritumoral non neoplastic renal parenchyma (NNRP) and to investigate their impact on long-term renal function after partial nephrectomy. MATERIALS AND METHODS: In our institutional robotic partial nephrectomy database, we identified 394 cases with pathological assessment of the NNRP and long-term postoperative renal functional follow-up. The NNRP was classified as normal (healthy renal parenchyma) or abnormal, based on the presence of arteriosclerosis, glomerulosclerosis, interstitial fibrosis, interstitial inflammation, and/or tubulopapillary hyperplasia. The primary outcome was a >= 20% decline in estimated glomerular filtration rate (eGFR) at 6 and 12 months after surgery. Multivariable analysis was used to assess the association between NNRP and eGFR decline, with adjustment for demographic, clinical, and tumor factors. RESULTS: Overall, 250 (63.5%) pathological specimens had abnormal NNRP features. The most prevalent isolated benign pathological feature was glomerulosclerosis (18.0%), followed by arteriosclerosis (16.8%), interstitial inflammation (12.4%), interstitial fibrosis (1.2%), and tubulopapillary hyperplasia (0.4%). The abnormal NNRP group was associated with older age (p = .01), preoperative diabetes mellitus (p = .01), and preoperative hypertension (p = .01). The preoperative eGFR was significantly lower in the abnormal NNRP group (p = .01). NNRP abnormalities were not significantly associated with eGFR decline at either 6 or 12 months. The only independent predictor of eGFR decline was warm ischemia time (p = .01), and this association was only observed at 12 months. CONCLUSION: NNRP features are associated with preoperative comorbidities and lower baseline eGFR; however, they are not independent predictors of long-term renal functional preservation after partial nephrectomy. PMID- 29453653 TI - Tight interplay in early pregnancy between follistatin and anti-mullerian hormone in women with polycystic ovarian syndrome (PCOS). AB - PURPOSE: Follistatin levels increase during the course of pregnancy and may play a role in ovarian arrest, reflected by the simultaneous decrease of anti mullerian-hormone (AMH) levels. The aim of the study was to investigate AMH and follistatin levels during the hormonal window at the beginning of pregnancy. Since both parameters are described as deregulated in polycystic ovarian syndrome (PCOS), subgroup analysis of PCOS patients may additionally elucidate their interplay and effects on ovarian activity. METHODS: Serum samples were retrospectively analyzed using the AMH Gen II ELISA and the Human Follistatin Quantikine ELISA Kit. Samples were collected longitudinally from 57 patients (32 with PCOS and 25 controls) before conception and during the first trimester. In 18 patients, measurements from the early and the late first trimester were available. Potential associations of AMH and follistatin levels with PCOS-related parameters were compared between the subgroups as well as longitudinally before and in the first trimester of pregnancy. For statistical analysis, the Spearman's correlation, Wilcoxon test, t test, Friedman test and multiple linear regression analysis was performed. RESULTS: In contrast to AMH, follistatin levels differed not between controls and PCOS patients before and in pregnancy. In both subgroups, AMH levels significantly decreased and follistatin levels significantly increased in longitudinally performed measurements before conceiving and in the first trimester of pregnancy. CONCLUSION: Follistatin levels are not suited as a biomarker for PCOS, but could be involved in suppressing ovarian activity, as reflected by AMH levels at the beginning of pregnancy. PMID- 29453654 TI - Uterine electrical activity, oxytocin and labor: translating electrical into mechanical. AB - PURPOSE: Uterine activity plays a crucial role in labor, especially when utero tonic materials are administered. We aimed to determine the electrical responsiveness of the uterine musculature to labor augmentation with oxytocin using electrical uterine myography (EUM) technology, and to assess whether the kinetics of the EUM device may serve as a predictor for successful vaginal delivery. METHODS: EUM prospectively measured electrical uterine activity in women with singleton gestations at term (>= 37 + 0 weeks) undergoing labor augmentation by oxytocin administration. The results were reported as the EUM index, which represented the mean electrical activity in 10-min intervals and measured in units of microwatt per second (mW/s). Measurements were performed at least 30 min before oxytocin initiation and until at least four contractions per 10 min were recorded by standard tocodynamometry. The delta EUM index was defined as the difference between the mean EUM index before and after the initiation of oxytocin. RESULTS: The mean EUM index increased significantly during oxytocin augmentation in all the parturients (P < 0.001). Mean and minimum (but not maximum) uterine electrical activity during oxytocin infusion correlated with the baseline uterine activity. The delta EUM index was not significantly affected by demographic or obstetric parameters. There was no correlation between the delta EUM index and time to delivery or the mean EUM index during oxytocin administration and time to delivery. CONCLUSIONS: Uterine electrical activity as evaluated by EUM is significantly intensified following oxytocin administration, regardless of obstetrical characteristics, and is correlated with the baseline uterine electrical activity prior to oxytocin infusion.

AB - Minerals or trace elements in small amount are essential nutrients for every plant, but when the internal concentration exceeds the threshold, these essential elements do create phytotoxicity. Plant responses to elemental stresses are very common due to different anthropogenic activities; however it is a complex phenomenon with individual characteristics for various species. To cope up with the situation, a plant produces a group of strategies both in proteomic and genomic level to overcome it. Controlling the metal stress is known to activate a multigene response resulting in the changes in various proteins, which directly affects almost all biological processes in a living cell. Therefore, proteomic and genomic approaches can be useful for elucidating the molecular responses under metal stress. For this, it is tried to provide the latest knowledge and techniques used in proteomic and genomic study during nutritional stress and is represented here in review form. PMID- 29453656 TI - The ferroportin-ceruloplasmin system and the mammalian iron homeostasis machine: regulatory pathways and the role of lactoferrin. AB - In the last 20 years, several new genes and proteins involved in iron metabolism in eukaryotes, particularly related to pathological states both in animal models and in humans have been identified, and we are now starting to unveil at the molecular level the mechanisms of iron absorption, the regulation of iron transport and the homeostatic balancing processes. In this review, we will briefly outline the general scheme of iron metabolism in humans and then focus our attention on the cellular iron export system formed by the permease ferroportin and the ferroxidase ceruloplasmin. We will finally summarize data on the role of the iron binding protein lactoferrin on the regulation of the ferroportin/ceruloplasmin couple and of other proteins involved in iron homeostasis in inflamed human macrophages. PMID- 29453657 TI - The effect of L-carnitine supplementation on serum leptin concentrations: a systematic review and meta-analysis of randomized controlled trials. AB - PURPOSE: The actual effects of L-carnitine administration on leptin serum level is inconsistent. In order to assess the efficacy of L-carnitine supplementation on serum leptin we conducted a meta-analysis of randomized controlled trials (RCTs). METHODS: Seven studies with 325 cases and 330 controls were included. The pooled weighted mean difference (WMD) was calculated by random-effects model. The heterogeneity across studies was evaluated by using Cochrane's Q and I2 tests. In addition, we carried out the metaninf command to test the effect of each individual study on the overall result. RESULTS: L-carnitine supplementation seemed to have no significant effect on serum leptin concentrations (WMD: -0.565 ng/mL; 95% CI: -2.417 to 1.287, p = 0.550). However, between-study heterogeneity was higher across all studies (I2 = 84.3%, p < 0.0001). Subgroup analysis to find the sources of heterogeneity showed that L-carnitine dosage (g) ( < 2 g: I2 = 00.0%, p = 0.408), and study population (diabetes: I2 = 46.7%, p = 0.153, and non diabetes: I2 = 15.1%, p = 0.317) were the potential sources of heterogeneity. Besides, a more significant reduction in serum leptin concentration was observed with a daily dose of >= 2 mg L-carnitine (WMD: -2.742 ng/mL; 95% CI: -3.039 to 2.444, p < 0.001), in diabetic patients (WMD: -2.946 ng/mL; 95% CI: -3.254 to 2.638, p < 0.001), and with intervention duration <12 weeks (WMD: -2.772 ng/mL; 95% CI: -3.073 to -2.471, p < 0.001). CONCLUSION: L-carnitine consumption does not reduce serum leptin significantly. However, a significant effect on leptin was observed in diabetic patients and patients who received doses more than 3 mg per day in the course of <12 weeks. PMID- 29453658 TI - High-intensity focused ultrasound (HIFU) therapy for benign thyroid nodules without anesthesia or sedation. AB - BACKGROUND: Thermal ablation of thyroid nodules has gained momentum due to the possibility to avoid surgery. High-intensity focused ultrasound (HIFU) allows thermal treatment by energy ultrasound beam inside the targeted zone. Aim of our study was to evaluate the effects of HIFU treatment using Beamotion mode without anesthesia. METHODS: Since 2016, patients with normal thyroid function, benign thyroid nodules with diameter no larger than 4 cm, and presenting local discomfort and/or compressive symptoms were treated by HIFU. We performed Beamotion HIFU and did not use anesthesia. Nodule size and thyroid function were evaluated before HIFU and 6 and 12 months later. Complications to therapy and tolerability of patients were also recorded. According to local ethical committee, for this retrospective study formal consent was not required. RESULTS: The final series included 26 nodules from 26 patients with estimated volume of 2.81 +/- 2.04 mL, treated by a power of 33.3 +/- 10.3 W/site and energy of 2.1 +/ 1.1 kJ. Nodules volume was significantly (p < 0.0001) reduced at 6 months of follow-up (1.83 +/- 1.63 mL), and further at 1 year (1.57 +/- 1.47 mL). Mean percentage of reduction over time of nodules was 48%. A 73% of patients described good comfort during treatment, 100% experienced good comfort just after therapy, and tolerability was high. No complications were recorded. At one 1 year of follow-up, 85% of subjects reported a reduction of local symptoms. CONCLUSIONS: HIFU therapy is effective in reducing size of thyroid nodules with major diameter below 4 cm and can be performed without anesthesia. PMID- 29453659 TI - Fracture risk in women with type II diabetes. Results from a historical cohort with fracture follow-up. AB - PURPOSE: To examine the independent association between type II diabetes and fracture risk in a population of predominantly postmenopausal women referred to a specialist clinic for osteoporosis evaluation. METHODS: Type II diabetes associated fracture risk were evaluated among to 229 patients with type II diabetes in a cohort of 6285 women followed on average (until major osteoporotic fracture (MOF), death or end of study) for 5.8 years. Information of fracture risk factors was obtained from a clinical database and from national registries. RESULTS: An elevated fracture risk was present. Prevalent fractures (43.7 vs. 33.2%, p = 0.0010) and prevalent MOF (26.2 vs. 20.5% p = 0.038) were more common among patients with type II diabetes. The unadjusted incident fracture risk was increased with a higher relative risk of 42%. An elevated MOF hazard ratio was present (HR = 1.726, p = 0.0006). Adjustment for prevalent osteoporosis and other possible confounders did not change this finding (HR = 1.558, p = 0.0207). CONCLUSIONS: An association between type II diabetes and an increased risk of MOF primarily driven by an increased hip fracture risk was documented. This finding was independent of the presence of osteoporosis. Clinicians need to be aware of and adjust for these findings when evaluating patients with diabetes. Additional research examining pathophysiological mechanisms are needed. PMID- 29453660 TI - Verification of candidate microRNA markers for parathyroid carcinoma. AB - PURPOSE: Parathyroid carcinoma (PCa) is a rare endocrine malignancy with poor prognosis and is often difficult to accurately diagnose both before and after surgery. Dysregulated microRNA (miRNA) levels have been identified in PCa using a limited number of samples. The aim of the present study was to verify a group of miRNA markers in a new series of samples to explore their potential significance in PCa diagnosis. METHODS: A total of 58 tissue samples, including 17 PCa lesions and 41 sporadic parathyroid adenomas (PAds), were obtained from 56 primary hyperparathyroidism (pHPT) patients. Candidate miRNAs (miR-139-5p, miR-155-5p, miR-222-3p, miR-26b-5p, miR-296-5p, miR-30b-5p, miR-372-3p, miR-503-5p, miR-517c 3p, miR-7-5p, and miR-126-5p) were quantified by TaqMan real-time quantitative PCR assays. RESULTS: Up-regulated miR-222 (p = 0.041) levels and down-regulated miR-139 (p = 0.003), miR-30b (p < 0.001), miR-517c (p = 0.038), and miR-126* (p = 0.002) levels were found in PCa relative to PAd. Binary logistic regression analysis showed that miR-139 and miR-30b were the best diagnostic markers. The combination of miR-139 and miR-30b yielded an area under the receiver operating characteristic curve of 0.888. Additionally, serum calcium (r s = -0.518, p < 0.001), intact parathyroid hormone (iPTH) (r s = -0.495, p < 0.001), and alkaline phosphatase (ALP) (r s = -0.523, p < 0.001) levels were negatively correlated with miR-30b levels. CONCLUSIONS: miR-139, miR-222, miR-30b, miR-517c, and miR-126* were differentially expressed between PCa and PAd. The combined analysis of miR-139 and miR-30b may be used as a potential diagnostic strategy for distinguishing PCa from PAd. PMID- 29453661 TI - Maize water status and physiological traits as affected by root endophytic fungus Piriformospora indica under combined drought and mechanical stresses. AB - MAIN CONCLUSION: Under combined drought and mechanical stresses, mechanical stress primarily controlled physiological responses of maize. Piriformospora indica mitigated the adverse effects of stresses, and inoculated maize experienced less oxidative damage and had better adaptation to stressful conditions. The objective of this study was to investigate the effect of maize root colonization by an endophytic fungus P. indica on plant water status, physiological traits and root morphology under combined drought and mechanical stresses. Seedlings of inoculated and non-inoculated maize (Zea mays L., cv. single cross 704) were cultivated in growth chambers filled with moistened siliceous sand at a matric suction of 20 hPa. Drought stress was induced using PEG 6000 solution with osmotic potentials of 0, - 0.3 and - 0.5 MPa. Mechanical stress (i.e., penetration resistances of 1.05, 4.23 and 6.34 MPa) was exerted by placing weights on the surface of the sand medium. After 30 days, leaf water potential (LWP) and relative water content (RWC), root and shoot fresh weights, root volume (RV) and diameter (RD), leaf proline content, leaf area (LA) and catalase (CAT) and ascorbate peroxidase (APX) activities were measured. The results show that exposure to individual drought and mechanical stresses led to higher RD and proline content and lower plant biomass, RV and LA. Moreover, increasing drought and mechanical stress severity increased APX activity by about 1.9- and 3.1-fold compared with the control. When plants were exposed to combined stresses, mechanical stress played the dominant role in controlling plant responses. P. indica-inoculated plants are better adapted to individual and combined stresses. The inoculated plants had greater RV, LA, RWC, LWP and proline content under stressful conditions. In comparison with non-inoculated plants, inoculated plants showed lower CAT and APX activities which means that they experienced less oxidative stress induced by stressful conditions. PMID- 29453662 TI - The overexpression of RXam1, a cassava gene coding for an RLK, confers disease resistance to Xanthomonas axonopodis pv. manihotis. AB - MAIN CONCLUSION: The overexpression of RXam1 leads to a reduction in bacterial growth of XamCIO136, suggesting that RXam1 might be implicated in strain-specific resistance. Cassava bacterial blight (CBB) caused by Xanthomonas axonopodis pv. manihotis (Xam) is a prevalent disease in all regions, where cassava is cultivated. CBB is a foliar and vascular disease usually controlled through host resistance. Previous studies have found QTLs explaining resistance to several Xam strains. Interestingly, one QTL called XM5 that explained 13% of resistance to XamCIO136 was associated with a similar fragment of the rice Xa21-resistance gene called PCR250. In this study, we aimed to further identify and characterize this fragment and its role in resistance to CBB. Screening and hybridization of a BAC library using the molecular marker PCR250 as a probe led to the identification of a receptor-like kinase similar to Xa21 and were called RXam1 (Resistance to Xam 1). Here, we report the functional characterization of susceptible cassava plants overexpressing RXam1. Our results indicated that the overexpression of RXam1 leads to a reduction in bacterial growth of XamCIO136. This suggests that RXAM1 might be implicated in strain-specific resistance to XamCIO136. PMID- 29453663 TI - The rice "fruit-weight 2.2-like" gene family member OsFWL4 is involved in the translocation of cadmium from roots to shoots. AB - MAIN CONCLUSION: Heterogeneous expression of the rice genes "fruit-weight 2.2 like" (OsFWL) affects Cd resistance in yeast, and OsFWL4 mediates the translocation of Cd from roots to shoots. Cadmium (Cd) induces chronic and toxic effects in humans. In a previous study (Xu et al. in Planta 238:643-655, 2013), we cloned the rice genes, designated OsFWL1-8, homologous to the tomato fruit weight 2.2. Here, we show that expression of genes OsFWL3-7 in yeast confers resistance to Cd. The Cd contents of OsFWL3-, -4-, -6- and -7-transformed Cd(II) sensitive yeast mutant ycf1 cells were strongly decreased compared with those of empty vector, with the strongest resistance to Cd observed in cells expressing OsFWL4. Evaluation of truncated and site-directed mutation derivatives revealed that the CCXXG motifs near the second transmembrane region of OsFWL4 are involved in Cd resistance in yeast. Real-time PCR analysis showed that OsFWL4 expression was induced by CdCl2 stress in rice seedlings. Compared with WT plants, the Cd contents in the shoots of RNAi mediated OsFWL4 knockdown plants were significantly decreased, and Cd translocation from roots to shoots was reduced. According to bimolecular fluorescence complementation, yeast two-hybrid and Western-blotting assays, the OsFWL4 protein forms homo-oligomers. These results suggest that OsFWL4 might act directly as a transporter and is involved in the translocation of Cd from roots to shoots in rice. PMID- 29453664 TI - Analysis of transactivation potential of rice (Oryza sativa L.) heat shock factors. AB - MAIN CONCLUSION: Based on yeast one-hybrid assays, we show that the presence of C terminal AHA motifs is not a prerequisite for transactivation potential in rice heat shock factors. Transcriptional activation or transactivation (TA) of heat stress responsive genes takes place by binding of heat shock factors (Hsfs) to heat shock elements. Analysis of TA potential of thirteen rice (Oryza sativa L.) Hsfs (OsHsfs) carried out in this study by yeast one-hybrid assay showed that OsHsfsA3 possesses strong TA potential while OsHsfs A1a, A2a, A2b, A4a, A4d, A5, A7b, B1, B2a, B2b, B2c and B4d lack TA potential. From a near complete picture of TA potential of the OsHsf family (comprising of 25 members) emerging from this study and an earlier report from our group (Mittal et al. in FEBS J 278(17):3076 3085, 2011), it is concluded that (1) overall, six OsHsfs, namely A3, A6a, A6b, A8, C1a and C1b possess TA potential; (2) four class A OsHsfs, namely A3, A6a, A6b and A8 have TA potential out of which A6a and A6b contain AHA motifs while A3 and A8 lack AHA motifs; (3) nine class A OsHsfs, namely A1a, A2a, A2b, A2e, A4a, A4d, A5, A7a and A7b containing AHA motif(s) lack TA function in the yeast assay system; (4) all class B OsHsfs lack AHA motifs and TA potential (B4a not analyzed) and (5) though all class C OsHsf members lack AHA motifs, two members C1a and C1b possess TA function, while one member C2a lacks TA potential (C2b not analyzed). Thus, the presence or absence of AHA motif is possibly not the only factor determining TA potential of OsHsfs. Our findings will help to identify the transcriptional activators of rice heat shock response. PMID- 29453665 TI - Klaus Apel (1942-2017): a pioneer of photosynthesis research. AB - We present here a Tribute to Klaus Apel (1942-2017), a photosynthesis pioneer-an authority on plant molecular genetics-in five parts. The first section is a prologue. The second section deals with a chronological discussion of Apel's research life, prepared by the editor Govindjee; it is based on a website article at the Boyce Thompson Institute (BTI) by Patricia Waldron ( https://btiscience.org/explore-bti/news/post/bti-says-goodbye-klaus-apel/ ), as approved for use here by Keith C. Hannon and David Stern of BTI. The third section, which focuses on Apel's pioneering work on singlet oxygen-mediated EXECUTER-dependent signaling in plants, is written by two of us (J-DR and CK). The fourth section includes three selected reminiscences, one from BTI and two from ETH (Eidgenossische Technische Hochschule). This tribute ends with section five, which is a very brief presentation of Klaus Apel's personal life, by Wiebke Apel. PMID- 29453666 TI - Comments on "A Mathematical Study to Control Visceral Leishmaniasis: An Application to South Sudan". AB - Deterministic (ordinary differential equation) models for the transmission dynamics of vector-borne diseases that incorporate disease-induced death in the host(s) population(s) are generally known to exhibit the phenomenon of backward bifurcation (where a stable disease-free equilibrium of the model coexists with a stable endemic equilibrium when the associated reproduction number of the model is less than unity). Further, it is well known that, in these models, the phenomenon of backward bifurcation does not occur when the disease-induced death rate is negligible (e.g., if the disease-induced death rate is set to zero). In a recent paper on the transmission dynamics of visceral leishmaniasis (a disease vectored by sandflies), titled "A Mathematical Study to Control Visceral Leishmaniasis: An Application to South Sudan," published in Bulletin of Mathematical Biology, Vol. 79, Pages 1110-1134, 2017, Ghosh et al. (2017) stated that their deterministic model undergoes a backward bifurcation even when the disease-induced mortality in the host population is set to zero. This result is contrary to the well-established theory on the dynamics of vector-borne diseases. In this short note, we illustrate some of the key errors in the Ghosh et al. (2017) study. PMID- 29453667 TI - Dissolved organic matter characteristics along sabo dammed streams based on ultraviolet visible and fluorescence spectral properties. AB - Changes in dissolved organic matter (DOM) characteristics were investigated in two mountainous streams with closed-type sabo dams. Surface water was collected from four stations along the two mountainous streams and analyzed using ultraviolet-visible spectrophotometry and excitation-emission fluorescence matrix (EEM) methods. Optical properties of DOM indicated an increase in molecular weight and aromaticity at stations near the sabo dams. Average spectral ratio values were low before and after the dam (i.e., < 0.72) compared to other sections of the stream. Specific ultraviolet absorbance (SUVA254) increased in the vicinities of the dams. While chromophoric DOM characteristics from two sites were influenced by the dam, fluorescence components, however, did not show notable changes around dams. Instead, the three chromophoric components distinguished by EEM-parallel factor analysis, that is, humic-like (C1 and C2) and protein-like (C3) increase along the stream. Fulvic-like component (C1) had a high fluorescence intensity at all stations; all the three components were more abundant in the downstream section. Chromophoric DOM properties varied along the stream based on alterations in molecular size and aromaticity. Using multivariate analysis, the studied sites were grouped into three clusters related to sabo dams and other activities. We conclude that sabo dams modify DOM characteristics which influence the behavior of DOM transported along the stream. PMID- 29453668 TI - Netarsudil Ophthalmic Solution 0.02%: First Global Approval. AB - Netarsudil ophthalmic solution 0.02% (hereafter referred to as netarsudil 0.02%) [Rhopressa(r)] is a Rho-associated protein kinase inhibitor that is thought to lower intraocular pressure (IOP) by increasing aqueous humour outflow through the trabecular meshwork. It has been developed by Aerie Pharmaceuticals and was recently approved in the USA for the reduction of elevated IOP in patients with open-angle glaucoma or ocular hypertension. The recommended dosage is one drop in the affected eye(s) once daily in the evening. Phase III development in the EU and phase II development in Japan are underway for this indication. This article summarizes the milestones in the development of netarsudil 0.02% leading to this first approval for the reduction of elevated IOP in patients with open-angle glaucoma or ocular hypertension. PMID- 29453669 TI - Physical Training and Cardiac Rehabilitation in Heart Failure Patients. AB - Regardless of advances in medical and interventional treatment of cardiovascular disease (CVD), a limited number of patients attend a cardiac rehabilitation (CR) programme on a regular basis. Due to modern therapies more individuals will be surviving an acute cardiovascular event, but the expected burden of chronic heart failure will be increasing worldwide.However, both in high- and low-income countries, secondary prevention after an acute myocardial infarction or stroke has been implemented in less than a half of eligible patients.Combined interventions are still needed to reduce decompensations, hospitalizations and mortality in heart failure patients from any origin. In addition to medical treatments, regular exercise has been demonstrated to improve metabolic and hemodynamic conditions in both asymptomatic risk factor carriers and cardiac patients. Risk factor control and exercise should gather together for an effective management of patients.Exercise-based training is a core component of primary and secondary prevention. It should involve healthy carriers of cardiovascular risk factors, and patients with cardiomyopathy as well. The supposed attenuated effect of CR in the era of advanced revascularization and structural interventions is due to the heterogeneity of training models and physical training in the literature. Moreover, lifestyle modification, psycho social challenges and patient's compliance are potential confounders.In this chapter the most recent evidences about training modalities and potential benefit of CR in heart failure patients are discussed. PMID- 29453670 TI - Incidence and Drug Resistance of Zoonotic Mycobacterium bovis Infection in Peshawar, Pakistan. AB - Prevalence of zoonotic Mycobacterium bovis (bTB) disease in human population is underreported from the North of Pakistan. Here, we report on the proportion of human bTB disease among the overall TB patients, drug resistance pattern of bTB isolates, and knowledge, attitude, and practices (KAP)-based analysis of bTB disease. For this purpose, sputum samples from a total of 300 clinically diagnosed TB patients and 100 randomly selected school children suspected of pulmonary TB were processed by culture as well as polymerase chain reaction (PCR) for isolation, identification, and confirmation of Mycobacterium tuberculosis (mTB) and bTB species. Isolates of bTB were processed for drug susceptibility tests. Data on KAP regarding TB were obtained on a pretested questionnaire. Sputum-based PCR results indicated that 288/300 (96%) were confirmed as mTB, while 12/300 (4%) were found as bTB diseases. Interestingly, none of the school child was declared positive for either mTB or bTB. Notably, 274/300 (91.3%) positively cultured samples were identified as mTB, 13/300 (4.3%) as bTB, while 5/300 (1.7%) as mixed containing both. Importantly, except one, all of the bTB isolates were found resistant to pyrazinamide. Surprisingly, most of the bTB isolates (~70%) were found resistant to a broad range of first- and second-line anti-TB drugs. SplitsTree and recombination analysis indicated no evidence of intergenic recombination. Finally, residence, occupation, presence of animals at home, and sleeping alongside animals were found significantly associated with occurrence of bTB disease. To the best of our knowledge, we report for the first time on the high (4%) burden of bTB disease in human TB patients in Peshawar, Pakistan. PMID- 29453671 TI - Comparative evaluation of pharmacokinetics and pharmacodynamics of insulin glargine (Glaritus(r)) and Lantus(r) in healthy subjects: a double-blind, randomized clamp study. AB - AIMS: The objective of the study was to compare the pharmacokinetic (PK) and pharmacodynamic (PD) properties of an insulin glargine formulation, Glaritus(r) (test) with the innovator's formulation Lantus(r) (reference) using the euglycemic clamp technique in a single-dose, double-blind, randomized, two sequences, four-period replicate crossover study in healthy volunteers (n = 40). METHODS: Subjects received subcutaneous administration of the insulin glargine (0.4 IU/kg) formulation at two occasions for test and reference and a 20% glucose solution was infused at variable rate to maintain euglycemia for 24 h. RESULTS: Both PK [area under the plasma concentration time curve (AUC0-24 h) and maximum insulin concentration (Cmax)] and PD endpoints [area under glucose infusion rate time curve (AUCGIR0-24) and maximum glucose infusion rate (GIRmax)] demonstrated bioequivalence of Glaritus to Lantus with the 90% confidence interval of geometric mean ratio of test to reference entirely contained within 0.80-1.25. Both formulations showed equivalent geometric least-square mean LSM value (0.08 nmol/L) for Cmax. The geometric LSM AUC0-24 h value for Glaritus(r) (1.09 h nmol/L) was comparable to Lantus (1.05 h nmol/L). Median Tmax values were also identical (12 h for both), and median t1/2 values were also equal (18 h for both). For GIRTmax, the difference between the means for the two was not statistically significant. No AEs related to study formulations were reported, and both products were well tolerated. CONCLUSIONS: The test product (Glaritus) was found to be bioequivalent to the reference product (Lantus). CLINICAL TRIAL REGISTRATION NUMBER: CTRI/2015/06/005890; http://www.ctri.nic.in/ . PMID- 29453672 TI - The effect of n-3 PUFAs on circulating adiponectin and leptin in patients with type 2 diabetes mellitus: a systematic review and meta-analysis of randomized controlled trials. AB - AIM: N-3 PUFAs can potentially influence levels of inflammatory and non inflammatory adipokines. Given the contradictory effects of n-3 PUFAs on serum levels of adipokines in type 2 diabetes, we conducted a systematic review and meta-analysis study of randomized placebo-controlled clinical trials that examined the effects of n-3 PUFAs on serum levels of leptin and adiponectin in patients with type 2 diabetes. METHODS: The electronic databases, without regard to language restrictions including PubMed/Medline, Google Scholar, SCOPUS and ISI Web of Science until August 2017, were used to identify randomized controlled trials that assessed the effect of n-3 PUFAs on serum leptin and adiponectin concentrations in type 2 diabetes. Outcomes were extracted based on the mean +/- SD as effect size at baseline and end of the intervention. Between-study heterogeneity was evaluated by the I2 estimates and their 95% CIs. Funnel plot asymmetry was used to investigate the existence of publication bias. Stata software and Review Manager were used for statistical data analysis. RESULTS: Data from 10 eligible articles involved 494 subjects with type 2 diabetes mellitus (intervention groups = 254 and control groups = 240), with age between 44 and 70 years, treated with doses of 0.52-7.4 g/day n-3 PUFAs. Adiponectin concentration nonsignificantly increased by a MD = 0.17 ug/mL (95% CI - 0.11, 0.44). Also, leptin concentration nonsignificantly reduced by a MD = - 0.31 ng/mL (95% CI - 0.69, 0.07). CONCLUSION: Plant and marine sources of n-3 PUFAs can modify serum leptin and adiponectin levels by increasing adiponectin and decreasing leptin levels in patients with type 2 diabetes. Due to some limitations in this study, further studies are needed to reach a definitive conclusion about the effect of n-3 PUFAs on the levels of leptin and adiponectin in T2DM. PMID- 29453674 TI - Contrast-enhanced ultrasonography of post-interventional hematoma: the bleeding mushroom is growing inside. AB - Catheter ablation is an effective treatment in patients with symptomatic atrial fibrillation. Complications are infrequent and usually resolve with minimal or no intervention, but active bleeding due to arterial injury during the vascular access can sometimes represent a life-threatening complication. Contrast-enhanced computed tomography is the standard technique to detect active bleeding, but it may not be immediately available. We report a case of iatrogenic hemorrhage after catheter ablation, in which contrast-enhanced ultrasonography played a decisive role in the recognition of active arterial bleeding due to injury to the right common femoral artery. PMID- 29453673 TI - Optical coherence tomography angiography discerns preclinical diabetic retinopathy in eyes of patients with type 2 diabetes without clinical diabetic retinopathy. AB - AIMS: To investigate changes in retinal vascular plexuses and choriocapillaris in patients with type 2 diabetes mellitus (DM2) without diabetic retinopathy (DR) and healthy controls using optical coherence tomography angiography (OCTA). METHODS: A total of 71 DM2 and 67 healthy control subjects were included. All subjects underwent OCTA examination (RTVue-XR Avanti; Optovue, Fremont, CA, USA). Average vessel density in superficial capillary plexus (SCP), deep capillary plexus (DCP) and choriocapillaris, parafoveal vessel density in SCP and DCP, FAZ area (mm2) in SCP, microaneurysms and capillary nonperfusion were taken into analysis. RESULTS: Parafoveal vessel density in both SCP and DCP decreased in the eyes without clinical DR compared to normal controls (p < 0.001). Diabetic patients with no signs of DR also had a significant reduction in average vessel density of SCP, DCP and choriocapillaris (p < 0.001, p < 0.001 and p = 0.006, respectively). No significant difference was found in FAZ area of SCP between DM2 eyes and healthy controls (p = 0.253). The average vessel density of SCP and DCP is not correlated with HbA1c or serum creatinine in DM2 patients. Microaneurysms seen in OCTA but not in fundus examination were found in 8 out of the 71 (11.3%) diabetic eyes, and capillary nonperfusion was noted in 18 of 71 diabetic eyes. CONCLUSIONS: We demonstrated that OCTA can identify preclinical DR before the manifestation of clinically apparent retinopathy in diabetic eyes. DM2 patients without DR have SCP, DCP and choriocapillaris impairment. Our results suggested that OCTA might be a promising tool for regular screening of diabetic eyes for DR.

AB - PURPOSE: The purpose of this study was to compare the carotid artery wall elasticity between patients with uremia and controls using echo tracking (ET). METHODS: Ninety-three patients with uremia and 35 control subjects (Group A) were enrolled in this study. In the ET mode, the carotid artery elasticity parameters including stiffness index (beta), pressure-strain elasticity modulus (EP), arterial compliance (AC), and one-point pulse wave velocity (PWVbeta) were measured, and carotid intima-media thickness (IMT) was measured with B-mode ultrasonography. The patients were classified into three groups: Group B (normal IMT), Group C (thickened IMT), and Group D (one single atheroma plaque). RESULTS: beta, EP, and PWVbeta were significantly higher in Group B, C, and D (especially in group D) than those of the control group (P < 0.05), and there were significant differences between Group A and Group B, while AC was lower than in controls, but there were no statistically significant differences among the four groups. CONCLUSIONS: ET is a noninvasive method that can demonstrate a loss in carotid artery elasticity in uremia patients with normal IMT.

AB - Bacterial communities of biofilms growing on artificial substrates were examined at two time periods (7 and 14 days) and two locations (lentic and lotic areas) in a hypereutrophic urban river of eastern China. Previous studies in this river network indicated that variations of microbial communities were the major factor affecting the distribution of antibiotic resistant genes highlighting the importance of understanding controls of microbial communities. Bacterial communities associated with biofilms were determined using epifluorescence microscopy and high-throughput sequencing. Results showed that sampling time and site had significant effects on the abundances of surface-associated bacteria. No significant differences were found in the number of surface-associated bacteria between two substrate types (filament vs. slide). Sequencing revealed microbial communities attached to artificial substrates in a hypereutrophic urban river were composed of 80,375 OTUs, and distributed in 47 phyla. Proteobacteria and Cyanobacteria/Chloroplast were the two dominant phyla, followed by Planctomycetes, Actinobacteria, Verrucomicrobia, Firmicutes and Bacteroidetes. Taxonomic composition showed ammonia-oxidizing microorganisms, fecal indicator bacteria and pathogens enriched in attached microbial communities, especially the ammonia-oxidizing Nitrosomonas bacteria. These results indicated that there were significant temporal and intra-river heterogeneity of attached microbial community structure, but no significant difference in community composition was detected between the two substrate types.

AB - Background The more (inappropriate) drugs a patient uses, the higher the risk of drug related problems. To reduce these risks, medication reviews can be performed. Objective To report changes in the prescribed number of (potentially inappropriate) drugs before and after performing a medication review in high-risk polypharmacy patients. A secondary objective was to study reasons for continuing potentially inappropriate drugs (PIDs). Setting Dutch community pharmacy and general medical practice. Methods A retrospective longitudinal intervention study with a pre-test/post-test design and follow-up of 1 week and 3 months was performed. The study population consisted of 126 patients with polypharmacy and with additional risk for drug related problems that underwent a medication review in five community pharmacies. The medication review was performed by the pharmacist in close cooperation with the general practitioner of each corresponding patient. Main outcome measure Number of (potentially inappropriate) drugs, and appropriateness of prescribed medicines. Results The average number of drugs a patient used 1 day before the review was 8.7 (SD = 2.9), which decreased (p < 0.05) to 8.3 (SD = 2.7) 1 week after the review, and to 8.4 (SD = 2.6) 3 months after the review. The average number of PIDs was initially 0.6 (SD = 0.8) per patient and decreased to 0.4 (SD = 0.6, p < 0.05). Twenty-two of the 241 initial drug changes (9%) were deprescribed during follow-up. Registered reasons for continuing PIDs are clinical or patients' preferences. Conclusions Performing medication reviews in polypharmacy patients seems useful to continue at least in high-risk patients in The Netherlands. The time-consuming reviews could be limited to patients who are willing to change their medication. PMID- 29453679 TI - The impact of timing of immunotherapy with cranial irradiation in melanoma patients with brain metastases: intracranial progression, survival and toxicity. AB - Immunotherapy (IT) is increasingly incorporated in the management of metastatic melanoma patients with brain metastases, but the impact of timing of IT with stereotactic radiosurgery (SRS) remains unclear. The aim of this study was to determine the temporal significance of IT in melanoma patients treated with cranial radiation therapy (RT) with respect to patterns of intracranial progression, overall survival (OS), and toxicity. We retrospectively reviewed consecutive melanoma patients with brain metastases undergoing cranial RT and IT between 2008 and 2015. Concurrent IT/RT was defined as IT administration within 30 days of RT. Intracranial progression, OS and radionecrosis were assessed. We identified 74 patients with 136 treated brain metastases. Median OS was 13.9 months. Performance status, pre-SRS surgery, and intracranial progression were correlated with OS. Concurrent IT/RT was used in 35 (47.3%) patients. Patients receiving concurrent IT/RT were less likely to have a BRAF mutation (p = 0.027) and more likely to be treated after 2013 (p = 0.010) compared to non-concurrently treated patients. Patients receiving concurrent IT/RT were more likely to have intracranial progression within 60-days (54.3% vs. 30.8%, p = 0.041). However, 25.7% of concurrent IT/RT patients attained >= 1 year intracranial progression free survival. There were no significant differences in symptomatic radionecrosis (11.4% vs. 12.8%, p = 0.67). In conclusion, although melanoma patients with brain metastases receiving concurrent IT/RT were more likely to exhibit early intracranial disease progression, a significant proportion of non-early progressors attained durable intracranial control. The combination of IT and cranial RT appears to be efficacious and safe. Prospective studies are required to clarify these retrospective findings. PMID- 29453678 TI - Differential expression of the TWEAK receptor Fn14 in IDH1 wild-type and mutant gliomas. AB - The TNF receptor superfamily member Fn14 is overexpressed by many solid tumor types, including glioblastoma (GBM), the most common and lethal form of adult brain cancer. GBM is notable for a highly infiltrative growth pattern and several groups have reported that high Fn14 expression levels can increase tumor cell invasiveness. We reported previously that the mesenchymal and proneural GBM transcriptomic subtypes expressed the highest and lowest levels of Fn14 mRNA, respectively. Given the recent histopathological re-classification of human gliomas by the World Health Organization based on isocitrate dehydrogenase 1 (IDH1) gene mutation status, we extended this work by comparing Fn14 gene expression in IDH1 wild-type (WT) and mutant (R132H) gliomas and in cell lines engineered to overexpress the IDH1 R132H enzyme. We found that both low-grade and high-grade (i.e., GBM) IDH1 R132H gliomas exhibit low Fn14 mRNA and protein levels compared to IDH1 WT gliomas. Forced overexpression of the IDH1 R132H protein in glioma cells reduced Fn14 expression, while treatment of IDH1 R132H overexpressing cells with the IDH1 R132H inhibitor AGI-5198 or the DNA demethylating agent 5-aza-2'-deoxycytidine increased Fn14 expression. These results support a role for Fn14 in the more aggressive and invasive phenotype associated with IDH1 WT tumors and indicate that the low levels of Fn14 gene expression noted in IDH1 R132H mutant gliomas may be due to epigenetic regulation via changes in DNA methylation. PMID- 29453680 TI - Prognostic implications of 62Cu-diacetyl-bis (N4-methylthiosemicarbazone) PET/CT in patients with glioma. AB - OBJECTIVE: The potential of positron emission tomography/computed tomography using 62Cu-diacetyl-bis (N4-methylthiosemicarbazone) (62Cu-ATSM PET/CT), which was originally developed as a hypoxic tracer, to predict therapeutic resistance and prognosis has been reported in various cancers. Our purpose was to investigate prognostic value of 62Cu-ATSM PET/CT in patients with glioma, compared to PET/CT using 2-deoxy-2-[18F]fluoro-D-glucose (18F-FDG). METHOD: 56 patients with glioma of World Health Organization grade 2-4 were enrolled. All participants had undergone both 62Cu-ATSM PET/CT and 18F-FDG PET/CT within mean 33.5 days prior to treatment. Maximum standardized uptake value and tumor/background ratio were calculated within areas of increased radiotracer uptake. The prognostic significance for progression-free survival and overall survival were assessed by log-rank test and Cox's proportional hazards model. RESULTS: Disease progression and death were confirmed in 37 and 27 patients in follow-up periods, respectively. In univariate analysis, there was significant difference of both progression-free survival and overall survival in age, tumor grade, history of chemoradiotherapy, maximum standardized uptake value and tumor/background ratio calculated using 62Cu-ATSM PET/CT. Multivariate analysis revealed that maximum standardized uptake value calculated using 62Cu-ATSM PET/CT was an independent predictor of both progression-free survival and overall survival (p < 0.05). In a subgroup analysis including patients of grade 4 glioma, only the maximum standardized uptake values calculated using 62Cu-ATSM PET/CT showed significant difference of progression-free survival (p < 0.05). CONCLUSIONS: 62Cu-ATSM PET/CT is a more promising imaging method to predict prognosis of patients with glioma compared to 18F-FDG PET/CT. PMID- 29453681 TI - 18F-FPYBF-2, a new F-18 labelled amyloid imaging PET tracer: biodistribution and radiation dosimetry assessment of first-in-man 18F-FPYBF-2 PET imaging. AB - OBJECTIVE: Recently, a benzofuran derivative for the imaging of beta-amyloid plaques, 5-(5-(2-(2-(2-18F-fluoroethoxy)ethoxy)ethoxy)benzofuran-2-yl)- N methylpyridin-2-amine (18F-FPYBF-2) has been validated as a tracer for amyloid imaging and it was found that 18F-FPYBF-2 PET/CT is a useful and reliable diagnostic tool for the evaluation of AD (Higashi et al. Ann Nucl Med, https://doi.org/10.1007/s12149-018-1236-1 , 2018). The aim of this study was to assess the biodistribution and radiation dosimetry of diagnostic dosages of 18F FPYBF-2 in normal healthy volunteers as a first-in-man study. METHODS: Four normal healthy volunteers (male: 3, female: 1; mean age: 40 +/- 17; age range 25 56) were included and underwent 18F-FPYBF-2 PET/CT study for the evaluation of radiation exposure and pharmacokinetics. A 10-min dynamic PET/CT scan of the body (chest and abdomen) was performed at 0-10 min and a 15-min whole-body static scan was performed six times after the injection of 18F-FPYBF-2. After reconstructing PET and CT image data, individual organ time-activity curves were estimated by fitting volume of interest data from the dynamic scan and whole-body scans. The OLINDA/EXM version 2.0 software was used to determine the whole-body effective doses. RESULTS: Dynamic PET imaging demonstrated that the hepatobiliary and renal systems were the principal pathways of clearance of 18F-FPYBF-2. High uptake in the liver and the gall bladder, the stomach, and the kidneys were demonstrated, followed by the intestines and the urinary bladder. The ED for the adult dosimetric model was estimated to be 8.48 +/- 1.25 uSv/MBq. The higher absorbed doses were estimated for the liver (28.98 +/- 12.49 and 36.21 +/- 15.64 uGy/MBq), the brain (20.93 +/- 4.56 and 23.05 +/- 5.03u Gy/MBq), the osteogenic cells (9.67 +/- 1.67 and 10.29 +/- 1.70 uGy/MBq), the small intestines (9.12 +/- 2.61 and 11.12 +/- 3.15 uGy/MBq), and the kidneys (7.81 +/- 2.62 and 8.71 +/- 2.90 uGy/MBq) for male and female, respectively. CONCLUSIONS: The ED for the adult dosimetric model was similar to those of other agents used for amyloid PET imaging. The diagnostic dosage of 185-370 MBq of 18F-FPYBF-2 was considered to be acceptable for administration in patients as a diagnostic tool for the evaluation of AD. PMID- 29453682 TI - Persistent Pulmonary Hypertension and Histologic Chorioamnionitis in Preterm Infants: Controlled Study. AB - Persistent pulmonary hypertension (PPHN) of the newborn is one of the most challenging acute disorders of postnatal transition with substantial morbidity and mortality. The aim of the study was to find if there is an association between persistent pulmonary hypertension and histologic chorioamnionitis in preterm infants. 27 preterm infants with echocardiographic evidence of PPHN within the first 3 days of life were eligible for the study. A matched control group of 27 patients was chosen according to gestational age, date of birth, and gender. Data collection included the need for respiratory support, use of nitric oxide oxygen supplementation, duration of rupture of membranes, blood culture, blood count, and C-reactive protein levels at birth and 12 h. Maternal clinical and laboratory data suggesting clinical chorioamnionitis Placentas of both groups were examined. Differences between groups were analyzed using two-tail t test, Kolmogorov-Smirnov test, Chi-square test. No statistically differences were found in all parameters compared between groups, except for a higher number of patients in the PPHN group who were treated by oxygen supplementation. An association was not found between the incidence of HCA and echocardiographic PPHN in preterm infants in the first 3 days of life. PMID- 29453683 TI - Flow Energy Loss as a Predictive Parameter for Right Ventricular Deterioration Caused by Pulmonary Regurgitation After Tetralogy of Fallot Repair. AB - The optimal timing for pulmonary valve replacement after Tetralogy of Fallot (TOF) repair remains controversial. In this study, we estimated the feasibility of using flow energy loss (FEL) to predict right ventricular (RV) deterioration due to pulmonary regurgitation after TOF repair. We examined RV outflow tract (RVOT) flow in nine patients who underwent TOF or double-outlet right ventricle repair in the intervention group (Group I) and compared them with three healthy children in the control group (Group C). We evaluated flow across the RVOT and pulmonary valve by vector flow mapping (VFM) on echocardiography and by phase contrast-magnetic resonance imaging (PC-MRI). Next, we calculated FEL and analyzed the relationship between FEL and clinical parameters of RV function. The mean FEL was significantly greater in Group I than in Group C (p = 0.002). Flow pattern and FEL were comparable by VFM and PC-MRI at the same phase 14.6 years after TOF repair. There was a significant positive correlation for the cardiothoracic ratio with both the mean FEL [correlation coefficient (r) = 0.78; p = 0.012] and the diastolic peak FEL (r = 0.75; p = 0.021) in Group I. There was also a significant positive correlation between the serial change in QRS duration with both the mean FEL (r = 0.82; p = 0.014) and the diastolic FEL (r = 0.70; p = 0.052) in Group I. FEL by VFM is an effective tool for evaluating ventricular deterioration caused by RV workload. PMID- 29453685 TI - Transcatheter Closure of Arterial Duct in Infants < 6 kg: Amplatzer Duct Occluder Type I vs Amplatzer Duct Occluder II Additional Sizes. AB - Transcatheter closure of arterial duct (AD) remains challenging in low-weight patients and using Amplatzer Duct Occluder devices is still considered off-label in infants < 6 kg. This study aimed to report a large, single-center experience of percutaneous AD closure in infants < 6 kg as well as to compare the most frequently used devices, Amplatzer Duct Occluder type I (ADO I) and Amplatzer Duct Occluder type II Additional Sizes devices (ADO II-AS) (St. Jude Medical Corp, St. Paul, MN, USA). From March 2000 to March 2017, among the 762 patients submitted to percutaneous closure of AD at our Institution, 33 were infants < 6 kg (age 4.8 +/- 2.1 months; weight 5.0 +/- 0.9 kg). Fourteen patients (45%) underwent ADO I (Group I) and 19 patients ADO II-AS (Group II) device implantation. AD diameter was 2.6 +/- 0.8 (range 1.5-4.0) mm resulting in QP/QS of 2.6 +/- 0.0.9 (range 1.1-4.5). Successful device deployment was achieved in all patients without procedural morbidity or mortality. Procedural and fluoroscopy times were not significantly different between the groups. However, total X-ray absorbed dose was significantly higher in Group I (121 +/- 69 vs 29 +/- 16 mGy/cm2, p < 0.01). Immediate, 24 h, and mid-term (46 +/- 37 months, median 39) complete occlusion were recorded in 72.7, 90.9, and 97% of patients, respectively without significant difference between the groups. In conclusion, transcatheter closure of AD with Amplatzer Duct Occluder devices is feasible, safe, and effective also in infants less than 6 kg, without significant difference between the most commonly used devices, namely, ADO I and ADO II-AS. PMID- 29453686 TI - Antipsychotic Prescribing and Safety Monitoring Practices in Children and Youth: A Population-Based Study in Alberta, Canada. AB - BACKGROUND AND OBJECTIVE: Antipsychotic medication use has steadily increased in Canada, with an expansion in the profile of users and the diagnoses for which they are used. The use of antipsychotics is associated with a number of adverse effects for which routine monitoring is recommended. The objectives of this study were to determine the most common diagnoses associated with antipsychotic use in children in Alberta, Canada and the proportion who receive recommended laboratory tests for adverse effects. METHODS: Data on dispensed antipsychotics, diagnoses, prescribers, and laboratory testing were obtained from provincial data sources. To assess the frequency of metabolic and hormonal laboratory baseline and/or follow-up testing, the sample was divided into an antipsychotic-naive cohort and an antipsychotic non-naive cohort. RESULTS: In 2014, 6916 children were dispensed at least one second- or third-generation antipsychotic. The most frequently dispensed antipsychotics were risperidone (3908 children), quetiapine (2140 children), and aripiprazole (1302 children). The majority of children prescribed risperidone were diagnosed with Attention Deficit Hyperactivity Disorder (ADHD) or conduct disorder. Quetiapine was mainly prescribed for neurotic disorder or depression, while aripiprazole was prescribed most frequently for conduct disorder or neurotic disorders. Among antipsychotic-naive patients, 17% had at least one laboratory test done at baseline, and 35% had at least one laboratory test done at follow-up. In the non-naive patients, 42% had at least one follow-up laboratory test. Lipid and glucose testing were done in less than 5% of the naive cohort at baseline, and in less than 15% at follow-up. In the non-naive cohort, less than 22% received lipid or glucose testing during the year 2014. CONCLUSIONS: The majority of antipsychotic use in children in Alberta is off label and associated with disruptive behavior disorders, depression, and anxiety disorders. The vast majority of children prescribed antipsychotic medications do not undergo recommended laboratory tests. PMID- 29453687 TI - Impact of Boosted Antiretroviral Therapy on the Pharmacokinetics and Efficacy of Clopidogrel and Prasugrel Active Metabolites. AB - BACKGROUND AND OBJECTIVES: Prasugrel and clopidogrel are inhibitors of the ADP P2Y12 platelet receptor used in acute coronary syndrome patients. They require bioactivation via isoenzymes such as cytochrome P450 (CYP) 3A4, CYP2C19 and CYP2B6. Ritonavir and cobicistat are potent CYP3A inhibitors, prescribed as pharmacokinetic (PK) enhancers in the treatment of human immunodeficiency virus (HIV) infection. METHODS: In this study, the impact of boosted antiretroviral therapies (ARTs) on the PK of clopidogrel and prasugrel active metabolites (AMs), and on the efficacy of prasugrel and clopidogrel, were evaluated in a randomized crossover clinical trial. RESULTS: A significantly lower exposure to clopidogrel AM [3.2-fold lower area under the concentration-time curve (AUC) and maximum plasma concentration (Cmax)] and prasugrel AM (2.1-fold and 1.7-fold lower AUC and Cmax) were demonstrated in HIV-infected patients treated with boosted ARTs compared with healthy controls; however, a differential impact was observed on platelet inhibition between clopidogrel and prasugrel. Clopidogrel 300 mg induced adequate (although modest) platelet inhibition in all healthy subjects, while platelet inhibition was insufficient in 44% of HIV patients. On the contrary, prasugrel 60 mg induced a potent platelet inhibition in both healthy and HIV infected subjects. CONCLUSION: Prasugrel appears to remain an adequate antiplatelet agent in HIV-infected patients and could be preferred to clopidogrel in this context, regardless of the metabolic interaction and inhibition of its bioactivation pathways. PMID- 29453688 TI - Rapid optimization of spore production from Bacillus amyloliquefaciens in submerged cultures based on dipicolinic acid fluorimetry assay. AB - Some optimization techniques have been widely applied for spore fermentation based on the plate counting. This study optimized the culture medium for the spore production of Bacillus amyloliquefaciens BS-20 and investigated the feasibility of using a dipicolonic acid (DPA) fluorimetry assay as a simpler alternative to plate counting for evaluating spore yields. Through the single factor experiment, the metal ions and agro-industrial raw materials that significantly enhanced spore production were determined. After conducting a response surface methodology (RSM) analysis of several metal ions, the combined use of optimum concentrations of Mn2+, Fe2+, and Ca2+ in culture media produced a 3.4-fold increase in spore yields. Subsequently, supplementing soybean meal and corn meal with optimum concentrations determined by another RSM analysis produced an 8.8-fold increase. The final spore concentration from a culture medium incorporating optimum concentrations of the metal ions and raw materials mentioned above was verified to reach (8.05 +/- 0.70) * 109 CFU/mL by both DPA fluorimetry and plate counting. The results suggest that the use of DPA fluorescence intensity as an alternative value to colony counting provides a general method for assessing spore yields with less work and shorter time. PMID- 29453689 TI - Sustained sensorimotor control as intermittent decisions about prediction errors: computational framework and application to ground vehicle steering. AB - A conceptual and computational framework is proposed for modelling of human sensorimotor control and is exemplified for the sensorimotor task of steering a car. The framework emphasises control intermittency and extends on existing models by suggesting that the nervous system implements intermittent control using a combination of (1) motor primitives, (2) prediction of sensory outcomes of motor actions, and (3) evidence accumulation of prediction errors. It is shown that approximate but useful sensory predictions in the intermittent control context can be constructed without detailed forward models, as a superposition of simple prediction primitives, resembling neurobiologically observed corollary discharges. The proposed mathematical framework allows straightforward extension to intermittent behaviour from existing one-dimensional continuous models in the linear control and ecological psychology traditions. Empirical data from a driving simulator are used in model-fitting analyses to test some of the framework's main theoretical predictions: it is shown that human steering control, in routine lane-keeping and in a demanding near-limit task, is better described as a sequence of discrete stepwise control adjustments, than as continuous control. Results on the possible roles of sensory prediction in control adjustment amplitudes, and of evidence accumulation mechanisms in control onset timing, show trends that match the theoretical predictions; these warrant further investigation. The results for the accumulation-based model align with other recent literature, in a possibly converging case against the type of threshold mechanisms that are often assumed in existing models of intermittent control. PMID- 29453690 TI - The effectiveness of targeted relative to empiric prophylaxis on infectious complications after transrectal ultrasound-guided prostate biopsy: a meta analysis. AB - PURPOSE: Rectal culture screening for fluoroquinolone (FQ)-resistant Enterobacteriaceae before transrectal ultrasound guided prostate (TRUSPB) biopsy and targeted antibiotic prophylaxis (TAP) may decrease post-TRUSPB infection rates compared to empiric (EAP) regimens. The objective of this study was to evaluate the effectiveness of targeted relative to empiric prophylaxis regimens on rates of infectious complications after TRUSPB and to determine the baseline prevalence of FQ resistance based on prior rectal swabs. METHODS: An electronic search within literature databases including EMBASE and Web of Science (all databases) for articles assessing TAP as an approach to TRUSPB prophylaxis was conducted. Quality assessment was performed using the Hoy instrument. Meta analysis was performed using MetaXL 5.3. RESULTS: From 15 studies (eight retrospective and seven prospective) representing 12,320 participants, infectious complication incidence was 3.4% in EAP and 0.8% in TAP patients. The number needed to treat with TAP to avoid one more infection when compared to the EAP group was 39. Effect sizes were homogeneous. Prevalence of FQ resistance showed low (15%) and high (28%) subgroups, likely due to region of origin (within and outside USA, respectively). CONCLUSIONS: Rectal culture prior to TRUSPB and use of TAP adjusts for endemic FQ resistance and is associated with less infectious complications and resulting morbidity when compared to EAP. Overtreatment associated with augmented prophylaxis approaches may be reduced as a result. Further prospective assessment and cost-benefit analyses are required before widespread implementation can be recommended. PMID- 29453691 TI - Effect of phosphorylation and single nucleotide polymorphisms on caspase substrates processing. AB - Posttranslational modifications that involve either reversible covalent modification of proteins or irreversible proteolysis are central to the regulation of key cellular mechanisms, including apoptosis, cell-cycle regulation and signal transduction. There is mounting evidence suggesting cross-talk between proteases and kinases. For instance: caspases, a class of proteases involved in programmed cell death-apoptosis, cleave a large set of various types of proteins. Simultaneously, kinases restrict caspase activity by phosphorylating their protein substrates in the vicinity of cleavage site. In addition, the caspase cleavage pattern in target proteins may be modified as a result of single nucleotide polymorphisms (SNPs) in the coding gene. This may either create a novel cleavage site, or increase/decrease the cleavage efficiency of a substrate. Such point mutations are often associated with the onset of disease. In this study, we predicted how phosphorylation and SNPs affect known human caspase proteolytic events collected in the CASBAH and Degrabase databases by applying Random Forest caspases' substrates prediction method, as implemented in the CaspDB, and the molecular dynamics free energy simulations approach. Our analysis confirms several experimental observations. Phosphorylation could have both positive or negative regulatory effects depending on its position with respect to the caspase cleavage site. For instance, we demonstrate that phosphorylation at P1' is the most detrimental for proteolytic efficiency of caspases. Phosphorylation at the P2 and P2' positions also negatively affect the cleavage events. In addition, we uncovered SNPs in 11 caspase substrates capable of completely abolishing the cleavage site due to polymorphism at the P1 position. The findings presented here may be useful for determining the link between aberrant proteolysis and disease.

PMID- 29453693 TI - Exploiting the unique phenotypes of the earthworm Eudrilus eugeniae to evaluate the toxicity of chemical substances. AB - Both the evaluation and the determination of toxicity of chemical substances present in the environment have implications in human health. In this present study, the natural phenomenon named autotomy, a self-defense mechanism employed by several animals against the toxic chemical contaminants, was considered to assess the toxicity of different chemical substances. We investigated the effects of glucose, sodium chloride, kanamycin, mercuric chloride, arsenic trioxide, and lead oxide on the phenotypes of earthworm Eudrilus eugeniae. Depending on the concentration of different chemicals, worms exhibit unique phenotypes. These phenotypes can be used to identify the toxicity as well as the toxic concentration of the chemicals. Upon exposure to toxic chemicals, worms use different mechanical forces at the site of cleavage furrow to detach its segments. During the detachment, there is no apparent blood loss at both the ends of the worm. Our results show that the mercuric chloride is toxic at the concentration above 5 MUg when compared to other chemicals. Based on our findings, the toxic effects of a chemical and the toxic concentration of a chemical can be evaluated in both cost and time-efficient manner; in addition, these chemicals can be classified into the following categories: (1) mercuric chloride is extreme-toxic, (2) arsenic trioxide and lead oxide is toxic, (3) kanamycin and sodium chloride is low-toxic, and (4) glucose is non-toxic. PMID- 29453694 TI - Percutaneous left atrial appendage occlusion in the prevention of stroke in atrial fibrillation: a systematic review. AB - Atrial fibrillation is commonly coexistent with heart failure, and the management of the heart failure patient would be incomplete without an appreciation for atrial fibrillation management. There are many complications associated with oral anticoagulation in the prevention of stroke related to atrial fibrillation. In recent years, the advent of several percutaneous left atrial appendage (LAA) occlusion/closure strategies has sought to provide an alternative treatment modality. Here, we systematically review the published literature to investigate the efficacy and safety of percutaneous LAA occlusion/closure devices. We searched PubMed, EMBASE, Cochrane database of systematic reviews, and the FDA Medical Devices database. Using prespecified criteria, we identified studies of the Amplatzer Cardiac Plug (St. Jude Medical), Amplatzer Amulet (St. Jude Medical), Lariat suture delivery device (SentreHeart), and Watchman device (Boston Scientific). We analyzed 2 randomized controlled trials (RCT) and 15 non randomized registries that satisfied the study criteria. The two RCT both studied the Watchman device versus standard warfarin therapy; the studies indicate that the Watchman may be non-inferior to warfarin. Long-term efficacy outcomes for the Watchman device are promising. Data regarding the Amplatzer Cardiac Plug, Amplatzer Amulet, and Lariat suture delivery device are limited by the paucity of RCT data. High-quality prospective research is needed to directly compare LAA occlusion/closure strategies against one another as well as versus the direct oral anticoagulation medications. Data regarding the role of LAA occlusion in the heart failure population are lacking. PMID- 29453695 TI - Temporary assist device support for the right ventricle: pre-implant and post implant challenges. AB - Severe right ventricular (RV) failure is more likely reversible than similar magnitudes of left ventricular (LV) failure and, because reversal of both adaptive remodeling and impaired contractility require most often only short periods of support, the use of temporary RV assist devices (t-RVADs) can be a life-saving therapy option for many patients. Although increased experience with t-RVADs and progresses made in the development of safer devices with lower risk for complications has improved both recovery rate of RV function and patient survival, the mortality of t-RVAD recipients can still be high but it depends mainly on the primary cause of RV failure (RVF), the severity of end-organ dysfunction, and the timing of RVAD implantation, and much less on adverse events and complications related to RVAD implantation, support, or removal. Reduced survival of RVAD recipients should therefore not discourage appropriate application of RVADs because their underuse further reduces the chances for RV recovery and patient survival. The article reviews and discusses the challenges related to the pre-implant and post-implant decision-making processes aiming to get best possible therapeutic results. Special attention is focused on pre implant RV assessment and prediction of RV improvement during mechanical unloading, patient selection for t-RVAD therapy, assessment of unloading-promoted RV recovery, and prediction of its stability after RVAD removal. Particular consideration is also given to prediction of RVF after LVAD implantation which is usually hampered by the complex interactions between the different risk factors related indirectly or directly to the RV potential for reverse remodeling and functional recovery. PMID- 29453697 TI - The sacral autonomic outflow is parasympathetic: Langley got it right. AB - A recent developmental study of gene expression by Espinosa-Medina, Brunet and colleagues sparked controversy by asserting a revised nomenclature for divisions of the autonomic motor system. Should we re-classify the sacral autonomic outflow as sympathetic, as now suggested, or does it rightly belong to the parasympathetic system, as defined by Langley nearly 100 years ago? Arguments for rejecting Espinosa-Medina, Brunet et al.'s scheme subsequently appeared in e letters and brief reviews. A more recent commentary in this journal by Brunet and colleagues responded to these criticisms by labeling Langley's scheme as a historical myth perpetuated by ignorance. In reaction to this heated exchange, I now examine both sides to the controversy, together with purported errors by the pioneers in the field. I then explain, once more, why the sacral outflow should remain known as parasympathetic, and outline suggestions for future experimentation to advance the understanding of cellular identity in the autonomic motor system.

AB - Paracoccidioidomycosis is a common deep fungus infection in South America, particularly in Brazil. It is acquired through inhalation and primary involvement of lungs. Subsequently, dissemination may occur and oral mucosa is frequently affected and actually, in most of the cases the diagnosis is established because of the oral lesions. Thus, the role of the dentist is fundamental to correct diagnosis. However, the involvement of intestine is rarely reported. The current case describes a 36-year-old man who presented abdominal pain and intestinal constipation, being suspected and then confirmed as paracoccidioidomycosis after already be diagnosed with this disease by a dentist through oral manifestations. PMID- 29453698 TI - Corneal Collagen Cross-Linking for the Management of Mycotic Keratitis. AB - PURPOSE: To evaluate the efficiency of corneal collagen cross-linking (CXL) in addition to topical voriconazole in cases with mycotic keratitis. DESIGN: Retrospective case series in a tertiary university hospital. PARTICIPANTS: CXL was performed on 13 patients with mycotic keratitis who presented poor or no response to topical voriconazole treatment. METHODS: The clinical features, symptoms, treatment results and complications were recorded retrospectively. The corneal infection was graded according to the depth of infection into the stroma (from grade 1 to grade 3). The visual analogue scale was used to calculate the pain score before and 2 days after surgery. MAIN OUTCOME MEASURES: Grade of the corneal infection. RESULTS: Mean age of 13 patients (6 female and 7 male) was 42.4 +/- 17.7 years (20-74 years). Fungus was demonstrated in culture (eight patients) or cytological examination (five patients). Seven of the 13 patients (54%) were healed with topical voriconazole and CXL adjuvant treatment in 26 +/- 10 days (15-40 days). The remaining six patients did not respond to CXL treatment; they initially presented with higher grade ulcers. Pre- and post operative pain score values were 8 +/- 0.8 and 3.5 +/- 1, respectively (p < 0.05). CONCLUSIONS: The current study suggests that adjunctive CXL treatment is effective in patients with small and superficial mycotic ulcers. These observations require further research by large randomized clinical trials.

AB - The purpose of this study is to evaluate the reliability of cartilage digestion and fluorescein diacetate-ethidium bromide (FDA-EB) fluorescence staining for the detection of chondrocyte viability in osteochondral grafts. Sixteen fresh osteochondral grafts were harvested from pig knee condyles, and the articular cartilage tissue was preserved. Each cartilage graft was cut into two 70-um thick pieces and randomly allocated to Group A or Group B. The cell viability of Group A was detected using FDA-EB fluorescence staining of the digested cartilage, and the viability of Group B was detected with FDA-EB fluorescence staining of cartilage sections. Comparisons of chondrocyte viability and correlation analyses of the two groups were performed using the paired sample t test and Pearson correlation test, respectively. No significant difference was found in the chondrocyte viability between Groups A and B (p > 0.05), and a strong correlation was observed (r = 0.70, p < 0.05). Therefore, cartilage digestion with FDA-EB fluorescence staining is a reliable method for detecting chondrocyte viability in osteochondral grafts.

AB - Heart failure (HF) is a common cardiac syndrome, whose pathophysiology involves complex mechanisms, some of which remain unknown. Diabetes mellitus (DM) constitutes not only a glucose metabolic disorder accompanied by insulin resistance but also a risk factor for cardiovascular disease and HF. During the last years though emerging data set up, a bidirectional interrelationship between these two entities. In the case of DM impaired calcium homeostasis, free fatty acid metabolism, redox state, and advance glycation end products may accelerate cardiac dysfunction. On the other hand, when HF exists, hypoperfusion of the liver and pancreas, b-blocker and diuretic treatment, and autonomic nervous system dysfunction may cause impairment of glucose metabolism. These molecular pathways may be used as therapeutic targets for novel antidiabetic agents. Peroxisome proliferator-activated receptors (PPARs) not only improve insulin resistance and glucose and lipid metabolism but also manifest a diversity of actions directly or indirectly associated with systolic or diastolic performance of left ventricle and symptoms of HF. Interestingly, they may beneficially affect remodeling of the left ventricle, fibrosis, and diastolic performance but they may cause impaired water handing, sodium retention, and decompensation of HF which should be taken into consideration in the management of patients with DM. In this review article, we present the pathophysiological data linking HF with DM and we focus on the molecular mechanisms of PPARs agonists in left ventricle systolic and diastolic performance providing useful insights in the molecular mechanism of this class of metabolically active regiments.

AB - The skeleton is the most common metastatic site in patients with advanced cancer. Pain is a major healthcare problem in patients with bone metastases. Bone-seeking radionuclides that selectively accumulate in the bone are used to treat cancer induced bone pain and to prolong survival in selected groups of cancer patients. The goals of these guidelines are to assist nuclear medicine practitioners in: (a) evaluating patients who might be candidates for radionuclide treatment of bone metastases using beta-emitting radionuclides such as strontium-89 (89Sr), samarium-153 (153Sm) lexidronam (153Sm-EDTMP), and phosphorus-32 (32P) sodium phosphate; (b) performing the treatments; and PMID- 29453703 TI - Reply: Interim FDG-PET/CT in primary mediastinal diffuse large B-cell lymphoma: really almost useless procedure? PMID- 29453704 TI - Brief Report: Reliability of the Participation and Sensory Environment Questionnaire: Home Scales. AB - The Participation and Sensory Environment Questionnaire: Home Scales (P-SEQ): Home Scales is a parent report tool designed to assess the impact of the sensory environment on participation in daily activities in the home of children with and without autism spectrum disorder. A cross-sectional study was completed to determine internal consistency, test-retest reliability, and examine item distribution. A total of 304 parents of children between the ages of 2 and 7 years of age completed the P-SEQ: Home Scales. Results identified excellent internal consistency (alpha = 0.96), moderate test-retest reliability (r = .62), and reasonable item distribution. Results suggest that the P-SEQ: Home Scales provides reliable estimates of the impact of the sensory environment on children's participation in home activities. PMID- 29453702 TI - The relationship between local recurrences and distant metastases in prostate cancer: can 11C-choline PET/CT contribute to understand the link? AB - PURPOSE: Previous studies in prostate cancer (PCa) patients tried to correlate the onset of local recurrence (LR) with the development of distant metastases and formulated, based on theoretical and experimental data, hypotheses linking the two events. We aimed to address this issue with 11C-choline positron emission tomography/computed tomography (PET/CT). METHODS: This retrospective study included 491 PCa patients previously treated with radical prostatectomy who had undergone 11C-choline PET/CT owing to biochemical failure. Further inclusion criteria were availability of clinical and pathological variables for survival analysis. Statistical significance was taken at P < 0.05. RESULTS: Seventy-two patients (14.7%) had evidence of LR at 11C-choline PET/CT. The frequency of LR increased from 13.8% in the interval 0-4 years after prostatectomy, to 23.9% in the 12-16-year interval (P = 0.080). On the contrary, the frequency of lymph node metastases (overall rate in the 0-16 years interval after prostatectomy: 26.3%) and of bone metastases (overall rate: 13.8%) decreased significantly over time. Kaplan-Meier curves showed no significant group difference in the rates of lymph node or bone metastases between patients with LR and patients without LR. LR significantly predicted PCa-specific survival at univariate analysis, but the statistical significance was lost at multivariate analysis. CONCLUSION: We found no differences in the rates of lymph node and bone metastases between patients with and without LR. An inverse time-dependent trend was observed in the frequency of LR on one side and of lymph node and bone metastases on the other side. These findings were discussed in relation to previous theories linking LR to distant metastases and our study design.

AB - The purpose of this study was to examine the effects of a peer-mediated LEGO(r) play intervention on improving social skills for children with ASD in an inclusive preschool in China. Three boys with ASD and 13 typically developing children participated in this study. A multiple-probe across participants design was used. The intervention consisted of LEGO(r) construction activities incorporated with peer-mediated strategies for one child with ASD and two typically developing peers. The intervention sessions were conducted two sessions per week with a total of 28-31 sessions for each participant. Results indicated that all three children with ASD increased their social initiations and responses following the completion of the intervention. Social validity was also obtained. PMID- 29453706 TI - Family Experiences with the Diagnosis of Autism Spectrum Disorder: System Barriers and Facilitators of Efficient Diagnosis. AB - This paper examines family experiences with the efficiency of ASD diagnosis. Children were age 8 or younger with ASD (n = 450). Outcomes were delay from first parent concern to diagnosis, shifting diagnoses, and being told child did not have ASD. Predictors were screening, travel distance, and problems finding providers. Logit models were used to examine associations. Screening was associated with reduced delay in diagnosis; problems finding providers were associated with greater delay. Screening, travel distance, and delay in diagnosis were associated with shifting diagnoses and being told child did not have ASD. Physician and parent training in communication and addressing mental health professional shortages and maldistribution may improve the diagnosis experiences of families of children with ASD. PMID- 29453708 TI - Exploring the Effectiveness of a Peer-Mediated Model of the PEERS Curriculum: A Pilot Randomized Control Trial. AB - This study compared immediate and 4-month outcomes among adolescents with autism spectrum disorder randomly assigned to the PEERS curriculum (n = 10), a peer mediated PEERS curriculum (n = 12), or a delayed treatment control group (n = 12). Findings suggest a modest advantage in social skills knowledge and social functioning for participants in the peer-mediated PEERS curriculum relative to Traditional PEERS, and gains in social skills knowledge, social functioning, and reductions in loneliness were maintained in one or both treatment groups at a 4 month follow-up. Typically developing peer mentors (n = 16) showed improvements in social skills knowledge and marginal improvements in autism knowledge and loneliness. Future research with a larger sample and objective outcome measures is needed. PMID- 29453707 TI - Brief Report: When Large Becomes Slow: Zooming-Out Visual Attention Is Associated to Orienting Deficits in Autism. AB - Previous studies independently demonstrated impairments in rapid orienting/disengagement and zooming-out of spatial attention in autism spectrum disorder (ASD). These attentional mechanisms, however, are not completely independent. Aiming at a more complete picture of spatial attention deficits in ASD, we examined the relationship between orienting and zooming in participants with ASD and typically developing peers. We modified a classical spatial cuing task, presenting two small or large cues in the two visual hemifields and subsequently cueing attention to one of them. Our results demonstrate a sluggish orienting mechanism in ASD only when a large attentional focus is deployed. Moreover, only the sluggish orienting mechanism in the large cues condition predicts the severity in the social-interaction symptomatology in individuals with ASD. PMID- 29453709 TI - Prediction of Autism at 3 Years from Behavioural and Developmental Measures in High-Risk Infants: A Longitudinal Cross-Domain Classifier Analysis. AB - We integrated multiple behavioural and developmental measures from multiple time points using machine learning to improve early prediction of individual Autism Spectrum Disorder (ASD) outcome. We examined Mullen Scales of Early Learning, Vineland Adaptive Behavior Scales, and early ASD symptoms between 8 and 36 months in high-risk siblings (HR; n = 161) and low-risk controls (LR; n = 71). Longitudinally, LR and HR-Typical showed higher developmental level and functioning, and fewer ASD symptoms than HR-Atypical and HR-ASD. At 8 months, machine learning classified HR-ASD at chance level, and broader atypical development with 69.2% Area Under the Curve (AUC). At 14 months, ASD and broader atypical development were classified with approximately 71% AUC. Thus, prediction of ASD was only possible with moderate accuracy at 14 months.

PMID- 29453711 TI - Prevalence of DSM-5 Autism Spectrum Disorder Among School-Based Children Aged 3 12 Years in Shanghai, China. AB - We estimated the prevalence of ASD in a population-based sample comprising children aged 3-12 years (N = 74,252) in Shanghai. This included a high-risk group sampled from special education schools and a low-risk group randomly sampled from general schools. First, we asked parents and then teachers to complete the Social Communication Questionnaire for participating children. Children who screened positive based on both parental and teachers' reports were comprehensively assessed. ASD was identified based on DSM-5 criteria. We identified 711 children as being at-risk for ASD, of which 203 were identified as ASD cases. The prevalence of ASD was 8.3 per 10,000, which is likely an underestimate, given that 81.6% of the children diagnosed with ASD had IQs below 40. This is the first report on the prevalence of ASD according to DSM-5 in China. PMID- 29453710 TI - Investigating Mirror System (MS) Activity in Adults with ASD When Inferring Others' Intentions Using Both TMS and EEG. AB - ASD is associated with mentalizing deficits that may correspond with atypical mirror system (MS) activation. We investigated MS activity in adults with and without ASD when inferring others' intentions using TMS-induced motor evoked potentials (MEPs) and mu suppression measured by EEG. Autistic traits were measured for all participants. Our EEG data show, high levels of autistic traits predicted reduced right mu (8-10 Hz) suppression when mentalizing. Higher left mu (8-10 Hz) suppression was associated with superior mentalizing performances. Eye tracking and TMS data showed no differences associated with autistic traits. Our data suggest ASD is associated with reduced right MS activity when mentalizing, TMS-induced MEPs and mu suppression measure different aspects of MS functioning and the MS is directly involved in inferring intentions. PMID- 29453713 TI - 1H, 13C, and 15N resonance assignments of CW domain of the N-methyltransferase ASHH2 free and bound to the mono-, di- and tri-methylated histone H3 tail peptides. AB - The ASHH2 CW domain is responsible for recognizing the methylation state at lysine 4 of histone 3 N-terminal tails and implicated in the recruitment of the ASHH2 methyltransferase enzyme correctly to the histones. The ASHH2 CW domain binds H3 lysine motifs that can be either mono-, di-, or tri-methylated [ARTK(meX)QTAR, where X denotes the number of methylations], but binds strongest to monomethylated instances (Kd values reported in the range of 1 um to 500 nM). Hoppmann et al. published the uncomplexed NMR structure of an ASHH2 CW domain in 2011. Here we document the assignment of a shortened ASHH2 CW construct, CW42, with similar binding affinity and better expression yields than the one used to solve the uncomplexed structure. We also perform 1H-15N HSQC-monitored titrations that document at which protein-peptide ratios the complex is saturated. Backbone resonance assignments are presented for this shortened ASHH2 CW domain alone and bound to an H3 histone tail mimicking peptide monomethylated on lysine 4 (ARTK(me1)QTAR). Likewise, the assignment was also performed for the protein in complex with the dimethylated (ARTK(me2)QTAR) and trimethylated (ARTK(me3)QTAR) peptide. Overall, these two latter situations displayed a similar perturbation of shifts as the mono-methylated instance. In the case of the monomethylated histone tail mimic, side-chain assignment of CW42 in this complex was performed and reported in addition to backbone assignment, in preparation of a future solution structure determination and dynamics characterization of the CW42-ARTK(me1)QTAR complex. PMID- 29453714 TI - Backbone 1H, 13C, and 15N assignments of the extracellular region of human Fcgamma receptor IIIb. AB - Fcgamma receptor (FcgammaR) promotes various immune responses through interactions with the Fc portion of immunoglobulin G (IgG). FcgammaRIIIb is a glycosylphosphatidylinositol-linked protein expressed on neutrophils and triggers degranulation and opsonic phagocytosis. The extracellular region of FcgammaR is composed of two Ig-fold domains and can be cleaved as a soluble form (sFcgammaRIIIb), which is also reactive with complement receptor type 3. Although structure and Fc interaction of sFcgammaRIIIb have been characterized by X-ray crystallography, little has been known about its structure in solution. We herein report the backbone NMR assignments of human sFcgammaRIIIb to gain basic understanding of functional IgG-FcgammaRIII interactions of immunological and biopharmaceutical interest regarding the structural investigation. PMID- 29453715 TI - The influence of heavy metals, polyaromatic hydrocarbons, and polychlorinated biphenyls pollution on the development of antibiotic resistance in soils. AB - The minireview is devoted to the analysis of the influence of soil pollution with heavy metals, polyaromatic hydrocarbons (PAHs), and the polychlorinated biphenyls (PCBs) on the distribution of antibiotics resistance genes (ARGs) in soil microbiomes. It is shown that the best understanding of ARGs distribution process requires studying the influence of pollutants on this process in natural microbiocenoses. Heavy metals promote co-selection of genes determining resistance to them together with ARGs in the same mobile elements of a bacterial genome, but the majority of studies focus on agricultural soils enriched with ARGs originating from manure. Studying nonagricultural soils would clear mechanisms of ARGs transfer in natural and anthropogenically transformed environments and highlight the role of antibiotic-producing bacteria. PAHs make a considerable shift in soil microbiomes leading to an increase in the number of Actinobacteria which are the source of antibiotics formation and bear multiple ARGs. The soils polluted with PAHs can be a selective medium for bacteria resistant to antibiotics, and the level of ARGs expression is much higher. PCBs are accumulated in soils and significantly alter the specific structure of soil microbiocenoses. In such soils, representatives of the genera Acinetobacter, Pseudomonas, and Alcanivorax dominate, and the ability to degrade PCBs is connected to horizontal gene transfer (HGT) and high level of genomic plasticity. The attention is also focused on the need to study the properties of the soil having an impact on the bioavailability of pollutants and, as a result, on resistome of soil microorganisms. PMID- 29453717 TI - U-tube based near-surface environmental monitoring in the Shenhua carbon dioxide capture and storage (CCS) project. AB - The CO2 injected into deep formations during implementation of carbon dioxide (CO2) capture and storage (CCS) technology may leak and migrate into shallow aquifers or ground surfaces through a variety of pathways over a long period. The leaked CO2 can threaten shallow environments as well as human health. Therefore, almost all monitoring programs for CCS projects around the world contain near surface monitoring. This paper presents a U-tube based near-surface monitoring technology focusing on its first application in the Shenhua CCS demonstration project, located in the Ordos Basin, Inner Mongolia, China. First, background information on the site monitoring program of the Shenhua CCS demonstration project was provided. Then, the principle of fluid sampling and the monitoring methods were summarized for the U-tube sampler system, and the monitoring data were analyzed in detail. The U-tube based monitoring results showed that the U tube sampler system is accurate, flexible, and representative of the subsurface fluid sampling process. The monitoring indicators for the subsurface water and soil gas at the Shenhua CCS site indicate good stratification characteristics. The concentration level of each monitoring indicator decreases with increasing depth. Finally, the significance of this near-surface environmental monitoring technology for CO2 leakage assessments was preliminarily confirmed at the Shenhua CCS site. The application potential of the U-tube based monitoring technology was also demonstrated during the subsurface environmental monitoring of other CCS projects.

AB - This study presents computational fluid dynamics (CFD) simulation of dispersion free liquid-liquid extraction of copper(II) with trifluoroacetylacetone (TFA) in hollow fiber membrane contactor (HFMC). Mass and momentum balance Navier-Stokes equations were coupled to address the transport of copper(II) solute across membrane contactor. Model equations were simulated using COMSOL MultiphysicsTM. The simulation was run to study the detailed concentration distribution of copper(II) and to investigate the effects of various parameters like membrane characteristics, partition coefficient, and flow configuration on extraction efficiency. Once-through extraction was found to be increased from 10 to 100% when partition coefficient was raised from 1 to 10. Similarly, the extraction efficiency was almost doubled when porosity to tortuosity ratio of membrane was increased from 0.05 to 0.81. Furthermore, the study revealed that CFD can be used as an effective optimization tool for the development of economical membrane based dispersion-free extraction processes. PMID- 29453716 TI - Occurrence and assessment of the risk of ultraviolet filters and light stabilizers in Victorian estuaries. AB - This reconnaissance study was undertaken to examine the occurrence of common ultraviolet filters (UVF) and light stabilizers (UVLS), and preservatives in four different estuaries in Port Philip Bay, Victoria, for the first time. In total, 11 UV filters, 10 UV stabilizers, 12 preservatives and a metabolite, and one fragrance were screened in grab samples of water and sediment using a combination of solid phase extraction and gas and liquid chromatography mass spectrometry measurement techniques. In that context, 16 of the UVF and UVLS and 5 of the preservatives screened were observed in water and/or sediment samples. There are no marine water quality guideline values for any of the fragrances, preservatives and UV filters and light stabilizers in Australia's current national water quality guidelines, so potential risk was assessed using the risk quotient (RQ) and toxic unit (TU) concepts. In that context, only two chemicals (OC and EHMC) had both an RQ above 1 and a log10TU above - 3, suggesting that few of the screened chemicals would have posed an individual, short-term risk to organisms in the waters studied at the time of sampling. However, the detection of common UV filters, such as 4MBC, EHMC, OC and the common preservatives 2-PE, MP, and PB in these Victorian estuaries highlights that the existence of personal care products in the environment is not just an issue for more densley populated countries in the northern hemisphere, but also potentially of concern in Australia. And, in that context, more sampling campaigns in Port Philip Bay are of paramount importance to assess the potential risk posed by these compounds to aquatic ecosystems. PMID- 29453719 TI - MicroRNA-411 promoted the osteosarcoma progression by suppressing MTSS1 expression. AB - MicroRNAs (miRNAs) play crucial roles in the progression of different tumors. In our study, we investigated the expression and roles of miR-411 in human osteosarcoma. In this study, we first confirmed that the miR-411 expression was higher in the serum of patients with osteosarcoma than in the serum of healthy volunteers. In addition, we found that the miR-411 expression was upregulated in the osteosarcoma tissues compared to that in the matched normal bone tissues. We also demonstrated that the miR-411 expression was upregulated in the four osteosarcoma cell lines. Elevated expression of miR-411 promoted osteosarcoma cell proliferation and migration. Moreover, we identified that metastasis suppressor protein 1 (MTSS1) was a direct target gene of miR-411 in the osteosarcoma cell. We also demonstrated that the MTSS1 expression was downregulated in the osteosarcoma tissues compared to that in the matched normal bone tissues. In addition, MTSS1 expression level was inversely correlated with miR-411 expression in the osteosarcoma tissues. Furthermore, elevated expression of miR-411 enhanced the osteosarcoma cell proliferation and migration through inhibiting the MTSS1 expression. These data suggested that miR-411 played as oncogene in the osteosarcoma partly by inhibiting the MTSS1 expression. PMID- 29453720 TI - Cytotoxic effect of chlorpyrifos is associated with activation of Nrf-2/HO-1 system and inflammatory response in tongue of male Wistar rats. AB - Repeated administration of chlorpyrifos (CPF), an organophosphate pesticide, can increase the risk of oral cytotoxicity. The current study was designed to assess the mechanism by which CPF mediates its cytotoxic effect on lingual mucosa of rats. Twenty-four male Wistar rats were used in the present study and divided into three groups: group I: healthy rats (negative control), group II: rats treated with CPF 1/40 LD50 (3.375 mg/kg, orally/daily) for 28 days, group III: rats treated with CPF 1/10 LD50 (13.5 mg/kg, orally/daily) for 28 days. At the end of the experiment, all rats were sacrificed by cervical dislocation under ketamine anesthesia. Tongue samples were dissected out at their base for detection of heme oxygenase-1 (HO-1) and nuclear erythroid 2-related factor 2 (Nrf-2) by western blotting and histopathological and electron microscopic studies. Immunostaining was used to determine cleaved caspase 3 and the nuclear factor kappa B (NF-kappaB) localization. Structural and ultrastructural examination of treated lingual mucosa with CPF demonstrated degenerative changes that involved both the dorsal and ventral surfaces of the tongue as well as the lingual glands. CPF-treated rats demonstrated a significant increase in the levels of pro-inflammatory cytokines such as interleukin-1beta (IL-1beta) and tumor necrosis factor (TNF-alpha) in addition to a significant dose-dependent activation of NF-kappaB and cleaved caspase 3. Furthermore, CPF activated HO-1 and Nrf-2 pathway in a dose-dependent manner. In conclusion, this data suggests that the CPF-induced cytotoxicity may be explained by NF-kappaB activated inflammatory cascade. In addition, CPF triggers an adaptive activation of Nrf 2/HO-1 pathway. PMID- 29453722 TI - ESPR special issue on Asian environmental chemistry. PMID- 29453721 TI - Fenton treatment of bio-treated fermentation-based pharmaceutical wastewater: removal and conversion of organic pollutants as well as estimation of operational costs. AB - The Fenton process is used as a tertiary treatment to remove organic pollutants from the effluent of bio-treated pharmaceutical wastewater (EBPW). The optimal and most appropriate Fenton conditions were determined by an orthogonal array test and single-factor experiments. The removal of chemical oxygen demand (COD) was influenced by the following factors in a descending order: H2O2/Fe(II) molar ratio > H2O2 dosage > reaction time. Under the most appropriate Fenton conditions (H2O2/Fe(II) molar ratio of 1:1, H2O2 dosage of 120 mg L-1 and reaction time of 10 min), the COD and dissolved organic carbon (DOC) were removed with efficiencies of 62 and 53%, respectively, which met the national discharge standard (GB 21903-2008) for the Lake Tai Basin, China. However, the Fenton treatment was inadequate for removal of N compounds, and the removal of organic nitrogen led to an increment in N-NH3 from 3.28 to 19.71 mg L-1. Proteins and polysaccharides were completely removed, and humic acids (HAs) were partly removed with an efficiency of 55%. Three-dimensional excitation/emission matrix spectra (3DEEMs) indicated complete removal of fulvic acid-like substances and 90% reduction in the florescence intensity of humic acid-like substances. Organic pollutants with molecular weights (MW) > 10 kDa were completely removed, MW 5-10 kDa were degraded into smaller MW ones, and some low molecular weight acids (MW 0.1-1 kDa) were mineralized during the Fenton process. Some species, including pharmaceutical intermediates and solvents were detected by gas chromatography mass spectrometry (GC-MS). The operational costs of the Fenton's treatment were estimated to be 0.58 yuan RMB/m3 EBPW based on reagent usage and iron sludge treatment and disposal. PMID- 29453723 TI - Macroelements and heavy metals content in energy crops cultivated on contaminated soil under different fertilization-case studies on autumn harvest. AB - Heavy metals (HMs) contamination of soils is a major problem occurring worldwide. Utility of energy crops for biofuel feedstock production systems offers a feasible solution for a commercial exploitation of an arable land contaminated with HMs. Experiments involved field testing of Miscanthus x giganteus and Spartina pectinata cultivated on HMs-contaminated soil with standard NPK fertilizers and commercially available microbial inoculum. Biomass yield, water content, macronutrients (N, P, K, Mg, Ca), and heavy metal (Cd, Pb, Zn) concentrations in plant shoots were assessed at the end of the first and the second growing season. Independently of the applied fertilizers, Miscanthus x giganteus produced higher biomass yield while contrary results were obtained for S. pectinata. Higher HMs content in plants influenced the status of the mineral macronutrients in particular N and K. Occurrence of hasted senescence induced by drought in the second growing season caused reduction in the concentrations of all elements (except Pb), due to earlier rhizomes relocation. PMID- 29453724 TI - Using combined multiple techniques to characterize refractory organics during anammox process with mature coal chemical wastewater as influent. AB - This study combined spectroscopy techniques to assess the composition of refractory organics and highlighted the potential application of excitation emission matrix (EEM) fluorescence spectroscopy within future monitoring of coal chemical wastewater treatment by the anammox process. The results showed that the anammox process could effectively degrade refractory organic substances, with fulvic-like, UV-humic acid, and Vis-humic acid component removal efficiencies of 43.61, 53.93, and 100%, respectively. In this study, EEM fluorescence spectroscopy was proven to be an effective method of assessing the removal of dissolved organic nitrogen during anammox treatment of mature coal chemical wastewater. Furthermore, remarkable accumulation (9.3-16.2%) of Ca. Kuenenia occurred in the anammox granules that underwent long-term cultivation in mature coal chemical wastewater, which provided the high nitrogen removal rate. The abundance of Anaerolineaceae and Bacteroides was vital in refractory organic degradation. PMID- 29453725 TI - Distribution and removal of organochlorine pesticides in waste clay bricks from an abandoned manufacturing plant using low-temperature thermal desorption technology. AB - The distribution of pollutants in waste clay bricks from an organochlorine pesticide-contaminated site was investigated, and removal of the pollutants using a thermal desorption technology was studied. The results showed that the contents of HCHs in both the surface and the inner layer of the bricks were slightly higher than those of DDTs. The total pore volume of the bricks was 37.7 to 41.6% with an increase from external to internal surfaces. The removal efficiency by thermal treatment was within 62 to 83% for HCHs and DDTs in bricks when the temperature was raised from 200 to 250 degrees C after 1 h. HCHs were more easily removed than DDTs with a higher temperature. Either intraparticle or surface diffusion controls the desorption processes of pollutants in bricks. It was feasible to use the polluted bricks after removal of the pollutants by low temperature thermal desorption technology. PMID- 29453726 TI - Advances in Probiotic Regulation of Bone and Mineral Metabolism. AB - Probiotics have been consumed by humans for thousands of years because they are beneficial for long-term storage of foods and promote the health of their host. Ingested probiotics reside in the gastrointestinal tract where they have many effects including modifying the microbiota composition, intestinal barrier function, and the immune system which result in systemic benefits to the host, including bone health. Probiotics benefit bone growth, density, and structure under conditions of dysbiosis, intestinal permeability, and inflammation (recognized mediators of bone loss and osteoporosis). It is likely that multiple mechanisms are involved in mediating probiotic signals from the gut to the bone. Studies indicate a role for the microbiota (composition and activity), intestinal barrier function, and immune cells in the signaling process. These mechanisms are not mutually exclusive, but rather, may synergize to provide benefits to the skeletal system of the host and serve as a starting point for investigation. Given that probiotics hold great promise for supporting bone health and are generally regarded as safe, future studies identifying mechanisms are warranted.

METHODS: Nine highly myopic eyes with MH of nine consecutive patients who underwent PPV were retrospectively evaluated. Three eyes were accompanied by retinal detachment (RD). ILM peeling was performed around the MH and some part of the ILM flap was left attached to the edge of the MH. Further manipulation of the ILM flap to cover the MH was not performed. Fluid-gas exchange was performed to the retinal vessel arcade level. Patients maintained a face down position for 3 to 7 days postoperatively. RESULTS: Complete MH closure was confirmed using optical coherence tomography in all eyes and three eyes with RD showed reattachment of the retina after the initial surgery. Visual acuity significantly improved (P = 0.02) and no eyes experienced MH reopening or RD occurrence during the follow-up period of 8.33 +/- 3.61 months after the surgery. CONCLUSIONS: MH with or without RD in highly myopic eyes could be successfully treated with PPV leaving ILM flap floating in vitreous fluid at the edge of the MH. After the ILM peeling, further manipulation of the ILM flap to cover the MH would not be necessary for the treatment of MH in high myopia. PMID- 29453728 TI - Single-site port robotic-assisted hysterectomy: an update. AB - Single-incision approach in robotic gynecology is a relatively new concept. The role of single-port systems in robotic hysterectomy, their advantages and disadvantages, as well as the technical challenges, are still under investigation. A systematic review was performed by searching in PubMed and Scopus databases. In 810 out of 1225 patients, hysterectomy was performed for non neoplastic disease. Single-Site(r) was the most common port system. Duration of the procedure and relative blood loss ranged from 60 to 311 min and 7 to 750 ml, respectively. The weight of the removed uteri ranged from 39 to 520 g. 4.9% of the included patients presented complications, among which bleeding, vaginal haematoma, laceration and dehiscence, umbilical hernia, and visceral injuries. Conversion rate to laparotomy reached 2.8%. Although some technical difficulties are still described in the literature, the single-port approach is becoming more standardized nowadays and performed by more surgeons. The initial phase of the learning curve can be achieved after five cases, while a proficiency in intracorporeal cuff suturing after 14 cases. Uterus weight and previous abdominal surgical history can still be limitations of the technique. Compared to our previous study, we can see that the technique has been used in more elderly or obese patients. The complication rate can reach 4.9% while the conversion rate can reach 2.8%. However, we consider that complication and conversion rates as well as surgical time could be improved with experience. Regarding post-operative pain and cosmetic outcomes, the lack of information do not allow us to draw any safe conclusions. PMID- 29453729 TI - Perioperative outcomes of robotic hysterectomy with mini-laparotomy versus open hysterectomy for uterus weighing more than 250 g. AB - To compare perioperative outcomes in patients undergoing robotic hysterectomy and extraction of specimen via mini-laparotomy (RHML) versus open hysterectomy (OH) when uterus weighs more than 250 g. To study the factors determining the length of hospital stay in 2 groups. A retrospective analysis of all hysterectomies performed for uterus weighing more than 250 g from the year 2012 to 2015 was conducted. A total of 140 patients were divided into 2 groups based on the type of surgery; RHML (n = 82) and OH (n = 58). Mini-laparotomy consisted of a customised incision connecting 2 left lateral port sites for specimen extraction after completing the hysterectomy robotically. Patient factors and perioperative outcomes were compared using Student's t tests and Chi-square analysis. Mean length of stay (RHML = 1.4 days; OH = 3.4 days), estimated blood loss (EBL) (RHML = 119.9 ml; OH = 547.5 ml) and operative time (RHML = 191.5 min; OH = 162.8 min) were significantly different. No significant differences were noted for patient BMI, age, comorbidities, intraoperative complications, pathology of uterus and uterus weight. Postoperative complications were significantly different between two groups (RHML = 6.0%; OH = 15.5%; p = .021). None of the patients stayed less than 24 h in OH group compared to 59.8% patients in RHML group. Type of procedure (p = .004) and EBL (p = .002) significantly predicted the length of stay. Patients undergoing RHML have significantly shorter length of stay, EBL and postoperative complications than OH. The operative time for RHML was longer than OH, but the overall decreased length of stay overcomes this disadvantage. RHML approach retains the benefits of da Vinci, while simultaneously preserving the specimen. PMID- 29453730 TI - Robotic-assisted bladder diverticulectomy: point of technique to identify the diverticulum. AB - We aim to outline our technique of performing a robotic-assisted bladder diverticulectomy at our institution and report our surgical outcomes. We report the cases of three robotic-assisted bladder diverticulectomies, performed at the Royal Surrey County Hospital during the period of January 2014 to December 2015. Patient was positioned in low dorsal lithotomy position. A 6Fr double-J stent was prophylactically inserted at the start of the procedure. Foley catheter was placed over guide wire into the diverticulum and balloon inflated on the diverticulum neck. We used a transperitoneal extravesical approach to mobilise the distended bladder diverticulum, dissected en bloc and transected at the diverticulum neck in all cases. The bladder was closed in two layers with absorbable sutures. The procedures were uneventful, without post-operative complications and minimal blood loss. The median length of stay was 3 days and all three patients reported a significant improvement in all symptoms with non significant post-void residuals. Robotic-assisted bladder diverticulectomy is a safe and effective procedure that results in both symptom relief and minimal post void residuals. PMID- 29453731 TI - Patient perceptions of acute pain and activity disruption following inguinal hernia repair: a propensity-matched comparison of robotic-assisted, laparoscopic, and open approaches. AB - Few publications describe the potential benefit of robotic-assisted inguinal hernia repair on acute postoperative groin pain (APGP). This study compared patients' perceptions of APGP, activity limitation, and overall satisfaction after robotic-assisted- (R), laparoscopic (L), or open (O) inguinal hernia repair (IHR). Random samples of patients from two web-based research panels and surgical practices were screened for patients who underwent IHR between October 28, 2015 and November 1, 2016. Qualified patients were surveyed to assess perceived APGP at 1 week postoperatively, activity disruption, and overall satisfaction. Three cohorts based on operative approach were compared after propensity matching. Propensity scoring resulted in 83 R-IHR matched to 83 L-IHR respondents, while 85 R-IHR matched with 85 O-IHR respondents. R-IHR respondents recalled less APGP compared to respondents who had O-IHR (4.1 +/- 0.3 vs 5.6 +/- 0.3, p < 0.01) but similar APGP compared to L-IHR (4.0 +/- 0.3 vs 4.4 +/- 0.3, p = 0.37). Respondents recalled less activity disruption 1 week postoperatively after R-IHR versus O-IHR (6.1 +/- 0.3 vs. 7.3 +/- 0.2, p < 0.01) but similar levels of activity disruption after R-IHR and L-IHR (6.0 +/- 0.3 vs. 6.6 +/- 0.27, p = 0.32). At the time of the survey, respondents perceived less physical activity disruption after R-IHR compared to O-IHR (1.4 +/- 0.2 vs. 2.8 +/- 0.4, p < 0.01) but similar between R-IHR and L-IHR (1.3 +/- 0.2 vs 1.2 +/- 0.2, p = 0.94). Most respondents felt satisfied with their outcome regardless of operative approach. Patient perceptions of pain and activity disruption differ by approach, suggesting a potential advantage of a minimally invasive technique over open for IHR. Further studies are warranted to determine long-term outcomes regarding pain and quality of life after IHR. PMID- 29453732 TI - The influence of postgraduate qualifications on educational identity formation of healthcare professionals. AB - Demand for postgraduate qualifications in medical education can be judged by the increase in providers worldwide over the last two decades. However, research into the impact of such courses on identity formation of healthcare professionals is limited. This study investigates the influence of such programmes on graduates' educational identities, practices and career progression. Informed by constructivist grounded theory (CGT), semi-structured interviews were conducted with 27 graduates (2008-2012) from one postgraduate programme, who were at different stages in their careers worldwide. The audio data were transcribed and analysed using a CGT approach. Participants enrolled in award-bearing medical education courses for various intrinsic and extrinsic reasons. The findings from this study highlight their development as educators, and educational researchers, leaders and learners, as their self-efficacy in educational practices and engagement in scholarly activities increased. Graduates attributed career progression to the qualification, with many being promoted into senior positions. They also described substantial performance attainments in the workplace. The findings contribute to understanding the complexity and nuances of educational identity formation of healthcare professionals. A qualification in medical education encouraged transformational changes and epistemological development as an educator. Awareness of these findings will inform both those considering enrolment and those supporting them of potential benefits of these programmes. PMID- 29453734 TI - Post-operative imaging assessment of non-functioning pituitary adenomas. AB - BACKGROUND: Non-functioning pituitary adenomas (NFAs) are the most common pituitary tumors. There is significant variability in clinical practice in terms of post-operative imaging evaluation. The objective of this manuscript is to provide an exhaustive review of published articles pertaining to the post operative imaging evaluation of NFAs. METHODS: The MEDLINE database was queried for studies investigating imaging for the post-operative evaluation of pituitary adenomas. From an initial search of 5589 articles, 37 articles were evaluated in detail and included in this review. RESULTS: Magnetic resonance imaging (MRI) is the gold standard for post-operative monitoring of NFAs, although functional imaging modalities may improve identification of residual tumor in conjunction with MRI. The residual tumor can be distinguished from post-operative changes by experienced practitioners using high-resolution MRI in the immediate post operative setting (within 1 week of surgery). However, continued imaging evolution in the appearance of residual tumor or resection cavity is expected up to 3 months post-operatively. CONCLUSIONS: Post-operative imaging appearance of the pituitary gland, optic apparatus, and pneumocephalus patterns, correlated with the clinical outcomes. Long-term, lifetime follow-up is warranted for NFA patients who underwent surgical resection. PMID- 29453733 TI - EGFP transgene: a useful tool to track transplanted bone marrow mononuclear cell contribution to peripheral remyelination. AB - Bone marrow mononuclear cells (BMMC) constitute a heterogeneous population with potential to promote tissue regeneration. For this reason, this cell fraction has recently become a therapeutic alternative to mesenchymal stem cells, as culture is not required and phenotypic transformations can be hence avoided. In this work, and in order to attain long-lasting cell labeling and study longer survival times, we used BMMC isolated from adult transgenic rats expressing GFP to reproduce our wild type model and evaluate their remyelination ability in a reversible model of Wallerian degeneration. RT-PCR and flow cytometry analysis confirmed that cells isolated from the transgenic strain exhibited similar expression levels of markers specific to multipotent progenitors (CD34, CD90 and CD105) and Schwann cells (MPZ, MBP, S100beta and p75NTR) compared to wild type BMMC. BMMC expressing GFP retained their migration capacity, arriving exclusively at the injured nerve. Most importantly, and as detected through long-lasting cell tracking, some of these BMMC settled in the demyelinated area, mingled with endogenous cells, underwent phenotypic changes and colocalized with Schwann cell markers MBP and S100beta. Also worth highlighting, transgenic BMMC replicated wild type BMMC effects in terms of MBP organization and levels. On the basis of these findings, BMMC isolated from transgenic animals constitute a useful tool to evaluate their role in peripheral nervous system demyelination-remyelination and the underlying mechanisms. PMID- 29453735 TI - Predictors of antegrade flow at internal carotid artery during carotid artery stenting with proximal protection. AB - BACKGROUND: Carotid artery stenting (CAS) with proximal occlusion effectively prevent distal cerebral embolism by flow arrest at internal carotid artery (ICA); however, the method can expose antegrade flow at ICA due to incomplete flow arrest. The aim of this study was to identify predictors of antegrade flow during CAS with proximal protection. METHODS: We retrospectively analyzed clinical and angiographic data among 143 lesions treated with CAS with proximal protection by occluding the common carotid artery (CCA) and external carotid artery (ECA). Flow arrest or antegrade flow at ICA was confirmed by contrast injection during proximal protection. RESULTS: Antegrade flow at ICA was observed in 12 lesions (8.4%). Compared with lesions in which flow arrest of ICA was achieved, the diameter of the superior thyroid artery (STA) was significantly larger (2.4 +/- 0.34 vs. 1.4 +/- 0.68 mm, p < 0.001), and the rate of ECA branches other than the STA located 0-10 mm above the bifurcation was significantly higher (50 vs. 8.4%, p < 0.001). Results of multivariate analysis revealed that a diameter of the STA >= 2.3 mm (OR 44, 95% CI 8.1-237; p < 0.001) and ECA branches other than the STA located 0-10 mm above the bifurcation (OR 6.0, 95% CI 1.1-32; p = 0.036) were independent predictors of antegrade flow. CONCLUSIONS: Distal filter protection should be combined with proximal protection for the lesions with antegrade flow to prevent distal migration of the carotid debris. PMID- 29453736 TI - Reproductive epidemiology of glial tumors may reveal novel treatments: high-dose progestins or progesterone antagonists as endocrino-immune modifiers against glioma. AB - Female gender, contraceptives, and menopausal hormone replacement treatments containing progesterone analogues associate with higher risk of meningiomas yet with lower risk of gliomas. Progesterone receptor (PR) expression and mifepristone treatment was highly discussed for meningiomas. However, much less is known in regard to progesterone actions in gliomas despite PR expression strongly correlates with their grade. Meningiomas and gliomas may grow faster during gestation; but paradoxically, parousity reduces lifetime risk of gliomas which can be explained with dichotomous cell growth-stimulating and inhibitory actions of progesterone at low versus high levels. Progesterone levels gradually increase in gestation up to 200-fold and the incidence of highly angiogenic brain tumors decreases in the last trimester. Indeed, progesterone stimulates glial tumor cell growth at low doses (10 nM) while induces cell kill at higher doses. During gestation, some immune pathways are activated to protect the mother and the fetus against microbial pathogens. In parallel, high-dose medroxyprogesterone acetate (MPA) used in treatment of endometrial carcinoma decreases tumoral expression of PR-B and increases infiltration of cytotoxic T lymphocytes and natural killer cells. MPA also synergies with IL-2 in clinical treatment of renal cancer. In both glioma and meningioma, the dominant cytosolic PR is PR-B which increases cell growth, while PR-A limits cell growth. This seems also paradoxical at the first glance due to opposite behavior of these tumors in diverse endocrine conditions. High-dose progestins may inhibit brain tumor growth by downregulating PR-B, yet the dosage thresholds may differ between glial and meningeal tumors due to higher total PR expression in meningiomas. Supporting this proposal, certain progestins were reported to stimulate meningioma growth in anecdotal reports, but same agents at much higher doses reduced meningioma cell proliferation in pilot clinical studies. PR antagonist mifepristone reduced meningioma growth in some clinical studies, but lacked efficacy in others. In fact, mifepristone also has partial PR agonist efficacy and acts in synergy with MPA to block EC growth. Hence, a similar mechanism of receptor downregulation may also account for mifepristone. Both MPA and mifepristone also harbor myeloprotective features against chemotherapy. Ulipristal is another contraceptive PR antagonist and exerts promising anticancer activity on drug-resistant ovarian cancer and BRCA1 mutant breast cancer cells, which can be tested in animal glioblastoma models. We propose that progestins strongly deserve to be investigated in experimental models of glioblastoma alone and in combination with immunostimulating agents. PMID- 29453737 TI - Two-stage hepatectomy aiming for the development of intrahepatic venous collaterals for multiple colorectal liver metastases. AB - BACKGROUND: Aggressive hepatectomy with venous resection has a higher risk of postoperative liver failure (POLF) than hepatectomy without venous reconstruction; however, venous reconstruction is technically demanding. We performed a novel two-stage hepatectomy (TSH) without venous reconstruction in a patient with bilobar multiple colorectal liver metastases located near the caval confluence, waiting for the development of intrahepatic venous collaterals between procedures. CASE PRESENTATION: A 60-year-old man was referred to our hospital with sigmoid colon cancer accompanied by intraabdominal abscess and two synchronous liver metastases. One of the liver tumors (tumor 1) was located in segment 8 near the caval confluence and was attached to both the right hepatic vein (RHV) and middle hepatic vein (MHV). The other tumor (tumor 2) in the left lobe invaded the umbilical portion of the portal vein. Both liver metastases decreased in size after four cycles of panitumumab/5-fluorouracil, leucovorin, and oxaliplatin (FOLFOX) therapy. Radical liver resection was planned because tumor 1 had not invaded the MHV. However, three-dimensional volumetric software showed that the non-congested volume of the future liver remnant was estimated at 354 ml, which corresponded to 26.3% of the total liver volume. TSH was scheduled to avoid POLF. We first performed limited resection of segment 8 with resection of the RHV root. After the first hepatectomy, the development of intrahepatic venous collaterals between the RHV and MHV was seen on computed tomography and magnetic resonance imaging. The estimated non-congested future liver remnant was 1242 ml, 78.5% of the total liver volume. Therefore, the patient underwent left hemihepatectomy 58 days after the first hepatectomy. We saw no adhesions around the porta hepatis, and the left hepatic artery and left branch of the portal vein were safely exposed and divided. Intraoperative Doppler ultrasonography revealed intrahepatic venous collaterals arising from RHV to MHV. The patient's postoperative course was uneventful, and he underwent eight cycles of panitumumab/FOLFOX therapy for 5 months after the second hepatectomy. CONCLUSIONS: Our TSH strategy helped avoid POLF by waiting for the development of intrahepatic venous collaterals. PMID- 29453738 TI - Friends in Activities, School-related Affect, and Academic Outcomes in Diverse Middle Schools. AB - Participating in school-based activities is linked to positive academic engagement and achievement, but less is known about how peer relationships within activities affect these outcomes. The current study examined friends in extracurricular activities as a predictor of academic outcomes in multiethnic middle schools in California. Specifically, the mediating role of school belonging, and interactions by ethnicity and type of activity, were examined in a sample including African American or Black, East or Southeast Asian, White, and Latino youth in extracurricular activities (N = 2268; Mage = 13.36 in eighth grade; 54% female). The results of multilevel mediational models suggested that school belonging mediated the link between friends in activities and academic outcomes, and these findings replicated across groups based on ethnicity and the type of activity in which one was involved in general. These results are discussed in terms of how activities can be structured to promote positive peer relations in ways that are linked with academic engagement and achievement. PMID- 29453739 TI - How is Civic Engagement Related to Personal Identity and Social Identity in Late Adolescents and Emerging Adults? A Person-Oriented Approach. AB - Adolescence and emerging adulthood are periods in life when individuals both question and define their place in society and form their identity. Meanwhile, active youth civic engagement represents a challenge for each democracy. The purpose of this study was to analyze the different forms of civic engagement among late adolescents and emerging adults and how they are related to personal identity and social identity, while adopting an integrative perspective through the lens of a person-oriented approach. The participants were 1217 (62.3% female) 16-24 year-old French students (M age = 19.17; SD age = 1.83). First, derived from cluster analyses, the findings emphasized diversity in civic engagement, from strong civic participation (in different formal and informal ways) to various forms of passivity. Diversity was also highlighted for personal identity and social identity profiles. Second, a Configural Frequency Analysis revealed a typical pattern associating passivity in civic engagement, personal carefree diffusion and rejection of social identity. Overall, these findings highlight an absence of general youth disaffection and provide a meaningful specific pattern for the understanding of passivity in political and civic matters in late adolescence and emerging adulthood. PMID- 29453740 TI - Arrestins: structural disorder creates rich functionality. AB - Arrestins are soluble relatively small 44-46 kDa proteins that specifically bind hundreds of active phosphorylated GPCRs and dozens of non-receptor partners. There are binding partners that demonstrate preference for each of the known arrestin conformations: free, receptor-bound, and microtubule-bound. Recent evidence suggests that conformational flexibility in every functional state is the defining characteristic of arrestins. Flexibility, or plasticity, of proteins is often described as structural disorder, in contrast to the fixed conformational order observed in high-resolution crystal structures. However, protein-protein interactions often involve highly flexible elements that can assume many distinct conformations upon binding to different partners. Existing evidence suggests that arrestins are no exception to this rule: their flexibility is necessary for functional versatility. The data on arrestins and many other multi-functional proteins indicate that in many cases, "order" might be artificially imposed by highly non-physiological crystallization conditions and/or crystal packing forces. In contrast, conformational flexibility (and its extreme case, intrinsic disorder) is a more natural state of proteins, representing true biological order that underlies their physiologically relevant functions. PMID- 29453741 TI - Fuel for the Work Required: A Theoretical Framework for Carbohydrate Periodization and the Glycogen Threshold Hypothesis. AB - Deliberately training with reduced carbohydrate (CHO) availability to enhance endurance-training-induced metabolic adaptations of skeletal muscle (i.e. the 'train low, compete high' paradigm) is a hot topic within sport nutrition. Train low studies involve periodically training (e.g., 30-50% of training sessions) with reduced CHO availability, where train-low models include twice per day training, fasted training, post-exercise CHO restriction and 'sleep low, train low'. When compared with high CHO availability, data suggest that augmented cell signalling (73% of 11 studies), gene expression (75% of 12 studies) and training induced increases in oxidative enzyme activity/protein content (78% of 9 studies) associated with 'train low' are especially apparent when training sessions are commenced within a specific range of muscle glycogen concentrations. Nonetheless, such muscle adaptations do not always translate to improved exercise performance (e.g. 37 and 63% of 11 studies show improvements or no change, respectively). Herein, we present our rationale for the glycogen threshold hypothesis, a window of muscle glycogen concentrations that simultaneously permits completion of required training workloads and activation of the molecular machinery regulating training adaptations. We also present the 'fuel for the work required' paradigm (representative of an amalgamation of train-low models) whereby CHO availability is adjusted in accordance with the demands of the upcoming training session(s). In order to strategically implement train-low sessions, our challenge now is to quantify the glycogen cost of habitual training sessions (so as to inform the attainment of any potential threshold) and ensure absolute training intensity is not compromised, while also creating a metabolic milieu conducive to facilitating the endurance phenotype. PMID- 29453742 TI - The Effect of Physical Activity Interventions on Glycosylated Haemoglobin (HbA1c) in Non-diabetic Populations: A Systematic Review and Meta-analysis. AB - BACKGROUND: Physical activity is widely perceived to be beneficial for preventing type 2 diabetes mellitus and for controlling glycaemic levels in patients with type 2 diabetes, but evidence supporting a positive effect in the control of glycaemic levels in healthy people is rather weak. The aim of this review was to estimate the effect of physical activity on glycaemic control measured by glycosylated haemoglobin (HbA1c) levels in non-diabetic populations, and to determine which type of physical activity has a greater influence on glycaemic control. METHODS: We systematically searched the MEDLINE, EMBASE, Cochrane Library and Web of Science databases, from inception to May 2017, for experimental studies addressing the effect of physical activity on glycaemic control measured by HbA1c levels in non-diabetic populations. The DerSimonian and Laird method was used to compute pooled estimates of effect size (ES) and respective 95% confidence intervals (CIs). The effect of physical activity on HbA1c levels was estimated in two ways: (1) physical activity intervention versus control; and (2) physical activity pre-post intervention. Additionally, subgroup analyses were performed based on age of participants and different aspects of the intervention. RESULTS: Fifteen published studies were included in the meta analysis. In analyses comparing physical activity intervention and control, we found a decrease of HbA1c levels in favour of the intervention group (ES = 0.32; 95% CI 0.01-0.62) with substantial heterogeneity (I2 = 63.2%; p = 0.008). In the pre-post analysis, there was a decrease in HbA1c levels post physical activity intervention (ES = 0.17; 95% CI 0.01-0.33) with low heterogeneity (I2 = 25.8%; p = 0.164). Additionally, for physical activity intervention versus control, a decrease in HbA1c levels was observed in resistance exercise and in intervention length below 12 weeks. Furthermore, for pre-post effect analyses, a decrease in HbA1c levels was observed in the supervised physical activity programme, other type of exercises, intervention length below 12 weeks and exercise intervention week duration above 150 min subgroups. CONCLUSIONS: This systematic review and meta-analysis provides an overview of the evidence supporting physical activity as a suitable intervention for glycaemic control as measured by HbA1c levels in non-diabetic populations. TRIAL REGISTRATION: PROSPERO CRD42016050991. PMID- 29453744 TI - Low Serum IgE Is a Sensitive and Specific Marker for Common Variable Immunodeficiency (CVID). AB - Although small prior studies have suggested that IgE can be low in common variable immunodeficiency (CVID), the workup for patients with recurrent infections and suspected hypogammaglobulinemia does not include the routine measurement of serum IgE. We sought to test the hypothesis that low/undetectable serum IgE is characteristic of CVID by comparing the frequency of low/undetectable serum IgE in healthy controls and patients with CVID. We measured total serum IgE in a large multi-center cohort of patients with CVID (n = 354) and compared this to large population-based cohorts of children and adults. We further compared IgE levels in patients with CVID to those with other forms of humoral immunodeficiency, and in a subset, measured levels of allergen specific serum IgE and IgG subclasses. Lastly, we evaluated for the presence of IgE in commercially available immunoglobulin replacement therapy (IgRT) products. An undetectable serum IgE (< 2 IU/ml) occurs in only 3.3% (95% CI, 1.9-5.7%) of the general population. In contrast, an undetectable IgE occurs in 75.6% (95% CI, 65.6-85.7%) of patients with CVID. Conversely, a high IgE (> 180 IU/ml) is very uncommon in CVID (0.3% of patients). IgE is > 2 IU/ml in 91.2% of patients with secondary hypogammaglobulinemia, and thus, an IgE < LLOD is suggestive of a primary humoral immunodeficiency. Allergen-specific IgE is not detectable in 96.5% of patients with CVID. Sufficient quantities of IgE to change the total serum IgE are not contained in IgRT. The IgG1/IgG4 ratio is increased in subjects with low IgE, regardless of whether they are controls or have CVID. These findings support the routine measurement of serum IgE in the workup of patients with hypogammaglobulinemia. PMID- 29453745 TI - Investigating the Effectiveness, Acceptability and Impact on Healthcare Usage of Providing a Cognitive-Behavioural Based Psychological Therapy Service for Patients with Primary Antibody Deficiency. AB - PURPOSE: Patients with primary antibody deficiency report poorer quality of life and higher rates of anxiety and depression than the general population. Cognitive behavioral therapy has been shown to be a valuable treatment for patients with other long-term physical health conditions, improving well-being and enabling them to manage their symptoms more effectively. The aim of this project was to establish the feasibility and effectiveness of providing cognitive-behavioral based therapy to patients with primary antibody deficiency. METHODS: Forty-four patients completed a course of psychological therapy. Participants completed a series of self-report measures examining psychological and physical health, and service usage, prior to starting treatment and following their final session. They also provided feedback on their experience of treatment. RESULTS: Patients showed improvements in anxiety, depression, insomnia and fatigue. There was a high level of acceptability of the service and the potential for long-term cost savings to the NHS. CONCLUSION: Psychological therapy based on the cognitive behavioral model of treatment appears to be a valuable treatment for patients with primary antibody deficiency and comorbid mental health difficulties. PMID- 29453743 TI - Neuromuscular Control Deficits and the Risk of Subsequent Injury after a Concussion: A Scoping Review. AB - An emerging area of research has identified that an increased risk of musculoskeletal injury may exist upon returning to sports after a sport-related concussion. The mechanisms underlying this recently discovered phenomenon, however, remain unknown. One theorized reason for this increased injury risk includes residual neuromuscular control deficits that remain impaired despite clinical recovery. Thus, the objectives of this review were: (1) to summarize the literature examining the relationship between concussion and risk of subsequent injury and (2) to summarize the literature for one mechanism with a theorized association with this increased injury risk, i.e., neuromuscular control deficits observed during gait after concussion under dual-task conditions. Two separate reviews were conducted consistent with both specified objectives. Studies published before 9 December, 2016 were identified using PubMed, Web of Science, and Academic Search Premier (EBSCOhost). Inclusion for the objective 1 search included dependent variables of quantitative measurements of musculoskeletal injury after concussion. Inclusion criteria for the objective 2 search included dependent variables pertaining to gait, dynamic balance control, and dual-task function. A total of 32 studies were included in the two reviews (objective 1 n = 10, objective 2 n = 22). According to a variety of study designs, athletes appear to have an increased risk of sustaining a musculoskeletal injury following a concussion. Furthermore, dual-task neuromuscular control deficits may continue to exist after patients report resolution of concussion symptoms, or perform normally on other clinical concussion tests. Therefore, musculoskeletal injury risk appears to increase following a concussion and persistent motor system and attentional deficits also seem to exist after a concussion. While not yet experimentally tested, these motor system and attentional deficits may contribute to the risk of sustaining a musculoskeletal injury upon returning to full athletic participation. PMID- 29453746 TI - Effect of Aerobic Exercise on Treg and Th17 of Rats with Ischemic Cardiomyopathy. AB - Immune activation and inflammation participate in the progression of chronic heart failure (CHF). Th17 cells and CD4+CD25+ regulatory T (Treg) cells both come from naive Th cells and share reciprocal development pathways but exhibit opposite effects. We hypothesized that the Th17/Treg balance was impaired in patients with CHF, and exercise can improve it. Rats with ischemic cardiomyopathy were prepared by ligaturing the left anterior descending branch of the left coronary artery. Rats in training group were trained with treadmill; Th17 cells increased significantly while Treg cells significantly decreased in s by flow cytometry, and the peripheral blood level of IL-6, IL-17, and TNF-alpha was obviously elevated by ELISA assay. We found that Th17/Treg balance is impaired in CHF rats, suggesting Th17/Treg imbalance potentially plays a role in the pathogenesis of CHF. Exercise can improve Th17/Treg imbalance, which also improves cardiac function of CHF. PMID- 29453747 TI - Clinical Applications of Patient-Specific Models: The Case for a Simple Approach. AB - Over the past several decades, increasingly sophisticated models of the heart have provided important insights into cardiac physiology and are increasingly used to predict the impact of diseases and therapies on the heart. In an era of personalized medicine, many envision patient-specific computational models as a powerful tool for personalizing therapy. Yet the complexity of current models poses important challenges, including identifying model parameters and completing calculations quickly enough for routine clinical use. We propose that early clinical successes are likely to arise from an alternative approach: relatively simple, fast, phenomenologic models with a small number of parameters that can be easily (and automatically) customized. We discuss examples of simple yet foundational models that have already made a tremendous impact on clinical education and practice, and make the case that reducing rather than increasing model complexity may be the key to realizing the promise of patient-specific modeling for clinical applications.

AB - PURPOSE: This cross-sectional study aimed to compare desire for social distance from people with mental illness in the disciplines of social work and psychology, and among students and professionals having different professional experience. METHODS: 948 respondents (715 students and 233 professionals) from Lithuanian educational and mental health-care institutions participated in an anonymous survey. Social distance was measured using Lithuanian Social Distance Scale which was created for this study. Participants also answered questions about familiarity with mental illness. Bias of social desirability was measured using the balanced inventory of desirable responding. RESULTS: Series of ANCOVA analysis revealed that psychology and social work master's and PhD students reported less social distance from people with mental illness when compared with bachelor's students. Familiarity with mental illness was significantly related to less social distance in the student sample, but not in professionals' sample. The strongest desire for social distance in the professionals' sample was observed in social workers having less than 5 years of professional practice and most experienced psychologists with more than 10 years of professional practice. CONCLUSIONS: Social distance from people with mental illness decreases through the study years; however, results of professional psychologists and social workers illustrate different trajectories in social distance through the professional career. The results of this study support the need for anti-stigma programmes and initiatives orientated towards mental health professionals. PMID- 29453749 TI - Lifelong robbery victimisation and mental disorders at age 18 years: Brazilian population-based study. AB - PURPOSE: Urban violence is a major problem in Brazil and may contribute to mental disorders among victims. The aim of this study was to assess the association between robbery victimisation and mental health disorders in late adolescence. METHODS: At age 18 years, 4106 participants in the 1993 Pelotas Birth Cohort Study were assessed. A questionnaire about history of robbery victimisation was administered, the Self-Report Questionnaire was used to screen for common mental disorders, and the Mini International Neuropsychiatric Interview was used to assess major depressive disorder and generalised anxiety disorder. Cross sectional prevalence ratios between lifetime robbery victimisation and mental disorders were estimated using Poisson regression with robust standard errors, adjusting for socioeconomic variables measured at birth and violence in the home and maltreatment measured at age 15. RESULTS: There was a dose-response relationship between frequency of lifetime robberies and risk of mental disorders. Adolescents who had been robbed three or more times had twice the risk (PR 2.04; 95% CI 1.64-2.56) for common mental disorders, over four times the risk for depression (PR 4.59; 95% CI 2.60-8.12), and twice the risk for anxiety (PR 1.93; 95% CI 1.06-3.50), compared with non-victims, adjusting for covariates. Experiencing frequent robberies had greater impact on common mental disorders than experiencing an armed robbery. Population attributable fractions with regard to robbery were 9% for common mental disorders, 13% for depression, and 8% for anxiety. CONCLUSIONS: Robberies are associated with common mental disorders in late adolescence, independently of violence between family members. Reducing urban violence could significantly help in preventing common mental illnesses.

AB - PURPOSE: Ewe's milk yogurt is richer in proteins, minerals and short- and medium chain fatty acids compared to cow's milk yogurt. We aimed to evaluate the effects of cow's milk yogurt (CW, 3.0% fat), semi-skimmed (ES, 2.8% fat) and whole ewe's milk yogurts (EW, 5.8% fat) on inflammatory markers and gut microbiota in subjects with borderline-high plasma cholesterol. METHODOLOGY: 30 adults (16 women) were randomized into a crossover study to consume 250 g/yogurt/day during three 5-week periods (4-week washouts). Plasma insulin, leptin, adhesion molecules, cytokines and gut microbiota composition (qPCR) were analysed. Rates of change were used to assess treatment effects both in the whole group and in subgroups of subjects with different cholesterol/HDL-c ratio (Cho-I group A: the top 6 women and 4 men values; Cho-I group B: remaining subjects). RESULTS: The yogurts showed no different effects on the inflammatory biomarkers or the microbiota of the whole group. However, ICAM-1 and P-selectin rates of change were lower after EW compared to CW and ES, respectively, in subjects of the Cho-I group A (P = 0.047 and P = 0.020). Women of this group showed lower MCP-1 rates of change after EW compared to ES and CW (P = 0.028, both). Blautia coccoides Eubacterium rectale decreased in women of the Cho-I group A during EW vs. ES (P = 0.028). CONCLUSION: Ewe's yogurt effects on inflammatory markers and microbiota were not different from those after cow's yogurt, but the attenuation of some inflammatory biomarkers with ewe's whole-milk yogurt in subjects with the highest TC/HDL-c deserves further study. PMID- 29453750 TI - Administration of Lactobacillus plantarum Lp62 to dam rats at the end of delivery and during lactation affects TGF-beta1 level and nutritional milk composition, and body weight of pups. AB - PURPOSE: Lactobacillus plantarum Lp62 is a lactic acid bacteria strain that has been isolated from cocoa beans and exhibited probiotic potential. The influence of oral administration of L. plantarum Lp62 on the growth of rat's pups; on yield, cytokines and milk composition was studied. METHODS: Lactobacillus plantarum Lp62 is a lactic acid bacteria strain that has been isolated from cocoa beans. It was administered daily by gavage to Wistar rats (n = 8), from the 7th day before delivery and for 20 days during lactation, in a concentration of 1.44 * 109 CFU/rat. The dam and pups were weighed and milk was collected at 12th and 19th day for determination of protein, triglycerides, cholesterol and lactose by colorimetric assays. TGF-beta1 milk levels were analyzed by ELISA. The mammary glands of rats were removed for histological analysis. To detect statistical differences between the groups, tests of mean differences at a significance level of 5% was performed. RESULTS: Supplementation with L. plantarum L62 resulted in significant higher weight of pups (p < 0.05), with similar weight on dams (p > 0.05). The milk yield was not altered by L. plantarum treatment, but the levels of protein, triglycerides and cholesterol were increased (p < 0.05), with no difference in lactose concentration (p > 0.05). Levels of TGF-beta1 were higher in the milk of L. plantarum treatment (p < 0.05). CONCLUSIONS: The treatment of dams at the end of pregnancy and lactation with L. plantarum Lp62 increased nutritional content of milk, probably contributing to the higher weight of the pups. The higher levels of TGF-beta1 in the milk, could promote immune benefits to the pups. Further studies in this field are needed to prove the potential use of L. plantarum Lp62 as a probiotic. PMID- 29453752 TI - Satisfied patients after shoulder arthrodesis for brachial plexus lesions even after 20 years of follow-up. AB - PURPOSE: Patients with an upper brachial plexus lesion can suffer from dysfunction, joint deformities and instability of the shoulder. The goal of this study was to determine pain, shoulder function, patient satisfaction and muscle strength in shoulder arthrodesis in patients with an upper brachial plexus lesion more than 15 years after surgery. METHODS: We retrospectively studied 12 patients with a brachial plexus lesion of mean age 46 years (27-61). At a mean of 19.8 years (15.4-30.3) after shoulder arthrodesis, patient-reported outcome measures (PROMs), range of motion (e.g., active and passive), patient satisfaction, strength of the affected and non-affected side (e.g., maximum isometric strength in Newton in forward and retroflexion, ab- and adduction, internal and external rotation) and position of fusion were obtained. PROMS consisted of the Visual Analogue Scale (VAS; 0-100, 0 being painless) for pain and the Disabilities of the Arm, Shoulder and Hand Score (DASH; 0-100, 0 being the best score) for function. RESULTS: At latest follow-up, the median VAS pain score was 49 (0-96) and 0 for, respectively, the affected and unaffected side. The DASH was 15 (8 46), meaning a reasonable to good function of the upper extremity. Active and passive retroflexion was significantly different (p = 0.028). All subjects stated that in the same situation they would undergo a shoulder arthrodesis again. The unaffected side was significantly stronger in every direction. Arthrodesis showed position of fusion of 31 degrees (12-70) abduction, 20 degrees (10-50) forward flexion and 22 degrees (- 14 to 58) internal rotation. The unaffected side was significantly (p <= 0.05) stronger in every movement direction. CONCLUSION: At a mean of 20 years after shoulder arthrodesis, patients with an upper brachial plexus lesion are still satisfied with a good to moderate functional improvement. LEVEL OF EVIDENCE III: A retrospective cohort study. PMID- 29453753 TI - Pediatric astrocytic tumor grading: comparison between arterial spin labeling and dynamic susceptibility contrast MRI perfusion. AB - PURPOSE: The aim of this study was to compare arterial spin labeling (ASL) and dynamic susceptibility contrast (DSC) MRI perfusion with respect to diagnostic performance in tumor grading in pediatric patients with low- and high-grade astrocytic tumors (AT). METHODS: We retrospectively analyzed 37 children with histologically proven treatment naive low- and high-grade AT who underwent concomitant pre-operative ASL and DSC MRI perfusion. Studies were performed on a 1.5 T scanner, and a pulsed technique was used for ASL. DSC data were post processed with a leakage correction software. Normalization of tumor perfusion parameters was performed with contralateral normal appearing gray matter. Normalized cerebral blood volume (nCBV) values in the most perfused area of each neoplasm were compared with normalized DSC-derived cerebral blood flow (nDSC-CBF) and ASL-derived cerebral blood flow (nASL-CBF) data, and correlated with WHO tumor grade. Statistics included Pearson's chi-square and Mann-Whitney U tests, Spearman's rank correlation, and receiver operating characteristic (ROC) analysis. RESULTS: A significant correlation was demonstrated between DSC and ASL data (p < 0.001). Significant differences in terms of DSC and ASL data were found between low- and high-grade AT (p < 0.001). ROC analysis demonstrated similar performances between all parameters in predicting tumor grade (nCBV: AUC 0.96, p < 0.001; nDSC-CBF: AUC 0.98, p < 0.001; nASL-CBF: AUC 0.96, p < 0.001). CONCLUSIONS: Normalized pulsed ASL performed with a 1.5 T scanner provides comparable results to DSC MRI perfusion in pediatric AT and may allow distinction between high- and low-grade AT. PMID- 29453755 TI - Effect of nicotine on repeated bouts of anaerobic exercise in nicotine naive individuals. AB - PURPOSE: Nicotine is a psychostimulant that is reported to be commonly supplemented by athletes. The purpose of the current study was to determine the effects of a rapidly absorbed form of nicotine on repeated bouts of anaerobic exercise, perception of exertion and a range of cardiovascular variables while monitoring side effect profiles. METHODS: Sixteen healthy, nicotine naive male athletes (24.1 +/- 5.3 years, 179.0 +/- 8.8 cm, 81.7 +/- 13.5 kg, BMI 25.5 +/- 3.0, Body fat% 13.2 +/- 5.1%) completed two repeated 30 s Wingate tests with 3 min rest between bouts following consumption of either a 5-mg oral-dispersible nicotine strip (NIC) or a flavour-matched placebo (PLA) in a randomised, double blind, cross-over design. Before the Wingate test, resting heart rate and blood pressure were also measured prior to and following PLA and NIC ingestion. RESULTS: Peak and average power output were significantly greater following NIC administration compared to PLA (P < 0.01). Similarly, significant increases were also seen in heart rate and blood pressure following NIC administration compared to PLA (P < 0.01). No significant effect on pre-exercise side effect score, reaction time, rate of perceived exertion or post exercise blood lactate levels were observed (P > 0.05). CONCLUSIONS: It was concluded that oral-dispersible nicotine strips increase repeated anaerobic performance, possibly through strong sympathetic stimulation, as evident by significant elevation of cardiovascular parameters. PMID- 29453754 TI - PACAP38 in human models of primary headaches. AB - BACKGROUND: To review the role of PACAP38 in human models of primary headaches, discuss possible mechanisms of PACAP38-induced migraine, and outline future directions. DISCUSSION: Experimental studies have established PACAP38 as a potent pharmacological "trigger" molecule of migraine-like attacks. These studies have also revealed a heterogeneous PACAP38 migraine response in migraine without aura patients. In addition, findings from brain imaging studies have demonstrated neuronal and vascular changes in migraine patients both ictally and interictally after PACAP38 infusion. CONCLUSION: Human migraine models have shed light on the importance of PACAP38 in the pathophysiology of primary headaches. These studies have also pointed to the PAC1 receptor and the PACAP38 molecule itself as target sites for drug testing. Future research should seek to understand the mechanisms underlying PACAP38-induced migraine. The results from an ongoing proof of concept randomized clinical trial may reveal the therapeutic potential of anti-PAC1 receptor antibodies for migraine prevention. PMID- 29453756 TI - Acute effects of unilateral static stretching on handgrip strength of the stretched and non-stretched limb. AB - PURPOSE: To determine the effects of an acute bout of unilateral static stretching on handgrip strength of both the stretched and non-stretched limb. It was reasoned that if the non-stretched limb experienced a decrease in force output, further evidence for a neural mechanism to explain a post-stretch force reduction would be obtained as no mechanical adaptation would have occurred. METHODS: Thirty participants performed maximum voluntary unilateral handgrip contractions of both limbs before and after stretching the finger flexors of the strength-dominant side only. Each trial was assessed for peak force, muscle activity (iEMG), and rate of force generation. RESULTS: Following the stretching bout, peak force and iEMG decreased by 4.4% (p = 0.001) and 6.4% (p = 0.000) respectively in the stretched limb only. However, rate of force generation was significantly impaired in both the stretched (- 17.3%; p = 0.000) and non stretched limbs (- 10.8%; p = 0.003) 1 min post-stretch, and remained similarly depressed for both limbs 15 min later. CONCLUSION: Acute stretching negatively impacts rate of force generation more than peak force. Moreover, a reduced rate of force generation from the non-stretched limb indicates the presence of a cross over inhibitory effect through the nervous system, which provides additional evidence for a neural mechanism. PMID- 29453758 TI - Theoretical study on the optical response behavior to hydrogen chloride gas of a series of Schiff-base-based star-shaped structures. AB - Schiff-base compounds have many applications in the field of optoelectronic materials and chemical sensing because of their appealing coordination ability, and simple and easily accessible use in structural modification. Herein, five kinds of star-shaped Schiff-base compounds were designed and their optical response behavior to hydrogen chloride (HCl) gas was studied using dependent/time dependent density functional theory (DFT/TDDFT). Moreover, the relationship between structures and properties was investigated upon changing the benzene group into N atom or triazine group at the core-position and introducing a methoxyl (-OCH3) or nitro (-NO2) group into the star-shaped Schiff-bases at the tail of the branches. The results show that all five Schiff-bases could be candidates for HCl gas sensing materials. Furthermore, introducing an electron donating group at either the core or the tail forms a charge transfer channel with the electron deficient H-bonded imino group, which is convenient for charge transfer and subsequently promotes a red-shift in absorption spectra and fluorescence quenching. PMID- 29453757 TI - Localization of epithelial sodium channel (ENaC) and CFTR in the germinal epithelium of the testis, Sertoli cells, and spermatozoa. AB - Spermatogenesis starts within the seminiferous tubules of the testis by mitotic division of spermatogonia that produces spermatocytes. Meiotic division of these spermatocytes produces haploid spermatids that differentiate into spermatozoa. In this study, we examined the expression of ENaC and CFTR (a Cl- channel) in rat testicular sections using confocal microscopic immunofluorescence. The structural integrity of the seminiferous tubule sections was verified by precise phalloidin staining of the actin fibers located abundantly at both basal and adluminal tight junctions. The acrosome forming regions in the round spermatids were stained using an FITC coupled lectin (wheat germ agglutinin). In all phases of the germ cells (spermatogonia, spermatocytes, and spermatids) ENaC was localized in cytoplasmic pools. Prior to spermiation, ENaC immunofluorescence appeared along the tails of the spermatids. In spermatozoa isolated from the epididymis, ENaC was localized at the acrosome and a central region of the sperm flagellum. The mature sperm are transcriptionally silent. Hence, we suggest that ENaC subunits in cytoplasmic pools in germ cells serve as the source of ENaC subunits located along the tail of spermatozoa. The locations of ENaC is compatible with a possible role in the acrosomal reaction and sperm mobility. In contrast to ENaC, CFTR immunofluorescence was most strongly observed specifically within the Sertoli cell nuclei. Based on the nuclear localization of CFTR we suggest that, in addition to its role as an ion channel, CFTR may have an independent role in gene regulation within the nuclei. PMID- 29453759 TI - Systemic Treatment of Patients with Advanced, Unresectable Hepatocellular Carcinoma: Emergence of Therapies. AB - To date, sorafenib, a multiple tyrosine kinase inhibitor, is the only systemic agent approved by the FDA in the first-line treatment of patients with unresectable hepatocellular carcinoma (HCC). Several other tyrosine kinase inhibiting agents have been investigated in the first-line setting, either alone (sunitinib, brivanib, linifanib, and lenvatinib) or in combination with sorafenib (erlotinib and doxorubicin) in phase 3 trials. However, none of these studies demonstrated an improvement in survival over sorafenib. Many agents have also been tested in patients with HCC whose disease has progressed on sorafenib, but regorafenib is the only one to have demonstrated efficacy in this setting in a randomized, phase 3 trial. There were no clear survival benefits shown with everolimus, brivanib, or ramucirumab as second-line therapy. Nivolumab has also shown promising efficacy in patients with HCC who progressed on sorafenib, which was recently granted approval by the FDA, although larger confirmative trials may be considered. The treatment landscape for patients with advanced unresectable hepatocellular tumors has remained fairly static for the past 10 years, with multiple failed trials yield little change in the way these patients might be treated. However, recent findings for regorafenib, lenvatinib, and nivolumab have led to the most significant changes in the treatment paradigm in years.

PMID- 29453761 TI - Expression Level of miR-34a in Tumor Tissue from Patients with Esophageal Squamous Cell Carcinoma. AB - BACKGROUND: miR-34a has been shown to be involved in P53 regulation. In this study, we aimed to evaluate the expression level of miR-34a in esophageal cancer and compare it with that of the normal marginal tissues. METHODS: Tumor and marginal tissues were obtained from 50 patients with esophageal cancer. After RNA extraction, expression level of miR-34a was determined using SYBR green master mix and real-time quantitative PCR. RESULTS: It was observed that there was a downregulation of miR-34a in tumoral tissue of esophageal patients in comparison to normal marginal tissues. Moreover, the expression level of miR-34a was correlated with clinicopathological specifications of the patients. CONCLUSIONS: miR-34a may be involved in the pathogenesis and development of esophageal cancer and have the potential to be used as a diagnostic and therapeutic marker in esophageal cancer.

PMID- 29453763 TI - Testing the Grossman model of medical spending determinants with macroeconomic panel data. AB - Michael Grossman's human capital model of the demand for health has been argued to be one of the major achievements in theoretical health economics. Attempts to test this model empirically have been sparse, however, and with mixed results. These attempts so far relied on using-mostly cross-sectional-micro data from household surveys. For the first time in the literature, we bring in macroeconomic panel data for 29 OECD countries over the period 1970-2010 to test the model. To check the robustness of the results for the determinants of medical spending identified by the model, we include additional covariates in an extreme bounds analysis (EBA) framework. The preferred model specifications (including the robust covariates) do not lend much empirical support to the Grossman model. This is in line with the mixed results of earlier studies. PMID- 29453764 TI - Comparative analysis of human UCB and adipose tissue derived mesenchymal stem cells for their differentiation potential into brown and white adipocytes. AB - The differentiation potential of umbilical cord blood-derived mesenchymal stem cells (UCB-MSCs) into brown and white adipocytes in comparison to Adipose tissue derived MSCs (AD-MSCs) were investigated in order to characterize their potency for future cell therapies. MSCs were isolated from ten UCB samples and six liposuction materials. MSCs were differentiated into white and brown adipocytes after characterization by flow cytometry. Differentiated adipocytes were stained with Oil Red O and hematoxylin/eosin. The UCP1 protein levels in brown adipocytes were investigated by immunofluoresence and western blot analysis. Cells that expressed mesenchymal stem cells markers (CD34-, CD45-, CD90+ and CD105+) were successfully isolated from UCB and adipose tissue. Oil Red O staining demonstrated that white and brown adipocytes obtained from AD-MSCs showed 85 and 61% of red pixels, while it was 3 and 1.9%, respectively for white and brown adipocytes obtained from UCB-MSCs. Fluorescence microscopy analysis showed strong uncoupling protein 1 (UCP1) signaling in brown adipocytes, especially which were obtained from AD-MSCs. Quantification of UCP1 protein amount showed 4- and 10.64 fold increase in UCP1 contents of brown adipocytes derived from UCB-MSCs and AD MSCs, respectively in comparison to undifferentiated MSCs (P < 0.004). UCB-MSCs showed only a little differentiation tendency into adipocytes means it is not an appropriate stem cell type to be differentiated into these cell types. In contrast, high differentiation efficiency of AD-MSCs into brown and white adipocytes make it appropriate stem cell type to use in future regenerative medicine of soft tissue disorders or fighting with obesity and its related disorders. PMID- 29453765 TI - Statistical assessment of DNA extraction methodology for culture-independent analysis of microbial community associated with diverse environmental samples. AB - Cost-effectiveness, quality, time-effectiveness and ease of the methodology are the most crucial factors in isolating quality DNA from wide variety of samples. Thus, research efforts focusing on the development of an efficient DNA extraction protocol is the need of the hour. The present study therefore, focuses on development of an efficient, rapid and free of inhibitory substances based methodology for extracting metagenomic DNA from diverse environmental samples viz. anaerobic biogas digesta, ruminant stomach, human feces, soil, and microbial starter cultures used for preparation of fermented food. PCR-DGGE based analysis and quality metagenomic library preparation, using DNA extraction methodology, validates the developed protocol. The developed protocol is cost effective, capable of isolating DNA from small sample size (100-1000 ul), time efficient (1.5-2.0 h protocol) and results in significantly higher DNA yield (4-8 times increased yield) when compared to previously available DNA extraction method and a commercial DNA extraction kit. The DNA extracted from the samples using different protocols was evaluated based on its ability to identify diverse microbial species using PCR-DGGE profiles targeting variable region within the 16S rRNA gene. The results of microbial community analysis revealed comparability of the developed protocol to commercial kits, in effectively identifying dominant representatives of the microbial community in different samples. Using the DNA extracted from the presented methodology, metagenomic libraries were prepared, which were found suitable for sequencing on Illumina platform. PMID- 29453766 TI - Spondylodiscitis due to Aerococcus urinae and literature review. AB - INTRODUCTION: Aerococccus urinae (AU) is a pathogen mainly identified in male urinary tract infections and responsible for bacteremia and endocarditis. To the best of our knowledge, there are only five patients with osteomyelitis due to AU described in the literature. All of them had urinary tract disease or systemic conditions such as diabetes, and two were associated with an endocarditis. CASE REPORT: We described the first case of isolated spondylodiscitis without general or local predisposing condition, excepted age > 65 years. PMID- 29453767 TI - Increasing connectivity between metapopulation ecology and landscape ecology. AB - Metapopulation ecology and landscape ecology aim to understand how spatial structure influences ecological processes, yet these disciplines address the problem using fundamentally different modeling approaches. Metapopulation models describe how the spatial distribution of patches affects colonization and extinction, but often do not account for the heterogeneity in the landscape between patches. Models in landscape ecology use detailed descriptions of landscape structure, but often without considering colonization and extinction dynamics. We present a novel spatially explicit modeling framework for narrowing the divide between these disciplines to advance understanding of the effects of landscape structure on metapopulation dynamics. Unlike previous efforts, this framework allows for statistical inference on landscape resistance to colonization using empirical data. We demonstrate the approach using 11 yr of data on a threatened amphibian in a desert ecosystem. Occupancy data for Lithobates chiricahuensis (Chiricahua leopard frog) were collected on the Buenos Aires National Wildlife Refuge (BANWR), Arizona, USA from 2007 to 2017 following a reintroduction in 2003. Results indicated that colonization dynamics were influenced by both patch characteristics and landscape structure. Landscape resistance increased with increasing elevation and distance to the nearest streambed. Colonization rate was also influenced by patch quality, with semi permanent and permanent ponds contributing substantially more to the colonization of neighboring ponds relative to intermittent ponds. Ponds that only hold water intermittently also had the highest extinction rate. Our modeling framework can be widely applied to understand metapopulation dynamics in complex landscapes, particularly in systems in which the environment between habitat patches influences the colonization process. PMID- 29453768 TI - Mental Rotation in False Belief Understanding. AB - This study examines the spontaneous use of embodied egocentric transformation (EET) in understanding false beliefs in the minds of others. EET involves the participants mentally transforming or rotating themselves into the orientation of an agent when trying to adopt his or her visuospatial perspective. We argue that psychological perspective taking such as false belief reasoning may also involve EET because of what has been widely reported in the embodied cognition literature, showing that our processing of abstract, propositional information is often grounded in concrete bodily sensations which are not apparently linked to higher cognition. In Experiment 1, an agent placed a ball into one of two boxes and left. The ball then rolled out and moved either into the other box (new box) or back into the original one (old box). The participants were to decide from which box they themselves or the agent would try to recover the ball. Results showed that false belief performance was affected by increased orientation disparity between the participants and the agent, suggesting involvement of embodied transformation. In Experiment 2, false belief was similarly induced and the participants were to decide if the agent would try to recover the ball in one specific box. Orientation disparity was again found to affect false belief performance. The present results extend previous findings on EET in visuospatial perspective taking and suggest that false belief reasoning, which is a kind of psychological perspective taking, can also involve embodied rotation, consistent with the embodied cognition view. PMID- 29453769 TI - Human papilloma virus genotyping for the cross-sectional and longitudinal probability of developing cervical intraepithelial neoplasia grade 2 or more. AB - Human papilloma virus (HPV) testing is more sensitive but less specific than cytology. We evaluated stand-alone genotyping as a possible triage method. During a multicentre randomised controlled trial comparing HPV testing to conventional cytology, HPV-positive women were referred to colposcopy and followed up if no high-grade lesion was detected. HPV-positive samples were genotyped by GP5+/GP6+ primed polymerase chain reaction followed by reverse line blot. Genotypes were hierarchically ordered by positive predictive value (PPV) for CIN grade 2 or more (CIN2+), and grouped by cluster analysis into three groups (A, B and C in decreasing order). Receiver operating characteristic curves were computed. Among 2,255 HPV-positive women with genotyping, 239 CIN2+ (including 113 CIN3+) were detected at baseline or during a 3-year follow-up. HPV33 had the highest PPV with CIN2+ and CIN3+ as the endpoint and when considering lesions detected at baseline or also during follow-up. HPV16 and HPV35 were the second and third, respectively. Cross-sectional sensitivity for CIN2+ at baseline was 67.3% (95% CI 59.7-74.2), 91.8% (95% CI 86.6-95.5) and 94.7% (95% CI 90.2-97.6), respectively, when considering as "positive" any of the HPV types in group A (33, 16 and 35), A or B (31, 52, 18, 59 and 58) and A or B or C (39, 51, 56, 45 and 68). The corresponding cross-sectional PPVs for CIN2+ were 15.8% 95% (CI 13.2-18.7), 12.0% (95% CI 10.3-13.9) and 9.6% (95% CI 8.2-11.1), respectively. HPV33, 16 and 35 confer a high probability of CIN2+ but this rapidly decreases when adding other genotypes.

AB - PURPOSE: To evaluate the effect of incision design in implant surgery on interproximal bone loss of posterior teeth adjacent to interdental single implants, comparing intrasulcular and paramarginal incision. A further aim was to assess the influence of the incision technique on peri-implant bone remodeling. MATERIALS AND METHODS: A controlled randomized clinical trial was carried out in a University Clinic. All the patients received an interdental posterior single implant. The incision type was randomly divided into two groups: (a) intrasulcular or (b) paramarginal. Standardized periapical digital radiographs were made with the parallel technique and a silicone index individualized in each patient. Radiographs were made immediately after implant placement, at abutment connection, 6 and 12 months post-loading. Two radiographic reference points were detected at the interproximal aspect of the adjacent teeth: (A) the cementoenamel junction and (B) the most coronal aspect of the bone crest. The interproximal bone loss of the adjacent teeth was calculated as the difference from A to B between the different follow-up periods and baseline. Two different examiners evaluated the radiographic measurements twice. RESULTS: Sixty patients, each with one implant, were included, 30 in each group. A mean interproximal bone loss in teeth of 0.09 mm in the intrasulcular and 0.10 mm in the paramarginal group was found at 12 months post-loading. Mean peri-implant bone remodeling was 0.17 mm in the intrasulcular group and 0.15 mm in the paramarginal group. Differences between incision types were not statistically significant (p > .05). CONCLUSIONS: Both incision designs used to place interdental single implants resulted in minimum bone loss at the interproximal aspect of adjacent teeth. The incision design did not significantly influence the radiographically assessed interproximal bone loss nor peri-implant bone remodeling. PMID- 29453773 TI - Electrospray ionization source with a rear extractor. AB - A new electrospray source design is introduced by having an extractor electrode placed at 1 to 2 mm behind the emitter tip. The extractor was integrated into the sprayer body as a single device. An insulating tube was used to isolate the emitter from the extractor and to deliver the sheath gas for the electrospray. The electric field strength at the emitter was primarily determined by the relative position and the potential between the needle and the extractor; therefore, the spraying condition was insusceptible to the change of sprayer position or orientation with respect to the ion sampling inlet. Such design allowed the use of much lower operating voltage and facilitated the optimization of sprayer position by keeping the electric field parameter constant. Using an emitter capillary of 150 and 310 MUm in inner and outer diameters, strong ion signal could still be acquired with 2-kV emitter potential even if the distance between the emitter and ion inlet was extended to >70 mm. Charge reduction of protein ions using 2 extractor-based electrosprays of opposite emitter polarities was also demonstrated.

AB - Accumulation of advanced glycation end products (AGEs) in articular cartilage is thought to represent a major risk factor for osteoarthritis development. In this study we aimed to probe the role of AGEs in human chondrocytes and to determine the impact of the peroxisome proliferator-activated receptor-gamma (PPARG) on AGEs-induced cell autophagy. Cell viability was measured after human chondrocytes were treated with different concentrations of AGEs with or without the PPARG inhibitor, T0070907, or agonist, pioglitazone. Autophagy activation markers (MAP2LC3, BECN1 and SQSTM1/P62), expression of PPARG and the phosphorylation levels of Akt/MTOR were determined by Western blotting; autophagosome formation was analyzed by transmission electron microscopy (TEM); autophagic flux was detected with mRFP-GFP-LC3 tandem construct. Low doses of AGEs over a short amount of time stimulated chondrocyte proliferation and autophagy by limiting phosphorylation of Akt/MTOR signaling. The addition of PPARG inhibitor T0070907 lead to defective autophagy. High dose and long exposure to AGEs inhibited cell viability and autophagy by increasing phosphorylation levels of Akt/MTOR signaling. The agonist, pioglitazone, was shown to protect cell autophagy in a dose-dependent manner. Our findings suggest AGEs can downregulate PPARG and that PPARG maintains cell viability by activating the Akt/MTOR signaling pathway as well as inducing chondrocyte autophagy.

Syndromic forms do rarely exist with associated cerebral and ocular malformations. The skin lesions are pale at birth and become irregular by puberty. In the adult patient, tumors (usually benign) develop from sebaceous nevus. Their surgical excision during childhood can give a better result in terms of the definitive scar. OBJECTIVES: The aim of this study is to analyze our cases of syndromic sebaceous hamartoma, perform a review of the existing literature, and propose guidelines for the therapeutic plan. METHODS: This is a retrospective study reviewing the cases of syndromic sebaceous nevus treated in the Department of Orthopedic Plastic Pediatric Surgery in Montpellier, France, and the Department of Pediatric Surgery in Lausanne, Switzerland, between 1994 and 2016. RESULTS: The files of six patients with syndromic sebaceous nevus were analyzed. The average age at the first consultation was 4 months. The location was craniofacial in all cases. Cerebral radiological imaging was performed on all patients; two showed abnormal findings. Four patients underwent ophthalmic examination, which all revealed abnormalities. Three patients had other associated malformations. Three patients presented with epilepsy or learning difficulties in the course of follow-up. CONCLUSION: All patients presenting with extensive sebaceous nevus of the craniofacial region should benefit from cerebral imagery and ophthalmic examination since there is a very high probability of associated abnormalities. The developmental problems encountered could not be definitively associated with the skin malformations.

AB - Allopregnanolone (5alpha-pregnan-3alpha-ol-20-one) and its synthetic 3beta-methyl analog, ganaxolone, are positive allosteric modulators of synaptic and extrasynaptic gamma-aminobutyric acid (GABA)A receptors that exhibit antiseizure activity in diverse animal seizure models, including models of status epilepticus (SE). The 2 neuroactive steroids are being investigated as treatments for SE, including as a treatment for SE induced by chemical threat agents. Intramuscular injection is the preferred route of administration in the prehospital treatment of SE. The objective of this study was to assess the efficacy of intramuscular allopregnanolone and ganaxolone in the treatment of SE induced by the chemical threat agent tetramethylenedisulfotetramine (TETS). The test agents were administered 40 minutes after the onset of SE when mice are refractory to treatment. Allopregnanolone and ganaxolone (each at 3 mg/kg) terminated SE in, respectively, 92% and 75% of animals, and prevented mortality in 85% and 50% of animals; the mean times to termination of behavioral seizures were, respectively, 172 +/- 16 and 447 +/- 52 seconds. In a separate series of experiments, mice were dosed with the neuroactive steroids by intramuscular injection, and plasma and brain levels were sampled at various time points following injection to estimate pharmacokinetic parameters. Plasma Cmax (maximum concentration) values for allopregnanolone and ganaxolone were 645 and 550 ng/mL, respectively. Brain exposure of both steroids was approximately 3-fold the plasma exposure. Two compartment pharmacokinetic analysis revealed that the central compartment Vd (volume of distribution), CL (clearance), t1/2 (terminal half-life), and F (intramuscular bioavailability) values for allopregnanolone and ganaxolone were, respectively, 4.95 L/kg 12.88 L/kg/h,16 minutes, 97%, and 5.07 L/kg, 8.35 L/kg/h, 25 minutes, 95%. Allopregnanolone and ganaxolone are effective in the treatment of TETS-induced SE when administered by the intramuscular route. Allopregnanolone is more rapidly acting and modestly more effective, possibly because it has greater potency on GABAA receptors. PMID- 29453778 TI - 'I'm happy to own my implicit biases': Public encounters with the implicit association test. AB - The implicit association test (IAT) and concept of implicit bias have significantly influenced the scientific, institutional, and public discourse on racial prejudice. In spite of this, there has been little investigation of how ordinary people make sense of the IAT and the bias it claims to measure. This article examines the public understanding of this research through a discourse analysis of reactions to the IAT and implicit bias in the news media. It demonstrates the ways in which readers interpreted, related to, and negotiated the claims of IAT science in relation to socially shared and historically embedded concerns and identities. IAT science was discredited in accounts that evoked discourses about the marginality of academic preoccupations, and helped to position test-takers as targets of an oppressive political correctness and psychologists as liberally biased. Alternatively, the IAT was understood to have revealed widely and deeply held biases towards racialized others, eliciting accounts that took the form of psychomoral confessionals. Such admissions of bias helped to constitute moral identities for readers that were firmly positioned against racial bias. Our findings are discussed in terms of their implications for using the IAT in prejudice reduction interventions, and communicating to the public about implicit bias. PMID- 29453779 TI - Mitochondrial cytochrome P450 (CYP) 1B1 is responsible for melatonin-induced apoptosis in neural cancer cells. AB - Melatonin is an endogenous indoleamine with a wide range of biological functions in the various organisms from bacteria to mammals. Evidence indicates that melatonin facilitates apoptosis in cancer cells and enhances the antitumor activity of chemotherapy in animals and clinical studies. However, the melatonin metabolism and the key metabolic targets in cancer cells still remain unknown. In this study, U118 and SH-SY5Y tumor cell lines were used to investigate the metabolic pathways of melatonin in cancer cells. Interestingly, the inhibitory effect of melatonin on proliferation in SH-SY5Y cells is more potent than that in U118 cells. In contrast, this inhibitory effect on the normal cells is absent. The antitumor effects of melatonin are positively associated with its metabolite N-acetylserotonin (NAS). Unexpectedly, CYP1B1 is, for first time, identified to localize in the mitochondria of tumor cells, and it metabolizes melatonin to form NAS in situ, which subsequently triggers mitochondria-dependent apoptosis in cancer cells. In normal cells, NAS does not induce apoptosis. A remarkable individual variation on CYP1B1 expression was also detected in human tumor tissue. These findings provide the novel mechanisms regarding the antitumor effects of melatonin in the level of mitochondria. Thus, we hypothesize that CYP1B1 overexpression in mitochondria would significantly enhance the antitumor effects of melatonin. Mitochondrial CYP1B1 can potentially serve as a specific target to modify the therapeutic and biological effects of melatonin on cancer patients.

AB - OBJECTIVES: Collagen membranes are not limited to be occlusive barriers as they actively support bone regeneration. However, the impact of bone-derived growth factors on their osteoconductive competence has not been examined. METHODS: Twenty adult Sprague Dawley rats were included in the study. Calvaria defects with a diameter of five millimeter were created. The defect was covered with one layer of a collagen membrane previously soaked in conditioned medium of porcine bone chips or in culture medium alone. After 4 weeks, microcomputed tomography was performed. Undecalcified thin-ground sections were subjected to light and scanning electron microscopy. Primary outcome parameter was the bone volume in the defect. Unit of analysis was the bone-conditioned medium (BCM). RESULTS: In the central defect area of the control and the BCM group, median new bone connected to the host bone was 0.54 and 0.32 mm3, respectively (p = .10). In the ectocranial defect area, the control group showed significantly more bone than the BCM group (0.90 and 0.26 mm3; p = .02). Based on an exploratory interpretation, the control group had smaller bony islands than the BCM group. Scanning electron microscopy and histology indicate the formation of bone but also the collagen membrane to be mineralized in the defect site. CONCLUSIONS: These results demonstrate that the commercial collagen membrane holds an osteoconductive competence in a rat calvaria defect model. Soaking collagen membranes with BCM shifts bone formation toward the formation of bony islands rather than new bone connected to the host bone.

AB - This study analyses the discourse of statements of the leaders of two Greek political parties commemorating the restoration of Greek democracy on 24 July 1974; the ruling party New Democracy and the opposition, Coalition of the Radical Left. We focus on how these leaders act as entrepreneurs of their identities by constructing their ingroups in broad or narrow terms and their outgroups in vague or specific terms. These constructions were ventured during a period of relative political stability (2008) and instability (2012), and we focus on how ingroup prototypes and group boundaries are narrated across Greece's past, present and future in ambiguous or concrete terms. The study aligns the social identity approach to political leadership with studies on political discourse and 'the rhetoric of we'. We view commemorative statements as historical charters and respond to calls for discourse analysis to take greater account of historical context. The findings suggest concrete hypotheses about how leaders with different amounts of political support might define, as identity entrepreneurs, who 'we' are, and who 'we' are not in democratic contexts marked by stability or crisis.

Case report. AB - Collateral circulation secondary to liver cirrhosis may cause the development of large PSSs that may steal flow from the main portal circulation. It is important to identify these shunts prior to, or during the transplant surgery because they might cause an insufficient portal flow to the implanted graft. There are few reports of "steal flow syndrome" cases in pediatrics, even in biliary atresia patients that may have portal hypoplasia as an associated malformation. We present a 12-month-old female who received an uneventful LDLT from her mother, and the GRWR was 4.8. During the early post-operative period, she became hemodynamically unstable, developed ascites, and altered LFT. The post-operative ultrasound identified reversed portal flow, finding a non-anatomical PSS. A 3D CT scan confirmed the presence of a mesocaval shunt through the territory of the right gonadal vein, draining into the right iliac vein, with no portal inflow into the liver. The patient was re-operated, and the shunt was ligated. An intraoperative Doppler ultrasound showed adequate portal inflow after the procedure; the patient evolved satisfactorily and was discharged home on day number 49. The aim was to report a case of post-operative steal syndrome in a pediatric recipient due to a mesocaval shunt not diagnosed during the pretransplant evaluation. PMID- 29453783 TI - Affordances after spinal cord injury. AB - Spinal cord injury can cause cognitive impairments even when no cerebral lesion is appreciable. As patients are forced to explore the environment in a non canonical position (i.e., seated on a wheelchair), a modified relation with space can explain motor-related cognitive differences compared to non-injured individuals. Peripersonal space is encoded in motor terms, that is, in relation to the representation of action abilities and is strictly related to the affordance of reachability. In turn, affordances, the action possibilities suggested by relevant properties of the environment, are related to the perceiver's peripersonal space and motor abilities. One might suppose that these motor-related cognitive abilities are compromised when an individual loses the ability to move. We shed light on this issue in 10 patients with paraplegia and 20 matched controls. All have been administered an affordances-related reachability judgement task adapted from Costantini, Ambrosini, Tieri, Sinigaglia, and Committeri (2010, Experimental Brain Research, 207, 95) and neuropsychological tests. Our findings demonstrate that patients and controls show the same level of accuracy in estimating the location of their peripersonal space boundaries, but only controls show the typical overestimation of reaching range. Secondly, patients show a higher variability in their judgements than controls. Importantly, this finding is related to the patients' ability to perform everyday tasks. Finally, patients are not faster in making their judgements on reachability in peripersonal space, while controls are. Our results suggest that not moving freely or as usual in the environment impact decoding of action-related properties even when the upper limbs are not compromised.

AB - The complex formation of the following diazaperylene ligands (L) 1,12 diazaperylene 1, 1,1'-bisisoquinoline 2, 2,11-disubstituted 1,12-diazaperylenes (alkyl = methyl, ethyl, isopropyl, 3, 5, 7), 3,3'-disubstituted 1,1' bisisoquinoline (alkyl = methyl, ethyl, isopropyl, 4, 6, 8 and with R = phenyl, 11 and with pyridine 12), and the 5,8-dimethoxy-substituted diazaperylene 9, 6,6' dimethoxy-substituted bisisoquinoline 10 with AgBF4 was investigated. Collision induced dissociation measurements were used to evaluate the relative stabilities of the ligands themselves and for the [1:1]+ complexes as well as for the homoleptic and heteroleptic silver [1:2]+ complexes in the gas phase. This method is very useful in rapid screening of the stabilities of new complexes in the gas phase. The influence of the spatial arrangement of the ligands and the type of substituents employed for the complexation were examined. The effect of the preorganization of the diazaperylene on the threshold activation voltages and thus of the relative binding energies of the different complexes are discussed. Density functional theory calculations were used to calculate the optimized structures of the silver complexes and compared with the stabilities of the complexes in the gas phase for the first time. PMID- 29453785 TI - Assessment of antiplaque effectiveness of chlorhexidine-soaked gauze compared to chlorhexidine mouth rinse: Randomized clinical trial. AB - AIM: The aim of the present study was to compare the efficacy of a disposable gauze soaked with chlorhexidine and rolled up on the finger vs chlorhexidine mouth rinse (CM) to maintain oral hygiene. METHODS: In this single-blind, randomized trial, both groups were instructed to brush their teeth and use the 0.12% chlorhexidine intervention twice per day (experimental group: toothbrushing + chlorhexidine-soaked gauze; control group: toothbrushing + mouth rinse). The main outcome was the change in full mouth plaque index scores from baseline to 2 weeks. Secondary outcomes were the patient's appreciation (visual analog scale) and the bleeding index. RESULTS: The final sample consisted of 60 young patients: 31 in the experimental group and 29 in the control group. After 2 weeks, both interventions were effective in reducing plaque index. The percentage of score reduction was 33% in the experimental group and 30% for the controls, with no significant difference between groups. Both interventions reduced the bleeding index, but this reduction was significant only in the experimental group (P < .001). CONCLUSIONS: There is no difference between chlorhexidine-soaked gauze and CM regarding plaque control. In addition, gauze soaked with chlorhexidine was significantly more effective in reducing the bleeding index score and was appreciated by the patients. PMID- 29453786 TI - Long-term outcomes of 6-mm diameter fully covered self-expandable metal stents in benign refractory pancreatic ductal stricture. AB - BACKGROUND AND AIM: Fully covered self-expandable metal stent (FCSEMS) placement has been tried for pancreatic ductal strictures in chronic pancreatitis. However, the long-term outcome of this procedure remains unknown. The present study aimed to investigate the procedural and long-term outcomes of FCSEMS placement in patients with benign refractory pancreatic ductal strictures. METHODS: Between August 2011 and September 2015, 18 patients underwent endoscopic treatment with FCSEMS for benign refractory pancreatic ductal stricture. Technical success, clinical success, radiological success, and adverse events were assessed. RESULTS: Stent placement was successful in all patients (technical success rate, 100%). Reduction in pain score of >50% was achieved in 15 of the 18 patients (clinical success rate, 83.3%). In all patients, stents could easily be removed at a median of 7.5 months (interquartile range [IQR], 6-13.6) after their insertion. FCSEMS migration did not develop in any patient. Ductal stricture was improved in 15 patients (radiological success rate, 83.3%). After definite stent removal, 13 of the 15 (86.7%) patients who had responded to pancreatic stenting maintained the response during follow up (median of 47.3 months; IQR, 7.4-57.1). CONCLUSIONS: FCSEMS placement appears to be safe and effective for the treatment of benign refractory pancreatic ductal strictures as it can provide persistent improvement in the stricture in long-term follow up. PMID- 29453788 TI - Hard and soft tissue changes around implants activated using plasma of argon: A histomorphometric study in dog. AB - OBJECTIVE: To histologically assess the hard and soft tissue changes after insertion of cleaned and activated titanium implants using plasma of argon. MATERIALS AND METHODS: Eight dogs were included in this study. The mandibular premolars and first molars were extracted. For each hemi-mandible, four implants, 7 mm long and 3.3 mm of diameter, with a ZirTi surface were used. The surface of two implants was randomly treated with argon plasma (test), while the other two implants were left untreated (control). After 1 month, the same procedure was performed in the contralateral hemi-mandible. The amount of old bone, new bone, overall value of old bone plus new bone, and soft tissue was histologically evaluated. RESULTS: After 1 month of healing, high percentages of new bone in close contact with the implant surface were found at both the treated (60.1% +/- 15.6%; 95% CI 56.5%-78.0%) and untreated (57.2% +/- 13.1%; 95% CI 49.3%-67.5%) implants. Low percentages of old bone were found at this stage of healing, at both the treated (4.4% +/- 3.0%; 95% CI 1.2%-5.4%) and untreated (3.4% +/- 3.1%; 95% CI 0.6%-4.9%) implants. Not statistically significant differences were found between groups (p > .05). After 2 months of healing, treated implants presented a significantly higher (p = .012) new bone formation (72.5% +/- 12.4%; 95% CI 69.6% 86.8%) compared to untreated sites (64.7% +/- 17.3%; 95% CI 59.4%-83.3%). Controversially, no difference (p = .270) in terms of old bone was present between treated (3.1% +/- 1.7%, 95% CI 1.8%-4.2%) and untreated implants (3.8% +/ 1.9%, 95% CI 3.2%-5.8%). Significant differences (p = .018) in terms of total mineralized bone were found between treated (75.6% +/- 13.0%, 95% CI 73.3%-91.3%) and untreated implants (68.4% +/- 16.8%; 95% CI 64.2%-87.6%). CONCLUSIONS: Implants treated using plasma of argon was demonstrated to reach a higher bone-to implant contact when compared to untreated implants. PMID- 29453787 TI - A phase II trial of riluzole, an antagonist of metabotropic glutamate receptor 1 (GRM1) signaling, in patients with advanced melanoma. AB - Studies demonstrate that GRM, expressed by >60% of human melanomas, may be a therapeutic target. We performed a phase II trial of 100 mg PO bid of riluzole, an inhibitor of GRM1 signaling, in patients with advanced melanoma with the primary endpoint of response rate. Thirteen patients with GRM1-positive tumors were enrolled. No objective responses were observed, and accrual was stopped. Stable disease was noted in six (46%) patients, with one patient on study for 42 weeks. Riluzole was well tolerated, with fatigue (62%) as the most common adverse event. Downregulation of MAPK and PI3K/AKT was noted in 33% of paired tumor biopsies. Hypothesis-generating correlative studies suggested that downregulation of angiogenic markers and increased leukocytes at the active edge of tumor correlate with clinical benefit. Pharmacokinetic analysis showed interpatient variability consistent with prior riluzole studies. Future investigations should interrogate mechanisms of biologic activity and advance the development of agents with improved bioavailability.

PMID- 29453789 TI - Psychotic experiences and religiosity: data from the WHO World Mental Health Surveys. AB - OBJECTIVES: Religiosity is often associated with better health outcomes. The aim of the study was to examine associations between psychotic experiences (PEs) and religiosity in a large, cross-national sample. METHODS: A total of 25 542 adult respondents across 18 countries from the WHO World Mental Health Surveys were assessed for PEs, religious affiliation and indices of religiosity, DSM-IV mental disorders and general medical conditions. Logistic regression models were used to estimate the association between PEs and religiosity with various adjustments. RESULTS: Of 25 542 included respondents, 85.6% (SE = 0.3) (n = 21 860) respondents reported having a religious affiliation. Overall, there was no association between religious affiliation status and PEs. Within the subgroup having a religious affiliation, four of five indices of religiosity were significantly associated with increased odds of PEs (odds ratios ranged from 1.3 to 1.9). The findings persisted after adjustments for mental disorders and/or general medical conditions, as well as religious denomination type. There was a significant association between increased religiosity and reporting more types of PEs. CONCLUSIONS: Among individuals with religious affiliations, those who reported more religiosity on four of five indices had increased odds of PEs. Focussed and more qualitative research will be required to unravel the interrelationship between religiosity and PEs. PMID- 29453790 TI - Amyloid-beta 1-40 is associated with alterations in NG2+ pericyte population ex vivo and in vitro. AB - The population of brain pericytes, a cell type important for vessel stability and blood brain barrier function, has recently been shown altered in patients with Alzheimer's disease (AD). The underlying reason for this alteration is not fully understood, but progressive accumulation of the AD characteristic peptide amyloid beta (Abeta) has been suggested as a potential culprit. In the current study, we show reduced number of hippocampal NG2+ pericytes and an association between NG2+ pericyte numbers and Abeta1-40 levels in AD patients. We further demonstrate, using in vitro studies, an aggregation-dependent impact of Abeta1-40 on human NG2+ pericytes. Fibril-EP Abeta1-40 exposure reduced pericyte viability and proliferation and increased caspase 3/7 activity. Monomer Abeta1-40 had quite the opposite effect: increased pericyte viability and proliferation and reduced caspase 3/7 activity. Oligomer-EP Abeta1-40 had no impact on either of the cellular events. Our findings add to the growing number of studies suggesting a significant impact on pericytes in the brains of AD patients and suggest different aggregation forms of Abeta1-40 as potential key regulators of the brain pericyte population size. PMID- 29453792 TI - Impact of TSH during the first trimester of pregnancy on obstetric and foetal complications: Usefulness of 2.5 mIU/L cut-off value. AB - OBJECTIVE: An association of pregnancy outcomes with subclinical hypothyroidism has been reported; however, there still exists a strong controversy regarding whether subclinical hypothyroidism ought to be dealt with or not. The objective of the study was to evaluate the association of foetal-maternal complications with first trimester maternal Thyrotropin (TSH) values. DESIGN: A retrospective study in a single tertiary care hospital was performed. PATIENTS: A total of 1981 pregnant women were studied during 2012. MEASUREMENTS: Thyrotropin (TSH) universal screening was performed between 9 and 12 weeks of gestation. Outcomes included foetal-maternal complications and newborn health parameters. RESULTS: Median TSH was 1.72 (0.99-2.61) mIU/L. The incidence of perinatal loss, miscarriage and stillbirth was 7.2%, 5.9% and 1.1%, respectively. Median TSH of women with and without miscarriage was 1.97 (1.29-3.28) vs 1.71 (0.96-2.58) mIU/L (P = .009). Incidence of pre-eclampsia was 3.2%; TSH in these women was 2.10 (1.40-2.74) vs 1.71 (0.98-2.59) mIU/L in those without (P = .027). TSH in women with dystocia in labour was 1.76 (1.00-2.53) vs 1.68 (0.94-2.59) mIU/L in those who gave birth with normal progression (P = .044). Women with TSH 2.5-5.1 mIU/L had a higher risk of perinatal loss [OR 1.589 (1.085-2.329)], miscarriage [OR 1.702 (1.126-2.572)] and premature birth [OR 1.39 (1.013-1.876)], adjusted by mother's age. There was no association with the other outcomes analysed. CONCLUSIONS: There is a positive association between maternal TSH in the first trimester of pregnancy and the incidence of perinatal loss and miscarriage. The TSH cut-off value of 2.5 mIU/L identified women with higher adverse pregnancy outcomes. PMID- 29453793 TI - Cross-cultural comparison of predictors for self-care behaviors in patients with type 2 diabetes. AB - The aim of the present study was to evaluate how culture moderates the behavioral and psychosocial predictors of diabetes self-care activities. Patients with type 2 diabetes were recruited in the outpatient department at two sites: Kyoto University hospital in Japan and the Christiana Care Health System in the USA. The data were collected by survey using questionnaires including questions on the frequency of self-care activities, behavioral and psychosocial predictors, and other background information from 149 Japanese patients and 48 American patients. The cultural impact was observed by multiple regression analyses with interaction terms on the association between emotional support and self-care activities in diet in female patients. The findings of the present study serve as an example of how cultural context can affect patients with diabetes, and lead to a better understanding of culturally sensitive behavioral intervention.

PMID- 29453795 TI - Inflammatory and degenerative phases resulting from anterior cruciate rupture in a non-invasive murine model of post-traumatic osteoarthritis. AB - Joint injury is the predominant risk factor for post-traumatic osteoarthritis development (PTOA). Several non-invasive mouse models mimicking human PTOA investigate molecular mechanisms of disease development; none have characterized the inflammatory response to this acute traumatic injury. Our aim was to characterize the early inflammatory phase and later degenerative component in our in vivo non-invasive murine model of PTOA induced by anterior cruciate ligament (ACL) rupture. Right knees of 12-week-old C57Bl6 mice were placed in flexion at a 30 degrees offset position and subjected to a single compressive load (12N, 1.4 mm/s) to induce ACL rupture with no obvious damage to surrounding tissues. Tissue was harvested 4 h post-injury and on days 3, 14, and 21; contralateral left knees served as controls. Histological, immunohistochemical, and gene analyzes were performed to evaluate inflammatory and degenerative changes. Immunohistochemistry revealed time-dependent expression of mature (F4/80 positive) and inflammatory (CD11b positive) macrophage populations within the sub-synovial infiltrate, developing osteophytes, and inflammation surrounding the ACL in response to injury. Up-regulation of genes encoding acute pro-inflammatory markers, inducible nitric oxide synthase, interleukin-6 and interleukin-17, and the matrix degrading enzymes, ADAMTS-4 and MMP3 was detected in femoral cartilage, concomitant with extensive cartilage damage and bone remodelling over 21-days post-injury. Our non invasive model describes pathologically distinct phases of the disease, increasing our understanding of inflammatory episodes, the tissues/cells producing inflammatory mediators and the early molecular changes in the joint, thereby defining the early phenotype of PTOA. This knowledge will guide appropriate interventions to delay or arrest disease progression following joint injury. (c) 2018 The Authors.

PMID- 29453796 TI - Using a hospital admission survey to estimate the burden of influenza-associated severe acute respiratory infection in one province of Cambodia-methods used and lessons learned. AB - BACKGROUND: Understanding the burden of influenza-associated severe acute respiratory infection (SARI) is important for setting national influenza surveillance and vaccine priorities. Estimating influenza-associated SARI rates requires hospital-based surveillance data and a population-based denominator, which can be challenging to determine. OBJECTIVES: We present an application of the World Health Organization's recently developed manual (WHO Manual) including hospital admission survey (HAS) methods for estimating the burden of influenza associated SARI, with lessons learned to help others calculate similar estimates. METHODS: Using an existing SARI surveillance platform in Cambodia, we counted influenza-associated SARI cases during 2015 at one sentinel surveillance site in Svay Rieng Province. We applied WHO Manual-derived methods to count respiratory hospitalizations at all hospitals within the catchment area, where 95% of the sentinel site case-patients resided. We used HAS methods to adjust the district level population denominator for the sentinel site and calculated the incidence rate of influenza-associated SARI by dividing the number of influenza-positive SARI infections by the adjusted population denominator and multiplying by 100 000. We extrapolated the rate to the provincial population to derive a case count for 2015. We evaluated data sources, detailed steps of implementation, and identified lessons learned. RESULTS: We estimated an adjusted influenza associated 2015 SARI rate of 13.5/100 000 persons for the catchment area of Svay Rieng Hospital and 77 influenza-associated SARI cases in Svay Rieng Province after extrapolation. CONCLUSIONS: Methods detailed in the WHO Manual and operationalized successfully in Cambodia can be used in other settings to estimate rates of influenza-associated SARI. PMID- 29453797 TI - Quality of partner support moderates positive affect in patients with cancer. AB - OBJECTIVE: In the present study, we examined whether 4 support quality-related characteristics moderate the impact of received partner support on positive affect of patients with cancer. The support quality-related characteristics were patients' perception regarding the willingness of their partners to offer support, patients' perception that partner support is certain, patients' satisfaction with partner relationship, and overall patients' satisfaction with partner support. METHODS: Seventy-seven recently diagnosed patients with cancer were assessed at 2 time points, during chemotherapy treatment (baseline) and 7 months later (follow-up). Two types of received support were examined, emotional support and advice-guidance from partner. Multiple regression analyses were performed to determine the moderating effect of the quality-related variables on the relationship between received support at baseline and patient's positive affect at 7-month follow-up. RESULTS: Results showed that all 4 quality-related characteristics had a moderating role (f2 ranged between .06 and .16, P < .05). Emotional support predicted positive affect only when patients reported high partner willingness to offer support, considered the partner support certain, were satisfied with the partner relationship (a trend), and were satisfied with the received support. In contrast, when patients perceived their partners as unwilling to provide support and were dissatisfied with the relationship, support (both emotional and advice-guidance and advice-guidance, respectively) exhibited a negative impact on positive affect. CONCLUSIONS: The findings suggest that only when the quality of support is high does social support have a positive impact on patients' positive affect.

AB - Deoxynivalenol (DON) is one of the most prevalent fusarium mycotoxins in feedstuff and food. DON causes detrimental effects on human and animal reproductive systems by inducing oxidative stress and apoptosis. However, melatonin is a multifunctional endogenous hormone that plays crucial roles in the development of animal germ cells and embryos as a robust deoxidizer. In this study, we explored the effects of melatonin on the DON exposure mouse oocytes. Our in vitro and in vivo results showed that DON adversely affected mouse oocyte maturation and early embryo cleavage, while melatonin administration ameliorated the toxic effects of DON. DON exposure disrupted the meiotic spindle formation and kinetochore-microtubule attachment, which induced aneuploidy in oocytes. This might be through DON effects on the acetylated tubulin level. Moreover, we found that DON exposure caused the alteration of DNA and histone methylation level, which might affect early embryo cleavage. The toxic effects of DON on oocytes might be through its induction of oxidative stress-mediated early apoptosis, while the treatment with melatonin significantly ameliorated these phenotypes in DON-exposed mouse oocytes. Collectively, our results indicated the protection effects of melatonin against defects induced by DON during mouse oocyte meiotic maturation. PMID- 29453799 TI - Impact of postdiagnostic statin use on ovarian cancer mortality: A systematic review and meta-analysis of observational studies. AB - AIMS: To comprehensively evaluate the association between postdiagnostic statin use and mortality of ovarian cancer (OC) patients. METHODS: Using a comprehensive strategy, multiple databases (Medline, Embase and Web of Science) were systematically searched to identify observational studies that examined the correlation between statin use and OC mortality up to 31 December 2017. The studies were independently reviewed and selected based on predetermined selection criteria. Data were extracted independently and in duplicate. The risk of bias was evaluated with the Newcastle-Ottawa scale. Hazard ratios (HRs) and 95% confidence intervals (CIs) for mortality were summarized with a profile likelihood random effects model. RESULTS: Of 269 studies, eight cohort studies of 19 904 OC patients met the inclusion criteria. Postdiagnostic statin use was inversely associated with all-cause mortality/overall survival (summarized HR = 0.74; 95%CI = 0.63-0.87; I2 = 55%; n = 7) and cancer-specific mortality (summarized HR = 0.87; 95%CI = 0.80-0.95; I2 = 0%; n = 3) of OC patients. These findings were consistent by subgroup analyses stratified by study and patient characteristics as well as adjustments made for potential confounders. A meta regression analysis found no effect of modification by these variables. Of note, similar significant inverse effects were also observed when increasing the intensity (highest vs. lowest) of postdiagnostic statin use (summarized HR = 0.84; 95%CI = 0.74-0.96; I2 = 0%; n = 3). CONCLUSION: Postdiagnostic statin use can improve the survival of patients with OC. Further prospective cohort and randomized controlled trials are warranted to confirm the therapeutic role of statin use on the outcome of OC.

AB - The present work examines regional deposition within the nose for nasal sprays over a large and wide ranging parameter space by using numerical simulation. A set of 7 realistic adult nasal airway geometries was defined based on computed tomography images. Deposition in 6 regions of each nasal airway geometry (the vestibule, valve, anterior turbinate, posterior turbinate, olfactory, and nasopharynx) was determined for varying particle diameter, spray cone angle, spray release direction, particle injection speed, and particle injection location. Penetration of nasal spray particles through the airway geometries represented unintended lung exposure. Penetration was found to be relatively insensitive to injection velocity, but highly sensitive to particle size. Penetration remained at or above 30% for particles exceeding 10 MUm in diameter for several airway geometries studied. Deposition in the turbinates, viewed as desirable for both local and systemic nasal drug delivery, was on average maximized for particles ranging from ~20 to 30 MUm in diameter, and for low to zero injection velocity. Similar values of particle diameter and injection velocity were found to maximize deposition in the olfactory region, a potential target for nose-to-brain drug delivery. However, olfactory deposition was highly variable between airway geometries, with maximum olfactory deposition ranging over 2 orders of magnitude between geometries. This variability is an obstacle to overcome if consistent dosing between subjects is to be achieved for nose-to brain drug delivery. PMID- 29453800 TI - Atomic structures of corkscrew-forming segments of SOD1 reveal varied oligomer conformations. AB - The aggregation cascade of disease-related amyloidogenic proteins, terminating in insoluble amyloid fibrils, involves intermediate oligomeric states. The structural and biochemical details of these oligomers have been largely unknown. Here we report crystal structures of variants of the cytotoxic oligomer-forming segment residues 28-38 of the ALS-linked protein, SOD1. The crystal structures reveal three different architectures: corkscrew oligomeric structure, nontwisting curved sheet structure and a steric zipper proto-filament structure. Our work highlights the polymorphism of the segment 28-38 of SOD1 and identifies the molecular features of amyloidogenic entities. PMID- 29453802 TI - Introduction to the special issue on membrane trafficking in neurons. PMID- 29453803 TI - Competition for nutrients and light: testing advances in resource competition with a natural phytoplankton community. AB - A key challenge in ecology is to understand how nutrients and light affect the biodiversity and community structure of phytoplankton and plant communities. According to resource competition models, ratios of limiting nutrients are major determinants of species composition. At high nutrient levels, however, species interactions may shift to competition for light, which might make nutrient ratios less relevant. The "nutrient-load hypothesis" merges these two perspectives, by extending the classic model of competition for two nutrients to include competition for light. Here, we test five key predictions of the nutrient-load hypothesis using multispecies competition experiments. A marine phytoplankton community sampled from the North Sea was inoculated in laboratory chemostats provided with different nitrogen (N) and phosphorus (P) loads to induce either single resource limitation or co-limitation of N, P, and light. Four of the five predictions were validated by the experiments. In particular, different resource limitations favored the dominance of different species. Increasing nutrient loads caused changes in phytoplankton species composition, even if the N:P ratio of the nutrient loads remained constant, by shifting the species interactions from competition for nutrients to competition for light. In all treatments, small species became dominant whereas larger species were competitively excluded, supporting the common view that small cell size provides a competitive advantage under resource-limited conditions. Contrary to expectation, all treatments led to coexistence of diatoms, cyanobacteria and green algae, resulting in a higher diversity of species than predicted by theory. Because the coexisting species comprised three phyla with different photosynthetic pigments, we speculate that niche differentiation in the light spectrum might play a role. Our results show that mechanistic resource competition models that integrate nutrient-based and light-based approaches provide an important step forward to understand and predict how changing nutrient loads affect community composition. PMID- 29453805 TI - N-Heterocyclic-Carbene-Treated Gold Surfaces in Pentacene Organic Field-Effect Transistors: Improved Stability and Contact at the Interface. AB - N-Heterocyclic carbenes (NHCs), which react with the surface of Au electrodes, have been successfully applied in pentacene transistors. With the application of NHCs, the charge-carrier mobility of pentacene transistors increased by five times, while the contact resistance at the pentacene-Au interface was reduced by 85 %. Even after annealing the NHC-Au electrodes at 200 degrees C for 2 h before pentacene deposition, the charge-carrier mobility of the pentacene transistors did not decrease. The distinguished performance makes NHCs as excellent alternatives to thiols as metal modifiers for the application in organic field effect transistors (OFETs). PMID- 29453804 TI - Probiotics Affect One-Carbon Metabolites and Catecholamines in a Genetic Rat Model of Depression. AB - SCOPE: Probiotics may influence one-carbon (C1) metabolism, neurotransmitters, liver function markers, or behavior. METHODS AND RESULTS: Male adult Flinders Sensitive Line rats (model of depression, FSL; n = 22) received Lactobacillus helveticus R0052 and Bifidobacterium longum R0175 (109 or 1010 colony-forming units per day) or vehicle for 10 weeks. The controls, Flinders Resistant Line rats (FRL, n = 8), only received vehicle. C1-related metabolites were measured in plasma, urine, and different tissues. Monoamine concentrations were measured in plasma, hippocampus, and prefrontal cortex. Vehicle-treated FSL rats had higher plasma concentrations of betaine, choline, and dimethylglycine, but lower plasma homocysteine and liver S-adenosylmethionine (SAM) than FRLs. FSL rats receiving high-dose probiotics had lower plasma betaine and higher liver SAM compared to vehicle-treated FSL rats. FSLs had higher concentrations of norepinephrine, dopamine, and serotonin than FRLs across various brain regions. Probiotics decreased plasma dopamine in FSLs in a dose-dependent manner. There were no detectable changes in liver function markers or behavior. CONCLUSIONS: Probiotics reduced the flow of methyl groups via betaine, increased liver SAM, and decreased plasma dopamine and norepinephrine. Since these changes in methylation and catecholamine pathways are known to be involved in several diseases, future investigation of the effect of probiotics is warranted. PMID- 29453806 TI - CQ sensitizes human pancreatic cancer cells to gemcitabine through the lysosomal apoptotic pathway via reactive oxygen species. AB - As an established anticancer drug, gemcitabine (GEM) is an effective systemic treatment for advanced pancreatic cancer (PC). However, little is known about the potential effectors that may modify tumour cell sensitivity towards GEM. Autophagy, as a physiological cellular mechanism, is involved in both cell survival and cell death. In this study, we found that exposure to GEM induced a significant increase in autophagy in a dose-dependent manner in PANC-1 and BxPC-3 cells. Inhibition of autophagy by chloroquine (CQ) and ATG7 siRNA increased GEM induced cytotoxicity, and CQ was more effective than ATG7 siRNA. Moreover, CQ significantly enhanced GEM-induced apoptosis, while ATG7 siRNA failed to show the similar effect. Subsequently, we identified a potential mechanism of this cooperative interaction by showing that GEM with CQ pretreatment markedly triggered reactive oxygen species (ROS) boost and then increased lysosomal membrane permeability. Consequently, cathepsins released from lysosome into the cytoplasm induced apoptosis. We showed that CQ could enhance PC cells response to GEM in xenograft models. In conclusion, our data showed that CQ sensitized PC cells to GEM through the lysosomal apoptotic pathway via ROS. Thus, CQ as a potential adjuvant to GEM might represent an attractive therapeutic strategy for PC treatment. PMID- 29453807 TI - Tunable poly(methacrylic acid-co-acrylamide) nanoparticles through inverse emulsion polymerization. AB - Environmentally responsive biomaterials have played key roles in the design of biosensors and drug delivery vehicles. Their physical response to external stimuli, such as temperature or pH, can transduce a signal or trigger the release of a drug. In this work, we designed a robust, highly tunable, pH-responsive nanoscale hydrogel system. We present the design and characterization of poly(methacrylic acid-co-acrylamide) hydrogel nanoparticles, crosslinked with methylenebisacrylamide, through inverse emulsion polymerization. The effects of polymerization parameters (i.e., identities and concentrations of monomer and surfactant) and polymer composition (i.e., weight fraction of ionic and crosslinking monomers) on the nanoparticles' bulk and environmentally responsive properties were determined. We generated uniform, spherical nanoparticles which, through modulation of crosslinking, exhibit a volume swelling of 1.77-4.07, relative to the collapsed state in an acidic environment. We believe our system has potential as a base platform for the targeted, injectable delivery of hydrophilic therapeutics. With equal importance, however, we hope that our systematic analysis of the individual impacts of polymerization and purification conditions on nanoparticle composition, morphology, and performance can be used to expedite the development of alternate hydrophilic nanomaterials for a range of biomedical applications.

PMID- 29453808 TI - Three-dimensional printing in congenital heart disease: A systematic review. AB - Three-dimensional (3D) printing has shown great promise in medicine with increasing reports in congenital heart disease (CHD). This systematic review aims to analyse the main clinical applications and accuracy of 3D printing in CHD, as well as to provide an overview of the software tools, time and costs associated with the generation of 3D printed heart models. A search of different databases was conducted to identify studies investigating the application of 3D printing in CHD. Studies based on patient's medical imaging datasets were included for analysis, while reports on in vitro phantom or review articles were excluded from the analysis. A total of 28 studies met selection criteria for inclusion in the review. More than half of the studies were based on isolated case reports with inclusion of 1-12 cases (61%), while 10 studies (36%) focused on the survey of opinion on the usefulness of 3D printing by healthcare professionals, patients, parents of patients and medical students, and the remaining one involved a multicentre study about the clinical value of 3D printed models in surgical planning of CHD. The analysis shows that patient-specific 3D printed models accurately replicate complex cardiac anatomy, improve understanding and knowledge about congenital heart diseases and demonstrate value in preoperative planning and simulation of cardiac or interventional procedures, assist surgical decision making and intra-operative orientation, and improve patient-doctor communication and medical education. The cost of 3D printing ranges from USD 55 to USD 810. This systematic review shows the usefulness of 3D printed models in congenital heart disease with applications ranging from accurate replication of complex cardiac anatomy and pathology to medical education, preoperative planning and simulation. The additional cost and time required to manufacture the 3D printed models represent the limitations which need to be addressed in future studies. PMID- 29453810 TI - A case-control study and meta-analysis reveal the association between COX-2 G 765C polymorphism and primary end-stage hip and knee osteoarthritis. AB - BACKGROUND: Osteoarthritis (OA) is a popular arthrosis featured as pain, limited joint activity, and deformity. Cyclooxygenase-2 (COX-2) has been reported to be up-regulated in arthritic tissues and is integral to the progression of osteoarthritis (OA). Previous studies showed the COX-2 promoter G-765C polymorphism could influence COX-2 expression. However, the relationship between the variant and OA risk is contrasting. METHODS: We conducted a case-control study with 196 primary end-stage hip and knee OA cases and 196 controls in a Chinese Han population. Subsequently, we integrated this case-control study in a meta-analysis to acquire greater statistical power. The results from our case control study using MassARRAY genotyping technology and binary logistic regression statistical methods. RESULTS: The variant carriers in the Chinese Han population had a lower primary end-stage hip and knee OA susceptibility (C vs G: OR = 0.350, 95%CI: 0.154-0.797, P = .012; GC vs GG: adjusted OR = 0.282, 95%CI: 0.118-0.676, P = .005). Stratification studies indicated that a higher GC frequency in women decreased not only knee OA susceptibility but also unilateral knee OA risk. The meta-analysis showed that the variant exhibited a significantly decreased OA risk through comparisons involving allelic, homozygous, heterozygous, and dominant models. CONCLUSION: Our findings suggest that the COX 2 G-765C polymorphism exerts a protective effect against primary end-stage knee osteoarthritis in a female Chinese Han population. PMID- 29453811 TI - Multimodal treatment including tandem high-dose chemotherapy and autologous stem cell transplantation in children with anaplastic ependymomas. AB - In this study, we evaluated the results of multimodal treatment that included tandem HDCT/auto-SCT in children with anaplastic ependymomas. Fourteen patients with anaplastic ependymomas were enrolled from 2006 to 2014. Six cycles of induction chemotherapy were administered to all patients before they underwent tandem HDCT/auto-SCT. Patients who were older than 3 years of age were administered RT after two cycles of induction chemotherapy. In patients under 3 years of age, RT was either omitted or delayed until they reached 3 years of age, if the patients experienced CR after tandem HDCT/auto-SCT. All patients, including two who experienced disease progression during induction treatment, underwent the first HDCT/auto-SCT, and 13 subsequently underwent the second HDCT/auto-SCT. One patient died from hepatic VOD during the second HDCT/auto-SCT; other toxicities occurring during tandem HDCT/auto-SCT were manageable. Relapses or progression occurred in seven patients, and five of seven of them remain alive till date after salvage treatment, including surgery and RT. The 5-year overall and event-free survival rates were 85.1% +/- 9.7% and 50.0% +/- 13.4%, respectively. These findings suggest that multimodal treatment including tandem HDCT/auto-SCT could be a feasible option for improving survival in children with anaplastic ependymomas. PMID- 29453812 TI - Cognitive outcomes in children and adolescents born very preterm: a meta analysis. AB - AIM: To estimate the association between very preterm birth (<32wks' gestation) and intelligence, executive functioning, and processing speed throughout childhood and adolescence, and to examine the effects of gestational age, birthweight, and age at assessment. METHOD: Studies were included if children were born at earlier than 32 weeks' gestation, aged 4 to 17 years, had an age matched term control group, and if the studies used standardized measures, were published in an English-language peer-reviewed journal, and placed no restrictions on participants based on task performance. RESULTS: We evaluated 6163 children born very preterm and 5471 term-born controls from 60 studies. Children born very preterm scored 0.82 SDs (95% confidence interval [CI] 0.74 0.90; p<0.001) lower on intelligence tests, 0.51 SDs (95% CI 0.44-0.58; p<0.001) lower on measures of executive functioning, and 0.49 SDs (95% CI 0.39-0.60; p<0.001) lower on measures of processing speed than term-born controls. Gestational age and birthweight were associated with study effect size in intelligence and executive functioning of younger children only. Age at assessment was not associated with study effect size. INTERPRETATION: Children born very preterm have medium to large deficits in these cognitive domains. WHAT THIS PAPER ADDS: This meta-analysis is centred on very preterm birth and three cognitive domains. The three critical cognitive domains are intelligence, executive functioning, and processing speed. PMID- 29453813 TI - Association between two common transitions of H2BFWT gene and male infertility: a case-control, meta, and structural analysis. AB - H2BFWT is one of the testis-specific histones that plays a fundamental role in spermatogenesis, and single nucleotide polymorphisms (SNPs) in this gene may result in male infertility. This study aimed to investigate the association between -9C>T and 368A>G transitions of H2BFWT gene and male infertility through a case-control, meta-analysis, and a bioinformatics approach. In this case control study, 490 subjects including 240 idiopathic infertile men and 250 healthy controls were included. The -9C>T and 368A>G SNPs genotyping were performed by a PCR-RFLP method. To find eligible studies for meta-analysis, we searched valid scientific databases. The odds ratios with 95% confidence intervals were estimated to find the strength of these associations. Furthermore, the influences of two common transitions on the molecular features of H2BFWT were assessed by in silico tools. Our case-control data revealed that -9C>T is not associated with male infertility. But, there was a significant association between 368A>G and male infertility. In the meta-analysis, five eligible studies were included. Our data revealed significant associations between -9C>T, 368A>G, and male infertility in overall and stratified analyses. Moreover, structural analysis showed that 368A>G could affect the protein structure (SNAP prediction: non-neutral, score: 42, expected accuracy: 71%; SIFT prediction: deleterious, score: -2.55), while -9C>T may affect the binding nucleotide in the promoter region. Based on these findings, two aforementioned polymorphisms were associated with increased risk of male infertility. However, studies with larger sample size and different ethnicities are needed to obtain more accurate conclusions. PMID- 29453814 TI - Preclinical evaluation of a semi-automated and rapid commercial electrophoresis assay for von Willebrand factor multimers. AB - BACKGROUND: The von Willebrand factor (VWF) multimer test is required to correctly subtype qualitative type 2 von Willebrand disease (VWD). The current VWF multimer assays are difficult, nonstandardized, and time-consuming. The purpose of this study was to evaluate the clinical utility of the commercial VWF multimer kit by Sebia (Lisses, France), an electrophoresis technique yielding same-day results. METHODS: Ten healthy volunteer plasma samples, in-house reference plasma (IRP) and commercial normal plasma (CNP) samples, 10 plasma samples from patients with a known VWD type, 1 hemophilia A plasma sample, and 7 external quality assurance (EQA) samples were analyzed using the commercial VWF multimer kit. Additional coagulation testing included measurements of VWF antigen (VWF:Ag), VWF activity (VWF:Ac), and FVIII activity (FVIII:C). RESULTS: The CNP results revealed a relative loss of the highest molecular weight multimers; therefore, IRP was preferred as the reference sample. The interpretations of 10 patients with a known VWD type could be successfully reproduced and agreed with previous VWF multimer results. In all EQA surveys, the multimer results and final VWD diagnosis agreed with expert opinion. CONCLUSIONS: The VWF multimer assay by Sebia is easy to perform and can be successfully implemented in any clinical laboratory for second-stage evaluation of VWD. The resolution power of multimer distribution is adequate to correctly classify VWD types 1, 2A, 2B, and 3. PMID- 29453815 TI - Chitosan porous 3D scaffolds embedded with resolvin D1 to improve in vivo bone healing. AB - The aim of this study was to investigate the effect chitosan (Ch) porous 3D scaffolds embedded with resolvin D1 (RvD1), an endogenous pro-resolving lipid mediator, on bone tissue healing. These scaffolds previous developed by us have demonstrated to have immunomodulatory properties namely in the modulation of the macrophage inflammatory phenotypic profile in an in vivo model of inflammation. Herein, results obtained in an in vivo rat femoral defect model demonstrated that two months after Ch + RvD1 scaffolds implantation, an increase in new bone formation, in bone trabecular thickness, and in collagen type I and Coll I/Coll III ratio were observed. These results suggest that Ch scaffolds embedded with RvD1 were able to lead to the formation of new bone with improvement of trabecular thickness. This study shows that the presence of RvD1 in the acute phase of the inflammatory response to the implanted biomaterial had a positive role in the subsequent bone tissue repair, thus demonstrating the importance of innovative approaches for the control of immune responses to biomedical implants in the design of advanced strategies for regenerative medicine.

AB - Klinefelter syndrome is a frequent cause of hypogonadism, but despite hundreds of publications on different aspects of Klinefelter syndrome, only a few studies dealt with sexual dysfunction. In particular, testosterone is critical for various aspects of sexual response, but its role on sexuality in Klinefelter syndrome patients is debatable and no studies have evaluated the efficacy of testosterone treatment on sexual dysfunction in these subjects. Furthermore, the impact of psychological and relational aspects on sexual function of Klinefelter syndrome subjects is poorly defined. In this study, we aimed to determine the presence and type of sexual dysfunctions in Klinefelter syndrome subjects; to correlate them with testosterone levels and psychosexological and relational domains; and to evaluate the effects of testosterone therapy. We studied 62 non mosaic naive Klinefelter syndrome patients and 60 age-matched controls by means of medical history, psychosexological history, 15-item International Index of Erectile Function questionnaire, endocrine assessment, and dynamic penile color Doppler ultrasound. Twenty-five hypogonadal Klinefelter syndrome patients were studied after 6 months of testosterone replacement therapy. Klinefelter syndrome subjects have reduced 15-item International Index of Erectile Function scores regarding sexual desire, intercourse satisfaction, and overall satisfaction with respect to controls, and these aspects were significantly associated with testosterone levels. Klinefelter syndrome subjects had also higher prevalence of erectile dysfunction, but no relation with testosterone levels was evident. A high prevalence of a range of psychological disturbances was present in Klinefelter syndrome subjects with erectile dysfunction with respect to those without erectile dysfunction. No statistical difference in the prevalence of premature and delayed ejaculation was observed between Klinefelter syndrome and control subjects. Testosterone replacement therapy improved sexual desire, intercourse satisfaction, and overall satisfaction scores, but had no effect on erectile function. Penile color Doppler ultrasound was normal in all subjects. This study shows that sexual dysfunction in Klinefelter syndrome is multifactorial and related only in part to hypogonadism and largely to psychological disturbances. Evaluation and therapy of sexual dysfunction should include a combined andrological and psychosexological approach.

PMID- 29453818 TI - The association between thyroid function and incidence of metabolic syndrome in euthyroid subjects: Tianjin chronic low-grade systemic inflammation and health cohort study. AB - OBJECTIVE: Thyroid hormones (THs) are primarily responsible for the regulation of energy homeostasis and metabolism. However, few prospective studies have assessed the association between THs and metabolic syndrome (MetS) in a general population. We therefore designed a cohort study to examine whether serum TH levels within the reference range are predictive factors for developing MetS in adults. DESIGN: Prospective cohort study. PARTICIPANTS: A prospective study (n = 6119) was performed in Tianjin, China. Participants without a history of MetS were followed up for 1 to 3 years with a median follow-up duration of 2 years. MEASUREMENTS: Serum free triiodothyronine (FT3), free thyroxine (FT4) and thyroid stimulating hormone (TSH) levels were measured by chemiluminescence immunoassay. MetS was defined in accordance with the criteria of the American Heart Association scientific statements of 2009. THs, TSH levels and MetS were assessed yearly during the follow-up. Adjusted Cox proportional hazards regression models were used to assess the associations between FT3, FT4 and TSH quintiles and MetS. RESULTS: The incidence of MetS was 17.7% (96 per 1000 person-years). In the final multivariate models, the hazard ratios (95% confidence interval) for MetS across serum FT3 quintiles were 1.00 (reference), 1.03 (0.84, 1.25), 1.14 (0.94, 1.38), 1.09 (0.90, 1.32) and 1.33 (1.11, 1.61), respectively (P for trend <.01). However, no significant associations between FT4, TSH and MetS were observed. CONCLUSIONS: This population-based prospective cohort study suggests that increased serum FT3 level, rather than FT4 and TSH, is an independent predictor for developing MetS in euthyroid subjects.

PMID- 29453821 TI - Trends and predictors of cesarean birth in Singapore, 2005-2014: A population based cohort study. AB - BACKGROUND: Rates of cesarean birth have continued to rise in many high-income countries. We examined the temporal trends and predictors of cesarean birth in Singapore. METHODS: Linked hospitalization and Birth Registry data were used to examine all live births to Singaporean citizens and permanent residents between January 1, 2005 and December 31, 2014 (n = 342 932 births). We calculated cesarean rates and age-adjusted average annual percent change (AAPC) in those rates and used sequential multivariable regression modeling to assess the contribution of changes in predictors to the change in cesarean rates over time. RESULTS: The overall cesarean rate in Singapore rose from 32.2% in 2005 to 37.4% in 2014. Among singleton, cephalic, term pregnancies, the two major predictions of cesarean were nulliparity and previous cesarean, each accounting for just over one-third of all cesareans. Higher AAPC was observed in nulliparous women of Indian ethnicity (0.74% [95% confidence interval 0.68-0.80]) compared with Chinese (0.62% [0.60-0.65]) or Malay women (0.63% [0.59-0.68]), and in women who delivered in private hospitals (0.62% [0.60-0.64]) compared with those delivered under subsidized care in public hospitals (0.58% [0.52-0.63]). Parity and education had the largest influences on cesarean birth trend (attenuation of AAPC from 0.62% [0.59-0.66] to 0.39% [0.38-0.40] after adjustment). CONCLUSION: Cesarean birth has continued to rise at a steady rate in Singapore. Strategies to curb this temporal increase include avoidance of medically unnecessary primary cesarean and attempts at trial of labor and vaginal delivery among women with a history of prior cesarean. PMID- 29453822 TI - Full-genome sequencing of porcine circovirus 3 field strains from Denmark, Italy and Spain demonstrates a high within-Europe genetic heterogeneity. AB - Porcine circovirus 3 (PCV3) is a new species of the Circovirus genus, which has recently been associated with different clinical syndromes. Its presence has been reported in different countries of North and South America, Asia and recently also Europe (Poland). However, different from the other continents, no European PCV3 sequence is currently available in public databases. There is a strong need of epidemiological data and full-genome sequences from Europe because of its relevance in the understanding of PCV3 molecular epidemiology and control. To fill this lack of information, samples collected in Denmark, Italy and Spain in 2016 and 2017 were screened for PCV3. Of the Danish samples, 36 of 38 the lymph nodes, six of 20 serum samples and two of 20 lung samples tested positive. Similarly, 10 of 29 lungs, 20 of 29 organ pools, six of 33 sera and one of eight nasal swabs tested PCV3 positive in Italy. Fourteen of 94 serum pools from seven of 14 Spanish farms were also positive. Despite the convenience nature of the sampling prevents any precise prevalence estimation, the preliminary screening of the data from three European countries confirmed a rather wide PCV3 distribution in Europe. Furthermore, the analysis of the six obtained complete European PCV3 genomes and their comparison with the public available sequences seems to support a remarkable worldwide PCV3 circulation. These results underline once more the urgency of more extensive epidemiological studies to refine the current knowledge on PCV3 evolution, transmission, spreading patterns and impact on pig health.

AB - Paeoniflorin (PF), extracted from the root of Paeonia lactiflora Pall, exhibits anti-inflammatory properties in several autoimmune diseases. Osteoclast, the only somatic cell with bone resorbing capacity, was the direct cause of bone destruction in rheumatoid arthritis (RA) and its mouse model, collagen-induced arthritis (CIA). The objective of this study was to estimate the effect of PF on CIA mice, and explore the mechanism of PF in bone destruction. We demonstrated that PF treatment significantly ameliorated CIA through inflammatory response inhibition and bone destruction suppression. Furthermore, PF treatment markedly decreased osteoclast number through the altered RANKL/RANK/OPG ratio and inflammatory cytokines profile. Consistently, we found that osteoclast differentiation was significantly inhibited by PF through down-regulation of nuclear factor-kappaB activation in vitro. Moreover, we found that PF suppressed nuclear factor-kappaB activation by decreasing its translocation to the nucleus in osteoclast precursor cells. Taken together, our new findings provide insights into a novel function of PF in osteoclastogenesis and demonstrate that PF would be a new therapeutic modality as a natural agent for RA treatment and other autoimmune conditions with bone erosion. PMID- 29453824 TI - Giving in when feeling less good: Procrastination, action control, and social temptations. AB - Emotion-regulation perspectives on procrastination highlighting the primacy of short-term mood regulation focus mainly on negative affect. Positive affect, however, has received much less attention and has not been considered with respect to social temptations. To address this issue, we examined how trait procrastination was linked to positive and negative affect in the context of social temptations across two prospective studies. Action Control Theory, Personality Systems Interactions Theory, and a mood regulation theory of procrastination served as guiding conceptual frameworks. In Study 1, moderated mediation analyses revealed that low positive affect explained the link between trait procrastination and time spent procrastinating on academic tasks over a 48 hr period in a student sample (N = 142), and this effect was moderated by the presence of social temptations. Parallel results for goal enjoyment assessed at Time 2 were found in Study 2 with a community sample (N = 94) attempting to make intended health behaviour changes over a 6-month period. Our findings indicate that procrastinators are at risk for disengaging from intended tasks when social temptations are present and positive task-related affect is low.

PMID- 29453827 TI - Using niche breadth theory to explain generalization in mutualisms. AB - For a mutualism to remain evolutionarily stable, theory predicts that mutualists should limit their associations to high-quality partners. However, most mutualists either simultaneously or sequentially associate with multiple partners that confer the same type of reward. By viewing mutualisms through the lens of niche breadth evolution, we outline how the environment shapes partner availability and relative quality, and ultimately a focal mutualist's partner breadth. We argue that mutualists that associate with multiple partners may have a selective advantage compared to specialists for many reasons, including sampling, complementarity, and portfolio effects, as well as the possibility that broad partner breadth increases breadth along other niche axes. Furthermore, selection for narrow partner breadth is unlikely to be strong when the environment erodes variation in partner quality, reduces the costs of interacting with low-quality partners, spatially structures partner communities, or decreases the strength of mutualism. Thus, we should not be surprised that most mutualists have broad partner breadth, even if it allows for ineffective partners to persist. PMID- 29453828 TI - Clinical and aesthetic outcomes of immediately placed single-tooth implants with immediate vs. delayed restoration in the anterior maxilla: A retrospective cohort study. AB - OBJECTIVE: To evaluate the impact of the timing of restoration on clinical and aesthetic outcomes following immediate implant placement in the maxillary aesthetic zone. MATERIAL AND METHODS: Forty patients (16 males, 24 females) with a mean age of 50.55 +/- 12.79 years (range 19-74) who had a single maxillary anterior tooth replaced by an immediate implant were included in this study. Twenty patients had their implant restored immediately with a provisional restoration (Group A), while the other 20 patients had a delayed restoration placed after 3-4 months of non-submerged healing (Group B). Clinical parameters and hard-tissue changes were evaluated after a mean follow-up period of 3 years. Aesthetic evaluation was carried out using the Pink Esthetic Score (PES) and the White Esthetic Score (WES). RESULTS: No significant differences were observed in the bone level changes between the two groups: 0.05 +/- 0.65 mm mesially and 0.06 +/- 0.52 mm distally for the immediate group and 0.30 +/- 0.54 mm mesially and 0.21 +/- 0.60 mm distally for the delayed group, respectively. The median PES scores were 11.5 for Group A and 10 for Group B. Mean PES and WES scores did not differ significantly between Groups A and B: PES (11.1 vs. 10.3; p = .16) and WES (8.4 vs. 7.8; p = .16). In terms of individual PES variables, the distal papillae were significantly better in Group A as compared to Group B (p = .006). CONCLUSIONS: Within the limits of this study, timing of restoration seemed to positively affect the aesthetic outcomes of immediately placed implants as evidenced by higher median PES values for the immediate restoration group when compared to the delayed restoration group. Restoration timing had no impact on the individual PES variables, except for the distal papillary height which was superior in the immediate restoration group. PMID- 29453826 TI - Protein Turnover in Aging and Longevity. AB - Progressive loss of proteostasis is a hallmark of aging that is marked by declines in various components of proteostasis machinery, including: autophagy, ubiquitin-mediated degradation, protein synthesis, and others. While declines in proteostasis have historically been observed as changes in these processes, or as bulk changes in the proteome, recent advances in proteomic methodologies have enabled the comprehensive measurement of turnover directly at the level of individual proteins in vivo. These methods, which utilize a combination of stable isotope labeling, mass spectrometry, and specialized software analysis, have now been applied to various studies of aging and longevity. Here we review the role of proteostasis in aging and longevity, with a focus on the proteomic methods available to conduct protein turnover in aging models and the insights these studies have provided thus far. PMID- 29453829 TI - Proposal for new selection criteria considering pre-transplant muscularity and visceral adiposity in living donor liver transplantation. AB - BACKGROUND: The significance of pre-operative body composition has recently attracted much attention in various diseases. However, cut-off values for these parameters remain undetermined, and these factors are not currently included in selection criteria for recipients of living donor liver transplantation (LDLT). METHODS: Using computed tomography of 657 donors for LDLT, skeletal muscle mass, muscle quality, and visceral adiposity were evaluated by using skeletal muscle mass index (SMI), intramuscular adipose tissue content (IMAC), and visceral-to subcutaneous adipose tissue area ratio (VSR). Sex-specific cut-offs for SMI, IMAC, and VSR were determined, and correlations with outcomes after LDLT in 277 recipients were examined with the aim of establishing new selection criteria for LDLT. RESULTS: On the basis of younger donor data, we determined sex-specific cut off values for low SMI, high IMAC, and high VSR (mean +/- 2 standard deviations). Patients with all three factors showed the lowest survival rate after LDLT (1 year survival rate, 41.2%; P < 0.001). On multivariate analysis, low SMI (P = 0.002), high IMAC (P = 0.002), and high VSR (P = 0.001) were identified as independent risk factors for mortality after LDLT. Based on these findings, we have excluded patients showing all three factors (low SMI, high IMAC, and high VSR) as candidates for LDLT since October 2016. CONCLUSIONS: Using cut-off values determined from healthy donors, we have established new selection criteria for LDLT including body composition, which should improve post-transplant outcomes.

PMID- 29453831 TI - Evaluation of a recombinant multiepitope antigen for diagnosis of hepatitis C virus: A lower cost alternative for antigen production. AB - BACKGROUND: The most of the hepatitis C-infected patients remain undiagnosed until they develop severe liver damage or submitted for serological screening. OBJECTIVE: To evaluate a recombinant multiepitope protein for detection of IgG anti-hepatitis C virus. METHOD: A synthetic gene was cloned, expressed in Escherichia coli, and the recombinant protein was purified. Human serum panel consisted of 88 positives (20 HCV genotyped) and 376 negatives for hepatitis C, 6 positives for human acquired immunodeficiency virus, 6 syphilis positives, 6 hepatitis B positives were tested by IgG antihepatitis C virus using the protein by enzyme-linked immunosorbent assay. In addition, 20 positive (all genotyped samples) and 20 negative samples were also tested by immunoblot and dot blot assays. RESULTS: Positive hepatitis C sera were strongly reactive against the protein by immunoblot assay. In the dot blot assay, positive sera were reactive until 1:1000 dilution and there were no false positive results in the hepatitis C negative sera. In the enzyme-linked immunosorbent assay, positive and negative sera had significant discrimination. No cross-reaction was observed in samples positive for syphilis; human acquired immunodeficiency virus and hepatitis B. All 20 genotyped samples were positive by the three methods. CONCLUSION: The multiepitope protein used here has a lower cost compared to production of each antigen separately and could be an alternative for the serological diagnosis of hepatitis C. PMID- 29453832 TI - Living-donor liver transplantation for mild Zellweger spectrum disorder: Up to 17 years follow-up. AB - Mild Zellweger spectrum disorder, also described as Infantile Refsum disease, is attributable to mutations in PEX genes. Its clinical course is characterized by progressive hearing and vision loss, and neurodevelopmental regression. Supportive management is currently considered the standard of care, as no treatment has shown clinical benefits. LT was shown to correct levels of circulating toxic metabolites, partly responsible for chronic neurological impairment. Of three patients having undergone LT for mild ZSD, one died after LT, while the other two displayed significant neurodevelopmental improvement on both the long-term (17 years post-LT) and short-term (9 months post-LT) follow up. We documented a sustained improvement of biochemical functions, with a complete normalization of plasma phytanic, pristanic, and pipecolic acid levels. This was associated with stabilization of hearing and visual functions, and improved neurodevelopmental status, which has enabled the older patient to lead a relatively autonomous lifestyle on the long term. The psychomotor acquisitions have been markedly improved as compared to their affected siblings, who did not undergo LT and exhibited a poor neurological outcome with severe disabilities. We speculate that LT performed before the onset of severe sensorineural defects in mild ZSD enables partial metabolic remission and improved long-term clinical outcomes. PMID- 29453833 TI - Ketamine induces apoptosis in lung adenocarcinoma cells by regulating the expression of CD69. AB - Ketamine, an anesthetic, analgesic, or sedative, is widely used for the treatment of cancer pain. Recently, ketamine has been also reported to be tumor repressor for inhibiting proliferation, invasion, and migration, and inducing apoptosis in many cancers. However, whether ketamine can induce the apoptosis of lung adenocarcinoma (LUAD) and which downstream molecular mediates its function remain largely unknown. A LUAD cell line A549 was incubated with ketamine at 0, 1, 10, and 100 MUmol/L for 24 h. Trypan blue staining was used to detect the cell viability. Flow cytometry (FACS) was applied to evaluate cell apoptosis proportion. The expression of CD69 was quantitated by western blotting. Ketamine induced the A549 cell apoptosis in a concentration-dependent manner. CD69 was downregulated in LUAD patients' cancer tissue compared with the normal tissue. CD69 can be upregulated in ketamine treating A549 cells and induce the A549 cell apoptosis. Rescue experiment showed that downregulation of CD69 significantly blocked the function of ketamine on inducing apoptosis. Taken together, our results demonstrated that ketamine induced LUAD cells apoptosis by upregulating the CD69 expression. This study suggests that the ketamine can be potential drug for LUAD treatment, and the ketamine/CD69 signaling may be the new potential therapeutic target LUAD therapy. PMID- 29453834 TI - Demystifying Evidence-Based Policy Analysis by Revealing Hidden Value-Laden Constraints. AB - Consider any choice that affects some social policy. A decision that considers evidence will, at its heart, contain some kind of explicit or implicit "because" statement: "We are doing X because the evidence says Y." But can evidence ever truly speak for itself, in the sense of being reducible to objective utterances that are either correct or in need of correction? Before answering, consider what you'd prefer. Would you rather receive evidence that was free of any value judgments imposed by human actors, that was laden with value judgments that you agree with, or laden with value judgments that you disagree with? The central assertion of this essay is that, throughout policy analysis but especially in assessments of the costs and benefits of regulating versus encouraging new technologies (cost-benefit analysis, or CBA), the first possibility above is a mirage, and the second and third are self-contradictory. Instead, we are overwhelmingly confronted with a fourth possibility: we receive evidence that appears to be (or is deliberately touted as) value neutral but is suffused with hidden value judgments. In the second part of this essay, entitled "A Guided Tour through Inevitable Value Judgments," I identify in a systematic way approximately sixty-five value judgments that are routinely (in some cases, invariably) made in CBA, but that are kept hidden. For each judgment, I discuss its genesis as it is most commonly invoked in CBA, explain how it is hidden in plain sight, and offer one or more value judgments that could be made instead of or in addition to the conventional one. The alternative judgments highlight the width of the spectrum of reasonable conclusions an analyst could reach merely by substituting other judgments for the ones currently embedded. Bringing hidden value judgments to light is doubly valuable. First, it allows discussion to ensue on a level playing field; instead of conclusory statements about what the evidence says, transparency permits statements taking the form of "when channeled through these value judgments, the evidence says this." Perhaps more importantly, transparency about value judgments permits participants in the discussions to offer interpretations of evidence contingent on there being different value judgments chosen at one or more points in the analysis, interpretations that may suggest that alternative course(s) of action are preferable to the one being championed. PMID- 29453835 TI - Lessons from Environmental Regulation. AB - Much of the most substantive and in-depth experience with formal cost-benefit analysis in the public policy realm has occurred in the context of federal environmental regulation in the United States. This experience has many important lessons to teach in the realm of synthetic biology. Indeed, many of the dangers and pitfalls that arise when decision-makers use formal CBA to evaluate environmental regulation seem likely to arise in the synthetic biology context as well, sometimes in particularly troubling forms. Unfortunately, while in many instances these concerns may well point toward a rejection of formal CBA for synthetic biology, the experience from environmental regulation turns out to be far less helpful in identifying alternative decision-making tools. Because the decisions that arise in the synthetic biology context have a fundamentally different structure from decisions about environmental regulation, the most useful alternatives from that context do not map easily onto this new context. It may well be generally true that in the search for decision-making tools, we should not be looking for a single silver bullet that will work in all public policy realms. Perhaps, instead, different kinds of decision-making call for different tools. This may be true even within the realm of synthetic biology. I am not entirely sure what the "right" tool is for synthetic biology applications, or even whether a "right" tool exists. But at the end of this essay, I offer a few tentative thoughts about why scenario analysis-a strategic planning tool first developed in the context of military planning following World War II-might be one alternative worth considering. PMID- 29453836 TI - CBA and Precaution: Policy-Making about Emerging Technologies. AB - In the technology assessment literature, the leading alternative to CBA-like methods is usually held to be precaution, which is understood in various ways but is always about making decisions under conditions of uncertainty. Under such conditions, proponents of precaution commonly hold, a straightforward tallying of potential outcomes does not seem possible. Since CBA aims to tally up outcomes to determine which outcome would produce the greatest public benefit, precaution begins to look like, not just an alternative to CBA, but an incompatible alternative. Nonetheless, some of the better-known formulations of a precautionary principle expressly call for combining precaution with assessment of costs and benefits. This essay examines the possible intersection of precaution and CBA. It argues that a moderate kind of CBA is a necessary part of a moderate kind of precaution. The existing proposals for integrating CBA and precaution start with an assumption that the integrative task consists in combining decision tools that generate (contrasting) substantive guidance. An alternative approach, explored here, starts with the idea that precaution is not a decision-generating tool. Rather, it is a way of organizing the thinking that leads eventually to substantive conclusions. The appropriate policy response is reached not by applying a principle but by studying the situation-the proposed action and the problem it is meant to address-and developing recommendations tailored to it. What makes the thinking precautionary is that it emphasizes certain questions-about risk, uncertainty, and values-that CBA tends to suppress. So understood, precaution may well slow the science but is not intrinsically opposed to science or innovation. It can be understood, in fact, as continuous with the science because the contextual understanding of the science and the problems it is meant to address would emerge-in part-from a close engagement with the science. PMID- 29453837 TI - Benefit-Cost Analysis and Emerging Technologies. AB - Emerging technologies are, by definition, full of surprises: developments that we cannot fully anticipate and that might have some bad outcomes as well as good ones. This presents a challenge for anyone trying to make forward-looking policy decisions, including those who apply benefit-cost analysis. BCA is now widely known and used, but it is also widely misunderstood-by many of its advocates as well as its detractors. In this essay, I will begin by examining some of the strengths and weaknesses of BCA as a normative science. Yes, "normative science" is an oxymoron, and the incongruity it speaks to is a source of much of the controversy; BCA is an imperfect answer, but often the best available answer, to the question of how a society should go about making collective but not unanimous choices. I also want to take a hard look at the question of what we are evaluating. BCA is designed to weigh government actions, to see whether they are in the public interest; it is not designed to evaluate private actions. But if the government action is to approve a private action that otherwise would be prohibited, then the BCA inevitably must evaluate the latter. From the perspective of a government regulator, it is very tempting to shift the burden of proof onto private innovators-to obligate them to seek permission to proceed, and to demonstrate that their proposed actions have acceptable risks and will produce a net social benefit. But such burden-shifting is not merely an administrative convenience; it has serious economic consequences that need to be examined. PMID- 29453838 TI - From CBA to Precautionary Appraisal: Practical Responses to Intractable Problems. AB - The purpose of this essay is to critically review the design of methods for ethically robust forms of technology appraisal in the regulation of research and innovation in synthetic biology. It will focus, in particular, on the extent to which cost-benefit analysis offers a basis for informing decisions about which technological pathways to pursue and which to discourage. A further goal is to consider what (if anything) the precautionary principle might offer in enabling better decisions. And this, in turn, raises questions about why mention of precaution can excite accusations of unscientific bias or irrational, "anti innovation" extremism. What does the polarized debate tell us about the politics around synthetic biology? In seeking more rigorous, timely, and practical ways to govern these remarkable new technologies, what might we be missing? The sophistication, diversity, and scope of synthetic biology may seem to make it a rather idiosyncratic area for exploring these general issues. It may seem to be a special case, with the bewildering pace of change amplifying the difficulties. But at root, some of the trickiest issues are just specific instances of familiar and long-standing conundrums in the governance of science and technology. The basic challenge is how to weigh up, for a wide range of potential options, the various pros and cons, as viewed from divergent perspectives, and find a way to justify the best course of action on behalf of society as a whole. This is the central problem addressed by a number of techniques in CBA. On the face of it, synthetic biology seems to present just one more application of these well established and self-confident prescriptive methods. But there do emerge several obstinate, even prohibitive, difficulties for CBA. Although they are well acknowledged by the scholarly literature on and around this topic, they are often sidelined in practice. Yet all are central to the case for applying the concept of precaution to a field like synthetic biology. This essay will briefly explore multicriteria mapping, an appraisal method for exploring contrasting perspectives on emerging technologies, as one practical way to address them. The essay focuses on MCM, not because it presents any sort of panacea for appraisal, but because it is illustrative of the concrete implications of precaution. Setting out even just one among potentially many practical alternative methods at least refutes the last-ditch argument that CBA is the only operational choice. PMID- 29453839 TI - Making Policies about Emerging Technologies. AB - Can we make wise policy decisions about still-emerging technologies-decisions that are grounded in facts yet anticipate unknowns and promote the public's preferences and values? There is a widespread feeling that we should try. There also seems to be widespread agreement that the central element in wise decisions is the assessment of benefits and costs, understood as a process that consists, at least in part, in measuring, tallying, and comparing how different outcomes would affect the public interest. But how benefits and costs are best weighed when making decisions about whether to move forward with an emerging technology is not clear. Many commentators feel that the weighing is often inadequate or inappropriate. Those who argue for a "precautionary" approach to the weighing do so precisely because they feel the need for a restraint on the dominant decision making tools and processes for assessing outcomes. This Hastings Center special report examines those tools and processes, taking the method known as cost benefit analysis as a starting point. In U.S. governance, CBA, sometimes informed by risk assessment, is the most widely used and extensively studied method, and authoritative reports on genetic and reproductive technologies often use language suggestive of cost-benefit analysis. There is also a long-running debate about the role of values in CBA and other formal impact assessment mechanisms-and about how those mechanisms compare to the precautionary principle. The guiding idea in the report is to engage in a close examination of the strengths and limits of CBA for ensuring that emerging technologies are used in ways that square with the public's values, drawing on applications of synthetic biology to illustrate and sharpen the analysis and then considering corrections to CBA and some alternative methodologies that handle values differently. PMID- 29453840 TI - About the Special Report. PMID- 29453841 TI - Beyond Cost-Benefit Analysis in the Governance of Synthetic Biology. AB - For many innovations, oversight fits nicely within existing governance mechanisms; nevertheless, others pose unique public health, environmental, and ethical challenges. Synthetic artemisinin, for example, has many precursors in laboratory-developed drugs that emulate natural forms of the same drug. The policy challenges posed by synthetic artemisinin do not differ significantly in kind from other laboratory-formulated drugs. Synthetic biofuels and gene drives, however, fit less clearly into existing governance structures. How many of the new categories of products require new forms of regulatory oversight, or at least extensive forms of testing, remains unclear. Any effort to improve the governance of synthetic biology should start with a rich understanding of the different possible science-policy interfaces that could help to inform governance. CBA falls into a subset of the overall range of possibilities, and which interface is appropriate may turn out to depend on context, on the demands of the decision at hand. In what follows, we lay out a typology of interfaces. After that, we turn to the question of how to draw upon the range of possible interfaces and effectively address the factual and moral complexities of emerging technologies. We propose a governance model built around structures that we call "governance coordinating committees." GCCs are intended to be mechanisms for accommodating the complexities of innovations that have far-ranging societal impacts. The production of biofuels, for example, could contaminate water supplies and have a destructive environmental impact if not managed correctly. The introduction of a gene drive could have economic and environmental impacts that are not restricted to one nation. Forging appropriate means for determining and evaluating those societal impacts, to the best of a corporation's, industry's, or government's ability, is central to responsible research and innovation. Public policy must be shaped in a manner that accommodates as many concerns as possible and minimizes risks. PMID- 29453842 TI - About The Hastings Center. PMID- 29453843 TI - Behavioral Economics and the Public Acceptance of Synthetic Biology. AB - Different applications of synthetic biology are alike in that their possible negative consequences are highly uncertain, potentially catastrophic, and perhaps irreversible; therefore, they are also alike in that public attitudes about them are fertile ground for behavioral economic phenomena. Findings from behavioral economics suggest that people may not respond to such applications according to the normal rules of economic evaluation, by which the value of an outcome is multiplied by the mathematical probability that the outcome will occur. Possibly, then, synthetic biology applications challenge the normative postulates of the standard approach, too. I want to first consider how some of the phenomena described by behavioral economists-and behavioral scientists more broadly-might affect people's perceptions of the uncertainties associated with synthetic biology. My analysis will be far from complete, however, because behavioral economics is essentially the study of human behavior, and thus its reach is potentially vast and its development longstanding and ongoing. Nonetheless, I hope to give an indicative perspective on how some aspects of behavioral economics might affect the assessment and perceived acceptability of synthetic biology. I will then consider the issue of agency. Should policy-makers respect people's reactions to synthetic biology when those reactions are known to be driven by behavioral economic phenomena rather than following the normative postulates of rational choice theory? Or should policy-makers dismiss these reactions as inherently biased? I will argue that the normative force of these human reactions (probably) depends on phenomenon and context. PMID- 29453844 TI - Integrating Scenario Planning and Cost-Benefit Methods. AB - By their nature, the most vexing social problems reflect collisions between social and economic interests of parties with highly divergent views and perspectives on the cause and character of what is at issue and the consequences that flow from it. Conflicts around biotechnology applications are good examples of these problems. When considering the potential consequences of proposed biotechnology applications, an enormous range of perspectives arise reflecting the breadth of different and often competing interests with a stake in life's future. This essay starts from an assumption that the traditional tool of cost benefit analysis is not adequate for adjudicating competing claims around the introduction of new biotechnology applications. It tends to require implicit simplifying assumptions that reduce or mask true underlying levels of complexity and uncertainty, and the results it produces deliver a definitive and singular answer, as opposed to a multiplicity of outcomes. In this essay, I describe some of the key elements of formal scenario planning to show how CBA could be redeployed as a supporting tool within the broader decision support methodology of formal scenario planning. PMID- 29453846 TI - Fabrication of miniature elastomer lenses with programmable liquid mold for smartphone microscopy: curing polydimethylsiloxane with in situ curvature control. AB - Miniature lenses can transform commercial imaging systems, e.g., smartphones and webcams, into powerful, low-cost, handheld microscopes. To date, the reproducible fabrication of polymer lenses is still a challenge as they require controlled dispensing of viscous liquid. This paper reports a reproducible lens fabrication technique using liquid mold with programmable curvature and off-the-shelf materials. The lens curvature is controlled during fabrication by tuning the curvature of an interface of two immiscible liquids [polydimethylsiloxane (PDMS) and glycerol]. The curvature control is implemented using a visual feedback system, which includes a software-based guiding system to produce lenses of desired curvature. The technique allows PDMS lens fabrication of a wide range of sizes and focal lengths, within 20 min. The fabrication of two lens diameters: 1 and 5 mm with focal lengths ranging between 1.2 and 11 mm are demonstrated. The lens surface and bulk quality check performed using X-ray microtomography and atomic force microscopy reveal that the lenses are suitable for optical imaging. Furthermore, a smartphone microscope with ~1.4-MUm resolution is developed using a self-assembly of a single high power fabricated lens and microaperture. The lenses have various potential applications, e.g., optofluidics, diagnostics, forensics, and surveillance.

AB - Bundled fiber optics allow in vivo imaging at deep sites in a body. The intrinsic optical contrast detects detailed structures in blood vessels and organs. We developed a bundled-fiber-coupled endomicroscope, enabling stereoscopic three dimensional (3-D) reflectance imaging with a multipositional illumination scheme. Two illumination sites were attached to obtain reflectance images with left and right illumination. Depth was estimated by the horizontal disparity between the two images under alternative illuminations and was calibrated by the targets with known depths. This depth reconstruction was applied to an animal model to obtain the 3-D structure of blood vessels of the cerebral cortex (Cereb cortex) and preputial gland (Pre gla). The 3-D endomicroscope could be instrumental to microlevel reflectance imaging, improving the precision in subjective depth perception, spatial orientation, and identification of anatomical structures. PMID- 29453848 TI - Postoperative Recurrence of Crohn's Disease: Pathophysiology, Diagnosis and Treatment. AB - BACKGROUND: Abstract: Up to 80% of Crohn's disease (CD) patients require at least one surgical intervention in their lifetime and up to 70% of these patients develop postoperative endoscopic recurrence within 1 year. METHODS: The most important predictors of early postoperative recurrence are represented by smoking, prior intestinal surgery, penetrating disease and perianal location. Genetic factors, gut microbiota structure and immunological alterations may be involved in the pathogenesis of postoperative recurrence of CD, although their specific roles have to be determined yet. RESULTS: Different drugs, such as metronidazole, thiopurines and anti-tumor necrosis factor alpha (anti- TNFalpha) have been shown to reduce the risk of recurrence in many clinical trials, although the choice of the drug should take into consideration the benefits, the potential side effects and also the costs. Patients who are at high risk for postoperative recurrence should be considered for early medical prophylaxis with thiopurines or anti-TNFalpha drugs; on the contrary, patients who do not have risk factors may receive no treatment or receive a course of antibiotic or mesalazine followed by tailored therapy based on endoscopy at 6 months. CONCLUSION: Therefore, stratifying patients according to their risk of recurrence and tailoring therapy are at present the ideal and most cost-effective ways to treat operated CD patients, although many aspects require further evaluation. PMID- 29453849 TI - Methionine is required for cAMP-PKA-mediated morphogenesis and virulence of Candida albicans. AB - Candida albicans is a major human fungal pathogen, causing superficial, as well as life-threatening invasive infections. Therefore, it has to adequately sense and respond to the host defense by expressing appropriate virulence attributes. The most important virulence factor of C. albicans is the yeast-to-hyphae morphogenetic switch, which can be induced by numerous environmental cues, including the amino acid methionine. Here, we show an essential role for methionine permease Mup1 in methionine-induced morphogenesis, biofilm formation, survival inside macrophages and virulence. Furthermore, we demonstrate that this process requires conversion of methionine into S-adenosyl methionine (SAM) and its decarboxylation by Spe2. The resulting amino-propyl group is then used for biosynthesis of polyamines, which have been shown to activate adenylate cyclase. Inhibition of the SPE2 SAM decarboxylase gene strongly impairs methionine-induced morphogenesis on specific media and significantly delays virulence in the mouse systemic infection model system. Further proof of the connection between methionine uptake and initial metabolism and the cAMP-PKA pathway was obtained by showing that both Mup1 and Spe2 are required for cAMP production in response to methionine. Our results suggest that amino acid transport and further metabolism are interesting therapeutic targets as inhibitors of this may prevent the morphogenetic switch, thereby preventing virulence. PMID- 29453850 TI - The role of the immune system in kidney disease. AB - The immune system and the kidneys are closely linked. In health the kidneys contribute to immune homeostasis, while components of the immune system mediate many acute forms of renal disease and play a central role in progression of chronic kidney disease. A dysregulated immune system can have either direct or indirect renal effects. Direct immune-mediated kidney diseases are usually a consequence of autoantibodies directed against a constituent renal antigen, such as collagen IV in anti-glomerular basement membrane disease. Indirect immune mediated renal disease often follows systemic autoimmunity with immune complex formation, but can also be due to uncontrolled activation of the complement pathways. Although the range of mechanisms of immune dysregulation leading to renal disease is broad, the pathways leading to injury are similar. Loss of immune homeostasis in renal disease results in perpetual immune cell recruitment and worsening damage to the kidney. Uncoordinated attempts at tissue repair, after immune-mediated disease or non-immune mediated injury, result in fibrosis of structures important for renal function, leading eventually to kidney failure. As renal disease often manifests clinically only when substantial damage has already occurred, new diagnostic methods and indeed treatments must be identified to inhibit further progression and promote appropriate tissue repair. Studying cases in which immune homeostasis is re-established may reveal new treatment possibilities. PMID- 29453851 TI - Dicer inactivation stimulates limb regeneration ability in Xenopus laevis. AB - The ontogenetic decline of regeneration capacity in the anuran amphibian Xenopus makes it an excellent model for regeneration studies. However, the cause of the regeneration ability decline is not fully understood. MicroRNAs regulate animal development and have been indicated in various regeneration situations. However, little is known about the role of microRNAs during limb regeneration in Xenopus. This study investigates the effect of Dicer, an enzyme responsible for microRNA maturation, on limb development and regeneration in Xenopus. Dicer is expressed in the developing Xenopus limbs and is up-regulated after limb amputation during both regeneration-competent and regeneration-deficient stages of tadpole development. Inactivation of Dicer in early (NF stage 53) tadpole limb buds leads to shorter tibulare/fibulare formation but does not affect limb regeneration. However, in late-stage, regeneration-deficient tadpole limbs (NF stage 57), Dicer inactivation restores the regeneration blastema and stimulates limb regeneration. Thus, our results demonstrated that Xenopus limb regeneration can be stimulated by the inactivation of Dicer in nonregenerating tadpoles, indicating that microRNAs present in late-stage tadpole limbs may be involved in the ontogenetic decline of limb regeneration in Xenopus. PMID- 29453852 TI - A Sulfonozanamivir Analogue Has Potent Anti-influenza Virus Activity. AB - Influenza virus infection continues to cause significant, often severe, respiratory illness worldwide. A validated target for the development of anti influenza agents is the virus surface protein sialidase. In the current study, we have discovered a highly potent inhibitor of influenza virus sialidase, based on a novel sialosyl sulfonate template. The synthesised 3-guanidino sialosyl alpha sulfonate, a sulfonozanamivir analogue, inhibits viral replication in vitro at the nanomolar level, comparable to that of the anti-influenza drug zanamivir. Using protein X-ray crystallography we show that the sialosyl alpha-sulfonate template binds within the sialidase active site in a 1 C4 chair conformation. The C1-sulfonate moiety forms crucial and strong-binding interactions with the active site's triarginyl cluster, while the 3-guanidino moiety interacts significantly with conserved active site residues. This sulfonozanamivir analogue provides a new direction in anti-influenza virus drug development. PMID- 29453854 TI - Cost-effective innovations in low-resource settings. PMID- 29453853 TI - Role of bi-weekly serum galactomannan screening for the diagnosis of invasive aspergillosis in haematological cancer patients. AB - Invasive aspergillosis (IA) is a life-threatening infection affecting haematological cancer patients with chemotherapy-induced neutropenia. The diagnosis of IA often relies on the detection of galactomannan (GM) in serum or bronchoalveolar lavage fluid (BAL). Bi-weekly serum GM screening has been proposed for a pre-emptive therapeutic approach of IA in patients not receiving mold-active prophylaxis. We have analysed all IA cases among patients with haematological malignancies and prolonged chemotherapy-induced neutropenia (>14 days) in our institution over a 10-year period (2007-2017). Serum GM was measured twice weekly and mold-active prophylaxis was not routinely administered. Thirty IA cases were observed and a positive serum GM was the first indicator of IA in 10 (33%) of them, which represents a need of approximately 500 GM tests for the detection of a single IA case. In the other 20 (67%) cases, suggestive chest CT lesion was the first sign of IA and bronchoscopy was required in 15 (50%) cases with negative serum GM for establishing the diagnosis of probable/proven IA. A positive serum GM was associated with a worse prognosis (57% 12-week survival vs 100% among serum GM-negative patients, P = .006), irrespective of the timing of GM positivity compared to CT. We concluded that bi-weekly serum GM screening demonstrated limited benefit in this population. PMID- 29453855 TI - Nerve reinnervation and itch behavior in a rat burn wound model. AB - In this study, we investigated whether postburn itch in rats, after a full thickness burn, is correlated to the nervous reinnervation of the burn wound area. For this purpose, we determined scratching duration (expressed as second/hour) at 24 hours, 2, 4, 8, and 12 weeks postburn and combined this with immunohistochemistry for protein gene product 9.5 (PGP9.5) to identify all nerve fibers, calcitonin gene related peptide (CGRP) to identify peptidergic fibers, tyrosine hydroxylase (TH) for sympathetic fibers, and growth-associated protein 43 (GAP-43) for regrowing fibers. We found a modest, but highly significant, increase in scratching duration of all burn wound rats from 3 to 12 weeks postburn (maximally 63 +/- 9.5 second/hour compared to sham 3.1 +/- 1.4 second/hour at 9 weeks). At 24 hours postburn, all nerve fibers had disappeared from the burn area. Around 4 weeks postburn PGP 9.5- and CGRP-immunoreactive nerve fibers returned to control levels. TH- and GAP-43-IR nerve fibers, which we found to be almost completely colocalized, did not regrow. No correlation was found between scratching duration and nervous reinnervation of the skin. The present results suggest that in rat, like in human, burn wound healing will induce increased scratching, which is not correlated to the appearance of nervous reinnervation. PMID- 29453856 TI - Defective RNA sensing by RIG-I in severe influenza virus infection. AB - Influenza virus infection causes worldwide seasonal epidemics. Although influenza is usually a mild disease, a minority of patients experience very severe fulminating disease courses. Previous studies have demonstrated a role for type I interferon (IFN) in anti-viral responses during influenza. So far, however, IFN regulatory factor (IRF)7 deficiency is the only genetic cause of severe influenza described in humans. In this study we present a patient with severe influenza A virus (IAV) H1N1 infection during the 2009 swine flu pandemic. By whole exome sequencing we identified two variants, p.R71H and p.P885S, located in the caspase activation and recruitment domain (CARD) and RNA binding domains, respectively, of DExD/H-box helicase 58 (DDX58) encoding the RNA sensor retinoic acid inducible gene 1 (RIG-I). These variants significantly impair the signalling activity of RIG-I. Similarly, patient cells demonstrate decreased antiviral responses to RIG I ligands as well as increased proinflammatory responses to IAV, suggesting dysregulation of the innate immune response with increased immunopathology. We suggest that these RIG-I variants may have contributed to severe influenza in this patient and advocate that RIG-I variants should be sought in future studies of genetic factors influencing single-stranded RNA virus infections. PMID- 29453857 TI - Psychosocial student functioning in comprehensive dental clinic education: A qualitative study. AB - INTRODUCTION: The aims were to describe first-year clinical dental students' psychosocial experiences in a known well-functioning comprehensive clinic teaching group (F+Grp) and a known dysfunctional group (Dys-Grp) and, thus, discover and describe phenomena related to psychosocial functioning of students. These groups were compared and contrasted regarding negative stress symptoms, perfectionism and coping with stress. METHODS: Eight female dental students (mean 26 years old), four in each group, were interviewed after the first clinical year about learning and emotional experiences. The students also rated their perceived stress using a 0-10 scale, where 0 is no stress, and 10 is highest stress. Qualitative analyses involved searching for recurring themes and discovery of categories of clinical and social functioning. All 8 students were revisited as dentists after 8 years and filled out a 15-item survey as longitudinal validation of their first-year clinical experiences and to estimate group consensus and informant accuracy. RESULTS: Both groups suffered from negative stress symptoms attributed to lack of time for clinical tasks, worries about work quality with confusion about their own expectations and worries about how others perceived them. Dys-Grp experienced higher negative stress and maladaptive perfectionism and described crying behaviours, withdrawal and unwillingness to cooperate with others. In contrast, students in F+Grp provided rich content about mutual cooperation related to social networking and positive support. The 8 subjects exhibited high internal consistency (alpha = .98) in their responses to the follow-up survey about their first year of clinic. CONCLUSIONS: The comprehensive care teaching clinic environment with students working in groups appeared to provide a possibility for students to support each other for improved stress coping. Unfortunately, the opposite also occurred. Positive, supportive teacher supervision of student challenges related to perfectionism and stress is crucial and requires specific attention.

PMID- 29453859 TI - Diminished CXCR5 expression in peripheral blood of patients with Sjogren's syndrome may relate to both genotype and salivary gland homing. AB - Genetic investigations of Sjogren's syndrome (SS) have identified a susceptibility locus at p23.3 of chromosome 11, which contains the CXCR5 gene. C X-C motif chemokine receptor 5 (CXCR5) is a chemokine receptor expressed on B and T cell subsets, and binds the chemotactic ligand C-X-C motif chemokine ligand 13 (CXCL13). In this study we aimed to link the genetic association with functional effects and explore the CXCR5/CXCL13 axis in SS. Expression quantitative trait loci analysis of the 11q23.3 locus was performed using B cell mRNA expression data from genotyped individuals. Lymphocyte surface markers were assessed by flow cytometry, and CXCL13 levels by a proximity extension assay. CXCR5+ and CXCL13+ cells in minor salivary glands were detected using immunohistochemistry. Our results demonstrated that SS-associated genetic polymorphisms affected the expression of CXCR5 (P < 0.01). Notably, a decreased percentage of CXCR5+ cells, with lower CXCR5 expression, was observed for most circulating B and T cell subsets in SS patients, reaching statistical significance in CD19+ CD27+ immunoglobulin (Ig)D+ marginal zone (P < 0.001), CD19+ CD27+ IgD- memory (P < 0.05) and CD27-IgD double-negative (P < 0.01) B cells and CD4+ CXCR3- CCR6+ Th17 cells (P < 0.05). CXCL13 levels were increased in patient plasma (P < 0.001), and immunohistochemical staining revealed expression of CXCL13 and higher numbers of CXCR5+ cells (P < 0.0001) within focal infiltrates and interstitially in salivary glands of SS patients. In conclusion, we link a genetic susceptibility allele for SS to a functional phenotype in terms of decreased CXCR5 expression. The decrease of CXCR5+ cells in circulation was also related to homing of B and T cells to the autoimmune target organ. Therapeutic drugs targeting the CXCR5/CXCL13 axis may be useful in SS. PMID- 29453861 TI - Virus-Like Particle Engineering: From Rational Design to Versatile Applications. AB - As mimicking natural virus structures, virus-like particles (VLPs) have evolved to become a widely accepted technology used for humans which are safe, highly efficacious, and profitable. Several remarkable advantages have been achieved to revolutionize the molecule delivery for diverse applications in nanotechnology, biotechnology, and medicine. Here, the rational structure design, manufacturing process, functionalization strategy, and emerging applications of VLPs is reviewed. The situation and challenges in the VLP engineering, the key development orientation, and future applications have been discussed. To develop a good VLP design concept, the virus/VLP-host interactions need to be examined and the screening methods of the VLP stabilization factors need to be established. The functionalization toolbox can be expanded to fabricate smart, robust, and multifunctional VLPs. Novel robust VLP manufacturing platforms are required to deliver vaccines in resource-poor regions with a significant reduction in the production time and cost. The future applications of VLPs are always driven by the development of emerging technologies and new requirements of modern life. PMID- 29453860 TI - Fungal infections in patients with inflammatory bowel disease: A systematic review. AB - BACKGROUND: Despite reports of fungal infections in patients with inflammatory bowel disease (IBD), their clinical and microbiological characteristics remain unknown. OBJECTIVES: The aim of this systematic review was to examine all available evidence regarding fungal infections in patients with IBD. METHODS: Systematic search of PubMed (through 27 May 2017) for studies providing data on clinical, microbiological, treatment and outcome data of fungal infections in patients with IBD. The primary study outcome was to record the most common fungal species in patients with IBD. Secondary outcomes were classified into 3 categories: (i) characteristics of fungal infections; (ii) data on IBD and (iii) treatment and outcomes of fungal infections in patients with IBD. RESULTS: Fourteen studies with data on 1524 patients were included in final analysis. The most common fungal infections in patients with IBD were caused by Candida species (903 infections); the most commonly reported site of Candida infection was the gastrointestinal tract. Available evidence shows that most fungal infections occur within 12 months of IBD treatment and within 6 months when anti-TNFa agents are used. CONCLUSIONS: This systematic review thoroughly describes fungal infections in patients with IBD and provides important information for the early detection and management of these infections. PMID- 29453862 TI - Insights into transcriptional silencing and anti-silencing in Shigella flexneri: a detailed molecular analysis of the icsP virulence locus. AB - Transcriptional silencing and anti-silencing mechanisms modulate bacterial physiology and virulence in many human pathogens. In Shigella species, many virulence plasmid genes are silenced by the histone-like nucleoid structuring protein H-NS and anti-silenced by the virulence gene regulator VirB. Despite the key role that these regulatory proteins play in Shigella virulence, their mechanisms of transcriptional control remain poorly understood. Here, we characterize the regulatory elements and their relative spacing requirements needed for the transcriptional silencing and anti-silencing of icsP, a locus that requires remotely located regulatory elements for both types of transcriptional control. Our findings highlight the flexibility of the regulatory elements' positions with respect to each other, and yet, a molecular roadblock docked between the VirB binding site and the upstream H-NS binding region abolishes transcriptional anti-silencing by VirB, providing insight into transcriptional anti-silencing. Our study also raises the need to re-evaluate the currently proposed VirB binding site. Models of transcriptional silencing and anti silencing at this genetic locus are presented, and the implications for understanding these regulatory mechanisms in bacteria are discussed. PMID- 29453863 TI - Aeromonas hydrophila from marketed mullet (Mugil cephalus) in Egypt: PCR characterization of beta-lactam resistance and virulence genes. AB - AIMS: Aeromonas hydrophila has been isolated from various fish species in Egypt and is known to carry virulence and antimicrobial resistance genes, which pose a risk for public health. The aim of the present study is to report, for the first time, the infection of mullet (Mugil cephalus) with A. hydrophila and to clarify the potential association between antimicrobial resistance and virulence traits encoded in A. hydrophila. METHODS AND RESULTS: In this study, the occurrence of A. hydrophila in marketed mullet and the antimicrobial resistance phenotypes of these isolates were determined. Aeromonas hydrophila isolates were screened for the presence of virulence and beta-lactam resistance genes; the correlation between both gene groups was also investigated. The infection rate of examined mullet with A. hydrophila was 37% (50/135). The highest antimicrobial resistance was detected to cefoxitin (100%), followed by ampicillin (84%), ceftazidime (56%) and cefotaxime (40%). Only 4% of the isolates were resistant to erythromycin; 6% were resistant to both gentamicin and kanamycin with no resistance to ciprofloxacin. Variable frequencies of virulence and beta-lactam resistance genes were evident from PCR, where aerA and blaTEM predominated. The study also indicated a general weak positive correlation (R = 0.3) between both virulence and beta-lactam resistance genes. Some of the studied virulence genes (e.g. aerA:hlyA and hlyA:ast) were found to correlate positively. CONCLUSIONS: The presence of virulence and resistance genes in A. hydrophila from food sources poses a serious threat to public health. To our knowledge, this is the first report describing the occurrence of A. hydrophila in mullet and highlighting the coexistence of virulence and beta-lactam resistance genes encoded by these bacteria. SIGNIFICANCE AND IMPACT OF THE STUDY: These data provide insights into the potential association of antimicrobial resistance and virulence genes in A. hydrophila from marketed mullet in Egypt, which could pose threats to humans even if a weak positive correlation exists between both genes.

PMID- 29453864 TI - LPCAT1 controls phosphate homeostasis in a zinc-dependent manner. AB - All living organisms require a variety of essential elements for their basic biological functions. While the homeostasis of nutrients is highly intertwined, the molecular and genetic mechanisms of these dependencies remain poorly understood. Here, we report a discovery of a molecular pathway that controls phosphate (Pi) accumulation in plants under Zn deficiency. Using genome-wide association studies, we first identified allelic variation of the Lyso PhosphatidylCholine (PC) AcylTransferase 1 (LPCAT1) gene as the key determinant of shoot Pi accumulation under Zn deficiency. We then show that regulatory variation at the LPCAT1 locus contributes significantly to this natural variation and we further demonstrate that the regulation of LPCAT1 expression involves bZIP23 TF, for which we identified a new binding site sequence. Finally, we show that in Zn deficient conditions loss of function of LPCAT1 increases the phospholipid Lyso-PhosphatidylCholine/PhosphatidylCholine ratio, the expression of the Pi transporter PHT1;1, and that this leads to shoot Pi accumulation.

PMID- 29453868 TI - Coexistent Solid Malignancies in Pemphigus: A Population-Based Study. AB - Importance: The association of pemphigus vulgaris and pemphigus foliaceus with comorbid malignancies is yet to be firmly established. Objective: To estimate the association between pemphigus and a wide range of nonhematologic malignancies using one of the largest cohorts of patients with pemphigus to date. Design, Setting, and Participants: For this cross-sectional study, we used the computerized database of Clalit Health Services, the largest public health care provider organization in Israel insuring 4.4 million individuals in the settings of general community clinics, primary care and referral centers, and ambulatory and hospitalized health care. The study included 1985 patients with pemphigus and 9874 control patients and was conducted from January 2004 to December 2014. Main Outcomes and Measures: The prevalence of 17 different solid malignancies was compared between patients diagnosed with pemphigus and age-, sex-, and ethnicity matched control patients; chi2 and t tests were used for univariate analysis, and a logistic regression model was used for multivariate analysis. The association was examined following a sensitivity analysis that included only cases treated with long-term pemphigus-specific medications (corticosteroids, immunosuppressants, or rituximab), and following the adjustment for several confounding factors. Results: Overall, the total sample included 11 859 eligible patients, of whom 1985 were patients with pemphigus (mean [SD] age at presentation, 72.1 [18.5] years; 1188 women [59.8%]). In patients with pemphigus compared with control patients, there was a greater prevalence of esophageal cancers (0.4% vs 0.1%; odds ratio [OR], 2.9; 95% CI, 1.1-7.4) and laryngeal cancers (0.6% vs 0.3%; OR, 2.0; 95% CI, 1.0-4.1). No significant associations between pemphigus and other solid malignancies were observed. Estimates were not altered significantly after controlling for comorbidities, health care overutilization, immunosuppressive therapy, and other malignancy-specific risk factors (ie, smoking and alcohol abuse in laryngeal cancer, gastroesophageal reflux disease in esophageal cancer). Conclusions and Relevance: Significant associations were observed between pemphigus and solid malignancies of the larynx and the esophagus. Physicians treating patients with pemphigus should be aware of these findings. Further observational studies are warranted to establish this association in other cohorts.

PMID- 29453871 TI - Examining the Incidence and Presentation of Melanoma in the Cardiothoracic Transplant Population. AB - Importance: The immunosuppression vital to maintaining transplanted organs comes with an increased incidence of cutaneous neoplasms. Understanding the genesis of malignant melanoma (MM) in transplant subpopulations is necessary for adequate disease surveillance. Objective: To determine the incidence and timing of presentation of MM in the cardiothoracic (heart and/or lung) transplant (CTT) population. Design, Setting, and Participants: This was a retrospective cohort study of 1164 patients who underwent a CTT from 2001 through 2016 with a median follow-up time of 4.3 years. The study was performed at a single academic, tertiary referral center. The retrospective database was used to identify 1164 patients who underwent a CTT at Duke University Hospital from 2001 to 2016. Ten patients were excluded from the study owing to a history of MM, resulting in 1154 patients in the study. Five patients who developed MM after CTT were identified. Exposures: Exposures included tacrolimus, prednisone, and mycophenolate mofetil. Main Outcomes and Measures: The primary outcome measurement was the MM incidence. Secondary outcomes included time to diagnosis and survival. Results: Five of 1154 patients who underwent a CTT (0.4%) developed biopsy-proven MM at a median follow up time of 4.3 years after transplantation at a median age of 64.5 years (range, 31.0-74.0 years). Of the 1154 patients, 923 (80%) were men. Their mean (SD) age range was 63.8 years (27.2-68.2 years). Four patients (80%) presented with stage I disease while 1 (20%) presented with stage IV disease at a median time of 2.5 years (range, 0.1-5.3 years) after transplant compared with a median time of 6.2 years (range, 0.9-8.7 years) in Duke University's renal transplant population at a median follow-up time of 6.6 years. Two patients died after transplant, 1 owing to complications of the transplant and 1 owing to metastatic MM. Conclusions and Relevance: Representing one of the largest reported studies of patients with CTT developing MM, our findings suggest that the CTT population experiences an incidence of MM similar to that of other solid organ transplant recipients and with a median of 2.5 years from transplant to melanoma diagnosis. While the small scale of our study prevents far-reaching conclusions, further study is warranted to better understand the incidence, timing, and clinical ramifications of melanomagenesis in the CTT population. PMID- 29453872 TI - Effect of Dermatology Consultation on Outcomes for Patients With Presumed Cellulitis: A Randomized Clinical Trial. AB - Importance: Each year, cellulitis leads to 650 000 hospital admissions and is estimated to cost $3.7 billion in the United States. Previous literature has demonstrated a high misdiagnosis rate for cellulitis, which results in unnecessary antibiotic use and health care cost. Objective: To determine whether dermatologic consultation decreases duration of hospital stay or intravenous antibiotic treatment duration in patients with cellulitis. Design, Setting, and Participants: This randomized clinical trial was conducted in a large urban tertiary care hospital between October 2012 and January 2017, with 1-month follow up duration. Patients were randomized to the control group, which received the standard of care (ie, treatment by primary medicine team), or the intervention group, which received dermatology consultation. Medical chart review of demographic information and hospital courses was performed. Adult patients hospitalized with presumed diagnosis of cellulitis were eligible. A total of 1300 patients were screened, 1125 were excluded, and 175 were included. Statistical analysis was employed to identify significant outcome differences between the 2 groups. Interventions: Dermatology consultation within 24 hours of hospitalization. Main Outcomes and Measures: Length of hospital stay and duration of intravenous antibiotic treatment. Results: Of 175 participants, 70 (40%) were women and 105 (60%) were men. The mean age was 58.8 years. Length of hospital stay was not statistically different between the 2 groups. The duration of intravenous antibiotic treatment (<4 days: 86.4% vs 72.5%; absolute difference, 13.9%; 95% CI, 1.9%-25.9%; P = .04) and duration of total antibiotic treatment was significantly lower in patients who had early dermatology consultation (<10 days: 50.6% vs 32.5%; absolute difference, 18.1%; 95% CI, 3.7%-32.5%; P = .01). Clinical improvement at 2 weeks was significantly higher for those in the intervention group (79 [89.3%] vs 59 [68.3%]; absolute difference, 21.0%; 95% CI, 9.3%-32.7%; P < .001). There was no significant difference in 1-month readmission rate between the groups (4 [4.5%] vs 6 [6.9%]; absolute difference, -2.4%; 95% CI, -9.3% to 4.5%; P = .54). In the intervention group, the rate of cellulitis misdiagnosis was 30.7% (27 of 88 participants). Among the entire cohort, 101 (57.7%) patients were treated with courses of antibiotics longer than what is recommended by guidelines. Conclusions and Relevance: Early dermatologic consultation can improve outcomes in patients with suspected cellulitis by identifying alternate diagnoses, treating modifiable risk factors, and decreasing length of antibiotic treatment. Trial Registration: clinicaltrials.gov Identifier: NCT01706913. PMID- 29453873 TI - Association Between Pemphigus and Neurologic Diseases. AB - Importance: The association between pemphigus and neurologic diseases was not evaluated systematically in the past. In a recent uncontrolled cross-sectional study, Parkinson disease was found to be significantly associated with pemphigus; in the same study, epilepsy had a nonsignificant association with pemphigus. Several case reports have suggested that pemphigus coexists with multiple sclerosis and dementia. Objective: To estimate the association between pemphigus and 4 neurologic conditions (dementia, epilepsy, Parkinson disease, and multiple sclerosis), using one of the largest cohorts of patients with pemphigus. Design, Setting, and Participants: A retrospective population-based cross-sectional study was performed between January 1, 2004, and December 31, 2014, using the database of Clalit Health Services, the largest public health care organization in Israel, in the setting of general community clinics, primary care and referral centers, and ambulatory and hospitalized care. A total of 1985 patients with a new diagnosis of pemphigus and 9874 controls were included in the study. Main Outcomes and Measures: The proportion of dementia, epilepsy, Parkinson disease, and multiple sclerosis was compared between patients diagnosed with pemphigus and age-, sex-, and ethnicity-matched control participants. Logistic regression was used to calculate odds ratios (ORs) for dementia, epilepsy, Parkinson disease, and multiple sclerosis. The association was examined after a sensitivity analysis that included only patients treated with long-term, pemphigus-specific medications (corticosteroids, immunosuppressants, or rituximab) and after adjustment for several confounding factors. Results: When comparing the 1985 cases (1188 women and 797 men; mean [SD] age, 72.1 [18.5] years) with the 9874 controls (5912 women and 3962 men; mean [SD] age, 72.1 [18.5] years), dementia was seen in 622 cases (31.3%) vs 1856 controls (18.8%), with an OR of 1.97 (95% CI, 1.77-2.20). Epilepsy was present in 74 cases (3.7%) vs 210 controls (2.1%), with an OR of 1.78 (95% CI, 1.36-2.33). Parkinson disease was seen in 175 cases (8.8%) vs 437 controls (4.4%), with an OR of 2.09 (95% CI, 1.74-2.51). Multiple sclerosis was present in 2 cases (0.1%) vs 6 controls (0.01%), with an OR of 1.65 (95% CI, 0.34-8.22). Study findings were robust to sensitivity analysis that included patients receiving pemphigus-specific treatments. Estimates were not altered significantly after controlling for comorbidities and overuse of health care. Conclusions and Relevance: An association was observed between pemphigus and specific neurologic diseases, including dementia, Parkinson disease, and epilepsy. Physicians treating patients with pemphigus should be aware of this possible association. Patients with pemphigus should be carefully assessed for comorbid neurologic disorders and receive appropriate treatment. PMID- 29453875 TI - Structural snapshots along the reaction mechanism of the atypical poplar thioredoxin-like2.1. AB - Plastidial thioredoxin (TRX)-like2.1 proteins are atypical thioredoxins possessing a WCRKC active site signature and using glutathione for recycling. To obtain structural information supporting the peculiar catalytic mechanisms and target proteins of these TRXs, we solved the crystal structures of poplar TRX like2.1 in oxidized and reduced states and of mutated variants. These structures share similar folding with TRXs exhibiting the canonical WCGPC signature. Moreover, the overall conformation is not altered by reduction of the catalytic disulfide bond or in a C45S/C67S variant that formed a disulfide-bridged dimer possibly mimicking reaction intermediates with target proteins. Modeling of the interaction of TRX-like2.1 with both NADPH- and ferredoxin-thioredoxin reductases (FTR) indicates that the presence of Arg43 and Lys44 residues likely precludes reduction by the plastidial FTR. PMID- 29453874 TI - Outcomes of Early Dermatology Consultation for Inpatients Diagnosed With Cellulitis. AB - Importance: Many inflammatory skin dermatoses mimic cellulitis (pseudocellulitis) and are treated with antibiotics and/or hospitalization, leading to unnecessary patient morbidity and substantial health care spending. Objective: To evaluate the impact of early dermatology consultation on clinical and economic outcomes associated with misdiagnosed cellulitis. Design, Setting, and Participants: This prospective cohort study enrolled patients with presumed diagnosis of cellulitis in the emergency department, in the emergency department observation unit, or within 24 hours of admission to an inpatient unit of a large urban teaching hospital between February and September 2017. Patients were provided with telephone and clinic follow-up during the 30-day postdischarge period. We screened 165 patients with the primary concern of cellulitis. Of these, we excluded 44 who required antibiotics for cutaneous, soft-tissue, and deeper tissue and/or bone infections irrespective of cellulitis status, and 5 who were scheduled to be discharged by the emergency department. Interventions: Early dermatology consultation for presumed cellulitis. Main Outcomes and Measures: Primary outcomes were patient disposition and rates of antibiotic use. Results: Of 116 patients (63 [54.3%] women; 91 [78.4%] non-Hispanic white; mean [SD] age, 58.4 [19.1] years), 39 (33.6%) were diagnosed with pseudocellulitis by dermatologists. Of these, 34 (87.2%) had started using antibiotics for presumed cellulitis as prescribed by the primary team at the time of enrollment. The dermatology team recommended antibiotic discontinuation in 28 of 34 patients (82.4%), and antibiotics were stopped in 26 of 28 cases (92.9%). The dermatologists also recommended discharge from planned observation or inpatient admission in 20 of 39 patients with pseudocellulitis (51.3%), and the primary team acted on this recommendation in 17 of 20 cases (85.0%). No patients diagnosed with pseudocellulitis experienced worsening condition after discharge based on phone and clinic follow-up (30 of 39 [76.9%] follow-up rate). Extrapolating the impact of dermatology consultation for presumed cellulitis nationally, we estimate 97 000 to 256 000 avoided hospitalization days, 34 000 to 91 000 patients avoiding unnecessary antibiotic exposure, and $80 million to $210 million in net cost savings annually. Conclusions and Relevance: Early consultation by dermatologists for patients with presumed cellulitis represents a cost-effective intervention to improve health-related outcomes through the reduction of inappropriate antibiotic use and hospitalization. PMID- 29453876 TI - Prognostic importance of FGF2 and FGFR1 expression for patients affected by ameloblastoma. AB - BACKGROUND: Fibroblast growth factor 2 (FGF2) and FGF receptor 1 (FGFR1) have been investigated in different human neoplasms and were shown to play important roles in the pathogenesis of these diseases; however, very few are known regarding their prognostic importance in the context of ameloblastoma. Therefore, the aim of this study was to investigate whether the expression of FGF2 and FGFR1 is associated with ameloblastoma clinical behavior. METHODS: Fifty-eight cases of ameloblastoma arranged in tissue microarray were submitted to immunohistochemistry against FGF2 and FGFR1. Clinicopathological parameters regarding sex, age, tumor size, duration and location, treatment, recurrences, radiographic features, cortical disruptions, and follow-up data were obtained from patients' medical records and correlated with the molecules expression. Univariate and multivariate Cox regression analyses were used to investigate the prognostic potential of the biomarkers. RESULTS: Forty-four cases (75.9%) exhibited cytoplasmic positivity for FGF2 in central and peripheral epithelial cells, 46 of 58 (79.3%) showed FGFR1 cytoplasmic positivity predominantly in the columnar peripheral cells, and 43 cases (74.1%) were positive for both. Expression of FGF2 and FGF2 + FGFR1 was associated with tumor recurrences (P = .05). However, univariate and multivariate analyses did not demonstrate a significant influence of FGF2, FGFR1, or FGF2 + FGFR1 in the 5-year disease-free survival (DFS) rate (P = .27, P = .33, and P = .25, respectively). CONCLUSION: Cytoplasmic expression of FGF2 and FGF2 + FGFR1 is associated with ameloblastoma recurrence, but FGF2 and FGFR1 are not determinants of a lower DFS. PMID- 29453877 TI - Significance of mitochondria on cardiometabolic syndromes. AB - Metabolic syndromes (MS) are a cluster of disorders such as obesity, hypertension, dyslipidemia, and diabetes. Cardiometabolic syndrome (CMS), a branch of MS, is a group of diseases affecting cardiovascular, renal, metabolic, prothrombotic, and inflammatory abnormalities due to defects in energy metabolism. Since the emergence of molecular biology and the discovery of pathogenic mitochondrial DNA defect in the 1980s, research advances have revealed a number of common human diseases involving mitochondrial dysfunction. One of the major defects in CMS and its associated diseases is excess cellular oxidative stress and oxidative damage to mitochondrial components. In this study, we overview specific aspects of mitochondrial biology that have contributed and likely will continue enhance the progress of development of therapeutics for CMS. During the last decade, however, increasing evidence has emerged supporting the role of mitochondrial functional parameters in the genesis of various metabolism related disorders. The biochemical pathways which modulate various mitochondrial functional indicators such as mitochondrial biogenesis, mitochondrial membrane potential, electron transport chain and ATP synthesis, intramitochondrial oxidative stress, and mitochondria-mediated cell death have been recognized in diagnosis and prognosis of various disorders associated with energy metabolism and heart function. PMID- 29453878 TI - Estimated glomerular filtration rate in stable older kidney transplant recipients are present algorithms valid? A national cross-sectional cohort study. AB - Several equations have been developed for estimated glomerular filtration rate (eGFR) in patients with chronic kidney disease (CKD), but none were developed based on data from elderly kidney transplant recipients (KTR). The primary aim of this study was to evaluate different creatinine-based equations in stable elderly KTR. A national cross-sectional study was performed using data from 263 consecutive kidney transplant recipients 60 years or older who performed a routine GFR measurement one year after engraftment. GFR was measured by iohexol clearance calculation based on two samples. eGFR was calculated from a range of different creatinine-based equations using information obtained at the time of GFR measurement. Bias, precision, and accuracy were evaluated for each equation. All equations apart from Nankivell had accuracy (P30) > 80%. The BIS1, FAS, LMRCR , and Cockcroft & Gault equations in recipients older than 70 years and the FAS, LMRCR , and MDRD in recipients 60-69 years old had nonsignificant bias. The CKD EPI had significant bias in both groups. If one should choose a single equation for follow-up of individual CKD progression in all recipients >= 60 years, the FAS or LMRCR equations are probably the best alternatives. PMID- 29453880 TI - Information bias in epidemiological studies with a special focus on obstetrics and gynecology. AB - Information bias occurs when any information used in a study is either measured or recorded inaccurately. This paper describes some of the most common types of information bias, using examples from obstetrics and gynecology, and describes how information bias may affect results of observational studies. Non differential misclassification occurs when the degree of misclassification of exposure status among those with and those without the disease is the same; in cohort studies, this type of bias is most likely and will bias estimates toward no association when exposure is dichotomized. Non-differential underreporting of an exposure with more than two categories may mask a true threshold effect as a dose-response relation and, if a true threshold effect exists, the threshold will be set at too low a level, if the exposure is underreported. Differential misclassification may cause bias in either direction and is particularly likely, when exposure status is reported after the outcome occurred. Misclassification of confounders is an issue that needs special attention by researchers, as failure to measure accurately one or more (strong) confounders may seriously bias the observed results. Misclassification of disease status may also cause bias of estimates of association in either direction. Information bias is probably best prevented during planning of data collection, as there are few and insufficient methods available for correcting inaccurate information. PMID- 29453879 TI - Defining outcomes for beta-cell replacement therapy in the treatment of diabetes: a consensus report on the Igls criteria from the IPITA/EPITA opinion leaders workshop. AB - beta-cell replacement therapy, available currently as pancreas or islet transplantation, has developed without a clear definition of graft functional and clinical outcomes. The International Pancreas & Islet Transplant Association (IPITA) and European Pancreas & Islet Transplantation Association (EPITA) held a workshop to develop consensus for an IPITA/EPITA Statement on the definition of function and failure of current and future forms of beta-cell replacement therapy. There was consensus that beta-cell replacement therapy could be considered as a treatment for beta-cell failure, regardless of etiology and without requiring undetectable C-peptide, accompanied by glycemic instability with either problematic hypoglycemia or hyperglycemia. Glycemic control should be assessed at a minimum by glycated hemoglobin (HbA1c ) and the occurrence of severe hypoglycemia. Optimal beta-cell graft function is defined by near-normal glycemic control [HbA1c <= 6.5% (48 mmol/mol)] without severe hypoglycemia or requirement for insulin or other antihyperglycemic therapy, and with an increase over pretransplant measurement of C-peptide. Good beta-cell graft function requires HbA1c < 7.0% (53 mmol/mol) without severe hypoglycemia and with a significant (>50%) reduction in insulin requirements and restoration of clinically significant C-peptide production. Marginal beta-cell graft function is defined by failure to achieve HbA1c < 7.0% (53 mmol/mol), the occurrence of any severe hypoglycemia, or less than 50% reduction in insulin requirements when there is restoration of clinically significant C-peptide production documented by improvement in hypoglycemia awareness/severity, or glycemic variability/lability. A failed beta-cell graft is defined by the absence of any evidence for clinically significant C-peptide production. Optimal and good functional outcomes are considered successful clinical outcomes. PMID- 29453881 TI - Identification of cancer-related potential biomarkers based on lncRNA-pseudogene mRNA competitive networks. AB - Accumulating evidence indicates that mRNAs and noncoding RNAs act as competitive endogenous RNAs (ceRNAs) and play a key role in tumorigenesis. However, the complex competitive relationship among genes remains unknown. In the present study, the long noncoding RNAs (lncRNAs), pseudogenes and mRNAs that compete with common microRNAs are defined as lncRNA-pseudogene-mRNA competitive triples. We find that some candidate ceRNAs, modules and triples are associated with cancers and can significantly divide patients into high-risk and low-risk groups; thus, they may serve as potential cancer biomarkers. In sum, the present study systematically analyzes the association between competitive triples and cancer, which provides a reference for a deeper understanding of cancer progression. PMID- 29453882 TI - Early kidney allograft loss-Is there scope for improvement? PMID- 29453883 TI - Entangled signal pathways can both control expression stability and induce stochastic focusing. AB - Gene transcription is often controlled by multiple interacting signal pathways, but how these pathways impact gene expression is not fully understood. Here, we refine a mechanic model based on experiments in murine embryonic stem cells and analyze the influence of pathway-pathway cross-talk strength (CTS) on mRNA expression stability. We find that the CTS can tune this stability, depending on the manner of regulation. Furthermore, there is an optimal CTS such that the expression pattern is most stable but free energy consumption is at its highest; the CTS can induce stochastic focusing of the mRNA level but this is at the cost of energy. In both cases, there is a cross-talk-mediated trade-off, implying that entangled signal pathways can control both expression stability and energy dissipation. PMID- 29453884 TI - Daratumumab resistance is frequent in advanced-stage multiple myeloma patients irrespective of CD38 expression and is related to dismal prognosis. AB - OBJECTIVE: Daratumumab is a promising new antimyeloma agent. We report a single center "real-world" series of multiple myeloma (MM) and amyloidosis (AL) patients treated with daratumumab. METHODS: Forty-one patients were included: 7 second line MM, 30 heavily pretreated (median number of therapies of 5) advanced MM, and 4 with AL. RESULTS: Second-line patients and advanced AL showed high rate of durable overall responses. However, advanced MM patients had a dismal prognosis with an overall response rate (ORR) of 36%, and a short median progression-free and overall survival of 2.3 and 6.6 months, respectively. Responses were particularly poor in patients with extramedullary plasmacytomas. Neither the addition of another agent to daratumumab nor changing to the next line of therapy produced significant durable responses in this patient population. Flow cytometry analysis demonstrated that CD38 expression level was not predictive of response. We show that CD38 expression dynamics by a commercially available anti-CD38 antibody after daratumumab administration was hindered by competitive binding of daratumumab. CONCLUSIONS: Responses to daratumumab and combinations in patients with advanced MM, particularly with extramedullary disease, are low and short lived, stressing the administration of this agent should be early in the course of the disease. PMID- 29453885 TI - Bacterial neuraminidase-mediated erythrocyte desialylation provokes cell surface aminophospholipid exposure. AB - BACKGROUND: Surface desialylation is associated with erythrocyte aging and mediates phagocytic recognition and clearance of senescent erythrocytes. Neuraminidases, a family of glycohydrolytic enzymes, cleave the glycosidic linkages between sialic acid and mucopolysaccharides and have previously been implicated in erythrocyte dysfunction associated with sepsis. Erythrocytes in septic patients further display a phenotype of accelerated eryptosis characterized by membrane phospholipid scrambling resulting in phosphatidylserine (PS) externalization. Herein, we examined the impact of artificial erythrocyte desialylation on eryptosis. METHODS: Using flow cytometry and/or fluorescence microscopy, we analyzed desialylation patterns and eryptotic alterations in erythrocytes exposed to Clostridium perfringens-derived neuraminidase. RESULTS: Exogenous bacterial neuraminidase significantly augmented membrane PS exposure and cytosolic Ca2+ levels in a dose- and time-dependent manner. Neuraminidase treatment significantly reduced fluorescence-tagged agglutinin binding, an effect temporally preceding the increase in PS externalization. Neuraminidase-induced PS exposure was significantly curtailed by pretreatment with the pan-sialidase inhibitor N-acetyl-2,3-dehydro-2-deoxyneuraminic acid. Neuraminidase treatment further induced hemolysis but did not significantly impact erythrocyte volume, ceramide abundance, or the generation of reactive oxygen species. CONCLUSION: Collectively, our data reveal that alteration of erythrocyte sialylation status by bacterial neuraminidase favors eryptotic cell death, an effect potentially contributing to reduced erythrocyte lifespan and anemia in sepsis. PMID- 29453886 TI - Restructuring training in transplantation surgery ...and medicine: a necessity on both sides of the Atlantic. PMID- 29453887 TI - Coronary artery disease in heart transplantation: new concepts for an old disease. AB - Cardiac allograft vasculopathy (CAV) remains one of the main long-term complications after heart transplantation. We performed a systematic review focused on articles published in the previous 6 years to reappraise the novel evidences supporting risk factors, pathology, prevention, and treatment of CAV. We identified a search string for a literature search on PubMed. We excluded articles specifically focused on diagnosis/biomarkers/imaging only or complications of other diseases. We included 98 studies out of our search. Forty eight articles describe risk factors for CAV, 13 pathology, 24 prevention, and 13 treatment for CAV. While confirming known concepts, we found supportive evidence that CAV pathophysiology may vary according to the time post-transplant and the prevalence of metabolic versus immune-mediated risk factors. Selective revascularization of focal lesions in patients with CAV may result in some clinical benefit, but CAV prevention, rather than treatment, by controlling risk factors and by using targeted immunosuppressive therapies is the most evidence based approach to reduce disease progression. PMID- 29453888 TI - Dual transcriptomics reveals co-evolutionary mechanisms of intestinal parasite infections in blue mussels Mytilus edulis. AB - On theoretical grounds, antagonistic co-evolution between hosts and their parasites should be a widespread phenomenon but only received little empirical support so far. Consequently, the underlying molecular mechanisms and evolutionary steps remain elusive, especially in nonmodel systems. Here, we utilized the natural history of invasive parasites to document the molecular underpinnings of co-evolutionary trajectories. We applied a dual-species transcriptomics approach to experimental cross-infections of blue mussel Mytilus edulis hosts and their invasive parasitic copepods Mytilicola intestinalis from two invasion fronts in the Wadden Sea. We identified differentially regulated genes from an experimental infection contrast for hosts (infected vs. control) and a sympatry contrast (sympatric vs. allopatric combinations) for both hosts and parasites. The damage incurred by Mytilicola infection and the following immune response of the host were mainly reflected in cell division processes, wound healing, apoptosis and the production of reactive oxygen species (ROS). Furthermore, the functional coupling of host and parasite sympatry contrasts revealed the concerted regulation of chitin digestion by a Chitotriosidase 1 homolog in hosts with several cuticle proteins in the parasite. Together with the coupled regulation of ROS producers and antagonists, these genes represent candidates that mediate the different evolutionary trajectories within the parasite's invasion. The host-parasite combination-specific coupling of these effector mechanisms suggests that underlying recognition mechanisms create specificity and local adaptation. In this way, our study demonstrates the use of invasive species' natural history to elucidate molecular mechanisms of host parasite co-evolution in the wild. PMID- 29453889 TI - Mitochondrial dysfunction and axon degeneration in progressive multiple sclerosis. AB - The neuron is the target of inflammatory demyelinating processes in multiple sclerosis (MS). In progressive MS, however, there is a gathering body of evidence indicating that molecular changes converge on mitochondria within neuronal cell bodies. The most reproducible change relates to mitochondrial respiratory chain complex deficiency, which compromises the capacity of neurons to generate ATP. The resulting energy failure state is coupled with an increase in demand for energy by the demyelinated axon, being particularly relevant to the long tracts such as corticospinal tracts with long projection axons. Recent work in our laboratory and that of our collaborators indicates the limited reflection of the mitochondria changes within neurons in experimental disease models. The mitochondrial changes within neuronal compartments are likely to offer novel targets for the improvement in neuronal function in patients with progressive MS. PMID- 29453890 TI - The co-developmental dynamic of sport and school burnout among student-athletes: The role of achievement goals. AB - Student-athletes who strive for success in high-level sports while pursuing upper secondary education may be prone to sport and school burnout. This study examined the co-developmental dynamic of sport and school burnout in Finnish adolescent student-athletes (Ntime 1 = 391; Ntime 2 = 373) across the first year of upper secondary school using cross-lagged structural equation modeling (SEM). Furthermore, we used sport and school-related achievement goals as predictors of sport and school burnout, namely sport and school-related exhaustion, cynicism, and feelings of inadequacy. The results showed that burnout dimensions in a particular domain were substantially stable within the same domain during the first year of upper secondary school and that school-related exhaustion at the beginning of upper secondary school predicted sport-related exhaustion at the end of the school year. Mastery goals in sport and school were negatively associated with cynicism and feelings of inadequacy within the same domain. Furthermore, performance goals in school were positively associated with school-related cynicism. The results can be used by healthcare professionals for early prevention of student-athletes' burnout. PMID- 29453891 TI - An investigation of an open-access model for scaling up methadone maintenance treatment. AB - AIMS: To examine retrospectively patient and programmatic outcomes following the development and implementation of an 'open-access' model in which prospective patients were enrolled rapidly in methadone maintenance treatment, irrespective of ability to pay, and provided real-time access to multiple voluntary treatment options. DESIGN: Medical and administrative records were abstracted to compare data for 1 year before and 9 years after initiating the implementation of an open access treatment model in May 2007. SETTING: Methadone maintenance treatment center in Connecticut, USA. PARTICIPANTS: Individuals with opioid use disorder entering treatment between July 2006 and June 2015. In June 2015, 64% (n = 2594) of the sample were men and 80% (n = 3133) reported that they were white. INTERVENTION: The Network for the Improvement of Addiction Treatment-informed open-access treatment model uses process improvement strategies to improve treatment access and capacity. MEASUREMENTS: Census, waiting time, retention, non medical opioid use, patient mortality and financial sustainability (net income and state-block grants as proportions of revenue). FINDINGS: In the 9 years following the initial implementation of the open-access model, patient census increased by 183% from 1431 to 4051, and average waiting-time days decreased from 21 to 0.3 (same day) without apparent deleterious effects on rates of retention, non-medical opioid use or mortality. Between fiscal years (FY) 06 and FY 15, net operating margin rose from 2 to 10%, while state-block grant revenues declined 14% and the proportion of total revenue from state-block grant revenue decreased from 49 to 24%. CONCLUSIONS: An open-access model for rapid enrolment of people with opioid use disorder in methadone treatment appears to improve treatment access, capacity, and financial sustainability without evidence of deleterious effects on treatment outcomes. PMID- 29453892 TI - HIV-1 gp41 transmembrane oligomerization monitored by FRET and FCS. AB - The HIV-1 envelope gp120/gp41 trimer mediates viral membrane fusion. After cluster of differentiation-4 recognition, gp120 detaches from the virus, exposing gp41 which triggers fusion. During the fusion process, gp41 may not remain trimeric, which could have functional importance. Here, we probe the reversible association of full length gp41 (minus the cytoplasmic domain) in detergent micelles (with probes attached to transmembrane domain) by fluorescence resonance energy transfer (FRET) with a MUm dissociation constant. This is compared with other methods. A gp41-targeted fusion inhibitor must interfere with this transition, and monomeric, partially monomeric or trimeric states all present potential binding epitopes. The gp41 self-association is a valid drug target model and FRET, a potential high-throughput assay system, could be used to screen drug libraries. PMID- 29453893 TI - CBCT-guided evolutive library for cervical adaptive IMRT. AB - PURPOSE: In the context of adaptive radiation therapy (ART) for locally advanced cervical carcinoma (LACC), this study proposed an original cone-beam computed tomography (CBCT)-guided "Evolutive library" and evaluated it against four other known radiotherapy (RT) strategies. MATERIAL AND METHODS: For 20 patients who underwent intensity-modulated radiation therapy (IMRT) for LACC, three planning CTs [with empty (EB), intermediate (IB), and full (FB) bladder volumes], a CT scan at 20 Gy and bi-weekly CBCTs for 5 weeks were performed. Five RT strategies were simulated for each patient: "Standard RT" was based on one IB planning CT; "internal target volume (ITV)-based RT" was an ITV built from the three planning CTs; "RT with one mid-treatment replanning (MidTtReplan)" corresponded to the standard RT with a replanning at 20 Gy; "Pretreatment library ART" using a planning library based on the three planning CTs; and the "Evolutive library ART", which was the "Pretreatment library ART" strategy enriched by including some CBCT anatomies into the library when the daily clinical target volume (CTV) shape differed from the ones in the library. Two planning target volume (PTV) margins of 7 and 10 mm were evaluated. All the strategies were geometrically compared in terms of the percentage of coverage by the PTV, for the CTV and the organs at risk (OAR) delineated on the CBCT. Inadequate coverage of the CTV and OARs by the PTV was also assessed using deformable image registration. The cumulated dose distributions of each strategy were likewise estimated and compared for one patient. RESULTS: The "Evolutive library ART" strategy involved a number of added CBCTs: 0 for 55%; 1 for 30%; 2 for 5%; and 3 for 10% of patients. Compared with the other four, this strategy provided the highest CTV geometric coverage by the PTV, with a mean (min-max) coverage of 98.5% (96.4-100) for 10 mm margins and 96.2% (93.0-99.7) for 7 mm margins (P < 0.05). Moreover, this strategy significantly decreased the geometric coverage of the bowel. CTV undercoverage by PTV occurred in the anterior and superior uterine regions for all strategies. The dosimetric analysis at 7 mm similarly demonstrated that the "Evolutive library ART" increased the V42.75Gy of the CTV by 27%, 20%, 13%, and 28% compared with "Standard RT", "ITV-based RT", "MidTtReplan", and "Pretreatment library ART", respectively. The dose to the bowel was also decreased by the "Evolutive library ART" compared with that by the other strategies. CONCLUSION: The "Evolutive library ART" is a personalized ART strategy that comprises a pretreatment planning library of three CT scans, enriched for half of the patients by one to three per-treatment CBCTs. This original strategy increased both the CTV coverage and bowel sparing compared with all the other tested strategies and enables us to consider a PTV margin reduction. PMID- 29453894 TI - Organisation of lymphocytic infiltrates in ANCA-associated glomerulonephritis. AB - AIMS: Renal involvement in anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis contributes to significant morbidity and mortality in patients. In chronic inflammation, B cells are recruited to the inflamed tissue and organised lymphoid structures have been described in several autoimmune diseases. The aim of this study was to correlate the lymphoid organisation in renal biopsies with renal outcome in ANCA-associated glomerulonephritis (GN). METHODS AND RESULTS: We investigated 112 renal biopsies from patients with newly diagnosed ANCA associated necrotising GN. We identified four different levels of the intrarenal organisation of lymphocytes: T cells without B cells, scattered B and T cells, clustered lymphocytic infiltrates and nodular compartmentally arranged B and T cell aggregates. Almost half the patients showed clusters of B and T lymphocytes in their biopsies. In 15 of these biopsies, a higher degree of organisation with lymphocytic compartments was detected. Inflammatory cell organisation was associated with renal failure, but not with tubular atrophy and interstitial fibrosis. Patients with organised lymphocytic infiltrates in their biopsy had worse renal function during follow-up and were more likely to develop end stage renal disease. CONCLUSIONS: In the present study, we show that the renal lymphocytic organisation is associated with renal outcome in ANCA-associated GN. The organisation of the lymphocytic infiltrate may be a morphological correlate of a perpetual and exaggerated inflammation in renal ANCA disease. Classifying the lymphocytic infiltrate could help to predict renal outcome, and might therefore be used for individualised adjustments in the intensity and duration of immunosuppressive therapy. PMID- 29453895 TI - Cross-sectional studies - what are they good for? AB - Cross-sectional studies serve many purposes, and the cross-sectional design is the most relevant design when assessing the prevalence of disease, attitudes and knowledge among patients and health personnel, in validation studies comparing, for example, different measurement instruments, and in reliability studies. This paper describes the use of cross-sectional studies and provides examples within obstetrics and gynecology. Caveats are also described; for example, when cross sectional data is used for analytical purposes of associations between an exposure and an outcome, authors and readers should be careful not to make causal inferences, unless the exposure may safely be assumed to be stable over time and not influenced by experiencing the outcome. In such cases, analyses are also subject to selection and information bias as well as confounding. PMID- 29453896 TI - Antimalarial drug mefloquine inhibits nuclear factor kappa B signaling and induces apoptosis in colorectal cancer cells. AB - Nuclear factor kappa B (NF-kappaB) signaling pathway is activated in many colorectal cancer (CRC) cells and in the tumor microenvironment, which plays a critical role in cancer initiation, development, and response to therapies. In the present study, we found that the widely used antimalarial drug mefloquine was a NF-kappaB inhibitor that blocked the activation of IkappaBalpha kinase, leading to reduction of IkappaBalpha degradation, decrease of p65 phosphorylation, and suppressed expression of NF-kappaB target genes in CRC cells. We also found that mefloquine induced growth arrest and apoptosis of CRC cells harboring phosphorylated p65 in culture and in mice. Furthermore, expression of constitutive active IKKbeta kinase significantly attenuated the cytotoxic effect of the compound. These results showed that mefloquine could exert antitumor action through inhibiting the NF-kappaB signaling pathway, and indicated that the antimalarial drug might be repurposed for anti-CRC therapy in the clinic as a single agent or in combination with other anticancer drugs.

PMID- 29453901 TI - Shedding light on aberrant interactions - a review of modern tools for studying protein aggregates. AB - The link between protein aggregation and neurodegenerative disease is well established. However, given the heterogeneity of species formed during the aggregation process, it is difficult to delineate details of the molecular events involved in generating pathological aggregates from those producing soluble monomers. As aberrant aggregates are possible pharmacological targets for the treatment of neurodegenerative diseases, the need to observe and characterise soluble oligomers has pushed traditional biophysical techniques to their limits, leading to the development of a plethora of new tools capable of detecting soluble oligomers with high precision and specificity. In this review, we discuss a range of modern biophysical techniques that have been developed to study protein aggregation, and give an overview of how they have been used to understand, in detail, the aberrant aggregation of amyloidogenic proteins associated with the two most common neurodegenerative disorders, Alzheimer's disease and Parkinson's disease. PMID- 29453900 TI - Downregulation of reticulocalbin-1 differentially facilitates apoptosis and necroptosis in human prostate cancer cells. AB - Reticulocalbin 1 (RCN1), an endoplasmic reticulum (ER)-resident Ca2+ -binding protein, is dysregulated in cancers, but its pathophysiological roles are largely unclear. Here, we demonstrate that RCN1 is overexpressed in clinical prostate cancer (PCa) samples, associated with cyclin B, not cyclin D1 expression, compared to that of benign tissues in a Chinese Han population. Downregulation of endogenous RCN1 significantly suppresses PCa cell viability and arrests the cell cycles of DU145 and LNCaP cells at the S and G2/M phases, respectively. RCN1 depletion causes ER stress, which is evidenced by induction of GRP78, activation of PERK and phosphorylation of eIF2alpha in PCa cells. Remarkably, RCN1 loss triggers DU145 cell apoptosis in a caspase-dependent manner but mainly causes necroptosis in LNCaP cells. An animal-based analysis confirms that RCN1 depletion suppresses cell proliferation and promotes cell death. Further investigations reveal that RCN1 depletion leads to elevation of phosphatase and tensin homolog (PTEN) and inactivation of AKT in DU145 cells. Silencing of PTEN partially restores apoptotic cells upon RCN1 loss. In LNCaP cells, predominant activation of CaMKII is important for necroptosis in response to RCN1 depletion. Thus, RCN1 may promote cell survival and serve as a useful target for cancer therapy. PMID- 29453902 TI - Peri-operative outcomes and complications after laparoscopic vs robot-assisted dismembered pyeloplasty: a systematic review and meta-analysis. AB - OBJECTIVE: To analyse the current difference between dismembered robot-assisted pyeloplasty (RAP) and laparoscopic pyeloplasty (LP) in the treatment of pelvi ureteric junction (PUJ) obstruction as of 26 June 2017, focusing on operating time, length of hospital stay, complication rate, and success rate. PATIENTS AND METHODS: We searched PubMed, Medline and Embase databases, consulted experts, reviewed reference lists, used the 'related articles' PubMed feature, and reviewed scientific meeting abstracts for eligible articles published between 1993 and 26 June 2017. A modified Newcastle-Ottawa scale was used to assess study quality. Subgroup analyses were performed regarding patient age, single or multisurgeon experience, presence of complex renal anatomy, study quality, Clavien-Dindo grades, and length of follow-up. RESULTS: From 4101 identified articles, 17 studies meeting our eligibility criteria were included for data extraction. All were observational studies, with 10 deemed to be of low quality. Meta-analysis showed that RAP resulted in a 27-min shorter operating time (weighted mean difference [WMD] -26.71 min, 95% confidence interval [CI] -44.42 to -9.00; P = 0.003) and a 1.2-day shorter length of hospital stay (WMD -1.21 days, 95% CI -1.84 to -0.57; P = 0.003). The quality of evidence for these outcomes was rated as very low. Significant heterogeneity was found when analysing operating time (P < 0.001) and length of hospital stay (P < 0.001), which could not be fully explained through subgroup analyses. We also identified other potentially significant sources of bias for which we could not adjust our analysis. RAP was also associated with a lower complication rate (odds ratio [OR] 0.56, 95% CI 0.37 to 0.84; P = 0.005) and higher success rate (OR 2.76, 95% CI 1.30 to 5.88; P = 0.008); however, whether statistical advantages for these two outcomes translated into clinically significant advantages was unclear. The quality of evidence for these outcomes was rated as low. CONCLUSION: For patients with PUJ obstruction, our meta-analyses show that RAP is advantageous concerning operating time, length of hospital stay, complication rate and success rate. Our conclusions, however, are weakened by poor quality of evidence and significant study heterogeneity. In addition, whether the statistical significance observed in the present meta-analysis translates into clinical significance is an important question. Further high-quality studies, particularly randomized controlled trials, are necessary to strengthen conclusions. PMID- 29453903 TI - Tracking the Dynamic Folding and Unfolding of RNA G-Quadruplexes in Live Cells. AB - Because of the absence of methods for tracking RNA G-quadruplex dynamics, especially the folding and unfolding of this attractive structure in live cells, understanding of the biological roles of RNA G-quadruplexes is so far limited. Herein, we report a new red-emitting fluorescent probe, QUMA-1, for the selective, continuous, and real-time visualization of RNA G-quadruplexes in live cells. The applications of QUMA-1 in several previously intractable applications, including live-cell imaging of the dynamic folding, unfolding, and movement of RNA G-quadruplexes and the visualization of the unwinding of RNA G-quadruplexes by RNA helicase have been demonstrated. Notably, our real-time results revealed the complexity of the dynamics of RNA G-quadruplexes in live cells. We anticipate that the further application of QUMA-1 in combination with appropriate biological and imaging methods to explore the dynamics of RNA G-quadruplexes will uncover more information about the biological roles of RNA G-quadruplexes. PMID- 29453899 TI - The role of DNA-PK in aging and energy metabolism. AB - DNA-dependent protein kinase (DNA-PK) is a very large holoenzyme comprised of the p470 kDa DNA-PK catalytic subunit (DNA-PKcs ) and the Ku heterodimer consisting of the p86 (Ku 80) and p70 (Ku 70) subunits. It is best known for its nonhomologous end joining (NHEJ) activity, which repairs double-strand DNA (dsDNA) breaks (DSBs). As expected, the absence of DNA-PK activity results in sensitivity to ionizing radiation, which generates DSBs and defect in lymphocyte development, which requires NHEJ of the V(D)J region in the immunoglobulin and T cell receptor loci. DNA-PK also has been reported to have functions seemingly unrelated to NHEJ. For example, DNA-PK responds to insulin signaling to facilitate the conversion of carbohydrates to fatty acids in the liver. More recent evidence indicates that DNA-PK activity increases with age in skeletal muscle, promoting mitochondrial loss and weight gain. These discoveries suggest that our understanding of DNA-PK is far from complete. As many excellent reviews have already been written about the role of DNA-PK in NHEJ, here we will review the non-NHEJ role of DNA-PK with a focus on its role in aging and energy metabolism.

They were found to form robust organogels in several organic solvents. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), atomic force microscopy (AFM), FTIR spectroscopy, UV/Vis absorption spectroscopy, 1 H NMR spectroscopy, and X-ray diffraction (XRD) revealed that in these organogels, the molecules self-assembled into a nanofiber network with an H-type aggregation mode under the joint effect of pi-pi stacking, intermolecular hydrogen bonding, and van der Waals forces. Interestingly, the incorporation of the azobenzene mesogene into the rigid core led to photoisomerizable liquid crystal materials, which exhibited quick responsiveness to light and temperature, along with the trans-cis transition stimulated by UV light and heating. PMID- 29453905 TI - Sleep apnea and type 2 diabetes. AB - The aim of the present review was to clarify the association between obstructive sleep apnea (OSA) and type 2 diabetes, and discuss the therapeutic role of continuous positive airway pressure (CPAP) in type 2 diabetes. OSA patients are more likely than non-OSA populations to develop type 2 diabetes, while more than half of type 2 diabetes patients suffer from OSA. Similar to Western countries, in the East Asian population, the association between these two disorders has also been reported. CPAP is the primary treatment for OSA, but the effect of CPAP on comorbid diabetes has not been established. CPAP improved glucose metabolism determined by the oral glucose tolerance test in OSA patients, and several studies have shown that CPAP improves insulin resistance, particularly in obese populations undergoing long-term CPAP. Diabetes is associated with other sleep related manifestations as well, such as snoring and excessive daytime sleepiness. Snoring is associated with the development of diabetes, and excessive daytime sleepiness appears to modify insulin resistance. Well-designed studies are required to clarify the therapeutic effect of CPAP on diabetes. As both diabetes and OSA lead to cardiovascular disease, clinicians and healthcare professionals should be aware of the association between diabetes and OSA, and should take CPAP and health-related behaviors into consideration when treating patients with diabetes and/or OSA.

AB - INTRODUCTION: Hundreds of millions of people worldwide lack access to quality health services, largely because of geographic and socioeconomic maldistribution of qualified practitioners. This study describes differences between the practice locations of Philippines medical graduates from two 'socially accountable, community-engaged' health professional education (SAHPE) schools and the practice locations of graduates from two 'conventionally trained' medical schools located in the same respective geographic regions. Licensed medical graduates were currently practising in the Philippines and had been practising for at least 6 months. Graduates were from two Philippines SAHPE schools (Ateneo de Zamboanga University-School of Medicine (ADZU-SOM) on the Zamboanga Peninsula (n=212) and the University of the Philippines Manila-School of Health Sciences (SHS-Palo) in Eastern Visayas (n=71), and from two 'conventional' medical schools Methods: Current graduate practice locations in municipalities or cities were linked with their respective population size and socioeconomic income class, and geocoded using Geographical Information System software onto a geospatial map of the Philippines. Bivariate analysis compared the population size and socioeconomic class of communities where the SAHPE medical graduates practised to communities where 'conventional' medical school graduates practised. RESULTS: Thirty-one percent of ADZU-SOM medical graduates practised in communities <100 000 population versus 7% of graduates from the conventional school in the Zamboanga region (p<0.001), while 61% of SHS-Palo medical graduates practised in communities <100 000 population versus 12% of graduates from the conventional school in the Visayas region (p<0.001). Twenty-seven percent of ADZU-SOM graduates practised in lower income category communities (categories 2-6) versus 8% of graduates from the conventional school in the same region (p<0.001), while 49% of SHS-Palo graduates practised in lower income category communities (categories 2-6) versus 11% of graduates from the conventional school in the same region (p<0.001). CONCLUSIONS: SAHPE has contributed to increased medical coverage across rural and/or economically disadvantaged areas in two Philippines regions. The extensive community-based medical student placements associated with SAHPE likely play a significant role in graduates choosing to practice in rural and/or economically disadvantaged communities. Governments experiencing medical workforce maldistributions similar to those in the Philippines should consider SAHPE as a potentially cost-effective strategy in recruiting and retaining health graduates to underserved areas.

AB - Urinary tract infections (UTIs) caused by uropathogenic Escherichia coli (UPEC) are among the most common infectious diseases in humans. Due to their frequent occurrence in the community and nosocomial settings, as well as the development of resistance to the commonly prescribed antimicrobial agents, an enormous financial burden is placed on healthcare systems around the world. Therefore, novel approaches to the prevention and treatment of UTIs are needed. Although UPEC may harbour a plethora of virulence factors, type I fimbriae and P pili are two of the most studied adhesive organelles, since the attachment to host cells in the urinary tract is a crucial step towards infection. Design of receptor analogues that competitively bind to UPEC surface adhesins placed at the top of pili organelles led to the development of anti-adhesive drugs that are increasingly recognized as important and promising alternatives to antibiotic treatment of UTIs. PMID- 29453909 TI - A headspace-gas chromatography method for isopropanol determination in warfarin sodium products as a measure of drug crystallinity. AB - Coumadin(r) a nd s everal generic products of warfarin s odium (WS) contain the crystalline form (clathrate) in which WS and isopropanol (IPA) are associated in a 2:1 molar ratio. IPA is critical in maintaining the WS crystalline structure. Physicochemical properties of the drug and drug product may change when the crystalline drug transforms to amorphous form. A headspace-gas chromatography (HS GC) method was developed and validated for IPA determination in the WS drug product. n-propanol (NPA) was used as internal standard and the method was validated for specificity, system suitability, linearity, accuracy, precision, range, limits of detection and quantification, and robustness. The method was specific, with good resolution between IPA and NPA peaks. Chromatographic parameters (retention time, IPA/NPA area ratio, tailing factor, theoretical plates, USP symmetry, capacity factor, selectivity and resolution) were consistent over three days of validation. The analytical method was linear from 2 200 MUg mL-1 (0.1- 10 % IPA present in the drug product). LOD and LOQ were 0.1 and 2 MUg mL-1, respectively. Accuracy at low (2 MUg mL-1) and high (200 MUg mL 1) IPA concentrations of the calibration curve was 103.3-113.3 and 98.9-102.2 % of the nominal value, resp. The validated method was precise, as indicated by the RSD value of less than 2 % at three concentration levels of the calibration curve. The method reported here was utilized to determine accurately and precisely the IPA content in in-house formulations and commercial products. In summary, IPA determination by HS-GC provides an indirect measure of WS crystallinity in the drug product. Nevertheless, it should be confirmed by another analytical method since IPA from the drug substance is not distinguishable from IPA that may be present outside the drug crystals in a dosage form when prepared by wet granulation with IPA.

AB - The prediction power of partial least squares (PLS) and multivariate curve resolution-alternating least squares (MCR-ALS) methods have been studied for simultaneous quantitative analysis of the binary drug combination - doxylamine succinate and pyridoxine hydrochloride. Analysis of first-order UV overlapped spectra was performed using different PLS models - classical PLS1 and PLS2 as well as partial robust M-regression (PRM). These linear models were compared to MCR-ALS with equality and correlation constraints (MCR-ALS-CC). All techniques operated within the full spectral region and extracted maximum information for the drugs analysed. The developed chemometric methods were validated on external sample sets and were applied to the analyses of pharmaceutical formulations. The obtained statistical parameters were satisfactory for calibration and validation sets. All developed methods can be successfully applied for simultaneous spectrophotometric determination of doxylamine and pyridoxine both in laboratory prepared mixtures and commercial dosage forms. PMID- 29453911 TI - Induction of xenobiotic-metabolizing enzymes in hepatocytes by beta naphthoflavone: Time-dependent changes in activities, protein and mRNA levels. AB - In the present study, time-dependency of the induction effect of a selective inducer on the activity, protein and mRNA levels of cytochromes P450 1A1/2 (CYP1A1/2), NAD(P)H:quinone oxidoreductase 1 (NQO1) and glutathione S transferases (GSTA), in primary culture of rat hepatocytes was tested and evaluated. To show the differences in responses of tested enzymes, the common aryl hydrocarbon receptor (AhR) ligand agonist, beta-naphthoflavone (BNF), was used. Induction of CYP1A1/2 by BNF was detected at all time intervals and at all levels (i.e., mRNA, protein, enzyme activity). Different responses of NQO1 and GSTA upon BNF treatment were observed. Our results demonstrate that the responses of different xenobiotic-metabolizing enzymes to the inducer vary in time and depend on the measured parameter. For these reasons, an induction study featuring only one-time interval treatment and/ or one parameter testing could produce misleading information. PMID- 29453912 TI - HPTLC determination of diosgenin in fenugreek seeds. AB - A new HPTLC-densitometric method for diosgenin determination in fenugreek seeds was established after optimization of the conditions for efficient saponin extraction and acid hydrolysis. Several procedures were tested, the best of which was a three-step Soxhlet extraction, followed by hydrolysis of the obtained methanolic extract with 2 mol L-1 H2SO4. Best diosgenin separation from other hydrolysis products was obtained on HPTLC Si60F254 plates u sing a mixture of n heptane/ethyl acetate (7:3, V/V) and modified anisaldehyde as a spraying reagent. The method was preliminarily validated and the determined amounts of diosgenin in fenugreek seeds of Polish and African origin were found to be similar and ranged from 0.12-0.18 %. PMID- 29453913 TI - Chronic fluoxetine treatment induces lipid accumulation but does not alter the expression of Pref-1 in rat adipose tissue. AB - This study aims to investigate the effects of chronic fluoxetine (FLX) treatment on preadipocyte factor-1 (Pref-1) expression in subcutaneous, visceral and brown adipose tissues, and on the size of vacuoles in a dipocytes obtained from the perirenal regions in rats. Twenty-eight Wistar rats were treated with FLX at two different doses and fourteen animals received vehicle. After 40 days of treatment, the subcutaneous, perirenal and interscapular adipose tissues were collected. Pref-1 expression was examined using an immunohistochemical method and the vacuolar area was measured in stained sections. In the low dose FLX group, the size of vacuoles increased both in male and female animals. The high dose of FLX also induced a significant increase of vacuole size, but only in male animals. Neither of the two doses of FLX has significantly affected the Pref-1 expression in any type of adipose tissue. PMID- 29453914 TI - Medication adherence and health-related quality of life among patients with chronic obstructive pulmonary disease. AB - This study evaluated medication adherence and health-related quality of life (HRQoL) of Slovenian patients with chronic obstructive pulmonary disease (COPD) and examined the factors associated with HRQoL. Demographic and therapy information was collected from 65 patients through interviews. The St. George's Respiratory Questionnaire and the Morisky Medication Adherence Scale were used to evaluate HRQoL and adherence, resp. A multiple linear regression model was used to assess the association between the factors and HRQoL. The mean St. George's Respiratory Questionnaire score (range 0-100, with higher scores indicating lower HRQoL) was 41.4. COPD affected patients' daily activities more than their social and psychological functioning. Slightly more than 53 % of the patients were optimally adherent, while 12 % were non-adherent. Patients with lower HRQoL had a larger number of medications for concomitant diseases, experienced COPD exacerbation in the last year, and had less education. No statistically significant correlation was found between medication adherence and HRQoL. PMID- 29453915 TI - Efficacy of nucleoside analogues for hepatitis B virus-related liver failure: A network meta-analysis. AB - The purpose of this study was to compare the efficacy of nucleoside analogues (NAs) in the treatment of HBV-related liver failure. The data of patients with HBV-related liver failure treated with nucleoside analogues were used to conduct a network meta-analysis. A total of 1660 patients from 12 articles about the efficacy of lamivudine, entecavir, telbivudine and tenofovir for HBV-related liver failure treatment were recruited in the study. The highest two- and three month survival rate was recorded for patients using tenofovir. The end-stage liver disease (MELD) score and mortality in patients undergoing tenofovir treatment were the lowest. Patients treated with telbivudine had the highest one month survival rate. Patients receiving enticavir therapy showed the lowest HBV DNA level. Our results indicate that tenofovir may be the best therapy for the treatment of HBV-related liver failure compared to other nucleoside analogues (including lamivudine, entecavir and telbivudine) and non-NAs treatment. PMID- 29453916 TI - Distinguishing Smilax glabra and Smilax china rhizomes by flow-injection mass spectrometry combined with principal component analysis. AB - Flow-injection mass spectrometry (FIMS) coupled with a chemometric method is proposed in this study to profile and distinguish between rhizomes of Smilax glabra (S. glabra) and Smilax china (S. china). The proposed method employed an electrospray-time-of-flight MS. The MS fingerprints were analyzed using principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA) with the aid of SIMCA software. Findings showed that the two kinds of samples perfectly fell into their own classes. Further predictive study showed desirable predictability and the tested samples were successfully and reliably identified. The study demonstrated that the proposed method could serve as a powerful tool for distinguishing between S. glabra and S. china. PMID- 29453917 TI - Comparative chemical investigation and evaluation of antioxidant and tyrosinase inhibitory effects of Withania somnifera (L.) Dunal and Solanum nigrum (L.) berries. AB - In the present study, berries of two different species of Solanaceae family, Withania somnifera (WS) and Solanum nigrum (SN), were extracted in methanol and then fractionated with solvents, ranging from non-polar to polar, for their phytochemical profiling and investigation of antioxidant and tyrosinase enzyme inhibition capacity. The methanolic extract and n-hexane, ethyl acetate (WSEA, SNEA) and aqueous fractions were chemically analyzed and evaluated for biological activity. Total flavonoids and total phenolics were quantified in WSEA (96.91 +/- 1.56 MUg QE mg-1 sample and 178.45 +/- 2.78 MUg GAE mg-1 s ample, r esp.) and S NEA (89.58 +/- 0.98 MUg QE mg-1 sample and 120.15 +/- 2.33 MUg GAE mg-1 sample, resp.). HPLC-DAD analysis of ethyl acetate fractions of WS and SN measured 13.74 and 5.34 MUg GAE mg-1 dry fraction and 3.72 and 3.41 MUg QE mg-1 dry fraction, resp. WSEA and SNEA fractions showed the highest 2,2-diphenyl-2-picryl hydrazyl (DPPH) radical scavenging, total antioxidant capacity and iron reducing power activity. The highest inhibition of tyrosinase enzyme was also exhibited by WSEA and SNEA (59.6 and 58.7 %) resp. This investigation justifies the medicinal value of W. somnifera and S. nigrum berry extracts as potential and readily available sources of natural antioxidants. Marked tyrosinase enzyme inhibition activity and antioxidant activity of both plant extracts might be due to polyphenols and flavonoids. PMID- 29453918 TI - High dose of histone deacetylase inhibitors affects insulin secretory mechanism of pancreatic beta cell line. AB - OBJECTIVE: Histone deacytylase inhibitors (HDACis) inhibit the deacetylation of the lysine residue of proteins, including histones, and regulate the transcription of a variety of genes. Recently, HDACis have been used clinically as anti-cancer drugs and possible anti-diabetic drugs. Even though HDACis have been proven to protect the cytokine-induced damage of pancreatic beta cells, evidence also shows that high doses of HDACis are cytotoxic. In the present study, we, therefore, investigated the eff ect of HDACis on insulin secretion in a pancreatic beta cell line. METHODS: Pancreatic beta cells MIN6 were treated with selected HDACis (trichostatin A, TSA; valproic acid, VPA; and sodium butyrate, NaB) in medium supplemented with 25 mM glucose and 13% heat-inactivated fetal bovine serum (FBS) for indicated time intervals. Protein expression of Pdx1 and Mafa in MIN6 cells was demonstrated by immunohistochemistry and immunocytochemistry, expression of Pdx1 and Mafa genes was measured by quantitative RT-PCR method. Insulin release from MIN6 cells and insulin cell content were estimated by ELISA kit. Superoxide production in MIN6 cells was measured using a Total ROS/Superoxide Detection System. RESULTS: TSA, VPA, and NaB inhibited the expression of Pdx1 and Mafa genes and their products. TSA treatment led to beta cell malfunction, characterized by enhanced insulin secretion at 3 and 9 mM glucose, but impaired insulin secretion at 15 and 25 mM glucose. Th us, TSA induced dysregulation of the insulin secretion mechanism. TSA also enhanced reactive oxygen species production in pancreatic beta cells. CONCLUSIONS: Our results showed that HDACis caused failure to suppress insulin secretion at low glucose concentrations and enhance insulin secretion at high glucose concentrations. In other words, when these HDACis are used clinically, high doses of HDACis may cause hypoglycemia in the fasting state and hyperglycemia in the fed state. When using HDACis, physicians should, therefore, be aware of the capacity of these drugs to modulate the insulin secretory capacity of pancreatic beta cells. PMID- 29453919 TI - Genetic and epigenetic differences of benign and malignant pheochromocytomas and paragangliomas (PPGLs). AB - Pheochromocytomas and paragangliomas (PPGLs) are tumors arising from the adrenal medulla and sympathetic/parasympathetic paraganglia, respectively. According to Th e Cancer Genome Atlas (TCGA), approximately 40% of PPGLs are due to germ line mutations in one of 16 susceptibility genes, and a further 30% are due to somatic alterations in at least seven main genes (VHL, EPAS1, CSDE1, MAX, HRAS, NF1, RET, and possibly KIF1B). Th e diagnosis of malignant PPGL was straight forward in most cases as it was defined as presence of PPGL in non-chromaffin tissues. Accordingly, there is an extreme need for new diagnostic marker(s) to identify tumors with malignant prospective. Th e aim of this study was to review all suggested genetic and epigenetic alterations that are remarkably different between benign and malignant PPGLs. It seems that more than two genetic mutation clusters in PPGLs and other genetic and methylation biomarkers could be targeted for malignancy discrimination in different studies. PMID- 29453920 TI - Effect of trans-chalcone on hepatic IL-8 through the regulation of miR-451 in male rats. AB - OBJECTIVE: Trans-chalcone is a chalcone with hepatoprotective and anti inflammatory effects. However, the mechanism of these positive effects, especially on miR-451 as an inflammatory regulator, is poorly understood. In this regard, this microRNA (miRNA) acts by inhibition of hepatic interleukin-8 (IL-8) production in the liver which is one of the main proinflammatory cytokines. Th is study for the first time examined the effect of trans-chalcone on miR-451/IL-8 pathway. METHODS: In present study, 21 male rats were randomly divided into 3 groups (n=7 per each group): control which received solvent (NS), groups 2 (N2T) and 3 (N6T), which received transchalcone for 2 and 6 weeks, respectively. Hepatic level of miR-451 was measured by qRT-PCR. Serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) as well as hepatic level of IL-8 protein were measured. RESULTS: Trans-chalcone decreased hepatic level of IL-8 protein and serum level of ALT aft er 2 weeks of treatment without significant change in hepatic miR-451. Moreover, it increased hepatic level of miR-451 and reduced hepatic IL-8 as well as AST and ALT aft er 6 weeks. CONCLUSION: Based on the results of present study, miR-451/IL-8 pathway is a possible mechanism for hepatoprotective action of trans-chalcone in long-term. PMID- 29453921 TI - Changes in erythrocyte deformability during day and possible role of melatonin. AB - OBJECTIVES: The deformability of erythrocytes is their ability to change shape in order to pass through the capillaries. Th is is necessary for quality of microcirculation and sufficient delivery of oxygen to the tissues. Th e aim of our study was to investigate the possible spontaneous changes in the erythrocyte deformability during day and evaluation of the possible direct effects of melatonin (hormone involved in regulation of biorhythms) on the erythrocyte deformability. METHODS: Samples of capillary blood were taken from 12 healthy volunteers in the morning (8:00) and early in the evening (16:30). Determination of erythrocyte deformability was done based on the measurement of their filtrability. It was measured immediately aft er the sample collection and 2-hour lasting incubation without or with melatonin (2000 MUmol/L). RESULTS: Erythrocyte deformability was significantly lower in the morning (filtrability index: 0.68+/ 0.01 morning vs. 0.71+/-0.01 early evening, p<0.05). Th e incubation of blood samples with melatonin did not have impact on deformability. CONCLUSIONS: We suggest the presence of diurnal changes in erythrocyte deformability with worse values in the morning that may contribute to higher risk of ischemic attacks in the morning hours. Direct in vitro effect of melatonin on deformability was not observed, but possible in vivo effects cannot be excluded. PMID- 29453922 TI - A short review of primary aldosteronism in a question and answer fashion. AB - OBJECTIVES: The aim of this study was to present up to date information concerning the diagnosis and treatment of primary aldosteronism (PA). PA is the most common cause of endocrine hypertension. It has been reported up to 24% of selective referred hypertensive patients. METHODS: We did a search in Pub-Med and Google Scholar using the terms: PA, hyperaldosteronism, idiopathic adrenal hyperplasia, diagnosis of PA, mineralocorticoid receptor antagonists, adrenalectomy, and surgery. We also did cross-referencing search with the above terms. We had divided our study into five sections: Introduction, Diagnosis, Genetics, Treatment, and Conclusions. We present our results in a question and answer fashion in order to make reading more interesting. RESULTS: PA should be searched in all high-risk populations. The gold standard for diagnosis PA is the plasma aldosterone/plasma renin ratio (ARR). If this test is positive, then we proceed with one of the four confirmatory tests. If positive, then we proceed with a localizing technique like adrenal vein sampling (AVS) and CT scan. If the lesion is unilateral, after proper preoperative preparation, we proceed, in adrenalectomy. If the lesion is bilateral or the patient refuses or is not fit for surgery, we treat them with mineralocorticoid receptor antagonists, usually spironolactone. CONCLUSIONS: Primary aldosteronism is the most common and a treatable case of secondary hypertension. Only patients with unilateral adrenal diseases are eligible for surgery, while patients with bilateral and non surgically correctable PA are usually treated by mineralocorticoid receptor antagonist (MRA). Thus, the distinction between unilateral and bilateral aldosterone hypersecretion is crucial. PMID- 29453923 TI - Magnesium upregulates insulin receptor and glucose transporter-4 in streptozotocin-nicotinamide-induced type-2 diabetic rats. AB - OBJECTIVE: We investigated the effects of magnesium supplementation on glucose tolerance, insulin sensitivity, oxidative stress as well as the concentration of insulin receptor and glucose transporter-4 in streptozotocin-nicotinamide induced type-2 diabetic (T2D) rats. METHODS: Rats were divided into four groups designated as: 1) control (CTR); 2) diabetic untreated (DU); 3) diabetic treated with 1 mg of Mg/kg diet (Mg1-D); and 4) diabetic treated with 2 mg of Mg/kg diet (Mg2-D). T2D was induced with a single intraperitoneal (i.p.) injection of freshly prepared streptozotocin (55 mg/kg) aft er an initial i.p. injection of nicotinamide (120 mg/kg). Glucose tolerance, insulin sensitivity, lipid profile, malondialdehyde (MAD) and glutathione content, insulin receptors (INSR) and glucose transporter-4 (GLUT4), fasting insulin and glucose levels were measured, and insulin resistance index was calculated using the homeostatic model assessment of insulin resistance (HOMA-IR). RESULTS: Magnesium supplementation improved glucose tolerance and lowered blood glucose levels almost to the normal range. We also recorded a noticeable increase in insulin sensitivity in Mg-D groups when compared with DU rats. Lipid perturbations associated T2D were significantly attenuated by magnesium supplementation. Fasting glucose level was comparable to control values in the Mg-D groups while the HOMA-IR index was significantly lower compared with the DU rats. Magnesium reduced MDA but increased glutathione concentrations compared with DU group. Moreover, INSR and GLUT4 levels were elevated following magnesium supplementation in T2D rats. CONCLUSION: These findings demonstrate that magnesium may mediate effective metabolic control by stimulating the antioxidant defense, and increased levels of INSR and GLUT4 in diabetic rats. PMID- 29453924 TI - The World Health Organization (WHO) versus The International Association of Diabetes and Pregnancy Study Group (IADPSG) diagnostic criteria of gestational diabetes mellitus (GDM) and their associated maternal and neonatal outcomes. AB - Background Gestational diabetes mellitus (GDM) is a common medical complication in pregnancy. The aim of this study was to compare the prevalence of GDM using the World Health Organization (WHO) criteria and the International Association of Diabetes and Pregnancy Study Group (IADPSG) criteria in our population. We further compared the incidence of adverse maternal and neonatal outcomes in women diagnosed with GDM using these criteria and determined whether the IADPSG criteria is suitable in our population. Methods This randomized controlled trial was conducted at our antenatal clinic involving 520 patients from 1st February 2015 until 30th September 2017. They were randomized into the WHO and the IADPSG groups. All eligible women underwent a standard oral glucose tolerance test with 75 g glucose, their fasting and 2 h post prandial glucose levels were taken. The primary outcome was the prevalence of GDM. The secondary outcomes were the incidence of primary cesarean section, gestational hypertension or preeclampsia, preterm delivery <37 weeks, fetal macrosomia, neonatal hypoglycemia and shoulder dystocia or birth injury. Results The prevalence of GDM in both groups were similar (37.9% vs. 38.6%). GDM women in the WHO group had a significantly higher incidence of gestational hypertension or preeclampsia (p = 0.004) and neonatal hypoglycemia (p = 0.042). In contrast, GDM women in the IADPSG group had a significantly higher incidence of fetal macrosomia (p = 0.027) and cesarean section (p = 0.012). Conclusion The IADPSG diagnostic criteria for GDM may not be suitable for use in our population as it resulted in women being diagnosed later and being undertreated, thus leading to adverse maternal and neonatal outcomes. PMID- 29453925 TI - Impact of opioid therapy on gonadal hormones: focus on buprenorphine. AB - Objective The USA is in the midst of an opioid crisis. Understanding the impact of opioids and commonly used treatments for opioid dependence is essential for clinicians and researchers in order to educate and treat the nation's growing population with opioid use disorders. As a relatively new treatment for opioid dependence, buprenorphine is gaining popularity to the extent of becoming not only a preferred approach to the maintenance of opiate addiction, but also an option for chronic pain management. The purpose of this report is to review the available evidence on the endocrine effects of buprenorphine, particularly as it relates to the hypothalamic-pituitary-gonadal (HPG) axis, which is controversial and not fully defined. Method We conducted a Pubmed search (2000-2017) for human studies in the English language for articles that were available as full length regarding buprenorphine, endocrinopathy, hypogonadism, bone density, opioids. Case reports were also reviewed, although prospective studies and randomized controlled trials received more weight. Results Opioid induced hypogonadism is well established. Most studies report that buprenorphine being a partial agonist/antagonist may not be impacting the pituitary trophic hormones as much. There are reports of sexual dysfunction in subjects maintained on buprenorphine, some without hormonal correlation. Thus with the understanding that pertinent clinical studies are limited in number, varied in methodology, mostly cross sectional, predominantly in men and small number of participants, more research in this area is warranted. Conclusion Based on a comprehensive review of the available literature, we conclude that despite its increasing popularity, buprenorphine has not been adequately studied in respect to its long-term effects on the hypothalamic-pituitary-adrenal (HPA) axis. There is a great need for longitudinal systematic trials to define the potential buprenorphine-induced endocrine consequences. PMID- 29453926 TI - Sleep disorder prevalence in at-risk adolescents and potential effects of nightmare triad syndrome. AB - Objective At-risk high school students, those considered to have a higher probability for academic failure or dropping out, were assessed for various sleep disorders. Effects were compared between students with and without the nightmare triad syndrome (NTS+), the sleep disorders' cluster of frequent nightmares, insomnia disorder and suspected sleep-disordered breathing (SDB). Methods Data were gathered at a charter school for at-risk youth using: computer based surveys, physical airway exams, and mental health interviews by school social worker. Ninety-two students were enrolled, and 70 completed all study components. Results Students were teenaged [17.10 (1.50) years], male (52.2%) slightly overweight [BMI 25.50 (6.41)] Hispanics (87.0%); two-thirds (65 of 92) subjectively reported a sleep problem. Frequent nightmares (39.1%), insomnia (ISI >= 12, 41.3%), and SDB risk (79.3%) were common. Several presumptive sleep disorders (insomnia, SDB risk, parasomnia, or nightmares) were associated with worse sleep quality and lower quality of life. Nineteen students met criteria for NTS. Compared to NTS-, NTS+ showed significantly lower quality of life (p < 0.003, g = 0.84). Regression analyses revealed higher levels of depression and anxiety symptoms in NTS+ students. NTS was associated with reduced quality of life independent of anxiety symptoms. Conclusion Prevalence of presumptive sleep disorders was high with a tendency for clusters of sleep disorders in the same individual. Students with NTS+ showed worse outcomes and reduced quality of life, mediated partially by depression and anxiety. To examine relationships between sleep disorders and mental health in at-risk adolescents, research investigations must include both subjective and objective measurements of sleep.

PMID- 29453928 TI - CD4+CD25+CD127low FoxP3+ regulatory T cells in Crohn's disease. AB - BACKGROUND: Regulatory T (Treg) cell plays a key role in autoimmune diseases. We evaluated the regulatory function and frequency of Treg cells and secreted IL-10, IL-35 concentration in Crohn's disease (CD). METHODS: Twenty-three patients with CD and 25 healthy controls (HC) were included in this study. We analysed the alteration of Tregs frequency using flow cytometry for CD4, CD25, CD127 and FoxP3 markers. Surface expression of CD4, CD25 and CD127 markers were used for isolation of relatively pure Treg cells. Suppressive activity of Tregs was determined by measuring their ability to inhibit the proliferation of T responder (Tres) cells. In addition, the amounts of IL-10 and IL-35 cytokines in co-culture supernatants were measured by ELISA assay after stimulation with anti CD2/CD3/CD28. RESULTS: CD patients had significantly lower frequency of CD4+ CD25+ CD127low FoxP3+ Treg cells in comparison with controls (2.17 +/- 1.04 vs. 2.83 +/- 1.07, p = 0.0352). Additionally, Treg cells mediated suppression was not significantly different in CD patients compared to controls. There was a significant difference in IL-10 secretion in response to anti-CD2/CD3/CD28 stimulation compared with HC (p = 0.0074). CONCLUSION: The frequency of CD4+ CD25+ CD127low FoxP3+ Tregs decreased in active stage of CD but there was no impaired suppressive function of CD4+ CD25+ CD127low FoxP3+ Treg cells. We suggest that an alteration in the balance of Tregs and T effectors may contribute to pathogenesis of CD. PMID- 29453929 TI - The diagnostic and prognostic value of serum endocan in patients with cirrhotic cardiomyopathy. AB - BACKGROUND: We aimed to determine the relationship between endocan and cirrhotic cardiomyopathy. MATERIALS AND METHODS: Patients with liver cirrhosis and no heart disease were included in a prospective observational study with liver disease decompensation and death as primary outcomes. RESULTS: 83 cirrhotic patients were included and 32 had cirrhotic cardiomyopathy. Endocan levels were significantly lower in patients with cirrhotic cardiomyopathy (5.6 vs. 7 ng/mL, p = 0.034). Endocan correlated with severity of cirrhosis, time to decompensation or death from liver disease (OR 4.5 95% CI 1.06-31.1). CONCLUSION: Endocan is a promising biomarker of severity of cirrhosis and may help in the diagnosis of cardiac dysfunction in this population.

AB - Unraveling interactions among variables such as genetic, clinical, demographic and environmental factors is essential to understand the development of common and complex diseases. To increase the power to detect such variables interactions associated with clinical time-to-events outcomes, we borrowed established concepts from random survival forest (RSF) models. We introduce a novel RSF-based pairwise interaction estimator and derive a randomization method with bootstrap confidence intervals for inferring interaction significance. Using various linear and nonlinear time-to-events survival models in simulation studies, we first show the efficiency of our approach: true pairwise interaction-effects between variables are uncovered, while they may not be accompanied with their corresponding main-effects, and may not be detected by standard semi-parametric regression modeling and test statistics used in survival analysis. Moreover, using a RSF-based cross-validation scheme for generating prediction estimators, we show that informative predictors may be inferred. We applied our approach to an HIV cohort study recording key host gene polymorphisms and their association with HIV change of tropism or AIDS progression. Altogether, this shows how linear or nonlinear pairwise statistical interactions of variables may be efficiently detected with a predictive value in observational studies with time-to-event outcomes.

AB - BACKGROUND The aim of this study was to evaluate the reconstruction of a torn anterior cruciate ligament (ACL) with 10 mm diameter BPTB (bone-patellar tendon bone) autograft versus 8 mm HT (hamstring tendon) autografts, to compare the ability to restore pre-injury sports activities and reduce revision risk after these procedures. MATERIAL AND METHODS A prospective clinical review was performed to compare results of patients who underwent primary anatomical ACLR with 10 mm BPTB autografts with patients who underwent 8 mm diameter HT autografts, between January 2011 and January 2014. RESULTS There were 183 patients evaluated: the 8 mm HT group showed statistically significant higher knee laxity values compared to the 10 mm BPTB group (p=0.042), and significant difference were detected in subjective International Knee Documentation Committee (IKDC) evaluation scores; the average subjective IKDC evaluations after two-year follow-up in the HT group was 88.45+/-2.8 versus 89.24+/-2.5 in BPTB group (p=0.047). In the evaluation of the IKDC objective protocol, results were excellent and good in 83 patients (94.3%) after BPTB and in 78 patients (82%) after HT ACLR (p<0.05). The average score on the Tegner activity scale in the HT group decreased from 6.5 at pre-injury to 5.8 at two-year follow-up (p<0.001) and from 6.7 at pre-injury to 6.5 at two-year follow-up in the BPTB group (p=0.4). The ability to restore pre-injury sports activities was higher in the BPTB group (6.5) versus the HT group (5.8) (p<0.001). Revision was required for two patients (2.2%) in the BPTB group compared with 14 patients (14.7%) in the HT group (p<0.05). CONCLUSIONS Smaller HT graft size was a predictor of higher knee laxity and greater revision risk at two-year post primary ACL reconstruction. Larger diameter BPTB ACL grafts had a better ability to restore knee stability and greater ability to restore pre-injury sports activities. PMID- 29453932 TI - Neurotrophin-3 restores synaptic plasticity in the striatum of a mouse model of Huntington's disease. AB - AIMS: Neurotrophin-3 (NT-3) is expressed in the mouse striatum; however, it is not clear the NT-3 role in striatal physiology. The expression levels of mRNAs and immune localization of the NT-3 protein and its receptor TrkC are altered in the striatum following damage induced by an in vivo treatment with 3 nitropropionic acid (3-NP), a mitochondrial toxin used to mimic the histopathological hallmarks of Huntington's disease (HD). The aim of this study was to evaluate the role of NT-3 on corticostriatal synaptic transmission and its plasticity in both the control and damaged striatum. METHODS: Corticostriatal population spikes were electrophysiologically recorded and striatal synaptic plasticity was induced by high-frequency stimulation. Further, the phosphorylation status of Trk receptors was tested under conditions that imitated electrophysiological experiments. RESULTS: NT-3 modulates both synaptic transmission and plasticity in the striatum; nonetheless, synaptic plasticity was modified by the 3-NP treatment, where instead of producing striatal long-term depression (LTD), long-term potentiation (LTP) was obtained. Moreover, the administration of NT-3 in the recording bath restored the plasticity observed under control conditions (LTD) in this model of striatal degeneration. CONCLUSION: NT-3 modulates corticostriatal transmission through TrkB stimulation and restores striatal LTD by signaling through its TrkC receptor. PMID- 29453933 TI - Myt1l induced direct reprogramming of pericytes into cholinergic neurons. AB - OBJECTIVE: The cholinergic deficit is thought to underlie progressed cognitive decline in Alzheimer Disease. The lineage reprogramming of somatic cells into cholinergic neurons may provide strategies toward cell-based therapy of neurodegenerative diseases. METHODS AND RESULTS: Here, we found that a combination of neuronal transcription factors, including Ascl1, Myt1l, Brn2, Tlx3, and miR124 (5Fs) were capable of directly converting human brain vascular pericytes (HBVPs) into cholinergic neuronal cells. Intriguingly, the inducible effect screening of reprogramming factors showed that a single reprogramming factor, Myt1l, induced cells to exhibit similarly positive staining for Tuj1, MAP2, ChAT, and VAChT upon lentivirus infection with the 5Fs after 30 days. HBVP converted neurons were rarely labeled even after long-term incubation with BrdU staining, suggesting that induced neurons were directly converted from HBVPs rather than passing through a proliferative state. In addition, the overexpression of Myt1l induced the elevation of Ascl1, Brn2, and Ngn2 levels that contributed to reprogramming. CONCLUSIONS: Our findings provided proof of the principle that cholinergic neurons could be produced from HBVPs by reprogramming factor-mediated fate instruction. Myt1l was a critical mediator of induced neuron cell reprogramming. HBVPs represent another excellent alternative cell resource for cell-based therapy to treat neurodegenerative disease. PMID- 29453936 TI - A new method for the rapid characterization of root growth and distribution using digital image correlation. AB - Rapidly determining root growth patterns is biologically important and technically challenging. Current methods focus on direct observation of roots and require destructive excavations or time-consuming root tracing. We developed a novel methodology based on analyzing soil particle displacement, rather than direct observation of roots. This inferred root growth method uses digital image correlation (DIC) analysis, an established and high-throughput method used in many engineering and science disciplines. By applying DIC analyses to repeated images of plants grown in clear window boxes, we produced visually intuitive and quantifiable strain maps, indicating the magnitude and direction of soil movement. From this, we could infer root growth and rapidly quantify root system metrics. Strain measures were closely associated with the spatial distribution of roots and correlated with root length measured using conventional approaches. The method also allowed for the detection of root proliferation in nutrient-enriched soil patches, indicating its suitability for quantifying biological patterns. This novel application of DIC in root biology is effective, scalable, low cost, flexible and complementary to existing technologies. This method offers a new tool for answering questions in plant biology and will be particularly useful in studies involving temporal dynamics of root processes. PMID- 29453935 TI - Evaluation of cerebrospinal fluid phosphorylated tau231 as a biomarker in the differential diagnosis of Alzheimer's disease and vascular dementia. AB - BACKGROUND: The diagnosis of either Alzheimer's disease (AD) or vascular dementia (VaD) is still largely based on clinical guidelines and exclusion of other diseases that may lead to dementia. AIMS: In this study, we assessed whether the use of sensitive and specific biomarkers such as phosphorylated tau proteins could contribute to an earlier and more accurate diagnosis of AD and VaD, as well as to their differentiation. MATERIAL AND METHODS: A total of 198 patients, of which 152 had AD, 28 VaD, and 18 were healthy controls (HC), were included in the analyses. We analyzed cerebrospinal fluid (CSF) levels of total tau protein (t tau), tau protein phosphorylated at threonine 231 (p-tau231), and factor score (FS) determined by combination of p-tau231 and Mini-Mental State Examination (MMSE) in patients with AD and VaD, as well as in HC. We tested the diagnostic accuracy of these biomarkers in the CSF and FS (p-tau231, MMSE) in differentiating AD from VaD and HC. RESULTS: Total tau levels were significantly elevated in subjects with AD compared to HC, as well as in VaD subjects compared to HC. DISCUSSION: p-tau231 levels were significantly higher in patients with ADvsHC as well in patients with VaD vsHC. p-tau231 levels did not distinguish AD from VaD patients. Importantly, FS(p-tau231 and MMSE) showed statistically significant differences in the distribution of subjects with AD and VaD. CONCLUSION: These results indicate that FS (p-tau231 and MMSE) has a strong potential to provide an early distinction between AD and VaD. PMID- 29453934 TI - Distinct domains of the AVRPM3A2/F2 avirulence protein from wheat powdery mildew are involved in immune receptor recognition and putative effector function. AB - Recognition of the AVRPM3A2/F2 avirulence protein from powdery mildew by the wheat PM3A/F immune receptor induces a hypersensitive response after co expression in Nicotiana benthamiana. The molecular determinants of this interaction and how they shape natural AvrPm3a2/f2 allelic diversity are unknown. We sequenced the AvrPm3a2/f2 gene in a worldwide collection of 272 mildew isolates. Using the natural polymorphisms of AvrPm3a2/f2 as well as sequence information from related gene family members, we tested 85 single-residue-altered AVRPM3A2/F2 variants with PM3A, PM3F and PM3FL456P/Y458H (modified for improved signaling) in Nicotiana benthamiana for effects on recognition. An intact AvrPm3a2/f2 gene was found in all analyzed isolates and the protein variant recognized by PM3A/F occurred globally at high frequencies. Single-residue alterations in AVRPM3A2/F2 mostly disrupted, but occasionally enhanced, the recognition response by PM3A, PM3F and PM3FL456P/Y458H . Residues enhancing hypersensitive responses constituted a protein domain separate from both naturally occurring polymorphisms and positively selected residues of the gene family. These results demonstrate the utility of using gene family sequence diversity to screen residues for their role in recognition. This approach identified a putative interaction surface in AVRPM3A2/F2 not polymorphic in natural alleles. We conclude that molecular mechanisms besides recognition drive AvrPm3a2/f2 diversification. PMID- 29453937 TI - Trajectory classes of cannabis use and heavy drinking among rural African American adolescents: multi-level predictors of class membership. AB - AIMS: To inform research on the etiology and prevention of substance use among rural African American youth by (a) identifying developmental trajectory classes of cannabis use and heavy drinking across adolescence and young adulthood and (b) examining associations between trajectory class membership and multi-level assessments of risk factors. DESIGN: A prospective study spanning 9 years with assessments of cannabis use and heavy drinking, the catecholamines epinephrine and norepinephrine, perceived stress and psychosocial risk factors. SETTING: Rural communities in the southeastern United States. PARTICIPANTS: African American youth (n = 518). MEASUREMENTS: Participants were assessed for cannabis use and heavy drinking at seven assessments beginning at 16 years of age and continuing to 25 years of age. At age 19, participants provided overnight urine voids that were assayed for catecholamines, a biological marker of life stress resulting from sympathetic nervous system activation. At ages 16 and 19, participants provided information on malleable psychosocial risk factors. FINDINGS: Latent class growth models revealed three distinct trajectory classes for cannabis use and for heavy drinking. Higher levels of circulating stress hormones and perceived stress were associated with classes reporting greater substance use over time (all Ps < 0.05). A composite of selected risk factors discriminated class membership (all Ps < 0.05). Trajectory classes characterized by rapid usage increases in early adulthood exhibited the greatest increase in deviant peer affiliations between ages 16 and 19 years. CONCLUSIONS: Rural African American youth's cannabis use and heavy drinking across adolescence and young adulthood demonstrate distinct developmental courses; a small number of risk factors and measures of biological and perceived stress differentiate class membership prognostically. Variability over time in these measures, specifically an increase in deviant peer affiliation, may help to account for steep increases in young adulthood. PMID- 29453938 TI - Barley stripe mosaic virus infection requires PKA-mediated phosphorylation of gammab for suppression of both RNA silencing and the host cell death response. AB - The Barley stripe mosaic virus (BSMV) gammab protein is a viral suppressor of RNA silencing (VSR) and symptom determinant. However, it is unclear how post translational modification affects the different functions of gammab. Here, we demonstrate that gammab is phosphorylated at Ser-96 by a PKA-like kinase in vivo and in vitro. Mutant viruses containing a nonphosphorylatable substitution (BSMVS96A or BSMVS96R ) exhibited reduced viral accumulation in Nicotiana benthamiana due to transient induction of the cell death response that constrained the virus to necrotic areas. By contrast, a BSMVS96D mutant virus that mimics gammab phosphorylation spread similarly to the wild-type virus. Furthermore, the S96A mutant had reduced local and systemic gammab VSR activity due to having compromised its binding activity to 21-bp dsRNA. However, overexpression of other VSRs in trans or in cis failed to rescue the necrosis induced by BSMVS96A , demonstrating that suppression of cell death by gammab phosphorylation is functionally distinct from its RNA silencing suppressor activities. These results provide new insights into the function of gammab phosphorylation in regulating RNA silencing and the BSMV-induced host cell death response, and contribute to our understanding of how the virus optimizes the balance between viral replication and virus survival in the host plants during virus infection.

PMID- 29453941 TI - Increased Morbidity and Mortality Associated with Falls Among Patients with Cirrhosis. AB - BACKGROUND: Injuries are more morbid and complicated to manage in patients with cirrhosis. However, data are limited regarding the relative risk of injury and severity of injury from falls in patients with cirrhosis compared with those without cirrhosis. METHODS: We examined the nationally representative National Emergency Department Sample, an all-payer database including all patients presenting with falls, 2009-2012. We determined the relative risks for and clinical associations with severe injuries. Outcomes included hospitalization, length of stay, costs, and in-hospital death. Outcomes were compared with those of patients with congestive heart failure. RESULTS: We identified 102,977 visits involving patients with cirrhosis and 26,996,120 involving patients without cirrhosis who presented with a fall. Overall and compared with patients with congestive heart failure, the adjusted risk of severe injury was higher for patients with cirrhosis. These included intracranial hemorrhage (2.33; 95% confidence interval [CI], 2.02-2.68), skull fracture (1.75; 95% CI, 1.53-2.00), and pelvic fracture (1.71; 95% CI, 1.56-1.88). Risk was lower for less-severe injuries, such as concussion (0.95; 95% CI, 0.86-1.06) and lower-leg fracture (0.86; 95% CI, 0.80-0.91). Risk factors significantly positively associated with severe injury on multivariate analysis were hepatic encephalopathy, alcohol abuse, and infection. Cirrhosis was associated with increased risk of in-hospital death, longer length of stay, and higher costs after a fall. All outcomes were worse compared with those for patients with congestive heart failure CONCLUSION: Falls are common in patients with cirrhosis, and they are more likely to incur severe injuries, with increased hospital costs and risk of death. Poor outcomes are most associated with ascites, hepatic encephalopathy, alcohol abuse, and infection, highlighting the subgroups at highest risk and most likely to benefit from preventative interventions. PMID- 29453942 TI - Mobile Thoracolithiasis. PMID- 29453944 TI - Clinical Features of Extrapulmonary Sarcoidosis Without Lung Involvement. AB - BACKGROUND: Compared with pulmonary sarcoidosis, sarcoidosis without lung involvement may involve other immunopathologic mechanisms and be associated with other demographic and clinical features. METHODS: This was a retrospective analysis of clinical data collected in real time on 1,686 patients with biopsy proven sarcoidosis from two large university sarcoidosis outpatient clinics in the United States. We compared differences in demographics characteristics and clinical presentation between pulmonary and nonpulmonary sarcoidosis (NPS). Patients were considered to have NPS only if they had normal chest imaging and no features consistent with pulmonary involvement on the basis of currently accepted criteria. RESULTS: A total of 8.3% of this sarcoidosis cohort met criteria for NPS. NPS was significantly more common in white than black patients, and more common in women than men. The skin was the most common organ involved, and was observed in nearly one-half of patients with NPS. Isolated skin sarcoidosis was the overwhelmingly most common pattern of organ involvement seen in the NPS group (25%), and no other pattern of involvement was found in more than 5% of patients with NPS. CONCLUSIONS: Significant demographic and sex differences were observed between patients with pulmonary and nonpulmonary sarcoidosis. These differences reflect previous data concerning differences between patients with skin and lung sarcoidosis because the skin was the major organ involved with NPS. Although the lungs are likely the primary site of exposure in pulmonary sarcoidosis, the high prevalence of skin involvement in NPS suggests the skin is the most conducive site of antigen capture outside of the respiratory tract. PMID- 29453945 TI - Evaluation of lipid peroxidation and antioxidant defense mechanisms in the bone of rats in conditions of separate and combined administration of vanadium (V) and magnesium (Mg). AB - The impact of vanadium (V) and magnesium (Mg) applied as sodium metavanadate (SMV, 0.125 mg V/ml) and magnesium sulfate (MS, 0.06 mg Mg/ml) on oxidative stress markers in bone of male Wistar rats was investigated. Some of them were also measured in the liver, e.g. l-ascorbic acid (hepatic L-AA). Additionally, relationships between selected indices determined in bone were examined. SMV alone (Group II) did not significantly alter the level of TBARS and the activity of SOD, compared with the control (Group I), but it slightly reduced the GR activity (by 13%) and the L-AA level (by 15.5%). It also markedly lowered the activity of CAT and GPx (by 34% and 29%), and to some degree elevated the activity of GST (by 16%) and the hepatic L-AA level (by 119%). MS alone (Group III) decreased the TBARS level (by 49%), slightly lowered the L-AA concentration (by 14%), and reduced the SOD, GPx, and GR activities (by 31%, 40%, and 28%), but did not change the activity of CAT, compared with the control. Additionally, it elevated the GST activity (by 56%) and the hepatic L-AA level (by 40%). In turn, the SMV + MS combination (Group IV) reduced the TBARS level (by 38%) and the SOD, CAT, GPx, and GR activities (by 61%, 58%, 72%, and 40%) but elevated the GST activity (by 66%), compared with the control. The activity of SOD and GPx in the rats in Group IV was also reduced, compared with Group II (by 61% and 61%) and Group III (by 44% and 54%). In turn, the activities of CAT and GR were decreased, compared with Group III (by 55%) and Group II (by 31%), and the L-AA level was lowered, in comparison with Groups II and III (by 53% and 54%). Further, the concentration of V in the bone of rats in Groups II and IV increased, whereas the concentration of Mg decreased, compared with Groups I and III, in which the V and Mg levels dropped and were not altered, respectively, compared with Group I. The total content of Fe in the bone of rats in Groups II and IV increased, compared with Group III, in which the total Fe content did not change, compared with Group I. In turn, the total bone Cu content significantly decreased in the rats in Groups III and IV, compared with Groups I and II, whereas the total Zn content and the Ca concentration did not change markedly. The results provided evidence that the concentration of V used as SMV did not enhance LPO in bone, whereas Mg, at the selected level, markedly reduced LPO in this tissue. On the other hand, both elements administered separately and in combination disrupted the antioxidant defense mechanisms and homeostasis of some metals in bone tissue, which consequently may have contributed to disturbances in the balance in the activities of osteoblastic and osteoclastic cells, and thereby negatively affected bone health. PMID- 29453946 TI - The sexual and reproductive health of foreign-born women in the United States. AB - OBJECTIVE: To explore the sexual and reproductive health (SRH) behaviors, health insurance coverage and use of SRH services of women in the United States (U.S.) by nativity, disaggregated by race and ethnicity. STUDY DESIGN: We analyzed publicly available and restricted data from the National Survey of Family Growth to assess differences and similarities between foreign-born and U.S.-born women, both overall and within Hispanic, non-Hispanic (NH) white, NH black and NH Asian groups. RESULTS: A larger proportion of foreign-born women than U.S.-born women lacked health insurance coverage. Foreign-born women utilized SRH services at lower rates than U.S.-born women; this effect diminished at the multivariate level, although race and ethnicity differences remained. Overall, foreign-born women were less likely to pay for SRH services with private insurance than U.S. born women. Foreign-born women were less likely to use the most effective contraceptive methods than U.S.-born women, with some variation across race and ethnicity: NH white and NH black foreign-born women were less likely to use highly effective contraceptive methods than their U.S.-born counterparts, but among Hispanic women, the reverse was true. CONCLUSION: Our findings demonstrate that the SRH behaviors, needs and outcomes of foreign-born women differ from those of U.S-born women within the same race/ethnic group. IMPLICATIONS: This paper contributes to the emergent literature on immigrants in the U.S. by laying the foundation for further research on the SRH of the foreign-born population in the country, which is critical for developing public health policies and programs to understand better and serve this growing and diverse population. PMID- 29453947 TI - Evaluation of the effects of RP5063, a novel, multimodal, serotonin receptor modulator, as single-agent therapy and co-administrated with sildenafil, bosentan, and treprostinil in a monocrotaline-induced pulmonary arterial hypertension rat model. AB - Pulmonary arterial hypertension (PAH), a condition that is defined by pulmonary vasculature constriction and remodeling, involves dysfunctional signaling of the serotonin (5-HT) receptors, 5-HT2A/2B/7. In a rat model of monocrotaline (MCT) induced PAH, the effectiveness of RP5063 (RP), a dopamine and 5-HT receptor modulator, was evaluated as monotherapy and as an adjunct to standard PAH treatments. After a single 60 mg/kg dose of MCT, rats received vehicle (MCT+Veh; gavage twice-daily [b.i.d.]), RP (10 mg/kg; gavage b.i.d.), bosentan (B; 100 mg/kg; gavage BID), sildenafil (S; 50 mg/kg; gavage, BID), treprostinil (T; 100 ng/kg/min over 24 h intravenous), RP+B, RP+S, and RP+T for 28 days. Single-agent RP limited the functional and structural effects of PAH seen in the MCT+Veh group, with significant improvements in pulmonary hemodynamics, right ventricular (RV) hypertrophy, SO2, and pulmonary blood vessel structural changes. These effects appeared comparable with those associated with B, S, and T. Adjunctive RP treatment resulted in significantly lower mean pulmonary arterial pressures, RV systolic pressure. It also improved SO2 measurements, as compared with MCT+Veh (P < 0.05), and diastolic pulmonary artery pressure (P < 0.05), as compared with single-agent B and S therapy (Bonferroni method adjusting for multiplicity). RP+S appeared to show the most consistent and extensive effects on pulmonary hemodynamics, respiratory parameters, and histopathologic changes. These results corroborate earlier preclinical findings supporting the efficacy of single-agent RP in PAH. RP, as mono and adjunctive therapy compared with induced-control, mitigated the functional and structural effects of MCT-induced PAH.

PMID- 29453948 TI - Noncritical Signaling Role of a Kinase-Receptor Interaction Surface in the Escherichia coli Chemosensory Core Complex. AB - In Escherichia coli chemosensory arrays, transmembrane receptors, a histidine autokinase CheA, and a scaffolding protein CheW interact to form an extended hexagonal lattice of signaling complexes. One interaction, previously assigned a crucial signaling role, occurs between chemoreceptors and the CheW-binding P5 domain of CheA. Structural studies showed a receptor helix fitting into a hydrophobic cleft at the boundary between P5 subdomains. Our work aimed to elucidate the in vivo roles of the receptor-P5 interface, employing as a model the interaction between E. coli CheA and Tsr, the serine chemoreceptor. Crosslinking assays confirmed P5 and Tsr contacts in vivo and their strict dependence on CheW. Moreover, the P5 domain only mediated CheA recruitment to polar receptor clusters if CheW was also present. Amino acid replacements at CheA.P5 cleft residues reduced CheA kinase activity, lowered serine response cooperativity, and partially impaired chemotaxis. Pseudoreversion studies identified suppressors of P5 cleft defects at other P5 groove residues or at surface-exposed residues in P5 subdomain 1, which interacts with CheW in signaling complexes. Our results indicate that a high-affinity P5-receptor binding interaction is not essential for core complex function. Rather, P5 groove residues are probably required for proper cleft structure and/or dynamic behavior, which likely impact conformational communication between P5 subdomains and the strong binding interaction with CheW that is necessary for kinase activation. We propose a model for signal transmission in chemotaxis signaling complexes in which the CheW-receptor interface plays the key role in conveying signaling-related conformational changes from receptors to the CheA kinase. PMID- 29453943 TI - MAPK and PI3K signaling: At the crossroads of neural crest development. AB - Receptor tyrosine kinase-mediated growth factor signaling is essential for proper formation and development of the neural crest. The many ligands and receptors implicated in these processes signal through relatively few downstream pathways, frequently converging on the MAPK and PI3K pathways. Despite decades of study, there is still considerable uncertainty about where and when these signaling pathways are required and how they elicit particular responses. This review summarizes our current understanding of growth factor-induced MAPK and PI3K signaling in the neural crest. PMID- 29453950 TI - Towards elimination of schistosomiasis after 5000 years of endemicity in Egypt. AB - Schistosomiasis is a snail-transmitted infectious disease caused by a long lasting infection with a blood fluke of the genus Schistosoma. S. haematobium and S. mansoni are the species endemic in Egypt. The country has been plagued and seriously suffered from schistosomiasis over the past 5000 years. Great strides had been done in controlling the disease since 1922. The history, epidemiology and the different control approaches were reviewed. Currently, Egypt is preparing towards schistosomiasis elimination by 2020. The new strategy depends on four main axes; large scale treatment in all areas of residual transmission by targeting entire populations with PZQ, intensified snail control, heath education and behavioral changes and expansion of the complementary public health interventions. While on the road towards elimination, we addressed here the important challenges, lessons and the key issues from the different control strategies to help the achievement of our goal. Notably, frangibility of the drug based control, emergence of resistance against PZQ, persistence of some hot spots areas, the need of further control efforts to the high risk individuals and community involvement in the control programs, reconsideration of diagnostic tests used in surveillance, and continous monitoring of the field to detect changes in the snail intermediate host. Importantly, the adaptation between the parasite and its intermediate snail host throughout water bodies in Egypt merits attention as Schistosoma infection can be introduced to the new reclaimed areas. This review may help supplying information for the policy makers to tailor control measures suitable to the local context that could help in the transfer from control to elimination.

AB - HMGB1 and HMGB2 are DNA-interacting proteins but can also have extracellular actions during inflammation. Despite their relatively high homology, they may have distinct roles, making it essential to be able to differentiate between the two. Here we examine the specificity of five commercially-available anti-HMGB1 antibodies. By Western blotting of recombinant proteins and HMGB1-/- mouse embryonic fibroblasts, we identified only one HMGB1 antibody that, under our experimental conditions, did not also detect HMGB2. Selecting specific antibodies for HMGB1 and HMGB2 allowed identification of distinct HMGB1 and HMGB2 subcellular pools in primary neutrophils. PMID- 29453956 TI - Frequent mutations of RetNet genes in eoHM: Further confirmation in 325 probands and comparison with late-onset high myopia based on exome sequencing. AB - In our previous study, potential pathological mutations of RetNet genes were detected in 23.8% (71/298) of probands with early-onset high myopia (eoHM), based on whole exome sequencing (WES). The current study aimed to confirm this finding in an additional 325 probands with eoHM and to clarify its specificity by comparison of 195 probands with late-onset high myopia (loHM). Variants in the 234 RetNet genes were selected from whole-exome sequencing data and were filtered using multistep bioinformatics analyses. Potential pathological variants in 33 genes were detected in 76 of 325 (23.4%) probands with eoHM and 14 of 195 (7.2%) probands with loHM. Thirty-five of the 76 (46.1%) probands with eoHM had mutations in COL2A1, COL11A1, RPGR, and CACNAIF, while only 2/14 (14.3%) probands with eoHM were detected. The mutation frequency and spectrum of RetNet genes in the 325 probands with eoHM were similar to our previous study but were significantly different in 195 probands with loHM (P = 2 * 10-6 and 0.04). Data from eoHM and loHM strongly suggest that a significant proportion of eoHM is caused by mutations in RetNet genes. These results also provide initial genetic evidence that eoHM is different from loHM. The presence of mutations in 7.2% probands with loHM raises questions about pathogenicity and the variable manifestation of some mutations. The functional studies of the mutations in question and more extensive investigations of related phenotypes in the mutation carriers and their family members may provide valuable information to address these questions.

The duration of a sensory stimulus is one of its defining attributes, but it is not clear how this is encoded in the brain. This work explores whether the duration of a visual stimulus is an attribute that the brain can automatically adapt to and use to predict future stimulus durations. Visual mismatch negativity (vMMN) is an ERP component elicited, even when the stimuli are unattended, when an 'unexpected' visual stimulus appears amongst a series of expected stimuli in an 'oddball' paradigm. As such vMMN has been suggested to show that the violation of a pattern in a sequence has been automatically detected. To date, vMMN has only been measured to differences in the visual durations of static on/off stimuli, placed near to the centre of the visual field. Our study measures vMMN to test whether duration is encoded automatically for static stimuli against a blank background and moving stimuli against a static background, whilst attention is directed to a different spatial location using a continuous, attention demanding task. VMMN elicited in response to the shorter duration for both stimuli shows that the brain detects the differences of duration even in the absence of focussed spatial attention. For the motion stimulus a larger difference in duration was needed. We conclude that duration is encoded automatically in the visual cortex and is an attribute that can be adapted to, and form the basis of predictions. PMID- 29453958 TI - Age-dependent effects of dimethyl fumarate on cognitive and neuropathological features in the streptozotocin-induced rat model of Alzheimer's disease. AB - We previously demonstrated that dimethyl fumarate (DMF), an anti-oxidative and immunosuppresive compound, prevents intracerebroventricular (ICV) streptozotocin induced disruption of spatial memory and neurodegeneration in 4-month-old rats. The present study evaluated the influence of age on DMF's therapeutic effect. Aged rats (22-months-old, n = 40) were provided rodent chow containing DMF (0.4%) and given ICV injections of streptozotocin (STZ) or vehicle (Sham) on days 2 and 4. Spatial memory was evaluated using the Morris water maze (MWM) on days 14-21. Hippocampal samples from young (4-month-old, n = 36, collected previously) and aged rats were assessed for presence of activated (CD68-positive) microglia, IL 10 and oxidative/nitrative stress marker nitrotyrosine. Aged rat samples were also stained with Fluoro-JadeB marker for neurodegeneration. Previously obtained MWM and Fluoro-JadeB data from young rats served as a reference for assessing impact of age. Aged Sham DMF-fed rats exhibited better spatial memory and less neurodegeneration in the CA3 region of the hippocampus compared to corresponding young rats. Aged STZ rats displayed greater memory impairment and increased CA2 neurodegeneration, CA1 nitrotyrosine immunoreactivity, and microglial activation in the dentate gyrus (DG), compared to young STZ rats. Notably, within aged STZ injected rats, DMF treatment was associated with improved performance in MWM, reduced neurodegeneration in all hippocampal areas, reduced DG microglia activation, and reduced CA1 nitrotyrosine labeling compared to age-matched rats without DMF treatment. This beneficial age-related effect of DMF treatment after STZ ICV injections may result from reduced microglial activation in the hippocampus that leads to an alleviation of oxidative stress, neurodegeneration, and memory impairments. PMID- 29453959 TI - Indices of repetitive behaviour are correlated with patterns of intrinsic functional connectivity in youth with autism spectrum disorder. AB - The purpose of the current study was to examine how repetitive behaviour in Autism Spectrum Disorder (ASD) is related to intrinsic functional connectivity patterns in a number of large-scale, neural networks. Resting-state fMRI scans from thirty subjects with ASD and thirty-two age-matched, typically developing control subjects were analysed. Seed-to-voxel and ROI-to-ROI functional connectivity analyses were used to examine resting-state connectivity in a number of cortical and subcortical neural networks. Bivariate correlation analysis was performed to examine the relationship between repetitive behaviour scores from the Repetitive Behaviour Scale - Revised and intrinsic functional connectivity in ASD subjects. Compared to control subjects, ASD subjects displayed marked over connectivity of the thalamus with several cortical sensory processing areas, as well as over-connectivity of the basal ganglia with somatosensory and motor cortices. Within the ASD group, significant correlations were found between functional connectivity patterns and total RBS-R scores as well as one principal component analysis-derived score from the RBS-R. These results suggest that thalamocortical resting-state connectivity is altered in individuals with ASD, and that resting-state functional connectivity is associated with ASD symptomatology. PMID- 29453962 TI - An Autoantibody Against Human DNA-Topoisomerase I Is a Novel Biomarker for Non Small Cell Lung Cancer. AB - BACKGROUND: We previously reported a novel tumor-associated antigen with a molecular weight of approximately 48 kDa that was a fragment derived from human DNA-topoisomerase I. The aim of this study is to further investigate the clinical significance of the autoantibody in patients with non-small cell lung cancer (NSCLC). METHODS: We determined serum levels of the autoantibody in 127 NSCLC patients, 127 age-, sex-, and smoking history-matched healthy control subjects, and 38 patients with pulmonary benign tumors by using a specific enzyme linked immunosorbent assay for the autoantibody. We then statistically evaluated its clinical application value. RESULTS: Serum levels of the autoantibody in NSCLC patients were significantly higher than in healthy control subjects and patients with benign tumors (p = 0.001). The percentage of sera with a positive level of the autoantibody was 71.8%, 65.6%, 41.9%, and 48.0% in stages I, II, III, and IV of the cancer, respectively (p = 0.049). The area under the receiver-operating characteristics curve was 0.971 (95% confidence interval: 0.953 to 0988) for healthy controls and patients with benign tumors versus early stage NSCLC patients. Moreover, the overall survival rate of the patients in stages I, II, and IV with negative levels of the autoantibody was significantly lower than that of patients with positive levels of the autoantibody (p = 0.013, 0.023, and 0.047 for stages I, II, and IV, respectively). CONCLUSIONS: Our results indicate that the autoantibody can be used as a novel biomarker for the early diagnosis and prognosis of NSCLC. PMID- 29453963 TI - Significance of Spread Through Air Spaces in Resected Pathological Stage I Lung Adenocarcinoma. AB - BACKGROUND: "Spread through air spaces" (STAS) is a recently described invasive pattern of lung cancer that spreads within air spaces beyond the edge of the main tumor. In the current study, we investigated the significance of STAS in patients with pathologic stage I adenocarcinoma. METHODS: We assessed STAS in a total of 276 patients with resected pathologic stage I adenocarcinoma. STAS was classified as either no STAS, low STAS (1-4 single cells or clusters of STAS), or high STAS (>=5 single cells or clusters of STAS) using a 20x objective and a 10x ocular lens. We evaluated the association between STAS and the clinicopathologic characteristics and postoperative survivals. RESULTS: Among 276 patients, 123 (44.6%), 48 (17.4%), and 105 (38.0%) were classified as having no, low, and high STAS, respectively. The positivity for STAS was significantly associated with larger radiologic tumor diameter (p = 0.008), higher consolidation/tumor ratio (p < 0.001), higher maximum standard uptake value (p < 0.001), pathologically larger tumor size (p = 0.004), pleural invasion (p = 0.027), and histologically invasive type (p < 0.001); whereas STAS was not significantly associated with epidermal growth factor receptor mutations or programmed death ligand-1 expression (p = 0.129 and p = 0.872, respectively). Patients with STAS had significantly shorter recurrence-free and overall survival than patients without STAS (p < 0.001 and p = 0.002, respectively). According to a multivariate analysis, positivity for STAS remained an independent prognostic factor for both recurrence-free survival and overall survival. CONCLUSIONS: Spread through air spaces was associated with clinicopathologically invasive features and was predictive of worse survival. PMID- 29453961 TI - Repeat-associated non-AUG (RAN) translation and other molecular mechanisms in Fragile X Tremor Ataxia Syndrome. AB - Fragile X-associated tremor/ataxia syndrome (FXTAS) is a late-onset inherited neurodegenerative disorder characterized by progressive intention tremor, gait ataxia and dementia associated with mild brain atrophy. The cause of FXTAS is a premutation expansion, of 55 to 200 CGG repeats localized within the 5'UTR of FMR1. These repeats are transcribed in the sense and antisense directions into mutants RNAs, which have increased expression in FXTAS. Furthermore, CGG sense and CCG antisense expanded repeats are translated into novel proteins despite their localization in putatively non-coding regions of the transcript. Here we focus on two proposed disease mechanisms for FXTAS: 1) RNA gain-of-function, whereby the mutant RNAs bind specific proteins and preclude their normal functions, and 2) repeat-associated non-AUG (RAN) translation, whereby translation through the CGG or CCG repeats leads to the production of toxic homopolypeptides, which in turn interfere with a variety of cellular functions. Here, we analyze the data generated to date on both of these potential molecular mechanisms and lay out a path forward for determining which factors drive FXTAS pathogenicity. PMID- 29453960 TI - Synaptic dysfunction and altered excitability in C9ORF72 ALS/FTD. AB - Amyotrophic lateral sclerosis (ALS) is characterized by a progressive degeneration of upper and lower motor neurons, resulting in fatal paralysis due to denervation of the muscle. Due to genetic, pathological and symptomatic overlap, ALS is now considered a spectrum disease together with frontotemporal dementia (FTD), the second most common cause of dementia in individuals under the age of 65. Interestingly, in both diseases, there is a large prevalence of RNA binding proteins (RBPs) that are mutated and considered disease-causing, or whose dysfunction contribute to disease pathogenesis. The most common shared genetic mutation in ALS/FTD is a hexanucleuotide repeat expansion within intron 1 of C9ORF72 (C9). Three potentially overlapping, putative toxic mechanisms have been proposed: loss of function due to haploinsufficient expression of the C9ORF72 mRNA, gain of function of the repeat RNA aggregates, or RNA foci, and repeat associated non-ATG-initiated translation (RAN) of the repeat RNA into toxic dipeptide repeats (DPRs). Regardless of the causative mechanism, disease symptoms are ultimately caused by a failure of neurotransmission in three regions: the brain, the spinal cord, and the neuromuscular junction. Here, we review C9 ALS/FTD-associated synaptic dysfunction and aberrant neuronal excitability in these three key regions, focusing on changes in morphology and synapse formation, excitability, and excitotoxicity in patients, animal models, and in vitro models. We compare these deficits to those seen in other forms of ALS and FTD in search of shared pathways, and discuss the potential targeting of synaptic dysfunctions for therapeutic intervention in ALS and FTD patients. PMID- 29453964 TI - Conidiogenesis-related DNA photolyase gene in Beauveria bassiana. AB - Beauveria bassiana is an entomopathogenic fungi used in environmentally mindful pest management. Its main active ingredient, conidia, is commercially available as a fungal biopesticide. Many studies of conidia production have focused on how to optimize culture conditions for maximum productivity and stability against unfavorable abiotic factors. However, understanding of how conidiogenesis-related genes provide improved conidial production remains unclear. In this study, we focus on identifying conidiogenesis-related genes in B. bassiana ERL1170 using a random mutagenesis technique. Transformation of ERL1170 using restriction enzyme mediated integration generated one morphologically different transformant, ERL1170-pABeG #163. The transformant was confirmed to represent B. bassiana, and the binary vector was successfully integrated into the genome of ERL1170. Compared to the wild type, transformant #163 showed very slow hyphal growth and within 6 days only produced <1 * 106 conidia/0.28 cm2 agar block (wild type: 6.2 * 107 conidia/agar block). Transformant #163 also exhibited different morphology than the wild type, including thicker hyphae with some club-shaped parts. In contrast, the typical morphology of wild type B. bassiana exhibits thread-like hyphae and conidiophore structures and circular conidia. To determine the location of the randomly inserted DNA, we conducted thermal asymmetric interlaced (TAIL) PCR and Escherichia coli cloning to clearly sequence the disrupted region. We identified one colony (colony No. 7) with an insertion site identified as DNA photolyase. This was confirmed through a gene knock-out study. It is possible the gene that encodes for DNA photolyase was disrupted during the insertion process and might be involved in fungal conidiogenesis. This work serves as a platform for exploring the function of a variety of B. bassiana genes involved in pest management and their downstream processing. PMID- 29453965 TI - Effects of Beauveria bassiana on predation and behavior of the predatory mite Phytoseiulus persimilis. AB - Determination of intraguild interactions between entomopathogens and predators is important when attempting to use a combination of these two natural enemy groups for biological control of their shared arthropod pest species. This study assessed the effects of Beauveria bassiana on the predation and associated behavior of the predatory mite, Phytoseiulus persimilis, against Tetranychus urticae. The functional response tests showed that P. persimilis exhibited a Holling type II response on the spider mite, Tetranychus urticae, when treated with either a B. bassiana or Tween-80 suspension. There were no significant differences between the treatments in the number of T. urticae consumed. The laboratory choice test indicated that P. persimilis displayed a significant avoidance response to B. bassiana on bean leaves immediately following spray application. They also spent significantly longer time in self-grooming behavior on leaf disks sprayed with fungal conidia than on discs treated with Tween-80. There were no significant differences in the predation rates on T. urticae eggs between the different treatments. The potted plant investigations indicated that P. persimilis showed significant aversion behavior to the initial fungal spray, but gradually dispersed over the entire bean plants. Observations using scanning electron microscopy revealed that fungal conidia were attached to the body of P. persimilis after mounting the leaf disk treated with B. bassiana, which would account for its varied behavioral responses. Our study suggests that fungal spray did not affect the predation capability of P. persimilis and poses a negligible risk to their behavior. PMID- 29453966 TI - Gamma irradiation inactivates honey bee fungal, microsporidian, and viral pathogens and parasites. AB - Managed honey bee (Apis mellifera) populations are currently facing unsustainable losses due to a variety of factors. Colonies are challenged with brood pathogens, such as the fungal agent of chalkbrood disease, the microsporidian gut parasite Nosema spp., and several viruses. These pathogens may be transmitted horizontally from worker to worker, vertically from queen to egg and via vectors like the parasitic mite, Varroa destructor. Despite the fact that these pathogens are widespread and often harbored in wax comb that is reused from year to year and transferred across beekeeping operations, few, if any, universal treatments exist for their control. In order to mitigate some of these biological threats to honey bees and to allow for more sustainable reuse of equipment, investigations into techniques for the sterilization of hive equipment and comb are of particular significance. Here, we investigated the potential of gamma irradiation for inactivation of the fungal pathogen Ascosphaera apis, the microsporidian Nosema ceranae and three honey bee viruses (Deformed wing virus [DWV], Black queen cell virus [BQCV], and Chronic bee paralysis virus [CBPV]), focusing on the infectivity of these pathogens post-irradiation. Results indicate that gamma irradiation can effectively inactivate A. apis, N. ceranae, and DWV. Partial inactivation was noted for BQCV and CBPV, but this did not reduce effects on mortality at the tested, relatively high doses. These findings highlight the importance of studying infection rate and symptom development post-treatment and not simply rate or quantity detected. These findings suggest that gamma irradiation may function as a broad treatment to help mitigate colony losses and the spread of pathogens through the exchange of comb across colonies, but raises the question why some viruses appear to be unaffected. These results provide the basis for subsequent studies on benefits of irradiation of used comb for colony health and productivity. PMID- 29453967 TI - Discovery of anti-viral molecules and their vital functions in Bombyx mori. AB - The silkworm Bombyx mori (B. mori), a lepidopteran model organism, has become an important model for molecular biology researches with its genome completely sequenced. Silkworms confront different types of virus diseases, mainly including those caused by Bombyx mori nucleopolyhedrovirus (BmNPV), Bombyx mori densovirus type 1 (BmDNV-1), Bombyx mori bidesovirus (BmBDV) which was termed as Bombyx mori densovirus type 2 (BmDNV-2) or Bombyx mori parvo-like virus (BmPLV) before in sericulture. B. mori offers excellent models to study the molecular mechanisms of insect innate immune responses to viruses. A variety of molecules and pathways have been identified to be involved in the immune responses in the silkworm to viruses, such as the antimicrobial peptides, prophenoloxidase-activating system, apoptosis, ROS, small RNA and related molecules. Here in this review, we summarize the current research advances in molecules involved in silkworm anti virus pathways. Moreover, taking BmNPV as an example, we proposed a schematic model of molecules and pathways involved in silkworm immune responses against virus infection. We hope this review can facilitate further study of antiviral mechanisms in silkworm, and provide a reference for virus diseases in other organisms. PMID- 29453968 TI - Lipoprotein lipase: Biosynthesis, regulatory factors, and its role in atherosclerosis and other diseases. AB - Lipoprotein lipase (LPL) is a rate-limiting enzyme that catalyzes hydrolysis of the triglyceride (TG) core of circulating TG-rich lipoproteins including chylomicrons (CM), low-density lipoproteins (LDL) and very low-density lipoproteins (VLDL). A variety of parenchymal cells can synthesize and secrete LPL. Recent studies have demonstrated that complicated processes are involved in LPL biosynthesis, secretion and transport. The enzyme activity of LPL is regulated by many factors, such as apolipoproteins, angiopoietins, hormones and miRNAs. In this article, we also reviewed the roles of LPL in atherosclerosis, coronary heart disease, cerebrovascular accident, Alzheimer disease and chronic lymphocytic leukemia. LPL in different tissues exerts differential physiological functions. The role of LPL in atherosclerosis is still controversial as reported in the literature. Here, we focused on the properties of LPL derived from macrophages, endothelial cells and smooth muscle cells in the vascular wall. We also explore the existence of crosstalk between LPL and those cells when the molecule mainly plays a proatherogenic role. This review will provide insightful knowledge of LPL and open new therapeutic perspectives. PMID- 29453969 TI - S100 proteins in oral squamous cell carcinoma. AB - BACKGROUND: Controversy exists in the literature regarding the differential expression of S100 protein members and their functional correlations in oral squamous cell carcinoma (OSCC). The aim of the present study was to systematically review the expression of S100 protein family members among OSCC and healthy controls and to evaluate whether S100 protein members serve as diagnostic marker in OSCC. METHODS: Indexed databases were searched up to and including October 2017. Case-control/cross-sectional studies in human diagnosed clinically and/or histologically with OSCC and evaluated the expression of S100 protein family among OSCC and healthy controls were included. RESULTS: A total of 11 studies were included. Four studies were of good quality, 5 were of moderate and 2 were of poor quality. Five studies evaluated S100A2, A7 and A12 and showed overexpression of these protein levels in OSCC patients when compared to healthy controls. Three studies reported down-regulation of S100A1, A3, A6, A11, A13, A14, A16 and S100Z in OSCC patients as compared to healthy controls. Two studies reported overexpression of S100A9 and one study each reported overexpression of S100A4, A8, A10, and S100P in OSCCs as compared to healthy controls respectively. CONCLUSION: It remains debatable whether up-regulation or down-regulation of specific S100 protein members serves as a diagnostic marker in OSCC. With the findings of the present systematic review, the threshold for diagnostic levels of S100 proteins cannot be proposed. In addition, S100A7 protein could act as a potential OSCC marker. However, further case-control studies with larger sample size are required to obtain strong conclusion in this regard. PMID- 29453970 TI - Proton NMR based serum metabolic profile correlates with the neurological recovery in treated acute spinal cord injury (ASCI) subjects: A pilot study. AB - BACKGROUND: Acute Spinal Cord Injury (ASCI) is still having substantial morbidity and mortality despite of advanced therapeutics. Major obstacles are paucity of monitoring tools or biomarkers for severity determination, recovery and prognostication. A prospective case control pilot study with serum 1H NMR spectroscopic metabolic profiling was carried out to evaluate metabolites perturbations and its relationship with recovery and to see role of stem cells in facilitating neurological recovery. METHODOLOGY: Twenty subjects with ASCI were classified on the basis of therapeutic modality into surgical fixation alone (Group-1, n = 10), stem cell adjuvant (Group-2, n = 10) and healthy controls (Group-0, n = 10). Serum samples were collected at admission (baseline) and after six months (follow-up). NMR data of serum sample were quantified and subjected to Wilcoxon and ANOVA tests. Further validation was performed using supervised OSC PCA and OPLS-DA by incorporating substantial control samples. RESULT: Twenty eight metabolites were identified; well resolved resonances of fifteen metabolites were quantified wherein seven were statistically significant. Predominantly amino acids and ketone bodies played vital role in the differentiation of groups. CONCLUSIONS: Serum NMR spectroscopy reveals certain metabolites perturbations having clear correlation with pattern of recovery in treated ASCI subject. Stem cells treatment group had comparatively effective recovery. PMID- 29453971 TI - Prediction value of serum HBV large surface protein in different phases of HBV infection and virological response of chronic hepatitis B patients. AB - BACKGROUND: Serum HBV large surface protein (HBV-LP) is an envelope protein that has a close relationship with HBV DNA level. This study is to explore the prediction value of HBV-LP in different phase of HBV infection and during antiviral therapy in chronic hepatitis B (CHB) patients. METHODS: A retrospective study was conducted in 2033 individuals, which included 1677 HBV infected patients in different phases and 356 healthy controls. HBV-LP, HBV serum markers and HBV DNA were detected by ELISA, CMIA and qRT-PCR, respectively. 85 CHB patients receiving PegIFNalpha or ETV were divided into virological response (VR) and partial virological response (PVR). The dynamic changes of HBV DNA and HBV-LP were observed. RESULTS: The level of HBV-LP in 2033 individuals was shown as: HBeAg-positive hepatitis > HBeAg-positive infection > HBeAg-negative hepatitis > HBeAg-negative infection > healthy controls. HBV-LP was positive in all patients whose HBV DNA > 1.0E + 06 IU/ml. When HBsAg was <0.05 IU/ml or >1000 IU/ml, HBV DNAs were all negative if HBV-LP < 1.0 S/CO. When HBsAg was between 0.05 IU/ml and 1000 IU/ml, the consistency of HBV-LP with HBV DNA was 100% in case of HBV-LP > 4.0 S/CO in HBeAg-positive patients and HBV-LP > 2.0 S/CO in HBeAg-negative ones. During antiviral therapy, baseline HBV-LP was lower in VR patients than that in PVR patients. The optimal cut-off points to predict VR by baseline HBV-LP were 32.4 and 28.6 S/CO for HBeAg-positive and HBeAg-negative hepatitis patients, respectively. CONCLUSIONS: HBV-LP may be a useful marker for distinguishing the different phases of HBV infection. Moreover, baseline HBV-LP level can be used for predicting VR of CHB patients. PMID- 29453972 TI - Artemin regulates CXCR4 expression to induce migration and invasion in pancreatic cancer cells through activation of NF-kappaB signaling. AB - Pancreatic ductal adenocarcinoma (PDAC) is the most lethal human malignant tumor because of the early onset of local invasion and distant metastasis. Perineural invasion is a prominent characteristic of pancreatic adenocarcinoma, which is a multifactorial process that involves various signaling molecules from different signaling pathways. The glial cell line-derived neurotrophic factor family of ligands was reported to be involved in perineural invasion in pancreatic cancer. Artemin is one member of the glial cell line-derived neurotrophic factor family of ligands. Although Artemin has previously been demonstrated to promote invasiveness of pancreatic cancer, the mechanisms remain poorly understood. In this study, we performed an analysis to determine the effects of Artemin on modulating tumor cell metastatic potential and invasion activity and explored its mechanisms in pancreatic cancer. We indicated that Artemin and CXCR4 were overexpressed in cancer tissues and widely expressed in pancreatic cancer cell lines. We observed that activation of ERK1/2 and Akt in Artemin-treated cells led to enhanced nuclear accumulation of NF-kappaB, which then induced CXCR4 expression. Through regulation of the expression of CXCR4, Artemin functionally promoted the migration and invasion in pancreatic cancer cells. The present study indicated that Artemin induced CXCR4 expression by activating Akt and ERK 1/2/NF kappaB signaling, thereby modulating tumor cell metastatic potential and invasion activity in pancreatic cancer by regulating SDF-1alpha/CXCR4 axis. Artemin might be an effective and potent therapeutic target for pancreatic cancer metastasis, especially in perineural invasion.

PMID- 29453974 TI - Genetically-modified bone mesenchymal stem cells with TGF-beta3 improve wound healing and reduce scar tissue formation in a rabbit model. AB - Extensive scar tissue formation often occurs after severe burn injury, trauma, or as one of complications after surgical intervention. Despite significant therapeutic advances, it is still a significant challenge to manage massive scar tissue formation while also promoting normal wound healing. The goal of this study was to investigate the therapeutic effect of bone mesenchymal stem cells (BMSCs) that were genetically modified to overexpress transforming growth factor beta 3 (TGF-beta3), an inhibitor of myofibroblast proliferation and collagen type I deposition, on full-thickness cutaneous wound healing in a rabbit model. Twenty four rabbits with surgically-induced full-thickness cutaneous wounds created on the external ear (1.5 * 1.5 cm, two wounds/ear) were randomized into four groups: (G1), wounds with no special treatment but common serum-free culture medium as negative controls; (G2), topically-applied recombinant adenovirus, expressing TGF beta3/GFP; (G3), topically-applied BMSCs alone; (G4), topically-applied BMSCs transfected with Ad-TGF-beta3/GFP (BMSCsTGF-beta3); and (G5), an additional normal control (n = 2) with neither wound nor treatment on the external ear skin. The sizes of wounds on the ear tissues were grossly examined, and the scar depth and density of wounds were histologically evaluated 21, 45, and 90 days after surgical wound creation. Our results demonstrated that G4 significantly reduced the wound scar depth and density, compared to G1~3. Numbers of cells expressing GFP significantly increased in G4, compared to G2. The protein expression of TGF beta3 and type III collagen in G4 significantly increased, while the ratio of type I to type III collagen was also significantly reduced, which is similar to the tissue architecture found in G5, as compared the other treatment groups. In conclusion, transplantation of BMSCsTGF-beta3 remarkably improves wound healing and reduces skin scar tissue formation in an animal model, which may potentially provide an alternative in the treatment of extensive scar tissue formation after soft tissue injury. PMID- 29453975 TI - miR144-3p inhibits PMVECs excessive proliferation in angiogenesis of hepatopulmonary syndrome via Tie2. AB - BACKGROUND/AIM: Increasing evidence show microRNAs (miRNAs) are associated with hepatopulmonary syndrome (HPS). The aim of this study was to investigate the role of miR-144 in the angiogenesis of HPS, as well as to identify its underlying mechanism. METHODS: The expression levels of miR-144-3p were assessed in pulmonary micro-vascular endothelial cells (PMVECs), as well as in lung tissues from rats with HPS. We predicted the potential target of miR-144-3p. Tyrosine kinase 2(Tie2) was identified as a target gene of miR144-3p, which has an essential role in the angiogenesis of lung vessel. In addition, the effects of miR-144-3p regulated on Tie2 was examined. The upregulation and down-regulation of miR-144-3p can affect the proliferation of PMVECs. RESULTS: We found that the levels of miR-144-3p were frequently downregulated in HPS tissues and cell lines, and overexpression of miR-144-3p dramatically inhibited PMVECs proliferation and cell cycle. We further verified the Tie2 as a novel and direct target of miR-144 3p in HPS. CONCLUSION: miR-144-3p can negatively regulate PMVECs proliferation by Tie2 expression. In addition, overexpression of miR-144-3p may prove beneficial as a therapeutic strategy for HPS treatment. PMID- 29453977 TI - Amelioration of progressive autoimmune encephalomyelitis by epigenetic regulation involves selective repression of mature neutrophils during the preclinical phase. AB - We have recently demonstrated that treatment of NOD mice with the epigenetic drug Trichostatin A (TSA) ameliorated myelin peptide induced progressive experimental autoimmune encephalomyelitis (P-EAE). Protection was accompanied by induction of antigen-specific T-cell tolerance in the periphery and reduced influx of T cells into the spinal cord. In this investigation, we examined whether the epigenetic drug could impact the innate immune system as well. Whereas the mature (MHC class II+) CD11b+Ly-6G+ neutrophils expanded substantially in the peripheral lymphoid compartment during the preclinical phase, the MHC class II+, CD11b+Ly-6C+ mature monocytes increased modestly throughout the disease course. Amelioration of the clinical disease by TSA treatment was accompanied by diminished abundance of CD11b+Ly-6Gdim activated neutrophils in secondary lymphoid organs and their influx into the spinal cord without affecting monocytes. Interestingly, the co inhibitory ligand CD274+ (PD-L1+) but not CD275+ (ICOS-L+), CD39+ or CD11c+ dendritic cells were decreased in the peripheral lymphoid compartment of drug treated mice. Thus, in addition to myelin-specific T cell tolerance induction observed previously, selective repression of mature neutrophils and PD-L1+ cells is critically involved in the epigenetic regulation of P-EAE. PMID- 29453976 TI - Cell-type specific expression of constitutively-active Rheb promotes regeneration of bulbospinal respiratory axons following cervical SCI. AB - Damage to respiratory neural circuitry and consequent loss of diaphragm function is a major cause of morbidity and mortality in individuals suffering from traumatic cervical spinal cord injury (SCI). Repair of CNS axons after SCI remains a therapeutic challenge, despite current efforts. SCI disrupts inspiratory signals originating in the rostral ventral respiratory group (rVRG) of the medulla from their phrenic motor neuron (PhMN) targets, resulting in loss of diaphragm function. Using a rat model of cervical hemisection SCI, we aimed to restore rVRG-PhMN-diaphragm circuitry by stimulating regeneration of injured rVRG axons via targeted induction of Rheb (ras homolog enriched in brain), a signaling molecule that regulates neuronal-intrinsic axon growth potential. Following C2 hemisection, we performed intra-rVRG injection of an adeno-associated virus serotype-2 (AAV2) vector that drives expression of a constitutively-active form of Rheb (cRheb). rVRG neuron-specific cRheb expression robustly increased mTOR pathway activity within the transduced rVRG neuron population ipsilateral to the hemisection, as assessed by levels of phosphorylated ribosomal S6 kinase. By co injecting our novel AAV2-mCherry/WGA anterograde/trans-synaptic axonal tracer into rVRG, we found that cRheb expression promoted regeneration of injured rVRG axons into the lesion site, while we observed no rVRG axon regrowth with AAV2-GFP control. AAV2-cRheb also significantly reduced rVRG axonal dieback within the intact spinal cord rostral to the lesion. However, cRheb expression did not promote any recovery of ipsilateral hemi-diaphragm function, as assessed by inspiratory electromyography (EMG) burst amplitudes. This lack of functional recovery was likely because regrowing rVRG fibers did not extend back into the caudal spinal cord to synaptically reinnervate PhMNs that we retrogradely-labeled with cholera toxin B from the ipsilateral hemi-diaphragm. Our findings demonstrate that enhancing neuronal-intrinsic axon growth capacity can promote regeneration of injured bulbospinal respiratory axons after SCI, but this strategy may need to be combined with other manipulations to achieve reconnection of damaged neural circuitry and ultimately recovery of diaphragm function. PMID- 29453978 TI - Venlafaxine prevents morphine antinociceptive tolerance: The role of neuroinflammation and the l-arginine-nitric oxide pathway. AB - Opioid-induced neuroinflammation and the nitric oxide (NO) signal-transduction pathway are involved in the development of opioid analgesic tolerance. The antidepressant venlafaxine (VLF) modulates NO in nervous tissues, and so we investigated its effect on induced tolerance to morphine, neuroinflammation, and oxidative stress in mice. Tolerance to the analgesic effects of morphine were induced by injecting mice with morphine (50 mg/kg) once a day for three consecutive days; the effect of co-administration of VLF (5 or 40 mg/kg) with morphine was similarly tested in a separate group. To determine if the NO precursor l-arginine hydrochloride (l-arg) or NO are involved in the effects rendered by VLF, animals were pre-treated with l-arg (200 mg/kg), or the NO synthesis inhibitors N(omega)-nitro-l-arginine methyl ester (L-NAME; 30 mg/kg) or aminoguanidine hydrochloride (AG; 100 mg/kg), along with VLF (40 mg/kg) for three days before receiving morphine for another three days. Nociception was assessed with a hot-plate test on the fourth day, and the concentration of tumor necrosis factor alpha (TNF-alpha), interleukin-1beta (IL-1beta), interleukin-6 (IL-6), interleukin-10, brain-derived neurotrophic factor, NO, and oxidative stress factors such as total thiol, malondialdehyde content, and glutathione peroxidase (GPx) activity in the brain was also determined. Co-administration of VLF with morphine attenuated morphine-induced analgesic tolerance and prevented the upregulation of proinflammatory cytokines (TNF-alpha, IL-1beta, and IL-6), NO, and malondialdehyde in brains of mice with induced morphine tolerance; chronic VLF administration inhibited this decrease in brain-derived neurotrophic factor, total thiol, and GPx levels. Moreover, repeated administration of l-arg before receipt of VLF antagonized the effects induced by VLF, while L-NAME and AG potentiated these effects. VLF attenuates morphine-induced analgesic tolerance, at least partly because of its anti-inflammatory and antioxidative properties. VLF also appears to suppress the development of morphine-induced analgesic tolerance through an l-arg-NO-mediated mechanism. PMID- 29453979 TI - Toward a Meaningful Definition of Recovery After Hip Fracture: Comparing Two Definitions for Community-Dwelling Older Adults. AB - OBJECTIVES: To examine the course of recovery and resulting health-related quality of life (HRQL) after low-trauma hip fracture using 2 different definitions of recovery. DESIGN: Inception cohort with 8 assessments over 1 year. SETTING: Participants were recruited from a tertiary-care hospital and followed up in the community. PARTICIPANTS: Community-dwelling hip fracture patients (N=47, 75% of all eligible; aged >=65y). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Prefracture functional level was used to identify subgroups of participants with similar trajectories of mobility over time. Recovery in functional mobility was defined in 2 ways: the "traditional" definition (return to prefracture level of functional mobility) and a "targeted recovery" definition (ability to climb 10 steps). Both were measured using the Lower Extremity Functional Scale. HRQL was measured using the RAND 36-Item Short-Form Health Survey. RESULTS: Participants were categorized into 3 subgroups with: low, medium, and high prefracture functional abilities. Agreement between the 2 definitions of recovery (quantified using kappa coefficient) was strong for the medium group (.81; 95% confidence interval, .56-1.00), weak for the high group (.46; 95% confidence interval, 0.0-.99), and minimal for the low group (.12; 95% confidence interval, 0.0-.328). Contrary to the traditional definition, patients who achieved targeted recovery had statistically and clinically better HRQL than the rest of the cohort throughout the study (estimated average difference of 10.8 points on RAND 36-Item Short-Form Health Survey; 95% confidence interval, 6.67 15.07). CONCLUSIONS: The agreement between the 2 definitions of recovery ranged from minimal to strong according to patient group. Using a functional target to define recovery predicted HRQL better. It is vital to consider the definition of recovery carefully for research or clinical practice because it can influence subsequent decisions (eg, endorsing a specific intervention or discharging patients). PMID- 29453980 TI - Virtual Reality for Upper Limb Rehabilitation in Subacute and Chronic Stroke: A Randomized Controlled Trial. AB - OBJECTIVE: To evaluate the effectiveness of reinforced feedback in virtual environment (RFVE) treatment combined with conventional rehabilitation (CR) in comparison with CR alone, and to study whether changes are related to stroke etiology (ie, ischemic, hemorrhagic). DESIGN: Randomized controlled trial. SETTING: Hospital facility for intensive rehabilitation. PARTICIPANTS: Patients (N=136) within 1 year from onset of a single stroke (ischemic: n=78, hemorrhagic: n=58). INTERVENTIONS: The experimental treatment was based on the combination of RFVE with CR, whereas control treatment was based on the same amount of CR. Both treatments lasted 2 hours daily, 5d/wk, for 4 weeks. MAIN OUTCOME MEASURES: Fugl Meyer upper extremity scale (F-M UE) (primary outcome), FIM, National Institutes of Health Stroke Scale (NIHSS), and Edmonton Symptom Assessment Scale (ESAS) (secondary outcomes). Kinematic parameters of requested movements included duration (time), mean linear velocity (speed), and number of submovements (peak) (secondary outcomes). RESULTS: Patients were randomized in 2 groups (RFVE with CR: n=68, CR: n=68) and stratified by stroke etiology (ischemic or hemorrhagic). Both groups improved after treatment, but the experimental group had better results than the control group (Mann-Whitney U test) for F-M UE (P<.001), FIM (P<.001), NIHSS (P<=.014), ESAS (P<=.022), time (P<.001), speed (P<.001), and peak (P<.001). Stroke etiology did not have significant effects on patient outcomes. CONCLUSIONS: The RFVE therapy combined with CR treatment promotes better outcomes for upper limb than the same amount of CR, regardless of stroke etiology. PMID- 29453981 TI - The C2'- and C3'-endo equilibrium for AMP molecules bound in the cystathionine beta-synthase domain. AB - The equilibrium between C2'- and C3'-endo conformations of nucleotides in solution, as well as their polymers DNA and RNA, has been well studied in previous work. However, this equilibrium of nucleotides in their binding state remains unclear. We observed two AMP molecules, in C3'- and C2'-endo conformations respectively, simultaneously bound to a cystathionine-beta-synthase (CBS) domain dimer of the magnesium and cobalt efflux protein CorC in the crystallographic study. The C2'-endo AMP molecule assumes the higher sugar pucker energy and one more hydrogen bond with the protein than the C3'-endo molecule does. The balance between the high sugar pucker energy and the low binding energy suggests an equilibrium or switch between C2'- and C3'-endo conformations of the bound nucleotides. Our work challenge the previous hypothesis that the ribose of the bound nucleotides would be locked in a fixed conformation. PMID- 29453982 TI - Glucagon-like peptide-1 contributes to increases ABCA1 expression by downregulating miR-758 to regulate cholesterol homeostasis. AB - Abnormal regulation of lipid metabolism is associated with type 2 diabetes mellitus (T2DM). GLP-1 as a new treatment for T2DM, has unique effects in modulating cholesterol homeostasis. However, the mechanism of this effect is largely missing. The aim of this study was to determine the effects of GLP-1 on cholesterol-induced lipotoxicity in hepatocytes and examine the underlying mechanisms. The cell viability was determined, and caspase-3 was used to detect the effects of GLP-1 on cholesterol-induced apoptosis. The alterations of miR-758 and ATP-binding cassette transporter A1 (ABCA1) resulting from cholesterol incubation or GLP-1 were detected by qRT-PCR and Western blot assays. Overexpression of miR-758 abrogated the GLP-1-mediated ABCA1 expression, and conversely, down-regulation of miR-758 aggravated GLP-1's action and revealed significant promotion effects. BODIPY-Cholesterol efflux assay revealed that treatment with miR-758 inhibitor significantly enhanced ABCA1-dependent cholesterol efflux, resulting in reduced total cholesterol. Furthermore, Oil red O staining and cholesterol measurement were used to detect lipid accumulation. As a result, cholesterol significantly attenuated cell viability, promoted cell apoptosis, and facilitated lipid accumulation, and these effects were reversed by GLP-1. This study provides evidence that, in HepG2 cells, GLP-1 may affect cholesterol homeostasis by regulating the expression of miR-758 and ABCA1. These data can inform the development of biomarkers for miR-758, and potentially other drugs, on the key pathways of lipid metabolism. PMID- 29453983 TI - Aldolase A overexpression is associated with poor prognosis and promotes tumor progression by the epithelial-mesenchymal transition in colon cancer. AB - There is increasing evidence that glycolysis is involved in cancer progression. Aldolase is a glycolytic enzyme that catalyzes the reversible conversion of fructose-1,6-bisphosphate to glyceraldehyde-3-phosphate and dihydroxyacetone phosphate. Disruption of the aldolase genes also plays a role in the progression of multiple types of cancer. However, the underlying mechanism of the action of aldolases in colon cancer progression remains elusive. In this study, aldolase A expression was investigated and found to be upregulated along with human colon cancer progression and metastasis at both the mRNA and protein levels in human colon cancer tissues. In addition, silencing aldolase A suppressed colon cancer cell proliferation and invasion and inhibited the EMT phenotype. Aldolase A protein expression in colon cancer was related to tumor location, tumor clinical stage and survival. Kaplan-Meier analysis showed that high aldolase A protein expression was associated with an unfavorable outcome. Moreover, aldolase A affected the development of colon cancer not only by affecting the glucose metabolism but also by interacting with the HIF-1 and other EMT-related signaling pathways; silencing aldolase A resulted in the reduced activity of these signaling pathways. These results indicate that aldolase A has additional non glycolytic functions in transcriptional EMT regulation and may therefore have potential as a therapeutic target or a biomarker for identifying patients at risk for poorer survival. PMID- 29453984 TI - GATA3 acetylation at K119 by CBP inhibits cell migration and invasion in lung adenocarcinoma. AB - GATA3 is a transcriptional factor involved in the development of multiple organs. Post translational modifications of GATA3 are critical to its function. Here, we report that GATA3 interacts with and is acetylated by the acetyltransferase CBP. Class I deacetylases HDAC1, HDAC2 and HDAC3 deacetylate GATA3. The major acetylated site of GATA3 in lung adenocarcinoma cells was determined at lysine 119 (AcK119). Functionally, GATA3-acetylation mimics K119Q mutant was found to inhibit lung adenocarcinoma cell migration and invasion with concomitant downregulation of EMT-controlling transcriptional factors Slug, Zeb1 and Zeb2. Taken together, we demonstrated that GATA3 acetylation at lysine 119 by CBP hinders the migration and invasion of lung adenocarcinoma cells. PMID- 29453985 TI - Zika virus infected primary microglia impairs NPCs proliferation and differentiation. AB - Zika virus (ZIKV) can lead to severe birth defects especially microcephaly in newborns by infecting human neural progenitors and impairing brain development. However, as the resident immune cells in the brain, the role of microglia in the ZIKV pathology is not clearly defined. To understand the interplay between immune response and neural cells, we investigate the interaction between microglia and NPCs during ZIKV infection. Our results demonstrate that primary microglia infected with ZIKV induces an inflammatory response similar to that in human, producing high level of tumor necrosis factor alpha (TNF-alpha), interleukin 6 (IL-6), interleukin 1beta (IL-1beta) and inducible nitric oxide synthase (iNOS). Furthermore, conditional medium (CM) of ZIKV infected microglia showed inhibitory effects on cell proliferation and neuronal differentiation of neural precursor cells (NPCs) derived from E14 mice brain. Blocking cytokines in the CM remarkably improved neurogenesis and decreased astrocytic differentiation of NPCs. Together, our results suggest that microglia mediated neuroinflammation plays an important role in neuropathogenesis during ZIKV infection. PMID- 29453986 TI - Sterol O-acyltransferase 1 deficiency improves defective insulin signaling in the brains of mice fed a high-fat diet. AB - Insulin resistance induced by a high-fat diet (HFD) is related to metabolic diseases, and sterol O-acyltransferase 1 (SOAT1) is a key enzyme for the biosynthesis of cholesteryl ester. In the present study, wild-type (WT) mice and SOAT1-knockout (KO) mice with a C57BL6 background fed a HFD were used to explore the role of SOAT1 in the hypothalamus. The results show that the WT mice exhibited a significant increase in body weight as well as hepatic histologic changes; they also had a lower glucose and insulin tolerance than the WT mice fed a normal diet. However, the metabolic syndrome was attenuated in the SOAT1-KO HFD fed mice. With regard to brain function, the SOAT1-KO HFD-fed mice showed improved cognitive function; they also manifested reduced levels of pro inflammatory cytokines, including tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta), and IL-6, which would otherwise be raised by a HFD. In addition, the HFD led to the overexpression of GFAP and phosphorylated NF kappaB in the hypothalamus, changes that were reversed in the SOAT1-KO HFD-fed mice. Moreover, SOAT1-KO mice improved HFD-caused defective hypothalamic insulin resistance, as evidenced by the upregulation of p-insulin receptor (INSR), p-AKT and p-glycogen synthase kinase (GSK)-3beta, while the downregulation of p-AMP activated protein kinase (AMPK)-alpha and p-acetyl-CoA carboxylase (ACC)-alpha. In addition, similar results were observed in high fructose (HFR)-stimulated astrocytes (ASTs) isolated from WT or KO mice. These results suggest that SOAT1 plays an important role in hypothalamic insulin sensitivity, linked to cognitive impairment, in HFD-fed mice. PMID- 29453987 TI - The role of Foxq1 in proliferation of human dental pulp stem cell. AB - This study aimed to investigate the role for Foxq1 in proliferation activity regulation of dental pulp stem cells (DPSCs). Proliferation of DPSC was induced by calcium hydroxide, then expression alteration of Foxq1 was evaluated. Lentivirus was employed to manipulate Foxq1 level in DPSC, and proliferation activities were evaluated. To look into mechanism regulating Foxq1 level after calcium hydroxide stimulation, expressions of various microRNAs were evaluated, then bioinformatics study and dual-luciferase study were carried out to confirm targeting relationship between microRNA and Foxq1. The result of our study indicated that proliferation activities of DPSCs were enhanced after calcium hydroxide stimulation, during which expression of Foxq1 was also up-regulated. Cell viability and progression from G1 to S phase were both improved with overexpression of Foxq1, and microRNAs profiling study and dual-luciferase result suggested miR-320b contributed to the up-regulation of Foxq1 after calcium hydroxide stimulation. These results suggested that miR-320b mediated Foxq1 up regulation promote proliferation of dental pulp stem cells. PMID- 29453988 TI - Silencing calreticulin gene might protect cardiomyocytes from angiotensin II induced apoptosis. AB - AIMS: Calreticulin (CRT), as a chaperone, contributes to protein folding and quality control cycle. CRT is an important factor regulating Ca2+ that participates in cell apoptosis. However, the function of CRT in the heart is still controversial. Therefore, we aimed to investigate the potential role of CRT in angiotensin II-induced cardiomyocytes apoptosis. MAIN METHODS: Primary cultured neonatal cardiomyocytes were stimulated with angiotensin II to induce the apoptosis. Expression of CRT and endoplasmic reticulum (ER) stress associated protein was detected by western blotting after angiotensin II stimulation for 24 h. The reactive oxygen species (ROS) production and mitochondrial membrane potential (MMP) were also detected. Additionally, the function of CRT on cardiomyocytes apoptosis and ER stress/unfolded protein response signaling pathway was investigated by transfecting specific CRT-targeting siRNA. KEY FINDINGS: Cardiomyocytes apoptosis was induced by angiotensin II. The protein level of CRT was elevated after angiotensin -II stimulation for 24 h. Additionally, the protein levels of GRP78, ATF4, C-ATF6, CHOP and the ROS production were elevated, but the Bcl-2 expression and the level of MMP were down regulated. After silencing CRT gene in the process of angiotensin II-induced cardiomyocytes apoptosis, cardiomyocytes apoptosis rate decreased, meanwhile the protein expression of CRT, GRP78, ATF4, C-ATF6 and CHOP were down-regulated. However, the Bcl-2 expression was up-regulated, and the increase of ROS and the loss of MMP were alleviated. SIGNIFICANCE: Our study demonstrated that CRT might protect cardiomyocytes from apoptosis induced by angiotensin II, in which ER stress and mitochondria function were identified as possible underlying molecular bases. PMID- 29453989 TI - Management of bacterial postoperative endophthalmitis and the role of vitrectomy. AB - Management of postoperative bacterial endophthalmitis was explored in the Endophthalmitis Vitrectomy Study37 in 1995, which has underpinned the core protocols in treatment ever since. While surgical techniques have continued to evolve, little has changed in the overall clinical management as no further large randomized controlled trials have taken place. We review the literature addressing the incidence of endophthalmitis, pathogens, antibiotic therapies, and the role of vitrectomy. We suggest an update to management protocols based on available evidence. While vitreous culture remains the gold standard for diagnosis, new techniques allow bacterial identification after antibiotic administration, so injection should be initiated immediately. Current antibiotic regimes are comprehensive and do not need changing. Intravitreal antibiotics should not be repeated at 48 hours after initial treatment. Vitrectomy should be considered instead if the clinical picture is not improving. PMID- 29453990 TI - ATP-activated P2X7 receptor in the pathophysiology of mood disorders and as an emerging target for the development of novel antidepressant therapeutics. AB - Mood disorders are a group of psychiatric conditions that represent leading global disease burdens. Increasing evidence from clinical and preclinical studies supports that innate immune system dysfunction plays an important part in the pathophysiology of mood disorders. P2X7 receptor, belonging to the ligand-gated ion channel P2X subfamily of purinergic P2 receptors for extracellular ATP, is highly expressed in immune cells including microglia in the central nervous system (CNS) and has a vital role in mediating innate immune response. The P2X7 receptor is also important in neuron-glia signalling in the CNS. The gene encoding human P2X7 receptor is located in a locus of susceptibility to mood disorders. In this review, we will discuss the recent progress in understanding the role of the P2X7 receptor in the pathogenesis and development of mood disorders and in discovering CNS-penetrable P2X7 antagonists for potential uses in in vivo imaging to monitor brain inflammation and antidepressant therapeutics. PMID- 29453991 TI - Identification of branched-chain amino acid aminotransferases active towards (R) (+)-1-phenylethylamine among PLP fold type IV transaminases. AB - New class IV transaminases with activity towards L-Leu, which is typical of branched-chain amino acid aminotransferases (BCAT), and with activity towards (R) (+)-1-phenylethylamine ((R)-PEA), which is typical of (R)-selective (R) amine:pyruvate transaminases, were identified by bioinformatics analysis, obtained in recombinant form, and analyzed. The values of catalytic activities in the reaction with L-Leu and (R)-PEA are comparable to those measured for characteristic transaminases with the corresponding specificity. Earlier, (R) selective class IV transaminases were found to be active, apart from (R)-PEA, only with some other (R)-primary amines and D-amino acids. Sequences encoding new transaminases with mixed type of activity were found by searching for changes in the conserved motifs of sequences of BCAT by different bioinformatics tools. PMID- 29453992 TI - Serum cystatin C level is associated with carotid arterial wall elasticity in subjects with type 2 diabetes mellitus: A potential marker of early-stage atherosclerosis. AB - AIMS: Detection of early-stage atherosclerosis in type 2 diabetes mellitus (T2DM) patients is important for preventing cardiovascular disease. A phased tracking method for evaluating arterial wall elasticity sensitively detects early-stage atherosclerosis. However, biochemical markers for early-stage atherosclerosis have yet to be established. METHODS: This cross-sectional study enrolled 180 T2DM patients, who were classified as not having atherosclerosis according to the carotid intima-media thickness (IMT) criteria. We measured serum cystatin C, the estimated glomerular filtration rate (eGFR) and urinary albumin-to-creatinine ratio (ACR), and analyzed the associations between these markers and arterial wall elasticity (Etheta), IMT and the cardio-ankle velocity index. RESULTS: Multiple linear regression analyses revealed that cystatin C was significantly associated with Etheta, while neither eGFR nor ACR showed an association. Furthermore, among the examined atherosclerotic markers, Etheta was most reliably associated with cystatin C. Additionally, the association between cystatin C and Etheta disappeared in the low elasticity subgroup, which included subjects in whom no atherosclerotic changes had yet been initiated. CONCLUSIONS: In T2DM patients without apparent arterial wall thickening, cystatin C is strongly and independently associated with arterial wall elasticity, which reflects the degree of subclinical atherosclerosis. Thus, cystatin C is a potentially useful marker of early-stage atherosclerosis. PMID- 29453993 TI - The tegumental allergen-like proteins of Schistosoma mansoni: A biochemical study of SmTAL4-TAL13. AB - Schistosoma mansoni, like other trematodes, expresses a number of unusual calcium binding proteins which consist of an EF-hand domain joined to a dynein light chain-like (DLC-like) domain by a flexible linker. These proteins have been implicated in host immune responses and drug binding. Three members of this protein family from S. mansoni (SmTAL1, SmTAL2 and SmTAL3) have been well characterised biochemically. Here we characterise the remaining family members from this species (SmTAL4-13). All of these proteins form homodimers and all except SmTAL5 bind to calcium and manganese ions. SmTAL9, 10 and 11 also bind to magnesium ions. The antischistosomal drug, praziquantel interacts with SmTAL4, 5 and 8. Some family members also bind to calmodulin antagonists such as chlorpromazine and trifluoperazine. Molecular modelling suggests that all ten proteins adopt similar overall folds with the EF-hand and DLC-like domains folding discretely. Bioinformatics analyses suggest that the proteins may fall into two main categories: (i) those which bind calcium ions reversibly at the second EF-hand and may play a role in signalling (SmTAL1, 2, 8 and 12) and (ii) those which bind calcium ions at the first EF-hand and may play either signalling or structural roles (SmTAL7, 9, 10 and 13). The remaining proteins include those which do not bind calcium ions (SmTAL3 and 5) and three other proteins (SmTAL4, 6 and 11). The roles of these proteins are less clear, but they may also have structural roles. PMID- 29453994 TI - Land use change and conversion effects on ground water quality trends: An integration of land change modeler in GIS and a new Ground Water Quality Index developed by fuzzy multi-criteria group decision-making models. AB - This study aggregated Land Change Modeller (LCM) as a useful model in GIS with an extended Groundwater Quality Index (GWQI) developed by fuzzy Multi-Criteria Group Decision-Making models to investigate the effect of land use change and conversion on groundwater quality being supplied for drinking. The model's performance was examined through an applied study in Shiraz, Iran, in a five year period (2011 to 2015). Four land use maps including urban, industrial, garden, and bare were employed in LCM model and the impact of change in area and their conversion to each other on GWQI changes was analysed. The correlation analysis indicated that increase in the urban land use area and conversion of bare to the residential/industrial land uses, had a relation with water quality decrease. Integration of LCM and GWQI can accurately and logically provide a numerical analysis of the possible impact of land use change and conversion, as one of the influencing factors, on the groundwater quality. Hence, the methodology could be used in urban development planning and management in macro level. PMID- 29453995 TI - Changes of lipid peroxidation and glutathione redox system, and expression of glutathione peroxidase regulatory genes as effect of short-term aflatoxin B1 exposure in common carp. AB - Lipid peroxidation, glutathione content, glutathione peroxidase activity and gene expression of transcription factors, glutathione peroxidase, glutathione synthetase and glutathione reductase was investigated in common carp liver. Short term (24 h) exposure of aflatoxin B1 at different doses (100, 200 and 400 MUg AFB1 kg-1 feed) was used. It was found that conjugated dienes and trienes elevated after 16 h, while thiobarbituric acid reactive substances content increased only at the lowest dose after 16 and 24 h of exposure. Glutathione content showed higher levels than control after 16 h of exposure and glutathione peroxidase (GPx4) activity was higher in all of the AFB1 treated than the control group after 8 h of exposure. Gene expression of transcription factors showed dual response. Expression of keap1 gene down-regulated after 8 h and 16 h and nrf2 gene after16 h, but up-regulated after 24 h of exposure in the lowest, and highest dose groups. Expression of gpx4a and gpx4b genes down-regulated after 8 h and induction was found after 16 and 24 h of exposure, irrespective of the dose. The results indicated that low dose of AFB1 provokes oxidative stress earlier than higher doses, which activated the Keap1-Nrf2 pathway. At higher doses this pathway activated later, but preformed GPx4 effectively prevented lipid peroxidation. PMID- 29453996 TI - Systematic review of botulinum toxin treatment for oromandibular dystonia. AB - Oromandibular dystonia (OMD) is an isolated focal dystonia that affects the muscles of the jaw, lower face and tongue. It is a rare disorder but is associated with significant impairment in quality of life. Treatment with oral medications has not been successful. Surgical interventions, such as deep brain stimulation, may be of benefit but have not been adequately evaluated. Currently, botulinum toxin (BoNT) injections are regarded as the treatment of choice for OMD. However, the evidence supporting this is not available. Most studies are open label, observational studies, longitudinal clinical experience, case reports or retrospective analysis. From the available studies, OMD is responsive to appropriately targeted BoNT injections. Jaw closing dystonia responds the most robustly. Jaw opening dystonia is more complex to inject, but clinical experience is consistent with benefit. Lingual dystonia is the most difficult because injections into tongue muscles frequently give rise to dysphagia. More controlled studies are required to establish BoNT as an effective treatment for OMD. PMID- 29453997 TI - Effects of para-methoxyamphetamine (PMA) on agonistic encounters between male mice. AB - Para-methoxyamphetamine (PMA) is a synthetic drug chemically similar to the recreational drug 3,4-methylenedioxy-methamphetamine (MDMA or "ecstasy") and often replaces MDMA in tablets that show an "ecstasy" logo. PMA displays a higher toxic potential than MDMA, but the behavioral profile of PMA has been scarcely studied in animal models. Here we evaluated the effects of PMA (2, 4, 8, and 12 mg/kg, i.p.) on agonist encounters between male mice using an ethopharmacological approach, the isolation-induced aggression model. Likewise, since PMA and MDMA share common mechanisms of action, we compared the behavioral profile of PMA with that induced by MDMA (8 mg/kg, i.p.) which behavioral effects in this model are well characterized. Individually housed mice were exposed to anosmic standard opponents 30 min after drug administration. The encounters were videotaped and evaluated using an ethologically based analysis. PMA (all doses) significantly reduced offensive behaviors (threat and attack), however, a detailed behavioral analysis suggests that the observed antiaggressive effect seems to be unspecific, showing a complex dose-dependent behavioral profile. Thus, antiaggresive actions observed after the administration of the lowest dose were accompanied by increases in social investigation, avoidance/flee behaviors and non-social explorations, together with a reduction of digging behavior. This pattern reflects both approach-contact behaviors and avoidance-flee behaviors. From 4 mg/kg to 12 mg/kg, the increase in social investigation previously observed disappears, and there is a slight increase in immobility, together with a different behavioral pattern that suggests anxiogenic effects of PMA, similar to those reported after the administration of MDMA. The higher doses of PMA exhibit a behavioral profile very similar to that observed in animals treated with MDMA, with the exception of the immobility produced by PMA. These findings show for the first time the non-specific antiaggressive profile of PMA in the model of aggression induced by isolation in male mice. PMID- 29453998 TI - CTL14, a recognition receptor induced in late stage larvae, modulates anti-fungal immunity in cotton bollworm Helicoverpa armigera. AB - C-type lectin (CTL) is usually considered as pattern recognition receptors in insect innate immunity. Here we found that CTL14 of Helicoverpa armigera was only activated in the fifth instar larvae not in the second instar by entomopathogen Beauveria bassiana infection. Recombinant CTL14 protein was found to form aggregates with zymosan and B. bassiana in vitro. Immunoprecipitation studies demonstrated that CTL14 interacted with serine proteinases (SP), serine proteinase inhibitor (serpin), prophenoloxidases (PPO) and vitellogenin (Vg) in the larval hemolymph. Furthermore, depletion of CTL14 using dsRNA led to dramatic decrease in the expression level of PPO1. Additionally, CTL14 depleted H. armigera decreased the resistance to fungal challenge. Taken together, our study showed the direct involvement of CTL14 in the anti-fungal immunity of H. armigera, which further explained the stronger immune responses in the fifth instar compared to the second instar larvae. PMID- 29453999 TI - Evolutionary and expression analyses reveal a pattern of ancient duplications and functional specializations in the diversification of the Downstream of Kinase (DOK) genes. AB - Downstream of Kinase (DOK) proteins represent a multigenic family of adaptors that includes negative regulators of immune cell signaling. Using phylogenetics and intron/exon structure data, we show here that the seven human DOK genes (DOK1 to DOK7) form three highly divergent groups that emerged before the protostome deuterostome split: DOK1/2/3, DOK4/5/6, and DOK7. For two of these three groups (DOK1/2/3 and DOK4/5/6), further gene duplications occurred in vertebrates and so while chordates only have three DOK genes, vertebrates have seven DOK genes over the three groups. From our expression analysis in humans, we show that each group of DOK genes has a distinct pattern of expression. The DOK1/2/3 group is immune specific, yet each of the three genes in the group has a distinct pattern of expression in immune cells. This immune specificity could thus be ancestral, with the DOK1/2/3 gene also being immune-related in protostomes. The DOK4/5/6 and DOK7 groups represent genes that are much less expressed in immune system than the DOK1/2/3 group. Interestingly, we identify a novel tyrosine based motif that is specific to the vertebrate DOK4/5/6 sequences.

The deficiency results in increased levels of Phe and its metabolites in fluids and tissues of patients. PKU patients present neurological signs and symptoms including hypomyelination and intellectual deficit. This study assessed brain bioenergetics at 1 h after acute Phe administration to induce hyperphenylalaninemia (HPA) in rats. Wistar rats were randomized in two groups: HPA animals received a single subcutaneous administration of Phe (5.2 MUmol/g) plus p-Cl-Phe (PAH inhibitor) (0.9 MUmol/g); control animals received a single injection of 0.9% NaCl. In cerebral cortex, HPA group showed lower mitochondrial mass, lower glycogen levels, as well as lower activities of complexes I-III and IV, ATP synthase and citrate synthase. Higher levels of free Pi and phospho-AMPK, and higher activities of LDH, alpha ketoglutarate dehydrogenase and isocitrate dehydrogenase were also reported in cerebral cortex of HPA animals. In striatum, HPA animals had higher LDH (pyruvate to lactate) and isocitrate dehydrogenase activities, and lower activities of alpha-ketoglutarate dehydrogenase and complex IV, as well as lower phospho-AMPK immunocontent. In hippocampus, HPA rats had higher mRNA expression for MFN1 and higher activities of alpha-ketoglutarate dehydrogenase and isocitrate dehydrogenase, but decreased activities of pyruvate dehydrogenase and complexes I and IV. In conclusion, our data demonstrated impaired bioenergetics in cerebral cortex, striatum and hippocampus of HPA rats. PMID- 29454002 TI - Biodiversity: The new kid on the block? PMID- 29454000 TI - Anticipatory stress associated with functional magnetic resonance imaging: Implications for psychosocial stress research. AB - Stress tasks performed during functional magnetic resonance imaging (fMRI) elicit a relatively small cortisol response compared to stress tasks completed in a traditional behavioral laboratory, which may be due to apprehension of fMRI that elicits an anticipatory stress response. The present study investigated whether anticipatory stress is greater prior to research completed in an MRI environment than in a traditional behavioral laboratory. Anticipatory stress (indexed by cortisol) was greater prior to testing in the MRI environment than traditional behavioral laboratory. Furthermore, anticipation of fMRI elicited a cortisol response commensurate with the response to the stress task in the behavioral laboratory. However, in the MRI environment, post-stress cortisol was significantly lower than baseline cortisol. Taken together, these findings suggest the stress elicited by anticipation of fMRI may lead to acute elevations in cortisol prior to scanning, which may in turn disrupt the cortisol response to stress tasks performed during scanning.

PMID- 29454005 TI - A quest to find good primers for gene expression analysis of Candida albicans from clinical samples. AB - Biofilm production contributes to several human diseases, including oral candidiasis. Among the Candida species, Candida albicans is the most prevalent. The expression of virulence genes is implicated in the pathogenic potential of Candida biofilms. However, the evaluation of microbial gene expression from in vivo biofilm samples is not trivial, specifically, assessment via quantitative PCR (qPCR) can be a challenge because of several species present in clinical samples. Hence, the necessity of primers specificity. The aim of this study was to evaluate through in silico and in vitro analyses the specificity of published primers and newly designed primers for C. albicans virulence genes: ALS1, CAP1, CAT1, EFG1, HWP1, LIP3, PLB1, SAP1, SAP4, SOD1, SOD5 and ACT1 (normalizing gene). In silico analysis was performed through a PubMed search of articles with primer sequences that evaluated gene expression of C. albicans. Then, the sequence similarity of twenty-eight primers was checked through BLASTn and ClustalW2. The analysis of secondary structures was performed using mfold. When the primers did not present satisfactory characteristics (absence of secondary structures, not discrepant Tm of forward and reverse sequences and specificity) following in vitro analysis (i.e., end point PCR), new primers were designed using Beacon DesignerTM and sequences obtained from the "Candida Genome Database". The selected primers were tested in vitro by end point PCR using a panel of genomic DNA from five different Candida species (C. albicans, Candida glabrata, Candida dubliniensis, Candida krusei, and Candida tropicalis). The resulting PCR products were visualized on agarose gel. qPCR reactions were performed to determine primers' optimal concentration and PCR efficiency. End point PCR demonstrated that published primers for the SAP1 and HWP1 were specific for C. albicans and the one for SOD1 reacted with C. albicans and C. dubliniensis. The sequence of primers designed for ACT1, ALS1 and HWP1 genes were specific for C. albicans, while the ones for CAP1, CAT1, EFG1, LIP3, and PLB1 were detected in C. albicans and C. dubliniensis. After optimization, all primers presented a single peak on melt curves, correlation coefficient of ?1 and qPCR reaction efficiency of 90 110%, with slope of ?-3.3. Therefore, these primers should be suitable for future gene expression analyses from clinical samples. PMID- 29454004 TI - Identification and analysis of peanut-specific effector T and regulatory T cells in children allergic and tolerant to peanut. AB - BACKGROUND: Peanut allergy (PA) is potentially life-threatening and generally persists for life. Recent data suggest the skin might be an important route of initial sensitization to peanut, whereas early oral exposure to peanut is protective. In mice regulatory T (Treg) cells are central to the development of food tolerance, but their contribution to the pathogenesis of food allergy in human subjects is less clear. OBJECTIVE: We sought to quantify and phenotype CD4+ peanut-specific effector T (ps-Teff) cells and peanut-specific regulatory T (ps Treg) cells in children with and without PA or PS. METHODS: ps-Teff and ps-Treg cells were identified from peripheral blood of children with PA, children with PS, and nonsensitized/nonallergic (NA) school-aged children and 1-year-old infants based on upregulation of CD154 or CD137, respectively, after stimulation with peanut extract. Expression of cytokines and homing receptors was evaluated by using flow cytometry. Methylation at the forkhead box protein 3 (FOXP3) locus was measured as a marker of Treg cell stability. RESULTS: Differential upregulation of CD154 and CD137 efficiently distinguished ps-Teff and ps-Treg cells. A greater percentage of ps-Teff cells from infants with PA and infants with PS expressed the skin-homing molecule cutaneous lymphocyte antigen, suggesting activation after exposure through the skin, compared with NA infants. Although ps-Teff cells in both school-aged and infant children with PA produced primarily TH2 cytokines, a TH1-skewed antipeanut response was seen only in NA school-aged children. The frequency, homing receptor expression, and stability of ps-Treg cells in infants and school-aged children were similar, regardless of allergic status. CONCLUSIONS: Exposure to peanut through the skin can prime the development of TH2 ps-Teff cells, which promote sensitization to peanut, despite the presence of normal numbers of ps-Treg cells. PMID- 29454006 TI - Predicting cognitive decline with deep learning of brain metabolism and amyloid imaging. AB - For effective treatment of Alzheimer's disease (AD), it is important to identify subjects who are most likely to exhibit rapid cognitive decline. We aimed to develop an automatic image interpretation system based on a deep convolutional neural network (CNN) which can accurately predict future cognitive decline in mild cognitive impairment (MCI) patients using flurodeoxyglucose and florbetapir positron emission tomography (PET). PET images of 139 patients with AD, 171 patients with MCI and 182 normal subjects obtained from Alzheimer's Disease Neuroimaging Initiative database were used. Deep CNN was trained using 3 dimensional PET volumes of AD and normal controls as inputs. Manually defined image feature extraction such as quantification using predefined region-of interests was unnecessary for our approach. Furthermore, it used minimally processed images without spatial normalization which has been commonly used in conventional quantitative analyses. Cognitive outcome of MCI subjects was predicted using this network. The prediction accuracy of the conversion of mild cognitive impairment to AD was compared with the conventional feature-based quantification approach. Accuracy of prediction (84.2%) for conversion to AD in MCI patients outperformed conventional feature-based quantification approaches. ROC analyses revealed that performance of CNN-based approach was significantly higher than that of the conventional quantification methods (p < 0.05). Output scores of the network were strongly correlated with the longitudinal change in cognitive measurements (p < 0.05). These results show the feasibility of deep learning as a practical tool for developing predictive neuroimaging biomarker. PMID- 29454007 TI - Destruction of noradrenergic terminals increases dopamine concentration and reduces dopamine metabolism in the medial prefrontal cortex. AB - Effects of destroyed noradrenergic (NE) innervation in the medial prefrontal cortex (mPFC) were examined on dopamine (DA) content and metabolism. Six-hydroxy DOPA (6-OHDOPA) or 6-hydroxy-dopamine (6-OHDA) in combination with a potent DA reuptake inhibitor GBR 12935 or 6-OHDA were injected bilaterally into the mPFC in separate groups of animals. In addition, GBR 12935 or vehicle was injected into the mPFC in two other groups of animals as control experiments. NE and DA concentrations from postmortem tissue of the mPFC were measured using HPLC with electrochemical detection. In addition, extracellular NE, DA and DOPAC levels were determined using in vivo microdialysis after the 6-OHDA lesion in combination with GBR 12935 pretreatment in the mPFC. Using reverse microdialysis of alpha-2-adrenoreceptor antagonist yohimbine, we tested the remaining activity of NE innervation and the extracellular concentration of DA and DOPAC. NE and DA concentrations from postmortem tissue of the mPFC showed that 6-OHDOPA lesion reduced NE concentration to 76%, which was a non-significant alteration, however it enhanced significantly DA concentration to 186% compared to vehicle. After 6 OHDA lesion with GBR 12935 pretreatment, concentration of NE significantly decreased to 51% and DA level increased to 180%. 6-OHDA lesion without GBR 12635 pretreatment decreased NE concentration to 23% and DA concentration to 67%. In the microdialysis experiment, after 6-OHDA lesion with GBR 12935 pretreatment, extracellular NE levels were not detectable, whereas extracellular DA levels were increased and DOPAC levels were decreased compared to controls. Reverse microdialysis of yohimbine demonstrated that the residual NE innervation was able to increase NE level and DA levels, but DOPAC concentration remained low after lesion of the NE terminals. These findings suggest that the damage of NE innervation in the mPFC may alter extracellular DA level due to a reduced DA clearance. PMID- 29454008 TI - Temozolomide affects Extracellular Vesicles Released by Glioblastoma Cells. AB - Glioblastoma multiforme (GBM) is the most aggressive primary tumour within the brain as well as the most common and lethal cerebral cancer, mainly because of treatment failure. Indeed, tumour recurrence is inevitable and fatal in a short period of time. Glioblastoma stem-like cells (GSCs) are thought to participate in tumour initiation, expansion, resistance to treatments, including to the alkylating chemotherapeutic agent temozolomide, and relapse. Here, we assessed whether extracellular vesicles (EVs) released by GSCs could disseminate factors involved in resistance mechanisms. We first characterized EVs either circulating in peripheral blood from newly diagnosed patients or released by patient-derived temozolomide-resistant GSCs. We found that EVs from both sources were mainly composed of particles homogeneous in size (50-100 nm), while they were more abundant in liquid biopsies from GBM patients, as compared to healthy donors. Further, mass spectrometry analysis from GSC-derived EVs unveiled that particles from control and temozolomide-treated cells share core components of EVs, as well as ribosome- and proteasome-associated networks. More strikingly, temozolomide treatment led to the enrichment of EVs with cargoes dedicated to cell adhesion processes. Thus, while relatively inefficient in killing GSCs in vitro, temozolomide could instead increase the release of pro-tumoral information. PMID- 29454010 TI - Enhancing creative cognition with a rapid right-parietal neurofeedback procedure. AB - The present article describes an innovative neurofeedback training (NFT) procedure aimed at increasing creative cognition through the enhancement of specific brain activities previously associated with divergent thinking. We designed and tested two NFT protocols based on training alpha and beta EEG oscillations selectively measured over the right parietal region. A total of 80 participants were involved, 40 in the alpha NFT protocol and 40 in the beta NFT protocol. The NFT loop was closed on a video stream that would advance only when oscillation power exceeded a normalized threshold. The total duration of the protocol was two hours in a single day, hence its classification as rapid. Changes in ideational fluency and originality, measured with a divergent thinking task, were compared between participants receiving real video feedback and participants receiving sham feedback. We controlled for individual differences in creative achievement level. Results showed that the protocols were effective at enhancing alpha and beta activities in the targeted area. Differences between the two protocols emerged in their effectiveness at promoting divergent thinking. While no significant changes in originality resulted from the rapid alpha NFT, increases in both originality and fluency emerged as a consequence of the rapid beta NFT. These results were particularly evident in participants starting with a low creative achievement level. Possible interpretations and future directions are proposed and discussed. PMID- 29454011 TI - Comparative study on some oxidative stress parameters in blood of vitiligo patients before and after combined therapy. AB - Currently accepted that oxidative stress is a triggering event in the melanocytic destruction and is probably involved in the etiopathogenesis of vitiligo disease. Despite numerous investigations, contradictory results were reported about the levels of oxidative stress biomarkers measured in the skin and blood of vitiligo patients. By Electron Paramagnetic Resonance spectroscopy (EPR) and spectrophotometry, we have investigated and compared some oxidative stress biomarkers in the blood of vitiligo patients' before and after UVB Narrow Band 311 nm phototherapy combined with the antioxidant nutritional supplement containing - Vitamin C, Vitamin B1, L -Cysteine, Lipoic Acid, and polyunsaturated fatty acids. Before therapy was found significantly higher levels of CAT activity and MDA compared to the patients after therapy and control group (p < 0.05). Moreover, levels of Asc* radicals in patients before therapy were significantly lower than those measured in controls and patients undergoing therapy (p < 0.05). Our finding, the combined therapy applied to vitiligo patients provoked an increase in the Asc* levels and a decrease in MDA products and also initial repigmentation in the vitiligo spots, made us believe that a combined antioxidant therapy, enriched with vitamin C could lead to improvement of the oxidant antioxidant balance in vitiligo patients treated with UVB 311 phototherapy. PMID- 29454009 TI - 24 vs. 72 hours of hypothermia for pediatric cardiac arrest: A pilot, randomized controlled trial. AB - AIM: Children surviving cardiac arrest (CA) lack proven neuroprotective therapies. The role of biomarkers in assessing response to interventions is unknown. We hypothesized that 72 versus 24 h of hypothermia (HT) would produce more favorable biomarker profiles after pediatric CA. METHODS: This single center pilot randomized trial tested HT (33 +/- 1 degrees C) for 24 vs. 72 h in 34 children with CA. Children comatose after return of circulation aged 1 week to 17 years and treated with HT by their physician were eligible. Serum was collected twice daily on days 1-4 and once on day 7. Mortality was assessed at 6 months. RESULTS: Patient characteristics, baseline biomarker concentrations, and adverse events were similar between groups. Eight (47%) and 4 (24%) children died in the 24 h and 72 h groups, p = .3. Serum neuron specific enolase (NSE) concentration was increased in the 24 vs. 72 h group at 84 h-96 h (median [interquartile range] 47.7 [3.9, 79.9] vs. 1.4 [0.0, 11.1] ng/ml, p = .02) and on day 7 (18.2 [3.2, 74.0] vs. 2.6 [0.0, 12.8] ng/ml, p = .047). Serum S100b was increased in the 24 h vs. 72 h group at 12 h-24 h, 36 h-84 h, and on day 7, all p < 0.05. HT duration was associated with S100b (but not NSE or MBP) concentration on day 7 in multivariate analyses. CONCLUSION: Serum biomarkers show promise as theragnostic tools in pediatric CA. Our biomarker and safety data also suggest that 72 h duration after pediatric CA warrants additional exploration.

PMID- 29454012 TI - Immunologic effects of chronic administration of tofacitinib, a Janus kinase inhibitor, in cynomolgus monkeys and rats - Comparison of juvenile and adult responses. AB - Tofacitinib, an oral Janus kinase (JAK) inhibitor for treatment of rheumatoid arthritis, targets JAK1, JAK3, and to a lesser extent JAK2 and TYK2. JAK1/3 inhibition impairs gamma common chain cytokine receptor signaling, important in lymphocyte development, homeostasis and function. Adult and juvenile cynomolgus monkey and rat studies were conducted and the impact of tofacitinib on immune parameters (lymphoid tissues and lymphocyte subsets) and function (T-dependent antibody response (TDAR), mitogen-induced T cell proliferation) assessed. Tofacitinib administration decreased circulating T cells and NK cells in juvenile and adult animals of both species. B cell decreases were observed only in rats. These changes and decreased lymphoid tissue cellularity are consistent with the expected pharmacology of tofacitinib. No differences were observed between juvenile and adult animals, either in terms of doses at which effects were observed or differential effects on immune endpoints. Lymphomas were observed in three adult monkeys. Tofacitinib impaired the primary TDAR in juvenile monkeys, although a recall response was generated. Complete or partial reversal of the effects on the immune system was observed. PMID- 29454014 TI - Detecting structural and inflammatory response after in vivo stretch injury in the rat median nerve via second harmonic generation. AB - BACKGROUND: Second Harmonic Generation (SHG) microscopy is a promising method for visualizing the collagenous structure of peripheral nerves. Assessing collagen continuity and damage after a stretch injury provides inferential insight into the level of axonal damage present. NEW METHODS: This study utilizes SHG microscopy after a calibrated in vivo stretch injury of rat median nerves to evaluate collagen continuity at several time points throughout the recovery process. Endoneurial collagen was qualitatively assessed in nerves that were subjected to low strain (LS) and high strain (HS) injuries using SHG microscopy, conventional histology, and immunohistochemistry. RESULTS: Following an in vivo stretch injury, both LS and HS damaged nerves exhibit signs of structural collagen damage in comparison with sham control nerves (SC). Furthermore, LS nerves exhibit signs of full regeneration while HS nerves exhibited signs of only partial regeneration with lasting damage and intra-neural scar formation. COMPARISON WITH EXISTING METHODS: SHG observations of structural changes and inflammatory response due to stretch injury were validated upon comparison with conventional histological methods CONCLUSIONS: We propose that SHG microscopy can be utilized to visualize significant structural artifacts in sectioned median nerves following in vivo stretch injury. Based on the findings in this study, we believe that the in vivo application of SHG microscopy should be further investigated as a means for real-time, intra-operative, quantitative assessment of nerve damage. PMID- 29454015 TI - Why I eat at night: A qualitative exploration of the development, maintenance and consequences of Night Eating Syndrome. AB - Night Eating Syndrome (NES), as a diagnosis, presents as a combination of disordered eating, sleep and mood. Patients identified as having both NES and obesity demonstrate poorer outcomes in terms of weight loss compared to those with NES only. However, research focusing on psychological factors associated with NES remains relatively underdeveloped. This study aimed to explore the relationship between NES and the experience of emotion from the perspective of patients accessing a weight management service. Ten adults who met diagnostic criteria for moderate or full NES took part in a semi-structured interview. Data were analysed using a constructivist approach to grounded theory. A core concept to emerge from the analysis was termed 'emotional hunger'; reflecting an urge or need to satiate a set of underlying unmet emotional needs. It was underpinned by the following interrelated themes: (1) Cultivating a dependency on food; (2) Relying on food to regulate emotions; (3) Understanding the significance of night time; (4) Acknowledging the consequences of night eating. This study provides an in-depth understanding of the relationship between NES and the experience of emotion from the perspective of patients attending a weight management service. Results have potential to inform future service development, particularly around the adoption of a more holistic approach to night eating behaviours. PMID- 29454016 TI - Mother and child personality traits associated with common feeding strategies and child body mass index. AB - The feeding strategies that parents use with their children shape their children's attitudes and behaviors toward food. The present research examined whether personality traits of the mother and the child are associated with the types of feeding strategies mothers use with their children. The present research also examined whether these characteristics are associated with the child's body mass index (BMI). Mothers (N = 2928) reported how often they used three feeding strategies (Restriction, Pressure to Eat, Monitoring) with the target child and their personality and the personality of the child. Both mother and child Conscientiousness were associated significantly with less use of Restriction and Pressure to Eat and more use of Monitoring. Child Openness and Agreeableness were likewise related to less use of Restriction and Pressure to Eat. Mother and child Conscientiousness were associated with child obesity: Children with obesity scored lower in Conscientiousness and also had mothers who scored lower on this trait; Restriction and Pressure to Eat partially mediated the association between mother Conscientiousness and child BMI. The present findings suggest that individual differences in both mother and child personality are associated with the use of three common feeding strategies in childhood and the child's weight. PMID- 29454017 TI - A rapid method for titration of ascovirus infectivity. AB - Ascoviruses are a recently described family and the traditional plaque assay and end-point PCR assay have been used for their titration. However, these two methods are time-consuming and inaccurate to titrate ascoviruses. In the present study, a quick method for the determination of the titer of ascovirus stocks was developed based on ascovirus-induced apoptosis in infected insect cells. Briefly, cells infected with serial dilutions of virus (10-2-10-10) for 24 h were stained with trypan blue. The stained cells were counted, and the percentage of nonviable cells was calculated. The stained cell rate was compared between virus-infected and control cells. The minimum-dilution group that had a significant difference compared with control and the maximum-dilution group that had no significant difference were selected and then compared each well of the two groups with the average stained cell rate of control. The well was marked as positive well if the stained cell rate was higher than the average stained cell rate of control wells; otherwise, the well was marked as negative wells. The percentage of positive wells were calculated according to the number of positive. Subsequently, the virus titer was calculated through the method of Reed and Muench. This novel method is rapid, simple, reproducible, accurate, and less material-consuming and eliminates the subjectivity of the other procedures for titrating ascoviruses. PMID- 29454018 TI - Co-circulation of classic and novel astrovirus strains in patients with acute gastroenteritis in Germany. AB - OBJECTIVES: In order to analyze the molecular epidemiology of human astroviruses (HAstV) in Germany, a retrospective long-term study was performed to characterize circulating human astrovirus in patients with acute gastroenteritis in Germany. METHODS: A total of 2877 stool samples, collected between January 2010 and December 2015 from sporadic cases and outbreaks of acute gastroenteritis were retrospectively analyzed for astrovirus. A two-step PCR algorithm was developed and used to identify and characterize human astrovirus infections. RESULTS: Overall, 143 samples were astrovirus-positive (5.0%). Astrovirus infection was most frequently detectable in samples from children of 3-4 years (15%) followed by children of 1-2 years (8.6%), detection rates in adults were lower (1%-3.6%). A high number (71.3%) of co-infections, mainly with noro- or rotaviruses, were identified. Genotyping revealed that at least ten genotypes from all four human MAstV species were circulating in the study population. HAstV-1 was predominant in different age groups. Novel HAstV (MLB and VA genotypes) were also circulating in Germany. CONCLUSION: Our findings give new insights into the circulation and genetic diversity of human astroviruses in patients with acute gastroenteritis. The novel HAstV-MLB and -VA genotypes could be characterized firstly in Germany while the analysis showed that these viruses have been dispersed in Germany since 2011 as a causative agent of acute gastroenteritis.

AB - Eighteen alkaloids were detected in the bark, leaves, wood and roots of Peumus boldus, including traces of secoboldine, N-methylsecoboldine (boldine methine), glaucine and norreticuline, not reported previously as constituents of this species. Using appropriate standards, we quantified thirteen of them by UHPLC MS/MS. Boldine was dominant in the bark, and laurolitsine in wood and roots. The alkaloid composition of the leaves, determined for 130 individually identified trees, classified by age and sex, was highly variable, where N methyllaurotetanine, laurotetanine, coclaurine and in some cases isocorydine predominated, but not boldine. PMID- 29454021 TI - Three new quinazolines from Evodia rutaecarpa and their biological activity. AB - In this research, we investigated the profile and bioactivities of quinazoline alkaloids, a class of natural products boasting multiple bioactivities, from the unripe fruit of Evodia rutaecarpa (Juss.) Benth. Three new quinazoline alkaloids, evodiamide A (1), evodiamide B (2), and evodiamide C (3), as well as eight known quinazolines, were isolated from the MeOH extract of E. rutaecarpa. The new compounds are rare quinazolinedione derivatives with linked heterocyclic nuclei. Among these quinazolines, rhetsinine (8) showed potential as a pesticide and exhibited excellent inhibition against Xanthomonas oryzae pv. oryzae, Xanthomonas oryzae pv. oryzicola, and Xanthomonas campestris pv. campestris, with respective EC50 values of 3.13, 14.32, and 32.72 nmol.

PMID- 29454023 TI - Interaction between hypothermia and delayed mesenchymal stem cell therapy in neonatal hypoxic-ischemic brain injury. AB - Acute hypothermia treatment (HT) is the only clinically established intervention following neonatal hypoxic-ischemic brain injury. However, almost half of all cooled infants still die or suffer from long-lasting neurological impairments. Regenerative therapies, such as mesenchymal stem cells (MSC) appear promising as adjuvant therapy. In the present study, we hypothesized that HT combined with delayed MSC therapy results in augmented protection, improving long-term neurological outcome. Postnatal day 9 (P9) C57BL/6 mice were exposed to hypoxia ischemia followed by 4 h HT. Murine bone marrow-derived MSC (1 * 106 cells/animal) were administered intranasally at P12. Cytokine and growth factor levels were assessed by ELISA and Luminex(r) multiplex assay 24 h following MSC delivery. One week after HI, tissue injury and neuroinflammatory responses were determined by immunohistochemistry and western blot. Long-term motor-cognitive outcome was assessed 5 weeks post injury. MSC responses to the brains' environment were evaluated by gene expression analysis in MSC, co-cultured with brain homogenates isolated at P12. Both, MSC and HT improved motor deficits, while cognitive function could only be restored by MSC. Compared to each single therapy, combined treatment led to increased long-lasting motor-cognitive deficits and exacerbated brain injury, accompanied by enhanced endothelial activation and peripheral immune cell infiltration. MSC co-cultured with brain extracts of HT-treated animals revealed increased pro-inflammatory cytokine and decreased growth factor expression. In vivo protein analysis showed higher pro inflammatory cytokine levels after combined treatment compared to single therapy. Furthermore, HI-induced increase in growth factors was normalized to control levels by HT and MSC single therapy, while the combination induced a further decline below control levels. Our results suggest that alteration of the brains' microenvironment by acute HT modulates MSC function resulting in a pro inflammatory environment combined with alteration of the homeostatic growth factor milieu in the neonatal hypoxic-ischemic brain. This study delineates potential unexpected side effects of cell-based therapies as add-on therapy for acute hypothermia treatment. PMID- 29454025 TI - Early alteration of distribution and activity of hippocampal type-1 cannabinoid receptor in Alzheimer's disease-like mice overexpressing the human mutant amyloid precursor protein. AB - Besides its involvement in Alzheimer's disease (AD) as precursor of the neurotoxic amyloid peptides, the pathophysiological impact of brain accumulation of amyloid precursor protein (APP) is not yet well understood. Recent studies reported that APP interacts with other membrane proteins, including G protein coupled receptors, affecting their biological functions. Here, we focused on the study of the potential impact of human mutant APP on expression, distribution and activity of type-1 cannabinoid (CB1) receptor in the hippocampus of Tg2576 mice, an AD-like mice model. By using biochemical and electrophysiological measures, we found that in a presymptomatic phase, when amyloid plaques have not yet formed and there is no sign of cognitive deficits, the over-expression of full-length APP in the hippocampus of Tg2576 mice altered membrane localization and inhibitory signalling activity of CB1 receptor, possibly by binding to the receptor and reducing its specific interaction with caveolin-1 and G proteins. PMID- 29454024 TI - Development of an in vitro screening method of acute cytotoxicity of the pyrrolizidine alkaloid lasiocarpine in human and rodent hepatic cell lines by increasing susceptibility. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Pyrrolizidine alkaloids (PAs) are secondary plant ingredients formed in many plant species to protect against predators. PAs are generally considered acutely hepatotoxic, genotoxic and carcinogenic. Up to now, only few in vitro and in vivo investigations were performed to evaluate their relative toxic potential. AIM OF THE STUDY: The aim was to develop an in vitro screening method of their cytotoxicity. MATERIALS AND METHODS: Human and rodent hepatocyte cell lines (HepG2 and H-4-II-E) were used to assess cytotoxicity of the PA lasiocarpine. At concentrations of 25 uM up to even 2400 uM, no toxic effects in neither cell line was observed with standard cell culture media. Therefore, different approaches were investigated to enhance the susceptibility of cells to PA toxicity (using high-glucose or galactose-based media, induction of toxifying cytochromes, inhibition of metabolic carboxylesterases, and inhibition of glutathione-mediated detoxification). RESULTS: Galactose-based culture medium (11.1 mM) increased cell susceptibility in both cell-lines. Cytochrome P450-induction by rifampicin showed no effect. Inhibition of carboxylesterase-mediated PA detoxification by specific carboxylesterase 2 inhibitor loperamide (2.5 uM) enhanced lasiocarpine toxicity, whereas the unspecific carboxylesterase inhibitor bis(4-nitrophenyl)phosphate (BNPP, 100 uM)) had a weaker effect. Finally, the inhibition of glutathione-mediated detoxification by buthionine sulphoximine (BSO, 100 uM) strongly enhanced lasiocarpine toxicity in H-4-II-E cells in low and medium, but not in high concentrations. CONCLUSIONS: If no toxicity is observed under standard conditions, susceptibility enhancement by using galactose-based media, loperamide, and BSO may be useful to assess relative acute cytotoxicity of PAs in different cell lines.

AB - A major obstacle in the treatment of human immunodeficiency virus type 1 (HIV-1) is its ability to establish latent infection. To find novel biomarkers associated with the mechanism of HIV-1 latent infection, we identified 70 candidate genes in HIV-1 latently infected cells through the integrated analysis in a previous study. It is important to select more effective biomarkers among 70 candidates and to verify the possibility of selected biomarkers for HIV-1 latency. We identified the 24 and 25 genes from 70 candidate genes in significantly enriched categories selected by Database for Annotation, Visualization and Integrated Discovery (DAVID) software and Gene Set Enrichment Analysis (GSEA) software, respectively. Also, we investigated genes regulated in both HIV-1 latently infected cell lines and PBMCs from HIV-1 infected patients and found the genes with a common pattern of expression levels in both cell lines and PBMCs. Consequently, we identified nine genes, APBB2, GMPR, IGF2BP3, LRP1, MAD2L2, MX1, OXR1, PTK2B, and TNFSF13B, via integrated analysis. Especially, APBB2 and MAD2L2 were identified in both DAVID and GSEA software. Our findings suggest that nine genes were identified via integrated analysis as potential biomarkers and in particular, APBB2 and MAD2L2 may be considered as more significant biomarkers for HIV-1 latency. PMID- 29454026 TI - Adaptation of Escherichia coli to long-term batch culture in various rich media. AB - Experimental evolution studies have characterized the genetic strategies microbes utilize to adapt to their environments, mainly focusing on how microbes adapt to constant and/or defined environments. Using a system that incubates Escherichia coli in different complex media in long-term batch culture, we have focused on how heterogeneity and environment affects adaptive landscapes. In this system, there is no passaging of cells, and therefore genetic diversity is lost only through negative selection, without the experimentally-imposed bottlenecking common in other platforms. In contrast with other experimental evolution systems, because of cycling of nutrients and waste products, this is a heterogeneous environment, where selective pressures change over time, similar to natural environments. We determined that incubation in each environment leads to different adaptations by observing the growth advantage in stationary phase (GASP) phenotype. Re-sequencing whole genomes of populations identified both mutant alleles in a conserved set of genes and differences in evolutionary trajectories between environments. Reconstructing identified mutations in the parental strain background confirmed the adaptive advantage of some alleles, but also identified a surprising number of neutral or even deleterious mutations. This result indicates that complex epistatic interactions may be under positive selection within these heterogeneous environments.

AB - Selective laser sintering (SLS) is a three-dimensional printing (3DP) technology employed to manufacture plastic, metallic or ceramic objects. The aim of this study was to demonstrate the feasibility of using SLS to fabricate novel solid dosage forms with accelerated drug release properties, and with a view to create orally disintegrating formulations. Two polymers (hydroxypropyl methylcellulose (HPMC E5) and vinylpyrrolidone-vinyl acetate copolymer (Kollidon(r) VA 64)) were separately mixed with 5% paracetamol (used as a model drug) and 3% Candurin(r) Gold Sheen colorant; the powder mixes were subjected to SLS printing, resulting in the manufacture of printlets (3DP tablets). Modulating the SLS printing parameters altered the release characteristics of the printlets, with faster laser scanning speeds accelerating drug release from the HPMC formulations. The same trend was observed for the Kollidon(r) based printlets. At a laser scanning speed of 300 mm/s, the Kollidon(r) printlets exhibited orally disintegrating characteristics by completely dispersing in <4 s in a small volume of water. X ray micro-CT analysis of these printlets indicated a reduction in their density and an increase in open porosity, therefore, confirming the unique disintegration behaviour of these formulations. The work reported here is the first to demonstrate the feasibility of SLS 3DP to fabricate printlets with accelerated drug release and orally disintegrating properties. This investigation has confirmed that SLS is amenable to the pharmaceutical research of modern medicine manufacture. PMID- 29454029 TI - Sex-related differences in the association between grip strength and depression: Results from the Irish Longitudinal Study on Ageing. AB - Muscular strength is a modifiable protective factor for mental health across aging populations. Evidence of sex-related differences in its associations with mental health is limited. Therefore, the purpose of this study was to examine sex related differences in cross-sectional and prospective associations between grip strength and depressive symptoms and status. Participants were community dwelling adults (N = 4505; 56.5% female), aged >=50 years. As a measure of muscular strength, grip strength (kg) of the dominant hand was assessed using a hand-held dynamometer at baseline. Participants were divided into sex-specific tertiles. The Center for Epidemiological Studies Depression Scale assessed depressive symptoms at baseline and two years later; a score of >=16 defined caseness of depression. Depressive symptoms were significantly higher among females at baseline (p < 0.001). Prospective models were adjusted for age, sex, waist circumference, social class, smoking, and health status. Among males, the middle and high strength tertiles were non-significantly associated with 32.9% (p = 0.21) and 9.9% (p = 0.74) reduced odds of developing depression, respectively. Among females, the middle and high strength tertiles were non-significantly associated with 28.5% (p = 0.13) and significantly associated with 43.4% (p = 0.01) reduced odds of developing depression, respectively. In the total sample, the middle and high strength tertiles were significantly associated with 31.5% (p = 0.04) and 34.1% (p = 0.02) reduced odds of developing depression, respectively. The interaction between sex and strength was not statistically significant (p = 0.25). The present findings indicated that grip strength was inversely associated with incident depression in older adults, with stronger associations observed among females than males. PMID- 29454030 TI - Using decision thresholds for ranking treatments in network meta-analysis results in more informative rankings. AB - OBJECTIVES: To evaluate how the rank probabilities obtained from network meta analysis (NMA) change with the use of increasingly stringent criteria for the relative effect comparing two treatments which ranks one treatment better than the other. STUDY DESIGN AND SETTING: Systematic survey and reanalysis of published data. We included all systematic reviews (SRs) with NMA from the field of cardiovascular medicine that had trial-level data available, published in Medline up to February 2015. We reran all the NMAs and determined the probabilities of each treatment being the best. For the best treatment, we examined the effect on these probabilities of varying, what we call the decision threshold, the relative effect required to declare two treatments different. RESULTS: We included 14 SRs, having a median of 20 randomized trials and 9 treatments. The best treatments had probabilities of being best that ranged from 38% to 85.3%. The effect of changing the decision thresholds on the probability of a treatment being best varied substantially across reviews, with relatively little decrease (~20 percentage points) in some settings but a decline to near 0% in others. CONCLUSION: Rank probabilities can be fragile to increases in the decision threshold used to claim that one treatment is more effective than another. Including these thresholds into the calculation of rankings may aid their interpretation and use in clinical practice. PMID- 29454031 TI - Expression and characterization of recombinant rattusin, an alpha-defensin related peptide with a homodimeric scaffold formed by intermolecular disulfide exchanges. AB - Rattusin is an alpha-defensin-related peptide isolated from the small intestine of rats. The primary sequence of linear rattusin is composed of 31 amino acids containing five cysteines with a unique spacing pattern. It forms a homodimeric scaffold in which the primary structure occurs in an antiparallel fashion formed by five intermolecular disulfide (SS) bonds. Rattusin is a highly potent antibiotic, which not only exhibits broad-spectrum antimicrobial activity, but also maintains its antimicrobial activity at physiological salt concentrations. Therefore, to develop new antibiotics based on rattusin, structural and functional studies of rattusin should be performed. For this purpose, large amounts of linear rattusin precursor must be obtained through appropriate preparation methods. Therefore, we established a mass production technique for linear rattusin by using recombinant protein expression and purification procedures. We verified that structure and activity of the recombinant rattusin are identical to the chemically synthesized rattusin. The described method for producing recombinant rattusin provides a high yield of rattusin, which can be used to study the biochemical and functional properties of rattusin and for the development of rattusin-based peptide antibiotics. PMID- 29454032 TI - Basal polarization of the immune responses to Streptococcus agalactiae susceptible and resistant tilapia (Oreochromis niloticus). AB - One of the highest priority areas for improvement is the development of effective strategies for decreasing disease mortality levels in aquaculture production, a better understanding of the components of the fish immune system and their functions in the context of pathogen invasion is needed. Tilapia is the most common fish in South China, and Streptococcus agalactiae has become the most serious disease problem for tilapia industry in China. Here, we profiled gene expression differences between tilapia differing in their susceptibility to S. agalactiae both basally (before infection) and at three early timepoints post infection (5 h, 50 h, and 7 d). Between group comparisons revealed 5756 unique genes differentially expressed greater than 2-fold at one or more timepoints. And the resistant fish showed much more strong ability in pathogen recognition, antigen presentation, immune activation, while the susceptible fish showed fast activation of apoptosis. Taken together, the immune profiles expand our knowledge for molecular mechanisms for disease resistance, as well as provide solid molecular resources for further identification of the candidate markers for disease-resistant selection and evaluation of disease prevention and treatment options for tilapia industry. PMID- 29454033 TI - Cause or Coincidence? Spontaneous Hematometra in Young Women Receiving Depomedroxyprogesterone Acetate: A Small Case Series. AB - BACKGROUND: Abdominal pain, secondary amenorrhea, and abnormal uterine bleeding are common gynecologic presentations in adolescence. Rarely this can be associated with an acquired hematometra. Hematometra is a condition of retained blood or clot within the uterus. High-dose progestogenic agents in this age group have been implicated in the accumulation of a hematometra without other explanation. CASES: We present 4 cases of hematometra after depomedroxyprogesterone acetate (DMPA) therapy in previously menstruating adolescents. All 4 presented with abdominal pelvic pain and/or persistent abnormal uterine bleeding, with the diagnosis confirmed via ultrasound. Suction dilation and curettage was required in each case. SUMMARY AND CONCLUSION: DMPA is a possible cause of hematometra and should be considered in anatomically normal young women experiencing pain or abnormal bleeding out of character for typical long-term DMPA use. PMID- 29454034 TI - Add-on high frequency deep transcranial magnetic stimulation (dTMS) to bilateral prefrontal cortex in depressive episodes of patients with major depressive disorder, bipolar disorder I, and major depressive with alcohol use disorders. AB - BACKGROUND: Dorsolateral prefrontal cortex (DLPFC) is critically involved in mood and alcohol use disorders. OBJECTIVE: We aimed to investigate the safety of intervention with add-on bilateral prefrontal high-frequency deep transcranial magnetic stimulation (dTMS) and between-group differences in treatment response in patients with different types of depressive episodes, including major depressive episodes in the course of major depressive disorder (MDD), bipolar disorder, type I (BD-I), and MDD with alcohol use disorder (MDAUD). METHODS: We conducted a 6-month open-label study, involving 82 patients with DSM-5 Depressive Episode. Of these, 41 had diagnosis of MDD, 20 BD-I, and 21 MDAUD. All patients received standard drug treatment and add-on dTMS over the bilateral DLPFC with left prevalence for four weeks, with five sessions in each week. We rated mood state with the Hamilton Depression Rating Scale (HDRS) at baseline, one-month, and six-month follow-up visits. RESULTS: Mean total HDRS scores dropped from 22.8 (SD = 5.9) at baseline to 10.4 (SD = 3.6) at 1 month, to 10.0 (SD = 4.5) at 6 months, while response/remission were 70.73% (N = 58) and 19.51% (N = 16) at 1 month and 76.83% (N = 63) and 32.93% (27) at 6 months, respectively, with no between-group differences. No patient experienced any side effects. CONCLUSIONS: High-frequency DLPFC dTMS was well tolerated and did not significantly differ on improvement of depression in MDD, BD-I, and MDAUD. PMID- 29454035 TI - High and low doses of cocaine intake are differentially regulated by dopamine D2 receptors in the ventral tegmental area and the nucleus accumbens. AB - Dopamine D2 receptors (D2Rs) in the ventral tegmental area (VTA) and the nucleus accumbens (NAc) are associated with vulnerability to addiction; however, whether D2Rs in these two brain regions play differential roles in regulation of drug intake is unknown. Here, we compared the effect of decreased mRNA level of Drd2 in each region on cocaine self-administration in a dose-response function. Drd2 mRNA levels in rat VTA or NAc were knocked down by bilateral microinjection of lentivirus coding shRNAs against rat Drd2 or scrambled shRNA. Drd2 knockdown was persistent and stable between 20 and 90 days after lentiviral infection. Animals were trained to self-administer cocaine 20 days after Drd2 shRNA treatment. Compared to scrambled shRNA treated rats, Drd2 knockdown in the VTA increased cocaine self-administration at all tested doses (0.02-0.56 mg/kg/infusion) producing an upward shift (both the ascending and descending limb) in the dose response curve of cocaine self-administration. In contrast, intra-NAc knockdown increased cocaine self-administration only on the ascending limb of the dose response curve (0.02-0.07 mg/kg/infusion). These data suggest that D2Rs in the VTA, not in the NAc, regulate high-dose cocaine intake. The present study not only demonstrates that low levels of D2Rs in either region increase low doses of cocaine intake, but also reveals for the first time their dissociable roles in limiting high doses of cocaine self-administration. PMID- 29454036 TI - Percutaneous Endovenous Intervention Plus Anticoagulation versus Anticoagulation Alone for Treating Patients with Proximal Deep Vein Thrombosis: A Meta-analysis and Systematic Review. AB - BACKGROUND: Combination treatment with percutaneous endovenous intervention (PEVI) and anticoagulation has been proposed for treating lower-extremity proximal deep vein thrombosis (DVT). We performed a systematic review and meta analysis of randomized controlled trials (RCTs) to assess the effect of PEVI plus anticoagulation versus anticoagulation alone in patients with lower-extremity proximal DVT. METHODS: We systematically searched PubMed, Embase, and the Cochrane Library from inception to May 2016. All RCTs comparing clinical outcomes between additional PEVI and anticoagulation alone were included. The main end points were postthrombotic syndrome (PTS) and major bleeding complications. Secondary outcomes included the iliofemoral patency rate, venous obstruction, and recurrent DVT. We assessed pooled data using a random-effects model. RESULTS: Four RCTs were included. PEVI plus standard anticoagulation compared with anticoagulation alone was associated with a lower rate of PTS (odds ratio [OR] 0.34, 95% confidence interval [CI] 0.18-0.63), significantly higher iliofemoral patency rate at 6 months and 12 months (OR 8.49, 95% CI 1.32-54.60), a lower rate of venous obstruction (OR 0.42, 95% CI 0.20-0.924), and a lower rate of recurrent DVT (OR 0.42, 95% CI 0.20-0.92). However, more major bleeding episodes occurred in the group with catheter-directed thrombolysis (Peto OR 5.86, 95% CI 1.76 19.48). CONCLUSIONS: PEVI plus anticoagulation reduced the occurrence of PTS, recurrent DVT, and venous obstruction. Another advantage is an increased patency rate at 6 and 12 months. The disadvantage is an increased occurrence of major bleeding events. PMID- 29454037 TI - Melatonin attenuates Delta9-tetrahydrocannabinol-induced reduction in rat sperm motility and kinematics in-vitro. AB - The use of Cannabis sativa (CS) has been widely demonstrated to have detrimental effect on male reproductive functions. Despite the well-known existence of endocannabinoid and melatonergic systems in semen, the physiological significance of their interaction is not understood. We recently showed that melatonin exacerbates the CS-induced gonadotoxicity in-vivo. To overcome the limitations associated with our in-vivo studies and further understand the role of cannabinoid-melatonin relationship in sperm functions, this study investigated the in-vitro effect of tetrahydrocannabinol (THC) and/or melatonin on motility and kinematics of capacitating rat sperms. Rat semen was randomly divided into 9 treatment groups (n = 5) as follow: Groups 1-4 were treated with placebo, SR141716 (1 mM), AM-630 (1 mM), and THC (1 mM) respectively. Groups 5-7 were pre treated with SR141716, AM-630, and their combination respectively, followed by THC after 5 min. Group 8 was treated with melatonin (5 mM), while group 9 was treated with THC and melatonin. THC-induced reduction in sperm motility and kinematics were partly inhibited by cannabinoid receptor (CB) 1 or 2 blockade, but abolished by blockade of both CBs. Interestingly, melatonin increased the progressive motility and kinematics of rat sperms when administered alone and also attenuated THC-induced reduction in progressive motility (by 42%) and kinematics. The hyper-activated motility of capacitated sperms treated with cannabinoids and/or melatonin is determined largely by sperm velocities, amplitude of lateral head and beat/cross frequency but less by velocity ratios. Conclusively, the spermatotoxic effect of THC is mediated by CBs 1 and 2 and is ameliorated by melatonin in-vitro. PMID- 29454038 TI - Dendritic cells as cancer therapeutics. AB - The ability of immune therapies to control cancer has recently generated intense interest. This therapeutic outcome is reliant on T cell recognition of tumour cells. The natural function of dendritic cells (DC) is to generate adaptive responses, by presenting antigen to T cells, hence they are a logical target to generate specific anti-tumour immunity. Our understanding of the biology of DC is expanding, and they are now known to be a family of related subsets with variable features and function. Most clinical experience to date with DC vaccination has been using monocyte-derived DC vaccines. There is now growing experience with alternative blood-derived DC derived vaccines, as well as with multiple forms of tumour antigen and its loading, a wide range of adjuvants and different modes of vaccine delivery. Key insights from pre-clinical studies, and lessons learned from early clinical testing drive progress towards improved vaccines. The potential to fortify responses with other modalities of immunotherapy makes clinically effective "second generation" DC vaccination strategies a priority for cancer immune therapists. PMID- 29454039 TI - Effect of long-term selenium supplementation on mortality: Results from a multiple-dose, randomised controlled trial. AB - BACKGROUND: Selenium, an essential trace element, is incorporated into selenoproteins with a wide range of health effects. Selenoproteins may reach repletion at a plasma selenium concentration of ~ 125 ug/L, at which point the concentration of selenoprotein P reaches a plateau; whether sustained concentrations higher than this are beneficial, or indeed detrimental, is unknown. OBJECTIVE: In a population of relatively low selenium status, we aimed to determine the effect on mortality of long-term selenium supplementation at different dose levels. DESIGN: The Denmark PRECISE study was a single-centre, randomised, double-blinded, placebo-controlled, multi-arm, parallel clinical trial with four groups. Participants were 491 male and female volunteers aged 60 74 years, recruited at Odense University Hospital, Denmark. The trial was initially designed as a 6-month pilot study, but supplemental funding allowed for extension of the study and mortality assessment. Participants were randomly assigned to treatment with 100, 200, or 300 ug selenium/d as selenium-enriched yeast or placebo-yeast for 5 years from randomization in 1998-1999 and were followed up for mortality for a further 10 years (through March 31, 2015). RESULTS: During 6871 person-years of follow-up, 158 deaths occurred. In an intention-to-treat analysis, the hazard ratio (95% confidence interval) for all cause mortality comparing 300 ug selenium/d to placebo was 1.62 (0.66, 3.96) after 5 years of treatment and 1.59 (1.02, 2.46) over the entire follow-up period. The 100 and 200 ug/d doses showed non-significant decreases in mortality during the intervention period that disappeared after treatment cessation. Although we lacked power for endpoints other than all-cause mortality, the effects on cancer and cardiovascular mortality appeared similar. CONCLUSIONS: A 300 ug/d dose of selenium taken for 5 years in a country with moderately-low selenium status increased all-cause mortality 10 years later. While our study was not initially designed to evaluate mortality and the sample size was limited, our findings indicate that total selenium intake over 300 ug/d and high-dose selenium supplements should be avoided.

PMID- 29454040 TI - Development of an Unrelated Donor Selection Score Predictive of Survival after HCT: Donor Age Matters Most. AB - Donor factors, in addition to HLA matching status, have been associated with recipient survival in unrelated donor (URD) hematopoietic cell transplantation (HCT); however, there is no hierarchical algorithm that weights the characteristics of individual donors against each other in a quantitative manner to facilitate donor selection. The goal of this study was to develop and validate a donor selection score that prioritizes donor characteristics associated with better survival in 8/8 HLA-matched URDs. Two separate patient/donor cohorts, the first receiving HCT between 1999 and 2011 (n = 5952, c1), and the second between 2012 and 2014 (n = 4510, c2) were included in the analysis. Both cohorts were randomly spilt, 2:1, into training and testing sets. Despite studying over 10,000 URD transplants, we were unable to validate a donor selection score. The only donor characteristic associated with better survival was younger age, with 2-year survival being 3% better when a donor 10 years younger is selected. These results support previous studies suggesting prioritization of a younger 8/8 HLA-matched donor. This large dataset also shows that none of the other donor clinical factors tested were reproducibly associated with survival, and hence flexibility in selecting URDs based on other characteristics is justified. These data support a simplified URD selection process and have significant implications for URD registries. PMID- 29454041 TI - Potential risks of Zika and chikungunya outbreaks in Brazil: A modeling study. AB - OBJECTIVES: While Brazil has witnessed an unprecedented Zika (ZIK) epidemic, chikungunya (CHIK) has also recently come into prominence as a threat in the Americas. The aim of this study was to identify the regions with increased probabilities of ZIK and CHIK occurrence, based on environmental and social conditions. METHODS: A statistical Maxent model was used to assess the potential spatial risk of ZIK and CHIK dissemination; this considered the number of probable autochthonous ZIK and CHIK cases in 2015 and 2016, along with environmental variables and social indicators. RESULTS: Land use was the most significant variable that best defined the distribution of ZIK and CHIK. Of the social variables, garbage destination, type of sanitary installation, and pipe borne water were the most significant. An estimated 65 million people in Brazil live in areas at high risk of ZIK and 75 million people in areas at high risk of CHIK. The southeast and northeast regions of Brazil presented the largest areas of high risk for both ZIK and CHIK. CONCLUSIONS: Many areas across the Brazilian territory are exposed to ZIK or CHIK infection risks, which are related mainly to land use. The study findings offer valuable information to support time-sensitive public health decision-making at the local and national levels. PMID- 29454043 TI - What Is the Role of the Inflammatory Bowel Disease Panel in Diagnosis and Treatment? PMID- 29454045 TI - Transforaminal en bloc resection for the treatment of thoracic ossification of the ligamentum flavum: Retrospective cohort study. AB - BACKGROUND: Our purpose is to introduce transforaminal en bloc resection for the treatment of thoracic ossification of ligamentum flavum, and report outcomes of the procedure. PATIENTS AND METHODS: The record of patients with symptomatic thoracic ossification of the ligamentum flavum who received transforaminal en block resection from October 2010 to September 2014 were retrospectively reviewed. Outcomes were Japanese Orthopaedic Association (JOA) lower extremity motor dysfunction and sphincter dysfunction scores. RESULTS: Seventeen patients (10 males, 7 females) with a median age of 60 years were included in the analysis. Surgery was performed as planned without complications in all patients. One segment decompression was performed in 1 case, 2 segment in 9 cases, 3 segment in 3 cases, and 4 segment in 4 cases. The median lower extremity motor dysfunction score was significantly higher at 2 weeks, 3 months, and 6 months postoperatively, and the end of follow-up, than before surgery (median score: 2, 2, 3, 3, respective, vs. 1, all, p <= 0.008). There were no significant differences in JOA sphincter dysfunction score between the different time points. CONCLUSION: Transforaminal en bloc resection is a safe and effective method for the treatment of thoracic ossification of the ligamentum flavum. PMID- 29454044 TI - The expression patterns of vestigial like family member 4 genes in zebrafish embryogenesis. AB - Transcriptional cofactor Vestigial-like 4 (VGLL4) was considered to take part in the early stage of development. Different from human, three paralogs of vgll4 were found in zebrafish, which were vgll4a, vgll4b and vgll4l. However, the expression patterns of the three paralogs during zebrafish development remains unknown. In this study, we used in situ hybridization to elucidate the temporal and spatial expression of zebrafish vgll4 paralogs during normal embryonic and larval development. Similar expression was shown in certain areas at similar stages for the three paralogs. Expression of vgll4a, vgll4b and vgll4l were all found in pectoral fins and otic vesicles during the early developmental stages. On the other hand, a few differences of the three paralogs expression were found in eyes, pharynx, pharyngeal arches and brain tissues. The expression of vgll4a was weak and ubiquitous, while vgll4b was obviously expressed in brain tissues and vgll4l was clearly restricted to each pair of pharyngeal pouches. What's more, vgll4b and vgll4l had unique expression at mature lateral line neuromasts and forerunner cells respectively. Despite the conservativeness of functional domains, the three paralogs of zebrafish vgll4 shared several similarities and displayed some distinctions in the expression patterns, indicating that they may still have different and exclusive functions, which need to be further explored. PMID- 29454046 TI - The Psychometric Properties of the MBPS Scale Used to Assess Procedural Pain. AB - : The Modified Behavioral Pain Scale (MBPS) was designed to assess procedural pain in infants and is considered valid for assessing immunization pain. The aim of this study was to assess the practical and psychometric properties of the MBPS when applied to other commonly performed procedures. Twenty-six clinicians independently applied the MBPS scale to segments of video collected from 100 infants and children aged 6 to 42 months undergoing 1 of 4 procedures in the emergency department. Positive correlation between MBPS and Visual Analogue Scale observer applied (VASobs) pain (r = .74) was shown and inter- and intrarater reliability coefficients were high (.87 and .89, respectively). Construct validity was shown by scale responsiveness to painful stimuli (4.6 times increase in scores across phases) and the capacity of the scale to distinguish between painful versus nonpainful procedures (P < .001). However, mean baseline scores for procedures were not 0 (likely a function of item descriptors for a "0" score) and the mean difference increased across phases for children with baseline scores >3, which was much lower than for children with scores <3 (P = .0001). Finally, 28% of scores changed after the second viewing of a video segment. The MBPS appears reliable and sensitive to procedural pain when applied by clinicians. Results question the capacity of the scale to differentiate between pain- and nonpain-related distress, the feasibility of this scale, and the appropriateness of item descriptors for medical procedures. PERSPECTIVE: This article presents the psychometric and practical properties of the MBPS applied to assess procedural pain. Identification of a suitable scale for this purpose will support improved pain management in infants and young children who undergo painful procedures. PMID- 29454048 TI - New Insights into the Molecular Characteristics of Pulmonary Carcinoids and Large Cell Neuroendocrine Carcinomas, and the Impact on Their Clinical Management. AB - Carcinoids and large cell neuroendocrine carcinomas (LCNECs) are rare neuroendocrine lung tumors. Here we provide an overview of the most updated data on the molecular characteristics of these diseases. Recent genomic studies showed that carcinoids generally contain a low mutational burden and few recurrently mutated genes. Most of the reported mutations occur in chromatin-remodeling genes (e.g., menin 1 gene [MEN1]), and few affect genes of the phosphoinositide 3 kinase (PI3K)-AKT-mechanistic target of rapamycin gene pathway. Aggressive disease has been related to chromothripsis, DNA-repair gene mutations, loss of orthopedia homeobox/CD44, and upregulation of ret proto-oncogene gene (RET) gene expression. In the case of LCNECs, which present with a high mutation burden, two major molecular subtypes have been identified: one with biallelic inactivation of tumor protein p53 gene (TP53) and retinoblastoma gene (RB1), a hallmark of SCLC; and the other one with biallelic inactivation of TP53 and serine/threonine kinase 11 gene (STK11)/kelch like ECH associated protein 1 gene (KEAP1), genes that are frequently mutated in NSCLC. These data, together with the identification of common mutations in the different components of combined LCNEC tumors, provide further evidence of the close molecular relation of LCNEC with other lung tumor types. In terms of therapeutic options, future studies should explore the association between mechanistic target of rapamycin pathway mutations and response to mechanistic target of rapamycin inhibitors in carcinoids. For LCNEC, preliminary data suggest that the two molecular subtypes might have a predictive value for chemotherapy response, but this observation needs to be validated in randomized prospective clinical trials. Finally, delta like Notch canonical ligand 3 inhibitors and immunotherapy may provide alternative options for patient tailored therapy in LCNEC. PMID- 29454047 TI - Renal perivascular adipose tissue: Form and function. AB - Renal sympathetic activity affects blood pressure in part by increasing renovascular resistance via release of norepinephrine (NE) from sympathetic nerves onto renal arteries. Here we test the idea that adipose tissue adjacent to renal blood vessels, i.e. renal perivascular adipose tissue (RPVAT), contains a pool of NE which can be released to alter renal vascular function. RPVAT was obtained from around the main renal artery/vein of the male Sprague Dawley rats. Thoracic aortic PVAT and mesenteric PVAT also were studied as brown-like and white fat comparators respectively. RPVAT was identified as a mix of white and brown adipocytes, because of expression of both brown-like (e.g. uncoupling protein 1) and white adipogenic genes. All PVATs contained NE (ng/g tissue, RPVAT:524 +/- 68, TAPVAT:740 +/- 16, MPVAT:96 +/- 24). NE was visualized specifically in RPVAT adipocytes by immunohistochemistry. The presence of RPVAT (+RPVAT) did not alter the response of isolated renal arteries to NE compared to responses of arteries without RPVAT (-RPVAT). By contrast, the maximum contraction to the sympathomimetic tyramine was ~2* greater in the renal artery +PVAT versus -PVAT. Tyramine-induced contraction in +RPVAT renal arteries was reduced by the alpha1-adrenoceptor antagonist prazosin and the NE transporter inhibitor nisoxetine. These results suggest that tyramine caused release of NE from RPVAT. Renal denervation significantly (>50%) reduced NE content of RPVAT but did not modify tyramine-induced contraction of +RPVAT renal arteries. Collectively, these data support the existence of a releasable pool of NE in RPVAT that is independent of renal sympathetic innervation and has the potential to change renal arterial function. PMID- 29454049 TI - Emergence of vancomycin-intermediate and -resistant Staphylococcus aureus among methicillin-resistant S. aureus isolated from clinical specimens in the northwest of Iran. AB - OBJECTIVES: The aim of this study was to evaluate the frequency as well as the phenotypic and molecular characteristics of methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant S. aureus (VRSA) isolates from clinical specimens at three university teaching hospitals in Urmia, Northwest Iran, from 2012-2015. METHODS: Following identification of the isolates, antibiotic susceptibility testing was performed. The presence of the mecA, vanA and pvl genes was evaluated, and staphylococcal cassette chromosome mec (SCCmec) typing was performed. RESULTS: A total of 177 S. aureus isolates were collected from various clinical specimens. Antibiotic susceptibility testing revealed high resistance rates to penicillin (98.9%), followed by erythromycin (61.6%). A total of 95 isolates (53.7%) were confirmed as MRSA. Among the initially screened vancomycin-intermediate S. aureus (VISA) isolates, one isolate with a minimum inhibitory concentration (MIC) of 6MUg/mL harboured the vanA gene. Eleven MRSA isolates (11.6%) were also VRSA. A majority (23/95; 24.2%) of MRSA were classified as SCCmec type III. Only 6 MRSA isolates (6.3%) harboured the pvl gene. CONCLUSIONS: This study highlights the presence of MRSA along with VISA and VRSA in our setting. To our knowledge, this is the first report showing that a strain can be defined as VISA phenotypically and as VRSA by molecular analysis. Such a finding raises major concerns with regard to control measures and reliable laboratory tests for screening of resistant strains. PMID- 29454050 TI - When travel is a challenge: Travel medicine and the 'dis-abled' traveller. AB - Travellers with recognised disabilities or the dis-ability to function as required during a trip have been overlooked in the travel medicine literature. This paper provides a starting point for further discussion and research into this neglected traveller population. In contrast, tourism research has explored travel with a disability for some time in order to understand the travellers' needs and to improve services accordingly. The contemporary bio-psycho-social understanding of disability serves as the framework for exploring motivations to travel as well as barriers, such as inter and intrapersonal, economic, structural and attitudinal obstacles. The demands of complex travel planning are acknowledged. Attention is also drawn to the particular issue of acquired disability. The theoretical discussion is complemented by travellers' own accounts using as examples mobility impairment on aeroplanes, sensory impairments, and obesity. These insights should inform high quality travel health care starting with an exploration of the health professionals' own views on such endeavours. Important are appropriate communication skills, an understanding of the travellers'/carers' views, wishes and judgment of abilities, as well as the appreciation of the reason for the trip, destination and planned activities. Challenging may be the need to accept that the traveller/carer will be more knowledgeable about the disability, needs, potential problems and solutions than the health professional. Finally, medical requirements for destination and activity need to be combined with the medical requirements for the dis-abling condition. Scarce literature and increasing numbers of travellers with disabilities should make this field a research priority in travel medicine. Unless there is an absolute medical contraindication, travel health professionals should encourage and support travellers for whom travel is a challenge.

AB - BACKGROUND: The Research Group on Chemotherapy of Tropical Diseases, Japan, introduced artemether-lumefantrine (AL) in late 2002, mainly for treating uncomplicated Plasmodium falciparum malaria. Because AL was on the market in Japan in March 2017, the effectiveness and safety of AL were analyzed to help medical personnel use AL optimally. METHODS: Case report forms submitted by the attending physicians were analyzed. When necessary, direct contact with the attending physicians was made to obtain detailed information. RESULTS: Effectiveness analysis was performed for 62 cases and safety analysis was performed for 66 cases. In P. falciparum malaria, the overall cure rate was 91.1% (51/56), of which the cure rates for Japanese and non-Japanese patients were 82.1% (23/28) and 100% (28/28), respectively. The successfully treated cases included severe P. falciparum malaria, with parasite densities exceeding 500,000/MUL. Adverse events were reported in 14 patients, including delayed hemolytic anemia which occurred in the top four highest parasitemic cases. CONCLUSIONS: AL treatment failure in P. falciparum malaria may not be rare among non-immune individuals, including Japanese. The possibility of delayed hemolytic anemia, which occurs preferentially in high parasitemic cases, should be considered following AL treatment.

PMID- 29454053 TI - Development and characterization of nano biopolymer containing cumin oil as a new approach to enhance antioxidant properties of button mushroom. AB - The aim of present study was to design a controlled release system using Cuminum cyminum essential oil loaded chitosan nanoparticles (CEO-CSNPs) and evaluate its effect on catalase (CAT), glutathione reductase (GR), peroxidase (POD) activity and ascorbic acid content of Agaricus bisporus fruit bodies during 20days of storage at 4 degrees C. The success of encapsulation was evaluated through TEM, DLS, FT-IR and spectrophotometry and its release behavior was studied in buffer solutions with different pH. The CEO-CSNPs exhibited an average size of 30 to 80nm with a spherical shape. Encapsulation efficiency (EE) and loading capacity (LC) were 4.46 to 17.89% and 2.47 to 6.68%, respectively. The highest CAT and GR activity was observed in samples packed with CEO-CSNPs after 15days of storage. In contrast, POD activity reached a peak at the end of storage in control samples. Interestingly, after 20days the level of POD increased 17.13% in CEO CSNPs treatment, as compared with the initial level of the mentioned enzyme. At the end of storage, ascorbic acid content in samples treated with CEO-CSNPs was significantly higher than that detected in the control samples. In brief, application of CEO loaded chitosan nanoparticles in packages effectively increased the antioxidant activity in white button mushroom and showed promising results for extending the shelf life of treated samples.

AB - A powerful system for studying protein aggregation, particularly rapid self assembly, is spider silk. Spider silks are proteinaceous and silk proteins are synthesized and stored within silk glands as liquid dope. As needed, liquid dope is near-instantaneously transformed into solid fibers or viscous adhesives. The dominant constituents of silks are spidroins (spider fibroins) and their terminal domains are vital for the tight control of silk self-assembly. To better understand spidroin termini, we used target capture and deep sequencing to identify spidroin gene sequences from six species representing the araneoid families of Araneidae, Nephilidae, and Theridiidae. We obtained 145 terminal regions, of which 103 are newly annotated here, as well as novel variants within nine diverse spidroin types. Our comparative analyses demonstrated the conservation of acidic, basic, and cysteine amino acid residues across spidroin types that had been proposed to be important for monomer stability, dimer formation, and self-assembly from a limited sampling of spidroins. Computational, protein homology modeling revealed areas of spidroin terminal regions that are highly conserved in three-dimensions despite sequence divergence across spidroin types. Analyses of our dense sampling of terminal regions suggest that most spidroins share stabilization mechanisms, dimer formation, and tertiary structure, despite producing functionally distinct materials. PMID- 29454055 TI - Optimization, chain conformation and characterization of exopolysaccharide isolated from Leuconostoc mesenteroides DRP105. AB - Response surface methodology (RSM) was used to optimize the fermentation condition of exopolysaccharide (EPS) producing strain Leuconostoc mesenteroides DRP105. Result showed that the optimum condition was sucrose 86.83g/L, tryptone 15.47g/L, initial pH7.18 and maximum yield was 53.79+/-0.78g/L in 36h fermentation. Chain conformation was characterized by Congo red test, beta elimination and circular dichroism (CD), which indicated that the EPS was O linkage and exhibited random coil structure in aqueous solution. CD results concluded hydrogen-bond interaction and chirality might be connected with concentration. Purified EPS has a higher degradation temperature of 279.42 degrees C, suggesting high thermal stability of the EPS. The absolute value of zeta potential and particle size were enhanced with increasing concentration. Crude EPS and its purified fraction were found to have moderate DPPH, hydroxyl, superoxide anion radicals scavenging activities and reducing power. This study provided a high yield EPS with unique characteristics for industrial applications. PMID- 29454056 TI - Biophysical and immunological characterization of 2-dRib modified HSA and its implications in diabetes mellitus. AB - Glycoxidation of protein may lead to develop diabetes. In the present study, different concentrations of 2-deoxy d-ribose (2-dRib) were used to modify human serum albumin (HSA). Nitro Blue Tetrazolium (NBT) assay results showed that yield of the fructosamine content was directly proportional to the concentration of 2 dRib. UV and fluorescence spectroscopy results showed an increment in hyperchromicity and decrease in fluorescence intensity of 2-dRib modified HSA as compared to native HSA. Further secondary structural changes were confirmed by UV circular dichroism (UV-CD) and Fourier transform infrared spectroscopy (FT-IR). To evaluate the immunogenicity of 2-dRib modified HSA, rabbits were immunized with native and 2-dRib modified HSA. Modified HSA sera showed high antibodies titre as compared to native HSA. Moreover, the binding affinity of native and modified HSA with diabetic patient's sera has been evaluated by direct binding ELISA. It was found that diabetic patient's sera showed high binding affinity with the modified HSA as compared to native HSA. On the basis of above findings, it can be concluded that 2-dRib is a potential glycating agent that can cause alteration in HSA structure and make HSA more immunogenic that might play a role in onset and progression of diabetes mellitus and its complications. PMID- 29454057 TI - Pullulan suppresses the denaturation of myofibrillar protein of grass carp (Ctenopharyngodon idella) during frozen storage. AB - This study aims to investigate the effect of pullulan on the denaturation of the myofibrillar protein of grass carp (Ctenopharyngodon idella) during frozen storage at -18 degrees C for 30days. Pullulan or commercial cryoprotectant (1g dry weight) were added to 100g of the myofibrillar protein of grass carp (C. idella), respectively, which was frozenly stored at -18 degrees C for 30days, and the changes in the state of unfrozen of water, solubility, Ca2+ adenylpyrophosphatase (ATPase) activity, and sulfhydryl content of myofibrils were monitored during frozen storage. Pullulan addition increased unfrozen water and sulfhydryl contents in the myofibrillar protein and solubility and ATPase activity of the myofibrillar protein compared with those of the control during frozen storage at -18 degrees C. Moreover, the cryoprotective efficiency of pullulan on the myofibrillar protein of grass carp (C. idella) was higher than that of commercial cryoprotectant. PMID- 29454058 TI - Carboxymethyl konjac glucomannan - crosslinked chitosan sponges for wound dressing. AB - In this paper, carboxymethyl konjac glucomannan (CMKGM) was obtained by carboxyl modification of konjac glucomannan. Then CMKGM and chitosan (CS) were crosslinked and freeze-dried to prepare CMKGM/CS composite sponges with different proportions. The structure and micromorphology of CMKGM/CS sponges were investigated by FTIR spectroscopy and SEM. The SEM results showed that the pore structure of the composite sponge gradually increased with the increase of CMKGM content. To assess the applicability of CMKGM/CS composite sponges as wound dressing, the swelling behavior, water vapor transmission rate (WVTR), biocompatibility (cytotoxicity and hemolysis) were analyzed. The results indicated that CMKGM/CS composite sponges possessed high swelling ratio, proper WVTR and good biocompatibility, which might accelerate tissue regeneration. Meanwhile, in vivo experiments demonstrated that CMKGM/CS composite sponges could effectively heal full-layer wound of skin defects of male ICR mice. PMID- 29454059 TI - Towards a regulatory use of alternative developmental neurotoxicity testing (DNT). AB - There is a need for a more effective Developmental Neurotoxicity (DNT) screening which is scientifically driven by the fact that the developing nervous system might be more sensitive to exposures to some hazardous chemical. Additional concern comes from the recent societal concerns that toxic chemicals can contribute to the prevalence of neurodevelopment disabilities. Consequently, hazard identification and actions to reduce exposure to these chemicals is a priority in chemical risk assessment. To reach this goal a cost-efficient testing strategy based on a reliable in-vitro testing battery should be developed. Although this goal is representing a huge challenge in risk assessment, available data and methodologies are supporting the ultimate aim of developing a predictive model able to respond to different regulatory based problem formulations. PMID- 29454060 TI - AOP-DB: A database resource for the exploration of Adverse Outcome Pathways through integrated association networks. AB - The Adverse Outcome Pathway (AOP) framework describes the progression of a toxicity pathway from molecular perturbation to population-level outcome in a series of measurable, mechanistic responses. The controlled, computer-readable vocabulary that defines an AOP has the ability to, automatically and on a large scale, integrate AOP knowledge with publically available sources of biological high-throughput data and its derived associations. To support the discovery and development of putative (existing) and potential AOPs, we introduce the AOP-DB, an exploratory database resource that aggregates association relationships between genes and their related chemicals, diseases, pathways, species orthology information, ontologies, and gene interactions. These associations are mined from publically available annotation databases and are integrated with the AOP information centralized in the AOP-Wiki, allowing for the automatic characterization of both putative and potential AOPs in the context of multiple areas of biological information, referred to here as "biological entities". The AOP-DB acts as a hypothesis-generation tool for the expansion of putative AOPs, as well as the characterization of potential AOPs, through the creation of association networks across these biological entities. Finally, the AOP-DB provides a useful interface between the AOP framework and existing chemical screening and prioritization efforts by the US Environmental Protection Agency. PMID- 29454061 TI - Activation of NLRX1-mediated autophagy accelerates the ototoxic potential of cisplatin in auditory cells. AB - To date, the mechanism (s) underlying the cisplatin-elicited ototoxicity has not been elucidated fully. Nucleotide-binding domain and leucine-rich-repeat containing family member *1 (NLRX1), a cytoplasmic pattern recognition receptor, is tightly related to mitochondrial function, reactive oxygen species (ROS) production, and autophagy. In this work, autophagy alteration, NLRX1 expression, ROS generation and cell injury were investigated correspondingly by immunofluorescence staining, western-blot, TEM, flow cytometry and MTT in HEI-OC1 cells of both NLRX1 overexpression and silencing in response to cisplatin stimulus. We found that NLRX1 expression was increased concurrent with the increase of autophagy activation in HEI-OC1 cells under the cisplatin insult. NLRX1 overexpression led to the amount of accumulation of autophagsomes in HEI OC1 cells in normal condition and a higher activation of autophagy concurrent with cell injury in HEI-OC1 cells treated with cisplatin, whereas, NLRX1 silencing decreased the activation level of autophagy concurrent with increased cell viability in HEI-OC1 cells treated with cisplatin. Mechanistic studies showed that NLRX1 potentiated mitochondrial-derived ROS generation in response to cisplatin exposure. Inhibition of ROS generation significantly prevented autophagy activation and apoptosis both in HEI-OC1cells and cochlear explants treated with cisplatin. The findings from this work reveal that NLRX1 sensitizes auditory cells in vitro to cisplatin-induced ototoxity via autophagic cell death pathway, providing another strategy against cisplatin-induced ototoxity. PMID- 29454062 TI - Laser-assisted delivery of synergistic combination chemotherapy in in vivo skin. AB - The effectiveness of topical drugs for treatment of non-melanoma skin cancer is greatly reduced by insufficient penetration to deep skin layers. Ablative fractional lasers (AFLs) are known to enhance topical drug uptake by generating narrow microchannels through the skin, but information on AFL-drug delivery in in vivo conditions is limited. In this study, we examined pharmacokinetics, biodistribution and toxicity of two synergistic chemotherapy agents, cisplatin and 5-fluorouracil (5-FU), following AFL-assisted delivery alone or in combination in in vivo porcine skin. Detected at 0-120 h using mass spectrometry techniques, we demonstrated that fractional CO2 laser pretreatment (196 microchannels/cm2, 852 MUm ablation depth) leads to rapid drug uptake in 1500 MUm deep skin layers, with a sixfold enhancement in peak cisplatin concentrations versus non-laser-treated controls (5 h, P = 0.005). Similarly, maximum 5-FU deposition was measured within an hour of AFL-delivery, and exceeded peak deposition in non-laser-exposed skin that had undergone topical drug exposure for 5 days. Overall, this accelerated and deeper cutaneous drug uptake resulted in significantly increased inflammatory and histopathological effects. Based on clinical scores and transepidermal water loss measurement, AFL intensified local toxic responses to drugs delivered alone and in combination, while systemic drug exposure remained undetectable. Quantitative histopathologic analyses correspondingly revealed significantly reduced epidermal proliferation and greater cellular apoptosis after AFL-drug delivery; particularly after combined cisplatin + 5-FU exposure. In sum, by overcoming the primary limitation of topical drug penetration and providing accelerated, enhanced and deeper delivery, AFL-assisted combination chemotherapy may represent a promising treatment strategy for non-melanoma skin cancer. PMID- 29454063 TI - Characterization of nanomedicines: A reflection on a field under construction needed for clinical translation success. AB - The nanotechnology revolution offers many expectations for the improvement of medicine treatments. At present, nanomedicine (NM) development is hampered by methodological barriers for a better characterization and a wider understanding of their in vivo behavior. While regulatory agencies setup guidelines to support NM translation from bench to bedside, the gap is still hardly overcome by main nanomedicines. One lever for filling this gap is a better characterization, thus increasing the global knowledge about the NM itself but also validate the confidence in terms of batch to batch reproducibility of such complex nano objects. Here, we review the current methodologies routinely used for clinical release of nanomedicine batches in compliance with official guidelines. We confront them to the extreme sharpness of biological systems and finally discuss future possible orientations for a better characterization of NMs, needed to bridge the gap between physicochemical properties and biological fate. PMID- 29454065 TI - Impact of food additives on the gut-brain axis. AB - The mammalian intestinal tract is heavily colonized with a complex community of micro-organisms, present at a very high density, and containing an estimated amount of 1014 bacteria. The microbiota generally benefits the host, as it plays a central role in maturing the immune system, protecting against infection by entero-pathogens such as Clostridium difficile, and favoring nutrient digestion/energy extraction in our intestine. An altered microbiota, however, can become detrimental and lead to inflammation, metabolic disorders, and even altered behavior/neuroinflammation. While there are many factors involved in regulating the intestinal microbiota composition and the way it interacts with its host, this review will focus on the role played by food additives on host/microbiota relationship. PMID- 29454064 TI - RNA-based micelles: A novel platform for paclitaxel loading and delivery. AB - RNA can serve as powerful building blocks for bottom-up fabrication of nanostructures for biotechnological and biomedical applications. In addition to current self-assembly strategies utilizing base pairing, motif piling and tertiary interactions, we reported for the first time the formation of RNA based micellar nanoconstruct with a cholesterol molecule conjugated onto one helical end of a branched pRNA three-way junction (3WJ) motif. The resulting amphiphilic RNA micelles consist of a hydrophilic RNA head and a covalently linked hydrophobic lipid tail that can spontaneously assemble in aqueous solution via hydrophobic interaction. Taking advantage of pRNA 3WJ branched structure, the assembled RNA micelles are capable of escorting multiple functional modules. As a proof of concept for delivery for therapeutics, Paclitaxel was loaded into the RNA micelles with significantly improved water solubility. The successful construction of the drug loaded RNA micelles was confirmed and characterized by agarose gel electrophoresis, atomic force microscopy (AFM), dynamic light scattering (DLS), and fluorescence Nile Red encapsulation assay. The estimate critical micelle formation concentration ranges from 39 nM to 78 nM. The Paclitaxel loaded RNA micelles can internalize into cancer cells and inhibit their proliferation. Further studies showed that the Paclitaxel loaded RNA micelles induced cancer cell apoptosis in a Caspase-3 dependent manner but RNA micelles alone exhibited low cytotoxicity. Finally, the Paclitaxel loaded RNA micelles targeted to tumor in vivo without accumulation in healthy tissues and organs. There is also no or very low induction of pro-inflammatory response. Therefore, multivalence, cancer cell permeability, combined with controllable assembly, low or non toxic nature, and tumor targeting are all promising features that make our pRNA micelles a suitable platform for potential drug delivery. PMID- 29454066 TI - Walking behavior in a circular arena modified by pulsed light stimulation in Drosophila melanogaster w1118 line. AB - The Drosophila melanogaster white-eyed w1118 line serves as a parental stock, allowing genetic recombination of any gene of interest along with a readily recognizable marker. w1118 flies display behavioral susceptibility to environmental stimulation such as light. It is of great importance to characterize the behavioral performance of w1118 flies because this would provide a baseline from which the effect of the gene of interest could be differentiated. Little work has been performed to characterize the walking behavior in adult w1118 flies. Here we show that pulsed light stimulation increased the regularity of walking trajectories of w1118 flies in circular arenas. We statistically modeled the distribution of distances to center and extracted the walking structures of w1118 flies. Pulsed light stimulation redistributed the time proportions for individual walking structures. Specifically, pulsed light stimulation reduced the episodes of crossing over the central region of the arena. An addition of four genomic copies of mini-white, a common marker gene for eye color, mimicked the effect of pulsed light stimulation in reducing crossing in a circular arena. The reducing effect of mini-white was copy-number-dependent. These findings highlight the rhythmic light stimulation-evoked modifications of walking behavior in w1118 flies and an unexpected behavioral consequence of mini white in transgenic flies carrying w1118 isogenic background. PMID- 29454067 TI - Considering our methods: Methodological issues with rodent models of appetite and obesity research. AB - A large number of animal models are currently used in appetite and obesity research. Because the worldwide incidence of obesity continues to climb, it is imperative that animal models sharing characteristics of human obesity and its co morbidities be used appropriately in the quest for novel preventions or treatments. There is probably no animal model, at least in rodents, that recapitulates all aspects of "common" human obesity and its comorbidities, but rodent models allow insight into specific mechanisms of disease or its consequences. Frequently used obesity models can be partitioned into different categories, the major ones being a) based on mutations or manipulations of one or a few individual genes or b) those in genetically intact animals exposed to obesogenic environments such as, e.g., being maintained on high-fat diets or being raised in small litters. Characteristics of these models include distinct phenotypes of obesity, hyperphagia or changes in energy metabolism, and frequent comorbidities of obesity, like hyperglycemia, insulin resistance or diabetes-like syndromes. This review which is based on a presentation given during the Annual Meeting of the Society for the Study of Ingestive Behavior in July 2017 points out some observations and characteristics of rodent models in obesity and diabetes research. The choice of rodent models discussed here is subjective and based on the author's own experience or on fruitful discussions with colleagues about the pros and cons of specific models. Hence, this review, by no means, is meant to give a complete picture of rodent models used in this type of research, but the review tries to bring up some issues which, in the author's mind, may also be relevant for models not discussed here. For example, by discussing specific mouse and rat models, similarities and differences between mice and rats will be discussed that need to be considered to interpret experimental findings cautiously and in the context of the respective animal model. Knowing which animal model to use means, knowing its limitations. PMID- 29454068 TI - O-GlcNAcylation of RACK1 promotes hepatocellular carcinogenesis. AB - BACKGROUND & AIMS: Aberrant oncogenic mRNA translation and protein O-linked beta N-acetylglucosaminylation (O-GlcNAcylation) are general features during tumorigenesis. Nevertheless, whether and how these two pathways are interlinked remain unknown. Our previous study indicated that ribosomal receptor for activated C-kinase 1 (RACK1) promoted chemoresistance and growth in hepatocellular carcinoma (HCC). The aim of this study is to examine the role of RACK1 O-GlcNAcylation in oncogene translation and HCC carcinogenesis. METHODS: The site(s) of RACK1 for O-GlcNAcylation was mapped by mass spectrometry analysis. HCC cell lines were employed to examine the effects of RACK1 O GlcNAcylation on the translation of oncogenic factors and behaviors of tumor cells in vitro. Transgenic knock-in mice were used to detect the role of RACK1 O GlcNAcylation in modulating HCC tumorigenesis in vivo. The correlation of RACK1 O GlcNAcylation with tumor progression and relapse were analyzed in clinical HCC samples. RESULTS: We found that ribosomal RACK1 was highly modified by O-GlcNAc at Ser122. O-GlcNAcylation of RACK1 enhanced its protein stability, ribosome binding and interaction with PKCbetaII (PRKCB), leading to increased eukaryotic translation initiation factor 4E phosphorylation and translation of potent oncogenes in HCC cells. Genetic ablation of RACK1 O-GlcNAcylation at Ser122 dramatically suppressed tumorigenesis, angiogenesis, and metastasis in vitro and in diethylnitrosamine (DEN)-induced HCC mouse model. Increased RACK1 O GlcNAcylation was also observed in HCC patient samples and correlated with tumor development and recurrence after chemotherapy. CONCLUSIONS: These findings demonstrate that RACK1 acts as key mediator linking O-GlcNAc metabolism to cap dependent translation during HCC tumorigenesis. Targeting RACK1 O-GlcNAcylation provides promising options for HCC treatment. LAY SUMMARY: O-GlcNAcylation of ribosomal receptor for activated C-kinase 1 at the amino acid serine122 promotes its stability, ribosome localization and interaction with the protein kinase, PKCbetaII, thus driving the translation of oncogenes and tumorigenesis of hepatocellular carcinoma. Increased O-GlcNAcylation of ribosomal receptor for activated C-kinase 1 is positively correlated with tumor growth, metastasis and recurrence in patients with hepatocellular carcinoma. PMID- 29454069 TI - Recipient characteristics and morbidity and mortality after liver transplantation. AB - BACKGROUND AND AIMS: Over the last decade, liver transplantation of sicker, older non-hepatitis C cirrhotics with multiple co-morbidities has increased in the United States. We sought to identify an easily applicable set of recipient factors among HCV negative adult transplant recipients associated with significant morbidity and mortality within five years after liver transplantation. METHODS: We collected national (n = 31,829, 2002-2015) and center-specific data. Coefficients of relevant recipient factors were converted to weighted points and scaled from 0-5. Recipient factors associated with graft failure included: ventilator support (five patients; hazard ratio [HR] 1.59; 95% CI 1.48-1.72); recipient age >60 years (three patients; HR 1.29; 95% CI 1.23 1.36); hemodialysis (three patients; HR 1.26; 95% CI 1.16-1.37); diabetes (two patients; HR 1.20; 95% CI 1.14-1.27); or serum creatinine >=1.5 mg/dl without hemodialysis (two patients; HR 1.15; 95% CI 1.09-1.22). RESULTS: Graft survival within five years based on points (any combination) was 77.2% (0-4), 69.1% (5-8) and 57.9% (>8). In recipients with >8 points, graft survival was 42% (model for end-stage liver disease [MELD] score <25) and 50% (MELD score 25-35) in recipients receiving grafts from donors with a donor risk index >1.7. In center specific data within the first year, subjects with >=5 points (vs. 0-4) had longer hospitalization (11 vs. 8 days, p <0.01), higher admissions for rehabilitation (12.3% vs. 2.7%, p <0.01), and higher incidence of cardiac disease (14.2% vs. 5.3%, p <0.01) and stage 3 chronic kidney disease (78.6% vs. 39.5%, p = 0.03) within five years. CONCLUSION: The impact of co-morbidities in an MELD based organ allocation system need to be reassessed. The proposed clinical tool may be helpful for center-specific assessment of risk of graft failure in non-HCV patients and for discussion regarding relevant morbidity in selected subsets. LAY SUMMARY: Over the last decade, liver transplantation of sicker, older patient with multiple co-morbidities has increased. In this study, we show that a set of recipient factors (recipient age >60 years, ventilator status, diabetes, hemodialysis and creatinine >1.5 mg/dl) can help identify patients that may not do well after transplant. Transplanting sicker organs in patients with certain combinations of these characteristics leads to lower survival. PMID- 29454070 TI - Association of polymorphic variants of IL-1beta and IL-1RN genes in the development of Graves' disease in Kashmiri population (North India). AB - PURPOSE: Graves' disease (GD) is a multigenic, organ specific autoimmune disorder with a strong genetic predisposition and IL-1beta has been shown to be involved in its pathogenesis. The present study was aimed to determine the genetic associations between polymorphisms of IL-1beta gene promoter region (-511 T>C) (rs16944), exon 5 (+3954 C>T) (rs1143634) and IL-1RN gene VNTR (rs2234663) polymorphism in patients with GD in ethnic Kashmiri population. METHODS: A total of 135 Graves' disease patients and 150 healthy individuals were included in the study. PCR and PCR-based restriction analysis methods were done for IL-1RNVNTR and IL-1beta gene polymorphisms respectively. RESULTS: We found statistically significant increased frequencies of the C/C + CT genotype (P = 0.001; odds ratio (OR) = 5.04, 95% confidence interval (CI) = 3.02-8.42) and the C allele (P = 0.001; OR = 3.10, 95% CI = 2.14-4.50) in IL-1beta gene promoter polymorphism (rs16944) with GD patients compared to normal controls. Also in the exon 5 (rs1143634), a significant increase in frequency of the C/C homozygous genotype (P = 0.001; OR = 0.18, 95% CI = 0.11-0.30) and C allele (P = 0.001; OR = 0.31, 95% CI = 0.20-0.48) was observed in GD cases as against controls. For IL-1RNVNTR (rs2234663), we didn't observe any significant difference in the allelic and genotypic frequencies between cases and controls. CONCLUSION: Our findings suggest that both promoter and exon polymorphisms of IL-1beta gene have a significant role in the risk of developing GD, whereas IL-1RNVNTR has no association with GD. PMID- 29454071 TI - HLA in North Colombia Chimila Amerindians. AB - HLA-A,-B,-C,-DRB1 and -DQB1 alleles have been studied in Chimila Amerindians from Sabana de San Angel (North Colombian Coast) by using high resolution molecular typing. A frequent extended haplotype was found:HLA-A*24:02-B*51:10-C*15:02 BRB1*04:07-DQB1*03:02 (28.7%) which has also been described in Amerinndian Mayos Mexican population (Mexico, California Gulf, Pacific Ocean). Other haplotypes had already been found in Amerindians from Mexico (Pacific and Atlantic Coast), Peru (highlands and Amazon Basin), Bolivia and North USA. A geographic pattern according to HLA allele or haplotype frequencies is lacking in Amerindians, as already known. Also, five new extended haplotypes were found in Chimila Amerindians. Their HLA-A*24:02 high frequencies characteristic is shared with aboriginal populations of Taiwan; also, HLA-C*01:02 high frequencies are found in New Zealand Maoris, New Caledonians and Kimberly Aborigines from Australia. Finally, this study may show a model of evolutionary factors acting and rising one HLA allele frequency (-A*24:02), but not in others that belong to the same or different HLA loci. PMID- 29454072 TI - Killer cell immunoglobulin-like receptor genotypes in the Turkish population. AB - One hundred eighty-seven healthy and unrelated volunteers from various regions of Turkey were selected for the study. Killer-cell immunoglobulin-like receptors (KIR) genotyping was performed by polymerase chain reaction using commercial sequence-specific oligonucleotide probe (SSOP) kits. Gene frequencies of the Turkish population were determined by direct counting of the positive and negative loci. The genotype data is publicly available in the Allele Frequencies Net Database under the population name "Turkey KIR pop 3" number "3399". PMID- 29454073 TI - The accumulation of assembly intermediates of the mitochondrial complex I matrix arm is reduced by limiting glucose uptake in a neuronal-like model of MELAS syndrome. AB - Ketogenic diet (KD) which combined carbohydrate restriction and the addition of ketone bodies has emerged as an alternative metabolic intervention used as an anticonvulsant therapy or to treat different types of neurological or mitochondrial disorders including MELAS syndrome. MELAS syndrome is a severe mitochondrial disease mainly due to the m.3243A > G mitochondrial DNA mutation. The broad success of KD is due to multiple beneficial mechanisms with distinct effects of very low carbohydrates and ketones. To evaluate the metabolic part of carbohydrate restriction, transmitochondrial neuronal-like cybrid cells carrying the m.3243A > G mutation, shown to be associated with a severe complex I deficiency was exposed during 3 weeks to glucose restriction. Mitochondrial enzyme defects were combined with an accumulation of complex I (CI) matrix intermediates in the untreated mutant cells, leading to a drastic reduction in CI driven respiration. The severe reduction of CI was also paralleled in post-mortem brain tissue of a MELAS patient carrying high mutant load. Importantly, lowering significantly glucose concentration in cell culture improved CI assembly with a significant reduction of matrix assembly intermediates and respiration capacities were restored in a sequential manner. In addition, OXPHOS protein expression and mitochondrial DNA copy number were significantly increased in mutant cells exposed to glucose restriction. The accumulation of CI matrix intermediates appeared as a hallmark of MELAS pathophysiology highlighting a critical pathophysiological mechanism involving CI disassembly, which can be alleviated by lowering glucose fuelling and the induction of mitochondrial biogenesis, emphasizing the usefulness of metabolic interventions in MELAS syndrome. PMID- 29454075 TI - The G protein-coupled P2Y6 receptor promotes colorectal cancer tumorigenesis by inhibiting apoptosis. AB - Colorectal tumors are immersed in an array of tumor-promoting factors including extracellular nucleotides such as uridine 5'-diphosphate (UDP). UDP is the endogenous agonist of the G protein-coupled P2Y6 receptor (P2Y6R), which may contribute to the formation of a tumor-promoting microenvironment by coordinating resistance to apoptosis. Colorectal cancer (CRC) was chemically induced in P2ry6 knockout (P2ry6-/-) mice using azoxymethane and dextran sulfate sodium challenges. Mice were euthanatized and their tumor load determined. Fixed tissues were stained for histological and immunohistochemistry analysis. Tumoroids were also prepared from CRC tumors resected from P2ry6+/+ mice to determine the role of P2Y6R in resistance to apoptosis, whereas HT29 carcinoma cells were used to elucidate the signaling mechanism involved in P2Y6R anti-apoptotic effect. P2ry6 /- mice developed a reduced number of colorectal tumors with apparent tumors having smaller volumes. Overall dysplastic score was significantly lower in P2ry6 /- animals. Stimulation of P2Y6R with the selective agonist MRS2693 protected HT 29 cells from TNFalpha-induced apoptosis. This protective effect was mediated by the stabilizing phosphorylation of the X-linked inhibitor of apoptosis protein (XIAP) by AKT. Using CRC-derived tumoroids, P2Y6R activation was found to contribute to chemoresistance since addition of the P2Y6R agonist MRS2693 significantly prevented the cytotoxic effect of 5-fluorouracil. The present study shows that sustained activation of P2Y6R may contribute to intestinal tumorigenesis by blocking the apoptotic process and by contributing to chemoresistance, a substantial concern in the treatment of patients with CRC. These results suggest that P2Y6R may represent a prime target for reducing colorectal carcinogenesis.

AB - Jaw discrepancies and malrelations affect a large proportion of the general population and their treatment is of utmost significance for individuals' health and quality of life. The aim of their therapy is the modification of aberrant jaw development mainly by targeting the growth potential of the mandibular condyle through its cartilage, and the architectural shape of alveolar bone through a suture type of structure, the periodontal ligament. This targeted treatment is achieved via external mechanical force application by using a wide variety of intraoral and extraoral appliances. Condylar cartilage and sutures exhibit a remarkable plasticity due to the mechano-responsiveness of the chondrocytes and the multipotent mesenchymal cells of the sutures. The tissues respond biologically and adapt to mechanical force application by a variety of signaling pathways and a final interplay between the proliferative activity and the differentiation status of the cells involved. These targeted therapeutic functional alterations within temporo-mandibular joint ultimately result in the enhancement or restriction of mandibular growth, while within the periodontal ligament lead to bone remodeling and change of its architectural structure. Depending on the form of the malrelation presented, the above treatment approaches, in conjunction or separately, lead to the total correction of jaw discrepancies and the achievement of facial harmony and function. Overall, the treatment of craniofacial and jaw anomalies can be seen as an interplay of mechanical forces and adaptations occurring within temporo-mandibular joint and alveolar bone. The aim of the present review is to present up-to-date knowledge on the mechano-biology behind jaw growth modification and alveolar bone remodeling. Furthermore, future molecular targeted therapeutic strategies are discussed aiming at the improvement of mechanically-driven chondrogenesis and osteogenesis. PMID- 29454077 TI - A prospective investigation of neighborhood socioeconomic deprivation and physical activity and sedentary behavior in older adults. AB - Neighborhood conditions may have an important impact on physical activity and sedentary behaviors in the older population. Most previous studies in this area are cross-sectional and report mixed findings regarding the effects of neighborhood environment on different types of physical activity. Moreover, little is known about the prospective relationship between neighborhood environment and sedentary behaviors. Our analysis included 136,526 participants from the NIH-AARP Diet and Health Study (age 51-70). Neighborhood socioeconomic deprivation was measured with an index based on census variables and developed using principal component analysis. Physical activity and sedentary behaviors were measured both at baseline (1995-1996) and follow-up (2004-2006). Multiple regression analyses were conducted to examine the prospective relationship between neighborhood deprivation and exercise, non-exercise physical activity, and sedentary behaviors, adjusting for baseline physical activity and sedentary behaviors as well as potential confounders. We found that more severe neighborhood socioeconomic deprivation was prospectively associated with reduced time for exercise (beta Q5 vs Q1 (95% confidence interval), hour, -0.85 (-0.95, 0.75)) but increased time spent in non-exercise physical activities (1.16 (0.97, 1.34)), such as household activities, outdoor chores, and walking for transportation. Moreover, people from more deprived neighborhoods were also more likely to engage in prolonged (>=5 h/day) TV viewing (Odds ratio Q5 vs Q1 (95% confidence interval), 1.21 (1.15, 1.27)). In conclusion, neighborhood socioeconomic deprivation is associated with physical activity and sedentary behavior in the older population. These associations may differ for different types of physical activities. PMID- 29454074 TI - Nutraceuticals as therapeutic agents for atherosclerosis. AB - Atherosclerosis, a chronic inflammatory disorder of medium and large arteries and an underlying cause of cardiovascular disease (CVD), is responsible for a third of all global deaths. Current treatments for CVD, such as optimized statin therapy, are associated with considerable residual risk and several side effects in some patients. The outcome of research on the identification of alternative pharmaceutical agents for the treatment of CVD has been relatively disappointing with many promising leads failing at the clinical level. Nutraceuticals, products from food sources with health benefits beyond their nutritional value, represent promising agents in the prevention of CVD or as an add-on therapy with current treatments. This review will highlight the potential of several nutraceuticals, including polyunsaturated fatty acids, flavonoids and other polyphenols, as anti CVD therapies based on clinical and pre-clinical mechanism-based studies. PMID- 29454078 TI - Looking for capacities rather than vulnerabilities: The moderating effect of health assets on the associations between adverse social position and health. AB - To increase capacities and control over health, it is necessary to foster assets (i.e. factors enhancing abilities of individuals or communities). Acting as a buffer, assets build foundations for overcoming adverse conditions and improving health. However, little is known about the distribution of assets and their associations with social position and health. In this study, we documented the distribution of health assets and examined whether these assets moderate associations between adverse social position and self-reported health. A representative population-based cross-sectional survey of adults in the Eastern Townships, Quebec, Canada (n = 8737) was conducted in 2014. Measures included assets (i.e. resilience, sense of community belonging, positive mental health, social participation), self-reported health (i.e. perceived health, psychological distress), and indicators of social position. Distribution of assets was studied in relation to gender and social position. Logistic regressions examined whether each asset moderated associations between adverse social position and self reported health. Different distributions of assets were observed with different social positions. Women were more likely to participate in social activities while men were more resilient. Resilience and social participation were moderators of associations between adverse social position (i.e. living alone, lower household income) and self-reported health. Having assets contributes to better health by increasing capacities. Interventions that foster assets and complement current public health services are needed, especially for people in unfavorable situations. Health and social services decision-makers and practitioners could use these findings to increase capacities and resources rather than focusing primarily on preventing diseases and reducing risk factors. PMID- 29454079 TI - A novel metric that quantifies risk stratification for evaluating diagnostic tests: The example of evaluating cervical-cancer screening tests across populations. AB - Our work involves assessing whether new biomarkers might be useful for cervical cancer screening across populations with different disease prevalences and biomarker distributions. When comparing across populations, we show that standard diagnostic accuracy statistics (predictive values, risk-differences, Youden's index and Area Under the Curve (AUC)) can easily be misinterpreted. We introduce an intuitively simple statistic for a 2 * 2 table, Mean Risk Stratification (MRS): the average change in risk (pre-test vs. post-test) revealed for tested individuals. High MRS implies better risk separation achieved by testing. MRS has 3 key advantages for comparing test performance across populations with different disease prevalences and biomarker distributions. First, MRS demonstrates that conventional predictive values and the risk-difference do not measure risk stratification because they do not account for test-positivity rates. Second, Youden's index and AUC measure only multiplicative relative gains in risk stratification: AUC = 0.6 achieves only 20% of maximum risk-stratification (AUC = 0.9 achieves 80%). Third, large relative gains in risk-stratification might not imply large absolute gains if disease is rare, demonstrating a "high-bar" to justify population-based screening for rare diseases such as cancer. We illustrate MRS by our experience comparing the performance of cervical-cancer screening tests in China vs. the USA. The test with the worst AUC = 0.72 in China (visual inspection with acetic acid) provides twice the risk-stratification (i.e. MRS) of the test with best AUC = 0.83 in the USA (human papillomavirus and Pap cotesting) because China has three times more cervical precancer/cancer. MRS could be routinely calculated to better understand the clinical/public-health implications of standard diagnostic accuracy statistics. PMID- 29454081 TI - Do preventive medicine physicians practice medicine? AB - As some preventive medicine physicians have been denied medical licenses for not engaging in direct patient care, this paper attempts to answer the question, "Do preventive medicine physicians practice medicine?" by exploring the requirements of licensure, the definition of "practice" in the context of modern medicine, and by comparing the specialty of preventive medicine to other specialties which should invite similar scrutiny. The authors could find no explicit licensure requirement for either a certain amount of time in patient care or a number of patients seen. No physicians board certified in Public Health and General Preventive Medicine sit on any state medical boards. The authors propose that state medical boards accept a broad standard of medical practice, which includes the practice of preventive medicine specialists, for licensing purposes. PMID- 29454080 TI - Is the childhood home food environment a confounder of the association between child maltreatment exposure and adult body mass index? AB - Childhood maltreatment is consistently associated with adult obesity, leading to calls for tailored weight interventions for people with maltreatment histories. However, it is possible that the maltreatment-obesity association is spurious and driven by unmeasured confounding, in which case such interventions would be misplaced. The home food environment in childhood is a potential confounder, but its role in the association of maltreatment with obesity has not been examined. We used a longitudinal dataset (Project EAT) to examine the association of adult retrospective reports of maltreatment history in childhood (1+ types of maltreatment before age 18 years) with previously-collected prospective childhood reports of home food environment characteristics (availability of healthy foods, availability of sweet/salty snack food, family meal frequency, and food insufficiency). We then estimated the association between maltreatment and adult body mass index (BMI, kg/m2) with and without adjustment for these home food environment factors. After adjustment for sociodemographics, maltreatment had a 0.84 kg/m2 (95% CI: 0.28, 1.41) higher BMI at age 24-39 years, compared to those with no maltreatment, after adjustment for sociodemographics, parenting style, and BMI in childhood. Additional adjustment for home food environment factors had little effect on this association (beta = 0.78 kg/m2; 95% CI: 0.21,1.35), suggesting limited confounding influence of the home food environment factors. Findings provide additional robust evidence that childhood maltreatment is a risk factor for obesity that may warrant tailored interventions. PMID- 29454082 TI - A straightforward STED-background corrected fitting model for unbiased STED-FCS analyses. AB - Combining stimulated emission depletion and fluorescence correlation spectroscopy (STED-FCS) provides a powerful and sensitive tool for studying the molecular dynamics in live cells with high spatio-temporal resolution. STED-FCS gives access to molecular diffusion characteristic at the nanoscale occurring within short period of times. However due to the incomplete suppression of fluorescence in the STED process, the STED-FCS point spread function (PSF) deviates from a Gaussian shape and challenges the analysis of the auto-correlation curves obtained by FCS. Here, we model the effect of the incomplete fluorescence suppression in STED-FCS experiments and propose a new fitting model improving the accuracy of the diffusion times and average molecule numbers measurements. The implementation of a STED module with pulsed laser source on a commercial confocal/FCS microscope allowed us to apply the STED-background corrected model to fit the STED-FCS measurements. The experimental results are in good accordance with the theoretical analysis both for the number of molecules and the diffusion time which decrease accordingly with the STED power. PMID- 29454083 TI - Incidence of Acute Suppurative Sialadenitis in End-Stage Cancer Patients: A Retrospective Observational Study. AB - CONTEXT: Acute suppurative sialadenitis (hereafter referred to as sialadenitis) is accompanied by pain and fever and can diminish the quality of life in end stage cancer patients; however, its incidence is not clear. OBJECTIVES: We conducted this study to elucidate the incidence of sialadenitis in end-stage cancer patients. METHODS: Retrospective review and observational study based on patients' medical records. SUBJECTS: About 726 consecutive cancer patients who died on the palliative care unit of our hospital between April 2012 and November 2016 were included. MEASUREMENTS: Median duration between sialadenitis onset and death, concomitant treatment, average infusion volume per day, site of onset, symptoms, effectiveness of antibiotic treatment, and mean duration until symptomatic relief. RESULTS: The incidence of sialadenitis was 2.9% (21 of 726 cases). The median duration from onset to death was 20 days (range 2-112); concomitant treatment included opioids in 11 patients (55%), anticholinergic drugs in six patients (28%), steroids in three patients (14%), and oxygen inhalation in five patients (23%); average infusion volume per day was 588 +/- 307 mL; site of onset was submandibular gland in 12 patients (57%) and parotid gland in nine patients (42%); and symptoms were pain in 18 patients (85%) and fever in 13 patients (61%). Antibiotic treatment was administered in 18 patients (85%), and the mean duration until symptomatic relief was 4.0 +/- 1.5 days. CONCLUSION: Sialadenitis is a rare complication in end-stage cancer patients; however, it is important to recognize that it can be associated with severe symptoms, including fever and pain. PMID- 29454084 TI - Augmented voluntary consumption of ethanol induced by reward downshift increases locomotor activity of male Wistar rats in the elevated plus maze. AB - Rats exposed to unexpected reward loss increase voluntary oral consumption of ethanol. Such consumption has been assumed to attenuate loss-induced negative affect (called emotional self-medication). To test this assumption, food-deprived male Wistar rats were exposed to 10 sessions of access to 32% sucrose followed by 5 sessions of access to 4% sucrose (reward downshift). A two-bottle preference test was initiated immediately after each consummatory session to assess ethanol intake. The experimental group received access to 2% ethanol and water, whereas the control group received access to two water bottles. On sessions 11, 12, and 15, immediately after the preference test, animals were tested in the elevated plus maze (EPM) for signs of anxiety. Sucrose consumption was reduced after the 32-to-4% sucrose downshift on sessions 11 and 12, but behavior recovered by session 15. Consummatory suppression was followed by increased ethanol intake in the preference test after sessions 11 and 12, but intake was reduced to preshift levels by session 15; no changes were observed in water controls. Finally, general activity (closed-arm entries and total arm entries) in the EPM increased in the ethanol group on session 12, but not on session 15, relative to water controls. The increase in ethanol consumption induced by reward downshift had measurable effects on activity as assessed in the EPM. These results show that voluntary oral 2% ethanol consumption after reward downshift can affect subsequent behavior, but fall short of providing unambiguous evidence that such ethanol consumption reduces negative affect. PMID- 29454085 TI - Effects of orientation and differential reinforcement II: transitivity and transfer across five-member sets. AB - A recent report by Amd et al. (2017) demonstrated that orienting towards successively presented stimulus-stimulus pairs yielded significantly more transitive relations then when those same pairs were differentially reinforced following training for three, 3-member stimulus sets. We build on that work in four important ways. First, transitivity yields produced by Pavlovian and instrumental procedures were compared following training for three 5-member sets (A1-B1-C1-D1-E1, A2-B2-C2-D2-E2, A3-B3-C3-D3-E3), where the 'A' stimuli were emotional faces and all remaining stimuli were nonsense words. Second, our instrumental task here required two orienting/observing responses per trial. Third, we compared differences in multi-nodal transfer following Pavlovian and instrumental relational learning procedures. Finally, we tested whether functioning as 'end terms' in a relational series can mitigate transfer following instrumental conditioning. Transitivity, as measured by sorting tests, was significantly more pronounced following Pavlovian training. Transfer, assessed before and after relational training with two visual analog scales corresponding to valence and arousal dimensions, appeared marginally more robust observed for participants exposed to the Pavlovian condition. Transfer magnitude was positively related with demonstrations of transitivity, regardless of type of conditioning. PMID- 29454086 TI - High prevalence of factor V Leiden and prothrombin G20101A mutations in Kashmiri patients with venous thromboembolism. AB - AIM: The genetic variants of the factor V (G1691A), prothrombin (G20210A) and MTHFR (C677T) genes have been widely implicated as inherited risk factors for developing venous thrombosis. This study was undertaken to reveal the frequency of these mutations in Kashmiri patients with venous thromboembolism. METHODOLOGY: A case-control study was designed with 250 VTE patients and 250 healthy controls. The mutations were analysed using ARMS-PCR and PCR-RFLP approach. RESULT: The factor V Leiden G1691A mutation was found in 17/250 (6.8%) VTE patients and prothrombin G20210A mutation was found in 7/250 (2.8%) VTE patients while no mutation was found in any of the healthy controls. Both the mutations were found to be significantly associated with the increased risk of VTE (p = 0.0001 and 0.0150 respectively) while no association of VTE risk with MTHFR C677T polymorphism was found (p = 0.53). CONCLUSION: The increased frequency of factor V Leiden G1691A and prothrombin G20210A mutation in VTE patients indicates a significant role of these mutations in the development of VTE in our population. We therefore suggest the routine screening of these two mutations as thrombophilic markers in Kashmiri patients with venous thromboembolism. PMID- 29454087 TI - Multi-step splicing of sphingomyelin synthase linear and circular RNAs. AB - The SGMS1 gene encodes the enzyme sphingomyelin synthase 1 (SMS1), which is involved in the regulation of lipid metabolism, apoptosis, intracellular vesicular transport and other significant processes. The SGMS1 gene is located on chromosome 10 and has a size of 320 kb. Previously, we showed that dozens of alternative transcripts of the SGMS1 gene are present in various human tissues. In addition to mRNAs that provide synthesis of the SMS1 protein, this gene participates in the synthesis of non-coding transcripts, including circular RNAs (circRNAs), which include exons of the 5'-untranslated region (5'-UTR) and are highly represented in the brain. In this study, using the high-throughput technology RNA-CaptureSeq, many new SGMS1 transcripts were identified, including both intronic unspliced RNAs (premature RNAs) and RNAs formed via alternative splicing. Recursive exons (RS-exons) that can participate in the multi-step splicing of long introns of the gene were also identified. These exons participate in the formation of circRNAs. Thus, multi-step splicing may provide a variety of linear and circular RNAs of eukaryotic genes in tissues. PMID- 29454088 TI - HSF4 transcriptional regulates HMOX-1 expression in HLECs. AB - The major causes for cataract formation are free radicals, which are neutralized by the endogenous antioxidants. However, how the human lens clean these harmful free radicals is still unclear. Transcriptional factor heat shock factor 4 (HSF4) is a cataract-causing gene and plays important roles during lens development. Here we show that HMOX-1, an anti-oxidase, is a bona fide transcriptional target gene of HSF4 in HLECs (human lens epithelial cells). HSF4 directly binds to the HSE element in HMOX-1 promoter to mediate its mRNA transcription and protein accumulation. The HSE element located at the region of -389 bp to -362 bp upstream from the TSS (transcription start site), which is critical for HMOX-1 transcriptional activation. Furthermore, knockdown of HSF4 by siRNA inhibited HMOX-1 expression. Thus, these data revealed a novel transcription target of HSF4 and provided new insights into anti-oxidation regulation in lens and age-related cataract. PMID- 29454089 TI - Genome-wide gene expression analysis of 45 days pregnant fetal cotyledons vis-a vis non-pregnant caruncles in buffalo (Bubalus bubalis). AB - The crosstalk between fetus and mother starts with the onset of placental attachment to the uterus. The cotyledons and caruncles are the two anatomically distinct structures that play a crucial role in this physiological communication. Using Agilent Gene Chip Genome microarray, we measured the expression profile of pregnancy cotyledons in comparison to caruncular reminiscence of the uteri in non pregnant buffalo (Bubalus bubalis) for the detection of the early post-pregnancy rapid changes in cellular expression of mRNA transcripts. We identified a total of 497 up- and 578 down-regulated genes with <0.05 the FDR corrected p-values using 4 replicates in each group (cotyledons and caruncles) and their role in pregnancy. Deep bioinformatics analysis of data revealed the cluster of genes involved at the placentome level for various functions such as fetus attachment, transport of nutrition, and immune response. Importantly, the pathways like Hedgehog/Calcium/Wnt signalling, cell cycle regulation and immune responses regulatory functions were highly enriched by the differentially identified genes. A very highly up-regulated IL-2 specific gene showed the role of interleukin-2 signalling in the attachment of the embryo. It was observed that the genes responsible for immune response were downregulated, suggesting an immune suppressive environment which is required to adopt the semiallogeneic fetus for a successful pregnancy. To further evaluate and validate the data, we have performed qRT-PCR analysis of twenty-one genes. The present study highlights the repertoire of active transcripts in the junction of cotyledons and caruncles, which are essential for a successful onset and completion of pregnancy. PMID- 29454090 TI - Characterization of vasa homolog in a neotropical catfish, Jundia (Rhamdia quelen): Molecular cloning and expression analysis during embryonic and larval development. AB - We have characterized the full-length vasa cDNA from Jundia, Rhamdia quelen (Heptapteridae, Siluriformes). vasa encodes a member of the DEAD-box protein family of ATP-dependent RNA helicases. This protein is highly conserved among different organisms and its role is associated with RNA metabolism. In the majority of the investigated species, vasa is restricted to the germ cell lineage and its expression has been used to study germline development in many organisms, including fish. The deduced R. quelen vasa amino acid sequence displayed high similarity with Vasa protein sequences from other organisms, and did not cluster with PL10 or P68 DEAD-box protein subfamilies. We also reported that there is no other isoform for vasa mRNA in R. quelen gonads. Expression analysis by RT-PCR and qPCR showed vasa transcripts exclusively expressed in the germ cells of R. quelen gonads. R. quelen vasa mRNA was maternally inherited, and was detected in the migrating primordial germ cells (PGCs) until 264 h post-fertilization during embryonic and larval development. This work has characterized for the first time the full-length R. quelen vasa cDNA, and describes its expression patterns during R. quelen embryonic and larval development. Our results will contribute to the basic reproductive biology of this native species, and will support studies using vasa as a germ cell marker in different biotechnological studies, such as germ cell transplantation. PMID- 29454091 TI - Anlotinib inhibits angiogenesis via suppressing the activation of VEGFR2, PDGFRbeta and FGFR1. AB - Tumor cells recruit vascular endothelial cells and circulating endothelial progenitor cells to form new vessels to support their own growth and metastasis. VEGF, PDGF-BB and FGF-2 are three major pro-angiogenic factors and applied to promote angiogenesis. In this research, we demonstrated that anlotinib, a potent multi-tyrosine kinases inhibitor (TKI), showed a significant inhibitory effect on VEGF/PDGF-BB/FGF-2-induced angiogenesis in vitro and in vivo. Wound healing assay, chamber directional migration assay and tube formation assay indicated that anlotinib inhibited VEGF/PDGF-BB/FGF-2-induced cell migration and formation of capillary-like tubes in endothelial cells. Furthermore, anlotinib suppressed blood vessels sprout and microvessel density in rat aortic ring assay and chicken chorioallantoic membrane (CAM) assay. Importantly, according to our study, the anti-angiogenic effect of anlotinib is superior to sunitinib, sorafenib and nintedanib, which are three main anti-angiogenesis drugs in clinic. Mechanistically, anlotinib inhibits the activation of VEGFR2, PDGFRbeta and FGFR1 as well their common downstream ERK signaling. Therefore, anlotinib is a potential agent to inhibit angiogenesis and be applied to tumor therapy. PMID- 29454092 TI - Analysis of human papillomavirus 16 E6, E7 genes and Long Control Region in cervical samples from Uruguayan women. AB - OBJECTIVE: This study aims to investigate the HPV16 variant distribution by sequence analyses of E6, E7 oncogenes and the Long Control Region (LCR), from cervical cells collected from Uruguayan women, and to reconstruct the phylogenetic relationships among variants. METHODS: Forty-seven HPV16 variants, obtained from women with HSIL, LSIL, ASCUS and NILM cytological classes were analyzed for LCR and 12 were further studied for E6 and E7. Detailed sequence comparison, genetic heterogeneity analyses and phylogenetic reconstruction were performed. RESULTS: A high variability was observed among LCR sequences, which were distributed in 18 different variants. E6 and E7 sequences exhibited novel non-synonymous substitutions. Uruguayan sequences mainly belonged to the European lineage, and only 5 sequences clustered in non-European branches; 3 of them in the Asian-American and North-American linage and 2 in an African branch. Additionally, 6 new variants from European and African clusters were identified. CONCLUSIONS: HPV16 isolates mainly belonged to the European lineage, though strains from African and Asian-American lineages were also identified. Herein is reported for the first time the distribution and molecular characterization of HPV16 variants from Uruguay, providing novel insights on the molecular epidemiology of this infectious disease in the South America. SYNOPSIS: A high variability among HPV 16 isolates mainly belonged to European lineage, provides an extensive sequence dataset from a country with high burden of cervical cancer. PMID- 29454093 TI - Silencing circular RNA hsa_circ_0000977 suppresses pancreatic ductal adenocarcinoma progression by stimulating miR-874-3p and inhibiting PLK1 expression. AB - Circular RNAs (CircRNAs) are a novel type of endogenous noncoding RNAs that regulate target gene expression by interacting with microRNA (miRNA). Emerging evidence shows that dysregulation of circRNAs plays important roles in biological and pathological processes, including cancer development and progression. The functional role of circRNA in PDAC (pancreatic ductal adenocarcinoma) remains to be investigated. In this study, high throughput microarray assay revealed that hsa_circ_0000977 was aberrantly up-regulated in pancreatic cancer tissues; this was also validated by qRT-PCR. Silencing hsa_circ_0000977 suppressed pancreatic cancer cell proliferation and induced cell cycle arrest, which was simulated by hsa-miR-874-3p mimics and blocked by hsa-miR-874-3p inhibitor. Bioinformatics analysis predicted that there is an hsa_circ_0000977/hsa-miR-874-3p/PLK1 (Polo like kinase 1) axis in pancreatic cancer progression. Dual-luciferase reporter system and FISH assay validated the direct interaction of hsa_circ_0000977, hsa miR-874-3p, and PLK1. Western blot verified that inhibition of hsa_circ_0000977 decreased PLK1 expression. Furthermore, silencing hsa_circ_0000977 suppressed pancreatic cancer growth in vivo. Altogether, silencing hsa_circ_0000977 suppresses progression of pancreatic cancer by interacting with hsa-miR-874-3p and decreasing inhibiting PLK1 expression. Our results may provide a promising strategy for future diagnosis and treatment of pancreatic cancer. PMID- 29454094 TI - Synergistic activity of BET inhibitor BI 894999 with PLK inhibitor volasertib in AML in vitro and in vivo. AB - Interactions between a new potent Bromodomain and extraterminal domain (BET) inhibitor BI 894999 and the polo-like kinase (PLK) inhibitor volasertib were studied in acute myeloid leukemia cell lines in vitro and in vivo. We provide data for the distinct mechanisms of action of these two compounds with a potential utility in AML based on gene expression, cell cycle profile and modulation of PD biomarkers such as MYC and HEXIM1. In contrast to BI 894999, volasertib treatment neither affects MYC nor HEXIM1 expression, but augments and prolongs the decrease of MYC expression caused by BI 894999 treatment. In vitro combination of both compounds leads to a decrease in S-Phase and to increased apoptosis. In vitro scheduling experiments guided in vivo experiments in disseminated AML mouse models. Co-administration of BI 894999 and volasertib dramatically reduces tumor burden accompanied by long-term survival of tumor bearing mice and eradication of AML cells in mouse bone marrow. Together, these preclinical findings provide evidence for the strong synergistic effect of BI 894999 and volasertib, warranting future clinical studies in patients with AML to investigate this paradigm. PMID- 29454095 TI - An esophageal adenocarcinoma susceptibility locus at 9q22 also confers risk to esophageal squamous cell carcinoma by regulating the function of BARX1. AB - Genome wide association studies (GWAS) have identified a series of genetic variants associated with the risk of esophageal adenocarcinoma (EAC)/Barrett's esophagus (BE), which was different from those loci for esophageal squamous cell carcinoma (ESCC). It is important to evaluate whether these susceptibility loci for EAC/BE are also implicated in ESCC development. In the current study, we analyzed genetic variants at 3p13, 9q22, 16q24 and 19p13 in a case-control study including 2139 ESCC patients and 2463 cancer-free controls in a Chinese population, and further characterized the biological relevance of genetic variants by functional assays. We found that the G allele of rs11789015 at 9q22, as compared with the A allele, was significantly associated with a decreased risk of ESCC with a per-allele odds ratio of 0.77 (95%CI, 0.65-0.90; P = 1.38 * 10-3), whereas the other three loci were not associated with ESCC risk. We further found that rs11789015-G allele correlated with decreased mRNA and protein levels of BARX1. Dual-luciferase reporter gene assay revealed that the A > G change at rs11789015 significantly decreased the promoter activity of BARX1. Both the mRNA and protein levels of BARX1 were significantly higher in ESCC tumor tissues compared with the corresponding normal tissues. Moreover, the deletion of BARX1 substantially reduced ESCC cells growth, migration and invasion. In conclusion, these results suggest that genetic variants at 9q22 are associated with the risk of both EAC/BE and ESCC, possibly by regulating the function of BARX1.

AB - OBJECTIVE: To provide an overview of janus kinase (JAK), chemoattractant receptor homologous molecule expressed on TH2 cells (CRTH2), and phosphodiesterase 4 (PDE4) inhibitors in allergic disorders. DATA SOURCES: PubMed literature review. STUDY SELECTIONS: Articles included in this review discuss the emerging mechanism of action of small molecule inhibitors and their use in the treatment of atopic dermatitis (AD), asthma, and allergic rhinitis (AR). RESULTS: Allergic diseases represent a spectrum of diseases, including AD, asthma, and AR. For decades, these diseases have been primarily characterized by increased TH2 signaling and downstream inflammation. In recent years, additional research has identified disease phenotypes and subsets of patients with non-Th2 mediated inflammation. The increasing heterogeneity of disease has prompted investigators to move away from wide-ranging treatment approaches with immunosuppressive agents, such as corticosteroids, to consider more targeted immunomodulatory approaches focused on specific pathways. In the past decade, inhibitors that target JAK signaling, PDE4, and CRTH2 have been explored for their potential activity in models of allergic disease and therapeutic benefit in clinical trials. Interestingly, although JAK inhibitors provide an opportunity to interfere with cytokine signaling and could be beneficial in a broad range of allergic diseases, current clinical trials are focused on the treatment of AD. Conversely, both PDE4 and CRTH2 inhibitors have been evaluated in a spectrum of allergic diseases. This review summarizes the varying degrees of success that these small molecules have demonstrated across allergic diseases. CONCLUSION: Emerging therapies currently in development may provide more consistent benefit to patients with allergic diseases by specifically targeting inflammatory pathways important for disease pathogenesis.

AB - Although the possibility of using drug-loaded ophthalmic lens to promote sustained drug release has been thoroughly pursued, there are still problems to be solved associated to the different alternatives. In this work, we went back to the traditional method of drug loading by soaking in the drug solution and tried to optimize the release profiles by changing the temperature and the time of loading. Two materials commercially available under the names of CI26Y and Definitive 50 were chosen. CI26Y is used for intraocular lenses (IOLs) and Definitive 50 for soft contact lenses (SCLs). Three drugs were tested: an antibiotic, moxifloxacin, and two anti-inflammatories, diclofenac and ketorolac. Sustained drug release from CI26Y disks for, at least 15 days, was obtained for moxifloxacin and diclofenac increasing the loading temperature up to 60 degrees C or extending the loading time till two months. The sustained release of ketorolac was limited to about 8 days. In contrast, drug release from Definitive 50 disks could not be improved by changing the loading conditions. An attempt to interpret the impact of the loading conditions on the drug release behavior was done using solid-state NMR and differential scanning calorimetry. These studies suggested the establishment of reversible, endothermic interactions between CI26Y and the drugs, moxifloxacin and diclofenac. The loading temperature had a slight effect on the mechanical and optical properties of drug loaded CI26Y samples, which still kept adequate properties to be used as IOL materials. The in vivo efficacy of CI26Y samples, drug loaded at 60 degrees C for two weeks, was predicted using a simplified mathematical model to estimate the drug concentration in the aqueous humor. The estimated concentrations were found to comply with the therapeutic needs, at least, for moxifloxacin and diclofenac. PMID- 29454099 TI - Two-Stage Hepatectomy vs One-Stage Major Hepatectomy with Contralateral Resection or Ablation for Advanced Bilobar Colorectal Liver Metastases. AB - BACKGROUND: Both 2-stage hepatectomy (TSH) and 1-stage hepatectomy (OSH) represent feasible strategies for resection of advanced bilobar colorectal liver metastases (CLM). However, the influence of the surgical approach on postoperative outcomes and overall survival (OS) is unknown. To define the optimal surgical approach for advanced bilobar CLM requiring right hemihepatectomy, we compared short-term and long-term outcomes after TSH and OSH with contralateral resection or radiofrequency ablation (RFA). STUDY DESIGN: We retrospectively reviewed 227 patients with bilobar CLM, who underwent right or extended right hepatectomy with treatment of synchronous CLM in segments I, II, and/or III, between 1998 and 2015. Postoperative outcomes and OS were compared between patients who underwent TSH and those who underwent OSH. RESULTS: Of the 227 patients, 126 (56%) underwent at least the first stage of TSH, and 101 (44%) underwent OSH, 29 (13%) without RFA and 72 (32%) with RFA. Two-stage hepatectomy was associated with a lower incidence of postoperative major complications (14% vs 26%, p = 0.03) and postoperative hepatic insufficiency (6% vs 20%, p = 0.001) than OSH. The 5-year OS rate was higher for patients assigned to TSH than for those who underwent OSH (35% vs 24%, p = 0.016). Patients who completed both stages of TSH had a higher 5-year OS rate than patients who underwent OSH without RFA (50% vs 20%, p = 0.023) or OSH with RFA (50% vs 24%, p < 0.0001). CONCLUSIONS: In patients with advanced bilobar CLM, TSH is associated with fewer complications than OSH. Both TSH in intention-to-treat analysis and completed TSH in as-treated analysis were associated with better OS than OSH. PMID- 29454098 TI - Quantitative Imaging Features and Postoperative Hepatic Insufficiency: A Multi Institutional Expanded Cohort. AB - BACKGROUND: Post-hepatectomy liver insufficiency (PHLI) is a significant cause of morbidity and mortality after liver resection. Quantitative imaging analysis using CT scans measures variations in pixel intensity related to perfusion. A preliminary study demonstrated a correlation between quantitative imaging features of the future liver remnant (FLR) parenchyma from preoperative CT scans and PHLI. The objective of this study was to explore the potential application of quantitative imaging analysis in PHLI in an expanded, multi-institutional cohort. STUDY DESIGN: We retrospectively identified patients from 5 high-volume academic centers who developed PHLI after major hepatectomy, and matched them to control patients without PHLI (by extent of resection, preoperative chemotherapy treatment, age [+/-5 years], and sex). Quantitative imaging features were extracted from the FLR in the preoperative CT scan, and the most discriminatory features were identified using conditional logistic regression. Percent remnant liver volume (RLV) was defined as follows: (FLR volume)/(total liver volume) * 100. Significant clinical and imaging features were combined in a multivariate analysis using conditional logistic regression. RESULTS: From 2000 to 2015, 74 patients with PHLI and 74 matched controls were identified. The most common indications for surgery were colorectal liver metastases (53%), hepatocellular carcinoma (37%), and cholangiocarcinoma (9%). Two CT imaging features (FD1_4: image complexity; ACM1_10: spatial distribution of pixel intensity) were strongly associated with PHLI and remained associated with PHLI on multivariate analysis (p = 0.018 and p = 0.023, respectively), independent of clinical variables, including preoperative bilirubin and %RLV. CONCLUSIONS: Quantitative imaging features are independently associated with PHLI and are a promising preoperative risk stratification tool. PMID- 29454100 TI - Patient-Centered Outcomes after Laparoscopic Paraesophageal Hernia Repair. AB - BACKGROUND: The aim of this study is to investigate patient-centered quality of life (QOL) outcomes in patients undergoing laparoscopic paraesophageal hernia repair. STUDY DESIGN: We prospectively followed patients who underwent laparoscopic paraesophageal hernia repair between 2009 and 2016. The QOL outcomes were measured using the 36-Item Short Form Health Survey, GERD Health Related Quality of Life, Reflux Symptom Index, and Dysphagia score surveys administered preoperatively and at 3 weeks, 6 months, 1 year, and 2 years postoperatively. Postoperative QOL outcomes were compared with preoperative baseline scores using paired t-tests. RESULTS: Of 314 total patients who underwent laparoscopic paraesophageal hernia repair, 188 with adequate follow-up were included in analysis. Mean age was 69.1 +/- 11.8 years and 22.3% of studied subjects were male. Most of the cohort also underwent laparoscopic fundoplication (95.7%). Prevalent symptoms at initial presentation include heartburn (65.4%) and regurgitation (60.1%). Significant improvements between baseline and all postoperative time points were seen in Reflux Symptoms Index (3 weeks: p < 0.0001, 6 months: p = 0.005, 1 year: p = 0.0004, and 2 years: p = 0.002) and GERD Health Related Quality of Life scores (3 weeks: p < 0.0001, 6 months: p = 0.0019, 1 year: p < 0.0001, and 2 years: p = 0.0003). Dysphagia scores were worse at 3 weeks but lost significance at all other time points. The 36-Item Short Form Health Survey measures of Energy/Fatigue (p = 0.0099), Emotional Well-Being (p = 0.0393), Social Functioning (p = 0.0278), Pain (p = 0.0021), and Role Limitations Due to Physical Health (p = 0.0009) were significantly improved 2 years postoperatively. CONCLUSIONS: Laparoscopic paraesophageal hernia repair results in significantly improved QOL as measured by the 36-Item Short Form Health Survey at both short- and long-term intervals. Additionally, Reflux Symptom Index and GERD Health Related Quality of Life scores improved at all postoperative time points. PMID- 29454101 TI - Venous Thromboembolism after Inpatient Surgery in Administrative Data vs NSQIP: A Multi-Institutional Study. AB - BACKGROUND: Previous studies have documented significant differences between administrative data and registry data in the determination of postoperative venous thromboembolism (VTE). The goal of this study was to characterize the discordance between administrative and registry data in the determination of postoperative VTE. STUDY DESIGN: This study was performed using data from the American College of Surgeons NSQIP merged with administrative data from 8 different hospitals (5 different medical centers) between 2013 and 2015. Occurrences of postoperative vein thrombosis (VT) and pulmonary embolism (PE) as ascertained by administrative data and NSQIP data were compared. In each situation where the 2 sources disagreed (discordance), a 2-clinician chart review was performed to characterize the reasons for discordance. RESULTS: The cohort used for analysis included 43,336 patients, of which 53.3% were female and the mean age was 59.5 years. Concordance between administrative and NSQIP data was worse for VT (kappa 0.57; 95% CI 0.51 to 0.62) than for PE (kappa 0.83; 95% CI 0.78 to 0.89). A total of 136 cases of discordance were noted in the assessment of VT; of these, 50 (37%) were explained by differences in the criteria used by administrative vs NSQIP systems. In the assessment of postoperative PE, administrative data had a higher accuracy than NSQIP data (odds ratio for accuracy 2.86; 95% CI 1.11 to 7.14) when compared with the 2-clinician chart review. CONCLUSIONS: This study identifies significant problems in ability of both NSQIP and administrative data to assess postoperative VT/PE. Administrative data functioned more accurately than NSQIP data in the identification of postoperative PE. The mechanisms used to translate VTE measurement into quality improvement should be standardized and improved. PMID- 29454102 TI - Inflammation as a Possible Link Between Dyslipidemia and Alzheimer's Disease. AB - Alzheimer's disease (AD) is the leading cause of dementia worldwide. This pathological condition is characterized not only by Abeta and tau accumulation in the central nervous system (CNS), but also by inflammation, processes that can lead to neurodegeneration. Besides that, other factors may contribute to the development of AD, such as dyslipidemias. Changes in lipid levels can either influence the activity of enzymes related to the protein deposition that occurs in this pathological condition, or enhance the peripheral and CNS immune responses. Furthermore, cholesterol-associated genes are frequently associated with AD. Here, we extensively reviewed the literature and, based on the existing evidences, we suggest inflammation as an important link between dyslipidemias and AD.

PMID- 29454105 TI - Assessing the repeatability of absolute CMRO2, OEF and haemodynamic measurements from calibrated fMRI. AB - As energy metabolism in the brain is largely oxidative, the measurement of cerebral metabolic rate of oxygen consumption (CMRO2) is a desirable biomarker for quantifying brain activity and tissue viability. Currently, PET techniques based on oxygen isotopes are the gold standard for obtaining whole brain CMRO2 maps. Among MRI techniques that have been developed as an alternative are dual calibrated fMRI (dcFMRI) methods, which exploit simultaneous measurements of BOLD and ASL signals during a hypercapnic-hyperoxic experiment to modulate brain blood flow and oxygenation. In this study we quantified the repeatability of a dcFMRI approach developed in our lab, evaluating its limits and informing its application in studies aimed at characterising the metabolic state of human brain tissue over time. Our analysis focussed on the estimates of oxygen extraction fraction (OEF), cerebral blood flow (CBF), CBF-related cerebrovascular reactivity (CVR) and CMRO2 based on a forward model that describes analytically the acquired dual echo GRE signal. Indices of within- and between-session repeatability are calculated from two different datasets both at a bulk grey matter and at a voxel wise resolution and finally compared with similar indices obtained from previous MRI and PET measurements. Within- and between-session values of intra-subject coefficient of variation (CVintra) calculated from bulk grey matter estimates 6.7 +/- 6.6% (mean +/- std.) and 10.5 +/- 9.7% for OEF, 6.9 +/- 6% and 5.5 +/- 4.7% for CBF, 12 +/- 9.7% and 12.3 +/- 10% for CMRO2. Coefficient of variation (CV) and intraclass correlation coefficient (ICC) maps showed the spatial distribution of the repeatability metrics, informing on the feasibility limits of the method. In conclusion, results show an overall consistency of the estimated physiological parameters with literature reports and a satisfactory level of repeatability considering the higher spatial sensitivity compared to other MRI methods, with varied performance depending on the specific parameter under analysis, on the spatial resolution considered and on the study design. PMID- 29454104 TI - Functional brain connectivity is predictable from anatomic network's Laplacian eigen-structure. AB - How structural connectivity (SC) gives rise to functional connectivity (FC) is not fully understood. Here we mathematically derive a simple relationship between SC measured from diffusion tensor imaging, and FC from resting state fMRI. We establish that SC and FC are related via (structural) Laplacian spectra, whereby FC and SC share eigenvectors and their eigenvalues are exponentially related. This gives, for the first time, a simple and analytical relationship between the graph spectra of structural and functional networks. Laplacian eigenvectors are shown to be good predictors of functional eigenvectors and networks based on independent component analysis of functional time series. A small number of Laplacian eigenmodes are shown to be sufficient to reconstruct FC matrices, serving as basis functions. This approach is fast, and requires no time-consuming simulations. It was tested on two empirical SC/FC datasets, and was found to significantly outperform generative model simulations of coupled neural masses. PMID- 29454106 TI - Binocular vision adaptively suppresses delayed monocular signals. AB - A neutral density filter placed before one eye will produce a dichoptic imbalance in luminance, which attenuates responses to visual stimuli and lags neural signals from retina to cortex in the filtered eye. When stimuli are presented to both the filtered and unfiltered eye (i.e., binocularly), neural responses show little attenuation and no lag compared with their baseline counterpart. This suggests that binocular visual mechanisms must suppress the attenuated and delayed input from the filtered eye; however, the mechanisms involved remain unclear. Here, we used a Steady-State Visual Evoked Potential (SSVEP) technique to measure neural responses to monocularly and binocularly presented stimuli while observers wore an ND filter in front of their dominant eye. These data were well-described by a binocular summation model, which received the sinusoidal contrast modulation of the stimulus as input. We incorporated the influence of the ND filter with an impulse response function, which adjusted the input magnitude and phase in a biophysically plausible manner. The model captured the increase in attenuation and lag of neural signals for stimuli presented to the filtered eye as a function of filter strength, while also generating the filter phase-invariant responses from binocular presentation for EEG and psychophysical data. These results clarify how binocular visual mechanisms-specifically interocular suppression-can suppress the delayed and attenuated signals from the filtered eye and maintain normal neural signals under imbalanced luminance conditions. PMID- 29454107 TI - Archetype modeling methodology. AB - Clinical Information Models (CIMs) expressed as archetypes play an essential role in the design and development of current Electronic Health Record (EHR) information structures. Although there exist many experiences about using archetypes in the literature, a comprehensive and formal methodology for archetype modeling does not exist. Having a modeling methodology is essential to develop quality archetypes, in order to guide the development of EHR systems and to allow the semantic interoperability of health data. In this work, an archetype modeling methodology is proposed. This paper describes its phases, the inputs and outputs of each phase, and the involved participants and tools. It also includes the description of the possible strategies to organize the modeling process. The proposed methodology is inspired by existing best practices of CIMs, software and ontology development. The methodology has been applied and evaluated in regional and national EHR projects. The application of the methodology provided useful feedback and improvements, and confirmed its advantages. The conclusion of this work is that having a formal methodology for archetype development facilitates the definition and adoption of interoperable archetypes, improves their quality, and facilitates their reuse among different information systems and EHR projects. Moreover, the proposed methodology can be also a reference for CIMs development using any other formalism. PMID- 29454109 TI - Comparative evaluation of lignocellulolytic activities of filamentous cultures of monocentric and polycentric anaerobic fungi. AB - Sixteen strains of monocentric and polycentric anaerobic fungi were evaluated for cellulase, xylanase and esterase activities. Though strain level variations were observed among all genera, Neocallimastix and Orpinomyces strains exhibited the highest lignocellulolytic activities. The esterase activities of monocentric group of anaerobic fungi were better than the polycentric group. PMID- 29454108 TI - Detection of B. fragilis group and diversity of bft enterotoxin and antibiotic resistance markers cepA, cfiA and nim among intestinal Bacteroides fragilis strains in patients with inflammatory bowel disease. AB - We compared frequency of the members of B. fragilis group in 100 and 20 colon biopsy specimens of inflammatory bowel disease (IBD) and non-IBD patients. Agar dilution and PCR were orderly used to detect minimal inhibitory concentration of ampicillin, imipenem, and metronidazole, and carriage of related resistance genes cepA, cfi, and nim. B. fragilis group was detected in 38% of IBD (UC: 36/89; CD:1/11) and 25% (5/20) of non-IBD patients. While B. vulgatus (UC: 20/36, CD: 1/2, control: 1/6); B. fragilis (UC: 18/36, CD: 1/2, control: 5/6); B. ovatus (UC: 2/36); B. caccae (UC: 1/36); and B. eggerthii (UC: 1/36) were characterized, colonization of B. thetaiotamicron, B. merdae, B. distasonis, B. stercoris and B. dorei species was not detected in these specimens. Co-existence of B. fragilis + B. vulgatus (5 patients) and B. vulgatus + B. caccae (1 patient) was detected just in UC patients. bft was detected among 31.5% (6/19) of B. fragilis strains in the IBD and 40% (2/5) in the non-IBD groups. Nearly, 73.6% of the strains from the patient group and 80% in control group harbored cepA; 31.5% and 20% in the patients and control groups harbored cfiA, and none of them harbored nim determinant. Co-occurrence of the cepA and cfiA was orderly detected in 10.5% (2/19) and 20% (1/5) of the strains in these groups. The resistance rates were detected as 95.8% (23/24 (to ampicillin (MIC range of <=0.5->=16 MUg/ml), 0% to metronidazole and 29.1% to imipenem (7/24, MIC range <=4-32 MUg/ml). Nearly 25% (6/24) of the strains were resistant to ampicillin and imipenem, simultaneously. No statistically significant difference was detected between the IBD and control groups for drug resistance phenotypes. Statistical analysis showed significant associations between resistance to ampicillin or imipenem and carriage of cepA or cfiA, respectively (p value = 0.0007). PCR results on the extracted plasmids confirmed their roles in carriage of cfiA and cepA. These data provide guide for antibiotic therapy and highlights wide distribution of beta-lactam resistant B. fragilis strains in patients with IBD and non-IBD intestinal disorders. PMID- 29454110 TI - Study of lipid metabolism by estimating the fat fraction in different breast tissues and in various breast tumor sub-types by in vivo 1H MR spectroscopy. AB - PURPOSE: To evaluate the utility of fat fraction (FF) for the differentiation of different breast tissues and in various breast tumor subtypes using in vivo proton (1H) magnetic resonance spectroscopy (MRS). METHODS: 1H MRS was performed on 68 malignant, 35 benign, and 30 healthy volunteers at 1.5 T. Malignant breast tissues of patients were characterized into different subtypes based on the differences in the expression of hormone receptors and the FF was calculated. Further, the sensitivity and specificity of FF to differentiate malignant from benign and from normal breast tissues of healthy volunteers was determined using receiver operator curve (ROC) analysis. RESULTS: A significantly lower FF of malignant (median 0.12; range 0.01-0.70) compared to benign lesions (median 0.28; range 0.02-0.71) and normal breast tissue of healthy volunteers (median 0.39; range 0.06-0.76) was observed. No significant difference in FF was seen between benign lesions and normal breast tissues of healthy volunteers. Sensitivity and specificity of 75% and 68.6%, respectively was obtained to differentiate malignant from benign lesions. For the differentiation of malignant from healthy breast tissues, 76% sensitivity and 74.5% specificity was achieved. Higher FF was seen in patients with ER-/PR- status as compared to ER+/PR+ patients. Similarly, FF of HER2neu+ tumors were significantly higher than in HER2neu- breast tumors. CONCLUSION: The results showed the potential of in vivo 1H MRS in providing insight into the changes in the fat content of different types of breast tissues and in various breast tumor subtypes. PMID- 29454111 TI - Combining Rosetta with molecular dynamics (MD): A benchmark of the MD-based ensemble protein design. AB - Computational protein design is a set of procedures for computing amino acid sequences that will fold into a specified structure. Rosetta Design, a commonly used software for protein design, allows for the effective identification of sequences compatible with a given backbone structure, while molecular dynamics (MD) simulations can thoroughly sample near-native conformations. We benchmarked a procedure in which Rosetta design is started on MD-derived structural ensembles and showed that such a combined approach generates 20-30% more diverse sequences than currently available methods with only a slight increase in computation time. Importantly, the increase in diversity is achieved without a loss in the quality of the designed sequences assessed by their resemblance to natural sequences. We demonstrate that the MD-based procedure is also applicable to de novo design tasks started from backbone structures without any sequence information. In addition, we implemented a protocol that can be used to assess the stability of designed models and to select the best candidates for experimental validation. In sum our results demonstrate that the MD ensemble-based flexible backbone design can be a viable method for protein design, especially for tasks that require a large pool of diverse sequences. PMID- 29454112 TI - Comparative proteomic analysis of the maize responses to early leaf senescence induced by preventing pollination. AB - The aim of this study was to explore the molecular mechanisms of induced leaf senescence by preventing pollination in maize using a proteomic method combined with other physiological methods. An elite maize inbred line Yu816 was selected for evaluation of its senescence mechanism. Phenotypic and chlorophyll content analysis revealed that the onset of leaf senescence occurred earlier in non pollinated (NONPOL) leaves than pollinated (POL) leaves. Leaf protein species of NONPOL and POL leaves were separately extracted and their proteomes were assessed using isobaric tags for relative and absolute quantitation (iTRAQ) analysis. A total of 4371 protein species were identified, of which 809 exhibited differentially altered abundance (P < 0.05). The identified protein species were related to diverse functions including photosystems, plant hormones, cell death, oxidative degradation, and protein metabolism, suggesting a potential signaling cascade for ear leaf senescence induced by pollination prevention. In addition, leaf total soluble sugar and leaf starch contents were remarkably higher in NONPOL plants than in POL plants. These findings suggest that induced leaf senescence might be associated with nutrient remobilization. Our results reveal a network of molecular mechanisms at the protein level and provide some insights into the early senescence mechanism in higher plants. Biological significance: The coordination between growth and timing for senescence is critical for maize production. However, the molecular mechanism of induced leaf senescence by preventing pollination in maize remains to be further elucidated at the proteomic level. Herein, we revealed some new protein species that are involved in hormone signaling, glycometabolism, oxidation-reduction, protein degradation and photosystem breakdown, and other biological processes that were not previously known to be associated with leaf senescence. This is the first large-scale proteomics study to examine induced leaf senescence in maize by preventing pollination. PMID- 29454113 TI - Identification of two novel CRESS DNA viruses associated with an Avipoxvirus lesion of a blue-and-gray Tanager (Thraupis episcopus). AB - The discovery of circular rep-encoding single stranded (CRESS) DNA viruses has increased spectacularly over the past decade. They represent the smallest animal viruses known worldwide infecting a wide variety of invertebrates and vertebrates in different natural and human-made environments. The extremely low similarity of nucleotide and protein sequences among different CRESS DNA genomes has challenged their classification. Moreover, the existence of capsid proteins (Cp) remains difficult to demonstrate which is crucial to understand the structural properties of these viruses. Here we describe two unclassified CRESS DNA viruses isolated from a cutaneous lesion, caused by a strain of Avipoxvirus, from a blue-and-gray tanager (Thraupis episcopus) in Southern Ecuador. Both viruses present replication-associated proteins (Rep) and one to two open reading frames (ORF), one of which represents a putative Cp. The two new Rep are long proteins characterized by the existence of the several highly conserved amino acid residues characteristic of rolling circle replication. Within the putative Cp we detected intrinsically disordered regions (IDR), potential protein and DNA binding regions, and nuclear localization signals (NLS), providing further evidence of presumed Cp. Despite being found on the same host lesion, both viruses show low similarity between each other (<60%) and other known CRESS DNA viruses. Furthermore, we analyze the evolutionary relationships within the CRESS DNA diversity. Additional sampling is needed to explore the possible pathogenic effects, prevalence and diversity (both phylogenetical and structural) of these viruses in wild bird populations. PMID- 29454114 TI - Mitochondria: Targeting mitochondrial reactive oxygen species with mitochondriotropic polyphenolic-based antioxidants. AB - Mitochondrial function and regulation of redox balance is fundamental in controlling cellular life and death pathways. Antioxidants have been used to counteract disruption of redox networks, normally associated with progressive loss of cell homeostasis and disease pathophysiology, although therapeutic success is limited mainly due to pharmacokinetic drawbacks. Attempts to improve mitochondrial function in a range of diseases spurred active drug discovery efforts. Currently, the most effective strategy to deliver drugs to mitochondria is the covalent link of lipophilic cations to the bioactive compound. Although targeting mitochondrial oxidative stress with antioxidants has been demonstrated, clinical use has been hampered by several challenges, with no FDA-approved drug so far. Development of new mitochondriotropic antioxidant agents based on dietary polyphenols has recently gained momentum. Due to their nature, mitochondria targeted multi-functional antioxidants can trigger stress responses and contribute to tissue protection through hormesis mechanisms, inhibiting excessive mitochondrial ROS production and associated diseases. PMID- 29454115 TI - Traumatic Spinal Injury: Global Epidemiology and Worldwide Volume. AB - BACKGROUND: Traumatic spinal injury (TSI) results from injury to bony, ligamentous, and/or neurologic structures of the spinal column and can cause significant morbidity and mortality. The global burden of TSI is poorly understood, so we performed a systematic review and meta-analysis to estimate the global volume of TSI. METHODS: We performed a systematic review through PubMed, Embase, and Cochrane Databases on TSI studies reported from 2000 to 2016. Collected data were used to perform a meta-analysis to estimate the annual incidence of TSI across World Health Organization regions and World Bank income groups using random-effect models. Incorporating global population figures, the annual worldwide volume of TSI was estimated. RESULTS: A total of 102 studies were included in the systematic review and 19 studies in the meta-analysis. The overall global incidence of TSI was 10.5 cases per 100,000 persons, resulting in an estimated 768,473 [95% confidence interval, 597,213-939,732] new cases of TSI annually worldwide. The incidence of TSI was higher in low- and middle-income countries (8.72 per 100,000 persons) compared with high-income countries (13.69 per 100,000 persons). Road traffic accidents, followed by falls, were the most common mechanism of TSI worldwide. Overall, 48.8% of patients with TSI required surgery. CONCLUSIONS: TSI is a major source of morbidity and mortality throughout the world. Largely preventable mechanisms, including road traffic accidents and falls, are the main causes of TSI globally. Further investigation is needed to delineate local and regional TSI incidences and causes, especially in low- and middle-income countries. PMID- 29454116 TI - Cyst with a Twist! Diagnostic Dilemma. AB - Obstructive hydrocephalus secondary to posterior cranial fossa space-occupying lesions is common, and treatment includes shunting or removal of the causative lesion. The list of posterior fossa space-occupying lesions is exhaustive and includes tumors, cysts, and tumor-like conditions. In the setting of cancer, the first differential is usually a metastatic deposit. However, unrelated pathologies could coexist and may be overlooked. We hereby describe an unusual case of a posterior fossa cystic, suspected metastatic lesion presenting with moderate to severe hydrocephalus in a patient with oral cavity cancer on chemotherapy, which turned out to be cysticercosis on excision, leading to a diagnostic dilemma; hence the adage "cyst with a twist"! PMID- 29454117 TI - The Differentially Expressed Genes of Human Sporadic Cerebral Cavernous Malformations. AB - OBJECTIVES: To understand the development of sporadic cerebral cavernous malformations (SCCM) comprehensively, we analyzed gene expression profiles in SCCMs by gene microarray. METHODS: The total number of the specimens collected in our study was 14, 7 of which were SCCMs, and the others were controls that were obtained from normal brain vessels. The total RNA was extracted and hybridized with oligonucleotide array containing 21522 genes. The analysis of Gene Ontology (GO) items and molecular pathways was performed based on the GO and Kyoto Encyclopedia of Genes and Genomes databases. The gene coexpression networks were constructed to identify the core genes regulating the progression of SCCMs. RESULTS: A total of 785 probes, showing differentially expressed genes (DEGs) between the 2 groups, were found by the gene chips. According to the analysis based on GO and Kyoto Encyclopedia of Genes and Genomes, 286 GO terms and 53 pathways were identified to be significantly relevant with the DEGs. All differential gene interactions were analyzed and the core genes were selected in the coexpression networks. CONCLUSIONS: The gene expression profiles obtained from SCCMs were significantly distinct from those of control brain vascular specimens. These DEGs are related to multiple molecular signal pathways, such as the mitogen-activated protein kinase pathway, cytokine-cytokine receptor interaction, focal adhesion, and inflammatory response. According to the analysis of the core genes selected in the gene coexpression networks, we postulated that CSF1R, XCL1, KCNMB1, RHOG, and TJP1 might exert enormous functions in the pathogenesis of SCCMs. However, further studies are required to aid in the clinical diagnosis and prevention of SCCMs. PMID- 29454118 TI - The Factors Affecting the Difficulty of Percutaneous Cylindrical Electrode Placement for Spinal Cord Stimulation. AB - OBJECTIVE: Optimal placement of electrodes is important for spinal cord stimulation. Factors affecting the difficulty of percutaneous electrode placement are not well known. In this study, we retrospectively evaluated the factors affecting the difficulty of percutaneous electrode placement. METHODS: We performed a retrospective analysis of 90 consecutive procedures of percutaneous cylindrical electrode implantation at the first author's institution. Age, sex, smoking state, body mass index, the duration of time from the beginning of pain syndrome to operation, diagnosis, the number of previous electrode placements, the previous electrode implantation period, the presence of axial low back pain, the electrode tip level, the pattern of electrode placement, and the reason for reimplantation were selected as factors associated with the success of electrode placement or the operation time of electrode placement. RESULTS: The number of previous electrode placements and the electrode tip level were independently associated with the operation time of electrode placement. According to both univariable and multivariable regression analyses, 1 previous electrode placement lengthened the operation time by approximately 15 minutes. No factors were significantly associated with the success of electrode placement. The more frequently that previous electrode placement was performed, the more difficult electrode placement tended to be. However, electrode reimplantation can be successful given extra time. CONCLUSIONS: This is the first study to evaluate factors affecting the difficulty of percutaneous electrode placement. A history of percutaneous cylindrical electrode placement did not affect the success of current placement, although it lengthened the operation time. PMID- 29454119 TI - Anatomic Study of Nutrient Foramina of Posterior Axis with Application to C2 Pedicle Screw Placement. AB - OBJECTIVE: Pedicle screws placed into C2 necessitate a thorough understanding of this bone's unique anatomy. Although multiple landmarks and measurements have been used by surgeons, these are often varied in the literature with no consensus. Herein, we studied one recently proposed landmark using the nutrient foramina of the posterior aspect of C2 for pedicle screw placement. METHODS: On 19 (38 sides) C2 dry bone specimens, the presence, size, location, and distance from the midline of the nutrient foramina found at the junction between the isthmus and lamina were documented and measured. In addition, to discern the source of the artery entering such foramina, an injected adult cadaver was dissected. RESULTS: The number of foramina ranged from 0-5 with a mean of 1.84. On 3 sides, no foramina were identified. The mean diameter of the foramina was 0.57 mm. The location of the foramina was at position 1 on 9.5% of sides, position 2 on 66.4% of sides, and position 3 on 24.1% of sides. The mean horizontal distance from the midline of the spinous process of C2 to the foramina was 25.17 mm. In the cadaveric specimen, the source of the artery entering these C2 nutrient foramina was found to be distal branches of the deep cervical artery. CONCLUSIONS: We found the nutrient foramina of the C2 laminae are useful for pedicle screw placement. However, there are minor variations of the number and position of these structures. Lastly, on the basis of our study, 7.9% (n = 3) of sides will not have such foramina. PMID- 29454120 TI - Optic Nerve Atrophy Due to Long-Standing Compression by Planum Sphenoidale Meningioma. AB - PURPOSE: In this study we report an uncommon endoscopic endonasal image of an atrophic optic nerve as seen after surgical removal of a suprasellar meningioma. The peculiarity of this case is the long-lasting underestimated ocular symptomatology of the patient who reported a 15-year history of impairment of vision on her left eye. METHODS: A 51-year-old woman was admitted to our hospital complaining of a 15-year history of impairment of vision on her left eye. After making serendipitously the diagnosis of a suprasellar mass, we performed endoscopic endonasal surgery. RESULTS: The tumor was reached from below and removed safely, without manipulation of the optic pathways. At the end of tumor removal, the impressive left optic nerve atrophy due to enduring local tumor compression was visualized. CONCLUSIONS: To the best of our knowledge, no endoscopic endonasal image with such features has been provided in the pertinent literature. Possibly, this contribution will help identify damaged optic nerves during endoscopic endonasal surgery. PMID- 29454121 TI - Complications of Impulse Generator Exchange Surgery for Deep Brain Stimulation: A Single-Center, Retrospective Study. AB - BACKGROUND: Nonrechargeable deep brain stimulation impulse generators (IGs) with low or empty battery status require surgical IG exchange several years after initial implantation. The aim of this study was to investigate complication rates after IG exchange surgery and identify risk factors. METHODS: We retrospectively analyzed complications following IG exchange surgery from 2008 to 2015 in our department. Medical records of all patients who underwent IG exchange surgery were systematically reviewed. The shortest follow-up time was 19 months. RESULTS: From 2008 to 2015, 438 IGs were exchanged in 319 patients. Overall complication rate was 8.90%. Infection developed in 12 patients (2.74%). Six patients (1.37%) experienced local wound erosions. Hardware malfunctions were present in 11 patients (2.51%), and local hemorrhage was observed in 3 cases (0.68%). Repeated fixation of the IG was required in 2 patients (0.46%). Traction of the connecting cables necessitated surgical revision in 2 patients (0.46%). In 2 cases (0.46%), the IG was placed abdominally or exchanged for a smaller device owing to patient discomfort resulting from the initial positioning. One 80-year-old patient (0.23%) had severely worsening heart failure and died 4 days after IG exchange surgery. CONCLUSIONS: IG exchange surgery, although often considered a minor surgery, was associated with a complication rate of approximately 9% in our center. Patients and physicians should understand the complication rates associated with IG exchange surgery because this information might facilitate selection of a rechargeable IG. PMID- 29454122 TI - Rope Jumping-Induced Traumatic Compression Fractures: the Underestimated Danger of Repetitive Axial Load Forces. AB - A non-osteoporotic adult presented with multilevel compression fractures at the apex of the thoracic kyphosis after strenuous rope jumping. Magnetic resonance imaging demonstrated diffuse bone marrow changes in the vertebral bodies with only a small unilateral endplate fracture. Besides highlighting the oftentimes neglected role of repetitive subpathological axial load forces in traumatic spinal injuries, the observed imaging pattern substantiates previous experimental studies which demonstrated that under cyclic axial loading the initial damage occurs in the cancellous regions of the bone (with observation of cracks with average length between 50-100 MUM), ultimately leading to a reduction in its elastic modulus. This pathophysiological mechanism, in which unmitigated propagation of trabecular microscopic cracks through the vertebral bone marrow precedes endplate fractures, may provide a rationale for recent proposals of targeted cement-augmentation in traumatic compression fractures with cement injection directed toward the regions of bone marrow changes. PMID- 29454123 TI - Cardiac Metastasis from Clivus Chordoma. AB - BACKGROUND: Chordomas are rare tumors showing locally aggressive nature and high rates of local recurrences. Distant metastases are infrequently reported and cardiac metastases are extremely rare. CASE DESCRIPTION: A 32-year-old woman had been diagnosed with a large chordoma involving the clivus. She received a total removal of the tumor and adjuvant intensity-modulated radiotherapy. Four and a half years after the surgery, she presented with multifocal lesions in the ventricles and the right atrium, although an open thoracotomy revealed chronic inflammation. Two years after finding the cardiac lesions, thoracoscopic biopsy of the chest wall lesion revealed metastatic chordoma. She received palliative imatinib for 2 weeks before she died of tumor progression. CONCLUSION: This case illustrates the metastatic potential of clivus chordoma, and the heart can be a site of metastasis. PMID- 29454124 TI - Brainstem Dose Constraints in Nonisometric Radiosurgical Treatment Planning of Trigeminal Neuralgia: A Single-Institution Experience. AB - BACKGROUND: CyberKnife stereotactic radiosurgery (SRS) for trigeminal neuralgia (TGN) administers nonisometric, conformational high-dose radiation to the trigeminal nerve with risk of subsequent hypoesthesia. METHODS: We performed a retrospective, single-institution review of 66 patients with TGN treated with CyberKnife SRS to compare outcomes from 2 distinct treatment periods: standard dosing (n = 38) and reduced dosing (n = 28). Standard and reduced dosing permitted a maximum brainstem dose of 45 Gy and 25 Gy, respectively, each with a prescription dose of 60 Gy. Primary and secondary outcomes were Barrow Neurologic Institute pain and numbness scores. Maximum brainstem dose, prepontine nerve length, and treatment history were recorded for their predictive contributions by logistic regression. RESULTS: After matching, patients in the standard dosing and reduced dosing groups were followed for a median of 25 months and 19.5 months, respectively. Mean trigeminal nerve length was 8.55 mm in the standard dosing group and 9.46 mm in the reduced dosing group. Baseline rates of poorly controlled pain were 97% and 88%, respectively, which improved to 23.4% and 8.3%, respectively (P < 0.001 for both). The baseline rates of bothersome numbness were null in both groups, and increased to 25% in the standard group (P = 0.006) and to 21% in the reduced group (P = 0.07). Regression analyses suggested that reduced brainstem exposure (P = 0.01), as well as a longer trigeminal nerve (P = 0.01), were predictive of durable pain control. CONCLUSIONS: These outcomes demonstrate that a lower maximum brainstem dose can provide excellent pain control without affecting facial numbness. Longer nerves may achieve better long term outcomes and help optimize individual plans. PMID- 29454125 TI - Management of Skull Base Tumors in the Obstetric Population: A Case Series. AB - BACKGROUND: Neoplasms rarely present during pregnancy; however, increases in plasma volume, hormone release-induced growth, and tumor hypervascularity can cause rapidly progressive symptoms of varying severity, ranging from those not requiring intervention to those necessitating emergent operations. Here we describe an algorithm for the management of symptomatic neoplasms in the obstetric population and provide recommendations for surgical indications and timing. METHODS: Patients who presented to the skull base clinic at a large tertiary care hospital between 2010 and 2016 were reviewed to identify those who presented with a skull base tumor during pregnancy. RESULTS: Our study cohort comprised 9 women with a skull base tumor during pregnancy. Four patients presented with symptoms that necessitated emergent skull base surgery, and 5 underwent surgery after delivery or were followed with continued surveillance. All operated patients had a World Health Organization grade I or II meningioma or schwannoma. There were no maternal complications. Based on our experience with this cohort, we have created a management algorithm. CONCLUSIONS: Management of a symptomatic tumor during pregnancy requires balancing the potential for curing the mother and the risk of harming the fetus. Trimester of pregnancy is the most critical factor in evaluating the need for urgent management. The second trimester is the optimal time for surgery, associated with the lowest risk for spontaneous abortion or preterm birth. The first and third trimesters are associated with increased risk of miscarriage and preterm labor, respectively. Induction of labor for preterm delivery, followed by surgery, may be appropriate in the early third trimester. Regardless of the perceived risk, however, all pregnant women with an emergent presentation should be offered surgery, regardless of trimester. PMID- 29454126 TI - Iatrogenic Spondylolisthesis Following Open Lumbar Laminectomy: Case Series and Review of the Literature. AB - OBJECTIVE: To present diagnosis and surgical management of postlaminectomy spondylolisthesis in patients without preoperative instability and a review of relevant literature. METHODS: Medical records and radiographic studies of 105 patients who underwent first-time bilateral 1- to 4-level open laminectomies for degenerative lumbar disease at a single academic institution were reviewed. Patients who initially presented with listhesis and had additional discectomy or fusion procedures were excluded. RESULTS: Of 105 patients with laminectomies across 1-4 levels, 10 patients (9.5%; 5 men and 5 women with average age of 63.0 +/- 11.2 years) developed subsequent iatrogenic spondylolisthesis at the same operative levels that required reoperation. New or worsening low back pain and lower extremity pain were reported over an average period of 19.0 +/- 17.5 months postoperatively. Imaging studies showed new spondylolisthesis that was not present before the index surgery, most commonly at L4-L5 level. All patients were treated surgically with posterior instrumented fusion. The average period between the first and second surgery was 32.6 +/- 19.9 months. Surgical reduction of spondylolisthesis resulted in significant clinical improvement of patients' symptoms. CONCLUSIONS: In patients without overt pre-existing instability, laminectomy for lumbar stenosis can disrupt spinal stability and result in iatrogenic spondylolisthesis. The extent of decompression of the facet joints, number of levels decompressed, and preoperative disc space height can help assess the risk of postoperative spondylolisthesis. Patients who develop recurrent radiculopathy after decompressive lumbar laminectomy should be evaluated for potential iatrogenic spondylolisthesis. PMID- 29454127 TI - Neurosurgery on a Pregnant Woman with Post Mortem Fetal Extrusion: An Unusual Case from Medieval Italy. AB - Trepanation is one of the most ancient and applied surgical treatments; several archaeologically documented cases are known, dated back from prehistory to the Middle Ages. This case study reports the anthropologic analysis of the skeletal remains of a young medieval woman and a fetus (Imola, Italy). The fetal remains were laid between her pelvis and lower limbs. A perforating injury was observed to her frontal bone. After assessing biologic profiles, we attempted to interpret the injury and to reconstruct possible circumstances of death. The lesion seems commensurate with a surgical intervention; signs of an osteogenic reaction were detected at its edges. It can be hypothesized that the survival of the woman undergoing the surgery was approximately 1 week and the fetus extruded after the burial. Thus, this case represents a unicum, spreading more light on the history of neurosurgery during the Early Middle Ages in Europe. PMID- 29454129 TI - Delayed Posttraumatic Subacute Lumbar Subarachnoid Hematoma: Case Report and Review of the Literature. AB - BACKGROUND: Traumatic spinal subarachnoid hematoma, associated or not with a concurrent subdural hematoma, has rarely been described. The evolution of such hematomas is heterogeneous. This study aims at defining the most accurate management, which is currently not standardized. CASE DESCRIPTION: A 20-year-old man, victim of a high-kinetic road accident 5 days before and with several nonneurologic nonsurgical vertebral fractures, experienced a sudden dorsolumbar pain radiating to his lower limbs. A rapidly progressive asymmetric paraparesis with loss of reflexes was noticed, associated with bilateral global hypoesthesia of the lower limbs and with acute urinary retention, whereas the anal tonicity was preserved (American Spinal Injury Association C). Magnetic resonance imaging scan revealed a conus medullaris compression at the level of the L1-L2 vertebrae by an intradural expansive mass. Immediate surgical decompression revealed a strictly subarachnoid hematoma. Venous bleeding was seen at the level of the conus medullaris and controlled. Pathologic examination of the clot excluded an underlying tumor or vascular abnormality. The complete coagulation profile was normal. CONCLUSION: Six weeks after surgery, the neurologic examination revealed only a slight tactile hypoesthesia of the left thigh. With only 4 reported cases, purely subarachnoid spinal hematomas remain widely rarer than epidural hematomas. The reported case possesses a certain number of peculiarities: young age, pure subarachnoid location, lumbar location, occurrence after a car accident, subacute onset, and excellent neurologic recovery. In our opinion, a symptomatic subarachnoid spinal hematoma should be surgically evacuated at the early phase so neurologic recovery can be expected. PMID- 29454128 TI - Preoperative 3-Dimensional Angiography Data and Intraoperative Real-Time Vascular Data Integrated in Microscope-Based Navigation by Automatic Patient Registration Applying Intraoperative Computed Tomography. AB - OBJECTIVE: To establish a workflow integrating preoperative 3-dimensional (3D) angiography data and intraoperative real-time vascular information in microscope based navigation for aneurysm and arteriovenous malformation (AVM) surgery. METHODS: In 7 patients (3 with AVMs and 4 with aneurysms), preoperative 3D rotational angiography or computed tomography (CT) or magnetic resonance angiography data were navigated applying a 32-slice movable CT scanner for low dose registration scanning. The 3D vasculature was segmented and visualized by microscope-based navigation along with navigated intraoperative real-time imaging data from indocyanin green angiography and duplex ultrasonography. RESULTS: Automatic registration applying intraoperative CT resulted in high accuracy (registration error, 0.80 +/- 0.79 mm). The effective radiation dose of the registration CT scans (0.28-0.42 mSv) was only approximately one-sixth of a standard diagnostic head CT scan. The 3D vessel architecture could be visualized accurately in the operating microscope heads-up display and on the navigation screens in the same projection as the view angle of the surgeon, both facilitating orientation in 3D space, providing a better understanding of anatomy. In addition, intraoperative real-time modalities could be coregistered with high precision, providing further information during the course of the vascular procedure. CONCLUSIONS: Registration CT imaging facilitates integrating preoperative and intraoperative vascular image data with a low registration error and low radiation exposure for the patient, improving the understanding of 3D vascular anatomy during surgery with easier identification of feeding vessels in AVMs, and of the projection and configuration of aneurysms. PMID- 29454130 TI - Abscess within a Glioblastoma: Mimicking a Matryoshka Doll. AB - BACKGROUND: Abscess coexisting within a brain tumor is rare. Case reports in the literature primarily consist of sellar pathology and parenchymal lesions, including meningioma, glioma, and metastases. We report a case of glioblastoma with an intratumoral abscess in a middle-aged patient with no prior invasive procedure or systemic focus of infection. CASE DESCRIPTION: A 45-year-old woman presented with new-onset generalized seizures and rapidly progressive left hemiparesis. Imaging showed a right frontal necrotic lesion with a peripherally enhancing wall and solid component posteriorly. There was no diffusion restriction within the lesion. She was afebrile, and there was no systemic focus of infection. With provisional diagnosis of malignant glioma, she underwent surgical resection of the lesion. A differential diagnosis of abscess was considered preoperatively because of the rapid increase in size of the lesion. At surgery, there was a pus-filled cavity with a few areas of grayish, soft, flimsy wall and thrombosed veins. This raised a strong suspicion of a coexisting abscess within a malignant glioma, which was confirmed by histopathologic and microbiologic examination. CONCLUSIONS: It is important for neurosurgeons to be aware of this rare entity. The treatment protocol remains controversial and is primarily guided by expert opinion. It is important to aggressively treat the patient with antibiotics followed by adjuvant therapy for malignancy. The timing and administration of adjuvant therapy are unclear. We suggest a delay of chemotherapy until at least 4 weeks of therapy with sensitive antibiotics. PMID- 29454131 TI - Self-Reported Headaches in Patients with Unruptured Intracranial Aneurysms Treated with the Pipeline Embolization Device. AB - INTRODUCTION: The objective of this study was to analyze patients' perceptions of their headaches both before and after Pipeline flow diversion treatment of their unruptured intracranial aneurysms, with the goal of identifying prognostic factors associated with headache patterns to improve predictions of overall outcomes. METHODS: We retrospectively identified 133 patients treated with the Pipeline embolization device (PED) between January 1, 2014, and December 31, 2016, at an academic institution in the United States. Patients with at least 6 months of clinical follow-up, who had completed a validated telephone survey assessing their headache perceptions before and after treatment of their UIAs, were included. RESULTS: Sixty patients (57.7%) responded to the questionnaire. Median aneurysm size was 6.3 mm. Thirty-two patients (53.3%) presented with headaches before treatment, which had a median intensity of 7 out of 10 (range, 3 10). On postprocedural evaluation, 8 patients (25%) had complete resolution of their headaches. Of the 24 (75%) patients with persistent headaches, the frequency and severity of the headaches decreased or remained the same in most (58.3%) patients. Eleven (18.3%) patients had new-onset headaches. This study found an association between aneurysm size and a reduction in headache frequency and severity after PED treatment. No significant association was found between headache persistence, severity, or frequency and patient demographics, aneurysm characteristics, and other comorbidities. CONCLUSION: An overall improvement of headaches in patients with UIAs who underwent treatment with the PED was observed, particularly in patients harboring large aneurysms and who had presented with daily headaches.

AB - The complement cascade participates in protection against bacterial infections, and pathogens, including Bordetella pertussis, have developed complement-evading strategies.

PMID- 29454133 TI - Prevalence and risk factors for neural axis anomalies in idiopathic scoliosis: a systematic review. AB - BACKGROUND: There is ongoing controversy about the routine use of magnetic resonance imaging (MRI) preoperatively in patients with presumed idiopathic scoliosis (IS). Routine MRI can help identify possible causes for the deformity and detect anomalies that could complicate deformity surgery. However, routine MRI increases health-care costs significantly and may reveal mild variations from normal findings without clinical relevance, which can still lead to anxiety and influence decision-making. PURPOSE: Given the necessity to make evidence-based decisions both in the light of quality of care and cost control, the aim of this review is to report the prevalence of neural axis anomalies in IS and to identify risk factors associated with these anomalies. STUDY DESIGN: A systematic review was carried out. METHODS: An electronic search of PubMed, Embase, Cochrane, and Cinahl until May 2017 was performed. Studies were assessed by two reviewers independently according to predetermined inclusion (MRI in presumed IS) and exclusion criteria (diagnosis other than IS). RESULTS: Fifty-one studies were included comprising 8,622 patients. In 981 patients, anomalies were found, resulting in an overall prevalence of 11.4%. The prevalence was 10.5%, 9.0%, and 14.2% when screening was performed of all IS patients, preoperative patients, or patients with presumed risk factors. The prevalence of a syrinx (3.7%), an Arnold Chiari malformation (3.0%), or a combination of both (2.5%) was highest. Less frequent diagnoses included tethered cord (0.6%), an incidental malignancy (0.3%), and split cord malformations (0.2%). Risk factors for intraspinal anomalies included early-onset scoliosis, male gender, atypical curves, thoracic kyphosis, and abnormal neurologic findings such as reflexes and sensation. CONCLUSIONS: This systematic review shows that a significant number of patients have intraspinal anomalies on preoperative MRI in (presumed) IS. The prevalence of finding spinal axis abnormalities increases in preselected patient groups with specific risk factors. PMID- 29454134 TI - Back pain improves significantly following discectomy for lumbar disc herniation. AB - BACKGROUND CONTEXT: Although lumbar disc herniation (LDH) classically presents with lower extremity radiculopathy, there are patients who have substantial associated back pain. PURPOSE: The present study aims to determine if patients with LDH with substantial back pain improve with decompression alone. STUDY DESIGN: This is a longitudinal observational cohort study. PATIENT SAMPLE: Patients enrolled in the Quality and Outcomes Database with LDH and a baseline back pain score of >=5 of 10 who underwent single- or two-level lumbar discectomy only. OUTCOME MEASURES: Back and leg pain scores (0-10), Oswestry Disability Index (ODI), and EuroQoL 5D were measured. METHODS: Standard demographic and surgical variables were collected, as well as patient-reported outcomes at baseline and at 3 and 12 months postoperatively. RESULTS: The mean age of the cohort was 49.8 years and 1,195 (52.8%) were male. Mean body mass index was 30.1 kg/m2. About half of the patients (1,103, 48.8%) underwent single-level discectomy and the other half (1,159, 51.2%) had two-level discectomy. Average blood loss was 44 cc. Most of the patients (2,217, 98%) were discharged home with routine postoperative care. The average length of stay was 0.53 days. At 3 and 12 months postoperatively, there were statistically significant (p<.000) improvements in back pain (from 7.7 to 2.9 to 3.2), leg pain (from 7.5 to 2.3 to 2.5), and ODI (from 26.2 to 11.6 to 11.2). Patients with a single-level discectomy, compared with patients with a two-level discectomy, had similar improvements in 3- and 12-month back pain, leg pain, and ODI scores. CONCLUSIONS: Patients with LDH who have substantial back pain can be counseled to expect improvement in their back pain scores 12 months after a discectomy. PMID- 29454135 TI - Short-term outcomes following posterior cervical fusion among octogenarians with cervical spondylotic myelopathy: a NSQIP database analysis. AB - BACKGROUND CONTEXT: Degenerative changes in the cervical spine occur in an age dependent manner. As the US population continues to age, the incidence of age dependent, multilevel, degenerative cervical pathologies is expected to increase. Similarly, the average age of patients with cervical spondylotic myelopathy (CSM) will likely trend upward. Posterior cervical fusion (PCF) is often the treatment modality of choice in the management of multilevel cervical spine disease. Although outcomes following anterior cervical fusion for degenerative disease have been studied among older patients (aged 80 years and older), it is unknown if these results extend to octogenarian patients undergoing PCF for the surgical management of CSM. PURPOSE: The present study aimed to quantify surgical outcomes following PCF for the treatment of CSM among the octogenarian patient population compared with patients younger than 80 years old. STUDY DESIGN/SETTING: This was a retrospective study that used the National Surgical Quality Improvement Program (NSQIP). PATIENT SAMPLE: The sample included patients aged 60-89 who had CSM and who underwent PCF from 2012 to 2014. OUTCOME MEASURES: The outcome measures were multimorbidity, prolonged length of stay (LOS), discharge disposition (to home or skilled nursing/rehabilitation facility), 30-day all-cause readmission, and 30 day reoperation. METHODS: The NSQIP database was queried for patients with CSM (International Classification of Disease, Ninth Revision, Clinical Modification code 721.1) aged 60-89 who underwent PCF (Current Procedural Terminology code 22600) from 2012 to 2014. Cohorts were defined by age group (60-69, 70-79, 80 89). Data were collected on gender, race, elective or emergent status, inpatientor outpatient status, where patients were admitted from (home vs. skilled nursing facility), American Society of Anesthesiologists class, comorbidities, and single- or multilevel fusion. After controllingfor these variables, logistic regression analysis was used to compare outcome measures in the different age groups. RESULTS: A total of 819 patients with CSM who underwent PCF (416 aged 60-69, 320 aged 70-79, and 83 aged 80-89) were identified from 2012 to 2014. Of the PCF procedures, 79.7% were multilevel. There were no significant differences in the odds of multimorbidity, prolonged LOS, readmission, or reoperation when comparing octogenarian patients with CSM with patients aged 60 69 or 70-79. Patients aged 60-69 and 70-79 were significantly more likely to be discharged to home than patients over 80 (odds ratio [OR] 4.3, 95% confidence interval [CI] 1.8-10.4, p<.0001, and OR 2.7, 95% CI 1.1-6.4, p=.0005, respectively). CONCLUSIONS: Compared with patients aged 60-69 and 70-79, octogenarian patients with CSM were significantly more likely to be discharged to a location other than home following PCF. After controlling for patient comorbidities and demographics, 80- to 89-year-old patients with CSM who underwent PCF did not differ in other outcomes when compared with the other age cohorts. These results can improve preoperative risk counseling and surgical decision-making. PMID- 29454136 TI - What is fast ventricular tachycardia, and whether to worry about it. PMID- 29454137 TI - Mechanisms and management of refractory ventricular arrhythmias in the age of autonomic modulation. AB - Ventricular arrhythmias are responsible for hundreds of thousands of deaths every year. Catheter ablation of ventricular tachycardia (VT) is an essential component of the management of these life-threatening arrhythmias. However, in many patients, despite medical and interventional therapy, VT recurs. Furthermore, some VT substrates (mid-myocardial, left ventricular summit, and intraseptal) are not easily targeted because of limitations of currently available technology. In certain clinical settings, ventricular fibrillation (VF) episodes that have premature ventricular contraction triggers can also be targeted with catheter ablation. However, in most patients there is no clear VF trigger to target, and therefore polymorphic VT or VF cannot be adequately treated with catheter ablation. The autonomic nervous system plays a crucial role in all aspects of ventricular arrhythmias, yet interventions specific to the cardiac neuronal axis have been largely underutilized. This underutilization has been most pronounced in patients with structural heart disease. However, there is a growing body of literature on the physiology and pathophysiology of cardiac neural control and the benefits of neuromodulation to treat refractory ventricular arrhythmias in these patients. We present case-based examples of neuromodulatory interventions currently available and a review of the literature supporting their use. PMID- 29454138 TI - Prognostic implications of early monomorphic and non-monomorphic tachyarrhythmias in patients discharged with acute coronary syndrome. AB - BACKGROUND: The prognostic implication of early ventricular tachyarrhythmias (VTs) after acute coronary syndrome (ACS) remains unclear. OBJECTIVE: We sought to investigate the clinical outcomes of early monomorphic and non-monomorphic VTs that occur within 48 hours in patients after ACS. METHODS: We retrospectively reviewed the clinical outcomes of 2033 [mean age 67.0 +/- 13.4 years; 1486 (73.1%) men] consecutive patients who presented with ACS from 2004 to 2015. RESULTS: A total of 67 (3.3%) and 90 (4.4%) patients developed early monomorphic or non-monomorphic VT, respectively. Killip class IV (odds ratio [OR] 3.05; 95% confidence interval [CI] 1.47-6.36; P < .01), creatine kinase level (OR 1.01; 95% CI 1.00-1.02 per 100 IU/L; P = .01), and left ventricular ejection fraction (OR 0.96; 95% CI 0.94-0.99; P < .01) were independently associated with early monomorphic VT, whereas age (OR 0.98; 95% CI 0.97-0.99; P = .04), ST elevated myocardial infarction (OR 3.53; 95% CI 1.71-7.27; P < .01), Killip class IV (OR 4.91; 95% CI 2.76-8.74; P < .01), diabetes mellitus (OR 0.48; 95% CI 0.28-0.81; P < .01), and left ventricular ejection fraction (OR 0.97; 95% CI 0.95-0.99; P < .01) were independently associated with early non-monomorphic VT. More patients with early monomorphic VT (n = 22 [32.8%]) died in hospital than those with non monomorphic VT (n = 16 [17.8%]) or without early VT (n = 133 [7.1%]; P < .01). After a mean follow-up of 67.8 +/- 43.2 months, 21 patients with early monomorphic VT (46.7%), 22 patients with early non-monomorphic VT (29.7%), and 552 patients without early VT (31.7%) died. Both early monomorphic and non monomorphic VTs were associated with a long-term increase in sudden arrhythmic deaths and recurrent VTs. Nevertheless, only early monomorphic VT was shown to independently predict overall survival (hazard ratio 1.62; 95% CI 1.03-2.55; P = .04). CONCLUSION: Early monomorphic VT, but not early non-monomorphic VT, independently predicted all-cause mortality in patients with ACS who survived to hospital discharge.

PMID- 29454141 TI - A cluster randomized pilot trial of a tailored worksite smoking cessation intervention targeting Hispanic/Latino construction workers: Intervention development and research design. AB - Construction workers have the highest smoking rate among all occupations (39%). Hispanic/Latino workers constitute a large and increasing group in the US construction industry (over 2.6 million; 23% of all workers). These minority workers have lower cessation rates compared to other groups due to their limited access to cessation services, and lack of smoking cessation interventions adapted to their culture and work/life circumstances. Formative research was conducted to create an intervention targeting Hispanic/Latino construction workers. This paper describes the intervention development and the design, methods, and data analysis plans for an ongoing cluster pilot two-arm randomized controlled trial comparing an Enhanced Care worksite cessation program to Standard Care. Fourteen construction sites will be randomized to either Enhanced Care or Standard Care and 126 participants (63/arm) will be recruited. In both arms, recruitment and intervention delivery occur around "food trucks" that regularly visit the construction sites. Participants at Enhanced Care sites will receive the developed intervention consisting of a single face-to-face group counseling session, 2 phone calls, and a fax referral to Florida tobacco quitline (QL). Participants at Standard Care sites will receive a fax referral to the QL. Both groups will receive eight weeks of nicotine replacement treatment and two follow up assessments at three and six months. Feasibility outcomes are estimated recruitment yield, barriers to delivering the intervention onsite, and rates of adherence/compliance to the intervention, follow-ups, and QL enrollment. Efficacy outcomes are point-prevalence and prolonged abstinence rates at six month follow up confirmed by saliva cotinine <15 ng/ml.

Rural health clinics offer a potential venue for delivery of weight management. However, traditional programs require travel to attend on-site meetings which is impractical or inconvenient for rural residents. Clinic staff in most rural settings are unlikely to be trained to provide effective weight management. Remote delivery using group phone conferences (GP) or individual phone calls (IP), by staff associated with rural clinics eliminates the need for travel to attend on-site meetings. The effectiveness of these approaches will be the focus of this trial. Staff at five primary care clinics, serving primarily rural residents, will be trained to deliver GP and IP interventions and an enhanced usual care (EUC), (i.e., individual face-to-face meetings (~45 min) at clinic site, four times across 18 mos.). Two hundred overweight/obese adults (BMI >= 25.0-45.0 kg/m2, age >= 21 yrs.) will be recruited through each clinic and randomized to GP (n = 80), IP (n = 80), or EUC (n = 40) to compare weight loss (0 6 mos.), weight maintenance (7-18 mos.), and weight change during a 6 mo. no contact follow-up (19-24 mos.) between intervention arms. The GP and IP interventions will be identical in lesson plan content, diet, and physical activity. The only difference between groups will be the delivery format (group vs. individual) and session duration (GP ~45 min/session; IP ~15 min/session). Primary (body weight) and secondary outcomes (waist circumference, energy/macronutrient intake, physical activity) will be assessed at baseline, 6, 12, 18 and 24 mos. Cost and contingent valuation analyses will also be completed. NCT REGISTRATION: NCT02932748.

AB - The effect of hibernation on oxidative stress and antioxidant defense was assessed in the frog Nanorana parkeri which inhabits the southern Tibetan Plateau. We compared the indices of oxidative stress (GSSG/GSH), the degree of oxidative damage (content of carbonyl proteins and lipid peroxide products) and the activities of antioxidant enzymes (SOD, CAT, GPx, GST and GR) in liver, brain, heart and muscle of N. parkeri sampled during summer and winter. Obtained results showed that hibernation induced a significant decrease in the level of GSH in heart, liver, and muscle, while the ratio of GSSG/GSH markedly increased in all tissues except for muscle. Regarding oxidative damage, significant increases in TBARS were observed in all tissues of N. parkeri in the midst of hibernation, and the lipid peroxides level also clearly elevated in these tissues except the liver. In liver and brain, the level of carbonyl proteins was significantly higher in winter relative to summer. Additionally, the activity of antioxidant enzymes obviously reduced in the liver of hibernating N. parkeri. The total antioxidant capacity was also significantly lower in all tissues during winter than summer. In conclusion, hibernation in N. parkeri induced oxidative stress which was supported by oxidative damage to lipids and proteins with suppression of antioxidant defense. PMID- 29454143 TI - The osmorespiratory compromise in rainbow trout (Oncorhynchus mykiss): The effects of fish size, hypoxia, temperature and strenuous exercise on gill diffusive water fluxes and sodium net loss rates. AB - In the context of the osmorespiratory compromise, hypoxia and temperature have been little studied relative to exercise, and diffusive water flux rates (as assessed by 3H2O efflux) have received almost no attention. We investigated the effects of fish size, hypoxia, exercise and acute temperature increase on diffusive water flux rates and net sodium loss rates in juvenile rainbow trout. Trout weighing 13-50 g were used to determine the effects of fish size under normoxia. Thereafter 25-50 g trout were selected to assess the effects of different hypoxia levels (3.15, 5.25 and 8.40 KPa), time course of hypoxia (1 h 8.40 KPa, 3 h 8.40 KPa, 1 h 8.40 KPa +1 h normoxic recovery, and 1 h 8.40 KPa + 3 h normoxic recovery), strenuous exercise (5 min) and acute temperature challenge (transfer from 8 degrees C to 13 degrees C or to 18 degrees C). Small fish (13 g) had higher diffusive water flux rates than larger fish, turning over >100% of their fractional body water pool per hour against 34% per hour for 50 g fish. Hypoxic exposure exerted a biphasic effect, increasing the diffusive water flux rate at 8.40 KPa and 5.25 KPa, while returning it to control levels at 3.15 KPa. All the levels of hypoxia increased net Na+ loss. One hour hypoxia (8.40 KPa) increased diffusive water flux rate while prolonged 3 h hypoxia (8.40 KPa), and short or prolonged normoxic recovery returned diffusive water flux rates to control levels. All the treatments over the time course of hypoxia and normoxic recovery increased net Na+ loss rates. Strenuous exercise increased both the diffusive water flux and net Na+ loss rates. Acute temperature rise increased diffusive water flux rates, with Q10 values of 4.03 for 8 to 13 degrees C and 2.16 for 8 to 18 degrees C, but the net Na+ loss rate did not change. There was no significant correlation between diffusive water flux rate and net Na+ loss rates at different hypoxia levels, over the course of hypoxia and normoxic recovery, or during acute temperature stress. In contrast, we observed a significant correlation between diffusive water flux and net Na+ loss rates following exercise. Overall, diffusive water flux and sodium loss were regulated differently during acute temperature challenge and hypoxia, while following exercise the two parameters were regulated in a similar fashion. PMID- 29454144 TI - Natural Orifice Specimen Extraction during Laparoscopic Bowel Resection for Colorectal Endometriosis: Technique and Outcome. AB - STUDY OBJECTIVE: To present a detailed description of a modified natural orifice specimen extraction (NOSE) colectomy technique. We also report the postoperative outcomes of our prospective case series when compared with conventional laparoscopic bowel resection in a relatively large series of patients. DESIGN: Canadian Task Force classification II-1. SETTING: A university tertiary referral center. PATIENTS: The last 90 consecutive patients in our care with deep infiltrating endometriosis of the bowel are presented in this study. Patients were diagnosed at the 1st Department of Obstetrics and Gynecology, Semmelweis University, Budapest, Hungary. INTERVENTIONS: We performed laparoscopic bowel resection using the transrectal NOSE technique and compared the results of the new operative method (n = 30) with traditional laparoscopic bowel resection (n = 60). MEASUREMENTS AND MAIN RESULTS: The median duration of surgery was 121 minutes in the control group and 96 minutes in the NOSE group (p = .005). According to the Clavien-Dindo classification, we observed a severe, grade IIIb or higher, overall complication rate of 3.3% among all 90 patients. In the control group, anastomosis insufficiency occurred in 3.3% of patients (2/60 cases), and in 1 patient with anastomotic leakage a rectovaginal fistula was observed (1.7%). There was no significant difference in the rates of severe postoperative complications (p = .55). The length of hospital stay in the control group was a median of 7 days (range, 5-13 days), whereas in the NOSE group it was 6 days (range, 3-11 days) (p < .001). CONCLUSION: According to our findings, the use of NOSE colectomy offers a shorter recovery time and can eventually lead to a shorter surgery duration compared with traditional laparoscopic bowel resection.

PMID- 29454146 TI - Matching Trends for the Fellowship in Minimally Invasive Gynecologic Surgery Since Participation in the National Residency Match Program. AB - OBJECTIVE: To evaluate the level of interest in the fellowship in minimally invasive gynecologic surgery (FMIGS) using data from the National Residency Match Program (NRMP) over the past 5 years. DESIGN: Retrospective report (Canadian Task Force classification II-2). SETTING: Publicly reported data from the NRMP. PARTICIPANTS: Applicants using the NRMP to match into fellowship training. INTERVENTIONS: Reporting matching trends for the gynecologic surgical subspecialty programs starting in 2014, when the FMIGS programs began participating in the NRMP. MEASUREMENTS AND MAIN RESULTS: From 2014 to 2018, the number of FMIGS positions increased from 28 to 38. Over the 5 application cycles, the FMIGS programs had the highest ratio of applicants to positions overall (range, 1.7-2.0 for FMIGS) of the surgical gynecologic subspecialty programs analyzed (Gynecologic Oncology, Female Pelvic Medicine and Reconstructive Surgery, and Reproductive Endocrinology and Infertility). CONCLUSIONS: Since the FMIGS programs began participating in the NRMP in 2014, the FMIGS match has been highly competitive as a gynecologic surgical subspecialty, suggesting a high level of interest from residency graduates. This may reflect growing recognition that there is a body of knowledge unique to minimally invasive gynecologic surgeons. PMID- 29454147 TI - Factors Associated with Malignancy in Hysteroscopically Resected Endometrial Polyps: A Systematic Review and Meta-Analysis. AB - In this study, we aimed to estimate the frequency of premalignant and malignant lesions in endometrial polyps, and to evaluate associated clinical and demographic factors. A literature search was performed in major databases and the gray literature using the terms polyps OR endometrial polyp AND endometrial neoplasms OR endometrial cancer OR endometrial hyperplasia OR malignan*. Studies describing the frequency of premalignant and malignant lesions in endometrial polyps and any clinical or demographic factors associated with malignant lesions extracted using hysteroscopy were considered eligible. Independent investigators selected the studies and extracted the data. A meta-analysis was performed using a random-effects model and meta-regression. We identified 37 studies (comprising 21,057 patients) of endometrial polyps. The prevalence of premalignant and malignant lesions was 3.4% (95% confidence interval [CI], 2.8-4.1; I2, 80.5%). Abnormal uterine bleeding (prevalence ratio [PR], 1.47; 95% CI, 1.27-1.69; I2, 82.4%), menopausal status (PR, 1.67; 95% CI, 1.48-1.89; I2, 78.4%), age >60 years (PR, 2.41; 95% CI, 1.84-3.16; I2, 81.5%), diabetes mellitus (PR, 1.76; 95% CI, 1.43-2.16; I2, 0.0%), systemic arterial hypertension (PR, 1.50; 95% CI, 1.20 1.88; I2, 75.9%), obesity (PR, 1.41; 95% CI:1.13-1.76; I2, 41.2%), and tamoxifen use (PR, 1.53; 95% CI, 1.06-2.21; I2, 0.0%) were associated with endometrial polyp malignancy. However, breast cancer (PR, 0.83; 95% CI, 0.44-1.57; I2, 0.0%), hormonal therapy (PR, 0.93; 95% CI, 0.67-1.30; I2, 31.7%), parity (PR, 0.87; 95% CI, 0.39-1.96; I2, 78.1%), and endometrial polyp size (PR, 1.05; 95% CI, 0.70 1.57; I2, 44.7%) were not associated with malignancy of endometrial polyps. Three of every 100 women with clinically recognized polyps, a condition associated with specific clinical and demographic factors, will harbor premalignant or malignant lesions. PMID- 29454148 TI - 68Ga[Ga]-Galmydar: Biodistribution and radiation dosimetry studies in rodents. AB - INTRODUCTION: 68Ga[Ga]-Galmydar is an avid transport substrate of ABCB1 (P Glycoprotein; 170kDa plasma membrane protein), breast cancer resistance protein (BCRP; ABCG2; 72kDa), penetrates human epidermal carcinoma (KB3-1), breast cancer (MCF7), embryonic kidney (HEK 293) tumor cells and rat cardiomyoblasts, and localizes within the mitochondria of tumor and myocardium cells. 68Ga[Ga] Galmydar excretes from blood pool quickly, and shows stable retention within rat myocardium in vivo for extended periods, therefore, the agent shows potential to enable myocardial perfusion imaging. The PET tracer also demonstrates ability to probe viability of the blood brain barrier (BBB) in WT mice compared with their mdr1a/1b(-/-) (dKO) and mdr1a/1b/ABCG2(-/-/-) (t-KO) counterparts. Herein, we report dosimetry data for 68Ga[Ga]-Galmydar in mice, and extrapolate that information to determine effective dose (ED) for human studies. METHODS: To further assess safety profiles of 68Ga[Ga]-Galmydar for enabling its deployment as a PET imaging probe for biomedical imaging in vivo, we estimated human radiation dosimetry extrapolated from mice biodistribution data. To accomplish this objective, 68Ga[Ga]-Galmydar was injected intravenously into tails, mice were euthanized, organs harvested (5min, 15min, 30min, 60min, 120min), counted, radiation doses to each organ, and whole body were also determined. RESULTS: The effective dose (ED) have been found to be 0.021mGy/MBq in males and 0.023mGy/MBq in females. The highest radiation dose was estimated to the kidneys with a value of 0.17mGy/MBq for males and 0.19mGy/MBq for females with contribution from activity in the urine prior to excretion. The critical organ in humans has been determined to be the gall bladder. These data provide preliminary projections on human dosimetry derived from rodent estimates thus providing platform for further validation of dosimetry analysis in human subjects. CONCLUSIONS: Combined data obtained from radiation dosimetry studies in mice indicate that 68Ga[Ga]-Galmydar would be safe for further evaluation of dosimetry toxicity and myocardial perfusion PET imaging in humans. PMID- 29454149 TI - Study of manganese binding to the ferroxidase centre of human H-type ferritin. AB - Ferritins are ubiquitous and conserved proteins endowed with enzymatic ferroxidase activity, that oxidize Fe(II) ions at the dimetal ferroxidase centre to form a mineralized Fe(III) oxide core deposited within the apo-protein shell. Herein, the in vitro formation of a heterodimetal cofactor constituted by Fe and Mn ions has been investigated in human H ferritin (hHFt). Namely, Mn and Fe binding at the hHFt ferroxidase centre and its effects on Fe(II) oxidation have been investigated by UV-Vis ferroxidation kinetics, fluorimetric titrations, multifrequency EPR, and preliminary Mossbauer spectroscopy. Our results show that in hHFt, both Fe(II) and Mn(II) bind the ferroxidase centre forming a Fe-Mn cofactor. Moreover, molecular oxygen seems to favour Mn(II) binding and increases the ferroxidation activity of the Mn-loaded protein. The data suggest that Mn influences the Fe binding and the efficiency of the ferroxidation reaction. The higher efficiency of the Mn-Fe heterometallic centre may have a physiological relevance in specific cell types (i.e. glia cells), where the concentration of Mn is the same order of magnitude as iron. PMID- 29454150 TI - Assessment of cervical stiffness in axial rotation among chronic neck pain patients: A trial in the framework of a non-manipulative osteopathic management. AB - BACKGROUND: Cervical stiffness is a clinical feature commonly appraised during the functional examination of cervical spine. Measurements of cervical stiffness in axial rotation have not been reported for patients with neck pain. The purpose of this study was to investigate cervical spine stiffness in axial rotation among neck pain patients and asymptomatic subjects, and to analyze the impact of osteopathic management. METHODS: Thirty-five individuals (17 patients) were enrolled. Measurements were carried out for left-right axial rotation using a torque meter device, prior and after intervention. Passive range of motion, stiffness, and elastic-and neutral zone magnitudes were analyzed. Pain intensity was also collected for patients. The intervention consisted in one single session of non-manipulative osteopathic treatment performed in both groups. FINDINGS: A significant main effect of intervention was found for total range of motion and neutral zone. Also, treatment by group interaction was demonstrated for neutral-, elastic zone, stiffness in right axial rotation, and for total neutral zone. Significant changes were observed in the clinical group after intervention, indicating elastic zone decrease and neutral zone increase. In contrast, no significant alteration was detected for the control group. INTERPRETATIONS: Stiffness characteristics of the cervical spine in axial rotation are prone to be altered in patients with neck pain, but seem to be relieved after a session of non-manipulative manual therapeutic techniques. Further investigations, including randomized clinical trials with various clinical populations and therapeutic modalities, are needed to confirm these preliminary findings. PMID- 29454151 TI - Humoral response to John Cunningham virus during pregnancy in multiple sclerosis. AB - BACKGROUND: Pregnancy induces an immunosuppressive state in the mother to ensure immunological acceptance of the foetus. Impairment of cell-mediated immune responses may render the mother susceptible to intracellular pathogens. It is not presently known whether pregnancy alters the immunosurveillance for John Cunningham virus (JCV), an opportunistic pathogen associated with natalizumab treatment for multiple sclerosis (MS). OBJECTIVE: To evaluate whether the humoral immune response to JCV is altered during pregnancy among MS patients and healthy controls to get insight to potential pregnancy-induced alterations related to immune response to JCV during pregnancy. METHODS: Serum anti-JCV-antibody-indices (JCV-Ab-index) were determined by a two-step second-generation enzyme-linked immunosorbent assay in 49 MS patients during and after pregnancy and in 49 healthy controls during pregnancy. For comparison, total IgG levels and antibodies against Epstein-Barr, cytomegalo and measles viruses were similarly measured. RESULTS: The JCV-Ab-indices of MS patients were not altered during the pregnancy (1st vs. 3rd trimester, 0.62 vs. 0.77, p = 0.99). Contrary to this, in the healthy controls JCV-Ab-indices (p = 0.005), antibody levels to the other viruses, and total IgG levels (p < 0.0001) decreased significantly during pregnancy. CONCLUSIONS: JCV-Ab levels remain unaltered during MS pregnancy, while the total IgG concentration is reduced/diluted due to increasing plasma volumes during the course of pregnancy. This may imply a biologically significant alteration in the immune response to JCV during MS pregnancy. PMID- 29454152 TI - The influence of biogenic amines on Th17-mediated immune response in multiple sclerosis. AB - Biogenic amines are direct mediators of interactions between immune and nervous systems implicated in the pathogenesis of multiple sclerosis (MS). Recently, great attention has been drawn to studying the effects of biogenic amines on Th17 cells, which play one of the central roles in the development of inflammatory lesions in MS. Results of these studies suggest that, depending on the activation of particular receptors, biogenic amines can both enhance and inhibit Th17-cell functions. Based on these data, targeting biogenic amines and their receptors could be explored as a new kind of additional disease-modifying treatment of MS. PMID- 29454153 TI - Muscle carnosine in experimental autoimmune encephalomyelitis and multiple sclerosis. AB - BACKGROUND: Muscle carnosine is related to contractile function (Ca++ handling) and buffering of exercise-induced acidosis. As these muscular functions are altered in Multiple Sclerosis (MS) it is relevant to understand muscle carnosine levels in MS. METHODS: Tibialis anterior muscle carnosine was measured in an animal MS model (EAE, experimental autoimmune encephalomyelitis, n = 40) and controls (CON, n = 40) before and after exercise training (EAEEX, CONEX, 10d, 1 h/d, 24 m/min treadmill running) or sedentary conditions (EAESED, CONSED). Human m. vastus lateralis carnosine of healthy controls (HC, n = 22) and MS patients (n = 24) was measured. RESULTS: EAE muscle carnosine levels were decreased (p < .0001) by ~ 40% to ~ 64% at 10d and 17d following EAE induction (respectively) regardless of exercise (p = .823). Similarly, human MS muscle carnosine levels were decreased (- 25%, p = .03). CONCLUSION: Muscle carnosine concentrations in an animal MS model and MS patients are substantially reduced. In EAE exercise therapy does not restore this. PMID- 29454154 TI - Age-related functional changes in domain-specific medial temporal lobe pathways. AB - There is now converging evidence from studies in animals and humans that the medial temporal lobes (MTLs) harbor anatomically distinct processing pathways for object and scene information. Recent functional magnetic resonance imaging studies in humans suggest that this domain-specific organization may be associated with a functional preference of the anterior-lateral part of the entorhinal cortex (alErC) for objects and the posterior-medial entorhinal cortex (pmErC) for scenes. As MTL subregions are differentially affected by aging and neurodegenerative diseases, the question was raised whether aging may affect the 2 pathways differentially. To address this possibility, we developed a paradigm that allows the investigation of object memory and scene memory in a mnemonic discrimination task. A group of young (n = 43) and healthy older subjects (n = 44) underwent functional magnetic resonance imaging recordings during this novel task, while they were asked to discriminate exact repetitions of object and scene stimuli from novel stimuli that were similar but modified versions of the original stimuli ("lures"). We used structural magnetic resonance images to manually segment anatomical components of the MTL including alErC and pmErC and used these segmented regions to analyze domain specificity of functional activity. Across the entire sample, object processing was associated with activation of the perirhinal cortex (PrC) and alErC, whereas for scene processing, activation was more predominant in the parahippocampal cortex and pmErC. Functional activity related to mnemonic discrimination of object and scene lures from exact repetitions was found to overlap between processing pathways and suggests that while the PrC-alErC pathway was more involved in object discrimination, both pathways were involved in the discrimination of similar scenes. Older adults were behaviorally less accurate than young adults in discriminating similar lures from exact repetitions, but this reduction was equivalent in both domains. However, this was accompanied by significantly reduced domain-specific activity in PrC in older adults compared to what was observed in the young. Furthermore, this reduced domain-specific activity was associated to worse performance in object mnemonic discrimination in older adults. Taken together, we show the fine-grained functional organization of the MTL into domain-specific pathways for objects and scenes and their mnemonic discrimination and further provide evidence that aging might affect these pathways in a differential fashion. Future experiments will elucidate whether the 2 pathways are differentially affected in early stages of Alzheimer's disease in relation to amyloid or tau pathology. PMID- 29454155 TI - Immune checkpoint inhibitors in non-small cell lung cancer (NSCLC): Approaches on special subgroups and unresolved burning questions. AB - Immune checkpoint inhibitors (ICIs) have been incorporated in the treatment strategy of advanced non-small cell lung cancer (NSCLC). Beyond the already approved indications in first- and second-line setting of advanced NSCLC, new data has recently emerged demonstrating its efficacy in locally advanced disease as maintenance after chemo-radiotherapy and currently several trials are also exploring its efficacy in earlier stages of the disease to evaluate whether these results could be extrapolated to the adjuvant setting. With the advent of all these new therapies, their potential in other thoracic malignancies such as mesothelioma and small-cell lung cancer are also being evaluated with encouraging preliminary data that endorses their short-term incorporation as new therapeutic options in these thoracic malignancies. However, despite all these new evidence, there are still several open questions that remain to be solved like the use of immune agents in special subpopulations such as elderly or fragile patients or the case of patients with brain metastases or autoimmune disorders. In addition some other open questions remain with regards ICIs activity in patients receiving corticosteroid or antibiotics, the potential use in oncogenic addicted tumours, as well as the safety of retreatment after the onset of immune-related adverse events (ir-AE) or the optimal dose schedule or time on treatment for ICIs administration. Herein, we propose to address all these questions, reviewing most recent evidence available in order to give readers some practical advises and guidance on how to deal with these challenges when treating NSCLC patients with immunotherapy. PMID- 29454156 TI - The GluN2B subunit represents a major functional determinant of NMDA receptors in human induced pluripotent stem cell-derived cortical neurons. AB - Abnormal signaling pathways mediated by N-methyl-d-aspartate receptors (NMDARs) have been implicated in the pathogenesis of various CNS disorders and have been long considered as promising points of therapeutic intervention. However, few efforts have been previously described concerning evaluation of therapeutic modulators of NMDARs and their downstream pathways in human neurons with endogenous expression of NMDARs. In the present study, we assessed expression, functionality, and subunit composition of endogenous NMDARs in human induced pluripotent stem cell (hiPSC)-derived cortical neurons (iCell Neurons and iCell GlutaNeurons). We initially confirmed the expected pharmacological response of iCell Neurons and iCell GlutaNeurons to NMDA by patch-clamp recordings. Subsequent pharmacological interrogation using GluN2 subunit-selective antagonists revealed the predominance of GluN2B in both iCell Neurons and iCell GlutaNeurons. This observation was also supported by qRT-PCR and Western blot analyses of GluN2 subunit expression as well as pharmacological experiments using positive allosteric modulators with distinct GluN2 subunit selectivity. We conclude that iCell Neurons and iCell GlutaNeurons express functional GluN2B containing NMDARs and could serve as a valuable system for development and validation of GluN2B-modulating pharmaceutical agents. PMID- 29454157 TI - Nanofibrous PLGA electrospun scaffolds modified with type I collagen influence hepatocyte function and support viability in vitro. AB - : A major challenge of maintaining primary hepatocytes in vitro is progressive loss of hepatocyte-specific functions, such as protein synthesis and cytochrome P450 (CYP450) catalytic activity. We developed a three-dimensional (3D) nanofibrous scaffold made from poly(l-lactide-co-glycolide) (PLGA) polymer using a newly optimized wet electrospinning technique that resulted in a highly porous structure that accommodated inclusion of primary human hepatocytes. Extracellular matrix (ECM) proteins (type I collagen or fibronectin) at varying concentrations were chemically linked to electrospun PLGA using amine coupling to develop an in vitro culture system containing the minimal essential ECM components of the liver micro-environment that preserve hepatocyte function in vitro. Cell-laden nanofiber scaffolds were tested in vitro to maintain hepatocyte function over a two-week period. Incorporation of type I collagen onto PLGA scaffolds (PLGA Chigh: 100 ug/mL) led to 10-fold greater albumin secretion, 4-fold higher urea synthesis, and elevated transcription of hepatocyte-specific CYP450 genes (CYP3A4, 3.5-fold increase and CYP2C9, 3-fold increase) in primary human hepatocytes compared to the same cells grown within unmodified PLGA scaffolds over two weeks. These indices, measured using collagen-bonded scaffolds, were also higher than scaffolds coupled to fibronectin or an ECM control sandwich culture composed of type I collagen and Matrigel. Induction of CYP2C9 activity was also higher in these same type I collagen PLGA scaffolds compared to other ECM-modified or unmodified PLGA constructs and was equivalent to the ECM control at 7 days. Together, we demonstrate a minimalist ECM-based 3D synthetic scaffold that accommodates primary human hepatocyte inclusion into the matrix, maintains long-term in vitro survival and stimulates function, which can be attributed to coupling of type I collagen. STATEMENT OF SIGNIFICANCE: Culturing primary hepatocytes within a three-dimensional (3D) structure that mimics the natural liver environment is a promising strategy for extending the function and viability of hepatocytes in vitro. In the present study we generate porous PLGA nanofibers, that are chemically modified with extracellular matrix proteins, to serve as 3D scaffolds for the in vitro culture of primary human hepatocytes. Our findings demonstrate that the use of ECM proteins, especially type I collagen, in a porous 3D environment helps to improve the synthetic function of primary hepatocytes over time. We believe the work presented within will provide insights to readers for drug toxicity and tissue engineering applications. PMID- 29454158 TI - Polyisocyanopeptide hydrogels: A novel thermo-responsive hydrogel supporting pre vascularization and the development of organotypic structures. AB - : Molecular and mechanical interactions with the 3D extracellular matrix are essential for cell functions such as survival, proliferation, migration, and differentiation. Thermo-responsive biomimetic polyisocyanopeptide (PIC) hydrogels are promising new candidates for 3D cell, tissue, and organ cultures. This is a synthetic, thermo-responsive and stress-stiffening material synthesized via polymerization of the corresponding monomers using a nickel perchlorate as a catalyst. It can be tailored to meet various demands of cells by modulating its stiffness and through the decoration of the polymer with short GRGDS peptides using copper free click chemistry. These peptides make the hydrogels biocompatible by mimicking the binding sites of certain integrins. This study focuses on the optimization of the PIC polymer properties for efficient cell, tissue and organ development. Screening for the optimal stiffness of the hydrogel and the ideal concentration of the GRGDS ligand conjugated with the polymer, enabled cell proliferation, migration and differentiation of various primary cell types of human origin. We demonstrate that fibroblasts, endothelial cells, adipose-derived stem cells and melanoma cells, do survive, thrive and differentiate in optimized PIC hydrogels. Importantly, these hydrogels support the spontaneous formation of complex structures like blood capillaries in vitro. Additionally, we utilized the thermo-responsive properties of the hydrogels for a rapid and gentle recovery of viable cells. Finally, we show that organotypic structures of human origin grown in PIC hydrogels can be successfully transplanted subcutaneously onto immune-compromised rats, on which they survive and integrate into the surrounding tissue. STATEMENT OF SIGNIFICANCE: Molecular and mechanical interactions with the surrounding environment are essential for cell functions. Although 2D culture systems greatly contributed to our understanding of complex biological phenomena, they cannot substitute for crucial interaction that take place in 3D. 3D culture systems aim to overcome limitations of the 2D cultures and answer new questions about cell functions. Thermo responsive biomimetic polyisocyanopeptide (PIC) hydrogels are promising new candidates for 3D cell, tissue, and organ cultures. They are synthetic and can be tailor to meet certain experimental demands. Additionally, they are characterized by strain-stiffening, a feature crucial for cell behaviour, but rare in hydrogels. Their thermos-responsive properties enable quick recovery of the cells by a simple procedure of lowering the temperature. PMID- 29454159 TI - An aligned porous electrospun fibrous membrane with controlled drug delivery - An efficient strategy to accelerate diabetic wound healing with improved angiogenesis. AB - : A chronic wound in diabetic patients is usually characterized by poor angiogenesis and delayed wound closure. The exploration of efficient strategy to significantly improve angiogenesis in the diabetic wound bed and thereby accelerate wound healing is still a significant challenge. Herein, we reported a kind of aligned porous poly (l-lactic acid) (PlLA) electrospun fibrous membranes containing dimethyloxalylglycine (DMOG)-loaded mesoporous silica nanoparticles (DS) for diabetic wound healing. The PlLA electrospun fibers aligned in a single direction and there were ellipse-shaped nano-pores in situ generated onto the surface of fibers, while the DS were well distributed in the fibers and the DMOG as well as Si ion could be controlled released from the nanopores on the fibers. The in vitro results revealed that the aligned porous composite membranes (DS-PL) could stimulate the proliferation, migration and angiogenesis-related gene expression of human umbilical vein endothelial cells (HUVECs) compared with the pure PlLA membranes. The in vivo study further demonstrated that the prepared DS PL membranes significantly improved neo-vascularization, re-epithelialization and collagen formation as well as inhibited inflammatory reaction in the diabetic wound bed, which eventually stimulated the healing of the diabetic wound. Collectively, these results suggest that the combination of hierarchical structures (nanopores on the aligned fibers) with the controllable released DMOG drugs as well as Si ions from the membranes, which could create a synergetic effect on the rapid stimulation of angiogenesis in the diabetic wound bed, is a potential novel therapeutic strategy for highly efficient diabetic wound healing. STATEMENT OF SIGNIFICANCE: A chronic wound in diabetic patients is usually characterized by the poor angiogenesis and the delayed wound closure. The main innovation of this study is to design a new kind of skin tissue engineered scaffold, aligned porous poly (l-lactic acid) (PlLA) electrospun membranes containing dimethyloxalylglycine (DMOG)-loaded mesoporous silica nanoparticles (DS), which could significantly improve angiogenesis in the diabetic wound bed and thereby accelerate diabetic wound healing. The results revealed that the electrospun fibers with ellipse-shaped nano-pores on the surface were aligned in a single direction, while there were DS particles distributed in the fibers and the DMOG as well as Si ions could be controllably released from the nanopores on the fibers. The in vitro studies demonstrated that the hierarchical nanostructures (nanopores on the aligned fibers) and the controllable released chemical active agents (DMOG drugs and Si ions) from the DS-PL membranes could exert a synergistic effect on inducing the endothelial cell proliferation, migration and differentiation. Above all, the scaffolds distinctly induced the angiogenesis, collagen deposition and re-epithelialization as well as inhibited inflammation reaction in the wound sites, which eventually stimulated the healing of diabetic wounds in vivo. The significance of the current study is that the combination of the hierarchical aligned porous nanofibrous structure with DMOG loaded MSNs incorporated in electrospun fibers may suggest a high-efficiency strategy for chronic wound healing.

AB - How fish respond to hypoxia, a common stressor, can be altered by simultaneous exposure to pollutants like bisphenol A (BPA), a plasticizer. BPA is cardiotoxic and interferes with the hypoxia inducible factor pathway (HIF-1alpha), therefore disrupting the hypoxic response. Co-exposure to hypoxia and BPA also causes severe bradycardia and reduced cardiac output in zebrafish larvae. The purpose of this work was to determine how the cardiovascular effects of co-exposure vary with BPA concentration and persist beyond exposure. Zebrafish embryos were exposed to 0, 0.01, 0.1, 1, and 100 MUg/L of BPA during normoxia (>6.0 mg/L O2) and hypoxia (2.0 +/- 0.5 mg/L O2) between 1 h post fertilization (hpf) and late hatching (72-96 hpf). Heart rate, cardiac output, and red blood cell (RBC) velocity were determined through video microscopy and digital motion analysis at late hatching and 10 days post fertilization (dpf), several days post exposure. In comparison to the hypoxic control, RBC velocity was 25% lower with 0.01 MUg/L BPA and hypoxia at late hatching. At 10 dpf, the difference in RBC velocity between these treatments doubled, despite several days of recovery. This coincided with a 24% thinner outer diameter for caudal vein but no effect on cardiac or developmental parameters. Statistical interactions between BPA and oxygen concentration were found for arterial RBC velocity at both ages. Because the co-occurrence of both stressors is extremely common, it would be beneficial to understand how BPA and hypoxia interact to affect cardiovascular function during and after exposure.

AB - Previous studies have reported a preponderance of autoimmune thyroiditis (AIT) in females, but the detailed mechanisms have not been elucidated. In this study, we explored the effects of oestrogen on experimental AIT (EAT) and its potential mechanisms in an ovariectomised mouse model through the supplementation of high (equivalent to the level during pregnancy) or low (equivalent to the level at the oestrus stage) doses of oestradiol (E2). We found that EAT incidence, the intrathyroidal inflammatory score, serum anti-thyroglobulin IgG2b levels, splenic mRNA expression of Th1- and Th17-specific transcription factors and typical cytokines and the proportion of IL-12-producing dendritic cells were significantly increased in EAT mice treated with low-dose E2 compared with those in the control group. However, they were not changed when administered with high dose E2. These findings indicate that low physiological levels of E2 can stimulate the occurrence and development of EAT through the up-regulation of Th1/Th17 responses. PMID- 29454163 TI - Exacerbations in Adults with Asthma: A Systematic Review and External Validation of Prediction Models. AB - BACKGROUND: Several prediction models assessing future risk of exacerbations in adult patients with asthma have been published. Applicability of these models is uncertain because their predictive performance has often not been assessed beyond the population in which they were derived. OBJECTIVE: This study aimed to identify and critically appraise prediction models for asthma exacerbations and validate them in 2 clinically distinct populations. METHODS: PubMed and EMBASE were searched to April 2017 for reports describing adult asthma populations in which multivariable models were constructed to predict exacerbations during any time frame. After critical appraisal, the models' predictive performances were assessed in a primary and a secondary care population for author-defined exacerbations and for American Thoracic Society/European Respiratory Society defined severe exacerbations. RESULTS: We found 12 reports from which 24 prediction models were evaluated. Three predictors (previous health care utilization, symptoms, and spirometry values) were retained in most models. Assessment was hampered by suboptimal methodology and reporting, and by differences in exacerbation outcomes. Discrimination (area under the receiver operating characteristic curve [c-statistic]) of models for author-defined exacerbations was better in the primary care population (mean, 0.71) than in the secondary care population (mean, 0.60) and similar (0.65 and 0.62, respectively) for American Thoracic Society/European Respiratory Society-defined severe exacerbations. Model calibration was generally poor, but consistent between the 2 populations. CONCLUSIONS: The preservation of 3 predictors in models derived from variable populations and the fairly consistent predictive properties of most models in 2 distinct validation populations suggest the feasibility of a generalizable model predicting severe exacerbations. Nevertheless, improvement of the models is warranted because predictive performances are below the desired level.

AB - BACKGROUND: Studies have reliably identified an association between suicide attempts and executive functions such as decision making (DM) and inhibitory control (IC) in patients with mood disorders. As such, the present study aimed to investigate the association between inhibition, DM, impulsivity and the history of suicide attempts in individuals with bipolar (BD) or major depressive disorder (MDD), identifying which assessment instruments may be most strongly associated with suicide in clinical samples. METHODS: The sample included 80 control subjects and two groups of patients with BD and MDD, matched by age and education (26 with a history of suicide attempts [MD+], and 26 with no such history [MD-]). Participants completed behavioral and self-report measures of DM and IC, which were compared between groups using ANCOVA, followed by logistic regression for patients with mood disorders only, and the presence or absence of a history of suicide as the outcome. RESULTS: Cognitive performance did not differ between groups. The MD+ group showed significantly higher motor and attentional impulsivity on the BIS-11 than the MD- and control groups. A regression analysis containing these scores showed that motor impulsivity was the only significant predictor of a history of suicide (OR = 1.14; 95%CI 1.00-1.30). CONCLUSIONS: Self reported motor impulsivity was a significant predictor of suicide. These findings underscore the importance of self-report measures in neuropsychological assessment, and their contributions to the management and prognosis of patients with mood disorders. Lastly, they point to the role of impulsivity as a target for interventions and public policy on suicide prevention. PMID- 29454165 TI - Pituitary gland shrinkage in bipolar disorder: The role of gender. AB - BACKGROUND: Hyperactivity of the Hypothalamic-Pituitary-Adrenal Axis (HPAA) has been consistently reported in mood disorders. However, only few studies investigated the Pituitary gland (PG) in Bipolar Disorder (BD) and the results are so far contrasting. Therefore, the aim of this study is to explore the integrity of the PG as well as the role of gender and the impact of clinical measurements on this structure in a sample of BD patients compared to healthy controls (HC). METHODS: 34 BD patients and 41 HC underwent a 1.5 T MRI scan. PG volumes were manually traced for all subjects. Psychiatric symptoms were assessed by means of the Brief Psychiatry Rating Scale, the Hamilton Depression Rating Scale and the Bech Rafaelsen Mania Rating Scale. RESULTS: We found decreased PG volumes in BD patients compared to HC (F = 24.9, p < 0.001). Interestingly, after dividing the sample by gender, a significant PG volume decrease was detected only in female BD patients compared to female HC (F = 9.1, p < 0.001), but not in male BD compared to male HC (F = -0.12, p = 0.074). No significant correlations were observed between PG volumes and clinical variables. CONCLUSIONS: Our findings suggest that BD patients have decreased PG volumes, probably due to the long-term hyperactivity of the HPAA and to the consequent strengthening of the negative feedback control towards the PG volume itself. This alteration was particularly evident in females, suggesting a role of gender in affecting PG volumes in BD. Finally, the absence of significant correlations between PG volumes and clinical variables further supports that PG disruption is a trait feature of BD, being independent of symptoms severity and duration of treatment. PMID- 29454166 TI - A water-based topical Chinese traditional medicine (Zicao) for wound healing developed using 2-hydroxypropyl-beta-cyclodextrin. AB - Zicao is a traditional Chinese herbal medicine that has been used for the topical treatment of wounds in the form of oil-based ointment for several hundred years. To overcome the disadvantages of oil-based ointment such as irritation, discomfort, and difficulty in cleaning, this study developed a water-based topical formulation of Zicao. An ethanol extract of Zicao was included in 2 hydroxypropyl-beta-cyclodextrin (HP-beta-CD) to form a water-soluble Zicao-HP beta-CD complex. The formation of the Zicao-HP-beta-CD complex was determined using LC-MS, 1H NMR, ROSEY, and solubility analysis. The bioactivity of Zicao-HP beta-CD complex in aqueous solution was evaluated using cellular uptake in vitro and experimental excision wounds in vivo. The LC-MS, 1H NMR, ROESY, and solubility analyses results show that Zicao extract was successfully included by the HP-beta-CD. The results of the cellular uptake in vitro and wound healing in vivo suggest that the effect of Zicao was enhanced following the formation of the Zicao-HP-beta-CD complex. Therefore, we concluded that complexation with HP-beta CD might provide a potential method for developing an effective water-based topical solution of Zicao. PMID- 29454162 TI - Anxiety, Depression, and Asthma Control: Changes After Standardized Treatment. AB - BACKGROUND: It has been documented that anxiety and depression are prevalent in patients with asthma and are associated with greater frequency of exacerbations, increased use of health care resources, and poor asthma control. OBJECTIVE: To examine the association of asthma diagnosis with symptoms of depression/anxiety and asthma control not only at baseline but also over a 6-month period of specialist supervision. METHODS: We enrolled 3182 patients with moderate to severe asthma. All were evaluated with spirometry, the Asthma Control Test, and the Hospital Anxiety and Depression Scale at baseline and at 6 months. Treatments were decided by specialists according to published guidelines. RESULTS: At baseline, 24.2% and 12% of the patients were diagnosed with anxiety and depression, respectively, according to the Hospital Anxiety and Depression Scale. After 6 months, anxiety and depression improved, affecting 15.3% and 8.1% of patients, respectively (P < .001); mean FEV1 and asthma control also improved (FEV1 from 81.6% +/- 20.9% to 86% +/- 20.8%; Asthma Control Test score from 15.8 +/- 4.7 to 19.4 +/- 4.4; both P < .001). Patients with anxiety and depression used significantly more health care resources and had more exacerbations. A multivariate analysis showed that patients with anxiety, depression, and lower FEV1 (odds ratio, 0.20, 0.34, 0.62, respectively; P < .001) were independently associated with poor asthma control. A multiple linear regression analysis showed that anxiety had a nearly 4-fold greater influence over asthma control than depression (0.326/0.85 = 4.075). CONCLUSION: Under standardized asthma care and after a specific visit with the specialist, patients present significant improvement in these psychological disorders and exhibit better asthma control and functional parameters. PMID- 29454167 TI - Polydopamine-coated nanocomposites of Angelica gigas Nakai extract and their therapeutic potential for triple-negative breast cancer cells. AB - Polydopamine (PD)-coated nanocomposites (NCs) based on the ethanol extract of Angelica gigas Nakai (AGN EtOH ext) were fabricated and evaluated for breast cancer therapy. AGN NCs were prepared using a modified emulsification-solvent evaporation method and were further incubated in dopamine solution (at pH 8.6) to be covered with the PD layer. PD-AGN NCs with a 213-nm mean diameter, narrow size distribution, and negative zeta potential values were fabricated in this study. Less negative (close to zero) zeta potential value of PD-AGN NCs than that of AGN NCs implied the existence of the PD layer in the outer surface of NCs. The PD layer in PD-AGN NCs was also identified by X-ray photoelectron spectroscopy (XPS) and ultraviolet (UV)/visible absorption analyses. The sustained release of decursin (D) and decursinol angelate (DA), as major active pharmacological components of AGN, was observed in both AGN NCs and PD-AGN NCs. Enhanced cellular binding property of PD-AGN NCs, compared to AGN NCs, in MDA-MB-231 (human breast adenocarcinoma; triple-negative breast cancer) cells was observed. Improved anticancer activities of PD-AGN NCs compared with those of AGN EtOH ext and AGN NCs were also shown in MDA-MB-231 cells. The developed PD-AGN NCs may be used as remarkable platform nanocarriers for efficient breast cancer therapy. PMID- 29454168 TI - Genetic and environmental influences on pubertal hormones in human hair across development. AB - Puberty is a complex biopsychosocial process that can affect an array of psychiatric and medical disorders emerging in adolescence. Although the pubertal process is driven by neuroendocrine changes, few quantitative genetic studies have directly measured puberty-relevant hormones. Hair samples can now be assayed for accumulation of hormones over several months. In contrast to more conventional salivary measures, hair measures are not confounded by diurnal variation or hormonal reactivity. In an ethnically and socioeconomically diverse sample of 1286 child and adolescent twins and multiples from 672 unique families, we estimated genetic and environmental influences on hair concentrations of testosterone, DHEA, and progesterone across the period of 8-18 years of age. On average, male DHEA and testosterone were highly heritable, whereas female DHEA, progesterone, and puberty were largely influenced by environmental components. We identified sex-specific developmental windows of maximal heritability in each hormone. Peak heritability for DHEA occurred at approximately 10 years of age for males and females. Peak heritability for testosterone occurred at age 12.5 and 15.2 years for males and females, respectively. Peak heritability for male progesterone occurred at 11.2 years, while the heritability of female progesterone remained uniformly low. The identification of specific developmental windows when genetic signals for hormones are maximized has critical implications for well-informed models of hormone-behavior associations in childhood and adolescence. PMID- 29454169 TI - Farmyard manure alone and combined with immobilizing amendments reduced cadmium accumulation in wheat and rice grains grown in field irrigated with raw effluents. AB - Cadmium (Cd) stress is a serious concern in agricultural soils worldwide whereas little is known about the impact of farmyard manure (FYM) alone or combined with limestone, lignite and biochar on Cd concentrations in plants. Wheat was grown in Cd-contaminated field amended with control (T1), FYM @ 0.1% (T2), FYM + limestone @ 0.05% each (T3), FYM + lignite @ 0.05% each (T4), FYM + biochar @ 0.05% each (T5) and subsequent rice was grown without additional use of amendments. Soil application of amendments increased straw and grain yield and thousand grain weight being maximum in FYM + limestone treatment. Wheat and rice straw yield increased by 19% and 10% in T3 than control respectively. Photosynthetic pigments increased with the supply of amendments than control. Amendments decreased Cd concentration, total Cd uptake in straw and grains and Cd harvest index of both crops and the maximum reduction in these parameters was recorded with where FYM + limestone (T3). Cd concentration in wheat and rice straw decreased by 78.5% and 65% in T3 than control, respectively. The highest benefit to cost ratio was obtained in FYM + limestone (T3). Ammonium bicarbonate - diethylenetriamine penta acetic acid (AB-DTPA) extractable Cd of the post-harvest soil reduced whereas Cd immobilization index and soil pH increased with the supply of all treatments than control being maximum in T3. The present study revealed that field management with FYM + limestone increased plant yield and reduced Cd concentrations in grains. PMID- 29454170 TI - Enhanced electrokinetic remediation of polluted soils by anolyte pH conditioning. AB - In the treatment of a polluted soil, the pH has a strong impact on the development of different physicochemical processes as precipitation/dissolution, adsorption/desorption or ionic exchange. In addition, the pH determines the chemical speciation of the compounds present in the system and, consequently, it conditions the transport processes by which those compounds will move. This question has aroused great interest in the development of pH control technologies coupled to soil remediation processes. In electrokinetic remediation processes, pH has usually been controlled by catholyte pH conditioning with acid solutions, applied to cases of heavy metals pollution. However, this method is not effective with pollutants that can be dissociated in anionic species. In this context, this paper presents a study of the electrokinetic remediation of soils polluted with 2,4-Dichlorophenoxyacetic acid, a common polar pesticide, enhanced with an anolyte pH conditioning strategy. A numerical study is proposed to evaluate the effectiveness of the strategy. Several numerical tests have been carried out for NaOH solutions with different concentrations as pH conditioning fluid. The results show that the anolyte pH conditioning strategy makes it possible to control the pH of the soil and, consequently, the chemical speciation of pollutant species. Thus, it is possible to achieve an important flux of pesticide into the anolyte compartment (electro-migration of anionic species and diffusive transport of acid species). This way, it possible to maximise the pesticide accumulation in this compartment, allowing a much more effective removal of pollutants from the soil than without the anolyte pH conditioning strategy.

Impact of the electrochemical process on the biodegradability of metronidazole and its by-products. AB - In this study, the monitoring of reactive oxygen species and the regeneration of the ferrous ions catalyst were performed during electro-Fenton (EF) process to highlight the influence of operating parameters. The removal of metronidazole (MTZ) was implemented in an electrochemical mono-compartment batch reactor under various ranges of current densities, initial MTZ and ferrous ions concentrations, and pH values. It was found that under 0.07 mA cm-2, 0.1 mM of ferrous ions and pH = 3, the efficiency of 100 mg L-1 MTZ degradation and mineralization were 100% within 20 min and 40% within 135 min of electrolysis, respectively. The highest hydrogen peroxide and hydroxyl radical concentrations, 1.4 mM and 2.28 mM respectively, were obtained at 60 min electrolysis at 0.07 mA cm-2. Improvement of the biodegradability was reached from 60 min of electrolysis with a BOD5/COD ratio above 0.4, which was reinforced by a respirometric study, that supports the feasibility of coupling electro-Fenton and biological treatment for the metronidazole removal. PMID- 29454172 TI - Toxicity of lanthanum oxide nanoparticles to the fungus Moniliella wahieum Y12T isolated from biodiesel. AB - Moniliella wahieum Y12T, isolated from biodiesel was used as a model organism to assess the use of lanthanum oxide (La2O3) (60-80 nm) and silver oxide (AgO) (10 40 nm) nanoparticles as potential fungal inhibitors. This is the first study to investigate the use of nanoscale La2O3 as a eukaryotic bio-inhibitor. The AgO nanoparticles were relatively effective at inhibiting the growth of M. wahieum Y12T. The half maximal effective concentration (EC50) for AgO was 0.012 mg/mL as compared with 4.63 mg/mL of La2O3. Fluorescein diacetate analysis showed that AgO nanoparticles significantly reduced metabolic activity in M. wahieum Y12T. The results of this study indicated that AgO nanoparticles can be a nonspecific inhibitor for the treatment of M. wahieum Y12T, a eukaryotic biodiesel contaminant. PMID- 29454173 TI - Photo-assisted electrochemical abatement of trifluralin using a cathode containing a C60-carbon nanotubes composite. AB - This work reports the potential application of modified gas-diffusion electrode (GDE) with C60-CNT composite, as a stable and efficient cathode material for degradation of trifluralin (TRL) pesticide by photo-assisted electrochemical (PE) process. C60-CNT composite was prepared and characterized. Subsequently, a novel C60-CNT composite modified GDE cathode was developed and the electrochemical and physical characteristics of the modified GDEs were studied. C60-CNT composite/GDE showed great efficiencies for electro-generating H2O2, owing to huge surface area and high conductivity. Afterwards, a comparative study of TRL oxidation via photolysis, anodic oxidation (AO) and PE processes using C60-CNT composite/GDE revealed the degradation percentages of 42.2, 48.5 and 93.4%, respectively, after 180 min of treatment. The TRL degradation followed a pseudo-first-order kinetics, being faster in the order: photolysis < AO < PE. The effects of various operational conditions were assessed on the degradation of TRL. From the results, PE process using C60-CNT composite/GDE exhibited great performance for the degradation of TRL (20 mg L-1) under its original pH, Na2SO4 electrolyte concentration of 0.05 mol L-1, applied current intensity of 300 mA, and flow rate of 12.5 L h-1. TOC results displayed that 92.8% of TRL was mineralized after 8 h of PE process. In addition, a plausible pathway for mineralization of TRL was proposed according to the identified by-products detected by means of gas chromatography-mass spectroscopy (GC-MS), High-performance liquid chromatography (HPLC) and ion chromatography analyses. PMID- 29454174 TI - Mastectomy patterns, but not rates, are changing in the treatment of early breast cancer. Experience of a single European institution on 2315 consecutive patients. AB - BACKGROUND: Recent literature reports that rates of mastectomy are increasing in early breast cancer. However, data from European institutions are limited and revealed conflicting results. We report on 15-year trends of mastectomy, mastectomy plus immediate reconstruction and contralateral prophylactic mastectomy (CPM) at an academic institution. METHODS: We identified women diagnosed with unilateral early breast cancer at stage 0-IIa, with tumour size <= 4 cm, between 2002 and 2016. Trends were assessed using the Cochrane-Armitage test. Multivariable logistic regression was used to identify factors associated with receipt of mastectomy plus immediate reconstruction. RESULTS: A total of 2315 patients were identified. Of them, 65.7% underwent breast conserving surgery (BCS), while 34.3% underwent mastectomy as upfront surgery. Two point four per cent also received CPM. Immediate reconstruction was performed in 36.0% of patients receiving mastectomy. There was no change in trends of mastectomy over the 15 years studied (p = 0.69), as well as in trends of patients undergoing CPM (p = 0.44). In contrast, rates of immediate reconstruction rose significantly over the study period (from 12.2% in 2002 to 62.7% in 2016, p < 0.0001). Women were more likely to receive mastectomy plus immediate reconstruction if they were aged 50 years or younger, or had tumours larger than 2 cm, or had non-invasive carcinoma. CONCLUSIONS: Our study suggests that rates of both mastectomy and CPM in early breast cancer are not increasing, while use of immediate reconstruction is on the rise.

AB - Research suggests that transgender young offenders are a uniquely vulnerable caseload that may benefit from speech pathology intervention to help bring their voice into alignment with their gender identity. However, no previous studies have investigated treatment efficacy in this population. This study investigated the impact of intensive voice feminisation therapy targeting fundamental frequency and oral resonance in a 17 year old transgender individual within a youth justice institution. Acoustic analysis, listener and self-ratings of vocal femininity, self-ratings of vocal satisfaction, a post-treatment structured interview, and pre- and post- treatment completion of the Transsexual Voice Questionnaire (TVQMtF) were utilised to determine treatment impact. Outcome measures indicated therapy was effective at increasing the client's vocal pitch and perceptually femininity without compromising vocal quality. However, the client was still not consistently perceived as female post-intervention and had difficulty implementing feminine speech strategies in discourse. This case study provides preliminary evidence for the effectiveness of intensive voice feminisation therapy in a youth offending population. This research also highlights the potential utility of speech pathologists working in youth justice settings, even when the timeframe for intervention is limited. Furthermore, this research paper validates the use of perceptual outcome measures in transgender voice work, by replicating previous findings in which significant correlations were found between perceptual ratings of vocal gender and client satisfaction. PMID- 29454178 TI - Caffeine use disorder: An item-response theory analysis of proposed DSM-5 criteria. AB - INTRODUCTION: Caffeine is a common psychoactive substance with a documented addictive potential. Caffeine withdrawal has been included in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), but caffeine use disorder (CUD) is considered to be a condition for further study. The aim of the current study is (1) to test the psychometric properties of the Caffeine Use Disorder Questionnaire (CUDQ) by using a confirmatory factor analysis and an item response theory (IRT) approach, (2) to compare IRT models with varying numbers of parameters and models with or without caffeine consumption criteria, and (3) to examine if the total daily caffeine consumption and the use of different caffeinated products can predict the magnitude of CUD symptomatology. METHODS: A cross-sectional study was conducted on an adult sample (N = 2259). Participants answered several questions regarding their caffeine consumption habits and completed the CUDQ, which incorporates the nine proposed criteria of the DSM-5 as well as one additional item regarding the suffering caused by the symptoms. RESULTS: Factor analyses demonstrated the unidimensionality of the CUDQ. The suffering criterion had the highest discriminative value at a higher degree of latent trait. The criterion of failure to fulfill obligations and social/interpersonal problems discriminate only at the higher value of CUD latent factor, while endorsement the consumption of more caffeine or longer than intended and craving criteria were discriminative at a lower level of CUD. Total daily caffeine intake was related to a higher level of CUD. Daily coffee, energy drink, and cola intake as dummy variables were associated with the presence of more CUD symptoms, while daily tea consumption as a dummy variable was related to less CUD symptoms. Regular smoking was associated with more CUD symptoms, which was explained by a larger caffeine consumption. CONCLUSIONS: The IRT approach helped to determine which CUD symptoms indicate more severity and have a greater discriminative value. The level of CUD is influenced by the type and quantity of caffeine consumption. PMID- 29454177 TI - Tobacco harm perceptions and use among sexual and gender minorities: findings from a national sample of young adults in the United States. AB - INTRODUCTION: In the United States, the prevalence of tobacco use among sexual and gender minorities (SGM) is higher compared to their non-SGM counterparts. Tobacco harm perceptions have gone largely unexamined as a potential mechanism supporting disproportionate tobacco use among this population. The purpose of this study was to examine differences between SGM and non-SGM young adults in harm perceptions of various tobacco products and tobacco use behavior and whether low tobacco-related harm perceptions moderate the relationship between identifying as a SGM and tobacco use behavior. METHODS: This study used data from Wave 10 of the Truth Initiative Young Adult Cohort Study, a sample of U.S. young adults (ages 18-34). Data were collected from September to October 2016 and the study sample included 3089 individuals. Demographics, past 30-day use of cigarettes, little cigars/cigarillos/bidis and electronic cigarettes were assessed. Absolute and relative harm perceptions of these products were also examined. RESULTS: Identifying as a SGM and low tobacco harm perceptions were found to be positively associated with past 30-day tobacco use. There was no interaction between SGM status and harm perceptions on past 30-day tobacco use CONCLUSIONS: Findings confirm that SGM young adults continue to disproportionately use tobacco products, compared to non-SGM young adults. More research is needed to understand moderators of the relationship between SGM status and tobacco use in young adults. PMID- 29454179 TI - Race/ethnicity and racial group composition moderate the effectiveness of mindfulness-based relapse prevention for substance use disorder. AB - INTRODUCTION: Mindfulness-based relapse prevention has shown promise as a treatment for substance use disorder but its efficacy according to racial/ethnic minority status and group composition is unknown. METHOD: This is a secondary analysis of existing data (Bowen et al., 2014) testing individual race/ethnicity and racial/ethnic group composition as moderators of mindfulness-based relapse prevention (MBRP). Participants (N = 191; 29% female; 47% racial/ethnic minority; mean age = 39) with substance use disorder were randomized to MBRP or relapse prevention (RP). Outcomes were heavy drinking days (HDD) and drug use days (DUD) 12 months after treatment completion. Negative binominal regression models were conducted. RESULTS: Analyses accounted for drug of choice. Individual race/ethnicity was a significant moderator of substance use outcomes. White participants had lower HDD in MBRP than RP (IRR = 0, 95% CI: 0,0), whereas for minority participants, there was no treatment difference in HDD. Conversely, minorities had lower DUD in MBRP than RP (IRR = 0.03, 95% CI: 0.01, 0.10), whereas for whites there was no treatment difference in DUD. Group racial/ethnic composition was a significant moderator. Participants in groups with more than half whites had lower HDD in MBRP than RP (IRR = 0.01, 95% CI: 0, 0.09), whereas for participants in groups with more than half minorities there was no treatment difference in HDD. Exploratory analyses suggested MBRP resulted in better outcomes than RP when individual race/ethnic status was reflected in the group race/ethnicity (i.e., whites in groups with more than half whites or minorities in groups with more than half minorities). CONCLUSIONS: Among whites, MBRP appears to be more effective than RP in preventing heavy drinking relapse. However, among racial/ethnic minorities, MBRP appears to more effective than RP in preventing drug use relapse. This suggests that the interaction between individual race/ethnicity and group composition may influence primary outcomes. PMID- 29454181 TI - Brainstem dysfunction heralding disseminated cryptococcosis. AB - Cryptococcal meningoencephalitis is one of the most common central nervous system infections affecting immunocompromised patients. However, brainstem involvement is extremely rare and may represent a diagnostic challenge to clinicians. We report a non-HIV infected, chronically immunosuppressed, patient with fatal disseminated cryptococcosis presented with subcutaneous masses at both thighs and progressive brainstem dysfunction. Magnetic resonance imaging demonstrated multiple brainstem infarcts likely derived from small vessel vasculopathy. Anti fungal treatment led to partial neurologic improvement but the patient succumbed to a fatal sepsis from hospital-acquired pneumonia. PMID- 29454182 TI - The positive effect of venlafaxine on central motor conduction. AB - OBJECTIVES: Using the triple stimulation technique (TST) and conventional transcranial magnetic stimulation (TMS), this study was designed to investigate the effect of venlafaxine on central motor conduction in healthy adults. PATIENTS AND METHODS: In this crossover, self-controlled trial, eight healthy adult volunteers were randomly divided into groups A and B. In group A, the volunteers were administered 1 venlafaxine capsule once daily for 7 consecutive days, followed by a 3-day break. Next, volunteers in this group received 1 placebo capsule once daily for 7 consecutive days. Group B received the treatments in the opposite order. The index finger tapping test, grip strength test, TST and conventional TMS examination for each hand were recorded before and one week after the administration of venlafaxine or placebo. RESULTS: Compared to the placebo stage, in the venlafaxine stage, the number of index finger taps was significantly increased for both hands, and the TST amplitude and area ratios were significantly increased. The improvement in the TST amplitude ratio was significantly and positively correlated with the improvements in performance on the index finger tapping test. CONCLUSION: Venlafaxine positively regulates central motor conduction in healthy adults.

AB - BACKGROUND: Early intervention in depression has been critical to prevent its negative impact including suicide. Recent blood biomarker studies for major depressive disorder (MDD) have suggested that tryptophan-kynurenine and lipid related metabolites are involved in the pathophysiology of MDD. However, there have been limited studies investigating these blood biomarkers in first-episode drug-naive MDD, which are particularly important for early intervention in depression. METHODS: As an exploratory pilot case-control study, we examined the above blood biomarkers, and analyzed how these biomarkers are associated with clinical variables in first-episode drug-naive MDD patients, based on metabolome/lipidome analysis. RESULTS: Plasma tryptophan and kynurenine levels were significantly lower in MDD group (N = 15) compared to healthy controls (HC) group (N = 19), and plasma tryptophan was the significant biomarker to identify MDD group (area under the curve = 0.740). Lower serum high density lipoprotein cholesterol (HDL-C) was the predictive biomarker for severity of depression in MDD group (R2 = 0.444). Interestingly, depressive symptoms were variously correlated with plasma tryptophan-kynurenine and lipid related metabolites. Moreover, plasma tryptophan-kynurenine metabolites and cholesteryl esters (CEs) were significantly correlated in MDD group, but not in HC group. LIMITATIONS: This study had small sample size, and we did not use the multiple test correction. CONCLUSIONS: This is the first study to suggest that not only tryptophan-kynurenine metabolites but also HDL-C and CEs are important blood biomarkers for first-episode drug-naive MDD patients. The present study sheds new light on early intervention in clinical practice in depression, and further clinical studies especially large-scale prospective studies are warranted.

AB - Epichloe endophytes form mutualistic symbiotic associations with aerial tissues of temperate grasses. Intercalary growth of hyphae within the leaves enables fungal growth to be synchronized with host leaf growth, leading to formation of a highly structured and tightly regulated symbiotic network. Mutations in fungal genes that disrupt cell-cell fusion and other key signalling pathways lead to an antagonistic interaction characterized by unregulated growth of endophytic hyphae and detrimental effects on host growth. Transcriptome analysis of these mutant associations provides key insights into the regulation of the symbiosis. In nature a similar switch in growth occurs when hyphae transition into the sexual cycle forming stromata that abort host inflorescences. Endophyte infection of the grass host leads to a major reprogramming of host metabolism and alters host development. Changes in endophyte cell wall structure and the repertoire of effectors secreted into the host apoplast accompany establishment of a mutualistic interaction within the leaves. PMID- 29454184 TI - Exploration and exploitation of the environment for novel specialized metabolites. AB - Microorganisms are Nature's little engineers of a remarkable array of bioactive small molecules that represent most of our new drugs. The wealth of genomic and metagenomic sequence data generated in the last decade has shown that the majority of novel biosynthetic gene clusters (BGCs) is identified from cultivation-independent studies, which has led to a strong expansion of the number of microbial taxa known to harbour BGCs. The large size and repeat sequences of BGCs remain a bioinformatic challenge, but newly developed software tools have been created to overcome these issues and are paramount to identify and select the most promising BGCs for further research and exploitation. Although heterologous expression of BGCs has been the greatest challenge until now, a growing number of polyketide synthase (PKS) and non-ribosomal peptide synthetase (NRPS)-encoding gene clusters have been cloned and expressed in bacteria and fungi based on techniques that mostly rely on homologous recombination. Finally, combining ecological insights with state-of-the-art computation and molecular methodologies will allow for further comprehension and exploitation of microbial specialized metabolites. PMID- 29454185 TI - Preterm infants undergoing laparotomy for necrotizing enterocolitis or spontaneous intestinal perforation display evidence of impaired cerebrovascular autoregulation. AB - BACKGROUND: Preterm infants requiring surgery are at risk of impaired neurocognitive development caused, possibly, by cerebral ischemia associated with impaired cerebrovascular autoregulation (CAR). We evaluated CAR before, during, and after laparotomy. STUDY DESIGN: This was a hypothesis generating prospective observational cohort study. SUBJECTS: We included preterm infants requiring surgery for necrotizing enterocolitis (NEC) or spontaneous intestinal perforation (SIP). Before, during, and after surgery we measured cerebral oxygen saturation using NIRS and calculated cerebral fractional tissue oxygen extraction (cFTOE). OUTCOME MEASURES: Impaired CAR was defined if correlation coefficients (rho) between mean cFTOE and mean arterial blood pressure values were <=-0.30 with P < .05. We used logistic regression analyses to determine factors associated with impaired CAR. RESULTS: Nineteen infants with median (IQR) GA 27.6 weeks (26.6 31.0), birth weight 1090 g (924-1430), and postnatal age 9 days (7-12) were included. CAR was impaired more often during surgery than before (12 versus 3, P = .02) or after (12 versus 0, P < .01). A higher PCO2 level was associated with impaired CAR during surgery (OR 3.04, 95% CI, 1.11-8.12 for every 1 kPa increase). CONCLUSIONS: More than half of preterm infants with NEC or SIP displayed evidence of impaired CAR during laparotomy. Further research should focus on mechanisms contributing to impaired CAR in preterm infants during surgery. PMID- 29454186 TI - Use of pasteurised human donor milk across neonatal networks in England. AB - OBJECTIVES: To describe the use of pasteurised human donor milk (pHDM) in England and the influence of a human milk bank in the network. DESIGN: Prospective observational study SETTING: All 163 neonatal units (23 networks) in England 2012 2013. PATIENTS: Preterm infants born at <32 weeks gestational age (GA). MAIN OUTCOME MEASURES: Proportion of infants and care-days fed pHDM during the first 30 postnatal days by network METHODS: We extracted daily patient-level data from the National Neonatal Research Database (NNRD). We fitted a logistic regression of pHDM exposure on the presence of a pHDM bank within the network, with GA, BW z score and network as covariates. Significance was assessed by the likelihood ratio (chi-squared) test. RESULTS: Data for 13,463 infants were included in the study. Across the networks, the proportion (95%CI) of infants ranged from 2.0% (1.0, 3.0) to 61.0% (57.4%, 64.6%), and the proportion of care-days in which pHDM was fed from 0.08% (0.04%, 0.10%) to 21.9% (19.9%, 24.0%). In three networks <5%, and in seven networks >30% of infants received any pHDM. Variation in the use of pHDM across networks remained significant after adjustment for presence of a human milk bank within the network and all covariates (p < 0.001). CONCLUSIONS: Wide variation of pHDM use in England is not fully explained by presence of a pHDM bank or patient characteristics. This suggests clinical uncertainty about the use of pHDM. PMID- 29454187 TI - Investigating the time-dependent zeta potential of wood surfaces. AB - This work reports on streaming potential measurements through natural capillaries in wood and investigates the cause of a time-dependent zeta potential measured during the equilibration of wood cell-walls with an electrolyte solution. For the biomaterial, this equilibration phase takes several hours, which is much longer than for many other materials that have been characterized by electrokinetic measurements. During this equilibration phase the zeta potential magnitude is decaying due to two parallel mechanisms: (i) the swelling of the cell-wall which causes a dimensional change reducing the charge density at the capillary interface; (ii) the transport of ions from the electrolyte solution into the permeable cell-wall which alters the electrical potential at the interface by internal charge compensation. The obtained results demonstrate the importance of equilibration kinetics for an accurate determination of the zeta potential, especially for materials that interact strongly with the measurement electrolyte. Moreover, the change in zeta potential with time can be correlated with the bulk swelling of wood if the effect of electrolyte ion diffusion is excluded. This study shows the potential of streaming potential measurements of wood, and possibly of other hygroscopic and nanoporous materials, to reveal kinetic information about their interaction with liquids, such as swelling and ion uptake.

AB - Triazole tethered 7-chloroquinoline-pyrimidine-5-carboxylate hybrids were synthesized and evaluated for antiplasmodial activity against chloroquine sensitive (CQS) NF54 strain of Plasmodium falciparum. The most active hybrids of the series were further screened against the chloroquine resistant (CQR) Dd2 strain of the parasite and for in vitro cytotoxicity against mammalian Vero cell lines. Further, their physico-chemical properties, binding studies with hemin (monomeric &MU-oxo dimeric) and DNA [pUC-18, calf thymus (CT)] led us to plausible proposed binding mode of the most active member of the present series. PMID- 29454188 TI - Modified two-step emulsion solvent evaporation technique for fabricating biodegradable rod-shaped particles in the submicron size range. AB - HYPOTHESIS: Though the emulsion solvent evaporation (ESE) technique has been previously modified to produce rod-shaped particles, it cannot generate small sized rods for drug delivery applications due to the inherent coupling and contradicting requirements for the formation versus stretching of droplets. The separation of the droplet formation from the stretching step should enable the creation of submicron droplets that are then stretched in the second stage by manipulation of the system viscosity along with the surface-active molecule and oil-phase solvent. EXPERIMENTS: A two-step ESE protocol is evaluated where oil droplets are formed at low viscosity followed by a step increase in the aqueous phase viscosity to stretch droplets. Different surface-active molecules and oil phase solvents were evaluated to optimize the yield of biodegradable PLGA rods. Rods were assessed for drug loading via an imaging agent and vascular-targeted delivery application via blood flow adhesion assays. FINDINGS: The two-step ESE method generated PLGA rods with major and minor axis down to 3.2 um and 700 nm, respectively. Chloroform and sodium metaphosphate was the optimal solvent and surface-active molecule, respectively, for submicron rod fabrication. Rods demonstrated faster release of Nile Red compared to spheres and successfully targeted an inflamed endothelium under shear flow in vitro and in vivo. PMID- 29454190 TI - Potholing of the hydrophobic heme oxygenase-1 western region for the search of potent and selective imidazole-based inhibitors. AB - Here we report the design, synthesis, and molecular modeling of new potent and selective imidazole-based HO-1 inhibitors in which the imidazole nucleus and the hydrophobic groups are linked by a phenylethanolic spacer. Most of the tested compounds showed a good inhibitor activity with IC50 values in the low micromolar range, with two of them (1b and 1j) exhibiting also high selectivity toward HO-2. These results were obtained by the idea of potholing the entire volume of the principal hydrophobic western region with an appropriate ligand volume. Molecular modeling studies showed that these molecules bind to the HO-1 in the consolidated fashion where the imidazolyl moiety coordinates the heme iron while the aromatic groups are stabilized by hydrophobic interaction in the western region of the binding pocket. Finally, the synthesized compounds were analyzed for in silico ADME-Tox properties to establish oral drug-like behavior and showed satisfactory results. PMID- 29454191 TI - Show me the way: rust effector targets in heterologous plant systems. AB - For years, the study of rust fungal effectors has been impeded by the lack of molecular genetic tools in rust pathosystems. The recent use of heterologous plants to perform effector screens (effectoromics)-including effector localisation (cellular targets) and protein interactors (molecular targets) in plant cells-has changed the game. These screens revealed that many candidate effectors from various rust fungi target specific plant cell compartments, including chloroplasts, and associate with specific plant protein complexes. Such information represents unparalleled opportunities to understand how effectors sustain extreme parasitic interactions and obligate biotrophy. Despite their limitations, we here portray how the use of heterologous expression systems has been essential for gaining new insight into rust effectors. PMID- 29454192 TI - Phytophthora sojae effectors orchestrate warfare with host immunity. AB - Phytophthora sojae is one of the most damaging plant pathogens of soybean. To aid establishment of a compatible interaction with its host, P. sojae deploys many secreted effectors. These effectors act either in the apoplastic space to cope with hostile conditions or inside of host cells to reprogram host physiology favoring pathogen growth. Effectors have been used as molecular probes, which revealed in Phytophthora that effectors execute their virulence function via manipulating host targets. In addition, recent studies have discovered 'pseudo effectors' in Phytophthora that act as decoys to shield virulence effectors from host defense, a new paradigm in plant-pathogen interactions. PMID- 29454193 TI - Revealing metabolic storage processes in electrode respiring bacteria by differential electrochemical mass spectrometry. AB - In this work we employ differential electrochemical mass spectrometry (DEMS) in combination with static and dynamic electrochemical techniques for the study of metabolic processes of electrochemically active bacteria. CO2 production during acetate oxidation by electrode respiring bacteria was measured, in-vivo and online with a sensitivity of 6.5 ? 10-13 mol/s. The correlation of ion current and electrical current provides insight into the interaction of metabolic processes and extra-cellular electron transfer. In low-turnover CVs, two competing potential dependent electron transfer mechanisms were observed and formal potentials of two redox systems that are involved in complete oxidation of acetate to CO2 were determined. By balancing charge and carbon flows during dynamic measurements, two significant storage mechanisms in electrochemically active bacteria were identified: 1) a charge storage mechanism that allows substrate oxidation to proceed at a constant rate despite of external current flowing in cathodic direction. 2) a carbon storage mechanism that allows the biofilm to take up acetate at an unchanged rate at very low potentials even though the oxidation to CO2 stops. These storage capabilities allow a limited decoupling of electrical current and CO2 production rate. PMID- 29454194 TI - Diagnostic and treatment services for patients with Psychogenic Nonepileptic Seizures (PNES): A survey of health professionals in urban China. AB - PURPOSE: This study is intended to provide an overview of diagnostic and treatment services for patients with psychogenic nonepileptic seizures (PNES) across China. METHODS: Using a questionnaire devised by the PNES Task Force of Neuropsychiatry Commission of the International League Against Epilepsy (ILAE), we conducted a survey among Chinese health professionals at the Sixth Advanced International Course: Clinical Epileptology. Descriptive analyses were performed. RESULTS: Responses from 102 eligible clinicians were analysed. Responses were received from urban areas in 20 provinces/municipalities around China. Most respondents were neurologists. The results showed that hospitals in urban China were mostly well-equipped, and that health professionals' understanding of PNES largely reflected current international expert opinion. However, many of the participants would not actually make the diagnosis, and most provided neither follow-up nor treatment (especially psychotherapy) for patients with PNES. Only about one third of the patients diagnosed with PNES were estimated to receive at least one appointment for psychological treatment. In the opinion of the respondents, tacit trauma (neglect and stress) play an important role in the development of PNES. The main obstacles to patients with PNES accessing health services for their condition were thought to be lack of knowledge or awareness among health professionals, patients and society. CONCLUSION: Despite good access to equipment, diagnostic and treatment services for patients with PNES in China are currently deficient. Education programs about PNES with different target groups, and more effective referral and social security systems emerge as particular development needs from this survey. PMID- 29454195 TI - CHRNA4 variant causes paroxysmal kinesigenic dyskinesia and genetic epilepsy with febrile seizures plus? AB - PURPOSE: Paroxysmal kinesigenic dyskinesia (PKD) and epilepsy are thought to have a shared genetic etiology. PRRT2 has been identified as a causative gene of both disorders. In this study, we aim to explore the potential novel causative gene in a PRRT2-negative family with three individuals diagnosed with PKD or genetic epilepsy with febrile seizures plus (GEFS+). METHODS: Clinical data were collected from all the affected and unaffected members of a PKD/GEFS+ family. The Brain magnetic resonance imaging and 24 h video-EEG of all three affected members were analyzed. Targeted gene-panel sequencing was used to detect the genetic defect in genomic DNAs of three affected and five normal individuals. Co segregation analysis of putatively pathogenic mutations with the phenotype was carried out in all the family members alive to examine the inheritance status. RESULTS: The inheritance model of this pedigree was autosomal dominant. A novel, fully co-segregated mutation (NM_000744: c.979G > A) in CHRNA4 was identified in the family with three individuals diagnosed with PKD or GEFS+. CONCLUSIONS: CHRNA4 may be a novel gene causing of PKD and GEFS+. Our study extends the genotypic-phenotypic spectrum of combined epileptic and dyskinetic syndromes, and provides a genetic linkage between PKD and GEFS+. PMID- 29454197 TI - Cigarette butts may have low toxicity to soil-dwelling invertebrates: Evidence from a land snail. AB - Cigarette butts are a common form of litter that is often deposited on soil, where toxins from butts may affect soil-dwelling organisms. We examined possible toxicity of cigarette butts to the woodland snail Anguispira alternata using a toxicity study with cigarette butt effluent and a lab-based habitat choice experiment in which snails could feed or rest on areas with different butt densities. No mortality occurred during the 32-day toxicity study, which used six effluent concentrations ranging from 0 to 4butts/l (0 to 0.92butts/kg of soil). Neither food consumption nor snail growth differed among the effluent concentrations. When provided a choice among four habitats with 0 to 4 cigarette butts, snails selected to preferentially rest in the 0-butt habitat and avoided the 4-butt habitat. This distribution pattern was strong during the first wk. but became weaker over time and largely disappeared by the end of the 3-wk experiment. Snails did not discriminate among butt densities when feeding. This is the first toxicity test using cigarette butts on soil-dwelling invertebrates. Declining aversion to cigarette butts over a 3-wk period may indicate declining toxicity of terrestrially deposited butts as they age, but further testing is needed. PMID- 29454196 TI - Sexually transmitted infections and immune activation among HIV-infected but virally suppressed youth on antiretroviral therapy. AB - BACKGROUND: Human immunodeficiency virus (HIV) infection is associated with chronic immune activation, and concurrent sexually transmitted infections (STIs) may increase immune activation. OBJECTIVES: Because HIV-infected youth are at high risk of STIs and little is known about the impact of STIs on immune activation in HIV-infected youth, we conducted an exploratory study examining the association between STIs and systemic inflammation and immune activation among HIV-infected adolescents. STUDY DESIGN: Forty-nine behaviorally infected U.S. youth ages 18-24 years with baseline CD4+ T-cells >350 who maintained viral suppression on therapy by week 48 were included. Evaluation for STIs (herpes simplex virus [HSV], Chlamydia trachomatis, syphilis, Neisseria gonorrhoeae) was conducted as standard of care and reported on case report forms. Measures of T cell subsets, systemic immune activation, and soluble factors were examined at week 48 for differences between participants with an STI diagnosis during the 48 weeks compared to those without an STI. RESULTS: Forty-three participants (88%) were male; 57% had baseline CD4+ T-cell counts >500 cells/mm3. Eighteen youth were reported to have >=1 STI. At week 48, participants with STIs demonstrated lower CD4+ T-cell counts (any STI vs. no STI, p = 0.024; HSV vs. no STI, p = 0.022) and evidence of increased systemic immune activation, including higher CD57 intensity, higher HLA-DR intensity, and lower CD28 percentage, when compared to those without STIs. There were no differences in soluble factors between STI groups. CONCLUSIONS: Results indicate novel activation of CD4+ T-cells among HIV infected youth who have STIs other than HSV, which may contribute to disease progression. PMID- 29454198 TI - Long-term exposure to air pollution and the risk of suicide death: A population based cohort study. AB - Suicide is a major public health problem. Previous studies have reported a significant association between acute exposure to air pollution and suicide; little attention has been paid to the long-term effects of air pollution on risk of suicide. We investigated whether long-term exposure to particulate matter of <=10MUm in diameter (PM10), nitrogen dioxide (NO2), and sulfur dioxide (SO2) would be associated with a greater risk of death by suicide. The study sample comprised 265,749 adults enrolled in the National Health Insurance Service National Sample Cohort (2002-2013) in South Korea. Suicide death was defined as per ICD-10 code. Data on air pollution exposure used nationwide monitoring data, and individual exposure levels were assigned using geographic information systems. Air pollution exposure was categorized as the interquartile range (IQR) and quartiles. Hazards ratios (HRs) were calculated for the occurrence of suicide death after adjusting for potential covariates. During the study period, 564 (0.2%) subjects died from suicide. Increases in IQR pollutants (7.5MUg/m3 for PM10, 11.8ppb for NO2, and 0.8ppb for SO2) significantly increased HR for suicide death [PM10: HR=3.09 (95% CI: 2.63-3.63); NO2: HR=1.33 (95% CI: 1.09-1.64); and SO2: HR=1.15 (95% CI: 1.07-1.24)]. Compared with the lowest level of air pollutants (Quartile 1), the risk of suicide significantly increased in the highest quartile level (Quartile 4) for PM10 (HR=4.03; 95% CI: 2.97-5.47) and SO2 (HR=1.65; 95% CI: 1.29-2.11) and in the third quartile for NO2 (HR=1.52; 95% CI: 1.17-1.96). HRs for subjects with a physical or mental disorder were higher than that those for subjects without the disorder. Subjects living in metropolitan areas were more vulnerable to long-term PM10 exposure than those living in non metropolitan areas. Long-term exposure to air pollution was associated with a significantly increased risk of suicide death. People having underlying diseases or living in metropolitan areas may be more susceptible to high air pollution exposure. PMID- 29454199 TI - Benthic nitrite exchanges in the Seine River (France): An early diagenetic modeling analysis. AB - Nitrite is a toxic intermediate compound in the nitrogen (N) cycle. Elevated concentrations of nitrite have been observed in the Seine River, raising questions about its sources and fate. Here, we assess the role of bottom sediments as potential sources or sinks of nitrite along the river continuum. Sediment cores were collected from two depocenters, one located upstream, the other downstream, from the largest wastewater treatment plant (WWTP) servicing the conurbation of Paris. Pore water profiles of oxygen, nitrate, nitrite and ammonium were measured. Ammonium, nitrate and nitrite fluxes across the sediment water interface (SWI) were determined in separate core incubation experiments. The data were interpreted with a one-dimensional, multi-component reactive transport model, which accounts for the production and consumption of nitrite through nitrification, denitrification, anammox and dissimilatory nitrate reduction to ammonium (DNRA). In all core incubation experiments, nitrate uptake by the sediments was observed, indicative of high rates of denitrification. In contrast, for both sampling locations, the sediments in cores collected in August 2012 acted as sinks for nitrite, but those collected in October 2013 released nitrite to the overlying water. The model results suggest that the first step of nitrification generated most pore water nitrite at the two locations. While nitrification was also the main pathway consuming nitrite in the sediments upstream of the WWTP, anammox dominated nitrite removal at the downstream site. Sensitivity analyses indicated that the magnitude and direction of the benthic nitrite fluxes most strongly depend on bottom water oxygenation and the deposition flux of labile organic matter. PMID- 29454200 TI - Effect of clonal integration on nitrogen cycling in rhizosphere of rhizomatous clonal plant, Phyllostachys bissetii, under heterogeneous light. AB - Clonal integration plays an important role in clonal plant adapting to heterogeneous habitats. It was postulated that clonal integration could exhibit positive effects on nitrogen cycling in the rhizosphere of clonal plant subjected to heterogeneous light conditions. An in-situ experiment was conducted using clonal fragments of Phyllostachys bissetii with two successive ramets. Shading treatments were applied to offspring or mother ramets, respectively, whereas counterparts were treated to full sunlight. Rhizomes between two successive ramets were either severed or connected. Extracellular enzyme activities and nitrogen turnover were measured, as well as soil properties. Abundance of functional genes (archaeal or bacterial amoA, nifH) in the rhizosphere of shaded, offspring or mother ramets were determined using quantitative polymerase chain reaction. Carbon or nitrogen availabilities were significantly influenced by clonal integration in the rhizosphere of shaded ramets. Clonal integration significantly increased extracellular enzyme activities and abundance of functional genes in the rhizosphere of shaded ramets. When rhizomes were connected, higher nitrogen turnover (nitrogen mineralization or nitrification rates) was exhibited in the rhizosphere of shaded offspring ramets. However, nitrogen turnover was significantly decreased by clonal integration in the rhizosphere of shaded mother ramets. Path analysis indicated that nitrogen turnover in the rhizosphere of shaded, offspring or mother ramets were primarily driven by the response of soil microorganisms to dissolved organic carbon or nitrogen. This unique in-situ experiment provided insights into the mechanism of nutrient recycling mediated by clonal integration. It was suggested that effects of clonal integration on the rhizosphere microbial processes were dependent on direction of photosynthates transport in clonal plant subjected to heterogeneous light conditions. PMID- 29454201 TI - Nitrous oxide emissions from near-zero water exchange brackish recirculating aquaculture systems. AB - The development of intensive recirculating aquaculture systems (RAS) with low water exchange has accelerated in recent years as a result of environmental, economic and other concerns. In these systems, fish are commonly grown at high density, 50 to 150kg/m3, using high-protein (30%-60%) feeds. Typically, the RAS consists of a solid treatment and a nitrification unit; in more advanced RAS, there is an additional denitrification step. Nitrous oxide (N2O), a byproduct during nitrification and denitrification processes, is a potent greenhouse gas that destroys the ozone layer. The aim of this study was to measure and assess N2O emissions from a near-zero discharge land-based saline RAS. N2O flux was monitored from the RAS's fish tank, and moving-bed nitrification and activated sludge (with intrinsic C source) denitrification reactors. N2O emission potential was also analyzed in the laboratory. N2O flux from the denitrification reactors ranged between 6.5 and 48mg/day, equivalent to 1.27+/-1.01% of the removed nitrate-N. Direct analysis from the fish tank and nitrification reactors could not be performed due to high aeration, which diluted the N2O concentration to below detection limits. Thus, its potential emission was estimated in the laboratory: from the fishponds, it was negligible; from the nitrification reactor, it ranged between 0.4 and 2.8% of the total ammonia-N oxidized. The potential N2O emission from the denitrification reactor was 3.72+/-2.75% of the reduced nitrate-N, within the range found in the direct measurement. Overall, N2O emission during N transformation in a RAS was evaluated to be 885mg/kg feed or 1.36g/kg fish production, accounting for 1.23% of total N application. Consequently, it is estimated that N2O emission from aquaculture currently accounts for 2.4% of the total agricultural N2O emission, but will decrease to 1.7% by 2030. PMID- 29454202 TI - Global patterns of extreme drought-induced loss in land primary production: Identifying ecological extremes from rain-use efficiency. AB - Quantifying the ecological patterns of loss of ecosystem function in extreme drought is important to understand the carbon exchange between the land and atmosphere. Rain-use efficiency [RUE; gross primary production (GPP)/precipitation] acts as a typical indicator of ecosystem function. In this study, a novel method based on maximum rain-use efficiency (RUEmax) was developed to detect losses of ecosystem function globally. Three global GPP datasets from the MODIS remote sensing data (MOD17), ground upscaling FLUXNET observations (MPI BGC), and process-based model simulations (BESS), and a global gridded precipitation product (CRU) were used to develop annual global RUE datasets for 2001-2011. Large, well-known extreme drought events were detected, e.g. 2003 drought in Europe, 2002 and 2011 drought in the U.S., and 2010 drought in Russia. Our results show that extreme drought-induced loss of ecosystem function could impact 0.9% +/- 0.1% of earth's vegetated land per year and was mainly distributed in semi-arid regions. The reduced carbon uptake caused by functional loss (0.14 +/- 0.03 PgC/yr) could explain >70% of the interannual variation in GPP in drought-affected areas (p <= 0.001). Our results highlight the impact of ecosystem function loss in semi-arid regions with increasing precipitation variability and dry land expansion expected in the future. PMID- 29454203 TI - Metals and arsenic in fish from a Ramsar site under past and present human pressures: Consumption risk factors to the local population. AB - The risk of metals and As in seafood for traditional populations living in a Marine Protected Areas (MPA) is seldom assessed, although the risk of human exposure to contaminants is one of the indicators associated with the socioeconomic goals of MPAs. The current study aimed to estimate the potential risk of some metals (Cd, Pb, and Zn) and arsenic (As) for human health through the ingestion of fish locally harvested in a Ramsar site, the Cananeia-Iguape Peruibe Environmental Protected Area (APA-CIP). Previous studies showed environmental impacts in this area due to former mining activities and urbanization. Cathorops spixii, a catfish largely consumed by the local population, was collected along the estuary in three seasons with different rain regimes. Metals and As loads in muscle tissue were quantified and it was estimated (i) the target hazard quotient (THQ) and (ii) the daily intake (EDI) for metals and As, (iii) the cancer risk (CRisk) only for As, and (iv) the number of eligible meals per month. Cd, Pb, and As were found at concentrations above action levels for human consumption. Depending on the level of exposure of the local population, the consumption of C. spixii may pose risk to human health. Highest THQs were estimated for fish collected in sites closer to the main contamination sources in the APA-CIP, i.e. the mouth of Ribeira de Iguape River (P1) and the city of Cananeia (P4, P5, and P6). Arsenic showed high levels of cancer risk, although restricted to the area close to the city. The exposure of the local population to metal and As contaminated seafood cannot be disregarded in environmental studies and management of the APA-CIP. PMID- 29454204 TI - Scanning vertical distributions of typical aerosols along the Yangtze River using elastic lidar. AB - In recent years, China has experienced heavy air pollution, especially haze caused by particulate matter (PM). The compositions, horizontal distributions, transport, and chemical formation mechanisms of PM and its precursors have been widely investigated in China based on near-ground measurements. However, the understanding of the distributions and physical and chemical processes of PM in the vertical direction remains limited. In this study, an elastic lidar was employed to investigate the vertical profiles of aerosols along the Yangtze River during the Yangtze River Campaign of winter 2015. Some typical aerosols were identified and some events were analyzed in three cases. Dust aerosols can be transported from the Gobi Desert to the Yangtze River basin across a long distance at both low and high altitudes in early December. The transport route was perpendicular to the ship track, suggesting that the dust aerosols may have affected a large area. Moreover, during transport, some dust was also affected by the areas below its transport route since some anthropogenic pollutants were mixed with the dust and changed some of its optical properties. Biomass-burning aerosols covering a distant range along the Yangtze River were identified. This result directly shows the impact areas of biomass-burning aerosols in some agricultural fields. Some directly emitted aerosol plumes were observed, and direct effects of such plumes were limited both temporally and spatially. In addition, an aerosol plume with very low linear depolarization ratios, probably formed through secondary processes, was also observed. These results can help us better understand aerosols in large spatial scales in China and can be useful to regional haze studies. PMID- 29454205 TI - How can local representations of changes of the availability in natural resources assist in targeting conservation? AB - The use and appropriation of natural resources by human groups may be strongly related to the perception that these groups have of the abundance or scarcity of these resources. Researches on environmental representation can be useful to understand the criteria involved in the selection and use of natural resources, to verify if people realize changes in the availability of these resources and the possible causes of these changes and to elaborate conservation strategies, if necessary. However, if people are not realizing these changes, of if they do not perceive themselves as a cause of such scarcity, the developing of conservation strategies will be very difficult to implement. We investigated the drivers of sustainable harvest of Syagrus coronata (Mart.) Becc. (ouricuri palm) leaves by the Fulni-o indigenous people in northeastern Brazil and accessed the representation of changes in the availability of the populations of this species over time. We obtained information about events that, from the point of view of the palm harvesters, pose threats to S. coronata populations. More experienced local harvesters tend to harvest leaves in a more sustainable manner than did young and inexperienced harvesters. The Fulni-o reported a decline in S. coronata populations. However, they primarily associate such decline to the farming practices of non-indigenous people that lease lands in the area. Although the Fulni-o people perceived a shortage of such resource, our findings indicate that the implementation of conservation strategies for the ouricuri palm may not be so easy to implement, once it affects one of their main income sources (land lease), which is recognize as the major threat for the species by harvesters. Ours results showed that the relationship between perception of scarcity and ease of implementation of conservation actions should be contextualized. PMID- 29454206 TI - Less sensitive of urban surface to climate variability than rural in Northern China. AB - In this study, the relationships between interannual variations of surface urban heat islands (SUHIs) and climate variability were studied in 31 cities of China for the period 2001-2016. For cold and dry Northern China, it was found that the interannual variations of SUHI intensity (SUHII, land surface temperature (LST) in urban minus rural) in urban cores was significantly (p<0.05) and negatively correlated with rural LST in 9 (in summer days (SDs)) and 8 (in winter days (WDs)) of the 15 northern cities, respectively. In addition, the daytime LST differences between hot summers and other summers and between cold winters and other winters were generally lower in urban cores (1.141 degrees C for SDs and 2.535 degrees C for WDs) than in rural areas (1.890 degrees C for SDs and 3.377 degrees C for WDs). The standard deviation was further used to reflect the interannual stabilities of LST, enhanced vegetation index (EVI) and white sky albedo (WSA). Interestingly, the standard deviations of LST across 2001-2016 were generally lower in urban cores (0.994 degrees C for SDs and 1.577 degrees C for WDs) than in rural areas (1.431 degrees C for SDs and 2.077 degrees C for WDs). Similar results were observed for EVI and WSA (winter). The results suggested that the urban surface is less sensitive to climate variability than rural areas in Northern China. Comparatively, most findings were less evident in hot and humid Southern China. Despite the whole world would become warmer or colder in future, the insensitivity of urban surface may mitigate its impacts in cold and dry Northern China. However, it does not mean that urbanization is totally good due to its environmental problem. PMID- 29454207 TI - Repeated treatments of ciprofloxacin and kresoxim-methyl alter their dissipation rates, biological function and increase antibiotic resistance in manured soil. AB - The dissipation of ciprofloxacin (CIP, 1.0 and 10.0mg/kg) and kresoxim-methyl (KM, 1.0 and 2.0mg/kg) in manure-amended soil, the variations in soil enzyme activities and microbial functional diversities, and CIP-induced bacterial community tolerances were studied using a chromatographic analysis, enzyme colorimetric and titration analyses, and the BIOLOG EcoPlate method. Three successive treatments of individual and combined samples of CIP and KM at low and high concentrations were performed at 60d intervals. The dissipation half-life of CIP increased, but that of KM decreased in manured soil with treatment frequency; furthermore, the combined treatment altered the dissipation rates of CIP and KM. A stronger inhibitory effect on the activities of soil neutral phosphatase and urease was observed in the individual KM treatment than in the individual CIP treatment. A similar inhibitory trend was also found in soil neutral phosphatase activity in the combined treatment at high concentration compared to that at low concentration, but the activity of soil catalase was enhanced in the early stages of the KM or CIP treatments. Meanwhile, the inhibitory trend on the overall activity and functional diversity of soil microorganisms was observed in the individual KM or CIP treatment, and the combined treatment exerted a greater suppression effect than that in the individual treatment. Bacterial community resistance to CIP increased significantly with increasing treatment frequency and concentration, and furthermore antibiotic resistance developed faster in the combined treatment than in the individual treatment. It was concluded that the repeated treatments of CIP and KM could alter their dissipation rates and soil enzyme activities, suppress microbial functional diversity, and increase bacterial community resistance to CIP in manured soil. PMID- 29454208 TI - Barrier effects of remote high mountain on atmospheric metal transport in the eastern Tibetan Plateau. AB - Anthropogenic metals adsorbed on suspended fine particles can be deposited on remote and inaccessible high mountains by long-range atmospheric transport. In this study, we investigated the cadmium (Cd) and lead (Pb) in the soils, mosses and rainfall of three transects on the Gongga Mountain, eastern Tibetan Plateau, to understand the mountain interception effects on their atmospheric transport. The concentrations of Cd and Pb in the soils and mosses displayed a pattern of eastern transect>northern transect>western transect. The distribution of Cd and Pb on the eastern transect increased from 2000 to 2900m a.s.l. (above sea level), decreased toward the timberline, and increased again with altitude; on the northern transect, it generally decreased with altitude whereas a distribution trend was not clearly observed on the western transect. The Cd and Pb concentrations in the rainfall of the eastern transect generally decreased with altitude, and they were higher inside forests than outside forests and temporally higher in the winter than the summer. The Pb isotopic ratios coupled with moss bio-monitoring distinguished anthropogenic sources of Cd and Pb on the eastern and northern transects, whereas bedrock weathering was the main source of Cd and Pb on the western transect. We proposed a conceptual model to delineate the effects of terrain, local climate and vegetation on the transport of atmospheric metals. Our results highlighted the high mountains in the eastern Tibetan Plateau as an effective natural barrier limiting atmospheric metal transport. PMID- 29454209 TI - Reconciling discrepancies in the source characterization of VOCs between emission inventories and receptor modeling. AB - Emission inventory (EI) and receptor model (RM) are two of the three source apportionment (SA) methods recommended by Ministry of Environment of China and used widely to provide independent views on emission source identifications. How to interpret the mixed results they provide, however, were less studied. In this study, a cross-validation study was conducted in one of China's fast-developing and highly populated city cluster- the Pearl River Delta (PRD) region. By utilizing a highly resolved speciated regional EI and a region-wide gridded volatile organic compounds (VOCs) speciation measurement campaign, we elucidated underlying factors for discrepancies between EI and RM and proposed ways for their interpretations with the aim to achieve a scientifically plausible source identification. Results showed that numbers of species, temporal and spatial resolutions used for comparison, photochemical loss of reactive species, potential missing sources in EI and tracers used in RM were important factors contributed to the discrepancies. Ensuring the consensus of species used in EIs and RMs, utilizing a larger spatial coverage and longer time span, addressing the impacts of photochemical losses, and supplementing emissions from missing sources could help reconcile the discrepancies in VOC source characterizations acquired using both approaches. By leveraging the advantages and circumventing the disadvantages in both methods, the EI and RM could play synergistic roles to obtain robust SAs to improve air quality management practices. PMID- 29454210 TI - Sunshine duration reconstruction in the southeastern Tibetan Plateau based on tree-ring width and its relationship to volcanic eruptions. AB - Sunshine is as essential as temperature and precipitation for tree growth, but sunshine duration reconstructions based on tree rings have not yet been conducted in China. In this study, we presented a 497-year sunshine duration reconstruction for the southeastern Tibetan Plateau using a width chronology of Abies forrestii from the central Hengduan Mountains. The reconstruction accounted for 53.5% of the variance in the observed sunshine during the period of 1961-2013 based on a stable and reliable linear regression. This reconstructed sunshine duration contained six sunny periods (1630-1656, 1665-1697, 1731-1781, 1793-1836, 1862 1895 and 1910-1992) and seven cloudy periods (1522-1629, 1657-1664, 1698-1730, 1782-1792, 1837-1861, 1896-1909 and 1993-2008) at a low-frequency scale. There was an increasing trend from the 16th century to the late 18th and early 19th centuries and a decreasing trend from the mid-19th to the early 21st centuries. Sunshine displayed inverse patterns to the local Palmer drought severity index on a multidecadal scale, indicating that this region likely experienced droughts under more sunshine conditions. The decrease in sunshine particularly in recent decades was mainly due to increasing atmospheric anthropogenic aerosols. In terms of the interannual variations in sunshine, weak sunshine years matched well with years of major volcanic eruptions. The significant cycles of the 2- to 7-year, 20.0-year and 35.2-year durations as well as the 60.2-year and 78.7-year durations related to the El-Nino Southern Oscillation, the Pacific Decadal Oscillation and the Atlantic Multidecadal Oscillation suggested that the variation in sunshine duration in the southeastern Tibetan Plateau was possibly affected by large-scale ocean-atmosphere circulations. PMID- 29454211 TI - Seasonality, water use and community management of water systems in rural settings: Qualitative evidence from Ghana, Kenya, and Zambia. AB - The sustainability of rural, community-managed water systems in sub-Saharan Africa depends in part on the ability of local water committees to repair breakdowns and carry out the operation and maintenance (O&M) of the system. Much of sub-Saharan Africa has two distinct seasons that affect the availability of water sources and how people use water. Little is known about how seasonality affects water system management. This qualitative study is based on 320 interviews and focus group discussions and examines the effects of season on community water use and management in Ghana, Kenya and Zambia. Participants revealed that seasonality affects water availability, water system breakdowns, resource mobilization, committee activity, and external support availability. In the rainy season, participants typically reported spending less time and money on water collection because rainwater harvesting and seasonal streams, ponds, wells and reservoirs are available. In the dry season, people used improved groundwater sources more often and spent more money and time collecting water. Although seasonal changes in household water demand and use have been examined previously, our data suggest that seasonality also influences community management through differential water system use, system breakdowns and management characteristics. We found that water committees generally have less money, time and access to external support during the rainy season, making them less able to carry out O&M. Our results suggest that community engagement should take place over a long period of time so that seasonal patterns in management can be understood and incorporated into water committee training. External support actors should make a more targeted effort to understand the cultural and economic patterns in a community in order to train committees with appropriate management strategies. PMID- 29454212 TI - Adsorption of sulfamethoxazole by magnetic biochar: Effects of pH, ionic strength, natural organic matter and 17alpha-ethinylestradiol. AB - Recent studies have shown the widespread occurrence of pharmaceuticals in the aquatic environment leading to increasing global concern on their potential adverse effects in the environment and public health. In this study, we evaluated the use of magnetic biochar derived from pine sawdust, one of New Zealand's major wood wastes, to remove an emerging contaminant, sulfamethoxazole (SMX), at different pH, ionic strength, natural organic matter (NOM) and a competing compound, 17alpha-ethinylestradiol (EE2). In single-solute system, the sorption of SMX onto magnetic biochar was found to be highly pH-dependent and slightly increased with increase in ionic strength. However, the effects of pH, ionic strength and NOM were relatively insignificant compared to the sorption inhibition caused by EE2 in binary-solute system. Both SMX and EE2 sorption onto the highly carbonised biochar in magnetic biochar were postulated to be due to the pi-pi electron donor acceptor and hydrophobic interaction. EE2 is more hydrophobic than SMX. Hence, strong competition between these compounds was identified where EE2 markedly inhibited the sorption of SMX onto magnetic biochar in all artificial environmental conditions studied. PMID- 29454213 TI - Spatio-temporal comparison of neustonic microplastic density in Hong Kong waters under the influence of the Pearl River Estuary. AB - Rivers are recognised as an important source of plastic debris in the open sea. The Pearl River in China is estimated to transport 0.1milliontonnes of plastic waste to the open sea annually. However, no empirical study has been conducted to assess the plastic contamination levels in the Pearl River Estuary. Hong Kong is situated in the east of the Pearl River Estuary; its western waters are strongly influenced by river discharge, whereas the eastern waters are unaffected by the freshwater plume. In this study, we quantified the neustonic plastic debris density in the western and eastern waters of Hong Kong. The mean microplastic (0.355-4.749mm) and large plastic debris (>=4.75mm) densities in the western side were 3.627 and 0.758n/m3, respectively. Seasonal comparisons indicated that both size classes of plastic debris were significantly more abundant by number in the rainy season than the dry season (p<0.001). However, the influence of rivers on plastic density at the sea surface may be highly restricted to the estuarine delta, as no significant spatial difference was found between the western and eastern waters. PMID- 29454214 TI - Observation of the degradation of three types of plastic pellets exposed to UV irradiation in three different environments. AB - Plastic debris represents one of the most prevalent and persistent pollution problems in the marine environment. In particular, microplastics that are mainly degraded from larger plastic debris have become a growing environmental concern. However, studies on the degradation of plastics in the aquatic environment that hydrobios reside in have been limited, while several studies regarding the degradation of plastics have been conducted under outdoor or accelerated weathering conditions. Thus, observation of the degradation of three types of virgin plastic pellets exposed to UV irradiation in three different environments (i.e., simulated seawater, ultrapure water, and a waterless (air) condition) was carried out. Data on the changes in physical and chemical properties were collected. The FTIR spectra showed that hydroxyl groups and carbonyl groups developed in three types of weathered plastic pellets under the air and ultrapure water environmental conditions after 3months of UV irradiation, while only carbonyl groups were found in plastic pellets in the simulated seawater environment. In contrast, the Raman spectra showed no significant changes in the weathered plastic pellets, but there were different intensities of characteristic peaks after exposure to UV irradiation. In addition, SEM images illustrated that granular oxidation, cracks and flakes were common patterns during degradation, and the plastic pellets in the three different environments experienced different levels of chemical weathering. We suggest that further studies on the degradation processes of plastic debris are needed to predict the fate of plastic debris in the environment. PMID- 29454215 TI - Effect-based trigger values for in vitro and in vivo bioassays performed on surface water extracts supporting the environmental quality standards (EQS) of the European Water Framework Directive. AB - Effect-based methods including cell-based bioassays, reporter gene assays and whole-organism assays have been applied for decades in water quality monitoring and testing of enriched solid-phase extracts. There is no common EU-wide agreement on what level of bioassay response in water extracts is acceptable. At present, bioassay results are only benchmarked against each other but not against a consented measure of chemical water quality. The EU environmental quality standards (EQS) differentiate between acceptable and unacceptable surface water concentrations for individual chemicals but cannot capture the thousands of chemicals in water and their biological action as mixtures. We developed a method that reads across from existing EQS and includes additional mixture considerations with the goal that the derived effect-based trigger values (EBT) indicate acceptable risk for complex mixtures as they occur in surface water. Advantages and limitations of various approaches to read across from EQS are discussed and distilled to an algorithm that translates EQS into their corresponding bioanalytical equivalent concentrations (BEQ). The proposed EBT derivation method was applied to 48 in vitro bioassays with 32 of them having sufficient information to yield preliminary EBTs. To assess the practicability and robustness of the proposed approach, we compared the tentative EBTs with observed environmental effects. The proposed method only gives guidance on how to derive EBTs but does not propose final EBTs for implementation. The EBTs for some bioassays such as those for estrogenicity are already mature and could be implemented into regulation in the near future, while for others it will still take a few iterations until we can be confident of the power of the proposed EBTs to differentiate good from poor water quality with respect to chemical contamination. PMID- 29454216 TI - Non-linear effects of mean temperature and relative humidity on dengue incidence in Guangzhou, China. AB - BACKGROUND: Dengue fever is an important infectious disease in Guangzhou, China; previous studies on the effects of weather factors on the incidence of dengue fever did not consider the linearity of the associations. METHODS: This study evaluated the effects of daily mean temperature, relative humidity and rainfall on the incidence of dengue fever. A generalized additive model with splines smoothing function was performed to examine the effects of daily mean, minimum and maximum temperatures, relative humidity and rainfall on incidence of dengue fever during 2006-2014. RESULTS: Our analysis detected a non-linear effect of mean, minimum and maximum temperatures and relative humidity on dengue fever with the thresholds at 28 degrees C, 23 degrees C and 32 degrees C for daily mean, minimum and maximum temperatures, 76% for relative humidity, respectively. Below the thresholds, there was a significant positive effect, the excess risk in dengue fever for each 1 degrees C in the mean temperature at lag7-14days was 10.21%, (95% CI: 6.62% to 13.92%), 7.10% (95% CI: 4.99%, 9.26%) for 1 degrees C increase in daily minimum temperature in lag 11days, and 2.27% (95% CI: 0.84%, 3.72%) for 1 degrees C increase in daily maximum temperature in lag 10days; and each 1% increase in relative humidity of lag7-14days was associated with 1.95% (95% CI: 1.21% to 2.69%) in risk of dengue fever. CONCLUSIONS: Future prevention and control measures and epidemiology studies on dengue fever should consider these weather factors based on their exposure-response relationship. PMID- 29454217 TI - Morphologies and elemental compositions of local biomass burning particles at urban and glacier sites in southeastern Tibetan Plateau: Results from an expedition in 2010. AB - Many studies indicate that the atmospheric environment over the southern part of the Tibetan Plateau is influenced by aged biomass burning particles that are transported over long distances from South Asia. However, our knowledge of the particles emitted locally (within the plateau region) is poor. We collected aerosol particles at four urban sites and one remote glacier site during a scientific expedition to the southeastern Tibetan Plateau in spring 2010. Weather and backward trajectory analyses indicated that the particles we collected were more likely dominated by particles emitted within the plateau. The particles were examined using an electron microscope and identified according to their sizes, shapes and elemental compositions. At three urban sites where the anthropogenic particles were produced mainly by the burning of firewood, soot aggregates were in the majority and made up >40% of the particles by number. At Lhasa, the largest city on the Tibetan Plateau, tar balls and mineral particles were also frequently observed because of the use of coal and natural gas, in addition to biofuel. In contrast, at the glacier site, large numbers of chain-like soot aggregates (~25% by number) were noted. The morphologies of these aggregates were similar to those of freshly emitted ones at the urban sites; moreover, physically or chemically processed ageing was rarely confirmed. These limited observations suggest that the biomass burning particles age slowly in the cold, dry plateau air. Anthropogenic particles emitted locally within the elevated plateau region may thus affect the environment within glaciated areas in Tibet differently than anthropogenic particles transported from South Asia. PMID- 29454218 TI - Atmospheric pattern of volatile organochlorine compounds and hexachlorobenzene in the surroundings of a chlor-alkali plant. AB - The outdoor atmospheric distributions of chlorinated volatile organic compounds (VOCs) from locations receiving the emissions of a chlor-alkali plant have been studied. Trichloroethylene and tetrachloroethylene (medians 2.4 MUg/m3 and 1.7 MUg/m3, respectively) were the most abundant compounds, which was in accordance with the production processes from these installations. The concentrations of trichlorofluoromethane, median 1.6 MUg/m3, are rather similar to the average levels described in general in the troposphere and cannot be attributed to this specific source. Several by-products involving dichloroacetylene, carbon tetrachloride, hexachloroethane, hexachlorobutadiene, trans-1H-pentachloro-1,3 butadiene, 2H-pentachloro-1,3-butadiene, cis-1H-pentachloro-1,3-butadiene, tetrachloro- and trichloro-butadienes and hexachlorobenzene were also identified. Some of these compounds, e.g. carbon tetrachloride, chloroform and tetrachloroethane, could also have been manufactured during some periods. The occurrence of these manufactured compounds and by-products in the atmosphere could also reflect, at least in part, volatilization during the extraction of previously discharged chlor-alkali residues developed within the environmental restoration program of the Flix water reservoir. In this respect, the tri-, tetra and pentachloro-1,3-butadienes could also originate from microbial transformation in the solid deposits accumulated in the water reservoir which were volatilized after extraction. Among all identified VOCs, trichloroethylene showed the highest health risks considering the measured airborne concentrations and the WHO and USEPA recommendations. PMID- 29454219 TI - Reading skill related to left ventral occipitotemporal cortex during a phonological awareness task in 5-6-year old children. AB - The left ventral occipitotemporal cortex (vOT) is important in visual word recognition. Studies have shown that the left vOT is generally observed to be involved in spoken language processing in skilled readers, suggesting automatic access to corresponding orthographic information. However, little is known about where and how the left vOT is involved in the spoken language processing of young children with emerging reading ability. In order to answer this question, we examined the relation of reading ability in 5-6-year-old kindergarteners to the activation of vOT during an auditory phonological awareness task. Two experimental conditions: onset word pairs that shared the first phoneme and rhyme word pairs that shared the final biphone/triphone, were compared to allow a measurement of vOT's activation to small (i.e., onsets) and large grain sizes (i.e., rhymes). We found that higher reading ability was associated with better accuracy of the onset, but not the rhyme, condition. In addition, higher reading ability was only associated with greater sensitivity in the posterior left vOT for the contrast of the onset versus rhyme condition. These results suggest that acquisition of reading results in greater specialization of the posterior vOT to smaller rather than larger grain sizes in young children. PMID- 29454220 TI - Early life sexual abuse is associated with increased suicide attempts: An update meta-analysis. AB - Suicide is an emerging, yet preventable global health issue associated with significant mortality. Identification of underlying risk factors and antecedents may inform preventive strategies and interventions. This study serves to provide an updated meta-analysis examining the extent of association of early life sexual abuse with suicide attempts. Using the keywords [early abuse OR childhood abuse OR sexual OR rape OR molest* OR violence OR trauma OR PTSD] AND [suicid* OR premature OR unnatural OR deceased OR died OR mortality], a preliminary search on the PubMed, Ovid, PsychINFO, Web of Science and Google Scholar databases yielded 12,874 papers published in English between 1-Jan-1988 and 1-June-2017. Of these, only 47 studies were included in the final meta-analysis. The 47 studies (25 cross-sectional, 14 cohort, 6 case-control and 2 twin studies) contained a total of 151,476 subjects. Random-effects meta-analysis found early life sexual abuse to be a significant risk factor for suicide attempts, compared to baseline population (pooled OR 1.89, 95% CI: 1.66 to 2.12, p < 0.001). Subgroup analyses of cross-sectional and longitudinal studies showed similar findings of increased risk as they yielded ORs of 1.98 (95% CI: 1.70 to 2.25, p < 0.001) and 1.65 (95% CI: 1.37 to 1.93, p < 0.001), respectively. In both cross-sectional and longitudinal studies, childhood sexual abuse was consistently associated with increased risk of suicide attempts. The findings of the present study provide strong grounds for funding public policy planning and interventions to prevent sexual abuse and support its victims. Areas for future research should include preventive and treatment strategies and factors promoting resilience following childhood sexual abuse. Future research on the subject should have more robust controls and explore the differential effects of gender and intra-versus extra familial sexual abuse. PMID- 29454222 TI - Obesity, dyslipidemia and brain age in first-episode psychosis. AB - INTRODUCTION: Obesity and dyslipidemia may negatively affect brain health and are frequent medical comorbidities of schizophrenia and related disorders. Despite the high burden of metabolic disorders, little is known about their effects on brain structure in psychosis. We investigated, whether obesity or dyslipidemia contributed to brain alterations in first-episode psychosis (FEP). METHODS: 120 participants with FEP, who were undergoing their first psychiatric hospitalization, had <24 months of untreated psychosis and were 18-35 years old and 114 controls within the same age range participated in the study. We acquired 3T brain structural MRI, fasting lipids and body mass index. We used machine learning trained on an independent sample of 504 controls to estimate the individual brain age of study participants and calculated the BrainAGE score by subtracting the chronological from the estimated brain age. RESULTS: In a multiple regression model, the diagnosis of FEP (B = 1.15, SE B = 0.31, p < 0.001) and obesity/overweight (B = 0.92, SE B = 0.35, p = 0.008) were each additively associated with BrainAGE scores (R2 = 0.22, F(3, 230) = 21.92, p < 0.001). BrainAGE scores were highest in participants with FEP and obesity/overweight (3.83 years, 95%CI = 2.35-5.31) and lowest in normal weight controls (-0.27 years, 95%CI = -1.22-0.69). LDL-cholesterol, HDL-cholesterol or triglycerides were not associated with BrainAGE scores. CONCLUSIONS: Overweight/obesity may be an independent risk factor for diffuse brain alterations manifesting as advanced brain age already early in the course of psychosis. These findings raise the possibility that targeting metabolic health and intervening already at the level of overweight/obesity could slow brain ageing in FEP. PMID- 29454221 TI - 13C-phenylalanine breath test and serum biopterin in schizophrenia, bipolar disorder and major depressive disorder. AB - Phenylalanine is required for the synthesis of the neurotransmitters dopamine, noradrenaline, and adrenaline. The rate-limiting step for phenylalanine metabolism is catalyzed by phenylalanine hydroxylase (PAH) and its cofactor tetrahydrobiopterin. We aimed to detect altered phenylalanine metabolism in major psychiatric disorders using the l-[1-13C]phenylalanine breath test (13C-PBT) and serum biopterin levels. We also investigated association of PAH mutations with schizophrenia and phenylalanine metabolism. 13C-phenylalanine (100 mg) was orally administered, and the breath 13CO2/12CO2 ratio was monitored for 120 min in four groups: 103 patients with schizophrenia (DSM-IV), 39 with bipolar disorder, 116 with major depressive disorder (MDD), and 241 healthy controls. Serum biopterin levels were measured by high performance liquid chromatography. Mutation screening of PAH exons was performed by direct sequencing in 46 schizophrenia patients. Association analysis was performed using six tag single nucleotide polymorphisms and the PAH Arg53His mutation by TaqMan assays in 616 schizophrenia patients and 1194 healthy controls. Analyses of covariance controlling for age, sex, and body weight showed that the index for the amount of exhaled 13CO2 was significantly lower in the schizophrenia group than in the other three groups (all p < 0.05). Biopterin levels in schizophrenia and MDD were significantly lower than those in controls. Biopterin levels correlated with 13C-PBT indices in controls. PAH polymorphisms were not associated with schizophrenia or 13C-PBT indices. 13C-PBT revealed reduced phenylalanine metabolism in schizophrenia, though we obtained no evidence of involvement of PAH polymorphism. Serum biopterin levels were lower in schizophrenia and MDD, warranting further investigation. PMID- 29454223 TI - Attention as the 'glue' for object integration in parietal extinction. AB - Patients with unilateral, parietal brain damage frequently show visual extinction, which manifests in a failure to identify contralesional stimuli when presented simultaneously with other, ipsilesional stimuli (but full awareness for single stimulus presentations). Extinction reflects an impairment of spatial selective attention, leaving basic preattentive processing unaffected. For instance, access to bilaterally grouped objects is usually spared in extinction, suggesting that grouping occurs at a stage preceding (in the patients: abnormally biased) spatial-attentional selection. Here, we reinvestigated this notion by comparing (largely between participants, but also within a single-case participant) conditions with objects that varied in their dominant direction of grouping: from the attended to the non-attended hemifield (data from Conci et al., 2009) versus from the non-attended to the attended hemifield (new data). We observe complete absence of extinction when shape completion extended from the attended hemifield. By contrast, extinction was not diminished when object groupings propagate from the unattended hemifield. Moreover, we found the individual severity of the attentional impairment (assessed by a standard "inattention" test) to be directly related to the degree of completion in the unattended hemifield. This pattern indicates that grouping can overcome visual extinction only when object integration departs from the attended visual field, implying, contrary to many previous accounts, that attention is crucial for grouping to be initiated. PMID- 29454224 TI - The consonant/vowel pattern determines the structure of orthographic representations in the left fusiform gyrus. AB - Recent findings demonstrated readers' sensitivity to the distinction between consonant and vowel letters. Especially, the way consonants and vowels are organised within written words determines their perceptual structure. The present work attempted to overcome two limitations of previous studies by examining the neurophysiological correlates of this perceptual structure through magnetoencephalography (MEG). One aim was to establish that the extraction of vowel-centred units takes place during early stages of processing. The second objective was to confirm that the vowel-centred structure pertains to the word recognition system and may constitute one level in a hierarchy of neural detectors coding orthographic strings. Participants performed a cross-case matching task in which they had to judge pairs of stimuli as identical or different. The critical manipulation concerned pairs obtained by transposing two letters, so that the vowel-centred structure was either preserved (FOUVERT fovuert, two vowel letter clusters) or modified (BOUVRET-bovuret). Mismatches were detected faster when the structure was modified. This effect was associated with a significant difference in evoked neuromagnetic fields extending from 129 to 239 msec after the stimulation. Source localization indicated a significant effect in the visual word form area around 200 msec. The results confirm the hypothesis that the vowel-centred structure is extracted during the early phases of letter string processing and that it is encoded in left fusiform regions devoted to visual word recognition. PMID- 29454225 TI - Low power lasers on genomic stability. AB - Exposure of cells to genotoxic agents causes modifications in DNA, resulting to alterations in the genome. To reduce genomic instability, cells have DNA damage responses in which DNA repair proteins remove these lesions. Excessive free radicals cause DNA damages, repaired by base excision repair and nucleotide excision repair pathways. When non-oxidative lesions occur, genomic stability is maintained through checkpoints in which the cell cycle stops and DNA repair occurs. Telomere shortening is related to the development of various diseases, such as cancer. Low power lasers are used for treatment of a number of diseases, but they are also suggested to cause DNA damages at sub-lethal levels and alter transcript levels from DNA repair genes. This review focuses on genomic and telomere stabilization modulation as possible targets to improve therapeutic protocols based on low power lasers. Several studies have been carried out to evaluate the laser-induced effects on genome and telomere stabilization suggesting that exposure to these lasers modulates DNA repair mechanisms, telomere maintenance and genomic stabilization. Although the mechanisms are not well understood yet, low power lasers could be effective against DNA harmful agents by induction of DNA repair mechanisms and modulation of telomere maintenance and genomic stability. PMID- 29454226 TI - Dysphagia and laryngeal pathology in post-surgical cardiothoracic patients. AB - PURPOSE: Cardiothoracic surgery is known to result in dysphagia and laryngeal injury. While prevalence has been explored, extent, trajectory and longevity of symptoms are poorly understood. This retrospective, observational study explored dysphagia and laryngeal injury in patients following cardiothoracic surgery referred for instrumental swallowing assessment. METHODS: Clinical notes and endoscopic recordings of 106 patients (age range 18-87yrs; mean 63yrs; SD 15yrs) (including 190 endoscopes) at one large tertiary centre were reviewed by two speech-language pathologists and a laryngologist. Standardized measures of laryngeal anatomy and physiology, New Zealand Secretion Scale, Penetration Aspiration scale and Yale Residue Scale were rated. RESULTS: Prevalence of abnormality included 39% silent aspiration, 65% laryngeal edema and 61% vocal paralysis. The incidence of pneumonia was 36% with a post-operative stroke rate of 14%. Forty percent of patients were receiving a standard diet by discharge from acute care; while, 24% continued to require enteral feeding and 8% received laryngeal surgery within twelve months of discharge. Vocal fold motion impairment was significantly associated with ventilation time and tracheostomy tube duration (p<.05). CONCLUSION: Early endoscopic assessment for identification of dysphagia and laryngeal injury in patients following cardiothoracic surgery may allow early management and prevention of secondary complications.

AB - OBJECTIVE: To investigate the effects of l-Carnitine on neuron specific enolase (NSE) as a marker of inflammation in patients with traumatic brain injury (TBI). METHODS: Forty patients with severe TBI were randomized into 2 groups. The (LCA-) group received standard treatment with placebo while the (LCA+) group received l Carnitine 2g/day for one week. NSE was measured on days 1, 3 and 7 after the initiation of the study. Neurocognitive and neurobehavioral disorders were recorded on the first and third months. RESULTS: Neurocognitive function and NSE significantly improved within one week in both groups. Patient mortality was similar in LCA+ and LCA- groups (P value: 0.76). Brain edema was present in 7 patients in LCA+ group and 13 patients in LCA-group (P value: 0.044). While there was no difference in NSE levels between the two groups. Neurological function was preserved in the LCA+ group with an exception of attention deficit, which was frequent in the LCA+ group. CONCLUSION: We concluded that despite improvements in neurobehavioral function and the degree of cerebral edema, 7-days of treatment with l-Carnitine failed to reduce serum NSE levels or improve mortality rate at 90days in patients with TBI.

AB - INTRODUCTION: Obturator internus muscle (OIM) abscess is a rare condition, usually affecting children after trauma or muscular effort. Blood cultures always yield positive findings, with Staphylococcus aureus being the most common culprit. There are few reports in adults. PRESENTATION OF CASE: We report a case of OIM abscess in an adult. A 24-year-old male was admitted to our hospital because of right hip pain and fever. He was diagnosed with OIM abscess, and methicillin-resistant Staphylococcus aureus (MRSA) was detected on bacterial examination. The patient was successfully treated with a surgical drainage procedure and antibiotics. DISCUSSION: There are only five reported cases of OIM abscess in adults. The patient had no history of recent hip trauma, but had intractable acronyx of the right great toe, which was being treated for 2 years. MRSA was also detected from cultures of samples obtained from the toe. A toe infection can lead to bacteremia. CONCLUSION: In conclusion, we report the first case of OIM abscess in an adult caused by MRSA. Surgical drainage, debridement, and systemic antibiotic treatment were administered, resulting in a successful outcome. PMID- 29454229 TI - Pancreatic cancer presenting as colonic disease. A rare case report. AB - INTRODUCTION: Pancreatic cancer is the fourth major cause of cancer-related deaths. About 50% of the patients are diagnosed with advanced disease. Metastatic disease to the colon is a very rare entity with only 5 cases described in english literature. CASE PRESENTATION: Male, 60 years-old, presents to a surgical consult with the diagnosis of an adenocarcinoma of the sigmoid colon. The physical exam revealed a periumbilical nodule with suspicious features. The staging CT-scan showed a mass in the tail of the pancreas involving the spleen and left kidney, thickening of the sigmoid colon, multiple mesenteric masses and trabecular changes in the ischium, suggesting metastatic disease. The case was discussed by a multidisciplinary team and it was decided to do a biopsy of the umbilical nodule and review the specimen obtained in colonoscopy. Pathological analysis revealed a metastasis from pancreatic adenocarcinoma. The patient was proposed to start palliative chemotherapy for metastatic pancreatic cancer. After 2 cycles of FOLFOX the patient was admitted in the OR with a perforation of the sigmoid mass. He was submitted to a sigmoidectomy with end colostomy, with discharge at the 5th postoperative day. Pathological analysis of the specimen confirmed the pancreatic origin of the tumor. Patient proceeded with palliative treatment, with death 9 months after the diagnosis. DISCUSSION: Pancreatic metastasis to the colon is a very rare entity. Care should be taken when addressing these patients. CONCLUSION: Although rare, a sigmoid tumor in a patient with known pancreatic adenocarcinoma must raise the suspicion of metastasis.

AB - The aim of this study was to investigate muscle activity in the infraspinatus and posterior deltoid and infraspinatus muscle thickness during a prone external rotation (PER) exercise using pressure biofeedback. Fifteen healthy men participated in this study, performing PER exercise with pressure biofeedback under four conditions (comfortable, 2 mm Hg, 4 mm Hg, and 8 mm Hg). Surface electromyography (EMG) was used to monitor infraspinatus and posterior deltoid muscle activity, and ultrasonography was used to collect infraspinatus muscle thickness data. Infraspinatus activity and muscle thickness were greatest at 2 mm Hg pressure feedback, and both measures were significantly different from those under other pressure feedback conditions (p < 0.05). In contrast, posterior deltoid activity was lower at 2 mm Hg. However, there was no significant difference between any of the four pressure feedback conditions. These findings suggest that PER exercise with pressure biofeedback, particularly at 2 mm Hg, is effective in selectively activating the infraspinatus muscle. PMID- 29454231 TI - Influence of heading perception in the control of posture. AB - The optic flow visual input directly influences the postural control. The aim of the present study was to examine the relationship between visually induced heading perception and postural stability, using optic flow stimulation. The dots were accelerated to simulate a heading direction to the left or to the right of the vertical midline. The participants were instructed to indicate the perceived optic flow direction by making a saccade to the simulated heading direction. We simultaneously acquired electromyographyc and center of pressure (COP) signals. We analysed the postural sway during three different epochs: (i) the first 500 ms after the stimulus onset, (ii) 500 ms before saccade onset, epoch in which the perception is achieved and, (iii) 500 ms after saccade onset. Participants exhibited a greater postural instability before the saccade, when the perception of heading was achieved, and the sway increased further after the saccade. These results indicate that the conscious representation of the self-motion affects the neural control of posture more than the mere visual motion, producing more instability when visual signals are contrasting with eye movements. It could be that part of these effects are due to the interactions between gaze shift and optic flow.

AB - Chub (Squalius cephalus) specimens were collected in Korenita River seven months after spillover from the waste water of antimony mine tailing pond and compared with chub living in Kruscica reservoir (intended for water supply) and Meduvrsje reservoir (influenced by intense emission of industrial, urban and rural wastewater). Concentrations of 15 elements (Al, As, B, Ba, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Si, Sr, Zn) were determined in muscle, liver and gills of chub by inductively coupled plasma optical spectrometry (ICP-OES) and histopathological alterations in liver and gills were assessed. Chub specimens from Korenita River had higher concentrations of As, Ba and Pb in all three investigated tissues as well as higher total histopathological index values than chub from reservoirs. Specimens from Meduvrsje reservoir were characterized by higher values for concentrations of Cu and Si in muscle tissue and higher values for regressive histopathological alterations in gills. Individuals of chub from Kruscica reservoir had the highest concentrations of Fe in liver, Hg in muscle and Sr and Zn in muscle while gills had the lowest value of total histopathological index. The results from the present study showed higher level of histopathological alterations as a result of mine tailing accident. As a result of mixed contamination on the Meduvrsje site, histopathological index values of gills were in line with the index value from Korenita River. Increased values for Fe and Sr in chub tissue from Kruscica reservoir could be explained by geological structure of the site which is characterized by magmatic rock rich in Cu, Fe and Ni as well as dominant carbonate sediment complex of marine origin with increased level of Sr. PMID- 29454233 TI - Combined effect of water inundation and heavy metals on the photosynthesis and physiology of Spartina alterniflora. AB - The frequency and duration of tidal flooding significantly influence the bioavailability of heavy metals (HMs) in sediment and hence exert toxicological effects on coastal wetland plants. In this study, the combined effects of different water inundation times (3, 6, 9, and 12 h) and HMs (Cu, Zn, Pb, and Cr) on the photosynthesis and physiology of Spartina alterniflora were investigated under greenhouse conditions. Results showed that S. alterniflora was somehow tolerant to the combined HMs treatments, and only the highest level of HM treatment decreased leaf chlorophyll content. Furthermore, the plants did not show any signs of victimization. Different times of water inundation with HMs did not exert any significant effect on the malonaldehyde (MDA) and chlorophyll contents in the leaves of S. alterniflora at day 20. Prolonged water inundation time at day 60 significantly reduced leaf chlorophyll content with the decrease in leaf photosynthetic rate, which was accompanied by a significant increase in the intercellular concentration of CO2. At day 60, abscisic acid dose-dependently increased along the different water inundation times, indicating that this phytohormone is involved in plant responses to flooding stress. Peroxidase (POD), superoxide dismutase (SOD), and ascorbate peroxidase (APX), showed different responses to the combined treatment of water inundation and HMs at different times. At day 20, the long duration of water inundation and HMs treatments (9 h+HMs and/or 12 h+HMs) significantly increased enzyme activity in the leaves compared with the control group (6 h). At day 60, the POD and SOD activities in the leaves of S. alterniflora decreased with prolonged water inundation time, and root APX activity significantly decreased compared with the 6 h water inundation treatment. PMID- 29454234 TI - Diarylheptanoid from rhizomes of Curcuma kwangsiensis (DCK) inhibited imiquimod induced dendritic cells activation and Th1/Th17 differentiation. AB - BACKGROUND AND OBJECT: Dendritic cells (DCs) are critical for initiating the activation and differentiation of T cells in inflammatory diseases including psoriasis. Curcuma kwangsiensis S.G. Lee & C.F. Liang is a herb for treating psoriasis and we previously found Diarylheptanoid from rhizomes of Curcuma kwangsiensis (DCK) inhibited keratinocytes proliferation. However, it is unknown whether DCK influences DC functions. Thus we aimed to explore whether DCK affect the major immunological functions of DCs. MATERIALS AND METHODS: Primary DCs derived from mouse bone marrow cells and spleen were used for examining their general immunological functions, and OVA-specific T cells from OT-II mice were used for examining the DC-mediated T-helper (Th) 1 and Th17 cells differentiation and effect. RESULTS: We demonstrated DCK suppressed DC uptake of FITC-labeled ovalbumin (OVA) and DC maturation characterized by decreased MHCII, CD80 and CD86 following imiquimod (IMQ) stimulation. DCK also reduced DC expression of the lymphoid-homing chemokine receptor CCR7, and DC migration towards CCL21, the ligand for CCR7. Importantly, DCK significantly reduced the production of proinflammatory cytokines including IL-12, IL-6 and IL-1beta by IMQ-stimulated DCs. Moreover, in the coculture of OVA323-339 peptide-pulsed DCs and OVA-specific T cells from OT-II mice, DCK significantly inhibited T cell proliferation and the differentiation of Th1 and Th17 cells. Furthermore, DCK treatment greatly reduced phosphorylation of p65-associated cell signaling pathway in IMQ-stimulated DCs. CONCLUSION: These data together demonstrate a potential role of DCK in suppressing the biological function of DCs, and provide a possible mechanism for understanding the effects of herb Curcuma kwangsiensis in treating psoriasis. PMID- 29454235 TI - Donor and recipient P450 gene polymorphisms influence individual pharmacological effects of tacrolimus in Chinese liver transplantation patients. AB - The immunosuppressant drug tacrolimus (Tac) used for the prevention of immunological rejection is a metabolic substrate of cytochrome P450 enzymes. This study was designed to evaluate the short-term and long-term potential influence of single-nucleotide polymorphisms (SNPs) in CYP450 genes of liver transplant (LT) recipients as well as the donors on individual pharmacological effects of Tac and to guide individualized-medication from the perspective of pharmacogenomics. Twenty-one SNPs of the CYP450 gene were genotyped for both recipients and donors in 373 LT patients receiving Tac-based immunosuppressants. The Tac concentration/dosage ratio (C/D) was evaluated from the initial medication until one year after LT. The C/D ratio was significantly higher when the donor and/or recipient genotype of CYP3A5 rs776746 was G/G or rs15524 was T/T or rs4646450 was C/C all through one year after transplantation. Comparing the effect of donor gene variants of rs776746, rs15524, and rs4646450 on Tac C/D ratios with the recipients, statistically significant differences were found between the donor T/T group and the recipient T/T group in rs15524 at 1 month and 6 months, and at 6 months, the donor C/C group differed from the recipient C/C group in rs4646450. In conclusion, rs776746, rs15524, and rs4646450 of CYP3A5 had a significant influence on Tac pharmacological effects for both the initial use and long-term use. The donor liver genotype and the recipient intestine genotype contribute almost equally in the short-term, but the donor genotype had a greater effect than the recipient genotype at 6 months. Personalized Tac treatment after LT should be based on the CYP3A5 genotype. PMID- 29454237 TI - Liposomes of dimeric artesunate phospholipid: A combination of dimerization and self-assembly to combat malaria. AB - Artemisinin and its derivatives are highly effective drugs in the treatment of P. falciparum malaria. However, their clinical applications face challenges because of short half-life, poor bioavailability and growing drug resistance. In this article, novel dimeric artesunate phospholipid (Di-ART-GPC) based liposomes were developed by combination of dimerization and self-assembly to address these shortcomings. Firstly, Di-ART-GPC conjugate was synthesized by a facile esterification of artesunate (ART) and glycerophosphorylcholine (GPC) and confirmed by MS, 1H NMR and 13C NMR. The conjugate was then assembled to form liposomes without excipient by thin film hydration method. The assembled Di-ART GPC liposomes have typical multilamellar vesicle structure with bilayer morphology as determined by transmission electron microscopy (TEM) and cryogenic electron microscopy (cryo-EM). Moreover, the liposomes displayed an average hydrodynamic diameter of 190 nm and negative zeta potential at -20.35 mV as determined by Zetasizer. The loading capacity of ART was calculated approximately 77.6% by weight with this liposomal formulation after a simple calculation. In vitro drug release and degradation results showed that the Di-ART-GPC liposomes were stable in neutral physiological conditions but effectively degraded to release parent ART in simulated weakly acidic microenvironment. In vivo pharmacokinetics study revealed that Di-ART-GPC liposomes and conjugate have longer retention half-life in bloodstream. Importantly, Di-ART-GPC liposomes (IC50 0.39 nM) and the conjugate (IC50 1.90 nM) demonstrated excellent in vitro antiplasmodial activities without causing hemolysis of erythrocytes, which were superior to free ART (IC50 5.17 nM) and conventional ART-loaded liposomes (IC50 3.13 nM). Furthermore, the assembled liposomes resulted in enhanced parasites killing in P. berghei-infected mice in vivo with delayed recrudescence and improved survivability, compared to free ART administration. Based on these encouraging results, Di-ART-GPC liposomal formulation could be a replacement to parent ART in clinical malarial therapy after thorough investigation. PMID- 29454236 TI - STINGel: Controlled release of a cyclic dinucleotide for enhanced cancer immunotherapy. AB - Recent advancements in the field of immunotherapy have yielded encouraging results for the treatment of advanced cancers. Cyclic dinucleotides (CDNs) are a powerful new class of immunotherapy drugs known as STING (Stimulator of Interferon Genes) agonists, currently in clinical trials. However, previous studies of CDNs in murine cancer models have required multiple injections, and improve survival only in relatively nonaggressive tumor models. Therefore, we sought to improve the efficacy of CDN immunotherapy by developing a novel biomaterial we call "STINGel." STINGel is an injectable peptide hydrogel that localizes and provides controlled release of CDN delivery, showing an 8-fold slower release rate compared to a standard collagen hydrogel. The carrier hydrogel is a positively charged, MultiDomain Peptide (MDP) which self-assembles to form a nanofibrous matrix and is easily delivered by syringe. The highly localized delivery of CDN from this nanostructured biomaterial affects the local histological response in a subcutaneous model, and dramatically improves overall survival in a challenging murine model of head and neck cancer compared to CDN alone or CDN delivered from a collagen hydrogel. This study demonstrates the feasibility of biomaterial-based immunotherapy platforms like STINGel as strategies for increasing the efficacy of CDN immunotherapies. PMID- 29454238 TI - Transformations of dissolved organic matter induced by UV photolysis, Hydroxyl radicals, chlorine radicals, and sulfate radicals in aqueous-phase UV-Based advanced oxidation processes. AB - Considering the increasing identification of trace organic contaminants in natural aquatic environments, the removal of trace organic contaminants from water or wastewater discharge is an urgent task. Ultraviolet (UV) and UV-based advanced oxidation processes (AOPs), such as UV/hydrogen peroxide (UV/H2O2), UV/free chlorine and UV/persulfate, are attractive and promising approaches for the removal of these contaminants due to the high reactivity of active radical species produced in these UV-AOPs with a wide variety of organic contaminants. However, the removal efficiency of trace contaminants is greatly affected by the presence of background dissolved organic matter (DOM). In this study, we use ultrahigh resolution mass spectrometry to evaluate the transformation of a standard Suwanee River fulvic acid DOM isolate in UV photolysis and UV-AOPs. The use of probe compounds allows for the determination of the steady-state concentrations of active radical species in each UV-AOP. The changes in the H/C and O/C elemental ratios, double bond equivalents, and the low-molecular-weight transformation product concentrations of organic acids reveal that different DOM transformation patterns are induced by each UV-AOP. By comparison with the known reactivities of each radical species with specific organic compounds, we mechanistically and systematically elucidate the molecular-level DOM transformation pathways induced by hydroxyl, chlorine, and sulfate radicals in UV AOPs. We find that there is a distinct transformation in the aliphatic components of DOM due to HO* in UV/H2O2 and UV/free chlorine. Cl* induced transformation of olefinic species is also observed in the UV/free chlorine system. Transformation of aromatic and olefinic moieties by SO4*- are the predominant pathways in the UV/persulfate system. PMID- 29454240 TI - Deterrent effects of demerit points and license sanctions on drivers' traffic law violations using a proportional hazard model. AB - Current traffic law enforcement places an emphasis on reducing accident risk from human factors such as drunk driving and speeding. Among the various strategies implemented, demerit points and license sanction systems have been widely used as punitive and educational measures. Limitations, however, exist in previous studies in terms of estimating the interaction effects of demerit points and license sanctions. To overcome such limitations, this work focused on identifying the interaction effects of demerit points and license sanctions on driver traffic violation behavior. The interaction deterrent effects were assessed by using a Cox's proportional hazard model to provide a more accurate and unbiased estimation. For this purpose, five years of driver conviction data was obtained from the Korea National Police Agency (KNPA). This data included personal characteristics, demerit point accumulation and license sanction status. The analysis showed that accumulated demerit points had specific deterrent effects. Additionally, license revocation showed consistent and significant deterrent effects, greater than those for suspension. Male drivers under their 30s holding a motorcycle license were identified as the most violation-prone driver group, suggesting that stricter testing for the acquisition of a motorcycle driver's license is needed. PMID- 29454239 TI - Phenol separation from phenol-laden saline wastewater by membrane aromatic recovery system-like membrane contactor using superhydrophobic/organophilic electrospun PDMS/PMMA membrane. AB - Phenol recovery from phenol-laden saline wastewater plays an important role in the waste reclamation and pollution control. A membrane aromatic recovery system like membrane contactor (MARS-like membrane contactor) was set up in this study using electrospun polydimethylsiloxane/polymethyl methacrylate (PDMS/PMMA) membrane with 0.0048 m2 effective area to separate phenol from saline wastewater. Phenol and water contact angles of 0 degrees and 162 degrees were achieved on this membrane surface simultaneously, indicating its potential in the separation of phenol and water-soluble salt. Feed solution (500 mL) of 0.90 L/h and receiving solution (500 mL) of 1.26 L/h were investigated to be the optimum conditions for phenol separation, which corresponds to the employed Reynolds number of 14.6 and 20.5. During 108-h continuous separation for feed solution (2.0 g/L phenol, 10.0 g/L NaCl) under room temperature (20 degrees C), 42.6% of phenol was recycled in receiving solution with a salt rejection of 99.95%. Meanwhile, the mean phenol mass transfer coefficient (Kov) was 6.7 * 10-7 m s-1. As a membrane-based process, though the permeated phenol increased with the increase of phenol concentration in feed solution, the phenol recovery ratio was determined by the membrane properties rather than the pollutant concentrations. Phenol was found to permeate this membrane via adsorption, diffusion and desorption, and therefore, the membrane fouling generated from pore blockage in other membrane separation processes was totally avoided. PMID- 29454241 TI - Frailty and life course violence: The international mobility in aging study. AB - OBJECTIVE: To estimate the prevalence of frailty in older adults in the IMIAS population, to examine associations between lifelong domestic violence and frailty and possible pathways to explain these associations. METHODS: A cross sectional study with 2002 men and women in the International Mobility in Aging Study, aged between 65 and 74 years old living in five cities of Tirana (Albania), Natal (Brazil), Kingston and Saint-Hyacinthe (Canada), and Manizales (Colombia). Domestic physical and psychological violence by family and intimate partner was assessed by the Hurt, Insult, Threaten and Scream (HITS) scale. Fried's phenotype was adopted to define frailty. Logistic regressions were fitted to estimate between frailty and lifelong violence. Mediation analyses using the Preacher and Hayes method was used to examine potential health pathways. RESULTS: Frailty prevalence varies across cities, being lowest in Saint-Hyacinthe and Kingston, and highest in women in Natal. Women had a higher prevalence in Tirana and Natal. Adjusting for age, sex, education and research city, those reporting childhood physical abuse (CPA) had higher odds of frailty (OR = 1.68; 95% CI: 1.01; 2.78); those who had been exposed to psychological violence by their intimate partner had also higher odds of frailty (OR = 2.07; 95% CI: 1.37; 3.12). CPA effect on frailty was totally mediated by chronic conditions and depression symptoms. Effects of psychological violence by intimate partner were partially mediated by chronic conditions and depression symptoms. CONCLUSIONS: Childhood physical abuse and psychological violence during adulthood leave marks on life trajectory, being conducive to adverse health outcomes and frailty in old age. PMID- 29454242 TI - Making space work: Staff socio-spatial practices in a paediatric outpatient department. AB - Studies of the characteristics of therapeutic landscapes have become common in medical geography. However, there is limited analysis of how therapeutic landscapes are produced. Based upon the qualitative theoretical thematic analysis of focus group data, this study examined the spatial work carried out by healthcare practitioners in a paediatric outpatients' department, turning unsatisfactory space into a therapeutic place. The study highlights the spatial strategies employed by staff to mitigate socio-spatial deficiencies in the healthcare environment. Staff perceived the task of making space work as an integral part of their duty of care to patients and an important facet of their professional identity. This study concludes that many of the spatial aspects of health care practice are often taken for granted. However this may hide the crucial role that health professionals have in producing places that heal. PMID- 29454243 TI - Health inequities faced by Ethiopian migrant domestic workers in Lebanon. AB - This paper investigates the healthcare needs, access to healthcare, and healthcare strategies of Ethiopian migrant domestic workers (MDWs) in Lebanon, drawing on qualitative empirical research. The analysis focusses on four types of health care needs: minor illnesses, pregnancies, serious illnesses (such as cancer, tuberculosis or heart problems), and emergencies (due to accidents, suicide attempts or assaults). Predictably, access to healthcare is distinctly differentiated according to an MDW's status as a documented, freelancer, or undocumented worker. Drawing on the concepts of systemic health inequities and inter-personal racial discrimination, the paper provides evidence for inequitable access to healthcare experienced by Ethiopian women in Lebanon. I identify the specific forms of exclusion they experience and develop a matrix for analysis of systemic inequities in access to healthcare differentiated by migrant status. PMID- 29454244 TI - 'Keeping birth normal': Exploratory evaluation of a training package for midwives in an inner-city, alongside midwifery unit. AB - OBJECTIVES: to gain understanding about how participants perceived the value and effectiveness of 'Keeping Birth Normal' training, barriers to implementing it in an along-side midwifery unit, and how the training might be enhanced in future iterations. DESIGN: exploratory interpretive. SETTING: inner-city maternity service. PARTICIPANTS: 31 midwives attending a one-day training package on one of three occasions. METHODS: data were collected using semi-structured observation of the training, a short feedback form (23/31 participants), and focus groups (28/31 participants). Feedback form data were analysed using summative content analysis, following which all data sets were pooled and thematically analysed using a template agreed by the researchers. FINDINGS: We identified six themes contributing to the workshop's effectiveness as perceived by participants. Three related to the workshop design: (1) balanced content, (2) sharing stories and strategies and (3) 'less is more.' And three related to the workshop leaders: (4) inspiration and influence, (5) cultural safety and (6) managing expectations. Cultural focus on risk and low prioritisation of normal birth were identified as barriers to implementing evidence-based practice supporting normal birth. Building a community of practice and the role of consultant midwives were identified as potential opportunities. KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: a review of evidence, local statistics and practical skills using active educational approaches was important to this training. Two factors not directly related to content appeared equally important: catalysing a community of practice and the perceived power of workshop leaders to influence organisational systems limiting the agency of individual midwives. Cyclic, interactive training involving consultant midwives, senior midwives and the multidisciplinary team may be recommended to be most effective. PMID- 29454245 TI - Associations of household renovation materials and periods with childhood asthma, in China: A retrospective cohort study. AB - BACKGROUND: Childhood asthma is prevalent in China. However, there is a lack of evidence on whether household renovation, including the materials used and the periods, are associated with the disease. OBJECTIVES: To investigate the associations between household decoration materials and renovation periods, and childhood asthma and its related symptoms. METHODS: During 2010-2012, a retrospective cohort study was initiated in seven cities of China, and 40,010 children, aged 3-6 years, were recruited. Data on demographics, health status, and home decoration conditions were collected using a parent-administered questionnaire. Two-level (city-child) logistic regression analyses with adjusted odds ratios (AORs) and 95% confidence intervals (CIs) were performed to show the target associations. Sensitivity analysis was performed by stratifying data for children in the southern and northern cities. RESULTS: Children whose homes underwent renovation or the addition of new furniture within 1 year before pregnancy, during pregnancy, at age 0-1 year, and after age 1 year had significantly (p < 0.05) higher prevalence of childhood asthma and its related symptoms. The use of solid wood floors and wallpaper had significant associations (cement: AOR, 95% CI: 1.59, 1.17-2.17; lime: AOR, 95% CI: 1.31, 1.00-1.71) with an increased risk of lifetime asthma. Household renovation and the addition of new furniture during pregnancy had significant associations with lifetime asthma (renovation: AOR, 95% CI: 1.23, 1.01-1.51); lifetime wheeze (renovation: AOR, 95% CI: 1.21, 1.05-1.39; furniture: AOR, 95% CI: 1.24, 1.14-1.36), current wheeze (renovation: AOR, 95% CI, 1.21 1.05-1.40; furniture: AOR, 95% CI: 1.23, 1.12 1.34), and current dry cough (renovation: AOR, 95% CI: 1.41, 1.23-1.63; furniture: AOR, 95% CI: 1.28, 1.17-1.41). Similar associations were found between the addition of new furniture during early childhood and lifetime asthma and its related symptoms. Except for the association between lifetime wheeze and flooring materials, the studied associations were generally stronger among children from the northern cities. CONCLUSIONS: We confirmed that using cellulose based materials in home decoration and renovation, and adding new furniture during early childhood and pregnancy could be risk factors for childhood asthma. The association between household decoration during early childhood and childhood asthma may be stronger in the northern cities of China. PMID- 29454246 TI - Screening of physicochemical treatment processes for reducing toxicity of hair care products wastewaters. AB - Toxicity reduction in wastewaters from small hair care products manufacturing companies using coagulation/flocculation/sedimentation or flotation, membrane separation and powdered activated charcoal adsorption was evaluated. Raw wastewater composition varied widely within and especially between companies, but all exhibited high acute toxicity to Daphnia similis (EC(I)50; 48 h < 0.02 0.33%). Coagulation with aluminum sulfate and polyaluminum chloride aided by cationic or anionic polymers, as well as filtration on ultra (UF) and nanofiltration (NF) membranes efficiently removed turbidity (>99%) and oil and grease (>99%) and all treated samples exhibited similar dissolved organic matter contents. However, elimination of acute toxicity was only achieved after UF on submerged hollow fiber membrane, while other membrane modules (tubular UF and NF) produced filtrates with residual toxicities equal to or higher than the wastewater samples treated by coagulation processes. Adsorption removed up to 90% of the soluble COD remaining after coagulation or membrane processes, but did not eliminate acute toxicity, possibly because of the presence of activated charcoal or substances leached from it in the treated samples. The results indicate the need for further studies to develop treatment strategies that can guarantee non toxic effluents at costs compatible with those of the simple manufacturing processes used at small-scale cosmetics manufacturing plants. PMID- 29454247 TI - Tolerance and growth kinetics of bacteria isolated from gold and gemstone mining sites in response to heavy metal concentrations. AB - Response and growth kinetics of microbes in contaminated medium are useful indices for the screening and selection of tolerant species for eco-friendly bio augmentative remediation of polluted environments. In this study, the heavy metal (HM) tolerance, bioaccumulation and growth kinetics of seven bacterial strains isolated from mining sites to 10 HMs (Cd, Hg, Ni, Al, Cr, Pb, Cu, Fe, Mn and Zn) at varied concentrations (25-600 mgL-1) were investigated. The isolates were phylogenetically (16S rRNA gene) related to Lysinibacillus macroides, Achromobacter spanius, Bacillus kochii, B. cereus, Klebsiella pneumoniae, Pseudomonas mosselii and P. nitroreducens. Metal tolerance, effects on lag phase duration and growth rates were assessed using the 96-well micro-titre method. Furthermore, metal bioaccumulation and quantities within cells were determined by transmission electron microscopy and electron dispersive x-ray analyses. Tolerance to Ni, Pb, Fe and Mn occurred at highest concentrations tested. Growth rates increased with increasing Fe concentrations, but reduced significantly (p < .05) with increasing Zn, Cu, Hg, Cd and Al. Significantly higher (p < .05) growth rates (compared to controls) was found with some isolates in Hg (25 mgL-1), Ni (100 mgL-1), Cr (150 mgL-1), Mn (600 mgL-1), Pb (100 mgL-1), Fe (600 mgL-1) and Al (50 mgL-1). Lag phase urations were isolate- and heavy metal-specific, in direct proportion to concentrations. A. spanius accumulated the most Mn and Zn, while B. cereus accumulated the most Cu. Metals accumulated intra-cellularly without cell morphology distortions. The isolates' multi-metal tolerance, intra cellular metal bioaccumulation and growth kinetics suggest potentials for application in the synergetic biodegradation and bioremediation of polluted environments, especially HM-rich sites.

AB - Efficient stereocontrolled synthesis of ladyginoside A isolated from Ladyginia bucharica is described. The presented methodology bases on the beta-selective glycosylation to construct oleanate-3-O-beta-glycoside from selectively protected d-cellobiose comprising desired beta-linkage in carbohydrate unit. By using this procedure, dimethyl ester of ladyginoside A (1) (methyl oleanate 3-O-(beta-d glucopyranosyl)-(1 -> 4)-beta-d-glucuronide methyl ester) was obtained in 16% overall yield. Elaborated synthesis is also demonstrated as useful methodology en route to saponin 2 with additional glucose unit, namely 3-O-[beta-d glucopyranosyl-(1 -> 4)-beta-d-glucuronide] oleanolic acid 28-O-beta-d glucopyranosyl ester.

AB - The electron absorption and emission spectra were measured for the pyramidal LnPc(OAc) complexes in the solid state and co-doped in silica glass, where Ln=Er, Eu and Ho. The theoretical electron spectra were determined from the quantum chemical DFT calculation using four approximations CAM-B3LYP/LANL2DZ, CAM B3LYP/CC-PVDZ, B3LYP/LANL2DZ and B3LYP/CC-PVDZ. It was shown that the best agreement between the calculated and experimental structural parameters and spectroscopic data was reached for the CAM-B3LYP/LANL2DZ model. The emission spectra were measured using the excitations both in the ligand and lanthanide absorption ranges. The possibility of energy transfer between the phthalocyanine ligand and excited states of lanthanide ions was discussed. It was shown that the back energy transfer from metal states to phthalocyanine state is responsible for the observed emission of the studied complexes both in the polycrystalline state and silica glass.

AB - Different nano-structures of noble metals have been the conventional substrates for carrying out Surface Enhanced Raman Spectroscopy (SERS). In this paper we examine electrodeposited copper (Cu) nano-structures on pencil graphite as novel substrate to carry out SERS measurements by considering l-cystine (Cys-Cys) (dimer of the amino acid cysteine) as the probe. The formation of monolayer of the probe molecule on the substrates was confirmed using cyclic voltammetric measurements. Mode of adsorption of Cys-Cys was observed to be different on bulk Cu (taken in the wire form) and nano-structured Cu on pencil graphite. Whereas in the former the disulphide bond of Cys-Cys remained intact, it got cleaved when Cys-Cys was adsorbed on electrodeposited copper indicating the activated nature of the nano-structure compared to bulk copper. CS stretching mode of vibration underwent blue shift in Cys-Cys adsorbed on Cu on pencil graphite vis-a-vis Cys Cys adsorbed on Cu wire. Further evidence on the cleavage of the CS bond on an activated substrate was obtained by considering a bimetallic substrate comprising of silver on copper which was electrodeposited on pencil graphite. Our studies have demonstrated that nano-copper surface is an excellent substrate for SERS giving 200 MUM as lower detection limit for Cys-Cys.

AB - Electron bombardment during deposition of an Ar matrix containing a small proportion of allene generated allene cations. Further irradiation of the matrix sample at 385 nm destroyed the allene cations and formed propyne cations in solid Ar. Both cations were identified according to previously reported IR absorption bands. Using a similar technique, we recorded the ultraviolet absorption spectrum of allene cations in solid Ar. The vibrationally resolved progression recorded in the range of 266-237 nm with intervals of about 800 cm-1 was assigned to the A2E <- X2E transition of allene cations, and the broad continuum absorption recorded in the region of 229-214 nm was assigned to their B2A1 <- X2E transition. These assignments were made based on the observed photolytic behavior of the progressions and the vertical excitation energies and oscillator strengths calculated using time-dependent density functional theory. PMID- 29454252 TI - Human papillomavirus detection using PCR and ATR-FTIR for cervical cancer screening. AB - The human papillomavirus (HPV) genital infection is considered one of the most common sexually transmitted diseases worldwide, and has been associated with cervical cancer. The objective of this study was to investigate the efficacy of the diagnostic methods: polymerase chain reaction (PCR) and Fourier transform infrared (FTIR) equipped with an ATR (Attenuated Total Reflectance) unit (Pike Tech) spectroscopy, to diagnose HPV infection in women undergoing gynecological examination. Seventeen patients (41.46%) of the 41 patients analyzed were diagnosed with exophytic/condyloma acuminate lesions by clinical analysis, 29 patients (70.7%) (G1 group) of the 41 patients, showed positive result for HPV cell injury by oncotic colpocitology and 12 patients (29.3%) (G2 group), presented negative result for cellular lesion and absence of clinical HPV lesion. Four samples were obtained per patient, which were submitted oncotic colpocitology analysis (Papanicolau staining, two samples), PCR (one sample) and ATR-FTIR analysis (one sample). L1 gene was amplified by PCR technique with specific GP5+/GP6+ and MY09/MY11 primers. PCR results were uniformly positive for presence of HPV in all analyzed samples. Multivariate analysis of ATR-FTIR spectra suggests no significant biochemical changes between groups and no clustering formed, concurring with results of PCR. This study suggests that PCR and ATR-FTIR are highly sensitive technique for HPV detection. PMID- 29454253 TI - Charge transfer complex between 2,3-diaminopyridine with chloranilic acid. Synthesis, characterization and DFT, TD-DFT computational studies. AB - New charge transfer complex (CTC) between the electron donor 2,3-diaminopyridine (DAP) with the electron acceptor chloranilic (CLA) acid has been synthesized and characterized experimentally and theoretically using a variety of physicochemical techniques. The experimental work included the use of elemental analysis, UV-vis, IR and 1H NMR studies to characterize the complex. Electronic spectra have been carried out in different hydrogen bonded solvents, methanol (MeOH), acetonitrile (AN) and 1:1 mixture from AN-MeOH. The molecular composition of the complex was identified to be 1:1 from Jobs and molar ratio methods. The stability constant was determined using minimum-maximum absorbances method where it recorded high values confirming the high stability of the formed complex. The solid complex was prepared and characterized by elemental analysis that confirmed its formation in 1:1 stoichiometric ratio. Both IR and NMR studies asserted the existence of proton and charge transfers in the formed complex. For supporting the experimental results, DFT computations were carried out using B3LYP/6-31G(d,p) method to compute the optimized structures of the reactants and complex, their geometrical parameters, reactivity parameters, molecular electrostatic potential map and frontier molecular orbitals. The analysis of DFT results strongly confirmed the high stability of the formed complex based on existing charge transfer beside proton transfer hydrogen bonding concordant with experimental results. The origin of electronic spectra was analyzed using TD-DFT method where the observed lambdamax are strongly consisted with the computed ones. TD-DFT showed the contributed states for various electronic transitions. PMID- 29454254 TI - Exploration research on synthesis and application of a new dye containing di-2 picolyamine. AB - A newly designed fluorescence dye L based on di-2-picolyamine (DPA) moiety as a chelator was obtained under the protection of N2 at 120 degrees C, and KI as catalyst with relatively better yield. More interestingly, L not only could selectively and sensitively detect Cu2+ ions in aqueous medium but also examine the Cu2+ ions of the actual water samples. Nevertheless, L could be visual in Hela cells with excellent cell permeability, viz, monitoring exogenous Cu2+ ions as well as realizing an "on-off-on" process. PMID- 29454255 TI - Effects of adjunctive eslicarbazepine acetate on neurocognitive functioning in children with refractory focal-onset seizures. AB - PURPOSE: This was a phase-II, randomized, double-blind (DB), placebo-controlled study aimed to evaluate neurocognitive effects of eslicarbazepine acetate (ESL) as adjunctive therapy in pediatric patients with refractory focal-onset seizures (FOS). METHODS: Children (6-16years old) with FOS were randomized (2:1) to ESL or placebo. Treatment started at 10mg/kg/day, was up-titrated up to 30mg/kg/day (target dose), and maintained for 8weeks, followed by one-year open-label follow up. The primary endpoint was change from baseline to the end of maintenance period in the composite Power of Attention assessed with the Cognitive Drug Research (CDR) system. Behavioral and emotional functioning and quality of life (QOL), secondary endpoints, were assessed with Child Health Questionnaire-Parent Form 50 (CHQ-PF50), Child Behavior Checklist (CBCL), and Raven's Standard Progressive Matrices (SPM). Efficacy was evaluated through changes in standardized seizure frequency (SF), responder rate, and proportion of seizure free patients. Safety was evaluated by the incidence of treatment-emergent adverse events (TEAEs). RESULTS: One hundred and twenty-three patients were randomized. A noninferiority analysis failed to reject the null hypothesis that the change from baseline in the Power of Attention score in the ESL group was at least 121ms inferior to the placebo group for all age groups. The CDR scores showed no differences between placebo and ESL in Power of Attention (1868.0 vs 1759.5), Continuity of Attention (1.136 vs -1.786), Quality of Working Memory ( 0.023 vs -0.024), and Speed of Memory (-263.4 vs -249.6). Nonsignificant differences between placebo and ESL were seen for CHQ-PF50, CBCL scores, and Raven's SPM. Episodic Memory Index showed significant negative effect on ESL. Efficacy results favored the ESL group (SF least square [LS] means 1.98 vs 4.29). The TEAEs had a similar incidence between treatment groups (41.0% vs 47.5%). CONCLUSIONS: Overall ESL did not produce statistically significant effects on neurocognitive and behavioral functioning in patients with epilepsy aged 6 to 16years. Additionally, ESL was effective in reducing seizure frequency and was well-tolerated. PMID- 29454256 TI - Five-month-old infants have expectations for the accumulation of nonsolid substances. AB - Infants fail to represent quantities of non-cohesive substances in paradigms where they succeed with solid objects. Some investigators have interpreted these results as evidence that infants do not yet have representations for substances. More recent research, however, shows that 5-month-old infants expect objects and substances to behave and interact in different ways. In the present experiments, we test whether infants have expectations for substances when the outcomes are not simply the opposite of those for objects. In Experiment 1, we find that 5 month-old infants expect that when a cup of sand pours behind a screen, it will accumulate in just one pile rather than two. Similarly, infants expect that when two cups of sand pour in separate streams, two distinct piles will accumulate rather than one. Infants look significantly longer at outcomes with an inconsistent number of piles, providing evidence that infants have expectations for how sand accumulates. To test whether the number of cups or the number of pours guided expectations about accumulation, Experiment 2 placed these cues in conflict. This resulted in chance performance, suggesting that, for infants to build expectations about these outcomes, they need both cues (cup and pour) to converge. These findings offer insight into the nature of infants' representations for non-cohesive substances like sand. PMID- 29454257 TI - Infants' agent individuation: It's what's on the insides that counts. AB - Adults and preschool-aged children believe that internal properties are more important than external properties when determining an agent's identity over time. The current study examined the developmental origins of this understanding using a manual-search individuation task with 13-month-old infants. Subjects observed semi-transparent objects that looked and behaved like animate agents placed into box that they could reach but not see into. Across trials infants observed objects with either the same- or different-colored insides placed into the box. We found that infants used internal property differences more than external property differences to determine how many agents were involved in the event. A second experiment confirmed that this effect was specific to the domain of animate entities. These results suggest that infants are biased to see an agent's 'insides' as more important for determining its identity over time than its outside properties. PMID- 29454258 TI - The role of dissociation in revictimization across the lifespan: A 32-year prospective study. AB - Exposure to childhood abuse puts women at risk for revictimization in adult intimate relationships, but knowledge about the mechanism by which it occurs is limited. The present study investigated whether dissociation mediates the effect of exposure to physical or sexual child abuse on intimate partner violence in adulthood. We tested this using prospective data collected from birth to age 32 from 80 female participants in the Minnesota Longitudinal Study of Risk and Adaptation. We found that women who experienced sexual or physical abuse during the first 17.5 years of life (n = 37) were more likely (r = 0.30, p < .01) to experience intimate partner violence in adulthood (ages 20-32). Furthermore, we found that dissociation partially mediated this effect. Specifically, exposure to childhood abuse predicted greater dissociation in late adolescence (age 19), which in turn predicted more intimate partner violence during early to mid adulthood. The results of this study highlight the mediating role played by dissociation in the revictimization of women abused during childhood, and speak to the need to develop interventions designed to prevent intimate partner violence among abused girls or adult women with a history of abuse. PMID- 29454259 TI - The cellular mechanisms and consequences of centromere drive. AB - During female meiosis, only one of four meiotic products is retained in the egg. It was previously proposed that chromosomes might compete for inclusion in the egg via their centromere 'strength'. Recent findings have revealed the primary requirements for such 'centromere drive'. First, CDC42 signaling from the oocyte cortex renders the meiotic I spindle asymmetric. Second, 'stronger' centromeres preferentially detach from microtubules in cortical proximity, making them more likely to orient away from the cortex, and be included in the egg. Third, centromeric satellite DNA expansions result in greater recruitment of centromeric proteins. Despite these mechanistic insights, it is still unclear if centromere drive elicits rapid evolution of centromeric proteins, thereby driving cellular incompatibilities and wreaking havoc on centromere stability. PMID- 29454260 TI - Solar photo-Fenton treatment of microcystin-LR in aqueous environment: Transformation products and toxicity in different water matrices. AB - Transformation products and toxicity patterns of microcystin-LR (MC-LR), a common cyanotoxin in freshwaters, during degradation by solar photo-Fenton process were studied in the absence and presence of two major water components, namely fulvic acid and alkalinity. The transformation products m/z 795, 835, 515/1030 and 532 can be formed through attack of OH on the conjugated carbon double bonds of Adda. Transformation products with m/z 1010, 966 and 513 can be generated through the attack of OH on the methoxy group of Adda. The transformation products m/z 783, 508 and 1012 can be originated from the attack of OH on the cyclic structure of MC-LR. Transformation products (m/z 522, 1028, 1012, 1046 and 514) formed after hydroxylation of the aromatic ring with OH were also identified in this study. The toxicity study revealed that fulvic acid and alkalinity strongly influence the toxicity profiles of solar photo-Fenton treated MC-LR. Fulvic acid enhanced the detoxification whereas low level total alkalinity (1.8 mg L-1 CaCO3) inhibited the detoxification of MC-LR by solar photo-Fenton process as assessed by protein phosphatase-1 (PP-1) inhibition assay. This work provides insights on the utility of solar photo-Fenton destruction of MC-LR in water based on transformation products and toxicity data. PMID- 29454262 TI - The influence of evaluation recommendations on instrumental and conceptual uses: A preliminary analysis. AB - Evaluation recommendations are sometimes included in evaluation reports to highlight specific actions to be taken to improve a program or to make other changes to its operational context. This preliminary study sought to examine evaluation recommendations drawn from 25 evaluation reports published by Canadian federal government departments and agencies, in order to examine the evaluation issues covered and the focus of the recommendations. Our results show that in keeping with policy requirements, the evaluation recommendations focused on program relevance, effectiveness and efficiency and economy. Furthermore, a significant number of recommendations also focused on the implementation of more rigorous performance measurement strategies. The focus of the recommendations did not vary by publication date, recommendation type, and organizational sector. The findings also show that for the most part, the management responses produced as part of the broader evaluation process support the recommendations included in the report and identify specific timelines for implementation. PMID- 29454263 TI - Homeless youth: Barriers and facilitators for service referrals. AB - Young people who are homeless and experiencing mental health issues are reluctant to use relevant services for numerous reasons. Youth are also at risk of disengaging from services at times of referral to additional or alternative services. This study aimed to identify barriers and facilitators for inter service referrals for homeless youth with mental health issues who have already engaged with a service. Qualitative, semi-structured interviews were conducted with homeless youth (n = 10), homelessness support workers (n = 10), and mental health clinicians (n = 10). Barriers included: resource shortages; programs or services having inflexible entry criteria; complexity of service systems; homeless youth feeling devalued; and a lack of communication between services, for example, abrupt referrals with no follow up. Referral facilitators included: services providers offering friendly and client-centred support; supported referrals; awareness of other services; and collaboration between services. Relationships with service providers and inter-service collaboration appeared essential for successful referrals for homeless youth. These facilitating factors may be undermined by sector separation and siloing, as well as resource shortages in both the homelessness and mental health sectors. Service transitions may be conceptualised as a genuine service outcome for homeless youth, and as a basis for successful future service provision. PMID- 29454261 TI - Frequency of Somatic TP53 Mutations in Combination with Known Pathogenic Mutations in Colon Adenocarcinoma, Non-Small Cell Lung Carcinoma, and Gliomas as Identified by Next-Generation Sequencing. AB - The tumor suppressor gene TP53 is the most frequently mutated gene in human cancer. It encodes p53, a DNA-binding transcription factor that regulates multiple genes involved in DNA repair, metabolism, cell cycle arrest, apoptosis, and senescence. TP53 is associated with human cancer by mutations that lead to a loss of wild-type p53 function as well as mutations that confer alternate oncogenic functions that enable them to promote invasion, metastasis, proliferation, and cell survival. Identifying the discrete TP53 mutations in tumor cells may help direct therapies that are more effective. In this study, we identified the frequency of individual TP53 mutations in patients with colon adenocarcinoma (48%), non-small cell lung carcinoma (NSCLC) (36%), and glioma/glioblastoma (28%) at our institution using next-generation sequencing. We also identified the occurrence of somatic mutations in numerous actionable genes including BRAF, EGFR, KRAS, IDH1, and PIK3CA that occurred concurrently with these TP53 mutations. Of the 480 tumors examined that contained one or more mutations in the TP53 gene, 219 were colon adenocarcinomas, 215 were NSCLCs, and 46 were gliomas/glioblastomas. Among the patients positive for TP53 mutations diagnosed with colon adenocarcinoma, 50% also showed at least one mutation in pathogenic genes of which 14% were BRAF, 33% were KRAS, and 3% were NRAS. Forty seven percent of NSCLC patients harboring TP53 mutations also had a mutation in at least one actionable pathogenic variant with the following frequencies: BRAF: 4%, EGFR: 10%, KRAS: 28%, and PIK3CA: 4%. Fifty-two percent of patients diagnosed with glioma/glioblastoma with a positive TP53 mutation had at least one concurrent mutation in a known pathogenic gene of which 9% were CDKN2A, 41% were IDH1, and 11% were PIK3CA. PMID- 29454264 TI - Development and validation of UPLC-MS/MS assay for quantification of cladrin: Absolute bioavailability and dose proportionality study in rats. AB - Cladrin, an isoflavone is a major bioactive constituent found in stem bark of Butea monosperma with remarkable osteogenic activity. A speedy and sensitive UPLC coupled tandem mass spectrometry (UPLC-MS/MS) method was developed, validated and successfully applied to bioavailability, blood partitioning, plasma protein binding, intravenous and multiple-dose oral pharmacokinetics of cladrin in rats. Separation was done on C18 column (5.0 MUm, 4.6 * 50 mm) using mobile phase containing acetonitrile and 0.10% formic acid in the ratio of 65:35 (v/v) with 0.60 mL/min flow rate. The method was highly sensitive and has a short run time of 2.50 min with an excellent linearity (R2 > 0.99) in the range of 0.20-200 MUg/L. Absolute bioavailability was found to be 16.58, 19.04 and 6.76% at oral doses of 5, 10, and 20 mg/Kg, respectively. Cladrin was rapidly absorbed (Tmax 3.0 h) with a high apparent volume of distribution (15.03 +/- 1.79L/Kg), high clearance (2.27 +/- 0.30L/h/Kg) and high plasma protein binding. The present study is a first comprehensive in-vitro as well as the in-vivo preclinical pharmacokinetic report of cladrin giving insights about its drug-likeness and further development as a potential therapeutic agent. PMID- 29454265 TI - Supplementation of lycopene attenuates lipopolysaccharide-induced amyloidogenesis and cognitive impairments via mediating neuroinflammation and oxidative stress. AB - Neuroinflammation is documented to be the major culprit of Alzheimer's disease. Lycopene (LYC), a fat soluble carotenoid, exhibits neuroprotective function in several neurodegenerative disorders. However, the effects of LYC to countering systemic inflammation-induced amyloidogenesis and memory deficiency remain to be elucidated. In current study, 3-month-old male C57BL/6J mice were treated with 0.03% LYC (w/w, mixed into normal chow) for 5 weeks. The mice were then treated by intraperitoneal injection of LPS (0.25mg/kg) for 9 days. It was found that LYC inhibited LPS-induced memory loss by behavior tests including Y-maze test and Morris water test. Meanwhile, LYC prevented LPS-induced accumulation of Abeta, levels of amyloid precursor protein (APP), and suppressed neuronal beta-secretase BACE1 and elevated the expressions of alpha-secretase ADAM10. Furthermore, LYC down-regulated the expression of IBA-1 (a marker of microglia activation), reduced the levels of inflammatory mediators and inhibited oxidative stress in LPS-treated mice. Moreover, LYC suppressed the phosphorylation of MAPKs, NFkappaB, and activated Nrf2 signaling pathways in LPS-treated BV2 microglial cells. Therefore, our study indicated that LYC could ameliorate LPS-induced neuroinflammation, oxidative stress, amyloidogenesis and cognitive impairments possibly through mediating MAPKs, NFkappaB and Nrf2 signaling pathways, indicating that LYC might be a nutritional preventive strategy in neuroinflammation-related diseases such as AD.

AB - OBJECTIVE: To compare the diagnostic performance of estimated energy loss (EEL) with diameter stenosis (DS) to estimate significant stenosis by fractional flow reserve (FFR). MATERIALS AND METHODS: One hundred twenty-five patients were included. EEL was calculated using DS, lesion length, minimal lumen area and left ventricular volume. FFR <= 0.80 was determined significant. RESULTS: EEL improved the accuracy from 63% (95% confidence interval (CI): 55-72%) to 83% (95% CI: 75 89%, p < 0.0001). EEL increased the area under the receiver operating characteristics curve from 0.63 to 0.85 (p < 0.0001). CONCLUSIONS: EEL improved the diagnostic performance to detect functionally significant stenosis than DS. PMID- 29454267 TI - Necrotizing infection of the heart. AB - A case of necrotizing infection of the heart is presented. A 70-year-old woman presented with vague chest and abdominal pain. CT of the abdomen and pelvis was initially obtained, which demonstrated gas in the myocardium of the left ventricle. Subsequent chest CT, endoscopy, and abdominal surgical exploration did not reveal perforated viscus or diaphragm compromise. At median sternotomy, the inferior wall of the heart was found to be necrotic. Culture of the excised tissue grew E. coli. The patient expired shortly after surgical exploration. PMID- 29454268 TI - Occurrence and distribution of antibiotics in mariculture farms, estuaries and the coast of the Beibu Gulf, China: Bioconcentration and diet safety of seafood. AB - The occurrence, distribution, bioconcentration and diet safety via seafood consumption of 19 antibiotics were investigated in eight closed mariculture ponds, four estuaries, two nearshore areas and one offshore area from the Beibu Gulf. Seventeen, 16, 15 and 7 antibiotics were detected at total concentrations of 43.2 - 885 ng L-1, 22.4 - 118 ng L-1, 22.7 - 24.5 ng L-1, and 1.81-3.23 ng L-1 in the water of the above different areas, respectively. This indicates that the mariculture ponds are important sources of antibiotic pollution on the coast of the Beibu Gulf. Ten antibiotics were detected in feed samples with concentrations ranging from 0.03 to 95.4 ng g-1, demonstrating the presence of antibiotics in the feed and/or residual antibiotics in the raw material of the feed. The field bioconcentration factors (BCFs) of the antibiotics calculated in different culture organisms ranged from 0.55 to 10,774 L kg-1. The estimated daily intakes (EDIs) of sulphonamides, fluoroquinolones, macrolides and chloramphenicols via aquatic products were 19.8-105, 33.7-178, 34.9-186 and 6.9-37.1 ng d-1, respectively. According to the acceptable daily intakes (ADIs) and maximum residue limits (MRLs) proposed by different organisations, these aquatic products (shrimp, crab and oyster) reached the standard of safe consumption and could not pose a health risk to humans. However, a potential elevated risk to humans may remain because of the occurrence of multiple antibiotics in the cultured organisms, particularly for sensitive populations, such as pregnant women, the elderly and children. PMID- 29454269 TI - Biological effects of four iron-containing nanoremediation materials on the green alga Chlamydomonas sp. AB - As nanoremediation strategies for in-situ groundwater treatment extend beyond nanoiron-based applications to adsorption and oxidation, ecotoxicological evaluations of newly developed materials are required. The biological effects of four new materials with different iron (Fe) speciations ([i] FerMEG12 - pristine flake-like milled Fe(0) nanoparticles (nZVI), [ii] Carbo-Iron(r) - Fe(0) nanoclusters containing activated carbon (AC) composite, [iii] Trap-Ox(r) Fe BEA35 (Fe-zeolite) - Fe-doped zeolite, and [iv] Nano-Goethite - 'pure' FeOOH) were studied using the unicellular green alga Chlamydomonas sp. as a model test system. Algal growth rate, chlorophyll fluorescence, efficiency of photosystem II, membrane integrity and reactive oxygen species (ROS) generation were assessed following exposure to 10, 50 and 500 mg L-1 of the particles for 2 h and 24 h. The particles had a concentration-, material- and time-dependent effect on Chlamydomonas sp., with increased algal growth rate after 24 h. Conversely, significant intracellular ROS levels were detected after 2 h, with much lower levels after 24 h. All Fe-nanomaterials displayed similar Z-average sizes and zeta-potentials at 2 h and 24 h. Effects on Chlamydomonas sp. decreased in the order FerMEG12 > Carbo-Iron(r) > Fe-zeolite > Nano-Goethite. Ecotoxicological studies were challenged due to some particle properties, i.e. dark colour, effect of constituents and a tendency to agglomerate, especially at high concentrations. All particles exhibited potential to induce significant toxicity at high concentrations (500 mg L-1), though such concentrations would rapidly decrease to mg or ug L-1 in aquatic environments, levels harmless to Chlamydomonas sp. The presented findings contribute to the practical usage of particle-based nanoremediation in environmental restoration. PMID- 29454270 TI - Cadmium-induced stress response of Phanerochaete chrysosporium during the biodegradation of 2,2',4,4'-tetrabromodiphenyl ether (BDE-47). AB - Cd-induced stress response of Phanerochaete chrysosporium during the biodegradation of BDE-47 was investigated in this study, with the goal of elucidating the tolerance behavior and the detoxification mechanisms of P. chrysosporium to resist the Cd stress in the course of BDE-47 biodegradation, which has implications for expanding the application of P. chrysosporium in the bioremediation of Cd and BDE-47 combined pollution. The results suggested that single BDE-47 exposure did not induce obvious oxidative stress in P. chrysosporium, but coexistent Cd significantly triggered ROS generation, both intracellular ROS level and H2O2 content showed positive correlation with Cd concentration. The activities of SOD and CAT were enhanced by low level of Cd (<= 1 mg/L), but Cd of higher doses (>1 mg/L) depressed the expression of these two antioxidant enzymes at the later exposure period (3-5 days). The intracellular content of GSH along with GSH/GSSG ratio also exhibited a bell-shaped response with a maximum value at Cd of 1 mg/L. Furthermore, Cd-induced ROS generation resulted in the lipid peroxidation, as indicated by a noticeable increment of MDA content found after 3 days. Moreover, the study also indicated that Cd less than 1 mg/L promoted the production of extracellular protein and quickened the decrease of pH value in the medium, while excessive Cd (>1 mg/L) would lead to inhibition. These findings obtained demonstrated that P. chrysosporium had a certain degree of tolerance to Cd within a specific concentration range via regulating the antioxidant levels, inducing the synthesis of extracellular protein as well as stimulating the production of organic acids, and 1 mg/L is suggested to be the tolerance threshold of this strains under Cd stress during BDE-47 biodegradation. PMID- 29454271 TI - The complexation of rhizosphere and nonrhizosphere soil organic matter with chromium: Using elemental analysis combined with FTIR spectroscopy. AB - Complexation is a main mechanism controlling the reactions between soil organic matter (SOM) and heavy metals, which still have not been fully understood up to date. The objective of this study was to compare the SOM composition of nonrhizosphere and rhizosphere in low Cr treatment with that in high Cr treatment and to find out how metal concentrations affect the complexation with SOM. The results revealed that both the hydroxyl and the carboxyl were significantly different under different Cr treatment groups. For nonrhizosphere samples, the high Cr treatment tended to have less hydroxyl contents and more structural changes on hydroxyl (3389-3381 cm-1) than the low Cr treatment (3389-3388 cm-1), while in the rhizosphere samples the reverse happened. The gap of the different Cr treated band area in the rhizosphere samples (44 a.u of the gap) was greatly smaller than that in the nonrhizosphere samples (576 a.u of the gap). In both the rhizosphere and nonrhizosphere samples, the high Cr treatment showed greater structural changes on carboxylic acids (11, 12 a.u changes based on the control) than the low Cr treatment (4, 6 a.u). The unsaturated carboxylic acids could account for downward frequency shift and the contents in the nonrhizosphere samples were slightly greater than that in the rhizosphere samples. This study used elemental analysis combined with FTIR spectroscopy to explore the effects of metal concentrations on the complexation of Cr with SOM and the composition of SOM. These findings give a way to understanding part of the complexation mechanisms between the metal and SOM. PMID- 29454272 TI - Dealing with the nucleus during cell migration. AB - The position of the nucleus within cells is a key event during cell migration. The movement and positioning of the nucleus strongly impacts cell migration. Notably, the last two years largely contributed to emphasise the dynamicity of the nucleus-cytoskeleton interactions that occur during cell migration. Nuclei are under continuous tension from opposing intracellular forces and its tether to the cytoskeleton can be regulated at different levels. Interestingly, it was showed how nuclear positioning is highly related to cell function. In most migrating cells, including cancer cells, the nucleus can be the rate limiting step of cell migration and is placed away from the leading edge. By contrast, leukocytes position their nucleus close to the lamellipodia at the leading edge, and the nucleus contributes to drilling through the endothelium. Differences in cell migration in 2D versus 3D environments are also evident. The mechanisms and forces at play during nuclear positioning and translocation are clearly affected by the nature of the substrate. As such nuclear positioning during cell migration can vary between cell types and environments. In this review we aim to give an overview of the latest discoveries in the field revealing how nuclear positioning is tightly regulated, not only by intrinsic nuclear properties, such as deformability, nuclear envelope content or nucleus-cytoskeleton connectivity, but also by the microenvironment.

AB - Mechanical signals from the extracellular space are paramount to coordinate tissue morphogenesis and homeostasis. Although there is a wide variety of cellular mechanisms involved in transducing extracellular forces, recent literature emphasizes the central role of two main adhesion complexes in epithelial mechanosensitive processes: focal adhesions and adherens junctions. These biomechanical sensors can decode physical signals such as matrix stiffness or intercellular tension into a wide range of coordinated cellular responses, which can impact cell differentiation, migration, and proliferation. Communication between cells and their microenvironment plays a pivotal role both in physiological and pathological conditions. Here we summarize the most recent findings on the biology of these mechanotransduction pathways in epithelial cells, highlighting the extensive amount of biological processes coordinated by cell-matrix and cell-cell adhesion complexes.

AB - A multifaceted coating for hard tissue implants, with favorable osteogenesis, angiogenesis, and osteoimmunomodulation abilities, would be of great value since it could improve osseointegration and alleviate prosthesis loosening. However, to date there are few coatings that fully satisfy these criteria. Herein we describe a microporous TiO2 coating decorated with hydroxyapatite (HA) nanoparticles that is generated by micro-arc oxidation of pure titanium (Ti) and followed annealing. By altering the annealing temperature, it is possible to simultaneously tune the coating's physical (morphology and wettability) and chemical (composites and crystallinity) properties. A coating produced with micro-arc oxidization (MAO) with an annealing temperature of 650 degrees C (MAO-650) exhibits numerous favorable physicochemical properties, such as hybrid micro-nano morphology, superhydrophilicity, and highly crystalline HA nanoparticles. In vitro experiments reveal that the MAO-650 coating not only supports proliferation and differentiation of both osteoblasts and endothelial cells, but also inhibits the inflammatory response of macrophages and enables a favorable osteoimmunomodulation to facilitate osteo/angio-genesis. In vivo evaluation mirrors these results, and shows that the MAO-650 coating results in ameliorative osseointegration when compared with the pristine MAO coating. These data highlight the profound effect of surface physicochemical properties on the regulation of osteo/angio-genesis and osteoimmunomodulation in the enhancement of osseointegration.

AB - In this retrospective study, a series of 10 elective patients treated with transfer of the tibialis posterior (TP) tendon for pes cavus and drop foot are described. Since TP transfer completely subtracts the role of this tendon, this cohort of patients provides an opportunity to examine the consequences of tibialis posterior (TP) deficiency. After a mean follow up period of 44.7 months, only one patient showed evidence of strain in the spring ligament but none of the patients in this series developed clinical or radiological evidence of planovalgus deformity. The authors conclude that planovalgus deformity is not an inevitable sequelae of TP Tendon transfer and that established theory underestimates the role of static soft tissue restraints such as spring ligament in hindfoot stability. PMID- 29454276 TI - Use of mixed wastewaters from piggery and winery for nutrient removal and lipid production by Chlorella sp. MM3. AB - The larger-scale generation of piggery and winery wastewaters and consequent eutrophication are quite alarming, necessitating the use of a cost-effective treatment. This study attempted to remediate wastewaters from piggery and winery mixed in the ratios of 20:80, 50:50, 80:20, 100:0 and 0:100, in terms of nutrient removal and subsequent lipid accumulation by soil microalga, Chlorella sp. MM3. The per cent removal of total nitrogen and phosphates by the alga from mixed wastewaters within 10-days ranged between 51 and 89 and 26-49, respectively. As determined by FTIR spectroscopy, the lipid accumulation in the microalgal cells grown in wastewater mixtures ranged between 29 and 51%. Our results suggest that Chlorella sp. MM3 could be a potential candidate for bioremediation of wastewaters derived from piggery farm and winery industry, and that mixing of these wastewaters in 20:80 ratio would be an efficient approach for phycoremediation of mineral-rich effluents and subsequent yield of fairly good amounts of biofuel. PMID- 29454277 TI - Nitrogen removal enhancement using lactic acid fermentation products from food waste as external carbon sources: Performance and microbial communities. AB - In this study, nitrogen removal using the lactic acid fermentation products from food waste and other external chemical carbon sources (sodium acetate, sodium lactate and starch) was investigated. Similar to sodium acetate and lactate, the lactic acid-enriched fermentation liquid from food waste (FLFW) exhibited a high denitrification rate (5.5 mg NOx-N/(g-VSS h)) and potential (0.16 g NO3--N/g COD), and could achieve high NH4+-N and total nitrogen (TN) removal efficiencies during long-term operation. Using FLFW as supplementary carbon sources reduced the extracellular polymeric substances (EPS) content, improved the settleability and achieved a satisfactory biomass yield of activated sludge. Additionally, the increased microbial metabolic activity and bacterial community diversity and the accumulation of unique bacteria in the activated sludge cultured with FLFW further promoted the organics utilization rate and nitrogen removal efficiency, indicating that the FLFW prepared from solid waste was an ideal carbon source for wastewater treatment.

AB - Pyrolysis under protective atmosphere was regarded as an indispensable process for the preparation of biomass-based adsorbents to achieve higher surface areas. In this paper, magnetic carbon composites (MCC) that fabricated under air atmosphere showed an adsorption capacity of 167.22 mg/g in 200 ppm Hg(II), which was significantly higher than magnetic biochar (MBC, 31.80 mg/g) that fabricated under traditional nitrogen protection, and this remarkable performance of MCC was consistent in a wide range of pHs. Based on BET, XRD, FTIR, SEM and Boehm titration, MCC was demonstrated with limited surface area (43.29 m2/g) but large amount of surface functional groups comparing with MBC. Additionally, gamma-Fe2O3 with a high degree of crystallization was generated in MCC, which led to a better magnetic property and recyclability. Moreover, characterizations, Langmuir isotherm and pseudo-second-order kinetics demonstrated the chemisorption was dominant for MCC in mercury capture, and surface complexation co-precipitate of Hg4Fe8O16C56H40 were also formed. PMID- 29454279 TI - Bonding of composite cements to zirconia: A systematic review and meta-analysis of in vitro studies. AB - OBJECTIVES: The aim of this study was to systematically review the literature and statistically analyze bond strength data to identify the influence that composite cements, type of test methodology, chemical and mechanical pre-treatments have on the bond strength of composite cements to zirconia in three different artificial aging conditions. METHODS: The literature was electronically searched in MEDLINE, PUBMED, EMBASE, and SCOPUS to select relevant articles that evaluated the bond strength between zirconia and composite cements. A manual search was performed by scanning the reference lists of included studies. All articles were published online before December 2016 and in English. From electronic database and manual searches, 444 studies were identified; 161 articles with 1632 test results met the inclusion criteria. Test results were assigned into 3 aging conditions: non aged, intermediate-aged and aged groups. Generalized estimating equations (GEE) were used to explore actual mean bond strengths. As the bond strength is a non negative value, lognormal distribution was used. RESULTS: In non-aged condition, data showed statistically significant interactions between cement type and type of test. There was no statistically significant interaction between mechanical and chemical pre-treatments. In intermediate-aged and aged conditions, data showed no statistically significant interactions between mechanical and chemical pre-treatments and between cement type and type of test. CONCLUSIONS: This meta analysis appeared to indicate that mechanical pre-treatments, and in particular ceramic coating, combined with methacryloyloxydecyl dihydrogen phosphate (MDP) containing primers yielded the highest long-term bond strength (aged-condition). However, data are limited and caution should be exercised before applying these results to clinical situations. PMID- 29454280 TI - 8-Chrysoeriol, as a potential BCL-2 inhibitor triggers apoptosis of SW1990 pancreatic cancer cells. AB - 8-Chrysoeriol, a bioactive flavanoid, was firstly identified to bind directly to BCL-2 as BH3 mimetics by structure-based virtual ligand screening. And 3D docking model revealed the molecular basis of 8-Chrysoeriol targeting to BCL-2. The interaction between 8-Chrysoeriol and BCL-2 was further confirmed using Microscale Thermophoresis (MST) technique. Meanwhile, high expression level of antiapoptotic protein BCL-2 was detected in SW1990 pancreatic cancer cells and 8 Chrysoeriol showed obvious proapoptosis effect against SW1990 in vitro. Collectively, the results showed that 8-Chrysoeriol as a natural dietary product potentially targeting to BCL-2 could serve as a lead compound for SW1990 pancreatic cancer therapy. PMID- 29454281 TI - Probing the beta-pocket of the active site of human liver glycogen phosphorylase with 3-(C-beta-d-glucopyranosyl)-5-(4-substituted-phenyl)-1, 2, 4-triazole inhibitors. AB - Human liver glycogen phosphorylase (hlGP), a key enzyme in glycogen metabolism, is a valid pharmaceutical target for the development of new anti-hyperglycaemic agents for type 2 diabetes. Inhibitor discovery studies have focused on the active site and in particular on glucopyranose based compounds with a beta-1 substituent long enough to exploit interactions with a cavity adjacent to the active site, termed the beta-pocket. Recently, C-beta-d-glucopyranosyl imidazoles and 1, 2, 4-triazoles proved to be the best known glucose derived inhibitors of hlGP. Here we probe the beta-pocket by studying the inhibitory effect of six different groups at the para position of 3-(beta-d-glucopyranosyl phenyl)-5 phenyl-, 1, 2, 4-triazoles in hlGP by kinetics and X-ray crystallography. The most bioactive compound was the one with an amine substituent to show a Ki value of 0.43 MUM. Structural studies have revealed the physicochemical diversity of the beta-pocket providing information for future rational inhibitor design studies. PMID- 29454282 TI - Contaminants of emerging concern presence and adverse effects in fish: A case study in the Laurentian Great Lakes. AB - The Laurentian Great Lakes are a valuable natural resource that is affected by contaminants of emerging concern (CECs), including sex steroid hormones, personal care products, pharmaceuticals, industrial chemicals, and new generation pesticides. However, little is known about the fate and biological effects of CECs in tributaries to the Great Lakes. In the current study, 16 sites on three rivers in the Great Lakes basin (Fox, Cuyahoga, and Raquette Rivers) were assessed for CEC presence using polar organic chemical integrative samplers (POCIS) and grab water samplers. Biological activity was assessed through a combination of in vitro bioassays (focused on estrogenic activity) and in vivo assays with larval fathead minnows. In addition, resident sunfish, largemouth bass, and white suckers were assessed for changes in biological endpoints associated with CEC exposure. CECs were present in all water samples and POCIS extracts. A total of 111 and 97 chemicals were detected in at least one water sample and POCIS extract, respectively. Known estrogenic chemicals were detected in water samples at all 16 sites and in POCIS extracts at 13 sites. Most sites elicited estrogenic activity in bioassays. Ranking sites and rivers based on water chemistry, POCIS chemistry, or total in vitro estrogenicity produced comparable patterns with the Cuyahoga River ranking as most and the Raquette River as least affected by CECs. Changes in biological responses grouped according to physiological processes, and differed between species but not sex. The Fox and Cuyahoga Rivers often had significantly different patterns in biological response Our study supports the need for multiple lines of evidence and provides a framework to assess CEC presence and effects in fish in the Laurentian Great Lakes basin. PMID- 29454283 TI - Investigating antibiotics, antibiotic resistance genes, and microbial contaminants in groundwater in relation to the proximity of urban areas. AB - Groundwater is an essential public and drinking water supply and its protection is a goal for global policies. Here, we investigated the presence and prevalence of antibiotic residues, antibiotic resistance genes (ARGs), mobile genetic elements (MGEs), and microbial contamination in groundwater environments at various distances from urban areas. Antibiotic concentrations ranged from below detection limit to 917 ng/L, being trimethoprim, macrolide, and sulfonamide the most abundant antibiotic classes. A total of eleven ARGs (aminoglycoside, beta lactam, chloramphenicol, Macrolide-Lincosamide-Streptogramin B - MLSB, sulfonamide, and tetracycline), one antiseptic resistance gene, and two MGEs were detected by qPCR with relative abundances ranging from 6.61 * 10-7 to 2.30 * 10-1 copies/16S rRNA gene copies. ARGs and MGEs were widespread in the investigated groundwater environments, with increased abundances not only in urban, but also in remote areas. Distinct bacterial community profiles were observed, with a higher prevalence of Betaproteobacteria and Bacteroidetes in the less-impacted areas, and that of Firmicutes in the contaminated groundwater. The combined characteristics of increased species diversity, distinct phylogenetic composition, and the possible presence of fecal and/or pathogenic bacteria could indicate different types of contamination. Significant correlations between ARGs, MGEs and specific taxa within the groundwater bacterial community were identified, revealing the potential hosts of resistance types. Although no universal marker gene could be determined, a co-selection of int1, qacEDelta1 and sulI genes, a proxy group for anthropogenic pollution, with the tetC, tetO, tetW resistance genes was identified. As the tet group was observed to follow the pattern of environmental contamination for the groundwater samples investigated in this study, our results strongly support the proposal of this group of genes as an environmental tracer of human impact. Overall, the present study investigated several emerging contaminants in groundwater habitats that may be included in monitoring programs to enable further regulatory and protection measures. PMID- 29454284 TI - The provision of specialist psychosocial support for people with visible differences: A European survey. AB - A substantial body of research has demonstrated the challenges commonly facing people with visible differences (disfigurements) and explored the potential benefits offered by specialist psychosocial support and intervention for those who are negatively affected. However, little is known about the availability of such support in Europe for people whose appearance is in any way different to 'the norm'. This survey of 116 psychosocial specialists from 15 European countries, working with a range of patient groups, has shown a tendency for specialists to prioritise Cognitive-behavioural-based approaches, amongst a wide range of other approaches and interventional techniques. It indicates variations in the availability of support, and a perceived need for improved access to interventions, additional training, and greater awareness of the psychosocial issues associated with visible differences. PMID- 29454285 TI - POU5F1B promotes hepatocellular carcinoma proliferation by activating AKT. AB - Hepatocellular carcinoma (HCC) is one of the most common tumors, so far, there still aren't good therapeutic methods. Looking for new targets makes a top priority. In this study, we found a OCT4 pseudogene, POU5F1B was significantly upregulated in HCC cells and tissues, patients with high POU5F1B had shorter survival time compared to patients with low POU5F1B expression. POU5F1B overexpression promoted HCC proliferation, while its knockdown inhibited HCC proliferation determined by MTT assay, soft agar growth assay, BrdU incorporation assay, and cell cycle assay. Mechanism analysis suggested POU5F1B could activate AKT, AKT inhibition in HCC cells with POU5F1B overexpression significantly inhibited cell proliferation compared to cells only with POU5F1B overexpression, suggesting POU5F1B promoted HCC proliferation by activating AKT. Finally, we analyzed the relationship between POU5F1B expression and AKT activity in HCC tissues, and found POU5F1B expression was positive correlated with activated AKT. Taken together, our findings suggested POU5F1B promoted HCC proliferation by activating AKT, and provided a new target for HCC therapy. PMID- 29454286 TI - The vasodilatory effect of allopurinol mediates its antihypertensive effect: Effects on calcium movement and cardiac hemodynamics. AB - Despite the reported reduction in blood pressure in hypertensive patients treated with allopurinol, the mechanism of the allopurinol hypotensive effect is still unclear. In the current study, the hypotensive effect of allopurinol has been fully investigated in hypertensive rats. Hypertension was induced in rats by angiotensin II (120 ng/min/kg) infusion for two weeks. Rats were then subjected to real-time recording of blood pressure, left ventricular pressure and volume and surface ECG. After 10 min of basal recording, allopurinol was slowly injected into the femoral vein with a dose of 10 MUmole/kg. Then, invasive blood pressure, cardiac hemodynamics and ECG were continuously recorded for an additional 20 min. In addition, the vasodilation effect of allopurinol was studied using the isolated artery technique. Allopurinol injection reduced systolic, diastolic and pulse blood pressure. Allopurinol suppressed both cardiac systolic and diastolic hemodynamics as is apparent from the reduction in the rate of rise and the rate of fall in left ventricular pressure. Allopurinol reduced the general cardiac output quickly. Allopurinol addition to the organ bath (10-1000 MUM) produced significant vasodilation of PE pre-constricted aortae that was not affected by endothelium denudation, L-NAME or indomethacin. However, allopurinol ameliorated the calcium induced contraction of aorta pre-constricted with KCl in calcium-free media. Erk or ROCK inhibition did not attenuated allopurinol produced vasodilation. In conclusion, allopurinol has an antihypertensive effect that is mediated, probably, by reducing cardiac output and decreasing vascular resistance. The vasodilator effect of allopurinol is most likely mediated by calcium blocking activities. PMID- 29454287 TI - The sedative activity of flavonoids from Passiflora quadrangularis is mediated through the GABAergic pathway. AB - The aim of this study was to investigate the sedative activity of the aqueous leaf extract of Passiflora quadrangularis, a species that is widely cultivated and consumed in South America, and to identify its main constituents and elucidate the involvement of the GABAergic pathway in its mechanism of action. The bioguided fractionation of the crude extract showed a positive relationship between the sedative activity of the extract and its flavonoids. The methods employed to identify and isolate its main flavonoids resulted in the identification of vitexin-2''-O-xyloside, vitexin-2''-O-glucoside, orientin-2''-O xyloside and orientin-2''-O-glucoside. Vitexin-2"-O-xyloside, the major flavonoid of the extract, showed sedative activity after oral administration in mice. PMID- 29454288 TI - Apocynum venetum leaf extract reverses depressive-like behaviors in chronically stressed rats by inhibiting oxidative stress and apoptosis. AB - BACKGROUND: Major depressive disorder (MDD) is a common but serious psychiatric disorder, but current treatments are inadequate for approximately half of the patients with MDD. Thus, better methods of treatment are urgently needed. This study aimed to investigate the antidepressant-like effects and potential mechanism of Apocynum venetum leaf extract (AVLE) in chronic unpredictable mild stress (CUMS) rat model of depression. MATERIALS AND METHODS: The CUMS rat model of depression was used to investigate the antidepressant-like activity and relevant mechanism of AVLE (30, 60, and 125 mg/kg, i.g.). Behavioral tests, including sucrose preference test (SPT), open field test (OFT), and forced swimming test (FST) were conducted to assess anhedonic, despairing, and spontaneous behaviors, respectively. The activity of the hypothalamic-pituitary adrenal (HPA) axis was evaluated by measuring the serum adrenocorticotrophic hormone (ACTH) and corticosterone (CORT) concentrations. The underlying mechanism was further explored by assessing oxidative stress parameters, cell apoptosis, and brain-derived neurotrophic factor (BDNF) expression in the rat hippocampus exposed to CUMS. RESULTS: The AVLE (36, 60, 125 mg/kg) treatment exerted antidepressant-like effects in CUMS-exposed rats similar to fluoxetine (10 mg/kg). The AVLE treatment reduced the serum CORT and ACTH levels in CUMS rats. It also increased the activities and gene expression of antioxidant enzymes (SOD, CAT, and GPx) and decreased the ROS generation levels and the lipid peroxidation marker MDA in the rat hippocampus subjected to CUMS. Additionally, it suppressed the apoptosis of hippocampus cells by modulating Bcl-2/Bax pathways and improved the hippocampal BDNF expressions of CUMS rats. CONCLUSION: Our findings suggested that AVLE exerted antidepressant-like effects in CUMS rats, which was possibly mediated by the prevention of oxidative stress, the inhibition of hippocampal neuronal apoptosis, and the upregulation of the hippocampal BDNF level. PMID- 29454289 TI - Walking speed measurement with an Ambient Measurement System (AMS) in patients with multiple sclerosis and walking impairment. AB - BACKGROUND: Walking speed is an important measure of gait impairment in multiple sclerosis (MS). The clinical assessment of walking speed requires dedicated time, space, and personnel, and may not accurately gauge real-world performance. The term "Ambient Measurement System" (AMS) refers to a new class of device that passively measures walking speed at home, without the need for dedicated space or specialized setup. This study compared an AMS, Echo5D, versus in-clinic standard measures of walking speed on a straight path. METHODS: Twenty participants with MS and walking impairment were recruited from the Cleveland Clinic Mellen Center for MS. Each participant traversed an electronic GAITRite CIRFace (GC) sensor mat four times (two at comfortable pace, two at fast pace). Each participant then performed the Timed 25-Foot Walk (T25FW) twice, measured by a manual stopwatch (SW). All traversals were simultaneously measured by an array of Echo5D devices. Echo5D speeds were correlated with the Patient-Determined Disease Steps and the MS Walking Scale-12 patient-reported outcomes. RESULTS: Pearson correlations between Echo5D and clinical tests ranged from 0.89 to 0.98 (p < 0.0001). No statistically significant bias was found between Echo5D and GC. A small statistically significant bias was found between Echo5D and SW, with Echo5D reporting approximately 5% faster walking speeds in aggregate. CONCLUSIONS: Among MS patients with walking impairments, the Echo5D AMS acquired walking speeds which were closely correlated with the standard measures of GC and SW. The strong agreement supports the use of Echo5D to assess in-home, real-world walking performance in MS. PMID- 29454290 TI - Ligand-based computer aided drug design reveals new tropomycin receptor kinase a (TrkA) inhibitors. AB - Targeting tropomycin kinase A (TrkA) by small molecule inhibitors is considered as a promising strategy for treating several human cancers. To achieve this goal, a ligand based QSAR model was applied using the Discovery studio 4.5 (DS 4.5). Hence, a total list of 161 TrkA inhibitors was investigated. The TrkA inhibitors were extensively explored to detect their optimal physicochemical properties and pharmacophoric binding modes, which were converted into numeric descriptors and allowed to compete within the context of the Genetic Function Algorithm (GFA) approximations to find the subset of terms that correlates best with the activity. The resulted successful QSAR equation had statistical criteria of (r2129=0.67, r2LOO=0.61 r2PRESS against 32 external test inhibitors=0.50). Afterwards, the most successful pharmacophore: HypoB-T5-3, was used to screen compounds within the National Cancer institute (NCI) database. Only 41 compounds were retrieved and 21 of them exhibited anti-TrkA activity. The most potent hit had an IC50 value of 2.4MUM. Later, upon docking the active hits into the TrkA binding pocket, important interactions were revealed including hydrogen bonding with the amino acids Asp668 and Lys544 in addition to the cation-pi interactions with the sidechain of Arg559. PMID- 29454291 TI - De novo transcriptome of the pallial gland of the date mussel (Lithophaga lithophaga). AB - Lithophaga lithophaga is a rock-boring bivalve with an ability to dissolve carbonate substrata with its siphonal and pallial gland secretions. However, the molecular mechanism that enables this species to bore into calcareous rocks is not yet known. In order to identify genes potentially involved in chemical boring we performed transcriptome sequencing of pallial-gland tissue samples of L. lithophaga. Transcriptome sequencing using an Ion Torrent platform generated 60.563 million clean reads with an average read length of 96 bp. De novo assembly of clean reads produced 62,490 contigs with a mean length of 408 bp. Since the boring mechanism is attributed to calcium-binding proteins, the search focused on transcripts capable of binding this element. In all, 178 genes with calcium binding ability were found to be expressed in the pallial gland of L. lithophaga. Annexins, calreticulin, phospholipase A2 and V-type proton-ATPases were considered as possible candidate chemical-boring genes due to their known function and involvement in various other biological processes: e.g. ion transport, cellular catabolic process, protein folding. Transcriptome analysis of L. lithophaga revealed a set of candidate genes putatively associated with chemical boring. The selected set of genes will be studied further to verify their expression patterns and their possible involvement in the rate of chemical boring in L. lithophaga. PMID- 29454292 TI - The nursification of a bioscience unit and its impact on student satisfaction and learning in an undergraduate nursing degree. AB - Undergraduate nursing students traditionally find bioscience difficult, which can be compounded by an inability to relate bioscience theory to nursing practice. Subsequently, many registered nurses feel they lack knowledge in this area. Several studies have identified this problem and focused on the importance of linking bioscience theory in undergraduate nursing curricula to clinical practice. The aim of this study was to assess whether nursification (the active association of a subject with nursing theory and practice) of the bioscience content of a first year, first semester unit impacts on the students' learning experience. The study compared two student groups' perceptions of their learning experience; one group enrolled before the bioscience unit was linked to nursing practice (pre-nursification) and the other group enrolled after the content was linked to nursing practice (post-nursification). Retrospective, quantitative analysis of the mean scores of the student feedback surveys found no significant difference between the pre and post-nursification responses with respect to the students' overall satisfaction of the unit or their ability to achieve their learning objectives, however the students in the post-nursification group reported significantly higher mean scores with respect to their motivation and inspiration to learn, and to learn effectively. The findings in this study suggest that integration of nursing practice within a bioscience unit can improve the learning experience of undergraduate nursing students. PMID- 29454293 TI - Health professions faculty beliefs, confidence, use, and perceptions of organizational culture and readiness for EBP: A cross-sectional, descriptive survey. AB - BACKGROUND: Evidence-based practice (EBP) is an essential skill and ethical obligation for all practicing health professions clinicians because of its strong association with improved health outcomes. Emerging evidence suggests that faculty who prepare these clinicians lack proficiency to teach EBP. OBJECTIVES: The purpose of this study was to describe; 1) health profession faculty beliefs about and confidence in their ability to teach and implement EBP, 2) use of EBP for education, 3) organizational culture and readiness for EBP; and to determine whether relationships exist among these variables. DESIGN: This study used a cross-sectional, descriptive survey design. SETTING AND PARTICIPANTS: College of Nursing (CON) and College of Health Professions (CHP) faculty from a university located in the Northeast, United States. Faculty were defined as anyone teaching a course for the CON or CHP during the fall of 2016. METHODS: Faculty were invited to complete an electronic survey measuring EBP beliefs, EBP use, and EBP organizational culture and readiness. The survey was comprised of three tools developed specifically for health professions educators in 2010 by Fineout Overholt & Melnyk. RESULTS: Sixty-nine faculty returned usable surveys (25.5% response rate). Mean EBP beliefs score was 89.49 (SD = 10.94) indicating respondents had a firm belief in and confidence in their ability to implement and teach EBP. Mean EBP use was 32.02 (SD = 20.59) indicating that respondents taught and implemented EBP between 1 and 3 times in the last 8-weeks. Mean EBP culture and readiness score was 90.20 (SD = 15.23) indicating essential movement toward a sustainable culture of college-wide integration of EBP. Mean scores for beliefs/confidence were higher for full-time clinical faculty compared to other groups [F(2, 55) = 0.075, p = 0.928; etap2 = 0.003)]. Adjunct faculty reported higher EBP behaviors expected by health profession educators in the last 8-weeks compared to other groups [F(2, 55) = 0.251, p = 0.779; etap2. =0.009)]. Adjunct faculty had the highest mean scores on OCRSIEP-E followed by full-time clinical faculty. These group differences in OCRSIEP-E were statistically significant [F(2, 49) = 7.92, p = 0.001; etap2 = 0.244)]. OCRSIEP-E was significantly different between full-time tenure/tenure track faculty (M = 78.0, SD = 12.58) and full-time clinical faculty (M = 91.37, SD = 14.79, p = 0.027) and between full-time tenure/tenure track faculty and adjunct faculty (M = 97.19, SD = 12.39, p = 0.001). CONCLUSIONS: Faculty adoption of EBP as a foundational pillar of teaching is essential. Research is needed to define the scope of the problem internationally. Organizations need to set standards for faculty teaching in the health professions to be EBP proficient. Programs preparing faculty to teach in nursing and other health professions must include educator EBP competencies. PMID- 29454294 TI - Parents' and early adolescents' self-efficacy about anger regulation and early adolescents' internalizing and externalizing problems: A longitudinal study in three countries. AB - The present study examines whether early adolescents' self-efficacy beliefs about anger regulation mediate the relation between parents' self-efficacy beliefs about anger regulation and early adolescents' internalizing and externalizing problems. Participants were 534 early adolescents (T1: M age = 10.89, SD = .70; 50% female), their mothers (n = 534), and their fathers (n = 431). Families were drawn from Colombia, Italy, and the USA. Follow-up data were obtained two (T2) and three (T3) years later. At T1 and T3, parents' self-efficacy beliefs were self-reported and internalizing and externalizing problems were assessed via mothers', fathers', and early adolescents' reports. At T2, early adolescents' self-efficacy beliefs were self-reported Within the overall sample, mothers with higher self-efficacy beliefs about anger regulation had children with similar beliefs. Early adolescents' low self-efficacy beliefs were associated with higher internalizing and externalizing problems. PMID- 29454295 TI - Synthetic and genetically encoded fluorescent neural activity indicators. AB - The ultimate goal of neuroscience is to relate the complex activity of cells and cell-networks to behavior and cognition. This requires tools and techniques to visualize neuronal activity. Fluorescence microscopy is an ideal tool to measure activity of cells in the brain due to the high sensitivity of the technique and the growing portfolio of optical hardware and fluorescent sensors. Here, we give a chemist's perspective on the recent progress of fluorescent activity indicators that enable the measurement of cellular events in the living brain. We discuss advances in both chemical and genetically encoded sensors and look forward to hybrid indicators, which incorporate synthetic organic dyes into genetically encoded protein constructs. PMID- 29454296 TI - Effect of multiple low-dose PGF2alpha injections on the mature corpus luteum in non-pregnant bitches. AB - This study investigated molecular regulation in the canine corpus luteums/corpora lutea (CL) following multiple low-dose prostaglandin F2 alpha (PGF2alpha) injections in non-pregnant bitches around 30-35 days after ovulation. The CL were obtained by ovariohysterectomy 1 h after the last PGF2alpha injection. The subjects were divided into the following groups: control (no PGF2alpha injection, n = 4), one PGF2alpha injection (injection at 0 h, 1PGF, n = 4), two PGF2alpha injection (injection at 0 and 8 h, 2PGF, n = 4), and three PGF2alpha injection (injection at 0, 8 and 24 h, 3PGF, n = 4). In the 1PGF group, the steady-state mRNA levels of an immediate early gene (NR4A1) and immune system-related genes (MCP-1 and IL-8) increased. NR4A1 was localized in luteal and endothelial cells. In contrast, MCP-1 was localized in the luteal tissue between the luteal and endothelial cells. LHCGR, CYP11A1, and StAR mRNA expression decreased after the second PGF2alpha injection. FASLG increased only after the third PGF2alpha injection. The mRNA levels of PTGFR, PGT, and PTGS2 decreased as the number of PGF2alpha injections increased. Immunohistochemistry showed a decrease in StAR protein density as the number of PGF2alpha injections increased. BAX and CASP3 mRNA expression levels were similar among the groups. Serum progesterone (P4) levels decreased dramatically after the PGF2alpha injections but were still higher than the basal level at the end of the study. In conclusion, repeated low dose PGF2alpha injections could induce luteolytic mechanisms in the CL of non pregnant bitches. Furthermore, it can be concluded that, in non-pregnant bitches, some aspects of the molecular regulation of luteolysis in the CL are similar to some aspects of such regulation in other domestic animals. PMID- 29454297 TI - Intracytoplasmic sperm injection (ICSI) of in vitro matured oocytes with stored epididymal spermatozoa in camel (Camelus dromedarius): Effect of exogenous activation on in vitro embryo development. AB - Experiments were conducted to investigate the development of in vitro matured camel oocytes after their intra-cytoplasmic sperm injection (ICSI) with epididymal sperm collected from slaughtered male camels. Ovaries and testes were collected from a local slaughterhouse in normal saline solution (NSS) at 37 degrees C and on ice (0-1 degrees C), respectively. Cumulus-oocyte complexes (COCs) aspirated from the follicles were randomly distributed to 4-well culture plates (20-25 COCs/well) containing 500 MUL of maturation medium and cultured at 38.5 degrees C in an atmosphere of 5% CO2 in air for about 30 h. Spermatozoa were collected from the cauda epididymites in syringes containing 2-3 mL of tris tes egg yolk extender. They were cooled down slowly and stored at refrigeration (4 degrees C) temperature. On the day of use, spermatozoa were prepared by the swim up technique before use in ICSI. The injected oocytes were either activated by ionomycin and roscovitine or put into the culture without any chemical activation. In Experiment 1, presumptive zygotes were fixed and stained with Hoechst 33342 for evaluation of fertilization after 18 h of culture, while, in Experiment 2, they were cultured in 500 MUL of the culture medium at 38.5 degrees C in an atmosphere of 5% CO2, 5% O2 and 90% N2 in air for 7 days to evaluate their development. The proportion of oocytes activated when ICSI was followed by chemical activation was significantly higher (P < 0.05) when compared with non-activated ones. In experiment 2, a higher number of oocytes cleaved (59 vs. 35%) and developed to blastocysts (20 vs. 7%) in the group with post-ICSI activation when compared with the group without chemical activation, respectively. In conclusion, to the best of our knowledge, this is the first report where embryos were produced by ICSI in camels. Chemical activation of oocytes by ionomycin and roscovitine, post -ICSI, enhanced their cleavage and development to blastocyst stage. PMID- 29454298 TI - Is the biparietal diameter of fetuses in late gestation too variable to predict readiness for cesarean section in dogs? AB - Correct assessment of readiness for cesarean section is essential for timing elective cesarean section during late pregnancy in the bitch. In humans, biparietal diameter is sufficiently precise and accurate and used in a clinical setting daily. The objectives of this study were to determine whether fetal biparietal diameter in late gestation in the dog could be used to predict readiness for cesarean section by having reached a minimum cut-off value and to correlate the biparietal diameter to birth weight. The biparietal diameter of 208 puppies in 34 litters from 31 English bulldog bitches and 660 puppies in 78 litters from 70 Boerboel bitches were measured immediately after delivery by cesarean section, performed at full term, using digital calipers. At the same time the birth weight of the same 208 English bulldog puppies and 494 of the same Boerboel puppies in 59 litters from 54 bitches was measured by means of an electronic scale. With a cesarean section, all the puppies in a litter are delivered simultaneously and readiness for cesarean section must be determined for a litter. The minimum, median and maximum biparietal diameter varied from 21.1 to 47.8, 32.9 to 50.0 and 34.2-58.2 mm, respectively, among English bulldog litters and from 18.4 to 48.7, 35.5 to 49.7 and 39.8-54.3 mm among Boerboel litters. This large variation suggests that biparietal diameter is too variable within and among litters to be useful as a means of determining readiness for cesarean section. PMID- 29454299 TI - Congenital forms of diabetes: the beta-cell and beyond. AB - The majority of patients diagnosed with diabetes less than 6 months of age, and many cases diagnosed between 6 and 12 months of age, have a gene mutation that causes permanent or transient hyperglycemia. Recent research advances have allowed for the discovery of new causes of congenital diabetes, including genes involved in pancreatic development (GATA4, NKX2-2, MNX1) and monogenic causes of autoimmune dysregulation (STAT3, LRBA). Ongoing follow-up of patients with KCNJ11 and ABCC8 mutations has supported the safety and efficacy of sulfonylureas, as well as the use of insulin pumps and continuous glucose monitors in infants with insulin-requiring forms of monogenic diabetes. Future studies are needed to improve clinical care and outcomes for these patients and their families. PMID- 29454300 TI - Gold-copper bimetallic nanoparticles supported on nano P zeolite modified carbon paste electrode as an efficient electrocatalyst and sensitive sensor for determination of hydrazine. AB - In this report, a facile, efficient and low cost electrochemical sensor based on bimetallic Au-Cu nanoparticles supported on P nanozeolite modified carbon paste electrode (Au-Cu/NPZ/CPE) was constructed and its efficiency for determination of hydrazine in trace level was studied. For this purpose, agro waste material, stem sweep ash (SSA) was employed as the starting material (silica source) for the synthesis of nano P zeolite (NPZ). After characterization of the synthesized NPZ by analytical instruments (scanning electronic microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and Fourier transform infrared (FT-IR) spectroscopy), construction of Au-Cu/NPZ/CPE was performed by three steps procedure involving preparation of nano P zeolite modified carbon paste electrode (NPZ/CPE), introducing Cu+2 ions into nano zeolite structure by ion exchange and electrochemical reduction of Cu+2 ions upon applying constant potential. This procedure is followed by partial replacement of Cu by Au due to galvanic replacement reaction (GRR). The electrochemical properties of hydrazine at the surface of Au-Cu/NPZ/CPE was evaluated using cyclic voltammetry (CV), amperometry, and chronoamperometry methods in 0.1 M phosphate buffer solution (PBS). It was found that the prepared sensor has higher electrocatalytic activity at a relatively lower potential compared to other modified electrodes including Au/NPZ/CPE, Cu/NPZ/CPE, Au-Cu/CPE and etc. Moreover, the proposed electrochemical sensor presented the favorable analytical properties for determination of hydrazine such as low detection limit (0.04 uM), rapid response time (3 s), wide linear range (0.01-150 mM), and high sensitivity (99.53 uA mM-1) that are related to the synergic effect of bimetallic of Au-Cu, porous structure and enough surface area of NPZ. In addition, capability of Au-Cu/NPZ/CPE sensor was successfully tested in real samples with good accuracy and precision. PMID- 29454301 TI - Heteroassembled gold nanoparticles with sandwich-immunoassay LSPR chip format for rapid and sensitive detection of hepatitis B virus surface antigen (HBsAg). AB - This study aimed to develop a more sensitive method for the detection of hepatitis B surface antigen (HBsAg) using heteroassembled gold nanoparticles (AuNPs). A single layered localized surface plasmon resonance (LSPR) chip format was developed with antigen-antibody reaction-based detection symmetry using AuNPs, which detected HBsAg at 10 pg/mL. To further improve the detection limit, a modified detection format was fabricated by fixing a secondary antibody (to form a heteroassembled sandwich format) to the AuNP monolayer, which enhanced the detection sensitivity by about 100 times. The developed heteroassembled AuNPs sandwich-immunoassay LSPR chip format was able to detect as little as 100 fg/mL of HBsAg within 10-15 min. In addition, the heteroassembled AuNPs sandwich immunoassay LSPR chip format did not show any non-specific binding to other tested antigens, including alpha fetoprotein (AFP), C-reactive protein (CRP), and prostate-specific antigen (PSA). These findings confirm that the proposed detection strategy of heteroassembled AuNPs sandwich-immunoassay LSPR chip format may provide a new platform for early diagnosis of various human diseases.

AB - PURPOSE: Obesity results in decreased lung function and increased inflammation. Moderate aerobic exercise (AE) reduced lung inflammation and remodeling in a variety of respiratory disease models. Therefore, this study investigated whether AE can attenuate a diet-induced obesity respiratory phenotype; including airway hyper-responsiveness (AHR), remodeling and inflammation. METHODS: Sixty C57Bl/6 male mice were distributed into four groups: control lean (CL), exercise lean (EL), obese (O) and obese exercise (OE) groups (2 sets of 7 and 8 mice per group; n = 15). A classical model of diet-induced obesity (DIO) over 12 weeks was used. AE was performed 60 min/day, 5 days/week for 5 weeks. Airway hyperresponsiveness (AHR), lung inflammation and remodeling, adipokines and cytokines in bronchoalveolar lavage (BAL) was determined. RESULTS: A high fat diet over 18 weeks significantly increased body weight (p < .0001). Five weeks of AE significantly reduced both AHR and pulmonary inflammation. AHR in obese mice that exercised was reduced at the basal level (p < .05), vehicle (PBS) (p < .05), 6.25 MCh mg/mL (p < .05), 12.5 MCh mg/mL (p < .01), 25 MCh mg/mL (p < .01) and 50 MCh mg/mL (p < .05). Collagen (p < .001) and elastic (p < .001) fiber deposition in airway wall and also smooth muscle thickness (p < .001) were reduced. The number of neutrophils (p < .001), macrophages (p < .001) and lymphocytes (p < .01) were reduced in the peribronchial space as well as in the BAL: lymphocytes (p < .01), macrophages (p < .01), neutrophils (p < .001). AE reduced obesity markers leptin (p < .001), IGF-1 (p < .01) and VEGF (p < .001), while increased adiponectin (p < .01) in BAL. AE also reduced pro-inflammatory cytokines in the BAL: IL-1beta (p < .001), IL-12p40 (p < .001), IL-13 (p < .01), IL-17 (p < .001, IL-23 (p < .05) and TNF-alpha (p < .05), and increased anti-inflammatory cytokine IL-10 (p < .05). CONCLUSIONS: Aerobic exercise reduces high fat diet-induced obese lung phenotype (AHR, pulmonary remodeling and inflammation), involving anti-inflammatory cytokine IL-10 and adiponectin. PMID- 29454304 TI - First and second eye cataract surgery and driver self-regulation among older drivers with bilateral cataract: a prospective cohort study. AB - BACKGROUND: Driving a car is the most common form of transport among the older population. Common medical conditions such as cataract, increase with age and impact on the ability to drive. To compensate for visual decline, some cataract patients may self-regulate their driving while waiting for cataract surgery. However, little is known about the self-regulation practices of older drivers throughout the cataract surgery process. The aim of this study is to assess the impact of first and second eye cataract surgery on driver self-regulation practices, and to determine which objective measures of vision are associated with driver self-regulation. METHODS: Fifty-five older drivers with bilateral cataract aged 55+ years were assessed using the self-reported Driving Habits Questionnaire, the Mini-Mental State Examination and three objective visual measures in the month before cataract surgery, at least one to three months after first eye cataract surgery and at least one month after second eye cataract surgery. Participants' natural driving behaviour in four driving situations was also examined for one week using an in-vehicle monitoring device. Two separate Generalised Estimating Equation logistic models were undertaken to assess the impact of first and second eye cataract surgery on driver-self-regulation status and which changes in visual measures were associated with driver self-regulation status. RESULTS: The odds of being a self-regulator in at least one driving situation significantly decreased by 70% after first eye cataract surgery (OR: 0.3, 95% CI: 0.1-0.7) and by 90% after second eye surgery (OR: 0.1, 95% CI: 0.1 0.4), compared to before first eye surgery. Improvement in contrast sensitivity after cataract surgery was significantly associated with decreased odds of self regulation (OR: 0.02, 95% CI: 0.01-0.4). CONCLUSIONS: The findings provide a strong rationale for providing timely first and second eye cataract surgery for older drivers with bilateral cataract, in order to improve their mobility and independence. PMID- 29454305 TI - Psychotropic and anti-dementia treatment in elderly persons with clinical signs of dementia with Lewy bodies: a cross-sectional study in 40 nursing homes in Sweden. AB - BACKGROUND: Elderly persons with a dementia diagnosis often suffer from different neuropsychiatric symptoms (NPS) such as delusions, hallucinations, depression, anxiety, irritability and agitation. Currently, the medical treatment for NPS consists mostly of psychotropic medication such as hypnotics/sedatives, anxiolytics and antipsychotics. In elderly persons with dementia, usage of antipsychotics is less appropriate because of the risk of side effects such as parkinsonism, rapid cognitive decline, cerebrovascular events and finally mortality. Furthermore, elderly persons with dementia with Lewy bodies (DLB) are often hypersensitive to antipsychotics with numerous serious adverse events such as somnolence, sedation, extra-pyramidal symptoms, delirium and increased mortality. The aim of this study was to investigate the usage of psychotropics with a focus on antipsychotics and anti-dementia medication (according to the Anatomical Therapeutic Chemical Classification System) in elderly persons with clinical signs of DLB living in dementia nursing homes (NHs) in Sweden. METHODS: Between 2012 and 2013, we applied a specially designed questionnaire that covered the clinical DLB features according to the consensus criteria of DLB. We also collected computerized medical lists from the Swedish National Medication Dispensing System from the same period. All dementia NHs (n = 40) in Malmo, the third largest city in Sweden, were covered. Of 650 eligible residents, 610 (94%) were included with 576 medical lists. The mean age was 86 years and 76% were women. RESULTS: Treatment with antipsychotics was seen in 22% of residents, hypnotics/sedatives in 41%, antidepressants in 50% and anxiolytics in 58%. We also found an increasing usage of antipsychotics from 25% to 43% in residents with the increasing number of DLB features. Anti-dementia medications were found in 45% of the elderly with a dementia diagnosis. However, residents with two or more DLB features had less anti-dementia medication (37%) than the rest of the dementia-diagnosed NH residents (62-69%). CONCLUSIONS: Residents with 2-4 DLB clinical features in Swedish NHs receive an unfavourable medical treatment with high antipsychotic usage and insufficient anti-dementia medication. These findings show the importance of identifying elderly persons with DLB features more effectively and improving the collaboration with nursing care to provide better medical prescription. PMID- 29454306 TI - RECORD-4 multicenter phase 2 trial of second-line everolimus in patients with metastatic renal cell carcinoma: Asian versus non-Asian population subanalysis. AB - BACKGROUND: RECORD-4 assessed everolimus in patients with metastatic renal cell carcinoma (mRCC) who progressed after 1 prior anti-vascular endothelial growth factor (VEGF) or cytokine and reinforced the clinical benefit of second-line everolimus. Because of the high percentage of patients from China enrolled in RECORD-4 (41%) and some reported differences in responses to certain targeted agents between Chinese and Western patients, this subanalysis evaluated outcomes in Asian versus non-Asian patients. METHODS: RECORD-4 enrolled patients with clear cell mRCC into 3 cohorts based on prior first-line therapy: sunitinib, other anti-VEGF (sorafenib, bevacizumab, pazopanib, other), or cytokines. Patients received everolimus 10 mg/d until progression of disease (RECIST, v1.0) or intolerance. Primary end point was progression-free survival per investigator review. Data cutoff was Sept 1, 2014. RESULTS: Among Asian (n = 55) versus non Asian (n = 79) patients, 98% versus 84% had good/intermediate MSKCC prognosis; 73% versus 65% were men, and 85% versus 73% were < 65 years of age. All (100%) Asian patients were of Chinese ethnicity. Median duration of exposure was 5.5 mo for Asian and 6.0 mo for non-Asian patients. Among Asian versus non-Asian patients, median progression-free survival (months) was 7.4 versus 7.8 overall, 7.4 versus 4.0 with prior sunitinib, and 5.7 versus 9.2 with prior other anti VEGFs. Clinical benefit rate was similar between populations: 74.5% (95% CI 61.0 85.3) for Asian patients and 74.7% (95% CI 63.6-83.8) for non-Asian patients. Most patients achieved stable disease as best overall response (Asian, 63.6%; non Asian, 69.6%). Overall rate of grade 3/4 adverse events appeared similar for Asian (58%) and non-Asian patients (54%). CONCLUSIONS: This RECORD-4 subanalysis demonstrated comparable efficacy and adverse event profiles of second-line everolimus in Asian and non-Asian patients. Efficacy and safety outcomes by prior therapy should be interpreted with caution because of small patient numbers in some subpopulations.

PMID- 29454307 TI - Association between residual teeth number in later life and incidence of dementia: A systematic review and meta-analysis. AB - BACKGROUND: It has been suggested that tooth loss in later life might increase dementia incidence. The objective of this analysis is to systematically review the current evidence on the relationship between the number of remaining teeth and dementia occurrence in later life. METHODS: A search of multiple databases of scientific literature was conducted with relevant parameters for articles published up to March 25th, 2017. Multiple cohort studies that reported the incidence of dementia and residual teeth in later life were found with observation periods ranging from 2.4 to 32 years. Random-effects pooled odds ratios (OR) and 95% confidence intervals (CI) were estimated to examine whether high residual tooth number in later life was associated with a decreased risk of dementia. Heterogeneity was measured by I2. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system was used to assess the overall quality of evidence. RESULTS: The literature search initially yielded 419 articles and 11 studies (aged 52 to 75 at study enrollment, n = 28,894) were finally included for analysis. Compared to the low residual teeth number group, the high residual teeth number group was associated with a decreased risk of dementia by approximately 50% (pooled OR = 0.483; 95% CI 0.315 to 0.740; p < 0.001; I2 = 92.421%). The overall quality of evidence, however, was rated as very low. CONCLUSION: Despite limited scientific strength, the current meta-analysis reported that a higher number of residual teeth was associated with having a lower risk of dementia occurrence in later life. PMID- 29454308 TI - The unique evolutionary pattern of the Hydroxyproline-rich glycoproteins superfamily in Chinese white pear (Pyrus bretschneideri). AB - BACKGROUND: The hydroxyproline-rich glycoprotein (HRGP) superfamily, comprising three families (arabinogalactan-proteins, AGPs; extensins, EXTs; proline-rich proteins, PRPs), is a class of proline-rich proteins that exhibit high diversity and are involved in many aspects of plant biology. RESULTS: In this study, 838 HRGPs were identified from Chinese white pear (Pyrus bretschneideri) by searching for biased amino acid composition and conserved motifs. 405 HRGPs were derived from whole genome duplication (WGD) events which is suggested to be the major force of driving HRGPs expansion and the recent WGD event shared by apple and pear generated most duplicated HRGPs in pear. This duplication event drived the structural variation of the HRGPs encoding hydroxyproline (Hyp)-rich motifs. The rate of HRGPs evolution mainly impacted the Hyp-rich motifs even in chimeric HRGPs. During the evolution of 53 PRPs that are also typified by 7-deoxyloganetin glucosyltransferase-like genes, the duplication from PRP to non-PRP was indirectly modified by positive selection. These results suggested that the rate of HRGP evolution mainly influenced the Hyp-rich motifs even in chimeric HRGPs. The expression divergence of HRGPs was higher than that of other commonly duplicated genes. In pear pistil, 601 HRGPs exhibited expression, while in pear pollen, 285 HRGPs were expressed. The qPCR results revealed that Pbr036330.1 and Pbr010506.1 showed different expression profile in self-incompatibility of pear pistil. CONCLUSIONS: The researches indicated that WGD events was the main duplication type during the evolution of HRGPs, and the highly variable Hyp motifs might be accountable for the expansion, evolution and expression divergence of HRGPs and that this divergence may be responsible for the gain of new functions in plants. PMID- 29454309 TI - Perceptions about screening for prostate cancer using genetic lifetime risk assessment: a qualitative study. AB - BACKGROUND: Most health authorities do not recommend screening for prostate cancer with PSA tests in asymptomatic patients who are not at increased risk. However, opportunistic screening for prostate cancer is still wanted by many patients and it is widely used in primary care clinics, with potential for overdiagnosis and overtreatment. Better tools for risk assessment have been called for, to better target such opportunistic screening. Our aim was to explore perceptions about prostate cancer risk and subsequent opportunistic screening among patients who were not at increased risk of prostate cancer after a first PSA test plus a genetic lifetime risk assessment. METHODS: We undertook semi structured patient interviews with recording and verbatim transcription of interviews. Data were analysed thematically. RESULTS: Three themes were identified: uncertainty of the nature of prostate cancer; perceived benefits of testing; and conflicting public health recommendations. Prostate cancer was spoken of as an inescapable risk in older age. The aphorism "you die with it, not from it" was prominent in the interviews but patients focused on the benefits of testing now rather than the future risks associated with treatment relating to potential overdiagnosis. Many expressed frustration with perceived mixed messages about early detection of cancer, in which on one side men feel that they are encouraged to seek medical testing to act responsibly regarding the most common cancer disease in men, and on the other side they are asked to refrain from opportunistic testing for prostate cancer. Taken together, personal risks of prostate cancer were perceived as high in spite of a normal PSA test and a genetic lifetime risk assessment showing no increased risk. CONCLUSION: Patients saw prostate cancer risk as high and increasing with age. They focused on the perceived benefit of early detection using PSA testing. It was also commonly acknowledged that most cases are indolent causing no symptoms and not shortening life expectancy. There was a frustration with mixed messages about the benefit of early detection and risk of overdiagnosis. These men's genetic lifetime risk assessment showing no increased risk did not appear to influence current intentions to get PSA testing in the future. PMID- 29454310 TI - In vitro and in silico validation of CA3 and FHL1 downregulation in oral cancer. AB - BACKGROUND: Aberrant methylation is a frequent event in oral cancer. METHODS: In order to better characterize these alterations, a search for genes downregulated by aberrant methylation in oral squamous cell carcinoma (OSCC) was conducted through the mining of ORESTES dataset. Findings were further validated in OSCC cell lines and patients' samples and confirmed using TCGA data. Differentially expressed genes were identified in ORESTES libraries and validated in vitro using RT-PCR in HNSCC cell-lines and OSCC tumor samples. Further confirmation of these results was performed using mRNA expression and methylation data from The Cancer Genome Atlas (TCGA) data. RESULTS: From the set of genes selected for validation, CA3 and FHL1 were downregulated in 60% (12/20) and 75% (15/20) of OSCC samples, respectively, and in HNSCC cell lines. The treatment of cell lines JHU-13 and FaDu with the demethylating agent 5'-aza-dC was efficient in restoring CA3 and FHL1 expression. TCGA expression and methylation data on OSCC confirms the downregulation of these genes in OSCC samples and also suggests that expression of CA3 and FHL1 is probably regulated by methylation. The downregulation of CA3 and FHL1 observed in silico was validated in HNSCC cell lines and OSCC samples, showing the feasibility of integrating different datasets to select differentially expressed genes in silico. CONCLUSIONS: These results showed that the downregulation of CA3 and FHL1 data observed in the ORESTES libraries was validated in HNSCC cell lines and OSCC samples and in a large cohort of samples from the TCGA database. Moreover, it suggests that expression of CA3 and FHL1 could probably be regulated by methylation having an important role the oral carcinogenesis. PMID- 29454311 TI - Radiotherapy related skin toxicity (RAREST-01): Mepitel(r) film versus standard care in patients with locally advanced head-and-neck cancer. AB - BACKGROUND: The aim of the present trial is to investigate a new option of skin protection in order to reduce the rate of grade >= 2 skin toxicity in patients receiving radiotherapy alone or radiochemotherapy for locally advanced squamous cell carcinoma of the head-and-neck (SCCHN). METHODS / DESIGN: This is a randomized, active-controlled, parallel-group multi-center trial that compares the following treatments of radiation dermatitis in patients with head-and-neck cancer: Mepitel(r) Film (Arm A) vs. standard care (Arm B). The primary aim of this trial is to investigate the rate of patients experiencing grade >= 2 radiation dermatitis (according to Common Toxicity Criteria for Adverse Events (CTCAE) Version 4.03) until 50 Gy of radiotherapy. Evaluation until 50 Gy of radiotherapy has been selected as the primary endpoint, since up to 50 Gy, the irradiated volume includes the primary tumor and the bilateral cervical and supraclavicular lymph nodes, and, therefore, is similar in all patients. After 50 Gy, irradiated volumes are very individual, depending on location and size of the primary tumor, involvement of lymph nodes, and the treatment approach (definitive vs. adjuvant). In addition, the following endpoints will be evaluated: Time to grade 2 radiation dermatitis until 50 Gy of radiotherapy, rate of patients experiencing grade >= 2 radiation dermatitis during radio(chemo)therapy, rate of patients experiencing grade >= 3 skin toxicity during radio(chemo)therapy, adverse events, quality of life, and dermatitis-related pain. Administration of Mepitel(r) Film will be considered to be clinically relevant, if the rate of grade >= 2 radiation dermatitis can be reduced from 85% to 65%. DISCUSSION: If administration of Mepitel(r) Film instead of standard care will be able to significantly reduce the rate of grade >= 2 radiation dermatitis, it could become the new standard of skin care in patients irradiated for SCCHN.

PMID- 29454312 TI - Effects of a wide range of dietary forage-to-concentrate ratios on nutrient utilization and hepatic transcriptional profiles in limit-fed Holstein heifers. AB - BACKGROUND: Improving the efficiency of animal production is a relentless pursuit of ruminant producers. Energy utilization and partition can be affected by dietary composition and nutrient availability. Furthermore, the liver is the central metabolic intersection in cattle. However, the specific metabolic changes in the liver under conditions of limit-feeding remain unclear and require further study. The present study aimed to elucidate the effects of a wide range of dietary forage:concentrate ratios (F:C) on energy utilization, and identify potential changes in molecular metabolism by analyzing hepatic transcriptional profiles. Twenty-four half-sib Holstein heifers were fed four F:C diets (20:80, 40:60, 60:40, and 80:20 on a dry matter basis), with similar intake levels of metabolizable energy (ME) and crude protein. Liver biopsy samples were obtained and RNA sequencing was conducted to identify the hepatic transcriptomic changes. Moreover, the ruminal fermentation profiles, growth characteristics, and levels of metabolites in the liver and plasma of the heifers were monitored. RESULTS: The proportion of acetate showed a linear increase (P < 0.01) with increasing dietary forage levels, whereas the proportion of propionate showed a linear decline (P <= 0.01). Lower levels of average daily gain and feed efficiency (P < 0.01) were observed in heifers fed high levels of forage, with a significant linear response. Using the Short Time-series Expression Miner software package, the expression trends of significant differentially expressed genes (DEGs) were generally divided into 20 clusters, according to their dynamic expression patterns. Functional classification analysis showed that lipid metabolism (particularly cholesterol and steroid metabolism which were in line with the cholesterol content in the liver and plasma) was significantly increased with increasing dietary forage levels and slightly reduced by the 80% forage diet. Nine DEGs were enriched in the related pathways, namely HMGCS1, HMGCR, MSMO1, MVK, MVD, IDI1, FDPS, LSS, and DHCR7. CONCLUSIONS: The ruminal fermentation and feed efficiency results suggest that different mechanisms of energy utilization might occur in heifers fed different F:C diets with similar levels of ME intake. Increased cholesterol synthesis from acetate might be responsible for the reduced efficiency of energy utilization in heifers fed high-forage diets. PMID- 29454313 TI - StructRNAfinder: an automated pipeline and web server for RNA families prediction. AB - BACKGROUND: The function of many noncoding RNAs (ncRNAs) depend upon their secondary structures. Over the last decades, several methodologies have been developed to predict such structures or to use them to functionally annotate RNAs into RNA families. However, to fully perform this analysis, researchers should utilize multiple tools, which require the constant parsing and processing of several intermediate files. This makes the large-scale prediction and annotation of RNAs a daunting task even to researchers with good computational or bioinformatics skills. RESULTS: We present an automated pipeline named StructRNAfinder that predicts and annotates RNA families in transcript or genome sequences. This single tool not only displays the sequence/structural consensus alignments for each RNA family, according to Rfam database but also provides a taxonomic overview for each assigned functional RNA. Moreover, we implemented a user-friendly web service that allows researchers to upload their own nucleotide sequences in order to perform the whole analysis.

PMID- 29454314 TI - A prospective study to investigate the role of serial serum mesothelin in monitoring mesothelioma. AB - BACKGROUND: Radiological monitoring of malignant pleural mesothelioma (MPM) using modified RECIST criteria is limited by low sensitivity and inter-observer variability. Serial serum mesothelin measurement has shown utility in the assessment of treatment response during chemotherapy but has never been assessed in the longer term follow up of patients. METHODS: This is a single centre study of consecutive patients diagnosed with MPM who received chemotherapy or best supportive care (BSC). Serum mesothelin measurements with paired 6 monthly CT scans were performed following the completion of chemotherapy, or from baseline in the BSC group. Changes in mesothelin were correlated with radiological progression and overall survival. RESULTS: Forty-one patients with MPM were recruited and followed up for a minimum of 12 months (range 12-21 months). The majority of patients (n = 23) received chemotherapy with pemetrexed and cisplatin. Across the cohort a 10% rise in serum mesothelin could predict radiological progression with a sensitivity of 96% (IQR; 79-100) and specificity of 74% (IQR; 50-91). Sensitivity fell to 80% in sarcomatoid only disease. Patients with a rising mesothelin at 6 months had significantly worse overall survival (175 days) compared to stable/falling levels (448 days) (p = 0.003). CONCLUSIONS: This is the first study to assess serum mesothelin's ability to detect progression of MPM following chemotherapy or during BSC. A 10% rise in serum mesothelin level showed excellent sensitivity at predicting progressive disease. Mesothelin measurement has several advantages over serial CT imaging including reducing hospital visits and cost. PMID- 29454315 TI - Prevalence and correlates of positive mental health in Chinese adolescents. AB - BACKGROUND: Studies investigating the prevalence of positive mental health and its correlates are still scarce compared to the studies on mental disorders, although there is growing interest of assessing positive mental health in adolescents. So far, no other study examining the prevalence and determinants of positive mental health in Chinese adolescents has been found. The purpose of this study was to assess the prevalence and correlates of positive mental health in Chinese adolescents. METHODS: This cross-sectional study used a questionnaire including Mental Health Continuum-Short Form (MHC-SF) and items regarding multiple aspects of adolescent life. The sample involved a total of 5399 students from grade 8 and 10 in Weifang, China. Multivariate Logistic regression analyses were performed to evaluate the associations between potential indicators regarding socio-economic situations, life style, social support and school life and positive mental health and calculate odds ratios and 95% confidence intervals. RESULTS: More than half (57.4%) of the participants were diagnosed as flourishing. The correlated factors of positive mental health in regression models included gender, perceived family economy, the occurrence of sibling(s), satisfaction of self-appearance, physical activity, sleep quality, stress, social trust, desire to learn, support from teachers and parents as well as whether being bullied at school (OR ranging from 1.23 to 2.75). The Hosmer-Lemeshow p value for the final regression model (0.45) indicated adequate model fit. CONCLUSION: This study gives the first overview on prevalence and correlates of positive mental health in Chinese adolescents. The prevalence of positive mental health in Chinese adolescents is higher than reported in most of the previous studies also using MHC-SF. Our findings suggest that adolescents with advantageous socio-economic situations, life style, social support and school life are experiencing better positive mental health than others. PMID- 29454316 TI - The theoretical and empirical basis of a BioPsychoSocial (BPS) risk screener for detection of older people's health related needs, planning of community programs, and targeted care interventions. AB - BACKGROUND: This study introduces the conceptual basis and operational measure, of BioPyschoSocial (BPS) health and related risk to better understand how well older people are managing and to screen for risk status. The BPS Risk Screener is constructed to detect vulnerability at older ages, and seeks to measure dynamic processes that place equal emphasis on Psycho-emotional and Socio-interpersonal risks, as Bio-functional ones. We validate the proposed measure and describe its application to programming. METHODS: We undertook a quantitative cross-sectional, psychometric study with n = 1325 older Singaporeans, aged 60 and over. We adapted the EASYCare 2010 and Lubben Social Network Scale questionnaires to help determine the BPS domains using factor analysis from which we derive the BPS Risk Screener items. We then confirm its structure, and test the scoring system. The score is initially validated against self-reported general health then modelled against: number of falls; cognitive impairment; longstanding diseases; and further tested against service utilization (linked administrative data). RESULTS: Three B, P and S clusters are defined and identified and a BPS managing score ('doing' well, or 'some', 'many', and 'overwhelming problems') calculated such that the risk of problematic additive BPS effects, what we term health 'loads', are accounted for. Thirty-five items (factor loadings over 0.5) clustered into three distinct B, P, S domains and were found to be independently associated with self-reported health: B: 1.99 (1.64 to 2.41), P: 1.59 (1.28 to 1.98), S: 1.33 (1.10 to 1.60). The fit improved when combined into the managing score 2.33 (1.92 to 2.83, < 0.01). The score was associated with mounting risk for all outcomes. CONCLUSIONS: BPS domain structures, and the novel scoring system capturing dynamic BPS additive effects, which can combine to engender vulnerability, are validated through this analysis. The resulting tool helps render clients' risk status and related intervention needs transparent. Given its explicit and empirically supported attention to P and S risks, which have the potential to be more malleable than B ones, especially in the older old, this tool is designed to be change sensitive. PMID- 29454317 TI - Oxidative damage and response to Bacillus Calmette-Guerin in bladder cancer cells expressing sialyltransferase ST3GAL1. AB - BACKGROUND: Treatment with Bacillus Calmette-Guerin (BCG) is the gold standard adjuvant immunotherapy of non-muscle invasive bladder cancer (NMIBC), although it fails in one third of the patients. NMIBC expresses two tumor-associated O-linked carbohydrates: the disaccharide (Galbeta1,3GalNAc) Thomsen-Friedenreich (T) antigen, and its sialylated counterpart (Siaalpha2,3Galbeta1,3GalNAc) sialyl-T (sT), synthesized by sialyltransferase ST3GAL1, whose roles in BCG response are unknown. METHODS: The human bladder cancer (BC) cell line HT1376 strongly expressing the T antigen, was retrovirally transduced with the ST3GAL1 cDNA or with an empty vector, yielding the cell lines HT1376sT and HT1376T, that express, respectively, either the sT or the T antigens. Cells were in vitro challenged with BCG. Whole gene expression was studied by microarray technology, cytokine secretion was measured by multiplex immune-beads assay. Human macrophages derived from blood monocytes were challenged with the secretome of BCG-challenged BC cells. RESULTS: The secretome from BCG-challenged HT1376sT cells induced a stronger macrophage secretion of IL-6, IL-1beta, TNFalpha and IL-10 than that of HT1376T cells. Transcriptomic analysis revealed that ST3GAL1 overexpression and T/sT replacement modulated hundreds of genes. Several genes preserving genomic stability were down-regulated in HT1376sT cells which, as a consequence, displayed increased sensitivity to oxidative damage. After BCG challenge, the transcriptome of HT1376sT cells showed higher susceptibility to BCG modulation than that of HT1376T cells. CONCLUSIONS: High ST3GAL1 expression and T/sT replacement in BCG challenged-BC cancer cells induce a stronger macrophage response and alter the gene expression towards genomic instability, indicating a potential impact on BC biology and patient's response to BCG. PMID- 29454318 TI - Points-based physical activity: a novel approach to facilitate changes in body composition in inactive women with overweight and obesity. AB - BACKGROUND: Physical activity (PA) interventions for the promotion of weight management may benefit from increased choice and flexibility to overcome commonly perceived barriers to PA. The aim of this study was to investigate the effects of a novel "points-based" approach to PA on body composition in inactive women, who are overweight or obese. METHODS: Seventy-six overweight or obese, inactive women were randomly allocated to one of three conditions: 'Points-based' PA (PBPA; 30 "PA points"*week- 1), Structured exercise (StructEx; 150 min moderate-intensity exercise*week- 1) or control (CONT; continue habitual inactive lifestyle) for a 24-week intervention. PA points for activities were adapted from MET values, and 30 points was equivalent to 150 min of brisk walking. Measures of body composition (dual-energy x-ray absorptiometry) and anthropometry were obtained at weeks 0, 4, 12 and 24. Self-report activities were recorded weekly, with objective measures of PA (tri-axial accelerometry) and self-report measures of food intake obtained at weeks 0 and 24. RESULTS: Fifty-eight women completed the study and provided data for primary outcomes. Of these, n = 41 and n = 19 provided data for food intake and objectively assessed PA. Mixed-design ANOVAs demonstrated that those in PBPA achieved a significant weight-loss at 24 weeks of - 3.3 +/- 5.9 kg (- 3.4 +/- 7.1%, p = 0.004). Waist circumference was reduced in PBPA at 24 weeks (- 2.8 +/- 4.6 cm), compared with CONT (+ 2.1 +/- 6.6 cm, p = 0.024). There was a trend for greater reductions in fat mass for those in PBPA vs. CONT (- 2.3 +/- 4.6 kg vs. + 0.1 +/- 2.0 kg, p = 0.075). Android fat was reduced in PBPA at both 12 weeks (- 6.1 +/- 12.6%, p = 0.005) and 24 weeks (- 10.1 +/- 18.4%, p = 0.005), while there was a trend for greater reductions in visceral adipose tissue in PBPA (- 5.8 +/- 26.0%) vs. CONT at 24 weeks (+ 7.8 +/- 18.3%, p = 0.053). Body composition, body weight and waist circumference were unchanged in StructEx. There were trends for increases in light-activity and reductions in sedentary time in PBPA. There was a trend for a reduction in daily energy intake of - 445 +/- 564 kcal (p = 0.074), and a significant reduction in daily fat intake (p = 0.042) in PBPA. CONCLUSION: A "points-based" approach to physical activity appears to be an effective strategy for inducing modest reductions in body weight and body fat in inactive women with overweight and obesity. TRIAL REGISTRATION: NCT02020239 . Registered 12th December 2013. PMID- 29454319 TI - Treatment of upper tract urothelial carcinoma with ureteroscopy and thulium laser: a retrospective single center study. AB - BACKGROUND: Treatment with the combination of ureteroscopy and thulium laser ablation may provide an alternative to radical nephroureterectomy (RNU) for patients with upper tract urothelial carcinoma (UTUC). The purpose of this study was to investigate the efficacy and safety of this technique. METHODS: We performed a retrospective review of the data for patients who were treated surgically for upper tract urothelial carcinoma in a single center. It included 32 patients treated by endoscopic thulium laser resection and 107 patients treated by radical nephroureterectomy (RNU). We compared the data of patient sex, age at diagnosis, location of carcinoma, length of hospitalization, tumor site, size, grade, recurrence, preoperative creatinine and postoperative creatinine in two groups. Patients were examined by ureteroscopy every 3 months during the first year after surgery, then every 6 months each year. RESULTS: All 32 patients were treated successfully, among which 6 were operated by a flexible ureteroscope. The average tumor size was 13 +/- 7 mm in diameter. The tumor was rated as low grade in 27 patients and high grade in 5 patients. Ureteral stricture developed in 4 patients 3 months later after surgery, but the stricture was succesfully treated through endoscopic dilation. Seven patients had tumor recurrence, 3 of which underwent nephroureterectomy during the follow-up. Postoperative creatinine levels (umol/L) were respectively 89 +/- 7.5 in laser group and 123 +/- 15.4 in RNU group (p < 0.01). Length of hospitalization was respectively 3.6 +/- 1.9 and 8.6 +/- 2.4 days (p < 0.01). Local or bladder recurrence rate of thulium laser group and RNU group was respectively 21.9 and 13.1% (p < 0.01). CONCLUSIONS: Thulium laser group is associated with a less loss of renal function, a shorter length of hospitalization, but a higher rate of tumor recurrence. Thulium laser therapy combined with ureteroscopic treatment can be considered as an acceptable treatment for selected cases of UTUC. Lifetime intensive surveillance is necessary. PMID- 29454320 TI - Obesity and caries in four-to-six year old English children: a cross-sectional study. AB - BACKGROUND: Obesity and caries are common conditions in childhood and can have significant implications on children's wellbeing. Evidence into their association remains conflicting. Furthermore, studies examining the ssociation between obesity and caries commonly focus on individual-level determinants. The present study aimed to examine the association between obesity and caries in young English children and to determine the impact of deprivation and area-level characteristics on the distribution of the two conditions. METHODS: This was a cross-sectional study among children in Plymouth city aged four-to-six years. Anthropometric measurements included weight and height (converted to Body Mass Index centiles and z-scores), and waist circumference. Caries was assessed by using the sum of the number of teeth that were decayed, missing or filled. A questionnaire was used to obtain information on children's demographic characteristics, oral hygiene, and dietary habits. The impact of deprivation on anthropometric variables and caries was determined using Linear and Poisson regression models, respectively. Multiple logistic regression was used to assess the association between different anthropometric measures and caries. Logistic regression models were also used to examine the impact of several demographic characteristics and health behaviours on the presence of obesity and caries. RESULTS: The total sample included 347 children aged 5.10 +/- 0.31 (mean +/- SD). Deprivation had a significant impact on caries and BMI z-scores (p < 0.05). Neither BMI- nor waist circumference z-scores were shown to be significantly associated with dental caries. Among the neighbourhood characteristics examined, the percentage of people dependent on benefits was found to have a significant impact on caries rates (p < 0.05). Household's total annual income was inversely related to caries risk and parental educational level affected children's tooth brushing frequency. CONCLUSIONS: No associations between any measure of obesity and caries were found. However, deprivation affected both obesity and caries, thus highlighting the need to prioritise disadvantaged children in future prevention programmes. PMID- 29454321 TI - Safety and efficacy of temsirolimus as second line treatment for patients with recurrent bladder cancer. AB - BACKGROUND: Bladder cancer is the 7th cause of death from cancer in men and 10th in women. Metastatic patients have a poor prognosis with a median overall survival of 14 months. Until recently, vinflunine was the only second-line chemotherapy available for patients who relapse. Deregulation of the PI3K/AKT/mTOR pathway was observed in more than 40% of bladder tumors and suggested the use of mTOR as a target for the treatment of urothelial cancers. METHODS: This trial assessed the efficacy of temsirolimus in a homogenous cohort of patients with recurrent or metastatic bladder cancer following first-line chemotherapy. Efficacy was measured in terms of non-progression at two months according to the RECIST v1.1 criteria. Based on a two-stage optimal Simon's design, 15 non-progressions out of 51 evaluable patients were required to claim efficacy. Patients were treated at a weekly dose of 25 mg IV until progression, unacceptable toxicities or withdrawal. RESULTS: Among the 54 patients enrolled in the study between November 2009 and July 2014, 45 were assessable for the primary efficacy endpoint. A total of 22 (48.9%) non-progressions were observed at 2 months with 3 partial responses and 19 stable diseases. Remarkably, 4 patients were treated for more than 30 weeks. Fifty patients experienced at least a related grade1/2 (94%) and twenty-eight patients (52.8%) a related grade 3/4 adverse event. Eleven patients had to stop treatment for toxicity. This led to recruitment being halted by an independent data monitoring committee with regard to the risk-benefit balance and the fact that the primary objective was already met. CONCLUSIONS: While the positivity of this trial indicates a potential benefit of temsirolimus for a subset of bladder cancer patients who are refractory to first line platinum-based chemotherapy, the risk of adverse events associated with the use of this mTOR inhibitor would need to be considered when such an option is envisaged in this frail population of patients. It also remains to identify patients who will benefit the most from this targeted therapy.

PMID- 29454322 TI - Using eHealth to engage and retain priority populations in the HIV treatment and care cascade in the Asia-Pacific region: a systematic review of literature. AB - BACKGROUND: The exponential growth in the reach and development of new technologies over the past decade means that mobile technologies and social media play an increasingly important role in service delivery models to maximise HIV testing and access to treatment and care. This systematic review examines the impact of electronic and mobile technologies in medical care (eHealth) in the linkage to and retention of priority populations in the HIV treatment and care cascade, focussing on the Asia-Pacific region. METHODS: The review was informed by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement from the Cochrane Collaboration guidelines. Both grey and published scientific literature from five different databases were searched for all original articles in English published from 2010 to 2017. Studies conducted outside the Asia-Pacific region or not including HIV priority populations were excluded. The methodological quality of studies included in the review was assessed using the Quality Assessment Tool for Quantitative Studies. RESULTS: The database search identified 7309 records. Of the 224 peer-reviewed articles identified for full text review, 16 studies from seven countries met inclusion criteria. Six cross sectional studies found evidence to support the use of eHealth, via text messages, instant messaging, social media and health promotion websites, to increase rates of HIV testing and re-testing among men who have sex with men (MSM). Evidence regarding the efficacy of eHealth interventions to improve antiretroviral treatment (ART) adherence was mixed, where one randomised controlled trial (RCT) showed significant benefit of weekly phone call reminders on improving ART adherence. Three further RCTs found that biofeedback eHealth interventions that provided estimated ART plasma concentration levels, showed promising results for ART adherence. CONCLUSIONS: This review found encouraging evidence about how eHealth can be used across the HIV treatment and care cascade in the Asia-Pacific region, including increasing HIV testing and re-testing in priority populations as well as ART adherence. eHealth interventions have an important role to play in the movement towards the end of AIDS, particularly to target harder-to-reach HIV priority populations, such as MSM. PMID- 29454323 TI - Autonomy and infant feeding decision-making among teenage mothers in a rural and urban setting in KwaZulu-Natal, South Africa. AB - BACKGROUND: The nutritional status of infants born to teenage mothers can be sub optimal compared to those born to older mothers. One contributing factor is inappropriate feeding practices adopted by teenage mothers. Little is known about how infant feeding decisions are made among teenage mothers, particularly in under resourced settings. In this study we prospectively explored autonomy and infant feeding decision-making among teenage mothers in a rural and urban setting in KwaZulu-Natal, South Africa. METHODS: This study adopted a qualitative longitudinal design. Thirty pregnant participants were recruited to the study cohort, from the catchment area of two hospitals (one urban and one rural). Participants were purposively selected to include teenagers, HIV positive, and working pregnant women. We report findings from ten teenage mothers, aged between 15 and 19 years, who participated in the larger cohort (n = 5 rural; n = 5 urban). Monthly in-depth interviews were conducted with participating mothers for 6 months starting 2 weeks after delivery. All interviews were conducted in the local language, transcribed verbatim and translated into English. Data was coded using NVivo v10 and framework analysis was used. RESULTS: Findings from this study showed that teenage mothers had knowledge about recommended feeding practices. However, our findings suggest that these mothers were not involved in infant feeding decisions once they were at home, because infant feeding decision making was a role largely assumed by older mothers in the family. Further, the age of the mother and financial dependency diminished her autonomy and ability to influence feeding practices or challenge incorrect advice given at home. Most feeding advice shared by family members was inappropriate, leading to poor infant feeding practices among teenage mothers. Returning to school and fear of breastfeeding in public were also barriers to exclusive breastfeeding. CONCLUSION: Teenage mothers had a limited role in the infant feeding decision making process. Health workers have an important role to play in ensuring that knowledge about infant feeding is shared with the mother's family where infant feeding choices are made. This will improve support for teenage mothers, and may also positively impact on the nutritional status of children. PMID- 29454324 TI - Investigation of the anti-cataractogenic mechanisms of curcumin through in vivo and in vitro studies. AB - BACKGROUND: Cataract is the leading cause of blindness in elderly people worldwide, especially in developing countries. Studies to identify strategies that can prevent or retard cataract formation are urgently required. This study aimed to investigate the potential mechanism of the cytoprotective effects of curcumin in in vivo and in vitro experiments. METHODS: Male Wistar rats were randomly divided into three groups: the control group, the model group (administered 20 MUmol/kg sodium selenite), and the curcumin group (pretreated with 75 mg/kg body weight curcumin 24 h prior to the administration of sodium selenite). The expression levels of heat shock protein 70 (HSP70), the activities of 8-hydroxy-2-deoxyguanosine (8-OHdG), catalase (CAT), malondialdehyde (MDA), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px) were assessed by using RT-PCR assay and ELISA. In addition, the cell viability, cell apoptosis, and cell cycle were assessed using a CCK-8 assay and flow cytometry in in vitro studies, followed by RT-PCR analysis to identify the mRNA expression levels of caspase 3, Bcl-2 associated X (Bax), B-cell lymphoma 2 (Bcl-2), cyclooxygenase (Cox-2), c-met, and Slug. RESULTS: Cataract was successfully established in rats of the model group and the curcumin group through intraperitoneal injection of sodium selenite. The expression levels of HSP70 and the activities of 8-OHdG and MDA in the curcumin group were decreased compared with those in the model group, whereas the activities of CAT, SOD, and GSH-Px were significantly higher than those in the model group (P < 0.05). In the in vitro studies, the cell viability and cell apoptosis significantly increased and decreased, respectively, in the curcumin group compared with the model group. Correspondingly, the mRNA expression of caspase-3, Bax, and Cox-2 was lower in the curcumin group than in the model group (P < 0.05). CONCLUSIONS: This study suggested that curcumin attenuated selenite-induced cataract through the reduction of the intracellular production of reactive oxygen species and the protection of cells from oxidative damage. PMID- 29454325 TI - Latent tuberculosis infection and associated risk indicators in pastoral communities in southern Ethiopia: a community based cross-sectional study. AB - BACKGROUND: Research pertaining to the community-based prevalence of latent tuberculosis infection (LTBI) is important to understand the magnitude of this infection. This study was conducted to estimate LTBI prevalence and to identify associated risk factors in the Omo Zone of Southern Ethiopia. METHODS: A community-based cross-sectional study was conducted in six South Omo districts from May 2015 to February 2016. The sample size was allocated to the study districts proportional to their population sizes. Participants were selected using a multi-stage sampling approach. A total of 497 adult pastoralists were recruited. Blood samples were collected from the study participants and screened for LTBI using a U.S. Food and Drug Administration approved interferon-gamma release assay (IGRA). Logistic regression was used to model the likelihood of LTBI occurrence and to identify risk factors associated with LTBI. RESULTS: The prevalence of LTBI was 50.5% (95% CI: 46%, 55%) with no significant gender difference (49.8% among males versus 51.2% among females; Chi-square (chi2) = 0.10; P = 0.41) and marginally non-significant increasing trends with age (44.6% among those below 24 years and 59.7% in the age range of 45-64 years; chi2 = 6.91; P = 0.075). Being residence of the Dasanech District (adjusted odds ratio, AOR = 2.62, 95% CI: 1.30, 5.28; P = 0.007) and having a habit of eating raw meat (AOR = 2.89, 95% CI: 1.09, 7.66; P = 0.033) were significantly associated with an increased odds of being positive for LTBI. A large family size (size of 5 to 10) has significant protective effect against associated a reduced odds of being positive for LTBI compared to a family size of below 5 (AOR = 0.65, 95% CI: 0.42, 0.99; P = 0.045). CONCLUSIONS: A high prevalence of LTBI in the South Omo Zone raises the concern that elimination of TB in the pastoral communities of the region might be difficult. Screening for and testing individuals infected with TB, independent of symptoms, may be an effective way to minimize the risk of disease spread. PMID- 29454326 TI - Predictors of activity and participation across neurodegenerative conditions: a comparison of people with motor neurone disease, multiple sclerosis and Parkinson's disease. AB - BACKGROUND: Comparisons between neurological conditions have the potential to inform service providers by identifying particular areas of difficulty experienced by affected individuals. This study aimed to identify predictors of activity and participation in people with motor neurone disease (MND), people with multiple sclerosis (MS) and people with Parkinson's Disease (PD). METHODS: The Oxford Participation and Activities Questionnaire (Ox-PAQ) and Medical Outcomes Study 36-Item Short Form Survey (MOS SF-36) were administered by postal survey to 386 people with a confirmed diagnosis of MND, MS or PD. Data analyses focused on stepwise regression analyses in order to identify predictors of activity and participation in the three conditions assessed. RESULTS: Three hundred and thirty four participants completed the survey, a response rate of 86.5%. Regression analyses identified multiple predictors of activity and participation dependent on Ox-PAQ domain and disease group, the most prominent being social and physical functioning as measured by the MOS SF-36. CONCLUSIONS: Results indicate that the physical and social consequences of neurological illness are of greatest relevance to people experiencing the conditions assessed. Whilst the largely inevitable physical implications of disease take hold, emphasis should be placed on the avoidance of social withdrawal and isolation, and the maintenance of social engagement should become a significant priority. PMID- 29454328 TI - Cap-preserving SMILE Enhancement Surgery. AB - BACKGROUND: Different enhancement procedures have been suggested for reduction of residual refractive errors after SMILE. The aim of this study is to evaluate an improved cap-preserving technique for enhancement after SMILE (Re-SMILE). METHODS: A retrospective case series was conducted at Eye subspecialty center, Cairo, Egypt on 9 eyes with myopia or myopic astigmatism (spherical equivalent - 8.0 and - 12.0D). undergoing SMILE procedure and needed second interference. This was either because the more myopic meridian was more than - 10.0 D and therefore planned to have two-steps procedure (six eyes) or because of under correction needing enhancement (three eyes). Assessment after the primary SMILE procedure was conducted at 1 day, 1 week, 1 month and 3 months postoperatively. Assessment after Re-SMILE was conducted at 1 day, 1 week, 1 month, 3 months, 6 months and 1 year postoperatively. The assessments included full ophthalmic examination, objective and subjective refraction, and rotating Scheimpflug camera imaging. RESULTS: Preoperatively, the mean refractive spherical equivalent (MRSE) values were: - 9.36 +/- 0. 89. After primary SMILE it was - 2.18 +/- 0.71. After Re SMILE it was - 0.13 +/- 0.68. MRSE was significantly improved after both procedures (P < 0.01). The safety index of primary SMILE cases was 1.65 +/- 0.62 and for Re-SMILE 1.13 +/- 0.34 and the efficacy index was 1.14 +/- 0.24 after primary SMILE and 1.11 +/- 0.26 after Re-SMILE. CONCLUSION: Centered cap preserving Re-SMILE is an effective procedure in reducing residual refractive errors after primary SMILE in high myopes. PMID- 29454329 TI - Bilateral acute angle-closure glaucoma following tramadol subcutaneous administration. AB - BACKGROUND: To report a case of bilateral acute angle closure-glaucoma following the use of subcutaneous Tramadol. CASE PRESENTATION: A 42-year-old healthy man with unremarkable past medical and ocular history, was admitted to the Orthopedic Department for surgical treatment of a bilateral open fracture of the femur following a road accident. Three hoursafterTramadolsubcutaneous injection, the patient complained of a bilateral acute painful visual loss with persistent vomiting. An ocular examination showed bilateral acute angle-closure-glaucoma. The patient was treated with topical anti-glaucoma therapy and intravenous Mannitol 20%.After resolution of ocular hypertension attack, NdYag laser peripheral iridotomy was performed on both eyes. After a follow-up period of 7 days visual acuity improved to 20/20 in both eyes and intraocular pressure returned to normal levels. CONCLUSIONS: This case highlights the risk of developing bilateral acute angle-closure glaucoma after Tramadol administration. PMID- 29454327 TI - Peer support to improve diabetes care: an implementation evaluation of the Australasian Peers for Progress Diabetes Program. AB - BACKGROUND: Several studies have now demonstrated the benefits of peer support in promoting diabetes control. The aim of this study is to evaluate the implementation of a cluster randomised controlled trial of a group-based, peer support program to improve diabetes self-management and thereby, diabetes control in people with Type 2 Diabetes in Victoria, Australia. METHODS: The intervention program was designed to address four key peer support functions i.e. 1) assistance in daily management, 2) social and emotional support, 3) regular linkage to clinical care, and 4) ongoing and sustained support to assist with the lifelong needs of diabetes self-care management. The intervention participants attended monthly group meetings facilitated by a trained peer leader for 12 months. Data was collected on the intervention's reach, participation, implementation fidelity, groups' effectiveness and participants' perceived support and satisfaction with the intervention. The RE-AIM and PIPE frameworks were used to guide this evaluation. RESULTS: The trial reached a high proportion (79%) of its target population through mailed invitations. Out of a total of 441 eligible individuals, 273 (61.9%) were willing to participate. The intervention fidelity was high (92.7%). The proportion of successful participants who demonstrated a reduction in 5 years cardiovascular disease risk score was 65.1 and 44.8% in the intervention and control arm respectively. Ninety-four percent (94%) of the intervention participants stated that the program helped them manage their diabetes on a day to day basis. Overall, attending monthly group meetings provided 'a lot of support' to 57% and 'moderate' support to 34% of the participants. CONCLUSION: Peer support programs are feasible, acceptable and can be used to supplement treatment for patients motivated to improve behaviours related to diabetes. However, program planners need to focus on the participation component in designing future programs. The use of two evaluation frameworks allowed a comprehensive evaluation of the trial from the provider-, participant- and public health perspective. The learnings gained from this evaluation will guide and improve future implementation by improving program feasibility for adoption and acceptability among participants, and will ultimately increase the likelihood of program effectiveness for the participants.

AB - BACKGROUND: The aim of the study was to assess the association between chronic kidney disease (CKD) and obesity in predicting CKD among Chinese adults, distinguishing between 5 different adiposity indices: visceral fat index (VFI), percentage body fat (PBF), body mass index (BMI), waist circumference (WC) and waist-to-height ratio (WHtR). METHODS: A total of 29,516 participants aged 35 years or above were selected using a stratified multistage random sampling method across China during 2012-2015. CKD was defined as an estimated glomerular filtration (eGFR) < 60 ml/min/1.72m2. RESULTS: The overall weighted prevalence of CKD was 3.94% (3.62% in males and 4.25% in females). All five adiposity indices had significant negative correlations to eGFR (P < 0.05). The area under the ROC (receiver operating characteristic) curves (AUC) for PBF was almost significantly larger than the other adiposity indices (P < 0.001). In addition, PBF yielded the highest Youden index in identifying CKD (male: 0.15; female: 0.20). In the logistic analysis, PBF had the highest crude odds ratios (ORs) in both males (OR: 1.819, 95% CI 1.559-2.123) and females (OR: 2.268, 95% CI 1.980-2.597). After adjusted for age, smoking status, alcohol use, education level, marital status, rural vs. urban area, geographic regions, and diagnosis of hypertension, diabetes mellitus, myocardial infarction and stroke, the ORs on PBF remained significant for both genders (P < 0.05). CONCLUSIONS: Obesity is associated with an increased risk of CKD. Furthermore, PBF was a better predictor for identifying CKD than other adiposity indices (BMI, WC, WHtR, and VFI). PMID- 29454331 TI - The increasing importance of a continence nurse specialist to improve outcomes and save costs of urinary incontinence care: an analysis of future policy scenarios. AB - BACKGROUND: In an ageing population, it is inevitable to improve the management of care for community-dwelling elderly with incontinence. A previous study showed that implementation of the Optimum Continence Service Specification (OCSS) for urinary incontinence in community-dwelling elderly with four or more chronic diseases results in a reduction of urinary incontinence, an improved quality of life, and lower healthcare and lower societal costs. The aim of this study was to explore future consequences of the OCSS strategy of various healthcare policy scenarios in an ageing population. METHODS: We adapted a previously developed decision analytical model in which the OCSS new care strategy was operationalised as the appointment of a continence nurse specialist located within the general practice in The Netherlands. We used a societal perspective including healthcare costs (healthcare providers, treatment costs, insured containment products, insured home care), and societal costs (informal caregiving, containment products paid out-of-pocket, travelling expenses, home care paid out-of-pocket). All outcomes were computed over a three-year time period using two different base years (2014 and 2030). Settings for future policy scenarios were based on desk research and expert opinion. RESULTS: Our results show that implementation of the OSCC new care strategy for urinary incontinence would yield large health gains in community dwelling elderly (2030: 2592-2618 QALYs gained) and large cost-savings in The Netherlands (2030: health care perspective: ?32.4 Million - ?72.5 Million; societal perspective: ?182.0 Million - ?250.6 Million). Savings can be generated in different categories which depends on healthcare policy. The uncertainty analyses and extreme case scenarios showed the robustness of the results. CONCLUSIONS: Implementation of the OCSS new care strategy for urinary incontinence results in an improvement in the quality of life of community dwelling elderly, a reduction of the costs for payers and affected elderly, and a reduction in time invested by carers. Various realistic policy scenarios even forecast larger health gains and cost-savings in the future. More importantly, the longer the implementation is postponed the larger the savings foregone. The future organisation of healthcare affects the category in which the greatest savings will be generated. PMID- 29454332 TI - Do pregnancies reduce iron overload in HFE hemochromatosis women? results from an observational prospective study. AB - BACKGROUND: HFE hemochromatosis is an inborn error of iron metabolism linked to a defect in the regulation of hepcidin synthesis. This autosomal recessive disease typically manifests later in women than men. Although it is commonly stated that pregnancy is, with menses, one of the factors that offsets iron accumulation in women, no epidemiological study has yet supported this hypothesis. The aim of our study was to evaluate the influence of pregnancy on expression of the predominant HFE p.[Cys282Tyr];[Cys282Tyr] genotype. METHODS: One hundred and forty p.Cys282Tyr homozygous women enrolled in a phlebotomy program between 2004 and 2011 at a blood centre in western Brittany (France) were included in the study. After checking whether the disease expression was delayed in women than in men in our study, the association between pregnancy and iron overload was assessed using multivariable regression analysis. RESULTS: Our study confirms that women with HFE hemochromatosis were diagnosed later than men cared for during the same period (52.6 vs. 47.4 y., P < 0.001). Compared to no pregnancy, having at least one pregnancy was not associated with lower iron markers. In contrast, the amount of iron removed by phlebotomies appeared significantly higher in women who had at least one pregnancy (ebeta = 1.50, P = 0.047). This relationship disappeared after adjustment for confounding factors (ebeta = 1.35, P = 0.088). CONCLUSIONS: Our study shows that pregnancy status has no impact on iron markers level, and is not in favour of pregnancy being a protective factor in progressive iron accumulation. Our results are consistent with recent experimental data suggesting that the difference in disease expression observed between men and women may be explained by other factors such as hormones. PMID- 29454334 TI - Predictors of working beyond retirement in older workers with and without a chronic disease - results from data linkage of Dutch questionnaire and registry data. AB - BACKGROUND: An increasing number of retirees continue to work beyond retirement despite being eligible to retire. As the prevalence of chronic disease increases with age, working beyond retirement may go along with having a chronic disease. Working beyond retirement may be different for retirees with and without chronic disease. We aim to investigate whether demographic, socioeconomic and work characteristics, health and social factors predict working beyond retirement, in workers with and without a chronic disease. METHODS: Employees aged 56-64 years were selected from the Study on Transitions in Employment, Ability and Motivation (N = 1125). Questionnaire data on demographic and work characteristics, health, social factors, and working beyond retirement were linked to registry data from Statistics Netherlands on socioeconomic characteristics. Separate prediction models were built for retirees with and without chronic disease using multivariate logistic regression analyses. RESULTS: Workers without chronic disease were more likely to work beyond retirement compared to workers with chronic disease (27% vs 23%). In retirees with chronic disease, work and health factors predicted working beyond retirement, while in retirees without a chronic disease, work, health and social factors predicted working beyond retirement. In the final model for workers with chronic disease, healthcare work, better physical health, higher body height, lower physical load and no permanent contract were positively predictive of working beyond retirement. In the final model for workers without chronic disease, feeling full of life and being intensively physically active for > = 2 days per week were positively predictive of working beyond retirement; while manual labor, better recovery, and a partner who did not support working until the statutory retirement age, were negatively predictive of working beyond retirement. CONCLUSIONS: Work and health factors independently predicted working beyond retirement in workers with and without chronic disease, whereas social factors only did so among workers without chronic disease. Demographic and socioeconomic characteristics did not independently contribute to prediction of working beyond retirement in any group. As prediction of working beyond retirement was more difficult among workers with a chronic disease, future research is needed in this group. PMID- 29454333 TI - Comparative study of ultrasound-guided paravertebral block versus intravenous tramadol for postoperative pain control in percutaneous nephrolithotomy. AB - BACKGROUND: Percutaneous nephrolithotomy (PCNL) is a minimally invasive surgical procedure for renal calculi, and nephrostomy tubes lead to postoperative pain after PCNL. Regional techniques (e.g., epidural analgesia and peripheral blocks) and opioids are applied for postoperative pain treatment. The aim of this study was to compare effectiveness of ultrasound-guided paravertebral block (PVB) and tramadol on postoperative pain in patients who underwent PCNL. METHOD: Fifty three patients were included in this prospective randomized study. The patients were allocated into two groups: the PVB group (group P, n = 26) and the tramadol group (group T, n = 27). All patients were administered standard general anaesthesia. Ultrasound-guided PVB was performed at the T11- L1 levels using 0.5% bupivacaine for a total dose of 15 mL in group P. Patients in group T were intravenously administered a loading dose of 1 mg/kg tramadol. Patients in both groups were given patient-controlled analgesia. Haemodynamic parameters, visual analogue scale (VAS) scores, side effects, and complications, tramadol consumption and additional analgesic requirements of the patients were recorded after surgery. RESULTS: Haemodynamic parameters were statistically similar between the groups. The VAS in group P were statistically lower than in group T. In the 24-h period after surgery, total PCA tramadol consumption was statistically lower in group P than in group T. The use of supplemental analgesic in group T was higher than in group P. CONCLUSIONS: Ultrasound-guided PVB was found to be an effective analgesia compared to tramadol, and no additional complications were encountered.

PMID- 29454335 TI - Earliella scabrosa-associated postoperative Endophthalmitis after Phacoemulsification with intraocular lens implantation: a case report. AB - BACKGROUND: Postoperative endophthalmitis after cataract surgery is a severe eye infection that can lead to irreversible blindness in the affected eye. The characteristics, treatment and prognosis of this disease vary because of its association with different pathogens. Here, we report what is possibly the first case of endophthalmitis after cataract surgery to be associated with the rare pathogen Earliella scabrosa. CASE PRESENTATION: A 56-year-old man from Hainan Island (China) with a history of phacoemulsification and type II diabetes mellitus underwent intraocular lens (IOL) implantation. He later presented with progressive endophthalmitis in his right eye. IOL explantation with capsular bag removal and a 23G pars plana vitrectomy combined with a silicone oil tamponade was performed. The infection was cleared without recurrence, and the patient's visual acuity improved from light perception to 20/200 in the right eye. An in vitro culture determined that the causative pathogen was Earliella scabrosa, and this result was confirmed by an internal transcribed spacer (ITS) sequence analysis. CONCLUSION: Earliella scabrosa has never been reported as an infectious agent in human eyes, and its clinical significance remains unknown. Here, we report a rare case of Earliella scabrosa-associated endophthalmitis after cataract surgery. The fungal infection presented as an acute attack and was successfully treated with vitrectomy. PMID- 29454336 TI - Change in physical activity level and clinical outcomes in older adults with knee pain: a secondary analysis from a randomised controlled trial. AB - BACKGROUND: Exercise interventions improve clinical outcomes of pain and function in adults with knee pain due to osteoarthritis and higher levels of physical activity are associated with lower severity of pain and higher levels of physical functioning in older adults with knee osteoarthritis in cross-sectional studies. However, to date no studies have investigated if change in physical activity level during exercise interventions can explain clinical outcomes of pain and function. This study aimed to investigate if change in physical activity during exercise interventions is associated with future pain and physical function in older adults with knee pain. METHODS: Secondary longitudinal data analyses of a three armed exercise intervention randomised controlled trial. Participants were adults with knee pain attributed to osteoarthritis, over the age of 45 years old (n = 514) from Primary Care Services in the Midlands and Northwest regions of England. Crude and adjusted associations between absolute change in physical activity from baseline to 3 months (measured by the self-report Physical Activity Scale for the Elderly (PASE)) and i) pain ii) physical function (Western Ontario and McMaster Universities Osteoarthritis Index) and iii) treatment response (OMERACT-OARSI responder criteria) at 3 and 6 months follow-up were investigated using linear and logistic regression. RESULTS: Change in physical activity level was not associated with future pain, function or treatment response outcomes in crude or adjusted models at 3 or 6 months (P > 0.05). A 10 point increase in PASE was not associated with pain beta = - 0.01 (- 0.05, 0.02), physical function beta = - 0.09 (- 0.19, 0.02) or likelihood (odds ratio) of treatment response 1.02 (0.99, 1.04) at 3 months adjusting for sociodemographics, clinical covariates and the trial intervention arm. Findings were similar for 6 month outcome models. CONCLUSIONS: Change in physical activity did not explain future clinical outcomes of pain and function in this study. Other factors may be responsible for clinical improvements following exercise interventions. However, the PASE may not be sufficiently responsive to measure change in physical activity level. We also recommend further investigation into the responsiveness of commonly used physical activity measures. TRIAL REGISTRATION: ( ISRCTN93634563 ). Registered 29th September 2011. PMID- 29454337 TI - The second patient? Family members of cancer patients and their role in end-of life decision making. AB - BACKGROUND: Family members are important companions of severely ill patients with cancer. However, studies about the desirability and difficulties of integrating relatives in the decision-making process are rare in oncology. This qualitative study explores the family role in decisions to limit treatment near the end of life from the professionals' point of view. METHODS: Qualitative in-depth interviews were conducted with oncologists (n = 12) and nurses (n = 6) working at the Department of Hematology/Oncology at the University Hospital in Munich, Germany. The data were analyzed using a descriptive qualitative methodology and discussed from a medical ethics perspective. RESULTS: Four major themes played a central role in the perception of the medical staff in regard to family members. (1) Family impact on patients' treatment preferences. (2) Strong family wish for further treatment. (3) Emotional distress of the family related to the involvement in end-of-life decision-making. (4) Importance of knowing family structures. CONCLUSIONS: The important role of the family members in patients' disease process is recognized by oncologists and oncology nurses. However, this does not seem to lead to an early involvement of the family members. Developing and establishing a systematic assessment of family members' needs and wishes in order to provide a specific-tailored support should become a priority for interdisciplinary clinical research in the near future. PMID- 29454338 TI - "Factors associated with non-small cell lung cancer treatment costs in a Brazilian public hospital". AB - BACKGROUND: The present study estimated the cost of advanced non-small cell lung cancer care for a cohort of 251 patients enrolled in a Brazilian public hospital and identified factors associated with the cost of treating the disease, considering sociodemographic, clinical and behavioral characteristics of patients, service utilization patterns and survival time. METHODS: Estimates were obtained from the survey of direct medical cost per patient from the hospital's perspective. Data was collected from medical records and available hospital information systems. The ordinary least squares (OLS) method with logarithmic transformation of the dependent variable for the analysis of cost predictors was used to take into account the positive skewness of the costs distribution. RESULTS: The average cost of NSCLC was US$ 5647 for patients, with 71% of costs being associated to outpatient care. The main components of cost were daily hospital bed stay (22.6%), radiotherapy (15.5%) and chemotherapy (38.5%). The OLS model reported that, with 5% significance level, patients with higher levels of education, with better physical performance and less advanced disease have higher treatment costs. After controlling for the patient's survival time, only education and service utilization patterns were statistically significant. Individuals who were hospitalized or made use of radiotherapy or chemotherapy had higher costs. The use of these outpatient and hospital services explained most of the treatment cost variation, with a significant increase of the adjusted R2 of 0.111 to 0.449 after incorporation of these variables in the model. The explanatory power of the complete model reached 62%. CONCLUSIONS: Inequities in disease treatment costs were observed, pointing to the need for strategies that reduce lower socioeconomic status and population's hurdles to accessing cancer care services. PMID- 29454339 TI - A structural preview of aquaporin 8 via homology modeling of seven vertebrate isoforms. AB - BACKGROUND: Aquaporins (AQPs) facilitate the passage of small neutral polar molecules across membranes of the cell. In animals there are four distinct AQP subfamilies, whereof AQP8 homologues constitute one of the smallest subfamilies with just one member in man. AQP8 conducts water, ammonia, urea, glycerol and H2O2 through various membranes of animal cells. This passive channel has been connected to a number of phenomena, such as volume change of mitochondria, ammonia neurotoxicity, and mitochondrial dysfunction related to oxidative stress. Currently, there is no experimentally determined structure of an AQP8, hence the structural understanding of this subfamily is limited. The recently solved structure of the plant AQP, AtTIP2;1, which has structural and functional features in common with AQP8s, has opened up for construction of homology models that are likely to be more accurate than previous models. RESULTS: Here we present homology models of seven vertebrate AQP8s. Modeling based on the AtTIP2;1 structure alone resulted in reasonable models except for the pore being blocked by a phenylalanine that is not present in AtTIP2;1. To achieve an open pore, these models were supplemented with models based on the bacterial water specific AQP, EcAqpZ, creating a chimeric monomeric model for each AQP8 isoform. The selectivity filter (also named the aromatic/arginine region), which defines the permeant substrate profile, comprises five amino acid residues in AtTIP2;1, including a histidine coming from loop C. Compared to AtTIP2;1, the selectivity filters of modelled AQP8s only deviates in that they are slightly more narrow and more hydrophobic due to a phenylalanine replacing the histidine from loop C. Interestingly, the models do not exclude the existence of a side pore beneath loop C similar to that described in the structure of AtTIP2;1. CONCLUSIONS: Our models concur that AQP8s are likely to have an AtTIP2;1-like selectivity filter. The detailed description of the expected configuration of residues in the selectivity filters of AQP8s provides an excellent starting point for planning of as well as rationalizing the outcome of mutational studies. Our strategy to compile hybrid models based on several templates may prove useful also for other AQPs for which structural information is limited. PMID- 29454340 TI - Risk perception of blood transfusions - a comparison of patients and allied healthcare professionals. AB - BACKGROUND: Due to an increasing demand in health care services plans to substitute selective physician-conducted medical activities have become attractive. Because administration of a blood transfusion is a highly standardized procedure, it might be evaluated if obtaining a patient's consent for a blood transfusion can be delegated to allied healthcare professionals. Physicians and patients perceive risks of transfusions differently. However, it is unknown how allied healthcare professionals perceive risks of transfusion associated adverse events. METHODS: Patients (n = 506) and allied healthcare professionals (n = 185) of an academic teaching hospital were asked to quantify their concerns about transfusions including five predefined transfusion associated risks and their incidences. RESULTS: Blood transfusions were considered to be generally harmful by 10.9% of patients and 14.6% of caregivers (P = 0.180). Among all surveyed patients, 36.8% were worried about infection transmissions (caregivers: 27.6%; P = 0.024). Compared to 5.4% of caregivers, 13.6% of patients believed infection-transmission was a frequent complication (P = 0.003). Caregivers ranked the risks of receiving an AB0-mismatch transfusion (caregivers: 29.7% vs. PATIENTS: 19.2%, P = 0.003) or a transfusion-associated allergic reaction (caregivers: 17.3% vs. PATIENTS: 11.1%, P = 0.030) significantly higher than patients and were aware of the high incidence of transfusion-associated fever (caregivers: 17.8% vs. PATIENTS: 8.3%, P < 0.001). CONCLUSION: A significant part of interviewees perceived transfusions as a general health hazard. Patients perceived infection-transmissions as the most frequent and greatest transfusion-associated threat while caregivers focused on fatal AB0-mismatch transfusions and allergic reactions. Understanding the patients' main concerns about blood transfusions and considering that these concerns might differ from the view of healthcare professionals might improve the process of shared decision making. PMID- 29454341 TI - Treatment of depression with Chai Hu Shu Gan San: a systematic review and meta analysis of 42 randomized controlled trials. AB - BACKGROUND: Depression is a common mental disorder. Chai Hu Shu Gan San, a traditional Chinese medicine, is used to treat depression empirically. We present a systematic review and meta-analysis of the therapeutic efficacy and safety of Chai Hu Shu Gan San in treating depression. METHODS: Several databases, including PubMed, China National Knowledge Internet, Wanfang, Chongqing VIP, and the Cochrane library, were systematically searched from their date of foundation to January 1, 2017. In this review, wehave included randomized control trials that compared Chai Hu Shu Gan San (or its combination with a regular Western medicine) with a regular Western medicine alone for the treatment of depression. Two investigators independently extracted and analyzed the data using RevMan 5.2.0 software. Mean difference (with a 95% confidence interval) was used as efficacy indices for outcomes. RESULTS: We included 42 studies involving 3234 patients with depression in 15 different types of diseases. Meta analyses showed better effect of Chai Hu Shu Gan San than fluoxetine for pure depression (MD = - 1.59, from - 2.82 to - 0.37, 4 trials, I2 = 26%), for post-stroke depression (MD = - 4.20, from - 6.20 to - 2.19, 7 trials, I2 = 96%), and for postpartum depression (MD = - 4.10, from - 7.48 to - 0.72 7 trials, I2 = 86%). None of the articles reported severe adverse events of oral administration of Chai Hu Shu Gan San. Furthermore, any adverse effects of using Chai Hu Shu Gan San alone were fewer than those of regular Western medicines. CONCLUSIONS: This review found that Chai Hu Shu Gan San has some advantages in treating depression, especially post-stroke depression and post-partum depression. A meticulously designed and conducted randomized control trial is needed for further evaluation. PMID- 29454342 TI - Social support for patients undergoing liver transplantation in a Public University Hospital. AB - BACKGROUND: Several diseases may lead to the need for liver transplantation due to progressive organ damage until the onset of cirrhosis, resulting in changes in interpersonal relationships. Social Support for transplant candidates is an important variable, providing them with psychological and social well-being. This study aims to assess social support in chronic hepatic patients, waiting for liver transplantation. METHODS: A cross-sectional study was conducted with 119 patients, for convenience sampling, from the liver transplant waiting list at a Brazilian University Hospital Outpatients. The information was collected through semistructured questionnaires, in four stages: 1) socioeconomic and demographic information 2) clinical aspects 3) feelings 4) Social Support Network Inventory (SSNI), to Brazilian Portuguese. The statistical analysis was conducted using ANOVA and multivariate linear regression analysis to evaluate the relationship between the scales of social support and the collected co-variables. RESULTS: Average age was 50.2 +/- 11.6, and 87 (73.1%) were men. Patients with alcohol and virus liver disease etiology had the same frequency of 28%. The MELD, without extrapoints, was 16.7 +/- 4.9. Global social support family score was 3.72 +/- 0.39, and Cronbach's alpha = 0.79. The multivariate analysis presented the following associations, age = [- 0.010 (95% CI = - 0.010 - -0.010); P = 0.001], etiology of hepatic disease = [- 0.212 (95% CI = - 0.37 - -0.05); P = 0.009], happiness = [- 0.214(95% CI = - 0.33 - -0.09) P = 0.001) and aggressiveness = [0.172 (95% CI = 0.040-0.030); P = 0.010). CONCLUSIONS: The social support was greater when the patients were younger (18 to 30 years). Patients with alcoholic cirrhosis, regardless of whether or not they were associated with virus, had less social support. As for feelings, the absence of happiness and the presence of aggressiveness showed a negative effect on social support. PMID- 29454343 TI - Systematic development and adjustment of the German version of the Supportive and Palliative Care Indicators Tool (SPICT-DE). AB - BACKGROUND: The Supportive and Palliative Care Indicators tool (SPICT) supports the identification of patients with potential palliative care (PC) needs. An Austrian-German expert group translated SPICT into German (SPICT-DE) in 2014. The aim of this study was the systematic development, refinement, and testing of SPICT-DE for its application in primary care (general practice). METHODS: SPICT DE was developed by a multiprofessional research team according to the TRAPD model: translation, review, adjudication, pretesting and documentation. In a pretest, five general practitioners (GPs) rated four case vignettes of patients with different PC needs. GPs were asked to assess whether each patient might benefit from PC or not (I) based on their subjective appraisal ("usual practice") and (II) by using SPICT-DE. After further refinement, two focus groups with 28 GPs (68% with a further qualification in PC) were conducted to test SPICT-DE. Again, participants rated two selected case vignettes (I) based on their subjective appraisal and (II) by using SPICT-DE. Afterwards, participants reflected the suitability of SPICT-DE for use in their daily practice routine within the German primary care system. Quantitative data were analysed with descriptive statistics and non-parametric tests for small samples. Qualitative data were analysed by conventional content analysis. Focus group discussion was analysed combining formal and conventional content analysis. RESULTS: Compared to the spontaneous rating of the case vignettes based on subjective appraisal, participants in both the pretest and the focus groups considered PC more often as being beneficial for the patients described in the case vignettes when using SPICT-DE. Participants in the focus groups agreed that SPICT-DE includes all relevant indicators necessary for an adequate clinical identification of patients who might benefit from PC. CONCLUSIONS: SPICT-DE supports the identification of patients who might benefit from PC and seems suitable for routine application in general practice in Germany. The systematic development, refinement, and testing of SPICT-DE in this study was successfully completed by using a multiprofessional and participatory approach. PMID- 29454344 TI - Validation of a core patient-reported-outcome measure set for operationalizing success in multimodal pain therapy: useful for depicting long-term success? AB - BACKGROUND: The study aims to validate a previously developed and published combined success criterion for patients after multimodal pain therapy (Donath et al., BMC Health Serv Res 15:272, 2015). The criterion classifies treated patients as successful in the long term on the basis of pain severity, disability through pain, depressiveness, and health-related quality of life. METHODS: Routine longitudinal data of 135 pain patients treated with multimodal pain therapy in 2014-2015 at the Interdisciplinary Pain Center of the University Clinic Erlangen were available at baseline, therapy start, therapy end, and 12 months after treatment. Patients were, on average, 51.0 (SD 11.1) years old and to 63.7% female, two thirds were employed (66.7%). We conducted an analysis of concurrent validity (with: pain severity, disability through pain, depressiveness, mental and physical quality of life), criterion validity (with disability days, self rated success), convergent validity (with stress, anxiety, well-being), and discriminant validity (with chronicity of pain, comorbidity), objectivity, and reliability. Statistically, descriptive and inference statistics, graphical methods and MANOVAs were used. RESULTS: Patients classified as successful had significantly better values on the 5 variables demonstrating concurrent validity (all p < .001), significantly fewer Disability days (M = 15.31 (SD = 23.15) vs. M = 26.75 (SD = 29.15)); t (133) = 2.308; p = .024, less Anxiety (Pillai-Spur: F (3, 131) = 2.972, p = .034), less Stress (Pillai-Spur: F (3, 131) = 9.907, p < .001), and better Well-being (Pillai-Spur: F (3, 131) = 9.594, p < .001) 12 months after treatment than patients classified as not successful. The Spearman correlation between success classification and Chronicity stage was .094 (p = .280). CONCLUSION: We demonstrated the validity of the combined success criterion with long-term data in addition to confirming the reliability and objectivity of the criterion. Future research might consider identifying predictors of success in multi-modal pain therapy. PMID- 29454345 TI - Associations of total and type-specific physical activity with mortality in chronic obstructive pulmonary disease: a population-based cohort study. AB - BACKGROUND: Regular physical activity is recommended for all people with chronic obstructive pulmonary disease (COPD), but the dose of physical activity required to gain mortality benefit in this population is not yet known. This aim of this study was to examine the associations of total and type-specific physical activity with mortality risk in people with COPD. METHODS: People with COPD aged >=40 years were identified from the 1997 Health Survey for England and the 1998 and 2003 Scottish Health Survey cohorts. Self-reported total physical activity, moderate-vigorous intensity physical activity (MVPA), walking, domestic physical activity, and sport/exercise were assessed at baseline. Cox proportional hazards models were used to examine the associations between physical activity and mortality risk. RESULTS: Two thousand three hundred ninety-eight participants with COPD were included in the analysis and followed up for a mean 8.5 (SD 3.9) years. For both total physical activity and MVPA, we observed dose-response associations with all-cause and cardiovascular disease (CVD) mortality risk, and with respiratory mortality risk to a lesser extent. Compared to those who reported no physical activity, participants who met the physical activity guidelines demonstrated the greatest reductions in all-cause (HR 0.56, 95% CI 0.45-0.69), CVD (HR 0.48, 95% CI 0.32-0.71) and respiratory mortality risk (HR 0.40, 95% CI 0.24-0.67). Participants who reported a level of physical activity of at least half the dosage recommended by the guidelines also had a reduced risk of all-cause (HR 0.75, 95% CI 0.56-1.00) and CVD mortality (HR 0.48, 95% CI 0.26 0.88). Dose-response associations with mortality risk were demonstrated for walking and sport/exercise, but not domestic physical activity. CONCLUSIONS: We found a dose-response association between physical activity and all-cause and CVD mortality risk in people with COPD, with protective effects appearing at levels considerably lower than the general physical activity recommendations. People with COPD may benefit from engagement in low levels of physical activity, particularly walking and structured exercise. PMID- 29454346 TI - Agrobacterium-mediated and electroporation-mediated transformation of Chlamydomonas reinhardtii: a comparative study. AB - BACKGROUND: Chlamydomonas reinhardtii is an unicellular green alga used for functional genomics studies and heterologous protein expression. A major hindrance in these studies is the low level and instability of expression of nuclear transgenes, due to their rearrangement and/or silencing over time. RESULTS: We constructed dedicated vectors for Agrobacterium-mediated transformation carrying, within the T-DNA borders, the Paromomycin (Paro) selectable marker and an expression cassette containing the Luciferase (Luc) reporter gene. These vectors and newly developed co-cultivation methods were used to compare the efficiency, stability and insertion sites of Agrobacterium- versus electroporation-mediated transformation. The influence of different transformation methods, of the cell wall, of the virulence of different Agrobacterium strains, and of transgene orientation with respect to T-DNA borders were assessed. False positive transformants were more frequent in Agrobacterium mediated transformation compared to electroporation, compensating for the slightly lower proportion of silenced transformants observed in Agrobacterium mediated transformation than in electroporation. The proportion of silenced transformants remained stable after 20 cycles of subculture in selective medium. Next generation sequencing confirmed the nuclear insertion points, which occurred in exons or untraslated regions (UTRs) for 10 out of 10 Agrobacterium-mediated and 9 out of 13 of electroporation-mediated insertions. Electroporation also resulted in higher numbers of insertions at multiple loci. CONCLUSIONS: Due to its labor-intensive nature, Agrobacterium transformation of Chlamydomonas does not present significant advantages over electroporation, with the possible exception of its use in insertional mutagenesis, due to the higher proportion of within-gene, single-locus insertions. Our data indirectly support the hypothesis that rearrangement of transforming DNA occurs in the Chlamydomonas cell, rather than in the extracellular space as previously proposed.

AB - BACKGROUND: Double-checking medications is a widely used strategy to enhance safe medication administration in oncology, but there is little evidence to support its effectiveness. The proliferated use of double-checking may be explained by positive attitudes towards checking among nurses. This study investigated oncology nurses' beliefs towards double-checking medication, its relation to beliefs about safety and the influence of nurses' level of experience and proximity to clinical care. METHODS: This was a survey of all oncology nurses in three Swiss hospitals. The questionnaire contained 41 items on 6 domains. Responses were recorded using a 7-point Likert scale. Multiple regression analysis was used to identify factors linked to strong beliefs in the effectiveness of double-checking. RESULTS: Overall, 274 (70%) out of 389 nurses responded (91% female, mean age 37 (standard deviation = 10)). Nurses reported very strong beliefs in the effectiveness and utility of double-checking. They were also confident about their own performance in double-checking. Nurses widely believed that double checking produced safety (e.g., 86% believed errors of individuals could be intercepted with double-checks). In contrast, some limitations of double-checking were also recognized, e.g., 33% of nurses reported that double checking caused frequent interruptions and 28% reported that double checking was done superficially in their unit. Regression analysis revealed that beliefs in effectiveness of double-checking were mainly associated with beliefs in safety production (p < 0.001). Nurses with experience in barcode scanning held less strong beliefs in effectiveness of double-checking (p = 0.006). In contrast to our expectations, there were no differences in beliefs between any professional sub-groups. CONCLUSION: The widespread and strong believe in the effectiveness of double-checking is linked to beliefs about safety production and co-exists with acknowledgement of the major disadvantages of double-checking by humans. These results are important factors to consider when any existing procedures are adapted or new checking procedures are implemented.

AB - BACKGROUND: Genome sequencing revealed that Streptomyces sp. can dedicate up to ~ 10% of their genomes for the biosynthesis of bioactive secondary metabolites. However, the majority of these biosynthetic gene clusters are only weakly expressed or not at all. Indeed, the biosynthesis of natural products is highly regulated through integrating multiple nutritional and environmental signals perceived by pleiotropic and pathway-specific transcriptional regulators. Although pathway-specific refactoring has been a proved, productive approach for the activation of individual gene clusters, the construction of a global super host strain by targeting pleiotropic-specific genes for the expression of multiple diverse gene clusters is an attractive approach. RESULTS: Streptomyces albus J1074 is a gifted heterologous host. To further improve its secondary metabolite expression capability, we rationally engineered the host by targeting genes affecting NADPH availability, precursor flux, cell growth and biosynthetic gene transcriptional activation. These studies led to the activation of the native paulomycin pathway in engineered S. albus strains and importantly the upregulated expression of the heterologous actinorhodin gene cluster. CONCLUSIONS: Rational engineering of Streptomyces albus J1074 yielded a series of mutants with improved capabilities for native and heterologous expression of secondary metabolite gene clusters. PMID- 29454349 TI - SGEF is a potential prognostic and therapeutic target for lung adenocarcinoma. AB - BACKGROUND: SH3-containing guanine nucleotide exchange factor (SGEF), a RhoG specific guanine nucleotide exchange factor (GEF), was consider as a key signal that determines cancer cell invasion. Although SGEF has been considered to highly express in glioma and prostate cancer. However, it is not well illustrated in LAC. METHODS: In this experiment, expression of SGEF was detected in 92 LAC and corresponding normal tissue samples by immunohistochemistry. In addition, we evaluated the invasion and migration of lung adenocarcinoma cells by the gain and loss of SGEF expression. Furthermore, RhoG activity was measured by GST pull-down assay. RESULTS: SGEF is highly expressed in LAC tissues than in normal lung tissues and was associated with the TNM stage. Lung adenocarcinoma patients with low SGEF subgroup had longer overall survival compared to those with high expression. Furthermore, univariate analysis showed that SGEF expression was an independent prognostic factor for overall survival in lung adenocarcinoma. Silencing of SGEF effectively suppressed the invasion and migration of human lung adenocarcinoma cells in vitro by inhibiting RhoG activity, and over-expression of SGEF could reverse this phenomena. CONCLUSION: SGEF is a novel prognostic target in human lung adenocarcinoma. PMID- 29454350 TI - Application of four-dimension criteria to assess rigour of qualitative research in emergency medicine. AB - BACKGROUND: The main objective of this methodological manuscript was to illustrate the role of using qualitative research in emergency settings. We outline rigorous criteria applied to a qualitative study assessing perceptions and experiences of staff working in Australian emergency departments. METHODS: We used an integrated mixed-methodology framework to identify different perspectives and experiences of emergency department staff during the implementation of a time target government policy. The qualitative study comprised interviews from 119 participants across 16 hospitals. The interviews were conducted in 2015-2016 and the data were managed using NVivo version 11. We conducted the analysis in three stages, namely: conceptual framework, comparison and contrast and hypothesis development. We concluded with the implementation of the four-dimension criteria (credibility, dependability, confirmability and transferability) to assess the robustness of the study, RESULTS: We adapted four-dimension criteria to assess the rigour of a large-scale qualitative research in the emergency department context. The criteria comprised strategies such as building the research team; preparing data collection guidelines; defining and obtaining adequate participation; reaching data saturation and ensuring high levels of consistency and inter-coder agreement. CONCLUSION: Based on the findings, the proposed framework satisfied the four-dimension criteria and generated potential qualitative research applications to emergency medicine research. We have added a methodological contribution to the ongoing debate about rigour in qualitative research which we hope will guide future studies in this topic in emergency care research. It also provided recommendations for conducting future mixed-methods studies. Future papers on this series will use the results from qualitative data and the empirical findings from longitudinal data linkage to further identify factors associated with ED performance; they will be reported separately. PMID- 29454351 TI - Disparate compensation policies for research related injury in an era of multinational trials: a case study of Brazil, Russia, India, China and South Africa. AB - BACKGROUND: Compensation for research related injuries is a subject that is increasingly gaining traction in developing countries which are burgeoning destinations of multi center research. However, the existence of disparate compensation rules violates the ethical principle of fairness. The current paper presents a comparison of the policies of Brazil, Russia, India, China and South Africa (BRICS). METHODS: A systematic search of good clinical practice guidelines was conducted employing search strategies modeled in line with the recommendations of ADPTE Collaboration (2007). The search focused on three main areas namely bibliographic data bases, clinical practice guidelines data bases and a restricted internet search. A manual search of references cited in relevant guideline documents was also conducted. The search terms, Medical Subject Headings (MeSH) and key words were developed for a PubMed platform and then adapted for all other data bases. The search terms were kept constant for each country with the only difference being the country name. The documents so obtained were subjected to systematic content analysis. RESULTS: The study revealed that there is vast panoply of regulations which exist on a continuum. On one extreme is India with comprehensive regulations that are codified into law, and on the other end there is China which does not have specific laws regulating research related injuries. There are a number of differences and similarities such as mandatory insurance requirements, existence of no fault compensation, compensable injuries and the role of research ethics committees. CONCLUSIONS: It is imperative to enact legislations that protect participants without stifling the research enterprise. There is need for consistency and ideally harmonization of such regulations at a global level. A model policy on compensation for research related injuries should borrow from the best aspects of the different country policies and should be informed by the cardinal ethics principles of autonomy, justice and beneficence. PMID- 29454352 TI - Lower pole approach in retroperitoneal laparoscopic radical nephrectomy: a new approach for the management of renal vascular pedicle. AB - BACKGROUND: The objective of this study was to examine the effectiveness and safety of lower pole (LP) approach in retroperitoneal laparoscopic radical nephrectomy (LRN). METHODS: One hundred thirty-two renal cancer patients were scheduled for selective retroperitoneal LRN. The surgery parameters and outcomes were compared. Out of 132 patients, 78 (59.1%) patients underwent LRN via LP approach, while 54 (40.9%) patients underwent LRN via lateroposterior space (LPS) approach. RESULTS: Compared to LPS group, the LP group had a higher body mass index (27.0 +/- 1.7 kg/m2 vs. 24.5 +/- 1.8 kg/m2, P < 0.0001) and a larger tumor size (6.9 +/- 3.5 cm vs. 4.1 +/- 3.3 cm, P < 0.0001). The LP approach reduced the volumes of blood loss and transfusion significantly (135.3 +/- 17.2 mL vs. 219.6 +/- 30.9 mL, P < 0.0001; 55.6 +/- 28.3 vs. 141.1 +/- 50.4 mL, P < 0.0001) as compared to the LPS approach. The LP approach also decreased the risk of conversion to open procedure (1.3 vs. 7.4%, P < 0.05). CONCLUSIONS: The LP approach is an effective and safe alternative to the LPS approach for retroperitoneal LRN and might be more suitable for patients with obesity, large tumors, tumors located at the medial part of the kidney, or renal pedicular adhesion. PMID- 29454354 TI - Cerebrospinal fluid level of Nogo receptor 1 antagonist lateral olfactory tract usher substance (LOTUS) correlates inversely with the extent of neuroinflammation. AB - BACKGROUND: Although inflammation in the central nervous system is responsible for multiple neurological diseases, the lack of appropriate biomarkers makes it difficult to evaluate inflammatory activities in these diseases. Therefore, a new biomarker reflecting neuroinflammation is required for accurate diagnosis, appropriate therapy, and comprehension of pathogenesis of these neurological disorders. We previously reported that the cerebrospinal fluid (CSF) concentration of lateral olfactory tract usher substance (LOTUS), which promotes axonal growth as a Nogo receptor 1 antagonist, negatively correlates with disease activity in multiple sclerosis, suggesting that variation in LOTUS reflects the inflammatory activities and is a useful biomarker to evaluate the disease activity. To extend this observation, we analyzed the variation of LOTUS in the CSF of patients with bacterial and viral meningitis, which are the most common neuroinflammatory diseases. METHODS: CSF samples were retrospectively obtained from patients with meningitis (n = 40), who were followed up by CSF study at least twice, and from healthy controls (n = 27). Patients were divided into bacterial (n = 14) and viral meningitis (n = 18) after exclusion of eight patients according to the criteria of this study. LOTUS concentrations, total protein levels, and CSF cell counts in the acute and recovery phases were analyzed chronologically. We also used lipopolysaccharide-injected mice as a model of neuroinflammation to evaluate LOTUS mRNA and protein expression in the brain. RESULTS: Regardless of whether meningitis was viral or bacterial, LOTUS concentrations in the CSF of patients in acute phase were lower than those of healthy controls. As the patients recovered from meningitis, LOTUS levels in the CSF returned to the normal range. Lipopolysaccharide-injected mice also exhibited reduced LOTUS mRNA and protein expression in the brain. CONCLUSIONS: CSF levels of LOTUS correlated inversely with disease activity in both bacterial and viral meningitis, as well as in multiple sclerosis, because neuroinflammation downregulated LOTUS expression. Our data strongly suggest that variation of CSF LOTUS is associated with neuroinflammation and is useful as a biomarker for a broader range of neuroinflammatory diseases. PMID- 29454355 TI - Temporal changes of fine root overyielding and foraging strategies in planted monoculture and mixed forests. AB - BACKGROUND: Mixed forests are believed to enhance ecosystem functioning and sustainability due to complementary resource use, environmental benefits and improved soil properties. The facilitation between different species may induce overyielding. Meanwhile, the species-specific fine root foraging strategies and tradeoffs would determine the structure and dynamics of plant communities. Here the aim was to investigate the admixing effects of fine-root biomass, vertical distribution and morphology in Pinus massoniana-Cinnamomum camphora mixed plantations and corresponding monocultures at 10-, 24- and 45-year old stands. RESULTS: The fine root biomass in the Pinus-Cinnamomum mixed forest exerted a certain degree of overyielding effect. These positive admixing effects, however, did not enhance with forest stand development. The overall relative yield total ranged from 1.83 and 1.51 to 1.33 in 10-, 24- and 45-year-old stand, respectively. The overyielding was mainly attributed to the over-performance of late successional species, Cinnamomum, in mixed stands. The vertical fine root biomass distribution model showed fine roots of pioneer species, Pinus, shifted to the superficial layer when mixed with Cinnamomum. Furthermore, the specific root length (SRL) of Pinus was significantly higher in Pinus-Cinnamomum mixed stands than that in monocultures, and the magnitude of differences increased over time. However, the vertical fine-root distribution and SRL for Cinnamomum did not show significant differences between monoculture and mixtures. CONCLUSIONS: Our results indicated that the magnitude of fine root overyielding in mixed forests showed a high degree of consistency with the total amount of fine root biomass itself, suggesting the overyielding effects in mixed forests were correlated with the degree of belowground interaction and competition degree involved. The late successional species, Cinnamomum, invested more carbon to belowground by increasing the fine root biomass in mixtures. While the pioneer species, Pinus, adapted to the presence of the species Cinnamomum by modification of vertical distribution and root morphological plasticity in the mixtures. These species specific fine root foraging strategies might imply the differences of forest growth strategies of co-occurring species and contribute to the success and failure of particular species during the succession over time. PMID- 29454353 TI - Genetics of the human Y chromosome and its association with male infertility. AB - The human Y chromosome harbors genes that are responsible for testis development and also for initiation and maintenance of spermatogenesis in adulthood. The long arm of the Y chromosome (Yq) contains many ampliconic and palindromic sequences making it predisposed to self-recombination during spermatogenesis and hence susceptible to intra-chromosomal deletions. Such deletions lead to copy number variation in genes of the Y chromosome resulting in male infertility. Three common Yq deletions that recur in infertile males are termed as AZF (Azoospermia Factor) microdeletions viz. AZFa, AZFb and AZFc. As estimated from data of nearly 40,000 Y chromosomes, the global prevalence of Yq microdeletions is 7.5% in infertile males; however the European infertile men are less susceptible to Yq microdeletions, the highest prevalence is in Americans and East Asian infertile men. In addition, partial deletions of the AZFc locus have been associated with infertility but the effect seems to be ethnicity dependent. Analysis of > 17,000 Y chromosomes from fertile and infertile men has revealed an association of gr/gr deletion with male infertility in Caucasians and Mongolian men, while the b2/b3 deletion is associated with male infertility in African and Dravidian men. Clinically, the screening for Yq microdeletions would aid the clinician in determining the cause of male infertility and decide a rational management strategy for the patient. As these deletions are transmitted to 100% of male offspring born through assisted reproduction, testing of Yq deletions will allow the couples to make an informed choice regarding the perpetuation of male infertility in future generations. With the emerging data on association of Yq deletions with testicular cancers and neuropsychiatric conditions long term follow-up data is urgently needed for infertile men harboring Yq deletions. If found so, the information will change the current the perspective of androgenetics from infertility and might have broad implication in men health. PMID- 29454356 TI - Multiple forms of discrimination and relationships with health and wellbeing: findings from national cross-sectional surveys in Aotearoa/New Zealand. AB - BACKGROUND: The complex ways in which experiences of discrimination are patterned in society, including the exposure of communities to multiple overlapping forms of discrimination within social systems of oppression, is increasingly recognised in the health sciences. However, research examining the impacts on health and contribution to racial/ethnic health inequities remains limited. This study aims to contribute to the field by exploring the prevalence and patterning of experience of multiple forms of discrimination in Aotearoa/New Zealand, and associations with health and wellbeing. METHODS: The study's conceptual approach is informed by Kaupapa Maori theory, Ecosocial theory, Critical Race Theory and intersectionality. Data are from the 2008, 2010 and 2012 General Social Surveys (GSS), biennial nationally-representative surveys in Aotearoa/New Zealand. We examined patterning of forms of discrimination in the last 12 months and frequency of experiencing multiple forms of discrimination. We also looked at associations between experience of multiple discrimination and self-rated health, mental health (using SF12), and life satisfaction using logistic regression. We used random effects meta-analysis to produce pooled estimates drawing from all three survey instances. RESULTS: Maori, and people from Pacific and Asian ethnic groups, reported much higher prevalence of racial discrimination, were more likely to have any experience of discrimination, and were also more likely to experience multiple forms of discrimination, in the last year relative to respondents in the European/Other category. Discrimination was associated with poorer self-rated health, poorer mental health, and greater life dissatisfaction in unadjusted and adjusted estimates. Negative health impacts increased as the number of forms of discrimination experienced increased. CONCLUSIONS: Discrimination impacts negatively on the health of indigenous peoples and those from minoritised ethnic groups in Aotearoa/New Zealand through higher exposure to racial discrimination, other forms of discrimination, and a greater likelihood of experiencing multiple forms of discrimination. This supports the need for research and interventions that more fully account for the multiple and interlocking ways in which discrimination impacts on health in racialised social hierarchies to maintain systems of privilege and oppression. PMID- 29454357 TI - Border analysis for spatial clusters. AB - BACKGROUND: The spatial scan statistic is widely used by public health professionals in the detection of spatial clusters in inhomogeneous point process. The most popular version of the spatial scan statistic uses a circular shaped scanning window. Several other variants, using other parametric or non parametric shapes, are also available. However, none of them offer information about the uncertainty on the borders of the detected clusters. METHOD: We propose a new method to evaluate uncertainty on the boundaries of spatial clusters identified through the spatial scan statistic for Poisson data. For each spatial data location i, a function F(i) is calculated. While not a probability, this function takes values in the [0, 1] interval, with a higher value indicating more evidence that the location belongs to the true cluster. RESULTS: Through a set of simulation studies, we show that the F function provides a way to define, measure and visualize the certainty or uncertainty of each specific location belonging to the true cluster. The method can be applied whether there are one or multiple detected clusters on the map. We illustrate the new method on a data set concerning Chagas disease in Minas Gerais, Brazil. CONCLUSIONS: The higher the intensity given to an area, the higher the plausibility of that particular area to belong to the true cluster in case it exists. This way, the F function provides information from which the public health practitioner can perform a border analysis of the detected spatial scan statistic clusters. We have implemented and illustrated the border analysis F function in the context of the circular spatial scan statistic for spatially aggregated Poisson data. The definition is clearly independent of both the shape of the scanning window and the probability model under which the data is generated. To make the new method widely available to users, it has been implemented in the freely available SaTScan[Formula: see text] software www.satscan.org . PMID- 29454358 TI - Surgical resection for clinical stage I high-grade neuroendocrine carcinoma of the lung. AB - BACKGROUND: There are few reports about the factor influencing the prognosis of high-grade neuroendocrine carcinoma. In this study, we evaluated surgical outcome of clinical stage I high-grade neuroendocrine carcinoma. METHODS: Patients who underwent curative surgery for high-grade neuroendocrine tumors of the lung in clinical stage I were included in this study. We retrospectively analyzed 27 consecutive patients. The aim of this study was to clarify the clinical course of the disease after surgery and what factors influence the prognosis. RESULTS: Twenty-two patients have small cell carcinoma, and 5 patients have large cell neuroendocrine carcinoma. Patients who could undergo surgery within 60 days after the first visit (p < 0.01) and undergo lobectomy (p < 0.01) and whose pro-gastrin releasing peptide ? 72 pg/ml (p = 0.04) performed good prognosis after surgery. In multivariate analysis, surgery within 60 days and operative procedure were independent factors associated with OS. CONCLUSION: Surgical resection for clinical stage I high-grade neuroendocrine carcinoma of the lung should be performed as early as possible, and better outcome can be obtained with lobectomy than partial resection. PMID- 29454359 TI - Change in practice: a qualitative exploration of midwives' and doctors' views about the introduction of STan monitoring in an Australian hospital. AB - BACKGROUND: The present study examines the introduction of an innovation in intrapartum foetal monitoring practice in Australia. ST-Analysis (STan) is a technology that adds information to conventional fetal monitoring (cardiotocography) during labour, with the aim of reducing unnecessary obstetric intervention. Adoption of this technology has been controversial amongst obstetricians and midwives, particularly as its use necessitates a more invasive means of monitoring (a scalp clip), compared to external monitoring from cardiotocography alone. If adoption of this technology is going to be successful, then understanding staff opinions about the implementation of STan in an Australian setting is an important issue for maternity care providers and policy makers. METHODS: Using a maximum variation purposive sampling method, 18 interviews were conducted with 10 midwives and 8 doctors from the Women's and Children's Hospital, South Australia to explore views about the introduction of the new technology. The data were analysed using Framework Analysis. RESULTS: Midwives and doctors indicated four important areas of consideration when introducing STan: 1) philosophy of care; 2) the implementation process including training and education; 3) the existence of research evidence; and 4) attitudes towards the new technology. Views were expressed about the management of change process, the fit of the new technology within the current models of care, the need for ongoing training and the importance of having local evidence. CONCLUSIONS: These findings, coupled with the general literature about introducing innovation and change, can be used by other centres looking to introduce STan technology. PMID- 29454360 TI - Reliability of length measurements collected by community nurses and health volunteers in rural growth monitoring and promotion services. AB - BACKGROUND: Length measurements are important in growth, monitoring and promotion (GMP) for the surveillance of a child's weight-for-length and length-for-age. These two indices provide an indication of a child's risk of becoming wasted or stunted, and are more informative about a child's growth than the widely used weight-for-age index (underweight). Although the introduction of length measurements in GMP is recommended by the World Health Organization, concerns about the reliability of length measurements collected in rural outreach settings have been expressed by stakeholders. Our aim was to describe the reliability and challenges associated with community health personnel measuring length for rural outreach GMP activities. METHODS: Two reliability studies (A and B), using 10 children less than 24 months each, were conducted in the GMP services of a rural district in Ghana. Fifteen nurses and 15 health volunteers (HV) with no prior experience in length measurements were trained. Intra- and inter-observer technical error of measurement (TEM), average bias from expert anthropometrist, and coefficient of reliability (R) of length measurements were assessed and compared across sessions. Observations and interviews were used to understand the ability and experiences of health personnel with measuring length at outreach GMP. RESULTS: Inter-observer TEM was larger than intra-observer TEM for both nurses and HV at both sessions and was unacceptably (compared to error standards) high in both groups at both time points. Average biases from expert's measurements were within acceptable limits, however, both groups tended to underestimate length measurements. The R for lengths collected by nurses (92.3%) was higher at session B compared to that of HV (87.5%). Length measurements taken by nurses and HV, and those taken by an experienced anthropometrist at GMP sessions were of moderate agreement (kappa = 0.53, p < 0.0001). CONCLUSIONS: The reliability of length measurements improved after two refresher trainings for nurses but not for HV. In addition, length measurements taken during GMP sessions may be susceptible to errors due to overburdened health personnel and crowded GMP clinics. There is need for both pre- and in-service training of nurses and HV on length measurements and procedures to improve reliability of length measurements. PMID- 29454361 TI - Wnt-signaling enhances neural crest migration of melanoma cells and induces an invasive phenotype. AB - BACKGROUND: During embryonic development Wnt family members and bone morphogenetic proteins (BMPs) cooperatively induce epithelial-mesenchymal transition (EMT) in the neural crest. Wnt and BMPs are reactivated during malignant transformation in melanoma. We previously demonstrated that the BMP antagonist noggin blocked the EMT phenotype of melanoma cells in the neural crest and malignant invasion of melanoma cells in the chick embryo; vice-versa, malignant invasion was induced in human melanocytes in vivo by pre-treatment with BMP-2. RESULTS: Although there are conflicting results in the literature about the role of beta-catenin for invasion of melanoma cells, we found Wnt/beta catenin signaling to be analogously important for the EMT-like phenotype of human metastatic melanoma cells in the neural crest and during invasion: beta-catenin was frequently expressed at the invasive front of human primary melanomas and Wnt3a expression was inversely correlated with survival of melanoma patients. Accordingly, cytoplasmic beta-catenin levels were increased during invasion of melanoma cells in the rhombencephalon of the chick embryo. Fibroblast derived Wnt3a reduced melanoma cell adhesion and enhanced migration, while the beta catenin inhibitor PKF115-584 increased adhesion and reduced migration in vitro and in the chick embryonic neural crest environment in vivo. Similarly, knockdown of beta-catenin impaired intradermal melanoma cell invasion and PKF115-584 efficiently reduced liver metastasis in a chick chorioallantoic membrane model. Our observations were accompanied by specific alterations in gene expression which are linked to overall survival of melanoma patients. CONCLUSION: We present a novel role for Wnt-signaling in neural crest like melanoma cell invasion and metastasis, stressing the crucial role of embryonic EMT-inducing neural crest signaling for the spreading of malignant melanoma. PMID- 29454362 TI - Self-assembly/disassembly hysteresis of nanoparticles composed of marginally soluble, short elastin-like polypeptides. AB - BACKGROUND: Elastin-like polypeptides (ELPs) are a fascinating biomaterial that has undergone copious development for a variety of therapeutic applications including as a nanoscale drug delivery vehicle. A comprehensive understanding of ELP self-assembly is lacking and this knowledge gap impedes the advancement of ELP-based biomaterials into the clinical realm. The systematic examination of leucine-containing ELPs endeavors to expand existing knowledge about fundamental assembly-disassembly behaviours. RESULTS: It was observed that these marginally soluble, short ELPs tend to behave consistently with previous observations related to assembly-related ELP phase transitions but deviated in their disassembly. It was found that chain length, concentration and overall sequence hydrophobicity may influence the irreversible formation of sub-micron particles as well as the formation of multi-micron scale, colloidally unstable aggregates. Amino acid composition affected surface charge and packing density of the particles. Particle stability upon dilution was found to vary depending upon chain length and hydrophobicity, with particles composed of longer and/or more hydrophobic ELPs being more resistant to disassembly upon isothermal dilution. CONCLUSIONS: Taken together, these results suggest marginally soluble ELPs may self-assemble but not disassemble as expected and that parameters including particle size, zeta potential and dilution resistance would benefit from widespread systematic evaluations. This information has the potential to reveal novel preparation methods capable of expanding the utility of all existing ELP based biomaterials. PMID- 29454364 TI - Cyclosporine A does not prevent second-eye involvement in Leber's hereditary optic neuropathy. AB - BACKRGROUND: Evaluation of the efficacy of oral cyclosporine A as a prophylactic agent in preventing second-eye involvement in Leber's hereditary optic neuropathy (LHON) in a prospective, open-label, non-randomized, multicenter pilot study. Only LHON patients aged 18 years or more, with confirmed primary mitochondrial DNA mutations and strictly unilateral optic neuropathy occurring within 6 months prior to enrolment, were included in the study. All these patients, receiving treatment with oral cyclosporine (Neoral(r), Novartis) at 2.5 mg/kg/day, were examined at three-month intervals for a year. The primary endpoint was the best corrected visual acuity in the unaffected eye; the secondary endpoints were the best corrected visual acuity in the first eye affected, the mean visual field defect on automated perimetry, the thickness of the perifoveal retinal ganglion cell inner plexiform layer, and the thickness of the peripapillary retinal nerve fiber layer in both eyes. RESULTS: Among the 24 patients referred to our institution with genetically confirmed LHON, between July 2011 and April 2014, only five patients, four males and one female, fulfilled the inclusion criteria. Age at enrolment ranged from 19 to 42 years (mean: 27.2 years; median: 26 years), four patients harbored the m.11778G > A pathogenic variant, and one the m.14484 T > C pathogenic variant. The time-interval between the onset of symptoms and inclusion in the study ranged from 7 to 17 weeks (mean: 11.8 weeks; median: 9 weeks). Despite treatment with oral cyclosporine A, all patients eventually experienced bilateral eye involvement, occurring within 11-65 weeks after the initiation of treatment. Over the study time period, the average best corrected visual acuity worsened in the first eye affected; by the end of the study, both eyes were equally affected. CONCLUSIONS: Oral cyclosporine, at 2.5 mg/kg/day, did not prevent second-eye involvement in patients with strictly unilateral Leber's hereditary optic neuropathy. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02176733 . Registrated June 25, 2014. PMID- 29454365 TI - Qualitative evaluation of the Saleema campaign to eliminate female genital mutilation and cutting in Sudan. AB - BACKGROUND: Female genital mutilation and cutting (FGM/C, herein FGM) is a widespread and harmful practice. The Government developed a national campaign in Sudan, called Saleema, to change social norms discouraging FGM. Saleema translates to being "whole", healthy in body and mind, unharmed, intact, pristine, and untouched, in a God-given condition. An interim evaluation was conducted using focus groups among Sudanese adults. The primary aim was to explore perceptions of the Saleema poster exemplars and to assess if the desired themes were being communicated. Secondary aims were to understand more about participants' information sources, values, and suggestions for the campaign broadly. METHODS: The Saleema campaign evaluation included four focus groups from each of the 18 states in Sudan (72 total). Participants were presented with three poster stimuli from the Saleema campaign and asked about the content and their reactions. Themes were coded inductively by concepts that arose through content in the transcripts. Codes were also reviewed in conjunction with themes from the broader Saleema evaluation framework. RESULTS: Participants reported the most common source of information or admiration was from local leaders who are responsive to a community, media-based outlets, and discussions among community members. Participants held high value for education, community solidarity, and/or religious devotion. Participants had positive opinions of Saleema and responded positively to the branding elements in the posters and the campaign as a whole. The most common suggestion was continued awareness. Advocacy, training, and posters were suggested to highlight the harms of FGM through leaders or in community settings. Individuals suggested that these activities target older women and individuals in rural villages. There was also a burgeoning theme of targeting youth for support of the campaign. DISCUSSION: The results of this focus group analysis demonstrate support for future Saleema campaign efforts promoting awareness and community engagement. The campaign could capitalize on partnerships with young people and those who are respected in the community (e.g., religious leaders) or continue promoting common values aligning with the support of education and community solidarity. Continuing campaign efforts have promise to decrease the harms of FGM in Sudan. PMID- 29454363 TI - Identification of wild-caught phlebotomine sand flies from Crete and Cyprus using DNA barcoding. AB - BACKGROUND: Phlebotomine sand flies (Diptera: Psychodidae) are vectors of Leishmania spp., protozoan parasites responsible for a group of neglected diseases called leishmaniases. Two sand fly genera, Phlebotomus and Sergentomyia, contain species that are present in the Mediterranean islands of Crete and Cyprus where the visceral (VL), cutaneous (CL) and canine (CanLei) leishmaniases are a public health concern. The risk of transmission of different Leishmania species can be studied in an area by monitoring their vectors. Sand fly species are traditionally identified using morphological characteristics but minute differences between individuals or populations could be overlooked leading to wrong epidemiological predictions. Molecular identification of these important vectors has become, therefore, an essential tool for research tasks concerning their geographical distribution which directly relates to leishmaniasis control efforts. DNA barcoding is a widely used molecular identification method for cataloguing animal species by sequencing a fragment of the mitochondrial gene encoding cytochrome oxidase I. RESULTS: DNA barcoding was used to identify individuals of five sand fly species (Phlebotomus papatasi, P. similis, P. killicki, Sergentomyia minuta, S. dentata) circulating in the islands of Crete and Cyprus during the years 2011-2014. Phlebotomus papatasi is a known vector of zoonotic CL in the Middle East and it is found in both islands. Phlebotomus similis is the suspected vector of Leishmania tropica in Greece causing anthroponotic CL. Phlebotomus killicki was collected in Cyprus for the first time. Sergentomyia minuta, found to present intraspecific diversity, is discussed for its potential as a Leishmania vector. Molecular identification was consistent with the morphological identification. It successfully identified males and females, which is difficult when using only morphological characters. A phylogenetic tree was constructed based on the barcodes acquired, representing their genetic relationships along with other species from the area studied. All individuals identified were clustered according to their species and subgenus. CONCLUSIONS: Molecular identification of sand flies via DNA barcoding can accurately identify these medically important insects assisting traditional morphological tools, thus helping to assess their implication in Leishmania transmission. PMID- 29454366 TI - Occurrence of Blastocystis sp. and Pentatrichomonas hominis in sheep and goats in China. AB - BACKGROUND: Global data regarding the molecular epidemiology of Blastocystis sp. and Pentatrichomonas hominis in sheep and goats are sparse. China has one of the largest sheep and goat populations in the world. In this study we investigated the occurrence of Blastocystis sp. and P. hominis in domestic sheep and goats in China, and analyzed the genetic characterization of these two parasite species. METHODS: In total, we collected fresh fecal samples from 832 sheep and 781 goats located on seven and ten farms, respectively, in the central eastern region of China. The corresponding sequences obtained in this study were subject to molecular analysis for subtype and allele identification of Blastocystis sp., and species and genotype confirmation of P. hominis. RESULTS: The occurrence of Blastocystis sp. was 6.0% (50/832) in sheep and 0.3% (2/781) in goats. The most predominant subtype (ST) of Blastocystis sp. in sheep was ST10 (50.0%), followed by ST14 (20%), ST5 (16%), novel sequence 1 (6%), novel sequence 4 (4%), novel sequence 2 (2%) and novel sequence 3 (2%). However, only ST1 was observed in goats. No mixed infections with different subtypes were found in this study. The 18S alleles showed allele 2 (100%) for ST1; allele 115 (75%) for ST5; and no match allele for ST5 (25%), ST10 (100%), ST14 (100%), novel sequence 1 (100%), novel sequence 2 (100%), novel sequence 3 (100%), and novel sequence 4 (100%) on the Blastocystis subtype (18S) and Sequence Typing (MLST) database. For P. hominis, two goats (0.3%) and zero sheep (0%) were identified as positive in this study. The 18S rRNA gene sequences of two P. hominis isolates from goats displayed 100% identity to type CC1, found previously in dogs, monkeys and humans. CONCLUSIONS: These results provide the detailed data on the occurrence and molecular epidemiology of Blastocystis sp. and P. hominis in sheep and goats in China. They also contribute to and expand our knowledge of the Blastocystis sp. and P. hominis epidemiology around the world. PMID- 29454367 TI - Reassessment of the capacity of the HIV-1 Env cytoplasmic domain to trigger NF kappaB activation. AB - The cytoplasmic domain of lentiviral Envelopes (EnvCD) ensures Env incorporation into nascent virions and regulates Env trafficking to and from the plasma membrane. It has also been reported to promote transcription from the viral LTR both directly and indirectly. Noticeably, the HIV-1 and SIVmac239 EnvCDs were described to trigger nuclear translocation of NF-kappaB (Postler, Cell Host Microbes 2012). Given the paramount importance of identifying viral and host factors regulating HIV transcription, cellular signaling pathways and latency, and given that viral replication capacity is dependent on Env, we asked whether HIV EnvCDs from different HIV-1 subtypes differently modulated NF-kappaB. To that aim, we evaluated the ability of primary HIV-1 Envs from subtypes B and C to activate the NF-kappaB pathway. Primary subtype B and C Envs all failed to activate the NF-kappaB pathway. In contrast, when the EnvCD of HIV-1 Envs was fused to the the CD8-alpha chain, it induced ~ 10-fold increase in NF-kappaB induction, and this increase was much stronger with a truncated form of the HIV EnvCD lacking the 76 C-terminal residues and containing the proposed TAK-1 binding domain. Our results indicate that the HIV-1 EnvCD is unlikely to trigger the NF-kappaB pathway in its native trimeric form. PMID- 29454368 TI - Survey indicated that core outcome set development is increasingly including patients, being conducted internationally and using Delphi surveys. AB - BACKGROUND: There are numerous challenges in including patients in a core outcome set (COS) study, these can vary depending on the patient group. This study describes current efforts to include patients in the development of COS, with the aim of identifying areas for further improvement and study. METHODS: Using the COMET database, corresponding authors of COS projects registered or published from 1 January 2013 to 2 February 2017 were invited via a personalised email to participate in a short online survey. The survey and emails were constructed to maximise the response rate by following the academic literature on enhancing survey responses. Personalised reminder emails were sent to non-responders. This survey explored the frequency of patient input in COS studies, who was involved, what methods were used and whether or not the COS development was international. RESULTS: One hundred and ninety-two COS developers were sent the survey. Responses were collected from 21 February 2017 until 7 May 2017. One hundred and forty-six unique developers responded, yielding a 76% response rate and data in relation to 195 unique COSs (as some developers had worked on multiple COSs). Of focus here are their responses regarding 162 COSs at the published, completed or ongoing stages of development. Inclusion of patient participants was indicated in 87% (141/162) of COSs in the published completed or ongoing stages and over 94% (65/69) of ongoing COS projects. Nearly half (65/135) of COSs included patient participants from two or more countries and 22% (30/135) included patient participants from five or more countries. The Delphi survey was reported as being used singularly or in combination with other methods in 85% (119/140) of projects. Almost a quarter (16/65) of ongoing studies reported using a combination of qualitative interviews, Delphi survey and consensus meeting. CONCLUSIONS: These findings indicated that the Delphi survey is the most popular method of facilitating patient participation, while the combination of qualitative interviews, Delphi survey and consensus meetings is the most popular combination of methods. The increased inclusion of patient participants in the development of COSs is encouraging, as is the international approach to COS development that some developers are adopting. PMID- 29454369 TI - Evaluation of piezocision and laser-assisted flapless corticotomy in the acceleration of canine retraction: a randomized controlled trial. AB - BACKGROUND: To evaluate the effectiveness of two minimally invasive surgical procedures in the acceleration of canine retraction: piezocision and laser assisted flapless corticotomy (LAFC). METHODS: Trial design: A single-centre randomized controlled trial with a compound design (two-arm parallel-group design and a split-mouth design for each arm). PARTICIPANTS: 36 Class II division I patients (12 males, 24 females; age range: 15 to 27 years) requiring first upper premolars extraction followed by canine retraction. INTERVENTIONS: piezocision group (PG; n = 18) and laser-assisted flapless corticotomy group (LG; n = 18). A split-mouth design was applied for each group where the flapless surgical intervention was randomly allocated to one side and the other side served as a control side. OUTCOMES: the rate of canine retraction (primary outcome), anchorage loss and canine rotation, which were assessed at 1, 2, 3 and 4 months following the onset of canine retraction. Also the duration of canine retraction was recorded. Random sequence: Computer-generated random numbers. Allocation concealment: sequentially numbered, opaque, sealed envelopes. Blinding: Single blinded (outcomes' assessor). RESULTS: Seventeen patients in each group were enrolled in the statistical analysis. The rate of canine retraction was significantly greater in the experimental side than in the control side in both groups by two-fold in the first month and 1.5-fold in the second month (p < 0.001). Also the overall canine retraction duration was significantly reduced in the experimental side as compared with control side in both groups about 25% (p <= 0.001). There were no significant differences between the experimental and the control sides regarding loss of anchorage and upper canine rotation in both groups (p > 0.05). There were no significant differences between the two flapless techniques regarding the studied variables during all evaluation times (p > 0.05). CONCLUSIONS: Piezocision and laser-assisted flapless corticotomy appeared to be effective treatment methods for accelerating canine retraction without any significant untoward effect on anchorage or canine rotation during rapid retraction. TRIALS REGISTRATION: ClinicalTrials.gov (Identifier: NCT02606331 ). PMID- 29454370 TI - Isolation of a novel Rhabdovirus from an insectivorous bat (Pipistrellus kuhlii) in Italy. AB - BACKGROUND: Rhabdoviridae is one of the most ecologically diverse families of RNA viruses which can infect a wide range of vertebrates and invertebrates. Bats, among mammals, are pointed to harbor a significantly higher proportion of unknown or emerging viruses with zoonotic potential. Herein, we report the isolation of a novel rhabdovirus, detected in the framework of a virological survey on bats implemented in North Italy. METHODS: Virus isolation and identification were performed on samples of 635 bats by using cell cultures, negative staining electron microscopy and PCRs for different viruses. NGS was commonly performed on cell culture supernatants showing cytopathic effect or in case of samples resulted positive by at least one of the PCRs included in the diagnostic protocol. RESULTS: A rhabdovirus was isolated from different organs of a Pipistrellus kuhlii. Virus identification was obtained by electron microscopy and NGS sequencing. The complete genome size was 11,774 nt comprised 5 genes, encoding the canonical rhabdovirus structural proteins, and an additional transcriptional unit (U1) encoding a hypothetical small protein (157aa) (3'-N-P-M G-U1-L-5'). The genome organization and phylogenetic analysis suggest that the new virus, named Vaprio virus (VAPV), belongs to the recently established genus Ledantevirus (subgroup B) and it is highly divergent to its closest known relative, Le Dantec virus (LDV) (human, 1965 Senegal). A specific RT-PCR amplifying a 350 bp fragment of the ORF 6 gene, encoding for L protein, was developed and used to test retrospectively a subset of 76 bats coming from the same area and period, revealing two more VAPV positive bats. CONCLUSIONS: VAPV is a novel isolate of chiropteran rhabdovirus. Genome organization and phylogenetic analyses demonstrated that VAPV should be considered a novel species within the genus Ledantevirus for which viral ecology and disease associations should be investigated. PMID- 29454371 TI - Auditory effects of autologous fat graft for TORP stabilization in the middle ear: a cadaveric study. AB - BACKGROUND: Total ossicular replacement prostheses (TORP) are often used to re establish ossicular coupling of sound in an ear lacking a stapes supra-structure. The use of TORPs, however, is associated with a 2/3 five year failure rate due to their anatomic instability over time in the middle ear. The use of autologous fat to try and stabilize TORPs may improve long-term results with this challenging ossicular reconstruction technique. METHODS: A cadaveric temporal bone model was developed and laser Doppler vibrometry was used to measure and record round window membrane vibration in response to sound stimulation under the following conditions: normal middle ear, middle ear filled with fat, normal middle ear with TORP prosthesis, TORP prosthesis with fat around its distal end and TORP prosthesis with fat filling the middle ear. Fourteen temporal bones were used. RESULTS: There was a significant decrease in round window membrane velocity after filling the middle ear with fat in both the normal middle ear (- 8.6 dB; p < 0.0001) and prosthesis conditions (- 13.7 dB; p < 0.0001). However, there was no significant drop in round window membrane velocity associated with using fat around the distal end of the TORP prosthesis as compared to the prosthesis without fat condition (p > 0.05). CONCLUSIONS: Autologous fat around the distal end of a TORP prosthesis may not be associated with any additional hearing loss, as demonstrated in this cadaveric model. The additional hearing loss potentially caused by using fat to completely surround the prosthesis and fill the middle ear is probably not clinically acceptable at this time, especially given the unknown way in which the fat will atrophy over time in this context. PMID- 29454372 TI - A novel combination of bortezomib, lenalidomide, and clarithromycin produced stringent complete response in refractory multiple myeloma complicated with diabetes mellitus - clinical significance and possible mechanisms: a case report. AB - BACKGROUND: In general, dexamethasone is a required component drug in various combination chemotherapies for treating multiple myeloma, and its efficacy has been widely recognized. However, administration of dexamethasone is known to cause various adverse effects including hyperglycemia which requires insulin therapy. During the course of treatment, we developed a novel effective dexamethasone-free combination regimen and evaluated it for its effect in multiple myeloma. CASE PRESENTATION: We report a case of 68-year-old Japanese woman with refractory advanced Bence-Jones-lambda type multiple myeloma associated with diabetes mellitus. Various combination regimens were carried out, but the response to some regimens was insufficient or others containing dexamethasone, although effective, were inappropriate to continue due to aggravation of diabetes mellitus. Thus, we developed a dexamethasone-free, short dosing-period regimen consisting of bortezomib, lenalidomide, and clarithromycin. This regimen was found to be highly effective and succeeded in achieving stringent complete response. CONCLUSIONS: The successful dexamethasone-free regimen clearly shows that dexamethasone is not a requisite component in treating multiple myeloma, and it can be substituted with clarithromycin. This regimen is particularly useful for treating patients with multiple myeloma associated with diabetes mellitus. PMID- 29454373 TI - Subclinical hypothyroidism in children: is it always subclinical? AB - Aim of this commentary is to report current knowledges on the main clinical and metabolic abnormalities which might be observed in children with longstanding and untreated subclinical hypothyroidism (SH) and to comment the most recent views about natural evolution of thyroid function in the cases with either idiopathic or Hashimoto's thyroiditis-related SH. On the basis of these preliminary remarks, the essential guidelines for an appropriate and tailored management of SH children are also proposed. PMID- 29454374 TI - Effects of umbilical cord blood cells, and subtypes, to reduce neuroinflammation following perinatal hypoxic-ischemic brain injury. AB - BACKGROUND: It is well understood that hypoxic-ischemic (HI) brain injury during the highly vulnerable perinatal period can lead to cerebral palsy, the most prevalent cause of chronic disability in children. Recently, human clinical trials have reported safety and some efficacy following treatment of cerebral palsy using umbilical cord blood (UCB) cells. UCB is made up of many different cell types, including endothelial progenitor cells (EPCs), T regulatory cells (Tregs), and monocyte-derived suppressor cells (MDSCs). How each cell type contributes individually towards reducing neuroinflammation and/or repairing brain injury is not known. In this study, we examined whether human (h) UCB, or specific UCB cell types, could reduce peripheral and cerebral inflammation, and promote brain repair, when given early after perinatal HI brain injury. METHODS: HI brain injury was induced in postnatal day (PND) 7 rat pups and cells were administered intraperitoneally on PND 8. Behavioral testing was performed 7 days post injury, and then, brains and spleens were collected for analysis. RESULTS: We found in vitro that all UCB cell types, except for EPCs, were immunomodulatory. Perinatal HI brain injury induced significant infiltration of CD4+ T cells into the injured cerebral hemisphere, and this was significantly reduced by all hUCB cell types tested. Compared to HI, UCB, Tregs, and EPCs were able to reduce motor deficits, reduce CD4+ T cell infiltration into the brain, and reduce microglial activation. In addition to the beneficial effects of UCB, EPCs also significantly reduced cortical cell death, returned CD4+ T cell infiltration to sham levels, and reduced the peripheral Th1-mediated pro inflammatory shift. CONCLUSION: This study highlights that cells found in UCB is able to mediate neuroinflammation and is an effective neuroprotective therapy. Our study also shows that particular cells found in UCB, namely EPCs, may have an added advantage over using UCB alone. This work has the potential to progress towards tailored UCB therapies for the treatment of perinatal brain injury. PMID- 29454375 TI - "Sweeter than a rose", at least to Triatoma phyllosoma complex males (Triatominae: Reduviidae). AB - BACKGROUND: The Triatoma phyllosoma complex of Trypanosoma cruzi vectors (Triatominae: Reduviidae) is distributed in both Neotropical and Nearctic bioregions of Mexico. METHODS: Volatile organic compounds emitted by disturbed Triatoma longipennis, Triatoma pallidipennis and Triatoma phyllosoma, and from their Brindley's and metasternal glands, were identified using solid-phase microextraction coupled with gas chromatography-mass spectrometry. RESULTS: Disturbed bugs and the metasternal glands from T. phyllosoma released or had significantly fewer compounds than T. longipennis and T. pallidipennis. Isobutyric acid was the most abundant compound secreted by disturbed bugs of the three species, while Brindley's glands of all species produced another four compounds: propanoic acid, isobutyric acid, pentyl butanoate, and 2-methyl hexanoic acid. Two novel compounds, both rose oxide isomers, were produced in MGs and released only by disturbed females of all three species, making this the first report in Triatominae of these monoterpenes. The principal compound in MGs of both sexes of T. longipennis and T. phyllosoma was 3-methyl-2-hexanone, while cis-rose oxide was the principal compound in T. pallidipennis females. The major components in male effluvia of T. pallidipennis were 2-decanol and 3-methyl-2 hexanone. CONCLUSION: Discriminant analysis of volatile organic compounds was significant, separating the three species and was consistent with morphological and genetic evidence for species distinctions within the complex. PMID- 29454376 TI - Seroprevalence of Neospora caninum-specific antibodies in German breeding bitches. AB - BACKGROUND: Neospora caninum is an intracellular obligate apicomplexan parasite responsible for multisystemic lesions in dogs. Being definitive hosts and reservoirs, dogs excrete environmentally resistant oocysts. Breeding bitches represent a susceptible dog group and infected bitches may spread this parasite through transplacental transmission. RESULTS: A total of 218 serum samples of German breeding bitches were collected to determine the presence of N. caninum. Antibodies were detected in 16 (7.33%) bitches using a commercial indirect enzyme linked immunosorbent assay (ELISA). Immunoblotting analysis confirmed all seropositive samples detected by ELISA, proving that the animals were infected with N. caninum. The owners were interviewed regarding breed, age, environment, type, vaccine status, feeding habits and the presence of reproductive disorders. Seropositive animals were between the ages of two to seven years; three of them were kept in kennels while the others were household dogs, one of which was additionally a hunting dog. Owners of four seropositive bitches reported one gestation, while multiple pregnancies had been recorded for the other twelve bitches. Fourteen bitches were regularly vaccinated and six were fed with fresh raw meat. CONCLUSIONS: Although the results confirmed a low incidence of N. caninum seropositive German breeding bitches, further epidemiological and surveillance studies are required to complement our findings regarding the current situation of neosporosis in this specific canine population of Germany. PMID- 29454377 TI - Chronic recurrent multifocal osteomyelitis: a case report. AB - BACKGROUND: Chronic recurrent multifocal osteomyelitis (CRMO), also known as chronic nonbacterial osteomyelitis, is a rare, noninfectious inflammatory disorder that causes multifocal bone lesions with swelling and pain. Lytic and sclerotic bone lesions could be found on X-ray. Short tau inversion recovery magnetic resonance imaging (STIR MRI) shows bone marrow oedema, bone expansion, lytic areas and periosteal reaction. CRMO is characterized by periodic exacerbations and remissions of unclear/unknown pathogenesis. CASE PRESENTATION: A 10 years old girl, suffering from pain in her right shoulder since the age of 9 years presented to our Department. Thanks to clinical data, laboratoristic and radiological findings and bone biopsy CRMO was diagnosed. So patient started anti inflammatory treatment and her conditions improved. CONCLUSIONS: In a child with bone pain should be considered also rare condition as CRMO to perform a correct diagnosis and start an adequate treatment avoiding complications such as bone damage. This condition should be suspected in a child with recurrent bone pain, modest increase of inflammatory indices, lytic or sclerotic bone lesion on X Ray. Typical CRMO localizations are metaphyses of long bones, pelvis, clavicle, vertebral column, sternum, ribs, jaw, but any bone can be involved. The most common CRMO differential diagnosis is represented by infections, malignant bone tumors, Langerhans Cells Histiocytosis (LCH). PMID- 29454378 TI - Do employees benefit from collaborations between out of hours general practitioners and emergency departments? AB - BACKGROUND: In an attempt to redirect patients who are inappropriately attending hospital emergency departments (ED) and in doing so provide the right care at the right place, out-of-hours GP (General Practitioner) services and EDs increasingly collaborate in Urgent Care Collaborations (UCCs). Work satisfaction is an important factor in analysing the impact of this organisational change. The objective of this study is, firstly, to discover if there is a difference in the employee experiences between those working in UCCs and those in traditional out of-hours services in which EDs and out-of-hours GP services operate separately (i.e. "usual care"). Secondly, we would like to identify which factors affect employees' experiences in these settings. METHODS: This study followed a cross sectional study design, comparing usual care with UCCs. Data regarding employee experiences were collected from physicians, nurses, nurse practitioners, medical assistants and front desk personnel, by means of a questionnaire with scales regarding quality, workload and co-operation between the out-of-hours GP service and ED. Independent samples t-tests were used to determine mean differences between the settings. Multiple linear regression analyses were performed to test which items affected the perceived quality, workload and co-operation. RESULTS: The results showed that mutual co-operation alone was perceived as significantly better in UCCs compared to usual care. If divided between employers, no differences were found in the employee experiences working in out-of-hours GP services. ED employees in UCCs experienced a significantly better co-operation with their GP colleagues than their peers in the usual care setting, but also a higher workload. Remarkably, ED employees were less satisfied in general. The multiple regression model showed that perceived quality, workload and co operation were interrelated. Co-operation was the only aspect that was rated higher in the UCC setting. CONCLUSION: While perceived quality is equal and co operation between out-of-hours GP service and ED is better, the objective and perceived ED workload was higher in UCCs compared to usual care. Though UCCs relieve the pressure on EDs concerning the number of patients, they seem to aggravate the workload. EDs need to be careful not to excessively adjust staff capacity when responding to lower numbers of patients. PMID- 29454379 TI - Resistance to deltamethrin by domestic and wild Triatoma infestans populations in the municipality of Toro Toro, Potosi, Bolivia. AB - BACKGROUND: Chemical control with pyrethroid insecticides has been effective in reducing endemic areas of distribution of Triatoma infestans in the Southern Cone, as well as Bolivia; this had considerably reduced the infestation of households in a large part of the territory. Nowadays, areas such as the Chaco and the Inter-Andean Valleys are regions where the reach of vector control strategies is becoming limited, and infestations of insecticide-treated households are reported more often. The objective of this study was to determine if the persistence of T. infestans stems from changes in the susceptibility of its toxicological profile in four communities in the municipality of Toro Toro, Potosi, Bolivia. METHODS: Susceptibility to deltamethrin of wild and domestic populations of T. infestans was evaluated in two stages (16 populations before and 13 populations after spraying) among DUs (structures in the intra- and peridomicile) and wild ecotopes, in four communities. Serial dilutions of deltamethrin in acetone (0.2 MUl) were applied topically on standardized first stage nymphs. Dose-response results were analyzed with the software PoloPlus and the relationships between lethal doses (LD) and resistance ratios (RR50) were determined. RESULTS: Different degrees of RR50 were detected among the populations before and after spraying (25.66-54.70 and 21.91-40.67, respectively), as well as in different ecotopes within a DU (DU JC 3, 28.06 36.13, in mixed structures of corrals and chicken coops; and DU JG 3, 46.27 25.70, in kitchen roofs), or in the wild environment of the community JG Sil (29.21-40.67). The mortality of insects undergoing diagnostic dose (DD) was never higher than 34%. CONCLUSION: The results obtained in this study showed resistance of T. infestans to deltamethrin in four communities, hence the complexity of this phenomenon is not only limited to the level of communities, but also applies to the microgeographical level, as in different ecotopes present within the DUs. This phenomenon should be considered while planning the activities of control programs. PMID- 29454380 TI - Quality of life, satisfaction and outcomes after ministernotomy versus full sternotomy isolated aortic valve replacement (QUALITY-AVR): study protocol for a randomised controlled trial. AB - BACKGROUND: During the last decade, the use of ministernotomy in cardiac surgery has increased. Quality of life and patient satisfaction after ministernotomy have never been compared to conventional full sternotomy in randomised trials. The aim of the study is to determine if this minimally invasive approach improves quality of life, satisfaction and clinical morbimortality outcomes. METHODS/DESIGN: The QUALITY-AVR trial is a single-blind, single-centre, independent, and pragmatic randomised clinical trial comparing ministernotomy ("J" shaped upper hemisternotomy toward right 4th intercostal space) to full sternotomy in patients with isolated severe aortic stenosis scheduled for elective aortic valve replacement. One hundred patients will be randomised in a 1:1 computational fashion. Sample size was determined for the primary end point with alpha error of 0.05 and with power of 90% in detecting differences between intervention groups of >= 0.10 points in change from baseline quality of life Questionnaire EuroQOL index (EQ-5D-5 L(r)), measured at 1, 6 or 12 months. Secondary endpoints are: the differences in change from other baseline EQ-5D-5 L(r) utilities (visual analogue scale, Health Index and Severity Index), cardiac surgery specific satisfaction questionnaire (SATISCORE(r)), a combined safety endpoint of four major adverse complications at 1 month (all-cause mortality, acute myocardial infarction, neurologic events and acute renal failure), bleeding through drains within the first 24 h, intubation time, postoperative hospital and intensive care unit length of stay, transfusion needs during the first 72 h and 1-year survival rates. Clinical follow up is scheduled at baseline, 1, 6, and 12 months after randomization. All clinical outcomes are recorded following the Valve Academic Research Consortium 2 criteria. DISCUSSION: The QUALITY-AVR trial aims to test the hypothesis that ministernotomy improves quality of life, satisfaction and clinical outcomes in patients referred for isolated aortic valve replacement. Statistically significant differences favouring ministernotomy could modify the surgical "gold standard" for aortic stenosis surgery, and subsequently the need to change the control group in transcatheter aortic valve implantation trials. Recruitment started on 18 March 2016. In November 2017, 75 patients were enrolled. TRIAL REGISTRATION: ClinicalTrials.gov , NCT02726087 . Registered on 13 March 2016. PMID- 29454381 TI - Human cerebrovascular function in health and disease: insights from integrative approaches. AB - BACKGROUND: The marked increase in the size of the brain, and consequently, in neural processing capability, throughout human evolution is the basis of the higher cognitive function in humans. However, greater neural, and thus information processing capability, comes at a significant metabolic cost; despite its relatively small size, the modern human brain consumes almost a quarter of the glucose and oxygen supply in the human body. Fortunately, several vascular mechanisms ensure sufficient delivery of glucose and oxygen to the active neural tissue (neurovascular coupling), prompt removal of neural metabolic by-products (cerebral vasoreactivity), and constant global blood supply despite daily variations in perfusion pressure (cerebral autoregulation). The aim of this review is to provide an integrated overview of the available data on these vascular mechanisms and their underlying physiology. We also briefly review modern experimental approaches to assess these mechanisms in humans, and further highlight the importance of these mechanisms for humans' evolutionary success by providing examples of their healthy adaptations as well as pathophysiological alterations. CONCLUSIONS: Data reviewed in this paper demonstrate the importance of the cerebrovascular function to support humans' unique ability to form new and different interactions with each other and their surroundings. This highlights that there is much insight into the neural and cognitive functions that could be gleaned from interrogating the cerebrovascular function. PMID- 29454382 TI - High risk human papillomavirus prevalence and genotype distribution among women infected with HIV in Manaus, Amazonas. AB - BACKGROUND: Human immunodeficiency virus (HIV)-positive women have a high prevalence of human papillomavirus (HPV), and are infected with a broader range of HPV types than HIV-negative women. We aimed to determine the prevalence of cervical cytologic abnormalities, high-risk (HR)-HPV prevalence, type distribution according to the severity of cervical lesions and CD4 cell count and identify factors associated with HR-HPV infection among women living with HIV in Manaus, Amazonas. METHODS: We enrolled 325 women living with HIV that attended an infectious diseases referral hospital. Each woman underwent a gynecological exam, cervical cytology, HR-HPV detection by Polymerase chain Reaction (PCR) using the BD OnclarityTM HPV Assay, colposcopy and biopsy, when necessary. We assessed the associations between potential risk factors and HR-HPV infection. RESULTS: Overall, 299 (92.0%) women had a PCR result. The prevalence of HR-HPV- infection was 31.1%. The most prevalent HR-HPV types were: 56/59/66 (32.2%), 35/39/68 (28.0%), 52 (21.5%), 16 (19.4%), and 45 (12.9%). Among the women with HR-HPV infection (n = 93), 43.0% had multiple infections. Women with HPV infection showed higher prevalence of cervical abnormalities than that HPV-negative (LSIL: 22.6% vs. 1.5%; HSIL: 10.8% vs. 0.0%). The prevalence of HR-HPV among women with cytological abnormalities was 87.5% for LSIL and 100.0% for HSIL. Women with CD4 < 200 cell/mm3 showed the highest HR-HPV prevalence (59.3%) although this trend was not statistically significant (p-value = 0.62). The mean CD4 cell count decreased with increasing severity of cervical lesions (p-value = 0.001). The multivariable analysis showed that increasing age was associated with a decreased risk of HR-HPV infection with an adjusted prevalence odds ratio of 0.9 (95.0% CI: 0.9-1.0, p-value: 0.03) for each additional year. The only factor statistically significant associated with HR-HPV infection was CD4 cell count. CONCLUSIONS: HR HPV and abnormal cytology prevalence are high among women in the Amazonas. The low CD4 cell count was an important determinant of HPV infection and abnormal cytological findings. HPV quadrivalent vaccination used in Brazil might not offer protection for an important fraction of HPV-related disease burden in women living with HIV. This is partly explained by the high presence of non targeted vaccine HR-HPVs, such as the HPV genotype groups 56/59/66, 35/39/68 and individually HPV-52 and HPV-45, some of which contribute to high-grade lesion. PMID- 29454383 TI - Multidimensional needs of patients living and dying with heart failure in Kenya: a serial interview study. AB - BACKGROUND: Heart failure is an emerging challenge for Sub Saharan Africa. However, research on patients' needs and experiences of care is scarce with little evidence available to support and develop services. We aimed to explore the experiences of patients living and dying with heart failure in Kenya. METHODS: We purposively recruited 18 patients admitted with advanced heart failure at a rural district hospital in Kenya. We conducted serial in depth interviews with patients at 0, 3 and 6 months after recruitment, and conducted bereavement interviews with carers. Interviews were recorded, transcribed into English and analyzed using a thematic approach, assisted by Nvivo software package. RESULTS: Forty-four interviews were conducted. Patients experienced physical, psychosocial, spiritual and financial distress. They also had unmet needs for information about their illness, how it would affect them and how they could get better. Patients experience of and their interpretation of symptoms influenced health care seeking. Patients with acute symptoms sought care earlier than those with more gradual symptoms which tended to be normalised as part of daily life or assumed to be linked to common treatable conditions. Nearly all patients expected to be cured and were frustrated by a progressive illness poorly responsive to treatment. Accumulating costs was a barrier to continuity of care and caused tensions in social relationships. Patients valued information on the nature of their illness, prognosis, self-care, lifestyle changes and prevention strategies, but this was rarely available. CONCLUSIONS: This is the first in depth study to explore the experiences of people living with advanced heart failure in Kenya. This study suggests that patients would benefit from holistic care, such as a palliative approach that is aimed at providing multidimensional symptom management. A palliative approach to services should be provided alongside chronic disease management aimed at primary prevention of risk factors, and early identification and initiation of disease modifying therapy. Further research is needed to determine best practice for integrating palliative care for people living and dying with heart failure.

AB - BACKGROUND: There is a growing support for the stance that patients and research participants should have better and easier access to their raw (uninterpreted) genomic sequence data in both clinical and research contexts. MAIN BODY: We review legal frameworks and literature on the benefits, risks, and practical barriers of providing individuals access to their data. We also survey genomic sequencing initiatives that provide or plan to provide individual access. Many patients and research participants expect to be able to access their health and genomic data. Individuals have a legal right to access their genomic data in some countries and contexts. Moreover, increasing numbers of participatory research projects, direct-to-consumer genetic testing companies, and now major national sequencing initiatives grant individuals access to their genomic sequence data upon request. CONCLUSION: Drawing on current practice and regulatory analysis, we outline legal, ethical, and practical guidance for genomic sequencing initiatives seeking to offer interested patients and participants access to their raw genomic data. PMID- 29454385 TI - Tranexamic acid in total shoulder arthroplasty and reverse shoulder arthroplasty: a systematic review and meta-analysis. AB - BACKGROUND: The effects of tranexamic acid (TXA) in the setting of shoulder arthroplasty are unclear. The objective of this study was to examine the effects of TXA in reducing the need for blood transfusions and blood loss in patients undergoing primary total shoulder arthroplasty (TSA) and reverse total shoulder arthroplasty (RTSA). METHODS: We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) and retrospective cohort studies (RCS) that compared outcomes of patients who did and did not receive TXA during TSA or RTSA. We searched Cochrane Central Register of Controlled Trials, EMBASE, and MEDLINE for relevant studies. We assessed the risk of bias of the included studies and calculated pooled risk estimates. The primary outcome was transfusion rate, and secondary outcomes were changes in hemoglobin, estimated total blood loss (ETBL), blood loss via drainage, operative time, hospital stay, overall complications, and thromboembolic events. RESULTS: We identified 3 RCTs and 3 RCS including 677 patients with 680 shoulders (343 TXA and 337 non-TXA). The random effects model meta-analysis showed that TXA group had a lower transfusion rate (risk ratio (RR) 0.34, 95% CI 0.14 to 0.79), less change in hemoglobin (mean difference (MD) -0.64 g/dl, 95% CI -0.81 to - 0.46), and reduced ETBL (MD -249.24 ml, 95% CI -338.74 to - 159.74). In patients with RTSA, the TXA group had a lower transfusion rate (RR 0.28, 95% CI 0.14 to 0.79), less ETBL (MD -249.15 ml, 95% CI -426.60 to - 71.70), less change in hemoglobin (MD - 0.64 g/dl, 95% CI -0.86 to - 0.42), and less blood loss via drainage (MD - 84.56 ml, 95% CI -145.72.14 to - 23.39) than non-TXA group. CONCLUSIONS: The use of TXA in primary shoulder arthroplasty appears safe, and can reduce transfusion rate, changes in hemoglobin, and perioperative total blood loss, especially in patients with RTSA. LEVEL OF EVIDENCE: Systematic Review and meta-analysis, III. PMID- 29454386 TI - Telomere elongation protects heart and lung tissue cells from fatal damage in rats exposed to severe hypoxia. AB - BACKGROUND: The effects of acute hypoxia at high altitude on the telomere length of the cells in the heart and lung tissues remain unclear. This study aimed to investigate the change in telomere length of rat heart and lung tissue cells in response to acute exposure to severe hypoxia and its role in hypoxia-induced damage to heart and lung tissues. METHODS: Forty male Wistar rats (6-week old) were randomized into control group (n = 10) and hypoxia group (n = 30). Rats in control group were kept at an altitude of 1500 m, while rats in hypoxia group were exposed to simulated hypoxia with an altitude of 5000 m in a low-pressure oxygen chamber for 1, 3, and 7 days (n = 10). The left ventricular and right middle lobe tissues of each rat were collected for measurement of telomere length and reactive oxygen species (ROS) content, and the mRNA and protein levels of telomerase reverse transcriptase (TERT), hypoxia-inducible factor1alpha (HIF 1alpha), and hypoxia-inducible factor1alpha (HIF-2alpha). RESULTS: Increased exposure to hypoxia damaged rat heart and lung tissue cells and increased ROS production and telomere length. The mRNA and protein levels of TERT and HIF 1alpha were significantly higher in rats exposed to hypoxia and increased with prolonged exposure; mRNA and protein levels of HIF-2alpha increased only in rats exposed to hypoxia for 7 days. TERT was positively correlated with telomere length and the levels of HIF-1alpha but not HIF-2alpha. CONCLUSIONS: Acute exposure to severe hypoxia causes damage to heart and lung tissues due to the production of ROS but promotes telomere length and adaptive response by upregulating TERT and HIF-1alpha, which protect heart and lung tissue cells from fatal damage. PMID- 29454387 TI - The transcriptome response of the ruminal methanogen Methanobrevibacter ruminantium strain M1 to the inhibitor lauric acid. AB - OBJECTIVE: Lauric acid (C12) is a medium-chain fatty acid that inhibits growth and production of the greenhouse gas methane by rumen methanogens such as Methanobrevibacter ruminantium. To understand the inhibitory mechanism of C12, a transcriptome analysis was performed in M. ruminantium strain M1 (DSM 1093) using RNA-Seq. RESULTS: Pure cell cultures in the exponential growth phase were treated with 0.4 mg/ml C12, dissolved in dimethyl sulfoxide (DMSO), for 1 h and transcriptomic changes were compared to DMSO-only treated cells (final DMSO concentration 0.2%). Exposure to C12 resulted in differential expression of 163 of the 2280 genes in the M1 genome (maximum log2-fold change 6.6). Remarkably, C12 hardly affected the expression of genes involved in methanogenesis. Instead, most affected genes encode cell-surface associated proteins (adhesion-like proteins, membrane-associated transporters and hydrogenases), and proteins involved in detoxification or DNA-repair processes. Enrichment analysis on the genes regulated in the C12-treated group showed a significant enrichment for categories 'cell surface' and 'mobile elements' (activated by C12), and for the categories 'regulation' and 'protein fate' (represssed). These results are useful to generate and test specific hypotheses on the mechanism how C12 affects rumen methanogens. PMID- 29454388 TI - DOCK7-ANGPTL3 SNPs and their haplotypes with serum lipid levels and the risk of coronary artery disease and ischemic stroke. AB - BACKGROUND: Little is known about the association of the dedicator of cytokinesis 7 (DOCK7 rs1748195) and angiopoietin like 3 (ANGPTL3 rs12563308) single nucleotide polymorphisms (SNPs) and their haplotypes with serum lipid levels and the risk of coronary artery disease (CAD) and ischemic stroke (IS) in the Chinese populations. This study aimed to detect such association in a Southern Chinese Han population. METHODS: This study included 1728 subjects (CAD, 568; IS, 539; and controls, 621). Genotypes of the two SNPs were determined by the Snapshot technology. RESULTS: The genotypic and allelic frequencies of the rs1748195 SNP were different between CAD patients and controls (P < 0.05 for each), the rs1748195G allele frequency was higher in CAD patients than in controls (27.6% vs. 23.6%, P = 0.024). The genotypic frequencies of the rs12563308 SNP were also different between CAD patients and controls (P = 0.021). The rs1748195 SNP was associated with an increased risk of CAD after controlling for potential confounders and Bonferroni correction (P < 0.025 considered statistically significant; Recessive: OR = 1.79, 95% CI = 1.04-3.06, P = 0.017; Log-additive: OR = 1.27, 95% CI = 1.02-1.57, P = 0.014), whereas the rs12563308 SNP was associated with a decreased risk of CAD (Dominant: OR = 0.69, 95% CI = 0.45-0.94, P = 0.011; Log-additive: OR = 0.73, 95% CI = 0.49-0.89, P = 0.009). The rs1748195 SNP was also associated with an increased risk of severity to coronary artery atherosclerosis (Dominant: OR = 1.45, 95% CI = 1.07-2.11, P = 0.017; Log additive: OR = 1.35, 95% CI = 1.09-1.82, P = 0.013). The interactions of SNP environment on serum lipid levels and the risk of severity to coronary artery atherosclerosis, CAD and IS were noted. The rs1748195G-rs12563308T haplotype was associated with an increased angiographic severity to coronary artery atherosclerosis (OR = 1.46, 95% CI = 1.05-2.03), and the risk of CAD (OR = 1.37, 95% CI = 1.08-1.74). The interactions of haplotype-hypertension on the risk of CAD and haplotype-drinking on the risk of CAD/IS were observed. CONCLUSIONS: These results suggest that the DOCK-ANGPTL3 SNPs and their haplotypes were associated with the angiographic severity to coronary artery atherosclerosis and the risk of CAD and IS in the Southern Chinese Han population. PMID- 29454389 TI - Recruitment of racial and ethnic minorities to clinical trials conducted within specialty clinics: an intervention mapping approach. AB - BACKGROUND: Despite efforts to increase diversity in clinical trials, racial/ethnic minority groups generally remain underrepresented, limiting researchers' ability to test the efficacy and safety of new interventions across diverse populations. We describe the use of a systematic framework, intervention mapping (IM), to develop an intervention to modify recruitment behaviors of coordinators and specialist investigators with the goal of increasing diversity in trials conducted within specialty clinics. To our knowledge IM has not been used in this setting. METHODS: The IM framework was used to ensure that the intervention components were guided by health behavior theories and the evidence. The IM steps consisted of (1) conducting a needs assessment, (2) identification of determinants and objectives, (3) selection of theory-informed methods and practical applications, (4) development and creation of program components, (5) development of an adoption and implementation plan, and (6) creation of an evaluation plan. RESULTS: The intervention included five educational modules, one in-person and four web-based, plus technical assistance calls to coordinators. Modules addressed the intervention rationale, development of clinic-specific plans to obtain minority-serving physician referrals, physician-centered and patient-centered communication, and patient navigation. The evaluation, a randomized trial, was recently completed in 50 specialty clinics and is under analysis. CONCLUSIONS: Using IM we developed a recruitment intervention that focused on building relationships with minority-serving physicians to encourage minority patient referrals. IM enhanced our understanding of factors that may influence minority recruitment and helped us integrate strategies from multiple disciplines that were relevant for our audience. PMID- 29454390 TI - Promoting public access to clinical trial protocols: challenges and recommendations. AB - BACKGROUND: Recognizing the value of promoting public access to clinical trial protocols, Trials pioneered the way for their publication over a decade ago. However, despite major advances in the public accessibility of information about trial methods and results, protocol sharing remains relatively rare. MAIN BODY: Protocol sharing facilitates the critical appraisal of clinical trials and helps to identify and deter the selective reporting of outcomes and analyses. Challenges to the routine availability of high quality trial protocols include the gaps in incentives and adherence mechanisms, limited venues for sharing the original and final protocol versions, and the need for mechanisms to ensure transparent and complete protocol content. CONCLUSIONS: We propose recommendations for addressing key challenges to protocol sharing in order to promote routine public access to protocols for the benefit of patients and other users of evidence from clinical trials. PMID- 29454392 TI - Soft robotic devices for hand rehabilitation and assistance: a narrative review. AB - INTRODUCTION: The debilitating effects on hand function from a number of a neurologic disorders has given rise to the development of rehabilitative robotic devices aimed at restoring hand function in these patients. To combat the shortcomings of previous traditional robotics, soft robotics are rapidly emerging as an alternative due to their inherent safety, less complex designs, and increased potential for portability and efficacy. While several groups have begun designing devices, there are few devices that have progressed enough to provide clinical evidence of their design's therapeutic abilities. Therefore, a global review of devices that have been previously attempted could facilitate the development of new and improved devices in the next step towards obtaining clinical proof of the rehabilitative effects of soft robotics in hand dysfunction. METHODS: A literature search was performed in SportDiscus, Pubmed, Scopus, and Web of Science for articles related to the design of soft robotic devices for hand rehabilitation. A framework of the key design elements of the devices was developed to ease the comparison of the various approaches to building them. This framework includes an analysis of the trends in portability, safety features, user intent detection methods, actuation systems, total DOF, number of independent actuators, device weight, evaluation metrics, and modes of rehabilitation. RESULTS: In this study, a total of 62 articles representing 44 unique devices were identified and summarized according to the framework we developed to compare different design aspects. By far, the most common type of device was that which used a pneumatic actuator to guide finger flexion/extension. However, the remainder of our framework elements yielded more heterogeneous results. Consequently, those results are summarized and the advantages and disadvantages of many design choices as well as their rationales were highlighted. CONCLUSION: The past 3 years has seen a rapid increase in the development of soft robotic devices for hand rehabilitative applications. These mostly preclinical research prototypes display a wide range of technical solutions which have been highlighted in the framework developed in this analysis. More work needs to be done in actuator design, safety, and implementation in order for these devices to progress to clinical trials. It is our goal that this review will guide future developers through the various design considerations in order to develop better devices for patients with hand impairments. PMID- 29454391 TI - Type 1 diabetes susceptibility alleles are associated with distinct alterations in the gut microbiota. AB - BACKGROUND: Dysbiosis of the gut microbiota has been implicated in the pathogenesis of many autoimmune conditions including type 1 diabetes (T1D). It is unknown whether changes in the gut microbiota observed in T1D are due to environmental drivers, genetic risk factors, or both. Here, we have performed an analysis of associations between the gut microbiota and T1D genetic risk using the non-obese diabetic (NOD) mouse model of T1D and the TwinsUK cohort. RESULTS: Through the analysis of five separate colonies of T1D susceptible NOD mice, we identified similarities in NOD microbiome that were independent of animal facility. Introduction of disease protective alleles at the Idd3 and Idd5 loci (IL2, Ctla4, Slc11a1, and Acadl) resulted in significant alterations in the NOD microbiome. Disease-protected strains exhibited a restoration of immune regulatory pathways within the gut which could also be reestablished using IL-2 therapy. Increased T1D disease risk from IL-2 pathway loci in the TwinsUK cohort of human subjects resulted in some similar microbiota changes to those observed in the NOD mouse. CONCLUSIONS: These findings demonstrate for the first time that type 1 diabetes-associated genetic variants that restore immune tolerance to islet antigens also result in functional changes in the gut immune system and resultant changes in the microbiota. PMID- 29454393 TI - Health professionals' perceptions about their clinical performance and the influence of audit and feedback on their intentions to improve practice: a theory based study in Dutch intensive care units. AB - BACKGROUND: Audit and feedback aims to guide health professionals in improving aspects of their practice that need it most. Evidence suggests that feedback fails to increase accuracy of professional perceptions about clinical performance, which likely reduces audit and feedback effectiveness. This study investigates health professionals' perceptions about their clinical performance and the influence of feedback on their intentions to change practice. METHODS: We conducted an online laboratory experiment guided by Control Theory with 72 intensive care professionals from 21 units. For each of four new pain management indicators, we collected professionals' perceptions about their clinical performance; peer performance; targets; and improvement intentions before and after receiving first-time feedback. An electronic audit and feedback dashboard provided ICU's own performance, median and top 10% peer performance, and improvement recommendations. The experiment took place approximately 1 month before units enrolled into a cluster-randomised trial assessing the impact of adding a toolbox with suggested actions and materials to improve intensive care pain management. During the experiment, the toolbox was inaccessible; all participants accessed the same version of the dashboard. RESULTS: We analysed 288 observations. In 53.8%, intensive care professionals overestimated their clinical performance; but in only 13.5%, they underestimated it. On average, performance was overestimated by 22.9% (on a 0-100% scale). Professionals similarly overestimated peer performance, and set targets 20.3% higher than the top performance benchmarks. In 68.4% of cases, intentions to improve practice were consistent with actual gaps in performance, even before professionals had received feedback; which increased to 79.9% after receiving feedback (odds ratio, 2.41; 95% CI, 1.53 to 3.78). However, in 56.3% of cases, professionals still wanted to improve care aspects at which they were already top performers. Alternatively, in 8.3% of cases, they lacked improvement intentions because they did not consider indicators important; did not trust the data; or deemed benchmarks unrealistic. CONCLUSIONS: Audit and feedback helps health professionals to work on aspects for which improvement is recommended. Given the abundance of professionals' prior good improvement intentions, the limited effects typically found by audit and feedback studies are likely predominantly caused by barriers to translation of intentions into actual change in clinical practice.

We present a case of traumatic chylothorax that was successfully treated using lymphangiography through intranodal injection of contrast agent. A 17-year-old girl had chylothorax. It did not improve despite medical treatment. We performed lymphangiography through intranodal injection of an oil contrast agent (Lipiodol). The amount of chylothorax was reduced from 1000 to 120 mL/d, and we could remove the thoracotomy tube. Thereafter, although she had a small amount of pleural effusion, she has not demonstrated aggravation for 19 months. Lymphangiography with oil contrast agent can be one of the options to treat chylothorax. PMID- 29454439 TI - Management of an enormous inferior mesenteric vein aneurysm. AB - Venous aneurysms are rare entities, with mesenteric venous aneurysms among the rarest reported. We present a case of a 66-year-old man with abdominal pain secondary to an enormous 7.8-cm inferior mesenteric vein aneurysm. In addition, he had evidence of other venous abnormalities, including bilateral leg chronic venous insufficiency and a right varicocele. This appears to be the only reported case of an isolated inferior mesenteric vein aneurysm. Adding to its significance, this aneurysm is among the largest of any mesenteric vein aneurysm reported. Given the rupture risk, laparoscopic ligation above the aneurysm was performed.

PMID- 29454441 TI - The hemodynamic effects of pregnancy on the lower extremity venous system. AB - OBJECTIVE: Pregnancy has significant effects on the lower extremity venous system. Increasing venous pressure and blood volume, in combination with reduced flow rates within the deep veins, predisposes pregnant women to both primary and secondary chronic venous insufficiency (CVI). This review article highlights the specific physiologic and hemodynamic changes that occur during pregnancy and examines the nonpharmacologic, pharmacologic, and invasive interventions that are appropriate for both prophylaxis and treatment of CVI and venous thromboembolism (VTE). METHODS: This study is a review article of the key literature related to VTE and CVI in pregnancy. RESULTS: Significant hemodynamic changes occur in the lower extremities during pregnancy. Although well documented and essential to fetal development, these changes can have a negative impact on the maternal lower extremity venous circulation. Consequences of pregnancy can result in venous disease only during pregnancy or, particularly in the multiparous patient, can progress to CVI. An abundance of literature and guidelines exist for the management of VTE during pregnancy; however, the quality and extent of literature based around the management of primary CVI during pregnancy are modest at best. CONCLUSIONS: The physiologic changes throughout the arterial and venous systems during pregnancy are well documented. However, there is a paucity of data available to construct guidelines for care, particularly in the pregnant patient with symptomatic superficial venous insufficiency. Further investigation in the form of prospective randomized trials is required to establish appropriate guidelines for treatment. PMID- 29454442 TI - Site of service in the Quality Payment Program.

PMID- 29454444 TI - Minimally invasive pancreatoduodenectomy: is the incidence of clinically relevant postoperative pancreatic fistula comparable to that after open pancreatoduodenectomy? AB - BACKGROUND: Studies evaluating the efficacy of minimally invasive approaches to pancreatoduodenectomy (MIS-PD) compared to open pancreatioduodenectomy (OPD) have been limited by selection bias and mixed outcomes. METHODS: ACS-NSQIP 2014-2015 pancreas procedure-targeted data were used to identify patients undergoing PD. Intention-to-treat analysis was performed. RESULTS: Of 7907 PD patients, 1277 (16%) underwent MIS-PD: 776 (61%) robotic or laparoscopic PD, 304 (24%) hybrid, and 197 (15%) unplanned conversions. There were no differences in demographics or comorbidities. Patients undergoing MIS-PD were less likely to have pancreatic ductal adenocarcinoma (30.9% vs 53.9%, P < 0.01) and less likely to have a dilated pancreatic duct (21.8% vs 46.7%, P < 0.01). 30-day morbidity was less for MIS-PD (63.6% vs 76.9%, P < 0.01), due to decreased delayed gastric emptying DGE) in the MIS-PD group (8.6% vs 15.5%, P < 0.01). 30-day mortality, length-of-stay, and readmissions were not significantly different. Patients undergoing MIS-PD had greater rates of CR-POPF (15.3% vs 13.0%, P = 0.03). On adjusted multivariable analysis, MIS-PD was not associated with CR-POPF (OR 1.05, 95% CI 0.87-1.26) but was associated with decreased DGE (OR 0.57, 95% CI 0.46-0.71). CONCLUSION: MIS-PD has comparable short-term outcomes to open PD. While CR-POPF rates are greater for MIS-PD, this increased risk appears related to case-selection bias and not inherent to the MIS-approach.

AB - BACKGROUND: Despite supporting scientific evidence, community water fluoridation (CWF) often fails in public referenda. To understand why, the authors quantitatively analyzed text from news media coverage of CWF referenda. METHODS: The authors analyzed text from 234 articles covering 11 CWF referenda conducted in 3 US cities from 1956 through 2013. The authors used cluster analysis to identify each article's core rhetoric and classified it according to sentiment and tone. The authors used multilevel count regression models to measure the use of positive and negative words regarding CWF. RESULTS: Media coverage more closely resembled core rhetoric used by fluoridation opponents than the rhetoric used by fluoridation proponents. Despite the scientific evidence, the media reports were balanced in tone and sentiment for and against CWF. However, in articles emphasizing children, greater negative sentiment was associated with CWF rejection. CONCLUSIONS: Media coverage depicted an artificial balance of evidence and tone in favor of and against CWF. The focus on children was associated with more negative tone in cities where voters rejected CWF.

AB - Cationic lipids have become known as one of the most versatile tools for the delivery of DNA, RNA and many other therapeutic molecules, and are especially attractive because they can be easily designed, synthesized and characterized. Most of cationic lipids share the common structure of cationic head groups and hydrophobic portions with linker bonds between both domains. The linker bond is an important determinant of the chemical stability and biodegradability of cationic lipid, and further governs its transfection efficiency and cytotoxicity. Based on the structures of linker bonds, they can be grouped into many types, such as ether, ester, amide, carbamate, disulfide, urea, acylhydrazone, phosphate, and other unusual types (carnitine, vinyl ether, ketal, glutamic acid, aspartic acid, malonic acid diamide and dihydroxybenzene). This review summarizes some research results concerning the nature (such as the structure and orientation of linker groups) and density (such as the spacing and the number of linker groups) of linker bond for improving the chemical stability, biodegradability, transfection efficiency and cytotoxicity of cationic lipid to overcome the critical barriers of in vitro and in vivo transfection.

AB - With the advent from the laboratory bench to patient bedside in last five decades, vesicular systems have now come to be widely accepted as pragmatic means for controlled delivery of drugs. Their success stories include those of liposomes, niosomes and even the lately developed ethosomes and transferosomes. Pharmacosomes, which, as delivery systems offer numerous advantages and have been widely researched, however, remain largely unacknowledged as a successful delivery system. Though a large number of drugs have been derivatized and formulated into self-assembled vesicular systems, the term pharmacosomes has not been widely used while reporting them. Therefore, their relative obscurity may be attributed to the non-usage of the nomenclature of pharmacosomes by the researchers working in the area. We present a review on the scenario that lead to origin of these bio-inspired vesicles composed of self-assembling amphiphilic molecules. Various drugs that have been formulated into pharmacosomes, their characterization techniques, their properties relative to those of other vesicular delivery systems, and the success achieved so far are also discussed. PMID- 29454465 TI - Fatigue as a mediator of the relationship between quality of life and mental health problems in hospital nurses. AB - The aims of this study were to investigate the relationships among quality of life (QoL), mental health problems and fatigue among hospital nurses, and to test whether fatigue and its multiple dimensions would mediate the effect of QoL on mental health problems. Data were collected using questionnaires (including the World Health Organization Quality of Life-BREF [WHOQOL-BREF], General Health Questionnaire [GHQ-12] and Multidimensional Fatigue Inventory [MFI-20] for evaluation of QoL, mental health problems and fatigue, respectively) from 990 Iranian hospital nurses, and analysed by generalized structural equation modelling (GSEM). The results indicated that QoL, mental health problems and fatigue were interrelated, and supported the direct and indirect (through fatigue) effects of QoL on mental health problems. All domains of the WHOQOL BREF, and particularly physical (sleep problems), psychological (negative feelings) and environmental health (leisure activities) domains, were strongly related to the mental health status of the studied nurses. Fatigue and its multiple dimensions partially mediated the relationship between QoL and mental health problems. The results highlighted the importance of physical, psychological and environmental aspects of QoL and suggested the need for potential interventions to improve fatigue (particularly physical fatigue along with mental fatigue) and consequently mental health status of this working population. The findings have possible implications for nurses' health and patient safety outcomes.

AB - INTRODUCTION: Dermoid cysts of central nervous system are very rare. The usual clinical presentation is dominated by intracranial hypertension, epilepsy and cranial palsy. The revelation mode could be recurrent aseptic meningitis. AIM: The aim of this case report is to consider the dermoid cyst as regards the differential diagnosis in children treated for recurrent aseptic meningitis to avoid misdiagnosis and ice qui a oriente le diagnostic a une meningitnadequate treatment. METHODS: Two children were admitted in the pediatric department for recurrent aseptic meningitis. The MRI confirmed the presence of a posterior fossa dermoid cyst. RESULTS: Loss of meningitis after microsurgical resection. CONCLUSION: The diagnosis of dermoid cyst is performed and reconsidered at an early stage in aseptic meningitis in order to establish an adequate therapy, which is surgery. PMID- 29454467 TI - Microvascular decompression for hemifacial spasm: Outcome on spasm and complications. A review. AB - Over the last decades microvascular decompression (MVD) has been established as the curative treatment of the primary Hemifacial Spasm (HFS), proven to be linked in almost all cases to a neurovascular compression of the facial nerve. Because the disease is not life-threatening and MVD not totally innocuous, efficacy and safety have to be weighted before decision taken of indicating surgery. The authors have been charged by the French Speaking Society of Neurosurgery to conduct a detailed evaluation of the probability of relief of the spasm that MVD is able to obtain, together with its potential complications. For the review, the authors have gone through the reports available from the Pubmed system. Eighty two publications have been read and analysed, totalizing more than 10,000 operated cases. In most series, the percentage of patients with total relief ranged between 85% and 90%. Relief was obtained after a certain delay in as many as in 33%+/-8% of the patients in many series. For those, delay lasted around one year in 12% of them. When effect of MVD was considered achieved, relief remained permanent in all but 1%-2% of the long-term followed patients. As regards to complications, risk of permanent cranial nerve deficit was evaluated at 1%-2% for facial palsy, 2%-3% for non-functional hearing loss, 0.5%-1% for lower cranial nerve dysfunction. Risk of stroke was at 0.1% and mortality at 0.1%. CSF leakage and related complications could be reduced at less than 2% in most series provided careful closing techniques be applied. Complications were at a higher rate in repeated MVD. MVD is an effective curative method for almost all the patients affected with primary HFS. Because MVD for HFS is functional surgery, scrupulous consideration of its potential risks, together with the ways to avoid complications are of paramount importance. When MVD is estimated to have failed, it is wise to wait one year before considering to repeat surgery, as number of patients may benefit from delayed effect. This is the more so as important as repeated surgery entails a higher rate of complications. PMID- 29454468 TI - Systematic review, meta-analysis, and a high-volume center experience supporting the new role of mural nodules proposed by the updated 2017 international guidelines on IPMN of the pancreas. AB - BACKGROUND: Mural nodules (MNs) have a predominant role in the 2016 revision of the international guidelines on intraductal papillary mucinous neoplasms (IPMN) of the pancreas. The aim of this study was to evaluate MNs as predictors of invasive cancer (iCa) or high-grade dysplasia (HGD) in IPMNs and to investigate the role of MN size in risk prediction. METHODS: A PRISMA-compliant systematic review of the literature and meta-analysis on selected studies were conducted. The random effect model was adopted, and the pooled SMD (standardized mean difference) obtained. The surgical series of IPMNs at a single high-volume institution was reviewed. RESULTS: This review included 70 studies and 2297 resected IPMNs. MNs have a positive predictive value for malignancy of 62.2%. The meta-analysis suggested that MN size has a considerable effect on predicting IPMNs with both iCa or HGD with a mean SMD of 0.79. All studies included in the meta-analysis used contrast-enhanced endosonography (CE-EUS) to assess MNs. Due to the heterogeneity of the proposed thresholds, no reliable MN size cut-off was identified. Of 317 IPMNs resected at our institution, 102 (32.1%) had a preoperative diagnosis of MN. Multivariate analysis showed that MN is the only independent predictor of iCa and HGD for all types of IPMNs. CONCLUSION: MNs are reliable predictors of iCa and HGD in IPMNs as proposed by the 2016 IAP guidelines. CE-EUS seems to be the best tool for characterizing size and has the best accuracy for predicting malignancy. Further studies should determine potential MN dimensional cut-offs. PMID- 29454469 TI - Use of a phoneme monitoring task to examine lexical access in adults who do and do not stutter. AB - Previous work has postulated that a deficit in lexicalization may be an underlying cause of a stuttering disorder (Prins, Main, & Wampler, 1997; Wingate, 1988). This study investigates the time course of lexicalization of nouns and verbs in adults who stutter. A generalized phoneme monitoring (PM) paradigm was used. Adults who stutter (AWS) and typically-fluent peers both showed an expected effect of word class (verbs yielded slower and less accurate monitoring than nouns), as well as phoneme position (word medial/final phonemes yielded slower and less accurate monitoring than word initial phonemes). However, AWS had considerably more difficulty when targets to be monitored were embedded in the medial position. A negative correlation between speed and accuracy was found in typically fluent adults, but not in AWS. AWS also scored nonsignificantly more poorly on an experimental language task. Because of the additional difficulty noted in AWS with word-medial targets, our results provide evidence of phonological encoding differences between the two groups. Expanded use of the PM paradigm is recommended for the exploration of additional aspects of language processing in people who stutter. PMID- 29454470 TI - Intracerebral electroencephalography in targeting anterior thalamic nucleus for deep brain stimulation in refractory epilepsy. AB - BACKGROUND: Results of DBS of ATN in refractory epilepsy depend on accuracy of the electrode's location. We searched for characteristic intraoperative, intracerebral EEG recording pattern from anterior thalamic nuclei (ATNs) as a biological marker for verifying the electrode's position. METHODS: There were six patients with refractory epilepsy scheduled for deep brain stimulation (DBS) procedure. At surgery, to map the target, we recorded EEG from each lead of DBS electrodes. One patient underwent a 24 hours EEG with continuous recording from both ATNs before internalization of stimulator units. RESULTS: In all patients we recorded spontaneous bioelectric activity of ATNs. The pattern of the recording from the ATN was similar in all cases. In the one patient where 24-hour recording was done with simultaneous scalp EEG, a complex partial seizure was captured. CONCLUSION: This is the first report of using DBS electrode for intraoperative EEG recordings from the ATN in patients with refractory epilepsy. Since we managed to find the characteristic pattern of bioelectric activity of ATN, this technique seems to be a promising method for targeting this structure during the operation.

AB - Chronic myeloid leukemia (CML) is a myeloproliferative neoplasm, the incidence of which increases with age. Tyrosine kinase inhibitors (TKIs) are the mainstay of CML treatment, including imatinib, nilotinib, dasatinib, bosutinib, and ponatinib. Beyond matching patient disease profiles with TKI specificity, differences in the efficacy and toxicity profiles and a patient's comorbid risk factors should be considered when selecting the most appropriate agent. Our objectives are to review the incidence and severity of cardiovascular, metabolic, and pulmonary disorders associated with these TKIs, highlighting differences in adverse event profiles, suggested risk-mitigation strategies, and guidance for TKI selection in different settings. Patients receiving TKI agents for CML should be monitored for signs and symptoms of toxicity throughout therapy. Preemptive assessment, early toxicity recognition, and prompt management of cardiovascular, metabolic, and pulmonary toxicities can minimize treatment-limiting complications and improve outcomes in patients with CML. PMID- 29454475 TI - Does childhood neglect contribute to violent behavior in adulthood? A review of possible links. AB - Child neglect, whether intentional or unintentional on the part of caregivers, has serious and far-reaching negative consequences for children. Neglect is the most prevalent form of child maltreatment and has been associated with impaired cognitive development, changes in brain structure and nervous systems, behavioral and personality disorders and poor academic performance. However, the role of child neglect, and subtypes of neglect, in the development of adult violent behavior is not well understood. The "cycle of violence" hypothesis, which predicts that individuals exposed to child physical abuse are more likely to be physically violent in adulthood, is well supported by the literature. However, a growing number of studies suggests that child neglect may be equally predictive, or more predictive, of adult violent behavior than child physical abuse. The present review considers a range of studies that investigate aspects of this relationship, and identifies key patterns and trends that have emerged from these investigations. Methodological issues and limitations of the existing literature are also identified and new research directions suggested. This review also considers studies that support the possibility of protective factors against the development of adult violent behavior in victims of child neglect. PMID- 29454476 TI - Frequency of Electrocardiographic Abnormalities in Patients With Psoriasis. AB - Psoriasis is a chronic inflammatory disease associated with cardiovascular disease, for example, myocardial infarction, stroke, cardiovascular death, and arrhythmias. The resting electrocardiogram may carry prognostic information, but limited evidence is available of electrocardiographic findings in subjects with psoriasis. The electrocardiographic results were compared between 1,131 subjects with self-reported psoriasis and 18,397 controls participating in the Danish General Suburban Population Study (GESUS). The mean heart rate was marginally increased in patients with psoriasis (66 +/- 11 vs 65 +/- 11 beats/min, p = 0.007), but not after adjustment for smoking and body mass index. All other examined electrocardiographic variables, including QT interval corrected for heart rate with the Fridericia formula, PR interval, QRS duration, R axis, P-wave duration in lead V1, P-terminal force, J point elevation in lead V1, electrocardiographic criteria for left ventricular hypertrophy, electrocardiographic signs of previous myocardial infarction, and premature ventricular or supraventricular complexes, respectively, were comparable between the 2 groups. In conclusion, psoriasis was associated with a marginal increase in resting heart rate, which was driven by smoking and increased body mass index. All other examined electrocardiographic variables were similar between the 2 groups. The results suggest that psoriasis per se is not associated with significant abnormalities of the electrocardiogram. PMID- 29454477 TI - Effect of Elevated C-Reactive Protein Level at Discharge on Long-Term Outcome in Patients Hospitalized for Acute Heart Failure. AB - In the acute heart failure (AHF) setting, the usefulness of C-reactive protein (CRP) at admission as a risk marker is challenged by the possible confounding effect of an acute-phase response. We thus evaluated the relation of CRP level at discharge (i.e., after stabilization of AHF) with subsequent postdischarge outcome in patients hospitalized for AHF. The acute decompensated heart failure syndromes study prospectively registered 4,269 hospitalized AHF patients with data on CRP levels at discharge. The median CRP level was 3.1 mg/L (interquartile range 1.1 to 9.5 mg/L). Within 120 days after discharge, only CRP levels in the fourth quartile (>=9.6 mg/L) were independently associated with higher all-cause mortality (adjusted hazard ratio [HR], 1.68) according to multivariable models with first-quartile (<=1.1 mg/L) as the reference. However, the HR for CRP levels in the fourth quartile decreased markedly with time, and CRP levels in the second (1.2 to 3.1 mg/L) and third (3.2 to 9.5 mg/L) quartiles were independently associated with poorer survival after the 120-day follow-up period (adjusted HR, 1.41 and 1.63, respectively). In addition, only CRP levels in the third quartile were independently associated with the composite end point of all-cause death and readmission for AHF after the 120 days of long-term follow-up (adjusted HR, 1.31). In conclusion, our results suggest that a modestly elevated CRP level (approximately 3 to 10 mg/L) at discharge had unique long-term prognostic implications in hospitalized patients with AHF. PMID- 29454478 TI - Usefulness of Integrating Heart Failure Risk Factors Into Impairment of Global Longitudinal Strain to Predict Anthracycline-Related Cardiac Dysfunction. AB - The prediction of cancer therapeutics-related cardiac dysfunction (CTRCD) is an essential aspect of care for individuals who receive potentially cardiotoxic oncologic treatments. Certain clinical risk factors have been described for incident CTRCD, and measurement of left ventricular (LV) longitudinal strain by speckle tracking 2-dimensional echocardiography (2DE) is the best-validated myocardial mechanical imaging assessment to detect subtle changes in LV function during cancer treatment. However, the direct integration of clinical and imaging risk factors to predict CTRCD has not yet been extensively examined. This was a retrospective study of 183 women with breast cancer aged 50.9 +/- 10.8 years who received treatment with anthracyclines (doxorubicin dose of 422 +/- 69 mg/m2, with 41.2% of subjects also receiving trastuzumab) and underwent 2DE at clinically determined intervals. CTRCD was diagnosed when LV ejection fraction dropped >=10% to a subnormal (<53%) value by 2DE. Left ventricular global longitudinal strain (LV-GLS) was assessed offline. The risk prediction tool based only on clinical factors previously described by Ezaz et al was applied to our cohort and accurately stratified these subjects into low-, intermediate-, and high-risk groups, with incident CTRCD in 7.4%, 26.9%, and 54.6%, respectively (chi-square = 20.7, p <0.0001). We developed novel multivariate models to predict CTRCD using (1) demographic variables only (c = 0.8674), (2) echocardiographic (peak LV-GLS) variables only (c = 0.8440), or (3) a combination of demographic and echocardiographic variables, with the combined model exhibiting superior receiver-operating characteristics (c = 0.9629). In conclusion, estimation of CTRCD risk should integrate all available data, including both clinical variables and an imaging assessment. PMID- 29454479 TI - The role of antibiotics in acute uncomplicated diverticulitis: A systematic review and meta-analysis. AB - BACKGROUND: Antibiotics use in acute uncomplicated diverticulitis (AUD) remains debated despite recent studies suggesting no difference in outcomes for patients treated without antibiotics. DATA SOURCES: Systematic review and meta-analysis were performed to determine the role of antibiotics in managing AUD. Literature search was conducted using Medline, EMBASE, Scopus, the Cochrane Library, and Web of Science databases from 1946 to June 2017. Eight studies with 2469 patients were included for review. Overall complication rates were not statistically significant between groups (OR 0.72; CI 0.45 to 1.16; P = 0.18), but antibiotic use was associated with a longer length of stay in hospital. Subgroup analysis revealed no difference in readmission rates, treatment failure rates, progression to complicated diverticulitis, or increased need for elective or emergent surgery between study groups. CONCLUSIONS: Antibiotic use in patients with AUD increases length of hospital stay but is not associated with a reduction in overall or individual complication rates. PMID- 29454480 TI - Preoperative pain measures ineffective in outpatient abdominal surgeries. AB - BACKGROUND: The multimodality addition of preoperative gabapentin, acetaminophen, and celecoxib (GAC) and postoperative TENS has been recommended to diminish narcotics. We predict that GAC-TENS implementation will reduce recovery room time, improve pain control, reduce narcotic refills, and demonstrate usefulness of TENS treatment. METHODS: A prospective study compared a control group of patients not utilizing the GAC-TENS protocol during 2015 to patients using the GAC-TENS protocol during 2016. RESULTS: There was less recovery room time in the control group compared to the protocol group. Postoperative day one pain control was similar between the groups. Less refills were noted. TENS unit satisfaction level was rated "very helpful" by 63% of patients. CONCLUSION: The results call into question the efficacy of the American Pain Society recommendations as they increase time in recovery room but do not decrease the quantity of narcotics used in the recovery room, nor do they improve pain satisfaction responses.

AB - BACKGROUND: Prescription opioid medications account for a large number of fatal and non-fatal overdoses. Many opioid prescription medications after surgery go unused, with the potential for diversion and misuse. As surgeons become increasingly aware of their role in opioid misuse, better tools are needed to guide behavior. DATA SOURCES: There has recently been a plethora of research into opioid prescribing after surgery. A review of this literature was performed using a search for manuscripts written in the English language. Our goal was to develop an easily recalled approach to postoperative opioid prescribing. RESULTS: Based on an extensive review of recent literature, we developed the acronym RIGHTT: Risk for adverse event, Insight into pain, Going over pain plan, Halting opioids, Tossing unused opioids and Trouble identification. It is important that surgeons recognize the potential for opioid misuse in their patients. Strategies have been developed to decrease the risk of prescribing opioids. RIGHTT provides a simple acronym for surgeons to integrate best-practice strategies into their management of post-surgical opioids. PMID- 29454486 TI - Discussion.

PMID- 29454487 TI - A cost-utility analysis of transcatheter versus surgical aortic valve replacement for the treatment of aortic stenosis in the population with intermediate surgical risk. AB - OBJECTIVE: Although transcatheter aortic valve implantation has been shown to be noninferior to surgical aortic valve replacement in patients with severe aortic stenosis at intermediate surgical risk, the cost-effectiveness of this strategy in this population is unknown. Our objective was to conduct a cost-utility analysis comparing transcatheter aortic valve implantation with surgical aortic valve replacement in the population with intermediate risk severe aortic stenosis. METHODS: A fully probabilistic Markov model with 30-day cycles was constructed from the Canadian third-party payer's perspective to estimate the difference in cost and effectiveness (measured as quality-adjusted life years) of transcatheter aortic valve implantation versus surgical aortic valve replacement for intermediate-risk patients over a lifetime time horizon, discounted at 1.5% per annum. Clinical trial data from The Placement of Aortic Transcatheter Valve 2 informed the efficacy inputs. Costs (adjusted to 2016 Canadian dollars) were obtained from the Canadian Institute of Health Information and the Ontario Schedule of Benefits. Incremental cost-effectiveness ratios were calculated. RESULTS: In the base-case analysis, total lifetime costs for transcatheter aortic valve implantation were $10,548 higher than surgical aortic valve replacement but added 0.23 quality-adjusted life years, for an incremental cost-effectiveness ratio of $46,083/quality-adjusted life-years gained. Deterministic 1-way analyses showed that the incremental cost-effectiveness ratio was sensitive to rates of complications and cost of the transcatheter aortic valve implantation prosthesis. There was moderate-to-high parameter uncertainty; transcatheter aortic valve implantation was the preferred option in only 52.7% and 55.4% of the simulations at a $50,000 and $100,000 per quality-adjusted life years willingness-to-pay thresholds, respectively. CONCLUSIONS: On the basis of current evidence, transcatheter aortic valve implantation may be cost-effective for the treatment of severe aortic stenosis in patients with intermediate surgical risk. There remains moderate-to-high uncertainty surrounding the base-case incremental cost effectiveness ratio. PMID- 29454488 TI - Robust fault detection for the dynamics of high-speed train with multi-source finite frequency interference. AB - This paper proposes a composite fault detection scheme for the dynamics of high speed train (HST), using an unknown input observer-like (UIO-like) fault detection filter, in the presence of wind gust and operating noises which are modeled as disturbance generated by exogenous system and unknown multi-source disturbance within finite frequency domain. Using system input and system output measurements, the fault detection filter is designed to generate the needed residual signals. In order to decouple disturbance from residual signals without truncating the influence of faults, this paper proposes a method to partition the disturbance into two parts. One subset of the disturbance does not appear in residual dynamics, and the influence of the other subset is constrained by Hinfinity performance index in a finite frequency domain. A set of detection subspaces are defined, and every different fault is assigned to its own detection subspace to guarantee the residual signals are diagonally affected promptly by the faults. Simulations are conducted to demonstrate the effectiveness and merits of the proposed method. PMID- 29454489 TI - Basal cell nevus syndrome (Gorlin syndrome): genetic insights, diagnostic challenges, and unmet milestones. AB - In this article, we present three clinical case reports on Basal Cell Nevus Syndrome (Gorlin Syndrome). Gorlin syndrome is an inherited medical condition with challenges that manifest in multiple body systems and complicate early diagnosis. We examine the epidemiology of the disease and benefits of genetic testing, molecular pathophysiology, and advancement in the molecular-based therapy of Basal Cell Nevus syndrome. The goal of this paper is to shed light on both unmet challenges and advancements in the management of Gorlin syndrome and to provide a new clinical perspective and guidance for future research. Furthermore, the FDA approved Hedgehog pathway inhibitors Vismodegib and Sonidegib designed for advanced basal cell carcinoma have opened a new door for treatment that may ultimately decrease the number of surgeries for a patient with Gorlin syndrome. The role of these agents in syndromic odontogenic keratocyst has not been studied extensively, but one study found that hedgehog pathway inhibitors decrease the size of syndromic odontogenic keratocyst. Ideal surgical treatment that balances low recurrence rates with low impact on one's quality of life for syndromic odontogenic keratocyst is another unanswered question for oral and maxillofacial surgeons. Per survey studies, treatment options practiced for syndromic odontogenic keratocyst range from marsupialization to segmental osteotomy. Future studies performed should take a comprehensive long-term approach with at least three years of follow-up in order to determine the most appropriate treatment.

AB - Acrylamide (AA) is a toxic substance, used to synthesize polymers for industrial and laboratory processes. Also, AA is a food contaminant formed during the high temperature preparation of carbohydrate-rich food. The main subject of this study was to examine effects of subchronic AA treatment on the islets of Langerhans of adult rats. Adult male Wistar rats were orally treated with 25 or 50 mg/kg bw of AA for 3 weeks. Qualitative and quantitative immunohistochemical evaluation of glucagon and insulin expression and stereological analyses of pancreatic alpha and beta cells were performed. Serum insulin and glucose levels were measured. Analysis of glucagon-immunostained sections revealed a dose-dependent increase of intensity of glucagon immunopositive signal, alpha cell surface and numerical densities, volume density of alpha cell nuclei and nucleocytoplasmic ratio in AA treated groups compared to the control. In insulin-immunolabeled pancreatic sections in AA-treated animals was observed decrease of intensity of insulin immunopositive signal, beta cell surface, numerical and volume densities and volume density of beta cell cytoplasm. Serum insulin and glucose concentrations remained unchanged after both AA treatments. The number of islets of Langerhans was not affected by AA treatment. Our results suggest that AA subchronic treatment of adult rats leads to remodeling of islet of Langerhans characterized by alpha cell expansion and beta cell mass reduction.

A new ballast water management risk assessment model was developed to support the implementation of most efficient management measures, which we also present as a flowchart decision support system model. The risk assessment model was tested using data from port baseline surveys where available, and real shipping and ballast water discharges data. The here presented ballast water management risk assessment and possible management options are applicable elsewhere to support and improve complex decision making in the implementation of management requirements according to the ballast water management convention. If needed, the model may easy be adapted to address local specifics in any other region or area. PMID- 29454492 TI - Potential transfer of aquatic organisms via ballast water with a particular focus on harmful and non-indigenous species: A survey from Adriatic ports. AB - Ballast water discharges may cause negative impacts to aquatic ecosystems, human health and economic activities by the introduction of potentially harmful species. Fifty untreated ballast water tanks, ten in each port, were sampled in four Adriatic Italian ports and one Slovenian port. Salinity, temperature and fluorescence were measured on board. Faecal indicator bacteria (FIB), phyto- and zooplankton were qualitatively and quantitatively determined to identify the species assemblage arriving in ballast water. FIB exceeded the convention standard limits in 12% of the sampled tanks. Vibrio cholerae was not detected. The number of viable organisms in the size groups (minimum dimension) <50 and >=10 MUm and >=50 MUm resulted above the abundances required from the Ballast Water Management Convention in 55 and 86% of the samples, respectively. This is not surprising as unmanaged ballast waters were sampled. Some potentially toxic and non-indigenous species were observed in both phyto- and zooplankton assemblages. PMID- 29454493 TI - Updating the recommendations for treatment of tardive syndromes: A systematic review of new evidence and practical treatment algorithm. AB - BACKGROUND: Management of tardive syndromes (TS) is challenging, with only a few evidence-based therapeutic algorithms reported in the American Academy of Neurology (AAN) guideline in 2013. OBJECTIVE: To update the evidence-based recommendations and provide a practical treatment algorithm for management of TS by addressing 5 questions: 1) Is withdrawal of dopamine receptor blocking agents (DRBAs) an effective TS treatment? 2) Does switching from typical to atypical DRBAs reduce TS symptoms? 3) What is the efficacy of pharmacologic agents in treating TS? 4) Do patients with TS benefit from chemodenervation with botulinum toxin? 5) Do patients with TS benefit from surgical therapy? METHODS: Systematic reviews were conducted by searching PsycINFO, Ovid MEDLINE, PubMed, EMBASE, Web of Science and Cochrane for articles published between 2012 and 2017 to identify new evidence published after the 2013 AAN guidelines. Articles were classified according to an AAN 4-tiered evidence-rating scheme. To the extent possible, for each study we attempted to categorize results based on the description of the population enrolled (tardive dyskinesia [TD], tardive dystonia, tardive tremor, etc.). Recommendations were based on the evidence. RESULTS AND RECOMMENDATIONS: New evidence was combined with the existing guideline evidence to inform our recommendations. Deutetrabenazine and valbenazine are established as effective treatments of TD (Level A) and must be recommended as treatment. Clonazepam and Ginkgo biloba probably improve TD (Level B) and should be considered as treatment. Amantadine and tetrabenazine might be considered as TD treatment (Level C). Pallidal deep brain stimulation possibly improves TD and might be considered as a treatment for intractable TD (Level C). There is insufficient evidence to support or refute TS treatment by withdrawing causative agents or switching from typical to atypical DRBA (Level U). PMID- 29454494 TI - Historical perspectives on tardive dyskinesia. AB - Tardive dyskinesia (TD) is a persistent hyperkinetic movement disorder associated with dopamine receptor blocking agents including antipsychotic medications. Although uncertainty and concern about this drug side effect have vacillated since its initial recognition 60 years ago, recent commercial interest in developing effective treatments has rekindled scientific and clinical interest after a protracted period of neglect. Although substantial research has advanced knowledge of the clinical features and epidemiology of TD, many fundamental questions raised by early investigators remain unresolved. In this paper, we review the early clinical reports that led to the acceptance of TD as an iatrogenic disorder and the lingering controversies that emerged thereafter. Continued research on TD as a serious adverse reaction to treatment may not only enhance patient outcomes and recovery efforts but may also provide insights into both the mechanism of action of antipsychotic drugs and the nosology and pathophysiology of idiopathic psychomotor disorders.

In model cyanobacterium Synechocystis sp. PCC 6803 we have heterologously expressed Sphingopyxis sp. USTB-05 microcystinase (MlrA) bearing a 23 amino acid N-terminus secretion peptide from native Synechocystis sp. PCC 6803 PilA (sll1694). The resultant whole cell biocatalyst displayed about 3 times higher activity against microcystin-LR compared to a native MlrA host (Sphingomonas sp. ACM 3962), normalized for optical density. In addition, MlrA activity was found to be almost entirely located in the cyanobacterial cytosolic fraction, despite the presence of the secretion tag, with crude cellular extracts showing MlrA activity comparable to extracts from MlrA expressing E. coli. Furthermore, despite approximately 9.4-fold higher initial MlrA activity of a whole cell E. coli biocatalyst, utilization of a photoautotrophic chassis resulted in prolonged stability of MlrA activity when cultured under semi-natural conditions (using lake water), with the heterologous MlrA biocatalytic activity of the E. coli culture disappearing after 4 days, while the cyanobacterial host displayed activity (3% of initial activity) after 9 days. In addition, the cyanobacterial cell density was maintained over the duration of this experiment while the cell density of the E. coli culture rapidly declined. Lastly, failure to establish a stable cyanobacterial isolate expressing native MlrA (without the N-terminus tag) via the strong cpcB560 promoter draws attention to the use of peptide tags to positively modulate expression of potentially toxic proteins.

AB - This study aimed to elucidate the origin of the widespread nicotine contamination of plant-derived commodities, by conducting field experiments with various herbs and spice plants. By scattering tobacco and cigarette butts on the field and subsequent nicotine analyses of the acceptor plants, we verified that the alkaloid is leached out into the soil and is taken up by the crop plants. This path of contamination pertains even when there is only one cigarette butt per square meter. Even such minor pollution results - at least in the case of basil and peppermint - in considerable high nicotine contaminations, which exceed the maximum residue level by more than 20-fold. The data reported here clearly outline the large practical relevance of this soil-borne contamination path and imply that unthoughtful disposal of cigarette butts in the field by farm workers may be the reason for the widespread occurrence of nicotine contamination in plant-derived commodities. Therefore, such misbehavior needs to be prevented using education and sensitization, and by including this issue into the guidelines of good agricultural practice.

AB - AIMS: To investigate the prevalence of EBF at 3-months postpartum, and the early factors for discontinuation. DESIGN: Observational, retrospective study. LOCATION: Health department of La Ribera, Valencia, Spain. PARTICIPANTS: Newborns between December 2012 to January 2017. METHODS: Pregnant women were interviewed at postpartum and at 3 months regarding variables associated with breastfeeding initiation and continuation, matched with socio-demographic and obstetric neonatal information. MAIN MEASUREMENTS: Prevalence of breastfeeding at discharge and exclusive breastfeeding at 3 months. Reasons for interrupt exclusive breastfeeding. Chi-square determination between qualitative variables. FINDINGS: One thousand three hundred and thirty-eighth women were recruited. EBF at discharge was 68.2% (913) and at 3 months 46.7% (625). EBF duration was 68.7+/ 32.7 days (95% CI: 66.9-71.2). We found statistically significant differences between the type of breastfeeding and the variables, year of study, country of origin and parity (P<0.001, P=0.005 and P=0.05 respectively). Hypogalactia (21.8%) and lower than recommended increase in newborn weight gain (14.9%) were most frequent factors for discontinuation. CONCLUSION: The prevalence of EBF at 3 months is low compared to other similar studies, although we see an upward trend. Belief in hypogalactia influenced the maintenance of exclusive breastfeeding.

PMID- 29454501 TI - Postoperative inflammation and insulin resistance in relation to body composition, adiposity and carbohydrate treatment: A randomised controlled study. AB - BACKGROUND & AIMS: The aims of this study were to identify whether differences in distribution of adipose tissue and skeletal muscle in obese and non-obese individuals contribute to the magnitude of the postoperative inflammatory response and insulin resistance, with and without preoperative treatment with carbohydrate drinks. METHODS: Thirty-two adults (16 obese/16 non-obese) undergoing elective major open abdominal surgery participated in this 2 * 2 factorial, randomised, double-blind, placebo-controlled study. Participants received Nutricia preOp(r) or placebo (800 ml on the night before surgery/400 ml 2-3 h preoperatively) after stratifying for obesity. Insulin sensitivity was measured using the hyperinsulinaemic-euglycaemic clamp preoperatively and on the 1st postoperative day. Vastus lateralis, omental and subcutaneous fat biopsies were taken pre- and postoperatively and analysed after RNA extraction. The primary endpoint was within subject differences in insulin sensitivity. RESULTS: Major abdominal surgery was associated with a 42% reduction in insulin sensitivity from mean(SD) M value of 37.3(11.8) MUmol kg-1 fat free mass (FFM) to 21.7(7.4) MUmol kg-1 FFM, but this was not influenced by obesity or preoperative carbohydrate treatment. Activation of the triggering receptor expressed on myeloid cells (TREM1) pathway was seen in response to surgery in omental fat samples. In postoperative muscle samples, gene expression differences indicated activation of the peroxisome proliferator-activated receptor (PPAR alpha)/retinoid X-receptor (RXR-alpha) pathway in obese but not in non-obese participants. There were no significant changes in gene expression pathways associated with carbohydrate treatment. CONCLUSION: The reduction in insulin sensitivity associated with major abdominal surgery was confirmed but there were no differences associated with preoperative carbohydrates or obesity. PMID- 29454502 TI - Prevalence and side effects of pediatric home tube feeding. AB - BACKGROUND & AIMS: Tube feeding ensures growth, but can have negative effects on health and psychosocial functioning, resulting in health related costs. The aims of this study were to determine the prevalence of pediatric home tube feeding in the Netherlands and to assess the clinical characteristics of tube fed children and side effects of tube feeding. METHODS: The prevalence of pediatric home tube feeding was calculated using data (2010-2014) of both the Medicines and Devices Information Project of the National Health Care Institute, and Statistics Netherlands. Subsequently, a cross-sectional parental online questionnaire was used to obtain data regarding clinical characteristics of tube fed children and side effects of tube feeding. Children aged <=17 years receiving tube feeding >=2 weeks were included. RESULTS: The prevalence of pediatric home tube feeding was 83-92:100,000 children/year. Parents of 279 children (53% boys) completed the questionnaire. Most children (88%) had >=1 medical diagnosis, of which congenital abnormalities (42%), perinatal problems (38%) and neurologic diseases (16%) were most common. They had gastrostomy (60%), nasogastric (33%), or other tube types (7%). Parents of most children (74%) mentioned >=1 side effect due to tube feeding. Vomiting (37%), lack of appetite (29%), and gagging (29%) were reported most frequently. Nasogastric tube placement resolved in negative experiences (94%). CONCLUSIONS: The prevalence of pediatric home tube feeding varies between 83 and 92:100,000 children/year in the Netherlands. These children are characterized by various underlying medical diagnoses. Side effects of tube feeding are frequently reported by parents. Further studies should focus on methods reducing side effects. PMID- 29454503 TI - A mechanistic look at sacubitril/valsartan action. Unravelling magician's secrets. PMID- 29454504 TI - The Radiobiology of Proton Therapy: Challenges and Opportunities Around Relative Biological Effectiveness. AB - With the current UK expansion of proton therapy there is a great opportunity for clinical oncologists to develop a translational interest in the associated scientific base and clinical results. In particular, the underpinning controversy regarding the conversion of photon dose to proton dose by the relative biological effectiveness (RBE) must be understood, including its important implications. At the present time, the proton prescribed dose includes an RBE of 1.1 regardless of tissue, tumour and dose fractionation. A body of data has emerged against this pragmatic approach, including a critique of the existing evidence base, due to choice of dose, use of only acute-reacting in vivo assays, analysis methods and the reference radiations used to determine the RBE. Modelling systems, based on the best available scientific evidence, and which include the clinically useful biological effective dose (BED) concept, have also been developed to estimate proton RBEs for different dose and linear energy transfer (LET) values. The latter reflect ionisation density, which progressively increases along each proton track. Late-reacting tissues, such as the brain, where alpha/beta = 2 Gy, show a higher RBE than 1.1 at a low dose per fraction (1.2-1.8 Gy) at LET values used to cover conventional target volumes and can be much higher. RBE changes with tissue depth seem to vary depending on the method of beam delivery used. To reduce unexpected toxicity, which does occasionally follow proton therapy, a more rational approach to RBE allocation, using a variable RBE that depends on dose per fraction and the tissue and tumour radiobiological characteristics such as alpha/beta, is proposed. PMID- 29454505 TI - Current Management of Intracranial Germ Cell Tumours. AB - Intracranial germ cell tumours (icGCTs) are uncommon tumours occurring in children and young adults. They are usually segregated into germinomas and non germinomatous tumours (NGGCTs) in most classifications. Germinomas are highly curable tumours with multimodality treatment, but NGGCTs are associated with poorer survival outcomes. There are some differences in the approach to the management of icGCTs globally. Current research generally focuses on reducing treatment intensity, particularly the dose and volume of radiotherapy, in order to minimise the risks of late sequelae while maintaining high cure rates in icGCTs. PMID- 29454506 TI - Becoming a Team: The Nature of the Parent-Healthcare Provider Relationship when a Child is Dying in the Pediatric Intensive Care Unit. AB - PURPOSE: To explore bereaved parents' perspectives of parent and staff roles in the pediatric intensive care unit when their child was dying, and their relationships with healthcare staff during this time. DESIGN AND METHODS: Constructivist grounded theory was used to undertake this study. Semi-structured interviewers were conducted with 26 bereaved parents recruited from four Australian pediatric intensive care units. The constant comparative method, coupled with open, focused, and theoretical coding were used for data analysis. RESULTS: Becoming a team explores the changes that occurred to the parent healthcare provider relationship when parents realized their child was dying and attempted to become part of their child's care team. When the focus of care changed from 'life-saving' to 'end-of-life', parents' perspectives and desires of their and the healthcare providers' roles changed. Parents' attempted to reconstruct their roles to match their changing perspectives, which may or may not have been successful, depending on their ability to successfully negotiate these roles with healthcare providers. CONCLUSIONS: Findings offer insights into parental understandings of both the parental and healthcare provider roles for parents of dying children in intensive care, and the ways in which the parent healthcare provider relationships can influence and be influenced by changes to these roles. PRACTICE IMPLICATIONS: Successful parent-healthcare provider relationships require an understanding of the parental and healthcare provider role from the parents' perspective. The meanings of the parental and healthcare provider roles should be explored with parents of dying children, and supported as much as possible to enable the development of a collaborative relationship. PMID- 29454507 TI - Pediatric Early Warning Score Systems, Nurses Perspective - A Focus Group Study. AB - PURPOSE: Pediatric early warning score (PEWS) systems are used to monitor pediatric patients' vital signs and facilitate the treatment of patients at risk of deteriorating. The aim of this study was to gain knowledge about nurses' experiences with PEWS and to highlight factors facilitating and impeding the use of PEWS tools in clinical practice. DESIGN AND METHODS: An exploratory qualitative design was chosen using focus group interviews to gain a deeper understanding of nurses' experiences with PEWS. A total of five focus group interviews were conducted at three hospitals, and a qualitative meaning condensation analysis as described by Kvale and Brinkmann was performed. RESULTS: Seven themes were identified, including i) lack of interdisciplinary awareness, ii) clinical judgment and PEWS-a multi-faceted approach, iii) PEWS supports a professional language, iv) monitoring the patient's - a challenge, v) PEWS helps to visualize the need for escalating care, vi) an inflexible and challenging tool, and vii) supportive tools enhance the nurses' experiences of PEWS positively. CONCLUSIONS: Our findings suggest that attention should be given to nurses' perceptions of how both clinical judgment and PEWS should be seen as essential in providing nurses with information about the patients' conditions. If not, the risk of failing to recognize patients' deteriorating conditions will remain as this can have an impeding influence on nurses' use of PEWS. From the nurses' perspective, medical doctors seemed unaware of their role in using PEWS. PMID- 29454508 TI - The HAS-Choice study: Utilizing the HEART score, an ADP, and shared decision making to decrease admissions in chest pain patients. AB - OBJECTIVE: The HAS-Choice pathway utilizes the HEART Score, an accelerated diagnostic protocol (ADP), and shared decision-making using a visual aid in the evaluation of chest pain patients. We seek to determine if our intervention can improve resource utilization in a community emergency department (ED) setting while maintaining safe patient care. METHODS: This was a single-center prospective cohort study with historical that included ED patients >=21years old presenting with a primary complaint of chest pain in two time periods. The primary outcome was patient disposition. Secondary outcomes focused on 30-day ED bounce back and major adverse cardiac events (MACE). We used multivariate logistic regression to estimate the odds ratio (OR) and its 95% confidence interval (CI). RESULTS: In the pre-implementation period, the unadjusted disposition to inpatient, observation and discharge was 6.5%, 49.1% and 44.4%, respectively, whereas in the post period, the disposition was 4.8%, 41.5% and 53.7%, respectively (chi-square p<0.001). The adjusted odds of a patient being discharged was 40% higher (OR=1.40; 95% CI, 1.30, 1.51; p<0.001) in the post implementation period. The adjusted odds of patient admission was 30% lower (OR=0.70; 95% CI, 0.60, 0.82; p<0.001) in the post-implementation period. The odds of 30-day ED bounce back did not statistically differ between the two periods. MACE rates were <1% in both periods, with a significant decrease in mortality in the post-implementation period. CONCLUSION: Our study suggests that implementation of a shared decision-making tool that integrates an ADP and the HEART score can safely decrease hospital admissions without an increase in MACE. PMID- 29454509 TI - Group C strep mediastinitis. AB - This case is significant to the practice of emergency medicine because it represents the development of an uncommon and potentially fatal mediastinal infection from a commonly encountered and appropriately treated community respiratory pathogen. Most published reports on mediastinitis are those that are status-post cardiothoracic surgery. In our report, we discuss a case of a healthy, young individual who developed this morbid entity from extension of a simple respiratory infection where Group C Streptococcus has been isolated as the causative organism, which to our knowledge has not been previously reported. Further, this report outlines how a community acquired pneumonia progressed to a life threatening illness despite proper initial treatment per local and national guidelines. PMID- 29454510 TI - Beyond thrombosis: Anti-beta2GPI domain 1 antibodies identify late pregnancy morbidity in anti-phospholipid syndrome. AB - Antibodies against beta2 glycoprotein I (anti-beta2GPI) have been identified as the main pathogenic autoantibody subset in anti-phospholipid syndrome (APS); the most relevant epitope is a cryptic and conformation-dependent structure on beta2GPI domain (D) 1. Anti-beta2GPI domain profiling has been investigated in thrombotic APS, leading to the identification of antibodies targeting D1 as the main subpopulation. In contrast, scarce attention has been paid to obstetric APS, hence this study aimed at characterizing the domain reactivity with regards to pregnancy morbidity (PM). To this end, 135 women with persistently positive, medium/high titre anti-beta2GPI IgG, without any associated systemic autoimmune diseases and at least one previous pregnancy were included: 27 asymptomatic carriers; 53 women with obstetric APS; 20 women with thrombotic APS; and 35 women with both thrombotic and obstetric complications. Anti-D1 and anti-D4/5 antibodies were tested using a chemiluminescent immunoassay and a research ELISA assay, respectively (QUANTA Flash(r) beta2GPI Domain 1 IgG and QUANTA Lite(r) beta2GPI D4/5 IgG, Inova Diagnostics). Positivity for anti-D1 antibodies, but not anti-D4/5 antibodies, was differently distributed across the 4 subgroups of patients (p < 0.0001) and significantly correlated with thrombosis (chi2 = 17.28, p < 0.0001) and PM (chi2 = 4.28, p = 0.039). Patients with triple positivity for anti-phospholipid antibodies displayed higher anti-D1 titres and lower anti-D4/5 titres compared to women with one or two positive tests (p < 0.0001 and p = 0.005, respectively). Reactivity against D1 was identified as a predictor for PM (OR 2.4, 95% confidence interval [CI] 1.2-5.0, p = 0.017); in particular, anti-D1 antibodies were predictive of late PM, conveying an odds ratio of 7.3 (95% CI 2.1 25.5, p = 0.022). Positivity for anti-D1 antibodies was not associated with early pregnancy loss. Anti-D4/5 antibodies were not associated with clinical APS manifestations. As a whole, our data suggest that anti-D1 antibodies are significantly associated not only with thrombosis, but also with late PM, while positive anti-D4/5 antibodies are not predictive of thrombosis or PM. PMID- 29454511 TI - Musical deficits and cortical thickness in people with schizophrenia. AB - Investigation of acquired amusia caused by brain damage suggested that cortical lesions of the right hemisphere contributed to musical deficits. We previously reported reduced musical ability in schizophrenia; these deficits were correlated with clinical manifestations such as cognitive dysfunction and negative symptoms. However, the neural substrate underlying the musical disability in schizophrenia remains unclear. We investigated the relationship between musical deficits and cortical thickness in patients with schizophrenia using structural MRI. We recruited 24 patients (13 males; age mean=45.9years old), and 22 controls (14 males, age mean=43.5years old). Musical ability was assessed with the Montreal Battery for Evaluation of Amusia (MBEA), cognitive function with the Brief Assessment of Cognition in Schizophrenia (BACS) and clinical features of illness with the Positive and Negative Syndrome Scale (PANSS). MRI Images were acquired and processed using FreeSurfer. Surface-based analysis showed that thinner cortex in left temporal and inferior frontal region was associated with lower musical ability in schizophrenia. In contrast, in controls thicker cortex in the left supramarginal region was correlated with lower musical ability. These results shed light on the clinical pathology underlying the associations of musical ability, cognitive dysfunction and negative symptoms in patients with schizophrenia. PMID- 29454512 TI - Frontal and temporal cortical volume, white matter tract integrity, and hemispheric asymmetry in schizotypal personality disorder. AB - Abnormalities in temporal and frontal cortical volume, white matter tract integrity, and hemispheric asymmetry have been implicated in schizophrenia spectrum disorders. Schizotypal personality disorder can provide insight into vulnerability and protective factors in these disorders without the confounds associated with chronic psychosis. However, multimodal imaging and asymmetry studies in SPD are sparse. Thirty-seven individuals with SPD and 29 healthy controls (HC) received clinical interviews and 3T magnetic resonance T1-weighted and diffusion tensor imaging scans. Mixed ANOVAs were performed on gray matter volumes of the lateral temporal regions involved in auditory and language processing and dorsolateral prefrontal cortex involved in executive functioning, as well as fractional anisotropy (FA) of prominent white matter tracts that connect frontal and temporal lobes. In the temporal lobe regions, there were no group differences in volume, but SPD had reduced right>left middle temporal gyrus volume asymmetry compared to HC and lacked the right>left asymmetry in the inferior temporal gyrus volume seen in HC. In the frontal regions, there were no differences between groups on volume or asymmetry. In the white matter tracts, SPD had reduced FA in the left sagittal stratum and superior longitudinal fasciculus, and increased right>left asymmetry in sagittal stratum FA compared to HC. In the SPD group, lower left superior longitudinal fasciculus FA was associated with greater severity of disorganization symptoms. Findings suggest that abnormities in structure and asymmetry of temporal regions and frontotemporal white matter tract integrity are implicated in SPD pathology. PMID- 29454513 TI - Outcomes and related factors in a cohort of infants born in Taiwan over a period of five years (2007-2011) with borderline viability. AB - BACKGROUND: Advances in perinatal and neonatal care have increased the survival of extremely preterm infants, but the viability limit is still debated. Here we assess the survival, neonatal morbidity, and neurodevelopmental outcomes at 2 years of age of infants born at 22-26 weeks of gestation in Taiwan between 2007 and 2011. METHODS: This is a prospective longitudinal multicenter cohort study on extremely preterm infants registered in the Taiwan Premature Infant Developmental Collaborative Study Group from 2007 to 2011, including 22 neonatal care centers. We extracted demographic and clinical data of infants born at 22-26 weeks, and obtained growth and developmental outcome data from the follow-up clinic at 24 months of corrected age. Multivariate analyses using a logistic regression model identified factors significantly impacting survival. RESULTS: 647 of the 1098 infants included in the study (58.9%) survived to discharge. Survival rates were 8% (4/50), 25% (27/108), 46.8% (117/250), 67.0% (211/315), and 76.8% (288/375) for infants born at 22, 23, 24, 25, and 26 weeks, respectively. Most survivors (567/647, 87.6%) had major morbidities during hospitalization, and we identified factors that positively and negatively affected survival. 514 (79.4%) patients received follow-up evaluation at 2 years, and 204 (39.7%) of them had neurodevelopmental impairment (NDI) with an incidence of 75%, 65.2%, 49.5%, 39.5%, and 32.8% for infants born at 22, 23, 24, 25, and 26 weeks, respectively. CONCLUSION: Infants born at 22 and 23 weeks have a very low likelihood of surviving with little or no impairment. These findings are valuable for parental counseling and perinatal care decisions. PMID- 29454514 TI - Phase 2 study evaluating intermittent and continuous linsitinib and weekly paclitaxel in patients with recurrent platinum resistant ovarian epithelial cancer. AB - BACKGROUND: Linsitinib, an oral, dual inhibitor of insulin-like growth factor-1 receptor and insulin receptor, in combination with weekly paclitaxel, may improve clinical outcomes compared with paclitaxel alone in patients with refractory or platinum-resistant ovarian cancer. PATIENTS AND METHODS: This open-label phase 1/2 clinical trial (NCT00889382) randomized patients with refractory or platinum resistant ovarian cancer (1:1:1) to receive either oral intermittent linsitinib (600mg once daily on Days 1-3 per week) combined with paclitaxel (80mg/m2 on Days 1, 8, and 15; Arm A) or continuous linsitinib (150mg twice daily) in combination with paclitaxel (Arm B), or paclitaxel alone (Arm C). Primary endpoint was progression-free survival (PFS); secondary endpoints included overall survival (OS), overall response rate (ORR), disease control rate (DCR), and safety/tolerability. RESULTS: A total of 152 women were randomized to treatment (n=51 Arm A; n=51 Arm B, n=50 Arm C). In combination with paclitaxel, neither intermittent linsitinib (median PFS 2.8months; 95% confidence interval [CI]:2.5 4.4) nor continuous linsitinib (median PFS 4.2months; 95% CI:2.8-5.1) improved PFS over weekly paclitaxel alone (median PFS 5.6months; 95% CI:3.2-6.9). No improvement in ORR, DCR, or OS in either linsitinib dosing schedule was observed compared with paclitaxel alone. Adverse event (AE) rates, including all-grade and grade 3/4 treatment-related AEs, and treatment-related AEs leading to discontinuation, were higher among patients receiving intermittent linsitinib compared with the other treatment arms. CONCLUSION: Addition of intermittent or continuous linsitinib with paclitaxel did not improve outcomes in patients with platinum-resistant/refractory ovarian cancer compared with paclitaxel alone. PMID- 29454515 TI - Quantitative profiling reveals minor changes of T cell receptor repertoire in response to subunit inactivated influenza vaccine. AB - Vaccination against influenza is widely used to protect against seasonal flu epidemic although its effectiveness is debated. Here we performed deep quantitative T cell receptor repertoire profiling in peripheral blood of a healthy volunteer in response to trivalent subunit influenza vaccine. We did not observe significant rebuilding of peripheral blood T cell receptors composition in response to vaccination. However, we found several clonotypes in memory T cell fraction that were undetectable before the vaccination and had a maximum concentration at day 45 after vaccine administration. These cells were found in lower concentration in the course of repertoire monitoring for two years period. Our observation suggests a potential for recruitment of only a limited number of new T cells after each seasonal influenza vaccination. PMID- 29454516 TI - Immunity against measles, mumps, rubella, varicella, diphtheria, tetanus, polio, hepatitis A and hepatitis B among adult asylum seekers in the Netherlands, 2016. AB - Asylum seekers are a vulnerable population for contracting infectious diseases. Outbreaks occur among children and adults. In the Netherlands, asylum seeker children are offered vaccination according to the National Immunization Program. Little is known about protection against vaccine-preventable diseases (VPD) in adult asylum seekers. In this 2016 study, we assessed the immunity of adult asylum seekers against nine VPD to identify groups that might benefit from additional vaccinations. We invited asylum seekers from Syria, Iran, Iraq, Afghanistan, Eritrea and Ethiopia to participate in a serosurvey. Participants provided informed consent and a blood sample, and completed a questionnaire. We measured prevalence of protective antibodies to measles, mumps, rubella, varicella, diphtheria, tetanus, polio type 1-3 and hepatitis A and B, stratified them by country of origin and age groups. The median age of the 622 participants was 28 years (interquartile range: 23-35), 81% were male and 48% originated from Syria. Overall, seroprotection was 88% for measles (range between countries: 83 93%), 91% for mumps (81-95%), 94% for rubella (84-98%), 96% for varicella (92 98%), 82% for diphtheria (65-88%), 98% for tetanus (86-100%), 91% (88-94%) for polio type 1, 95% (90-98%) for polio type 2, 82% (76-86%) for polio type 3, 84% (54-100%) for hepatitis A and 27% for hepatitis B (anti-HBs; 8-42%). Our results indicate insufficient protection against certain VPD in some subgroups. For all countries except Eritrea, measles seroprotection was below the 95% threshold required for elimination. Measles seroprevalence was lowest among adults younger than 25 years. In comparison, seroprevalence in the Dutch general population was 96% in 2006/07. The results of this study can help prioritizing vaccination of susceptible subgroups of adult asylum seekers, in general and in outbreak situations. PMID- 29454517 TI - Intradermal immunization with inactivated swine influenza virus and adjuvant polydi(sodium carboxylatoethylphenoxy)phosphazene (PCEP) induced humoral and cell mediated immunity and reduced lung viral titres in pigs. AB - Swine influenza virus is endemic worldwide and it is responsible for significant economic losses to the swine industry. A vaccine that stimulates a rapid and long lasting protective immune response to prevent this infection is highly sought. Poly[di(sodium carboxylatoethylphenoxy)-phosphazene (PCEP) has demonstrated adjuvant activity when formulated as part of multiple vaccines in mice and pigs. In this study we examined the magnitude and type of immune response induced in pigs vaccinated via the intramuscular or intradermal routes with inactivated swine influenza virus (SIV) H1N1 vaccine formulated with PCEP. Intradermal administration of PCEP-adjuvanted inactivated SIV vaccine stimulated significant anti-SIV antibody titres, increased neutralizing antibodies, and significantly reduced lung virus load with limited reduction of gross lung lesions after challenge with virulent H1N1 relative to control animals. These results indicate that PCEP may be effective as a vaccine adjuvant against swine influenza viruses in pigs and should be considered a potential candidate adjuvant for future swine intradermal influenza vaccines. PMID- 29454518 TI - Use of a new global indicator for vaccine safety surveillance and trends in adverse events following immunization reporting 2000-2015. AB - Reporting of adverse events following immunization (AEFI) is a key component for functional vaccine safety monitoring system. The aim of our study is to document trends in the AEFI reporting ratio globally and across the six World Health Organization (WHO) regions. We describe the number of AEFI reports communicated each year through the World Health Organization/United Nations Children's Fund Joint Reporting Form on Immunization from 2000 to 2015. The AEFI reporting ratios (annual AEFI reports per 100,000 surviving infants) were calculated to identify WHO countries (n = 191 in 2000 and n = 194 by 2015) that met a minimal reporting ratio of 10, a target set by the Global Vaccine Action Plan for vaccine safety monitoring as a proxy measure for a functional AEFI reporting system. The number of countries reporting any AEFI fluctuated over time but with progress from 32 (17%) in 2000 to 124 (64%) in 2015. In 2015, the global average AEFI reporting ratio was 549 AEFI reports per 100,000 surviving infants. The number of countries with AEFI reporting ratios greater than 10 increased from 8 (4%) in 2000 to 81 (42%) in 2015. In 2015, 60% of countries in the WHO Region of the Americas reported at least 10 AEFI per 100,000 surviving infants, followed by 55% in European Region, 43% in Eastern Mediterranean Region, 33% in Western Pacific Region, 27% in South-East Asia Region and 21% in African Region. Overall, AEFI reporting has increased over the past sixteen years worldwide, but requires strengthening in a majority of low- and middle- income countries. The AEFI reporting ratio is useful for benchmarking and following trends over time; but does not provide information on the quality of the reporting system and does not guarantee capacity to detect and manage a vaccine safety problem at a national level. Additional efforts are required to ensure and improve data quality, AEFI reporting and surveillance of immunization safety in every country. PMID- 29454520 TI - Ad hominem attacks on vaccine safety researchers. PMID- 29454519 TI - High resolution age-structured mapping of childhood vaccination coverage in low and middle income countries. AB - BACKGROUND: The expansion of childhood vaccination programs in low and middle income countries has been a substantial public health success story. Indicators of the performance of intervention programmes such as coverage levels and numbers covered are typically measured through national statistics or at the scale of large regions due to survey design, administrative convenience or operational limitations. These mask heterogeneities and 'coldspots' of low coverage that may allow diseases to persist, even if overall coverage is high. Hence, to decrease inequities and accelerate progress towards disease elimination goals, fine-scale variation in coverage should be better characterized. METHODS: Using measles as an example, cluster-level Demographic and Health Surveys (DHS) data were used to map vaccination coverage at 1 km spatial resolution in Cambodia, Mozambique and Nigeria for varying age-group categories of children under five years, using Bayesian geostatistical techniques built on a suite of publicly available geospatial covariates and implemented via Markov Chain Monte Carlo (MCMC) methods. RESULTS: Measles vaccination coverage was found to be strongly predicted by just 4-5 covariates in geostatistical models, with remoteness consistently selected as a key variable. The output 1 * 1 km maps revealed significant heterogeneities within the three countries that were not captured using province level summaries. Integration with population data showed that at the time of the surveys, few districts attained the 80% coverage, that is one component of the WHO Global Vaccine Action Plan 2020 targets. CONCLUSION: The elimination of vaccine-preventable diseases requires a strong evidence base to guide strategies and inform efficient use of limited resources. The approaches outlined here provide a route to moving beyond large area summaries of vaccination coverage that mask epidemiologically-important heterogeneities to detailed maps that capture subnational vulnerabilities. The output datasets are built on open data and methods, and in flexible format that can be aggregated to more operationally relevant administrative unit levels. PMID- 29454521 TI - Hepatitis B vaccination and the putative risk of central demyelinating diseases - A systematic review and meta-analysis. AB - BACKGROUND: The anti-hepatitis B immunization campaigns launched in the early 1990s were a major public health breakthrough and targeted various populations (at-risk adults, newborns, adolescents). However, debate is still active about a possible link between this vaccine and central demyelination. This study provides a pooled estimate of this risk based on a comprehensive review and meta-analysis of all available epidemiologic studies. METHODS: A systematic review was conducted in Medline, Embase, ISI Web of Science and the Cochrane Library from database inception to 10 May 2017. Grey literature was searched and snowballing was also undertaken. Only observational studies including a control group were retained. Primary outcome was multiple sclerosis diagnosed by recognized criteria. Study selection was performed by two independent reviewers with disagreements solved through discussion. This meta-analysis based on crude, adjusted estimates, or risks limited to the 3 months following immunization was performed using a generic inverse variance random-effect model. Heterogeneity was investigated; sensitivity and subgroup analyses were performed when necessary. This study followed the PRISMA statement and the MOOSE reporting guideline (Study protocol registered in PROSPERO: CRD42015020808). FINDINGS: Of the 2804 references reviewed, 13 studies with a control group were analysed. None of the pooled risk estimates for either multiple sclerosis or central demyelination following HB immunization reached statistical significance. When considering adjusted risk ratios, the following non-significant figures were obtained: 1.19 (95%CI: 0.93 - 1.52) and 1.25 (95%CI: 0.97 - 1.62), for multiple sclerosis and central demyelination, respectively. CONCLUSIONS: No evidence of an association between hepatitis B vaccination and central demyelination was found. PMID- 29454522 TI - Genetic and subunit vaccines based on the stem domain of the equine influenza hemagglutinin provide homosubtypic protection against heterologous strains. AB - H3N8 influenza virus strains have been associated with infectious disease in equine populations throughout the world. Although current vaccines for equine influenza stimulate a protective humoral immune response against the surface glycoproteins, disease in vaccinated horses has been frequently reported, probably due to poor induction of cross-reactive antibodies against non-matching strains. This work describes the performance of a recombinant protein vaccine expressed in prokaryotic cells (DeltaHAp) and of a genetic vaccine (DeltaHAe), both based on the conserved stem region of influenza hemagglutinin (HA) derived from A/equine/Argentina/1/93 (H3N8) virus. Sera from mice inoculated with these immunogens in different combinations and regimes presented reactivity in vitro against highly divergent influenza virus strains belonging to phylogenetic groups 1 and 2 (H1 and H3 subtypes, respectively), and conferred robust protection against a lethal challenge with both the homologous equine strain (100%) and the homosubtypic human strain A/Victoria/3/75 (H3N2) (70-100%). Animals vaccinated with the same antigens but challenged with the human strain A/PR/8/34 (H1N1), belonging to the phylogenetic group 1, were not protected (0-33%). Combination of protein and DNA immunogens showed higher reactivity to non-homologous strains than protein alone, although all vaccines were permissive for lung infection.

PMID- 29454525 TI - Radial umbilical dermatofasciolysis to invert the skin following umbilical herniorrhaphy. AB - BACKGROUND: Umbilical hernia is a common congenital anomaly, and can result in the appearance of a protuberant umbilicus. In select cases, inversion of the umbilical skin can be impaired by the presence of thickened dermis or fascial remnants of the umbilical stalk. DESCRIPTION OF OPERATIVE TECHNIQUE: After umbilical herniorrhaphy, the skin is everted over the left index finger and radial partial thickness incisions in the fascia and dermis of the undersurface of the umbilicus. The umbilical skin is then inverted and secured to the fascia. CONCLUSION: This operative technique can allow complete inversion of the umbilical skin creating an aesthetically appealing umbilical hernia repair. PMID- 29454526 TI - Predicting sexual problems in young adults with an anorectal malformation or Hirschsprung disease. AB - AIM: The aim of this study was to examine the prevalence of sexual dysfunction and distress and to assess whether sexual functioning could be predicted by psychosocial factors in childhood and adolescence in patients with an anorectal malformation or Hirschsprung disease. MATERIAL AND METHODS: In 1998 patients completed a psychosocial questionnaire: The Self-Perception profile. To assess the prevalence of sexual distress and sexual functioning in adulthood (2015) the Female Sexual Function Index (FSFI), The Female Sexual Distress Scale (FSDS) and the International Index of Erectile Functioning (IIEF) were used. RESULTS: In total 74 patients returned the questionnaires (26.2%). 36.8% of women reported sexual dysfunction and 45% experienced sexual distress. In our male sample 8.8% reported mild to moderate erectile dysfunction. In females perceived self competence in adolescence was associated with sexual distress (p<.01). In male adolescents associations were found between perceived self-competence in romantic relations (p<.01) and in close friendships (p<.05) and sexual desire in adulthood. CONCLUSION: Pediatric surgeons should be more aware of sexual problems patients may face at older age as a result of their congenital disease and treatment. More standardized care and follow-up are needed. Prognosis study-Level II. PMID- 29454527 TI - WITHDRAWN: Cardiac Calendar 2016-2020. PMID- 29454528 TI - Continuous Infusion versus Intermittent Bolus Injection of Furosemide in Critically Ill Patients: A Systematic Review and Meta-analysis. AB - OBJECTIVE: Fluid overload is a common phenomenon seen in intensive care units (ICUs). However, there is no general consensus on whether continuous or bolus furosemide is safer or more effective in these hemodynamically unstable ICU patients. The aim of this meta-analysis was to examine the clinical outcomes of continuous versus bolus furosemide in a critically ill population in ICUs. DATA SOURCES: MEDLINE, EMBASE, PubMed, and the Cochrane Database of Systematic reviews were searched from their inception until June 2017. REVIEW METHODS: All randomized controlled trials, observational studies, and case-control studies were included. Case reports, case series, nonsystematic reviews, and studies that involved children were excluded. RESULTS: Nine studies (n = 464) were eligible in the data synthesis. Both continuous and bolus furosemide resulted in no difference in all-cause mortality (7 studies; n = 396; I2 = 0%; fixed-effect model [FEM]: odds ratio [OR] 1.15 [95% confidence interval (CI) 0.67-1.96]; p = 0.64). Continuous furosemide was associated with significant greater total urine output (n = 132; I2 = 70%; random-effect model: OR 811.19 [95% CI 99.84 1,522.53]; p = 0.03), but longer length of hospital stay (n = 290; I2 = 40%; FEM: OR 2.84 [95% CI 1.74-3.94]; p < 0.01) in comparison to the bolus group. No statistical significance was found in the changes of creatinine and estimated glomerular filtration rate between both groups. CONCLUSIONS: In this meta analysis, continuous furosemide was associated with greater diuretic effect in total urine output as compared with bolus. Neither had any differences in mortality and changes of renal function tests. However, a large adequately powered randomized clinical trial is required to fill this knowledge gap. PMID- 29454529 TI - Retention prediction in reversed phase high performance liquid chromatography using quantitative structure-retention relationships applied to the Hydrophobic Subtraction Model. AB - Quantitative Structure-Retention Relationships (QSRR) methodology combined with the Hydrophobic Subtraction Model (HSM) have been utilized to accurately predict retention times for a selection of analytes on several different reversed phase liquid chromatography (RPLC) columns. This approach is designed to facilitate early prediction of co-elution of analytes, for example in pharmaceutical drug discovery applications where it is advantageous to predict whether impurities might be co-eluted with the active drug component. The QSRR model utilized VolSurf+ descriptors and a Partial Least Squares regression combined with a Genetic Algorithm (GA-PLS) to predict the solute coefficients in the HSM. It was found that only the hydrophobicity (eta'H) term in the HSM was required to give the accuracy necessary to predict potential co-elution of analytes. Global QSRR models derived from all 148 compounds in the dataset were compared to QSRR models derived using a range of local modelling techniques based on clustering of compounds in the dataset by the structural similarity of compounds (as represented by the Tanimoto similarity index), physico-chemical similarity of compounds (represented by log D), the neutral, acidic, or basic nature of the compound, and the second dominant interaction between analyte and stationary phase after hydrophobicity. The global model showed reasonable prediction accuracy for retention time with errors of 30 s and less for up to 50% of modeled compounds. The local models for Tanimoto, nature of the compound and second dominant interaction approaches all exhibited prediction errors less than 30 s in retention time for nearly 70% of compounds for which models could be derived. Predicted retention times of five representative compounds on nine reversed-phase columns were compared with known experimental retention data for these columns and this comparison showed that the accuracy of the proposed modelling approach is sufficient to reliably predict the retention times of analytes based only on their chemical structures. PMID- 29454530 TI - System dynamics model of taxi management in metropolises: Economic and environmental implications for Beijing. AB - Taxis are an important component of urban passenger transport. Research on the daily dispatching of taxis and the utility of governmental management is important for the improvement of passenger travel, taxi driver income and environmental impacts. However, urban taxi management is a complex and dynamic system that is affected by many factors, and positive/negative feedback relationships and nonlinear interactions exist between each subsystem and variable. Therefore, conventional research methods can hardly depict its characteristics comprehensively. To bridge this gap, this paper develops a system dynamics model of urban taxi management, in which the empty-loaded rate and total demand are selected as key factors affecting taxi dispatching, and the impacts of taxi fares on driver income and travel demand are taken into account. After the validation of the model, taxi operations data derived from a prior analysis of origin-destination data of Beijing taxis are used as input for the model to simulate the taxi market in Beijing. Finally, economic and environmental implications are provided for the government to optimise policies on taxi management. PMID- 29454531 TI - Orbital atherectomy for the treatment of small (2.5mm) severely calcified coronary lesions: ORBIT II sub-analysis. AB - OBJECTIVES: We assessed the safety and efficacy of orbital atherectomy to modify severely calcified coronary plaque prior to stent implantation in patients with small vessel (2.5mm) disease. BACKGROUND: Severe coronary artery calcification increases the risk of adverse clinical events during percutaneous coronary intervention (PCI). Patients who undergo PCI of small vessels have worse clinical outcomes including higher rates of perforation and dissection. The outcomes of orbital atherectomy of small diameter vessels (2.5mm) are unknown. METHODS: ORBIT II was a single-arm, multicenter trial which prospectively enrolled patients with severely calcified coronary lesions treated with orbital atherectomy prior to stenting in 49U.S. sites. The primary endpoint was the 3year rate of major adverse cardiac events, which was the composite of cardiac death, myocardial infarction, and target vessel revascularization. RESULTS: Of the 443 patients, 55 (12.4%) had reference vessel diameters (RVD) of 2.5mm and 388 (87.6%) had RVD >2.5. The rates of severe angiographic complications were similar in both groups. The primary endpoint was similar in both groups (30.6% vs. 22.5%, p=0.22), as were the rates of cardiac death (9.8% vs. 6.3%, p=0.33) and myocardial infarction (12.8% vs. 10.9%, p=0.67). Target vessel revascularization was numerically higher in the small vessel group (16.8% vs. 9.3%, p=0.13). CONCLUSIONS: Patients with small coronary vessel disease had comparable clinical outcomes compared to the larger diameter group following orbital atherectomy. Subsequent studies are required to establish the optimal revascularization approach for such patients with small coronary vessel disease burdened by heavily calcified lesions.

PMID- 29454534 TI - Sarcomatoid Carcinoma of the Lung: The Mayo Clinic Experience in 127 Patients. AB - BACKGROUND: Pulmonary sarcomatoid carcinoma (PSC) is an unusual form of non-small cell lung cancer (NSCLC). Because of its rarity and heterogeneity, the treatment and prognosis of PSC have not been clearly described. METHODS AND MATERIALS: We retrospectively evaluated all patients with a diagnosis of PSC from 1997 to 2015 at the Mayo Clinic (Rochester, MN). The clinical characteristics, treatment details, and outcomes were collected. The survival rates of the PSC patients were compared with those for other subtypes of NSCLC. We used propensity score matching to minimize the bias resulting from to imbalanced comparison groups. RESULTS: The study included 127 PSC patients. The median age at diagnosis was 68 years (range, 32-89 years), most of whom were men (61%) and smokers (82%). The clinical stage was I, II, III, and IV in 15.9%, 20.6%, 22.2%, and 41.3%, respectively. The median survival time was 9.9 months (95% confidence interval [CI], 7.6-12.6 months). The 1-, 2-, and 5-year survival rates were 42%, 23%, and 15%, respectively. Most patients received multimodality treatment. Of the 3 patients who received neoadjuvant chemotherapy, a partial response was demonstrated in 2. Twenty-five patients who underwent palliative chemotherapy were evaluated for tumor response: 52% experienced progression, 40% stable disease, 8.0% a partial response, and 0% a complete response. Multivariate analysis showed T stage, M stage, and treatment with surgery plus neoadjuvant chemotherapy or surgery plus adjuvant therapy were independent prognostic factors (P < .05). In matched analysis, multivariate models revealed worse overall survival for PSC compared with adenocarcinoma (hazard ratio, 2.38; 95% CI, 1.61 2.53) and squamous cell carcinoma (hazard ratio, 2.20; 95% CI, 1.44-2.34). CONCLUSION: We found the outcome of PSC to be significantly worse than that of adenocarcinoma and squamous cell carcinoma. Neoadjuvant or adjuvant chemotherapy, in addition to surgical resection, should be considered. PMID- 29454535 TI - Insurance-mandated preoperative diet and outcomes after bariatric surgery. AB - BACKGROUND: Despite a lack of demonstrated patient benefit, many insurance providers mandate a physician-supervised diet before financial coverage for bariatric surgery. OBJECTIVES: To compare weight loss between patients with versus without insurance mandating a preoperative diet. SETTING: University hospital, United States. METHODS: Retrospective study of all patients who underwent laparoscopic Roux-en-Y gastric bypass or sleeve gastrectomy over a 5 year period, stratified based on whether an insurance-mandated physician supervised diet was required. Weight loss outcomes at 6, 12, and 24 months postoperation were compared. Linear mixed-models and backward-stepwise selection were used. P<0.05 was considered significant. RESULTS: Of 284 patients, 225 (79%) were required and 59 (21%) were not required to complete a preoperative diet by their insurance provider. Patients without the requirement had a shorter time to operation from initial consultation (P = .04), were older (P<.01), and were more likely to have government-sponsored insurance (P<.01). There was no difference in preoperative weight or body mass index or co-morbidities. In unadjusted models, percent excess weight loss was superior in the group without an insurance mandated diet at 12 (P = .050) and 24 (P = .045) months. In adjusted analyses, this group also had greater percent excess weight loss at 6 (P<.001), 12 (P<.001), and 24 (P<.001) months; percent total weight loss at 24 months (P = .004); and change in body mass index at 6 (P = .032) and 24 (P = .007) months. There was no difference in length of stay or complication rates. CONCLUSIONS: Insurance-mandated preoperative diets delay treatment and may lead to inferior weight loss. PMID- 29454536 TI - The role of the OVOL1-OVOL2 axis in normal and diseased human skin. AB - OVOLs (OVO-like proteins) are ubiquitously conserved genes encoding a C2H2 zinc finger transcription factor in mammals. Functional studies on OVOL1 and OVOL2 using knockout mice have suggested that these genes play a pivotal role in the development of epithelial tissues arising from germ cells; however, the role of the OVOL1-OVOL2 axis in normal and diseased tissues remains unclear. This review highlights recent advances in understanding how the OVOL1-OVOL2 axis modulates cell differentiation and proliferation in human keratinocytes, hair follicles, and benign or malignant skin tumors including squamous cell carcinoma and malignant melanoma. Furthermore, OVOL1 has been shown to be involved in the expression of skin barrier proteins including filaggrin (FLG), and its mutation or dysfunction leads to the development of atopic dermatitis (AD). OVOL1 has also been identified as a susceptibility gene for AD by genome-wide association studies, in addition to FLG. Therefore, we discuss the relationship between OVOL1 and FLG in the development of AD.

PMID- 29454538 TI - Cobalamin deficiency presenting with thrombotic microangiopathy (TMA) features: A systematic review. AB - INTRODUCTION: Cobalamin deficiency may result in hematologic characteristics similar to thrombotic microangiopathy (TMA). To facilitate diagnosis, we reviewed reported cases of acquired cobalamin deficiency presenting with TMA features (c.def-TMA). METHODS: A literature search identified reports of c.def-TMA. Deficiency was defined as B12 levels of <118 pmol/L. Corrected reticulocyte counts and reticulocyte production indexes were calculated. Clinical features were presented as proportion abnormal and results summarized as medians and interquartile ranges (IQR). RESULTS: Patient level data was extracted from 41 identified cases. Median age (years) was 43 (30-55) with 21/41 (51%) being female. Cobalamin deficiency was noted in 35/40 (87.5%) but fold increases in MMA and HC were 30 and 6, respectively. The etiology was pernicious anemia in 28/41 (68%) cases. Anemia was both universal and severe, with hemoglobin levels of 55 g/L (4.7-6.6). Hypersegmented neutrophils were noted in 23/37 (62%), schistocytes in 29/38 (76%) and median LDH levels 3981 U/L (2004-5467). The RPI was <3.0% in all patients. Thrombocytopenia occurred in 33/41 (80.5%) with a median platelet count of 91 * 109/L (42-112). Plasma infusion or exchange was initiated in 14/41 (34%) with associated complications in 2 cases. CONCLUSION: Reticulocytopenia (RPI of <3.0%) was a universal finding that aids in differentiating c.def-TMA from other causes of hemolysis. C.def-TMA was associated with severe anemia, generally mild-moderate thrombocytopenia, and significant elevations in LDH. PMID- 29454539 TI - Quantification of the risk of urinary calcium stone formation in the urine collected at 2 times of the day in a group of children studied to rule out prelithiasis. AB - BACKGROUND: Various genetic and environmental factors are involved in urolithiasis. The 2 most common metabolic abnormalities are the increase in urinary calcium and low urinary citrate excretion. The ratio calculated between the concentrations of both substances is a good risk marker for the formation of calcium stones. OBJECTIVES: To determine whether the risk of urinary calcium stone formation changes throughout the day in the same patient. METHODS: We studied 56 children (23V, 33M) to check if they had prelithiasis. Calcium, citrate, and creatinine concentrations were determined in two urine samples collected one before dinner and the other in the morning. It was collected if they had ultrasound stones and if there was a history of urolithiasis in first and/or second degree relatives. RESULTS: In 25 patients (44.6%), renal ultrasound was positive for lithiasis (stones [n=9] and microlithiasis [n=16]). Forty of the 56 families (71.4%) had a history of urolithiasis. The percentage of abnormal urinary calcium (28.6%) concentrations and an abnormal calcium/citrate ratio (69.6%) was higher in the first urine of the day. The calcium/citrate ratio was the only studied parameter that was related to a family history of urolithiasis. There were no differences in urinary parameters between patients with and without ultrasound-confirmed kidney stones. CONCLUSIONS: Urinary concentrations of calcium and the calcium/citrate ratio vary throughout the day. Urine produced at night has a higher risk of urinary calcium stone formation. PMID- 29454540 TI - Asymmetric cellulose triacetate is a safe and effective alternative for online haemodiafiltration. AB - BACKGROUND: In post-dilution haemodiafiltration only synthetic membranes have been used to date. Asymmetric cellulose triacetate (ATATM) is now available, whose characteristics are suitable for this technique. OBJECTIVES: To describe the in vivo performance and behaviour of this membrane, to identify its depurative effectiveness, use in clinical practice and its biocompatibility, both acute and after one month of treatment. METHODS: Observational prospective study of 23 patients who were dialysed for 4 weeks using an ATATM membrane and who maintained their prior regimen. RESULTS: A total of 287 sessions were performed and 264 complete sessions were collected. With an effective time of 243.7 (17.6) min and a mean blood flow of 371.7 (23) ml/min, an average Kt of 56.3 (5.3) l was observed, as well as a convection volume of 27.1 (4.2) l, a filtration fraction of 29.9 (3.7) %, a urea reduction ratio (RR) of 81 (5.2) %, a creatinine RR of 74.7 (4.6) %, a beta2-microglobulin RR of 76.5 (4.8) % and a retinol binding protein RR of 18.6 (7.6) %. There were no technical problems or alarms. Changing the heparin dosage was not necessary. No increases in C3a or C5a concentrations or leukopenia were observed in the first 30min of the session. Neither the monocyte subpopulations nor IL-beta1 or IL-6 were significantly altered after one month of treatment. CONCLUSIONS: The new ATATM membrane achieves adequate Kt and convection volume, without technical problems and with good biocompatibility and inflammatory profiles. It is therefore a valid option for post-dilution haemodiafiltration, particularly in patients allergic to synthetic membranes. PMID- 29454541 TI - Participants, Physicians or Programmes: Participants' educational level and initiative in cancer screening. AB - This study is an in-depth examination of at whose initiative (participant, physician or screening programme) individuals participate in cervical, breast and colorectal cancer screening across the EU-28. Special attention is paid to (1) the association with educational attainment and (2) the country's cancer screening strategy (organised, pilot/regional or opportunistic) for each type of cancer screened. Data were obtained from Eurobarometer 66.2 'Health in the European Union' (2006). Final samples consisted of 10,186; 5443 and 9851 individuals for cervical, breast, and colorectal cancer, respectively. Multinomial logistic regressions were performed. Surprisingly, even in countries with organised screening programmes, participation in screenings for cervical, breast and colorectal cancer was most likely to be initiated by the general practitioner (GP) or the participant. In general, GPs were found to play a crucial role in making referrals to screenings, regardless of the country's screening strategy. The results also revealed differences between educational groups with regard to their incentive to participate in cervical and breast cancer screening and, to a lesser extent, in colorectal cancer screening. People with high education are more likely to participate in cancer screening at their own initiative, while people with less education are more likely to participate at the initiative of a physician or a screening programme. Albeit, the results varied according to type of cancer screening and national screening strategy. PMID- 29454542 TI - Classifying running speed conditions using a single wearable sensor: Optimal segmentation and feature extraction methods. AB - Accelerometers have been used to classify running patterns, but classification accuracy and computational load depends on signal segmentation and feature extraction. Stride-based segmentation relies on identifying gait events, a step avoided by using window-based segmentation. For each segment, discrete points can be extracted from the accelerometer signal, or advanced features can be computed. Therefore, the purpose of this study was to examine how different segmentation and feature extraction methods influence the accuracy and computational load of classifying running conditions. Forty-four runners ran at their preferred speed and 25% faster than preferred while an accelerometer at the lower back recorded 3D accelerations. Computational load was determined as the accelerometer signal was segmented into single and five strides, and corresponding small and large windows, with discrete points extracted from the single stride segments and advanced features computed from all four segment types. Each feature set was used to classify speed conditions and classification accuracy was recorded. Computational load and classification accuracy were compared across all feature sets using a repeated-measures MANOVA, with follow-up t-tests to compare feature type (discrete vs. advanced), segmentation method (stride- vs. window-based), and segment size (small vs. large), using a Bonferroni-adjusted alpha = 0.003. The five-stride (97.49 (+/-4.57)%) and large-window advanced (97.23 (+/-5.51)%) feature sets produced the greatest classification accuracy, but the large-window advanced feature set had a lower computational load (0.0041 (+/-0.0002)s) than the stride-based feature sets. Therefore, using a few advanced features and large overlapping window sizes yields the best performance of both classification accuracy and computational load. PMID- 29454543 TI - Characterization of the passive and active material parameters of the pubovisceralis muscle using an inverse numerical method. AB - The mechanical characteristics of the female pelvic floor are relevant to understand pelvic floor dysfunctions (PFD), and how they are related with changes in their biomechanical behavior. Urinary incontinence (UI) and pelvic organ prolapse (POP) are the most common pathologies, which can be associated with changes in the mechanical properties of the supportive structures in the female pelvic cavity. PFD have been studied through different methods, from experimental tensile tests using tissues from fresh female cadavers or tissues collected at the time of a transvaginal hysterectomy procedure, or by applying imaging techniques. In this work, an inverse finite element analysis (FEA) was applied to understand the passive and active behavior of the pubovisceralis muscle (PVM) during Valsalva maneuver and muscle active contraction, respectively. Individual numerical models of women without pathology, with stress UI (SUI) and POP were built based on magnetic resonance images, including the PVM and surrounding structures. The passive and active material parameters obtained for a transversely isotropic hyperelastic constitutive model were estimated for the three groups. The values for the material constants were significantly higher for the women with POP when compared with the other two groups. The PVM of women with POP showed the highest stiffness. Additionally, the influence of these parameters was analyzed by evaluating their stress-strain, and force-displacements responses. The force produced by the PVM in women with POP was 47% and 82% higher when compared to women without pathology and with SUI, respectively. The inverse FEA allowed estimating the material parameters of the PVM using input information acquired non-invasively. PMID- 29454544 TI - Mapping the spatiotemporal evolution of solute transport in articular cartilage explants reveals how cartilage recovers fluid within the contact area during sliding. AB - The interstitial fluid within articular cartilage shields the matrix from mechanical stresses, reduces friction and wear, enables biochemical processes, and transports solutes into and out of the avascular extracellular matrix. The balanced competition between fluid exudation and recovery under load is thus critical to the mechanical and biological functions of the tissue. We recently discovered that sliding alone can induce rapid solute transport into buried cartilage contact areas via a phenomenon termed tribological rehydration. In this study, we use in situ confocal microscopy measurements to track the spatiotemporal propagation of a small neutral solute into the buried contact area to clarify the fluid mechanics underlying the tribological rehydration phenomenon. Sliding experiments were interrupted by periodic static loading to enable scanning of the entire contact area. Spatiotemporal patterns of solute transport combined with tribological data suggested pressure driven flow through the extracellular matrix from the contact periphery rather than into the surface via a fluid film. Interestingly, these testing interruptions also revealed dynamic, repeatable and history-independent fluid loss and recovery processes consistent with those observed in vivo. Unlike the migrating contact area, which preserves hydration by moving faster than interstitial fluid can flow, our results demonstrate that the stationary contact area can maintain and actively recover hydration through a dynamic competition between load-induced exudation and sliding-induced recovery. The results demonstrate that sliding contributes to the recovery of fluid and solutes by cartilage within the contact area while clarifying the means by which it occurs. PMID- 29454545 TI - Characterization of Urinary Stone Composition by Use of Whole-body, Photon counting Detector CT. AB - RATIONAL AND OBJECTIVES: This study aims to investigate the performance of a whole-body, photon-counting detector (PCD) computed tomography (CT) system in differentiating urinary stone composition. MATERIALS AND METHODS: Eighty-seven human urinary stones with pure mineral composition were placed in four anthropomorphic water phantoms (35-50 cm lateral dimension) and scanned on a PCD CT system at 100, 120, and 140 kV. For each phantom size, tube current was selected to match CTDIvol (volume CT dose index) to our clinical practice. Energy thresholds at [25, 65], [25, 70], and [25, 75] keV for 100, 120, and 140 kV, respectively, were used to generate dual-energy images. Each stone was automatically segmented using in-house software; CT number ratios were calculated and used to differentiate stone types in a receiver operating characteristic (ROC) analysis. A comparison with second- and third-generation dual-source, dual energy CT scanners with conventional energy integrating detectors (EIDs) was performed under matching conditions. RESULTS: For all investigated settings and smaller phantoms, perfect separation between uric acid and non-uric acid stones was achieved (area under the ROC curve [AUC] = 1). For smaller phantoms, performance in differentiation of calcium oxalate and apatite stones was also similar between the three scanners: for the 35-cm phantom size, AUC values of 0.76, 0.79, and 0.80 were recorded for the second- and third-generation EID-CT and for the PCD-CT, respectively. For larger phantoms, PCD-CT and the third generation EID-CT outperformed the second-generation EID-CT for both differentiation tasks: for a 50-cm phantom size and a uric acid/non-uric acid differentiating task, AUC values of 0.63, 0.95, and 0.99 were recorded for the second- and third-generation EID-CT and for the PCD-CT, respectively. CONCLUSION: PCD-CT provides comparable performance to state-of-the-art EID-CT in differentiating urinary stone composition.

AB - OBJECTIVE: To investigate the association between prostatic-specific antigen (PSA) levels and molecular tumor volume (MTV) measured in the 68Ga-PSMA PET/CT, both done in a short period of time, in prostate cancer patients with biochemical failure. METHODS: Eighty-four patients who underwent 68Ga-PSMA PET/CT and measurement of PSA levels in the same week (trigger-PSA) were studied in this retrospective analysis. MTV was calculated from the sum of the metastatic lesions. To determine the association between trigger-PSA level and PET/CT findings, Spearman rank correlation was used. RESULTS: The median MTV of metastatic bone disease (mBD) was significantly higher than in metastatic lymph nodes (mLN) (139.5 versus 17.7; P<.05). Disease was limited to the prostate in 8 patients (9.5%), mLN in 21 patients (25%), mBD in 32 patients (38.1%) and the 3 sites (prostate, mLN, and mBD) in 17 patients (20.2%). In 6 patients (6.14%), 68Ga-PSMA-PET/CT was not capable of detecting disease. The median trigger-PSA levels of patients with disease limited to the prostate (2.8ng/mL), mLN (6.8ng/mL), and for mBD (16.8ng/mL) was statically significant (P<.05). Positive patients had a mean trigger-PSA of 4.3ng/mL vs 1.5ng/mL in negative patients (P<.05). We established 3 threshold-points for trigger-PSA level detection rate:<=1ng/mL (47.3%), 1-4ng/mL (68.4%) and>=4ng/mL (96.7%). When trigger-PSA exceeded 4ng/mL, the MTV was higher (P<.001). CONCLUSION: The correlation of MTV with trigger-PSA is demonstrated, which may have an impact on management. However, trigger-PSA levels were not capable of distinguishing between localized or distant disease. An accurate detection of disease can lead to a better therapeutic strategy. PMID- 29454549 TI - Technology Advances to Improve Response to Cardiac Resynchronization Therapy: What Clinicians Should Know. AB - Cardiac resynchronization therapy (CRT) is a well-established treatment for symptomatic heart failure patients with reduced left ventricular ejection fraction, prolonged QRS duration, and abnormal QRS morphology. The ultimate goals of modern CRT are to improve the proportion of patients responding to CRT and to maximize the response to CRT in patients who do respond. While the rate of CRT nonresponders has moderately but progressively decreased over the last 20 years, mostly in patients with left bundle branch block, in patients without left bundle branch block the response rate is almost unchanged. A number of technological advances have already contributed to achieve some of the objectives of modern CRT. They include novel lead design (the left ventricular quadripolar lead, and multipoint pacing), or the possibility to go beyond conventional delivery of CRT (left ventricular endocardial pacing, His bundle pacing). Furthermore, to improve CRT response, a triad of actions is paramount: reducing the burden of atrial fibrillation, reducing the number of appropriate and inappropriate interventions, and adequately predicting heart failure episodes. As in other fields of cardiology, technology and innovations for CRT delivery have been at the forefront in transforming-improving-patient care; therefore, these innovations are discussed in this review.

PMID- 29454552 TI - Adjustment of the Vocal Tract Shape via Biofeedback: A Case Study. AB - In this study, an adjustment of the vocal tract shape toward selected sound waves in the frequency range of the first and second formants without phonation is discussed. The sound waves of a loudspeaker in front of the open mouth and amplified by the vocal tract are used as biofeedback signals. It is shown that the resonance amplification of the vocal tract complies with the concept of forced oscillation, with the driver being the sound source and the resonator being the vocal tract. An adjustment toward increased amplification via vocal tract resonance can be related to smaller bandwidths and lower damping. Furthermore, the applied adjustment frequencies are preserved as vocal tract resonances during exhalation and even phonation. This novel form of biofeedback might enrich standard voice training procedures by exercises without phonation. PMID- 29454551 TI - Rostral anterior cingulate cortex is a structural correlate of repetitive TMS treatment response in depression. AB - BACKGROUND: Repetitive transcranial magnetic stimulation (rTMS) is an effective treatment for medication-refractory major depression, yet the mechanisms of action for this intervention are poorly understood. Here we investigate cerebral cortex thickness as a possible biomarker of rTMS treatment response. METHODS: Longitudinal change in cortical thickness is evaluated relative to clinical outcomes across 48 participants in 2 cohorts undergoing left dorsolateral prefrontal cortex rTMS as a treatment for depression. RESULTS: Our results reveal changes in thickness in a region of the left rostral anterior cingulate cortex that correlate with clinical response, with this region becoming thicker in patients who respond favorably to rTMS and thinner in patients with a less favorable response. Moreover, the baseline cortical thickness in this region correlates with rTMS treatment response - those patients with thinner cortex before treatment tended to have the most clinical improvement. CONCLUSIONS: This study is the first analysis of longitudinal cortical thickness change with rTMS as a treatment for depression with similar results across two cohorts. These results support further investigation into the use of structural MRI as a possible biomarker of rTMS treatment response. PMID- 29454553 TI - Mapping nutrition and health data in conflict-affected countries. PMID- 29454554 TI - Geospatial inequalities and determinants of nutritional status among women and children in Afghanistan: an observational study. AB - BACKGROUND: Undernutrition is a pervasive condition in Afghanistan, and prevalence is among the highest in the world. We aimed to comprehensively assess district-level geographical disparities and determinants of nutritional status (stunting, wasting, or underweight) among women and children in Afghanistan. METHODS: The study used individualised data from the recent Afghanistan National Nutrition Survey 2013. Outcome variables were based on growth and weight anthropometry data, which we analysed linearly as Z scores and as dichotomous categories. We analysed data from a total of almost 14 000 index mother-child pairs using Bayesian spatial and generalised least squares regression models accounting for the complex survey design. FINDINGS: We noted that childhood stunting, underweight, and combined stunting and wasting were consistently highest in districts in Farah, Nangarhar, Nuristan, Kunar, Paktia, and Badakhshan provinces. District prevalence ranged from 4% to 84% for childhood stunting and 5% to 66% for underweight. Child wasting exceeded 20% in central and high conflict regions that bordered Pakistan including east, southeast, and south. Among mothers, dual burden of underweight and overweight or obesity existed in districts of north, northeast, central, and central highlands (prevalence of 15 20%). Linear growth and weight of children were independently associated with household wealth, maternal literacy, maternal anthropometry, child age, food security, geography, and improved hygiene and sanitation conditions. The mother's body-mass index was determined by many of the same factors, in addition to ethnolinguistic status and parity. Younger mothers (<20 years old) were more underweight and shorter than older mothers (aged 20-49 years). INTERPRETATION: Afghanistan's rapidly changing political, socioeconomic, and insecurity landscape has both direct and indirect implications on population nutrition. Novel evidence from our study can be used to understand these multifactorial determinants and to identify granular disparities for local level tracking, planning, and implementation of nutritional interventions.

AB - Many low-income people of color living with HIV are not virally suppressed. More research is needed to understand how socially marginalized, disengaged, or inconsistently engaged people living with HIV (PLWH) contend with antiretroviral therapy (ART)-related challenges, particularly in the context of interactions with HIV care providers. Twenty-seven semi-structured interviews were conducted with low-income Black and Hispanic PLWH in the New York City area who were currently, or recently, disengaged from outpatient HIV health care at the time of the interview. Participants valued patient-centered health care in which they felt genuinely heard and cared for by their HIV clinicians. This desire was particularly pronounced in the context of wanting to change one's ART regimen. Participant emphasis on wanting to manage ART-related challenges with their providers suggests that HIV providers have an instrumental role in helping their patients feel able to manage their HIV. PMID- 29454556 TI - Validity and Responsiveness of the Two-Minute Walk Test for Measuring Functional Recovery After Total Knee Arthroplasty. AB - BACKGROUND: The 2-minute walk test (2mwt) is a performance-based test that evaluates functional recovery after total knee arthroplasty (TKA). This study evaluated its validity compared with the modified Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Oxford Knee Score (OKS), modified Knee Score, Numerical Pain Rating Scale, and Timed Up and Go test, and its responsiveness in assessing functional recovery in TKA patients. METHODS: This prospective cohort study included 162 patients undergoing primary TKA between 2013 and 2015. We used patient-reported outcome measures (modified WOMAC, OKS, modified Knee Score, Numerical Pain Rating Scale) and performance-based tests (2mwt and Timed Up and Go test) at baseline and 3, 6, and 12 months postoperatively. The construct validity of 2mwt was determined between the 2mwt distances walked and other outcome measurements. To assess responsiveness, effect size and standardized response mean were analyzed. Minimal clinically important difference of 2mwt at 12 months after TKA was also calculated. RESULTS: All outcome measurements improved significantly from baseline to 3, 6, and 12 months postoperatively. Bivariate analysis revealed mild to moderate associations between the 2mwt and modified WOMAC function subscales, and moderate to strong associations with OKS. Mild to moderate correlations were found for pain and stiffness between 2mwt and other outcome measurements. The effect size and standardized response mean at 12 months were large, with a minimal clinically important difference of 12.7 m. CONCLUSION: 2mwt is a validated performance-based test with responsiveness properties. Being simple and easy to perform, it can be used routinely in clinical practice to evaluate functional recovery after TKA. PMID- 29454557 TI - Development of a risk-scoring system to evaluate the serosal invasion for macroscopic serosal invasion positive gastric cancer patients. AB - BACKGROUND: The status of serosal invasion is often discordance between pathological and intraoperative evaluation. Our study sought to develop a risk scoring system (RSS) to predict the probability of pT4a for macroscopic serosal invasion (MSI) positive patients and reevaluate the serosal invasion status. PATIENTS AND METHODS: A total of 1301 pT3/pT4a gastric cancer patients with curative surgery were reviewed. We constructed the RSS to predict the probability of pT4a and assigned MSI-positive patients into different risk groups based on the risk scores. The prognostic significance of these risk groups was also evaluated. RESULTS: Univariate and multivariate analyses identified that tumor location, Lauren type, Borrmann type, tumor size, lymphovascular invasion and pN stage were risk factors related to pT4a. Survival analyses showed that pT3 MSI positive patients in high-risk group had similar survival with pT4a patients. We incorporated these two groups into one stage and proposed a novel revised-T stage. Two-step multivariate analyses indicated that the revised-T stage showed better prediction ability for prognosis and peritoneal recurrence assessment than original pT stage and MSI status. CONCLUSIONS: In our present study, we developed a RSS to predict the probability of pT4a for MSI-positive patients. Based on our RSS, we proposed a treatment algorithm to reevaluate the tumor invasion for MSI positive patients in clinical practice. Future studies should include other preoperative predictors to improve the clinical utility of our model. PMID- 29454558 TI - Clinical characteristics and management of patients with atrial fibrillation treated with direct oral anticoagulants according to blood pressure control. AB - OBJECTIVE: To determine the clinical characteristics and management of hypertensive patients with nonvalvular atrial fibrillation (AF) treated with direct oral anticoagulants (DOACs) according to blood pressure (BP) control. METHODS: For this purpose, data from two observational, cross-sectional and multicenter studies were combined. In both studies, patients on chronic treatment with anticoagulants and that were on current treatment with DOACs at least for 3 months were included. Adequate BP was defined as a systolic BP<140mmHg and a diastolic BP<90mmHg (<140/85mmHg if diabetes). RESULTS: Overall, 1036 patients were included. Of these, 881 (85%) had hypertension that were finally analyzed. The presence of other risk factors and cardiovascular disease was common. Mean BP was 132.6+/-14.3/75.2+/-9.2mmHg and 70.5% of patients achieved BP goals. Those patients with a poor BP control had more frequently diabetes, and a history of prior labile INR. Patients had a high thromboembolic risk, but without significant differences according to BP control. By contrast, more patients with a poor BP control had a higher bleeding risk (HAS-BLED >=3: 24.0% vs 35.4%; P<0.001). HAS-BLED score was an independent predictor of poor BP control (odds ratio 1.435; 95% confidence interval 1.216-1.693; P<0.001). Satisfaction with anticoagulant treatment was independent of BP control. CONCLUSIONS: More than two thirds of our patients with hypertension and AF anticoagulated with DOACs achieve BP targets, what is clearly superior to that reported in the general hypertensive population. PMID- 29454559 TI - Update on Hereditary Colorectal Cancer: Improving the Clinical Utility of Multigene Panel Testing. AB - Colorectal cancer (CRC), one of the most common cancers, is a major public health issue globally, especially in Westernized countries. Up to 35% of CRCs are thought to be due to heritable factors, but currently only 5% to 10% of CRCs are attributable to high-risk mutations in known CRC susceptibility genes, predominantly the mismatch repair genes (Lynch syndrome) and adenomatous polyposis coli gene (APC; familial adenomatous polyposis). In this era of precision medicine, high-risk mutation carriers, when identified, can be offered various risk management options that prevent cancers and improve survival, including risk-reducing medication, screening for early detection, and surgery. The practice of clinical genetics is currently transitioning from phenotype directed single gene testing to multigene panels, now offered by numerous providers. For CRC, the genes included across these panels vary, ranging from well established, clinically actionable susceptibility genes with quantified magnitude of risk, to genes that lack extensive validation or have less evidence of association with CRC and, therefore, have minimal clinical utility. The current lack of consensus regarding inclusion of genes in CRC panels presents challenges in patient counseling and management, particularly when a variant in a less validated gene is identified. Furthermore, there remain considerable challenges regarding variant interpretation even for the well established CRC susceptibility genes. Ironically though, only through more widespread testing and the accumulation of large international data sets will sufficient information be generated to (i) enable well powered studies to determine if a gene is associated with CRC susceptibility, (ii) to develop better models for variant interpretation and (iii) to facilitate clinical translation. PMID- 29454560 TI - Bioactive Lipid Mediator Profiles in Human Psoriasis Skin and Blood. AB - Psoriasis is a chronic immune-mediated disease that represents a unique model for investigating inflammation at local and systemic levels. Bioactive lipid mediators (LMs) are potent compounds reported to play a role in the development and resolution of inflammation. Currently, it is not known to what extent these LMs are involved in psoriasis pathophysiology and related metabolic dysfunction. Here, we use targeted and untargeted liquid chromatography-tandem mass spectrometry approaches to quantify LMs in skin and peripheral blood from psoriasis patients and compared them with those of healthy individuals. Lesional psoriasis skin was abundant in arachidonic acid metabolites, as 8-, 12- and 15 hydroxyeicosatetraenoic acid, compared with adjacent nonlesional and skin from healthy individuals. Additionally, a linoleic acid-derived LM, 13 hydroxyoctadecadienoic acid, was significantly increased compared with healthy skin (607.9 ng/g vs. 5.4 ng/g, P = 0.001). These psoriasis skin differences were accompanied by plasma decreases in antioxidant markers, including glutathione, and impaired lipolysis characterized by lower concentrations of primary and secondary bile acids. In conclusion, our study shows that psoriasis skin and blood have disease-specific phenotype profiles of bioactive LMs represented by omega-6 fatty acid-oxidized derivatives. These findings provide insights into psoriasis pathophysiology that could potentially contribute to new biomarkers and therapeutics. PMID- 29454561 TI - Flexible Neural Hardware Supports Dynamic Computations in Retina. AB - The ability of the retina to adapt to changes in mean light intensity and contrast is well known. Classically, however, adaptation is thought to affect gain but not to change the visual modality encoded by a given type of retinal neuron. Recent findings reveal unexpected dynamic properties in mouse retinal neurons that challenge this view. Specifically, certain cell types change the visual modality they encode with variations in ambient illumination or following repetitive visual stimulation. These discoveries demonstrate that computations performed by retinal circuits with defined architecture can change with visual input. Moreover, they pose a major challenge for central circuits that must decode properties of the dynamic visual signal from retinal outputs. PMID- 29454562 TI - Long-term functional, subjective and psychological results after single digit replantation. AB - OBJECTIVE: The aim of this study was to analyse the long-term functional, subjective, and psychological results after single-digit replantation. METHODS: Thirty cases of digital replantation (14 thumbs, 12 index fingers, 2 middle fingers, 1 ring finger, and 1 little finger) in 30 patients (7 females and 23 males) with a mean age of 44.2 years (20-65 years) were evaluated at the end of a mean follow-up time of 36 months (19-50 months). The active range of motion of joints, grip and pinch strength, cutaneous sensibility, upper-extremity functioning, and subjective satisfaction were determined using the Disability of Arm, Shoulder, and Hand (DASH) questionnaire and the Michigan Hand Outcomes questionnaire (MHQ). Psychological sequelae, including depression, anxiety, and posttraumatic stress disorder (PTSD), were assessed. A correlation analysis among variables was also performed. RESULTS: The mean score for the DASH questionnaire was 6.6 (range: 0-39.2). The symptom of cold intolerance occurred in 53% of the patients. Two patients were diagnosed with depression, and only one patient exhibited PTSD. The DASH score had a good statistical correlation with total grip strength, pinch grip strength, and static two-point discrimination (S-2PD) (P < 0.05). Several aspects of the MHQ were also statistically relevant to some or all of the three objective results. Furthermore, the grip strength showed significant correlation with DASH and most aspects of the MHQ in multivariate logistic regression analysis (P < 0.05). CONCLUSION: Total grip strength is the most important factor positively related to subjective outcomes. The incidence rates of psychological symptoms after digit replantation are very low at long-term follow-up. LEVEL OF EVIDENCE: Level IV, therapeutic study.

PMID- 29454563 TI - Radiological and clinical outcomes of medial approach open reduction by using two intervals in developmental dysplasia of the hip. AB - OBJECTIVE: To evaluate the midterm clinical and radiological outcomes of the medial approach using two intervals for developmental hip dysplasia (DDH). METHODS: The study involved 62 hips of 47 patients (41 girls, 6 boys) treated with medial approach for DDH from 1999 to 2010. The age of the patients at surgery was 18.7 +/- 2.25 months. Follow up of the patients was 11.3 +/- 3.07 years. The age of the patients at the last follow up was 12.6 +/- 1.74 years. According to the Tonnis classification, 13 hips were grade II, 27 hips were grade III and 22 hips were grade IV. Patients were evaluated according to Omeroglu radiological criteria and modified McKay functional criteria. The presence of avascular necrosis (AVN) of the hip was questioned using the KalamchiMacEwen classification. RESULTS: Radiologically, forty eight (77%) hips were evaluated as "excellent", 8 (13%) hips as "good" and 5 (8%) hips as "fair plus" and 1 (%2) hip as "fair minus". Two (3%) patients had type 1 temporary AVN and one (1%) patient had type 4 AVN with coxa magna and overgrowth of the greater trochanter. According to McKay functional criteria, 56 (90%) hips had "excellent" and 6 (10%) had "good" results. Two (3.2%) hips of one patient had to be reoperated with Salter osteotomy and femoral shortening + derotation osteotomy. CONCLUSION: Medial approach using two separate intervals for tenotomy and capsulotomy does not jeopardize the medial circumflex or the femoral vessels and yields satisfactory midterm results for children 18 months old with dysplasia of the hip. LEVEL OF EVIDENCE: Level IV, therapeutic study. PMID- 29454565 TI - Investigation of the biomechanical and histopathological effects of autologous conditioned serum on healing of Achilles tendon. AB - OBJECTIVE: The aim of this study to evaluate the effects of autologous conditioned serum (ACS) on the healing of transected rat Achilles tendons via the assessment of biomechanical and histological parameters. METHODS: The study was conducted on 45 male Sprague-Dawley rats. Five rats were used as donors for ACS preparation. Animals were randomly assigned to the experimental or control group. In both groups, the Achilles tendon was cut transversally and then sutured. In the placebo control and ACS-treated groups, saline or ACS, respectively, was injected into the repair zone three times after surgery. Ten rats from each group (ACS group, n = 20; control group, n = 20) were euthanized at days 15 and 30 after surgery for histopathological (n = 5) and biomechanical (n = 5) testing. The histopathological findings were interpreted using the Bonar and Movin scales. Tendon remodelling was evaluated via the immunohistochemical staining of collagen type 3. Biomechanical effects were assessed by tensile testing. RESULTS: The Bonar and Movin scale scores were significantly better in the ACS-treated group on both day 15 (p = 0.003 and p = 0.003, respectively) and day 30 (p = 0.005 and p = 0.004, respectively). The immunohistochemical density of collagen type 3 was significantly lower in the ACS-treated group on day 30 (p = 0.018). The type 1/3 collagen ratios of the groups were similar on days 15 and 30, as determined by Sirius Red staining (p = 0.910 and p = 0.133, respectively). In the biomechanical assessment results, the ACS-treated group's maximum load to failure values were significantly higher on day 15 (p = 0.049). CONCLUSION: Injection of ACS had a positive effect on the histopathological healing of rat Achilles tendons on days 15 and 30 and on biomechanical healing on day 15. ACS treatment contributed to lowering the collagen type 3 density by day 30. According to our study, ACS may be favourable for the treatment of human Achilles tendon injuries and tendinopathies. PMID- 29454566 TI - Determinants of Stroke in Brazil: A Cross-Sectional Multivariate Approach from the National Health Survey. AB - OBJECTIVE: The objective of this study was to investigate the association between biological-health, socioeconomics, and behavioral determinants and stroke by evaluating the risk of stroke in the presence of each or all determinants grouped in a multivariate model. METHODS: This study is a transversal secondary data analysis of the Brazilian National Health Survey, released by the Brazilian Institute of Geography and Statistics. The prevalence, prevalence ratios, and confidence intervals were calculated for the main outcome. A multivariate regression model was applied, with the stroke as outcome and all other variables with a P value of .20 or lower in the univariate analysis included as explanatory variables to adjust for potential confounders and effect modifiers. RESULTS: The mean age was 43.3 +/- 16.6 years, ranging from 18 to 101 years. The prevalence of hypertension was 21.4%, and with regard to lifestyle habits, it was observed that 20.0% had smoked but stopped and 29.7% practiced physical activity in the last 30 days. The regression model showed that the odds ratio in the final model was weighted, with low schooling, smoking habit, overweight, low physical activity practice, diabetes, and hypertension being significantly associated with stroke. CONCLUSION: The multivariate model showed that the chance of stroke is high, both combined or isolated. PMID- 29454567 TI - Cilostazol May Decrease Plasma Inflammatory Biomarkers in Patients with Recent Small Subcortical Infarcts: A Pilot Study. AB - BACKGROUND: The mechanism of progressive neurological deficit in patients with recent small subcortical infarcts has not yet been clarified. Inflammatory biomarkers and the use of cilostazol may be associated with this phenomenon. METHODS: Between May 2013 and April 2014, we evaluated consecutive first-ever patients with stroke due to recent small subcortical infarcts within 48 hours of onset. We divided patients into 2 groups according to the use of antiplatelet agents (cilostazol with or without aspirin versus aspirin alone). Plasma biomarkers such as matrix metalloproteinase-9, interleukin-6, high sensitive C reactive protein, and amyloid beta precursor protein (APP770, indicating endothelial dysfunction) were measured twice: (1) within 24 hours; and (2) 1 week after their admission. Multivariable logistic regression analyses were performed to identify the variables independently associated with progressive neurological deficit and poor functional outcome. RESULTS: We analyzed 41 patients (male: 63.4%, mean age: 70.8 years). Most of the patients (90%) who were treated with cilostazol were concomitantly treated with aspirin. Matrix metalloproteinase-9 and high sensitive C-reactive protein were higher in patients with progressive neurological deficit compared with those without. APP770 were more likely to be decreased in cilostazol group compared with aspirin group. Multivariable analyses show that traditional risk factors such as age and National Institutes of Health Stroke Scale scores were independently associated with both progressive neurological deficit and poor functional outcome. CONCLUSIONS: Inflammatory biomarkers may be associated with progressive neurological deficit. Early initiation of cilostazol may decrease the levels of plasma biomarkers. PMID- 29454569 TI - Risk of recurrence following mesh associated incisional hernia repair using the retromuscular technique in patients with relevant medical conditions. AB - BACKGROUND: Incisional hernia is a common problem following open abdominal surgery. Hernia repair in patients with relevant medical conditions is a topic of controversy due to the high risk of morbidity and recurrence. We investigated the risk of recurrence in patients with relevant medical conditions managed with a prosthesis in the retromuscular position. METHODS: A retrospective review of the data of patients undergoing midline incisional hernia repair was performed. The outcomes of patients with relevant concomitant medical conditions defined as ASA scores >2 were compared with those of healthier patients with ASA scores <=2. RESULTS: 115 patients including 41 with ASA >2 and 74 with ASA <=2 were included for analysis. There were no statistically significant differences amongst both groups with regard to the size of the hernia defect, the duration of surgery (123.0 +/- 71 vs. 149.0 +/- 92 min, p = 0.73), the incidence of postoperative seroma (14.6% vs. 29.7%, p = 0.07), postoperative hematoma (12.2% vs. 4.1%, p = 0.10) and surgical site infection (14.6% vs. 8.1%, p = 0.27). No statistically significant difference was seen amongst both groups with respect to the rate of long-term recurrence after a median follow-up of 63.0 +/- 36 months (12.2% vs. 6.8%, p = 0.32). CONCLUSION: Relevant medical condition alone cannot be seen as a contraindication for midline incisional hernia repair using the retromuscular technique. Rates of morbidity and long-term recurrence following mesh-associated closure are not difference from those of healthier patients. PMID- 29454568 TI - Phenotypic heterogeneity of hereditary diffuse gastric cancer: report of a family with early-onset disease. AB - BACKGROUND AND AIMS: The time course for the development of clinically significant hereditary diffuse gastric cancer (HDGC) is unpredictable. Little is known about the progression from preclinical, indolent lesions to widely invasive, aggressive phenotypes. Gastroendoscopy often fails to detect early lesions, and risk-reducing/prophylactic total gastrectomy (PTG) is the only curative approach. We present an HDGC family with early-onset disease in which clinical and histologic findings provided insight into the understanding of different HDGC phenotypes. METHODS: The proband was diagnosed at age 18 years with widely invasive, metastatic DGC. CDH1 genetic testing identified a pathogenic, germline CDH1 variant (c.1901C>T, p.Ala634Val). Thirty family members were tested, and 15 CDH1 carriers were identified. RESULTS: Six family members had PTG, with negative preoperative workup. The proband's 14-year-old sister is the youngest patient, reported to date, to have PTG after negative preoperative biopsy sampling. Intramucosal HDGC foci were detected in all PTG specimens (1 33). In contrast to the "indolent" phenotype of these foci, the aggressive DGC from the proband showed pleomorphic cells, absent E-cadherin expression, increased proliferation (Ki-67 index), and activation of oncogenic events (p53, pSrc and pStat3 overexpression). All family members had Helicobacter pylori gastritis. Cag-A-positive strains were detected in all specimens, except in the proband's sister. CONCLUSIONS: HDGC is a heterogeneous disease regarding clinical behavior, endoscopic findings, histopathologic features, and immunophenotypic/molecular profile. The presence of bizarre, pleomorphic cells in endoscopic biopsy specimens is suggestive of advanced disease and should prompt clinical intervention. The involvement of a full multidisciplinary team is essential for the management of these patients. PMID- 29454570 TI - Fibrosis score impacts survival following resection for hepatocellular carcinoma (HCC): A Surveillance, End Results and Epidemiology (SEER) database analysis. AB - BACKGROUND/OBJECTIVES: Surgical extirpation for hepatocellular carcinoma (HCC) with background fibrosis remains a challenge. This study evaluated impact of fibrosis score on long term outcomes of patients undergoing surgical resection for HCC. METHODS: Using the Surveillance, Epidemiology and End Results (SEER) database (2004-2013), complete data on 1433 patients undergoing surgical resection for non-metastatic HCC were identified. Overall survival (OS) was estimated using the Kaplan-Meier method. Cox proportional hazards model were used to produce adjusted hazard ratios (HR). RESULTS: In this study, 54% (650/1433) patients had F5-6 fibrosis at the time for surgical resection of HCC. In adjusted models, F5/6 fibrosis significantly reduces overall survival (HR: 1.62, 95% CI: 1.34-1.94; p < 0.001). Median survival was significantly longer for patients with F0-4 fibrosis for T1a, T1b and T2 tumours as compared to F5-6 fibrosis, not for T3 and T4 tumours, even when stratified by extent of hepatectomy. There were no significant differences in 90-day post-operative mortality between fibrosis groups when stratified by T-classifications. CONCLUSION: Liver resection in patients with advanced fibrosis has significantly lower survival as compared to patients with F0-4 fibrosis in early stage (T1 and T2), not advanced tumours (T3 and T4). Improvement in patient selection and perioperative care for liver resection may offer consistent and clinically meaningful long-term survival in HCC. PMID- 29454571 TI - Feasibility of restorative proctocolectomy in patients with ulcerative colitis associated lower rectal cancer: A retrospective study. AB - BACKGROUND/OBJECTIVE: Restorative proctocolectomy (RP) may improve quality of life in patients with ulcerative colitis (UC)-associated lower rectal cancer to a greater extent than total proctocolectomy. However, patients with UC-associated cancer often have flat mucosal lesions that make it extremely difficult to endoscopically delineate the tumor margins. Therefore, there is a potential risk of residual tumor and local recurrence after RP in patients with UC-associated lower rectal cancer. The aim of this study was to assess the feasibility of RP in patients with UC-associated cancer of the lower rectum. METHODS: We retrospectively identified nine patients who had undergone RP for UC-associated lower rectal cancer at the Niigata University Medical and Dental Hospital between January 2000 and December 2016. The incidence of flat mucosal cancer, distal margin status, and oncologic outcomes were evaluated in the nine patients. RESULTS: Eight (89%) of the nine patients had flat mucosal cancer in the lower rectum. The median length of the distal margin was 22 mm (range 0-55 mm). No patient developed local or distant recurrence during follow-up. One patient had a positive distal margin. This patient underwent annual pouchoscopy, but had no local recurrence and died of pancreatic cancer 81 months after RP. The remaining eight patients were alive at the final observation. Five-year and 10-year overall survival rates in the nine patients were 100% and 66.7%, respectively. CONCLUSION: Patients with UC-associated lower rectal cancer often have lesions of the flat mucosal type. However, RP is feasible and not necessarily contraindicated in such patients. PMID- 29454572 TI - Presence of colon carcinoma cells at the resection line may cause recurrence following stapling anastomosis. AB - BACKGROUND/OBJECTIVE: The presence of carcinoma cells in the suture line may result in local recurrence. The purpose of this study was to assess whether carcinoma cells were present along the resection line where the distal clamp was applied. METHODS: During surgery, the rectum was clamped at least 3 cm distal to the palpable margin of the tumor mass. The rectum was divided distal and proximal to the clamp. The tissue inside the clamp was rinsed with normal saline, and the irrigation solution was sent for cytologic examination. RESULTS: In 134 patients with carcinoma of the rectosigmoid colon or rectum, we found four (3.0%) cases of positive cytology, and five cases (3.7%) with cytology indicting the presence of atypical cells highly suspicious for malignancy. It was postulated that the trapping of cancer cells in a double-staple anastomosis line may have resulted in local recurrence. CONCLUSION: This study indicates that double staple-line recurrence is related to the shedding of cancer cells during dissection and clamping. PMID- 29454573 TI - Revisiting donor risk over two decades of single-center experience: More attention on the impact of overweight. AB - OBJECTIVE: Morbidity rates after living donor hepatectomy vary greatly among centers. Donor morbidity in a tertiary center over the past two decades was revisited. METHODS: Clinical data and grading of complications were reviewed by a nontransplant surgeon based on Clavien 5 tier grading. Risk factors were analyzed. RESULTS: In total, 473 consecutive living liver donors from 1997 to 2016 were included for analysis; 305 were right liver donors and 168 left liver donors, and the corresponding morbidity rates were 27.2% and 9.5%. The majority (81/99, 81.2%) of complications were grade I and II. Donors with morbidity compared with those without were significantly younger, nonoverweight body figure (BMI < 25), more as the right liver donors, and longer length of hospital stay. Right liver donation had significantly higher morbidity rates than did left liver donation in earlier periods (before 2011), but not thereafter. Multivariate modeling revealed that right lobe donation and overweight (BMI >= 25 kg/m2) were significant factors associated with donor morbidity, with adjusted hazard ratios HR (95% confidence interval) of 3.401 (1.909-6.060) and 0.550 (0.304-0.996), respectively. Further, overweight was a paradoxical risk factor in right donor hepatectomy with HR 0.422 (0.209-0.851), but the effect was nonsignificant in left liver donors. Most complications in overweight donors were grade I and not specific to liver surgery. CONCLUSIONS: The overall complication rate was 20.9%. Overweight might be protective against morbidity in right hepatectomy and warrants further deliberation.

PMID- 29454576 TI - Janus face of complement-driven neutrophil activation during sepsis. AB - During local and systemic inflammation, the complement system and neutrophil granulocytes are activated not only by pathogens, but also by released endogenous danger signals. It is recognized increasingly that complement-mediated neutrophil activation plays an ambivalent role in sepsis pathophysiology. According to the current definition, the onset of organ dysfunction is a hallmark of sepsis. The preceding organ damage can be caused by excessive complement activation and neutrophil actions against the host, resulting in bystander injury of healthy tissue. However, in contrast, persistent and overwhelming inflammation also leads to a reduction in neutrophil responsiveness as well as complement components and thus may render patients at enhanced risk of spreading infection. This review provides an overview on the molecular and cellular processes that link complement with the two-faced functional alterations of neutrophils in sepsis. Finally, we describe novel tools to modulate this interplay beneficially in order to improve outcome. PMID- 29454577 TI - Morphological clues to the appropriate recognition of hereditary renal neoplasms. AB - An important emerging role of the surgical pathologist besides the traditional tasks of establishment of the diagnosis and documentation of prognostic and predictive factors, is to recognize the possibility of a hereditary condition in cases where the histology is suggestive for a familial cancer syndrome. In recent years, the knowledge regarding all of the above roles, including the role of recognition of familial cancer, has particularly expanded in renal neoplasms with the close scrutiny to morphology, molecular correlates and clinical features of the different sub-types of renal cell carcinoma. Awareness of these clinically distinctive sub-types and their associated histologic clues will prompt the pathologist for further immunohistochemical or molecular work up, to look for clinical information to support the suspected diagnosis of familial cancer, to alert managing physician/s to look for stigmata of history of familial cancer, which will permit triaging patients and their families for appropriate genetic counseling. This review provides a comprehensive review of the known sub-types of renal cell carcinoma that have a predilection to occur in the setting of hereditary disease; examples include renal cancers occurring in the background of von Hippel Lindau disease, hereditary leiomyomatosis and renal cell carcinoma syndrome, tuberous sclerosis, Birt Hogg Dube syndrome and succinate dehydrogenase deficiency. Herein we focus on diagnostic clues for renal tumors occurring in a non-pediatric setting that should prompt their correct recognition and reiterate the importance of the correct diagnosis.

PMID- 29454575 TI - Targeting complement-mediated immunoregulation for cancer immunotherapy. AB - Complement was initially discovered as an assembly of plasma proteins "complementing" the cytolytic activity of antibodies. However, our current knowledge places this complex system of several plasma proteins, receptors, and regulators in the center of innate immunity as a bridge between the initial innate responses and adaptive immune reactions. Consequently, complement appears to be pivotal for elimination of pathogens, not only as an early response defense, but by directing the subsequent adaptive immune response. The discovery of functional intracellular complement and its roles in cellular metabolism opened novel avenues for research and potential therapeutic implications. The recent studies demonstrating immunoregulatory functions of complement in the tumor microenvironment and the premetastatic niche shifted the paradigm on our understanding of functions of the complement system in regulating immunity. Several complement proteins, through their interaction with cells in the tumor microenvironment and in metastasis-targeted organs, contribute to modulating tumor growth, antitumor immunity, angiogenesis, and therefore, the overall progression of malignancy and, perhaps, responsiveness of cancer to different therapies. Here, we focus on recent progress in our understanding of immunostimulatory vs. immunoregulatory functions of complement and potential applications of these findings to the design of novel therapies for cancer patients. PMID- 29454580 TI - Are synechiae a complication of laparotomic myomectomy? AB - Laparotomic myomectomy is often the only realistic solution for symptomatic women with multiple or large myomas who wish to retain their fertility. The aim of this study was to document the rate of uterine synechiae and their associated risk factors after laparotomic myomectomy. This prospective observational study took place in a teaching hospital from May 2009 to June 2014. It included all women aged 18-45 years who had laparotomic myomectomies (without diagnostic hysteroscopy at the time of surgery) for myomas and a postoperative diagnostic office hysteroscopy 6-8 weeks later. The study included 98 women with a laparotomic myomectomy and a postoperative hysteroscopic follow-up. Women with a laparotomic myomectomy for a subserosal myoma were excluded. The intrauterine adhesion rate after laparotomic myomectomy was 25.51% (25/98); 44% (11/25) of them were complex intrauterine adhesions. Opening the uterine cavity was a major risk factor for these complex adhesions, with an OR of 6.42 (95% CI 1.27 to 32.52). Office hysteroscopy could be carried out after surgery in such cases. PMID- 29454579 TI - Nucleus accumbens inflammation mediates anxiodepressive behavior and compulsive sucrose seeking elicited by saturated dietary fat. AB - OBJECTIVE: The incidence of depression is significantly compounded by obesity. Obesity arising from excessive intake of high-fat food provokes anxiodepressive behavior and elicits molecular adaptations in the nucleus accumbens (NAc), a region well-implicated in the hedonic deficits associated with depression and in the control of food-motivated behavior. To determine the etiology of diet-induced depression, we studied the impact of different dietary lipids on anxiodepressive behavior and metabolic and immune outcomes and the contribution of NAc immune activity. METHODS: Adult C57Bl/6 mice were subjected to isocaloric high-fat/high sucrose diets (HFD), enriched in either saturated or monounsaturated fat, or a control low-fat diet (LFD). Metabolic responses, anxiodepressive behavior, and plasma and NAc inflammatory markers were assessed after 12 weeks. In separate experiments, an adenoviral construct inhibiting IKKbeta, an upstream component of the nuclear factor kappa-b (NFkB) pathway, was a priori injected into the NAc. RESULTS: Both HFDs resulted in obesity and hyperleptinemia; however, the saturated HFD uniquely triggered anxiety-like behavior, behavioral despair, hyperinsulinemia, glucose intolerance, peripheral inflammation, and multiple pro inflammatory signs in the NAc, including reactive gliosis, increased expression of cytokines, antigen-presenting markers and NFkB transcriptional activity. Selective NAc IKKbeta inhibition reversed the upregulated expression of inflammatory markers, prevented anxiodepressive behavior and blunted compulsive sucrose-seeking in mice fed the saturated HFD. CONCLUSIONS: Metabolic inflammation and NFkB-mediated neuroinflammatory responses in the NAc contribute to the expression of anxiodepressive behavior and heightened food cravings caused by a diet high in saturated fat and sugar. PMID- 29454581 TI - Emerging roles of microglial cathepsins in neurodegenerative disease. AB - Alzheimer's disease (AD) is one of the leading causes of dementia, and its prevalence is expected to increase dramatically due to the aging global population. Microglia-driven neuroinflammation may contribute to the progression of AD. Microglia, the immune cells of the central nervous system (CNS), become chronically activated by the pathological proteins of AD including amyloid-beta peptides (Abeta). Such adversely activated microglia secrete mediators that promote inflammation and damage neurons. Cathepsins are proteases that are expressed by all brain cell types, and most of them are found both intra- and extra-cellularly. Microglia express and secrete several different cathepsins, which support various immune functions of microglia, in addition to their involvement in key neuroinflammatory pathways. This review focuses specifically on microglial cathepsins B, D and S, which have been implicated in AD pathogenesis; we identify their roles relevant to microglial involvement in AD pathogenesis. As dysregulated microglial function and neuroinflammation can contribute to AD progression, cathepsins should be considered as potential therapeutic targets for the development of effective AD treatment options. We conclude that the specific inhibition of microglial cathepsin B may lead to neuroprotective outcomes in AD, while the functions of this cysteine protease in neurons appears to be very complex and further studies are required to fully elucidate the pathophysiological role of neuronal cathepsin B. Examination of the CNS roles of cathepsins is limited by the shortage of highly selective inhibitors, with CA-074 being the only available specific cathepsin B inhibitor. We also conclude that non-specific inhibition of aspartic proteases, including cathepsin D, may promote adverse CNS effects, and may not be safe as AD therapeutics. Finally, cathepsin S inhibition has shown promise in preclinical studies due to its neuroprotective and anti-inflammatory effects; however, the many homeostatic roles of cathepsin S must be considered during the subsequent stages of development of cathepsin S inhibitors as AD therapeutics. Discovery of novel, highly selective inhibitors of various cathepsins and their clinical testing are required for the development of effective future AD therapies. PMID- 29454582 TI - Predictors and Outcomes of Cardiac Surgery-Associated Delirium. A Single Centre Retrospective Cohort Study. AB - BACKGROUND: The predictors and independent outcome association of delirium after cardiac surgery are important and yet poorly characterised. METHODS: We performed a retrospective observational study of cardiac surgery patients between January 2009 and March 2016. We defined delirium using ICD-10 diagnostic codes. Multivariable analysis was conducted to find independent associations between baseline variables, delirium, and key clinical outcomes. RESULTS: We studied 2447 study patients (28.7% female, median age was 66 [IQR 57-74] years). Delirium was coded for in 12.9% of patients overall, and in 22.9% of those aged >75years. Increasing age, Charlson co-morbidity index, admission not from home, peripheral vascular disease, respiratory disease, preoperative atrial fibrillation, duration of cardiopulmonary bypass and nature of surgery were all independent predictors of delirium. Delirium was independently and strongly associated with increased risk of reintubation (OR 8.18 [95% CI 5.24-12.78]), tracheostomy (OR 10.44 [95% CI 5.91-18.45]), and increased length of stay by 113.7 [95% CI 99.7-127.7] ICU hours and 6.95 [95% CI 5.94-7.95] hospital days, but not 30-day mortality (OR 0.78 [95% CI 0.38-1.59]; p=0.5). CONCLUSIONS: Delirium is common in cardiac surgery patients and increases with age. Delirium was the strongest predictor of reintubation, need for tracheostomy, and prolongation of intensive care unit (ICU) and hospital length of stay. Delirium prevention and attenuation are a priority in cardiac surgery patients. PMID- 29454583 TI - Post-operative ventricular flow dynamics following atrioventricular valve surgical and device therapies: A review. AB - Intra-ventricular flow dynamics has recently emerged as an important evaluation and diagnosis tool in different cardiovascular conditions. The formation of vortex pattern during the cardiac cycle has been suggested to play important epigenetic and energy-modulation roles in cardiac remodelling, adaptations and mal-adaptations. In this new perspective, flow alterations due to different cardiovascular procedures can affect the long-term outcome of those procedures. Especially, repairs and replacements performed on atrioventricular valves are likely to exert direct impact on intra-ventricular flow pattern. In this review, current consensus around the roles of vortex dynamics in cardiac function is discussed. An overview of physiological vortex patterns found in healthy left and right ventricles as well as post-operative ventricular flow phenomenon owing to different atrioventricular valvular procedures are reviewed, followed by the summary of different vortex identification schemes used to characterise intraventricular flow. This paper also emphasises on future research directions towards a comprehensive understanding of intra-cardiac flow and its clinical relevance. The knowledge could encourage more effective pre-operative planning and better outcomes for current clinical practices. PMID- 29454584 TI - Fat-specific protein 27 is a novel target gene of liver X receptor alpha. AB - Fat-specific protein 27 (FSP27) is highly expressed in the fatty liver of genetically obese ob/ob mice and promotes hepatic triglyceride (TG) accumulation. The nuclear hormone receptor liver X receptor alpha (LXRalpha) also plays a critical role in the control of TG levels in the liver. The present study demonstrated transcriptional regulation of Fsp27a and Fsp27b genes by LXRalpha. Treatment with the LXR ligand T0901317 markedly increased Fsp27a and Fsp27b mRNAs in wild-type C57BL/6J and ob/ob mouse livers. A reporter assay indicated that two LXR-responsive elements (LXREs) are necessary for LXRalpha-dependent induction of Fsp27a and Fsp27b promoter activities. Furthermore, the LXRalpha/retinoid X receptor alpha complex is capable of directly binding to the two LXREs both in vitro and in vivo. These results suggest that LXRalpha positively regulates Fsp27a and Fsp27b expression through two functional LXREs. Fsp27a/b are novel LXR target genes in the ob/ob fatty liver.

AB - The 'hot cross' bun (HCB) sign refers to pontine cruciform hyperintensity on T2 weighted magnetic resonance image (MRI) which is frequently seen in multiple system atrophy and spinocerebellar ataxia types 2 and 3. We describe a 3 years old boy of encephalitis and his MRI image showed HCB sign in the pontine. After immunosuppressive treatment and followed up 14 months, he got a good outcome and the HCB sign narrowed nearly disappeared. PMID- 29454587 TI - Comparison of CT radiogenomic and clinical characteristics between EGFR and KRAS mutations in lung adenocarcinomas. AB - AIM: To compare computed tomography (CT) radiogenomic and clinical characteristics between patients with epidermal growth factor receptor (EGFR) and Kirsten rat sarcoma viral oncogene (KRAS) mutations in lung adenocarcinomas. MATERIALS AND METHODS: This study was a retrospective analysis of patients with histopathologically confirmed lung adenocarcinoma, who had complete clinical and imaging data, and were tested for EGFR and KRAS mutations. Of the 313 included patients, 116 had effective EGFR mutations (EGFR group), 31 had KRAS mutations (KRAS group), and 166 had no EGFR or KRAS mutations (control group). Multivariate analysis was used to evaluate CT imaging features and clinical data. RESULTS: Multivariate analysis showed that significant variables between the EGFR and control groups were spiculation (odds ratio [OR] 2.70, 95% confidence interval [CI]: 1.54-4.75, p=0.001), and multiple small metastatic nodules (OR=7.52, 95% CI: 1.44-39.17, p=0.017). Significant variables between the KRAS and the control group were multiple small metastatic nodules (OR=7.65, 95% CI: 1.18-49.50, p=0.033). CONCLUSIONS: Patients with EGFR or KRAS mutations are prone to multiple metastases in both lungs. In addition, effective EGFR mutations mostly occurred in patients with multiple spiculations. PMID- 29454586 TI - Isolation of two plasmids, pRET1100 and pRET1200, from Rhodococcus erythropolis IAM1400 and construction of a Rhodococcus-Escherichia coli shuttle vector. AB - With the aim of being able to co-express multiple genes, I searched for novel compatible plasmids and isolated two plasmid species, pRET1100 and pRET1200, from Rhodococcus erythropolis IAM1400. Sequencing analysis revealed that the pRET1100 plasmid is a double-stranded DNA molecule of 5444 bp with two possible open reading frames (ORFs), repT and div, and three minor ORFs. The cryptic replication protein, RepT, is not highly homologous to those from other plasmids that have been reported. The Rhodococcus-Escherichia coli shuttle vector pRET1102 was transformed into R. erythropolis JCM2895 harboring the pRE2895 plasmid. The recombinant R. erythropolis JCM2895 harbored two plasmid species. These results suggest that plasmid derivatives of pRET1100 and pRE2895 are fully compatible in R. erythropolis. I determined the minimum region of pRET1100 required for autonomous replication in R. erythropolis and constructed a high-copy plasmid, pRET1129, in R. erythropolis. PMID- 29454588 TI - Diagnostic performance of two corrected transluminal attenuation gradient metrics in coronary CT angiography for the evaluation of significant in-stent restenosis by dual-source CT: a validation study with invasive coronary angiography. AB - AIM: To determine the diagnostic potential of transluminal attenuation gradients (TAG) with exclusion of stented coronary segments (TAG-ExS) and TAG-corrected contrast opacification (CCO) excluding stented coronary segments (TAG-CCO-ExS) for the assessment of in-stent restenosis (ISR). MATERIALS AND METHODS: TAG-ExS and TAG-CCO-ExS were calculated in 93 coronary arteries with 190 stents. The diagnostic performances and the incremental values of the two metrics to coronary computed tomography angiography (CCTA) were analysed and compared. RESULTS: For all stents and stents >3 mm in diameter, TAG-ExS and TAG-CCO-ExS were significantly lower in >=50% than that in <50% of ISR (both p<0.05). For stent diameters <=3 mm, significantly lower TAG-CCO-ExS (p=0.000), but not TAG-ExS (p=0.059), was found in >=50% than in <50% of ISR. Addition of TAG-ExS or TAG-CCO ExS to CCTA, did not improve the diagnostic accuracy of CCTA significantly (all p>0.05). Only TAG-CCO-ExS had a significant impact on CCTA for the reclassifications of ISR (p=0.046) in stent diameters <=3 mm. CONCLUSIONS: TAG ExS and TAG-CCO-ExS did not provide incremental diagnostic value over CCTA in assessing ISR. TAG-CCO-ExS slightly enhanced the reclassifications of ISR for stents <=3 mm in diameter. PMID- 29454589 TI - A retrospective review of registrar out-of-hours reporting in a university hospital: the effect of time and seniority on discrepancy rates. AB - AIM: To assess the influence of time, intensity, and trainee seniority on radiology registrars' major and minor discrepancy rates during weekend reporting at a university teaching hospital. MATERIALS AND METHODS: A 12-month retrospective review was performed of out-of-hours trainee provisional reports for computed tomography (CT) and magnetic resonance imaging (MRI) in a university teaching hospital. From Friday 9.00 pm to Sunday 9.00 pm, the out-of-hours service is provided by a single registrar rotating every 12 hours. A busy shift was defined as more than 24 reports issued during the shift. A senior trainee was defined as having more than 2 years' experience on the on-call rota. Reports were compared to subsequent subspecialist consultant review with all discrepancies collected. Discrepancy rates were calculated for junior/senior registrars, time of shift, and for busy/less busy shifts. RESULTS: The total discrepancy rate was 11.1%, with a major discrepancy rate of 3%. Junior registrars had a lower total discrepancy rate (9.7% versus 12.2%, p=0.0065). Although there was no difference between major discrepancies, junior trainees made fewer minor discrepancies (7.1% versus 8.93%, p=0.03). The discrepancy rate was higher at night (12.3% versus 10.4%, p=0.0418). On a less busy shift, more discrepancies were made (12.8% versus 10%, p=0.0001). CONCLUSION: The major discrepancy rate of trainees is low. More discrepancies are made at night, and trainee seniority does not mitigate this problem. Night shifts are less busy in comparison to day shifts, which may explain why less busy shifts appear to yield more mistakes. PMID- 29454590 TI - Understanding how prostate cancer patients value the current treatment options for metastatic castration resistant prostate cancer. AB - : Several new compounds are now available for castration resistant prostate cancer (CRPC). Individual costs range between $40,000 and $93,000 with mean survival extensions from 2.4 to 4.8 months. Currently, it remains unclear how patients with prostate cancer (PCa) value the effect of these therapies in the setting of CRPC. OBJECTIVE: To assess patient understanding of core cancer concepts, opinions on the cost and overall benefit of CRPC drugs, whether out-of pocket costs would change opinions and whether patients would ultimately opt out of CRPC drug treatment for an end-of-life (EOL) premium. PATIENTS AND METHODS: We conducted a qualitative survey among patients with various PCa states ranging from active surveillance to CRPC and from various familial, financial and educational demographics. Through a series of hypothetical scenarios, we extrapolated opinions on CRPC drug value, efficacy and monetary worth. We assessed patient willingness to accept an EOL ($50,000) premium in lieu of CRPC drug treatment. Statistically, chi-squared analysis and Fisher's exact test were used when appropriate. RESULTS: In total, 103 patients completed the questionnaire, one-half of whom did not understand "advanced PCa" state and more than one-third of the concept of palliative care despite multiple meetings with Urologists. Patients willingness-to-pay and proposed drug value was higher than that accepted by government when government funded, with costs exceeding $250,000 per person, but lower than that accepted by government when self-funded. A majority (60%) would accept/consider the EOL premium in the setting of CRPC. Patients with higher education were more skeptical about CRPC drug value and more likely to accept the EOL premium (P = 0.003.) CONCLUSION: Patients have an incomplete understanding of their own disease prognosis and its therapeutic options. This ultimately influences patient decision-making. Education, income and out-of-pocket costs diminished opinion of CRPC drugs considerably. As such, an EOL premium should be considered in subsets of patients. PMID- 29454591 TI - The effect of treatment at minority-serving hospitals on outcomes for bladder cancer. AB - OBJECTIVES: Healthcare for racial minorities is densely concentrated at a small subset of hospitals in the United States. Understanding long-term outcomes at these minority-serving hospitals is highly relevant to elucidating the sources of racial disparities in cancer care. We investigated the effect of treatment at a minority-serving hospital on overall survival and receipt of definitive treatment for bladder cancer. MATERIALS AND METHODS: Using the National Cancer Database, we identified all patients diagnosed with clinically localized, muscle-invasive bladder cancer between 2004 and 2012. We defined "minority-serving hospitals" as institutions in the top decile by proportion of Black and Hispanic patients within this cohort. Univariate and multivariable analyses were performed to assess the sociodemographic, clinical, and hospital-level factors influencing overall survival and receipt of definitive treatment for bladder cancer. RESULTS: In adjusted analyses, there was no significant difference in overall survival between patients treated at minority-serving hospitals versus those treated at nonminority-serving hospitals (hazard ratio = 0.95, 95% CI: 0.90-1.01). There was also no significance in receipt of definitive treatment between the two hospital types (odds ratio [OR] = 0.85, 95% CI: 0.68-1.06). Black race was independently associated with increased likelihood of mortality (hazard ratio = 1.08, 95% CI: 1.03-1.14) and decreased odds of receiving appropriate definitive treatment (OR = 0.73, 95% CI: 0.66-0.82). CONCLUSIONS: There was no difference between minority serving and nonminority-serving hospitals in overall survival or receipt of definitive treatment. Black patients suffered worse survival and were less likely to receive definitive treatment for bladder cancer regardless of the type of hospital in which they were treated. PMID- 29454592 TI - Effective Antimicrobial Stewardship Strategies for Cost-effective Utilization of Telavancin for the Treatment of Patients With Hospital-acquired Bacterial Pneumonia Caused by Staphylococcus aureus. AB - PURPOSE: Clinicians and stewardship programs are challenged with positioning of novel, higher priced antibiotic agents for the treatment of clinical infections. We developed a decision-analytic model to describe costs, including drug, total treatment costs, and health care outcomes, associated with telavancin (TLV) compared with vancomycin (VAN) for patients with Staphylococcus aureus (SA) hospital-acquired bacterial pneumonia (HABP). METHODS: This decision-analytic model assessed the treatment of SA-HABP with TLV versus VAN. Data were obtained from the ATTAIN (Assessment of Telavancin for Treatment of Hospital-Acquired Pneumonia) clinical trials on the following: the probability of clinical cure; probability of nephrotoxicity; and prevalence of polymicrobial infection (30%), methicillin-resistant Staphylococcus aureus (MRSA) (68%), and SA with VAN MIC >=1 ug/mL (85%). Data on length of stay for cure (10 days), failure (10 additional days), and nephrotoxicity (3.5 days) were based on literature. Cost per treated patient and incremental cost-effectiveness ratio (ICER) per additional cure were calculated for SA-HABP and for monomicrobial SA-HABP. One-way sensitivity analyses were performed. FINDINGS: Patients with SA-HABP were sub-grouped by methicillin susceptibility (n = 140, 32%) or resistance (n = 293, 68%), and occurrence of polymicrobial (n = 128, 30%) vs monomicrobial (n = 305, 70%) infections. Under the base case, hospital cost for patients with HABP treated with TLV was $42,564 and with VAN, it was $42,296. Telavancin was associated with higher drug ($2082) and nephrotoxicity ($467) costs and lower intensive care unit (-$1738) and ventilator (-$114) costs. ICER was $4156 per additional cure. ICER was sensitive to probabilities of cure, length of treatment in cures, intensive care unit cost, TLV cost, and additional length of stay due to failure. For monomicrobial SA-HABP, TLV was associated with a net cost savings of $907 per patient and yielded economic dominance. IMPLICATIONS: Our decision-analytic model suggests that TLV for monomicrobial SA-HABP is associated with higher drug acquisition costs but a favorable ICER relative to VAN, provided that effective antimicrobial stewardship limits therapy to 7 days. Sensitivity analyses suggest a potential economic benefit of TLV treatment with appropriate patient selection. Antimicrobial stewardship programs may be able to reduce total costs through judicious use of novel antimicrobial agents. ClinicalTrials.gov identifiers: NCT00107952 and NCT00124020.

PMID- 29454594 TI - Low magnesium intake is associated with increased knee pain in subjects with radiographic knee osteoarthritis: data from the Osteoarthritis Initiative. AB - OBJECTIVE: As magnesium mediates bone and muscle metabolism, inflammation, and pain signaling, we aimed to evaluate whether magnesium intake is associated with knee pain and function in radiographic knee osteoarthritis (OA). METHODS: We investigated the associations between knee pain/function metrics and magnesium intake from food and supplements in 2548 Osteoarthritis Initiative cohort participants with prevalent radiographic knee OA (Kellgren-Lawrence score >=2). Magnesium intake was assessed by Food Frequency Questionnaire (FFQ) at baseline. WOMAC and Knee Injury and Osteoarthritis Outcome Score (KOOS) scores were reported annually with total follow up of 48 months. Analyses used linear mixed models. RESULTS: Among participants with baseline radiographic knee OA the mean total magnesium intake was 309.9 mg/day (SD 132.6) for men, and 287.9 mg/day (SD 118.1) for women, with 68% of men and 44% of women below the estimated average requirement. Subjects with lower magnesium intake had worse knee OA pain and function scores, throughout the 48 months (P < 0.001). After adjustment for age, sex, race, body mass index (BMI), calorie intake, fiber intake, pain medication use, physical activity, renal insufficiency, smoking, and alcohol use, lower magnesium intake remained associated with worse pain and function outcomes (1.4 points higher WOMAC and 1.5 points lower KOOS scores for every 50 mg of daily magnesium intake, P < 0.05). Fiber intake was an effect modifier (P for interaction <0.05). The association between magnesium intake and knee pain and function scores was strongest among subjects with low fiber intake. CONCLUSION: Lower magnesium intake was associated with worse pain and function in knee OA, especially among individuals with low fiber intake. PMID- 29454595 TI - Growth hormone promotes synaptogenesis and protects neuroretinal dendrites against kainic acid (KA) induced damage. AB - There is increasing evidence that suggests a possible role for GH in retinal development and synaptogenesis. While our previous studies have focused largely on embryonic retinal ganglion cells (RGCs), our current study demonstrates that GH has a synaptogenic effect in retinal primary cell cultures, increasing the abundance of both pre- (SNAP25) and post- (PSD95) synaptic proteins. In the neonatal chick, kainate (KA) treatment was found to damage retinal synapses and abrogate GH expression. In response to damage, an increase in Cy3-GH internalization into RGCs was observed when administered shortly before or after damage. This increase in internalization also correlated with increase in PSD95 expression, suggesting a neuroprotective effect on the dendritic trees of RGCs and the inner plexiform layer (IPL). In addition, we observed the presence of PSD95 positive Muller glia, which may suggest GH is having a neuroregenerative effect in the kainate-damaged retina. This work puts forth further evidence that GH acts as a synaptogenic modulator in the chick retina and opens a new possibility for the use of GH in retinal regeneration research.

AB - The present study comparatively analyzed the blood glucose and insulin concentration, the temporal and spatial expression of brain-gut peptides and the key enzymes of glycolysis and gluconeogenesis in Japanese flounder by intraperitoneal injection (IP) and oral administration (OR) of glucose. Samples were collected at 0, 1, 3, 5, 7, 9, 12, 24 and 48 h after IP and OR glucose, respectively. Results showed that the hyperglycemia lasted for about 10 h and 21 h in OR and IP group, respectively. The serum insulin concentration significantly decreased at 3 h (1.58 +/- 0.21 mIU/L) after IP glucose. However, it significantly increased at 3 h (3.37 +/- 0.341 mIU/L) after OR glucose. The gene expressions of prosomatostatin, neuropeptide Y, cholecystokinin precursor and orexin precursor in the brain showed different profiles between the OR and IP group. The OR not IP administration of glucose had significant effects on the gene expressions of preprovasoactive intestinal peptide, pituitary adenylate cyclase activating polypeptide and gastrin in intestine. In conclusion, brain-gut peptides were confirmed in the present study. And the serum insulin and the brain gut peptides have different responses between the IP and OR administration of glucose. The OR could stimulate the brain-gut peptide expressions, which have effects on the insulin secretion and then regulate the blood glucose levels. However, in IP group, there is little chance to stimulate brain-gut peptide expression to influence the insulin secretion, which leads to a longer hyperglycemia.

PMID- 29454599 TI - Vascularized Bone Graft to the Lunate Combined With Temporary Scaphocapitate Fixation for Treatment of Stage III Kienbock Disease: A Report of the Results, a Minimum of 2 Years After Surgery. AB - PURPOSE: To report the outcomes of patients with stage III Kienbock disease treated by vascularized bone graft (VBG) followed by temporary scaphocapitate (SC) fixation, a minimum of 2 years after surgery. METHODS: Twenty-six patients (mean age, 35 years) with stage III Kienbock disease (16 with stage IIIA and 10 with stage IIIB), treated with VBG followed by SC fixation for 4 months, were retrospectively followed for at least 2 years (range, 24-121 months; mean, 61.8 months). The preoperative and postoperative assessments included range of motion (ROM) of the wrist, grip strength (GS), wrist pain, the modified Mayo wrist score (MMWS), carpal height ratio (CHR), Stahl index (STI), and radioscaphoid angle (RSA). The outcomes of each assessment of the stages IIIA and IIIB groups at the final examination were compared with those before surgery. RESULTS: In both stages IIIA and IIIB groups, GS increased after surgery. Decrease of CHR and STI was associated with the increase of RSA in the stage IIIA group after surgery, while RSA decreased, although neither CHR nor STI significantly increased in the stage IIIB patients. No patient demonstrated deterioration of the wrist pain after surgery. Twenty-one of 26 patients had an improved MMWS grade at the final follow-up. CONCLUSIONS: Vascularized bone graft combined with SC fixation for 4 months provided greater GS, pain relief, and functional improvement compared with before surgery in both stages IIIA and IIIB groups. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV. PMID- 29454600 TI - New Methods to Assess Forearm Torque and Lifting Strength: Reliability and Validity. AB - PURPOSE: To determine the repeatability and validity of new methods designed to objectively measure forearm torque and lifting strength in a clinical setting. METHODS: Twenty-eight healthy volunteers, 19 women and 9 men, were tested for lifting strength and forearm torque with the Kern and Baseline dynamometers. Two raters tested each participant on 3 occasions in the standing position. One of the raters also examined 15 subjects, 3 times, for forearm torque in the seated position and for lifting strength and forearm torque by the Work Simulator II, Baltimore Therapeutic Equipment (BTE II). Intraclass correlation coefficients (ICC) model 2,1 was used to calculate ICCs for intra- and interrater reliability. The same ICC model and Bland-Altman plots were used to analyze the validity and agreement between the new test methods and the BTE II equipment and for comparison between tests performed in the standing and seated positions. RESULTS: Intra- and interrater reliability for forearm torque measurements with both the Baseline and the BTE II demonstrated ICCs between 0.88 and 0.96. The comparison between the Baseline and the BTE equipment yielded lower ICCs of 0.74 to 0.88 but they were still substantial and in good agreement. The ICCs for torques recorded in the standing and seated position were 0.89 to 0.96. Lifting strength, measured in 3 different positions of forearm rotation, yielded ICC values between 0.84 and 0.96 for both raters and with both the Kern and the BTE II instruments. Similarly, comparisons between the Kern and the BTE II methods showed ICC values between 0.91 and 0.95. CONCLUSIONS: Both the Baseline and the Kern dynamometers demonstrated excellent intra- and interrater repeatability. Except for forearm torque test in direction of pronation, which had a slightly lower ICC of 0.74, our new methods were valid when the BTE II was used as the reference standard. Assessments in the standing or seated position for torque measurements made little difference. Thus, we found the quality of measurements performed with our new methods sufficient for future studies of forearm torque and lifting strength. CLINICAL RELEVANCE: Simple, yet reliable, methods to quantify torque and lifting strength in a clinical setting have the potential to improve evaluations of wrist and forearm disorders as well as their treatments.

AB - AIM: To compare two different types of inserts: Ultra-high molecular weight polyethylene (UHMWPE) and cross-linked polyethylene with a quantitative and qualitative study of polyethylene wear particles in synovial fluid 3 years after total knee arthroplasty. MATERIAL AND METHODS: A prospective, randomized, controlled cohort study with blinded evaluation was carried out on 25 patients undergoing staged bilateral total knee replacement, 6 months apart. Knee arthrocentesis was performed on 12 patients 3 years after surgery, and the polyethylene particles were analyzed. RESULTS: No significant differences were found in the number of particles generated by the two different types of inserts at 3 years from total knee arthroplasty (3,000*: x- cross-linked=849.7; x- UHMWPE=796.9; P=.63; 20,000*: x- cross-linked=66.3; x- UHMWPE=73.1; P=.76). Likewise, no differences in the probability of finding elongated (chi2=0.19; P=.66) or rounded (chi2=1.44; P=.23) particles in both types of inserts were observed. However, the probability of finding fibrillar particles is 3.08 times greater in UHMWPE. CONCLUSIONS: Cross-linked polyethylene does not significantly reduce the generation of polyethylene particles in patients with total knee arthroplasty, 3 years after the surgical procedure. PMID- 29454603 TI - ? PMID- 29454605 TI - Knowledge of sudden unexpected death in epilepsy (SUDEP) among 372 patients attending a German tertiary epilepsy center. AB - BACKGROUND: There is evidence that the sudden unexpected death in epilepsy (SUDEP) risk can be reduced by good seizure control, nocturnal supervision, and by early cardiopulmonary resuscitation if cardiorespiratory arrest occurs in the aftermaths of generalized tonic-clonic seizures (GTCS). These measures, however, may critically depend on the knowledge of patients and relatives on SUDEP. Here, we assessed the basic knowledge on SUDEP of people with epilepsy at a tertiary epilepsy center in Germany. METHODS: Adult patients with epilepsy and relatives or caregivers of patients with epilepsy aged 16years or older attending our outpatient clinic from January to March 2014 were given the opportunity to participate in a (assisted or unassisted) written survey. In the anonymized questionnaire, people were asked if they had already heard about SUDEP, by what means and if they wish to learn (more) about SUDEP. Furthermore, age, sex, epilepsy duration, highest degree of education, number of GTCS during the last year, and estimation of subjective impairment by their disease were assessed. Statistics were done using mixed linear or logistic regression models. RESULTS: A total of 372 patients' questionnaires were included in this survey. More than 87% of the participants had never heard of SUDEP before. Whereas about 50% of the participants wanted to learn more about SUDEP, about 40% did not. Only the age at survey was significantly associated with both being informed and the desire of learning more about SUDEP: Younger patients had more often heard (p=0.022) and wanted to know more about SUDEP (p=0.020). Thirty-nine patients were considered at high risk for SUDEP. Of these, only 6 patients (15%) knew about SUDEP prior to this survey, but 18 patients (46%) wanted to learn more about this fatal complication. CONCLUSION: Our data suggest that the level of information on SUDEP among people with epilepsy is poor in Germany regardless of sex, school education, or epilepsy severity. Additionally, a considerable proportion of people with epilepsy seems to prefer not getting detailed information on SUDEP. More efforts are required to understand the potential barriers of the education of patients and relatives on sudden death with the ultimate goal of decreasing the risk of SUDEP. PMID- 29454604 TI - Cytotoxic and inflammatory effects of alendronate and zolendronate on human osteoblasts, gingival fibroblasts and osteosarcoma cells. AB - OBJECTIVE: The aim of this paper was to assess the effects of zoledronate (ZOL) and alendronate (FOS) on apoptotic behavior and gene expression of pro- and inflammatory cytokines of three cell types (human osteoblasts, human gingival fibroblasts and human osteogenic sarcoma cell lines) during a period of 4 weeks. MATERIAL AND METHODS: Cell viability and proliferation was assessed via cell proliferation test (MTT), fluorescence diacetate analysis (FDA). Expression of inflammatory cytokines was investigated by using polymerase chain reaction. RESULTS: The proliferation and cell vitality of osteoblasts and fibroblasts were negatively affected in a dose dependent manner under ZOL and FOS administration. Osteosarcoma cells showed an increase in proliferation under lower doses of BP. ZOL had a significantly higher cytotoxic effect compared with FOS on osteoblasts and fibroblasts. ZOL increased the production of IL-6 in all cell types, whereas FOS only in osteosarcoma cell, which happened in dose dependent manner. Bisphosphonates could result in increase of IL-1beta expression of fibroblasts. An increase of IL-12 was observed at higher doses of ZOL administration among osteoblasts and FOS administration in osteosarcoma cells. CONCLUSION: ZOL and FOS could encourage cytotoxic and inflammatory reactions. PMID- 29454606 TI - Psychosocial outcome in epilepsy after extratemporal surgery. AB - OBJECTIVE: Only limited data exist on psychosocial long-term outcome after epilepsy surgery in patients with extratemporal epilepsy. The aim of this study was to investigate psychosocial outcome after extratemporal epilepsy surgery and to assess factors predicting favorable outcome. METHOD: Sixty-five out of 104 eligible patients who had undergone extratemporal epilepsy surgery at our epilepsy center between 1990 and 2015 (mean age: 42.2. years; 75% of the resections in the frontal lobe) completed a questionnaire asking about seizure status, employment status, marital and living situation, driving status, depressive symptoms, and quality of life (QOL). Follow-up was on average 9.2years after surgery (range: 1-26years). RESULTS: Thirty-eight (58%) patients were free of disabling seizures (Engel class I), and 28 (43%) have not experienced any seizures after surgery (Engel class IA). Employment rate in the primary labor market remained at 45%, but more patients lost employment (14%) than gained employment (8%). Postoperative employment was predicted by preoperative employment (p=.007), seizure freedom (p=.025), older age at seizure onset (p=.018), younger age at follow-up (p=.035), and female gender (p=.048). Seizure free patients were more likely to be driving; have a partner, particularly in males; and have lower depressive scores. Quality of life at follow-up was best predicted by employment (p=.012), partnership (p=.025), and seizure freedom (p=.025). In contrast, recurrence of seizures and early seizure onset were associated with poor psychosocial outcome, particularly in men. CONCLUSION: The study provides support that extratemporal surgery can lead to improved QOL and favorable psychosocial outcome. Seizure freedom is important but not the only determinant of good psychosocial outcome. PMID- 29454607 TI - Italian Wikipedia and epilepsy: An infodemiological study of online information seeking behavior. AB - Wikipedia is the most commonly accessed source of health information by both healthcare professionals and the lay public worldwide. We aimed to evaluate information-seeking behavior of Internet users searching the Italian Wikipedia for articles related to epilepsy and its treatment. Using Pageviews Analysis, we assessed the total and mean monthly views of articles from the Italian Wikipedia devoted to epilepsy, epileptic syndromes, seizure type, and antiepileptic drugs (AEDs) from January 1, 2015 to October 31, 2017. We compared the views of the article on epilepsy with those of articles focusing on Alzheimer's disease, migraine, multiple sclerosis, syncope, and stroke and adjusted all results for crude disease prevalence. With the only exception of the article on multiple sclerosis, the adjusted views for the Italian Wikipedia article on epilepsy were higher than those for the other neurological disorders. The most viewed articles on seizure type were devoted to tonic-clonic seizure, typical absence seizure, tonic convulsive seizures, and clonic convulsive seizures. The most frequently accessed articles on epilepsy syndromes were about temporal lobe epilepsy and Lennox-Gastaut syndrome. The most frequently viewed articles on AEDs were devoted to valproic acid, carbamazepine, and levetiracetam. Wikipedia searches seem to mirror patients' fears and worries about epilepsy more than its actual epidemiology. The ultimate reasons for searching online remain unknown. Epileptologists and epilepsy scientific societies should make greater efforts to work jointly with Wikipedia to convey more accurate and up-to-date information about epilepsy. PMID- 29454608 TI - miRNA-185 serves as a prognostic factor and suppresses migration and invasion through Wnt1 in colon cancer. AB - Colon cancer is one of the deadliest cancers worldwide; abnormal microRNA expression is common during colon cancer development. The aim of the present study was to elucidate the role played by miR-185 in this context. We used quantitative real-time PCR (qRT-PCR) to measure miR-185 expression levels in colon cancer cell lines. The effects of miR-185 on colon cancer cell proliferation and invasion were assessed using the MTT, colony-forming, wound healing, and transwell assays. A luciferase activity assay was used to confirm the target of miR-185. Our data showed that miR-185 was significantly down regulated in colon cancer cells and colonic cancer tissues compared with NCM460 normal colonic epithelial cells and adjacent normal tissues. A functional analysis revealed that ectopic expression of miR-185 significantly inhibited colon cancer cell proliferation, colony formation, migration, and invasion. In addition, western blot, qRT-PCR, and luciferase assays confirmed in colon cancer cells that Wnt1 was a downstream target of miR-185, in turn suppressing beta catenin-mediated signaling. In conclusion, we found that miR-185 inhibits colon cancer cell proliferation and invasion by targeting Wnt1, and that it serves as a tumor suppressor, indicating that the modulation of miR-185 levels may potentially be therapeutic in colon cancer patients. PMID- 29454609 TI - Deubiquitinase inhibitor b-AP15 activates endoplasmic reticulum (ER) stress and inhibits Wnt/Notch1 signaling pathway leading to the reduction of cell survival in hepatocellular carcinoma cells. AB - b-AP15, a potent and selective inhibitor of the ubiquitin-specific peptidase 14 (USP14), displays in vitro and in vivo antitumor abilities on some types of cancer cells. However, the mechanism underlying its action is not well elucidated. The purposes of the present study are to observe the potential impacts of b-AP15 on cell survival of hepatocellular carcinoma cells and to investigate whether and how this compound inhibits some survival-promoting signaling pathways. We found that b-AP15 significantly decreased cell viability and increased cell apoptosis in a dose-dependent manner in hepatocellular carcinoma cells, along with the perturbation of cell cycle and the decreased expressions of cell cycle-related proteins. We also demonstrated that the endoplasmic reticulum (ER) stress and the unfolded protein response (UPR) were enhanced by b-AP15 supplementation. The inhibition of ER stress/UPR only partly attenuated the cytotoxicity of b-AP15 on hepatocellular carcinoma cells. In addition, b-AP15 treatment inhibited Wnt/beta-catenin and Notch1 signaling pathways, and suppressed phosphorylation of STAT3, Akt, and Erk1/2, which were not restored by the inhibition of ER stress/UPR. Furthermore, the expression levels of signaling molecules in Notch1 were reduced by specific inhibitor of Wnt/beta-catenin pathway. Notably, either Wnt or Notch1 signaling inhibitor mitigated phosphorylation of STAT3, Akt, and Erk1/2, and mimicked the cytotoxicity of b-AP15 on hepatocellular carcinoma cells. These results clearly indicate that b-AP15 induced cytotoxic response to hepatocellular carcinoma cells by augmenting ER stress/UPR and inhibiting Wnt/Notch1 signaling pathways. This new finding provides a novel mechanism by which b-AP15 produces its antitumor therapeutic effects. PMID- 29454610 TI - Direct and indirect effects of ephedrine on heart rate and blood pressure in vehicle-treated and sympathectomised male rats. AB - We have investigated the cardiac and pressor responses to (+/-)-ephedrine and (-) ephedrine in pentobarbitone anaesthetized male wistar rats. The tachycardiac responses to (+/-)- and (-)-ephedrine were similar, but pressor responses to (-) ephedrine (10 mg/kg) were significantly greater than those to (+/-)-ephedrine, and for both, the pressor response was followed by a small depressor response. Sympathectomy did not affect pressor responses, but significantly increased the later depressor response to both compounds. Sympathectomy did not affect tachycardiac or depressor responses to the beta-adrenoceptor agonist isoprenaline, but significantly reduced the tachycardia to (+/-)-ephedrine. (+/-) Ephedrine contracted vas deferens from vehicle treatment animals, but in vas deferens from sympathectomised rats, (+/-)-ephedrine produced almost no tonic contraction (alpha1A-adrenoceptor mediated), but the phasic contraction was unaffected (alpha1D-adrenoceptor mediated). It is concluded, firstly, that (-) ephedrine is more potent than the racemate mixture at producing pressor responses. Secondly, since the depressor response to isoprenaline was unaffected, sympathectomy presumably reduced a pressor component to the response to (+/-)- and (-)-ephedrine. Hence, a component of the pressor response to both (+/-)- and (-)-ephedrine is indirect and may involve actions at alpha1A-adrenoceptors, at which ephedrine does not have marked direct actions. PMID- 29454611 TI - Taste receptor plasticity in relation to feeding history in two congeneric species of Papilionidae (Lepidoptera). AB - In the peripheral taste system of insects, the responsiveness of gustatory receptor neurons (GRNs) depends on several factors, such as larval instar, feeding history, physiological state and time of day. To study the role of the feeding history, the spike activity of the maxillary taste chemosensilla in the larvae of two related species of Lepidoptera (Papilio machaon L. and Papilio hospiton Gene) raised on different host plants, was recorded with electrophysiological techniques after stimulation with simple stimuli (sugars, bitters and inorganic salt) and host plant saps, with the aim of cross-comparing their response patterns and evaluating any effects of different feeding histories. For this purpose the larvae were raised each on their preferential host plant and, in addition, P. machaon larvae was also raised on Ferula communis, the host plant preferred by P. hospiton. The GRN spike activity of the lateral and medial sensilla of each test group was measured in response to simple and complex stimuli. The taste discrimination capabilities and modalities of the two species were measured and cross-compared with the aim of studying convergence and/or divergence linked to the insect feeding history. The results show that: a) the GRN responsiveness of both sensilla in P. machaon raised on Fe. communis differs significantly from that of P. machaon on Foeniculum vulgare, but is not different from P. hospiton on Fe. communis; b) P. machaon larvae raised on Fe. communis exhibit response spectra somewhat intermediate between those of P. machaon on fennel and of P. hospiton on Fe. communis, the latter two exhibiting a wider difference from each other; c) the pattern of GRNs activity generated by each plant sap in both sensilla of P. machaon raised on Fe. communis is different from that generated when raised on Fo. vulgare, while no difference is observed with P. hospiton. The data support the hypothesis that diet-related factors may influence peripheral chemosensitivity in lepidopterous larvae. PMID- 29454612 TI - Ecdysteroidogenesis and development in Heliothis virescens (Lepidoptera: Noctuidae): Focus on PTTH-stimulated pathways. AB - Post-embryonic development and molting in insects are regulated by endocrine changes, including prothoracicotropic hormone (PTTH)-stimulated ecdysone secretion by the prothoracic glands (PGs). In Lepidoptera, two pathways are potentially involved in PTTH-stimulated ecdysteroidogenesis, mitogen-activated protein kinase (MAPK) and phosphoinositide 3-kinase/protein kinase B/target of rapamycin (PI3K/Akt/TOR). We investigated the potential roles of both these pathways in Heliothis virescens ecdysteroidogenesis. We identified putative proteins belonging to MAPK and PI3K/Akt/TOR signaling cascades, using transcriptomic analyses of PGs from last (fifth) instar larvae. Using western blots, we measured the phosphorylation of 4E-BP and S6K proteins, the main targets of TOR, following the in vitro exposure of PGs to brain extract containing PTTH (hereafter referred to as PTTH) and/or the inhibitors of MAPK (U0126), PI3K (LY294002) or TOR (rapamycin). Next, we measured ecdysone production, under the same experimental conditions, by enzyme immunoassay (EIA). We found that in Heliothis virescens last instar larvae, both pathways modulated PTTH-stimulated ecdysteroidogenesis. Finally, we analyzed the post-embryonic development of third and fourth instar larvae fed on diet supplemented with rapamycin, in order to better understand the role of the TOR pathway in larval growth. When rapamycin was added to the diet of larvae, the onset of molting was delayed, the growth rate was reduced and abnormally small larvae/pupae with high mortality rates resulted. In larvae fed on diet supplemented with rapamycin, the growth of PGs was suppressed, and ecdysone production and secretion were inhibited. Overall, the in vivo and in vitro results demonstrated that, similarly to Bombyx mori, MAPK and PI3K/Akt/TOR pathways are involved in PTTH signaling stimulated ecdysteroidogenesis, and indicated the important role of TOR protein in H. virescens systemic growth. PMID- 29454613 TI - Isoquercetin attenuates oxidative stress and neuronal apoptosis after ischemia/reperfusion injury via Nrf2-mediated inhibition of the NOX4/ROS/NF kappaB pathway. AB - Isoquercetin (Iso) has been found to have neuroprotective effects against cerebral ischemic stroke. However, the exact molecular mechanism underlying its neuroprotective ability remains unclear. In this study, we aimed to evaluate the neuroprotective effects of Iso in primary culture of rat hippocampal neurons exposed to oxygen and glucose deprivation and reperfusion (OGD/R) injury and in rats subjected to middle cerebral artery occlusion and reperfusion (MCAO/R) injury. We found that rats treated with Iso exhibited a lower degree of infarct volume, and brain water content than the vehicle-treated rats. Treatment with Iso also improved the neurological deficits in MCAO/R rats as shown by the decreased modified neurological severity score. Iso treatment decreased the reactive oxygen species (ROS) and malondialdehyde (MDA) production, and increased the activity of superoxide dismutase (SOD) and catalase (CAT) in brains of MCAO/R rats and primary culture of rat hippocampal neurons exposed to OGD/R. Iso treatment prevents I/R-induced neuronal apoptosis in vivo and in vitro as indicated by increased cell viability and decreased number of TUNEL-positive cells, accompanying with downregulation of cleaved caspase-3 protein and upregulation of Bcl-2 protein. Moreover, Nrf2 knockdown weakened the anti-apoptotic and anti oxidant activities of Iso in primary culture of rat hippocampal neurons exposed to OGD/R. Interestingly, we found that Iso could induce Nrf2 translocation from cytoplasm to nucleus in primary culture of rat hippocampal neurons exposed to OGD/R. Iso activated the NOX4/ROS/NF-kappaB signaling pathway in in vivo and in vitro cerebral I/R injury models. Nrf2 knockdown blocked the inhibitory effect of Iso on protein expression of NOX4, p-IkappaBalpha and p-p65 in primary culture of rat hippocampal neurons exposed to OGD/R. All the data suggested that Iso protected against oxidative stress and neuronal apoptosis in in vivo and in vitro cerebral I/R injury models via Nrf2-mediated inhibition of the NOX4/ROS/NF-kappaB signaling pathway. Our findings suggested that Iso could be a potential agent for I/R brain injury. PMID- 29454614 TI - Selenium deficiency aggravates T-2 toxin-induced injury of primary neonatal rat cardiomyocytes through ER stress. AB - Keshan disease is a potentially fatal cardiomyopathy in humans. Selenium deficiency, T-2 toxin, and myocarditis virus are thought to be the major factors contributing to Keshan disease. But the relationship among these three factors is poorly described. This study aims to explore whether selenium deficiency aggravates T-2 toxin-induced cardiomyocyte injury and its underlying mechanism. Cardiomyocytes were isolated from neonatal rat and cultured at the physiological (2.0 MUM) or lower concentrations of selenium with different concentrations of T 2 toxin. Our results showed that selenium deficiencies aggravated T-2 toxin induced cardiomyocyte injury in a concentration-dependent manner as demonstrated by MTT bioassay, LDH activity, reactive oxygen species levels and caspase 3 protein expressions. T-2 toxin treatment significantly increased mRNA expressions for stress proteins GRP78 and CHOP in cardiomyocytes compared with the control. Selenium deficiencies further promoted GRP78, CHOP and p-eIF2alpha expressions. Knockdown of CHOP by the specific small interfering RNA eliminated the effect of selenium deficiencies on T-2 toxin-induced injury. It could be concluded that selenium deficiency aggravates T-2 toxin-induced cardiomyocyte injury through initiating more aggressive endoplasmic reticulum stress. PMID- 29454615 TI - Synthesis and biological investigation of new carbonic anhydrase IX (CAIX) inhibitors. AB - In this report, we describe the synthesis, characterization, in vitro anticancer activity and Carbonic anhydrase IX (CAIX) inhibition of new sulfamate conjugates of Betulin and Betulinic acid (BA). The betulinyl sulfamates were subjected to inhibit carbonic anhydrases (CA), e.g. CAIX, an attractive target for tumor selective therapy strategies in cancer cells. Data on combined in vitro antitumor activity with CAIX inhibition are very rare. The betulinyl sulfamates were tested against five tumor cell lines and normal human skin fibroblasts. The mode of cell death on MCF7 breast cancer cells induced by the most active compounds CAI1, CAI3 and CAI6 was investigated by Fluorescence Activated Cell Sorting (FACS) experiments. The compounds showed inhibitory activity towards CAIX, which was determined via in vitro enz-yme assay. Our preliminary investigations revealed that all compounds showed potent anticancer properties with IC50 values below 20 MUM against all tumor cells. Interestingly, among the panel of sulfamate conjugates, CAI3 found to be highly cytotoxic (average IC50 = 5-10 MUM) and possess high inhibitory activity (Ki = 1.25 nM) towards CAIX. Our results suggest that betulinyl sulfamates seem to be attractive substances, due to their possibility of targeted drug delivery they deserve to be proceeded for further pre-clinical (kinetic studies) and in vivo investigations. PMID- 29454616 TI - Zoledronate modulates intracellular vesicle trafficking in mast cells via disturbing the interaction of myosinVa/Rab3a and sytaxin4/VAMP7. AB - Nitrogen-containing bisphosphonates (NBPs) have been widely used as bone anti resorptive drugs for the treatment of osteoclast-dependent bone disorders. Zoledronate is currently the most potent NBP, and has potential as an inhibitor of farnesyl pyrophosphate synthase. The present study was undertaken to elucidate the possible effects of zoledronate on FcepsilonRI-dependent mast cell activity in vitro, which is essential for in maintaining homeostasis of the gastrointestinal mucosa. Treatment with zoledronate significantly diminished exocytosis of mast cells, which was reflected by a decrease of FcepsilonRI dependent histamine release compared to that in vehicle-treated mast cells. Our single-vesicle monitoring and biochemical results suggested that zoledronate modulates intracellular formation of the myosinVa/Rab3a complex and syntaxin4/VAMP7 complex, which are critical in vesicle motility, and therefore disturbs exocytosis via suppression of the velocity of intracellular vesicles and inhibition of membrane fusion. Our findings imply that oral administration of zoledronate could modulate mucosal immune function by blocking mast cell function, and this risk should be of concern in the clinical usage of NBPs. PMID- 29454617 TI - Antihypertensive potential of linalool and linalool complexed with beta cyclodextrin: Effects of subchronic treatment on blood pressure and vascular reactivity. AB - Linalool (LIN) is a monoterpene alcohol present in some aromatic medicinal plants with biological activities that can impact cardiovascular diseases. This chemical class is highly volatile and beta-cyclodextrin (beta-CD) has been employed to improve the pharmacological properties of monoterpenes. Thus, the aim of this study was to evaluate the cardiovascular effects of LIN free focusing on the antihypertensive properties of this monoterpene and to study whether LIN, complexed in beta-cyclodextrin (LIN-betaCD) is able to improve the pharmacological activity of LIN. Spontaneously hypertensive rats (SHR) were randomly divided into 5 groups, each treated daily for 21 days, in the following manner: group 1 (vehicle solution); group 2 (captopril; 30 mg/kg/day); group 3 (LIN; 100 mg/kg/day); group 4 (LIN; 50 mg/kg/day) and group 5 (LIN/beta-CD; 50 mg/kg/day). Daily body weight measurements were conducted and mean arterial pressure and heart rate were measured every 5 days. The mesenteric artery from treated animals was tested for phenylephrine and sodium nitroprusside (SNP) sensitivity. The SHR treated with vehicle demonstrated progressive increase in mean arterial pressure and captopril, a positive control, induced a significant decrease. After 21 days of treatment, the blood pressure of the SHR treated by ( )-LIN (100 mg/kg) was significantly reduced. In addition, various important cardiovascular parameters improved, including: the treatment with LIN prevented the development of cardiac hypertrophy, increased levels of the anti-inflammatory cytokine (IL-10), increased vasodilator responsiveness and reduced sensitivity to the sympathetic agonist. Furthermore, the inclusion complex containing LIN in beta-CD produced a higher antihypertensive profile when compared with uncomplexed form. Taking together, our results suggested that LIN shown a potential antihypertensive effect and beta-CD may be an important tool to improve the cardiovascular activity of LIN and other water-insoluble compounds. PMID- 29454618 TI - Natural small molecule bigelovin suppresses orthotopic colorectal tumor growth and inhibits colorectal cancer metastasis via IL6/STAT3 pathway. AB - Bigelovin, a sesquiterpene lactone, has been demonstrated to induce apoptosis, inhibit inflammation and angiogenesis in vitro, but its potential anti-metastatic activity remains unclear. In the present study, two colon cancer mouse models, orthotopic tumor allografts and experimental metastatic models were utilized to investigate the progression and metastatic spread of colorectal cancer after bigelovin treatments. Results showed that bigelovin (intravenous injection; 0.3-3 mg/kg) significantly suppressed tumor growth and inhibited liver/lung metastasis with modulation of tumor microenvironment (e.g. increased populations of T lymphocytes and macrophages) in orthotopic colon tumor allograft-bearing mice. Furthermore, the inhibitory activities were also validated in the experimental human colon cancer metastatic mouse model. The underlying mechanisms involved in the anti-metastatic effects of bigelovin were then revealed in murine colon tumor cells colon 26-M01 and human colon cancer cells HCT116. Results showed that bigelovin induced cytotoxicity, inhibition of cell proliferation, motility and migration in both cell lines, which were through interfering IL6/STAT3 and cofilin pathways. Alternations of the key molecules including Rock, FAK, RhoA, Rac1/2/3 and N-cadherin, which were detected in bigelovin-treated cancer cells, were also observed in the tumor allografts of bigelovin-treated mice. These findings strongly indicated that bigelovin has potential to be developed as anti tumor and anti-metastatic agent for colorectal cancer. PMID- 29454619 TI - Delineation of the functional properties and the mechanism of action of AA29504, an allosteric agonist and positive allosteric modulator of GABAA receptors. AB - The retigabine analog 2-amino-4-[(2,4,6-trimethylbenzylamino)-phenyl]-carbamic acid ethyl ester (AA29504) is a positive allosteric modulator (PAM) of gamma aminobutyric acidA receptors (GABAARs), and the modulator has been used in ex vivo/in vivo studies to probe the physiological roles of native delta-containing GABAARs. In this study, the functional properties and mode of action of AA29504 were investigated at human GABAARs expressed in Xenopus oocytes by two-electrode voltage clamp electrophysiology. AA29504 was found to be an allosteric GABAAR agonist displaying low intrinsic activities at 3-30 MUM. AA29504 was essentially equipotent as a PAM at the 13 GABAAR subtypes tested (EC50: 0.45-5.2 MUM), however GABA EC5-evoked currents through alphabetadelta subtypes were modulated to substantially higher levels than those through alphabetagamma2S subtypes (relative to GABA Imax). While the delta/gamma2S-difference clearly was key for this differential GABA efficacy modulation, studies of the AA29504-mediated modulation of different alpha4,5,6-containing alphabeta, alphabetagamma2S and alphabetadelta GABAARs revealed the alpha-subunit identity to be another important determinant. Based on its functional properties at numerous mutant GABAARs and on in silico analysis of its low-energy conformations, AA29504 is proposed to act through an allosteric site in the transmembrane beta(+)/alpha(-) interface in the GABAAR also targeted by etomidate and several other modulators. In contrast to these modulators, however, AA29504 did not display substantial beta2/beta3-over-beta1 GABAAR preference, which challenges the notion of ligands targeting this site always possessing this subtype-selectivity profile. Hence, the detailed pharmacological profiling of AA29504 both highlights the complexity of allosteric GABAAR modulation and provides valuable information about this modulator as a pharmacological tool. PMID- 29454621 TI - The G protein-coupled receptors deorphanization landscape. AB - G protein-coupled receptors (GPCRs) are usually highlighted as being both the largest family of membrane proteins and the most productive source of drug targets. However, most of the GPCRs are understudied and hence cannot be used immediately for innovative therapeutic strategies. Besides, there are still around 100 orphan receptors, with no described endogenous ligand and no clearly defined function. The race to discover new ligands for these elusive receptors seems to be less intense than before. Here, we present an update of the various strategies employed to assign a function to these receptors and to discover new ligands. We focus on the recent advances in the identification of endogenous ligands with a detailed description of newly deorphanized receptors. Replication being a key parameter in these endeavors, we also discuss the latest controversies about problematic ligand-receptor pairings. In this context, we propose several recommendations in order to strengthen the reporting of new ligand-receptor pairs.

AB - Pulmonary vaccination is one of the most promising routes for immunization owing to its noninvasive nature and induction of strong mucosal immunity and systemic response. In the present study, recombinant hepatitis B surface antigen loaded solid fat nanoemulsions (SFNs) as carrier system and monophosphoryl lipid A as an adjuvant-carrier system was prepared and evaluated as multiadjuvanted vaccine system for deep pulmonary vaccination. Deposition and clearance from the deep lung of rats were determined by gamma scintigraphy. Biodistribution of SFNs was determined by the live animal imaging system. SFNs dispersion showed slower clearance as compared with sodium pertechnetate control solution (***p <0.001) from the pulmonary region due to the virtue of particulate and hydrophobic nature of formulations. Humoral (sIgA and IgG) and cellular (IL-2 and IF-gamma) immune responses were found to be significant (***p <0.001) when compared with naive antigen (recombinant surface antigen without any excipient) solution. Data indicate that deep pulmonary immunization offers a stronger immune response with balanced humoral, mucosal, and cellular immunization, which further needs to be tested in higher animals to support this hypothesis for clinical translation of this so far neglected yet potential target tissue for immunization. PMID- 29454620 TI - Extracellular loops 2 and 3 of the calcitonin receptor selectively modify agonist binding and efficacy. AB - Class B peptide hormone GPCRs are targets for the treatment of major chronic disease. Peptide ligands of these receptors display biased agonism and this may provide future therapeutic advantage. Recent active structures of the calcitonin (CT) and glucagon-like peptide-1 (GLP-1) receptors reveal distinct engagement of peptides with extracellular loops (ECLs) 2 and 3, and mutagenesis of the GLP-1R has implicated these loops in dynamics of receptor activation. In the current study, we have mutated ECLs 2 and 3 of the human CT receptor (CTR), to interrogate receptor expression, peptide affinity and efficacy. Integration of these data with insights from the CTR and GLP-1R active structures, revealed marked diversity in mechanisms of peptide engagement and receptor activation between the CTR and GLP-1R. While the CTR ECL2 played a key role in conformational propagation linked to Gs/cAMP signalling this was mechanistically distinct from that of GLP-1R ECL2. Moreover, ECL3 was a hotspot for distinct ligand- and pathway-specific effects, and this has implications for the future design of biased agonists of class B GPCRs. PMID- 29454623 TI - Antisolvent Recrystallization Strategy to Screen Appropriate Carriers to Stabilize Filgotinib Amorphous Solid Dispersions. AB - Drugs in amorphous solid dispersions (ASDs) are highly dispersed in hydrophilic polymeric carriers, which also help to restrain recrystallization and stabilize the ASDs. In this study, microscopic observation after antisolvent recrystallization was developed as a rapid screening method to select appropriate polymers for the initial design filgotinib (FTN) ASDs. Using solvent evaporation, FTN ASDs with the polymers were prepared, and accelerated experimentation validated this screening method. Fourier-transform infrared spectroscopy, Raman scattering, and nuclear magnetic resonance revealed hydrogen-bonding formation in the drug-polymer binary system, which was critical for ASDs stabilization. A Flory-Huggins interaction parameter and water sorption isotherms were applied to evaluate the strength of the interaction between FTN and the polymers. The dissolution rate was also significantly improved by ASDs formulation, and the presence of the polymers exerted solubilization effects. These results suggested the efficacy of this screening method as a preliminary tool for polymer selection in ASDs design. PMID- 29454624 TI - The Synergetic Effects of Nonpolar and Polar Protic Solvents on the Properties of Felodipine and Soluplus in Solutions, Casting Films, and Spray-Dried Solid Dispersions. AB - The aim was to explore the effects of nonpolar and polar protic solvents composed of dichloromethane (DCM) and ethanol (EtOH) on the properties of felodipine (FLDP) and Soluplus in solutions, casting films, and spray-dried drug-rich or polymer-rich solid dispersions (SDs). Measurement of intrinsic viscosity and solubility indicated that FLDP and Soluplus were miscible. EtOH-DCM ranging from 20:80 to 50:50 induced the strongest molecular interactions for FLDP-Soluplus solvents systems. Accordingly, the casting films and spray-dried powders of FLDP and Soluplus were prepared using pure EtOH or DCM and their mixtures as solvents. Polarized light microscopy, differential scanning calorimetry, Fourier transform infrared spectroscopy, in vitro dissolution tests, and stability have been conducted to characterize these films or spray-dried powders. EtOH-DCM (50:50) showed deltaH 2-3 MPa1/2 higher than FLDP and Soluplus. It exhibited stronger inhibitory effects on phase separation and recrystallization of amorphous FLDP than pure DCM or EtOH in the drug-rich casting films, spray drying process, and spray-dried SDs exposure to 40 degrees C/RH75% for 1 month. Higher ratio of Soluplus may offset the effects of solvents on the dissolution and stability of polymer-rich SDs. In conclusion, combination of nonpolar and polar protic solvents is of high potential for spray drying to optimize drug-rich SDs. PMID- 29454625 TI - Intensified nitrogen and phosphorus removal by embedding electrolysis in an anaerobic-anoxic-oxic reactor treating low carbon/nitrogen wastewater. AB - A modified anaerobic-anoxic-oxic (AAO) reactor embedding electrolysis was constructed for treatment of low carbon/nitrogen (C/N) wastewater. The effect of different current conditions on the performance of reactor was investigated in this study. When the current ranged from 0 mA to 200 mA, the removal efficiency of total nitrogen (TN) increased from 61.25% (0 mA) to 75.60% (200 mA), and that of total phosphorus (TP) increased from 72.24% (0 mA) to 93.93% (200 mA). In addition, the removal efficiencies of chemical oxygen demand (COD) and NH4+-N were not affected. The results indicated that AAO reactor coupling electrolysis was an effective way to strengthen the removal of nitrogen and phosphorus for treatment of low C/N wastewater. PMID- 29454626 TI - Effect of adding low-concentration of rhamnolipid on reactor performances and microbial community evolution in MBBRs for low C/N ratio and antibiotic wastewater treatment. AB - This study aims to explore the potential of low-concentration of rhamnolipid in efficient treatment of wastewater with poor biodegradability. Six lab-scale moving bed biofilm reactors (MBBRs) were applied to investigate the effect of rhamnolipid concentration (0, 20, 50 mg/L) on pollutants removal, biomass accumulation, microbial morphology and community evolution in synthetic low C/N ratio (3:1) and antibiotic (50 MUg/L tetracycline) wastewater. 20 mg/L rhamnolipid treated groups exhibited significant increase (p < 0.05) of chemical oxygen demand (COD) removal and volatile solid (VS) content in both synthetic wastewater. Hydrogenophaga and Aeromonas were dominant in all reactors in which Aeromonas was positively correlated with the removal of COD and ammonia nitrogen (NH4+-N). Besides, Methyloversatilis became dominant only in 20 mg/L rhamnolipid treated groups and was positively correlated with VS. This study provides a novel and feasible strategy for treating poorly biodegradable wastewater by biofilm process with moderate amount of rhamnolipid. PMID- 29454627 TI - Changes in salsolinol production and salsolinol synthase activity in Parkinson's disease model. AB - Salsolinol is an endogenous neurotoxin derived from dopamine, and has been proved to cause the apoptosis of the dopaminergic neurons involved in the pathogenesis of Parkinson's disease (PD). Salsolinol synthase is the key enzyme in the biosynthesis of salsolinol, and its activity exists in most regions of rat brain. However, the activity distribution and its catalyzed function in vivo are still unknown. On the basis of the chromatographic assay established previously, we investigated the activity of salsolinol synthase and salsolinol production in both cell and rat model of PD induced by 6-hydroxydopamine (6-OHDA). The results show that the enzymatic activity increases in cell model and in the striatum region of PD rat brain. Nevertheless, there is a reduction of activity in hippocampus, cortex, and midbrain of PD model when compared with control. Conversely, the level of salsolinol was significantly increased in the midbrain region. Together, these results indicate the relationship between the oxidative stress induced by 6-OHDA and the activity of salsolinol synthase, suggesting the correlation of the endogenous neurotoxin and Parkinson's disease. Further research will provide more evidence and clarity on the function of Sal synthase. PMID- 29454629 TI - Postoperative pain and analgesia administration in children after urological outpatient procedures. AB - INTRODUCTION: There are limited data about pain patterns, analgesic requirements and factors predicting opioid requirements of children undergoing outpatient urologic surgery. This prospective study aimed to assess recovery profiles and pain medication requirements. METHODS: Patients between 6 months and 12 years of age were recruited prospectively between December 2013 and June 2014. Demographic and operative characteristics were collected. Following discharge home, the parents were asked to administer both acetaminophen and ibuprofen Q6H at a weight adjusted dose, based on a schedule, until the end of postoperative day 2, and to administer the medication as required on postoperative day 3. Pain severity was recorded using validated pain scores (Face, Legs, Activity, Cry, Consolability/Parents' Postoperative Pain Measurement). A morphine prescription was provided for breakthrough pain. A Likert scale was used to assess parent's satisfaction with the pain management. RESULTS: A total of 249 patients were recruited, 111 patients (45%) returned appropriately completed surveys and were included in the final analysis. Mean age was 44.1 months (SD = 37.3). The performed procedures were orchidopexy (31), hypospadias repair (26), hernia/hydrocele repair (15), Fowler-Stephens procedure (13), meatoplasty (7), phalloplasty (4), scrotoplasty (1), circumcision (7), and diagnostic laparoscopy (5). After discharge home 17 patients (15.3%) received morphine. Mean utilization of non-opioid analgesia was 79% on postoperative day 1, 67% on day 2, 36% on day 3, and 2% on day 4. Parental satisfaction was high (92.0% satisfied/very satisfied). No patient, anaesthetic or surgical factors were associated with opioid use or prolonged need for postoperative analgesia. CONCLUSION: The combination of scheduled non-opioid medications for maintenance and opioids for breakthrough pain provided satisfactory pain control after outpatient urologic surgery in children. There were no specific patient, anesthetic or surgical factors that predicted postoperative opioid requirements. PMID- 29454628 TI - Tunica vaginalis flap for salvaging testicular torsion: A matched cohort analysis. AB - INTRODUCTION: In testicular torsion, ischemia time from pain onset impacts testicular salvage. A tunica albuginea fasciotomy to relieve compartment pressure followed by a tunica vaginalis flap (TVF) may enhance salvage. OBJECTIVE: To define the optimal window of ischemia time during which TVF may be most beneficial to avoid orchiectomy. STUDY DESIGN: A retrospective cohort study of males presenting with testicular torsion at a single tertiary-care institution from January, 2003 to March, 2017. Ischemia time was defined as duration of pain from onset to surgery. Because TVF would be an option to orchiectomy, and it was found that ischemia time was longer in testicles that underwent orchiectomy, matching was performed. Cases of torsion treated with TVF were matched 1:1 with cases treated with orchiectomy on age at surgery, and ischemia time. Outcomes included postoperative viability, defined as palpable testicular tissue with normal consistency, and atrophy, defined as palpable decrease in size relative to contralateral testicle. Sensitivity analyses were performed restricting to the subgroups with postoperative ultrasound, >6 months' follow-up, and additionally matching for degrees of twist. RESULTS: A total of 182 patients met eligibility criteria, of whom 49, 36, and 97 underwent orchiectomy, TVF, and septopexy alone, respectively. Median follow-up was 2.7 months; 26% of patients had postoperative ultrasound (61% of TVF group). In the orchiectomy, TVF, and septopexy groups, respectively, median ischemia times were 51, 11, and 8 h, postoperative viability rates were 0, 86, and 95%, and postoperative atrophy rates were 0, 68, and 24%. After matching, 32 patients with TVF were matched to 32 patients who underwent orchiectomy. In the TVF group, postoperative viability occurred in 95% (19/20) vs 67% (8/12) of patients with ischemia times <=24 and >24 h, respectively. Atrophy occurred in 67% (12/18) vs 83% (10/12) of these same respective patients. Sensitivity analysis by ultrasound and longer follow-up found similar viability results, although atrophy rates were higher. Additional matching for degrees of twist showed lower viability and higher atrophy rates for increasing ischemia times. DISCUSSION: Patients who presented with testicular torsion with ischemia times <=24 h and who were being considered for orchiectomy may have benefitted most from TVF, albeit at high risk of atrophy. However, for ischemia times >24 h, TVF may still have preserved testicular viability in two-thirds of cases. A limitation was short follow-up. CONCLUSION: A TVF was a valid alternative to orchiectomy for torsed testicles, albeit with high testicular atrophy rates.

AB - End-stage renal disease is becoming a contemporary global concern with increasing prevalence. The available treatment strategies are limited to dialysis and renal transplantation. However, limited organ supply and autoimmune rejection are the shortcomings that limit widespread application of transplantation. Favorably, regenerative medicine is able to provide acellular natural scaffolds for renal transplantation. Experimental surgeries in animal models are a fundamental step in transplantation research. This video presents a practical method for transplantation of bilateral acellular kidneys in a rat model, which could serve as a key step for further research. PMID- 29454631 TI - Update on visual function and choroidal-retinal thickness alterations in Parkinson's disease. AB - Parkinson's disease (PD) is a neurodegenerative process that affects 7.5 million people around the world. Since 2004, several studies have demonstrated changes in various retinal layers in PD using optical coherence tomography (OCT). However, there are some discrepancies in the results of those studies. Some of them have correlated retinal thickness with the severity or duration of the disease, demonstrating that OCT measurements may be an innocuous and easy biomarker for PD progression. Other studies have demonstrated visual dysfunctions since early phases of the disease. Lastly, the most recent studies that use Swept Source OCT technology, have found choroidal thickness increase in PD patients and provide new information related to the retinal degenerative process in this disease. The aim of this paper is to review the literature on OCT and PD, in order to determine the altered retinal and choroidal parameters in PD and their possible clinical usefulness, and also the visual dysfunctions with higher impact in these patients.

AB - Primary effusion lymphoma (PEL) is a rare subtype of large B-cell lymphoma associated with human herpesvirus-8. Most cases are co-infected with Epstein-Barr virus (EBV). The prognosis of PEL is extremely poor and no optimal treatment regimen has been established. We report a case of EBV-negative PEL in a 49-year old human immunodeficiency virus-positive man, presenting with massive bilateral pleural effusion. PMID- 29454633 TI - Long-term sequelae after lung abscess in children - Two tertiary centers' experience. AB - AIM: The aim of the study was to describe the epidemiology and clinical characteristic of children hospitalized with pneumonia complicated by lung abscess, as well as to evaluate the long-term sequelae of the disease. METHODS: A retrospective review of medical records of all patients treated for pulmonary abscess in two tertiary centers was undertaken. Pulmonary function tests and lung ultrasound were performed at a follow-up. RESULTS: During the study period, 5151 children with pneumonia were admitted, and 49 (0.95%) cases were complicated with lung abscess. In 38 (77.5%) patients, lung abscess was treated solely with antibiotics, and in nine cases (16.3%) surgically. In 21 (51.21%) children complete radiological regression was documented. The mean time for radiological abnormalities regression was 84.14 +/- 51.57 days, regardless of the treatment mode. Fifteen patients were followed up at 61.6 +/- 28.3 months after discharge. Lung ultrasound revealed minor residual abnormalities: pleural thickening, subpleural consolidations and line B artefacts in 11 (73.3%) children. Pulmonary function tests results were abnormal in eight (53.3%) patients, the most frequent abnormality being hyperinflation. We did not find a restrictive disorder in any of the children. There were no deaths in our study. CONCLUSIONS: Lung abscess is a rare but severe complication of pneumonia in children. Most children recover uneventfully with no significant long-term pulmonary sequelae. PMID- 29454634 TI - Feminizing Genital Gender-Confirmation Surgery. AB - INTRODUCTION: For many patients with gender dysphoria, gender-confirmation surgery (GCS) helps align their physical characteristics with their gender identity and is a fundamental element of comprehensive treatment. This article is the 2nd in a 3-part series about the treatment of gender dysphoria. Non-operative management was covered in part 1. This section begins broadly by reviewing surgical eligibility criteria, benefits of GCS, and factors associated with regret for transgender men and women. Then, the scope narrows to focus on aspects of feminizing genital GCS, including a discussion of vaginoplasty techniques, complications, and sexual function outcomes. Part 3 features operative considerations for masculinizing genital GCS. AIM: To summarize the World Professional Association for Transgender Health's (WPATH) surgical eligibility criteria and describe how patients with gender dysphoria benefit from GCS, provide an overview of genital and non-genital feminizing gender-confirmation procedures, and review vaginoplasty techniques, preoperative considerations, complications, and outcomes. METHODS: A review of relevant literature through April 2017 was performed using PubMed. MAIN OUTCOME MEASURES: Review of literature related to surgical eligibility criteria for GCS, benefits of GCS, and surgical considerations for feminizing genitoplasty. RESULTS: Most transgender men and women who satisfy WPATH eligibility criteria experience improved quality of life, overall happiness, and sexual function after GCS; regret is rare. Penile inversion vaginoplasty is the preferred technique for feminizing genital GCS according to most surgeons, including the authors whose surgical technique is described. Intestinal vaginoplasty is reserved for certain scenarios. After vaginoplasty most patients report overall high satisfaction with their sexual function even when complications occur, because most are minor and easily treatable. CONCLUSION: GCS alleviates gender dysphoria for appropriately selected transgender men and women. Preoperative, intraoperative, and postoperative considerations of feminizing genital gender-confirmation procedures were reviewed. Hadj-Moussa M, Ohl DA, Kuzon WM.

AB - Down syndrome (DS) results from the triplication of genes located on human chromosome 21 (Hsa21). Though many cognitive and behavioral impairments are associated with DS, sleep disturbances remain poorly understood despite being a reported phenotype in approximately 60% of individuals diagnosed with DS. In this study, sleep and electroencephalography (EEG) oscillations were recorded from aged (12-14 mos.) Dp(16)1Yey/+ mice (Dp16), a mouse model of DS. We observed disrupted sleep demonstrated by increased activity during the dark phase and increased time awake at the expense of NREM sleep compared to wild-type mice. In addition, we found that Dp16 mice display significant differences in relative EEG power distribution among oscillation frequencies in both sleep and awake states. These results in Dp16 mice are consistent with sleep disturbances found in individuals with DS, and the abnormal EEG oscillations in aged Dp16 mice suggest a potential role for GABAergic activity in these sleep and EEG abnormalities. These sleep and EEG data reflect underlying differences in neuronal activity at the network level and thus are causative agents rather than merely symptoms of DS. PMID- 29454636 TI - Incisional hernia prevention and use of mesh. A narrative review. AB - Incisional hernias are a very common problem, with an estimated incidence around 15-20% of all laparotomies. Evisceration is another important problem, with a lower rate (2.5-3%) but severe consequences for patients. Prevention of both complications is an essential objective of correct patient treatment due to the improved quality of life and cost savings. This narrative review intends to provide an update on incisional hernia and evisceration prevention. We analyze the current criteria for proper abdominal wall closure and the possibility to add prosthetic reinforcement in certain cases requiring it. Parastomal, trocar-site hernias and hernias developed after stoma closure are included in this review. PMID- 29454637 TI - Tools to study pathogen-host interactions in bats. AB - Bats are natural reservoirs for a variety of emerging viruses that cause significant disease in humans and domestic animals yet rarely cause clinical disease in bats. The co-evolutionary history of bats with viruses has been hypothesized to have shaped the bat-virus relationship, allowing both to exist in equilibrium. Progress in understanding bat-virus interactions and the isolation of bat-borne viruses has been accelerated in recent years by the development of susceptible bat cell lines. Viral sequences similar to severe acute respiratory syndrome corona virus (SARS-CoV) have been detected in bats, and filoviruses such as Marburg virus have been isolated from bats, providing definitive evidence for the role of bats as the natural host reservoir. Although viruses can be readily detected in bats using molecular approaches, virus isolation is far more challenging. One of the limitations in using traditional culture systems from non reservoir species is that cell types and culture conditions may not be compatible for isolation of bat-borne viruses. There is, therefore, a need to develop additional bat cell lines that correspond to different cell types, including less represented cell types such as immune cells, and culture them under more physiologically relevant conditions to study virus host interactions and for virus isolation. In this review, we highlight the current progress in understanding bat-virus interactions in bat cell line systems and some of the challenges and limitations associated with cell lines. Future directions to address some of these challenges to better understand host-pathogen interactions in these intriguing mammals are also discussed, not only in relation to viruses but also other pathogens carried by bats including bacteria and fungi. PMID- 29454638 TI - Testosterone Levels and Prostate Cancer Prognosis: Systematic Review and Meta analysis. AB - Androgen receptor is the major driver of and testosterone the natural growth factor of prostate cancer (PC). Studies exploring the relationship among circulating testosterone levels, PC aggressiveness, and patient prognosis showed contradictory results. We performed a comprehensive literature search for studies reporting the independent relationship between serum testosterone and prognosis of PC patients. Meta-analyses using random effects models were conducted to estimate pooled hazard ratios (HRs) and 95% confidence intervals (CIs). We identified 25 articles that evaluated the prognostic value of testosterone in early-stage PC (8 studies), in advanced PC either before (4 studies) or during androgen deprivation therapy (ADT) (5 studies), and in castration-resistant PC (8 studies). In early PC, serum testosterone level was not prognostic in terms of overall survival (HR = 1.03; 95% CI, 0.99-1.08; P = .19) and biochemical recurrence (HR = 0.99; 95% CI, 0.87-1.13; P = .93). In advanced PC, higher testosterone levels before ADT were associated with a reduced risk of death (HR = 0.58; 95% CI, 0.45-0.74; P < .0001). During ADT, lower levels were associated with a reduced risk of death (HR = 0.48; 95% CI, 0.28-0.81; P = .006) and progression (HR = 0.59; 95% CI, 0.46-0.77; P < .0001). In castration-resistant PC patients, higher testosterone levels predicted a reduced risk of progression (HR = 0.33; 95% CI, 0.11-0.97; P = .04) but not of death (HR = 0.86; 95% CI, 0.69 1.07; P = .18). The heterogeneity of the included studies is a major limitation of this meta-analysis. The relationship between circulating testosterone and PC prognosis varies in different clinical settings and according to ADT administration. PMID- 29454639 TI - Neutrophil-to-lymphocyte Ratio, Platelet-to-lymphocyte Ratio, and C-reactive Protein as New and Simple Prognostic Factors in Patients With Metastatic Renal Cell Cancer Treated With Tyrosine Kinase Inhibitors: A Systemic Review and Meta analysis. AB - BACKGROUND: Inflammation plays a crucial role in cancer development. In this study, we evaluate the prognostic values of systemic inflammation markers such as neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and C reactive protein (CRP) for the progression-free survival and overall survival in patients with metastatic renal cell carcinoma treated with tyrosine kinase inhibitors. MATERIALS AND METHODS: PubMed and the Cochrane Library databases were searched for published studies on the effect of NLR, PLR, and CRP in patients with metastatic renal cell carcinoma treated with tyrosine kinase inhibitors. RESULTS: In the meta-analysis, NLR (hazard ratio [HR], 2.01; 95% confidence interval [CI], 1.27-3.18; P = .003) and PLR (HR, 6.96; 95% CI, 5.04-9.62; P < .001) had a significant influence on progression-free survival, whereas all considered proinflammatory markers had a significant impact on overall survival: NLR (HR, 2.14; 95% CI, 1.67-2.73; P < .001), PLR (HR, 14.67; 95% CI, 11.10-19.57; P < .001), and CRP (HR, 1.96; 95% CI, 1.26-3.05; P = .003). CONCLUSIONS: Inflammation markers such as NLR, PLR, and CRP are predictors of clinical outcome and could provide additional information to individualize treatment. PMID- 29454640 TI - Correction. PMID- 29454641 TI - Beyond the FRN: Broadening the time-course of EEG and ERP components implicated in reward processing. AB - Most reward-related electroencephalogram (EEG) studies focus exclusively on the feedback-related negativity (FRN, also known as feedback negativity or FN, medial frontal negativity or MFN, feedback error-related negativity or fERN, and reward positivity or RewP). This component is usually measured approximately 200-300 ms post-feedback at a single electrode in the frontal-central area (e.g., Fz or FCz). The present review argues that this singular focus on the FRN fails to leverage EEG's greatest strength, its temporal resolution, by underutilizing the rich variety of event-related potential (ERP) and EEG time-frequency components encompassing the wider temporal heterogeneity of reward processing. The primary objective of this review is to provide a comprehensive understanding of often overlooked ERP and EEG correlates beyond the FRN in the context of reward processing with the secondary goal of guiding future research toward multistage experimental designs and multicomponent analyses that leverage the temporal power of EEG. We comprehensively review reward-related ERPs (including the FRN, readiness potential or RP, stimulus-preceding negativity or SPN, contingent negative variation or CNV, cue-related N2 and P3, Feedback-P3, and late-positive potential or LPP/slow-wave), and reward-related EEG time-frequency components (changes in power at alpha, beta, theta, and delta bands). These electrophysiological signatures display distinct time-courses, scalp topographies, and reflect independent psychological processes during anticipatory and/or outcome stages of reward processing. Special consideration is given to the time-course of each component and factors that significantly contribute to component variation. Concluding remarks identify current limitations along with recommendations for potential important future directions. PMID- 29454642 TI - Moderate financial incentive does not appear to influence the P300 Concealed Information Test (CIT) effect in the Complex Trial Protocol (CTP) version of the CIT in a forensic scenario, while affecting P300 peak latencies and behavior. AB - Previous research indicated that the skin conductance response (SCR) of the Autonomic Nervous System (ANS) in the Concealed Information Test (CIT) is typically increased in subjects who are financially and otherwise incentivized to defeat the CIT (the paradoxical "motivational impairment" effect). This is not the case for RT-based CITs, nor for P300 tests based on the 3-stimulus protocol or Complex Trial Protocol for detection of cognitive malingering (although these are not the same as forensic CITs). The present report extends earlier studies of malingerers by running five groups of subjects (15-16 per group yielding 78 total) in a mock crime (forensic) scenario: paid (to beat the test) and unpaid, instructed and uninstructed, and simply guilty. There was no evidence that the "CIT effect" (probe-minus-irrelevant P300 differences) differed among groups, although behavioral differences among groups were seen. PMID- 29454643 TI - Proprioceptive stimuli and habit formation: Interresponse time mediated behavior in CD-1 mice. AB - The consolidation of behavioral sequences into relatively ballistic habits is thought to involve the formation of stimulus - response associations. Typically, the stimuli in these associations are assumed to be exteroceptive, i.e., external to the organism. However, responses, themselves, also possess stimulus properties that can mediate behavior. Indeed, these "proprioceptive cues" have long been hypothesized to underlie habit formation (Hull, 1934a, 1934b). One such stimulus involves the time durations between responses - a stimulus termed interresponse time (IRT). We hypothesize that IRTs can come to serve as stimuli that differentially control response elements during habit formation. To examine this hypothesis we report on two experiments that asked whether CD-1 mice utilize IRTs to structure behavior in a two-choice environment. In experiment 1, eight mice were exposed to a free-operant concurrent variable-interval (VI) 30-s VI 60-s reinforcement schedule. We found that switch and stay responses were differentially correlated with IRT durations. In Experiment 2 we directly and differentially reinforced stay/switch responses based on IRT durations in a two lever procedure. For four of the subjects, the probability of receiving reinforcement after switch responses was proportional to IRT duration. For five of the subjects, these reinforcement probabilities were inversely proportional to IRT duration. Regardless, all of our subjects learned to emit IRT-mediated switching behavior that matched the reinforcement contingencies. Together, Experiments 1 and 2 provide the first evidence of which we are aware that IRTs can come to control sequential choice behavior in mice. PMID- 29454644 TI - Testing aggressive behaviour in a feeding context: Importance of ethologically relevant stimuli. AB - The choice of stimuli used in tests of animal behaviour can have a critical effect on the outcome. Here we report two experiments showing how different foods influenced aggressive behaviour in competition tests at weaning among littermates of the domestic cat. Whereas in Experiment 1 canned food elicited almost no overt competition, a piece of raw beef rib elicited clearly aggressive behaviour among littermates. In Experiment 2 the food stimuli were chosen to differ from raw beef rib in various combinations of taste/smell, texture and monopolizability. Kittens showed different levels of aggression in response to the five stimuli tested, which suggests that the strong effect of beef rib in eliciting aggressive behaviour was due to a complex combination of features. We suggest that using stimuli approximating the evolved, functional significance to the species concerned is more likely to result in robust, biologically relevant behaviours than more artificial stimuli. PMID- 29454645 TI - Characterization of CD4+ T cell-mediated cytotoxicity in patients with multiple myeloma. AB - Multiple myeloma (MM) is an incurable cancer characterized by the development of malignant plasma cells. The CD8 T cell-mediated cytotoxicity is considered a major player in antitumor immunity, but in MM patients, the CD8 T cells displayed senescence markers and were functionally impaired. To investigate whether cytotoxic CD4 T cells could act as a treatment alternative in MM, we examined the frequency and function of naturally occurring cytotoxic CD4 T cells in MM patients. The cytotoxic CD4 T cells were identified as granzyme-A, granzyme B-, and perforin-expressing CD4 T cells, and their frequencies were significantly upregulated in MM patients when compared with healthy controls. The frequencies of cytotoxic CD4 T cells in MM patients were not associated with the frequencies of cytotoxic CD8 T cells, but were negatively associated with disease severity. Interestingly, the expression levels of inhibitory molecules, including PD-1 and CTLA-4, were significantly lower in cytotoxic CD4 T cells than in cytotoxic CD8 T cells. When co-incubated with autologous CD38+CD138+ plasma cells, CD4 T cells were capable of eliminating plasma cells with varying degrees of efficacy. In MM patients, the frequency of circulating plasma cells was negatively correlated with the frequency of cytotoxic CD4 T cells. Therefore, CD4 T cell-mediated cytotoxicity existed naturally in MM patients and could potentially act as an option in antitumor therapies.

AB - The profound deficiency of Th17 cells contributes to HIV disease progression. The mechanisms of their perturbation remain unclear. Recently, CCR6+CD95+CD4+ naive T cells (CCR6+CD95+CD4+ TNA), identified as pre-committed Th17 precursors, were recognized as a subpopulation of CD4+ T cells with stem cell properties. Following phenotypical identification, we evaluated their level in patients during chronic HIV infection and following antiretroviral therapy (ART) using flow cytometry. The levels of CCR6+CD95+CD4+ TNA were decreased during chronic HIV infection and correlated with CD4+ T cell counts. Immunological responders harbored higher frequency of CCR6+CD95+CD4+ TNA, which was associated with CD4/CD8 T cell ratio. Immunological non-responders with lower frequency of CCR6+CD95+CD4+ TNA failed to exhibit a correlation between CCR6+CD95+CD4+ TNA and CCR6+CD95+CD4+ TCM, and displayed elevated ratio of CCR6+CD95+CD4+ TCM/TNA. The number of CCR6+CD95+CD4+ TNA was increased following early ART. These findings shed light on the importance of targeting pre-committed Th17 precursors that enhance immune reconstitution. PMID- 29454647 TI - Dynamic plasticity of macrophage functions in diseased liver. AB - Liver macrophages attract increasing interest due to their crucial roles in homeostasis and hepatic diseases. Recent findings in mice and man suggest a remarkable phenotypic and functional diversity of liver macrophages. Kupffer cells, the subset of tissue resident macrophages with sentinel functions in liver, mainly arise from embryogenic precursors, whereas in injury, liver tissue is engrafted by monocyte-derived macrophages. Both principal macrophage populations respond to local or systemic signals and have substantial effects on reduction as well as aggravation of hepatic diseases. Despite contrasting functions of heterogeneous macrophage subsets in disease progression and regression, they may provide promising targets for novel therapeutic interventions in hepatology. Areas of intense research include their multifaceted roles in metabolic diseases (non-alcoholic steatohepatitis, NASH), fibrosis or liver cancer (hepatocellular or cholangiocellular carcinoma, HCC or CCA). We discuss recent findings on the origin, diversity and functional plasticity of liver macrophages in homeostasis and hepatic disease conditions. PMID- 29454648 TI - FOXP3 renders activated human regulatory T cells resistant to restimulation induced cell death by suppressing SAP expression. AB - Restimulation-induced cell death (RICD) is an apoptotic program that regulates effector T cell expansion, triggered by repeated stimulation through the T cell receptor (TCR) in the presence of interleukin-2 (IL-2). Although CD4+ regulatory T cells (Tregs) consume IL-2 and experience frequent TCR stimulation, they are highly resistant to RICD. Resistance in Tregs is dependent on the forkhead box P3 (FOXP3) transcription factor, although the mechanism remains unclear. T cells from patients with X-linked lymphoproliferative disease (XLP-1), that lack the adaptor molecule SLAM-associated protein (SAP), are also resistant to RICD. Here we demonstrate that normal Tregs express very low levels of SAP compared to conventional T cells. FOXP3 reduces SAP expression by directly binding to and repressing the SH2D1A (SAP) promoter. Indeed, ectopic SAP expression restores RICD sensitivity in human FOXP3+ Tregs. Our findings illuminate the mechanism behind FOXP3-mediated RICD resistance in Tregs, providing new insight into their long-term persistence. PMID- 29454649 TI - Relationship between vectorcardiographic QRSarea, myocardial scar quantification, and response to cardiac resynchronization therapy. AB - PURPOSE: To investigate the relationship between vectorcardiography (VCG) and myocardial scar on cardiac magnetic resonance (CMR) imaging, and whether combining these metrics may improve cardiac resynchronization therapy (CRT) response prediction. METHODS: Thirty-three CRT patients were included. QRSarea, Tarea and QRSTarea were derived from the ECG-synthesized VCG. CMR parameters reflecting focal scar core (Scar2SD, Gray2SD) and diffuse fibrosis (pre-T1, extracellular volume [ECV]) were assessed. CRT response was defined as >=15% reduction in left ventricular end-systolic volume after six months' follow-up. RESULTS: VCG QRSarea, Tarea and QRSTarea inversely correlated with focal scar (R = -0.44--0.58 for Scar2SD, p <= 0.010), but not with diffuse fibrosis. Scar2SD, Gray2SD and QRSarea predicted CRT response with AUCs of 0.692 (p = 0.063), 0.759 (p = 0.012) and 0.737 (p = 0.022) respectively. A combined ROC-derived threshold for Scar2SD and QRSarea resulted in 92% CRT response rate for patients with large QRSarea and small Scar2SD or Gray2SD. CONCLUSION: QRSarea is inversely associated with focal scar on CMR. Incremental predictive value for CRT response is achieved by a combined CMR-QRSarea analysis.

PMID- 29454651 TI - Effects of Prophylactic Foscarnet on Human Herpesvirus-6 Reactivation and Encephalitis in Cord Blood Transplant Recipients: A Prospective Multicenter Trial with an Historical Control Group. AB - Cord blood transplantation (CBT) is a distinct risk factor for human herpesvirus 6 (HHV-6) reactivation and HHV-6 encephalitis. In a prospective multicenter trial we investigated the effects of prophylactic foscarnet (90 mg/kg i.v. infusion from days 7 to 27 after CBT) on the occurrence of HHV-6 reactivation, HHV-6 encephalitis, and acute graft-versus-host disease (aGVHD) in CBT recipients. Between 2014 and 2016, 57 patients were included in a foscarnet-prophylaxis group. Outcomes were compared with an historical control group who received CBT between 2010 and 2014 (standard-treatment group, n = 63). The cumulative incidence of high-level HHV-6 reactivation, defined as plasma HHV-6 DNA >= 104 copies/mL, at 60 days after CBT was significantly lower in the foscarnet prophylaxis group than in the standard-treatment group (18.3% versus 57.3%, P < .001). Multivariate analysis revealed that myeloablative preconditioning and standard treatment were significant risk factors for high-level HHV-6 reactivation. The cumulative incidence of HHV-6 encephalitis at 60 days after CBT was not different between the groups (foscarnet-prophylaxis group, 12.4%; standard-treatment group, 4.9%; P = .14). The cumulative incidences of grades II to IV and grades III to IV aGVHD at 60 days after CBT were not different between the groups (grades II to IV aGVHD: foscarnet-prophylaxis group, 42.0%; standard treatment group, 40.5%; P = .96; grades III to IV aGVHD: foscarnet-prophylaxis group, 14.5%; standard-treatment group, 14.5%; P = 1.00). In the setting of this study foscarnet significantly suppressed systemic HHV-6 reactivation in CBT recipients but failed to prevent the development of HHV-6 encephalitis. Suppression of HHV-6 reactivation by foscarnet did not show any effects against the incidence of aGVHD. PMID- 29454652 TI - Rapid one-step extraction method for the identification of molds using MALDI-TOF MS. AB - Matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) has revolutionized fungal identification. Previously, we developed a MALDI-TOF MS mold extraction procedure and comprehensive database. While MALDI TOF MS has become routine in a few laboratories, it has not yet become widespread. A major obstacle is the lack of a simple, reproducible and uniform protein extraction procedure. In this study, we developed and validated a rapid one-step protein extraction protocol for filamentous fungi. Excised molds were placed into tubes containing zirconia-silica beads and extraction solution without washing or ethanol inactivation steps. Extraction solutions containing different ratios of acetonitrile and formic acid were evaluated. Samples were then processed using a PowerLyzer high power bead based homogenizer and supernatants spotted for MALDI-TOF MS. The rapid method was evaluated prospectively and in parallel to our current mold extraction protocol for 3 months. Analysis of 106 clinical mold isolates resulted in an improved performance and a decrease in extraction time by 30 minutes to a total of 5 minutes of hands-on time. Acceptable identification scores (>= 2.00) were achieved for up to 63.0% of mold isolates by the rapid method compared with 52.8% of isolates by the current routine protocol. Score comparisons between duplicate spots showed higher reproducibility of the rapid method as compared to the routine method. The rapid extraction method allows efficient analysis of clinical mold isolates both in scheduled batch runs and on an in-demand basis while providing a simple starting platform for laboratories adopting MALDI-TOF MS for mold identification. PMID- 29454653 TI - Diagnostic yield of real-time polymerase chain reaction in the diagnosis of intrapartum maternal rectovaginal colonization by group B Streptococcus: a systematic review with meta-analysis. AB - Group B Streptococcus is the leading etiologic factor of neonatal sepsis. Intrapartum real-time polymerase chain reaction (RT-PCR) may allow faster and more accurate detection of maternal colonization. The aim of this study was to determine the sensitivity and specificity of RT-PCR when compared to the reference standard culture in selective broth media collected from rectovaginal tract from laboring women. We selected 15 studies that included 6368 women. Papers selection, data extraction, and quality assessment were carried out by two independent researchers. The prevalence of maternal colonization was 23.8% by RT PCR and 22.1% by culture. The meta-analysis demonstrated an RT-PCR sensitivity of 93.7% (CI 92.1-95.3), and specificity of 97.6% (CI 97.0-98.1). This result is above the cutoff point defined by the Centers for Disease Control and Prevention for clinical usefulness. In conclusion, RT-PCR for GBS screening in labor ward is a promising tool; however, further well-designed studies to justify its use are needed. PMID- 29454655 TI - Neurogenetic Approaches to Stress and Fear in Humans as Pathophysiological Mechanisms for Posttraumatic Stress Disorder. AB - In this review article, genetic variation associated with brain responses related to acute and chronic stress reactivity and fear learning in humans is presented as an important mechanism underlying posttraumatic stress disorder. We report that genes related to the regulation of the hypothalamic-pituitary-adrenal axis, as well as genes that modulate serotonergic, dopaminergic, and neuropeptidergic functions or plasticity, play a role in this context. The strong overlap of the genetic targets involved in stress and fear learning suggests that a dimensional and mechanistic model of the development of posttraumatic stress disorder based on these constructs is promising. Genome-wide genetic analyses on fear and stress mechanisms are scarce. So far, reliable replication is still lacking for most of the molecular genetic findings, and the proportion of explained variance is rather small. Further analysis of neurogenetic stress and fear learning needs to integrate data from animal and human studies. PMID- 29454654 TI - Invasive pulmonary aspergillosis and influenza co-infection in immunocompetent hosts: case reports and review of the literature. AB - Invasive pulmonary aspergillosis (IPA) is classically considered an illness of severely immunocompromised patients with limited host defenses. However, IPA has been reported in immunocompetent but critically ill patients. This report describes two fatal cases of pathologically confirmed IPA in patients with influenza in the intensive care unit. One patient had influenza B infection, whereas the other had influenza A H1N1. Both patients died despite broad-spectrum antimicrobials, mechanical ventilation, and vasopressor support. Microscopic and histologic postmortem examination confirmed IPA. Review of the English language and foreign literature indicates that galactomannan antigen testing and classic radiologic findings for IPA may not be reliable in immunocompetent patients. Respiratory cultures which grow Aspergillus species in critically ill patients, particularly those with underlying influenza infection, should not necessarily be disregarded as contaminants or colonizers. Further research is needed to better understand the immunological relationship between influenza and IPA for improved prevention and treatment of influenza and Aspergillus co-infections. PMID- 29454656 TI - Rhythm and orthopedics: The effect of music therapy in cast room procedures, a prospective clinical trial. AB - INTRODUCTION: Cast room procedures generally cause anxiety in patients. Anxiety complicates the procedure as well as increases the risk of a complication. Listening to music was found to be the safest and most common non-drug treatment method. The aim of this study is to evaluate the effect of listening to music on adult patients in cast room procedures. This study points out the relation between anxiety and anxiety relevant cardiac arrhythmia. MATERIALS AND METHODS: The study was performed on 199 patients with stable general condition, aged above 18. The patients were divided into two groups. Randomization method used in the study was coin flip. The first group (Group 1) listened to music during cast room procedures whereby the second group (Group 2) did not listen to music. Length of the procedure, complication, blood pressure and heart rate evaluations before and after the procedure, Visual Analogue Scale (VAS scores for pain), State-Trait Anxiety Inventory (STAI) anxiety score, patient satisfaction, willingness of the patient to repeat the procedure, P wave dispersion (Pd) and corrected QT interval dispersion (QTcd) as electrocardiographic arrhythmia predictors were evaluated. The Clinical Research Ethics Committee approval was obtained for this study. RESULTS: Significant difference was shown between the two groups for the following criteria: VAS scores (p = 0.005), anxiety scores (p = 0.032), processing time (p = 0.027), and QTcd values (p = 0.031). Patient satisfaction (p < 0.001) and willingness to repeat the procedure (p < 0.001) were higher for the group who listened to music. No significant difference in Pd values, blood pressure and heart rate was reported within the groups. CONCLUSION: Music therapy is a non-invasive, safe, nonpharmacologic, anxiolytic, and analgesic treatment. Music therapy should become standard protocol in cast room procedures. One of the most important achievements of this study was the fact that music decreases anxiety and anxiety-related cardiac arrhythmia. Therefore, conducting further prospective studies including high cardiac risk patients especially with arrhythmia is crucial. PMID- 29454657 TI - Monitoring brain neuronal activity with manipulation of cardiac events in a freely moving rat. AB - Behavioral and cognitive studies have demonstrated that brain functions are affected by the activity states of the peripheral organs, such as the cardiac and respiratory systems. However, detailed neurophysiological mechanisms underlying the body-brain interactions remain unknown. In this study, we developed a method for manipulating activity levels of the heart using direct cardiac stimulation and vagus nerve stimulation that can be combined with recording cerebral local field potentials using a microdrive system, electrocardiograms, electromyograms, in a freely moving rat. With this method, the electrical stimulation to the heart increases heart rates up to 14 Hz, whereas the vagus nerve stimulation decreases heart rates to 3 Hz. Transient electrical artifacts arising from the peripheral stimulation are not contaminated in cortical local field potential signals low pass filtered at 150 Hz and distinguishable from extracellular multiunit signals. The technique will contribute to understanding the neurophysiological correlate of mind-body associations in health and disease. PMID- 29454658 TI - Return to the Operating Room after Macular Surgery: IRIS Registry Analysis. AB - PURPOSE: To investigate the rate of return to the operating room after vitrectomy surgery to treat macular hole or epiretinal membrane. DESIGN: A retrospective registry cohort. PARTICIPANTS: Individuals receiving care in ophthalmology practices participating in the Academy IRIS (Intelligent Research in Sight) Registry. METHODS: Data from the IRIS Registry were analyzed for patients who underwent vitrectomy for macular holes or epiretinal membranes. Cases were identified by the combination of International Classification of Diseases, 9th revision code (362.54, 362.56) and a current procedural terminology (CPT) code for vitrectomy surgery between January 1, 2013 and June 30, 2017. MAIN OUTCOME MEASURES: The eyes that underwent additional eye surgery within 1 year after initial vitrectomy for macular hole or epiretinal membrane were identified, as was the nature of the additional procedures per CPT code. RESULTS: A total of 41 475 eyes underwent vitrectomy for macular hole and 73 219 eyes underwent vitrectomy for epiretinal membrane during the study period. In the macular hole group, 7573 had a second surgery within 1 year, and 2827 (6.8%) had a second surgery that was not cataract related. In the epiretinal membrane group, 12 433 had a second surgery within 1 year, 4022 (5.5%) of which were not cataract related. In the macular hole group, 4.6% of eyes returned to the operating room for another macular hole repair surgery, and 2.0% returned for retinal detachment repair. In the epiretinal membrane group, 1.4% returned for a second vitrectomy with membrane stripping, and 2.5% returned for retinal detachment repair. CONCLUSIONS: This registry-based study encompassed a large number of patients but was limited by the inaccessibility of some information and the potential for inaccurate medical records or coding, as it obtained data from multiple electronic health records entities. Excluding cataract surgery, approximately 6% of eyes that underwent vitrectomy to address macular hole or epiretinal membrane returned for a second ophthalmic procedure within a year. In the macular hole group, most secondary non-cataract surgeries were for another macular hole repair procedure. For both macular holes and epiretinal membranes, approximately 2% of eyes required retinal detachment repair surgery within 1 year. PMID- 29454659 TI - Predicting Visual Acuity by Using Machine Learning in Patients Treated for Neovascular Age-Related Macular Degeneration. AB - PURPOSE: To predict, by using machine learning, visual acuity (VA) at 3 and 12 months in patients with neovascular age-related macular degeneration (AMD) after initial upload of 3 anti-vascular endothelial growth factor (VEGF) injections. DESIGN: Database study. PARTICIPANTS: For the 3-month VA forecast, 653 patients (379 female) with 738 eyes and an average age of 74.1 years were included. The baseline VA before the first injection was 0.54 logarithm of the minimum angle of resolution (logMAR) (+/-0.39). A total of 456 of these patients (270 female, 508 eyes, average age: 74.2 years) had sufficient follow-up data to be included for a 12-month VA prediction. The baseline VA before the first injection was 0.56 logMAR (+/-0.42). METHODS: Five different machine-learning algorithms (AdaBoost.R2, Gradient Boosting, Random Forests, Extremely Randomized Trees, and Lasso) were used to predict VA in patients with neovascular AMD after treatment with 3 anti-VEGF injections. Clinical data features came from a data warehouse (DW) containing electronic medical records (41 features, e.g., VA) and measurement features from OCT (124 features, e.g., central retinal thickness). The VA of patient eyes excluded from machine learning was predicted and compared with the ground truth, namely, the actual VA of these patients as recorded in the DW. MAIN OUTCOME MEASURES: Difference in logMAR VA after 3 and 12 months upload phase between prediction and ground truth as defined. RESULTS: For the 3-month VA forecast, the difference between the prediction and ground truth was between 0.11 logMAR (5.5 letters) mean absolute error (MAE)/0.14 logMAR (7 letters) root mean square error (RMSE) and 0.18 logMAR (9 letters) MAE/0.2 logMAR (10 letters) RMSE. For the 12-month VA forecast, the difference between the prediction and ground truth was between 0.16 logMAR (8 letters) MAE/0.2 logMAR (10 letters) RMSE and 0.22 logMAR (11 letters) MAE/0.26 logMAR (13 letters) RMSE. The best performing algorithm was the Lasso protocol. CONCLUSIONS: Machine learning allowed VA to be predicted for 3 months with a comparable result to VA measurement reliability. For a forecast after 12 months of therapy, VA prediction may help to encourage patients adhering to intravitreal therapy. PMID- 29454660 TI - Development and Course of Scars in the Comparison of Age-Related Macular Degeneration Treatments Trials. AB - PURPOSE: To describe risk factors for scar formation and changes to fibrotic scar through 5 years in the Comparison of Age-related Macular Degeneration Treatments Trials (CATT). DESIGN: Multicenter, prospective cohort study. PARTICIPANTS: A total of 1061 subjects in CATT. METHODS: Color photographic and fluorescein angiographic images from baseline and 1, 2, and 5 years were evaluated. Incidence of scar formation was estimated with Kaplan-Meier curves. Risk factors were assessed with Cox regression models. MAIN OUTCOME MEASURES: Scar formation, fibrotic scar area, and macular atrophy associated with fibrotic scar ("atrophy"). RESULTS: Cumulative proportion of eyes with scar was 32%, 46%, and 56% at years 1, 2, and 5, respectively. Baseline factors associated with increased risk (adjusted hazards ratio [aHR] and 95% confidence interval [CI]) were classic choroidal neovascularization (CNV) (aHR, 4.49; 95% CI, 3.34-6.04) versus occult, hemorrhage >1 disc area (DA) (aHR, 2.28; 95% CI, 1.49-3.47) versus no hemorrhage, retinal thickness >212 MUm (aHR, 2.58; 95% CI, 1.69-3.94) versus <120 MUm, subretinal tissue complex thickness >275 MUm (aHR, 2.64; 95% CI, 1.81 3.84) versus <=75 MUm, subretinal fluid thickness >25 MUm (aHR, 1.31; 95% CI, 0.97-1.75) versus no fluid, visual acuity (VA) in fellow eye 20/20 (aHR, 1.72; 95% CI, 1.25-2.36) versus 20/50 or worse, retinal pigment epithelium elevation absence (aHR, 1.71; 95% CI, 1.21-2.41), and subretinal hyperreflective material (aHR, 1.72; 95% CI, 1.25-2.36). Among 68 eyes that developed fibrotic scar at year 1, VA decreased by a mean of additional 13 letters between years 1 and 5. Mean scar area was 1.2, 1.2, and 1.9 DA at 1, 2, and 5 years, respectively. Atrophy was present in 18%, 24%, and 54% of these eyes at years 1, 2, and 5, respectively; the mean areas were 1.6, 2.0, and 3.1 DA, respectively. Atrophy replaced fibrotic scar in 8 eyes at year 5. There was no significant correlation between scar growth and atrophy growth. The rate of growth for both was similar between the clinical trial and observation periods. CONCLUSIONS: Several morphologic features, including classic CNV and large hemorrhage, are associated with scar formation. Rate of new scar formation declined after 2 years. Most fibrotic scars and accompanying macular atrophy expanded over time, reducing VA. PMID- 29454662 TI - Fecal markers of intestinal inflammation and intestinal permeability are elevated in Parkinson's disease. AB - BACKGROUND/OBJECTIVE: Intestinal inflammation and increased intestinal permeability (both possibly fueled by dysbiosis) have been suggested to be implicated in the multifactorial pathogenesis of Parkinson's disease (PD). The objective of the current study was to investigate whether fecal markers of inflammation and impaired intestinal barrier function corroborate this pathogenic aspect of PD. METHODS: In a case-control study, we quantitatively analyzed established fecal markers of intestinal inflammation (calprotectin and lactoferrin) and fecal markers of intestinal permeability (alpha-1-antitrypsin and zonulin) in PD patients (n = 34) and controls (n = 28, group-matched for age) by enzyme-linked immunosorbent assay. The study design controlled for potential confounding factors. RESULTS: Calprotectin, a fecal marker of intestinal inflammation, and two fecal markers of increased intestinal permeability (alpha-1 antitrypsin and zonulin) were significantly elevated in PD patients compared to age-matched controls. Lactoferrin, as a second fecal marker of intestinal inflammation, showed a non-significant trend towards elevated concentrations in PD patients. None of the four fecal markers correlated with disease severity, PD subtype, dopaminergic therapy, or presence of constipation. CONCLUSIONS: Fecal markers reflecting intestinal inflammation and increased intestinal permeability have been primarily investigated in inflammatory bowel disease so far. Our data indicate that calprotectin, alpha-1-antitrypsin and zonulin could be useful non invasive markers in PD as well. Even though these markers are not disease specific, they corroborate the hypothesis of an intestinal inflammation as contributing factor in the pathogenesis of PD. Further investigations are needed to determine whether calprotectin, alpha-1-antitrypsin and zonulin can be used to define PD subgroups and to monitor the effect of interventions in PD. PMID- 29454663 TI - Novel PLA2G6 mutations and clinical heterogeneity in Chinese cases with phospholipase A2-associated neurodegeneration. AB - INTRODUCTION: Phospholipase A2-associated neurodegeneration (PLAN) is an autosomal recessive movement disorder with abnormal iron deposition in basal ganglia, substantial nigra and adjacent areas, and cerebellar atrophy. It is caused by PLA2G6 mutations and comprises three phenotypes. We aimed to investigate genetic mutations in patients with predominantly extrapyramidal symptoms. METHODS: Eighteen Chinese patients with early onset of extrapyramidal symptoms were identified and underwent targeted next-generation sequencing, followed by Sanger sequencing. Detailed clinical and radiological features are presented. Prediction software was used to evaluate the pathogenicity of the identified variants. RESULTS: We identified 7 PLA2G6 variants including five known variants (c.668C > T, c.991G > T, c.1117G > A, c.1982C > T, and c.2218G > A) and two novel variants (c.1511C > T, and c.1915G > A) in four index cases. Among them, three cases had initial symptoms of difficulty walking or gait disturbance around the age of 30, and one case and his sibling developed mental handicap at age 7. Two cases exhibited a phenotype of "early parkinsonism" and the other two cases mimicked a phenotype of "hereditary spastic paraplegia (HSP)". Iron deposition in globus pallidus and substantia nigra was seen in three cases. Cerebellar atrophy was present in all four cases. CONCLUSIONS: Our study expands the mutation spectrum of the PLA2G6 gene and further supports the hypothesis that PLA2G6 mutations are associated with a continuous clinical spectrum from PLAN to HSP. PMID- 29454664 TI - Survey of midwives' perinatal mental health knowledge, confidence, attitudes and learning needs. AB - BACKGROUND: Midwives have a primary role in facilitating the first stage of perinatal mental health risk reduction through inquiring about perinatal mental health, identifying risk factors and current perinatal mental health problems, providing support or crisis intervention, referring for treatment and decreasing stigmatisation. AIMS: The aims of this study were to determine midwives' (a) knowledge of and confidence to identify and manage perinatal mental health problems, (b) attitudes towards women who experience severe mental illness and (c) perceived learning needs. DESIGN: A cross-sectional survey design. METHODS: The study was conducted between September 2016 and April 2017 in seven Maternity services in the Republic of Ireland with a purposeful non-random convenience sample of midwives (n=157). Data was anonymously collected utilising the Perinatal Mental Health Questionnaire, the Mental Illness: Clinician's Attitudes scale and the Perinatal Mental Health Learning Needs questionnaire. FINDINGS: Midwives indicated high levels of knowledge (71.1%) and confidence (72%) in identifying women who experience depression and anxiety however, they reported less confidence in caring (43.9%) for women. Only 17.8% (n=28) of midwives felt equipped to support women whilst 15.3% (n=24) reported having access to sufficient information. Midwives desire education on the spectrum of perinatal mental health problems. The mean score for the Mental Illness: Clinician's Attitudes scale was 36.31 (SD=7.60), indicating positive attitudes towards women with severe mental illness. CONCLUSION: Midwives require further education on perinatal mental health across cultures with a skill focus and which explores attitudes delivered in a study day format. PMID- 29454661 TI - Rethinking Phagocytes: Clues from the Retina and Testes. AB - Specialized phagocytes are a newly appreciated classification of phagocyte that currently encompasses Sertoli cells (SCs) of the testes and the retinal pigment epithelial cells (RPE) of the retina. While these cells support very different tissues, they have a striking degree of similarity both as phagocytes and in ways that go beyond cell clearance. The clearance of apoptotic germ cells, cell debris, and used photoreceptor outer segments are critical functions of these cells, and the unique nature of their clearance events make specialized phagocytes uniquely suited for studying the larger implications of cell clearance in vivo. The shared functions of specialized phagocytes could provide novel insights into how phagocytosis impacts tissue homeostasis and immune modulation. In this review, we examine the remarkable similarities between SCs and RPE as specialized phagocytes and the physiological effects of cell clearance within a tissue.

AB - BACKGROUND: In the 1990s, the Indonesian government launched programmes to train traditional birth attendants (TBAs) and increase the number of midwives. AIM: To identify and compare the factors that influence women's choice of a midwife or a TBA for maternal healthcare in Indonesia. METHODS: This study used a descriptive design for comparing women's choice of maternal healthcare. The participants were (1) married women, (2) experienced birth within two years, (3) living in a rural or urban village, and (4) capable of communicating in the Indonesia language. Three instruments were used: (1) traditional belief questionnaire, (2) preference for caregiver questionnaire, and (3) women-centered care (WCC) questionnaire which measured women's perceptions of care that they received during pregnancy. FINDINGS: A total of 371 women participated in this study. All these subjects answered based on their most recent birth within the last two years. Of the 371 women, 207 (55.8%) chose a midwife and 164 (44.2%) chose a TBA for giving birth. Women choosing midwives were generally satisfied and perceived receiving WCC. Factors determining choice were (1) women's background, (2) perception of WCC, (3) satisfaction, (4) choice of antenatal care (ANC), (5) family encouragement, and (6) traditional beliefs. DISCUSSION: The choice of caregivers was determined by not only education, parity, usual source of healthcare payment, and family encouragement but also traditional beliefs. CONCLUSION: Indonesian women's choice of a midwife instead of a TBA for their maternal healthcare resulted in a higher satisfaction of care and more ANC visits.

AB - BACKGROUND: Right atrial (RA) enlargement is a common finding in patients with pulmonary arterial hypertension (PAH) and an important predictor of mortality, however its relation to the risk of atrial arrhythmias has not been assessed. OBJECTIVES: To assess whether RA enlargement is associated with supraventricular arrhythmias (SVA) and whether it predicts new clinically significant SVA (csSVA). METHODS: Patients with PAH were recruited between January 2010 and December 2014 and followed until January 2017. csSVA was diagnosed if it resulted in hospitalization. To assess predictors of new csSVA, only patients without a history of SVA at baseline were analyzed. RESULTS: Among 97 patients, any SVA was observed in 45 (46.4%) and included permanent atrial fibrillation(AF, n = 8), paroxysmal AF (n = 10), permanent atrial flutter (AFl, n = 1), paroxysmal AFl (n = 2) or other types of supraventricular tachycardia (n = 24). Patients with SVA as compared to patients without SVA were characterized by older age, lower distance in a 6-minute test, higher NT-proBNP, higher RA area index (RAai), left atrial area index, mean right atrial pressure (mRAP) and were more commonly treated with beta-blocker. Eighty five patients who were in sinus rhythm at baseline assessment and had no history of significant SVA were observed for 37 +/ 19.9 months. During that time csSVA occurred in 15.3%. In univariate models, the occurrence of csSVA were predicted by age, right ventricular ejection fraction, right ventricular end diastolic index, RAai and mRAP, but in multivariate model only RAai remained significant predictor for csSVA (HR of 1.23, 95%CI: 1.11-1.36, p < 0.001). The optimal threshold for RA enlargement as discriminator of csSVA was 21.7 cm2/m2. CONCLUSIONS: In PAH patients RA enlargement is associated with increased prevalence of SVA. RAai is an independent predictor of hospitalization due to csSVA. PMID- 29454668 TI - High level production of a recombinant acid stable exoinulinase from Aspergillus kawachii. AB - Exoinulinases-enzymes extensively studied in recent decades because of their industrial applications-need to be produced in suitable quantities in order to meet production demands. We describe here the production of an acid-stable recombinant inulinase from Aspergillus kawachii in the Pichia pastoris system and the recombinant enzyme's biochemical characteristics and potential application to industrial processes. After an appropriate cloning strategy, this genetically engineered inulinase was successfully overproduced in fed-batch fermentations, reaching up to 840 U/ml after a 72-h cultivation. The protein, purified to homogeneity by chromatographic techniques, was obtained at a 42% yield. The following biochemical characteristics were determined: the enzyme had an optimal pH of 3, was stable for at least 3 h at 55 degrees C, and was inhibited in catalytic activity almost completely by Hg+2. The respective Km and Vmax for the recombinant inulinase with inulin as substrate were 1.35 mM and 2673 MUmol/min/mg. The recombinant enzyme is an exoinulinase but also possesses synthetic activity (i. e., fructosyl transferase). The high level of production of this recombinant plus its relevant biochemical properties would argue that the process presented here is a possible recourse for industrial applications in carbohydrate processing. PMID- 29454667 TI - PTEN expression in astrocytic processes after spinal cord injury. AB - The role of the Rho/ROCK/PTEN signaling pathway in the regulation of astrocyte function for consolidation/stabilization of the synapse has not been thoroughly studied. In this study, the expression of phosphatase and tensin homolog deleted on chromosome 10 (PTEN) in GFAP-positive astrocytic processes in the ventral horns (VH) of the rat spinal cord has been evaluated in the normal condition and in a delayed period (30 days) after dosed contusion spinal cord injury (SCI) in caudal thoracic segments. In intact rats and at 30 days post-injury (dpi), semi quantitative immunohistochemical analysis showed that there is approximately 2 folds less synaptophysin reactivity in the motoneuron perikarya than outside the perikarya, i.e., on dendritic spines, in the VH area. At 30 dpi, the square occupied by synaptophysin reactivity on the motoneuron perikarya and dendritic spines decreased ~2.4 and ~2.1 folds, respectively. Western blotting of the postsynaptic density protein 95 (PSD95) showed a decreased amount in the area of injury of ~3 folds at 30 dpi. Expression of GFAP in the astrocytic processes around the synaptophysin spots (APAS) was less than in the astrocytic processes that were located at distance from the synapses (APFS) both in the intact and SCI groups. In the APAS, the expression level of PTEN increased significantly after SCI. In these astrocytic processes, the PTEN expression level was significantly higher than in the APFS for both the intact and SCI rats. In the intact spinal cord, different PTEN expression levels were detected both in APAS and APFS. This may be due to the varying degree of integration of PTEN in the membrane compartment of astrocyte stem processes and possibly the increased delivery of PTEN from the GFAP-positive stem into fine GFAP-negative peripheral processes. The observed shifts after SCI reflect the imbalance in the mechanisms of synaptic plasticity after injury. Thus, strategies that have been developed for the deletion or knockdown of the PTEN gene are quite promising. PMID- 29454669 TI - Rabbits and the Specious Origins of Domestication. AB - Rabbits are commonly thought to have been domesticated in ~AD600 by French monks. Using historical and archaeological records, and genetic methods, we demonstrate that this is a misconception and the general inability to date domestication stems from both methodological biases and the lack of appreciation of domestication as a continuum. PMID- 29454670 TI - Ultrasonography and detection of subclinical joints and tendons involvements in Systemic Lupus erythematosus (SLE) patients: A cross-sectional multicenter study. AB - OBJECTIVES: The aims of this study in SLE population were (1) to describe ultrasonography (US) joint abnormalities, (2) to estimate the reliability of clinical swollen joint count (C-SJC) and SLEDAI (C-SLEDAI) versus US-SJC and US SLEDAI scores, (3) to highlight specific patterns of lupus patients with Power Doppler (PD) abnormalities. METHOD: For this cross-sectional multicenter study, 151 consecutive adult SLE patients were recruited. Evaluation included a clinical standardized joint assessment, B-mode and PD US of 40 joints and 26 tendons blinded for clinical examination. Reliability and agreement between clinical and B-mode US were calculated using the intraclass correlation coefficients (ICC [95% Confidence Interval]). RESULTS: We found a very high frequency of subclinical US abnormalities in asymptomatic patients: 85% of patients without joint symptoms had at least 1 US abnormality. Among them 46 patients (87%) had a history of joint involvement. The most frequent abnormalities were joint effusmaions (108 patients), synovial hypertrophy (SH, 109 patients) and synovitis (61 patients). Joint or tendon PD signal (grade>1) was found in 44% of patients (67/151). Synovitis were mainly located especially on MCPs and wrists. Even if reliability between clinical and grey-scale US SJC assessments was poor, reliability between clinical and US SLEDAI was good. Comparison between SLE patients with and without PD signal did not show any specific SLE pattern. CONCLUSION: US may be useful to assess joint involvement in SLE patients but did not significantly change SLEDAI score.

AB - Immune cells have a known role in pronociception, since they release a myriad of inflammatory algogens which interact with neurons to facilitate pain signaling. However, these cells also produce endogenous opioid peptides with analgesic potential. The sigma-1 receptor is a ligand-operated chaperone that modulates neurotransmission by interacting with multiple protein partners, including the MU opioid receptor. We recently found that sigma-1 antagonists are able to induce opioid analgesia by enhancing the action of endogenous opioid peptides of immune origin during inflammation. This opioid analgesia is seen only at the inflamed site, where immune cells naturally accumulate. In this article we review the difficulties of targeting the opioid system for selective pain relief, and discuss the dual role of immune cells in pain and analgesia. Our discussion creates perspectives for possible novel therapeutic uses of sigma-1 antagonists as agents able to maximize the analgesic potential of the immune system. PMID- 29454676 TI - OPA1: How much do we know to approach therapy? AB - OPA1 is a GTPase that controls several functions, such as mitochondrial dynamics and energetics, mtDNA maintenance and cristae integrity. In the last years, there have been described other cellular pathways and mechanisms involving OPA1 directly or through its interaction. All this new information, by implementing our knowledge on OPA1 is instrumental to elucidating the pathogenic mechanisms of OPA1 mutations. Indeed, these are associated with dominant optic atrophy (DOA), one of the most common inherited optic neuropathies, and with an increasing number of heterogeneous neurodegenerative disorders. In this review, we overview all recent findings on OPA1 protein functions, on its dysfunction and related clinical phenotypes, focusing on the current therapeutic options and future perspectives to treat DOA and the other associated neurological disorders due to OPA1 mutations. PMID- 29454677 TI - Saturated fatty acids and mortality in patients referred for coronary angiography The Ludwigshafen Risk and Cardiovascular Health study. AB - BACKGROUND: Saturated fatty acids are thought to be harmful by increasing the risk for cardiovascular events. OBJECTIVE: We examined the associations of erythrocyte saturated fatty acids with total and cardiovascular mortality in patients referred for coronary angiography. METHODS: Red blood cell saturated fatty acid (RBC SFA) proportions were measured by gas chromatography at baseline in 3259 participants of the Ludwigshafen Risk and Cardiovascular Health study. Associations of saturated fatty acid concentrations with mortality were investigated using Cox proportional hazards regression. RESULTS: During a median follow-up of 9.9 years, 975 patients (29.9%) died and 614 patients (18.8%) died of cardiovascular causes. The proportion of palmitic acid (PA, C16:0) ranged from 15.1% to 27.4% with a mean (standard deviation) of 21.9% (1.15%) and was associated with an increased risk for mortality in models adjusted for conventional cardiovascular risk factors. An increase of 1-standard deviation in PA was associated with a hazard ratio (95% confidence interval) of 1.08 (1.01 1.16) for all cause and 1.05 (0.96-1.15) for cardiovascular mortality after adjustment for cardiovascular risk factors. For the other investigated RBC SFA (C14:0, C18:0, C20:0, C22:0, and C24:0), there was no association with mortality and also not for the sum of all saturated fatty acids. CONCLUSIONS: Our results reveal association with increased mortality risk only for PA but not for the other RBC SFAs or the sum of all RBC SFAs and emphasize the need to investigate each fatty acid individually rather than studying groups of fatty acids. PMID- 29454678 TI - Treatment of coenzyme Q10 for 24 weeks improves lipid and glycemic profile in dyslipidemic individuals. AB - BACKGROUND: The use of coenzyme Q10 (CoQ10) as an adjuvant treatment with routine clinical therapy against metabolic diseases has shown benefit. However, the effect of CoQ10 as a primary preventive agent against cardiovascular diseases (CVDs) has not been well studied. OBJECTIVE: The objective of this study was to investigate the effect of CoQ10 on CVD risk factors in dyslipidemic patients. METHODS: In this randomized, double-blinded, placebo-controlled trial, 101 dyslipidemic subjects without taking any hypoglycemic or hypolipidemic drugs were administrated to 120 mg CoQ10 or placebo daily for 24 weeks. Anthropometric parameters, lipid and glycemic profile, biomarkers of inflammation, and antioxidant capacity were evaluated before and after 12 and 24 weeks of intervention. RESULTS: All 101 subjects were included in the analysis. On the 12th week, compared to placebo, CoQ10 supplementation decreased systolic (P = .010) and diastolic pressure (P = .001) and increased serum total antioxidant capacity (TAC; P = .003). On the 24th week, compared to placebo, CoQ10 supplementation further lowered blood pressure and TAC, reduced triglyceride (P = .020) and low-density lipoprotein cholesterol (P = .016), and increased ApoA-I (P < .001) while decreasing homeostasis model assessment of insulin resistance index (P = .009). Adjustment for change of physical activity and energy intake did not alter the effect of CoQ10 on the aforementioned parameters but led to significant decrease of non-high-density lipoprotein cholesterol in CoQ10 group compared to placebo (P = .031). CONCLUSIONS: Twenty-four-week treatment of CoQ10 ameliorates multiple CVD risk factors. The versatility and safety of CoQ10 makes it a potential candidate for the primary prevention of CVD. PMID- 29454679 TI - The prevalence and etiology of extreme hypertriglyceridemia in children: Data from a tertiary children's hospital. AB - BACKGROUND: Extreme hypertriglyceridemia (eHTG; serum triglycerides >= 2000 mg/dL) poses a significant risk for acute pancreatitis. There is paucity of data regarding the prevalence and etiology of eHTG in children. OBJECTIVE: To determine the prevalence, clinical features and etiologies of patients with eHTG at a tertiary children's hospital in the United States and in the United States National Health and Nutrition Examination Survey (NHANES). METHODS: A retrospective analysis was conducted of the electronic medical records of the Children's Medical Center, Dallas, from 2000-2015, and the NHANES data from 2005 2014 for eHTG. RESULTS: Of 30,623 children, 36 (~ 1 in 1000) had eHTG and one third of them developed acute pancreatitis. They tended to be female (61%), Hispanic (39%), and nonobese (median body mass index z-score 1.60 and 1.25 in males and females, respectively). Most patients had secondary causes such as uncontrolled diabetes mellitus (30%), L-asparaginase and high-dose corticosteroid therapy for acute lymphoblastic leukemia (28%), and sirolimus/tacrolimus therapy after solid organ transplantation (14%). Five patients (14%) had type 1 hyperlipoproteinemia (T1HLP; familial chylomicronemia syndrome). The NHANES data revealed that none of the 2362 children had eHTG, and the prevalence in adults was 0.02%. CONCLUSIONS: Extreme HTG is rare in children and majority of the children had secondary causes. Patients with diabetes mellitus or receiving drugs, such as, L-asparaginase, corticosteroids, and sirolimus, should be closely monitored for eHTG. Prevalence of T1HLP is approximately 1 in 6000 at a tertiary care center with an estimated population prevalence of 1 in 3,00,000. Early neonatal screening and intervention for T1HLP can prevent life-threatening morbidities such as acute pancreatitis. PMID- 29454680 TI - Cardiomyopathy in the pediatric patients. AB - Pediatric cardiomyopathies are a group of myocardial diseases with complex taxonomies. Cardiomyopathy can occur in children at any age, and it is a common cause of heart failure and heart transplantation in children. The incidence of pediatric cardiomyopathy is increasing with time. They may be associated with variable comorbidities, which are most often arrhythmia, heart failure, and sudden death. Medical imaging technologies, including echocardiography, cardiac magnetic resonance, and nuclear cardiology, are helpful in reaching a diagnosis of cardiomyopathy. Nevertheless, endomyocardial biopsy is the final diagnostic method of diagnosis. Patients warrant surgical operations, such as palliative operations, bridging operations, ventricular septal maneuvers, and heart transplantation, if pharmaceutical therapies are ineffective. Individual therapeutic regimens due to pediatric characteristics, genetic factors, and pathogenesis may improve the effects of treatment and patients' survival. PMID- 29454681 TI - Male Breast Magnetic Resonance Imaging: When is it Helpful? Our Experience Over the Last Decade. AB - Currently, there are no clear indications or guidelines for performing breast magnetic resonance imaging (MRI) in male patients diagnosed with primary breast cancer. The literature is also very limited on the usage of breast MRI in male patients. Although it is not common or recommended as a routine clinical practice to perform breast MRI in male patients even in the setting of a diagnosis of breast cancer, there are few instances where MRI may help clinicians and surgeons. With a comprehensive review of cases that was performed at our institution over the last 10 years, the readers may achieve better understanding of when it may be helpful to perform breast MRI in male patients. PMID- 29454682 TI - Short communication: Genetic lag represents commercial herd genetic merit more accurately than the 4-path selection model. AB - Expectation of genetic merit in commercial dairy herds is routinely estimated using a 4-path genetic selection model that was derived for a closed population, but commercial herds using artificial insemination sires are not closed. The 4 path model also predicts a higher rate of genetic progress in elite herds that provide artificial insemination sires than in commercial herds that use such sires, which counters other theoretical assumptions and observations of realized genetic responses. The aim of this work is to clarify whether genetic merit in commercial herds is more accurately reflected under the assumptions of the 4-path genetic response formula or by a genetic lag formula. We demonstrate by tracing the transmission of genetic merit from parents to offspring that the rate of genetic progress in commercial dairy farms is expected to be the same as that in the genetic nucleus. The lag in genetic merit between the nucleus and commercial farms is a function of sire and dam generation interval, the rate of genetic progress in elite artificial insemination herds, and genetic merit of sires and dams. To predict how strategies such as the use of young versus daughter-proven sires, culling heifers following genomic testing, or selective use of sexed semen will alter genetic merit in commercial herds, genetic merit expectations for commercial herds should be modeled using genetic lag expectations. PMID- 29454683 TI - Short communication: Heritability of twinning rate in Holstein cattle. AB - Multiple births or twinning in cattle is a naturally occurring reproductive phenomenon. For dairy cattle, twinning is considered a detrimental trait as it can be harmful to cow and calf as well as costly to the producer. The objective of this study was to examine recent US calving records for the Holstein breed to determine a current estimate of heritability for twinning rate along with effects of season and parity. Two models were used in this study: a linear sire model and a binary threshold-logit sire model. Both were mixed models considering fixed effects and random effects. Analyses were conducted using a restricted maximum likelihood method. Heritability estimates were 0.0192 +/- 0.0009 and 0.1420 +/- 0.0069 for the linear and threshold models, respectively. Repeatabilities from the linear and threshold-logit models were 0.0443 +/- 0.0012 and 0.2310 +/- 0.0072, respectively. The nonzero estimates of heritability indicate the potential to select against this trait for genetic improvement of Holstein cattle. PMID- 29454684 TI - Behavior and productivity of cows milked in automated systems before diagnosis of health disorders in early lactation. AB - Associations of electronically recorded data were examined before diagnosis of health disorders in early-lactation cows in herds with automated milking systems (AMS). Rumination time, activity, and milk yield data were collected for 8 mo for 605 early-lactation cows in 9 commercial AMS herds. Using multivariable generalized linear regression models controlling for parity and days in milk, data were examined relative to the day of diagnosis for health disorders occurring in absence of, or at least 14 d before, another disorder: mastitis (n = 13), new cases of lameness (n = 45), subclinical ketosis (SCK; n = 113), and purulent vaginal discharge (n = 49). All cases of displaced abomasum (DA; n = 8) occurred in conjunction with other disorders. Deviations from baseline among affected cows were examined, as well as differences compared with a group of healthy cows and an average group of all cows, who were given mock diagnosis days using the mean days in milk at diagnosis for each disorder. On 6 to 14 d of the 2 wk before diagnosis, cows with DA or mastitis had lower milk yield, rumination time, milking frequency, activity, and milk temperature compared with healthy cows as well as deviations from their own baseline rumination time and milk data starting 4 to 12 d before diagnosis. Cows with DA had lower AMS supplement intake than healthy cows and deviations from their baseline activity and milk temperature starting 6 and 4 d before diagnosis, respectively. Cows with mastitis had greater milk conductivity than healthy cows and deviated from their baseline milking frequency and conductivity 8 and 12 d before diagnosis, respectively. Compared with healthy cows, those with SCK or new cases of lameness generally had lower milk yield, rumination time, milk temperature, supplement intake, and milking and refusal frequencies. Only the milk temperature of lame cows deviated from baseline. Thus, acute health disorders (i.e., DA and mastitis) were associated with deviations from those cows' baseline AMS data, whereas more chronic disorders (i.e., SCK and lameness) were associated with significant but subtle longer term changes in milk production and behavior. Because cows with health disorders deviated from a group of healthy cows before they deviated from their own baseline and from the average of all other cows, including a healthy reference group in health alerts could refine the ability of detection models to identify subtle deviations in early lactation. PMID- 29454685 TI - Genes involved in tolerance to osmotic stress by random mutagenesis in Cronobacter malonaticus. AB - Cronobacter malonaticus is one of the opportunistic food-borne pathogens in powdered infant formula and has unusual abilities to survive under environmental stresses such as osmotic conditions. However, the genes involved in osmotic stress have received little attention in C. malonaticus. Here, genes involved in osmotic stress were determined in C. malonaticus using a transposon mutagenesis approach. According to the growth of mutants (n = 215) under 5.0% NaCl concentration, the survival of 5 mutants under osmotic stress was significantly decreased compared with that of the wild type strain. Five mutating sites, including potassium efflux protein KefA, inner membrane protein YqjF, peptidylprolyl isomerase, Cys-tRNA(Pro)/Cys-tRNA(Cys) deacylase, and oligogalacturonate lyase were successfully identified. In addition, the biofilm formation of 5 mutants was determined using crystal violet staining, scanning electron microscopy, and confocal laser scanning microscopy, and the biofilms of 5 mutants significantly decreased within 72 h compared with that of wild type strain. This is the first report to determine the genes involved in osmotic tolerance in C. malonaticus. The findings provided valuable information for deep understanding of the mechanism of survival of C. malonaticus under osmotic stress, and a possible relationship between biofilm formation and tolerance to osmotic stress was also demonstrated in C. malonaticus. PMID- 29454686 TI - Differential effects of a single dose of oral calcium based on postpartum plasma calcium concentration in Holstein cows. AB - Our objectives were to determine (1) the effect of a single dose of an oral Ca bolus within 24 h after parturition on plasma Ca concentration, (2) the response of primiparous (PP) and multiparous (MP) cows to this supplementation strategy, and (3) differential responses based on plasma Ca at enrollment. For objective 1, cows from 1 commercial dairy in New York State were enrolled within 19 h after parturition (mean +/- standard deviation = 8.3 +/- 5.3 h) and randomized within parity group (first, second, and >=third) to control [CON (n = 25); no placebo] or a single dose bolus treatment [BOL (n = 25); 3 oral Ca boluses supplying 54 to 64 g of Ca]. Plasma Ca was measured repeatedly between 1 and 24 h following treatment. For objectives 2 and 3, cows on 6 commercial farms in New York State were assigned to treatment as for objective 1 (CON, n = 1,973; BOL, n = 1,976). Herd records for health, reproduction, and Dairy Herd Improvement Association test day milk production were collected. Mixed effect multivariable models were developed using repeated measures ANOVA, Poisson regression, or proportional hazard models. Objective 2 analyses considered treatment with periparturient risk factors, whereas objective 3 analyses also considered Ca status. No difference was observed for plasma Ca between 1 and 24 h after treatment. Primiparous cows assigned to BOL calving at >712 d old had decreased risk of one or more health disorders [<=30 d in milk; risk ratio (RR) = 0.65, 95% confidence interval (CI) = 0.51 to 0.84] and those with body condition score >3.5 responded to BOL with increased milk production (CON = 31.7 +/- 1.1, BOL = 35.1 +/- 1.1 kg/d), as did those with days carried calf >277 (CON = 31.9 +/- 1.0, BOL = 34.7 +/- 1.0 kg/d). Reduced risk of one or more health disorders was observed in parity >=3 (RR = 0.85, 95% CI = 0.81 to 0.89) and MP cows with body condition score >3.5 (retained placenta; RR = 0.70, 95% CI = 0.58 to 0.84) or that were lame (displaced abomasum; RR = 0.49, 95% CI = 0.32 to 0.75). Differential responses for PP cows by Ca status were minimal. For MP cows with low plasma Ca, BOL decreased risk of additional Ca treatment (<=1.8 mmol/L; RR = 0.57, 95% CI = 0.40 to 0.80) as well as risk of one or more health disorders (<=2.15 mmol/L; RR = 0.90, 95% CI = 0.85 to 0.95). Supplementation with a single oral dose of Ca could be targeted to periparturient risk groups for improved health. Calcium status did not differentiate responses of PP cows, but MP cows with low Ca at parturition had improved health status when supplemented. PMID- 29454687 TI - Bioeconomics of sexed semen utilization in a high-producing Holstein-Friesian dairy herd. AB - A bioeconomic, stochastic spreadsheet model, that included calculation of the net present value of the additional value of all future descendants resulting from increased selection intensity, was developed to study the profitability of using sexed semen in a high input-high output dairy herd. Three management strategies were modeled: (1) only heifers inseminated with sex-sorted semen and cows inseminated with unsorted semen; (2) both heifers and cows inseminated with sex sorted semen; and (3) a reference scenario, in which all breeding females were inseminated with unsorted semen. A Monte Carlo simulation (@risk software, Palisade Corp., Ithaca, NY) was run to study the sensitivity of net profit and sexed semen advantage to key input parameters. Most input parameters were given truncated normal distributions, whereas the maximum numbers of inseminations in heifers and cows were given discrete distribution functions. The calculated intensity of selection accounted for the different numbers of dairy females born for each of the 100,000 iterations. Using sexed semen (X-sorted, female) was shown to be profitable, with insemination of both heifers and cows being most profitable. The returns on assets were higher when only heifers were inseminated with sexed semen (8.54% +/- 2.94; +/-SD) or all females were inseminated with sexed semen (8.85% +/- 2.93) than when all females were inseminated with unsexed semen (8.38% +/- 2.95). The range in net profit was most sensitive to the assumed distributions of milk protein price (?/kg), milk fat price (?/kg), cow pregnancy rate, fertilizer price (?/t), and concentrate price (?/t) when unsorted semen was used. When only heifers or both heifers and cows were inseminated with sex-sorted semen, the range in net profit was most sensitive to the same distributions, with fertilizer price and cow pregnancy rate in reverse order of sensitivity. However, the range in sex-sorted semen advantage (in net profit) when only heifers were inseminated with sex-sorted semen was most sensitive to the assumed distributions of cow pregnancy rate, sex-sorted semen pregnancy rate as a percent of unsorted semen rates, standard deviation of index, additional cost of sex-sorted semen (?/dose), dairy bull calf price (?/head), and dairy heifer calf price (?/head). When both heifers and cows were inseminated, the order of importance of the last 2 inputs was reversed. This study highlights the relatively high effect of pregnancy rate and the genetic value of dairy bulls in determining the level of financial advantage from using sex-sorted semen in a dairy herd. PMID- 29454688 TI - Fermentation and aerobic stability of rehydrated corn grain silage treated with different doses of Lactobacillus buchneri or a combination of Lactobacillus plantarum and Pediococcus acidilactici. AB - We investigated the effects of different types and doses of inoculants for ensiling rehydrated corn grain. Shelled corn was finely ground and rehydrated to 35% moisture. Treatments were as follows: (1) control (no additives); (2) Lactobacillus plantarum and Pediococcus acidilactici (LPPA) at a theoretical application rate of 1 * 105 cfu/g; (3) LPPA at 5 * 105 cfu/g; (4) LPPA at 1 * 106 cfu/g; (5) Lactobacillus buchneri (LB) at 1 * 105 cfu/g; (6) LB at 5 * 105 cfu/g; and (7) LB at 1 * 106 cfu/g. We detected no effect of inoculant dose. Gas losses were greater in silages treated with LB compared with control and LPPA silages. Treating silages with LB reduced the concentrations of lactic acid and ethanol and increased silage pH and concentrations of acetic acid, propionic acid, and 1,2-propanediol. At silo opening, silages treated with LB had higher counts of lactic acid bacteria but lower yeast counts than the control silage. Aerobic stability was greater for silages treated with LB and lower for silages treated with LPPA compared with the control. The LB reduced dry matter (DM) losses during aerobic exposure, whereas LPPA increased them. Prolamin content was lower in silages treated with LB compared with the control, resulting in greater ruminal in situ DM degradability. Inoculating LB to a dose of 1 * 105 cfu/g increased aerobic stability and ruminal in situ DM degradability of rehydrated corn grain silage. The addition of LPPA did not alter the fermentation process and worsened the aerobic stability of rehydrated corn grain silage. Further studies are warranted to confirm these conclusions in other corn hybrids, inoculants, and their combinations. PMID- 29454689 TI - Southeast Asia's import demand for skim milk powder: Implications for US exporters. AB - Dairy industries in Southeast Asia are small and produce less than the domestic market demands. As expenditure and population grow in Southeast Asia, it is expected that the expenditures on skim milk powder (SMP) will grow. In this study, we examined the competitiveness of US SMP in the Southeast Asian market with respect to other leading dairy exporters, including the European Union (EU 28), New Zealand, and Australia. Using monthly data from 2006 to 2015, Rotterdam models were used to estimate import demands for SMP in 4 Southeast Asian countries. In a scenario using annual averages from 2013 to 2015 as a baseline, our findings suggest that a 10% reduction in the US price of SMP would cause Indonesia, Singapore, Vietnam, and the Philippines SMP imports from the United States to increase by 3.96, 0.44, 2.68, and 1.94 kt, respectively. Under the same scenario, the value of US SMP imports would decrease for Indonesia, Vietnam, and the Philippines by $4.12, $2.93, and $2.48 million, respectively; however, the value of US SMP to Singapore would increase by $0.20 million. Singapore and Indonesia expenditures for the US SMP are elastic, which means that as expenditure and population in Southeast Asia continue to grow, a 1% increase in SMP expenditure in Singapore and Indonesia would result in 1.25 and 1.20% increases in US SMP exports.

AB - Our aging population and the accompanying decline in immune function is a growing concern that may be addressed by finding natural methods to enhance the immunocompetence of our elderly. Bovine milk and colostrum from cows that have been immunized have been shown to provide additional immunoglobulins and other bioactive molecules that enhance immune function. The purpose of this study was to investigate the ability of hyperimmune bovine colostrum to alleviate the symptoms of rheumatoid arthritis in a murine model. The collagen-induced arthritis DBA/1J murine model was used for this study. Mice were fed colostrum from immunized cows at either 5 or 10 mg/mouse per day or controls for 49 d. The data showed that the colostrum-fed groups had significantly lower total swelling scores and significantly lower collagen-specific antibody (IgG2a), inflammation associated antibody (total IgG), and the inflammatory cytokines tumor necrosis factor alpha, IL-2, IL-6, and IFN-gamma. The results strongly suggest that colostrum from immunized cows may have anti-inflammatory activity in a mouse model of rheumatoid arthritis. PMID- 29454691 TI - The effect of alfalfa (Medicago sativa) silage chop length and inclusion rate within a total mixed ration on the ability of lactating dairy cows to cope with a short-term feed withholding and refeeding challenge. AB - The objectives of the study were (1) to test whether 6 h of feed deprivation followed by refeeding induces an acidosis challenge in dairy cattle and (2) to quantify the acidosis challenge mitigation potential of increased alfalfa silage concentration in the diet. Alfalfa silage constituted either 25 or 75% of forage dry matter (DM) replacing corn silage [low (LA) or high alfalfa (HA)] and was chopped to either 14 or 19 mm theoretical length [short (S) or long (L)]. Dietary treatments LAS, LAL, HAS, or HAL were offered to 4 rumen-cannulated Holstein dairy cattle (161 d in milk; 5th or 6th parity) in a 4 * 4 Latin square design study with 21-d periods. Starch concentration was 69 g/kg of DM higher for LA diets than HA diets. Feed was withheld for 6 h followed by ad libitum refeeding on d 18 of each period. Measurements of DM intake, milk yield and composition, rumen pH, and eating and rumination behavior were taken on 1 baseline day, the challenge day, and 2 further recovery days. After refeeding, rumen pH was reduced in cows fed LA diets but not HA diets. Feeding LAL resulted in the greatest subclinical acidosis risk (pH <5.8 for 355 min on the first recovery day). Animals fed LA produced 4.4 L less milk on the challenge day in comparison to baseline. It was concluded that short-term feed deprivation detrimentally affected rumen health and milk yield in dairy cattle normally fed ad libitum, but had no effect on DM intake or milk composition. Feeding alfalfa silage in place of corn silage mitigated acidosis risk due to interrupted feed supply, likely due to a combination of lower starch concentration in HA diets, greater effective fiber concentration, and higher buffering capacity of alfalfa relative to corn silage. PMID- 29454692 TI - From milk to cheese: Evolution of flavor fingerprint of milk, cream, curd, whey, ricotta, scotta, and ripened cheese obtained during summer Alpine pasture. AB - The role of each step of cheese and ricotta making in development of flavor of cheese and other dairy products is not yet well known. The objectives of this study were to characterize volatile organic compounds (VOC) in cheese and ricotta making with bulk milk from cows grazing in a highland area and to evaluate their evolution in the various dairy products and by-products obtained during the production processes. A group of 148 cows was grazed day and night on pasture from June to September. A total of 7 cheese-making sessions were carried out using the bulk milk collected every 2 wk during summer pasturing according to the artisanal procedure used for Malga cheese production. All milks, products, and by products were sampled, and the VOC content of milk, cream, whey, ricotta, scotta (residual liquid), fresh cheeses, and cheeses ripened for 6 and 12 mo was determined by solid-phase microextraction gas chromatography-mass spectrometry. Forty-nine compounds were identified belonging to the following chemical families: alcohols (13), aldehydes (9), esters (8), free fatty acids (6), ketones (5), lactones (2), sulfurs (2), terpenes (2), phenol (1), and benzene (1). The results showed that the amounts of VOC in the various dairy products differed significantly. Comparisons between the VOC of 4 types of milk (whole evening, skim evening, whole morning, mixed in the vat) showed that the skimming process had the greatest effect, with about half of all the VOC analyzed affected, followed by time of milking (evening milking vs. morning milking) and mixing (skim evening milk mixed with whole morning milk). In general, among fresh products, cream had higher contents of fatty acids, sulfurs, and terpene volatile compounds than fresh cheese and ricotta, whereas ricotta showed a very high VOC amount compared with fresh cheese, probably due to its high processing temperature. The effects of the progressive nutrient depletion in milk during processing were investigated by comparing the amounts of VOC in vat milk, whey, and scotta. Although milk contained greater amounts of nutrients, whey and especially scotta had higher concentrations of VOC, with the exception of esters, sulfurs, terpenes, and phenolic compounds, as a result of physicochemical and microbial modifications during processing. Finally, the effect of ripening was tested by comparing the VOC of fresh and ripened cheeses (6 and 12 mo), revealing that VOC release increased dramatically during the first semester and further with increasing the ripening period to 1 yr. In particular, some alcohols (butan 2-ol), aldehydes (2-methylpropanal, hexanal, and heptanal), esters (ethyl butanoate and ethyl hexanoate), fatty acids (acetic, butanoic, and hexanoic acids), and ketones (butan-2-one, pentan-2-one, and heptan-2-one) showed a very large increase. In conclusion, according to the artisanal milk processing carried out for Malga cheese production, the quantity of VOC was shown to increase about 3 times during cheese making (from milk in vat to fresh cheese plus whey), almost 4 times during ricotta making (from whey to ricotta plus scotta), and about 16 times during 1 yr of ripening of cheese. PMID- 29454693 TI - Mating strategies to maximize genetic merit in dairy cattle herds. AB - The genetic merit of a herd is a key determinant in productivity for dairy farmers. However, making breeding decisions to maximize the rate of genetic gain can be complex because there is no certainty about which cows will become pregnant with a heifer calf. In this study, breeding worth (BrW) was used as a measure of genetic merit, and several mating strategies were evaluated. These strategies included randomly mating whole herds to the entire bull team, excluding low-ranked cows from producing replacement heifers, and nominating high ranked cows to the most highly ranked bulls. Simulations were undertaken using 4 bull teams generated from bulls currently marketed in New Zealand and a selection of New Zealand dairy herds. Average replacement heifer BrW was calculated for 1,000 iterations of each combination of mating strategy, herd, and bull team (scenario). Variation in resulting average replacement heifer BrW within scenarios was due to random sampling of which cows became pregnant with a heifer calf. Relative to mating the whole herd to an entire bull team, excluding the lowest ranked cows from producing replacements resulted in the greatest increase in average replacement heifer BrW across all herds and bull teams, with a gain of approximately 0.4 BrW point for each 1% of cows excluded. Nominating top-ranking cows to the highest ranking bulls in the team had little effect (0.06-0.13 BrW increase for each 1% of top cows nominated) in improving BrW of replacement heifers. The number of top bulls nominated had a variable effect depending on the BrW spread of the entire bull team. Although excluding cows with the lowest BrW from producing replacement heifers is most effective for improving BrW, it is important to ensure that the number of heifers born is sufficient to replace cows leaving the herd. It is likely that optimal strategies for improving BrW will vary from farm to farm depending not only on the BrW structure of the herd, the bull team available, and the reproduction success on farm but also on farm management practices. This simulation study provides expected outcomes from a variety of mating strategies to allow informed decision making on farm. PMID- 29454694 TI - Milk losses associated with somatic cell counts by parity and stage of lactation. AB - The reduction of milk production caused by subclinical mastitis in dairy cows was evaluated through the regression of test-day milk yield on log-transformed somatic cell counts (LnSCC). Official test-day records (n = 1,688,054) of Holstein cows (n = 87,695) were obtained from 719 herds from January 2010 to December 2015. Editing was performed to ensure both reliability and consistency for the statistical analysis, and the final data set comprised 232,937 test-day records from 31,692 Holstein cows in 243 herds. A segmented regression was fitted to estimate the cutoff point in the LnSCC scale where milk yield started to be affected by mastitis. The statistical model used to explain daily milk yield included the effect of herd as a random effect and days in milk and LnSCC as fixed effects regressions, and analyses were performed by parity and stage of lactation. The cutoff point where milk yield starts to be affected by changes in LnSCC was estimated to be around 2.52 (the average of all estimates of approximately 12,400 cells/mL) for Holsteins cows from Brazilian herds. For first lactation cows, milk losses per unit increase of LnSCC had estimates around 0.68 kg/d in the beginning of the lactation [5 to 19 d in milk (DIM)], 0.55 kg/d in mid-lactation (110 to 124 DIM), and 0.97 kg/d at the end of the lactation (289 to 304 DIM). For second-lactation cows, milk losses per unit increase of LnSCC had estimates around 1.47 kg/d in the beginning of the lactation (5 to 19 DIM), 1.09 kg/d in mid-lactation (110 to 124 DIM), and 2.45 kg/d at the end of the lactation (289 to 304 DIM). For third-lactation cows, milk losses per unit increase of LnSCC had estimates around 2.22 kg/d in the beginning of the lactation (5 to 19 DIM), 1.13 kg/d in mid-lactation (140 to 154 DIM), and 2.65 kg/d at the end of the lactation (289 to 304 DIM). Daily milk losses caused by increased LnSCC were dependent on parity and stage of lactation, and these factors should be considered when estimating losses associated with subclinical mastitis. PMID- 29454695 TI - Short communication: Cholesterol oxidation products in traditional buttermilk. AB - The aim of this study was to quantitatively and qualitatively assess the content of cholesterol oxidation products in traditional buttermilk after butter production. Cholesterol oxidation products (COP) exhibit a wide spectrum of biological activity, including cytotoxic, carcinogenic, and pro-oxidative properties. Buttermilk has about 2 mg of COP/kg of fat, including 7beta hydroxycholesterol and 5,6alpha-epoxycholesterol. Buttermilk immediately after production had a relatively high level of 7beta-hydroxycholesterol (1.47 mg/kg), which decreased to 0.61 mg/kg after storage for 10 h at 3 degrees C. During storage, the content of 5,6alpha-epoxycholesterol increased from 0.50 to 1.40 mg/kg. After 10 h of storage, the antioxidant potential of the buttermilk decreased (expressed as radical scavenging ability; change in 1,1-diphenyl-2 picrylhydrazyl = 32.2%). This study showed the presence of COP in fresh and stored buttermilk and the influence of time on changing the direction of cholesterol oxidation. PMID- 29454696 TI - The effect of tube versus bottle feeding colostrum on immunoglobulin G absorption, abomasal emptying, and plasma hormone concentrations in newborn calves. AB - The objective of this study was to determine if feeding colostrum to newborn calves through an esophageal tube, compared with a nipple bottle, would delay abomasal emptying, which would in turn decrease passive transfer of IgG and plasma glucose, insulin, and glucagon-like peptide (GLP) 1 and GLP-2 concentrations. Twenty newborn Holstein bull calves were fed 3 L of colostrum replacer (200 g of IgG) through either an esophageal tube or nipple bottle at 2 h after birth followed by feeding pooled whole milk every 12 h after birth. Acetaminophen was mixed into the colostrum meal as a marker for abomasal emptying. A jugular catheter was inserted 1 h after birth and blood was sampled frequently to analyze serum for IgG and acetaminophen and plasma for glucose, insulin, GLP-1, and GLP-2. Feeding method did not affect abomasal emptying, and as a result no treatment effect was present on serum IgG concentrations. Maximum concentration of serum IgG was 24.4 +/- 0.40 mg/mL (+/- standard error), which was reached at 14.6 +/- 1.88 h after the colostrum meal for both groups. Apparent efficiency of absorption at maximum concentration of IgG was 52.9%, indicating high efficiency of passive transfer of IgG for both treatments. Tube feeding increased glucose and insulin area under the curve before the first milk meal, most likely due to the decreased time to consume the colostrum meal. In addition, tube-fed calves consumed 0.5 +/- 0.13 L more milk in their first milk meal than bottle-fed calves. No treatment effect on plasma concentrations of GLP-1 or GLP-2 was present, but both hormones increased after colostrum feeding. These findings confirm that there is no effect on absorption of IgG from colostrum when feeding good-quality colostrum at a volume of 3 L through either an esophageal tube or nipple bottle. PMID- 29454697 TI - Symposium review: Building a better cow-The Australian experience and future perspectives. AB - Genomic selection has led to opportunities for developing new breeding values that rely on phenotypes in dedicated reference populations of genotyped cows. In Australia, it has been applied to 2 novel traits: feed efficiency, which was released in 2015 as feed saved breeding values, and heat tolerance genomic breeding values, released for the first time in 2017. Feed saved is already included in the national breeding objective, which is focused on profitability and designed to be in line with farmer preferences. Our future focus is on traits associated with animal health, either directly or in combination with predictor traits, such as mid-infrared spectral data and, into the future, automated data capture. Although it is common for many evaluated traits to have genomic reliabilities ranging between 60 and 75%, many new, genomic information-only traits are likely to have reliabilities of less than 50%. Pooling of phenotype data internationally and investing in maintenance of reference populations is one option to increase the reliability of these traits; the other is to apply improved genomic prediction methods. For example, advances in the use of sequence data, in addition to gene expression studies, can lead to improved persistence of genomic breeding values across breeds and generations and potentially lead to greater reliabilities. Lower genomic reliabilities of novel traits could reduce the overall index reliability. However, provided these traits contribute to the overall breeding objective (e.g., profit), they are worth including. Bull selection tools and personalized genetic trends are already available, but increased access to economic and automatic capture farm data may see even better use of data to improve farm management and selection decisions. PMID- 29454698 TI - Udder health of dairy cows fed different dietary energy levels after a short or no dry period without use of dry cow antibiotics. AB - Reports on the effects of length of dry period (DP) on udder health of cows that were not treated with dry cow antibiotics are scarce. Additionally, the effects of a reduced dietary energy level for cows with a 0-d DP on udder health have not yet been studied. The aims of this study were (1) to compare effects of a 0-d or 30-d DP without use of dry cow antibiotics on udder health across the DP and subsequent lactation in dairy cows fed different dietary energy levels and (2) to evaluate associations between udder health and metabolic status of dairy cows. Five weeks before the expected calving date, Holstein-Friesian dairy cows (n = 115) were blocked for parity, expected calving date, and milk yield and somatic cell count (SCC) at their 2 last test days and were randomly assigned to 2 DP lengths: 0-d DP (n = 77) or 30-d DP (n = 38). Quarter milk samples were taken in wk 5 prepartum and in wk 1 and 5 postpartum. Proportion of quarters with elevated SCC (SCC >=200,000 cells/mL) and proportion of udder pathogens in quarter milk samples did not differ between DP lengths among weeks. After calving, 102 of these cows were randomly assigned to 3 treatments: a 30-d DP with a standard energy level required for expected milk yield (30-d DP SEL; n = 36), a 0-d DP with the same energy level as cows with a 30-d DP (0-d DP SEL; n = 33), and a 0-d DP with a low energy level (0-d DP LEL, n = 33). From wk 8 of lactation onward, cows received either a glucogenic ration consisting of corn silage and grass silage or a lipogenic ration consisting of grass silage and sugar beet pulp at a standard or low energy level. During wk 1 to 7 postpartum, treatment did not affect SCC or SCC corrected for milk yield. During wk 8 to 44 of lactation, 0-d DP SEL cows had a greater SCC than 0-d DP LEL or 30-d DP SEL cows and had a greater SCC corrected for milk yield than 0-d DP LEL cows. During wk 1 to 44 of lactation, occurrence of at least 1 elevation of SCC (SCC >=200,000 cells/mL after 2 wk of SCC <200,000 cells/mL) was not different among treatments. The 0-d DP SEL cows but not the 0-d DP LEL cows tended to have a 2.17 times greater hazard of having a case of clinical mastitis at any time in lactation than 30-d DP SEL cows. In wk 1 to 44 of lactation, lower fat- and protein- corrected milk yield and energy intake, greater energy balance, and greater plasma insulin concentration were associated with greater SCC. In conclusion, DP length did not affect udder health in the DP and in early lactation but seemed to decrease udder health for 0-d DP SEL cows in later lactation compared with 30-d DP SEL or 0-d DP LEL cows. PMID- 29454699 TI - Interrelations between the rumen microbiota and production, behavioral, rumen fermentation, metabolic, and immunological attributes of dairy cows. AB - Different studies have shown a strong correlation between the rumen microbiome and a range of production traits (e.g., feed efficiency, milk yield and components) in dairy cows. Underlying dynamics concerning cause and effect are, however, still widely unknown and warrant further investigation. The aim of the current study was to describe possible functional interrelations and pathways using a large set of variables describing the production, the metabolic and immunological state, as well as the rumen microbiome and fermentation characteristics of dairy cows in early lactation (n = 36, 56 +/- 3 d in milk). It was further hypothesized that the feed intake-associated behavior may influence the ruminal fermentation pattern, and a set of variables describing these individual animal attributes was included. Principal component analysis as well as Spearman's rank correlations were conducted including a total of 265 variables. The attained plots describe several well-known associations between metabolic, immunological, and production traits. Main drivers of variance within the data set included milk production and efficiency as well as rumen fermentation and microbiome diversity attributes, whereas behavioral, metabolic, and immunological variables did not exhibit any strong interrelations with the other variables. The previously well-documented strong correlation of production traits with distinct prokaryote groups was confirmed. This mainly included a negative correlation of operational taxonomic units ascribed to the Prevotella genus with milk and fat yield and feed efficiency. A central role of the animals' feed intake behavior in this context could not be affirmed. Furthermore, different methodological and interpretability aspects concerning the microbiome analysis by 16S rRNA gene sequencing, such as the discrepancy between taxonomic classification and functional communality, as well as the comparability with other studies, are discussed. We concluded that, to further investigate the driving force that causes the difference between efficient and inefficient animals, studies including more sophisticated methods to describe phenotypical traits of the host (e.g., rumen physiology, metabolic and genetic aspects) as well as the rumen microbiome (e.g., metagenome, metatranscriptome, metaproteome, and metabolome analysis) are needed. PMID- 29454700 TI - Technical note: An in vivo method to determine kinetics of unsaturated fatty acid biohydrogenation in the rumen. AB - Rumen microbial biohydrogenation (BH) of unsaturated fatty acids (UFA) has been extensively studied in vitro; however, in vitro BH pathways, rates, and extents may not parallel those in vivo. The objective was to develop an assay to assess in vivo rates, pathways, and extent of BH of oleic (OA), linoleic (LA), and alpha linolenic (ALA) acids. Each UFA was characterized in a separate experiment, each using 4 ruminally cannulated lactating Holstein cows. A single bolus consisting of 200 g of a UFA-oil [experiment 1 (EXP1): 87% OA sunflower, experiment 2 (EXP2): 70% LA safflower, and experiment 3 (EXP3): 54% ALA flaxseed] and 12 g of heptadecanoic acid (C17:0) was mixed into the rumen through the fistula. Rumen digesta was collected at -1, -0.25, 0.1, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4, and 6 h relative to the bolus. Overall, the triglyceride boluses increased total fatty acids (FA) in the rumen from 3.9 (standard deviation = +/-1.4) to 7.3% (+/-1.4) of rumen dry matter and enriched C17:0 from 0.4 (+/-0.1) to 2.5% (+/-0.5) of FA. The bolus enriched OA from 8.9 (+/-1.0) to 30.1% (+/-4.6) of FA in EXP1, LA from 11.1 (+/-1.8) to 35.9% (+/-5.0) of FA in EXP2, and ALA from 2.1 (+/-0.1) to 19.8% (+/-4.3) of FA in EXP3. The disappearances of C17:0, OA, LA, and ALA were fit to a single exponential decay model. The first-order rate of C17:0 rumen disappearance (turnover) was 9.1, 6.9, and 5.2%/h in EXP1, EXP2, and EXP3, respectively, and was used as a marker of FA passage. The rate of total rumen turnover of OA was 54.1%/h, LA was 60.5%/h, and ALA was 93.0%/h in EXP1, EXP2, and EXP3, respectively. Rumen concentration of all 3 UFA reached prebolus concentrations within 4 h. The calculated extent of lipolysis and initial isomerization was 85.6% for OA, 89.8% for LA, and 94.7% for ALA in EXP1, EXP2, and EXP3, respectively. Assuming that BH equals total disappearance minus passage, the rates of lipolysis and initial isomerization were 45.0, 53.6, and 87.8%/h for OA, LA, and ALA in EXP1, EXP2, and EXP3, respectively. Analysis of the data using compartmental modeling showed that the normal BH pathways proposed in the literature explained 46.0, 37.3, and 49.8% of the BH of OA, LA, and ALA in EXP1, EXP2, and EXP3, respectively. Based on the model, BH of trans C18:1 FA was the rate-limiting step to complete BH. Importantly, oils were provided as triglycerides and the reported rates represent the rate of lipolysis and BH. In conclusion, the rate of ruminal BH of OA, LA, and ALA was higher than that commonly observed in vitro, but the extent of BH was near expected values. The method developed provides a potential in vivo assay of ruminal BH for use in future experiments and modeling efforts. PMID- 29454701 TI - Fatty acid elongase 5 (ELOVL5) alters the synthesis of long-chain unsaturated fatty acids in goat mammary epithelial cells. AB - Increased production of long-chain unsaturated fatty acids (LCUFA) can have a positive effect on the nutritional value of ruminant milk for human consumption. In nonruminant species, fatty acid elongase 5 (ELOVL5) is a key enzyme for endogenous synthesis of long-chain unsaturated fatty acids. However, whether ELOVL5 protein plays a role (if any) in ruminant mammary tissue remains unclear. In the present study, we assessed the mRNA abundance of ELOVL5 at 3 stages of lactation in goat mammary tissue. Results revealed that ELOVL5 had the lowest expression at peak lactation compared with the nonlactating and late-lactating periods. The ELOVL5 was overexpressed or knocked down to assess its role in goat mammary epithelial cells. Results revealed that ELOVL5 overexpression increased the expression of perilipin2 (PLIN2) and decreased diacylglycerolacyltransferase 2 (DGAT2) and fatty acid desaturase 2 (FADS2) mRNA, but had no effect on the expression of DGAT1, FADS1, and stearoyl-CoA desaturase 1 (SCD1). Overexpression of ELOVL5 decreased the concentration of C16:1n-7, whereas no significant change in C18:1n-7 and C18:1n-9 was observed. Knockdown of ELOVL5 decreased the expression of PLIN2 but had no effect on DGAT1, DGAT2, FADS1, FADS2, and SCD1 mRNA expression. Knockdown of ELOVL5 increased the concentration of C16:1n-7 and decreased that of C18:1n-7. The alterations of expression of genes related to lipid metabolism after overexpression or knockdown of ELOVL5 suggested a negative feedback regulation by the products of ELOVL5 activation. However, the content of triacylglycerol was not altered by knockdown or overexpression of ELOVL5 in goat mammary epithelial cells, which might have been due to the insufficient availability of substrate in vitro. Collectively, these are the first in vitro results highlighting an important role of ELOVL5 in the elongation of 16-carbon to 18-carbon unsaturated fatty acids in ruminant mammary cells. PMID- 29454702 TI - C-C motif chemokine ligand 2 induces proliferation and prevents lipopolysaccharide-induced inflammatory responses in bovine mammary epithelial cells. AB - C-C motif chemokine ligand 2 (CCL2) is a small chemokine which belongs to the CC type chemokine family, and has chemoattractant activity for recruitment of monocytes to sites of inflammation. Overexpressed CCL2 binding to its receptor C C chemokine receptor 2 increases the risk of breast cancer in humans, but its effects on proliferation of bovine mammary epithelial cells is not known. Maintaining a high level of proliferative activity in bovine mammary epithelial cells during lactation is important for improving milk yield and can benefit the dairy industry economically. In the present study, we demonstrated that CCL2 induces proliferation of MAC-T cells, a bovine mammary epithelial cell line, and stimulates progression of the cell cycle through stimulation of expression of cyclin D1. Moreover, CCL2 activates phosphoinositide 3-kinase (PI3K)/AKT [AKT, P70-S6 kinase 1 (P70S6K), ribosomal protein S6 (S6)] and mitogen activated protein kinase (MAPK) [extracellular signal-regulated kinase-1/2 (ERK1/2), c-Jun N-terminal kinase (JNK), and P38] pathways, which are involved in proliferation of MAC-T cells, as evidenced by co-treatment of MAC-T cells with pharmacological inhibitors of cell signaling transcription factors including Wortmannin, U0126, and SP600125. The CCL2 in MAC-T cells attenuates endoplasmic reticulum stress induced by tunicamycin, suggesting that CCL2 regulates intracellular synthesis of proteins and lipids and prevents activation of apoptotic pathways initiated in response to endoplasmic reticulum stress. Furthermore, CCL2 is involved in alleviating lipopolysaccharide (LPS)-induced inflammatory responses in MAC-T cells by reducing LPS-induced expression of IL8, IL6, and nuclear factor kappa B subunit 1 (NFKB1). Collectively, CCL2 is a novel target for improving the quantity and quality of milk from cows through stimulation of proliferation on mammary epithelial cells and attenuation of LPS-induced inflammatory responses. PMID- 29454703 TI - Synthesis and evaluation of novel dolastatin 10 derivatives for versatile conjugations. AB - Dolastatin 10 (1) is a highly potent cytotoxic microtubule inhibitor (cytotoxicity IC50 < 5.0 nM) and several of its analogs have recently been used as payloads in antibody drug conjugates. Herein, we describe the design and synthesis of a series of novel dolastatin 10 analogs useful as payloads for conjugated drugs. We explored analogs containing functional groups at the thiazole moiety at the C-terminal of dolastatin 10. The functional groups included amines, alcohols, and thiols, which are representative structures used in known conjugated drugs. These novel analogs showed excellent potency in a tumor cell proliferation assay, and thus this series of dolastatin 10 analogs is suitable as versatile payloads in conjugated drugs. Insights into the structure activity relationships of the analogs are also discussed. PMID- 29454704 TI - Selective inhibition of CYP2C8 by fisetin and its methylated metabolite, geraldol, in human liver microsomes. AB - Fisetin is a flavonol compound commonly found in edible vegetables and fruits. It has anti-tumor, antioxidant, and anti-inflammatory effects. Geraldol, the O methyl metabolite of fisetin in mice, is reported to suppress endothelial cell migration and proliferation. Although the in vivo and in vitro effects of fisetin and its metabolites are frequently reported, studies on herb-drug interactions have not yet been performed. This study was designed to investigate the inhibitory effect of fisetin and geraldol on eight isoforms of human cytochrome P450 (CYP) by using cocktail assay and LC-MS/MS analysis. The selective inhibition of CYP2C8-catalyzed paclitaxel hydroxylation by fisetin and geraldol were confirmed in pooled human liver microsomes (HLMs). In addition, an IC50 shift assay under different pre-incubation conditions confirmed that fisetin and geraldol shows a reversible concentration-dependent, but not mechanism-based, inhibition of CYP2C8. Moreover, Michaelis-Menten, Lineweaver-burk plots, Dixon and Eadie-Hofstee showed a non-competitive inhibition mode with an equilibrium dissociation constant of 4.1 MUM for fisetin and 11.5 MUM for geraldol, determined from secondary plot of the Lineweaver-Burk plot. In conclusion, our results indicate that fisetin showed selective reversible and non-competitive inhibition of CYP2C8 more than its main metabolite, geraldol, in HLMs. PMID- 29454705 TI - Schwann cell precursor: a neural crest cell in disguise? AB - Schwann cell precursors (SCPs) are multipotent embryonic progenitors covering all developing peripheral nerves. These nerves grow and navigate with unprecedented precision, delivering SCP progenitors to almost all locations in the embryonic body. Within specific developing tissues, SCPs detach from nerves and generate neuroendocrine cells, autonomic neurons, mature Schwann cells, melanocytes and other cell types. These properties of SCPs evoke resemblances between them and their parental population, namely, neural crest cells. Neural crest cells are incredibly multipotent migratory cells that revolutionized the course of evolution in the lineage of early chordate animals. Given this similarity and recent data, it is possible to hypothesize that proto-neural crest cells are similar to SCPs spreading along the nerves. Here, we review the multipotency of SCPs, the signals that govern them, their potential therapeutic value, SCP's embryonic origin and their evolutionary connections. We dedicate this article to the memory of Wilhelm His, the father of the microtome and "Zwischenstrang", currently known as the neural crest.

AB - Recently, Zika virus (ZIKV) emerged as a global public health concern and is distinct from other flaviviruses in many aspects, for example, causing transplacental infection, fetal abnormalities and vector-independent transmission through body fluids in humans. The capsid (C) protein is a multifunctional protein, since it binds to viral RNA in the process of nucleocapsid assembly and plays important roles in virus infection processes by interacting with cellular proteins, modulating cellular metabolism, apoptosis and immune response. Here we solved the crystal structure of ZIKV C protein at a resolution of 1.9A. The ZIKV C protein structure contains four alpha helices with a long pre-alpha1 loop and forms dimers. The unique long pre-alpha1 loop in ZIKV C contributes to the tighter association of dimeric assembly and renders a divergent hydrophobic feature at the lipid bilayer interface in comparison with the known C structures of West Nile and dengue viruses. We reported the interaction between the ZIKV C protein and lipid droplets through confocal microscopy analysis. Substitutions of key amino acids in the pre-alpha1 loop of ZIKV C disrupted the interaction with lipid droplets, indicating that the loop is critical for membrane association. We also recognized that ZIKV C protein possesses broad binding capability to different nucleotide types, including single-stranded and double-stranded RNAs or DNAs. Furthermore, the highly positively charged interface, mainly formed by alpha4 helix, is proposed to be responsible for nucleotide binding. These findings will greatly enhance our understanding of ZIKV C protein, providing information for anti-ZIKV drug design targeting the C protein.

AB - The transcription factor GATA6 and the Fgf/Ras/MAPK signaling pathway are essential for the development of the primitive endoderm (PrE), one of the two lineages derived from the pluripotent inner cell mass (ICM) of mammalian blastocysts. A mutant mouse line in which Gata6-coding exons are replaced with H2BGFP (histone H2B Green Fluorescence Protein fusion protein) was developed to monitor Gata6 promoter activity. In the Gata6-H2BGFP heterozygous blastocysts, the ICM cells that initially had uniform GFP fluorescence signal at E3.5 diverged into two populations by the 64-cell stage, either as the GFP-high PrE or the GFP low epiblasts (Epi). However in the GATA6-null blastocysts, the originally moderate GFP expression subsided in all ICM cells, indicating that the GATA6 protein is required to maintain its own promoter activity during PrE linage commitment. In embryonic stem cells, expressed GATA6 was shown to bind and activate the Gata6 promoter in PrE differentiation. Mutations of a conserved serine residue (S264) for Erk1/2 phosphorylation in GATA6 protein drastically impacted its ability to activate its own promoter. We conclude that phosphorylation of GATA6 by Erk1/2 compels exit from pluripotent state, and the phosphorylation propels a GATA6 positive feedback regulatory circuit to compel PrE differentiation. Our findings resolve the longstanding question on the dual requirements of GATA6 and Ras/MAPK pathway for PrE commitment of the pluripotent ICM. PMID- 29454708 TI - Incidence and Risk of Oxaliplatin-Induced Hypersensitivity in Patients with Asymptomatic Prior Exposure: A Prospective Observational Study. AB - BACKGROUND: Oxaliplatin-related hypersensitivity reactions (HSRs), which can be life threatening, have introduced a dilemma regarding the use of chemotherapeutic agents. Because repeated exposure to oxaliplatin may increase the risk of sensitization, patients with a history of prior asymptomatic exposure require risk-stratified care. OBJECTIVE: This study aimed to elucidate the incidence and risk of oxaliplatin HSRs in patients with a history of asymptomatic prior exposure. METHODS: We performed a prospective observational study of patients who completed oxaliplatin-based chemotherapy between March 2013 and January 2015. Prior exposure to oxaliplatin, the oxaliplatin-free interval, reaction severity, eosinophil counts, and premedication were reviewed to assess the risk factors. RESULTS: A total of 793 patients were enrolled, among whom 148 (18.7%) experienced an HSR. The HSR incidence was 15.2% among oxaliplatin-naive patients but increased to 31.9% among those with a history of asymptomatic exposure and 75.0% among those with a history of oxaliplatin HSRs during the previous exposure, despite prophylaxis. The mean HSR onset cycle was earliest in the previous HSR group, followed by the previous asymptomatic exposure and nonexposure groups. The HSR severity also differed according to the previous exposure history and HSRs. In the multivariate analysis, prior exposure to oxaliplatin (odds ratio [OR], 3.78; 95% confidence interval [CI], 2.46-5.79) and a longer oxaliplatin-free interval (>=36 months; OR, 4.85; 95% CI, 1.60-14.37) were independent risk factors for HSRs. CONCLUSIONS: Previous exposure to oxaliplatin is a risk factor for earlier HSR onset and more severe and frequent HSR episodes, even if prior therapy was well tolerated. PMID- 29454709 TI - In Vitro Diagnosis of Immediate Drug Hypersensitivity During Anesthesia: A Review of the Literature. AB - Quantification of specific IgE (sIgE) antibodies constitutes an important measure to document anesthesia-related immediate hypersensitivity reactions (IHRs). However, only a few drug-specific assays are available and their predictive value is not known. In cases of non-IgE mediated IHRs, diagnosis might benefit from cellular tests such as basophil mediator release tests and basophil activation tests (BATs). To review the potential and limitations of quantification of sIgE, mediator release, and BAT in anesthesia-related IHRs, a literature search was conducted using the key words allergy, basophil activation, CD63, CD203c, diagnosis, drugs, hypersensitivity, flow cytometry, MRGPRX2, specific IgE antibodies, leukotrienes, histamine, and tryptase; this was complemented by the authors' experience. The drugs and compounds that have predominantly been studied are neuromuscular blocking agents (NMBAs), beta-lactams, latex, and chlorhexidine. For sIgE NMBA, sensitivity and specificity varies between 38.5% to 92% and 92% to 100%, respectively. For sIgE beta-lactams, sensitivity varies between 0% to 85% and specificity between 52% to 100%. sIgE to morphine should not be used in isolation to diagnose IHRs to NMBAs or opiates. sIgE for latex, and, in difficult cases, molecular diagnosis with quantification of sIgE to Hevea components constitute reliable diagnostics. For drugs, the sensitivity of BAT varies between 50% and 60% and specificity reaches 80% to 90%. Basophil mediator release tests seem to be abandoned and supplanted by BATs. PMID- 29454710 TI - Experiences of guilt, shame and blame in those affected by burns: A qualitative systematic review. AB - BACKGROUND: A significant burn can severely impact the lives of survivors and their carers. This systematic review sought to incorporate the experiences of guilt, blame and shame across the lifespan for burn survivors, their families as well as the experiences of the parents of burned children. METHODS: A systematic review of qualitative studies on the experiences and perspectives of guilt, blame and shame by those affected by burn trauma across the lifespan. The databases, Pubmed, Scopus, EMBASE, CINAHL, PsychINFO were systematically searched. Authors independently rated the reporting of the qualitative studies included. Thematic synthesis was used to analyse the data. The search identified 230 papers. Eighteen research papers met the study inclusion criteria. RESULTS: Guilt and ruminations of guilt, blame attribution and shame and body image were identified during thematic analysis as pivotal factors across the lifespan for burn survivors, their families as well as the experiences of the parents of burn injured children. Accounts presented, suggest that the impact of burns on the lives of the survivor and family covers a diverse spectrum of impact; personal, cultural and societal. CONCLUSION: From the findings of the literature searches and the post-burn experiences described in this review there is a gap in the psychological care for burn survivors and their caregivers. This is specifically relevant around issues of parental guilt and blame, ruminations of guilt and shame as well as body image. These findings may not be new to burns professionals but the key message is that management of these issues fall short of delivering comprehensive post trauma care. Identifying and highlighting the importance of residual psychosocial problems will ultimately influence positive outcomes for burn survivors. PMID- 29454711 TI - Outcomes of post burn flexion contracture release under tourniquet versus tumescent technique in children. AB - OBJECTIVE: To compare the clinical outcomes of release of flexion contractures after burn of the hand in children using tourniquet or tumescent technique in terms of operative time, postoperative pain score, and percentage of graft take. METHODS: Patients aged 3 to 12 years who required release of post-burn flexion contractures involving volar aspect of palm and fingers were enrolled from outpatient clinic. Patients were randomized in 1:1 ratio to the use of either tumescent technique or tourniquet during contracture release. Duration of procedure, postoperative pain score, percentage of graft take, and any complications were assessed and analyzed in both groups by a blinded observer. RESULTS: Of the 160 patients randomized in the study (80 in each group), 84 (52.5%) were males. The mean+/-SD age of participants was 7.84+/-3.49 years, with no statistically significant difference in gender and age distribution between the groups. Similarly, there was no statistically significant difference in duration of surgery in both groups. However, there was a statistically significant difference in percentage of graft take at the 14th postoperative day; significantly more graft take was noted in the tumescent group (8.97+/-3.7cm vs. 7.26+/-2.6cm; P=0.001). Mean analgesia consumed in the tumescent group was significantly less than that of the tourniquet group (6.26+/-1.9mg vs. 9.41+/ 2.2mg; P<=0.001). Similarly, statistically significant difference in the mean FLACC pain score was noted, with remarkably low pain score in the tumescent group. CONCLUSION: We found that the use of the tumescent technique for the release of flexion contracture resulted in better graft take, lower pain scores, and lesser consumption of analgesic than the use of tourniquet.

AB - BACKGROUND: Emergency physicians differ in many ways with respect to practice. One area in which interphysician practice differences are not well characterized is emergency department (ED) length of stay (LOS). OBJECTIVE: To describe how ED LOS differs among physicians. METHODS: We performed a 3-year, five-ED retrospective study of non-fast-track visits evaluated primarily by physicians. We report each provider's observed LOS, as well as each provider's ratio of observed LOS/expected LOS (LOSO/E); we determined expected LOS based on site average adjusted for the patient characteristics of age, gender, acuity, and disposition status, as well as the time characteristics of shift, day of week, season, and calendar year. RESULTS: Three hundred twenty-seven thousand, seven hundred fifty-three visits seen by 92 physicians were eligible for analysis. For the five sites, the average shortest observed LOS was 151 min (range 106-184 min), and the average longest observed LOS was 232 min (range 196-270 min); the average difference was 81 min (range 69-90 min). For LOSO/E, the average lowest LOSO/E was 0.801 (range 0.702-0.887), and the average highest LOSO/E was 1.210 (range 1.186-1.275); the average difference between the lowest LOSO/E and the highest LOSO/E was 0.409 (range 0.305-0.493). CONCLUSION: There are significant differences in ED LOS at the level of the individual physician, even after accounting for multiple confounders. We found that the LOSO/E for physicians with the lowest LOSO/E at each site averaged approximately 20% less than predicted, and that the LOSO/E for physicians with the highest LOSO/E at each site averaged approximately 20% more than predicted. PMID- 29454715 TI - [Sleepiness, continuous positive airway pressure and the obstructive sleep apnea hypopnea syndrome]. AB - Excessive daytime sleepiness is a major symptom in cases of the obstructive sleep apnea-hypopnea syndrome. Most often, it is vastly improved by treatment with continuous positive airway pressure (CPAP). The most effective way to confirm its disappearance is through wakefulness maintenance testing. If residual sleepiness remains, despite CPAP, further diagnostic investigation must be carried out. Firstly, it must be assessed whether the treatment is fully effective (apnea hypopnea index<10/h) by examining flow limitations under treatment (polysomnography) and whether it is sufficiently used (>6h/night). If this is the case, the possibility of other situations responsible for excessive daytime sleepiness must be reviewed and eliminated, whether they are depression, sleep insufficiency, use of intoxicants, obesity, restless legs syndrome, or circadian sleep-wake cycle disorder. If not, the multiple sleep latency tests make it possible to assess sleepiness (latency<8min) and can lead to a diagnosis of central hypersomnia (narcolepsy, idiopathic hypersomnia, hypersomnia due to a medical pathology). In some rare cases (about 6% of patients) investigations will reveal central hypersomnia due to the obstructive sleep apnea-hypopnea syndrome or "lesional" hypersomnia due to intermittent hypoxia. Since 2011, medications treating excessive sleepiness have had marketing authorization only for narcolepsy in France. However, they can be administered by way of derogation to other neurological hypersomnias on prescription by a reference centre or a centre with expertise in hypersomnia. PMID- 29454716 TI - Emergency Management of Priapism in the United Kingdom: A Survey of Current Practice. AB - BACKGROUND: Despite its importance, current practice in the emergency management of priapism in the United Kingdom is unknown. AIM: To evaluate current practice in the emergency management of priapism in the United Kingdom. METHODS: All "full," "associate urological specialist," and "trainee" members of the British Association of Urological Surgeons (BAUS; leading membership-based organization for practitioners of urologic surgery in the United Kingdom) were invited to participate in an online survey. Questions related to the emergency management of priapism, access to tertiary andrology services, and use of guidelines. OUTCOMES: Key outcome measures included frequency of encountered cases, access to specialist andrology support, confidence in key management steps, and use of current guidelines. RESULTS: 213 of 1,304 (16.3%) eligible members completed the survey. Most reported managing 1 case annually (median = 1, range = 0->10). Only 7.0% transferred patients to a tertiary center and 87.8% believed they could access specialist andrology advice if required. Respondents were less confident in performing intracavernosal phenylephrine instillation (88.7%) compared with corporal aspiration (98.1%), with confidence lowest among trainee members. Only 68.5% reported performing the distal shunt procedure. Of the 212 respondents that chose to answer questions relating to guidelines, only 155 (73.1%) were aware of their existence, with those published by the European Association of Urology being most popular (53.8%). 205 (96.2%) respondents expressed an interest in the development of a UK-specific guideline, with 162 of 212 (76.4%) stating they would use this in practice. CLINICAL IMPLICATIONS: Urologists in the United Kingdom support the development of UK-specific guidance on the emergency management of priapism for use within the context of the National Health Service. STRENGTHS AND LIMITATIONS: This is the first study to assess current practice in the emergency management of priapism in the United Kingdom. Its strength is that most UK urologists were invited to participate through collaboration with the BAUS. Although the response rate of 16.3% is acceptable for a national survey of this nature, responses were self-reported, rendering them susceptible to bias. CONCLUSION: This study demonstrates that some UK urologists lack confidence in key steps in the emergency management of priapism and identifies a strong level of support for the development of up-to-date UK-specific guidance.

PMID- 29454717 TI - Superior Approach for Supracardiac Total Anomalous Pulmonary Venous Connection. AB - BACKGROUND: Studies on the outcomes of surgical repair for supracardiac total anomalous pulmonary venous connection through the superior approach are uncommon. METHODS: From January 2004 to January 2016, 198 patients with supracardiac total anomalous pulmonary venous connection underwent side-to-side anastomosis between the common pulmonary vein and left atrium through the superior approach. Kaplan Meier curve was used to demonstrate the survival estimates. Cox proportional hazard model and competing risk regression model were used to identify risk factors for death and postoperative pulmonary venous obstruction. RESULTS: There were six in-hospital deaths and no late deaths. The survival rates at 30 days, 1 year, and 12 years were 97%, 97%, and 97%, respectively. Follow-up was completed in 92.2% of the survivors. Median follow-up was 47 months (range: 0 to 136 months). Twenty-seven patients (14.1%, 27 of 192) required reoperation for pulmonary venous obstruction, residual atrial septal defect, or superior cava vena syndrome. Multivariable analysis showed that preoperative pulmonary venous obstruction (p = 0.012), longer duration of ventilation (p = 0.011), and emergency operation (p = 0.010) were incremental risk factors for death. Aortic cross-clamp time (p < 0.001) and preoperative pulmonary venous obstruction (p = 0.002) were associated with postoperative pulmonary venous obstruction. CONCLUSIONS: Side-to-side anastomosis through a superior approach in surgical repair of supracardiac total anomalous pulmonary venous connection can achieve satisfactory results. PMID- 29454718 TI - Learning Curve for Robot-Assisted Minimally Invasive Thoracoscopic Esophagectomy: Results From 312 Cases. AB - BACKGROUND: Thoracic laparoscopic robot-assisted minimally invasive esophagectomy (RAMIE) was developed in 2003. RAMIE was shown to be safe and oncologically effective. The aim of this study was to assess the learning curve and the proctoring program for a newly introduced surgeon (surgeon 2). METHODS: The "learning curve" was defined as the number of operations that must be performed by a surgeon to achieve a steady level of performance. Measures of proficiency to describe the learning curve of the proctor and the newly introduced surgeon 2 included operating time, blood loss, and conversion rates and were analyzed using the cumulative sum method. Results of the newly introduced surgeon were compared with the proctor in the same period of time. RESULTS: The proctor performed 232 of 312 procedures (74%) and surgeon 2 performed 80 of 312 procedures (26%). The proctor reached proficiency after 70 procedures in 55 months. The structured proctoring program for surgeon 2 started with 20 procedures as assisting table surgeon, followed by 5 observational and 15 supervised cases. Surgeon 2 performed at the same level as the proctor concerning operating time, blood loss, conversion rates, radicality, and complications. For surgeon 2, the learning phase of thoracic laparoscopic RAMIE was completed within 24 cases (15 supervised and 9 independent cases) in 13 months; a reduction of 66% in the number of operations and a reduction of 76% in time, compared with the proctor. CONCLUSIONS: The learning phase of thoracic laparoscopic RAMIE consisted of 70 procedures in 55 months. A structured proctoring for RAMIE substantially reduced the number of procedures and time required to achieve proficiency. PMID- 29454719 TI - Supply Shortages: A Silver Lining.

AB - OBJECTIVES: This study sought to assess the prevalence and clinical impact of silent diabetes and pre-diabetes in "nondiabetic" percutaneous coronary intervention (PCI) all-comers. BACKGROUND: Patients with undetected and thus untreated (silent) diabetes may have higher event risks after PCI with contemporary drug-eluting stents (DES). METHODS: The BIO-RESORT Silent Diabetes study, performed at Thoraxcentrum Twente, is a substudy of the randomized multicenter BIO-RESORT (BIOdegradable Polymer and DuRable Polymer Drug-eluting Stents in an All COmeRs PopulaTion) trial (NCT01674803). Patients underwent oral glucose tolerance testing (OGTT), and assessment of glycosylated hemoglobin with fasting plasma glucose. Primary endpoint was a composite of cardiac death, target vessel-related myocardial infarction, or target vessel revascularization at 1 year. RESULTS: Of the 988 participants, OGTT detected silent diabetes in 68 (6.9%), pre-diabetes in 133 (13.3%), and normal glucose metabolism in 788 (79.8%). Patients with silent diabetes had higher primary endpoint rates (13.2% vs. 7.6% vs. 4.8%; p < 0.001; silent diabetes vs. normal: hazard ratio: 4.2; 95% confidence interval: 1.9 to 9.2). Differences were driven by myocardial infarction (p < 0.001) which occurred mostly <48 h. Based on glycosylated hemoglobin and fasting plasma glucose, silent diabetes was found in 33 (3.3%) patients, pre-diabetes in 217 (22.0%) patients, and normal glucose metabolism in 738 (74.7%) patients; primary endpoint rates were similar to OGTT-based analyses (12.1% vs. 5.5% vs. 3.1%; p = 0.01). Multivariate analyses demonstrated that abnormal glucose metabolism by either diagnostic approach, present in 330 (33.4%) patients, independently predicted adverse event risk (hazard ratio: 2.2; 95% confidence interval: 1.2 to 4.2). CONCLUSIONS: Abnormal glucose metabolism was detected in 1 of 3 "nondiabetic" PCI patients and was independently associated with up to 4-fold higher event risks. Future intervention trials should determine whether meaningful benefits accrue from routine glycemia testing in such patients.

AB - OBJECTIVES: This study sought to evaluate the optimal duration of dual antiplatelet therapy (DAPT) after the implantation of a drug-eluting stent (DES) in elderly patients. BACKGROUND: Qualified studies to evaluate the optimal duration of DAPT in elderly patients have been very limited. METHODS: Using 6 randomized trials that compared short-term (<=6 months) and long-term (12 months) DAPT, individual participant data meta-analysis was performed in elderly patients (>=65 years of age). The primary study outcome was the 12-month risk of a composite of myocardial infarction, definite or probable stent thrombosis, or stroke. The major secondary outcome was the 12-month risk of major bleeding. RESULTS: The primary outcome risk did not significantly differ between patients receiving short-term and long-term DAPT (hazard ratio [HR]: 1.12; 95% confidence interval [CI]: 0.88 to 1.43; p = 0.3581) in the overall group of study participants. In subgroup analysis, a significant interaction between age and DAPT duration was observed for primary outcome risk (p for interaction = 0.0384). In the subset of younger patients (<65 years of age, n = 6,152), short-term DAPT was associated with higher risk of primary outcome (HR: 1.67; 95% CI: 1.14 to 2.44; p = 0.0082). In elderly patients (n = 5,319), however, the risk of primary outcome did not significantly differ between patients receiving short-term and long-term DAPT (HR: 0.84; 95% CI: 0.60 to 1.16; p = 0.2856). Short-term DAPT was associated with a significant reduction in major bleeding compared with long-term DAPT (HR: 0.50; 95% CI: 0.30 to 0.84; p = 0.0081) in the overall group, and particularly in elderly patients (HR: 0.46; 95% CI: 0.24-0.88; p = 0.0196). CONCLUSIONS: Short-term DAPT after new-generation DES implantation may be more beneficial in elderly patients than in younger patients. PMID- 29454731 TI - Significance of novel subcortical low intensity score on transient neurological events after revascularization surgery for moyamoya disease. AB - OBJECTIVES: Transient neurological events (TNEs) are frequently observed after revascularization surgery for moyamoya disease (MMD). Recently, two signs on fluid-attenuated inversion recovery magnetic resonance images, a cortical hyperintensity belt (CHB) sign possibly reflecting vasogenic edema and a transient subcortical low intensity (SCLI) sign possibly reflecting cytotoxic edema, were reported associated with TNEs. The purpose of this study was to create a SCLI score and to investigate the significance of the score in TNEs. PATIENTS AND METHODS: The authors retrospectively analyzed 18 cerebral hemispheres in 16 consecutive patients with revascularization surgery for MMD. The SCLI sign was defined as a transient SCLI in surgically treated hemispheres, and blindly graded as the SCLI score (0-4) based on the extent. The relationships among SCLI, CHB signs and TNEs were evaluated. RESULTS: Postoperative TNEs, SCLI and CHB signs were detected in 8 (44.4%), 9 (50.0%) and 12 (66.7%) hemispheres, respectively. Patients with SCLI and CHB signs had a significantly higher TNE occurrence rate than those without these signs (p = 0.015, and p = 0.013, respectively). Patients with TNEs showed significantly higher SCLI scores than those without TNEs (p = 0.009), while the difference of CHB scores did not reach significance between patients with and without TNEs. For the occurrence of postoperative TNEs, SCLI score with a cut-off value of 1.0 resulted in a specificity of 80.0% and a sensitivity of 87.5%. CONCLUSION: The novel SCLI score may be useful for diagnosing TNEs after revascularization surgery for MMD, although both vasogenic and cytotoxic edema may be involved in postoperative TNEs. PMID- 29454732 TI - Genetic interaction and diversity of the families Libellulidae and Gomphidae through COI gene from China and Pakistan. AB - A total of 300 dragonflies (Odonata) were collected from six different localities of China and Pakistan. Sixty seven representative samples were selected to sequence their mitochondrial cytochrome oxidase subunit I (COI). An examination of the resultant sequences identified 21 different dragonfly species, belonging to 15 distinct genera, two families, Libellulidae and Gomphidae. Sequence alignment was executed using Clustal-W in BioEdit v6. The phylogenetic tree was constructed through Neighbor-joining method by using Jukes-Cantor model, and genetic divergence was calculated via Kimura 2-parameter using MEGA7, while Genetic diversity was calculated by DnaSP v5. The maximum genetic divergence was observed for Crocothemis servilia, at 20.49%, followed by Libellulidae sp. with 22.30% while minimum divergence (0.82%) was observed for Melligomphus ardens. Likewise, a significant genetic diversity was observed for all species. However, Crocothemis servilia species presented maximum value (176 mutations) followed by Libellulidae spp. (150 mutations), whereas minimum value (3 mutations) was observed by Orthetrum testaceum. Interestingly, the diversity of C. servilia, all of which are collected from a single location of China, is much higher than those from Pakistan, which were collected from 5 different places with a spatial distance exceeding 500 Kms. Our results are useful in gaining a full appreciation of the global diversity of dragonflies and the development of conservation measures of this insect. PMID- 29454733 TI - Characterization of fungus microbial diversity in healthy and diarrheal yaks in Gannan region of Tibet Autonomous Prefecture. AB - Diarrhea is a serious epidemic in yaks on Qinghai Tibet plateau, but the exact pathogen is not confirmed. Diarrhea is related to the changes in diversity of intestinal flora. The current study herein is performed for high-throughput sequencing of fungus microbial diversity in healthy adult yaks, diarrheal adult yaks and diarrheal yak calves in Gannan Tibetan Autonomous Prefecture. A total 446726 optimized sequences were achieved. Over 250 OTUs in species level have been indentified for each sample. The Shannon and Simpson index revealed that there was no visible difference in the flora between different yak groups (p > 0.05). However, obvious difference was watched in the principal component of microbial community structure in different yak groups by PCA analysis, especially between healthy adult yak group and diarrheal adult yak groups. There were 248 fungus species shared in three groups. Interestingly, there were 97 fungus species shared in the diarrheal groups (calves and adult yaks), which were not found in the healthy yaks, while there were 212 fungus species only found in the healthy yaks. In the Phylum level, 1 phylum (Neocallimastigomycota) was discovered to have significant difference between healthy yaks and diarrheal yak calves (p < 0.05). In the genus level, 23 genus were found obvious difference between healthy adult yaks and diarrheal adults yaks (p < 0.05); 28 genus were found significant difference between healthy adult yaks and diarrheal yak calves (p < 0.05); 23 genus were found obvious difference between diarrheal adult yaks and diarrheal yak calves (p < 0.05). The present study herein first reported an insight of the change of microbial diversity of fungus in diarrhea yaks at altitude regions, which contributed towards the solid prevention of diarrhea in yaks. PMID- 29454734 TI - Management of arthropod vector data - Social and ecological dynamics facing the One Health perspective. AB - Emerging infectious diseases (EIDs) are spread by direct and/or indirect contacts between a pathogen or parasite and their hosts. Arthropod vectors have evolved as excellent bloodsuckers, providing an elegant transportation mode for a wide number of infectious agents. The nature of pathogen and parasite transfer and the models used to predict how a disease might spread are magnified in complexity when an arthropod vector is part of the disease cycle. One Health is a worldwide strategy for expanding interdisciplinary collaborations and communications in all aspects of health care for humans, animals and the environment. It would benefit from a structured analysis to address vectoring of arthropod-borne diseases as a dynamic transactional process. This review focused on how arthropod vector data can be used to better model and predict zoonotic disease outbreaks. With enhanced knowledge to describe arthropod vector disease transfer, researchers will have a better understanding about how to model disease outbreaks. As public health research evolves to include more social-ecological systems, the roles of society, ecology, epidemiology, pathogen/parasite evolution and animal behavior can be better captured in the research design. Overall, because of more collaborative data collection processes on arthropod vectors, disease modeling can better predict conditions where EIDs will occur.

AB - Strongyloidiasis is an important helminthiasis affecting million people worldwide. The aim of this study was to use sodium metaperiodate (MP) treatment to immunochemically characterize Strongyloides venezuelensis filariform larvae and use MP-treated heterologous antigen to detect IgG and subclasses in serum. Samples from individuals with definitive diagnosis of strongyloidiasis (n = 50), other parasitic diseases (n = 60) and negative endemic (n = 50) were tested. TG ROC and two-way ANOVA were applied. MP-treatment resulted on differential localization of carbohydrates at larval structure and no carbohydrate content in saline extract (SE). Electrophoretic profiles were similar before and after treatment. ELISA sensitivity and specificity were: 90%; 88.2% for SE and 92.0%; 94.6% for MP, respectively. When using MP treated antigen we observed reduction in IgG1 and IgG3 detection in strongyloidiasis group and decrease of cross reactions in control groups. Our data demonstrate the role of carbohydrate residues in cross reactions and on the recognition of anti-Strongyloides IgG and its subclasses.

AB - PURPOSE: The value of adjuvant radiotherapy for patients with positive lymph nodes after curative resection of oesophageal squamous cell carcinoma is controversial. This study aims to investigate its long-term benefits in a specific cohort. PATIENTS AND METHODS: The charts between 1990 and 2003 from patients with positive lymph nodes were retrospectively reviewed. Those subjects were divided into adjuvant radiotherapy and surgery alone groups, with two subgroups defined by radiation dose (cutoff value: 50Gy). Overall survival, disease-free survival and locoregional recurrence-free survival were compared between two groups, with predictive factors of overall survival analysed meanwhile. RESULTS: In sum, 175 matched patients with 1:2 ratios for group balance were enrolled for final analysis. During the follow-up (median: 37.0 months), 143 (81.7%) deaths were recorded, with 70.6% of deaths from cancer progression. The median overall survival time (19.5, 4 to 172 months) was not significantly different between the two groups (18.9 vs. 20.0 months, P=0.179). However, the disease-free survival time was significantly shorter in the adjuvant radiotherapy group than that in the control group (median, 11.5 vs. 14.9 months; P=0.001), with the locoregional recurrence-free survival time impressively prolonged (median: 18.3 vs. 16.5 months; P=0.022). Age (P=0.030), number (P=0.005) and ratio (P=0.002) of positive lymph nodes were associated with overall survival, but radiation dose was not (P=0.204). CONCLUSION: Adjuvant radiotherapy with low- or high-dose did not improve survival compared with surgery alone. However, radiotherapy was effective to control locoregional recurrence, and could be applied as salvage therapy when recurrence event occurred.

AB - INTRODUCTION: Donor milk is the second best alternative for a newborn after the mother's own milk, especially when the baby is a premature or a sick child since this milk has the advantage of protecting against necrotizing enterocolitis. There are currently 13 milk banks in Spain, however this is not sufficient to supply all Spanish neonatal units with donor milk. In order to bring donor milk to the babies in Neonatal Unit of the Regional University Hospital of Malaga, a Satellite Centre (CS) was created in 2012, depending on the Milk Bank of Virgen de las Nieves Hospital in Granada. AIM: Assessing the efficiency of a SC compared to an independent milk bank. METHOD: A study of cost minimization is used for the analysis. The cost of the implementation of the SC is calculated and compared to the cost of the implementation of the Milk Bank of Virgen de las Nieves of Granada. Additionally, the maintenance cost per year of the 2 models is compared, taking into account the running phase from June, 2012 through August 2015 in the SC. RESULTS: A SC implies savings of 88,852 Euro in equipment, and 24,572 Euro per year in maintenance compared to an independent milk bank. CONCLUSIONS: The efficiency of the SC is due to a better use of resources. A distribution network model of donor human milk, consisting of milk banks and SC, makes it possible to equally supply human milk to premature infants with a reduced cost. PMID- 29454740 TI - A rapid point-of-care test for dengue virus-1 based on a lateral flow assay with a near-infrared fluorescent dye. AB - Dengue fever is caused by the dengue virus (DENV), and DENV1 is the prevalent epidemic serotype in south China. A new lateral flow assay (LFA) based on a near infrared (NIR) fluorescent dye was developed to detect anti-DENV1 IgG antibodies. DyLight-800 was used as the marker conjugated to goat anti-human IgG antibodies, and recombinant dengue type 1 envelope protein was used as the capture protein on the test line. Twenty samples from patients infected with DENV1 and 160 negative controls were analyzed using this new NIR-LFA. The results of the NIR-LFA were compared with the results of Panbio Dengue IgG ELISA and the Dengue Duo IgM/IgG Cassette. Nineteen confirmed DENV1-positive samples were identified by NIR-LFA, giving 95% (19/20) sensitivity. No significant differences existed in the results when the 20 primary clinical samples were analyzed using NIR-LFA, Panbio ELISA, and the Dengue Duo Cassette. However, NIR-LFA had a lower limit of detection than IgG ELISA and Duo IgM/IgG Cassette did when analyzing a 2-fold dilution series of the 19 samples positively identified by NIR-LFA. When incorporated with an NIR POCT device, the new NIR-LFA was rapid, easy to use, and highly sensitive in detecting DENV1, and has potential for application to clinical diagnosis. PMID- 29454739 TI - Spanish and Catalan translation, cultural adaptation and validation of the Picker Patient Experience Questionnaire-15. AB - OBJECTIVE: To develop and test a culturally adapted core set of questions to measure patients' experience after in-patient care. MATERIAL AND METHODS: Following the methodology recommended by international guides, a basic set of patient experience questions, selected from Picker Institute Europe questionnaires (originally in English), was translated to Spanish and Catalan. Acceptability, construct validity and reliability of the adapted questionnaire were assessed via a cross-sectional validation study. The inclusion criteria were patients aged >18 years, discharged within one week to one month prior to questionnaire sending and whose email was available. Day cases, emergency department patients and deaths were excluded. Invitations were sent by email (N=876) and questionnaire was fulfilled through an online platform. An automatic reminder was sent 5 days later to non-respondents. RESULTS: A questionnaire, in Spanish and Catalan, with adequate conceptual and linguistic equivalence was obtained. Response rate was 44.4% (389 responses). The correlation matrix was factorable. Four factors were extracted with Parallel Analysis, which explained 43% of the total variance. First factor: information and communication received during discharge. Second factor: low sensitivity attitudes of professionals. Third factor: assessment of communication of medical and nursing staff. Fourth factor: global items. The value of the Cronbach alpha was 0.84, showing a high internal consistency. CONCLUSIONS: The obtained experience patient questionnaire, in Spanish and Catalan, shows good results in the psychometric properties evaluated and could be a useful tool to identify opportunities for health care improvement in our context. Email could become a feasible tool for greater patient participation in everything that concerns his health. PMID- 29454741 TI - Exploiting or overcoming the dome trap for enhanced oral immunization and drug delivery. AB - The microfold cells (M cells) residing in the outmost follicle-associated epithelia (FAE) of Peyer's patches capture foreign particles and hand over to sub FAE lymphatics, where the particles are retained and disposed subsequently. A concept of "dome trap" is proposed to highlight the significance of this mechanism. For oral immunization, it is better to exploit the entrapment capacity to maximize immune response, whereas for drug delivery it is better to overcome the dome trap to transport drugs into the systemic circulation. By optimizing the size, shape, surface charges and surface properties of particles, either oral immunization or drug delivery can be potentially enhanced. PMID- 29454742 TI - Tumor target amplification: Implications for nano drug delivery systems. AB - Tumor cells overexpress surface markers which are absent from normal cells. These tumor-restricted antigenic signatures are a fundamental basis for distinguishing on-target from off-target cells for ligand-directed targeting of cancer cells. Unfortunately, tumor heterogeneity impedes the establishment of a solid expression pattern for a given target marker, leading to drastic changes in quality (availability) and quantity (number) of the target. Consequently, a subset of cancer cells remains untargeted during the course of treatment, which subsequently promotes drug-resistance and cancer relapse. Since target inefficiency is only problematic for cancer treatment and not for treatment of other pathological conditions such as viral/bacterial infections, target amplification or the generation of novel targets is key to providing eligible antigenic markers for effective targeted therapy. This review summarizes the limitations of current ligand-directed targeting strategies and provides a comprehensive overview of tumor target amplification strategies, including self amplifying systems, dual targeting, artificial markers and peptide modification. We also discuss the therapeutic and diagnostic potential of these approaches, the underlying mechanism(s) and established methodologies, mostly in the context of different nanodelivery systems, to facilitate more effective ligand-directed cancer cell monitoring and targeting.

AB - The genetic etiology for obesity-related traits remains elusive.

These findings provide new information on obesity etiology and suggest potential anti-obesity therapeutic strategies. PMID- 29454746 TI - Phosphodiesterase inhibition and modulation of corticostriatal and hippocampal circuits: Clinical overview and translational considerations. AB - The corticostriatal and hippocampal circuits contribute to the neurobiological underpinnings of several neuropsychiatric disorders, including Alzheimer's disease, Parkinson's disease and schizophrenia. Based on biological function, these circuits can be clustered into motor circuits, associative/cognitive circuits and limbic circuits. Together, dysfunctions in these circuits produce the wide range of symptoms observed in related neuropsychiatric disorders. Intracellular signaling in these circuits is largely mediated through the cyclic adenosine monophosphate (cAMP)/protein kinase A (PKA) pathway with an additional role for the cyclic guanosine monophosphate (cGMP)/ protein kinase G (PKG) pathway, both of which can be regulated by phosphodiesterase inhibitors (PDE inhibitors). Through their effects on cAMP response element-binding protein (CREB) and Dopamine- and cAMP-Regulated PhosphoProtein MR 32 kDa (DARPP-32), cyclic nucleotide pathways are involved in synaptic transmission, neuron excitability, neuroplasticity and neuroprotection. In this clinical review, we provide an overview of the current clinical status, discuss the general mechanism of action of PDE inhibitors in relation to the corticostriatal and hippocampal circuits and consider several translational challenges. PMID- 29454747 TI - Plasminogen Activator Inhibitor-1 Reduces Tissue-Type Plasminogen Activator Dependent Fibrinolysis and Intrahepatic Hemorrhage in Experimental Acetaminophen Overdose. AB - Acetaminophen (APAP)-induced liver injury in mice is associated with activation of the coagulation cascade and deposition of fibrin in liver. Plasminogen activator inhibitor-1 (PAI-1) is an important physiological inhibitor of tissue type plasminogen activator (tPA) and plays a critical role in fibrinolysis. PAI-1 expression is increased in both experimental APAP-induced liver injury and patients with acute liver failure. Prior studies have shown that PAI-1 prevents intrahepatic hemorrhage and mortality after APAP challenge, but the downstream mechanisms are not clear. We tested the hypothesis that PAI-1 limits liver related morbidity after APAP challenge by reducing tPA-dependent fibrinolysis. Compared with APAP-challenged (300 mg/kg) wild-type mice, hepatic deposition of cross-linked fibrin was reduced, with intrahepatic congestion and hemorrhage increased in PAI-1-deficient mice 24 hours after APAP overdose. Administration of recombinant wild-type human PAI-1 reduced intrahepatic hemorrhage 24 hours after APAP challenge in PAI-1-/- mice, whereas a mutant PAI-1 lacking antiprotease function had no effect. Of interest, tPA deficiency alone did not affect APAP induced liver damage. In contrast, fibrinolysis, intrahepatic congestion and hemorrhage, and mortality driven by PAI-1 deficiency were reduced in APAP-treated tPA-/-/PAI-1-/- double-knockout mice. The results identify PAI-1 as a critical regulator of intrahepatic fibrinolysis in experimental liver injury. Moreover, the results suggest that the balance between PAI-1 and tPA activity is an important determinant of liver pathology after APAP overdose. PMID- 29454748 TI - Fatty Acid Binding Protein 4 (FABP4) Overexpression in Intratumoral Hepatic Stellate Cells within Hepatocellular Carcinoma with Metabolic Risk Factors. AB - Metabolic syndrome is a newly identified risk factor for hepatocellular carcinoma (HCC); however, tumor-specific biomarkers still remain unclear. We performed cross-species analysis to compare gene signatures of HCC from human patients and melanocortin 4 receptor-knockout mice, which develop HCC with obesity, insulin resistance, and dyslipidemia. Unsupervised hierarchical clustering and principle component analysis of 746 differentially expressed orthologous genes classified HCC of 152 human patients and melanocortin 4 receptor-knockout mice into two distinct subgroups, one of which included mouse HCC and was causatively associated with metabolic risk factors. Nine genes commonly overexpressed in human and mouse metabolic disease-associated HCC were identified; fatty acid binding protein 4 (FABP4) was remarkably enriched in intratumoral activated hepatic stellate cells (HSCs). Subclones constitutively expressing FABP4 were established from a human HSC cell line in which expression levels of inflammatory chemokines, including IL-1A and IL-6, were up-regulated through NF-kappaB nuclear translocation, resulting in recruitment of macrophages. An immunohistochemical validation study of 106 additional human HCC samples indicated that FABP4 positive HSCs were distributed in tumors of 38 cases, and the FABP4-high group consisted of patients with nonviral and nonalcoholic HCC (P = 0.027) and with multiple metabolic risk factors (P < 0.001) compared with the FABP4-low group. Thus, FABP4 overexpression in HSCs may contribute to hepatocarcinogenesis in patients with metabolic risk factors by modulation of inflammatory pathways. PMID- 29454749 TI - Microbiota-Derived Indole Metabolites Promote Human and Murine Intestinal Homeostasis through Regulation of Interleukin-10 Receptor. AB - Interactions between the gut microbiota and the host are important for health, where dysbiosis has emerged as a likely component of mucosal disease. The specific constituents of the microbiota that contribute to mucosal disease are not well defined. The authors sought to define microbial components that regulate homeostasis within the intestinal mucosa. Using an unbiased, metabolomic profiling approach, a selective depletion of indole and indole-derived metabolites was identified in murine and human colitis. Indole-3-propionic acid (IPA) was selectively diminished in circulating serum from human subjects with active colitis, and IPA served as a biomarker of disease remission. Administration of indole metabolites showed prominent induction of IL-10R1 on cultured intestinal epithelia that was explained by activation of the aryl hydrocarbon receptor. Colonization of germ-free mice with wild-type Escherichia coli, but not E. coli mutants unable to generate indole, induced colonic epithelial IL-10R1. Moreover, oral administration of IPA significantly ameliorated disease in a chemically induced murine colitis model. This work defines a novel role of indole metabolites in anti-inflammatory pathways mediated by epithelial IL-10 signaling and identifies possible avenues for utilizing indoles as novel therapeutics in mucosal disease. PMID- 29454750 TI - A Newly Discovered Antifibrotic Pathway Regulated by Two Fatty Acid Receptors: GPR40 and GPR84. AB - Numerous clinical conditions can lead to organ fibrosis and functional failure. There is a great need for therapies that could effectively target pathophysiological pathways involved in fibrosis. GPR40 and GPR84 are G protein coupled receptors with free fatty acid ligands and are associated with metabolic and inflammatory disorders. Although GPR40 and GPR84 are involved in diverse physiological processes, no evidence has demonstrated the relevance of GPR40 and GPR84 in fibrosis pathways. Using PBI-4050 (3-pentylbenzeneacetic acid sodium salt), a synthetic analog of a medium-chain fatty acid that displays agonist and antagonist ligand affinity toward GPR40 and GPR84, respectively, we uncovered an antifibrotic pathway involving these receptors. In experiments using Gpr40- and Gpr84-knockout mice in models of kidney fibrosis (unilateral ureteral obstruction, long-term post-acute ischemic injury, and adenine-induced chronic kidney disease), we found that GPR40 is protective and GPR84 is deleterious in these diseases. Moreover, through binding to GPR40 and GPR84, PBI-4050 significantly attenuated fibrosis in many injury contexts, as evidenced by the antifibrotic activity observed in kidney, liver, heart, lung, pancreas, and skin fibrosis models. Therefore, GPR40 and GPR84 may represent promising molecular targets in fibrosis pathways. We conclude that PBI-4050 is a first-in-class compound that may be effective for managing inflammatory and fibrosis-related diseases. PMID- 29454751 TI - Strain-Dependent Variation in Acute Ischemic Muscle Injury. AB - Limited efficacy of clinical interventions for peripheral arterial disease necessitates a better understanding of the environmental and genetic determinants of tissue pathology. Existing research has largely ignored the early skeletal muscle injury response during hind limb ischemia (HLI). We compared the hind limb muscle response, after 6 hours of ischemia, in two mouse strains that differ dramatically in their postischemic extended recovery: C57BL/6J and BALB/cJ. Perfusion, measured by laser Doppler and normalized to the control limb, differed only slightly between strains after HLI (<12% across all measures). Similar (<10%) effect sizes in lectin-perfused vessel area and no differences in tissue oxygen saturation measured by reflectance spectroscopy were also found. Muscles from both strains were functionally impaired after HLI, but greater muscle necrosis and loss of dystrophin-positive immunostaining were observed in BALB/cJ muscle compared with C57BL/6J. Muscle cell-specific dystrophin loss and reduced viability were also detected in additional models of ischemia that were independent of residual perfusion differences. Our results indicate that factors other than the completeness of ischemia alone (ie, background genetics) influence the magnitude of acute ischemic muscle injury. These findings may have implications for future development of therapeutic interventions for limb ischemia and for understanding the phasic etiology of chronic and acute ischemic muscle pathophysiology. PMID- 29454752 TI - Effects of 5-Hydroxytryptamine Class 2 Receptor Antagonists on Bronchoconstriction and Pulmonary Remodeling Processes. AB - Serotonin [5-hydroxytryptamine (5-HT)] is associated with several chronic pulmonary diseases, recognizing 5-HT2 receptor antagonists as potential inhibitors of tissue remodeling. However, the effects of 5-HT2 receptors, especially 5-HT2B receptors on airway function and remodeling, are unclear. We investigated the role of 5-HT2B receptors on airway smooth muscle contractility and remodeling processes. Murine precision-cut lung slices were pretreated with 5 HT2B receptor antagonists (EXT5, EXT9, RS 127445, and PRX 08066), as well as ketanserin (5-HT2A/2C receptor antagonist) (1, 10 MUmol/L), before addition of cumulative concentrations of 5-HT to induce bronchoconstriction. Remodeling effects after treatment with 10 MUmol/L 5-HT and 5-HT2 receptor antagonists were further studied in distal lung tissue by examining release of profibrotic transforming growth factor (TGF)-beta1 and proliferation of human bronchial smooth muscle cells (HBSMCs). 5-HT-induced bronchoconstriction was significantly reduced by EXT5, EXT9, and ketanserin, but not by RS 127445 or PRX 08066. The 5 HT2B receptor antagonists significantly reduced TGF-beta1 release. 5-HT, in combination with TGF-beta1, increased proliferation of HBSMCs, a process reduced by EXT5 and EXT9. Our results indicate that EXT5 and EXT9 may relieve bronchoconstriction in murine airways and serve as an add-on effect in attenuating pulmonary remodeling by improving airway function. The antiproliferative effect on HBSMCs and the inhibition of TGF-beta1 release further support a role of 5-HT2B receptors in pathologic remodeling processes. PMID- 29454753 TI - Protein S Exacerbates Chronic Liver Injury and Fibrosis. AB - Protein S is a vitamin K-dependent glycoprotein produced mainly in the liver with anticoagulant, anti-inflammatory, immune-modulatory, and antiapoptotic properties. Protein S exacerbates acute liver injury by prolonging the survival of liver immune cells. However, the effect of protein S on chronic liver injury and fibrosis is unknown. Here, we investigated whether human protein S can affect chronic liver injury and fibrosis. Liver injury/fibrosis was induced by carbon tetrachloride injection in mice overexpressing human protein S and in wild-type mice. Human protein S transgenic mice receiving carbon tetrachloride showed significantly higher circulating levels of liver transaminases, increased liver expression of inflammatory cytokines, significantly more extended liver fibrosis, and areas with DNA breakage after chronic injury compared with wild-type mice. Wild-type mice infused with exogenous human protein S exhibited exacerbated liver injury and increased number of hepatic stellate cells compared with untreated mice. Human protein S inhibited apoptosis and increased Akt pathway activation in hepatic stellate cells. The antiapoptotic activity of protein S may play a role in chronic liver injury and subsequent liver fibrosis. PMID- 29454754 TI - Mutational Analysis of AKT1 and PIK3CA in Intraductal Papillomas of the Breast with Special Reference to Cellular Components. AB - The pathologic feature of intraductal papillomas is defined as a papillary structure composed of a fibrovascular stromal core lined by luminal epithelial cells and myoepithelial cells. We used droplet digital PCR for the mutational analysis of AKT1 (E17K) and PIK3CA (H1047R, E542K, and E545K) in 60 papillomas. AKT1 and PIK3CA mutations were detected in 12 (20%) and 17 (28%) of the papillomas, respectively. In five tumors harboring mutations, mutational analysis of AKT1 or PIK3CA was performed separately using luminal epithelial cells and myoepithelial cells sorted using anti-cytokeratin 19 antibody and anti-alpha smooth muscle actin antibody. The two types of cells from a given papilloma had the identical mutation. Three patients with the PIK3CA mutation-positive papilloma developed breast cancers at the resection site of the papilloma, but none of these subsequent breast cancers had the PIK3CA mutation. These results indicate that a papilloma stems from a bipotent progenitor cell that contains the AKT1 or PIK3CA mutation and proliferates and differentiates to form the papilloma. Papilloma can be a risk factor for developing breast cancer but is unlikely to be its obligate precursor. PMID- 29454755 TI - Evaluation of antidiabetic potential of steroidal alkaloid of Sarcococca saligna. AB - The demand for natural medicines has increased because of their limited adverse effects. The aim of study is to explore the antidiabetic potential of isolated steroidal alkaloid from Sarcococca saligna in streptozotocin induced diabetic rats. To determine the antidiabetic activity of steroidal alkaloids, diabetes was induced in rats by injecting streptozotocin intraperitoneally at a dose of 40 mg/Kg. After a week of STZ injection the treatment were started and the 8th day was considered as the 1st day of treatment and up to four weeks the rats were treated with steroidal alkaloids. Animals were divided into five groups, group 1 considered as a control group by receiving normal saline (1 ml/Kg) twice daily and group 2, 3, 4 were treated with active compound sarcovagine-D, saracodine and holaphylline at the dose of 5 mg/Kg subcutaneously twice a day while group 5 was treated with a standard drug glibenclamide at a dose of 1 mg/Kg/day. The result showed that treated group 2 and 4 reduced the glucose level in blood significantly while group 3 showed moderate glucose reduction. The fructosamine level reduced significantly in treating group 4 from the 2nd week of treatment while group 2 and 3 decreased the level significantly in week 4 in diabetic rats. The treated groups showed gradual decreases the glucose level in 1st and 2nd week of oral glucose tolerance test compared to control group. The group receiving holaphylline (4) and sarcovagine-D (2) showed good improvements in blood lipids while the effect of compound on body weight showed less significant improvement. The present study concluded that steroid alkaloids from isolated Sarcococca saligna possess hypoglycemic effect and improve others diabetes associated complications. Together these finding further research is needed using a range of doses to explore the other possible beneficial effects in diabetes mellitus and its molecular mechanism. PMID- 29454756 TI - Outcomes after acute symptomatic seizures in neonates. AB - Acute symptomatic seizures are a common sign of neurological dysfunction and brain injury in neonates and occur in approximately one to three per 1000 live births. Seizures in neonates are usually a sign of underlying brain injury and, as such, are commonly associated with adverse outcomes. Neurological morbidities in survivors often co-occur; epilepsy, cerebral palsy, and intellectual disability often occur together in the most severely affected children. Risk factors for adverse outcome include prematurity, low Apgar scores, low pH on the first day of life, seizure onset <24 or >72 h after birth, abnormal neonatal neurological examination, abnormal neonatal electroencephalographic background, status epilepticus, and presence and pattern of brain injury (particularly deep gray or brainstem injury). Despite this list of potential indicators, accurate prediction of outcome in a given child remains challenging. There is great need for long-term, multicenter studies to examine risk factors for, and pathogenesis of, adverse outcomes following acute symptomatic seizures in neonates.

AB - PURPOSE: To evaluate clinical, radiologic, and functional outcomes of patients with condylar neck or base fractures treated with open reduction and internal fixation using strut plates. PATIENTS AND METHODS: Thirty patients with 34 condylar neck and base fractures were included in the study. Transoral endoscopically assisted, submandibular, or transparotid approaches were performed. Clinical and radiologic outcomes were evaluated. Functional outcomes were assessed with the Helkimo index in a subgroup of 15 patients. RESULTS: Strut plates were successfully placed in all surgical approaches used in this study. Fracture healing occurred without complications in 33 condylar processes. One plate fracture occurred. In the subgroup, 7 patients had a good functional outcome, 7 had a slightly impaired functional outcome, and 1 patient had a moderately impaired functional outcome. CONCLUSION: Strut plates are appropriate for retromandibular transparotid, endoscopically assisted transoral, or submandibular approaches in the management of condylar neck or base fractures. Intraoperative handling and fitting accuracy of the strut plates are good. Good to slightly impaired functional outcome was observed in a subgroup of patients. PMID- 29454758 TI - Optical fiber tips for biological applications: From light confinement, biosensing to bioparticles manipulation. AB - BACKGROUND: The tip of an optical fiber has been considered an attractive platform in Biology. The simple cleaved end of an optical fiber can be machined, patterned and/or functionalized, acquiring unique properties enabling the exploitation of novel optical phenomena. Prompted by the constant need to measure and manipulate nanoparticles, the invention of the Scanning Near-field Optical Microscopy (SNOM) triggered the optimization and development of novel fiber tip microfabrication methods. In fact, the fiber tip was soon considered a key element in SNOM by confining light to sufficiently small extensions, challenging the diffraction limit. As result and in consequence of the newly proposed "Lab On Tip" concept, several geometries of fiber tips were applied in three main fields: imaging (in Microscopy/Spectroscopy), biosensors and micromanipulation (Optical Fiber Tweezers, OFTs). These are able to exert forces on microparticles, trap and manipulate them for relevant applications, as biomolecules mechanical study or protein aggregates unfolding. SCOPE OF REVIEW: This review presents an overview of the main achievements, most impactful studies and limitations of fiber tip based configurations within the above three fields, along the past 10 years. MAJOR CONCLUSIONS: OFTs could be in future a valuable tool for studying several cellular phenomena such as neurodegeneration caused by abnormal protein fibrils or manipulating organelles within cells. This could contribute to understand the mechanisms of some diseases or biophenomena, as the axonal growth in neurons. GENERAL SIGNIFICANCE: To the best of our knowledge, no other review article has so far provided such a broad view. Despite of the limitations, fiber tips have key roles in Biology/Medicine. PMID- 29454759 TI - Chromosomal numerical aberration pattern in papillary renal cell carcinoma: Review article. AB - Traditionally, papillary renal cell carcinomas (PRCCs) have been divided in two subgroups - type 1 and type 2. Based on recent molecular and genetic developments in the understanding of RCCs, it seems that this traditional classification may not be adequate and that the spectrum of PRCCs is much wider than initially proposed. Small series of distinct types of PRCC which do not fit into the above mentioned categories have been described in the literature. Published studies investigating molecular genetic changes in various types of PRCCs have shown that the molecular genetic features are remarkably heterogeneous across the whole spectrum of PRCCs. Of all PRCC subtypes/variants, PRCC type 1 seems to be a genetically uniform group, while other types showed different degrees of heterogeneity. Among different molecular-genetic features, chromosomal numerical aberration status is one of the most frequently studied features so far. It is becoming more evident that tumor type-specific chromosomal numerical aberration status in PRCCs may not exist. In this review, we present the most current knowledge concerning chromosomal numerical aberration status in PRCCs.

AB - OBJECTIVES: The purpose of this systematic review was to explore the diagnostic accuracy of various cardiovascular magnetic resonance (CMR) index tests for the diagnosis of acute myocarditis in adult patients. BACKGROUND: Acute myocarditis remains one of the most challenging diagnoses in cardiology. CMR has emerged as the diagnostic tool of choice to detect acute myocardial injury and necrosis in patients with suspected myocarditis. METHODS: We considered all diagnostic cohort and case-control studies. We searched MEDLINE, EMBASE, Cochrane Library, SCOPUS, and Web of Science up to April 21, 2017. We used the Quality Assessment of Diagnostic Accuracy Studies-2 tool to assess the quality of included studies. PROSPERO registration number CRD42017055778 was used. RESULTS: Twenty-two studies were included in the systematic review. Because significant heterogeneity exists among the studies, we only present hierarchical receiver operator curves. The areas under the curve (AUC) for each index test were for T1 mapping 0.95 (95% confidence interval [CI]: 0.93 to 0.97), for T2 mapping 0.88 (95% CI: 0.85 to 0.91), for extracellular volume fraction (ECV) 0.81 (95% CI: 0.78 to 0.85), for increased T2 ratio/signal 0.80 (95% CI: 0.76 to 0.83), for late gadolinium enhancement (LGE) 0.87 (95% CI: 0.84 to 0.90), for early gadolinium enhancement (EGE) 0.78 (95% CI: 0.74 to 0.81), and for the Lake Louise criteria (LLC) 0.81 (95% CI: 0.77 to 0.84). Native T1 mapping had superior diagnostic accuracy across all index tests. The AUC of T2 mapping was greater than the AUC of increased T2 ratio/signal and EGE, whereas ECV showed no superiority compared with other index tests. LGE had better diagnostic accuracy compared with the classic CMR index tests, similar accuracy with T2 mapping and ECV, and only T1 mapping surpassed it. CONCLUSIONS: Novel CMR mapping techniques provide high diagnostic accuracies for the diagnosis of acute myocarditis and constitute promising successors of the classic elements of the LLC for routine diagnostic protocols.

BACKGROUND: There is conflicting evidence on the effect of RVD on clinical outcomes after TAVR. METHODS: A total of 1,116 TAVR patients (age 82 +/- 6 years; 51% female) who were consecutively enrolled into a prospective registry underwent detailed pre-operative assessment of right ventricular (RV) function and were dichotomized into 2 groups for the purposes of the present retrospective analysis. RVD was assessed using fractional area change (<35%), tricuspid annular plane systolic excursion (<1.7 cm), and systolic movement of the RV lateral wall by tissue Doppler imaging (<9.5 cm/s). RVD was found in 325 (29.1%) patients. The primary outcome was cardiovascular death at 1 year. RESULTS: After adjustment for comorbidities, patients with RVD had a higher risk of cardiovascular death at 1 year compared with patients with normal RV function (20.1% vs. 7.1%; adjusted hazard ratio [HRadj]: 2.94; 95% confidence interval [CI]: 2.02 to 4.27; p < 0.001). The difference emerged within the first 30 days after TAVR (9.0% vs. 2.2%; HRadj: 4.62; 95% CI: 2.51 to 8.50; p < 0.001). Normalization of RV function after TAVR was found in 57.4% of patients with RVD at baseline. There was a gradient of increasing risk of cardiovascular death among patients with normal RV function, RVD recovery (HRadj: 2.16; 95% CI: 1.16 to 4.02), new RVD (HRadj: 3.93; 95% CI: 2.09 to 7.39), and maintained RVD (HRadj: 8.74; 95% CI: 5.33 to 14.3), respectively. CONCLUSIONS: RVD at baseline was associated with a more than 2-fold increased risk of cardiovascular death at 1 year after TAVR, with a gradient of risk according to RVD recovery.

AB - OBJECTIVES: This study sought to measure early strut coverage in patients receiving drug-eluting stents (DESs) and to explore the feasibility of short-term dual antiplatelet therapy (DAPT) based on the degree of early strut coverage. BACKGROUND: Data for early strut coverage in patients receiving new-generation DESs, and its implications for DAPT continuation were limited. METHODS: A randomized, multicenter trial was conducted in 894 patients treated with DESs. Patients were randomly assigned to everolimus-eluting stent (EES) (n = 444) or biolimus-eluting stent (BES) (n = 450) groups and optical coherence tomography (OCT)-guided (n = 445) or angiography-guided (n = 449) implantation groups using a 2-by-2 factorial design. Early strut coverage was measured as the percentage of uncovered struts on 3-month follow-up OCT examination. The primary outcome was the difference in early strut coverage between EES and BES groups and between OCT and angiography-guided implantation groups. The secondary outcome was a composite of cardiac death, myocardial infarction, stent thrombosis, and major bleeding during the first 12 months post-procedure in patients receiving 3-month DAPT based on the presence of early strut coverage (<=6% uncovered) on 3-month follow-up OCT. RESULTS: Three-month follow-up OCT data were acquired for 779 patients (87.1%). The median percentage of uncovered struts at 3 months was 8.9% and 8.2% in the EES and BES groups, respectively (p = 0.69) and was lower in the OCT-guided group (7.5%) than in the angiography-guided group (9.9%; p = 0.009). Favorable early strut coverage (<=6% uncovered strut) was observed in 320 of 779 patients (41.1%). At 12 months, the composite event rarely occurred in the 3 month (0.3%) or 12-month (0.2%) DAPT groups (p = 0.80). CONCLUSIONS: OCT-guided DES implantation improved early strut coverage compared with angiography-guided DES implantation, with no difference in strut coverage between EES and BES groups. Short-term DAPT may be feasible in selected patients with favorable early strut coverage (Determination of the Duration of the Dual Antiplatelet Therapy by the Degree of the Coverage of The Struts on Optical Coherence Tomography From the Randomized Comparison Between Everolimus-eluting Stents Versus Biolimus A9 eluting Stents [DETECT-OCT]; NCT01752894).

AB - OBJECTIVES: The authors developed a fully automated framework to quantify myocardial blood flow (MBF) from contrast-enhanced cardiac magnetic resonance (CMR) perfusion imaging and evaluated its diagnostic performance in patients. BACKGROUND: Fully quantitative CMR perfusion pixel maps were previously validated with microsphere MBF measurements and showed potential in clinical applications, but the methods required laborious manual processes and were excessively time consuming. METHODS: CMR perfusion imaging was performed on 80 patients with known or suspected coronary artery disease (CAD) and 17 healthy volunteers. Significant CAD was defined by quantitative coronary angiography (QCA) as >=70% stenosis. Nonsignificant CAD was defined by: 1) QCA as <70% stenosis; or 2) coronary computed tomography angiography as <30% stenosis and a calcium score of 0 in all vessels. Automatically generated MBF maps were compared with manual quantification on healthy volunteers. Diagnostic performance of the automated MBF pixel maps was analyzed on patients using absolute MBF, myocardial perfusion reserve (MPR), and relative measurements of MBF and MPR. RESULTS: The correlation between automated and manual quantification was excellent (r = 0.96). Stress MBF and MPR in the ischemic zone were lower than those in the remote myocardium in patients with significant CAD (both p < 0.001). Stress MBF and MPR in the remote zone of the patients were lower than those in the normal volunteers (both p < 0.001). All quantitative metrics had good area under the curve (0.864 to 0.926), sensitivity (82.9% to 91.4%), and specificity (75.6% to 91.1%) on per-patient analysis. On a per-vessel analysis of the quantitative metrics, area under the curve (0.837 to 0.864), sensitivity (75.0% to 82.7%), and specificity (71.8% to 80.9%) were good. CONCLUSIONS: Fully quantitative CMR MBF pixel maps can be generated automatically, and the results agree well with manual quantification. These methods can discriminate regional perfusion variations and have high diagnostic performance for detecting significant CAD.

AB - OBJECTIVES: The purpose of this study was to evaluate the feasibility of imaging apoptosis in experimental ischemia-reperfusion model by technetium-99m (99mTc) labeled Duramycin, and compare it to an established tracer, 99mTc-labeled Annexin V, which has a relative disadvantage of high radiation burden to nontarget organs. BACKGROUND: During apoptosis, the cell membrane phospholipids phosphatidylserine (PS) and phosphatidylethanolamine (PE) are exposed and can be targeted by Annexin-V and Duramycin, respectively, for in vivo imaging. Identification of a reversible cell death process should permit therapeutic intervention to help reduce myocyte loss and left ventricle dysfunction. METHODS: In a 40-min left coronary artery ischemia-reperfusion model in 17 rabbits, 7 mCi of 99mTc-labeled Duramycin (n = 10), 99mTc-linear Duramycin (a negative tracer control; n = 3), or 99mTc-Annexin-V (a positive tracer-control; n = 4) were intravenously administered 30 min after reperfusion. Of the 10 Duramycin group animals, 4 animals were treated with an antiapoptotic agent, minocycline at the time of reperfusion. In vivo and ex vivo micro-single-photon emission computed tomography (MUSPECT) and micro-computed tomography (MUCT) imaging was performed 3 h after reperfusion, followed by quantitative assessment of tracer uptake and pathological characterization. Fluorescent Duramycin and Annexin-V were injected in 4 rats to visualize colocalization in infarct areas in a 40-min left coronary artery occlusion and 30-min reperfusion model. RESULTS: Intense uptake of Duramycin and Annexin-V was observed in the apical (infarcted) areas. The percent injected dose per gram uptake of Duramycin in apical region (0.751 +/- 0.262%) was significantly higher than remote area in same animals (0.045 +/- 0.029%; p < 0.01). Duramycin uptake was insignificantly lower than Annexin-V uptake (1.23 +/- 0.304%; p > 0.01) but demonstrated substantially lower radiation burden to kidneys (0.358 +/- 0.210% vs. 1.58 +/- 0.316%, respectively; p < 0.001). Fluorescence studies with Duramycin and Annexin V showed colocalization in infarct areas. Minocycline treatment substantially resolved Duramycin uptake (0.354% +/- 0.0624%; p < 0.01). CONCLUSIONS: Duramycin is similarly effective in imaging apoptotic cell death as Annexin-V with lower nontarget organ radiation. Clinical feasibility of apoptosis imaging with a PE-seeking tracer should be tested. PMID- 29454772 TI - Decreased Exercise Tolerance in Stage B Heart Failure: A Shade of Grey. PMID- 29454773 TI - Relationship Between Left Atrial Functional Measures and Incident Atrial Fibrillation in the General Population: The Copenhagen City Heart Study. AB - OBJECTIVES: This study sought to investigate whether left atrial (LA) functional measures predict atrial fibrillation (AF) in the general population. BACKGROUND: Increasing evidence suggests LA functional measures are predictors of AF in several patient groups. METHODS: In a community-based cohort study, approximately 2,000 individuals underwent a transthoracic echocardiogram. Conventional echocardiographic measures and extended LA measures, including the minimal and maximal LA volumes (LAVmin and LAVmax, respectively) and left atrial emptying fraction (LAEF), were performed. The endpoint was incident AF, and participants with known AF were excluded, which left 1,951 for inclusion. RESULTS: Over 11.0 years of follow-up, 184 (9.4%) developed AF. Those who developed AF had significantly larger LA volumes and lower LAEF than participants free of AF. These LA measures were univariable predictors of AF (LAVmax hazard ratio [HR]: 1.10 [95% confidence interval (CI): 1.08 to 1.12] per 1-ml increase, p < 0.001; LAVmin HR: 1.14 [95% CI: 1.12 to 1.16] per 1-ml increase, p < 0.001; LAEF HR: 1.03 [95% CI: 1.02 to 1.04] per percent decrease, p < 0.001). All LA measures remained predictors independent of clinical risk scores, with LAVmin providing the highest C-statistics when added to these risk scores (C-statistic for CHADS2 0.728 vs. CHADS2 + LAVmin 0.778; C-statistic for CHARGE-AF 0.815 vs. CHARGE-AF + LAVmin 0.830). However, hypertension modified the relationship between the measures of LA function (both LAVmin and LAEF) and risk of AF (p for interaction < 0.001), which was not the case for LAVmax (p = 0.22). The measures of LA function mainly provided prognostic information regarding risk of AF in participants without hypertension. Even when we restricted our analysis to individuals without hypertension and nondilated LA (LAVmax<34 ml/m2), the LAVmin and LAEF remained significantly independent predictors of AF after multivariable adjustments (LAVmin HR: 1.12 [95% CI: 1.01 to 1.24], p = 0.028, and LAEF HR: 1.03 [95% CI: 1.00 to 1.06], p = 0.021, respectively). CONCLUSIONS: LA functional measures predict AF in the general population and provide prognostic information incremental to clinical risk scores. In individuals without hypertension and nondilated LA, these measures indicate an increased risk of AF. PMID- 29454775 TI - Left Ventricular Dysfunction and Exercise Capacity Trajectory: Implications for Subclinical Heart Failure Staging Criteria. AB - OBJECTIVES: This study aimed to determine the association of stage B heart failure (SBHF) and its constituent left ventricular (LV) abnormalities with trajectory of exercise capacity over time, and assess whether this association is modified by reversion of these LV abnormalities to normal. BACKGROUND: The LV abnormalities of SBHF may coincide with a reduction in exercise capacity that precedes the overt exercise intolerance of clinical heart failure (HF). Determining the predictive capacity of established and novel SBHF criteria for exercise capacity decline may improve HF risk stratification. METHODS: LV structure/function (echocardiography) and exercise capacity (6-minute walk distance [6MWD]) were assessed at baseline and 3-year follow-up in 268 patients from the NIL-CHF (Nurse-led Intervention for Less Chronic Heart Failure) study (all stage A [SAHF] or SBHF). Changes (Delta) in 6MWD were compared between SAHF and SBHF and across each of 4 constituent components of SBHF: LV hypertrophy, regional wall motion abnormality(ies) (RWMA), left ventricular systolic dysfunction (LVSD) (ejection fraction <45%) and elevated early diastolic filling/annular velocity ratio (E/e' >= 15). RESULTS: Delta6MWD was similar in those with SAHF (n = 141) and SBHF (n = 127; -5 m [95% confidence interval (CI): 21 to +11 m]; covariate-adjusted). However, within the setting of SBHF there was substantive heterogeneity; that is, reductions in 6MWD were observed with persistent elevated E/e' (-34 m [95% CI: -62 to -6 m]) and persistent LVSD (-41 m [95% CI: -74 to -8 m]), but not with LV hypertrophy (+17 m [95% CI: -15 to +49 m) or RWMA (+5 m [-27 to +36 m]), nor in patients whose elevated E/e' or LVSD reverted to normal by 3 years (p > 0.10). CONCLUSIONS: Elevated E/e' is associated with a similar degree of exercise capacity decline to LVSD, supporting that both LV functional criteria be considered in distinguishing SBHF from SAHF. That reversion of either manifestation of LV dysfunction was associated with preserved exercise capacity advocates targeting of these factors by HF preventive interventions. PMID- 29454774 TI - Incremental Diagnostic Value of Stress Computed Tomography Myocardial Perfusion With Whole-Heart Coverage CT Scanner in Intermediate- to High-Risk Symptomatic Patients Suspected of Coronary Artery Disease. AB - OBJECTIVES: The goal of this study was to evaluate the diagnostic accuracy of stress computed tomography myocardial perfusion (CTP) for the detection of functionally significant coronary artery disease (CAD) by using invasive coronary angiography (ICA) plus invasive fractional flow reserve (FFR) as the reference standard in consecutive intermediate- to high-risk symptomatic patients. BACKGROUND: Stress CTP recently emerged as a potential strategy to combine the anatomic and functional evaluation of CAD in a single scan. METHODS: A total of 100 consecutive symptomatic patients scheduled for ICA were prospectively enrolled. All patients underwent rest coronary computed tomography angiography (CTA) followed by stress static CTP with a whole-heart coverage CT scanner (Revolution CT, GE Healthcare, Milwaukee, Wisconsin). Diagnostic accuracy and overall effective dose were assessed and compared versus those of ICA and invasive FFR. RESULTS: The prevalence of obstructive CAD and functionally significant CAD were 69% and 44%, respectively. Coronary CTA alone demonstrated a per-vessel and per-patient sensitivity, specificity, negative predictive value, positive predictive value, and accuracy of 98%, 76%, 99%, 63%, and 83% and of 98%, 54%, 96%, 68%, and 76%, respectively. Combining coronary CTA with stress CTP, per-vessel and per-patient sensitivity, specificity, negative predictive value, positive predictive value, and accuracy were 91%, 94%, 96%, 86%, and 93% and 98%, 83%, 98%, 86%, and 91%, with a significant improvement in specificity, positive predictive value, and accuracy in both models. The mean effective dose for coronary CTA and stress CTP were 2.8 +/- 1.4 mSv and 2.5 +/- 1.1 mSv. CONCLUSIONS: The inclusion of stress CTP for the evaluation of patients with an intermediate to high risk for CAD is feasible and improved the diagnostic performance of coronary CTA for detecting functionally significant CAD. PMID- 29454776 TI - Cardiac Magnetic Resonance Myocardial Feature Tracking for Optimized Prediction of Cardiovascular Events Following Myocardial Infarction. AB - OBJECTIVES: The aims of the study were to assess the prognostic significance of cardiac magnetic resonance myocardial feature tracking (CMR-FT) in a large multicenter study and to evaluate the most potent CMR-FT predictor of hard clinical events following myocardial infarction (MI). BACKGROUND: CMR-FT is a new method that allows accurate assessment of global and regional circumferential, radial, and longitudinal myocardial strain. The prognostic value of CMR-FT in patients with reperfused MI is unknown. METHODS: The study included 1,235 MI patients (n = 795 with ST-segment elevation MI and 440 with non-ST-elevation MI) at 15 centers. All patients were reperfused by primary percutaneous coronary intervention. Central core laboratory-masked analyses were performed to determine left ventricular (LV) circumferential, radial, and longitudinal strain. The primary clinical endpoint of the study was the occurrence of major adverse cardiac events within 12 months after infarction. RESULTS: Patients with cardiovascular events had significantly impaired CMR-FT strain values (p < 0.001 for all). Global longitudinal strain was identified as the strongest CMR-FT parameter of future cardiovascular events and emerged as an independent predictor of poor prognosis following MI even after adjustment for established prognostic markers. Global longitudinal strain provided an incremental prognostic value for all-cause mortality above LV ejection fraction (c-index increase from 0.65 to 0.73; p = 0.04) and infarct size (c-index increase from 0.60 to 0.78; p = 0.002). CONCLUSIONS: CMR-FT is a superior measure of LV function and performance early after reperfused MI with incremental prognostic value for mortality over and above LV ejection fraction and infarct size.

AB - OBJECTIVES: This study sought to establish the diagnostic and prognostic value of a strategy for prediction of abnormal diastolic response to exercise (AbnDR) using clinical, biochemical, and resting echocardiographic markers in dyspneic patients with mild diastolic dysfunction. BACKGROUND: An AbnDR (increase in left ventricular filling pressure) may indicate heart failure with preserved ejection fraction as the cause of symptoms in dyspneic patients, despite a nonelevated noncardiac at rest. However, exercise testing may be inconclusive in patients with noncardiac limitations to physical activity. METHODS: In 171 dyspneic patients (64 +/- 8 years) with suspected heart failure with preserved ejection fraction but resting peak early diastolic mitral inflow velocity/peak early diastolic mitral annular velocity ratio (E/e') <14, a complete echocardiogram (including assessment of myocardial deformation and rotational mechanics) and blood assays for biomarkers were performed. Echocardiography following maximal exercise was undertaken to assess AbnDR (exertional E/e' >14). Patients were followed over 26.2 +/- 4.6 months for endpoints of cardiovascular hospitalization and death. RESULTS: AbnDR was present in 103 subjects (60%). Independent correlates of AbnDR were resting E/e' (odds ratio [OR]: 8.23; 95% confidence interval [CI]: 3.54 to 9.16; p < 0.001), left ventricular untwisting rate (OR: 0.60; 95% CI: 0.42 to 0.86; p = 0.006), and galectin-3-a marker of fibrosis (OR: 1.80; 95% CI: 1.21 to 2.67; p = 0.004). The use of resting E/e' >11.3 and galectin-3 <1.17 ng/ml to select patients for further diagnostic processing would have allowed exercise testing to be avoided in 65% of subjects, at the cost of misclassification of 13%. The composite outcome of cardiovascular hospitalization or death occurred in 47 patients (27.5%). The predictive value of an AbnDR response and the combined strategy (resting echocardiography and galectin-3 or exercise testing in case of an inconclusive first step) showed similar event prediction (36 vs. 34; p = 0.95). CONCLUSIONS: The implementation of a 2-step algorithm (echocardiographic evaluation of resting E/e' followed by the assessment of galectin-3) may improve the diagnosis and prognostic assessment of individuals with suspected heart failure with preserved ejection fraction who are unable to perform a diagnostic exercise test. PMID- 29454784 TI - Coronary Artery Calcium Scores and Atherosclerotic Cardiovascular Disease Risk Stratification in Smokers: MESA. AB - OBJECTIVES: This study assessed the utility of the pooled cohort equation (PCE) and/or coronary artery calcium (CAC) for atherosclerotic cardiovascular disease (ASCVD) risk assessment in smokers, especially those who were lung cancer screening eligible (LCSE). BACKGROUND: The U.S. Preventive Services Task Force recommended and the Centers for Medicare & Medicaid Services currently pays for annual screening for lung cancer with low-dose computed tomography scans in a specified group of cigarette smokers. CAC can be obtained from these low-dose scans. The incremental utility of CAC for ASCVD risk stratification remains unclear in this high-risk group. METHODS: Of 6,814 MESA (Multi-Ethnic Study of Atherosclerosis) participants, 3,356 (49.2% of total cohort) were smokers (2,476 former and 880 current), and 14.3% were LCSE. Kaplan-Meier, Cox proportional hazards, area under the curve, and net reclassification improvement (NRI) analyses were used to assess the association between PCE and/or CAC and incident ASCVD. Incident ASCVD was defined as coronary death, nonfatal myocardial infarction, or fatal or nonfatal stroke. RESULTS: Smokers had a mean age of 62.1 years, 43.5% were female, and all had a mean of 23.0 pack-years of smoking. The LCSE sample had a mean age of 65.3 years, 39.1% were female, and all had a mean of 56.7 pack-years of smoking. After a mean of 11.1 years of follow-up 13.4% of all smokers and 20.8% of LCSE smokers had ASCVD events; 6.7% of all smokers and 14.2% of LCSE smokers with CAC = 0 had an ASCVD event during the follow-up. One SD increase in the PCE 10-year risk was associated with a 68% increase risk for ASCVD events in all smokers (hazard ratio: 1.68; 95% confidence interval: 1.57 to 1.80) and a 22% increase in risk for ASCVD events in the LCSE smokers (hazard ratio: 1.22; 95% confidence interval: 1.00 to 1.47). CAC was associated with increased ASCVD risk in all smokers and in LCSE smokers in all the Cox models. The C-statistic of the PCE for ASCVD was higher in all smokers compared with LCSE smokers (0.693 vs. 0.545). CAC significantly improved the C-statistics of the PCE in all smokers but not in LCSE smokers. The event and nonevent net reclassification improvements for all smokers and LCSE smokers were 0.018 and 0.126 versus 0.16 and -0.196, respectively. CONCLUSIONS: In this well characterized, multiethnic U.S. cohort, CAC was predictive of ASCVD in all smokers and in LCSE smokers but modestly improved discrimination over and beyond the PCE. However, 6.7% of all smokers and 14.2% of LCSE smokers with CAC = 0 had an ASCVD event during follow-up. PMID- 29454786 TI - Rhinovirus respiratory tract infection in hospitalized adult patients is associated with TH2 response irrespective of asthma. AB - OBJECTIVES: We assessed the immunological response of hospitalized adult patients with rhinovirus infection, including critically-ill patients. METHODS: The differential white blood cell (WBC) count and the levels of 29 plasma cytokines/chemokines were compared between 50 adult hospitalized patients with rhinovirus infection and 100 age-matched controls with influenza virus infection. RESULTS: The demographics and comorbidities were similar between rhinovirus and influenza patients, but severe disease was more common for the rhinovirus cohort. Rhinovirus patients had significantly higher WBC counts than influenza patients, especially for eosinophil (P = 3.1 * 10-8). The level of the TH2 cytokine IL-5 was significantly higher among rhinovirus patients, while the levels of 9 other cytokines/chemokines were significantly lower among rhinovirus patients. The levels of CXCL-10 (IP-10), CCL-2 (MCP-1), IFN-alpha2, IFN-gamma, IL-10, and IL-15 remained significantly lower among rhinovirus patients after correction for multiple comparisons. Notably, CXCL-10 had the highest area under the receiver operating characteristic curve (AUC) in differentiating rhinovirus from influenza patients (AUC, 0.918). In the patient subgroup without asthma, the difference in the WBC count and cytokine/chemokine levels between rhinovirus and influenza patients remained statistically significant. CONCLUSIONS: Rhinovirus infection was characterized by a prominent TH2 response, even in patients without asthma. CXCL-10 (IP-10) is a potential biomarker in differentiating rhinovirus from influenza infection. PMID- 29454785 TI - Lymphoid tissue inducer-A divergent member of the ILC family. AB - Innate lymphoid cells (ILCs) that are capable of producing effector cytokines reminiscent of CD4+ T helper (Th) cells during infections and tissue inflammations have drawn much attention in the immunology field in recent years. Within the ILCs, the lymphoid tissue inducer (LTi) cells that play a critical role in lymphoid organogenesis were identified long before the establishment of the ILC concept. LTi cells, developed and functioning mainly at the fetal stage, and LTi-like cells, presumably generated during the adulthood, are regarded as a subset of type 3 ILCs (ILC3s) because they express the ILC3 lineage-defining transcription factor RORgammat, and like other ILC3s, can produce an ILC3 signature cytokine IL-22 and initiate protective immune responses against extracellular bacteria. However, LTi/LTi-like cells have a unique gene expression pattern, and they develop from a progenitor that is distinct from the progenitor of all other ILCs and the progenitor of conventional natural killer (cNK) cells. There are also several other unique features of LTi/LTi-like cells comparing to non-LTi ILC3s. In addition to their classical function in lymphoid organogenesis, LTi/LTi-like cells also have specialized functions in association with the adaptive immune system, which include their effects on T and B cell development, activation and function. In this review, we summarize these specific features of LTi/LTi-like cells and propose that these cells should be considered as a separated innate lymphoid lineage in parallel with other non-LTi ILCs and cNK cells. PMID- 29454788 TI - Advances and Challenges in Endoscopic Training. AB - One of the challenges of the current era is ensuring that endoscopic training is accomplished effectively in the face of multiple competing demands. As health care delivery evolves, with rising patient complexity and increasing productivity requirements, there is mounting pressure on the time available for training in the clinical setting. The practice of endoscopy itself continues to expand to include increasingly complex procedures (eg, therapeutic endoscopic ultrasound, endoscopic submucosal dissection, and peroral endoscopic myotomy) that require dedicated endoscopy training. The rapid pace of progress in the field of endoscopy means that the demand for endoscopy training is not limited to the formal period of training, but instead spans the spectrum to include physicians already in practice. In light of recent advances in our understanding of endoscopy training, this review will serve to highlight the current state of affairs with respect to endoscopic training and how we can consider approaching these challenges. PMID- 29454787 TI - Trans-envelope multidrug efflux pumps of Gram-negative bacteria and their synergism with the outer membrane barrier. AB - Antibiotic resistance is a serious threat to public health. Significant efforts are currently directed toward containment of the spread of resistance, finding new therapeutic options concerning resistant human and animal pathogens, and addressing the gaps in the fundamental understanding of mechanisms of resistance. Experimental data and kinetic modeling revealed a major factor in resistance, the synergy between active efflux and the low permeability barrier of the outer membrane, which dramatically reduces the intracellular accumulation of many antibiotics. The structural and mechanistic particularities of trans-envelope efflux pumps amplify the effectiveness of cell envelopes as permeability barriers. An important feature of this synergism is that efflux pumps and the outer membrane barriers are mechanistically independent and select antibiotics based on different physicochemical properties. The synergism amplifies even weak polyspecificity of multidrug efflux pumps and creates a major hurdle in the discovery and development of new therapeutics against Gram-negative pathogens. PMID- 29454789 TI - Less Is More: A Minimalist Approach to Endoscopy. AB - A substantial literature documents inappropriate usage of gastrointestinal endoscopy in a variety of clinical settings. Overusage of endoscopy appears to be common, and 30% or more of procedures performed in some clinical settings have questionable indications. The potential reasons for overuse of endoscopy are multiple, and include cancer phobia, fear of medical malpractice litigation, profit motive, the investigation of "incidentalomas" found on other imaging, and underappreciation of the delayed harms of endoscopy, among other reasons. Clinical guidelines, which should limit overuse of endoscopy, may instead serve to promote it, if authors opt to be "conservative," recommending endoscopy in situations of unclear utility. Several strategies may decrease overuse of endoscopy, including careful attention to risk stratification when choosing patients to screen, adherence to guidelines for surveillance intervals for colonoscopy, the use of quality indicators to identify outliers in endoscopy utilization, and education on appropriate indications and the risks of overuse at the medical student, residency, and fellowship levels.

AB - BACKGROUND & AIMS: Long non-coding RNAs (lncRNAs) are expressed in tissue specific pattern, but it is not clear how these are regulated. We aimed to identify squamous cell carcinoma (SCC)-specific lncRNAs and investigate mechanisms that control their expression and function. METHODS: We studied expression patterns and functions of 4 SCC-specific lncRNAs. We obtained 113 esophageal SCC (ESCC) and matched non-tumor esophageal tissues from a hospital in Shantou City, China, and performed quantitative reverse transcription polymerase chain reaction assays to measure expression levels of LINC01503. We collected clinical data from patients and compared expression levels with survival times. LINC01503 was knocked down using small interfering RNAs and oligonucleotides in TE7, TE5, and KYSE510 cell lines and overexpressed in KYSE30 cells. Cells were analyzed by chromatin immunoprecipitation sequencing, luciferase reporter assays, colony formation, migration and invasion, and mass spectrometry analyses. Cells were injected into nude mice and growth of xenograft tumors was measured. LINC01503 interaction with proteins was studied using fluorescence in situ hybridization, RNA pulldown, and RNA immunoprecipitation analyses. RESULTS: We identified a lncRNA, LINC01503, which is regulated by a super enhancer and is expressed at significantly higher levels in esophageal and head and neck SCCs than in non-tumor tissues. High levels in SCCs correlated with shorter survival times of patients. The transcription factor TP63 bound to the super enhancer at the LINC01503 locus and activated its transcription. Expression of LINC01503 in ESCC cell lines increased their proliferation, colony formation, migration, and invasion. Knockdown of LINC01503 in SCC cells reduced their proliferation, colony formation, migration, and invasion, and the growth of xenograft tumors in nude mice. Expression of LINC01503 in ESCC cell lines reduced ERK2 dephosphorylation by DUSP6, leading to activation of ERK signaling via MAPK. LINC01503 disrupted the interaction between EBP1 and the p85 subunit of PI3K, increasing AKT signaling. CONCLUSIONS: We identified an lncRNA, LINC01503, which is increased in SCC cells compared with non-tumor cells. Increased expression of LINC01503 promotes ESCC cell proliferation, migration, invasion, and growth of xenograft tumors. It might be developed as a biomarker of aggressive SCCs in patients. PMID- 29454791 TI - Endoscopic Management of Transmural Defects, Including Leaks, Perforations, and Fistulae. AB - Transmural defects of the gastrointestinal tract can be classified into 3 distinct entities-leak, perforation, and fistula. Each arises from different mechanisms and is managed accordingly. Leaks occur most often after surgery, while perforations occur most often after flexible endoscopic maneuvers. Fistulae arise from a variety of mechanisms, such as an evolution from surgical leaks, as well as from specific disease states. Endoscopic management plays a vital role in the treatment of transmural defects as long as the region of interest can be accessed with the appropriate endoscopic accessories. Endoscopic approaches can be broadly classified into those that provide closure and those that provide diversion of luminal contents. With advances in technology, a myriad of devices and accessories are available that allow a tailored approach. Endoscopic approaches to leaks, perforations, and fistulae are discussed in this review. PMID- 29454792 TI - Clinical and Genomic Correlates of Neutrophil Reactive Oxygen Species Production in Pediatric Patients With Crohn's Disease. AB - BACKGROUND & AIMS: Individuals with monogenic disorders of phagocyte function develop chronic colitis that resembles Crohn's disease (CD). We tested for associations between mutations in genes encoding reduced nicotinamide adenine dinucleotide phosphate (NADPH) oxidases, neutrophil function, and phenotypes of CD in pediatric patients. METHODS: We performed whole-exome sequence analysis to identify mutations in genes encoding NADPH oxidases (such as CYBA, CYBB, NCF1, NCF2, NCF4, RAC1, and RAC2) using DNA from 543 pediatric patients with inflammatory bowel diseases. Blood samples were collected from an additional 129 pediatric patients with CD and 26 children without IBD (controls); we performed assays for neutrophil activation, reactive oxygen species (ROS) production, and bacteria uptake and killing. Whole-exome sequence analysis was performed using DNA from 46 of the children with CD to examine associations with NADPH gene mutations; RNA sequence analyses were performed using blood cells from 46 children with CD to test for variations in neutrophil gene expression associated with ROS production. RESULTS: We identified 26 missense mutations in CYBA, CYBB, NCF1, NCF2, and NCF4. Patients with CD who carried mutations in these genes were 3-fold more likely to have perianal disease (P = .0008) and stricturing complications (P = .002) than children with CD without these mutations. Among patients with CD with none of these mutations, 9% had undergone abdominal surgery; among patients with mutations in these NADPH oxidase genes, 31% had undergone abdominal surgery (P = .0004). A higher proportion of neutrophils from children with CD had low ROS production (47%) than from controls (15%) among the 129 patients tested for ROS (P = .002). Minor alleles of the NADPH genes were detected in 7% of children with CD whose neutrophils produced normal levels of ROS vs 38% of children whose neutrophils produced low levels of ROS (P = .009). Neutrophils that produced low levels of ROS had specific alterations in genes that regulate glucose metabolism and antimicrobial responses. CONCLUSIONS: We identified missense mutations in genes that encode NADPH oxidases in children with CD; these were associated with a more aggressive disease course and reduced ROS production by neutrophils from the patients. PMID- 29454794 TI - HCV Genotype 6a Escape From and Resistance to Velpatasvir, Pibrentasvir, and Sofosbuvir in Robust Infectious Cell Culture Models. AB - BACKGROUND & AIMS: Chronic liver diseases caused by hepatitis C virus (HCV) genotype 6 are prevalent in Asia, and millions of people require treatment with direct-acting antiviral regimens, such as NS5A inhibitor velpatasvir combined with the NS5B polymerase inhibitor sofosbuvir. We developed infectious cell culture models of HCV genotype 6a infection to study the effects of these inhibitors and the development of resistance. METHODS: The consensus sequences of strains HK2 (MG717925) and HK6a (MG717928), originating from serum of patients with chronic HCV infection, were determined by Sanger sequencing of genomes amplified by reverse-transcription polymerase chain reaction. In vitro noninfectious full-length clones of these 6a strains were subsequently adapted in Huh7.5 cells, primarily by using substitutions identified in JFH1-based Core-NS5A and Core-NS5B genotype 6a recombinants. We studied the efficacy of NS5A and NS5B inhibitors in concentration-response assays. We examined the effects of long-term culture of Huh7.5 cells incubated with velpatasvir and sofosbuvir singly or combined following infection with passaged full-length HK2 or HK6a recombinant viruses. Resistance-associated substitutions (RAS) were identified by Sanger and next-generation sequencing, and their effects on viral fitness and in drug susceptibility were determined in reverse-genetic experiments. RESULTS: Adapted full-length HCV genotype 6a recombinants HK2cc and HK6acc had fast propagation kinetics and high infectivity titers. Compared with an HCV genotype 1a recombinant, HCV genotype 6a recombinants of strains HK2 and HK6a were equally sensitive to daclatasvir, elbasvir, velpatasvir, pibrentasvir, and sofosbuvir, but less sensitive to ledipasvir, ombitasvir, and dasabuvir. Long-term exposure of HCV genotype 6a-infected Huh7.5 cells with a combination of velpatasvir and sofosbuvir resulted in clearance of the virus, but the virus escaped the effects of single inhibitors via emergence of the RAS L31V in NS5A (conferring resistance to velpatasvir) and S282T in NS5B (conferring resistance to sofosbuvir). Engineered recombinant genotype 6a viruses with single RAS mediated resistance to velpatasvir or sofosbuvir. HCV genotype 6a viruses with RAS NS5A-L31V or NS5B S282T were however, able to propagate and escape in Huh7.5 cells exposed to the combination of velpatasvir and sofosbuvir. Further, HCV genotype 6a with NS5A L31V was able to propagate and escape in the presence of pibrentasvir with emergence of NS5A-L28S, conferring a high level of resistance to this inhibitor. CONCLUSIONS: Strains of HCV genotype 6a isolated from patients can be adapted to propagate in cultured cells, permitting studies of the complete life cycle for this important genotype. The combination of velpatasvir and sofosbuvir is required to block propagation of original HCV genotype 6a, which quickly becomes resistant to single inhibitors via the rapid emergence and persistence of RAS. These features of HCV genotype 6a could compromise treatment. PMID- 29454795 TI - Advances in CRC Prevention: Screening and Surveillance. AB - Colorectal cancer (CRC) is among the most commonly diagnosed cancers and causes of death from cancer across the world. CRC can, however, be detected in asymptomatic patients at a curable stage, and several studies have shown lower mortality among patients who undergo screening compared with those who do not. Using colonoscopy in CRC screening also results in the detection of precancerous polyps that can be directly removed during the procedure, thereby reducing the incidence of cancer. In the past decade, convincing evidence has appeared that the effectiveness of colonoscopy as CRC prevention tool is associated with the quality of the procedure. This review aims to provide an up-to-date overview of recent efforts to improve colonoscopy effectiveness by enhancing detection and improving the completeness and safety of resection of colorectal lesions. PMID- 29454793 TI - P300 Acetyltransferase Mediates Stiffness-Induced Activation of Hepatic Stellate Cells Into Tumor-Promoting Myofibroblasts. AB - BACKGROUND & AIMS: Hepatic stellate cells (HSCs) contribute to desmoplasia and stiffness of liver metastases by differentiating into matrix-producing myofibroblasts. We investigated whether stiffness due to the presence of tumors increases activation of HSCs into myofibroblasts and their tumor-promoting effects, as well as the role of E1A binding protein p300, a histone acetyltransferase that regulates transcription, in these processes. METHODS: HSCs were isolated from liver tissues of patients, mice in which the p300 gene was flanked by 2 loxP sites (p300F/F mice), and p300+/+ mice (controls). The HSCs were placed on polyacrylamide gels with precisely defined stiffness, and their activation (differentiation into myofibroblasts) was assessed by immunofluorescence and immunoblot analyses for alpha-smooth muscle actin. In HSCs from mice, the p300 gene was disrupted by cre recombinase. In human HSCs, levels of p300 were knocked down with small hairpin RNAs or a mutant form of p300 that is not phosphorylated by AKT (p300S1834A) was overexpressed. Human HSCs were also cultured with inhibitors of p300 (C646), PI3K signaling to AKT (LY294002), or RHOA (C3 transferase) and effects on stiffness-induced activation were measured. RNA sequencing and chromatin immunoprecipitation-quantitative polymerase chain reaction were used to identify HSC genes that changed expression levels in response to stiffness. We measured effects of HSC-conditioned media on proliferation of HT29 colon cancer cells and growth of tumors following subcutaneous injection of these cells into mice. MC38 colon cancer cells were injected into portal veins of p300F/Fcre and control mice, and liver metastases were measured. p300F/Fcre and control mice were given intraperitoneal injections of CCl4 to induce liver fibrosis. Liver tissues were collected and analyzed by immunofluorescence, immunoblot, and histology. RESULTS: Substrate stiffness was sufficient to activate HSCs, leading to nuclear accumulation of p300. Disrupting p300 level or activity blocked stiffness-induced activation of HSCs. In HSCs, substrate stiffness activated AKT signaling via RHOA to induce phosphorylation of p300 at serine 1834; this caused p300 to translocate to the nucleus, where it up regulated transcription of genes that increase activation of HSCs and metastasis, including CXCL12. MC38 cells, injected into portal veins, formed fewer metastases in livers of p300F/Fcre mice than control mice. Expression of p300 was increased in livers of mice following injection of CCl4; HSC activation and collagen deposition were reduced in livers of p300F/Fcre mice compared with control mice. CONCLUSIONS: In studies of mice, we found liver stiffness to activate HSC differentiation into myofibroblasts, which required nuclear accumulation of p300. p300 increases HSC expression of genes that promote metastasis. PMID- 29454796 TI - Endoscopic Myotomy for Foregut Motility Disorders. AB - Peroral endoscopic myotomy (POEM) is an advanced endoscopic procedure classically performed for the treatment of achalasia. The procedure is based on principles of submucosal endoscopy and is composed of a mucosal incision, submucosal tunneling, myotomy, and mucosal closure. Multiple published studies that collectively include more than 6000 patients reported clinical success in more than 80% to 90% of patients. Recent literature also suggested durability of response over a medium-term follow-up. POEM is associated with a low rate of adverse events when performed by experienced operators. Gastroesophageal reflux is not infrequent after POEM but does not seem significantly different from reflux that occurs after Heller myotomy. POEM also seems to be effective in the treatment of spastic esophageal disorders (eg, jackhammer and diffuse esophageal spasm). Last, the role of gastric POEM (G-POEM) in the treatment of gastroparesis has been investigated in recent studies with promising results. PMID- 29454798 TI - Functional Bowel Disorders. PMID- 29454799 TI - Identification of genomic variants causing sperm abnormalities and reduced male fertility. AB - Whole genome sequencing has identified millions of bovine genetic variants; however, there is currently little understanding about which variants affect male fertility. It is imperative that we begin to link detrimental genetic variants to sperm phenotypes via the analysis of semen samples and measurement of fertility for bulls with alternate genotypes. Artificial insemination (AI) bulls provide a useful model system because of extensive fertility records, measured as sire conception rates (SCR). Genetic variants with moderate to large effects on fertility can be identified by sequencing the genomes of fertile and subfertile or infertile sires identified with high or low SCR as adult AI bulls or yearling bulls that failed Breeding Soundness Evaluation. Variants enriched in frequency in the sequences of subfertile/infertile bulls, particularly those likely to result in the loss of protein function or predicted to be severely deleterious to genes involved in sperm protein structure and function, semen quality or sperm morphology can be designed onto genotyping assays for validation of their effects on fertility. High throughput conventional and image-based flow cytometry, proteomics and cell imaging can be used to establish the functional effects of variants on sperm phenotypes. Integrating the genetic, fertility and sperm phenotype data will accelerate biomarker discovery and validation, improve routine semen testing in bull studs and identify new targets for cost-efficient AI dose optimization approaches such as semen nanopurification. This will maximize semen output from genetically superior sires and will increase the fertility of cattle. Better understanding of the relationships between male genotype and sperm phenotype may also yield new diagnostic tools and treatments for human male and idiopathic infertility. PMID- 29454797 TI - Alterations in Intestinal Microbiota Lead to Production of Interleukin 17 by Intrahepatic gammadelta T-Cell Receptor-Positive Cells and Pathogenesis of Cholestatic Liver Disease. AB - BACKGROUND & AIMS: Variants at the ABCB4 or MDR2 locus, which encodes a biliary transport protein, are associated with a spectrum of cholestatic liver diseases. Exacerbation of liver disease has been linked to increased hepatic levels of interleukin (IL) 17, yet the mechanisms of this increase are not understood. We studied mice with disruption of Mdr2 to determine how defects in liver and alteration in the microbiota contribute to production of IL17 by intrahepatic gammadelta T cells. METHODS: We performed studies with Mdr2-/- and littermate FVB/NJ (control) mice. IL17 was measured in serum samples by an enzyme-linked immunosorbent assay. Mice were injected with neutralizing antibodies against the gammadelta T-cell receptor (TCR; anti-gammadelta TCR) or mouse IL17A (anti IL17A). Livers were collected and bacteria were identified in homogenates by culture procedures; TCRgammadelta+ cells were isolated by flow cytometry. Fecal samples were collected from mice and analyzed by 16S ribosomal DNA sequencing. Cells were stimulated with antibodies or bacteria, and cytokine production was measured. We obtained tissues from 10 patients undergoing liver transplantation for primary sclerosing cholangitis or chronic hepatitis C virus infection. Tissues were analyzed for cytokine production by gammadelta TCR+ cells. RESULTS: Mdr2-/- mice had collagen deposition around hepatic bile ducts and periportal bridging fibrosis with influx of inflammatory cells and increased serum levels of IL17 compared with control mice. Administration of anti-IL17A reduced hepatic fibrosis. Livers from Mdr2-/- mice had increased numbers of IL17A+ gammadeltaTCR+ cells-particularly of IL17A+ Vgamma6Jgamma1 gammadelta TCR+ cells. Fecal samples from Mdr2-/- mice were enriched in Lactobacillus, and liver tissues were enriched in Lactobacillus gasseri compared with control mice. Mdr2-/- mice also had increased intestinal permeability. The gammadelta TCR+ cells isolated from Mdr2-/ livers produced IL17 in response to heat-killed L gasseri. Intraperitoneal injection of control mice with L gasseri led to increased serum levels of IL17 and liver infiltration by inflammatory cells; injection of these mice with anti gammadelta TCR reduced serum level of IL17. Intravenous injections of Mdr2-/- mice with anti-gammadelta TCR reduced fibrosis; liver levels of IL17, and inflammatory cells; and serum levels of IL17. gammadeltaTCR+ cells isolated from livers of patients with primary sclerosing cholangitis, but not hepatitis C virus infection, produced IL17. CONCLUSIONS: In Mdr2-/- mice, we found development of liver fibrosis and inflammation to require hepatic activation of gammadelta TCR+ cells and production of IL17 mediated by exposure to L gasseri. This pathway appears to contribute to development of cholestatic liver disease in patients. PMID- 29454800 TI - Remarkable improved electro-Fenton efficiency by electric-field-induced catalysis of CeO2. AB - In this study, we designed a novel combined electro-Fenton system for the treatment of wastewater containing biological recalcitrant using electric-field induced ceria (CeO2) as the synergistic catalysts. It was found that by applying this CeO2 electro-Fenton system, the current efficiency improved from 74.49% to 109.82% within 2.5 min; the removal efficiency for dimethyl phthalate (DMP) increased from 85.5% to 94.9% within 20 min; and the mineralization rate increased from 76.01% to 93.58% after 120 min. The effects of parameters such as the applied potential, electrolyte, and concentration of Fe2+ on the current efficiency were systematically studied. Investigations by LSV, zeta titration, X ray photoelectron spectroscopy (XPS), X-Ray Diffraction (XRD)and electron spin resonance (ESR)revealed the reasons for achieving a current efficiency of over 100% in the CeO2 electro-Fenton system. A mechanism that involved Bronsted acid sites and the redox cycle of sulfate CeO2 was proposed. PMID- 29454801 TI - The influence of Pb addition on the properties of fly ash-based geopolymers. AB - Preventing or reducing negative effects on the environment from the waste landfilling is the main goal defined by the European Landfill Directive. Generally geopolymers can be considered as sustainable binders for immobilization of hazardous wastes containing different toxic elements. In this paper the influence of addition of high amount of lead on structure, strength, and leaching behavior (the effectiveness of Pb immobilization) of fly ash-based geopolymers depending on the geopolymer curing conditions was investigated. Lead was added during the synthesis of geopolymers in the form of highly soluble salt - lead nitrate. Structural changes of geopolymers as a result of lead addition/immobilization were assessed by means of XRD, SEM/EDS, and 29Si MAS NMR analysis. Investigated curing conditions significantly influenced structure, strength and leaching behavior of geopolymers. High addition of lead caused a sizeable decrease in compressive strength of geopolymers and promoted formation of aluminum-deficient aluminosilicate gel (depolymerization of aluminosilicate gel), regardless of the curing conditions investigated. According to the EUWAC limitations, 4% of lead was successfully immobilized by fly ash-based geopolymers cured for 28 days in a humid chamber at room temperature. PMID- 29454802 TI - Vangl2 is essential for myocardial remodeling activated by Wnt/JNK signaling. AB - The Wnt/JNK pathway, responsible for tissue polarity in cardiogenesis in vertebrates, has been shown to play numerous roles during differentiation and development of cardiac myocytes. Van Gogh-like-2 (Vangl2) is a core component that regulates the induction of polarized cellular and tissue morphology during animal development. However, little is known about Wnt/JNK signaling pathway in the process of myocardial remodeling. In present study, we found that activation of Wnt/JNK signaling by Wnt5a stimulates enlargement of cardiomyocyte surface area. The hypertrophic features were inhibited in Vangl2 depleted cells. Meanwhile, Wnt/JNK activation induced cytoskeleton rearrangement but failed to activate these effects in cells lacking Vangl2. Moreover, Wnt/JNK activation significantly increased the cell apoptosis by mediating the mitochondrial permeability transition pore (mPTP) dysfunction, whereas knockdown of Vangl2 partly reversed these effects. These results suggest that activation of Wnt/JNK signaling stimulates myocardial remodeling (cell morphological changes, apoptosis and mitochondrial dysfunction), in which Vangl2 may play an essential role.

PMID- 29454804 TI - Physiological predictors of leptin vary during menses and ovulation in healthy women. AB - Although research has shown interactions between the reproductive system and energy homeostasis, it is not clear how environmental or behavioral factors may factor into these associations. Here we aimed to determine how changes in reproductive state (i.e., phase of the menstrual cycle) and other behavioral and physiological factors may influence leptin levels in healthy women, as well as how sexual activity may play a role in leptin modulation. We collected serum and saliva from 32 healthy women and measured leptin, estradiol, and progesterone. Participants also completed surveys of demographics, health and sexual behaviors, and physical activity. Leptin was predicted by meals per day and missed meals at both menses and ovulation. However, estradiol and physical activity were stronger predictors of leptin at menses, while sexual activity was a stronger predictor of leptin at ovulation. These findings suggest that predictors of serum leptin, and possibly energy storage and expenditure, vary across the menstrual cycle. PMID- 29454806 TI - Oxidative imbalance in mice intoxicated by microcystin-LR can be minimized. AB - Microcystins-LR (MC-LR) is a cyanotoxin produced by cyanobacteria. We evaluated the antioxidant potential of LASSBio-596 (LB-596, inhibitor of phosphodiesterases 4 and 5), per os, and biochemical markers involved in lung and liver injury induced by exposure to sublethal dose of MC-LR. Fifty male Swiss mice received an intraperitoneal injection of 60 MUL of saline (CTRL group, n = 20) or a sublethal dose of MC-LR (40 MUg/kg, TOX group, n = 20). After 6 h the animals received either saline (TOX and CTRL groups) or LB-596 (50 mg/kg, TOX + LASS group, n = 10) by gavage. At 6 h after exposure, respiratory mechanics was evaluated in 10 CTRL and 10 TOX mice: there was a significant increase of all lung mechanics parameters (static elastance, viscoelastic component of elastance and lung resistive and viscoelastic/inhomogeneous pressures) in TOX compared to CTRL. 8 h after saline or MC-LR administration, i.e., 2 h after treatment with LB-596, blood serum levels of alanine aminotransferase and aspartate aminotransferase, activity of superoxide dismutase, catalase, and content of malondialdehyde and carbonyl in lung and liver, NADPH oxidase 2 and 4 mRNA expressions, dual oxidase enzyme activity and H2O2 generation were analyzed in lung homogenates. All parameters were significantly higher in TOX than in the other groups. There was no significant difference between CTRL and TOX + LASS. MC-LR deteriorated lung and liver functions and induced redox imbalance in them, which was prevented by oral administration of LB-596. PMID- 29454805 TI - Mouse preantral follicle growth in 3D co-culture system using human menstrual blood mesenchymal stem cell. AB - Follicle culture provides a condition which can help investigators to evaluate various aspects of ovarian follicle growth and development and impact of different components and supplementations as well as presumably application of follicle culture approach in fertility preservation procedures. Mesenchymal Stem Cells (MSCs), particularly those isolated from menstrual blood has the potential to be used as a tool for improvement of fertility. In the current study, a 3D co culture system with mice preantral follicles and human Menstrual Blood Mesenchymal Stem Cells (MenSCs) using either collagen or alginate beads was designed to investigate whether this system allows better preantral follicles growth and development. Results showed that MenSCs increase the indices of follicular growth including survival rate, diameter, and antrum formation as well as the rate of in vitro maturation (IVM) in both collagen and alginates beads. Although statistically not significant, alginate was found to be superior in terms of supporting survival rate and antrum formation. Hormone assay demonstrated that the amount of secreted 17 beta-estradiol and progesterone in both 3D systems increased dramatically after 12 days, with the highest levels in system employing MenSCs. Data also demonstrated that relative expression of studied genes increased for Bmp15 and Gdf9 and decreased for Mater when follicles were cultured in the presence of MenSCs. Collectively, results of the present study showed that MenSCs could improve indices of follicular growth and maturation in vitro. Further studies are needed before a clinical application of MenSCs-induced IVM is considered. PMID- 29454807 TI - Characterization of chronic obstructive pulmonary disease prescribing patterns in the United States. AB - BACKGROUND: Chronic obstructive pulmonary disease (COPD) is the third-leading cause of death in the United States. Guideline recommendations for medication therapy include the use of inhaled medications for management of stable COPD. There are limited data available describing prescribing percentages of medications in patients with COPD. AIM: To determine the prescribing percentages of medications for COPD in a national, cross-sectional study. METHODS: This was a national, cross-sectional study using data from the National Ambulatory Medical Care Survey (NAMCS) in 2013. Patients were included if they had an International Classification of Diseases (ICD) 9 code for COPD and were greater than 18 years of age. Data describing patient demographics, provider demographics and prescribed medications were collected. Data were analyzed using sample weights to account for the multi-stage sample design. RESULTS: On weighted analysis, 15,821,000 patient visits were included. Patients were predominantly female, greater than 40 years of age and white, non-Hispanic. The most common provider type was primary care provider. At least one COPD medication was prescribed to 64.8% of included patients. Prescription of short-acting bronchodilators was most common in this cohort and observed at a percentage of 42.5%. A long-acting bronchodilator or inhaled corticosteroid was prescribed to 32.3% of included patients. The most common long-acting bronchodilator used was long-acting beta agonist therapy in 21.3% of patients. CONCLUSION: This study describes patients with COPD from a nationally representative sample. The percentage of maintenance medication prescribing indicates further opportunity for medication optimization in the outpatient setting for patients with COPD. PMID- 29454808 TI - A new multifunctionalized material against multi-drug resistant bacteria and abnormal osteoclast activity. AB - The development of new biomaterials able to favor bone formation and to inhibit bone abnormal resorption is mandatory to face the increasing number of age related musculo-skeletal disorders. Moreover, the increasing antibiotic resistance of clinically important bacteria, which is among the main causes of implant failure, requires new antimicrobial systems. In this study, we prepared multifunctional materials consisting of hydroxyapatite-zoledronate composite crystals decorated with Ag Nanoparticles (AgNPs). Zoledronate, a potent bisphosphonate widely applied for the treatment of pathologies associated to abnormal bone loss, was incorporated into hydroxyapatite up to about 8 wt%. Loading of poly(ethylenimine) - stabilized AgNPs onto the crystals was promoted by zoledronate functionalization and provoked a significant variation of the values of zeta potential. The results of in vitro tests demonstrate that the multifunctional materials combine the beneficial actions of zoledronate and AgNPs. In fact, they improve osteoblast differentiation and activity, whereas they inhibit osteoclastogenesis and osteoclast differentiation, and significantly hinder the growth of multi-drug resistant Gram positive and Gram negative bacteria. As a consequence, they can be exploited both as antiresorptive agents and as antimicrobial materials able to prevent the development of bone-associated infections. PMID- 29454809 TI - The hidden lipoproteome of Staphylococcus aureus. AB - Lipoproteins are attached to the outer leaflet of the membrane by a di- or tri acylglyceryl moiety and are thus positioned in the membrane-cell wall interface. Consequently, lipoproteins are involved in many surface associated functions, including cell wall synthesis, electron transport, uptake of nutrients, surface stress response, signal transduction, and they represent a reservoir of bacterial virulence factors. Inspection of 123 annotated Staphylococcus aureus genome sequences in the public domain revealed that this organism devotes about 2-3% of its coding capacity to lipoproteins, corresponding to about 70 lipoproteins per genome. 60 of these lipoproteins were identified in 95% of the genomes analyzed, which thus constitute the core lipoproteome of S. aureus. 30% of the conserved staphylococcal lipoproteins are substrate-binding proteins of ABC transporters with roles in nutrient transport. With a few exceptions, much less is known about the function of the remaining lipoproteins, representing a large gap in our knowledge of this functionally important group of proteins. Here, we summarize current knowledge, and integrate information from genetic context analysis, expression and regulatory data, domain architecture, sequence and structural information, and phylogenetic distribution to provide potential starting points for experimental evaluation of the biological function of the poorly or uncharacterized lipoproteome of S. aureus. PMID- 29454810 TI - Predictors of functional outcome after hanging injury. AB - PURPOSE: Suicide becomes a serious problem in today's society and hanging is a common method of suicide. We want to find the factors which can predict the final functional outcomes of these cases. METHODS: All patients who presented to Accident and Emergency Department (ED) of the National Cheng Kung University Hospital from 1st January 2005 to 31th December 2013 with a hanging injury were included in this study. All cases were divided into good outcome group and bad outcome group according to Glasgow Outcome Scale (GOS). Data was analyzed by Mann Whitney test and chi-square test. RESULTS: Glasgow Coma Scale (GCS) < 3, pupil dilation and no pupillary light reflex both at the scene and ED were the factors to indicate poor functional outcome. Out-hospital cardiac arrest (OHCA), acidosis (pH < 7.2) and the need for intubation once arriving at ED were also related to poor functional outcome. OHCA cases all had poor functional outcome. CONCLUSION: GCS, pupil size, pupillary light reflex, OHCA and acidosis are useful as prognostic factors. GCS = 3 lead to a very poor outcome. However, the functional outcome seems good in patients with GCS>3. There parameters can help to predict the outcome before treatment. PMID- 29454811 TI - Examining parental monitoring as a moderator of the relationship between depressed mood and alcohol use and problems. AB - BACKGROUND: The comorbidity of depressed mood and college student drinking causes consequences for both the individual and society. Aspects of parenting have been shown to be important for college students' well-being. While some interventions are beginning to address this population, few studies have examined how parental monitoring impacts the relationship between depressed mood, alcohol use, and related consequences. The present study examined whether perceived parental monitoring moderated the relationship between depressed mood and alcohol use and related problems. METHODS: Students (N = 796) completed a survey during the fall semester of their first two years of college at a large, public university assessing drinking and related negative consequences, maternal and paternal monitoring, and depressed mood. RESULTS: Results revealed that maternal and paternal monitoring moderated the relationship between depressed mood and typical weekly drinking, and depressed mood and consequences (i.e., self-perception, self care, blackouts). CONCLUSIONS: Interventions should be tailored to parents based on considerations of both student mental health and alcohol use. PMID- 29454812 TI - Impulsivity-related traits, college alcohol beliefs, and alcohol outcomes: Examination of a prospective multiple mediation model among college students in Spain, Argentina, and USA. AB - OBJECTIVES: The present study examined (both cross-sectionally and prospectively) the mediational role of college alcohol beliefs in the relationship between impulsivity-related traits and alcohol outcomes (i.e., alcohol use and negative consequences) among college student drinkers from the United States (U.S.), Spain, and Argentina. METHOD: A sample of 1429 (U.S. = 733, Spain = 292, Argentina = 404) drinkers (at least one drinking episode within the previous month) completed the baseline survey, and 242 drinkers completed the follow-up. To test study aims, a cross-sectional model was first employed to examine whether the proposed double-mediated paths (i.e., each dimension of impulsivity -> college alcohol beliefs -> alcohol use -> negative alcohol-related consequences) extends across samples with different cultural backgrounds (i.e., structural invariance testing). A longitudinal model was then conducted to assess if college alcohol beliefs prospectively mediate the associations between trait impulsivity and alcohol outcomes. RESULTS: College alcohol beliefs were concurrently and prospectively associated with both greater alcohol use and increased number of negative alcohol-related consequences. These internalized beliefs about college student drinking culture significantly mediated the effects of several distinct impulsivity-related traits on alcohol-related outcomes including urgency (positive and negative), sensation seeking, and perseverance. These findings were invariant across gender and across three countries (Argentina, Spain, and the U.S.). CONCLUSIONS: Our findings highlight the modulatory role of cognitive factors on problematic alcohol use among college students with different cultural backgrounds. Our results suggest that, despite the cultural differences exhibited by these three countries, the unique and mediational effects of college alcohol beliefs appear relatively universal.

AB - AIMS: The present study was divided into two different stages that sought to develop (Stage 1) and validate (Stage 2) the Argentinean-version of the Pregaming Motives Questionnaire (PMQ-Arg), a new, ecologically valid measure to assess pregaming (i.e., the consumption of alcohol prior to attending a social/sporting event where alcohol may or may not be available) motives among Spanish-speaking youth. METHOD: Two separate samples of Argentinian young adults (all last-year pregamers) were recruited by disseminating an invitation through online social networks and e-mail listings. RESULTS: In Stage 1, a total of 635 participants answered an open-ended question about their reasons for pregaming. In Stage 2 (n=361), exploratory factor analysis was conducted with the preliminary set of high-quality, high-frequency pregaming motives that were obtained in Stage 1, yielding a final 23-item measure that was grouped in four factors: (i) Intoxication and Fun, (ii) Gathering and Social Enhancement, (iii) Going with the Flow, and (iv) Beverage Preference. Despite some broad similarities with measures that were developed with U.S. young adults, the present results indicated that the narrow content of some items of the PMQ-Arg were somewhat unique, possibly reflecting cultural differences between the United States and Argentina. The findings supported the adequate reliability, discriminant validity, convergent validity, and criterion-related validity of PMQ-Arg scores. CONCLUSIONS: The findings suggest that the PMQ-Arg meets the psychometric requirements of validity and reliability for its use to assess reasons for pregaming among Spanish speaking youth.

AB - INTRODUCTION: Previous research has shown reductions in cigarette consumption during the pre-quit period of exercise-aided smoking cessation interventions. Smoking topography and sensation patterns during this period is unknown and may provide valuable insight into compensation and cessation readiness. METHODS: Female smokers (N = 236, M age = 43, M cigarettes/day = 17.0) enrolled in an exercise-aided smoking cessation intervention self-reported daily cigarette use and cigarette sensory experiences. Breath carbon monoxide and smoking topography data were collected during the period leading up to the targeted quit date (i.e., baseline, week 1, and week 3), which was set for week 4. RESULTS: Repeated measures ANOVAs revealed that cigarette consumption (p < 0.001, eta = 0.32), carbon monoxide (p < 0.001, eta = 0.14), puff duration (p = 0.01, eta = 0.05), smoking satisfaction (p < 0.001, eta = 0.34), psychological reward (p < 0.001, eta = 0.43), enjoyment of respiratory tract sensations (p < 0.001, eta = 0.29), and craving (p < 0.001, eta = 0.39) decreased, whereas average puff flow (p = 0.01, eta = 0.05) increased. CONCLUSIONS: This is the first study to establish that regular exercise during the pre-quit period served as a conduit for facilitating behavioral and sensory harm reduction with cigarettes. Furthermore, the pattern of change observed between cigarette consumption and smoking topography does not support compensation. These findings imply that female smokers who exercise prior to a quit attempt are in a favourable state to achieve cessation.

AB - The improvement of municipal solid waste (MSW) management in touristic islands has not been sufficiently studied, and by using the Spanish Balearics as a case study, a hybrid methodology has been developed which: (i) identifies the three most influential variables (driving forces) of the MSW generation system through an econometric model based on official historical data for a given period (2000 2014), (ii) develops a System Dynamics (SD) model of the evolution of MSW generation in this archipelago based on the same data and time period, and (iii) forecasts the performance of the MSW management system for a future period (2015 2030). Six different scenarios are considered with varying assumptions, objectives and management policies, while applying Scenario Analysis to the SD model developed. The results show that by maintaining the current policies ("business as usual" BAU scenario) it will be impossible to meet the goals set by the Regional and the Spanish National Plans based on the European MSW Directive. However, by implementing the improvements proposed in the simulated alternative scenarios, the model predicts that by 2030, generation of MSW will have increased by 15% compared to 2014, mainly due to the effect of the Tourist Population which is 37.5% higher than the Resident Population. In addition, for the most optimistic scenario, the amount of MSW sent to landfills would decrease by 40%, and selective collection would increase by 30%, compared to 2014. PMID- 29454816 TI - Optimization of granular waste production based on mechanical properties. AB - Pellet production of food and agricultural wastes is a suitable method to supply livestock feed. Mechanical properties of pellets play an important role in their handling and transportation. In this study, the mechanical properties of pellets made from waste are investigated. After the pelleting process, the pellets were dried with a laboratory convective hot air dryer until reaching a safe moisture content. The effects of feedstock moisture content (0.54, 0.88, and 1.2 kgw kgDM 1), particle size (PS < 0.4, 0.4 < PS<1.2, and 1.2 < PS<2 mm), drying temperature (318, 333, and 348 K) and infrared radiation power of the dryer (0, 500, and 1000 W) on pellet durability, impact resistance, and compressive strength were investigated for two diets. The results showed that the mechanical properties of the pellets increased with decreasing particle size of the raw materials. The feedstock moisture content also affected the durability, impact resistant, and compressive strength of pellets. Moreover, mechanical properties were reduced considerably when the pellets were dried at a high temperature and infrared power. The diet with a lower fat content as well as a lower neutral detergent fiber indicated a higher pellet quality. Furthermore, the combination of raw materials and optimization of pelleting and drying conditions had a significant effect on the quality of the produced pellets.

AB - The management of end-of-life tyres (ELTs) is regulated by several national and international legislations aiming to promote the recovery of materials and energy from this waste. The three main materials used in tyres are considered: rubber (main product), which is currently reused in other closed-loop applications; steel, which is used for the production of virgin materials; and textile fibres (approximately 10% by weight of ELTs), which are mainly incinerated for energy recovery (open-loop scenario). This study aims to propose and validate a new closed-loop scenario for textile fibres based on material reuse for bituminous conglomerates. The final objective is to verify the technical, environmental, financial, and economic feasibility of the proposed treatment process and reuse scenario. After characterization of the textile material, which is required to determine the technological feasibility, a specific process has been developed to clean, compact, and prepare the fibres for subsequent reuse. A life cycle assessment (LCA) has been carried out to quantify the environmental benefits of reusing the fibres. Finally, a cost benefit analysis based on the LCA results was conducted to establish the long-term financial and economic sustainability. From a technological point of view, the tyre textile fibres could be a promising substitute to the reinforcement cellulose commonly used in asphalts as long as the fibres are properly prepared (compaction and pellet production) for application in the standard bituminous conglomerate production process. From an environmental point of view, relevant benefits in terms of global warming potential and acidification potential reduction were observed in comparison with the standard incineration for energy recovery (respectively -86% and -45%). Moreover, the proposed scenario can be considered as financially viable in the medium to long term (cumulative generated cash flow is positive after the 5th year) and economically sustainable (expected net present value of more than ?3,000,000 and economic rate of return of approximately 30%). Finally, the sensitivity and risk analyses show that no specific issues are foreseen for the future implementation in real industrial applications. PMID- 29454818 TI - Comprehensive characterization of printed circuit boards of various end-of-life electrical and electronic equipment for beneficiation investigation. AB - Comprehensive characterization of printed circuit board (PCB) of end-of-life electrical and electronic equipment (EEE) is obligatory for prospective profitable beneficiation. In this study, beneficiation oriented comprehensive characterization of two brands of PCBs each of 16 end-of-life EEE was conducted in terms of their physicochemical characteristics with special emphasis on the content of 16 general elements, 2 precious metals and 15 rare earth elements (REEs). General elements and their highest weight percent composition found in different PCBs of the EEEs were Cu (23% in laptop), Al (6% in computer), Pb (15% in DVD player) and Ba (7% in TV). The high abundant of precious metals such as Au (316 g/ton) and Ag (636 g/ton) in mobile phone and laptop, respectively coupled with rapid obsolescence age makes waste PCBs of information technology and telecommunication equipment the most potent resource reservoir. Additionally, most of the waste PCBs were observed to contain REEs in considerable quantity with Sc up to 31 g/ton and Ce up to 13 g/ton being the major constituents. Comprehensive characterization of waste PCBs therefore will systematically help towards better understanding of e-waste recycling processes for beneficiation purpose and sustainable resource circulation and conservation. PMID- 29454819 TI - Some inferences still take time: Prosody, predictability, and the speed of scalar implicatures. AB - Experimental pragmatics has gained many insights from understanding how people use weak scalar terms (like some) to infer that a stronger alternative (like all) is false. Early studies found that comprehenders initially interpret some without an upper bound, but later results suggest that this inference is sometimes immediate (e.g., Grodner, Klein, Carbary, & Tanenhaus, 2010). The present paper explores whether rapid inferencing depends on the prosody (i.e., summa rather than some of) or predictability of referring expressions (e.g., consistently using some to describe subsets). Eye-tracking experiments examined looks to subsets (2-of-4 socks) and total sets (3-of-3 soccer balls) following some and found early preferences for subsets in predictable contexts but not in less predictable contexts (Experiment 1 and 2). In contrast, there was no reliable prosody effect on inferencing. Changes in predictability did not affect judgments of the naturalness of some, when a discourse context was available (Experiment 3). However, predictable contexts reduced variability in speakers' descriptions of subsets and total sets (Experiment 4). Together, these results demonstrate that scalar inferences are often delayed during comprehension, but reference restriction is rapid when set descriptions can be formulated beforehand.

AB - The role of interleukin-23 is crucial in the pathogenesis of psoriasis, and IL23A, IL12B and IL23R genetic variants have been associated with the disease in genome-wide association studies. In the current paper we have conducted a confirmation study of the abovementioned genetic factors in a case-control analysis of 507 psoriatic patients and 396 controls from a Polish population, and subsequently analyzed the impact of genetic variants on response to topical and NB-UVB therapy in a subset of 306 patients. Case-control analysis revealed an association of IL12B rs3212227 and IL23R rs11209026 minor allele carrier status with reduced odds for psoriasis (OR = 0.66, 95%CI: 0.50-0.87, and OR = 0.41, 95%CI: 0.26-0.67, respectively), while HLA-C*06 allele carriers were more frequent in patients group (OR = 4.56, 95%CI: 3.41-6.10). The studied polymorphic variants of IL12B, IL23A, and IL23R genes did not influence therapy outcome, i.e. there were no significant differences in PASI reduction between patients with different genotypes. However, HLA-C*06 carriers showed poorer response to the applied treatment, when compared to non-carriers. The results of the current study confirm an association between IL12B and IL23R genetic polymorphism and psoriasis vulgaris (with a protective effect of minor alleles). HLA-C*06 carriers show reduced effectiveness of topical/NB-UVB therapy, and that observation could be potentially used in treatment personalization. PMID- 29454822 TI - Premature mortality in single fathers. PMID- 29454821 TI - Mortality in single fathers compared with single mothers and partnered parents: a population-based cohort study. AB - BACKGROUND: Single parent families, including families headed by single fathers, are becoming increasingly common around the world. Previous evidence suggests that single parenthood is associated with adverse health outcomes and increased mortality; however, most studies have focused on single mothers, with little known about the health of single fathers. This study aimed to examine mortality in a large population-based sample of Canadian single fathers compared with single mothers and partnered fathers and mothers. METHODS: We used a representative sample of 871 single fathers, 4590 single mothers, 16 341 partnered fathers, and 18 688 partnered mothers from the Canadian Community Health Survey (cycles 2001-12; earliest survey date: Sept 5, 2000; latest survey date: Dec 24, 2012). We anonymously linked survey participants to health administrative database records to ascertain health status at baseline and mortality from survey date up to Oct 28, 2016. We included individuals who were aged 15 years or older, living in a household with one or more biological or adopted child younger than 25 years, and living in Ontario, and we excluded those who left Ontario during the study period or had data discrepancies. Single parents were defined as those who were divorced, separated, widowed, or single, never-married, and non-cohabitating, and partnered parents were defined as those who were married or common-law partners. We investigated differences in mortality using Cox proportional hazards models with adjustment for sociodemographic, lifestyle, and clinical factors. FINDINGS: Median follow-up was 11.10 years (IQR 7.36-13.54). Mortality in single fathers (5.8 per 1000 person-years) was three times higher than rates in single mothers (1.74 per 1000 person-years) and partnered fathers (1.94 per 1000 person-years). Single fathers had a significantly higher adjusted risk of dying than both single mothers (hazard ratio [HR] 2.49, 95% CI 1.20-5.15; p=0.01) and partnered fathers (2.06, 1.11 3.83; p=0.02). INTERPRETATION: In this first head-to-head comparison of mortality across single and partnered parent groups, we found that single fathers had the least favourable risk factor profile and greatest risk of mortality. Social histories might help physicians identify these high-risk patients. Further work is needed to understand the causes of this high mortality risk and how clinical and public health interventions can improve lifestyle and behavioural risk factors.

AB - The infectious salmon anemia virus (ISAV) is an aquatic pathogen that is a member of the Orthomyxoviridae family with lethal hemorrhagic potential. Although it affects other species of salmonid fish, ISAV only causes disease in Atlantic salmon (Salmo salar) specimens in sea water. In spite of the fact that the virus has been described as enveloped with icosahedral symmetry, viral like particles with anomalous morphology have been observed in field samples, this we have not been able to recover then in adequate quantities for full demonstration. We report a procedure to concentrate and recover these novel forms of the virus, comparing two cell lines from different origins, demonstrating that these forms were preferentially expressed in cells of epithelial origin.

AB - Candida albicans is an emerging multidrug-resistant fungal pathogen representing an important source of invasive disease in humans and generating high healthcare costs worldwide. This fungus is frequently found in different anatomical sites of healthy persons and could induce systemic and superficial infections under optimal environmental conditions. Invasive candidiasis (IC) is an important nosocomial infection with high morbidity and mortality rates in hospitalized children. It represents a major source of prolonged infections in intensive care unit (ICU), particularly in immunosuppressed or elderly patients. Clinical diagnosis of candidiasis could be difficult because of the lack of specific symptoms and clinical signs. Although C. albicans is the most frequently isolated Candida species in IC, non-albicans Candida (NAC) species are also commonly detected. Multilocus enzyme electrophoresis (MLEE), fragment length polymorphism (RFLP), electrophoretic karyotyping (EK), and random amplified polymorphic DNA (RAPD), multilocus sequence typing (MLST) are known as an efficient technique used for molecular typing of Candida species. The efficacy of antifungal treatment against candidiasis has been evaluated and discussed in the context of large epidemiological studies. The present review highlights the etiology, epidemiology, molecular typing, commensalism and virulence factors, along with the appropriate prevention and control strategies regarding this widespread pathogen. PMID- 29454826 TI - Diagnosis, follow-up and management of sleep-disordered breathing in children with osteogenesis imperfecta. AB - OBJECTIVES: Osteogenesis imperfecta (OI) is the most common genetic skeletal disorder. Extraskeletal findings are common but an association with sleep disordered breathing (SDB) has never been described. The aim of this study was to investigate clinical features of children with OI and suspected SDB. METHODS: A retrospective study of clinical records, signs of SDB and polysomnographic recordings of children with OI was performed. We paid particular attention to symptoms that could be associated with SDB in this population - scoliosis, kyphosis, vertebral arthrodesis, chest wall deformities, basilar impression, autonomy - as well as data already known to be associated with obstructive sleep apnea such as body mass index and upper-airway impairment. RESULTS: We reviewed the clinical charts of 188 patients referred to our genetic skeletal disorders reference center for OI. Among the 15 patients (8%) with polysomnographic recordings, 12 (6.4%) had sleep-disordered breathing. We found a negative correlation between the Brief Assessment of Motor Function score and Apnea Hypopnea Index (r=-0.68; p=0.01) and Desaturation Index (r=-0.62; p=0.02). The Apnea Hypopnea Index was higher for non-walkers than walkers (mean [SD]: 6.5 [3.6] vs. 2.4 [1.5]; p=0.02) and with type III versus IV OI. Two patients were started on continuous positive airway pressure ventilation, with clinical improvement. CONCLUSION: For OI children, symptoms suggesting obstructive sleep disorders should be searched for systematically, especially in children with compromised autonomy, high body mass index, trunk deformations, and severe OI type. PMID- 29454827 TI - Development of thermostable amylase enzyme from Bacillus cereus for potential antibiofilm activity. AB - The marine bacterial strain Bacillus cereus was used to produce amylase enzyme and has excellent alkali-stable and thermostable enzymatic activity. The combined effects of pH, temperature and incubation time on amylase activity were studied using response surface methodology. The amylase enzyme activity was also determined in the presence of various metal ions, chelating agents, detergents and the results showed that the maximum enzyme activity was observed in the presence of calcium chloride (96.1%), EDTA (63.4%) and surf excel (90.6%). The amylase enzyme exhibited excellent antibiofilm activity against marine derived biofilm forming bacteria Pseudomonas aeruginosa and Staphylococcus aureus in microtiter plate assay and congo red assay. Light and confocal laser scanning microscopic (CLSM) analysis were also used to confirm the potential biofilm activity of amylase enzyme. The CLSM analysis showed the inhibition of complete biofilm formation on amylase enzyme treated glass surface. Further in vivo toxicity analysis of amylase enzyme was determined against marine organisms Dioithona rigida and Artemia salina. The results showed that there is no morphological changes were observed due to the minimal toxicity of amylase enzyme. Overall these findings suggested that marine bacterial derived amylase enzyme could be developed as potential antibiofilm agent.

The synthesized compounds displayed moderate to good activity. Among these, a coumarin derivative 3k exhibited excellent results (IC50 2.10 +/- 0.004 uM) in comparison to clinical drug acarbose (IC50 37.38 +/- 0.12 uM).

AB - Investigation of the MeOH extract of Betula schmidtii twigs resulted in the isolation and identification of three new triterpenoids (1-3), along with ten known ones (4-13). The structures of new compounds (1-3) were elucidated by spectroscopic methods, including 1D, 2D NMR (1H and 13C NMR, COSY, HSQC, HMBC, and NOESY), HR-MS, and chemical methods. All the isolated compounds were evaluated for their cytotoxicity against A549, SK-OV-3, SK-MEL-2, and HCT-15 cell lines. Compound 11 exhibited potent cytotoxic activities against four cell lines, and compounds 5 and 13 significantly induced nerve growth factor secretion in a C6 rat glioma cell line. Their anti-inflammatory effects were also assessed by measuring nitric oxide production in lipopolysaccharide-activated BV-2 cells. Compounds 7 and 12 displayed potent inhibition of nitric oxide production, without significant cell toxicity. PMID- 29454830 TI - The discrepancy function of NLRC5 isoforms in antiviral and antibacterial immune responses. AB - NOD-like receptors (NLRs) are a family of intracellular pattern recognition receptors (PRRs) that play critical roles in innate immunity against pathogens infection. NLRC5, the largest member of NLR family, has been characterized as a regulator of innate immunity and MHC class I expression. Alternative splicing of NLRC5 is only reported in human and zebrafish. However, the function of NLRC5 isoforms in the innate immune responses remains unknown. In the present study, we report the functional characterization of zfNLRC5a and zfNLRC5d, two splicing isoforms of zebrafish NLRC5. zfNLRC5a and zfNLRC5d are generated by exon skipping, and whose alternative splicing sites exist in the region of LRRs. Fluorescence microscopy showed that zfNLRC5 isoforms were located throughout the entire cell including nuclear staining. The expression of zfNLRC5 isoform was inducible in response to bacterial and viral infections. During SVCV infection, the in vitro and in vivo studies found that zfNLRC5d overexpression increased protection against viral infection; however zfNLRC5a overexpression had no significant effect on antiviral activity. Interestingly, zfNLRC5 isoforms but not zfNLRC5 were involved in transcriptional regulation of TLRs and NF-kappaB signaling. Overexpression of zfNLRC5 isoforms also contributed to negative regulation of antibacterial immune response, with the decreased expression of nfkbiaa (IkappaBalpha). All together, these results firstly demonstrate the function of NLRC5 isoforms in antiviral and antibacterial immune responses both in vitro and in vivo. PMID- 29454831 TI - Characterisation of major histocompatibility complex class I transcripts in an Australian dragon lizard. AB - Characterisation of squamate major histocompatibility complex (MHC) genes has lagged behind other taxonomic groups. MHC genes encode cell-surface glycoproteins that present self- and pathogen-derived peptides to T cells and play a critical role in pathogen recognition. Here we characterise MHC class I transcripts for an agamid lizard (Ctenophorus decresii) and investigate the evolution of MHC class I in Iguanian lizards. An iterative assembly strategy was used to identify six full length C. decresii MHC class I transcripts, which were validated as likely to encode classical class I MHC molecules. Evidence for exon shuffling recombination was uncovered for C. decresii transcripts and Bayesian phylogenetic analysis of Iguanian MHC class I sequences revealed a pattern expected under a birth-and death mode of evolution. This work provides a stepping stone towards further research on the agamid MHC class I region. PMID- 29454832 TI - Identification and functional analysis of inhibitor of NF-kappaB kinase (IKK) from Scylla paramamosain: The first evidence of three IKKs in crab species and their expression profiles under biotic and abiotic stresses. AB - IKK (inhibitor of NF-kappaB kinase) is the critical regulator for NF-kappaB (nuclear factor-kappaB) pathway against pathogenic invasion in vertebrates or invertebrates. However, the IKK from crab species has not yet been identified. In the present study, three full-length cDNA sequences of IKKs from mud crab Scylla paramamosain, designated as SpIKKbeta, SpIKKepsilon1 and SpIKKepsilon2, were firstly cloned through RT-PCR and RACE methods. This is also the first report about the identification of two IKKepsilon genes in mud crab and even in crustaceans. The SpIKKbeta cDNA was 2824 bp in length with an open reading frame (ORF) of 2382 bp, which encoded a putative protein of 793 amino acids (aa). The ORF of two SpIKKepsilon isoforms, SpIKKepsilon1 and SpIKKepsilon2, were 2400 bp and 2331 bp in length encoding 799 aa and 776 aa, respectively. The crucial conserved residues and functional domains, including the kinase domains (KDs) and leucine zipper (LZ), were identified in all SpIKKs. Phylogenetic analysis suggested that SpIKKbeta was classified into the IKKs class while SpIKKepsilons could be grouped into the IKK-related kinases class. The qRT-PCR analysis showed that three SpIKKs were constitutively expressed in all tested tissues and the highest expression levels of SpIKKbeta and SpIKKepsilons were all in hemocyte. The gene expression profiles of SpIKKs were distinct when crabs suffered biotic and abiotic stresses including the exposures of Vibrio alginolyticus, poly (I:C), cadmium and air exposure, suggesting that the SpIKKs might play different roles in response to pathogens infections, heavy metal and air exposure. Moreover, IKKs from mud crab can significantly activate mammalian NF-kappaB pathway, suggesting the function of IKKs might be evolutionally well-conserved. Results of the RNAi experiments suggested that SpIKKs might regulate the immune signaling pathway when hemocytes were challenged with V. parahemolyticus or virus-analog poly (I:C). All of these results indicated that the obtained SpIKKs might be involved in stress responses against biotic or abiotic stresses, and it also highlighted their functional conservation in the innate immune system from crustaceans to mammals. PMID- 29454833 TI - Towards resolving the presynaptic NMDA receptor debate. AB - In the classical view, postsynaptic NMDA receptors (NMDARs) trigger Hebbian plasticity via Ca2+ influx. However, unconventional presynaptic NMDARs (preNMDARs) which regulate both long-term and short-term plasticity at several synapse types have also been found. A lack of sufficiently specific experimental manipulations and a poor understanding of how preNMDARs signal have contributed to long-standing controversy surrounding these receptors. Although several prior studies linked preNMDARs to neocortical timing-dependent long-term depression (tLTD), a recent study argues that the NMDARs are actually postsynaptic and signal metabotropically, that is, without Ca2+. Other recent work indicates that, whereas ionotropic preNMDARs signaling controls evoked release, spontaneous release is regulated by metabotropic NMDAR signaling. We argue that elucidating unconventional NMDAR signaling modes-both presynaptically and metabotropically-is key to resolving the preNMDAR debate. PMID- 29454834 TI - Functional implications of inhibitory synapse placement on signal processing in pyramidal neuron dendrites. AB - A rich literature describes inhibitory innervation of pyramidal neurons in terms of the distinct inhibitory cell types that target the soma, axon initial segment, or dendritic arbor. Less attention has been devoted to how localization of inhibition to specific parts of the pyramidal dendritic arbor influences dendritic signal detection and integration. The effect of inhibitory inputs can vary based on their placement on dendritic spines versus shaft, their distance from the soma, and the branch order of the dendrite they inhabit. Inhibitory synapses are also structurally dynamic, and the implications of these dynamics depend on their dendritic location. Here we consider the heterogeneous roles of inhibitory synapses as defined by their strategic placement on the pyramidal cell dendritic arbor. PMID- 29454835 TI - Mast cells signal their importance in health and disease. AB - FcepsilonRI is the primary receptor in mast cells that mediates allergic reactions by inducing rapid release of mediators, an adaptive immune response that might have evolved as a host defense against parasites and venoms. Yet it is apparent that mast cells are also activated through non-IgE receptors, the significance of which is just beginning to be understood. This includes the Mas related G protein-coupled receptor X2, which might contribute to reactions to diverse antimicrobials and polybasic compounds, and the adhesion G protein coupled receptor E2, variants of which are associated with familial vibratory urticaria and are activated by mechanical vibration. Similarly, mast cells have long been recognized as the main repository for histamine, heparin, and proteases. Recent evidence also points to new functions, modes of delivery, and mechanisms of action of mast cell proteases that add new dimensions to the roles of mast cells in human biology. In addition, exposure of mast cells to environmental cues can quantitatively and qualitatively modulate their responses and thus their effect on allergic inflammation. Illustrating this paradigm, we summarize a number of recent studies implicating the injury/tissue damage cytokine IL-33 as a modulator of allergen-induced mast cell responses. We also discuss the discovery of markers associated with transformed mast cells and new potential directions in suppressing mast cell activity.

AB - : For different reasons, street cocaine is often diluted with pharmacologically active substances, the so-called adulterants such as levamisole or hydroxyzine. A controversial debate exists currently on the uptake of adulterants from cocaine preparations and drug-related death. Previous research convincingly argues that serious adverse side effects that affect the central nervous and cardiovascular systems can be a consequence of adulterated cocaine. AIMS: Having identified the presence of adulterants in lung tissue and blood, the concentrations of these substances in brain, an important target location, was of interest. This provides an opportunity to assess their role in cases of drug-related deaths. MATERIALS AND METHODS: We developed and validated a method for the analysis of cocaine, two cocaine metabolites and six adulterants, which can typically be found in cocaine preparations, and one adulterant metabolite in brain tissue by gas chromatography mass spectrometry (GC-MS)1. Ten brain samples which were tested positive for cocaine were analyzed. The homogenized brain tissue was embedded into drying paper for protein precipitation. During a subsequent solid-phase extraction (SPE), the eluate and one of the wash fractions were collected. After derivatization with N-Methyl-N-(trimethylsilyl)trifluoroacetamide (MSTFA) in pyridine and isooctane, the extracts were analyzed by GC-MS. RESULTS AND DISCUSSION: The method was fully validated for cocaine (COC), benzoylecgonine (BZE), ecgonine methyl ester (EME), diltiazem (DIL), hydroxyzine (HYD), and levamisole (LEV) and partly validated for cetirizine (CET), lidocaine (LID), phenacetin (PHE), and procaine (PRO) in brain material. By analyzing post-mortem brain tissue of ten cocaine users, LEV, LID, and HYD as well as PHE were identified in contrast to DIL, PRO, and the HYD metabolite CET. HYD and LEV were found in moderate to high concentrations in some cases. Therefore, it cannot be excluded that they have caused adverse side effects. CONCLUSION: Because adulterants can potentially affect the central nervous and cardiac systems, it is likely that they enhance COC toxicity. PMID- 29454836 TI - Mechanism for initiation of food allergy: Dependence on skin barrier mutations and environmental allergen costimulation. AB - BACKGROUND: Mechanisms for the development of food allergy in neonates are unknown but clearly linked in patient populations to a genetic predisposition to skin barrier defects. Whether skin barrier defects contribute functionally to development of food allergy is unknown. OBJECTIVE: The purpose of the study was to determine whether skin barrier mutations, which are primarily heterozygous in patient populations, contribute to the development of food allergy. METHODS: Mice heterozygous for the filaggrin (Flg)ft and Tmem79ma mutations were skin sensitized with environmental and food allergens. After sensitization, mice received oral challenge with food allergen, and then inflammation, inflammatory mediators, and anaphylaxis were measured. RESULTS: We define development of inflammation, inflammatory mediators, and food allergen-induced anaphylaxis in neonatal mice with skin barrier mutations after brief concurrent cutaneous exposure to food and environmental allergens. Moreover, neonates of allergic mothers have increased responses to suboptimal sensitization with food allergens. Importantly, responses to food allergens by these neonatal mice were dependent on genetic defects in skin barrier function and on exposure to environmental allergens. ST2 blockade during skin sensitization inhibited the development of anaphylaxis, antigen-specific IgE, and inflammatory mediators. Neonatal anaphylactic responses and antigen-specific IgE were also inhibited by oral pre exposure to food allergen, but interestingly, this was blunted by concurrent pre exposure of the skin to environmental allergen. CONCLUSION: These studies uncover mechanisms for food allergy sensitization and anaphylaxis in neonatal mice that are consistent with features of human early-life exposures and genetics in patients with clinical food allergy and demonstrate that changes in barrier function drive development of anaphylaxis to food allergen. PMID- 29454839 TI - Monitoring the extent of vertical and lateral movement of human decomposition products through sediment using cholesterol as a biomarker. AB - Due to the lack of human decomposition research facilities available in different geographical regions, the extent of movement of human decomposition products from a cadaver into various sedimentary environments, in different climates, has not been able to be studied in detail. In our study, a human cadaver was placed on the surface of a designated plot at the Australian Facility for Taphonomic Experimental Research (AFTER), the only human decomposition facility in Australia, where the natural process of decomposition was allowed to progress over 14days in the Australian summer. Sediment columns (approximately 1m deep) were collected at lateral distances of 0.25m, 0.5m, 1.0m and 2.5m in each of four directions from the centre of the torso. Plot elevation and weather data were also collected. Each sediment column was subdivided, dried and homogenised. A sample was isolated from each sediment subdivision, extracted with hexane, and the hexane extract cleaned with citrate buffer (pH 3), filtered and spiked with cholesterol-D7 internal standard. After derivatisation with BSTFA+1% TMCS, cholesterol was monitored in the samples using targeted gas chromatography tandem mass spectrometry analysis. A positive result for decomposition products was given if the cholesterol abundance in the test sample was higher than that detected in the 'control' samples of a similar substrate type collected prior to cadaver placement. Within the confines of the experimental design and the measured parameters, lateral leaching was observed over distances of up to 2.5m from the centre of the torso, which was the maximum distance tested in the study. Vertical leaching was detected to depths of up to 49cm below the ground surface. Such data can aid the development of policies related to plot sizing and sediment renewal and regeneration at other human decomposition facilities and at cemeteries. The density and distribution of cholesterol surrounding the cadaver in this study can also help forensic investigators interpret cases involving remains that have been moved or scavenged. PMID- 29454840 TI - Melanocortin 4 receptor stimulation improves social deficits in mice through oxytocin pathway. AB - Several studies on humans and mice support oxytocin's role in improving social behaviour, but its use in pharmacotherapy presents some important limiting factors. To date, it is emerging a pharmacological potential for melanocortin 4 receptor (MC4R) agonism in social deficits treatment. Recently, we demonstrated that the deletion of the NFKB1 gene, which encodes the p50 NF-kappaB subunit, causes impairment in social behaviours, with reductions in social interactions in mice. In this work, we tested the acute effects of THIQ, a selective melanocortin 4 receptor (MC4R) agonist. THIQ treatment increased social interactions both in wild type and p50-/- mice. In particular, after treatment with THIQ, p50-/- mice showed a prosocial behaviour analogous to that of basal WT mice. Moreover, intranasal treatment with an oxytocin antagonist blocked social interactions induced by THIQ, demonstrating that its prosocial effects are mediated by the oxytocin pathway. The data obtained reinforce using MC4R agonists to ameliorate social impairment in NDDs. PMID- 29454842 TI - Spatial access to food: Retiring the food desert metaphor. AB - The food desert metaphor has been widely used over the past few decades as a way to identify regions as being at risk for having little or no access to healthy food. While the simplicity of the metaphor is attractive, this article argues that its usefulness to researchers interested in understanding the relationship between the geography of healthy food opportunities and dietary behaviours is limited. More nuanced approaches to incorporating geography into food access studies, like including transportation, economic factors, and time use, in addition to considering other dimensions of accessibility, are warranted. PMID- 29454841 TI - Hypocretin/orexin deficiency decreases cocaine abuse liability. AB - Compelling evidence indicates that hypocretin/orexin signaling regulates arousal, stress and reward-seeking behaviors. However, most studies on drug reward-related processes have so far described the effects of pharmacological blockers disrupting hypocretin/orexin transmission. We report here an extensive study on cocaine-related behaviors in hypocretin/orexin-deficient mice (KO) and their heterozygous (HET) and wildtype (WT) littermates. We evaluated behavioral sensitization following repeated administrations and preference for an environment repeatedly paired with cocaine injections (15 mg/kg). Mice were also trained to self-administer cocaine (0.5-1.5 mg/kg/infusion). Our observations show that whereas all mice exhibited quite similar responses to acute administration of cocaine, only Hcrt KO mice exhibited reduced cocaine-seeking behaviors following a period of abstinence or extinction, and reduced cocaine incubation craving. Further, if the present findings confirm that Hcrt deficient mice may display a hypoactive phenotype, possibly linked to a reduced alertness concomitant to a decreased exploration of their environment, hypocretin/orexin defiency did not cause any attentional deficit. We thus report that innate disruption of hypocretin/orexin signaling moderately alters cocaine reward but significantly reduces long-term affective dependence that may explain the lack of relapse for cocaine seeking seen in Hcrt KO mice. Overall, with blunted cocaine intake at the highest concentration and reduced responsiveness to cocaine cues after prolonged abstinence, our findings suggest that hypocretin deficient mice may display signs of resilience to cocaine addiction. PMID- 29454843 TI - Impact of high sucrose diets on the discrimination of spatial and object memories with overlapping features. AB - High sucrose diets (HSDs) have been shown to have detrimental effects on hippocampal dependent memory in rats, including the performance of spatial tasks reliant on pattern separation, a cognitive process involved in minimising interference during memory encoding. As such we sought to investigate the impact of HSDs on object and spatial recognition tasks that varied the cognitive load placed on pattern separation processes. Young male and female rats were 4 weeks old at the start of diet manipulations. Rats in the HSD condition were provided with daily access to 10% sucrose solution for 2 h per day across a 28 d period, during which they were assessed on their performance of memory tasks that varied the similarity of spatial arrangements (Spontaneous Location Recognition, SLR) and object features (Novel Object Recognition, NOR) to determine the effect of HSD on memory encoding processes. Both female and male rats that consumed HSDs were impaired at NOR when objects shared multiple features (s-NOR), however when objects were distinct, novel object recognition was not impacted by HSD consumption. Male rats in the control condition generally outperformed female rats in the SLR task when there were small spatial separations (s-SLR) but not when there were large spatial separations (d-SLR). HSD consumption disrupted performance of d-SLR in female rats, but not male rats. Specific HSD deficits were observed in HSD consuming male rats in the s-SLR task. However, the volume of sucrose consumed differed between sexes, and may have impacted memory differentially. These findings indicate that HSD-induced memory deficits may extend to pattern separation dependent recognition memory mechanisms when objects share overlapping features, and impairments in spatial tasks may be more pronounced in female rats. PMID- 29454846 TI - Comparison of reporting phase III randomized controlled trials of antibiotic treatment for common bacterial infections in ClinicalTrials.gov and matched publications. AB - OBJECTIVES: Discrepancies between ClinicalTrials.gov entries and matching publications were previously described in general medicine. We aimed to evaluate the consistency of reporting in trials addressing systemic antibiotic therapy. METHODS: We searched ClinicalTrials.gov for completed phase III trials comparing antibiotic regimens until May 2017. Matched publications were identified in PubMed. Two independent reviewers extracted data and identified inconsistencies. Reporting was assessed among studies started before and after 1 July 2005, when the International Committee of Medical Journal Editors (ICMJE) required mandatory registration as a prerequisite for considering a trial for publication. RESULTS: Matching publications were identified for 75 (70%) of 107 ClinicalTrials.gov entries. Median time from study completion to publication was 26 months (interquartile range 19-42). Primary outcome definition was inconsistent between ClinicalTrials.gov and publications in seven trials (7/72, 10%) and reporting of the primary outcome timeframe was inconsistent in 14 (14/71, 20%). Secondary outcomes definitions were inconsistent in 36 trials (36/66, 55%). Reporting of inclusion criteria and study timeline were inconsistent in 17% (13/65) and 3% (2/65), respectively. Trials started after July 2005 were significantly less likely to have reporting inconsistencies and were published in higher impact factor journals. CONCLUSIONS: We found a lower inconsistency rate of outcome reporting compared with other medical disciplines. Reporting completeness and consistency were significantly better after July 2005. The ICMJE requirement for mandatory registration was associated with significant improvement in reporting quality in infectious diseases trials. Prolonged time lag to publication and missing data from unpublished trials should raise a discussion on current reporting and publishing procedures. PMID- 29454845 TI - Evaluation of a new multiplex PCR assay (ParaGENIE G-Amoeba Real-Time PCR kit) targeting Giardia intestinalis, Entamoeba histolytica and Entamoeba dispar/Entamoeba moshkovskii from stool specimens: evidence for the limited performances of microscopy-based approach for amoeba species identification. AB - OBJECTIVES: Besides the potential to identify a wide variety of gastrointestinal parasites, microscopy remains the reference standard in clinical microbiology for amoeba species identification and, especially when coupled with adhesin detection, to discriminate the pathogenic Entamoeba histolytica from its sister but non-pathogenic species Entamoeba dispar/Entamoeba moshkovskii. However, this approach is time-consuming, requires a high-level of expertise that can be jeopardized considering the low prevalence of gastrointestinal parasites in non endemic countries. Here, we evaluated the CE-IVD-marked multiplex PCR (ParaGENIE G-Amoeba, Ademtech) targeting E. histolytica and E. dispar/E. moshkovskii and Giardia intestinalis. METHODS: This evaluation was performed blindly on a reference panel of 172 clinical stool samples collected prospectively from 12 laboratories and analysed using a standardized protocol relying on microscopy (and adhesin detection by ELISA for the detection of E. histolytica) including G. intestinalis (n = 37), various amoeba species (n = 55) including E. dispar (n = 15), E. histolytica (n = 5), as well as 17 other gastrointestinal parasites (n = 80), and negative samples (n = 37). RESULTS: This new multiplex PCR assay offers fast and reliable results with appropriate sensitivity and specificity for the detection of G. intestinalis and E. dispar/E. moshkovskii from stools (89.7%/96.9% and 95%/100%, respectively). Detection rate and specificity were greatly improved by the PCR assay, highlighting several samples misidentified by microscopy, including false-negative and false-positive results for both E. dispar/E. moshkovskii and E. histolytica. CONCLUSION: Given the clinical relevance of amoeba species identification, microbiologists should be aware of the limitations of using an algorithm relying on microscopy coupled with adhesin detection by ELISA. PMID- 29454844 TI - The epidemiology of febrile illness in sub-Saharan Africa: implications for diagnosis and management. AB - BACKGROUND: Fever is among the most common symptoms of people living in Africa, and clinicians are challenged by the similar clinical features of a wide spectrum of potential aetiologies. AIM: To summarize recent studies of fever aetiology in sub-Saharan Africa focusing on causes other than malaria. SOURCES: A narrative literature review by searching the MEDLINE database, and recent conference abstracts. CONTENT: Studies of multiple potential causes of fever are scarce, and for many participants the infecting organism remains unidentified, or multiple co infecting microorganisms are identified, and establishing causation is challenging. Among ambulatory patients, self-limiting arboviral infections and viral upper respiratory infections are common, occurring in up to 60% of children attending health centres. Among hospitalized patients there is a high prevalence of potentially fatal infections requiring specific treatment. Bacterial bloodstream infection and bacterial zoonoses are major causes of fever. In recent years, the prevalence of antimicrobial resistance among bacterial isolates has increased, notably with spread of extended spectrum beta-lactamase-producing Enterobacteriaceae and fluoroquinolone-resistant Salmonella enterica. Among those with human immunodeficiency virus (HIV) infection, Mycobacterium tuberculosis bacteraemia has been confirmed in up to 34.8% of patients with sepsis, and fungal infections such as cryptococcosis and histoplasmosis remain important. IMPLICATIONS: Understanding the local epidemiology of fever aetiology, and the use of diagnostics including malaria and HIV rapid-diagnostic tests, guides healthcare workers in the management of patients with fever. Current challenges for clinicians include assessing which ambulatory patients require antibacterial drugs, and identifying hospitalized patients infected with organisms that are not susceptible to empiric antibacterial regimens. PMID- 29454847 TI - Bejel in Cuba: molecular identification of Treponema pallidum subsp. endemicum in patients diagnosed with venereal syphilis. AB - OBJECTIVES: Bejel, caused by Treponema pallidum subsp. endemicum (TEN), was until now considered as a non-venereal disease endemic in areas with hot and dry climates. This study has identified TEN in clinical samples from Cuban patients previously diagnosed with syphilis. METHODS: We performed sequencing-based molecular typing on 92 samples from Cuban individuals diagnosed with syphilis. Moreover, to differentiate T. pallidum subspecies, multi-locus sequence analysis (MLSA) was designed and was applied to suspicious samples. RESULTS: Nine samples, from six patients, had a nucleotide sequence similarity (at all typing loci) to the Bosnia A genome, which is the infectious agent of bejel. Additionally, MLSA clearly supported a TEN classification for the treponemal samples. Clinical and epidemiological data from the six patients also suggested sexual transmission of bejel as well as the endemicity of this rare treponematosis in Cuba. CONCLUSIONS: Molecular identification of Treponema pallidum subsp. endemicum, the agent of bejel, in Cuban patients diagnosed with syphilis indicates the clear limitations of a diagnosis based exclusively on serology, geographical occurrence, clinical symptoms and anamnestic data. This finding has important implications for Global Public Health Systems, including paradigm changes regarding the location of endemic outbreaks, clinical aspects and transmission of this neglected disease. PMID- 29454848 TI - Multicentre derivation and validation of a simple predictive index for healthcare associated Clostridium difficile infection. AB - OBJECTIVES: Clostridium difficile infection (CDI) is the most common cause of healthcare-associated infections in the United States. Despite well-established risk factors, little research has focused on use of these variables to identify a patient population at high risk for CDI to target with primary prevention strategies. A predictive index for healthcare-associated CDI could improve clinical care and guide research for primary prevention trials. Our objective was to develop a predictive index to identify patients at high risk for healthcare associated CDI. METHODS: We performed a secondary database analysis in a five hospital health system in Houston, Texas. Our cohort consisted of 97 130 hospitalized patients admitted for more than 48 hours between October 2014 and September 2016. The derivation cohort consisted of the initial 80% of admissions (75 545 patients), with the remainder being used in the validation cohort. RESULTS: CDI rates in the derivation and validation cohorts were 1.55% and 1.43%, respectively. Thirty-day predictors of CDI were increased number of high-risk antibiotics, Charlson comorbidity index score, age and receipt of a proton pump inhibitor. These variables were incorporated into a simple risk index with a score range of 0 to 10. The final model demonstrated good discrimination and calibration with the observed CDI incidence ranging from 0.1% to 20.4%. CONCLUSIONS: We developed a predictive index for 30-day risk of healthcare associated CDI using readily available and clinically useful variables. This simple predictive risk index may be used to improve clinical decision making and resource allocation for CDI stewardship initiatives, and guide research design. PMID- 29454849 TI - ESCMID Study Group for Infections in Compromised Hosts (ESGICH) Consensus Document on the safety of targeted and biological therapies: an infectious diseases perspective (Intracellular signaling pathways: tyrosine kinase and mTOR inhibitors). AB - BACKGROUND: The present review is part of the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) Study Group for Infections in Compromised Hosts (ESGICH) Consensus Document on the safety of targeted and biologic therapies. AIMS: To review, from an infectious diseases perspective, the safety profile of therapies targeting different intracellular signaling pathways and to suggest preventive recommendations. SOURCES: Computer-based Medline searches with MeSH terms pertaining to each agent or therapeutic family. CONTENT: Although BCR-ABL tyrosine kinase inhibitors modestly increase the overall risk of infection, dasatinib has been associated with cytomegalovirus and hepatitis B virus reactivation. BRAF/MEK kinase inhibitors do not significantly affect infection susceptibility. The effect of Bruton tyrosine kinase inhibitors (ibrutinib) among patients with B-cell malignancies is difficult to distinguish from that of previous immunosuppression. However, cases of Pneumocystis jirovecii pneumonia (PCP), invasive fungal infection and progressive multifocal leukoencephalopathy have been occasionally reported. Because phosphatidylinositol 3-kinase inhibitors (idelalisib) may predispose to opportunistic infections, anti Pneumocystis prophylaxis and prevention strategies for cytomegalovirus are recommended. No increased rates of infection have been observed with venetoclax (antiapoptotic protein Bcl-2 inhibitor). Therapy with Janus kinase inhibitors markedly increases the incidence of infection. Pretreatment screening for chronic hepatitis B virus and latent tuberculosis infection must be performed, and anti Pneumocystis prophylaxis should be considered for patients with additional risk factors. Cancer patients receiving mTOR inhibitors face an increased incidence of overall infection, especially those with additional risk factors (prior therapies or delayed wound healing). IMPLICATIONS: Specific preventive approaches are warranted in view of the increased risk of infection associated with some of the reviewed agents. PMID- 29454850 TI - Dissemination of Panton-Valentine leukocidin-positive methicillin-resistant Staphylococcus aureus USA300 clone in multiple hospitals in Tokyo, Japan. AB - OBJECTIVES: Panton-Valentine leukocidin (PVL) gene (lukS/F-PV)-positive community acquired methicillin-resistant Staphylococcus aureus (MRSA), particularly the USA300 clone, is a health concern worldwide. Recently, community-acquired MRSA clones have been found to spread and persist in hospital settings. We aimed to investigate the prevalence and molecular epidemiologic features of lukS/F-PV positive MRSA in Japanese hospitals. METHODS: A total of 3433 MRSA isolated from nine hospitals in 2011-2015 were assessed. Molecular epidemiologic analysis performed by staphylococcal cassette chromosome mec typing, PVL typing, arginine catabolic mobile element typing, detection of virulence determinants, multilocus sequence typing, pulsed-field gel electrophoresis and antimicrobial susceptibility testing. RESULTS: The detection rate of lukS/F-PV was increased annually from 0.6% (5/817) in 2011 to 3.1% (17/544) in 2015. Molecular epidemiologic analysis for 64 lukS/F-PV-positive MRSA isolates revealed that 42 isolates (65.6%) were the USA300 clone. Resistance rates of levofloxacin and gentamicin among lukS/F-PV-positive isolates increased annually as a result of increased prevalence of the multidrug-resistant USA300 clone. CONCLUSIONS: This is the first report on dissemination of the USA300 clone and PVL-positive MRSA in multiple Japanese hospitals. Our data strongly suggest that the USA300 clone may become epidemic in Japanese hospitals. PMID- 29454851 TI - Declines in adult blood lead levels in New York City compared with the United States, 2004-2014. AB - OBJECTIVES: To assess changes in lead exposure in the New York City (NYC) adult population over a 10-year period and to contrast changes with national estimates, overall, and by socio-demographics and smoking status. METHODS: We used measurements of blood lead levels (BLLs) from NYC resident adults who participated in the NYC Health and Nutrition Examination Surveys (HANES) in 2004 and 2013-2014. We compared estimates of geometric means (GM), 95th percentiles, and prevalence of BLL >= 5 ug/dL overall and by subgroups over time, with adults who participated in the National HANES (NHANES) 2001-2004 and 2011-2014. RESULTS: The GM BLLs among NYC adults declined from 1.79 ug/dL in 2004 to 1.13 ug/dL in 2013-2014 (P < .0001). The declines over this period ranged from 30.1% to 43.2% across socio-demographic groups and smoking status (P < .0001 for all comparisons), and were slightly greater than declines observed nationally. The drop in prevalence of elevated BLLs (>= 5 ug/dL) was also greater in NYC (4.8 0.5%), compared with NHANES (3.8-2.0%). By 2013-2014, NYC adults with lower annual family income (< $20,000) no longer had higher GM BLLs relative to those with higher incomes (>= $75,000), a disparity improvement not observed nationally. Likewise, GM BLLs and 95th percentiles for non-Hispanic black adults in NYC were lower than GM BLLs for non-Hispanic white adults. Non-Hispanic Asian adults had the highest GM BLLs compared with other racial/ethnic groups, both in NYC in 2013-14 and nationally in 2011-2014 (1.37 ug/dL, P = .1048 and 1.22 ug/dL, P = .0004, respectively). CONCLUSION: The lessening of disparity in lead exposure across income groups and decreasing exposure at the high end of the distribution among non-Hispanic black and Asian adults in NYC suggest that regulatory and outreach efforts have effectively targeted these higher exposure risk groups. However, Asian adults still had the highest average BLL, suggesting a need for enhanced outreach to this group. Local surveillance remains an important tool to monitor BLLs of local populations and to inform initiatives to reduce exposures in those at highest risk. PMID- 29454852 TI - Chronic exposure to inhaled, traffic-related nitrogen dioxide and a blunted cortisol response in adolescents. AB - BACKGROUND: Chronic health effects of traffic-related air pollution, like nitrogen dioxide (NO2), are well-documented. Animal models suggested that NO2 exposures dysregulate cortisol function. OBJECTIVES: We evaluated the association between traffic-related NO2 exposure and adolescent human cortisol concentrations, utilizing measures of the cortisol diurnal slope. METHODS: 140 adolescents provided repeated salivary cortisol samples throughout one day. We built a land use regression model to estimate chronic NO2 exposures based on home and school addresses. We then generated model-based estimates of the association between cortisol and NO2 exposure one year prior to cortisol sampling, examining changes in cortisol diurnal slope. The final model was adjusted other criteria pollutants, measures of psychosocial stress, anthropometry, and other demographic and covariates. RESULTS: We observed a decrease in diurnal slope in cortisol for adolescents exposed to the estimated 75th percentile of ambient NO2 (high exposure) relative to those exposed at the 25th percentile (low exposure). For a highly exposed adolescent, the log cortisol was lower by 0.06 ug/dl at waking (95% CI: -0.15, 0.02), 0.07 ug/dl at 30 min post waking (95% CI: -0.15, 0.02), and higher by 0.05 ug/dl at bedtime (95% CI: 0.05, 0.15), compared to a low exposed adolescent. For an additional interquartile range of exposure, the model based predicted diurnal slope significantly decreased by 0.12 (95% CI: -0.23, 0.01). CONCLUSIONS: In adolescents, we found that increased, chronic exposure to NO2 and the mixture of pollutants from traffic sources was associated with a flattened diurnal slope of cortisol, a marker of an abnormal cortisol response which we hypothesize may be a mechanism through which air pollution may affect respiratory function and asthma in adolescents. PMID- 29454853 TI - The photoprotective and anti-inflammatory activity of red propolis extract in rats. AB - The negative effects triggered by ultraviolet radiation, such as premature aging and carcinogenesis, have motivated several studies on photoprotection. Recent strategies for photoprotection have included the incorporation of natural antioxidant and anti-inflammatory compounds, such as flavonoids, into sunscreens and the oral administration of natural antioxidant extracts. Brazilian Red propolis extract contains isoflavonoids with antioxidant and anti-inflammatory activities. Here, we investigate the photoprotective effects of orally- or topically-administered formulations containing hydroalcoholic extract of red propolis (HERP) in a rodent model. HERP showed markers identified as: daidzein (4.68 MUg/mL), formononetin (31.81 MUg/mL) and biochanin A (9.58 MUg/mL). A fourth peak was found in the chromatogram but was not identified. The antioxidant activity of HERP was calculated to be 3.07 mmol Trolox/g and 2.13 mmol Trolox/g, respectively. Topical HERP exerted a protective action against UVB radiation, which was similar to that exerted by oxybenzone filter. Oral HERP as an adjuvant treatment did not increase sunburn protection. However, the oral administration of HERP presented chemoprotective and anti-inflammatory activity (p < 0.05) similar or better than Polypodium leucotomos oral treatment (positive control). In conclusion, topical administration of HERP has photoprotective activity in a murine model and the mechanisms of protection can be related to the antioxidant and anti-inflammatory characteristics of HERP compounds. PMID- 29454854 TI - ERK1/2 inhibitors: New weapons to inhibit the RAS-regulated RAF-MEK1/2-ERK1/2 pathway. AB - The RAS-regulated RAF-MEK1/2-ERK1/2 signalling pathway is de-regulated in a variety of cancers due to mutations in receptor tyrosine kinases (RTKs), negative regulators of RAS (such as NF1) and core pathway components themselves (RAS, BRAF, CRAF, MEK1 or MEK2). This has driven the development of a variety of pharmaceutical agents to inhibit RAF-MEK1/2-ERK1/2 signalling in cancer and both RAF and MEK inhibitors are now approved and used in the clinic. There is now much interest in targeting at the level of ERK1/2 for a variety of reasons. First, since the pathway is linear from RAF-to-MEK-to-ERK then ERK1/2 are validated as targets per se. Second, innate resistance to RAF or MEK inhibitors involves relief of negative feedback and pathway re-activation with all signalling going through ERK1/2, validating the use of ERK inhibitors with RAF or MEK inhibitors as an up-front combination. Third, long-term acquired resistance to RAF or MEK inhibitors involves a variety of mechanisms (KRAS or BRAF amplification, MEK mutation, etc.) which re-instate ERK activity, validating the use of ERK inhibitors to forestall acquired resistance to RAF or MEK inhibitors. The first potent highly selective ERK1/2 inhibitors have now been developed and are entering clinical trials. They have one of three discrete mechanisms of action - catalytic, "dual mechanism" or covalent - which could have profound consequences for how cells respond and adapt. In this review we describe the validation of ERK1/2 as anti-cancer drug targets, consider the mechanism of action of new ERK1/2 inhibitors and how this may impact on their efficacy, anticipate factors that will determine how tumour cells respond and adapt to ERK1/2 inhibitors and consider ERK1/2 inhibitor drug combinations. PMID- 29454855 TI - Signalling pathways regulating galactosaminoglycan synthesis and structure in vascular smooth muscle: Implications for lipoprotein binding and atherosclerosis. AB - Atherosclerosis commences with the trapping of low density lipoproteins (LDLs) in blood vessels by modified proteoglycans (PGs) with hyperelongated glycosaminoglycan (GAG) chains. GAG chain synthesis and growth factor mediated hyperelongation regulates the composition and size of PGs in a manner that would cause low density lipoprotein (LDLs) retention in vessel wall. Galactosaminoglycans are a class of GAGs, commonly observed on PGs. Multiple enzymes are involved in galactosaminoglycan biosynthesis. Galactosaminoglycan synthesis is regulated by various signalling pathways which are amenable to pharmacological manipulation to treat atherosclerosis. Receptor mediated signalling pathways including protein tyrosine kinase receptors (PTKRs), serine/threonine kinase receptors (S/TKRs) and G-protein coupled receptors (GPCRs) pathways regulate galactosaminoglycan synthesizing enzyme expression. Increased expression of these enzymes modify galactosaminoglycan chain structure by making them hyperelongated. This review focuses on the signalling pathways regulating the expression of genes involved in galactosaminoglycan synthesis and modification. Furthermore, there are multiple other processes for inhibiting the interactions between LDL and galactosaminoglycans such as peptide mimetics of ApoB100 and anti-galactosaminoglycan antibodies and the therapeutic potential of these strategies is also addressed. PMID- 29454856 TI - Nucleosidic DNA demethylating epigenetic drugs - A comprehensive review from discovery to clinic. AB - DNA methylation plays a pivotal role in the etiology of cancer by mediating epigenetic silencing of cancer-related genes. Since the relationship between aberrant DNA methylation and cancer has been understood, there has been an explosion of research at developing anti-cancer therapies that work by inhibiting DNA methylation. From the discovery of first DNA hypomethylating drugs in the 1980s to recently discovered second generation pro-drugs, exceedingly large number of studies have been published that describe the DNA hypomethylation-based anti-neoplastic action of these drugs in various stages of the pre-clinical investigation and advanced stages of clinical development. This review is a comprehensive report of the literature published in past 40 years, on so far discovered nucleosidic DNA methylation inhibitors in chronological order. The review will provide a complete insight to the readers about the mechanisms of action, efficacy to demethylate and re-express various cancer-related genes, anti tumor activity, cytotoxicity profile, stability, and bioavailability of these drugs. The review further presents the far known mechanisms of primary and secondary resistance to azanucleoside drugs. Finally, the review highlights the ubiquitous role of DNA hypomethylating epi-drugs as chemosensitizers and/or priming agents, and recapitulate the combinatorial cancer preventive effects of these drugs with other epigenetic agents, conventional chemo-drugs, or immunotherapies. This comprehensive review analyzes the beneficial characteristics and drawbacks of nucleosidic DNA methylation inhibitors, which will assist the pre-clinical and clinical researchers in the design of future experiments to improve the therapeutic efficacy of these drugs and circumvent the challenges in the path of successful epigenetic therapy. PMID- 29454858 TI - Expression of heat shock protein 70 and cell death kinetics after different thermal impacts on cultured retinal pigment epithelial cells. AB - Recent technologies are broadening the possibility to treat the retinal pigment epithelium (RPE) with different thermal impacts, from sublethal to lethal ranges. Thus temperature-dependent subcellular molecular responses need to be elucidated in more detail. In this study, RPE cell viability and expression of heat shock protein 70 (Hsp70) were investigated after thermal irradiation with different temperature increase using an in-vitro model. Primary porcine RPE cell cultures were irradiated with different laser power of a thulium laser (lambda = 1940 nm, beam-diameter 30 mm) for 10 s, such that the maximal temperatures at the center of the culture dish (Tmax) reach 40, 44, 47, 51 or 59 degrees C after 10-s irradiation. The temperature distribution across the culture dish shows a Gaussian decay from central position to the periphery of the dish. At 3, 24 and 48 h after irradiation cell viability was assessed with fluorescence microscopy using cell viability-indicating fluorescence dyes, followed by the determination of the threshold temperature for apoptotic change and death of RPE cells. Intracellular localization and amount of Hsp70 were investigated with immunofluorescence and western blotting, respectively. The threshold temperature (at the 10th second of irradiation: T10s) for cellular apoptosis and complete cell death showed a decrease over time after irradiation, suggesting a long-term process of thermally induced cell death. For complete cell death the threshold T10s was 52.1 +/- 0.6 degrees C, 50.1 +/- 1.4 degrees C, and 50.1 +/- 0.8 degrees C, for 3, 24 and 48 h, respectively, whereas for the apoptotic changes 48.6 +/- 1.8 degrees C, 47.2 +/- 1.3 degrees C, and 46.7 +/- 0.9 degrees C, respectively. Quantitative analysis of Hsp70 with western blotting showed a significant increase in intracellular Hsp70 at lethal irradiation with Tmax >= 51 degrees C, up to 19.6 +/- 2.3 fold after 48 h at 59 degrees C, whereas sub lethal irradiations with Tmax <= 44 degrees C led to a slight tendency of time dependent increases (up to 1.8 +/- 1.1 fold) over 48 h. Immunostainings for Hsp70 showed a circle- or ring-pattern of the Hsp70 staining during 3-48 h after irradiation, and the range of the 1st and 3rd quartiles of T10s for heat-induced Hsp70 expression over this time period was between 44.8 degrees C and 48.2 degrees C. A very strong staining of Hsp70 was observed at the border to the damaged zone, where many cells show the strong staining in the whole cytoplasmic space, while some cells in the nucleus, or some cells show the signs of cell migration and proliferation. Moreover, among the cells showing high intensity of Hsp70 staining, there are small round cells like apoptotic cells. Results suggest that RPE cell death after thermal irradiation may take time, and mostly undergoes through apoptosis, unless cells are immediately killed. Thermal irradiation induced Hsp70 expression is not only temperature-dependent, but also depends largely on the existence of neighboring cell death, suggesting the crucial role of Hsp70 in apoptosis and wound healing processes of RPE cells. The increase of Hsp70 over 24-48 h indicates its long-term roles in cell responses both after sublethal and lethal thermal laser irradiations.

AB - CD40L signaling occurs in several diseases with inflammatory components, including ocular and retinal diseases. However, it has never been evaluated as a pathogenic mechanism in age-related macular degeneration (AMD) or as an inducer of inflammasome formation in any cell type. mRNA and protein levels of CD40, IL 1beta, NALP1, NALP3, caspase-1, and caspase-5 were determined by RT-PCR, qPCR, and Western blot. CD40L receptor (CD40, alpha5beta1, and CD11b) expression was determined by Western and immunofluorescent staining. IL-1beta, IL-18, and MCP-1 secretions were determined by ELISA. NALP1 and NALP3 inflammasome formation were determined by Co-IP. Experiments were conducted on primary human retinal pigment epithelial (hRPE) cells from four different donors. Human umbilical vein endothelial (HUVEC) and monocytic leukemia (THP-1) cells demonstrated the general applicability of our findings. In hRPE cells, CD40L-induced NALP1 and NALP3 inflammasome activation, cleavage of caspase-1 and caspase-5, and IL-1beta and IL 18 secretion. Interestingly, neutralizing CD11b and alpha5beta1 antibodies, but not CD40, reduced CD40L-induced IL-1beta secretion in hRPE cells. Similarly, CD40L treatment also induced HUVEC and THP-1 cells to secret IL-1beta through CD11b and alpha5beta1. Additionally, the CD40L-induced IL-1beta secretion acted in an autocrine/paracrine manner to feed back and induce hRPE cells to secrete MCP-1. This study is the first to show that CD40L induces inflammasome activation in any cell type, including hRPE cells, and that this induction is through CD11b and alpha5beta1 cell-surface receptors. These mechanisms likely play an important role in many retinal and non-retinal diseases and provide compelling drug targets that may help reduce pro-inflammatory processes.

AB - Molecular, vesicular and organellar flows are of fundamental importance for the delivery of nutrients and essential components used in cellular functions such as motility and division. With recent advances in fluorescence/super-resolution microscopy modalities we can resolve the movements of these objects at higher spatio-temporal resolutions and with better sensitivity. Previously, spatio temporal image correlation spectroscopy has been applied to map molecular flows by correlation analysis of fluorescence fluctuations in image series. However, an underlying assumption of this approach is that the sampled time windows contain one dominant flowing component. Although this was true for most of the cases analyzed earlier, in some situations two or more different flowing populations can be present in the same spatio-temporal window. We introduce an approach, termed velocity landscape correlation (VLC), which detects and extracts multiple flow components present in a sampled image region via an extension of the correlation analysis of fluorescence intensity fluctuations. First we demonstrate theoretically how this approach works, test the performance of the method with a range of computer simulated image series with varying flow dynamics. Finally we apply VLC to study variable fluxing of STIM1 proteins on microtubules connected to the plasma membrane of Cystic Fibrosis Bronchial Epithelial (CFBE) cells. PMID- 29454859 TI - Tauroursodeoxycholic acid binds to the G-protein site on light activated rhodopsin. AB - The heterotrimeric G-protein binding site on G-protein coupled receptors remains relatively unexplored regarding its potential as a new target of therapeutic intervention or as a secondary site of action by the existing drugs. Tauroursodeoxycholic acid bears structural resemblance to several compounds that were previously identified to specifically bind to the light-activated form of the visual receptor rhodopsin and to inhibit its activation of transducin. We show that TUDCA stabilizes the active form of rhodopsin, metarhodopsin II, and does not display the detergent-like effects of common amphiphilic compounds that share the cholesterol scaffold structure, such as deoxycholic acid. Computer docking of TUDCA to the model of light-activated rhodopsin revealed that it interacts using similar mode of binding to the C-terminal domain of transducin alpha subunit. The ring regions of TUDCA made hydrophobic contacts with loop 3 region of rhodopsin, while the tail of TUDCA is exposed to solvent. The results show that TUDCA interacts specifically with rhodopsin, which may contribute to its wide-ranging effects on retina physiology and as a potential therapeutic compound for retina degenerative diseases. PMID- 29454861 TI - Methods of reconstitution to investigate membrane protein function. AB - Membrane proteins are notoriously difficult to investigate in isolation. The focus of this chapter is the key step following extraction and purification of membrane proteins; namely reconstitution. The process of reconstitution re inserts proteins into a lipid bilayer that partly resembles their native environment. This native environment is vital to the stability of membrane proteins, ensuring that they undergo vital conformational transitions and maintain optimal interaction with their substrates. Reconstitution may take many forms and these have been classified into two broad categories. Symmetric systems enable unfettered access to both sides of a bilayer. Compartment containing systems contain a lumen and are ideally suited to measurement of transport processes. The investigator is encouraged to ascertain what aspects of protein function will be undertaken and to apply the most advantageous reconstitution system or systems. It is important to note that the process of reconstitution is not subject to defined protocols and requires empirical optimisation to specific targets. PMID- 29454862 TI - Fluorescence lifetime correlation spectroscopy: Basics and applications. AB - This chapter presents a concise introduction into the method of Fluorescence Lifetime Correlation Spectroscopy (FLCS). This is an extension of Fluorescence Correlation Spectroscopy (FCS) that analyses fluorescence intensity fluctuations from small detection volumes in samples of ultra-low concentration. FCS has been widely used for investigating diffusion, conformational changes, molecular binding/unbinding equilibria, or chemical reaction kinetics, at single molecule sensitivity. In FCS, this is done by calculating intensity correlation curves for the measured intensity fluctuations. FLCS extends this idea by calculating fluorescence-lifetime specific intensity correlation curves. Thus, FLCS is the method of choice for all studies where a parameter of interest (conformational state, spatial position, molecular environmental condition) is connected with a change in the fluorescence lifetime. After presenting the theoretical and experimental basis of FLCS, the chapter gives an overview of its various applications. PMID- 29454864 TI - Inactivation of Escherichia coli and Staphylococcus aureus on contaminated perilla leaves by Dielectric Barrier Discharge (DBD) plasma treatment. AB - This study focused on sterilization methods for the reduction of microorganisms on perilla leaves by cylinder type Dielectric Barrier Discharge (DBD) plasma with underwater bubbler treatment. S. aureus and E. coli in a suspension were reduced to less than 3.4 and 0.5 log CFU/ml after the plasma treatment for 3 min, respectively. On the perilla leaves, they were also reduced to 4.8 and 1.6 log CFU/ml after the plasma treatment, respectively. The S. aureus and E. coli bacterial cell wall was damaged by the plasma treatment evident by scanning electron microscopic analysis. The observed infrared bands of the FTIR spectra demonstrated changes in protein, lipid, polysaccharide, polyphosphate group and other carbohydrate functionalities of plasma treated bacteria and untreated bacterial cell membranes. The degradation of the constituent bonds of the bacterial cell membrane by RONS generated from plasma destroys the DNA, RNA, and proteins within the cell, and may eventually cause cell death. In this study, H2O2 (13.68 MUM) and NO3 (138 MUM), which are the main factors generated by plasma, proved to have a bactericidal effect by inducing lipid peroxidation of bacterial cell membranes. In conclusion, cylinder type DBD plasma with underwater bubbler can be used as an environmentally friendly food disinfection device in cleaning processes of the food industry. PMID- 29454863 TI - Potentially Functional Variants of ATG16L2 Predict Radiation Pneumonitis and Outcomes in Patients with Non-Small Cell Lung Cancer after Definitive Radiotherapy. AB - INTRODUCTION: Autophagy not only plays an important role in the progression of cancer but is also involved in tissue inflammatory response. However, few published studies have investigated associations between functional genetic variants of autophagy-related genes and radiation pneumonitis (RP) as well as clinical outcomes in patients with NSCLC after definitive radiotherapy. METHODS: We genotyped nine potentially functional single-nucleotide polymorphisms (SNPs) in four autophagy-related genes (autophagy related 2B gene [ATG2B], autophagy related 10 gene [ATG10], autophagy related 12 gene [ATG12], and autophagy related 16 like 2 gene [ATG16L2]) in 393 North American patients with NSCLC treated by definitive radiotherapy and assessed their associations with RP, local recurrence free survival (LRFS), progression-free survival (PFS), and overall survival (OS) in multivariable Cox proportional hazard regression analyses. RESULTS: We found that patients with the ATG16L2 rs10898880 CC variant genotype had a better LRFS, PFS, and OS (adjusted hazard ratio = 0.59, 0.64, and 0.64; 95% confidence interval: 0.45-0.79, 0.48-0.84, and 0.48-0.86; p = 0.0004, 0.002, and 0.003, respectively), but a greater risk for development of severe RP (adjusted hazard ratio = 1.80, 95% confidence interval: 1.04-3.12, p = 0.037) than did patients with AA/AC genotypes. Further functional analyses suggested that the ATG16L2 rs10898880 C variant allele modulated expression of the ATG16L2 gene. CONCLUSION: This is the first report that one potentially functional SNP rs10898880 in ATG16L2 may be a predictor of RP, LRFS, PFS, and OS in patients with NSCLC after definitive radiotherapy. Additional larger, prospective studies are needed to confirm these findings. PMID- 29454865 TI - Inhibitory effects of selenium on cadmium-induced cytotoxicity in PC12 cells via regulating oxidative stress and apoptosis. AB - Purpose of this study is to investigate mechanism/s of cyto-protection by selenium (Na2SeO3; Se4+) against cadmium (CdCl2; Cd2+)-induced cytotoxicity using PC12 cells. In addition, Se (5, 10, 20 and 40 MUM) and Cd (2.5, 5 and 10 MUM) induced cytotoxicity is determined. Cytotoxicity assays and western blot analyses confirmed that Se (>=10 MUM) promotes autophagic cell death via inhibition of mTOR activation and p62 accumulation due to increase of cellular oxidative stress. On the other hand, co-presence of non-toxic Se (5 MUM) and toxic Cd (5 MUM) showed to increase cell viability, glutathione and glutathione peroxidase 1 (GPx1) levels, and to decrease DNA fragmentation and lactate dehydrogenase (LDH) activity compared to Cd-treated (5 MUM) cells alone. Furthermore, western blot analyses of cytochrome c and ERK1 indicated that Cd-induced apoptotic cell death in PC12 cells. However, the co-exposure of Se with Cd significantly decreases the release of cytochrome c into cytosol from mitochondria, and up-regulates ERK1 protein to inhibit Cd-induced apoptosis. In conclusion, Se (>=10 MUM) possess cytotoxicity in PC12 cells; however, co-presence of Se (5 MUM) with Cd (5 MUM) protects against Cd-induced apoptosis in PC12 cells due to inhibition of Cd induced oxidative stress and subsequently suppression of mitochondrial apoptosis pathway. PMID- 29454866 TI - Behavioral toxicity of sodium cyanide following oral ingestion in rats: Dose dependent onset, severity, survival, and recovery. AB - Sodium cyanide (NaCN) is a commonly and widely used industrial and laboratory chemical reagent that is highly toxic. Its availability and rapid harmful/lethal effects combine to make cyanide a potential foodborne/waterborne intentional poisoning hazard. Thus, laboratory studies are needed to understand the dose dependent progression of toxicity/lethality following ingestion of cyanide poisoned foods/liquids. We developed an oral-dosing method in which a standard pipette was used to dispense a sodium cyanide solution into the cheek, and the rat then swallowed the solution. Following poisoning (4-128 mg/kg), overt toxic signs were recorded and survival was evaluated periodically up to 30 hours thereafter. Toxic signs for NaCN doses higher than 16 mg/kg progressed quickly from head burial and mastication, to lethargy, convulsions, gasping/respiratory distress, and death. In a follow-on study, trained operant-behavioral performance was assessed immediately following cyanide exposure (4-64 mg/kg) continuously for 5 h and again the following day. Onset of behavioral intoxication (i.e., behavioral suppression) occurred more rapidly and lasted longer as the NaCN dose increased. This oral-consumption method with concomitant operantbehavioral assessment allowed for accurate dosing and quantification of intoxication onset, severity, and recovery, and will also be valuable in characterizing similar outcomes following varying medical countermeasure drugs and doses. PMID- 29454867 TI - Acellular filtrate of a microbial-based cleaning product potentiates house dust mite allergic lung inflammation. AB - Microbial-based cleaning products (MBCPs) contain bacteria and chemical constituents. They are used in consumer applications such as odor reduction, unclogging drains, and surface cleaning. To determine the capacity of a model MBCP to contribute to acute allergic lung inflammation, a two-week repeated exposure regimen was used. Mice were exposed by endotracheal instillation to saline alone, MBCP alone, house dust mites (HDM) alone, or sequentially (i.e., MBCP followed by HDM, HDM followed by MBCP, or HDM + MBCP followed by HDM). Both whole MBCP and acellular MBCP filtrate were investigated, and showed minimal differences in the endpoints examined. HDM exposure caused pulmonary perivascular inflammation, bronchiolar mucous cell metaplasia, elevated bronchoalveolar lavage fluid (BALF) eosinophils, and HDM-specific IgG1. For MBCP, notable changes were associated with sequential exposures. MBCP/HDM caused elevated TH2 cytokines in BALF, and elevated neutrophils, eosinophils and IL-5 in peripheral blood. Co administration of MBCP and HDM followed by HDM resulted in elevated blood and BALF eosinophils and HDM-specific IgE and IgG1. These results demonstrated that acellular MBCP filtrate, and not bacteria within MBCPs, potentiated the acute allergic inflammation to HDM. This methodology could be extended to investigate chronic allergic inflammation and inflammatory potential of other MBCPs and biotechnology products with complex compositions. PMID- 29454868 TI - Halophytic herbs of the Mediterranean basin: An alternative approach to health. AB - Wild native species are usually grown under severe and stressful conditions, while a special category includes halophytic species that are tolerant to high salinity levels. Native halophytes are valuable sources of bioactive molecules whose content is higher in saline than normal conditions, since the adaptation to salinity mechanisms involve apart from changes in physiological functions the biosynthesis of protectant molecules. These compounds include secondary metabolites with several beneficial health effects which have been known since ancient times and used for medicinal purposes. Recent trends in pharmaceutical industry suggest the use of natural compounds as alternative to synthetic ones, with native herbs being strong candidates for this purpose due to their increased and variable content in health promoting compounds. In this review, an introductory section about the importance of native herbs and halophyte species for traditional and modern medicine will be presented. A list of the most important halophytes of the Mediterranean basin will follow, with special focus on their chemical composition and their reported by clinical and ethnopharmacological studies health effects. The review concludes by suggesting future requirements and perspectives for further exploitation of these valuable species within the context of sustainability and climate change. PMID- 29454869 TI - The intrapartum and perinatal risks of sleep-disordered breathing in pregnancy: a systematic review and metaanalysis. AB - OBJECTIVE DATA: Sleep-disordered breathing is an increasingly common condition in nonobstetric populations and is associated with significant morbidity. The incidence of sleep-disordered breathing in pregnancy is unknown, and it is likely that many cases go undiagnosed. STUDY: A systematic review and metaanalysis was undertaken to determine whether pregnant women who receive a diagnosis of sleep disordered breathing are more likely to have adverse intrapartum and perinatal outcomes compared with control subjects. STUDY APPRAISAL AND SYNTHESIS METHODS: PubMed, Embase, and Cinahl databases were searched for full-text publications in English of sleep-disordered breathing and human pregnancy up to June 2017. Only studies that reported on sleep-disordered breathing in relation to gestational age or birthweight at delivery, preterm birth, mode of delivery, cord pH, Apgar score, nursery admission, stillbirth or perinatal death, meconium at delivery, or wound complications were included. RESULTS: A total of 1576 results were identified; 33 studies met inclusion criteria. Women with sleep-disordered breathing were older (mean difference, 1.66; 95% confidence interval, 1.04-2.28) and had a higher body mass index (mean difference, 3.31; 95% confidence interval, 2.30-4.32) than those who did not. Maternal sleep-disordered breathing was associated significantly with preterm birth (<37 weeks gestation; odds ratio, 1.86; 95% confidence interval, 1.50-2.31) and low birthweight (<2500 g; odds ratio, 1.67; 95% confidence interval, 1.00-2.78). These women were also less likely to have a vaginal delivery (odds ratio, 0.61; 95% confidence interval, 0.48-0.78) and to be at a higher risk of having an assisted vaginal delivery (odds ratio, 1.88; 95% confidence interval, 1.10-3.21) or a cesarean delivery (odds ratio, 1.81; 95% confidence interval, 1.55-2.11). The risk of both elective (odds ratio, 1.38; 95% confidence interval, 1.09 - 1.76) and emergency cesarean (odds ratio, 2.52; 95% confidence interval, 1.20-5.29) was increased. In addition, women with sleep-disordered breathing were at a higher risk of having an infant with a 5-minute Apgar score <7 (odds ratio, 2.14; 95% confidence interval, 1.24-3.71), stillbirth or perinatal death (odds ratio, 2.02; 95% confidence interval, 1.25-3.28), and neonatal nursery admission (odds ratio, 1.90; 95% confidence interval, 1.38-2.61). CONCLUSION: Maternal sleep-disordered breathing is associated with increased risks of adverse intrapartum and perinatal outcomes. PMID- 29454870 TI - Levator ani defect severity and its association with enlarged hiatus size, levator bowl depth, and prolapse size. PMID- 29454871 TI - Maternal and neonatal outcomes after bariatric surgery; a systematic review and meta-analysis: do the benefits outweigh the risks? AB - OBJECTIVE DATA: Obesity during pregnancy is associated with a number of adverse obstetric outcomes that include gestational diabetes mellitus, macrosomia, and preeclampsia. Increasing evidence shows that bariatric surgery may decrease the risk of these outcomes. Our aim was to evaluate the benefits and risks of bariatric surgery in obese women according to obstetric outcomes. STUDY: We performed a systematic literature search using MEDLINE, Embase, Cochrane, Web of Science, and PubMed from inception up to December 12, 2016. Studies were included if they evaluated patients who underwent bariatric surgery, reported subsequent pregnancy outcomes, and compared these outcomes with a control group. STUDY APPRAISAL AND SYNTHESIS METHODS: Two reviewers extracted study outcomes independently, and risk of bias was assessed with the use of the Newcastle-Ottawa Quality Assessment Scale. Pooled odds ratios for each outcome were estimated with the Dersimonian and Laird random effects model. RESULTS: After a review of 2616 abstracts, 20 cohort studies and approximately 2.8 million subjects (8364 of whom had bariatric surgery) were included in the metaanalysis. In our primary analysis, patients who underwent bariatric surgery showed reduced rates of gestational diabetes mellitus (odds ratio, 0.20; 95% confidence interval, 0.11 0.37, number needed to benefit, 5), large-for-gestational-age infants (odds ratio, 0.31; 95% confidence interval, 0.17-0.59; number needed to benefit, 6), gestational hypertension (odds ratio, 0.38; 95% confidence interval, 0.19-0.76; number needed to benefit, 11), all hypertensive disorders (odds ratio, 0.38; 95% confidence interval, 0.27-0.53; number needed to benefit, 8), postpartum hemorrhage (odds ratio, 0.32; 95% confidence interval, 0.08-1.37; number needed to benefit, 21), and caesarean delivery rates (odds ratio, 0.50; 95% confidence interval, 0.38-0.67; number needed to benefit, 9); however, group of patients showed an increase in small-for-gestational-age infants (odds ratio, 2.16; 95% confidence interval, 1.34-3.48; number needed to harm, 21), intrauterine growth restriction (odds ratio, 2.16; 95% confidence interval, 1.34-3.48; number needed to harm, 66), and preterm deliveries (odds ratio, 1.35; 95% confidence interval, 1.02-1.79; number needed to harm, 35) when compared with control subjects who were matched for presurgery body mass index. There were no differences in rates of preeclampsia, neonatal intensive care unit admissions, stillbirths, malformations, and neonatal death. Malabsorptive surgeries resulted in a greater increase in small-for-gestational-age infants (P=.0466) and a greater decrease in large-for-gestational-age infants (P=<.0001) compared with restrictive surgeries. There were no differences in outcomes when we used administrative databases vs clinical charts. CONCLUSION: Although bariatric surgery is associated with a reduction in the risk of several adverse obstetric outcomes, there is a potential for an increased risk of other important outcomes that should be considered when bariatric surgery is discussed with reproductive-age women. PMID- 29454872 TI - Simultaneous formation of 3-deoxy-d-threo-hexo-2-ulose and 3-deoxy-d-erythro-hexo 2-ulose during the degradation of d-glucose derived Amadori rearrangement products: Mechanistic considerations. AB - Analyzing classical model reaction systems of Amadori rearrangement products (ARP) it became apparent that the formation of 3-deoxy-d-threo-hexo-2-ulose (3 deoxygalactosone, 3-DGal) during the degradation of ARPs is highly dependent on pH and the amino acid residue of the respective ARP. Based on a detailed analysis of the NMR chemical shifts of the sugar moieties of different ARPs, it could be derived that the formation of 3-DGal is sensitive to the stability of a co operative hydrogen bond network which involves HO-C3, the deprotonated carboxyl functionality and the protonated amino nitrogen of the amino acid substituent. Participating in this bond network, HO-C3 is partially protonated which facilitates the elimination of water at C3. Based on that, a new mechanism of 3 deoxyglycosone formation is proposed. PMID- 29454873 TI - Strategies for implementing a multiple patient simulation scenario. AB - Nursing students often care for one or two patients during hospital clinical experiences, while under the supervision of a nurse educator. In this setting, students have limited opportunities to make clinical judgments, prioritize, and delegate while caring for multiple patients. Research supports the need for students to have increased experiences in caring for multiple patients. The aim of this paper is to examine the effectiveness of a multiple patient simulated clinical experience (SCE) on senior students' perception of their readiness to transition to practice. There were 214 senior nursing student participants in this mixed methods embedded design study. Following a multiple patient SCE all participants completed a self-report survey designed to measure essential competencies for transition to practice. Qualitative data in the form of written comments were also collected. Essential competencies for transition to practice were defined as decision making skills, interprofessional communication, and level of preparedness. Quantitative and qualitative data indicated that students perceived increased levels of confidence in their readiness to transition to practice following the multiple patient SCE. The study revealed an innovative teaching-learning strategy that can assist educators with preparing nursing students to care for multiple complex patients. PMID- 29454874 TI - Stressors for Spanish nursing students in clinical practice. AB - BACKGROUND: Clinical practice is critical for nursing students to acquire the knowledge and skills needed to properly develop professionally. The presence of stress in clinical practice may negatively affect their training. OBJECTIVES: To understand the extent to which clinical practice can be stressful for nursing students at a Spanish university and to determine the main stressors associated with the practice. DESIGN: Cross-sectional, descriptive, and observational study conducted in 2016 at the two nursing colleges of the University of Oviedo, located in Oviedo and Gijon in the Principality of Asturias, Spain. METHODS: A total of 450 nursing students at a Spanish university served as participants in this study from January to April 2016. A data collection sheet was developed to track different sociodemographic variables, and was distributed together with the KEZKAK questionnaire, a validated scale adapted to Spanish nursing students. It is composed of 41 items using a 4-point Likert scale, rating how much the described situation worries them from 0 ("Not at all") to 3 ("A lot"). RESULTS: Students were most concerned about issues relating to causing harm to patients and lack of competence. Women found clinical practice to be more stressful than men did, both in general terms (p < 0.001) and with respect to all individual factors included in the questionnaire. In addition, there were associations between the "lack of competence" factor and having a job simultaneously (p = 0.011), the "contact with suffering" factor and the school year (p = 0.018), and the "being harmed by the relationship with patients" factor and the age group (p = 0.013). CONCLUSIONS: Nursing students, particularly women, see clinical practice as "rather stressful", with the main stressors being those related to causing harm to patients. PMID- 29454875 TI - Does the level of emotional intelligence affect the degree of success in nursing studies? AB - BACKGROUND: Emotional intelligence (EI) reflects the general capacity to comprehend emotions (in ourselves and in others), to regulate emotions, and to cope effectively with emotional situations. The study program in nursing is varied, and includes theoretical and practical aspects, but teaching EI is not part of the core curriculum. We argue that teaching EI should not only be included in the curriculum, but that EI tests should be included in the admissions process. OBJECTIVE: This study reviews the relationship between EI level and the degree of success in nursing studies, and its importance. PARTICIPANTS: A convenience sample of 110 academic nursing students was examined. METHODS: Three data collection methods were employed: 1) A socio-demographic questionnaire; 2) Schutte Self-Report Inventory (SSRI); 3) Psychometric scores and grade transcripts. RESULTS: A positive correlation between the level of EI and the degree of success in nursing studies among nursing students was found. EI levels improved during the second year of learning. Among nursing students, the annual average grade was related to emotional intelligence rather than psychometric scores at the time of admission. CONCLUSION: There is a need to increase the importance of EI in the terms of nursing student's admission and basic nursing curriculums. PMID- 29454876 TI - The development and psychometric validation of an instrument to evaluate nurses' attitudes towards communication with the patient (ACO). AB - BACKGROUND: Patient communication is a key skill for nurses involved in clinical care. Its measurement is a complex phenomenon that can be addressed through attitude evaluation. OBJECTIVES: To develop and psychometrically test a measure of nurses' attitudes towards communication with patients (ACO), to study the relationship between these dimensions, and to analyse nursing attitudes. DESIGN: To develop and psychometrically test the ACO questionnaire. SETTINGS: All hospitals in the province of Valencia were invited by e-mail to distribute the ACO instrument. Ten hospitals took part in the study. PARTICIPANTS: The study population was composed of a convenience sample of 400 hospital nurses on general or special services. The inclusion criteria were nurses at the selected centres who had previously provided an informed consent to participate. METHODS: A literature review and expert consultation (N = 10) was used to develop the content of the questionnaire. The 62-item version of the instrument was applied to a convenience sample of 400 nurses between May 2015 and March 2016. Factor structure was evaluated with exploratory and confirmatory factor analysis (EFA, CFA), and reliability was evaluated with Cronbach's alpha, composite reliability (CR), and average variance extracted (AVE). RESULTS: The final instrument (ACO), composed of 25 items grouped into three attitude dimensions (cognitive, affective and behavioural), had good psychometric properties. In the study sample, nurses had a favourable attitude towards communication. The cognitive and affective dimensions of the ACO should be able to predict the behaviour dimension. CONCLUSION: The ACO is useful for evaluating current clinical practices, identifying educational needs and assessing the effectiveness of communication training or other interventions intended to improve communication. PMID- 29454877 TI - Egyptian and Jordanian nurse educators' perception of barriers preventing the implementation of evidence-based practice: A cross-sectional study. AB - BACKGROUND: Studies discussing nurse educators' attitudes, knowledge/skills, practicing of evidence-based practice (EBP) and barriers encountered towards implementation is somewhat limited. OBJECTIVE: The study aimed to identify the attitudes, perceived knowledge/skills, and implementation of evidence-based as perceived by nurse educators, in Egyptian and Jordanian universities, and to assess factors preventing them from adopting it in nursing program. DESIGN/SETTING/RESPONDENTS/METHODS: A cross-sectional design was conducted including two groups from Egypt and Jordan. Two questionnaires: (i) The Evidence Based Practice Questionnaire (EBPQ) and (ii) The Developing Evidence-Based Practice Questionnaire (DEBPQ) and a demographic data sheet were used. Data were analyzed using SPSS version 20 and descriptive and inferential statistics tabulated. RESULTS: Majority of the respondents (85.5%) were females, <40 years old (62.1%), and from medical-surgical nursing departments (49.2%). The mean score of EBPQ was 4.96 +/- standard deviation 0.91. Frequency of practicing EBP and attitudes toward EBP scores were similar between nurse educators in both countries (p > 0.05). However, the Jordanian staff had a remarkably higher perceived knowledge/skills of EBP than their Egyptian counterparts (Mean Rank = 79.98 & 57.63 respectively, at p = 0.004). There was a statistically significant positive, moderate correlation between attitudes, knowledge/skills and frequency of practicing EBP among nurse educators in both countries. The highest correlation observed for attitudes and frequency of practicing EBP was among Jordanian staff (r = 0.707, p < 0.000). Egyptian nurse educators had significantly higher perceived barriers to finding and reviewing evidence than their Jordanian counterparts (p = 0.000). However, both groups had similar perceived barriers related to changing practice and support from colleagues. CONCLUSIONS: Egyptian and Jordanian nurse educators, equally, hold positive attitudes toward adopting EBP. However, they encounter many barriers to implement it.

PMID- 29454879 TI - Application of genetically encoded redox biosensors to measure dynamic changes in the glutathione, bacillithiol and mycothiol redox potentials in pathogenic bacteria. AB - Gram-negative bacteria utilize glutathione (GSH) as their major LMW thiol. However, most Gram-positive bacteria do not encode enzymes for GSH biosynthesis and produce instead alternative LMW thiols, such as bacillithiol (BSH) and mycothiol (MSH). BSH is utilized by Firmicutes and MSH is the major LMW thiol of Actinomycetes. LMW thiols are required to maintain the reduced state of the cytoplasm, but are also involved in virulence mechanisms in human pathogens, such as Staphylococcus aureus, Mycobacterium tuberculosis, Streptococcus pneumoniae, Salmonella enterica subsp. Typhimurium and Listeria monocytogenes. Infection conditions often cause perturbations of the intrabacterial redox balance in pathogens, which is further affected under antibiotics treatments. During the last years, novel glutaredoxin-fused roGFP2 biosensors have been engineered in many eukaryotic organisms, including parasites, yeast, plants and human cells for dynamic live-imaging of the GSH redox potential in different compartments. Likewise bacterial roGFP2-based biosensors are now available to measure the dynamic changes in the GSH, BSH and MSH redox potentials in model and pathogenic Gram-negative and Gram-positive bacteria. In this review, we present an overview of novel functions of the bacterial LMW thiols GSH, MSH and BSH in pathogenic bacteria in virulence regulation. Moreover, recent results about the application of genetically encoded redox biosensors are summarized to study the mechanisms of host-pathogen interactions, persistence and antibiotics resistance. In particularly, we highlight recent biosensor results on the redox changes in the intracellular food-borne pathogen Salmonella Typhimurium as well as in the Gram positive pathogens S. aureus and M. tuberculosis during infection conditions and under antibiotics treatments. These studies established a link between ROS and antibiotics resistance with the intracellular LMW thiol-redox potential. Future applications should be directed to compare the redox potentials among different clinical isolates of these pathogens in relation to their antibiotics resistance and to screen for new ROS-producing drugs as promising strategy to combat antimicrobial resistance.

AB - In the last two decades, there has been a significant advance in understanding the biochemistry of peroxynitrite, an endogenously-produced oxidant and nucleophile. Its relevance as a mediator in several pathologic states and the aging process together with its transient character and low steady-state concentration, motivated the development of a variety of techniques for its unambiguous detection and estimation. Among these, fluorescence and chemiluminescence approaches have represented important tools with enhanced sensitivity but usual limited specificity. In this review, we analyze selected examples of molecular probes that permit the detection of peroxynitrite by fluorescence and chemiluminescence, disclosing their mechanism of reaction with either peroxynitrite or peroxynitrite-derived radicals. Indeed, probes have been divided into 1) redox probes that yield products by a free radical mechanism, and 2) electrophilic probes that evolve to products secondary to the nucleophilic attack by peroxynitrite. Overall, boronate-based compounds are emerging as preferred probes for the sensitive and specific detection and quantitation. Moreover, novel strategies involving genetically-modified fluorescent proteins with the incorporation of unnatural amino acids have been recently described as peroxynitrite sensors. This review analyzes the most commonly used fluorescence and chemiluminescence approaches for peroxynitrite detection and provides some guidelines for appropriate experimental design and data interpretation, including how to estimate peroxynitrite formation rates in cells.

AB - Diminished cognitive and mood function are among the most conspicuous symptoms of Gulf War Illness (GWI). Our previous studies in a rat model of GWI have demonstrated that persistent cognitive and mood impairments are associated with substantially declined neurogenesis, chronic low-grade inflammation, increased oxidative stress and mitochondrial dysfunction in the hippocampus. We tested the efficacy of curcumin (CUR) to maintain better cognitive and mood function in a rat model of GWI because of its neurogenic, antiinflammatory, antioxidant, and memory and mood enhancing properties. Male rats were exposed daily to low doses of GWI-related chemicals, pyridostigmine bromide, N,N-diethyl-m-toluamide (DEET) and permethrin, and 5-minutes of restraint stress for 28 days. Animals were next randomly assigned to two groups, which received daily CUR or vehicle treatment for 30 days. Animals also received 5'-bromodeoxyuridine during the last seven days of treatment for analysis of neurogenesis. Behavioral studies through object location, novel object recognition and novelty suppressed feeding tests performed sixty days after treatment revealed better cognitive and mood function in CUR treated GWI rats. These rats also displayed enhanced neurogenesis and diminished inflammation typified by reduced astrocyte hypertrophy and activated microglia in the hippocampus. Additional studies showed that CUR treatment to GWI rats enhanced the expression of antioxidant genes and normalized the expression of multiple genes related to mitochondrial respiration. Thus, CUR therapy is efficacious for maintaining better memory and mood function in a model of GWI. Enhanced neurogenesis, restrained inflammation and oxidative stress with normalized mitochondrial respiration may underlie better memory and mood function mediated by CUR treatment.

AB - In the past years, there has been a mounting trend toward the addition of sympathomimetic stimulants in sports and weight loss supplements sold in the US and claimed to be from natural constituents. The latest among those pharmaceutical stimulants is 1,5-dimethylhexylamine (1,5-DMHA or octodrine), an ingredient in newly introduced sports and weight loss supplements with its 'natural' origin being cited from Aconitum or Kigelia plants. In order to validate the natural existence of 1,5-DMHA, two GC/MS methods were developed. One method involved using thick film megabore capillary columns to analyze the underivatized 1,5-DMHA. The second method was to determine enantiomeric distribution of 1,5-DMHA. Fifteen Aconitum or Kigelia plant samples originating from various locations were analyzed, and none of them contained 1,5-DMHA within the limit of detection (25 ng/mL) of the method. In contrast, although 1,5-DMHA was listed on the labels or website for all the 13 dietary supplements, only four products were found to contain this compound, with the highest quantity being reported as 112 mg per serving size. This is equivalent to more than three times the highest pharmaceutical dose established in Europe. The enantiomeric ratios of 1,5-DMHA in these products were determined to be between 0.9-1.0 (expressed as peak area ratio of one enantiomer over another), suggesting racemic nature. Interestingly, two byproducts from 1,5-DMHA synthesis were identified in commercial supplements containing 1,5-DMHA, indicating that 1,5-DMHA indeed originated from a poor quality source. Overall, the significant amount of 1,5 DMHA observed in the supplements, the enantiomeric distribution and the presence of the synthetic byproducts all suggested the synthetic origin of 1,5-DMHA in the commercial products. PMID- 29454883 TI - Obesity or diet? Levels and determinants of phthalate body burden - A case study on Portuguese children. AB - In this study we analyzed one of the most comprehensive sets of 21 urinary phthalate metabolites representing exposure to 11 parent phthalates (DEP, DMP, DiBP, DnBP, BBzP, DEHP, DiNP, DiDP, DCHP, DnPeP, DnOP) in first morning urine samples of 112 Portuguese children (4-18 years) sampled in 2014/15. The study population consisted of two groups: group 1 with normal weight/underweight children (N = 43) following their regular diet and group 2 with obese/overweight children (N = 69) following a healthy diet (with nutritional counselling). Most of the metabolites were above the limits quantification (81-100%) except for MCHP, MnPEP and MnOP. Metabolite levels were generally comparable to other recent child and general populations sampled worldwide, confirming the steady decline in exposures to most phthalates. Compared to Portuguese children sampled in 2011/2012, median urinary metabolite levels decreased by approximately 50% for DEHP, DnBP, DiBP and BBzP. Risk assessments for individual phthalates and the sum of the anti-androgenic phthalates did not indicate to attributable health risks, also at the upper percentiles of exposure. In the healthy diet group the median concentration of the DEHP metabolites was significant lower, while all phthalate metabolites except MEP tended to be lower compared to the regular diet group. Multiple log-linear regression analyses revealed significantly lower daily intakes (DIs) for all phthalates in the healthy diet group compared to the regular diet group (geometric mean ratios (gMR) between 0.510-0.618; p <= 0.05), except for DEP (gMR: 0.811; p = 0.273). The same analyses with the continuous variable body mass index instead of the diet groups also showed effects on the DIs (gMRs between 0.926-0.951; p <= 0.05), however much smaller than the effects of the diet. The results indicate that obese children following a healthy diet composed of fresh and less packaged/processed food can considerably reduce their intake for most phthalates and can have lower phthalate intakes than regular weight/regular diet children. PMID- 29454885 TI - Attending to identity cues reduces the own-age but not the own-race recognition advantage. AB - Adults' ability to recognize individual faces is shaped by experience. Young adults recognize own-age and own-race faces more accurately than other-age and other-race faces. The own-age and own-race biases have been attributed to differential perceptual experience and to differences in how in-group vs. out group faces are processed, with in-group faces being processed at the individual level and out-group faces being processed at the categorical level. To examine this social categorization hypothesis, young adults studied young and older faces in Experiment 1 and own- and other-race faces in Experiment 2. During the learning phase the identity-matching group viewed faces in pairs and completed a same/different task designed to enhance attention to individuating cues; the passive-viewing group memorized faces presented individually. After the learning phase, all participants completed an identical old/new recognition task. Both passive-viewing groups showed the expected recognition bias, but divergent patterns were observed in the identity-matching groups. Whereas the identity matching task eliminated the own-age bias, it neither eliminated nor reduced the own-race bias. Collectively, these results suggest that categorization individuation processes do not play the same role in explaining the two recognition biases. PMID- 29454884 TI - Illusory edges comingle with real edges in the neural representation of objects. AB - The visual system must transform a point-by-point biological representation from the photoreceptors into neural representations of separate objects. Even a uniform circular patch of light that slowly modulates in luminance can be segmented into separate central and surrounding areas merely by introducing black lines to outline a central square. The black lines cause brightness induction in the center even though the light inside and outside the square is always identical, as predicted by spatial antagonism between the square central area and its surround. Importantly, illusory Kanizsa lines forming the square are as effective for this brightness induction as real black lines, suggesting a 'form cue invariant' cortical neural representation that does not distinguish between a central region set off by real or illusory edges. An open question is whether separate subsystems generate objects defined by real versus illusory edges, each providing the same form-cue invariant neural representation of an object, or whether form-cue invariance extends to integrating component pieces that together define an object. Experiments here show object segmentation when subparts of a square are defined by a mixture of real and illusory edges. Subjects adjusted the Michelson contrast of a separate patch to match the perceived modulation depth within the central region of a circular field that slowly oscillated in luminance. A closed, four-sided figure, no matter how constructed, reduced the perceived modulation depth within the central region. This shows that both real and illusory subparts can be integrated to segment center from surround. It supports a strong version of form-cue invariance in which neural mechanisms responsible for object segmentation are impartial to the piecemeal cues that are integrated to define an object. PMID- 29454886 TI - Development of neuropathology following soman poisoning and medical countermeasures. AB - Nerve agent-induced seizures can cause varying degrees of neuropathology depending on level of poisoning and duration of seizing. The intention of this review was to validate a novel approach for establishing effective treatment regimens against soman poisoning. Identification of seizure controlling sites in the forebrain of rats poisoned by soman was made by means of lesions, and the anticonvulsive properties of a number of relevant drugs were tested by microinfusions into the identified areas. By using these procedures, procyclidine emerged as the most potent drug. Its potency was confirmed in systemic studies and is further enhanced when combined with levetiracetam. Acute treatment with a combination of HI-6, levetiracetam and procyclidine (procyclidine regimen) can effectively manage supralethal poisoning by any of the classical nerve agents. Extended treatment with the procyclidine regimen is able to terminate residual "silent", local epileptiform activity in the severely poisoned rats. Evident advantages are seen when the same regimen exerts both powerful anticonvulsant and neuroprotectant efficacies. According to the results presented, the new strategy for establishing therapies against soman-induced seizures appears to be valid. PMID- 29454887 TI - Metabolomic analysis uncovered an association of serum phospholipid levels with estrogen-induced mammary tumors in female ACI/Seg rats. AB - Estrogen is reported to be involved in mammary tumorigenesis. To unveil metabolic signatures for estrogen-induced mammary tumorigenesis, we carried out serum metabolomic analysis in an estrogen-induced mammary tumor model, female August Copenhagen-Irish/Segaloff (ACI/Seg) rats, using liquid chromatography-mass spectrometry. In contrast to the control group, all rats with an implanted 17beta estradiol (E2) pellet developed mammary tumors during this experiment. E2 treatment significantly suppressed body weight gain. But no significant differences in food consumption were observed between the two groups, suggesting that metabolic alteration depended on E2 treatment. Serum metabolomic analysis detected 116 features that were statistically different (p < 0.01) between the groups. Quantitation analysis revealed that several phospholipids such as phosphatidylcholines and lysophosphatidylcholines (LPCs) were identified as significantly different metabolites. E2-treated rat serum stimulated the proliferation of human breast cancer MDA-MB-231 cells. In addition, the proliferation effect was diminished by pretreating cells with either autotaxin inhibitor or antagonist for lysophosphatidic acid receptor whose ligands are metabolites of LPCs via autotaxin-mediated hydrolysis. In summary, our results suggest that not only are phospholipids potential biomarkers for mammary tumors but importantly, LPCs themselves could be associated with E2-induced mammary tumorigenesis in female ACI/Seg rats. PMID- 29454888 TI - Bioequivalence decision for nanoparticular iron complex drugs for parenteral administration based on their disposition. AB - Although parenteral iron products have been established to medicinal use decades before, their structure and pharmacokinetic properties are not fully characterized yet. With its' second reflection paper on intravenous iron-based nano-colloidal products (EMA/CHMP/SWP/620008/2012) the European Medicine Agency provided an extensive catalogue of methods for quality, non-clinical and pharmacokinetic studies for the comparison of nano-sized iron products to an originator (EMA, 2015). For iron distribution studies, the reflection paper assumed the use of rodents. In our tests, we used a turkey fetus model to investigate time dependent tissue concentrations in pharmacological and toxicological relevant tissues liver, heart and kidney. We found turkey embryos to be a suitable alternative to rodents with high discriminatory sensitivity. Clear differences were found between equimolar doses of iron products with hydroxyethyl amylopectin, sucrose, dextrane and carboxymaltose shell. A linear dose dependency for the tissue accumulation was also demonstrated. PMID- 29454889 TI - Evolution of sexual systems and growth habit in Mussaenda (Rubiaceae): Insights into the evolutionary pathways of dioecy. AB - Dioecy is a rare sexual system that is thought to represent an "evolutionary dead end". While many studies have addressed the evolution of dioecy and/or its relationship with the evolution of the woody habit, few have explored the relationship between dioecy and climbing habit, and their effects on diversification rates. Here, we study the evolution of sexual systems and growth habit in Mussaenda (Rubiaceae) using a robust phylogeny of the genus based on eight plastid regions and a broad sampling of taxa (92 of the 132 species were sampled). A time-calibrated tree was constructed to estimate diversification rates in different clades and its correlates with focal characters. More specifically, we assess evolutionary correlations between dioecy and climbing habit and their respective influences on diversification rates. Ancestral character state reconstructions revealed that distyly is the most likely ancestral state in Mussaenda. Distyly has subsequently given rise to dioecy, short-styled floral monomorphism, and long-styled floral monomorphism. Dioecy has evolved independently at least four times from distyly, and has reversed to homostylous hermaphroditism at least twice, which does not support the "evolutionary dead end" hypothesis. A significant correlation between the evolution of dioecy and climbing growth form was found in Mussaenda. It is possible that a strong association between high net diversification rates and dioecy may exist in Mussaenda, but no association was found with climbing habit. PMID- 29454890 TI - Compositional accuracy of atom probe tomography measurements in GaN: Impact of experimental parameters and multiple evaporation events. AB - A systematic study of the biases occurring in the measurement of the composition of GaN by Atom Probe Tomography was carried out, in which the role of surface electric field and laser pulse intensity has been investigated. Our data confirm that the electric field is the main factor influencing the measured composition, which exhibits a deficiency of N at low field and a deficiency of Ga at high field. The deficiency of Ga at high field is interpreted in terms of preferential evaporation of Ga. The detailed analysis of multiple evaporation events reveals that the measured composition is not affected by pile-up phenomena occurring in detection system. The analysis of correlation histograms yields the signature of the production of neutral N2 due to the dissociation of GaN32+ ions. However, the amount of N2 neutral molecules that can be detected cannot account for the N deficiency found at low field. Therefore, we propose that further mechanisms of neutral N evaporation could be represented by dissociation reactions such as GaN+ > Ga++ N and GaN2+-> Ga2++ N. PMID- 29454891 TI - A new procedure for processing extracted teeth for immediate grafting in post extraction sockets. An experimental study in American Fox Hound dogs. AB - OBJECTIVES: To investigate freshly extracted dental particulate used to graft post-extraction sockets in dogs, comparing new bone formation at experimental and control sites. MATERIALS AND METHODS: Bilateral premolars P2, P3, P4 and first mandibular molars were extracted atraumatically from six American Fox Hound dogs. The teeth were ground immediately using a 'Smart Dentin Grinder'. The dentin particulate was sieved to ensure a grain size of 300-1200MUm and immersed in an alcohol cleanser to dissolve organic debris and bacteria, followed by washing in sterile saline buffer solution. The animals were divided into two groups randomly: group 'A' (control) samples were left to heal without any extraction socket grafting procedure; group 'B' (experimental) sockets were filled with the autogenous dentin particulate graft. The rate of tissue healing and the quantity of bone formation were evaluated using histological and histomorphometric analyses at 60 and 90 days post-grafting. The type of bone generated was categorized as woven (immature bone) or lamellar bone (mature bone). RESULTS: Substantially more bone formation was found in Group B (experimental) than Group A (control) at 60 and 90 days (p<0.05). Less immature bone was identified in the dentin grafted group (25.7%) than the control group (55.9%) [corrected]. Similar differences were also observed at 90 days post grafting. CONCLUSION: Autogenous dentin particulate grafted immediately after extractions may be considered a useful biomaterial for socket preservation, protecting both buccal and lingual plates, generating large amounts of new woven bone formation after 60 days, and small amounts of lamellar bone after 90 days healing. PMID- 29454892 TI - Fexaramine as an entry blocker for feline caliciviruses. AB - Feline calicivirus (FCV) is a small non-enveloped virus containing a single stranded, positive-sense RNA genome of approximately 7.7 kb. FCV is a highly infectious pathogen of cats and typically causes moderate, self-limiting acute oral and upper respiratory tract diseases or chronic oral diseases. In addition, in recent years, virulent, systemic FCV (vs-FCV) strains causing severe systemic diseases with a high mortality rate of up to 67% have been reported in cats. Although FCV vaccines are commercially available, their efficacy is limited due to antigenic diversity of FCV strains and short duration of immunity. In this study, we identified fexaramine as a potent inhibitor of FCV including vs-FCV strains in cell culture and demonstrated that fexaramine is a entry blocker for FCV by using various experiments including time-of-addition studies, generation of resistant viruses in cell culture and the reverse genetics system. A fexaramine resistant FCV mutant has a single amino acid change in the P2 domain of VP1 (the major capsid), and the importance of this mutation for conferring resistance was confirmed using the reverse genetics system. A comparative analysis of viral resistance was also performed using a peptidyl inhibitor (NPI52) targeting FCV 3C-like protease. Finally, the effects of combination treatment of fexaramine and NPI52 against FCV replication and emergence of resistant viruses were investigated in cell culture.

AB - Clonal propagation plays a critical integral role in the growth and success of a global multi-billion dollar horticulture industry through a constant supply of healthy stock plants. The supply chain depends on continuously improving the micropropagation process, thus, understanding the physiology of in vitro plants remains a core component. We evaluated the influence of exogenously applied cytokinins (CKs, N6-benzyladenine = BA, isopentenyladenine = iP, meta-topolin = mT, 6-(3-hydroxybenzylamino)-9-(tetrahydropyran-2-yl)purine = mTTHP) in Murashige and Skoog (MS)-supplemented media on organogenic response and accumulation of endogenous CK and indole-3-acetic acid (IAA) metabolites. The highest shoot proliferation (30 shoots/explant) was obtained with 20 MUM mT treatment. However, the best quality regenerants were produced in 10 MUM mT treatment. Rooting of Amelanchier alnifolia in vitro plantlets was observed at the lowest CK concentrations, with the highest root proliferation (3 roots/explant) in 1 MUM mTTHP regenerants. Similar to the organogenic response, high levels of endogenous bioactive CK metabolites (free bases, ribosides, and nucleotides) were detected in mT and mTTHP-derived regenerants. The level of O-glucosides was also comparatively high in these cultures. All CK-treated plants had high levels of endogenous free IAA compared to the control. This may suggest an influence of CKs on biosynthesis of IAA.

PMID- 29454895 TI - Ensemble coding of face identity is present but weaker in congenital prosopagnosia. AB - Individuals with congenital prosopagnosia (CP) are impaired at identifying individual faces but do not appear to show impairments in extracting the average identity from a group of faces (known as ensemble coding). However, possible deficits in ensemble coding in a previous study (CPs n = 4) may have been masked because CPs relied on pictorial (image) cues rather than identity cues. Here we asked whether a larger sample of CPs (n = 11) would show intact ensemble coding of identity when availability of image cues was minimised. Participants viewed a "set" of four faces and then judged whether a subsequent individual test face, either an exemplar or a "set average", was in the preceding set. Ensemble coding occurred when matching (vs. mismatching) averages were mistakenly endorsed as set members. We assessed both image- and identity-based ensemble coding, by varying whether test faces were either the same or different images of the identities in the set. CPs showed significant ensemble coding in both tasks, indicating that their performance was independent of image cues. As a group, CPs' ensemble coding was weaker than controls in both tasks, consistent with evidence that perceptual processing of face identity is disrupted in CP. This effect was driven by CPs (n= 3) who, in addition to having impaired face memory, also performed particularly poorly on a measure of face perception (CFPT). Future research, using larger samples, should examine whether deficits in ensemble coding may be restricted to CPs who also have substantial face perception deficits. PMID- 29454896 TI - Functional magnetic resonance imaging of divergent and convergent thinking in Big C creativity. AB - The cognitive and physiological processes underlying creativity remain unclear, and very few studies to date have attempted to identify the behavioral and brain characteristics that distinguish exceptional ("Big-C") from everyday ("little-c") creativity. The Big-C Project examined functional brain responses during tasks demanding divergent and convergent thinking in 35 Big-C Visual Artists (VIS), 41 Big-C Scientists (SCI), and 31 individuals in a "smart comparison group" (SCG) matched to the Big-C groups on parental educational attainment and estimated IQ. Functional MRI (fMRI) scans included two activation paradigms widely used in prior creativity research, the Alternate Uses Task (AUT) and Remote Associates Task (RAT), to assess brain function during divergent and convergent thinking, respectively. Task performance did not differ between groups. Functional MRI activation in Big-C and SCG groups differed during the divergent thinking task. No differences in activation were seen during the convergent thinking task. Big-C groups had less activation than SCG in frontal pole, right frontal operculum, left middle frontal gyrus, and bilaterally in occipital cortex. SCI displayed lower frontal and parietal activation relative to the SCG when generating alternate uses in the AUT, while VIS displayed lower frontal activation than SCI and SCG when generating typical qualities (the control condition in the AUT). VIS showed more activation in right inferior frontal gyrus and left supramarginal gyrus relative to SCI. All groups displayed considerable overlapping activation during the RAT. The results confirm substantial overlap in functional activation across groups, but suggest that exceptionally creative individuals may depend less on task-positive networks during tasks that demand divergent thinking. PMID- 29454897 TI - Involvement of eIF2alpha of Epinephelus coioides in the fish immune response to virus infection. AB - The eukaryotic initiation factor 2 alpha subunit (eIF2alpha) is a key translation regulator that plays an important role in different cellular pressures and stimuli, including virus infection. In the present study, an eIF2alpha homolog (EceIF2alpha) from the orange-spotted grouper (Epinephelus coioides) was cloned and its roles during fish viral infection were characterized. EceIF2alpha encodes a putative protein of 315 amino acid residues, and shares a high degree of similarity with eIF2alphas from other species. Quantitative real-time polymerase chain reaction (qRT-PCR) analysis indicated that EceIF2alpha was distributed in all examined tissues. Both of the expression levels of EceIF2alpha in the spleen and head kidney of E. coioides were up-regulated when challenged with polyinosine polycytidylic acid (poly[I:C]). EceIF2alpha was abundantly distributed in both the cytoplasm and nucleus in grouper spleen (GS) cells. Over-expression of EceIF2alpha improved the expression of red-spotted grouper nervous necrosis virus (RGNNV) genes in GS cells. In addition, EceIF2alpha depressed the activation of NK-kappaB and IFN-beta. Furthermore, dephosphorylation inhibitor treatment led to a significant decrease of RGNNV gene transcription. Taken together, these results suggest that EceIF2alpha might be involved in the fish immune response to virus challenge. PMID- 29454898 TI - Dietary values of Forsythia suspensa extract in Penaeus monodon under normal rearing and Vibrio parahaemolyticus 3HP (VP3HP) challenge conditions: Effect on growth, intestinal barrier function, immune response and immune related gene expression. AB - Two trials were conducted to determine the effects of dietary Forsythia suspensa extract (FSE) on shrimp, Penaeus monodon, first on growth performance, second on the immune response and immune related gene expression of shrimp. In trial 1, shrimp (mean initial wet weight about 3.02 g) were fed with five diets containing 0% (basal diet), 0.01%, 0.02%, 0.04% and 0.06% FSE in triplicate for 60 days. Growth performance (final body wet weight, FBW; weight gain, WG; biomass gain, BG) of shrimp fed FSE diets were higher (P < 0.05) than that of shrimp fed the basal diet. The survival among all the diets treatments were above 90% and no significant difference was revealed among them (P > 0.05). The antioxidant capacity (total antioxidant status, TAS; glutathione peroxidase, GSH-Px) appears in the trend of firstly increasing then decreasing with the increasing of dietary FSE levels. The highest value of TAS and GSH-Px were found in shrimp fed 0.02% FSE diet and were significantly higher than that of shrimp fed the basal and 0.06% FSE diets (P < 0.05). Hepatopancreas malondialdehyde (MDA) of shrimp fed FSE diets were lower (P < 0.05) than that of shrimp fed the basal diet. Total haemocyte count of shrimp fed the basal diet was lower (P < 0.05) than that of shrimp fed FSE diets. Haemolymph clotting time of shrimp had the opposite trend with the total haemocyte count of shrimp. No significant differences were found in haemolymph biomarkers of intestinal permeability (endotoxin and diamine oxidase) and in molecular gene expression profiles of heat shock protein 70 (Hsp 70) mRNA and hypoxia inducible factor-1alpha (HIF-1alpha) mRNA in haemolymph of shrimp among all diet treatments (P > 0.05). In trial 2, a pathogenic strain of Vibrio parahaemolyticus 3HP (VP3HP) injection challenge test was conducted for 6 day after the rearing trial and shrimp survival were also compared among treatments. Survival of shrimp fed diets supplemented with 0.01%-0.02% FSE were higher than that of shrimp fed the basal and 0.06% FSE diets (P < 0.05). Dietary FSE supplementation produced stronger hepatopancreas antioxidant capacity (TAS, GSH-Px) (P < 0.05) and higher glutathione (GSH) level (P < 0.05), lower superoxide dismutase activity (SOD) (P < 0.05), higher total haemocyte count (P < 0.05), lower haemolymph clotting time (P < 0.05), lower MDA and carbonyl protein concentration (P < 0.05), lower haemolymph biomarkers of intestinal permeability (endotoxin and diamine oxidase) (P < 0.05), generated lower molecular gene expression profiles of HSP 70 mRNA and higher HIF-1alpha mRNA (P < 0.05) than the basal diet. The immune response were characterized by lower TAS and higher antioxidant enzyme activities (SOD, GSH-Px) and higher oxidative stress level (MDA and carbonyl protein) and higher haemolymph biomarkers of intestinal permeability (endotoxin and diamine oxidase) compared to levels found in trail 1. However, the total haemocyte counts and haemolymph clotting times were not changed in 0.01%-0.02% FSE diets treatments between trial 1 and trial 2 (P > 0.05). The molecular gene expression profile of Hsp 70 mRNA was increased while HIF-1alpha mRNA was decreased when compared to trial 1. In conclusion, results suggested that dietary intake containing FSE could enhance the growth performance and antioxidant capacity of P. monodon and furthermore reduce oxidative stress and immune depression challenged by a pathogenic strain of Vibrio parahaemolyticus stress. Considering the effect of FSE on both growth performance and immune response of P. monodon, the level of FSE supplemented in the diet should be between 0.01% and 0.02%.

AB - BACKGROUND: Photodynamic therapy (PDT) is a good option for the treatment of Bowen's disease (BD). However, BD occasionally can progress into a squamous cell carcinoma (SCC) after PDT. OBJECTIVE: Find predictors of aggressiveness of BD after PDT METHODS: Two biopsies of patients with BD treated with PDT with progression to SCC within three months were selected for immunohistochemical (IHC) studies. Conventional PDT was applied. IHC analysis was performed together with hematoxylin-eosin in the biopsies prior to and after treatment with PDT. RESULTS: Among the IHC markers studied, none showed different expressions between pre-treatment and post-treatment biopsies except for HSP70 CONCLUSIONS: The expression of Hsp70 in BD may predict future aggressive behaviour in BD when treated with PDT. Nevertheless, due to the small number of biopsies studied, further investigations are required to draw conclusions.

AB - Bacterial infections have been a major challenge to health. Increasing resistance to antimicrobial agents, according to World Health Organization, could be the major cause of death until 2050. Photodynamic therapy emerges as an alternative in microbial inactivation, due to its selectivity and to decreasing or dismissing antibiotic use. This study aimed at evaluating, in vitro, the internalization of the Methylene Blue and its photodynamic activity against a clinical and ATCC strain of Pseudomonas aeruginosa and Staphyloccocus aureus. Thus, the strains were incubated with MB in concentrations of 100, 300 e 500 MUg/ml and then irradiated with a LED (+/-660 nm) at fluence of 10 and 25 J/cm2. The MB internalization was evaluated using a confocal microscope (Zeiss LSM 700), to capture the MB and the DAPI (for DNA staining). It was possible to observe that the MB was internalized by the bacterial cells, in all concentrations tested. The CFU/ml count demonstrated significant reduction (p <= 0,01) at the average 5.0 logs comparing with control group for the two species in all the tested concentrations. In conclusion, the strains tested were capable of internalizing the MB. PDT with MB was able to decrease the growth of the tested strains in vitro, being a promising alternative to the future treatment of infections caused by these species.

AB - Increased expression of syndecan-1 is a characteristic feature of human liver cirrhosis. However, no data are available on the significance of this alteration. To address this question we designed a transgenic mouse strain that driven by albumin promoter, expresses human syndecan-1 in the hepatocytes. Liver cirrhosis was induced by thioacetamide in wild type and hSDC1+/+ mice of the identical strain. The process of fibrogenesis, changes in signal transduction and proteoglycan expression were followed. In an in vitro experiment, the effect of syndecan-1 overexpression on the action of TGFbeta1 was determined. Human syndecan-1 and TGFbeta1 levels were measured by ELISA in the circulation. Without challenge, no morphological differences were observed between wild type and transgenic mice livers, although significant upregulation of phospho-Akt and FAK was observed in the latter. Fibrogenesis in the transgenic livers, characterized by picrosirius staining, collagen type I, and SMA levels, lagged behind that of control in the first and second months. Changes in signal transduction involved in the process of fibrogenesis, as SMAD, MAPK, Akt and GSK, pointed to the decreased effect of TGFbeta1, and this was corroborated by the decreased mRNA expression of TIEG and the growth factor itself. In vitro experiments exposing the LX2 hepatic stellate cell line to conditioned media of wild type and syndecan 1 transfected Hep3B cell lines proved that medium with high syndecan-1 content inhibits TGFbeta1-induced upregulation of SMA, TIEG, collagen type I and thrombospondin-1 expression. Detection of liver proteoglycans and heparan sulfate level revealed that their amounts are much higher in control transgenic liver, than that in the wild type. However, it decreases dramatically as a result of shedding after hepatic injury. Shedding is likely promoted by the upregulation of MMP14. As syndecan-1 can bind thrombospondin-1, and as our result demonstrated that the same is true for TGFbeta1, shed syndecan-1 can remove the growth factor and its activator together into the systemic circulation.Taking together, our results indicate that the effect of syndecan-1 is accomplished on two levels: a, the shedded syndecan can bind, inhibit and remove TGFbeta1; b, interferes with the activation of TGFbeta1 by downregulation and binding thrombospondin-1, the activator of the growth factor. However, by the end of the fourth month the protective effect was lost, which is explained by the considerable decrease of syndecan-1 and the almost complete loss of heparan sulfate from the surface of hepatocytes. PMID- 29454903 TI - Estrogen receptor-alpha isoforms are the main estrogen receptors expressed in non small cell lung carcinoma. AB - The expression profile of estrogen receptors (ER) in Non-Small Cell Lung Carcinoma (NSCLC) remains contradictory. Here we investigated protein and transcriptome expression of ERalpha wild type and variants. Tissue Micro-Arrays of 200 cases of NSCLC (paired tumor/non-tumor) were assayed by immunohistochemistry using a panel of ERalpha antibodies targeting different epitopes (HC20, 6F11, 1D5, ERalpha36 and ERalpha17p). ERbeta epitopes were also examined for comparison. In parallel we conducted a probe-set mapping (Affymetrix HGU133 plus 2 chip) meta-analysis of 12 NSCLC tumor public transcriptomic studies (1418 cases) and 39 NSCLC cell lines. Finally, we have investigated early transcriptional effects of 17beta-estradiol, 17beta-estradiol-BSA, tamoxifen and their combination in two NSCLC cell lines (A549, H520). ERalpha transcript and protein detection in NSCLC specimens and cell lines suggests that extranuclear ERalpha variants, like ERalpha36, prevail, while wild-type ERalpha66 is minimally expressed. In non-tumor lung, the wild-type ERalpha66 is quasi-absent. The combined evaluation of ERalpha isoform staining intensity and subcellular localization with sex, can discriminate NSCLC subtypes and normal lung. Overall ERalpha transcription decreases in NSCLC. ERalpha expression is sex-related in non-tumor tissue, but in NSCLC it is exclusively correlating with tumor histologic subtype. ERalpha isoform protein expression is higher than ERbeta. ERalpha isoforms are functional and display specific early transcriptional effects following steroid treatment. In conclusion, our data show a wide extranuclear ERalpha-variant expression in normal lung and NSCLC that is not reported by routine pathology ER evaluation criteria, limited in the nuclear wild type receptor. PMID- 29454904 TI - Protective effect of sodium stearate on the moisture-induced deterioration of hygroscopic spray-dried powders. AB - Amorphous powders are thermodynamically unstable, significantly impacting the processing, storage and performance of a product. Therefore, stabilization of the amorphous contents is in demand. In this study, disodium cromoglycate (DSCG) powder was chosen as a model drug because it is amorphous and highly hygroscopic after spray drying. Sodium stearate (NaSt) was co-spray dried with DSCG at various concentrations (10, 50 and 90% w/w) to investigate its effect against moisture-induced deterioration on the in vitro aerosolization performance of DSCG. Particle size distribution and morphology were measured by laser diffraction and scanning electron microscopy (SEM). Physicochemical properties of the powders were analysed by X-ray powder diffraction (XRPD) and dynamic vapour sorption (DVS). Particle surface chemistry was analysed by the time-of-flight secondary ion mass spectrometry (ToF-SIMS). In vitro dissolution behaviours of the spray-dried (SD) powders were tested by the Franz cell apparatus. In vitro aerosolization performance of SD formulations stored at different relative humidity (RH) was evaluated by a multi-stage liquid impinger (MSLI), using an Osmohaler(r) at 100 L/min. Results showed that adding NaSt in the formulation not only increased the aerosolization performance of DSCG significantly, but also effectively reduced the deleterious impact of moisture. No significant difference was found in the fine particle fraction (FPF) of formulations containing NaSt before and after storage at both 60% and 75% RH for one week. However, after one month storage at 75% RH, SD formulation containing 10% NaSt showed a reduction in FPF, while formulations containing 50% or 90% NaSt showed no change. The underlying mechanism was that NaSt increased the crystallinity of the powders and its presence on the particle surface reduced particle aggregations and cohesiveness. However, NaSt at high concentration could reduce dissolution rate, which needs to be taken into consideration. PMID- 29454905 TI - Relationships between surface coverage ratio and powder mechanics of binary adhesive mixtures for dry powder inhalers. AB - The aim of this paper was to study relationships between the content of fine particles and the powder mechanics of binary adhesive mixtures and link these relationships to the blend state. Mixtures with increasing amounts of fine particles (increasing surface coverage ratios (SCR)) were prepared using Lactopress SD as carrier and micro particles of lactose as fines (2.7 um). Indicators of unsettled bulk density, compressibility and flowability were derived and the blend state was visually examined by imaging. The powder properties studied showed relationships to the SCR characterised by stages. At low SCR, the fine particles predominantly gathered in cavities of the carriers, giving increased bulk density and unchanged or improved flow. Thereafter, increased SCR gave a deposition of particles at the enveloped carrier surface with a gradually more irregular adhesion layer leading to a reduced bulk density and a step-wise reduced flowability. The mechanics of the mixtures at a certain stage were dependent on the structure and the dynamics of the adhesion layer and transitions between the stages were controlled by the evolution of the adhesion layer. It is advisable to use techniques based on different types of flow in order to comprehensively study the mechanics of adhesive mixtures.

AB - OBJECTIVES: Treating infections of Gram-negative pathogens, in particular Pseudomonas aeruginosa, is a challenge for clinicians in the Asia-Pacific region owing to inherent and acquired antimicrobial resistance. This systematic review and meta-analysis provides updated information on risk factors for P. aeruginosa infection in Asia-Pacific as well as the consequences (e.g. mortality, costs) of initial inappropriate antimicrobial therapy (IIAT). METHODS: Embase and MEDLINE databases were searched for Asia-Pacific studies reporting the consequences of IIAT versus initial appropriate antimicrobial therapy (IAAT) in Gram-negative bacterial infections as well as risk factors for serious P. aeruginosa infection. A meta-analysis of unadjusted mortality was performed using a random-effects model. RESULTS: A total of 22 studies reporting mortality and 13 reporting risk factors were identified. The meta-analysis demonstrated that mortality was significantly lower in patients receiving IAAT versus IIAT, with a 67% reduction observed for 28- or 30-day all-cause mortality (odds ratio=0.33, 95% confidence interval 0.20-0.55; P<0.001). Risk factors for serious P. aeruginosa infection include previous exposure to antimicrobials, mechanical ventilation and previous hospitalisation. CONCLUSION: High rates of antimicrobial resistance in Asia Pacific as well as the increased mortality associated with IIAT and the presence of risk factors for serious infection highlight the importance of access to newer and appropriate antimicrobials.

AB - Sediment bacterial communities play a critical role in biogeochemical cycling in lotic ecosystems. Despite their ecological significance, the effects of urban discharge on spatiotemporal distribution of bacterial communities are understudied. In this study, we examined the effect of urban discharge on the spatiotemporal distribution of stream sediment bacteria in a northeast Ohio stream. Water and sediment samples were collected after large storm events (discharge > 100 m) from sites along a highly impacted stream (Tinkers Creek, Cuyahoga River watershed, Ohio, USA) and two reference streams. Although alpha (alpha) diversity was relatively constant spatially, multivariate analysis of bacterial community 16S rDNA profiles revealed significant spatial and temporal effects on beta (beta) diversity and community composition and identified a number of significant correlative abiotic parameters. Clustering of upstream and reference sites from downstream sites of Tinkers Creek combined with the dominant families observed in specific locales suggests that environmentally-induced species sorting had a strong impact on the composition of sediment bacterial communities. Distinct groupings of bacterial families that are often associated with nutrient pollution (i.e., Comamonadaceae, Rhodobacteraceae, and Pirellulaceae) and other contaminants (i.e., Sphingomonadaceae and Phyllobacteriaceae) were more prominent at sites experiencing higher degrees of discharge associated with urbanization. Additionally, there were marked seasonal changes in community composition, with individual taxa exhibiting different seasonal abundance patterns. However, spatiotemporal variation in stream conditions did not affect bacterial community functional profiles. Together, these results suggest that local environmental drivers and niche filtering from discharge events associated with urbanization shape the bacterial community structure. However, dispersal limitations and interactions among other species likely play a role as well. PMID- 29454908 TI - The ranking of scientists. PMID- 29454909 TI - Letters to the Editor.

AB - ETHNOPHARMACOLOGICAL RELEVANCE: Bidens pilosa L, belonging to the family of Acanthaceae, has been used as an anticancer medicine in folk in China. In our preliminary experiments, the petroleum ether extract from B. pilosa showed good cytotoxic activity to human lung cancer A549 cell. However, to date, it's lack of the further study on antitumor effect, mechanism and active substances composition of the petroleum ether extract of B. pilosa. AIM OF THE STUDY: The study aimed to evaluate the anti-lung cancer efficacy of the petroleum ether extract from B. pilosa (PEEBP) in vitro and in vivo, explore the possible anticancer mechanisms, and further disclose the chemical composition of the extract. MATERIALS AND METHODS: B. pilosa was extracted with 75% ethanol (v/v), followed by extracted with petroleum ether to obtain the objective fraction. Antiproliferation effect of the petroleum ether extract in HepG2, A549, CNE and B16 cells was evaluated by MTT assay. The in vivo anticancer effect was examined by A549 cells nude mice xenograft tumor model. The possible effect mechanism was studied by western blot assay. The chemical constituents of the extract was analyzed by GC-MS. RESULTS: The petroleum ether extract showed favorable antiproliferation activity against the four human cancer cell lines, especially for A549 cells with an IC50 of 49.11 +/- 2.72 MUg/mL. The extract inhibited the growth of A549 cell in mice with the inhibitory rates of 24.76%, 35.85% and 53.07% for 90, 180 and 360 mg/kg oral dosages, respectively. The B. pilosa extract could significantly down-regulate the expression of apoptosis-related protein Bcl-2 and up-regulate the protein expression of Bax and Caspase-3. 138 compounds were identified by GC-MS in the extract and the main chemical components were triterpenes, including 4,22-cholestadien-3-one (4.82%), stigmasterol (4.56%), friedelan-3-one (3.28%), etc. CONCLUSION: The PEEBP is abundant of triterpenes and has significant anti-tumor activities against human A549 cells in vitro and in vivo, indicating it a potential anticancer agent. PMID- 29454913 TI - Restoring Th17/Treg balance via modulation of STAT3 and STAT5 activation contributes to the amelioration of chronic obstructive pulmonary disease by Bufei Yishen formula. AB - ETHNOPHARMACOLOGY RELEVANCE: Bufei Yishen formula (BYF), a Traditional Chinese Medicine (TCM), has been extensively applied in clinical treatment of chronic obstructive pulmonary disease (COPD) and provides an effective treatment strategy for the syndrome of lung-kidney qi deficiency in COPD patients. Here, we investigated its anti-COPD mechanism in COPD rats in relation to the balance between T helper (Th) 17 cells and regulatory T (Treg) cells. METHODS: Rat model of cigarette smoke- and bacterial infection-induced COPD was established, and orally treated with BYF for 12 consecutive weeks. Then, the rats were sacrificed, their lung tissues were removed for histological analysis, and spleens and mesenteric lymph nodes (MLNs) were collected to evaluate the Th17 and Treg cells. RESULTS: Oral treatment of BYF markedly suppressed the disease progression and alleviated the pathological changes of COPD. It also decreased the bronchoalveolar lavage fluid (BALF) levels of pro-inflammatory cytokines, including IL-1beta, IL-6, TNF-alpha and Th17-related IL-17A, and induced a significant increase in Treg-related IL-10. Furthermore, BYF treatment obviously decreased the proportion of CD4+RORgammat+ T (Th17) cell and increased the proportion of CD4+CD25+Foxp3+ T (Treg) cell, leading to restore the Th17/Treg balance. BYF treated groups also decreased RORgammat and increased Foxp3 expression in the spleens and MLNs. BYF further inhibited the phosphorylation of signal transducer and activator of transcription-3 (STAT3) and boosted the phosphorylation of STAT5, that were critical transcription factors for TH17 and Treg differentiation. CONCLUSION: these results demonstrated that BYF exerted its anti-COPD efficacy by restoring Th17/Treg balance via reciprocally modulating the activities of STAT3 and STAT5 in COPD rats, which may help to elucidate the underlying immunomodulatory mode of BYF on COPD treatment. PMID- 29454914 TI - Substituting one Paris for another? In vitro cytotoxic and in vivo antitumor activities of Paris forrestii, a substitute of Paris polyphylla var. yunnanensis. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Chong-lou (Paris polyphylla var. yunnanensis or P. polyphylla var. chinensis) is traditionally used as an anticancer medicine in China. It is also the material basis of some Chinese patent anticancer medicines, such as Gan-Fu-Le capsules, Bo-Er-Ning capsules, Lou-Lian capsules, Ruan-Jian oral liquid, and Qi-Zhen capsules. P. forrestii, a substitute for Chong-lou, is planted at a large scale in the Yunnan Province of China. AIM OF THE STUDY: To clarify the active chemical constituents of P. forrestii and evaluate the in vitro and in vivo anticancer activities of the total saponins from P. forrestii. MATERIALS AND METHODS: The total saponins of P. forrestii were extracted and separated to yield pure compounds by chromatographic techniques, and the structures of the isolates were elucidated by spectroscopic methods. The cytotoxicity of the crude extracts, total saponins, and chemical constituents were evaluated using an MTS assay. In vivo antitumor activities of the total saponins from P. forrestii were measured using H22 tumor-bearing mice by intraperitoneal (ip) administration. RESULTS: Eight compounds, including polyphyllin D (1), formosanin C (2), dioscin (3), diosgenin-3-O-alpha-l rhamnopyranosyl-(1->2)-beta-d-glucopyranoside (4), paris saponin H (5), pennogenin-3-O-alpha-l-rhamnopyranosyl-(1->2)-[alpha-l-rhamnopyranosyl-(1->4)] beta-d-glucopyranoside (6), pariposide A (7), and crustecdysone (8), were isolated from the total saponins of P. forrestii. The total saponins and compounds 1-6 showed significant inhibitory activity against the growth of the HL 60, SMMC-7721, A-549, MCF-7, and SW480 cell lines. The total saponins from P. forrestii had a tumor-inhibitory effect in H22 tumor-bearing mice upon ip (2.25 mg/kg dose) administration, with an inhibition rate of 42.6% compared with cisplatin (ip, 2 mg/kg dose, 53.9% inhibition rate). CONCLUSION: The results support that P. forrestii could be a substitute for P. polyphylla var. yunnanensis as an anticancer medicine. PMID- 29454915 TI - Synthesis of N-(1-(6-acetamido-5-phenylpyrimidin-4-yl) piperidin-3-yl) amide derivatives as potential inhibitors for mitotic kinesin spindle protein. AB - Kinesin Spindle Protein (KSP) or Eg5 is an essential kinesin that is involved in spindle separation process during mitosis and also unregulated in certain cancer cells. Inhibitors of this enzyme have proved to be effective to block spindle separation followed by mitotic arrest and apoptosis of the cancer cells. Since this enzyme has two allosteric inhibitor binding sites, it's an excellent target for developing drugs for cancer chemotherapy. Many pyrimidine derivatives have been proved to be active against cancer and other enzymes. In this report, we have synthesized a set ten novel N-(1-(6-acetamido-5-phenylpyrimidin-4 yl)piperidin-3-yl)amide derivatives and have evaluated their activity against the KSP. The SAR of these active compounds was further analyzed using in silico molecular docking studies using GOLD and AutoDock softwares. All these compounds form hydrophobic interaction, aromatic pi-pi stacking and hydrogen bond efficiently with the Eg5. PMID- 29454916 TI - Mitochondria-targeting indolizino[3,2-c]quinolines as novel class of photosensitizers for photodynamic anticancer activity. AB - To achieve efficient photodynamic activity, substantial effort has been dedicated to precise control of the intracellular localization of current photosensitizers (PSs). Given the extremely small radius of action of singlet oxygen, the direct targeting of PSs to the mitochondria is expected to greatly enhance the photodynamic therapy (PDT) activity. Here, we report mitochondria-targeting 6 (furan-2-yl)- and 6-(thiophen-2-yl) indolizino[3,2-c]quinolines (IQs) as novel PSs. IQ derivatives containing 5-membered heterocyclic aromatic rings were synthesized, and their photophysical properties as PSs were characterized. The anticancer potentials of 2a-2f were investigated using various cancer cell lines, and they exhibited dose-dependent and light exposure time-dependent cytotoxicity. Among the synthesized compounds, 2b, which contains a furan ring, showed dual functions as an imaging probe as well as a PS. Real-time confocal fluorescence images revealed the mitochondrial localization of 2b as a primary site of photodamage in live cells. Targeted reactive oxygen species (ROS)-generation capabilities and the photoinduced DNA cleavage of IQs led to mitochondrial dysfunction and photoinduced apoptosis via the intrinsic pathway. 3D RI tomograms of individual live HeLa cells treated with 2b showed that the progress of photoinduced apoptosis was affected by the PS concentration and light irradiation time. The studied IQs (2b, 2d, and 2e) are expected to serve as a new class of heavy-atom-free PSs with low molecular weights less than 350. PMID- 29454917 TI - Marine derived xyloketal derivatives exhibit anti-stress and anti-ageing effects through HSF pathway in Caenorhabditis elegans. AB - Ageing is a complex but universal phenomenon that progressively challenges the homeostasis network and finally leads to the dysfunction of organisms and even death. Previous studies demonstrated that xyloketal B and its derivatives, a series of marine novel ketone compounds, possessed unique antioxidative effects on endothelial and neuronal oxidative injuries. In this study, we examined the effects of xyloketal derivatives on extending lifespan and healthspan of Caenorhabditis elegans. The results showed that most selected xyloketals could protect Caenorhabditis elegans against heat stress and extend the lifespan of worms. Compound 15, a benzo-1, 3-oxazine xyloketal derivative, possessed most potent effect in anti-heat stress assay and significantly attenuated ageing related decrease of pumping and bending of the worms in healthspan assay. In addition, the beneficial effect of 15 was abolished in PS3551 worms, a strain that possesses non-functional heat shock transcription factor-1 (HSF-1). Furthermore, 15 increased the expression of heat shock protein 70 (HSP70), a downstream molecular chaperone of HSF-1. These results indicated that HSF-1 might contribute to the protective effect of this compound in Caenorhabditis elegans ageing. Molecular docking studies suggested that these xyloketal derivatives were bound to the DNA binding domain of HSF-1, promoted the conformation of HSF-1, thus strengthened the interaction between the HSF-1 and related DNA. ALA-67, ASN 74 and LYS-80 of binding region might be the key amino residues during the interaction. Finally, compound 15 could reduce the paralysis of the CL4176 worms, a transgenic strain expressing human Abeta3-42 under a temperature-inducible system. Collectively, these data indicate that xyloketals have potential implications for further evaluation in anti-ageing studies. PMID- 29454918 TI - Design, synthesis, and biological evaluation of novel amide and hydrazide based thioether analogs targeting Histone deacteylase (HDAC) enzymes. AB - Development of HDAC inhibitors have become an ultimate need targeting different types of cancer. In silico virtual screening was applied to screen novel scaffolds via scaffold hopping strategy to develop different acrylamide and aryl/heteroaryl hydrazide based analogs merged with thioether moiety. The acrylamide based analogs showed significant hydrophobic interaction within binding pocket in addition to co-ordination with Zn+2 via carbonyl group, however the aryl/heteroaryl hydrazide based analogs showed binding towards Zn+2 via thiol moiety. Two classes (acrylamide and aryl/heteroaryl hydrazide based analogs) were synthesized to be screened along with 60 cancer cell lines panel to reveal that both of AHM-4 and AHM-5 showed significant inhibitory growth against HL-60 (Leukemia cell lines) at GI50 2.87 MUM and 3.20 MUM, respectively and MDA-MB-435 (Melanoma cell lines) cell lines at GI50 of 0.37 MUM and 0.42 MUM, respectively. AHM-4 and AHM-5 showed general inhibitory profile against class I HDAC enzymes with differential inhibitory activity towards HDAC 2 at IC50 32 nM and 20 nM, respectively via ELISA enzymatic assay, in addition to inhibiting activity for the expression of class I HDAC enzymes via real time PCR with differential selective inhibition against HDAC 2 up to 10 folds, compared to control. AHM4 and AHM5 showed cell cycle arrest action at G2/M phase along with induction of apoptosis via assessment of apoptotic parameters such as Caspase 3, 9, and gamma- H2AX. The synthesized analogs offer novel scaffold to be further optimized for development of HDAC inhibitors. PMID- 29454919 TI - Structure-activity relationships of talaumidin derivatives: Their neurite outgrowth promotion in vitro and optic nerve regeneration in vivo. AB - (-)-Talaumidin (1), a 2,5-biaryl-3,4-dimethyltetrahydrofuran lignan, shows potent neurotrophic activities such as neurite-outgrowth promotion and neuroprotection. Previously, we found that (-)-(1S,2R,3S,4R)-stereoisomer 2 exhibited more significant activity than did the natural product talaumidin (1). However, the preparation of optically active (-)-2 requires a complicated synthetic route. To explore new neurotrophic compounds that can be obtained on a large scale, we established a short step synthetic route for talaumidin derivatives and synthesized fourteen analogues based on the structure of (-)-2. First, we synthesized a racemic compound of (-)-2 (2a) and assessed its neurotrophic activity. We found that the neurotrophic property of racemic 2a is similar in activity to that of (-)-2. Using the same synthetic methodology, several talaumidin derivatives were synthesized to optimize the oxy-functionality on aromatic rings. As a result, bis(methylenedioxybenzene) derivative 2b possessed the highest neurotrophic activity. Furthermore, examination of the structure activity relationships of 2b revealed that the 2,5-diphenyl-tetrahydrofuran structure was an essential structure and that two methyl groups on THF ring could enhance neurotrophic activity. In addition, compounds 2a and 2b were found to induce mouse optic nerve regeneration in vivo. PMID- 29454920 TI - Design, synthesis and identification of silicon-containing HCV NS5A inhibitors with pan-genotype activity. AB - Modification of a HCV NS5A inhibitor, ombitasvir, led to the identification of 10d with improved pan-genotype NS5A inhibition and better pharmacokinetic properties. The key structural changes to ombitasvir include bioisosteric replacement of carbon with silicon atom. Compared with ombitasvir, the activity of anti-HCV genotypes (GT 1 to 6) of 10d is increased to some extent, especially the inhibitory activity against genotype 3a and 6a is increased by more than seven times, and the dog's in vivo pharmacokinetics properties were also superior to ombitasvir. Further drug evaluation showed that 10d was similar to ombitasvir on plasma protein binding and liver distribution profiles, with no cytotoxicity and no inhibitory effect on both CYP 450 and hERG ligand binding. However, permeability assay results indicated that 10d was not the substrate of P-gp or BCRP transporter, which is different from that of ombitasvir. The results of a 14 day repeat-dose toxicity study identified no toxicity with 10d. Our findings in preclinical tests suggest that the silicon-containing compound 10d could be worthy of continued study as a potential drug candidate. PMID- 29454921 TI - Sequential pretreatment for cell disintegration of municipal sludge in a neutral Bio-electro-Fenton system. AB - Sludge cell disruption was generally considered as the rate-limiting step for the anaerobic digestion of waste activated sludge (WAS). Advanced oxidation processes and bio-electro-chemical systems were recently reported to enhance the hydrolysis of WAS and sludge cell disruption, while the cell-breaking processes of these systems remain unclear yet. In this study, an innovative Bio-electro-Fenton system was developed to pretreat the WAS sequentially with cathode Fenton process and anode anaerobic digestion. Significant cell disruption and dissolution intracellular organics were founded after the treatment. X-ray photoelectron spectroscopy (XPS) analysis and fourier transform infrared spectroscopy (FT-IR) spectra indicated that Gram-negative bacteria were more sensitive to free radicals yielded in cathode to induce a chain reaction that destroyed the lipid contained outer membrane, while Gram-positive bacteria with thick peptidoglycan layer were liable to be biologically decomposed in the anode. Compared with the oxidation of organic matters in the cathode Fenton, the secretion of enzyme increased in the anode which was beneficial to break down the complex matters (peptidoglycans) into simples that were available for anode oxidation by exoelectrogens. The results also showed a possible prospect for the application of this sequential pretreatment in bio-electro-Fenton systems to disrupt sludge cells and enhance the anaerobic digestion. PMID- 29454922 TI - Nutrient recovery from wastewater through pilot scale electrodialysis. AB - Nutrient recovery performance utilising an electrodialysis (ED) process was quantified in a 30-cell pair pilot reactor with a 7.2 m2 effective membrane area, utilising domestic anaerobic digester supernatant, which had been passed through a centrifuge as a feed source (centrate). A concentrated product (NH4-N 7100 +/- 300 mg/L and K 2490 +/- 40 mg/L) could be achieved by concentrating nutrient ions from the centrate wastewater dilute feed stream to the product stream using the ED process. The average total current efficiency for all major cations over the experimental period was 76 +/- 2% (NH4-N transport 40%, K transport 14%). The electrode power consumption was 4.9 +/- 1.5 kWh/kgN, averaged across the three replicate trials. This value is lower than competing technologies for NH4-N removal and production, and far lower than previous ED lab trials, demonstrating the importance of pilot testing. No significant variation in starting flux densities and cell resistance voltage for subsequent replicate treatments indicated effective cleaning procedures and operational sustainability at treatment durations of several days. This study demonstrates that ED is an economically promising technology for the recovery of nutrients from wastewater. PMID- 29454923 TI - Seasonal differences in the content of phenols and pigments in thalli of freshwater Cladophora glomerata and its habitat. AB - Polyphenols are chemicals that primarily inhibit the growth of various autotrophic organisms. The presence of these metabolites greatly boosts the ecological dominance of eg. Cladophora, which creates large surface mats. The main goal of our work was to quantify the phenol and polyphenols (allelopathic substances) secreted by the macroalgae as a result of exposure to biotic stress caused by competition. The research was carried out on the Cladophora glomerata biomass collected from two freshwater ecosystems located in Wielkopolska Region (Poland, Fig. 1): Oporzynskie Lake (N52 degrees 55', E 17 degrees 9') and Nielba River (N5248', E 17 degrees 12'). Seasonal variability (May-October 2015) in the properties of C. glomerata mats in the river and lake ecosystem was also analyzed in relation to the physicochemical parameters of water. In addition, the content of pigments in the analyzed biomass was determined during the appearance of algae mats in water reservoirs. Biomass extraction was performed to determine the phenolic and carotenoid contents (chlorophyll and carotenoids) by using two extraction methods: microwave-assisted extraction (MAE) and supercritical fluid extraction (SFE). After isolation of the phenols from the thalli (mats) and the habitat, they were analyzed using the Folin-Ciocalteu method with some modifications, while the pigment content (chlorophyll and carotenoids) was evaluated by the spectrophotometric method Liechtenthaler (1987) with some variations. Analysis of the content of these components in algae extracts indicates that the tendency of changes in their contents was similar or the same. Growth and decrease of phenolic content (Cladophora T MAE and Cladophora T SFE) and pigments (MAE chlorophyll, SFE and MAE carotenoids) at the same time were independent of the insulation method used. The mats formed by C. glomerata on the surface of Lake Oporzynskie were more stable and larger surface area than those on the Nielba River, which could explain differences in polyphenol concentrations in these two aquatic ecosystems. The results suggest a reduction in the secretion of phenolic compounds with an aging population of algae.

AB - This work investigated impacts of iodide (I-) on the transformation of the widely used phenolic preservative methylparaben (MeP) as well as 11 other phenolic compounds by potassium permanganate (KMnO4). It was found that KMnO4 showed a low reactivity towards MeP in the absence of I- with apparent second-order rate constants (kapp) ranging from 0.065 +/- 0.0071 to 1.0 +/- 0.1 M-1s-1 over the pH range of 5-9. The presence of I- remarkably enhanced the transformation rates of MeP by KMnO4 via the contribution of hypoiodous acid (HOI) in situ formed, which displayed several orders of magnitude higher reactivity towards MeP than KMnO4. This enhancing effect of I- was greatly influenced by solution conditions (e.g., I- or KMnO4 concentration or pH), which could be well simulated by a kinetic model involving competition reactions (i.e., KMnO4 with I-, KMnO4 with MeP, HOI with KMnO4, and HOI with MeP). Similar enhancing effect of I- on the transformation kinetics of 5 other selected phenols (i.e., p-hydroxybenzoic acid, phenol, and bromophenols) at pH 7 was also observed, but not in the cases of bisphenol A, triclosan, 4-n-nonylphenol, and cresols. This discrepancy could be well explained by the relative reactivity of KMnO4 towards phenols vs I-. Liquid chromatography-tandem mass spectrometry analysis showed that iodinated aromatic products and/or iodinated quinone-like product were generated in the cases where I- enhancing effect was observed. Evolution of iodinated aromatic products generated from MeP (10 MUM) treated by KMnO4 (50-150 MUM) in the presence of I- (5-15 MUM) suggested that higher I- or moderate KMnO4 concentration or neutral pH promoted their formation. A similar enhancing effect of I- (1 MUM) on the transformation of MeP (1 MUM) by KMnO4 (12.6 MUM) and formation of iodinated aromatic products were also observed in natural water. This work demonstrates an important role of I- in the transformation kinetics and product formation of phenolic compounds by KMnO4, which has great implications for future applications of KMnO4 in treatment of I--containing water. PMID- 29454925 TI - A mechanistic study of stable dispersion of titanium oxide nanoparticles by humic acid. AB - Stable dispersion of nanoparticles with environmentally-friendly materials is important for their various applications including environmental remediation. In this study, we systematically examined the mechanisms of stable dispersion of two types of TiO2 nanoparticles (TNPs) with anatase and rutile crystalline structures by naturally occurring dissolved organic matter (humic acid) at different pHs, including at, below and above the Point of Zero Charge (PZC). The results showed that stable dispersion of TNPs by humic acid (HA) at all pHs tested can only be achieved with the assistance of ultra-sonication. The dispersion of TNPs by HA differed at the three pHs tested. Generally, HA greatly decreased the hydrodynamic diameters of TNPs at a very low concentration. The dispersion of TNPs became relatively stable when the HA concentration exceeded 5 mg/L, indicating that this HA concentration is required for stable dispersion of TNPs. The mechanisms involved in dispersion of TNPs by HA included electrostatic repulsion, steric hindrance and hydrophobic interaction. Electrostatic repulsion was identified to be the dominant mechanism. The dispersion of TNPs was enhanced when HA was added before ultra-sonication to avoid the partly irreversible re aggregation of TNPs after sonication. The crystalline phases and concentrations of TNPs were also found to influence their stable dispersion. The findings from this work enhance understanding of the combined effects of HA, pH, ultra sonication and crystalline structures of TNPs on their stable dispersion. The mechanisms identified can improve applications of TNPs in environmental water pollution control.

AB - Myocardial infarction (MI) occurs during a sustained insufficient blood supply to the heart, eventually leading to myocardial necrosis. Xin-Ke-Shu tablet (XKS) is a prescription herbal compound and a patented medicine extensively used in the clinical treatment of coronary heart disease (CHD). To understand the molecular mechanism of the XKS action against MI in detail, it is necessary to investigate the altered metabolome and related pathways coincident with clinical features. In this study, tissue-targeted metabonomics based on ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q TOF/MS) were developed to explore the metabolic changes associated with XKS treatment in the heart tissue of rats with MI induced by a left anterior descending coronary artery ligation (LAD). The metabolic disorder induced by LAD was alleviated after low-dose XKS (LD) and intermediate-dose XKS (MD) treatment. XKS modulated six perturbed metabolic pathways. Among them, inhibition of Ca2+ overload and dysfunction of fatty acid beta-oxidation-related metabolic pathways likely underlie the therapeutic effects of XKS against MI. In agreement with its observed effect on metabolite perturbation, XKS reversed the over-expression of the four key proteins, long-chain acyl-CoA synthetase 1 (ACSL1), carnitine palmitoyl transferase-1 (CPT1B), calcium/calmodulin-dependent kinase II (CaMKII), and phospholipase A2IIA (PLA2IIA). Both metabolite and protein changes suggested that XKS exerts its therapeutic effect on metabolic perturbations in LAD-induced MI mainly by inhibiting the Ca2+ overload and fatty acid beta-oxidation dysfunction. PMID- 29454927 TI - Syndemics among individuals enrolled in the PrEP Brasil Study. AB - BACKGROUND: Concurrent psychosocial problems may synergistically increase the risk of HIV infection (syndemics), representing a challenge for prevention. We aimed to evaluate the prevalence and associated factors of syndemics among men who have sex with men (MSM) and transgender women (TGW) enrolled in the Brazilian pre-exposure prophylaxis demonstration study (PrEP Brasil Study). METHODS: Secondary cross-sectional analysis of the PrEP Brasil Study was performed. Of 450 HIV-seronegative MSM/TGW enrolled in the PrEP Brasil Study- conducted at Rio de Janeiro and Sao Paulo, Brazil- 421 participants with complete data were included in the present analysis. Syndemics was defined as occurrence of >=2 of the following conditions: polysubstance (>=2) use, binge drinking, positive depression screen, compulsive sexual behavior, and intimate partner violence (IPV). RESULTS: The prevalence of recent polysubstance use was 22.8%, binge drinking 51.1%, positive depression screening 5.2%, compulsive sexual behavior 7.1%, and IPV 7.3%. Syndemics prevalence was 24.2%, and associated factors were younger age (adjusted Odds Ratio (aOR) 0.95, 95% Confidence Interval (95% CI) 0.92-0.98 per year increase), TGW vs. MSM (aOR 3.09, 95% CI: 1.2-8.0), some college education or more vs. less than college (aOR 2.49, 95% CI: 1.31-4.75), and multiple male sexual partners in prior 3 months (aOR 1.69, 95% CI: 0.92 3.14). CONCLUSION: Given the high prevalence of syndemics, particularly of polysubstance use and binge drinking, PrEP delivery offers an opportunity to diagnose and intervene in mental and social well-being. PMID- 29454930 TI - Expanding horizons of cryo-tomography to larger volumes. AB - The three dimensional ultrastructure of cells and tissues comes to light with tomography. There is an inherent tension between representing molecular detail at the highest possible resolution, on one hand, and visualizing spatial relations between large organelles or even neighboring cells in large volumes, on the other. Together with its advantages for pristine sample preservation, cryo tomography brings particular constraints. A major challenge has been the restriction to specimens thinner than the typical cell. New imaging modalities are now available to extend cryo-tomography to thicker specimens: cryo-scanning transmission electron tomography (CSTET), soft X-ray tomography (SXT), and serial surface imaging using the focused ion beam-scanning electron microscope (FIB SEM). Each one offers specific advantages so the optimal choice depends on priorities among resolution, composition, and volume. PMID- 29454929 TI - HuR-mediated SCN5A messenger RNA stability reduces arrhythmic risk in heart failure. AB - BACKGROUND: Downregulated sodium currents in heart failure (HF) have been linked to increased arrhythmic risk. Reduced expression of the messenger RNA (mRNA) stabilizing protein HuR (also known as ELAVL1) may be responsible for the downregulation of sodium channel gene SCN5A mRNA. OBJECTIVE: The purpose of this article was to investigate whether HuR regulates SCN5A mRNA expression and whether manipulation of HuR benefits arrhythmia control in HF. METHODS: Quantitative real-time reverse-transcriptase polymerase chain reaction was used to investigate the expression of SCN5A. Optical mapping of the intact heart was adopted to study the effects of HuR on the conduction velocity and action potential upstroke in mice with myocardial infarct and HF after injection of AAV9 viral particles carrying HuR. RESULTS: HuR was associated with SCN5A mRNA in cardiomyocytes, and expression of HuR was downregulated in failing hearts. The association of HuR and SCN5A mRNA protected SCN5A mRNA from decay. Injection of AAV9 viral particles carrying HuR increased SCN5A expression in mouse heart tissues after MI. Optical mapping of the intact heart demonstrated that overexpression of HuR improved action potential upstroke and conduction velocity in the infarct border zone, which reduced the risk of reentrant arrhythmia after MI. CONCLUSION: Our data indicate that HuR is an important RNA-binding protein in maintaining SCN5A mRNA abundance in cardiomyocytes. Reduced expression of HuR may be at least partially responsible for the downregulation of SCN5A mRNA expression in ischemic HF. Overexpression of HuR may rescue decreased SCN5A expression and reduce arrhythmic risk in HF. Increasing mRNA stability to increase ion channel currents may correct a fundamental defect in HF and represent a new paradigm in antiarrhythmic therapy. PMID- 29454928 TI - Resting state functional connectivity of the amygdala and problem drinking in non dependent alcohol drinkers. AB - Alcohol misuse is associated with dysfunction of the amygdala-prefrontal cortical circuit. The amygdala and its cortical targets show decreased activity during a variety of task challenges in individuals engaged in problem drinking. On the other hand, it is less clear how amygdala resting state functional connectivity (rsFC) may be altered in association with alcohol misuse and whether such changes are restricted to prefrontal cortical structures. Further, the influences of comorbid substance use and depression and potential sex differences have not been assessed in earlier work. Here, with fMRI data from a Nathan Kline Institute/Rockland sample of 83 non-dependent alcohol drinkers (26 men), we addressed changes in whole brain rsFC of the amygdala in association with problem drinking as indexed by an alcohol involvement score. Imaging data were processed with Statistical Parametric Mapping following standard routines and all results were examined at voxel p < 0.001 uncorrected in combination with cluster p < 0.05 corrected for false discovery rate. Alcohol misuse was correlated with decreased amygdala connectivity with the dorsal anterior cingulate cortex (dACC) irrespective of depression and other substance use. Changes in amygdala-dACC connectivity manifested in the latero-basal subdivision of the amygdala. Further, men as compared to women showed a significantly stronger relationship in decreased amygdala-dACC connectivity and problem drinking, although it should be noted that men also showed a trend toward higher alcohol involvement score than women. The findings add to a growing literature documenting disrupted amygdala prefrontal cortical functions in relation to alcohol misuse. PMID- 29454931 TI - The soil microbiome-from metagenomics to metaphenomics. AB - Soil microorganisms carry out important processes, including support of plant growth and cycling of carbon and other nutrients. However, the majority of soil microbes have not yet been isolated and their functions are largely unknown. Although metagenomic sequencing reveals microbial identities and functional gene information, it includes DNA from microbes with vastly varying physiological states. Therefore, metagenomics is only predictive of community functional potential. We posit that the next frontier lies in understanding the metaphenome, the product of the combined genetic potential of the microbiome and available resources. Here we describe examples of opportunities towards gaining understanding of the soil metaphenome. PMID- 29454933 TI - Effects of resting state condition on reliability, trait specificity, and network connectivity of brain function measured with arterial spin labeled perfusion MRI. AB - Resting state fMRI (rs-fMRI) provides imaging biomarkers of task-independent brain function that can be associated with clinical variables or modulated by interventions such as behavioral training or pharmacological manipulations. These biomarkers include time-averaged regional brain function as manifested by regional cerebral blood flow (CBF) measured using arterial spin labeled (ASL) perfusion MRI and correlated temporal fluctuations of function across brain networks with either ASL or blood oxygenation level dependent (BOLD) fMRI. Resting-state studies are typically carried out using just one of several prescribed state conditions such as eyes closed (EC), eyes open (EO), or visual fixation on a cross-hair (FIX), which may affect the reliability and specificity of rs-fMRI. In this study, we collected test-retest ASL MRI data during 4 resting state task conditions: EC, EO, FIX and PVT (low-frequency psychomotor vigilance task), and examined the effects of these task conditions on reliability and reproducibility as well as trait specificity of regional brain function. We also acquired resting-state BOLD fMRI under FIX and compared the network connectivity reliabilities between the four ASL conditions and the BOLD FIX condition. For resting-state ASL data, EC provided the highest CBF reliability, reproducibility, trait specificity, and network connectivity reliability, followed by EO, while FIX was lowest on all of these measures. PVT demonstrated lower CBF reliability, reproducibility and trait specificity than EO and EC. Overall network connectivity reliability was comparable between ASL and BOLD. Our findings confirm ASL CBF as a reliable, stable, and consistent measure of resting-state regional brain function and support the use of EC or EO over FIX and PVT as the resting-state condition. PMID- 29454932 TI - Preserved canonicality of the BOLD hemodynamic response reflects healthy cognition: Insights into the healthy brain through the window of Multiple Sclerosis. AB - The hemodynamic response function (HRF), a model of brain blood-flow changes in response to neural activity, reflects communication between neurons and the vasculature that supplies these neurons in part by means of glial cell intermediaries (e.g., astrocytes). Intact neural-vascular communication might play a central role in optimal cognitive performance. This hypothesis can be tested by comparing healthy individuals to those with known white-matter damage and impaired performance, as seen in Multiple Sclerosis (MS). Glial cell intermediaries facilitate the ability of neurons to adequately convey metabolic needs to cerebral vasculature for sufficient oxygen and nutrient perfusion. In this study, we isolated measurements of the HRF that could quantify the extent to which white-matter affects neural-vascular coupling and cognitive performance. HRFs were modeled from multiple brain regions during multiple cognitive tasks using piecewise cubic spline functions, an approach that minimized assumptions regarding HRF shape that may not be valid for diseased populations, and were characterized using two shape metrics (peak amplitude and time-to-peak). Peak amplitude was reduced, and time-to-peak was longer, in MS patients relative to healthy controls. Faster time-to-peak was predicted by faster reaction time, suggesting an important role for vasodilatory speed in the physiology underlying processing speed. These results support the hypothesis that intact neural-glial vascular communication underlies optimal neural and cognitive functioning. PMID- 29454934 TI - Time scale properties of task and resting-state functional connectivity: Detrended partial cross-correlation analysis. AB - Functional connectivity analysis is an essential tool for understanding brain function. Previous studies showed that brain regions are functionally connected through low-frequency signals both within the default mode network (DMN) and task networks. However, no studies have directly compared the time scale (frequency) properties of network connectivity during task versus rest, or examined how they relate to task performance. Here, using fMRI data collected from sixty-eight subjects at rest and during a stop signal task, we addressed this issue with a novel functional connectivity measure based on detrended partial cross correlation analysis (DPCCA). DPCCA has the advantage of quantifying correlations between two variables in different time scales while controlling for the influence of other variables. The results showed that the time scales of within network connectivity of the DMN and task networks are modulated in opposite directions across rest and task, with the time scale increased during rest vs. task in the DMN and vice versa in task networks. In regions of interest analysis, the within-network connectivity time scale of the pre-supplementary motor area - a medial prefrontal cortical structure of the task network and critical to proactive inhibitory control - correlated inversely with Barratt impulsivity and stop signal reaction time. Together, these findings demonstrate that time scale properties of brain networks may vary across mental states and provide evidence in support of a role of low frequency fluctuations of BOLD signals in behavioral control. PMID- 29454935 TI - Dynamic resting state fMRI analysis in mice reveals a set of Quasi-Periodic Patterns and illustrates their relationship with the global signal. AB - Time-resolved 'dynamic' over whole-period 'static' analysis of low frequency (LF) blood-oxygen level dependent (BOLD) fluctuations provides many additional insights into the macroscale organization and dynamics of neural activity. Although there has been considerable advancement in the development of mouse resting state fMRI (rsfMRI), very little remains known about its dynamic repertoire. Here, we report for the first time the detection of a set of recurring spatiotemporal Quasi-Periodic Patterns (QPPs) in mice, which show spatial similarity with known resting state networks. Furthermore, we establish a close relationship between several of these patterns and the global signal. We acquired high temporal rsfMRI scans under conditions of low (LA) and high (HA) medetomidine-isoflurane anesthesia. We then employed the algorithm developed by Majeed et al. (2011), previously applied in rats and humans, which detects and averages recurring spatiotemporal patterns in the LF BOLD signal. One type of observed patterns in mice was highly similar to those originally observed in rats, displaying propagation from lateral to medial cortical regions, which suggestively pertain to a mouse Task-Positive like network (TPN) and Default Mode like network (DMN). Other QPPs showed more widespread or striatal involvement and were no longer detected after global signal regression (GSR). This was further supported by diminished detection of subcortical dynamics after GSR, with cortical dynamics predominating. Observed QPPs were both qualitatively and quantitatively determined to be consistent across both anesthesia conditions, with GSR producing the same outcome. Under LA, QPPs were consistently detected at both group and single subject level. Under HA, consistency and pattern occurrence rate decreased, whilst cortical contribution to the patterns diminished. These findings confirm the robustness of QPPs across species and demonstrate a new approach to study mouse LF BOLD spatiotemporal dynamics and mechanisms underlying functional connectivity. The observed impact of GSR on QPPs might help better comprehend its controversial role in conventional resting state studies. Finally, consistent detection of QPPs at single subject level under LA promises a step forward towards more reliable mouse rsfMRI and further confirms the importance of selecting an optimal anesthesia regime. PMID- 29454937 TI - Frequency Modulation of Transcriptional Bursting Enables Sensitive and Rapid Gene Regulation. AB - Gene regulation is a complex non-equilibrium process. Here, we show that quantitating the temporal regulation of key gene states (transcriptionally inactive, active, and refractory) provides a parsimonious framework for analyzing gene regulation. Our theory makes two non-intuitive predictions. First, for transcription factors (TFs) that regulate transcription burst frequency, as opposed to amplitude or duration, weak TF binding is sufficient to elicit strong transcriptional responses. Second, refractoriness of a gene after a transcription burst enables rapid responses to stimuli. We validate both predictions experimentally by exploiting the natural, optogenetic-like responsiveness of the Neurospora GATA-type TF White Collar Complex (WCC) to blue light. Further, we demonstrate that differential regulation of WCC target genes is caused by different gene activation rates, not different TF occupancy, and that these rates are tuned by both the core promoter and the distance between TF-binding site and core promoter. In total, our work demonstrates the relevance of a kinetic, non equilibrium framework for understanding transcriptional regulation. PMID- 29454936 TI - Molecular Time Sharing through Dynamic Pulsing in Single Cells. AB - In cells, specific regulators often compete for limited amounts of a core enzymatic resource. It is typically assumed that competition leads to partitioning of core enzyme molecules among regulators at constant levels. Alternatively, however, different regulatory species could time share, or take turns utilizing, the core resource. Using quantitative time-lapse microscopy, we analyzed sigma factor activity dynamics, and their competition for RNA polymerase, in individual Bacillus subtilis cells under energy stress. Multiple alternative sigma factors were activated in ~1-hr pulses in stochastic and repetitive fashion. Pairwise analysis revealed that two sigma factors rarely pulse simultaneously and that some pairs are anti-correlated, indicating that RNAP utilization alternates among different sigma factors. Mathematical modeling revealed how stochastic time-sharing dynamics can emerge from pulse-generating sigma factor regulatory circuits actively competing for RNAP. Time sharing provides a mechanism for cells to dynamically control the distribution of cell states within a population. Since core molecular components are limiting in many other systems, time sharing may represent a general mode of regulation. PMID- 29454938 TI - Rare Cell Detection by Single-Cell RNA Sequencing as Guided by Single-Molecule RNA FISH. AB - Although single-cell RNA sequencing can reliably detect large-scale transcriptional programs, it is unclear whether it accurately captures the behavior of individual genes, especially those that express only in rare cells. Here, we use single-molecule RNA fluorescence in situ hybridization as a gold standard to assess trade-offs in single-cell RNA-sequencing data for detecting rare cell expression variability. We quantified the gene expression distribution for 26 genes that range from ubiquitous to rarely expressed and found that the correspondence between estimates across platforms improved with both transcriptome coverage and increased number of cells analyzed. Further, by characterizing the trade-off between transcriptome coverage and number of cells analyzed, we show that when the number of genes required to answer a given biological question is small, then greater transcriptome coverage is more important than analyzing large numbers of cells. More generally, our report provides guidelines for selecting quality thresholds for single-cell RNA sequencing experiments aimed at rare cell analyses. PMID- 29454940 TI - Perceptual load is not always a crucial determinant of early versus late selection. AB - The perceptual load hypothesis posits that early and late selection occurs under conditions of high and low perceptual load, respectively. Recent work, however, suggests that the absence of a congruency effect in high-load trials - the behavioral signature of early selection in studies of perceptual load - may not provide an exhaustive index of failing to identify task-irrelevant distractors. Prior research also suggests that the congruency sequence effect (CSE) - a modulation of the congruency effect after incongruent relative to congruent trials - provides complementary information about whether participants identify distractors. We therefore conducted a novel test of the perceptual load hypothesis that employed both the congruency effect and the CSE as measures of distractor identification. Experiment 1 revealed that distractors were identified not only in low-load trials but also in high-load trials wherein there was no overall congruency effect. Experiment 2 further revealed which task parameters allowed us to observe such "hidden" distractor identification. These findings suggest that perceptual load is not always a crucial determinant of early versus late selection. PMID- 29454939 TI - Comparative Analysis of Immune Cells Reveals a Conserved Regulatory Lexicon. AB - Most well-characterized enhancers are deeply conserved. In contrast, genome-wide comparative studies of steady-state systems showed that only a small fraction of active enhancers are conserved. To better understand conservation of enhancer activity, we used a comparative genomics approach that integrates temporal expression and epigenetic profiles in an innate immune system. We found that gene expression programs diverge among mildly induced genes, while being highly conserved for strongly induced genes. The fraction of conserved enhancers varies greatly across gene expression programs, with induced genes and early-response genes, in particular, being regulated by a higher fraction of conserved enhancers. Clustering of conserved accessible DNA sequences within enhancers resulted in over 60 sequence motifs including motifs for known factors, as well as many with unknown function. We further show that the number of instances of these motifs is a strong predictor of the responsiveness of a gene to pathogen detection. PMID- 29454941 TI - Characterization and electrochemical response of DNA functionalized 2nm gold nanoparticles confined in a nanochannel array. AB - Polyvalent gold nanoparticle oligonucleotide conjugates are subject of intense research. Even though 2nm diameter AuNPs have been previously modified with DNA, little is known about their structure and electrochemical behavior. In this work, we examine the influence of different surface modification strategies on the interplay between the meso-organization and the molecular recognition properties of a 27-mer DNA strand. This DNA strand is functionalized with different sulfur containing moieties and immobilized on 2nm gold nanoparticles confined on a nanoporous alumina, working the whole system as an electrode array. Surface coverages were determined by EXAFS and the performance as recognition elements for impedance-based sensors is evaluated. Our results prove that low DNA coverages on the confined nanoparticles prompt to a more sensitive response, showing the relevance in avoiding the DNA strand overcrowding. The system was able to determine a concentration as low as 100pM of the complementary strand, thus introducing the foundations for the construction of label-free genosensors at the nanometer scale. PMID- 29454942 TI - Cloning, molecular modeling and characterization of acidic cellulase from buffalo rumen and its applicability in saccharification of lignocellulosic biomass. AB - Cellulase hydrolyses the cellulose by cleaving the beta-1,4-linkages to produce mono-, oligo- and shorter polysaccharide units. These enzymes have applications in various industries such as pulp and paper, laundry, food and feed, textile, brewing industry and in biofuel production. In the present study we have cloned acid-cellulase gene (Cel-1) from the fosmid library of buffalo rumen metagenomic DNA and functionally expressed it in Escherichia coli. The ORF encoding cellulase consisted of 1176-bp, corresponding to protein of 391 amino acid and has catalytic domain belonging to glycosyl hydrolase family 5. The purified protein has a molecular weight of 43-kDa on SDS-PAGE and its expression was confirmed by western blotting. The tertiary structure of the cellulase (Cel-1) showed a classical (alpha/beta) TIM-like barrel motif. Model surface charge of Cel-1 predicted that surface near active site was mostly negative which might be responsible for the stability of enzyme at lower pH. The pH and temperature for maximum enzyme activity were 4.5 and 45 degrees C respectively. Various metal ions enhanced the enzyme activity and in presence of Mn+2 activity was significantly increased. Cel-1 hydrolyzed pre-treated wheat straw and released reducing sugars (62.60%). These desirable properties of Cel-1 make it attractive for the bioconversion of biomass. PMID- 29454943 TI - Research of a new metal chelating carrier preparation and papain immobilization. AB - A new type of magnetic metal chelating carrier (PCMM-IDA-Cu2+) was prepared for the immobilization of papain, using chitosan as raw material, nano Fe3O4 as magnetic material, SiO2 as porogen, iminodiacetic acid (IDA) as a chelating ligand, and binding with transition metal ion (Cu2+). The resulting products were well characterized by optical microscopy, scanning electron microscopy (SEM), vibrating sample magnetometer (VSM), Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA). The BBD (Box-Behnken Design) of RSM (Response Surface Methodology) was applied to analyze the optimum enzyme immobilization conditions. The results showed that the enzyme immobilization capacity was 94.18mg/g of PCMM-IDA-Cu2+, with 7.976U/mg of relative immobilized enzyme activity under the optimum conditions (pH6.73, 1.56mg enzyme/15.0mg carrier, 30.9 degrees C), and the recovery of enzyme activity was reached 87.21%. Compared with the free papain, the immobilized papain displayed enhanced enzyme activity, superior enzymatic properties, good operational stability and reusability. It is worth mentioning that the novel carriers exhibited selectively biological adsorption capacity, and this technique is an alternative method for the immobilization of enzyme, making the process more efficient and economic. PMID- 29454944 TI - Preparation, characterization and bioactivities of Athelia rolfsii exopolysaccharide-zinc complex (AEPS-zinc). AB - A new Athelia rolfsii exopolysaccharides (AEPS) were purified by Sephacryl S-300 and S-200. The physicochemical characteristics of AEPS fractions were assayed by HPGPC and GC methods. The structures of AEPS and AEPS-zinc complex were characterized by SEM, FTIR and NMR. Moreover, the bioactivities of complex were also evaluated by experiments in vitro and in vivo. AEPSI consisted of glucose, galacturonic acid, talose, galactose, mannose and xylose, the relative contents of them were 24.74, 19.60, 33.65, 8.77, 7.97 and 5.28%, respectively. AEPSII consisted of glucose, inositol, galacturonic acid, ribitol, gluconic acid, talose and xylose, whose relative contents were 36.06, 21.21, 12.78, 11.07, 6.58, 5.45 and 6.82%, respectively. The Mw and Mn of AEPSI were 6.1324*104 and 1.4218*104Da, those of AEPSII were 517 and 248Da. SEM observations showed that microstructures of AEPS and AEPS-zinc complex were obviously different both in size and shape. FTIR and NMR analysis indicated that AEPS might chelate with zinc ion through hydroxy and carboxy group. In vitro experiments showed that AEPS-zinc complex had a good bioavailability, in vivo experiments showed that it had good effect on improving zinc deficiency and antioxidant activities, which suggested that it could be used as zinc supplementation with high antioxidant activities.

AB - Dextran based bionanocomposite membranes encapsulating clove oil (CO) and sandalwood oil (SO) that are capable of preventing infection due to their inherent virtue of antibacterial activity and modifying the wound healing cascade for accelerated scar free healing, were developed. A facile solvent casting technique was used to fabricate dextran/nanosoy/glycerol/chitosan (DNG/Ch) nanocomposite membranes followed by subsequent addition of CO and SO to obtain DNG/Ch/CO and DNG/Ch/SO herbal nanodressings. Dressings exhibited >98% antibacterial activity against both Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) at extremely low loadings of 5% and 10% for CO and SO, respectively. This encapsulation strategy allowed controlled diffusion of EO over a period of 72h which was measured in terms of drug efficacy using bacterial reduction count test and serial plate transfer disk diffusion test (SPTDDT). Swelling behavior and mechanical properties were also examined. Bacterial adherence study was performed to demonstrate the efficiency of dressings for arresting microbial invasion. In vivo wound healing studies were conducted using male swiss albino mice of BALB/c strain and DNG/Ch/CO dressings exhibited complete healing within 14days with remarkable efficacy in scar prevention. Histological analysis revealed that CO and SO treatment led to deposition of ordered collagen along with fibroblast migration. PMID- 29454946 TI - Changes of physical properties of PLA-based blends during early stage of biodegradation in compost. AB - Three biodegradable plastics materials, namely pure poly(l-lactide) (PLA), PLA with plasticizer triacetine (TAC) and the mixture PLA/polyhydroxybutyrate (PHB) and TAC were investigated concerning changes of physical properties due to biodegradation in compost at 58 degrees C up to 16days. With rising time of degradation in compost, both number and weight molecular masses were decreasing progressively, but only marginal change of the polydispersity index was observed which indicates that biodegradation is not random process. FTIR spectroscopy revealed that in spite of the extensive decrease of molecular weight, no substantial change in chemical composition was found. The most significant modification of the spectra consisted in an appearing of the broad band in region 3100-3300cm-1, which was assigned to a formation of biofilm on the sample surfaces. This effect appeared for all three materials, however, it was much more pronounced for samples containing also triacetine. Measurement of changes in crystalline portion confirmed that amorphous phase degrades substantially faster compared to crystalline part. The plasticizer triacetine is disappearing also rather fast from the sample resulting besides other effect also in a temporary increase of Tg, which at the beginning grows almost to the value typical for PLA without plasticizer but later the Tg is decreasing due to substantial changes in molecular weight. Generally during composting, the samples keep shape for up to 8days, after that time the material disintegrates to rough powder. PMID- 29454947 TI - Guide to electrospinning denatured whole chain collagen from hoki fish using benign solvents. AB - Tissue engineering requires the design and manufacture of biomimetic scaffolds. Collagen-derived nanofibrous scaffolds have been intensively studied because collagen, in the form of fibrils, is one of the main components of the extra cellular matrix (ECM). Several collagen materials have been used in electrospinning studies including mammalian extracted Type I collagen and gelatin formulations. Denatured whole chain collagen (DWCC) can be prepared by heat denaturing acid-soluble collagen extracted from cold-water fish skin. This product provides a consistent source of collagen with a controlled molecular weight profile and intact alpha chains including telopeptides. In this work, we studied DWCC-water-acid systems in order to determine the effect of solution composition on nanofibre morphology. Whereas measurement of the classical physical properties of concentrated solutions failed to predict and only partially explained the electrospinning behavior of collagen derived polymers, hydrodynamic properties provided insight. All the samples are presented in ternary diagrams to map the electrospinnability of the systems. These "electrospinning maps" provide an informative resource to electrospinning collagen-derived product for biomedical or commercial applications and a practical alternative to complicated models developed for synthetic polymers.

The mechanism by which sulfhydryl reductant compounds enhances the activity of P. vannamei protease still remains unclear. In this study, it was discovered that thiol-reactive compounds increase P. vannamei protease activity by a factor of about 4 with increasing Vmax and decreasing Km parameters. Moreover, the reaction is an SN2 type that does not require the initial binding of the thiol group of these compounds to the enzyme. Additionally, k2 increased appreciably with increasing concentration of sulfhydryl reductant compounds. The linearity of this plot indicates that k1 is unaffected by the addition of thiol compounds. Hence, the observed effect of thiol compounds on Km seems to be due to an increase in k2. These results suggest that the activation mechanism of P. vannamei protease almost certainly takes place by an SN2 reaction mechanism.

AB - Iron-carboxylate (MIL-100(Fe)) and HKUST-1 (Cu3(BTC)2, BTC=1,3,5 benzenetricarboxylic acid) as nanoporous metal organic framework supports were compared for immobilization of porcine pancreatic lipase (PPL). These immobilizations improved thermal, pH and operational stability of PPL compared to the soluble enzyme. Stability of MIL-100(Fe) was better than HKUST-1 as support. MIL-100(Fe) encapsulated Keggin phosphotungstic acid H3PW12O40 (PW) (PW@MIL 100(Fe)) was synthesized to develop novel enzyme immobilized system and characterized by Fourier transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FE-SEM), Brunauer-Emmett-Teller (BET), X-ray diffraction (XRD) and Barrett Joyner Halenda (BJH) analysis. Relative activity for immobilized lipase on PW@MIL-100(Fe) was more than MIL-100(Fe) in pH range of 3-9. At the elevated temperature of 70 degrees C, the PW@MIL-100(Fe) was the most stable one. PW@MIL-100(Fe)/PPL substrate exhibited the higher stability at 4 degrees C and 25 degrees C, along with other supports. Moreover, PW@MIL-100(Fe) was chosen as the best support for immobilization of PPL and was also applied for the synthesis of benzyl cinnamate by enzymatic esterification of cinnamic acid. The immobilized enzyme retained 90.4% of its initial activity during synthesis of benzyl cinnamate after 5 successive catalytic rounds and reached 80.0% yield after 8 reuses. PMID- 29454951 TI - The role of sucrose concentration in self-assembly kinetics of high methoxyl pectin. AB - Several natural and synthetic polysaccharides are able to form, under appropriate conditions, supramolecular structures, typically physical hydrogels, and, together with their biocompatibility, this explains their wide use in food, pharmaceutical and biomedical sectors. In the case of high methoxyl pectins (HMP) the gel formation is promoted by the presence of cosolutes (sugars or polyols) and low pH. The present investigation mainly regards the structuring kinetics of aqueous HMP solutions at acid pH (3.1) with the same pectin concentration (0.2% w/w) and different sucrose concentrations (from 56 to 65% w/w). Preliminary viscosity tests were performed to individuate the threshold of the sol region. A sequence of consecutive frequency sweeps was applied to each sample immediately after its preparation. The time evolution of the linear viscoelastic behavior is described by the sigmoidal profiles of both moduli at each applied frequency and more thoroughly defined through the change of the mechanical spectrum, i.e. the variation of the parameters of the generalized Maxwell model or the Friedrich Braun model which are both suitable to provide a satisfactory data fitting. In particular, the equilibrium modulus Ge offers a significant description of the gelation kinetics and its sucrose dependence. PMID- 29454950 TI - Producing novel edible films from semi refined carrageenan (SRC) and ulvan polysaccharides for potential food applications. AB - Edible films were developed from seaweed polysaccharides (Kappaphycus alvarezii and Ulva fasciata). The total extracted yield of semi refined carrageenan (SRC) and ulvan polysaccharide was 31.55%, and 28.86%, with total carbohydrate being 78.08% and 82.43% in SRC and ulvan polysaccharides. Results of viscometric studies revealed molecular weight to be 210kDa and 72kDa for SRC and ulvan polysaccharides. Proton NMR studies showed presence of anhydro-d-galactopyranose and glucosidic linkages in SRC, while ulvan polysaccharide had rhamnose-3 sulfate, glucosyl and beta-d-glucuronic acid. Three different films developed from SRC and ulvan polysaccharides [SRC, ulvan polysaccharide and combination of SRC and ulvan polysaccharide films] with glycerol. FT-IR spectra confirmed functional group of all the edible films which corresponds with NMR results. Water vapor permeability of films indicated a range of 7.82 to 9.96*10-8gm-1s-1Pa 1 with high tensile strength varying between 36.78 and 49.12MPa. Results on antioxidant activity indicated a strong hydroxyl radical scavenging activity detected in ulvan polysaccharide based film, while metal ion chelating activity was higher in films with a combination of SRC and ulvan polysaccharides. Further, low molecular weight films had better antioxidant activity, while high molecular weight films possessed good mechanical properties. PMID- 29454952 TI - Probing the interaction of the phytochemical 6-gingerol from the spice ginger with DNA. AB - 6-Gingerol [5-hydroxy-1-(4-hydroxy-3-methoxyphenyl) decan-3-one], the bio-active ingredient of the popular Indian spice ginger (Zingiber officinale Roscoe), is well-known for its pharmacological and physiological actions. The potent antioxidant, antiemetic, antiulcer, antimicrobial, analgesic, hypoglycemic, antihypertensive, antihyperlipidemic, immunostimulant, anti-inflammatory, cardiotonic, and cancer prevention activities of 6-Gingerol has been investigated and explored. 6-Gingerol is a good candidate for the treatment of various cancers including prostrate, pancreatic, breast, skin, gastrointestinal, pulmonary, and renal cancer. In this study we report for the first time the molecular recognition of 6-Gingerol with calf thymus DNA (ctDNA) through experimental and molecular modeling techniques confirming a minor groove binding mode of 6 Gingerol with ctDNA. Fluorescence and UV-vis spectroscopic studies confirm the complex formation of 6-gingerol with ctDNA. The energetics and thermodynamics of the interaction of 6-Gingerol with ctDNA was explored by Isothermal Titration Calorimetry (ITC) and Differential Scanning Calorimetry (DSC). The ctDNA helix melting upon 6-Gingerol binding was examined by melting temperature Tm analysis. Further the electrophoretic mobility shift assay confirms a possible groove binding of 6-Gingerol with ctDNA. Molecular docking and Molecular dynamics (MD) studies provide a detailed understanding on the interaction of 6-Gingerol binding in the minor groove of DNA which supports experimental results. PMID- 29454953 TI - Non-active site mutation (Q123A) in New Delhi metallo-beta-lactamase (NDM-1) enhanced its enzyme activity. AB - New Delhi metallo beta-lactamase-1 is one of the carbapenemases, causing hydrolysis of almost all beta-lactamase antibiotics. Seventeen different NDM variants have been reported so far, they varied in their sequences either by single or multiple amino acid substitutions. Hence, it is important to understand its structural and functional relation. In the earlier studies role of active site residues has been studied but non-active site residues has not studied in detail. Therefore, we have initiated to further comprehend its structure and function relation by mutating some of its non-active site residues. A laboratory mutant of NDM-1 was generated by PCR-based site-directed mutagenesis, replacing Q to A at 123 position. The MICs of imipenem and meropenem for NDM-1Q123A were found increased by 2 fold as compare to wild type and so the hydrolytic activity was enhanced (Kcat/Km) as compared to NDM-1 wild type. GOLD fitness scores were also found in favour of kinetics data. Secondary structure for alpha-helical content was determined by Far-UV circular dichroism (CD), which showed significant conformational changes. We conclude a noteworthy role of non-active site amino acid residues in the catalytic activity of NDM-1. This study also provides an insight of emergence of new variants through natural evolution. PMID- 29454954 TI - Preparation and characterization of C-phycocyanin peptide grafted N-succinyl chitosan by enzyme method. AB - C-phycocyanin peptide (CPC) grafted N-succinyl chitosan (NSC) was prepared via the catalysis of Microbial transglutaminase (MTGase). The single factor experiment displayed that the degree of substitution (DS) of N-succinyl chitosan C-phycocyanin peptide (NSC-CPC) depended on the reaction time, the reaction temperature and the reaction pH value. The CS, synthesized NSC and NSC-CPC were characterized by Fourier transform infrared spectroscopy (FT-IR). NSC-CPC showed excellent moisture absorption and retention ability. In vitro antioxidant activity assays demonstrated that, with the DS and concentration increasing of NSC-CPC, the scavenging activity of 1,1-Diphenyl-2-pic-rylhydrazyl (DPPH) radical and hydroxyl radical increased. The methylthiazol tetrazolium (MTT) essay demonstrated that NSC-CPC inhibited Hela cells while promoted the proliferation of L929 mouse fibroblasts. In conclusion, these results suggested the potential application of NSC-CPC in pharmaceutical and biomedical fields. PMID- 29454955 TI - Physicochemical properties of starch adhesives enhanced by esterification modification with dodecenyl succinic anhydride. AB - Starch-based adhesives were prepared by esterification modification with dodecenyl succinic anhydride (DDSA) and polyaryl polymethylene isocyanate (PAPI) as a crosslinking agent. DDSA modified starch (DMS) adhesives could significantly enhance the viscosity and adhesion strength of starch adhesives, making it beneficial to be applied in the field of plywood industry. This paper investigated the physicochemical properties of starch modified by dodecenyl succinic anhydride. Solid content, viscosity, adhesion, structural change and morphological features were characterized in detail. Viscosity and solid content of the modified starch (MF) adhesives was improved remarkably when DDSA was introduced. Three-ply plywood was fabricated with DMS adhesives, and its wet shear strength was measured. The results showed that the water resistance of the adhesive with 6wt% DDSA improved by 72.4% compared to that without DDSA. The wet shear strength plywood bonded by the adhesive reached 1MPa and could meet the requirement set by the China National Standard. Incorporating DDSA into the starch adhesive formed a dense crosslinking structure due to chemical reactions between DDSA and active groups on the starch molecules and thus improve the water resistance of the cured adhesives. The introduction of DDSA improving the viscosity and solid content remarkably, which increased the amount of the adhesive that penetrated the wood surface and formed more interlocks. Using DDSA promoted a smooth and homogeneous fracture surface of cured adhesive, which effectively prevented water intrusion and improved water resistance. The modified adhesive proved practical as a plywood adhesive for industrial application. PMID- 29454956 TI - De novo transcriptome assembly and analysis of differential gene expression following peptidoglycan (PGN) challenge in Antheraea pernyi. AB - Antheraea pernyi is not only an important economic insect, it is increasingly employed as a model organism due to a variety of advantages, including ease of rearing and experimental manipulation compared with other Lepidoptera. Peptidoglycan (PGN) is a major component of the bacterial cell wall, and interactions between PGN and A. pernyi cause a series of physiological changes in the insect. In the present study, we constructed cDNA libraries from a A. pernyi PGN-infected group and a control group stimulated with phosphate-buffered saline (PBS). The transcriptome was de novo assembled using the Trinity platform, and 1698 differentially expressed genes (DEGs) were identified, comprising 894 up regulated and 804 down-regulated genes. To further investigate immune-related DEGs, gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment were performed. GO analysis identified major immune-related GO terms and KEGG enrichment indicated gene responses to three pathways related to the insect immune system. Several homologous genes related to the immune response of the A. pernyi fat body post-PGN infection were identified and categorised. Taken together, the results provide insight into the complex molecular mechanisms of the responses to bacterial infection at the transcriptional level. PMID- 29454958 TI - Clinical Features and Surgical Management of Cerebellopontine Angle Cholesteatoma That Presented as Trigeminal Neuralgia. AB - BACKGROUND: It is difficult to differentiate patients with cerebellopontine angle (CPA) cholesteatoma and patients with primary trigeminal neuralgia just according to early symptoms. We aimed to explore the clinical characteristics, early diagnosis, and microneurosurgical techniques for CPA cholesteatoma that presented as trigeminal neuralgia. METHODS: The data of 26 patients who complained trigeminal neuralgia with CPA cholesteatoma between January 2009 and December 2015 were collected and studied retrospectively, they were diagnosed by magnetic resonance imaging preoperatively and confirmed by pathology postoperatively. All the tumors were resected through a retrosigmoidal approach. In 26 cases, 14 patients who underwent cholesteatoma resection and microvascular decompression were assigned to group A and 12 patients who underwent only cholesteatoma resection were assigned to group B. The clinical features and surgical results between groups A and B were compared. The complications and surgical results were followed up, and surgical techniques were summarized. RESULTS: All patients presented as trigeminal neuralgia at the same side of the cholesteatoma. There was no statistical difference between the 2 groups in clinical features and surgical results between groups A and B. All patients with cholesteatoma showed clear and significant imaging characteristics. The tumors were totally removed in 18 patients and subtotally removed in 8 patients. Pain relief was satisfactory in all patients. Surgical complications included transient aseptic meningitis in 2 patients, facial numbness in 2 patients, mild tinnitus in 2 patients, mild and facial weakness in 1 patient. No death, hematoma, or acute hydrocephalus were reported in this series. During the follow-up of 12-80 months, no patient experienced recurrence of pain or tumor. CONCLUSIONS: Cholesteatoma of the cerebellopontine angle often presented as trigeminal neuralgia. Magnetic resonance imaging is helpful for early diagnosis according to its distinct signal. Surgical treatment is often the first choice, the neuralgia relief was satisfactory after operation. Microvascular decompression is recommended simultaneously if some offending vessels were founded during the surgical resection of the tumor. PMID- 29454957 TI - Mixed selectivity encoding and action selection in the prefrontal cortex during threat assessment. AB - The medial prefrontal cortex (mPFC) regulates expression of emotional behavior. The mPFC combines multivariate information from its inputs, and depending on the imminence of threat, activates downstream networks that either increase or decrease the expression of anxiety-related motor behavior and autonomic activation. Here, we selectively highlight how subcortical input to the mPFC from two example structures, the amygdala and ventral hippocampus, help shape mixed selectivity encoding and action selection during emotional processing. We outline a model where prefrontal subregions modulate behavior along orthogonal motor dimensions, and exhibit connectivity that selects for expression of one behavioral strategy while inhibiting the other. PMID- 29454959 TI - Exophytic Cerebral Hemispheric Low-Grade Glioma: Unusual Growth Pattern of Common Central Nervous System Tumor. AB - BACKGROUND: Exophytic growth (EG), wherein the tumor mass grows beyond the neuraxial boundary formed by pia mater, remains a rare pattern of glioma growth. It has been described in gliomas at several locations like the brainstem, cerebellum, suprasellar area, spinal cord, and insula. However, EG in hemispheric grade 2 astrocytomas, particularly affecting the convexity subarachnoid space, as against the more spacious basal subarachnoid space, is exceedingly rare. To the best of our knowledge, there is only 1 such case reported in the English literature. Due to the extreme rarity, little is known about these tumors, particularly the mechanisms underlying the EG and their possible clinical implications. CASE DESCRIPTION: A 32-year-old woman presented with partial motor seizures without any neurologic signs. On magnetic resonance imaging of the head, a nonenhancing, T2-hyperintense, right frontal lobe lesion was noted. The majority of the lesion was occupying the adjacent subdural space while still remaining in continuity with the intra-axial globular component. During surgery, the exophytic nature of the lesion was confirmed. We performed maximal resection of the exophytic portion with subtotal excision of the intra-axial component. She recovered uneventfully after surgery and subsequently received external beam radiotherapy for the residual tumor. CONCLUSION: Although extremely rare, cerebral hemispheric grade 2 astrocytomas may have an EG pattern. The exact mechanisms underlying this are not clearly known. More such cases need to be reported so that we can decipher the true nature of these tumors. PMID- 29454960 TI - Case of Subarachnoid Hemorrhage from Ruptured Oncotic Fusiform Aneurysms from Choriocarcinoma Metastasis Treated with Aneurysmectomy and Vessel Reconstruction. AB - BACKGROUND: Oncotic aneurysm is a rare condition with a high mortality rate. Because no consensus has been reached regarding therapeutic strategy for ruptured oncotic aneurysm, treatment remains challenging. CASE DESCRIPTION: A 35-year-old woman developed sudden onset of severe headache. Computed tomography showed subarachnoid hemorrhage and cerebral angiography revealed 2 fusiform aneurysms in the distal portion of the left middle cerebral artery. Aneurysmectomy with vessel reconstruction using a superficial temporal artery graft was performed to maintain blood flow to the distal middle cerebral artery. Pathologic examination of the aneurysm and wall of the resected recipient middle cerebral artery showed infiltrating trophoblasts. Immunostaining for human chorionic gonadotropin was positive in the aneurysm specimen. On the basis of an elevated concentration of serum human chorionic gonadotropin, choriocarcinoma with ruptured intracranial oncotic aneurysms was diagnosed. After further systemic examination for carcinoma, chemotherapy was initiated. CONCLUSIONS: Aneurysmectomy, resection of the parent artery with irregular walls and reconstruction to the distal recipient artery with normal intima should be considered to secure patency of the anastomosis and prevent the recurrence of oncotic aneurysm. Subsequent chemotherapy is essential to prevent carcinomatous meningitis and disease progression. PMID- 29454961 TI - First-line anti-tuberculosis drugs induce hepatotoxicity: A novel mechanism based on a urinary metabolomics platform. AB - Tuberculosis (TB) has become a global public health and social threat. As clinical first-line drugs, rifampicin and isoniazid used in combination with pyrazinamide and ethambutol (the HRZE regimen) usually induce hepatotoxicity. However, the mechanisms underlying this phenomenon remain unclear, and studying the metabolic impact of co-treating TB patients with the HRZE regimen can provide new hepatotoxicity evidence. In this study, urine metabolites from TB patients were profiled using a high-resolution ultra-performance liquid chromatography mass spectrometry (UPLC-MS) platform. The tricarboxylic acid circulation, arginine and proline metabolism and purine metabolic pathways were found to be affected by anti-TB drugs. The levels of pyroglutamate, isocitrate, citrate, and xanthine were significantly decreased after the administration of HRZE. The above mentioned pathways were also different between drug-induced liver injury (DILI) and non-DILI patients. Urate and cis-4-octenedioic acid levels in the DILI group were significantly increased compared to those in the non-DILI group, while the cis-aconitate and hypoxanthine levels were significantly decreased. These results highlight that superoxide generation can aggravate the hepatotoxic effects of the HRZE regimen. In addition, our metabolomic approach had the ability to predict hepatotoxicity for clinical applications. PMID- 29454962 TI - The high bone mass phenotype of Lrp5-mutant mice is not affected by megakaryocyte depletion. AB - Bone remodeling is a continuously ongoing process mediated by bone-resorbing osteoclasts and bone-forming osteoblasts. One key regulator of bone formation is the putative Wnt co-receptor Lrp5, where activating mutations in the extracellular domain cause increased bone formation in mice and humans. We have previously reported that megakaryocyte numbers are increased the bone marrow of mice carrying a high bone mass mutation (HBM) of Lrp5 (Lrp5G170V). Since megakaryocytes can promote bone formation, we addressed the question, if the bone remodeling phenotype of Lrp5G170V mice is affected by megakaryocyte depletion. For that purpose we took advantage of a mouse model carrying a mutation of the Mpl gene, encoding the thrombopoietin receptor. These mice (Mplhlb219) were crossed with Lrp5G170V mice to generate animals carrying both mutations in a homozygous state. Using MUCT, undecalcified histology and bone-specific histomorphometry of 12 weeks old littermates we observed that megakaryocyte number was remarkably decreased in Mplhlb219/Lrp5G170V mice, yet the high bone mass phenotype of Lrp5G170V mice was not significantly affected by the homozygous Mpl mutation. Finally, when we analyzed 24 weeks old wildtype and Mplhlb219 mice we did not observe a statistically significant alteration of bone remodeling in the latter ones. Taken together, our results demonstrate that an increased number of bone marrow megakaryocytes does not contribute to the increased bone formation caused by Lrp5 activation. PMID- 29454963 TI - Adenosine receptors enhance the ATP-induced odontoblastic differentiation of human dental pulp cells. AB - Purinergic signaling regulates various biological processes through the activation of adenosine receptors (ARs) and P2 receptors. ATP induces the odontoblastic differentiation of human dental pulp cells (HDPCs) via P2 receptors. However, there is no information available about the roles of ARs in HDPC odontoblastic differentiation induced by ATP. Here, we found that HDPCs treated with ATP showed higher activity of ADORA1 (A1R), ADORA2B (A2BR), and ADORA3 (A3R). Inhibition of A1R and A2BR attenuated ATP-induced odontoblastic differentiation of HDPCs, whereas activation of the two receptors enhanced the odontoblastic differentiation induced by ATP. However, activation of ARs by adenosine did not induce the odontoblastic differentiation of HDPCs independently without induction of ATP. Our study indicates a positive role for ARs in ATP induced odontoblastic differentiation of HDPCs, and demonstrates that ATP-induced odontoblastic differentiation of HDPCs may be due to the combined administration of ARs and P2 receptors. This study provides new insights into the molecular mechanisms of pulpal injury repair induced by ATP. PMID- 29454964 TI - NEK3-mediated SNAP29 phosphorylation modulates its membrane association and SNARE fusion dependent processes. AB - Intracellular membrane fusion depends on the presence of specific mediators, the vesicle (v-) and the target (t-) SNAREs (Soluble N-ethylmaleimide-sensitive factor, NSF, attachment protein SNAP receptors), whose interaction brings apposing membranes to close proximity and initiates their fusion. SNAP29 (synaptosomal-associated protein 29), a t-SNARE protein, is involved in multiple fusion events during intracellular transport and affects structure of organelles such as the Golgi apparatus and focal adhesions. Mutations in SNAP29 gene result in CEDNIK (Cerebral dysgenesis, neuropathy, ichthyosis and palmoplantar keratoderma) syndrome. In the present study, we show that NEK3 (NIMA-never in mitosis gene A-related kinase 3)-mediated serine 105 (S105) phosphorylation of SNAP29 directs its membrane association, without which cells present defective focal adhesion formation, impaired Golgi structure and attenuated cellular recycling. In contrast to a phosphorylation-defective serine 105 to alanine (S105A) mutant, wildtype SNAP29, partially rescued the abnormal morphology of a CEDNIK patient derived fibroblasts. Our results highlight the importance of NEK3 mediated S105 phosphorylation of SNAP29 for its membrane localization and for membrane fusion dependent processes. PMID- 29454965 TI - Detection of synchronized burst firing in cultured human induced pluripotent stem cell-derived neurons using a 4-step method. AB - Human induced pluripotent stem cell-derived neurons are promising for use in toxicity evaluations in nonclinical studies. The multi-electrode array (MEA) assay is used in such evaluation systems because it can measure the electrophysiological function of a neural network noninvasively and with high throughput. Synchronized burst firing (SBF) is the main analytic parameter of pharmacological effects in MEA data, but an accurate method for detecting SBFs has not been established. In this study, we present a 4-step method that accurately detects a target SBF confirmed by the researcher's interpretation of a raster plot. This method calculates one set parameter per step, in the following order: the inter-spike interval (ISI), the number of spikes in an SBF, the inter SBF interval, and the number of spikes in an SBF again. We found that the 4-step method is advantageous over the conventional method because it determines the preferable duration of an SBF, accurately distinguishes continuous SBFs, detects weak SBFs, and avoids false detection of SBFs. We found also that pharmacological evaluations involving SBF analysis may differ depending on whether the 4-step or conventional threshold method is used. This 4-step method may contribute to improving the accuracy of drug toxicity and efficacy evaluations using human induced pluripotent stem cell-derived neurons. PMID- 29454966 TI - Effects of PQ's cytotoxicity on secretory vesicles in astroglia: Expression alternation of secretogranin II and its potential interaction with intracellular factors. AB - It has been extensively characterized that paraquat (PQ) selectively targets to the substantia nigra and exerts neurotoxic actions on dopaminergic neurons. However, a little knowledge is available about astroglia in PQ exposure, especially its complex secretory machinery. To explore this point, we built up a PQ-induced model in cultural U118 astrocyte. Since the granin family is considered as a master regulator of cargo sorting and large dense core vesicles (LDCVs) biogenesis in the regulated secretory pathway of nervous and neuroendocrine cells, the current study focused on one member, secretogranin II (SCG2) and investigated its alternation and potential relationship with other astrocyte-derived factors under PQ insult. We found that PQ upregulated SCG2 expression on both RNA and protein levels and stimulated the mRNA expression of neurotrophic factors, cytokines and glutamine synthetase (GS) simultaneously. RNAi knockdown of SCG2 did not rescue the cell cycle arrest induced by PQ but affected expressions of IL-6 and GS on mRNA and protein levels. Further studies on subcellular location showed that SCG2-positive secretory granules were partially colocalized with IL-6 but not GS in PQ exposure astrocyte. Taken together, our findings indicate that the expression alternation of SCG2 under astroglial activation by PQ may be necessary compensation for cargo sorting and LDCV biogenesis. The involvement of the IL-6 and GS suggests that the SCG2 may potentially regulate inflammatory factors and excitatory neurotransmitter to the cytotoxicity of PQ on astroglia. PMID- 29454967 TI - SARM1 deletion restrains NAFLD induced by high fat diet (HFD) through reducing inflammation, oxidative stress and lipid accumulation. AB - SARM1 (Sterile alpha and armadillo motif-containing protein 1) is the recently identified TIR domain-containing cytosolic protein, which is involved in toll like receptors (TLRs) signaling transduction. In the present study, the role of SARM1 in high fat diet (HFD)-induced non-alcoholic fatty liver disease (NAFLD) progression was explored. We found that SARM1 was expressed highly in fatty liver. And SARM1-knockout (KO) reduced steatohepatitis and metabolic disorders induced by HFD. SARM1-deletion decreased aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels in HFD-fed mice. Additionally, inflammatory response caused by HFD was alleviated by SARM1-deletion through inactivating TLR4/7/9 and nuclear factor kappa B (NF-kappaB) pathways. Of note, SARM1-deletion also reduced the expressions of inflammation-associated molecules in hypothalamus of HFD-fed mice. Furthermore, HFD administration led to oxidative stress in liver of mice, while being decreased in SARM1-KO mice. Moreover, SARM1-ablation improved lipid dyslipidemia by suppressing the mRNA levels of genes, linked to glycolysis, lipogenesis and transcriptional regulation. Insulin resistance was also attenuated by SARM1-deficiency through enhancing the activation of liver Akt/glycogen synthase kinase-3beta (GSK3beta) and insulin receptor substrate-1 (IRS1)/FOXO1 pathways in HFD-fed mice. Also, SARM1-knockout improved neuropeptide Y (NPY), Pro-Opiomelanocortins (POMC), Agouti-related Protein (AGRP) and Cocaine and-Amphetamine Responsive Transcript 1 (CART1) expressions in hypothalamus of mice after HFD administration. In vitro, we found that the reduction of inflammatory response, oxidative stress and dyslipidemia induced by SARM1 knockout in primary hepatocytes after fructose stimulation was largely attributed to its suppression to TLR4/7/9. Together, the findings demonstrated that SARM1 might be an effective target for developing effective therapeutic strategies against NAFLD. PMID- 29454968 TI - Ess2 bridges transcriptional regulators and spliceosomal complexes via distinct interacting domains. AB - Transcription and pre-mRNA splicing are complex, coupled processes that involve transcriptional co-regulators. Ess2 (also termed Dgcr14) is a nuclear protein that enhances the transcriptional activity of retinoic acid receptor-related orphan receptor gamma/gamma-t (Rorgamma/gammat). Ess2 is also a component of the spliceosomal C complex (containing U2, U5 and U6 snRNAs). However, the domains in Ess2 that function in splicing and transcription have not been identified. To elucidate the roles of Ess2 in splicing and transcription, we performed RNA immunoprecipitation (RIP) assays to detect Ess2-interacting snRNAs. We found that Ess2 associated with U6 snRNA as well as U1 and U4 snRNAs. Experiments using Ess2 deletion mutants showed that a C-terminus deletion mutant of Ess2 (1-399 a. a.) lost its ability to associate with snRNAs, whereas the N-terminus domain of Ess2 (1-200 a. a.) associated with Rorgamma/gammat, but not with snRNAs. Interestingly, experiments using anti-ROR common antibody showed that Rors also associated with U4 and U6 snRNAs. Ess2 knockdown in a T cell hybridoma (68-41 cells) abrogated the interaction between spliceosomes and Rors. An Ess2-dependent association was also found between an lncRNA (Rmrp) and Rors. We thus propose that Ess2 associates with both transcriptional factors and spliceosomal complexes and modulates splicing reactions coupled with transcription factors. PMID- 29454970 TI - Increased cerebrospinal fluid complement C5 levels in major depressive disorder and schizophrenia. AB - Inflammation has been implicated in a variety of psychiatric disorders. We aimed to determine whether levels of complement C5 protein in the cerebrospinal fluid (CSF), which may reflect activation of the complement system in the brain, are altered in patients with major psychiatric disorders. Additionally, we examined possible associations of CSF C5 levels with clinical variables. Subjects comprised 89 patients with major depressive disorder (MDD), 66 patients with bipolar disorder (BPD), 96 patients with schizophrenia, and 117 healthy controls, matched for age, sex, and ethnicity (Japanese). Diagnosis was made according to the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, criteria. CSF C5 levels were measured by enzyme-linked immunosorbent assay. CSF C5 levels were significantly increased in the patients with MDD (p < 0.001) and in the patients with schizophrenia (p = 0.001), compared with the healthy controls. The rate of individuals with an "abnormally high C5 level" (i.e., above the 95th percentile value of the control subjects) was significantly increased in all psychiatric groups, relative to the control group (all p < 0.01). Older age, male sex, and greater body mass index tended to associate with higher C5 levels. There was a significantly positive correlation between C5 levels and chlorpromazine equivalent dose in the patients with schizophrenia. Thus, we found, for the first time, elevated C5 levels in the CSF of patients with major psychiatric disorders. Our results suggest that the activated complement system may contribute to neurological pathogenesis in a portion of patients with major psychiatric disorders. PMID- 29454969 TI - JIP3 knockout protects mice against high fat diet-induced liver injury. AB - Multiple pathways contribute to nonalcoholic fatty liver disease (NAFLD) in response to high fat diets (HFD). A homolog of mammalian JNK-interacting protein 3 (JIP3), also known as JSAP-1, activates different components in various signaling pathways to modulate cellular processes. The purpose of this study was to examine the role of JIP3 in obesity-related pathologies pathway. Wild-type (WT) C57BL/6 and JIP3-knockout (JIP3-/-) mice were randomized to chow or HFD. HFD fed WT mice increased hepatic JIP3 expression. Mice lacking JIP3 exhibited reduced weight gain, hepatic steatosis, insulin resistance, lipid accumulation, oxidative stress and inflammatory response in mice fed a HFD, which were, importantly, dependent on various signaling pathways. Lipogenesis-linked pathway was inhibited in JIP3-/- mice after HFD, while PPARalpha/gamma were increased. Additionally, JIP3-/- inhibited hepatic oxidative stress, evidenced by down regulation of total reactive oxygen species (ROS), H2O2, O2.-, malondialdehyde (MDA), xanthine oxidase (XO), inducible nitric oxide synthase (iNOS), and up regulation of superoxide dismutase (SOD) and total antioxidant capacity (TAC) in mice after HFD feeding, which might be related to nuclear respiratory factor 2 (Nrf-2) pathway activation. Further, inflammatory response was blocked in JIP3-/- mice fed with HFD. The process might be attributed to the suppression of toll like receptors (TLRs), p-nuclear factor kappa B (NF-kappaB) and p-c-Jun-N terminal kinase (JNK). Thus, JIP3 absence is associated with decreased lipogenesis, oxidative stress and inflammation, supplying a new target for NAFLD treatment.

AB - Mercury (Hg) is a highly biotoxic heavy metal that contaminates the environment. Phytoremediation is a green technology for environmental remediation and is used to clean up Hg contaminated soil in recent years. In this study, we isolated an ATP-binding cassette (ABC) transporter gene PtABCC1 from Populus trichocarpa and overexpressed it in Arabidopsis and poplar. The transgenic plants conferred higher Hg tolerance than wild type (WT) plants, and overexpression of PtABCC1 could lead to 26-72% or 7-160% increase of Hg accumulation in Arabidopsis or poplar plants, respectively. These results demonstrated that PtABCC1 plays a crucial role in enhancing tolerance and accumulation to Hg in plants, which provides a promising way for phytoremediation of Hg contamination. PMID- 29454972 TI - Enhanced Recovery After Surgery Pathway in Patients Undergoing Open Radical Cystectomy Is Safe and Accelerates Bowel Function Recovery. AB - OBJECTIVE: To assess whether an Enhanced Recovery After Surgery pathway was associated with a faster bowel function recovery and no increase in morbidity compared with standard perioperative care in a contemporary series of patients undergoing radical cystectomy. METHODS: A prospective single-center single surgeon cohort of 114 consecutive patients treated with open radical cystectomy between July 2013 and June 2016 was analyzed. A study group of 74 patients with Enhanced Recovery After Surgery pathway was compared with a control group of 40 patients with standard perioperative care. Primary outcome was recovery of bowel function, measured by resumption of bowel sounds, passage of flatus, and passage of stool. Secondary outcome was rate of overall and major 90-day postoperative complications. RESULTS: Bowel function recovery was significantly faster in the study group. Resumption of bowel sounds on postoperative day 1 was recorded in 43 (58%) vs 4 (10%) patients, passage of flatus within postoperative day 2 in 41 (55%) vs 11 (28%) patients, and passage of stool within postoperative day 3 in 37 (50%) vs no patients in the study vs control group, respectively (P < .01 for all). Overall and major 90-day complications were observed in 35 (47.3%) and 13 (17.6%) patients in the study group, and in 25 (62.5%) and 9 (22.5%) patients in the control group (P = .14 and 0.38, respectively). CONCLUSION: In patients undergoing open radical cystectomy, an Enhanced Recovery After Surgery pathway allowed a significantly faster bowel function recovery with no increase in 90-day postoperative complications compared with standard perioperative care. PMID- 29454973 TI - Comparison of dual mobility total hip arthroplasty and bipolar arthroplasty for femoral neck fractures: A retrospective case-control study of 199 hips. AB - BACKGROUND: The choice between performing total hip arthroplasty (THA) or hemiarthroplasty (HA) is not straightforward in older patients with femoral neck fracture, particularly when co-morbidities are factored in. This led us to carry out a case-control study to determine (1) the rate of mechanical complications for these two types of implants, and (2) the rate of medical complications and mortality. HYPOTHESIS: THA with dual mobility cup (DM) will result in fewer mechanical complications than HA. PATIENTS AND METHODS: This was a single-center, retrospective case-control study. Between 2010 and 2015, all patients with a femoral neck fracture treated by HA or DM THA were included. The primary outcome was the occurrence of any type of surgical complication. The Charlson Co morbidity Index (CCI) and the independence during Activities of Daily Living (ADL) score were calculated for every patient. Two subgroups of patients were made based on whether they met frailty criteria. The effect of covariates on 1 year mortality was controlled using Cox's proportional hazards regression model. RESULTS: The cohort consisted of 101 HA and 98 THA procedures in 193 patients (139 women, 54 men) with a mean age of 80.6years (range, 76-101). The mean follow up was 24.2months (range, 0-83) with a median of 14.5months. Fifteen of the HA hips (15%) had surgical complication, of which 10 were posterior dislocations (10%). Ten patients in the HA cohort had a serious medical complication (10%). Ten of the THA hips (10%) had a mechanical complication, including three posterior dislocations (3%) and four infections (4%). Nine patients in the THA cohort had a medical complication (9%). There were significantly fewer posterior dislocations in the THA hips (p = 0.05). In the subgroup analysis, the 117 patients (58%) who met the frailty criteria had a significantly lower dislocation rate after undergoing THA (p = 0.048). After adjusting on age, ADL and CCI score, the dislocation rate no longer differed significantly between the two groups (p = 0.1). The dislocation rate was lower in the THA hips only in the "frail" patients (Odds ratio = 0.137, 95% CI: [0.003-0.97] (p = 0.04)). There was no difference in the dislocation rate in the "non-frail" patients. The overall 1-year mortality was 85% [95% CI: 78-94%]. It was 78% [95% CI: 69-86%] for the HA hips and 88% [95% CI: 82-95%] for the THA hips (p = 0.01). After factoring in the impact of age, CCI and ADL, the differences in the 1-year mortality between HA and THA were no longer present (p = 0.42). Thus, there is no increased risk of mortality in THA patients. DISCUSSION: When the CCI and independence level are taken into consideration, the frailest patients can undergo DM THA to reduce the dislocation risk, without increasing the mortality rate at 1year. Patients who are not frail will benefit equally from undergoing HA or THA. LEVEL OF EVIDENCE: III, case control study. PMID- 29454974 TI - Proof of patient information: Analysis of 201 judicial decisions. AB - INTRODUCTION: The ruling by the French Court of Cassation dated February 25, 1997 obliged doctors to provide proof of the information given to patients, reversing more than half a century of case law. In October 1997, it was specified that such evidence could be provided by "all means", including presumption. No hierarchy in respect of means of proof has been defined by case law or legislation. The present study analyzed judicial decisions with a view to determining the means of proof liable to carry the most weight in a suit for failure to provide due patient information. MATERIAL AND METHOD: A retrospective qualitative study was conducted for the period from January 2010 to December 2015, by a search on the LexisNexis(r) JurisClasseur website. Two hundred and one judicial decisions relating to failure to provide due patient information were selected and analyzed to study the characteristics of the practitioners involved, the content of the information at issue and the means of proof provided. The resulting cohort of practitioners was compared with the medical demographic atlas of the French Order of Medicine, considered as exhaustive. RESULTS: Two hundred and one practitioners were investigated for failure to provide information: 45 medical practitioners (22+/-3%), and 156 surgeons (78+/-3%) including 45 orthopedic surgeons (29+/-3.6% of surgeons). Hundred and ninety-three were private sector (96+/-1.3%) and 8 public sector (4+/-1.3%). Hundred and one surgeons (65+/-3.8% of surgeons), and 26 medical practitioners (58+/-7.4%) were convicted. Twenty-five of the 45 orthopedic surgeons were convicted (55+/-7.5%). There was no significant difference in conviction rates between surgeons and medical practitioners: odds ratio, 1.339916; 95% CI [0.6393982; 2.7753764] (Chi2 test: p=0.49). Ninety-two practitioners based their defense on a single means of proof, and 74 of these were convicted (80+/-4.2%). Forty practitioners based their defense on several means of proof, and 16 of these were convicted (40+/-7.8%). There was a significant difference in conviction rate according to reliance on single or multiple evidence of delivery of information: odds ratio, 0.165; 95% CI [0.07; 0.4] (Chi2 test: p=1.1*10-5). DISCUSSION: This study shows that surgeons, and orthopedic surgeons in particular, are more at risk of being investigated for failure to provide due patient information (D=-0.65 [-0.7; -0.6]). They are not, however, more at risk of conviction (p=0.49). Being in private practice also appeared to be a risk factor for conviction of failure to provide due information. Offering several rather than a single means of proof of delivery of information significantly reduces the risk of conviction (p=1.1*10-5). LEVEL OF EVIDENCE: Level IV: Retrospective study. PMID- 29454975 TI - Prefrontal cortex activation during obstacle negotiation: What's the effect size and timing? AB - BACKGROUND: Obstacle negotiation is a daily activity that requires the integration of sensorimotor and cognitive information. Recent studies provide evidence for the important role of prefrontal cortex during obstacle negotiation. We aimed to explore the effects of obstacle height and available response time on prefrontal activation. METHODS: Twenty healthy young adults (age: 30.1 +/- 1.0 years; 50% women) walked in an obstacle course while negotiating anticipated and unanticipated obstacles at heights of 50 mm and 100 mm. Prefrontal activation was measured using a functional near-infrared spectroscopy system. Kinect cameras measured the obstacle negotiation strategy. Prefrontal activation was defined based on mean level of HbO2 before, during and after obstacle negotiation and the HbO2 slope from gait initiation and throughout the task. Changes between types of obstacles were assessed using linear-mix models and partial correlation analyses evaluated the relationship between prefrontal activation and the distance between the feet as the subjects traversed the obstacles. RESULTS: Different obstacle heights showed similar changes in prefrontal activation measures (p > 0.210). However, during unanticipated obstacles, the slope of the HbO2 response was steeper (p = 0.048), as compared to anticipated obstacles. These changes in prefrontal activation during negotiation of unanticipated obstacles were correlated with greater distance of the leading foot after the obstacles (r = 0.831, p = 0.041). CONCLUSIONS: These findings are the first to show that the pattern of prefrontal activation depends on the nature of the obstacle. More specifically, during unanticipated obstacles the recruitment of the prefrontal cortex is faster and greater than during negotiating anticipated obstacles. These results provide evidence of the important role of the prefrontal cortex and the ability of healthy young adults to tailor the activation pattern to different types of obstacles. PMID- 29454976 TI - Defective Endogenous Pain Modulation in Fibromyalgia: A Meta-Analysis of Temporal Summation and Conditioned Pain Modulation Paradigms. AB - : To study the characteristics of temporal summation (TS) and conditioned pain modulation (CPM) in fibromyalgia (FM) patients, we systematically searched Pubmed and EMBASE for studies using TS or CPM comparing FM patients with healthy controls. We computed Hedges' g, risk of bias, sensitivity analysis, and meta regression tests with 10,000 Monte-Carlo permutations. Twenty-three studies (625 female and 23 male FM patients and 591 female and 81 male healthy controls) were included. The meta-analyses showed an effect size of .53 for TS (P < .001; 95% confidence interval = .23-.83), which is a 68% relative difference between patients and controls, and of .57 for CPM (P < .001; 95% confidence interval = .88 to -.26), representing a 65% relative difference between the groups. The qualitative analyses revealed large heterogeneity between study protocols. Although studies were of low risk of bias, lack of blinding was substantial. Sensitivity analysis and meta-regression identified type and site of stimulation, age, lab, sample size, and medication control as important sources of between study variability. We showed a significant alteration of pain modulation mechanisms in FM patients. PERSPECTIVE: This novel meta-analysis provides evidence for defective endogenous pain modulation in FM patients. We explored the effect of covariates on between-study variability in these paradigms. These biomarkers may aid in diagnosis, and treatment of patients. However, validation requires further investigation under strict methodological settings, and into individual patient covariates. PMID- 29454977 TI - Neural networks in bottom up 'experiential emotion regulation'. AB - Emotion regulation is thought to differ in when and how it influence emotion, well being and representation in the brain. While previous research on ER has focused on gray matter correlates, this study represents the first exploratory study on white matter integrity of brain networks of ER. Responding to the gap between cognitive and affective approaches of ER, pertaining to some of the daily emotional stressors, the present study investigates a complementary experiential approach such as 'Emotional approach' or the tendency to affectively acknowledge, understand and express emotional experience (cf. Stanton et al., 2000). Diffusion tensor magnetic resonance imaging (DTI-MRI) measures of fractional anisotropy (FA) and mean diffusivity (MD) evaluated dispositional ER in a group of 21 women with (1) a 'high emotional approach' (HEA) (N = 11) and (2) a 'low emotional approach' (LEA) (N = 10). HEA exhibited more FA of the cingulum supporting emotion processing and emotion regulation, whereas LEA showed a higher FA in the right corticospinal tracts supporting automatic action tendencies and together with a higher FA in the superior longitudinal fasciculus (SLF), cognitive control tasks and monitoring of emotion. LEA also correlated with a significant increase in MD in the body (p. = 0.05) and in the splenium of the corpus callosum (CC). A higher FA in the inferior longitudinal fasciculus (IFL) may indicate higher visual- affective integration within emotion processing, whereas more MD in the body and splenium of the CC decreases the interhemispheric integration of emotional information within emotion processing and emotion regulation. PMID- 29454978 TI - Ribonucleotide reductase as a drug target against drug resistance Mycobacterium leprae: A molecular docking study. AB - Leprosy is a chronic infection of skin and nerve caused by Mycobacterium leprae. The treatment is based on standard multi drug therapy consisting of dapsone, rifampicin and clofazamine. The use of rifampicin alone or with dapsone led to the emergence of rifampicin-resistant Mycobacterium leprae strains. The emergence of drug-resistant leprosy put a hurdle in the leprosy eradication programme. The present study aimed to predict the molecular model of ribonucleotide reductase (RNR), the enzyme responsible for biosynthesis of nucleotides, to screen new drugs for treatment of drug-resistant leprosy. The study was conducted by retrieving RNR of M. leprae from GenBank. A molecular 3D model of M. leprae was predicted using homology modelling and validated. A total of 325 characters were included in the analysis. The predicted 3D model of RNR showed that the phi and phi angles of 251 (96.9%) residues were positioned in the most favoured regions. It was also conferred that 18 alpha-helices, 6 beta turns, 2 gamma turns and 48 helix-helix interactions contributed to the predicted 3D structure. Virtual screening of Food and Drug Administration approved drug molecules recovered 1829 drugs of which three molecules, viz., lincomycin, novobiocin and telithromycin, were taken for the docking study. It was observed that the selected drug molecules had a strong affinity towards the modelled protein RNR. This was evident from the binding energy of the drug molecules towards the modelled protein RNR (-6.10, -6.25 and -7.10). Three FDA-approved drugs, viz., lincomycin, novobiocin and telithromycin, could be taken for further clinical studies to find their efficacy against drug resistant leprosy. PMID- 29454979 TI - Variants of TLR1 associated with tuberculosis susceptibility in the Chinese Tibetan population but not in Han Chinese. AB - Toll-like receptor 1 (TLR1) participates in the innate immune response to Mycobacterium tuberculosis. This study mainly investigated the relationship between polymorphisms of TLR1 and tuberculosis (TB) susceptibility in the two Chinese populations. Totally, 1185 Han and 1216 Tibetan participants were enrolled. TagSNPs of TLR1 were selected and genotyped. Analyses of linkage disequilibrium and haplotypes were performed by software Haploview and SHEsis. Gene-gene interactions were evaluated using the nonparametric multifactor dimensionality reduction (MDR) method. Gene-by-sex interaction in the Tibetan population and gene-by-smoking interaction in the Han population were also calculated. Association between rs4833095 and TB susceptibility was evaluated by meta-analysis. In the Tibetan population, the A alleles of rs5743557 and rs5743596 were related with reduced tuberculosis risk (p < 0.001 and p = 0.001) after adjusting for confounding factors. Additionally, rs5743604_A was associated with increased TB susceptibility (p = 0.004). The frequency of haplotype rs4833095-rs5743557-rs5743596-rs5743604 CAAG was significantly higher in the healthy controls (HC) group (p = 0.0009), while frequency of haplotype CGGA was higher in the TB group (p = 0.001). Significant associations were detected between rs4833095-rs5743557-rs5743604 interactions and TB susceptibility. Interactions between rs5743596 and sex in the Tibetan population, between rs5743604 and smoking in the Han population were revealed as well. However, no significant main effects were observed in the Han population. The rs4833095 was not associated with TB susceptibility after meta-analysis either. Our study suggested that SNPs of the TLR1 gene were associated with TB susceptibility in the Chinese Tibetan population, but not in the Han population. PMID- 29454981 TI - Natural products as inhibitors of prostaglandin E2 and pro-inflammatory 5 lipoxygenase-derived lipid mediator biosynthesis. AB - Non-steroidal anti-inflammatory drugs (NSAIDs) inhibit prostanoid formation and represent prevalent therapeutics for treatment of inflammatory disorders. However, NSAIDs are afflicted with severe side effects, which might be circumvented by more selective suppression of pro-inflammatory eicosanoid biosynthesis. This concept led to dual inhibitors of microsomal prostaglandin E2 synthase (mPGES)-1 and 5-lipoxygenase that are crucial enzymes in the biosynthesis of pro-inflammatory prostaglandin E2 and leukotrienes. The potential of their dual inhibition in light of superior efficacy and safety is discussed. Focus is placed on natural products, for which direct inhibition of mPGES-1 and leukotriene biosynthesis has been confirmed. PMID- 29454980 TI - Cumulative incidence of suicidal ideation and associated factors among adults living in temporary housing during the three years after the Great East Japan Earthquake. AB - BACKGROUND: The effect of disasters on suicidality is not known. We aimed to retrospectively determine the cumulative incidence of suicidal ideation during the 3 years after the Great East Japan Earthquake among residents in temporary housing without prior suicidal ideation, as compared to the general population. Moreover, we aimed to identify the risk factors for the onset of suicidal ideation. METHODS: A cross-sectional survey involving face-to-face interviews was conducted 3 years after the earthquake with adult community residents in disaster affected areas and a control area using the World Health Organization Composite International Diagnostic Interview version 3.0. We compared the cumulative incidence of suicidal ideation between the two areas using the Cox proportional hazard model and examined risk factors for the onset of suicidal ideation using a multiple logistic regression analysis. RESULTS: Among 1019 respondents in the disaster-affected areas, the cumulative incidence of suicidal ideation over 1, 2, and 3 years after the earthquake was 1.4%, 2.4%, and 2.8%, respectively, which was significantly higher than that in the control area. Not being married, being injured in the disaster, and poor subjective physical health were associated with the onset of suicidal ideation. LIMITATIONS: We estimated the time of onset of suicidal ideation based on the respondents' current age and self-reported onset age, which limits the accuracy of the onset timing. CONCLUSIONS: We revealed a higher incidence of suicidal ideation in temporary housing residents and identified several risk factors, which suggests the importance of developing countermeasures to prevent suicide after a disaster. PMID- 29454982 TI - Improved genomic resources and new bioinformatic workflow for the carcinogenic parasite Clonorchis sinensis: Biotechnological implications. AB - Clonorchis sinensis (family Opisthorchiidae) is an important foodborne parasite that has a major socioeconomic impact on ~35 million people predominantly in China, Vietnam, Korea and the Russian Far East. In humans, infection with C. sinensis causes clonorchiasis, a complex hepatobiliary disease that can induce cholangiocarcinoma (CCA), a malignant cancer of the bile ducts. Central to understanding the epidemiology of this disease is knowledge of genetic variation within and among populations of this parasite. Although most published molecular studies seem to suggest that C. sinensis represents a single species, evidence of karyotypic variation within C. sinensis and cryptic species within a related opisthorchiid fluke (Opisthorchis viverrini) emphasise the importance of studying and comparing the genes and genomes of geographically distinct isolates of C. sinensis. Recently, we sequenced, assembled and characterised a draft nuclear genome of a C. sinensis isolate from Korea and compared it with a published draft genome of a Chinese isolate of this species using a bioinformatic workflow established for comparing draft genome assemblies and their gene annotations. We identified that 50.6% and 51.3% of the Korean and Chinese C. sinensis genomic scaffolds were syntenic, respectively. Within aligned syntenic blocks, the genomes had a high level of nucleotide identity (99.1%) and encoded 15 variable proteins likely to be involved in diverse biological processes. Here, we review current technical challenges of using draft genome assemblies to undertake comparative genomic analyses to quantify genetic variation between isolates of the same species. Using a workflow that overcomes these challenges, we report on a high-quality draft genome for C. sinensis from Korea and comparative genomic analyses, as a basis for future investigations of the genetic structures of C. sinensis populations, and discuss the biotechnological implications of these explorations. PMID- 29454983 TI - Old and new glycopeptide antibiotics: From product to gene and back in the post genomic era. AB - Glycopeptide antibiotics are drugs of last resort for treating severe infections caused by multi-drug resistant Gram-positive pathogens. First-generation glycopeptides (vancomycin and teicoplanin) are produced by soil-dwelling actinomycetes. Second-generation glycopeptides (dalbavancin, oritavancin, and telavancin) are semi-synthetic derivatives of the progenitor natural products. Herein, we cover past and present biotechnological approaches for searching for and producing old and new glycopeptide antibiotics. We review the strategies adopted to increase microbial production (from classical strain improvement to rational genetic engineering), and the recent progress in genome mining, chemoenzymatic derivatization, and combinatorial biosynthesis for expanding glycopeptide chemical diversity and tackling the never-ceasing evolution of antibiotic resistance. PMID- 29454984 TI - Adenovirus-mediated OX40Ig gene transfer induces long-term survival of orthotopic liver allograft in rats. AB - BACKGROUND: To discuss the effect and mechanism of adenovirus-mediated OX40Ig gene transfer in inducing long-term survival of liver allografts in rats. METHODS: Orthotopic liver transplantation was performed from Lewis to Brown Norway (BN) rats through the modified two-cuffed technique, and all rats were randomly divided equally into four groups: control, AdEGFP, AdOX40Ig, and FK506. The survival times of the rats were recorded. The rats' liver function, serum cytokines, hepatocyte pathology, OX40Ig protein level, and mixed lymphocyte reaction (MLR) with or without recombinant interleukin-2 (rIL-2) were evaluated. RESULTS: Compared with the control and AdEGFP groups, the rats in the AdOX40Ig and FK506 groups survived longer (P < 0.05), experienced less damage to hepatic function (P < 0.05), and showed milder hepatic cellular rejection and less hepatic cellular apoptosis. Interferon (IFN)-gamma and IL-2 content in the serum were lower after operation (P < .05) in the AdOX40Ig and FK506 groups. On the contrary, IL-4 and IL-10 content in the serum was higher after operation (P < 0.05) in the AdOX40Ig and FK506 groups. OX40Ig protein was significantly expressed in the AdOX40Ig group and reached the highest level on the 7th day after operation. With respect to the MLR between BN and Lewis rats, the AdOX40Ig group showed a lighter reaction for the same strain than the control and AdEGFP groups (P < 0.05), which is different from the MLR between BN and F344 rats. After adding rIL-2 to the MLR system between BN rats in the AdOX40Ig group and Lewis rats, MLR was aggravated. CONCLUSION: Through OX40/OX4OL pathways, OX40Ig created an immunosuppressive effect after liver transplantation in rats. This immunosuppressive effect is associated with reduced IL-2 and can be reversed by adding IL-2 with antigen specificity. PMID- 29454985 TI - A non-toxic microbial surfactant from Marinobacter hydrocarbonoclasticus SdK644 for crude oil solubilization enhancement. AB - This study aims to investigate the ability of a biosurfactant produced by Marinobacter hydrocarbonoclasticus strain SdK644 isolated from hydrocarbon contaminated sediment to enhance the solubilization rate of crude oil contaminated seawater. Phylogenetic analysis shows that strain SdK644 was very closely related to M. hydrocarbonoclasticus with 16S rRNA gene sequence similarity of 97.44%. Using waste frying oil as inducer carbon source, the producing biosurfactant by strain SdK644 was applied to improve crude oil solubilization in seawater. The preliminary characterization of the produced biosurfactant by FT-IR analysis indicates its possible classification in a glycolipids group. Results from crude oil solubilization assay showed that SdK644 strain biosurfactant was 2-fold greater than Tween 80 surfactant in crude oil solubilization and 12-fold higher than seawater control, as shown by GC-MS analysis of aliphatic compounds. Furthermore, this bioactive compound was shown to be nontoxic against Artemia larvae in short-term acute toxicity bioassay. Generally, the results showed the possible use of M. hydrocarbonoclasticus strain SdK644 biosurfactant in bioremediation processes of the marine environments. PMID- 29454986 TI - Nano-sized TiO2 (nTiO2) induces metabolic perturbations in Physarum polycephalum macroplasmodium to counter oxidative stress under dark conditions. AB - Nano-sized TiO2 (nTiO2) exerts an oxidative effect on cells upon exposure to solar or UV irradiation and ecotoxicity of the nTiO2 is an urgent concern. Little information is available regarding the effect of TiO2 on cells under dark conditions. Metabolomics is a unique approach to the discovery of biomarkers of nTiO2 cytotoxicity, and leads to the identification of perturbed metabolic pathways and the mechanism underlying nTiO2 toxicity. In the present study, gas chromatography mass spectrometry (GC/MS)-based metabolomics was performed to investigate the effect of nTiO2 on sensitive cells (P. polycephalum macroplasmodium) under dark conditions. According to the multivariate pattern recognition analysis, at least 60 potential metabolic biomarkers related to sugar metabolism, amino acid metabolism, nucleotide metabolism, polyamine biosynthesis, and secondary metabolites pathways were significantly perturbed by nTiO2. Notably, many metabolic biomarkers and pathways were related to anti-oxidant mechanisms in the living organism, suggesting that nTiO2 may induce oxidative stress, even under dark conditions. This speculation was further validated by the biochemical levels of reactive oxygen species (ROS), 8-hydroxy-2-deoxyguanosine (8-OHdG), and total soluble phenols (TSP). We inferred that the oxidative stress might be related to nTiO2-induced imbalance of cellular ROS. To the best of our knowledge, the present study is the first to investigate the nTiO2-induced metabolic perturbations in slime mold, provide a new perspective of the mechanism underlying nTiO2 toxicity under dark conditions, and show that metabolomics can be employed as a rapid, reliable and powerful tool to investigate the interaction among organisms, the environment, and nanomaterials. PMID- 29454987 TI - Nature differences of humic acids fractions induced by extracted sequence as explanatory factors for binding characteristics of heavy metals. AB - The composition and structure of Humic acid (HA) is so heterogeneous that it brings significant barriers to investigate the interaction between HA and heavy metal ions. The isolation of HA with relatively homogeneity is a key to reveal the binding mechanisms between HA and heavy metals. In this work, ten HA fractions (HAs) were obtained by sequential alkali extraction procedure and nature differences of the extracted HAs were considered as explanatory factors for binding characteristics of Cu2+, Pb2+ and Cd2+. The results indicate that more large molecular weight (MW) HA subunits, less carboxyl and phenolic group contents, weaker aromaticity and polarity were measured with increasing extractions, inducing weaker binding capacity of HAs. Ligand binding and bi Langmuir models indicated that the sorption capacity and binding affinity of earlier extracted HAs were higher than the latter ones. The peak area changes at 3427, 1599, and 619 cm-1 pre- and post-adsorption in FTIR spectra suggested carboxyl, phenolic and nitrogen-containing groups were involved in the adsorption process. At the same time, the peak area difference between HAs and HAs-metal (DeltaS) of phenolic groups were 8.22-20.50, 6.81-21.11 and 10.66-19.80% for Cu2+, Pb2+ and Cd2+, respectively, DeltaS of carboxyl groups 6.64-17.03, 8.96 16.82 and 9.45-17.85% for Cu2+, Pb2+ and Cd2+, respectively, DeltaS of nitrogen containing groups 0.33-0.48, 0.20-1.38 and 0.31-0.59% for Cu2+, Pb2+ and Cd2+, respectively. DeltaS of phenolic and carboxyl groups were larger than those of nitrogen-containing groups, implying that these two groups were the predominant binding sites suppliers for metal ions, which were also supported by the results of correlation analysis. This work is helpful to insight the environmental impacts of natural organic matter and the fate of heavy metals in natural environment. PMID- 29454988 TI - Effect of Bacillus subtilis and NTA-APG on pyrene dissipation in phytoremediation of nickel co-contaminated wetlands by Scirpus triqueter. AB - A complex mix of organic pollutants and heavy metal made the remediation of contaminated wetlands more difficult. Few research focus on the remediation for pyrene enhanced by chemical reagents and pyrene degrading bacteria in the nickel co-contaminated soil. In this paper, the effect of chemical reagents (nitrilotriacetic acid and alkyl polyglucoside) and Bacillus subtilis on pyrene dissipation in phytoremediation of nickel co-contaminated soil by Scirpus triqueter was investigated. Similar seedlings of Scirpus triqueter were moved to uncontaminated soil and pyrene-nickel co-contaminated soil. The pots (14.8 cm diameter and 8.8 cm height) were set up in greenhouse and treated in different ways. After 60 days, plant biomass, radial oxygen loss (ROL), soil dehydrogenase activity (DHA) and pyrene concentration in soil were determined. Results showed that ROL rate and DHA in different groups was positively correlated with pyrene dissipation from soil. In the process of remediation, chemical reagents might have an indirect slight effect on pyrene dissipation (pyrene dissipation increased 21%) by affecting DHA firstly and redistributing pyrene fractions in the presence of pyrene degrading bacteria. Pyrene degrading bacteria were likely to affect pyrene dissipation by impacting ROL rate and DHA and played a more vital role in contributing to pyrene dissipation (pyrene dissipation increased 45%) from wetland. This study demonstrated that phytoremediation for pyrene in nickel co-contaminated soil by Scirpus triqueter can be enhanced by the application of NTA-APG and pyrene degrading bacteria and they could be reasonably restore the ecological environment of PAH-contaminated wetlands. PMID- 29454989 TI - One year study of PM2.5 in Xinxiang city, North China: Seasonal characteristics, climate impact and source. AB - This study was conducted in order to explore the seasonal characteristics, climate impact and source of PM2.5 in Xinxiang, China. Daily PM2.5 samples were collected at urban site from January to December in 2015. Average PM2.5 concentration was 100.6 +/- 65.8 MUg m-3 in Xinxiang, which was several times higher than China Ambient Air Quality Standards (GB3095-2012). Secondary inorganic aerosols (SIA) constituted 70% of the total ionic concentrations. The average concentration of SO42- was 6.4 +/- 12.0 MUg m-3, which ranked the highest among the water-soluble ions analyzed. Seasonal variations of PM2.5 and its major chemical components were significant, most of them with high values in winter and the lowest values in summer, especially with heavier PM2.5 events (more than 200 MUg/m3) in December. SIA and OC on polluted days were 2.1-2.3 times higher than those of on clean days. It was estimated that Fe, Li, Na, Mg, Al, K, Ca and Sr were emitted from crustal sources and Pb, Cr, Ni, Cu, Zn, As, Cd and V were emitted from anthropogenic emissions using the EF values. Analysis using the tracer and PCA/MLR revealed that vehicle exhausts were the most important source of PM2.5, which contributed 26.9% of PM2.5 over the whole study period. This study provides detailed composition data and first comprehensive analysis of PM2.5 in Xinxiang during a whole year.

AB - Aniline aerofloat (AAF), a high-toxic organic flotation reagent, is widely used in mineral processing industry. However, little information on its environmental fate is available. AAF sorption to four types of agricultural soils at low concentrations (1-10 mg/L) was investigated using batch experiments. AAF sorption kinetics involved both boundary layer diffusion and intraparticle diffusion, following pseudo-second-order kinetics with equilibrium time within 120 min. Both Langmuir and Freundlich models fitted well the AAF sorption with the former better. Sorption of AAF to soils was a spontaneous and favorable physical sorption that was controlled by ion bridge effect and hydrophobic interaction that was related to van der Waals force and pi-pi coordination based on FTIR analyses. AAF sorption was remarkably affected by soil constituents, positively correlating with the contents of organic matter and clay. The relatively higher logKoc values (3.53-4.66) of AAF at environmental concentrations (1-5 mg/L) imply that soils are serving as a sink of AAF from beneficiation wastewater, posing great potential risks to environment and human health. PMID- 29454991 TI - Toxicological effect of underutilized plant, Cleistanthus collinus leaf extracts against two major stored grain pests, the rice weevil, Sitophilus oryzae and red flour beetle, Tribolium castaneum. AB - Toxicity and repellency activity of Cleistanthus collinus (Roxb.) (CC) leaf extracts were evaluated against rice weevil, Sitophilus oryzae (L.) and red flour beetle, Tribolium castaneum (Herbst) under laboratory condition. Five concentration(s) (1%, 1.5%, 2%, 2.5% and 4%) with two controls (acetone and water) treatments along with deltamethrin were used for direct and contact residual toxicity. The insect that survived after CC exposure were transferred to an untreated feeding substrate and the population buildup of subsequent two generation were recorded after 30 (F1) and 60 days (F2). In the contact residual toxicity, highest CC concentration (4%) produced 75% mortality in S. oryzae and 62.5% mortality in T. castaneum during 7 days of exposure, whereas in direct toxicity the mortality were 81% and 58% respectively, for S. oryzae and T. castaneum. The long term effect of CC was apparent in both the insect species, where F2 populations were significantly decreased in the CC treatments. CC treatment at 4% produced similar adult mortality in comparison to deltamethrin at 1%. In addition, repellent activity of CC extracts was observed against both S. oryzae and T. castaneum. This is the first step towards assessing the scientific basis for the understanding the effectiveness of CC extracts against stored grain pests and it could be a viable eco-friendly option for stored grain insect pest management. PMID- 29454992 TI - A novel beta-glucosidase isolated from the microbial metagenome of Lake Poraque (Amazon, Brazil). AB - The Amazon region holds most of the biological richness of Brazil. Despite their ecological and biotechnological importance, studies related to microorganisms from this region are limited. Metagenomics leads to exciting discoveries, mainly regarding non-cultivable microorganisms. Herein, we report the discovery of a novel beta-glucosidase (glycoside hydrolase family 1) gene from a metagenome from Lake Poraque in the Amazon region. The gene encodes a protein of 52.9 kDa, named AmBgl-LP, which was recombinantly expressed in Escherichia coli and biochemically and structurally characterized. Although AmBgl-LP hydrolyzed the synthetic substrate p-nitrophenyl-beta-d-glucopyranoside (pNPbetaG) and the natural substrate cellobiose, it showed higher specificity for pNPbetaG (kcat/Km = 6 s 1.mM-1) than cellobiose (kcat/Km = 0.6 s-1.mM-1). AmBgl-LP showed maximum activity at 40 degrees C and pH 6.0 when pNPbetaG was used as the substrate. Glucose is a competitive inhibitor of AmBgl-LP, presenting a Ki of 14 mM. X-ray crystallography and Small Angle X-ray Scattering were used to determine the AmBgl LP three-dimensional structure and its oligomeric state. Interestingly, despite sharing similar active site architecture with other structurally characterized GH1 family members which are monomeric, AmBgl-LP forms stable dimers in solution. The identification of new GH1 members by metagenomics might extend our understanding of the molecular mechanisms and diversity of these enzymes, besides enabling us to survey their industrial applications. PMID- 29454993 TI - In vitro studies of disease-linked variants of human tRNA nucleotidyltransferase reveal decreased thermal stability and altered catalytic activity. AB - Mutations in the human TRNT1 gene encoding tRNA nucleotidyltransferase (tRNA-NT), an essential enzyme responsible for addition of the CCA (cytidine-cytidine adenosine) sequence to the 3'-termini of tRNAs, have been linked to disease phenotypes including congenital sideroblastic anemia with B-cell immunodeficiency, periodic fevers and developmental delay (SIFD) or retinitis pigmentosa with erythrocyte microcytosis. The effects of these disease-linked mutations on the structure and function of tRNA-NT have not been explored. Here we use biochemical and biophysical approaches to study how five SIFD-linked amino acid substitutions (T154I, M158V, L166S, R190I and I223T), residing in the N terminal head and neck domains of the enzyme, affect the structure and activity of human tRNA-NT in vitro. Our data suggest that the SIFD phenotype is linked to poor stability of the T154I and L166S variant proteins, and to a combination of reduced stability and altered catalytic efficiency in the M158 V, R190I and I223T variants. PMID- 29454994 TI - Epigallocatechin-3-gallate loaded PEGylated-PLGA nanoparticles: A new anti seizure strategy for temporal lobe epilepsy. AB - Temporal lobe epilepsy is the most common type of pharmacoresistant epilepsy in adults. Epigallocatechin-3-gallate has aroused much interest because of its multiple therapeutic effects, but its instability compromises the potential effectiveness. PEGylated-PLGA nanoparticles of Epigallocatechin-3-gallate were designed to protect the drug and to increase the brain delivery. Nanoparticles were prepared by the double emulsion method and cytotoxicity, behavioral, Fluoro Jade C, Iba1 and GFAP immunohistochemistry studies were carried out to determine their effectiveness. Nanoparticles showed an average size of 169 nm, monodisperse population, negative surface charge, encapsulation efficiency of 95% and sustained release profile. Cytotoxicity assays exhibited that these nanocarriers were non-toxic. Behavioral test showed that nanoparticles reduced most than free drug the number of epileptic episodes and their intensity. Neurotoxicity and immunohistochemistry studies confirmed a decrease in neuronal death and neuroinflammation. In conclusion, Epigallocatechin-3-gallate PEGylated-PLGA nanoparticles could be a suitable strategy for the treatment of temporal lobe epilepsy. PMID- 29454996 TI - Apo-10'-lycopenoic acid inhibits cancer cell migration and angiogenesis and induces peroxisome proliferator-activated receptor gamma. AB - SCOPE: We have previously shown that apo-10'-lycopenoic acid (ALA), a derivative of lycopene through cleavage by carotene-9',10'-oxygenase, inhibits tumor progression and metastasis in both liver and lung cancer animal models. The underlying mechanism remains unknown. We hypothesized that ALA inhibits cancer cell motility and angiogenesis by up-regulating peroxisome proliferator-activated receptor gamma (PPARgamma) which is involved in controlling angiogenesis, tumor progression and metastasis. METHODS AND RESULTS: ALA treatment, in dose-dependent manner, was effective at inhibiting migration and invasion of liver and lung cancer cells (HuH7 and A549) in both Transwell and wound-healing models, as well as suppressing actin remodeling and ruffling/lamellipodia formation in HuH7 and immortalized lung BEAS-2B cells. ALA treatment resulted in suppression of angiogenesis in both tube formation and aortic ring assays and inhibition of matrix metalloproteinase-2 expression and activation in both HuH7 and A549 cells. Additionally, ALA dose-dependently increased the mRNA expression and protein levels of PPARgamma in human THLE-2 liver cells. CONCLUSION: ALA inhibits cancer cell motility and angiogenesis and induces PPARgamma expression, which could be one of the potential mechanisms for ALA protecting against tumor progression. PMID- 29454995 TI - Role of HBx in hepatitis B virus persistence and its therapeutic implications. AB - Chronic hepatitis B virus infection is a significant risk factor for cirrhosis and hepatocellular carcinoma. The HBx protein is required for virus replication, but the lack of robust infection models has hindered our understanding of HBx functions that could be targeted for antiviral purposes. We briefly review three properties of HBx: its binding to DDB1 and its regulation of cell survival and metabolism, to illustrate how a single viral protein can have multiple effects in a cell. We propose that different functions of HBx are needed, depending on the changing hepatocyte environment encountered during a chronic virus infection, and that these functions might serve as novel therapeutic targets for inhibiting hepatitis B virus replication and the development of associated diseases. PMID- 29454997 TI - Regulatory responses of hepatocytes, macrophages and vascular endothelial cells to magnesium deficiency. AB - The liver is the organ that responds to nutritional disturbances including magnesium deficiency. The present study evaluated cellular responses to magnesium deficiency using model cells of the liver, namely, HepG2 cells as hepatocytes, RAW264.7 cells as Kupffer cells and human umbilical vein endothelial cells (HUVECs) as vascular endothelial cells; we examined effects of culture with magnesium deficient medium on cell responses in individual types of cells as well as interactive responses among cells. Metabolomic analyses indicated that magnesium deficiency differentially affected the cellular content of metabolites among HepG2 cells, RAW264.7 cells and HUVECs. The cellular content of the metabolites in HepG2 cells and HUVECs was also affected by the conditioned medium from RAW264.7 cells cultured with the magnesium-deficient media. The changes in HUVECs partly resembled those of the livers of magnesium-deficient rats previously described. RNA-seq analyses indicated that magnesium deficiency modulated the expression levels of molecules related to the ubiquitin-proteasome pathway and oxidative stress/antioxidant response in HepG2 cells and RAW264.7 cells, respectively. Furthermore, when HUVECs were co-cultured with RAW264.7 cells, lipopolysaccharide-induced expression of interleukin (IL)-1beta and IL-6 was enhanced by magnesium deficiency, depending on the presence of RAW264.7 cells. The present study reveals that magnesium deficiency affects cellular metabolism in HepG2 liver cells, RAW264.7 macrophages and HUVECs, and that the modulation of cellular responses to extracellular magnesium deficiency in HUVECs depends on the presence of RAW264.7 cells. The complex responses in individual cells and through cell interactions partly explain the regulatory reaction to magnesium deficiency in the liver. PMID- 29454998 TI - A cell death assay for assessing the mitochondrial targeting of proteins. AB - The mitochondrial proteome comprises 1000 to 1500 proteins, in addition to proteins for which the mitochondrial localization is uncertain. About 800 diseases have been linked with mutations in mitochondrial proteins. We devised a cell survival assay for assessing the mitochondrial localization in a high throughput format. This protocol allows us to assess the mitochondrial localization of proteins and their mutants, and to identify drugs and nutrients that modulate the mitochondrial targeting of proteins. The assay works equally well for proteins directed to the outer mitochondrial membrane, inner mitochondrial membrane mitochondrial and mitochondrial matrix, as demonstrated by assessing the mitochondrial targeting of the following proteins: carnitine palmitoyl transferase 1 (consensus sequence and R123C mutant), acetyl-CoA carboxylase 2, uncoupling protein 1 and holocarboxylase synthetase. Our screen may be useful for linking the mitochondrial proteome with rare diseases and for devising drug- and nutrition-based strategies for altering the mitochondrial targeting of proteins. PMID- 29455000 TI - The impact of increased number of low-risk deliveries on maternal and neonatal outcomes: A retrospective cohort study in Finland in 2011-2015. AB - OBJECTIVES: Our aim was to demonstrate the influence of increased number of low risk deliveries on obstetric and neonatal outcome. STUDY DESIGN: The study hospital was Katiloopisto Maternity Hospital in Helsinki. Simultaneously, we studied all three delivery units in the Helsinki region in the population-based analysis. The study population was singleton hospital deliveries occurring between 2011 and 2012, and 2014-2015. The study hospital included 11 237 and 15 637 births and the population-based group included 28 950 and 27 979 births. We compared outcome measures in different periods by calculating adjusted odds ratios (AOR). Main outcome measures were induced delivery, mode of delivery, third or fourth degree perineal tear, Apgar score at five minutes <7, umbilical artery pH <7.00, transfer to higher level of neonatal care, neonatal antibiotic treatment, respiratory support of the neonate, hospitalization of the neonate >7 days, and perinatal death. RESULTS: In the study hospital, induction rate increased from 22.4% to 24.8% (AOR 1.06, 95% CI; 1.00-1.12) while in the population-based analysis the rate decreased from 22.2% to 21.5% (AOR 0.96, 95% CI; 0.92-1.00). Percentage of neonatal transfers, low Apgar scores, and severe perineal tears increased both in study hospital and in population-based group. Changes in operative delivery rate and other adverse perinatal outcomes were statistically insignificant. CONCLUSIONS: Increasing the volume of a delivery unit does not compromise maternal or neonatal outcome. Specific characteristics of a delivery unit affect the volume outcome association. PMID- 29454999 TI - Long-term treatment with green tea polyphenols modifies the gut microbiome of female sprague-dawley rats. AB - Green tea polyphenols (GTP) have been shown to exert a spectrum of health benefits to animals and humans. It is plausible that the beneficial effects of GTP are a result of its interaction with the gut microbiota. This study evaluated the effect of long-term treatment with GTP on the gut microbiota of experimental rats and the potential linkage between changes of the gut microbiota with the beneficial effects of GTP. Six-month-old Sprague-Dawley rats were randomly allocated into three dosing regimens (0, 0.5%, and 1.5% of GTP) and followed for 6 months. At the end of month 3 or month 6, half of the animals from each group were sacrificed and their colon contents were collected for microbiome analysis using 16S ribosomal RNA and shotgun metagenomic community sequencing. GTP treatment significantly decreased the biodiversity and modified the microbial community in a dose-dependent manner; similar patterns were observed at both sampling times. Multiple operational taxonomic units and phylotypes were modified: the phylotypes Bacteroidetes and Oscillospira, previously linked to the lean phenotype in human and animal studies, were enriched; and Peptostreptococcaceae previously linked to colorectal cancer phenotype was depleted in GTP treated groups in a dose-dependent manner. Several microbial gene orthologs were modified, among which genes related to energy production and conversion were consistently enriched in samples from month 6 in a dose-dependent manner. This study showed that long-term treatment with GTP induced a dose dependent modification of the gut microbiome in experimental rats, which might be linked to beneficial effects of GTP. PMID- 29455001 TI - Evolution and molecular mechanism of PitAs in iron transport of Streptococcus species. AB - Iron is an essential element for almost all bacteria. The iron ATP-binding cassette (ABC) transporters located on the cell membrane affects bacterial virulence and infection. Although a variety of Fe3+-transporters have been found in bacteria, their evolutionary processes are rarely studied. Pneumococcal iron ABC transporter (PitA), a highly conserved Fe3+-transporter in most pathogenic bacteria, influences the capsule formation and virulence of bacteria. However, multiple sequence alignment revealed that PitA is expressed in four different variants in bacteria, and the structural complexity of these variants increases progressively. To more efficiently import Fe3+ ions into bacterial cells, bacteria have evolved a fused PitA from two separately expressed PitA-1 (SPD_0227) and PitA-2 (SPD_0226) proteins. Further biochemical characterization indicated that both PitA-1 and PitA-2 have weaker Fe3+-binding ability than their protein complex. More importantly, Glutathione S-Transferase (GST) pull-down and isothermal titration calorimetry (ITC) detection showed that PitA-1 and PitA-2 interact with each other via Tyr111-Leu37, Asn112-Gln38, Asn103-Leu33, and Asn103 Thr34. Further molecular dynamics (MD) simulations demonstrated that this interaction in full-length PitA is stronger than that in the two individual proteins. Deletion of PitA family genes could lead to decrease in the ability of iron acquisition and of adhesion and invasion of S. pneumoniae. Our study revealed the evolving state and molecular mechanism of Fe3+-transporter PitAs in bacteria and provided important information for understanding the iron transportation mechanism in bacteria and designing new antibacterial drugs. PMID- 29455002 TI - The possible neuroprotective effect of ellagic acid on sodium arsenate-induced neurotoxicity in rats. AB - OBJECTIVE: Arsenic is a well-known environmental contaminant, causing toxicity in different organs. The aim of this study was to investigate the possible neuroprotective effect of ellagic acid (EA) on arsenic-induced neurotoxicity in rats. DESIGN: Animals were divided into five groups. The first group received normal saline (2 mL/kg) for 21 days as control group. Group 2 was orally treated with sodium arsenite (SA, 10 mg/kg) for 21 days. Groups 3 and 4 were orally treated with SA (10 mg/kg) for 7 days prior to EA (10 and 30 mg/kg respectively) treatment and continued up to 21 days simultaneously with SA administration. Group 5 was orally treated with EA (30 mg/kg) for 14 days. Passive avoidance test and rotarod test were done to evaluate the behavioral changes following SA and/or EA treatment. Different biochemical, histological and molecular biomarkers were assessed in the brain tissue. RESULTS: Our data showed that SA significantly elevated brain tissue arsenic levels and malondialdehyde, nitric oxide, protein carbonylation, tumor necrosis factor-alpha, and interlukein-1beta production. A decrease in the total antioxidant capacity, reduced glutathione content and glutathione peroxidase activity occurred in the brain of rats exposed to SA. SA treated rats showed a significant impairment in long-term-memory, motor coordination and equilibrium. These results were supported by histopathological observations of the brain. Results revealed that administration of EA (30 mg/kg) reversed all neural markers alternation and ameliorated behavioral and histopathological changes induced by SA. CONCLUSION: EA can effectively protect brain tissue against SA-induced neurotoxicity via its antioxidant and anti inflammatory effects. PMID- 29455003 TI - Combinatorial strategy of epigenetic and hormonal therapies: A novel promising approach for treating advanced prostate cancer. AB - AIMS: Estrogens act as key factors in prostate biology, cellular proliferation and differentiation as well as cancer development and progression. The expression of estrogen receptor (ER)-beta appears to be lost during prostate cancer progression through hypermethylation mechanism. Epigenetic drugs such as 5-aza-2' deoxycytidine (5-AZAC) and Trichostatin A (TSA) showed efficacy in restoring ERbeta expression in prostate cancer cells. This study was designed to explore the potential anti-carcinogenic effects resulting from re-expressing ERbeta1 using 5-AZAC and/or TSA, followed by its stimulation with Diarylpropionitrile (DPN), a selective ERbeta1 agonist, in prostate cancer cell line PC-3. MAIN METHODS: Cells were treated with 5-AZAC, TSA, DPN and their combination. Subsequently, they were subjected to proliferation assays, determinations of ERbeta1 expression, protein levels of active caspase-3, cyclin D1, beta-catenin and VEGF. KEY FINDINGS: Treatment with these drugs exhibited an increase in ERbeta1 expression to different extents as well as active caspase-3 levels. Meanwhile, a significant reduction in cyclin D1, VEGF and beta-catenin levels was achieved as compared to the vehicle control group (p < 0.05). Interestingly, the triple combination regimen led to the most prominent anti-tumor responses in terms of increased apoptosis, reduced proliferation as well as angiogenesis. SIGNIFICANCE: The results support the notion that ERbeta1 acts as a tumor suppressor protein and suggest that sequential ERbeta1 expression and activation can offer significant anti-tumor responses. The study highlights that the strategy of merging epigenetic and hormonal therapies may be beneficial in treating advanced prostate cancer. PMID- 29455004 TI - Role of rho-kinase (ROCK) in tonic but not phasic contraction in the frog stomach smooth muscle. AB - AIMS: Rho/Rho-kinase (ROCK) signaling has extensively been shown to take part in mammalian smooth muscle contractions in response to diverse agents yet its role in the contraction of amphibian smooth muscle has not been investigated. Therefore, we aimed to explore any role of this pathway in the contractions of frog stomach smooth. MAIN METHODS: The strips were prepared and suspended in organ baths filled with Ringer solution. Changes in the circular strips of the frog stomach muscle length were recorded isotonically with a force transducer in organ baths. KEY FINDINGS: Carbachol (CCh) exerted both phasic and tonic contractions. In contrast, atropin abolished all types of contractions by CCh. The phasic contractions were suppressed by a Ca2+ channel blocker, nifedipine but not by the ROCK inhibitor, Y-27632. However, the tonic contractions were markedly attenuated by Y-27632. Selective M1 receptor blocker, pirenzepin, selective M3 receptor blocker and DAMP had no effects on CCh-elicited contractions. On the other hand, selective M2 receptor blocker, AF-DX suppressed all types of contractile activity by CCh. SIGNIFICANCE: These data suggest that M2 receptor activation could mainly mediate CCh-induced phasic and tonic contractions, and ROCK seems to be involved in the CCh-induced tonic but not phasic contractions of the frog stomach smooth muscle. PMID- 29455006 TI - Analysis of cardiac stem cell self-renewal dynamics in serum-free medium by single cell lineage tracking. AB - Cardiac colony forming unit-fibroblasts (cCFU-F) are a population of stromal cells residing within the SCA1+/PDGFRalpha+/CD31- fraction of adult mouse hearts, and which have functional characteristics akin to bone marrow mesenchymal stem cells. We hypothesise that they participate in cardiac homeostasis and repair through their actions as lineage progenitors and paracrine signaling hubs. However, cCFU-F are rare and there are no specific markers for these cells, making them challenging to study. cCFU can self-renew in vitro, although the common use of serum has made it difficult to identify cytokines that maintain lineage identity and self-renewal ability. Cell heterogeneity is an additional confounder as cCFU-F cultures are metastable. Here, we address these limitations by identifying serum-free medium (SFM) for growth, and by using cCFU-F isolated from PdgfraGFP/+ mice to record fate outcomes, morphology and PDGFRalpha expression for hundreds of single cells over time. We show that SFM supplemented with basic fibroblast growth factor, transforming growth factor-beta and platelet derived growth factor, enhanced cCFU-F colony formation and long-term self renewal, while maintaining cCFU-F potency. cCFU-F cultured in SFM maintained a higher proportion of PDGFRalpha+ cells, a marker of self-renewing cCFU-F, by increasing Pdgfra-GFP+ divisions and reducing the probability of spontaneous myofibroblast differentiation. PMID- 29455005 TI - Could curcumin protect the dendritic trees of the CA1 neurons from shortening and shedding induced by chronic sleep restriction in rats? AB - BACKGROUND AND OBJECTIVE: This study evaluated the effect of chronic sleep restriction (CSR) with or without curcumin (CUR) treatment on dendritic lengths and spines of the CA1 hippocampus using the virtual space-ball method. MATERIALS AND METHODS: Male rats were randomly submitted to nine groups, including distilled water, CUR (100 mg/kg/day), olive oil, CSR plus distilled water, CSR plus CUR, CSR plus olive oil, grid-floor plus distilled water, grid-floor plus CUR, and grid-floor plus olive oil groups. Sleep deficiency was imposed using the multi-platform box containing water for 18 h/day. In 21 days, animal's brains were prepared for stereological studies. RESULTS: The mean dendrite length in CA1 neurons was reduced by 39% (p < 0.05) while the density of stubby, thin, and mushroom spines reduced by 38%, 33% and 32%, respectively (p < 0.01), in the CSR + distilled water group compared to the distilled water group. Yet, CUR treatment in CSR-rats was found to protect the declined dendritic length as well as loss of stubby and mushroom but not thin spines. CONCLUSION: The estimated dendritic length using the virtual space-ball method revealed that chronic sleep restriction for 18 h/day over 21 days could induce shortening and shedding of the CA1 dendritic trees which could notably be protected by CUR. PMID- 29455007 TI - Embryoid body arrays: Parallel cryosectioning of spheroid/embryoid body samples for medium through-put analysis. AB - Three dimensional (3D) culture of mammalian cells is emerging as a powerful new tool to understand organogenesis as well as serve as models for diseases with implications for therapeutic evaluation. 3D cultures are referred to variously as spheroid, organoids or embryoid bodies. While many methods exist for large scale production of embryoid bodies or other spheroid cell aggregates, either at controlled sizes using microwell/micropatterned plates or uncontrolled sizes in suspension dishes, very few protocols exist for medium throughput analysis of differentiation at the histological level. We have developed a method which allows for parallel processing, sectioning and analysis of multiple 3D samples (e.g. fixed at different time points, treated with different drugs/growth factors, generated from different cell lines etc.) by double-embedding blocks in a larger array format. Our protocol has few barriers for use and requires only materials commonly found in any lab currently using embedding materials for cryosectioning. Sectioning in parallel allows histological techniques (such as histochemistry, immunostaining or in situ hybridisation) to be performed simultaneously on many samples on a single slide. This reduces slide to slide variation as well as requiring less reagents, fewer consumables with lower time and labour requirements when compared to individually embedded samples. PMID- 29455008 TI - Quantitative estimation of mercury intake by toxicokinetic modelling based on total mercury levels in humans. AB - Mercury is a toxic metal that can be disseminated into the environment from both natural and anthropogenic sources. Human exposure to the metal stems mainly from food, and more particularly from the consumption of fish and other seafoods. Examining dietary exposure and measuring mercury levels in body tissues are two ways of estimating exposure to mercury. In this study, we utilized a modelling system consisting of three linear toxicokinetic models for describing the fate of methyl mercury, inorganic mercury, and metallic mercury in the body, in order to estimate daily intake of mercury as measured through total mercury concentrations in the blood. We then compared the results stemming from our modelling system to those of the detailed semi-quantitative food frequency questionnaire (FFQ) of the Norwegian Fish and Game (NFG) Study, a project that focused on dietary mercury exposure. The results indicate that toxicokinetic modelling based on blood levels gave higher daily intake values of mercury compared to those of the FFQ. Furthermore, the former had a wider range of estimates than the latter. The properties of the toxicokinetic model or limitations in the dietary exposure assessment could be posited as reasons for the differences between the respective methods. Moreover, the results may have been influenced by sources of mercury exposure that cannot be described as dietary, such as amalgam fillings. PMID- 29455009 TI - Protecting an adult identity: A grounded theory of supportive care for young adults recently diagnosed with cancer. AB - BACKGROUND: For adolescents and young adults living in high-income countries cancer remains the most common disease-related death. Increasing survival rates and projected longevity are positive outcomes, although long-term consequences of cancer and/or its treatment will likely increase the global burden of cancer. In low and middle-income countries the impact and needs of young adults with cancer are largely unknown and require further attention. However, universal studies have revealed that cancer-related needs for this group are multifactorial, complex and largely unmet. In response to these findings, the body of work on supportive care for young adults with cancer is growing. Yet, there is no published research in the context of the United Kingdom, regarding the role young adults play in managing their supportive cancer care needs. OBJECTIVE: To explore the experience, purpose and meaning of supportive cancer care to young adults recently diagnosed with cancer. DESIGN, SETTING AND PARTICIPANTS: Using constructivist grounded theory, data were collected in one to one interviews with eleven young adults (seven women and four men aged 19-24 years) being treated for cancer in two English hospitals. Data were analyzed using open and focused coding, constant comparison, theoretical coding and memoing, and this enabled construction of a subjective theory. RESULTS: Young adults in this study interpreted cancer as an interruption to the events, experiences and tasks forming the biographical work of their adult identity. Data analysis led to the construction of the theory, 'protecting an adult identity: self in relation to a diagnosis of cancer in young adulthood'. This theory arose from three categories: fragility of self, maintaining self in an altered reality and mobilizing external resources. Young adults faced the loss of their early adult identity. Interpreting cancer as a temporary interruption, they sought to re-establish their identity by directly and indirectly managing their supportive care needs. CONCLUSIONS: These findings contribute to the understanding of young adults' desired purpose of supportive cancer care. There are also implications for how health and social care professionals provide supportive care interventions to meet the needs of this population. PMID- 29455010 TI - Long-Term Outcomes of Thoracic Endovascular Aortic Repair Focused on Bird Beak and Oversizing in Blunt Traumatic Thoracic Aortic Injury. AB - BACKGROUND: The acute aortic arch angle and narrow aortic diameter in young patients may lead to bird-beak configuration and excessive oversizing of the stent graft in thoracic endovascular aortic repair (TEVAR) for blunt traumatic thoracic aortic injury (BTTAI). Little is known about the association of these factors and complications in long-term follow-up. We evaluated the long-term outcomes in terms of complications, reinterventions, and survival, focusing on the effects of bird-beak configuration and oversizing. METHODS: This prospective cohort study included patients who underwent TEVAR for BTTAI in our department between October 1999 and January 2015. The main outcomes were migration, collapse, intragraft mural thrombus, reintervention, and survival and their association with oversizing and bird-beak configuration. RESULTS: Thirty-four patients were included. Median age was 36 years, and 21% were women. Mean graft oversizing was 19% (range: 8-27%) at the proximal end and 27% (range:, -20% to 50%) at the distal end. Mean follow-up was 98 months (12-198 months). Seven patients presented intragraft mural thrombus, one of whom developed an occlusive parietal thrombosis 1 year after the procedure. Four patients (9%) required reintervention: postoperative revascularization of the left subclavian artery in 2 cases and aortic reinterventions in 2 others. No migration or mortality was seen during follow-up. Bird-beak configuration was seen in 65%: the mean protrusion extension was 16 mm (standard deviation [SD]: 7.4 mm) and the mean angle was 51 degrees (SD: 16 degrees ). The association between the complications and bird beak was not statistically significant. Patients with complications had significantly higher proximal end oversizing (23%) than the group with no complications (17%) (P = 0.0007). CONCLUSIONS: TEVAR for BTTAI shows good results in the long-term follow-up. Complications in our series seemed related to proximal end oversizing. Thoracic stent grafts with a smaller diameter should be available in all trauma centers to avoid excessive oversizing. PMID- 29455011 TI - Hybrid Retrograde Celiac Artery Stenting for Acute Mesenteric Ischemia after Gastric Surgery. AB - BACKGROUND: Celiac artery (CA) occlusions/stenosis is infrequently associated with liver ischemia due to its unique vascularization, where portal vein provides about 75% of liver's perfusion. Collateral flow from gastroduodenal artery also provides, in most cases, enough blood supply to prevent ischemic hepatitis. In cases where these collateral pathways are compromised, severe liver ischemia can occur. METHODS: We present a case of acute mesenteric ischemia following gastric surgery that was treated with a hybrid retrograde CA stenting. RESULTS: We report a case of a 72-year-old male, who underwent gastric surgery for gastric cancer. On fourth postoperative day, he presented with acute abdomen, and on laparotomy, a partial duodenal suture dehiscence was found and suture closed. Owing to worsening of patient's clinical condition, with associated ischemic hepatitis, 2 days later, a computed tomography angiography was performed that showed a superior mesenteric artery (SMA) occlusion at its origin with an associated, severe, ostial stenosis of the CA. On laparotomy, irreversible visceral ischemia was found, which led to total colectomy, resection of 50 cms of small bowel, and splenectomy. Liver ischemia was also confirmed. Femoral access was used to try to cannulate the CA and cross its stenosis, without success. Taking advantage of the open abdomen, we then opted to place a 5F sheath in the splenic artery stump. From this retrograde approach, stenosis traversal was easy, and the CA was ballooned and stented with reperfusion of almost all the liver. Despite these efforts, patient died because of multiorganic failure, 8 days later. CONCLUSIONS: Ischemic hepatitis is a rare but serious complication of CA/SMA occlusive disease. Its occurrence is at increased risk after surgeries, where collateral flow is compromised. The endovascular treatment is currently the preferred approach to treat visceral arteries occlusive disease; however, antegrade CA cannulation can be tricky, and in an open abdomen scenario, retrograde approach from the splenic artery can be an additional resource. This case demonstrates the flexibility of endovascular techniques and that they can provide useful solutions even during open surgery. PMID- 29455012 TI - Deep Venous Thrombosis in a Patient with Duplication of the Common Iliac Vein. AB - A congenital abnormality of the inferior vena cava is said to be an anatomical risk factor for venous thromboembolism. In this report, we present a case of a patient with a left duplicated common iliac vein who developed a venous thromboembolism following total abdominal hysterectomy and bilateral salpingo oophorectomy. Only 2 items were risk factors for thromboembolism: age of >=40 years and open surgery duration of >=30 min; no congenital abnormalities of the inferior vena cava or thrombotic factors were observed. Thus, it was suspected that the duplicated common iliac vein could have caused the venous thromboembolism. PMID- 29455013 TI - Laser Recanalization of Central Venous Occlusion to Salvage a Threatened Arteriovenous Fistula. AB - Central venous occlusion is conventionally managed with balloon angioplasty, stent extension, or sharp recanalization. Here, we describe recanalization of a chronically occluded innominate vein using excimer laser after conventional techniques were unsuccessful. Patient clinical improvement and fistula patency have been sustained 2 years postintervention. This technique may provide new hemodialysis access options for patients who would not otherwise be candidates for hemodialysis access on the ipsilateral side of a central venous occlusion. PMID- 29455014 TI - Cilostazol Improves Wound Healing in Patients Undergoing Open Bypass for Ischemic Tissue Loss: A Propensity Score Matching Analysis. AB - BACKGROUND: Few reports have described the effects of medication on the wound healing of ischemic ulcers after revascularization. This study was conducted to investigate the effects of cilostazol on wound healing in patients who underwent infrainguinal bypass for ischemic tissue loss. METHODS: Two hundred sixty-three limbs undergoing de novo infrainguinal bypass for tissue loss from January 2004 to December 2015 were divided into 2 groups based on whether or not cilostazol was administered after surgery. The end point was wound healing. The 1-year outcomes of the groups were analyzed using the Kaplan-Meier method, and a propensity score matching analysis was performed to examine the effects of cilostazol on wound healing. In addition, the significant predictors were determined using a Cox proportional hazards regression analysis. RESULTS: Sixty one and 202 limbs were included in the cilostazol and non-cilostazol group, respectively. The cilostazol group showed superior wound healing to the non cilostazol group (cilostazol versus non-cilostazol, 1-year wound healing rate: 92% vs. 81%; median wound healing time: 45 vs. 78 days, P = 0.002). The results of the cilostazol group remained superior after a propensity score matching (cilostazol versus non-cilostazol, 1-year wound healing rate: 95% vs. 83%; median wound healing time: 45.5 vs. 57 days, P = 0.048). A Cox proportional hazards regression analysis indicated that foot infection, Rutherford classification, diabetes mellitus, coronary artery disease, angiosome, the administration of cilostazol, and graft patency were significant factors that influenced wound healing. CONCLUSIONS: The postoperative use of cilostazol help to promote wound healing after open surgery. PMID- 29455015 TI - Symptomatic Type B Intramural Aortic Hematoma as a Complication of Retrograde Right Common Iliac Artery Dissection. AB - PURPOSE: To report the endovascular treatment of a spontaneous iliac artery dissection (IAD) involving iliac bifurcation, complicated by a type B intramural aortic hematoma (IMH). CASE REPORT: A 38-year-old female patient came to our institution referring an acute ascending back pain. The angio computed tomography scan showed the presence of a retrograde right IAD with entry tear at the iliac bifurcation and a concomitant aortic IMH. After hypogastric embolization with a vascular plug, self-expanding stent graft was placed to cover the iliac entry tear. At 12 months, the patient was asymptomatic and the angio computed tomography scan showed the patency of the iliac graft without IMH. CONCLUSIONS: Endovascular treatment of spontaneous IAD is a safe and effective option in symptomatic patient complicated with type B IMH. PMID- 29455016 TI - Descending Aorta Rupture after Transcatheter Aortic Valve Embolization. AB - BACKGROUND: To report a case of rupture of the descending aorta after aortic migration during transcatheter aortic valve replacement (TAVR). METHODS: An 85 year-old man with a severe and symptomatic aortic stenosis underwent elective TAVR, which complicated with embolization into the ascending aorta. While repositioning into the descending aorta, the procedure complicated with aortic rupture. RESULTS: The patient required urgent thoracic intravalve stent-graft implantation (thoracic endovascular aortic repair [TEVAR]). Reintervention with other stent graft was required 2 days after initial procedure as proximal rupture was again diagnosed. Patient was discharged 50 days later because of other medical complications. He remains stable at 1 year of follow-up. CONCLUSIONS: TEVAR is a valid and safe option in the treatment of iatrogenic acute aortic rupture due to TAVR. PMID- 29455017 TI - Thrombectomy Devices in the Treatment of Acute Mesenteric Ischemia: Initial Single-Center Experience. AB - BACKGROUND: To report our preliminary experience with endovascular revascularization of patients with acute mesenteric ischemia (AMI), using thrombectomy devices. METHODS: It is a retrospective analysis of patients admitted to our hospital due to AMI and who were subjected to concomitant or exclusive endovascular treatment, from January 2011 to January 2016. Patients were admitted at the emergency department, underwent imaging investigation, and were referred to the endovascular specialist. Endovascular treatment was performed through left brachial artery access and selective catheterization and thrombectomy with a 6F Rotarex Debulking Device (Straub Medical, Wangs, Switzerland). Laparotomy was performed based on clinical and radiologic sings and at the discretion of the surgeon. Demographic, clinical/periprocedural, postoperative, complication, and adjunct intervention data were reviewed. Technical success was defined as recanalization of the Riolan's arcade on angiographic control. RESULTS: Twenty patients (mean age: 69.8 +/- 11.3 years) underwent endovascular revascularization for AMI using thrombectomy devices, during the period of the study. Abdominal pain was the most common complain on admission (65%), with ileus (35%), sepsis (25%), and myocardial infarction as the main clinical referral presentation at admission. Fifteen patients (75%) had suggestive computer tomography (CT) signs of AMI on admission. Endovascular revascularization was successfully performed in all patients through the left brachial artery with a mean procedural time of 28 +/- 17 min. Superior mesenteric artery (SMA) was the main vessel involved in 75% on a solely basis. The majority of the SMA occlusions were in the periosteal (30%) and proximal to middle colic artery offspring (35%). Primary use of thrombectomy devices was performed in all patients, associated with balloon angioplasty (7/20; 50%), stent deployment (5/20; 25%), intraoperative selective thrombolysis (4/20; 20%) and catheter assisted aspiration in 10% (2/20) of patients. Average time between admission and computed tomography angiography was 1.5 +/- 0.5 hr, between admission and angiographic procedure was 2.5 +/- 1 hr, and between admission and surgery was 9 +/- 5 hr. Following recanalization, 14 patients (70%) underwent open surgery. Laparotomy with intestinal resection (enterectomy, colectomy) and transit deviation was the most common procedure. Complications directly related to the endovascular procedure occurred in 2 patients, represented by self-limited small perforations. Overall 30-day mortality was 40% (n = 8). During the period of this study, no patient died as a result of complications related to the use of rotational thrombectomy. CONCLUSIONS: Endovascular treatment of the AMI with the use of thrombectomy devices proved to be technically feasible and reasonably fast procedure. Early diagnosis and adequate treatment remains the cornerstone of the treatment. Early surgical evaluation and close integration between surgical and endovascular specialists are crucial to faster treatment and consequently lower extensive surgical resections and mortality. Further studies are necessary on this field to confirm these findings. PMID- 29455018 TI - Acute Massive Pulmonary Thromboembolism Treated by Selective Catheter-Directed Thrombolysis. AB - BACKGROUND: To evaluate the safety and efficacy of selective catheter-directed thrombolysis (SCDT) in treating acute massive pulmonary thromboembolism (AMPTE). METHODS: Twenty-six AMPTE patients were enrolled between March 2010 and March 2013. A Uni*Fuse infusion system was inserted into the main pulmonary artery thrombus. The thrombolytic regimen included an intraoperative bolus injection of 250,000 IU urokinase, followed by continuous thrombolytic infusion of 5,000 IU/kg per (every) 24 hr urokinase for 72 hr postoperatively. Clinical symptoms, shock index (SI), systolic pulmonary artery pressure (sPAP), peripheral arterial partial pressure of oxygen (PaO2), and Miller index (MI) were assessed before and after treatment. RESULTS: The patients included 16 men and 10 women (49.9 +/- 18.8 years old; time to onset of 50.2 +/- 28.5 hr). After thrombolysis, dyspnea and cough were relieved to varying degrees; chest pain, hemoptysis, and syncope disappeared. Importantly, a clinical success rate of 100% was achieved. All objective indices were improved: SI decreased from 1.74 +/- 0.38 before operation to 0.71 +/- 0.09 postoperatively (P = 0.00); PaO2 increased from 52.78 +/- 6.92 mm Hg to 85.98 +/- 5.91 mm Hg (P = 0.00); sPAP was reduced from 65.19 +/- 8.22 mm Hg to 34.42 +/- 4.05 mm Hg (P = 0.00); MI dropped from 0.69 +/- 0.09 to 0.33 +/- 0.06 (P = 0.00). Mean total urokinase amounts were 1,298,000 IU for each patient. Postoperative complications included 2 cases of puncture-site hematoma (cured by pressure bandage) and 1 case of gastrointestinal hemorrhage (healed by conservative treatment without blood transfusion). CONCLUSIONS: SCDT may be considered a safe and efficacious treatment for AMPTE. PMID- 29455019 TI - Ocular Myasthenia Induced by Rivaroxaban in Patient with Deep Vein Thrombosis. AB - The non-vitamin K antagonist oral anticoagulant rivaroxaban is indicated in prevention and treatment of venous thromboembolism (VTE). A 60-year-old male patient complained of bilateral ptosis after administration of rivaroxaban for deep vein thrombosis (DVT). Myasthenia gravis (MG) was confirmed by positive serum antiacetylcholine receptor antibody test. No mediastinal thymoma was found. The ocular myasthenia reversed after discontinuing rivaroxaban treatment. Nevertheless, ptosis recurred and chronic oral pyridostigmine bromide treatment was necessary. The mechanism of MG development by rivaroxaban therapy is not completely understood. The development of rivaroxaban-induced autoimmune disease could be based on cross-reactivity between antibodies against rivaroxaban-derived antigens or by T-cell activation. To our knowledge, this report of ocular myasthenia by rivaroxaban administration is the first in the literature. Despite the benefits of rivaroxaban, it is important to recognize unexpected immune related adverse events. PMID- 29455020 TI - Bayesian networks of age estimation and classification based on dental evidence: A study on the third molar mineralization. AB - Not only does the Bayesian approach offer a rational and logical environment for evidence evaluation in a forensic framework, but it also allows scientists to coherently deal with uncertainty related to a collection of multiple items of evidence, due to its flexible nature. Such flexibility might come at the expense of elevated computational complexity, which can be handled by using specific probabilistic graphical tools, namely Bayesian networks. In the current work, such probabilistic tools are used for evaluating dental evidence related to the development of third molars. A set of relevant properties characterizing the graphical models are discussed and Bayesian networks are implemented to deal with the inferential process laying beyond the estimation procedure, as well as to provide age estimates. Such properties include operationality, flexibility, coherence, transparence and sensitivity. A data sample composed of Italian subjects was employed for the analysis; results were in agreement with previous studies in terms of point estimate and age classification. The influence of the prior probability elicitation in terms of Bayesian estimate and classifies was also analyzed. Findings also supported the opportunity to take into consideration multiple teeth in the evaluative procedure, since it can be shown this results in an increased robustness towards the prior probability elicitation process, as well as in more favorable outcomes from a forensic perspective. PMID- 29455022 TI - Adaptive pathway development for Fabry disease: a clinical approach. AB - Fabry disease (FD) is a rare X-chromosome-linked lysosomal storage disorder. Although initial expectations of enzyme replacement therapy (ERT) were high, it is now clear that real-world effectiveness is disappointing and evidence gathering has been inadequate. In retrospect, development of ERT for FD had several shortcomings. Little convincing evidence on the effectiveness existed at time of authorization. Also, post-marketing evaluation failed to generate sufficient and relevant data for adequate evaluation on effectiveness. Adaptive pathways might have benefitted ERT development by: (i) involving healthcare professionals, patients, health technology assessment bodies and payers in the development process; (ii) iterative development, starting with initial authorization in classical males; (iii) a clear real-world data collection plan; (iv) an independent disease registry; and (v) prescription control. PMID- 29455021 TI - Effect of dopamine receptor D4 (DRD4) haplotypes on general psychopathology in patients with eating disorders. AB - Among the many candidate genes analyzed in eating disorder (ED) patients, those involved in dopaminergic functions may be of special relevance, as dopamine is known to play a significant role in feeding behavior, the distortion of body image, hyperactivity and reward and reinforcement processes. We aimed to determine the effect of functional polymorphisms and haplotypes in the Dopamine Receptor D4 (DRD4) gene on general psychopathological symptoms in ED patients. Two-hundred-and-seventy-three ED patients [199 with Anorexia Nervosa (AN) and 74 with Bulimia Nervosa (BN)] completed the SCL-90R inventory and were genotyped for four functional, clinically relevant DRD4 polymorphisms: three variants in the promoter region [120-bp tandem repeat (TR, long vs. short allele), C-616G and C 521 T] and a variable number of tandem repeats (VNTR) in exon 3 (7R vs. non-7R allele). After correcting for multiple testing, none of the assayed polymorphisms were individually associated with SCL-90R results. Four DRD4 haplotypes (*1-*4) were detected in the patients with a frequency > 0.1. In the BN group, haplotype *2 (non7R-TR long-C-C) was associated with higher scores in the three global SCL 90R indices (GSI, PSDI and PST) after Bonferroni correction (p <= 0.01 in all instances). Furthermore, carriers of this haplotype displayed higher scores (worst symptomatology) in Somatization, Obsessive-Compulsive, Anxiety, Phobic anxiety, Paranoid ideation and the test additional items (p-values for the differences between carriers vs. non-carriers ranging from 0.0001 to 0.0110). Certain combinations of DRD4 variants may contribute to psychopathological features in BN patients. PMID- 29455023 TI - An innovative paradigm of methods in microRNAs detection: highlighting DNAzymes, the illuminators. AB - miRNAs are short regulatory sequences that monitor gene expression at post transcriptional level. miRNAs play outstanding roles in cellular processes and their altered expression or aberrant function has been reported in diseases such as cancer. Furthermore, some of them serve as biomarkers for prognosis, diagnosis, and prediction of drug effectiveness as well as probable utility in the field of personalized medicine. As a result, proper and sensitive detection of miRNAs is a crucial matter. Traditional approaches including Northern blotting, Microarray, and Quantitative reverse transcription polymerase chain reaction have been extensively employed by means of miRNA detection for decades. However, these methods lack sufficient sensitivity, specificity and are labor intensive. In the recent years, DNAzyme-based assays have become strikingly attractive. The principal element in these techniques is a G-rich sequence, called the G-quadruplex, which turns into a DNAzyme with catalytic activity by addition of hemin, and subsequently allows simple and rapid detection of the target. In this review, different methods of miRNA detection, along with related advantages and disadvantages are discussed, with a special focus on DNAzymes and DNAzyme-derived methods. PMID- 29455024 TI - All-carbon suspended nanowire sensors as a rapid highly-sensitive label-free chemiresistive biosensing platform. AB - Nanowire sensors offer great potential as highly sensitive electrochemical and electronic biosensors because of their small size, high aspect ratios, and electronic properties. Nevertheless, the available methods to fabricate carbon nanowires in a controlled manner remain limited to expensive techniques. This paper presents a simple fabrication technique for sub-100 nm suspended carbon nanowire sensors by integrating electrospinning and photolithography techniques. Carbon Microelectromechanical Systems (C-MEMS) fabrication techniques allow fabrication of high aspect ratio carbon structures by patterning photoresist polymers into desired shapes and subsequent carbonization of resultant structures by pyrolysis. In our sensor platform, suspended nanowires were deposited by electrospinning while photolithography was used to fabricate support structures. We have achieved suspended carbon nanowires with sub-100 nm diameters in this study. The sensor platform was then integrated with a microfluidic chip to form a lab-on-chip device for label-free chemiresistive biosensing. We have investigated this nanoelectronics label-free biosensor's performance towards bacterial sensing by functionalization with Salmonella-specific aptamer probes. The device was tested with varying concentrations of Salmonella Typhimurium to evaluate sensitivity and various other bacteria to investigate specificity. The results showed that the sensor is highly specific and sensitive in detection of Salmonella with a detection limit of 10 CFU mL-1. Moreover, this proposed chemiresistive assay has a reduced turnaround time of 5 min and sample volume requirement of 5 uL which are much less than reported in the literature. PMID- 29455025 TI - Dual nanoenzyme modified microelectrode based on carbon fiber coated with AuPd alloy nanoparticles decorated graphene quantum dots assembly for electrochemical detection in clinic cancer samples. AB - The development of high-efficient technologies for cancer biomarkers detection has attracted tremendous research effort for its great clinic significance. In this work, we designed a new type of flexible and robust nanohybrid microelectrode by modifying carbon fiber with dual nanoenzyme, i.e., AuPd alloy nanoparticles (AuPd-ANPs) decorated graphene quantum dots (GQDs) assembly, and explored its practical application in electrochemical sensing system for sensitive detection of cancer biomarker hydrogen peroxide (H2O2) in human breast cancer cells and tissue. For the preparation of dual nanoenzyme modified microelectrode, ionic liquid was used as the electrolyte for the effective electrodeposition of GQDs on carbon fiber substrate to form a close-packed assembly under a very negative potential, then the highly dense AuPd-ANPs were uniformly decorated on GQDs assembly by electrodeposition. In virtue of the structural merits and synergistic contribution of dual nanoenzyme in enhancing the electrocatalytic activity to H2O2, the resultant nanohybrid microelectrode exhibited good sensing performances for electrochemical detection of H2O2, including a high sensitivity of 371 MUA cm-2 mM-1, a wide linear range from 1.0 MUM to 18.44 mM, a low detection limit of 500 nM (a signal-to-noise ratio of 3:1), as well as good selectivity and biocompatibility, which could be used for real-time tracking H2O2 released from different types of human breast cells and in situ sensitive detection of H2O2 in clinical breast cancer tissue. PMID- 29455026 TI - An approach for cell viability online detection based on the characteristics of lensfree cell diffraction fingerprint. AB - To overcome the drawbacks such as low automation and high cost, an approach for cell viability online detection is proposed, based on the extracted lensfree cell diffraction fingerprint characteristics. The cell fingerprints are acquired by a constructed large field-of-view (FOV) diffraction imaging platform without any lenses. The approach realizes distinguishing live and dead cells online and calculating cell viability index based on the number of live cells. With theoretical analysis and simulation, diffraction fingerprints of cells with different morphology are simulated and two characteristics are discovered to be able to reflect cell viability status effectively. Two parameters, fringe intensity contrast (FIC) and fringe dispersion (FD), are defined to quantify these two characteristics. They are verified to be reliable to identify live cells. In a cytotoxicity assay of different methyl mercury concentration on BRL cells, the proposed approach is used to detect cell viability. MTT method is also employed and the results of correlational analysis and Bland-Altman analysis prove the validity of the proposed approach. By comparison, it can be revealed that the proposed approach has some advantages over other present techniques. Therefore it may be widely used as a cell viability measurement method in drug screening, nutritional investigation and cell toxicology studies. PMID- 29455027 TI - Electrochemical detection of influenza virus H9N2 based on both immunomagnetic extraction and gold catalysis using an immobilization-free screen printed carbon microelectrode. AB - Influenza is a viral infectious disease considered as a source of many health problems and enormous socioeconomic disruptions. Conventional methods are inadequate for in-field detection of the virus and generally suffer from being laborious and time-consuming. Thus, studies aiming to develop effective alternatives to conventional methods are urgently needed. In this work, we developed an approach for the isolation and detection of influenza A virus subtype H9N2. For this aim, two specific influenza receptors were used. The first, anti-matrix protein 2 (M2) antibody, was attached to iron magnetic nanoparticles (MNPs) and used for the isolation of the virus from allantoic fluid. The second biomolecule, Fetuin A, was attached to an electrochemical detectable label, gold nanoparticles (AuNPs), and used to detect the virus tacking advantage from fetuin-hemagglutinin interaction. The MNP-Influenza virus AuNP formed complex was isolated and treated by an acid solution then the collected gold nanoparticles were deposited onto a screen printed carbon electrode. AuNPs catalyzes the hydrogen ions reduction in acidic medium while applying an appropriate potential, and the generated current signal was proportional to the virus titer. This approach allows the rapid detection of influenza virus A/H9N2 at a less than 16 HAU titer. PMID- 29455028 TI - Novel electrochemical biosensor based on cationic peptide modified hemin/G quadruples enhanced peroxidase-like activity. AB - This work designed an artificial substrate peptide to synthesize peptide-hemin/G quadruplex (peptide-DNAzyme) conjugates. In addition to enhancing catalytic activity of hemin/G-quadruplex, the peptide could also be induced and cleaved by prostate specific antigen (PSA). It was the first report on peptide-DNAzyme conjugates in application of the peptide biosensor. The polyethyleneimine-reduced graphene oxide@hollow platinum nanotubes (PEI-rGO@PtNTs) nanocomposites were cast on the glassy carbon electrode in order to form the interface of biocompatibility and huge surface area for bioprobes immobilization. In absence of PSA, the peptide-DNAzyme conjugates retained intact on the surface of the electrode to produce a strong response signal. But in presence of PSA, the peptide-DNAzyme conjugates were destroyed to release electron mediators, resulting in dramatical decrease of the electrochemicl signal. Therefore, the method had high sensitivity and super selectivity with the limit of detection calculated as 2.0 fg/mL. Furthermore, the strategy would be promising to apply for other proteases by transforming the synthetic peptide module of target. PMID- 29455030 TI - The clinical significance and biological function of tropomyosin 4 in colon cancer. AB - Tropomyosin 4 (TPM4) has been found to be dys-regulated, and function as oncogene or anti-oncogene in human cancers. However, there was no report on the clinical significance and biological function of TPM4 in colon cancer. This study was designed to investigate the clinical value and biological function of TPM4 in colon cancer. Thus, we detected the TPM4 expression in colon cancer clinical samples, and conducted the gain-of-function in colon cancer cell lines. In our results, TPM4 mRNA and protein expressions were reduced in colon cancer tissues and cell lines compared with normal colon tissues and colon epithelial cell line, respectively. TPM4 protein low-expression was obviously associated with clinical stage, T classification (invasion depth), N classification (lymph node metastasis), distant metastasis and differentiation. Survival analysis showed low expression of TPM4 was an unfavorable independent prognostic factor for colon cancer patients. Moreover, the experiments in vitro suggested up-regulated TPM4 expression suppressed colon cancer cell migration, invasion and metastasis associated gene expression including MMP-2, MMP-9 and MT1-MMP, but had no effect on cell proliferation. In conclusion, TPM4 is associated with clinical progression in colon cancer patient and acts as a tumor suppressor in colon cancer cell. PMID- 29455029 TI - Heterogeneous patterns of brain atrophy in Alzheimer's disease. AB - There is increasing evidence showing that brain atrophy varies between patients with Alzheimer's disease (AD), suggesting that different anatomical patterns might exist within the same disorder. We investigated AD heterogeneity based on cortical and subcortical atrophy patterns in 299 AD subjects from 2 multicenter cohorts. Clusters of patients and important discriminative features were determined using random forest pairwise similarity, multidimensional scaling, and distance-based hierarchical clustering. We discovered 2 typical (72.2%) and 3 atypical (28.8%) subtypes with significantly different demographic, clinical, and cognitive characteristics, and different rates of cognitive decline. In contrast to previous studies, our unsupervised random forest approach based on cortical and subcortical volume measures and their linear and nonlinear interactions revealed more typical AD subtypes with important anatomically discriminative features, while the prevalence of atypical cases was lower. The hippocampal sparing and typical AD subtypes exhibited worse clinical progression in visuospatial, memory, and executive cognitive functions. Our findings suggest there is substantial heterogeneity in AD that has an impact on how patients function and progress over time. PMID- 29455031 TI - Whole-word frequency and inflectional paradigm size facilitate Estonian case inflected noun processing. AB - Estonian is a morphologically rich Finno-Ugric language with nominal paradigms that have at least 28 different inflected forms but sometimes more than 40. For languages with rich inflection, it has been argued that whole-word frequency, as a diagnostic of whole-word representations, should not be predictive for lexical processing. We report a lexical decision experiment, showing that response latencies decrease both with frequency of the inflected form and its inflectional paradigm size. Inflectional paradigm size was also predictive of semantic categorization, indicating it is a semantic effect, similar to the morphological family size effect. These findings fit well with the evidence for frequency effects of word n-grams in languages with little inflectional morphology, such as English. Apparently, the amount of information on word use in the mental lexicon is substantially larger than was previously thought. PMID- 29455032 TI - Sevoflurane for procedural sedation in critically ill patients: A pharmacokinetic comparative study between burn and non-burn patients. AB - BACKGROUND: Sevoflurane has anti-inflammatory proprieties and short lasting effects making it of interest for procedural sedation in critically ill patients. We evaluated the pharmacokinetics of sevoflurane and metabolites in severely ill burn patients and controls. The secondary objective was to assess potential kidney injury. METHODS: Prospective interventional study in a burn and a surgical intensive care unit; 24 mechanically ventilated critically ill patients (12 burns, 12 controls) were included. The sevoflurane was administered with an expired fraction target of 2% during short-term procedural sedation. Plasma concentrations of sevoflurane, hexafluoroisopropanolol (HFIP) and free fluoride ions were recorded at different times. Kinetic Pro (Wgroupe, France) was used for pharmacokinetic analysis. Kidney injury was assessed with neutrophil gelatinase associated lipocalin (NGAL). RESULTS: The mean total burn surface area was 36+/ 11%. The average plasma concentration of sevoflurane was 70.4+/-37.5mg.L-1 in burns and 57.2+/-28.1mg.L-1 in controls at the end of the procedure (P=0.58). The volume of distribution was higher (46.8+/-7.2 vs 22.2+/-2.50L, P<0.001), and the drug half-life longer in burns (1.19+/-0.28h vs 0.65+/-0.04h, P<0.0001). Free metabolite HFIP was higher in burns. Plasma fluoride was not different between burns and controls. NGAL did not rise after procedures. CONCLUSION: We observed an increased volume of distribution, slower elimination rate, and altered metabolism of sevoflurane in burn patients compared to controls. Repeated use for procedural sedation in burn patients needs further evaluation. No renal toxicity was detected. TRIAL REGISTRY NUMBER: ClinicalTrials.gov Identifier NCT02048683. PMID- 29455033 TI - Thromboprophylaxis for ambulatory surgery: Results from a prospective national cohort. AB - BACKGROUND: Venous thromboembolism (VTE) prophylaxis is not always part of the usual care of ambulatory surgery patients, and few guidelines are available. OBJECTIVES: To collect data on the application of VTE prophylaxis in ambulatory patients. DESIGN: The OPERA study is a large national survey performed in 221 healthcare facilities. PATIENTS: Among patients, 2174 who underwent one of ten selected procedures over two pre-defined days of investigation. MAIN OUTCOME MEASURES: Assessment and management of the postoperative VTE risk. RESULTS: The postoperative VTE risk was assessed as nil (4.1% of the physicians), low (74%) or moderate (20%). This risk was assessed as lower (71%) in ambulatory surgery as compared to conventional surgery. In most centres (94%), a personal patient history of VTE was recorded preoperatively, and in 72% a prophylaxis protocol was systematically applied but only 40% of the responding centres had a written protocol for VTE prophylaxis. The postoperative period (discharge at home) was covered by a VTE protocol for 75% of the centres, with VTE prophylaxis starting postoperatively in 21% of the patients. In these patients, different treatments were applied: below-knee compression stockings (25%); thigh-length compression stockings (21%); intermittent pneumatic compression in the recovery room (1.2%); unfractionated heparin (2.0%); low molecular weight heparins (65%); vitamin K antagonists (0.5%); other treatments, including direct oral anticoagulants (0.5%). CONCLUSION: These data underline the need for a better assessment of the VTE risk in ambulatory patients and new studies either with conventional or new agents to be able to build guidelines in this new setting. PMID- 29455034 TI - Preoperative risk factors for unexpected postoperative intensive care unit admission: A retrospective case analysis. AB - INTRODUCTION: The purpose of this retrospective case-control study was to investigate preoperative risk factors for unexpected postoperative intensive care unit (ICU) admissions in patients undergoing non-emergent surgical procedures in a tertiary medical centre. METHODS: A medical record review of adult patients undergoing elective non-cardiac and non-transplant major surgical procedures during the period of January 2011 through December 2015 in the operating rooms of a large university hospital was carried out. The primary outcome assessed was unexpected ICU admission, with mortality as a secondary outcome. Demographic data, length of hospital and ICU stay and preoperative comorbidities were also obtained as exposure variables. Propensity score matching was then employed to yield a study and control group. RESULTS: The group of patients who met inclusion criteria in the study and the control group that did not require ICU admission were obtained, each containing 1191 patients after propensity matching. Patients with acute and/or chronic kidney injury (odds ratio (OR) 2.20 [1.75-2.76]), valvular heart disease (OR: 1.94 [1.33-2.85]), peripheral vascular disease (PVD) (OR: 1.41 [1.02-1.94]) and congestive heart failure (CHF) (OR: 1.80 [1.31-2.46]) were all associated with increased unexpected ICU admission. History of cerebrovascular accident (CVA) (OR: 3.03 [1.31-7.01]) and acute and/or chronic kidney injury (OR: 1.62 [1.12-2.35]) were associated with increased mortality in all patients; CVA was also associated with increased mortality (OR: 3.15 [1.21 8.20]) specifically in the ICU population. CONCLUSIONS: CHF, acute/chronic kidney injury, PVD and valve disease were significantly associated with increased unexpected ICU admission; patients with CVA suffered increased mortality when admitted to the ICU.

AB - BACKGROUND: Sustainability of ERP is a challenge and data are scarce on the subject. The aim of this study was to assess if application of enhanced recovery elements through the Francophone Group of Enhanced Recovery after Surgery (Grace) in the anaesthesia management was sustainable 2 years after its implementation. MATERIALS AND METHODS: We conducted a retrospective analysis of the prospective Grace database between October 2014 and October 2016. The evolution of each recommendation item over time was analysed using non-parametric Spearman correlation coefficient. RESULTS: A total of 67 and 43 centres corresponding to 2067 and 3022 patients participated to the Grace audit in colorectal and orthopaedics surgery, respectively. Colorectal surgery: Mean length of stay was 5 (+/-4) days and readmission rate was 6.6%. Application of most items did not statistically change. It worsened over time for PONV prophylaxis (P=0.01) and prevention of intraoperative hypothermia (P=0.02); and improved for NSAID administration (P=0.01). Orthopaedics surgery: Mean length of stay was 3 (+/-2) days and readmission rate was 1.7%. There was a trend towards improvement for most items. It reached statistical significance for PONV prophylaxis (P=0.001), limited preoperative fasting (P=0.01). While the use of a perineural catheter (P=0.001) decreased over time, infiltration of the surgical site statistically increased (P=0.05). CONCLUSION: This study shows on a large scale a trend towards less application of all ERP items over time. Continuous audits should be encouraged to expect further improvements.

AB - BACKGROUND: Sacrocolpopexy (SC) involves suspension of the vaginal vault or cervix to the sacrum using a mesh. Following insertion, the meshes have been observed to have undergone dimensional changes. OBJECTIVE: To quantify dimensional changes of meshes following implantation and characterize their morphology in-vivo. DESIGN SETTING AND PARTICIPANTS: 24 patients underwent SC using PolyVinyliDeneFluoride mesh loaded with Fe3O4 particles. Tailored anterior and posterior mesh flaps were sutured to the respective vaginal walls, uniting at the apex. The posterior flap continued to the sacrum and was attached there. Meshes were visualized on magnetic resonance (MR) imaging at 12 [3-12] (median [range]) months postoperatively and 3D models of the mesh were generated. Dynamic MR sequences were acquired during valsalva to record mesh mobility. OUTCOME MEASURES: The area of the vagina effectively supported by the mesh (Effective Support Area (ESA)) was calculated. The 3D models' wall thickness map was analyzed to identify the locations of mesh folding. Intraclass correlation (ICC) was calculated to test the reliability of the methods. To measure the laxity and flatness of the mesh, the curvature and the ellipticity of the sacral flap were calculated. RESULTS: The ESA calculation methodology had ICC = 0.97. A reduction of 75.49 [61.55-78.67] % (median [IQR]) in area, 47.64 [38.07-59.81] % in anterior flap, and of 23.95 [10.96-27.21] % in the posterior flap was measured. The mesh appeared thicker near its attachment at the sacral promontory (n = 19) and near the vaginal apex (n = 22). The laxity of the mesh was 1.13 [1.10-1.16] and 60.55 [49.76-76.25] % of the sacral flap was flat. We could not reliably measure mesh mobility (ICC = 0.16). CONCLUSION: A methodology for complete 3D characterization of SC meshes using MR images was presented. After implantation, the supported area is much lower than what is prepared prior to implantation. We propose this happened during the surgery itself.

AB - The aim of this study was to synthesize and characterize mesoporous materials SBA 15 and SBA-15 modified with 3-(methacryloxy)-propyl-trimethoxysilane (MPS) to be used as inorganic filler in restorative dental composites and adhesives, and evaluate the main physical-chemical properties of the resulting material. The SBA 15 and SBA-15/MPS were characterized by FTIR, BET and X-Ray and combined with TEGDMA, bis-GMA and commercial spherical silica to produce dental composites. Afterwards, the mesoporous materials were combined with TEGDMA, bis-GMA and HEMA to make adhesives. To compare the results, composites and adhesives containing only commercial spherical silica were investigated. Some physical-chemical properties such as degree of conversion (DC), flexural strength (FS) and modulus (FM), water sorption and solubility (Wsp and Wsl), specific area (BET), and the leachable components were evaluated. The SBA-15/MPS can be used to prepare dental restorative materials, with some foreseeable advantages compared with pure SBA-15 dental materials and with improved properties compared with commercial spherical silica dental materials. An important improvement was that the dental materials based on modified SBA-15 presented a reduction of approximately 60% in leaching of unreacted monomers extracted by solvent compared to the control group. PMID- 29455038 TI - Mechanical and degradation property improvement in a biocompatible Mg-Ca-Sr alloy by thermomechanical processing. AB - Magnesium-based alloys have attracted interest as a potential material to comprise biomedical implants that are simultaneously high-strength and temporary, able to provide stabilization before degrading safely and able to be excreted by the human body. Many alloy systems have been evaluated, but this work reports on improved properties through hot extrusion of one promising alloy: Mg-1.0 wt% Ca 0.5 wt%Sr. This alloy has previously demonstrated promising toxicity and degradation properties in the as-cast and rolled conditions. In the current study extrusion causes a dramatic improvement in the mechanical properties in tension and compression, as well as a low in vitro degradation rate. Microstructure (texture, second phase distribution, and grain size), bulk mechanical properties, flow behavior, degradation in simulated body fluid, and effect on osteoblast cyctotoxicity are evaluated and correlated to extrusion temperature. Maximum yield strength of 300 MPa (above that of annealed 316 stainless steel) with 10% elongation is observed, making this alloy competitive with existing implant materials. PMID- 29455039 TI - Comparison of different constitutive models to characterize the viscoelastic properties of human abdominal adipose tissue. A pilot study. AB - Knowing the mechanical properties of human adipose tissue is key to simulate surgeries such as liposuction, mammoplasty and many plastic surgeries in which the subcutaneous fat is present. One of the most important surgeries, for its incidence, is the breast reconstruction surgery that follows a mastectomy. In this case, achieving a deformed shape similar to the healthy breast is crucial. The reconstruction is most commonly made using autologous tissue, taken from the patient's abdomen. The amount of autologous tissue and its mechanical properties have a strong influence on the shape of the reconstructed breast. In this work, the viscoelastic mechanical properties of the human adipose tissue have been studied. Uniaxial compression stress relaxation tests were performed in adipose tissue specimens extracted from the human abdomen. Two different viscoelastic models were used to fit to the experimental tests: a quasi-linear viscoelastic (QLV) model and an internal variables viscoelastic (IVV) model; each one with four different hyperelastic strain energy density functions to characterise the elastic response: a 5-terms polynomial function, a first order Ogden function, an isotropic Gasser-Ogden-Holzapfel function and a combination of a neoHookean and an exponential function. The IVV model with the Ogden function was the best combination to fit the experimental tests. The viscoelastic properties are not important in the simulation of the static deformed shape of the breast, but they are needed in a relaxation test performed under finite strain rate, particularly, to derive the long-term behaviour (as time tends to infinity), needed to estimate the static deformed shape of the breast. The so obtained stiffness was compared with previous results given in the literature for adipose tissue of different regions, which exhibited a wide dispersion. PMID- 29455040 TI - A simple method for calculating the likelihood ratio in a kinship test using X chromosomal markers incorporating linkage, linkage disequilibrium, and mutation. AB - X-chromosomal short tandem repeats (X-STRs) are useful for personal identification and kinship tests. However, it has not yet been fully established how to incorporate linkage and linkage disequilibrium (LD) into the calculation of the likelihood ratio (LR). In this paper, we describe a simple calculation method of LR for X-STRs that incorporated linkage, LD, and mutations. Initially, Japanese population data of 27 X-STRs (DXS6807, DXS9902, DXS6795, DXS6810, DXS10076, DXS10077, DXS10078, DXS10162, DXS10163, DXS10164, DXS7132, DXS981, DXS6800, DXS6803, DXS6809, DXS6789, DXS6799, DXS7424, DXS101, DXS7133, GATA172D05, DXS10103, HPRTB, GATA31E08, DXS8377, DXS10147, and DXS7423) were collected from 748 unrelated individuals to estimate the influence of LD. Significant LD was observed on six pairs of loci. Subsequently, using the population data, a simulation study was performed to evaluate the validity of the present calculation method for LR in cases of father-daughter, full-sisters, paternal half-sisters, maternal half-sisters, and unrelated pairs of females (FD, FS, PHS, MHS, and UR, respectively). As a result, the distribution of LR among FD was completely separated from that among UR. In the sibship test, 98.6% of FS and 98.0% of PHS surpassed the maximum value of UR in combined LR. Even in the FS versus MHS setting, 60.5% of FS had a higher LR than any MHS. We conclude that the present model is powerful in discriminating the relationship and is able to obtain a reasonable LR with fewer computations. PMID- 29455041 TI - Is OSNA better than imprint cytology for intraoperative diagnosis of cancer involvement of axillary sentinel node in breast cancer? AB - OBJECTIVE: The study aim was to establish Sensitivity, Specificity, Positive Predictive Value, Negative Predictive Value (NPV), and Accuracy Values of both imprint cytology (IC) and the OSNA assay for intraoperative assessment of axillary sentinel node (SN) cancer involvement in breast cancer. Specifically, we wished to find out if true positive and false negative results of IC were associated to axillary lymphadenectomy (ALND). Also, we addressed a comparative cost analysis between techniques. METHODS: 244 patients treated for breast cancer in the Breast Unit of Hospital Germans Trias i Pujol from 2011 to 2015 were prospectively included. A transversal, consecutive design was applied to assess IC compared to the reference test (OSNA). Inclusion criteria were: T1 and T2 tumors with negative nodes, both clinically and on ultrasound. RESULTS: Sensitivity of IC for macrometastases was 70%. The NPV of IC for macrometastases was 95,75%. Accuracy of IC was 96,12%. In the comparative cost analysis, the release time of results for OSNA doubled that of IC and was associated with an increased cost of ? 370. CONCLUSIONS: IC has been stated as a good technique for intraoperative cancer involvement SN with high sensitivity and NPV compared to the OSNA assay. It allows keeping the whole node tissue and thus the possibility of improved histopathological evaluation, which can be useful for adjuvant, and offers the advantage of being less time consuming. Cost analysis shows a higher cost for OSNA, which may exceed the benefit of sorting out false negatives from IC. PMID- 29455042 TI - Trapping of 1,2-cyclohexadiene: A DFT mechanistic study on the reaction of 1,2 cyclohexadiene with olefins and nitrones. AB - The mechanistic aspects of cycloaddition reactions of 1,2-cyclohexadiene with olefins and nitrones have been investigated with DFT calculations. The results show that the cycloaddition reactions of 1,2-cyclohexadiene with olefins do not go through a concerted pathway (one-step mechanism) but rather a stepwise one involving the formation of a biradical intermediate which then closes to form final cycloadduct. Electron-withdrawing substituents on the 1,2-cyclohexadiene decrease the activation barrier of the biradical-forming step but increase the barrier of the product-forming step and product stability, while electron donating substituents on the 1,2-cyclohexadiene increase the barriers for both the biradical-forming step and the product-forming step but decrease the product stability. In the reaction of 1,2-cyclohexadiene with nitrones, the four pathways investigated have activation barriers within 1 kcal/mol of one another, the lowest being 10.45 kcal/mol and the highest 11.04 kcal/mol, indicating that these reactions are very unselective. Electron-withdrawing groups on the nitrone increase the stability of the resulting products whereas electron-donating group on the nitrone decrease the stability of the resulting products. The [3 + 2] cycloadduct proceeds to the formation of a more stable formal [5 + 2] cycloadduct if a phenyl substituent is present on the nitrogen of the nitrone. PMID- 29455043 TI - Ultra-early injection of low-viscosity cement in vertebroplasty procedure for treating osteoporotic vertebral compression fractures: A retrospective cohort study. AB - OBJECTIVE: To evaluate the clinical effect of ultra-early injection (before the phase of "tooth-paste-like") of low-viscosity cement in percutaneous vertebroplasty (PVP) for treating osteoporotic vertebral compression fractures (OVCFs). METHODS: Two hundred sixty-one patients who had PVP procedures with low viscosity cement (ultra-early injection: 145, normal injection: 135) were included from July 2010 to July 2016 in our hospital. Visual Analog Scale (VAS), Oswestry Disability Index (ODI), Cobb angle, cement leakage, and adjacent vertebral fractures were evaluated. The follow-up period was over 12 months. RESULTS: VAS 3.0 d after surgery was significantly reduced in the ultra-early injection group compared to that in the control group (P = 0.00), but no difference was found at the final follow-up (P = 0.53). Similar results were found for ODI. The Cobb angle in both groups was recovered after PVP (P < 0.05); however, in the control group, the Cobb angle at the final follow-up was significantly increased compared with that 3.0 d after surgery (P = 0.00). There was a significant difference in the Cobb angle between the two groups at the final follow-up (P = 0.00). Regarding cement leakage, there were no significant differences in terms of mild (P = 0.58), moderate (P = 0.68), or severe leakage (P = 0.52). Seven patients in the control group had adjacent vertebral fractures, but only one patient in the ultra-early injection group experienced adjacent fractures (P = 0.03). CONCLUSIONS: Ultra-early injection of low-viscosity cement during PVP procedures in the treatment of OVCFs not only quickly and significantly relieves pain, reduces the incidence of adjacent vertebral fractures, and prevents progressive kyphotic deformity, but also does not increase the risk of cement leakage when compared with that of the traditional injection procedure. PMID- 29455044 TI - Timing of surgical site infection and pulmonary complications after laparotomy. AB - BACKGROUND: Surgical site infection (SSI) and other postoperative complications are associated with high costs, morbidity, secondary surgery, and mortality. Many studies have identified factors that may prevent SSI and pulmonary complications, but it is important to know when they in fact occur. The aim of this study was to investigate the diagnostic timing of surgical site infections and pulmonary complications after laparotomy. MATERIAL AND METHODS: This is a secondary analysis of the PROXI trial which was a randomized clinical trial conducted in 1400 patients undergoing elective or emergent laparotomy. Patients were randomly allocated to either 80% or 30% perioperative inspiratory oxygen fraction. RESULTS: SSI or pulmonary complications were diagnosed in 24.2% (95% CI: 22.0% 26.5%) of the patients at a median of 9 days [IQR: 5-15] after surgery. Most common was surgical site infection (19.6%); median time 10 days after surgery [IQR: 7-18]. The corresponding figures for anastomotic leakage was 5.7%, 8 days [IQR: 6-10]; pneumonia 3.5%, 5 days [IQR: 3-9]; and respiratory failure 2.3%, 3 days [IQR: 1-8]. The oxygen allocation was not significantly related to time of diagnosis for postoperative surgical site infections or pulmonary complications. CONCLUSION: A high percentage of patients undergoing laparotomy develop a postoperative complication. This study adds new knowledge by identifying time intervals within which medical professionals should be aware of surgical site infections and pulmonary complications in order to initiate appropriate treatment of the patients. PMID- 29455045 TI - Impact of transvaginal modified sacrospinous ligament fixation with mesh for the treatment of pelvic organ prolapse-before and after studies. AB - BACKGROUND: Pelvic organ prolapse (POP) is a common disease in women. The aim of this research was to evaluate the safety, efficacy and complication of transvaginal modified sacrospinous ligament fixation with mesh using for the treatment of vaginal vault prolapse. MATERIALS AND METHODS: This was a prospective study including information from 60 symptomatic women with anterior apical pelvic floor prolapse. The patients underwent transvaginal modified sacrospinous ligament fixation combined with anterior vaginal wall mesh between May 2014 and Sep 2015. The perioperative data including clinical characteristic, operation time, blood loss, and surgical complications were collected at 1 year and 2 years. During a 2-year follow-up, the primary outcome evaluation included Pelvic organ prolapse Quantification system (POP-Q), Incontinence Quality of Life scale (I-QoL), the Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) and the Pelvic Floor Distress Inventory, short form 20 (PFDI-20). RESULTS: The mean follow-up time was 2 years (range 24-37 months). The patients' mean age was 66.75 +/- 6.44. Of 60 patients who were enrolled in this research, 26 patients had severe stress urinary incontinence (SUI). The mean operation time was 99.14 +/- 19.60 min and the mean estimated blood loss was 73.83 +/- 41.05 ml. The rate of anatomical success was 98.3% and one patient had a recurrence. The POP-Q point measurements were evaluated preoperatively and postoperatively (P < 0.001). Moreover, the quality of life and sexual activity were all improved postoperatively via I-QoL, PISQ-12 and PFDI-20 scores (P < 0.001). There was no injury to the rectum, bladder, major pelvic vessels and pudendal nerves. However, 18 patients had postoperative complications. CONCLUSIONS: This study showed that transvaginal modified sacrospinous ligament fixation with mesh might be performed easily and might be a safe surgery for elderly patients whose requirements for sexual life were relatively low. Further researches were required to investigate its long-term efficacy. PMID- 29455046 TI - Evaluation of surgical outcome in advanced age patients with developmental hip dysplasia. AB - BACKGROUND: This study aimed at determining the efficacy of the surgical treatment conducted on children with delayed presentation developmental dysplasia of the hip (DDH). The objective was to provide a good comparison of functional and radiographic outcomes and to determine various surgical treatment options. METHOD: In this study, we evaluated the results of 38 hips of 27 patients aged 4 years onset which had been operated due to DDH. Radiographic outcomes were evaluated by using acetabular index, CE angle, Tonnis and the Severin classification system. Clinical evaluation was made by using IOWA hip scores. Degenerative changes were evaluated according to Boyer and avascular necrosis according to Kalamchi-MacEwen criteria. RESULTS: The mean age of the patients at the operation time was 10 years 3 months (range: 4 years 3 months-30 years). While the mean acetabular index was 37.97 preoperatively, in the last follow-up it was 19.92. Thirty-six hips (94%) had an excellent and good outcomes, and two hips (%6) had a fair outcome with respect to the Severin criteria. The mean hip score with respect to IOWA was 93.736 (range: 75-98) and the rate of excellent and good outcomes was 98%. CONCLUSION: For the treatment of patients with DDH of late onset, a one-staged operative procedure is recommended. This method is applied successfully and enables us to achieve good clinical and radiographic results. PMID- 29455047 TI - Prospective cohort study of neoadjuvant therapy toxicity in the treatment of oesophageal adenocarcinoma. AB - BACKGROUND: Early studies investigating the benefits of neoadjuvant therapy in oesophageal cancer showed conflicting results, taking many years before a survival advantage was demonstrated in randomised trials. Gains are modest, limited by progressive disease and toxicity. This study aimed to investigate the relationship between neoadjuvant therapy-associated toxicity and clinical outcomes including survival in patients with potentially curable oesophageal adenocarcinoma. MATERIALS AND METHODS: A cohort of 286 patients undergoing neoadjuvant therapy followed by surgical resection at a single institution was identified from a prospective database. Adverse events from neoadjuvant therapy were recorded and graded. Patients were divided into two groups according to whether they suffered toxicity or not. Clinical outcomes including whether patients completed the neoadjuvant course, whether they proceeded to resection and overall survival, were compared between the groups. RESULTS: Neoadjuvant therapy-related toxicity was identified in 67/286 patients. 46 patients suffered severe, life-threatening or fatal adverse events. In patients with toxicity, 47% did not complete the chemotherapy course compared to 17% without toxicity, RR 2.7 (95%CI 1.7-4.4), (P < 0.001). In patients suffering toxicity, 17.9% failed to proceed to resection compared with 7.8% in those without toxicity, RR 2.3 (95%CI 1.2-4.6) P = 0.02. Median overall survival was shorter in patients suffering toxicity (20.7 months) compared to those without toxicity (37.8 months), P = 0.008. When patients failing to proceed to resection were excluded, median overall survival was shorter in patients suffering toxicity (26.2 months) compared with those without toxicity (47.8), P = 0.039. CONCLUSION: Neoadjuvant therapy-related toxicity is common and can have serious consequences including failure to complete chemotherapy cycles, a higher risk of not proceeding to surgical resection and poorer overall survival. Efforts should be made to reduce toxicity and research should aim to identify responders and factors predictive of toxicity. PMID- 29455048 TI - A clinical prediction score to determine surgical drainage of deep neck infection: A retrospective case-control study. AB - BACKGROUND: The objective of this retrospective study was to identify predictors of an abscess guaranteed to be surgically drained successfully in patients with deep neck infection (DNI). MATERIALS AND METHODS: We divided 97 consecutive patients with DNI into a drained group and a non-drained group. We then developed a clinical prediction score and validated it in 32 further patients. RESULTS: Significant predictors of successful surgical drainage (i.e., positive for pus) were rim enhancement on computed tomography, C-reactive protein, erythrocyte sedimentation rate, and the neutrophil to lymphocyte ratio. The estimated cut-off values (excluding rim enhancement, which is a yes/no parameter) were 41.25, 56.5, and 8.02, respectively, and the clinical prediction score for each of the four other factors was determined to be 2, 2, 3, and 3 points, respectively. The cut off score for the sum of these points was 6.5 and the scoring system had an accuracy of 87.5% in the validation group. CONCLUSION: Our clinical prediction scoring system can predict whether drainage is successful in patients with DNI. PMID- 29455049 TI - Poststroke epilepsy following transient unilateral middle cerebral and common carotid artery occlusion in young adult and aged F344 rats. AB - The mechanisms of injured brain that establish poststroke seizures and epilepsy are not well understood, largely because animal modeling has had limited development. The main objective of this study was to determine whether an arterial occlusion model of cortical stroke in young adult and aged rats was capable of generating either focal or generalized epileptic seizures within 2 months of lesioning. Four- and 20-month-old male Fischer 344 (F344) sham-operated controls and those lesioned by transient (3 h) unilateral middle cerebral artery (MCA) and common carotid artery (CCA) occlusion (MCA/CCAo) were studied by video EEG recordings up to 2 months post-procedure. The main findings were: 1) seizures (grade 3 and above) were recorded within 2 months in both young (4-month; 0.23/h) and aged (20-month; 1.93/h) MCA/CCAo rat groups; both MCA/CCAo rat groups had more seizures recorded than the respective control groups, i.e., no seizures in young controls and 0.52/h in old controls; 2) both age and infarction independently had effects on seizure frequency; however, there was no demonstrated interaction between the two factors; and 3) there was no difference in infarct volumes comparing 4- to 20-month-old MCA/CCAo animals. In addition, all lesioned and sham-operated animals demonstrated intermittent solitary myoclonic convulsions arising out of sleep. Morbidity and mortality of animals limited the extent to which the animals could be evaluated, especially 20-month old animals. These results suggest that transient unilateral MCA/CCAo can result in poststroke epileptic seizures in both young adult and aged F344 rats within a relatively brief period of time following lesioning.

PMID- 29455050 TI - Targeted gene panel and genotype-phenotype correlation in children with developmental and epileptic encephalopathy. AB - OBJECTIVE: We performed targeted gene-panel sequencing for children with developmental and epileptic encephalopathy (DEE) and evaluated the clinical implications of genotype-phenotype correlations. METHODS: We assessed 278 children with DEE using a customized gene panel that included 172 genes, and extensively reviewed their clinical characteristics, including therapeutic efficacy, according to genotype. RESULTS: In 103 (37.1%) of the 278 patients with DEE, 35 different disease-causing monogenic mutations were identified. The diagnostic yield was higher among patients who were younger at seizure onset, especially those whose seizures started during the neonatal period, and in patients with drug-resistant epilepsy. According to epilepsy syndromes, the diagnostic yield was the highest among patients with West syndrome (WS) with a history of neonatal seizures and mutations in KCNQ2 and STXBP1 were most frequently identified. On the basis of genotypes, we evaluated the clinical progression and seizure outcomes with specific therapeutic regimens; these were similar to those reported previously. In particular, sodium channel blockers were effective in patients with mutations in KCNQ2 and SCN2A in infancy, as well as SCN8A, and interestingly, the ketogenic diet also showed diverse efficacy for patients with SCN1A, CDKL5, KCNQ2, STXBP1, and SCN2A mutations. Unfortunately, quinidine was not effective in 2 patients with migrating focal epilepsy in infancy related to KCNT1 mutations. CONCLUSION: Targeted gene-panel sequencing is a useful diagnostic tool for DEE in children, and genotype-phenotype correlations are helpful in anticipating the clinical progression and treatment efficacy among these patients. PMID- 29455052 TI - An instrumental variables approach to assess the effect of class size reduction on student screen time. AB - An emerging area of research considers links between characteristics of the school setting and health. The existing small evidence base assessing the association between class size and health is inconclusive. This quasi experimental study uses an instrumental variables approach based on North Carolina's elementary class size reduction policy to assess the relationship between class size and student screen time. Specifically, data are from public school students in North Carolina, USA, who were in 3rd grade any time between fall 2005 and spring 2011. There was no association between class size and screen time (measured as recreational television and/or electronic device use), after accounting for grade size and school size, year fixed effects, and clustering at the school and district level. These findings suggest that, in statewide policy implementation settings, there may not be any immediate spillover benefits of class size reduction policies on student screen time. PMID- 29455053 TI - The becoming of methadone in Kenya: How an intervention's implementation constitutes recovery potential. AB - This analysis treats the recent introduction of methadone treatment in Kenya as a case of 'evidence-making intervention'. Using 30 qualitative interviews with people in receipt of methadone treatment in Nairobi, Kenya, methadone's becoming is treated as an effect of its narrative and material implementations. The interviews are shown to enact a narrative of methadone recovery potential towards normalcy beyond addiction. Such recovery potential is materialised in practice through social interactions wherein methadone's embodied effects are seen to be believed. Here, the recovering body affects others' recovery potential. In a context of competing claims about methadone's effects, including the circulation of doubt about experimenting with methadone treatment, embodied methadone effect helps moderate the multiverse of methadone knowledge. The material dynamics of methadone treatment delivery also affect its recovery potential, with the methadone queue enacting a rationing of recovery hope. Here, the experience of methadone's implementation loops back to a life with drugs. I conclude that there is a coexistence of potentiality and actuality, a 'methadone multiple', produced through its narrative and material implementations. PMID- 29455054 TI - Seco-labdane diterpenoids from the leaves of Callicarpa nudiflora showing nitric oxide inhibitory activity. AB - Nine previously undescribed seco-labdane diterpenoids, nudiflopenes A-I, were isolated from the leaves of Callicarpa nudiflora. Their structures were elucidated on the basis of extensive 1D and 2D NMR spectroscopic data analysis, and the absolute configurations of these compounds were established by the modified Mosher's method and experimental and calculated electronic circular dichroism spectra. Nudiflopenes A-I belong to the class of seco-labdane diterpenoids. All of the isolates showed inhibitory activities on lipopolysaccharide-induced nitric oxide (NO) production in murine microglial BV-2 cells. The possible mechanism of NO inhibition of some bioactive compounds was also investigated using molecular docking, which revealed interactions of bioactive compounds with the inducible nitric oxide synthase (iNOS) protein. PMID- 29455055 TI - Specificity of glycosaminoglycan-protein interactions. AB - Glycosaminoglycans (GAGs) interact with a variety of proteins with important functions in development and homeostasis. Most of these proteins bind to heparin in vitro, a highly sulfated GAG species, although heparan sulfate and/or chondroitin/dermatan sulfate are more frequent physiological ligands. Binding affinity and specificity are determined by charge distribution, mainly due to sulfate and carboxylate groups and by GAG chain conformation. Interactions may be nonspecific, essentially reflecting charge density or highly specific, dependent on rare GAG-structural features. Yet other GAG epitopes bind protein ligands with intermediate specificity and variable affinity. Studies of heparan sulfate biosynthesis point to stochastic but strictly regulated, cell-specific polymer modification. Together, these features allow for graded modulation of protein functional response. PMID- 29455056 TI - Bringing diffuse X-ray scattering into focus. AB - X-ray crystallography is experiencing a renaissance as a method for probing the protein conformational ensemble. The inherent limitations of Bragg analysis, however, which only reveals the mean structure, have given way to a surge in interest in diffuse scattering, which is caused by structure variations. Diffuse scattering is present in all macromolecular crystallography experiments. Recent studies are shedding light on the origins of diffuse scattering in protein crystallography, and provide clues for leveraging diffuse scattering to model protein motions with atomic detail. PMID- 29455058 TI - Physical activity combined with resistance training reduces symptoms of frailty in older adults: A randomized controlled trial. AB - INTRODUCTION: Increased physical activity (PA) is a crucial factor in the prevention of physical deterioration, and resistance training (RT) is also a common and effective intervention for older adults. However, the effects of PA as an adjunct to RT on frailty status remains unclear; therefore, we clarified the effect of a PA intervention with feedback, as an adjunct to resistance strength training, on the physical and mental outcomes of frail older adults. MATERIALS AND METHODS: We employed a randomized controlled trial. Community-dwelling frail older adults in Japan were recruited to participate. Forty-one participants (mean age 81.5) were randomly assigned to engage in a resistance training with PA (RPA group) or RT group for six months. Frailty status and frailty scores, which were measured according to the Cardiovascular Health Study criteria-muscle strength, mobility, instrumental activities of daily living, and health-related quality of life-were assessed. RESULTS: Participants in the RPA group exhibited a significant increase in light-intensity PA, the number of steps taken daily (p < 0.05), and lower-limb muscle strength (p < 0.05) and a significant decrease in frailty scores. However, pre- and postintervention frailty status, instrumental activities of daily living, and health-related quality of life did not differ significantly. CONCLUSIONS: Implementation of a PA intervention as an adjunct to RT is feasible, as it reduced frailty scores and increased lower-limb muscle strength and mobility in older adults with frailty symptoms.

AB - The purpose of this study was to test a model of the factors influencing physical activity, physical function and physical performance at 2 months post hip fracture and compare model fit between men and women. Age, cognitive status, comorbidities, pain, resilience, bone mineral density, total body lean mass, total body fat and grip strength were hypothesized to be directly and/or indirectly related to physical activity, physical function and physical performance. This analysis used data from the seventh Baltimore Hip Studies (BHS 7), a prospective cohort study that included 258 community-dwelling participants, 125 (48%) men and 133 (52%) women, hospitalized for treatment of a hip fracture; survey and objective data were obtained at 2 months post hip fracture. In addition to age, sex and comorbidities (modified Charlson scale), data collection included body composition from dual-energy x-ray absorptiometry (DXA) scans, grip strength, and physical activity, function and performance based on the Yale Physical Activity Survey, the Short Physical Performance Battery and the Lower Extremity Gain Scale. Age, cognition, and comorbidities were not significantly associated with resilience; and, resilience was not associated with pain. In addition, bone mineral density was not associated with physical activity, physical performance or physical function. Total lean body mass, resilience and pain were associated with physical activity, physical function and physical performance in women, but were not consistently associated with physical and functional outcomes in men. Future research should consider evaluation of muscle quality and additional psychosocial factors (e.g., depression, social supports) in model testing. PMID- 29455060 TI - Major depressive disorder and depressive symptoms in intermittent explosive disorder. AB - It is estimated that between 1.7 and 2.6 million people have had intermittent explosive disorder (IED) during their life in the United States alone. Co occurring psychiatric disorders are very common in IED, being major depressive disorder arguably the most common. The objective of this study was to examine the clinical correlates of IED and depressive manifestations in 74 treatment-seeking subjects. After controlling for confounders, there were associations between major depressive disorder and severity of depressive symptoms, and (a) higher assault scores, (b) more severe hostile behavior and (c) worse social adjustment. Management of depressive symptoms may be an important for IED treatment. PMID- 29455059 TI - The impact of infection on mortality in octogenarians who were admitted due to acute coronary syndrome. AB - BACKGROUND: The prevalence of coronary artery disease is on the rise as the life expectancy of the population increases. However, treatment of acute coronary syndrome in the elderly patients has its own problems that have not been thoroughly addressed in the clinical trials. Since these patients are generally fragile and have multiple co-morbidities, the course of acute coronary syndrome can frequently be complicated. Infection, which co-exists either at the initial presentation or is acquired during the hospital stay, is a condition about which there is little published data. Therefore, in our study, we wanted to assess the impact of infection on mortality in octogenarians who have acute coronary syndrome METHODS: We retrospectively analyzed the data of 174 octogenarians who had been admitted to the coronary care unit with acute coronary syndrome. All cause mortality was defined as the primary endpoint of the study. RESULTS: Overall 53 octogenarian patients (30.5%) had an infection along with acute coronary syndrome. The mean duration of follow-up was 10 months (1-25 months). Both in-hospital and long-term mortality were higher in these patients (18.9% vs 6.6%, p = 0.01; 52.8% vs 27.5%, p < 0.01; respectively). Kaplan-Meier analysis also showed lower cumulative survival. (p [log-rank] = 0.002). In multivariate Cox regression analysis; undergoing coronary angiography, infection (HR 1.96, 95% CI 1.15-3.34, p = 0.01), left ventricular ejection fraction and maximum C reactive protein levels were found as independent predictors of long-term survival. CONCLUSION: Infection in octogenarians who were admitted due to acute coronary syndrome was frequent and increased their mortality substantially. PMID- 29455061 TI - Relationship between nurse staffing level and adult nursing-sensitive outcomes in tertiary hospitals of Korea: Retrospective observational study. AB - BACKGROUND: Nurse staffing level is an important factor on nursing sensitive outcome. The relationships of nurse staffing level with nursing sensitive outcomes such as mortality, upper gastrointestinal bleeding and pressure ulcer have been explored in the United States, Canada, Australia, and New Zealand. Lower level of hospital nurse staffing seems associated with more adverse outcomes, especially mortality. However, there is insufficient evidence of the nurse staffing level-outcome relationship in other indicators. OBJECTIVES: This study was conducted to describe the status and prove the relationships of nurse staffing level with nursing sensitive outcome indicators for adult medical and surgical inpatients in Korea. Patient and hospital characteristics as covariates on nurse sensitive outcome were also explored. DESIGN: This was a retrospective observational study. SETTING: The study setting was all 46 tertiary hospitals in Korea. PARTICIPANTS: We selected all anonymized patients aged 19 years or older and admitted at tertiary hospitals for two years (2013-2014) using electronic reimbursement claims data. METHOD: Multiple logistic regression was used to examine relationships of nurse staffing level (accounted for full-time registered nurses in general ward only) with Nursing-sensitive outcomes (NSOs) adjusted for patient and hospital characteristics. NSOs included urinary tract infection, upper gastrointestinal tract bleeding, deep vein thrombosis, hospital-acquired pneumonia, pressure ulcer, sepsis, shock/cardiac arrest, CNS complication, in hospital death, wound infection, physiologic/metabolic derangement and pulmonary failure. RESULTS: The total number of patients in 46 tertiary hospitals in Korea for two years was 3,665,307. Among these, number of patients who had at least one nursing-sensitive outcome was 338,369 (9.23%). The significant relationships of nurse staffing level with six nursing-sensitive outcome rates (urinary tract infection, upper gastrointestinal tract bleeding, hospital-acquired pneumonia, shock/cardiac arrest, in-hospital death, and wound infection) were shown. These six nursing-sensitive outcomes showed an increasing trend as nurse staffing level degraded even after adjusting for patient and hospital characteristics. When the nursing-sensitive outcomes between those of group 1 (bed-to-nurse ratio < 2:1) and group 3 (between 2.5:1 and 3:1) were compared, the adjusted incidence rate of shock/cardiac arrest showed the highest difference (1.06%). CONCLUSION: We demonstrated strong evidence for the relationships of nurse staffing level with six nursing-sensitive outcomes. We can use this study to improve nursing quality and to inform patients of the nursing quality of hospitals so they can choose hospitals with better nursing quality. The nurse staffing level should be optimized for better outcomes. PMID- 29455062 TI - Enhanced contraception of canine zona pellucida 3 DNA vaccine via targeting DEC 205 in mice. AB - Zona pellucida 3 (ZP3) is a potential antigen for the development of contraceptive vaccines to control animal population. In this study, we designed a canine ZP3 (CZP3) DNA vaccine through targeting DEC-205 (named as pcD-scFv-CZP3c) and investigated its contraceptive effect in mice. Female BALB/c mice were intramuscularly immunized 3 times at 2 weeks intervals. After immunization, humoral and cellular immune responses were detected by ELISA and flow cytometry. The results showed that pcD-CZP3 and pcD-scFv-CZP3c induced CZP3-specific antibody (Ab) responses both in serum and vaginal secretions compared to pcDNA3.1. Additionally, compared to pcD-CZP3, pcD-scFv-CZP3c increased the levels of CZP3-specific Abs after a third immunization. Abs induced by these two DNA vaccines could bind with mice and dogs oocytes. Moreover, pcD-scFv-CZP3c enhanced the activation of CD4+ T cells characterized by the increased frequencies of CD4+CD44+ T cells. Finally, the contraceptive effect was evaluated in the immunized mice. These two DNA vaccines significantly decreased a mean litter size of mice compared to pcDNA3.1, but pcD-scFv-CZP3c group showed the smallest mean litter size. The mean litter size of pcD-scFv-CZP3 were 3.2 +/- 0.742 and 4.6 +/- 1.118 in two mating tests, which were significantly lower than pcDNA3.1(P < 0.001 and P < 0.05). Our results suggest that the CZP3 DNA vaccine targeted with DEC 205 may be a potential strategy for developing a contraceptive DNA vaccine. PMID- 29455063 TI - An alanine residue in human parainfluenza virus type 3 phosphoprotein is critical for restricting excessive N0-P interaction and maintaining N solubility. AB - The phosphoprotein (P) of human parainfluenza virus type 3 (HPIV3) plays a pivotal role in viral RNA synthesis, which interacts with the nucleoprotein (N) to form a soluble N0-P complex (N0, free of RNAs) to prevent the nonspecific RNA binding and illegitimate aggregation of N. Functional regions within P have been studied intensively. However, the precise site (s) within P directly involved in N0-P interaction still remains unclear. In this study, using a series of deleted and truncated mutants of P of HPIV3, we demonstrate that amino-terminal 40 amino acids (aa) of P restrict and regulate N0-P interaction. Furthermore, using in vivo HPIV3 minigenome replicon assay, we identify a critical P mutant (PA28P) located in amino-terminal 40 aa, which fails to support RNA synthesis of HPIV3 minigenome replicon. Although PA28P maintains an enhanced N-P interaction, it is unable to form N0-P complex and keep N soluble, thus, resulting in aggregation and functional abolishment of N-P complex. Moreover, we found that recombinant HPIV3 with mutation of A28P in P failed to be rescued. Taken together, we identified a residue within the extreme amino-terminus of P, which plays a critical role in restricting the excessively N-P interaction and keeping a functional N0-P complex formation. PMID- 29455064 TI - The dynamics of both filamentous and globular mammalian reovirus viral factories rely on the microtubule network. AB - Mammalian reovirus viral factories (VFs) form filamentous or globular structures depending on the viral strain. In this study, we attempt to characterize the dynamics of both filamentous and globular VFs. Here, we present evidence demonstrating that globular VFs are dynamic entities coalescing between them, thereby gaining in size and concomitantly decreasing in numbers during the course of the infection. Additionally, both kinds of VFs condense into a perinuclear position. Our results show that globular VFs rely on an intact MT-network for dynamic motion, structural assembly, and maintenance and for perinuclear condensation. Interestingly, dynein localizes in both kinds of VFs, having a role at least in large globular VFs formation. To study filamentous VF dynamics, we used different transfection ratios of uNS with filamentous u2. We found a MT network dependency for VF-like structures perinuclear condensation. Also, uNS promotes VFLSs perinuclear positioning as well as an increase in acetylated tubulin levels. PMID- 29455065 TI - Foot-and-mouth disease virus type O specific mutations determine RNA-dependent RNA polymerase fidelity and virus attenuation. AB - Previous studies have shown that the FMDV Asia1/YS/CHA/05 high-fidelity mutagen resistant variants are attenuated (Zeng et al., 2014). Here, we introduced the same single or multiple-amino-acid substitutions responsible for increased 3Dpol fidelity of type Asia1 FMDV into the type O FMDV O/YS/CHA/05 infectious clone. The rescued viruses O-DA and O-DAMM are lower replication fidelity mutants and showed an attenuated phenotype. These results demonstrated that the same amino acid substitution of 3Dpol in different serotypes of FMDV strains had different effects on viral fidelity. In addition, nucleoside analogues were used to select high-fidelity mutagen-resistant type O FMDV variants. The rescued mutagen resistant type O FMDV high-fidelity variants exhibited significantly attenuated fitness and a reduced virulence phenotype. These results have important implications for understanding the molecular mechanism of FMDV evolution and pathogenicity, especially in developing a safer modified live-attenuated vaccine against FMDV. PMID- 29455067 TI - Gap-enhanced Raman tags for high-contrast sentinel lymph node imaging. AB - The sentinel lymph node (SLN) biopsy is gaining in popularity as a procedure to investigate the lymphatic metastasis of malignant tumors. The commonly used techniques to identify the SLNs in clinical practice are blue dyes-guided visualization, radioisotope-based detection and near-infrared fluorescence imaging. However, all these methods have not been found to perfectly fit the clinical criteria with issues such as short retention time in SLN, poor spatial resolution, autofluorescence, low photostability and high cost. In this study, we have reported a new type of nanoprobes, named, gap-enhanced Raman tags (GERTs) for the SLN Raman imaging. With the advantageous features including unique "fingerprint" Raman signal, strong Raman enhancement, high photostability, good biocompatibility and extra-long retention time, we have demonstrated that GERTs are greatly favorable for high-contrast and deep SLN Raman imaging, which meanwhile reveals the dynamic migration behavior of the probes entering the SLN. In addition, a quantitative volumetric Raman imaging (qVRI) data-processing method is employed to acquire a high-resolution 3-dimensional (3D) margin of SLN as well as the content variation of GERTs in the SLN. Moreover, SLN detection could be realized via a cost-effective commercial portable Raman scanner. Therefore, GERTs hold the great potential to be translated in clinical application for accurate and intraoperative location of the SLN. PMID- 29455066 TI - AAV8 virions hijack serum proteins to increase hepatocyte binding for transduction enhancement. AB - It has been demonstrated that human serum albumin (HSA) directly interacts with AAV virions and enhances AAV transduction. Several other proteins have also been identified a potential for enhancing AAV8 liver transduction. In our study, LDL or transferrin could enhance transduction in vitro and in vivo. We also found that any combination of two or three of these proteins (HSA, LDL, and transferrin) increased AAV8 transduction in Huh7 cells and in mice liver, which was similar to albumin alone. Pre-incubation of HSA with AAV8 virions prevented AAV8 virions from binding to other proteins. Furthermore, these serum protein receptors didn't impact AAV8 transduction but blocked the transduction enhancement from AAV8-serum protein complexes. These results indicate that serum proteins are hijacked by AAV8 vectors to increase hepatocyte binding, which shares same binding site. Importantly, the results could help us design an optimal formulation for effective AAV vector delivery in future clinical trials.

PMID- 29455069 TI - Photo-crosslinkable, injectable sericin hydrogel as 3D biomimetic extracellular matrix for minimally invasive repairing cartilage. AB - Millions of patients worldwide suffer from cartilage injury and age/disease related cartilage degeneration. However, cartilage, such as articular cartilage, is poor at self-regeneration. Current treatments are often invasive with limited efficacy. Developing minimal invasive strategies for effective cartilage repair is highly desired. Here, we report an injectable, photo-crosslinkable sericin hydrogel as a biomimetic extracellular matrix for minimal invasively repairing cartilage. Sericin was functionalized to be sericin methacryloyl (SerMA), which formed an in situ hydrogel upon UV light irradiation via photo-crosslinking. Possessing excellent biocompatibility, SerMA hydrogels were adhesive to chondrocytes, and promoted the proliferation of attached chondrocytes even in a nutrition-lacking condition. SerMA hydrogels exhibited photoluminescent property allowing real-time monitoring hydrogels' status. The mechanical properties and degradation rates (73% for SMH-1, 47% for SMH-2 and 37% for SMH-3 after 45 days) of SerMA hydrogels were readily tunable by varying methacryloyl modification degrees to meet various repair requirements. Notably, the in vivo implantation of chondrocyte-laden SerMA hydrogels effectively formed artificial cartilages after 8 weeks. Most importantly, the artificial cartilages molecularly resembled native cartilage as evidenced by high accumulation of cartilage-specific ECM components and upregulated expression of cartilage-critical genes. Together, this sericin hydrogel is a promising tissue engineering scaffold for generating artificial cartilage in vivo towards effective, minimal invasive cartilage repair. PMID- 29455070 TI - Oral engineered Bifidobacterium longum expressing rhMnSOD to suppress experimental colitis. AB - In recent years, using genetic engineering and bioengineering techniques, Bifidobacterium as a carrier to express specific functions of the protein or polypeptide, has become a new treatment for disease. Ulcerative colitis (UC) is a type of inflammatory bowel diseases (IBD). Although the cause of this inflammatory disorder is still unknown, a large amount of evidence suggests that ulcerative colitis is associated with increased activity of reactive oxygen species (ROS), manganese superoxide dismutase (MnSOD) is a kind of superoxide dismutase (SOD) has been demonstrated to play a key role in the pathophysiology of colitis. Here, we explored the Bifidobacterium as a drug delivery system to orally deliver a potent anti-inflammatory but poor penetration and stability antioxidant enzymes human MnSOD, transported into cells by a penetratin PEP-1. We constructed an expression vector expressing PEP-1-hMnSOD fusion protein, and successfully expressed hMnSOD fusion protein in engineered Bifidobacterium. Then we identified the bioactivity of engineered Bifidobacterium in LPS-induced inflammatory cell model. Finally, we used Bifidobacterium expressing PEP-1-hMnSOD fusion protein against DSS-induced ulcerative colitis mice. B. longum-PEP-1 rhMnSOD can successfully express rhMnSOD in the colon. We found that levels of inflammatory cytokines TNF-alpha, IL-1beta, IL-6 and IL-8 as well as histological damage in colonic tissues showed that engineered Bifidobacterium effectively reduced dextran sulfate sodium(DSS)-induced ulcerative colitis, we also tested the MPO, verified the above conclusions. These results suggest that oral Bifidobacterium expressing PEP-1-hMnSOD fusion protein can be treated as a new method of UC treatment. PMID- 29455071 TI - The use of satellite data to measure ultraviolet-B penetrance and its potential association with age of multiple sclerosis onset. AB - BACKGROUND: Studies have indicated an association between low Ultraviolet B (UVB) exposure and an increased risk of developing multiple sclerosis (MS). Few studies, however, have explored whether UVB exposure is associated with the age at MS symptom onset. OBJECTIVE: We investigated the potential association between cumulative early life ambient UVB exposure and age at MS onset, using satellite data to measure ambient UVB exposure. METHODS: Adult onset MS patients were selected from the University of British Columbia's MS genetic database (1980 2005). Patients' places of residence from birth to age 18 years were geocoded (latitude and longitude) and assigned UVB values using NASA's Total Ozone Mapping Spectrometer (TOMS) dataset. Linear regression was used to explore the relationship between cumulative UVB exposure (measured for age periods 0-6, 7-12, 13-18, 0-12, and 0-18) and age at MS onset. RESULTS: 3226 patients were included in the analysis. Of these, 74% were female, with an overall mean symptom onset age of 33.3 years. At onset, a total of 2944 (91%) had a relapsing-remitting disease course, 254 (8%) had primary progressive and the disease course for 28 (1%) was unknown. No significant associations between cumulative early life ambient UVB exposure and age at MS onset were observed. Patient sex, MS phenotype, and immigration to Canada after age 18 were significantly associated with age of onset (p < 0.01). CONCLUSIONS: Early life ambient UVB, as measured by satellite imagery, was not significantly associated with the age at MS onset.

PMID- 29455073 TI - Dimethyl fumarate in a patient with multiple sclerosis and type 1 diabetes mellitus: The importance of ketonuria. AB - BACKGROUND: Dimethyl fumarate (DMF) is approved for use in patients with relapsing-remitting multiple sclerosis (MS). Its mechanism of action is still not well understood, but besides the immunological pathways in MS, it may also affect the metabolism of normally functioning internal organs, tissues and cells. CASE PRESENTATION: We report on the case of 29-year-old woman with satisfactorily controlled type 1 diabetes (T1D), who was diagnosed as having MS. After administration of DMF she experienced intense, adverse gastro-intestinal reactions together with ketonuria up to 160 mg/dL. The highest ketone concentrations in the urine were observed approximately 2 h after each DMF dose and always with co-existing adverse reactions. Dose reduction did not improve symptoms and treatment had to be stopped. Twelve hours after the last dose of DMF all laboratory results returned to normal ranges and all gastro-intestinal adverse reactions were resolved within the following 24 h. CONCLUSION: This is a first report of ketonuria in a MS-patient with T1D treated with DMF. Patients with MS and co-existing metabolic diseases, which are not contraindicated for DMF treatment, represent a unique opportunity to address questions regarding the possible mechanisms of action of DMF on the cellular metabolism. The use of DMF in patients with metabolic diseases needs closer attention. PMID- 29455074 TI - The interplay of multiple sclerosis and menstrual cycle: Which one affects the other one? AB - BACKGROUND: Menstruation is suggested to affect multiple sclerosis (MS) symptoms, while the effect of MS on menstruation is not studied before. Here, we aimed to compare the pattern of menstrual cycle and its symptoms between MS patients and healthy controls. METHODS: This is a cross-sectional study conducted during 2015 2016 in MS clinic of Kashani hospital, Isfahan, Iran. We included female patients > 14 years with diagnosis of relapsing-remitting MS, and healthy subjects as the control group. We collected data regarding menarche age, menstrual characteristics, history of premenstrual syndrome, the amount of menstrual bleeding, and the possible perimenstrual symptoms from all subjects. Also, MS patients were asked to report changes in menstrual characteristics after MS occurrence. RESULTS: The final study population contained 181 MS patients and 202 healthy subjects. The mean age in MS and control group were 36.04 +/- 9.86 and 35.16 +/- 11.30, respectively (P-value = 0.426). Menarche age in MS patients and control group were not statistically different (13.59 +/- 1.87 and 13.29 +/- 1.53, respectively; P-value = 0.087). Changing menstrual characteristics was reported in 70 MS patients (38.7%). Irregular menstrual cycle increased from 21% to 40.3% after occurrence of MS (P-value < 0.001) and was reported 24.7% in the control group. MS patients versus controls reported more symptoms before, during, and after their menstrual period (P-values < 0.001). CONCLUSION: We found no difference regarding menstrual characteristics in MS patients before onset of the disease and healthy controls. Irregular menstrual cycle was observed more after the disease occurrence while other menstrual characteristics did not change. Moreover, MS patients reported many more perimenstrual symptoms. PMID- 29455075 TI - Prevalence of multiple sclerosis in Poland. AB - OBJECTIVE: The prevalence of multiple sclerosis (MS)was previously unknown in Poland. The aim of this study was to determine the prevalence of MS in Poland. METHODS: MS prevalence was determined on the basis of data from the Swietokrzyskie (central Poland) and Podlaskie (northeastern Poland) Voivodeships. The area population on the prevalence study day (December 31, 2013) was 1,268,239 (649,007 women; 619,232 men) in central and 1,195,625 (612,979 women; 582,646 men) in northeastern Poland. RESULTS: The overall crude prevalence rate of confirmed MS patients was 109.1/100,000 (95% confidence interval[CI]103.5-115.0) in the Swietokrzyskie and 108.7/100,000 (95% CI 103.0-114.7) in the Podlaskie Voivodeships. A significantly higher prevalence was recorded in females (149.8/100,000, 95% CI 140.6-159.3 vs. 142.4/100,000, 95% CI 133.3-152.0) than in males (66.5/100,000, 95% CI 60.4-73.1 vs.57.8/100,000, 95% CI 52.0-64.2)(p < 0.001). Age-adjusted rates for the Polish Standard Population were the same in both regions (110.3/100,000 (95% CI 104.6-116.1) vs.110.9/100,000 (95% CI 105.1 117.1)) and for the European Standard Population did not different statistically between both voivodeships (103.9/100,000 (95% CI 98.6-109.5) vs.108.5/100,000 (95% CI 102.7-114.5)). CONCLUSION: This is the first data that obtained the level of MS prevalence in Poland and confirmed that Poland is a high-risk area for multiple sclerosis. PMID- 29455076 TI - From child autistic symptoms to parental affective symptoms: A family process model. AB - BACKGROUND: Depression and anxiety are prevalent among parents of children with autism spectrum disorder (ASD), but limited research has investigated why parenting a child with ASD is associated with elevated distress and increased risks of mental health problems. We responded to this gap in the literature by examining the associations between child autistic symptoms and parental affective symptoms, as well as the potential underlying mechanisms. Guided by a family process theory, we hypothesized that child autistic symptoms would be positively associated with parental depressive and anxiety symptoms, and that these associations would be mediated by parents' concerns about their children's characteristics (future-related worry), parental roles (parenting stress), marital relationships (marital conflicts), and family conditions (family economic pressure). METHODS: Cross-sectional questionnaire data were collected from 375 parents of children with ASD residing in Hong Kong, China. The hypotheses were tested using structural equation modeling. RESULTS: Child autistic symptoms were positively associated with parental depressive and anxiety symptoms. These associations were mediated by future-related worry, parenting stress, marital conflicts, and family economic pressure. CONCLUSIONS: Our findings revealed the potential pathways through which child autism symptomatology may adversely affect parental mental health. Our findings also highlighted the importance of designing multipronged intervention programs for families raising children with ASD in order to improve relevant family processes and reduce parental affective symptoms.

AB - Adsorption or immobilization of proteins on synthetic surfaces is a key issue in the context of the biocompatibility of implant materials, especially those intended for the needs of cardiac surgery but also for the construction of biosensors or nanomaterials used as drug carriers. The subject of research was the analysis of Raman spectra of two types of fibrous carbon nanomaterials, of great potential for biomedical applications, incubated with human serum albumin (HSA). The first nanomaterial has been created on the layer of MWCNTs deposited by electrophoretic method (EPD) and then covered by thin film of pyrolytic carbon introduced by chemical vapor deposition process (CVD). The second material was formed from carbonized nanofibers prepared via electrospinning (ESCNFs) of polyacrylonitrile (PAN) precursor and then covered with pyrolytic carbon (CVD). The G-band blue-shift towards the position of about 1600cm-1, observed for both studied surfaces, clearly indicates the albumin (HSA) adhesion to the surface. The G and G' (2D) peak shift was employed to assess the stress build up on the carbon nanomaterials. The surface nano- and micro-topography as well as the method of ordering the carbon nanomaterial has a significant influence on the mode of surface-protein interaction. PMID- 29455078 TI - A supersensitive silver nanoprobe based aptasensor for low cost detection of malathion residues in water and food samples. AB - In the present study, we report a highly sensitive, rapid and low cost colorimetric monitoring of malathion (an organophosphate insecticide) employing a basic hexapeptide, malathion specific aptamer (oligonucleotide) and silver nanoparticles (AgNPs) as a nanoprobe. AgNPs are made to interact with the aptamer and peptide to give different optical responses depending upon the presence or absence of malathion. The nanoparticles remain yellow in color in the absence of malathion owing to the binding of aptamer with peptide which otherwise tends to aggregate the particles because of charge based interactions. In the presence of malathion, the agglomeration of the particles occurs which turns the solution orange. Furthermore, the developed aptasensor was successfully applied to detect malathion in various water samples and apple. The detection offered high recoveries in the range of 89-120% with the relative standard deviation within 2.98-4.78%. The proposed methodology exhibited excellent selectivity and a very low limit of detection i.e. 0.5pM was achieved. The developed facile, rapid and low cost silver nanoprobe based on aptamer and peptide proved to be potentially applicable for highly selective and sensitive colorimetric sensing of trace levels of malathion in complex environmental samples.

AB - Stereotactic treatments are today the reference techniques for the irradiation of brain metastases in radiotherapy. The dose per fraction is very high, and delivered in small volumes (diameter <1 cm). As part of these treatments, effective detection and precise segmentation of lesions are imperative. Many methods based on deep-learning approaches have been developed for the automatic segmentation of gliomas, but very little for that of brain metastases. We adapted an existing 3D convolutional neural network (DeepMedic) to detect and segment brain metastases on MRI. At first, we sought to adapt the network parameters to brain metastases. We then explored the single or combined use of different MRI modalities, by evaluating network performance in terms of detection and segmentation. We also studied the interest of increasing the database with virtual patients or of using an additional database in which the active parts of the metastases are separated from the necrotic parts. Our results indicated that a deep network approach is promising for the detection and the segmentation of brain metastases on multimodal MRI. PMID- 29455080 TI - Optimized multi-level elongated quinary patterns for the assessment of thyroid nodules in ultrasound images. AB - Ultrasound imaging is one of the most common visualizing tools used by radiologists to identify the location of thyroid nodules. However, visual assessment of nodules is difficult and often affected by inter- and intra observer variabilities. Thus, a computer-aided diagnosis (CAD) system can be helpful to cross-verify the severity of nodules. This paper proposes a new CAD system to characterize thyroid nodules using optimized multi-level elongated quinary patterns. In this study, higher order spectral (HOS) entropy features extracted from these patterns appropriately distinguished benign and malignant nodules under particle swarm optimization (PSO) and support vector machine (SVM) frameworks. Our CAD algorithm achieved a maximum accuracy of 97.71% and 97.01% in private and public datasets respectively. The evaluation of this CAD system on both private and public datasets confirmed its effectiveness as a secondary tool in assisting radiological findings.

AB - BACKGROUND: Few studies are focused on the quality of life (QOL) of primary caregivers and the effects of the clinical variables of epilepsy and patient psychiatric comorbidity on primary caregivers. PURPOSE: Our main objective was to describe QOL and level of burden (LB) in caregivers of people with epilepsy (PWE) at a tertiary-care hospital in Mexico City. A secondary purpose was to determine if LB and QOL were different between caregivers of patients with neuropsychiatric comorbidity and caregivers of patients without neuropsychiatric comorbidity. METHODS: One hundred and fifty-one caregivers of PWE were assessed with the short version of the World Health Organization Quality of Life (WHOQOL) scale (WHOQOL BREF) and the Zarit Burden Interview. Patients' clinical and demographic data, along with their psychiatric histories, were collected. RESULTS: One hundred and twelve patients had psychiatric comorbidity. The mean LB score of the caregivers was 26.25+/-16.28. The mean scores for the WHOQOL-BREF domains were as follows: physical health, 47.8+/-10.7; psychological health, 55.4+/-11.5; social relationships, 47.23+/-18.6; and environment, 48.7+/-11.6. The caregivers of patients with psychiatric comorbidity had lower scores in the domains of psychological health (p=0.034) and social relationships (p=0.029) compared with caregivers of PWE without comorbidity. On adjusted multivariate analysis, aggressiveness (p=0.008), age at onset of epilepsy (p=0.02), and years with epilepsy (p=0.01) were associated with higher caregiver LB scores; higher caregiver years of education were associated with better psychological health (p=0.002) and more years with epilepsy (p=0.03) with lower QOL scores. CONCLUSION: Aggressive behavior was the psychiatric comorbidity most clearly associated with lower QOL and higher LB. Longer duration of epilepsy was related to higher burden and lower QOL. More years of education of the caregiver were associated with better QOL. We found no significant correlation between seizure control and QOL or LB. PMID- 29455082 TI - Evaluating subjective cognitive impairment in the adult epilepsy clinic: Effects of depression, number of antiepileptic medications, and seizure frequency. AB - OBJECTIVE: Subjective cognitive complaints are a frequent concern of patients with epilepsy. The Aldenkamp-Baker Neuropsychological Assessment Schedule (ABNAS) is a patient-reported scale validated to measure adverse cognitive effects of antiepileptic drugs (AEDs). The goals of this study were to identify predictors of patient-reported cognitive dysfunction and to assess the relationship between subjective and objective cognitive impairment. METHODS: The Cleveland Clinic Knowledge Program Data Registry was used to identify adult patients seen in outpatient epilepsy clinic from January to May 2015 and who completed the following scales: ABNAS for subjective cognitive impairment, Patient Health Questionnaire (PHQ-9) for depression, Generalized Anxiety Disorder 7-item (GAD-7) scale, Quality of Life in Epilepsy (QOLIE-10), and EuroQOL five dimensions questionnaire (EQ-5D) for health-related quality of life. Topiramate (TPM) was considered a high-risk medication for cognitive impairment. Patients were categorized into groups based on total ABNAS score: subjective cognitive impairment (ABNAS>15; N=270) and no subjective cognitive impairment (ABNAS<=15; N=400). Multivariable logistic regression models were constructed to identify independent predictors of subjective cognitive impairment. In a subset of patients who had neuropsychological testing within 6months of completing the ABNAS (N=60), Pearson correlations and multivariable logistic regression models, controlling for number of AEDs, depression, and anxiety, assessed the relationship between subjective cognitive impairment and objective cognitive performance on measures of intelligence, attention/working memory, verbal fluency, naming, processing speed, manual dexterity, visuomotor processing, and verbal memory. RESULTS: Forty percent of patients in the overall sample (N=270/670) reported cognitive impairment. The variables most strongly associated with subjective cognitive impairment were PHQ-9 score, number of AEDs, and seizure frequency. In the subset of patients with neuropsychological testing, ABNAS score was correlated with anxiety (r=0.44), depression (r=0.38), and attention/working memory (r=-0.31). After adjusting for depression and anxiety, patients who endorsed subjective cognitive impairment scored significantly lower on measures of nonverbal intelligence and attention/working memory, but not on other cognitive measures. CONCLUSIONS: Subjective cognitive impairment as reported on the ABNAS is most strongly associated with depressive symptomatology, number of AEDs, and seizure frequency, but not with most objective cognitive measures. Identifying these three predictors provides a clear framework to understand and address subjective cognitive complaints in adult patients with epilepsy. PMID- 29455083 TI - A Single Domain-Based Anti-Her2 Antibody Has Potent Antitumor Activities. AB - Human epidermal growth factor receptor 2 (HER2) is overexpressed in approximately 20% to 30% of breast cancers and various other types of cancers, which plays a vital role in the cancer progression. Monoclonal antibodies targeting Her2 are now used in the clinic to treat Her2 overexpression cancer patients. However, relapse or resistance is frequent with the current therapies. To generate a new treatment avenue against Her2, we immunized and selected a specific anti-Her2 single domain antibody C3 for further studies. The C3-Fc antibody drove antibody dependent cell-mediated cytotoxicity against Her2-positive tumor cells in vitro and resulted in potent antitumor growth in vivo. These data suggest that the C3 Fc antibody may provide an alternative avenue for Her2-positive cancer therapy. PMID- 29455085 TI - Correlation of ADC With Pathological Treatment Response for Radiation Therapy of Pancreatic Cancer. AB - PURPOSE: To investigate the feasibility of using apparent diffusion coefficient (ADC) to assesspathological treatment response in pancreatic ductal adenocarcinoma (PDAC) following neoadjuvant chemoradiation (nCR). MATERIALS/METHODS: MRI and pathological data collected for 25patients with resectable and borderline resectable PDAC following nCR were retrospectively analyzed. Pre- and post-nCR mean ADC values in the tumors were compared using Wilcoxon matched pairs test. Correlation of pathological treatment response and ADC values was assessed using Pearson's correlation coefficient test and receiver operating-curve (ROC) analysis. RESULTS: The average mean and standard deviation (SD) of the ADC values for all the patients analyzed were significantly higher in post-nCR (1.667+/-0.161*10-3) compared with those prior to nCR (1.395+/-0.136*10 3 mm2/sec), (P<0.05). The mean ADC values after nCR were significantly correlated with the pathological responses (r=-0.5172); P=0.02. The area under the curve (AUC) of the ADC values for differentiating G1, G2 and G3 pathological responses, using ROC analysis, was found to be 0.6310 and P=0.03. CONCLUSION: Changes of pre and post-treatment ADC values significantly correlated with pathological treatment response for PDAC patients treated with chemoradiation therapy, indicating that the ADC could be used to assesstreatment response for PDAC. PMID- 29455084 TI - NHERF1 Between Promises and Hopes: Overview on Cancer and Prospective Openings. AB - Na+/H+ exchanger regulatory factor 1 (NHERF1) is a scaffold protein, with two tandem PDZ domains and a carboxyl-terminal ezrin-binding (EB) region. This particular sticky structure is responsible for its interaction with different molecules to form multi-complexes that have a pivotal role in a lot of diseases. In particular, its involvement during carcinogenesis and cancer progression has been deeply analyzed in different tumors. The role of NHERF1 is not unique in cancer; its activity is connected to its subcellular localization. The literature data suggest that NHERF1 could be a new prognostic/predictive biomarker from breast cancer to hematological cancers. Furthermore, the high potential of this molecule as therapeutical target in different carcinomas is a new challenge for precision medicine. These evidences are part of a future view to improving patient clinical management, which should allow different tumor phenotypes to be treated with tailored therapies. This article reviews the biology of NHERF1, its engagement in different signal pathways and its involvement in different cancers, with a specific focus on breast cancer. It also considers NHERF1 potential role during inflammation related to most human cancers, designating new perspectives in the study of this "Janus-like" protein. PMID- 29455086 TI - Combination of Pre-Treatment DWI-Signal Intensity and S-1 Treatment: A Predictor of Survival in Patients with Locally Advanced Pancreatic Cancer Receiving Stereotactic Body Radiation Therapy and Sequential S-1. AB - OBJECTIVE: To identify whether the combination of pre-treatment radiological and clinical factors can predict the overall survival (OS) in patients with locally advanced pancreatic cancer (LAPC) treated with stereotactic body radiation and sequential S-1 (a prodrug of 5-FU combined with two modulators) therapy with improved accuracy compared with that of established clinical and radiologic risk models. METHODS: Patients admitted with LAPC underwent diffusion weighted imaging (DWI) scan at 3.0-T (b = 600 s/mm2). The mean signal intensity (SIb = 600) of region-of-interest (ROI) was measured. The Log-rank test was done for tumor location, biliary stent, S-1, and other treatments and the Cox regression analysis was done to identify independent prognostic factors for OS. Prediction error curves (PEC) were used to assess potential errors in prediction of survival. The accuracy of prediction was evaluated by Integrated Brier Score (IBS) and C index. RESULTS: 41 patients were included in this study. The median OS was 11.7 months (2.8-23.23 months). The 1-year OS was 46%. Multivariate analysis showed that pre-treatment SIb = 600 value and administration of S-1 were independent predictors for OS. The performance of pre-treatment SIb = 600 and S-1 treatment in combination was better than that of SIb = 600 or S-1 treatment alone. CONCLUSION: The combination of pre-treatment SIb = 600 and S-1 treatment could predict the OS in patients with LAPC undergoing SBRT and sequential S-1 therapy with improved accuracy compared with that of established clinical and radiologic risk models. PMID- 29455087 TI - Isolation and characterization of biochar-derived organic matter fractions and their phenanthrene sorption. AB - Chemical composition and pollutant sorption of biochar-derived organic matter fractions (BDOMs) are critical for understanding the long-term environmental significance of biochar. Phenanthrene (PHE) sorption by the humic acid-like (HAL) fractions isolated from plant straw- (PLABs) and animal manure-based (ANIBs) biochars, and the residue materials (RES) after HAL extraction was investigated. The HAL fraction comprised approximately 50% of organic carbon (OC) of the original biochars. Results of XPS and 13C NMR demonstrated that the biochar derived HAL fractions mainly consisted of aromatic clusters substituted by carboxylic groups. The CO2 cumulative surface area of BDOMs excluding PLAB derived RES fractions was obviously lower than that of corresponding biochars. The sorption nonlinearity of PHE by the fresh biochars was significantly stronger than that of the BDOM fractions, implying that the BDOM fractions were more chemically homogeneous. The BDOMs generally exhibited comparable or higher OC normalized distribution coefficients (Koc) of PHE than the original biochars. The PHE logKoc values of the fresh biochars correlated negatively with the micropore volumes due to steric hindrance effect. In contrast, a positive relationship between the sorption coefficients (Kd) of BDOMs and the micropore volumes was observed in this study, suggesting that pore filling could dominate PHE sorption by the BDOMs. The positive correlation between the PHE logKoc values of the HAL fractions and the aromatic C contents indicates that PHE sorption by the HAL fractions was regulated by aromatic domains. The findings of this study improve our knowledge of the evolution of biochar properties after application and its potential environmental impacts. PMID- 29455088 TI - Parasite susceptibility in an amphibian host is modified by salinization and predators. AB - Secondary salinization represents a global threat to freshwater ecosystems. Salts, such as NaCl, can be toxic to freshwater organisms and may also modify the outcome of species interactions (e.g. host-parasite interactions). In nature, hosts and their parasites are embedded in complex communities where they face anthropogenic and biotic (i.e. predators) stressors that influence host-parasite interactions. As human populations grow, considering how anthropogenic and natural stressors interact to shape host-parasite interactions will become increasingly important. We conducted two experiments investigating: (1) the effects of NaCl on tadpole susceptibility to trematodes and (2) whether density- and trait-mediated effects of a parasite-predator (i.e. damselfly) and a host predator (i.e. dragonfly), respectively, modify the effects of NaCl on susceptibility to trematode infection. In the first experiment, we exposed tadpoles to three concentrations of NaCl and measured parasite infection in tadpoles. In the second experiment, we conducted a 2 (tadpoles exposed to 0 g L-1 NaCl vs. 1 g L-1 NaCl) x 4 (no predator, free-ranging parasite-predator (damselfly), non-lethal host-predator (dragonfly kairomone), and free-ranging parasite-predator + dragonfly kairomone) factorial experiment. In the absence of predators, exposure to NaCl increased parasite infection. Of the predator treatments, NaCl only caused an increase in parasite infection in the presence of the parasite-predator. However, direct consumption of trematodes caused a reduction in overall infection in the parasite-predator treatment. In the dragonfly kairomone treatment, a reduction in tadpole movement (i.e. trematode avoidance behavior) led to an increase in overall infection. In the parasite predator + dragonfly kairomone treatment, antagonistic effects of the parasite predator (reduction in trematode abundance) and dragonfly kairomone (reduction in parasite avoidance behavior) resulted in intermediate parasite infection. Collectively, these findings demonstrate that NaCl can increase amphibian susceptibility to parasites, and underscores the importance of considering predator-mediated interactions in understanding how contaminants influence host parasite interactions. PMID- 29455089 TI - Occurrence and transformation of veterinary antibiotics and antibiotic resistance genes in dairy manure treated by advanced anaerobic digestion and conventional treatment methods. AB - Manure treatment technologies are rapidly developing to minimize eutrophication of surrounding environments and potentially decrease the introduction of antibiotics and antibiotic resistant genes (ARGs) into the environment. While laboratory and pilot-scale manure treatment systems boast promising results, antibiotic and ARG removals in full-scale systems receiving continuous manure input have not been evaluated. The effect of treatment on ARGs is similarly lacking. This study examines the occurrence and transformation of sulfonamides, tetracyclines, tetracycline degradation products, and related ARGs throughout a full-scale advanced anaerobic digester (AAD) receiving continuous manure and antibiotic input. Manure samples were collected throughout the AAD system to evaluate baseline antibiotic and ARG input (raw manure), the effect of hygenization (post-pasteurized manure) and anaerobic digestion (post-digestion manure) on antibiotic and ARG levels. Antibiotics were analyzed by liquid chromatography-tandem mass spectrometry (LC-MS/MS), and the ARGs tet(O), tet(W), sul1 and sul2 were analyzed by quantitative polymerase chain reaction (Q-PCR). Significant reductions in the concentrations of chlortetracycline, oxytetracycline, tetracycline and their degradation products were observed in manure liquids following treatment (p < 0.001), concomitant to significant increases in manure solids (p < 0.001). These results suggest sorption is the major removal route for tetracyclines during AAD. Significant decreases in the epimer-to-total residue ratios for chlortetracycline and tetracycline in manure solids further indicate degradation is desorption-limited. Moreover, sul1 and sul2 copies decreased significantly (p < 0.001) following AAD in the absence of sulfonamide antibiotics, while tetracyclines-resistant genes remained unchanged. A cross-sectional study of dairy farms utilizing natural aeration and liquid solid separation treatments was additionally performed to compare levels of antibiotics and ARGs found in AAD with the levels in common manure management systems. The concentration of antibiotics in raw manure varied greatly between farms while minimal differences in ARGs were observed. However, significant (p < 0.01) differences in the levels of antibiotics and ARGs (except tet(W)) were observed in the effluents from the three different manure management systems. PMID- 29455090 TI - Characterization of p-Coumaric acid-induced soluble and cell wall-bound phenolic metabolites in relation to disease resistance to Xanthomonas campestris pv. campestris in Chinese cabbage. AB - To characterize the p-coumaric acid (pCA)-induced phenolic metabolites in relation to the disease resistance against Xanthomonas campestris pv. campestris (Xcc.), the responses of soluble- and cell wall-bound flavonoid and hydroxycinnamic acids compounds to the pretreatment of pCA or the inhibitor of the 4-coumarate-CoA ligase, 3,4-(methylenedioxy) cinnamic acid (MDCA), following Xcc inoculation were assessed, and the resulting data were interpreted with regard to susceptibility to Xcc in Chinese cabbage (Brassica rapa var. pekinensis). At 12 days post-inoculation (DPI) with Xcc, disease symptom development could be distinguished by necrotic lesions, and characterized by an enhanced lipid peroxidation. Overall, pCA acts as a positive stimulus for an accumulation of hydroxycinnamic acids and flavonoids, while MDCA acts as a negative regulator. Pretreatment with pCA resulted in an accumulation of specific hydroxycinnamic acids, pCA, ferulic acid (FA), and sinapic acid (SiA) in both soluble and cell wall-bound forms in Xcc-inoculated leaves, while MDCA pretreatment decreased accumulation in a dose-dependent manner. Two flavonoid compounds, epigallocatechin (EGC) and epigallocatechin gallate (EGCG), showed a similar response to pCA and MDCA pretreatments. These results indicate that a lower disease symptom development in pCA-pretreated leaves was associated with a higher accumulation of hydroxycinnamic acids and flavonoids, and vice-versa in MDCA- and non-pretreated (control) leaves. PMID- 29455091 TI - An UPLC-MS/MS method to determine CT-707 and its two metabolites in plasma of ALK positive advanced non-small cell lung cancer patients. AB - CT-707, a mutant-selective inhibitor of an important cancer target, anaplastic lymphoma kinase (ALK), is designed to be a targeted therapeutic agent for non small cell lung cancer (NSCLC) patients harboring ALK active and crizotinib resistant mutations. A rapid and sensitive ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method was developed and validated for the determination of CT-707 and its two metabolites (M1 and M2) in human plasma. The samples were purified by solid phase extraction (SPE) and separated on a BEH C18 column (2.1 * 50 mm, 1.7 MUm). Electrospray ionization (ESI) in positive ion mode and multiple reactions monitoring (MRM) were used to monitor the ion transitions at m/z 636.4+ -> 413.3+, 594.4+ -> 494.4+, 622.5+ -> 536.4+, respectively. The results indicated that the method had excellent sensitivity and selectivity. The linear range covered from 2 to 500 ng/mL for CT 707and from 1 to 100 ng/mL for M1 and M2. Intra-run and inter-run precisions (in terms of %RSD) were all <15% and the accuracies (in terms of %RE) were within the range of +/-15%. The lower limit of quantification (LLOQ), matrix effect, extraction recovery, stability, dilution test and carryover test were also validated and satisfied with the criteria of validation. Finally, the method was successfully applied to a phase I clinical study of ALK-positive advanced NSCLC patients after an oral administration of CT-707. PMID- 29455092 TI - Internet pseudoscience: Testing opioid containing formulations with tampering potential. AB - Drug tampering practices, with the aim to increase availability of drug delivery and/or enhance drug effects, are accessible on Internet and are practiced by some portion of recreational drug users. Not rarely, recreational misuse may result in toxic and even fatal results. The aim of the present study was to assess the tampering risk of medicaments containing different formulations of an opioid in combination with paracetamol or dexketoprofen, following the procedures reported in dedicated forums on the web. Tablets and suppositories containing codeine, tramadol and oxycodone were extracted following the reported "Cold water extraction"; dextromethorphan was extracted from cough syrup following the procedure reported as "Acid/base extraction" and fentanyl was extracted from transdermal patches according the procedure reported in Internet. The tampered products and opportunely prepared calibrators in water were analysed by liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). The separation of the analytes was carried on Agilent ZORBAX Eclipse Plus C18 (RRHT 2.1 mm * 50 mm, 1.8 MUm) by the gradient elution of 0.01% formic acid in water and 0.01% formic acid in methanol. Acquisition was by MRM mode considering at least two transitions for compound. Declared recoveries for these home-made extractions claimed to exceed 99% for the opioid and to complete remove paracetamol, often associated to liver toxicity and thus to obtain a "safer" preparation. In this study, the authors demonstrated that rarely the recoveries for the opioid reached 90% and that up to 60% of the paracetamol amount remained in solution. Thus, high risks for health remained both for the potential lethality of the opioid content, but also for the sub-lethal chronic use of these mixtures, which contained still uncontrolled, ignored, but often important amounts of paracetamol. PMID- 29455093 TI - Quantitative determination of a potent geranylgeranyl diphosphate synthase inhibitor using LC-MS/MS: Derivatization and application. AB - An isomeric mixture of homogeranyl/homoneryl triazole bisphosphonates (VSW1198) has previously been shown to be a potent inhibitor of geranylgeranyl diphosphate (GGDP) synthase (GGDPS) and of therapeutic interest for the treatment of multiple myeloma. We have developed and validated a selective and sensitive liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) method for the simultaneous quantitation of both the E- and Z- isomers of VSW1198 in cell culture media, mouse plasma and tissues. VSW1198 and internal standard are extracted from the bio-matrices by solid-phase extraction, followed by derivatization using trimethylsilyldiazomethane. The chromatographic separation of analytes was achieved on a Phenomenex Gemini NX column (150 mm * 2.0 mm, 5 MU) with gradient elution using 0.1% acetic acid and methanol/acetonitrile (1:1) as the mobile phase at a flow rate of 0.2 mL/min. Derivatized analytes were ionized with an electrospray ionization source in positive multiple reaction monitoring (MRM) mode and quantitated using MS/MS. The MS/MS response was linear over the concentration range from 0.38-1500 and 0.13-500 ng/mL for the E- and Z-isomers, respectively. The within- and between-day precision (relative standard deviation, % RSD) and accuracy were within the acceptable limits per FDA guidelines. The validated method was used for quantitative determination of the compounds in preclinical studies focused on the development of VSW1198 as a novel anti-cancer agent. PMID- 29455094 TI - Emodin attenuates titanium particle-induced osteolysis and RANKL-mediated osteoclastogenesis through the suppression of IKK phosphorylation. AB - Aseptic loosening due to wear particles is a serious challenge for orthopedic surgeons, sabotaging the long-term success of total joint arthroplasty. The existing treatments for aseptic loosening are still far from satisfactory, necessitating more aggressive drug exploration. Here, we examined the effect of emodin on titanium particle-induced osteolysis and further investigated its underlying mechanism in vivo and in vitro. Thirty-two C57BL/6 mice were randomly assigned into four groups: the Sham group (sham operation with vehicle injection), Vehicle group (titanium particle treatment with vehicle injections), Low group (titanium particle treatment with injections of 10 mg/kg/day emodin) and High group (titanium particle treatment with injections of 50 mg/kg/day emodin). Micro-CT scanning and histological analysis revealed that after emodin injections, the inflammatory response and bone destruction were markedly ameliorated. TRAP staining showed that osteoclast numbers were also dramatically reduced. Throughout the in vitro culture period, emodin significantly decreased the bone resorption area, number of osteoclasts and formation of F-actin rings. Mechanistic studies suggested that reduced NF-kappaB signaling might be mediating the inhibitory effects of emodin. Collectively, our findings suggest that emodin, a natural product extracted from Rheum palmatum, may be developed as a promising candidate for the treatment of wear particle-induced osteolysis and subsequent aseptic loosening. PMID- 29455095 TI - Establishment of pancreatic microenvironment model of ER stress: Quercetin attenuates beta-cell apoptosis by invoking nitric oxide-cGMP signaling in endothelial cells. AB - The involvement of endoplasmic reticulum (ER) stress in endothelial dysfunction and diabetes-associated complications has been well documented. Inhibition of ER stress represents a promising therapeutic strategy to attenuate endothelial dysfunction in diabetes. Recent attention has focused on the development of small molecule inhibitors of ER stress to maintain endothelial homeostasis in diabetes. Here we have developed a reliable, robust co-culture system that allows a study on the endothelial cells and pancreatic beta-cells crosstalk under ER stress and validated using a known ER stress modulator, quercetin. Furthermore, sensitizing of endothelial cells by quercetin (25 MUM) confers protection of pancreatic beta cells against ER stress through nitric oxide (NO?) signaling. In addition, increased intracellular insulin and NO?-mediated cyclic 3',5'-guanosine monophosphate (cGMP) levels in pancreatic beta-cells further confirmed the mechanism of protection under co-culture system. In addition, the potential protein targets of quercetin against ER stress in the endothelial cells were investigated through proteomic profiling and its phosphoprotein targets through Bioplex analysis. On the whole, the developed in vitro co-culture set up can serve as a platform to study the signaling network between the endothelial and pancreatic beta-cells as well as provides a mechanistic insight for the validation of novel ER stress modulators. PMID- 29455096 TI - Total inorganic nitrogen removal during the partial/complete nitrification for treating domestic wastewater: Removal pathways and main influencing factors. AB - Achieving nitrite accumulation was considered as the prerequisite of ANAMMOX, which hindered the application of ANAMMOX. In this study, total inorganic nitrogen (TIN) removal during the partial/complete nitrification was studied in a lab-scale sequencing batch reactor (SBR) for treating domestic wastewater. The results showed TIN was removed by denitrification, ANAMMOX and N2O emission during the partial/complete nitrification. AOB, AOA, Nitrobacter (NB), Nitrospira (NS), AnAOB and DNB were coexisted in the partial/complete nitrification. The microbial competition among these functional communities determined the type of nitrification, TIN removal and pathways. Since low DO concentrations benefits Nitrospira growth, the partial nitrification was damaged. After long-term operation, AOB gradually accommodated the low DO concentration. When Vmax,AOB (the maximum specific reaction rate of AOB) higher than Vmax,NOB (the maximum specific reaction rate of NOB), a part of nitrite was reduced by DNB and AnAOB. Therefore, TIN was removed during the complete nitrification. PMID- 29455097 TI - Development and application of a continuous fast microwave pyrolysis system for sewage sludge utilization. AB - A continuous fast microwave-assisted pyrolysis system was designed, fabricated, and tested with sewage sludge. The system is equipped with continuous biomass feeding, mixing of biomass and microwave absorbent, and separated catalyst upgrading. The effect of the sludge pyrolysis temperature (450, 500, 550, and 600 degrees C) on the products yield, distribution and potentially energy recovery were investigated. The physical, chemical, and energetic properties of the raw sewage sludge and bio-oil, char and gas products obtained were analyzed using elemental analyzer, GC-MS, Micro-GC, SEM and ICP-OES. While the maximum bio-oil yield of 41.39 wt% was obtained at pyrolysis temperature of 550 degrees C, the optimal pyrolysis temperature for maximum overall energy recovery was 500 degrees C. The absence of carrier gas in the process may be responsible for the high HHV of gas products. This work could provide technical support for microwave assisted system scale-up and sewage sludge utilization. PMID- 29455098 TI - Investigations in sonication-induced intensification of crude glycerol fermentation to dihydroxyacetone by free and immobilized Gluconobacter oxydans. AB - This study reports crude glycerol fermentation by G. oxydans for dihydroxyacetone (DHA) production, and intensification of fermentation with sonication. Fermentation was carried out using both free and immobilized cells (on polyurethane foam support) for initial glycerol concentrations of 20, 30 and 50 g/L. Sonication at 20% duty cycle enhanced glycerol consumption by 60-84% with no significant change in cell morphology. Lesser DHA yield in crude glycerol fermentation was attributed to possible formation of inhibitory products. Slight reduction in DHA yield for initial glycerol concentration of 50 g/L was attributed to substrate inhibition. Higher DHA productivity was obtained for immobilized cells. Circular dichroism analysis of intracellular proteins obtained from ultrasound-treated G. oxydans revealed significant reduction in alpha-helix and beta-sheet content. These conformational changes in protein structure could augment activity of intracellular glycerol dehydrogenase, which is manifested in terms of enhanced metabolism of glycerol by G. oxydans. PMID- 29455099 TI - Largely enhanced bioethanol production through the combined use of lignin modified sugarcane and xylose fermenting yeast strain. AB - The recalcitrant structure of lignocellulosic biomass is a major barrier in efficient biomass-to-ethanol bioconversion processes. The combination of feedstock engineering via modification in the lignin synthesis pathway of sugarcane and co-fermentation of xylose and glucose with a recombinant xylose utilizing yeast strain produced 148% more ethanol compared to that of the wild type biomass and control strain. The lignin reduced biomass led to a substantially increased release of fermentable sugars (glucose and xylose). The engineered yeast strain efficiently co-utilized glucose and xylose for fermentation, elevating ethanol yields. In this study, it was experimentally demonstrated that the combined efforts of engineering both feedstock and microorganisms largely enhances the bioconversion of lignocellulosic feedstock to bioethanol. This strategy will significantly improve the economic feasibility of lignocellulosic biofuels production. PMID- 29455100 TI - Hypofunction of left dorsolateral prefrontal cortex in depression during verbal fluency task: A multi-channel near-infrared spectroscopy study. AB - BACKGROUND: Previous functional neuroimaging studies of depression have demonstrated frontotemporal dysfunction, including the dorsolateral prefrontal cortex, while patients perform working memory and language comprehension tasks. Recent near-infrared spectroscopy (NIRS) studies have shown frontotemporal hypofunction in depression by verbal fluency task, but the regions of impairment affecting respective depressive symptoms still remain unclear. We investigated frontotemporal function during word production task in depression with multi channel NIRS. Further, we aimed to clarify whether any depressive symptoms affect frontotemporal dysfunction. METHODS: One hundred seventy-seven major depressive patients and 50 healthy control volunteers participated in this study. Their cerebral activations were compared during verbal fluency task. RESULTS: Although performance was not significantly different, hypoactivation in the bilateral frontotemporal regions was significantly observed in depressed patients, compared with controls. Left lateral frontotemporal activation was significantly reduced in the group with mandatory symptom, which is depressed mood, or loss of interest or pleasure, compared with the group that still has residual depressive symptoms in spite MDD having been remitted. LIMITATION: the MDD group had significantly higher age and education level than the controls. Conclusions Our findings indicate hypofunction of the bilateral frontotemporal regions in depression during verbal fluency task. Further, hypofunction of these regions in the left hemisphere by this task could reflect whether the subjects recovered from depressed mood, or loss of interest or pleasure. PMID- 29455101 TI - Does pedicle screw fixation of the subaxial cervical spine provide adequate stabilization in a multilevel vertebral body fracture model? An in vitro biomechanical study. AB - BACKGROUND: Cervical vertebral body fractures generally are treated through an anterior-posterior approach. Cervical pedicle screws offer an alternative to circumferential fixation. This biomechanical study quantifies whether cervical pedicle screws alone can restore the stability of a three-column vertebral body fracture, making standard 360 degrees reconstruction unnecessary. METHODS: Range of motion (2.0 Nm) in flexion-extension, lateral bending, and axial rotation was tested on 10 cadaveric specimens (five/group) at C2-T1 with a spine kinematics simulator. Specimens were tested for flexibility of intact when a fatigue protocol with instrumentation was used to evaluate construct longevity. For a C4 6 fracture, spines were instrumented with 360 degrees reconstruction (corpectomy spacer + plate + lateral mass screws) (Group 1) or cervical pedicle screw reconstruction (C3 and C7 only) (Group 2). FINDINGS: Results are expressed as percentage of intact (100%). In Group 1, 360 degrees reconstruction resulted in decreased motion during flexion-extension, lateral bending, and axial rotation, to 21.5%, 14.1%, and 48.6%, respectively, following 18,000 cycles of flexion extension testing. In Group 2, cervical pedicle screw reconstruction led to reduced motion after cyclic flexion-extension testing, to 38.4%, 12.3%, and 51.1% during flexion-extension, lateral bending, and axial rotation, respectively. INTERPRETATION: The 360 degrees stabilization procedure provided the greatest initial stability. Cervical pedicle screw reconstruction resulted in less change in motion following cyclic loading with less variation from specimen to specimen, possibly caused by loosening of the shorter lateral mass screws.

AB - NiS/g-C3N4/SrTiO3 (NS/CN/STO) composites were prepared using a facile hydrothermal method. The synergistic effect of g-C3N4/SrTiO3 (CN/STO) heterojunction and NiS cocatalyst enhanced the photocatalytic hydrogen evolution activity of NS/CN/STO. A hydrogen production rate of 1722.7 MUmol h-1 g-1 was obtained when the 2%NiS/20%g-C3N4/SrTiO3 (2NS/20CN/STO) was used for the photocatalytic hydrogen evolution in the presence of methanol used as a sacrificial agent under UV-vis light irradiation; the photocatalytic hydrogen production rate of 2NS/20CN/STO is 32.8, 8.9 and 4.2 times the value of that obtained with pure g-C3N4, SrTiO3 and 20%g-C3N4/SrTiO3 (20CN/STO), respectively. Moreover, in photoelectrochemical investigations when compared with 20CN/STO, SrTiO3 and g-C3N4, 2NS/20CN/STO exhibited significant photocurrent enhancement. The heterojunction and cocatalyst in NS/CN/STO improved the charge separation efficiency and the lifetime of the charge carriers, leading to the enhanced generation of electrons for photocatalytic hydrogen production.

AB - In order to apply the photocatalytic processes on a real scale for the treatment of industrial wastewaters, the use of slurry reactors employing suspended photocatalysts is not suitable due to the need for an uncomfortable and expensive separation phase of photocatalyst. To overcome this disadvantage, the photocatalyst particles must be immobilized on a transparent support: our work proposes, for this reason, a simple and cost effective method for the deposition of ZnO photocatalyst on glass spheres in order to formulate a structured photocatalyst effective in the treatment of aqueous solutions containing various organic dyes, commonly used in the tannery industries and in the treatment of a real wastewater at high COD content (11 g/L) coming from the refining unit of the tanning process. In particular, ZnO was immobilized on glass spheres (ZnO/GS) with a simple dip coating method, starting from zinc acetate aqueous solution, without using complexing agent and strong basic compounds. The optimization of ZnO amount on glass spheres was evaluated employing Acid Blue 7 dye, as model pollutant. In particular, it was found that best performances in terms of discoloration and mineralization of the target dye were obtained using the photocatalyst with a ZnO loading equal to 0.19 wt% (ZnO_ac1), prepared through only one dip-coating step. Moreover, the ZnO_ac1 photocatalyst can be easily separated from the reaction mixture, maintaining excellent photocatalytic activity and durability even after several reuse cycles. Finally, ZnO_ac1 showed a high photocatalytic activity in the treatment of the real wastewater, obtaining a COD removal equal to 70% after 180 min of UV light irradiation. PMID- 29455104 TI - SiO2@LaOF:Eu3+ core-shell functional nanomaterials for sensitive visualization of latent fingerprints and WLED applications. AB - For the first time, intense red color composite of SiO2@LaOF:Eu3+ core-shell nanostructures (NS) were fabricated via facile solvothermal method followed by thermal treatment. The obtained core-shell particles display better spherical shape and non-agglomeration with a narrow size distribution. Photoluminescence (PL) emission spectra exhibits intense peaks at ~593 nm, 611 nm, 650 nm corresponds to 5D0 -> 7FJ (J = 0, 1 and 2) Eu3+ transitions respectively. The spectral intensity parameters and Eu-O ligand behaviors are estimated by means of Judd-Ofelt (J-O) theory. CIE co-ordinates are found to be (x = 0.63, y = 0.36) which is very close to standard NTSC values (x = 0.67, y = 0.33). CCT value is ~3475 K which is less than 5000 K, as a result this phosphor is suitable for warm light emitting diodes. The optimized core-shell SiO2 (coat III)@LaOF:Eu3+ (5 mol%) was used as a fluorescent labeling marker for the visualization of latent fingerprints on both porous and non-porous surfaces. Obtained fingerprints are highly sensitive and selective also no background hindrance which enables level-I to level-III fingerprint ridge characteristics. Observed results indicate that the significant improvement in luminescence of coreshell NS can be explored as a sensitive functional nanopowder for advanced forensic and solid state lightning applications. PMID- 29455105 TI - Shedding light on metabotropic glutamate receptors using optogenetics and photopharmacology. AB - Metabotropic glutamate receptors (mGluRs) are a family of G protein-coupled receptors activated by glutamate, the main excitatory neurotransmitter of the mammalian central nervous system. These receptors are considered as potential therapeutic targets in many neurological diseases but a better understanding of their complex molecular dynamics and of their role in the normal and pathological functioning of the brain is still required. Manipulating mGluRs with high spatial and temporal precision holds great promise for deciphering their physiological and pathological functions. This article reviews several recently developed optogenetic and photopharmacological solutions for the optical control of mGluRs and their applications, from the study of the molecular dynamics of receptor activation to the study of their roles in vivo. PMID- 29455108 TI - Ureaplasma isolates differentially modulate growth factors and cell adhesion molecules in human neonatal and adult monocytes. AB - Generally regarded as commensal bacteria, the pathogenicity of Ureaplasma has often been considered low. Controversy remains concerning the clinical relevance of Ureaplasma infection in the pathogenesis of inflammation-related morbidities. Recently, we demonstrated Ureaplasma-driven pro-inflammatory cytokine responses in human monocytes in vitro. We hypothesized that Ureaplasma may induce further inflammatory mediators. Using qRT-PCR and multi-analyte immunoassay, we assessed the expression of granulocyte-colony stimulating factor (G-CSF), vascular endothelial growth factor (VEGF), intercellular adhesion molecule 1 (ICAM-1) and vascular cell adhesion molecule 1 (VCAM-1) in term neonatal and adult monocytes exposed to Ureaplasma urealyticum serovar 8 (Uu8) and U. parvum serovar 3 (Up3). Ureaplasma significantly induced VEGF mRNA in neonatal (Up3: p < 0.05, versus broth control) and adult monocytes (Uu8: p < 0.05) as well as ICAM-1 mRNA in neonatal cells (p < 0.05 each). As far as protein expression was concerned, Up3 stimulated VEGF release in both monocyte subsets (p < 0.01) and enhanced secretion of ICAM-1 protein in neonatal monocytes (p < 0.05). In adult cells, ICAM-1 protein release was increased upon exposure to both isolates (Uu8: p < 0.05, Up3: p < 0.01). Ureaplasma-induced responses did not significantly differ from corresponding levels mediated by E. coli lipopolysaccharide (LPS). The stimulatory effects were dose-dependent. Ureaplasma infection, on the contrary, did not affect G-CSF and VCAM-1 expression. Of note, co-infection of LPS-primed neonatal monocytes with Ureaplasma enhanced LPS-induced ICAM-1 release (Uu8: p < 0.05). Our results confirm Ureaplasma-driven pro-inflammatory activation of human monocytes in vitro, demonstrating a differential modulation of growth factors and cell adhesion molecules, that might promote unbalanced monocyte responses and adverse immunomodulation. PMID- 29455107 TI - Helios expression in regulatory T cells promotes immunosuppression, angiogenesis and the growth of leukemia cells in pediatric acute lymphoblastic leukemia. AB - Regulatory T cells (Tregs) characterized by the transcription factor forkhead box P3 (FoxP3) are crucial for maintaining immune tolerance and preventing autoimmunity. However, FoxP3 does not function alone and Helios is considered a potential candidate for defining Treg subsets. In this study, we investigated the expression and function of Helios for identifying Tregs in childhood precursor B cell acute lymphoblastic leukemia (pre-B ALL). Our results demonstrated that patients with pre-B ALL had a higher percentage of Helios+ FoxP3+ CD4+ Tregs. And there was a positive correlation between the expression of Helios and the suppressive function of Tregs, the risk gradation of ALL. Helios in combination with CD4 and FoxP3 may be an effective way to detect functional Tregs in pre-B ALL by promoting the secretion of transforming growth factor (TGF)-beta1. Furthermore, Helios+ Tregs could regulate angiogenesis in the BM niche of pre-B ALL via the VEGFA/VEGFR2 pathway. We also found Helios+ Tregs decreased apoptosis rate of nalm-6 cells by up-regulating the expression of anti-apoptosis protein Bcl-2. In summary, these data strongly imply the physiological importance of Helios expression in Tregs, and suggest that the manipulation of Helios may serve as a novel strategy for cancer immunotherapy.

AB - Microbes synthesize small, iron-chelating molecules known as siderophores to acquire iron from the environment. One way siderophores are generated is by nonribosomal peptide synthetases (NRPSs). The bioactive peptides generated by NRPS enzymes have unique chemical features, which are incorporated by accessory and tailoring domains or proteins. The first part of this review summarizes recent progress in NRPS structural biology. The second part uses the biosynthesis of pyochelin, a siderophore from Pseudomonas aeruginosa, as a case study to examine enzymatic methods for generating the observed diversity in NRPS-derived natural products. PMID- 29455109 TI - Dysregulation of JAK/STAT genes by vasoactive intestinal peptide (VIP) in Salmonella-infected monocytes may inhibit its therapeutic potential in human sepsis. AB - Murine/LPS models of Gram negative sepsis indicate that vasoactive intestinal peptide (VIP) has therapeutic potential. We investigated the unknown effect of VIP on JAK/STAT proteins and genes in human monocytes infected with Salmonella Typhimurium 14028. S. Typhimurium 14028 increased expression of both IL-6 receptor (IL-6R) and interferon gamma receptor 1 (IFNgammaR1) on monocytes but co culture of infected monocytes with VIP (10-7 M) only decreased expression of IFNgammaR1 (P < 0.05). In contrast, S. Typhimurium 14028 infection or co-culture with VIP had no effect on IL-10 receptor expression on the monocyte surface. However, S. Typhimurium 14028 down regulated IFNGR1 gene expression and this was not altered by co-culture with VIP, suggesting that changes in IFNgammaR1 protein may be due to an effect on cytoplasmic transport. 15 JAK/STAT genes, out of 84 studied, were up-regulated by S. Typhimurium 14028 infection and five were down regulated. Co-culture with VIP significantly decreased expression of two genes (IFNG and IL-20) and increased expression of three genes (SOCS1, SOCS3 and STAT4) (P < 0.05). S. Typhimurium 14028 also increased expression of PTPN1, which dephosphorylates JAK2 and TYK2. This was unaltered by co-culture with VIP but S. Typhimurium 14028-induced expression of ISG15, associated with susceptibility to Gram negative infection, was further increased by VIP. We conclude that the effect of VIP on JAK/STAT genes may preclude its therapeutic use in human Gram negative sepsis. PMID- 29455111 TI - DeepMitosis: Mitosis detection via deep detection, verification and segmentation networks. AB - Mitotic count is a critical predictor of tumor aggressiveness in the breast cancer diagnosis. Nowadays mitosis counting is mainly performed by pathologists manually, which is extremely arduous and time-consuming. In this paper, we propose an accurate method for detecting the mitotic cells from histopathological slides using a novel multi-stage deep learning framework. Our method consists of a deep segmentation network for generating mitosis region when only a weak label is given (i.e., only the centroid pixel of mitosis is annotated), an elaborately designed deep detection network for localizing mitosis by using contextual region information, and a deep verification network for improving detection accuracy by removing false positives. We validate the proposed deep learning method on two widely used Mitosis Detection in Breast Cancer Histological Images (MITOSIS) datasets. Experimental results show that we can achieve the highest F-score on the MITOSIS dataset from ICPR 2012 grand challenge merely using the deep detection network. For the ICPR 2014 MITOSIS dataset that only provides the centroid location of mitosis, we employ the segmentation model to estimate the bounding box annotation for training the deep detection network. We also apply the verification model to eliminate some false positives produced from the detection model. By fusing scores of the detection and verification models, we achieve the state-of-the-art results. Moreover, our method is very fast with GPU computing, which makes it feasible for clinical practice. PMID- 29455110 TI - Nipple-sparing bilateral prophylactic mastectomy and immediate reconstruction with TiLoop(r) Bra mesh in BRCA1/2 mutation carriers: A prospective study of long term and patient reported outcomes using the BREAST-Q. AB - BACKGROUND: Although demand for prophylactic mastectomy is increasing over time among women at a high risk for breast cancer, there is a paucity of studies on long term patient-reported outcomes after this procedure. METHODS: Between January 2011 and January 2015, 46 patients documented BRCA1/2 mutation carriers, eligible for prophylactic nipple-sparing mastectomy (NSM) and immediate breast prosthetic reconstruction were registered at our Institution. Patients underwent NSM and subcutaneous reconstruction with implant covered by a titanium-coated polypropylene mesh (TiLoop(r)). The BREAST-Q questionnaire was given to patients prior to surgery and at 1 and 2 years follow-up points. Capsular contracture was evaluated by Baker scale. Surgical outcomes along with the changes in BREAST-Q score were analyzed over time. RESULTS: Complications were reported in only one case and after two years the capsular contracture rates were acceptable (grade I: 65,2%; grade II: 32,6%; grade III 2,2%). At one year and two year follow-ups patients reported high rates in the measures of overall satisfaction with breasts (72,5 and 73,7 respectively), psychosocial well-being (78,4 and 78,6), sexual well-being (58,8 and 59,4), physical well-being (77,6 and 80,6) and overall satisfaction with outcome (75,7 and 79,7). A statistically significant increase in all BREAST-domains from the preoperative to the postoperative period was reported at one and two years follow-ups (p < 0,05). CONCLUSION: Following bilateral prophylactic NSM and immediate subcutaneous reconstruction with TiLoop(r), patients demonstrated high levels of satisfaction and quality of life as measured by BREAST-Q. 2-years outcomes confirmed high patient comfort with increased scores from the preoperative baseline level. PMID- 29455112 TI - Shielding properties of the ordinary concrete loaded with micro- and nano particles against neutron and gamma radiations. AB - The shielding properties of ordinary concrete doped with some micro and nano scaled materials were studied in the current study. Narrow beam geometry was simulated using MCNPX Monte Carlo code and the mass attenuation coefficient of ordinary concrete doped with PbO2, Fe2O3, WO3 and H4B (Boronium) in both nano and micro scales was calculated for photon and neutron beams. Mono-energetic beams of neutrons (100-3000 keV) and photons (142-1250 keV) were used for calculations. The concrete doped with nano-sized particles showed higher neutron removal cross section (7%) and photon attenuation coefficient (8%) relative to micro-particles. Application of nano-sized material in the composition of new concretes for dual protection against neutrons and photons are recommended. For further studies, the calculation of attenuation coefficients of these nano-concretes against higher energies of neutrons and photons and different particles are suggested. PMID- 29455113 TI - Experimental study and simulation of 63Zn production via proton induce reaction. AB - The 63Zn was produced by16.8 MeV proton irradiation of natural copper. Thick target yield for 63Zn in the energy range of 16.8 ->12.2 MeV was 2.47 +/- 0.12 GBq/MUA.h. Reasonable agreement between achieved experimental data and theoretical value of thick target yield for 63Zn was observed. A simple separation procedure of 63Zn from copper target was developed using cation exchange chromatography. About 88 +/- 5% of the loaded activity was recovered. The performance of FLUKA to reproduce experimental data of thick target yield of 63Zn is validated. The achieved results from this code were compared with the corresponding experimental data. This comparison demonstrated that FLUKA provides a suitable tool for the simulation of radionuclide production using proton irradiation.

AB - In this study, we created composite faces using mothers' faces to examine holistic face processing in infants aged 5-8 months. The composite-face effect occurred only in infants aged 7-8 months, suggesting that infants older than 7 months are able to process familiar faces holistically. PMID- 29455115 TI - Therapeutic use of heparin and derivatives beyond anticoagulation in patients with bronchial asthma or COPD. AB - In this review, we identify potential targets for the therapeutic effects of heparin in asthma and chronic obstructive pulmonary disease (COPD), consider the safety and delivery modalities of this therapeutic approach. Specifically, we point to the anti-inflammatory, antioxidant and mucolytic effects of unfractionated heparin with potential to modify disease progression in COPD and asthma when administered via the inhaled route. Inhaled heparin may represent an effective add-on therapy in COPD and asthma patient groups, especially when taking into consideration the relative deficiency in endogenous heparin reported in asthma patients. PMID- 29455116 TI - Linking mode of action of the model respiratory and photosynthesis uncoupler 3,5 dichlorophenol to adverse outcomes in Lemna minor. AB - Standard chemical toxicity testing guidelines using aquatic plant Lemna minor have been developed by several international standardisation organisations. Although being highly useful for regulatory purposes by focusing on traditional adverse endpoints, these tests provide limited information about the toxic mechanisms and modes of action (MoA). The present study aimed to use selected functional assays in L. minor after exposure to 3,5-dichlorophenol (3,5-DCP) as a model to characterise the toxic mechanisms causing growth inhibition and lethality in primary producers. The results demonstrated that 3,5-DCP caused concentration-dependent effects in chloroplasts and mitochondria. Uncoupling of oxidative phosphorylation (OXPHOS), reduction in chlorophyll (Chlorophyll a and b) content, reproduction rate and frond size were the most sensitive endpoints, followed by formation of reactive oxygen species (ROS), lipid peroxidation (LPO), reduction of carotenoid content and impairment of photosynthesis efficiency. Suppression of photosystem II (PSII) efficiency, electron transport rate (ETR), chlorophyll (a and b) contents and oxidative phosphorylation (OXPHOS) were closely correlated while ROS production and LPO were negative correlated with ETR, carotenoid content and growth parameters. A network of conceptual Adverse Outcome Pathways (AOPs) was developed to decipher the causal relationships between molecular, cellular, and apical adverse effects occurring in L. minor to form a basis for future studies with similar compounds. PMID- 29455117 TI - Road traffic accidents in Scottish military veterans. AB - Road traffic accidents (RTA) are recognised to be an important cause of death and injury in serving military personnel but little is known about the risk in veterans. We used data from the Scottish Veterans Health Study to examine the risk of RTA in a large national cohort of veterans, in comparison with people who had never served. We conducted a retrospective cohort study of 57,000 veterans and 173,000 non-veterans, followed up for up to 30 years, using survival analysis to compare risk of RTA injury. Subgroup analysis was used to explore trends by birth cohort and length of service. Overall, veterans had a higher risk of RTA (Cox proportional hazard ratio (HR) 1.17, 95% confidence intervals (CI) 1.14 1.20). The risk was highest in the veterans with the shortest service (early service leavers), including those who did not complete initial military training (HR 1.31, 95% CI 1.23-1.40). The mean age at first RTA was 34 years, irrespective of age at leaving service, and the greatest increase in risk was in veterans born in the 1960s, but veterans born after 1970 showed no increase in risk. We have therefore demonstrated that the increased risk of RTA observed in serving military personnel persists in veterans through the fourth decade of life. The high risk in early service leavers is likely to be related to risk factors other than military service, including previous childhood adversity. Recent Ministry of Defence road safety programmes may now be reducing the long-term risk of RTA injury. PMID- 29455118 TI - Multivariate dynamic Tobit models with lagged observed dependent variables: An effectiveness analysis of highway safety laws. AB - Highway safety laws aim to influence driver behaviors so as to reduce the frequency and severity of crashes, and their outcomes. For one specific highway safety law, it would have different effects on the crashes across severities. Understanding such effects can help policy makers upgrade current laws and hence improve traffic safety. To investigate the effects of highway safety laws on crashes across severities, multivariate models are needed to account for the interdependency issues in crash counts across severities. Based on the characteristics of the dependent variables, multivariate dynamic Tobit (MVDT) models are proposed to analyze crash counts that are aggregated at the state level. Lagged observed dependent variables are incorporated into the MVDT models to account for potential temporal correlation issues in crash data. The state highway safety law related factors are used as the explanatory variables and socio-demographic and traffic factors are used as the control variables. Three models, a MVDT model with lagged observed dependent variables, a MVDT model with unobserved random variables, and a multivariate static Tobit (MVST) model are developed and compared. The results show that among the investigated models, the MVDT models with lagged observed dependent variables have the best goodness-of fit. The findings indicate that, compared to the MVST, the MVDT models have better explanatory power and prediction accuracy. The MVDT model with lagged observed variables can better handle the stochasticity and dependency in the temporal evolution of the crash counts and the estimated values from the model are closer to the observed values. The results show that more lives could be saved if law enforcement agencies can make a sustained effort to educate the public about the importance of motorcyclists wearing helmets. Motor vehicle crash related deaths, injuries, and property damages could be reduced if states enact laws for stricter text messaging rules, higher speeding fines, older licensing age, and stronger graduated licensing provisions. Injury and PDO crashes would be significantly reduced with stricter laws prohibiting the use of hand-held communication devices and higher fines for drunk driving. PMID- 29455119 TI - Developing a safety heatmap of uncontrolled intersections using both conflict probability and severity. AB - This paper presents a method to assess the safety of uncontrolled intersections considering two major properties of traffic conflicts-conflict probability and severity. This method assesses both the safety level of the entire intersection in addition to the distribution of safety within it. Intersections are modeled by a two-dimensional Cartesian coordinate system and the internal space of intersections is divided into cells. First, the vehicle movement characteristics of an uncontrolled intersection are modeled. Second, the conflict probability of each cell within the intersection is estimated considering the approaching probability and lateral migration probability of vehicles. The quantification of conflict severity is based on kinetic energy loss of potential crashes. Cluster analysis is used to combine conflict probability and severity to model the safety assessment of each cell. Third, the application of the method is discussed, and an overall safety index of intersections is proposed which considers weighted safety level and relative value of areas of different safety levels. Finally, a case study, which includes three different designs, is presented along with safety heatmaps to demonstrate the results. The results not only demonstrate the validity of the model, but also indicate that the proposed method can be applied to: i) safety evaluation of build-up intersections; ii) dangerous position management within an intersection; iii) safety assessment of designed intersections, and iv) safety level comparison among different intersections or various designs for a single intersection. Using this method, engineers and planners can better evaluate and improve the safety of existing or future uncontrolled intersections. PMID- 29455120 TI - Amyand's hernia with acute gangrenous appendicitis and cecal perforation: A case report and review of the literature. AB - INTRODUCTION: An Amyand's hernia is a heterogeneous clinical condition defined by the presence of the vermiform appendix within an inguinal hernia sac, which may or may not contain other abdominal contents or pathologic inflammatory changes. Herein we present an exceptionally rare case of an Amyand's hernia containing acute appendicitis and a perforated cecum. PRESENTATION OF CASE: A 46-year-old male with a right inguinal hernia of 2-3 year duration presented to our Emergency Department complaining of acute onset abdominal and groin pain. The patient was diagnosed with an incarcerated right inguinal hernia and underwent emergent surgical repair. Intraoperatively a reactive fluid was found within the hernia sac that prompted an exploratory laparotomy for suspected bowel perforation. The hernia was then found to contain an inflamed gangrenous appendix with an inflamed and perforated cecum. An ileocecectomy and enteroenterostomy was performed and the hernia defect was repaired without mesh. DISCUSSION: With an estimated incidence of only 1%, Amyand's hernias are rare and lack a clear evidence-based management scheme. Moreover, they can contain a diverse range of pathologic features and presentations that can complicate diagnosis and treatment. To avoid potential morbidity and mortality, the surgeon must consider an Amyand's hernia on his or her differential when operating on inguinal hernias and be aware of the associated presentations, complications, and management schemes. CONCLUSION: There is a paucity of reports describing simultaneous appendicitis and cecal perforation within an Amyand's hernia. In our case, ileocecectomy and Bassini hernia repair with close follow-up led to a favorable outcome. PMID- 29455121 TI - Ozone assisted oxidation of gaseous PCDD/Fs over CNTs-containing composite catalysts at low temperature. AB - Ozone assisted carbon nanotubes (CNTs) supported vanadium oxide/titanium dioxide (V/Ti-CNTs) or vanadium oxide-manganese oxide/titanium dioxide (V-Mn/Ti-CNTs) catalysts towards gaseous PCDD/Fs (polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans) catalytic oxidations at low temperature (150 degrees C) were investigated. The removal efficiency (RE) and decomposition efficiency (DE) of PCDD/Fs achieved with V-Mn/Ti-CNTs alone were 95% and 45% at 150 degrees C under a space velocity (SV) of 14000 h-1; yet, these values reached 99% and 91% when catalyst and low concentration (50 ppm) ozone were used in combined. The ozone promotion effect on catalytic activity was further enhanced with the addition of manganese oxide (MnOx) and CNTs. Adding MnOx and CNTs in V/Ti catalysts facilitated the ozone decomposition (creating more active species on catalyst surface), thus, improved ozone utilization (demanding relatively lower ozone addition concentration). On the other hand, this study threw light upon ozone promotion mechanism based on the comparison of catalyst properties (i.e. components, surface area, surface acidity, redox ability and oxidation state) before and after ozone treatment. The experimental results indicate that a synergistic effect exists between catalyst and ozone: ozone is captured and decomposed on catalyst surface; meanwhile, the catalyst properties are changed by ozone in return. Reactive oxygen species from ozone decomposition and the accompanied catalyst properties optimization are crucial reasons for catalyst activation at low temperature. PMID- 29455122 TI - Benzotriazoles and benzothiazoles in paired maternal urine and amniotic fluid samples from Tianjin, China. AB - Benzotriazoles (BTRs) and benzothiazoles (BTHs) are two groups of heterocyclic compounds that are widely detected in the environment. In this study, the levels of BTRs and BTHs in 79 paired maternal urine and amniotic fluid samples from Tianjin were investigated. BTRs were detected in most maternal urine samples, with a median concentration of ?BTRs of 0.88 ng/mL. BTH was detected in all maternal urine samples, with a median concentration of 1.35 ng/mL. Tolyltriazole (TTR, i.e., the sum of 4-methyl-1H-benzotriazole and 5-methyl-1H-benzotriazole) and BTH were detected in amniotic fluid with detection rates (DRs) > 50% and median concentrations of 0.026 and 0.61 ng/mL, respectively. The median concentrations of ?BTRs and ?BTHs (0.026 and 0.72 ng/mL) in amniotic fluid were lower than those in maternal urine. The median ratio of the ?BTRs concentrations in amniotic fluid to those in maternal urine was 0.030, with a range of 0.017 1.82, while the median value for TTR, BTH and 5-Cl-1H-BTR were 0.12, 0.46, and 1.43, respectively. This indicates greater distribution in fetal excretion to 5 Cl-1H-BTR than BTH and TTR. The concentrations of ?BTRs in maternal urine exhibited significant distribution differences (p < 0.05) with respect to some parameters, including maternal age, gestational week, gravidity, parity, and fetal weight. However, no significant correlations (p > 0.05) were observed in target compounds in amniotic fluid for the epidemiological factors assessed herein. The geometric means of the estimated daily intakes were 1.15 (0.052-7.66) MUg/day and 1.92 (0.027-6.64) MUg/day for ?BTRs and ?BTHs in present study, which are lower than those reported in previous study.

AB - In this work, pyrocatalytic effect is realized in hydrothermally-synthesized pyroelectric NaNbO3 shape-controllable nanoparticles via the product of pyroelectric effect and electrochemical redox. A pyro-catalysis is designed to decompose dye wastewater. Under the 23-50 degrees C heating-cooling cycle, the maximum pyrocatalytic decomposition ratio of NaNbO3 nanorods, nanosheets and nanocubes are 96%, 76% and 33%, respectively. The pyrocatalytic effect of NaNbO3 nanoparticles is potential in developing a environmentally-friendly technology for room-temperature pyrocatalysis through utilizing natural heat energy. PMID- 29455124 TI - Combination effects of airborne particulate matter exposure and high-fat diet on hepatic fibrosis through regulating the ROS-endoplasmic reticulum stress TGFbeta/SMADs axis in mice. AB - BACKGROUND: Hepatic fibrosis, characterized by an excessive accumulation of extracellular matrix, is associated with toxic substance exposure, chronic infections, mechanical injury, airborne fine particulate matter (PM2.5) exposure and metabolic disease. This study aimed to investigate the effect and mechanism of long-term, real-world airborne particulate matter (PM) exposure on hepatic fibrosis and further explored whether combination treatment of PM exposure and high-fat diet (HFD) aggravate the adverse effects in mice. METHODS AND RESULTS: Six-week-old male C57BL/6J mice fed with either a standard chow diet (STD) or an HFD were treated with either filtered air (FA) or PM for 18 weeks. Metabolic parameters, histological examination, gene expression analysis, and Western blot analysis were utilized to measure the effect and mechanism of PM exposure on hepatic fibrosis and to further analyze the synergistic effect of HFD. Subchronic airborne PM exposure induces hepatic fibrosis in mice, and combination treatment of PM exposure and HFD accelerate the adverse effect. Meanwhile, subchronic exposure to real-world PM increased the level of hepatic ROS, and the expression of endoplasmic reticulum (ER) stress markers (GRP78 and CHOP), p-SMAD2 and p SMAD3, as well as up-regulated TGFbeta and collagen 1 in liver tissues. Furthermore, PM exposure and HFD displayed the synergistic effects on these changes in liver. CONCLUSION: Our findings indicate that airborne PM exposure aggravates HFD -induced hepatic fibrosis. The ROS-ER stress-TGFbeta/SMADs regulatory axis mediates the effects of airborne PM exposure on accelerating hepatic fibrosis. PMID- 29455125 TI - Trends in analytical techniques applied to particulate matter characterization: A critical review of fundaments and applications. AB - Epidemiological studies have shown the association of airborne particulate matter (PM) size and chemical composition with health problems affecting the cardiorespiratory and central nervous systems. PM also act as cloud condensation nuclei (CNN) or ice nuclei (IN), taking part in the clouds formation process, and therefore can impact the climate. There are several works using different analytical techniques in PM chemical and physical characterization to supply information to source apportionment models that help environmental agencies to assess damages accountability. Despite the numerous analytical techniques described in the literature available for PM characterization, laboratories are normally limited to the in-house available techniques, which raises the question if a given technique is suitable for the purpose of a specific experimental work. The aim of this work consists of summarizing the main available technologies for PM characterization, serving as a guide for readers to find the most appropriate technique(s) for their investigation. Elemental analysis techniques like atomic spectrometry based and X-ray based techniques, organic and carbonaceous techniques and surface analysis techniques are discussed, illustrating their main features as well as their advantages and drawbacks. We also discuss the trends in analytical techniques used over the last two decades. The choice among all techniques is a function of a number of parameters such as: the relevant particles physical properties, sampling and measuring time, access to available facilities and the costs associated to equipment acquisition, among other considerations. An analytical guide map is presented as a guideline for choosing the most appropriated technique for a given analytical information required.

AB - This study investigated the occurrence, removal and influence of plant-operating conditions on removal mechanisms of 83 VOCs in different treatment units of a CETP in Mumbai, treating industrial waste on primary and secondary level. A mass balance approach was used to predict VOC removal by volatilization, stripping, weir drop, adsorption, and biodegradation. Results indicate that ~17% of VOCs were removed by stripping in equalization tank and ~8% were removed by weir drop in primary clari-flocculator respectively. Biodegradation was the dominant mechanism in aeration tank and was relatively poor for hydrophobic compounds which were more vulnerable to removal by stripping. Stripping rates could be reduced by increasing the active biomass concentration and using fine pore diffusers to reduce the air/effluent ratio. Decrease in Henry's constant and compound concentration can shift the main removal mechanism from stripping to biodegradation. Results also show considerable agreement between measured (71.2%) and predicted (67.1%) total removal, especially in aeration tanks. Equalization tanks (actual, 20.5%, predicted, 16.9%), primary clari-flocculator (actual, 14.2%, predicted, 7.7%), and secondary clarifier units (actual, 29.5%, predicted, 16.8%) showed fairly acceptable differences in measured and predicted removal. The effect of other mechanisms on VOC removal need to be further explored owing to their major contribution to VOC removal. This study is the first attempt in understanding the mechanisms behind the removal of VOCs in each treatment unit, especially equalization tanks and clarifier units, which have been severely underestimated till date.

AB - In this study, the positive matrix factorization (PMF) model was used for source apportionment of ambient PM2.5 in two locations in the central Tehran from May 2012 through June 2013. The average PM2.5 mass concentrations were 30.9 and 33.2MUg/m3 in Tohid retirement home and the school dormitory, respectively. Metals and trace elements, water-soluble ions, and PM2.5 mass concentrations were used as inputs to the model. Concentrations of elemental and organic carbon (EC and OC), and meteorological data were also used as auxiliary variables to help with the factor identification and interpretation. A 7-factor solution was identified as the best solution for both sites. The identified source factors included vehicular emissions, secondary aerosol, industrial emissions, biomass burning, soil, and road dust (including tire and brake wear particles) in both sampling sites. Results indicated that almost half of PM2.5 mass can be attributed to vehicular emissions at both sites. Secondary aerosol was the second major contributor to PM2.5 mass concentrations at both sites, with contributions of around 25% on average for both sites. In addition, while two industrial factors were identified in Tohid retirement home (with an overall contribution of 17%), only one industrial factor (with a minimal contribution of <2%) was identified at Tohid retirement home, probably due to the fact that the retirement home is impacted to a higher degree by industry-related activities. The other factors included biomass burning, road dust, and soil, with overall contributions of around 20% in both sites. Results of this study clearly indicate the major role of traffic-related emissions (both tailpipe and non-tailpipe) on ambient PM2.5 concentrations, and can be used as a beneficial tool for air quality policy makers to mitigate adverse health effects of exposure to PM2.5. PMID- 29455127 TI - Technical basis for using passive sampling as a biomimetic extraction procedure to assess bioavailability and predict toxicity of petroleum substances. AB - Solid-phase microextraction fibers coated with polydimethylsiloxane (PDMS) provide a convenient passive sampling format to characterize bioavailability of petroleum substances. Hydrocarbons absorb onto PDMS in proportion to both freely dissolved concentrations and partitioning properties of the individual constituents, which parallels the mechanistic basis used to predict aquatic toxicity in the PETROTOX model. When deployed in a non-depletive manner, combining SPME with thermal desorption and quantification using gas chromatography-flame ionization creates a biomimetic extraction (BE) procedure that has the potential to simplify aquatic hazard assessments of petroleum substances since the total moles of all hydrocarbons sorbed to the fiber can be related to toxic thresholds in target lipid of aquatic organisms. The objective of this work is to describe the technical basis for applying BE measurements to predict toxicity of petroleum substances. Critical BE-based PDMS concentrations corresponding to adverse effects were empirically derived from toxicity tests on different petroleum substances with multiple test species. The resulting species sensitivity distribution (SSD) of PDMS effect concentrations was then compared and found consistent with the previously reported target lipid-based SSD. Further, BE data collected on samples of aqueous media dosed with a wide range of petroleum substances were highly correlated to predicted toxic units derived using the PETROTOX model. These findings provide justification for applying BE in environmental hazard and risk evaluations of petroleum substances and related mixtures. PMID- 29455129 TI - Comparative study of volatile organic compounds in ambient air using observed mixing ratios and initial mixing ratios taking chemical loss into account - A case study in a typical urban area in Beijing. AB - Volatile organic compounds (VOCs) can react with atmospheric radicals while being transported after being emitted, resulting in substantial losses. Using only observed VOC mixing ratios to assess VOC pollution, is therefore problematic. The observed mixing ratios and initial mixing ratios taking chemical loss into consideration were performed using data for 90 VOCs in the atmosphere in a typical urban area in Beijing in winter 2013 to gain a more accurate view of VOC pollution. The VOC sources, ambient VOC mixing ratios and compositions, variability and influencing factors, contributions to near-ground-ozone and health risks posed were assessed. Source apportionment should be conducted using initial mixing ratios, but health risks should be assessed using observed mixing ratios. The daytime daily mean initial mixing ratio (72.62ppbv) was 7.72ppbv higher than the daytime daily mean observed mixing ratio (64.90ppbv). Alkenes contributed >70% of the consumed VOCs. The nighttime daily mean observed mixing ratio was 71.66ppbv, 6.76ppbv higher than the daytime mixing ratio. The observed mixing ratio for 66 VOCs was 40.31% higher in Beijing than New York. The OFPs of Ini-D (266.54ppbv) was underestimated 23.41% compared to the OFP of Obs-D (204.14ppbv), improving emission control of ethylene and propene would be an effective way of controlling O3. Health risk assessments performed for 28 hazardous VOCs show that benzene, chloroform, 1,2-dichloroethane, and acetaldehyde pose carcinogenic risk and acrolein poses non-carcinogenic risks. Source apportionment results indicated that vehicle exhausts, solvent usage and industrial processes were the main VOC source during the study. PMID- 29455130 TI - Structural and functional characteristics of buffer strip vegetation in an agricultural landscape - high potential for nutrient removal but low potential for plant biodiversity. AB - Vegetated buffer strips constitute a transition zone between terrestrial and aquatic ecosystems and provide several ecosystem services. Buffer strips are often applied as a mitigation measure against diffuse pollution in agricultural areas, primarily because they may retain nutrients and in this way help protect the aquatic environment. Additionally, they can improve biodiversity in an otherwise homogenous landscape and may therefore have a value in their own right. In the present study, we characterized the structural and functional features of the vegetation in Danish buffer strips using a nationwide dataset to explore: i) their floristic quality in terms of species diversity and conservation value and ii) based on their functional characteristics, their potential to retain nutrients. Moreover, we analyzed how the structural and functional characteristics varied along gradients in the environmental features of the catchment. We found that the floristic quality of the buffer vegetation was generally low, exhibiting an average of only 3.3% of the number of species of conservation interest. Instead, Danish buffer strips were dominated by widespread and productive species that are tolerant of anthropogenic impacts in the catchment. The abundance of highly productive plant species was positively related to high intensity land use, whereas the abundance of stress-tolerant plant species was positively related to low intensity land use. The high productivity of the buffer strips implies a large bio-storage potential, and these areas might therefore offer an opportunity to remove nutrients by harvesting the plant biomass. We discuss how Danish buffer strips could be exploited via appropriate management (e.g. harvesting) to maximize nutrient retention and at the same time improve floristic quality. PMID- 29455131 TI - Downscaling hydrodynamics features to depict causes of major productivity of Sicilian-Maltese area and implications for resource management. AB - Chlorophyll-a (CHL-a) and sea surface temperature (SST) are generally accepted as proxies for water quality. They can be easily retrieved in a quasi-near real time mode through satellite remote sensing and, as such, they provide an overview of the water quality on a synoptic scale in open waters. Their distributions evolve in space and time in response to local and remote forcing, such as winds and currents, which however have much finer temporal and spatial scales than those resolvable by satellites in spite of recent advances in satellite remote-sensing techniques. Satellite data are often characterized by a moderate temporal resolution to adequately catch the actual sub-grid physical processes. Conventional pointwise measurements can resolve high-frequency motions such as tides or high-frequency wind-driven currents, however they are inadequate to resolve their spatial variability over wide areas. We show in this paper that a combined use of near-surface currents, available through High-Frequency (HF) radars, and satellite data (e.g., TERRA and AQUA/MODIS), can properly resolve the main oceanographic features in both coastal and open-sea regions, particularly at the coastal boundaries where satellite imageries fail, and are complementary tools to interpret ocean productivity and resource management in the Sicily Channel. PMID- 29455132 TI - Rapid sewage pollution assessment by means of the coverage of epilithic taxa in a coastal area in the SW Atlantic. AB - The sewage pollution impact over coastal environment represents one of the main reasons explaining the deterioration of marine coastal ecosystems around the globe. This paper aims to detect promptly a putative sewage pollution impact in a Southwestern Atlantic coastal area of Argentina as well as to identify a straightforward way for monitoring, based on the relative abundance coverage of the intertidal epilithic taxa. Four sampling sites were distributed at increased distances from the sewage outfall where the cover of individual epilithic species was visually estimated. The surrounded outfall area (i.e. outfall site) resulted polluted with high percentages of organic matter in sediment and Enterococcus concentration in seawater. The structure of the community showed a remarkable difference between the polluted site (outfall site) and the unpolluted sites. The polychaete Boccardia proboscidea dominated the outfall site with variable abundances of the green algae Ulva sp. during the period of study, decreasing the diversity of the community, while the mussel Brachidontes rodriguezii and variable abundances of several algae species dominated the unpolluted sites. The monitoring of the benthic community represents an effective, non-destructive, relative inexpensive and rapid method to assess the health of the coastal environment in the study area. The large abundance of B. proboscidea along with the absence of B. rodriguezii individuals at <300m to the sewage outfall discharge allowed the success of this classical monitoring method in a temperate marine-coastal ecosystem with certain gradient of pollution. PMID- 29455133 TI - Viscous effects on the interaction of granular particles with floating oils in water. AB - Light hydrophobic liquids (LHLs) can be submerged in water with granular particles by forming particle encapsulated liquid sacks. Formation and submergence of granular encapsulated LHL sacks can be an effective method for capturing and controlling the fate of floating oils. However, formation characteristics of the LHL sacks and effect of LHL viscosity on their behavior are not well understood. In this study, we examined the encapsulation characteristics of LHL sacks depending on liquid viscosity. Silicone oils with viscosities ranging from 10cSt to 1000cSt were used as the LHLs. Sand with two different particle sizes (40-100mesh and 20-30mesh) were used as the granular particles. The submerged LHL sacks were stable and remained separate from each other without collapsing or aggregating over time. They could be moved in water by sliding while keeping their encapsulation. PMID- 29455134 TI - The increase of soil organic carbon as proposed by the "4/1000 initiative" is strongly limited by the status of soil development - A case study along a substrate age gradient in Central Europe. AB - During COP 21 in Paris 2015, several states and organizations agreed on the "4/1000" initiative for food security and climate. This initiative aims to increase world's soil organic carbon (SOC) stocks by 40/00 annually. The influence of soil development status on SOC dynamics is very important but usually not considered in studies. We analyse SOC accumulation under forest, grassland and cropping systems along a soil age gradient (10-17,000years) to show the influence of soil development status on SOC increase. SOC stocks (0-40cm) and accumulation rates along a chronosequence in alluvial soils of the Danube River in the Marchfeld (eastern Austria) were analysed. The analysed Fluvisols and Chernozems have been used as forest, grassland and cropland for decades or hundreds of years. The results showed that there is a fast build-up of OC stocks (0-40cm) in young soils with accumulation of ~1.3tha-1a-1 OC in the first 100years and ~0.5tha-1a-1 OC between 100 and 350years almost independent of land use. Chernozems with a sediment deposition age older than 5.000years have an accumulation rate<0.01tOCha-1a-1 (0-40cm). Radiocarbon dating showed that the topsoil (0-10cm) consists mainly of ">modern" and "modern" carbon indicating a fast carbon cycling. Carbon in subsoil is less exposed to decomposition and OC can be stored at long-time scales in the subsoil (14C age of 3670+/-35 BP). In view of the '4/1000' initiative, soils with constant carbon input (forest & grassland) fulfil the intended 40/00 growth rate of SOC stocks only in the first 60years of soil development. We proclaim that under the present climate in Central Europe, the increase of SOC stocks in soil is strongly affected by the state of soil development. PMID- 29455135 TI - Distinguishing two phenotypes of blooms using the normalised difference peak valley index (NDPI) and Cyano-Chlorophyta index (CCI). AB - Harmful algal blooms are now widely recognised as a severe threat to freshwater ecosystems, particularly in semi-fluvial environments created by river damming. Given the high spatial and temporal variability of cyanobacterial blooms, remote sensing is more suitable than conventional field surveys in monitoring blooms. However, the majority of existing algorithms cannot distinguish cyanobacterial blooms from eukaryotic algal blooms by extracting spectral features in the remote sensing reflectance (Rrs). In this study, in situ Rrs spectra of cyanobacterial and green algal blooms in Lakes Gaoyang, Hanfeng and Changshou of the Three Gorges Reservoir (TGR) in China were recorded. Characteristic spectral indices, namely, the normalised difference peak-valley index and Cyano-Chlorophyta index, were used to develop an algorithm that can effectively distinguish cyanobacterial and green algal blooms. The proposed algorithm was also used to investigate the spatio-temporal dynamics of the two phenotypes of blooms derived from Huan Jing 1 charge-coupled device images. The resulting accuracy of 93.5% demonstrated that remote sensing technology, in conjunction with field observation, could efficiently differentiate bloom-forming species and assess the water quality in the TGR. PMID- 29455136 TI - Acclimation process of cultivating Chlorella vulgaris in toxic excess sludge extract and its response mechanism. AB - Chlorella vulgaris was cultivated in the gradually increased proportion of toxic sludge extracts for acclimation, which was obtained from SBR treated synthetic wastewater containing mixed chlorophenols (2,4,6-trichlorophenol and 4 chlorophenol). The growth of C. vulgaris was obviously improved after acclimation with the cell number in the 100% sludge group was 22.75+/-0.85*106cellmL-1, which was relatively more than the BG11 control group's (20.80+/-0.35*106cellmL-1) and apparently over the 100% sludge group (10.78+/-0.45*106cellmL-1). Compared with the sludge control sludge group, C. vulgaris in the acclimation group gained 24.1% and 18.2% more relative removal rate about TOC and ecotoxicity, respectively. Proteomics analysis showed that protein spots were more clear and centralized and the clarifications of the different protein spots narrowed from 8 to 5 after acclimation. Proteins related to oxidoreducase activity and energy metabolism were over expressed and C. vulgaris could select the metabolic pathways, especially enhanced pyruvate fermentation, TCA cycle, and glycolysis after acclimation, by over accumulating the corresponding vital enzymes. Conclusively, acclimation was a good method to improve the removal ability and growth of C. vulgaris and algae could acclimatize itself to grow upon the toxic sludge extracts by metabolic selection. We suppose acclimation process was a potential method for algae wastewater treatment and algae cultivation without or reduce dilution. PMID- 29455137 TI - Can the watershed non-point phosphorus pollution be interpreted by critical soil properties? A new insight of different soil P states. AB - The physicochemical properties of surface soil play a key role in the fate of watershed non-point source pollution. Special emphasis is needed to identify soil properties that are sensitive to both particulate P (PP) pollution and dissolved P (DP) pollution, which is essential for watershed environmental management. The Chaohu Lake basin, a typical eutrophic lake in China, was selected as the study site. The spatial features of the Non-point Source (NPS) PP loads and DP loads were calculated simultaneously based on the integration of sediment delivery distributed model (SEDD) and pollution loads (PLOAD) model. Then several critical physicochemical soil properties, especially various soil P compositions, were innovatively introduced to determine the response of the critical soil properties to NPS P pollution. The findings can be summarized: i) the mean PP load value of the different sub-basins was 5.87 kg, and PP pollution is regarded to be the primary NPS P pollution state, while the DP loads increased rapidly under the rapid urbanization process. ii) iron-bound phosphorus (Fe-P) and aluminum-bound phosphorus (Al-P) are the main components of available P and showed the most sensitive responses to NPS PP pollution, and the correlation coefficients were approximately 0.9. Otherwise, the residual phosphorus (Res-P) was selected as a sensitive soil P state that was significantly negatively correlated with the DP loads. iii) The DP and PP concentrations were represented differently when they were correlated with various soil properties, and the clay proportion was strongly negatively related to the PP loads. Meanwhile, there is a non-linear relationship between the DP loads and the critical soil properties, such as Fe and Total Nitrogen (TN) concentrations. Specifically, a strong inhibitory effect of TN concentration on the DP load was apparent in the Nanfei river (NF) and Paihe (PH) river basins where the R2 reached 0.67, which contrasts with the relatively poor relationship within the other five basins. In addition, the degree of correlation between the Fe and DP loads severely degraded in the basins that were mostly covered by construction land or those that underwent a rapid urbanization process. The findings indicate that land use/cover change (LUCC), especially the distribution of agricultural land and construction land, as well as the soil background information (TN, Fe and Soil organic matters, etc.) can be considered as factors that influence NPS P pollution.

PMID- 29455139 TI - Implications of movement for species distribution models - Rethinking environmental data tools. AB - Movement is considered an essential process in shaping the distributions of species. Nevertheless, most species distribution models (SDMs) still focus solely on environment-species relationships to predict the occurrence of species. Furthermore, the currently used indirect estimates of movement allow to assess habitat accessibility, but do not provide an accurate description of movement. Better proxies of movement are needed to assess the dispersal potential of individual species and to gain a more practical insight in the interconnectivity of communities. Telemetry techniques are rapidly evolving and highly capable to provide explicit descriptions of movement, but their usefulness for SDMs will mainly depend on the ability of these models to deal with hitherto unconsidered ecological processes. More specifically, the integration of movement is likely to affect the environmental data requirements as the connection between environmental and biological data is crucial to provide reliable results. Mobility implies the occupancy of a continuum of space, hence an adequate representation of both geographical and environmental space is paramount to study mobile species distributions. In this context, environmental models, remote sensing techniques and animal-borne environmental sensors are discussed as potential techniques to obtain suitable environmental data. In order to provide an in-depth review of the aforementioned methods, we have chosen to use the modelling of fish distributions as a case study. The high mobility of fish and the often highly variable nature of the aquatic environment generally complicate model development, making it an adequate subject for research. Furthermore, insight into the distribution of fish is of great interest for fish stock assessments and water management worldwide, underlining its practical relevance. PMID- 29455140 TI - Comparison of soil organic carbon speciation using C NEXAFS and CPMAS 13C NMR spectroscopy. AB - We compared synchrotron-based C near-edge X-ray absorption fine structure (NEXAFS) and CPMAS 13C nuclear magnetic resonance (NMR) spectroscopy with respect to their precision and accuracy to quantify different organic carbon (OC) species in defined mixtures of soil organic matter source compounds. We also used both methods to quantify different OC species in organic surface horizons of a Histic Leptosol as well as in mineral topsoil and subsoil horizons of two soils with different parent material, stage of pedogenesis, and OC content (Cambisol: 15-30 OC mgg-1, Podzol: 0.9-7 OC mgg-1). CPMAS 13C NMR spectroscopy was more accurate and precise (mean recovery of different C functional groups 96-103%) than C NEXAFS spectroscopy (mean recovery 92-113%). For organic surface and topsoil samples, NMR spectroscopy consistently yielded larger O-alkyl C percentages and smaller alkyl C percentages than C NEXAFS spectroscopy. For the Cambisol subsoil samples both methods performed well and showed similar C speciation results. NEXAFS spectroscopy yielded excellent spectra with a high signal-to-noise ratio also for OC-poor Podzol subsoil samples, whereas this was not the case for CPMAS 13C NMR spectroscopy even after sample treatment with HF. Our results confirm the analytical power of CPMAS 13C NMR spectroscopy for a reliable quantitative OC speciation in soils with >10mgOCg-1. Moreover, they highlight the potential of synchrotron-based C NEXAFS spectroscopy as fast, non-invasive method to semi quantify different C functional groups in soils with low C content (0.9-10mgg-1). PMID- 29455141 TI - Comparison of scoring tools for the prediction of in-hospital mortality in status epilepticus. AB - PURPOSE: Several scoring tools have been developed for the prognostication of outcome after status epilepticus (SE). In this study, we compared the performances of STESS (Status Epilepticus Severity Score), mSTESS (modified STESS), EMSE-EAL (Epidemiology-based Mortality Score in Status Epilepticus- Etiology, Age, Level of Consciousness) and END-IT (Encephalitis-NCSE-Diazepam resistance-Image abnormalities-Tracheal intubation) in predicting in-hospital mortality after SE. METHOD: Data collected retrospectively from a cohort of 287 patients with SE were used to calculate STESS, mSTESS, EMSE-EAL, and END-IT scores. The differences between the scores' performances were determined by means of area under the ROC curve (AUC) comparisons and McNemar testing. RESULTS: The in-hospital mortality rate was 11.8%. The AUC of STESS (0.628; 95% confidence interval (CI), 0.529-0.727) was similar to that of mSTESS (0.620; 95% CI, 0.510 0.731), EMSE-EAL (0.556; 95% CI, 0.446-0.665), and END-IT (0.659; 95% CI, 0.550 0.768; p > .05 for each comparison) in predicting in-hospital mortality. STESS with a cutoff of 3 was found to have lowest specificity and number of correctly classified episodes. EMSE-EAL with a cutoff at 40 had highest specificity and showed a trend towards more correctly classified episodes while sensitivity tended to be low. END-IT with a cutoff of 3 had the most balanced sensitivity specificity ratio. CONCLUSIONS: EMSE-EAL is as easy to calculate as STESS and tended towards higher diagnostic accuracy. Adding information on premorbid functional status to STESS did not enhance outcome prediction. END-IT was not superior to other scores in prediction of in-hospital mortality despite including information of diagnostic work-up and response to initial treatment. PMID- 29455142 TI - Cereal powdery mildew effectors: a complex toolbox for an obligate pathogen. AB - Cereal powdery mildews are major pathogens of cultivated monocot crops, and all are obligate biotrophic fungi that can only grow and reproduce on living hosts. This lifestyle is combined with extreme host specialization where every mildew subspecies (referred to as forma specialis) can only infect one plant species. Recently there has been much progress in our understanding of the possible roles effectors play in this complex host-pathogen interaction. Here, we review current knowledge on the origin, evolution, and mode of action of cereal mildew effectors, with a particular focus on recent advances in the identification of bona fide effectors and avirulence effector proteins from wheat and barley powdery mildews. PMID- 29455143 TI - The birth and death of effectors in rapidly evolving filamentous pathogen genomes. AB - Plant pathogenic fungi and oomycetes are major risks to food security due to their evolutionary success in overcoming plant defences. Pathogens produce effectors to interfere with host defences and metabolism. These effectors are often encoded in rapidly evolving compartments of the genome. We review how effector genes emerged and were lost in pathogen genomes drawing on the links between effector evolution and chromosomal rearrangements. Some new effectors entered pathogen genomes via horizontal transfer or introgression. However, new effector functions also arose through gene duplication or from previously non coding sequences. The evolutionary success of an effector is tightly linked to its transcriptional regulation during host colonization. Some effectors converged on an epigenetic control of expression imposed by genomic defences against transposable elements. Transposable elements were also drivers of effector diversification and loss that led to mosaics in effector presence-absence variation. Such effector mosaics within species was the foundation for rapid pathogen adaptation. PMID- 29455144 TI - Evaluation of childhood trauma with respect to criminal behavior, dissociative experiences, adverse family experiences and psychiatric backgrounds among prison inmates. AB - OBJECTIVE: To evaluate childhood trauma in relation to criminal behavior, dissociative experiences, adverse family experiences during childhood and psychiatric backgrounds among prison inmates. METHODS: In total, 200 prison inmates were included in this questionnaire-based study. Data on demographic characteristics, adverse family experiences during childhood and psychiatric backgrounds were collected via face-to-face interviews, and a psychometric evaluation was conducted using the Childhood Trauma Questionnaire (CTQ-28) and Dissociative Experiences Scale (DES). RESULTS: Several historical items were more common in females than in males including family history of psychiatric disease (23.0% vs. 13.0%, p = 0.048), a personal history of psychiatric disease (51.0% vs. 29.0%, p < 0.001), and previous suicide attempts (49.0% vs. 25.0%, p < 0.001). In male inmates, in contrast, there were higher rates of substance abuse (48.0% vs. 29.0%, p < 0.001) and previous convictions (50.0% vs. 25.0%, p < 0.001). Males had a younger age at first crime (24.9 +/- 8.9 years vs. 30.3 +/- 9.2 years, p < 0.001), whereas females had higher rates of violent crimes (69.2% vs. 30.8% p < 0.001) and higher CTQ total scores (51.9 +/- 20.9 vs. 46.2 +/- 18.9, p = 0.04). A significant relationship of CTQ total score was noted with age at first offense (beta = 0.772, p < 0.001) but not with sentence length (beta = 0.075, p = 0.292). There were also possible mediating roles of psychiatric problems, adverse family experiences and DES in the relationship between CTQ and age at first offense. CONCLUSION: In conclusion, our findings revealed a high prevalence of and significant associations among childhood trauma, dissociative experiences, adverse family experiences and psychiatric problems in a cohort of incarcerated females and males. A psychiatric background, childhood trauma characterized by sexual abuse and violent crimes were found to be predominant in female prison inmates, whereas a criminal background with a younger age at first offense and frequent previous convictions, substance use and sexual crimes were more prevalent among male prison inmates. Our findings indicate a potential link between childhood traumatization and criminal behavior in terms of subsequent offending but not in terms of severity of the subsequent offense. PMID- 29455145 TI - Heavy metals dispersion during thermal treatment of plastic bags and its recovery. AB - One of the main worries for thermal treatment of plastic bag (PB) is the air pollution resulting from heavy metal (HM) evaporation and emission. The quest of the study was to investigate their fate during thermal treatment varying with temperature and atmosphere to explore the appropriate treatment technology. Four commonly consumed polymer bags such as PE, HDPE, LDPE and PVC were selected for the analysis. The elemental compositions, heating values and total metal contents of the samples were measured by an elemental analyzer, a sulphur/halogen analyzer, a bomb calorimeter and an ICP-OES, respectively. Thermal treatments of the samples were conducted in a tube furnace at 350, 550, 650, 750, and 850 degrees C with 1 L/min air or N2 gas flow, respectively. 5% HNO3/10% H2O2 solution was used for absorbing metals from gas phase, and then HM distributions both in flue gas and bottom ash were determined. Results revealed that the lower heating values of HDPE, LDPE, PVC and PE bags were 33.32, 34.28, 24.82 and 36.7 MJ/kg, respectively indicating energy recovery potential. Thermal treatment showed the maximum mass reduction (>90%) of PB at 850 degrees C. The higher percentage of metals was distributed in ash at initial temperature that promoted to gas with rise of temperature. The used absorption solution exhibited tremendous quantity of metals recovery. However, there was no significant difference between using air and N2 gas flow during treatment of PB. PMID- 29455146 TI - Global variations in pesticide regulations and health risk assessment of maximum concentration levels in drinking water. AB - Pesticides are used worldwide in agricultural, residential garden, and commercial applications. The control of pesticide exposure is a worldwide problem since pesticide can enter human body via ingestion, inhalation, and dermal contact. For drinking water, many regulatory jurisdictions respond by specifying the maximum concentration level (MCL) of a pesticide that may occur. At least 145 regulatory jurisdictions in 103 nations have specified at least 5474 pesticide MCLs in drinking water. Unfortunately, regulatory agencies often disagree on the magnitude of MCLs. For individual pesticides, MCLs often vary five, six, or even seven orders of magnitude. An analysis of the drinking water MCL distributions of the 25 most commonly regulated pesticides (N > 100 MCLs each) is presented in this study. Health risk uncertainty models are applied to compute uncertainty bounds around realistic MCL values for each pesticide and to help examine whether these MCLs can protect human health or not. Results indicated that at least 162 MCLs for 23 of the 25 pesticides considered were found to exceed upper human health risk uncertainty bounds indicating that these MCLs may not be adequate to protect human health. Also, health risk characterization factors were computed based on the estimation of maximum legal exposures to quantify human health damage caused by drinking water pesticide MCLs, and results indicated that some pesticide MCLs could cause over 19,000 Disability-Adjusted Life Years (DALYs) per million population. These MCLs distributions are highly influenced by several value clusters dominated by U.S., World Health Organization, and European Union (EU) indicating that consensus MCLs may be emerging for these most commonly regulated pesticides.

AB - A novel type of photocatalyst - hybrids of amino-grafted titania and reduced graphene oxide - was synthesized by a hydrothermal method. The hybrids were comprehensively analyzed, including determination of their morphology (TEM), porous structure parameters (low-temperature N2 sorption) and crystalline structure (XRD). Additionally, to confirm the effective bonding of the amino grafted titania and reduced graphene oxide, Raman and X-ray photoelectron spectroscopy (XPS) were used, in addition to elemental analysis. The key stage of the research was an evaluation of the photocatalytic activity of the synthesized hybrid photocatalysts with respect to the decomposition of C.I. Basic Blue 9 and C.I. Basic Red 1 dyes. It was found that the amino-grafted titania/reduced graphene oxide hybrids exhibited better photocatalytic activity in the degradation of C.I. Basic Blue 9 and C.I. Basic Red 1 than amino-grafted TiO2 alone.

AB - Micropollutants such as pharmaceutical active compounds, present at high concentration in hospital wastewater (HWW), pose both environmental and human health challenges. Fungal reactors can effectively remove such contaminants and produce non-toxic effluents, but their ability to operate for a long period of time is yet to be demonstrated in real hospital wastewater. Several process variables need to be studied beforehand. Here, variables: pellet size, aeration and carbon-to-nitrogen ratio are studied in continuous operations with real HWW. Moreover, a novel strategy for inoculum production that could reduce economical and operational costs is proposed and tested. Optimum pellet size was found to be 2 mm and an aeration of 0.8 L min-1 was needed to maintain fungal viability. The carbon-to-nitrogen ratio of 7.5 was selected and the pellet production time was reduced from 6 to 3 days. The novel low-cost inoculum preparation produced pellets with the same characteristics as the traditionally prepared ones.

AB - Fluoride has both detrimental and beneficial effects on living beings depending on the concentration and consumption periods. The study presented in this article investigated the feasibility of using neem oil phenolic resin treated lignocellulosic bio-sorbents for fluoride removal from water through fixed bed column study. Results indicated that treated bio-sorbents could remove fluoride both from synthetic and groundwater with variable bed depth, flow rate, fluoride concentration and column diameter. Data obtained from this study indicated that columns with the thickest bed, lowest flow rate, and fluoride concentration showed best column performance. Bio-sorbents used in this study are regenerable and reusable for more than five cycles. The initial materials cost needed to remove one gram of fluoride also found to be lower than the available alternatives. This makes the process more promising candidate to be used for fluoride removal. In addition, the process is also technically advantageous over the available alternatives. PMID- 29455151 TI - Nutrient management via struvite precipitation and recovery from various agroindustrial wastewaters: Process feasibility and struvite quality. AB - Improving environmental protection and finding sustainable and renewable resources of nutrients are core issues in circular bioeconomy. Thus, this study evaluated the efficiency of recovering struvite, MgNH4PO4.6H2O, from different agro-industrial wastewaters (four highly loaded reject waters of anaerobically co digested agro-industrial waste and a raw swine slurry) and assessed the quality of recovered struvite crystals and their reusability as fertilizer. The efficiency of crystallization (Ec 40-80%) and amount of struvite in the precipitate (Pp 55-94%) highly varied due to the characteristics of influent wastewaters, particularly to the content of competing elements, such as alkaline and heavy metals and total solids (TS). In particular, Ec (94, 75, 61%) and Pp (76, 66, 48%) decreased at increasing TS (0.57, 0.73, 0.99%), demonstrating the hindering effect of solid content on struvite recovery and quality. According to X-ray diffraction analysis, the structure of all isolated samples corresponded to crystalline, orthorhombic struvite, which exhibited high purity (32-48 g/kgd N, 114-132 g/kgd P, and 99-116 g/kgd Mg) containing only a few foreign elements, whose amount depended on the characteristics of the influent wastewater. All struvite contained other plant macronutrients (K, Ca) and many micronutrients (Fe, Na, Cu, Mn, Co, Zn) that further enhance its agronomic value. Therefore, this study showed that struvite can be successfully recovered from a wide range of highly loaded agroindustrial wastewaters, and that the quality of the recovered struvite could be suitable for reuse in agriculture. PMID- 29455152 TI - Local plant responses to global problems: Dactylis glomerata responses to different traffic pollutants on roadsides. AB - The growing number of road vehicles is a major source of regional and global atmospheric pollution increasing concentrations of CO2 in the air, and levels of metals in air and soil. Nevertheless, the effects of these pollutants on plants growing at roadsides are poorly documented. We carried out an observational study of unmanipulated plants growing by the road, to identify the morpho-physiological responses in a perennial grass Dactylis glomerata. Firstly, we wanted to know the general effect of traffic intensity and ambient CO2 and its interactions on different plant traits. Accordingly, we analyzed the photosynthetic response by field A/Ci Response Curves, SLA, pigment pools, foliar nitrogen, carbohydrates and morphological traits in plants at three distances to the road. Secondly, we wanted to know if Dactylis glomerata plants can accumulate metals present on the roadside (Pb, Zn, Cu, and Sr) in their tissues and rhizosphere, and the effect of these metals on morphological traits. The MANCOVA whole model results shown: 1) a significant effect of road ambient CO2 concentration on morphological traits (not affected by traffic intensity, P interaction CO2 x traffic intensity>0.05), that was mainly driven by a significant negative relationship between the inflorescence number and ambient CO2; 2) a positive and significant relationship between ambient CO2 and the starch content in leaves (unaffected by traffic intensity); 3) a reduction in Jmax (electron transport rate) at high traffic intensity. These lines of evidences suggest a decreased photosynthetic capacity due to high traffic intensity and high levels of ambient CO2. In addition, Pb, Cu, Zn and Sr were detected in Dactylis glomerata tissues, and Cu accumulated in roots. Finally, we observed that Dactylis glomerata individuals growing at the roadside under high levels of CO2 and in the presence of metal pollutants, reduced their production of inflorescences. PMID- 29455153 TI - The recovery of estuarine quality and the perceived increase of cultural ecosystem services by beach users: A case study from northern Spain. AB - In Europe, the quality of coastal bathing waters improved considerably in the last decades, mainly due to the more demanding legislation and the adoption of water sanitation plans. In the Nerbioi estuary (North Spain), the Wastewater Treatment Plan implemented between 1990 and 2001 resulted on an abrupt decrease in microbial concentration; thus, complying with bathing waters legislation and allowing recreational activities again in the three beaches of the estuary. However, little is known about how improvements in bathing waters influences the provision of cultural ecosystem services and human well-being. A questionnaire was used to study beach users' behaviour and perceptions and compared with environmental time-series data (microbial concentration and water transparency). Most respondents perceived an improvement in bathing waters quality and linked it to the estuarine sanitation. Nerbioi beaches are important recreational areas, mainly for local visitors, and water quality improvement was found to be a critical factor for deciding to visit these beaches. Furthermore, most visitors answered that they would not return if water conditions deteriorate. Significant differences existed between beaches, with the most inner beach presenting worse environmental conditions than the other two beaches; and matching user's perceptions. Our findings highlight that water sanitation actions are important for the recovery of degraded coastal environments and for the maintenance of ecosystem services. Also, that multidisciplinary research is necessary to better comprehend the links between environmental recovery and the provision of ecosystem services. PMID- 29455154 TI - Transfemoral thrombectomy in the cavernous sinus and superior ophthalmic vein. AB - Cavernous sinus thrombosis (CST) is a rare condition that can cause death, neurologic disability, and visual loss. A pre-teen with septic CST leading to ocular hypertension and acute visual loss was treated at our institution with thrombectomy and thrombolysis of the cavernous sinuses and superior ophthalmic veins. Successful recanalization of the bilateral cavernous sinuses and superior ophthalmic veins was achieved in two separate procedures without complication. The patient showed immediate symptomatic relief. He was neurologically intact without visual deficits at the 2 month follow-up. This is the first report in the literature showing the feasibility of cavernous sinus thrombectomy using current devices and techniques. Early endovascular therapy may help preserve vision in patients with acute CST. PMID- 29455156 TI - Antisense oligonucleotides and other genetic therapies made simple. AB - Many genetic neurological diseases result from the dysfunction of single proteins. Genetic therapies aim to modify these disease-associated proteins by targeting the RNA and DNA precursors. This review provides a brief overview of the main types of genetic therapies, with a focus on antisense oligonucleotides (ASOs) and RNA interference (RNAi). We use examples of new genetic therapies for spinal muscular atrophy, Duchenne muscular dystrophy and familial amyloid polyneuropathy to highlight the different mechanisms of action of ASOs and RNAi. PMID- 29455155 TI - Newly designed 11-gene panel reveals first case of hereditary amyloidosis captured by massive parallel sequencing. AB - AIMS: Amyloidosis is caused by deposition of abnormal protein fibrils, leading to damage of organ function. Hereditary amyloidosis represents a monogenic disease caused by germline mutations in 11 amyloidogenic precursor protein genes. One of the important but non-specific symptoms of amyloidosis is hypertrophic cardiomyopathy. Diagnostics of hereditary amyloidosis is complicated and the real cause can remain overlooked. We aimed to design hereditary amyloidosis gene panel and to introduce new next-generation sequencing (NGS) approach to investigate hereditary amyloidosis in a cohort of patients with hypertrophic cardiomyopathy of unknown significance. METHODS: Design of target enrichment DNA library preparation using Haloplex Custom Kit containing 11 amyloidogenic genes was followed by MiSeq Illumina sequencing and bioinformatics identification of germline variants using tool VarScan in a cohort of 40 patients. RESULTS: We present design of NGS panel for 11 genes (TTR, FGA, APOA1, APOA2, LYZ, GSN, CST3, PRNP, APP, B2M, ITM2B) connected to various forms of amyloidosis. We detected one mutation, which is responsible for hereditary amyloidosis. Some other single nucleotide variants are so far undescribed or rare variants or represent common polymorphisms in European population. CONCLUSIONS: We report one positive case of hereditary amyloidosis in a cohort of patients with hypertrophic cardiomyopathy of unknown significance and set up first panel for NGS in hereditary amyloidosis. This work may facilitate successful implementation of the NGS method by other researchers or clinicians and may improve the diagnostic process after validation.

PMID- 29455158 TI - American Heart Association's Life's Simple 7 at Middle Age and Prognosis After Myocardial Infarction in Later Life. AB - BACKGROUND: The American Heart Association recommends focusing on 7 health factors (Life's Simple 7) for primordial prevention of cardiovascular health. However, whether greater adherence to Life's Simple 7 in midlife improves prognosis after myocardial infarction (MI) in later life is unknown. METHODS AND RESULTS: In 1277 participants who developed MI during the ARIC (Atherosclerosis Risk in Communities) Study follow-up, a 14-point score of Life's Simple 7 was constructed according to the status (2 points for ideal, 1 point for intermediate, and 0 points for poor) of each of 7 factors (smoking, adiposity, physical activity, diet, total cholesterol, blood pressure, and fasting glucose) at baseline (1987-1989). Hazard ratios for composite and individual adverse outcomes of all-cause mortality, cardiovascular mortality, recurrent MI, heart failure, and stroke were calculated according to Life's Simple 7 score. During a median follow-up of 3.3 years, 918 participants (72%) had subsequent adverse outcomes after MI. Life's Simple 7 score at middle age was inversely associated with adverse outcomes after MI (adjusted hazard ratios of composite outcome, 0.57 [95% confidence interval, 0.39-0.84] if score is >=10, 0.78 [95% confidence interval, 0.57-1.07] if score is 7-9, and 0.82 [95% confidence interval, 0.60 1.11] if score is 4-6 versus <=3). The association was largely independent of access to care and MI severity. Individual factors related to better prognosis after MI were ideal nonsmoking, body mass index, blood pressure, and fasting glucose. CONCLUSIONS: Optimal Life's Simple 7 at middle age was associated with better prognosis after MI in later life. Our findings suggest a secondary prevention benefit of having better cardiovascular health status in midlife. PMID- 29455159 TI - A case of paternal uniparental isodisomy for chromosome 7 associated with overgrowth. AB - BACKGROUND: Paternal uniparental disomy for chromosome 7 (upd(7)pat) is extremely rare, and only four cases have been previously reported. As these cases were accompanied by autosomal-recessive disorders which are likely to be involved in growth restriction, the relevance of upd(7)pat to the overgrowth phenotype remains unclear. Here we describe one case of upd(7)pat with no additional genetic diseases, which may answer the question. METHODS: A 5-year-old Japanese boy presented with a tall stature of unknown causes. To detect the genetic cause of the tall stature, we performed Sanger sequencing, targeted resequencing, comparative genomic hybridisation and single-nucleotide polymorphism (SNP) array analyses, methylation analysis and microsatellite analysis. RESULTS: We could not detect pathogenic variants in causative genes for overgrowth syndrome or apparent copy number alterations. DNA methylation analysis revealed hypomethylation at the GRB10, PEG1 and PEG10 differentially methylated regions. SNP array and microsatellite analyses suggested paternal uniparental isodisomy for chromosome 7. Furthermore, we could not identify homozygous mutations of known causative genes for inherited disorders on chromosome 7. CONCLUSION: We report the first case of upd(7)pat with an overgrowth phenotype. PMID- 29455160 TI - Children and adolescents' experiences of primary lymphoedema: semistructured interview study. AB - BACKGROUND: Congenital lymphoedema is a lifelong condition that has detrimental physical and psychosocial outcomes for young patients and burdensome treatment responsibilities that may hamper patients' motivation for self-management. There is limited research from the perspective of young people with primary lymphoedema. We aimed to describe the experiences and views of children and adolescents with lymphoedema to inform patient-centred practice. METHODS: Twenty patients (aged 8-21 years) with primary lymphoedema were purposively sampled from two paediatric clinics in Sydney, Australia, to participate in a semistructured interview. The transcripts were analysed thematically. RESULTS: We identified six themes: reinforcing abnormality (damaging self-esteem, self-consciousness, frustrating restrictions and isolation); negotiating uncertainties (fearing condition worsening, deprioritised and sidelined, questioning cause and permanence, widespread unawareness); vulnerability and caution (avoiding pain and discomfort, preventing severe and permanent consequences, depending on permission, limiting goals and aspirations); disruptive transition (resisting change, losing progress and support, avoiding treatment costs); developing resilience (focusing on the positives, embracing individuality, recalibrating normality, prioritising coping) and taking responsibility (individualising treatment, needing support, external pressure and motivation, sticking to a routine, seeking independence). CONCLUSION: Children and adolescents learn to adjust to the daily demands of lymphoedema management by individualising and accepting their treatment, but many continue to struggle with their self-esteem and lifestyle restrictions. Strategies are needed to empower young patients to advocate for themselves during their transition to adult care. Treatment plans that minimise social restrictions, address emotional consequences and incorporate patients' preferences could improve adherence, satisfaction and outcomes. PMID- 29455161 TI - Assessing factors associated with long-term work disability after cancer in Belgium: a population-based cohort study using competing risks analysis with a 7 year follow-up. AB - OBJECTIVES: The number of workers with cancer has dramatically increasing worldwide. One of the main priorities is to preserve their quality of life and the sustainability of social security systems. We have carried out this study to assess factors associated with the ability to work after cancer. Such insight should help with the planning of rehabilitation needs and tailored programmes. PARTICIPANTS: We conducted this register-based cohort study using individual data from the Belgian Disability Insurance. Data on 15 543 socially insured Belgian people who entered into the long-term work disability between 2007 and 2011 due to cancer were used. PRIMARY AND SECONDARY OUTCOME MEASURES: We estimated the duration of work disability using Kaplan-Meier and the cause-specific cumulative incidence of ability to work stratified by age, gender, occupational class and year of entering the work disability system for 11 cancer sites using the Fine and Gray model allowing for competing risks. RESULTS: The overall median time of work disability was 1.59 years (95% CI 1.52 to 1.66), ranging from 0.75 to 4.98 years. By the end of follow-up, more than one-third of the disabled cancer survivors were able to work (35%). While a large proportion of the women were able to work at the end of follow-up, the men who were able to work could do so sooner. Being women, white collar, young and having haematological, male genital or breast cancers were factors with the bestlikelihood to be able to return to work. CONCLUSION: Good prognostic factors for the ability to work were youth, woman, white collar and having breast, male genital or haematological cancers. Reviewing our results together with the cancer incidence predictions up to 2025 offers a high value for social security and rehabilitation planning and for ascertaining patients' perspectives. PMID- 29455162 TI - Evaluation of learning from Practical Obstetric Multi-Professional Training and its impact on patient outcomes in Australia using Kirkpatrick's framework: a mixed methods study. AB - OBJECTIVES: The aim of this study was to evaluate the implementation of the Practical Obstetric Multi-Professional Training (PROMPT) simulation using the Kirkpatrick's framework. We explored participants' acquisition of knowledge and skills, its impact on clinical outcomes and organisational change to integrate the PROMPT programme as a credentialing tool. We also aimed to assess participants' perception of usefulness of PROMPT in their clinical practice. STUDY DESIGN: Mixed methods approach with a pre-test/post-test design. SETTING: Healthcare network providing obstetric care in Victoria, Australia. PARTICIPANTS: Medical and midwifery staff attending PROMPT between 2013 and 2015 (n=508); clinical outcomes were evaluated in two cohorts: 2011-2012 (n=15 361 births) and 2014-2015 (n=12 388 births). INTERVENTION: Attendance of the PROMPT programme, a simulation programme taught in multidisciplinary teams to facilitate teaching emergency obstetric skills. MAIN OUTCOME MEASURE: Clinical outcomes compared before and after embedding PROMPT in educational practice. SECONDARY OUTCOME MEASURE: Assessment of knowledge gained by participants through a qualitative analysis and description of process of embedding PROMPT in educational practice. RESULTS: There was a change in the management of postpartum haemorrhage by early recognition and intervention. The key learning themes described by participants were being prepared with a prior understanding of procedures and equipment, communication, leadership and learning in a safe, supportive environment. Participants reported a positive learning experience and increase in confidence in managing emergency obstetric situations through the PROMPT programme, which was perceived as a realistic demonstration of the emergencies. CONCLUSION: Participants reported an improvement of both clinical and non-technical skills highlighting principles of teamwork, communication, leadership and prioritisation in an emergency situation. An improvement was observed in management of postpartum haemorrhage, but no significant change was noted in clinical outcomes over a 2-year period after PROMPT. However, the skills acquired by medical and midwifery staff justify embedding PROMPT in educational programmes. PMID- 29455163 TI - Theory of change for the delivery of talking therapies by lay workers to survivors of humanitarian crises in low-income and middle-income countries: protocol of a systematic review. AB - INTRODUCTION: There is a severe shortage of specialist mental healthcare providers in low-income and middle-income countries (LMICs) affected by humanitarian crises. In these settings, talking therapies may be delivered by non specialists, including lay workers with no tertiary education or formal certification in mental health. This systematic review will synthesise the literature on the implementation and effectiveness of talking therapies delivered by lay workers in LMICs affected by humanitarian crises, in order to develop a Theory of Change (ToC). METHODS AND ANALYSIS: Qualitative, quantitative and mixed methods studies assessing the implementation or effectiveness of lay-delivered talking therapies for common mental disorders provided to adult survivors of humanitarian crises in LMICs will be eligible for inclusion. Studies set in high income countries will be excluded. No restrictions will be applied to language or year of publication. Unpublished studies will be excluded. Seven electronic databases will be searched: MEDLINE, Embase, PsycINFO, PsycEXTRA, Global Health, Cochrane Library and ClinicalTrials.gov. Contents pages of three peer-reviewed journals will be hand-searched. Sources of grey literature will include resource directories of two online mental health networks (MHPSS.net and MHInnovation.net) and expert consultation. Forward and backward citation searches of included studies will be performed. Two reviewers will independently screen studies for inclusion, extract data and assess study quality. A narrative synthesis will be conducted, following established guidelines. A ToC map will be amended iteratively to take into account the review results and guide the synthesis. ETHICS AND DISSEMINATION: Findings will be presented in a manuscript for publication in a peer-reviewed journal and disseminated through a coordinated communications strategy targeting knowledge generators, enablers and users. PROSPERO REGISTRATION NUMBER: CRD42017058287. PMID- 29455164 TI - Surgical efficiency in femtosecond laser cataract surgery compared with phacoemulsification cataract surgery: a case-control study. AB - OBJECTIVES: To investigate differences in surgical time, the distance the surgical instrument travelled and number of movements required to complete manual phacoemulsification cataract surgery versus femtosecond laser cataract surgery. DESIGN: Non-randomised comparative case series. SETTING: Single surgery site, Moorfields Eye Hospital, UK. PARTICIPANTS: 40 cataract surgeries of 40 patients. INTERVENTIONS: Laser-assisted and manual phacoemulsification cataract surgery. Laser-assisted surgery cases were performed using the AMO Catalys platform. PRIMARY AND SECONDARY OUTCOME MEASURES: Computer vision tracking software PhacoTracking were applied to the recordings to establish the distance the instrument travelled, total number of movements (the number of times an instrument stops and starts moving) and time taken for surgery steps including phacoemulsification, irrigation-aspiration (IA) and overall surgery time. The time taken for laser docking and delivery was not included in the analyses. RESULTS: Data on 19 laser-assisted and 19 manual phacoemulsification surgeries were analysed (two cases were excluded due to insufficient video-recording quality). There were no differences in the number of instrument moves, the distance the instrument travelled or time taken to complete the phacoemulsification stage. However for IA, the number of instrument moves (manual: mean 20 (SD 15) vs laser: mean 38 (SD 22), P=0.008) and time taken (manual: mean 75 s (SD 24) vs laser: mean 108 s (SD 36), P=0.003) were significantly greater for laser cases. For laser versus manual cases overall, there was no difference in number of moves or the distance the instrument travelled, but laser cases took longer (mean 88 s, P=0.049). CONCLUSIONS: Laser cataract surgery cases took longer to complete without accounting for the time taken to complete the laser procedure itself. This appears to be in part due to IA requiring more instrument manoeuvres and taking longer to complete. Data from a large randomised series would better elucidate this relationship. PMID- 29455165 TI - Community-deliverable exercise and anxiety in adults with arthritis and other rheumatic diseases: a systematic review with meta-analysis of randomised controlled trials. AB - BACKGROUND/PURPOSE: Given conflicting findings, the purpose of this study was to use the meta-analytic approach to examine the effects of exercise (aerobic, strength training or both) on anxiety in adults with arthritis and other rheumatic diseases (AORD). METHODS: Randomised controlled exercise intervention trials >=4weeks in adults >=18 years of age with osteoarthritis, rheumatoid arthritis or fibromyalgia were included. Studies were located by searching eight electronic databases, cross-referencing and expert review. Dual selection and data abstraction of studies were performed. Hedge's standardised effect size (ES) was calculated for each result and pooled using the recently developed inverse heterogeneity model. Two-tailed z-alpha values <=0.05 and non-overlapping 95% CI were considered statistically significant. Heterogeneity was estimated using Q and I2 with alpha values <=0.10 for Q considered statistically significant. Small study effects were examined using funnel plots and Egger's regression test. In addition, the number needed to treat (NNT), percentile improvement and meta regression were conducted. RESULTS: Of the 639 citations screened, 14 studies representing 926 initially enrolled participants (539 exercise, 387 control) met the criteria for inclusion. Length of training (mean+/-SD) averaged 15.8+/-6.7 weeks, frequency 3.3+/-1.3 times per week and duration 28.8+/-14.3 min per session. Overall, statistically significant reductions in anxiety were found (exercise minus control changes ES=-0.40, 95% CI -0.65 to -0.15, tau2=0.14; Q=40.3, P=0.0004; I2 =62.8%). The NNT was 6 with a percentile improvement of 15.5% and an estimated 5.3 million inactive US adults with AORD improving their anxiety if they started exercising regularly. Statistically significant small study effects were observed (P<0.0001). CONCLUSIONS: Exercise is associated with reductions in anxiety among adults with selected types of AORD. However, a need exists for additional, well-designed, randomised controlled trials on this topic. PROSPERO REGISTRATION NUMBER: CRD42016048728. PMID- 29455166 TI - The development of an online intervention (Care Assist) to support male caregivers of women with breast cancer: a protocol for a mixed methods study. AB - INTRODUCTION: It is projected that 17 730 women will be diagnosed with breast cancer in Australia in 2017, with 3114 of these predicted to be fatal. Caregiving for a person with cancer can significantly impact caregivers' physical and mental health. Many caregivers feel ill-prepared for this role, especially when care involves complex medical needs accompanied by the psychological challenges experienced following a cancer diagnosis. METHODS AND ANALYSIS: This study employs a convergent, parallel, mixed methods design combining an online survey with an optional interview. Eligible, consenting participants will be invited to participate in a survey to examine (1) participants' unmet needs, (2) challenges experienced throughout the cancer journey, (3) perceived self-efficacy to determine participants' level of confidence in undertaking caregiver tasks, (4) views regarding suitable content to include in a caregiver training intervention, (5) preferred method of intervention delivery (ie, website, smartphone application and/or interactive video), and (6) preferences for the timing of delivery of the intervention content (ie, ability to choose a module, access to the entire content or have a set order in which they receive the information). Caregivers will be eligible to participate if they (1) are male, (2) have previously cared for or are currently caring for a woman with breast cancer, (3) are aged over 18 years, and (4) do not currently suffer from a cognitive impairment or mental health condition (ie, depression, anxiety). Data analysis will include examination of differences in psychological outcomes and needs based on demographic variables, and mediation analysis to explore whether self-efficacy mediates the relationship between challenges, unmet needs and distress. Qualitative data will be analysed using thematic analysis. ETHICS AND DISSEMINATION: The study was reviewed and approved by two human research ethics committees within Australia. We anticipate two to three publications may be developed from the study. PMID- 29455167 TI - Pulmonary metastasis in rectal cancer: a retrospective study of clinicopathological characteristics of 404 patients in Chinese cohort. AB - OBJECTIVES: This study aim to investigate the incidence, timing and risk factors of metachronous pulmonary recurrence after curative resection in patients with rectal cancer. DESIGN: A retrospective cohort study. SETTING: This study was conducted at a tertiary referral cancer hospital. PARTICIPANTS: A total of 404 patients with rectal cancer who underwent curative resection from 2007 to 2012 at Beijing Hospital were enrolled in this study. INTERVENTIONS: The pattern of recurrence was observed and evaluated. PRIMARY AND SECONDARY OUTCOME MEASURES: The incidence and timing of recurrences by site were calculated, and the risk factors of pulmonary recurrence were analysed. RESULTS: The 5-year disease-free survival for the entire cohort was 77.0%. The most common site of recurrence was the lungs, with an incidence of 11.4%, followed by liver. Median interval from rectal surgery to diagnosis of pulmonary recurrence was much longer than that of hepatic recurrence (20 months vs 10 months, P=0.022). Tumour location, pathological tumor-node-metastasis (TNM) stage and positive circumferential resection margin were identified as independent risk factors for pulmonary recurrence. A predictive model based on the number of risk factors identified on multivariate analysis was developed, 5-year pulmonary recurrence-free survival for patients with 0, 1, 2 and 3 risk factors was 100%, 90.4%, 77.3% and 70.0%, respectively (P<0.001). CONCLUSIONS: This study emphasised that the lung was the most common site of metachronous metastasis in patients with rectal cancer who underwent curative surgery. For patients with unfavourable risk profiles, a more intensive surveillance programme that could lead to the early detection of recurrence is strongly needed. PMID- 29455168 TI - Experiences of Australian men diagnosed with advanced prostate cancer: a qualitative study. AB - OBJECTIVE: To explore men's lived experience of advanced prostate cancer (PCa) and preferences for support. DESIGN: Cross-sectional qualitative study applying open-ended surveys and interviews conducted between June and November 2016. Interviews audio-recorded and transcribed verbatim and analysed from an interpretive phenomenological perspective. SETTING: Australia, nation-wide. PARTICIPANTS: 39 men diagnosed with advanced PCa (metastatic or castration resistant biochemical regression) were surveyed with 28 men subsequently completing a semistructured in depth telephone interview. RESULTS: Thematic analysis of interviews identified two organising themes: lived experience and supportive care. Lived experience included six superordinate themes: regret about late diagnosis and treatment decisions, being discounted in the health system, fear/uncertainty about the future, acceptance of their situation, masculinity and treatment effects. Supportive care included five superordinate themes: communication, care coordination, accessible care, shared experience/peer support and involvement of their partner/family. CONCLUSIONS: Life course and the health and social context of PCa influence men's experiences of advanced disease. Multimodal interventions integrating peer support and specialist nurses are needed that more closely articulate with men's expressed needs. PMID- 29455169 TI - Positron emission tomography (PET) for prediction of glioma histology: protocol for an individual-level data meta-analysis of test performance. AB - INTRODUCTION: Gliomas, the most commonly diagnosed primary brain tumours, are associated with varied survivals based, in part, on their histological subtype. Therefore, accurate pretreatment tumour grading is essential for patient care and clinical trial design. METHODS AND ANALYSIS: We will perform an individual-level data meta-analysis of published studies to evaluate the ability of different types of positron emission tomography (PET) to differentiate high from low-grade gliomas. We will search PubMed and Scopus from inception through 30 July 2017 with no language restriction and full-text evaluation of potentially relevant articles. We will choose studies that assess PET using 18-Fludeoxyglucose (18F FDG), l-[Methyl-()11C]Methionine (11C-MET), 18F-Fluoro-Ethyl-Tyrosine (18F-FET) or (18)F-Fluorothymidine (18F-FLT)for grading, verified with histological confirmation. We will include both prospective and retrospective studies. Bias will be assessed by two reviewers with the Quality Assessment of Diagnostic Accuracy Studies-2 tool and as per method described by Deeks et al. ETHICS AND DISSEMINATION: Ethics approval was not applicable, as this is a meta-analytic study. Results of the analysis will be submitted for publication in a peer reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42017078649. PMID- 29455170 TI - Comparison and validation of screening tools for substance use in pregnancy: a cross-sectional study conducted in Maryland prenatal clinics. AB - INTRODUCTION: Prescription-drug use in the USA has increased by more than 60% in the last three decades. Prevalence of prescription-drug use among pregnant women is currently estimated around 50%. Prevalence of illicit drug use in the USA is 14.6% among pregnant adolescents, 8.6% among pregnant young adults and 3.2% among pregnant adults. The first step in identifying problematic drug use during pregnancy is screening; however, no specific substance-use screener has been universally recommended for use with pregnant women to identify illicit or prescription-drug use. This study compares and validates three existing substance use screeners for pregnancy-4 P's Plus, National Institute on Drug Abuse (NIDA) Quick Screen/Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) and the Substance Use Risk Profile-Pregnancy (SURP-P) scale. METHODS AND ANALYSIS: This is a cross-sectional study designed to evaluate the sensitivity, specificity and usability of existing substance-use screeners. Recruitment occurs at two obstetrics clinics in Baltimore, Maryland, USA. We are recruiting 500 participants to complete a demographic questionnaire, NIDA Quick Screen/ASSIST, 4 P's Plus and SURP-P (ordered randomly) during their regularly scheduled prenatal appointment, then again 1 week later by telephone. Participants consent to multidrug urine testing, hair drug testing and allowing access to prescription drug and birth outcome data from electronic medical records. For each screener, reliability and validity will be assessed. Test-retest reliability analysis will be conducted by examining the results of repeated screener administrations within 1 week of original screener administrations for consistency via correlation analysis. Furthermore, we will assess if there are differences in the validity of each screener by age, race and trimester.

PMID- 29455171 TI - Visual-motor integration and fine motor skills at 61/2 years of age and associations with neonatal brain volumes in children born extremely preterm in Sweden: a population-based cohort study. AB - OBJECTIVES: This exploratory study aimed to investigate associations between neonatal brain volumes and visual-motor integration (VMI) and fine motor skills in children born extremely preterm (EPT) when they reached 61/2 years of age. SETTING: Prospective population-based cohort study in Stockholm, Sweden, during 3 years. PARTICIPANTS: All children born before gestational age, 27 weeks, during 2004-2007 in Stockholm, without major morbidities and impairments, and who underwent MRI at term-equivalent age. MAIN OUTCOME MEASURES: Brain volumes were calculated using morphometric analyses in regions known to be involved in VMI and fine motor functions. VMI was assessed with The Beery-Buktenica Developmental Test of Visual-Motor Integration-sixth edition and fine motor skills were assessed with the manual dexterity subtest from the Movement Assessment Battery for Children-second edition, at 61/2 years. Associations between the brain volumes and VMI and fine motor skills were evaluated using partial correlation, adjusted for total cerebral parenchyma and sex. RESULTS: Out of 107 children born at gestational age <27 weeks, 83 were assessed at 61/2 years and 66/83 were without major brain lesions or cerebral palsy and included in the analyses. A representative subsample underwent morphometric analyses: automatic segmentation (n=34) and atlas-based segmentation (n=26). The precentral gyrus was associated with both VMI (r=0.54, P=0.007) and fine motor skills (r=0.54, P=0.01). Associations were also seen between fine motor skills and the volume of the cerebellum (r=0.42, P=0.02), brainstem (r=0.47, P=0.008) and grey matter (r= 0.38, P=0.04). CONCLUSIONS: Neonatal brain volumes in areas known to be involved in VMI and fine motor skills were associated with scores for these two functions when children born EPT without major brain lesions or cerebral palsy were evaluated at 61/2 years of age. Establishing clear associations between early brain volume alterations and later VMI and/or fine motor skills could make early interventions possible. PMID- 29455174 TI - Bladder necrosis: 'A man without a bladder'. AB - Since the use of antibiotics, bladder necrosis has become a rare condition. We report a case of bladder necrosis in a 90-year-old man following urinary retention. After insertion of a transurethral catheter (TUC), 2 L of urine was evacuated. In the following days, the TUC became intermittently blocked. Adequate bladder drainage could not be obtained despite intensive rinsing and placement of a suprapubic catheter. On surgical exploration necrosis of almost the entire bladder wall, except for the trigone, was encountered. Surgical debridement of the non-viable bladder wall without opening the abdominal cavity was conducted, and a TUC was placed in the Retzius cavity to ensure evacuation of urine. Since the patient was haemodynamically unstable, construction of a urinary diversion was waived and urinary drainage of the Retzius cavity by the TUC was accepted, resulting in adequate urinary drainage without compromising renal function. PMID- 29455172 TI - Transmission of ESBL-producing Enterobacteriaceae and their mobile genetic elements-identification of sources by whole genome sequencing: study protocol for an observational study in Switzerland. AB - INTRODUCTION: Extended-spectrum beta-lactamases (ESBL)-producing Enterobacteriaceae were first described in relation with hospital-acquired infections. In the 2000s, the epidemiology of ESBL-producing organisms changed as especially ESBL-producing Escherichia coli was increasingly described as an important cause of community-acquired infections, supporting the hypothesis that in more recent years ESBL-producing Enterobacteriaceae have probably been imported into hospitals rather than vice versa. Transmission of ESBL-producing Enterobacteriaceae is complicated by ESBL genes being encoded on self transmissible plasmids, which can be exchanged among the same and different bacterial species. The aim of this research project is to quantify hospital-wide transmission of ESBL-producing Enterobacteriaceae on both the level of bacterial species and the mobile genetic elements and to determine if hospital-acquired infections caused by ESBL producers are related to strains and mobile genetic elements predominantly circulating in the community or in the healthcare setting. This distinction is critical in prevention since the former emphasises the urgent need to establish or reinforce antibiotic stewardship programmes, and the latter would call for more rigorous infection control. METHODS AND ANALYSIS: This protocol presents an observational study that will be performed at the University Hospital Basel and in the city of Basel, Switzerland. ESBL-producing Enterobacteriaceae will be collected from any specimens obtained by routine clinical practice or by active screening in both inpatient and outpatient settings, as well as from wastewater samples and foodstuffs, both collected monthly over a 12-month period for analyses by whole genome sequencing. Bacterial chromosomal, plasmid and ESBL-gene sequences will be compared within the cohort to determine genetic relatedness and migration between humans and their environment. ETHICS AND DISSEMINATION: This study has been approved by the local ethics committee (Ethikkommission Nordwest-und Zentralschweiz) as a quality control project (Project-ID 2017-00100). The results of this study will be published in peer-reviewed medical journals, communicated to participants, the general public and all relevant stakeholders. PMID- 29455175 TI - When a polyp is not a polyp: incidental finding of a sigmoid schwannoma at first colonoscopic screening. AB - Schwannomas, peripheral nerve sheath tumours arising from Schwann cells, are often associated with inherited disorders such as neurofibromatosis. Gastrointestinal schwannomas, while rare, have been reported in those without personal or family history of neurofibromatosis. Diagnoses of these lesions, however, typically follow evaluations prompted by symptomatic presentations associated with abdominal pain, rectal bleeding, change in bowel habits or positive results on faecal occult blood tests performed for colorectal cancer screening. Further, management of these predominantly benign lesions commonly incorporates surgical resection. We present the case of a sigmoid schwannoma found in an asymptomatic individual on first screening colonoscopy and treated with complete endoscopic polypectomy with anticipated surveillance colonoscopy. PMID- 29455176 TI - Late diagnosis: a case of rapidly progressive extranodal NK/T cell lymphoma, nasal type. AB - Extranodal natural killer (NK)/T cell lymphoma, nasal type is a condition that has poor prognosis. Accurate diagnosis of lymphoma is made by pathological findings. We report a case of extranodal NK/T cell lymphoma, nasal type affecting the lung and liver and which was difficult to diagnose because of negative biopsy results from multiple sites. A 39-year-old man who had dry cough and fever for 1 month was referred to our hospital. He had pancytopenia and elevated serum levels of lactate dehydrogenase and soluble interleukin-2 receptor. Hepatosplenomegaly and multiple lung nodules were found on imaging study. Specimens of bronchoscopic lung, percutaneous liver, bone marrow and random skin biopsies were all negative. Open lung biopsy was not definitive. Unfortunately, disease progression was rapid and fatal before results of pleural fluid cytology and a second liver biopsy showed extranodal NK/T cell lymphoma, nasal type. This report focused on diagnostic planning for rapidly progressive extranodal NK/T-cell lymphoma, nasal type. PMID- 29455177 TI - NMDAR (N-methyl-D-aspartate receptor) encephalitis in a patient with MS (multiple sclerosis): a rare and challenging case. AB - We present a rare case of N-methyl-D-aspartate receptor (NMDAR) encephalitis in a 41-year-old Caucasian woman, who initially presented with prominent neuropsychiatric symptoms on the background of pre-existing multiple sclerosis. Here, the authors navigate the muddy water between neurology and psychiatry, describing the caveats of antibody testing with a misdiagnosed case of acute and transient psychotic episode. NMDAR encephalitis in MS is a rare condition, which can be easily confused with a new onset psychotic episode. This case report can be helpful in recognition and diagnosis of this rare condition. Making the right diagnosis is important since it can prevent an unnecessary radical treatment and long-term neuropsychiatric complications. PMID- 29455178 TI - Disabling pansclerotic morphoea of childhood. AB - Disabling pansclerotic morphoea (DPM) of childhood is a severe and often fatal variant of deep morphoea. It usually starts in childhood and rarely seen in adults. The course of the disease is progressive with lifelong morbidity in the form of joint contractures and immobility. The causes of mortality include complications such as sepsis, gangrene and cardiopulmonary involvement. Herein, we discuss the case of a 15-year-old girl with limb deformity and finger contractures, that is, bone involvement. The diagnosis of DPM of childhood was fortuitously made after the correction of limb deformity, when the patient was seen in the dermatology department for evaluation of skin discolouration on the thighs. PMID- 29455179 TI - A quintessential syndrome with a rare marvelling aetiology: Rosai-Dorfman disease presenting as Conus-Cauda syndrome. AB - A 19-year-old woman presented with a history of severe lower backache and asymmetric proximal lower limb weakness during the past 3 months. In addition, she also suffered from lower motor neuron-type bladder and bowel symptoms. On examination, paraparesis was noted. Further, sensory examination suggested patchy asymmetric sensory loss in both lower limbs with saddle anaesthesia and areflexia. A clinical diagnosis of Conus-Cauda syndrome was made and contrast enhanced MRI of the lumbar and sacral spine was done, which confirmed the presence of a mass lesion within the spinal canal involving the cauda equina extending up to the sacral level. She underwent partial resection of the lesion following which the neurological deficits and lower backache resolved. Histopathological evaluation and immunohistochemical analyses uncovered Rosai Dorfman disease. There was no evidence of disease elsewhere in the body. Since the patient improved significantly following surgery and exhibited no further neurological worsening, she remains under close follow-up. PMID- 29455180 TI - Takotsubo syndrome in a premenopausal patient. AB - Takotsubo syndrome is a rare clinical condition, with a pathophysiology that is not fully understood. Characterised by an acute and usually reversible heart failure, the condition is often preceded by a stressful event. For the diagnosis of Takotsubo syndrome to be possible, the absence of coronary artery disease as a cause is required. We report a case of Takotsubo syndrome in a 47-year-old woman of fertile age. Electrical and echocardiographic presentations were classical in the patient. However, abnormally elevated cardiac biomarkers were registered. The patient showed signs of clinical improvement, with a follow-up angiography excluding coronary artery disease and therefore leading to a diagnosis of Takotsubo syndrome. PMID- 29455181 TI - A child with tubulointerstitial nephritis and uveitis (TINU) syndrome. AB - Tubulointerstitial nephritis and uveitis syndrome is an uncommon disease, probably underdiagnosed in clinical practice. Its aetiology and pathogenesis remain unknown. This syndrome is defined by an association of uveitis and tubulointerstitial nephritis, with no evidence of systemic disease or infection that might cause both ocular and renal inflammation. Renal and ocular manifestations may not occur simultaneously, making the diagnosis even more challenging. Treatment includes topical and oral corticosteroids. Renal involvement usually resolves spontaneously with full recovery of kidney function, however uveitis can persist or recur years after its initial presentation. We report a case of a 13-year-old girl with tubulointerstitial nephritis and uveitis syndrome. PMID- 29455182 TI - Pulmonary inflammatory myofibroblastic tumour misdiagnosed as a round pneumonia. PMID- 29455183 TI - The effect of lncRNA HOTAIR on chemoresistance of ovarian cancer through regulation of HOXA7. AB - This study aimed at investigating the biological functions of long non-coding RNAs (lncRNAs) hox transcript antisense intergenic RNA (HOTAIR) in resistant ovarian cancer cells, exploring the regulation effect of HOTAIR on HOXA7, and investigating their influence on the chemosensitivity of ovarian cancer cells. Quantitative real-time polymerase chain reaction (qRT-PCR) was applied for the verification of HOTAIR expression in resistant and sensitive groups. How HOTAIR downregulation affected cell proliferation, migration and invasion, and apoptosis were determined using the MTT assay and the colony formation assay, the Transwell assay and flow cytometry analysis, respectively. Immunohistochemistry was used to inspect the protein expression of HOXA7 in resistant and sensitive ovarian cancer tissues. The regulation relationship between HOTAIR and HOXA7 was investigated by qRT-PCR and Western blot. The effect of HOTAIR and HOXA7 on tumor growth was confirmed by the tumor xenograft model of nude mice. By knocking down HOXA7, HOTAIR downregulation restrained the ovarian cancer deterioration in functional experiments. Silencing of HOTAIR and HOXA7 could effectively inhibit tumor growth and increase chemosensitivity of ovarian tumors in nude mice. Downregulation of HOTAIR negatively affected the survival and activity of resistant ovarian cancer cells, and suppressed the expression of HOXA7. Silencing of HOTAIR and HOXA7 could increase the chemosensitivity of ovarian cancer cells, thus suppressing tumor development. PMID- 29455184 TI - CSF free light chain identification of demyelinating disease: comparison with oligoclonal banding and other CSF indexes. AB - BACKGROUND: Cerebrospinal fluid (CSF) used in immunoglobulin gamma (IgG) index testing and oligoclonal bands (OCBs) are common laboratory tests used in the diagnosis of multiple sclerosis. The measurement of CSF free light chains (FLC) could pose as an alternative to the labor-intensive isoelectric-focusing (IEF) gels used for OCBs. METHODS: A total of 325 residual paired CSF and serum specimens were obtained after physician-ordered OCB IEF testing. CSF kappa (cKFLC) and lambda FLC (cLFLC), albumin and total IgG were measured. Calculations were performed based on combinations of analytes: CSF sum of kappa and lambda ([cKFLC+cLFLC]), kappa-index (K-index) ([cKFLC/sKFLC]/[CSF albumin/serum albumin]), kappa intrathecal fraction (KFLCIF) {([cKFLC/sKFLC]-[0.9358*CSF albumin/serum albumin]^[0.6687*sKFLC]/cKFLC)} and IgG-index ([CSF IgG/CSF albumin]/[serum IgG/serum albumin]). RESULTS: Patients were categorized as: demyelination (n=67), autoimmunity (n=53), non-inflammatory (n=50), inflammation (n=38), degeneration (n=28), peripheral neuropathy (n=24), infection (n=13), cancer (n=11), neuromyelitis optica (n=10) and others (n=31). cKFLC measurement used alone at a cutoff of 0.0611 mg/dL showed >90% agreement to OCBs, similar or better performance than all other calculations, reducing the number of analytes and variables. When cases of demyelinating disease were reviewed, cKFLC measurements showed 86% clinical sensitivity/77% specificity. CONCLUSIONS: cKFLC alone demonstrates comparable performance to OCBs along with increased sensitivity for demyelinating diseases. Replacing OCB with cKFLC would alleviate the need for serum and CSF IgG and albumin and calculated conversions. cKFLC can overcome challenges associated with performance, interpretation, and cost of traditional OCBs, reducing costs and maintaining sensitivity and specificity supporting MS diagnosis. PMID- 29455185 TI - Performance evaluation of cobas HBV real-time PCR assay on Roche cobas 4800 System in comparison with COBAS AmpliPrep/COBAS TaqMan HBV Test. AB - BACKGROUND: Hepatitis B virus (HBV) nucleic acid amplification testing (NAAT) is important for the diagnosis and management of HBV infection. We evaluated the analytical performance of the cobas HBV NAAT (Roche Diagnostics GmbH, Mannheim, Germany) on the cobas 4800 System in comparison with COBAS AmpliPrep/COBAS TaqMan HBV Test (CAP/CTM HBV). METHODS: Precision was evaluated using three levels of cobas HBV/HCV/HIV-1 Control Kit, and linearity was evaluated across the anticipated measuring range (10.0-1.0*109 IU/mL) at seven levels using clinical samples. Detection capability, including limit of blank (LOB), limit of detection (LOD) and limit of quantitation (LOQ), was verified using the 4th WHO International Standard for HBV DNA for NAT (NIBSC code: 10/266). Correlation between the two systems was compared using 205 clinical samples (102 sera and 103 EDTA plasma). RESULTS: Repeatability and total imprecision (coefficient of variation) ranged from 0.5% to 3.8% and from 0.5% to 3.5%, respectively. Linearity (coefficient of determination, R2) was 0.999. LOB, LOD and LOQ were all acceptable within the observed proportion rate (85%). Correlation was very high between the two systems in both serum and plasma samples (correlation coefficient [r]=0.995). CONCLUSIONS: The new cobas HBV real-time PCR assay on the cobas 4800 System showed reliable analytical performances.

AB - Physiological hemostasis is an intricate biological system, where procoagulant and anticoagulant forces interplay and preserves blood fluidity when blood vessels are intact, or trigger clot formation to prevent excessive bleeding when blood vessels are injured. The modern model of hemostasis is divided into two principal phases. The first, defined as primary hemostasis, involves the platelet vessel interplay, whilst the second, defined as secondary hemostasis, mainly involves coagulation factors, damaged cells and platelet surfaces, where the so called coagulation cascade rapidly develops. The activation and amplification of the coagulation cascade is finely modulated by the activity of several physiological inhibitors. Once bleeding has been efficiently stopped by blood clot formation, dissolution of the thrombus is essential to restore vessel permeability. This process, known as fibrinolysis, also develops through coordinate action of a vast array of proteins and enzymes. An accurate diagnosis of hemostasis disturbance entails a multifaceted approach, encompassing family and personal history of hemostatic disorders, accurate collection of clinical signs and symptoms, integrated with laboratory hemostasis testing. Regarding laboratory testing, a reasonable approach entails classifying hemostasis testing according to cost, complexity and available clinical information. Laboratory workout may hence initiate with some rapid and inexpensive "screening" tests, characterized by high negative predictive value, then followed by second- or third-line analyses, specifically aimed to clarify the nature and severity of bleeding or thrombotic phenotype. This article aims to provide a general overview of the hemostatic process, and to provide some general suggestions to optimally facilitate laboratory hemostasis testing.

PMID- 29455190 TI - A novel paraneoplastic syndrome with acquired lipodystrophy and chronic inflammatory demyelinating polyneuropathy in an adolescent male with craniopharyngioma. AB - BACKGROUND: Acquired lipodystrophy, craniopharyngioma and chronic inflammatory demyelinating polyneuropathy (CIDP) are individually rare disorders, and have never before been reported in a single patient. CASE PRESENTATION: A 15-year-7 month old Caucasian male presented with lower extremity weakness, frequent falls and abnormal fat distribution occurring over the previous 1 year. He was diagnosed with CIDP, craniopharyngioma and acquired lipodystrophy. The patient underwent tumor debulking and cranial irradiation for the craniopharyngioma, and received monthly intravenous immunoglobulin for the CIDP. The patient initially had some resolution of the lipodystrophy phenotype, but subsequently the abnormal fat distribution recurred and the patient developed additional systemic abnormalities, including mild pancytopenia and hepatic fibrosis. CONCLUSIONS: Our patient represents a novel association of acquired lipodystrophy, craniopharyngioma, and CIDP, possibly due to an as yet unidentified paraneoplastic autoantibody. PMID- 29455191 TI - Smith-Lemli-Opitz syndrome: clinical and biochemical correlates. AB - BACKGROUND: Smith-Lemli-Opitz syndrome (SLOS) is an autosomal recessive disorder caused by mutations in the DHCR7 gene that result in reduced cholesterol biosynthesis. The aim of the study was to examine the biochemical and clinical features of SLOS in the context of the emerging evidence of the importance of cholesterol in morphogenesis and steroidogenesis. METHODS: We retrospectively reviewed the records of 18 patients (including four fetuses) with confirmed SLOS and documented their clinical and biochemical features. RESULTS: Seven patients had branchial arch abnormalities, including micrognathia, immune dysfunction and hypocalcemia. Thymic abnormalities were found in three fetuses. All four patients with a cholesterol level of <=0.35 mmol/L died. They all had electrolyte abnormalities (hyperkalemia, hyponatremia, hypocalcemia), necrotizing enterocolitis, sepsis-like episodes and midline defects including the branchial and cardiac defects. Patients with cholesterol levels >=1.7 mmol/L had milder features and were diagnosed at 9 months to 25 years of age. All 10 patients had intellectual disability. One patient was found to have a novel mutation, c.1220A>G (p.Asn407Ser). CONCLUSIONS: We suggest that screening for adrenal insufficiency and for hypoparathyroidism, hypothyroidism and immunodeficiency, should be done routinely in infants diagnosed early with SLOS. Early diagnosis and intervention to correct these biochemical consequences may decrease mortality and improve long-term outcome in these patients. PMID- 29455192 TI - Cloning and expression analysis of cDNAs encoding ADP-glucose pyrophosphorylase large and small subunits from hulless barley (Hordeum vulgare L. var. nudum). AB - As an important plateau cereal crop, hulless barley is the principal food for the Tibetan people in China. ADP-glucose pyrophosphorylase (AGPase) is considered as the key enzyme for starch biosynthesis in plants. In this study, cDNAs encoding the small subunit (SSU I) and large subunit (LSU I) of AGPase were isolated from hulless barley. The results showed that SSU I and LSU I were 1438 and 1786 bp in length with a complete open reading frame (ORF) of 1419 and 1572 bp. The ORF encoded polypeptides of 472 and 523 amino acids were having calculated molecular masses of 52.01 and 58.23 kDa, and the pI values were 5.59 and 6.30. In addition, phylogenetic analysis showed that SSU I and LSU I had the same phylogenetic trends with some species. Furthermore, expression levels in different growth periods and tissues of two hulless barley varieties were analyzed by quantitative reverse transcription-polymerase chain reaction. Gene expression levels of SSU I and LSU I were consistent with the total starch accumulation rate in endosperm. In conclusion, our data confirmed that SSU I and LSU I played an important role in hulless barley starch synthesis. PMID- 29455193 TI - Growth Trajectory in Children with Type 1 Diabetes Mellitus: The Impact of Insulin Treatment and Metabolic Control. AB - BACKGROUND: Linear growth was reported to be negatively affected by type 1 diabetes mellitus (T1DM), in relation to disease duration and poor metabolic control. It is unclear whether a subtle growth failure still persists despite the optimization of therapy. Our aim was to analyse pubertal growth, adult height, and metabolic profile in a cohort of children with T1DM undergoing intensive insulin treatment by multiple daily injections or continuous subcutaneous insulin infusion (CSII). METHODS: One-hundred and four children (51 males) with prepubertal onset of T1DM were prospectively followed up to final height attainment. RESULTS: Age at puberty onset was 11.7 +/- 1.1 years in males and 10.9 +/- 1.3 in females. Age at adult height attainment was 16.4 +/- 1.6 years in males and 14.1 +/- 1.8 years in females. Pubertal height gain was 24.4 +/- 4.9 cm in males and 19.0 +/- 3.8 cm in females. HbA1c, HDL cholesterol, and triglyceride levels increased during puberty. HDL cholesterol levels were higher in patients treated with CSII. Height standard deviation score (SDS) at diagnosis (0.52 +/- 1.04) was higher than target height SDS (0.01 +/- 1.07), but declined afterwards, and both height SDS at puberty onset (0.22 +/- 1.1) and adult height SDS (-0.1 +/ 1.02) were not significantly different from target height SDS. BMI SDS showed a positive trend from diagnosis to puberty onset and stabilized later (-0.04 +/- 1.4 at T1DM onset, 0.55 +/- 2.1 at puberty onset, and 0.53 +/- 2.1 at adult height attainment). CONCLUSIONS: Although subtle abnormalities of growth still persist, the modern advancements of insulin therapy are able to normalize puberty and final height of children with T1DM.

AB - BACKGROUND/AIMS: We aimed to evaluate the incidence and characteristics of adrenal crisis in Japanese children with 21-hydroxylase deficiency (21-OHD). METHODS: We conducted a retrospective nationwide survey for the councilors of the Japanese Society for Pediatric Endocrinology (JSPE) regarding adrenal crisis in children under 7 years with 21-OHD, admitted to hospitals from 2011 through 2016. We defined adrenal crisis as the acute impairment of general health due to glucocorticoid deficiency with at least two of symptoms, signs, or biochemical abnormalities. RESULTS: The councilors of the JSPE in 83 institutions responded to this survey (response rate, 60.1%). Data analyses of 378 patients with 1,101.4 person-years (PYs) revealed that 67 patients (17.7%) experienced at least 1 episode of hospital admission for adrenal crisis at the median age of 2 years. The incidence of adrenal crisis was calculated as 10.9 per 100 PYs (95% confidence interval [CI] 9.6-12.2). Infections were the most common precipitating factors, while no factor was observed in 12.5%. Hypoglycemia occurred concomitantly in 27.4%. One patient died from severe hypoglycemia, resulting in a mortality rate of 0.09 per 100 PYs (95% CI 0.0-0.2). CONCLUSION: Adrenal crisis is not rare and can be accompanied by disastrous hypoglycemia in children with 21 OHD. PMID- 29455196 TI - The Relationship between Hypomagnesemia and Pulmonary Function Tests in Patients with Chronic Asthma. AB - OBJECTIVE: To investigate the relationship between serum values of magnesium and the parameters of the pulmonary function tests (PFT) in patients with chronic asthma. SUBJECTS AND METHODS: This study recruited 50 patients with chronic stable asthma and 40 healthy individuals as a control group. Data on age, sex, severity of asthma, PFT, and details of drug therapy were obtained from each group. Serum magnesium, potassium, phosphorus, calcium, and sodium levels were also measured. To evaluate differences between groups, the Student t test or Mann Whitney U test was performed for continuous variables, and the chi2 test for categorical variables. RESULTS: In the asthma group, 10% (n = 9) of the patients had hypomagnesemia and 5.5% (n = 5) had hypophosphatemia. Patients with asthma were divided into two groups: the hypomagnesemic group (n = 9) and the normomagnesemic group (n = 41). Forced expiratory volume in 1 s (FEV1), FEV1%, peak expiratory flow (PEF), and PEF% were lower in the hypomagnesemic group than in the normomagnesemic group (p = 0.02). Multiple logistic regression analysis revealed a statistically significant association between hypomagnesemia and PFT in the hypomagnesemic asthmatic group. The correlations of age with FEV1, FEV1%, PEF, and PEF% were as follows: p = 0.00, r = 0.29; p = 0.00, r = 0.43; p = 0.03, r = 0.22; p = 0.00, r = 0.38; and p = 0.03, r = 0.22, respectively. The correlation of serum magnesium levels with PFT (FEV1, FEV1%, PEF, PEF%) were as follows: p = 0.001, r = 0.29; p = 0.001, r = 0.43; p = 0.03, r = 0.22; and p = 0.001, r = 0.38, respectively. The other electrolytes were within the normal range in both groups. CONCLUSION: In this study, hypomagnesemia and hypophosphatemia were found to be the most common electrolyte abnormalities in patients with chronic stable asthma. FEV1, FEV1%, PEF, and PEF% were significantly lower in asthmatic patients with hypomagnesemia compared to asthmatic patients with normomagnesemia. PMID- 29455198 TI - Incidence, Survival, and Risk Factors for Adults with Acute Myeloid Leukemia Not Otherwise Specified and Acute Myeloid Leukemia with Recurrent Genetic Abnormalities: Analysis of the Surveillance, Epidemiology, and End Results (SEER) Database, 2001-2013. AB - BACKGROUND/AIM: As the knowledgebase of acute myeloid leukemia (AML) has grown, classification systems have moved to incorporate these new findings. METHODS: We assessed 32,941 patients with AML whose records are contained in the Surveillance, Epidemiology, and End Results (SEER) database. RESULTS: Half of all patients diagnosed between 2001 and 2013 did not have a World Health Organization (WHO) classification. Acute promyelocytic leukemia and acute panmyelosis with myelofibrosis were associated with the longest leukemia-specific survival (110 and 115 months, respectively), and AML with minimal differentiation and acute megakaryoblastic leukemia with the shortest (30 and 28 months, respectively). For patients in the WHO groups AML not otherwise specified (AML-NOS) and AML with recurrent genetic abnormalities (AML-RGA), the risk of death was greater for older patients and less for married patients. Black patients with any type of AML NOS also had a higher risk of death. Patients whose case of AML did not receive a WHO classification were older and this group had a higher risk of death when compared to patients with a WHO type of AML-NOS. CONCLUSION: Our findings highlight the divergent outcomes of patients with AML and the importance of using the WHO classification system and demographic factors to gauge their prognosis. PMID- 29455199 TI - Clinical Features and Response to Treatment of Prolactinomas in Children and Adolescents: A Retrospective Single-Centre Analysis and Review of the Literature. AB - BACKGROUND: Paediatric prolactinomas are rare. The aim of this study was to investigate the clinical features and outcome of paediatric patients with prolactinomas. METHODS: In this single-centre retrospective analysis, clinical, biochemical, and radiological features of all paediatric patients with pituitary adenomas diagnosed between 2000 and 2016 were evaluated. RESULTS: Among 21 patients with pituitary adenomas, 12 patients with prolactinomas (median age 14.2 years, range 11-16.6 years, 8 females, 4 males) were identified (7 macro- and 5 microprolactinomas). The most common clinical symptoms were headaches (67%) and pubertal delay (67%). All patients with macroprolactinomas with prolactin concentrations >10,000 mU/L had at least 1 pituitary hormone deficiency. Cabergoline as first-line treatment (n = 11, median follow-up of 37 months, range 12-89 months) induced normoprolactinemia (n = 8), reduced the mean tumour volume by 80%, and ameliorated headaches (p = 0.016) and pubertal delay (p = 0.031), whereas intermittent moderate side effects occurred in 55%. CONCLUSION: Adolescents with headaches and pubertal delay should be investigated for prolactinomas. Treatment with cabergoline is well tolerated and effective in reducing clinical symptoms and prolactin concentrations was well as inducing tumour shrinkage. Further clinical prospective studies are needed to standardize paediatric treatment modalities. PMID- 29455200 TI - Cardiovascular and Patient Phenotype of Extended Haemodialysis: A Critical Analysis of Studying a Unique Patient Population. AB - BACKGROUND: Extended haemodialysis (EHD) has been associated with better outcomes compared to conventional (CHD) regimes. The cardiovascular (CV) profile of these patients has not been assessed in detail. METHODS: We report baseline demographic and CV phenotype of 36 CHD and 36 EHD participants to a longitudinal multicentre study. We measured pulse wave velocity (PWV), 24-h ambulatory blood pressure, sublingual dark-field capillaroscopy and vascular biomarkers. RESULTS: EHD patients were younger (p < 0.01), with less CV comorbidity (p = 0.04) and higher dialysis vintage (p < 0.01). Higher PWV in CHD (p = 0.02) was not independent of demographic differences in the 2 groups. Biomarker profiles were similar in EHD and CHD but abnormal compared to healthy controls. CONCLUSION: Although CV profiles in these 2 cohorts were similar, EHD patients were distinct from the CHD population in terms of age and dialysis vintage and appear to comprise a unique group. Direct comparison of outcomes in these groups is challenging due to clinical bias.

PMID- 29455202 TI - Phosphate and Calcium Control in Short Frequent Hemodialysis with the NxStage System One Cycler: Mass Balance Studies and Comparison with Standard Thrice Weekly Bicarbonate Dialysis. AB - BACKGROUND: Short frequent dialysis with NxStage System One cycler (NSO) has become increasingly popular as home hemodialysis prescription. Short dialysis sessions with NSO might not allow adequate phosphate (P) removal. METHODS: Single session and weekly balances of P and calcium (Ca) were compared in 14 patients treated with NSO (6 sessions/week) and in 14 patients on standard bicarbonate dialysis (BHD). RESULTS: NSO and BHD showed similar plasma P fall, with end dialysis plasma P slightly lower in BHD (2.2 +/- 0.5 vs. 2.7 +/- 0.8 mg/dL, p < 0.02). Single-session P removal was lower in NSO, but weekly removal was higher (3,488 +/- 1,181 mg vs. 2,634 +/- 878, p < 0.003). Plasma Ca increase was lower in NSO, with similar PTH fall. Ca balance varied according to start plasma Ca, dialysate to blood Ca gradient and net ultrafiltration. CONCLUSIONS: short, frequent home hemodialysis with NSO, on a 6/week-based prescription, allows higher weekly P removal than BHD. With the dialysate Ca concentration in use (6 mg/dL), total plasma Ca and iCa concentration increase is lower in NSO. PMID- 29455203 TI - Absence of Nicotinamide Nucleotide Transhydrogenase in C57BL/6J Mice Exacerbates Experimental Atherosclerosis. AB - BACKGROUND: Mitochondrial reactive oxygen species (ROS) contribute to inflammation and vascular remodeling during atherosclerotic plaque formation. C57BL/6N (6N) and C57BL/6J (6J) mice display distinct mitochondrial redox balance due to the absence of nicotinamide nucleotide transhydrogenase (NNT) in 6J mice. We hypothesize that differential NNT expression between these animals alters plaque development. METHODS: 6N and 6J mice were treated with AAV8-PCSK9 (adeno associated virus serotype 8/proprotein convertase subtilisin/kexin type 9) virus leading to hypercholesterolemia, increased low-density lipoprotein, and atherosclerosis in mice fed a high-fat diet (HFD). Mice were co-treated with the mitochondria-targeted superoxide dismutase mimetic MitoTEMPO to assess the contribution of mitochondrial ROS to atherosclerosis. RESULTS: Baseline and HFD induced vascular superoxide is increased in 6J compared to 6N mice. MitoTEMPO diminished superoxide in both groups demonstrating differential production of mitochondrial ROS among these strains. PCSK9 treatment and HFD led to similar increases in plasma lipids in both 6N and 6J mice. However, 6J animals displayed significantly higher levels of plaque formation. MitoTEMPO reduced plasma lipids but did not affect plaque formation in 6N mice. In contrast, MitoTEMPO surprisingly increased plaque formation in 6J mice. CONCLUSION: These data indicate that loss of NNT increases vascular ROS production and exacerbates atherosclerotic plaque development. PMID- 29455204 TI - Low Skeletal Muscle Density Is Associated with Early Death in Patients with Perihilar Cholangiocarcinoma Regardless of Subsequent Treatment. AB - BACKGROUND: Low skeletal muscle mass is associated with increased postoperative morbidity and worse survival following resection for perihilar cholangiocarcinoma (PHC). We investigated the predictive value of skeletal muscle mass and density for overall survival (OS) of all patients with suspected PHC, regardless of treatment. METHODS: Baseline characteristics and parameters regarding disease and treatment were collected from all patients with PHC from 2002 to 2014. Skeletal muscle mass and density were measured at the level of the third lumbar vertebra on CT. The association between skeletal muscle mass and density with OS was investigated using the Kaplan-Meier method and Cox survival. RESULTS: Median OS in 233 included patients did not differ between those with and without low skeletal muscle mass (p = 0.203), whereas a significantly different median OS (months) was observed between patients with low (HR 7.0, 95% CI 4.7-9.3) and high (HR 12.1, 95% CI 8.1-16.1) skeletal muscle density (p = 0.004). Low skeletal muscle density was independently associated with decreased OS (HR 1.78, 95% CI 1.03-3.07, p = 0.040) within the first 6 months but not after 6 months (HR 0.68, 95% CI 0.44-1.07, p = 0.093), after adjusting for age, tumour size and suspected peritoneal or other distant metastases on imaging. CONCLUSION: A time-dependent effect of skeletal muscle density on OS was found in patients with PHC, regardless of subsequent treatment. Low skeletal muscle density may identify patients at risk for early death. PMID- 29455205 TI - Use of Array Comparative Genomic Hybridization for the Diagnosis of DiGeorge Syndrome in Saudi Arabian Population. AB - DiGeorge syndrome (DGS) is a genetic disorder known as a clinically variable syndrome with over 180 associated phenotypic features. It is caused by a common human deletion in the 22q11.2 chromosomal region and currently is affecting approximately 1 in 4,000 individuals. Despite the prevalence of inherited diseases mainly due to consanguineous marriages, the current diagnosis of DGS in Saudi Arabia is mainly based on conventional high-resolution chromosome banding (karyotyping) and FISH techniques. However, advanced genome-wide studies for detecting microdeletions or duplications across the whole genome are needed. The aim of this study is to implement and use aCGH technology in clinical diagnosis of the 22q11.2 deletion in Saudi Arabian DGS patients and to confirm its effectiveness compared to conventional FISH and chromosome banding techniques. Thirty suspected DGS patients were assessed for chromosome 22q11.2 deletion using high-resolution G-banding, FISH, and aCGH. The aCGH results were compared with those obtained by the other 2 cytogenetic techniques. G-banding detected the 22q11.2 deletion in only 1 patient in the cohort. Moreover, it detected additional chromosomal aberrations in 3 other patients. Using FISH, allowed for detection of the 22q11.2 deletion in 2 out of 30 patients. Interestingly, the use of aCGH technique showed deletions in the chromosome 22q11.2 region in 8 patients, indicating a 4-fold increase in diagnostic detection capacity compared to FISH. Our results show the effectiveness of aCGH to overcome the limitations of FISH and G-banding in terms of diagnostic yield and allow whole genome screening and detection of a larger number of deletions and/or duplications in Saudi Arabian DGS patients. Except for balanced translocations and inversions, our data demonstrate the suitability of aCGH in the diagnostics of submicroscopic deletion syndromes such as DGS and most chromosomal aberrations or complex abnormalities scattered throughout the human genome. Our results recommend the implementation of aCGH in clinical genomic testing in Saudi Arabia to improve the diagnostic capabilities of health services while maintaining the use of conventional cytogenetic techniques for subsequent validation or for specific and known aberrations whenever required. PMID- 29455206 TI - A Potential Mechanism for Immune Suppression by Beta-Adrenergic Receptor Stimulation following Traumatic Injury. AB - BACKGROUND: beta-Adrenergic agents suppress inflammation and may play an important role in posttraumatic infections. Mechanisms may include inhibition of MAP kinase signaling. We sought to determine whether MKP-1 contributed to catecholamine suppression of innate immunity and also wanted to know whether early catecholamine treatment after traumatic injury increases the risk of later nosocomial infection. METHODS: We performed experiments using THP-1 cells and peripheral blood mononuclear cells from healthy individuals. We exposed cells to epinephrine and/or LPS and measured inflammatory gene transcription and MAP kinase activation. We inhibited MKP-1 activity to determine its role in catecholamine-induced immune suppression. Finally, we studied injured subjects to determine whether early catecholamine treatment was associated with nosocomial infection. RESULTS: Epinephrine increases MKP-1 transcripts and protein and decreases LPS-induced p38 and JNK phosphorylation and TNF-alpha gene transcription. RNAi inhibition of MKP-1 at least partially restores LPS-induced TNF-alpha gene expression (p = 0.024). In the clinical cohort, subjects treated with beta-adrenergic agents had an increased risk of ventilator-associated pneumonia (aOR = 1.9; 95% CI = 1.3-2.6) and bacteremia (aOR = 1.5; 95% CI = 1.1 2.3). CONCLUSIONS: MKP-1 may have a role in catecholamine-induced suppression of innate immunity, and exogenous catecholamines might contribute to nosocomial infection risk. PMID- 29455207 TI - Cognitive Function Declines Significantly during Haemodialysis in a Majority of Patients: A Call for Further Research. AB - INTRODUCTION: Cognitive impairment (CI) is very common condition that occurs in haemodialysis patients and it is associated with reduced functional capacity and mortality. We assessed the change in cognitive function during haemodialysis and associated risk factors. METHODS: All patients >=50 years, on haemodialysis for >=3 months, no dementia from 2 dialysis centres were selected. Cognition was assessed before and after a haemodialysis session using parallel versions of the Montreal Cognitive Assessment (MOCA) tool. Multiple regression was used to examine potential confounders. RESULTS: Eight-two patients completed both tests - median age 73 (52-91) years, 59% male, dialysis vintage 41 (3-88) months. Sixty two (76%) had CI at baseline. Cognition declined over dialysis (MOCA 21 +/- 4.8 to 19.1 +/- 4.1, p < 0.001) and domains affected were attention, language, abstraction and delayed recall. Age and dialysis vintage were independently associated with decline. CONCLUSION: Cognitive function declines over a haemodialysis session and this has significant clinical implications over health literacy, self-management and tasks like driving. More research is needed to find the cause for this decline in cognition. PMID- 29455208 TI - rhIGF-1 Treatment Increases Bone Mineral Density and Trabecular Bone Structure in Children with PAPP-A2 Deficiency. AB - AIM: Our objective was to determine changes in bone mineral density (BMD), trabecular bone score (TBS), and body composition after 2 years of therapy with recombinant human insulin-like growth factor-1 (rhIGF-1) in 2 prepubertal children with a complete lack of circulating PAPP-A2 due to a homozygous mutation in PAPP-A2 (p.D643fs25*) resulting in a premature stop codon. METHODS: Body composition, BMD, and bone structure were determined by dual-energy X-ray absorptiometry at baseline and after 1 and 2 years of rhIGF-1 treatment. RESULTS: Height increased from 132 to 145.5 cm (patient 1) and from 111.5 to 124.5 cm (patient 2). Bone mineral content increased from 933.40 to 1,057.97 and 1,152.77 g in patient 1, and from 696.12 to 773.26 and 911.51 g in patient 2, after 1 and 2 years, respectively. Whole-body BMD also increased after 2 years of rhIGF-1 from baseline 0.788 to 0.869 g/cm2 in patient 1 and from 0.763 to 0.829 g/cm2 in patient 2. After 2 years of treatment, both children had an improvement in TBS. During therapy, a slight increase in body fat mass was seen, with a concomitant increase in lean mass. No adverse effects were reported. CONCLUSION: Two years of rhIGF-1 improved growth, with a tendency to improve bone mass and bone microstructure and to modulate body composition. PMID- 29455209 TI - Obstructive Sleep Apnea and Otolaryngologic Manifestations in Children with Pseudohypoparathyroidism. AB - BACKGROUND/AIMS: Pseudohypoparathyroidism (PHP) is a rare, genetic disorder. Patients with PHP may have increased prevalence of obstructive sleep apnea (OSA) but this has not been prospectively studied. METHODS: We enrolled children aged 6 18 years with PHP and matched controls. Evaluation included physical examination, medical history, and polysomnography. RESULTS: Fifteen children with PHP type 1A (PHP1A) and 15 controls completed the study. Both groups were obese (BMI 32.2 +/- 8.7 vs. 31.7+/- 6.5). The majority of PHP1A patients required tympanostomy tubes (86.7%) and adenotonsillectomy (73.3%). The primary outcome, i.e., the obstructive disturbance index, was significantly higher in PHP1A children versus controls (1.8 +/- 2.3 vs. 0.6 +/- 0.5, p = 0.045). Children with PHP1A were more likely to have OSA compared with controls (60.0 vs. 13.3%, p = 0.008). Three siblings with PHP type 1B (PHP1B) were also studied (BMI 25.9 +/- 9.0). None had a history of adenotonsillectomy, one had tympanostomy tubes. The obstructive disturbance index (2.0 +/- 2.3) was similar to that of children with PHP1A. Two (66.7%) PHP1B participants had OSA. CONCLUSION: Children with PHP1A are at an increased risk for OSA compared with similarly obese peers. They also have higher rates of otitis media and adenotonsillar hypertrophy. Screening for OSA should be considered in all patients with PHP1A and possibly PHP1B though more research is needed. PMID- 29455210 TI - What We Do and Do Not Know about Women and Kidney Diseases; Questions Unanswered and Answers Unquestioned: Reflection on World Kidney Day and International Women's Day. AB - Chronic kidney disease affects approximately 10% of the world's adult population: it is within the top 20 causes of death worldwide, and its impact on patients and their families can be devastating. World Kidney Day and International Women's Day in 2018 coincide, thus offering an opportunity to reflect on the importance of women's health and specifically their kidney health, on the community and the next generations, as well as to strive to be more curious about the unique aspects of kidney disease in women so that we may apply those learnings more broadly. Girls and women, who make up approximately 50% of the world's population, are important contributors to society and their families. Gender differences continue to exist around the world in access to education, medical care, and participation in clinical studies. Pregnancy is a unique state for women, offering an opportunity for diagnosis of kidney disease, but also a state where acute and chronic kidney diseases may manifest, and which may impact future generations with respect to kidney health. There are various autoimmune and other conditions that are more likely to have an impact on women, with profound consequences for child bearing, and on the fetus. Women have different complications on dialysis than men, and are more likely to be donors than recipients of kidney transplants. In this editorial, we focus on what we do and do not know about women, kidney health, and kidney disease, and what we might learn in the future to improve outcomes worldwide. PMID- 29455211 TI - Intratympanic Injections of Dexamethasone in Delayed Endolymphatic Hydrops: A Prospective Clinical Study. AB - OBJECTIVE: This study was designed to evaluate the effectiveness of intratympanic dexamethazone (ITD) for the treatment of ipsilateral delayed endolymphatic hydrops (DEH). METHODS: Forty-one patients were diagnosed with ipsilateral DEH. Only 37 patients completed this study. Patients were randomly divided into 2 groups. Group A (n = 16) received oral medication, and group B (n = 21) received ITD once weekly for 4 consecutive weeks. RESULTS: In group A, 6 patients showed improvement in their vertigo. Four patients (25%) showed complete vertigo control, and 2 patients (12.5%) showed substantial vertigo control. In group B, 21 patients showed improvement in their vertigo, 11 patients (52%) showed complete vertigo control, and 10 patients (47%) showed substantial vertigo control. Only 1 case did not show any improvement in their vertigo. CONCLUSION: ITD is proven to be a valuable and promising alternative modality for the management of ipsilateral DEH. PMID- 29455212 TI - Fetal Risks and Maternal Renal Complications in Pregnancy with Preexisting Chronic Glomerulonephritis. AB - BACKGROUND Analysis the maternal and fetal risk predictors in pregnancy in conjunction with chronic glomerulonephritis (CGN) patients are helpful to understand the influence of kidney diseases on pregnancy and the effects of pregnancy on kidney diseases. The aim of this study was to determine the predictors of adverse maternal and fetal outcomes in CGN patients. MATERIAL AND METHODS Maternal and fetal outcomes in 64 pregnancies of CGN patients were retrospectively analyzed. We randomly selected 100 low-risk-pregnancy women without chronic kidney disease (CKD) at the same time as the control group. Clinical manifestations, laboratory data, medication, and outcomes during pregnancies of these patients were analyzed by univariate and logistic regression. RESULTS CGN patients were associated with higher adverse pregnancy outcomes versus general pregnancies. The gestational ages are shorter, and the incidence of preeclampsia, gestational hypertension, and abortion were increased. The rates of premature delivery, low birth weights, and intrauterine growth restriction were higher in the CGN group. Prenatal proteinuria and blood pressure were significantly increased compared with pre-pregnancy stage. Proteinuria (0.9+/-0.6 g/d vs. 0.5+/-0.3 g/d, P=0.032) and hypertension (6.9% vs. 3.4%, P=0.021) at 6 months after delivery were aggravated. Prenatal proteinuria >=3.5 g/d (OR 12.22, 95%CI 3.16~47.32, P=0.001) was the maternal risk predictor in pregnancy. Prenatal blood pressure >=160/110 mmHg (OR 8.97, 95%CI 1.69~47.53, P=0.010) and uric acid >=363 MUmol/L (OR 7.35, 95%CI 1.88~28.76, P=0.004) were the fetal risk predictors in pregnancy in conjunction with CGN patients. CONCLUSIONS Maternal-fetal risks are increased in pregnancies in conjunction with CGN patients. Prenatal proteinuria >=3.5 g/d, BP >=160/110 mmHg, and uric acid >=363 MUmol/L were the maternal and fetal risk predictors in pregnancy. PMID- 29455214 TI - An overview of complications affecting the Central Nervous System following bariatric surgery. AB - Bariatric surgery has been considered as an effective treatment for morbid obesity. Apart from procedures related complications, a broad spectrum of neurological disorders affecting any part of neuraxis has been reported following BS. Central nervous system complications, although less common than peripheral nervous system complications, carry significant morbidity and potential mortality. Encephalopathy, behavioral and psychiatric disorders, myelopathy and optic neuropathy are the most frequently reported CNS complications. Early detection and prompt management may improve or completely reverse these neurological complications. It is essential that the treating physicians must be aware of their clinical manifestations and management, so early diagnosis and treatment can prevent patients from suffering significant neurological deficits and even death. This review discusses the clinical manifestations of these complications in detail which will help concerned physician in earlier recognition and hence prevent the delay in specific treatment. PMID- 29455213 TI - Outcomes of Organ Transplantation from Donors with a Cancer History. AB - BACKGROUND The inherent challenges of selecting an acceptable donor for the increasing number and acuity of recipients has forced programs to take increased risks, including accepting donors with a cancer history (DWCH). Outcomes of organ transplantation using organs from DWCH must be clarified. We assessed transplant outcomes of recipients of organs from DWCH. MATERIAL AND METHODS Retrospective analysis of the Scientific Registry of Transplant Recipients data from January 1, 2000 to December 31, 2014 identified 8385 cases of transplants from DWCH. A Cox proportional hazard regression model and log-rank test were used to compare patient survival and hazard levels of various cancer types. RESULTS DWCH was an independent risk factor of 5-year patient survival (HR=1.089, 95% CI: 1.009 1.176, P=0.03) and graft survival (HR=1.129, 95% CI: 1.056-1.208, P<0.01) in liver and heart transplantation (patient survival: HR=1.112, 95% CI: 1.057-1.170, P<0.01; graft survival: HR=1.244, 95% CI: 1.052-1.472, P=0.01). There was no remarkable difference between the 2 groups in kidney and lung transplantation. Donors with genitourinary and gastrointestinal cancers were associated with inferior outcomes in kidney transplantation. Transplantation from donors with central nervous system cancer resulted in poorer survival in liver transplant recipients. Recipients of organs from donors with hematologic malignancy and otorhinolaryngologic cancer had poorer survival following heart transplantation. CONCLUSIONS Under the current donor selection criteria, recipients of organs from DWCH had inferior outcomes in liver and heart transplantation, whereas organs from DWCH were safely applied in kidney and lung transplantation. Specific cancer types should be cautiously evaluated before performing certain types of organ transplantation. PMID- 29455215 TI - Stroke and seizure continue to be the major brunt of in patient neurology care. An observation from teaching hospital. AB - OBJECTIVE: To assess the burden and describe the pattern of neurological disorders requiring admissions in a teaching hospital of Al Khobar. METHODS: This is a retrospective, cross sectional study, carried out in the Neurology Department of King Fahd Hospital of the University from January 2009 to December 2016. Neurological disorders were grouped as ischemic stroke, intracerebral hemorrhage, transient ischemic attack, cerebral venous sinus thrombosis, seizure disorders, central nervous system infection, multiple sclerosis, neuropathies, myopathies, headache, dementia and miscellaneous group. Data was entered and analyzed by Statistical Package for the Social Science (SPSS) version 22.0 (IBM Corp., Armonk, NY, USA). RESULTS: The records of 1,317 patients admitted under Neurology Service were analyzed. Out of that, 740 (56.2%) were male and 577 (43.8%) were female. Mean age was 46.9+?-24 years (mean+?-standard deviation). Ischemic stroke was the most common diagnosis (32%) followed by seizures (20%). Multiple sclerosis accounted for around 8% and central nervous system infections 5% of neurological admission. CONCLUSION: Ischemic stroke was found to be the most common etiology for hospitalization in our study. The results of our study are similar to previous literature. An urgent need to control major risk factors such as diabetes and hypertension is warranted to minimize the burden of stroke. PMID- 29455216 TI - Demographic and histopathological patterns of neuro-epithelial brain tumors in Eastern Province of Saudi Arabia. AB - OBJECTIVE: To review the demographic and pathological pattern of neuro-epithelial brain tumors in a tertiary referral center in the Eastern Province of Saudi Arabia and to compare the results of our study with other national and international studies. METHODS: This is a retrospective chart-review study of all patients with neuro-epithelial brain tumors referred and treated in our center between January 2010 and January 2015. The age, gender, tumor location, and histopathology were recorded. RESULTS: The total number of cases was 149 including 96 adult cases and 53 pediatric cases. 58% of cases were male, and 42% were female. The age group distribution showed 2 peaks; one in the first 5 years of life and the second was in the age range from 26-45 years old. Glioblastoma multiforme was the most common pathological type (32%), followed by medulloblastoma (13.3%). This study showed similar results to a previous study conducted in the Eastern Province in terms of age and gender distribution, but pathologically, the tumors diagnosed in our study were generally of a higher grading. When comparing our results to other international studies in nearby countries (Jordan and Egypt), we found similarities in pathological patterns and age distribution. However, when comparing our results to a western country (USA), we found considerable differences in the age group distribution. CONCLUSION: Neuro-epithelial brain tumors in Saudi Arabia affect younger population according to our study compared to Western countries. These findings are similar to other studies from Middle Eastern countries. In addition, our study showed a significant increase in high grade gliomas in the Eastern Province compared to an old historical study. This increase should be interpreted cautiously due to possible selection errors, changes in pathological grading, and expertise. PMID- 29455217 TI - Comparison of 2 methods of neuropathic pain assessment in carpal tunnel syndrome and hand functions. AB - OBJECTIVE: To compare the effectiveness of the Leeds Assessment of Neuropathic Symptoms and Signs Scale (LANSS) to the painDETECT questionnaire (PD-Q) in Carpal Tunnel Syndrome (CTS), and determine if there are any differences between hand related functions in the 2 questionnaires. METHODS: This prospective clinical trial was conducted from April to July 2014. Ninety patients with a positive Tinel or Phalen sign were recruited. Hands were evaluated by electromyography and grouped according to mild, moderate or severe involvement. Neuropathic pain was analysed by the LANSS and the PD-Q; hand functions were evaluated by the Duruoz Hand Index (DHI), Semmes Weinstein monofilaments and grip strength. RESULTS: Electromyographic findings revealed 32.9% of hands had mild, 61.8% had moderate and 5.3% had severe CTS. There was a correlation between the LANSS scores and the Visual Analogue Scale (VAS) pain, while the PD-Q scores were correlated with the VAS pain, DHI and Semmes Weinstein Monofilaments (SWM). Comparison of the hand related parameters of the questionnaires showed there was a statistically significant difference between the 2 groups with respect to the DHI and SWM tests in the PD-Q. However, there was no difference in the LANSS. CONCLUSION: Although there was a significant correlation between the LANSS and PD-Q scores, the PD-Q scores revealed better correlation coefficients in VAS pain, DHI scores and SWM tests. In conclusion, the PD-Q seems to be better than the LANSS both in neuropathic pain and in detecting functions related to hand abilities. PMID- 29455218 TI - APOE Gene polymorphism among Jordanian Alzheimer's patients with relation to lipid profile. AB - OBJECTIVE: To investigate the frequencies of the apolipoprotein E (APOE) alleles and genotypes and study their relationship with the lipid profile in Jordanian patients with late-onset Alzheimer's disease (AD). METHODS: This case-control study was carried out on 71 Jordanian individuals: 38 patients with late-onset AD (age >/=65 years) and 33 age-matched healthy controls. All participants were recruited from senior homes and Jordan University Hospital, Amman, Jordan between January 2010 and December 2013. Each sample was examined for APOE's 3 major isoforms (e2, e3, e4) using the polymerase chain reaction technique (PCR) followed by the sequencing technique. In addition, samples were screened for lipid profiles (total cholesterol (TC), high-density lipoprotein (HDL), lower density lipoprotein (LDL), and triglyceride (TG) levels. RESULTS: The e3/e4 genotype and e4 allele prevalence were higher in AD patients compared to healthy controls (26.3% vs. 3.0%, p=0.03 and 15.8% vs. 4.5%, p=0.03; respectively). In the AD group, the e2 carriers showed the lowest levels of total and LDL cholesterol, and the e4 carriers showed the highest levels of total and LDL cholesterol, although the difference was not statistically significant (p>0.05). CONCLUSION: APOE-e4 frequency was almost 4 times higher in the AD group compared to the control group, and this difference was statistically significant. A trend that was observed in the AD group regarding the lipid profile and e2 and e4 carriers requires further investigation using a larger sample size. PMID- 29455219 TI - Endoscopic transsphenoidal approach to skull base lesions. A clinical prospective study. AB - OBJECTIVE: To review the patients operated by endoscopic transphenoidal approach for skull base lesions. All the clinical data including age, gender, type of pathology, surgical outcome and surgical complications were studied. METHODS: A clinical prospective study was conducted on 94 cases with skull base lesion that were treated in Neuroscience Hospital in Baghdad, Iraq between October 2011 and December 2016. We followed each patient for an average of 2 years after surgery to determine most common lesion involving the skull base, age and gender distribution, surgical outcome, complications and hospital accommodation. Freeze system of Storz all the cases in the study. RESULTS: The majority of our patients were between the ages of 20-29 years. Among the 94 patients, 67% had macro adenomas, followed by craniopharyngioma 11%. The mortality rate was 2.1%, Gross total removal was 57.4%. All patients show improvement of the headache after surgery, visual improvement was noticed in 73.4% and hospital accommodation was 2 5 days. Three patients developed cerebrospinal fluid leak, Infection meningitis developed in 3 patients 3.1%, and 2 patients (2.1%) suffered from hormonal disorders and were referred to endocrinologist for therapy. Diabetes insipidus developed as a temporary complication in 4 cases (4.2%). CONCLUSION: Trassphenoidal surgery is relatively safe surgery for properly selected patients. PMID- 29455220 TI - How do physical capacity, fatigue and performance differ in children with duchenne muscular dystrophy compared with their healthy peers? AB - OBJECTIVE: To compare the fatigue levels and energy expenditure of children with Duchenne Muscular Dystrophy (DMD) at different functional levels with healthy children. METHODS: The cross-sectional study was carried out in the Unit of Pediatric Neuromuscular Diseases in the Department of Physiotherapy and Rehabilitation, Faculty of Health Science, Hacettepe University between March 2015 and January 2016. Fifty two children diagnosed with DMD in Level I-III according to the Brooke Functional Classification Scale and 17 healthy children were included in the study. The Six Minute Walk Test (6MWT), Northstar Ambulatory Assessment Scale (NSAA), Physiological Cost Index (PCI), and Timed performance tests were used to assess the children. RESULTS: Comparison in terms of PCI indicated a difference between Levels 2 and 3, and Levels 1 and 3 (p<0.0083). A difference was found in ascending and descending 4 stairs after 6MWT when fatigue after activity was evaluated. CONCLUSION: The walking distances, fatigue levels and energy expenditure of DMD patients were higher than the healthy peers. This difference was more prominent with decreasing functional level. PMID- 29455221 TI - Perioperative lumbar drain utilization in transsphenoidal pituitary resection. AB - OBJECTIVE: To evaluate lumbar drain (LD) efficacy in transnasal resection of pituitary macroadenomas in preventing postoperative cerebrospinal fluid (CSF) leak, technique safety, and effect on length of hospital stay. METHODS: We conducted a retrospective data review of pituitary tumor patients in our institution who underwent surgery between December 2006 and January 2013. All patients were operated on for complete surgical resection of pituitary macroadenoma tumors. Patients were divided into 2 groups: group 1 received a preoperative drain, while LD was not preoperatively inserted in group 2. In cases of tumors with suprasellar extension with anticipation of high-flow leak, LD was inserted after the patient was intubated and in a lateral position. Lumbar drain was used for 48 hours, and the drain was removed if no leak was observed postoperatively. In documented postoperative CSF leak patients with no preoperative drain, the leak was treated by LD trial prior to surgical reconstruction. Cases in which leak occurred 6 months postoperatively were excluded. RESULTS: Our study population consisted of 186 patients, 99 women (53%) and 87 men (47%), with a mean age of 50.3+/-16.1 years. Complications occurred in 7 patients (13.7%) in group 1 versus 21 (15.5%) in group 2 (p=0.72). Postoperative CSF leak was observed in 1 patient (1.9%) in group 1 and 7 (5%) in group 2 (Fisher exact test=0.3). Length of hospital stay was a mean of 4.7+/-1.9 days in group 1 and a mean of 2.7+/-2.4 days in group 2 (p<001). The most common reason to extend hospital stay was management of diabetes insipidus. CONCLUSION: Although LD insertion is generally considered safe with a low risk of complications, it increases the length of hospitalization. Minor complications include headaches and patient discomfort. PMID- 29455222 TI - Encephalopathy mimicking non-convulsive status Epilepticus. AB - Primary hyperammonemic encephalopathy due to urea cycle disorders (UCD) typically manifests with episodic unresponsiveness and this clinical entity is not often included in the differential diagnosis of presumed non-convulsive status epilepticus (NCSE). However, this diagnostic consideration has therapeutic implications. In this report, we document the therapeutic importance of elucidating the specific cause of hyperammonemic encephalopathy that closely mimicked NCSE through 2 unique illustrative cases. PMID- 29455223 TI - Sialidosis type I presenting with a novel mutation and advanced neuroimaging features. AB - Sialidosis is a rare lysosomal storage disease caused by neuraminidase gene (NEU1) mutation and a deficiency of the enzyme neuraminidase. The aim of this study was to examine the sialidosis type 1 brain using volumetric magnetic resonance imaging (MRI), diffusion tensor imaging and functional MRI in comparison to 3 controls. The patients gene analysis identified compound heterozygous mutation in the NEU1 that is shown to be associated with the sialidosis type 1. In this very rarely seen case, we found volume changes in different brain structures. We found that subthalamic nucleus volumes were found to be smaller in the patient compared to the controls. Also, sialidosis type 1 had significantly smaller cerebellar volume compared with the control group. The case had higher mean diffusivity and lower fractional anisotropy values in the cerebellum and displayed abnormal functional connectivity. PMID- 29455225 TI - Editorial Message.

AB - OBJECTIVE: To explore therapeutic attitude of healthcare providers practicing in pediatric critical care in Saudi Arabia toward patients with Spinal Muscular Atroph (SMA) Type I, and to explore their awareness about the International Consensus statement for SMA care. METHODS: A cross-sectional survey was conducted in April 2015 during 6th Saudi Critical Care Conference, targeting physicians and respiratory therapists practicing in Pediatric Critical Care. RESULTS: Sixty participants accepted to participate in this survey. Out of those who answered the questionnaire, 44 were included in the analysis. Majority (66%) of participants were unaware of the International Consensus guidelines for SMA. Endotracheal intubation was reported as an acceptable intervention in SMA patients with acute respiratory failure by 43% of participants. Similarly, chronic home ventilation was agreed by 41% of participants. CONCLUSION: A nationwide adaptation of the International SMA Consensus guidelines for children with SMA I is recommended, aiming to decrease variability and standardize their management across various healthcare facilities in Saudi Arabia. PMID- 29455227 TI - The clinical features of patients concurrent with Guillain-Barre syndrome and myasthenia gravis. AB - OBJECTIVE: To evaluate all the coincidence cases of Guillain-Barre syndrome (GBS) and myasthenia gravis (MG). METHODS: We performed web-based research of the overlapping incidence of GBS and MG in studies occurring from 1982 to 2016 and restricted to the English language. RESULTS: Among 15 cases, an elevated CSF protein level without pleocytosis was found in 10 cases (66.7%); reduced nerve conduction was found in 13 cases (86.6%); a positive repetitive nerve stimulation test occurred in 11 cases (73.3%); anti-AChR antibodies were found in 13 cases (86.6%); anti-GQ1b antibodies were found in 6 cases (40%); a positive edrophonium chloride test was present in 10 cases (66.7%); and a co-occurring thymoma or thymectomy occurred in 4 cases (26.6%). The MG co-occurred with acute inflammatory demyelinating polyneuropathy (AIDP) in 8 cases and with Miller Fisher Syndrome in 5 cases. Treatment in the assessed cases included pyridostigmine (10 cases), prednisolone (7 cases), intravenous immunoglobulin (9 cases), plasmapheresis (3 cases), combined intravenous immunoglobulin and plasmapheresis in one case, and immunosuppressive drugs in 2 cases (azathioprine). Functional outcome was mentioned in 13 patients. The prognosis was favorable in 8 of the 15 recorded patients (Hughes 0-1), and 2 cases resulted in death. CONCLUSION: Although comorbidity of GBS and MG is extremely rare, early recognition of this combination of inflammation of peripheral nerves and the neuromuscular junction is of great importance for both initial treatment and a better prognosis.

PMID- 29455229 TI - Effect of Hospital Readmission Reduction on Patients at Low, Medium, and High Risk of Readmission in the Medicare Population. AB - BACKGROUND: Hospitalization and readmission rates have decreased in recent years, with the possible consequence that hospitals are increasingly filled with high risk patients. OBJECTIVE: We studied whether readmission reduction has affected the risk profile of hospitalized patients and whether readmission reduction was similarly realized among hospitalizations with low, medium, and high risk of readmissions. DESIGN: Retrospective study of hospitalizations between January 2009 and June 2015. PATIENTS: Hospitalized fee-for-service Medicare beneficiaries, categorized into 1 of 5 specialty cohorts used for the publicly reported hospital-wide readmission measure. MEASUREMENTS: Each hospitalization was assigned a predicted risk of 30-day, unplanned readmission using a risk adjusted model similar to publicly reported measures. Trends in monthly mean predicted risk for each cohort and trends in monthly observed to expected readmission for hospitalizations in the lowest 20%, middle 60%, and highest 20% of risk of readmission were assessed using time series models. RESULTS: Of 47,288,961 hospitalizations, 16.2% (n = 7,642,161) were followed by an unplanned readmission within 30 days. We found that predicted risk of readmission increased by 0.24% (P = .03) and 0.13% (P = .004) per year for hospitalizations in the surgery/ gynecology and neurology cohorts, respectively. We found no significant increase in predicted risk for hospitalizations in the medicine (0.12%, P = .12), cardiovascular (0.32%, P = .07), or cardiorespiratory (0.03%, P = .55) cohorts. In each cohort, observed to expected readmission rates steadily declined, and at similar rates for patients at low, medium, and high risk of readmission. CONCLUSIONS: Hospitals have been effective at reducing readmissions across a range of patient risk strata and clinical conditions. The risk of readmission for hospitalized patients has increased for 2 of 5 clinical cohorts. PMID- 29455231 TI - Impact of a Multicenter, Mentored Quality Collaborative on Hospital-Associated Venous Thromboembolism. AB - BACKGROUND: Reliable prophylaxis of hospitalassociated venous thromboembolism (HA VTE) is not achieved in many hospitals. Efforts to improve prophylaxis have had uneven results. OBJECTIVE: To reduce HA-VTE with a scalable quality improvement collaborative. DESIGN: A prospective, unblinded, open-intervention study with historical controls. PARTICIPANTS AND SETTING: All adult inpatients at 35 community hospitals in California, Arizona, and Nevada. INTERVENTIONS: A centrally supported collaborative implementing standardized VTE risk assessment and prophylaxis. Protocols were developed with 9 "pilot" sites, which received individualized mentoring. Finished protocols were disseminated to 26 "spread" sites, which received improvement webinars without mentoring. Active surveillance for real-time correction of suboptimal prophylaxis was funded in pilot sites and encouraged in spread sites. Planning and minimal improvement work began in 2011; most implementation occurred in 2012 and 2013. MEASUREMENTS: Rates of per protocol prophylaxis (at pilot sites), and compliance with The Joint Commission VTE measures (all sites), were monitored starting in January 2012. The International Classification of Diseases, 9th Edition-Clinical Modification codes were used to determine the rates of HA-VTE within 30 days of discharge, heparininduced thrombocytopenia, and anticoagulation adverse events; preimplementation (2011) rates were compared with postimplementation (2014) rates. RESULTS: Protocol-appropriate prophylaxis rates and The Joint Commission measure compliance both reached 97% in 2014, up from 70% to 89% in 2012 and 2013. Five thousand three hundred and seventy HA-VTEs occurred during 1.16 million admissions. Four hundred twenty-eight fewer HA-VTEs occurred in 2014 than in 2011 (relative risk 0.78; 95% confidence interval, 0.73-0.85). HA-VTEs fell more in pilot sites than spread sites (26% vs 20%). The rates of adverse events were reduced or unchanged. CONCLUSIONS: Collaborative efforts were associated with improved prophylaxis rates and fewer HA-VTEs. PMID- 29455228 TI - Numeracy, Health Literacy, Cognition, and 30-Day Readmissions among Patients with Heart Failure. AB - BACKGROUND: Numeracy, health literacy, and cognition are important for chronic disease management. Prior studies have found them to be associated with poorer selfcare and worse clinical outcomes, but limited data exists in the context of heart failure (HF), a condition that requires patients to monitor their weight, fluid intake, and dietary salt, especially in the posthospitalization period. OBJECTIVE: To examine the relationship between numeracy, health literacy, and cognition with 30-day readmissions among patients hospitalized for acute decompensated HF (ADHF). DESIGN, SETTING, PATIENTS: The Vanderbilt Inpatient Cohort Study is a prospective longitudinal study of adults hospitalized with acute coronary syndromes and/or ADHF. We studied 883 adults hospitalized with ADHF. MEASUREMENTS: During their hospitalization, a baseline interview was performed in which demographic characteristics, numeracy, health literacy, and cognition were assessed. Through chart review, clinical characteristics were determined. The outcome of interest was 30-day readmission to any acute care hospital. To examine the association between numeracy, health literacy, cognition, and 30-day readmissions, multivariable Poisson (log-linear) regression was used. RESULTS: Of the 883 patients admitted for ADHF, 23.8% (n = 210) were readmitted within 30 days; 33.9% of the study population had inadequate numeracy skills, 24.6% had inadequate/marginal literacy skills, and 53% had any cognitive impairment. Numeracy and cognition were not associated with 30-day readmissions. Though (objective) health literacy was associated with 30-day readmissions in unadjusted analyses, it was not in adjusted analyses. CONCLUSIONS: Numeracy, health literacy, and cognition were not associated with 30-day readmission among this sample of patients hospitalized with ADHF. PMID- 29455232 TI - Startle reflex modulation by affective face "Emoji" pictographs. AB - The current research was designed to assess possible differences in the emotional content of pleasant and unpleasant face emoji using acoustically evoked eyeblink startle reflex response. Stimuli were selected from Emojipedia Webpage. First, we assessed these stimuli with a previous independent sample of 190 undergraduate students (46 males and 144 females) mean age of 21.43 years (SD 3.89). A principal axis method was performed using the 30 selected emoji faces, extracting two factors (15 pleasant and 15 unpleasant emoji). Second, we measured the acoustic startle reflex modulation in 53 young adult women [mean age 22.13 years (SD 4.3)] during the viewing of each of the 30 emoji emotional faces in the context of the theory of motivation and emotion proposed by Lang (1995), but considering only the valence dimension. We expected to find higher acoustically evoked startle responses when viewing unpleasant emoji and lower responses for pleasant ones, similarly to the results obtained in the studies using human faces as emotional stimulus. An ANOVA was conducted to compare acoustic startle responses associated with pleasant and unpleasant emoji. Results yielded main effects for picture valence (lambda = 0.80, F(1, 50) = 12.80, p = .001, eta2 = 0.20). Post-hoc t test analysis indicated significant differences in the startle response between unpleasant (50.95 +/- 1.75) and pleasant (49.14 +/- 2.49) emoji (t (52) = 3.59, p = .001), with a Cohen's d = 0.495. Viewing affective facial emoji expressions modulates the acoustic startle reflex response according to their emotional content.

PMID- 29455234 TI - Blastic plasmacytoid dendritic cell neoplasm: update on therapy especially novel agents. AB - Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and aggressive hematopoietic malignancy mainly affecting elderly patients. Most patients present with asymptomatic skin lesions as the first symptom and has a high frequency of bone marrow involvement. BPDCN is typically characterized by CD4+ and CD 56+ co expression without common lymphoid or myeloid lineage markers. There is no consensus on the optimal therapeutic strategy for BPDCN. It is highly responsive to chemotherapy but the median event-free survival is very short. Allogeneic stem cell transplantation may improve the prognosis of BPDCN but the rate of relapse is still high. There are no specific targeted agents approved for patients with BPDCN, but advances in the understanding of the pathobiology of BPDCN and the results of early clinical studies have revealed novel targets and potentially effective agents. Novel targeted therapies may improve outcomes for patients with BPDCN in the future. PMID- 29455235 TI - Enlarged spleen is associated with low neutrophil and platelet engraftment rates and poor survival after allogeneic stem cell transplantation in patients with acute myeloid leukemia and myelodysplastic syndrome. AB - Primary graft failure can be a cause of early morbidity and mortality after allogeneic hematopoietic stem cell transplantation (HSCT), as it leads to a high risk of severe infections and bleeding. Splenomegaly is associated with primary graft failure in patients of myelofibrosis, but the association between splenomegaly and outcomes after HSCT in patients with myeloid malignancies has not been previously evaluated. The aim of this study was to investigate the effect of spleen volume on engraftment kinetics in patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). We enrolled 85 patients. The median spleen volume was 146 cm3 (quartile 88-201 cm3). The adjusted hazard ratios for neutrophil and platelet engraftments were 0.17 (0.07-0.40, p < 0.001) and 0.19 (0.05-0.69, p = 0.011), respectively, for the high-risk group, at a cutoff splenic volume of 320 cm3. Overall survival at 3 years after HSCT was significantly poor in the high-risk group with an adjusted hazard ratio of 13.8 (2.61-72.4, p = 0.002). Enlarged spleen was associated with low neutrophil and platelet engraftment rates and poor survival after allogeneic HSCT in patients of AML and MDS.

PMID- 29455237 TI - Randomized controlled trial of 2% lidocaine gel versus water-based lubricant for multi-channel urodynamics. AB - INTRODUCTION AND HYPOTHESIS: The purpose of the study was to determine if there is a difference in pain during and after multichannel urodynamic testing in women when using 2% lidocaine gel versus water-based lubricant. METHODS: This was a randomized, controlled, double-blinded study. Women scheduled to undergo urodynamic testing were invited to participate. Participants were randomized to lidocaine 2% gel or water-based lubricant for use during testing. Both participant and examiner were blinded to the type of gel. Pain was assessed by the Wong-Baker pain scale from 0 to 10 at four points during the examination. After testing, participants completed a questionnaire to assess their expectations of pain and embarrassment with urodynamic testing. The examiner also completed a questionnaire to assess his/her impression of the participant's pain during the procedure. RESULTS: The women in the lidocaine group had lower pain scores after the cotton tipped swab test (1.3 vs 3.6, lidocaine vs lubricant respectively, p < 0.001) and after placement of urodynamic catheters (1.4 vs 3.9, lidocaine vs lubricant, respectively, p < 0.001). Mean pain scores 30 min post completion of the study were similar between groups (0.7 vs 1.2, 1.4 vs 3.9, lidocaine vs lubricant respectively, p = 0.19). Participants reported that pain during the study was better than expected in both groups. Physician perception of the participant's pain during testing was lower in the lidocaine group (2 vs 3, lidocaine vs lubricant respectively p = 0.008). CONCLUSION: Use of 2% lidocaine gel during in and out catheterization, cotton-tipped swab test, and urodynamic testing decreases pain during these procedures. PMID- 29455238 TI - A blinded observational cohort study of the microbiological ecology associated with pyuria and overactive bladder symptoms. AB - INTRODUCTION AND HYPOTHESIS: This study sought to characterise the microbial ecology of the lower urinary tract in patients with symptoms of overactive bladder (OAB) using culture of the urinary urothelial cell sediment. The pathological significance of the microbiome was assessed through its relationship with known urothelial inflammatory markers and patient reported symptoms. METHODS: Adult female patients with OAB symptoms and asymptomatic controls were assessed at 12 study visits scheduled every 4 weeks. At each visit, all participants provided a clean-catch midstream urine (MSU) that was analysed to count white and uroepithelial cells, submitted to standard culture and spun urothelial-cell-sediment culture. Symptoms were assessed using validated questionnaires. RESULTS: This analysis shows that OAB patients differ consistently from controls, demonstrating differences in bacterial ecology (t 4.57, p 0.0001), in the microscopic pyuria count (t -6.37, p 0.0001) and presence of infected urothelial cells (t -4.21, p 0.0001). The primary outcome measure of bacterial growth [colony-forming units (CFU) ml-1] was higher in OAB patients than in controls throughout the 12 months. Data showed a correlation between symptoms and pyuria, with notable urgency correlating with pyuria and epithelial cell shedding. The routine urine cultures (with a threshold of reporting a positive result as 105 CFU/ml) were unable to distinguish OAB patients from controls. However, sediment cultures differed significantly, and there was a correlated increased immune response amongst OAB patients. CONCLUSIONS: This study supports the need to re-examine the OAB phenotype given this association with microbial colonisation.

AB - Candidatus Syngnamydia salmonis (Chlamydiales, Simkaniaceae) was described as an epitheliocystis-causing bacterium from the gills of Atlantic salmon (Salmo salar) in Norway. A bacterium showing 99.2% 16S rRNA identity to Cand. S. salmonis is able to multiply in Paramoeba perurans and based on the classification criteria this bacterium could represent the same species as Cand. S. salmonis. Sequencing the genome of the cultured bacterium has made it possible to fulfill the minimal standards for genetic characterization of species within the order Chlamydiales. The complete rRNA genes, the amino acid sequences of SucA, PepF, Adk, HemL, DnaA, FtsK and FabI, are presented in addition to the morphology of the Chlamydia-like morphs in the cytoplasm of P. perurans. PMID- 29455240 TI - Taxonomic structure and function of seed-inhabiting bacterial microbiota from common reed (Phragmites australis) and narrowleaf cattail (Typha angustifolia L.). AB - The present study investigated the endophytic bacterial communities in the seeds of mature, natural common reed (Phragmites australis) and narrowleaf cattail (Typha angustifolia L.). Additionally, seed endophytic bacterial communities were compared with rhizospheric and root endophytic bacterial communities using Illumina-based sequencing. Seed endophytic bacterial communities were dominated by Proteobacteria (reed, 41.24%; cattail, 45.51%), followed by Bacteroidetes (reed, 12.01%; cattail, 10.41%), Planctomycetes (reed, 10.36%; cattail, 9.09%), Chloroflexi (reed, 8.72%; cattail, 6.45%), Thermotogae (reed, 5.43%; cattail, 6.11%), Tenericutes (reed, 3.63%; cattail, 3.97%) and Spirochaetes (reed, 3.32%; cattail, 3.90%). The dominant genera were Desulfobacter (reed, 8.02%; cattail, 8.96%), Geobacter (reed, 2.74%; cattail, 2.81%), Thiobacillus (reed, 2.71%; cattail, 2.41%), Sulfurimonas (reed, 2.47%; cattail, 2.31%), Methyloversatilis (reed, 2.29%; cattail, 2.05%) and Dechloromonas (reed, 1.13%; cattail, 1.48%). Obvious distinctions were observed among the respective rhizospheric, root endophytic and seed endophytic bacterial communities. Principal coordinate analysis with weighted UniFrac distance and the heat map analysis demonstrated that the seed endophytic bacterial communities were distinct assemblages rather than a subgroup of rhizobacterial communities or root endophytic bacterial communities. These results provide new information regarding endophytic bacteria associated with seeds of wetland plants and demonstrate a variety of genera that have a strong potential to enhance phytoremediation in the wetland ecosystem. PMID- 29455241 TI - COX-2-derived PGE2 triggers hyperplastic renin expression and hyperreninemia in aldosterone synthase-deficient mice. AB - Pharmacological inhibition or genetic loss of function defects of the renin angiotensin aldosterone system (RAAS) causes compensatory renin cell hyperplasia and hyperreninemia. The triggers for the compensatory stimulation of renin synthesis and secretion in this situation may be multimodal. Since cyclooxygenase 2 (COX-2) expression in the macula densa is frequently increased in states of a defective RAAS, we have investigated a potential role of COX-2 and its derived prostaglandins for renin expression and secretion in aldosterone synthase deficient mice (AS-/-) as a model for a genetic defect of the RAAS. In comparison with wild-type mice (WT), AS-/- mice had 9-fold and 30-fold increases of renin mRNA and of plasma renin concentrations (PRC), respectively. Renin immunoreactivity in the kidney cortex of AS-/- mice was 10-fold higher than in WT. Macula densa COX-2 expression was 5-fold increased in AS-/- kidneys relative to WT kidneys. Treatment of AS-/- mice with the COX-2 inhibitor SC-236 for 1 week lowered both renal renin mRNA and PRC by 70%. Hyperplastic renin cells in AS-/- kidneys were found to express the prostaglandin E2 receptors EP2 and EP4. Global deletion of EP2 receptors did not alter renin mRNA nor PRC values in AS-/- mice. Renin cell-specific inducible deletion of the EP4 receptor lowered renin mRNA and PRC by 25% in AS-/- mice. Renin cell-specific inducible deletion of the EP4 receptor in combination with global deletion of the EP2 receptor lowered renin mRNA and PRC by 70-75% in AS-/- mice. Lineage tracing of renin-expressing cells revealed that deletion of EP2 and EP4 leads to a preferential downregulation of perivascular renin expression. Our findings suggest that increased macula densa COX-2 activity in AS-/- mice triggers perivascular renin expression and secretion via prostaglandin E2. PMID- 29455242 TI - Heightened CXCR4 and CXCL12 expression in NF1-associated neurofibromas. AB - BACKGROUND: Neurofibromatosis type 1 (NF1) is a common autosomal dominantly inherited disorder that affects both the skin and the nervous system. NF1 occurs due to the mutations in the NF1 gene. Neurofibromas are the most common Schwann cell-based tumors in NF1 patients, which are mainly categorized into dermal and plexiform neurofibromas. Studies on different tumor types demonstrate that CXCR4 expression increases in tumor tissues and is linked to metastasis and cancer progression. PURPOSE: In the present study, we aimed to analyze the gene expression of CXCR4, and its ligand CXCL12, in human neurofibromas. METHODS: Eight NF1 patients aged between 5 and 37 (2 males, 6 females) were selected. The patient group comprised 1 plexiform neurofibroma, 1 pheochromocytoma, and 6 dermal neurofibromas. Following pathological examination and diagnosis, tumors were co-stained with antibodies against Schwann cell marker S100 and target molecule CXCR4. CXCR4 expression in Schwann cell-based tumors was detected at the protein level. RNA isolated from the same tumors was used for RT-PCR-based studies to measure the quantitative expression of CXCR4 and CXCL12. RESULTS: CXCR4 gene expression increased 3- to 120-fold and CXCL12 gene expression increased 33- to 512-fold in all human Schwann cell-based tumors. CONCLUSION: In order to validate the role of CXCR4 and its relationship with CXCL12 in NF1, future studies should be performed with additional tumors and different tumor types. PMID- 29455244 TI - Rotation of intramedullary alignment rods affects distal femoral cutting plane in total knee arthroplasty. AB - PURPOSE: Intramedullary rods are widely used to align the distal femoral cut in total knee arthroplasty. We hypothesised that both coronal (varus/valgus) and sagittal (extension/flexion) cutting plane are affected by rotational changes of intramedullary femoral alignment guides. METHODS: Distal femoral cuts using intramedullary alignment rods were simulated by means of a computer-aided engineering software in 4 degrees , 6 degrees , 8 degrees , 10 degrees , and 12 degrees of valgus in relation to the femoral anatomical axis and 4 degrees extension, neutral, as well as 4 degrees , 8 degrees , and 12 degrees of flexion in relation to the femoral mechanical axis. This reflects the different angles between anatomical and mechanical axis in coronal and sagittal planes. To assess the influence of rotation of the alignment guide on the effective distal femoral cutting plane, all combinations were simulated with the rod gradually aligned from 40 degrees of external to 40 degrees of internal rotation. RESULTS: Rotational changes of the distal femoral alignment guides affect both the coronal and sagittal cutting planes. When alignment rods are intruded neutrally with regards to sagittal alignment, external rotation causes flexion, while internal rotation causes extension of the sagittal cutting plane. Simultaneously the coronal effect (valgus) decreases resulting in an increased varus of the cutting plane. However, when alignment rods are intruded in extension or flexion partly contradictory effects are observed. Generally the effect increases with the degree of valgus preset, rotation and flexion. CONCLUSION: As incorrect rotation of intramedullary alignment guides for distal femoral cuts causes significant cutting errors, exact rotational alignment is crucial. Coronal cutting errors in the distal femoral plane might result in overall leg malalignment, asymmetric extension gaps and subsequent sagittal cutting errors. PMID- 29455245 TI - Chronic hyperinsulinemia induced miR-27b is linked to adipocyte insulin resistance by targeting insulin receptor. AB - Defect in insulin signaling leads to the development of insulin resistance followed by type 2 diabetes. Exploiting our previously developed physiological chronic hyperinsulinemia (CI)-mediated insulin resistance (IR) model, we wanted to understand how miRNAs contribute to the development of IR. Amongst the identified and validate miRNAs, the expression of miR-27b was found to be highly upregulated during CI-induced IR in 3T3-L1 adipocytes. We also validated the expression of miR-27b in CI-induced IR in human mesenchymal stem cell (hMSC) derived adipocytes and in vivo high fat diet (HFD)-induced IR mice model. Bioinformatics target prediction softwares and luciferase reporter assay identified insulin receptor (INSR) as one of a prime target of miR-27b. Lentiviral mediated overexpression of miR-27b impairs insulin signaling by modulating INSR expression that in turn led to decreased glucose uptake in both 3T3-L1 and hMSC-derived adipocytes. Conversely, inhibition of miR-27b reversed CI mediated suppression of target protein INSR and improved phosphorylation of Akt, a nodal protein of insulin signaling that is impaired by CI treatment. Lentiviral mediated overexpression of miR-27b in in vivo C57BL/6 mice impaired whole body glucose tolerance and adipose tissue insulin sensitivity. Furthermore, inhibition of miR-27b in HFD-induced insulin resistance mice model improved glucose tolerance and adipose tissue insulin sensitivity by increasing the expression of its target gene INSR in eWAT. Thus, our results indicate that miR-27b functions as a prime modulator of CI-induced IR via regulating the expression of INSR. KEY MESSAGES: miR-27b is upregulated in different in vitro and in vivo models of insulin resistance. miR-27b directly suppresses the expression of INSR by targeting 3'UTR of INSR. Modulation of miR-27b expression regulates insulin sensitivity by targeting INSR. PMID- 29455243 TI - 2018 International Olympic Committee consensus statement on prevention, diagnosis and management of paediatric anterior cruciate ligament (ACL) injuries. AB - In October 2017, the International Olympic Committee hosted an international expert group of physiotherapists and orthopaedic surgeons who specialise in treating and researching paediatric anterior cruciate ligament (ACL) injuries. Representatives from the American Orthopaedic Society for Sports Medicine, European Paediatric Orthopaedic Society, European Society for Sports Traumatology, Knee Surgery and Arthroscopy, International Society of Arthroscopy Knee Surgery and Orthopaedic Sports Medicine, Pediatric Orthopaedic Society of North America, and Sociedad Latinoamericana de Artroscopia, Rodilla y Deporte attended. Physiotherapists and orthopaedic surgeons with clinical and research experience in the field, and an ethics expert with substantial experience in the area of sports injuries also participated. Injury management is challenging in the current landscape of clinical uncertainty and limited scientific knowledge. Injury management decisions also occur against the backdrop of the complexity of shared decision-making with children and the potential long-term ramifications of the injury. This consensus statement addresses six fundamental clinical questions regarding the prevention, diagnosis, and management of paediatric ACL injuries. The aim of this consensus statement is to provide a comprehensive, evidence informed summary to support the clinician, and help children with ACL injury and their parents/guardians make the best possible decisions. PMID- 29455246 TI - Notch expressed by osteocytes plays a critical role in mineralisation. AB - : Notch is actively involved in various life processes including osteogenesis; however, the role of Notch signalling in the terminal mineralisation of bone is largely unknown. In this study, it was noted that Hey1, a downstream target of Notch signalling was highly expressed in mature osteocytes compared to osteoblasts, indicating a potential role of Notch in osteocytes. Using a recently developed thermosensitive cell line (IDG-SW3), we demonstrated that dentin matrix acidic phosphoprotein 1 (DMP1) expression was inhibited and mineralisation process was significantly altered when Notch pathway was inactivated via administration of N-[N-(3,5-Difluorophenacetyl)-L-alanyl]-S-phenylglycine t-butyl ester (DAPT), an inhibitor of Notch. Dysregulation of Notch in osteocyte differentiation can result in spontaneous deposition of calcium phosphate on collagen fibrils, disturbed transportation of intracellular mineral vesicles, alteration of mineral crystal structure, decreased bonding force between minerals and organic matrix, and suppression of dendrite development coupled with decreased expression of E11. In conclusion, the evidence presented here suggests that Notch plays a critical role in osteocyte differentiation and biomineralisation process. KEY MESSAGES: Notch plays a regulatory role in osteocyte phenotype. Notch modulates the mineralisation mediated by osteocytes. Notch activity influences the ultrastructural properties of bone mineralisation. PMID- 29455247 TI - Long-term experiences of pain after a fragility fracture. AB - : Little is known about long-term pain after a fragility fracture. In this secondary analysis, we determined that pain continues to influence many patients' lives more than 1 year after a fracture and that health care providers do not seem to adequately recognize or manage these long-term consequences. INTRODUCTION: We characterized perspectives on long-term pain among men and women who had sustained a fragility fracture. METHODS: We conducted a secondary analysis of qualitative data from 67 individuals recruited in three primary studies (47-89 years old; 55 women, 12 men). Eligible individuals from the primary studies were those who had reported pain related to their fracture beyond 6 months. Data about reported pain were re-analyzed using qualitative description as articulated by Sandelowski. RESULTS: Thirty-four individuals (47-89 years old; 4 men; 8 had sustained a vertebral fracture) reported pain related to their fracture in the primary studies. Thirty-one (91%) participants had sustained a fragility fracture at least 1 year previously (range 1-13 years). Patients described long-term pain beyond typical fracture healing times, generally unrelieved by analgesics, which affected their mobility, functional activity, independence, sleep, and energy. Health care providers were perceived to under estimate timelines regarding the decrease of post-fracture pain and to not manage that pain. Participants reported that pain management was inadequate and that they developed their own strategies to respond to it. CONCLUSIONS: Pain continues to influence many patients' lives more than 1 year after a fragility fracture. Patient narratives could be useful to help health care providers to better recognize and manage this long-term consequence of fractures. PMID- 29455248 TI - Are there effects of age, gender, height, and body fat on the functional muscle bone unit in children and adults? AB - : The aim was to describe the effect of age, gender, height, different stages of human life, and body fat on the functional muscle-bone unit. All these factors had a significant effect on the functional muscle-bone unit and should be addressed when assessing functional muscle-bone unit in children and adults. INTRODUCTION: For the clinical evaluation of the functional muscle-bone unit, it was proposed to evaluate the adaptation of the bone to the acting forces. A frequently used parameter for this is the total body less head bone mineral content (TBLH-BMC) determined by dual-energy X-ray absorptiometry (DXA) in relation to the lean body mass (LBM by DXA). LBM correlates highly with muscle mass. Therefore, LBM is a surrogate parameter for the muscular forces acting in everyday life. The aim of the study was to describe the effect of age and gender on the TBLH-BMC for LBM and to evaluate the impact of other factors, such as height, different stages of human life, and of body fat. METHODS: As part of the National Health and Nutrition Examination Survey (NHANES) study, between the years 1999-2006 whole-body DXA scans on randomly selected Americans from 8 years of age were carried out. From all eligible DXA scans (1999-2004), three major US ethnic groups were evaluated (non-Hispanic Whites, non-Hispanic Blacks, and Mexican Americans) for further statistical analysis. RESULTS: For the statistical analysis, the DXA scans of 8190 non-Hispanic White children and adults (3903 female), of 4931 non-Hispanic Black children and adults (2250 female) and 5421 of Mexican-American children and adults (2424 female) were eligible. Age, gender, body height, and especially body fat had a significant effect on the functional muscle-bone unit. CONCLUSIONS: When assessing TBLH-BMC for LBM in children and adults, the effects of age, gender, body fat, and body height should be addressed. These effects were analyzed for the first time in such a large cohort. PMID- 29455249 TI - Multiple vertebral fractures following osteoporosis treatment discontinuation: a case-report after long-term Odanacatib. AB - INTRODUCTION: Case reports of women sustaining multiple vertebral fractures (VF) soon afterdenosumab discontinuation are accumulating. METHODS: We report a woman with five new vertebral fractures in ~8 months following discontinuation of long term odanacatib (ODN), an experimental cathepsin K inhibitor. RESULTS: DXA examination demonstrated an ~12% decline in bone mineral density (BMD) and ~9% decline in trabecular bone score (TBS) since ODN discontinuation. Laboratory evaluation did not reveal a secondary cause of bone loss. CONCLUSIONS: This case mimics observations following denosumab discontinuation, but, to our knowledge, is the first reported with ODN and the first documenting substantial decline in TBS. While not directly clinically relevant as ODN is no longer being developed, this case raises the possibility that a syndrome of multiple vertebral fractures could follow discontinuation of various potent osteoporosis therapies that produce major BMD increases but do not have persisting bone effects (i.e., all non-bisphosphonates). Use of antiresorptive therapies to prevent rapid bone loss following discontinuation of potent bone active agents seems appropriate. Identification of those patients who could be at risk for the multiple VF syndrome is needed. PMID- 29455250 TI - Systematic review and meta-analysis of prevalence of sarcopenia in post acute inpatient rehabilitation. AB - : Sarcopenia is associated with poor function and increased risk of falls and disability. This work reports a systematic review and meta-analysis of prevalence of sarcopenia in post acute inpatient rehabilitation. Sarcopenia is found to be present in approximately 50% of rehabilitation patients and its prevalence may vary with admission diagnosis. PURPOSE: To conduct a systematic review and meta analysis of reported prevalence of sarcopenia in post acute inpatient rehabilitation. METHODS: Systematic review conducted according to PRISMA guidelines (PROSPERO registration number CRD42016054135). Databases searched MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Methodology Register, and CINAHL. Studies considered the following: published January 1988-February 2017. Key terms are as follows: "sarcopenia" AND "inpatient rehabilitation" OR "rehabilitation" AND/OR "prevalence". Abstracts and subsequently full studies reporting sarcopenia prevalence in adults admitted to rehabilitation reviewed irrespective of design, provided sarcopenia diagnosis included at least assessment of muscle mass. Random effect meta-analysis was conducted. Methodological quality assessment: Agency for Healthcare Research and Quality, US Department of Health and Human Services tool (MORE tool); Joanna Briggs Institute Prevalence Critical Appraisal Tool. RESULTS: Four hundred twenty-six studies identified during initial search, 399 excluded after reviewing titles and abstracts, 21 full text articles reviewed, and six studies met inclusion criteria. Patient populations: after hip fracture (five studies), general deconditioning (one study). Identified sarcopenia prevalence ranged from 0.28 to 0.69. Pooled sarcopenia prevalence obtained with random effect meta-analysis: 0.56 (95% CI 0.46-0.65), heterogeneity I2 = 92.9%. Main quality shortcomings: lack of reporting of inter- and intra-rater reliability, lack of generalizability to other rehabilitation populations. CONCLUSIONS: Original research examining sarcopenia prevalence in inpatient rehabilitation is scarce. Patient populations studied to date are not representative of general rehabilitation population with regard to both age and admission diagnoses. Sarcopenia may be present in approximately half of rehabilitation patients and its prevalence may vary with admission diagnosis. PMID- 29455251 TI - Establishing and characterizing lacrispheres from human lacrimal gland for potential clinical application. AB - PURPOSE: Lacrimal gland (LG) dysfunction leading to dry eye syndrome (DES) is an important cause of ocular morbidity. One of the potential and promising long-term management therapies for restoration of LG function could be transplantation of autologous ex vivo expanded stem cells. The present study was aimed at exploring the 2D and 3D cultures of human LG, identifying inherent stem cells and evaluating their secretory potential. METHODS: Fresh human lacrimal gland (HuLG) (n = 5) from patients undergoing therapeutic exenteration was harvested after ethical approval and informed consent. The gland was enzymatically digested and the isolated cells plated in Hepato-STIM media supplemented with l-glutamine, epidermal growth factor, fibroblast growth factor, and N-2 supplement. The native HuLG and the cultured spheres (DIV14-16) were evaluated for presence of stem cells (CD117 expression, quiescence, BrdU label retention, cell cycle, colony forming efficiency) and differentiation (secretion of tear proteins). RESULTS: Under the established culture conditions, suspension 3D cultures of human "lacrispheres" could be maintained and propagated for 3-4 weeks. The spheres consist of both acinar as well as ductal cells with evidence of stem cells (0.8 +/- 0.05% CD117+ cells), BrdU label retention (9.31 +/- 0.41%), G0/G1 profile similar to native lacrimal cells at isolation (76.9 versus 79.9%) and colony forming units (3.1%). The lacrispheres also secreted quantifiable levels of tear proteins (lysozyme, lactoferrin, scIgA) into the conditioned media. CONCLUSION: The study provides promising, first-of-its-kind evidence for the generation of lacrispheres from fresh HuLG, with enriched population of stem cells and secretory competent differentiated cells. The dual properties of these spheres make them a highly suitable source of transplantable cells for restoring the structure and function of damaged lacrimal gland. PMID- 29455252 TI - The effect of anti-tumor necrosis factor alpha agents on the outcome in pediatric uveitis of diverse etiologies. AB - PURPOSE: This study aimed to report the clinical outcome of children with uveitis treated with anti-tumor necrosis factor alpha (TNF-alpha) agents. METHODS: This included a retrospective cohort study. Children with uveitis treated with infliximab or adalimumab in 2008-2014 at five dedicated uveitis clinics were identified by database search. Their medical records were reviewed for demographic data, clinical presentation, ocular complications, and visual outcome. Systemic side effects and the steroid-sparing effect of treatment were documented. RESULTS: The cohort included 24 patients (43 eyes) of whom 14 received infliximab and 10 received adalimumab after failing conventional immunosuppression therapy. Mean age was 9.3 +/- 4.0 years. The most common diagnosis was juvenile idiopathic arthritis-related uveitis (n = 10), followed by Behcet's disease (n = 4), sarcoidosis (n = 1), and ankylosing spondylitis (n = 1); eight had idiopathic uveitis. Ocular manifestations included panuveitis in 20 eyes (46.5%), chronic anterior uveitis in 19 (44.2%), and intermediate uveitis in 4 (9.3%). The duration of biologic treatment ranged from 6 to 72 months. During the 12 months prior to biologic treatment, while on conventional immunosuppressive therapy, mean visual acuity deteriorated from 0.22 to 0.45 logMAR, with a trend of recovery to 0.25 at 3 months after initiation of biologic treatment, remaining stable thereafter. A full corticosteroid-sparing effect was demonstrated in 16 of the 19 patients (84.2%) for whom data were available. Treatment was well tolerated. CONCLUSIONS: Treatment of pediatric uveitis with anti-TNF-alpha agents may improve outcome while providing steroid-sparing effect, when conventional immunosuppression fails. The role of anti-TNF-alpha agents as first-line treatment should be further investigated in controlled prospective clinical trials. PMID- 29455253 TI - Incorporation of the fluoroless C-Arm Trainer at the American Urological Association hands on training percutaneous renal access. AB - OBJECTIVES: To assess for usefulness and validity evidence for incorporating the C-Arm Trainer (CAT) simulator into the annual AUA hands on course for training percutaneous nephrolithotomy (PCNL). MATERIALS AND METHODS: The course started with a didactic session followed by four stations for training the "bull's eye" technique using the CAT simulator. Each station included a pre-test, 30-min practice on the simulator, and post-test. All participants were assessed using a 4-item checklist. All participants were asked to fill in a qualitative self assessment questionnaire after the pre- and the post-test, and respond to a course evaluation questionnaire and post-course survey. RESULTS: A total of 38 physicians, who attended the hands on course, voluntarily participated in the study. Only 21.1% had previous practice on PCNL simulators. Compared with the results of the checklist total score and the qualitative self-assessment questionnaire scores after the pre-test, there was significant improvement in the checklist total score (p < 0.001), temporal demands (p = 0.003), situational stress (p = 0.003, and performance (0.003) after the post-test. A total of 14 (36%) participants responded to the course evaluation questionnaire, 50% evaluated the course as excellent, 28.6% as very good, and 21.4% as good. Unfortunately, only five (13%) participants responded to the post-course survey, 4/5 implemented the new competencies and knowledge into their practice, and 3/5 have attempted to obtain fluoroscopic guided PCA without assistance. CONCLUSION: The CAT simulator was considered useful for training the percutaneous renal access procedure. There was significant improvement in the qualitative and quantitative assessment parameters after the post-test compared with the pre test. PMID- 29455254 TI - Postpartum fatigue: assessing and improving the psychometric properties of the Fatigue Severity Scale. AB - A brief, reliable, and valid measure of postpartum fatigue in both clinical and research settings is much needed. This study assessed the psychometric properties of the Fatigue Severity Scale (FSS) among women with unsettled infants and fatigue. Rasch analysis identified an overall ceiling effect for the original FSS, as well as disordered response categories and/or poor fit for 4 items. A modified 5-item version of the FSS (FSS-5R) had improved psychometric properties. PMID- 29455255 TI - Fasting or Non-fasting Lipids for Atherosclerotic Cardiovascular Disease Risk Assessment and Treatment? AB - PURPOSE OF REVIEW: Dyslipidemia is a major modifiable risk factor for atherosclerotic cardiovascular disease (ASCVD); however, lipid testing for risk assessment and treatment surveillance has been underutilized. Several factors likely account for this, including the common practice of measuring lipid levels in the fasting state, which often necessitates that patients return for an additional visit. In this review, we evaluate potential advantages and cautions associated with measuring lipids in the non-fasting state. RECENT FINDINGS: There is similar performance with the use of either fasting or non-fasting total cholesterol and HDL cholesterol in ASCVD risk assessment. Observational studies demonstrate that in comparison to fasting levels, non-fasting triglycerides are approximately 20% higher on average, although the magnitude of difference is subject to substantial inter-patient variability. Higher triglycerides can lead to the under-estimation of low-density lipoprotein cholesterol (LDL-C) by approximately 10 mg/dL or more when calculated using the Friedewald equation. This is especially clinically relevant at low LDL-C levels, although a novel validated algorithm for LDL-C estimation largely overcomes this limitation. Non fasting lipid assessment is reasonable in many clinical circumstances given that ASCVD risk prediction is similar using fasting or non-fasting lipid values and because LDL-C can be accurately estimated using modern methods. Allowing the option for non-fasting lipid assessment can reduce a barrier to lipid testing and can facilitate a more convenient assessment of ASCVD risk with the ultimate potential effect of reducing the global burden of ASCVD. However, certain patients such as those with severe hypertriglyceridemias or high-risk patients being treated to low LDL-C levels may still need fasting lipid panels performed for precise diagnosis and to standardize therapeutic monitoring. PMID- 29455256 TI - Terrestrial-aquatic trophic linkages support fish production in a tropical oligotrophic river. AB - Despite low in situ primary productivity, tropical oligotrophic rivers support highly diverse fish assemblages and productive fisheries. This raises the question, what energy sources support fish production in these ecosystems? We sampled fish and food resources in the floodplain of a nearly pristine, large, oligotrophic river in western Amazonia. We combined data from stomach contents and stable isotopes to test the hypothesis that floodplain forests sustain fisheries in tropical oligotrophic rivers. Analysis of stomach contents from > 800 specimens of 12 omnivorous fish species demonstrated that during the annual flood, forest plant matter dominated diets. Yet, our isotope mixing models estimated that arthropods from the forest canopy made a greater proportional contribution to fish biomass. Most of these arthropods are entirely terrestrial and, therefore, serve as trophic links between forests and fishes. Our results suggest that forest vegetation, particularly fruits, may provide much of the energy supporting metabolism and arthropods contribute significant amounts of protein for somatic growth. Moreover, the importance of terrestrial arthropods in support of fish biomass in oligotrophic rivers depends on interactions between riparian vegetation, terrestrial arthropods and flood pulse dynamics affecting accessibility of arthropods to fishes. The apparent paradox of high fish diversity in an oligotrophic river with low primary productivity may be explained, at least partially, by dynamic terrestrial-aquatic trophic linkages. This study further emphasizes the importance of seasonally flooded forests for sustaining fisheries in the Amazon. PMID- 29455257 TI - Finite element analysis of hollow out-of-plane HfO2 microneedles for transdermal drug delivery applications. AB - Transdermal drug delivery (TDD) based on microneedles is an excellent approach due to its advantages of both traditional transdermal patch and hypodermic syringes. In this paper, the fabrication method of hollow out-of-layer hafnium oxide (HfO2) microneedles mainly based on deep reactive ion etching of silicon and atomic layer deposition of HfO2 is described, and the finite element analysis of the microneedles based on ANSYS software is also presented. The fabrication process is simplified by using a single mask. The finite element analysis of a single microneedle shows that the flexibility of the microneedles can be easily adjusted for various applications. The finite element analysis of a 3 * 3 HfO2 microneedle array applied on the skin well explains the "bed of nail" effect, i.e., the skin is not liable to be pierced when the density of microneedles in array increases. The presented research work here provides useful information for design optimization of HfO2 microneedles used for TDD applications. PMID- 29455258 TI - Effects of capsaicin on ovarian granulosa cell proliferation and apoptosis. AB - Capsaicin is the pungent ingredient in red peppers. Due to the effects on the sensory nerve fibers, capsaicin has been used to treat pain and inflammation associated with a variety of diseases including rheumatoid arthritis and diabetic neuropathy, obesity, and cardiovascular and gastrointestinal conditions. Despite the extensive publications on different systems, the studies of the effects on the ovary are very limited. The present study was conducted to examine the possible proliferative and/or apoptotic effects of various doses of capsaicin on primarily derived granulosa cells. In accordance with this purpose, ovarian granulosa cells were exposed to different doses of capsaicin for 24 and 48 h. The proliferative effects of capsaicin were examined by immunocytochemistry, immunofluorescence, and western blot using an antibody against proliferating cell nuclear antigen (PCNA) and cell viability assay (MTT). The effects on apoptosis were determined by immunocytochemistry and immunofluorescence using antibodies against cleaved caspase-3 and cleaved poly (ADP-ribose) polymerase (PARP). We showed that the number of apoptotic cells increased in a capsaicin dose and time dependent manners. We found that a low dose of CAP in 24 h administration was more effective on granulosa cell proliferation. Our results suggest that low-dose and short-term administration of CAP may have a positive effect on ovarian folliculogenesis. PMID- 29455259 TI - Influence of Zn(II) stress-induction on component variation and sorption performance of extracellular polymeric substances (EPS) from Bacillus vallismortis. AB - Bacillus vallismortis (B. vallismortis), an aerobic heterotrophic bacteria, was screened in a laboratory pilot study, to assess the interaction between the heavy metal Zn(II) and extracellular polymeric substances (EPS). The influence of Zn(II) stress on EPS production, component variation, and sorption performance, was investigated. The characteristics of B. vallismortis EPS formed under stress were analyzed using FTIR, 3D-EEM and XPS. EPS was used as an adsorbent and the adsorption capacity and adsorption behavior of EPS formed with and without Zn(II) stress, were compared and assessed. Results showed that the production of polysaccharides and proteins, the main components of EPS, were promoted under Zn(II) stress. The types of EPS functional groups observed remained the same with and without heavy metal stress, but their concentrations were increased. Due to stress-induction, the adsorption capacity of Zn-EPS was significantly enhanced compared with the control-EPS. Specific EPS produced by B. vallismortis in the presence of Zn(II) stress, could have a wide range of potential applications, allowing optimization and improvement of the capacity of EPS to remove heavy metals from effluent. PMID- 29455260 TI - Performance Evaluation of State-of-the-Art Local Feature Detectors and Descriptors in the Context of Longitudinal Registration of Retinal Images. AB - In this paper we systematically evaluate the performance of several state-of-the art local feature detectors and descriptors in the context of longitudinal registration of retinal images. Longitudinal (temporal) registration facilitates to track the changes in the retina that has happened over time. A wide number of local feature detectors and descriptors exist and many of them have already applied for retinal image registration, however, no comparative evaluation has been made so far to analyse their respective performance. In this manuscript we evaluate the performance of the widely known and commonly used detectors such as Harris, SIFT, SURF, BRISK, and bifurcation and cross-over points. As of descriptors SIFT, SURF, ALOHA, BRIEF, BRISK and PIIFD are used. Longitudinal retinal image datasets containing a total of 244 images are used for the experiment. The evaluation reveals some potential findings including more robustness of SURF and SIFT keypoints than the commonly used bifurcation and cross-over points, when detected on the vessels. SIFT keypoints can be detected with a reliability of 59% for without pathology images and 45% for with pathology images. For SURF keypoints these values are respectively 58% and 47%. ALOHA descriptor is best suited to describe SURF keypoints, which ensures an overall matching accuracy, distinguishability of 83%, 93% and 78%, 83% for without pathology and with pathology images respectively. PMID- 29455262 TI - Spatio-temporal variability of physico-chemical variables, chlorophyll a, and primary productivity in the northern Arabian Sea along India coast. AB - The present study attempts to understand the seasonal and spatial variations in the physico-chemical (temperature, pH, salinity, dissolved oxygen, and nutrients) and productivity characteristics of the northern Arabian Sea off the Indian coast. Samples were collected from four different sites off the Veraval coast. The values of the physical and chemical variables were higher during the summer season, whereas nutrient concentrations were high during the winter season due to the maturity of intake nutrients during post-monsoon and winter convective mixing during the northeast monsoon. The dissolved oxygen (DO) concentration was strongly and positively correlated with the net primary productivity (NPP) and chlorophyll a (Chl-a) content to support productivity along the region. Dissimilarity in study variables was observed between the inshore and offshore locations. Principal component analysis revealed a strong relationship between nutrients and productivity variables (Chl-a and NPP). Nutrient levels were high at inshore sites, which can be attributed to the heavy nutrient load from land based anthropogenic activities and impact due to natural processes like water mixing, sedimentation, and wave activities. Nutrients were strongly and positively correlated with the productivity variables, i.e., Chl-a and NPP. Chl-a positively correlated with NPP (r = 0.90), which indicates that it is a principle productivity pigment in the marine ecosystem. PMID- 29455261 TI - Phytoglobins regulate nitric oxide-dependent abscisic acid synthesis and ethylene induced program cell death in developing maize somatic embryos. AB - MAIN CONCLUSION: During maize somatic embryogenesis, suppression of phytoglobins (Pgbs) reduced ABA levels leading to ethylene-induced programmed cell death in the developing embryos. These effects modulate embryonic yield depending on the cellular localization of specific phytoglobin gene expression. Suppression of Zea mays phytoglobins (ZmPgb1.1 or ZmPgb1.2) during somatic embryogenesis induces programmed cell death (PCD) by elevating nitric oxide (NO). While ZmPgb1.1 is expressed in many embryonic domains and its suppression results in embryo abortion, ZmPgb1.2 is expressed in the basal cells anchoring the embryos to the embryogenic tissue. Down-regulation of ZmPgb1.2 is required to induce PCD in these anchor cells allowing the embryos to develop further. Exogenous applications of ABA could reverse the effects caused by the suppression of either of the two ZmPgbs. A depletion of ABA, ascribed to a down-regulation of biosynthetic genes, was observed in those embryonic domains where the respective ZmPgbs were repressed. These effects were mediated by NO. Depletion in ABA content increased the transcription of genes participating in the synthesis and response of ethylene, as well as the accumulation of ethylene, which influenced embryogenesis. Somatic embryo number was reduced by high ethylene levels and increased with pharmacological treatments suppressing ethylene synthesis. The ethylene inhibition of embryogenesis was linked to the production of reactive oxygen species (ROS) and the execution of PCD. Integration of ABA and ethylene in the ZmPgb regulation of embryogenesis is proposed in a model where NO accumulates in ZmPgb-suppressing cells, decreasing the level of ABA. Abscisic acid inhibits ethylene biosynthesis and the NO-mediated depletion of ABA relieves this inhibition causing ethylene to accumulate. Elevated ethylene levels trigger production of ROS and induce PCD. Ethylene-induced PCD in the ZmPgb1.1 suppressing line [ZmPgb1.1 (A)] leads to embryo abortion, while PCD in the ZmPgb1.2-suppressing line [ZmPgb1.2 (A)] results in the elimination of the anchor cells and the successful development of the embryos. PMID- 29455263 TI - Halobacterium salinarum storage and rehydration after spray drying and optimization of the processes for preservation of carotenoids. AB - Spray drying is appropriate for the preservation of halophilic microorganisms due to the nature of these microorganisms, as they survive in adverse environmental conditions by being encapsulated in salt crystals. Artificial neural networks were in this study used to optimize practically significant spray-drying regimes of the C50-carotenoids producer Halobacterium salinarum. Immediately after drying, the samples contained up to 54% halobacterial biomass and less than 5% moisture, and the level of preservation of carotenoids was 95-97%. The storage of biomass at 4 degrees C resulted in the gradual degradation of the carotenoids, which reached 58-64% in the best samples after 1 year. A comprehensive study of changes in halobacteria biomass after spray drying and the nature of the damage provided new data on the survival and preservation of cells and biologically active substances in the various spray-drying regimes and at different storage times. PMID- 29455264 TI - Mortality Rate and Predictors in Children Under 15 Years Old Who Acquired HIV from Mother to Child Transmission in Paraguay. AB - We estimated mortality rate and predictors of death in children and adolescents who acquired HIV through mother-to-child transmission in Paraguay. In 2000-2014, we conducted a cohort study among children and adolescents aged < 15 years. We abstracted data from medical records and death certificates. We used the Cox proportional hazards model for the multivariable analysis of mortality predictors. A total of 302 subjects were included in the survey; 216 (71.5%) were younger than 5 years, 148 (51.0%) were male, and 214 (70.9%) resided in the Asuncion metropolitan area. There were 52 (17.2%) deaths, resulting in an overall mortality rate of 2.06 deaths per 100 person-years. The children and adolescents with hemoglobin levels <= 9 g/dL at baseline had a 2-times higher hazard of death compared with those who had levels > 9 g/dL (HR 2.27, 95% CI 1.01-5.10). The mortality of HIV-infected children and adolescents in Paraguay is high, and anemia is associated with mortality. Improving prenatal screening to find cases earlier and improving pediatric follow-up are needed. PMID- 29455265 TI - Grit and Ambition are Associated with Better Neurocognitive and Everyday Functioning Among Adults Living with HIV. AB - Grit and ambition are psychological factors that may protect neurocognitive function among persons living with HIV (PLWH). We examined associations between grit, ambition, premorbid verbal intellectual function, and current neurocognitive and everyday functioning among PLWH and persons without HIV (HIV ). 120 PLWH and 94 HIV- adults completed the Grit Scale (includes total score and consistency of interests and perseverance of effort subscales), ambition scale, and a comprehensive neurobehavioral battery. PLWH had lower grit scores than HIV- adults. The two groups did not differ on ambition. No relationship was observed between grit and cognition among HIV- adults. Among PLWH, however, higher perseverance of effort and more ambition was related to better global neurocognitive functioning, and higher grit, but not ambition, was related to independence in daily functioning. Longitudinal studies are needed to elucidate these relationships over time and examine whether grit or ambition have protective effects on cognitive outcomes among PLWH. PMID- 29455266 TI - Inflammatory tenosynovitis and enthesitis induced by immune checkpoint inhibitor treatment. AB - Reports about immune-related adverse events (IrAEs) induced by immune checkpoint inhibitors (ICIs) have been increasing. Although the importance of understanding joint involvement and myalgia as an IrAE has grown, little is known about its characteristics. The aim of this study was to investigate the incidence and clinical characteristics of articular IrAEs. We reviewed 133 patients who were treated with ICIs in our institution and referred to our rheumatologic. Among them, 2 (1.5%) developed arthritis during the use of anti-PD-1 inhibitor, and there was one patient with joint pain after anti-PD-L1 inhibitor who was referred to our department from another institution. No patients had antecedent inflammatory arthritis or any relevant medical history. All 3 patients were negative for anti-nuclear antibody, rheumatoid factor, and anti-cyclic citrullinated peptide antibody. The ultrasonography showed tenosynovitis and enthesitis in both small and large joints with no or insignificant synovitis. Joint pain improved gradually within 6 months with only NSAIDs in 2 patients, and disappeared quickly in the other patient 2 weeks after 20 mg/day of predonisolone. Our report suggested diverse phenotypes of joint involvement and highlighted the importance of accumulating such patients. PMID- 29455267 TI - Reactive arthritis: update 2018. AB - At this time, reactive arthritis (ReA) is considered to be part of the spectrum of the spondyloarthritis, previously known as Reiter's syndrome, and refers to an infection induced systemic illness, characterized by a sterile synovitis occurring in a genetically predisposed individual, secondary to an infection localized in a distant organ/system, but also accompanied with multiple extra articular manifestations. PMID- 29455268 TI - Family history of cancer in first-degree relatives and risk of gastric cancer and its precursors in a Western population. AB - BACKGROUND: Family history may inform risks of gastric cancer and preneoplastic lesions. METHODS: We examined associations with history of cancer in first-degree relatives for 307 incident gastric cancer cases among 20,720 male smokers in a prospective study in Finland. Cox regression was used to calculate gastric cancer hazard ratios (HR) and 95% confidence intervals (95% CI). Logistic regression was used to estimate odds ratios (OR) and 95% CIs for low serum pepsinogen, a marker of gastric atrophy. RESULTS: Gastric cancer risk was associated with gastric cancer history in first-degree relatives overall (HR 1.56, 95% CI 1.15-2.12), in fathers (HR 1.67, 95% CI 1.09-2.55) and in siblings (HR 2.05, 95% CI 1.25-3.38). Associations were significant for noncardia (HR 1.83, 95% CI 1.30-2.57) but not cardia (HR 0.93, 95% CI 0.46-1.87) cancers, and marginal for both intestinal-(HR 1.53, 95% CI 0.92-2.55) and diffuse-type (HR 1.47, 95% CI 0.72-3.03) histologies. Family history of other cancer types was not associated with gastric cancer risk. Family history of gastric cancer was associated with low pepsinogen (OR 1.29, 95% CI 1.11-1.50). CONCLUSIONS: Family history of gastric cancer is strongly associated with specific subtypes of gastric cancer as well as with gastric atrophy, a risk factor for developing this malignancy. PMID- 29455270 TI - Ventricular Tachycardia Triggered by Loperamide and Famotidine Abuse. AB - A 32-year-old male developed recurrent ventricular tachycardia after taking mega doses of loperamide and famotidine in order to experience an opiate-like euphoric effect. He was taking up to 200 mg of loperamide and multiple doses of famotidine each day. He developed palpitations and syncope. Electrocardiography demonstrated ventricular tachycardia and QT interval prolongation (corrected QT interval was 597 ms). He was diagnosed with loperamide-induced QT prolongation resulting in incessant ventricular tachycardia. Loperamide was discontinued, and he was treated with electrolyte replacement, supportive care, and monitoring. After 5 days, his electrocardiogram (ECG) normalized and he had no more ventricular tachycardia. A Naranjo assessment score of 8 was obtained, indicating a probable relationship between QT prolongation and his use of loperamide. Large doses of loperamide can cause QT interval prolongation and life-threatening arrhythmias. These effects may be accentuated when histamine-2 receptor blockers are also abused. PMID- 29455269 TI - The efficacy and safety of targeted therapy with or without chemotherapy in advanced gastric cancer treatment: a network meta-analysis of well-designed randomized controlled trials. AB - BACKGROUND: Advanced gastric cancer (AGC) is a severe malignant tumor associated with high mortality. Targeted therapy is an important approach for improving the therapeutic effects of AGC treatment. This study evaluates the efficacy and safety of targeted agents for AGC patients. METHODS: PubMed, EmBase, and the Cochrane Library were searched for double-blind randomized controlled trials (RCTs) of AGC treatments published prior to July 2017. Progression-free survival (PFS), overall survival (OS), objective response rate (ORR), and severe adverse effects (AEs) were evaluated to determine the efficacy and safety of targeted agents. A network meta-analysis with a frequentist framework was performed to assess the effects of various targeted agents for AGC treatment. RESULTS: Our analysis included 16 articles involving 5371 patients and 11 types of agents. The network meta-analysis showed that apatinib (97.5%) was most likely to improve PFS, followed by regorafenib (86.3%) and rilotumumab (65.4%). Apatinib was similarly best for OS outcome, (95.5%) followed by rilotumumab (74.7%) and regorafenib (70%). Apatinib (89.6%) also had the best improvement on ORR, followed by rilotumumab (75.4%) and everolimus (68.4%). Bevacizumab (85.5%) was likely to get the lowest severe AEs, followed by sunitinib (63%). CONCLUSIONS: Apatinib, regorafenib, and rilotumumab improved patient PFS and OS. When combined with chemotherapy, ramucirumab and rilotumumab had high efficacy but low tolerability, and bevacizumab had moderate efficacy and tolerability for PFS. Without chemotherapy, ramucirumab and regorafenib had relatively high therapeutic efficacy tolerability for PFS. PMID- 29455271 TI - Progressive Supranuclear Palsy: an Update. AB - PURPOSE OF REVIEW: Progressive supranuclear palsy (PSP) is a 4R tau neuropathologic entity. While historically defined by the presence of a vertical supranuclear gaze palsy and falls in the first symptomatic year, clinicopathologic studies identify alternate presenting phenotypes. This article reviews the new PSP diagnostic criteria, diagnostic approaches, and treatment strategies. RECENT FINDINGS: The 2017 International Parkinson and Movement Disorder Society PSP criteria outline 14 core clinical features and 4 clinical clues that combine to diagnose one of eight PSP phenotypes with probable, possible, or suggestive certainty. Evidence supports the use of select imaging approaches in the classic PSP-Richardson syndrome phenotype. Recent trials of putative disease-modifying agents showed no benefit. The new PSP diagnostic criteria incorporating the range of presenting phenotypes have important implications for diagnosis and research. More work is needed to understand how diagnostic evaluations inform phenotype assessment and identify expected progression. Current treatment is symptomatic, but tau-based therapeutics are in active clinical trials. PMID- 29455272 TI - The outcome and timing of death of 17,767 nosocomial bloodstream infections in acute care hospitals in Finland during 1999-2014. AB - Few studies covering all patient groups and specialties are available regarding the outcome of nosocomial bloodstream infections (BSI). We analyzed the role of patient characteristics and causative pathogens of nosocomial BSIs reported by the hospitals participating in national surveillance in Finland during 1999-2014, in terms of outcome, with particular interest in those leading to death within 2 days (i.e. early death). National nosocomial BSI surveillance was laboratory based and hospital-wide. Data on nosocomial BSIs was collected by infection control nurses, and dates of death were obtained from the national population registry with linkage to national identity codes. A total of 17,767 nosocomial BSIs were identified; 557 BSIs (3%) were fatal within 2 days and 1150 (6%) within 1 week. The 1-month case fatality was 14% (2460 BSIs), and 23% of the deaths occurred within 2 days and 47% within 1 week. The patients who died early were older than those who survived > 28 days, and their BSIs were more often related to intensive care. Gram-positive bacteria caused over half of the BSIs of patients who survived, whereas gram-negative bacteria, especially Pseudomonas aeruginosa, caused more often BSIs of patients who died early, and fungi BSIs of patients who died within 1 week. A significant portion of patients with nosocomial BSIs died early, which underlines the importance of rapid recognition of BSI. Hospital-wide surveillance data of causative pathogens can be utilized when composing recommendations for empiric antimicrobial treatment in collaboration with clinicians, as well as when promoting infection prevention.

Optimal medical therapy remains the cornerstone of heart failure management but device-based therapies have been shown to contribute to morbidity and mortality reduction. RECENT FINDINGS: Multiple investigational trials had been conducted in the past decade that helped us better understand and manage heart failure. In this manuscript, we will discuss the major device related trials of year 2017 in the fields of defibrillators, hemodynamic monitoring, remote monitoring, autonomic nervous system modulation, ventricular assist devices, and device-based valvular heart disease management. Further research and trials in device-based therapies are needed to explore their long-term reduction in mortality and morbidity along with cost-effectiveness analyses in patients living with heart failure.

PMID- 29455275 TI - The effect of different levels of dietary restriction on glucose homeostasis and metabolic memory. AB - Over the past 50 years, dietary restriction (DR) has been shown to extend the life span of a wide variety of organisms. A hallmark feature of DR is improved glucose homeostasis resulting in increased glucose tolerance and insulin sensitivity of animals ranging from rodents to humans. In this study, we demonstrate the early effects of varying levels of DR on glucose tolerance. Within 10 days of 40% DR, glucose tolerance was significantly improved and by 120 days; 10 and 20% DR also showed enhanced glucose tolerance. All three levels of DR showed reduced adiposity, increased expression of genes involved in fat turnover, and a reduction in the expression for markers of inflammation. Studies have shown that mice fed a DR diet retained metabolic memory in terms of improved glucose tolerance even after DR is discontinued. We show that 40% DR not only has an early effect on glucose tolerance but also maintained it after DR was discontinued for 2 months. Therefore, improvement in glucose tolerance is brought about by all three levels of DR but the metabolic memory is not dose responsive.

AB - Keloid, a benign skin disorder, forms during wound healing in genetically susceptible individuals. To better control keloid and understand the molecular mechanisms, this study screened gene hypermethylations of GEO database microarray data on keloids and identified the hypermethylation of the secreted frizzled related protein-1 (SFRP1) promoter. Subsequently, hypermethylation and mRNA and protein levels were assessed in 57 cases of keloid vs. normal skin tissues. Fibroblasts from tissues were isolated for the assessment of gene regulation in vitro. The methods used were bioinformatic analysis, lentiviral infection carrying SFRP1 cDNA, qRT-PCR, western blot, immunohistochemistry, luciferase reporter assay, methylation-specific PCR and methylated DNA immunoprecipitation qPCR, ELISA, and/or 5-Aza-2'-deoxycytidine treatment. The data revealed that the SFRP1 promoter was hypermethylated in keloid tissues, compared with that in normal skin tissues. The SFRP1 promoter methylation contributed to the downregulation of SFRP1 mRNA and protein in keloid tissues and keloid fibroblasts. The 5-Aza treatment significantly upregulated SFRP1 mRNA and protein level in keloid fibroblasts. Furthermore, the knockdown of DNMT1 expression, and not the expression of DNMT3a or DMNT3b, was responsible for the hypermethylation of the SFRP1 promoter and upregulation of SFRP1 mRNA and protein in keloid fibroblasts. In addition, the infection of lentivirus carrying SFRP1 cDNA significantly inhibited the signaling activity of Wnt/beta-catenin and the mRNA and protein expression of beta-catenin and alpha-SMA in keloid fibroblasts. In summary, the lost SFRP1 expression-induced Wnt/beta-catenin signaling due to the hypermethylation of the SFRP1 promoter could associate with keloid development, suggesting that SFRP1 might be a therapeutic target for keloid treatment.

AB - We analyzed guava fruits (Psidium guajava L. cv. Red Suprema) from Cuba to determine their chemical composition, total antioxidant capacity, as well as their protective effect against oxidative damage using an in vitro model of human dermal fibroblasts. The guava fruit is a natural source of bioactive compounds, such as polyphenols, vitamin C, folates and beta carotenes with proven health benefits. Human dermal fibroblasts were pre-incubated with different concentrations of guava crude extract and then subjected to oxidative stress using the AAPH stressor. The number of apoptotic and dead cells, as well as the markers of oxidative damage such as lipid and protein oxidation significantly decreased when cells were pre-incubated with guava crude extract and then exposed to the stressor. The activity of antioxidant enzymes also improved when cells were pre-incubated with guava crude extract in comparison to cells subjected to stress without prior pre-incubation with the guava extract. The results obtained in this study highlight the health benefits of guava regarding oxidative stress, proving it to be an important source of bioactive compounds associated with important biological properties. PMID- 29455278 TI - A review of the design and modification of lactoferricins and their derivatives. AB - Lactoferricin (Lfcin), a multifunction short peptide with a length of 25 residues, is derived from the whey protein lactoferrin by acidic pepsin hydrolysis. It has potent nutritional enhancement, antimicrobial, anticancer, antiviral, antiparasitic, and anti-inflammatory activities. This review describes the research advantages of the above biological functions, with attention to the molecular design and modification of Lfcin. In this examination of design and modification studies, research on the identification of Lfcin active derivatives and crucial amino acid residues is also reviewed. Many strategies for Lfcin optimization have been studied in recent decades, but we mainly introduce chemical modification, cyclization, chimera and polymerization of this peptide. Modifications such as incorporation of D-amino acids, acetylation and/or amidation could effectively improve the activity and stability of these compounds. Due to their wide array of bio-functions and applications, Lfcins have great potential to be developed as biological agents with multiple functions involved with nutritional enhancement, as well as disease preventive and therapeutic effects. PMID- 29455279 TI - Divergent Selection of Pattern Recognition Receptors in Mammals with Different Ecological Characteristics. AB - Pattern recognition receptors (PRRs) are specialized receptors that represent a key component of the host innate immune system. Whether molecular evolutionary history of different PRR classes have involved different genetic mechanisms underlying diverse pathogen environment in mammals, and whether distinct ecology of mammals may have imposed divergent selective pressures on the evolution of the PRRs, remained unknown. To test these hypotheses, we investigated the characterization of 20 genes belonging to four PRR classes in mammals. Evidence of positive selection was found in most (17 of 20) PRR genes examined, and most positively selected sites (84%) undergoing radical changes were found to fall in important functional regions, consistent with the co-evolutionary dynamics between the hosts and their microbial counterparts. We found different evolutionary patterns in different PRR classes, with the highest level of positive selection in C-type lectin receptor (CLR) family, suggesting that the capability of CLRs in response to a wide variety of ligands might explain their malleability to selection pressures. Tests using branch models that partitioned the data along habitat and social behavior found significant evidence of divergent selective pressures of PRRs among mammalian groups. Interestingly, species-specific evolution was detected on RIG-I-like helicase genes (RLRs) in cetaceans, suggesting that RLRs might play a critical role in the defense against widespread marine RNA viruses during their divergence and radiation into marine habitats. This study provides a comprehensive look at the evolutionary patterns and implications of mammalian PRRs, and highlights the importance of ecological influences in molecular adaptation. PMID- 29455280 TI - A novel integrated strategy for the detection and quantification of the neurotoxin beta-N-methylamino-L-alanine in environmental samples. AB - We describe a set of new tools for the detection and quantification of beta-N methylamino-L-alanine (BMAA) which includes a novel stable isotope-labeled BMAA standard (13C3,15N2) and a chip-based capillary electrophoresis mass spectrometry platform for separation and detection. Baseline resolution of BMAA from its potentially confounding structural isomers N-2-aminoethylglycine (AEG) and 2,4 diaminobutyric acid (2,4-DAB) is achieved using the chip-based CE-MS system in less than 1 min. Detection and linearity of response are demonstrated across > 3.5 orders of dynamic range using parallel reaction monitoring (PRM). The lower limit of detection and quantification were calculated for BMAA detection at 40 nM (4.8 ng/mL) and 400 nM (48 ng/mL), respectively. Finally, the strategy was applied to detect BMAA in seafood samples purchased at a local market in Raleigh, NC where their harvest location was known. BMAA was detected in a sea scallop sample. Because the BMAA/stable isotope-labeled 13C3,15N2-BMAA (SIL-BMAA) ratio in the scallop sample was below the limit of quantification, a semiquantitative analysis of BMAA content was carried out, and BMAA content was estimated to be approximately 820 ng BMAA/1 g of wet scallop tissue. Identification was verified by high mass measurement accuracy of precursor (< 5 ppm) and product ions (< 10 ppm), comigration with SIL-BMAA spike-in standard, and conservation of ion abundance ratios for product ions between BMAA and SIL-BMAA. Interestingly, BMAA was not identified in the free protein fraction but only detected after protein hydrolysis which suggests that BMAA is tightly bound by and/or incorporated into proteins. Graphical abstract Utilization of novel 13C3,15N2-BMAA and chip-based CE-MS/MS for detection and quantification of BMAA in environmental samples. PMID- 29455281 TI - Sensitive colorimetric assay for uric acid and glucose detection based on multilayer-modified paper with smartphone as signal readout. AB - In this work, a multilayer-modified paper-based colorimetric sensing platform with improved color uniformity and intensity was developed for the sensitive and selective determination of uric acid and glucose with smartphone as signal readout. In detail, chitosan, different kinds of chromogenic reagents, and horseradish peroxidase (HRP) combined with a specific oxidase, e.g., uricase or glucose oxidase (GOD), were immoblized onto the paper substrate to form a multilayer-modified test paper. Hydrogen peroxide produced by the oxidases (uricase or GOD) reacts with the substrates (uric acid or glucose), and could oxidize the co-immoblized chromogenic reagents to form colored products with HRP as catalyst. A simple strategy by placing the test paper on top of a light emitting diode lamp was adopted to efficiently prevent influence from the external light. The color images were recorded by the smartphone camera, and then the gray values of the color images were calculated for quantitative analysis. The developed method provided a wide linear response from 0.01 to 1.0 mM for uric acid detection and from 0.02 to 4.0 mM for glucose detection, with a limit of detection (LOD) as low as 0.003 and 0.014 mM, respectively, which was much lower than for previously reported paper-based colorimetric assays. The proposed assays were successfully applied to uric acid and glucose detection in real serum samples. Furthermore, the enhanced analytical performance of the proposed method allowed the non-invasive detection of glucose levels in tear samples, which holds great potential for point-of-care analysis.

PMID- 29455282 TI - Molecularly imprinted vs. reversed-phase extraction for the determination of zearalenone: a method development and critical comparison of sample clean-up efficiency achieved in an on-line coupled SPE chromatography system. AB - Sample preparation prior to chromatographic separation plays an important role in the analytical process. To avoid time-consuming and manual handling sample-prep, automated on-line techniques such as on-line SPE-HPLC are therefore preferred. In this study, two different on-line extraction approaches for mycotoxin/endocrine disruptor zearalenone (ZEA) determination using either molecularly imprinted polymer (MIP) with selective cavities and binding sites for extraction or a reversed-phase sorbent C18 providing non-selective interactions have been developed, validated, and compared. The validation characteristics were compared and the two methods were evaluated as being almost equal in terms of linearity, repeatability, precision, and recovery. Recoveries were in the range of 99.0 100.1% and limits of detection were found the same for both methods (1.5 MUg L 1). Method precision calculated for spiked beer samples was better for C18 sorbent (2.5 vs. 5.4% RSD). No significant differences in the selectivity of either extraction method were observed. The possible reasons and further details associated with this finding are discussed. Finally, both validated methods were applied for the determination of ZEA contamination in beer samples. Due to ZEA's native fluorescence, chromatographic separation with fluorimetric detection (lambdaex = 270 nm and lambdaem, = 458 nm) was selected.

AB - Here, we utilized the ultrasonic emulsification technique to generate hyaluronic acid microspheres incorporating a fluorescence-based glucose biosensor. We synthesized a novel lanthanide ion luminophore based on Eu3+. Eu sulfosuccinimidyl dextran (Eu-dextran) and Alexa Fluor 647 sulfosuccinimidyl-ConA (Alexa Fluor 647-ConA) were encapsulated in hyaluronic acid hydrogel to generate microspheres. Glucose sensing was carried out using a fluorescence resonance energy transfer (FRET)-based assay principle. A proportional fluorescence intensity increase was found within a 0.5-10-mM glucose concentration range. The glucose-sensing strategy showed an excellent tolerance for potential interferents. Meanwhile, the fluorescent signal of hyaluronic acid microspheres was very stable after testing for 72 h in glucose solution. Overall, hyaluronic acid microspheres encapsulating sensing biomolecules offer a stable and biocompatible biosensor for a variety of applications including cell culture systems, tissue engineering, detection of blood glucose, etc. Graphical abstract We report an ingenious biosensor encapsulated in hyaluronic acid microspheres for monitoring of glucose. Glucose sensing is carried out using a fluorescence resonance energy transfer-based assay principle with a novel lanthanide ions luminophore. The glucose detection system has excellent biocompatibility and stability for monitoring of glucose. PMID- 29455284 TI - Speciation analysis of arsenic in seafood and seaweed: Part I-evaluation and optimization of methods. AB - Several extraction and chromatographic methods were evaluated to identify optimum conditions for arsenic speciation analysis in seafood and seaweed. The extraction systems, which include aqueous, aqueous-organic, acidic, basic, and enzymatic solutions, were examined for their efficiency in extracting arsenic from finfish, crustaceans, molluscs, and seaweed keeping the chemical forms of the native arsenicals intact. While dilute solutions of nitric acid, hydrochloric acid, and tetramethylammonium hydroxide (TMAH) extract high fractions of arsenic from most of the matrices, the extractants oxidized arsenite (As3+) to arsenate (As5+) and converted some arsenosugars and non-polar arsenicals to known and/or unknown forms. Hot water (90 degrees C) effectively maintained the integrity of the native arsenic species and enabled analysis of the extracts with no further manipulation than filtration and dilution. Stepwise extraction of water-soluble and non-polar arsenic with hot water and a mixture of dichloromethane and methanol, respectively, resulted in sufficiently quantitative (> 75%) arsenic extraction from seafood and seaweed. Anion and cation exchange chromatographic methods were optimized for separation and quantitation of the arsenicals extracted into hot water. The non-polar arsenicals were collectively determined after digesting the extract in acid. The application of the optimum extraction and chromatographic conditions was demonstrated by analyzing certified reference materials of tuna fish tissue (BCR 627), lobster hepatopancreas (TORT-2) and oyster tissue (SRM 1566b), and a sample of hijiki seaweed. For all the matrices, good agreement (80-92%) was found between the total water-soluble arsenic and the sum of the concentrations of the chromatographed species. Limits of quantification (LOQ) were in the range 4-11 ng g-1 for 16 arsenicals. PMID- 29455285 TI - Characterization of a novel miniaturized burst-mode infrared laser system for IR MALDESI mass spectrometry imaging. AB - Laser systems are widely used in mass spectrometry as sample probes and ionization sources. Mid-infrared lasers are particularly suitable for analysis of high water content samples such as animal and plant tissues, using water as a resonantly excited sacrificial matrix. Commercially available mid-IR lasers have historically been bulky and expensive due to cooling requirements. This work presents a novel air-cooled miniature mid-IR laser with adjustable burst-mode output and details an evaluation of its performance for mass spectrometry imaging. The miniature laser was found capable of generating sufficient energy for complete ablation of animal tissue in the context of an IR-MALDESI experiment with exogenously added ice matrix, yielding several hundred confident metabolite identifications. Graphical abstract The use of a novel miniature 2.94 MUm burst mode laser in IR-MALDESI allows for rapid and sensitive mass spectrometry imaging of a whole mouse. PMID- 29455286 TI - Prediction of biotransformation products of the fungicide fluopyram by electrochemistry coupled online to liquid chromatography-mass spectrometry and comparison with in vitro microsomal assays. AB - Biotransformation processes of fluopyram (FLP), a new succinate dehydrogenase inhibitor (SDHI) fungicide, were investigated by electrochemistry (EC) coupled online to liquid chromatography (LC) and electrospray mass spectrometry (ESI-MS). Oxidative phase I metabolite production was achieved using an electrochemical flow-through cell equipped with a boron-doped diamond (BDD) electrode. Structural elucidation and prediction of oxidative metabolism pathways were assured by retention time, isotopic patterns, fragmentation, and accurate mass measurements using EC/LC/MS, LC-MS/MS, and/or high-resolution mass spectrometry (HRMS). The results obtained by EC were compared with conventional in vitro studies by incubating FLP with rat and human liver microsomes (RLM, HLM). Known phase I metabolites of FLP (benzamide, benzoic acid, 7-hydroxyl, 8-hydroxyl, 7,8 dihydroxyl FLP, lactam FLP, pyridyl acetic acid, and Z/E-olefin FLP) were successfully simulated by EC/LC/MS. New metabolites including an imide, hydroxyl lactam, and 7-hydroxyl pyridyl acetic acid oxidative metabolites were predicted for the first time in our study using EC/LC/MS and liver microsomes. We found oxidation by dechlorination to be one of the major metabolism mechanisms of FLP. Thus, our results revealed that EC/LC/MS-based metabolic elucidation was more advantageous on time and cost of analysis and enabled matrix-free detection with valuable information about the mechanisms and intermediates of metabolism processes.

AB - New generation inert ionic liquid (iIL) GC columns IL60i, IL76i and IL111i, comprising phosphonium or imidazolium cationic species, were investigated for separation of fatty acid methyl esters (FAME). In general, the iIL phases provide comparable retention times to their corresponding conventional columns, with only minor selectivity differences. The average tailing factors and peak widths were noticeably improved (reduced) for IL60i and IL76i, while they were slightly improved for IL111i. Inert IL phase columns were coupled with conventional IL columns in comprehensive two-dimensional GC (GC * GC) with a solid-state modulator which offers variable modulation temperature (TM), programmable TM during analysis and trapping stationary phase material during the trap/release (modulation) process, independent of oven T and column sets. Although IL phases are classified as polar, relative polarity of the two phases comprising individual GC * GC column sets permits combination of less-polar IL/polar IL and polar IL/less-polar IL column sets; it was observed that a polar/less-polar column set provided better separation of FAME. A higher first dimension (1D) phase polarity combined with a lower 2D phase polarity, for instance 1D IL111i with 2D IL59 gave the best result; the greater difference in 1D/2D phase polarity results in increasing occupancy of peak area in the 2D space. The IL111i/IL59 column set was selected for analysis of fatty acids in fat and oil products (butter, margarine, fish oil and canola oil). Compared with the conventional IL111, IL111i showed reduced column bleed which makes this more suited to GC * GC analysis of FAME. The proposed method offers a fast profiling approach with good repeatability of analysis of FAME.

AB - The present study aimed to determine the serum trace elements (copper (Cu), zinc (Zn), calcium (Ca), magnesium (Mg)) along with erythrocyte carbonic anhydrase (CA) activity and effect of intervention with safe drinking water for 5 years in the school children of fluorosis endemic area. For this purpose, three categories of villages were selected based on drinking water fluoride (F): Category I (control, F = 1.68 mg/L), category II (affected F = 3.77 mg/L), and category III (intervention village) where initial drinking water F was 4.51 mg/L, and since the last 5 years, they were drinking water containing < 1.0 mg/L F. The results revealed that urinary F was significantly (P < 0.05) higher in category II compared to categories I and III. A significant (P < 0.05) increase in serum Cu and Mg was observed in category II compared to category I. Serum Zn and Ca was significantly (P < 0.05) decreased in categories II and III compared to category I. The erythrocyte CA activity was decreased in the category II compared to category I. However, in the category III, erythrocyte CA activity was comparable to the control group. In conclusion, F exposure altered elemental homeostasis which has restored to some extent on intervention by safe drinking water for 5 years in school-going children. PMID- 29455288 TI - Mycophenolate Mofetil Protects Septic Mice via the Dual Inhibition of Inflammatory Cytokines and PD-1. AB - Due to the imbalance between hyper-inflammation and hypo-inflammation, which are characterized by excessive cytokine productions and programmed death 1 (PD-1) upregulation, respectively, sepsis remains a highly lethal inflammatory syndrome with limited effective therapies. Mycophenolate mofetil (MMF), an immunosuppressant, has been reported to attenuate various inflammatory diseases. However, the role of MMF in sepsis therapy remains to be elucidated. C57BL-6J mice underwent cecal ligation and puncture (CLP) and were treated either with or without MMF. Survival rate and organ injuries were compared. Cytokine levels, bacteria clearance, apoptosis of spleen and peritoneal macrophages, and PD-1 expression were assessed. At the beginning of CLP, 60 mg/kg MMF administered by gavage significantly protected septic mice, which was evidenced by improved survival and attenuated organ injuries, decreased cytokines, lower bacterial loads, and alleviated immune cell apoptosis. In addition, immune cells in the MMF mice showed lower PD-1 expression and improved immune response to pathogeny stimuli. MMF protects septic mice via the dual inhibition of cytokine releasing and PD-1 expression. PMID- 29455290 TI - Laparoscopic hemi-splenectomy. AB - Laparoscopic splenectomy is now established as a safe and feasible procedure. However, it remains associated with some short- and long-term postoperative complications, especially infectious complications. To our knowledge, this is the first report (with video) focusing on the safety and feasibility of laparoscopic hemi-splenectomy and its surgical outcomes for the treatment of splenic abscesses causing septic emboli. This technique combines the immunological benefits of partial splenectomy and the postoperative benefits of a minimally invasive approach. Further studies are needed to standardize this technique and to assess its immunological and surgical benefits. PMID- 29455291 TI - The role of 'jackpot' stimuli in maladaptive decision-making: dissociable effects of D1/D2 receptor agonists and antagonists. AB - RATIONALE: Laboratory experiments often model risk through a choice between a large, uncertain (LU) reward against a small, certain (SC) reward as an index of an individual's risk tolerance. An important factor generally lacking from these procedures are reward-associated cues that may modulate risk preferences. OBJECTIVE: We tested whether the addition of cues signaling 'jackpot' wins to LU choices would modulate risk preferences and if these cue effects were mediated by dopaminergic signaling. METHODS: Three groups of rats chose between LU and SC rewards for which the LU probability of reward decreased across blocks. The unsignaled group received a non-informative stimulus of trial outcome. The signaled group received a jackpot signal prior to reward delivery and blackout on losses. The signaled-light group received a similar jackpot for wins, but a salient loss signal distinct from the win signal. RESULTS: Presenting win signals decreased the discounting of LU value for both signaled groups regardless of loss signal, while the unsignaled group showed discounting similar to previous research without cues. Pharmacological challenges with D1/D2 agonists and antagonists revealed that D1 antagonism increased and decreased sensitives to the relative probability of reward for unsignaled and signaled groups, respectively, while D2 agonists decreased sensitivities to the relative magnitude of reward. CONCLUSION: The results highlight how signals predictive of wins can promote maladaptive risk taking in individuals, while loss signals have reduced effect. Additionally, the presence of reward-predictive cues may change the underlying neurobehavioral mechanisms mediating decision-making under risk. PMID- 29455293 TI - Variations of transverse foramina in cervical vertebrae: what happens to the vertebral artery? AB - PURPOSE: The purpose of this study is to examine variations of the foramen transversarium and the vertebral artery in computed tomography angiographies (CTa) of the cervical spine, investigate their coexistence, and present possible considerations regarding such variations in spine surgical procedures. METHODS: Fifty CTa of the neck were retrospectively reviewed. Transverse and anteroposterior diameter of the foramen and diameter of the vertebral artery were measured. Variations of the foramen and the vertebral artery were detected. RESULTS: Cervical CTa of 32 males and 18 females (mean age 66.4 +/- 10.78 years), all belonging to the Indo-European race, were reviewed. Variations of the foramen transversarium were found in 17 vertebrae (4.85%) of 15 patients (30%). Duplication of the foramen was the most frequent variation, followed by the open foramen, the absence of the foramen, the triple foramen, and the hypoplastic foramen. Variations of the vertebral artery were found in 7 patients (14%) and asymmetry was found in 12 (24%) patients. Moreover, six patients presented with hypoplastic vertebral arteries (12%). When examining coexistence, 60% of patients exhibiting variations in the transverse foramen were also exhibiting variations or asymmetry in the vertebral artery, compared to 25.7% of patients with no foramen variations (p = 0.02). CONCLUSIONS: Vertebral artery injury is not common but may be a disastrous complication during cervical spine surgery. Proper preoperative planning is essential for any surgeon and exact knowledge of the anatomy in each patient is essential. This study strongly recommends the preoperative use of a CTa when suspicion of a variation is present and implied by a foramen variation.

PMID- 29455292 TI - Effects of the nicotinic agonist varenicline, nicotinic antagonist r-bPiDI, and DAT inhibitor (R)-modafinil on co-use of ethanol and nicotine in female P rats. AB - RATIONALE: Co-users of alcohol and nicotine are the largest group of polysubstance users worldwide. Commonalities in mechanisms of action for ethanol (EtOH) and nicotine proposes the possibility of developing a single pharmacotherapeutic to treat co-use. OBJECTIVES: Toward developing a preclinical model of co-use, female alcohol-preferring (P) rats were trained for voluntary EtOH drinking and i.v. nicotine self-administration in three phases: (1) EtOH alone (0 vs. 15%, two-bottle choice), (2) nicotine alone (0.03 mg/kg/infusion, active vs. inactive lever), and (3) concurrent access to both EtOH and nicotine. Using this model, we examined the effects of (1) varenicline, a nicotinic acetylcholine receptor (nAChR) partial agonist with high affinity for the alpha4beta2* subtype; (2) r-bPiDI, a subtype-selective antagonist at alpha6beta2* nAChRs; and (3) (R)-modafinil, an atypical inhibitor of the dopamine transporter (DAT). RESULTS: In phases 1 and 2, pharmacologically relevant intake of EtOH and nicotine was achieved. In the concurrent access phase (phase 3), EtOH consumption decreased while nicotine intake increased relative to phases 1 and 2. For drug pretreatments, in the EtOH access phase (phase 1), (R)-modafinil (100 mg/kg) decreased EtOH consumption, with no effect on water consumption. In the concurrent access phase, varenicline (3 mg/kg), r-bPiDI (20 mg/kg), and (R) modafinil (100 mg/kg) decreased nicotine self-administration but did not alter EtOH consumption, water consumption, or inactive lever pressing. CONCLUSIONS: These results indicate that therapeutics which may be useful for smoking cessation via selective inhibition of alpha4beta2* or alpha6beta2* nAChRs, or DAT inhibition, may not be sufficient to treat EtOH and nicotine co-use. PMID- 29455294 TI - Cervicothoracic spine duplication: a 10-year follow up of a neurological intact boy. AB - PURPOSE: Spine duplication is a very rare condition with the literature being composed of only case reports. All previously reported cases were thoracolumbar spine duplications. Here, we report cervicothoracic spine duplication in a neurological intact male. According to our knowledge, it is the first case in the literature of cervicothoracic spine duplication. CLINICAL PRESENTATION: A 3-year old patient presented to a primary physician with a complaint of short stature. He was referred to our department with suspected spinal deformity. Computerized tomography imaging revealed anterior bony structure duplication and posterior dysmorphic elements at the C5-T9 levels. Magnetic resonance imaging revealed a syrinx cavity which splits cord at the duplication level and the relation of the syrinx with posterior mediastinum through anterior bone defect. He was followed up for 10 years. CONCLUSION: In the literature, spine duplication has been classified as a severe form of split cord malformation because of the concurrence of bone duplication with split spinal cord malformation (SCM). This case presents a distinct form of SCM which shows non-duplicated dural tube as unclassified and cervicothoracic duplication level without neurological deficitis. Treatment of SCM was based on removal of splitting fibrous/osseous process. Neurologic intact spine duplication could be followed up without surgical intervention. PMID- 29455295 TI - Is extreme climate or moderate climate more conducive to longevity in China? AB - Climate is closely related to human longevity. In China, there are many climate types. According to national population censuses from 1982 to 2000, most provinces with a high ratio of centenarians are located in western and northwestern China far from the sea; these areas are characterized by a dry, cold climate, very high altitude, very high daily temperature range, strong winds, and partial hypoxia. Meanwhile, provinces with a high ratio of nonagenarians from 1982 to 2000 are located in southern China near the sea. Previous studies have attributed the high ratio of centenarians in western and northwestern China to the extreme local climate. However, centenarians in these areas decreased greatly in 2010, whereas residents in southern China frequently reached 90 to 100 years old in 2010. This study aims to explain this strange phenomenon and find whether extreme climate in Tibetan plateau and northwestern China or moderate climate in southern China is more conducive to longevity. The study found that mortality rate in Tibetan plateau is much higher than southern China, then a population evolution experiment was proposed to compare longevity indicators between low mortality rate and high mortality rate and shows that longevity indicators will decrease in the near future and increase above their original levels after several decades when the mortality rate is decreased. Results of this study show individuals in northwestern China do not live as long as those in eastern and southern China. A moderate climate is more conducive to longevity than extreme climate in China. The longevity of a region should be judged by long-term longevity indicators. PMID- 29455296 TI - Effects of balneotherapy and spa therapy on levels of cortisol as a stress biomarker: a systematic review. AB - Balneotherapy and spa therapy are well-known practices, even though limited evidence has been produced about their biological effects. This systematic review primarily aims at assessing if balneotherapy, mud/peloid therapy, and spa therapy may influence cortisol levels. Secondarily, it aims at understanding if these interventions may improve stress resilience. PubMed/Medline, Embase, and Cochrane Library were searched for relevant articles in English or Italian about studies involving healthy and sub-healthy subjects or patients with a diagnosed disease about effects of balneotherapy, mud/peloid therapy, and spa therapy on serum and salivary cortisol levels. Fifteen studies involving 684 subjects were included. Five studies investigated biological effects of balneotherapy alone. Two of them reported significant changes of cortisol levels in healthy participants. The other three studies reported no significant variations in patients with rheumatic conditions. No studies investigated biological effects of mud/peloid therapy alone. Ten studies investigated biological effects of spa therapy with or without included mud/peloid therapy, and in all but two studies, significant variations of cortisol levels were reported. Our main findings suggest that balneotherapy may have the potential to influence cortisol levels in healthy subjects, in such a way as to improve stress resilience. Spa therapy with or without included mud/peloid therapy demonstrated the same potential to influence cortisol levels also in sub-healthy subjects and in patients with a diagnosed disease. Therefore, balneotherapy and spa therapy may be considered as useful interventions for the management of stress conditions. Further investigation is needed because of limited available data.

AB - The Pan European Phenology (PEP) project is a European infrastructure to promote and facilitate phenological research, education, and environmental monitoring. The main objective is to maintain and develop a Pan European Phenological database (PEP725) with an open, unrestricted data access for science and education. PEP725 is the successor of the database developed through the COST action 725 "Establishing a European phenological data platform for climatological applications" working as a single access point for European-wide plant phenological data. So far, 32 European meteorological services and project partners from across Europe have joined and supplied data collected by volunteers from 1868 to the present for the PEP725 database. Most of the partners actively provide data on a regular basis. The database presently holds almost 12 million records, about 46 growing stages and 265 plant species (including cultivars), and can be accessed via http://www.pep725.eu/ . Users of the PEP725 database have studied a diversity of topics ranging from climate change impact, plant physiological question, phenological modeling, and remote sensing of vegetation to ecosystem productivity. PMID- 29455299 TI - Prostate-specific membrane antigen in breast cancer: a comprehensive evaluation of expression and a case report of radionuclide therapy. AB - PURPOSE: Prostate-specific membrane antigen (PSMA), a protein product of the folate hydrolase 1 (FOLH1) gene, is gaining increasing acceptance as a target for positron emission tomography/computer tomography (PET/CT) imaging in patients with several cancer types, including breast cancer. So far, PSMA expression in breast cancer endothelia has not been sufficiently characterized. METHODS: This study comprised 315 cases of invasive carcinoma of no special type (NST) and lobular breast cancer (median follow-up time 9.0 years). PSMA expression on tumor endothelia was detected by immunohistochemistry. Further, vascular mRNA expression of the FOLH1 gene (PSMA) was investigated in a cohort of patients with invasive breast cancer provided by The Cancer Genome Atlas (TCGA). RESULTS: Sixty percent of breast cancer cases exhibited PSMA-positive endothelia with higher expression rates in tumors of higher grade, NST subtype with Her2-positivity, and lack of hormone receptors. These findings were confirmed on mRNA expression levels. The highest PSMA rates were observed in triple-negative carcinomas (4.5 * higher than in other tumors). Further, a case of a patient with metastatic breast cancer showing PSMA expression in PET/CT imaging and undergoing PSMA radionuclide therapy is discussed in detail. CONCLUSIONS: This study provides a rationale for the further development of PSMA-targeted imaging in breast cancer, especially in triple-negative tumors. PMID- 29455298 TI - Patient-reported predictors of early treatment discontinuation: treatment-related symptoms and health-related quality of life among postmenopausal women with primary breast cancer randomized to anastrozole or exemestane on NCIC Clinical Trials Group (CCTG) MA.27 (E1Z03). AB - PURPOSE: Aromatase inhibitors are the most commonly prescribed adjuvant endocrine therapy for hormone-dependent early breast cancer in postmenopausal women. Among Canadian Cancer Trials Group MA.27 participants, anastrozole and exemestane had comparable 5-year event-free survival. This companion study examined differences in patient-reported treatment-related symptoms (TRS) and health-related quality of life (HRQL) among postmenopausal women randomized to anastrozole or exemestane. METHODS: MA.27 participants (N = 686, of 7576) randomized to 5 years of anastrozole (1 mg/day, n = 371, Arm A) or exemestane (25 mg/day, n = 315, Arm E) completed the 56-item Functional Assessment of Cancer Therapy-Endocrine Symptoms (FACT-ES) questionnaire to assess TRS and HRQL. The FACT-ES was completed at baseline, 3, 6, 12, and 24 months. RESULTS: No significant differences in FACT-ES median scores measuring TRS and HRQL were observed between treatment arms at any time point. Change in TRS from baseline was statistically significant at 3, 6, 12, and 24 months. HRQL was stable over time in both arms. Greater TRS burden was associated with poorer HRQL (coefficient = 0.57, p < 0.001). Twenty percent of patients discontinued AI therapy by month 24 and 32% discontinued AIs at 4 years. In both arms, patients reporting more side effect bother prior to initiating study treatment had a higher risk of discontinuing treatment before completing protocol therapy (hazard ratio [HR] 1.29, 95% CI 1.08 1.55, p = 0.01). CONCLUSIONS: TRS and HRQL were comparable between anastrozole and exemestane. TRS negatively affect HRQL. Women who report being bothered by treatment side effects prior to initiating an AI are at increased risk for early treatment discontinuation. PMID- 29455300 TI - Patterns of oral and dental care education and utilization in head and neck cancer patients. AB - PURPOSE: The purpose of this study was to examine patterns of oral health care among patients undergoing oral cancer therapy in order to better understand how oral care is being utilized, what types of providers are being utilized at various stages of cancer therapy, and assessing patients' satisfaction with the care they received at these stages. METHODS: An online survey was conducted via the Oral Cancer Foundation's support group message board. Participants were asked about their oral care immediately prior to cancer therapy, during cancer therapy, and post cancer therapy. The participants were also given the opportunity to provide open response feedback on their oral care which was analyzed qualitatively. RESULTS: Seventy-four participants completed the survey. Participants reported being informed that they needed to receive an oral evaluation 72.6 and 53.6% of the time in the pre- and post-treatment stages, respectively. Compliance with this recommendation was 71.2% pre cancer therapy but dropped precipitously to 49.2% post cancer therapy. Pre- and post-therapy oral care was provided most commonly by the patient's usual dentist 41.1 and 55.9%, respectively, with medical providers predominating the treatment phase, 77.7%. Patients reported dissatisfaction rates of 29.0, 20.6, and 21.0% sequentially. CONCLUSIONS: There is a general lack of consistency with how, when, and from whom oral cancer patients receive their oral health education. It is likely that this contributes to insufficient education resulting in high levels of patient dissatisfaction with their oral care. PMID- 29455301 TI - Sexual functioning among early post-treatment breast cancer survivors. AB - PURPOSE: This study aims (1) to estimate percentages of partnered women who are sexually active over the first 2 years post-breast cancer diagnosis; (2) to identify factors related to sexual inactivity; and (3) to evaluate separately, among both sexually active and inactive survivors, the relation between sexual problems and treatment-related variables, symptoms, and psychosocial factors. METHODS: Longitudinal observational study of breast cancer survivors recruited within 8 months of cancer diagnosis and followed for 18 months. The main outcome measures were (1) being sexually active/inactive in the past month and (2) sexual problems assessed with the four-item sexual problem domain of the Quality of Life in Adult Cancer Survivors (QLACS) scale. RESULTS: At baseline, 52.4% of women reported being sexually active in the past month. This percentage increased to 60.7% 18 months later. In multivariable repeated-measures analyses, age, past chemotherapy, depressive symptoms, and lower perceived attractiveness were related to inactivity. Sexually inactive women reported more problems on the QLACS than sexually active women. In stratified multivariable analyses, depressive symptoms were related to greater sexual problems for both sexually active and inactive women, as was vaginal dryness. Among the sexually active women, younger age at diagnosis, less illness intrusiveness, and lower perceived attractiveness were related to more problems. CONCLUSIONS: Research has shown that sexual functioning/sexual health are key aspects of quality of life for many cancer survivors, and are often not addressed by health care providers. Future studies should examine how such topics are handled by clinicians in their interactions with survivors. PMID- 29455302 TI - Patient experiences of a physiotherapy-led multidisciplinary rehabilitative intervention after successful treatment for oesophago-gastric cancer. AB - PURPOSE: To qualitatively explore the perceived impact of a 12-week rehabilitative intervention for oesophago-gastric cancer survivors on their physical, mental and social wellbeing. METHODS: Of the 21 participants who completed the intervention, 19 took part in a semi-structured focus group interview. Four audio-taped focus groups were held, ranging in size from two to eight participants. Focus groups were transcribed and analysed using a descriptive qualitative approach. RESULTS: At recruitment, participants were 23.5 +/- 15.2 months post-surgery and all had suboptimal fitness levels. Participants reported improvements in their physical capacity and ability to carry out activities of daily living during the intervention. These improvements led to increased confidence and social connectivity. Other participants were a valuable source of information and reassurance, while support from family members was variable. Future interventions should educate participants on how to maintain gains achieved during the intervention. CONCLUSIONS: Participating in an exercise based multidisciplinary rehabilitative intervention reduces isolation and helps oesophago-gastric cancer survivors to safely negotiate their physical, emotional and social needs as they move further down the path of recovery. PMID- 29455304 TI - Correction to: Characterization of bone morphology in CCN5/WISP2 knockout mice. AB - In the original publication's title CCN5/WISP5 should have been CCN5/WISP2. PMID- 29455303 TI - Extracellular matrix regulation of fibroblast function: redefining our perspective on skin aging. AB - The dermal extracellular matrix (ECM) comprises the bulk of skin and confers strength and resiliency. In young skin, fibroblasts produce and adhere to the dermal ECM, which is composed primarily of type I collagen fibrils. Adherence allows fibroblasts to spread and exert mechanical force on the surrounding ECM. In this state, fibroblasts display a "youthful" phenotype characterized by maintenance of the composition and structural organization of the dermal ECM. During aging, fibroblast-ECM interactions become disrupted due to fragmentation of collagen fibrils. This disruption causes loss of fibroblast spreading and mechanical force, which inextricably lead to an "aged" phenotype; fibroblasts synthesize less ECM proteins and more matrix-degrading metalloproteinases. This imbalance of ECM homeostasis further drives collagen fibril fragmentation in a self-perpetuating cycle. This article summarizes age-related changes in the dermal ECM and the mechanisms by which these changes alter the interplay between fibroblasts and their extracellular matrix microenvironment that drive the aging process in human skin. PMID- 29455305 TI - Photobiomodulation (PBM) therapy at 904 nm mitigates effects of exercise-induced skeletal muscle fatigue in young women. AB - Muscle fatigue is a process influenced by several mechanisms such as concentration of metabolic substrates, changes in blood flow, and increases in reactive oxygen species that impair contractile muscle function. In this context, photobiomodulation has been investigated for preventing muscle fatigue, with reports of positive effects on muscle performance. This study aimed to investigate the effects of 904-nm LASER photobiomodulation on rectus femoris muscle performance in young women. Eighteen young women participated in a randomized, participant and assessor-blinded crossover trial with placebo control. Active LASER (904 nm, 60 mW, 250 Hz, 3.6 J per diode, total dose of 129.6 J) intervention was applied prior to an isokinetic fatigue protocol consisting of a set of 60 concentric quadricep contractions at a constant dynamometer angular velocity of 180 degrees /s. Compared to placebo, LASER photobiomodulation significantly reduced muscle fatigue across a range of indicators including reduced ratings of perceived exertion (P = 0.0139), and increased electromyographic fatigue index (EFI) (P = 0.005). The isokinetic dynamometer performance analysis demonstrated that LASER photobiomodulation increased peak torque (P = 0.04), time to peak torque (P = 0.042), total work (P = 0.032), average power (P = 0.0007), and average peak torque (P = 0.019) between both experimental conditions. No significant difference was observed for work fatigue index (P = 0.29) or for lactate concentration (P > 0.05). Photobiomodulation at 904 nm was effective in reducing fatigue levels and increasing muscle performance in young active women but had no effect on lactate levels. PMID- 29455307 TI - Adansonia digitata and Adansonia gregorii fruit shells serve as a protection against high temperatures experienced during wildfires. AB - The thick and woody shell of the fruit of Adansonia species cannot be explained solely by adaptation to zoochory or hydrochory. Since the trunks of Adansonia possess a thick and fire-resistant bark and wildfires occur regularly in its habitat (savannah), we examined with the African Adanonia digitata and the Australian Adansonia gregorii whether the fruit offers protection against high heat typically experienced in wildfires. Heat-resistance tests were conducted by applying a simple heat test based on known temperature and temperature residence times occurring in savannah fires and complemented by tests to reveal the impact of heat on germination since long-term seed dormancy is known for Adansonia. Germination tests with acid treated and heat treated seeds were performed to establish if heat also increased germination rate as effectively as acid treatments have been found to do. Heat was found to increase germination rate, but not as effectively as treatment with acid, therefore fruits exposed to high temperatures experienced in wildfires may have a better chance of germination than fruits that were not exposed to wildfires. The ability of the investigated fruits to protect seeds from high temperatures suggests that wildfires may have played a role in the evolution of the hard-shell structure typically found in Adansonia. PMID- 29455306 TI - Dentinal tubule sealing effects of 532-nm diode-pumped solid-state laser, gallic acid/Fe3+ complex, and three commercial dentin desensitizers. AB - The purpose of this study was to compare dentinal tubule sealing effects of a 532 nm diode-pumped solid-state (DPSS) laser, gallic acid/Fe3+ complex, and three commercially available dentin desensitizers. Human premolars (n = 44) extracted for orthodontics had standardized cervical cavities prepared, etched (37% phosphoric acid) and randomly assigned to either a control (n = 4), or one of five treatment groups (n = 8/group). Desensitizing treatments were either a 532 nm DPSS laser, gallic acid/Fe3+ complex, oxalate-based Super SealTM (SS), DIOTM Enamel Coating Pen Pro Tooth (Dio), or adhesive-type Hybrid CoatTM (HC). Dentinal fluid flow (DFF) was monitored continuously in real time during the application of each desensitizing agent, by using a nanoliter-scaled fluid flow-measuring device. Following treatment, morphological changes on dentinal surfaces and within tubules were observed by scanning electron microscopy (SEM). DFF rates were significantly reduced after treatment in all experimental groups (P < 0.05), except SS (P > 0.05). The gallic acid/Fe3+ complex reduced DFF rates the most, and significantly (P < 0.05) more than the three commercial dentin desensitizers. There were no significant differences in DFF reduction rates between the gallic acid/Fe3+ complex and the DPSS laser groups (P > 0.05). There were no significant differences in DFF reduction rates among the three commercial dentin desensitizers (P > 0.05). SEM examination of treated dentin showed that the degree of occlusion of dentinal tubules correlated closely with the corresponding reduction in DFF rates. The gallic acid/Fe3+ complex and 532-nm DPSS laser were superior to other desensitizing methods in occluding dentinal tubules and reducing DFF rates. PMID- 29455308 TI - Fluid therapy and outcome: a prospective observational study in 65 German intensive care units between 2010 and 2011. AB - BACKGROUND: Outcome data on fluid therapy in critically ill patients from randomised controlled trials may be different from data obtained by observational studies under "real-life" conditions. We conducted this prospective, observational study to investigate current practice of fluid therapy (crystalloids and colloids) and associated outcomes in 65 German intensive care units (ICUs). In total, 4545 adult patients who underwent intravenous fluid therapy were included. The main outcome measures were 90-day mortality, ICU mortality and acute kidney injury (AKI). Data were analysed using logistic and Cox regression models, as appropriate. RESULTS: In the predominantly post operative overall cohort, unadjusted 90-day mortality was 20.1%. Patients who also received colloids (54.6%) had a higher median Simplified Acute Physiology Score II [25 (interquartile range 11; 41) vs. 17 (7; 31)] and incidence of severe sepsis (10.2 vs. 7.4%) on admission compared to patients who received exclusively crystalloids (45.4%). 6% hydroxyethyl starch (HES 130/0.4) was the most common colloid (57.0%). Crude rates of 90-day mortality were higher for patients who received colloids (OR 1.845 [1.560; 2.181]). After adjustment for baseline variables, the HR was 1.666 [1.405; 1.976] and further decreased to indicate no associated risk (HR 1.003 [0.980; 1.027]) when it was adjusted for vasopressor use, severity of disease and transfusions. Similarly, the crude risk of AKI was higher in the colloid group (crude OR 3.056 [2.528; 3.694]), after adjustment for baseline variables OR 1.941 [1.573; 2.397], and after full adjustment OR 0.696 [0.629; 0.770]), the risk of AKI turned out to be reduced. The same was true for the subgroup of patients treated with 6% HES 130/0.4 (crude OR 1.931 [1.541; 2.419], adjusted for baseline variables OR 2.260 [1.730; 2.953] and fully adjusted OR 0.800 [0.704; 0.910]) as compared to crystalloids only. CONCLUSIONS: The present analysis of mostly post-operative patients in routine clinical care did not reveal an independent negative effect of colloids (mostly 6% HES 130/0.4) on renal function or survival after multivariable adjustment. Signals towards a reduced risk in subgroup analyses deserve further study. Trial registration ClinicalTrials.gov Identifier: NCT01122277, registered May 11th, 2010. PMID- 29455309 TI - Right heart failure caused by direct pressure of distal arch aneurysm. AB - We report a rare case of right heart failure caused by distal aortic aneurysm. Although aortopulmonary fistula is a common complication of giant aortic arch aneurysm, right heart failure caused by mechanical pressure by aneurysm is very rare. A 79-year-old female patient presented dyspnea. Contrast computed tomography (CT) of the thorax delineated a 78 mm aortic arch aneurysm pressing the main to left pulmonary artery and a 40 mm pericardial effusion at maximum depth at posterior side. Echocardiography showed the acceleration flow from main to left pulmonary artery and moderate pulmonary hypertension. Left ventricular function, however, was preserved. We diagnosed right heart failure caused by giant aortic arch aneurysm and performed emergency aortic arch aneurysm replacement. After the operation, pulmonary artery pressure decreased and right heart failure improved. PMID- 29455310 TI - Germans learn how to save lives: a nationwide CPR education initiative. AB - BACKGROUND: Sudden cardiac death is one of the most frequent causes of death in Germany and the third leading cause of death in the industrialized world. Yet, the percentage of people providing first aid in the case of sudden cardiac arrest in Germany is alarmingly low by international comparison. Training Germans or reminding them of the simple but effective steps of resuscitation, so that everybody can save a live in an emergency. METHODS: For the campaign 'Resuscitation Week', physicians and paramedics trained passers-by in cardiovascular resuscitation free of charge. Skills were evaluated before and after the instruction by means of a questionnaire. RESULTS: Three hundred three people aged between 9 and 89 years were trained and evaluated. Forty-nine passers by had never participated in a resuscitation course, and 46.8% had participated in a course more than 20 years ago. Before the instruction, 41.6% of the passers by were confident to be capable of resuscitating a person; after the instruction, however, this percentage had risen to 100%! CONCLUSIONS: Saving a life is simple, but one has to know what to do in the case of sudden cardiac arrest. The German population is being gradually trained in resuscitation using campaigns such as 'Resuscitation Week' and 'Kids Save Lives' to break down barriers in the long term. However, lives are not only saved by training but also by refreshing knowledge and skills; thus, a further effective approach may be training all holders of a driving license in cardiopulmonary resuscitation in intervals of 5 years. PMID- 29455311 TI - Accelerated molecular breeding of a novel P/TGMS line with broad-spectrum resistance to rice blast and bacterial blight in two-line hybrid rice. AB - BACKGROUND: Breeding two-line hybrid rice with disease resistance is an effective approach to stabilize rice yield in commercial rice production of China. RESULTS: We improved the blast and bacterial blight resistance of Guangzhan63-4S, an elite photoperiod- and thermo-sensitive male sterile (P/TGMS) line widely used in two line hybrid rice, by introducing the R genes Pi2 and Xa7 conferring resistance to rice blast and bacterial blight, respectively. Through the backcrossing and gene pyramiding breeding coupled with molecular marker-assisted selection, a new P/TGMS line Hua1228S carrying Pi2, Xa7, and tms5 was developed. Based on 200,000 SNP markers by next-generation sequencing, Hua1228S covered 87.6% of the recurrent genome, as well as 4.5% of the donor genome from VE6219 and 7.9% from YR7029-39. When infected with seven tested Xanthomonas oryzae pv. oryzae strains, Hua1228S conferred high resistance (0 level) to six bacterial blight strains. Moreover, Hua1228S showed broad-spectrum resistance to rice blast isolates with a high resistance frequency of 90.91%. High levels of resistance to leaf blast and neck blast were observed under heavy disease pressure in natural field. Importantly, Hua1228S showed identical fertility-sterility alteration pattern to Guangzhan63-4S. Thus, two hybrid combinations Hua Liangyou 2821 and Hua Liangyou 284 derived from Hua1228S exhibited enhanced resistance and higher yield compared with the control variety Feng Liangyou 4. CONCLUSIONS: These results indicate that Hua1228S has tremendous potentiality to increase and stabilize the rice yield, through the introgression of two R genes by marker-assisted selection strategy.

PMID- 29455313 TI - [18F]FDG PET/MR enterography for the assessment of inflammatory activity in Crohn's disease: comparison of different MRI and PET parameters. AB - PURPOSE: To evaluate the diagnostic performance of integrated whole-body positron emission tomography (PET)/magnetic resonance (MR) enterography in patients with Crohn's disease (CD). METHODS: Fifty patients with known CD and recurrent symptoms underwent ileocolonoscopy (reference standard) as well as PET/MR enterography. Seven ileocolonic segments were endoscopically analysed using the Simplified Endoscopic Activity Score for Crohn's Disease (SES-CD) and additionally classified into three categories of inflammation (none, mild to moderate and severe ulcerative inflammation). A total of 14 PET/MR parameters were applied for the assessment of inflamed segments. Contingency tables and the chi-squared test were used for the analysis of qualitative parameters, and the Mann-Whitney U test and receiver operating characteristic (ROC) curve for the analysis of quantitative parameters. The PET/MR parameters were ranked according to their diagnostic value by random forest classification. Correlations between PET/MR parameters and the severity of inflammation on endoscopy and SES-CD were tested using Spearman's rank correlation test. RESULTS: A total of 309 segments could be analysed. Based on multivariate regression analysis, wall thickness and the comb sign were the most important parameters for predicting segments with active inflammation of any type. SUVmax ratio of the bowel segment (relative to SUVmax of the liver) was the most important parameter for detecting segments with severe ulcerative inflammation. Wall thickness was the only parameter that moderately correlated with inflammation severity on endoscopy as well as with SES CD (rho = 0.56 and 0.589, both p < 0.001). CONCLUSION: PET/MR enterography is an excellent noninvasive diagnostic method, and both MR parameters and PET findings provided high accuracy in detecting inflamed segments.

PMID- 29455315 TI - Mitogenomes of two neotropical bird species and the multiple independent origin of mitochondrial gene orders in Passeriformes. AB - At least four mitogenome arrangements occur in Passeriformes and differences among them are derived from an initial tandem duplication involving a segment containing the control region (CR), followed by loss or reduction of some parts of this segment. However, it is still unclear how often duplication events have occurred in this bird order. In this study, the mitogenomes from two species of Neotropical passerines (Sicalis olivascens and Lepidocolaptes angustirostris) with different gene arrangements were first determined. We also estimated how often duplication events occurred in Passeriformes and if the two CR copies demonstrate a pattern of concerted evolution in Sylvioidea. One tissue sample for each species was used to obtain the mitogenomes as a byproduct using next generation sequencing. The evolutionary history of mitogenome rearrangements was reconstructed mapping these characters onto a mitogenome Bayesian phylogenetic tree of Passeriformes. Finally, we performed a Bayesian analysis for both CRs from some Sylvioidea species in order to evaluate the evolutionary process involving these two copies. Both mitogenomes described comprise 2 rRNAs, 22 tRNAs, 13 protein-codon genes and the CR. However, S. olivascens has 16,768 bp showing the ancestral avian arrangement, while L. angustirostris has 16,973 bp and the remnant CR2 arrangement. Both species showed the expected gene order compared to their closest relatives. The ancestral state reconstruction suggesting at least six independent duplication events followed by partial deletions or loss of one copy in some lineages. Our results also provide evidence that both CRs in some Sylvioidea species seem to be maintained in an apparently functional state, perhaps by concerted evolution, and that this mechanism may be important for the evolution of the bird mitogenome. PMID- 29455317 TI - Genetic zygosity of mature ovarian teratomas, struma ovarii, and ovarian carcinoids. AB - Although ovarian monodermal teratomas, including struma ovarii and carcinoids, are closely associated with mature teratomas, their genetic basis is poorly understood. A series of mature and monodermal ovarian teratomas were analyzed by short tandem repeat genotyping to evaluate their genetic zygosity and its associations. Informative DNA genotyping data were obtained for ten mature teratomas, six struma ovarii, and three carcinoids (one insular, one trabecular, and one mucinous). A homozygous genotype was present in five of the ten (50%) mature teratomas, three of the six (50%) struma ovarii, and one of the three (33%) ovarian carcinoids. There was no significant difference in genetic zygosity between mature and monodermal teratomas. Patients' age was not correlated with the genetic zygosity: the youngest age in the homozygous tumor group of patients was 4 years. It is suggested that an oocyte after meiosis I, which has escaped from meiotic arrest, is a significant cause of these tumors. Although one mature teratoma was a rare case with lactating adenoma-like breast tissue, its genetic zygosity was concordant with that of the surrounding teratomatous tissue. In one ovarian carcinoid, the carcinoid and accompanying teratomatous components showed matching zygosity at all but one locus: the carcinoid was heterozygous but teratoma was homozygous at one pericentromeric locus. This suggests that not all carcinoids are secondary neoplasms arising from a fully developed mature teratoma: some are neoplasms deviating from a developing mature teratoma. PMID- 29455316 TI - Investigation of major genetic alterations in neuroblastoma. AB - Neuroblastoma (NB) is the most common extracranial solid tumor in childhood. This malignancy shows a wide spectrum of clinical outcome and its prognosis is conditioned by manifold biological and genetic factors. We investigated the tumor genetic profile and clinical data of 29 patients with NB by multiplex ligation dependent probe amplification (MLPA) to assess therapeutic risk. In 18 of these tumors, MYCN status was assessed by fluorescence in situ hybridization (FISH). Copy number variation was also determined for confirming MLPA findings in two 6p loci. We found 2p, 7q and 17q gains, and 1p and 11q losses as the most frequent chromosome alterations in this cohort. FISH confirmed all cases of MYCN amplification detected by MLPA. In view of unexpected 6p imbalance, copy number variation of two 6p loci was assessed for validating MLPA findings. Based on clinical data and genetic profiles, patients were stratified in pretreatment risk groups according to international consensus. MLPA proved to be effective for detecting multiple genetic alterations in all chromosome regions as requested by the International Neuroblastoma Risk Group (INRG) for therapeutic stratification. Moreover, this technique proved to be cost effective, reliable, only requiring standard PCR equipment, and attractive for routine analysis. However, the observed 6p imbalances made PKHD1 and DCDC2 inadequate for control loci. This must be considered when designing commercial MLPA kits for NB. Finally, four patients showed a normal MLPA profile, suggesting that NB might have a more complex genetic pattern than the one assessed by presently available MLPA kits. PMID- 29455318 TI - Expression of terminal deoxynucleotidyl transferase (TdT) in classical seminoma: a potential diagnostic pitfall. AB - Seminomas are the most frequent testicular tumors and in spite of specific markers some histological subtypes can be diagnostically challenging due to the potential overlap of morphologic features and a variant antigen expression. Terminal deoxynucleotidyl transferase (TdT) is a DNA polymerase present in hematogones, thymic T cells, lymphoblastic lymphoma/leukemia (LBL), and in some cases of acute myeloid leukemia but so far has not been described to be expressed in seminomas. After observing a reactivity of TdT in one case of seminoma, we analyzed ten additional tumors by immunohistochemistry to determine their spectrum of reactivity for TdT. In all seminoma cases investigated (10/10) as well as in two tumor-associated germ cell neoplasias in situ (2/2) the TdT staining intensity was variable but was often moderate to strong and restricted to the nucleus. We conclude that TdT expression in seminomas could represent a diagnostic pitfall in the differential diagnosis of LBL, particularly because both may lack CD45 and/or CD20 expression and-concerning relapse in long-term survivors of testicular cancer-LBL is the most frequent secondary neoplasm in the patients. PMID- 29455319 TI - Development and Pilot Testing of a Decision Aid for Genomic Research Participants Notified of Clinically Actionable Research Findings for Cancer Risk. AB - Germline genomic testing is increasingly used in research to identify genetic causes of disease, including cancer. However, there is evidence that individuals who are notified of clinically actionable research findings have difficulty making informed decisions regarding uptake of genetic counseling for these findings. This study aimed to produce and pilot test a decision aid to assist participants in genomic research studies who are notified of clinically actionable research findings to make informed choices regarding uptake of genetic counseling. Development was guided by published literature, the International Patient Decision Aid Standards, and the expertise of a steering committee of clinicians, researchers, and consumers. Decision aid acceptability was assessed by self-report questionnaire. All 19 participants stated that the decision aid was easy to read, clearly presented, increased their understanding of the implications of taking up research findings, and would be helpful in decision making. While low to moderate levels of distress/worry were reported after reading the booklet, a majority of participants also reported feeling reassured. All participants would recommend the booklet to others considering uptake of clinically actionable research findings. Results indicate the decision aid is acceptable to the target audience, with potential as a useful decision support tool for genomic research participants. PMID- 29455320 TI - Elevated serum Krebs von den Lungen-6 in systemic sclerosis: a marker of lung fibrosis and severity of the disease. AB - OBJECTIVES: We aimed to assess the clinical significance of Krebs von den Lungen 6 (KL-6) in the diagnosis and severity of interstitial lung disease (ILD) in a French cohort of patients with systemic sclerosis (SSc). METHODS: Serum KL-6 concentrations were measured with chemiluminescent enzyme immunoassay (CLEIA) in 75 SSc patients. Patients were divided into two groups according to the presence of interstitial lung disease (SSc-ILD versus SSc-without ILD) on chest High Resolution Computed Tomography. Pulmonary function tests, main manifestations and severity of the lung disease (Medsger's severity scale) were collected. RESULTS: KL-6 serum concentrations were significantly higher in SSc-ILD patients than in those without ILD (p < 10-4) and were inversely correlated with forced vital capacity, total lung capacity and diffuse lung capacity of carbon monoxide. Serum KL-6 level superior to 872 U/ml appeared as the optimal cut-off value associated with ILD. Patients with a restrictive pulmonary syndrome and dyspnoea had significant higher KL-6 serum concentrations. SSc patients with anti topoisomerase 1 antibodies had higher KL-6 serum levels than patients with anti centromere antibodies (p < 10- 4). ILD and anti-topoisomerase 1 antibodies were independent factors associated with KL-6 in multivariate analysis. Interestingly, KL-6 serum concentrations positively increased with the patient lung severity. CONCLUSIONS: Our study confirms that KL-6 is an accurate biomarker for the diagnosis of SSc-ILD in a French cohort of patients. High KL-6 levels should prompt physicians to assess ILD with pulmonary imaging and pulmonary functions tests. Prospective clinical studies are still required to determine whether levels of KL-6 might predict progression of ILD as well as its usefulness in the timing of therapeutic intervention. PMID- 29455321 TI - Respiratory quotient estimations as additional prognostic tools in early septic shock. AB - Central venous-to-arterial carbon dioxide difference (PcvaCO2), and its correction by the arterial-to-venous oxygen content difference (PcvaCO2/CavO2) have been proposed as additional tools to evaluate tissue hypoxia. Since the relationship between pressure and content of CO2 (CCO2) might be affected by several factors, some authors advocate for the use of CcvaCO2/CavO2. The aim of the present study was to explore the factors that might intervene in the difference between PcvaCO2/CavO2 and CcvaCO2/CavO2, and to analyze their association with mortality. Observational study in a 30-bed mixed ICU. Fifty-two septic shock patients within the first 24 h of ICU admission were studied. After restoration of mean arterial pressure, hemodynamic and metabolic parameters were evaluated. A total of 110 sets of measurements were performed. Simultaneous PcvaCO2/CavO2 and CcvaCO2/CavO2 values were correlated, but agreement analysis showed a significant proportional bias. The difference between PcvaCO2/CavO2 and CcvaCO2/CavO2 was independently associated with pH, ScvO2, baseline CcvaCO2/CavO2 and hemoglobin. A stepwise regression analysis showed that pH was the single best predictor for the magnitude of such difference, with very limited effect of other variables. At inclusion, variables associated with ICU-mortality were lactate, pH, PcvaCO2/CavO2, and the difference between PcvaCO2/CavO2 and CcvaCO2/CavO2. Initial ScvO2, PcvaCO2, CcvaCO2/CavO2, and cardiac index were not different in survivors and non-survivors. In a population of early septic shock patients, simultaneous values of PcvaCO2/CavO2 and CcvaCO2/CavO2 were not equivalent, and the main determinant of the magnitude of the difference between these two parameters was pH. The PcvaCO2/CavO2 ratio was associated with ICU mortality, whereas CcvaCO2/CavO2 was not. PMID- 29455322 TI - A novel device for air removal from vascular access line: a bench study. AB - Efficient air removal from a vascular access line is a key step to prevent air embolism. Existing devices, especially for rapid infusers, are far from optimum. In this study, we developed a novel device, vascular access line air removal device (VALARD), and compared its efficiency of air removal and pause time of forward bulk flow with a commonly used device, the Belmont pump. Part I experiment, saline was infused at a forward bulk flow rate of 250, 500, and 750 mL/min. Meanwhile, air was introduced into the infusion line at a rate of 5, 10, and 15 mL/min for each bulk flow rate. Air bubbles > 10 uL downstream from either the VALARD or the Belmont pump and the fraction of pause time of the forward bulk flow were determined. Part II experiment, 120 mL of air was rapidly introduced into the VALARD at a bulk flow rate of about 500 mL/min. Air bubbles > 10 uL downstream from the VALARD, fraction of pause time of the forward bulk flow, and the transit time of the 120 mL of air at the working chamber were recorded. The VALARD: no air bubbles > 10 uL were detected during any tested combination of air injection and bulk flow rates without pause of forward flow. The Belmont pump: air bubbles > 10 uL were detected in 60% of the tests with pause of the forward flow. The VALARD eliminates air efficiently without pause of the forward bulk flow. Further clinical trials are needed to compare the VALARD with other devices and to assess its efficiency, safety, and user friendliness. PMID- 29455324 TI - Genetic diversity and phylogenetic analysis of Aleutian mink disease virus isolates in north-east China. AB - Aleutian mink disease is the most important disease in the mink-farming industry worldwide. So far, few large-scale molecular epidemiological studies of AMDV, based on the NS1 and VP2 genes, have been conducted in China. Here, eight new Chinese isolates of AMDV from three provinces in north-east China were analyzed to clarify the molecular epidemiology of AMDV. The seroprevalence of AMDV in north-east China was 41.8% according to counterimmuno-electrophoresis. Genetic variation analysis of the eight isolates showed significant non-synonymous substitutions in the NS1 and VP2 genes, especially in the NS1 gene. All eight isolates included the caspase-recognition sequence NS1:285 (DQTD?S), but not the caspase recognition sequence NS1:227 (INTD?S). The LN1 and LN2 strains had a new 10-amino-acid deletion in-between amino acids 28-37, while the JL3 strain had a one-amino-acid deletion at position 28 in the VP2 protein, compared with the AMDV G strain. Phylogenetic analysis based on most of NS1 (1755 bp) and complete VP2 showed that the AMDV genotypes did not cluster according to their pathogenicity or geographic origin. Local and imported ADMV species are all prevalent in mink farming populations in the north-east of China. This is the first study to report the molecular epidemiology of AMDV in north-east China based on most of NS1 and the complete VP2, and further provides information about polyG deletions and new variations in the amino acid sequences of NS1 and VP2 proteins. This report is a good foundation for further study of AMDV in China. PMID- 29455323 TI - Financial Preparation for Retirement in Brazil: a Cross-Cultural Test of the Interdisciplinary Financial Planning Model. AB - In this investigation, we attempt to replicate the Interdisciplinary Financial Planning Model advanced by Hershey et al. (International Journal of Aging and Human Development, 70, 1-38, 2010) using a sample of Brazilian adults. This model, which was originally tested on individuals from The Netherlands and the United States, posits that psychological, social, and economic forces are key determinants of retirement planning practices and perceptions of saving adequacy. Taken together, fifteen hypotheses were subject to evaluation. Participants were 167 Brazilian working adults, 21-69 years of age, who were married or cohabitating at the time of testing. A path analysis model showed substantial support for the theoretical framework, with all variables found to contribute directly or indirectly to the prediction of financial planning and saving adequacy. Furthermore, two new paths were found to emerge in the Brazilian model that were not observed in the original investigation. This cross-national replication of the Interdisciplinary Financial Planning Model extends research on the topic to a developing country in which relatively few empirical studies of retirement planning have been carried out. Other analyses in the article focus on direct comparisons between the Brazilian model and the models developed based on American and Dutch respondents, with an eye toward better understanding how cultural forces shape the retirement planning process. The discussion focuses on how models of financial planning, such as the Hershey et al. (2010) model, can inform the development of savings-oriented education and intervention programs. PMID- 29455325 TI - Development of a luminescence syncytium induction assay (LuSIA) for easily detecting and quantitatively measuring bovine leukemia virus infection. AB - Bovine leukemia virus (BLV) causes enzootic bovine leukosis and is closely related to the human T cell leukemia virus. Since BLV infection mostly occurs via cell-to-cell transmission, BLV infectivity is generally measured by culturing BLV infected cells with reporter cells that form syncytia upon BLV infection. However, this method is time-consuming and requires skill. To visualize the infectivity of BLV, we developed a new assay called the luminescence syncytium induction assay (LuSIA) that is based on a new reporter cell line designated CC81 BLU3G. CC81-BLU3G is stably transfected with pBLU3-EGFP, which contains the BLV long terminal repeat U3 region linked to the enhanced-green fluorescence protein (EGFP) gene. CC81-BLU3G expresses the EGFP in response to BLV Tax expression specifically, and forms fluorescing syncytia when transfected with an infectious BLV plasmid or when cultured with BLV-infected cells. Compared to the conventional assay, LuSIA was more specific and detected cattle samples with low proviral loads. The fluorescing syncytia was easily detected by eye and automated scanning and LuSIA counts correlated strongly with the proviral load of infected cattle (R2 = 0.8942). PMID- 29455326 TI - New tetrameric forms of the rotavirus NSP4 with antiparallel helices. AB - Rotavirus nonstructural protein 4, the first viral enterotoxin to be identified, is a multidomain, multifunctional glycoprotein. Earlier, we reported a Ca2+-bound coiled-coil tetrameric structure of the diarrhea-inducing region of NSP4 from the rotavirus strains SA11 and I321 and a Ca2+-free pentameric structure from the rotavirus strain ST3, all with a parallel arrangement of alpha-helices. pH was found to determine the oligomeric state: a basic pH favoured a tetramer, whereas an acidic pH favoured a pentamer. Here, we report two novel forms of the coiled coil region of NSP4 from the bovine rotavirus strains MF66 and NCDV. These crystallized at acidic pH, forming antiparallel coiled-coil tetrameric structures without any bound Ca2+ ion. Structural and mutational studies of the coiled-coil regions of NSP4 revealed that the nature of the residue at position 131 (Tyr/His) plays an important role in the observed structural diversity.

AB - Ocular manifestations that occur directly or indirectly as result of a pathologic process that involves other parts of the body, in a pediatric population, will be discussed here. While a myriad number of systemic conditions have ocular manifestations, its importance cannot be undermined because it has implications for both diagnosis and treatment. Often, the eye findings can give a clue to the systemic diagnosis and at other times, not managing the eye manifestations can lead to irreversible blindness although the systemic condition was treated well. So, it is important for all clinicians dealing with pediatric population to be aware of ocular manifestations of the common systemic conditions. The authors discuss the ocular manifestations of the following systemic conditions: Genetic and chromosomal anomalies, phakomatoses, metabolic disorders, infectious diseases, craniofacial anomalies, muscular disorders, inflammatory disorders and miscellaneous.

AB - : The Indian Society for Pediatric and Adolescent Endocrinology has formulated Clinical Practice Guidelines for newborn screening, diagnosis and management of congenital hypothyroidism (CH). This manuscript, part II addresses management and follow-up. RECOMMENDATIONS: Screening should be done for every newborn using cord blood, or postnatal blood ideally at 48 to 72 h of age. Neonates with screen TSH > 20 mIU/L serum units (or >34 mIU/L for samples taken between 24 and 48 h of age) should be recalled for confirmation. For screen TSH > 40 mIU/L, immediate confirmatory venous T4/FT4 and TSH, and for mildly elevated screen TSH, a second screening TSH at 7 to 10 d of age, should be taken. Preterm and low birth weight infants should undergo screening at 48-72 h age. Sick babies should be screened at least by 7 d of age. Venous confirmatory TSH >20 mIU/L before age 2 wk and >10 mIU/L after age 2 wk, with low T4 (<10 MUg/dL) or FT4 (<1.17 ng/dL) indicate primary CH and treatment initiation. Imaging is recommended by radionuclide scintigraphy and ultrasonography after CH is biochemically confirmed but treatment should not be delayed till scans are performed. Levothyroxine is commenced at 10-15 MUg/kg in the neonatal period. Serum T4/FT4 is measured at 2 wk and TSH and T4/FT4 at 1 mo, then 2 monthly till 6 mo, 3 monthly from 6 mo-3 y and every 3-6 mo thereafter. Babies with the possibility of transient CH should be re-evaluated at age 3 y, to assess the need for lifelong therapy. PMID- 29455334 TI - Septicemia from Lactobacillus rhamnosus GG, from a Probiotic Enriched Yogurt, in a Patient with Autologous Stem Cell Transplantation. AB - Probiotic-rich foods are consumed without much restriction. We report here, a case of septic shock caused by yogurt derived Lactobacillus species in a 54-year old male patient with acute promyelocytic leukemia, in second complete remission, and who was an autologous stem cell transplantation recipient. He received high dose chemotherapy and autologous peripheral blood stem cell transplantation. He ingested commercially available probiotic-enriched yogurt because of severe diarrhea. One week later, he developed septic shock, and the pathogen was determined by strain-specific PCR analysis as Lactobacillus rhamnosus GG (ATCC 53103), which was found to be identical with the strain in the yogurt he consumed. Thus, because even low virulent Lactobacilli in the probiotic products can be pathogenic in the compromised hosts, ingestion of such products should be considered with caution in neutropenic patients with severe diarrhea, such as stem cell transplantation recipients. PMID- 29455333 TI - Stress response factors drive regrowth of quiescent cells. AB - Quiescent cells exploit an array of transcription factors to activate stress response machinery and maintain survival under nutrient-limited conditions. Our recent findings reveal that these transcription factors also play an important role in the exit of quiescence and regrowth. By studying Saccharomyces cerevisiae under a continuous, nutrient-limited condition, we found that Msn2 and Msn4 function as master regulators of glycolytic genes in the quiescent-like phase. They control the timing of transition from quiescence to growth by regulating the accumulation rate of acetyl-CoA, a key metabolite that is downstream of glycolysis and drives growth. These findings suggest a model that Msn2/4 not only protect the cells from starvation but also facilitate their regrowth from quiescence. Thus, understanding the functions of stress response transcription factors in metabolic regulation will provide deeper insight into how quiescent cells manage the capacity of regrowth. PMID- 29455335 TI - Evaluating the Safety and Tolerability of Sacubitril/Valsartan for HFrEF Managed Within a Pharmacist Clinic. AB - OBJECTIVE: The objective of this research was to describe the use of pharmacist managed sacubitril/valsartan therapy in a multi-center, outpatient cardiac group. BACKGROUND: Sacubitril/valsartan, an angiotensin receptor-neprilysin inhibitor (ARNi), is a novel agent for the treatment of heart failure. An ARNi is recommended by national guidelines to be used in place of angiotensin-converting enzyme inhibitor (ACEi) or angiotensin receptor blocker (ARB) therapy for patients who remain symptomatic. METHODS: A retrospective chart review was performed to identify patients initiated and fully titrated on sacubitril/valsartan therapy from July 7, 2015 to March 7, 2017. RESULTS: Fifty two of the 72 symptomatic heart failure with reduced ejection fraction (HFrEF) patients prescribed sacubitril/valsartan during the 21-month period were included in this analysis. The average ejection fraction was 26%. The average age was 69 years. At baseline, 26.9% of patients were not on ACEi/ARB therapy and 13.5% were on target-dose therapy. After completing the uptitration process, the maximally tolerated dose of sacubitril/valsartan was 5.8% low-dose, 7.7% mid-dose, and 86.5% target-dose. Loop and thiazide diuretic use decreased significantly. There was a significant mean reduction in systolic blood pressure of 6 mmHg with no significant changes in serum creatinine, blood urea nitrogen, or potassium levels. CONCLUSIONS: With close monitoring and follow-up, ARNi therapy was a safe alternative to ACEi/ARB therapy for chronic symptomatic HFrEF when initiated within a pharmacist clinic. PMID- 29455336 TI - Utilization of organic nitrogen by arbuscular mycorrhizal fungi-is there a specific role for protists and ammonia oxidizers? AB - Arbuscular mycorrhizal (AM) fungi can significantly contribute to plant nitrogen (N) uptake from complex organic sources, most likely in concert with activity of soil saprotrophs and other microbes releasing and transforming the N bound in organic forms. Here, we tested whether AM fungus (Rhizophagus irregularis) extraradical hyphal networks showed any preferences towards certain forms of organic N (chitin of fungal or crustacean origin, DNA, clover biomass, or albumin) administered in spatially discrete patches, and how the presence of AM fungal hyphae affected other microbes. By direct 15N labeling, we also quantified the flux of N to the plants (Andropogon gerardii) through the AM fungal hyphae from fungal chitin and from clover biomass. The AM fungal hyphae colonized patches supplemented with organic N sources significantly more than those receiving only mineral nutrients, organic carbon in form of cellulose, or nothing. Mycorrhizal plants grew 6.4-fold larger and accumulated, on average, 20.3-fold more 15N originating from the labeled organic sources than their nonmycorrhizal counterparts. Whereas the abundance of microbes (bacteria, fungi, or Acanthamoeba sp.) in the different patches was primarily driven by patch quality, we noted a consistent suppression of the microbial abundances by the presence of AM fungal hyphae. This suppression was particularly strong for ammonia oxidizing bacteria. Our results indicate that AM fungi successfully competed with the other microbes for free ammonium ions and suggest an important role for the notoriously understudied soil protists to play in recycling organic N from soil to plants via AM fungal hyphae. PMID- 29455337 TI - Arbuscular mycorrhiza facilitates the accumulation of glycyrrhizin and liquiritin in Glycyrrhiza uralensis under drought stress. AB - Liquorice (Glycyrrhiza uralensis) is an important medicinal plant for which there is a huge market demand. It has been reported that arbuscular mycorrhizal (AM) symbiosis and drought stress can stimulate the accumulation of the active ingredients, glycyrrhizin and liquiritin, in liquorice plants, but the potential interactions of AM symbiosis and drought stress remain largely unknown. In the present work, we investigated mycorrhizal effects on plant growth and accumulation of glycyrrhizin and liquiritin in liquorice plants under different water regimes. The results indicated that AM plants generally exhibited better growth and physiological status including stomatal conductance, photosynthesis rate, and water use efficiency compared with non-AM plants. AM inoculation up regulated the expression of an aquaporin gene PIP and decreased root abscisic acid (ABA) concentrations under drought stress. In general, AM plants displayed lower root carbon (C) and nitrogen (N) concentrations, higher phosphorus (P) concentrations, and therefore, lower C:P and N:P ratios but higher C:N ratio than non-AM plants. On the other hand, AM inoculation increased root glycyrrhizin and liquiritin concentrations, and the mycorrhizal effects were more pronounced under moderate drought stress than under well-watered condition or severe drought stress for glycyrrhizin accumulation. The accumulation of glycyrrhizin and liquiritin in AM plants was consistent with the C:N ratio changes in support of the carbon-nutrient balance hypothesis. Moreover, the glycyrrhizin accumulation was positively correlated with the expression of glycyrrhizin biosynthesis genes SQS1, beta-AS, CYP88D6, and CYP72A154. By contrast, no significant interaction of AM inoculation with water treatment was observed for liquiritin accumulation, while we similarly observed a positive correlation between liquiritin accumulation and the expression of a liquiritin biosynthesis gene CHS. These results suggested that AM inoculation in combination with proper water management potentially could improve glycyrrhizin and liquiritin accumulation in liquorice roots and may be practiced to promote liquorice cultivation. PMID- 29455338 TI - Extracellular ATP is Differentially Metabolized on Papillary Thyroid Carcinoma Cells Surface in Comparison to Normal Cells. AB - The incidence of differentiated thyroid cancer has been increasing. Nevertheless, its molecular mechanisms are not well understood. In recent years, extracellular nucleotides and nucleosides have emerged as important modulators of tumor microenvironment. Extracellular ATP is mainly hydrolyzed by NTPDase1/CD39 and NTPDase2/CD39L1, generating AMP, which is hydrolyzed by ecto-5'-nucleotidase (CD73) to adenosine, a possible promoter of tumor growth and metastasis. There are no studies evaluating the expression and functionality of these ectonucleotidases on normal or tumor-derived thyroid cells. Thus, we investigated the ability of thyroid cancer cells to hydrolyze extracellular ATP generating adenosine, and the expression of ecto-enzymes, as compared to normal cells. We found that normal thyroid derived cells presented a higher ability to hydrolyze ATP and higher mRNA levels for ENTDP1-2, when compared to papillary thyroid carcinoma (PTC) derived cells, which had a higher ability to hydrolyze AMP and expressed CD73 mRNA and protein at higher levels. In addition, adenosine induced an increase in proliferation and migration in PTC derived cells, whose effect was blocked by APCP, a non-hydrolysable ADP analogue, which is an inhibitor of CD73. Taken together, these results showed that thyroid follicular cells have a functional purinergic signaling. The higher expression of CD73 in PTC derived cells might favor the accumulation of extracellular adenosine in the tumor microenvironment, which could promote tumor progression. Therefore, as already shown for other tumors, the purinergic signaling should be considered a potential target for thyroid cancer management and treatment. PMID- 29455339 TI - Analysis of COMT Val158Met polymorphisms and methylation in Chinese male schizophrenia patients with homicidal behavior. AB - Schizophrenia is a severe mental disorder, and its mechanisms have not been fully elucidated. A functional single nucleotide polymorphism (SNP) present in the catechol-O-methyltransferase (COMT) gene, Val158Met (rs4680) (Chr22: 19,963,498), is possibly related to the violent behavior of schizophrenia patients. However, the specific variant that causes violent behavior is still unknown. Since the Val variation of Val158Met (rs4680) introduces a CG site into the sequence, the methylation level of the Val158Met (rs4680) region may also have an association with the homicidal behavior of schizophrenia patients. A case-control study was conducted that included 100 normal males, 100 schizophrenia inpatients, and 100 schizophrenia inpatients with homicidal behavior. A polymorphism of Val158Met (rs4680) and the methylation levels were analyzed by pyrosequencing. Compared to Met carriers, the Val/Val genotype was significantly associated with the homicidal behavior of schizophrenia patients. In addition, the methylation levels of the Val158Met (rs4680) region were significantly different between the three groups. Moreover, the methylation level of an rs4680-related CpG site was significantly associated with the Val/Val genotype which may contribute to the homicidal behavior of schizophrenia patients. In this study, we showed that the Val allele at Val158Met (rs4680) may be associated with the homicidal behavior of schizophrenia patients as well as that the methylation level of Val158Met (rs4680) could be affected by the variation of Val158Met (rs4680) and eventually contribute to the violent behavior of schizophrenia patients. PMID- 29455340 TI - An international clinical study of ability and disability in ADHD using the WHO ICF framework. AB - This is the fourth and final study designed to develop International Classification of Functioning, Disability and Health (ICF, and children and youth version, ICF-CY) core sets for attention-deficit hyperactivity disorder (ADHD). To investigate aspects of functioning and environment of individuals with ADHD as documented by the ICF-CY in clinical practice settings. An international cross sectional multi-centre study was applied, involving nine units from eight countries: Denmark, Germany, India, Italy, Portugal, Saudi Arabia, Sweden and Taiwan. Clinicians and clinical researchers rated the functioning level of 112 children, adolescents and adults with ADHD using the extended ICF-CY checklist version 2.1a. The ratings were based on a variety of information sources, such as medical records, medical history, clinical observations, clinical questionnaires, psychometric tests and structured interviews with participants and family members. In total, 113 ICF-CY categories were identified, of which 50 were related to the activities and participation, 33 to environmental factors and 30 to body functions. The clinical study also yielded strengths related to ADHD, which included temperament and personality functions and recreation and leisure. The study findings endorse the complex nature of ADHD, as evidenced by the many functional and contextual domains impacted in ADHD. ICF-CY based tools can serve as foundation for capturing various functional profiles and environmental facilitators and barriers. The international nature of the ICF-CY makes it possible to develop user-friendly tools that can be applied globally and in multiple settings, ranging from clinical services and policy-making to education and research. PMID- 29455341 TI - Do Callous-Unemotional Traits and Conduct Disorder Symptoms Predict the Onset and Development of Adolescent Substance Use? AB - Despite strong evidence of the relationship between conduct disorder (CD) symptoms and substance use, it is unclear how callous-unemotional (CU) traits predict substance use over and above CD symptoms, and their potential interaction. This study used data from 753 participants followed from grade 7 to 2-years post-high school. Latent growth curve models showed that CU traits predicted the onset of cigarette use, alcohol misuse, and a substance use composite at grade 7 only when no CD symptoms were present. Among those without CD symptoms, boys showed greater change in the odds of using cigarettes, and were more likely to misuse alcohol or use any substance at grade 7 than girls. However, CD symptoms, CU traits, and their interaction did not predict the linear rates of growth of substance use over time. Thus, CU traits may uniquely predict adolescent substance use when CD symptoms are not present. This research has implications for predicting onset of adolescent substance use and for incorporating the assessment of CU traits into interventions targeting adolescent substance use.

AB - The protective effects of chitosan (CS) supplementations on oxidative stress induced by diquat in weaned piglets were investigated. A total of 36 crossbreed piglets with an average live body weight (BW) of 8.80 +/- 0.53 kg were weaned at 28 +/- 2 days and randomly divided into six dietary treatments (n = 6): control (basal diet), negative control (10 mg diquat/kg BW injected to piglets fed with basal diet), and basal diet treatments containing either 250, 500, 1000, or 2000 mg/kg of CS administered to piglets injected with 10 mg diquat/kg BW. The experiment conducted for 21 days which consisted of pre-starter period (14 days) and starter period (7 days). BW, feed intake, and fecal consistency were monitored. Blood samples were collected to determine antioxidative and immune parameters. CS supplementation improved the growth performance and decreased fecal score of piglets from days 1 to 14. Diquat also induced oxidative stress and inflammatory responses by decreasing the activities of antioxidant and regulating cytokines. But dietary CS alleviated these negative effects induced by diquat that showed decreasing serum concentrations of pro-inflammatory cytokines but increasing activities of antioxidant enzymes and anti-inflammatory cytokines. Results indicated that CS attenuated the oxidative stress of piglets caused by diquat injection. PMID- 29455343 TI - The first isolation of Westerdykella dispersa in a critically burned patient. AB - Patients with critical thermal trauma belong to one of the most high-risk groups for development of infectious complications. Fungal infections are not among frequent complications during therapy of patients with thermal trauma, yet their incidence dramatically aggravates the prognosis for patients with this disorder. In the case report, we present the case of a young man with a critical burn, where Westerdykella dispersa was isolated. Identification of the pathogen was provided with a combination of cultivation and molecular biological confirmation. In this case, the distinction between infection and colonization was very complicated. Histopathological examination for definitive diagnosis of infection was not performed because the material from unburned soft tissue sampling could further compromise the function of the hand. Repeated cultivation and molecular identification W. dispersa before and after the necrectomy is indicative of infection rather than colonization. It is the second documented case of positive cultivation with this pathogen in humans and the first such case in a non neutropenic host.

The lateral pharyngeal space contains important structures such as the internal carotid artery and close proximity with the cranium basis. The aim of this paper is to report a clinical case of a lower third molar displaced to the lateral pharyngeal space after a mandibular angle fracture and its treatment by surgical intervention. The tooth was removed under general anesthesia by direct approach and the fracture was reduced and fixed with a plate and screws. This case report illustrates the importance of an immediate procedure to avoiding severe complications and further damage to important anatomical structures.

AB - BACKGROUND AND PURPOSE: Chinese orthopaedic surgeons have made a substantial contribution to the development of orthopaedics worldwide, and traditional Chinese medicine (TCM) in orthopaedics has a very long history in China. We make a brief review of the development of orthopaedics in China, intending to pave the way for further understanding of Chinese orthopaedics for scholars all over the world. RESULTS: The description of fractures firstly appeared in 3600 years ago in China, and the theories, experience, and treatment strategies of TCM still play important roles in clinical diagnosis and treatment of orthopaedic disorders in our country. Western orthopaedics was first introduced into China in the early twentieth century. After decades of development, Chinese scholars have made some gratifying achievements in orthopaedics. CONCLUSIONS: Orthopaedics is constantly evolving, and we need to strengthen the ability of independent innovation to achieve orthopaedic surgeons' Chinese dream, and better serve our patients.

AB - INTRODUCTION: Both hip resurfacing arthroplasty (HRA) and large-diameter head metal-on-metal total hip arthroplasty (LDH MoM THA) are generally used for young and active patients. A number of comparative studies of HRA and total hip arthroplasty have been published in the literature. However, studies that have compared HRA with LDH MoM THA are rare. The purpose of this study is to compare the mid-term results of HRA with those of LDH MoM THA in young patients. PATIENTS AND METHODS: Between 2007 and 2011, 68 patients were enrolled in the study and randomized into two groups: HRA group (28 hips) and LDH MoM THA group (40 hips). Peri-operative data including blood loss, surgery duration, size of the implant, and post-operative complications were recorded. All patients were assessed clinically and radiologically at six weeks; one, three and five years; and at the time of final review. Functional outcome were assessed using Harris hip (HHS), University of California Los Angeles (UCLA) and Oxford hip (OHS) scores. The mean follow-up for all patients was 7.4 years (5 to 9). RESULTS: Patient groups matched similarly in age, percent female, body mass index, preoperative HHS, and follow-up time. No differences were observed between the two groups in blood loss or in head size or acetabular inclination angle. HRA group had significantly longer surgery duration but less blood loss. The two groups had comparable HHS, UCLA, and OHS at the latest follow-up. Major complications, such as fracture, dislocation, infection, and adverse reactions to the metal debris (ARMD) were not found in the two groups. Only one case in LDH MoM THA group underwent revision surgery due to unexplained pain. CONCLUSION: Comparison of HRA and LDH MoM THA shows similar mid-term clinical results. HRA may be preferable due to the well preserved bone stock and restoration of the native anatomy. LDH MoM THA may be used with caution due to the excessive metal ion release.

AB - PURPOSE: The location of the necrotic lesion is one of the important factors for collapse in osteonecrosis of the femoral head (ONFH). The significance of anterior localization has been little studied. This study evaluated the effects of anterior boundary of a necrotic lesion on collapse. METHODS: We reviewed the outcomes of 113 consecutive non-collapsed asymptomatic hips in 98 ONFH patients with mean follow-up of 4.7 years (2.0-11.8) after the initial magnetic resonance (MR) imaging. The presence or absence of collapse was investigated using follow up radiographs. The location of the anterior boundary of a necrotic lesion was assessed using the anterior necrotic angle between the midline of the femoral neck shaft and the line passing from the femoral head centre to the anterior boundary on mid-oblique MR imaging. Multivariate analysis was performed to identify risk factors for collapse, and further analyses were executed according to the lateral boundary of the necrotic lesion. RESULTS: During the follow-up period, collapse was confirmed in 61 hips (54.0%). Multivariate analysis revealed that the anterior necrotic angle was independently associated with collapse as well as the lateral boundary of the necrotic lesion. When the lateral boundary was located at the middle third of weight-bearing portion (32 hips), that was generally categorized as a low risk of collapse, all five cases with anterior necrotic angle >= 79 degrees developed collapse, whereas only one of 27 cases (3.7%) with an anterior necrotic angle < 79 degrees developed collapse (p < 0.0001). CONCLUSIONS: This study indicates that ONFH patients with anterior localization of a necrotic lesion can develop collapse even if the necrotic lesion is medially located.

AB - In the present study, long-term environmental impacts of compact and ground cement composites, in which 30 wt.% of cement was replaced by washed municipal solid wastes incineration (MSWI) fly ash, were investigated for use in building industry. Consecutive leaching tests over a time span of 180 days were performed in acid water, deionized water, and saline water, respectively, with the accumulative concentration of different elements determined in the leachate. Different leaching behaviors are observed among different potential toxic elements (PTEs). For instance, higher concentrations of V in the leachate were observed from the compact cement composites than those from the ground ones. The concentration of Ba in the leachate increased with the decrease of particle size of the cement composites, and an initial increase in the leaching efficiency of Sn was followed by a clear decline with the leaching time. In addition, kinetic study revealed that the leaching behaviors of potential toxic elements follow a second-order model. The results demonstrated that the addition of washed MSWI fly ash into cement can contribute to the attrition resistance, indicating that the washed MSWI fly ash could be a promising alternative for cement as supplementary building materials. PMID- 29455350 TI - Analysing the accuracy of machine learning techniques to develop an integrated influent time series model: case study of a sewage treatment plant, Malaysia. AB - The function of a sewage treatment plant is to treat the sewage to acceptable standards before being discharged into the receiving waters. To design and operate such plants, it is necessary to measure and predict the influent flow rate. In this research, the influent flow rate of a sewage treatment plant (STP) was modelled and predicted by autoregressive integrated moving average (ARIMA), nonlinear autoregressive network (NAR) and support vector machine (SVM) regression time series algorithms. To evaluate the models' accuracy, the root mean square error (RMSE) and coefficient of determination (R2) were calculated as initial assessment measures, while relative error (RE), peak flow criterion (PFC) and low flow criterion (LFC) were calculated as final evaluation measures to demonstrate the detailed accuracy of the selected models. An integrated model was developed based on the individual models' prediction ability for low, average and peak flow. An initial assessment of the results showed that the ARIMA model was the least accurate and the NAR model was the most accurate. The RE results also prove that the SVM model's frequency of errors above 10% or below - 10% was greater than the NAR model's. The influent was also forecasted up to 44 weeks ahead by both models. The graphical results indicate that the NAR model made better predictions than the SVM model. The final evaluation of NAR and SVM demonstrated that SVM made better predictions at peak flow and NAR fit well for low and average inflow ranges. The integrated model developed includes the NAR model for low and average influent and the SVM model for peak inflow.

AB - Soil contamination by persistent organic pollutants (POPs) poses a great threat to historically polluted soil worldwide. In this study, soils were characterized, and organochlorine pesticides contained in the soils were identified and quantified. Individual electrokinetic (IE), EK-Fenton-coupled technologies (EF), and enhanced EK-Fenton treatment (E-1, E-2, and E-3) were applied to remediate soils contaminated with hexachloro-cyclohexane soprocide (HCH) and dichloro diphenyl-trichloroethane (DDT). Variation of pH, electrical conductivity, and electroosmotic flow was evaluated during the EK-Fenton process. The IE treatment showed low removal efficiency for HCHs (30.5%) and DDTs (25.9%). In the EF treatment, the highest removal level (60.9%) was obtained for alpha-HCH, whereas P,P-DDT was the lowest (40.0%). Low solubility of pollutants impeded the HCH and DDT removal. After enhanced EK-Fenton treatment, final removal of pollutants decreased as follows: beta-HCH (82.6%) > gamma-HCH (81.6%) > alpha-HCH (81.2%) > delta-HCH (80.0%) > P,P-DDD (73.8%) > P,P-DDE (73.1%) > P,P-DDT (72.6%) > O,P-DDT (71.5%). The results demonstrate that EK-Fenton is a promising technology for POP removal in historically polluted soil. PMID- 29455351 TI - Lead facilitates foci formation in a Balb/c-3T3 two-step cell transformation model: role of Ape1 function. AB - Several possible mechanisms have been examined to gain an understanding on the carcinogenic properties of lead, which include among others, mitogenesis, alteration of gene expression, oxidative damage, and inhibition of DNA repair. The aim of the present study was to explore if low concentrations of lead, relevant for human exposure, interfere with Ape1 function, a base excision repair enzyme, and its role in cell transformation in Balb/c-3T3. Lead acetate 5 and 30 MUM induced APE1 mRNA and upregulation of protein expression. This increase in mRNA expression is consistent throughout the chronic exposure. Additionally, we also found an impaired function of Ape1 through molecular beacon-based assay. To evaluate the impact of lead on foci formation, a Balb/c-3T3 two-step transformation model was used. Balb/c-3T3 cells were pretreated 1 week with low concentrations of lead before induction of transformation with n-methyl-n nitrosoguanidine (MNNG) (0.5 MUg/mL) and 12-O-tetradecanoylphorbol-13-acetate (TPA) (0.1 MUg/mL) (a classical two-step protocol). Morphological cell transformation increased in response to lead pretreatment that was paralleled with an increase in Ape1 mRNA and protein overexpression and an impairment of Ape1 activity and correlating with foci number. In addition, we found that lead pretreatment and MNNG (transformation initiator) increased DNA damage, determined by comet assay. Our data suggest that low lead concentrations (5, 30 MUM) could play a facilitating role in cellular transformation, probably through the impaired function of housekeeping genes such as Ape1, leading to DNA damage accumulation and chromosomal instability, one of the most important hallmarks of cancer induced by chronic exposures. PMID- 29455353 TI - Lethal and sub-lethal effects of cyproconazole on freshwater organisms: a case study with Chironomus riparius and Dugesia tigrina. AB - The fungicide cyproconazole (CPZ) inhibits the biosynthesis of ergosterol, an essential sterol component in fungal cell membrane and can also affect non-target organisms by its inhibitory effects on P450 monooxygenases. The predicted environmental concentration of CPZ is up to 49.05 MUg/L and 145.89 MUg/kg in surface waters and sediments, respectively, and information about CPZ toxicity towards non-target aquatic organisms is still limited. This study aimed to address the lack of ecotoxicological data for CPZ, and thus, an evaluation of the lethal and sub-lethal effects of CPZ was performed using two freshwater invertebrates (the midge Chironomus riparius and the planarian Dugesia tigrina). The estimated CPZ 48 h LC50 (95% CI) was 17.46 mg/L for C. riparius and 47.38 mg/L for D. tigrina. The emergence time (EmT50) of C. riparius was delayed by CPZ exposure from 0.76 mg/L. On the other hand, planarians showed higher tolerance to CPZ exposure. Sub-lethal effects of CPZ on planarians included reductions in locomotion (1.8 mg/L), delayed photoreceptors regeneration (from 0.45 mg/L), and feeding inhibition (5.6 mg/L). Our results confirm the moderate toxicity of CPZ towards aquatic invertebrates but sub-lethal effects observed also suggest potential chronic effects of CPZ with consequences for population dynamics. PMID- 29455354 TI - Uptake and elimination kinetics of trifluralin and pendimethalin in Pheretima spp. and Eisenia spp. AB - The purpose of this study was to clarify the kinetic bioaccumulation potential of herbicides in the earthworm, Pheretima spp., the most common earthworms throughout Asia, and Eisenia spp., litter-feeding earthworms included in the test species recommended by the Organization for Economic Co-operation and Development. The kinetic bioaccumulation factors of trifluralin and pendimethalin were estimated from an uptake test for 10 or 12 days and from an elimination test for 10 days. The time required to reach a steady state following herbicide exposure was 7 days for both herbicides in Eisenia spp. and 1 day in Pheretima spp. The uptake rate constant (g-soil/g-worm/day) and elimination rate constant (per day) for trifluralin were 2.1 and 0.23 in Eisenia spp. and 0.42 and 0.45 in Pheretima spp., respectively, and those for pendimethalin were 1.5 and 0.26 in Eisenia spp. and 0.27 and 1.0 in Pheretima spp., respectively. Kinetic bioaccumulation factors of both herbicides were relatively close to bioaccumulation factors in steady state and were higher in Eisenia spp. (8.9 for trifluralin and 5.7 for pendimethalin) than in Pheretima spp. (0.95 and 0.26). These results demonstrated that the herbicide bioaccumulation risk is lower for Pheretima spp. than for Eisenia spp. because of the lower uptake rate and higher elimination rate in Pheretima spp. PMID- 29455355 TI - The combination of Luffa cylindrical fibers and metal oxides offers a highly performing hybrid fiber material in water decontamination. AB - The present investigation aims to prepare a hybrid material from Luffa cylindrica and metal oxides (ZnO, Al2O3) by precipitation for different percentages of zinc and aluminum (1, 2, and 4%) with a determined amount of biomass (a diameter of 250 MUm). Physicochemical characterization of "Luffa cylindrica" and "Luffa cylindrica-metal oxides" was carried out by Boehm titration, pHPZC determination, scanning electron microscopy (SEM), and FTIR spectroscopic analysis. The process was optimized according to the adsorbed amount of methylene blue: MB (cationic dye) and methyl orange: MO (anionic dye) onto Luffa cylindrica and hybrid materials prepared. The results demonstrated the efficiency of the designed hybrid materials in removing MB and MO, accelerating the biosorption process and improving the performance of Luffa cylindrica fibers. The highest quantities adsorbed of dyes were obtained by the hybrid material prepared using 4% ZnO. Finally, the Brouers-Sotolongo mathematical modeling of kinetics was used in order to describe the pollutants retention process. PMID- 29455356 TI - A novel electrocatalytic approach for effective degradation of Rh-B in water using carbon nanotubes and agarose. AB - Carbon nanotubes (CNTs)/agarose (AG) membrane on the ITO (indium tin oxide) conductive glass, with high efficiency of electrocatalytic degradation for rhodamine B (Rh-B) in water, was prepared using an easy and green method. The prepared CNTs/AG membrane was characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), energy dispersive spectra (EDS), infrared spectroscopy (IR), and electrochemical impedance spectroscopy (EIS). The results revealed that CNTs were dispersed in the AG membrane. Additionally, the electrocatalytic activities for Rh-B were conducted on the electrochemical workstation with a three-electrode system. Both initial pH and potential played an important role in the process of electrocatalytic degradation. At pH 3 and potential reaching 4 V, the removal rate of Rh-B (10 mg/L) in water achieved 96% within 20 min. The stability of the prepared CNTs/AG membrane was also investigated. Besides, the toxicities of the main intermediates from the electrocatalytic degradation for Rh-B were calculated using the ECOSAR program and EPIWIN software, and results indicated that the toxicities of some intermediates were higher than those of the parent pollutant (Rh-B). These findings provided a light-spot to simplify the preparation of efficient working electrode and emphasized the possible potential risks from intermediates at the same time. PMID- 29455357 TI - Phytochemical constituents, antioxidant activity, and antiproliferative properties of black, red, and brown rice bran. AB - BACKGROUND: In the recent years, the health benefits of the pigmented rice varieties have reported due to the presence of bioactive compounds. In this study, the phytochemical constituents (total phenolic, flavonoid and anthocyanin content) and individual phenolics and flavonoids of the extracts of sixteen genotypes of pigmented rice bran were evaluated using spectrophotometric and ultra-high performance liquid chromatography method. Antioxidative properties of the free and bound fractions were evaluated using nitric oxide and 1,1-diphenyl-2 picrylhydrazyl scavenging assays. Extracts were evaluated for antiproliferative activity against breast cancer cell lines (MCF-7 and MDA-MB-231) using the MTT assay. RESULTS: Signifficant diferences were observed in the concentrations of phytochemicals and biological activities among different pigmented rice brans. The highest phytochemical content was observed in black rice bran followed by red and brown rice bran. The concentration of free individual flavonoids and phenolic compounds were significantly higher than those of bound compounds except those of ferulic acid and p-coumaric acid. Highest antioxidant activities were observed in black rice bran, followed by red and brown rice bran extracts. Extracts of black rice bran exhibited potent antiproliferative activity, with half maximal inhibitory concentrations (IC50) of 148.6 and 119.2 mg/mL against MCF-7 and MDA MB-231 cell lines, respectively, compared to the activity of the extracts of red rice bran (175.0 and 151.0 mg/mL, respectively) and brown rice bran (382.3 and 346.1 mg/mL, respectively). CONCLUSIONS: Black rice bran contains high levels of phytochemicals, and thus has potent pharmaceutical activity. This highlights opportunities for researcher to breed new genotypes of rice with higher nutritional values, which the food industry can use to develop new products that will compete in expanding functional food markets.

AB - Waste management involves various procedures and resources for proper handling of waste materials in compliance with health codes and environmental regulations. Landfills are one of the oldest, most convenient, and cheapest methods to deposit waste. However, landfill utilization involves social, environmental, geotechnical, cost, and restrictive regulation considerations. For instance, landfills are considered a source of hazardous air pollutants that can cause health and environmental problems related to landfill gas and non-methanic organic compounds. The increasing number of sensors and availability of remotely sensed images along with rapid development of spatial technology are helping with effective landfill site selection. The present study used fuzzy membership and the analytical hierarchy process (AHP) in a geo-spatial environment for landfill site selection in the city of Sharjah, United Arab Emirates. Macro- and micro level factors were considered; the macro-level contained social and economic factors, while the micro-level accounted for geo-environmental factors. The weighted spatial layers were combined to generate landfill suitability and overall suitability index maps. Sensitivity analysis was then carried out to rectify initial theoretical weights. The results showed that 30.25% of the study area had a high suitability index for landfill sites in the Sharjah, and the most suitable site was selected based on weighted factors. The developed fuzzy-AHP methodology can be applied in neighboring regions with similar geo-natural conditions. PMID- 29455359 TI - Eosinophilic Esophagitis: an Important Comorbid Condition of Asthma? AB - Eosinophilic esophagitis and asthma are frequently found as comorbid conditions in children and adults along with other manifestations of atopic diathesis. These two conditions have similar T helper 2 responses-driven pathophysiology and share common management strategies such as using systemic corticosteroids and targeted anti-cytokine biologic therapies. Review of the literature finds that asthma is often a comorbid condition in eosinophilic esophagitis in both children and adults; however, the EoE-asthma relationship remains poorly characterized mechanistically and clinically. EoE and asthma commonly share several comorbid conditions such as allergic rhinitis and gastroesophageal reflux disease; therefore, addressing these comorbid conditions has the potential to improve and/or maintain control in both diseases. Similar to asthma, patients with EoE frequently demonstrate elevations in serum markers of atopy, including serum IgE levels, peripheral eosinophil counts, and T helper 2-related cytokines. Gastroesophageal reflux disease is thought to affect asthma through microaspirations, airway hyperresponsiveness, and increased vagal tone. The understanding of the relationship between gastroesophageal reflux and EoE is still evolving but seems to be bidirectional and interactive. In terms of treatment, similar classes of medications have been used in both EoE and asthma. In both children and adults, EoE remission can be achieved by food trigger avoidance and use of corticosteroids and biologic therapies. Asthma control is mostly achieved through inhaled corticosteroids, and long but biologic therapies are increasingly used in severe subsets of the disease. Significant clinical and mechanistic work needs to be accomplished to better understand the relationship between asthma, EoE, and their interaction with other allergic diseases. Understanding whether shared mechanisms exist can lead to the development of new diagnostic and therapeutic strategies. The following review examines the existing literature regarding prevalence, common comorbidities, and potential therapeutic approach and identifies gaps in knowledge and future directions. PMID- 29455358 TI - The Use of Biomarkers to Predict Aero-Allergen and Food Immunotherapy Responses. AB - The incidence of allergic conditions has continued to rise over the past several decades, with a growing body of research dedicated toward the treatment of such conditions. By driving a complex range of changes in the underlying immune response, immunotherapy is the only therapy that modulates the immune system with long-term effects and is presently utilized for the treatment of several atopic conditions. Recent efforts have focused on identifying biomarkers associated with these changes that may be of use in predicting patients with the highest likelihood of positive clinical outcomes during allergen immunotherapy (AIT), providing guidance regarding AIT discontinuation, and predicting symptomatic relapse and the need for booster AIT after therapy. The identification of such biomarkers in food allergy has the additional benefit of replacing oral food challenges, which are presently the gold standard for diagnosing food allergies. While several markers have shown early promise, research has yet to identify a marker that can invariably predict clinical response to AIT. Skin prick testing (SPT) and specific IgE have commonly been used as inclusion criteria for the initiation of AIT and prediction of reactions during subsequent allergen challenge; however, existing data suggests that changes in these markers are not always associated with clinical improvement and can be widely variable, reducing their utility in predicting clinical response. Similar findings have been described for the use of allergen-specific functional IgG4 antibodies, basophil activation and histamine release, and type 2 innate lymphoid cells. There appears to be a promising association between changes in the expression of dendritic cell associated markers, as well as the use of DNA promoter region methylation patterns in the prediction of allergy status following therapy. The cellular and molecular changes brought about by immunotherapy are still under investigation, but major strides in our understanding are being made. PMID- 29455362 TI - Predicting functional outcomes of posterior circulation acute ischemic stroke in first 36 h of stroke onset. AB - Posterior circulation acute ischemic stroke constitutes one-fourth of all ischemic strokes and can be efficiently quantified using the posterior circulation Alberta stroke program early computed tomography score (PC-ASPECTS) through diffusion-weighted imaging. We investigated whether the PC-ASPECTS and National Institutes of Health Stroke Scale (NIHSS) facilitate functional outcome prediction among Chinese patients with posterior circulation acute ischemic stroke. Participants were selected from our prospective stroke registry from January 1, 2015, to December 31, 2016. The baseline NIHSS score was assessed on the first day of admission, and brain magnetic resonance imaging was performed within 36 h after stroke onset. Simple and multiple logistic regressions were conducted to determine stroke risk factors and the PC-ASPECTS. Receiver operating characteristics (ROC) curve analysis was performed to compare the NIHSS and PC ASPECTS. Of 549 patients from our prospective stroke admission registry database, 125 (22.8%) had a diagnosis of posterior circulation acute ischemic stroke. The optimal cutoff for the PC-ASPECTS in predicting outcomes was 7. The odds ratios of the PC-ASPECTS (<= 7 vs > 7) in predicting outcomes were 6.33 (p = 0.0002) and 8.49 (p = 0.0060) in the univariate and multivariate models, respectively, and 7.52 (p = 0.0041) in the aging group. On ROC curve analysis, the PC-ASPECTS demonstrated more reliability than the baseline NIHSS for predicting functional outcomes of minor posterior circulation stroke. In conclusion, both the PC ASPECTS and NIHSS help clinicians predict functional outcomes. PC-ASPECTS > 7 is a helpful discriminator for achieving favorable functional outcome prediction in posterior circulation acute ischemic stroke. PMID- 29455361 TI - Treatment of neuromyelitis optica with rituximab: a 2-year prospective multicenter study. AB - OBJECTIVE: Neuromyelitis optica (NMO) is a very severe autoimmune disorder of the central nervous system. It affects young subjects and has a poor prognosis both on a functional and vital level. Therefore, it is imperative to reduce the frequency of relapses. The purpose of this study was to evaluate the clinical and neuroradiological effectiveness of rituximab (RTX) on active forms of NMO. METHODS: We conducted a 2-year open prospective multicenter study that included 32 patients treated with RTX at a dose of 375 mg/m2/week for 1 month. When the number of circulating CD19+ B cells reached 1%, a maintenance therapy was started, consisting of two infusions of 1 g of RTX, administered at a 15-day interval. The primary objective was to reduce the annual relapse rate (ARR), in comparison to that observed in the 2 years before treatment onset. RESULTS: Rituximab administration reduced the ARR from 1.34 to 0.56 (p = 0.0005). The average Expanded Disability Status Scale (EDSS) score significantly improved by 1.1 point, from 5.9 (2-9) to 4.8 (0-9) after 2 years (p = 0.03). Anti-aquaporin-4 antibodies' level predicted treatment failure (p = 0.03). Frequency of Gad+ lesions in spinal cord decreased from 23.3 to 14.2%. RTX treatment did not prevent the death of three patients (treatment failure in two patients and acute myeloid leukemia in a patient previously treated with mitoxantrone). CONCLUSION: Rituximab is clinically effective in active forms of NMO, although few patients are resistant to the treatment. PMID- 29455363 TI - Predicting Autism Spectrum Disorder Using Domain-Adaptive Cross-Site Evaluation. AB - The advances in neuroimaging methods reveal that resting-state functional fMRI (rs-fMRI) connectivity measures can be potential diagnostic biomarkers for autism spectrum disorder (ASD). Recent data sharing projects help us replicating the robustness of these biomarkers in different acquisition conditions or preprocessing steps across larger numbers of individuals or sites. It is necessary to validate the previous results by using data from multiple sites by diminishing the site variations. We investigated partial least square regression (PLS), a domain adaptive method to adjust the effects of multicenter acquisition. A sparse Multivariate Pattern Analysis (MVVPA) framework in a leave one site out cross validation (LOSOCV) setting has been proposed to discriminate ASD from healthy controls using data from six sites in the Autism Brain Imaging Data Exchange (ABIDE). Classification features were obtained using 42 bilateral Brodmann areas without presupposing any prior hypothesis. Our results showed that using PLS, SVM showed poorer accuracies with highest accuracy achieved (62%) than without PLS but not significantly. The regions occurred in two or more informative connections are Dorsolateral Prefrontal Cortex, Somatosensory Association Cortex, Primary Auditory Cortex, Inferior Temporal Gyrus and Temporopolar area. These interrupted regions are involved in executive function, speech, visual perception, sense and language which are associated with ASD. Our findings may support early clinical diagnosis or risk determination by identifying neurobiological markers to distinguish between ASD and healthy controls. PMID- 29455364 TI - Hyperirisinemia is independently associated with subclinical hypothyroidism: correlations with cardiometabolic biomarkers and risk factors. AB - PURPOSE: Irisin, a newly discovered adipo-myokine, is implicated in the modulation of the adipose phenotype, increasing energy expenditure and ameliorating systemic metabolism. Our aim was to investigate circulating irisin in subclinical hypothyroidism (SH) and study its associations with cardiometabolic risk factors. METHODS: In a large case-control study, serum irisin, insulin resistance and lipid parameters, classic adipokines, inflammatory and hepatic biomarkers, and cardiovascular risk factors were determined in 120 consecutive patients with SH and 120 healthy controls matched on age, gender, and date of blood draw. Sixteen patients with SH received L-T4 treatment and, after 6 months, serum irisin and other biomarkers were assessed. RESULTS: SH cases exhibited significantly higher circulating irisin than controls (p < 0.001). In all participants, irisin was positively associated with TSH, anti-TG, HOMA-IR, C peptide, lipid and inflammatory biomarkers, leptin, and cardiovascular risk factors, including Framigham score and apolipoprotein B/apolipoprotein A-I. Irisin was negatively correlated with adiponectin, HDL-C, and thyroid hormones. Serum irisin was independently associated with SH, above and beyond body mass index and cardiometabolic factors (p = 0.02). TSH was an independent predictor of circulating irisin (p = 0.003). L-T4 therapy did not reverse considerably the hyperirisinemic status in treated SH patients (p = 0.09). CONCLUSIONS: Irisin may represent an adipo-myokine counterbalancing a potential, gradual deterioration of lipid metabolism and insulin sensitivity in SH as well as reflecting a protective compensatory mechanism against oxidative muscle and thyroid cell stress. More mechanistic and prospective studies shedding light on the pathogenetic role of irisin in SH are needed to confirm and extend these data. PMID- 29455365 TI - Gender-differences in glycemic control and diabetes related factors in young adults with type 1 diabetes: results from the METRO study. AB - PURPOSE: To describe gender differences concerning glycemic control, cardiovascular risk factors, diabetic complications, concomitant pathologies, and circulating endothelial progenitor cells (EPCs), in a population of young adults with type 1 diabetes. METHODS: We collected data from 300 consecutively patients (168 males and 132 females), aged 18-30 years, among those admitted at Diabetes Unit of University of Campania "Luigi Vanvitelli" (Naples, Italy) from March 2012 to January 2017. Circulating levels of seven EPCs phenotypes were determined by flow cytometry. RESULTS: As compared to men, women with type 1 diabetes had a significantly higher HbA1c levels (%, 8.4 +/- 1.3 vs. 8.1 +/- 1.3, P = 0.020), body mass index (Kg/m2, 24.8 +/- 4.2 vs. 23.9 +/- 3.9, P = 0.034), HDL cholesterol (mg/dL, 61.7 +/- 13.7 vs. 54.7 +/- 13.9, P < 0.001), and a lower count of both CD133+KDR+ and CD34+KDR+CD133+ EPCs (P = 0.022, P < 0.001, respectively). A higher proportion of women had overweight/obesity, and thyroiditis; smoking and sexual dysfunctions were more prevalent in men than in women. CONCLUSIONS: Young adults with type 1 diabetes present gender differences with regard to glycemic control, prevalence of some cardiovascular risk factors, sexual dysfunctions and circulating levels of EPCs, most often to the detriment of women. PMID- 29455366 TI - Phospholipase Ddelta assists to cortical microtubule recovery after salt stress. AB - The dynamic microtubule cytoskeleton plays fundamental roles in the growth and development of plants including regulation of their responses to environmental stress. Plants exposed to hyper-osmotic stress commonly acclimate, acquiring tolerance to variable stress levels. The underlying cellular mechanisms are largely unknown. Here, we show, for the first time, by in vivo imaging approach that linear patterns of phospholipase Ddelta match the localization of microtubules in various biological systems, validating previously predicted connection between phospholipase Ddelta and microtubules. Both the microtubule and linear phospholipase Ddelta structures were disintegrated in a few minutes after treatment with oryzalin or salt. Moreover, by using immunofluorescence confocal microscopy of the cells in the root elongation zone of Arabidopsis, we have shown that the cortical microtubules rapidly depolymerized within 30 min of treatment with 150 or 200 mM NaCl. Within 5 h of treatment, the density of microtubule arrays was partially restored. A T-DNA insertional mutant lacking phospholipase Ddelta showed poor recovery of microtubule arrays following salt exposition. The restoration of microtubules was significantly retarded as well as the rate of root growth, but roots of overexpressor GFP-PLDdelta prepared in our lab, have grown slightly better compared to wild-type plants. Our results indicate that phospholipase Ddelta is involved in salt stress tolerance, possibly by direct anchoring and stabilization of de novo emerging microtubules to the plasma membrane, providing novel insight into common molecular mechanism during various stress events.

AB - Living with congenital heart disease (CHD) presents survivors with numerous stressors, which may contribute to emotional problems. This study examined (a) whether coping with CHD-related stress predicts symptoms of depression and anxiety, and (b) whether associations between coping and emotional distress are moderated by involuntary stress reactivity. Adolescents and young adults diagnosed with CHD (Mage = 26.4) were recruited from pediatric and adult outpatient cardiology clinics. Participants (N = 168) completed online self report measures. Hierarchical multiple regression analyses revealed that secondary control coping (e.g., cognitive restructuring, positive thinking) predicted lower depression and anxiety. Primary control coping (e.g., problem solving) and stress reactivity (e.g., rumination, emotional numbing) interacted to predict depression and anxiety: the higher individuals were in involuntary stress reactivity, the stronger was the association between primary control coping and lower depression and anxiety. These results can inform clinical efforts to prevent or reduce emotional distress among CHD survivors.

AB - : Significant overtreatment with antibiotics for suspected early onset sepsis (EOS) constitutes a persisting clinical problem, generating unnecessary risks, harms, and costs for many newborns. We aimed to study feasibility and impact of a sepsis calculator to help guide antibiotic for suspected EOS in a European setting. In this single-center study, the sepsis calculator was implemented as an addition to and in accordance with existing protocols. One thousand eight hundred seventy-seven newborns >= 35 weeks of gestational age were prospectively evaluated; an analogous retrospective control group (n = 2076) was used for impact analysis. We found that empirical treatment with intravenous antibiotics for suspected EOS was reduced from 4.8 to 2.7% after sepsis calculator implementation (relative risk reduction 44% (95% confidence interval 21.4 59.5%)). No evidence for changes in time to treatment start, treatment duration, or proven sepsis rates was found. Adherence to sepsis calculator recommendation was 91%. CONCLUSION: Pragmatic and feasible implementation of the sepsis calculator yields a 44% reduction of empirical use of antibiotics for EOS, without signs of delay or prolongation of treatment. These findings warrant a multicenter, nation-wide, randomized study evaluating systematic use of the sepsis calculator prediction model and its effects in clinical practice outside of the USA. What is known: * Significant overtreatment with antibiotics for suspected early-onset sepsis results in unnecessary costs, risks, and harms. * Implementation of the sepsis calculator in the USA has resulted in a significant decrease in empirical antibiotic treatment, without apparent adverse events. What is new: * Implementation of the sepsis calculator in daily clinical decision making in a Dutch teaching hospital is feasible in conjunction with existing protocols, with high adherence. * Antibiotic therapy for suspected early-onset sepsis was reduced by 44% following implementation of the calculator.

AB - Among spinal tumors that occur intradurally, meningiomas, nerve sheath tumors, ependymomas, and astrocytomas are the most common. While a spinal MRI is the state of the art to diagnose intradural spinal tumors, in some cases CT scans, angiography, CSF analyses, and neurophysiological examination can be valuable. The management of these lesions depends not only on the histopathological diagnosis but also on the clinical presentation and the anatomical location, allowing either radical resection as with most extramedullary lesions or less invasive strategies as with intramedullary lesions. Although intramedullary lesions are rare and sometimes difficult to manage, well-planned treatment can achieve excellent outcome without treatment-related deficits. Technical advances in imaging, neuromonitoring, minimally invasive approaches, and radiotherapy have improved the outcome of intradural spinal tumors. However, the outcome in malignant intramedullary tumors remains poor. While surgery is the mainstay treatment for many of these lesions, radiation and chemotherapy are of growing importance in recurrent and multilocular disease. We reviewed the literature on this topic to provide an overview of spinal cord tumors, treatment strategies, and outcomes. Typical cases of extra- and intramedullary tumors are presented to illustrate management options and outcomes. PMID- 29455370 TI - Incomplete copolymer degradation of in situ chemotherapy. AB - In situ carmustine wafers containing 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU) are commonly used for the treatment of recurrent glioblastoma to overcome the brain-blood barrier. In theory, this chemotherapy diffuses into the adjacent parenchyma and the excipient degrades in maximum 8 weeks but no clinical data confirms this evolution, because patients are rarely operated again. A 75-year old patient was operated twice for recurrent glioblastoma, and a carmustine wafer was implanted during the second surgery. Eleven months later, a third surgery was performed, revealing unexpected incomplete degradation of the wafer. 1H-Nuclear Magnetic Resonance was performed to compare this wafer to pure BCNU and to an unused copolymer wafer. In the used wafer, peaks corresponding to hydrophobic units of the excipient were no longer noticeable, whereas peaks of the hydrophilic units and traces of BCNU were still present. These surprising results could be related to the formation of a hydrophobic membrane around the wafer, thus interfering with the expected diffusion and degradation processes. The clinical benefit of carmustine wafers in addition to the standard radio chemotherapy remains limited, and in vivo behavior of this treatment is not completely elucidated yet. We found that the wafer may remain after several months. Alternative strategies to deal with the blood-brain barrier, such as drug loaded liposomes or ultrasound-opening, must be explored to offer larger drug diffusion or allow repetitive delivery. PMID- 29455371 TI - Cyclic fatigue resistance of R-Pilot, WaveOne Gold Glider, and ProGlider glide path instruments. AB - OBJECTIVE: The aim of the present study was to compare the cyclic fatigue resistance of R-Pilot (VDW; Munich, Germany) with ProGlider (Denstply Sirona; Ballaigues, Switzerland) and WaveOne Gold Glider (Denstply Sirona; Ballaigues, Switzerland) glide path instruments. MATERIALS AND METHODS: R-Pilot, ProGlider, and WaveOne Gold Glider instruments were collected (n = 15) and tested in a dynamic cyclic fatigue test device, which has an artificial canal with 60 degrees angle of curvature and a 5-mm radius of curvature. All instruments were operated until fracture occurred, and both time to fracture (TF) and the lengths of the fractured fragments were recorded. Mean and standard deviations of TF and fragment length were calculated for each reciprocating system. TF data and fractured fragment length data were subjected to one-way ANOVA and post-hoc Tukey tests (P < 0.05). Also a Weibull analysis was performed on TF data. RESULTS: The cyclic fatigue resistance values of the WaveOne Gold Glider and R-Pilot were significantly higher than those of the ProGlider (P < 0.05), with no significant difference between them (P > 0.05). Weibull analysis revealed that WaveOne Gold Glider showed the highest predicted TF value for 99% survival rate, which was followed by R-Pilot and ProGlider. Regarding the length of the fractured tips, there were no significant differences among the instruments (P > 0.05). CONCLUSIONS: The reciprocating WaveOne Gold Glider and R-Pilot instruments had significantly higher cyclic fatigue resistance than rotary ProGlider instruments. CLINICAL RELEVANCE: This study reported that novel reciprocating glide path instruments exhibited higher cyclic fatigue resistance than rotating glide path instrument. PMID- 29455372 TI - Effectiveness and effect of non-vital bleaching on the quality of life of patients up to 6 months post-treatment: a randomized clinical trial. AB - OBJECTIVES: The aim of this study was to evaluate the esthetic perception of patients at 6 months after bleaching of non-vital teeth with 35% of hydrogen peroxide and 37% of carbamide peroxide using a walking bleach technique. We also assessed psychosocial impacts as well as the clinical effectiveness and stability of the color change. MATERIALS AND METHODS: The teeth bleaching treatment was randomly assigned to two groups according to the bleaching agent used: G1 HP = 35% of hydrogen peroxide (n = 25) and G2 CP = 37% of carbamide peroxide (n = 25). The non-vital bleaching was performed in four sessions using the walking bleach technique. The color was objectively (DeltaE) and subjectively (DeltaSGU) evaluated. The esthetic perception and psychosocial factors were evaluated before treatment as well as one and 6 months post-treatment using Oral Health Impact Profile (OHIP) esthetics and Psychosocial Impact of Dental Esthetics Questionnaire (PIDAQ). RESULTS: The color change (DeltaE) at 6 months (G1 = 14.53 +/- 5.07 and G2 = 14.09 +/- 6.61) for both color groups remained stable until the 6-month post-treatment (p > 0.05). There was a decrease in the values of OHIP esthetics and PIDAQ after treatment compared to the baseline (p < 0.05), and this effect was maintained 6 months post-treatment. CONCLUSIONS: Both agents were highly effective and maintained the color stability at 6 months; this positively affected the esthetic perception and psychosocial impact of patients who also remained stable over time. CLINICAL RELEVANCE: Non-vital bleaching produces a positive and stable impact on the esthetic perception and psychosocial factors at medium-term follow-ups. PMID- 29455373 TI - Diagnostic value of ultrasonography for the detection of disc displacements in the temporomandibular joint: a systematic review and meta-analysis. AB - OBJECTIVES: The aim was to assess the added diagnostic value of ultrasonography (US) for establishing the presence or absence of disc displacements (DDs) in temporomandibular joints (TMJs). MATERIALS AND METHODS: Pubmed and EMBASE were searched electronically to identify diagnostic accuracy studies that assessed the diagnostic value of US for the diagnosis of DD, using Magnetic resonance imaging (MRI) as the reference standard. Meta-analyses were performed with Metadisc 1.4 and RevMan 5.3. RESULTS: A total of 16 studies qualified for meta-analyses. For the diagnosis of DD at closed mouth position (DD-CM) and DD at maximum mouth opening position (DD-MMO), the added values of a positive result with US for ruling in DD-CM and DD-MMO were 22 and 41%, while those of a negative result with US for ruling out DD-CM and DD-MMO were 30 and 20%. For the diagnosis of DD with reduction (DDWR) and DD without reduction (DDWoR), the added values of a positive result in US for ruling in DDWR and DDWoR were 35 and 41%, while those of a negative result in US for ruling out DDWR and DDWoR were 21 and 27%. CONCLUSIONS: Using MRI as reference standard, the added values of both positive predictive values and negative predictive values of US for ruling in and ruling out DDs are sufficient in the decision-making in dental practice. CLINICAL RELEVANCE: US can be a good imaging tool to supplement clinical examination findings in patients with suspected DDs. Combined static and dynamic examinations using high resolution US should be preferred. PMID- 29455374 TI - The earnings and employment losses before entering the disability system. AB - Although a number of papers in the literature have shown the employment and wage differences between individuals receiving disability benefits and non-disabled individuals, not much is known about the potential employment and wage losses that disabled individuals suffer before being officially accepted into the disability insurance system (DI). Therefore, in this paper we compare individuals that enter into the DI system due to a progressive deterioration in the health status (ordinary illness) to similar non-disabled individuals. Our aim is to identify the differences in employment and wages between these two groups before disabled individuals are officially accepted into the DI system. We combine matching models and difference-in-difference and we find that the wage (employment) growth patterns of both groups of workers become significantly different three (five) years before entering the DI system. More specifically, our estimates suggest that 1 year before entering the system, there is a difference of 79 Euros/month in the wages of the two groups (8.3% of average wage) as well as a 7.8% point difference in employment probabilities.

PMID- 29455376 TI - Human Urine Extract Cell Differentiation Agent 2 Protects PC12 Cells from Serum Deprivation-Induced Apoptosis Accompanied with Priming of Extracellular Signal Regulated Kinase Activation and Differentiation Induction. AB - OBJECTIVE: To investigate the potential neuroprotective effect of human urine extract cell differentiation agent 2 (CDA-2) by the model of serum deprivation induced apoptosis of PC12 cells and study the underlying molecular mechanisms. METHODS: Apoptosis of PC12 cells was induced by serum deprivation. CDA-2 at doses of 0.5-4 mg/mL was used to treat the serum-deprived PC12 cells. The cellular viability was measured by sulforhodamine B binding assay and the cell apoptosis was determined by flow cytometer. Western blot was used to analyze the expression of differentiation markers and activity of extracellular signal-regulated kinase (ERK). The cellular morphology was examined under an inverted microscope. RESULTS: CDA-2 inhibited apoptotic cell death of serum-deprived PC12 cells in a dose-dependent manner. Expression of low- and mid-sized neurofilaments was observed in serum-deprived PC12 cells treated with CDA-2 or nerve growth factor (NGF). However, CDA-2 did not induce proliferation of these cells like NGF. The morphology of CDA-2 treated cells was changed from rounded to neuron-like flat polygonal shape in contrast to the extensive neurite outgrowth induced by NGF. CDA-2 transiently induced the phosphorylation of ERK in serum deprived-PC12 cells and the expression of neurofilaments induced by CDA-2 was attenuated by mitogen activated protein/extracellular signal-regulated kinase kinase (MEK) inhibitor PD98059. CONCLUSIONS: Human urine extract CDA-2 showed a potential neuroprotective activity which may correlate with ERK activation and differentiation induction. PMID- 29455377 TI - Prevalence of bacterial vaginosis in pregnant and non-pregnant Iranian women: a systematic review and meta-analysis. AB - PURPOSE: Bacterial vaginosis (BV) is a vaginal disorder which occurs either symptomatic or asymptomatic because of an imbalance between H2O2-producing Lactobacillus and Gardnerella vaginalis in the vagina. This systematic review and meta-analysis is the first to determine the prevalence of BV in pregnant and non pregnant women in Iran. METHODS: We used national (SID, Irandoc, Iranmedex and Magiran) and international (PubMed, Scopus, Google Scholar and ISI web of knowledge) electronic databases to systematically search and collect available studies using related keywords (up to 1 December 2017). Inclusion and exclusion criteria were defined to select eligible studies. RESULTS: The overall prevalence of BV among Iranian women was 18.9% (95% CI 14-25). Gardnerella vaginalis was the most prevalent isolated bacteria. The prevalence of BV in non-pregnant women was 28% (95% CI 15.1-45.9) which was higher compared with pregnant women who had a prevalence of 16.5% (95% CI 12.5-21.6). CONCLUSION: The present review revealed a high prevalence of BV in non-pregnant women. Given that BV is associated with a series of reproductive complications such as infertility, taking preventive measures such as awareness of patients as well as monitoring and controlling of syndrome are essential. PMID- 29455378 TI - Age-Related Hearing Impairment Associated NAT2, GRM7, GRHL2 Susceptibility Gene Polymorphisms and Haplotypes in Roma and Hungarian Populations. AB - Age-related hearing impairment (ARHI) is the most frequent sensory disease in the elderly, which is caused by an interaction between genetic and environmental factors. Here we examined the ethnic differences, allele and genotype frequencies of the NAT2, GRM7, and GRHL2 genes pooled samples of healthy Hungarian and healthy and hearing impaired Roma people. Study populations of healthy Hungarian and Roma subjects were characterized for the rs1799930 NAT2, rs11928865 GRM7, rs10955255, rs13263539, and rs1981361 GRHL2 polymorphisms and deaf Roma subjects were characterized for the rs1799930 NAT2, rs13263539, and rs1981361 GRHL2 using a PCR-RFLP method. We found significant differences in minor allele frequencies for GRHL2 rs13263539 and rs1981361 polymorphism between healthy Roma and Hungarian samples (37.9% vs. 51.0% and 43.6% vs. 56.2%, respectively; p < 0.05). The differences of homozygous genotype of GRHL2 rs13263539 and rs1981361 variants, values were also significantly different (13.0% vs. 25.3% and 16.5 vs. 32.3%; p < 0.05). The NAT2 rs1799930 homozygous genotype was 14.0% in healthy Romas and 7.7% in Hungarians, while the minor A allele frequency was 38.0% and 26.7% in Roma and Hungarian population, respectively (p < 0.05). Furthermore, the frequency of GGT, GAC and GAT haplotypes was significantly higher in the Hungarian population than in healthy Roma (1.87 vs. 4.47%, 0.91 vs. 2.07% and 1.15 vs. 5.51%, respectively; p < 0.008). Present study revealed significant interethnic differences in allele polymorphisms of NAT2, GRM7 and GRHL2 exhibit quite marked ethnic differences in Roma populations that might have important implications for the preventive and therapeutic treatments in this population. PMID- 29455379 TI - Comparative Study of Different Classification Models in Renal-Cell Carcinoma. AB - The aim of this study was to compare the Memorial Sloan-Kettering Cancer Center (MSKCC) and the Cleveland Clinic Foundation (CCF) models of classification of aRCC patients. In addition, the model developed from the pivotal trial of temsirolimus and those proposed by Motzer et al. in 2004, Escudier et al., Heng et al., Choueiri et al. and Bamias et al. were examined. An observational, retrospective study of patients starting first-line systemic therapy was conducted between 2008 and 2011. The variables used to evaluate the classification models were median overall survival (mOS) and median progression free survival (mPFS). The comparison of different classification models was performed by comparing the area under the ROC (Receiver Operating Characteristic) curve (AUC) for time-dependent variables proposed by Heagerty. Eighty-eight patients were included. When the different models were compared, it was found that although based on the mOS, the Escudier model had better short-term (1-year) prognostic value, followed by the Heng model; in the long term, the models that presented a higher prognosis capacity were the Hudes and CCF models, closely followed by the Heng model. In addition, the Heng model had a slightly higher predictive ability than the other models. Based on the results, and in line with the European society for medical oncology (ESMO) guidelines, it appears that the model of Heng could be the best model to classify patients with aRCC and combines good short- and long-term prognostics while possessing better predictive ability and a more equal distribution of patients. PMID- 29455380 TI - Clinical features and peripartum outcomes in pregnant women with cardiac disease: a nationwide retrospective cohort study in Japan. AB - Although the number of pregnancies in women with cardiac disease is increasing worldwide, there are few data concerning their clinical characteristics and peripartum outcomes. Using the Diagnosis Procedure Combination database between 2008 and 2014 in Japan, we retrospectively identified pregnant women who underwent high-risk delivery due to obstetric or non-obstetric comorbidities. We classified eligible women into those with pre-existing cardiac disease (cardiac disease group) and those with non-cardiac comorbidities (non-cardiac disease group) and compared their characteristics and peripartum outcomes. Of 94,364 women undergoing high-risk delivery at 556 hospitals, 857 (0.91%) had pre existing cardiac disease (302, congenital heart disease; 190, arrhythmia; 176, valvular heart disease; 120, ischemic heart disease; 65, cardiomyopathy; 4, pericardial disease). Women in the cardiac disease group were more likely to be treated at university hospitals (51.1 versus 28.6%; p < 0.001) and in intensive care units (33.5 versus 18.8%; p < 0.001) than those in the non-cardiac disease group. The proportion of cesarean deliveries was 69.4% (emergency, 28.4%; elective, 41.1%) in the cardiac disease group and 73.4% (emergency, 38.4%; elective, 35.0%) in the non-cardiac disease group. Epidural analgesia during vaginal delivery was used significantly more frequently in the cardiac disease than non-cardiac disease group (15.6 versus 2.3%; p < 0.001). Heart failure occurred more frequently in the cardiac disease than the non-cardiac disease group (10.2 versus 0.3%; p < 0.001). In cardiac subgroup comparisons, heart failure occurred more frequently in women with congenital heart disease (12.3%), valvular heart disease (12.5%), or cardiomyopathy (12.3%) than in women with arrhythmia (6.3%) or ischemic heart disease (5.8%). Multivariable logistic regression analysis showed a significant positive association between pre existing cardiac disease and risk of heart failure (adjusted odds ratio, 24.7; 95% confidence interval, 17.6-34.6; p < 0.001). No woman in the cardiac disease group died, whereas 18 women (0.02%) in the non-cardiac disease group did (p = 1.000). These findings suggest that pregnant women with pre-existing cardiac disease are at a higher risk of heart failure during the peripartum period than those with non-cardiac comorbidities. PMID- 29455381 TI - Groundwater potential mapping using C5.0, random forest, and multivariate adaptive regression spline models in GIS. AB - Ever increasing demand for water resources for different purposes makes it essential to have better understanding and knowledge about water resources. As known, groundwater resources are one of the main water resources especially in countries with arid climatic condition. Thus, this study seeks to provide groundwater potential maps (GPMs) employing new algorithms. Accordingly, this study aims to validate the performance of C5.0, random forest (RF), and multivariate adaptive regression splines (MARS) algorithms for generating GPMs in the eastern part of Mashhad Plain, Iran. For this purpose, a dataset was produced consisting of spring locations as indicator and groundwater-conditioning factors (GCFs) as input. In this research, 13 GCFs were selected including altitude, slope aspect, slope angle, plan curvature, profile curvature, topographic wetness index (TWI), slope length, distance from rivers and faults, rivers and faults density, land use, and lithology. The mentioned dataset was divided into two classes of training and validation with 70 and 30% of the springs, respectively. Then, C5.0, RF, and MARS algorithms were employed using R statistical software, and the final values were transformed into GPMs. Finally, two evaluation criteria including Kappa and area under receiver operating characteristics curve (AUC-ROC) were calculated. According to the findings of this research, MARS had the best performance with AUC-ROC of 84.2%, followed by RF and C5.0 algorithms with AUC ROC values of 79.7 and 77.3%, respectively. The results indicated that AUC-ROC values for the employed models are more than 70% which shows their acceptable performance. As a conclusion, the produced methodology could be used in other geographical areas. GPMs could be used by water resource managers and related organizations to accelerate and facilitate water resource exploitation. PMID- 29455382 TI - QSPR modeling of optical rotation of amino acids using specific quantum chemical descriptors. AB - Many chemical phenomena occur in solution. Different solvents can change the optical activity of chiral molecules. The optical rotation angles of solutes of 75 amino acids in dimethylformamide, water and methanol were analyzed using the quantitative structure-activity relationships approach. For an accurate description of chirality, we used specific quantum chemical descriptors, which reflect the properties of a chiral center, and continuous symmetry measures. The set of specific quantum chemical descriptors for atoms located near the chiral center, such as Mulliken charges, the sum of Mulliken charges on an atom (with the hydrogen charges summed up with the adjacent non-hydrogen atoms), and nuclear magnetic resoncance tensors was applied. To represent solvent effects, we used mixture-like structural simplex descriptors and quantum chemical descriptors obtained for structures optimized for specified solvent using PBE1PBE/6-31G** level of theory with the polarizable continuum model. Multiple linear regression, M5P, and locally weighted learning techniques were used to achieve accurate predictions. The specific quantum chemical descriptors proposed here demonstrated high specificity in the majority of the developed models and established direct quantitative structure-property relationships. PMID- 29455383 TI - Healthcare Experiences of Low-Income Women with Prior Gestational Diabetes. AB - Introduction An important yet understudied component of postpartum type 2 diabetes risk reduction among high risk women is experiences with the healthcare system. Our objective was to describe the healthcare experiences of a diverse, low-income sample of women with prior GDM, including their suggestions for improving care. Methods Focus groups were conducted among African American, Hispanic, and Appalachian women who were diagnosed with GDM within the past 10 years. Participants were recruited from community and medical resources. Twelve focus groups were conducted, four within each race-ethnic group. Results Three broad themes were identified around barriers to GDM care, management, and follow up: (1) communication issues; (2) personal and environmental barriers; and (3) type and quality of healthcare. Many women felt communication with their provider could be improved, including more education on the severity of GDM, streamlining information to be less overwhelming, and providing additional support through referrals to community resources. Although women expressed interest in receiving more actionable advice for managing GDM during pregnancy and for preventing type 2 diabetes postpartum, few women reported changing behaviors. Barriers to behavior change were related to cost, transportation, and competing demands. Several opportunities for improved care were elucidated. Discussion Our findings suggest that across all racial and ethnic representations in our sample, low income women with GDM experience similar communication, personal, and environmental barriers related to the healthcare they receive for their GDM. Considering the increased exposure to the health care system during a GDM affected pregnancy, there are opportunities to address barriers among women with GDM across different race-ethnic groups. PMID- 29455384 TI - Novel Interventions to Reduce Stress and Overeating in Overweight Pregnant Women: A Feasibility Study. AB - Background High stress and depression during pregnancy are risk factors for worsened health trajectories for both mother and offspring. This is also true for pre-pregnancy obesity and excessive gestational weight gain. Reducing stress and depression may be one path to prevent excessive caloric intake and gestational weight gain. Study Purpose We tested the feasibility of two novel interventions aimed at reducing stress and overeating during pregnancy. Reflecting different theoretical underpinnings, the interventions target different mechanisms. Mindful Moms Training (MMT) uses mindfulness to improve awareness and acceptance of experiences and promote conscious rather than automatic behavior choices. Emotional Brain Training (EBT) uses active coping to change perceptions of negative experience and promote positive affective states. Methods Forty-six overweight/obese low-income women were assigned to either MMT (n = 24) or EBT (n = 22) for an 8-week feasibility study. Pre-post changes in perceived stress, eating and presumed mechanisms were assessed. Results Women reported high levels of stress at baseline. Both interventions were well attended and demonstrated clinically significant pre-post reductions in stress, depressive symptoms, and improved eating behaviors. MMT significantly decreased experiential avoidance, whereas EBT significantly increased positive reappraisal; these changes were marginally significantly different by group. Conclusions This feasibility study found that both interventions promoted meaningful reductions in stress and depressive symptoms and improved reported eating behaviors in a high-risk group of pregnant women. Each intervention has a potentially different pathway acceptance for MMT and reappraisal for EBT. Larger studies are needed to test efficacy on longer term reductions in stress and overeating. PMID- 29455386 TI - (Some) current concepts in antibacterial drug discovery. AB - The rise of multidrug resistance in bacteria rendering pathogens unresponsive to many clinical drugs is widely acknowledged and considered a critical global healthcare issue. There is broad consensus that novel antibacterial chemotherapeutic options are extremely urgently needed. However, the development pipeline of new antibacterial drug lead structures is poorly filled and not commensurate with the scale of the problem since the pharmaceutical industry has shown reduced interest in antibiotic development in the past decades due to high economic risks and low profit expectations. Therefore, academic research institutions have a special responsibility in finding novel treatment options for the future. In this mini review, we want to provide a broad overview of the different approaches and concepts that are currently pursued in this research field. PMID- 29455385 TI - Transcriptome analysis of wild-type and afsS deletion mutant strains identifies synergistic transcriptional regulator of afsS for a high antibiotic-producing strain of Streptomyces coelicolor A3(2). AB - Most secondary metabolism in Actinobacteria is controlled by multi-layered, gene regulatory networks. These regulatory mechanisms are not easily identified due to their complexity. As a result, when a strong transcriptional regulator (TR) governs activation of biosynthetic pathways of target antibiotics such as actinorhodin (ACT), additional enhancement of the biosynthesis is difficult in combination with other TRs. To find out any "synergistic transcriptional regulators (sTRs)" that show an additive effect on the major, often strong, transcriptional regulator (mTR), here, we performed a clustering analysis using the transcriptome datasets of an mTR deletion mutant and wild-type strain. In the case of ACT biosynthesis in Streptomyces coelicolor, PhoU (SCO4228) and RsfA (SCO4677) were selected through the clustering analysis, using AfsS (SCO4425) as a model mTR, and experimentally validated their roles as sTRs. Furthermore, through analysis of synergistic effects, we were able to suggest a novel regulation mechanism and formulate a strategy to maximize the synergistic effect. In the case of the double TR mutant strain (DeltarsfA pIBR25::afsS), it was confirmed that the increase of cell mass was the major cause of the synergistic effect. Therefore, the strategy to increase the cell mass of double mutant was further attempted by optimizing the expression of efflux pump, which resulted in 2-fold increase in the cell mass and 24-fold increase in the production of ACT. This result is the highest ACT yield from S. coelicolor ever reported. PMID- 29455387 TI - Biochemical process of ureolysis-based microbial CaCO3 precipitation and its application in self-healing concrete. AB - Urea hydrolysis has already been considered as the most effective pathway for microbially induced CaCO3 precipitation (MICP). The present work first studied the combination of several key factors including initial pH, temperature, and dosage of urea, which contribute to the biochemical process of MICP. Under an amiable condition of pH and temperature, the dosage of urea has a significant impact on the rate of urea degradation and CaCO3 precipitation. A bacteria-based self-healing system was developed by loading healing agents on ceramsite carriers. The self-healing efficiency was evaluated by visual inspection on crack closure, compressive strength regain, and capillary water absorption. A preferable healing effectiveness was obtained when the bacteria and organic nutrients were co-immobilized in carriers. Image analysis showed that cracks up to 273 MUm could be healed with a crack closure ratio of 86% in 28 days. The compressive strength regain increased 24% and the water absorption coefficient decreased 27% compared to the reference. The findings indicated a promising application of ureolysis-based MICP in restoring the mechanical properties and enhancing the durability of concrete. PMID- 29455388 TI - Heterologous expression of rTsHyal-1: the first recombinant hyaluronidase of scorpion venom produced in Pichia pastoris system. AB - In general, hyaluronidases have a broad potential application on medicine and esthetics fields. Hyaluronidases from animal venoms cleave hyaluronan present in the extracellular matrix, acting as spreading factors of toxins into the tissues of the victim. However, the in-depth characterization of hyaluronidase from animal venoms has been neglected due to its instability and low concentration in the venom, which hamper its isolation. Thus, heterologous expression of hyaluronidase acts as a biotechnological tool in the obtainment of enough amounts of the enzyme for structural and functional studies. Therefore, this study produced a recombinant hyaluronidase from Tityus serrulatus scorpion venom, designated as rTsHyal-1, in the Pichia pastoris system. Thus, a gene for TsHyal-1 (gb|KF623285.1) was synthesized and cloned into the pPICZalphaA vector (GenScript Corporation) for heterologous expression in P. pastoris. rTsHyal-1 was expressed in laboratorial scale in a buffered minimal medium containing methanol (BMM) for 96 h with daily addition of methanol. Expression of rTsHyal-1 resulted in a total protein yield of 0.266 mg/mL. rTsHyal-1 partially purified through cation exchange chromatography presented a specific activity of 1097 TRU/mg, against 838 TRU/mg for the final expressed material, representing a 1.31-fold purification. rTsHyal-1 has molecular mass of 49.5 kDa, and treatment with PNGase F and analysis by mass spectrometry (MALDI-TOF) indicated a potential N-glycosylation of 4.5 kDa. Additionally, de novo sequencing of rTsHyal-1, performed in MALDI-TOF and Q Exactive Orbitrap MS, resulted in 46.8% of protein sequence coverage. rTsHyal-1 presents the highest substrate specificity to hyaluronan followed by chondroitin-6-sulfate, chondroitin-4-sulfate, and dermatan sulfate and showed an optimum activity at pH 6.0 and 40 degrees C. These results validate the biotechnological process for the heterologous expression of rTsHyal-1. This is the first recombinant hyaluronidase from scorpion venoms expressed in the P. pastoris system with preserved enzyme activity.

AB - OBJECTIVE: To determine aryl hydrocarbon interacting protein (AIP) gene variations and AIP and somatostatin receptor (SSTR) 1-5 immunostaining in patients with apparently sporadic acromegaly with poor versus good response to somatostatin analogues (SRLs). METHODS: A total of 94 patients (66 with poor and 28 with good response to SRLs) were screened for the AIP gene variations using Sanger sequencing. Immunostaining was performed in 60 tumors. RESULTS: Several variations, albeit some with undetermined significance, were detected, especially in poor responder patients. The prevalence of AIP mutation was 2.1% in the whole group and 1.5% in patients with poor response to SRLs. AIP, SSTR2A, and SSTR2B immunostainings were decreased in patients with poor response (p < 0.05 for all), and other SSTRs did not differ between the groups (p > 0.05 for all). Patients with low AIP had decreased levels of SSTR2A and SSTR3 (p < 0.05 for all). AIP and SSTR2A immunostainings were positively correlated to the treatment response and age at diagnosis was negatively correlated (p < 0.05 for all). In poor responder patients with high SSTR2A immunostaining, SSTR2B immunostaining and preoperative tumor size were positively and negatively correlated, respectively, to SRL response (p < 0.05 for all). CONCLUSIONS: Lack of response to SRLs does not necessarily increase the risk of harboring AIP mutations. The finding of decreased AIP, SSTR2A, and SSTR2B immunostaining in patients with poor response to SRLs and decreased SSTR2A and SSTR3 level in those with low AIP immunostaining suggests a possible interaction between AIP and some SSTR subtypes that might alter SRL sensitivity. PMID- 29455390 TI - Utility of multiple rule out CT screening of high-risk atraumatic patients in an emergency department-a feasibility study. AB - BACKGROUND: Several large trials have evaluated the effect of CT screening based on specific symptoms, with varying outcomes. Screening of patients with CT based on their prognosis alone has not been examined before. For moderate-to-high risk patients presenting in the emergency department (ED), the potential gain from a CT scan might outweigh the risk of radiation exposure. We hypothesized that an accelerated "multiple rule out" CT screening of moderate-to-high risk patients will detect many clinically unrecognized diagnoses that affect change in treatment. METHOD: Patients >= 40 years, triaged as high-risk or moderate-to-high risk according to vital signs, were eligible for inclusion. Patients were scanned with a combined ECG-gated and dual energy CT scan of cerebrum, thorax, and abdomen. The impact of the CT scan on patient diagnosis and treatment was examined prospectively by an expert panel. RESULTS: A total of 100 patients were included in the study, (53% female, mean age 73 years [age range, 43-93]). The scan lead to change in treatment or additional examinations in 37 (37%) patients, of which 24 (24%) were diagnostically significant, change in acute treatment in 11 (11%) cases and previously unrecognized malignant tumors in 10 (10%) cases. The mean size specific radiation dose was 15.9 mSv (+/- 3.1 mSv). CONCLUSION: Screening with a multi-rule out CT scan of high-risk patients in an ED is feasible and result in discovery of clinically unrecognized diagnoses and malignant tumors, but at the cost of radiation exposure and downstream examinations. The clinical impact of these findings should be evaluated in a larger randomized cohort. PMID- 29455391 TI - Focal Ischaemic Infarcts Expand Faster in Cerebellar Cortex than Cerebral Cortex in a Mouse Photothrombotic Stroke Model. AB - It is generally accepted that the cerebellum is particularly vulnerable to ischaemic injury, and this may contribute to the high mortality arising from posterior circulation strokes. However, this has not been systematically examined in an animal model. This study compared the development and resolution of matched photothrombotic microvascular infarcts in the cerebellar and cerebral cortices in adult 129/SvEv mice of both sexes. The photothrombotic lesions were made using tail vein injection of Rose Bengal with a 532 nm laser projected onto a 2 mm diameter aperture over the target region of the brain (with skull thinning). Infarct size was then imaged histologically following 2 h to 30-day survival using serial reconstruction of haematoxylin and eosin stained cryosections. This was complemented with immunohistochemistry for neuron and glial markers. At 2 h post-injury, the cerebellar infarct volume averaged ~ 2.7 times that of the cerebral cortex infarcts. Infarct volume reached maximum in the cerebellum in a quarter of the time (24 h) taken in the cerebral cortex (4 days). Remodelling resolved the infarcts within a month, leaving significantly larger residual injury volume in the cerebellum. The death of neurons in the core lesion at 2 h was confirmed by NeuN and Calbindin immunofluorescence, alongside activation of astrocytes and microglia. The latter persisted in the region within and surrounding the residual infarct at 30 days. This comparison of acute focal ischaemic injuries in cerebellar and cerebral cortices provides direct confirmation of exacerbation of neuropathology and faster kinetics in the cerebellum. PMID- 29455392 TI - The psychometric evaluation of the quality of life in short stature youth (QoLISSY) instrument for German children born small for gestational age. AB - PURPOSE: This study aimed to validate the disease-specific "quality of life in short stature youth (QoLISSY)-instrument" that assessesQuery the health-related quality of life (HrQoL) in German children and adolescents diagnosed as small for gestational age (SGA) in a patient and parent report. METHODS: The psychometric performance of the German version of the QoLISSY questionnaire was examined in terms of reliability and validity in 65 SGA families (17 child reports/64 parent reports) and compared to the psychometric performance of the original European QoLISSY dataset of over 200 children with growth hormone deficiency and idiopathic short stature (ISS). RESULTS: The analysis yielded psychometrically favorable results with excellent reliability and acceptable discriminant validity. The instrument's operating characteristics were comparable to the results of the original European QoLISSY data. In the parent- as well as child report, children with SGA had lower HrQoL scores than children with ISS. Convergent validity was demonstrated by significant correlations between the QoLISSY scales and the generic KIDSCREEN-10 Index. CONCLUSION: Psychometric testing suggests that QoLISSY is a promising instrument to assess the HrQoL of young German people with SGA. Both versions (parent- and child report) appear to detect differences between SGA and other conditions (e.g. ISS). QoLISSY can be used in clinical studies, health service research, as well as in practice in children with SGA and their parents. For a cross-cultural application of the instrument in SGA, the tool needs be validated in sufficiently large SGA samples within respective countries. PMID- 29455393 TI - Mangiferin inhibits cell migration and invasion through Rac1/WAVE2 signalling in breast cancer. AB - Breast tumour progression results from the advancement of the disease to a metastatic phenotype. Rac1 and Cdc42 belong to the Rho family of genes that, together with their downstream effectors, Wiskott-Aldrich Syndrome protein-family verprolin-homologous protein 2 (WAVE2) and Arp2/3, assume a vital part in cytoskeletal rearrangement and the arrangement of film projections that advance malignant cell relocation and invasion. Mangiferin is a characteristic polyphenolic compound from Mangifera indica L. (Anacardiaceae), ordinarily referred to as mango, that is consumed worldwide as a natural product, including culinary and seasoning applications. Mangiferin delays breast malignancy development and progression by inhibiting different signalling pathways required in mitogenic signalling and metastatic progression. Studies were performed to analyse the impact of mangiferin on Rac1/WAVE2 flagging, relocation and invasion in highly metastatic human MDA-MB-231 mammary cells. Additional studies led to the observation that comparative treatment with mangiferin caused marked reduction in tumour cell movement and invasion. Taken together, these discoveries demonstrate that mangiferin treatment adequately hinders Rac1/WAVE2 flagging and diminishes metastatic phenotypic expression in malignant mammary cells, indicating that mangiferin may provide a benefit as a novel restorative approach in the treatment of metastatic breast cancer. PMID- 29455394 TI - Culture in embryonic kidney serum and xeno-free media as renal cell carcinoma and renal cell carcinoma cancer stem cells research model. AB - The use of fetal bovine serum hinders obtaining reproducible experimental results and should also be removed in hormone and growth factor studies. In particular hormones found in FBS act globally on cancer cell physiology and influence transcriptome and metabolome. The aim of our study was to develop a renal carcinoma serum free culture model optimized for (embryonal) renal cells in order to select the best study model for downstream auto-, para- or endocrine research. Secondary aim was to verify renal carcinoma stem cell culture for this application. In the study, we have cultured renal cell carcinoma primary tumour cell line (786-0) as well as human kidney cancer stem cells in standard 2D monolayer cultures in Roswell Park Memorial Institute Medium or Dulbecco's Modified Eagle's Medium and Complete Human Kidney Cancer Stem Cell Medium, respectively. Serum-free, animal-component free Human Embryonic Kidney 293 media were tested. Our results revealed that xeno-free embryonal renal cells optimized culture media provide a useful tool in RCC cancer biology research and at the same time enable effective growth of RCC. We propose bio-mimic RCC cell culture model with specific serum-free and xeno-free medium that promote RCC cell viability. PMID- 29455395 TI - Anti-cancer effect of Aquaporin 5 silencing in colorectal cancer cells in association with inhibition of Wnt/beta-catenin pathway. AB - Aquaporin 5 (AQP5) is a water channel protein that is over-expressed in many tumors. Elevated expression of AQP5 is associated with poor prognosis of colorectal cancer. Yet, whether AQP5 plays a role in epithelial-mesenchymal transition (EMT) of colorectal cancer has not been reported until now. Here we aim to investigate the function of AQP5 in the EMT process of colorectal cancer. We transfected HCT116 and SW480 cells with AQP5-specific shRNA and verified the knockdown efficiency through western blotting and real-time PCR. Afterwards, scratch wound healing assay, invasion assay, gelatin zymography, immunofluorescence staining and immunoblotting were performed to assess the effect of AQP5 silencing in these two cells. The ability of migration and invasion of colorectal cancer cells was significantly impaired after AQP5 silencing. Correspondingly, the activity and expression of Matrix Metallopeptidase (MMP)-2 and MMP-9 were reduced. Moreover, the expression levels of EMT-related factors were altered: E-cadherin, Tissue Inhibitor Of Metalloproteinases (TIMP)-1 and TIMP-2 were upregulated, whereas Vimentin, N cadherin, Plasminogen Activator, Urokinase (uPA) and Snail were downregulated following knockdown of AQP5 in colorectal cancer cells. Furthermore, the expression of Wnt1 and beta-catenin was markedly decreased after AQP5 knockdown. Interestingly, the alteration of EMT-related factors mediated by AQP5 knockdown could be reversed by upregulation of beta-catenin. Taken together, silencing of AQP5 restrained the migration and invasion of colorectal cancer cells, and regulated the expression of EMT-related molecules in them by inhibiting Wnt/beta catenin pathway.

AB - The aim of this work is to review the MR imaging of neoplastic and non-neoplastic lesions of the brain and spine in neurofibromatosis type I. Neoplastic lesions are optic pathway gliomas, brain stem gliomas, other gliomas of the brain, and peripheral nerve sheath tumors. Structural changes in the brain include unidentified bright objects, macrocephaly, and enlarged corpus callosum.

PMID- 29455399 TI - Human figure drawing distinguishes Alzheimer's patients: a cognitive screening test study. AB - To study human figure drawing in a group of Alzheimer's disease (AD) patients and compare it with a group of patients with mild cognitive impairment (MCI) and controls. We evaluated consecutive outpatients over a one-year period. Patients were classified as affected by AD or by MCI. All patients and controls underwent a simplified version of the human-figure drawing test and MMSE. A qualitative and quantitative analysis of all human figures was obtained. 112 AD, 100 MCI patients and 104 controls were enrolled. AD patients drew human figures poor in details and globally smaller than MCI patients and controls. Human figures drawn by MCI patients are intermediate in body height between those of the AD patients and the healthy subjects. The head-to-body ratio of human figures drawn by AD patients is greater than controls and MCI patients, while the human figure size-relative-to page space index is significantly smaller. Body height is an independent predictor of cognitive impairment correlating with its severity and with the number of the figure's details. Human figures drawn by AD patients are different from those drawn by healthy subjects and MCI patients. Human figure drawing test is a useful tool for orienting cognitive impairment's diagnosis.

PMID- 29455401 TI - New clinical characteristics and risk factors of hand knob infarction. AB - Hand knob infarction (HKI) is a rare clinical condition which is often misdiagnosed as peripheral neuropathy. This study aimed to identify the clinical characteristics and risk factors of HKI. Nine HKI patients admitted between January 2013 and March 2016 were confirmed by magnetic resonance imaging. Their medical records were collected and analyzed. The modified Rankin Scale was used to assess clinical outcomes. Routine laboratory tests, electrocardiogram, echocardiography, cranial magnetic resonance imaging, magnetic resonance angiography, computed tomography angiography, and Doppler ultrasonography examinations were performed. Seven patients had uniform involvement of all digits. One patient with radial weakness had a lesion in the lateral area of hand knob, and another patient with ulnar weakness had a lesion distributed in the medial area of hand knob. Hyperhomocysteinemia was a most common risk factor for HKI. Most HKI patients had a benign disease course, but three patients (33.33%) with the stroke type of large artery atherosclerosis had disease recurrence. We characterized clinical characteristics and risk factors of HKI which will help the diagnosis and management of HKI.

AB - Despite the availability of nucleic acid amplification tests (NAATs), most of aseptic acute meningitides, encephalitides, and meningoencephalitides (AAMEMs) in adults remain of unknown etiology so far. To shed light on such topic, we aimed to evaluate potential predictors for AAMEMs of unknown origin. We collected retrospectively data from all consecutive cases of AAMEMs in adults discharged from an Italian referral hospital, from January 2004 to December 2016. Laboratory analysis included common immunometric methods and NAATs. Potential predictors for unknown etiology (age, seasonality, serum C-reactive protein value, antibiotic use before lumbar puncture, immunodeficiency conditions, clinical symptoms and signs) were evaluated by a logistic regression analysis model. A p value <= 0.05 was considered to indicate statistical significance. The study included 92 patients (median age 39 years; 54.3% males) affected by meningitis (n = 57), encephalitis (n = 25), and meningoencephalitis (n = 10). The identified agents that cause AAMEMs were herpesviruses (20.7%), enteroviruses (5.4%), tick-borne encephalitis virus (3.3%), influenza virus A (2.2%), West Nile virus (1.1%), and parvovirus B19 (1.1%), while 66.3% of cases were of unknown etiology. No predictor was found to be significantly associated with AAMEMs of unknown etiology. We suggest that potential infectious agents causing undiagnosed cases should be investigated among non-bacterial, non-opportunistic, and non-seasonal organisms. PMID- 29455404 TI - The Effect of Pre-Surgery Information Online Lecture on Nutrition Knowledge and Anxiety Among Bariatric Surgery Candidates. AB - INTRODUCTION: Best practices for patient education in bariatric surgery (BS) remain undefined. The aims of this study were to evaluate the effect of an online lecture on nutrition knowledge, weight loss expectations, and anxiety among BS candidates and present a new tool to assess this knowledge before BS. METHODS: An interventional non-randomized controlled trial on 200 BS candidates recruited while attending a pre-BS committee. The first 100 consecutive patients were assigned to the control group and the latter 100 consecutive patients to the intervention group and were instructed to watch an online lecture of 15-min 1-2 weeks prior to surgery. All participants completed a BS nutrition knowledge and the state-trait anxiety inventory (STAI) questionnaires at the pre-BS committee and once again at the pre-surgery clinic. Body mass index (BMI), comorbidities, surgery type, marital status, and number of dietitian sessions were obtained from medical records. RESULTS: Data for paired study questionnaires scores were available for 128 patients (n = 69 and n = 59 for the control and intervention groups, respectively), with a mean age and BMI of 40.3 +/- 11.4 years and 41.3 +/ 4.9 kg/m2, respectively. The BS nutrition knowledge and the state anxiety scores increased for both study groups at the pre-surgery clinic as compared to the pre BS committee (P <= 0.028), but the improvement in the nutrition knowledge score was significantly higher for the intervention group (P = 0.030). No within or between-group differences were found for the trait anxiety items score. The "dream" and "realistic" weight goals were lower than the expected weight loss according to 70% excess weight loss (EWL) for both study groups at both time points (P < 0.001 for all). CONCLUSION: Education by an online lecture prior to the surgery improves BS nutrition knowledge, but not anxiety. ClinicalTrials.gov number: NCT02857647. PMID- 29455405 TI - Bariatric Surgery in Patients on Chronic Anticoagulation Therapy. AB - BACKGROUND: Perioperative management of chronically anti-coagulated patients undergoing bariatric surgery requires a balance of managing hemorrhagic and thromboembolic risks. The aim of this study is to evaluate the incidence of hemorrhagic complications and their management in chronically anticoagulated (CAT) patients undergoing bariatric surgery. METHODS: A retrospective review of CAT patients undergoing bariatric surgery at an academic center from 2008 to 2015 was studied. RESULTS: A total of 153 patients on CAT underwent surgery [Roux-en-Y gastric bypass (n = 79), sleeve gastrectomy (n = 63), and adjustable gastric banding (n = 11)] during the study period: 85 patients (55%) were females; median age was 56 years (interquartile range [IQR] 49-64), and median BMI was 49 kg/m2 (IQR 43-56). The most common indications for CAT were venous thromboembolism (n = 87) and atrial fibrillation (n = 83). Median duration of procedure and estimated intraoperative blood loss was 150 min (IQR 118-177) and 50 ml (IQR 25-75), respectively. Thirty-day postoperative complications were reported in 33 patients (21.6%) including postoperative bleeding (n = 19), anastomotic leak (n = 3), and pulmonary embolism (n = 1). Nineteen patients (12%) with early postoperative bleeding were further categorized to intra-abdominal (n = 10), intraluminal (n = 6), and at the port site or abdominal wall (n = 3). All-cause readmissions within 30 days of surgery occurred in 19 patients (12%). There was no 30-day mortality. CONCLUSION: In our experience, patients who require chronic anticoagulation medication are higher than average risk for postoperative complications and all cause readmission rates. Careful surgical technique and close attention to postoperative anticoagulation protocols are essential to decrease perioperative risk in this high-risk cohort. PMID- 29455406 TI - Conversional Weight Loss Surgery: an Australian Experience of Converting Laparoscopic Adjustable Gastric Bands to Laparoscopic Sleeve Gastrectomy. AB - BACKGROUND: Bariatric surgery is the most effective treatment for severe obesity, capable of producing more than 50% excess weight loss at 10-year follow-up (James Clin Dermatol 1; 22:276-80; O'Brien Br J Surg 2; 102:611-17; Buchwald et al. Metab Syndr 3; 347-56). The success of bariatric surgery extends far beyond weight loss, with up to 80-90% of patients having improvement or resolution of many of their weight-related co-morbidities including type II diabetes mellitus and hypertension (Puzziferri et al. JAMA 4; 312:934-42; Buchwald et al. Am J Med 5; 122:248-56). However, there is a paucity of data regarding conversional bariatric surgery. OBJECTIVE: This study aims to explore the efficacy, safety and feasibility of conversional surgery. SETTING: This study represents the largest Australasian series focusing on conversional bariatric surgery. The study was conducted in the Norwest Private Hospital and Hospital for Specialist Surgery (HSS), both private Hospitals in Sydney, Australia. METHODS: Data was collected prospectively at regular intervals for more than 12 months from 1 January 2012 to 1st November 2015 for all patients requiring a laparoscopic sleeve gastrectomy (LSG) as secondary procedure after prior laparoscopic adjustable gastric band (LAGB). Excess weight loss (EWL), percentage total body weight loss (TWL) and excess BMI loss (EBMIL) as well as any complications were recorded. RESULTS: There were low rates of morbidity (1.1%) and no mortality at 12-month follow-up. Satisfactory EWL of 60% (95% CI: 56.6-63.4%), EBMIL of 60.1% (95% CI: 48.8-71.4%) and 16% TWL was achieved at 12-month follow-up. CONCLUSION: We therefore conclude that sleeve gastrectomy is a safe and valid option for conversional bariatric surgery following LAGB. PMID- 29455407 TI - A Single-center Experience Examining the Length of Stay and Safety of Early Discharge After Laparoscopic Roux-en-Y Gastric Bypass Surgery. AB - PURPOSE: This study's objective was to describe our experience and evaluate the safety of early discharge (ED) following laparoscopic Roux-en-Y gastric bypass (LRYGB) in a specific patient population. MATERIALS AND METHODS: Patients undergoing LRYGB at Montefiore Medical Center were retrospectively reviewed. Patients readmitted in the first 30 days following surgery were compared to those patients who were not readmitted. Data analysis was used to compare groups and to determine factors associated with readmission. In addition to patient demographics, length of stay (LOS) was analyzed as an independent risk factor for readmission. RESULTS: A total of 630 LRYGB were performed during this period. There were 5.1% (n = 32) of patients that required readmission within 30 days of discharge. Readmitted patients had a higher BMI (50.0 vs. 45.8; p = 0.006) and there was a trend for them to be younger (38.4 years vs. 42.0; p = 0.07). There was an increased rate of ED in 2015 (36.7%, n = 121) compared to 2014 (29.9%, n = 90). The readmission rate for ED for the study period was 4.7% (n = 10). There were no observed mortalities in our early discharge group of patients. CONCLUSIONS: Discharge on post-operative day 1 following a LRYGB is safe and is not associated with an increased likelihood of being readmitted within 30 days of discharge. Our single-center experience helps to better characterize current patient profiles and length of stay trends within the field and can be used to establish a randomized controlled trial for discharging patients early after LRYGB. PMID- 29455408 TI - Frequency and treatment of hydrocephalus prior to and after posterior fossa tumor surgery in adult patients. AB - BACKGROUND: There is paucity of information about the frequency of hydrocephalus prior to and after posterior fossa tumor surgery in adult patients and about the best way it should be managed. The present study was conducted to determine the frequency of hydrocephalus prior to and after posterior fossa tumor surgery in adult patients as well as the value of an endoscopic third ventriculostomy (ETV) prior to posterior fossa tumor surgery with regard to the rate of perioperative complications and persistent hydrocephalus. METHODS: A single-institution retrospective chart review of all posterior fossa tumor surgeries of our department in a 10-year period (2005 to 2014) has been done. RESULTS: Fifty-two of 243 adult patients with posterior fossa tumors presented with hydrocephalus at the time of admission prior to tumor surgery. 39/52 received early tumor surgery, 11/52 an ETV prior to tumor surgery and in 2/52 an external ventricular drainage (EVD) was inserted prior to tumor surgery. 3/52 patients required a permanent cerebrospinal fluid (CSF) diverting procedure for persistent hydrocephalus after tumor removal. One hundred ninety-one patients did not demonstrate a hydrocephalus before surgical treatment and four of them developed a post resection hydrocephalus. CONCLUSION: The frequency of hydrocephalus prior to posterior fossa tumor surgery in adult patients is 21.4% and therefore much lower than in respective reports of pediatric patients. The risk of persistent hydrocephalus and newly developed hydrocephalus after tumor surgery was very low, too (5.7 and 2.1%, respectively). An ETV is not justified in every adult patient prior to posterior fossa tumor surgery. PMID- 29455409 TI - How I do it: endoscopic endonasal approach to the inferior third of the clivus. AB - BACKGROUND: Nowadays, endoscopic endonasal expanded approach targeting for the clival lower third is well described in literature. Nonetheless, great variations can be found among surgical groups, specially during the earlier stages of this procedure. METHOD: We present a step by step description of the clival lower third approach until entering the dural space, setting its bony limits. We describe the basipharyngeal flap tailoring as a helpful option for latter reconstruction. The study of cadaveric specimens adds clarifying dissections. CONCLUSIONS: The expansion in the coronal plane is providential in most of the intradural lesions of the inferior clivus. Basipharyngeal flap may help seal the surgical defects in this area. PMID- 29455410 TI - Can patients with symptomatic Tarlov cysts be differentiated from patients with specific low back pain based on comprehensive history taking? AB - BACKGROUND: Tarlov cysts (TCs) are expanded nerve root sheaths that occur near the dorsal root ganglion and result from increased intraspinal hydrostatic pressure. TCs most frequently affect the lumbosacral plexus and therefore may cause specific symptoms such as perineal pain and neurogenic bladder, bowel, and sphincter problems. It has been estimated that 1% of the population has symptomatic Tarlov cysts (STCs). However, STCs appear to be underdiagnosed, with the pain reported by patients commonly attributed to degenerative alterations seen on MRI. The aim of the present study is to investigate the utility of a comprehensive questionnaire for use by physicians in establishing the diagnosis of STCs. METHODS: We compared questionnaire responses regarding patient history between 33 patients diagnosed with symptomatic TCs and 42 patients with chronic low back pain and sciatica due to disc problems or degenerative or inflammatory disorders. The diagnosis of STCs was confirmed using nerve conduction studies (NCS) and electromyography (EMG) of the sacral myotomes by an expert neurophysiologist. RESULTS: The questionnaire responses revealed specific differences in perineal symptoms (perineal pain, dyspareunia, coccygodynia), bowel symptoms (constipation, diarrhea), bladder symptoms (hesitation, retention, frequency), and anal sphincter problems (anal pain, mild fecal incontinence). Additionally, sitting, walking, and straining aggravated pain more frequently in STC patients, and STC patients were more often forced to stop working and/or reduce their social activities. CONCLUSIONS: Including the above-listed items in the patient history might facilitate differentiation of low back pain and sciatica due to STCs from that due to disc problems or degenerative or inflammatory disorders. PMID- 29455411 TI - Completion of Gamma Knife radiosurgery for AVM treatment after unplanned interruption-technical note. AB - BACKGROUND AND IMPORTANCE: Gamma Knife radiosurgery is an established technique for non-urgent treatment of various intracranial pathologies. Intra-procedural dislodgement of the stereotactic frame is an uncommon occurrence that could lead to abortion of ongoing treatment and necessitate more invasive treatment strategies. CLINICAL PRESENTATION: In this case report, we describe a novel method for resumption of Gamma Knife treatment after an unplanned intra procedural interruption. The case example involves a radiosurgical treatment of a Spetzler-Martin grade I arteriovenous malformation. CONCLUSION: Our technique involves integration of scans and coordinate systems from two imaging sessions using the composite isodose line to resolve translational differences, thereby limiting delivery of remaining shots to the untreated region of the lesion. MRI follow-up at 13 months showed a reduction in the nidus size with no evidence of any radiation injury to the surrounding brain parenchyma. We believe this technique will allow care teams to effectively salvage interrupted Gamma Knife procedures and reduce progression to more invasive treatment options. PMID- 29455413 TI - Influence of ABO blood type on the outcome after non-aneurysmal subarachnoid hemorrhage. AB - BACKGROUND: In patients with non-aneurysmal subarachnoid hemorrhage (NA-SAH), the etiology is unknown and the bleeding source remains unidentified. However, the ABO blood type system has a profound role in patient's hemostasis and thrombosis. To date, the aspect of ABO blood type in incidence, clinical course, and outcome after NA-SAH has not been investigated. METHODS: In this retrospective analysis, 81 patients with non-traumatic and non-aneurysmal subarachnoid hemorrhage treated between 2010 and 2014 at the author's institution were included. WFNS admission status, cerebral vasospasm, delayed infarction, ventriculoperitoneal shunt necessity, the Fisher grade, and the modified Rankin Scale were analyzed for their association with ABO blood type. Four hundred seventy patients with aneurysmal subarachnoid hemorrhage served as a control group. RESULTS: The AB blood type is more frequent in NA-SAH compared to aneurysmal patients and the German population (OR 2.45, p <= 0.05). Furthermore, NA-SAH with AB blood type showed a similar sequelae compared to aneurysmal patients in terms of shunt necessity (OR 2.00, p >= 0.05), cerebral vasospasm (OR 1.66, p >= 0.05), and delayed infarctions (OR 1.07, p >= 0.05). CONCLUSION: The clinical course of NA SAH AB blood type patients shows similar severity as of aneurysmal subarachnoid hemorrhage.

A 39-year-old woman is reported who was found deceased with incised wounds to the dorsa of both hands that resembled defense wounds. Examination of the flexor surfaces of both wrists, however, revealed horizontal incised wounds typical of self-infliction. Perfusion of the subclavian arteries produced leakage of water from peripheral veins within wounds on both hands and the right wrist. Death was due to exsanguination from incised wounds of the hands and right wrist; manner suicide. This case demonstrates the difficulties that may arise in differentiating self-inflicted from assaultive wounds. On occasion suicidal sharp force injuries may be multiple and in atypical locations. In these circumstances a high index of suspicion for homicide must be maintained. PMID- 29455414 TI - Defining G protein-coupled receptor peptide ligand expressomes and signalomes in human and mouse islets. AB - INTRODUCTION: Islets synthesise and secrete numerous peptides, some of which are known to be important regulators of islet function and glucose homeostasis. In this study, we quantified mRNAs encoding all peptide ligands of islet G protein coupled receptors (GPCRs) in isolated human and mouse islets and carried out in vitro islet hormone secretion studies to provide functional confirmation for the species-specific role of peptide YY (PYY) in mouse islets. MATERIALS AND METHODS: GPCR peptide ligand mRNAs in human and mouse islets were quantified by quantitative real-time PCR relative to the reference genes ACTB, GAPDH, PPIA, TBP and TFRC. The pathways connecting GPCR peptide ligands with their receptors were identified by manual searches in the PubMed, IUPHAR and Ingenuity databases. Distribution of PYY protein in mouse and human islets was determined by immunohistochemistry. Insulin, glucagon and somatostatin secretion from islets was measured by radioimmunoassay. RESULTS: We have quantified GPCR peptide ligand mRNA expression in human and mouse islets and created specific signalomes mapping the pathways by which islet peptide ligands regulate human and mouse GPCR signalling. We also identified species-specific islet expression of several GPCR ligands. In particular, PYY mRNA levels were ~ 40,000-fold higher in mouse than human islets, suggesting a more important role of locally secreted Pyy in mouse islets. This was confirmed by IHC and functional experiments measuring insulin, glucagon and somatostatin secretion. DISCUSSION: The detailed human and mouse islet GPCR peptide ligand atlases will allow accurate translation of mouse islet functional studies for the identification of GPCR/peptide signalling pathways relevant for human physiology, which may lead to novel treatment modalities of diabetes and metabolic disease.

AB - IKKbeta has previously been implicated in breast cancer bone metastasis and bone remodelling. However, the contribution of IKKbeta expressed by bone cells of the tumour microenvironment to breast cancer-induced osteolysis has yet to be investigated. Here, we studied the effects of the verified selective IKKbeta inhibitors IKKbetaIII or IKKbetaV on osteoclast formation and osteoblast differentiation in vitro and in vivo, human and mouse breast cancer cells' support for osteoclast formation and signalling in vitro and osteolysis ex vivo and in immunocompetent mice after supracalvarial injection of human MDA-MB-231 conditioned medium or intra-cardiac injection of syngeneic 4T1 breast cancer cells. Pre-treatment with IKKbetaIII or IKKbetaV prior to exposure to tumour derived factors from human and mouse breast cancer cell lines protected against breast cancer-induced osteolysis in two independent immunocompetent mouse models of osteolysis and the ex vivo calvarial bone organ system. Detailed functional and mechanistic studies showed that direct inhibition of IKKbeta kinase activity in osteoblasts and osteoclasts was associated with significant reduction of osteoclast formation, enhanced osteoclast apoptosis and reduced the ability of osteoblasts to support osteoclastogenesis in vitro. When combined with previous findings that suggest NFkappaB inhibition reduces breast cancer tumorigenesis and metastasis our present findings have an important clinical implication on raising the possibility that IKKbeta inhibitors, as bone anabolics, osteoclast inhibitors as well as anti-metastatic agents, may have advantages over anti-osteoclasts agents in the treatment of both skeletal and non-skeletal complications associated with metastatic breast cancer. PMID- 29455418 TI - Preoperative chemotherapy with docetaxel, cisplatin, and 5-fluorouracil for locally advanced esophageal carcinosarcoma: a case report and review of the literature. AB - BACKGROUND: Esophageal carcinosarcoma is a relatively rare malignant neoplasm composed of both epithelial carcinomatous and mesenchymal sarcomatous elements. There is no recommended clinical treatment for esophageal carcinosarcoma because of the rarity of the disease. This report describes a case of esophageal carcinosarcoma that was effectively treated with docetaxel, cisplatin, and 5 fluorouracil as preoperative chemotherapy. CASE PRESENTATION: A 73-year-old man had a chief complaint of dysphagia with epigastric pain. Esophagogastroduodenoscopy (EGD) revealed a polypoid neoplasm combined with an infiltrative ulcer that exhibited a mixture of squamous cell carcinoma and spindle cell sarcoma histologically. Computed tomography findings showed swollen lymph nodes in the mediastinum and around the cardia. We diagnosed esophageal carcinosarcoma cT3N1M0 cStage III. After preoperative chemotherapy with docetaxel, cisplatin, and 5-fluorouracil, the patient underwent thoracoscopic esophagectomy with three-field lymph node dissection. Histological findings revealed that the sarcomatous component had completely disappeared and the carcinomatous component was only confined by the basement membrane with scar formation of the muscularis propria. Mural fibrotic lesions were observed in several resected regional lymph nodes. Hence, immediately after preoperative therapy, the esophageal carcinosarcoma was diagnosed as ypTisN0M0 fStage I. The patient remained alive without tumor recurrence at 12 months after the operation. CONCLUSIONS: A review of the literature revealed that there is still no established therapeutic strategy for locally advanced esophageal carcinosarcoma, especially against the sarcomatous component. We herein provide the first report in which the sarcomatous component showed a complete response to preoperative chemotherapy with docetaxel, cisplatin, and 5-fluorouracil. Preoperative chemotherapy with docetaxel, cisplatin, and 5-fluorouracil followed by esophagectomy with extended lymphadenectomy may achieve definitive treatment for locally advanced esophageal carcinosarcoma. PMID- 29455417 TI - Effect of Yulangsan Polysaccharide on the Reinstatement of Morphine-Induced Conditioned Place Preference in Sprague-Dawley Rats. AB - We previously reported that Yulangsan polysaccharide (YLSP), which was isolated from the root of Millettia pulchra Kurz, attenuates withdrawal symptoms of morphine dependence by regulating the nitric oxide pathway and modulating monoaminergic neurotransmitters. In this study, we investigated the effects and mechanism of YLSP on the reinstatement of morphine-induced conditioned place preference (CPP) in rats. A CPP procedure was employed to assess the behavior of rats, and indicators of serum and four brain regions (nucleus accumbens, ventral tegmental area, hippocampus and prefrontal cortex) were determined to explore its underlying mechanism. YLSP inhibited priming morphine-induced reinstatement of CPP in a dose-dependent manner. YLSP markedly reduced nitric oxide and nitric oxide synthase levels in the brain. Moreover, YLSP significantly decreased the dopamine and norepinephrine levels in the serum and brain. Furthermore, YLSP significantly decreased cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP) concentrations, inhibited the expression of dopamine D1 receptors and cAMP response element binding protein mRNA, and improved the expression of dopamine D2 receptor mRNA in the four brain regions. Our findings indicated that YLSP could inhibit the reinstatement of morphine induced CPP possibly by modulating the NO-cGMP and D1R-cAMP signaling pathways.

AB - Toxoplasma gondii, the etiological agent of toxoplasmosis, infects nucleated cells and then resides and multiplies within a parasitophorous vacuole. For this purpose, the parasite secretes many virulence factors for the purpose of invading and subverting the host microbicidal defenses in order to facilitate its survival in the intracellular milieu. Essential metals are structural components of proteins and enzymes or cofactors of enzymatic reactions responsible for these parasitic survival mechanisms. However, an excess of non-essential or essential metals can lead to parasite death. Thus, infected host cells were incubated with 20 MUM ZnCl2 in conjunction with 3 MUM CdCl2 or HgCl2 for 12 h in order to investigate cellular events and organelle damage related to intracellular parasite death and elimination. In the presence of these metals, the tachyzoites undergo lipid uptake and transport impairment, functional and structural mitochondrial disorders, DNA condensation, and acidification of the parasitophorous vacuole, thus leading to parasite death. Additional research has suggested that lysosome-vacuole fusion was involved in parasite elimination since acid phosphatases were found inside the parasitophorous vacuole, and vacuoles containing parasites were also positive for autophagy. In conclusion, low concentrations of CdCl2, HgCl2, and ZnCl2 can cause damage to Toxoplasma gondii organelles, leading to loss of viability, organelle death, and elimination without causing toxic effects to host cells. PMID- 29455420 TI - Molecular characterization of Hepatozoon canis from farm dogs in Pakistan. AB - Hepatozoon canis is a tick-borne pathogen of canids, which is distributed worldwide. However, very little is known about this protozoan parasite in Pakistan. This study provides the first molecular evidence of H. canis from farm dogs from three agro-ecological zones of Punjab, Pakistan. A conventional PCR targeting the 18S rRNA gene was used to characterize H. canis from farm dogs from three districts, namely Kasur, Rawalpindi, and Muzaffargarh, in Punjab. Of 341 blood samples tested, 155 (45.5%) were positive for H. canis, 73 (61.3%) from Kasur, 46 (42.5%) from Rawalpindi, and 36 (31.5%) from Muzaffargarh. Phylogenetic analyses revealed that 18S rRNA sequences of H. canis from this study clustered in three clades with those of H. canis from previously published studies to the exclusion of all other Hepatozoon spp. included in the analysis. This study provides the first insight into H. canis from farm dogs in Pakistan. Furthermore, it lays a foundation for future studies of the parasite to assess the impact of canine hepatozoonosis in dogs from various agro-ecological zones in Pakistan where pet ownership of dogs is increasing.

PMID- 29455421 TI - Impact of baseline characteristics on outcomes of advanced HCC patients treated with sorafenib: a secondary analysis of a phase III study. AB - BACKGROUND: The current study aims to investigate the impact of baseline characteristics on the outcomes of sorafenib-treated advanced Hepatocellular carcinoma (HCC) patients in the setting of a clinical trial. METHODS: This is a secondary analysis of the comparator arm (sorafenib arm) of the NCT00699374 study which is a phase III multicenter study conducted between 2008 and 2010. The univariate probability of overall and progression-free survival was assessed among different patient subsets through Kaplan-Meier analysis and log-rank testing. Multivariate analysis of factors affecting overall and progression-free survival was then conducted through Cox regression analysis. RESULTS: All patients within the comparator (sorafenib) arm were included in the analysis (N = 544 patients). In multivariate analysis, prior hepatectomy (P = 0.028), prior locoregional treatment (P = 0.048), grade 1 ALBI score (P < 0.001), ECOG performance score of 0 (P < 0.001), BMI >= 25 (P = 0.026), AFP < 200 (P = 0.001), and no extra-hepatic spread (P = 0.007) were associated with better overall survival. Likewise, in multivariate analysis, non-Asian race (P = 0.004), grade 1 ALBI score (P = 0.001), ECOG performance score of 0 (P = 0.006), and no extra hepatic spread (P = 0.005) were associated with better progression-free survival. Moreover, development of high-grade hand-foot skin reaction was associated with a statistically significant improvement in overall survival (P = 0.003), which was further confirmed in a multivariate analysis adjusted for other relevant baseline factors (P = 0.002). CONCLUSION: Within a cohort of highly selected advanced HCC patients, baseline patient-, liver-, and disease-centered variables play an important role in predicting patient outcomes. This information is important in terms of therapeutic decision-making and patient counseling. PMID- 29455423 TI - Assessment of cerebral microbleeds by susceptibility-weighted imaging at 3T in patients with end-stage organ failure. AB - PURPOSE: Cerebral microbleeds (CMBs) are small rounded lesions representing cerebral hemosiderin deposits surrounded by macrophages that results from previous microhemorrhages. The aim of this study was to review the distribution of cerebral microbleeds in patients with end-stage organ failure and their association with specific end-stage organ failure risk factors. MATERIALS AND METHODS: Between August 2015 and June 2017, we evaluated 15 patients, 9 males, and 6 females, (mean age 65.5 years). Patients population was subdivided into three groups according to the organ failure: (a) chronic kidney failure (n = 8), (b) restrictive cardiomyopathy undergoing heart transplantation (n = 1), and (c) end-stage liver failure undergoing liver transplantation (n = 6). The MR exams were performed on a 3T MR unit and the SWI sequence was used for the detection of CMBs. CMBs were subdivided in supratentorial lobar distributed, supratentorial non-lobar distributed, and infratentorial distributed. RESULTS: A total of 91 microbleeds were observed in 15 patients. Fifty-nine CMBs lesions (64.8%) had supratentorial lobar distribution, 17 CMBs lesions (18.8%) had supratentorial non lobar distribution and the remaining 15 CMBs lesions (16.4%) were infratentorial distributed. An overall predominance of supratentorial multiple lobar localizations was found in all types of end-stage organ failure. The presence of CMBs was significantly correlated with age, hypertension, and specific end-stage organ failure risk factors (p < 0.001). CONCLUSIONS: CMBs are mostly founded in supratentorial lobar localization in end-stage organ failure. The improved detection of CMBs with SWI sequences may contribute to a more accurate identification of patients with cerebral risk factors to prevent complications during or after the organ transplantation. PMID- 29455424 TI - Hypo-fractionated stereotactic radiation therapy for lung malignancies by means of helical tomotherapy: report of feasibility by a single-center experience. AB - BACKGROUND: Several experiences in the literature report SBRT as an effective treatment option for medically inoperable early stage non-small cell lung cancer (NSCLC) and oligometastatic disease. The optimal fractionation schedules and total dose remain controversial. In this study, we evaluated the safety in terms of toxicity and efficacy of using of 8-10 fractions schedules with Helical Tomotherapy (HT) for primary and metastatic lung lesions. METHODS: Between March 2014 and May 2016, a total of 39 patients (median age 72 years, range 26-91) were treated with HT-SBRT for malignant lung lesions: 22 patients with early stage NSCLC, 17 with oligometastases. Patients received 8-10 fractions with lower daily dose for central and ultracentral lesions. Treatment-related toxicity was evaluated using CTCAE v 4.0 scale. Local control (LC), overall survival (OS) and toxicity rates were prospectively collected. RESULTS: Median duration of RT was 15 days (range 10-26 days) and no interruption occurred. With a median follow-up of 13 months (range 3-29), we reported one G2 pneumonitis (2.6%) and one G2 chest pain (2.6%); no >= G2 esophagitis was registered. Actuarial local control rate was 95.5% both at 12 and 24 months for early stage NSCLC and 92.9% both at 12 and 24 months for metastatic patients. OS rate was 94.4 and 92.3% at 1 year, and 94.4 and 83.9% at 2 years in primary and metastatic group, respectively. CONCLUSIONS: The use of 8-10 fractions schedule HT-SBRT for lung malignancies results in high LC and OS rates with minimal toxicities reported. PMID- 29455425 TI - The risk of type 2 diabetes mellitus according to the categories of body mass index: the Korean Genome and Epidemiology Study (KoGES). AB - AIMS: Obesity is an established risk factor for type 2 diabetes mellitus (T2DM). However, there is limited information on the pattern of relationship between the risk for T2DM and body mass index (BMI) categories including underweight and overweight. Thus, this study was to evaluate the risk of T2DM according to BMI categories defined by Asian-specific cutoff of BMI. METHODS: 7660 non-diabetic Koreans were grouped into five BMI categories (underweight, normal, overweight, obese and severe obese) defined by Asian-specific cutoff of BMI and followed up for 10 years to monitor the development of T2DM. With a reference of normal BMI group, Cox proportional hazards assumption was used to calculate hazard ratios (HRs) and their 95% confidence intervals for T2DM in five groups. Subgroup analysis was conducted by gender and age (40-59 years and 60-69 years). RESULTS: Baseline mean value of metabolic factors like fasting glucose, HOMA-IR, total cholesterol and the proportion of impaired fasting glucose increased proportionally to the level of BMI categories. Underweight group had the higher proportion of impaired glucose tolerance than normal and overweight group. In all subgroups, underweight, overweight, obese and severe obese group had the higher HRs for T2DM than normal group, but statistical significance was only found in overweight, obese and severe obese group. CONCLUSIONS: The risk of T2DM tends to increase proportionally to the level of BMI categories from overweight to severe obese group. Further studies should be considered to identify the incidental relationship between underweight and T2DM. PMID- 29455426 TI - Work-loss years among people diagnosed with diabetes: a reappraisal from a life course perspective. AB - AIMS: Early exit from the workforce has been proposed to be one of the unfavorable consequences of diabetes. We examined whether early exit from the workforce differed between persons who were and were not diagnosed with diabetes during their work career. METHODS: The cohort included 12,726 individuals of the Helsinki Birth Cohort Study, born between 1934 and 1944. Using data from nationwide registers, the cohort was followed up from early adulthood until they transitioned into retirement or died. Work-loss years were estimated using the restricted mean work years method. RESULTS: During a follow-up of 382,328 person years for men and 349 894 for women, 36.8% transitioned into old age pension and 63.2% exited workforce early. Among men, 40.5% of those with and 32.8% of those without diabetes transitioned into old age pension (p=0.003). The corresponding numbers for women were 48.6% and 40.4% (p = 0.013), respectively. Mean age at exit from the workforce was 60.1 (95% confidence interval [CI], 59.6 to 60.7) years among men with diabetes and 57.6 (95% CI, 57.2 to 58.0) years among men without diabetes (p = 0.016). Among women, corresponding ages were 61.4 (95% CI, 60.8 to 61.9) years for those with diabetes and 59.5 (95% CI, 59.3 to 59.7) years for those without diabetes (p < 0.001). The difference in mean restricted work loss years according to diabetes was 2.5 (95% CI 0.5 to 4.6) for men and 1.9 (95% CI 1.0 to 2.8) for women. CONCLUSION: Among individuals followed up throughout their work career, those with a diabetes diagnosis exited the workforce approximately two years later compared to those without diabetes. PMID- 29455427 TI - Variation in cardiac markers and electrocardiographic alterations in young calves naturally infected with bovine tropical theileriosis. AB - The present study was designed to assess the deleterious effects of bovine tropical theileriosis on the cardiovascular system and the consequent myocardial involvement in young calves. Myocardial effects in parasitic diseases are often neglected. Hemolytic anemia, associated secondary hypoxia, and vasculitis are cardinal features of bovine theileriosis. In the present study, electrocardiogram (ECG) alongside serum cardiac troponin I (cTnI) and creatinine phosphokinase myocardial band (CPK-MB) concentrations were analyzed in infected, treated, and control groups of young calves. Non-significant alterations were noticed in ECG. However, certain signs like sinus tachycardia, first-degree AV block, atrial premature complex, left atrial hypertrophy, and right atrial hypertrophy were found on consistent basis in infected calves. A significant increase in the serum concentration levels of cTnI and CPK-MB was noticed in infected calves followed by significant fall in both these biomarkers post treatment. cTnI and CPK-MB can definitely be used as myocardial markers in theileriosis-affected animals. PMID- 29455428 TI - Potential of feeding beef cattle with whole corn crop silage and rice straw in Malaysia. AB - The potential of using whole corn crop silage and rice straw as an alternative feed for the beef cattle based on the intake and growth performance were evaluated. Using randomised completely block design, nine adult Mafriwal cattle were blocked intro three groups and treated with three different forage diets supplemented with 20% pelleted palm kernel cake on dry matter basis. The treatments were 100% rice straw (RS), 100% corn silage (CS) and an equal mixture of rice straw and corn silage (MIX) fed ad libitum. The animals were housed in individual pens, and the feeding trial was conducted for 12 weeks with 2 weeks of adaptation period. The results showed that CS had the best feed nutritive composition with the lowest concentration of highly indigestible fibre and the highest concentration of organic matter and energy. The CS also had the highest intake, and the corn silage inclusion in MIX managed to improve the intake on par with CS in terms of the dry matter intake of body weight (DMI of BW), voluntary intake (VI) and crude protein (CP) intake. Cattle fed with CS gave the highest and most stable BW gain with an average daily gain (ADG) of 808 g/day rivalling cross-bred cattle fed with high amount of concentrates. The all straw diet (RS) supplemented with PKC recorded a positive ADG of 133 g/day while the MIX gave 383 g/day matching total Napier grass diet. PMID- 29455429 TI - Predictive Performance of Physiologically-Based Pharmacokinetic Models in Predicting Drug-Drug Interactions Involving Enzyme Modulation. AB - BACKGROUND: Physiologically-based pharmacokinetic (PBPK) modeling in predicting metabolic drug-drug interactions (mDDIs) is routinely used in drug development. Currently, the US FDA endorses the use of PBPK to potentially support dosing recommendations for investigational drugs as enzyme substrates of mDDIs, and to inform a lack of mDDIs for investigational drugs as enzyme modulators. METHODS: We systematically evaluated the performance of PBPK modeling in predicting mDDIs published in the literature. Models developed to assess both investigational drugs as enzyme substrates (Groups 1 and 2, as being inhibited and induced, respectively) or enzyme modulators (Groups 3 and 4, as inhibitors and inducers, respectively) were evaluated. Predicted ratios of the area under the curve (AUCRs) and/or maximum plasma concentration (CmaxRs) with and without comedication were compared with the observed ratios. RESULTS: For Groups 1, 2, 3, and 4, 62, 50, 44, and 43% of model-predicted AUCRs, respectively, were within a predefined threshold of 1.25-fold of observed values (0.8-1.25x). When the threshold was widened to twofold, the values increased to 100, 80, 81, and 86% (0.5-2.0x). For Groups 3 and 4, prediction for mDDI liability (the existence or lack of mDDIs) using PBPK appears to be satisfactory. CONCLUSION: Our analysis supports the FDA's current recommendations on the use of PBPK to predict mDDIs. PMID- 29455430 TI - Existential Meaning of Patients with Chronic Facial Pain. AB - Coping strategies are necessary to deal with pain, one of the most disabling conditions. Treatments are often refractory, and the elaboration of existential meaning is necessary to live with residual pain. The objective of this study was to discuss the relevance of the meaning of life in coping with refractory chronic neuropathic facial pain according to singular cases. Each patient is unique and needs a singular approach to understand and treat the pain phenomenon. Self transcendence, existential issues and philosophical values are central concepts to assess chronic conditions and should be highlighted in medical practice these days. PMID- 29455431 TI - Menstrual phase and the vascular response to acute resistance exercise. AB - INTRODUCTION: Aerobic exercise has a favorable effect on systemic vascular function, reducing both central (large elastic artery) and peripheral (smaller muscular artery) stiffness. The effects of resistance exercise (RE) on arterial stiffness are more complex. Acute RE increases central artery stiffness while decreasing peripheral stiffness. To date, the majority of studies have been performed in predominantly male participants. PURPOSE: To examine the effect of acute RE on central and peripheral arterial stiffnesses in women, a secondary purpose was to explore the influence of cyclic changes in estrogen status across the menstrual cycle on the arterial response to acute RE. METHODS: 18 healthy women [28 +/- 7 years, body mass index (BMI) 22.6 +/- 2.9 kg/m2] completed an acute RE bout during the early follicular and the early luteal phase of their menstrual cycle. Salivary 17beta-Estradiol concentration was measured during each phase, using a passive drool technique. Pulse-wave velocity (PWV) was obtained from the carotid-femoral and carotid-radial pulse sites to measure central and peripheral stiffness, respectively, using applanation tonometry. PWV was measured at rest, immediately, 10, 20, and 30 min post-RE. RESULTS: 17beta-Estradiol concentration was significantly lower in the early follicular vs. the early luteal phase of the menstrual cycle (1.78 +/- 0.51 vs. 2.40 +/- 0.26 pg/ml, p = 0.01). Central PWV significantly increased (p < 0.05) and peripheral PWV significantly decreased (p < 0.05) post-RE in both the early follicular and early luteal phases. No phase-by-time interaction was detected for either vascular segment (p > 0.05). CONCLUSION: Women experience increases in central arterial stiffness and reductions in peripheral arterial stiffness following acute RE. Menstrual cycle phase may not influence changes in arterial stiffness in response to acute RE. PMID- 29455432 TI - Serum miRNA-27a and miRNA-18b as potential predictive biomarkers of hepatitis C virus-associated hepatocellular carcinoma. AB - Hepatitis C virus (HCV) infection remains the main risk factor for chronic hepatitis (CHC), liver cirrhosis, and hepatocellular carcinoma (HCC). Changes in microRNA (miRNA) profiles can be associated with HCV infection and may either favor or inhibit the virus and/or its complication. Moreover, miRNAs have emerged as key regulators of various cancers including HCC. The aim of this work was to investigate the potentail role of miRNA-27a and miRNA-18b expression levels as non-invasive predictive biomarkers of hepatitis C virus-associated HCC. Furthermore, we aimed to explore potential association of these miRNAs expressions with HCC clinicopathological features' in Egyptian cases. This case control study included 200 participants [60 CHC patients, 39 post-HCV cirrhosis patients, 51 HCC cases], and 50 healthy volunteers. The serum miRNA-27a and miRNA 18b expression profiles were measured using quantitative real time-polymerase chain reaction (qRT-PCR). miRNA-27a and miRNA-18b expression levels were significantly increased in post-hepatitis C cirrhosis cases compared to control and CHC groups. In HCC group, only miRNA-27a expression levels were significantly increased. Moreover, miRNA-27a and miRNA-18b expression levels were positively correlated with distant metastasis, Child-Pugh grade, and lymph node metastasis. Logistic regression analysis revealed that miRNA-27a expression was an independent predictor of cirrhosis among CHC. Receiver operating characteristic (ROC) analyses showed that miRNA-27a and miRNA-18b expression levels were useful biomarkers discriminating cirrhosis from CHC (AUC were 0.672 and 0.487, respectively), and in differentiating HCC from post-hepatitis C cirrhosis (AUC were 0.897 and 0.723, respectively). By combined ROC analysis, power of miRNA-27a and miRNA-18b expression levels as discriminator between HCC from post-hepatitis C cirrhosis was high (AUC = 0.0.821). Serum microRNA-27a and miRNA-18b expression levels are promising diagnostic and non-invasive biomarkers of CHC, post-CHC cirrhosis, and HCC. PMID- 29455433 TI - Intracrine action of angiotensin II in mesangial cells: subcellular distribution of angiotensin II receptor subtypes AT1 and AT2. AB - Biological effects of angiotensin II (AngII) such as regulation of AngII target genes may be triggered by interaction of AngII with intracellular AngII receptor types 1 and 2 (AT1 and AT2), defined as intracrine response. The aim of this study was to examine the presence of AT1 and AT2 receptors in nuclear membrane of human mesangial cells (HMCs) and evaluate the possible biological effects mediated by intracellular AT1 through an intracrine mechanism. Subcellular distribution of AT1 and AT2 was evaluated by immunofluorescence and by western blot in isolated nuclear extract. Endogenous intracellular synthesis of AngII was stimulated by high glucose (HG). Effects of HG were analyzed in the presence of candesartan, which prevents AngII internalization. Both receptors were found in nuclear membrane. Fluorescein isothiocyanate (FITC)-labeled AngII added to isolated nuclei produced a fluorescence that was reduced in the presence of losartan or PD-123319 and quenched in the presence of both inhibitors simultaneously. HG induced overexpression of fibronectin and increased cell proliferation in the presence of candesartan, indicating an intracrine action of AngII induced by HG. Results showed the presence of nuclear receptors in HMCs that can be activated by AngII through an intracrine response independent of cytoplasmic membrane AngII receptors. PMID- 29455434 TI - Elucidating post-translational regulation of mouse CREB3 in Neuro2a cells. AB - CREB3 is an ER membrane-bound transcription factor; however, post-translational regulation of CREB3, including expression, processing, and activation, is not fully characterized. We therefore constructed several types of mouse CREB3 expression genes and elucidated their expression in Neuro2a cells by treatment with stimuli and co-transfection with genes associated with ER-Golgi homeostasis, such as mutant Sar1 [H79G], GRP78, and KDEL receptor 1 (KDELR1). Interestingly, treatment of Neuro2a cells expressing Flag-tagged full-length CREB3 with monensin and nigericin induced the expression of the approximately 50 kDa N-terminal fragment; however, its cleavage was not parallel to the levels of GADD153 and LC3 II. Co-transfection of full-length CREB3 together with Sar1 [H79G], GRP78, or KDELR1 showed that only Sar1 [H79G] induced expression of the cleaved form, and KDELR1 dramatically decreased the expression of the full-length form. Accordingly, Sar1 [H79G]- and KDELR1-overexpression influenced GAL4-CREB3 dependent luciferase activities. To understand the activation of CREB3 under more pathophysiological conditions, we focused on the effect of metal ions on CREB3 cleavage in Neuro2a cells. Among the six metal ions we tested, only copper ion stabilized full-length CREB3 expression. Copper ion also increased its N-terminal form and GAL4-CREB3-dependent luciferase activity, which was accompanied by the increase in the ubiquitinated proteins in Neuro2a cells. Taken together, CREB3 expression is regulated by multiple ER-Golgi resident factors in a post translational manner, but its processing is not directly associated with ER stress and autophagic dysfunction. This finding is especially true for the unique action of the copper ion on CREB3 stabilization and processing in parallel to aberration of ubiquitin-proteasome system, which might provide new insights into understanding the mechanisms of intractable disorders. PMID- 29455435 TI - DNA methylation regulated microRNAs in HPV-16-induced head and neck squamous cell carcinoma (HNSCC). AB - INTRODUCTION: Epigenetic modifications have been reported to play an important role in regulating gene expression and these modifications become critical when they have a role in controlling another important layer of epigenetic regulation namely microRNAs. In the present study, we have identified the microRNAs that may be regulated by promoter DNA methylation and histone acetylation in Human papilloma virus-positive head and neck squamous cell carcinoma. METHODOLOGY: HPV negative cell line (UPCI:SCC-116) and HPV-16 +ve cell line (UPCI:SCC-090) were treated with methylation inhibitor (5-aza-2'-deoxycytidine, AZA) and acetylation inhibitor (Trichostatin-A, TSA), followed by micro-array analysis. The differentially expressed miRNAs were validated in control (n = 10), HPV-16 +ve (n = 30), and HPV -ve (n = 30) HNC, TCGA (n = 529) tissue samples, and two HPV -ve (SCC116 and Hacat) and two HPV +ve (SCC090 and SiHa) cell lines. Methylation specific PCR (MSP) and chromatin immunoprecipitation assay (CHIP) were performed to validate their regulation. In silico and in vitro analyses of identified miRNAs were done to study putative pathways they target and their possible role in carcinogenesis. RESULTS: Among 10 miRNAs specifically up-regulated in microarray analysis of AZA-treated SCC090 cells, we observed significantly decreased expression of hsa-miR-181c-5p, hsa-miR-132-5p, hsa-miR-658 in HPV +ve HNC cohort, TCGA tissue samples, and cell lines as compared to their HPV -ve counterpart, and their promoter region also possesses CpG islands. MSP and analysis of TCGA data (MethHC) revealed increased frequency of methylation at the promoter of hsa-miR-132-5p that is negatively correlated with its expression. In TSA-treated SCC090 cells, out of 7 miRNAs, two namely Hsa-miR-129-2-3p and Hsa miR-449a were found to be up-regulated as compared to HPV -ve cells. However, the levels of enrichment by anti-acetyl-H3 and anti-acetyl-H4 were significantly low in cell lines compared to respective controls and both were up-regulated in HPV +ve compared to HPV -ve TCGA tissue samples. In silico analysis revealed hsa-miR 132-5p targeted canonical beta-catenin/wnt pathway and modulation of down-stream genes of the pathway was observed on over-expression/inhibition of hsa-miR-132 5p. CONCLUSION: This study suggests the role of epigenetic modifications in regulating expression of miRNAs in HPV +ve HNSCC.

While this population is thought to experience an early onset of aging-related health conditions ("accelerated aging"), studies have not directly compared rates of geriatric conditions in this population to those found in the general population. The aims of this study were to compare the burden of geriatric conditions among older adults in jail to rates found in an age-matched nationally representative sample of community dwelling older adults. METHODS: This cross sectional study compared 238 older jail inmates age 55 or older to 6871 older adults in the national Health and Retirement Study (HRS). We used an age-adjusted analysis, accounting for the difference in age distributions between the two groups, to compare sociodemographics, chronic conditions, and geriatric conditions (functional, sensory, and mobility impairment). A second age-adjusted analysis compared those in jail to HRS participants in the lowest quintile of wealth. RESULTS: All geriatric conditions were significantly more common in jail based participants than in HRS participants overall and HRS participants in the lowest quintile of net worth. Jail-based participants (average age of 59) experienced four out of six geriatric conditions at rates similar to those found in HRS participants age 75 or older. CONCLUSIONS: Geriatric conditions are prevalent in older adults in jail at significantly younger ages than non incarcerated older adults suggesting that geriatric assessment and geriatric focused care are needed for older adults cycling through jail in their 50s and that correctional clinicians require knowledge about geriatric assessment and care. PMID- 29455437 TI - Live donor liver transplantation for acute liver failure: A single center experience. AB - INTRODUCTION: Acute liver failure (ALF) is an indication for emergency liver transplantation (LT). Although centers performing only deceased donor liver transplants (DDLT) have shown improved outcomes in this situation, they still have relatively long waiting lists. An alternative would be living donor liver transplantation (LDLT), which has shown equivalent outcomes in the elective situation but there is limited evidence of its results in ALF. AIM: The purpose of this study was to assess the outcomes in patients with ALF undergoing emergency LDLT in our center in Delhi, India. METHODS: We prospectively collected data on 479 patients who underwent LT in our hospital between January 2009 and December 2015 to evaluate the outcomes of those with ALF. The ALF patients were listed for transplantation after they met the Kings' College criteria and rapid evaluation was done following a protocol consisting of three phases. Patients with grade III/IV encephalopathy were put on mechanical ventilation. Data regarding their postoperative course, morbidity, and mortality were analyzed. RESULTS: Thirty-six (7.5%) out of the 479 patients underwent emergency LT for ALF. Their mean age was 27.5 years (range 4-59 years) and the male to female ratio of 2:3. Preoperative intubation was required in 15 of 25 patients who had encephalopathy. Wilson's disease was the most common cause of ALF in children while in adults, it was acute viral hepatitis. The time interval between listing and transplantation was a mean of 36 +/- 12.4 h. The mean graft to recipient weight ratio (GRWR) was 1.06 +/- 0.3. The recipients were extubated postoperatively after a mean period of 2.6 days and their mean ICU stay was 6.3 days. Postoperative infection was the most common complication and required upgradation of antifungal and antibiotic treatments. Neurological complications occurred in five patients. Thirty-one of 36 (86.1%) patients survived and progressive cerebral edema and sepsis were the most common causes of mortality. Patients who died had higher model for end-stage liver disease scores, longer cold ischemia time (CIT), and higher grades of encephalopathy (though 80% patients with encephalopathy survived). There was no donor mortality. At long term follow up of a median of 56 months, 29 (80.5%) of 36 patients were still alive. CONCLUSIONS: In our experience, LDLT is an alternative procedure to DDLT in patients with ALF and is associated with good outcomes even in patients with high grades of encephalopathy.

AB - Blood leucocytes segmentation in medical images is viewed as difficult process due to the variability of blood cells concerning their shape and size and the difficulty towards determining location of Blood Leucocytes. Physical analysis of blood tests to recognize leukocytes is tedious, time-consuming and liable to error because of the various morphological components of the cells. Segmentation of medical imagery has been considered as a difficult task because of complexity of images, and also due to the non-availability of leucocytes models which entirely captures the probable shapes in each structures and also incorporate cell overlapping, the expansive variety of the blood cells concerning their shape and size, various elements influencing the outer appearance of the blood leucocytes, and low Static Microscope Image disparity from extra issues outcoming about because of noise. We suggest a strategy towards segmentation of blood leucocytes using static microscope images which is a resultant of three prevailing systems of computer vision fiction: enhancing the image, Support vector machine for segmenting the image, and filtering out non ROI (region of interest) on the basis of Local binary patterns and texture features. Every one of these strategies are modified for blood leucocytes division issue, in this manner the subsequent techniques are very vigorous when compared with its individual segments. Eventually, we assess framework based by compare the outcome and manual division. The findings outcome from this study have shown a new approach that automatically segments the blood leucocytes and identify it from a static microscope images. Initially, the method uses a trainable segmentation procedure and trained support vector machine classifier to accurately identify the position of the ROI. After that, filtering out non ROI have proposed based on histogram analysis to avoid the non ROI and chose the right object. Finally, identify the blood leucocytes type using the texture feature. The performance of the foreseen approach has been tried in appearing differently in relation to the system against manual examination by a gynaecologist utilizing diverse scales. A total of 100 microscope images were used for the comparison, and the results showed that the proposed solution is a viable alternative to the manual segmentation method for accurately determining the ROI. We have evaluated the blood leucocytes identification using the ROI texture (LBP Feature). The identification accuracy in the technique used is about 95.3%., with 100 sensitivity and 91.66% specificity. PMID- 29455441 TI - A proactive transfer policy for critical patient flow management. AB - Hospital emergency departments are often overcrowded, resulting in long wait times and a public perception of poor attention. Delays in transferring patients needing further treatment increases emergency department congestion, has negative impacts on their health and may increase their mortality rates. A model built around a Markov decision process is proposed to improve the efficiency of patient flows between the emergency department and other hospital units. With each day divided into time periods, the formulation estimates bed demand for the next period as the basis for determining a proactive rather than reactive transfer decision policy. Due to the high dimensionality of the optimization problem involved, an approximate dynamic programming approach is used to derive an approximation of the optimal decision policy, which indicates that a certain number of beds should be kept free in the different units as a function of the next period demand estimate. Testing the model on two instances of different sizes demonstrates that the optimal number of patient transfers between units changes when the emergency patient arrival rate for transfer to other units changes at a single unit, but remains stable if the change is proportionally the same for all units. In a simulation using real data for a hospital in Chile, significant improvements are achieved by the model in key emergency department performance indicators such as patient wait times (reduction higher than 50%), patient capacity (21% increase) and queue abandonment (from 7% down to less than 1%). PMID- 29455442 TI - In Search of Executive Impairment in Pathological Gambling: A Neuropsychological Study on Non-treatment Seeking Gamblers. AB - Pathological gambling is characterized by a persisting maladaptive and recurrent behavior with severe social and psychological consequences. There is evidence of strong comorbidity with psychiatric manifestations as well as cognitive mainly involving executive functions. This study aimed to investigate impairment in executive functions and working memory, and personality traits in a sample of Greek gamblers. Twenty-four men involved in various gambling activities were recruited from ecological settings as probable pathological gamblers. They were assessed with a comprehensive neuropsychological battery involving several executive tasks, the Zuckerman-Kuhlman Personality Questionnaire, the Hospital Anxiety Depression Scale, and the Difficulties in Emotion Regulation Scale. An age- and education-level matched group of 21 men without history of habitual gambling served as controls. As a group, gamblers displayed significantly lower scores on indices of inhibition, decision making and self-reported emotional awareness, and scored higher on impulsivity/sensation seeking personality traits. Notably, gamblers scored similarly or significantly higher on measures of verbal and visuospatial working memory, cognitive flexibility, processing speed, verbal fluency, and sustained attention. Overall, we argue that gamblers do present with specific cognitive deficits, but there is no evidence for a generalized executive impairment, and further stress the importance of investigating cognitive, personality, and psychiatric aspects of gambling on the basis of an ecologically valid sampling. PMID- 29455443 TI - Narcissistic Implications in Gambling Disorder: The Mediating Role of Emotion Dysregulation. AB - Gambling Disorder (GD) is a complex psychopathology involving a numbers of cognitive, behavioral, emotional and neurobiological determinants. Previous research suggests that GD may frequently co-occur with Narcissistic Personality Disorder. However, there is still a lack of study investigating Pathological Narcissism (PN) in both its vulnerable and grandiose facets among clinical population. Moreover, emotional dysregulation is commonly thought to underlie GD albeit research on this topic remains poor. The present study aims to investigate the role of both vulnerable and grandiose narcissism in relation to GD as well as the mediator role played by emotion dysregulation in such link. We administered to a sample of addicted gamblers (n = 74) and a sample of heathy controls (n = 105), the South Oaks Gambling Screen (SOGS), the Pathological Narcissism Inventory (PNI) and the Difficulties in Emotion Regulation Scale (DERS). Differences across groups emerged on the scores obtained on the PNI and DERS. Moreover, we found positive associations between SOGS scores and both PNI and DERS. Also, strategic addicted gamblers showed higher levels of vulnerable narcissism compared to others. Finally, emotion dysregulation difficulties appeared to fully mediate the relationship between grandiose narcissism and GD severity. Grandiose and vulnerable narcissism appear important variables involved in GD. Also, emotion regulation deficits seem to account for GD and to explain the pathways by which grandiose narcissism leads to GD. Clinical implications and future directions are discussed.

AB - Persistent left superior vena cava (PLSVC) is one of the most common thoracic venous anomaly and rarely noticed, because it is asymptomatic. However, for nephrologists, it is frequent enough to be encountered while placing hemodialysis catheters through the jugular vein. We report the case of 66-year-old patient with PLSVC presenting intrinsic thrombosis formation 4 h after dialysis catheter placed. Dialysis catheter was placed in the left internal jugular vein without resistance and any complication. PLSVC was detected after dialysis catheter insertion. We decided to remove the catheter, because the patient has other veins in which the catheter can be placed. When it was removed 4 h after catheter placing, thrombus was recognized in the catheter lumen. Transesophageal echocardiography was performed and no thrombus formation was observed in the heart chamber. For patients with PLSVC, if there were other veins in which the catheter can be placed, catheter replacement should be considered. PMID- 29455445 TI - Adaptive reinventing: implicit bias and the co-construction of social change. AB - Emerging research on implicit bias recognition and management within health professions describes individually focused educational interventions without considering workplace influences. Workplace learning theories highlight how individual agency and workplace structures dynamically interact to produce change within individuals and learning environments. Promoting awareness of individual biases shaped by clinical learning environments may therefore represent a unique type of workplace learning. We sought to explore how individuals and the workplace learning environment interact once awareness of implicit biases are triggered within learners. In accordance with longitudinal case study methodology and informed by constructivist grounded theory, we conducted multiple longitudinal interviews with physician and nurse participants over 12 months. Our results suggest that implicit bias recognition provokes dissonance among participants leading to frustration, and critical questioning of workplace constraints. Once awareness is triggered, participants began reflecting on their biases and engaging in explicit behavioural changes that influenced the perception of structural changes within the learning environment itself. Collaboration, communication and role modeling within teams appeared to facilitate the process as individual and workplace affordances were gradually transformed. Our findings suggest a potential model for understanding how individual learners adaptively reinvent their role in response to disruptions in their learning environment. PMID- 29455446 TI - BIG2-ARF1-RhoA-mDia1 Signaling Regulates Dendritic Golgi Polarization in Hippocampal Neurons. AB - Proper dendrite development is essential for establishing neural circuitry, and Rho GTPases play key regulatory roles in this process. From mouse brain lysates, we identified Brefeldin A-inhibited guanine exchange factor 2 (BIG2) as a novel Rho GTPase regulatory protein involved in dendrite growth and maintenance. BIG2 was highly expressed during early development, and knockdown of the ARFGEF2 gene encoding BIG2 significantly reduced total dendrite length and the number of branches. Expression of the constitutively active ADP-ribosylation factor 1 ARF1 Q71L rescued the defective dendrite morphogenesis of ARFGEF2-null neurons, indicating that BIG2 controls dendrite growth and maintenance by activating ARF1. Moreover, BIG2 co-localizes with the Golgi apparatus and is required for Golgi deployment into major dendrites in cultured hippocampal neurons. Simultaneous overexpression of BIG2 and ARF1 activated RhoA, and treatment with the RhoA activator lysophosphatidic acid in neurons lacking BIG2 or ARF1 increased the number of cells with dendritic Golgi, suggesting that BIG2 and ARF1 activate RhoA to promote dendritic Golgi polarization. mDia1 was identified as a downstream effector of BIG2-ARF1-RhoA axis, mediating Golgi polarization and dendritic morphogenesis. Furthermore, in utero electroporation of ARFGEF2 shRNA into the embryonic mouse brain confirmed an in vivo role of BIG2 for Golgi deployment into the apical dendrite. Taken together, our results suggest that BIG2-ARF1-RhoA mDia1 signaling regulates dendritic Golgi polarization and dendrite growth and maintenance in hippocampal neurons. PMID- 29455447 TI - The continuum of breast cancer care and outcomes in the U.S. Military Health System: an analysis by benefit type and care source. AB - PURPOSE: This study investigates transition rates between breast cancer diagnosis, recurrence, and death by insurance benefit type and care source in U.S. Military Health System (MHS). METHODS: The MHS data repository and central cancer registry linked data were used to identify women aged 40-64 with histologically confirmed breast cancer between 2003 and 2007. Three-state continuous time Markov models were used to estimate transition rates and transition rate ratios (TRRs) by TRICARE benefit type (Prime or non-Prime) and care source (direct, purchased, or both), adjusted for demographic, tumor, and treatment variables. RESULTS: Analyses included 2668 women with transitions from diagnosis to recurrence (n = 832), recurrence to death (n = 79), and diagnosis to death without recurrence (n = 91). Compared to women with Prime within each care source, women with non-Prime using both care sources had higher transition rates (TRR 1.47, 95% CI 1.03, 2.10). Compared to those using direct care within each benefit type, women utilizing both care sources with non-Prime had higher transition rates (TRR 1.86, 95% CI 1.11, 3.13), while women with Prime utilizing purchased care had lower transition rates (TRR 0.82, 95% CI 0.68, 0.98). CONCLUSIONS: In the MHS, women with non-Prime benefit plans compared to Prime had higher transition rates along the breast cancer continuum among both care source users. Purchased care users had lower transition rates than direct care users among Prime beneficiaries. IMPLICATIONS FOR CANCER SURVIVORS: Benefit plan and care source may be associated with breast cancer progression. Further research is needed to demonstrate differences in survivorship.

PMID- 29455449 TI - Role of Exosomes Derived from miR-133b Modified MSCs in an Experimental Rat Model of Intracerebral Hemorrhage. AB - Intracerebral hemorrhage (ICH) has poor outcomes due to high mortality and morbidity, but until now, the effective treatments remain limited. MicroRNAs (miRNAs) are vital regulators of gene expression and demonstrated to be linked to the pathogenesis of various central nervous system (CNS) diseases. Exosomes are considered as cell-to-cell communication vectors and secreted largely by mesenchymal stromal cells (MSCs). The present study investigated the role of miR 133b delivered by exosomes secreted from MSCs to brain tissues in rats after ICH. An autologous arterial blood ICH model in adult male Sprague-Dawley (SD) rats was used in this study. At 72 h after transfection with miR-133b mimics in MSCs, miR 133b-modified MSC-derived exosomes were collected from medium of MSCs and then injected to rats via tail vein. The levels of miR-133b in secreted exosomes and brain tissues of rats in various groups and the levels of RhoA, phosphorylations of extracellular signal regulating kinase (ERK1/2), and cAMP response element binding protein (CREB) were detected by real-time PCR and western blot analysis, respectively. The effects of miR-133b on neuronal apoptosis and degeneration were respectively evaluated by TUNEL and fluoro-jade B staining. The miR-133b levels were reduced in brain tissues of rats at 24 h and peaked at 72 h after ICH. At 24 h after miR-133b-modified exosome administration, the level of miR-133b was significantly increased, while the apoptotic and neurodegenerative neurons were obviously reduced in brain tissues after ICH. The results of western blot analysis showed that miR-133b modified exosomes treatment remarkably suppressed RhoA expression and activated ERK1/2/CREB in brain tissues after ICH. Collectively, our investigation suggested that exosomes derived from miR-133b modified MSCs exhibited neuroprotective role for anti-apoptotic effect of miR 133b mediating RhoA and ERK1/2/CREB in rats after ICH. PMID- 29455451 TI - Both B-1a and B-1b cells exposed to Mycobacterium tuberculosis lipids differentiate into IgM antibody-secreting cells. AB - Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis. The cellular immune response to mycobacteria has been characterized extensively, but the antibody response remains underexplored. The present study aimed to examine whether host or bacterial phospholipids induce secretion of IgM, and specifically anti-phospholipid IgM, antibodies by B cells and to identify the responsible B cell subset. Here we show that peritoneal B cells responded to lipid antigens by secreting IgM antibodies. Specifically, stimulation with M. tuberculosis H37Rv total lipids resulted in significant induction of total and anti phosphatidylcholine IgM. Similarly, IgM antibody production increased significantly with stimulation by whole Mycobacterium bovis bacillus Calmette Guerin. The B-1 subset was the dominant source of IgM antibodies after exposure to cardiolipin. Both CD5+ B-1a and CD5- B-1b cell subsets secreted total IgM antibodies after exposure to M. tuberculosis H37Rv total lipids in vitro. Overall, our results suggest that the poly-reactive B-1 cell repertoire contributes to non-specific anti-phospholipid IgM antibody secretion in response to M. tuberculosis lipids.

AB - Mastocarpus stellatus and Chondrus crispus often co-occur in the lower intertidal of Northern Atlantic rocky shorelines. At our field site along the Maine coast (USA), Mastocarpus stellatus thalli possessed greater contents of proline when compared with thalli of Chondrus crispus. In addition, M. stellatus thalli acclimated to colder growth conditions in winter/early spring by increasing proline content several fold; no seasonal acclimation in proline content was observed in C. crispus. Proline accumulates in the tissues of a broad diversity of freezing-tolerant organisms and is among the most common cryoprotectant molecules. Thus, our observations provide a basis for the previously well documented greater freezing tolerance of Mastocarpus stellatus when compared with Chondrus crispus. PMID- 29455454 TI - Oxidative capacity varies along the length of healthy human tibialis anterior. AB - KEY POINTS: During exercise skeletal muscles use the energy buffer phosphocreatine. The post-exercise recovery of phosphocreatine is a measure of the oxidative capacity of muscles and is traditionally assessed by 31 P magnetic resonance spectroscopy of a large tissue region, assuming homogeneous energy metabolism. To test this assumption, we collected spatially resolved spectra along the length of human tibialis anterior using a home-built array of 31 P detection coils, and observed a striking gradient in the recovery rate of phosphocreatine, decreasing along the proximo-distal axis of the muscle. A similar gradient along this muscle was observed in signal changes recorded by 1 H muscle functional MRI. These findings identify intra-muscular variation in the physiology of muscles in action and highlight the importance of localized sampling for any methodology investigating oxidative metabolism of this, and potentially other muscles. ABSTRACT: The rate of phosphocreatine (PCr) recovery (kPCr ) after exercise, characterizing muscle oxidative capacity, is traditionally assessed with unlocalized 31 P magnetic resonance spectroscopy (MRS) using a single surface coil. However, because of intramuscular variation in fibre type and oxygen supply, kPCr may be non-uniform within muscles. We tested this along the length of the tibialis anterior (TA) muscle in 10 male volunteers. For this purpose, we employed a 3T MR system with a 31 P/1 H volume transmit coil combined with a home-built 31 P phased-array receive probe, consisting of five coil elements covering the TA muscle length. Mono-exponential kPCr was determined for all coil elements after 40 s of submaximal isometric dorsiflexion (SUBMAX) and incremental exercise to exhaustion (EXH). In addition, muscle functional MRI (1 H mfMRI) was performed using the volume coil after another 40 s of SUBMAX. A strong gradient in kPCr was observed along the TA (P < 0.001), being two times higher proximally vs. distally during SUBMAX and EXH. Statistical analysis showed that this gradient cannot be explained by pH variations. A similar gradient was seen in the slope of the initial post-exercise 1 H mfMRI signal change, which was higher proximally than distally in both the TA and the extensor digitorum longus (P < 0.001) and strongly correlated with kPCr . The pronounced differences along the TA in functional oxidative capacity identify regional variation in the physiological demand of this muscle during everyday activities and have implications for the bio-energetic assessment of interventions to modify its performance and of neuromuscular disorders involving the TA.

AB - Clownfishes (or anemonefishes) form an iconic group of coral reef fishes, principally known for their mutualistic interaction with sea anemones. They are characterized by particular life history traits, such as a complex social structure and mating system involving sequential hermaphroditism, coupled with an exceptionally long lifespan. Additionally, clownfishes are considered to be one of the rare groups to have experienced an adaptive radiation in the marine environment. Here, we assembled and annotated the first genome of a clownfish species, the tomato clownfish (Amphiprion frenatus). We obtained 17,801 assembled scaffolds, containing a total of 26,917 genes. The completeness of the assembly and annotation was satisfying, with 96.5% of the Actinopterygii Benchmarking Universal Single-Copy Orthologs (BUSCOs) being retrieved in A. frenatus assembly. The quality of the resulting assembly is comparable to other bony fish assemblies. This resource is valuable for advancing studies of the particular life history traits of clownfishes, as well as being useful for population genetic studies and the development of new phylogenetic markers. It will also open the way to comparative genomics. Indeed, future genomic comparison among closely related fishes may provide means to identify genes related to the unique adaptations to different sea anemone hosts, as well as better characterize the genomic signatures of an adaptive radiation. PMID- 29455458 TI - Diagnosis, presentation and initial severity of Autoimmune Hepatitis (AIH) in patients attending 28 hospitals in the UK. AB - BACKGROUND & AIMS: There is limited information regarding patients with AIH outside relatively few large centres. We describe here the presenting features of patients with AIH, collected as part of an audit involving 28 UK hospitals. METHODS: Patients (incident since 1/1/2007 or prevalent since 1/1/2000) were >=18 years and either met 1999 International AIH Group (IAIHG) diagnostic criteria (n = 1164), or received immunosuppressive therapy for clinically diagnosed AIH (n = 103). RESULTS: Of 1267 patients (80% women, 91% Caucasian, age (median(range)) 55(8-86) years, 0.5% had acute viral hepatitis (CMV/EBV/HEV); 2% were taking Nitrofurantoin and 0.7% Khat. Twenty-one percent had clinical decompensation and/or a MELD score of >15. Time from first abnormal liver tests to diagnosis was >=1 year in 19% and was longer in jaundiced vs non-jaundiced patients. HBV and HCV serology were undocumented in 4%, serum immunoglobulins in 31% and autoantibodies in 11%-27%. When documented, >=1 antibody was present in 83%. LKM 1-positive and autoantibody-negative patients had more severe disease. Histological cirrhosis was reported in 23%, interface hepatitis 88%, predominant lymphocytes/plasma cells 75%, rosettes 19% and emperipolesis 0.4%. Only 65% of those meeting 1999 IAIHG criteria also met simplified IAIHG criteria. University Hospitals compared to District General Hospitals, were more likely to report histological features of AIH. CONCLUSIONS: This cohort from across the UK is older than other multicentre AIH cohorts. One-fifth had decompensation or MELD >15. Diagnosis was delayed in 19%, diagnostic testing was incomplete in one-third and rosettes and emperipolesis were infrequently reported. PMID- 29455460 TI - One-year longitudinal study found a bidirectional relationship between physical activity and sleep disturbance in teenage Estonian girls. AB - AIM: Studies have shown that physical activity (PA) declines during adolescence, especially among girls. We examined the relationship between changes in PA and sleep disturbance over the school year, including any bidirectional relationship between these two factors. METHODS: This longitudinal study focused on teenage girls who had a mean age of 13.2 +/- 0.2 years at baseline and were drawn from five randomly selected schools in the city of Tartu, Estonia. Sleep disturbance and PA were subjectively assessed using the self-reported 3-Day Physical Activity Recall and the Insomnia Severity Index, at four intervals throughout the school year. Latent growth curve analyses were used to evaluate longitudinal and bidirectional associations between PA and sleep disturbance. RESULTS: Assessments were carried out at three-monthly intervals from September 2015 to June 2016. Sleep disturbance increased and PA decreased over the school year. At baseline, higher PA was related to lower sleep disturbance. Changes in PA corresponded with changes in sleep disturbance. A negative bidirectional relationship between sleep disturbance and PA over time was also found. CONCLUSION: These results suggest that increasing PA may be an effective strategy for improving the quality of sleep in girls during early adolescence. PMID- 29455461 TI - Population density mediates the interaction between pre- and postmating sexual selection. AB - When females mate with more than one male, sexual selection acts both before and after mating. The interaction between pre- and postmating episodes of selection is expected to be context dependent, but few studies have investigated how total sexual selection changes under different ecological conditions. We examined how population density mediates the interaction between pre- and postmating sexual selection by establishing replicate populations of the horned dung beetle Onthophagus taurus at low, medium, and high densities, and then using microsatellite-based parentage analyses to measure male fitness. We found that mating success and fertilization success were positively correlated at all three densities, but the strength of the correlation decreased with increasing density. We also found a shift from negative to positive linear selection on testes mass as density increased, and opposing selection on weapons and testes at high densities. These patterns suggest that the importance of postmating processes increases with increasing population density, which reduces the selective advantage of weapons for premating contest competition, and increases the selective advantage of large ejaculates for postmating sperm competition. We expect that density-dependent selection on testes mass has contributed to the phenotypic variation observed between natural populations of O. taurus that differ in density.

AB - Different second-generation sequencing technologies may have taxon-specific biases when DNA metabarcoding prey in predator faeces. Our major objective was to examine differences in prey recovery from bat guano across two different sequencing workflows using the same faecal DNA extracts. We compared results between the Ion Torrent PGM and the Illumina MiSeq with similar library preparations and the same analysis pipeline. We focus on repeatability and provide an R Notebook in an effort towards transparency for future methodological improvements. Full documentation of each step enhances the accessibility of our analysis pipeline. We tagged DNA from insectivorous bat faecal samples, targeted the arthropod cytochrome c oxidase I minibarcode region and sequenced the product on both second-generation sequencing platforms. We developed an analysis pipeline with a high operational taxonomic unit (OTU) clustering threshold (i.e., >=98.5%) followed by copy number filtering to avoid merging rare but genetically similar prey into the same OTUs. With this workflow, we detected 297 unique prey taxa, of which 74% were identified at the species level. Of these, 104 (35%) prey OTUs were detected by both platforms, 176 (59%) OTUs were detected by the Illumina MiSeq system only, and 17 (6%) OTUs were detected using the Ion Torrent system only. Costs were similar between platforms but the Illumina MiSeq recovered six times more reads and four additional insect orders than did Ion Torrent. The considerations we outline are particularly important for long-term ecological monitoring; a more standardized approach will facilitate comparisons between studies and allow faster recognition of changes within ecological communities. PMID- 29455465 TI - Insulin-like growth factor 2: a poor prognostic biomarker linked to racial disparity in women with uterine carcinosarcoma. AB - The objective of this study was to investigate the relationship of insulin-like growth factor 2 (IGF2) expression and survival in women with uterine carcinosarcoma (UCS). Insulin-like growth factor 2 protein expression was determined by immunohistochemical staining of tumor tissues from 103 patients with UCS. The H-score (product of staining intensity and percentage positive cells) was quantified for the epithelial cytoplasmic (EC), epithelial nuclear (EN), and malignant stromal compartments. Multivariable Cox proportional hazard regression models were used to examine the relationship of IGF2 levels with progression-free survival (PFS) and overall survival (OS). Adjusting for stage, race, and adjuvant therapy, PFS and OS were reduced in patients with high IGF2 (H score >= median) in the EC and EN compartments. Black race was independently associated with reduced PFS and OS in patients with early-stage disease, and IGF2 levels in the EC were higher in black than in white patients (P = 0.02, Wilcoxon test). In a race-stratified multivariable analysis, high IGF2 in the epithelial compartments more than doubled the risk of death in black women; HR = 2.43 (95% CI: 1.18-5.01, P = 0.02) for high IGF2 in the EC; and HR = 2.34 (95% CI: 1.25 4.39, P = 0.008) for high IGF2 in the EN. In conclusion, high tumor IGF2 expression is an independent risk factor for reduced PFS and OS in UCS. Black women have elevated tumor IGF2 compared with white women, and decreased survival associated with high IGF2. These findings identify IGF2 as a candidate biomarker for survival linked to racial disparity in women with UCS. PMID- 29455467 TI - Predicting reintroduction outcomes for highly vulnerable species that do not currently coexist with their key threats. AB - Predicting reintroduction outcomes before populations are released is inherently challenging. It becomes even more difficult when the species being considered for reintroduction no longer coexists with the key threats limiting its distribution. However, data from other species facing the same threats can be used to make predictions under these circumstances. We used an integrated Bayesian modeling approach to predict growth of a reintroduced population at a range of predator densities when no data are available for the species in the presence of that predator. North Island Saddlebacks (Philesturnus rufusater) were extirpated from mainland New Zealand by exotic mammalian predators, particularly ship rats (black rats [Rattus rattus]) but are now being considered for reintroduction to sites with intensive predator control. We initially modeled data from previous saddleback reintroductions to predator-free sites to predict population growth at a new predator-free site while accounting for random variation in vital rates among sites. We then predicted population growth at different rat-tracking rates (an index of rat density) by incorporating a previously modeled relationship between rat-tracking and vital rates of another predator-sensitive species, the North Island Robin (Petroica longipes), and accounted for greater vulnerability of saddlebacks to rat predation based on information on historical declines of both species. The results allowed population growth to be predicted as a function of management effort while accounting for uncertainty, which means formal decision analysis could be used to decide whether to proceed with a reintroduction. Similar approaches could be applied to other situations where data on the species of interest are limited and provide an alternative to decision making based solely on expert judgment. PMID- 29455466 TI - The effects of interleukin-33 on airways collagen deposition and matrix metalloproteinase expression in a murine surrogate of asthma. AB - It has been suggested that interleukin-33 (IL-33) plays an important role in the pathogenesis of asthma through a variety of pathways, but its role in airways fibrosis in asthma has not been fully elucidated. In the present study we evaluated changes in the expression of extracellular matrix proteins (ECMs) as well as matrix metalloproteinases (MMPs) and their inhibitors (TIMPs) in an IL-33 induced, antigen-independent murine surrogate of asthma as well as a conventional surrogate employing per-nasal challenge of mice previously sensitized to produce an IgE response to ovalbumin (OVA). In addition, in in vitro experiments we explored the direct effects of IL-33 on the proliferation and function of murine fibroblasts. Per-nasal administration of IL-33 alone was sufficient to induce airways deposition of ECMs, including collagens I, III, V and fibronectin, to a degree comparable with that observed in the OVA-sensitized and challenged mice. These changes were associated with a local imbalance between the expression of extracellular MMPs and TIMPs. Per-nasal challenge of mice with IL-33 also induced elevated airways expression of connective tissue growth factor and fibroblast growth factor receptor 4, two key facilitators of local fibrosis, again to a degree compatible with that observed in OVA-sensitized and challenged mice. Deletion of the ST2 gene, which encodes the IL-33 receptor, abrogated these fibrotic changes in the airways in the OVA surrogate. In vitro, IL-33 significantly increased the proliferation and expression of collagen III by murine lung fibroblasts. These data suggest that direct exposure of murine airways to IL-33 is able to induce local fibrotic changes, at least partially through effects of signalling through the IL-33/ST2 axis on fibroblast function and local expression of MMPs and their inhibitors, and other fibrosis-related proteins. PMID- 29455469 TI - Insect herbivory and plant adaptation in an early successional community. AB - To address the role of insect herbivores in adaptation of plant populations and the persistence of selection through succession, we manipulated herbivory in a long-term field experiment. We suppressed insects in half of 16 plots over nine years and examined the genotypic structure and chemical defense of common dandelion (Taraxacum officinale), a naturally colonizing perennial apomictic plant. Insect suppression doubled dandelion abundance in the first few years, but had negligible effects thereafter. Using microsatellite DNA markers, we genotyped >2500 plants and demonstrate that insect suppression altered the genotypic composition of plots in both sampling years. Phenotypic and genotypic estimates of defensive terpenes and phenolics from the field plots allowed us to infer phenotypic plasticity and the response of dandelion populations to insect mediated natural selection. The effects of insect suppression on plant chemistry were, indeed, driven both by plasticity and plant genotypic identity. In particular, di-phenolic inositol esters were more abundant in plots exposed to herbivory (due to the genotypic composition of the plots) and were also induced in response to herbivory. This field experiment thus demonstrates evolutionary sorting of plant genotypes in response to insect herbivores that was in same direction as the plastic defensive response within genotypes. PMID- 29455468 TI - Implications of macrophage polarization in autoimmunity. AB - Macrophages are extremely heterogeneous and plastic cells with an important role not only in physiological conditions, but also during inflammation (both for initiation and resolution). In the early 1990s, two different phenotypes of macrophages were described: one of them called classically activated (or inflammatory) macrophages (M1) and the other alternatively activated (or wound healing) macrophages (M2). Currently, it is known that functional polarization of macrophages into only two groups is an over-simplified description of macrophage heterogeneity and plasticity; indeed, it is necessary to consider a continuum of functional states. Overall, the current available data indicate that macrophage polarization is a multifactorial process in which a huge number of factors can be involved producing different activation scenarios. Once a macrophage adopts a phenotype, it still retains the ability to continue changing in response to new environmental influences. The reversibility of polarization has a critical therapeutic value, especially in diseases in which an M1/M2 imbalance plays a pathogenic role. In this review, we assess the high plasticity of macrophages and their potential to be exploited to reduce chronic/detrimental inflammation. On the whole, the evidence detailed in this review underscores macrophage polarization as a target of interest for immunotherapy. PMID- 29455470 TI - Separation of positional isomers of nine 2-phenethylamine-derived designer drugs by liquid chromatography-tandem mass spectrometry. AB - The synthesis of positional isomers of designer drugs is a common way of bypassing legal restrictions. For forensic case work, and especially for the legal assessment of cases, there is a need for screening methods capable of the unequivocal identification of positional isomers. The presented liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS) method facilitates separation of positional isomers of 9 2-phenethylamine-derived designer drugs in different matrices including seized materials, hair, serum, and urine specimens. Chromatographic separation was achieved on a biphenyl phase using gradient elution with a total runtime of 26 minutes. The limit of detection was 25 pg/mg for hair samples and ranged from 0.1 ng/mL to 0.5 ng/mL for serum and from 0.2 ng/mL to 1.2 ng/mL for urine samples. The method proved to be selective and sensitive and showed good chromatographic resolution (R >= 1.2). The method was successfully applied to routine case samples. PMID- 29455471 TI - World traumatic dental injury prevalence and incidence, a meta-analysis-One billion living people have had traumatic dental injuries. AB - Traumatic dental injuries (TDIs) account for a considerable proportion of bodily injuries. Nevertheless, global TDI frequency is unknown, probably because TDI diagnosis is not standardized. This study estimated world TDI frequency. A literature search (publication years 1996-2016) was aimed at covering as many countries, communities, ethnic groups as possible, thus achieving high generalizability. In particular, non-specific keywords, no language restrictions, and large databanks were used. Observational studies reporting proportions of individuals with at least one TDI (prevalence) and who developed TDI (incidence rate) were considered. Prevalence rates to permanent dentition, primary dentition and in 12-year-olds, incidence rate to any tooth for any age, male-to-female prevalence ratio (PR) in 12-year-olds, with 95% confidence intervals (95 CIs), were extracted/calculated. Study quality, Z-score distribution, funnel plot symmetry analysis, between-study heterogeneity, sensitivity, and subgroup analyses were performed. Selected primary studies were 102 (permanent dentition; 268 755 individuals; median age, 13.8 years), 46 (primary dentition; 59 436 individuals; median age, 3.4 years), 42 (12-year-olds; 33 829 individuals), 11 (incidence rate; 233 480 person-years; median age, 7.8 years), and 31 (PR; 16 003 males, 16 006 females). World TDI frequency resulted as follows: permanent dentition prevalence 15.2% (95 CI, 13.0%-17.4%); primary dentition prevalence 22.7% (95 CI, 17.3%-28.7%); 12-year-olds prevalence 18.1% (95 CI, 15.3%-21.0%); incidence rate, 2.82 (95 CI, 2.28%-3.42%) per 100 person-years; PR, 1.43 (95 CI, 1.34%-1.52%). Differences between WHO Regions were found. This study shows that more than one billion living people have had TDI. TDI is a neglected condition which could rank fifth if it was included in the list of the world's most frequent acute/chronic diseases and injuries. PMID- 29455472 TI - Double-digest RAD sequencing outperforms microsatellite loci at assigning paternity and estimating relatedness: A proof of concept in a highly promiscuous bird. AB - Information on genetic relationships among individuals is essential to many studies of the behaviour and ecology of wild organisms. Parentage and relatedness assays based on large numbers of single nucleotide polymorphism (SNP) loci hold substantial advantages over the microsatellite markers traditionally used for these purposes. We present a double-digest restriction site-associated DNA sequencing (ddRAD-seq) analysis pipeline that, as such, simultaneously achieves the SNP discovery and genotyping steps and which is optimized to return a statistically powerful set of SNP markers (typically 150-600 after stringent filtering) from large numbers of individuals (up to 240 per run). We explore the trade-offs inherent in this approach through a set of experiments in a species with a complex social system, the variegated fairy-wren (Malurus lamberti) and further validate it in a phylogenetically broad set of other bird species. Through direct comparisons with a parallel data set from a robust panel of highly variable microsatellite markers, we show that this ddRAD-seq approach results in substantially improved power to discriminate among potential relatives and considerably more precise estimates of relatedness coefficients. The pipeline is designed to be universally applicable to all bird species (and with minor modifications to many other taxa), to be cost- and time-efficient, and to be replicable across independent runs such that genotype data from different study periods can be combined and analysed as field samples are accumulated. PMID- 29455473 TI - Comparison between magnetic resonance imaging, computed tomography, and arthrography to identify artificially induced cartilage defects of the equine carpal joints. AB - While articular cartilage changes are considered to be one of the initial events in the pathological cascade leading to osteoarthritis, these changes remain difficult to detect using conventional diagnostic imaging modalities such as plain radiography. The aim of this prospective, experimental, methods comparison study was to compare the sensitivity of magnetic resonance imaging (MRI), magnetic resonance arthrography, computed tomography (CT), and CT arthrography in the detection of artificially induced articular cartilage defects in the equine carpal joints. Defects were created in the antebrachiocarpal and middle carpal joint using curettage by a board-certified equine surgeon. Normal articular cartilage thickness varied from a maximum of 1.22 mm at the level of the distal aspect of the radius to a minimum of 0.17 mm in the proximal articular surface of the third carpal bone. Regarding cartilaginous defect measurements the remaining cartilaginous bed range from a maximum of 0.776 mm in the partial thickness defects, and 0 mm (defect reaches the subchondral bone) when total thickness defect were made. Computed tomography and magnetic resonance imaging were performed followed by CT arthrography and magnetic resonance arthrography after antebrachiocarpal and middle carpal intraarticular contrast administration. All images were reviewed by two board-certified veterinary radiologists, both of whom were blinded to the location, presence of, and thickness of the cartilage defects. A total number of 72 lesions in nine limbs were created. Mean sensitivity for localizing cartilage defects varied between imaging modalities with CT arthrography showing the best sensitivity (69.9%), followed by magnetic resonance arthrography (53.5%), MRI (33.3%), and CT (18.1%) respectively. The addition of contrast arthrography in both magnetic resonance and CT improved the rate of cartilage lesion detection although no statistical significance was found. Computed tomographic arthrography displayed the best sensitivity for detecting articular cartilage defects in the equine antebrachiocarpal and middle carpal joints, compared to magnetic resonance arthrography, MRI, and CT. PMID- 29455474 TI - Aging impacts CD103+ CD8+ T cell presence and induction by dendritic cells in the genital tract. AB - As women age, susceptibility to systemic and genital infections increases. Tissue resident memory T cells (TRMs) are CD103+ CD8+ long-lived lymphocytes that provide critical mucosal immune protection. Mucosal dendritic cells (DCs) are known to induce CD103 expression on CD8+ T cells. While CD103+ CD8+ T cells are found throughout the female reproductive tract (FRT), the extent to which aging impacts their presence and induction by DCs remains unknown. Using hysterectomy tissues, we found that endometrial CD103+ CD8+ T cells were increased in postmenopausal compared to premenopausal women. Endometrial DCs from postmenopausal women were significantly more effective at inducing CD103 expression on allogeneic naive CD8+ T cells than DCs from premenopausal women; CD103 upregulation was mediated through membrane-bound TGFbeta signaling. In contrast, cervical CD103+ T cells and DC numbers declined in postmenopausal women with age. Decreases in DCs correlated with decreased CD103+ T cells in endocervix, but not ectocervix. Our findings demonstrate a previously unrecognized compartmentalization of TRMs in the FRT of postmenopausal women, with loss of TRMs and DCs in the cervix with aging, and increased TRMs and DC induction capacity in the endometrium. These findings are relevant to understanding immune protection in the FRT and to the design of vaccines for women of all ages. PMID- 29455475 TI - Nutrition education in the care of patients with chronic kidney disease and end stage renal disease. AB - Diet counseling and nutrition education are recommended in the prevention and management of chronic kidney disease (CKD) and end-stage renal disease (ESRD). The importance of effectively addressing nutrition with patients has grown given the increasing prevalence of obesity, hypertension, and diabetes; conditions which influence CKD/ESRD. Dietary advice for individuals with CKD/ESRD can be seen as complex; and successful dietary management requires careful planning, periodic assessment of nutritional status, as well as monitoring of dietary compliance. In spite of recommendations and pressing need, formal training in nutrition and adequate preparation for providers is limited; and for physicians the lack of nutrition education has been acknowledged, repeatedly, as an area for improvement in medical training curricula. It has also been suggested that dietitians have an essential role in management of CKD in the primary care setting; however, dietitians who do not practice renal education daily may need training on the specific challenges in CKD/ESRD. The objectives of this chapter were to: characterize select nutrition education resources for providers who care for patients with CKD/ESRD; summarize key dietary components emphasized in the care of patients with CKD/ESRD; and address practical considerations in educational efforts focused on nutrition and CKD/ESRD. PMID- 29455476 TI - [Emphasis on the importance of chemical drug treatment for spinal tuberculosis]. PMID- 29455477 TI - [Application value of Xpert MTB/RIF in diagnosis of spinal tuberculosis and detection of rifampin resistance]. AB - OBJECTIVE: To investigate the application value of Xpert MTB/RIF in diagnosis of spinal tuberculosis and detection of rifampin resistance. METHODS: The 109 pus specimens were obtained from patients who were primaryly diagnosed as spinal tuberculosis. All of the pus specimens were detected by acid-fast stain, liquid fast culturing by BACTEC MGIT 960 and Xpert MTB/RIF assay to definite the differences in sensitivity and specificity of mycobacterium tuberculosis among detecting methods. Pus specimens obtained by different methods were deteceded by MTB/RIF test to analyze the self-influence on Xpert MTB/RIF test. The result of liquid fast culturing by BACTEC MGIT 960 was used as the gold standard; and the value of Xpert MTB/RIF assay in detecting rifampin resistance was analyzed. RESULTS: The sensitivity of acid-fast stain, liquid fast culturing by BACTEC MGIT 960 and Xpert MTB/RIF assay were 25.92%, 48.15%, 77.78%, respectively. The sensitivity of pus specimens obtained from open surgery, ultrasound positioning puncture and biopsy the sensitivity were 83.78%, 76.47%, 44.68% respectively deteceded by MTB/RIF test. According to the gold standard of the results of liquid fast culturing by BACTEC MGIT 960 assay, the sensitivity and specificity of Xpert MTB/RIF assay in detecting rifampin resistance were 80%(4/5) and 90.70%(39/43), respectively. CONCLUSIONS: Xpert MTB/RIF assay has higher value in diagnosis of spinal tuberculosi, and also can detect rifampin resistance. The number of mycobacterium tuberculosis in pus specimens has a great influence in the sensitivity of Xpert MTB/RIF assay. PMID- 29455478 TI - [Comparision of clinical effects between one-stage anterior and posterior approach in treating thoracolumbar tuberculosis with debridement and internal fixation]. AB - OBJECTIVE: To compare the outcomes of surgical operation by posterior or anterior approach only for thoracolumbar tuberculosis. METHODS: The clinical data of 97 patients with thoracolumbar tuberculosis underwent debridement and internal fixation from January 2005 to December 2014 were retrospectively analyzed. The study included 59 males and 38 females, with a mean age of 53.7 years ranged from 20 to 68 years. The course of disease was from 1 to 13 months with an average of (6.9+/-2.3) months. Among these patients, 43 cases were treated through one-stage anterior approach (anterior approach group) and 54 cases were treated through posterior approach (posterior approach group). The clinical data and imaging data of 97 cases were analyzed, including the operation time, intraoperative and postoperative blood loss, postoperative hospitalization time, complications, visual analogue scale(VAS), Oswestry Disability Index(ODI), Frankle grade, bone fusion time, and corrective rate of Cobb angle. RESULTS: Operation time, intraoperative and postoperative blood loss, postoperative hospitalization time, complication rate, and corrective rate of Cobb angle were(174.4+/-9.9) min, (885.0+/-95.7) ml, (103.2+/-11.5) ml, (15.1+/-0.7) d, 9.3%, (73.4+/-3.2)% in posterior group respectively, while in anterior approach group were(229.5+/-15.2) min, (1326.0+/-113.5) ml, (153.2+/-16.7) ml, (19.0+/-0.8) d, 16.3%, (62.3+/ 2.5)%, respectively, and there was significant difference between two groups. There was no significant difference in graft bone fusion between two groups. Postoperative VAS, ODI, Frankel grade of all patients were obviously improved, but there was no significant difference between two groups. CONCLUSIONS: Thoracolumbar tuberculosis could be cured by one-stage anterior or posterior approach with debridement, bone grafting and internal fixation, but posterior approach has advantages of less trauma and better deformity correction. PMID- 29455479 TI - [Clinical application of modified inverted L-shape incision by extraperitoneal approach to lumbosacral tuberculosis]. AB - OBJECTIVE: To explore the clinical effects of one-stage posterior transpedicular screw system internal fixation combined with anterior debridement and bone grafting with modified inverted L-shape incision by extraperitoneal approach in treating multiple lumbosacral tuberculosis. METHODS: The clinical data of 15 patients with multiple lumbosacral tuberculosis underwent operation from February 2008 to December 2014 were retrospectively analyzed. There were 9 males and 6 females with an average of (47.0+/-13.9) years old. The lesions involved L4-S1 in 12 cases, L4-S2 in 1 case, L3-S1 in 2 cases. Five cases complicated with nerve root symptoms and 2 cases with cauda equina symptoms. All patients were treated with posterior transpedicular screw system internal fixation combined with anterior L4,5, L5S1 debridement and bone grafting with modified inverted L-shape incision by extraperitoneal approach. Operation time, blood loss, incision length, first passage of gas by anus were recorded. The condition of bone fusion and focus absorption were observed by lumbar CT and MRI; and ESR and CRP were regularly rechecked. RESULTS: Fifteen patients were followed up for 18-24 months with an average of (20.0+/-2.73) months. All lumbosacral pain obtained improvement, and no hardware loosening, breaking, or bone graft block loosening was found. The operative time of anterior-posterior approach surgery was 210-250 min with an average of (231.0+/-12.1) min; the blood loss was 320-705 ml with an average of(495.0+/-130.3) ml; the incision length was 15-21 cm with an average of (16.4+/-3.4) cm, and the extended length of inverted L-shape incision was 6 to 9 cm with an average of (7.1+/-2.6) cm. The time of first passage of gas by anus was 14 to 40 h with an average of (24.1+/-7.4) h after operation. All bone graft obtained fusion at final follow-up, and spinal cord symptoms got recovery, ESR and CRP restored normal level with no recurred at 3 months after drug withdrawal. CONCLUSIONS: The treatment of multiple lumbosacral tuberculosis with posterior transpedicular screw system internal fixation combined with anterior debridement and bone fusion with modified inverted L-shape incision by extraperitoneal approach is feasible and practical. This method has advantages of little trauma, good exposure, less complications and high security. PMID- 29455480 TI - [Application of guide combined with probing the internal wall of pedicle screw trajectory for subaxial cervical pedicle screw placement]. AB - OBJECTIVE: To investigate the skill and evaluate the accuracy for application of guide combined with probing the internal wall of pedicle screw trajectory for subaxial cervical pedicle screw placement. METHODS: Subaxial cervical pedicle screw was inserted in 11 patients by the guide combined with probing the internal wall of pedicle screw trajectory from January 2014 to October 2016, including 7 males and 4 females with an average age of 48.1 years(ranged 32 to 63 years). There were 4 cases with cervical spondylotic myelopathy, 4 with fracture and dislocation of cervical vertebrae, 1 with cervical cord injury without fracture and dislocation, and 2 with atlantoaxialfracture and dislocation. The target pedicle's diameter, optimal entry point, sagittal angle and cross-sectional angle were measured by CT before operation. During operation, the pedicle screw inserted angle was controlled by a guide with a self-designed protractor and probed the internal wall of pedicle screw trajectory as medial safety margin of insertion screw. The accuracy of cervical pedicle screw was evaluated by CT with classification of four grades and assessed whether there was injury of spine cord or vertebral artery postoperatively. RESULTS: Seventy-one cervical pedicle screws were placed among 11 patients, and no one had been found with clinical manifestations of injury of spine cord (or nerve root) or vertebral artery after operation. According to postoperative CT scan for evaluating the grade of screw position, 52 screws were in grade 0, 13 in grade 1, 4 in grade 2, 2 in grade 3, and 91% (65/71) located in good position. In total, 6 screws were incorreted in placement, and 4 cases of them broke medial wall and 2 cases broke lateral wall. CONCLUSIONS: The method of probing the internal wall of pedicle screw trajectory for subaxial cervical pedicle screw placement is safe and reliable, but the studying curve is long. Probing the internal wall of pedicle screw trajectory and controlling the insertion angle by guide with a protractor are key points of this technology. PMID- 29455481 TI - [Mid-term follow-up and coping strategies of bone cement leakage after percutaneous kyphoplasty]. AB - OBJECTIVE: To retrospectively analyze the clinical data of 17 patients with bone cement leakage after percutaneous kyphoplasty and explore the leakage type and mid-term clinical effects. METHODS: The clinical data of 17 patients with osteoporotic vertebral compression fractures occurred bone cement leakage after percutaneous kyphoplasty from October 2011 to October 2016 were collected. There were 7 males and 10 females, aged from 68 to 87 years old with an average of 78 years. All the patients had the history of low emergy trauma who had normal activity and full self-care for living before trauma, and complained with the lower back pain without signs and symptoms of nerve root injury after trauma. According to the anatomical location by images, the bone cement leakage pathways was confirmed, the preoperative and postoperative vertebral body height and Cobb angle were measured, the improvement of spinal stenosis were recorded. Preoperative and postoperative visual analogue scale (VAS) and Oswestry Disability Index(ODI) were used to evaluate pain and daily activities. RESULTS: All the patients were followed up for 4 to 7 years with an average of 5.1 years. According to anatomical location by images, we found the bone cement leakage pathways of vertebral side type in 6 cases, intervertebral disc type in 3 cases, spinal canal type in 2 cases, vertebral pedicle type in 5 cases and mixed type in 1 case. Vertebral body height from preoperative(27.7+/-3.5)% restored to (56.4+/ 2.5)% at final follow-up, and the kyphosis was corrected with Cobb angle from preoperative(45.3+/-4.2) degrees corrected to(18.3+/-3.1) degrees at final follow-up. VAS score decreased from preoperative 7.9+/-1.5 to 2.1+/-0.5 at final follow-up. ODI obviously restored from preoperative(49.1+/-7.5)% to (23.5+/-3.7)% at final follow-up. The nerve symptoms in lower limbs occurred in 2 cases, and the neurological symptom was disappeared after urgent symptomatic treatment and anaphase trophic nerve treating. Lower back pain occurred in 3 cases, including one case of unbearable pain, and the pain disappeared after symptomatic treatment. CONCLUSIONS: Although the rate of bone cement leakage during percutaneous vertebral kyphoplasty is not low, the bone cement leakage has little influence on PKP surgery. Even if a little leakage occurred within the spinal canal during the surgery, spinal canal decompression will not be needed urgently. The significant clinical symptoms caused by leakage can basically disappear after treatment in mid-term follow-up. PMID- 29455482 TI - [Clinical efficacy of unilateral percutaneous transfacet screws combined with contralateral pedicle screw versus bilateral pedicle screws fixation in the treatment of the degenerative lumbar disease]. AB - OBJECTIVE: To investigate the surgical outcome of unilateral pedicle screw(UPS) after TLIF technique combined with contralateral percutaneous transfacet screw(PTS) fixation vs bilateral pedicle screws(BPS) fixation in treatment of degenerative lumbar disease. METHODS: From January 2009 to June 2012, 46 patients with degenerative lumbar diseases, including 30 males and 16 females with an average age of 51.5 years old, who were divided into two groups according to different fixation methods. Twenty-two cases underwent UPS after TLIF technique combined with contralateral PTS fixation (group A), while the others underwent BPS fixation(group B). The relative data were analyzed, such as blood loss volume, operative time, fusion rate, ODI score, JOA score and so on. RESULTS: All the patients were followed up for 1 to 3 years with an average of 22 months. Except one case of each group was uncertainty fusion, the rest have obtained bony fusion, and the fusion rates in group A and B were 95.5% and 95.8%, respectively. No displacement and breakage of screw were found during follow-up. Operative time and blood loss volume in group A were better than of group B(P<0.05). ODI and JOA scores had improved obviously than preoperation(P<0.05), but the differences had no statistical significance between two groups(P>0.05). CONCLUSIONS: Two approaches had similar clinical outcomes for degenerative lumbar disease with no severe instability. Compared with BPS fixation, the UPS after TLIF technique and contralateral PTS fixation has the advantages of less trauma, shorter operative time and less blood loss, and it is a safe and feasible surgical technique. PMID- 29455483 TI - [Analysis of clinical outcome of kyphoplasty on costal pain related to thoracic osteoporotic compression fractures]. AB - OBJECTIVE: To analyze the clinical outcome of kyphoplasty on costal pain which develops following thoracic osteoporotic compression fractures and evaluate the factors related to costal pain. METHODS: From May 2014 to May 2016, a total of 188 patients with thoracic osteoporotic compression fractures undergoing kyphoplasty were reviewed retrospectively. The patients were divided into two groups: the costal pain group included patients who had costal pain after a vertebral fracture and the no costal pain group included patients without costalgia. Visual analogue scale(VAS)and Oswestry Disability Index(ODI)of all patients were measured preoperatively and 3 days, 1 month, 6 months postoperatively respectively. Gender, age, the fracture level, bone mineral density, vertebral body fracture type, and fracture severity were compared between two groups, and the causes of costal pain were analyzed. RESULTS: Among 188 patients, 38 patients (20.2%) complained of costal pain with back pain. The mean follow-up time was 8.3 months (ranged from 6 to 15 months). The VAS and ODI score of two groups decreased after operation, and there was significant difference between pre-operation and post-operation(P<0.05). There was significant difference in VAS score and ODI score between two groups at 3 days and 1 month postoperatively (P<0.05). There was no significant difference in VAS score and ODI score between two groups at 6 months postoperatively (P<0.05). The incidence of applanation-type deformity and severe fracture in the costal group were higher. The fracture type and fracture severity showed significantly difference between two groups(P<0.05). CONCLUSIONS: The fracture type and fracture severity had significant relation to costal pain of thoracic osteoporotic compression fractures. The kyphoplasty effect on costal pain may not be effective, especially during early post-operation period.

METHODS: From April 2014 to January 2016, 36 cases of lumbar spondylolisthesis with adjacent segment degeneration were treated by MAST Quadrant(target nerve decompression and transforaminal lumbar interbody fusion or articulationes zygapophysiales fusion by unilateral fixation with MAST Quadrant). Twenty-three cases were degenerative lumbar spondylolisthesis and 13 cases were isthmic lumbar spondylolisthesis. According to Meyerding grade of spondylolisthesis, 16 cases were grade I, 17 cases were grade II, and 3 cases were grade III. Visual analogue score (VAS), Oswesty Disability Index (ODI) and JOA score were used to evaluate the clinical outcome. RESULTS: The amount of intraoperative bleeding was 230 to 480 ml with an average of 340 ml and the amount of postoperative blood loss was 15 to 80 ml with an average of 43 ml. Operative time was 176 to 240 min with an average of 193 min; X-ray exposure time was 2 to 6 s with an average of 3.6 s. Two cases were complicated with dural tear without nerve injury during operation. Thirty cases were followed up from 12 to 17 months with an average of 15.2 months. VAS scores for preoperative, 5 days, 3 months after surgery were 7.6+/-1.7, 1.9+/-0.4, 0.8+/ 0.4 respectively, and there was significant difference before and after operation(P<0.05). The ODI scores for preoperative and 3 months after surgery were 35.9+/-1.2 and 3.7+/-0.7 respectively, and there was significant difference before and after operation(P<0.05). JOA scores for preoperative, 5 days, 1 months, 3 months after surgery were 13.2+/-0.4, 24.4+/-0.4, 27.4+/-0.1, 27.9+/ 0.5 respectively, and there was significant difference before and after operation(P<0.05). CONCLUSIONS: MAST Quadrant can be applied to treat lumbar spondylolisthesis with adjacent segment degeneration, and the minimally invasive sugical technique is a safe and effective method, with the advantage of simple operation, fast recovery. PMID- 29455485 TI - [Risk factors of non-surgical vertebral fracture after percutaneous kyphoplasty of single segment thoracolumbar fracture]. AB - OBJECTIVE: To investigate the risk factors of non-surgical vertebral fracture after percutaneous kyphoplasty (PKP) in patients with single segment thoracolumbar osteoporotic vertebral compression fracture(OVCF). METHODS: The clinical data of 219 patients with single segment thoracolumbar osteoporotic vertebral compression fracture underwent percutaneous kyphoplasty from January 2010 to December 2015 were retrospectively analyzed. There were 29 cases in non surgical vertebral body fracture group with 7 males and 22 females aged (67.35+/ 9.92) years. Bone mineral density was(-3.89+/-0.72)SD, fracture compressed degree was (0.57+/-0.35)%, bone cement injected volume was (4.53+/-1.64) ml, and vertebral height recovery was (0.49+/-0.86)% on average. Ten cases were with vertebral body space fracture, 7 cases with bone cement leakage to the intervertebral disc, 9 cases with bone cement leakage to the peripheral tissue and 14 cases were treated by systemic anti-osteoporosis treatment after operation. Other 190 cases in non-surgical vertebral body without fracture group, and there were 42 males and 148 females, aged (66.98+/-7.55) years. Bone mineral density was (-3.13+/-0.59) SD, fracture compressed degree was (0.39+/-0.60)%, bone cement injected volume was (4.72+/-1.28) ml, and vertebral height recovery was (0.46+/-0.94)% on average. Among them, 13 cases were with vertebral body space fracture, 5 cases with bone cement leakage to the intervertebral disc, 29 cases with bone cement leakage to the peripheral tissue and 129 cases were treated by systemic anti-osteoporosis treatment after operation. The factors of gender, age, fracture compressed degree, fractured type, bone mineral density, bone cement injected volume, bone cement leakage, vertebral height recovery, adjacent vertebral fractures, and systemic anti-osteoporosis treatment were studied in the two groups for single factor analysis. For the results with significant differences among above factors, the multivariate logistic regression analysis was used to research the non-surgical vertebral fracture risk factors. RESULTS: Among the 219 patients with single thoracolumbar fractures, 29 cases occurred non-surgical vertebral fractures. The single factor analysis results showed that there was no significant correlation between non-surgical vertebral fracture occurrecne with age, sex, fracture compressed degree, bone cement injected volume, and vertebral height recovery(P>0.05), but there was a significant correlation between non-surgical vertebral fracture occurrence with fractured type, bone cement leakage, systemic anti-osteoporosis treatment, and bone mineral density (P<0.05). Multivariate logistic regression analysis showed that fractured type(OR=0.135), whether systemic anti-osteoporosis treatment (OR=3.793), bone cement leakage (OR=8.975), and bone density (OR=57.079) are risk factors for postoperative non-surgical vertebral fractures. CONCLUSIONS: Improving the quality of the people, systemic preventing and treating the osteoporosis, improving the surgical skills and decreasing the bone cement leakage during operation are effective methods to prevent postoperative non surgical vertebral fractures.

AB - OBJECTIVE: To evaluate the clinical results of anterior cervical discectomy and reconstruction with a self-locking cage and internal fixation with short segmental plate for multilevel cervical spondylotic myelopathy. METHODS: From January 2012 to June 2015, a total of 106 patients received anterior cervical discectomy and reconstruction with a self-locking cage and internal fixation with short segmental plate were followed up. There were 71 males and 35 females, aged from 42 to 74 years old with an average of(55.4+/-5.1) years. Three segments were involved in 82 cases and four segments in 24 cases. Operation time, blood loss, postoperative drainage, and hospitalization time were recorded. Visual analogue scale(VAS) and Japanese Orthopaedic Association Score (JOA) were analyzed before and after operation(including 5 days, 3, 6, 12 months after operation and final follow-up), and the JOA improvement rate was analyzed. The cervical lordosis and ROM were measured before and after operation(including the follow-up point above) by X-rays. The postoperative complications were recorded and analyzed as well. RESULTS: All the operations were successful. The average operative time was (126.2+/-25.1) min, and the amount of blood loss was (82.1+/-26.3) ml. All the patients were followed up from 12 to 48 months with an average of (30.4+/-10.5) months. The VAS score of neck pain and JOA score was significantly better from 6.11+/-1.54 and 9.22+/-2.42 preoperatively to 2.14+/-0.51 and 12.46+/-1.42 at 5 days post-operation, respectively(P<0.05). The improvement rate of JOA was (56.7+/-21.6)%, there was no statistically significant difference of VAS, JOA scores and the improvement rate of JOA at each time after operation (P>0.05). Postoperative cervical lordosis at 3 months was significantly improved from preoperative (11.5+/-6.8) degrees to (19.6+/-8.9) degrees (P<0.05), and it can keep satisfactory stability until final follow-up(P>0.05). Postoperative ROM at 3 months was significantly decreased from the preoperative (37.6+/-10.4) degrees to (18.2+/-5.9) degrees (P<0.05), but there was no significant change in the process of follow-up (P>0.05). All the complications such as dysphagia (19 cases), axial neck pain(6 cases), cerebral fluid leakage(3 cases), and hoarseness(2 cases), got better after conservative treatment. Three cases had intervertebral space non-fusion until final follow-up(without clinical symptom), but no loosening, breakage, or displacement of internal fixation were found. CONCLUSIONS: Anterior cervical discectomy, reconstruction with a self-locking cage and internal fixation with short segmental plate which can reduce intraoperative injury, restore cervical lordosis, improve neurological function and lower postoperative complications, it is an alternative treatment for multilevel cervical spondylotic myelopathy.

AB - OBJECTIVE: To evaluate the clinical effects of French door segmented laminectomy decompression for severe cervical OPLL complicated with spinal cord injury. METHODS: The clinical data of 38 patients with serious cervical OPLL complicated with spinal cord injury were retrospectively analyzed and these patients were treated with French door segmented laminectomy decompression and internal fixation from June 2012 to June 2014. There were 25 males and 13 females, aged from 42 to 78 years with an average of 58.2 years. Of them, 35 cases suffered from aggravating neurological symptoms with a definite precipitating factor. Spinal cord injury was related to minor injury of the neck, such as hyperextension of the neck in 3 cases. Preoperative Japanese Orthopaedic Score (JOA) was 8.1+/-1.7 and Neck Disability Index (NDI) was 19.8+/-4.4. Preoperative CT scans showed the range of OPLL was more than three segments. The spinal canal was occupied 50% to 85% with an average of 70.7%. RESULTS: All the patients were followed up for 10 to 24 months with an average of 15.6 months. The operative time was 90 to 150 min with an average of 120 min and blood loss was 300 to 800 ml with an average of (480+/-80) ml. At final follow-up, NDI and JOA were 7.5+/ 2.5 and 13.5+/-2.0, respectively, and they were obviously improved compared with preoperation. Preoperative cervical Cobb angle was (8.10+/-2.70) degrees and at final follow-up was (15.60+/-1.80) degrees , and there was significant difference between preoperative and postoperative (P<0.05). Deep infection occurred in 1 case, epidural hematoma in 1 case, C5 nerve root palsy in 3 cases, and axial symptom in 8 cases after operation. No serious complications, such as vertebral artery injury, cerebrospinal fluid leakage, deterioration of neurological dysfunction, or internal fixation failure was found. CONCLUSIONS: French door segmented laminectomy decompression is safe and feasible for severe cervical OPLL complicated with spinal cord injury, and it is worth to be popularized in future.

AB - OBJECTIVE: To compare the hemostatic effect between absorbable hemostatic fluid gelatin (HFG) and absorbable gelatin sponge(GS) during operation of unilateral open-door cervical expansive laminoplasty. METHODS: The clinical data of 83 patients underwent unilateral open-door cervical expansive laminoplasty from February 2014 to May 2016 were retrospectively analyzed. According to the used hemostatic materials, patients were divided into two groups. In HFG group, there were 30 males and 11 females, ranging in age from 29 to 81 years, with an average of(55.6+/-11.6)years; 14 cases were simple cervical spinal stenosis, 9 were cervical spinal stenosis and ossification of posterior longitudinal ligament, and 18 were cervical spinal stenosis complicated with multiple cervical disc herniation. And in GS group, there were 32 males and 10 females, ranging in age from 36 to 78 years, with an average of (55.4+/-11.1) years; 12 cases were simple cervical spinal stenosis, 10 were cervical spinal stenosis complicated with ossification of posterior longitudinal ligament, and 20 were cervical spinal stenosis complicated with multiple cervical disc herniation. There was no significant difference in the age, gender, and disease categories of patients between two groups (P>0.05). The operative time, intraoperative bleeding, postoperative drainage, and postoperative complications were compared between two groups. RESULTS: The average operative time, intraoperative bleeding, and postoperative drainage in HFG group were(137.2+/-30.0) min, (156.1+/-74.6) ml, and (212.1+/-67.6) ml, respectively; and in GS group were (154.8+/-33.5) min, (242.9+/-120.7) ml, and(303.3+/-115.5) ml, respectively. There were significantly differences in above items between two groups(P<0.05). No acute heamatoma or related complications was found postoperatively. CONCLUSIONS: Compared with GS, HFG can obviously decrease operative time, intraoperative bleeding, and postoperative drainage. It is a safe and effective hemostatic material for the operation of unilateral open-door cervical expansive laminoplasty. PMID- 29455489 TI - [Causes prevention and treatment for cerebrospinal leak after lumbar revision surgery]. AB - OBJECTIVE: To analyze the causes and explore the measures of prevention and treatment of the cerebrospinal leak after lumbar revision surgery. METHODS: The clinical data of 24 patients(17.78%) with cerebrospinal leak among 135 cases after lumbar revision surgery from January 2011 to January 2016 was retrospectively studied. Of them, 12 cases due to severe adhesion caused by scar formation; 4 cases due to yellow ligament hyperplasia adhesion with dura mater occurred dural tears when separating adhesion; 2 cases with severe hyperplasia and ossification of lumbar posterior longitudinal ligament occurred dural tears when revealing intervertebral disk; 2 cases due to improper nailing happened dural tears during operation. And the other 4 cases without obvious dural tears in surgery, occurred cerebrospinal leak one to two days after surgery. And the 24 patients were treated with the measures of prevention and treatment preoperatively, intraoperatively, and postoperatively. RESULTS: Twenty-four patients with cerebrospinal leak were cured after treatment and were follow-up for 6 to 30 months. No recurrence of cerebrospinal leake or local and systemic complications were found. CONCLUSIONS: Scar formation is the main cause of cerebrospinal leak in lumbar revision surgery. As for lumbar revision surgery, as long as the standard control measures are taken, it can significantly reduce the incidence of cerebrospinal leak, achieve better clinical efficacy, and fundamentally solve the cerebrospinal leak problem that has plagued both doctors and patients for a long time. PMID- 29455490 TI - [Clinical application of anterior thoracoscopically assisted surgery with posterior one-stage total en block spondylectomy for thoracic spinal tumor]. AB - OBJECTIVE: To investigate the clincial effects and feasibility of anterior thoracoscopically assisted surgery (TAS) with posterior one-stage total en block spondylectomy(TES) for thoracic spinal tumour. METHODS: From October 2014 to January 2016, 4 patients with thoracic spinal tumour were treated by anterior thoracoscopically assisted surgery with posterior one-stage total en block spondylectomy. There were 2 males and 2 females, aged 16, 35, 46, 60 years. Courses of disease were 1, 4, 6, 9 months. The tumor occurred at T4, T6, T130 segment in 1 case respectively, at double T7/T8 segments in 1 case. Preoperative visual analogue scores(VAS) were 4, 5, 6, 8 points. Frankel grade of neurologic function was grade B in 2, D in 1, and E in 1. SF-36 quality of life scores were 38, 65, 35, 29 points, including 2 cases of primary spinal tumors, 2 cases of metastatic spinal tumors. According to the classification of Tomita, 1 case was type III, 2 cases were type IV, 1 case was type VI. And according to the WBB staging, 4-9/ABCD was in 2 cases, 5-8/ABC compliated with 1-3 was in 1 case, 6 7/ABC was in 1 case. Surgical procedure: With lateral position, the thoracoscope channel was inserted. The involved intervertebral vessels and corresponding intercostal vessels were ligated, while the prevertebral large vessels were completely separated and protected. The front halves of superior and inferior involved vertebral discs were removed. Then the patients were changed to prone position, posterior one-stage total en block spondylectomy, titanium cage bone graft (allograft bone), pedicle screw fixation were performed. RESULTS: All of the operations were successful and the patients were followed up for 34, 10, 11, 12 months. Pleural effusion occurred in 1 case after operation, and pleural closed drainage was done. All incisions got primary healing; and all patients showed significant pain relief (P<0.005), with the VAS score decreasing to 2(2 cases) and 3(2 cases) scores, 2 months after surgery. No nerve functional injury aggravated. SF-36 quality of life score obviously improved with postoperative scores for 88, 92, 71, 80 at 3 months after operation. No recurrent vertebral tumor, internal fixation lossening or breakage was found at follow-up points of 3, 6, 12 months. One patient with lung cancer died of multiple organ failure at 11 months after operation. CONCLUSIONS: With anterior TAS, vertebral anterior vessels, intervertebral blood vessels, intercostal vessels were successfully separated or ligated, intraoperative bleeding was effectively controlled, lung and esophagus were effectively protected, and the tumor received wide excision. Anterior TAS and one-stage posterior TES could significantly reduce the surgical trauma and the risk of surgery.

PMID- 29455492 TI - [Relationship between inflammatory cytokines of IL-1beta and TNF-alpha and intervertebral disc degeneration]. AB - The inflammatory cytokines of IL-1beta and TNF-alpha participate in the process of intervertebral disc degeneration is focused by the spine surgeons. Inflammatory cytokines represented by IL-1beta and TNF-alpha act as the key factors in the process of intervertebral disc degeneration resulting in low back pain and radicular symptoms. Annulus fibrosus and nucleus pulposus can secrete TNF-alpha and IL-1beta under the stimulation of mechanical injury, overstressed, genetic susceptibility and infection. The mechanism of inflammatory cytokines in intervertebral disc degeneration needs further investigation. The emphasis of researches will be on the inflammatory cytokines in the regulation of mechanism in the intervertebral disc degeneration, molecular targeted therapy, cell signaling pathways and the best time of anti-inflammatory therapy providing more evidence in the clinical application. PMID- 29455493 TI - [Classification of upper cervical fractures: a review]. AB - Upper cervical fracture-dislocations are series of pathological injuries occurred in occipital, atlas and axis caused by traumatic impact, which often results in severe clinical consequences, such as paraplegia, quadriplegia, and even death. In light of the potential severe clinical outcomes, it is important to define the type of upper cervical fracture-dislocations depending on which the clinician can deal with the disease properly. Owing to its specific anatomical structures, the upper cervical fractures occurr to the unique osseous structures or ligamentous connections always present in predictable patterns. Common fracture include occipital condylar fracture, atlanto-occipital dislocation, atlas fracture, and the three types of fractures of axis, including odontoid fracture, Hangman's fracture and axis body fracture. In this paper we will review the literatures about the classification and management of upper cervical fracture, to help the clinicians to treat their patients better. PMID- 29455494 TI - [Progress on diagnosis and treatment of tophus]. AB - Tophi deposit in the peripheral bone joints or soft tissues are formed by uric acid and urate crystal. It does not only affect local appearance but also destroy the bone and joint structure, resulting in loss of function. Traditional medical treatment is an effective way to control the hyperuricemia, but it is ineffective to tophus. Surgery is a relatively effective method for the treatment of tophus. It can successfully reduces the content of uric acid in the body and improves the limbs function, but it causes surgical trauma and complications. As new medicine, Urcase is a hot spot in the present study. It can not only control the blood uric acid level but also dissolve part of tophus. But the cost is higher than traditional medicines. There is still dispute in treatment for advanced tophus. PMID- 29455495 TI - [Recent advances on the application and research of shoulder arthroscopy].

AB - OBJECTIVE: To retrospectively study curative effects of three repair methods for rotator cuff tears under arthroscopy, and to explore relationships between different repair methods and cuff lesions. METHODS: From January 2009 to Jaunary 2014, a total of 353 patients with rotator cuff tears treated with surgical repair under arthroscopy were included in this study. All the patients were divided into three groups according to time of visitiny hospital and it was divided into three periods. The patients on the first period were treated with single row rivet fixation(115 cases), including 51 males and 64 females, with an average age of (57.46+/-9.08) years old. The patients on the second period were treated with double row rivet fixation(163 cases), including 76 males and 87 females, with an average age of (56.93+/-9.92) years old. The patients in the third period were treated with suture bridge fixation(75 cases), including 32 males and 43 females, with an average age of (55.90+/-9.15) years old. There were 29 patients with huge rotator cuff injuries, who were treated with single-row suture. The shoulders were protected by a brace for 6 weeks after operations were permit ted to perform passive movement within 6 weeks, and then perform active shoulder exercise 6 to 10 weeks after operation. Constant-Murley score, UCLA score and VAS score were recorded preoperatively and postoperatively. RESULTS: All the patients were followed up, and the duration ranged from 12 to 62 months, with a mean of 30 months. There was no infection or nerve injury. UCLA score was improved from preoperative 10.71+/-2.45 to postoperative 32.07+/-3.16; Constant Murley score was improved from preoperative 43.33+/-11.55 to postoperative 78.15+/-12.64; VAS score was improved from preoperative 5.81+/-1.27 to postoperative 0.52+/-0.71. There were no statistical differences among three groups in UCLA score, Constant-Murley score and VAS score. Total 337 cases were satisfied with treatment results and 16 cases were not satisfied with the results. Among the 16 cases, 3 cases had huge rotator cuff surgery, and 13 cases had no joint stiffness before operation. The main complaints that resulted in dissatisfaction were weakness of the postoperative muscles and failure to restore the labour capacity(11 cases). CONCLUSIONS: Rotator cuff repair under arthroscopy has a reliable clinical effect for the patients with rotator cuff tears. Stable and reliable clinical results can be obtained regardless different repair methods or different rotator cuff tears. The following factors such as no stiffness before operation, too early active exercise and preoperative rotator cuff atrophy may be the risk factors for postoperative dissatisfaction of patients. PMID- 29455497 TI - [Clinical research of treating the avulsed fracture of humerus greater tuberosity using an arthroscopic double-row suture anchor fixation technique]. AB - OBJECTIVE: To evaluate the early clinical effects of treating the avulsed fracture of humerus greater tuberosity using the double-row suture anchor fixation technique. METHODS: Total 20 patients with the avulsed fracture of the greater tuberosity of the humerus were treated from September 2009 to January 2013. There were 12 males and 7 females, with an average age of 46.8 years old(24 to 69 years old). Eleven patients had injuries on right shoulder joint and 8 patients had injuries on left side. The injury mechanism included 10 cases of traffic accident, 6 cases of sports injury, and 3 cases of falls. The mean interval from injury to surgery was 34.9 d (ranged, 3 to 72 d). The affacted arm was suspended and fixed within 3 weeks after operation. The swing exercise of shoulder joint was performed from the 2nd day after operation. The strap was removed 3 weeks after operation, and painless active exercise was performed 6 weeks after operation. The patients were followed up in the outpatient department 6, 12 and 24 weeks after operation, and then every 6 months. AP and lateral X-ray films were taken at each follow-up time. At the latest follow-up, protractor was used to measure activity of patients; and VAS pain score, California University of Losangeles(UCLA) standard, American Shoulder and Elbow Surgeons (ASES) score were used to evaluate therapeutic effects. RESULTS: All the patients were followed up, with a mean duration of 35.2 months (ranged, 24 to 48 months). All the incisions were healed on the first stage without secondary acromion impingement and other complications. All the patients had bony union within 12 weeks. The movements of shoulder joints including flexion, abduction, external rotation, internal rotation were increased obviously(P<0.05). The UCLA score was increased from preoperative 15.2+/-5.3 to 35.6+/-6.1 at the latest follow-up. The ASES score was increased from preoperative 31.2+/-5.4 to 91.2+/-6.8 at the latest follow-up (P<0.05). CONCLUSIONS: It has satisfactory curative effects for the avulsed fracture of humerus greater tuberosity using the double-row suture anchor fixation technique, especially the cases of small or comminuted fractures. It has several advantages such as firm fixation, simple and secure operation as well as quick postoperative recovery. Finally, patient should take exercises actively after operations. PMID- 29455498 TI - [Radiologic observation of the blood supply changes around the knee with osteoarthritis]. AB - OBJECTIVE: To compare blood supply changes around the knee joint between normal and osteoarthritis knee. METHODS: From June 2014 to June 2015, 30 patients with knee osteoarthritis and 30 healthy adults were recruited. In osteoarthritis group, there were 9 males and 21 females, with a mean age of (65.967+/-7.132) years old(ranged, 53 to 82 years old), and the mean arterial pressure was(93.462+/-7.633) mmHg. In control group, there were 9 males and 21 females, with a mean age of (62.867+/-6.356) years old(ranged, 50 to 75 years old), and the mean arterial pressure was (92.122+/-9.675) mmHg. Inspection methods included color ultrasonic and computed tomography angiography of lower limbs. The patients were observed with: (1)collateral circulation; (2)artery circuity; (3)artery malformation; (4)artery stenosis; (5)arterial wall plaque formation. Stenosis was divided into 5 levels: level 1 as no narrow, level 2 as mild stenosis (1% to 49%), level 3 as moderate stenosis (50% to 70%), level 4 as severe stenosis (70% to 99%), level 5 as total obstruction. Diameter and blood flow dynamics of popliteal artery, pretibial artery, and posterior tibia artery in two groups were measured and compared. RESULTS: The study was accomplished with complete data collection, none of the patients was eliminated, and there were no loss of follow up. There were 3 cases in OA group and 4 cases in control group with the formation of collateral circulation, and the difference had no statistically significance. There was none in OA group and 2 in control group with the formation of artery circuity, and the difference had no statistically significance. There were no cases in both groups with artery malformation. In OA group, there was mild in 14 cases, moderate in 7 cases, severe in 9 cases. In control group, there was no arterial stenosis in 9 cases, mild in 10 cases, moderate in 6 cases, severe in 4 cases, total obstruction in 1 case. The difference between two groups was statistically significant; artery stenosis in OA group was more severe than that of the control group. Artery plaque formed in 30 cases in OA group and in 20 cases in control group. The difference between two groups was statistically significant; the rate of artery plaque formation in OA group was obviously higher than that of control group. In OA group, plaque calcification rate was 100% while 63% in control group. Difference of pretibial artery diameter was statistically significant, pretibial artery diameter is larger in OA group. Difference of popliteal artery flow velocity was statistically significant; velocity was faster in OA group. Difference of the posterior tibial artery flow velocity was statistically significant; velocity was faster in OA group. The differences of the three arteries had no statistical significances in related to arterial flow. CONCLUSIONS: Local artery system changes with the onset of knee joint osteoarthritis. Main pathological changesof local blood vessels were stenosis and plaque formation, but the amount of local artery blood flow was roughly the same as the control group. Possible mechanism is that the local artery stenosis speed up the artery blood flow velocity, resulting local perfusion. The local tissue ischemia and hypoxia caused a series of pathological changes. It is better to improve local vascular lesions than to accelerate the blood flow velocity in clinical treatment. Further more, interventional therapy for vascular pathology will be a new trend of osteoarthritis treatment.

METHODS: Total 26 adult patients with cubitus varus deformity were treated by operation from March 2011 to June 2015, 15 patients were boys and the other 11 patients were girls, ranging in age from 4 to 13 years, with an average of 7.8 years. The cubitus varus angel ranged from 11 degrees to 24 degrees, with a mean(17.50+/ 6.73) degrees, 3 patients complicated more than 10 degrees constriction of flexion. Lateral closing wedge osteotomy retaining the medial 3 to 4 mm intact cortex by lateral elbow approach was applied in these 26 patients. The wedge defect were closed and fixed by crossing pinning. The lateral column compression was achieved with external tension band(the crossing pins were bended laterally and the pin ends were hooked mutually). The pre-operative, post-oparetive and contralateral carrying angles were compared and Laupattarakasem criteria was used to evaluate the results at follow-up. RESULTS: All the patients got bony union 2 months after operation and there was no infection or nerve palsy. The average follow-up period was 18.8 months (ranged, 13 to 29 months). The carrying angle was restored to(11.50+/-3.17) degrees(ranged, 8 to 14 degrees). According to the Laupattarakasem evaluation criteria, 14 patients got an excellent result, 13 good and 1 fair. CONCLUSIONS: Normal carrying angle and elbow flexion could be restored by lateral closing wedge osteotomy, and stable fixation could be achieved with crossing pinning and external tension band, which is available for early mobilization.

AB - OBJECTIVE: To investigate the clinical effects of arthroscopic repair and arthroscopic-assisted small incision repair for the treatment of rotator cuff injury. METHODS: The clinical data of 86 patients with rotator cuff injury from January 2012 to January 2015 were analyzed retrospectively. All the patients were divided into two groups: arthroscopic assisted small incision repair group(group A) and arthroscopic repair group(group B). There were 46 patients in group A, including 25 males and 21 females, with an average age of (52.8+/-7.8) years old. And there were 40 patients in group B, including 23 males and 17 females, with an average age of (53.2+/-9.5) years old. Several indexes such as shoulder joint activity, muscle strength and ASES, UCLA and VAS scores were examined before and after operation to compare therapeutic effects between these two groups. RESULTS: All the patients were followed up, and the mean time was 20.8 months (ranged, 18 to 35 months). The results of patients in group A as follows: range of abduction motion of shoulder joint was (131.4+/-18.8) degrees , external rotation was (64.9+/-8.8) degrees , and internal rotation was(63.7+/-7.3) degrees . Results of patients in group B as follows: range of abduction motion of shoulder joint was(132.3+/-16.9), external rotation was(65.1+/-9.4) degrees , and internal rotation was(64.4+/-8.1) degrees . All the patients had better shoulder mobility than those before operation, but there were no significant differences between two groups after operation. Postoperative scores of patients in group A: ASES was 88.4+/-8.9, UCLA score was 29.6+/-3.6, VAS was 1.4+/-0.3; and in group B, the above scores were 89.5+/-9.6, 30.8+/-4.1 and 1.3+/-0.4 respectively. All the patients had better scores than those before operation, but there were no significant differences between two groups after operation. CONCLUSIONS: Arthroscopic repair and arthroscopic-assisted small incision for repair of rotator cuff injury has clinical curative effects to some extent, and these two methods could improve the safety and reliability of surgical treatment.

AB - OBJECTIVE: To observe the effect of core strength training on knee joint function and postural stability after anterior cruciate ligament reconstruction (ACLR). METHODS: A total of 80 ACLR patients were randomly allocated into conventional rehabilitation training group and core strength training group from May 2013 to May 2015 with 40 patients in each group. The patients in conventional rehabilitation training group underwent conventional ACLR rehabilitation training, in which 28 males and 12 females. The mean age was(30.5+/-5.2) years old(ranged, 22 to 42 years old). The mean BMI was(23.8+/-2.4) kg/m2(ranged, 18.2 to 25.9 kg/m2). Thirty patients had injuries on the dominant side and 10 patients had injuries on the non-dominant side. The core strength training group received conventional ACLR rehabilitation training and core strength training, in which 31 males and 9 females. The mean age was(31.1+/-4.8) years old(ranged, 21 to 45 years old). The mean BMI was(24.1+/-2.7) kg/m2(ranged, 18.5 to 26.1 kg/m2) . Twenty-seven patients had injuries on the dominant side and 13 patients had injuries on the non-dominant side. The Lysholm score, tibial anterior transition measured by KT-1000 before and after treatment, and the Star Excursion Balance Test results after treatment were compared between the two groups. RESULTS: Six months after rehabilitation training, the tibial anterior transition of the conventional rehabilitation training group and the core strength training group were(3.4+/-1.0) mm and(3.3+/-1.2) mm respectively, which were less than(12.1+/ 1.8) mm and(12.5+/-2.0) mm before treatment. But there was no significant difference in anterior tibial translation between two groups(P>0.05). The Lysholm score of the conventional rehabilitation training group and the core strength training group were 91.8+/-4.3 and 92.1+/-3.9 individually, which were higher than 69.2+/-5.8 and 70.2+/-5.1 before treatment. But there was no significant difference in Lysholm score between two groups(P>0.05). Six months after rehabilitation training, the results of Star Excursion Balance Test showed the reach distance with the support in the injured side and healthy side in the core strength training group were greater than that of the conventional rehabilitation training group in the eight directions(P<0.05). CONCLUSIONS: The core strength training could improve the dynamic balance of ACLR patients.

AB - OBJECTIVE: To observe the effect of the meniscus shaping on the knee function and stability after anterior cruciate ligament reconstruction(ACLR). METHODS: A total of 64 ACLR patients were included from January 2013 to January 2015. The control group was the ACLR patients with intact meniscus, in which 24 males and 6 females. The mean age was(32.8+/-5.5) years old(ranged, 22 to 43 years old). The injury side was left on 17 cases and right on 13 cases. The mean follow-up time was(15.2+/-2.8) months(ranged, 12 to 19 months). The shaping group was the ACLR patients with meniscus shaping, in which 27 males and 7 females. The mean age was (33.1+/-4.2) years old (ranged, 23 to 42 years old). The injury side was on the left in 22 case and right in 12 cases. The mean follow-up time was (16.0+/-3.1) months (ranged, 12 to 20 months). The preoperative anterior tibia shift and knee joint function, as well as anterior tibia shift, knee joint function and active proprioception at last follow-up time were observed. The anterior tibia shift was measured by KT-1000. The knee joint function was assessed by Lysholm score and KOOS score. The errors of active proprioception were measured at 30 degrees , 45 degrees and 60 degrees knee flexion. RESULTS: Postoperative anterior tibia shift of the affected side was (1.4+/-0.2) mm, which was lower than (2.2+/-0.4) mm in shaping group(P<0.05). The postoperative total Lysholm scores of the control group and the shaping group were 93.7+/-2.7 and 92.3+/-3.0 respectively, which were higher than 52.8+/-3.9 and 51.6+/-5.1 preoperatively(P<0.05), but there were no significant differences between two groups(P>0.05). In the KOOS score, the postoperative symptoms, pain, daily life, exercise capacity and life quality in control group were 90.7+/-5.5, 93.2+/-4.3, 96.8+/-2.2, 90.9+/-5.3, 91.8+/-4.5 respectively, which were higher than 72.7+/-6.0, 70.6+/-7.3, 72.5+/ 7.4, 52.8+/-5.4, 36.2+/-6.5 preoperatively(P<0.05); the postoperative symptoms, pain, daily life, exercise capacity and life quality in the shaping group were 88.9+/-5.8, 92.6+/-3.5, 96.5+/-2.1, 89.3+/-7.2, 90.6+/-4.1 respectively, which were higher than 71.9+/-5.1, 71.2+/-7.1, 71.3+/-6.2, 53.1+/-6.1, 35.6+/-4.7 preoperatively(P<0.05). No significant differences were observed in each postoperative item of KOOS between the two groups(P>0.05). No significant differences were observed in the postoperative active proprioception error of contralateral side between the control group(12.2+/-3.4) degrees and shaping group(12.8+/-3.2) degrees (P>0.05). The error of active proprioception in the affacted side of the control group was(13.5+/-3.7) degrees , which was lower than that in the shaping group(17.1+/-4.2) degrees (P<0.05). In control group, there was no significant difference in the active proprioception error between two sides(P>0.05). While in shaping group, the error of active proprioception in the affacted side was significantly greater than that in the contralateral side(P<0.05). CONCLUSIONS: In short and medium term, meniscus shaping has no effect on knee joint function in patients with ACLR, but it impairs the knee proprioception and stability. PMID- 29455503 TI - [Diagnostic value of Blumensaat angle for anterior cruciate ligament injury]. AB - OBJECTIVE: The receiver operator characteristic(ROC) curve was used to determine the best Blumensaat angle for the diagnosis of anterior cruciate ligament injury, so as to objectively evaluate the diagnostic value of Blumensaat angle for anterior cruciate ligament injury. METHODS: Total 167 patients who had knee arthroscopic treatment in a hospital from January 2015 to January 2016 were retrospectively studied, and the patients' age, gender, left and right limb condition were recorded. The patients were divided into two groups according to Blumensaat angle measured on the MRI: group A(Blumensaat angle<=0 degrees ), and group B(Blumensaat angle >0 degrees ). The ROC curve was drawn from the statistical data of the group B to get the best critical value of the anterior cruciate ligament injury when the Blumensaat angle was more than 0 degrees . According to the best critical value obtained by ROC curve, the coincidence rate of the total sample was obtained. RESULTS: There were no significant differences in patients' age, gender, and affected limbs. There were 51 patients in group A, in which 49 patients were diagnosed as anterior cruciate injury under arthroscopy(gold standard for diagnosis of anterior cruciate ligament injury), and 2 patients were diagnosed as no anterior cruciate injury under arthroscopy. When the Blumensaat angle was<0 degrees , the coincidence rate was 96.07%. In group B(116 cases), the area under the ROC curve was 0.910, the best cutoff corresponds to 15 degrees ; the sensitivity was 70.0%, and the specificity was 95.8%. When the Blumensaat angle was >=15 degrees , the probability of anterior cruciate ligament injury was greater. When the Blumensaat angle was 0 degrees to 15 degrees , the anterior cruciate ligament was more likely to be not injured. The Blumensaat angle<=0 degrees or>=15 degrees were used to diagnose the injury of anterior cruciate ligament. Compared with the results of arthroscopy, the coincidence rate of the total sample was 92.8%. CONCLUSIONS: Blumensaat angle is helpful to diagnose the ACL injuries. When the Blumensaat angle was <=0 degrees or >=15 degrees , the probability of ACL injury is greater.

AB - OBJECTIVE: To evaluate the clinical efficacy of open supracondylar osteotomy of the femoral condyle for the treatment of valgus knee osteoarthritis. METHODS: From April 2008 to June 2015, 21 patients with valgus knee osteoarthritis underwent an open wedge femoral supracondylar osteotomy using the distal femur dissection plates combined with autologous iliac bone graft for the bone defect. There were 8 males (8 knees) and 13 females (15 knees), ranging in age from 30 to 54 years old, with a mean age of 41.2 years old. All the patients had valgus deformity and knee joint pain in the lateral compartment. The average tibiofemoral angle was (162.0+/-2.6) degrees which was measured on the image of preoperative lower extremity weight-bearing X-ray. Clinical outcomes were comprehensively assessed according to the bone healing time, postoperative complications, progress of knee osteoarthritis after operation, the Hospital for Special Surgery rating system (HSS), and tibiofemoral angle before and after operation. RESULTS: All 21 patients were followed up, the valgus deformity of knee joint was corrected in all patients after operation. No obvious delayed union or nonunion were found, and no serious complications were found. The HSS knee score was improved from the preoperative 57.3+/-3.1 to the final follow-up time 88.6+/-2.7. Tibiofemoral angle was improved to the postoperative(176.0+/ 1.4) degrees . CONCLUSIONS: Open wedge femoral supracondylar osteotomy has a clear surgical approach, and it is easy to control the bone mass of osteotomy and can effectively correct the valgus deformity and improve the function of knee joint using this method. It is an effective method for the treatment of valgus knee osteoarthritis in young and middle-aged patients. PMID- 29455504 TI - [Clinical effects of rehabilitation exercise in the treatment of knee osteoarthritis based on the theory of "treating muscle for bone"]. AB - OBJECTIVE: To study the efficacy and safety of voluntary rehabilitation exercise in the treatment of knee osteoarthritis, based on the traditional Chinese medicine theory of "treating muscle for bone". METHODS: Ninety participants with early knee osteoarthritis were randomly divided into experimental group (n=45) and control group (n=45). Patients in experimental group were treated with voluntary rehabilitation exercise combined with isometric extension of quadriceps femoris. Patients in control group were treated with apparatus training combined with isometric extension of quadriceps femoris. The treatment course lasted for two weeks. Visual analogue scale (VAS), Lysholm score and total therapeutic effect were evaluated before and after treatments. RESULTS: After two weeks of treatment, cure-remarkable-effective rate in experimental group (86.67%) was higher than that in control group (71.11%). The VAS scores and Lysholm scores were significantly improved in both two groups (P<0.05). The results were significantly better in experimental group those in control group (P<0.05). There were no serious adverse events. CONCLUSIONS: Voluntary rehabilitation exercise combined with isometric extension of quadriceps femoris was effective and safe in the treatment of early knee osteoarthritis.

AB - OBJECTIVE: To study the effect of greater trochanteric slide osteotomy(GTSO) in total hip arthroplasty (THA) for the treatment of stiff hip, as well as the potential complications. METHODS: There were 12 cases enrolled in the study from April 2010 to December 2014, including 9 males and 3 females. The mean age was 49.9 years old (ranged, 37 to 62 years old). The clinical result was evaluated according to the Harris evaluation system, and the radiological evaluations included the healing of the osteotomy, the stability of the prosthesis, and occurrence of heterotopic ossification (HA). RESULTS: The mean follow-up period was 17.3 months (ranged, 15 to 22 months). The mean postoperative Harris score was 88.00+/-6.11, which was significantly higher than the preoperative mean score which was 43.96+/-8.46(t=-18.34, P=0.00). All the osteotomy site abtained good healing without prosthesis loosening or HA. There was 1 patient with infection and 1 patient with pain in greater trochanter. CONCLUSIONS: GTSO is an effective exposure technique in THA for stiff hip, and no marked complication associated with the osteotomy is found in the study.

AB - OBJECTIVE: To explore the effects and related mechanisms of total flavone of epimedium treatment(TFE)on primary callus for mation in ovariectomized rats. METHODS: Forty male SD rats weighted from 209 to 246 g and aged 6 to 8 weeks were selected. Six weeks after ovariectomy a femur fracture model with middiaphyseal segment fracture was established, estimated and randomly divided into TFE group (150 mg.kg-1.d-1) and control group(received saline). HE staining was used to evaluate the morphologic difference of primary callus during the bone callus healing between these two groups. The relative expression of Runt-related transcription factor 2(Runx2) mRNA in the callus was identified by real-time polymerase chain reaction. Immunohistochemical technique was used to observe the Casein kinase 2-interacting protein 1(CKIP-1) protein level in the callus of the two groups. Maximum fracture load was tested by three point bend test. RESULTS: The BMD, primary callus volume, trabecular member(Tb.N) and trabecular thickness(Tb.Th) were higher in TFE group than that in control group(P<0.001). The Tb.N and Tb.Th of primary callus were higher in TFE group than control group (P=0.001). The volume and bone volume/tissue volume of primary callus were in TFE group than control group(P<0.01). The trabecular separation(Tb.Sp) of primary callus were in control group higher than TFE group(P<0.01). The HE staining of the 6 week slices showed that the degree of cartilage ossification in callus of the TFE group was significantly higher than that in control group under high magnification. Real-time PCR revealed that the comparative expression of Runx2 mRNA in control group was higher than that in TFE group(P<0.001); the positive number of CKIP-1 was less in TFE group than that in control group (P<0.001). TFE could increase the maximum load of the primary callus (P<0.001). CONCLUSIONS: TFE can promote the cartiage ossification of callus in ovariectomized rats, enhancing the bone strength and bone quality in the process of fracture healing via the CKIP-1/Runx2 pathway.

AB - OBJECTIVE: To evaluate the clinical effects of arthroscopic microfracture on osteochondral lesions of the talus. METHODS: Total 42 patients with osteochondral lesions of the talus, who were collected in our department from January 2011 to December 2013. The patients were 35.9 years old on average, including 28 males and 14 females. There were 34 patients who had injury histories. The debridement and microfracture were performed under arthroscopy. The function of ankle was assessed according to AOFAS Ankle Hindfoot Scale. MRI of ankle was checked 2 years postoperatively. RESULTS: There were 23 cases in stage 3, 9 cases in stage 4 and 10 cases in stage 5 in MRI. There were 25 cases on the 4th district, 11 cases on the 6th district, 4 cases on the 1st district, 2 cases on the 3rd district according to 9 districts location and 8 cases of subchondral cyst found on the 4th district. AOFAS Ankle Hindfoot Scale of all patients on the 1st year postoperatively was 73.3+/-3.9 which was significantly better than 50.4+/-7.8 preoperatively, and 81.1+/-4.8 on the 2nd year postoperatively was also significantly better than that on the 1st year postoperatively. CONCLUSIONS: Arthroscopic microfracture for the osteochondral lesions of the talus could have a good clinical effect. PMID- 29455509 TI - [Treatment of Sanders II calcaneus fractures via minimally invasive sinus tarsi approach]. AB - OBJECTIVE: To study the feasibility and clinical efficacy of a minimally invasive sinus tarsi approach in the treatment of Sanders II calcaneus fractures. METHODS: From August of 2015 to July of 2016, 13 patients(totally 13 feet) with Sanders II intra-articular calcaneus fractures were treated via the minimally invasive sinus tarsi approach. The Bohler angle, Gissane angle and the length, width and height of calcaneus were compared between pre-operation and post-operation. The AOFAS ankle and foot scoring system of the orthopaedic ankle foot Association was used to evaluate the efficacy. RESULTS: All the patients were followed up, and the duration ranged from 6 to 15 months, with an average of 9.5 months. No incision complications occurred. The Bohler angle was increased from preoperative (18.82+/ 5.11) degrees to postoperative(26.63+/-4.45) degrees (t=-4.16, P=0.000). The Gissane angle was increased from preoperative(111.07+/-15.36) degrees to postoperative (124.56+/-8.71) degrees (t=-2.75, P=0.011). The length, width, height of calcaneus were absolutely improved from preoperative(69.82+/-5.95) mm, (42.07+/-3.68) mm, (41.20+/-3.90) mm to preoperatively(72.61+/-5.46) mm, (39.10+/ 4.02) mm, (44.03+/-3.33) mm. According to the AOFAS, 8 patients got an excellent result, 4 good and 1 poor, and the postoperative mean score was 88.2+/-5.9. CONCLUSIONS: The limited open sinus tarsi approach could be used successfully to treat displaced Sanders II fractures with less injury and effectively restored the surface of subtalar joint, however the method is not fit for the patients with comminuted fracture in lateral wall and great change in the length, width, height, varus and valgus of calcaneus. PMID- 29455510 TI - [Application of high fibular osteotomy in the treatment of knee osteoarthritis]. AB - OBJECTIVE: To evaluate the short-and mid-term curative effect of high fibular osteotomy on knee osteoarthritis. METHODS: From October 2014 to July 2016, 76 patients with knee osteoarthritis were treated with high fibular osteotomy. There were 22 males and 54 females, ranging in age from 47 to 82 years old, with an average of 61.62 years old. Internal tenderness of the knee joint was examined preoperatively. Preoperative examination showed medial knee pain and medial positive McMurray sign. Preoperative AP and lateral X-ray films of the weight bearing side of the knee showed the narrowing of the medial space. The knee medial space, femoral and tibial angle, VAS pain score and the American Knee Society(AKS) score were evaluated after operation. RESULTS: Compared with the preoperative one, the postoperative knee medial gap was widened obviously. The femur and tibia angle after operation was bigger than that before surgery. The VAS was improved from preoperative 5.70+/-1.56, to 3.70+/-1.03 at the 1st week after operation, 3.20+/-0.95 at the 1st month after operation, 2.35+/-0.99 at the 3rd month after operation, and 2.10+/-0.97 at the 1st year after operation. According to the AKS score, the preoperative pain score of knee joint was 14.45+/ 1.76, the activity score of knee joint was 12.60+/-1.98, and the stability score was 12.15+/-1.72; after operation, the above scores were improved to 42.60+/ 2.28, 21.80+/-2.14, and 20.85+/-2.16 respectively. CONCLUSIONS: The high fibular osteotomy with less complications is simple. It can effectively alleviate the pain of the knee joint and improve the function of knee joint, and the clinical effect is satisfactory.

AB - Although the function of the anterolateral stabilizing structures of the knee in the anterior cruciate ligament (ACL) injuries has been recognized since many years, most of orthopedic surgeons do not take the anterolateral structure into consideration when performing an ACL reconstruction. Anatomic ACL reconstruction will improve knee stability, but a small subset of patients may experience some residual anteroposterior and rotational instability. For this reason, some researchers have paid attention to the anterolateral aspects of the knee, especially the anterolateral ligament. We don't know the best time to perform ACL and ALL reconstruction. And we lack the evidence to prove which technique is the best one. So we look forward to more random controlled trial. PMID- 29455515 TI - [Research on promotory effect of traditional Chinese medicine on fracture healing in cell and molecular level]. AB - Traditional Chinese medicine is widely used in the treatment of fractures, osteoporosis, other bone related diseases for thousands of years. There are many animal experiments and clinical trials demonstrating that the traditional Chinese medicine such as epimedium, Drynaria and other traditional Chinese medicine can stimulate bone regeneration and inhibit bone resorption, accelerating the fracture healing. In recent years many cell experiments have shown that these herbal ingredients up-regulated the expression of intracellular osteogenic transcription factors and osteogenic related genes, and then induced osteoblastic differentiation and stimulated the proliferation of osteoblasts, bone nodule formation and matrix mineralization. Meanwhile these herbal ingredients up regulated the expression of intracellular osteoclastic transcription factors and osteoclast related genes, inhibited osteoclast differentiation and bone resorption of osteoclasts. In addition, intracellular signaling pathways regulated these herbal ingredients by might be involved in the above effects. We can have a conclusion that the genes expression regulated by transcription factors in pre-osteoblast and pre-osteoclast and these signaling pathways are the major molecular mechanisms and research hotspots of traditional Chinese medicine in promoting fracture healing. Based on these molecular mechanisms to review, this review provides not only the foundation for the study of traditional Chinese medicine in promoting fracture healing, but also the basis for clinical treatment of fracture. PMID- 29455516 TI - Core-Shell Microneedle Gel for Self-Regulated Insulin Delivery. AB - A bioinspired glucose-responsive insulin delivery system for self-regulation of blood glucose levels is desirable for improving health and quality of life outcomes for patients with type 1 and advanced type 2 diabetes. Here we describe a painless core-shell microneedle array patch consisting of degradable cross linked gel for smart insulin delivery with rapid responsiveness and excellent biocompatibility. This gel-based device can partially dissociate and subsequently release insulin when triggered by hydrogen peroxide (H2O2) generated during the oxidation of glucose by a glucose-specific enzyme covalently attached inside the gel. Importantly, the H2O2-responsive microneedles are coated with a thin-layer embedding H2O2-scavenging enzyme, thus mimicking the complementary function of enzymes in peroxisomes to protect normal tissues from injury caused by oxidative stress. Utilizing a chemically induced type 1 diabetic mouse model, we demonstrated that this smart insulin patch with a bioresponsive core and protective shell could effectively regulate the blood glucose levels within a normal range with improved biocompatibility. PMID- 29455517 TI - Highly Sensitive Bulk Silicon Chemical Sensors with Sub-5 nm Thin Charge Inversion Layers. AB - There is an increasing demand for mass-producible, low-power gas sensors in a wide variety of industrial and consumer applications. Here, we report chemical sensitive field-effect-transistors (CS-FETs) based on bulk silicon wafers, wherein an electrostatically confined sub-5 nm thin charge inversion layer is modulated by chemical exposure to achieve a high-sensitivity gas-sensing platform. Using hydrogen sensing as a "litmus" test, we demonstrate large sensor responses (>1000%) to 0.5% H2 gas, with fast response (<60 s) and recovery times (<120 s) at room temperature and low power (<50 MUW). On the basis of these performance metrics as well as standardized benchmarking, we show that bulk silicon CS-FETs offer similar or better sensing performance compared to emerging nanostructures semiconductors while providing a highly scalable and manufacturable platform. PMID- 29455518 TI - Surface Adatom Mediated Structural Transformation in Bromoarene Monolayers: Precursor Phases in Surface Ullmann Reaction. AB - Structural transformations of supramolecular systems triggered by external stimuli maintain great potential for application in the fabrication of molecular storage devices. Using combined ultrahigh vacuum scanning tunneling microscopy, X ray photoemission spectroscopy, and density functional theory calculations, we observed the surface adatom mediated structural transformation from 4,4''-dibromo m-terphenyl (DMTP)-based halogen-bonded networks to DMTP-Cu(Ag) coordination networks on Cu(111) and Ag(111) at low temperatures. The halogen-bonded networks, which were formed on Cu(111) at 97 K and on Ag(111) at 93 K, consist of intact DMTP molecules stabilized by triple Br...Br bonds. The DMTP-Cu(Ag) coordination networks form on Cu(111) at 113 K and on Ag(111) at 103 K. They contain alternatingly arranged intact DMTP molecules and Cu(Ag) adatoms stabilized by weak C-Br...Cu(Ag) coordination bonds. Annealing the DMTP-Ag structure to 333 K leads to the initiation of C-Br bond scission. This observation suggests that the DMTP-Ag coordination network represents the intermediate phase ready for dehalogenation, which is the first step of the surface Ullmann reaction.

AB - In this study, an intelligent pH and ROS dual-responsive drug delivery system based on an apoferritin (AFt) nanocage was prepared. This therapeutic system can specifically self-target 4T1 breast cancer cells by exploiting L-apoferritin receptor SCARA 5, avoiding the nonspecific binding or aggregation of nanoparticles due to the chemical functionalization for targeting. The characteristics of AFt were utilized for the simultaneous delivery of anticancer drug doxorubicin (DOX) and photosensitizer rose bengal (RB). RB exhibited efficient reactive oxygen species (ROS) generation, which can be applied to photodynamic therapy. Meanwhile, the AFt nanocage was prone to undergoing peptide backbone cleavage when oxidized by ROS. Therefore, by combining the intrinsic pH responsive property of AFt, the dual ROS/pH-responsive system was developed. The time and location of drug release can be controlled by the combination of internal and external stimulus, which avoids the incomplete drug release under single stimulus response. The drug release rate increased significantly (from 26.1% to 92.0%) under low-pH condition (pH 5.0) and laser irradiation. More DOX from AFt entered the nucleus and killed the tumor cells, and the cell inhibition rate was up to ~83% (DOX concentration: 5 MUg/mL) after 48 h incubation. In addition, the biodistribution and the in vivo antitumor efficacy (within 14 d treatment) of the nanosystem were investigated in 4T1 breast cancer BALB/c mice. The results indicated that the system is a promising therapeutic agent involving ROS/pH dual response, self-targeting, and chemo-photodynamic therapy.

PMID- 29455521 TI - Self-Assembled Binuclear Cu(II)-Histidine Complex for Absolute Configuration and Enantiomeric Excess Determination of Naproxen by Tandem Mass Spectrometry. AB - Naproxen is one of the most consumed nonsteroidal anti-inflammatory drugs and marketed as S-naproxen since R-naproxen is hepatotoxic. In this study, chiral recognition of naproxen has been investigated by tandem mass spectrometry (MS/MS). Among all diastereomeric complexes formed between naproxen and the examined chiral selectors, including cyclodextrins (alpha/beta/gamma-CD), modified phenylalanines ( N-acetyl-phenylalanine, N-t-butoxycarbonyl phenylalanine, N-9-fluorenylmethyloxycarbonyl-phenylalanine), amino acids (Trp, Phe, Tyr, His), glucose, tartaric acid, and vancomycin, a novel binuclear metal bound diastereomeric complexes [(M(II))2( S/ R-naproxen)(l-His)2-3H]+ (M = Cu, Ni, or Co with Cu being the best) could allow effective identification of the absolute configuration of naproxen and determination of its enantiomeric excess ( ee) through MS/MS analysis. The key candidate structure of [(Cu(II))2( S/ R naproxen)(l-His)2-3H]+ has been revealed by means of collision-induced dissociation, ion mobility mass spectrometry and density functional theory calculations, indicating an interesting and unusual self-assembled compact geometry with the two Cu(II) ions bridged closely together (Cu-Cu distance is 3.04 A) by the carboxylate groups of the two histidines. It was shown that the difference in dissociation efficiency between the two diastereomers was attributed to the interaction between the NH2 bond of the amino group of one histidine and the naphthyl ring of naproxen. The present report is the first to observe and characterize the complex of (Cu(II))2(His)2 with aromatic acid, which could contribute to the chiral recognition of other chiral aromatic acids, design of catalysts based on binuclear copper bound complex, as well as the better understanding of metal ion complexation by His or His-containing ligands. PMID- 29455522 TI - All-MXene-Based Integrated Electrode Constructed by Ti3C2 Nanoribbon Framework Host and Nanosheet Interlayer for High-Energy-Density Li-S Batteries. AB - High-energy-density lithium-sulfur (Li-S) batteries hold promise for next generation portable electronic devices, but are facing great challenges in rational construction of high-performance flexible electrodes and innovative cell configurations for actual applications. Here we demonstrated an all-MXene-based flexible and integrated sulfur cathode, enabled by three-dimensional alkalized Ti3C2 MXene nanoribbon (a-Ti3C2 MNR) frameworks as a S/polysulfides host (a-Ti3C2 S) and two-dimensional delaminated Ti3C2 MXene (d-Ti3C2) nanosheets as interlayer on a polypropylene (PP) separator, for high-energy and long-cycle Li-S batteries. Notably, an a-Ti3C2 MNR framework with open interconnected macropores and an exposed surface area guarantees high S loading and fast ionic diffusion for prompt lithiation/delithiation kinetics, and the 2D d-Ti3C2 MXene interlayer remarkably prevents the shuttle effect of lithium polysulfides via both chemical absorption and physical blocking. As a result, the integrated a-Ti3C2-S/d Ti3C2/PP electrode was directly used for Li-S batteries, without the requirement of a metal current collector, and exhibited a high reversible capacity of 1062 mAh g-1 at 0.2 C and enhanced capacity of 632 mAh g-1 after 50 cycles at 0.5 C, outperforming the a-Ti3C2-S/PP electrode (547 mAh g-1) and conventional a-Ti3C2-S on an Al current collector (a-Ti3C2-S/Al) (597 mAh g-1). Furthermore, the all MXene-based integrated cathode displayed outstanding rate capacity of 288 mAh g-1 at 10 C and long-life cyclability. Therefore, this proposed strategy of constructing an all-MXene-based cathode can be readily extended to assemble a large number of MXene-derived materials, from a group of 60+ MAX phases, for applications such as various batteries and supercapacitors.

AB - Carbonaceous and boron nitride (BN) nanomaterials have similar applications and hydrophobic properties suggesting common release pathways and exposure to bacteria. While high nanomaterial concentrations can be bactericidal or growth inhibitory, little is known regarding bacterial transcriptional responses to non growth-inhibitory nanomaterial concentrations. Here, using one strain of Pseudomonas aeruginosa-a clinically and environmentally important bacterial taxon we analyzed the comparative transcriptomic response to carbonaceous or BN nanomaterials. We show that, at non-growth-inhibitory, equal mass concentrations (10 mg/L), multiwall carbon nanotubes (MWCNTs) induced differential regulation of 111 genes in P. aeruginosa, while graphene, BN, and carbon black caused differential regulation of 44, 26, and 25 genes, respectively. MWCNTs caused the upregulation of genes encoding general stress response (9 genes), sulfur metabolism (15), and transport of small molecules (7) and downregulation of genes encoding flagellar basal-body rod proteins and other virulence-related factors (6), nitrogen metabolism (7), and membrane proteins (12), including a two component regulatory system CzcS/R. Because two-component systems are associated with antibiotic resistance, the antibiotic susceptibility of P. aeruginosa was tested following MWCNT exposure. In MWCNT-treated cultures, the minimal inhibitory concentrations (MICs) of meropenem and imipenem decreased from 0.06 to 0.03 MUg/mL and from 0.25 to 0.125 MUg/mL, respectively. Taken together, whole genome analysis indicated that, in the absence of growth inhibition, nanomaterials can alter bacterial physiology and metabolism. For MWCNTs, such alterations may include downregulation of antibiotic resistance pathways, suggesting that pre-exposure to MWCNTs could potentially render bacteria more susceptible to carbapenems which are often the last resort for the globally concerning, highly antibiotic resistant P. aeruginosa.

AB - This study was conducted to evaluate the use of the phenolic-rich Sonchus oleraceus residue as an environmentally safe approach to induce the nutritive and health-promoting values of common bean ( Phaseolus vulgaris L. cv. Bronco). S. oleraceus shoot residue, at rates of 150 and 300 g m-2, has improved soil fertility via accumulation of soil macronutrients, organic matter, organic carbon, and total phenolics. The growth and yield of bean were significantly increased. Moreover, chemical composition of the treated seeds was significantly altered, whereas higher levels of total antioxidant capacity, proteins, carbohydrates, and most of the individual phenolic acids, flavonoids, vitamins, essential amino acids, and unsaturated fatty acids were recorded. Interestingly, a concentration dependent effect was also observed, for instance, a lower saturated-to-unsaturated fatty acid ratio was only observed in the case of the lower residue rate. These findings recommend the use of S. oleraceus in organic farming of bean to enhance the health benefits of the produced seeds. PMID- 29455525 TI - Graphene Oxide Decorated with Cerium(IV) Oxide in Determination of Ultratrace Metal Ions and Speciation of Selenium. AB - Graphene oxide decorated with cerium(IV) oxide (GO/CeO2) was synthesized and applied in adsorption of several metal ions such as As(III), As(V), Se(IV), Cu(II), and Pb(II) from aqueous samples. The important feature of GO/CeO2 nanocomposite is also its selectivity toward selenite in the presence of selenate. The structure of GO/CeO2 has been proven by microscopic and spectroscopic techniques. The maximum adsorption capacities of GO/CeO2 calculated by Langmuir model toward arsenic, selenium, copper, and lead ions are between 6 and 30 mg g-1. An interesting feature of this adsorbent is its excellent dispersibility in water. Thus, GO/CeO2 nanocomposite is ideal for fast and simple determination of heavy metal ions using dispersive microsolid phase extraction (DMSPE). Moreover, coupling DMSPE with energy-dispersive X-ray fluorescence spectrometry (EDXRF) is extremely beneficial because it allows direct analysis of adsorbent. Thus, the analyte elution step, as needed in many analytical techniques, was obviated. The influence of sample volume and the sorption time as well as the influence of foreign ions and humic acid on the recovery of determined elements are discussed in the paper. The results showed that developed methodology provided low limits of detection (0.07-0.17 MUg/L) and good precision (RSD < 4%). The GO/CeO2 nanocomposite was applied to analysis of real water samples and certified reference materials (CRM) groundwater (BCR-610) and pig kidney (ERM-BB186).

AB - Two interesting new X-ray structures of negative allosteric modulator (NAM) ligands for the mGlu5 receptor, M-MPEP (3) and fenobam (4), are reported. The new structures show how the binding of the ligands induces different receptor water channel conformations to previously published structures. The structure of fenobam, where a urea replaces the acetylenic linker in M-MPEP and mavoglurant, reveals a binding mode where the ligand is rotated by 180 degrees compared to a previously proposed docking model. The need for multiple ligand structures for accurate GPCR structure-based drug design is demonstrated by the different growing vectors identified for the head groups of M-MPEP and mavoglurant and by the unexpected water-mediated receptor interactions of a new chemotype represented by fenobam. The implications of the new structures for ligand design are discussed, with extensive analysis of the energetics of the water networks of both pseudoapo and bound structures providing a new design strategy for allosteric modulators. PMID- 29455527 TI - Mechanical Division of Cell-Sized Liposomes. AB - Liposomes, self-assembled vesicles with a lipid-bilayer boundary similar to cell membranes, are extensively used in both fundamental and applied sciences. Manipulation of their physical properties, such as growth and division, may significantly expand their use as model systems in cellular and synthetic biology. Several approaches have been explored to controllably divide liposomes, such as shape transformation through temperature cycling, incorporation of additional lipids, and the encapsulation of protein division machinery. However, so far, these methods lacked control, exhibited low efficiency, and yielded asymmetric division in terms of volume or lipid composition. Here, we present a microfluidics-based strategy to realize mechanical division of cell-sized (~6 MUm) liposomes. We use octanol-assisted liposome assembly (OLA) to produce liposomes on chip, which are subsequently flowed against the sharp edge of a wedge-shaped splitter. Upon encountering such a Y-shaped bifurcation, the liposomes are deformed and, remarkably, are able to divide into two stable daughter liposomes in just a few milliseconds. The probability of successful division is found to critically depend on the surface area-to-volume ratio of the mother liposome, which can be tuned through osmotic pressure, and to strongly correlate to the mother liposome size for given microchannel dimensions. The division process is highly symmetric (~3% size variation between the daughter liposomes) and is accompanied by a low leakage. This mechanical division of liposomes may constitute a valuable step to establish a growth-division cycle of synthetic cells. PMID- 29455528 TI - Uranyl to Uranium(IV) Conversion through Manipulation of Axial and Equatorial Ligands. AB - The controlled manipulation of the axial oxo and equatorial halide ligands in the uranyl dipyrrin complex, UO2Cl(L), allows the uranyl reduction potential to be shifted by 1.53 V into the range accessible to naturally occurring reductants that are present during uranium remediation and storage processes. Abstraction of the equatorial halide ligand to form the uranyl cation causes a 780 mV positive shift in the UV/UIV reduction potential. Borane functionalization of the axial oxo groups causes the spontaneous homolysis of the equatorial U-Cl bond and a further 750 mV shift of this potential. The combined effect of chloride loss and borane coordination to the oxo groups allows reduction of UVI to UIV by H2 or other very mild reductants such as Cp*2Fe. The reduction with H2 is accompanied by a B-C bond cleavage process in the oxo-coordinated borane. PMID- 29455529 TI - Differentiation of Rums Produced from Sugar Cane Juice (Rhum Agricole) from Rums Manufactured from Sugar Cane Molasses by a Metabolomics Approach. AB - A large set of volatiles (a metabolome) was isolated by SAFE distillation from 25 high priced rums prepared from sugar cane juice (SCJ) and 26 high priced rums manufactured from sugar cane molasses (SCM). The volatile fractions were first analyzed by comprehensive two-dimensional gas chromatography time-of-flight mass spectrometry (GC*GC-TOF-MS), and the "comprehensive template matching fingerprinting" was used to extract the entire features present in the respective set of volatile compounds. After raw data pretreatment, chemometrics was used to locate marker compounds. Following, a sparse-partial-least-squares discriminant analysis ( sPLS-DA) and a partial-least-squares discriminant analysis (PLS-DA) were applied to a training data set for creating a model. The model was validated using leave-one-out cross validation and tested over an independent data set to evaluate its predictive power. The characteristic fingerprint resulted in a 100% correct classification of sugar cane juice rums, thus achieving the first aim of locating markers for these higher quality rums. Then, past-processing identification within the discriminant features was done to characterize 12 significant marker compounds as 1-decanol, gamma-dodecalactone, ethyl 3 methylbutanoate, ethyl nonanoate, 3-furancarboxaldehyde, 1-hexanol, beta-ionone, 2- and 3-methylbutanol, methyl decanoate, 3-octanol, and 2-undecanone. Quantitation of eight selected markers by stable isotope dilution assays confirmed higher concentrations in SCJ compared to SCM and served as the final proof to differentiate both types of spirits. PMID- 29455530 TI - Pd-Doped WO3 Nanostructures as Potential Glucose Sensor with Insight from Electronic Structure Simulations. AB - Herein, we report the results of crystal-structure-dependent nonenzymatic glucose sensing properties of tungsten oxide (WO3) and Pd-doped WO3 nanostructures. The WO3 nanomaterials with orthorhombic, monoclinic, and mixed (ortho + monoclinic) phases were harvested by a facile hydrothermal route by varying the reaction time and subsequent annealing processes. Electrocatalytic activity tests of WO3 samples revealed a 3-fold oxidation peak current enhancement in the monoclinic Pd doped WO3 nanobricks assembly as compared to the orthorhombic WO3 microspheres. Moreover, the Pd-doped WO3 showed a higher glucose-sensing performance in terms of the detection sensitivities of 11.4 MUA MUM-1 cm-2 (linear range: 5-55 MUM) and 5.6 MUA MUM-1 cm-2 (linear range: 65-375 MUM). We have also performed density functional theory simulations for the monoclinic WO3 and Pd-doped WO3 to investigate the charge-transfer and bonding mechanism of glucose on WO3 and Pd doped WO3 surface. As the binding energy of glucose is higher in the case of Pd doped WO3 as compared to bare WO3, it becomes more conducting due to enhancement of density of states near Fermi level; theoretically, we can predict that Pd doped WO3 exhibits a better charge-transfer media compared to bare WO3, resulting in enhanced glucose-sensing performance, which, in turn, qualitatively supports our experimental data. Hence, our experimental data and theoretical insight from the electronic structure simulations conclude that Pd-doped monoclinic WO3 is a potential material for the fabrication of real-time glucose sensors. PMID- 29455531 TI - New Insights on Hydrogen-Bond-Induced Fluorescence Quenching Mechanism of C102 Phenol Complex via Proton Coupled Electron Transfer. AB - The H-bonded coumarin 102 (C102)-phenol complex has been a model system usually used to understand the influence of H-bonding on photophysical processes. Zhao and Han first showed that significant H-bond strengthening occurs in the excited state and proposed the possibility of fluorescence quenching in the complex via internal conversion from a locally excited (LE) state to a low-lying charge transfer (CT) state. Later, we experimentally confirmed fluorescence quenching of C102-phenol complex in a nonpolar solvent (cyclohexane). However, we also found that the existence of the low-lying CT state is ambiguous. Here, we proposed an alternative mechanism for the fluorescence quenching in the H-bonded complex. For this, we evaluate the excited state potential energy surface considering complete H atom-transfer from phenol to C102 along the H-bonding coordinate. Surprisingly, we observed two distinct minima separated by a low-energy barrier. One minimum corresponds to the complex with shortening of H-bond consistent with that of Zhao and Han. On the other hand, the second minimum, which has even lower energy than the first minimum, is likely to be arising from the proton-coupled electron transfer (PCET) process. The nature of the lowest excited state alters from LE to CT type at the second minimum, which may account for the fluorescence quenching phenomena in the system. PMID- 29455532 TI - Anisotropic Self-Oscillating Reaction in Liquid Crystalline Nanosheet Hydrogels. AB - Anisotropic chemical wave propagation of self-oscillating Belousov-Zhabotinsky (BZ) reaction was demonstrated in the poly( N-isopropylacrylamide) gel films embedded with macroscopically aligned liquid crystalline inorganic nanosheets. Although the average propagation rate of chemical wave v was 3.56 mm min-1 in the gels without nanosheets, the propagation was retarded in the gels with 1 wt % of nanosheets: [Formula: see text] = 1.89 mm min-1 and [Formula: see text] = 1.33 mm min-1 along the direction parallel and perpendicular to the nanosheet planes, respectively. Thus, the wave propagation is anisotropic with the anisotropy ratio [Formula: see text] = 1.42 in these gels and the periodic patterns formed by the BZ reaction were concentric ellipses, different from circles seen in isotropic gels. Furthermore, the propagation rate and degree of anisotropy were controllable by nanosheet concentration. These phenomena can be explained that the diffusion of molecules inside the gel is effectively hindered along the direction perpendicular to the nanosheet planes due to the very large aspect ratio of the aligned nanosheets. The present systems will be applicable for anisotropic self-oscillating soft actuators with one-dimensional motions as well as for ideal model system of BZ reactions. PMID- 29455533 TI - Effect of Dietary Protein Level on the Expression of Proteins in the Gastrointestinal Tract of Young Pigs. AB - The objective of this research is to investigate the effect of protein level on proteins expression in the gastrointestinal tract of young pigs. Eighteen piglets (Duroc * Landrace * Yorkshire) were weaned at 28 days of age and randomly assigned to three diets with 20%, 17%, and 14% CP level, and four essential amino acids, Lys, Met, Thr, and Trp, in three diets met the requirements of weaned piglets. The experimental period lasted 45 days. Compared with the control (20% CP level), the average daily feed intake, the average daily gain, and gain feed ratio of the 17% CP group did not decrease ( P > 0.05), but those of 14% CP group decreased ( P < 0.05). The proteomics profiles result of three tissues (gastric antrum, duodenum, and jejunum) showed that, compared with the control, the immune system, protein digestion and absorption, lipid or carbon digestion and absorption, etc. were up-regulated in 17% CP group, while most of them were down regulated in 14% CP group. Amino acids metabolism of gastric, pancreatic secretion of duodenum or steroid hormone biosynthesis of jejunum was down regulated in the 17% CP group, but the lipid metabolism was up-regulated in the 14% CP group. Six proteins were selected for identification by Western-blot, and their changes had the same trend as the proteomics results. The protein level decreased from 20% to 17%, the growth performance was not affected, while the nutrient digestion and absorption or the immune function were improved, which implied that 17% protein level maybe benefit for nutrients absorption of pigs. PMID- 29455534 TI - Rate-Limiting O-O Bond Formation Pathways for Water Oxidation on Hematite Photoanode. AB - Photoelectrochemical (PEC) water oxidation has attracted heightened interest in solar fuel production. It is well accepted that water oxidation on hematite is mediated by surface trapped holes, characterized to be the high valent -Fe?O species. However, the mechanism of the subsequent rate-limiting O-O bond formation step is still a missing piece. Herein we investigate the reaction order of interfacial hole transfer by rate law analysis based on electrochemical impedance spectroscopy (EIS) measurement and probe the reaction intermediates by operando Fourier-transform infrared (FT-IR) spectroscopy. Distinct reaction orders of ~1 and ~2 were observed in near-neutral and highly alkaline environments, respectively. The unity rate law in near-neutral pH regions suggests a mechanism of water nucleophilic attack (WNA) to -Fe?O to form the O-O bond. Operando observation of a surface superoxide species that hydrogen bonded to the adjacent hydroxyl group by FT-IR further confirmed this pathway. In highly alkaline regions, coupling of adjacent surface trapped holes (I2M) becomes the dominant mechanism. While both are operable at intermediate pHs, mechanism switch from I2M to WNA induced by local pH decrease was observed at high photocurrent level. Our results highlight the significant impact of surface protonation on O-O bond formation pathways and oxygen evolution kinetics on hematite surfaces. PMID- 29455535 TI - Antioxidative Nanoparticles Significantly Enhance Therapeutic Efficacy of an Antibacterial Therapy against Listeria monocytogenes Infection. AB - Acute inflammatory conditions such as sepsis lead to fatal conditions, including multiple organ failure. Several treatments such as steroidal anti-inflammatory drugs are currently being investigated in order to decrease the blood cytokine level, which increases remarkably. However, any of these therapeutic treatments are not always reliable and effective; none have drastically improved survival rates, and some have mostly ended with failure. Reactive oxygen species (ROS) are signaling molecules responsible for the production of cytokines and chemokines that can mediate hyperactivation of the immune response called cytokine storm. In addition to the above-mentioned agents, various antioxidants have been explored for the removal of excess ROS during inflammation. However, the development of low-molecular-weight (LMW) antioxidants as therapeutic agents has been hampered by several issues associated with toxicity, poor pharmacokinetics, low bioavailability, and rapid metabolism. In the present study, we aimed to overcome these limitations through the use of antioxidative nanoparticles possessing 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) which are covalently conjugated to polymer. Although treatment with antioxidative nanoparticles alone did not eliminate bacteria, combined treatment with an antibacterial agent was found to significantly improve survival rate of the treated mice as compared to the control group. More importantly, the antioxidative nanoparticles reduced oxidative tissue injury caused by the bacterial infection. Thus, our findings highlighted the effectiveness of combination treatment with antioxidative nanoparticles and an antibacterial agent to prevent severe inflammation caused by bacterial infection. PMID- 29455536 TI - Resveratrol's Hidden Hand: A Route to the Optical Detection of Biomolecular Binding. AB - Resveratrol is a stilbenoid phytoalexin with promising myriad health benefits predominantly contributed by the trans ( E) diastereomeric form. A recent study has implicated the cis ( Z) diastereomer in human health. This stereoisomer binds with high affinity to human tyrosyl-tRNA synthetase, initiating a downstream cascade that promotes the expression of genes associated with the cellular stress response. We discovered that the nonplanar structure of the cis-resveratrol conformer possesses certain chiral signals in its simulated vibrational circular dichroism (VCD) and Raman optical activity (ROA) spectra. These features may be used for the optical detection of the binding event and in understanding the more diversified biological roles of trans-resveratrol over cis-resveratrol. We use a density functional theory model, which is validated against the known results for the E diastereomer. The Z diastereomer is significantly nonplanar and can exist in two helical atropisomeric forms. These forms exchange rapidly in solution, but only one is observed to bind with the synthetase. This suggests that the binding may generate an enantiomeric excess, leading to detectable changes in the vibrational optical activity spectra. We identify candidate features at 998, 1649, and 1677 cm-1 in the ROA and at 1642 and 3834 cm-1 in the VCD spectra of Z resveratrol that may be useful for this purpose.

Mechanoresponsive vesicles could provide an alternative way to release active compounds triggered by the basic physics of the human body. 1,3-Diamidophospholipids with C16 tails proved to be an effective building block for mechanoresponsive vesicles, but their low main phase transition temperature prevents an effective application in humans. As the main phase transition temperature of a membrane depends on the fatty acyl chain length, we synthesized a C17 homologue of a 1,3 diamidophospholipid: Rad-PC-Rad. The elevated main phase transition temperature of Rad-PC-Rad allows mechanoresponsive drug delivery at body temperature. Herein, we report the biophysical properties of Rad-PC-Rad monolayer and bilayer membranes. Rad-PC-Rad is an ideal candidate for advancing the concept of physically triggered drug release.

AB - OBJECTIVES: The present study was aimed at comparing tetanus toxoid (TT)-loaded chitosan nanoparticles with aluminum hydroxide as a common vaccine adjuvant. BACKGROUND: Tetanus remains to be a major public health problem. Nanoparticles have been extensively used as immune adjuvants. Tetanus toxoid (TT) encapsulated in chitosan nanoparticles is considered to be a promising tetanus vaccine candidate. METHODS: TT-loaded chitosan nanoparticles were prepared by the ionic gelation method. The nanoparticles were studied by SEM for their size and morphology. In vivo study was conducted to evaluate the immunity response using mice divided into 4 groups and injected with encapsulated toxoid. The immune responses were then measured using indirect ELISA. RESULTS: The purity and integrity of antigen were confirmed by SDS-PAGE electrophoresis. The size of nanoparticles was estimated at 100 nm. As a result, the IgG antibody levels were 1.9, 1.76, and 0.87 in chitosan nanoparticles, aluminum hydroxide, and TT alone groups, respectively. Also, the immune responses were significantly higher in immunized groups compared to control groups vaccinated with free adjuvant vaccines (p < 0.05). CONCLUSIONS: The quality and efficacy of toxoid-loaded chitosan nanoparticles were reasonable. It enhanced the immune responses as much as aluminum hydroxide adjuvant does and thus may be a good alternative candidate (Tab. 1, Fig. 3, Ref. 16). PMID- 29455540 TI - CdS nanoparticles of different lengths induce differential responses in some of the liver functions of mice. AB - Cadmium sulfide nanoparticles (CdS NPs) are one of important nanoparticle materials which are widely used in photoelectric production, but their potential health hazard to the liver is not clear. This study is aimed at exploring the possible mechanisms of liver injury induced by CdS NPs. Male mice were treated with nanoparticles of 110-130 nm and 80-100 nm cadmium sulfide. The main methods were based on detecting the vigor of superoxide dismutase (SOD) and glutathione (GSH), and content of malondialdehyde (MDA) in both blood and liver tissues as well as on observing the pathological changes in liver tissue. CdS NPs suppressed the activity of SOD and GSH, and increased the serum MDA content (p < 0.05); both effects were observed together in liver tissues of 80-100 nm group (p < 0.05) and were accompanied by an obviously inflammatory response. CdS NPs induced oxidative damage and inflammatory response in liver tissue, which may be an underlying mechanism for its pulmonary toxicity. Additionally, the toxicity of CdS NPs was closely related to the size of nanoparticles. Pathological results showed that the hepatotoxicity of shorter CdS NPs is greater than that of longer CdS NPs (Tab. 6, Fig. 3, Ref. 20).

AB - OBJECTIVES: This study is aimed to determine the effect of ozone therapy in neonatal rats with experimentally induced hypoxic ischemic brain injury (HIBI). METHODS: The study included 7-d-old male Wistar rats that were randomized to the sham, control, ozone 1, and ozone 2 groups. All rats except those in the sham group were kept in a hypoxia chamber, and then the rats in the control group were given 0.5 mL of saline. Those in the ozone 1 group were given ozone 1 mg kg-1 intraperitoneally, and those in the ozone 2 group were given ozone 2 mg kg-1 intraperitoneally. RESULTS: There were significantly fewer apoptotic neurons in the right hemispheres of the rats in the ozone 1 and ozone 2 groups than in the control group (p < 0.001 and p < 0.001, respectively). There were significantly fewer apoptotic neurons in the right hemispheres of the rats in the ozone 2 group than in the ozone 1 group (p < 0.001). Morris Water Maze (MWM) test results were similar in the ozone 2 and sham groups. CONCLUSIONS: The present study's findings show that ozone therapy reduced neuronal apoptosis and improved cognitive function in neonatal rats with experimentally induced HIBI (Tab. 2, Ref. 30).

AB - BACKGROUND AND OBJECTIVES: Human serum albumin (HA) is a unique multifunctional protein with neuroprotective properties. We aimed to delineate the mechanisms of HA-induced neuroprotection, supresses inflammatory response and lipid peroxidation after spinal cord injury (SCI). METHODS AND STUDY DESIGN: Adult female Wistar rats weighing 210-250 g were used for the study. The rats were randomly and blindly allocated into five groups. The one-way analysis of variance (ANOVA) for parametric data and Shapiro-Wilk test was used for evaluating the normal distribution of the variables. Kruskal-Wallis for nonparametric data was used to compare groups. Electron and light microscopies were used to demonstrate ultrastructural changes in spinal cord. RESULTS: The HA group was significantly different from all the other groups (p < 0.05). Both MPSS and HA treatments decreased the MPO significantly. HA treatment decreased the lipid peroxidation. HA treatment prevented the worsening of clinical results. In the HA treatment group, the ultrastructure was protected significantly. The neuronal bodies and axonal structures were normal except for some limited edematous spaces. CONCLUSIONS: HA improves early clinical results, protects spinal cord ultrastructure, and decreases MPO and LPO levels after spinal cord contusion injury (Tab. 3, Fig. 3, Ref. 39).

The research team studied Leucine in a rat model in vivo. The study took place in the medical and surgical experimental research center at the Eskisehir Osmangazi University in Eskisehir, Turkey. The animals were Wistar albino male rats. RESULTS: Group I, the sham group, was administered phosphate buffered saline (PBS) after laparotomy. After 70 % PH procedure, group II, III, IV, and V received single intraperitoneal doses of PBS, valine, glutamine, and leucine amino acids, respectively. At hour 6 after PH, expressions of 88 genes involving in NF-kappaB signal pathway were examined by RT PCR mini array method in the liver tissue specimen. Fold values below 0.5 and above 2 were regarded as significant. CONCLUSIONS: Our results suggested that valine, glutamine, and leucine amino acids may alter expressions of the genes of NF-kappaB signal pathway. In addition, among these amino acids, glutamine and valine proved to be much more effective on NF-kappaB signal pathway after the PH (Tab. 1, Ref. 41). PMID- 29455544 TI - Heart failure affects liver morphology and function. What are the clinical implications? AB - Liver dysfunction in heart failure is common and usually clinically significant, especially in patients with advanced or severe acute heart failure. Lesions are caused by an impaired hepatic circulation due to congestion and hypoperfusion. Congestive lesions are more common and typically manifested by painful hepatomegaly and increased direct bilirubin and alkaline phosphatase. The inferior vena cava and hepatic veins are usually dilated. Congestive lesions are characterized by dilatation of the central vein with fibrotic changes in the surrounding areas on histological examination. Isolated ischaemic lesions are rare and occur due to severe and prolonged ineffective perfusion, often accompanied by hypoxemia. Ineffective perfusion is reflected by an increase in total bilirubin and significantly increased transaminase levels. The prognosis of ischaemic lesions without an adequate treatment of the cause of hypoperfusion is poor. Increased levels of bilirubin and liver function tests, as well as signs of impaired liver proteosynthetic function, are associated with a poor prognosis. Knowledge of the phenotypes of hepatic lesions in heart failure is important to select the appropriate treatment for an acute decompensation. Changes in biochemical markers, hepatic perfusion or stiffness of the liver can be used to evaluate the effectiveness of diuretic treatment and achieve euvolemic status in the patients with heart failure (Tab. 1, Fig. 3, Ref. 28). PMID- 29455545 TI - Role of autophagy in the progress of coronary total occlusion. AB - OBJECTIVE: In this study, we measured the level of autophagy enzyme in patients with coronary artery disease (CAD) and investigated whether the role of autophagy existed in the progress of coronary collateral and coronary total occlusion (TO). METHODS: Overall, 115 participants were included in this study. They were divided into the three groups: group 1: patients had chronic TO (n=49); group 2: patients had acute TO such as myocardial infarction (n=36); and group 3: participants were normal controls (n=30). The enzyme-linked immunosorbent assay (ELISA) kit for autophagy-related protein 5 (ATG5) in the plasma was studied for these three groups. RESULTS: Autophagy levels were significantly different between the groups (13.7+/-5.3, 11.7+/-3.4, and 7.5+/-3 ng/mL, respectively; p<0.001). In the subgroup analysis, we found significant positive correlations between the level of autophagy and Rentrop score in the Group 1 (r=0.463, p<0.001). CONCLUSION: In the present study, autophagy levels were higher in the patients with CAD than in healthy controls. In addition, serum autophagy levels showed a significant positive correlation with the Rentrop score. An increased autophagy level may be considered an important activator and marker of the atherosclerotic inflammatory process in CAD (Tab. 1, Fig. 2, Ref. 20).

AB - OBJECTIVE: The aim of the study was to observe the influence of 11-days complete water fasting (WF) and regeneration diet (RD) on renal function, body weight, blood pressure and oxidative stress. BACKGROUND: Therapeutic WF is considered a healing method. METHODS: Ten volunteers drank only water for 11 days, followed by RD for the next 11 days. Data on body weight, blood pressure, kidney functions, antioxidants, lipid peroxidation, cholesterols, triacylglycerols and selected biochemical parameters were obtained. RESULTS: WF increased uric acid and creatinine and decreased glomerular filtration rate. After RD, the parameters were comparable to baseline values. Urea was not affected. Lipid peroxidation (TBARS) decreased and maintained stable after RD. Fasting decreased alpha tocopherol and increased gamma-tocopherol, no significant changes were found after RD. Coenzyme Q10 decreased after RD. HDL-cholesterol decreased in WF. Total and LDL-cholesterol decreased after RD. Other biochemical parameters were within the range of reference values. CONCLUSIONS: The effect of the complete fasting on kidney function was manifested by hyperuricemia. Renal function was slightly decreased, however maintained within the reference values. After RD, it returned to baseline values. The positive effect of the complete water fasting was in the reduction of oxidative stress, body weight and blood pressure (Tab. 3, Ref. 25). PMID- 29455547 TI - Evaluation of fractalkine (FKN) and secreted frizzled-related protein 4 (SFRP-4) serum levels in patients with prediabetes and type 2 diabetes. AB - OBJECTIVE: The objective of this study is to compare serum levels of FKN and SFRP 4 in patients with normal glucose tolerance (NGT), impaired glucose tolerance (IGT), and type 2 diabetes mellitus (T2DM). METHODS: A total of 152 patients presented to the endocrinology outpatient clinic of our hospital were included in the study. Eighty-two patients with a history of T2DM were assigned to the T2DM group. IGT (n = 34) and NGT (n = 36) groups included the patients who received oral glucose tolerance test outcomes. RESULTS: Serum FKN levels were significantly higher in the IGT and T2DM groups compared to the NGT group (p < 0.001 and p < 0.001, respectively). Serum SFRP-4 levels were significantly higher in the T2DM group compared to the IGT and NGT groups (p = 0.001 and p = 0.004, respectively). A significant correlation was observed between FKN and fasting glucose levels. SFRP-4 was significantly correlated with fasting glucose, HbA1c, and triglyceride levels. CONCLUSION: To our knowledge, increased FKN levels in patients with IGT were demonstrated for the first time in this study. The results of our study support the opinion that FKN and SFRP-4 may contribute to the pathogenesis of T2DM (Tab. 1, Fig. 3, Ref. 23). PMID- 29455548 TI - The effects of smoking on neutrophil/lymphocyte, platelet/ /lymphocyte ratios. AB - OBJECTIVE: The aim of this study was to compare the Neutrophil to Lymphocyte ratio (NLR), Platelet to Lymphocyte ratio (PLR) and Mean Platelet Volume to Platelet (MPV/Plt) ratio of smokers and non-smokers. METHODS: Two hundred smokers and two hundred non-smoking healthy volunteers were enrolled in this study. Sociodemographic data and hematologic parameters of all patients were recorded. NLR, PLR and MPV/Plt ratios were calculated. RESULTS: The mean age of the case group was 35.88 +/- 10.56 and the mean age of the control group was 38.97 +/- 10.56. 80 % (n = 160) of the smokers were male and 20 % (n = 40) were female. 27.5 % (n = 55) of the control group were male and 72.5 % (n = 145) were female. The smoker group had higher NLR and MPV/Plt ratio (p < 0.05). PLR was significantly higher for the non-smoker group (p < 0.05). CONCLUSION: As a result of our study, an increase in the NLR which is used as a systemic inflammatory marker, a decrease in the PLR and an increase in the MPV/Plt ratio which indicates thromboembolism risk were found for the smoker group (Tab. 3, Ref. 32). PMID- 29455549 TI - Multiple endocrine neoplasia 2A (MEN 2A) syndrome. AB - INTRODUCTION: In the MEN 2A syndrome, which is the most common of the three types of MEN, three endocrine systems are affected simultaneously or subsequently by the development of tumours manifested by medullary thyroid gland carcinoma, pheochromocytoma (often bilateral) and hyperparathyroidism. MATERIAL AND METHODS: 27 patients from 3 families affected by MEN 2A syndrome were examined clinically (by detecting the effects of catecholamine overproduction), biochemically (screening for metanephrine and normetanephrine in the serum), visualization (CT, MRI, MIBG, PET CT) and some of them also genetically (DNA fragment analysis obtained by PCR amplification). RESULTS: Familial incidence of pheochromocytoma was confirmed in 10 patients (4 males, 5 females and one girl) aged 6 to 54 years (average 22.8 years) . In 5 patients, the pheochromocytoma occurred on both sides, in one patient, with genetically proved MEN 2A syndrome, only one adrenal gland was affected by pheochromocytoma. In 10 patients, mutations were detected in the exon 10, 11 and 16 RET of the proto-oncogene in the centromeric region of the 10th chromosome. After proper preparation, 5 patients underwent bilateral adrenalectomy (unilateral adrenalectomy in one patient). Histological examination of the removed tumours in all cases excluded the malignant pheochromocytoma.The first of the operated patients (54 yr) died after surgery for cardiovascular failure. Others have lived 5 to 15 years after bilateral adrenalectomy without signs of local recurrence of the disease, and have no clinical signs of over production of catecholamines. CONCLUSION: Bilateral pheochromocytoma and thyroid carcinoma are indications for detailed clinical and genetic examination of all family members. Bilateral adrenalectomy with lifetime supplementation of adrenal hormones is indicated in symptomatic patients and/or patients asymptomatic with tumours larger than 3 cm in diameter (Tab. 1, Fig. 11, Schema 1, Ref. 31).

AB - 5-Aza-2'-deoxycytidine (AzaD), also known as Decitabine, is a deoxycytidine analog that is typically used to activate methylated and silenced genes by promoter demethylation. However, a survey of the scientific literature indicates that promoter demethylation may not be the only (or, indeed, the major) mechanism by which AzaD affects gene expression. Regulation of gene expression by AzaD can occur in several ways, including some that are independent of DNA demethylation. Results from several studies indicate that the effect of AzaD on gene expression is highly context-dependent and can differ for the same gene under different environmental settings. This may, in part, be due to the nature of the silencing mechanism(s) involved - DNA methylation, repressive histone modifications, or a combination of both. The varied effects of AzaD on such context-dependent regulation of gene expression may underlie some of the diverse responses exhibited by patients undergoing AzaD therapy. In this review, we describe the salient properties of AzaD with particular emphasis on its diverse effects on gene expression, aspects that have barely been discussed in most reviews of this interesting drug.

PMID- 29455553 TI - Correlates of missed clinic visits among youth living with HIV. AB - Youth living with HIV (YLH) have significant problems with attending their medical appointments. Poor attendance, consequently, predicts viral non suppression and other negative health outcomes. To identity targets of intervention, this cross-sectional study examined correlates of past-year missed clinic visits among YLH (N = 2125) attending HIV clinics in the United States and Puerto Rico. Thirty-six percent of YLH missed two or more visits in the past year. Several factors were associated with missed visits in our regression model. Among sociodemographic characteristics and HIV disclosure status, females (adjusted odds ratio [OR] = 1.63, compared to males), Black YLH or YLH of mixed racial heritage (AORs = 1.76, 1.71, respectively, compared to White YLH), YLH with an unknown route of infection (AOR = 1.86, compared to YLH with perinatal infection), and YLH endorsing HIV disclosure (AOR = 1.37, compared to YLH not endorsing disclosure) were at greater risk for missed visits. Among behavioral health risks, YLH who endorsed marijuana use (AOR = 1.42), frequent other drug use (AOR = 1.60), or a history of incarceration (AOR = 1.27) had greater odds of missed visits than youth not endorsing these risks. Finally, two social-cognitive resources emerged as protective factors: adherence self-efficacy (AOR = .28) and social support (AOR = .88). We discuss how providers working with YLH can improve this population's retention outcomes. PMID- 29455555 TI - Employment status is related to sleep problems in adults with autism spectrum disorder and no comorbid intellectual impairment. AB - Both sleep problems and unemployment are common in adults with autism spectrum disorder; however, little research has explored this relationship in this population. This study aimed to explore factors that may be associated with the presence of an International Classification of Sleep Disorders-Third Edition defined sleep disorder in adults with autism spectrum disorder (IQ > 80). A total of 36 adults with autism spectrum disorder and 36 controls were included in the study. Participants completed a 14-day actigraphy assessment and questionnaire battery. Overall, 20 adults with autism spectrum disorder met the International Classification of Sleep Disorders-Third Edition criteria for insomnia and/or a circadian rhythm sleep-wake disorder, while only 4 controls met criteria for these disorders. Adults with autism spectrum disorder and an International Classification of Sleep Disorders-Third Edition sleep disorder had higher scores on the Pittsburgh Sleep Quality Index and were more likely to be unemployed compared to adults with autism spectrum disorder and no sleep disorder. The findings demonstrate, for the first time, that sleep problems are associated with unemployment in adults with autism spectrum disorder. Further research exploring the direction of this effect is required; sleep problems that have developed during adolescence make attainment of employment for those with autism spectrum disorder difficult, or unemployment results in less restrictions required for optimal and appropriate sleep timing. PMID- 29455554 TI - Synthesis, antitumour and antioxidant activities of novel alpha,beta-unsaturated ketones and related heterocyclic analogues: EGFR inhibition and molecular modelling study. AB - New alpha,beta-unsaturated ketones 4a,b; 5a-c; and 6a,b; as well as 4-H pyran 7; pyrazoline 8a,b; isoxazoline 9; pyridine 10-11; and quinoline-4-carboxylic acid 12a,b derivatives were synthesized and evaluated for in vitro antitumour activity against HepG2, MCF-7, HeLa, and PC-3 cancer cell lines. Antioxidant activity was investigated by the ability of these compounds to scavenge the 2,2'-azinobis(3 ethylbenzothiazoline-6-sulfonic acid) radical cation (ABTS*+). Compounds 6a, 6b, 7, and 8b exhibited potent antitumour activities against all tested cell lines with [IC50] ?5.5-18.1 uMU), in addition to significantly high ABTS*+ scavenging activities. In vitro EGFR kinase assay for 6a, 6b, 7, and 8b as the most potent antitumour compounds showed that; compounds 6b, and 7 exhibited worthy EGFR inhibition activity with IC50 values of 0.56 and 1.6 uM, respectively, while compounds 6a and 8b showed good inhibition activity with IC50 values of 4.66 and 2.16 uM, respectively, compared with sorafenib reference drug (IC50 = 1.28 uM). Molecular modelling studies for compounds 6b, 7, and 8b were conducted to exhibit the binding mode towards EGFR kinase, which showed similar interaction with erlotinib. PMID- 29455556 TI - Conventional vs Computer-Assisted Stereoscopic Ultrasound Needle Guidance for Renal Access: A Randomized Crossover Bench-Top Trial. AB - PURPOSE: Ultrasound (US) guidance during renal access and mass biopsy reduces radiation exposure, but can be technically challenging. A needle guidance system might simplify these procedures. The purpose of this randomized crossover trial was to compare conventional and computer-assisted US needle guidance systems for renal access and mass biopsy. MATERIALS AND METHODS: Seventy-one subjects were randomized to perform renal access or mass biopsy on a phantom using conventional and computer-assisted US guidance in a crossover study design. The primary outcome was success rate including subgroup analysis by experience level. Secondary outcomes included total procedure time, time to hit target, number of course corrections, and total punctures. In addition, subjective preferences of participants were also collected. RESULTS: Procedure success rate was higher with the computer-assisted US than with conventional US for both novice (98.0% (48/49) vs 81.6% (40/49); p < 0.001) and experienced US users (100% (22/22) vs 81.8% (18/22); p < 0.001). Computer-assisted US significantly shortened the total procedure time (94.0 seconds vs 192.9 seconds; p <= 0.001), time required to hit the target (62.5 seconds vs 121.6 seconds; p <= 0.001), and the number of course corrections (0.56 vs 2.89; p < 0.001) compared with conventional US. Computer assisted US did not significantly reduce the number of needle punctures (1.75 vs 2.39; p = 0.132). Seventy-three percent of subjects preferred the computer assisted US system. CONCLUSION: A computer-assisted needle guidance system increases effective US targeting for renal access and mass biopsy for novice and experienced users. PMID- 29455557 TI - The effects of rutin on cisplatin induced oxidative retinal and optic nerve injury: an experimental study. AB - AIM: To determine the role of rutin in prevention of cisplatin induced retinal and optic nerve injury in an experimental study. MATERIALS AND METHODS: Totally 18 albino Wistar male rats were assigned into three groups, as follows: healthy controls (HC group), only cisplatin administered group for 14 days (CIS group), and rutin + cisplatin administered group for 14 days (RC group). Blood samples were obtained from animals just before the scarification. Serum malondialdehyde (MDA), myeloperoxidase (MPO), total glutathione (tGSH), superoxide dismutase (SOD), interleukin 1 beta (IL-1beta) and tumour necrosis factor alpha (TNF-alpha) levels were investigated. The eyes were enucleated for histopathological evaluations of retina and optic nerve. RESULTS: MDA, MPO, IL-1beta and TNF-alpha levels were statistically significantly higher (p < 0.001) in CIS group compared with other two groups while tGSH and SOD levels were statistically significantly lower (p < 0.001). Regarding these parameters, in CIS group MDA, MPO, IL1beta and TNF-alpha levels were statistically significantly increased with cisplatin administration and giving rutin concomitantly with cisplatin prevented this increase. On the other hand, tGSH and SOD levels were statistically significantly decreased with cisplatin administration and giving rutin concomitantly with cisplatin prevented this decrease. In qualitative analyses of histopathological findings of retina and optic nerve; the results of RC group were similar with the results of healthy controls; but there was statistically significant differences between CIS group and other two groups (p < 0.001). CONCLUSIONS: Concomitant rutin administration may prevent the detrimental effects of cisplatin on lipid peroxidation, oxidative stress and inflammation markers and may also avert the histopathological damage on retina and optic nerve. Further studies are warranted to determine the effects of cisplatin and rutin on eye. PMID- 29455558 TI - Investigational immunosuppressants in early-stage clinical trials for the treatment of multiple sclerosis. AB - INTRODUCTION: Multiple sclerosis (MS) is a chronic demyelinating disease of the central nervous system with an immune mediated pathogenesis. Several therapies that suppress or modulate diverse immune system functions have been used for decades with the aim of modifying the disease course. However, these treatments have either limited efficacy or potentially serious adverse events that prevent first-line use on large scale. Areas covered: The aim of the present article is to review ongoing or recently completed clinical trials investigating immunosuppressive drugs for MS. The websites clinicaltrials.gov, clinicaltrialsregister.eu, and pubmed.gov were searched for phase 1, phase 2, and phase 3 trials starting from 2012. Twelve drugs were identified, including seven monoclonal antibodies and five small molecules. Expert opinion: Current or recently completed trials of immunosuppressants for MS are mainly proof-of concept studies enrolling patients with relapsing disease and using efficacy endpoints based on magnetic resonance imaging measures of inflammatory activity. Sphingosine 1-phosphate receptor modulators and B-cell depleting therapies represent the most commonly investigated drugs, suggesting that mechanisms of action that have already shown promise for MS treatment are being exploited to find new therapies with improved safety, tolerability, and convenience of dosing. Clinical trials of immunosuppressants for progressive MS are largely lacking.

AB - BACKGROUND: Although tuberculosis screening guidelines for psoriasis patients on TNF inhibitors exist, few studies have reported the prevalence of latent tuberculosis infection (LTBI) and conversion rates in this population. OBJECTIVE: To determine the incidence of LTBI and active tuberculosis in patients with psoriasis receiving TNF inhibitor therapy. METHODS: A total of 138 patients were included in our retrospective study of patients treated from September 2004 to September 2017. Tuberculin skin test was considered positive with an induration of greater than 5 mm. History of Bacillus Calmette-Guerin vaccination, follow-up tests and prophylaxis were recorded. RESULTS: Among 99 biologic-naive patients, 14 had LTBI before starting biologic therapy and five developed LTBI during TNF inhibitor therapy. One biologic-naive patient developed LTBI, then active tuberculosis. Among 39 non-biologic-naive patients, three had LTBI before starting any biologic therapy, and one developed LTBI during treatment. LIMITATIONS: Limitations include small sample size and limited information documented in the medical chart. CONCLUSIONS: LTBI appears to be prevalent among psoriasis patients. Screening for LTBI in patients on biologics may reduce risk of active tuberculosis; however, current methods may not be fully effective. Clinicians may need to use other tools including risk factor assessment to fully evaluate risk. PMID- 29455562 TI - Spatiotemporal Characteristics of the HIV-1 CRF02_AG/CRF63_02A1 Epidemic in Russia and Central Asia. AB - Eastern European countries, including Russia, Ukraine, and other former Soviet Union (FSU) countries, have experienced a human immunodeficiency virus (HIV) epidemic spreading mostly among people who inject drugs (PWID). We aimed to investigate the origin and the dispersal patterns of HIV-1 CRF02_AG in Russia and other FSU countries. We studied 136 CRF02_AG sequences originating from Russia, and FSU countries along with a globally sampled dataset of 3,580 CRF02_AG sequences. Maximum-likelihood phylogeny reconstruction with bootstrap evaluation was conducted in RAxML. Bayesian phylogeographic analysis was performed in BEAST v1.8 using the discrete trait model. We found that all CRF02_AG sequences from Russia and other FSU countries formed a single monophyletic cluster within CRF02_AG radiation. The Russian/FSU clade was classified as CRF63_02A1. Sequences from the FSU countries clustered further within distinct subclades (two from Russia, three from Uzbekistan, and one Kazakhstan) according to the geographic origin of sampling. Molecular clock analysis revealed that the time to the most recent common ancestor (tMRCA) of the CRF63_02A1 epidemic was in 1996 [95% higher posterior density (95% HPD): 1992-1999], while for the two Russian subclades, tMRCA was estimated in 2003 (95% HPD: 2001-2004) and in 2007 (95% HPD: 2005 2008). Phylogeographic analysis suggested that the potential origin of the epidemic was in Uzbekistan. Early dispersal of CRF63_02A1 occurred in Kazakhstan and Uzbekistan and thereafter the epidemic spread to Russia. Notably, spillover transmissions to Russia kept occurring from both countries. Previous studies have shown that Russia and Ukraine have provided the source for the PWID-driven, HIV-1 subtype-A epidemic, spreading across the FSU countries (AFSU). In great contrast, CRF63_02A1 established an epidemic in central Asia (Uzbekistan and Kazakhstan), from where it subsequently disseminated to Russia. Our study suggests that cross border transmissions among PWID occur bidirectionally between Russian and other FSU populations. These results are of public health importance and suggest that prevention actions have to be reinforced in this area to assist the management of high-risk practices.

PMID- 29455564 TI - Measurement uncertainty of platelet concentration using the Sysmex XN automated hematology analyzer. AB - We estimated the measurement uncertainty (MU) of platelet concentration measured using the Sysmex XN system with two reference platelet counting methods described by DIN 58932-5 (PTB method) and the International Council for Standardization in Haematology (ICSH method). Ten blood samples were used to estimate and compare the MU of the XN system, and 30 samples were used to compare the methods. The standard uncertainty of the reference method was significantly higher for the ICSH method; the PTB method showed higher platelet concentrations than the ICSH method. When applying different methods with the XN system, optic counting showed higher MU compared to the other methods. There was good correlation among the two reference methods and three automated platelet-counting methods. We evaluated the MU in platelet concentrations measured using an automated hematology analyzer. Our results suggest that using the PTB method for calculating MU of the automated hematology analyzer is superior to the ICSH method because of its lower standard uncertainty. PMID- 29455565 TI - Pulsed dye laser versus intense pulsed light in melasma: a split-face comparative study. AB - BACKGROUND: Recent reports suggest that melasma may have a vascular component. Vascular targeting lasers and light treatment can be a therapeutic option that will provide benefits to the patients. OBJECTIVES: To compare the efficacy and tolerability of pulsed dye laser (PDL) and intense pulsed light in treatment of melasma. PATIENTS AND METHODS: Twenty-eight Egyptian female patients with melasma were treated with PDL on the right hemiface (Group A) and with the intense pulsed light on the left hemiface (Group B). Clinical assessment was performed according to the hemifacial modified Melasma Area and Severity Index score (mMASI). Tissue biopsies were taken from patients for immunohistochemical staining with vascular endothelial growth factor (VEGF) antibody. RESULTS: The hemifacial mMASI score was significantly reduced after treatment in studied groups with no statistically significant difference. Intense pulsed light (IPL) group showed higher efficacy of treatment than PDL group in the epidermal melasma and in melasma lesions which had a vascular component. The expression level and intensity score of VEGF were significantly reduced after treatment in both groups. CONCLUSIONS: Both PDL and IPL were effective and safe treatment modalities for lightening of melasma. VEGF can be proved as a possible mechanism underlying the action of both PDL and IPL on melasma. PMID- 29455566 TI - 'He supported me 100%': Mexican-immigrant fathers, daughters, and adolescent sexual health. AB - OBJECTIVE: First and second generation Mexican-origin adolescents in the U.S. face social and economic disadvantage and sexual health disparities. Although fathers can support child and adolescent development, the literature has portrayed Mexican-origin immigrant fathers as emotionally distant and sexist. This study aims to treat migration as a social determinant of health to examine father-daughter relationships and adolescent sexual health in Mexican-origin immigrant families. METHODS: Integrating qualitative data from life history interviews with 21 Mexican-origin young women in immigrant families with quantitative data on first and second generation Mexican-origin young women in the National Longitudinal Study of Adolescent to Adult Health, this study describes father-daughter relationships, examines the association between father daughter relationships and daughters' early sexual initiation, and considers the impact of migration on the father-daughter relationship and sexual health among Mexican-origin young women. RESULTS: Qualitative data identify four types of father-daughter relationships: 'good,' hostile, distant, and conflicted. Supporting the qualitative patterns, quantitative data find that positive or 'good' father-daughter relationship quality is significantly associated with reduced risk of early sexual initiation. Importantly, father-daughter separation across borders and economic inequality facing immigrant families is associated with hostile or distant father-daughter relationship quality and increased risk of early sexual initiation. CONCLUSIONS: Reports of good father-daughter relationships are common and may protect against early sexual initiation in Mexican-origin immigrant families. Policies that keep families together and reduce economic inequality among immigrants may also reduce sexual health disparities among immigrant adolescents.

AB - BACKGROUND: Little data exist on the use of direct oral anticoagulant (DOAC) factor Xa inhibitors for submassive pulmonary embolism (PE) after catheter directed thrombolysis (CDT). The objective of this evaluation was to determine whether the transition from parenteral anticoagulation to DOACs for submassive PE after CDT would decrease hospital length of stay (LOS) compared to warfarin. METHODS: A retrospective review of patients diagnosed with submassive PE who underwent CDT was conducted from January 1, 2012, to February 28, 2017. Hospital LOS and major and minor bleeding events were recorded during hospitalization and at 90 days. RESULTS: Sixty-two patients met the inclusion criteria, 36 in warfarin group and 26 in the DOAC group. Overall, patients receiving rivaroxaban or apixaban had a shorter median hospital LOS compared to warfarin (4.0 vs 6.1 days, P = .002). In the multivariate regression analysis, administration of DOAC was an independent predictor of decreased hospital LOS, beta: -2.1, 95% confidence interval (-3.5 to -0.7). CONCLUSION: Among patients with submassive PE, initiation of a DOAC shortly after CDT may result in a decreased hospital LOS compared to parenterally bridged warfarin. PMID- 29455568 TI - Effectiveness and Safety of LMWH Treatment in Patients With Cancer Diagnosed With Non-High-Risk Venous Thromboembolism: Turkish Observational Study (TREBECA). AB - We compared the efficacy and safety of low-molecular-weight heparins (LMWHs) in patients with cancer who are at low risk of venous thromboembolism (VTE). Patients were treated by medical oncologists in Turkey at 15 sites, where they were enrolled and followed up for a period of 12 months. Due to the study design, there was no specific treatment protocol for LMWH. Primary end points were efficacy and the time to change in VTE status. Of the included 250 patients, 239 (95.6%), 176 (70.4%), 130 (52.0%), and 91 (36.4%) completed their day 15, month 3, month 6, and month 12 visits, respectively. Number of patients treated with enoxaparin, bemiparin, and tinzaparin were 133, 112, and 5, respectively. Anticoagulant therapy provoked thrombus resolution in 1.2% and 12.7% of patients using enoxaparin and bemiparin, respectively ( P = .004). Thrombus resolution was observed in 81 more patients at month 3 visit. This ratio was 35 (40.2%) of 87 and 46 (54.1%) of 85 patients administered enoxaparin and bemiparin at the third visit, respectively ( P = .038). Thrombus resolution was observed in 21 more patients during month 6 visit. This ratio was 5 (7.7%) of 65 and 15 (23.4%) of 64 patients administered enoxaparin and bemiparin at the fourth visit, respectively ( P = .022). The LMWH was discontinued in only 2 patients due to gastrointestinal bleeding. This pioneering study shows bemiparin is more effective than enoxaparin in thrombosis resolution and has a similar tolerability profile.

Because skins of many dangerous animals are typically repetitive, we propose that repetition is the key feature enabling recognition of evolutionarily important threats. The current study consists of two experiments where we measured participants' reactions to pictures of male and female models wearing clothing of various repeating (leopard skin, snakeskin, and floral print) and nonrepeating (camouflage, shiny, and plain) patterns. In Experiment 1, when models wearing patterns were presented side by side with total fixation duration as the measure, the repeating floral pattern was the most provocative, with total fixation duration significantly longer than all other patterns. Leopard and snakeskin patterns had total fixation durations that were significantly longer than the plain pattern. In Experiment 2, we employed a visual-search task where participants were required to find models wearing the various patterns in a setting of a crowded airport terminal. Participants detected leopard skin pattern and repetitive floral pattern significantly faster than two of the nonpatterned clothing styles. Our experimental findings support the hypothesis that repetition of specific visual features might facilitate target detection, especially those characterizing evolutionary important threats. Our findings that intricate, but nonthreatening repeating patterns can have similar attention-grabbing properties to animal skin patterns have important implications for the fashion industry and wildlife trade. PMID- 29455570 TI - Unmet digital health service needs in dermatology patients. AB - BACKGROUND: Digital health services are rapidly gaining acceptance in healthcare systems. Dermatology as an image-centric specialty is particularly well suited for telemedical services. However, dermatology patients' demands of electronic services remain largely unexplored. METHODS: This study investigated patients' views in primary, secondary, and tertiary referral centers. In August 2017, 841 questionnaires were filled in by dermatology patients. RESULTS: 76.34% expressed interest in using digital healthcare services as part of medical consultations. 84.41% of all patients would complete their initial registration form electronically. Fewer patients were comfortable with sending pictures of skin changes to their doctors using email (40.89%) or mobile health applications (40.61%). Specific interest was indicated for arranging appointments online (90.80%) and electronically-placed prescriptions (76.56%), rather than online learning videos (42.03%), and actual online consultations (34.53%). 65.37% of patients would pay for online consultations themselves. CONCLUSIONS: Taken together, interest in electronic health services is high in dermatology patients. Our data suggest that readily understandable electronic services such as online arranged appointments and electronic prescriptions are of higher interest to patients than the current type of online consultations. Therefore, the full potential of teledermatology still remains to be tapped by newer, more attractive forms of services closely adapted to patients' demands. PMID- 29455571 TI - Genetic Variation of the Kinases That Phosphorylate Tenofovir and Emtricitabine in Peripheral Blood Mononuclear Cells. AB - Tenofovir (TFV) disoproxil fumarate and emtricitabine (FTC) are used in combination for HIV treatment and pre-exposure prophylaxis (PrEP). TFV disoproxil fumarate is a prodrug that undergoes diester hydrolysis to TFV. FTC and TFV are nucleoside/nucleotide reverse transcriptase inhibitors that upon phosphorylation to nucleotide triphosphate analogs competitively inhibit HIV reverse transcriptase. We previously demonstrated that adenylate kinase 2, pyruvate kinase, muscle and pyruvate kinase, liver and red blood cell phosphorylate TFV in peripheral blood mononuclear cells (PBMC). To identify the kinases that phosphorylate FTC in PBMC, siRNAs targeted toward kinases that phosphorylate compounds structurally similar to FTC were delivered to PBMC, followed by incubation with FTC and the application of a matrix-assisted laser desorption ionization-mass spectrometry method and ultra high performance liquid chromatography-UV to detect the formation of FTC phosphates. Knockdown of deoxycytidine kinase decreased the formation of FTC-monophosphate, while siRNA targeted toward thymidine kinase 1 decreased the abundance of FTC-diphosphate. Knockdown of either cytidine monophosphate kinase 1 or phosphoglycerate kinase 1 decreased the abundance of FTC-triphosphate. Next-generation sequencing of genomic DNA isolated from 498 HIV-uninfected participants in the HIV Prevention Trials Network 069/AIDS Clinical Trials Group A5305 clinical study, revealed 17 previously unreported genetic variants of TFV or FTC phosphorylating kinases. Of note, four individuals were identified as simultaneous carriers of variants of both TFV and FTC activating kinases. These results identify the specific kinases that activate FTC in PBMC, while also providing further insight into the potential for genetic variation to impact TFV and FTC activation.

AB - For HIV-1 serodiscordant couples, HIV-1 exposure and risk of transmission is heightened during pregnancy attempts, but safer conception strategies can reduce risk. As safer conception programs are scaled up, understanding couples' preferences and experiences can be useful for programmatic recommendations. We followed 1013 high-risk, heterosexual HIV-1 serodiscordant couples from Kenya and Uganda for two years in an open-label delivery study of integrated pre-exposure prophylaxis (PrEP) and antiretroviral therapy (ART), the Partners Demonstration Project. We used descriptive statistics to describe the cohort and multivariate logistic regression to characterize women who reported use of a safer conception strategy by their first annual visit. 66% (569/859) of women in the study were HIV-infected and 73% (627/859) desired children in the future. At the first annual visit, 59% of women recognized PrEP, 58% ART, 50% timed condomless sex, 23% self-insemination, and fewer than 10% recognized male circumcision, STI treatment, artificial insemination, and sperm washing as safer conception strategies. Among those recognizing these strategies and desiring pregnancy, 37% reported using PrEP, 14% ART, and 30% timed condomless sex. Women who reported discussing their fertility desires with their male partners were more likely to report having used at least one strategy for safer conception (adjusted odds ratio = 1.91, 95% confidence interval:1.26-2.89). Recognition of use of safer conception strategies among women who expressed fertility desires was low, with ARV-based strategies and self-insemination the more commonly recognized and used strategies. Programs supporting HIV-1 serodiscordant couples can provide opportunities for couples to talk about their fertility desires and foster communication around safer conception practices. PMID- 29455573 TI - A CREB-mediated increase in miRNA let-7f during prolonged beta-agonist exposure: a novel mechanism of beta2-adrenergic receptor down-regulation in airway smooth muscle. AB - beta2-Adrenergic receptors (beta2ARs) desensitize during continuous agonist activation, which manifests clinically as tachyphylaxis. beta-Agonist desensitization of beta2ARs in human airway smooth muscle (HASM) cells is recognized in the treatment of asthma and may be related to poor outcomes. Rapid events in desensitization include receptor phosphorylation and internalization, but mechanisms responsible for the decrease in receptor protein after prolonged agonist exposure (down-regulation) are ill defined. The microRNA (miRNA) let-7f regulates beta2AR expression by translational repression. In cultured HASM cells from nonasthmatic and asthmatic lungs, 18 h of beta-agonist exposure increased let-7f by 2-3-fold, concomitant with a ~90% decrease in beta2ARs. Inhibition of let-7f attenuated this down-regulation response by ~50%. The let-7f increase was found to be cAMP/PKA-dependent. The mechanism of the let-7f increase was found by chromatin immunoprecipitation to be from activated cAMP response element-binding protein (CREB) binding to the let-7f promoter, thereby increasing let-7f expression. Knockdown of CREB attenuated agonist-promoted beta2AR down-regulation by ~50%. Thus, beta2AR down-regulation occurs as a result of not only internalized receptor degradation but also a novel cAMP/PKA/CREB-mediated increase in let-7f, which causes enhanced repression of the beta2AR gene, adrenoreceptor beta2 ( ADRB2) translation and represents ~50% of the net loss of receptors observed after prolonged agonist exposure. This mechanism is apparent in asthmatic HASM cells, indicating relevance in a disease model.-Kim, D., Cho, S., Woo, J. A., Liggett, S. B. A CREB-mediated increase in miRNA let-7f during prolonged beta-agonist exposure: a novel mechanism of beta2-adrenergic receptor down-regulation in airway smooth muscle. PMID- 29455575 TI - Exercise counteracts the homeostatic decrease in thermogenesis caused by caloric restriction in sheep. AB - Caloric restriction causes a homeostatic reduction in thermogenesis. We aimed to determine whether exercise could counteract this. We studied four groups of normal-weight ewes ( n = 5), including control sedentary fed ad libitum, exercise fed ad libitum (30 min/d, 5 d/wk), diet-restricted (70% of ad libitum food intake), and combined diet and exercise. Temperature probes implanted in sternal and retroperitoneal adipose tissue and skeletal muscle measured thermogenesis. After the 4-wk intervention, hypothalami were collected for in situ hybridization, and fat and muscle biopsies were collected for real-time PCR and Western blotting. Combined diet and exercise reduced adiposity ( P < 0.05). Caloric restriction alone reduced overnight temperatures in sternal and retroperitoneal fat ( P < 0.05), which was counteracted by exercise ( P < 0.05). Exercise did not induce expression of cellular markers of browning in adipose tissue. There was no effect of diet or exercise on skeletal muscle thermogenesis. Combined diet and exercise increased the expression of neuropeptide Y and agouti related protein in the hypothalamic arcuate nucleus ( P < 0.05), consistent with reduced adiposity. Gene expressions of key hypothalamic appetite-regulating peptides were not associated with altered thermogenesis. We demonstrate that exercise counteracts the inhibitory effect of caloric restriction to restore thermogenesis in adipose tissue of sheep.-Fuller-Jackson, J.-P., Clarke, I. J., Rao, A., Henry, B. A. Exercise counteracts the homeostatic decrease in thermogenesis caused by caloric restriction in sheep. PMID- 29455574 TI - Immune responsive resolvin D1 programs myocardial infarction-induced cardiorenal syndrome in heart failure. AB - Resolvins are innate, immune responsive, bioactive mediators generated after myocardial infarction (MI) to resolve inflammation. The MI-induced bidirectional interaction between progressive left ventricle (LV) remodeling and kidney dysfunction is known to advance cardiorenal syndrome (CRS). Whether resolvins limit MI-induced cardiorenal inflammation is unclear. Thus, to define the role of exogenous resolvin D (RvD)-1 in post-MI CRS, we subjected 8- to 12-wk-old male C57BL/6 mice to coronary artery ligation. RvD1 was injected 3 h after MI. MI mice with no treatment served as MI controls (d 1 and 5). Mice with no surgery served as naive controls. In the injected mice, RvD1 promoted neutrophil (CD11b+/Ly6G+) egress from the infarcted LV, compared with the MI control group at d 5, indicative of neutrophil clearance and thereby resolved inflammation. Further, RvD1-injected mice showed higher reparative macrophages (F4/80+/Ly6Clow/CD206+) in the infarcted LV than did MI control mice at d 5 after MI. RvD1 suppressed the miRNA storm at d 1 and limited the MI-induced edematous milieu in a remote area of the LV compared with the MI control at d 5 after MI. Also, RvD1 preserved the nephrin expression that was diffuse in the glomerular membrane at d 5 and 28 in MI controls, indicating renal injury. RvD1 attenuated MI-induced renal inflammation, decreasing neutrophil gelatinase-associated lipocalin and proinflammatory cytokines and chemokines in the kidney compared with the MI control. In summary, RvD1 clears MI-induced inflammation by increasing resolving leukocytes and facilitates renoprotective mechanisms to limit CRS in acute and chronic heart failure.-Halade, G.

PMID- 29455576 TI - Central Infusion of Insulin-Like Growth Factor-1 Increases Hippocampal Neurogenesis and Improves Neurobehavioral Function after Traumatic Brain Injury. AB - Traumatic brain injury (TBI) produces neuronal dysfunction and cellular loss that can culminate in lasting impairments in cognitive and motor abilities. Therapeutic agents that promote repair and replenish neurons post-TBI hold promise in improving recovery of function. Insulin-like growth factor-1 (IGF-1) is a neurotrophic factor capable of mediating neuroprotective and neuroplasticity mechanisms. Targeted overexpression of IGF-1 enhances the generation of hippocampal newborn neurons in brain-injured mice; however, the translational neurogenic potential of exogenously administered IGF-1 post-TBI remains unknown. In a mouse model of controlled cortical impact, continuous intracerebroventricular infusion of recombinant human IGF-1 (hIGF) for 7 days, beginning 15 min post-injury, resulted in a dose-dependent increase in the number of immature neurons in the hippocampus. Infusion of 10 MUg/day of IGF-1 produced detectable levels of hIGF-1 in the cortex and hippocampus and a concomitant increase in protein kinase B activation in the hippocampus. Both motor function and cognition were improved over 7 days post-injury in IGF-1-treated cohorts. Vehicle-treated brain-injured mice showed reduced hippocampal immature neuron density relative to sham controls at 7 days post-injury. In contrast, the density of hippocampal immature neurons in brain-injured mice receiving acute onset IGF-1 infusion was significantly higher than in injured mice receiving vehicle and equivalent to that in sham-injured control mice. Importantly, the neurogenic effect of IGF-1 was maintained with as much as a 6-h delay in the initiation of infusion. These data suggest that central infusion of IGF-1 enhances the generation of immature neurons in the hippocampus, with a therapeutic window of at least 6 h post-injury, and promotes neurobehavioral recovery post-TBI. PMID- 29455579 TI - VMAT2 Inhibitors for Tardive Dyskinesia-Practice Implications. AB - Tardive dyskinesia is a potentially irreversible, debilitating, hyperkinetic movement disorder that can result from dopamine receptor antagonists. Prompt recognition and resolution of symptoms are instrumental in preventing disease irreversibility, though current treatment options have fallen short of robust, effective, and long-term symptom control. In April 2017, the Food and Drug Administration (FDA) approved 2 new vesicular monoamine transporter 2 (VMAT2) inhibitors, deutetrabenazine and valbenazine, for chorea related to Huntington's disease and tardive dyskinesia, respectively. These agents were pharmacologically modified from tetrabenazine, a VMAT2 inhibitor used off-label in the treatment of tardive dyskinesia. Despite FDA-labeled indications of deutetrabenazine and valbenazine, each agent was explored as a treatment option for those with tardive dyskinesia. In this study, the pharmacologic modifications of the 2 new VMAT2 inhibitors are described, with detailed explanation as to how these may impact clinical practice. The associated case series, observational studies, and clinical trials exploring their use in the treatment of tardive dyskinesia are reported with expert opinion on practice implication. PMID- 29455577 TI - Exploring autophagy with Gene Ontology. AB - Autophagy is a fundamental cellular process that is well conserved among eukaryotes. It is one of the strategies that cells use to catabolize substances in a controlled way. Autophagy is used for recycling cellular components, responding to cellular stresses and ridding cells of foreign material. Perturbations in autophagy have been implicated in a number of pathological conditions such as neurodegeneration, cardiac disease and cancer. The growing knowledge about autophagic mechanisms needs to be collected in a computable and shareable format to allow its use in data representation and interpretation. The Gene Ontology (GO) is a freely available resource that describes how and where gene products function in biological systems. It consists of 3 interrelated structured vocabularies that outline what gene products do at the biochemical level, where they act in a cell and the overall biological objectives to which their actions contribute. It also consists of 'annotations' that associate gene products with the terms. Here we describe how we represent autophagy in GO, how we create and define terms relevant to autophagy researchers and how we interrelate those terms to generate a coherent view of the process, therefore allowing an interoperable description of its biological aspects. We also describe how annotation of gene products with GO terms improves data analysis and interpretation, hence bringing a significant benefit to this field of study. PMID- 29455580 TI - From Family Involvement to Family Inclusion in Nursing Home Settings: A Critical Interpretive Synthesis. AB - The provision of care work by families plays an integral role in the quality of life of older adults living in a nursing home setting. This critical interpretive synthesis examines family members' perceptions of their roles and responsibilities in nursing home settings and interrogates the structural and relational barriers and enablers to family involvement as they relate to fostering an inclusive environment. Electronic databases and published literature were searched for empirical studies that were conducted in a nursing home setting and described involvement from the perspective of family members. Thirty-two articles published between 2006 and 2016 were included in the review. Although involvement comprised a variety of roles and responsibilities, it was grounded in family-resident relationships, influenced by family-staff relationships, and deeply affected by broader sociopolitical factors. We conclude that involvement should be understood as a democratic process with supporting policies and programs to encourage family inclusion in facility life. PMID- 29455581 TI - Keeping it tight: The relationship between bacterial dysbiosis, septate junctions, and the intestinal barrier in Drosophila. AB - Maladaptive changes in the intestinal flora, typically referred to as bacterial dysbiosis, have been linked to intestinal aging phenotypes, including an increase in intestinal stem cell (ISC) proliferation, activation of inflammatory pathways, and increased intestinal permeability1,2. However, the causal relationships between these phenotypes are only beginning to be unravelled. We recently characterized the age-related changes that occur to septate junctions (SJ) between adjacent, absorptive enterocytes (EC) in the fly intestine. Changes could be observed in the overall level of SJ proteins, as well as the localization of a subset of SJ proteins. Such age-related changes were particularly noticeable at tricellular junctions (TCJ)3. Acute loss of the Drosophila TCJ protein Gliotactin (Gli) in ECs led to rapid activation of stress signalling in stem cells and an increase in ISC proliferation, even under axenic conditions; a gradual disruption of the intestinal barrier was also observed. The uncoupling of changes in bacteria from alterations in ISC behaviour and loss of barrier integrity has allowed us to begin to explore the interrelationship of these intestinal aging phenotypes in more detail and has shed light on the importance of the proteins that contribute to maintenance of the intestinal barrier.

AB - OBJECTIVE: The objective of this study is to examine the frequency of abnormal Chromosomal Microarray (CMA) analyses among fetuses with isolated non visualization of fetal gallbladder. METHODS: Data from CMA analyses performed due to isolated non-visualization of fetal gallbladder between January 2013 and September 2016 were retrospectively acquired from a computerized database of the Israeli Ministry of Health. The results were compared with the rate for clinically significant CMA findings in general population, based on a large cohort of 5541 pregnancies undergoing CMA due to maternal request, and a systematic review of 9272 cases with normal ultrasound. RESULTS: Of 45 pregnancies with isolated non-visualization of fetal gallbladder, CMA testing yielded one (2.22%) gain-of-copy-number variant at 16p11.2, categorized as "pathogenic". In addition, one finding of unknown significance was demonstrated. The risk for clinically meaningful CMA findings among pregnancies with isolated absent gallbladder was not significantly increased compared to control population. CONCLUSIONS: To the best of our knowledge, this study is the first report describing the rate of pathogenic CMA results in fetuses with isolated non visualization of fetal gallbladder. The results, in conjunction with previous studies, show that the risk for abnormal CMA results in pregnancies diagnosed with non-visualized gallbladder is not significantly different from pregnancies with normal ultrasound.

PMID- 29455584 TI - HEPES activates a MiT/TFE-dependent lysosomal-autophagic gene network in cultured cells: A call for caution. AB - In recent years, the lysosome has emerged as a highly dynamic, transcriptionally regulated organelle that is integral to nutrient-sensing and metabolic rewiring. This is coordinated by a lysosome-to-nucleus signaling nexus in which MTORC1 controls the subcellular distribution of the microphthalmia-transcription factor E (MiT/TFE) family of "master lysosomal regulators". Yet, despite the importance of the lysosome in cellular metabolism, the impact of traditional in vitro culture media on lysosomal dynamics and/or MiT/TFE localization has not been fully appreciated. Here, we identify HEPES, a chemical buffering agent that is broadly applied in cell culture, as a potent inducer of lysosome biogenesis. Supplementation of HEPES to cell growth media is sufficient to decouple the MiT/TFE family members-TFEB, TFE3 and MITF-from regulatory mechanisms that control their cytosolic retention. Increased MiT/TFE nuclear import in turn drives the expression of a global network of lysosomal-autophagic and innate host immune response genes, altering lysosomal dynamics, proteolytic capacity, autophagic flux, and inflammatory signaling. In addition, siRNA-mediated MiT/TFE knockdown effectively blunted HEPES-induced lysosome biogenesis and gene expression profiles. Mechanistically, we show that MiT/TFE activation in response to HEPES requires its macropinocytic ingestion and aberrant lysosomal storage/pH, but is independent of MTORC1 signaling. Altogether, our data underscore the cautionary use of chemical buffering agents in cell culture media due to their potentially confounding effects on experimental results.

PMID- 29455593 TI - Acute compressive stress activates RHO/ROCK-mediated cellular processes. AB - The ability to rapidly respond to applied force underpins cell/tissue homeostasis. This response is mediated by mechanotransduction pathways that regulate remodeling and tension of the actomyosin cytoskeleton to counterbalance external forces. Enhanced extracellular matrix tension hyper-activates mechanotransduction and characterizes diseased states such as cancer, but is also required for normal epidermal regeneration. While the impact of extracellular matrix tension on signaling and cell biology are well appreciated, that of acute compressive force is under-studied. We show here that acute compressive force applied to cells and tissues in a native 3-dimensional context elevates RHOA-GTP levels and increases regulatory myosin phosphorylation, actomyosin contractility and tension via ROCK. In consequence, cell proliferation was increased, as was the expression of regulators of epithelial-mesenchymal transition. Pharmacological inhibition of ROCK abrogated myosin phosphorylation, but not RHOA activation. Our results strongly suggest that acute compressive stress impairs cellular homeostasis in a RHO/ROCK-dependent manner, with implications for disease states such as cancer. PMID- 29455594 TI - Vaginal birth after a cesarean delivery for arrest of descent. AB - OBJECTIVE: The objective of this study is to determine vaginal birth after cesarean (VBAC) success rates for patients with a prior cesarean delivery (CD) for arrest of descent, as well as determine any predictors for success. STUDY DESIGN: This was a retrospective cohort study of all patients delivered by a single MFM practice from 2005 to 2017 with a singleton pregnancy and one prior CD for arrest of descent. We estimated the rate and associated risk factors for successful VBAC. RESULTS: We included 208 patients with one prior CD for arrest of descent, 100 (48.1%) of whom attempted a trial of labor after cesarean (TOLAC) with a VBAC success rate was 84/100 (84%, 95% CI 76-90%). Among the women who attempted TOLAC, women with a prior vaginal delivery >24 weeks' had a significantly higher VBAC success rate (91.8% versus 71.8%, p = .01). Maternal age, body mass index, estimated fetal weight, induction of labor, and cervical dilation were not associated with a higher VBAC success rate. CONCLUSIONS: For women with a prior CD for arrest of descent, VBAC success rates are high. This suggests that arrest of descent is mostly dependent on factors unique to each pregnancy and not due to an inadequate pelvis or recurring conditions. Women with a prior CD for arrest of descent should not be discouraged from attempting TOLAC in a subsequent pregnancy due to concerns about the likelihood of success.

AB - BACKGROUND: Skype technology was implemented by the Australian Maternal Early Childhood Sustained Home-visiting (MECSH) Support Service as a tool for the remote provision of clinical supervision for clinicians working in the MECSH program in Seoul, South Korea. OBJECTIVES: To gain a better understanding of the processes underpinning sustainable delivery of remote clinical supervision using digital technologies. DESIGN: A phenomenographical study. METHODS: Recorded notes and reflections on each supervision session, noting exemplars and characteristics of the experience were read and re-read to derive the characterizations of the experience. RESULTS: The experience has provided learnings in three domains: (1) the processes in using Skype; (2) supervisory processes; and (3) language translation, including managing clarity of, and time for translation. CONCLUSION: Skype has potential for use in remote provision of clinical supervision, including where translation is required. Further research evaluating the benefit of telesupervision from supervisor and supervisee perspectives is necessary to determine if it is a sustainable process. PMID- 29455611 TI - Evaluation of foetal neurological behaviour in hypothyroid pregnant females - a pilot study. AB - OBJECTIVES: Maternal hypothyroidism is known for its possible deleterious effect on the neurocognitive function of the offspring. The aim of the current study is to investigate if maternal hypothyroidism also affects foetal neurological behaviour. METHODS: Fifty foetuses were examined for abnormal neurological behaviour from 25 euthyroid and 25 hypothyroid age matched pregnant females, between 28 and 38 weeks gestation. The hypothyroid group was further subdivided into controlled (n = 5) and uncontrolled (n = 20) groups. Evaluation of foetal neurological behaviour using Kurjak's antenatal neurodevelopmental test (KANET) test was performed. RESULTS: Mean total KANET score was significantly lower for foetuses in the hypothyroid group compared to the euthyroid (p < .001, 95% CI: 2 6). The number of foetuses showing pathological scores was significantly higher in the hypothyroid group (9, 36%) compared to euthyroid (1, 4%) (p < .005). The distribution of total KANET score was significantly different between the two groups (p = .017). Foetuses in the uncontrolled hypothyroid group showed lower mean KANET scores (9.650 +/- 2.907 versus 10.80 +/- 3.03) and higher frequency of pathological scores compared to controlled (8 = 40% versus 1 = 20%) although without statistical significance. The distribution of total KANET score was not statistically significant between the two groups (p = .893). CONCLUSIONS: Overt maternal hypothyroidism may adversely affect foetal neurological behaviour. Correlation of prenatal findings with postnatal long-term neurological development is recommended in such cases. PMID- 29455612 TI - Are levels of coping with stress in pregnancy with gestational diabetes worse than in healthy pregnancy? AB - PURPOSE: The purpose of this study was to analyze the levels of coping with stress in healthy pregnant women in comparison with the levels of coping with stress in pregnant women with gestational diabetes mellitus (GDM). MATERIALS AND METHODS: In the study, the descriptive cross-sectional research design was used. The study was carried out with 218 pregnant women in total. RESULTS: It was found that the healthy pregnant women had a higher total score for coping with stress and used the self-confident coping style, one of the effective coping styles, more frequently when compared to the pregnant women with GDM (p < .001). In addition, the pregnant women with GDM used the desperate coping style, one of the ineffective coping styles, more frequently than the healthy pregnant women (p < .001). CONCLUSIONS: Diabetes education that nurses give should allow not only the nurses to evaluate the coping levels of pregnant women with GDM, but also to teach these pregnant women how to use effective coping styles. PMID- 29455613 TI - Liposuction-assisted circumferential trimming in treatment of axillary osmidrosis (AO). AB - BACKGROUND: The study is to investigate the effectiveness and safety of the minimally invasive treatment for axillary osmidrosis by liposuction assisted circumferential trimming. METHODS: It was a retrospective study. From July 2014 to July 2017, 79 patients underwent superficial liposuction and circumferential trimming for bilateral axillary osmidrosis. The preoperative and postoperative degree of axillary malodor was measured by doctors and the patients themselves. In the doctor's evaluation, the odor levels were scored by the sniffing method before and 1 year after treatment. In the patient's self-assessment, each patient selected a scale value to convey his/her satisfaction during the visits after 1 year. The complications were recorded. RESULTS: The follow-up period ranged from 12 to 24 months after surgery, and the mean follow-up period was 16 months. 75 (94.9%) had good results, four (5.1%) had moderate malodor or recurrence after one year. When considering patient's own satisfaction, 93.7% (74/79) of patients were satisfied with the outcomes after one year. The partial epidermis necrosis was observed in four patients, it healed spontaneously without scarring. Three patients had a small amount of hematoma which was easily evacuated through the central primary incision. There was no other serious side effect. CONCLUSIONS: The liposuction assisted circumferential trimming technique is proved reliable and safe in treatment for axillary osmidrosis. PMID- 29455614 TI - DDR1: A major player in renal diseases. AB - Discoidin Domain Receptor 1 (DDR1) belongs to a family of two non-integrin collagen receptors, DDR1 and DDR2, which display a tyrosine kinase activity. DDR1 has been widely studied in different kind of pathologies including chronic kidney diseases (CKD). The aims of this commentary are 1. to review the existing information about DDR1 expression in healthy and diseased kidney, 2. to comment the data highlighting DDR1 as a major actor in CKD, 3. to suggest areas of research which require further investigation to better characterize the signaling pathways regulating DDR1 role in CKD. The results recapitulated in this commentary emphasize the involvement of DDR1 in the pro-inflammatory and pro fibrotic processes which drives the development of CKD. They also underline the beneficial effect of its blockade in pre-clinical models and thus, reinforce its status of interesting therapeutic target.

We included all nonanomalous singleton pregnancies that had an ultrasound scan performed between 36 and 38 weeks gestation. Excluded was any major congenital abnormality, aneuploidy, multiple pregnancy, preterm birth, maternal hypertension, or diabetes. The primary outcome was a severe composite neonatal outcome (SCNO) defined as severe acidosis (umbilical cord artery pH <7.0, cord lactate >=6 mmol/L, cord base excess <=-12 mmol/L) Apgar score <=3 at 5 minutes, admission to the neonatal intensive care unit (NICU), and death. A low CPR was defined as <10th centile for gestation and small for gestational age (SGA) was defined as an EFW <10th centile and appropriate for gestational age (AGA) was defined as EFW >=10th centile. RESULTS: Of 2425 pregnancies, 13.2% (321/2425) had a fetus with a CPR <10th centile and 13.7% (332/2425) with an EFW <10th centile. Both a low CPR and SGA predicted the SCNO. Individually a low CPR and SGA had sensitivity for detection of SCNO of 23.3% and 24.7%, respectively which increased to 36.7% when combined. Both were associated with emergency caesarean for nonreassuring fetal status (NRFS), as well as early-term birth and admission to NICU. Stratifying the population into EFW <10th centile and EFW >=10th centile, a low CPR maintained its association with the SCNO, early-term birth and emergency caesarean for NRFS in the cohort with an EFW <10th centile but SCNO lost its association with a low CPR in the EFW >10th cohort. Stratifying the population into CPR <10th centile and CPR >10th centile, a low EFW was associated with early-term birth, induction of labor, admission to NICU, and the SCNO. CONCLUSIONS: In a low-risk cohort both the CPR and EFW individually and in combination predicts adverse obstetric and perinatal outcomes when measured late in pregnancy. However, the predictive value was enhanced when both were used in combination. PMID- 29455617 TI - The role of premorbid adjustment in schizophrenia: Focus on cognitive remediation outcome. AB - Premorbid adjustment has been associated with several outcomes in schizophrenia and has been proposed as an index of cognitive reserve. This study aims to comprehensively analyse the relation between premorbid adjustment and clinical, neurocognitive, socio-cognitive and functional assessments, as well as to investigate the effect of premorbid adjustment on cognitive improvements after a cognitive remediation therapy protocol. Seventy-nine clinically stabilised outpatients with schizophrenia underwent a combined intervention consisting of cognitive remediation therapy added to standard rehabilitation therapy. All patients were assessed at baseline for psychopathology, premorbid adjustment, intellectual level, cognition and functioning. Cognitive evaluations were also repeated after the intervention. At baseline, significant correlations were observed between premorbid adjustment and working memory. The global cognitive improvement after treatment was significantly predicted by age and premorbid adjustment. This study confirms the association between premorbid adjustment and cognitive impairment and is the first to highlight the possible role of premorbid adjustment on the capacity to recover from cognitive deficits through a cognitive remediation therapy protocol. The data suggest that cognitive remediation may be particularly effective for people in the early course and that the assessment of premorbid adjustment could be of value to design individualised interventions. PMID- 29455618 TI - Maternal protein S activity is associated with massive hemorrhage during caesarean section: retrospective case-control study. AB - OBJECTIVE: The objective of this study is to identify any correlation between the maternal protein S (PS) activity, which decreases spontaneously during normal pregnancy, and the pregnancy outcome, especially the amount of bleeding during caesarean section (CS). MATERIALS AND METHODS: We analyzed 129 pregnant women who received elective CS at our hospital which is a tertiary perinatal center. The relationship between the amount of intraoperative hemorrhage and PS activity was estimated by simple linear regression. Univariate and multivariate analyses were also performed to determine whether or not the maternal PS activity was associated with massive hemorrhage (>1000 g). RESULTS: The maternal PS activity correlated with the amount of intraoperative hemorrhage (p = .048, r = 0.175) and could be an independent predictor of massive hemorrhage (odds ratio 1.06; 95% confidence interval 1.01-1.12; p = .013). CONCLUSIONS: Maternal PS activity was associated with the amount of hemorrhage during CS and the occurrence of massive hemorrhage. PS activity reduction naturally occurring during pregnancy could contribute to alleviation of massive hemorrhage.

AB - Development of multicellular organisms is a highly orchestrated process, with cells responding to factors and features present in the extracellular milieu. Changes in the surrounding environment help decide the fate of cells at various stages of development. This review highlights recent research that details the effects of mechanical properties of the surrounding environment and extracellular matrix and the underlying molecular mechanisms that regulate the behavior of embryonic stem cells (ESCs). In this study, we review the role of mechanical properties during embryogenesis and discuss the effect of engineered microtopographies on ESC pluripotency. PMID- 29455620 TI - Bacterial-mediated biodegradation of pentachlorophenol via electron shuttling. AB - Pentachlorophenol (PCP) degradation by soil indigenous bacteria represents a practical and cost-effective solution. In the present study, bacteria isolated from paddy soil was investigated and the role of electron shuttling (ES) in the PCP degradation process was assessed. Two strains demonstrated the highest PCP degradation of 93.5% and 94.88% in the presence of citrate and were identified using 16S rRNA phylogenetic analysis as Pseudomonas chengduensis and Pseudomonas plecoglossicida, respectively. Both strains showed higher PCP degradation in free form as opposed to a reduced activity in immobilized and respiratory impaired form. The addition of pyruvate resulted in about 80% PCP degradation in 5 days for P. chengduensis, on the other hand, P. plecoglossicida showed the same result under anaerobic conditions whether pyruvate was added or not. Phenazine and the outer membrane c-type cytochrome were reported only for P. chengduensis as opposed to P. plecoglossicida. The results indicate that despite following different approaches in PCP degradation, both strains are useful in PCP clean-up under aerobic and anaerobic conditions and in free direct contact. The degradation is enhanced via ES. This is considered both an effective and feasible technology for in situ clean-up of contaminated sites or on-site bioreactors. PMID- 29455621 TI - Optimization of Endometrial Decidualization in the Menstruating Mouse Model for Preclinical Endometriosis Research. AB - BACKGROUND: To induce endometrial decidualization in rodents, an intrauterine oil stimulus can be delivered via the nontraumatic vagina or via the traumatic laparotomy. However, there is considerable variation in amount of decidualization using these inducing methods. Therefore, we studied which oil delivery route could achieve the highest rate of endometrial decidualization along the full length of both uterine horns. METHODS: To induce decidualization, ovariectomized C57Bl/6J mice were injected with estrogen (100 ng/day; 3 days). A progesterone pellet (5 mg) was implanted subcutaneously, followed by estrogen injections (5 ng/day; 3 days). Oil (20 uL/horn) was injected in the uterus via laparotomy, laparoscopy, or vagina. Four days later, the pellet was removed, followed by hysterectomy after 4 to 6 hours. Endometrial decidualization was evaluated macroscopically and microscopically using hematoxylin and eosin and desmin staining. Furthermore, uterine weight and hormone levels were measured. RESULTS: The proportion of animals with macroscopic bicornuate decidualization was higher after laparoscopic (83%) and laparotomic (89%) injection than after sham injection (11%). Furthermore, macroscopic bicornuate decidualization was significantly higher after laparotomic injection (89%) compared to the vaginal injection (38%). Uterine weight and endometrial surface area were significantly higher in both laparotomy and laparoscopy groups compared to the sham group, while the relative desmin-positive endometrial surface area was only significantly different between the laparotomy and the sham animals. CONCLUSION: Methods using laparoscopic and laparotomic intrauterine oil injection resulted in a higher amount of decidualized endometrium compared to sham injection, although further optimization is needed to reach full bicornuate decidualization. PMID- 29455622 TI - Synthesis of low cost organometallic-type catalysts for their application in microbial fuel cell technology. AB - Microbial fuel cells (MFCs) are a promising technology that generates electricity from several biodegradable substrates and wastes. The main drawback of these devices is the need of using a catalyst for the oxygen reduction reaction at the cathode, which makes the process relatively expensive. In this work, two low cost materials are tested as catalysts in MFCs. A novel iron complex based on the ligand n-phenyledenparaethoxy aniline has been synthesized and its performance as catalyst in single chamber MFCs containing ionic liquids has been compared with a commercial inorganic material such as Raney nickel. The results show that both materials are suitable for bioenergy production and wastewater treatment in the systems. Raney nickel cathodes allow MFCs to reach a maximum power output of 160 mW.m-3anode, while the iron complex offers lower values. Regarding the wastewater treatment capacity, MFCs working with Raney nickel-based cathodes reach higher values of chemical oxygen demand removal (76%) compared with the performance displayed by the cathodes based on Fe-complex (56%). PMID- 29455623 TI - Rare case of bilateral aural atresia and cochlear dysplasia: when cochlear implantation is not the answer. AB - OBJECTIVE AND IMPORTANCE: Reports of patients with concurrent middle and inner ear anomalies are rare. These patients present a surgical challenge for cochlear implantation. The surgical risk must be weighed against the predicted benefit of the patient's hearing outcome and subsequent development of speech and language as well as their quality of life. CLINICAL PRESENTATION: Thirteen-year-old boy presented to the Otology clinic for auditory rehabilitation options. He has mild developmental delay, is non-verbal and communicates via American Sign Language. He was born with bilateral aural atresia and never wore amplification. On exam he has grade 1 microtia and complete ear canal atresia bilaterally. His behavioural hearing test shows profound sensorineural hearing loss of both ears. The computed tomography scan shows bilateral underdeveloped and completely opacified mastoid and middle ear, complete bony atresia of the ear canals, and an under-partitioned cochlea with poorly defined modiolus, among other abnormalities. The patient and his family were counselled on the available options as well as the need for any further studies. INTERVENTION: Counselling of patient and family. CONCLUSION: While there have been reports in the literature of performing cochlear implantations in patients with a concurrent atresia and cochlear dysplasia, these were patients whose degree of inner ear anomalies was relatively minor and their prognosis of a good audiological outcome was favourable. The presented case is that of a patient for whom the surgical approach to the cochlea alone would be difficult. More importantly, his quality of life would not significantly improve in light of the predicted limited hearing and language development outcomes, given the severity of his inner ear abnormalities, limited communication abilities, prolonged period of deafness and developmental delays. PMID- 29455624 TI - Electrospinning of Polycaprolactone/Pluronic F127 dissolved in glacial acetic acid: fibrous scaffolds fabrication, characterization and in vitro evaluation. AB - Abstracts The Polycaprolactone (PCL) fibrous scaffolds in nano to micro scale have been considered as excellent templates for cell culture and tissue growth. The hydrophobic nature of the PCL, however, yields low initial cell seeding density, heterogeneous cell spreading and slow cell growth rate. Therefore, in this study the surface hydrophilic fibrous scaffolds were directly fabricated by the electrospinning of PCL solutions with small quantities (0.5-5%) of Pluronic F127 (PEO100-PPO65-PEO100) dissolved in benign solvent of glacial acetic acid. The clear and miscible solutions were achieved by controlling the proper F127 content in the blend solutions. The continuous and smooth fibers with average diameters from 0.71 to 1.43 MUm made up the fibrous scaffolds in non-woven mode. Then the water wetting angle of the scaffolds could be adjusted from 126 degrees to 0 degrees by varying F127 content owing to its hydrophilic PEO chains presented on surface the blended fibers. Finally, it was demonstrated that the blended fibrous scaffolds with the F127 content less than 1% exhibited better cell attachment, proliferation and spreading performance than those of pure PCL scaffolds. PMID- 29455625 TI - Diarrhea caused by rotavirus A, B, and C in suckling piglets from southern Brazil: molecular detection and histologic and immunohistochemical characterization. AB - Rotavirus (RV) is an important viral pathogen causing diarrhea in piglets and other mammals worldwide. We describe 34 cases from 4 diarrheal outbreaks caused by RV in unvaccinated farrowing units in southern Brazil from 2011 to 2013. We performed autopsy, histologic examinations, bacterial culture, RV immunohistochemistry (IHC), and enteric virus detection through molecular assays for rotavirus A, B, and C, transmissible gastroenteritis virus, porcine epidemic diarrhea virus, sapovirus, norovirus, and kobuvirus. Histologically, villus atrophy (29 of 34) and epithelial vacuolation (27 of 34) occurred in all 4 outbreaks. Cell debris in the lamina propria occurred in 20 cases, mostly from outbreaks A (8 of 11), C (4 of 6), and D (7 of 11). IHC was positive for RV in 21 of 34 samples. RT-PCR was positive for RV in 20 of 30 samples; RV-C was the most frequently detected RV ( n = 17). Kobuvirus was detected in 11 samples, and, in 3 of them, there was single detection of this enteric virus. PMID- 29455626 TI - Diagnosis of anaplastic large-cell lymphoma in a dog using CD30 immunohistochemistry. AB - Anaplastic large-cell lymphoma or null-cell lymphoma is a clinical entity reported in people, classified according to the unique appearance of large pleomorphic cells that express CD30. Null-cell lymphoma has also been described in dogs when neither CD3 nor CD79alpha is expressed by the tumor. We describe a case of lymphoma in the dog in which neoplastic cells did not express routine B- or T-lymphocyte markers on flow cytometry or immunohistochemistry; however, cells immunohistochemically labeled for CD30. The dog in our case died 5 mo after initial presentation, confirming a poor prognosis. Identification of further similar cases in dogs would provide additional prognostic information for this subset of lymphomas. CD30 may also serve as a potential therapeutic target in anaplastic large-cell lymphomas. PMID- 29455627 TI - Gastrointestinal spindle cell tumor of the rumen with metastasis to the liver in a goat. AB - Many neoplasms have been reported in goats; however, neoplasia of the rumen is rarely reported. A 9-y-old castrated male pygmy goat was presented with a history of respiratory stertor, fever, and anorexia. A respiratory diagnostic work-up including skull and thorax radiographs and endoscopy revealed minor enlargement of the arytenoids but no other abnormal findings. After a month of little improvement on symptomatic treatment and worsening general health, the goat was euthanized. On autopsy, the forestomachs, liver, spleen, diaphragm, and the ventral and lateral aspects of the cranial third of the walls of the peritoneal cavity were adhered to one another by fibrinous and fibrous adhesions. Numerous firm, white, up to 2 cm diameter nodules were found throughout the liver. A large sessile mass extended from the rumen wall into the lumen. The rumen mass was a gastrointestinal stromal tumor with metastasis to the liver. PMID- 29455628 TI - Nga Whakawhitinga (standing at the crossroads): How Maori understand what Western psychiatry calls "schizophrenia". AB - This project explored how Maori understand experiences commonly labelled "schizophrenic" or "psychotic". Semi-structured interviews were conducted with 57 Maori participants who had either personal experiences labelled as "psychosis" or "schizophrenia", or who work with people with such experiences; including tangata whaiora (users of mental health services), tohunga (traditional healers), kaumatua/kuia (elders), Maori clinicians, cultural support workers and students. Kaupapa Maori Theory and Personal Construct Theory guided the research within a qualitative methodology. The research found that participants held multiple explanatory models for experiences commonly labelled "psychotic" or "schizophrenic". The predominant explanations were spiritual and cultural. It seems that cultural beliefs and practices related to mental health within Maori communities remain resilient, despite over a century of contact with mainstream education and health services. Other explanations included psychosocial constructions (interpersonal trauma and drug abuse), historical trauma (colonisation) and biomedical constructions (chemical brain imbalance). Participants (both tangata whaiora and health professionals) reported they were apprehensive about sharing their spiritual/cultural constructions within mainstream mental health settings due to fear of being ignored or pathologised. This study highlights the importance of asking users of mental health services about the meaning they place on their experiences and recognising that individuals can hold multiple explanatory models. Maori may hold both Maori and Pakeha (European) ways of understanding their experiences and meaningful recognition should be afforded to both throughout assessment and treatment planning in mental health services. Clinicians need to be aware that important personal and cultural meanings of experiences labelled psychotic may be withheld due to fear of judgement or stigmatisation. PMID- 29455629 TI - Functional outcome of open surgical A1 pulley release in diabetic and nondiabetic patients. AB - PURPOSE: Trigger finger, also referred to as stenotic flexor tenosynovitis, is a common condition affecting the digits, with a lifetime incidence of 2.6% among the healthy population and up to 16.5% in diabetic patients. Diabetes mellitus is associated with multiple musculoskeletal conditions including trigger finger. In this study, we aimed to compare the functional outcome of trigger finger release in diabetic and nondiabetic patients to evaluate whether the management of trigger finger in diabetic patients should be the same as that in nondiabetic patients, or whether diabetic patients would benefit from a more tailored management plan to optimize results. METHODS: A retrospective case-control study was performed at a single center among patients who underwent A1 pulley release from January 2013 to February 2017. Patients were diagnosed with trigger finger grades I to IV according to the Quinnell classification and assessed using the The Disabilities of the Arm, Shoulder, and Hand (QuickDASH) questionnaire (Arabic version). RESULTS: Sixty-nine patients, including 21 male (30.4%) and 48 female (69.6%), underwent A1 pulley release surgery. More than half of the participants included in this study were diabetic (n = 40, 58%) and 29 were nondiabetic (42%). The mean postoperative QuickDASH scores were 19.93 among diabetic patients and 17.15 among nondiabetic patients. There was no significant difference in the functional outcome between diabetic and nondiabetic ( p = 0.6) patients. CONCLUSIONS: The postoperative functional outcomes are similar in diabetic and nondiabetic patients. Therefore, the management of trigger finger should be the same in both groups. PMID- 29455630 TI - Cervical endoscopic spinal surgery: A review of the current literature. AB - Cervical endoscopic spinal surgery (CESS) is now regularly performed in some centres in the Far East, yet rarely in Europe and the United States. This review describes the application of CESS through anterior and posterior approaches with analysis of the available evidence supporting current techniques. An electronic literature search identified 52 papers and proceedings' abstracts of which 25 (16 anterior approach and 9 posterior approach) provided comparable clinical outcomes. The results revealed a good or excellent outcome from CESS in 91% (range 74-100%) with a complication rate of 5%. In a local cohort study, patients had 72% less neck pain (visual analogue scale rating) and 81% less arm pain at 6 months when CESS was used as an isolated procedure, and 74% less neck pain and 83% less arm pain when coupled with disc replacement or fusion at an adjacent level. PMID- 29455631 TI - Periosteal flap augmentation of the Modified Brostrom-Gould procedure for chronic lateral ankle instability. AB - INTRODUCTION: Chronic lateral ankle instability occurs in up to 20% of ankle injuries. Most can be treated conservatively, but surgical reconstruction is required if conservative treatment fails. Modified Brostrom-Gould procedure is an effective surgical treatment and the augmentation of this procedure with a periosteal flap may confer additional stability. We report on the outcome of a technique combining a modified Brostrom-Gould procedure augmented with a periosteal flap in patients with chronic lateral ankle instability. METHOD: Twenty-four males aged 18-42 (mean, 24) with chronic lateral ankle instability affecting 24 ankles underwent the modified Brostrom-Gould procedure augmented with a periosteal flap, and these surgeries were performed by a single surgeon. The mean follow-up period was 28.7 months. Patients were assessed pre- and post operatively with the American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hind foot score. RESULTS: Preoperatively, the mean AOFAS ankle and hind foot score was 67.38. Post-operatively, significant improvement was seen, with a score of 88.71 ( p < 0.05). None of the patients reported surgical or wound complications. CONCLUSION: The technique of modified Brostrom-Gould procedure with periosteal flap augmentation appears to be a simple and safe operation for chronic lateral ankle instability. Patients with poor quality local ligamentous tissue, obese patients or high demand athletes generally benefit from this procedure. It allows effective augmentation of the reconstruction without causing any harm to local tendons or using additional costly implants. PMID- 29455632 TI - Arthroscopic undersurface rotator cuff repair versus conventional arthroscopic double-row rotator cuff repair - Comparable results at 2-year follow-up. AB - AIM: The aim of our study is to compare the improvement in clinical outcomes after conventional arthroscopic double-row rotator cuff repair and arthroscopic undersurface rotator cuff repair. METHOD: A consecutive series of 120 patients who underwent arthroscopic rotator cuff repair was analysed. Sixty-one patients underwent conventional double-row rotator cuff repair and 59 patients underwent undersurface rotator cuff repair. Several clinical outcomes, including numerical pain rating scale (NPRS), constant shoulder score (CSS), Oxford shoulder score (OSS) and University of California Los Angeles shoulder score (UCLASS), were prospectively recorded by a trained healthcare professional preoperatively and at 3, 6, 12 and 24 months after surgery. RESULT: Comparing both groups, there were no differences in age, gender and preoperative NPRS, CSS, OSS and UCLASS. However, the tear size was 0.7 +/- 0.2 (95% confidence interval (CI) 0.3-1.1) cm larger in the conventional group ( p = 0.002). There was no difference in the improvement of NPRS, CSS, OSS and UCLASS at all time points of follow-up, that is, at 3, 6, 12 and 24 months after surgery. The duration of operation was shorter by 35 +/- 3 (95% CI 28-42) min in the undersurface group ( p < 0.001). CONCLUSION: Both arthroscopic undersurface rotator cuff repair and conventional arthroscopic double-row rotator cuff repair showed marked improvements in clinical scores when compared preoperatively, and there was no difference in improvements between both groups. Arthroscopic undersurface rotator cuff repair is a faster technique compared to the conventional arthroscopic double-row rotator cuff repair. PMID- 29455633 TI - Placental growth factor, vascular endothelial growth factor, and hypoxia inducible factor-1alpha in the placentas of women with pre-eclampsia. AB - BACKGROUND: Although the exact mechanism of pre-eclampsia - high blood pressure and proteinuria after 20 gestational weeks - is not yet fully understood, placental growth factor (PLGF), vascular endothelial growth factor (VEGF), and hypoxia-inducible factor (HIF) are known to play important roles in vascularization and in the pathology of pre-eclampsia. METHODS: PLGF, VEGF, and HIF-1alpha were evaluated by immunohistochemistry in the placentas of Sudanese women with mild or severe pre-eclampsia, and in normal controls. RESULTS: Sixty two women had severe pre-eclampsia, 102 had mild pre-eclampsia and 101 women served as healthy controls. Immunohistochemical staining of PLGF was significantly lower in placentas of women with severe pre-eclampsia (16%) compared with those with mild pre-eclampsia (8.8%) and placentas of normotensive women (40.6%; p < .001). Significantly more of the pre-eclamptic placentas expressed VEGF: in 32%, 17.6%, and 14.9% (p = .020) of the placentas of women with severe or mild pre-eclampsia and in controls, respectively. Significantly more of the pre-eclamptic placentas expressed HIF-1alpha: in 15%, 10.8%, and 5.0% of the placentas of women with severe or mild pre-eclampsia, and in controls, respectively (p = .044). CONCLUSION: The current study showed that PLGF, VEGF, and HIF-1alpha are involved in the pathophysiology of pre-eclampsia. PMID- 29455634 TI - Early Predictors of Global Functional Outcome after Traumatic Spinal Cord Injury: A Systematic Review. AB - Accurately predicting functional recovery is an asset for all clinicians and decision makers involved in the care of patients with acute traumatic spinal cord injury (TSCI). Unfortunately, there is a lack of information on the relative importance of significant predictors of global functional outcome. There is also a need for identifying functional predictors that can be timely optimized by the medical and rehabilitation teams throughout the hospitalizations phases. The main objective of this work was to systematically review and rate early factors that are consistently and independently associated with global functional outcome in individuals with TSCI. A literature search using MEDLINE, EMBASE, and Cochrane databases from January 1, 1970 to April 1, 2017 was performed. Two authors independently reviewed the titles and abstracts yielded by this literature search and subsequently selected studies to be included based on predetermined eligibility criteria. Disagreements were resolved by a consensus-based discussion, and if not, by an external reviewer. Data were extracted by three independent reviewers using a standardized table. The quality of evidence of the individual studies was assessed based on the Oxford Center for Evidence-Based Medicine modified by Wright and colleagues (2000) as well as the National Institutes of Health (2014). Fifteen articles identifying early clinical predictors of functional outcome using multiple regression analyses were included in this systematic review. Based on the compiled data, this review proposes a rating of early factors associated to global functional outcome according to their importance and their potential to be modified by the medical/rehabilitation team throughout the early phases of hospitalization. It also proposes a new conceptual framework that illustrates the impact of specific categories of factors and their interaction with each other. Ultimately, this review aims to guide clinicians and researchers in improving the continuum of care throughout early phases post-SCI. PMID- 29455635 TI - The efficacy and safety of methotrexate versus interferon in cutaneous T-cell lymphomas. AB - OBJECTIVES: Methotrexate (MTX) and interferon (IFN) have been used in the treatment of cutaneous T-cell lymphomas (CTCL) of various subtypes. We review our experience of MTX and IFN use in our patients with CTCL at a tertiary hospital. MATERIALS AND METHODS: Medical records of patients over 4 years were reviewed. We describe the dosages, time to response, response rates, side effects, progression rate, and reasons for discontinuation. RESULTS: Response rate was significantly higher in the IFN group than MTX group (86.67% and 47.4% respectively, p = .01). Disease progression occurred 57.89% in the MTX group whilst only 26.67% progressed with IFN therapy. Patients taking IFN therapy experienced proportionally more side effects of any type than those undertaking MTX treatment (86.67% vs. 47.37%, odds ratio 7.22). However, discontinuation rate in the IFN group (26.67%) was much lower than in the MTX arm (89.47%). CONCLUSIONS: The most significant finding of this study was that patients with CTCL treated with IFN had a better response rate and significantly shorter response time compared with those treated with MTX. Additionally, patients had less disease progression on IFN than with MTX regardless of subtype of T-cell lymphoma and stage of disease. PMID- 29455636 TI - Feasibility investigation of a multi soil layering bioreactor for domestic wastewater treatment. AB - In this study, a multi soil layering (MSL) bioreactor was constructed to treat synthetic domestic wastewater. Effects of hydraulic loading rate (HLR) on the performance of the MSL bioreactor for synthetic domestic wastewater treatment were investigated. Results showed that the MSL bioreactor exhibited a strong adaptability on the variation of HLR, when the HLR was adjusted to 400 L.m-2.d-1, average removal efficiencies of chemical oxygen demand (COD), ammonia, total nitrogen (TN), and total phosphorus (TP) reached 93.4%, 94.9%, 80.4%, and 94.7%, respectively, which meet to the 1A discharge standard of the Discharge standard of pollutants for municipal wastewater treatment plant (GB 18918-2002). In the treatment process by the MSL bioreactor, biological decomposition and biotransformation processes of microorganisms was the most important pathway for COD, ammonia, and TN removal, while TP was removed by the chemical reaction with ferric ion. Nitrobacteria, ciliate, rotifer and epistylis were in large numbers in the operating phase, indicated that the biofilm was matured with a high quality and the MSL bioreactor was effective for domestic wastewater treatment. PMID- 29455637 TI - Molecular dynamics of interaction of Sesamin and related compounds with the cancer marker beta-catenin: an in silico study. AB - By virtue of their regulatory role in the biological process, certain protein protein complexes form potential targets for designing and discovery of drugs. Alteration set in the controlled formation of such complexes results in dysregulation of several metabolic processes, leading to diseased condition. beta catenin/Tcf4 complex is one such protein-protein complex found altered in colorectal epithelial cells resulting in activation of target genes leading to cancer. Recently, certain lignans from seeds of the oil crop sesame were found inhibiting initiation and progression of this type of cancer. Molecular mechanism involved in the process, however, is not yet known. By an in silico study, we present here a possible mechanism of interaction between the sesame lignans and beta-catenin leading to inhibition of formation of the said complex, thereby elevating some of these ligands as potential lead molecules in the development of drugs for treatment of colon cancer. To achieve this objective, we performed docking, molecular dynamics simulation, and binding free energy analysis of target-ligand complexes. Using computational alanine scanning approach, the key pocket residues of beta-catenin that interact with Tcf4 in the formation of complex were identified. The test molecules were initially evaluated for their drug-like properties by application of Lipinski's rule of five. Results of this study revealed that Sesamin, a furofuran lignan from sesame, has the highest affinity for beta-catenin particularly with its residues that interact with Tcf4 and thus serving as a potential lead molecule for development of a drug for colon cancer. PMID- 29455638 TI - Clinicopathologic and Prognostic Significance of Programmed Cell Death Ligand 1 Expression in Patients with Non-Medullary Thyroid Cancer: A Systematic Review and Meta-Analysis. AB - BACKGROUND: Evidence has shown that programmed cell death ligand 1 (PD-L1) overexpression is associated with poor prognosis and resistance to immune therapies in several human cancers. However, data on the prognostic significance of PD-L1 expression in thyroid cancer are limited and remain controversial. This systematic review and meta-analysis aimed to evaluate comprehensively the clinicopathologic significance and prognostic value of PD-L1 expression in non medullary thyroid cancers. METHODS: Electronic databases, including Medline/PubMed, EMBASE, and the Cochrane Library, were searched up until July 5, 2017. In total, seven comparisons (from six articles) comprising 1421 patients were included in the pooled analysis. RESULTS: There was moderate quality evidence from four studies (n = 721) that shows positive PD-L1 expression was significantly associated with poor survival among thyroid cancer patients (pooled hazard ratio = 3.73 [confidence interval (CI) 2.75-5.06]). Increased PD-L1 expression was also found to be significantly associated with disease recurrence (odds ratio = 1.95 [CI 1.15-3.32]) and concurrent thyroiditis (odds ratio = 1.65 [CI 1.09-2.51]). CONCLUSIONS: The results confirm the prognostic significance of PD-L1 expression in thyroid cancer patients. PD-L1 expression has the potential to be implemented as a prognostic biomarker used to guide clinicians in identifying patients with more aggressive cancers, and for the selection of individuals that would derive durable clinical benefit from anti-PD-1/PD-L1 immunotherapy. Prospective clinical trials will be useful to support these findings. PMID- 29455640 TI - CCL2/CCL5 secreted by the stroma induce IL-6/PYK2 dependent chemoresistance in ovarian cancer. AB - BACKGROUND: Minimal residual disease is the main issue of advanced ovarian cancer treatment. According to the literature and previous results, we hypothesized that Mesenchymal Stromal Cells (MSC) could support this minimal residual disease by protecting ovarian cancer cells (OCC) from chemotherapy. In vitro study confirmed that MSC could induce OCC chemoresistance without contact using transwell setting. Further experiments showed that this induced chemoresistance was dependent on IL-6 OCC stimulation. METHODS: We combined meticulous in vitro profiling and tumor xenograft models to study the role of IL-6 in MSC/OCC intereactions. RESULTS: We demonstrated that Tocilizumab(r) (anti-IL-6R therapy) in association with chemotherapy significantly reduced the peritoneal carcinosis index (PCI) than chemotherapy alone in mice xenografted with OCCs+MSCs. Further experiments showed that CCL2 and CCL5 are released by MSC in transwell co-culture and induce OCCs IL-6 secretion and chemoresistance. Finally, we found that IL-6 induced chemoresistance was dependent on PYK2 phosphorylation. CONCLUSIONS: These findings highlight the potential key role of the stroma in protecting minimal residual disease from chemotherapy, thus favoring recurrences. Future clinical trials targeting stroma could use anti-IL-6 therapy in association with chemotherapy. PMID- 29455641 TI - Circadian pathway genetic variation and cancer risk: evidence from genome-wide association studies. AB - BACKGROUND: Dysfunction of the circadian clock and single polymorphisms of some circadian genes have been linked to cancer susceptibility, although data are scarce and findings inconsistent. We aimed to investigate the association between circadian pathway genetic variation and risk of developing common cancers based on the findings of genome-wide association studies (GWASs). METHODS: Single nucleotide polymorphisms (SNPs) of 17 circadian genes reported by three GWAS meta analyses dedicated to breast (Discovery, Biology, and Risk of Inherited Variants in Breast Cancer (DRIVE) Consortium; cases, n = 15,748; controls, n = 18,084), prostate (Elucidating Loci Involved in Prostate Cancer Susceptibility (ELLIPSE) Consortium; cases, n = 14,160; controls, n = 12,724) and lung carcinoma (Transdisciplinary Research In Cancer of the Lung (TRICL) Consortium; cases, n = 12,160; controls, n = 16,838) in patients of European ancestry were utilized to perform pathway analysis by means of the adaptive rank truncated product (ARTP) method. Data were also available for the following subgroups: estrogen receptor negative breast cancer, aggressive prostate cancer, squamous lung carcinoma and lung adenocarcinoma. RESULTS: We found a highly significant statistical association between circadian pathway genetic variation and the risk of breast (pathway P value = 1.9 * 10-6; top gene RORA, gene P value = 0.0003), prostate (pathway P value = 4.1 * 10-6; top gene ARNTL, gene P value = 0.0002) and lung cancer (pathway P value = 6.9 * 10-7; top gene RORA, gene P value = 2.0 * 10-6), as well as all their subgroups. Out of 17 genes investigated, 15 were found to be significantly associated with the risk of cancer: four genes were shared by all three malignancies (ARNTL, CLOCK, RORA and RORB), two by breast and lung cancer (CRY1 and CRY2) and three by prostate and lung cancer (NPAS2, NR1D1 and PER3), whereas four genes were specific for lung cancer (ARNTL2, CSNK1E, NR1D2 and PER2) and two for breast cancer (PER1, RORC). CONCLUSIONS: Our findings, based on the largest series ever utilized for ARTP-based gene and pathway analysis, support the hypothesis that circadian pathway genetic variation is involved in cancer predisposition. PMID- 29455639 TI - Role of Bruton's tyrosine kinase in B cells and malignancies. AB - Bruton's tyrosine kinase (BTK) is a non-receptor kinase that plays a crucial role in oncogenic signaling that is critical for proliferation and survival of leukemic cells in many B cell malignancies. BTK was initially shown to be defective in the primary immunodeficiency X-linked agammaglobulinemia (XLA) and is essential both for B cell development and function of mature B cells. Shortly after its discovery, BTK was placed in the signal transduction pathway downstream of the B cell antigen receptor (BCR). More recently, small-molecule inhibitors of this kinase have shown excellent anti-tumor activity, first in animal models and subsequently in clinical studies. In particular, the orally administered irreversible BTK inhibitor ibrutinib is associated with high response rates in patients with relapsed/refractory chronic lymphocytic leukemia (CLL) and mantle cell lymphoma (MCL), including patients with high-risk genetic lesions. Because ibrutinib is generally well tolerated and shows durable single-agent efficacy, it was rapidly approved for first-line treatment of patients with CLL in 2016. To date, evidence is accumulating for efficacy of ibrutinib in various other B cell malignancies. BTK inhibition has molecular effects beyond its classic role in BCR signaling. These involve B cell-intrinsic signaling pathways central to cellular survival, proliferation or retention in supportive lymphoid niches. Moreover, BTK functions in several myeloid cell populations representing important components of the tumor microenvironment. As a result, there is currently a considerable interest in BTK inhibition as an anti-cancer therapy, not only in B cell malignancies but also in solid tumors. Efficacy of BTK inhibition as a single agent therapy is strong, but resistance may develop, fueling the development of combination therapies that improve clinical responses. In this review, we discuss the role of BTK in B cell differentiation and B cell malignancies and highlight the importance of BTK inhibition in cancer therapy. PMID- 29455642 TI - Role and targeting of anaplastic lymphoma kinase in cancer. AB - Anaplastic lymphoma kinase (ALK) gene activation is involved in the carcinogenesis process of several human cancers such as anaplastic large cell lymphoma, lung cancer, inflammatory myofibroblastic tumors and neuroblastoma, as a consequence of fusion with other oncogenes (NPM, EML4, TIM, etc) or gene amplification, mutation or protein overexpression. ALK is a transmembrane tyrosine kinase receptor that, upon ligand binding to its extracellular domain, undergoes dimerization and subsequent autophosphorylation of the intracellular kinase domain. When activated in cancer it represents a target for specific inhibitors, such as crizotinib, ceritinib, alectinib etc. which use has demonstrated significant effectiveness in ALK-positive patients, in particular ALK-positive non- small cell lung cancer. Several mechanisms of resistance to these inhibitors have been described and new strategies are underway to overcome the limitations of current ALK inhibitors. PMID- 29455644 TI - miR-19b enhances proliferation and apoptosis resistance via the EGFR signaling pathway by targeting PP2A and BIM in non-small cell lung cancer. AB - BACKGROUND: Epidermal growth factor receptor (EGFR) mutations enable constitutive active downstream signaling of PI3K/AKT, KRAS/ERK and JAK/STAT pathways, and promote tumor progression by inducing uncontrolled proliferation, evasion of apoptosis and migration of non-small cell lung cancer (NSCLC). In addition, such EGFR mutations increase the susceptibility of patients with NSCLC to tyrosine kinase inhibitor (TKI) therapy, but treated patients will invariably relapse with resistant disease. A global understanding of underlying molecular mechanisms of EGFR signaling may improve the management of NSCLC patients. METHODS: microarray analysis was performed to identify PI3K/AKT-regulated miRNAs. Phosphoproteomic analysis and cell based assays were performed using NSCLC cell lines lentivirally transduced with anti-miR or miR overexpressing constructs. RESULTS: Here, we show that 17 miRNAs including members of the miR-17~ 92 cluster are dysregulated following PI3K/AKT inhibition of EGFR mutant NSCLC cells. Bioinformatics analysis revealed that dysregulated miRNAs act in a concerted manner to enhance the activity of the EGFR signaling pathway. These findings were closely mirrored by attenuation of miR-17~ 92 family member miR-19b in NSCLC cell lines which resulted in reduced phosphorylation of ERK, AKT and STAT and effector proteins in EGFR mutant NSCLC cells. Consistent with this finding, cell cycle progression, clonogenic growth and migration were reduced and apoptosis was enhanced. Co treatment of NSCLC cells with the tyrosine kinase inhibitor (TKI) gefitinib and anti-miR-19b construct reduced migration and clonogenic growth in a synergistic manner suggesting that EGFR and miR-19b act together to control oncogenic processes. Serine/threonine phosphatase PP2A subunit PPP2R5E and BCL2L11 encoding BIM were identified as major targets of miR-19b by target validation assays. Consistent with this finding, PP2A activity was strongly enhanced in NSCLC transduced with anti-miR-19b construct, but not in cells co-transduced with anti miR-19b and shPPP2R5E, suggesting that PPP2R5E is a major constituent of the PP2A complex. Accordingly, enhanced proliferation by miR-19b was due to targeting PPP2R5E. In contrast, apoptosis resistance was mainly due to targeting BCL2L11. CONCLUSION: Our results provide insight into the importance of targeting PPP2R5E and BCL2L11 by miR-19b in oncogenic processes of NSCLC. Attenuation of miR-19b expression could potentially be exploited in adjuvant therapy of EGFR mutant NSCLC. PMID- 29455643 TI - Chronic myeloid leukemia: the paradigm of targeting oncogenic tyrosine kinase signaling and counteracting resistance for successful cancer therapy. AB - Deregulated activity of BCR-ABL1, a nonreceptor tyrosine kinase encoded by the fusion gene resulting from the t(9;22)(q34;q11) chromosomal translocation, is thought to be the driver event responsible for initiation and maintenance of chronic myeloid leukemia (CML). BCR-ABL1 was one of the first tyrosine kinases to be implicated in a human malignancy and the first to be successfully targeted. Imatinib mesylate, the first tyrosine kinase inhibitor (TKI) to be approved for therapeutic use, was hailed as a magic bullet against cancer and remains one of the safest and most effective anticancer agents ever developed. Second- and third generation TKIs were later introduced to prevent or counteract the problem of drug resistance, that may arise in a small proportion of patients. They are more potent molecules, but have been associated to more serious side effects and complications. Patients achieving stable optimal responses to TKI therapy are predicted to have the same life expectancy of the general population. However, TKIs do not 'cure' CML. Only a small proportion of cases may attempt therapy discontinuation without experiencing subsequent relapse. The great majority of patients will have to assume TKIs indefinitely - which raises serious pharmacoeconomic concerns and is now shifting the focus from efficacy to compliance and quality of life issues. Here we retrace the steps that have led from the biological acquisitions regarding BCR-ABL1 structure and function to the development of inhibitory strategies and we discuss drug resistance mechanism and how they can be addressed. PMID- 29455645 TI - Pyruvate kinase M2 fuels multiple aspects of cancer cells: from cellular metabolism, transcriptional regulation to extracellular signaling. AB - Originally identified as a metabolic enzyme that catalyzes the transfer of a phosphate group from phosphoenolpyruvate (PEP) to ADP in the glycolytic pathway, pyruvate kinase M2-type (PKM2) has been shown to exhibit novel biological activities in the nucleus and outside the cells. Although cell-based studies reveal new non-canonical functions of PKM2 in gene transcription, epigenetic modulation and cell cycle progression, the importance of these non-canonical functions in PKM2-mediated tumorigenesis is still under debate because studies in genetically modified mice do not consistently echo the findings observed in cultured cancer cells. In addition to regulation of gene expression, the existence of PKM2 in exosomes opens a new venue to study the potential role of this glycolytic enzyme in cell-cell communication and extracellular signal initiation. In this review, we briefly summarize current understanding of PKM2 in metabolic switch and gene regulation. We will then emphasize recent progress of PKM2 in extracellular signaling and tumor microenvironment reprogramming. Finally, the discrepancy of some PKM2's functions in vitro and in vivo, and the application of PKM2 in cancer detection and treatment will be discussed. PMID- 29455646 TI - Tyrosine kinase inhibitors enhanced the efficacy of conventional chemotherapeutic agent in multidrug resistant cancer cells. AB - Multidrug resistance (MDR) triggered by ATP binding cassette (ABC) transporter such as ABCB1, ABCC1, ABCG2 limited successful cancer chemotherapy. Unfortunately, no commercial available MDR modulator approved by FDA was used in clinic. Tyrosine kinase inhibitors (TKIs) have been administrated to fight against cancer for decades. Almost TKI was used alone in clinic. However, drug combinations acting synergistically to kill cancer cells have become increasingly important in cancer chemotherapy as an approach for the recurrent resistant disease. Here, we summarize the effect of TKIs on enhancing the efficacy of conventional chemotherapeutic drug in ABC transporter-mediated MDR cancer cells, which encourage to further discuss and study in clinic. PMID- 29455647 TI - 99mTc-HYNIC-(tricine/EDDA)-FROP peptide for MCF-7 breast tumor targeting and imaging. AB - BACKGROUND: Breast cancer is the most common malignancy among women in the world. Development of novel tumor-specific radiopharmaceuticals for early breast tumor diagnosis is highly desirable. In this study we developed 99mTc-HYNIC (tricine/EDDA)-Lys-FROP peptide with the ability of specific binding to MCF-7 breast tumor. METHODS: The FROP-1 peptide was conjugated with the bifunctional chelator hydrazinonicotinamide (HYNIC) and labeled with 99mTc using tricine/EDDA co-ligand. The cellular specific binding of 99mTc-HYNIC-FROP was evaluated on different cell lines as well as with blocking experiment on MCF-7 (human breast adenocarcinoma). The tumor targeting and imaging of this labeled peptide were performed on MCF-7 tumor bearing mice. RESULTS: Radiochemical purity for 99mTc HYNIC-(tricine/EDDA)-FROP was 99% which was determined with ITLC method. This radiolabeled peptide showed high stability in normal saline and serum about 98% which was monitored with HPLC method. In saturation binding experiments, the binding constant (Kd) to MCF-7 cells was determined to be 158 nM. Biodistribution results revealed that the 99mTc-HYNIC-FROP was mainly exerted from urinary route. The maximum tumor uptake was found after 30 min post injection (p.i.); however maximum tumor/muscle ratio was seen at 15 min p.i. The tumor uptake of this labeled peptide was specific and blocked by co-injection of excess FROP. According to the planar gamma imaging result, tumor was clearly visible due to the tumor uptake of 99mTc-HYNIC-(tricine/EDDA)-FROP in mouse after 15 min p.i. CONCLUSIONS: The 99mTc-HYNIC-(tricine/EDDA)-FROP is considered a promising probe with high specific binding to MCF-7 breast cancer cells. PMID- 29455649 TI - Molecular subtyping of nasopharyngeal carcinoma (NPC) and a microRNA-based prognostic model for distant metastasis. AB - BACKGROUND: Nasopharyngeal carcinoma (NPC) is a highly invasive and metastatic cancer, with diverse molecular characteristics and clinical outcomes. This study aims to dissect the molecular heterogeneity of NPC, followed by the construction of a microRNA (miRNA)-based prognostic model for prediction of distant metastasis. METHODS: We retrieved two NPC datasets: GSE32960 and GSE70970 as training and validation cohorts, respectively. Consensus clustering was employed for cluster discovery, and support vector machine was used to build a classifier. Finally, Cox regression analysis was applied to constructing a prognostic model for predicting risk of distant metastasis. RESULTS: Three NPC subtypes (immunogenic, classical and mesenchymal) were identified that are molecularly distinct and clinically relevant, of which mesenchymal subtype (~ 36%) is associated with poor prognosis, characterized by suppressing tumor suppressor miRNAs and the activation of epithelial--mesenchymal transition. Out of the 25 most differentially expressed miRNAs in mesenchymal subtype, miR-142, miR-26a, miR-141 and let-7i have significant prognostic power (P < 0.05). CONCLUSIONS: We proposed for the first time that NPC can be stratified into three subtypes. Using a panel of 4 miRNAs, we established a prognostic model that can robustly stratify NPC patients into high- and low- risk groups of distant metastasis. PMID- 29455648 TI - Mechanisms of receptor tyrosine kinase activation in cancer. AB - Receptor tyrosine kinases (RTKs) play an important role in a variety of cellular processes including growth, motility, differentiation, and metabolism. As such, dysregulation of RTK signaling leads to an assortment of human diseases, most notably, cancers. Recent large-scale genomic studies have revealed the presence of various alterations in the genes encoding RTKs such as EGFR, HER2/ErbB2, and MET, amongst many others. Abnormal RTK activation in human cancers is mediated by four principal mechanisms: gain-of-function mutations, genomic amplification, chromosomal rearrangements, and / or autocrine activation. In this manuscript, we review the processes whereby RTKs are activated under normal physiological conditions and discuss several mechanisms whereby RTKs can be aberrantly activated in human cancers. Understanding of these mechanisms has important implications for selection of anti-cancer therapies. PMID- 29455650 TI - Management of acquired resistance to EGFR TKI-targeted therapy in advanced non small cell lung cancer. AB - Recent advances in diagnosis and treatment are enabling a more targeted approach to treating lung cancers. Therapy targeting the specific oncogenic driver mutation could inhibit tumor progression and provide a favorable prognosis in clinical practice. Activating mutations of epidermal growth factor receptor (EGFR) in non-small cell lung cancer (NSCLC) are a favorable predictive factor for EGFR tyrosine kinase inhibitors (TKIs) treatment. For lung cancer patients with EGFR-exon 19 deletions or an exon 21 Leu858Arg mutation, the standard first line treatment is first-generation (gefitinib, erlotinib), or second-generation (afatinib) TKIs. EGFR TKIs improve response rates, time to progression, and overall survival. Unfortunately, patients with EGFR mutant lung cancer develop disease progression after a median of 10 to 14 months on EGFR TKI. Different mechanisms of acquired resistance to first-generation and second-generation EGFR TKIs have been reported. Optimal treatment for the various mechanisms of acquired resistance is not yet clearly defined, except for the T790M mutation. Repeated tissue biopsy is important to explore resistance mechanisms, but it has limitations and risks. Liquid biopsy is a valid alternative to tissue re-biopsy. Osimertinib has been approved for patients with T790M-positive NSCLC with acquired resistance to EGFR TKI. For other TKI-resistant mechanisms, combination therapy may be considered. In addition, the use of immunotherapy in lung cancer treatment has evolved rapidly. Understanding and clarifying the biology of the resistance mechanisms of EGFR-mutant NSCLC could guide future drug development, leading to more precise therapy and advances in treatment. PMID- 29455651 TI - Targeting few to help hundreds: JAK, MAPK and ROCK pathways as druggable targets in atypical chronic myeloid leukemia. AB - Atypical Chronic Myeloid Leukemia (aCML) is a myeloproliferative neoplasm characterized by neutrophilic leukocytosis and dysgranulopoiesis. From a genetic point of view, aCML shows a heterogeneous mutational landscape with mutations affecting signal transduction proteins but also broad genetic modifiers and chromatin remodelers, making difficult to understand the molecular mechanisms causing the onset of the disease. The JAK-STAT, MAPK and ROCK pathways are known to be responsible for myeloproliferation in physiological conditions and to be aberrantly activated in myeloproliferative diseases. Furthermore, experimental evidences suggest the efficacy of inhibitors targeting these pathways in repressing myeloproliferation, opening the way to deep clinical investigations. However, the activation status of these pathways is rarely analyzed when genetic mutations do not occur in a component of the signaling cascade. Given that mutations in functionally unrelated genes give rise to the same pathology, it is tempting to speculate that alteration in the few signaling pathways mentioned above might be a common feature of pathological myeloproliferation. If so, targeted therapy would be an option to be considered for aCML patients. PMID- 29455652 TI - Expression, regulation and targeting of receptor tyrosine kinases in esophageal squamous cell carcinoma. AB - Esophageal cancer is one of the most common types of cancer, which is a leading cause of cancer-related death worldwide. Based on histological behavior, it is mainly of two types (i) Esophageal squamous cell carcinoma (ESCC), and (ii) esophageal adenocarcinoma (EAD or EAC). In astronomically immense majority of malignancies, receptor tyrosine kinases (RTKs) have been kenned to play a consequential role in cellular proliferation, migration, and metastasis of the cells. The post-translational modifications (PTMs) including phosphorylation of tyrosine (pY) residue of the tyrosine kinase (TK) domain have been exploited for treatment in different malignancies. Lung cancer where pY residues of EGFR have been exploited for treatment purpose in lung adenocarcinoma patients, but we do not have such kind of felicitously studied and catalogued data in ESCC patients. Thus, the goal of this review is to summarize the studies carried out on ESCC to explore the role of RTKs, tyrosine kinase inhibitors, and their pertinence and consequentiality for the treatment of ESCC patients. PMID- 29455654 TI - Third generation EGFR TKIs: current data and future directions. AB - Acquired T790 M mutation is the commonest cause of resistance for advanced non small cell lung cancer (NSCLC) epidermal growth factor receptor (EGFR) mutant patients who had progressed after first line EGFR TKI (tyrosine kinase inhibitor). Several third generation EGFR TKIs which are EGFR mutant selective and wild-type (WT) sparing were developed to treat these patients with T790 M acquired resistant mutation. Osimertinib is one of the third generation EGFR TKIs and is currently the most advanced in clinical development. Unfortunately, despite good initial response, patients who was treated with third generation EGFR TKI would develop acquired resistance and several mechanisms had been identified and the commonest being C797S mutation at exon 20. Several novel treatment options were being developed for patients who had progressed on third generation EGFR TKI but they are still in the early phase of development. Osimertinib under FLAURA study had been shown to have better progression-free survival over first generation EGFR TKI in the first line setting and likely will become the new standard of care. PMID- 29455653 TI - Novel targeted therapies and immunotherapy for advanced thyroid cancers. AB - Thyroid cancer is a frequently encountered endocrine malignancy. Despite the favorable prognosis of this disease, 15-20% of differentiated thyroid cancer (DTC) cases and most anaplastic types, remain resistant to standard treatment options, including radioactive iodine (RAI). In addition, around 30% of medullary thyroid cancer (MTC) cases show resistance after surgery. The evolving understanding of disease-specific molecular therapeutic targets has led to the approval of two targeted therapies (Sorafenib and Lenvatinib) for RAI refractory DTC and another two drugs (Vandetanib and Cabozantinib) for MTC. These advanced therapies exert their effects by blocking the MAPK pathway, which has been widely correlated to different types of thyroid cancers. While these drugs remain reserved for thyroid cancer patients who failed all treatment options, their ability to improve patients' overall survival remain hindered by their low efficacy and other molecular factors. Among these factors is the tumor's ability to activate parallel proliferative signaling pathways other than the cascades blocked by these drugs, along with overexpression of some tyrosine kinase receptors (TKR). These facts urge the search for novel different treatment strategies for advanced thyroid cases beyond these drugs. Furthermore, the growing knowledge of the dynamic immune system interaction with tumor microenvironment has revolutionized the cancer immune therapy field. In this review, we aim to discuss the molecular escape mechanisms of thyroid tumors from these drugs. We also highlight novel therapeutic options targeting other pathways than MAPK, including PI3K pathway, ALK translocations and HER2/3 receptors and their clinical impact. We also aim to discuss the usage of targeted therapy in restoring thyroid tumor sensitivity to RAI, and finally turn to extensively discuss the role of immunotherapy as a potential alternative treatment option for advanced thyroid diseases. PMID- 29455655 TI - Disruption of ETV6 leads to TWIST1-dependent progression and resistance to epidermal growth factor receptor tyrosine kinase inhibitors in prostate cancer. AB - BACKGROUND: ETS variant gene 6 (ETV6) is a putative tumor suppressor and repressed by epidermal growth factor receptor (EGFR) signaling in prostate cancer. Since EGFR antagonists seem ineffective in castration-resistant prostate cancer (CRPC), we aim to study the role of ETV6 in the development of drug resistance. METHODS: Etv6 target gene was validated by ChIP and promoter reporter assays. Correlation of ETV6 and TWIST1 was analyzed in human clinical datasets and tissue samples. Migration, invasion, and metastasis assays were used to measure the cellular responses after perturbation of ETV6 -TWIST1 axis. Proliferation and tumor growth in xenograft model were performed to evaluate the drug sensitivities of EGFR-tyrosine kinase inhibitors (TKIs). RESULTS: ETV6 inhibits TWIST1 expression and disruption of ETV6 promotes TWIST1-dependent malignant phenotypes. Importantly, ETV6 is required to the anti-proliferation effects of EGFR-TKIs, partly due to the inhibitory function of ETV6 on TWIST1. We also found that EGFR-RAS signaling is tightly controlled by ETV6, supporting its role in TKI sensitivity. CONCLUSIONS: Our study demonstrates that disruption of ETV6 contributes to EGFR-TKI resistance, which is likely due to derepression of TWIST1 and activation of EGFR-RAS signaling. Our results implicate ETV6 as a potential marker for predicting efficacy of an EGFR-targeted anticancer approach. Combination treatment of TWIST1 inhibitors could sensitize the anti-proliferation effects of EGFR-TKIs. PMID- 29455656 TI - The E3 ubiquitin ligase NEDD4 mediates cell migration signaling of EGFR in lung cancer cells. AB - BACKGROUND: EGFR-dependent cell migration plays an important role in lung cancer progression. Our previous study observed that the HECT E3 ubiquitin ligase NEDD4 is significantly correlated with tumor metastasis and required for migration and invasion signaling of EGFR in gastric cancer cells. However, how NEDD4 promotes the EGFR-dependent lung cancer cell migration is unknown. This study is to elucidate the mechanism by which NEDD4 mediates the EGFR lung cancer migration signaling. METHODS: Lentiviral vector-loaded NEDD4 shRNA was used to deplete endogenous NEDD4 in lung cancer cell lines. Effects of the NEDD4 knockdown on the EGFR-dependent or independent lung cancer cell migration were determined using the wound-healing and transwell assays. Association of NEDD4 with activated EGFR was assayed by co-immunoprecipitation. Co-expression of NEDD4 with EGFR or PTEN was determined by immunohistochemical (IHC) staining in 63 lung adenocarcinoma tissue samples. Effects of NEDD4 ectopic expression or knockdown on PTEN ubiquitination and down-regulation, AKT activation and lysosomal secretion were examined using the GST-Uba pulldown assay, immunoblotting, immunofluorescent staining and a human cathepsin B ELISA assay respectively. The specific cathepsin B inhibitor CA-074Me was used for assessing the role of cathepsin B in lung cancer cell migration. RESULTS: Knockdown of NEDD4 significantly reduced EGF stimulated cell migration in non-small cell lung carcinoma (NSCLC) cells. Co immunoprecipitation assay found that NEDD4 is associated with EGFR complex upon EGF stimulation, and IHC staining indicates that NEDD4 is co-expressed with EGFR in lung adenocarcinoma tumor tissues, suggesting that NEDD4 might mediate lung cancer cell migration by interaction with the EGFR signaling complex. Interestingly, NEDD4 promotes the EGF-induced cathepsin B secretion, possibly through lysosomal exocytosis, as overexpression of the ligase-dead mutant of NEDD4 impedes lysosomal secretion, and knockdown of NEDD4 significantly reduced extracellular amount of cathepsin B induced by EGF. Consistent with the role of NEDD4, cathepsin B is pivotal for both basal and the EGF-stimulated lung cancer cell migration. Our studies propose a novel mechanism underlying the EGFR promoted lung cancer cell migration that is mediated by NEDD4 through regulation of cathepsin B secretion. CONCLUSION: NEDD4 mediates the EGFR lung cancer cell migration signaling through promoting lysosomal secretion of cathepsin B. PMID- 29455657 TI - Role of the HGF/c-MET tyrosine kinase inhibitors in metastasic melanoma. AB - Metastatic disease in a cancer patient still remains a therapeutic challenge. Metastatic process involves many steps, during which malignant cells succeed to activate cellular pathways promoting survival in hostile environment, engraftment and growth at the distant site from the primary tumor. Melanoma is known for its high propensity to produce metastases even at the early stages of the disease. Here we summarize the most important molecular mechanisms which were associated with the melanoma metastasis. Then, we specifically focus on the signaling pathway mediated by hepatocyte growth factor (HGF) and its receptor c-Met, which play an important role during physiological processes and were been associated with tumorigenesis. We also focus on the effect of the small molecule inhibitors of the tyrosine kinase domain of the c-Met receptor and its effects on properties of melanoma cell. We summarize recent studies, which involved inhibition of the HGF/c-Met signaling in order to decrease melanoma growth and metastatic capacity. PMID- 29455658 TI - Receptor tyrosine kinases (RTKs) in breast cancer: signaling, therapeutic implications and challenges. AB - Breast cancer is a multifactorial disease and driven by aberrant regulation of cell signaling pathways due to the acquisition of genetic and epigenetic changes. An array of growth factors and their receptors is involved in cancer development and metastasis. Receptor Tyrosine Kinases (RTKs) constitute a class of receptors that play important role in cancer progression. RTKs are cell surface receptors with specialized structural and biological features which respond to environmental cues by initiating appropriate signaling cascades in tumor cells. RTKs are known to regulate various downstream signaling pathways such as MAPK, PI3K/Akt and JAK/STAT. These pathways have a pivotal role in the regulation of cancer stemness, angiogenesis and metastasis. These pathways are also imperative for a reciprocal interaction of tumor and stromal cells. Multi-faceted role of RTKs renders them amenable to therapy in breast cancer. However, structural mutations, gene amplification and alternate pathway activation pose challenges to anti-RTK therapy. PMID- 29455659 TI - Receptor tyrosine kinases and downstream pathways as druggable targets for cancer treatment: the current arsenal of inhibitors. AB - Searching for targets that allow pharmacological inhibition of cell proliferation in over-proliferative states, such as cancer, leads us to finely understand the complex mechanisms orchestrating the perfect control of mitosis number, frequency and pace as well as the molecular arrangements that induce cells to enter functional quiescence and brings them back to cycling in specific conditions. Although the mechanisms regulating cell proliferation have been described several years ago, never before has so much light been shed over this machinery as during the last decade when therapy targets have been explored and molecules, either synthetic or in the form of antibodies with the potential of becoming cancer drugs were produced and adjusted for specific binding and function. Proteins containing tyrosine kinase domains, either membrane receptors or cytoplasmic molecules, plus the ones activated by those in downstream pathways, having tyrosine kinase domains or not, such as RAS which is a GTPase and serine/threonine kinases such as RAF, play crucial role in conducting proliferation information from cell surroundings to the nucleus where gene expression takes place. Tyrosine kinases phosphorylate tyrosine residues in an activating mode and are found in important growth factor receptors, such as for ligands from families collectively known as VEGF, PDGF and EGF, to name a few and in intracellular downstream molecules. They all play important roles in normal physiology and are commonly found mutated or overexpressed in neoplastic states. Our objective here is to present such kinases as druggable targets for cancer therapy, highlighting the ones for which the pharmacological arsenal is available, discussing specificity, resistance mechanisms and treatment alternatives in cases of resistance, plus listing potential targets that have not been successfully worked yet. PMID- 29455660 TI - The relevance of tyrosine kinase inhibitors for global metabolic pathways in cancer. AB - Tumor metabolism is a thrilling discipline that focuses on mechanisms used by cancer cells to earn crucial building blocks and energy to preserve growth and overcome resistance to various treatment modalities. At the same time, therapies directed specifically against aberrant signalling pathways driven by protein tyrosine kinases (TKs) involved in proliferation, metastasis and growth count for several years to promising anti-cancer approaches. In this respect, small molecule inhibitors are the most widely used clinically relevant means for targeted therapy, with a rising number of approvals for TKs inhibitors. In this review, we discuss recent observations related to TKs-associated metabolism and to metabolic feedback that is initialized as cellular response to particular TK targeted therapies. These observations provide collective evidence that therapeutic responses are primarily linked to such pathways as regulation of lipid and amino acid metabolism, TCA cycle and glycolysis, advocating therefore the development of further effective targeted therapies against a broader spectrum of TKs to treat patients whose tumors display deregulated signalling driven by these proteins. PMID- 29455661 TI - Development of a 4-aminopyrazolo[3,4-d]pyrimidine-based dual IGF1R/Src inhibitor as a novel anticancer agent with minimal toxicity. AB - BACKGROUND: Both the type I insulin-like growth factor receptor (IGF1R) and Src pathways are associated with the development and progression of numerous types of human cancer, and Src activation confers resistance to anti-IGF1R therapies. Hence, targeting both IGF1R and Src concurrently is one of the main challenges in combating resistance to the currently available anti-IGF1R-based anticancer therapies. However, the enhanced toxicity from this combinatorial treatment could be one of the main hurdles for this strategy, suggesting the necessity of developing a novel strategy for co-targeting IGF1R and Src to meet an urgent clinical need. METHODS: We synthesized a series of 4-aminopyrazolo[3,4 d]pyrimidine-based dual IGF1R/Src inhibitors, selected LL28 as an active compound and evaluated its potential antitumor effects in vitro and in vivo using the MTT assay, colony formation assays, flow cytometric analysis, a tumor xenograft model, and the Kras G12D/+ -driven spontaneous lung tumorigenesis model. RESULTS: LL28 markedly suppressed the activation of IGF1R and Src and significantly inhibited the viability of several NSCLC cell lines in vitro by inducing apoptosis. Administration of mice with LL28 significantly suppressed the growth of H1299 NSCLC xenograft tumors without overt toxicity and substantially reduced the multiplicity, volume, and load of lung tumors in the Kras G12D/+ -driven lung tumorigenesis model. CONCLUSIONS: The present results suggest the potential of LL28 as a novel anticancer drug candidate targeting both IGF1R and Src, providing a new avenue to efficient anticancer therapies. Further investigation is warranted in advanced preclinical and clinical settings. PMID- 29455662 TI - The role of RICTOR downstream of receptor tyrosine kinase in cancers. AB - The importance of the network defined by phosphatidylinositol-3-kinase (PI3K), AKT and mammalian target of rapamycin (mTOR) downstream of Receptor Tyrosine Kinase (RTK) has been known for many years but the central role of RICTOR (rapamycin-insensitive companion of mTOR) in this pathway is only starting to emerge. RICTOR is critical for mTORC2 (the mammalian target of rapamycin complex 2) kinase activity and as such plays a key role downstream of RTK. Alterations of RICTOR have been identified in a number of cancer cell types and its involvement in tumorigenesis has begun to be unraveled recently. Here, we summarize new research into the biology of RICTOR signaling in cancers focusing on tumors with altered RTK. We show that, as a key signaling node and critical effector of RTKs, RICTOR is becoming a valuable therapeutic target in cancer with altered RTK. PMID- 29455663 TI - Targeting tumour microenvironment by tyrosine kinase inhibitor. AB - Tumour microenvironment (TME) is a key determinant of tumour growth and metastasis. TME could be very different for each type and location of tumour and TME may change constantly during tumour growth. Multiple counterparts in surrounding microenvironment including mesenchymal-, hematopoietic-originated cells as well as non-cellular components affect TME. Thus, therapeutics that can disrupt the tumour-favouring microenvironment should be further explored for cancer therapy. Previous efforts in unravelling the dysregulated mechanisms of TME components has identified numerous protein tyrosine kinases, while its corresponding inhibitors have demonstrated potent modulatory effect on TME. Recent works have demonstrated that beyond the direct action on cancer cells, tyrosine kinase inhibitors (TKIs) have been implicated in inactivation or normalization of dysregulated TME components leading to cancer regression. Either through re-sensitizing the tumour cells or reversing the immunological tolerance microenvironment, the emergence of these TME modulatory mechanism of TKIs supports the combinatory use of TKIs with current chemotherapy or immunotherapy for cancer therapy. Therefore, an appropriate understanding on TME modulation by TKIs may offer another mode of action of TKIs for cancer treatment. This review highlights mode of kinase activation or paracrine ligand production from TME components and summarises the findings on the potential use of various TKIs on regulating TME components. At last, the combination use of current TKIs with immunotherapy in the perspectives of efficacy and safety are discussed. PMID- 29455664 TI - Advances in studies of tyrosine kinase inhibitors and their acquired resistance. AB - Protein tyrosine kinase (PTK) is one of the major signaling enzymes in the process of cell signal transduction, which catalyzes the transfer of ATP-gamma phosphate to the tyrosine residues of the substrate protein, making it phosphorylation, regulating cell growth, differentiation, death and a series of physiological and biochemical processes. Abnormal expression of PTK usually leads to cell proliferation disorders, and is closely related to tumor invasion, metastasis and tumor angiogenesis. At present, a variety of PTKs have been used as targets in the screening of anti-tumor drugs. Tyrosine kinase inhibitors (TKIs) compete with ATP for the ATP binding site of PTK and reduce tyrosine kinase phosphorylation, thereby inhibiting cancer cell proliferation. TKI has made great progress in the treatment of cancer, but the attendant acquired acquired resistance is still inevitable, restricting the treatment of cancer. In this paper, we summarize the role of PTK in cancer, TKI treatment of tumor pathways and TKI acquired resistance mechanisms, which provide some reference for further research on TKI treatment of tumors. PMID- 29455665 TI - PTEN/PTENP1: 'Regulating the regulator of RTK-dependent PI3K/Akt signalling', new targets for cancer therapy. AB - Regulation of the PI-3 kinase (PI3K)/Akt signalling pathway is essential for maintaining the integrity of fundamental cellular processes, cell growth, survival, death and metabolism, and dysregulation of this pathway is implicated in the development and progression of cancers. Receptor tyrosine kinases (RTKs) are major upstream regulators of PI3K/Akt signalling. The phosphatase and tensin homologue (PTEN), a well characterised tumour suppressor, is a prime antagonist of PI3K and therefore a negative regulator of this pathway. Loss or inactivation of PTEN, which occurs in many tumour types, leads to overactivation of RTK/PI3K/Akt signalling driving tumourigenesis. Cellular PTEN levels are tightly regulated by a number of transcriptional, post-transcriptional and post translational regulatory mechanisms. Of particular interest, transcription of the PTEN pseudogene, PTENP1, produces sense and antisense transcripts that exhibit post-transcriptional and transcriptional modulation of PTEN expression respectively. These additional levels of regulatory complexity governing PTEN expression add to the overall intricacies of the regulation of RTK/PI-3 K/Akt signalling. This review will discuss the regulation of oncogenic PI3K signalling by PTEN (the regulator) with a focus on the modulatory effects of the sense and antisense transcripts of PTENP1 on PTEN expression, and will further explore the potential for new therapeutic opportunities in cancer treatment. PMID- 29455666 TI - KRAS oncogene in non-small cell lung cancer: clinical perspectives on the treatment of an old target. AB - Lung neoplasms are the leading cause of death by cancer worldwide. Non-small cell lung cancer (NSCLC) constitutes more than 80% of all lung malignancies and the majority of patients present advanced disease at onset. However, in the last decade, multiple oncogenic driver alterations have been discovered and each of them represents a potential therapeutic target. Although KRAS mutations are the most frequently oncogene aberrations in lung adenocarcinoma patients, effective therapies targeting KRAS have yet to be developed. Moreover, the role of KRAS oncogene in NSCLC remains unclear and its predictive and prognostic impact remains controversial. The study of the underlying biology of KRAS in NSCLC patients could help to determine potential candidates to evaluate novel targeted agents and combinations that may allow a tailored treatment for these patients. The aim of this review is to update the current knowledge about KRAS-mutated lung adenocarcinoma, including a historical overview, the biology of the molecular pathways involved, the clinical relevance of KRAS mutations as a prognostic and predictive marker and the potential therapeutic approaches for a personalized treatment of KRAS-mutated NSCLC patients. PMID- 29455668 TI - Function of the c-Met receptor tyrosine kinase in carcinogenesis and associated therapeutic opportunities. AB - c-Met is a receptor tyrosine kinase belonging to the MET (MNNG HOS transforming gene) family, and is expressed on the surfaces of various cells. Hepatocyte growth factor (HGF) is the ligand for this receptor. The binding of HGF to c-Met initiates a series of intracellular signals that mediate embryogenesis and wound healing in normal cells. However, in cancer cells, aberrant HGF/c-Met axis activation, which is closely related to c-Met gene mutations, overexpression, and amplification, promotes tumor development and progression by stimulating the PI3K/AKT, Ras/MAPK, JAK/STAT, SRC, Wnt/beta-catenin, and other signaling pathways. Thus, c-Met and its associated signaling pathways are clinically important therapeutic targets. In this review, we elaborate on the molecular structure of c-Met and HGF and the mechanism through which their interaction activates the PI3K/AKT, Ras/MAPK, and Wnt signaling pathways. We also summarize the connection between c-Met and RON and EGFR, which are also receptor tyrosine kinases. Finally, we introduce the current therapeutic drugs that target c-Met in primary tumors, and their use in clinical research. PMID- 29455667 TI - Role of Non Receptor Tyrosine Kinases in Hematological Malignances and its Targeting by Natural Products. AB - Tyrosine kinases belong to a family of enzymes that mediate the movement of the phosphate group to tyrosine residues of target protein, thus transmitting signals from the cell surface to cytoplasmic proteins and the nucleus to regulate physiological processes. Non-receptor tyrosine kinases (NRTK) are a sub-group of tyrosine kinases, which can relay intracellular signals originating from extracellular receptor. NRTKs can regulate a huge array of cellular functions such as cell survival, division/propagation and adhesion, gene expression, immune response, etc. NRTKs exhibit considerable variability in their structural make up, having a shared kinase domain and commonly possessing many other domains such as SH2, SH3 which are protein-protein interacting domains. Recent studies show that NRTKs are mutated in several hematological malignancies, including lymphomas, leukemias and myelomas, leading to aberrant activation. It can be due to point mutations which are intragenic changes or by fusion of genes leading to chromosome translocation. Mutations that lead to constitutive kinase activity result in the formation of oncogenes, such as Abl, Fes, Src, etc. Therefore, specific kinase inhibitors have been sought after to target mutated kinases. A number of compounds have since been discovered, which have shown to inhibit the activity of NRTKs, which are remarkably well tolerated. This review covers the role of various NRTKs in the development of hematological cancers, including their deregulation, genetic alterations, aberrant activation and associated mutations. In addition, it also looks at the recent advances in the development of novel natural compounds that can target NRTKs and perhaps in combination with other forms of therapy can show great promise for the treatment of hematological malignancies. PMID- 29455669 TI - EGFR-TKIs resistance via EGFR-independent signaling pathways. AB - Tyrosine kinase inhibitors (TKIs)-treatments bring significant benefit for patients harboring epidermal growth factor receptor (EGFR) mutations, especially for those with lung cancer. Unfortunately, the majority of these patients ultimately develop to the acquired resistance after a period of treatment. Two central mechanisms are involved in the resistant process: EGFR secondary mutations and bypass signaling activations. In an EGFR-dependent manner, acquired mutations, such as T790 M, interferes the interaction between TKIs and the kinase domain of EGFR. While in an EGFR-independent manner, dysregulation of other receptor tyrosine kinases (RTKs) or abnormal activation of downstream compounds both have compensatory functions against the inhibition of EGFR through triggering phosphatidylinositol 3-kinase (PI3K)/Akt and mitogen-activated protein kinase (MAPK) signaling axes. Nowadays, many clinical trials aiming to overcome and prevent TKIs resistance in various cancers are ongoing or completed. EGFR TKIs in accompany with the targeted agents for resistance-related factors afford a promising first-line strategy to further clinical application. PMID- 29455670 TI - The rationale for druggability of CCDC6-tyrosine kinase fusions in lung cancer. AB - Gene fusions occur in up to 17% of solid tumours. Oncogenic kinases are often involved in such fusions. In lung cancer, almost 30% of patients carrying an activated oncogene show the fusion of a tyrosine kinase to an heterologous gene. Several genes are partner in the fusion with the three kinases ALK, ROS1 and RET in lung. The impaired function of the partner gene, in combination with the activation of the kinase, may alter the cell signaling and promote the cancer cell addiction to the oncogene. Moreover, the gene that is partner in the fusion to the kinase may affect the response to therapeutics and/or promote resistance in the cancer cells. Few genes are recurrent partners in tyrosine kinase fusions in lung cancer, including CCDC6, a recurrent partner in ROS1 and RET fusions, that can be selected as possible target for new strategies of combined therapy including TKi. PMID- 29455671 TI - Oncogenic fusion proteins adopt the insulin-like growth factor signaling pathway. AB - The insulin-like growth factor-1 receptor (IGF1R) has been identified as a potent anti-apoptotic, pro-survival tyrosine kinase-containing receptor. Overexpression of the IGF1R gene constitutes a typical feature of most human cancers. Consistent with these biological roles, cells expressing high levels of IGF1R are expected not to die, a quintessential feature of cancer cells. Tumor specific chromosomal translocations that disrupt the architecture of transcription factors are a common theme in carcinogenesis. Increasing evidence gathered over the past fifteen years demonstrate that this type of genomic rearrangements is common not only among pediatric and hematological malignancies, as classically thought, but may also provide a molecular and cytogenetic foundation for an ever-increasing portion of adult epithelial tumors. In this review article we provide evidence that the mechanism of action of oncogenic fusion proteins associated with both pediatric and adult malignancies involves transactivation of the IGF1R gene, with ensuing increases in IGF1R levels and ligand-mediated receptor phosphorylation. Disrupted transcription factors adopt the IGF1R signaling pathway and elicit their oncogenic activities via activation of this critical regulatory network. Combined targeting of oncogenic fusion proteins along with the IGF1R may constitute a promising therapeutic approach. PMID- 29455672 TI - Non ABL-directed inhibitors as alternative treatment strategies for chronic myeloid leukemia. AB - The introduction of ABL Tyrosine Kinase Inhibitors (TKIs) has significantly improved the outcome of Chronic Myeloid Leukemia (CML) patients that, in large part, achieve satisfactory hematological, cytogenetic and molecular remissions. However, approximately 15-20% fail to obtain optimal responses according to the current European Leukemia Network recommendation because of drug intolerance or resistance.Moreover, a plethora of evidence suggests that Leukemic Stem Cells (LSCs) show BCR-ABL1-independent survival. Hence, they are unresponsive to TKIs, leading to disease relapse if pharmacological treatment is discontinued.All together, these biological events generate a subpopulation of CML patients in need of alternative therapeutic strategies to overcome TKI resistance or to eradicate LSCs in order to allow cure of the disease.In this review we update the role of "non ABL-directed inhibitors" targeting signaling pathways downstream of the BCR-ABL1 oncoprotein and describe immunological approaches activating specific T cell responses against CML cells. PMID- 29455674 TI - Aggressive fibromatosis in the infratemporal fossa presenting as trismus: a case report. AB - BACKGROUND: Here we report a very rare entity of an infratemporal region aggressive fibromatosis in a 23-year-old Tharu man who had presented with the symptoms of painless but progressive trismus. CASE PRESENTATION: We describe a case of aggressive fibromatosis in a 23-year-old Tharu man. Radiological imaging as well as an immunohistochemistry panel from a biopsy indicated a diagnosis of an aggressive fibromatosis. Since there was no aggravation in his trismus following surgery and because of his poor socioeconomic status, he was advised to attend regular follow-up visits without any adjuvant therapy. CONCLUSIONS: This case report adds to the notion of keeping the differential diagnosis of an aggressive fibromatosis in all patients presenting with progressive but painless trismus. The characteristic imaging findings as well an immunohistochemistry panel will help us clinch the correct diagnosis. PMID- 29455676 TI - Evaluation of an Ophthalmoscopy Simulator to Teach Funduscopy Skills to Pediatric Residents. AB - BACKGROUND: Medical school and residency training in ophthalmoscopic evaluation is limited, reducing diagnostic accuracy. We sought to evaluate the efficacy of self-study using an ophthalmoscopy simulator to improve the technical motor skills involved in direct funduscopy in postgraduate pediatric residents. METHODS: In this randomized-controlled study, 17 pediatric residents (postgraduate years 1-3) were randomized to control (n=8) or intervention (n=9) groups. Participants were asked to correctly identify the funduscopic findings presented to them on an ophthalmoscopy simulator after being trained on its use. Each participant was asked to review 20 images of the fundus, and then record their multiple-choice response on a scantron sheet listing all possible funduscopic pathologies. Pre- and post-intervention testing was performed. Survey data assessing exposure to funduscopy skills during undergraduate and postgraduate training and overall experience with the simulator were collected. RESULTS: Most (65% [11/17]) participants reported minimal or no formal teaching in ophthalmology during their undergraduate medical studies. Average pre intervention score (of 20) was 10.24+/-1.75 (51%) for the entire group, with no statistically significant difference between average pre-score in the control (10.63+/-1.77) versus intervention (9.89+/-1.76, p=0.405) groups. Intervention subjects experienced a statistically significant improvement in scores (9.89+/ 1.76 vs. 12.78+/-2.05, p=0.006 [95% confidence interval 4.80-0.98]), but control subjects did not. CONCLUSIONS: A single session with an ophthalmoscopy simulator can improve diagnostic accuracy in postgraduate pediatric trainees. Use of ophthalmoscopy simulation represents a novel addition to traditional learning methods for postgraduate pediatric residents that can help trainees to improve their confidence and accuracy in performing this challenging examination. PMID- 29455678 TI - Cryptic species and their utilization of indigenous and non-indigenous intermediate hosts in the acanthocephalan Polymorphus minutus sensu lato (Polymorphidae). AB - The bird-infecting acanthocephalan Polymorphus minutus has been suggested to comprise different lineages or even cryptic species using different intermediate hosts. To clarify this open question, we investigated Polymorphus cf. minutus cystacanths originating from amphipod intermediate hosts from 27 sites in Germany and France. Parasites and hosts were identified using integrated datasets (COI and/or morphology for hosts and COI + ITS1-5.8S-ITS2 for parasites).Mitochondrial and nuclear data (ITS1) strongly support the existence of three cryptic species in Polymorphus cf. minutus (type 1-3). These three types reveal a high degree of intermediate host specificity, with Polymorphus type 1 only encountered in Gammarus fossarum type B, Polymorphus type 2 in Echinogammarus sp. and Echinogammarus berilloni, and Polymorphus type 3 in Gammarus pulex and Gammarus roeselii. Our results point to a so far neglected cryptic diversity of the genus Polymorphus in Central Europe. Furthermore, Polymorphus type 2 is most likely a non-native parasite in Germany that co-invaded with E. berilloni from the Mediterranean area. Potentially, type 3 originates from South-East Europe and migrated to Germany by G. roeselii, where it might have captured G. pulex as an intermediate host. Therefore, our findings can be seen in the context of ecological globalization in terms of the anthropogenic displacement of intermediate hosts and its impact on the genetic divergence of the parasites. PMID- 29455675 TI - The function and therapeutic targeting of anaplastic lymphoma kinase (ALK) in non small cell lung cancer (NSCLC). AB - Lung cancer is the leading cause of death by cancer in North America. A decade ago, genomic rearrangements in the anaplastic lymphoma kinase (ALK) receptor tyrosine kinase were identified in a subset of non-small cell lung carcinoma (NSCLC) patients. Soon after, crizotinib, a small molecule ATP-competitive ALK inhibitor was proven to be more effective than chemotherapy in ALK-positive NSCLC patients. Crizotinib and two other ATP-competitive ALK inhibitors, ceritinib and alectinib, are approved for use as a first-line therapy in these patients, where ALK rearrangement is currently diagnosed by immunohistochemistry and in situ hybridization. The clinical success of these three ALK inhibitors has led to the development of next-generation ALK inhibitors with even greater potency and selectivity. However, patients inevitably develop resistance to ALK inhibitors leading to tumor relapse that commonly manifests in the form of brain metastasis. Several new approaches aim to overcome the various mechanisms of resistance that develop in ALK-positive NSCLC including the knowledge-based alternate and successive use of different ALK inhibitors, as well as combined therapies targeting ALK plus alternative signaling pathways. Key issues to resolve for the optimal implementation of established and emerging treatment modalities for ALK rearranged NSCLC therapy include the high cost of the targeted inhibitors and the potential of exacerbated toxicities with combination therapies. PMID- 29455677 TI - The gene-environmental architecture of the development of adolescent substance use. AB - BACKGROUND: Using a longitudinal twin design and a latent growth curve/autoregressive approach, this study examined the genetic-environmental architecture of substance use across adolescence. METHODS: Self-reports of substance use (i.e. alcohol, marijuana) were collected at ages 13, 14, 15, and 17 years from 476 twin pairs (475 boys, 477 girls) living in the Province of Quebec, Canada. Substance use increased linearly across the adolescent years. RESULTS: ACE modeling revealed that genetic, as well as shared and non-shared environmental factors explained the overall level of substance use and that these same factors also partly accounted for growth in substance use from age 13 to 17. Additional genetic factors predicted the growth in substance use. Finally, autoregressive effects revealed age-specific non-shared environmental influences and, to a lesser degree, age-specific genetic influences, which together accounted for the stability of substance use across adolescence. CONCLUSIONS: The results support and expand the notion that genetic and environmental influences on substance use during adolescence are both developmentally stable and developmentally dynamic. PMID- 29455679 TI - Nutrient profiling and adherence to components of the UK national dietary guidelines association with metabolic risk factors for CVD and diabetes: Airwave Health Monitoring Study. AB - CVD is the leading cause of death worldwide. Diet is a key modifiable component in the development of CVD. No official UK diet quality index exists for use in UK nutritional epidemiological studies. The aims of this study are to: (i) develop a diet quality index based on components of UK dietary reference values (DRV) and (ii) determine the association between the index, the existing UK nutrient profile (NP) model and a comprehensive range of cardiometabolic risk markers among a British adult population. A cross-sectional analysis was conducted using data from the Airwave Health Monitoring Study (n 5848). Dietary intake was measured by 7-d food diary and metabolic risk using waist circumference, BMI, blood lipid profile, glycated Hb (HbA1c) and blood pressure measurements. Diet quality was assessed using the novel DRV index and NP model. Associations between diet and cardiometabolic risk were analysed via multivariate linear models and logistic regression. A two-point increase in NP score was associated with total cholesterol (beta -0.33 mmol/l, P<0.0001) and HbA1c (beta -0.01 %, P<0.0001). A two-point increase in DRV score was associated with waist circumference (beta 0.56 cm, P<0.0001), BMI (beta -0.15 kg/m2, P<0.0001), total cholesterol (beta 0.06 mmol/l, P<0.0001) and HbA1c (beta -0.02 %, P=0.002). A one-point increase in DRV score was associated with type 2 diabetes (T2D) (OR 0.94, P=0.01) and obesity (OR 0.95, P<0.0001). The DRV index is associated with overall diet quality and risk factors for CVD and T2D, supporting its application in nutritional epidemiological studies investigating CVD risk in a UK population.

AB - : Introduction Many Syrians have left their country and migrated to other countries since March 2011, due to the civil war. As of March 2016, a total of 2,747,946 Syrian refugees had immigrated to Turkey. Some Syrian refugees have been living in camps, while 2,475,134 have been living in metropolitan areas, such as Ankara. Study Objective This study investigated Emergency Medical Service (EMS) utilization among Syrian refugees residing in Ankara. METHODS: This study was a descriptive, cross-sectional database analysis using data obtained from the Department of EMS of the Ankara Provincial Health Directorate. CONCLUSION: Five stations in the Altindag region of Ankara responded to 42% of all calls from Syrian refugees. Prehospital EMS in Ankara have been used mostly by Syrian refugees younger than 18-years-old. Study findings also suggest that medical staff in regions where Syrian refugees are likely to be treated should be supported and provided with the ability to overcome language barriers and cultural differences.

PMID- 29455681 TI - Human dendritic cell sequestration onto the Necator americanus larval sheath during ex-sheathing: a possible mechanism for immune privilege. AB - Despite the profound health implications of Necator americanus infection in humans, many aspects of its interaction with the host immune system are poorly understood. Here we investigated the early events at the interface of N. americanus larvae (L3) and human dendritic cells (DCs). Our data show that co culturing DCs and the larvae trigger ex-sheathing of hookworms rapidly where a majority of DCs are sequestered onto the larval sheath allowing the ex-sheathed larvae to migrate away unchallenged. Intriguingly, DCs show negligible interaction with the ex-sheathed larvae, alluding to differences between the surface chemistry of the larva and its sheath. Furthermore, blocking of two key C type lectin receptors on DC surface (i.e. DC-SIGN and mannose receptor) resulted in inhibition of ex-sheathing process and DC sequestration, highlighting the importance of C-type lectins on DCs in the induction of the ex-sheathing. Analyses of DC phenotype and cytokine profile after co-culture with the N. americanus larvae showed an immature phenotype as evidenced by the low expression of the maturation markers and cytokines. These data provide new insights into early events at the interface of human DCs and N. americanus larvae and could explain how L3 evade immune recognition upon initial interaction with DCs. PMID- 29455682 TI - Characterization of Interventional Studies of the Cholera Epidemic in Haiti. AB - In October 2010, the Haitian Ministry of Public Health and Population (MSPP; Port au Prince, Haiti) reported a cholera epidemic caused by contamination of the Artibonite River by a United Nation Stabilization Mission camp. Interventional studies of the subsequent responses, including a descriptive Methods section and systematic approach, may be useful in facilitating comparisons and applying lessons learned to future outbreaks. The purpose of this study was to examine publicly available documents relating to the 2010 cholera outbreak to answer: (1) What information is publicly available on interventional studies conducted during the epidemic, and what was/were the impact(s)? and (2) Can the interventions be compared, and what lessons can be learned from their comparison? A PubMed (National Center for Biotechnology Information, National Institutes of Health; Bethesda, Maryland USA) search was conducted using the parameters "Haiti" and "cholera." Studies were categorized as "interventional research," "epidemiological research," or "other." A distinction was made between studies and narrative reports. The PubMed search yielded 171 papers, 59 (34.0%) of which were epidemiological and 12 (7.0%) were interventional studies. The remaining 100 papers (59.0%) comprised largely of narrative, anecdotal descriptions. An expanded examination of publications by the World Health Organization (WHO; Geneva, Switzerland), the Center for Research in the Epidemiology of Disasters (CRED; Brussels, Belgium), United States Agency for International Development (USAID; Washington, DC USA)-Development Experience Clearinghouse (DEC), and US National Library of Medicine's (NLM; Bethesda, Maryland USA) Disaster Literature databases yielded no additional interventional studies. The unstructured formats and differing levels of detail prohibited comparisons between interventions, even between those with a similar approach. Only two (17.0%) interventional studies included any impact data, although neither commented whether the intervention improved health or reduced incidence or mortality related to cholera. Agreed frameworks for guiding responses and subsequent reporting are needed to ensure reports contain sufficient detail to draw conclusions for the definition of best practices and for the design of future interventions.

PMID- 29455673 TI - Kinase-targeted cancer therapies: progress, challenges and future directions. AB - The human genome encodes 538 protein kinases that transfer a gamma-phosphate group from ATP to serine, threonine, or tyrosine residues. Many of these kinases are associated with human cancer initiation and progression. The recent development of small-molecule kinase inhibitors for the treatment of diverse types of cancer has proven successful in clinical therapy. Significantly, protein kinases are the second most targeted group of drug targets, after the G-protein coupled receptors. Since the development of the first protein kinase inhibitor, in the early 1980s, 37 kinase inhibitors have received FDA approval for treatment of malignancies such as breast and lung cancer. Furthermore, about 150 kinase targeted drugs are in clinical phase trials, and many kinase-specific inhibitors are in the preclinical stage of drug development. Nevertheless, many factors confound the clinical efficacy of these molecules. Specific tumor genetics, tumor microenvironment, drug resistance, and pharmacogenomics determine how useful a compound will be in the treatment of a given cancer. This review provides an overview of kinase-targeted drug discovery and development in relation to oncology and highlights the challenges and future potential for kinase-targeted cancer therapies.

AB - OBJECTIVES: Economic decision-support tools can provide valuable information for tobacco control stakeholders, but their usability may impact the adoption of such tools. This study aims to illustrate a mixed-method usability evaluation of an economic decision-support tool for tobacco control, using the EQUIPT ROI tool prototype as a case study. METHODS: A cross-sectional mixed methods design was used, including a heuristic evaluation, a thinking aloud approach, and a questionnaire testing and exploring the usability of the Return of Investment tool. RESULTS: A total of sixty-six users evaluated the tool (thinking aloud) and completed the questionnaire. For the heuristic evaluation, four experts evaluated the interface. In total twenty-one percent of the respondents perceived good usability. A total of 118 usability problems were identified, from which twenty six problems were categorized as most severe, indicating high priority to fix them before implementation. CONCLUSIONS: Combining user-based and expert-based evaluation methods is recommended as these were shown to identify unique usability problems. The evaluation provides input to optimize usability of a decision-support tool, and may serve as a vantage point for other developers to conduct usability evaluations to refine similar tools before wide-scale implementation. Such studies could reduce implementation gaps by optimizing usability, enhancing in turn the research impact of such interventions. PMID- 29455685 TI - HEALTH TECHNOLOGY ASSESSMENT EVIDENCE ON E-HEALTH/M-HEALTH TECHNOLOGIES: EVALUATING THE TRANSPARENCY AND THOROUGHNESS. AB - OBJECTIVES: Evaluation is crucial for integration of e-Health/m-Health into healthcare systems and health technology assessment (HTA) could offer sound methodological basis for these evaluations. Aim of this study was to look for HTA reports on e-Health/m-Health technologies and to analyze their transparency, consistency and thoroughness, with the goal to detect areas that need improvement. METHODS: PubMed, ISI-WOS, and University of York - Centre for Reviews and Dissemination-electronic databases were searched to identify reports on e-Health/m-Health technologies, published up until April 1, 2016. The International Network of Agencies for Health Technology Assessment (INAHTA) checklist was used to evaluate transparency and consistency of included reports. Thoroughness was assessed by checking the presence of domains suggested by the European network for Health Technology Assessment (EUnetHTA) HTA Core Model. RESULTS: Twenty-eight reports published between 1999 and 2015 were included. Most were delivered by non-European countries (71.4 percent) and only 35.7 percent were classified as full reports. All the HTA reports defined the scope of research whereas more than 80 percent provided author details, summary, discussed findings, and conclusion. On the contrary, policy and research questions were clearly defined in around 30 percent and 50 percent of reports. With respect to the EUnetHTA Core Model, around 70 percent of reports dealt with effectiveness and economic evaluation, more than 50 percent described health problem and approximately 40 percent organizational and social aspects. CONCLUSIONS: E Health/m-Health technologies are increasingly present in the field of HTA. Yet, our review identified several missing elements. Most of the reports failed to respond to relevant assessment components, especially ethical, social and organizational implications. PMID- 29455686 TI - COST-UTILITY ANALYSIS OF PRIVATE CONTRACTING TO REDUCE PUBLIC WAITING TIMES FOR JOINT REPLACEMENT SURGERY. AB - OBJECTIVES: Earlier treatment of publicly funded patients may achieve health gains that justify the additional costs of reducing waiting times. This study reports on the cost-effectiveness of implementing a private contracting model to meet alternative maximum waiting time targets for publicly funded patients undergoing total knee replacement surgery in Australia. METHODS: A linked decision tree and cohort Markov model was developed and populated and validated using secondary data sources to represent the pathways, costs, and quality adjusted life-years (QALYs) gained of non-urgent patients with alternative waiting times for total knee replacement surgery to a maximum age of 100 years. RESULTS: Assuming public waiting times are reduced through the purchase of private services, additional QALYs are gained at an incremental cost of less than $40,000. Value could be increased if lower private prices could be negotiated. Results are also sensitive to the rate of deterioration in function while waiting for surgery and the impact of functional status at the time of surgery on postsurgery outcomes. CONCLUSIONS: More evidence on the value of expanded capacity or new models of care may inform new funding models to support such investments and reduced prices for new technologies, leading to more efficient and sustainable publicly funded healthcare systems. PMID- 29455687 TI - Distinct risk factors for obsessive and compulsive symptoms in chronic schizophrenia. AB - BACKGROUND: Obsessive-compulsive disorder (OCD) is common in clozapine-treated patients although the actual prevalence, phenomenology and risk factors remain unclear. The aim of the present study was to address the three aforementioned questions. METHODS: The electronic records of a large cohort of clozapine medicated schizophrenia patients routinely screened for OCD were used. The Obsessive Compulsive Inventory Revised version (OCI-R) was available from 118 cases and a 21 points cut-off threshold for OCD was defined. RESULTS: OCD prevalence was 47%, higher in patients on poly-pharmacy than on monotherapy (64% vs 31%; p = 0.001). Two OCI-R factors had significantly higher scores and distinct risk factors: checking behaviour (mean = 5.1; SD = 3.6) correlated with length of clozapine treatment (r = 0.21; p = 0.026), and obsessing factor (mean = 4.8; SD = 3.6) correlated with psychosis severity (r = 0.59; p = 0.001). These factors along with total OCI-R, did not correlate with either clozapine dose or plasma levels, after correcting for psychosis severity. CONCLUSIONS: Screening for OCD in clozapine patients, and probably in those treated with structurally similar drugs with potent antiserotoninergic properties, should be widely adopted by clinicians. Further research is needed to understand the pathophysiology underlying repetitive behavior onset in clozapine-treated patients. PMID- 29455688 TI - Early-life nutritional status and metabolic syndrome: gender-specific associations from a cross-sectional analysis of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). AB - OBJECTIVE: In the present study we investigated gender-specific associations of low birth weight (LBW) and shorter relative leg length with metabolic syndrome (MetS) after adjusting for sociodemographic characteristics and health-related behaviours. We also investigated whether these associations are independent of age at menarche and BMI at 20 years old. DESIGN: Cross-sectional analysis. SUBJECTS: Baseline data from 12 602 participants (35-74 years) of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), 2008-2010. SETTING: MetS was defined according to the revised National Cholesterol Education Program Adult Treatment Panel III guidelines. LBW (<2.5 kg) and age- and sex-standardized relative leg length (high, medium and low) were the explanatory variables studied. The strength of the associations between the explanatory variables and MetS was estimated by Poisson regression with robust variance. RESULTS: MetS prevalence was 34.2 %; it was more prevalent in men (36.8 %) than in women (32.2 %). In multivariate analysis, LBW was associated (prevalence ratio; 95 % CI) with MetS only in women (1.28; 1.24, 1.45). Shorter leg length was associated with MetS in both men (1.21; 1.09, 1.35 and 1.46; 1.29, 1.65 for low and medium lengths, respectively) and women (1.12; 1.00, 1.25 and 1.40; 1.22, 1.59 for low and medium lengths, respectively). Additional adjustments for age at menarche and BMI at 20 years old did not change the associations. CONCLUSIONS: Poor nutritional status as estimated by LBW and lower leg length in childhood was associated with a higher prevalence of MetS, although LBW was a significant factor only among women. PMID- 29455689 TI - INDUSTRY'S EXPERIENCES WITH THE SCIENTIFIC ADVICE OFFERED BY THE FEDERAL JOINT COMMITTEE WITHIN THE EARLY BENEFIT ASSESSMENT OF PHARMACEUTICALS IN GERMANY. AB - OBJECTIVES: Optional scientific advice (SA) for the early benefit assessment of pharmaceuticals is offered by the German decision maker, the Federal Joint Committee (FJC). The aim of this study was to elicit manufacturers' experiences with the SA procedures offered by the FJC to date. METHODS: A preliminary survey on a small sample size was conducted. Subsequently, a questionnaire comprising eight items, which was developed on the basis of that survey, was used. Data were analyzed using qualitative and quantitative approaches. RESULTS: The elicitation, including a sample of 25 percent of the completed advice, highlighted the following, regarding the process as well as to the content shortcomings of the SA procedures from an industrial perspective: inconsistencies, FJC's lack of expertise in conducting clinical trials, partially incomplete answers. and a low willingness of the FJC to engage in dialogue with industry were criticized. On the other hand, the majority of respondents expressed a positive attitude concerning unambiguousness, completeness, traceability, discussion atmosphere, and the protocol of the advice. Early SA, before pivotal trials start, showed a significantly higher completeness compared with late SA with respect to endpoints and study duration. Within 4 years the quality of FJC's propositions on some topics improved significantly. CONCLUSIONS: Only a few statistically significant differences were detectable between early versus late SA. A positive trend in industry's perception of the SA can be observed over time. A more active involvement of additional stakeholders and the incorporation of procedural elements from other healthcare systems could improve the quality of the SA offered by the FJC. PMID- 29455690 TI - Effect of Cerebral Perfusion Pressure on Acute Respiratory Distress Syndrome. AB - BACKGROUND: Increased cerebral perfusion pressure (CPP)>70 mmHg has been associated with acute respiratory distress syndrome (ARDS) after traumatic brain injury (TBI). Since this reported association, significant changes in ventilation strategies and fluid management have been accepted as routine critical care. Recently, individualized perfusion targets using autoregulation monitoring suggest CPP titration>70 mmHg. Given these clinical advances, the association between ARDS and increased CPP requires further delineation. OBJECTIVE: To determine the association between ARDS and increased CPP after TBI. METHODS: We conducted a single-center historical cohort study investigating the association of increased CPP and ARDS after TBI. We collected demographic data and physiologic data for CPP, intracranial pressure, mechanical ventilation, cumulative fluid balance and delta/driving pressure (DeltaP). We collected outcomes measures pertaining to duration of ventilation, intensive care unit admission length, hospitalization length and 6-month neurological outcome. RESULTS: In total, 113 patients with severe TBI and multimodal neuromonitoring were included. In total, 16 patients (14%) developed ARDS according to the Berlin definition. There was no difference in the mean CPP during the first 7 days of admission between patients who developed ARDS (74 mmHg SD 18 vs. 73 mmHg SD 18, p=0.86) versus those who did not. Patients who developed ARDS had a higher DeltaP (15 mmHg [5] vs. 12 mmHg [4], p=0.016) and lower lung compliance (35 ml/cmH2O [10] vs. 49 ml/cmH2O [18], p=0.024) versus those who did not. CONCLUSION: We did not observe an association between increased CPP and ARDS. Patients with ARDS had higher DeltaP and lower lung compliance. PMID- 29455691 TI - A new species of Parapharyngodon Chatterji, 1933 (Oxyuroidea: Pharyngodonidae), parasitic in Osteocephalus taurinus (Anura: Hylidae) from Brazil. AB - Parapharyngodon politoedi n. sp. is described here, based on specimens found in the large intestines of Osteocephalus taurinus from the Caxiuana National Forest, State of Para, Brazil. The new species is assigned to Parapharyngodon based on the presence of non-embryonated eggs with sub-terminal opercula, when in the ovijector. Parapharyngodon politoedi belongs to a group of species with three pairs of cloacal papillae and differs from its congeners by morphometric aspects, such as the length of the spicule, and the combination of the following morphological characters: ovaries never encircling the oesophagus, tail shape in females, cloacal lips, sharply pointed spicule and presence of genital cone. This is the second species of nematode reported to parasitize O. taurinus and the eleventh species of Parapharyngodon from hylids in the Neotropical region. PMID- 29455692 TI - A non-invasive assessment of skin carotenoid status through reflection spectroscopy is a feasible, reliable and potentially valid measure of fruit and vegetable consumption in a diverse community sample. AB - OBJECTIVE: To assess the feasibility, reliability and validity of reflection spectroscopy (RS) to assess skin carotenoids in a racially diverse sample. DESIGN: Study 1 was a cross-sectional study of corner store customers (n 479) who completed the National Cancer Institute Fruit and Vegetable Screener as well as RS measures. Feasibility was assessed by examining the time it took to complete three RS measures, reliability was assessed by examining the variation between three RS measures, and validity was examined by correlation with self-reported fruit and vegetable consumption. In Study 2, validity was assessed in a smaller sample (n 30) by examining associations between RS measures and dietary carotenoids, fruits and vegetables as calculated from a validated FFQ and plasma carotenoids. SETTING: Eastern North Carolina, USA. RESULTS: It took on average 94.0 s to complete three RS readings per person. The average variation between three readings for each participant was 6.8 %. In Study 2, in models adjusted for age, race and sex, there were statistically significant associations between RS measures and (i) FFQ-estimated carotenoid intake (P<0.0001); (ii) FFQ-estimated fruit and vegetable consumption (P<0.010); and (iii) plasma carotenoids (P<0.0001). CONCLUSIONS: RS is a potentially improved method to approximate fruit and vegetable consumption among diverse participants. RS is portable and easy to use in field-based public health nutrition settings. More research is needed to investigate validity and sensitivity in diverse populations.

PMID- 29455694 TI - A Study of Hospital Disaster Preparedness in South Yemen. AB - : Introduction Despite emphasis by disaster experts on the importance of disaster preparedness, disaster management in Yemen has attracted only a little attention. Most of the efforts have focused on post-disaster relief activities rather than the pre-disaster preparedness and risk reduction. Hospitals have a crucial role in emergency response and should be prepared. Thus, the aim of this study was intended to assess the hospital preparedness of Aden Capital, South Yemen against disasters. METHOD: A cross-sectional study was conducted in June 2016. The sample was all Aden City facilities with a total number of 10 hospitals: five public and five private hospitals. A survey was done by using the World Health Organization (WHO; Geneva, Switzerland) standards checklist 2011. RESULTS: The overall preparedness of Aden City hospitals to disasters fell at the unacceptable level of readiness, with an average mean of 46.6 (SD = 38.31; range 24-82). Of 10 hospitals, two ranked insufficient while eight hospitals were at unacceptable levels of preparedness. CONCLUSION: All hospitals were noted grossly unprepared for potential disasters. Therefore, it is recommended that greater efforts be invested in creating a comprehensive strategy and national or local guidelines to establish an emergency management system based on the anticipated hazard and the needed resources.

AB - Mindfulness-based interventions (MBIs) have become widely used for common mental disorders (CMDs) but the state of the evidence has not been sufficiently investigated. The aims for this study were: (1) to quantify the effect size of MBIs for CMDs in the acute phase; (2) to explore moderator variables; and (3) to evaluate the evidence status of MBIs for the CMDs it has been tried for. A comprehensive systematic review and meta-analysis of randomized controlled trials (RCTs) were conducted. RCTs that evaluated MBI and included patients with a primary manifest CMD was included. Methodological quality, the risk of bias, publication bias and evidence status were assessed. Literature searches gave 2448 hits and 19 studies were included. MBIs were more effective than no treatment (g = 1.07) and treatment-as-usual (g = 0.40) but not in comparison to placebo (g = 0.17) or other active treatments (g = -0.01). Methodological quality was negatively correlated with outcome. For all psychiatric disorders it has been tested, MBIs were judged to have weak or no empirical support. The conclusion of the study is that the evidence-base for MBIs for CMDs in the acute phase is weak. PMID- 29455696 TI - Targeting habits in anorexia nervosa: a proof-of-concept randomized trial. AB - BACKGROUND: Habits are behavioral routines that are automatic and frequent, relatively independent of any desired outcome, and have potent antecedent cues. Among individuals with anorexia nervosa (AN), behaviors that promote the starved state appear habitual, and this is the foundation of a recent neurobiological model of AN. In this proof-of-concept study, we tested the habit model of AN by examining the impact of an intervention focused on antecedent cues for eating disorder routines. METHODS: The primary intervention target was habit strength; we also measured clinical impact via eating disorder psychopathology and actual eating. Twenty-two hospitalized patients with AN were randomly assigned to 12 sessions of either Supportive Psychotherapy or a behavioral intervention aimed at cues for maladaptive behavioral routines, Regulating Emotions and Changing Habits (REaCH). RESULTS: Covarying for baseline, REaCH was associated with a significantly lower Self-Report Habit Index (SRHI) score and significantly lower Eating Disorder Examination-Questionnaire (EDE-Q) global score at the end-of treatment. The end-of-treatment effect size for SRHI was d = 1.28, for EDE-Q was d = 0.81, and for caloric intake was d = 1.16. CONCLUSIONS: REaCH changed habit strength of maladaptive routines more than an active control therapy, and targeting habit strength yielded improvement in clinically meaningful measures. These findings support a habit-based model of AN, and suggest habit strength as a mechanism-based target for intervention. PMID- 29455697 TI - Meaningful Ways of Understanding and Measuring Change for People with Borderline Personality Disorder: A Thematic Analysis. AB - BACKGROUND: The effective treatment of Borderline Personality Disorder (BPD) presents healthcare providers with a significant challenge. The evidence base remains limited partially due to a lack of professional consensus and service user involvement regarding ways of measuring change. As a result, the limited evidence that is available draws on such a wide range of outcome measures, that comparison across treatment types is hindered, maintaining a lack of clarity regarding the clinical needs of this group. AIMS: This investigation aimed to follow the National Institute of Clinical Excellence (NICE, 2009) research recommendations by asking service users about meaningful change within their recovery. This forms a starting point for the future development of a tailored outcome measure. METHOD: Fifteen service users with a diagnosis of BPD participated in three focus groups across two specialist Personality Disorder services. The focus groups were analysed using Thematic Analysis. RESULTS: Two superordinate themes were synthesized from the data: (1) recovery to what?: 'How do you rewrite who you are?'; and (2) conditions for change. Each superordinate theme further consisted of three subordinate themes which elucidated the over arching themes. CONCLUSION: This investigation highlights the complex nature of measuring change in people who have received a BPD diagnosis. Further research is needed to develop meaningful ways of measuring change according to the needs and priorities of people with BPD. PMID- 29455698 TI - Stop the Bleed: The Effect of Hemorrhage Control Education on Laypersons' Willingness to Respond During a Traumatic Medical Emergency. AB - BACKGROUND: The "Stop the Bleed" campaign advocates for non-medical personnel to be trained in basic hemorrhage control. However, it is not clear what type of education or the duration of instruction needed to meet that requirement. The objective of this study was to determine the impact of a brief hemorrhage control educational curriculum on the willingness of laypersons to respond during a traumatic emergency. METHODS: This "Stop the Bleed" education initiative was conducted by the University of Texas Health San Antonio Office of the Medical Director (San Antonio, Texas USA) between September 2016 and March 2017. Individuals with formal medical certification were excluded from this analysis. Trainers used a pre-event questionnaire to assess participants knowledge and attitudes about tourniquets and responding to traumatic emergencies. Each training course included an individual evaluation of tourniquet placement, 20 minutes of didactic instruction on hemorrhage control techniques, and hands-on instruction with tourniquet application on both adult and child mannequins. The primary outcome in this study was the willingness to use a tourniquet in response to a traumatic medical emergency. RESULTS: Of 236 participants, 218 met the eligibility criteria. When initially asked if they would use a tourniquet in real life, 64.2% (140/218) responded "Yes." Following training, 95.6% (194/203) of participants responded that they would use a tourniquet in real life. When participants were asked about their comfort level with using a tourniquet in real life, there was a statistically significant improvement between their initial response and their response post training (2.5 versus 4.0, based on 5-point Likert scale; P<.001). CONCLUSION: In this hemorrhage control education study, it was found that a short educational intervention can improve laypersons' self efficacy and reported willingness to use a tourniquet in an emergency. Identified barriers to act should be addressed when designing future hemorrhage control public health education campaigns. Community education should continue to be a priority of the "Stop the Bleed" campaign. Ross EM , Redman TT , Mapp JG , Brown DJ , Tanaka K , Cooley CW , Kharod CU , Wampler DA .

PMID- 29455699 TI - Existing Approaches to Chemical, Biological, Radiological, and Nuclear (CBRN) Education and Training for Health Professionals: Findings from an Integrative Literature Review. AB - OBJECTIVES: This review was conducted to explore the literature to determine the availability, content, and evaluation of existing chemical, biological, radiological, and nuclear (CBRN) education programs for health professionals. METHODS: An integrative review of the international literature describing disaster education for CBRN (2004-2016) was conducted. The following relevant databases were searched: Proquest, Pubmed, Science Direct, Scopus, Journals @ OVID, Google Scholar, Medline, and Ichuschi ver. 5 (Japanese database for health professionals). The search terms used were: "disaster," "chemical," "biological," "radiological," "nuclear," "CBRN," "health professional education," and "method." The following Medical Subject Headings (MeSH) terms, "education," "nursing," "continuing," "disasters," "disaster planning," and "bioterrorism," were used wherever possible and appropriate. The retrieved articles were narratively analyzed according to availability, content, and method. The content was thematically analyzed to provide an overview of the core content of the training. RESULTS: The literature search identified 619 potentially relevant articles for this study. Duplicates (n=104) were removed and 87 articles were identified for title review. In total, 67 articles were discarded, yielding 20 articles for all text review, following 11 studies were retained for analysis, including one Japanese study. All articles published in English were from the USA, apart from the two studies located in Japan and Sweden. The most typical content in the selected literature was CBRN theory (n=11), followed by studies based on incident command (n=8), decontamination (n=7), disaster management (n=7), triage (n=7), personal protective equipment (PPE) use (n = 5), and post-training briefing (n=3). CONCLUSION: While the CBRN training course requires the participants to gain specific skills and knowledge, proposed training courses should be effectively constructed to include approaches such as scenario-based simulations, depending on the participants' needs.

PMID- 29455701 TI - Estimating the pathways through which maternal education affects stunting: evidence from an urban cohort in South Africa. AB - OBJECTIVE: To estimate the determinants of stunting using rich data from a birth cohort study from urban South Africa and to examine the various mechanisms, both proximate and distal, through which maternal education affects stunting. DESIGN: Multivariate regression analysis using birth cohort data, where the outcome variable was stunting at age 2 years, and multiple mediator analysis to identify pathways from maternal education to stunting. SETTING: South Africa's largest metropolitan area, Soweto-Johannesburg. SUBJECTS: Participants of Birth to Twenty Plus, a longitudinal cohort study of children born in 1990 (n 691). RESULTS: In multivariate analysis, the birth weight Z-score (-0.084; P<0.001; 95 % CI -0.11, 0.06), the mother's openness towards modern health care, captured by a vaccination score (-0.05; P=0.04; 95 % CI -0.10, -0.00), and a better-quality care environment (-0.015; P=0.04; 95 % CI -0.03, -0.00) were found to be negatively associated with stunting. Having experienced symptoms of illness related to ears and eyes increased the risk of stunting (0.038; P=0.01; 95 % CI 0.01, 0.07). Results of the mediation analysis showed that maternal education had an indirect effect on stunting largely through socio-economic status and the antenatal environment (measured by the birth weight Z-score). CONCLUSIONS: Overall, many of the factors that were protective against stunting in the final analysis, whether they operated through maternal education or not, were related to the mother's contribution to the child's life. This reinforces the idea that to minimise stunting, enhanced antenatal and postnatal services to better support and empower mothers may be important. PMID- 29455702 TI - Room 328. PMID- 29455703 TI - The development of a single health-endorsement logo for South Africa. AB - OBJECTIVE: To develop health-endorsement logos (HEL) for food products indicating healthy choices based on the South African nutrient profile model and to pilot test these logos with consumers. DESIGN: Multistage mixed-methods design. SETTING: Cape Town, South Africa. SUBJECTS: Nine focus group discussions (FGD) were conducted with adult consumers to explore what types of HEL are preferred and why. Based on the findings, ten HEL were designed by a graphic design team. A modified Delphi technique, conducted with experts in the fields of nutrition and food science, was employed to eliminate lowest-scoring HEL and to improve the design of the remaining logos. Participants from the initial FGD participated in pilot testing the improved logos. RESULTS: Participants from FGD (n 67) were positive about a single HEL, stating it would make food labelling less confusing as they did not understand the various HEL used. Participants indicated the logo should include wording related to 'healthy choice' or 'better choice' and pictures/symbols related to health and/or food. During two rounds of scoring and comments by experts (n 19), five logos were eliminated and the design of the remaining five improved. Three of five remaining logos received overall rankings of 3.08/5, 3.28/5 and 3.39/5, respectively, during FGD (n 36) in the pilot testing phase. CONCLUSION: HEL were designed and consumer tested. Three designs were submitted to the national Department of Health to consider for implementation, after further testing, as a tool to assist in addressing the high incidence of non-communicable diseases in South Africa. PMID- 29455704 TI - Role of parental education in reduction of prevalence of childhood undernutrition in Bangladesh. AB - OBJECTIVE: Despite progress, levels of malnutrition among children in Bangladesh are among the highest in the world and this is one of the major causes of death in children. The pace of reduction in the prevalence of undernutrition among children is still relatively low. The present study aimed to examine the association between parental education and childhood undernutrition among Bangladeshi children under 5 years of age when adjusting for potential risk factors. DESIGN: The data set was extracted from a nationally representative survey based on a cross-sectional study, the Bangladesh Demographic and Health Survey (BDHS) 2014. SETTING: The base survey was conducted using a two-stage stratified sample of households. In the first stage, 600 enumeration areas (EA) were selected with probability proportional to EA size (207 EA from urban areas, 393 EA from rural areas). SUBJECTS: A total of 7173 children under 5 years from 17 863 households were considered for the analysis. A modified Poisson regression model was implemented to the data for assessing the relationship between parental education and childhood undernutrition when demographic and socio-economic covariates for the child, parents, households and clustering were adjusted. RESULTS: Higher parental education level was associated with lower levels of stunting and underweight, but not with wasting. Maternal and paternal education were both significantly associated with the reduction in prevalence of childhood undernutrition in Bangladesh. CONCLUSIONS: Paternal education appears equally as important as maternal education in reducing undernutrition prevalence among children under 5 years in Bangladesh.

AB - OBJECTIVE: Previous research indicates that low-income individuals often struggle to consume the recommended amount of fruits and vegetables (F&V). LINK Up Illinois is a farmers' market incentive programme that aims to increase F&V consumption among Supplemental Nutrition Assistance Program (SNAP) recipients by improving access to and affordability of locally grown foods. The present research aimed to identify barriers to F&V consumption that exist among users of the LINK Up Illinois programme. DESIGN: Cross-sectional. SETTING: Farmers' markets in Chicago, Springfield, Northbrook, Woodstock, Aurora and Urbana, IL. SUBJECTS: In 2016, a volunteer sample of 140 LINK Up Illinois users (mean age 42.5 years; 81.7 % female; 28.7 % African American; 44.0 % obese) completed a survey at participating farmers' markets across the state. Information on demographics, food shopping behaviours, programme satisfaction, barriers to F&V consumption and frequency of F&V consumption was collected and examined. RESULTS: Approximately 23 % of survey participants reported consuming F&V >=3 times/d. The barriers to F&V consumption most often reported by survey participants were the cost of F&V (29.5 %), spoilage (18.6 %), knowing how to cook F&V (8.7 %) and not thinking about F&V when hungry (8.6 %). Results from multivariable-adjusted logistic regression models suggested that reporting one or more barriers was associated with reduced odds of consuming vegetables >=3 times/d, but not fruits. CONCLUSIONS: Cost, spoilage and knowledge of cooking are key barriers to F&V consumption that exist among LINK Up Illinois users. Strategies are needed to mitigate these barriers and increase F&V consumption in this population. PMID- 29455706 TI - Review: The potential of seminal fluid mediated paternal-maternal communication to optimise pregnancy success. AB - Artificial insemination has been a landmark procedure in improving animal agriculture over the past 150 years. The utility of artificial insemination has facilitated a rapid improvement in animal genetics across agricultural species, leading to improvements of growth, health and productivity in poultry, swine, equine and cattle species. The utility of artificial insemination, as with all assisted reproductive technologies side-steps thousands of years of evolution that has led to the development of physiological systems to ensure the transmission of genetics from generation to generation. The perceived manipulation of these physiological systems as a consequence of assisted reproduction are points of interest in which research could potentially improve the success of these technologies. Indeed, seminal fluid is either removed or substantially diluted when semen is prepared for artificial insemination in domestic species. Although seminal fluid is not a requirement for pregnancy, could the removal of seminal fluid from the ejaculate have negative consequences on reproductive outcomes that could be improved to further the economic benefit of artificial insemination? One such potential influence of seminal fluid on reproduction stems from the question; how does the allogeneic foetus survive gestation in the face of the maternal immune system? Observation of the maternal immune system during pregnancy has noted maternal immune tolerance to paternal specific antigens; a mechanism by which the maternal immune system tolerates specific paternal antigens expressed on the foetus. In species like human or rodent, implantation occurs days after fertilisation and as such the mechanisms to establish antigen-specific tolerance must be initiated very early during pregnancy. We and others propose that these mechanisms are initiated at the time of insemination when paternal antigens are first introduced to the maternal immune system. It is unclear whether such mechanisms would also be involved in domestic species, such as cattle, where implantation occurs weeks later in gestation. A new paradigm detailing the importance of paternal-maternal communication at the time of insemination is becoming evident as it relates to maternal tolerance to foetal antigen and ultimately pregnancy success.

PMID- 29455708 TI - Developing Public Health Initiatives through Understanding Motivations of the Audience at Mass-Gathering Events. AB - This report identifies what is known about audience motivations at three different mass-gathering events: outdoor music festivals, religious events, and sporting events. In light of these motivations, the paper discusses how these can be harnessed by the event organizer and Emergency Medical Services. Lastly, motivations tell what kinds of interventions can be used to achieve an understanding of audience characteristics and the opportunity to develop tailor made programs to maximize safety and make long-lasting public health interventions to a particular "cohort" or event population. A lot of these will depend on what the risks/hazards are with the particular populations in order to "target" them with public health interventions. Audience motivations tell the event organizer and Emergency Medical Services about the types of behaviors they should expect from the audience and how this may affect their health while at the event. Through these understandings, health promotion and event safety messages can be developed for a particular type of mass-gathering event based on the likely composition of the audience in attendance. Health promotion and providing public information should be at the core of any mass-gathering event to minimize public health risk and to provide opportunities for the promotion of healthy behaviors in the local population. Audience motivations are a key element to identify and agree on what public health information is needed for the event audience. A more developed understanding of audience behavior provides critical information for event planners, event risk managers, and Emergency Medical Services personnel to better predict and plan to minimize risk and reduce patient presentations at events. Mass-gathering event organizers and designers intend their events to be positive experiences and to have meaning for those who attend. Therefore, continual vigilance to improve public health effectiveness and efficiency can become best practice at events. Through understanding the motivations of the audience, event planners and designers, event risk managers, and emergency medical personnel may be better able to understand the motivation of the audience and how this might impact on audience behavior at the event.

AB - : Introduction The incidence of natural disasters is increasing worldwide, with countries the least well-equipped to mitigate or manage them suffering the greatest losses. Following natural disasters, ill-prepared foreign responders may become a burden to the affected population, or cause harm to those needing help. Problem The study was performed to determine if international guidelines for foreign workers in the health sector exist, and evidence of their implementation. METHODS: A structured literature search was used to identify guidelines for foreign health workers (FHWs) responding to natural disasters. Analysis of semi structured interviews of health sector responders to the 2015 Nepal earthquake was then performed, looking at preparation and field activities. RESULTS: No guidelines were identified to address the appropriate qualifications of, and preparations for, international individuals participating in disaster response in the health sector. Interviews indicated individuals choosing to work with experienced organizations received training prior to disaster deployment and described activities in the field consistent with general humanitarian principles. Participants in an ad hoc team (AHT) did not. CONCLUSIONS: In spite of need, there is a lack of published guidelines for potential international health sector responders to natural disasters. Learning about disaster response may occur only after joining a team. Dunin-Bell O . What do they know?

AB - PURPOSE: Although the 2016 Japanese guidelines for the management of sepsis recommend de-escalation of treatment after identification of the causative pathogen, adherence to this practice remain unknown. The objective of this study was to evaluate the benefits of de-escalating treatment for sepsis patients at an advanced critical care and emergency medical centre. METHODS: Based on electronic patient information, 85 patients who were transported to the centre by ambulance, and diagnosed with sepsis between January 2008 and September 2013 were enrolled and evaluated. Patients were divided into two groups with and without de escalation, and comparisons were conducted for several variables, including length of hospital stay, and length of antibiotic administration. Two types of subgroup analysis were conducted between patients with septic shock or positive blood cultures. Statistical analysis was conducted using chi-square and Mann Whitney U tests. RESULTS: The length of hospital stay after diagnosis was significantly shorter for the de-escalation group than for the non-de-escalation group. In the subgroup analysis, de-escalation for blood culture-positive patients was beneficial in terms of the length of hospital stay and length of antibiotic administration. CONCLUSIONS: The findings of this study suggest that sepsis treatment de-escalation is beneficial for treatment efficacy and appropriate use of antibiotics.

AB - PURPOSE: This study aims to compare the global prevalence of hepatitis B, hepatitis C, HIV, and tuberculosis in incarcerated adolescents and young adults (AYAs) and older prisoners. METHODS: This study is a systematic review and meta analysis of studies reporting the age-specific prevalence of each infection in prisoners. We grouped age-specific prevalence estimates into three overlapping age categories: AYA prisoners (<25 years), older prisoners (>=25 years), and mixed category (spanning age 25 years). We used random effects meta-analysis to estimate the relative risk (RR) of each infection in AYAs versus older prisoners. RESULTS: Among 72 studies, there was marked heterogeneity in prevalence estimates among AYA prisoners for all infections: hepatitis B (.4%-25.2%), hepatitis C (.0% 70.6%), HIV (.0%-15.8%), and active tuberculosis (.0%-3.7%). The pooled prevalence of HIV (RR = .39, 95% confidence interval .29-.53, I2 = 79.2%) and hepatitis C (RR = .51, 95% confidence interval .33-.78, I2 = 97.8%) was lower in AYAs than in older prisoners. CONCLUSIONS: The prevalence of HIV and hepatitis C is lower in AYA prisoners than in older prisoners. Despite lower prevalence, acquisition begins early among incarcerated populations. There is an urgent need for targeted, age-appropriate prevention, treatment, and harm reduction measures in and beyond custodial settings to reduce the incidence of infection in these extremely vulnerable young people. PMID- 29455714 TI - Using Time-Varying Effect Modeling to Examine Age-Varying Gender Differences in Coping Throughout Adolescence and Emerging Adulthood. AB - PURPOSE: Little is known about how and when coping trajectories differ between males and females. The current study aimed to examine gender differences in the use of specific coping strategies across developmental ages using time-varying effect modeling (TVEM) in a large, diverse community sample. METHODS: A longitudinal study following adolescents across 4 years of high school and 5 years post graduation (N = 1,251) was combined with a nationally representative cross-sectional study of 18- to 22-year-olds (N = 595) to examine changes in gender differences in the use of coping strategies between ages 13 and 25. The same coping questionnaire was administered to both samples. TVEM was used to examine the age-varying prevalence rates of coping in males and females. RESULTS: Gender differences were greatest during middle-to-late adolescence (15-19 years) for active coping, social support seeking, planning, and venting emotions. Females reported greater use of these strategies than males, but males' use increased over time and became equivalent to females after the age of ~19-20. Gender differences in the use of humor did not emerge until the age of 22, at which point the use of humor increased continuously among males but remained stable among females. The use of denial was fairly stable across time, with no gender differences at any age. CONCLUSIONS: Findings highlight the utility of TVEM for advancing our knowledge on gender and coping across developmental time, as males and females used coping strategies at differing rates throughout adolescence and emerging adulthood. Implications for tailoring gender- and age specific intervention efforts to improve coping and related health behaviors are discussed.

PMID- 29455716 TI - How Collegiate Fraternity and Sorority Involvement Relates to Substance Use During Young Adulthood and Substance Use Disorders in Early Midlife: A National Longitudinal Study. AB - PURPOSE: To assess how social fraternity involvement (i.e., membership and residence) in college relates to substance use behaviors and substance use disorder symptoms during young adulthood and early midlife in a national sample. METHODS: National multi-cohort probability samples of US high school seniors from the Monitoring the Future study were assessed at baseline (age 18) and followed longitudinally via self-administered surveys across seven follow-up waves to age 35. The longitudinal sample consisted of 7,019 males and 8,661 females, of which 10% of males and 10% of females were active members of fraternities or sororities during college. RESULTS: Male fraternity members who lived in fraternity houses during college had the highest levels of binge drinking and marijuana use relative to non-members and non-students in young adulthood that continued through age 35, controlling for adolescent sociodemographic and other characteristics. At age 35, 45% of the residential fraternity members reported alcohol use disorder (AUD) symptoms reflecting mild to severe AUDs; their adjusted odds of experiencing AUD symptoms at age 35 were higher than all other college and noncollege groups except non-residential fraternity members. Residential sorority members had higher odds of AUD symptoms at age 35 when compared with their noncollege female peers. CONCLUSIONS: National longitudinal data confirm binge drinking and marijuana use are most prevalent among male fraternity residents relative to non-members and non-students. The increased risk of substance-related consequences associated with fraternity involvement was not developmentally limited to college and is associated with higher levels of long term AUD symptoms during early midlife. PMID- 29455717 TI - The Role of Hypermasculinity, Token Resistance, Rape Myth, and Assertive Sexual Consent Communication Among College Men. AB - PURPOSE: A greater understanding of how college men's gendered beliefs and communication styles relate to their sexual consent attitudes and intentions is essential within the shifting context of negative to affirmative consent policies on college campuses. The results of this study can be used to help design more effective sexual consent interventions. METHODS: Three hundred seventy undergraduate college men completed cross-sectional online surveys. Hierarchical multiple regression examined how hypermasculinity, token resistance, rape myth acceptance, and sexual communication assertiveness were associated with consent related attitudes, intentions, and interpretations. RESULTS: Bivariate correlations among all variables were significant. In multivariate analyses, sexual communication assertiveness was positively associated with all consent outcomes, and token resistance and rape myth acceptance were negatively associated with some. Hypermasculinity was not a significant factor. CONCLUSIONS: Programs seeking to improve sexual consent communication among college men should reduce destructive beliefs and encourage sexually assertive communication. PMID- 29455718 TI - Precollege Sexual Violence Perpetration and Associated Risk and Protective Factors Among Male College Freshmen in Georgia. AB - PURPOSE: Sexual violence (SV) perpetration on college campuses is a serious and prevalent public health issue in the U.S. In response, incoming male freshmen are mandated to receive SV prevention programming. To provide a more effective response, however, we need to understand the SV behaviors of male freshmen before they arrive on campus and the associated factors that contribute to risk and that afford protection, areas that have received limited attention. METHODS: Male freshmen (N = 1,133) across 30 selected 4-year colleges and universities throughout the state of Georgia were recruited for a longitudinal study on SV perpetration. Levels of precollege SV as well as a range of covariates were assessed at baseline. Self-reported SV perpetrators were compared with nonperpetrators on demographic and hypothesized covariates deemed either risk or protective; then risk and protective models were analyzed using binary logistic regression. RESULTS: Weighted analyses revealed that 19.3% self-reported perpetrating SV before college. Before starting college, young men who reported more sexual media consumption, heavy episodic drinking, hypermasculine beliefs, and peers who endorsed SV were more likely to have a history of SV perpetration at college matriculation. Alternatively, men with more knowledge of effective sexual consent and stronger family functioning were less likely to arrive to college with an SV perpetration history. CONCLUSIONS: A significant proportion of incoming male freshmen have perpetrated SV previously. Colleges and universities need to assess incoming freshmen for risk behaviors and negative beliefs and to offer both primary and secondary preventions to more effectively reduce further perpetration.

PMID- 29455719 TI - Community Engagement and Venue-Based Sampling in Adolescent Male Sexually Transmitted Infection Prevention Research. AB - OBJECTIVES: Middle adolescent males are a difficult group to recruit for community sexually transmitted infection (STI) prevention research. We describe a process of community engagement, and venue-based sampling of 14-17-year-old adolescent males, and compare rates of STIs and STI risk behaviors by venue. METHODS: Community engagement consisted of (1) informational meetings with organizations; (2) participation in community meetings and events; (3) hiring community members as study personnel; and (4) an adolescent advisory board recruited from the community. Venues were identified and assessed at different times of the day and days of the week using a structured tool. At selected venues, males ages 14-17 years were invited to participate in a brief survey and provide a urine sample and an optional anal swab for DNA-based STI testing. RESULTS: Venues were assessed (n = 249), and 31 were selected for recruitment, including parks, apartment complexes, community events, entertainment venues, a community school, and community programs for LGBT (gay, lesbian, bisexual, transgender) and adjudicated youth. We enrolled 667 participants, average age 15.7 years. Participants reported high rates of sexual and STI risk behaviors, but had low rates of STIs. These rates differed by venue, with more structured venues recruiting youth reporting fewer STI risk behaviors and less structured venues within the highest STI prevalence zip code recruiting youth reporting more STI risk behaviors. CONCLUSION: Venue-based sampling is a feasible mechanism to target recruitment and enrollment adolescent males with high STI risk behaviors in community settings, with risk profiles varying by setting. PMID- 29455721 TI - Fit4YAMs: Structuring a Lifestyle Intervention for Rural Overweight and Obese Young Adult Males Using Participatory Design. AB - PURPOSE: Young adult males (YAMs) are understudied with respect to lifestyle interventions to address overweight and obesity in this group. This study reports on the participatory design of the structure and delivery of the Fit4YAMs text message-based lifestyle intervention for 18- to 25-year-old rural YAMs in Australia. METHODS: Two semi-structured focus group discussions were held with six overweight or obese YAMs. Sessions explored their preferences for the structure and delivery of a weight loss intervention. Focus groups were recorded, and the contents transcribed verbatim for thematic analysis. RESULTS: The YAMs were unanimous in their preference for a highly personalized intervention program, complete with personalized goal setting, personalized motivation and engagement strategies, and personalized text message content. A text message frequency of three-four messages per week was deemed optimal for this group. Minimal direct contact by the intervention team was requested, but with clear guidelines and reminders of key contacts whom they could contact should they require help and guidance. The YAMs also agreed that a comprehensive goal setting session and personalization session prior to commencement of the intervention would be best. CONCLUSIONS: To engage rural YAMs in lifestyle interventions, a high degree of personalization of the program appears important. Although initially more time and resource intensive than a less personalized approach, it is essential to identify strategies to prevent and reverse weight gain in this hard to engage group. Maximizing their engagement using a more personalized approach could be the key to promoting long-term health outcomes in this group. PMID- 29455722 TI - Computer-Assisted Motivational Interviewing Intervention to Facilitate Teen Pregnancy Prevention and Fitness Behavior Changes: A Randomized Trial for Young Men. AB - PURPOSE: Despite recent declines, teen unintended pregnancy and sexually transmitted infections in the United States remain at levels higher than comparable nations. Initiatives to prevent teen pregnancy have focused primarily on female adolescents; how to effectively engage young men to reduce their risk of fathering a teen pregnancy has not been well studied. We proposed to adapt an innovative computer-assisted motivational interviewing (CAMI) intervention, originally designed and tested with young women, for use with young men, aged 15 24 years, to reduce their risk of fathering a teen pregnancy. This manuscript describes the design of a CAMI intervention for young men aimed at preventing teen pregnancy and improving fitness. METHODS: This randomized controlled trial will recruit 945 sexually active young men between the ages of 15 and 24 years from three health centers in New York City. Participants will be assigned by permuted block randomization to two study arms: one aimed at reducing involvement in unintended teen pregnancy (CAMI-teen pregnancy prevention) and the other at improving overall fitness (CAMI-Fitness). Except for topic, both intervention arms will provide four sessions of Motivational Interviewing coaching and use a mobile app to track behavior and set goals. We will assess young men's sexual and reproductive health behaviors and fitness at baseline, 12, 24, 36, and 64 weeks using a mobile device app created for the study. RESULTS: Pending ongoing study. CONCLUSIONS: Results from the study are expected to enhance our understanding of the efficacy of CAMI to enhance young men's reproductive health and fitness behaviors. PMID- 29455723 TI - Addressing a Critical Gap in U.S. National Teen Pregnancy Prevention Programs: The Acceptability and Feasibility of Father-Based Sexual and Reproductive Health Interventions for Latino Adolescent Males. AB - PURPOSE: The purpose of the research was to examine the feasibility and acceptability of a father-based sexual and reproductive health intervention designed to reduce sexual and reproductive (SRH) disparities and increase correct and consistent condom use among Latino adolescent males. METHODS: The current study conducted in-depth semi-structured interviews with Latino father-son dyads (N=30) designed to elicit perspectives on communication regarding sex and condom use. In addition, the interview protocol included father-son preferences regarding paternal involvement in condom instruction and perceived obstacles and advantages of father direct involvement in education efforts designed to increase correct and consistent condom use among their adolescent sons. Three independent coders conducted both vertical and horizontal analyses of the data to identify emergent themes and reach theoretical saturation. RESULTS: The main findings from this study suggest that Latino fathers can be impactful in shaping Latino adolescent male sexual decision-making and correct and consistent condom use. However, our data highlight that while both feasible and acceptable, Latino fathers identify needing additional support in how best to communicate and seek opportunities to master their own knowledge and skills regarding condom use and effective communication with their adolescent sons about sex. CONCLUSIONS: Latino father-based interventions represent an acceptable and feasible option for building upon the recent success of U.S. national efforts to reduce teen pregnancy rates and STI disparities among Latino youth. However, there exists a need for father-based programs that will support Latino fathers in best educating their sons about condom use and better addressing their SRH. Ongoing national efforts to reduce Latino teen SRH disparities warrant the consideration of father son interventions for Latino adolescent males in the United States. PMID- 29455724 TI - Adolescent and Young Adult Male Mental Health: Transforming System Failures Into Proactive Models of Engagement. AB - Adolescent and young adult men do poorly on indicators of mental health evidenced by elevated rates of suicide, conduct disorder, substance use, and interpersonal violence relative to their female peers. Data on global health burden clearly demonstrate that young men have a markedly distinct health risk profile from young women, underscoring different prevention and intervention needs. Evidence indicates that boys disconnect from health-care services during adolescence, marking the beginning of a progression of health-care disengagement and associated barriers to care, including presenting to services differently, experiencing an inadequate or poorly attuned clinical response, and needing to overcome pervasive societal attitudes and self-stigma to access available services. This review synthesizes key themes related to mental ill health in adolescent boys and in young adult men. Key social determinants are discussed, including mental health literacy, self-stigma and shame, masculinity, nosology and diagnosis, and service acceptability. A call is made for focused development of policy, theory, and evaluation of targeted interventions for this population, including gender-synchronized service model reform and training of staff, including the e-health domain. Such progress is expected to yield significant social and economic benefits, including reduction to mental ill health and interpersonal violence displayed by adolescent boys and young adult men.

AB - Escin, as an internally applied anti-inflammatory agent, has been widely used in the treatment of inflammation and edema resulting from trauma or operation in the clinic. However, the effect of its external use on cutaneous inflammation and edema remains unexplored. In the present study, the anti-inflammatory and anti edematous effects of external use of escin were studied in carrageenan-induced paw edema and histamine-induced capillary permeability in rats, paraxylene induced ear swelling in mice, and cotton pellet-induced granuloma in rats. Effects of external use of escin gel on prostaglandin E2 (PGE2), tumor necrosis factor-alpha (TNF-alpha), and interleukin-1beta (IL-1beta) were determined by ELISA. The anti-inflammatory mechanism was explored by detecting the expression of glucocorticoid receptor (GR) with Western blotting and Real-time PCR analyses, with further exploration of nuclear factor-kappaB (NF-kappaB), p38 mitogen activated protein kinase (P38MAPK) and activator protein-1 (AP-1) expressions. We demonstrated that external use of escin showed significant anti-inflammatory effects on acute and chronic inflammation in different animal models and its anti inflammatory effects might be related to down-regulation of PGE2, TNF-alpha, and IL-1beta. The results also showed that escin exerted its anti-inflammatory effects by promoting the expression of GR, with the possible mechanism being inhibition of the expressions of GR-related signaling molecules such as NF-kappaB and AP-1. PMID- 29455726 TI - Synthesis and biological evaluation of novel tanshinone IIA derivatives for treating pain. AB - Due to ineffectiveness and side effects of existing analgesics, chronic pain has become one of the most complex and difficult problems in the clinic. Monoacylglycerol lipase (MAGL) is an essential hydrolase in the endocannabinoid system and has been identified as a potential target for the treatment of pain. In the present study, we designed and synthesized twelve tanshinone IIA analogs and screened their activity against MAGL. Selected compounds were tested for analgesic activity in vivo, with the acetic acid writhing test model. Among the test compounds, compound III-3 (IC50 120 nmol.L-1) showed significant activity against MAGL and ameliorated the clinical progression in the mouse pain model. Additionally, compound III-3, substitution with N-methyl-2-morpholinoacetamide, demonstrated improved solubility relative to tanshinone IIA. PMID- 29455727 TI - Enhancement of gut permeation of amoxicillin with Nigella sativa seed extract and its phytochemical screening. AB - The seeds of Nigella sativa Linn. (Ranunculaceae), commonly known as Black cumin, are predominantly used as carminative, antispasmodic, and stimulant. The main objective of the present study was to evaluate the effect of N. sativa seed extract on the permeation of co-infused amoxicillin across the gut wall. The methanolic extract of N. sativa improved intestinal permeability of amoxicillin in in-vitro experiments in a dose-dependent manner. Two new glycosides, decanyl nigelloic acid diglucoside [n-decanyl-3-aldehydic-4-methoxy-5-hydroxy benzoate-5 beta-D-glucofuranosyl (2->1)-beta-D-glucopyranosyl-(2->1)-beta-D glucopyranoside]] and nigelabdienoyl triglucoside [homo-labd-5, 9(11)-dien-16 onyl-beta-D-glucopyranosyl (2->1)-beta-D-glucopyranosyl (2->1)-beta-D glucopyranoside], along with seven known fatty acid glycerides/esters, were isolated from the gut permeation enhancing extract. The structures of these new glycosides were elucidated by detailed spectroscopic analyses. PMID- 29455728 TI - Novel triterpene saponins isolated from Clematis mandshurica and their inhibitory activities on NO production. AB - Four new triterpene saponins, mandshunosides F-I (1-4), together with five known compounds (5-9), were isolated from the roots and rhizomes of Clematis mandshurica. Their structures were elucidated on the basis of spectroscopic evidences and hydrolysis products. Bisdesmosidic saponin (3-9) showed modest suppression of NO production with the inhibition ratios in the range of 51.3%- 64.6% at 50 MUmol.L-1, whereas monodesmosidic saponins with a free carboxyl group at C-28 (1 and 2) showed potent inhibitory activities with IC50 values being 12.7 and 8.3 MUmol.L-1, respectively. PMID- 29455729 TI - Three new alkaloids isolated from the stem tuber of Pinellia pedatisecta. AB - The present study was designed to determine the chemical constituents of the stem tuber of Pinellia pedatisecta. The chemical constituents were isolated and purified by various chromatographic techniques, and their structures were elucidated on the basis of physicochemical properties and spectral data. Three new alkaloids (compounds 1, 2, and 3) were obtained and identified as 9-((5 methoxypyridin-2-yl)methyl)-9H-purin-6-amine (1), 4-(2-(2, 5-dioxopyrrolidin-1 yl)ethyl)phenyl acetate (2), and N-(9-((5-methoxypyridin-2-yl)methyl)-9H-purin-6 yl)acetamide (3). These compounds were evaluated for their cytotoxicity against human cervical cancer HeLa cells. Compounds 1 and 3 significantly inhibited the proliferation of HeLa cells with IC50 values being 3.02 +/- 0.54 and 7.16 +/- 0.62 MUmol.L-1, respectively. PMID- 29455730 TI - Enhancement of oral bioavailability and immune response of Ginsenoside Rh2 by co administration with piperine. AB - Ginsenoside Rh2 (Rh2) is one of the major bioactive ginsenosides in Panax ginseng. However, the oral bioavailability of Rh2 is low, with P-glycoprotein (P gp) and CYP3A4 being reported to be the main factors. The purpose of the present study was to determine the enhancing effect of piperine on the oral bioavailability as well as bioactivity of Rh2. The inhibitory effect of piperine on P-gp and CYP3A4 was determined using a Caco-2 monolayer model and a recombinant CYP3A4 metabolic system, respectively. The pharmacokinetics of oral Rh2 (10 mg.kg-1) administered alone or in combination with piperine (10 and 20 mg.kg-1) was performed in rats. The immune boosting effect of Rh2 was assessed in rats by measuring IL-12 level after treated by Rh2 alone or co-administered with piperine. The results indicated that piperine significantly increased the permeability of Rh2 and inhibited the metabolism of Rh2. The pharmacokinetic study results showed that the AUC of Rh2 was significantly increased in combination with piperine at high dose (20 mg.kg-1) when compared to the control group, with relative bioavailability of 196.8%. The increase of Rh2 exposure led to increased serum levels of IL-12. In conclusion, piperine may be used as a bioenhancer to improve pharmacological effect of Rh2 when given orally. PMID- 29455731 TI - Rapid screening and identification of sesquiterpene lactones in Kudiezi injection based on high-performance liquid chromatography coupled with linear ion trap orbitrap mass spectrometry. AB - Sesquiterpene lactones are considered as the major active compounds in Kudiezi injection in virtue of their special structures and activities. Herein, an analytical method was developed for rapid screening and identification of sesquiterpene lactones in Kudiezi injection using high-performance liquid chromatography coupled with linear ion trap-orbitrap mass spectrometry (HPLC-LTQ Orbitrap) in negative ion mode. First, two sesquiterpene lactone reference standards were analyzed to obtain their characteristic ESI-MS/MS fragmentation patterns. Second, based on extracted ion chromatography (EIC) data-mining method and characteristic fragmentation pathways analysis, sesquiterpene lactones in Kudiezi injection were rapidly screened and identified. Finally, an important parameter Clog P was adopted to discriminate the isomers of sesquiterpene lactones. As a result, 50 sesquiterpene lactones were characterized, including 9 sesquiterpene lactone aglycones, 39 sesquiterpene lactone glycosides, and 2 amino acid-sesquiterpene lactone conjugates. Among them, 13 compounds were tentatively identified as new compounds. The results demonstrated that the established method would be a rapid, effective analytical tool for screening and identification of sesquiterpene lactones in the complex system of natural medicines. PMID- 29455732 TI - Morphological and chemical studies of artificial Andrographis paniculata polyploids. AB - Andrographis paniculata (Burm. f.) Nees (AP) is commonly used for the treatment of many infectious diseases and has been cultivated widely in Asian countries, and has been included in United States Pharmacopoeia as a dietary supplement, but the cultivars of A. paniculata are not abundant due to its self-pollinated. With the aims to enrich AP resources and provide materials for after breeding we explored the polyploidy induction. Different explants, colchicine concentration, and treatment time were tested. After identification by flow cytometry, eleven polyploid plants with different morphologic traits were obtained. The agronomic traits and andrographolide concentration of the polyploids were improved greatly. One of the polyploids (serial 3-7) was chosen for further study. The traits of the second and third generation polyploids (serial 3-7) were stable. Compared with the normal plants, the seeds (2nd generation) weight increased by 31%, and the andrographolide concentration of the leaves increased by 14% (2nd) and 28% (3rd). In conclusion, AP autopolyploids with different morphologic traits were established successfully for the first time, and the polyploids induction might be effective for crop improvement of AP. PMID- 29455733 TI - Taxus chinensis ameliorates diabetic nephropathy through down-regulating TGF beta1/Smad pathway. AB - Diabetic nephropathy (DN) is one of the common microvascular complications of diabetes mellitus. Renal fibrosis is closely related to the deterioration of renal function. The present study aimed to investigate protective effect of Taxus chinensis on high-fat diet/streptozotocin-induced DN in rats and explore the underlying mechanism of action. The rat DN model was established via feeding high fat diet for 4 weeks and subsequently injecting streptozotocin (30 mg.kg-1 body weight) intraperitoneally. The rats with blood glucose levels higher than 16.8 mmol.L-1 were selected for experiments. The DN rats were treated with Taxus chinensis orally (0.32, 0.64, and 1.28 g.kg-1) once a day for 8 weeks. Taxus chinensis significantly improved the renal damage, which was indicated by the decreases in 24-h urinary albumin excretion rate, blood serum creatinine, and blood urea nitrogen. Histopathological examination confirmed the protective effect of Taxus chinensis. The thickness of glomerular basement membrane was reduced, and proliferation of mesangial cells and podocytes cells and increase in mesangial matrix were attenuated. Further experiments showed that Taxus chinensis treatment down-regulated the expression of TGF-beta1 and alpha-SMA, inhibited phosphorylation of Smad2 and Smad3. These results demonstrated that Taxus chinensis alleviated renal injuries in DN rats, which may be associated with suppressing TGF-beta1/Smad signaling pathway. PMID- 29455734 TI - Bamboo salt suppresses skin inflammation in mice with 2, 4-dinitrofluorobenzene induced atopic dermatitis. AB - Bamboo salt (BS) is a traditional Korean food, and has been reported to have anti cancer, anti-inflammatory, and anti-metastatic effects. However, the anti-atopic dermatitis (AD) activity of BS has not been described yet. In the present study, we examined the preventive effect of BS on AD. The effect of oral administration of BS was tested in a 2, 4-dinitrofluorobenzene (DNFB)-induced AD animal model, by histological analysis, enzyme-linked immunosorbent assay, reverse transcription-polymerase chain reaction, caspase-1 assay, and Western blotting analysis. BS administration reduced the total clinical severity and scratching frequencies, compared with the AD group. In the serum of DNFB-induced AD mice, the levels of IgE, histamine, thymic stromal lymphopoietin (TSLP), interleukin (IL)-5, and IL-13 were significantly reduced by BS treatment. BS significantly reduced the protein and mRNA expression of TSLP, IL-6, and tumor necrosis factor alpha in the AD skin lesions. BS markedly reduced the infiltration of inflammatory cells. Furthermore, the activation of caspase-1 was reduced by BS in the AD skin lesions. Our results suggested that BS should be considered as a candidate treatment for allergic inflammatory diseases including AD. PMID- 29455735 TI - Corrigendum to "Flow cytometric quantitation of platelet phagocytosis by monocytes using a pH-sensitive dye, pHrodo-SE" [Journal of Immunological Methods 447 (2017) 57-64]. AB - Antibody-mediated phagocytosis of platelets using a flow cytometric monocyte based phagocytosis assay (FMPA) has been shown to predict the outcome of platelet transfusion. The easy adherence between platelets and monocytes even in the absence of an antibody is regarded as one of limitations of the FMPA. To improve the FMPA for prediction of transfusion outcome, we used the pH-sensitive dye pHrodo succinimidyl ester (pHrodo-SE), which has weak fluorescence at neutral pH and has increased fluorescence intensity in low pH conditions such as in lysomes. Platelets stained with pHrodo-SE were sensitized with an HLA class I monoclonal antibody (w6/32 clone) or anti-HLA class I containing antisera. The platelets were incubated with monocyte-enriched mononuclear cells. Phagocytic activity was assessed by the percentage of monocytes that phagocytosed platelets. Sensitization of platelets with w6/32 significantly increased platelet phagocytosis by monocytes in dose- and time-dependent manners. Anti-HLA class I antibody-containing sera caused platelet phagocytosis in a cognate antigen antibody-dependent manner. There was a significant correlation (r=0.69, p<0.01) between phagocytic index and titer of HLA class I antibody measured by lymphocyte immunofluorescence test-flow cytometry. In addition, the phagocytic index obtained by FMPA with pHrodo-SE was significantly higher than that obtained by FMPA with the previously used dye, carboxyfluorescein diacetate succinimidyl ester, when platelets were sensitized by w6/32 and anti-HLA class I antibody containing sera. Because of the higher resolution and higher sensitivity than those of the previous method, the pHrodo-SE-based FMPA may be suitable for more precise quantitation of phagocytosis activity, which would enable qualitative evaluation of transfusion effectiveness. PMID- 29455736 TI - The impact of childhood neighborhood disadvantage on adult joblessness and income. AB - Research on residential inequality focuses heavily on adult economic outcomes as crucial components of the intergenerational transmission of poverty. Yet, empirical evidence on whether youth neighborhoods have a lasting impact on adult economic outcomes at the national level is scarce. Further, we know little about how youth neighborhood effects on adult economic outcomes manifest. This study uses 26 years (14 waves) of restricted panel data from the NLSY79 and the NLSY Children and Young Adults cohorts - data that have never been used to analyze long-term neighborhood effects - to examine whether youth neighborhood disadvantage impacts adult economic outcomes through sensitive years in childhood, teen socialization, duration effects, or cumulative effects. Sibling fixed effects models that net out unobserved effects of shared family characteristics suggest that youth neighborhood disadvantage increases joblessness and reduces income in adulthood. However, exposure across specific developmental stages of youth does not appear to act as a significant moderator while sustained exposure yields pernicious effects on adult economic outcomes. Moreover, these results are robust to alternative variable specifications and cousin fixed effects that net out potentially unobserved confounders, such as the inheritance of neighborhood disadvantage across three generations. PMID- 29455737 TI - Foreclosure migration and neighborhood outcomes: Moving toward segregation and disadvantage. AB - The US housing crisis during the late 2000s was arguably the most devastating residential disaster of the last century, sending millions of families into foreclosure and destroying billions in household wealth. An understudied aspect of the crisis was the spike in local migration that followed the foreclosure surge. In this paper, we assess the residential consequences of these moves, by exploring how foreclosure-induced migration affected the racial and socioeconomic composition of affected families' neighborhoods. To do so, we use the Panel Study of Income Dynamics to track foreclosure, migration, and neighborhood outcomes for samples of white, black, and Hispanic homeowners. Findings from our analysis show clearly that foreclosure was linked to migration to less white and more residentially disadvantaged neighborhoods, with foreclosed Hispanic householders, in particular, tending to move to poorer and more racially isolated neighborhoods. PMID- 29455738 TI - No experience required: Violent crime and anticipated, vicarious, and experienced racial discrimination. AB - There is a growing body of evidence linking racial discrimination and juvenile crime, and a number of theories explain this relationship. In this study, we draw on one popular approach, Agnew's general strain theory, and extend prior research by moving from a focus on experienced discrimination to consider two other forms, anticipated and vicarious discrimination. Using data on black, white, and Hispanic youth, from the Project on Human Development in Chicago Neighborhoods (PHDCN), we find that experienced, anticipated, and to a lesser extent, vicarious discrimination, significantly predict violent crime independent of a set of neighborhood, parental, and individual level controls, including prior violent offending. Additional analyses on the specific contexts of discrimination reveal that violence is associated with the anticipation of police discrimination. The effects tend to be larger for African American than Hispanic youth, but the differences are not statistically significant. These findings support the thesis that, like other strains, discrimination may not have to be experienced directly to influence offending.

AB - Sexual assault on college campuses is a pervasive problem, recently receiving increased scientific and policy attention. However, the high focus on college student experience ignores general population prevalence, trends, and differences between those with college experience and those without. We analyze measures from the National Survey of Family Growth (NSFG) to provide a general population view of experiences with forced intercourse. Forced intercourse is a common experience in the U.S. population, has remained stable in recent years, and varies greatly by gender, age and race. The odds of forced intercourse are also significantly higher among those with less than four years of college. This ubiquitous public health problem is not limited to college campuses. Measures from the NSFG are an important resource for understanding population rates of (and trends in) forced intercourse, providing information to guide interventions and better target scientific investigation. PMID- 29455740 TI - Segregation paradox? School racial/ethnic and socioeconomic composition and racial/ethnic differences in engagement. AB - This study examines the associations between school racial/ethnic and socioeconomic composition and school engagement levels among Mexican-origin Latinos/as, African Americans, and non-Latino/a whites. Prior research suggests that whiter and more affluent schools should promote engagement, but some studies reveal paradoxes of school segregation whereby minority and socioeconomically disadvantaged students exhibit worse outcomes in schools with white and socioeconomically advantaged peers. Using data from the Education Longitudinal Study of 2002, this study examines the associations between the percent of non minority students in the school, average school socioeconomic status, and three engagement outcomes: Liking school, involvement in school-sponsored activities, and coursework engagement. The findings reveal an affective-behavioral trade-off for students in schools with higher proportions of white students. Students who attend whiter schools are less likely to report that they like school, but they are more engaged in coursework. This affective-behavioral paradox is not unique to any particular racial/ethnic group. PMID- 29455741 TI - Young immigrants' host country identification and their friendships with natives: Does relative group size matter? AB - Recent network research indicates that native youth prefer to befriend immigrants with stronger rather than weaker host country identification. Surprisingly, however, no respective preference of high-identifying immigrants for native friends has been found, and there is little evidence that friends influence immigrants' identification. Seeking to make sense of these unexpected findings, my aims are twofold: First, I reproduce an earlier study using three waves of newly collected network panel data. Second, going beyond a robustness test with better data, I suggest that relative group size within school accounts for earlier findings. I hypothesize that immigrants' host country identification only affects their own friendship choices in schools with high shares of immigrants, because only in those schools they can be picky about befriending natives. Stochastic actor-oriented models support this notion, pointing to an interplay of preferences and opportunities in shaping the relation between host country identification and interethnic friendships. PMID- 29455743 TI - Patience moderates the class cleavage in demand for redistribution. AB - Previous studies on class voting have yielded mixed results linking income and demand for redistribution. Why do some poor people oppose redistribution, while some rich people support it? This article argues that an individual's level of patience, an important personal characteristic that influences how people calculate immediate and distinct outcomes, may moderate the effect of class on redistributive preference. In a one-shot game, redistribution between the rich and the poor is zero sum. When people extend their time horizons, however, the poor see the possibility of upward mobility, while the rich emphasize future losses, such as unemployment and economic instability. Consistent with the hypotheses, analyses of the 2014 Cooperative Congressional Election Study and a representative Taiwanese dataset from 2016 reveal a clear class cleavage in demand for redistribution among impatient poor and rich respondents, but the cleavage between their patient counterparts diminished. This pattern of convergence extends previous studies on upward mobility and risk perception theory. PMID- 29455742 TI - Vocational education and employment over the life course using a new measure of occupational specificity. AB - Vocational education is seen as beneficial for the labor market allocation of young people. However, recent studies point to disadvantages later in the life course, where the specific skills that are obtained from vocational education decrease employability. This paper re-evaluates this hypothesis for the Netherlands with an improved measure for the vocational specificity of educational programs, utilizing both vertical (level) and horizontal (field) information on education. More specifically, we use a gradual measure for the linkage strength between education and occupation to predict employment over the life course. Using data from the national Dutch labor force surveys, we show that there is considerable heterogeneity in occupational specificity within the categories of vocational and general educational programs that is masked when using a dichotomous classification of general versus vocational education. In the life course analyses we find that the large early benefits of having vocational education disappear later in the career and turn into a small disadvantage before retirement. PMID- 29455744 TI - Neighbours matter: A nation-wide small-area assessment of environmental inequality in Germany. AB - This study investigates the presence of environmental inequality in Germany and analyses its spatial pattern on a very fine grained level. Using the 2011 German census and pollution measures of the E-PRTR, the study relies on nearly 100,000 one squared km census cells over Germany. SLX and community-fixed SLX models incorporate spatial spillover-effects into the analysis to account for the spatial distribution of socio-demographic characteristics. Results reveal that the share of minorities within a census cell indeed positively correlates with the exposure to industrial pollution. Furthermore, spatial spillover effects are highly relevant: the characteristics of the neighbouring spatial units matter in predicting the amount of pollution. Especially within urban areas, clusters of high minority neighbourhoods are affected by high levels of environmental pollution. This highlights the importance of spatial clustering processes in environmental inequality research. PMID- 29455745 TI - Identifying diverse life transition patterns from adolescence to young adulthood: The influence of early socioeconomic context. AB - The purposes of the present study are to investigate: (1) the heterogeneity in life transition patterns of youth from adolescence to young adulthood (ages 18 30) involving the timing and sequence of four transition events (college graduation, full-time employment, marriage, and parenthood), (2) the influence of early socioeconomic adversity on life transition patterns from adolescence to young adulthood, and (3) the influence of gender and race/ethnicity on these transition patterns. Using a multivariate discrete-time mixture survival model with a sample of 14,503 adolescents from the National Longitudinal Study of Adolescent to Adult Health (Add Health), the study identified four life transition patterns and found that early socioeconomic adversity shapes disrupted life transition patterns from adolescence to young adulthood. Gender and race/ethnicity differences are discussed. These results highlight the need for prevention and intervention programs that selectively target at-risk youth beginning in adolescence and continuing through subsequent transition periods. PMID- 29455746 TI - Today's decisions, Tomorrow's outcomes: Does self-control explain the educational smoking gradient? AB - People with more education tend to have relatively healthy lifestyles. Among other things, they smoke less than those with less education. This link between education and smoking (known as the "educational gradient") is frequently interpreted as causal: many researchers argue that education develops skills, habits, and preferences that discourage smoking and other unhealthy behaviors. However, an alternative possibility is that these skills, habits, and preferences develop early in life and determine the likelihood of both attaining a high level of education and avoiding smoking. I test the latter possibility using data from the Longitudinal Study of Adolescent to Adult Health (Add Health). In particular, I assess the degree to which indicators of self-control in adolescence explain the association between educational attainment and smoking in adulthood. Results from a series of regression-based tests indicate that self-control is a significant predictor of both outcomes, even when controlling for a host of other risk factors. However, it does not appear to explain the educational gradient. PMID- 29455747 TI - Intergenerational social mobility and religious ecology: Disaggregating the conservative Protestant bloc. AB - We extend research on the effects of religious ecologies by examining the role of religious ecologies in intergenerational socioeconomic mobility. We do so first by providing a theoretical framework addressing the diverse cultural influences of religious traditions and their impact on intergenerational mobility. We argue that certain otherworldly orientations among conservative Protestants suppress mechanisms of upward mobility, and that there are meaningful distinctions between sub-groups of conservative Protestants (evangelicals, fundamentalists, and Pentecostals). An analysis of county-level data from the recently released Equality of Opportunity Project and the Churches and Church Membership Survey is used to empirically examine the relationship between religious ecologies and intergenerational mobility. Findings suggest distinct effects of different religious groups on intergenerational mobility. These results demonstrate the importance of accounting for the ecological impact of religion on social mobility in the United States and challenge the conceptualization of conservative Protestants as a monolithic group. PMID- 29455748 TI - Cross-national variation in the social origins and religious consequences of religious non-affiliation. AB - I argue that the social implications of religious non-affiliation vary across cultural contexts, leading to differences across nations in both who is likely to be unaffiliated and the religious consequences of such non-affiliation. I test these propositions by examining cross-national variation in associations with non affiliation using multilevel models and cross-sectional survey data from almost 70,000 respondents in 52 nations. The results indicate that: 1) both individual characteristics (gender, age, and marital status) and nation-level attributes (GDP, communism, and regulation of religion) strongly predict religious non affiliation; 2) differences in non-affiliation by individual-level attributes women vs. men, old vs. young, and married vs. single-are greatest in nations with low levels of religious regulation and high levels of economic development; and 3) the effect of religious non-affiliation on religiosity varies considerably by the political and religious context, and to a lesser extent by the level of economic development in each nation. These results highlight cultural variation in what it means to be religiously unaffiliated. PMID- 29455749 TI - Does social insurance enrollment improve citizen assessment of local government performance? Evidence from China. AB - Although many studies claim that social policies are "carrots" that authoritarian leaders use to garner public support, the assumption that social benefits can boost public support of government has been rarely tested empirically, especially at the local levels. This article investigates the effects of social insurance enrollment on citizens' assessment of local government performance using data from the 2010 China Family Panel Study. We use propensity score matching to reduce selection bias and ordered probit regressions with fixed effects to examine these possible effects. We find that social insurance enrollment had a significant positive effect on rural citizens' assessment of government performance, but this effect did not exist for their urban and migrant peers. This discrepancy could be largely due to the groups' different expectations for government redistribution and their distinct experiences of China's social welfare reform. We conclude that the Chinese authoritarian government has achieved partial success in its attempt to use social policies to maintain popular support. PMID- 29455751 TI - Varieties of political support in emerging democracies: A cross-national analysis. AB - Political support is a multidimensional construct encompassing evaluations of political leaders and institutions (specific support) as well as adherence to basic regime principles (diffuse support). Scholars have traditionally assumed that diffuse and specific support are driven by different forces and evolve largely independently. Prior empirical work, however, has struggled to untangle the two support dimensions and focused predominantly on cross-national differences, ignoring their dynamics. This paper develops an analytical and empirical approach to examine the levels and dynamic interplay of both support dimensions and estimate their determinants, applying it to South American democracies between 1996 and 2015. Contrary to received wisdom, we show that both dimensions are quite volatile and closely linked in this region. In particular, negative economic shocks not only undermine support for government actors, but also fuel democratic disenchantment. Nonetheless, while regime support is rather fickle in South America, it can be ultimately resistant to performance fluctuations. PMID- 29455750 TI - Trigger events and poverty transitions among young adults in Finland after leaving the parental home. AB - Studies have shown that leaving the parental home is associated with an increase in the risk of poverty. However, less is known about poverty dynamics after leaving the nest. Based on Finnish population register data, this research answers the question of how employment and demographic events affect poverty entries and exits among 18- to 24-year-olds in Finland. The follow-up of individuals starts when young adults move away from the parental home. In addition to descriptive methods, discrete-time event-history models are estimated. This study illustrates that changes in employment are typical and are, therefore, often associated with poverty transitions among young adults. Although demographic events are less common, when experienced, they often lead to poverty transitions. This study found that the effects of demographic events vary by gender. This study also illustrates that a move back to the parental home is more likely for some poor population subgroups than for others. PMID- 29455752 TI - Imagining class: A study into material social class position, subjective identification, and voting behavior across Europe. AB - The traditional approach to class voting has largely ignored the question whether material class positions coincide with subjective class identification. Following Sosnaud et al. (2013), this study evaluates party preferences when Europeans' material and subjective social class do not coincide. Seminal studies on voting behavior have suggested that members of lower classes are more likely to vote for the economic left and cultural right and that higher classes demonstrate the opposite pattern. Yet, these studies have on the one hand overlooked the possibility that there is a mismatch between the material class people can be classified in and the class they think they are part of, and on the other hand the consequences of this discordant class identification on voting behavior. Analyzing the 2009 wave of the European Elections Study, we find that the majority of the Europeans discordantly identify with the middle class, whereas only a minority of the lower and higher classes concordantly identify with their material social class. Further, material class only seems to predict economic voting behavior when it coincides with subjective class; for instance, individuals who have an inflated class identification are more likely to vote for the economic left, even when they materially can be classified as middle or high class. We conclude this paper with a discussion on scholarly debates concerning class and politics. PMID- 29455754 TI - Are Concussion Laws Making Youth Athletes Safer? PMID- 29455753 TI - Varieties of indebtedness: Financialization and mortgage market institutions in Europe. AB - During the global housing boom that preceded the 2007-9 financial crisis, household debt increased substantially in many European countries, posing a challenge for literature on financialization and the institutional heterogeneity of mortgage markets. This paper examines recent institutional shifts in European mortgage markets and specifies three analytically distinct models of debt accumulation: inclusion, extension and intensity. While existing research has emphasized inclusion (access to homeownership), we show that financial intensification is an important determinant of cross-national variation in debt. We assess the variation in financial intensity in six European countries (France, Germany, Italy, the Netherlands, Portugal and Spain) using household-level survey data. Our results show that inclusion and expansion explain only part of the cross-national variation in mortgage debt to income ratios. Furthermore, household financial behavior is consistent with the financial intensity model, and variation in the degree of financial intensification explains a substantial portion of the cross-national difference in debt levels.

PMID- 29455756 TI - A Randomized Trial of Weight Change in a National Home Visiting Program. AB - INTRODUCTION: Clinical trials have demonstrated significant impact in reducing weight and incidence of type 2 diabetes mellitus. However, the intensity of these trials limits their scalability to real world settings. The purpose of this study was to embed a lifestyle intervention for overweight and obese mothers within the routine practice of a parent education, home visiting organization. DESIGN: Pragmatic trial that used a stratified random design. SETTING/PARTICIPANTS: Overweight or obese mothers of preschool children located across St. Louis, Missouri, enrolled in Parents As Teachers, a home visiting organization reaching women and children nationwide. INTERVENTION: A lifestyle intervention derived from the Diabetes Prevention Program was embedded within Parents As Teachers entitled Healthy Eating and Active Living Taught at Home (HEALTH). MAIN OUTCOME MEASURES: Outcomes included the proportion of women that achieved 5% weight loss at 24 months and improvements in clinical and behavioral outcomes at 12 and 24 months. Participants were enrolled from 2012 to 2014 and data analysis began in 2016. RESULTS: Women in the usual care versus intervention group were significantly less likely to achieve 5% weight loss at 24 months (11% vs 26%, p=0.01). At 12 months, there was a 2.8-kg difference in weight between groups (p=0.0006), and by 24 months a 4.7-kg difference in weight (3.2 [SD=7.6] kg vs 1.5 [SD=8.3] kg, p=0.002); group differences in waist circumference were also evident by 12 months (2.1 [SD=8.4] cm vs -0.7 [SD=9.8] cm, p=0.04) and 24 months (3.8 [SD=10.6] cm vs -2.5 [SD=9.1] cm, p=0.005), as were improvements in behavioral outcomes. There was no difference in blood pressure between groups. CONCLUSIONS: HEALTH achieved modest but clinically significant weight loss outcomes, and reduced weight gain in mothers of young children. The scalability of this embedded intervention offers the potential to reach mothers in Parents As Teachers programs nationally.

AB - INTRODUCTION: The Special Supplemental Nutrition Program for Women, Infants and Children (WIC) required major revisions to food packages in 2009; effects on nationwide low-income household purchases remain unexamined. METHODS: This study examines associations between WIC revisions and nutritional profiles of packaged food purchases from 2008 to 2014 among 4,537 low-income households with preschoolers in the U.S. (WIC participating versus nonparticipating) utilizing Nielsen Homescan Consumer Panel data. Overall nutrients purchased (e.g., calories, sugar, fat), amounts of select food groups with nutritional attributes that are encouraged (e.g., whole grains, fruits and vegetables) or discouraged (e.g., sugar-sweetened beverages, candy) consistent with dietary guidance, composition of purchases by degree of processing (less, moderate, or high), and convenience (requires preparation, ready to heat, or ready to eat) were measured. Data analysis was performed in 2016. Longitudinal random-effects model adjusted outcomes controlling for household composition, education, race/ethnicity of the head of the household, county quarterly unemployment rates, and seasonality are presented. RESULTS: Among WIC households, significant decreases in purchases of calories (-11%), sodium (-12%), total fat (-10%), and sugar (-15%) occurred, alongside decreases in purchases of refined grains, grain-based desserts, higher fat milks, and sugar-sweetened beverages, and increases in purchases of fruits/vegetables with no added sugar/fats/salt. Income-eligible nonparticipating households had similar, but less pronounced, reductions. Changes were gradual and increased over time. CONCLUSIONS: WIC food package revisions appear associated with improved nutritional profiles of food purchases among WIC participating households compared with low-income nonparticipating households. These package revisions may encourage WIC families to make healthier choices among their overall packaged food purchases.

AB - Rising rates of childhood obesity over the past 2 decades have spurred a number of public- and private-sector initiatives aimed at halting or even reversing this trend. Recognizing common interests in this issue, the Centers for Disease Control and Prevention, NIH, and the Robert Wood Johnson Foundation began conversations about creating a formal collaboration aimed at accelerating efforts to address childhood obesity by coordinating research agendas and providing support for evidence-building activities. The National Collaborative on Childhood Obesity Research (NCCOR) was launched in February 2009, and the U.S. Department of Agriculture joined in 2010. Using the model provided by other previously successful collaborations, such as the Youth Tobacco Cessation Collaborative, NCCOR has emphasized several principles suggested by Petrovich as key elements for successful partnerships: (1) delineate a common purpose by identifying key knowledge gaps in the field; (2) create a shared identity around that common purpose; (3) develop structures for democratic and respectful collaboration so as to strategically coordinate efforts for maximum national impact; (4) identify effective leaders capable of articulating challenges in the field and inspiring a commitment of minds and the resolve to address identified needs; (5) facilitate continuous knowledge exchange and synthesis to keep the field informed; and (6) support assessment of progress and feedback loops for ensuring continual progress. This paper examines how NCCOR has used these principles to help build the field of research, evaluation, and surveillance for childhood obesity prevention and management. PMID- 29455760 TI - Developing a Partnership for Change: The National Collaborative on Childhood Obesity Research. AB - Rising obesity rates in the U.S. over the past several decades, particularly among children and adolescents, led to an increased focus on research addressing obesity prevention and public- and private-sector initiatives on healthy eating and physical activity. Groups conducting prevention initiatives recognized that their ability to achieve and sustain cross-sector environmental, policy, and systems-level solutions was hampered by limited evidence in those areas. In 2007, the Centers for Disease Control and Prevention, NIH, and the Robert Wood Johnson Foundation began to discuss forming a partnership that could accelerate progress to prevent childhood obesity by coordinating research and evaluation agendas and collaboratively building an evidence base. This paper describes the formation, structure, and operations of the National Collaborative on Childhood Obesity Research, the resulting partnership between the Centers for Disease Control and Prevention, NIH, the Robert Wood Johnson Foundation, and since 2010, the U.S. Department of Agriculture. It includes a discussion of lessons learned from, and benefits of, this collaborative model.

AB - In the field of medicine and cardiology newer therapy and devices have been launched with a huge promise and a lot of hype. Unfortunately, over the course of time, a good many of them like biovascular scaffold, renal denervation and intra aortic balloon pump have failed to live up to their initial promise so much so that some of them have been withdrawn. The reason for this downfall may be multifold from incomplete understanding of the patho-physiology of disease, incomplete understanding of mechanism of action of the therapy, in-appropriate application in clinical practice, in-efficient therapy development related to flawed trial design, regulatory impediments placed on the trials or deficits in application of scientific techniques. Here-in we investigate the specific reason for failure for some of these therapies and attempt to suggest a way forward. PMID- 29455763 TI - Low major adverse cardiac event rates following bioresorbable vascular scaffold implantation: Impact of implantation technique on treatment outcomes. AB - BACKGROUND AND OBJECTIVE: Studies conducted across the world have reported that the rates of major adverse cardiac events (MACE) following the use of bioresorbable vascular scaffolds (BVS) are comparable to that noted with traditional drug eluting stents (DES). However, there is limited data on the immediate and medium-term clinical outcomes following the use of the Absorb BVS (Abbott Vascular, Santa Clara, SA) in the Indian context. This study was conducted to determine real-world evidence on the immediate and medium-term clinical outcomes in all patients undergoing percutaneous coronary intervention (PCI) with the Absorb BVS. METHODS: Data of all patients who were treated with Absorb BVS at our center were evaluated. Between December 2012 and October 2016, 142 patients underwent PCI with BVS. The MACE rates during hospitalization, at 30days, 3 months, 6 months after PCI, and every 6 months thereafter were the primary endpoints evaluated with median follow up of 13 months. RESULTS: Mean age of the study participants was 53.7+/-11.8years. Intravascular ultrasound imaging was performed in 15.34% of patients. Predilatation and postdilatation were performed in 81.8% and 84.6% of scaffolds, respectively. There were no episodes of MACE during hospitalization. However, 1 BVS-related MACE was observed at the 1 month (0.7%) as well as at the >=12 month (0.8%) follow up visits. At the 6- and 12-month follow up visits, 2 (1.5%) and 3 (2.5%) non-BVS-related MACEs, respectively, were recorded. CONCLUSION: The use of Absorb BVS in this real-world experience was associated with very good immediate and medium-term clinical outcomes.

AB - Heart failure is a common clinical syndrome and a global health priority. The burden of heart failure is increasing at an alarming rate worldwide as well as in India. Heart failure not only increases the risk of mortality, morbidity and worsens the patient's quality of life, but also puts a huge burden on the overall healthcare system. The management of heart failure has evolved over the years with the advent of new drugs and devices. This document has been developed with an objective to provide standard management guidance and simple heart failure algorithms to aid Indian clinicians in their daily practice. It would also inform the clinicians on the latest evidence in heart failure and provide guidance to recognize and diagnose chronic heart failure early and optimize management.

AB - The annual incidence of sudden cardiac death (SCD) in athletes is significantly lower than the general population. However, when SCD occurs in an athlete during sporting event or training, it sends shockwaves in the society and raises questions about cardiovascular effects of sports and exercise. This document reviews the causes and mechanism of SCD in sports and exercise in young and older athletes. In the Indian context, we suggest a 'pre-participation screening' of young and older athletes and consider a 'supervised, graded exercise regime' for the uninitiated, older sports participant. Finally, the document proposes medical infrastructure required to successfully revive a victim of sudden cardiac arrest during a sporting event.

PMID- 29455771 TI - Angiographic predictors of success in antegrade approach of Chronic Total Occlusion interventions in a South Indian population in the contemporary era. AB - : Chronic Total Occlusion (CTO) intervention is a challenging area in interventional cardiology. Presently about 70% of CTO interventions are successful. MATERIALS AND METHODS: This was a single center prospective study of a cohort of all patients undergoing percutaneous coronary intervention (PCI) as elective or adhoc procedure for CTO from August 2014 to June 2015. Only antegrade CTO interventions were included. In all patients the following data were recorded. RESULTS: A total of 210 (8.9% of total PCI (2353) during the study period) CTO patients were followed up. The mean age was 56.54+/-8.9. In the study sixty nine patients (32.9%) presented with chronic stable angina and rest of the patients had history of acute coronary syndrome of which 22.9% (n=48) had unstable angina (UA) or non ST elevation myocardial infarction (NSTEMI) and 44.2% (n=93) had ST Elevation Myocardial Infarction (STEMI). In those with history of ACS, 64.78% (n=92) had ACS during the previous year and remaining 35.22% (n=49) had ACS prior to that. Single vessel CTO was seen in 89.5% (n=188) and two vessel CTO in 10.5% (n=22). LAD was involved in 36.7% (n=77), RCA in 48.1% (n=101), and LCX in 15.2% (n=32). Procedural success in the first attempt was 68.1% (n=143), which increased to 71.42% (n=150) after the second attempt. CTO interventions were more frequently successful when the calcium was absent or minimal (p-0.05), CTO length was <10mm (p<0.01) and good distal reformation (p<0.01). PMID- 29455772 TI - Prenatal diagnosis of congenital heart disease: A review of current knowledge. AB - This article reviews important features to improve the diagnosis of congenital heart disease (CHD) by applying ultrasound in prenatal cardiac screening. As low and high-risk pregnancies for CHD are subject to routine obstetric ultrasound, the diagnosis of structural heart defects represents a challenge that involves a team of specialists and subspecialists on fetal ultrasonography. In this review, the images highlight normal anatomy of the heart as well as pathologic cases consistent with cardiac malposition and isomerism, septal defects, pulmonary stenosis/atresia, aortic malformations, hypoplastic left ventricle, conotruncal anomalies, tricuspid dysplasia, and Ebstein's anomaly, and univentricular heart, among other congenital cardiovascular defects. Anatomical details of most CHD in fetuses were provided by two-dimensional (2D) ultrasound with higher quality imaging, enhancing diagnostic accuracy in a variety of CHD. Moreover, the accuracy of the cardiac defects in obstetrics ultrasound improves the outcome of most CHD, providing planned delivery, aided genetic counseling, and perinatal management. PMID- 29455773 TI - Takotsubo syndrome. AB - Takotsubo syndrome is a reversible acute heart failure frequently precipitated by an emotional or physical stress. The clinical presentation resembles acute coronary syndrome. Pathogenesis is complex and may involve brain-heart axis and neuro-hormonal stunning of the myocardium. Coronary angiography reveals normal epicardial arteries with no obstruction or spasm. NT-ProBNP maybe remarkably elevated. Regional wall motion akinesia (RWMA) of left ventricle extends beyond the territory of one coronary artery. Reduced left ventricle ejection fraction (LVEF) and RWMA recover in 6-12 weeks. Prognosis is generally good. Recent meta analysis shows in-hospital mortality of 1-4.5% and recurrence rate of 5-10% during five year follow-up.

PMID- 29455775 TI - Stress cardiomyopathy of the critically ill: Spectrum of secondary, global, probable and subclinical forms. AB - Stress cardiomyopathy (SC) typically presents as potential acute coronary syndrome (ACS) in previously healthy people. While there may be physical or mental stressors, the initial symptom is usually chest pain. This form conforms to the published Mayo diagnostic criteria, is well reported and as the presentation is initially cardiac, is considered primary SC. Increasingly we see SC develop several days into the hospitalization secondary to medical or surgical critical illness. This condition is more complex, presents atypically, is not easy to recognize and carries a much worse prognosis. Label of Secondary SC is appropriate as it manifests in sicker hospitalized patients with numerous comorbidities. We review the limited but provocative literature pertinent to SC in the critically ill and describe important clues to identify global, subclinical and probable forms of SC. We illustrate the several unique clinical features, demographic differences and propose a diagnostic algorithm to optimize cardiac care in the critically ill.

AB - Our previous research found seven specific factors that cause system delays in ST elevation Myocardial infarction management in developing countries. These delays, in conjunction with a lack of organized STEMI systems of care, result in inefficient processes to treat AMI in developing countries. In our present opinion paper, we have specifically explored the three most pertinent causes that afflict the seven specific factors responsible for system delays. In doing so, we incorporated a unique strategy of global STEMI expertise. With this methodology, the recommendations were provided by expert Indian cardiologist and final guidelines were drafted after comprehensive discussions by the entire group of submitting authors. We expect these recommendations to be utilitarian in improving STEMI care in developing countries. PMID- 29455778 TI - Predictors of obstructive coronary artery disease in women.

PMID- 29455777 TI - Palliative treatment of coronary "atherosclerotic cancer" by drug-eluting or bare metal stents: From oculo-stenotic reflex period to age of precision medicine. AB - Medications and treatments are said to have a palliative effect if they relieve symptoms without having a curative effect on the underlying disease such as atherosclerosis or cancer. Some authors speculated that atherosclerotic coronary artery disease (CAD) could be considered a "cancer of the coronary arterial wall". Although the percutaneous coronary intervention (PCI) has proven to be effective in decreasing mortality rates among patients with acute coronary syndromes, the previous meta-analyses of PCI versus optimal medical therapy for stable CAD have not been able to demonstrate a reduction in major adverse cardiac outcomes. However, few cardiologists discussed the evidence-based benefits of angiogram and PCI for stable CAD, and some implicitly or explicitly overstated the benefits. Recently, the precision medicine is defined as an evidence-based approach that uses innovative tools and biological and data science to customize disease prevention, detection, and treatment, and improve the effectiveness and quality of patient care. Providing patients with accurate and complete information appears to be an effective way to combat the reliance on the oculostenotic reflex. The foundation of precision medicine is the ability to tailor therapy based upon the expected risks and benefits of treatment for each individual patient. As said by Doctor William Osler, "The good physician treats the disease; the great physician treats the patient who has the disease."

AB - Artificial sweeteners are thought to be beneficial for diabetics or obese where refined sugar can be a problem. These low-calorie sweeteners are seemingly safe to use, provide sweetness without calories, and provide a choice of sweet foods to those who otherwise cannot partake them (refined sugars). However, while artificial sweeteners may indeed restrict calories most of them have no beneficial effects on control of diabetes mellitus; rather possibly increase its risk. Additionally, there could be some other safety concerns possibly risk of cancer. PMID- 29455782 TI - Predictors of major adverse cardiac events following elective stenting of large coronary arteries. AB - OBJECTIVE: Diameter of the affected coronary artery is an important predictor of restenosis and need for revascularization. In the present study, we investigated the frequency and potential risk factors for major adverse cardiac events following elective percutaneous coronary intervention (PCI) and stenting of large coronary arteries. METHODS: We reviewed the data of elective candidates of PCI on a large coronary artery who presented to our center. Demographic, clinical, angiographic and follow-up data of the eligible patients were retrieved from our databank. The study characteristics were then compared between the patients with and without MACE in order to find out the probable risk factors for MACE in patients with large stent diameter. RESULTS: Data of 3043 patients who underwent single vessel elective PCI with a stent diameter of >=3.5mm was reviewed. During a median follow up period of 14 months, 64 (2.1%) patients had MACE. TVR was the most common type of MACE that was observed in 29 patients, while 5 patients had cardiac death. Higher serum levels of creatinine, history of cerebrovascular accident (CVA), and use of a drug eluting stent (DES) were significantly associated with MACE. In the multivariate model, history of CVA (odds ratio=5.23, P=0.030) and use of DES (odds ratio=0.048, P=0.011) were the independent predictors of MACE in patients underwent large coronary artery stenting. CONCLUSION: This study showed that prior CVA and the use of BMS were the potential risk factors for MACE in patients who were stented on their large coronary arteries. PMID- 29455783 TI - Simplified percutaneous closure of patent foramen ovale and atrial septal defect with use of plain fluoroscopy: Single operator experience in 110 consecutive patients. AB - OBJECTIVE: Percutaneous closure of patent foramen ovale (PFO) and atrial septal defect (ASD) is routinely performed under general anesthesia or deep sedation and use of transesophageal (TEE) or intracardiac echocardiography, incurring longer duration and higher cost. We have used a simplified, economical, fluoroscopy-only guided approach with local anesthesia, and herein report our data. METHODS: The study includes 112 procedures in 110 patients with PFO (n=75) or ASD (n=35), with use of an Amplatzer occluder, heparin and prophylactic antibiotics. Balloon sizing guided ASD-device selection. All patients received aspirin and clopidogrel for 6 months, when they all underwent TEE. RESULTS: All PFOs but one (98.7%) and all (100%) ASDs were successfully closed with only one complication (local pseudoaneurysm). At the 6-month TEE, there was no residual shunt in PFO patients, but 2 ASD patients had residual shunts. During long-term (4.3-year) follow-up, no stroke recurrence in PFO patients, and no other problems were encountered. Among 54 patients suffering from migraine, symptom relief or resolution was reported by 45 (83.3%) patients. CONCLUSION: Percutaneous placement of an Amplatzer occluder was safe and effective with use of local anesthesia and fluoroscopy alone. There were no recurrent strokes over >4 years. Migraine relief was reported by >80% of patients. PMID- 29455784 TI - Complications after elective percutaneous coronary interventions: A comparison between public and private hospitals. AB - OBJECTIVE: Complications after percutaneous coronary interventions (PCI) are associated with significant morbidity and mortality, although institutional discrepancies can occur when public and private hospitals coexist within the healthcare system. The aim of this study was to compare the in-hospital complication rates and mortality in addition to long-term survival following elective PCI in two reference public and private cardiology hospitals in Rio de Janeiro, Brazil. METHODS: From January 1st 2013 to December 31st 2014, a total of 440 procedures were identified in both hospitals (public: 328 vs. private: 112) and retrospectively analyzed by chart review. RESULTS: There were no significant differences between the two hospitals regarding the total number of procedures with at least one complication (public: 23.8 vs. private: 17.9%, p=0.2) or in hospital mortality rates (public: 0.6% vs. private: 0%, p=0.5). Post-procedural renal insufficiency was more frequent in the private hospital, whereas coronary related complications were more prevalent in the public hospital. After a mean follow up of 30.3 months (SD+/-9.2), the survival rate was also similar. CONCLUSIONS: Clinical complications after elective PCI are common both in public and private hospitals. Meticulous pre-procedural clinical assessment and patient selection as well as adherence to guideline-based practices could minimize the risk of PCI-related adverse events. PMID- 29455785 TI - Esophageal positions relative to the left atrium; data from 293 patients before catheter ablation of atrial fibrillation. AB - AIMS: Three-dimensional rotational angiography (3DRA) of the left atrium (LA) and the esophagus is a simple and safe method for analyzing the relationship between the esophagus and the LA during catheter ablation of atrial fibrillation. The purpose of this study is to describe the location of the esophagus relative to the LA and mobility of the esophagus during ablation procedure. METHODS: From 3/2011 to 9/2015, 3DRA of the LA and esophagus was performed in 326 patients before catheter ablation of atrial fibrillation. 3DRAwas performed with visualization of the esophagus via peroral administration of a contrast agent. The positions of the esophagus were determined at the beginning of the procedure, for part of patients also at the end of procedure with contrast esophagography. RESULTS: The most frequent position is behind the center of the LA (91 pts., 31.9%) The least frequent position is behind the right pulmonary veins (27 pts., 9.4%). The average shift of the esophagus position was 3.36+/-2.15mm, 3.59+/ 2.37mm and 3.67+/-3.23mm for superior, middle and inferior segment resp. CONCLUSIONS: The position of the esophagus to the LA is highly variable. The most common position of the esophagus relative to the LA is behind the middle and left part of the posterior wall of the LA. The least frequently observed position is behind the right pulmonary veins. No significant position change of esophagus motion from before to after the ablation procedure in the majority (>=95%) of the patients was observed. PMID- 29455786 TI - Examination of the appropriate timing of reperfusion therapy for recent myocardial infarction: a Japanese single-center retrospective study. AB - BACKGROUND: The various guidelines clearly mention the treatment strategies for in patient of acute myocardial infarction (MI) presenting more than 24h from symptom onset (recent myocardial infarction, RMI). However, the appropriate timing of reperfusion for RMI is unclear. METHODS: We retrospectively evaluated 525 consecutive MI patients who underwent percutaneous coronary intervention (PCI) in our hospital between January 2008 and December 2012. RESULTS: Sixty RMI patients were more frequently associated with cardiac complications such as myocardial rupture (3.3% vs. 0%; p<0.01), ventricular septal rupture (3.3% vs. 0.4%; p<0.05), and congestive heart failure (15% vs. 2.6%; p<0.001) than 272 consecutive ST-elevation myocardial infarction (STEMI) patients. Of the 60 RMI patients, 33 (55.0%) underwent PCI within 7days (early-PCI group) and 27 (45.0%) underwent PCI after 7days (late-PCI group). Left ventricular ejection fraction measured by echocardiography at second hospital day was similar between the groups. The early-PCI group was more significantly associated with cardiogenic shock and heart failure and more frequently required intra-aortic balloon pumping (24.2% vs. 3.7%; p<0.05) than the late-PCI group. There were no significant differences in 30-day mortality, cardiac complications, and major cardiac events during long-term follow-up (12-36 months) between the groups. CONCLUSION: RMI patients had a higher incidence of cardiac complications than AMI patients. Clinical outcomes were similar between patients undergoing early revascularization and those undergoing late revascularization, although the former group included a higher proportion of patients with severe cardiac failure. PMID- 29455787 TI - Cardiovascular risk factors profile in patients with acute coronary syndrome with particular reference to left ventricular ejection fraction. AB - BACKGROUND: Acute coronary syndrome (ACS) remains a leading cause of death in the United States. Numerous studies have shown that the degree of LV systolic dysfunction is a major if not the most important determinant of long-term outcome in ACS. OBJECTIVES: To identify the most important risk factors and other clinical predictors which might have impact on left ventricular ejection fraction in patients with ACS. RESULTS: The total patients (299) admitted to our center from July, 2015 till December, 2015; with established diagnosis of ACS were classified in to two groups: Group I: 193 patients with impaired LVEF <40% (64.5%), Group II: 106 patients with LVEF equal or >40% (35.5%). The patients of group I were significant elderly compared to those of group II (60.9+/-11.2 vs 56.9+/-10.6; p=0.002), had significant history of DM and CKD (66.3% and 31.1% VS 49.1% and 19.8%; p=0.004 and 0.036 respectively), presented mainly with STEMI- ACS (51.3% VS 28.3% respectively; p<0.001) with +v cardiac biomarker (troponin) (90.2% VS 66.0%; p<0.001). Moreover, patients of group I had more significant ischemic MR compared to the patients of group II (24.9% VS 3.8% respectively; p<0.001) with higher rate of LV thrombus discovered by echocardiography (25.4% VS 1.9%; p<0.001). Extensive significant CAD disease was observed to be higher among patients of group I (69.4% VS 57.5%; p=0.039) and those patients treated mainly with PCI revascularization therapy (68.9% VS 52.8%; p=0.002) compared to patients of group II who mainly treated medically (34.9% VS 17.6 %; p<0.001). Multiple logistic regression analysis demonstrated that DM (odd ratio (OR): 2.64, 95% confidence interval (CI): 1.45-4.79, P=0.01), presence of significant ischemic MR (OR: 13.7, 95% CI:2.84-66.1, p=0.001)and presence of significantly diseased coronary vessels (odd ratio (OR): 5.06, 95% confidence interval (CI): 1.14-22.6, P=0.033,) all were independent predictors for significant LV dysfunction (LVEF <40%) which predict poor outcome in ACS patients. CONCLUSION: We concluded that DM, presence of significant ischemic MR, and increased number, severity of diseased coronaries all were independent predictors of LV dysfunction (LVEF <40%) which is known to predict poor outcome. Identification of those risk predictors upon patient evaluation could be helpful to identify high risk-patients, in need of particular care, aggressive therapy and close follow-up to improve their poor outcome. PMID- 29455788 TI - Presence of coronary artery disease in diabetic and non diabetic South Asian immigrants. AB - INTRODUCTION: South Asian Immigrants (SAIs) are the second fastest growing Asian immigrant population in the US, and at a higher risk of type 2 diabetes (diabetes) and coronary artery disease (CAD) than the general US population. OBJECTIVES: We sought to determine in SAIs the; 1) the prevalence of CAD risk factors in diabetics and non-diabetics; and b) the high possibility of CAD in diabetic SAIs. We also assessed the prevalence of sub-clinical CAD in both diabetics and non-diabetics SAIs using common carotid artery Intima-media thickness (CIMT) as a surrogate marker for atherosclerosis. METHODS: In a cross sectional study design, 213 first generation SAIs were recruited and based on the history, and fasting glucose levels were divided into two subgroups; 35 diabetics and 178 non-diabetics. 12-hour fasting blood samples were collected for glucose and total cholesterol levels. Exercise Tolerance Test (ETT) was performed to determine the possibility of CAD. RESULTS: Both diabetics and non-diabetics SAIs in general, share a significant burden of CAD risk factors. The prevalence of hypertension (p=0.003), total cholesterol >=200mg/dl (p<0.0001) and family history of diabetes (p<0.0001) was significantly was significantly higher in diabetics compared to non-diabetics. Of the 22/29 diabetic participants without known history of CAD, 45% had positive ETT (p<0.001). Similarly, 63.1% of diabetics and 51.8 % of non-diabetics were positive for sub-clinical CAD using CIMT as a marker. CONCLUSION: The susceptibility to diabetes amongst SAIs promotes an adverse CAD risk, as evident by this small study. Further research, including larger longitudinal prospective studies, is required to validate the current small study findings with investigation of the temporal association. PMID- 29455789 TI - Geographical variation in the clinical presentation of endomyocardial fibrosis in India? AB - OBJECTIVES: To compare the clinical presentation, clinical profile and survival of two groups of endomyocardial fibrosis patients. METHODS: The study was a prospective cohort study, or a prospective case series, comparing all consecutive echocardiographically proven patients with endomyocardial fibrosis seen in Medical College Trivandrum with the patients seen in Medical College Hospital, Alappuzha(Alleppey) (or TD Medical College). In all patients the clinical details like age, sex, type of endomyocardial fibrosis, the presence of anaemia, eosinophilia, neutrophilia and type of rhythm(Sinus or atrial fibrillation) etc were compared by both simple X2 and by Kaplan Meier survival curves. RESULTS: The mean age and the sex distribution was same in both places Briefly the incidence of biventricular endomyocardial fibrosis was more from Trivandrum than Alleppey, 64.9% vs 14.3% (p<0.0.001), the incidence of atrial fibrillation was more in Trivandrum 44.2% vs 16.3%. (p<0.001)The overall survival of Trivandrum patients was poorer (p<0.0001). The six year survival was 61% in the Trivandrum population whereas it was 91.5% in the Alleppey population. CONCLUSIONS: These differences may have been due to the better nutrition of the Alleppey patients due to a higher exposure to fish compared to the Trivandrum population. Better nutrition would protect against Magnesium deficiency and prevent the absorption of Cerium in the patients from Alleppey, compared to those from Trivandrum. PMID- 29455790 TI - Insertion/deletion polymorphism of ACE gene in females with peripartum cardiomyopathy: A case-control study. AB - BACKGROUND: The role of polymorphism of Angiotensin converting enzyme (ACE) gene and ACE activity in etiopathogenesis, prognosis, and many other clinical parameters in the various form of the cardiovascular disease has been established to some degree of certainty. The pathophysiology of Peripartum cardiomyopathy (PPCM) remains an area of active research. The main aim of our study was to see pattern of ACE- Insertion/Deletion (I/D) allele in PPCM and its implications on left ventricular performance indices. METHODS: This single-center case-control study included 45 cases and 70 controls. The diagnosis of PPCM was established clinically and echocardiographically. ACE genotyping was done by polymerase chain reaction (PCR) method in all subjects. RESULTS: The II, ID, and DD genotype was present in 16, 18 and 11 of subjects with PPCM and 48, 19 and 3 of controls respectively. The odds ratio for ACE-II genotype in cases vs. controls was 0.253 (95% CI=0.114-0.558; p=0.007), for that of II genotype was 1.93 (95% CI=0.86-4.3; p=0.107) and for DD genotype was 7.225 (95% CI; 1.88-27.6; p=0.0039). Overall frequency of D allele in cases was significantly higher than controls (odds=4.25; 95% CI=2.01-6.7; p=0.0001). Moreover, ejection fraction, left ventricular volume and linear dimensions were worse in patients with DD genotype. CONCLUSION: ACE DD genotype and overall frequency of D allele is significantly higher in patients with PPCM. Also, the presence of DD genotype is associated with worse systolic performance indices measured echocardiographically. PMID- 29455791 TI - Criss-cross heart: Transthoracic echocardiographic features. AB - OBJECTIVE: To study the echocardiographic features of criss-cross heart (CCH), a congenital cardiac anomaly characterized by crossed ventricular inflow streams, in Indian patients. METHODS: In this retrospective observational study, all pediatric echocardiograms performed in a single tertiary care institution in South India over a three-year period were scrutinized for a diagnosis of CCH. Demographic, clinical and echocardiographic data were collected from patients' medical records and echocardiographic database. Crossed ventricular inflow streams was identified when there was inability to visualize both atrio ventricular valves in a single imaging plane in cardiac four chamber view. RESULTS: CCH was diagnosed in five patients from 10,500 pediatric echocardiographic studies. The age at diagnosis ranged from one month to 8 years. Cyanosis was present in all but one of the five cases. Crossed ventricular inflow streams was present by definition in all cases, whereas superior-inferior ventricular relationship was present in only three cases. All cases were associated with ventricular septal defects. Atrio-ventricular discordance was seen in three cases and concordance in two. Ventriculo-arterial discordance was seen in three cases, concordance in one and double outlet right ventricle in one. Three cases had pulmonary stenosis and the other two had pulmonary arterial hypertension. Straddling of AV valve was observed in four cases and hypoplastic aortic arch in one case. CONCLUSION: CCH is an extremely rare congenital cardiac anomaly. Superior-inferior ventricular relationship often co-exists with CCH, but is not necessarily present in all cases. CCH requires early diagnosis because of its common association with diverse cardiac anomalies. PMID- 29455792 TI - Left ventricular structure and diastolic function by cardiac magnetic resonance imaging in hypertrophic cardiomyopathy. AB - OBJECTIVE: Diastolic dysfunction is common in hypertrophic cardiomyopathy (HCM) and hypertensive heart disease (HHD), but its relationships with left ventricular (LV) parameters have not been well studied. Our objective was to assess the relationship of various measures of diastolic function, and maximum left ventricular wall thickness (MLVWT) and left ventricular mass index (LVMI) in HCM, HHD and normal controls using cardiac magnetic resonance imaging (CMR). We also assessed LV parameters and diastolic function in relation to late gadolinium enhancement (LGE) and right ventricular (RV) hypertrophy in HCM. METHODS: 41 patients with HCM, 21 patients with HHD and 20 controls were studied. Peak filling rate (PFR), time to peak filling (TPF), MLVWT and LVMI were measured using CMR. LGE and RV morphology were assessed in HCM patients. RESULTS: MLVWT correlated with TPF in HCM (r=0.38; p=0.02), HHD (r=0.58; p=0.01) and controls (r=0.54; p=0.01); correlation between MLVWT and TPF was weaker in HCM than HHD. LVMI did not correlate with diastolic function. In HCM, LGE extent correlated with MLVWT (tau=0.41; p=0.002) and with TPF (tau=0.29; p=0.02). The HCM patients with RV hypertrophy had higher MLVWT (p<0.001) and TPF (p=0.03) than patients without RV hypertrophy. CONCLUSION: MLVWT correlates with diastolic function (TPF) in HCM, HHD and controls. LVMI did not show significant correlation with TPF. The diastolic dysfunction in HCM is not entirely explained by wall thickening. LGE and RV involvement are associated with worse LV diastolic function, suggesting that these may be markers of more severe underlying myocardial disarray and fibrosis that contribute to diastolic dysfunction. PMID- 29455793 TI - Maternal and fetal outcome in operated vs non-operated cases of congenital heart disease cases in pregnancy. AB - OBJECTIVES: To study pregnancy outcomes in operated vs non-operated cases of congenital heart disease cases during pregnancy. MATERIALS AND METHODS: A total of 55 patients of congenital heart disease who delivered in the authors unit in last 10 years were taken in this retrospective study. These were divided into two groups Group 1:29 (52.7%) patient who had no cardiac surgery and Group 2: 26(47.2%) who had cardiac surgery to correct their cardiac defect before pregnancy. All patients were evaluated for cardiac complications and outcome during pregnancy. Obstetric complications, mode of delivery and fetal outcome was compared in the two groups using statistical analysis. RESULT: The commonest lesion was atrial septal defect (ASD) seen in 22(40%) patients followed by ventricular septal defect (VSD) in 16(29%) .Congenital valvular disease 8(14.5%) and patent ductus arteriosus in 4(7.2%) cases. The mean age was 25.9 +/- 3.15 years in Group 1 and 26.3 +/- 4.53 years in Group 2. The baseline characteristics were similar in the two groups. There was no difference in cardiac complications, NYHA deterioration and need of cardiac drugs in the two groups. Obstetric complications and mode of delivery were also similar in the two groups.Mean birth weight was 2516.65 +/- 514.04 gm in Group 1 and 2683.00 +/- 366.00 gm in Group 2 and was similar. APGAR < 8, stillbirth rate and other neonatal complications were also similar in two groups. CONCLUSION: The maternal and fetal outcome was excellent in patients with congenital heart disease and was similar in unoperated and operated cases. PMID- 29455794 TI - Effect of ventricular function and volumes on exercise capacity in adults with repaired Tetralogy of Fallot. AB - OBJECTIVES: Investigate the effects of left and right ventricular function and severity of pulmonary valve regurgitation, quantified by cardiac magnetic resonance (CMR), on exercise tolerance in adult patients who underwent ToF repair at a young age. METHODS: This is a retrospective cohort study of 52 patients after ToF surgery and 33 age- and sex-matched healthy volunteers. CMR and cardiopulmonary exercise testing (CPET) were performed on all patients; CPET was performed on control subjects. RESULTS: The main finding of CPET was a severe decrease in oxygen uptake at peak exercise VO2peak in TOF patients. The patients were characterized also by lower pulse O2peak and heart rate at peak exercise. Ejection fraction of the right and left ventricles was correlated (r=0,32; p=0,03). Left ventricle ejection fraction was negatively correlated with right ventricular volumes (r=-0,34; p=0,01) and right ventricular mass (r=-046; p<0,00). Right ventricular mass was positively correlated with left ventricular variables (left ventricle end diastolic volume, r=0,43; p=0,002; left ventricle end systolic volume, r=0,54; p<0,00) as was VO2peak: LVEDV (r=0,38; p=0,01); LVESV (r=0,33; p=0,03) and LV mass (r=0,42; p=0,006). CONCLUSION: Exercise intolerance in adults with repaired ToF is markedly depressed. The decreased exercise capacity is correlated with impaired RV function and may be associated also with LV dysfunction, which suggests right-to-left ventricular interaction. PMID- 29455795 TI - Does resting heart rate measured by the physician reflect the patient's true resting heart rate? White-coat heart rate. AB - OBJECTIVES: In cardiology, resting heart rate (HR) and blood pressure (BP) are key elements and are used to adapt treatment. However HR measured in consultation may not reflect true resting HR. We hypothesize that there may be a "white-coat" effect like with BP and that there may be an association between HR variations and BP variations. METHODS: This prospective, monocentric, observational, pilot study (January-April 2016) included 57 consecutive ambulatory patients at Poitiers University Hospital, France (58% male, mean age 64 years). Patients' resting HR and BP were recorded with the same automated blood pressure sphygmomanometer in consultation by the physician then with self-measurement at home. RESULTS: In the overall cohort, we found that HR was significantly higher in consultation (70.5bpm+/-12.6 vs. 68.1bpm+/-10.1, p=0.034). HR also correlated with diastolic BP (r=0.45, p=0.001). Patients were divided into three groups to look for associations with BP: masked HR, (higher HR at home, 38.6%), white-coat HR, (lower HR at home 52.6%) and iso HR, (no change between HR at home and consultation, 8.8%). Although there was no difference between groups in diastolic BP measured in consultation, home diastolic BP was lower in the white-coat HR group (74.3mmHg+/-9.8 vs. 77.9mmHg+/-7.5, p=0.016). CONCLUSIONS: Our study brings to light an exciting idea that could have a major therapeutic and maybe prognostic impact in cardiology: resting HR measured by the physician in consultation does not reflect true resting HR. This must be taken into account to adapt treatment. PMID- 29455797 TI - From the Editor's desk...: March 2018. PMID- 29455796 TI - Percutaneous transradial artery approach for femoro- popliteal artery intervention in the current era in Japan. AB - The percutaneous transradial artery approach for coronary angiography and intervention has been recognized as a safe and effective method, however, it is limited for endovascular therapy (EVT) for femoro-popliteal artery because of lack of devices with longer shaft. Herein, we report two EVT cases for superficial femoral artery disease treated with a long shaft balloon through the radial artery. Although femoro-popliteal artery intervention with this approach has several limits for available devices and technical issues, it is effective for particular patients who are impossible in EVT with femoral artery approach.

PMID- 29455804 TI - Step-by-Step Aortic Valve Replacement With a New Rapid Deployment Valve. AB - PURPOSE: Rapid deployment/sutureless aortic valve replacement is aimed at minimizing the invasiveness of surgical aortic valve replacement. We describe the implantation techniques of a new rapid deployment aortic valve, focusing on its unique and challenging features. DESCRIPTION: The EDWARDS INTUITY Elite aortic valve (Edwards Lifesciences, Irvine, CA) represents a hybrid between the surgical PERIMOUNT Magna Ease (Edwards Lifesciences) pericardial valve, but with advanced features of the percutaneous SAPIEN valve system (Edwards Lifesciences). A flexible delivery system, with a balloon-expandable subannular frame, facilitates insertion. Important implantation steps include an extended oblique "hockey stick" aortotomy, symmetrical annular debridement, intra-annular and supra annular sizing, guiding suture placement, and balloon expansion of the subannular valve frame. EVALUATION: Although this valve provides advantages over conventional aortic valves, its implantation is unique, and special operative considerations must be heeded for optimal outcomes. Implantation requires minimal suturing, enabling smaller incisions. Also, the intra-annular inflow frame may promote improved hemodynamics. CONCLUSIONS: The INTUITY Elite system represents a significant innovation in bioprosthesis technology. It has been shown to be safe and effective, but its implantation requires detailed attention to several unique operative steps. PMID- 29455805 TI - The Coroneo External Annuloplasty Ring.

AB - Sutureless aortic valves are increasingly used for aortic valve replacement (AVR) with excellent outcomes. Implantation requires device expansion in a subannular position within the native aortic root. We report a patient with severe aortic stenosis who received a Perceval sutureless AVR (LivaNova, London, United Kingdom), resulting in a competent prosthesis with an absence of paravalvular leak and aortic regurgitation. However, this implantation resulted in the exacerbation of mitral regurgitation. The sutureless valve required explantation, and a traditional sutured valve was subsequently implanted, which returned the mitral regurgitation to baseline. We discuss a potential etiology of this sutureless AVR-specific complication.

A ventriculotomy with resection of the tumor and patch repair of the IVS was performed with successful relief of LVOT obstruction. The patient was discharged home 6 days later symptom-free. PMID- 29455820 TI - Ductus Aneurysm Ruptured Into the Esophagus With Massive Bleeding. AB - We report a patient with life-threatening hematemesis caused by the rupture of a ductus aneurysm into the esophagus, which was successfully treated by coil embolism for the esophageal fistula through the aorta and subsequent thoracic endovascular aortic replacement. Second-stage therapy was performed surgically after proactive antibiotic treatment and in consideration of the patient's improved general condition. This included debridement with drainage, aortic encasement with remnant aneurysmal wall, omentopexy, and jejunostomy. The esophagus was preserved, and satisfactory healing and natural closure of the fistula were achieved. Although repeated aspirations were later required for pleural fluid, such inflammatory complications finally subsided. PMID- 29455821 TI - Pulmonary Hemorrhage After Arterial Switch Operation. AB - Major aortopulmonary collateral arteries can influence the postoperative course of arterial switch operation, with heart failure being the common clinical presentation. A relatively rare presentation of an aortopulmonary collateral artery in the form of persistent postoperative pulmonary hemorrhage was encountered after an uneventful arterial switch operation in a neonate with transposition of the great arteries, intact interventricular septum, and situs inversus totalis. The aortopulmonary collateral artery was coil embolized with a successful outcome. PMID- 29455822 TI - Pulmonary Hemorrhage Due to Unrecognized Bronchial Collateral After Arterial Switch Operation. AB - We report a neonate with transposition of great arteries and intact ventricular septum who had a massive pulmonary hemorrhage soon after an arterial switch operation. An emergency cardiac catheterization revealed a large bronchial collateral artery from the descending aorta feeding the right lung. The hemorrhage was controlled by coil embolization of the collateral, and the patient recovered after prolonged intensive care.

AB - Repair of tetralogy of Fallot with atrioventricular septal defect may be associated with hemodynamic challenges in the postoperative period particularly as left atrial hypertension secondary to left atrioventricular valve dysfunction may exacerbate pulmonary regurgitation and augment low cardiac output. We present a case describing hybrid strategies to treat severe left atrioventricular and pulmonary valve regurgitation with modified balloon expandable stent valves to counter low cardiac output secondary to valve dysfunction. Such strategies offer an alternative to standard valve choices and should be considered as an extension of the current surgical valve inventory.

AB - A baby with pulmonary atresia with intact ventricular septum and hypoplastic right ventricle, with suspected right ventricle to coronary communications, was operated on for placing an aortopulmonary shunt. Postoperatively, the baby deteriorated with features of myocardial ischemia. Postmortem examination revealed anomalous origin of left coronary artery from pulmonary artery that caused significant coronary ischemia on ligation of the ductus arteriosus. Although coronary anomalies, including right ventricle dependent coronary circulation, has been well described, this is the first report of anomalous origin of coronary artery from pulmonary artery in a baby with pulmonary atresia and intact ventricular septum. PMID- 29455825 TI - Urgent Surgical Approach to Mediastinal Cyst Causing Life-Threatening Tracheal Obstruction. AB - This case describes an urgent surgical approach to a patient with symptoms of rapid progressive respiratory compromise resulting from a massive mediastinal cyst. To relieve tracheal compression, ultrasound-guided percutaneous fine-needle aspiration was performed as an urgent procedure, which immediately improved the patient's airway obstruction and facilitated double-lumen endotracheal intubation. Methylene blue was injected into the cyst through the puncturing needle and accurately marked the margins of the cyst. The cyst was completely resected under thoracoscopy. The signs and symptoms of airway obstruction resolved after the operation, with no recurrence observed during the 1-year follow-up. PMID- 29455826 TI - Spontaneous Regression of Primary Pulmonary Synovial Sarcoma. AB - We report a rare case of primary pulmonary synovial sarcoma that underwent spontaneous regression after a transbronchial biopsy. A 38-year-old woman with a well-demarcated solitary mass shadow on chest roentgenogram was referred to us. A transbronchial biopsy was performed, and immunohistochemical results as well as detection of SYT-SSX1 (SYnovial sarcoma Translocation-Synovial Sarcoma X chromosome breakpoint) transcripts resulted in a diagnosis of synovial sarcoma. A right lower lobectomy was performed during video-assisted thoracoscopic surgery. Pathologic examination revealed widespread coagulative necrosis with feeding arterioles occluded by organized thrombi. To our knowledge, this is the first report of a case of spontaneous regression of primary pulmonary synovial sarcoma.

AB - There is controversy about handling functional mitral regurgitation in patients undergoing aortic valve or proximal aortic operations. We describe a transaortic Alfieri edge-to-edge repair for functional mitral regurgitation that reduces operative excessive invasion and prolonged cardiopulmonary bypass time. Between May 2013 and December 2016, 10 patients underwent transaortic Alfieri edge-to edge mitral repair. There were no operative deaths. The severity of mitral regurgitation immediately after the operation by transesophageal echocardiography was none or trivial in all patients. A transaortic Alfieri edge-to-edge repair for functional mitral regurgitation is a simple and safe approach.

AB - We report a patient with refractory electrical storm after coronary artery bypass grafting who was successfully treated with thoracoscopic sympathectomy. Cardiac arrest with ventricular tachycardia occurred on postoperative day 2, and the patient required emergency support with venoarterial extracorporeal membrane oxygenation. Frequent episodes of ventricular tachycardia prevented cardiac recovery and weaning from mechanical circulatory support. A percutaneous left stellate ganglion block initially demonstrated successful prevention of ventricular tachycardia, and definitive sympathetic denervation was achieved by a left thoracoscopic sympathectomy. The patient remained in normal sinus rhythm and gained recovery of baseline ventricular function, permitting successful decannulation and weaning of inotropic support.

This review provides a comprehensive overview on the achievements in the field of moschamine-related alkaloids. In the isolation part, a detailed structural characterization of moschamine-related alkaloids is followed by their spectral data. Besides the well-known antioxidative activities, other screened biological properties are also outlined. Since their isolation, different protocols have been developed to synthesize these alkaloids. The synthetic part is organized according to the different synthetic methodologies for the formation of key structural elements. PMID- 29455836 TI - The Rigidins: Isolation, Bioactivity, and Total Synthesis-Novel Pyrrolo[2,3 d]Pyrimidine Analogues Using Multicomponent Reactions. AB - Rigidins (2-6) are pyrrolopyrimidine alkaloids isolated from marine tunicates. Since their isolation, refinement of their total syntheses, and biochemical evaluation, interest toward this pyrrolo[2,3-d]pyrimidine scaffold as a medicinal candidate has been triggered. The derivatization of these natural products has led to the discovery of a novel range of 7-deazahypoxanthines, which exhibit extremely potent anticancer activity in human cancer cell lines. A major breakthrough toward the synthesis of rigidin and various rigidin analogues has been the application of multicomponent reactions (MCRs). The rapid assembly of molecular diversity and flexibility displayed by MCRs makes it an attractive strategy for the preparation of rigidin-inspired small molecules. Furthermore, a number of rigidin-like 7-deazaxanthine compounds have been reported in the literature and the popularity of implementing MCRs to construct these 7 deazaxanthines is highlighted here. It is our hope that the synthetic methods described in this chapter will result in the further generation of rigidin inspired compounds that will move on from being "hits" into "leads" in the medicinal chemistry drug discovery pipeline and potentially into anticancer therapeutics.

PMID- 29455839 TI - Discussion of "Effects of radiation and surgery on function and quality of life in rectal cancer patients". PMID- 29455840 TI - Cardiac Surgery Outcomes in Patients With Chronic Lymphocytic Leukemia. AB - BACKGROUND: Surgical outcomes of patients with chronic lymphocytic leukemia (CLL) undergoing cardiac surgery are limited. Our objectives were to investigate hospital morbidity and mortality after open cardiac surgery in CLL versus non-CLL patients. METHODS: From May 1995 to May 2015, 157 patients with CLL and 55,917 without and older than 47 years underwent elective cardiac surgery at Cleveland Clinic. By Rai criteria, 79 CLL patients (56%) were low risk (class 0), 13 (9.1%) intermediate risk (classes I and II), and 38 (27%) high risk (classes III and IV); 12 (8.5%) were in remission. Mean age of CLL patients was 72 +/- 9.0 years, and 18% were women. CLL patients were propensity-score matched to 3 non-CLL patients to compare surgical outcomes. RESULTS: High-risk CLL patients received more blood products than matched non-CLL patients (33/38 [87%] versus 74/114 [65%], p = 0.01), but were less likely to receive cryoprecipitate (0% versus 15/114 [13%], p = .02). Intermediate-risk CLL patients received more platelet units, mean 12 versus 4.6 (p = 0.008). Occurrence of deep sternal wound infection (0% versus 5/471 [1.1%]), septicemia (5/157 [3.2%] versus 14/471 [3.0%]), and hospital mortality (4/157 [2.5%] versus 14/471 [3.0%]) were similar (p > 0.3), independent of prior chemotherapy treatment for CLL. CONCLUSIONS: Although CLL patients did not have higher hospital mortality than non-CLL patients, high-risk CLL patients were more likely to receive blood products. Risks associated with transfusion should be considered when evaluating CLL patients for elective cardiac surgery. Appropriate preoperative management, such as blood product transfusions, and alternative treatment options that decrease blood loss, should be considered for high-risk patients. PMID- 29455841 TI - Actual 10-year survival after hepatic resection of colorectal liver metastases: what factors preclude cure? AB - BACKGROUND: Hepatic resection of colorectal liver metastases is associated with long-term survival. This study analyzes actual 10-year survivors after resection of colorectal liver metastases, reports the observed rate of cure, and identifies factors that preclude cure. METHODS: A single-institution, prospectively maintained database was queried for all initial resections for colorectal liver metastases for the years 1992-2004. Observed cure was defined as actual 10-year survival with either no recurrence or resected recurrence with at least 3 years of disease-free follow-up. Clinical risk score was dichotomized into low (0-2) and high (3-5). Semiparametric proportional hazards mixture cure model was utilized to estimate probability of cure. RESULTS: We included 1,211 patients with a median follow-up for survivors of 11 years. Median disease-specific survival was 4.9 years (95% CI: 4.4-5.3). 295 patients (24.4%) were actual 10 year survivors. The observed cure rate was 20.6% (n = 250). Among 250 cured patients, 192 (76.8%) had no recurrence and 58 (23.2%) had a resected recurrence with at least 3 years of disease-free follow-up. Extrahepatic disease (n = 88), carcinoembryonic antigen >200 ng/mL (n = 119), positive margin (n = 109), and >10 tumors (n = 31) had observed cure rates less than 10%. In cure model analysis, patients with both extrahepatic disease and high clinical risk score (n = 31) had an estimated probability of cure of 3.5%. CONCLUSION: Actual 10-year survival after resection of colorectal liver metastases is 24% with an observed 20% cure rate. Patients with both high clinical risk score and extrahepatic disease have an estimated probability of cure less than 5%. When such factors are identified, strong consideration may be given to preoperative strategies, such as neoadjuvant chemotherapy, to help select patients for surgical therapy.

AB - Rapid growth of hydraulic fracturing for shale gas within the USA and the possibility of shale developments within Europe has created public concern about the risks of spills and leaks associated with the industry. Reports from the Texas Railroad Commission (1999 to 2015) and the Colorado Oil and Gas Commission (2009 to 2015) were used to examine spill rates from oil and gas well pads. Pollution incident records for England and road transport incident data for the UK were examined as an analogue for potential offsite spills associated with transport for a developing shale industry. The Texas and Colorado spill data shows that the spill rate on the well pads has increased over the recorded time period. The most common spill cause was equipment failure. Within Colorado 33% of the spills recorded were found during well pad remediation and random site inspections. Based on data from the Texas Railroad Commission, a UK shale industry developing well pads with 10 lateral wells would likely experience a spill for every 16 well pads developed. The same well pad development scenario is estimated to require at least 2856 tanker movements over two years per well pad. Considering this tanker movement estimate with incident and spill frequency data from UK milk tankers, a UK shale industry would likely experience an incident on the road for every 12 well pads developed and a road spill for every 19 well pads developed. Consequently, should a UK shale industry be developed it is important that appropriate mitigation strategies are in place to minimise the risk of spills associated with well pad activities and fluid transportation movements. PMID- 29455844 TI - [Occipital sinus pericranii: About an unusual situation and review of the literature]. AB - The sinus pericranii refers to a set of clinical presentations that share a pathological communication between the scalp veins and the underlying cranial venous sinus. The nature of this connection ranges from the simple dilatation of the emissary veins, to wide connections through a calvarial bone loss leaving almost the cranial venous sinus in direct contact with the subcutaneous tissue. The authors present the case of an occipital pericranii sinus of intraoperative discovery. Congenital, post-traumatic or spontaneous, this anomaly is most often frontal and located on or close to the midline. The usual clinical presentation is that of a soft mass that empties to the pressure while standing, while it fills in all situations that increase the intracranial pressure (Valsalva maneuver ...). The diagnosis is not always easy to establish, and relies on a bundle of clinical and radiological arguments. Through a review of the literature we propose to focus on the clinical features, diagnostic means and therapeutic options of this rare entity. PMID- 29455845 TI - Single-Cell Resolution of T Cell Immune Responses. AB - Single antigen-specific B or T lymphocytes are the smallest functional units, into which an adaptive immune response can be dissected. Today, novel high throughput technologies are providing researches with increasingly complex information on the diverse phenotypic signatures of individual lymphocytes. With a focus on T cells, we summarize here, how computational approaches are becoming increasingly important to identify the relevant developmental boundaries and connections between these high-dimensional lymphocyte states. We then describe how these insights may be further expanded by novel experimental approaches that allow to map the fate of individual T cells and their progeny in vivo and in vitro. Finally, we highlight how these experiments have uncovered a probabilistic regulatory structure of T cell immune responses and briefly discuss, how two distinct theoretical frameworks used to describe this structure may be merged to best capture single T cell behavior in computational terms. PMID- 29455848 TI - Caveolin-1: The Unnoticed Player in TCR and BCR Signaling. AB - T and B lymphocytes are key players of the adaptive immune system. They recognize pathogenic cues via the T cell antigen receptor (TCR) and the B cell antigen receptor (BCR) to get activated and execute their protective function. TCR and BCR signaling are initiated at the plasma membrane and subsequently propagated into the cell, ultimately leading to cell activation and a protective immune response. However, inappropriate activation of T and B cells can be detrimental to the host resulting in autoimmune disorders, immunodeficiencies, and cancer. The TCR and BCR are located at the plasma membrane, which composition is highly heterogenic. Membrane compartmentalization based on specific lipid-lipid and protein-lipid interactions has raised the interest of the scientific community, converting the plasma membrane into an active player in the initiation of signaling and adding an additional layer of regulation to our current understanding of the functioning of antigen receptors. Caveolin-1 is an integral membrane protein and a crucial component of caveolae. It has been long thought that lymphocytes lack Caveolin-1 expression, due to the absence of detectable caveolae in lymphocytes and the failure to detect Caveolin-1 in T and B cell lines. However, Caveolin-1 is expressed at low levels in primary lymphocytes, and recent studies have shown the importance of Caveolin-1 for the basal membrane organization of the BCR and the TCR as well as their reorganization upon activation. Here, we review our current understanding of the initial signaling events of TCR and BCR activation with respect to receptor compartmentalization on the plasma membrane and with special emphasis on the previously unnoticed role of Caveolin-1. PMID- 29455847 TI - The Fate Choice Between Effector and Memory T Cell Lineages: Asymmetry, Signal Integration, and Feedback to Create Bistability. AB - CD8+ T cells clear primary infections with intracellular pathogens and provide long-term immunity against reinfection. Two different types of CD8+ T cells are responsible for these functions: short-lived effector T cells and memory T cells. The cellular relationship between these two types of CD8+ T cells has been subject to much investigation. Both cell types can derive from a single naive CD8+ T cell precursor. Their generation requires a fate choice early during a T cell response. As a result, two populations of T cells emerge. One of these consists of terminally differentiated short-lived effector T cells. The other contains cells able to develop into long-lived memory T cells. A foundation for development of these two populations may be laid during the first division of an activated naive T cell precursor, as a consequence of asymmetric segregation of fate-determining factors into the daughter cells. Nonetheless, the binary choice between the two lineages is strongly influenced by signals, which ensure that the differentiation process is matched with the needs posed by the infection. Here, we will discuss the genetic and metabolic programs governing differentiation of these two lineages as well as the processes leading to their induction and consolidation to create bistability. These processes involve extensive lateral inhibition between the programs as well as positive feedback between the genetic programs and the signaling pathways responsible for their induction. These features will be highlighted by discussing the role of the Notch signaling pathway in guiding the decision between the two lineages. PMID- 29455846 TI - The Unusual Genetics and Biochemistry of Bovine Immunoglobulins. AB - Antibodies are the key circulating molecules that have evolved to fight infection by the adaptive immune system of vertebrates. Typical antibodies of most species contain six complementarity-determining regions (CDRs), where the third CDR of the heavy chain (CDR H3) has the greatest diversity and often makes the most significant contact with antigen. Generally, the process of V(D)J recombination produces a vast repertoire of antibodies; multiple V, D, and J gene segments recombine with additional junctional diversity at the V-D and D-J joints, and additional combinatorial possibilities occur through heavy- and light-chain pairing. Despite these processes, the overall structure of the resulting antibody is largely conserved, and binding to antigen occurs predominantly through the CDR loops of the immunoglobulin V domains. Bovines have deviated from this general paradigm by having few VH regions and thus little germline combinatorial diversity, but their antibodies contain long CDR H3 regions, with substantial diversity generated through somatic hypermutation. A subset of the repertoire comprises antibodies with ultralong CDR H3s, which can reach over 70 amino acids in length. Structurally, these unusual antibodies form a beta-ribbon "stalk" and disulfide-bonded "knob" that protrude far from the antibody surface. These long CDR H3s allow cows to mount a particularly robust immune response when immunized with viral antigens, particularly to broadly neutralizing epitopes on a stabilized HIV gp140 trimer, which has been a challenge for other species. The unusual genetics and structural biology of cows provide for a unique paradigm for creation of immune diversity and could enable generation of antibodies against especially challenging targets and epitopes. PMID- 29455849 TI - Relationship Between Proximal Aorta Morphology and Progression Rate of Aortic Stenosis. AB - BACKGROUND: The aim of this study was to examine the association between abnormal morphology of the proximal aorta and aortic stenosis (AS) progression rate. The main hypothesis was that morphologic changes of the proximal aorta, such as effacement of the sinotubular junction (STJ), result in increased biomechanical stresses and contribute to calcification and progression of AS. METHODS: Between 2010 and 2012, 426 patients with mild to moderate AS were included in this study. Proximal aortic dimensions were measured at three different levels (i.e., sinus of Valsalva, STJ, and ascending aorta), and sinuses of Valsalva/STJ and ascending aorta/STJ ratios were used to determine degree of aortic deformity. AS progression rate was assessed by annualized increase in mean gradient (median follow-up time, 3.1 years; interquartile range, 2.6-3.9 years). The degree of aortic flow turbulence was examined in 18 matched patients with and without STJ effacement using cardiac magnetic resonance phase-contrast imaging. RESULTS: Patients' mean age was 71 +/- 13 years, and 64% were men. Patients with low ratios had greater AS progression (P < .05). After comprehensive adjustment, sinuses of Valsalva/STJ (P = .025) and ascending aorta/STJ (P = .027) ratios were independently associated with greater AS progression rate. Compared with patients without STJ effacement, those with effacement of the STJ had higher degrees of aortic flow turbulence (24.4% vs 17.2%, P = .038). CONCLUSIONS: Effacement of the STJ is independently associated with greater AS progression, regardless of arterial hemodynamics, aortic valve phenotype, or baseline AS severity. Patients with abnormal proximal aortic geometry had disturbed aortic flow patterns. These findings suggest an interrelation between proximal aorta morphology and stenosis progression.

PMID- 29455850 TI - Proteins involved in the antioxidant and inflammatory response in rutin-treated human skin fibroblasts exposed to UVA or UVB irradiation. AB - BACKGROUND: Rutin, due to its polyphenolic structure, has antioxidant properties and can be used as a cytoprotective compound against UV-induced effects on skin cells. OBJECTIVE: The aim of this study was to examine the effect of rutin on proteomic profile in human skin fibroblasts irradiated with UV dose that induces apoptosis. METHODS: Proteome analysis based on the results obtained by the QExactive OrbiTrap mass spectrometer. RESULTS: Results show that rutin treatment more strongly protects against UVA-induced rather than UVB-induced increases in the total expression of proteins involved in antioxidant (such as SOD, TrxR, and Prxs 1/2) and inflammatory response (e.g., IL-17F, PAK2, and YWHAZ). However, in the case of UVB-irradiated cells, rutin additionally enhances the levels of disulfide-isomerase - an enzyme that is responsible for the formation and breakage of disulfide bonds. Moreover, UVB radiation promotes rutin-Keap1 adduct formation, which leads to the activation of Nrf2, a factor that is responsible for the synthesis of cytoprotective proteins. Furthermore, rutin partially prevents UV-induced apoptosis by restoring the physiological levels of p53, cytochrome c, and cell cycle and apoptosis regulator protein 2 that were increased following irradiation. CONCLUSION: In conclusion, our results show that rutin effectively prevents UV-induced damages associated with proinflammatory and prooxidative activity and protects cells against apoptosis.

AB - Atopic dermatitis (AD), or eczema, is a chronic inflammatory skin condition characterized by relapsing pruritic and dry, scaly lesions. AD affects 10% to 20% of children in the United States and significantly affects the quality of life of patients and their families. Primary care providers (PCPs) are often the first point of contact for the management of AD symptoms. As many as 70% of patients with mild to moderate disease can be managed by a PCP, underscoring the need for these providers to understand basic AD pathophysiology and current standards of care. This article will discuss the basic principles of AD diagnosis and management that PCPs need to optimize patient care, including AD pathogenesis, appropriate use of currently available topical therapies, basic skin care practices, and patient/caregiver counseling points.

AB - OBJECTIVE: Obese youth are more likely to report difficulties with sleep, depression, and quality of life (QOL). This study aims to characterize sleep problems, QOL, and symptoms of depression by degree of obesity. METHOD: The cross sectional study was conducted in a specialized obesity clinic. Obese youth and their caregivers (N = 150) were evaluated with the Child Sleep Habits Questionnaire and Pediatric Quality of Life. Youth completed the Children's Depression Inventory. Regression models and correlations were calculated. RESULTS: Degree of obesity was predictive of increased sleep difficulties and decreased QOL scores. Children's Depression Inventory scores showed that children with more symptoms of depression had more sleep problems, and these were not associated with the degree of obesity. Adolescents with more difficulties sleeping also reported more symptoms of depression and lower QOL. CONCLUSIONS: Degree of obesity negatively affected QOL and sleep variables. Patients with greater sleeping difficulties reported more symptoms of depression. PMID- 29455856 TI - Towards the development of a modeling framework to track nitrogen export from lowland artificial watersheds (polders). AB - Excess nitrogen (N) export from lowland artificial watersheds (polders) is often assumed to be a major contributor to the cultural eutrophication of downstream aquatic ecosystems. However, the complex transport processes characterizing lowland areas pose significant challenges in accurately quantifying their actual role. In this study, we developed a dynamic model to track N sources and transport pathways in lowland polders. The model is able to accommodate all the unique characteristics of polder dynamics, including artificial drainage, and interactions among surface water, groundwater and soil water. Our model was calibrated and validated against water level data and nitrogen concentrations measured in a lowland polder (Polder Jian) in China during the 2014-2016 period. Model performance was satisfactory with an R2 value of 0.55 and an NS value of 0.53 for total N concentrations. The characterization of the various components of water budget and N cycle derived by the model was on par with local empirical estimates. N export from Polder Jian was approximately 57 kg ha-1 yr-1 and was distinctly higher than values reported from nearby non-polder areas. The largest fraction of N export stemmed from seepage. To our knowledge, this is the first dynamic model to quantify N export from a watershed with artificial drainage network and can be used to design remedial measures of ecosystem degradation. PMID- 29455857 TI - Comprehensive Analysis of Constraint on the Spatial Distribution of Missense Variants in Human Protein Structures. AB - The spatial distribution of genetic variation within proteins is shaped by evolutionary constraint and provides insight into the functional importance of protein regions and the potential pathogenicity of protein alterations. Here, we comprehensively evaluate the 3D spatial patterns of human germline and somatic variation in 6,604 experimentally derived protein structures and 33,144 computationally derived homology models covering 77% of all human proteins. Using a systematic approach, we quantify differences in the spatial distributions of neutral germline variants, disease-causing germline variants, and recurrent somatic variants. Neutral missense variants exhibit a general trend toward spatial dispersion, which is driven by constraint on core residues. In contrast, germline disease-causing variants are generally clustered in protein structures and form clusters more frequently than recurrent somatic variants identified from tumor sequencing. In total, we identify 215 proteins with significant spatial constraints on the distribution of disease-causing missense variants in experimentally derived protein structures, only 65 (30%) of which have been previously reported. This analysis identifies many clusters not detectable from sequence information alone; only 12% of proteins with significant clustering in 3D were identified from similar analyses of linear protein sequence. Furthermore, spatial analyses of mutations in homology-based structural models are highly correlated with those from experimentally derived structures, supporting the use of computationally derived models. Our approach highlights significant differences in the spatial constraints on different classes of mutations in protein structure and identifies regions of potential function within individual proteins. PMID- 29455860 TI - A Social-Interactive Neuroscience Approach to Understanding the Developing Brain. AB - From birth onward, social interaction is central to our everyday lives. Our ability to seek out social partners, flexibly navigate and learn from social interactions, and develop social relationships is critically important for our social and cognitive development and for our mental and physical health. Despite the importance of our social interactions, the neurodevelopmental bases of such interactions are underexplored, as most research examines social processing in noninteractive contexts. We begin this chapter with evidence from behavioral work and adult neuroimaging studies demonstrating how social-interactive context fundamentally alters cognitive and neural processing. We then highlight four brain networks that play key roles in social interaction and, drawing on existing developmental neuroscience literature, posit the functional roles these networks may play in social-interactive development. We conclude by discussing how a social-interactive neuroscience approach holds great promise for advancing our understanding of both typical and atypical social development. PMID- 29455859 TI - Heterozygous Mutations in OAS1 Cause Infantile-Onset Pulmonary Alveolar Proteinosis with Hypogammaglobulinemia. AB - Pulmonary alveolar proteinosis (PAP) is characterized by accumulation of a surfactant-like substance in alveolar spaces and hypoxemic respiratory failure. Genetic PAP (GPAP) is caused by mutations in genes encoding surfactant proteins or genes encoding a surfactant phospholipid transporter in alveolar type II epithelial cells. GPAP is also caused by mutations in genes whose products are implicated in surfactant catabolism in alveolar macrophages (AMs). We performed whole-exome sequence analysis in a family affected by infantile-onset PAP with hypogammaglobulinemia without causative mutations in genes associated with PAP: SFTPB, SFTPC, ABCA3, CSF2RA, CSF2RB, and GATA2. We identified a heterozygous missense variation in OAS1, encoding 2,'5'-oligoadenylate synthetase 1 (OAS1) in three affected siblings, but not in unaffected family members. Deep sequence analysis with next-generation sequencing indicated 3.81% mosaicism of this variant in DNA from their mother's peripheral blood leukocytes, suggesting that PAP observed in this family could be inherited as an autosomal-dominant trait from the mother. We identified two additional de novo heterozygous missense variations of OAS1 in two unrelated simplex individuals also manifesting infantile-onset PAP with hypogammaglobulinemia. PAP in the two simplex individuals resolved after hematopoietic stem cell transplantation, indicating that OAS1 dysfunction is associated with impaired surfactant catabolism due to the defects in AMs. PMID- 29455861 TI - Children's Developing Ideas About Knowledge and Its Acquisition. AB - We review key aspects of young children's concept of knowledge. First, we discuss children's early insights into the way that information can be communicated from informant to recipient as well as their active search for information via questions. We then analyze the way that preschool children talk explicitly and cogently about knowledge and the presuppositions they make in doing so. We argue that all children, irrespective of culture and language, eventually arrive at the same fundamental conception of knowledge in the preschool years. Nevertheless, despite the universality of this basic conception, young children are likely to show considerable variation in their pattern of information seeking, depending on the conversational practices of their family and culture. PMID- 29455862 TI - The Developmental Origins of Dehumanization. AB - Dehumanization is a complex social phenomenon, intimately connected to intergroup harm and neglect. However, developmental research has only recently started to investigate this important topic. In this chapter, we review research in areas closely related to dehumanization including children's intergroup preferences, essentialist conceptions of social groups, and understanding of relative status. We then highlight the small number of recent studies that have investigated the development of this social bias more directly. We close by making a series of suggestions for future research that will enable us to better understand the nature and causes of this harmful phenomenon. PMID- 29455863 TI - Trends and Divergences in Childhood Income Dynamics, 1970-2010. AB - Earnings and income variability have increased since the 1970s, particularly at the bottom of the income distribution. Considerable evidence suggests that childhood income levels-captured as average or point-in-time yearly income-are associated with numerous child and adult outcomes. The importance to child development of stable proximal processes during childhood suggests that income variability may also be important, particularly if it is unpredictable, unintentional, or does not reflect an upward trend in family income. Using the Panel Study of Income Dynamics, this study documents trends since the 1970s in three dimensions of childhood income dynamics: level, variability, and growth (n=7991). The analysis reveals that income variability during childhood has grown over time, while income growth rates have not. In addition, the economic context of childhood has diverged substantially by socioeconomic status, race, and family structure, with the most disadvantaged children facing a double-whammy of low income and high variability. PMID- 29455865 TI - Kin Networks and Mobility in the Transition to Adulthood. AB - Family support is critical for launching youth into successful adult lives. Although studies have documented the association between family support and success in the transition to young adulthood, existing work focuses primarily on parental support, giving little attention to extended kin. This narrow definition of family may miss critical exchanges of support, especially among low-income families. Drawing on panel survey data (n=450) and in-depth interviews (n=52) with young women from the Philadelphia Educational Longitudinal Study, this study expands our understanding of family support in the transition to adulthood by examining young adults' kin networks and the types of support and resources embedded within these networks. We find that kin support is an important buffer for those growing up in households without two biological parents, reducing the odds of perceiving oneself as an adult, having a child, and moving out. Qualitative data show that kin often step-in and play a parent-like role, providing needed instrumental and emotional support. Our results also highlight the complexity and fragility of kin network exchanges. While kin networks can be a source of resilience, they are often fragile and subject to external shocks, such as job loss and health declines. Moreover, kin networks can also be a source of obligation, delaying young adults' investments in their own educational trajectories. Those giving back to families are less likely to be in college compared to their peers and more likely to work, live independently, and consider themselves an adult. PMID- 29455864 TI - Social Influence on Positive Youth Development: A Developmental Neuroscience Perspective. AB - Susceptibility to social influence is associated with a host of negative outcomes during adolescence. However, emerging evidence implicates the role of peers and parents in adolescents' positive and adaptive adjustment. Hence, in this chapter we highlight social influence as an opportunity for promoting social adjustment, which can redirect negative trajectories and help adolescents thrive. We discuss influential models about the processes underlying social influence, with a particular emphasis on internalizing social norms, embedded in social learning and social identity theory. We link this behavioral work to developmental social neuroscience research, rooted in neurobiological models of decision making and social cognition. Work from this perspective suggests that the adolescent brain is highly malleable and particularly oriented toward the social world, which may account for heightened susceptibility to social influences during this developmental period. This chapter underscores the need to leverage social influences during adolescence, even beyond the family and peer context, to promote positive developmental outcomes. By further probing the underlying neural mechanisms as an additional layer to examining social influence on positive youth development, we will be able to gain traction on our understanding of this complex phenomenon. PMID- 29455866 TI - Cognition-Action Trade-Offs Reflect Organization of Attention in Infancy. AB - This chapter discusses what cognition-action trade-offs in infancy reveal about the organization and developmental trajectory of attention. We focus on internal attention because this aspect is most relevant to the immediate concerns of infancy, such as fluctuating levels of expertise, balancing multiple taxing skills simultaneously, learning how to control attention under variable conditions, and coordinating distinct psychological domains. Cognition-action trade-offs observed across the life span include perseveration during skill emergence, errors and inefficient strategies during decision making, and the allocation of resources when attention is taxed. An embodied cognitive-load account interprets these behavioral patterns as a result of limited attentional resources allocated across simultaneous, taxing task demands. For populations where motor errors could be costly, like infants and the elderly, attention is typically devoted to motor demands with errors occurring in the cognitive domain. In contrast, healthy young adults tend to preserve their cognitive performance by modifying their actions. PMID- 29455867 TI - Above and Beyond Objects: The Development of Infants' Spatial Concepts. AB - Early in development infants form categorical representations of small-scale spatial relations, such as left vs right and above vs below. This spatial skill allows infants to experience coherence in the layout of the objects in their environment and to note the equivalence of a spatial relation across changes in objects. Comparisons across studies of infant spatial categorization offer insight into the processes that contribute to the development of this skill. Rather than viewing contrasting results across studies as contradictory, identifying how infant spatial categorization tasks recruit distinct processes can not only reconcile findings but also yield insight into the starting points, development, and emerging nature of infants' representations of spatial relations. Also, situating infants' spatial categorization in the context of advances in nonspatial domains may reveal synergistic relations among these domains, particularly in relation to advances in infants' manipulative play with objects and their acquisition of spatial language. A central argument is that broadening the study of infants' spatial categorization may yield further insights into the nature of early spatial concepts and the processes that promote their development.

AB - Bordetella pertussis, the aetiological agent of whooping cough is routinely diagnosed by polymerase chain reaction (PCR) directed at IS481, an insertion sequence target also found in Bordetella holmesii. Recent reports have suggested that B. holmesii infections can be misdiagnosed as pertussis, which can have a significant impact on public health surveillance. This study investigated the presence of B. holmesii in B. pertussis positive clinical samples, in order to determine the incidence of B. holmesii. Clinical cases of pertussis diagnosed by IS481-specific PCR between October 2008 and March 2016 in New South Wales were included. Bordetella holmesii was detected through the simultaneous amplification of IS481 and B. holmesii specific insertions sequence, hIS1001. A total of 46 of 802 patients were identified to be positive for B. holmesii rather than B. pertussis, suggesting an incidence rate of 6.5% in 2009, 16.8% in 2010, 7.6% during 2013 and 8.1% during 2015. Bordetella holmesii infections were diagnosed during and between pertussis epidemics, however cases of B. holmesii and B. pertussis co-infections were not found. The predominant age group of B. holmesii infection was 11-18 years old, which was significantly different to the mean age of B. pertussis infections (0-6 years, p = 0.023). These findings revealed that B. holmesii was co-circulating alongside the B. pertussis epidemic for seven years, hidden from view, as B. holmesii infections have been diagnosed as B. pertussis. Confirmatory testing of B. pertussis positive samples for the presence of B. holmesii, especially during pertussis epidemics, should improve the quality of laboratory diagnosis and laboratory surveillance for pertussis. The presence of B. holmesii in Australia highlights the importance of testing for this pathogen and ongoing molecular surveillance that can guide the control of whooping cough.

AB - Despite recent advances in therapeutic options, lung cancer is the leading cause of death among malignant diseases worldwide. Glutamine-dependence is an established attribute in cancer tissue with emerging importance as a diagnostic and therapeutic target. We analysed the expression of SLC1a5, a major glutamine transporter, in the primary tumour and corresponding nodal metastasis of non small cell lung cancer (NSCLC) to investigate its biological impact. Expression of SLC1a5 was analysed by immunohistochemistry in 259 NSCLC and in 142 nodal metastases and correlated with clinicopathological parameters including overall survival. SLC1a5 expression in the primary tumour and in the corresponding lymph node metastasis revealed a positive correlation (p = 0.005). Moreover, overexpression of SLC1a5 was found to be an independent prognostic factor (p = 0.027) if assessed in lymph node metastases only. SLC1A5 expression was studied for the first time in both primary NSCLC and its corresponding nodal metastasis. Our results indicate that overexpression of SLC1a5 is associated with shorter overall survival. This proved to be an independent prognosticator if assessed in the lymph node metastases. Thus, diagnostics in lymph node metastasis provide superior prognostic information for SLC1a5 overexpression and may open target prediction for future therapeutic options. PMID- 29455872 TI - [PD-L1 expression and PD-1/PD-L1 inhibitors in breast cancer]. AB - The development of immune checkpoints inhibitors represents one of the major recent advances in oncology. Monoclonal antibodies directed against the programmed cell death protein 1 (PD-1) or its ligand (PD-L1) provides durable disease control, particularly in melanoma, lung, kidney, bladder and head and neck cancers. The purpose of this review is to synthesize current data on the expression of PD-L1 in breast cancer and on the preliminary clinical results of PD-1/PD-L1 inhibitors in breast cancer patients. In breast cancer, PD-L1 expression is heterogeneous and is generally associated with the presence of tumor-infiltrating lymphocytes as well as the presence of poor-prognosis factors, such as young age, high grade, ER-negativity, PR-negativity, and HER-2 overexpression, high proliferative index, and aggressive molecular subtypes (triple negative, basal-like, HER-2-overexpressing). Its prognostic value remains controversial when assessed with immunohistochemistry, whereas it seems favorable in triple-negative cancers when assessed at the mRNA level. Early clinical trials with PD-1/PD-L1 inhibitors in breast cancer have shown efficacy in terms of tumor response and/or disease control in refractory metastatic breast cancers, notably in the triple-negative subtype. Many trials are currently underway, both in the metastatic and neo-adjuvant setting. A crucial issue is identification of biomarkers predictive of response to PD-1/PD-L1 inhibitors.

PMID- 29455858 TI - A Large-Scale Multi-ancestry Genome-wide Study Accounting for Smoking Behavior Identifies Multiple Significant Loci for Blood Pressure. AB - Genome-wide association analysis advanced understanding of blood pressure (BP), a major risk factor for vascular conditions such as coronary heart disease and stroke. Accounting for smoking behavior may help identify BP loci and extend our knowledge of its genetic architecture. We performed genome-wide association meta analyses of systolic and diastolic BP incorporating gene-smoking interactions in 610,091 individuals. Stage 1 analysis examined ~18.8 million SNPs and small insertion/deletion variants in 129,913 individuals from four ancestries (European, African, Asian, and Hispanic) with follow-up analysis of promising variants in 480,178 additional individuals from five ancestries. We identified 15 loci that were genome-wide significant (p < 5 * 10-8) in stage 1 and formally replicated in stage 2. A combined stage 1 and 2 meta-analysis identified 66 additional genome-wide significant loci (13, 35, and 18 loci in European, African, and trans-ancestry, respectively). A total of 56 known BP loci were also identified by our results (p < 5 * 10-8). Of the newly identified loci, ten showed significant interaction with smoking status, but none of them were replicated in stage 2. Several loci were identified in African ancestry, highlighting the importance of genetic studies in diverse populations. The identified loci show strong evidence for regulatory features and support shared pathophysiology with cardiometabolic and addiction traits. They also highlight a role in BP regulation for biological candidates such as modulators of vascular structure and function (CDKN1B, BCAR1-CFDP1, PXDN, EEA1), ciliopathies (SDCCAG8, RPGRIP1L), telomere maintenance (TNKS, PINX1, AKTIP), and central dopaminergic signaling (MSRA, EBF2).

AB - In 17 patients who underwent prostate artery embolization for treatment of lower urinary tract symptoms, the accuracy of preprocedural magnetic resonance (MR) angiography was retrospectively compared with intraprocedural digital subtraction angiography (DSA) in the identification of prostatic artery origin. Of 34 vessels, 26 MR angiography identified origins (76.5%) were confirmed by DSA at the time of embolization. Although image postprocessing is required, the ability of MR angiography to accurately identify prostatic artery origins prior to embolization is useful in treatment planning and can obviate the need for separate computed tomographic angiography, thus reducing both radiation dose and time demand on patients.

AB - This case series illustrates a radial access complication seen in 7 of 9 consecutive patients (age range, 44-53 y) undergoing uterine artery embolization in May and June 2017. Demonstrative images and videos identify a transient and clinically consequential skin ischemia caused by intraprocedural saline solution infusion through the occlusive radial artery sheath. All complications documented were classified as mild adverse events (class A) according to Society of Interventional Radiology criteria. Complication severity ranged from transient blanching to ischemic necrosis of the skin. Operator cognizance of this phenomenon with appropriate adjustment of saline solution infusion rates will prevent tissue ischemia and necrosis in radial access cases.

AB - PURPOSE: In spite of good initial therapy response neuroblastomas often spread to distant organs or relapse after periods of remission. Dysregulation of apoptosis, a hallmark of cancer, is often effected by elevated levels of antiapoptotic signals leading to resistance against chemotherapeutic drugs. Inhibitors of apoptosis proteins (IAPs) are crucial cellular apoptosis regulators. Targeting IAPs with Smac mimetics has been demonstrated as a promising strategy for treatment of neuroblastoma and other tumors. METHODS: In paired neuroblastoma cell lines, obtained from the same patient at time of diagnosis (CHLA-15) and postchemotherapy during progressive disease (CHLA-20), expression of crucial IAPs was determined. Furthermore, effects of vincristine on viability, cytotoxicity, apoptosis induction and caspase-3/7 activation were determined. RESULTS: Cellular IAP-1 (cIAP-1) and X-linked IAP (XIAP) expression was increased in cell line CHLA 20. Moreover, biological effects of vincristine were significantly lower in these cells. Treatment of cells with Smac mimetic LCL161 increased the effects of vincristine in CHLA-15 cells and more importantly was able to overcome vincristine resistance in CHLA-20 cells. CONCLUSIONS: These findings demonstrate the potential of Smac mimetics for the development of novel therapeutic approaches for the treatment of relapsed/resistant neuroblastoma.

AB - INTRODUCTION: Parental presence at induction of general anesthesia (PPI) is highly desired by children and parents. However, it often faces resistance from medical personnel. We conducted a survey evaluating the perceptions of surgeons before and after establishment of a PPI program. METHODS: Internal web-based surveys using Likert Scale questions were administered to all members of a pediatric surgical department before and after the introduction of PPI at a freestanding children's hospital. Pre and post results were compared by Wilcoxon rank-sum tests. A p-value <=0.0026 was considered significant due to the Bonferroni correction. RESULTS: The survey was sent to 59 surgeons 1year before and 5years after gradual implementation of PPI. Response rates were 46% and 54%, pre and post implementation, respectively. After implementation, there was a statistically significant increased level of agreement with the statement: "PPI improves the parents' level of satisfaction" (p=0.0025) and a statistically significant decreased level of agreement with the statement "PPI lengthens the duration of induction" (p=0.0001). Before initiation, 56% wanted to see PPI implemented, while after implementation, 97% wanted PPI to remain. CONCLUSIONS: A majority of pediatric surgeons favored maintaining PPI after implementation. Resistance to initiation of PPI should not hinder implementation. TYPE OF STUDY: Survey LEVEL OF EVIDENCE: Not applicable. PMID- 29455887 TI - Nonlinear system identification based on Takagi-Sugeno fuzzy modeling and unscented Kalman filter. AB - This paper proposes two novel Kalman-based learning algorithms for an online Takagi-Sugeno (TS) fuzzy model identification. The proposed approaches are designed based on the unscented Kalman filter (UKF) and the concept of dual estimation. Contrary to the extended Kalman filter (EKF) which utilizes derivatives of nonlinear functions, the UKF employs the unscented transformation. Consequently, non-differentiable membership functions can be considered in the structure of the TS models. This makes the proposed algorithms to be applicable for the online parameter calculation of wider classes of TS models compared to the recently published papers concerning the same issue. Furthermore, because of the great capability of the UKF in handling severe nonlinear dynamics, the proposed approaches can effectively approximate the nonlinear systems. Finally, numerical and practical examples are provided to show the advantages of the proposed approaches. Simulation results reveal the effectiveness of the proposed methods and performance improvement based on the root mean square (RMS) of the estimation error compared to the existing results. PMID- 29455888 TI - Identification of process transfer function parameters in event-based PI control loops. AB - This paper presents a method to estimate the parameters of first and second order systems with time delays with different accuracy levels for autotuning of event based PI control loops. In particular, the event-based sampling condition applied in this work is based on the sampling strategy known as symmetric-send-on-delta (SSOD). The method is based on forcing the system to enter into a limit cycle and on using the information achieved from the oscillation to estimate the transfer function parameters. By manipulating the PI controller, the system can reach different limit cycles as a consequence of the intersections of the Nyquist map of the process with the describing function reciprocal of the event-based sampler. The frequency and amplitude of the limit cycle selected to apply the method define the quality of the estimations, avoiding the inaccuracy that relay identification methods based on describing function produce. Simulation results demonstrate that the estimations can be as accurate as those obtained with relay identification methods for time-driven control systems based on other approaches (state-space, curve fitting, Laplace transform, etc.).

AB - This paper proposes an adaptive super-twisting decoupled terminal sliding mode control technique for a class of fourth-order systems. The adaptive-tuning law eliminates the requirement of the knowledge about the upper bounds of external perturbations. Using the proposed control procedure, the state variables of cart pole system are converged to decoupled terminal sliding surfaces and their equilibrium points in the finite time. Moreover, via the super-twisting algorithm, the chattering phenomenon is avoided without affecting the control performance. The numerical results demonstrate the high stabilization accuracy and lower performance indices values of the suggested method over the other ones. The simulation results on the cart-pole system as well as experimental validations demonstrate that the proposed control technique exhibits a reasonable performance in comparison with the other methods. PMID- 29455890 TI - Passivity analysis of memristor-based impulsive inertial neural networks with time-varying delays. AB - This paper focuses on delay-dependent passivity analysis for a class of memristive impulsive inertial neural networks with time-varying delays. By choosing proper variable transformation, the memristive inertial neural networks can be rewritten as first-order differential equations. The memristive model presented here is regarded as a switching system rather than employing the theory of differential inclusion and set-value map. Based on matrix inequality and Lyapunov-Krasovskii functional method, several delay-dependent passivity conditions are obtained to ascertain the passivity of the addressed networks. In addition, the results obtained here contain those on the passivity for the addressed networks without impulse effects as special cases and can also be generalized to other neural networks with more complex pulse interference. Finally, one numerical example is presented to show the validity of the obtained results. PMID- 29455891 TI - Multi-objective path planning for unmanned surface vehicle with currents effects. AB - This paper investigates the path planning problem for unmanned surface vehicle (USV), wherein the goal is to find the shortest, smoothest, most economical and safest path in the presence of obstacles and currents, which is subject to the collision avoidance, motion boundaries and velocity constraints. We formulate this problem as a multi-objective nonlinear optimization problem with generous constraints. Then, we propose the dynamic augmented multi-objective particle swarm optimization algorithm to achieve the solution. With our approach, USV can select the ideal path from the Pareto optimal paths set. Numerical simulations verify the effectiveness of our formulated model and proposed algorithm. PMID- 29455892 TI - Synchronization of heterogeneous linear networks with distinct inner coupling matrices. AB - In this paper, we study synchronization of heterogeneous linear networks with distinct inner coupling matrices. Firstly, for synchronous networks, we show that any synchronous trajectory will converge to a corresponding synchronous state. Then, we provide an invariant set, which can be exactly obtained by solving linear equations and then used for characterizing synchronous states. Afterwards, we use inner coupling matrices and node dynamics to successively decompose the original network into a new network, composed of the external part and the internal part. Moreover, this new network can be proved to synchronize to the above invariant set by constructing the corresponding desired Lyapunov-like functions for the internal part and the external part respectively. In particular, this result still holds if the coupling strength is disturbed slightly. Finally, examples with numerical simulations are given to illustrate the validity and applicability of our theoretical results. PMID- 29455893 TI - Cognitive Behavioural Therapy for Insomnia (CBT-I) to treat depression: A systematic review. AB - INTRODUCTION: Major depressive disorder is one of the most commonly diagnosed psychiatric illnesses, and it has a profound negative impact on an individual's ability to function. Up to 90% of individuals suffering from depression also report sleep and circadian disruptions. If these disruptions are not effectively resolved over the course of treatment, the likelihood of relapse into depression is greatly increased. Cognitive Behavioural Therapy for Insomnia (CBT-I) has shown promise in treating these sleep and circadian disturbances associated with depression, and may be effective as a stand-alone treatment for depression. This may be particularly relevant in cases where antidepressant medications are not ideal (e.g. due to contraindications, cost, or treatment resistance). METHODS: A systematic literature review was conducted of trials investigating the use of CBT I to treat depression in adults. Therapy included in-person CBT-I, as well as telehealth and group CBT-I. RESULTS AND CONCLUSIONS: CBT-I presents a promising treatment for depression comorbid with insomnia. In-person therapy has the most supporting evidence for its efficacy, though treatment effects may not be additive with those of antidepressant medications. Insomnia improvement due to CBT-I may mediate the improvement in depressive symptoms. There is less evidence for the use of telehealth, though a stepped-care approach is indicated based on baseline depressive severity. More research on group therapy and telehealth modalities of delivering CBT-I are required before making recommendations. PMID- 29455894 TI - Cognitive behavioural therapy for MS-related fatigue explained: A longitudinal mediation analysis. AB - BACKGROUND: Cognitive behavioural therapy (CBT) effectively reduces fatigue directly following treatment in patients with Multiple Sclerosis (MS), but little is known about the process of change during and after CBT. DESIGN: Additional analysis of a randomized clinical trial. OBJECTIVE: To investigate which psychological factors mediate change in fatigue during and after CBT. METHODS: TREFAMS-CBT studied the effectiveness of a 16-week CBT treatment for MS-related fatigue. Ninety-one patients were randomized (44 to CBT, 47 to the MS-nurse consultations). Mediation during CBT treatment was studied using assessments at baseline, 8 and 16weeks. Mediation of the change in fatigue from post-treatment to follow-up was studied separately using assessments at 16, 26 and 52weeks. Proposed mediators were: changes in illness cognitions, general self-efficacy, coping styles, daytime sleepiness, concentration and physical activity, fear of disease progression, fatigue perceptions, depression and physical functioning. Mediators were separately analysed according to the product-of-coefficients approach. Confidence intervals were calculated with a bootstrap procedure. RESULTS: During treatment the decrease in fatigue brought on by CBT was mediated by improved fatigue perceptions, increased physical activity, less sleepiness, less helplessness, and improved physical functioning. Post-treatment increases in fatigue levels were mediated by reduced physical activity, reduced concentration, and increased sleepiness. CONCLUSION: These results suggests that focusing on improving fatigue perceptions, perceived physical activity, daytime sleepiness, helplessness, and physical functioning may further improve the effectiveness of CBT for fatigue in patients with MS. Maintenance of treatment effects may be obtained by focusing on improving physical activity, concentration and sleepiness.

AB - AIMS: Psoriasis is a chronic inflammatory skin disease with a complex etiology, involving the immune system, genetic factors, and external/internal triggers, with psychosomatic aspects. The aim of the study was to investigate childhood trauma and resilience in a psoriatic sample compared with healthy controls. Correlations between childhood trauma, resilience, quality of life, clinical data and psoriatic features were also evaluated. METHODS: Seventy-seven psoriatic patients and seventy-six homogeneous healthy controls were enrolled. We used the Psoriasis Area and Severity Index (PASI) to assess the severity of psoriasis and the Skindex-29 to measure health-related quality of life. The psychometric battery included the Childhood Trauma Questionnaire (CTQ) and the Connor-Davidson Resilience Scale (CD-Risc) to assess trauma exposure and resilience, respectively. RESULTS: Psoriatic patients showed a significant prevalence of childhood trauma and a lower resilience level compared to healthy controls. Associations between traumatic experiences, low resilience and reduced quality of life in psoriatic subjects were also observed. CONCLUSIONS: A multidisciplinary approach is helpful to investigate clinical aspects, trigger factors and psychophysiological stress response in psoriatic subjects. Improving resilience with an early psychological intervention focused on self-motivation and strengthening of self-efficacy could facilitate the management of psoriasis. PMID- 29455896 TI - Layered stigma? Co-occurring depression and obesity in the public eye. AB - OBJECTIVES: Obesity and depression are common conditions in the general public and show a high level of co-morbidity. Both conditions are stigmatized, i.e., associated with negative attitudes and discrimination. Previous research shows that devalued conditions can overlap or combine to produce a layered stigma which is associated with more negative health outcomes than either single devalued condition alone. This study therefore set out to investigate the double stigma of obesity and depression. METHODS: A telephone-based representative study of the German population was conducted. Vignettes describing women with obesity, depression or both conditions were presented, followed by a set of items on semantic differentials based on previous stigma research of depression (depression stigma DS) and obesity (Fat Phobia Scale FPS). Personal experience with depression and obesity was assessed. RESULTS: All comparisons were significant in univariate ANOVA, showing negative attitudes measured by the FPS and the DS to be most pronounced in the double stigma condition. Multivariate analysis, controlling for age, gender, education and personal experience with the stigma condition (e.g. having obesity or depression), show that the double stigma obesity and depression is associated to more negative attitudes on the FPS (b=0.163, p<0.001) and the DS (b=0.154, p=0.002) compared to the single-stigma condition. CONCLUSIONS: The magnitude of the layered stigma of obesity and depression may need to be considered in mental health settings when treating the depressed patient with obesity, but likewise in obesity care when treating the obese patient with depression. PMID- 29455897 TI - Communal motivation in couples coping with vulvodynia: Sexual distress mediates associations with pain, depression, and anxiety. AB - OBJECTIVE: To examine the role of a novel motivational perspective-sexual communal motivation-in women's pain during intercourse and both partners' distress in couples coping with vulvodynia, a prevalent gynecological pain condition. Our goal was to test whether sexual communal strength (i.e., motivation to meet a partner's sexual needs) and unmitigated sexual communion (i.e., prioritization of a partner's sexual needs in neglect of one's own needs) were indirectly associated with pain, depression, and anxiety via sexual distress. METHODS: Couples (N=101) completed daily surveys about their sexual communal motivation, sexual distress, anxiety, depression, and women reported on their pain during intercourse. Using multilevel modeling, we examined how daily fluctuations in sexual communal motivation were directly and indirectly (via sexual distress) associated with pain and psychological distress. RESULTS: On days when women with vulvodynia reported higher sexual communal strength, they reported less pain and anxiety, and on days when they reported higher unmitigated sexual communion, they reported more pain, more anxiety, and both partners reported more depressive symptoms. Daily associations between women's unmitigated sexual communion and greater pain, depression and anxiety were mediated by sexual distress. CONCLUSIONS: Being motivated to meet a partner's sexual needs was associated with less pain and anxiety for women with vulvodynia, but when this motivation excluded a focus on one's own needs, there were detrimental consequences for women's pain and both partners' depressive symptoms. Interventions for improving women's pain and the psychological well-being of affected couples should target motivational factors and sexual distress.

The study aimed to (1) describe and categorise the content of the identified emotional talk, and (2) consider the evidence for an association of content with FCR trajectory. METHODS: A concurrent mixed methods approach was applied as part of a larger investigation (FORECAST) of breast cancer patients (n=87). Patients completed a daily diary during their radiotherapy treatment. Audio recordings were collected of review appointments. The Verona Coding Definitions of Emotional Sequences (VR-CoDES) system was used to code patient emotional cues and concerns (CCs). Purposeful sampling of the daily diary ratings identified 12 patients (30 consultations) with an increasing (n=6) or decreasing (n=6) FCR trajectory. The emotional talk of these patients at their weekly reviews was content analysed. RESULTS: Four themes were identified from 185 CCs: Physical Symptoms, Factors External to Hospital, Treatment, and Labelling Cancer. FCR decreasing trajectory group consultations were longer (p<0.02), expressed twice as many CCs as the increasing trajectory group (p<0.001), and were more likely to refer to cancer directly (p<0.05). CONCLUSIONS: The emotional content expressed matched features outlined in the Lee Jones et al. (1997) FCR model, and showed evidence of avoidance in increasing FCR trajectory patients.

The goals of this study were 1) to replicate these results in patients with fibromyalgia and/or chronic fatigue syndrome (CFS), and 2) to investigate predictors of distorted symptom perception within the patient group, with a focus on negative affectivity (NA), psychiatric comorbidity and somatic symptom severity. METHODS: Seventy-three patients diagnosed with fibromyalgia and/or CFS and 38 healthy controls (HC) completed a rebreathing paradigm, consisting of a baseline (60s of room air), a rebreathing phase (150s, gradually increasing ventilation, partial pressure of CO2 in the blood, and self-reported dyspnea), and a recovery phase (150s of room air). Dyspnea, respiratory flow and FetCO2 levels were measured continuously. RESULTS: Patients reported more dyspnea than HC in the recovery phase (p=0.039), but no differences between patients and HC were found in the baseline (p=0.07) or rebreathing phase (p=0.17). No significant differences between patients and HC were found in physiological reactivity. Within the patient group, the effect in the recovery phase was predicted by somatic symptom severity (p=0.046), but not by negative affectivity or by the number of psychiatric comorbidities. CONCLUSION: This study extended earlier findings in patients with medically unexplained dyspnea to patients with fibromyalgia and CFS. This suggests that altered symptom perception is a non symptom-specific mechanism underlying functional somatic syndromes in general, particularly in patients with high levels of somatic symptom severity. The results are discussed in a predictive coding framework of symptom perception. PMID- 29455900 TI - Heart rate variability is associated with psychosocial stress in distinct social domains. AB - OBJECTIVE: Psychosocial stress is associated with substantial morbidity and mortality. Accordingly, there is a growing interest in biomarkers that indicate whether individuals show adaptive (i.e., stress-buffering and health-promoting) or maladaptive (i.e., stress-escalating and health-impairing) stress reactions in social contexts. As heart rate variability (HRV) has been suggested to be a biomarker of adaptive behavior during social encounters, it may be possible that inter-individual differences in HRV are associated with inter-individual differences regarding stress in distinct social domains. METHODS: To test this hypothesis, resting state HRV and psychosocial stress was assessed in 83 healthy community-dwelling individuals (age: 18-35years). HRV was derived from heart rate recordings during spontaneous and instructed breathing to assess the robustness of possible associations between inter-individual differences in HRV and inter individual differences in psychosocial stress. Psychosocial stress was determined with a self-report questionnaire assessing stress in distinct social domains. RESULTS: A series of categorical and dimensional analyses revealed an association between inter-individual differences in HRV and inter-individual differences in psychosocial stress: Individuals with high HRV reported less stress in social life, but not in family life, work life or everyday life, than individuals with low HRV. CONCLUSIONS: On basis of these findings, it may be assumed that individuals with high HRV experience less psychosocial stress than individuals with low HRV. Although such an assumption needs to be corroborated by further findings, it seems to be consistent with previous findings showing that individuals with high HRV suffer less from stress and stress-related disorders than individuals with low HRV.

AB - AIMS: To examine prevalence, functioning and treatment associated with all DSM-5 12-month mood, anxiety, eating and substance use disorders among people with diabetes in data obtained from the National Epidemiologic Survey on Alcohol and Related Conditions-III. METHODS: Through multistage stratified randomized sampling a sample representative of the United States civilian population was obtained. Prevalence of diabetes (Type 1 and 2), DSM-5 disorders, physical and mental functioning, and treatment utilization were assessed via telephone interview. Analyses of weighted data (N=36,138) included calculation of descriptive statistics, and chi-square, logistic and linear regression analyses. RESULTS: Participants with (vs. without) diabetes (9.3% of weighted sample) had a significantly: (a) higher prevalence of any anxiety disorder and posttraumatic stress disorder (with and without adjustment for sociodemographic characteristics), and any mood disorder, major depressive disorder and specific phobia (with adjustment), (b) lower prevalence of any substance use disorder and alcohol and tobacco use disorders (with and without adjustment), and cannabis use disorder (without adjustment). Among participants with diabetes, mental disorder prevalence was consistently associated with sex and age, and to a lesser frequency, race/ethnicity. Lower levels of physical and mental functioning were found among participants with diabetes and a comorbid mental disorder. A minority of participants with diabetes and a comorbid mental disorder received treatment for mood and anxiety disorders, and few received treatment for eating and substance use disorders. CONCLUSIONS: Multiple types of mood, anxiety, eating and substance use disorders are prevalent, problematic, and often untreated among people with diabetes. PMID- 29455902 TI - Online social network response to studies on antidepressant use in pregnancy. AB - BACKGROUND: About 8% of U.S women are prescribed antidepressant medications around the time of pregnancy. Decisions about medication use in pregnancy can be swayed by the opinion of family, friends and online media, sometimes beyond the advice offered by healthcare providers. Exploration of the online social network response to research on antidepressant use in pregnancy could provide insight about how to optimize decision-making in this complex area. METHODS: For all 17 research articles published on the safety of antidepressant use in pregnancy in 2012, we sought to explore online social network activity regarding antidepressant use in pregnancy, via Twitter, in the 48h after a study was published, compared to the social network activity in the same period 1week prior to each article's publication. RESULTS: Online social network activity about antidepressants in pregnancy quickly doubled upon study publication. The increased activity was driven by studies demonstrating harm associated with antidepressants, lower-quality studies, and studies where abstracts presented relative versus absolute risks. IMPLICATIONS: These findings support a call for leadership from medical journals to consider how to best incentivize and support a balanced and clear translation of knowledge around antidepressant safety in pregnancy to their readership and the public. PMID- 29455903 TI - Gender differences in the relationship between workplace bullying and subjective back and neck pain: A two-wave study in a Norwegian probability sample. AB - OBJECTIVE: The association between exposure to bullying at work and subsequent pain reports is relatively well-established, but few studies have examined possible moderators of this relationship. As gender is a known risk factor for pain, with women reporting pain levels of higher intensity and longer duration, a possible gender difference in the relationship between bullying and pain has been suggested, but not sufficiently tested. The objective of the present study was therefore to examine whether gender moderates the prospective relationship between exposure to workplace bullying behaviours and subsequent subjective back and neck pain. METHODS: A national probability sample of Norwegian workers (N=1003) was collected at two time points with a six-month time-lag. Assumptions were tested using regression and moderation analyses. RESULTS: Exposure to bullying behaviours was associated with increased reports of subjective back and neck pain over time, and this relationship was moderated by gender. However, the interaction took a different form than expected, with back and neck pain increasing in response to bullying among men only, to a degree that nullified the baseline gender difference. CONCLUSION: The assumption that being female is a vulnerability factor for the development of pain in the aftermath of psychosocial stressors such as bullying was contradicted in the present study. Instead, women's relatively high baseline pain levels remain stable over time even after exposure to workplace bullying, while men's relatively low baseline pain levels increase in response to bullying, ultimately becoming tangent to the pain reported by women. PMID- 29455904 TI - Hypoglossal nerve paralysis in a child after a dental procedure. AB - Unilateral palsy of the hypoglossal nerve is a rare complication of orthodontic procedures. The main reported causes of HNP are: orthopedic and otorhinolaryngology surgical interventions, and in particular maneuvers involving compression or overstretching of the hypoglossal nerve, dental procedures and traumas, and also infections, motoneuron disorders, tumors, vascular diseases. Diagnosis is usually performed by electrophysiology studies (EMG-VCN), and brain magnetic resonance imaging (MRI) is useful to exclude other causes. The prognosis depends on the location and extension of the damage. Currently there is not a standardized treatment approach except the speech therapy, although, in some cases, the high-dose steroid treatment could be useful. We describe the case of a ten-year-old female, who was admitted in our Unit after a deviation of the tongue associated with dysarthria and dysphagia, occurred after the application of a mobile orthodontic device. PMID- 29455905 TI - Ventriculoperitoneal shunt treatment in a pregnant renal transplant recipient with idiopathic intracranial hypertension: Case report and review of the literature. AB - Idiopathic intracranial hypertension (IIH) is a relatively uncommon disorder characterised by raised intracranial pressure without an established pathogenesis. Diagnosis of IIH requires the demonstration of symptoms and signs referable only to elevated intracranial pressure; cerebrospinal fluid (CSF) opening pressure >25cm H2O measured in the lateral decubitus position; normal CSF composition; and no evidence for an underlying structural cause demonstrated by using MRI or contrast-enhanced CT scan for typical patients and MRI and MR venography for atypical patients such as man, children and those with low body mass index. We present a 38-year old primigravid renal transplant patient at 7 weeks of gestation who presented with 2 weeks of intense, throbbing, holocranial headache, nausea, vomiting, photophobia, diplopia and progressive visual loss. When medical treatment fails and/or not appropriate to use due to the reported of teratogenic risks in pregnant women, surgical interventions gain importance. In this particular patient, venticuloperitoneal shunt was chosen as the CSF diversion technique. In this case report indications, contraindications in addition to outcomes regarding headache, vision loss and the resolution of papilloedema of the present surgery options for IIH are discussed. PMID- 29455906 TI - Clinical analysis of combined revascularization in treating ischemic Moyamoya disease in adults. AB - OBJECTIVE: The aim of this study was to investigate the clinical efficacy of superficial temporal artery-middle cerebral artery anastomosis (STA MCA)+encephalo-duro-myo-synangiosis (EDMS) in treating ischemic Moyamoya disease (IMD) in adults. METHODS: A total of 30 adult patients with IMD were selected to be included in the study; they underwent STA-MCA+EDMS and were followed up for 3 months to 2 years. The digital subtraction angiography findings, modified Rankin scale (mRs) score, and complications of all the patients were compared. RESULTS: Thirty patients successfully completed the surgery. Three patients had postoperative complications (two patients with cerebral infarction on the surgical side and one patient with poor scalp healing). The postoperative morbidity rate was 10%. Angiography conducted at 3 to 6 months postoperatively showed 28 cases of anastomotic patency; the anastomotic patency rate was 93.3%. The mRs scores of the patients' neurological function 3 months after surgery were lower than those before surgery. CONCLUSION: STA-MCA+EDMS is effective in treating Moyamoya disease. PMID- 29455907 TI - Introduction to a Seminar on implementation and de-implementation to improve urologic cancer care. PMID- 29455908 TI - Increased degradation of ATP is driven by memory regulatory T cells in kidney transplantation tolerance. AB - Regulatory T cells were recently proposed as the central actor in operational tolerance after renal transplantation. Tolerant patients harbor increased FoxP3hi memory Treg frequency and increased demethylation in the Foxp3 Treg-specific demethylated region when compared to stable kidney recipients and exhibit greater memory Treg suppressive capacities and higher expression of the ectonucleotidase CD39. However, in this particular and unique situation the mechanisms of action of Tregs were not identified. Thus, we analyzed the ability of memory Tregs to degrade extracellular ATP in tolerant patients, healthy volunteers, and patients with stable graft function under immunosuppression and determined the role of immunosuppressive drugs on this process. The conserved proportion of memory Tregs leads to the establishment of a pro-tolerogenic balance in operationally tolerant patients. Memory Tregs in tolerant patients display normal capacity to degrade extracellular ATP/ADP. In contrast, memory Tregs from patients with stable graft function do not have this ability. Finally, in vitro, immunosuppressive drugs may favor the lower proportion of memory Tregs in stable patients, but they have no effect on CD39-dependent ATP degradation and do not explain memory Treg lack of extracellular ATP/ADP degradation ability. Thus, intrinsic active regulatory mechanisms may act long after immunosuppressive drug arrest in operationally tolerant patients and may contribute to kidney allograft tolerance via the maintenance of CD39 Treg function. PMID- 29455909 TI - Elevated tissue sodium deposition in patients with type 2 diabetes on hemodialysis detected by 23Na magnetic resonance imaging. AB - Long-term elevated blood sugar levels result in tissue matrix compositional changes in patients with diabetes mellitus type 2 (T2DM). We hypothesized that hemodialysis patients with T2DM might accumulate more tissue sodium than control hemodialysis patients. To test this, 23Na magnetic resonance imaging (23Na MRI) was used to estimate sodium in skin and muscle tissue in hemodialysis patients with or without T2DM. Muscle fat content was estimated by 1H MRI and tissue sodium content by 23Na MRI pre- and post-hemodialysis in ten hemodialysis patients with T2DM and in 30 matched control hemodialysis patients. We also assessed body fluid distribution with the Body Composition Monitor. 1H MRI indicated a tendency to higher muscle fat content in hemodialysis patients with T2DM compared to non-diabetic hemodialysis patients. 23Na MRI indicated increased sodium content in muscle and skin tissue of hemodialysis patients with T2DM compared to control hemodialysis patients. Multi-frequency bioimpedance was used to estimate extracellular water (ECW), and excess ECW in T2DM hemodialysis patients correlated with HbA1c levels. Sodium mobilization during hemodialysis lowered muscle sodium content post-dialysis to a greater degree in T2DM hemodialysis patients than in control hemodialysis patients. Thus, our findings provide evidence that increased sodium accumulation occurs in hemodialysis patients with T2DM and that impaired serum glucose metabolism is associated with disturbances in tissue sodium and water content. PMID- 29455910 TI - A public health needs assessment for domestic indoor overheating. AB - OBJECTIVES: Indoor overheating is a potentially fatal health hazard that was identified as an issue requiring urgent action in the 2017 UK Climate Change Risk Assessment. We aimed to make research on this issue more accessible to local public health teams to encourage its inclusion in local strategic needs assessments. STUDY DESIGN: Epidemiological health needs assessment. METHODS: We adapted established health needs assessment methods, focussing on the epidemiological component, drawing evidence from a non-systematic literature review that was complemented by discussion with experts. RESULTS: Indoor overheating arises from an interaction between occupants' susceptibility to heat, their behaviour and the building's location and its characteristics. Many of these factors are interrelated and, at a national level, are expected to vary over time with demographic and climate change. Understanding these factors, ways to mitigate them and a long-term view are all essential for managing overheating risk. CONCLUSIONS: There is a need for services to be provided at the local level that consider the home environment and its impact on health in all seasons. A population-level approach to risk management across a local area is also useful to inform collaborative efforts to reduce future incidence of overheating and better understand how it varies with socio-economic deprivation. PMID- 29455911 TI - Trauma theatre productivity - Does the individual surgeon, anaesthetist or consultant presence matter? AB - INTRODUCTION: With rising NHS clinical and financial demands, improving theatre efficiency is essential to maintain quality of patient care. Consistent teams and consultant presence have been shown to improve outcomes and productivity in elective orthopaedic surgery. The aim of this study was to investigate the impact on trauma theatre productivity of different surgeons and anaesthetists working together in a Major Trauma Centre. The influence of consultant presence and weekend operating on productivity was also considered. METHODS: Data relating to a single orthopaedic trauma theatre was gathered retrospectively for a two-year period. Variables including orthopaedic and anaesthetic consultant presence, number and complexity of operations performed and procedure start times were collected for daily trauma lists. Individual anaesthetic and orthopaedic consultants were compared by productivity outcomes. The impact of surgeons operating more frequently with one anaesthetist was also examined. RESULTS: Data relating to 2384 patients undergoing a total of 2787 procedures was collected. Orthopaedic consultant presence at the first surgical case (p < 0.05) and for 50% or greater of cases (p < 0.05) lead to higher mean number of cases performed per list and reduced turnaround time. Despite working with a significantly higher number of different consultant anaesthetists (p < 0.001) in year two, the productivity of surgeons as judged by list start time, total cases per list and total operating time was not significantly affected. Significantly earlier start times (p < 0.001) and shorter turnaround times (p < 0.001) at weekends led to maintained productivity despite shorter theatre time. No significant difference in productivity was found when comparing individual anaesthetic and orthopaedic consultants. Productivity was not significantly increased by surgeons operating more frequently with one individual anaesthetist. CONCLUSION: In the setting of an acute trauma theatre, orthopaedic consultant presence led to increased productivity. Furthermore, individual surgeon and anaesthetist pairings had no effect on overall productivity. Future efforts to improve productivity should focus on achieving earlier start times, consultant supervision of lists and reduced turnaround times between cases. PMID- 29455912 TI - Unperturbed, high spatial resolution measurement of Radon-222 in soil-gas depth profile. AB - This work presents a method for measuring the depth distribution of 222Rn activity in soil gas. The method is based on the capacity of polycarbonates to absorb 222Rn and on the possibility of performing sensitive measurements of 222Rn absorbed by the polycarbonates via liquid scintillation counting (LSC). The method is the following: cylindrical holes are drilled along a metal rod and Makrofol(r) N polycarbonate foils enclosed in polyethylene envelopes are placed in each hole. The rod is driven into the soil and kept for a certain time. As long as the rod is in the soil, the polycarbonate foils are exposed to the 222Rn concentration at their depth. At the end of the exposure the rod is pulled out and the foils are transferred to liquid scintillation (LS) vials filled with liquid scintillator. The 222Rn absorbed in the foils is then measured with a LS analyzer. The rod with the polycarbonate foils acts as a passive probe which senses the 222Rn concentration at different depths beneath the ground surface. The achievable minimum detectable 222Rn activity concentration with the equipment and conditions used in this study is around 12.5 kBq/m3. It can easily be lowered below 1 kBq/m3 if larger foils and low-background LS analyzers are used. Since the method does not require air sampling the depth distribution of 222Rn in the soil is unperturbed by the sampling. The spatial distribution and the maximum measurement depth are set by the distance between the holes and the depth to which the rod can be fixed into the ground. Results from in situ applications of the method in terrains with high 222Rn in soil-gas are reported, which demonstrate the feasibility and the usefulness of the proposed approach. PMID- 29455913 TI - Significant reduction in indoor radon in newly built houses. AB - Results from two national surveys of radon in newly built homes in Norway, performed in 2008 and 2016, were used in this study to investigate the effect of the 2010 building regulations introducing limit values on radon and requirements for radon prevention measures upon construction of new buildings. In both surveys, homes were randomly selected from the National Building Registry. The overall result was a considerable reduction of radon concentrations after the implementation of new regulations, but the results varied between the different dwelling categories. A statistically significant reduction was found for detached houses where the average radon concentration was almost halved from 76 to 40 Bq/m3. The fraction of detached houses which had at least one frequently occupied room with a radon concentration above the Action Level (100 Bq/m3) fell from 23.9% to 6.4%, while the fraction above the Upper Limit Value (200 Bq/m3) was reduced from 7.6% to 2.5%. In 2008 the average radon concentration measured in terraced and semi-detached houses was 44 and in 2016 it was 29 Bq/m3, but the reduction was not statistically significant. For multifamily houses, it was not possible to draw a conclusion due to insufficient number of measurements. PMID- 29455914 TI - Novel spectrometers for environmental dose rate monitoring. AB - A new generation of dosemeters, based on the scintillators LaBr3, CeBr3 and SrI2, read out with conventional photomultipliers, to be used in the field of environmental gamma-radiation monitoring, was investigated. The main features of these new instruments and especially their outdoor performance, studied by long term investigations under real weather conditions, are presented. The systems were tested at the reference sites for environmental radiation of the Physikalisch-Technische Bundesanstalt. The measurements are compared with that of well characterized classical dose rate reference instruments to demonstrate the suitability of new spectrometers for environmental dose rate monitoring even in adverse weather conditions. Their potential to replace the (mainly Geiger Muller based) dose rate meters operated in about 5000 European early waning network stations as well as in environmental radiation monitoring in general is shown. PMID- 29455915 TI - Fatty acid composition, enzyme activities and metallothioneins in Donax trunculus (Mollusca, Bivalvia) from polluted and reference sites in the Gulf of Annaba (Algeria): Pattern of recovery during transplantation. AB - The gulf of Annaba, the most important touristic and economic coastal zone located in Northeast Algeria, is contaminated by several pollutants from urban, agricultural, harbor and industrial activities. Elevated levels of heavy metals were detected in a locally prevalent edible mollusk Donax trunculus (Bivalvia, Donacidae) widely used as a sentinel species for the assessment of marine pollution. The present work aims to measure the difference between two localities, one being full of different pollutants (Sidi Salem) and the other being relatively clean (El Battah) and to evaluate the ability of D. trunculus to overcome the environmental stress during a transplantation experiment by a determination of fatty acid profile, the enzymes activities and the level of metallothioneins (MTs), a biomarker of metallic contamination. Adults of D. trunculus were collected at Sidi Salem (contaminated site) and transplanted into El Battah (reference site) for 21 days in cages (60 * 60 * 60 cm with a 2 mm mesh). Biochemical analyzes were conducted at different times (0, 7, 14 and 21 days). At 0-day experiment: the rate of the fatty acids, the enzymes activities and MT levels at the site of Sidi Salem (polluted site) were significantly different from those of El Battah. During the transplantation a gradual restoration of fatty acids rates, enzymes activities and MT levels was observed. At the end of the period of transplantation, the values are comparable to those of El Battah. A two-way ANOVA (time, site) on data revealed significant effects of time and site. Overally, D. trunculus is able to induce its detoxification system and to restore relatively rapidly the status of individuals from the reference site (El Battah). PMID- 29455916 TI - Mobilisation kinetics of hazardous elements in marine plastics subject to an avian physiologically-based extraction test. AB - Samples of plastic collected from two beaches in southwest England (n = 185) have been analysed by XRF spectrometry for elements that are hazardous or restricted in synthetic polymers (namely, As, Ba, Br, Cd, Cr, Hg, Pb, Sb and Se). Overall, one or more restricted element was detected in 151 samples, with 15 cases exhibiting non-compliance with respect to the Restriction of Hazardous Substances (RoHS) Directive. Twelve plastics that were RoHS-non-compliant were subsequently processed into microplastic-sized fragments and subjected to an avian physiologically-based extraction test (PBET) that simulates the chemical conditions in the gizzard-proventriculus of the northern fulmar. Kinetic profiles of metal and metalloid mobilisation in the PBET were fitted using a pseudo-first order diffusion model with rate constants ranging from ~0.02 to 0.5 h-1, while profiles for Br were better fitted with a parabolic diffusion model and rate constants of 7.4-9.5 (MUg L-1)-1h-1/2. Bioaccessibilities, based on maximum or equilibrium concentrations mobilised relative to total (XRF) concentrations, ranged from <1% for Cd and Se in polyethylene and polypropylene to over 10% for Br in a sample of expanded polystyrene and Pb in a sample of PVC. Calculations suggest that ingested plastic could contribute about 6% and 30% of a seabird's exposure to and accumulation of Pb and brominated compounds, respectively. PMID- 29455917 TI - Respiratory hazard assessment of combined exposure to complete gasoline exhaust and respirable volcanic ash in a multicellular human lung model at the air-liquid interface. AB - Communities resident in urban areas located near active volcanoes can experience volcanic ash exposures during, and following, an eruption, in addition to sustained exposures to high concentrations of anthropogenic air pollutants (e.g., vehicle exhaust emissions). Inhalation of anthropogenic pollution is known to cause the onset of, or exacerbate, respiratory and cardiovascular diseases. It is further postulated similar exposure to volcanic ash can also affect such disease states. Understanding of the impact of combined exposure of volcanic ash and anthropogenic pollution to human health, however, remains limited. The aim of this study was to assess the biological impact of combined exposure to respirable volcanic ash (from Soufriere Hills volcano (SHV), Montserrat and Chaiten volcano (ChV), Chile; representing different magmatic compositions and eruption styles) and freshly-generated complete exhaust from a gasoline vehicle. A multicellular human lung model (an epithelial cell-layer composed of A549 alveolar type II-like cells complemented with human blood monocyte-derived macrophages and dendritic cells cultured at the air-liquid interface) was exposed to diluted exhaust (1:10) continuously for 6 h, followed by immediate exposure to the ash as a dry powder (0.54 +/- 0.19 MUg/cm2 and 0.39 +/- 0.09 MUg/cm2 for SHV and ChV ash, respectively). After an 18 h incubation, cells were exposed again for 6 h to diluted exhaust, and a final 18 h incubation (at 37 degrees C and 5% CO2). Cell cultures were then assessed for cytotoxic, oxidative stress and (pro )inflammatory responses. Results indicate that, at all tested (sub-lethal) concentrations, co-exposures with both ash samples induced no significant expression of genes associated with oxidative stress (HMOX1, NQO1) or production of (pro-)inflammatory markers (IL-1beta, IL-8, TNF-alpha) at the gene and protein levels. In summary, considering the employed experimental conditions, combined exposure of volcanic ash and gasoline vehicle exhaust has a limited short-term biological impact to an advanced lung cell in vitro model. PMID- 29455918 TI - Consistent patterns of debris on South African beaches indicate that industrial pellets and other mesoplastic items mostly derive from local sources. AB - Identifying the sources of small plastic fragments is challenging because the original source item seldom can be identified. South Africa provides a useful model system to understand the factors influencing the distribution of beach litter because it has an open coastline with four equally-spaced urban-industrial centres distant from other major source areas. We sampled mesodebris (~2-25 mm) at 82 South African beaches in 1994, 2005 and 2015. Plastic items comprised 99% by number and 95% by mass of litter items. Industrial pellets were the most abundant plastic items, but fragments of rigid plastic items comprised most of the mass of debris. Strong correlations between industrial pellets and other plastic items indicate that common factors influence the distribution of both pellets and secondary mesoplastics. The abundance of mesodebris at beaches also was correlated in successive surveys, suggesting that beach-specific factors (e.g. aspect, slope, local currents, etc.) influence the amounts of debris on each beach. Sample year had no effect on mesodebris abundance, indicating that there has been little change in the amounts of mesodebris over the last two decades. There were consistently higher densities of both industrial pellets and other plastic items at beaches close to urban-industrial centres; there were only weak correlations with human population density and no correlation with local runoff. The size of industrial pellets decreased away from local urban centres, further supporting the conclusion that, like macroplastic litter, most mesoplastic pollution on continental beaches derives from local, land-based sources. This finding means that local actions to reduce plastics entering the sea will have local benefits, and that it may be possible to assess the efficacy of mitigation measures to reduce marine inputs of mesoplastic items. PMID- 29455919 TI - Satellite-based high-resolution PM2.5 estimation over the Beijing-Tianjin-Hebei region of China using an improved geographically and temporally weighted regression model. AB - Ground fine particulate matter (PM2.5) concentrations at high spatial resolution are substantially required for determining the population exposure to PM2.5 over densely populated urban areas. However, most studies for China have generated PM2.5 estimations at a coarse resolution (>=10 km) due to the limitation of satellite aerosol optical depth (AOD) product in spatial resolution. In this study, the 3 km AOD data fused using the Moderate Resolution Imaging Spectroradiometer (MODIS) Collection 6 AOD products were employed to estimate the ground PM2.5 concentrations over the Beijing-Tianjin-Hebei (BTH) region of China from January 2013 to December 2015. An improved geographically and temporally weighted regression (iGTWR) model incorporating seasonal characteristics within the data was developed, which achieved comparable performance to the standard GTWR model for the days with paired PM2.5- AOD samples (Cross-validation (CV) R2 = 0.82) and showed better predictive power for the days without PM2.5- AOD pairs (the R2 increased from 0.24 to 0.46 in CV). Both iGTWR and GTWR (CV R2 = 0.84) significantly outperformed the daily geographically weighted regression model (CV R2 = 0.66). Also, the fused 3 km AODs improved data availability and presented more spatial gradients, thereby enhancing model performance compared with the MODIS original 3/10 km AOD product. As a result, ground PM2.5 concentrations at higher resolution were well represented, allowing, e.g., short-term pollution events and long-term PM2.5 trend to be identified, which, in turn, indicated that concerns about air pollution in the BTH region are justified despite its decreasing trend from 2013 to 2015. PMID- 29455920 TI - Operating room traffic in total joint arthroplasty: Identifying patterns and training the team to keep the door shut. AB - BACKGROUND: Surgical site infections after joint arthroplasty are devastating complications and are influenced by patient, surgical, and operating room environmental factors. METHODS: In an effort to reduce the incidence of door openings (DOs) during total joint arthroplasty cases, this prospective observational study consisted of 3 phases. Phase 1 determined the baseline incidence of DOs, followed by installation of a mechanical door counter (phase 2). Finally, an educational seminar was presented to all personnel (phase 3) regarding the implications frequent DOs have on patient and surgical outcomes. RESULTS: The average openings per case (OPC) for each of the 3 phases were 33.5, 34.2, and 27.7, respectively. There was a 17% reduction in OPC between phases 1 and 3 (P= .02). There were no significant differences between knee and hip arthroplasty cases during the 3 phases (P= .21, P= .46, and P= .81, respectively). There was a strong correlation between length of surgery and OPC, with a Pearson coefficient of r = 0.87 during phase 3. To account for differences in average operative time between phases, data were normalized for the length of surgery with the ratio of door openings per minute determined (0.36, 0.34, and 0.32 for each phase, respectively). CONCLUSIONS: We were able to show that simply monitoring door openings during joint arthroplasty was not effective in reducing the occurrences. However, after a novel educational seminar given to all personnel, we were able to significantly reduce the incidence of operating room door openings, reducing a potential risk factor for surgical site infections. PMID- 29455921 TI - Clinical and epidemiological characteristics of intestinal parasite infection by Blastocystis hominis. AB - OBJECTIVES: Blastocystis hominis (B. hominis) is one of the most common intestinal parasites isolated in humans. The parasite can cause gastrointestinal symptoms or, in most cases, remain asymptomatic. There are issues concerning the parasite's pathogenic character. The aim of this study was to analyse the clinical and epidemiological characteristics of the parasite infection by B. hominis, with or without other parasitic co-infections. PATIENTS AND METHODS: An observational retrospective study was conducted of B. hominis isolates in faeces from October 2004 to March 2016 in a tropical medicine unit. We reviewed all patients with a parasite infection, exclusively or not by B. hominis. RESULTS: We studied 3070 patients, 570 (18%) of whom were diagnosed with B. hominis infection, which was the only isolate in 245 (43%) of the 570 patients. A total of 325 (57%) patients presented other parasitic co-infections (Entamoeba histolytic or Entamoeba dispar, Strongyloides stercoralis, hookworm and Schistosoma spp.). The main symptom was abdominal pain (41.8%). In 31.2% of cases, the parasite was detected in the imported diseases screening of asymptomatic patients. Of those who underwent treatment with metronidazole, 78.2% improved. The parasite was neutralised in 82.6% of the patients. CONCLUSIONS: Parasite infection by B. hominis is one of the most common diseases in our tropical medicine unit. Most patients are asymptomatic, or their symptoms can be attributed to other parasite infections. In those cases in which symptoms persist without being able to attribute them to other causes, a specific treatment is recommended.

AB - BACKGROUND: A growing number of studies have addressed the long-term consequences of intensive care unit (ICU) treatment, but few have studied the prevalence of chronic pain and pain characteristics longitudinally. AIMS: The goal of the work described here was to investigate the prevalence and characteristics of chronic pain in ICU survivors 3 months and 1 year after ICU discharge and to identify risk factors for chronic pain 1 year after ICU discharge. DESIGN: The design used was an explorative and longitudinal study. SETTING/PATIENTS: The patients in this work had stayed >48 hours in two mixed ICUs in Oslo University Hospital, a tertiary referral hospital. METHODS: Patients completed a survey questionnaire 3 months and 1 year after ICU discharge. Pain was assessed using the Brief Pain Inventory-Short Form. RESULTS: At 3 months after discharge, 58 of 118 ICU survivors (49.2%) reported pain, and at 1 year after discharge, 34 of 89 survivors (38.2%) reported pain. The most common sites of pain at 3 months were the shoulder and abdomen; the shoulder remained the second most common site at 1 year. There was an increase in the interference of pain with daily life at 1 year. Possible risk factors for chronic pain at 1 year were increased severity of illness, organ failure, ventilator time >12 days, and ICU length of stay >15 days. The most common sites of pain were not linked to the admission diagnosis. CONCLUSIONS: These findings may enable health care providers to improve care and rehabilitation for this patient group. PMID- 29455924 TI - GEC-ESTRO ACROP recommendations in skin brachytherapy. AB - PURPOSE: The aim of this publication is to compile available literature data and expert experience regarding skin brachytherapy (BT) in order to produce general recommendations on behalf of the GEC-ESTRO Group. METHODS: We have done an exhaustive review of published articles to look for general recommendations. RESULTS: Randomized controlled trials, systemic reviews and meta-analysis are lacking in literature and there is wide variety of prescription techniques successfully used across the radiotherapy centers. BT can be delivered as superficial application (also called contact BT or plesiotherapy) or as interstitial for tumours thicker than 5 mm within any surface, including very irregular. In selected cases, particularly in tumours located within curved surfaces, BT can be advantageous modality from dosimetric and planning point of view when compared to external beam radiotherapy. The general rule in skin BT is that the smaller the target volume, the highest dose per fraction and the shortest overall length of treatment can be used. CONCLUSION: Skin cancer incidence is rising worldwide. BT offers an effective non-invasive or minimally invasive and relative short treatment that particularly appeals to elder and frail population. PMID- 29455925 TI - Differentiation of remitting neuromyelitis optica spectrum disorders from multiple sclerosis by integrating parameters from serum proteins and lymphocyte subsets. AB - Differential diagnosis for neuromyelitis optica spectrum disorder (NMOSD) and multiple sclerosis (MS) is always doubtful. To differentiate these diseases, we studied the immune status in the blood of patients with MS (n = 45) or NMOSD (n = 23) at remission phase. Remitting NMOSD patients had increased levels of CXCL13 and memory B cells, while remitting MS patients had elevated levels of galectin-9 and Th1 cells. A diagnostic model with these four variables is built to distinguish remitting NMOSD from MS with a sensitivity of 91.30%. Our diagnostic model may help to improve the differentiation of remitting NMOSD from MS. PMID- 29455926 TI - Unravelling salutogenic mechanisms in the workplace: the role of learning. AB - OBJECTIVE: To explore the moderating and mediating role(s) of learning within the relationship between sense of coherence (SOC) and generalized resistance resources. METHOD: Cross-sectional study (N=481), using a self-administered questionnaire, of employees working in the healthcare sector in the Netherlands in 2017. Four residential healthcare settings and one healthcare-related Facebook group were involved. Multiple linear regression models were used to test for moderating and mediating effects of learning. RESULTS: Social relations, task significance, and job control significantly explained variance in SOC. Conceptual, social, and instrumental learning, combined, moderated the relationship between SOC and task significance. Instrumental learning moderated the relationship between job control and SOC. Social learning also mediated this relationship. Conceptual learning did not show any moderating or mediating effect. CONCLUSIONS: The relationship between SOC and the three GRRs seems to be strengthened or explained-to a certain extent-by instrumental and social learning. Healthcare organizations are recommended to promote learning through formal activities as well as through cooperation, feedback, sharing experiences, and job challenges. This requires employee participation and a multilevel interdisciplinary approach. PMID- 29455927 TI - Fibroblast Heterogeneity and Immunosuppressive Environment in Human Breast Cancer. AB - Carcinoma-associated fibroblasts (CAF) are key players in the tumor microenvironment. Here, we characterize four CAF subsets in breast cancer with distinct properties and levels of activation. Two myofibroblastic subsets (CAF S1, CAF-S4) accumulate differentially in triple-negative breast cancers (TNBC). CAF-S1 fibroblasts promote an immunosuppressive environment through a multi-step mechanism. By secreting CXCL12, CAF-S1 attracts CD4+CD25+ T lymphocytes and retains them by OX40L, PD-L2, and JAM2. Moreover, CAF-S1 increases T lymphocyte survival and promotes their differentiation into CD25HighFOXP3High, through B7H3, CD73, and DPP4. Finally, in contrast to CAF-S4, CAF-S1 enhances the regulatory T cell capacity to inhibit T effector proliferation. These data are consistent with FOXP3+ T lymphocyte accumulation in CAF-S1-enriched TNBC and show how a CAF subset contributes to immunosuppression.

AB - Aerobic glycolysis (the Warburg effect) facilitates tumor growth, and drugs targeting aerobic glycolysis are being developed. However, how the Warburg effect is directly regulated is largely unknown. Here we show that transcription factor SIX1 directly increases the expression of many glycolytic genes, promoting the Warburg effect and tumor growth in vitro and in vivo. SIX1 regulates glycolysis through HBO1 and AIB1 histone acetyltransferases. Cancer-related SIX1 mutation increases its ability to promote aerobic glycolysis and tumor growth. SIX1 glycolytic function is directly repressed by microRNA-548a-3p, which is downregulated, inversely correlates with SIX1, and is a good predictor of prognosis in breast cancer patients. Thus, the microRNA-548a-3p/SIX1 axis strongly links aerobic glycolysis to carcinogenesis and may become a promising cancer therapeutic target.

AB - Beta-thalassaemia causes defective haemoglobin synthesis leading to ineffective erythropoiesis, chronic haemolytic anaemia, and subsequent clinical complications. Blood transfusion and iron chelation allow long-term disease control, and haematopoietic stem cell transplantation offers a potential cure for some patients. Nonetheless, there are still many challenges in the management of beta-thalassaemia. The main treatment option for most patients is supportive care; furthermore, the long-term efficacy and safety of current therapeutic strategies are limited and adherence is suboptimal. An increasing understanding of the underlying molecular and cellular disease mechanisms plus an awareness of limitations of current management strategies are driving research into novel therapeutic options. Here we provide an overview of the current pathophysiology, clinical manifestations, and global burden of beta-thalassaemia. We reflect on what has been achieved to date, describe the challenges associated with currently available therapy, and discuss how these issues might be addressed by novel therapeutic approaches in development.

AB - In light of extensive urbanization and deforestation, toxic wastes are being released into the atmosphere, causing increased air and soil pollution. Conventional methods of soil remediation are time consuming and labor and cost intensive, rendering them uneconomical to maintain sustainable agriculture. One solution is to use natural resources like plants and microbes for phytoremediation. A thorough systemic knowledge of plant-microbe interactions will allow the use of gene editing and gene manipulation techniques to increase the efficiency of plants in phytoremediation. This Opinion article focuses on gene editing techniques used in plants and microbes for phytoremediation and also emphasizes their effectiveness, advancement, and future implications for sustainable and environmentally friendly agriculture. PMID- 29455936 TI - Engineering a Clinically Translatable Bioartificial Pancreas to Treat Type I Diabetes. AB - Encapsulating, or immunoisolating, insulin-secreting cells within implantable, semipermeable membranes is an emerging treatment for type 1 diabetes. This approach can eliminate the need for immunosuppressive drug treatments to prevent transplant rejection and overcome the shortage of donor tissues by utilizing cells derived from allogeneic or xenogeneic sources. Encapsulation device designs are being optimized alongside the development of clinically viable, replenishable, insulin-producing stem cells, for the first time creating the possibility of widespread therapeutic use of this technology. Here, we highlight the status of the most advanced and widely explored implementations of cell encapsulation with an eye toward translating the potential of this technological approach to medical reality. PMID- 29455937 TI - The Impact of Patient and Surgical Factors on the Rate of Postoperative Infection After Total Hip Arthroplasty-A New Zealand Joint Registry Study. AB - BACKGROUND: Periprosthetic joint infection (PJI) is a devastating complication after total hip arthroplasty (THA). The potential to define and modify risk factors for infection represents an important opportunity to reduce the incidence of PJI. This study uses New Zealand Joint Registry data to identify independent risk factors associated with PJI after primary THA. METHODS: Data on 91,585 THAs performed between 2000 and 2014 were analyzed. Factors associated with revision for PJI within 12 months were identified using univariate and multivariate analyses. RESULTS: Revision rates for PJI were 0.15% and 0.21% at 6 and 12 months, respectively. Multivariate analysis showed significant associations with the American Society of Anesthesiologists grade (odds ratio [OR] 6.13, 95% confidence interval [CI] 1.28-29.39), severe or morbid obesity (OR 2.15, CI 1.01 4.60 and OR 3.73, CI 1.49-9.39), laminar flow ventilation (OR 1.98, CI 1.38 2.85), consultant-supervised trainee operations (OR 1.94, CI 1.22-3.08), male gender (OR 1.68, CI 1.23-2.30) and anterolateral approach (OR 1.62, CI 1.11 2.37). Procedures performed in the private sector were protective for revision for infection (OR 0.68, CI 0.48-0.96). CONCLUSIONS: The PJI risk profile for patients undergoing THA is constituted of a complex of patient and surgical factors. Several patient factors had strong independent associations with revision rates for PJI. Although surgical factors were less important, these may be more readily modifiable in practice. PMID- 29455938 TI - Comparison of Periarticular Local Infiltration Analgesia With Femoral Nerve Block for Total Knee Arthroplasty: a Meta-Analysis of Randomized Controlled Trials. AB - BACKGROUND: Total knee arthroplasty (TKA) is accompanied by moderate-to-severe postoperative pain. Postoperative pain will hamper functional recovery and lower patients' satisfaction with surgery. Recently, periarticular local infiltration analgesia (LIA) has been widely used in TKA. However, there is no definite answer as to the efficacy and safety of LIA compared with femoral nerve block (FNB). METHOD: Randomized controlled trials about relevant studies were searched from PubMed (1996 to July 2017), Embase (1980 to July 2017), and Cochrane Library (CENTRAL, July 2017). Ten studies which compared LIA with FNB methods were included in our meta-analysis. RESULTS: Ten studies containing 950 patients met the inclusion criteria. Our pooled data indicated that LIA was as effective as the FNB in terms of visual analog scale score for pain at 24 hours (P = .52), 48 hours (P = .36), and 72 hours (P = .27), and total morphine consumption (P = .27), range of motion (P = .45), knee society score (P = .51), complications (P = .81), and length of hospital stay (P = .75). CONCLUSIONS: Our current meta analysis results demonstrated that there were no differences in efficacy between the FNB and LIA method.

PMID- 29455939 TI - Strategies to facilitate shared decision-making about pediatric oncology clinical trial enrollment: A systematic review. AB - OBJECTIVE: We conducted a systematic review to identify the strategies that have been recommended in the literature to facilitate shared decision-making regarding enrolment in pediatric oncology clinical trials. METHODS: We searched seven databases for peer-reviewed literature, published 1990-2017. Of 924 articles identified, 17 studies were eligible for the review. We assessed study quality using the 'Mixed-Methods Appraisal Tool'. We coded the results and discussions of papers line-by-line using nVivo software. We categorized strategies thematically. RESULTS: Five main themes emerged: 1) decision-making as a process, 2) individuality of the process; 3) information provision, 4) the role of communication, or 5) decision and psychosocial support. Families should have adequate time to make a decision. HCPs should elicit parents' and patients' preferences for level of information and decision involvement. Information should be clear and provided in multiple modalities. Articles also recommended providing training for healthcare professionals and access to psychosocial support for families. CONCLUSION: High quality, individually-tailored information, open communication and psychosocial support appear vital in supporting decision-making regarding enrollment in clinical trials. These data will usefully inform future decision-making interventions/tools to support families making clinical trial decisions. PRACTICE IMPLICATIONS: A solid evidence-base for effective strategies which facilitate shared decision-making is needed. PMID- 29455941 TI - ? PMID- 29455943 TI - ? PMID- 29455942 TI - ?

PMID- 29455946 TI - Abstract semantics in the motor system? - An event-related fMRI study on passive reading of semantic word categories carrying abstract emotional and mental meaning. AB - Previous research showed that modality-preferential sensorimotor areas are relevant for processing concrete words used to speak about actions. However, whether modality-preferential areas also play a role for abstract words is still under debate. Whereas recent functional magnetic resonance imaging (fMRI) studies suggest an involvement of motor cortex in processing the meaning of abstract emotion words as, for example, 'love', other non-emotional abstract words, in particular 'mental words', such as 'thought' or 'logic', are believed to engage 'amodal' semantic systems only. In the present event-related fMRI experiment, subjects passively read abstract emotional and mental nouns along with concrete action related words. Contrary to expectation, the results indicate a specific involvement of face motor areas in the processing of mental nouns, resembling that seen for face related action words. This result was confirmed when subject specific regions of interest (ROIs) defined by motor localizers were used. We conclude that a role of motor systems in semantic processing is not restricted to concrete words but extends to at least some abstract mental symbols previously thought to be entirely 'disembodied' and divorced from semantically related sensorimotor processing. Implications for neurocognitive theories of semantics and clinical applications will be highlighted, paying specific attention to the role of brain activations as indexes of cognitive processes and their relationships to 'causal' studies addressing lesion and transcranial magnetic stimulation (TMS) effects. Possible implications for clinical practice, in particular speech language therapy, are discussed in closing. PMID- 29455947 TI - The neural exploitation hypothesis and its implications for an embodied approach to language and cognition: Insights from the study of action verbs processing and motor disorders in Parkinson's disease. AB - As it is widely known, Parkinson's disease is clinically characterized by motor disorders such as the loss of voluntary movement control, including resting tremor, postural instability, and bradykinesia (Bocanegra et al., 2015; Helmich, Hallett, Deuschl, Toni, & Bloem, 2012; Liu et al., 2006; Rosin, Topka, & Dichgans, 1997). In the last years, many empirical studies (e.g., Bocanegra et al., 2015; Spadacenta et al., 2012) have also shown that the processing of action verbs is selectively impaired in patients affected by this neurodegenerative disorder. In the light of these findings, it has been suggested that Parkinson disorder can be interpreted within an embodied cognition framework (e.g., Bocanegra et al., 2015). The central tenet of any embodied approach to language and cognition is that high order cognitive functions are grounded in the sensory motor system. With regard to this point, Gallese (2008) proposed the neural exploitation hypothesis to account for, at the phylogenetic level, how key aspects of human language are underpinned by brain mechanisms originally evolved for sensory-motor integration. Glenberg and Gallese (2012) also applied the neural exploitation hypothesis to the ontogenetic level. On the basis of these premises, they developed a theory of language acquisition according to which, sensory-motor mechanisms provide a neurofunctional architecture for the acquisition of language, while retaining their original functions as well. The neural exploitation hypothesis is here applied to interpret the profile of patients affected by Parkinson's disease. It is suggested that action semantic impairments directly tap onto motor disorders. Finally, a discussion of what theory of language is needed to account for the interactions between language and movement disorders is presented. PMID- 29455948 TI - Belief, delusion, hypnosis, and the right dorsolateral prefrontal cortex: A transcranial magnetic stimulation study. AB - According to the Two-Factor theory of delusional belief (see e.g. Coltheart at al., 2011), there exists a cognitive system dedicated to the generation, evaluation, and acceptance or rejection of beliefs. Studies of the neuropsychology of delusion provide evidence that this system is neurally realized in right dorsolateral prefrontal cortex (rDLPFC). Furthermore, we have shown that convincing analogues of many specific delusional beliefs can be created in nonclinical subjects by hypnotic suggestion and we think of hypnosis as having the effect of temporarily interfering with the operation of the belief system, which allows acceptance of the delusional suggestions. If the belief system does depend on rDLPFC, then disrupting the activity of that region of the brain by the application of repetitive transcranial magnetic stimulation (rTMS) will increase hypnotizability. Dienes and Hutton (2013) have reported such an experiment except that it was left DLPFC to which rTMS was applied. An effect on a subjective measure of hypnotizability was observed, but whether there was an effect on an objective measure could not be determined. We report two experiments. The first was an exact replication of the Dienes and Hutton experiment; here we found no effect of rTMS to lDLPFC on any hypnotic measure. Our second experiment used rTMS applied to right rather then left DLPFC. This right-sided stimulation enhanced hypnotizability (when hypnotic response was measured objectively), as predicted by our hypothesis. These results imply a role for rDLPFC in the cognitive process of belief evaluation, as is proposed in our two-factor theory of delusion. They are also consistent with a conception of the acceptance of a hypnotic suggestion as involving suspension of disbelief.

AB - Atrial fibrillation (AF) is a chronic progressive disease characterized by exacerbations and remissions. It remains the most common sustained arrhythmia seen in clinical practice, and represents a major burden to health care systems. Similar to other cardiovascular conditions, significant sex-specific differences have been observed in the epidemiology (lower rate of prevalence in women, women present at a later age), pathophysiology (sex-related differences in AF triggers and substrate), clinical presentation (women are more likely symptomatic, with relatively more severe symptoms), and natural history. Moreover, similar to other cardiovascular conditions there are substantial sex-specific differences in the management of AF, with women being significantly less likely to receive therapeutic anticoagulation, attempts at rhythm control, or undergo invasive cardiovascular procedures. The purpose of this review is to explore these sex specific differences.

PMID- 29455951 TI - Sex Hormone Contributes to Sexually Dimorphic Susceptibility in CVB3-Induced Viral Myocarditis via Modulating IFN-gamma+ NK Cell Production. AB - BACKGROUND: Viral myocarditis is a widespread cardiac disease associated with inflammation and myocardial injury and is predominantly caused by coxsackievirus B3 (CVB3) infection in humans as well as in mice. CVB3-induced myocarditis shows sexually dimorphic sensitivity and is more prevalent in male mice. Our previous studies showed that natural killer (NK) cells played an indispensable role in CVB3-induced myocarditis, and female mice exhibited less pathological cardiac interferon gamma (IFN-gamma)+ NK cell infiltration than did male mice. However, the precise mechanisms were not well elucidated. METHODS: We investigated the influence of estrogen on cardiac IFN-gamma+ NK cell enrichment in CVB3-induced myocarditis and explored the underlying molecular mechanism. RESULTS: In this study, we found that CVB3 stimulation could clearly induce IFN-gamma expression by NK cells; however, this trend could be blunted by estrogen treatment. Consistently, ovariectomized female mice with decreased estrogen levels exhibited substantially increased enrichment of cardiac IFN-gamma+ NK cells and displayed significantly aggravated myocarditis. Similarly, estrogen-treated male mice showed less cardiac IFN-gamma+ NK cell infiltration, accompanied by significantly alleviated viral myocarditis. In sharp contrast, sexually immature female and male mice (with similar estrogen levels) showed comparable levels of cardiac IFN gamma+ NK cell infiltration and similar levels of myocarditis severity. Upon further exploration of the underlying mechanisms, we found that estrogen could downregulate expression of Th1-specific T box transcription factor (T-bet), the key transcription factor associated with IFN-gamma production, in CVB3-stimulated NK cells. CONCLUSIONS: Overall, this study might help us understand the mechanism of increased cardiac infiltration by IFN-gamma+ NK cells in CVB3-infected male mice compared with that in female mice and might provide new clues for the sex bias in CVB3-induced myocarditis. PMID- 29455953 TI - The comprehensive characterization of adrenocortical steroidogenesis using two dimensional ultra-performance liquid chromatography - electrospray ionization tandem mass spectrometry. AB - The perturbation of the homeostasis of adrenocortical steroids plays a fundamental role in several pathological conditions. Currently, only a few of the substances involved in steroidogenesis are routinely analysed in clinical laboratories for the diagnosis of these conditions. Recently, interest has grown over the development of clinical assays of endogenous steroids using liquid chromatography-tandem mass spectrometry (LC-MS/MS). However, no approaches have assessed the adrenocortical steroidogenesis comprehensively. Here, a novel LC MS/MS assay is presented for evaluating the serum levels of all respective major substances (aldosterone, androstenedione, dehydroepiandrosterone, dehydroepiandrosterone sulfate, 11-deoxycorticosterone, 11-deoxycortisol, 21 deoxycortisol, dihydrotestosterone, 17alpha-hydroxypregnenolone, 17alpha hydroxyprogesterone, corticosterone, cortisol, cortisone, pregnenolone, progesterone and testosterone). The analysis time was 5.5 min following highly efficient solid phase extraction conducted on a novel polymer phase with N polyvinylpyrrolidine branches. The method was validated in accordance with the respective guideline of the European Medicines Agency. The cross-validation of 8 analytes with immunoassays was also accomplished. Two-dimensional chromatography allowed the elution of the 16 analytes between 2.3-4.6 min and with a sufficient resolution of isobaric compounds. Quantitation was performed throughout the clinically relevant concentration ranges. Within-run accuracy was 87.1-115%, 90.0 109%, 87.2-111% and 87.6-107% at spiking levels 1 thru 4, while the precision was 4.7-27.9%, 2.9-17.7%, 5.6-13.9% and 1.9-15.0%, respectively. Between-run accuracy was 81.0-119.5, 85.2-113, 87.4-113 and 93.1-113%, respectively, while the precision was 3.4-13.5%, 2.0-10.2%, 2.1-15.0%, and 1.5-6.6%, respectively. In cross-validation studies, the mean percentage differences ranged between -51.4% (dehydroepiandrosterone sulfate) and 17.5% (dehydroepiandrosterone). The approach allows the comprehensive characterization of the adrenocortical steroid homeostasis in clinical diagnostics. PMID- 29455955 TI - To med(iastinoscopy) or not to med(iastinoscopy).

PMID- 29455954 TI - The Peroxisome Proliferator-Activated Receptor alpha is dispensable for cold induced adipose tissue browning in mice. AB - OBJECTIVE: Chronic cold exposure causes white adipose tissue (WAT) to adopt features of brown adipose tissue (BAT), a process known as browning. Previous studies have hinted at a possible role for the transcription factor Peroxisome Proliferator-Activated Receptor alpha (PPARalpha) in cold-induced browning. Here we aimed to investigate the importance of PPARalpha in driving transcriptional changes during cold-induced browning in mice. METHODS: Male wildtype and PPARalpha-/- mice were housed at thermoneutrality (28 degrees C) or cold (5 degrees C) for 10 days. Whole genome expression analysis was performed on inguinal WAT. In addition, other analyses were carried out. Whole genome expression data of livers of wildtype and PPARalpha-/- mice fasted for 24 h served as positive control for PPARalpha-dependent gene regulation. RESULTS: Cold exposure increased food intake and decreased weight of BAT and WAT to a similar extent in wildtype and PPARalpha-/- mice. Except for plasma non-esterified fatty acids, none of the cold-induced changes in plasma metabolites were dependent on PPARalpha genotype. Histological analysis of inguinal WAT showed clear browning upon cold exposure but did not reveal any morphological differences between wildtype and PPARalpha-/- mice. Transcriptomics analysis of inguinal WAT showed a marked effect of cold on overall gene expression, as revealed by principle component analysis and hierarchical clustering. However, wildtype and PPARalpha-/ mice clustered together, even after cold exposure, indicating a similar overall gene expression profile in the two genotypes. Pathway analysis revealed that cold upregulated pathways involved in energy usage, oxidative phosphorylation, and fatty acid beta-oxidation to a similar extent in wildtype and PPARalpha-/- mice. Furthermore, cold-mediated induction of genes related to thermogenesis such as Ucp1, Elovl3, Cox7a1, Cox8, and Cidea, as well as many PPAR target genes, was similar in wildtype and PPARalpha-/- mice. Finally, pharmacological PPARalpha activation had a minimal effect on expression of cold-induced genes in murine WAT. CONCLUSION: Cold-induced changes in gene expression in inguinal WAT are unaltered in mice lacking PPARalpha, indicating that PPARalpha is dispensable for cold-induced browning.

PMID- 29455958 TI - Esophagectomy versus endoscopic resection for patients with early-stage esophageal adenocarcinoma: A National Cancer Database propensity-matched study. AB - OBJECTIVES: Endoscopic resection has been rapidly adopted in the treatment of early-stage esophageal tumors. We compared the outcomes after esophagectomy or endoscopic resection for stage T1a adenocarcinoma. METHODS: We queried the National Cancer Database for patients with T1a esophageal adenocarcinoma who underwent esophagectomy or endoscopic resection and generated a balanced cohort with 735 matched pairs using propensity-score matching. We then performed a multivariable Cox regression analysis on the matched and unmatched cohorts. RESULTS: We identified 2173 patients; 1317 (60.6%) underwent esophagectomy, and 856 (39.4%) underwent endoscopic resection. In the unmatched cohort, patients who underwent esophagectomy were younger, more often not treated in academic settings, and more likely to have comorbidities (30.4% vs 22.5%, P = .002). They had longer hospital stays and more readmissions than patients who underwent endoscopic resection. Factors positively affecting overall survival were younger age, resection at an academic medical center, and lower Charlson-Deyo comorbidity score. In the matched cohort, patients who underwent esophagectomy had longer hospital stays and were more likely to be readmitted within 30 days (7.0% vs 0.6%, P < .001). When a time period-specific partition was applied, endoscopic resection had a lower death hazard 0 to 90 days after resection (hazard ratio, 0.15; P = .003), but this was reversed for survival greater than 90 days (hazard ratio, 1.34; P = .02). CONCLUSIONS: In patients with early-stage esophageal adenocarcinoma, survival appears equivalent after endoscopic resection or esophagectomy, but endoscopic resection is associated with shorter hospital stays, fewer readmissions, and less 90-day mortality. In patients surviving more than 90 days, esophagectomy may provide better overall survival. PMID- 29455959 TI - Discussion.

PMID- 29455962 TI - Needle localization of small pulmonary nodules: Lessons learned. AB - BACKGROUND: Lung nodules that are small and deep within lung parenchyma, and have semisolid characteristics are often challenging to localize with video-assisted thoracoscopic surgery (VATS). We describe our cumulative experience using needle localization of small nodules before surgical resection. We report procedural tips, operative results, and lessons learned over time. METHODS: A retrospective review of all needle localization cases between July 1, 2006, and December 30, 2016, at a single institution was performed. A total of 253 patients who underwent needle localization of lung nodules ranging from 0.6 to 1.2 cm before operation were enrolled. Nodules were localized by placing two 20-gauge Hawkins III coaxial needles from different trajectories with tips adjacent to the nodule, injection of 0.3 to 0.6 mL of methylene blue, and deployment of 2 hookwires, under computed tomography guidance. Patients then underwent VATS wedge resection for diagnosis, followed by anatomic resection for lung carcinoma. Procedural and perioperative outcomes were assessed. RESULTS: Needle localization was successful in 245 patients (96.8%). Failures included both wires falling out of lung parenchyma before operation (5 patients), wire migration (2 patients), and bleeding resulting in hematoma requiring transfusion (1 patient). The most common complication of needle localization was asymptomatic pneumothorax (11/253 total patients; 4.3%) and was higher in patients with bullous emphysema (9/35 patients; 25.7%). Of the 8 individuals who had unsuccessful needle localization, 7 had successful wedge resection in the area of methylene blue injection that included the nodule; 1 required segmentectomy for diagnosis. Completion lobectomy (154 VATS, 2 minithoracotomies) or VATS segmentectomy (18 patients) was performed in 174 individuals with a diagnosis of non-small cell carcinoma or carcinoid. The average length of hospital stay was 1.4 days for wedge resection, 1.9 days for VATS segmentectomy, 3.1 days for VATS lobectomy, and 4.9 days for minithoracotomy. Perioperative survival was 100%. CONCLUSIONS: Needle localization with hookwire deployment and methylene blue injection is a safe and feasible strategy to localize small, deep lung nodules for wedge resection and diagnosis. Multidisciplinary coordination between the thoracic surgeon and the interventional radiologist is key to the success of this procedure. PMID- 29455963 TI - Discussion. PMID- 29455964 TI - Polytetrafluoroethylene conduits versus homografts for right ventricular outflow tract reconstruction in infants and young children: An institutional experience. AB - OBJECTIVE: Our institution uses a valved polytetrafluoroethylene conduit as an alternative to homografts. The objective of this study was to investigate the performance of bicuspid valved polytetrafluoroethylene conduits used for right ventricular outflow tract reconstruction in children aged less than 2 years and to evaluate risk factors for earlier conduit explant. METHODS: We performed an Institutional Review Board-approved retrospective chart review of all patients aged less than 2 years who underwent surgical right ventricular outflow tract reconstruction with a bicuspid valved polytetrafluoroethylene conduit or homograft conduit from July 2004 to December 2014. The end points of the study were defined as conduit explant, conduit explant or reintervention, conduit stenosis, and conduit insufficiency. RESULTS: Fifty-four patients underwent 65 right ventricular outflow tract reconstructions with a bicuspid valved polytetrafluoroethylene conduit (n = 39) or a homograft conduit (n = 26, 23 pulmonary, 3 aortic). The majority of diagnoses were truncus arteriosus (n = 28) and tetralogy of Fallot with pulmonary atresia (n = 19). Median age of patients at surgery was 134 (8-323) days and 128 (7-384) days in the PTFE and homograft groups, respectively. There was no difference in demographic data between the 2 groups. Time-to-event analysis demonstrated no difference in time to explant (P = .474) or time to explant or reintervention (P = .206) between the 2 conduit types. Younger age at surgery was the only independent risk factor for conduit explant (subdistribution hazard ratio 1.104 per 30 days younger, P < .001). There was no significant influence of conduit type on the development of moderate conduit stenosis (P = .931) or severe conduit insufficiency (P = .880). Larger conduit z score was protective for the development of moderate conduit stenosis (subdistribution hazard ratio, 0.46; P = .001). CONCLUSIONS: Bicuspid valved polytetrafluoroethylene conduits are a satisfactory choice for right ventricular outflow tract reconstruction in patients aged less than 2 years. Their availability, low cost, and lack of potential sensitization make them an appealing alternative to homograft conduits.

AB - Hydrophobic and dispersible functionalized reduced graphene oxide (FrGO) was employed to prepare chitosan gel droplets by crosslinking an inverse Pickering emulsion. The emulsion was prepared using toluene as the continuous phase and a chitosan aqueous solution as the dispersed phase. The effects of the FrGO concentration and the water/oil ratio on the chitosan droplet morphology were studied. At appropriate concentrations, the FrGO acted as a stabilizer and chitosan gel droplets were formed. Decreasing the FrGO concentration or increasing the water/oil ratio was unfavorable to the formation of chitosan droplets. Using this method, drug loaded chitosan gel droplets (microgels) were prepared and their release profiles as well as the factors that influence the drug release were investigated. PMID- 29455967 TI - Gastroprotective activity of polysaccharide from Hericium erinaceus against ethanol-induced gastric mucosal lesion and pylorus ligation-induced gastric ulcer, and its antioxidant activities. AB - The gastroprotective activity of Hericium erinaceus polysaccharide was investigated in rats. The antioxidant activities were also evaluated. Pre treatment of polysaccharide could reduce ethanol-induced gastric mucosal lesion and pylorus ligation-induced gastric ulcer. The polysaccharide exhibited scavenging activities of 1, 1-diphenyl-2-picryl-hydrozyl and hydroxyl radicals, and ferrous ion-chelating ability. In the pylorus ligation-induced model, gastric secretions (volume of gastric juice, gastric acid, pepsin and mucus) of ulcer rats administrated with polysaccharide were regulated. Levels of tumor necrosis factor-alpha and interleukins-1beta in serum, and myeloperoxidase activity of gastric tissue were reduced, while antioxidant status of gastric tissue was improved. Defensive factors (nitric oxide, prostaglandin E2, epidermal growth factor) in gastric tissue were increased. These results indicate that Hericium erinaceus polysaccharide possess gastroprotective activity, and the possible mechanisms are related to its regulations of gastric secretions, improvements of anti-inflammatory and antioxidant status, as well as increments of defensive factors releases.

AB - Blend solutions of poly(epsilon-caprolactone) (PCL) and N-(2-hydroxy)-propyl-3 trimethylammonium chitosan chloride (QCh) were successfully electrospun. The weight ratio PCL/QCh ranged in the interval 95/5-70/30 while two QCh samples were used, namely QCh1 (DQ- = 47.3%; DPv- = 2218) and QCh2 (DQ- = 71.1%; DPv- = 1427). According to the characteristics of QCh derivative and to the QCh content on the resulting PCL/QCh nonwoven, the nanofibers displayed different average diameter (175 nm-415 nm), and the nonwovens exhibited variable porosity (57.0%-81.6%), swelling capacity (175%-425%) and water vapor transmission rate (1600 g m-2 24 h 2500 g m-2 24 h). The surface hydrophilicity of nonwovens increases with increasing QCh content, favoring fibroblast (HDFn) adhesion and spreading. Tensile tests revealed that the nonwovens present a good balance between elasticity and strength under both dry and hydrated state. Results indicate that the PCL/QCh electrospun nonwovens are new nanofibers-based biomaterials potentially useful as wound dressings. PMID- 29455969 TI - Application of response surface methodology to tailor the surface chemistry of electrospun chitosan-poly(ethylene oxide) fibers. AB - Chitosan is a promising biocompatible polymer for regenerative engineering applications, but its processing remains challenging due to limited solubility and rigid crystalline structure. This work represents the development of electrospun chitosan/poly(ethylene oxide) blend nanofibrous membranes by means of a numerical analysis in order to identify and tailor the main influencing parameters with respect to accessible surface nitrogen functionalities which are of importance for the biological activity as well as for further functionalization. Depending on the solution composition, both gradient fibers and homogenous blended fiber structures could be obtained with surface nitrogen concentrations varying between 0 and 6.4%. Response surface methodology (RSM) revealed chitosan/poly(ethylene oxide) ratio and chitosan molecular weight as the main influencing factors with respect to accessible nitrogen surface atoms and respective concentrations. The model showed good adequacy hence providing a tool to tailor the surface properties of chitosan/poly(ethylene oxide) blends by addressing the amount of accessible chitosan.

AB - Cellulose nanofibrils (CNFs) were firstly prepared by 2,2,6,6 tetramethylpiperidine-1-oxyl (TEMPO) oxidation and further oxidized to 2,3 dialdehyde nanocelluloses (DANCs) by periodate oxidation. Furthermore, by using DANCs as reducing as well as stabilizing agent, palladium (Pd) and gold (Au) nanoparticles (NPs) supported on nanocellulose (PdNPs@NC and AuNPs@NC) were synthesized, respectively. The reduction of Pd or Au ions to its metallic form by DANCs was confirmed by UV-vis spectra, XRD, and XPS. TEM results showed that Pd and Au NPs were homogenously deposited onto cellulose nanofibrils, respectively. The catalytic performance of PdNPs@NC was further investigated by Suzuki coupling reaction. The product yield of the Suzuki coupling reaction between aryl bromides and phenyl boronic acid was more than 90% after 1 h with 0.1 mol% PdNPs@NC catalyst, which demonstrated that the synthesized PdNPs@NC nanohybrid could be successfully applied in Suzuki coupling reaction with an efficient catalytic activity. PMID- 29455971 TI - Chitosan-based ion-imprinted cryo-composites with excellent selectivity for copper ions. AB - An original strategy is proposed here to design chitosan-based ion-imprinted cryo composites (II-CCs) with pre-organized recognition sites and tailored porous structure by combining ion-imprinting and ice-templating techniques. The cryo composites showed a tube-like porous morphology with interconnected parallel micro-channels, the distance between the channel walls being around 15 MUm. Both the entrapment of a natural zeolite and the presence of carboxylate groups, generated by partial hydrolysis of amide moieties, led to II-CCs with controlled swelling ratios (25-40 g/g, depending on pH) and enhanced overall chelating efficiency (260 mg Cu2+/g composite). To point out the importance of introducing Cu2+ recognition sites, sorption experiments using mixtures of Cu2+ and other competing ions (Co2+, Ni2+, Zn2+ or/and Pb2+) were also carried out. The higher values of selectivity coefficients obtained for the II-CCs compared to those of non-imprinted ones highlight the remarkable potential of our sorbents for decontamination of wastewaters and recycling of Cu2+ ions.

AB - Carboxymethyl starch-g-polyvinylpyrolidones (CMS-g-PVPs) were prepared by grafting of carboxymethyl starch (CMS) with N-vinylpyrolidone (NVP) using different initiators. The grafting percentage of all the modified starches was determined and the modified starch (CMS-g-PVP-5) with maximum grafting percentage was characterized by elemental analysis, 1H NMR and FT-IR spectroscopy. Crystallinity and thermal properties of CMS-g-PVP-5 were analysed by XRD and TGA, respectively. CMS-g-PVP-5 was then utilized for the adsorption of Rhodamine 6G (dye) from water under different pH, temperature, adsorbate doze and adsorbent concentration. This modified starch showed good adsorption ability towards Rhodamine 6G. CMS-g-PVP-5 was also applied for the adsorption of ammonia gas and proved an exciting adsorbent for ammonia. PMID- 29455973 TI - Microbicidal gentamicin-alginate hydrogels. AB - Sodium alginate (Alg) reacted with antibiotic gentamicin sulfate (GS) in an aqueous-phase condition mediated by carbodiimide chemistry, in the molar ratios Alg: GS of (1:0.5), (1:1) and (1:2). The Alg-GS conjugated derivatives were characterized by elemental analysis for nitrogen content, Fourier transform infrared spectroscopy in the attenuated total reflection mode (FTIR-ATR), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), thermogravimetric analyses (TGA) and water sorption measurements. XPS and FTIR ATR analyses clearly indicated that GS molecules covalently attached to the backbone of the alginate chains by amide bond formation. The highest amount of GS bound to Alg (43.5 +/- 0.4 wt%) and the highest swelling ratio (4962 +/- 661%) were observed for the Alg-GS (1:2) sample. Bioluminescence assays with Pseudomonas aeruginosa PAO1/lecA:lux and colony forming counting of Staphylococcus aureus and Escherichia coli upon contact with all Alg-GS conjugates revealed microbicidal activity; however, Alg-GS (1:2) was the most efficient, due to the highest GS content. PMID- 29455974 TI - Structural elucidation of a pectic polysaccharide from Fructus Mori and its bioactivity on intestinal bacteria strains. AB - Many studies suggested that polysaccharides could impact on the gut microbiota. To discover new polysaccharides which influence intestinal beneficial bacteria, a pectin polysaccharide FMP-6-S2 with an average molecular weight of 86.83 kDa was purified from Fructus Mori. The monosaccharide residue analysis indicated that FMP-6-S2 was composed of rhamnose, galacturonic acid, galactose and arabinose in a molar ratio of 30.86: 24.78: 28.70: 15.61. The backbone of FMP-6-S2 contained 1, 4-linked alpha-GalpA and 1, 2-linked alpha-Rhap with branches substituted at C 4 position of rhamnose. The branches were composed of 1, 4-linked beta-Galp, terminal (T) - and 1, 3, 6-linked beta-Galp, T- and 1, 5-linked alpha-Araf. Bioactivity test results suggested that FMP-6-S2 and its degraded product could promote growth of intestinal bacteria, B. thetaiotaomicron, which is a dominate strain in the gut of human to benefit intestinal mucosa. These results suggested that FMP-6-S2 and its degraded product might improve human wellness by modulating B. thetaiotaomicron.

AB - A novel natural bioflocculant resource of Ruditapes philippinarum conglutination mud (RPM) with the effective flocculation components was firstly reported in this study. Experimental results showed that the maximum flocculation activity (FR) of RPM to kolin clay reached 86.7% in deionized water assay system and 91.8% in sea water assay system. RPM could flocculate marine microalgae Chlorella salina with a FR of 74.1%. The crude RPM polysaccharides extract(RPMP) were composed of 97.8% (w/w) polysaccharides and 2.2% (w/w) protein and the functional components of pure RPMP were firstly discovered to be two complex heteropolysaccharides of RPMP 1 and RPMP-2 with similar monosaccharides composition except glucose content. The molecular weights of RPMP-1 and RPMP-2 were 5.7 kDa and 18.0 kDa, respectively. It is interesting to find that RPMP-1 and RPMP-2 exhibited synergistic flocculation activity of 65.6% at a mass ratio of 2:1 as in crude RPMP, suggesting the original proportion is significant to synergistic flocculation.

AB - The lanthanide complexes [Yb(fac)3(H2O)2, Yb(tta)3(H2O)2, Nd(tta)3(H2O)2] functionalized nanofibrillated cellulose (Ln-NFC) nanopapers with near-infrared (NIR) luminescence and high transparency are rapidly fabricated after solvent exchange using a simple suction filtration film-making method. The effects of NFC and lanthanide complexes content on their photophysical properties of Ln-NFC nanopapers and their mechanism of UV filters are fully investigated. With increasing lanthanide complexes content in the Ln-NFC nanopaper, their transmittances are gradually decreased while their NIR luminescences are obviously increased. Yb-fac NFC nanopaper has high UVB block rate at 298 nm, whereas the high UVA block ratio of Ln-tta NFC nanopaper is observed at 345 nm. Ln-NFC nanopapers show a much higher photostability without decomposition under UV irradiation at 365 nm over 5 h. The emission spectra of the Ln-NFC nanopaper process the NIR luminescence of the corresponding lanthanide ions through the efficient triplet-triplet energy transfer process. Ln-NFC nanopapers can bring a brilliant future for UV filters, labeling fields and marking soft materials application.

AB - This work provides an in-depth analysis on how the addition of different microalgae species (Nannochloropsis, Spirulina and Scenedesmus) affected the structural and physicochemical properties of thermoplastic corn starch biocomposites. Structural characterization was conducted by combined SAXS/WAXS experiments and it was correlated with mechanical and barrier properties of the biocomposites. A water vapour permeability drop of ca. 54% was observed upon addition of the different microalgae species. The oxygen permeability and the mechanical properties of biocomposites containing Spirulina or Scenedesmus were not improved since the presence of microalgae hindered the re-arrangement and packing of the lamellar structure of starch polymeric chains, according to the SAXS results. Nannochloropsis caused a great reduction of the matrix rigidity and, the oxygen permeability was also improved. Therefore, all of these features make the Nannochloropsis biocomposites an alternative to generate biodegradable food packaging materials with the additional advantage that they can be easily scaled-up. PMID- 29455978 TI - Chitosan adsorption on nanofibrillated cellulose with different aldehyde content and interaction with phosphate buffered saline. AB - The chitosan adsorption on films prepared using nanofibrillated cellulose (NFC) with different content of aldehyde group was studied by means of Quartz Crystal Microbalance with Dissipation (QCM-D). Results showed that frequency change (Deltaf) was higher when the chitosan adsorbed on NFC film consisting more aldehyde group indicating the higher adsorption. The (Deltaf) and dissipation (DeltaD) factors completely changed during adsorption of chitosan pre-treated with acetic acid: Deltaf increased and DeltaD decreased, oppositely to un-treated chitosan adsorption. After acid treatment, molecular weight and crystallinity index of chitosan decreased addition to change in chemical structure. It was found that more phosphate buffered saline (PBS), as a model liquid for wound exudate, adsorbed to acid treated chitosan-NFC film, especially to film having more aldehyde groups. Comparing with bare NFC film, chitosan-NFC films adsorbed less PBS because chitosan crosslinked the NFC network and blocked the functional groups of NFC and thus, preventing swelling film. PMID- 29455979 TI - Proton exchange membrane based on chitosan and solvent-free carbon nanotube fluids for fuel cells applications. AB - Poor dispersion and inert ionic conduction are two major obstacles towards using carbon nanotubes (CNTs) to modify polymer electrolyte membranes (PEMs) in energy conversion devices. In this work, solvent-free carbon nanotube fluids (CNT fluids) with liquid-like behavior are prepared through an ion exchange method and incorporated into a chitosan (CS) matrix to fabricate composite membranes. The electrostatic interactions between SO3- groups in the CNT fluids and NH2 groups in the CS matrix, in addition to the unique flow properties of the CNT fluids, promote the uniform dispersion of CNT fluids in the CS matrix. Markedly, the CS/CNT fluid-3 composite membrane is simultaneously reinforced and toughened by 180% and 300% compared to pure CS membrane, respectively. Moreover, the SO3- groups in the CNT fluids facilitate the proton transfer such that the proton conductivity of CS/CNT fluid-3 composite membrane reaches a maximum value of 0.044 S cm-1 at 80 degrees C. PMID- 29455980 TI - A one-step approach to make cellulose-based hydrogels of various transparency and swelling degrees. AB - This work reports a "one-step" approach to make cellulose-based hydrogels in NaOH/urea aqueous solution via mixing N,N'-methylene bisacrylamide (MBA) with cellulose solution at room temperature. The hydrogels were revealed to be formed by an addition reaction between the double bonds of MBA and the hydroxyl groups of cellulose. Two states of hydrogels, i.e. the freshly prepared hydrogels and the hydrogels at swelling equilibrium state in deionized water, were prepared. Water retention of the hydrogels can reach up to 330 g H2O/g dry hydrogel. The freshly prepared hydrogels showed increased mechanical strength and high transparency (94%) with the addition of MBA. The hydrogels at swelling equilibrium state displayed macroporous structures with the pore diameter up to 0.65 mm and showed significantly varied properties with various amount of MBA. The obtained hydrogel could be used as a good blank template for the functionalization of cellulose-based hydrogel. PMID- 29455981 TI - Digestibility of fucosylated glycosaminoglycan from sea cucumber and its effects on digestive enzymes under simulated salivary and gastrointestinal conditions. AB - The digestibility of fucosylated glycosaminoglycan (FG) and its effects on digestive enzymes were investigated using an in vitro digestion model. Results showed that the molecular weight and the reducing sugar content of FG were not significantly changed, and no free monosaccharides released from FG were detected after the salivary, gastric and intestinal digestion, indicating that both the backbone and the sulfated fucose branches of FG are resistant to be cleaved in the saliva and gastrointestinal tract environments. Furthermore, FG can dose dependently inhibit digestive enzymes such as alpha-amylase, pepsin and pancreatic lipase in different degrees under the simulated digestion conditions due to the sulfate and carboxyl groups. These physiological effects of FG may help control the postprandial glucose concentration and have the potential in the prevention or treatment of reflux disease and obesity. The findings may provide information on the digestibility and beneficial physiological effects of FG as a potential natural product to promote human health. PMID- 29455982 TI - Investigation of OH bond energy for chemically treated alfa fibers. AB - This work aims to study the hydrogen bond energy and distance for different samples of alfa fibers treated with thymol. The treatment duration and thymol concentration were varied and seem to have a great influence on infrared band intensities and positions. The number of hydrogen bonds is related to the infrared band intensity, whereas their energy and distance depend on the infrared band position. It was proven that the free hydroxyl groups are weakened and tend to disappear with fiber treatment. It is the same for intermolecular hydrogen bands between cellulosic chains that present a decrease in both intensity and frequency. The two intramolecular hydrogen bands increase in intensity but exhibit different behaviors regarding the calculated energy: while the band at 3268 cm-1 is weakened and shifted to higher wavenumbers, that at 3338 cm-1 keeps the same peak position and energy. PMID- 29455983 TI - Electrochemical writing on edible polysaccharide films for intelligent food packaging. AB - Polysaccharide films used as intelligent food packaging possess the advantages of renewability, safety and biodegradability. Printing on the polysaccharidic food packaging is challenging due to the high demand for edible-ink and the need for a suitable printing technique. In this work, we propose an electrochemical method for writing on polysaccharide film. Unlike conventional printing, this electrochemical writing process relies on the pH responsive color change of anthocyanin embedded in the chitosan/agarose hydrogel. By biasing a negative potential to a stainless wire (used as a pen) contacting the surface of the chitosan/agarose/ATH hydrogel, the locally generated pH change induced the color change of ATH and wrote programmed information on the hydrogel. We demonstrate the writing can be temporary in the hydrogel but stable when the hydrogel is dried. We further demonstrate that the written film is applicable for the detection of the spoilage of crucian fish. The reported electrochemical writing process provides a novel method for printing information on polysaccharide film and great potential for intelligent food packaging.

AB - For the first time, a ternary hybrid system composed of halloysite nanotubes, HNTs, cyclodextrin nanosponges, CDNS, and g-C3N4 is prepared and used for immobilization of Pd(0) nanoparticles and development of a heterogeneous catalyst, Pd@HNTs-CDNS-g-C3N4 for promoting ligand and copper-free Sonogashira and Heck coupling reactions in aqueous media. HNT as a porous tubular clay with outstanding thermal, mechanical and textural properties can act as a support for immobilizing Pd nanoparticles. The role of CDNS can be explained on the base of its capability to form inclusion complexe with substrates and bringing them in the vicinity of the catalytic active sites. Regarding the role of g-C3N4 in catalysis, it is proved that its presence can suppress the Pd leaching dramatically. The contribution of each component as well as synergistic effect between them results in high catalytic activity and recyclability (up to 10 reaction runs) of the catalyst. PMID- 29455984 TI - Hyaluronate coating enhances the delivery and biocompatibility of gold nanoparticles. AB - For targeted delivery with nanoparticles (NPs) as drug carriers, it is imperative that the NPs are internalized into the targeted cell. Surface properties of NPs influence their interactions with cells. We examined the responses of retinal pigment epithelial cells, NIH 3T3 fibroblast cells, and Chinese hamster ovary cells to gold nanoparticles (Au NPs) in their nascent form as well as coated with end-thiolated hyaluronate (HS-HA). The grafting density of HS-HA on Au NPs was calculated based on total organic carbon measurements and thermal gravimetric analysis. We imaged the intracellular NPs by 3D confocal microscopy. We quantified viability and generation of reactive oxygen species (ROS) of the cells to Au NPs and monitored cell-surface attachment via electrical cell-substrate impedance sensing. The results confirmed that receptors on cell surfaces, for HA, are critical in internalizing HS-HA-Au NPs, and HA may mitigate ROS pathways known to lead to cell death. The 50- and 100-nm HS-HA-Au NPs were able to enter the cells; however, their nascent forms could not. This study shows that the delivery of larger Au NPs is enhanced with HS-HA coating and illustrates the potential of HA-coated NPs as a drug delivery agent for inflamed, proliferating, and cancer cells that express CD44 receptors. PMID- 29455986 TI - Simultaneous improvement of thermal stability and redispersibility of cellulose nanocrystals by using ionic liquids. AB - Cellulose nanocrystals (CNCs) are predominantly obtained by the traditional sulfuric acid hydrolysis process. However, as-prepared CNCs powder features low thermal stability and poor redispersibility due to the existence of sulfonate groups and the hydrogen bond interaction among particles. Herein, by mixing the ionic liquid [BMIm][BF4] with freshly prepared CNCs without dialysis through a simple rotary evaporate procedure, the simultaneous improvement of thermal stability and redispersibility of CNCs has been achieved. By combining FTIR, TGA and DLS measurements, the critical role of rotary evaporates process for improving the thermal stability of CNCs has been discussed. Furthermore, the poly(lactic acid) (PLLA)/IL-CNC nanocomposites with enhanced mechanical properties were prepared by the melt-mixing method. This study provides a green and simple strategy for preparing dried CNC powders, which has a great potential in large-scale production of fully bio-based nanocomposites.

AB - The aim of this study was to develop chitosan (CS) microparticulated mucoadhesive drug delivery system (DDS) with improved therapeutic performance and biological responce. Ionotropic gelation/spray drying process was used for preparation of doxycycline hyclate (DOXY) loaded low and medium molecular weight (LMw and MMw) CS/sodium tripolyphosphate microparticles (CS/TPP MPs), further coated with ethyl cellulose (EC) using coacervation/solvent displacement technique. The relevant physico-chemical and biopharmaceutical properties were optimized using experimental design approach. Both coated and uncoated CS/TPP MPs showed high mucoadhesive potential and did not affect the viability of the tested epithelial cell line. The MPs induced slow and gradual apoptotic response in murine macrophage cell line RAW 264.7 and the observed effect depended upon formulation type and MP concentration. Biological effect of the CS-based MPs observed in our experiments point to synergism of the biological response of the carrier with the anti-inflammatory effect of DOXY. PMID- 29455988 TI - Fabrication of novel nanohybrids by impregnation of CuO nanoparticles into bacterial cellulose and chitosan nanofibers: Characterization, antimicrobial and release properties. AB - The efficiency of bacterial cellulose nanofibers (BCNF) and chitosan nanofibers (CHNF) were compared, aiming at fabricating novel organic-inorganic nanohybrids containing copper oxide (CuO) nanoparticles (NPs). FT-IR spectra confirmed the formation of real nanohybrids through occurring new interactions between CuO NPs and nanofibers. XRD results indicated that both the crystallite size and the crystallinity index of nanofibers decreased after nanohybrid formation. Noticeably, these morphological changes for CHNF were more than those for BCNF. Strong attachment of CuO-NPs to the BCNF and CHNF nanofibrils was observed in FE SEM images. After 72 h, CuO releasing for CuO-BCNF and CuO-CHNF nanohybrids was recorded as 65.5% and 47.7%, respectively. The antibacterial activity of CuO NPs against both Gram-positive and Gram-negative bacteria decreased after attachment to BCNF. However, a synergistic effect was observed between CuO and CHNF on the antimicrobial activity of CuO-CHNF nanohybrid. This study demonstrated the potential of fabricated nanohybrids in water purification and food packaging applications. PMID- 29455989 TI - Biocompatible nanocomposite of carboxymethyl cellulose and functionalized carbon norfloxacin intercalated layered double hydroxides. AB - In recent years, the development of systems with progressive drug release properties, which is an effective technique for the use of drugs, has aroused great interest in the field of controlled release formulations. In this work, hybrid materials containing citric acid cross-linked carboxymethyl cellulose (CMC) and norfloxacin (NOR) intercalated layered double hydroxide (LDH) deposited over the surface of functionalized carbon (AC) were prepared. The synthesized CMC@AC-LDHNOR nanohybrids were characterized using different techniques and in vitro NOR release behaviors were investigated in phosphate buffer saline, pH 7.4 at 37 degrees C. On the basis of the release profiles, it was found that NOR release was delayed when it was intercalated in AC-LDH which in presence of modified CMC decreases further. The nanohybrids indicated enhancement of antibacterial activity against gram-negative and gram-positive bacteria. The MTT assay showed their non-toxic behavior against ovarian normal epithelial and cancer cells, suggesting their potential use as drug carriers. PMID- 29455990 TI - Enhancement of bio-stability and mechanical properties of hyaluronic acid hydrogels by tannic acid treatment. AB - Hyaluronic acid (HA) has been widely investigated because of its excellent biocompatibility and its ability to form hydrogels with various chemical modifications. However, HA hydrogels undergo rapid degradation and exhibit poor mechanical stability under physiological conditions. Tannic acid (TA), a naturally occurring polyphenol found in plants and fruits, has recently attracted interest as a crosslinking agent because of its abundant hydroxyl groups. In this study, we prepared HA hydrogels chemically crosslinked by polyethylene glycol diglycidyl ether (PEGDE) and treated with TA in an attempt to enhance the physical properties of HA hydrogels. TA acts as a physical crosslinker owing to the strong hydrogen bonding between TA and PEGDE, resulting in improved mechanical properties that support both cell attachment and proliferation without any sign of cytotoxicity. The enzymatic stability of the HA-TA hydrogels was significantly enhanced with the addition of TA, which was attributed to the hyaluronidase inhibition activity of TA. Additionally, the antioxidant potential of TA resulted in good resistance to degradation by reactive oxygen species, which can be generated in human tissues. PMID- 29455991 TI - Water-soluble chitosan derivatives and pH-responsive hydrogels by selective C-6 oxidation mediated by TEMPO-laccase redox system. AB - Chitosan is a polysaccharide with recognized antioxidant, antimicrobial and wound healing activities. However, this polymer is soluble only in dilute acidic solutions, which restricts much of its applications. A usual strategy for improving the functionality of polysaccharides is the selective oxidation mediated by 2,2,6,6-tetra-methyl-1-piperidinidyloxy (TEMPO) using laccase as a co oxidant. In this work, the TEMPO-laccase redox system was used for the first time to selectively oxidize chitosan in order to produce tailored derivatives. The reaction was performed at pH 4.5 under continuous air supply and the oxidized products were characterized structurally and functionally. The TEMPO-laccase oxidation successfully added aldehyde and carboxylate groups to chitosan structure resulting in derivatives with oxidation between 4 and 7%. These derivatives showed increased solubility and decreased viscosity in solution. If chitosan is dissolved in diluted hydrochloric acid prior to TEMPO-laccase oxidation, a crosslinked chitosan derivative was produced, which was able to form a pH-responsive hydrogel.

AB - The current approach focuses on studying the leverage of nanosilver (AgNPs) incorporation on the dyeing process of viscose fibers by blue reactive dye. Nanosilver was straightway incorporated into viscose fibers using sodium citrate as nanogenerator. Owing to AgNPs incorporation, color of fibers was turned to greenish-blue and darker greenish color was observed with low Ag content (<1 g/kg). Regardless to the processes sequencing, color strength of fibers was magnified by increasing in Ag content. The constancy of fibers color was not affected by AgNPs inclusion, whatever the processes sequencing and Ag content. Release property of Ag from fibers into water was considerably depended on the processes sequencing. By incorporation of AgNPs firstly, the lowest Ag release value was estimated (0.25 g/kg after 24 h). Antimicrobial activities were significantly improved by AgNPs incorporation. Reduction in bacteria and fungi was reached 92.4% and 67.9% after 24 h contact time, respectively.

AB - The purpose of this study was to investigate the effects of Ostrea rivularis polysaccharide (ORP) against testicular oxidative stress injury via kelch-like ECH-associated protein 1-nuclear erythroid 2-related factor 2/antioxidant response element (Keap1-Nrf2/ARE) pathway. In pharmacological experiments in vivo, ORP administration could dose-dependently inhibit body and testicular weight loss, ameliorate epididymal sperm quality and protect reproductive impairment in cyclophosphamide-induced male Balb/c mice. Moreover, the mechanism in vivo might be elucidated that ORP could increase expression level of Nrf2 and its downstream ARE gene battery in the testis, promote production of corresponding antioxidative enzymes and protein, and enhance Keap1-Nrf2/ARE signaling pathway to avoid male reproductive dysfunction. In addition, ORP treatment could improve survival capacity of H2O2-induced TM4 cells and its antioxidant mechanism in vitro also had been verified to activate Keap1-Nrf2/ARE signaling pathway. Overall, these results showed that ORP as a potent antioxidant could reduce reproductive oxidative stress damage related to Keap1-Nrf2/ARE pathway.

AB - The physical, chemical, tensile, crystalline, thermal, and surface morphological properties of raw and alkali treated Coccinia Grandis.L Fibers (CGFs) were characterized for the first time in this work. The results of the chemical analysis indicate that, after alkali treatment, the cellulose content of CGFs increased whereas hemicelluloses, lignin and wax contents decreased. This directly influenced the tensile strength, crystallinity index, thermal stability and the roughness of alkali-treated CGFs. The thermal stability and activation energy of the CGFs improved from 213.4 degrees C to 220.6 degrees C and 67.02 kJ/mol to 73.43 kJ/mol, respectively, due to alkali treatment. The statistical approach, Weibull distribution was adopted to analyze the tensile properties. The improved properties of the alkali treated CGF indicate that it could be an appropriate material for reinforcement in polymer composites.

AB - Starch nanoparticles were produced by dialysis method from octenyl succinic anhydre (OSA) and 1,4-butane sultone (BS). The properties of the self-assembled nanoparticles were characterized by NMR spectroscopy (DOSY), fluorescence spectroscopy and dynamic light scattering (DLS). In order to investigate the formation of hydrophobic microdomains, the Nile Red dye was used as a fluorescent probe to evaluate the critical aggregation concentration (CAC) of modified starch in aqueous solution. The results show that the entrapment of the molecular guest was effective and only restricted by the solubility limit of the starch. Then, the modified starch was applied to solubilize benzo[a]pyrene (BaP) in view of degradation by Fenton process. Finally, it has been shown that 95% of BaP was degraded when it was encapsulated in OSA-BS-starch nanoparticles.

AB - Electrically conductive cotton fabric was fabricated by in situ one pot oxidative polymerization of aniline. Using a simple heterogeneous polymerization method, polyaniline (PANI) nano fibers with an average fiber diameter of 40-75 nm were grafted in situ onto cotton fabric. The electrical conductivity of the PANI nanofiber grafted fabric was improved 10 fold compared to fabric grafted with PANI nanoclusters having an average cluster size of 145-315 nm. The surface morphology of the cotton fibers was characterized using SEM and AFM. Electrical conductivity of PANI nanofibers on the cotton textile was further improved from 76 kOmega/cm to 1 kOmega/cm by increasing the HCl concentration from 1 M to 3 M in the polymerization medium. PANI grafted cotton fabrics were analyzed using FTIR, and the data showed the presence of polyaniline functional groups on the treated fabric. Further evidence was present for the chemical interaction of PANI with cellulose. Dopant level and morphology dependent electron transition behavior of PANI nanostructures grafted on cotton fabric was further characterized using UV-vis spectroscopy. The electrical conductivity of the PANI nano fiber grafted cotton fabric can be tuned by immersing the fabric in pH 2 and pH 6 solutions for multiple cycles. PMID- 29455998 TI - Cationic xylan- (2-methacryloyloxyethyl trimethyl ammonium chloride) polymer as a flocculant for pulping wastewater. AB - In this work, pulp mill wastewater was treated with a novel polymer flocculant, which was synthesized through polymerizing (2-methacryloyloxyethyl) trimethyl ammonium chloride (DMC) and xylan. Xylan-DMC polymer removed 94.5% of turbidity, 61.7% of chemical oxygen demand (COD), 45.0% of lignin, 65.7% of sugar and 73.5% of biological oxygen demand (BOD) from the wastewater at the polymer concentration of 500 mg/L. The flocculation mechanism was fundamentally assessed with determining hydrodynamic size and chord length of flocs in the wastewater at different dosages of xylan-DMC polymer in the system. By adding polymers, the number of flocs with a small chord length (10-50 MUm) decreased, while that with a large chord length (150-300 MUm) increased, indicating the small particles agglomerated via bridging induced by the polymer. The sedimentation of formed flocs was quantitatively investigated by a vertical scan analyzer and the results depicted that the flocs could settle readily from the system. PMID- 29455997 TI - Effect of dynamic high pressure on emulsifying and encapsulant properties of cashew tree gum. AB - Dynamic high pressure (DHP) has been applied in the physical modification of biopolymers as polysaccharides, proteins and gums. It is known that DHP is able to promote degradation of polysaccharides (e.g. molecular weight reduction). However, few studies have assessed the effect of DHP on the emulsifying and encapsulating properties of polysaccharides. Thus, this study aimed to investigate the effect of DHP on the emulsifying (average droplet size and particle size distribution, optical and confocal scanning laser microscopy, rheology, zeta potential and electric conductivity, creaming index, and turbidity) and encapsulating (scanning electronic microscopy, flavor retention, average droplet size, and particle size distribution) properties of cashew tree gum (CG). The application of DHP process improved the emulsifying capacity of cashew tree gum (CG) by reducing the medium droplet size (D3,2 and D4,3), increasing the turbidity and improving the emulsion stability. However, no effect of DHP was observed on the encapsulating capacity of CG. PMID- 29455999 TI - Cellulaose acetate based thin film nanocomposite reverse osmosis membrane incorporated with TiO2 nanoparticles for improved performance. AB - In this work, cellulose acetate (CA) based thin film nanocomposite reverse osmosis (RO) membranes were fabricated using dissolution casting method by optimizing the CA/polyethylene glycol (CA/PEG-400) ratios for improved RO performance. The selectivity of optimized membrane was further enhanced by incorporating TiO2 (0-25 wt.%) nanoparticles. Fourier transform infrared spectroscopy (FTIR), thermogravimetric analyzer (TGA), scanning electron microscopy (SEM) and X-ray diffraction (XRD) were conducted to characterize control and modified membranes for the analysis of functional groups, thermal properties, morphology and structural investigation respectively. CP-2 of CA/PEG 400 (80/20) was selected for further modification with TiO2 nanoparticles. The maximum salt rejection (95.4%) was observed for the membrane having 15% TiO2 nanoparticles. Further escalation of TiO2 concentration resulted in the agglomeration of nanoparticles which subsequently decreased the permeation flux. The test results demonstrated that the modified membranes had higher salt rejection and chlorine resistance, lower degradation profile, successful inhibition of Escherichia coli growth and facilitating permeation flux compared to the control membrane.

AB - Development of bio-based hydrogels with good mechanical properties and high electrical conductivity is of great importance for their excellent biocompatibility and biodegradability. Novel electrically conducive and tough poly(vinyl alcohol)/sodium alginate (PVA/SA) composite hydrogel was obtained by a simple method in this paper. PVA and SA were firstly dissolved in distilled water to form the composite solution and the pure PVA/SA hydrogel was obtained through the freezing/thawing process. The pure PVA/SA hydrogels were subsequently immersed into the saturated NaCl aqueous solution to increase the gel strength and conductivity. The effect of the immersing time on the thermal and mechanical properties of PVA/SA hydrogel was studied. The swelling properties and the antiseptic properties of the obtained PVA/SA hydrogel were also studied. This paper provided a novel way for the preparation of tough hydrogel electrolyte. PMID- 29456001 TI - Soluble soybean polysaccharide/TiO2 bionanocomposite film for food application. AB - In the current study, a set of biodegradable soybean polysaccharide (SSPS) nanocomposites containing different ratios of TiO2 nanoparticles was characterized as new packaging system. X-ray diffraction (XRD) measurement showed that the crystalline structure of the TiO2 nanoparticles remained intact in the polysaccharide matrix and the surface of nanocomposites containing 1-3% TiO2 was observed morphologically uniform under scanning electron microscopy (SEM). Dynamic mechanical thermal analysis revealed that the magnitude of storage modulus was 3.62-fold higher in SPSS/TiO2 nanocomposites containing 7 wt.% of TiO2 than control SSPS indicating improvement in the physical properties of the film supposed to be utilized for food packaging. With respect to the concern over the safety of these nanocomposites, inductively coupled plasma-optical emission spectroscopy (ICP-OES) showed that no TiO2 was detected in bread samples covered by SSPS/TiO2 film and stored for 6 months. Similarly, the nanocomposite films only released a minuscule amount (21.05 +/- 0.054 ppm) of TiO2 in water. TiO2 nanoparticles were found in the plasma membrane of epithelial cell line after long-term exposure (10-day) of these cells to large amounts of the free nanoparticles. SSPS/TiO2 nanocomposites showed excellent antimicrobial activity against Staphylococcus aureus PTCC 1431 (ATCC 25923), while neither anti cancerous nor pro-cancerous activity was observed for these nanocomposites denoting their neutrality with respect to cancer suppression or progression in gastrointestinal tract. In conclusion, SSPS/TiO2 nanocomposites could be a promising packaging system for food industries' objective regarding their physical characteristics, low rate of Ti transition, and low health risk. PMID- 29456002 TI - Extraction and characterization of polysaccharides from tamarind seeds, rice mill residue, okra waste and sugarcane bagasse for its Bio-thermoplastic properties. AB - The aim of the present study is to extract potential thermoplastic polysaccharides from agricultural industrial wastes. Polysaccharides were extracted from renewable agro industrial wastes such as tamarind seeds [rich in starch (TSS)], okra head waste [rich in mucilage polysaccharide (OMP)], sugarcane bagasse [rich in cellulose (SBC)] and residual rice mill wastes [rich in starch and fiber (RS)]. Urigam variety of tamarind seed starch found to be an amylose rich starch. Different polysaccharides extracted from agro wastes were found to be having high thermal stability, except okra polysaccharide (comparatively low). X-ray diffraction pattern of tamarind seed starch proved its high crystallinity index. Crystallinity index of investigated polysaccharides were found to be in the order of SBC > TSS > RS > OMP. Chemical nature of extracted polysaccharides was confirmed by Fourier transform infrared spectroscopic analysis. Residual rice bran starch granules and tamarind seed starch globules were found to be having comparatively reduced particle size than sugarcane bagasse cellulose and okra mucilage. Scanning electron microscopic analysis revealed the cluster formations of RS granules and TSS globules. Residual rice bran starch found to be associated with other fibers (present in outer coat of rice). Okra mucilage and SBC were examined to be having linear sheets and linear bundles structures, respectively.

AB - Swallow root pectic oligosaccharide fraction (SRO1) from swallow root pectic polysaccharide (SRPP) possessed a molecular size of 831 Da. Structural analysis revealed that it is a rhamnogalacturonan I type, bearing arabinogalactan side chain with beta-d-(1->4) galactose along with alpha-l-Araf (1->5)-alpha-l-Araf (1 >3) structure on alpha-d-GalA-OAc-(1->2)-alpha-l-Rha-(1->4)- linear backbone. beta-d (1->4) linked galactose being the specific sugar for galectin-3, SRO1 had potentials in inhibiting galectin-3 mediated cancer progression. SRO1 inhibited galectin-3 mediated agglutination, in vitro, effectively with MIC of 1.08 MUg/ mL and down regulated mRNA levels of galectin-3 (~92%) along with its downstream key protein that inhibits apoptosis - survivin (~78%) suggesting the capability of SRO1 in inhibiting galectin-3 mediated cancer promoting pathway. This is the first report, which highlights the inhibition of interplay of galectin-3 and survivin by a dietary pectic oligosaccharide. PMID- 29456004 TI - The effect of oxyalkylation and application of polymer dispersions on the thermoformability and extensibility of paper. AB - Wood fiber-based packaging materials, as renewable materials, have growing market potential due to their sustainability. A new breakthrough in cellulose-based packaging requires some improvement in the mechanical properties of paper. Bleached softwood kraft pulp was mechanically treated, in two stages, using high- and low-consistency refining, sequentially. Chemical treatment of pulp using the oxyalkylation method was applied to modify a portion of fiber material, especially the fiber surface, and its compatibility with polymer dispersions including one carbohydrate polymer. The results showed that the compatibility of the cellulosic fibers with some polymers could be improved with oxyalkylation. By adjusting mechanical and chemical treatments, and the thermoforming conditions, the formability of paper was improved, but simultaneously the strength and stiffness decreased. The results suggest that the formability of the paper is not a direct function of the extensibility of the applied polymer, but also depends on the fiber network structure and surface energy. PMID- 29456005 TI - Bioconversion of chitosan into chito-oligosaccharides (CHOS) using family 46 chitosanase from Bacillus subtilis (BsCsn46A). AB - BsCsn46A, a GH family 46 chitosanase from Bacillus subtilis had been previously shown to have potential for bioconversion of chitosan to chito-oligosaccharides (CHOS). However, so far, in-depth analysis of both the mode of action of this enzyme and the composition of its products were lacking. In this study, we have employed size exclusion chromatography, 1H NMR, and mass spectrometry to reveal that BsCsn46A can rapidly cleave chitosans with a wide-variety of acetylation degrees, using a non-processive endo-mode of action. The composition of the product mixtures can be tailored by varying the degree of acetylation of the chitosan and the reaction time. Detailed analysis of product profiles revealed differences compared to other chitosanases. Importantly, BsCsn46A seems to be one of the fastest chitosanases described so far. The detailed analysis of preferred endo-binding modes using H218O showed that a hexameric substrate has three productive binding modes occurring with similar frequencies. PMID- 29456006 TI - Effective cellulose nanocrystal imaging using transmission electron microscopy. AB - Characterization of cellulose nanocrystals (CNCs) is often complex and tedious. With their increased use for biological materials, polymer reinforcing agents, and other applications, better characterization methods of CNCs are needed to ensure product quality. However, because of their small size, hydrogen bonding, and low electron density, individual CNCs are difficult to image with high resolution and magnification using electron microscopy. Methods to help counter these challenges include staining for increased contrast and techniques to increase dispersion. This work tested several stains, dispersing agents, and sample supports to find a consistent method of individualizing CNCs and providing good contrast for imaging in transmission electron microscopy (TEM). The most consistent method found uses a low concentration of CNCs, bovine serum albumin as a dispersing agent, and Nanovan(r) as the contrasting stain on a silicon monoxide coated Formvar TEM grid. PMID- 29456007 TI - Fucosylated chondroitin sulfate is covalently associated with collagen fibrils in sea cucumber Apostichopus japonicus body wall. AB - Fucosylated chondroitin sulfate (fCS) is the major carbohydrate constituent of sea cucumber. However, the distribution of fCS in the sea cucumber body wall has not been fully described. We addressed this in the present study employing Apostichopus japonicus as the material, a sea cucumber species with significant commercial importance. It was found that fCS was covalently attached to collagen fibrils via O-glycosidic linkages. Transmission electron microscopy analysis revealed that fCS precipitate was present in gap regions of collagen fibrils as roughly globular or ellipsoidal dots. The fCS dots arranged circumferentially around the fibrils with an axial repeat period that matched the periodicity of the fibrils. Physicochemical analysis indicated that the presence of fCS significantly increased the negative charge of the fibrils. These findings provide novel insight into fCS distribution in the sea cucumber body wall and its supramolecular organization with other macromolecules.

AB - Protein crosslinked nanogels which combine the merits of nanogels and the specific biological activity from protein have emerged as fascinating protein delivery systems. However, the fragility and low density of reactive group in proteins, especially low electric density of neutral proteins seriously limited the fabrication of protein crosslinked nanogels without affecting their bioactivities. Here, we demonstrated a facile ion-assisted method to fabricate neutral protein crosslinked nanogels. Oxidized sodium alginate (OSA) with aldehyde groups and low viscosity was successfully synthesized, which could reversibly form nanogels via addition and removal of divalent cation. Subsequently, hemoglobin and myoglobin were used as representative neutral proteins to fabricate stable protein crosslinked OSA nanogels under the assist of divalent cation followed by in situ Schiff base formation between OSA and proteins. The mild fabrication condition guaranteed the structural integrity and bioactivity of proteins in the obtained protein crosslinked nanogels. This ion assisted method was expected to bring a new opportunity for fabricating versatile functional biohybrid nanogels systems. PMID- 29456009 TI - Novel in situ forming hydrogel based on xanthan and chitosan re-gelifying in liquids for local drug delivery. AB - Injectable hydrogels have been an attractive topic in biomaterials. However, during gelation in vivo, they are easy to disperse due to tissue exudates, thus leading to failure of controlled drug release. To solve this problem, we present a novel polysaccharide-based injectable hydrogel via self-crosslinking of aldehyde-modified xanthan (Xan-CHO) and carboxymethyl-modified chitosan (NOCC). The physical properties were optimized by adjusting the mass ratio of Xan-CHO and NOCC. Experiments revealed that this material exhibited the characteristics of self-healing, anti-enzymatic hydrolysis, biocompatibility and biodegradability. The releasing curve demonstrated stable release of BSA-FITC within 10 h after injection in liquids. After incorporation with a vascular endothelial growth factor, there was an interaction between this biomaterial and the host, which accelerated the reconstruction of the abdominal wall in rats. Therefore, this injectable hydrogel, as a drug delivery system, can prevent drug outburst in a variety of settings and function as a tissue scaffold. PMID- 29456010 TI - Extraction and characterization of arrowroot (Maranta arundinaceae L.) starch and its application in edible films. AB - This research work aimed extraction and characterization of arrowroot starch. Besides, the effects of different concentrations of starch (2.59-5.41%, mass/mass) and concentrations of glycerol (9.95-24.08%, mass versus starch mass) on films properties were evaluated by a rotational central composite 22 experimental design. Arrowroot starch showed high amylose content (35%). Low values were found for the swelling power and solubility index. The X-ray diffraction showed "C" type crystalline structures, while thermogram showed Tg around of 118 and 120 degrees C. The thermogravimetric analysis showed that 40% of mass loss of starch occurred between 330 and 410 degrees C. The films were homogeneous, transparent and manageable. Starch and glycerol concentrations played a significant role in thickness and solubility in water of films, but was not significant for water vapor permeability and tensile strength. Therefore, arrowroot is a very promising starch source for application in films. PMID- 29456011 TI - Effect of retention rate of fluorescent cellulose nanofibrils on paper properties and structure. AB - In this work, we report a new characterization method using fluorescent cellulose nanofibrils to analyze retention and loss rates in the papermaking process. Cellulose nanofibrils (CNF) were isolated from chemical pulp by enzymatic pretreatment and used as a strengthening additive in sheet forming. The aim of this paper was to investigate its effects on flocculation, retention and loss rate and the physical and mechanical properties. CNF was subjected to fluorescent labeling with RBITC (Rhodamine B isothiocyanate), and the retention of fluorescent cellulose nanofibrils (FCNF) was analyzed by elemental analysis and fluorescence intensity. The retention and loss rate of the FCNF decreased with increasing the addition of FCNF. Laser Confocal Scanning Microscopy (LCSM) and Scanning Electron Microscope (SEM) images confirmed that FCNF can be evenly distributed in the paper. A thorough investigation of the relation between the retention rate and papersheet performance was conducted. PMID- 29456012 TI - Injectable and body temperature sensitive hydrogels based on chitosan and hyaluronic acid for pH sensitive drug release. AB - Hydrogels based on chitosan/hyaluronic acid/beta-sodium glycerophosphate demonstrate injectability, body temperature sensitivity, pH sensitive drug release and adhesion to cancer cell. The drug (doxorubicin) loaded hydrogel precursor solutions are injectable and turn to hydrogels when the temperature is increased to body temperature. The acidic condition (pH 4.00) can trigger the release of drug and the cancer cell (Hela) can adhere to the surface of the hydrogels, which will be beneficial for tumor site-specific administration of drug. The mechanical strength, the gelation temperature, and the drug release behavior can be tuned by varying hyaluronic acid content. The mechanisms were characterized using dynamic mechanical analysis, Fourier transform infrared spectroscopy, scanning electron microscopy and fluorescence microscopy. The carboxyl group in hyaluronic acid can form the hydrogen bondings with the protonated amine in chitosan, which promotes the increase of mechanical strength of the hydrogels and depresses the initial burst release of drug from the hydrogel. PMID- 29456013 TI - Oxidation pattern of curdlan with TEMPO-mediated system. AB - In this study, the TEMPO-mediated (TEMPO/NaBr/NaClO) oxidation pattern of curdlan was investigated through comprehensively structural analysis of the corresponding oxidized products. During the structural analysis, infrared spectroscopy (IR), nuclear magnetic resonance (NMR) spectroscopy, gel permeation chromatography tandem multiple angle laser scattering (GPC-MALS) and ultra-high performance liquid chromatography tandem quadrupole time of flight mass spectrometry (UHPLC Q/TOF-MS) were applied. As a result, the homogenous beta1-3 polyglucuronic acids (MW, 49.8, 29.8 and 7.0 kDa) were obtained with proper amount of oxidant (5.36 mmol NaClO) at various temperatures (4, 25, 50 degrees C), respectively. Compared to the oxidation of 1-4 linked glucan (starch and cellulose) with TEMPO mediated system at same reaction conditions, higher degree of specific oxidation and less degradation were observed in that of 1-3 linked curdlan. The glycosylation at position 3 could stabilize the sugar ring, which inactivates the non-specific oxidation related hydroxyl groups on the sugar ring. Thus, the TEMPO mediated system has higher selectivity to oxidize the primary hydroxyl groups of 1-3 linked curdlan and form polyglucuronic acid than those observed in the oxidation of starch and cellulose. In addition, same as those observed in previous work about starch, higher the temperature was used in the oxidation with TEMPO system, higher the activity of oxidant (NaClO solution) was, more non specific oxidation occurred, and more the degradation were observed. PMID- 29456014 TI - Structural characterization of polysaccharides from Cabernet Franc, Cabernet Sauvignon and Sauvignon Blanc wines: Anti-inflammatory activity in LPS stimulated RAW 264.7 cells. AB - The structural characterization of the polysaccharides and in vitro anti inflammatory properties of Cabernet Franc (WCF), Cabernet Sauvignon (WCS) and Sauvignon Blanc (WSB) wines were studied for the first time in this work. The polysaccharides of wines gave rise to three fractions of polysaccharides, namely (WCF) 0.16%, (WCS) 0.05% and (WSB) 0.02%; the highest one was chosen for isolation of polysaccharides (WCF). It was identified the presence of mannan, formed by a sequence of alpha-d-Manp (1 -> 6)-linked and side chains O-2 substituted for alpha-d-mannan (1 -> 2)-linked; type II arabinogalactan, formed by (1 -> 3)-linked beta-d-Galp main chain, substituted at O-6 by (1 -> 6)-linked beta-d-Galp side chains, and nonreducing end-units of arabinose 3-O-substituted; type I rhamnogalacturonan formed by repeating (1 -> 4)-alpha-d-GalpA-(1 -> 2) alpha-L-Rhap groups; and traces of type II rhamnogalacturonan. The polysaccharide mixture and isolated fractions inhibited the production of inflammatory cytokines (TNF-alpha and IL-1beta) and mediator (NO) in RAW 264.7 cells stimulated with LPS. PMID- 29456015 TI - Multi-antigenic human cytomegalovirus mRNA vaccines that elicit potent humoral and cell-mediated immunity. AB - A cytomegalovirus (CMV) vaccine that is effective at preventing congenital infection and reducing CMV disease in transplant patients remains a high priority as no approved vaccines exist. While the precise correlates of protection are unknown, neutralizing antibodies and antigen-specific T cells have been implicated in controlling infection. We demonstrate that the immunization of mice and nonhuman primates (NHPs) with lipid nanoparticles (LNP) encapsulating modified mRNA encoding CMV glycoproteins gB and pentameric complex (PC) elicit potent and durable neutralizing antibody titers. Since the protective correlates in pregnant women and transplant recipients may differ, we developed an additional mRNA vaccine expressing the immunodominant CMV T cell antigen pp65. Administration of pp65 vaccine with PC and gB elicited robust multi-antigenic T cell responses in mice. Our data demonstrate that mRNA/LNP is a versatile platform that enables the development of vaccination strategies that could prevent CMV infection and consequent disease in different target populations.

AB - The post-fusion form of Respiratory Syncytial Virus (RSV) fusion (F) protein has been used recently in clinical trials as a potential vaccine antigen with the objective of eliciting protective immune response against RSV. In this paper, in vitro antigenicity and in vivo immunogenicity of recombinant, soluble F protein of RSV (RSVsF) were evaluated by several assays. In Vitro Relative Potency (IVRP) of RSVsF was measured in a sandwich ELISA using two antibodies, each specific for epitope site A or C. Therefore, IVRP reflected the integrity of the antigen in terms of changes in antibody binding affinity of either or both of these sites. RSVsF samples with a wide range of IVRP values were generated by applying UV irradiation (photo) and high temperature (heat) induced stress for varying lengths of time. These samples were characterized in terms of stress induced modifications in primary and secondary structures as well as aggregation of RSVsF. Immunogenicity, also referred to as In vivo potency, was measured by induction of total F-protein specific IgG and RSV-neutralizing antibodies in mice dosed with these RSVsF samples. Comparison of results between IVRP and these immunogenicity assays revealed that IVRP provided a sensitive read-out of the integrity of epitope sites A and C, and a conservative and reliable evaluation of the potency of RSVsF as a vaccine antigen. This high throughput and fast turn around assay allowed us to efficiently screen many different RSVsF antigen lots, thereby acting as an effective filter for ensuring high quality antigen that delivered in vivo potency. In vitro and in vivo potencies were further probed at the level of individual epitope sites, A and C. Results of these experiments indicated that site A was relatively resistant to stress induced loss of potency, in vitro or in vivo, compared to site C. PMID- 29456017 TI - Myocarditis and pericarditis are rare following live viral vaccinations in adults. AB - Reports of myocarditis and pericarditis following smallpox vaccination in adults suggested a need to assess inflammatory cardiac disease risk among adults who receive live viral vaccinations. From 1996 through 2007, among 416,629 vaccinated adults in the Vaccine Safety Datalink, we identified one probable pericarditis case and no cases of myocarditis in the 42 days following a live viral vaccination. Our self-controlled risk interval analysis found that, based on one case identified during the risk interval and 10 cases during the control interval, there is no increased risk of myopericarditis in the 42 days following vaccination (IRR, 0.57; 95% CI, 0.07, 4.51). Our study suggests that the occurrence of myopericarditis following live viral vaccination is rare with an estimated incidence of 0.24 per 100,000 vaccinated, which is not higher than the background rate and is much lower than the incidence rates reported following smallpox vaccination.

AB - Chemoresistance is one of the causes of adverse effects in gastric cancer, including a poor response to cisplatin (DDP). Exosomes loaded with microRNA (miRNA), mRNA, and other non-coding RNAs could regulate drug resistance. Exo-anti 214 was extracted and verified. A Cell Counting Kit-8 (CCK-8) cell viability assay, flow cytometry, and transwell and immunofluorescence assays were performed to determine whether exo-anti-214 could sensitize cells to DDP in vitro. A combination of intravenously injected exo-anti-214 and intraperitoneal DDP was utilized in vivo. Additionally, potential targets of miR-214 were screened by mass spectrometry (MS) and confirmed via western blotting (WB). The levels of miR 214 in the human immortalized gastric epithelial cell line ges-1 and the human gastric adenocarcinoma cell lines SGC7901 and SGC7901/DDP gradually increased. Exo-anti-214 could fuse with cells and regulate potential targets, reducing cell viability, suppressing migration, and promoting apoptosis in vitro. Caudally injected exo-anti-214 was applied to reverse chemoresistance and repress tumor growth in vivo due to the downregulation of miR-214 and overexpression of possible target proteins in tumors. Exo-anti-214 could reverse the resistance to DDP in gastric cancer, which might serve as a potential alternative for the treatment of cisplatin-refractory gastric cancer in the future. PMID- 29456020 TI - Advanced siRNA Designs Further Improve In Vivo Performance of GalNAc-siRNA Conjugates. AB - Significant progress has been made in the advancement of RNAi therapeutics by combining a synthetic triantennary N-acetylgalactosamine ligand targeting the asialoglycoprotein receptor with chemically modified small interfering RNA (siRNA) designs, including the recently described Enhanced Stabilization Chemistry. This strategy has demonstrated robust RNAi-mediated gene silencing in liver after subcutaneous administration across species, including human. Here we demonstrate that substantial efficacy improvements can be achieved through further refinement of siRNA chemistry, optimizing the positioning of 2'-deoxy-2' fluoro and 2'-O-methyl ribosugar modifications across both strands of the double stranded siRNA duplex to enhance stability without compromising intrinsic RNAi activity. To achieve this, we employed an iterative screening approach across multiple siRNAs to arrive at advanced designs with low 2'-deoxy-2'-fluoro content that yield significantly improved potency and duration in preclinical species, including non-human primate. Liver exposure data indicate that the improvement in potency is predominantly due to increased metabolic stability of the siRNA conjugates.

AB - Canavan disease, a leukodystrophy caused by loss-of-function ASPA mutations, is characterized by brain dysmyelination, vacuolation, and astrogliosis ("spongiform leukodystrophy"). ASPA encodes aspartoacylase, an oligodendroglial enzyme that cleaves the abundant brain amino acid N-acetyl-L-aspartate (NAA) to L-aspartate and acetate. Aspartoacylase deficiency results in a 50% or greater elevation in brain NAA concentration ([NAAB]). Prior studies showed that homozygous constitutive knockout of Nat8l, the gene encoding the neuronal NAA synthesizing enzyme N-acetyltransferase 8-like, prevents aspartoacylase-deficient mice from developing spongiform leukodystrophy. We now report that brain Nat8l knockdown elicited by intracerebroventricular/intracisternal administration of an adeno associated viral vector carrying a short hairpin Nat8l inhibitory RNA to neonatal aspartoacylase-deficient AspaNur7/Nur7 mice lowers [NAAB] and suppresses development of spongiform leukodystrophy.

AB - Structured mRNAs positioned downstream of the ribosomal decoding center alter gene expression by slowing protein synthesis. Here, we solved the cryo-EM structure of the bacterial ribosome bound to an mRNA containing a 3' stem loop that regulates translation. Unexpectedly, the E-site tRNA adopts two distinct orientations. In the first structure, normal interactions with the 50S and 30S E site are observed. However, in the second structure, although the E-site tRNA makes normal interactions with the 50S E site, its anticodon stem loop moves ~54 A away from the 30S E site to interact with the 30S head domain and 50S uL5. This position of the E-site tRNA causes the uL1 stalk to adopt a more open conformation that likely represents an intermediate state during E-site tRNA dissociation. These results suggest that structured mRNAs at the entrance channel restrict 30S subunit movement required during translation to slow E-site tRNA dissociation.

AB - PURPOSE: To investigate changes induced in mouse intestines after irradiation and to explore the potential radioprotective effects of flagellin A N/C (FlaAN/C). METHODS AND MATERIALS: A mouse model of radiation-induced enteropathy was used in this study. A 10-Gy abdominal irradiation was performed on FlaAN/C- and vehicle injected mice to explore the role of FlaAN/C in intestinal radiation injury and to study the molecular mechanism in this process. In the intestinal tissue, pathologic changes were investigated by hematoxylin and eosin staining, TUNEL staining, and immunohistochemistry; Western blotting and quantitative reverse transcription-polymerase chain reaction were used to determine the changes in protein and messenger RNA levels, respectively; and an enzyme-linked immunosorbent assay was performed to determine protein concentration in serum. The involvement of the reactive oxygen species pathway was investigated by determining superoxide dismutase, glutathione (GSH) peroxidase, GSH reductase, and GSH disulfide (GSSG) plus GSH activities. RESULTS: Flagellin A N/C inhibited radiation-induced reactive oxygen species production, decreased NLRP3 activity, and reduced the occurrence of caspase-1-dependent pyroptosis. The results revealed that oxidative stress, bioenergetic impairment, and subsequent NLRP3 inflammasome activation were involved in radiation-induced intestinal injury. Flagellin A N/C exerted a protective effect by blunting the activation of NLRP3 inflammasome signaling, thereby reducing the inflammatory response and occurrence of caspase-1-dependent pyroptosis in the intestine. Therefore, treatment of mice with FlaAN/C reduced radiation-induced intestinal injury. CONCLUSIONS: Reactive oxygen species-induced NLRP3 inflammasomes mediated radiation-induced pyroptosis of the intestinal cells, and FlaAN/C suppressed pyroptosis to protect the intestinal tissue. These results provide novel insights into the mechanisms underlying radiation-induced cytotoxicity, and FlaAN/C might be a potential preventive therapy for radiation-induced intestinal injury in patients with cancer. PMID- 29456025 TI - Effectiveness of User- and Expert-Driven Web-based Hypertension Programs: an RCT. AB - INTRODUCTION: The effectiveness of self-guided Internet-based lifestyle counseling (e-counseling) varies, depending on treatment protocol. Two dominant procedures in e-counseling are expert- and user-driven. The influence of these procedures on hypertension management remains unclear. The objective was to assess whether blood pressure improved with expert-driven or user-driven e counseling over control intervention in patients with hypertension over a 4-month period. STUDY DESIGN: This study used a three-parallel group, double-blind randomized controlled design. SETTING/PARTICIPANTS: In Toronto, Canada, 128 participants (aged 35-74 years) with hypertension were recruited. Participants were recruited using online and poster advertisements. Data collection took place between June 2012 and June 2014. Data were analyzed from October 2014 to December 2016. INTERVENTION: Controls received a weekly e-mail newsletter regarding hypertension management. The expert-driven group was prescribed a weekly exercise and diet plan (e.g., increase 1,000 steps/day this week). The user-driven group received weekly e-mail, which allowed participants to choose their intervention goals (e.g., [1] feel more confident to change my lifestyle, or [2] self-help tips for exercise or a heart healthy diet). MAIN OUTCOME MEASURES: Primary outcome was systolic blood pressure measured at baseline and 4-month follow-up. Secondary outcomes included cholesterol, 10-year Framingham cardiovascular risk, daily steps, and dietary habits. RESULTS: Expert-driven groups showed a greater systolic blood pressure decrease than controls at follow-up (expert-driven versus control: -7.5 mmHg, 95% CI= -12.5, -2.6, p=0.01). Systolic blood pressure reduction did not significantly differ between user- and expert-driven. Expert driven compared with controls also showed a significant improvement in pulse pressure, cholesterol, and Framingham risk score. The expert-driven intervention was significantly more effective than both user-driven and control groups in increasing daily steps and fruit intake. CONCLUSIONS: It may be advisable to incorporate an expert-driven e-counseling protocol in order to accommodate participants with greater motivation to change their lifestyle behaviors, but more studies are needed. TRIAL REGISTRATION: This study is registered at www.clinicaltrials.gov NCT03111836. PMID- 29456027 TI - Enhanced chondrogenesis differentiation of human induced pluripotent stem cells by MicroRNA-140 and transforming growth factor beta 3 (TGFbeta3). AB - Induced pluripotent stem cells (iPSCs) make an attractive source for regenerative medicine. The objective of our study was to establish a new method for differentiation of human iPSCs toward chondrocyte by overexpression of MicroRNA 140 (miR-140) and use of transforming growth factor beta 3 (TGFbeta3) in high cell density culture systems. We prepared vectors and then was used for recombinant Lenti virus production in HEK-293 cell. Transducted cells were selected and cultured in pellet culture system and were harvested after days 7, 14 and 21. Real-time PCR was performed to evaluate the cartilage-specific genes in the mRNA levels. Also, in order to confirm our results, we have done immunological assay. iPSCs were transducted with recombinant Lenti virus and miR 140 was expressed. Immunological methods confirmed that differentiation of iPSC toward chondrocyte with handling cartilage matrix genes. Also real time PCR demonstrated that in transducted iPSCs significantly increased gene expression of collagen type II, SOX9 and aggrecan, and down-regulated expression of collagen type I when compared to the mRNA levels measured in non transducted iPSCs. In Conclusion, our data implies that miR-140 is a potent chondrogenic differentiation inducer for iPSCs and also, we have showed increasing chondrogenic differentiation by using overexpression of miR-140 and TGFbeta3. PMID- 29456026 TI - Neural Population Dynamics Underlying Motor Learning Transfer. AB - Covert motor learning can sometimes transfer to overt behavior. We investigated the neural mechanism underlying transfer by constructing a two-context paradigm. Subjects performed cursor movements either overtly using arm movements, or covertly via a brain-machine interface that moves the cursor based on motor cortical activity (in lieu of arm movement). These tasks helped evaluate whether and how cortical changes resulting from "covert rehearsal" affect overt performance. We found that covert learning indeed transfers to overt performance and is accompanied by systematic population-level changes in motor preparatory activity. Current models of motor cortical function ascribe motor preparation to achieving initial conditions favorable for subsequent movement-period neural dynamics. We found that covert and overt contexts share these initial conditions, and covert rehearsal manipulates them in a manner that persists across context changes, thus facilitating overt motor learning. This transfer learning mechanism might provide new insights into other covert processes like mental rehearsal.

PMID- 29456028 TI - Polyphasic characterization of a novel species in the Lactobacillus casei group from cow manure of Taiwan: Description of L. chiayiensis sp. nov. AB - Two Gram-stain-positive, rod-shaped, non-motile, catalase-negative and facultative anaerobic strains, NCYUAST and BCRC 18859 (=NRIC 1947), were isolated from cow manure of Taiwan and coconut juice of Philippines, respectively. Comparative sequence analysis of 16S rRNA gene revealed that the novel strains were members of the genus Lactobacillus. These two strains had 100% of 16S rRNA gene sequence similarity and 98.6% of average nucleotide identity (ANI) value based on whole genome sequences. On the basis of 16S rRNA gene sequence similarity, the type strains of Lactobacillus casei (99.6% similarity), Lactobacillus paracasei subsp. paracasei (99.1%), L. paracasei subsp. tolerans (99.1%), Lactobacillus rhmnosus (99.0%) and 'Lactobacillus zeae' (99.7%) were the closest neighbors to these novel strains. The results of phenotypic and chemotaxonomic characterization, multilocus sequence analysis (MLSA) based on the sequences of three housekeeping genes (dnaK, pheS and yycH), whole-genome sequence (WGS)-based comparison by ANI and in silico DNA-DNA hybridization (isDDH), species-specific PCR and whole-cell MALDI-TOF MS spectral pattern analyses demonstrated that the novel two strains represented a single, novel species within the L. casei group, for which the name Lactobacillus chiayiensis sp. nov., is proposed. The type strain is NCYUAST (=BCRC 81062T=NBRC 112906T). PMID- 29456030 TI - Acute phase nutritional screening tool associated with functional outcomes of hip fracture patients: A longitudinal study to compare MNA-SF, MUST, NRS-2002 and GNRI. AB - BACKGROUND & AIMS: Several hip fracture patients are malnourished, but no study has attempted to determine the optimal nutritional screening tool for predicting functional outcomes. We investigated the association between each nutritional status assessed by four nutritional screening tools at admission and functional outcomes during the postoperative acute phase in hip fracture patients. METHODS: The Mini Nutritional Assessment-Short Form (MNA-SF), the Malnutrition Universal Screening Tool (MUST), the Nutritional Risk Score 2002 (NRS-2002) and the Geriatric Nutritional Risk Index (GNRI) were assessed at admission before surgery. We evaluated the motor domain of the functional independence measure (motor-FIM) score at discharge, efficiency on the motor-FIM (change in the motor FIM score after postoperative rehabilitation divided by postoperative length of hospital stay), and 10-m walking speed at postoperative 14 days as functional outcomes. RESULTS: Two hundred and five patients (mean patient age, 83.5 +/- 7.0 years; range, 65-100 years; 82% female) were included. The MNA-SF evaluation classified 56 patients as well-nourished, 103 as at risk of malnutrition and 46 as malnourished. The MUST evaluation classified 97 patients as low risk, 42 as medium risk and 66 as high risk. The NRS-2002 evaluation classified 89 patients as well-nourished, 69 as medium risk and 47 as nutritionally at risk. The GNRI evaluation classified 44 patients as no risk, 74 as low risk and 87 as a major risk. Multiple linear regression analysis revealed that MNA-SF had a significant association with discharge motor-FIM (well-nourished vs. at risk of malnutrition, standardised beta = -0.06, p = 0.04; vs. malnourished, standardised beta = -0.32, p < 0.01), efficiency on the motor-FIM (well-nourished vs. malnourished, standardised beta = -0.19, p = 0.02) and 10-m walking speed (well-nourished vs. malnourished, standardised beta = -0.30, p < 0.01). The GNRI was significantly associated with 10-m walking speed (no risk vs. mild risk, standardised beta = 0.23, p = 0.02; vs. major risk, standardised beta = -0.37, p < 0.01), but not of motor-FIM and efficiency on the motor-FIM. No significant relationships were found among MUST and NRS-2002 and any functional outcomes. CONCLUSIONS: The MNA SF was found to be an optimal nutritional screening tool to associate with functional outcomes during the postoperative acute phase of elderly hip fracture patients.

PMID- 29456033 TI - Ecostructuring of marine nematode communities by submarine groundwater discharge. AB - Inputs of submarine groundwater discharge (SGD) to the coastal ocean may alter local and regional-scale biology. Here, we report on nematode assemblages along the north shore of Long Island, NY. We test if nematode communities differed between sites impacted by mixed fresh-saline SGD and where SGD is exclusively saline. Diversity of nematodes was low at sites impacted by fresh SGD and communities were dominated by a few opportunistic genera. Moreover, a set of typical freshwater nematode genera restricted to impacted sites was observed. Their presence in the marine coastal zone is exceptional and underlines the structuring role that fresh SGD plays in the local ecosystem. Saline SGD structured nematode assemblages differently compared to sites impacted by fresh SGD. The number of nematode genera was markedly higher at saline SGD sites, with a different community structure. This study highlights the importance to which inputs of fresh SGD may have on local ecosystem diversity in marine coastal environments. PMID- 29456034 TI - Cryopreservation and storage of cat epididymal sperm using -75 degrees C freezer vs liquid nitrogen. AB - The quality of cat epididymal sperm cryopreserved and stored by four methods was assessed. Epididymal sperm were suspended in Tris-glucose-citrate egg yolk extender, loaded in 0.25 mL straws and then cryopreserved. The samples in a standard protocol (LN) were cryopreserved and stored in liquid nitrogen (LN2). The sperm straws in the LN-Fr-LN group were cryopreserved in LN2 and stored in a 75 degrees C freezer; the straws were returned to LN2 prior to thawing. The loaded straws in the Fr group were transferred directly from 4 degrees C to the freezer and maintained in the freezer until thawing. The Fr-LN samples were cryopreserved and stored in the freezer and were introduced into LN2 before thawing. The sperm thawing was conducted on days 30, 60, 90 and 120 of cryopreservation. The sperm motility, viability, membrane integrity and acrosome integrity were evaluated at 15 and 180 min after thawing. The quality of post thaw sperm in all three modified protocols was comparable (P > 0.05) and did not differ from that in the standard protocol except the membrane integrity of the 60 days stored samples evaluated at 15 min after thawing, which was significantly higher for the LN-Fr-LN than the Fr-LN groups (P = 0.04). The length of cryopreservation time had no effect (P > 0.05) on the sperm parameters assessed at 15 min after thawing. The sperm motility was significantly greater (P = 0.01 to P = 0.02) for the 15 min than the 180 min incubation. In conclusion, cat epididymal sperm could alternatively be cryopreserved and/or stored by using the 75 degrees C freezer for 120 days. To use, the cryopreserved sperm in the freezer could be thawed immediately or after being transferred to LN2. This was useful for the application of the -75 degrees C cryopreserved sperm in remote areas. PMID- 29456035 TI - A Comparison of the Efficacy of Immunomodulatory-containing Regimens in Relapsed/Refractory Multiple Myeloma: A Network Meta-analysis. AB - BACKGROUND: Previous network meta-analyses combined studies of immunomodulatory drug (IMiD)-containing and IMiD-free regimens, despite a lack of head-to-head randomized controlled trials to robustly link them. However, patients with relapsed or refractory multiple myeloma (RRMM) treated with IMiD-containing regimens differ from those treated with IMiD-free regimens, especially relating to treatment history, which is an important treatment-effect modifier requiring clinical consideration when evaluating the most appropriate subsequent treatment options. A need exists to separately assess the efficacy of treatment regimens for patients who are suitable candidates for IMiD-containing and IMiD-free regimens. The presented analyses will enable clinicians to assess the best regimens to use in patients suitable for IMiD-containing regimens. MATERIALS AND METHODS: We used a Bayesian network meta-analysis to compare IMiD-containing regimens in patients with RRMM. Additionally, subgroup analyses were conducted stratified by previous therapy line, previous bortezomib therapy, and previous lenalidomide therapy. RESULTS: The results indicated that triplet combinations are more effective than doublet combinations. Of the triplet combinations, daratumumab, lenalidomide, dexamethasone (DRd) was significantly better in improving progression-free survival in patients with RRMM than were other IMiD containing regimens (lenalidomide, dexamethasone [Rd]: hazard ratio [HR], 0.37; carfilzomib, Rd: HR, 0.54; elotuzumab, Rd: HR, 0.54; ixazomib, Rd: HR, 0.50). Similar trends were observed for overall survival and overall response. DRd showed the greatest probability of being the best treatment for all clinical efficacy outcomes. The subgroup analyses results were consistent with the base case results. CONCLUSION: In patients with RRMM who are suitable for an IMiD containing regimen, DRd showed clear advantages in survival and response outcomes compared with other IMiD-containing regimens. PMID- 29456036 TI - Diagnostic criteria for acute food protein-induced enterocolitis syndrome. Is the work in progress? AB - Food protein-induced enterocolitis syndrome (FPIES) is a non IgE-mediated gastrointestinal food allergic disorder. Some diagnostic criteria have been published for acute FPIES. Of course, they are not all the same, so the clinician must choose which ones to adopt for his/her clinical practice. We present here a brief review of these criteria and, through two clinical cases, show how the choice of one or the other can change the diagnostic destiny of a child with suspect FPIES. PMID- 29456037 TI - Evaluation of an intervention to improve the management of allergens in school food services in the city of Barcelona. AB - BACKGROUND: An intervention to promote the development of an allergen control plan (ACP) and preventive measures for the management of allergens in school food services was implemented in all schools of Barcelona city over a three-year period (2013-2015) by the public health services. The present study aimed to assess changes regarding the management of food allergens in school food services in Barcelona after an intervention conducted by the public health services of the city. METHODS: School meal operators of a random sample of 117 schools were assessed before and after the intervention using a structured questionnaire. The questionnaire collected general information on the students and their demand for special menus, and included 17 closed questions regarding the implementation of specific preventive measures for the management of allergens. Based on these 17 questions, a food safety score was calculated for each school. The improvement in these scores was evaluated. RESULTS: The results showed positive increments in the percentage of implementation of 12 of the 17 preventive measures assessed. The percentage of school food services with an implemented ACP increased by 49%. Schools with external and internal food supplies increased their scores by 16.5% and 19.6%, respectively. The greatest improvements were observed in smaller food services and in schools located in districts with low gross household incomes. CONCLUSIONS: The intervention was effective in improving school food services' management of allergens and in reducing the differences found among food services in the pre-intervention survey. We must also focus efforts on reducing socio economic inequalities linked to the management of allergens. PMID- 29456038 TI - Increase of natural killer cells in children with liver transplantation-acquired food allergy. AB - BACKGROUND: Transplantation-acquired food allergies (TAFA) are frequently reported and considered to be caused by immunosuppressive therapy. The aim of this study was to investigate the allergic and immunologic responses in children who had liver or kidney transplantations. METHODS: Twelve children receiving liver transplantations and 10 children receiving kidney transplantations were investigated. All children underwent the allergy work-up and in most of them, lymphocyte screening and serum cytokine measurements were also performed. RESULTS: TAFA were found in 7/12 (58%) children with liver transplantations and in none of the 10 children with kidney transplantations. The mean age at transplantation was significantly lower in children who underwent liver transplantations (p<0.001). The immunosuppressive therapy administered to children with liver transplantation was tacrolimus in 11 patients and cyclosporine in one patient, while all 10 children with kidney transplantation received tacrolimus plus mycophenolate. The most common antigenic food was egg. The natural killer (NK) cell numbers were significantly higher in liver transplant children than in kidney-transplant children. No significant differences were found in the serum cytokine levels. CONCLUSIONS: This study confirms that liver-transplant children treated with tacrolimus alone have a higher risk of developing TAFA than kidney-transplant children treated with tacrolimus plus mycophenolate. NK cells might be involved in this difference. PMID- 29456039 TI - Exposure to dogs but not cats is associated to a decrease in the prevalence in atopic dermatitis amongst school-children. AB - INTRODUCTION: The association regarding the exposure to pets, especially cats and dogs, and the prevalence of allergic diseases is inconsistent. OBJECTIVE: We analyzed the role played by early exposure to dogs or cats in the prevalence of allergic diseases amongst school-aged children. METHOD: Through a cross-sectional study, we examined 756 children, aged 6-7; these candidates were selected through cluster sampling. We inquired about the exposure that these children had had to dogs and cats, and whether these pets spent most of their time indoors or outdoors during the first year of the child's life. In order to identify the prevalence of allergic diseases and their symptoms, each child's parent completed the International Study of Asthma and Allergies in Childhood questionnaire. RESULTS: Exposure to outdoor dogs was associated to nocturnal coughing, odds ratio (OR) 0.64, with a confidence interval of 95% (95% CI) 0.43-0.95 and with atopic dermatitis (OR: 0.39; 95% CI: 0.20-0.76). Interestingly, exposure to outdoor cats was associated to nocturnal coughing (OR: 0.51; 95% CI: 0.32-0.83) and current rhinitis symptoms (OR: 0.59; 95% CI 0.36-0.97). After carrying out the multivariate analyses, only exposure to dogs, both indoor and outdoor, was significantly associated to a decrease in the prevalence of atopic dermatitis OR 0.40 (95% CI: 0.20-0.79) and OR 0.38 (95% CI: 0.18-0.83), respectively. CONCLUSION: Our findings suggest that exposure to dogs, whether they be indoor or outdoor pets, is associated to a decreased prevalence in atopic dermatitis. PMID- 29456040 TI - A very rare case of renal cell carcinoma metastasis to spermatic cord and a condensed literature review. AB - INTRODUCTION: Renal cell carcinoma (RCC) is proved to be the ninth most common malignancy. Two-third of the patients suffering from RCC will present metastases. Secondary metastases of RCC to spermatic cord are very rare. PRESENTATION OF CASE: In this report we present the case of a patient with renal cell carcinoma with metachronous metastasis to the spermatic cord occurring two years after the initial diagnosis of the disease. DISCUSSION: Our patient was treated according to EAU guidelines. The metastatic tumor was diagnosed accidentally, in contrast to the previous follow-up exams which show no disease in the meantime. Moreover, the histological examination of the spermartic cord tumor illustrated tumor thrombus. The former examination results along with the anatomical and embryological relations of renal and spermatic cord structures indicate a hypothesis about the mechanism of this metastasis' route. CONCLUSION: Our case is of great interest, since such cases are very few in the international literature. Therefore the presentation of this case as well as its implications should be made to the global surgery community.

AB - Mesoporous silica nanoparticles (MSNs) were functionalized with amino groups (MSN NH2) and then with hyaluronic acid, a biocompatible biopolymer which can be recognized by CD44 receptors in tumor cells, to obtain a targeting drug delivery system. To this purpose, three hyaluronic acid samples differing for the molecular weight, namely HAS (8-15 kDa), HAM (30-50 kDa) and HAL (90-130 kDa), were used. The MSN-HAS, MSN-HAM, and MSN-HAL materials were characterized through zeta potential and dynamic light scattering measurements at pH = 7.4 and T = 37 degrees C to simulate physiological conditions. While zeta potential showed an increasing negative value with the increase of the HA chain length, an anomalous value of the hydrodynamic diameter was observed for MSN-HAL, which was smaller than that of MSN-HAS and MSN-HAM samples. The cellular uptake of MSN-HA samples on HeLa cells at 37 degrees C was studied by optical and electron microscopy. HA chain length affected significantly the cellular uptake that occurred at a higher extent for MSN-NH2 and MSN-HAS than for MSN-HAM and MSN-HAL samples. Cellular uptake experiments carried out at 4 degrees C showed that the internalization process was inhibited for MSN-HA samples but not for MSN-NH2. This suggests the occurrence of two different mechanisms of internalization. For MSN-NH2 the uptake is mainly driven by the attractive electrostatic interaction with membrane phospholipids, while MSN-HA internalization involves CD44 receptors overexpressed in HeLa cells. PMID- 29456043 TI - Colistin alone versus colistin plus meropenem for treatment of severe infections caused by carbapenem-resistant Gram-negative bacteria: an open-label, randomised controlled trial. AB - BACKGROUND: Colistin-carbapenem combinations are synergistic in vitro against carbapenem-resistant Gram-negative bacteria. We aimed to test whether combination therapy improves clinical outcomes for adults with infections caused by carbapenem-resistant or carbapenemase-producing Gram-negative bacteria. METHODS: A randomised controlled superiority trial was done in six hospitals in Israel, Greece, and Italy. We included adults with bacteraemia, ventilator-associated pneumonia, hospital-acquired pneumonia, or urosepsis caused by carbapenem-non susceptible Gram-negative bacteria. Patients were randomly assigned (1:1) centrally, by computer-generated permuted blocks stratified by centre, to intravenous colistin (9-million unit loading dose, followed by 4.5 million units twice per day) or colistin with meropenem (2-g prolonged infusion three times per day). The trial was open-label, with blinded outcome assessment. Treatment success was defined as survival, haemodynamic stability, improved or stable Sequential Organ Failure Assessment score, stable or improved ratio of partial pressure of arterial oxygen to fraction of expired oxygen for patients with pneumonia, and microbiological cure for patients with bacteraemia. The primary outcome was clinical failure, defined as not meeting all success criteria by intention-to-treat analysis, at 14 days after randomisation. This trial is registered at ClinicalTrials.gov, number NCT01732250, and is closed to accrual. FINDINGS: Between Oct 1, 2013, and Dec 31, 2016, we randomly assigned 406 patients to the two treatment groups. Most patients had pneumonia or bacteraemia (355/406, 87%), and most infections were caused by Acinetobacter baumannii (312/406, 77%). No significant difference between colistin monotherapy (156/198, 79%) and combination therapy (152/208, 73%) was observed for clinical failure at 14 days after randomisation (risk difference -5.7%, 95% CI -13.9 to 2.4; risk ratio [RR] 0.93, 95% CI 0.83-1.03). Results were similar among patients with A baumannii infections (RR 0.97, 95% CI 0.87-1.09). Combination therapy increased the incidence of diarrhoea (56 [27%] vs 32 [16%] patients) and decreased the incidence of mild renal failure (37 [30%] of 124 vs 25 [20%] of 125 patients at risk of or with kidney injury). INTERPRETATION: Combination therapy was not superior to monotherapy. The addition of meropenem to colistin did not improve clinical failure in severe A baumannii infections. The trial was unpowered to specifically address other bacteria. FUNDING: EU AIDA grant Health-F3-2011 278348. PMID- 29456045 TI - Hepatectomy for octogenarians with colorectal liver metastasis in the era of enhanced recovery. AB - BACKGROUND: Concern exists regarding the use of hepatectomy to treat colorectal liver metastasis (CRLM) in octogenarians due to prior studies suggesting elevated morbidity and mortality. Cardiopulmonary exercise testing (CPET) within pre operative assessment and enhanced recovery after surgery (ERAS) have both been shown to be associated with low morbidity and mortality in patients undergoing hepatectomy. This study sought to compare the outcomes of octogenarians with patients aged 70-79 undergoing hepatectomy for CRLM, within a center utilizing both CPET and ERAS. METHODS: Consecutive patients age 70 or older who underwent hepatectomy for CRLM at Aintree University Hospital (Liverpool,UK), between May 2008 and May 2015 were identified from a prospectively maintained cancer database. Data were extracted and comparisons drawn. RESULTS: 127 patients aged 70-79 years and 34 octogenarians underwent respectively 137 and 35 hepatectomy for CRLM. There was no difference in hospital stay (6 days), morbidity and mortality between the groups. OS at 1, 3 and 5 years were 86.7%, 55% and 35.8% for those aged 70-79 compared to 79.4%, 37.3% and 20.4% for the octogenarians (p=0.127). DFS at 1,3 and 5 years was 52.5%, 31.7% and 31.7% for 70-79 group compared to 46.2%, 31.5% and 16.8% for the octogenarians (p=0.838). On multivariate analysis major hepatectomy was associated with an increased risk of post-operative complications, inferior OS and DFS. Chronological age was not a predictor of postoperative complications, poorer OS or DFS. CONCLUSIONS: Appropriately selected octogenarians can have similar postoperative outcomes to patients aged 70-79 when undergoing hepatectomy for CRLM using ERAS combined with CPET. This study advocates using CPET and ERAS in the selection and management of octogenarian patients with CRLM undergoing hepatectomy. PMID- 29456046 TI - The spectrum of "off" in Parkinson's disease: What have we learned over 40 years? AB - The terms "on" and "off" were used by Marsden and his contemporaries over 40 years ago to describe times when Parkinson's disease patients experienced good motor function ("on") and immobility ("off"). Yet there remains no published consensus definition of "off", leading clinicians and patients to develop individualized impressions of "off" determinations. In this paper, we first discuss the evolution of the terminology and understanding of "off" states since Marsden's time, which now include non-motor as well as motor symptoms. We then review pathophysiology and risk factors for the development of "off" states as well as tools to detect the "off" state, before proposing a practical definition of "off" for consideration.

PMID- 29456049 TI - Six-Month Outcomes After High-Risk Coronary Artery Bypass Graft Surgery and Preoperative Intra-aortic Balloon Counterpulsation Use: An Inception Cohort Study. AB - OBJECTIVE: To inform the design of a pivotal randomized controlled trial of prophylactic intra-aortic balloon counterpulsation (IABC) in patients undergoing coronary artery bypass graft (CABG) at high risk of postoperative low cardiac output syndrome (LCOS). DESIGN: Inception cohort study. SETTING: A total of 13 established cardiac centers in Australia, Canada, New Zealand, and the United Kingdom. PARTICIPANTS: Adult patients were eligible for inclusion if they were listed for CABG surgery and had 2 or more LCOS risk factors (low ejection fraction, severe left main coronary artery disease, redo sternotomy, unstable angina). INTERVENTIONS: Outcomes of interest were a composite outcome of in hospital mortality, postoperative acute myocardial infarction (AMI), acute kidney injury (AKI), or stroke as well as 6-month vital status and quality of life using the EuroQol 5-dimensional questionnaire (EQ5D). MEASUREMENTS AND MAIN RESULTS: The study included 136 participants over a 29-month period. Overall, in-hospital and 6-month mortality occurred in 7 (5%) and 11 (8%) participants, respectively. The composite outcome occurred in 60 (44%). The mean increase in EQ5D summary index at 6 months was 0.10 (standard deviation 0.24, p = 0.01). Perioperative AMI, AKI, or stroke significantly decreased the odds of a clinically meaningful improvement in quality of life (odds ratio 0.32; 95% confidence interval 0.13 0.79; p = 0.014). Preoperative IABC was used in 39 participants and did not predict postoperative outcomes. CONCLUSIONS: The study identified a group of patients at risk of LCOS in whom CABG surgery was associated with a substantial burden of perioperative morbidity. Preoperative IABC use was variable, supporting the need for further research. PMID- 29456050 TI - Blood Transfusions in Cardiac Surgery: Balancing Science and Art.

PMID- 29456052 TI - Performance of a highly successful outbreak strain of Mycobacterium tuberculosis in a multifaceted approach to bacterial fitness assessment. AB - Determining bacterial fitness represents a major challenge and no single parameter can accurately predict the ability of a certain pathogen to succeed. The M strain of Mycobacterium tuberculosis managed to spread and establish in the community and caused the largest multidrug-resistant tuberculosis outbreak in Latin America. We have previously shown that the M strain can manipulate the host immune response, but we still have no direct evidence, other than epidemiology, that can account for the enhanced fitness of the M strain. Our objective was to further characterize the performance of the outbreak strain M in different fitness assays. Two main aspects were evaluated: (1) molecular characterization of selected isolates from the M outbreak and related strains and (2) comparative fitness and in vivo performance of representative M strain isolates vs. the non prosperous M strain variant 410. Our approach confirmed the multifaceted nature of fitness. Altogether, we conclude that the epidemiologically abortive strain 410 was vulnerable to drug-driven pressure, a weak competitor, and a stronger inductor of protective response in vivo. Conversely, the isolate 6548, representative of the M outbreak peak, had a growth disadvantage but performed very well in competition and induced lung damage at advanced stages in spite of reaching relatively low CFU counts. Integration of these observations supports the idea that the M strain managed to find a unique path to success. PMID- 29456053 TI - Conjoint Analysis of Treatment Preferences for Nondisplaced Scaphoid Fractures. AB - PURPOSE: We used conjoint analysis to assess the relative importance of factors that influence a patient's decision between surgical or nonsurgical management of a nondisplaced scaphoid fracture. Our hypothesis was that out-of-pocket costs will have a greater influence on decision making than the time spent in a cast or brace, degree of soreness, or the risk of treatment failure. METHODS: Two-hundred and fifty participants were recruited using Amazon Mechanical Turk and asked to assume that they had experienced a nondisplaced scaphoid waist fracture. They then indicated their relative preferences among 13 pairs of alternatives with variations in the following attributes: time in a cast, time in a brace, duration of ongoing soreness, risk of treatment failure (by which we meant scaphoid nonunion), out-of-pocket costs based on estimates of direct costs ($500-2,500), and apprehension about surgery. A conjoint analysis was used to determine the relative importance of these factors when choosing between surgical or nonsurgical management. RESULTS: The factor with the greatest influence on treatment choice was the cost of the procedure. After assessing the respondent's apprehension to undergo surgery, a sensitivity analysis showed the proportion of respondents who would choose surgery given different outcomes. To make the predicted share of those who are "not worried" about surgery equal to those who are "somewhat worried" or "a little worried" would require that the cost of surgery increase by $2,700. In addition, 2 weeks in a cast, 3 weeks in a brace, 2 months of soreness, or a 2% increase in the risk of fracture nonunion generates the same surgical choice probability as a $2,000 increase in the out-of-pocket cost of surgery. CONCLUSIONS: As conceptualized in this conjoint analysis, out-of pocket costs and apprehension about surgery seem to have a greater impact on a decision for surgery than the time spent in a brace or cast and the risk of treatment failure.

PMID- 29456054 TI - The Relationship Between Serum Interleukin-1alpha and Asymptomatic Infrarenal Abdominal Aortic Aneurysm Size, Morphology, and Growth Rates. AB - OBJECTIVE/BACKGROUND: In a pilot study, a relationship between abdominal aortic aneurysm (AAA) diameter and serum interleukin (IL)-1alpha levels was reported, and that endothelial cell (EC) activation in vitro in response to serum from patients with AAA was blocked by anti-IL-1alpha antibodies. The aim of the present study was to further investigate the relationship between serum IL-1alpha and asymptomatic infrarenal AAA size, morphology, and growth rates. METHODS: Serum IL-1alpha was measured using enzyme linked immunosorbent assay in 101 patients with asymptomatic, infrarenal AAA and related to aneurysm size, morphology, and growth rates. RESULTS: IL-1alpha was measured in 101 patients. There was no statistically significant difference in mean age between men and women. IL-1alpha was detectable in 62.4% of patients; median IL-1alpha titre was 3.26 pg/mL. There was no statistically significant relationship between IL-1alpha and maximum AAA antero-posterior diameter as measured by ultrasound (p = .649), AAA morphology (aortic length [p = .394], sac [p = .369], and thrombus volume [p = .629]) as measured on computed tomography, absolute increase in AAA diameter (p = .214), or AAA growth rate (p = .230). CONCLUSION: IL-1alpha is detectable in the majority of patients with infrarenal AAA, but the cause and clinical significance of this novel observation remains unknown. PMID- 29456056 TI - A preliminary exploration of plain-film radiography in scapular dyskinesis evaluation. AB - BACKGROUND: Evaluation of scapular dyskinesis is of clinical interest because it is believed to be associated with pathologies of the shoulder. This study investigated the feasibility of plain-film radiography in evaluating scapular dyskinesis. METHODS: Subjects with unilateral disorders of the shoulder (n = 186) who underwent plain-film radiography of bilateral scapulae were divided into 4 categories of scapular dyskinesis patterns according to the Kibler classification and analyzed. Coracoid upward shift distance (CUSD), length of the scapular spine line (LSS), and scapular upward rotation angle (SURA) were measured on the radiographs. Intrarater and inter-rater reliability were tested, and the characteristics of these parameters in each type were analyzed. The differences (d) between bilateral scapulae (d-CUSD, d-LSS, and d-SURA) among the 4 categories were compared. RESULTS: Intrarater and inter-rater reliability were excellent for all parameters. Significant differences between the scapulae were observed in CUSD in type I and in LSS in type II categories. No significant difference in any of the parameters was found in type III. Compared with the other categories, d CUSD in type I and d-LSS in type II were significantly larger. The cutoff values of d-CUSD and d-LSS were 1.1 mm and 1.2 mm, respectively. No significant difference in d-SURA was found among the 4 categories. CONCLUSIONS: The measurement of CUSD, LSS, and SURA on plain-film radiography had excellent reliability. d-CUSD and d-LSS were characteristic parameters of type I and type II, respectively; however, type III had no distinguishing characteristics among the parameters.

PMID- 29456058 TI - Comparison of the 9-month intra-stent conditions and 2-year clinical outcomes after Resolute zotarolimus-eluting stent implantation between 3-month and standard dual antiplatelet therapy. AB - BACKGROUND: The use of short-duration dual antiplatelet therapy (DAPT) remains controversial. To investigate efficacy and safety of short-duration DAPT, we performed a detailed comparison of intra-stent conditions by optical coherence tomography (OCT) after second-generation drug-eluting stent implantation with short-term and standard DAPT. METHODS AND RESULTS: Eighty-two consecutive patients with stable angina pectoris who received Resolute zotarolimus-eluting stents (R-ZESs; Medtronic Cardiovascular, Santa Rosa, CA, USA) were enrolled. Patients were assigned to 3-month (3M group: 41 patients) and standard (standard group: 41 patients) DAPT. In the 3M group, clopidogrel was discontinued 3 months after stent implantation. In the standard group, DAPT was maintained until follow up OCT. At 9 months, neointimal proliferation was significantly larger in the 3M group, but there were no significant between-group differences in the proportion of uncovered and malapposed strut. The prevalence of abnormal intra-stent tissue (AIT) at 9 months was equivalent between groups. A multiple regression analysis revealed malapposition at 9 months as the strongest independent predictor of AIT at 9 months, and the prevalence of AIT was not associated with DAPT duration. Over 2 years, cardiac events were equal between groups; however, major bleeding was higher tendency in the standard group than in the 3M group. CONCLUSION: This OCT study indicated that reducing DAPT's duration may provide acceptable arterial healing in patients with implanted R-ZESs.

PMID- 29456060 TI - Association of TNF-alpha but not IL-1beta levels with the presence of Helicobacter pylori infection increased the risk of peptic ulcer development. AB - Peptic ulcer is a lesion in the mucosa of the digestive tract affecting many people all around the world. Recent investigations have indicated that produced inflammatory cytokines such as TNF-alpha and IL-1beta in response to gastric infection by Helicobacter pylori play an important role in the development of peptic ulcer. With regard to the significance of these cytokines in peptic ulcer development and the high prevalence of this disease in the developing countries, this study aimed to investigate the association of TNF-alpha and IL-1beta with peptic ulcer in the presence of H. pylori. This case-control study enrolled 61 patients with peptic ulcer disease (PUD) as cases and 59 people without peptic ulcer (NPUD) as controls. Blood samples and endoscopic biopsies were collected. H. pylori infection was confirmed by using rapid urease test (RUT), specific IgG measurement and histopathological examination. Then, IL-1beta and TNF-alpha levels were evaluated using enzyme linked immunosorbent assay (ELISA). The seropositivity of H. pylori was 62.5% in the studied population, while by considering RUT and histopathological examination along with specific-IgG antibody, H. pylori infection decreased to 56.7%. In addition, H. pylori infection was significantly (OR = 0.37; 95% CI = 0.17-0.82; P = .02) associated with peptic ulcer development. The TNF-alpha level in PUD and infected H. pylori subjects was significantly higher than that of control and un-infected H. pylori individuals. However, no significant difference of IL1beta level was observed between PUD and control groups as well as between H. pylori infected and un infected individuals. Interestingly, IL-1beta level in PUD patients without H. pylori infection was significantly higher than infected ones. Moreover, a significant correlation between specific-IgG antibody with TNF-alpha level was observed. Taken together, our results showed that increased level of TNF-alpha could probably play pivotal role in pathogenesis of peptic ulcer in the presence of H. pylori infection. These findings also highlighted the importance of IL 1beta in the absence of H. pylori infection in peptic ulcer development.

PMID- 29456062 TI - Value of double pedicled mucoperiosteal flaps for the prevention of restenosis in Draf IIb frontal sinusotomy. AB - INTRODUCTION: The extent of bone exposure is one of the major factors contributing to failure of endoscopic frontal sinusotomy procedures. Double flaps providing cover of exposed bone have already been described for Draf III procedures in a cadavre study using posterior and lateral pedicled nasoseptal flaps. As these flaps overlap on the septal side, they cannot be raised from the same nasal cavity in a Draf IIb procedure. We describe a new technique using 2 local mucoperiosteal flaps raised from the same side to entirely cover the bone margins exposed by Draf IIb frontal sinusotomy. SURGICAL TECHNIQUE: A left Draf IIb procedure was performed to drain a frontal mucocele. A posterior septoturbinal flap (PSTF) was raised to cover the posterior sinusotomy margin. A lateral pedicle nasoseptal flap (LNSF) was raised on the same side to cover the anterior margin. With a follow-up of 6 months, the Draf IIb cavity was fully patent and the flaps were well integrated. CONCLUSION: PSTF and LNSF flaps can be raised on the same side to cover the posterior and anterior margins of the Draf IIb frontal sinusotomy, respectively. PMID- 29456063 TI - Clinical Outcome of Arthroscopic Lateral Retinacular Release for Symptomatic Bipartite Patella in Athletes. AB - PURPOSE: To report the results of arthroscopic lateral retinacular release without excision of the accessory fragment for treatment of symptomatic bipartite patella with a minimum 2-year follow-up. METHODS: We retrospectively reviewed all cases of symptomatic type III bipartite patella confirmed by radiographs, computed tomography, and magnetic resonance imaging and treated with arthroscopic lateral release from 2005 to 2015. Patients with history of knee fractures or surgery, concomitant meniscal or anterior cruciate ligament (ACL) procedures, and severe arthritic changes of the patellofemoral joint were excluded. Patients were assessed by Kujala score, visual analog scale (VAS), Tegner Activity Scale (TAS), and time to return to sporting activities. RESULTS: Ten patients (11 knees) were clinically reassessed after 69.6 +/- 33.3 (range: 25-132; 95% confidence interval [CI]: 47.29-91.99) months from surgery. There was a significant improvement in Kujala (P < .05) and VAS scores (P < .05), and no differences were found between pre- and postoperative TAS scores (P > .05). No complications occurred during the follow-up period. All patients returned to sport after 42.3 +/- 11.3 (range: 30 60; 95% CI: 34.71-49.84) days after surgery. CONCLUSIONS: The arthroscopic lateral retinacular release of a symptomatic type III bipartite patella without excision of the accessory fragment allowed early return to sporting activities, with excellent symptom relief. Patients had significantly improved mean Kujala and VAS scores without a decrease in the mean TAS scores. LEVEL OF EVIDENCE: Level IV, case series. PMID- 29456064 TI - Triple-Loaded Suture Anchors Versus a Knotless Rip Stop Construct in a Single-Row Rotator Cuff Repair Model. AB - PURPOSE: To compare the biomechanical properties of single-row repair with triple loaded (TL) anchor repair versus a knotless rip stop (KRS) repair in a rotator cuff repair model. METHODS: Rotator cuff tears were created in 8 cadaveric matched-pair specimens and repaired with a TL anchor or KRS construct. In the TL construct, anchors were placed in the greater tuberosity and then all suture limbs were passed through the rotator cuff as simple sutures and tied. In the KRS construct, a 2-mm suture tape was passed through the tendon in an inverted mattress fashion, and a free suture was passed medial to the suture tape to create a rip-stop. Then, the suture tape and free suture were secured with knotless anchors. Displacement was observed with video tracking after cyclic loading, and specimens were loaded to failure. RESULTS: The mean load to failure was 438 +/- 59 N in TL anchor repairs compared with 457 +/- 110 N in KRS repairs (P = .582). The mean displacement with cyclic loading was 3.8 +/- 1.6 mm in TL anchor repairs versus 4.3 +/- 1.8 mm in the KRS group (P = .297). Mode of failure was consistent in both groups, with 6 of 8 failures in the TL anchor group and 7 of 8 failures in KRS group occurring from anchor pullout. CONCLUSIONS: There is no statistical difference in load to failure and cyclic loading between TL anchor and KRS single-row repair techniques. CLINICAL RELEVANCE: KRS repair technique may be an alternative method of repairing full-thickness supraspinatus tendon tears with a single-row construct. PMID- 29456065 TI - Endoscopy-Assisted Hallux Valgus Correction Provides Sustainable Long-Term >10 Year Outcomes. AB - PURPOSE: This study aims to review the long-term efficacy of the endoscopy assisted distal soft-tissue procedure (EDSTP) and to see whether operative correction can be maintained for >10 years. METHODS: All hallux valgus cases undergoing EDSTP from 2000 to 2006 were recruited. Preoperative, postoperative, and 10-year follow-up x-rays were analyzed. A pain score from the preoperative and >10-year follow-up was recorded. The American Orthopaedic Foot and Ankle Society (AOFAS) hallux score and Foot and Ankle Outcome Score (FAOS) were measured at the >10-year follow-up. RESULTS: A total of 85 cases met the inclusion criteria with an EDSTP performed between January 2000 and December 2006 and had a follow-up of >10 years. Hallux valgus angle corrected from 25.8 degrees to 11.2 degrees (P < .001), 1,2 intermetatarsal angle (1,2 IMA) improved from 13.5 degrees to 9.5 degrees (P < .001), and the tibial sesamoid position changed from 4 to 1 (P < .001). Pain improved from preoperative 6.5/10 to 0.5/10 (P < .001). AOFAS score was 93.5/100 at >10-year follow-up, and the FAOS was good in all 5 subcategories (range, 72.6-89.3). CONCLUSIONS: Our results show that the EDSTP has good early postoperative results that are maintained for >10 years. It provides good long-term radiological correction, in addition to lasting pain relief and great foot function, using only 5 incisions. LEVEL OF EVIDENCE: Level IV, case series. PMID- 29456066 TI - Slight Reduction in the Insertion Depth for an All-Suture Anchor Decreases Cyclic Displacement in the Shoulder Glenoid. AB - PURPOSE: To determine if the depth of anchor insertion affects the biomechanical performance of a 1.5-mm all-suture anchor in glenoid bone. METHODS: A 1.5-mm all suture anchor was tested in 8 matched pairs of human cadaver fresh-frozen glenoids. Anchors were inserted at 6 different locations and tested at 3 different depths: 21 mm (preset drilling depth), 17 mm, and 13 mm. Cyclic loading and destructive testing was performed. Displacement after 100 and 200 cycles, along with ultimate failure strength, was determined. RESULTS: After 100 and 200 cycles, anchors placed at 13 and 17 mm had undergone significantly less displacement than those at 21 mm (P < .05). No difference was observed in ultimate load to failure between anchors placed at 21 and 17 mm. However, the ultimate load to failure was significantly lower in anchors placed at 13 mm (P < .05). There were 5 clinical failures in anchors placed at 21 mm, one at 17 mm, and none at 13 mm. CONCLUSIONS: The 1.5-mm all-suture anchor tested in this study has an optimal insertion depth of 17 mm, 4 mm shallower than the preset drill depth. At the optimal insertion depth of 17 mm, it underwent significantly less displacement after cyclic loading without a reduction in the ultimate load to failure. CLINICAL RELEVANCE: Given the results of this study, the optimal insertion depth for this 1.5-mm all-suture anchor is 17 mm, 4 mm shallower than the preset drill depth. PMID- 29456067 TI - Revision Hip Arthroscopy After Labral Reconstruction Using Iliotibial Band Autograft: Surgical Findings and Comparison of Outcomes With Labral Reconstructions Not Requiring Revision. AB - PURPOSE: To determine the causes of revision hip arthroscopy in patients who underwent labral reconstruction and to compare outcomes of these patients with patients who did not require a revision following reconstruction. METHODS: Patients who underwent revision hip arthroscopy after previous labral reconstruction from 2006 to 2014 were included. Patients with less than 2-year follow-up, preoperative joint space of <=2 mm, or who underwent other reconstructive procedures at the time of labral reconstruction were excluded. Each patient was matched by year of surgery, age, gender, and the number of previous surgeries with 2 patients that underwent labral reconstruction but did not require a revision following the reconstruction. Preoperatively and at a minimum 2-year follow-up, outcome scores were collected including the Hip Outcome Score-Activities of Daily Living (HOS-ADL) and HOS-Sports Scale, modified Harris Hip Score, Western Ontario and McMaster Universities Index (WOMAC), the 12-Item Short Form Health Survey (SF-12) Physical Component Summary, and the patient satisfaction outcome were collected. Differences between the preoperative and the postoperative outcomes score of each patient in the 2 groups was assessed using the paired t test. The Mann-Whitney U test was used to compare the 2 groups. RESULTS: From 347 patients who underwent iliotibial band autograft labrum reconstruction from 2006 to 2014, 28 hips (8%) in 26 patients (18 females and 8 males) had revision arthroscopy after labral reconstruction. The mean age was 32 years (range: 16-64). The mean number of hip surgeries prior to the labral reconstruction was 1.9 +/- 1.2. The average time from the last labral reconstruction procedure to revision labral reconstruction was 27 months (range: 5-59). Procedures performed at revision included lysis of adhesions (100%), additional femoroacetabular impingement (FAI) correction (50%), ligamentum teres debridement (50%), psoas release (29%), labral augmentation or reconstruction (14%), and others. Following revision surgery after previous labral reconstruction, 4 patients (14%) underwent total hip arthroplasty and 2 (7%) patients required a subsequent revision arthroscopy (age 67 and 23) at 15 months and 16 months. The average follow-up time was 3.6 years +/- 1 year after revision following labral reconstruction and after labral reconstruction in the nonrevision group. No significant difference was detected in the outcome scores and postoperative satisfaction between the 2 groups. The HOS-ADL improved 16 points in the nonrevision group and 19 points in the revision group. CONCLUSIONS: Patients who underwent revision surgery after labral reconstruction were mostly female, with 2 or more surgeries prior to reconstruction, and 14% required THA and 7% had recurrent scarring. In those who did not fail, outcomes significantly improved and were similar with patients who did not need revision. Adhesions and residual FAI were the most common findings during revision labral reconstruction. LEVEL OF EVIDENCE: Level III, retrospective comparative study. PMID- 29456068 TI - Magnetic Resonance Imaging Diagnosis of Medial Meniscal Ramp Lesions in Patients With Anterior Cruciate Ligament Injuries. AB - PURPOSE: To prospectively evaluate the sensitivity and specificity of magnetic resonance imaging (MRI) for diagnosing ramp lesions, to compare them between 1.5- and 3-T MRI, and to evaluate whether bone contusion of the posterior lip of the medial tibial plateau was associated with ramp lesions. METHODS: For 155 knees that underwent primary ACL reconstruction, we prospectively examined for ramp lesions and medial meniscal body tears on MRI. MRI diagnosis of ramp lesions required high signal irregularity of the capsular margin or separation in the meniscocapsular junction of the medial meniscus posterior horn on sagittal images. Bone contusion of the posterior lip of the medial tibial plateau was verified in 105 knees with MRI performed within 6 weeks after injury. All ramp lesions were identified by transcondylar observation during surgery. The sensitivity and specificity of MRI for ramp lesions and body tears were measured. Furthermore, we evaluated whether bone contusion of the medial tibial plateau was associated with ramp lesions. The chi-square test was used for statistical analysis. RESULTS: During surgery, ramp lesions were observed in 46 knees and medial meniscal body tears were seen in 35 knees. The sensitivity of MRI for ramp lesions was 71.7% and specificity was 90.5%. The sensitivity for ramp lesions was significantly lower than that for meniscal body tears (94.3%) (P = .01). The sensitivity of 3-T MRI (83.3%) was superior to that of 1.5-T MRI (67.6%), but not significantly different. The incidence of bone contusions was not significantly different among ramp lesions (38.5%), body tears (40.0%), or no tears (30.5%). CONCLUSIONS: The sensitivity of MRI for diagnosing ramp lesions was significantly lower than that for medial meniscal body tears. Bone contusion of the posterior lip of the medial tibial plateau on MRI was not associated with ramp lesions. LEVEL OF EVIDENCE: Level III, comparative trial. PMID- 29456069 TI - Arthroscopic Superior Capsular Reconstruction With Acellular Dermal Allograft for the Treatment of Massive Irreparable Rotator Cuff Tears: Short-Term Clinical Outcomes and the Radiographic Parameter of Superior Capsular Distance. AB - PURPOSE: This outcome analysis presents 88 consecutive shoulders presenting with irreparable rotator cuff tears that we treated with arthroscopic superior capsular reconstruction (SCR) using an acellular dermal allograft. We also present the concept of superior capsular distance to quantitatively measure the decreased distance present upon restoration of superior capsular integrity. METHODS: A retrospective review was conducted of patients treated with arthroscopic SCR with a minimum 12-month follow-up. Outcome analysis was performed via an internet-based outcome-tracking system to evaluate visual analog scale (VAS) and American Shoulder and Elbow Surgeons (ASES) scores. Radiographic analysis of anteroposterior radiographs analyzed acromiohumeral interval and superior capsular distance. Digital dynamometric strength and functional range of motion assessments were also obtained. The main inclusion criteria for patients in this analysis was all patients who underwent superior capsular reconstruction during the time period of this report. RESULTS: Eighty-six patients with an average age of 59.4 years presented with massive rotator cuff tears (Cofield >5 cm). Outcome data revealed improvement in VAS (4.0-1.5), and ASES (52-82) scores at 1 year (P = .005). Radiographic analysis showed increase in acromiohumeral interval (mean 7.1 mm preoperatively to mean 9.7 mm at 1 year) (P = .049) and superior capsular distance (mean 52.9 mm preoperatively to mean 46.2 mm at 1 year) (P = .011). Strength improved significantly (forward flexion/abduction/external rotation of 4.8/4.1/7.7 lb preoperatively to 9.8/9.2/12.3 lb at 1 year) as well as range of motion (forward flexion/abduction of 120 degrees /103 degrees preoperatively to 160 degrees /159 degrees at 1 year) (P = .044/P = .007/P = .02). At follow-up, 90% of patients were satisfied. CONCLUSIONS: This analysis reveals that arthroscopic SCR with acellular dermal allograft has been successful in decreasing pain and improving function in this patient subset. Radiographic analysis has also shown a consistent and lasting decrease in superior capsular distance and increase in acromiohumeral interval, indicating maintenance of superior capsular stability.

AB - Clostridium difficile toxin-positive diarrheal stool specimens submitted to eight Canadian hospital laboratories from 2013 to 2015 were cultured. Polymerase chain reaction ribotyping of isolates was performed using an internationally standardized, high-resolution capillary gel-based electrophoresis protocol and antimicrobial susceptibility testing conducted by CLSI-defined agar dilution (M11 A8, 2012). Among the 1310 isolates of C. difficile cultured, 141 different ribotypes were identified; the most common ribotypes were 027 (24.5% of isolates), 014 (7.7%), 020 (6.6%), 106 (6.1%), and 002 (4.6%). Ribotype 027 was the commonest ribotype in all geographic regions of Canada and was more frequently isolated from patients aged >=80 years (40.6%) than younger patients (P<0.00001). Ribotype 027 isolates were frequently moxifloxacin-resistant (92.2% of isolates) and multidrug-resistant (49.5%). Fidaxomicin demonstrated the greatest in vitro potency (lowest MIC90, 0.5 MUg/mL; lowest maximum MIC, 2 MUg/mL) of eight antimicrobial agents tested and was the most active agent against each of the five commonest ribotypes (MIC90, 0.25-1 MUg/mL). PMID- 29456072 TI - Acute illness from Campylobacter jejuni may require high doses while infection occurs at low doses. AB - Data from a set of different studies on the infectivity and pathogenicity of Campylobacter jejuni were analyzed with a multilevel model, allowing for effects of host species (nonhuman primates and humans) and different strains of the pathogen. All challenge studies involved high doses of the pathogen, resulting in all exposed subjects to become infected. In only one study a dose response effect (increasing trend with dose) for infection was observed. High susceptibility to infection with C. jejuni was found in a joint analysis of outbreaks and challenge studies. For that reason four outbreaks, associated with raw milk consumption, were also included in the present study. The high doses used for inoculation did not cause all infected subjects to develop acute enteric symptoms. The observed outcomes are consistent with a dose response effect for acute symptoms among infected subjects: a conditional illness dose response relation. Nonhuman primates and human volunteers did not appear to have different susceptibilities for developing enteric symptoms, but exposure in outbreaks (raw milk) did lead to a higher probability of symptomatic campylobacteriosis.

For colistin, EUCAST breakpoints were applied and testing of isolates with very major (VM) errors was repeated in duplicate by both methods to determine a majority result. Essential agreement (MIC +/- one dilution) of GNX2F with the reference method was 97.1% for polymyxin B and 92.5% for colistin (7 VM errors, 22.6%). After discrepancy testing, there were 28 colistin resistant isolates by BMD and essential agreement was 94.3% with 4 VM errors (14.3%). Colistin and polymyxin B GNX2F results showed acceptable essential agreement with BMD for MICS without interpretation. Colistin VM errors with EUCAST breakpoints were due to MIC variability in the 2 to 4 MUg/mL range that could be addressed by establishing an intermediate category.

AB - A carbohydrate-restricted diet is a widely recommended intervention for non alcoholic fatty liver disease (NAFLD), but a systematic perspective on the multiple benefits of this diet is lacking. Here, we performed a short-term intervention with an isocaloric low-carbohydrate diet with increased protein content in obese subjects with NAFLD and characterized the resulting alterations in metabolism and the gut microbiota using a multi-omics approach. We observed rapid and dramatic reductions of liver fat and other cardiometabolic risk factors paralleled by (1) marked decreases in hepatic de novo lipogenesis; (2) large increases in serum beta-hydroxybutyrate concentrations, reflecting increased mitochondrial beta-oxidation; and (3) rapid increases in folate-producing Streptococcus and serum folate concentrations. Liver transcriptomic analysis on biopsy samples from a second cohort revealed downregulation of the fatty acid synthesis pathway and upregulation of folate-mediated one-carbon metabolism and fatty acid oxidation pathways. Our results highlight the potential of exploring diet-microbiota interactions for treating NAFLD. PMID- 29456074 TI - Histone deacetylases (HDACs) as therapeutic target for depressive disorders. AB - Major depressive disorder (MDD) represents approximately 40% of the disability caused by mental illnesses globally. The poorly understood pathophysiology and limited efficiency of pharmacological treatment (based primarily on the principles of the monoaminergic hypothesis) make depression a serious medical, public and socio-economical problem. An increasing number of studies suggest that epigenetic modifications (alterations in gene expression that are not due to changes in DNA sequence) in certain brain regions and neural circuits represent a key mechanism through which environmental factors interact with individual's genetic constitution to affect risk of mental disorders. Accordingly, chromatin based epigenetic regulation seems to be a promising direction for the development of new, more effective antidepressant drugs. Recently, several inhibitors of histone deacetylases (HDAC) have been extensively studied in the context of antidepressant action. So far, none of them has been used to treat depression in humans due to the low selectivity for specific HDAC isoforms, and consequently, a risk of serious adverse events. In this review, we focus on the HDAC inhibitors (HDACi) with the greatest antidepressant efficacy and their activity in the preclinical studies. Moreover, we discuss their potential therapeutic usefulness in depression and the main limitations. PMID- 29456075 TI - Qualitative Analysis of a Cultural Dexterity Program for Surgeons: Feasible, Impactful, and Necessary. AB - OBJECTIVES: Ineffective cross-cultural communication contributes to adverse outcomes for minority patients. To address this, the authors developed a novel curriculum for surgical residents built on the principle of cultural dexterity, emphasizing adaptability to clinical and sociocultural circumstances to tailor care to the needs of the individual patient. This study's objective was to evaluate the feasibility, acceptability, and perception of this program upon conclusion of its first year. DESIGN, SETTING, AND PARTICIPANTS: The curriculum was implemented at 3 general surgery programs. The flipped classroom model combined independent study via e-learning modules with interactive role-playing sessions. Sessions took place over 1 academic year. Four focus groups were held, each with 6 to 9 participants, to gain feedback on the curriculum. Focus groups were recorded and transcribed, and the data were analyzed using a grounded theory approach. RESULTS: Five major themes emerged: (1) Role modeling from senior colleagues is integral in developing communication/interpersonal skills and attitudes toward cultural dexterity. (2) Cultural dexterity is relevant to the provision of high-quality surgical care. (3) Barriers to providing culturally dexterous care exist at the system level. (4) "Buy-in" at all levels of the institution is necessary to implement the principles of cultural dexterity. (5) The shared experience of discussing the challenges and triumphs of caring for a diverse population was engaging and impactful. CONCLUSION: Early implementation of the curriculum revealed that the tension between surgical residents' desire to improve their cultural dexterity and systemic/practical obstacles can be resolved. Combining surgically relevant didactic materials with experiential learning activities can change the paradigm of cross-cultural training.

PMID- 29456077 TI - Talus Fracture of the Medial Tubercle of the Posterior Process: Interposition of the Flexor Hallucis Longus Tendon. AB - Talus fracture of the medial tubercle of the posterior process is rare. This type of fracture can be easily missed, because it is difficult to identify on plain radiographs of the ankle. Oblique radiographs with external rotation, computed tomography, and magnetic resonance imaging (MRI) of the ankle are useful for making an accurate diagnosis. However, even with an early diagnosis, the treatment guidelines for talus fractures of the posterior medial tubercle have not yet been established. The flexor hallucis longus (FHL) tendon, which passes through the groove between the medial and lateral tubercles of the posterior process of the talus, can interpose between the fracture sites and interrupt fracture reduction. MRI might be the best imaging modality for the identification of the interposed FHL tendon. We report a case in which talus fracture of the posterior medial tubercle was treated by open reduction and internal fixation owing to an interposed FHL tendon that was confirmed by MRI. MRI is the recommended imaging study of choice for talus fractures of the posterior medial tubercle owing to the possibility of an interposed FHL tendon. PMID- 29456078 TI - Transmalleolar Approach for Arthroscopy-Assisted Headless Screw Fixation of an Osteochondral Talar Dome Fracture. AB - Displaced osteochondral fractures of the body of talus quite often require a malleolar osteotomy to gain access to the fracture fragment during internal fixation. We describe a case report in which access to a displaced osteochondral fracture of the lateral talar dome was achieved using an arthroscopy-assisted fibular tunnel approach. This technique resulted in satisfactory fracture healing and a satisfactory clinical outcome.

PMID- 29456079 TI - Phase IV randomized clinical study: Peginterferon alfa-2a with adefovir or entecavir pre-therapy for HBeAg-positive chronic hepatitis B. AB - BACKGROUND: Efficacy of sequential therapy with nucleos(t)ide analogues and interferons versus monotherapy in patients with hepatitis B e antigen (HBeAg) positive chronic hepatitis B (CHB) remains unexplored. We aimed to assess efficacy and safety of sequential therapy with adefovir (ADV) or entecavir (ETV) followed by peginterferon (PEG-IFN) alfa-2a in Taiwanese patients with HBeAg positive. METHODS: This randomized, placebo-controlled, double-blind trial was conducted at nine sites in Taiwan from April 2010 to October 2013. Patients (N = 280) were randomized 1:1:1 to receive placebo, ETV or ADV alone for four weeks, combined with PEG-IFN alfa-2a for two weeks, then PEG-IFN alfa-2a alone for 46 weeks. The primary efficacy end point was HBeAg seroconversion at 48 weeks post treatment. RESULTS: No significant differences were observed among groups for HBeAg seroconversion (PEG-IFN alfa-2a+placebo, 36.3%; PEG-IFN alfa-2a+ETV, 29.5%; and PEG-IFN alfa-2a+ADV, 27.4%), HBeAg loss (37.4%, 32.2%, and 28.6%, respectively) or change in hepatitis B surface antigen (HBsAg) levels from baseline (-0.56 IU/mL, -0.60 IU/mL, and -0.41 IU/mL, respectively). However, hepatitis B virus DNA levels were higher with PEG-IFN alfa-2a+placebo than PEG IFN alfa+ETV at week 64 (p = 0.0412), 76 (p = 0.0311), and 88 (p = 0.0113), and alanine aminotransferase (ALT) normalization rate was higher with PEG-IFN alfa 2a+placebo than PEG-IFN alfa-2a+ADV (p = 0.0283) or PEG-IFN alfa-2a+ETV (p = 0.0369) at week 88. Sub-analysis of results revealed an association between on treatment HBsAg and ALT levels and efficacy 48 weeks post-treatment. Safety was comparable among treatment groups. CONCLUSION: Pre-therapy with ADV or ETV followed by PEG-IFN alfa-2a is not superior to PEG-IFN alfa-2a monotherapy in Taiwanese patients with HBeAg-positive CHB. CLINICAL TRIAL ID: NCT: 00922207. PMID- 29456081 TI - Lysozyme Counteracts beta-Lactam Antibiotics by Promoting the Emergence of L-Form Bacteria. AB - beta-lactam antibiotics inhibit bacterial cell wall assembly and, under classical microbiological culture conditions that are generally hypotonic, induce explosive cell death. Here, we show that under more physiological, osmoprotective conditions, for various Gram-positive bacteria, lysis is delayed or abolished, apparently because inhibition of class A penicillin-binding protein leads to a block in autolytic activity. Although these cells still then die by other mechanisms, exogenous lytic enzymes, such as lysozyme, can rescue viability by enabling the escape of cell wall-deficient "L-form" bacteria. This protective L form conversion was also observed in macrophages and in an animal model, presumably due to the production of host lytic activities, including lysozyme. Our results demonstrate the potential for L-form switching in the host environment and highlight the unexpected effects of innate immune effectors, such as lysozyme, on antibiotic activity. Unlike previously described dormant persisters, L-forms can continue to proliferate in the presence of antibiotic. PMID- 29456082 TI - Identification of piRNA Binding Sites Reveals the Argonaute Regulatory Landscape of the C. elegans Germline. AB - piRNAs (Piwi-interacting small RNAs) engage Piwi Argonautes to silence transposons and promote fertility in animal germlines. Genetic and computational studies have suggested that C. elegans piRNAs tolerate mismatched pairing and in principle could target every transcript. Here we employ in vivo cross-linking to identify transcriptome-wide interactions between piRNAs and target RNAs. We show that piRNAs engage all germline mRNAs and that piRNA binding follows microRNA like pairing rules. Targeting correlates better with binding energy than with piRNA abundance, suggesting that piRNA concentration does not limit targeting. In mRNAs silenced by piRNAs, secondary small RNAs accumulate at the center and ends of piRNA binding sites. In germline-expressed mRNAs, however, targeting by the CSR-1 Argonaute correlates with reduced piRNA binding density and suppression of piRNA-associated secondary small RNAs. Our findings reveal physiologically important and nuanced regulation of individual piRNA targets and provide evidence for a comprehensive post-transcriptional regulatory step in germline gene expression. PMID- 29456083 TI - Placeholder Nucleosomes Underlie Germline-to-Embryo DNA Methylation Reprogramming. AB - The fate and function of epigenetic marks during the germline-to-embryo transition is a key issue in developmental biology, with relevance to stem cell programming and transgenerational inheritance. In zebrafish, DNA methylation patterns are programmed in transcriptionally quiescent cleavage embryos; paternally inherited patterns are maintained, whereas maternal patterns are reprogrammed to match the paternal. Here, we provide the mechanism by demonstrating that "Placeholder" nucleosomes, containing histone H2A variant H2A.Z(FV) and H3K4me1, virtually occupy all regions lacking DNA methylation in both sperm and cleavage embryos and reside at promoters encoding housekeeping and early embryonic transcription factors. Upon genome-wide transcriptional onset, genes with Placeholder become either active (H3K4me3) or silent (H3K4me3/K27me3). Notably, perturbations causing Placeholder loss confer DNA methylation accumulation, whereas acquisition/expansion of Placeholder confers DNA hypomethylation and improper gene activation. Thus, during transcriptionally quiescent gametic and embryonic stages, an H2A.Z(FV)/H3K4me1-containing Placeholder nucleosome deters DNA methylation, poising parental genes for either gene-specific activation or facultative repression. PMID- 29456084 TI - Rescue of Fragile X Syndrome Neurons by DNA Methylation Editing of the FMR1 Gene. AB - Fragile X syndrome (FXS), the most common genetic form of intellectual disability in males, is caused by silencing of the FMR1 gene associated with hypermethylation of the CGG expansion mutation in the 5' UTR of FMR1 in FXS patients. Here, we applied recently developed DNA methylation editing tools to reverse this hypermethylation event. Targeted demethylation of the CGG expansion by dCas9-Tet1/single guide RNA (sgRNA) switched the heterochromatin status of the upstream FMR1 promoter to an active chromatin state, restoring a persistent expression of FMR1 in FXS iPSCs. Neurons derived from methylation-edited FXS iPSCs rescued the electrophysiological abnormalities and restored a wild-type phenotype upon the mutant neurons. FMR1 expression in edited neurons was maintained in vivo after engrafting into the mouse brain. Finally, demethylation of the CGG repeats in post-mitotic FXS neurons also reactivated FMR1. Our data establish that demethylation of the CGG expansion is sufficient for FMR1 reactivation, suggesting potential therapeutic strategies for FXS. PMID- 29456085 TI - What is the Role of Reversal Agents in the Management of Emergency Department Patients with Dabigatran-Associated Hemorrhage? AB - BACKGROUND: In 2010, the U.S. Food and Drug Administration (FDA) approved dabigatran as the first non-warfarin oral anticoagulant for use in the United States. At the time of FDA approval, there was no antidote or effective treatment for dabigatran-induced hemorrhage. In 2015, the FDA approved idarucizumab for the treatment of dabigatran-induced hemorrhage. The purpose of this clinical practice statement is to evaluate the role of select reversal agents in the management of patients with dabigatran-associated bleeding. METHODS: A PubMed literature review was completed to identify studies that investigated the role of reversal agents in the management of emergency department patients with dabigatran-associated hemorrhage. Articles included were those published in the English language between January 2010 and January 2017, enrolled human subjects, and limited to the following types: randomized controlled trials, prospective trials, meta analyses, and retrospective cohort studies. Review articles, case series, and case reports were not included in this review. All selected articles then underwent a structured review by the authors. RESULTS: Six hundred fifty-two articles were identified in the search. After use of predetermined inclusion and exclusion criteria, six articles were selected for structured review. CONCLUSION: The clinical efficacy of activated prothrombin complex concentrates, idarucizumab, and recombinant factor VIIa remains unclear until further research is performed. Activated prothrombin complex concentrates, idarucizumab, and recombinant factor VIIa may be considered in patients with serious bleeding from dabigatran, after careful consideration of possible benefits and risks. PMID- 29456086 TI - Low-Dose Propofol for Pediatric Migraine: A Prospective, Randomized Controlled Trial. AB - BACKGROUND: Migraine headaches are a common reason for pediatric emergency department (ED) visits. Small studies suggest the potential efficacy of sub anesthetic doses of propofol for migraine with a favorable side effect profile and potentially decreased length of stay (LOS). OBJECTIVE: The objective of this study was to compare the efficacy of low-dose propofol (LDP) to standard therapy (ST) in pediatric migraine treatment. METHODS: We conducted a prospective, pragmatic randomized controlled trial from April 2014 through June 2016 in the ED at two pediatric hospitals. Patients aged 7-19 years were eligible if they were diagnosed with migraine by the emergency physician and had a presenting visual analog pain score (VAS) of 6-10. Primary outcome was the percent of pain reduction. Secondary outcomes were ED LOS, 24-h rebound headache, return visits to the ED, and adverse reactions. RESULTS: Seventy-four patients were enrolled, but 8 were excluded, leaving 66 patients in the final analysis (36 ST, 30 LDP). Pain reduction was 59% for ST and 51% for LDP (p = 0.34) with 72.2% vs. 73.3% achieving a VAS <= 4 with initial therapy (p = 0.92). There was a nonsignificant trend toward shorter median LOS from drug administration to final disposition favoring propofol (79 min vs. 111 min; p = 0.09). Rebound headache was significantly more common in the ST vs. LDP group (66.7% vs. 25.0%; p = 0.01). CONCLUSIONS: LDP did not achieve better pain reduction than ST, however, LDP was associated with significantly fewer rebound headaches and a nonsignificant trend toward shorter median LOS from drug administration to disposition. PMID- 29456087 TI - Successful Interprofessional Approach to Development of a Resuscitative Endovascular Balloon Occlusion of the Aorta Program at a Community Trauma Center. AB - BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a relatively innovative procedure designed to control critical non-compressible torso hemorrhage. In the United States, this procedure is currently in active use at only a small number of trauma centers. OBJECTIVE: We describe how we developed our REBOA program at an independent academic-affiliated community trauma center. DISCUSSION: Through a close interprofessional and multidisciplinary collaboration led by emergency physicians and trauma surgeons, we were able to successfully develop our program. CONCLUSIONS: Successful implementation of a REBOA program requires close attention to multimodal training, interprofessional roles, team dynamics, financial considerations, and quality assurance processes to safely deliver this potentially life-saving procedure to our trauma patient population.

AB - INTRODUCTION AND AIMS: The growing elderly population and wide use of capsule endoscopy have led to a higher number of procedures in those patients. The aim of the present study was to assess the usefulness of capsule endoscopy in older patients. MATERIALS AND METHODS: All consecutive patients undergoing capsule endoscopy at our center within the time frame of 2004-2016 were classified as older (>=75 years of age) and younger. Findings and diagnostic yield were comparatively assessed. RESULTS: Of 2311 patients (mean age: 59.5 +/- 19.23 years, 44.48% male), 648 were in the older group and 1663 in the younger group. Gastric transit time was shorter in the older patients (p=0.001), whereas small bowel transit time was shorter in the younger patients (p<0.001). Overall diagnostic yield in the elderly was higher (50.66% vs. 41.19%, p<0.001). Obscure gastrointestinal bleeding was the most frequent indication for capsule endoscopy in the elderly (90.4% vs. 53.77%, p<0.001), achieving a higher diagnostic yield than in the younger population (51.47% vs. 42.76%, p=0.002), whereas Crohn's disease, suspected or known neoplasms/polyps, malabsorption syndrome, and abdominal pain were the indications in the younger patient group. Such indications were rare in the older group. Vascular lesions and active bleeding were more frequently diagnosed in the older patients, whereas ulcers/erosions and mucosal atrophy were more common in the younger patients (p<0.001). CONCLUSIONS: Capsule endoscopy achieved a higher overall diagnostic yield in the elderly patients. Obscure gastrointestinal bleeding indication for capsule endoscopy was much more frequent in the advanced-age group and had a higher diagnostic yield. PMID- 29456091 TI - Frequency of human papillomavirus infection in patients with gastrointestinal cancer. AB - INTRODUCTION AND AIM: Cancer is the result of the interaction of genetic and environmental factors. It has recently been related to viral infections, one of which is human papillomavirus. The aim of the present study was to describe the frequency of human papillomavirus infection in patients with digestive system cancers. MATERIALS AND METHODS: A prospective, multicenter, observational study was conducted on patients with gastrointestinal cancer at 2public healthcare institutes in Veracruz. Two tumor samples were taken, one for histologic study and the other for DNA determination of human papillomavirus and its genotypes. Anthropometric variables, risk factors, sexual habits, tumor location, and histologic type of the cancer were analyzed. Absolute and relative frequencies were determined using the SPSS version 24.0 program. RESULTS: Fifty-three patients were studied. They had gastrointestinal cancer located in: the colon (62.26%), stomach (18.87%), esophagus (7.55%), rectum (7.55%), and small bowel (3.77%). Human papillomavirus was identified in 11.32% of the patients, 66.7% of which corresponded to squamous cell carcinoma and 33.3% to adenocarcinoma. Only genotype 18 was identified. Mean patient age was 61.8+/-15.2 years, 56.60% of the patients were men, and 43.40% were women. A total of 15.8% of the patients had a family history of cancer and 31.6% had a personal history of the disease, 38.6% were tobacco smokers, and 61.4% consumed alcohol. Regarding sex, 5.3% of the patients said they were homosexual, 3.5% were bisexual, 29.8% engaged in oral sex, and 24.6% in anal sex. CONCLUSIONS: Our study showed that human papillomavirus infection was a risk factor for the development of gastrointestinal cancer, especially of squamous cell origin. PMID- 29456093 TI - Validation of the French-Canadian Pelvic Girdle Questionnaire. AB - OBJECTIVE: Pain in the pelvic girdle area is commonly reported during pregnancy and the postpartum period, and its impact on quality of life is considerable. The Pelvic Girdle Questionnaire (PGQ), developed in 2011 in Norway, is the only condition-specific tool assessing pelvic girdle pain-related symptoms and disability. The questionnaire was recently translated and adapted for the French Canadian population. The objective of this study was to assess the measurement properties of the previously translated French-Canadian PGQ. METHODS: Eighty-two women with pelvic girdle pain were included in this validation study. The French Canadian PGQ, pain intensity Numeric Rating Scale, and Oswestry Disability Index were completed by participants at baseline, 48 hours later, and 3 to 6 months later to assess test-retest reliability, construct validity, responsiveness, floor and ceiling effects, and internal consistency. RESULTS: Reliability analyses indicated an intraclass correlation coefficient of 0.841 (95% confidence interval [CI] 0.750-0.901) for the global score. Construct validity analyses indicated a Spearman rank correlation coefficient of 0.696 with the Oswestry Disability Index. Responsiveness analyses identified an effect size of 0.908 (95% CI 0.434-1.644) and an area under the receiver operating characteristics curve of 0.823 (95% CI 0.692-0.953). There was no floor or ceiling effect, and internal consistency analyses indicated a Cronbach alpha of .933 for the activity subscale and .673 for the symptom subscale. CONCLUSION: Overall, the French-Canadian version of the PGQ is reliable, valid, and responsive, suggesting that it can be implemented in both research and clinical settings to assess functional limitations in pregnant and postpartum women. PMID- 29456094 TI - Association Among Opioid Use, Treatment Preferences, and Perceptions of Physician Treatment Recommendations in Patients With Neck and Back Pain. AB - OBJECTIVE: The purpose of this study was to explore the relationship between self reported use of opioids by patients with neck and back pain and their demographics, pain characteristics, treatment preferences, and recollections of their physicians' opinions regarding treatment options. METHODS: We analyzed 2017 Gallup Poll survey data from 1680 US adults who had substantial spine pain in the past year and used logistic regression to explore the aforementioned relationships. RESULTS: Our multiple regression analysis indicated that adults with neck or back pain severe enough to have sought health care within the last year were more likely to have used opioids in the last year if they (in descending order of marginal impact) had pain that had lasted 1 year or less (adjusted odds ratio [OR] = 34.35, 90% confidence interval [CI] 17.56-74.32); concurrently used benzodiazepines (OR = 6.02, 90% CI 2.95-12.33); had Medicaid as an insurance source (OR = 3.29, 90% CI 1.40-7.48); indicated that they preferred to use pain medications prescribed by a doctor to treat physical pain (OR = 3.24, 90% CI 1.88-5.60); or were not college educated (OR = 1.83, 90% CI 1.05-3.25). Compared with patients aged 65 years and older, those aged 18 to 34 years were less likely to have used opioids in the past year (OR = 0.09, 90% CI 0.01-0.40, 0.50 for 95% CI). Respondents' perceptions of medical doctors' positive or negative opinions regarding a variety of neck and back pain treatment options were not significantly associated with opioid use. CONCLUSIONS: Patients with neck and back pain who use opioids differ from those who do not use opioids in that they are more likely to have pain that is of shorter duration, to use benzodiazepines, to have Medicaid as an insurance source, and to prefer to use pain medications. Those characteristics should be considered when developing opioid use prevention strategies. PMID- 29456095 TI - Comparison of Median Nerve Mechanosensitivity and Pressure Pain Threshold in Patients With Nonspecific Neck Pain and Asymptomatic Individuals. AB - OBJECTIVE: The purpose of this study was to investigate the presence of median nerve mechanosensitivity by comparing median nerve neurodynamic test results of patients with nonspecific neck pain (NNP) and asymptomatic individuals. METHODS: A total of 40 patients (30 women, 10 men) with NNP between the ages of 21 and 62 years (39.53 +/- 10.18 years) and 38 asymptomatic individuals (23 women, 15 men) between the ages of 18 and 60 years (37.13 +/- 9.64 years) participated in the study. Pressure pain threshold was assessed with digital pressure algometer, cervical joint range of motion was assessed with a universal goniometer, and median nerve mechanosensitivity was assessed with Upper Limb Neurodynamic Test 1 (ULNT1). The test step where the first sensory response was given, the location and character of the sensory response, and the final elbow extension angle were recorded during ULNT1. RESULTS: Patients with NNP had significantly decreased pressure pain threshold (P < .001), decreased range of motion of cervical flexion (P < .001), and decreased cervical lateral flexion (P = .001) compared with asymptomatic individuals, whereas no change was identified in range of motion of rotation (P = .100). In ULNT1, 45% of patients with NNP reported pain and 40% of them reported stretch. A total of 65% of asymptomatic individuals reported stretch, and 13% of them reported pain. It was identified in ULNT1 that final elbow extension angle was lower in the NNP group compared with asymptomatic individuals (P = .008). CONCLUSION: Median nerve mechanosensitivity increased, pressure pain threshold decreased, and active neck motion was limited in individuals with NNP compared with asymptomatic individuals. PMID- 29456096 TI - Cholescintigraphic patterns in a IBS patient with postprandial diarrhea. PMID- 29456097 TI - The timing of early therapeutic strategies has a significant impact on Crohn's disease prognosis. AB - BACKGROUND: Abdominal surgery and immunosuppressive pharmacological treatments are two different therapeutic options used to manage Crohn disease. This study aimed to determine whether the timing of these interventions had an impact on patients' prognosis. METHOD: This manuscript entails a retrospective analysis of a multicentric cohort involving 498 CD patients that had bowel surgery after diagnosis and prior to immunosuppression treatments. Two endpoints were considered: the occurrence of disabling disease and the need to undergo further bowel surgeries. RESULTS: Disabling disease affected 71% of all patients, whereas 39% needed reoperation. The odds ratios (OR) of being affected by disabling disease were higher when patients had upper tract involvement [3.412 [1.285 9.061]], perianal disease (2.270 [1.239-4.157]) and a longer time elapsed from diagnosis to first surgery (13-36 months: 2.576 [1.207-5.500]). On the other hand, the need to undergo further surgical interventions was significantly increased in smoking patients (2.294 [1.187-4.432]), but decreased in patients who started pharmacological therapy not later than six months after the first surgery (0.256 [0.093-0.704]). CONCLUSIONS: Our results suggest that the timing of therapeutic strategies does affects the CD outcomes: whereas an early surgery had a preventive effect on the occurrence of disabling events, the introduction of medication in the first semester after surgery had a preventive effect on the need for reoperation. PMID- 29456098 TI - ArF excimer laser debrides burns without destruction of viable tissue: A pilot study. AB - INTRODUCTION: Recent evidence indicates that early removal of eschar by tangential debridement can promote healing. Laser debridement can be used for debridement of areas that prove challenging for debridement using tangential excision. In particular, irradiation with an ArF excimer laser ablates desiccated eschar and is self-terminating, preserving hydrated or viable tissue. METHODS: Thermal burns were created on the flanks of two outbred, female Yorkshire pigs using aluminum bars heated to 70 degrees C and applied for different lengths of time. Three days after injury, burns were debrided using an ArF excimer laser (193nm). Tissue was harvested immediately after debridement and 7days after debridement (10days after burn). RESULTS: Data from a pilot study demonstrates that ArF excimer laser irradiation removes burn eschar and promotes healing at 10days after burn. ArF excimer laser debridement is self-terminating and preserves underlying and adjacent perfused tissue. Potentially, this modality would be ideal for the complex curvilinear structures of the body. PMID- 29456099 TI - Time to start putting down the knife: A systematic review of burns excision tools of randomised and non-randomised trials. AB - AIMS: Dermal preservation during acute burn excision is key to obtaining superior healing/scar outcomes, however, determining the most appropriate excision tool is an ongoing challenge. Novel tool development means the knife is no longer our only option, yet for the majority it remains the gold standard. This systematic review aims to evaluate evidence for burns excision approaches (knife/hydrosurgery/enzymatic). METHODS: CENTRAL, EMBASE, MEDLINE (1946-2017) were searched with MeSH terms: 'debridement', 'burns', 'sharp', 'enzymatic', 'hydrosurgery'. Relevant randomised control trials (RCTs)/non-randomised controlled case series/trials were extracted/analysed. In vitro/burn non-specific studies were excluded. Main methodological parameters were intervention/excision efficacy. RESULTS: Eighteen articles met inclusion criteria (n=7148): three were RCTs, involving comparator enzymatic (NexoBridTM (EDNX)) or hydrosurgical (VersajetTM) excision to surgical Standard of Care. Both showed statistically significant decreased need for excisional excision and auto-grafting by viable tissue preservation allowing spontaneous healing by epithelialisation. CONCLUSION: Level 1 Evidence comparing excision modalities for acute burns is sparse. Although early excision with a knife is still often considered best practice, there is no tool choice consensus or robust comparison with alternate, possibly superior, tools. EDNX or VersajetTM should be considered alternatively. Further RCTs are indicated, with regards final scar outcomes and to allow consensus within current evidence. PMID- 29456101 TI - Ligand-based modeling of Akt3 lead to potent dual Akt1/Akt3 inhibitor. AB - Akt1 and Akt3 are important serine/threonine-specific protein kinases involved in G2 phase required by cancer cells to maintain cell cycle and to prevent cell death. Accordingly, inhibitors of these kinases should have potent anti-cancer properties. This prompted us to use pharmacophore/QSAR modeling to identify optimal binding models and physicochemical descriptors that explain bioactivity variation within a set of 74 diverse Akt3 inhibitors. Two successful orthogonal pharmacophores were identified and further validated using receiver operating characteristic (ROC) curve analyses. The pharmacophoric models and associated QSAR equation were applied to screen the national cancer institute (NCI) list of compounds for new Akt3 inhibitors. Six hits showed significant experimental anti Akt3 IC50 values, out of which one compound exhibited dual low micromolar anti Akt1 and anti-Akt3 inhibitory profiles. PMID- 29456102 TI - The prognostic capacity of transvaginal hydrolaparoscopy to predict non-IVF conception. AB - Transvaginal hydrolaparoscopy (THL) is performed to investigate tubal pathology in subfertile women. This retrospective multicentre cohort study investigated the results of THL and subsequent pregnancy rates. Between 2000 and 2011, 1033 subfertile women participated in the study. The primary outcome measure was intrauterine pregnancy, either after natural conception or after treatment with intrauterine insemination or ovulation induction. Cumulative intrauterine pregnancy rates were calculated using Kaplan-Meier analysis and fecundity rate ratios (FRR) were established. THL showed bilateral patent tubes in 83%, one sided tubal occlusion in 12.4% and bilateral tubal occlusion in 4.6% of women. Cumulative intrauterine pregnancy rates after 36 months were 52% for women with bilateral patent tubes, 44% for one-sided tubal occlusion (FRR 1.04; 95% confidence interval [CI], 0.78 to 1.39) and 7% for bilateral tubal occlusion (FRR 0.13; 95% CI, 0.04 to 0.43). Endometriosis was diagnosed in 6.4%, and adhesions in 9.1%, while 3.9% of women had both. Corresponding FRR were 0.73 (95% CI, 0.49 to 1.09), 0.68 (95% CI, 0.46 to 1.02) and 0.42 (95% CI, 0.20 to 0.84). In conclusion, women with bilateral tubal occlusion or a combination of endometriosis and adhesions found on THL significantly reduced chances of natural conception. PMID- 29456100 TI - The Coding Regions of Germline mRNAs Confer Sensitivity to Argonaute Regulation in C. elegans. AB - Protein-coding genes undergo a wide array of regulatory interactions with factors that engage non-coding regions. Open reading frames (ORFs), in contrast, are thought to be constrained by coding function, precluding a major role in gene regulation. Here, we explore Piwi-interacting (pi)RNA-mediated transgene silencing in C. elegans and show that marked differences in the sensitivity to piRNA silencing map to the endogenous sequences within transgene ORFs. Artificially increasing piRNA targeting within the ORF of a resistant transgene can lead to a partial yet stable reduction in expression, revealing that piRNAs not only silence but can also "tune" gene expression. Our findings support a model that involves a temporal element to mRNA regulation by germline Argonautes, likely prior to translation, and suggest that piRNAs afford incremental control of germline mRNA expression by targeting the body of the mRNA, including the coding region. PMID- 29456103 TI - Straddling care and education: Developing interprofessional collaboration through a hotspotting service learning project. AB - Interprofessional (IP) team work has been shown to decrease burnout and improve care and decrease costs. However, institutional barriers have challenged adoption in practice and education. Faculty and students are turning to IP service learning projects to help students gain experience and provide needed services. This paper highlights a "hotspotting" program where students from different health professions work collaboratively to improve high utilizing patients' health. Benefits, challenges and preliminary results including cost savings and student efficacy are shared. Institutions should surmount barriers that make hotspotting service-learning challenging as IP team-based experiences prepare students for the workplace and can help mitigate burnout. PMID- 29456104 TI - Methodological considerations for developmental longitudinal fMRI research. AB - There has been a large spike in longitudinal fMRI studies in recent years, and so it is essential that researchers carefully assess the limitations and challenges afforded by longitudinal designs. In this article, we provide an overview of important considerations for longitudinal fMRI research in developmental samples, including task design, sampling strategies, and group-level analyses. We first discuss considerations for task designs, weighing the pros and cons of many commonly used tasks, as well as outlining how the tasks may be impacted by repeated exposure. Secondly, we review the types of group-level analyses that can be conducted on longitudinal fMRI data, analyses which must account for repeated measures. Finally, we review and critique recent longitudinal studies that have emerged in the past few years. PMID- 29456105 TI - Marine bis-gamma-pyrone polypropionates of onchidione family and their effects on the XBP1 gene expression. AB - Two additional new members of the onchidione family, 16-epi-onchidione (1) and 4 epi-onchidione (2), co-occurring with six previously reported bis-gamma-pyrone polypropionates including onchidione (3), were isolated from the marine pulmonate Onchidium sp. Their structures were determined by extensive spectroscopic analysis and by comparison with 3 and onchidione-related derivatives. The absolute configuration of 1 was established by X-ray diffraction analysis employing graphite monochromated Cu Kalpha radiation (lambda = 0.71073 A) with small Flack parameter 0.08. In addition, the absolute stereochemistry of previously reported onchidionol (6) was confirmed by the X-ray diffraction analysis. Some of the isolated compounds showed significant activation effects on the splicing of XBP1 mRNA as ER stress modulators to inhibit the growth of tumors. PMID- 29456106 TI - Design, synthesis and anticancer activities evaluation of novel 5H dibenzo[b,e]azepine-6,11-dione derivatives containing 1,3,4-oxadiazole units. AB - Rucaparib and PJ34 were used as the structural model for the design of novel 5H dibenzo[b,e]azepine-6,11-dione derivatives containing 1,3,4-oxadiazole units. And target compounds were successfully synthesized through a 3-step synthetic strategy. All target compounds were screened for their anti-proliferative effects against OVCAR-3 cell line. Preliminary biological study of these compounds provided potent compounds d21 and d22 with better activities than Rucaparib. PMID- 29456107 TI - Design, synthesis, and discovery of 5-((1,3-diphenyl-1H-pyrazol-4 yl)methylene)pyrimidine-2,4,6(1H,3H,5H)-triones and related derivatives as novel inhibitors of mPGES-1. AB - Human mPGES-1 has emerged as a promising target in exploring a next generation of anti-inflammatory drugs, as selective mPGES-1 inhibitors are expected to discriminatively suppress the production of induced PGE2 without blocking the normal biosynthesis of other prostanoids including homeostatic PGE2. Therefore, this therapeutic approach is believed to reduce the adverse effects associated with the application of traditional non-steroidal anti-inflammatory drugs (tNSAIDs) and selective COX-2 inhibitors (coxibs). Identified from structure based virtue screening, the compound with (Z)-5-benzylidene-2-iminothiazolidin-4 one scaffold was used as lead in rational design of novel inhibitors. Besides, we further designed, synthesized, and evaluated 5-((1,3-diphenyl-1H-pyrazol-4 yl)methylene)pyrimidine-2,4,6(1H,3H,5H)-triones and structurally related derivatives for their in vitro inhibitory activities. According to in vitro activity assays, a number of these compounds were capable of inhibiting human mPGES-1, with the desirable selectivity for mPGES-1 over COX isozymes.

PMID- 29456109 TI - Synthetic strigolactone analogues reveal anti-cancer activities on hepatocellular carcinoma cells. AB - Hepatocellular carcinoma (HCC) remains one of the leading causes of death worldwide. The complex etiology is attributed to many factors like heredity, cirrhosis, hepatitis infections or the dysregulation of the different molecular pathways. Nevertheless, the current treatment regimens have either severe side effects or tumors gradually acquire resistance upon prolonged use. Thus, developing a new selective treatment for HCC is the need of the hour. Many anticancer agents derived from plants have been evaluated for their cytotoxicity towards many human cancer cell lines. Strigolactones (SLs)-a newly discovered class of phytohormones, play a crucial role in the development of plant-root and shoot. Recently, many synthetic analogues of SLs have demonstrated pro-apoptotic effects on different cancer cell lines like prostate, breast, colon and lung. In this study, we tested synthetic SLs analogues on HCC cell line-HepG2 and evaluated their capability to induce cell proliferation inhibition and apoptosis. Primary WST-1 assays, followed by annexin-V/7AAD staining, demonstrated the anti proliferative effects. The SLs analogues TIT3 and TIT7 were found to significantly reduce HepG2 cell viability in a dose- and time-dependent manner and induce apoptosis. Interestingly, though TIT3 and TIT7 strongly affected cancer cell proliferation, both compounds showed moderate anti-proliferative effect on normal cells. Further, migration of cancer cells was suppressed upon treatment with TIT3 and TIT7 in a wound healing assay. In summary, these findings suggest that two SLs analogues TIT3 and TIT7 exert selective inhibitory effects on cancer cells most likely through targeting microtubules. SLs analogues could be used in future as potential anti-cancer candidates in chemotherapy. PMID- 29456110 TI - Synthesis, spectroscopic studies and biological evaluation of acridine derivatives: The role of aggregation on the photodynamic efficiency. AB - Two new photoactive compounds (1 and 2) derived from the 9-amidoacridine chromophore have been synthesized and fully characterized. Their abilities to produce singlet oxygen upon irradiation have been compared. The synthesized compounds show very different self-aggregating properties since only 1 present a strong tendency to aggregate in water. Biological assays were conducted with two cell types: hepatoma cells (Hep3B) and human umbilical vein endothelial cells (HUVEC). Photodynamic therapy (PDT) studies carried out with Hep3B cells showed that non-aggregating compound 2 showed photoxicity, ascribed to the production of singlet oxygen, being aggregating compound 1 photochemically inactive. On the other hand suspensions of 1, characterized as nano-sized aggregates, have notable antiproliferative activity towards this cell line in the dark. PMID- 29456111 TI - Methyllucidone inhibits STAT3 activity by regulating the expression of the protein tyrosine phosphatase MEG2 in DU145 prostate carcinoma cells. AB - During the search for signal transducer and activator of transcription 3 (STAT3) inhibitors from natural products, methyllucidone, isolated from Lindera species (Lauraceae), was identified as a STAT3 inhibitor. Methyllucidone inhibited STAT3 phosphorylation at tyrosine 705 in a dose- and time dependent manner in DU145 prostate cancer cells and suppressed IL-6-induced STAT3 phosphorylation at Tyr 705 in LNCaP cells. Methyllucidone decreased the expression levels of STAT3 target genes, such as cyclin D1, cyclin A, Bcl-2, Mcl-1, and survivin. Methyllucidone inhibited DU145 cell growth and induced apoptosis by arresting the cell cycle at G1 phase. Notably, knockdown of the MEG2 gene by small interfering RNA suppressed the ability of methyllucidone to inhibit STAT3 activation. Methyllucidone regulates STAT3 activity by modulating MEG2 expression, and our results suggest that this compound is a novel inhibitor of the STAT3 pathway and may be a useful lead molecule for the development of a therapeutic STAT3 inhibitor. PMID- 29456112 TI - Discovery of DSP-1053, a novel benzylpiperidine derivative with potent serotonin transporter inhibitory activity and partial 5-HT1A receptor agonistic activity. AB - We have previously shown that SMP-304, a serotonin uptake inhibitor with weak 5 HT1A partial agonistic activity, may act under high serotonin levels as a 5-HT1A antagonist that improves the onset of paroxetine in the rat swimming test. However, SMP-304 is mostly metabolized by CYP2D6, indicating limited efficacy among individuals and increased side effects. To reduce CYP2D6 metabolic contribution and enhance SERT/5-HT1A binding affinity, we carried out a series of substitutions at the bromine atom in the left part of the benzene ring of SMP-304 and replaced the right part of SMP-304 with a chroman-4-one. This optimization work led to the identification of the antidepressant candidate DSP-1053 as a potent SERT inhibitor with partial 5-HT1A receptor agonistic activity. DSP-1053 showed low CYP2D6 metabolic contribution and a robust increase in serotonin levels in the rat frontal cortex. PMID- 29456113 TI - Design, synthesis, and evaluation of the antiproliferative activity of hydantoin derived antiandrogen-genistein conjugates. AB - Androgen receptor (AR) signaling is vital to the viability of all forms of prostate cancer (PCa). With the goal of investigating the effect of simultaneous inhibition and depletion of AR on viability of PCa cells, we designed, synthesized and characterized the bioactivities of bifunctional agents which incorporate the independent cancer killing properties of an antiandrogen and genistein, and the AR downregulation effect of genistein within a single molecular template. We observed that a representative conjugate, 9b, is much more cytotoxic to both LNCaP and DU145 cells relative to the antiandrogen and genistein building blocks as single agents or their combination. Moreover, conjugate 9b more effectively down regulates cellular AR protein levels relative to genistein and induces S phase cell cycle arrest. The promising bioactivities of these conjugates warrant further investigation. PMID- 29456115 TI - Reply to Letter to the Editor. PMID- 29456114 TI - Detection and genetic characterization of Mamastrovirus 5 from Brazilian dogs. AB - Mamastrovirus 5 (MAstV5), belonging to the Astroviridae (AstV) family, previously known as canine astrovirus or astrovirus-like particles, has been reported in several countries to be associated with viral enteric disease in dogs since the 1980s. Astroviruses have been detected in fecal samples from a wide variety of mammals and birds that are associated with gastroenteritis and extra enteric manifestations. In the present study, RT-PCR was used to investigate the presence of MAstV5 in 269 dog fecal samples. MAstV5 was detected in 26% (71/269) of the samples. Interestingly, all MAstV5-positive samples derived from dogs displaying clinical signs suggestive of gastroenteritis, other enteric viruses were simultaneously detected (canine parvovirus, canine distemper virus, canine coronavirus, canine adenovirus and canine rotavirus). Based on genomic sequence analysis of MAstV5 a novel classification of the species into four genotypes, MAstV5a-MAstV5d, is proposed. Phylogenetic analyses based on the ORF2 amino acid sequences, samples described herein grouped into the putative genotype 'a' closed related with Chinese samples. Other studies are required to attempt the clinical and antigenic implications of these astrovirus genotypes in dogs. PMID- 29456116 TI - Influence of topical steroids on intraocular pressure in patients with atopic dermatitis. AB - BACKGROUND: Topical corticosteroids (TCS) can induce adverse effects, such as skin atrophy. Although TCS can cause increases in intraocular pressure (IOP), the effects of daily TCS use on IOP have not been fully elucidated. We evaluated the clinical doses of TCS and the change in the IOP during the daily treatment of atopic dermatitis (AD). METHODS: We collected clinical data on a total of 65 patients who were diagnosed with AD and underwent 2 or more IOP measurements at our hospital. RESULTS: Mean monthly facial steroid volumes of <=11.8 g and <=15.0 g of TCS were applied to 90% of the patients aged 2-12 years and those aged >=13 years, respectively. During the treatment, there were no TCS-related increases in IOP in any patient. CONCLUSIONS: Our study suggests that TCS might not cause increases in IOP at the abovementioned doses. However, the IOP of steroid responders is known to be highly responsive to steroids. Therefore, patients who have steroids applied to their eyelids had better undergo regular IOP measurements at ophthalmological clinics. PMID- 29456117 TI - Extraordinary daytime only urinary frequency in childhood: Prevalence, diagnosis, and management. AB - INTRODUCTION: Since standardization of the ICCS terminology, only two small case series of children with extraordinary daytime only urinary frequency (EDOUF) have been published. The aims of the present study were i) to describe a large cohort of children affected by EDOUF, to evaluate its rate among the main micturition pediatric disturbances, and to determine if there is different EDOUF onset among seasons; ii) to investigate possible associations with urodynamic abnormalities by non-invasive techniques; iii) to evaluate whether postponing micturition exercise (PME) can objectively verify the anamnestic data hinting at the EDOUF diagnosis; and iv) to determine the effect of postponing micturition at home. MATERIAL AND METHODS: We reviewed the records of all patients with EDOUF, nocturnal enuresis, and/or overactive bladder firstly examined from March 2012 to February 2016. We evaluated post-void residual and bladder wall thickness by urinary ultrasound and uroflowmetry and recorded the season in which the EDOUF started. Through the PME, the EDOUF diagnosis was confirmed if patients were able to postpone micturition reaching at least 80% of the expected bladder capacity without showing urinary incontinence. At home, we recommended postponing micturition for a maximum of 3 h if EDOUF affected the normal daily activities of both children and parents. We set a telephone interview for 3 months later. RESULTS: The clinical characteristics of the EDOUF population are shown in the Table. The EDOUF rate was 12.1%. The rate of EDOUF onset was significantly lower during the summer than in other seasons (p = 0.02) and the OR for onset of EDOUF in the summer - compared with the other seasons - was 0.37 (95% CI 0.18-0.74; p = 0.005). Eighty-five (80.2%) patients reported an intermittent trend of the EDOUF with variable periods of improvement and worsening. All the EDOUF patients had normal uroflowmetry, 1/106 had post-micturition bladder wall thickness >5 mm and one post-void residual. At the PME, 106 out of 106 (100%) patients with EDOUF were able to reach at least 80% of the EBC without showing urinary incontinence or urgency incontinence. After 3 months, in 98.1% of the patients the symptoms had disappeared or improved. DISCUSSION AND CONCLUSIONS: Childhood EDOUF is rather common and is generally associated with normal non-invasive urodynamic patterns. The PME allows verification of anamnestic data of EDOUF. The sole recommendation to postpone micturition for a maximum of 3 h or until the micturition postponement became stressful could be considered as a possible approach. PMID- 29456118 TI - Simulation in paediatric urology and surgery, part 2: An overview of simulation modalities and their applications. AB - Surgical training has changed radically in the last few decades. The traditional Halstedian model of time-bound apprenticeship has been replaced with competency based training. In our previous article, we presented an overview of learning theory relevant to clinical teaching; a summary for the busy paediatric surgeon and urologist. We introduced the concepts underpinning current changes in surgical education and training. In this next article, we give an overview of the various modalities of surgical simulation, the educational principles that underlie them, and potential applications in clinical practice. These modalities include; open surgical models and trainers, laparoscopic bench trainers, virtual reality trainers, simulated patients and role-play, hybrid simulation, scenario based simulation, distributed simulation, virtual reality, and online simulation. Specific examples of technology that may be used for these modalities are included but this is not a comprehensive review of all available products. PMID- 29456119 TI - Prevalence of UTI among Iranian infants with prolonged jaundice, and its main causes: A systematic review and meta-analysis study. AB - INTRODUCTION: An extremely variable and high prevalence of urinary tract infection (UTI) in infants with prolonged jaundice has been reported in Iran. However, there is no research from the area that has attempted to estimate pooled prevalence of UTI from considerably diverse evidence. Therefore, this systematic review and meta-analysis study aimed to estimate the prevalence of UTI in infants with prolonged jaundice who were admitted into clinics or hospitals in Iran. METHODS: A systematic review and meta-analysis was conducted of published articles on UTI prevalence in infants with prolonged jaundice in Iran. Electronic databases were searched, including Web of Sciences, PubMed/Medline, Scopus, Iranian Scientific Information Database (SID) and Iranmedex, for both English and Persian language articles published between January, 2000 and March, 2017. All possible combinations of the following keywords were used: jaundice, icterus, hyperbilirubinemia during infancy, infection and neonatal. Nine studies that reported prevalence of UTI in infants with prolonged jaundice were included. The overall prevalence of UTI was estimated using random-effects meta-analysis models. RESULTS: A total of 1750 infants were pooled to estimate the overall prevalence of UTI in infants with prolonged jaundice. The prevalence reported by the studies included in this literature review was extremely variable and ranged 0.6-53.9%. The overall prevalence was 11% (95% Confidence Interval (CI): 5.0 18.0), and Escherichia coli was found to be the main cause of UTI. CONCLUSION: The overall prevalence of UTI was 11%, and E. coli was the main cause of UTI in infants with prolonged jaundice. Screening of UTI should be considered for infants with prolonged jaundice. PMID- 29456120 TI - Bladder debris on ultrasound as a predictor for positive urine culture in a pediatric population. AB - INTRODUCTION: Debris within the bladder is commonly seen on ultrasound. The etiology of bladder debris is varied and the likelihood that urinary debris represents positive urine culture is under investigation. We hypothesize that bladder debris will increase the likelihood that a urine culture is positive compared to those without bladder debris. METHODS: We performed a retrospective review on children aged 0-17 years who had a voiding cystourethrogram with a catheterized urinalysis or urine culture, and who also had a renal and bladder ultrasound up to 1 week prior, the day of, or up to 2 days after their urine studies. Presence of bladder debris and debris severity was recorded. Positive urine culture was defined as a single bacterial strain >=50,000 cfu/mL. Demographic information, including findings of reflux and hydronephrosis were compared. Sensitivity, specificity, and risk ratios were calculated for predicting positive urine culture in patients with urinary debris on ultrasound. RESULTS: A total of 445 patients met inclusion criteria between January and December 2014. The positive urine culture rate was 20%, and the rate of bladder debris was 22%. The mean age for those with and without bladder debris was 6.6 and 5.5 years, respectively (p = 0.02). 23% of girls had bladder debris, compared to 12% of boys (p = 0.04, see results table). The sensitivity and specificity for bladder debris in detecting positive urine cultures was 52% and 86%, respectively. Forty-seven percent of those with bladder debris had positive cultures, compared with 12% of those without debris (p < 0.01). The relative risk of positive urine culture if debris is present is 3.90 (95% CI 2.73-5.55). Hydronephrosis or vesicoureteral reflux did not affect the relationship between bladder debris and positive urine cultures. CONCLUSIONS: Nearly half of pediatric patients undergoing urological evaluation found to have bladder debris on ultrasound will have a positive urine culture. Debris is noted more commonly in girls and at a slightly higher age. The presence of debris is associated with a fourfold increase in detecting a positive urine culture, regardless of debris severity, hydronephrosis, or vesicoureteral reflux. Given this, it is of value to routinely document and look for the presence of any amount of bladder debris seen on ultrasound, as this finding can be used to augment clinical decision-making and warrants strong consideration for obtaining urine culture. PMID- 29456121 TI - Establishment of colonic dialysis model in uremic rats by right nephrectomy and left partial nephrectomy. AB - BACKGROUND: Conventional treatments for patients suffering with end-stage renal disease (ESRD) has several disadvantages, highlighting the importance of other reproducible modalities such as colonic dialysis (CD). OBJECTIVES: The aim was to establish a CD model in uremic rats and evaluate the effect of two different peritoneal dialysis (PD) solutions. METHODS: Thirty-two male Wistar rats were randomly divided into four groups. After right nephrectomy and left partial nephrectomy, a Malone antegrade continence enema (MACE) stoma was created. Seven days after the procedure, blood sampling was performed. In group I (N = 8) no postoperative intervention was performed. In group II (N = 8), CD was started through the MACE stoma by a low osmolar PD solution. Rats of group III (N = 8) underwent the same procedure with a high osmolar PD solution. Rats of group IV (N = 8) underwent CD without nephrectomy in order to evaluate the feasibility of this technique. Mannitol and activated charcoal were also added to both PD solutions. Weekly blood sampling was performed in order to evaluate the plasma creatinine and blood urea nitrogen (BUN) level. RESULTS: In rats of the control group, the respective mean +/- SD creatinine level was 1.5 +/- 0.04 mg/dL, 7 days after the surgical procedure, but a lower creatinine level was found in groups II and III (0.8 +/- 0.02 and 0.5 +/- 0.03, respectively). Despite the fact that the creatinine level was in steady low states after regular CD in group II (1 +/- 0.05) and group III (0.6 +/- 0.02), it remained at higher levels in the control group (1.7 +/- 0.08) 2 weeks postoperatively. Rats of group I did not survive until the third postoperative week, while the creatinine level was still lower in group III than in group II (0.6 +/- 0.02 vs. 1.1 +/- 0.03). Similar results were obtained for the BUN level at these timepoints. The mean +/- SD survival period was 11 +/- 2, 20 +/- 3, and 33 +/- 2 days in the animals of groups I, II, and III, respectively. DISCUSSION: To the best of our knowledge, this is the first study of CD establishment in a rat model. Unfortunately, the amount of protein loss, elevation of blood glucose levels, and electrolyte disturbance were not evaluated in the current study because of the limited amount of blood samples. Disturbance of these factors might be a cause of mortality in experimental groups undergoing CD while a significant decrease in BUN and creatinine levels was obtained. CONCLUSION: CD with an efficient PD solution through a MACE stoma may be a valuable option when conventional methods are not available. PMID- 29456122 TI - Blood perfusion in left inferior and middle frontal gyrus predicts communication skills in schizophrenia. AB - Schizophrenia is one of the most debilitating mental disorders, severely affecting patients' community functioning. Functional capacity (FC) describes the skills necessary for successful functional outcome (FO), such as financial knowledge or communication skills. We investigated whether resting-state cerebral blood flow (rCBF) measured at baseline with arterial spin labeling (ASL) would predict FC or FO at a 6-months follow-up in 27 schizophrenia patients. A negative linear association was noted between FC and rCBF in the left inferior and middle frontal gyrus, areas involved in language processing, suggesting a potential relationship between cerebral perfusion and prospective FC in schizophrenia. PMID- 29456123 TI - Activated carbon enhanced anaerobic digestion of food waste - Laboratory-scale and Pilot-scale operation. AB - Effects of activated carbon (AC) supplementation on anaerobic digestion (AD) of food waste were elucidated in lab- and pilot-scales. Lab-scale AD was performed in 1 L and 8 L digesters, while pilot-scale AD was conducted in a 1000 L digester. Based on the optimal dose of 15 g AC per working volume derived from the 1 L digester, for the same AC dosage in the 8 L digester, an improved operation stability coupled with a higher methane yield was achieved even when digesters without AC supplementation failed after 59 days due to accumulation of substantial organic intermediates. At the same time, color removal from the liquid phase of the digestate was dramatically enhanced and the particle size of the digestate solids was increased by 53% through AC supplementation after running for 59 days. Pyrosequencing of 16S rRNA gene showed the abundance of predominant phyla Firmicutes, Elusimicrobia and Proteobacteria selectively enhanced by 1.7-fold, 2.9-fold and 2.1-fold, respectively. Pilot-scale digester without AC gave an average methane yield of 0.466 L?(gVS)-1?d-1 at a composition of 53-61% v/v methane. With AC augmentation, an increase of 41% in methane yield was achieved in the 1000 L digester under optimal organic loading rate (1.6 g VSFW.L-1.d-1). PMID- 29456125 TI - Development and Validation of a Tool to Measure Dietitians' Self-Efficacy with Using Mobile Health Apps in Dietetic Practice. AB - OBJECTIVE: To develop and validate a tool for assessing dietitians' self-efficacy with using mobile health (mHealth) apps in dietetic practice. DESIGN AND PARTICIPANTS: A tool for measuring mHealth app self-efficacy among dietitians was constructed based on a literature review, consultation with experts, and Bandura's self-efficacy scales development guide. Senior dietetic students and new graduate dietitians in Australia (n = 100) tested the tool. OUTCOME MEASURES AND ANALYSIS: Validation of the tool was conducted using factor analysis. Reliability testing was undertaken to examine internal consistency and repeatability. RESULTS: Construct validity was demonstrated through extraction of 4 factors with significant loadings accounting for 68% of variance: efficiency and effectiveness of nutrition care, training and support, integration into dietetic work systems, and familiarity with apps. Internal consistency reliability overall was 0.90; 3 of 4 constructs had Cronbach alpha > .70. Weighted kappas for test-retest reliability indicated moderate to substantial agreement (0.43-0.76). CONCLUSIONS AND IMPLICATIONS: This tool will be useful to researchers and dietetic associations interested in measuring dietitians' levels of mHealth app self-efficacy, developing interventions to enhance self-efficacy, and/or evaluating changes in self-efficacy after professional training. Testing of the tool in a more diverse sample of dietitians and among other health professional groups could enhance the applicability of the tool. PMID- 29456124 TI - A multicenter study of total pancreatectomy with islet autotransplantation (TPIAT): POST (Prospective Observational Study of TPIAT). AB - BACKGROUND/OBJECTIVES: Total pancreatectomy with islet autotransplantation (TPIAT) is considered for managing chronic pancreatitis in selected patients when medical and endoscopic interventions have not provided adequate relief from debilitating pain. Although more centers are performing TPIAT, we lack large, multi-center studies to guide decisions about selecting candidates for and timing of TPIAT. METHODS: Multiple centers across the United States (9 to date) performing TPIAT are prospectively enrolling patients undergoing TPIAT for chronic pancreatitis into the Prospective Observational Study of TPIAT (POST), a NIDDK funded study with a goal of accruing 450 TPIAT recipients. Baseline data include participant phenotype, pancreatitis history, and medical/psychological comorbidities from medical records, participant interview, and participant self report (Medical Outcomes Survey Short Form-12, EQ-5D, andPROMIS inventories for pain interference, depression, and anxiety). Outcome measures are collected to at least 1 year after TPIAT, including the same participant questionnaires, visual analog pain scale, pain interference scores, opioid requirements, insulin requirements, islet graft function, and hemoglobin A1c. Health resource utilization data are collected for a cost-effectiveness analysis. Biorepository specimens including urine, serum/plasma, genetic material (saliva and blood), and pancreas tissue are collected for future study. CONCLUSIONS: This ongoing multicenter research study will enroll and follow TPIAT recipients, aiming to evaluate patient selection and timing for TPIAT to optimize pain relief, quality of life, and diabetes outcomes, and to measure the procedure's cost effectiveness. A biorepository is also established for future ancillary studies.

The aims of this study were to determine the prevalence of cognitive impairment in hypertensive patients, to identify the most affected cognitive domain, and to observe the association with different parameters of hypertension and other vascular risk factors. A multicentre study was carried out, and 1281 hypertensive patients of both genders and >=21 years of age were included. Data on the following parameters were obtained: cognitive status (Minimal Cognitive Examination), behavioural status (Hospital Anxiety and Depression Scale), blood pressure, anthropometry, and biochemical profile. The average age was 60.2+/-13.5 years (71% female), and the educational level was 9.9+/-5.1 years. Global cognitive impairment was seen in 22.1%, executive dysfunction in 36.2%, and semantic memory impairment in 48.9%. Cognitive impairment was higher in males (36.8% vs. 30.06%) within both the 70-79-year-old and the >=80-year-old (50% vs. 40%) age groups. Abnormal Clock Drawing Test results were related to high pulse pressure (p<0.0036), and abnormal Mini-Boston Naming Test results to both high systolic blood pressure (p<0.052) and pulse pressure (p<0.001). The treated/uncontrolled hypertensive group showed abnormal results both in the Mini Mental State Examination (OR, 0.73; p=0.036) and the Mini-Boston Naming Test (OR, 1.36; p=0.021). Among patients without cognitive impairment (MMSE >24), 29.4% presented executive dysfunction, and 41.5% semantic memory impairment. Cognitive impairment was higher in hypertensive patients than in the general population. Executive functions and semantic memory were the most affected cognitive domains. High systolic blood pressure and pulse pressure were associated with abnormal results in cognitive tests.

AB - Transition metals Cd, Pd and Ag are toxic even at very low concentration. Cd is considered a priority substance; while, Pd and Ag are emerging pollutants. Membrane technologies have been applied for their extraction; however, they require important amounts of reagents, time and energy. Additionally, effective reagents for metal extraction in saline natural waters are limited. In this case, hollow fiber liquid phase micro-extraction with a configuration of solvent bar (SBME) using the ionic liquid Cyphos(r) 101 as extractant is proposed. Optimized conditions for SBME of Cd, Ag and Pd were 50% Cyphos(r) 101 in the organic solution, extraction time 30 min and 800 rpm stirring rate. Leaching was in all cases lower than 0.1%. Metallic concentrations were measured by flame atomic absorption spectroscopy. The method was applied to the extraction of Ag, Cd and Pd in natural water samples. Except for waste water, Pd extraction was higher than 90% in all cases. Cd (~100%) and Ag (93-95%) offered their best results for saline samples. Concluding, the proposed system is a low cost and green methodology that allows a simple and fast extraction of trace pollutants such as Ag, Cd and Pd in different natural waters, including highly saline samples. PMID- 29456128 TI - Transcranial direct current stimulation and constraint-induced therapy in cerebral palsy: A randomized, blinded, sham-controlled clinical trial. AB - : We investigated the safety, feasibility, and efficacy of transcranial direct current stimulation (tDCS) combined with constraint-induced movement therapy (CIMT) in children and young adults with unilateral cerebral palsy. Twenty participants were randomized to receive active or sham tDCS. The intervention consisted of 10 consecutive weekday sessions of tDCS applied to the non-lesioned hemisphere (20 min) concurrently with CIMT (120 min). Participants, caregivers, and interventionists were blinded to group assignment. The primary safety outcome investigated adverse events. The primary behavioral outcome was the Assisting Hand Assessment. All 20 participants (mean age = 12.7 yrs, range = 7.4-21.6 years) were evaluated for the primary outcomes. No serious adverse events occurred, and the most commonly reported minor adverse events were headache and itchiness. Both groups demonstrated a significant improvement in hand function after the intervention, although no significant effect of tDCS was observed (between-group difference = -2.18, 95% CI = [-6.48, 2.12], p = 0.30). Although hand function improved overall, no significant differences between intervention groups were found. Children with preserved corticospinal tract circuitry from the lesioned hemisphere, compared to those without, showed greater improvement in hand function (mean difference = 3.04, 95% CI = [-0.64, 6.72], p = 0.099). Our study demonstrates the safety and feasibility of serial sessions of tDCS, and presents preliminary evidence for the effect of CST circuitry on outcomes following tDCS/CIMT. Future work in children with unilateral cerebral palsy should focus on the optimal dosing and consider individual brain circuitry when describing response to combined interventions.

PMID- 29456130 TI - Increments in serum high-density lipoprotein cholesterol over time are not associated with improved outcomes in incident hemodialysis patients. AB - BACKGROUND: Elevated serum high-density lipoprotein cholesterol (HDL-C) has not been associated with better cardiovascular (CV) and all-cause mortality in hemodialysis patients. However, the association between change in HDL over time and mortality has not been fully examined. OBJECTIVE: In a nationally representative cohort of incident hemodialysis patients who had available HDL data at baseline and 6 months after dialysis initiation, we studied the association of change in HDL-C during the first 6 months of dialysis with all cause and CV mortality. METHODS: Associations between HDL-C change and mortality were determined in Cox proportional hazard regression models with adjustment for multiple variables. RESULTS: In case-mix models, there was a J-shaped association between change in HDL-C and mortality, such that quartiles 1 (<-5 mg/dL) and 4 (>=7 mg/dL) were each associated with higher all-cause (hazard ratio, 1.32 [95% confidence interval, 1.21-1.45] and 1.09 [1.01-1.18]) and CV (1.28 [1.06-1.55] and 1.23 [1.04-1.45]) death risk, respectively. In fully adjusted models that included indices of malnutrition and inflammation, the higher death risk observed in the lowest quartile was attenuated, whereas the highest quartile continued to demonstrate significantly higher all-cause (1.11 [1.02-1.20]) and CV mortality (1.15 [1.00-1.32]). These associations persisted across various subgroups. CONCLUSIONS: Although malnutrition and inflammation may explain the increased risk for mortality in patients with decreasing serum HDL-C concentrations over time, these indices do not mitigate the elevated risk in patients with rising serum HDL-C. We found that increasing serum HDL-C over time is paradoxically associated with worse outcomes in incident hemodialysis patients. PMID- 29456131 TI - High expression of CC chemokine receptor 5 (CCR5) promotes disease progression in patients with B-cell non-Hodgkin lymphomas. AB - Chemokines are small proteins, that regulate cell migration in many physiological and pathologic processes in human body. They are also responsible for cancer progression. CC chemokine receptor 5 (CCR5) is responsible for cell recruitment in inflammation and may be involved in antitumor immune response controlling. Aberrant CCR5 can be found in different kind of cancers, not only hematological, but also solid tumors. Non-Hodgkin lymphomas consist of many lymphoma subtypes. They predominantly derive from B cells and can have very heterogenous clinical course. That is why new prognostic factors are still needed to predict and select high-risk patients. We evaluated CCR5 expression in lymph nodes derived from B cell lymphomas in comparison to reactive lymphatic tissue (reactive lymph nodes): samples of lymphoma lymph nodes, peripheral blood, and bone marrow aspirates of patients with B-cell non-Hodgkin lymphoma were taken at diagnosis and after completed chemotherapy. Gene expression was determined by the reverse transcription-polymerase chain reaction method. Expression was estimated from 0AU (no amplificate signal) to 3AU (maximal amplificate signal). We found low CCR5 expression in lymphomas and reactive lymph nodes. Higher CCR5 gene expression in lymphoma patients was correlated with advanced stage of the disease, high proliferation index (Ki-67), and international prognostic index. Patients with higher CCR5 expression had shorter survival. CCR5 high expression may have a role in non-Hodgkin's lymphomas progression and can influence patients' survival. CCR5 also can become an immunotherapeutic target for novel treatment options in the future as well as new prognostic factor. PMID- 29456132 TI - CSF lamp2 concentrations are decreased in female Parkinson's disease patients with LRRK2 mutations. AB - Lysosome-associated membrane glycoprotein 2 (lamp2) plays critical roles in chaperone-mediated autophagy (CMA) and macroautophagy. Its isoform lamp2a is decreased in Parkinson's disease (PD) substantia nigra. Mutations in the leucine rich repeat kinase 2 (LRRK2) gene are the most known common cause of late-onset PD; although LRRK2 is thought to regulate macroautophagy, the influence of LRRK2 mutations on lamp2 concentrations in the CNS is unknown. To examine this issue we compared lamp2 levels in cerebrospinal fluid (CSF) between sporadic PD (sPD) patients (n = 31), LRRK2 PD patients (n = 20), and healthy control subjects with or without LRRK2 mutations (LRRK2 CTL = 30, CTL = 27). We also examined lamp2's correlations with age, oxidative stress, PD progression, and PD duration. Median lamp2 concentrations (pg/mL) were LRRK2 PD = 127, sPD = 333, CTL = 436, and LRRK2 CTL = 412. Log-transformed lamp2 concentrations, adjusting for gender effects (and excluding male LRRK2 PD patients because of low number), were lower in female LRRK2 PD patients than in LRRK2 CTL (p = 0.002) and CTL (p = 0.005) subjects (p = 0.06 for lamp2 comparison between female LRRK2 PD patients and sPD patients). Lamp2 did not appear to be associated with age, PD progression, or PD duration; however, three of four Spearman rho values for correlations between lamp2 and oxidative stress markers in PD subjects were >=0.30. These findings suggest that CSF lamp2 concentrations may be decreased in female LRRK2 PD patients compared to healthy individuals with or without LRRK2 mutations. PMID- 29456133 TI - No evidence for systematic white matter correlates of dyslexia: An Activation Likelihood Estimation meta-analysis. AB - Dyslexia is a prevalent neurodevelopmental disorder, characterized by reading and spelling difficulties. Beyond the behavioral and functional correlates of this condition, a growing number of studies have explored structural differences between individuals with dyslexia and typically developing individuals. To date, findings remain disparate - some studies suggest differences in fractional anisotropy (FA), an indirect measure of white matter integrity, whereas others do not identify significant disparities. Here, we synthesized the existing literature on this topic by conducting a meta-analysis of Diffusion Tensor Imaging (DTI) studies investigating white matter correlates of dyslexia via voxel based analyses (VBA) of FA. Our results showed no reliable clusters underlying differences between dyslexics and typical individuals, after correcting for multiple comparisons (false discovery rate correction). Because group comparisons might be too coarse to yield subtle differences, we further explored differences in FA as a function of reading ability, measured on a continuous scale. Consistent with our initial findings, reading ability was not associated with reliable differences in white matter integrity. These findings nuance the current view of profound, structural differences underlying reading ability and its associated disorders, and suggest that their neural correlates might be more subtle than previously thought. PMID- 29456134 TI - Parietal control network activation during memory tasks may be associated with the co-occurrence of externally and internally directed cognition: A cross function meta-analysis. AB - Functional neuroimaging studies on episodic memory retrieval consistently indicated the activation of the precuneus (PCU), mid-cingulate cortex (MCC), and lateral intraparietal sulcus (latIPS) regions. Although studies typically interpreted these activations in terms of memory retrieval processes, resting state functional connectivity data indicate that these regions are part of the frontoparietal control network, suggesting a more general, cross-functional role. In this regard, this study proposes a novel hypothesis which suggests that the parietal control network plays a strong role in accommodating the co-occurrence of externally directed cognition (EDC) and internally directed cognition (IDC), which are typically antagonistic to each other. To evaluate how well this dual cognitive processes hypothesis can account for parietal activation patterns during memory tasks, this study provides a cross-function meta-analysis involving 3 different memory paradigms, namely, retrieval success (hit > correct rejection), repetition enhancement (repeated > novel), and subsequent forgetting (forgotten > remembered). Common to these paradigms is that the target condition may involve both EDC (stimulus processing and motor responding) and IDC (intentional remembering, involuntary awareness of previous encounter, or task unrelated thoughts) strongly, whereas the reference condition may involve EDC to a greater extent, but IDC to a lesser extent. Thus, the dual cognitive processes hypothesis predicts that each of these paradigms will activate similar, overlapping PCU, MCC, and latIPS regions. The results were fully consistent with the prediction, supporting the dual cognitive processes hypothesis. Evidence from relevant prior studies suggests that the dual cognitive processes hypothesis may also apply to non-memory domain tasks. PMID- 29456135 TI - Pericyte ALK5/TIMP3 Axis Contributes to Endothelial Morphogenesis in the Developing Brain. AB - The murine embryonic blood-brain barrier (BBB) consists of endothelial cells (ECs), pericytes (PCs), and basement membrane. Although PCs are critical for inducing vascular stability, signaling pathways in PCs that regulate EC morphogenesis during BBB development remain unexplored. Herein, we find that murine embryos lacking the transforming growth factor beta (TGF-beta) receptor activin receptor-like kinase 5 (Alk5) in brain PCs (mutants) develop gross germinal matrix hemorrhage-intraventricular hemorrhage (GMH-IVH). The germinal matrix (GM) is a highly vascularized structure rich in neuronal and glial precursors. We show that GM microvessels of mutants display abnormal dilation, reduced PC coverage, EC hyperproliferation, reduced basement membrane collagen, and enhanced perivascular matrix metalloproteinase activity. Furthermore, ALK5 depleted PCs downregulate tissue inhibitor of matrix metalloproteinase 3 (TIMP3), and TIMP3 administration to mutants improves endothelial morphogenesis and attenuates GMH-IVH. Overall, our findings reveal a key role for PC ALK5 in regulating brain endothelial morphogenesis and a substantial therapeutic potential for TIMP3 during GMH-IVH. PMID- 29456136 TI - A Sex Chromosome piRNA Promotes Robust Dosage Compensation and Sex Determination in C. elegans. AB - In metazoans, Piwi-related Argonaute proteins engage piRNAs (Piwi-interacting small RNAs) to defend the genome against invasive nucleic acids, such as transposable elements. Yet many organisms-including worms and humans-express thousands of piRNAs that do not target transposons, suggesting that piRNA function extends beyond genome defense. Here, we show that the X chromosome derived piRNA 21ux-1 downregulates XOL-1 (XO Lethal), a master regulator of X chromosome dosage compensation and sex determination in Caenorhabditis elegans. Mutations in 21ux-1 and several Piwi-pathway components sensitize hermaphrodites to dosage compensation and sex determination defects. We show that the piRNA pathway also targets xol-1 in C. briggsae, a nematode species related to C. elegans. Our findings reveal physiologically important piRNA-mRNA interactions, raising the possibility that piRNAs function broadly to ensure robust gene expression and germline development. PMID- 29456137 TI - Lineage-Biased Hematopoietic Stem Cells Are Regulated by Distinct Niches. AB - The spatial localization of hematopoietic stem cells (HSCs) in the bone marrow (BM) remains controversial, with some studies suggesting that they are maintained in homogeneously distributed niches while others have suggested the contributions of distinct niche structures. Subsets of quiescent HSCs have been reported to associate with megakaryocytes (MK) or arterioles in the BM. However, these HSC subsets have not been prospectively defined. Here, we show that platelet and myeloid-biased HSCs, marked by von Willebrand factor (vWF) expression, are highly enriched in MK niches. Depletion of MK selectively expands vWF+ HSCs, whereas the depletion of NG2+ arteriolar niche cells selectively depletes vWF- lymphoid biased HSCs. In addition, MK depletion compromises vWF+ HSC function by reducing their long-term self-renewal capacity and eliminating their lineage bias after transplantation. These studies demonstrate the existence of two spatially and functionally separate BM niches for HSC subsets with distinct developmental potential. PMID- 29456138 TI - The InR/Akt/TORC1 Growth-Promoting Signaling Negatively Regulates JAK/STAT Activity and Migratory Cell Fate during Morphogenesis. AB - Cell growth and cell differentiation are two distinct yet coupled developmental processes, but how they are coordinated is not well understood. During Drosophila oogenesis, we found that the growth-promoting InR/Akt/TOR pathway was involved in suppressing the fate determination of the migratory border cells. The InR/Akt/TOR pathway signals through TOR and Raptor, components of TORC1, to downregulate the JAK/STAT pathway, which is necessary and sufficient for border cell fate determination. TORC1 promotes the protein stability of SOCS36E, the conserved negative regulator of JAK/STAT signaling, through physical interaction, suggesting that TORC1 acts as a key regulator coordinating both cell growth and cell differentiation. PMID- 29456139 TI - Selective Attention Gates the Interactive Crossmodal Coupling between Perceptual Systems. AB - Sensory cortical systems often activate in parallel, even when stimulation is experienced through a single sensory modality [1-3]. Co-activations may reflect the interactive coupling between information-linked cortical systems or merely parallel but independent sensory processing. We report causal evidence consistent with the hypothesis that human somatosensory cortex (S1), which co-activates with auditory cortex during the processing of vibrations and textures [4-9], interactively couples to cortical systems that support auditory perception. In a series of behavioral experiments, we used transcranial magnetic stimulation (TMS) to probe interactions between the somatosensory and auditory perceptual systems as we manipulated attention state. Acute TMS over S1 impairs auditory frequency perception when subjects simultaneously attend to auditory and tactile frequency, but not when attention is directed to audition alone. Auditory frequency perception is unaffected by TMS over visual cortex, thus confirming the privileged interactions between the somatosensory and auditory systems in temporal frequency processing [10-13]. Our results provide a key demonstration that selective attention can modulate the functional properties of cortical systems thought to support specific sensory modalities. The gating of crossmodal coupling by selective attention may critically support multisensory interactions and feature-specific perception. PMID- 29456140 TI - Visual Selective Attention in Mice. AB - Visual selective attention is a fundamental cognitive ability that allows us to process relevant visual stimuli while ignoring irrelevant distracters and has been extensively studied in human and non-human primate subjects. Mice have emerged as a powerful animal model for studying aspects of the visual system but have not yet been shown to exhibit visual selective attention. Differences in the organization of the visual systems of primates and mice raise the possibility that selective visual attention might not be present in mice, at least not in the forms that are well established in primates. Here, we tested for selective visual attention in mice by using three behavioral paradigms adapted from classic studies of attention. In a Posner-style cueing task, a spatial cue indicated the probable location of the relevant visual event, and we found that accuracy was higher and reaction times were shorter on validly cued trials. In a cue versus no cue task, an informative spatial cue was provided on half the trials, and mice had higher accuracy and shorter reaction times with spatial cues and also lower detection thresholds measured from psychometric curves. In a filter task, the spatial cue indicated the location of the relevant visual event, and we found that mice could be trained to ignore irrelevant but otherwise identical visual events at uncued locations. Together, these results demonstrate that mice exhibit visual selective attention, paving the way to use classic attention paradigms in mice to study the genetic and neuronal circuit mechanisms of selective attention. PMID- 29456141 TI - Inhomogeneous Encoding of the Visual Field in the Mouse Retina. AB - Stimulus characteristics of the mouse's visual field differ above and below the skyline. Here, we show for the first time that retinal ganglion cells (RGCs), the output neurons of the retina, gradually change their functional properties along the ventral-dorsal axis to allow better representation of the different stimulus characteristics. We conducted two-photon targeted recordings of transient Offalpha-RGCs and found that they gradually became more sustained along the ventral-dorsal axis, revealing >5-fold-longer duration responses in the dorsal retina. Using voltage-clamp recordings, pharmacology, and genetic manipulation, we demonstrated that the primary rod pathway underlies this variance. Our findings challenge the current belief that RGCs of the same subtype exhibit the same light responses, regardless of retinal location, and suggest that networks underlying RGC responses may change with retinal location to enable optimized sampling of the visual image. PMID- 29456143 TI - Neocortical Association Cell Types in the Forebrain of Birds and Alligators. AB - The avian dorsal telencephalon has two vast territories, the nidopallium and the mesopallium, both of which have been shown to contribute substantially to higher cognitive functions. From their connections, these territories have been proposed as equivalent to mammalian neocortical layers 2 and 3, various neocortical association areas, or the amygdala, but whether these are analogies or homologies by descent is unknown. We investigated the molecular profiles of the mesopallium and the nidopallium with RNA-seq. Gene expression experiments established that the mesopallium, but not the nidopallium, shares a transcription factor network with the intratelencephalic class of neocortical neurons, which are found in neocortical layers 2, 3, 5, and 6. Experiments in alligators demonstrated that these neurons are also abundant in the crocodilian cortex and form a large mesopallium-like structure in the dorsal ventricular ridge. Together with previous work, these molecular findings indicate a homology by descent for neuronal cell types of the avian dorsal telencephalon with the major excitatory cell types of mammalian neocortical circuits: the layer 4 input neurons, the deep layer output neurons, and the multi-layer intratelencephalic association neurons. These data raise the interesting possibility that avian and primate lineages evolved higher cognitive abilities independently through parallel expansions of homologous cell populations. PMID- 29456142 TI - The FERONIA Receptor Kinase Maintains Cell-Wall Integrity during Salt Stress through Ca2+ Signaling. AB - Cells maintain integrity despite changes in their mechanical properties elicited during growth and environmental stress. How cells sense their physical state and compensate for cell-wall damage is poorly understood, particularly in plants. Here we report that FERONIA (FER), a plasma-membrane-localized receptor kinase from Arabidopsis, is necessary for the recovery of root growth after exposure to high salinity, a widespread soil stress. The extracellular domain of FER displays tandem regions of homology with malectin, an animal protein known to bind di glucose in vitro and important for protein quality control in the endoplasmic reticulum. The presence of malectin-like domains in FER and related receptor kinases has led to widespread speculation that they interact with cell-wall polysaccharides and can potentially serve a wall-sensing function. Results reported here show that salinity causes softening of the cell wall and that FER is necessary to sense these defects. When this function is disrupted in the fer mutant, root cells explode dramatically during growth recovery. Similar defects are observed in the mur1 mutant, which disrupts pectin cross-linking. Furthermore, fer cell-wall integrity defects can be rescued by treatment with calcium and borate, which also facilitate pectin cross-linking. Sensing of these salinity-induced wall defects might therefore be a direct consequence of physical interaction between the extracellular domain of FER and pectin. FER-dependent signaling elicits cell-specific calcium transients that maintain cell-wall integrity during salt stress. These results reveal a novel extracellular toxicity of salinity, and identify FER as a sensor of damage to the pectin-associated wall. PMID- 29456145 TI - The Interrelationships of Land Plants and the Nature of the Ancestral Embryophyte. AB - The evolutionary emergence of land plant body plans transformed the planet. However, our understanding of this formative episode is mired in the uncertainty associated with the phylogenetic relationships among bryophytes (hornworts, liverworts, and mosses) and tracheophytes (vascular plants). Here we attempt to clarify this problem by analyzing a large transcriptomic dataset with models that allow for compositional heterogeneity between sites. Zygnematophyceae is resolved as sister to land plants, but we obtain several distinct relationships between bryophytes and tracheophytes. Concatenated sequence analyses that can explicitly accommodate site-specific compositional heterogeneity give more support for a mosses-liverworts clade, "Setaphyta," as the sister to all other land plants, and weak support for hornworts as the sister to all other land plants. Bryophyte monophyly is supported by gene concatenation analyses using models explicitly accommodating lineage-specific compositional heterogeneity and analyses of gene trees. Both maximum-likelihood analyses that compare the fit of each gene tree to proposed species trees and Bayesian supertree estimation based on gene trees support bryophyte monophyly. Of the 15 distinct rooted relationships for embryophytes, we reject all but three hypotheses, which differ only in the position of hornworts. Our results imply that the ancestral embryophyte was more complex than has been envisaged based on topologies recognizing liverworts as the sister lineage to all other embryophytes. This requires many phenotypic character losses and transformations in the liverwort lineage, diminishes inconsistency between phylogeny and the fossil record, and prompts re-evaluation of the phylogenetic affinity of early land plant fossils, the majority of which are considered stem tracheophytes. PMID- 29456144 TI - Global Demand for Natural Resources Eliminated More Than 100,000 Bornean Orangutans. AB - Unsustainable exploitation of natural resources is increasingly affecting the highly biodiverse tropics [1, 2]. Although rapid developments in remote sensing technology have permitted more precise estimates of land-cover change over large spatial scales [3-5], our knowledge about the effects of these changes on wildlife is much more sparse [6, 7]. Here we use field survey data, predictive density distribution modeling, and remote sensing to investigate the impact of resource use and land-use changes on the density distribution of Bornean orangutans (Pongo pygmaeus). Our models indicate that between 1999 and 2015, half of the orangutan population was affected by logging, deforestation, or industrialized plantations. Although land clearance caused the most dramatic rates of decline, it accounted for only a small proportion of the total loss. A much larger number of orangutans were lost in selectively logged and primary forests, where rates of decline were less precipitous, but where far more orangutans are found. This suggests that further drivers, independent of land-use change, contribute to orangutan loss. This finding is consistent with studies reporting hunting as a major cause in orangutan decline [8-10]. Our predictions of orangutan abundance loss across Borneo suggest that the population decreased by more than 100,000 individuals, corroborating recent estimates of decline [11]. Practical solutions to prevent future orangutan decline can only be realized by addressing its complex causes in a holistic manner across political and societal sectors, such as in land-use planning, resource exploitation, infrastructure development, and education, and by increasing long-term sustainability [12]. VIDEO ABSTRACT. PMID- 29456146 TI - A Comprehensive and Dated Phylogenomic Analysis of Butterflies. AB - Butterflies (Papilionoidea), with over 18,000 described species [1], have captivated naturalists and scientists for centuries. They play a central role in the study of speciation, community ecology, biogeography, climate change, and plant-insect interactions and include many model organisms and pest species [2, 3]. However, a robust higher-level phylogenetic framework is lacking. To fill this gap, we inferred a dated phylogeny by analyzing the first phylogenomic dataset, including 352 loci (> 150,000 bp) from 207 species representing 98% of tribes, a 35-fold increase in gene sampling and 3-fold increase in taxon sampling over previous studies [4]. Most data were generated with a new anchored hybrid enrichment (AHE) [5] gene kit (BUTTERFLY1.0) that includes both new and frequently used (e.g., [6]) informative loci, enabling direct comparison and future dataset merging with previous studies. Butterflies originated around 119 million years ago (mya) in the late Cretaceous, but most extant lineages diverged after the Cretaceous-Paleogene (K-Pg) mass-extinction 65 mya. Our analyses support swallowtails (Papilionidae) as sister to all other butterflies, followed by skippers (Hesperiidae) + the nocturnal butterflies (Hedylidae) as sister to the remainder, indicating a secondary reversal from diurnality to nocturnality. The whites (Pieridae) were strongly supported as sister to brush-footed butterflies (Nymphalidae) and blues + metalmarks (Lycaenidae and Riodinidae). Ant association independently evolved once in Lycaenidae and twice in Riodinidae. This study overturns prior notions of the taxon's evolutionary history, as many long-recognized subfamilies and tribes are para- or polyphyletic. It also provides a much-needed backbone for a revised classification of butterflies and for future comparative studies including genome evolution and ecology. PMID- 29456147 TI - Dynamic Interplay of Value and Sensory Information in High-Speed Decision Making. AB - In dynamic environments, split-second sensorimotor decisions must be prioritized according to potential payoffs to maximize overall rewards. The impact of relative value on deliberative perceptual judgments has been examined extensively [1-6], but relatively little is known about value-biasing mechanisms in the common situation where physical evidence is strong but the time to act is severely limited. In prominent decision models, a noisy but statistically stationary representation of sensory evidence is integrated over time to an action-triggering bound, and value-biases are affected by starting the integrator closer to the more valuable bound. Here, we show significant departures from this account for humans making rapid sensory-instructed action choices. Behavior was best explained by a simple model in which the evidence representation-and hence, rate of accumulation-is itself biased by value and is non-stationary, increasing over the short decision time frame. Because the value bias initially dominates, the model uniquely predicts a dynamic "turn-around" effect on low-value cues, where the accumulator first launches toward the incorrect action but is then re routed to the correct one. This was clearly exhibited in electrophysiological signals reflecting motor preparation and evidence accumulation. Finally, we construct an extended model that implements this dynamic effect through plausible sensory neural response modulations and demonstrate the correspondence between decision signal dynamics simulated from a behavioral fit of that model and the empirical decision signals. Our findings suggest that value and sensory information can exert simultaneous and dynamically countervailing influences on the trajectory of the accumulation-to-bound process, driving rapid, sensory guided actions. PMID- 29456149 TI - Impact of a Universal Medication Schedule on rationalising and understanding of medication; a randomised controlled trial. AB - BACKGROUND: Patients frequently encounter difficulty understanding their prescription drug labels. This problem is more common in patients with limited health literacy (HL). Patients are not always counselled on their medicines by their doctor or pharmacist, therefore this label can be an important source of information. OBJECTIVE: To assess the impact of a Universal Medication Schedule (UMS) on the knowledge and consolidation of a prescription drug regimen compared to standard pharmacy labelling. METHODS: Seventy-six in-patients at a specialised rehabilitation hospital in Dublin, Ireland, were randomised into control (usual care) or intervention (UMS) groups. Adult in-patients, receiving oral medicines, who spoke English fluently were included. Patients with dexterity issues documented, or those unable to provide written informed consent were excluded. The Newest Vital Sign (NVS) and validated HL screening questions measured HL. A five medication regimen was presented to each participant, and they were asked questions to assess their understanding of the medication regimen and were asked to dose out the medications into a 24 h dosette box. Data analysis was conducted using SPSS(r) (IBM Corp.), V23. RESULTS: The majority of participants (n = 76) were Irish (89.5%), male (63.2%) and the median age of participants was 49 years. 46% of participants had a third level qualification, however 14.4% of participants had not completed any formal school examinations. Those in the UMS group displayed better understanding of the prescription regimen than those in the usual care group, but this was not statistically significant. (Mean score 9.28 vs 8.81, p = 0.135). Subgroup analysis did not find any additional benefit of UMS in those with limited health literacy (Mean score 8.56 vs 9.06, p = 0.514) but rather in those who said that they found instructions on tablets hard to understand (Mean score 10.00 vs 8.43, p = 0.019). CONCLUSION: A UMS approach may improve patients understanding and use of their medicines. PMID- 29456150 TI - Antidepressants as antipruritic agents: A review. AB - Pruritus is a concomitant symptom of various underlying disorders viz. dermatological, systemic and psychiatric disorders that provoke the person to scratch the skin. Many natural as well as, antipruritic therapies are usually practiced in the treatment of pruritus including general preventive measures, topical therapies such as cooling agents, antihistamines, anesthetics, capsaicin, corticosteroids, immunomodulators and; systemic therapies including administration of antihistamines, opioid antagonists/agonists, antiepileptic drugs/neuroleptics (e.g., gabapentin and pregabalin), antidepressants (e.g., doxepin, amitriptyline, paroxetine, fluvoxamine, sertraline, escitalopram and mirtazapine) (Patel and Yosipovitch, 2010; Reich et al., 2011; Martin and Padilla, 2015; Eskeland et al., 2016). Topical therapies are the mainstay of treatment of delicate and localized pruritus while other systemic drug therapies are used to treat stern and generalized pruritus.

AB - INTRODUCTION: Sarcoidosis is a complex disease of unknown etiology, with a variable course and highly different forms of presentation. Our objective was to characterize all our patients with sarcoidosis with emphasis on their clinical presentation and to establish differences between patients with sarcoidosis with and without joint involvement. METHODS: We reviewed the medical records of all patients with a diagnosis of sarcoidosis who were treated at the outpatient or inpatient services of the Pablo Tobon Uribe Hospital in Medellin, Colombia, from January 2002 to April 2017. RESULTS: We identified 22 patients with sarcoidosis. There were joint symptoms in 13 of them. All but one of the patients with sarcoidosis affecting the joints had concomitant skin involvement (92%), which was much less frequent in patients without joint involvement (22%) (odds ratio=4.2; P<.001). CONCLUSIONS: Patients with sarcoidosis who have joint involvement have a much higher frequency of concomitant skin involvement. The absence of cutaneous findings in a patient with joint symptoms decreases the likelihood of sarcoidosis.

PMID- 29456155 TI - Rheumatic Syndromes and Occult Tumor: 10-year Experience in a Teaching Hospital. AB - OBJECTIVE: To describe the different clinical characteristics of patients admitted to the Rheumatology Department due to rheumatic manifestations as the first expression of an unknown malignant process. PATIENTS AND METHODS: Retrospective and descriptive observational study involving the review of the medical records of those admitted to rheumatology in the University Hospital of Ciudad Real between January 2007 and August 2017 for initial rheumatic manifestations with a suspicion at discharge of an unknown tumor. RESULTS: In all, 64 patients were identified from more than 500 admissions. The most common rheumatic manifestations were inflammatory low back pain, polyarthralgia, hip pain, thoracic spine pain, cervical pain, polyarthritis and polymyalgia rheumatica. Forty-four percent had low hemoglobin, 70% had elevation of acute phase reactants, 62% had abnormal tumor markers, 76% had metastatic lesions. In 20% the primary tumor was of pulmonary origin and only 26.56% received palliative treatment; 64% died. DISCUSSION: It is important to consider the possibility of an underlying malignant process in the differential diagnosis since its early identification can be determinant for prognosis.

AB - In the present study, a novel model of type-I counter-current chromatography was developed to simplify the separation column manufacture and extend its application ranges. In this system, a multilayer coil was used as the separation column of type-I counter-current chromatography for the first time. The chromatographic performance of this apparatus was evaluated in terms of retention of the stationary phase (Sf), theoretical plate (N) and peak resolution (Rs) using dipeptides and DNP-amino acids as test samples with two classic solvent systems composed of 1-butanol-acetic acid-water (4:1:5, v/v) (BAW) and hexane ethyl acetate-methanol-0.1 M HCl (1:1:1:1, v/v) (HEMW), respectively. The results indicated that the performance was optimal at the revolution speed of 200 rpm. The lower flow rate was more beneficial to retention of stationary phase and peak resolution. Over all results of our study revealed that the new type-I counter current chromatography with a multilayer coil has a high application potential.

AB - A crucial player in immune regulation, FoxP3+ regulatory T cells (Tregs) are drawing attention for their heterogeneity and noncanonical functions. Here, we describe a Treg subpopulation that controls hematopoietic stem cell (HSC) quiescence and engraftment. These Tregs highly expressed an HSC marker, CD150, and localized within the HSC niche in the bone marrow (BM). Specific reduction of BM Tregs achieved by conditional deletion of CXCR4 in Tregs increased HSC numbers in the BM. Adenosine generated via the CD39 cell surface ectoenzyme on niche Tregs protected HSCs from oxidative stress and maintained HSC quiescence. In transplantation settings, niche Tregs prevented allogeneic (allo-) HSC rejection through adenosine and facilitated allo-HSC engraftment. Furthermore, transfer of niche Tregs promoted allo-HSC engraftment to a much greater extent than transfer of other Tregs. These results identify a unique niche-associated Treg subset and adenosine as regulators of HSC quiescence, abundance, and engraftment, further highlighting their therapeutic utility. PMID- 29456158 TI - Autologous iPSC-Based Vaccines Elicit Anti-tumor Responses In Vivo. AB - Cancer cells and embryonic tissues share a number of cellular and molecular properties, suggesting that induced pluripotent stem cells (iPSCs) may be harnessed to elicit anti-tumor responses in cancer vaccines. RNA sequencing revealed that human and murine iPSCs express tumor-associated antigens, and we show here a proof of principle for using irradiated iPSCs in autologous anti tumor vaccines. In a prophylactic setting, iPSC vaccines prevent tumor growth in syngeneic murine breast cancer, mesothelioma, and melanoma models. As an adjuvant, the iPSC vaccine inhibited melanoma recurrence at the resection site and reduced metastatic tumor load, which was associated with fewer Th17 cells and increased CD11b+GR1hi myeloid cells. Adoptive transfer of T cells isolated from vaccine-treated tumor-bearing mice inhibited tumor growth in unvaccinated recipients, indicating that the iPSC vaccine promotes an antigen-specific anti tumor T cell response. Our data suggest an easy, generalizable strategy for multiple types of cancer that could prove highly valuable in clinical immunotherapy.

PMID- 29456161 TI - The effect of LRRK2 mutations on the cholinergic system in manifest and premanifest stages of Parkinson's disease: a cross-sectional PET study. AB - BACKGROUND: Markers of neuroinflammation are increased in some patients with LRRK2 Parkinson's disease compared with individuals with idiopathic Parkinson's disease, suggesting possible differences in disease pathogenesis. Previous PET studies have suggested amplified dopamine turnover and preserved serotonergic innervation in LRRK2 mutation carriers. We postulated that patients with LRRK2 mutations might show abnormalities of central cholinergic activity, even before the diagnosis of Parkinson's disease. METHODS: Between June, 2009, and December, 2015, we recruited participants from four movement disorder clinics in Canada, Norway, and the USA. Patients with Parkinson's disease were diagnosed by movement disorder neurologists on the basis of the UK Parkinson's Disease Society Brain Bank criteria. LRRK2 carrier status was confirmed by bidirectional Sanger sequencing. We used the PET tracer N-11C-methyl-piperidin-4-yl propionate to scan for acetylcholinesterase activity. The primary outcome measure was rate of acetylcholinesterase hydrolysis, calculated using the striatal input method. We compared acetylcholinesterase hydrolysis rates between groups using ANCOVA, with adjustment for age based on the results of linear regression analysis. FINDINGS: We recruited 14 patients with LRRK2 Parkinson's disease, 16 LRRK2 mutation carriers without Parkinson's disease, eight patients with idiopathic Parkinson's disease, and 11 healthy controls. We noted significant between-group differences in rates of acetylcholinesterase hydrolysis in cortical regions (average cortex p=0.009, default mode network-related regions p=0.006, limbic network-related regions p=0.020) and the thalamus (p=0.008). LRRK2 mutation carriers without Parkinson's disease had increased acetylcholinesterase hydrolysis rates compared with healthy controls in the cortex (average cortex, p=0.046). Patients with LRRK2 Parkinson's disease had significantly higher acetylcholinesterase activity in some cortical regions (average cortex p=0.043, default mode network-related regions p=0.021) and the thalamus (thalamus p=0.004) compared with individuals with idiopathic disease. Acetylcholinesterase hydrolysis rates in healthy controls were correlated inversely with age. INTERPRETATION: LRRK2 mutations are associated with significantly increased cholinergic activity in the brain in mutation carriers without Parkinson's disease compared with healthy controls and in LRRK2 mutation carriers with Parkinson's disease compared with individuals with idiopathic disease. Changes in cholinergic activity might represent early and sustained attempts to compensate for LRRK2-related dysfunction, or alteration of acetylcholinesterase in non-neuronal cells.

AB - Interleukin-13(IL-13) might play an important role in driving aggregate bronchitic symptoms pathogenesis. However, none of the studies assessed the interaction between air pollutants exposure and IL-13 gene on the risk of aggregate bronchitic symptoms in non-asthma children. To assess the independent and joint effects of the exposure to air pollution and IL-13 haplotypes on the risk of aggregate bronchitic symptoms, we conducted a cross-sectional study and focused on non-asthma children. The study population consisted of 2944 children. The effect of each air pollutant on the risk of aggregate bronchitic symptoms was estimated as odds ratios per interquartile range (IQR) change. In the multiple logistic regressions, adjusted for confounding factors, the risk of chronic phlegm was associated with PM2.5 exposure (aOR, 1.59; 95% CI, 1.07-2.37 per 12.51MUg/m3 change), O3 exposure (aOR, 1.54 95% CI, 1.05-2.27 per 8.28ppb change) and SO2 exposure (aOR, 1.19; 95% CI, 1.02-1.39 per 0.98ppb change). Our study further provides the evidence that gene-environment interactions between IL-13 haplotype and O3 exposure on chronic phlegm (95% CI for interaction, 1.01-1.38). Identifying children who are more sensitive to air pollution helps us to provide them an efficient prevention to avoid aggregate bronchitic symptoms.

PMID- 29456166 TI - Head stabilisation in fast running lizards. AB - The cyclic patterns of terrestrial animal locomotion are frequently perturbed in natural environments. The terrain can be complex or inclined, the substrate can move unexpectedly and animals can misjudge situations. Loosing stability due to perturbations increases the probability of capture by predators and decreases the chance of successful prey capture and winning intraspecific battles. When controlled corrective actions are necessary to negotiate perturbations, animals rely on their exteroceptive and proprioceptive senses to monitor the environment and their own body movements. The vestibular system in the inner ear perceives linear and angular accelerations. This information enables gaze stabilisation and the creation of a stable, world-bound reference frame for the integration of the information of other senses. During locomotion, both functions are known to be facilitated by head stabilisation in several animals with an erect posture. Animals with a sprawled body posture, however, undergo very large body undulations while running. Using high speed video recordings, we tested whether they nevertheless stabilise their head during running, and how this is influenced by perturbations. We found that running Acanthodactylus boskianus lizards strongly stabilise their head yaw rotations when running on a flat, straight runway: the head rotation amplitude is only 4.76+/-0.99 degrees , while the adjacent trunk part rotates over 27.0+/-3.8 degrees . Lateral head translations are not stabilised (average amplitude of 7.4+/-2.0mm). When the lizards are experimentally perturbed by a large and unexpected lateral substrate movement, lateral translations of both the head and the body decrease (on average by 1.52+/ 0.81mm). At the same time, the rotations of the head and trunk also decrease (on average by 1.62 degrees +/-7.21 degrees ). These results show that head stabilisation intensifies because of the perturbation, which emphasises the importance of vestibular perception and balance in these fast and manoeuvrable animals.

AB - Appropriate and abundant sources of bone-forming osteoblasts are essential for bone tissue engineering. Pluripotent stem cells can self-renew and thereby offer a potentially unlimited supply of osteoblasts, a significant advantage over other cell sources. We generated mouse embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs) from transgenic mice expressing rat 2.3 kb type I collagen promoter-driven green fluorescent protein (Col2.3GFP), a reporter of the osteoblast lineage. We demonstrated that Col2.3GFP ESCs and iPSCs can be successfully differentiated to osteoblast lineage cells that express Col2.3GFP in vitro. We harvested GFP+ osteoblasts differentiated from ESCs. Genome wide gene expression profiles validated that ESC- and iPSC-derived osteoblasts resemble calvarial osteoblasts, and that Col2.3GFP expression serves as a marker for mature osteoblasts. Our results confirm the cell identity of ESC- and iPSC derived osteoblasts and highlight the potential of pluripotent stem cells as a source of osteoblasts for regenerative medicine.

PMID- 29456169 TI - Kinematics of lower limbs during walking are emulated by springy walking model with a compliantly connected, off-centered curvy foot. AB - The dynamics of the center of mass (CoM) during walking and running at various gait conditions are well described by the mechanics of a simple passive spring loaded inverted pendulum (SLIP). Due to its simplicity, however, the current form of the SLIP model is limited at providing any further information about multi segmental lower limbs that generate oscillatory CoM behaviors and their corresponding ground reaction forces. Considering that the dynamics of the CoM are simply achieved by mass-spring mechanics, we wondered whether any of the multi-joint motions could be demonstrated by simple mechanics. In this study, we expand a SLIP model of human locomotion with an off-centered curvy foot connected to the leg by a springy segment that emulates the asymmetric kinematics and kinetics of the ankle joint. The passive dynamics of the proposed expansion of the SLIP model demonstrated the empirical data of ground reaction forces, center of mass trajectories, ankle joint kinematics and corresponding ankle joint torque at various gait speeds. From the mechanically simulated trajectories of the ankle joint and CoM, the motion of lower-limb segments, such as thigh and shank angles, could be estimated from inverse kinematics. The estimation of lower limb kinematics showed a qualitative match with empirical data of walking at various speeds. The representability of passive compliant mechanics for the kinetics of the CoM and ankle joint and lower limb joint kinematics implies that the coordination of multi-joint lower limbs during gait can be understood with a mechanical framework.

PMID- 29456171 TI - A magnetic resonance imaging framework for quantifying intervertebral disc deformation in vivo: Reliability and application to diurnal variations in lumbar disc shape. AB - Low back pain is a significant socioeconomic burden in the United States and lumbar intervertebral disc degeneration is frequently implicated as a cause. The discs play an important mechanical role in the spine, yet the relationship between disc function and back pain is poorly defined. The objective of this work was to develop a technique using magnetic resonance imaging (MRI) and three dimensional modeling to measure in vivo disc deformations. Using this method, we found that disc geometry was measurable with precision less than the in-plane dimensions of a voxel (~100 um, 10% of the MRI pixel size). Furthermore, there was excellent agreement between mean disc height, disc perimeter, disc volume and regional disc height measurements for multiple trials from an individual rater (standard deviation <3.1% across all measurements) and between mean height, perimeter, and volume measurements made by two independent raters (error <1.5% across all measurements). We then used this measurement system to track diurnal deformations in the L5-S1 disc in a young, healthy population (n = 8; age 24.1 +/ 3.3 yrs; 2 M/6F). We measured decreases in the mean disc height (-8%) and volume (-9%) with no changes in perimeter over an eight-hour workday. We found that the largest height losses occurred in the posterior (-13%) and posterior-lateral ( 14%) regions adjacent to the outer annulus fibrosus. Diurnal annulus fibrosus (AF) strains induced by posterior and posterior-lateral height loss may increase the risk for posterior disc herniation or posterior AF tears. These preliminary findings lay a foundation for determining how deviations from normal deformations may contribute to back pain. PMID- 29456172 TI - Effect of pediatric growth on cervical spine kinematics and deformations in automotive crashes. AB - Finite element (FE) models are a powerful tool that can be used to understand injury mechanisms and develop better safety systems. This study aims to extend the understanding of pediatric spine biomechanics, where there is a paucity of studies available. A newly developed and continuously scalable FE model was validated and scaled to 1.5-, 3-, 6-, 10-, 14- and 18-year-old using a non-linear scaling technique, accounting for local topological changes. The oldest and youngest ages were also scaled using homogeneous geometric scaling. To study the effect of pediatric spinal growth on head kinematics and intervertebral disc strain, the models were exerted to 3.5 g acceleration pulse at the T1 vertebra to simulate frontal, rear and side impacts. It was shown that the head rotation increases with age, but is over predicted when geometrically scaling down from 18 to 1.5-year-old and under predicted when geometrically scaling up from 1.5- to 18-year-old. The strain in the disc, however, showed a clear decrease with age in side impact and for the upper cervical spine in rear impact, indicating a higher susceptibility for neck injury at younger ages. In the frontal impact, no clear age dependence could be seen, suggesting a large contribution from changed facet joint angles, and lower levels of strain, suggesting a lower risk of injury. The results also highlight the benefit of rearward facing children in a seat limiting head lateral motion.

AB - INTRODUCTION: The failure mode and effects analysis (FMEA) has been used as a tool in risk management and quality improvement. The objective of this study is to identify the weaknesses in processes in the clinical trials area, of a Pharmacy Department (PD) with great research activity, in order to improve the safety of the usual procedures. METHODS: A multidisciplinary team was created to analyse each of the critical points, identified as possible failure modes, in the development of clinical trial in the PD. For each failure mode, the possible cause and effect were identified, criticality was calculated using the risk priority number and the possible corrective actions were discussed. RESULTS: Six sub-processes were defined in the development of the clinical trials in PD. The FMEA identified 67 failure modes, being the dispensing and prescription/validation sub-processes the most likely to generate errors. All the improvement actions established in the AMFE were implemented in the Clinical Trials area. DISCUSSION: The FMEA is a useful tool in proactive risk management because it allows us to identify where we are making mistakes and analyze the causes that originate them, to prioritize and to adopt solutions to risk reduction. The FMEA improves process safety and quality in PD. PMID- 29456174 TI - Bilateral maculopathy after exposure to a laser pointer: Optical coherence tomography angiography findings. AB - CASE REPORT: A 36-year-old man went to the emergency department the day after exposure to a laser pointer. Funduscopy revealed dispersed macular pigment alterations, and optical coherence tomography showed a disruption of the retinal layers. The visual acuity was counting fingers in both eyes. Nine months later, optical coherence tomography angiography showed a rarefaction in the choriocapillaris vascular flow in the area of the laser injuries. DISCUSSION: The retinal layer mainly damaged by the laser injury was the retinal pigment epithelium. However, it is suggested that the laser injury could involve tissues beyond the retinal pigment epithelium, since a rarefaction of the choriocapillaris was found after exposure to the laser. PMID- 29456175 TI - Metformin-Induced Lactic Acidosis (MILA): Review of current diagnostic paradigm. AB - A new diagnostic paradigm has been proposed to better categorize causes of Metformin-Associated Lactic Acidosis (MALA). The diagnostic criteria defines a link between Metformin and lactic acidosis if lactate is >5mmol/L, Ph<7.35 and Metformin assay >5mg/L. Metformin assays are not readily available in emergency departments including nationwide Veteran's Affairs Hospitals; thereby making this proposed classification tool difficult to use in today's clinical practice. We describe a case report of a 45-year-old male, who took twice the amount of Metformin prescribed and presented with Metformin-induced lactic acidosis. According to the new criterion, our case would be classified as "Lactic Acidosis in Metformin-Treated Patients (LAMT)." However, the term LAMT does not distinguish between a septic patient taking Metformin with lactic acidosis, and a patient who ingested toxic amounts of Metformin and has lactic acidosis (in absence of Metformin assay). Our case highlights the importance of medication reconciliation done on arrival to emergency department. Timing and dosing of Metformin in patients who present to the emergency department with lactic acidosis may cinch the diagnosis of Metformin-Induced Lactic Acidosis (MILA) in the absence of a Metformin assay but in the right clinical context.

PMID- 29456178 TI - HOXB4 Promotes Hemogenic Endothelium Formation without Perturbing Endothelial Cell Development. AB - Generation of hematopoietic stem cells (HSCs) from pluripotent stem cells, in vitro, holds great promise for regenerative therapies. Primarily, this has been achieved in mouse cells by overexpression of the homeotic selector protein HOXB4. The exact cellular stage at which HOXB4 promotes hematopoietic development, in vitro, is not yet known. However, its identification is a prerequisite to unambiguously identify the molecular circuits controlling hematopoiesis, since the activity of HOX proteins is highly cell and context dependent. To identify that stage, we retrovirally expressed HOXB4 in differentiating mouse embryonic stem cells (ESCs). Through the use of Runx1(-/-) ESCs containing a doxycycline inducible Runx1 coding sequence, we uncovered that HOXB4 promoted the formation of hemogenic endothelium cells without altering endothelial cell development. Whole-transcriptome analysis revealed that its expression mediated the upregulation of transcription of core transcription factors necessary for hematopoiesis, culminating in the formation of blood progenitors upon initiation of Runx1 expression. PMID- 29456179 TI - The Chromatin Remodeler BPTF Activates a Stemness Gene-Expression Program Essential for the Maintenance of Adult Hematopoietic Stem Cells. AB - Self-renewal and differentiation of adult stem cells are tightly regulated partly through configuration of chromatin structure by chromatin remodelers. Using knockout mice, we here demonstrate that bromodomain PHD finger transcription factor (BPTF), a component of the nucleosome remodeling factor (NURF) chromatin remodeling complex, is essential for maintaining the population size of hematopoietic stem/progenitor cells (HSPCs), including long-term hematopoietic stem cells (HSCs). Bptf-deficient HSCs are defective in reconstituted hematopoiesis, and hematopoietic-specific knockout of Bptf caused profound defects including bone marrow failure and anemia. Genome-wide transcriptome profiling revealed that BPTF loss caused downregulation of HSC-specific gene expression programs, which contain several master transcription factors (Meis1, Pbx1, Mn1, and Lmo2) required for HSC maintenance and self-renewal. Furthermore, we show that BPTF potentiates the chromatin accessibility of key HSC "stemness" genes. These results demonstrate an essential requirement of the chromatin remodeler BPTF and NURF for activation of "stemness" gene-expression programs and proper function of adult HSCs. PMID- 29456180 TI - RAS Regulates the Transition from Naive to Primed Pluripotent Stem Cells. AB - The transition from naive to primed state of pluripotent stem cells is hallmarked by epithelial-mesenchymal transition, metabolic switch from oxidative phosphorylation to aerobic glycolysis, and changes in the epigenetic landscape. Since these changes are also seen as putative hallmarks of neoplastic cell transformation, we hypothesized that oncogenic pathways may be involved in this process. We report that the activity of RAS is repressed in the naive state of mouse embryonic stem cells (ESCs) and that all three RAS isoforms are significantly activated upon early differentiation induced by LIF withdrawal, embryoid body formation, or transition to the primed state. Forced expression of active RAS and RAS inhibition have shown that RAS regulates glycolysis, CADHERIN expression, and the expression of repressive epigenetic marks in pluripotent stem cells. Altogether, this study indicates that RAS is located at a key junction of early ESC differentiation controlling key processes in priming of naive cells. PMID- 29456181 TI - An Ultraconserved Element Containing lncRNA Preserves Transcriptional Dynamics and Maintains ESC Self-Renewal. AB - Ultraconserved elements (UCEs) show the peculiar feature to retain extended perfect sequence identity among human, mouse, and rat genomes. Most of them are transcribed and represent a new family of long non-coding RNAs (lncRNAs), the transcribed UCEs (T-UCEs). Despite their involvement in human cancer, the physiological role of T-UCEs is still unknown. Here, we identify a lncRNA containing the uc.170+, named T-UCstem1, and provide in vitro and in vivo evidence that it plays essential roles in embryonic stem cells (ESCs) by modulating cytoplasmic miRNA levels and preserving transcriptional dynamics. Specifically, while T-UCstem1::miR-9 cytoplasmic interplay regulates ESC proliferation by reducing miR-9 levels, nuclear T-UCstem1 maintains ESC self renewal and transcriptional identity by stabilizing polycomb repressive complex 2 on bivalent domains. Altogether, our findings provide unprecedented evidence that T-UCEs regulate physiological cellular functions and point to an essential role of T-UCstem1 in preserving ESC identity. PMID- 29456182 TI - Mitochondrial Dysfunctions Contribute to Hypertrophic Cardiomyopathy in Patient iPSC-Derived Cardiomyocytes with MT-RNR2 Mutation. AB - Hypertrophic cardiomyopathy (HCM) is the most common cause of sudden cardiac death in young individuals. A potential role of mtDNA mutations in HCM is known. However, the underlying molecular mechanisms linking mtDNA mutations to HCM remain poorly understood due to lack of cell and animal models. Here, we generated induced pluripotent stem cell-derived cardiomyocytes (HCM-iPSC-CMs) from human patients in a maternally inherited HCM family who carry the m.2336T>C mutation in the mitochondrial 16S rRNA gene (MT-RNR2). The results showed that the m.2336T>C mutation resulted in mitochondrial dysfunctions and ultrastructure defects by decreasing the stability of 16S rRNA, which led to reduced levels of mitochondrial proteins. The ATP/ADP ratio and mitochondrial membrane potential were also reduced, thereby elevating the intracellular Ca2+ concentration, which was associated with numerous HCM-specific electrophysiological abnormalities. Our findings therefore provide an innovative insight into the pathogenesis of maternally inherited HCM. PMID- 29456183 TI - Modeling Human Cardiac Hypertrophy in Stem Cell-Derived Cardiomyocytes. AB - Cardiac hypertrophy accompanies many forms of cardiovascular diseases. The mechanisms behind the development and regulation of cardiac hypertrophy in the human setting are poorly understood, which can be partially attributed to the lack of a human cardiomyocyte-based preclinical test system recapitulating features of diseased myocardium. The objective of our study is to determine whether human embryonic stem cell-derived cardiomyocytes (hESC-CMs) subjected to mechanical stretch can be used as an adequate in vitro model for studying molecular mechanisms of cardiac hypertrophy. We show that hESC-CMs subjected to cyclic stretch, which mimics mechanical overload, exhibit essential features of a hypertrophic state on structural, functional, and gene expression levels. The presented hESC-CM stretch approach provides insight into molecular mechanisms behind mechanotransduction and cardiac hypertrophy and lays groundwork for the development of pharmacological approaches as well as for discovering potential circulating biomarkers of cardiac dysfunction. PMID- 29456184 TI - Quantified F-Actin Morphology Is Predictive of Phagocytic Capacity of Stem Cell Derived Retinal Pigment Epithelium. AB - With stem cell-derived retinal pigment epithelial (RPE) replacement therapies in clinical testing, establishing potency of RPE prior to transplantation is imperative. Phagocytosis of photoreceptor outer segment fragments (POS) is a key indicator of RPE functionality. Comparing RPE derived from different donor human adult RPE stem cell lines, we found that cells were either high-phagocytic or low phagocytic despite sharing phagocytic receptors and ligands, junctional ZO-1, and lack of epithelial-mesenchymal transition. We found that low-phagocytic cells harbored F-actin stress fibers but lacked contiguous lateral circumferential F actin and ezrin-rich microvilli of high-phagocytic cells. Rho kinase inhibition reversed the F-actin phenotype and restored phagocytic capacity to low-phagocytic RPE. Conversely, RhoA activation induced stress fiber formation and reduced phagocytic function of high-phagocytic RPE. These results demonstrate that a stress fiber-rich microfilament cytoskeleton causes phagocytic dysfunction of RPE cells. We propose F-actin assessment as a rapid, sensitive, and quantitative test to identify RPE populations lacking phagocytic capacity. PMID- 29456185 TI - Human iPS-Derived Astroglia from a Stable Neural Precursor State Show Improved Functionality Compared with Conventional Astrocytic Models. AB - In vivo studies of human brain cellular function face challenging ethical and practical difficulties. Animal models are typically used but display distinct cellular differences. One specific example is astrocytes, recently recognized for contribution to neurological diseases and a link to the genetic risk factor apolipoprotein E (APOE). Current astrocytic in vitro models are questioned for lack of biological characterization. Here, we report human induced pluripotent stem cell (hiPSC)-derived astroglia (NES-Astro) developed under defined conditions through long-term neuroepithelial-like stem (ltNES) cells. We characterized NES-Astro and astrocytic models from primary sources, astrocytoma (CCF-STTG1), and hiPSCs through transcriptomics, proteomics, glutamate uptake, inflammatory competence, calcium signaling response, and APOE secretion. Finally, we assess modulation of astrocyte biology using APOE-annotated compounds, confirming hits of the cholesterol biosynthesis pathway in adult and hiPSC derived astrocytes. Our data show large diversity among astrocytic models and emphasize a cellular context when studying astrocyte biology.

PMID- 29456186 TI - Neurons Generated by Mouse ESCs with Hippocampal or Cortical Identity Display Distinct Projection Patterns When Co-transplanted in the Adult Brain. AB - The capability of generating neural precursor cells with distinct types of regional identity in vitro has recently opened new opportunities for cell replacement in animal models of neurodegenerative diseases. By manipulating Wnt and BMP signaling, we steered the differentiation of mouse embryonic stem cells (ESCs) toward isocortical or hippocampal molecular identity. These two types of cells showed different degrees of axonal outgrowth and targeted different regions when co-transplanted in healthy or lesioned isocortex or in hippocampus. In hippocampus, only precursor cells with hippocampal molecular identity were able to extend projections, contacting CA3. Conversely, isocortical-like cells were capable of extending long-range axonal projections only when transplanted in motor cortex, sending fibers toward both intra- and extra-cortical targets. Ischemic damage induced by photothrombosis greatly enhanced the capability of isocortical-like cells to extend far-reaching projections. Our results indicate that neural precursors generated by ESCs carry intrinsic signals specifying axonal extension in different environments. PMID- 29456188 TI - Parasitism and the Biodiversity-Functioning Relationship. AB - Species interactions can influence ecosystem functioning by enhancing or suppressing the activities of species that drive ecosystem processes, or by causing changes in biodiversity. However, one important class of species interactions - parasitism - has been little considered in biodiversity and ecosystem functioning (BD-EF) research. Parasites might increase or decrease ecosystem processes by reducing host abundance. Parasites could also increase trait diversity by suppressing dominant species or by increasing within-host trait diversity. These different mechanisms by which parasites might affect ecosystem function pose challenges in predicting their net effects. Nonetheless, given the ubiquity of parasites, we propose that parasite-host interactions should be incorporated into the BD-EF framework. PMID- 29456189 TI - Programmable RNA Cleavage and Recognition by a Natural CRISPR-Cas9 System from Neisseria meningitidis. AB - The microbial CRISPR systems enable adaptive defense against mobile elements and also provide formidable tools for genome engineering. The Cas9 proteins are type II CRISPR-associated, RNA-guided DNA endonucleases that identify double-stranded DNA targets by sequence complementarity and protospacer adjacent motif (PAM) recognition. Here we report that the type II-C CRISPR-Cas9 from Neisseria meningitidis (Nme) is capable of programmable, RNA-guided, site-specific cleavage and recognition of single-stranded RNA targets and that this ribonuclease activity is independent of the PAM sequence. We define the mechanistic feature and specificity constraint for RNA cleavage by NmeCas9 and also show that nuclease null dNmeCas9 binds to RNA target complementary to CRISPR RNA. Finally, we demonstrate that NmeCas9-catalyzed RNA cleavage can be blocked by three families of type II-C anti-CRISPR proteins. These results fundamentally expand the targeting capacities of CRISPR-Cas9 and highlight the potential utility of NmeCas9 as a single platform to target both RNA and DNA.

AB - Mitochondrial crista structure partitions vital cellular reactions and is precisely regulated by diverse cellular signals. Here, we show that, in Drosophila, mitochondrial cristae undergo dynamic remodeling among distinct subcellular regions and the Parkinson's disease (PD)-linked Ser/Thr kinase PINK1 participates in their regulation. Mitochondria increase crista junctions and numbers in selective subcellular areas, and this remodeling requires PINK1 to phosphorylate the inner mitochondrial membrane protein MIC60/mitofilin, which stabilizes MIC60 oligomerization. Expression of MIC60 restores crista structure and ATP levels of PINK1-null flies and remarkably rescues their behavioral defects and dopaminergic neurodegeneration. In an extension to human relevance, we discover that the PINK1-MIC60 pathway is conserved in human neurons, and expression of several MIC60 coding variants in the mitochondrial targeting sequence found in PD patients in Drosophila impairs crista junction formation and causes locomotion deficits. These findings highlight the importance of maintenance and plasticity of crista junctions to cellular homeostasis in vivo.

PMID- 29456193 TI - Changes in shoulder girdle strength in 3 consecutive years in elite adolescent swimmers: a longitudinal cohort study. AB - BACKGROUND: The shoulder complex is highly loaded during swimming. No studies were found analyzing the changes in shoulder girdle strength in young swimmers, through the years. OBJECTIVE: To analyze the changes in strength of internal rotators and external rotators of the arm, lower trapezius and supraspinatus and in the external rotators/internal rotators ratio in young elite swimmers through 3 years. METHODS: 31 adolescent elite swimmers (14-18 years, of both sexes) participated in the study. Isometric strength of the shoulder girdle muscles was performed using a handheld dynamometer during 3 years. RESULTS: For boys absolute data, internal rotators increased from the first to the second (p=0.0001; mean difference 45.6N; 95%CI 26.7-65.0) and third years (p=0.01; mean difference: 32.4; 95%CI: 9.3-55.5). Considering the weight-normalized data, internal rotators increased from the first to the second year (p<0.0001; mean difference: 0.52; 95%CI: 0.26-0.78), external rotators decreased from the first to the third year (p=0.003; mean difference: -0.33; 95%CI: -0.53 to -0.13) and from the second to the third year (p=0.0004; mean difference: -0.29; 95%CI: -0.46 to -0.12) and supraspinatus decreased from the second to the third year (p=0.006; mean difference: -0.17; 95%CI: -0.28 to -0.06). For girls, there were no significant differences in the absolute strength. Considering the weight-normalized data, lower trapezius decreased from the first to the third year (p=0.02; mean difference: -0.15; 95%CI: -0.27 to 0.03). Considering both sexes, the external rotators/internal rotators ratio decreased from the first to the second (p<0.0001; mean difference -0.12N; 95%CI -0.13 to -0.11) and third years (p<0.0001; mean difference -0.15N; 95%CI -0.16 to -0.14). CONCLUSION: Muscle imbalance can occur in the shoulder girdle in young swimmers in 3 years, with increased internal rotators and decreased external rotators and supraspinatus strength in boys, and decreased strength of the lower trapezius in girls. Attention should be given in young swimmers' shoulder girdle muscle balance. PMID- 29456191 TI - Comparative efficacy of low-dose versus standard-dose azithromycin for patients with yaws: a randomised non-inferiority trial in Ghana and Papua New Guinea. AB - BACKGROUND: A dose of 30 mg/kg of azithromycin is recommended for treatment of yaws, a disease targeted for global eradication. Treatment with 20 mg/kg of azithromycin is recommended for the elimination of trachoma as a public health problem. In some settings, these diseases are co-endemic. We aimed to determine the efficacy of 20 mg/kg of azithromycin compared with 30 mg/kg azithromycin for the treatment of active and latent yaws. METHODS: We did a non-inferiority, open label, randomised controlled trial in children aged 6-15 years who were recruited from schools in Ghana and schools and the community in Papua New Guinea. Participants were enrolled based on the presence of a clinical lesion that was consistent with infectious primary or secondary yaws and a positive rapid diagnostic test for treponemal and non-treponemal antibodies. Participants were randomly assigned (1:1) to receive either standard-dose (30 mg/kg) or low-dose (20 mg/kg) azithromycin by a computer-generated random number sequence. Health care workers assessing clinical outcomes in the field were not blinded to the patient's treatment, but investigators involved in statistical or laboratory analyses and the participants were blinded to treatment group. We followed up participants at 4 weeks and 6 months. The primary outcome was cure at 6 months, defined as lesion healing at 4 weeks in patients with active yaws and at least a four-fold decrease in rapid plasma reagin titre from baseline to 6 months in patients with active and latent yaws. Active yaws was defined as a skin lesion that was positive for Treponema pallidum ssp pertenue in PCR testing. We used a non-inferiority margin of 10%. This trial was registered with ClinicalTrials.gov, number NCT02344628. FINDINGS: Between June 12, 2015, and July 2, 2016, 583 (65.1%) of 895 children screened were enrolled; 292 patients were assigned a low dose of azithromycin and 291 patients were assigned a standard dose of azithromycin. 191 participants had active yaws and 392 had presumed latent yaws. Complete follow-up to 6 months was available for 157 (82.2%) of 191 patients with active yaws. In cases of active yaws, cure was achieved in 61 (80.3%) of 76 patients in the low-dose group and in 68 (84.0%) of 81 patients in the standard dose group (difference 3.7%; 95% CI -8.4 to 15.7%; this result did not meet the non-inferiority criterion). There were no serious adverse events reported in response to treatment in either group. The most commonly reported adverse event at 4 weeks was gastrointestinal upset, with eight (2.7%) participants in each group reporting this symptom. INTERPRETATION: In this study, low-dose azithromycin did not meet the prespecified non-inferiority margin compared with standard-dose azithromycin in achieving clinical and serological cure in PCR confirmed active yaws. Only a single participant (with presumed latent yaws) had definitive serological failure. This work suggests that 20 mg/kg of azithromycin is probably effective against yaws, but further data are needed. FUNDING: Coalition for Operational Research on Neglected Tropical Diseases. PMID- 29456195 TI - Mast cell tryptase changes with Aspergillus fumigatus - Host crosstalk in cystic fibrosis patients. AB - Pulmonary and systemic antifungal immunity influences quality of life and survival of people with cystic fibrosis. Aspergillus fumigatus (Af) induces specific IgG and IgE. Mast cells respond to IgE, IgG and direct interactions with Af. Mast cells are the source of the protease tryptase. We aimed at evaluating serum baseline tryptase as a potential biomarker of the Af-host interaction in cystic fibrosis patients. Serum baseline tryptase, IgE and IgG directed to Af extract and Af molecular allergens were measured in 76 cystic fibrosis patients. The main findings were (i) lower levels of serum baseline tryptase in patients displaying specific IgE to Af (p < 0.0001) and (ii) an association between tryptase levels and IgE or IgG responses to Af and ribotoxin (Asp f 1). These findings suggest that serum baseline tryptase is influenced by Af-host interactions and thus might be a marker for mast cell regulation and pulmonary immune defenses.

PMID- 29456197 TI - Clinical usefulness and accuracy of polymerase chain reaction in the detection of bacterial meningitis agents in pediatric cerebrospinal fluid. AB - Bacterial meningitis poses enormous healthcare challenges due to a high mortality, morbidity and sequelae. Neisseria (N.) meningitidis, Haemophilus (H.) influenzae, Streptococcus (S.) pneumoniae and S. agalactiae remain among the most prevalent infectious agents that cause bacterial meningitis in children. The objective of this study was the simultaneous detection of these pathogens in suspected cerebrospinal fluid (CSF) by using multiplex polymerase chain reaction (mPCR) and compare PCR results with standard diagnostics currently used in clinical practice. CSF specimens were obtained from 515 children (<5 years) clinically suspected of having acute bacterial meningitis. Based on bacterial culture, four isolates of salmonella sp and one Citrobacter freundii isolate were identified. The remaining 510 CSF specimens, having negative culture, were subjected to mPCR. Twenty-three (4.51%) CSF samples yielded a PCR positive signal. The pathogens identified were: S. pneumoniae (n=13), H. influenzae (n=7) and N. meningitidis (n=3). S. agalactiae was not detected. Using sequential multiplex PCR, serogrouping of S. pneumoniae revealed 3 different serotypes: serotype 19A (n=6), 19F (n=4) and serotype 23F (n=3). Only the serotype A was identified for the 3N. meningitidis isolates. Despite vaccination, S. pneumoniae remains a leading cause of pediatric invasive disease. Detecting causative organism remains the most critical aspect for management of children with suspected meningitis. PCR method is more sensitive and rapid than culture for detecting the infectious agents. Institution of PCR diagnostics is recommended for early and appropriate therapy. PMID- 29456198 TI - A modified single-loop reconstruction after pancreaticoduodenectomy reduces severity of postoperative pancreatic fistula in high-risk patients. AB - BACKGROUND: Double-loop (DL) reconstruction after pancreaticoduodenectomy (PD), diverting pancreatic from biliary secretions, has been reported to reduce rates and severity of postoperative pancreatic fistula (POPF) compared to single loop (SL) reconstruction at the price of prolonged operative duration. This study investigated the feasibility of a new reconstruction method combining the advantages of DL with the simplicity of SL in patients with high-risk pancreas. METHODS: A modified single-loop (mSL) reconstruction was used in patients undergoing PD with a soft pancreatic remnant and a pancreatic duct smaller than 3 mm (n = 50). The loop between the pancreatic and the biliary anastomoses was left longer and a side-to-side jejunojejunal anastomosis was performed between them at the lowest point to promote isolated flow of pancreatic and biliary secretions. Rate and severity of POPF, mortality, duration of surgery, and POPF-associated morbidity were compared to those of 50 matched patients with SL and 25 patients with DL reconstruction. RESULTS: Duration of surgery was 57 min longer for DL, but equal for mSL and SL. The POPF rate did not differ between the three groups. The severity of POPF was more pronounced in the SL group (62% grade C: p = 0.011). Mortality and major morbidity were lower and hospital stay shorter in the mSL and DL groups compared to the SL group. CONCLUSIONS: The new mSL reconstruction was safer than conventional SL and faster to perform than DL reconstruction in patients with a high-risk pancreas. It did not influence the rate of POPF, but reduced its severity, leading to less major morbidity and mortality. PMID- 29456199 TI - The liver-first approach for synchronous colorectal liver metastases: more than a decade of experience in a single centre. AB - BACKGROUND: The feasibility of the liver-first approach for synchronous colorectal liver metastases (CRLM) has been established. We sought to assess the short-term and long-term outcomes for these patients. METHODS: Outcomes of patients who underwent a liver-first approach for CRLM between 2005 and 2015 were retrospectively evaluated from a prospective database. RESULTS: Of the 92 patients planned to undergo the liver-first strategy, the paradigm could be completed in 76.1%. Patients with concurrent extrahepatic disease failed significantly more often in completing the protocol (67% versus 21%; p = 0.03). Postoperative morbidity and mortality were 31.5% and 3.3% following liver resection and 30.9% and 0% after colorectal surgery. Of the 70 patients in whom the paradigm was completed, 36 patients (51.4%) developed recurrent disease after a median interval of 20.9 months. The median overall survival on an intention-to treat basis was 33.1 months (3- and 5-year overall survival: 48.5% and 33.1%). Patients who were not able to complete their therapeutic paradigm had a significantly worse overall outcome (p = 0.03). CONCLUSION: The liver-first approach is feasible with acceptable perioperative morbidity and mortality rates. Despite the considerable overall-survival-benefit, recurrence rates remain high. Future research should focus on providing selection tools to enable the optimal treatment sequence for each patient with synchronous CRLM. PMID- 29456200 TI - Diagnostic validity of methods for assessment of swallowing sounds: a systematic review. AB - INTRODUCTION: Oropharyngeal dysphagia is a highly prevalent comorbidity in neurological patients and presents a serious health threat, which may lead to outcomes of aspiration pneumonia, ranging from hospitalization to death. This assessment proposes a non-invasive, acoustic-based method to differentiate between individuals with and without signals of penetration and aspiration. OBJECTIVE: This systematic review evaluated the diagnostic validity of different methods for assessment of swallowing sounds, when compared to videofluroscopy swallowing study to detect oropharyngeal dysphagia. METHODS: Articles in which the primary objective was to evaluate the accuracy of swallowing sounds were searched in five electronic databases with no language or time limitations. Accuracy measurements described in the studies were transformed to construct receiver operating characteristic curves and forest plots with the aid of Review Manager v. 5.2 (The Nordic Cochrane Centre, Copenhagen, Denmark). The methodology of the selected studies was evaluated using the Quality Assessment Tool for Diagnostic Accuracy Studies-2. RESULTS: The final electronic search revealed 554 records, however only 3 studies met the inclusion criteria. The accuracy values (area under the curve) were 0.94 for microphone, 0.80 for doppler, and 0.60 for stethoscope. CONCLUSION: Based on limited evidence and low methodological quality because few studies were included, with a small sample size, from all index testes found for this systematic review, doppler showed excellent diagnostic accuracy for the discrimination of swallowing sounds, whereas microphone-reported good accuracy discrimination of swallowing sounds of dysphagic patients and stethoscope showed best screening test. PMID- 29456201 TI - Modular radical cross-coupling with sulfones enables access to sp3-rich (fluoro)alkylated scaffolds. AB - Cross-coupling chemistry is widely applied to carbon-carbon bond formation in the synthesis of medicines, agrochemicals, and other functional materials. Recently, single-electron-induced variants of this reaction class have proven particularly useful in the formation of C(sp2)-C(sp3) linkages, although certain compound classes have remained a challenge. Here, we report the use of sulfones to activate the alkyl coupling partner in nickel-catalyzed radical cross-coupling with aryl zinc reagents. This method's tolerance of fluoroalkyl substituents proved particularly advantageous for the streamlined preparation of pharmaceutically oriented fluorinated scaffolds that previously required multiple steps, toxic reagents, and nonmodular retrosynthetic blueprints. Five specific sulfone reagents facilitate the rapid assembly of a vast set of compounds, many of which contain challenging fluorination patterns. PMID- 29456202 TI - Contrast-induced nephropathy: Pathophysiology, risk factors, and prevention. AB - Contrast-induced acute kidney injury is a common iatrogenic complication associated with increased health resource utilization and adverse outcomes, including short- and long-term mortality and accelerated progression of preexisting renal insufficiency. The incidence of contrast-induced nephropathy (CIN) has been reported to range from 0% to 24%. This wide range reported by the studies is due to differences in definition, background risk factors, type and dose of contrast medium used, and the frequency of other coexisting potential causes of acute renal failure. CIN is usually transient, with serum creatinine levels peaking at 2-3 days after administration of contrast medium and returning to baseline within 7-10 days after administration. Multiple studies have been conducted using variety of therapeutic interventions in an attempt to prevent CIN. Of these, careful selection of patients, using newer radiocontrast agents, maintenance of hydration status, and avoiding nephrotoxic agents pre- and post procedure are the most effective interventions to protect against CIN. This review focuses on the basic concepts of CIN and summarizes our recent understanding of its pathophysiology. In addition, this article provides practical recommendations with respect to CIN prevention and management. PMID- 29456203 TI - Effect of vitamin E on reversibility of renal function following discontinuation of colistin in rats: Histological and biochemical investigations. AB - This study was carried out to evaluate spontaneous renal regeneration after stopping colistin methanesulfonate (CMS), which induces tubular damage, and the curative effect of Vitamin E (vit E) in rats. Animals were given the following: sterile saline (n = 6), 300,000 IU/kg/ day of CMS (n = 24), or 450,000 IU/kg/day of CMS (n = 24) for seven days. Each CMS group was subdivided into four subgroups (n = 6) and sacrificed as follows: (i) 12 h after stopping CMS, (ii) two weeks after stopping CMS, (iii) two weeks after stopping treatment with vit E, and (iv) two weeks after stopping treatment with olive oil. Subsequently, plasma creatinine (pCr), urine N-acetyl-b-D-glucosaminidase (NAG), renal tissue level of malondialdehyde (MDA), superoxide dismutase (SOD), glutathione reductase (GSH), and renal histology were tested. CMS-induced tubular damage increased the NAG and MDA levels and decreased the SOD and GSH activities. After two weeks of stopping CMS, there was no significant renal recovery. However, treatment with vit E improved tubular regeneration and reduced the biochemical impairments. Two weeks might not be long enough for significant spontaneous renal regeneration. Improvement of renal parameters by vit E could be explained by the reduction of oxidative stress damage. PMID- 29456204 TI - Renoprotective effect of Nigella sativa against cisplatin-induced nephrotoxicity and oxidative stress in rat. AB - Cisplatin is one of the important antineoplastic drugs. Its clinical use has been restricted due to severe kidney toxicity. Nigella sativa (N. sativa) is an herbaceous plant with many pharmacologic effects. In the present study, we evaluated the protective effects of aqueous-ethanolic extract of N. sativa and Vitamin E on cisplatin-induced nephrotoxicity in rats. Eighty male rats were divided into eight groups: control, cisplatin (6 mg/kg; ip), preventive Vitamin E (100 mg/kg), preventive N. sativa (100,200 mg/kg), preventive + treatment Vitamin E, and preventive + treatment N. sativa (100, 200 mg/kg). Duration of this study was 11 days and cisplatin was injected on the 6th day of the experiment. Tissue damage in all groups that received N. sativa extract and Vitamin E showed a significant improvement compared with the cisplatin group. In addition, serum and tissue total thiol content in preventive and preventive + treatment N. sativa groups showed significant increase compared with cisplatin group. There was no significant difference in serum malondialdehyde concentration of the control rats compared with the preventive and preventive + treatment N. sativa groups. N. sativa extract and viamin E improved the pathology and oxidative stress in the rat kidney. However, more studies are needed to determine the mechanism of action of N. sativa on cisplatin-induced kidney toxicity. PMID- 29456205 TI - Mutational analysis of AGXT gene in Libyan children with primary hyperoxaluria type 1 at Tripoli Children Hospital. AB - Primary hyperoxaluria type 1 (PH1) is an inborn error of glyoxylate metabolism. It results from genetic mutation of the AGXT gene. The study objective was to verify the clinical and epidemiological patterns of PH1 in Libyan children at Tripoli Children Hospital confirmed by AGXT gene mutation. A descriptive case series study of 53 children with PH1 diagnosed between 1994 and 2015 was carried out in the Nephrology Unit at Tripoli Children Hospital. Diagnosis of PH1 was based on the clinical presentation (renal stones or nephrocalcinosis), positive family history of PH1, and high 24 h urinary oxalate. Sampling for AGXT gene mutation was collected from April 2012 to December. 2015. Among the 53 children included, males composed of 62.3% of patients. Their age at presentation ranged between two months and 20 years with a mean age of 55.4 +/- 48 months. The parents of 81.1% of these patients had positive consanguinity. Forty (75.5%) patients were from South West (mountain area), and 16 (40%) of them were from Yefrin. The most common mutation found in this study was c.731T>C (p.lle244thr) seen in 32 (71%) of children, and interestingly, among these patients, 87.1% were homozygous in gene typing, 86.2% had positive history of consanguinity, 71.4% were from South West (mountain area), 96.6% had family history of PH1, and 20% presented with impaired renal function. The patients with this mutation were younger at presentation than that with other genes, and it was more prevalent among boys (61.3%). Thus, the most common gene mutation found in Libyan children with PH1 was c.731T>C (p.lle244thr) and this is more likely due to the strong genetic pooling caused by the high consanguinity rate which requires an extensive genetic counseling. PMID- 29456206 TI - C4d-negative antibody-mediated rejection: A pathologist's perspective and clinical outcome. AB - Banff'13 update included C4d-antibody-mediated rejection (ABMR) as a separate entity responsible for graft dysfunction with limited clinical/prognostic implications. We present a retrospective study to determine the incidence and outcome of C4d-negative ABMR. A total of 987 renal allograft (RA) biopsies obtained from 987 RA recipients were studied from January 2013 to January 2016. All samples were subjected to light microscopy using standard stains and C4d immunohistochemistry on paraffin sections and reported according to modified Banff's criteria. Adequate biopsies with immunological injuries were categorized as Group 1: pure ABMR, Group 2: combined ABMR with concurrent T-cell-mediated rejection (TCR), and Group 3: pure TCR. Groups 1 and 2 were further subgrouped as C4d positive (Group 1a and 2a) or C4d negative (Group 1b and 2b). Graft function was measured by serum creatinine (SCr) level (mg/dL). Of the 987 biopsies, 43.3% (404) biopsies revealed immunological injury. Of these, 27.7% of the biopsies revealed pure ABMR (Group 1), 60.6% revealed combined ABMR with TCR (Group 2), and 11.3% revealed pure TCR (Group 3). The overall incidence of ABMR (pure ABMR + ABMR with TCR) was 36.27%, of which C4d-negative rejections were 18.48% and 18.7% in Group 1 and Group 2, respectively. The mean SCr at the end of three years follow-up in patients with C4d-negative rejections was comparatively higher. C4d negative ABMR, recently included in Banff'13, has a low incidence, usually presents early after transplantation but carries better outcome than C4d-positive ABMR. However, further long-term studies are still required for knowing the clinical course over years. PMID- 29456207 TI - Medical renal disease in tumor nephrectomies: The silent killer. AB - In tumor nephrectomy specimens, the evaluation of the normal renal parenchyma is often overlooked. A patient with both end-stage renal diseases (ESRDs) with a renal cell carcinoma is more likely to die of the ESRD rather than cancer. At the time of nephrectomy, a pathologist has a large amount of tissue available to him to comment upon the presence of disease in the nonneoplastic kidney. Hence, this study was undertaken with the idea of characterizing disease in the nonneoplastic kidney at the time of tumor nephrectomy. A two-year retrospective study was carried out on all tumor nephrectomies and partial nephrectomies. Glomerular, tubulointerstitial, and vascular compartments were evaluated for abnormalities. Twenty-four cases were included in the study. A total of 17 cases showed abnormalities in the nonneoplastic renal parenchyma. In the glomeruli, two cases showed IgA nephropathy, one case showed segmental sclerosis, and one case showed the presence of cellular crescents. A single case showed diabetic glomerulosclerosis. Interstitial fibrosis and tubular atrophy were noted in seven cases. Fifteen cases showed intimal sclerosis and medial hypertrophy and six cases showed nodular hyalinosis. Tumor nephrectomy specimens may very often show the presence of various nonneoplastic diseases. Hypertensive and diabetic renal disease are the major contributors, although primary glomerular diseases may also be present. At the time of the evaluation of a renal tumor on nephrectomy specimen, the status of the nonneoplastic kidney may become as an important predictor of clinical outcome as the tumor itself. PMID- 29456208 TI - Morbidity and mortality of hospitalized hip fractures in chronic hemodialysis. AB - Abnormal bone architecture contributes to high incidence of hip fractures in chronichemodialysis (HD) patients. Their clinical epidemiology is incompletely described. We conducted a retrospective cohort study to assess the implications ofhospitalization with hip fracture in HD patients compared to the nonchronic kidney disease population. Thirty-three chronic HD patients admitted with hip fracture overfiveyears were age- and sex-matched on a 1:1 ratio with controls that had hip fracture and normal renal function. Demographic characteristics, deaths, and readmissions atsixmonths,hospitalization length, time to operation, and laboratory resultswere recorded from electronic health files. Datawere compared betweenthe two groups usingpairedt-test for continuous variables and McNemar's test for categoricalvariables. The compositeendpoint of deathand/or readmission at6 months was higher in HD patients (12.1% vs. 6.2%, P<0.001). Furthermore, mean time tooperationwas more delayed due to comorbidities (4.7 vs. 2.9 days, p = 0.04). HD patients had anemia more frequently at presentation (hemoglobin below 10 mg/dL, 32.1% vs. 12.5%, P = 0.003). Finally, they were more likely to be considered toofrail for surgery and not be operated (21.2% vs. 6.2%, P<0.001). Hip fractures are associated with increased morbidity and mortality and represent an important health-care burden for chronic HD patients. Future research is needed to identify definite predictors of adverse outcomes and to implement prevention strategies. PMID- 29456209 TI - Assessment of prevalence and clinical outcome of frailty in an elderly predialysis cohort using simple tools. AB - The relationship between frailty and chronic kidney disease in elderly population has been recognized; however, studies concentrating on frailty in predialysis patients are limited. For nephrologists, the recognition of frailty is important as it has impact on decisions on the choice of dialysis modality and sometimes on whether dialysis is indeed in the patients' best interests. Many of the tools for routine assessment of frailty are not easily applicable to those clinicians not practicing elderly care medicine. A tool needs to be simple and applicable for daily routine practice. The aim of this study was to assess the prevalence and clinical outcome of frailty in an elderly predialysis population using simple tools. A nonrandomized prospective study was conducted in which, 104 patients aged 65 years or above with an estimated glomerular filtration rate of 25 mL or less were included. Data including age, sex, renal function, calcium, albumin, parathormone, and comorbidities were collected at baseline and at three months interval for one year. Functional performance was assessed using Karnofsky scale. The Charlson comorbidity index was used to assess comorbid status of each patient. Frailty was assessed using a combination of PRISMA questionnaire and Timed up and Go test. End points were death or start of dialysis at 20-month follow-up. A frail group (n = 58; males = 32, females = 26) and a nonfrail group (n = 46; males = 21, females = 25) were identified. Frailty was prevalent in 53.8% of the selected population. There was no significant difference between both groups in terms of age, gender, comorbidities, hemoglobin, inflammatory markers, or calcium hemostasis. Nine patients chose conservative management in the frail group and six in nonfrail group. Rate of death was significantly higher in the frail group (death = 14) compared to nonfrail group (death = 3; P = 0.01). There was no significant difference between both groups in terms of initiation of dialysis (P = 0.1). Frailty and Charlson comorbidity index were significantly associated with mortality (P = 0.023 and 0.032, respectively). Survival in frail patients who started peritoneal dialysis (PD) was slightly better than those started on hemodialysis (HD) with hazard ratio = 3.23 (P = 0.23). Our study shows that the prevalence of frailty and mortality rate is high among elderly predialysis patients. Frailty and Charlson comorbidity index are independent predictors of outcome in this population. PD might be a better option of dialysis modality compared to HD in the frail population. PMID- 29456210 TI - Appraising the outcome and complications of peritoneal dialysis patients in self care peritoneal dialysis and assisted peritoneal dialysis: A 5-year review of a single Saudi center. AB - Our objective is to study the outcomes and complications of peritoneal dialysis (PD) including comparison of self-care PD with home-care assisted PD during a five-year period. A retrospective study of PD data at King Saud University affiliated hospital in Riyadh from January 1, 2009, to December 31, 2013. One hundred and eleven patients were included (female 55%). The average age was 47.4 (1-83) years. Twenty-one (18.91%) patients were on continuous ambulatory PD and 90 (81.08%) on automated PD. The mean time on PD was 23.5 (3-60) months. At the end of five years, 47 (42.34%) patients were continuing on PD, 12 (10.81%) had renal transplant, 33 (29.73%) patients were transferred to hemodialysis, and two (1.8%) patients were transferred to other centers. Seventeen patients died during this period giving a mortality rate of 7.13 deaths/100 patient-year during the five-year period. Six patients died due to cardiovascular causes, while five had sepsis. There was one death each due to prostate cancer, hyperoxaluria, and toxic epidermal necrolysis. Three patients died suddenly at home. Peritonitis rate was one episode/35.28 patient/month or one episode/2.94 patient/year. We compared the results for patients doing the dialysis themselves [56 (50.45%)] "self-care PD" to 55 (49.5%) patients assisted by a family member or other caregivers "assisted PD." We found no significant difference in the incidence of complications, technical outcome, mortality, and peritonitis episodes. However, we found a high prevalence of diabetes mellitus and significant increase in exit site infection in assisted PD. Our study suggests that PD patients in Saudi Arabia have a good overall outcome. Furthermore, assisted PD showed good patient and technique outcome.

AB - Acute kidney injury (AKI) in the newborn is a common problem in the neonatal intensive care unit with many underlying factors such as asphyxia, respiratory distress syndrome (RDS), and urogenital anomalies. The aim of this study is to highlight possible risk factors and profile of neonates developing AKI in the Neonatal Intensive Care Unit (NICU) of Cairo University Pediatric Hospital. The study was carried out on 90 neonates (30 patients and 60 controls), among neonates admitted to NICU. The study was done over two months, from January 2015 to March 2015. Our study showed that sepsis was detected in 53.3%, prematurity in 46.67%, RDS in 43.3%, congenital heart disease in 20%, and hypoxic-ischemic encephalopathy in 6.67% of patients. Maternal illness and low body temperature were both significant risk factors of AKI in neonates. History of maternal illness, low body temperature, sepsis, prematurity, and respiratory distress can contribute to the development of AKI in neonates. PMID- 29456213 TI - Association of serum fibroblast growth factor-23 with Doppler pulse wave velocity in hemodialysis patients. AB - We aimed to study the association of fibroblast growth factor-23 (FGF-23) as a novel cardiovascular risk factor with Doppler pulse wave velocity (PWV) as an arterial stiffness measuring tool in hemodialysis (HD) patients. We conducted a cross-sectional study in which blood samples from 86 HD patients were obtained to estimate FGF 23 and other parameters. Flow waveforms were obtained at two locations within right common carotid artery, and right femoral artery by Doppler ultrasound with ECG recorded in addition. The time differences between the R wave of the ECG signal and the onset of the flow waveforms at the two sites yield DeltaT. Distances between sampling sites were measured using a tape measure. PWV was defined as (m/s) = D (m)/ DeltaT (s). In the current study, we found significant positive correlations between Doppler PWV and both age (r = 0.401, P = 0.039) and systolic blood pressure (r = 0.602, P = 0.034), while no significant association between Doppler PWV and FGF-23 (r = 0.123, P = 0.259) could be detected. Serum FGF-23 levels are not significantly associated with Doppler PWV in HD patients. PMID- 29456212 TI - The epidemiology of acute peritonitis in end-stage renal disease patients on peritoneal dialysis in Qatar: An 8-year follow-up study. AB - Acute peritonitis (AP) is a common and devastating complication in end-stage renal disease patients on peritoneal dialysis (PD). We are reporting an epidemiologic study of AP in Qatar over 8-year follow-up. We retrospectively reviewed medical records of all PD patients in Qatar from 2007 to 2014. The analysis was conducted to report epidemiology, outcome, and associated risk factors of AP. We had 318 AP episodes in 180 patients between 2007 and 2014. Six (3.3%) patients died as a result AP. Six cases of fungal peritonitis were reported. AP rate has decreased from 1 episode/29.7 PD-months in 2007 to 1/43.7 PD-months in 2014. Ninety-nine (55%) patients had single AP while 81 (45%) patients had 2 episodes or more (multiple AP). Patients on automated PD carried a higher risk of developing multiple AP [odds ratio (OR) = 1.46, 95% confidence interval (CI): 1.01-1.71]. The first episode of AP caused by Gram-positive cocci carried a significant risk of multiple AP (OR = 4.3, 95 % CI: 2.2-8.2). Negative culture AP carried a significant protective role from multiple AP (OR = 0.35, 95% CI: 0.19-0.66). Most deaths occurred with the first episode of AP (4 out of 6). In this 8-year follow-up, epidemiologic study from Qatar, fungal peritonitis and mortality rate were very low, AP rate improved overall, multiple AP was prevalent (45%), and its risk increases with Gram-positive cocci infections. Our results signify the importance of implementing more efficient care bundles to prevent multiple AP. PMID- 29456214 TI - Outcome of renal transplant recipients with cytomegalovirus and BK polyomavirus co-infection nephropathy. AB - Reactivation of cytomegalovirus (CMV) and BK polyomavirus (BKV) can result in virus-associated tubulointerstitial nephritis in renal allografts. All those renal biopsies reported as viral cytopathic were isolated and examined by two independent renal histopathologists from our institute and classified as CMV, BKV, and CMV-BKV coinfection-associated viral cytopathic changes with confirmation through polymerase chain reaction technology in either serum or urine or both. All twenty patients were categorized as 10 in CMV, four in BKV, and six were in CMV-BKV coinfection. One patient each had received antithymocyte globulin and basiliximab as induction all patients received triple-drug immunosuppression. The mean graft survival was 69, 61, and 59 months in CMV, BKV, and CMV-BKV coinfection group, respectively. At the end of the study period, 10 (50%) patients died. 1-, 3-and 5-year patient survival was 94%, 88% and 76% among CMV group, 75%, 75% and 50% in BKV group, and 96%, 83% and 62%, in CMV-BKV coinfection group (P = 0.157). CMV and BK virus are not so common infections in postrenal transplant patients yet an important cause of graft dysfunction. Coinfection did not pose an increased risk for acute rejection or patients and death-censored and uncensored graft survival among compared groups. PMID- 29456215 TI - Comparison of survival between dialysis patients with incident high-flux hemodialysis versus on-line hemodiafiltration: A single center experience in Saudi Arabia. AB - Conventional hemodialysis (HD) is the most common treatment modality used for renal replacement therapy. The concept of HD is based on the diffusion of solutes across a semipermeable membrane. Hemofiltration (HF) is based on convective transport of solutes; hemodiafiltration (HDF) is based on combined convective and diffusive therapies. Data about survival benefit of on-line HDF (OL-HDF) over high-flux HD (HF-HD) is conflicting. We conducted this study to investigate if there is a survival difference between the two treatment modalities. This study is a retrospective, single-center study in which 78 patients were screened; 18 were excluded and 60 patients were analyzed. The study patients were aged 47.5 +/ 20.7 years, 33 patients (55%) were on HF-HD, and 27 patients (45%) were on OL HDF. A total of 24 patients (40%) of both groups were diabetic and, the mean duration on dialysis was 43.5 +/-21.3 months in the HF-HD group and 41.2 +/- 22.0 months in the OL-HDF group. The mean substitution volume for OL-HDF was 22.3 +/- 2.5 L. Survival was 73% [95%, confidence interval (CI) 60-84] in the HF-HD group and 65% (95%, CI 54-75) in the OL-HDF group by the end of the study period. The unadjusted hazard ratio (HR) with 95% CI comparing HF-HD to high-volume postdilution OL-HDF was 0.78 (0.10-5.6; P = 0.810). Kaplan-Meier analysis for patient survival over five years showed no significant difference between the two modalities. Prospective controlled trials with a larger number of patients will be needed to assess the long-term clinical outcome of postdilution OL-HDF over HF HD. PMID- 29456216 TI - The cardiovascular risk factor profiles among end-stage renal failure patients treated with continuous ambulatory peritoneal dialysis and intermittent hemodialysis. AB - Cardiovascular (CV) event is the most common cause of death in dialysis patients. Both traditional and nontraditional CV risk factors related to malnutrition, inflammation, and anemia are commonly found in this population. This study was conducted to evaluate the burden factors of CV risk factors and its management in our regularly dialyzed patients. It was a single-center, cross-sectional analysis of prevalent intermittent hemodialysis (IHD) and continuous ambulatory peritoneal dialysis (CAPD) patients followed up in our hospital. Both the traditional and non-traditional CV risk factors were recorded and compared between the two groups. Eighty-eight patients were recruited. Forty-five were treated with CAPD and 43 patients were treated with IHD. The mean age was 49.5 +/- 15.17 years old and 54.5% were females. Eighty percent were Malay followed by Chinese (14.7%) and Indian (5.7%). Thirty-eight percent were hypertensive and 17% were diabetic. The mean age of CAPD patients was 48.9 +/- 16.9 compared to 50 +/- 13.5 years old for IHD patients (P > 0.05). The body mass index (BMI) of CAPD patients was 23.9 kg/m2 versus 21.7 kg/m2 of the IHD (P = 0.04). The systolic and diastolic blood pressure of CAPD patients were 158 and 89 mm Hg in comparison to 141 and 72 mm Hg in IHD patients (P <0.001) and their total and low-density lipoprotein cholesterol level were 5.93 mmol/L and 3.84 mmol/L versus 4.79 mmol/L and 2.52 mmol/L, respectively (P<=0.001). The CAPD patients were hyperglycemic more than IHD patients, although it was not statistically significant. All the nontraditional CV risk factors except serum albumin were comparable between the two groups. Serum albumin in CAPD patients was 35.5 g/L compared to 40.8 g/L in the IHD patients (P <0.001). In our prevalent dialysis-dependent patients, both traditional and non-traditional CV risk factors are common. Due to the prolonged and continuous glucose exposure from the peritoneal dialysis fluid, the CAPD patients had highly atherogenic serum, higher BMI, and intensified inflammation which pre-disposed them to higher CV events. PMID- 29456217 TI - Vascular access mortality and hospitalization among hemodialysis patients in Palestine. AB - Vascular access complications are common in patients with end-stage kidney disease who are receiving maintenance hemodialysis (HD) and are responsible for an enormous burden of morbidity and mortality among these patients. Differences in the all-cause mortality rate and hospitalization between dialysis catheter use and arteriovenous (AV) vascular access use have not been documented in our HD population. We performed a 12-month prospective analysis of our HD patients from four dialysis centers. We examined all-cause mortality and hospitalization in patients being dialyzed through HD catheters as compared to patients with AV access. A total of 382 patients were included in the study. Of these, 88 had catheters and 294 had AV accesses. Seventy-eight percent of all catheters were temporary nontunneled dialysis catheters. The overall gross mortality rate for all patients was 14.7%. Gross mortality was significantly lower among AV access group compared to the catheter group (12.2% vs. 22.7%; P = 0.015). Catheter use was associated with a relative hazard ratio (HR) of 1.85 [95% confidence interval (CI), 1.13-3.03] compared with use of an AV access. Hospitalization rate was also significantly lower among patients with AV access versus patients who used catheters (27.6% vs. 46.6%; P = 0.006). The risk of hospitalization was also higher in catheter users with a relative HR of 1.69 (95% CI, 1.26-2.26) compared with use of AV access. In our HD population where the majority of catheters were temporary nontunneled catheters, dialysis catheter use was associated with higher mortality and increased hospitalization rates compared with AV access. These results emphasize the urgent need to minimize the use of dialysis catheters, in order to reduce mortality and hospitalization rates among HD patients. PMID- 29456218 TI - Renal anemia syndromes in iraqi hemodialysis patients according to iron status. AB - Anemia is common in patients on hemodialysis (HD). Adequate iron stores are essential for achieving the best hemoglobin level through maximum benefit from erythropoiesis-stimulating agents (ESA). Decreased iron stores or decreased availability of iron are the most common reasons for resistance to the effect of these agents. Our objective was to categorize a group of Iraqi HD patients according to absolute or functional iron deficiency anemia (IDA); this study was conducted in the HD unit of the Baghdad Teaching Hospital from October 2012 to January 2013. Seventy prevalent adult HD Iraqi patients were enrolled. All patients were tested for full blood counts and iron parameters. They were categorized as nonanemic and those with absolute or functional iron deficiency. The patients were also tested for serum albumin, C-reactive protein (CRP), parathyroid hormone, and serum hepcidin levels. Data were expressed as mean +/- standard deviation, and frequencies (number) and proportions (%). The mean age of the study group was 49.8 +/- 12.3 years. Diabetes was the primary cause of end stage renal disease, seen in 30 patients (42.8%). Majority of the HD patients were anemic, [51 (82.9%)] and among them, 39 (76.4%), had functional IDA. The mean serum iron, serum ferritin, and transferrin saturation were significantly higher in patients with functional IDA than those with absolute IDA (P <0.05). The mean highly sensitive CRP, parathormone and hepcidin values were also significantly higher in functional IDA patients than in those with absolute IDA and the nonanemic group (P <0.05). More than half of the study patients had functional IDA, and this can explain ESA hyporesponsiveness. This is besides the interplay of other factors including inflammation, inadequate dialysis, and secondary hyperparathyroidism. It is essential to diagnose functional IDA early, before the initiation of unnecessary iron therapy. PMID- 29456219 TI - Descriptive analysis of glomerulonephritis by histological type and their progression among adults in a tertiary care center in Sri Lanka. AB - Prevalence of different glomerulonephritides and their clinical course vary geographically. Our objectives are to assess the prevalence of different histological types of glomerulonephritis (GN) based on the light microscopic histology and to assess their progression according to histological type. A retrospective cross-sectional study was carried out among adult patients (>18 years) with a histological diagnosis of GN at the University Professorial Unit over a period of six months. Information including demographic data, renal biopsy findings, and progression of the disease through serum creatinine (SCr) level were collected through existing clinic records of consenting patients. Data were analyzed by Statistical Package for the Social Sciences. There were 109 patients (females = 90) with a mean age of 40.32 +/- 15.24 years. The most common histological type was focal segmental glomerulosclerosis (FSGS) in 27 (24.8%) followed by minimal change disease in 25 (22.9%), mesangioproliferative glomerulonephritis (MesPGN) in 18 (16.5%), membranoproliferative glomerulonephritis in six (5.5%), membranous glomerulonephritis in three patients (2.8%), and crescentic GN in one patient (0.9%). There was a statistically significant rise in SCr level at seven years from the initial presentation in the histological types; FSGS [P = 0.04; 95% confidence interval (CI) = 0.06-1.0] and MesPGN (P = 0.03; 95% CI = 0.3-0.9). Focal segmental glomerulosclerosis was the most common histology type in the population studied. There was a statistically significant progression of FSGS and MesPGN. PMID- 29456220 TI - Importance of renal biopsy in patients aged 60 years and older: Experience from a tertiary care hospital. AB - As the life expectancy is increasing, there is a rise in elderly population and consequent increase in the patients with renal disease. There is an inconsistency between clinical and histopathological diagnosis in elderly, and so renal biopsy is important in these patients to decide appropriate clinical management and prognosis. This study outlines the importance of renal biopsy in elderly and describes the clinical and pathologic spectrum of renal diseases in patient >=60 years. All patients (age >=60 years) undergoing renal biopsies from January 2011 to December 2014 were included in this retrospective study. The clinical presentation and biochemical findings were recorded, and the patients were grouped based on their clinical presentation. Renal biopsies were also evaluated. The mean age of patients was 67.7 +/- 6.4 years with a male:female ratio of 3:1. The most common clinical manifestation was nephrotic syndrome (37.4%) followed by rapidly progressive renal failure (RPRF) (20.6%). Amyloidosis and membranous nephropathy were two most common diagnoses in patients with nephrotic presentation whereas pauci-immune crescentic glomerulonephritis and cast nephropathy were common in patients presenting with RPRF. Clinical diagnosis differed from the histopathological diagnosis in 32% cases of nephrotic syndrome. There was good agreement between clinical diagnosis and histology in cases with RPRF. In 73% cases of elderly with (Type II) diabetes suspected of having nondiabetic renal disease clinically, renal biopsy showed evidence of diabetic nephropathy. Renal biopsy is essential in the diagnosis of renal diseases even in elderly. Amyloidosis and membranous nephropathy are common causes of nephrotic syndrome in elderly. Renal biopsy is very useful in diagnosing cast nephropathy and amyloidosis as they are not suspected clinically. It is also helpful in elderly diabetics without retinopathy to differentiate between diabetic and nondiabetic kidney diseases. PMID- 29456221 TI - Comparison between brief food frequency questionnaire and food record to assess the energy and protein intake of hemodialysis patients at Dr. Sardjito Hospital in Indonesia. AB - Dietary assessment is absolutely necessary to meet the dietary requirements of hemodialysis (HD) patients. A food record is the most commonly used method; however, it is not routinely performed. The weakness of this method is that it is burdensome for some respondents and requires more time to complete data entry. Meanwhile, the brief food frequency questionnaire (BFFQ) is a quicker and simpler method to assess individual dietary intake. We aimed to compare the BFFQ and food records as assessment methods of energy and protein intake for HD patient in Dr. Sardjito Hospital in Indonesia. This study was conducted on March to April 2015 in HD Unit of Dr. Sardjito Hospital, Indonesia, as an observational study. This was a cross-sectional study. Data were collected from 103 patients, who were selected using a purposive sampling method. All participants' dietary intakes were assessed using a food record and the BFFQ to obtain total protein and energy intakes. Wilcoxon test was used for the statistical analysis. There was a significant difference (P <0.0001) between the methods used to assess energy intake in HD patients at Dr. Sardjito Hospital. However, there was no significant difference (P = 0.732) between the two methods used to assess protein intake among patients. This difference was caused by a missing list in the BFFQ about snacks that were usually consumed by patients as energy sources. The BFFQ can be used as a protein intake assessment tool in HD patients. However, the BFFQ is not suitable to assess energy intake in patients. PMID- 29456222 TI - Prevalence and risk factors of chronic kidney disease in Cote D'Ivoire: An analytic study conducted in the department of internal medicine. AB - Chronic kidney disease (CKD) has become a public health problem because of its increasing prevalence. The objective of this study was to describe the current profile of CKD in our working conditions. This is a descriptive retrospective study of patients admitted for CKD during the period from January 2010 to December 2014 in the Internal Medicine Department of the university hospital of Treichville in Abidjan. CKD was defined by a glomerular filtration rate below 60 mL/min lasting for at least three months. We collected 252 cases of CKD out of 3573 patients recorded during the study period, yielding a prevalence of 7%. The mean age was 39.6 +/- 14 years (15-83 years). We observed a male predominance (sex ratio 1.2:1). Of the CKD patients studied, 67.1% were hypertensive, 7.9% were diabetic, and 8.7% were positive for human immunodeficiency (HIV) virus. The CKD was Stage 3 in 2.4%, Stage 4 in 3.2%, and Stage 5 in 94.4% of the patients. The etiology of CKD was hypertension in 59.9% of cases, followed by chronic glomerulonephritis (25%), HIV infection (9.1%), and diabetes (4.8%). On bivariate analysis, hypertension was the cause of CKD in 48.8% of patients under 35 years, 66.4% in patients between 35 and 64 years, and 85.4% in patients >=65 years (P = 0.001). Chronic glomerulonephritis was the cause of CKD in 40.2% of patients under 35 years, in 14.3% between 35 and 64 years, and in 4.8% of patients >=65 years (P = 0.0001). CKD is a common cause of hospitalization in our department. Patients generally consulted at the late stage of the disease. Risk factors are mainly hypertension, HIV infection, and diabetes. PMID- 29456223 TI - Knowledge and attitude toward organ donation among people in Lanja: A rural town in India. AB - Organ shortage is the greatest challenge facing the field of organ transplantation today. We aimed to study the attitude and knowledge toward body and organ donation among people in rural India. The present study was conducted in a rural town called Lanja, in the Konkan region of Maharashtra in India. A questionnaire covering demographic data, knowledge, and attitude of the participants was distributed to 400 students, middle-aged and senior citizens; 91.5% of the respondents were aware about organ donation. Television (55.2%) and newspaper (45.8%) were the most popular sources of information. About 56.2% and 32.8% believed that a healthy person and a cardiac dead person can be donors, respectively. Nearly 29.4% believed that a brain-dead person can be a donor and 22.4% clearly stated as to be having no idea regarding the health status of a donor. Highest awareness was observed regarding eye donation (92%). High awareness was also observed regarding heart, kidney, and liver donations, that is, 71.1%, 61.2%, and 54.2%, respectively. Awareness regarding donation of other tissues and organs was poor. Only 46.8% believed that the family of the deceased person can give consent for organ donation if the donor had not signed the donor card. Awareness regarding both body and organ donation in rural India is high. However, there is lack of understanding regarding the concept of brain-death. Awareness regarding body and other organ and tissue donations besides eye, kidney, etc., needs further awareness drives. PMID- 29456224 TI - Alport's syndrome with focal segmental glomerulosclerosis lesion - Pattern to recognize. AB - The association between Alport's syndrome (AS) and focal segmental glomerulosclerosis (FSGS) in the same patient is complex and rarely reported. We report a case of a 42-year-old male presenting with proteinuria, microscopic hematuria, elevated serum creatinine and hypertension with unremarkable physical examination apart from obesity. The renal biopsy showed well-established FSGS pattern of injury with mild interstitial fibrosis and tubular atrophy, while the electron microscopic examination demonstrated glomerular basement membranes (GBM) changes compatible with AS. AS can be complicated by segmental glomerular scarring, which can mimic primary FSGS, while familial FSGS can result from mutations in collagen IV network of the GBM. This overlap can complicate histopathological interpretation of renal biopsy, which should be accompanied by mutational analysis for accurate diagnosis and proper therapeutic intervention.

This was managed successfully by graft nephrectomy and interposition polytetrafluoroethylene grafting of the CIA and EIA with re-implantation of the kidney allograft and restoration of its perfusion and function, together with restoration of the lower limb circulation. PMID- 29456226 TI - Three cases of prune belly syndrome at the Lagos State University Teaching Hospital, Ikeja. AB - Prune belly syndrome (PBS) is a rare congenital disorder affecting 2.5 to 3.8/100,000 live births worldwide. Our objective of this report is to describe clinical manifestation, laboratory, and radiological characteristics of PBS in our patients, to highlight the limitations to offering appropriate patient care due to parents demanding discharge against medical advice and the need to increase the awareness regarding this rare disease. We report three cases; all referred after birth with lax abdominal wall, congenital anomalies of kidney, and urinary tract. One of the patients had an absent right foot. They all had cryptorchidism, and in one, there was deranged renal function. The reported cases had both medical and radiological interventions to varying degrees. They all had an abdominal ultrasound which revealed varying degrees of hydronephrosis, hydroureters, and bladder changes. Voiding cystourethrogram showed vesicoureteric reflux in one of the reported cases. Urinary tract infections were appropriately treated with antibiotics based on sensitivity. PBS management in our setting remains a challenge because of strong cultural beliefs, and high rate of discharge against medical advice. Focus should be on parent education, early diagnosis, and multidisciplinary management approach. PMID- 29456227 TI - A case of renal granulomatosis with polyangiitis following intravesical bacillus Calmette-Guerin therapy. AB - Various adverse reactions may occur after intravesical bacillus Calmette-Guerin (BCG) therapy. Although the virulence of attenuated BCG is low, serious complications such as bacterial cystitis, bladder contractures, granulomatous prostatitis, epididymitis, orchitis, and systemic reactions such as fever and malaise have been described. Disseminated granulomatosis such as hepatitis and pneumonitis have also been described, but are rare. We report here the case of a 67-year-old patient who presented with renal granulomatosis with polyangiitis following intravesical BCG therapy for superficial bladder tumor. The biological evaluation revealed the presence of perinuclear anti-neutrophil cytoplasmic antibodies with specificity for antimyeloperoxidase. Renal biopsy specimen revealed pauci-immune crescentic glomerulonephritis with segmental glomerular necrosis, presence of granulomas and no evidence of any caseating necrosis. He received antituberculosis drugs in addition to corticosteroids and cyclophosphamide without any improvement of the renal function.

We report two cases of young males with flank pain, renal mass, and hypertension with history of blunt abdominal trauma. Initially, hypertension was controlled by angiotensin-converting enzyme (ACE) inhibitors but gradually became refractory to medical treatment. Laparoscopic nephrectomy was performed in both patients. We emphasize the Page kidney as a cause of hypertension in young patients, presenting with flank pain and renal mass with or without complications of hypertension. Management is aimed to control blood pressure by ACE inhibitors, aspiration of the hematoma, open hematoma evacuation, or nephrectomy.

AB - Choreoathetotic syndrome is a rare complication of open cardiac surgery that is seen usually in children after surgery for congenital cardiac anomalies. Here, we report two cases of adult patients with end-stage renal disease (ESRD) on regular hemodialysis who developed acute choreoathetotic syndrome few days after cardiac surgeries under cardiopulmonary bypass (CPB). Improvement was seen after an interval with complete resolution in one case. Investigations of the cause have been noncontributory. Long CPB time seems to be the main identified risk factor in these cases. One of the unusual features of our adult cases was the existence of ESRD. To the best of our knowledge, this is the first time this complication is described in association with ESRD although the role of this comorbidity in these cases is uncertain.

Symptomatic congenital CMV infection involves multiple systems and causes significant morbidity and mortality in newborns. Isolated CMV infection of the kidneys in a living infant has not been reported in literature. Here, we report an infant who presented only with renomegaly and renal biopsy showed extensive CMV inclusions. Serum and urine polymerase chain reaction for CMV were positive, and CMV involvement of other organs was ruled out. The child for treated with intravenous ganciclovir and is currently on follow-up. Cytomegalic inclusion disease involving only kidneys without other systems involvement can occur. The treatment protocol is unclear and long-term follow-up is needed.

AB - BACKGROUND The aim of this study was to evaluate the role of remote ischemic postconditioning (RIPC) of the upper arm on protection from cardiac ischemia reperfusion injury following primary percutaneous coronary intervention (PCI) in patients with acute ST-segment elevation myocardial infarction (STEMI). MATERIAL AND METHODS Eighty patients with STEMI were randomized into two groups: primary PCI (N=44) and primary PCI+RIPC (N=36). RIPC consisted of four cycles of 5 minutes of occlusion and five minutes of reperfusion by cuff inflation and deflation of the upper arm, commencing within one minute of the first PCI balloon dilatation. Peripheral venous blood samples were collected before PCI and at 0.5, 8, 24, 48, and 72 hours after PCI. Levels of creatine kinase-MB (CK-MB), serum creatinine (Cr), nitric oxide (NO), and stromal cell-derived factor-1alpha (SDF 1alpha) were measured. The rates of acute kidney injury (AKI) and the estimated glomerular filtration rate (eGFR) were calculated. RESULTS Patients in the primary PCI+RIPC group, compared with the primary PCI group, had significantly lower peak CK-MB concentrations (P<0.01), a significantly increased left ventricular ejection fraction (LVEF) (P=0.01), a significantly lower rate of AKI (P<0.01) a significantly increased eGFR (P<0.01), and decreased area under the curve (AUC) of CK-MB, NO and SDF-1alpha. CONCLUSIONS RIPC of the upper arm following primary PCI in patients with acute STEMI might provide cardiac and renal protection from ischemia-reperfusion injury via the actions of SDF-1alpha, and NO.

AB - BACKGROUND Cryptococcal meningitis in patients who are seronegative for the human immunodeficiency virus (HIV) and in patients who are splenectomized is rare. This report is an unusual case of meningeal and cerebellar infection due to the encapsulated yeast, Cryptococcus neoformans, which has not previously been associated with asplenia. CASE REPORT A 65-year-old HIV-negative patient with a previous splenectomy, presented with a three-day history of fever, vomiting, and headache. His symptoms progressed to generalized body aches, persistent fever, and neck stiffness. A lumbar puncture was performed, and cerebrospinal fluid (CSF) culture grew Cryptococcus neoformans. Treatment commenced with intravenous amphotericin B and flucytosine. The patient required serial lumbar punctures due to persistent raised intracranial pressure (ICP). Magnetic resonance imaging (MRI) of the brain showed acute meningitis and cerebellitis. Antimicrobial therapy and CSF drainage resulted in clinical improvement. CONCLUSIONS The occurrence of meningeal and cerebellar cryptococcosis in an asplenic patient is rare, and few cases have been previously reported. This case report highlights the possibility of invasive cryptococcal infection, or cryptococcosis, in asplenic individuals in the absence of HIV infection.

AB - Signal transducer and activator of transcription 3 (STAT3) is constitutively activated in malignant tumors and plays important roles in multiple aspects of cancer aggressiveness. Thus, targeting STAT3 promises to be an attractive strategy for the treatment of advanced metastatic tumors. Bisindolylmaleimide alkaloid (BMA) has been shown to have anti-cancer activities and was thought to suppress tumor cell growth by inhibiting protein kinase C. In this study, we show that a newly synthesized BMA analog, BMA097, is effective in suppressing tumor cell and xenograft growth and in inducing spontaneous apoptosis. We also provide evidence that BMA097 binds directly to the SH2 domain of STAT3 and inhibits STAT3 phosphorylation and activation, leading to reduced expression of STAT3 downstream target genes. Structure activity relationship analysis revealed that the hydroxymethyl group in the 2,5-dihydropyrrole-2,5-dione prohibits STAT3 inhibitory activity of BMA analogs. Altogether, we conclude that the synthetic BMA analogs may be developed as anti-cancer drugs by targeting and binding to the SH2 domain of STAT3 and inhibiting the STAT3 signaling pathway.

AB - Tuberculosis (TB) is the number one cause of human death due to an infectious disease. The causative agents of TB are a group of closely related bacteria known as the Mycobacterium tuberculosis complex (MTBC). As the MTBC exhibits a clonal population structure with low DNA sequence diversity, methods (such as multilocus sequence typing) that are applied to more genetically diverse bacteria are uninformative, and much of the ecology and evolution of the MTBC has therefore remained unknown. Owing to recent advances in whole-genome sequencing and analyses of large collections of MTBC clinical isolates from around the world, many new insights have been gained, including a better understanding of the origin of the MTBC as an obligate pathogen and its molecular evolution and population genetic characteristics both within and between hosts, as well as many aspects related to antibiotic resistance. The purpose of this Review is to summarize these recent discoveries and discuss their relevance for developing better tools and strategies to control TB.

AB - Lipid research represents a frontier for microbiology, as showcased by hopanoid lipids. Hopanoids, which resemble sterols and are found in the membranes of diverse bacteria, have left an extensive molecular fossil record. They were first discovered by petroleum geologists. Today, hopanoid-producing bacteria remain abundant in various ecosystems, such as the rhizosphere. Recently, great progress has been made in our understanding of hopanoid biosynthesis, facilitated in part by technical advances in lipid identification and quantification. A variety of genetically tractable, hopanoid-producing bacteria have been cultured, and tools to manipulate hopanoid biosynthesis and detect hopanoids are improving. However, we still have much to learn regarding how hopanoid production is regulated, how hopanoids act biophysically and biochemically, and how their production affects bacterial interactions with other organisms, such as plants. The study of hopanoids thus offers rich opportunities for discovery. PMID- 29456245 TI - Animal models of monoclonal immunoglobulin-related renal diseases. AB - The renal deposition of monoclonal immunoglobulins can cause severe renal complications in patients with B cell and plasma cell lymphoproliferative disorders. The overproduction of a structurally unique immunoglobulin can contribute to the abnormal propensity of monoclonal immunoglobulins to aggregate and deposit in specific organs. A wide range of renal diseases can occur in multiple myeloma or monoclonal gammopathy of renal significance, including tubular and glomerular disorders with organized or unorganized immunoglobulin deposits. The development of reliable experimental models is challenging owing to the inherent variability of immunoglobulins and the heterogeneity of the pathologies they produce. However, although imperfect, animal models are invaluable tools to understand the molecular pathogenesis of these diseases, and advances in creating genetically modified animals might provide novel approaches to evaluate innovative therapeutic interventions. We discuss the strategies employed to reproduce human monoclonal immunoglobulin-induced kidney lesions in animal models, and we highlight their advantages and shortcomings. We also discuss how these models have affected the management of these deposition diseases and might do so in the future. Finally, we discuss hypotheses that explain some limitations of the various models, and how these models might improve our understanding of other nephropathies without immunoglobulin involvement that have similar pathogenic mechanisms.

PMID- 29456247 TI - B cells are the predominant mediators of early systemic viral dissemination during rectal LCMV infection. AB - Determining the magnitude of local immune response during mucosal exposure to viral pathogens is critical to understanding the mechanism of viral pathogenesis. We previously showed that vaginal inoculation of lymphocytic choriomeningitis virus (LCMV) fails to induce a robust innate immune response in the lower female reproductive tract (FRT), allowing high titer viral replication and a delay in T cell-mediated viral control. Despite this immunological delay, LCMV replication remained confined mainly to the FRT and the draining iliac lymph node. Here, we show that rectal infection with LCMV triggers type I/III interferon responses, followed by innate immune activation and lymphocyte recruitment to the colon. In contrast to vaginal exposure, innate immunity controls LCMV replication in the colon, but virus rapidly disseminates systemically. Virus-induced inflammation promotes the recruitment of LCMV target cells to the colon followed by splenic viral dissemination by infected B cells, and to a lesser extent by CD8 T cells. These findings demonstrate major immunological differences between vaginal and rectal exposure to the same viral pathogen, highlighting unique risks associated with each of these common routes of sexual viral transmission.

AB - Although several factors are known to play a role in the development and progression of glaucoma, intraocular pressure (IOP) remains the only modifiable risk factor. Medical and surgical treatments for glaucoma both aim to reduce IOP to minimize disease progression. Tonometry is therefore an essential element of the ophthalmological exam. There are several types of tonometers available currently. These range from well-established instruments that have been in clinical use for decades to new devices, which are the result of recent technological advances. The various instruments have advantages and disadvantages that affect their suitability for a given setting, purpose, and patient population. In this review, we aim to describe the most commonly available tonometers today along with their advantages, disadvantages, and applicability. PMID- 29456246 TI - Mitochondrial dysfunction in diabetic kidney disease. AB - Globally, diabetes is the leading cause of chronic kidney disease and end-stage renal disease, which are major risk factors for cardiovascular disease and death. Despite this burden, the factors that precipitate the development and progression of diabetic kidney disease (DKD) remain to be fully elucidated. Mitochondrial dysfunction is associated with kidney disease in nondiabetic contexts, and increasing evidence suggests that dysfunctional renal mitochondria are pathological mediators of DKD. These complex organelles have a broad range of functions, including the generation of ATP. The kidneys are mitochondrially rich, highly metabolic organs that require vast amounts of ATP for their normal function. The delivery of metabolic substrates for ATP production, such as fatty acids and oxygen, is altered by diabetes. Changes in metabolic fuel sources in diabetes to meet ATP demands result in increased oxygen consumption, which contributes to renal hypoxia. Inherited factors including mutations in genes that impact mitochondrial function and/or substrate delivery may also be important risk factors for DKD. Hence, we postulate that the diabetic milieu and inherited factors that underlie abnormalities in mitochondrial function synergistically drive the development and progression of DKD. PMID- 29456252 TI - Normal tension glaucoma: review of current understanding and mechanisms of the pathogenesis. AB - Normal tension glaucoma (NTG) is an exception in the "glaucoma family" where the major risk factor, increased intraocular pressure, is missing. If not increased intraocular pressure, then what other causes can then lead to glaucomatous optic disc change and visual field loss in NTG? Several possibilities will be discussed. Among them a higher sensitivity to normal pressure, vascular dysregulation, an abnormally high translaminar pressure gradient and a neurodegenerative process due to impaired cerebrospinal fluid dynamics in the optic nerve sheath compartment. There are many excellent review papers published on normal tension glaucoma (NTG). The aim of this paper is therefore not to add another extensive review on NTG but rather to focus on and to discuss some possible mechanisms that are thought to be involved in the pathophysiology of NTG and to discuss the stronger and weaker aspects of each concept. The fact that several concepts exist suggests that NTG is still not very well understood and that no single mechanism on its own might adequately explain NTG. PMID- 29456254 TI - Far Ultraviolet Spectroscopy of Old Novae. II. RR Pic, V533 Her, and DI Lac. AB - The old novae V533 Her (Nova Her 1963), DI Lac (Nova Lac 1910), and RR Pic (Nova Pic 1891) are in (or near) their quiescent stage, following their nova explosions, and continue to accrete at a high rate in the aftermath of their explosions. They exhibit continua that are steeply rising into the FUV, as well as absorption lines and emission lines of uncertain origin. All three have Far Ultraviolet Spectroscopic Explorer (FUSE) spectra that offer not only higher spectral resolution but also wavelength coverage extending down to the Lyman Limit. For DI Lac, we have matched these FUSE spectra with existing archival International Ultraviolet Explorer spectral coverage to broaden the FUV wavelength coverage. We adopted the newly determined interstellar reddening corrections of Selvelli & Gilmozzi. The dereddened FUV spectra have been modeled with our grids of optically thick accretion disks and hot, NLTE white dwarf (WD) photospheres. The results of our modeling analysis indicate that the hot components in RR Pic and V533 Her are likely to be accretion disks with mass accretion rates of 10-8M? yr-1 and 10-9M? yr-1 respectively. However, the disk cannot produce the observed absorption lines. For the WD to be the source of the absorption lines in these two systems, it must be very hot, with a radius several times its expected size (because the WD in these systems is massive, it has a smaller radius). For DI Lac, we find the best fit to be a disk with M = 10-10M? yr-1 with a 30,000 K WD. PMID- 29456255 TI - FUSE Spectroscopy of the Accreting Hot Components in Symbiotic Variables. AB - We have conducted a spectroscopic analysis of the far ultraviolet archival spectra of four symbiotic variables, EG And, AE Ara, CQ Dra and RW Hya. RW Hya and EG And have never had a recorded outburst while CQ Dra and AE Ara have outburst histories. We analyze these systems while they are in quiescence in order to help reveal the physical properties of their hot components via comparisons of the observations with optically thick accretion disk models and NLTE model white dwarf photospheres. We have extended the wavelength coverage down to the Lyman Limit with FUSE spectra. We find that the hot component in RW Hya is a low mass white dwarf with a surface temperature of 160,000K. We re examine whether or not the symbiotic system CQ Dra is a triple system with a red giant transferring matter to a hot component made up of a cataclysmic variable in which the white dwarf has a surface temperature as low as ~20,000K. The very small size of the hot component contributing to the shortest wavelengths of the FUSE spectrum of CQ Dra agrees with an optically thick and geometrically thin (~4% of the WD surface) hot (~ 120, 000K) boundary layer. Our analysis of EG And reveals that its hot component is a hot, bare, low mass white dwarf with a surface temperature of 80-95,000K, with a surface gravity log(g) = 7.5. For AE Ara, we also find that a low gravity (log(g) ~ 6) hot (T ~ 130, 000K) WD accounts for the hot component. PMID- 29456253 TI - Delicate regulation of the cGAS-MITA-mediated innate immune response. AB - Although it has long been demonstrated that cytosolic DNA is a potent immune stimulant, it is only in recent years that the molecular mechanisms of DNA stimulated innate immune responses have emerged. Studies have established critical roles for the DNA sensor cyclic GMP-AMP synthase (cGAS) and the adapter protein MITA/STING in the innate immune response to cytosolic DNA or DNA viruses. Although the regulation of cGAS-MITA/STING-mediated signaling remains to be fully investigated, understanding the processes involved may help to explain the mechanisms of innate immune signaling events and perhaps autoinflammatory diseases and to provide potential therapeutic targets for drug intervention. In this review, we summarize recent progress on the regulation of the cGAS MITA/STING-mediated innate immune response to DNA viruses at the organelle trafficking, post-translational and transcriptional levels. PMID- 29456256 TI - Clustering the Orion B giant molecular cloud based on its molecular emission. AB - Context: Previous attempts at segmenting molecular line maps of molecular clouds have focused on using position-position-velocity data cubes of a single molecular line to separate the spatial components of the cloud. In contrast, wide field spectral imaging over a large spectral bandwidth in the (sub)mm domain now allows one to combine multiple molecular tracers to understand the different physical and chemical phases that constitute giant molecular clouds (GMCs). Aims: We aim at using multiple tracers (sensitive to different physical processes and conditions) to segment a molecular cloud into physically/chemically similar regions (rather than spatially connected components), thus disentangling the different physical/chemical phases present in the cloud. Methods: We use a machine learning clustering method, namely the Meanshift algorithm, to cluster pixels with similar molecular emission, ignoring spatial information. Clusters are defined around each maximum of the multidimensional Probability Density Function (PDF) of the line integrated intensities. Simple radiative transfer models were used to interpret the astrophysical information uncovered by the clustering analysis. Results: A clustering analysis based only on the J = 1 - 0 lines of three isotopologues of CO proves suffcient to reveal distinct density/column density regimes (nH ~ 100 cm-3, ~ 500 cm-3, and > 1000 cm-3), closely related to the usual definitions of diffuse, translucent and high-column density regions. Adding two UV-sensitive tracers, the J = 1 - 0 line of HCO+ and the N = 1 - 0 line of CN, allows us to distinguish two clearly distinct chemical regimes, characteristic of UV-illuminated and UV-shielded gas. The UV-illuminated regime shows overbright HCO+ and CN emission, which we relate to a photochemical enrichment effect. We also find a tail of high CN/HCO+ intensity ratio in UV illuminated regions. Finer distinctions in density classes (nH ~ 7 * 103 cm-3 ~ 4 * 104 cm-3) for the densest regions are also identified, likely related to the higher critical density of the CN and HCO+ (1 - 0) lines. These distinctions are only possible because the high-density regions are spatially resolved. Conclusions: Molecules are versatile tracers of GMCs because their line intensities bear the signature of the physics and chemistry at play in the gas. The association of simultaneous multi-line, wide-field mapping and powerful machine learning methods such as the Meanshift clustering algorithm reveals how to decode the complex information available in these molecular tracers. PMID- 29456257 TI - IRC +10 216 in 3-D: morphology of a TP-AGB star envelope. AB - During their late pulsating phase, AGB stars expel most of their mass in the form of massive dusty envelopes, an event that largely controls the composition of interstellar matter. The envelopes, however, are distant and opaque to visible and NIR radiation: their structure remains poorly known and the mass-loss process poorly understood. Millimeter-wave interferometry, which combines the advantages of longer wavelength, high angular resolution and very high spectral resolution is the optimal investigative tool for this purpose. Mm waves pass through dust with almost no attenuation. Their spectrum is rich in molecular lines and hosts the fundamental lines of the ubiquitous CO molecule, allowing a tomographic reconstruction of the envelope structure. The circumstellar envelope IRC +10 216 and its central star, the C-rich TP-AGB star closest to the Sun, are the best objects for such an investigation. Two years ago, we reported the first detailed study of the CO(2-1) line emission in that envelope, made with the IRAM 30-m telescope. It revealed a series of dense gas shells, expanding at a uniform radial velocity. The limited resolution of the telescope (HPBW 11") did not allow us to resolve the shell structure. We now report much higher angular resolution observations of CO(2-1), CO(1-0), CN(2-1) and C4H(24-23) made with the SMA, PdB and ALMA interferometers (with synthesized half-power beamwidths of 3", 1" and 0.3", respectively). Although the envelope appears much more intricate at high resolution than with an 11" beam, its prevailing structure remains a pattern of thin, nearly concentric shells. The average separation between the brightest CO shells is 16" in the outer envelope, where it appears remarkably constant. Closer to the star (< 40"), the shell pattern is denser and less regular, showing intermediary arcs. Outside the small (r < 0.3") dust formation zone, the gas appears to expand radially at a constant velocity, 14.5 km s-1, with small turbulent motions. Based on that property, we have reconstructed the 3-D structure of the outer envelope and have derived the gas temperature and density radial profiles in the inner (r < 25") envelope. The shell-intershell density contrast is found to be typically 3. The over-dense shells have spherical or slightly oblate shapes and typically extend over a few steradians, implying isotropic mass loss. The regular spacing of shells in the outer envelope supports the model of a binary star system with a period of 700 years and a near face-on elliptical orbit. The companion fly-by triggers enhanced episodes of mass loss near periastron. The densification of the shell pattern observed in the central part of the envelope suggests a more complex scenario for the last few thousand years. PMID- 29456258 TI - Modifying the Standard Disk Model for the Ultraviolet Spectral Analysis of Disk dominated Cataclysmic Variables. I. The Novalikes MV Lyrae, BZ Camelopardalis, and V592 Cassiopeiae. AB - The standard disk is often inadequate to model disk-dominated cataclysmic variables (CVs) and generates a spectrum that is bluer than the observed UV spectra. X-ray observations of these systems reveal an optically thin boundary layer (BL) expected to appear as an inner hole in the disk. Consequently, we truncate the inner disk. However, instead of removing the inner disk, we impose the no-shear boundary condition at the truncation radius, thereby lowering the disk temperature and generating a spectrum that better fits the UV data. With our modified disk, we analyze the archival UV spectra of three novalikes that cannot be fitted with standard disks. For the VY Scl systems MV Lyr and BZ Cam, we fit a hot inflated white dwarf (WD) with a cold modified disk ( [Formula: see text] ~ a few 10-9M? yr-1). For V592 Cas, the slightly modified disk ( [Formula: see text] ~ 6 * 10-9M? yr-1) completely dominates the UV. These results are consistent with Swift X-ray observations of these systems, revealing BLs merged with ADAF-like flows and/or hot coronae, where the advection of energy is likely launching an outflow and heating the WD, thereby explaining the high WD temperature in VY Scl systems. This is further supported by the fact that the X-ray hardness ratio increases with the shallowness of the UV slope in a small CV sample we examine. Furthermore, for 105 disk-dominated systems, the International Ultraviolet Explorer spectra UV slope decreases in the same order as the ratio of the X-ray flux to optical/UV flux: from SU UMa's, to U Gem's, Z Cam's, UX UMa's, and VY Scl's.

AB - This study investigates the use of pads with high dielectric constant (HDC) materials to alter electromagnetic field distributions in patients during magnetic resonance imaging (MRI). The study was performed with numerical simulations and phantom measurements. An initial proof-of-concept and validation was performed using a phantom at 64 MHz, showing increases of up to 10% in electromagnetic field when using distilled water as the high dielectric material. Additionally, numerical simulations with computational models of human anatomy were performed at 128 MHz. Results of these simulations using barium titanate (BaTiO3) beads showed a 61% increase of [Formula: see text] with a quadrature driven RF coil and a 64% increase with a dual-transmit array. The presence of the HDC material also allowed for a decrease of SAR up to twofold (e.g., peak 10 g averaged SAR from 54 to 22 W/kg with a quadrature driven RF coil and from 27 to 22 W/kg with a dual-transmit array using CaTiO3 powder at 128 MHz). The results of this study show that the use of HDC pads at 128 MHz for MRI spine applications could result in improved magnetic fields within the region of interest, while decreasing SAR outside the region. PMID- 29456260 TI - RF Safety Evaluation of a Breast Tissue Expander Device for MRI: Numerical Simulation and Experiment. AB - This study describes the MRI-related radio frequency (RF) safety evaluation of breast tissue expander devices to establish safety criteria. Numerical simulations and experimental measurements were performed at 64 MHz with a gel phantom containing a breast expander. Additionally, computational modeling was performed (64 and 128 MHz) with an adult female model, containing a virtually implanted breast tissue expander device for four imaging landmark positions. The presence of the breast tissue expander device led to significant alterations in specific absorption rate (SAR) and|B1+|distributions. The main source of SAR alterations with the use of the breast expander device was the saline-filled pouch of the expander. Conversely, the variation of RF magnetic field (B1+) was mainly caused by the metallic port. The measured values of electric field magnitude did not increase significantly due to the introduction of the expander device. The maximum 1g- or 10g-averaged SAR values in tissues near the implant were lower than those expected in other regions of the patient body with normalization of both|B1+|equal to 2 MUT at the coil isocenter and whole body averaged SAR equal to 4W/kg. PMID- 29456261 TI - Insights into Activation of Cobalt Pre-Catalysts for C(sp2)-H Functionalization. AB - The activation of readily prepared, air-stable cobalt (II) bis(carboxylate) pre catalysts for the functionalization of C(sp2)-H bonds has been systematically studied. With the pyridine bis(phosphine) chelate, iPrPNP, treatment of 1 (O2CtBu)2 with either B2Pin2 or HBPin generated cobalt boryl products. With the former, reduction to (iPrPNP)CoIBPin was observed while with the latter, oxidation to the cobalt(III) dihydride boryl, trans-(iPrPNP)Co(H)2BPin occurred. The catalytically inactive cobalt complex, Co[PinB(O2CtBu)2]2, accompanied formation of the cobalt-boryl products in both cases. These results demonstrate that the pre-catalyst activation from cobalt(II) bis(carboxylates), although effective and utilizes an air-stable precursor, is less efficient than activation of cobalt(I) alkyl or cobalt(III) dihydride boryl complexes, which are quantitatively converted to the catalytically relevant cobalt(I) boryl. Related cobalt(III) dihydride silyl and cobalt(I) silyl complexes were also synthesized from treatment of trans-(iPrPNP)Co(H)2BPin and (iPrPNP)CoPh with HSi(OEt)3, respectively. No catalytic silylation of arenes was observed with either complex likely due to the kinetic preference for reversible C-H reductive elimination rather than product- forming C-Si bond formation from cobalt(III). Syntheses of the cobalt(II) bis(carboxylate) and cobalt(I) alkyl of iPrPONOP, a pincer where the methylene spacers have been replaced by oxygen atoms, were unsuccessful due to deleterious P-O bond cleavage of the pincer. Despite their structural similarity, the rich catalytic chemistry of iPrPNP was not translated to iPrPONOP due to the inability to access stable cobalt precursors as a result of ligand decomposition via P-O bond cleavage. PMID- 29456262 TI - Mixed analytical-stochastic simulation method for the recovery of a Brownian gradient source from probability fluxes to small windows. AB - Is it possible to recover the position of a source from the steady-state fluxes of Brownian particles to small absorbing windows located on the boundary of a domain? To address this question, we develop a numerical procedure to avoid tracking Brownian trajectories in the entire infinite space. Instead, we generate particles near the absorbing windows, computed from the analytical expression of the exit probability. When the Brownian particles are generated by a steady-state gradient at a single point, we compute asymptotically the fluxes to small absorbing holes distributed on the boundary of half-space and on a disk in two dimensions, which agree with stochastic simulations. We also derive an expression for the splitting probability between small windows using the matched asymptotic method. Finally, when there are more than two small absorbing windows, we show how to reconstruct the position of the source from the diffusion fluxes. The present approach provides a computational first principle for the mechanism of sensing a gradient of diffusing particles, a ubiquitous problem in cell biology.

AB - Children are considered to be a vulnerabletion when it comes to exposures to hazardous substances. Schools, where children spend about one third of their day, are expected to be a safe environment. Yet, there are many hazardous substances in schools that can be inadvertently or intentionally released and harm the health of students and teachers alike. The purpose of this analysis is to characterize acute chemical release incidents in school settings and identify prevention practices. The acute chemical incident surveillance programs of the Agency for Toxic Substances and Disease Registry (ATSDR) captured 24,748 acute chemical release incidents from 14 states that participated during 2008-2013. We examined 335 of these incidents that occurred at schools. While only 1.3% (n = 335) of all chemical incidents reported to ATSDR occurred in schools, these incidents represented a larger part of the total impacts, including 8.5% of incidents with persons injured, 5.7% of evacuations ordered, and 31.1% of people evacuated. Natural gas (21.8%) and mercury (18.2%) were the chemicals most frequently released. Collecting and analyzing data on acute school chemical releases allows stakeholders to target prevention initiatives and provide a school environment safe from these chemical exposures. PMID- 29456265 TI - Mental Well-Being Differences in Cohabitation and Marriage: The Role of Childhood Selection. AB - Prior studies have found that marriage benefits well-being, but cohabitation may provide similar benefits. An analysis of the British Cohort Study 1970, a prospective survey following respondents to age 42, examines whether partnerships in general, and marriage in particular, influence mental well-being in midlife. Propensity score matching indicates whether childhood characteristics are a sufficient source of selection to eliminate differences in well-being between those living with and without a partner and those cohabitating and married. The results indicate that matching on childhood characteristics does not eliminate advantages to living with a partner; however, matching eliminates differences between marriage and cohabitation for men and women more likely to marry. On the other hand, marriage may provide benefits to women less likely to marry unless they have shared children and are in long-lasting partnerships. Hence, childhood selection attenuates differences between cohabitation and marriage, except for women less likely to marry. PMID- 29456266 TI - Isotonic Regression under Lipschitz Constraint. AB - The pool adjacent violators (PAV) algorithm is an efficient technique for the class of isotonic regression problems with complete ordering. The algorithm yields a stepwise isotonic estimate which approximates the function and assigns maximum likelihood to the data. However, if one has reasons to believe that the data were generated by a continuous function, a smoother estimate may provide a better approximation to that function. In this paper, we consider the formulation which assumes that the data were generated by a continuous monotonic function obeying the Lipschitz condition. We propose a new algorithm, the Lipschitz pool adjacent violators (LPAV) algorithm, which approximates that function; we prove the convergence of the algorithm and examine its complexity. PMID- 29456267 TI - Inorganic carbon and oxygen dynamics in a marsh-dominated estuary. AB - We conducted a free-water mass balance-based study to address the rate of metabolism and net carbon exchange for the tidal wetland and estuarine portion of the coastal ocean and the uncertainties associated with this approach were assessed. We measured open water diurnal O2 and dissolved inorganic carbon (DIC) dynamics seasonally in a salt marsh-estuary in Georgia, U.S.A. with a focus on the marsh-estuary linkage associated with tidal flooding. We observed that the overall estuarine system was a net source of CO2 to the atmosphere and coastal ocean and a net sink for oceanic and atmospheric O2. Rates of metabolism were extremely high, with respiration (43 mol m-2 yr-1) greatly exceeding gross primary production (28 mol m-2 yr-1), such that the overall system was net heterotrophic. Metabolism measured with DIC were higher than with O2, which we attribute to high rates of anaerobic respiration and reduced sulfur storage in salt marsh sediments, and we assume substantial levels of anoxygenic photosynthesis. We found gas exchange from a flooded marsh is substantial, accounting for about 28% of total O2 and CO2 air-water exchange. A significant percentage of the overall estuarine aquatic metabolism is attributable to metabolism of marsh organisms during inundation. Our study suggests not rely on oceanographic stoichiometry to convert from O2 to C based measurements when constructing C balances for the coastal ocean. We also suggest eddy covariance measurements of salt marsh net ecosystem exchange underestimate net ecosystem production as they do not account for lateral DIC exchange associated with marsh tidal inundation. PMID- 29456268 TI - Evidence for ubiquitous preferential particle orientation in representative oceanic shear flows. AB - In situ measurements were undertaken to characterize particle fields in undisturbed oceanic environments. Simultaneous, co-located depth profiles of particle fields and flow characteristics were recorded using a submersible holographic imaging system and an acoustic Doppler velocimeter, under different flow conditions and varying particle concentration loads, typical of those found in coastal oceans and lakes. Nearly one million particles with major axis lengths ranging from ~14 MUm to 11.6 mm, representing diverse shapes, sizes, and aspect ratios were characterized as part of this study. The particle field consisted of marine snow, detrital matter, and phytoplankton, including colonial diatoms, which sometimes formed "thin layers" of high particle abundance. Clear evidence of preferential alignment of particles was seen at all sampling stations, where the orientation probability density function (PDF) peaked at near horizontal angles and coincided with regions of low velocity shear and weak turbulent dissipation rates. Furthermore, PDF values increased with increasing particle aspect ratios, in excellent agreement with models of spheroidal particle motion in simple shear flows. To the best of our knowledge, although preferential particle orientation in the ocean has been reported in two prior cases, our findings represent the first comprehensive field study examining this phenomenon. Evidence of nonrandom particle alignment in aquatic systems has significant consequences to aquatic optics theory and remote sensing, where perfectly random particle orientation and thus isotropic symmetry in optical parameters is assumed. Ecologically, chain-forming phytoplankton may have evolved to form large aspect ratio chains as a strategy to optimize light harvesting.

Recently it has been demonstrated that the settlement of phycodetrital aggregates can induce local changes in the benthic O2 distribution due to confined enrichment of organic material and alteration of the diffusional transport. Here, we show how this microscale O2 shift substantially affects benthic nitrogen cycling. In sediment incubations, the settlement of diatom-aggregates markedly enhanced benthic O2 and NO3- consumption and stimulated NO2- and NH4+ production. Oxygen microprofiles revealed the rapid development of anoxic niches within and underneath the aggregates. During 120 h following the settling of the aggregates, denitrification of NO3- from the overlying water increased from 13.5 MUmol m-2 h 1 to 24.3 MUmol m-2 h-1, as quantified by 15N enrichment experiment. Simultaneously, N2 production from coupled nitrification-denitrification decreased from 33.4 MUmol m-2 h-1 to 25.9 MUmol m-2 h-1, probably due to temporary inhibition of the benthic nitrifying community. The two effects were of similar magnitude and left the total N2 production almost unaltered. At the aggregate surface, nitrification was, conversely, very efficient in oxidizing NH4+ liberated by mineralization of the aggregates. The produced NO3- was preferentially released into the overlying water and only a minor fraction contributed to denitrification activity. Overall, our data indicate that the abrupt change in O2 microdistribution caused by aggregates stimulates denitrification of NO3- from the overlying water, and loosens the coupling between benthic nitrification and denitrification both in time and space. The study contributes to expanding the conceptual and quantitative understanding of how nitrogen cycling is regulated in dynamic benthic environments. PMID- 29456270 TI - Thinking, Fast and Slow? Some Field Experiments to Reduce Crime and Dropout in Chicago. AB - We present the results of three large-scale randomized controlled trials (RCTs) carried out in Chicago, testing interventions to reduce crime and dropout by changing the decision making of economically disadvantaged youth. We study a program called Becoming a Man (BAM), developed by the nonprofit Youth Guidance, in two RCTs implemented in 2009-2010 and 2013-2015. In the two studies participation in the program reduced total arrests during the intervention period by 28-35%, reduced violent-crime arrests by 45-50%, improved school engagement, and in the first study where we have follow-up data, increased graduation rates by 12-19%. The third RCT tested a program with partially overlapping components carried out in the Cook County Juvenile Temporary Detention Center (JTDC), which reduced readmission rates to the facility by 21%. These large behavioral responses combined with modest program costs imply benefit-cost ratios for these interventions from 5-to-1 up to 30-to-1 or more. Our data on mechanisms are not ideal, but we find no positive evidence that these effects are due to changes in emotional intelligence or social skills, self-control or "grit," or a generic mentoring effect. We find suggestive support for the hypothesis that the programs work by helping youth slow down and reflect on whether their automatic thoughts and behaviors are well suited to the situation they are in, or whether the situation could be construed differently.

AB - Neighborhood context can change the effect of a socio-demographic attribute on the risk of suicide. Eight hypotheses about the interactions between neighborhood composition, ethnicity, income, and socially disadvantaged propositions are proposed based on social support, social comparison, and social regulation mechanisms. They are tested with a population-based dataset of all adults (1.4 million) who lived in the greater Stockholm area in the 1990s. On one hand, multilevel analysis shows that suicide risk increases with the level of affluence in one's neighborhood, particularly among individuals with low income. This supports the notion that income comparison can have negative consequences. On the other hand, social welfare recipients are less likely to commit suicide when there are other social welfare recipients in the neighborhood. Suicide risk among immigrants deceases with the proportion of co-ethnics in the neighborhood, confirming previous findings on social support and suicide. However, further analyses show that the protection effect of having co-ethnic neighbors is limited to immigrants from countries with low suicide rates. This study shows that administrative data can be used to examine neighborhood effects on rare outcomes. The findings are relevant to the contemporary trends towards rising income inequality and ethnic diversity.

AB - Pesticide exposure in Ecuador's banana industry reflects political economic and ecological processes that interact across scales to affect human health. We use this case study to illustrate opportunities for applying political ecology of health scholarship in the burgeoning field of global health. Drawing on an historical literature review and ethnographic data collected in Ecuador's El Oro province, we present three main areas where a political ecological approach can enrich global health scholarship: perceptive characterization of multi-scalar and ecologically entangled pathways to health outcomes; critical analysis of discursive dynamics such as competing scalar narratives; and appreciation of the environment-linked subjectivities and emotions of people experiencing globalized health impacts. Rapprochement between these fields may also provide political ecologists with access to valuable empirical data on health outcomes, venues for engaged scholarship, and opportunities to synthesize numerous insightful case studies and discern broader patterns. PMID- 29456273 TI - The Effects of Acute Cannabis Use on Nontraffic Injury Risk: Reviewing the Available Literature and Identifying Ways Forward. AB - Recent evidence has indicated that cannabis use before driving is associated with a modest but increased risk for traffic-related injuries. However, the question of whether recent cannabis use is associated with a greater risk for other types of injuries remains unanswered. Aiming to understand better how acute cannabis use might affect the risk for all causes of injury, we have summarized the limited data available in the literature on the risk of non-traffic injuries associated with recent cannabis use. Very few studies were able to provide estimate risks for all injuries or injuries other than those related to road traffic injuries, with the limited evidence available showing mixed findings. The only significant risk found (in only one study) suggests an inverse association between all injuries and cannabis use. Study designs are limited, and the majority of studies have neither data on acute cannabis use among injured individuals nor a valid control group for estimating injury risk attributable to cannabis. In conclusion, studies of the association between cannabis and non traffic injuries present several limitations, particularly regarding sampling strategies, injury risk assessment for different causes of injury, and a dose response risk relationship with injury. Further studies, incorporating better design for different causes of injury and drug testing, are required to reach firmer conclusions on the association between cannabis use and non-traffic injury risk.

While most Muslim-majority as well as some Western states have been reluctant to adopt harm reduction measures, the Islamic Republic of Iran has done so on a nationwide scale and through a sophisticated system of welfare intervention. Additionally, it has introduced devices of management of 'addiction' (the 'camps') that defy statist modes of punishment and private violence. What legal and ethical framework has this new situation engendered? And what does this new situation tell us about the governmentality of the state? Through a combination of historical analysis and ethnographic fieldwork, the article analyses the paradigm of government of the Iranian state with regard to disorder as embodied by the lives of poor drug (ab)users. PMID- 29456275 TI - Antimicrobial packaging based on E-polylysine bioactive film for the control of mycotoxigenic fungi in vitro and in bread. AB - : E-Poly-l-lysine (E-PL) is a cationic peptide with a broad-spectrum antimicrobial activity. This study investigates the use of E-PL as natural antimicrobial to inhibit fungal growth and to reduce aflatoxins (AFs) production. Antifungal activity of starch biofilms with different concentrations of E-Poly-l lysine (E-PL) was determined in solid medium against Aspergillus parasiticus (AFs producer) and Penicillium expansum. Then, biofilms were tested as antimicrobial devices for the preservation of bread loaf inoculated with A. parasiticus CECT 2681 and P. expansum CECT 2278. Shelf life and AFs content were examined. Biofilms with concentrations of E-PL less than 1.6 mg/cm2 showed no fungal growth inhibition in solid medium, while the antifungal activity of the films with greater than 1.6 mg/cm2 of E-PL was dose dependent. The shelf life of bread inoculated with A. parasiticus was increased by 1 day with the use of films containing 1.6-6.5 mg E-PL/cm2, while shelf life of bread tainted with P. expansum was increased by 3 day with 6.5 mg E-PL/cm2. AFs production was greatly inhibited by E-PL biofilms (93-100%). Thus, E-PL biofilms could be potentially used as antimicrobial device during bread storage as a natural alternative to the synthetic preservatives. Practical applications: E-Polylysin is a natural substance from microbial metabolism. Polylysine has a function to prevent a microbe from proliferating by ionic adsorption in the microbe. E-polylysine has a wide antibacterial spectrum and has an obvious lethal effect on Gram-positive and Gram-negative bacteria, yeast, mold, viruses, etc. It has a good antibacterial effect on the Gram-negative bacteria E. coli and Salmonellae, which are difficult to control with other natural preservatives. E-Polylysine has already been used generally as a food additive in Japan, Korea and other part of world. In the United States, FDA has recognized the polylysine as a GRAS material. Considered the positive results obtained in the study, this compound could be used for the production of antimicrobial biofilms, applied as separator slices in the loaf bread production, to prevent the growth of the mycotoxigenic fungi A. parasiticus and P. expansum, contributing to reduce the use of the synthetically preservatives in bakery industry and also of the negative impact that these compounds could generate on the health of the end users. PMID- 29456276 TI - Effects of natural antimicrobials with modified atmosphere packaging on the growth kinetics of Listeria monocytogenes in ravioli at various temperatures. AB - : The objective of this study was to investigate the antimicrobial effects of cultured sugar/vinegar (CSV) blend and nisin to control the risk of Listeria monocytogenes in ready to cook (RTC) ravioli. Ravioli dough was prepared with 0.1, 0.3, 0.5, 1% CSV blend and 0.1, 0.2, and 0.3% nisin. Inoculated spinach or artichoke raviolis with 2.0 +/- 0.5 log cfu/g of L. monocytogenes were packed aerobically or using modified atmosphere packaging (MAP), and then stored at 4, 10, 17, and 24 degrees C for 60 days. Growth kinetic parameters of the observed data fit well to the Baranyi equation. Ravioli with spinach filling materials yielded a higher risk than that with artichoke. L. monocytogenes was able to survive in ravioli with artichoke, but did not grow. The addition of 1% CSV blend or 0.3% nisin in spinach ravioli with the combination of MAP effectively controlled the growth of L. monocytogenes at the temperature below 10 degrees C. The organoleptic quality of spinach ravioli was not also affected by the application of 1% CSV blend. Therefore, the CSV blend can be recommended to improve the microbial safety and quality of natural RTC ravioli at retail market. Practical applications: The risk of ravioli was affected by the filling materials of ravioli at retail market. Addition of 1% cultured sugar/vinegar blend in dough substantially contributes to the extension of shelf-life of MAP spinach raviolis. classification and regression tree analysis results indicate that refrigeration temperature is the main control factor to affect lag time and growth rate, while packaging method is critical for maximum population density. PMID- 29456277 TI - Differential Attention to Faces in Infant Siblings of Children with Autism Spectrum Disorder and Associations with Later Social and Language Ability. AB - A growing body of literature has begun to explore social attention in infant siblings of children with autism spectrum disorder (ASD) with hopes of identifying early differences that are associated with later ASD or other aspects of development. The present study used eye-tracking to familiar (mother) and unfamiliar (stranger) faces in two groups of 6-month-old infants: infants with no family history of ASD (low-risk controls; LRC), and infants at high risk for ASD (HRA), by virtue of having an older sibling with ASD. HRA infants were further characterized based on autism classification at 24 months or older as HRA- (HRA without an ASD outcome) or HRA+ (HRA with an ASD outcome). For time scanning faces overall, HRA+ and LRC showed similar patterns of attention, and this was significantly greater than in HRA-. When examining duration of time spent on eyes and mouth, all infants spent more time on eyes than mouth, but HRA+ showed the greatest amount of time looking at these regions, followed by LRC, then HRA-. LRC showed a positive association between 6-month attention to eyes and 18-month social-communicative behavior, while HRA- showed a negative association between attention to eyes at 6 months and expressive language at 18 months (all correlations controlled for non-verbal IQ; HRA- correlations held with and without the inclusion of the small sample of HRA+). Differences found in face scanning at 6 months, as well as associations with social communication at 18 months, point to potential variation in the developmental significance of early social attention in children at low and high risk for ASD. PMID- 29456278 TI - Investigation of patterned and non-patterned poly(2,6-dimethyl 1,4-phenylene) oxide based anion exchange membranes for enhanced desalination and power generation in a microbial desalination cell. AB - Quaternary ammonium poly(2,6-dimethyl 1,4-phenylene oxide) (QAPPO) anion exchange membranes (AEMs) with topographically patterned surfaces were assessed in a microbial desalination cell (MDC) system. The MDC results with these QAPPO AEMs were benchmarked against a commercially available AEM. The MDC with the non patterned QAPPO AEM (Q1) displayed the best desalination rate (a reduction of salinity by 53 +/- 2.7%) and power generation (189 +/- 5 mW m- 2) when compared against the commercially available AEM and the patterned AEMs. The enhanced performance with the Q1 AEM was attributed to its higher ionic conductivity and smaller thickness leading to a reduced area specific resistance. It is important to note that Real Pacific Ocean seawater and activated sludge were used into the desalination chamber and anode chamber respectively for the MDC - which mimicked realistic conditions. Although the non-patterned QAPPO AEM displayed better performance over the patterned QAPPO AEMs, it was observed that the anodic overpotential was smaller when the MDCs featured QAPPO AEMs with larger lateral feature sizes. The results from this study have important implications for the continuous improvements necessary for developing cheaper and better performing membranes in order to optimize the MDC. PMID- 29456279 TI - Uncertainty Footprint: Visualization of Nonuniform Behavior of Iterative Algorithms Applied to 4D Cell Tracking. AB - Research on microscopy data from developing biological samples usually requires tracking individual cells over time. When cells are three-dimensionally and densely packed in a time-dependent scan of volumes, tracking results can become unreliable and uncertain. Not only are cell segmentation results often inaccurate to start with, but it also lacks a simple method to evaluate the tracking outcome. Previous cell tracking methods have been validated against benchmark data from real scans or artificial data, whose ground truth results are established by manual work or simulation. However, the wide variety of real-world data makes an exhaustive validation impossible. Established cell tracking tools often fail on new data, whose issues are also difficult to diagnose with only manual examinations. Therefore, data-independent tracking evaluation methods are desired for an explosion of microscopy data with increasing scale and resolution. In this paper, we propose the uncertainty footprint, an uncertainty quantification and visualization technique that examines nonuniformity at local convergence for an iterative evaluation process on a spatial domain supported by partially overlapping bases. We demonstrate that the patterns revealed by the uncertainty footprint indicate data processing quality in two algorithms from a typical cell tracking workflow - cell identification and association. A detailed analysis of the patterns further allows us to diagnose issues and design methods for improvements. A 4D cell tracking workflow equipped with the uncertainty footprint is capable of self diagnosis and correction for a higher accuracy than previous methods whose evaluation is limited by manual examinations. PMID- 29456280 TI - Analyzing survival curves at a fixed point in time for paired and clustered right censored data. AB - In clinical trials, information about certain time points may be of interest in making decisions about treatment effectiveness. Rather than comparing entire survival curves, researchers can focus on the comparison at fixed time points that may have a clinical utility for patients. For two independent samples of right-censored data, Klein et al. (2007) compared survival probabilities at a fixed time point by studying a number of tests based on some transformations of the Kaplan-Meier estimators of the survival function. However, to compare the survival probabilities at a fixed time point for paired right-censored data or clustered right-censored data, their approach would need to be modified. In this paper, we extend the statistics to accommodate the possible within-paired correlation and within-clustered correlation, respectively. We use simulation studies to present comparative results. Finally, we illustrate the implementation of these methods using two real data sets. PMID- 29456281 TI - Foster home integration as a temporal indicator of relational well-being. AB - This study sought to identify factors that contribute to the relational well being of youth in substitute care. Using data from the [BLIND] study, youth responded to a 9-item measure of positive home integration, a scale designed to assess the relational experiences of youth to their caregivers and their integration into the foster home. Data were collected from youth in six month intervals, for an 18-month period of time. Latent growth curve modeling procedures were employed to determine if child, family, and case characteristics influenced youth's home integration trajectories. Results suggest stability in youth reports of home integration over time; however, children who were older at the time of study enrollment and youth who experienced placement changes during the period of observation experienced decreased home integration during the 18 month period. Results suggest youth's perspectives of home integration may in part be a function of the child's developmental stage and their experiences with foster care placement instability. Implications for practice and future research are discussed. PMID- 29456282 TI - Beta approximation of ratio distribution and its application to next generation sequencing read counts. AB - Paired sequencing data are commonly collected in genomic studies to control biological variation. However, existing data processing strategies suffer at low coverage regions, which are unavoidable due to the limitation of current sequencing technology. Furthermore, information contained in the absolute values of the read counts is commonly ignored. We propose a read count ratio processing/modification method, to not only incorporate information contained in the absolute values of paired counts into one variable, but also mitigate the discrete artifact, especially when both counts are small. Simulation shows that the processed variable fits well with a Beta distribution, thus providing an easy tool for down-stream inference analysis. PMID- 29456283 TI - La-Ce isotope measurements by multicollector-ICPMS. AB - The 138La-138Ce decay system (half-life 1.02 * 1011 years) is a potentially highly useful tool to unravel information about the timing of geological processes and about the interaction of geological reservoirs on earth, complementing information from the more popular 147Sm-143Nd and 176Lu-176Hf isotope systems. Previously published analytical protocols were limited to TIMS. Here we present for the first time an analytical protocol that employs MC-ICPMS, with an improved precision and sensitivity. To perform sufficiently accurate La Ce measurements, an efficient ion-chromatographic procedure is required to separate Ce from the other rare earth elements (REE) and Ba quantitatively. This study presents an improved ion-chromatographic procedure that separates La and Ce from rock samples using a three-step column separation. After REE separation by cation exchange, Ce is separated employing an Ln Spec column and selective oxidation. In the last step, a cation clean-up chemistry is performed to remove all remaining interferences. Our MC-ICPMS measurement protocol includes all stable Ce isotopes (136Ce, 138Ce, 140Ce and 142Ce), by employing a 1010 ohm amplifier for the most abundant isotope 140Ce. An external reproducibility of +/ 0.25epsilon-units (2 r.s.d) has been routinely achieved for 138Ce measurements for as little as 150-600 ng Ce, depending on the sample-skimmer cone combinations being used. Because the traditionally used JMC-304 Ce reference material is not commercially available anymore, a new reference material was prepared from AMES laboratory Ce metal (Cologne-AMES). In order to compare the new material with the previously reported isotopic composition of AMES material prepared at Mainz (Mainz-AMES), Cologne-AMES and JMC-304 were measured relative to each other in the same analytical session, demonstrating isotope heterogeneity between the two AMES and different JMC-304 batches used in the literature. To enable sufficiently precise age correction of radiogenic 138Ce and to perform isochron dating, a protocol was developed where La and Ce concentrations are determined by isotope dilution (ID), using an isotope tracer enriched in 138La and 142Ce. The new protocols were applied to determine the variations of Ce isotope compositions and La-Ce concentrations of certified geochemical reference materials (CRMs): BCR-2, BCR-1, BHVO-2, JR-1, JA-2, JB-3, JG-1, JR-1, JB-1b, AGV-1 and one in-house La Palma standard. PMID- 29456284 TI - Spatially-explicit model for assessing wild dog control strategies in Western Australia. AB - Large predators can significantly impact livestock industries. In Australia, wild dogs (Canis lupus familiaris, Canis lupus dingo, and hybrids) cause economic losses of more than AUD$40M annually. Landscape-scale exclusion fencing coupled with lethal techniques is a widely practiced control method. In Western Australia, the State Barrier Fence encompasses approximately 260,000km2 of predominantly agricultural land, but its effectiveness in preventing wild dogs from entering the agricultural region is difficult to evaluate. We conducted a management strategy evaluation (MSE) based on spatially-explicit population models to forecast the effects of upgrades to the Western Australian State Barrier Fence and several control scenarios varying in intensity and spatial extent on wild dog populations in southwest Western Australia. The model results indicate that populations of wild dogs on both sides of the State Barrier Fence are self-sustaining and current control practices are not sufficient to effectively reduce their abundance in the agricultural region. Only when a combination of control techniques is applied on a large scale, intensively and continuously are wild dog numbers effectively controlled. This study identifies the requirement for addressing extant populations of predators within fenced areas to meet the objective of preventing wild dog expansion. This objective is only achieved when control is applied to the whole area where wild dogs are currently present within the fence plus an additional buffer of ~20 km. Our modelling focused on the use of baiting, trapping and shooting; however, we acknowledge that additional tools may also be applied. Finally, we recommend that a cost-benefit analysis be performed to evaluate the economic viability of an integrated control strategy. PMID- 29456285 TI - Improved power and long term performance of microbial fuel cell with Fe-N-C catalyst in air-breathing cathode. AB - Power output limitation is one of the main challenges that needs to be addressed for full-scale applications of the Microbial Fuel Cell (MFC) technology. Previous studies have examined electrochemical performance of different cathode electrodes including the development of novel iron based electrocatalysts, however the long term investigation into continuously operating systems is rare. This work aims to study the application of platinum group metals-free (PGM-free) catalysts integrated into an air-breathing cathode of the microbial fuel cell operating on activated sewage sludge and supplemented with acetate as the carbon energy source. The maximum power density up to 1.3 Wm-2 (54 Wm-3) obtained with iron aminoantipyrine (Fe-AAPyr) catalyst is the highest reported in this type of MFC and shows stability and improvement in long term operation when continuously operated on wastewater. It also investigates the ability of this catalyst to facilitate water extraction from the anode and electroosmotic production of clean catholyte. The electrochemical kinetic extraction of catholyte in the cathode chamber shows correlation with power performance and produces a newly synthesised solution with a high pH > 13, suggesting caustic content. This shows an active electrolytic treatment of wastewater by active ionic and pH splitting in an electricity producing MFC. PMID- 29456286 TI - Examining Thematic Similarity, Difference, and Membership in Three Online Mental Health Communities from Reddit: A Text Mining and Visualization Approach. AB - Objectives: Social media, including online health communities, have become popular platforms for individuals to discuss health challenges and exchange social support with others. These platforms can provide support for individuals who are concerned about social stigma and discrimination associated with their illness. Although mental health conditions can share similar symptoms and even co occur, the extent to which discussion topics in online mental health communities are similar, different, or overlapping is unknown. Discovering the topical similarities and differences could potentially inform the design of related mental health communities and patient education programs. This study employs text mining, qualitative analysis, and visualization techniques to compare discussion topics in publicly accessible online mental health communities for three conditions: Anxiety, Depression and Post-Traumatic Stress Disorder. Methods: First, online discussion content for the three conditions was collected from three Reddit communities (r/Anxiety, r/Depression, and r/PTSD). Second, content was pre-processed, and then clustered using the k-means algorithm to identify themes that were commonly discussed by members. Third, we qualitatively examined the common themes to better understand them, as well as their similarities and differences. Fourth, we employed multiple visualization techniques to form a deeper understanding of the relationships among the identified themes for the three mental health conditions. Results: The three mental health communities shared four themes: sharing of positive emotion, gratitude for receiving emotional support, and sleep- and work-related issues. Depression clusters tended to focus on self-expressed contextual aspects of depression, whereas the Anxiety Disorders and Post-Traumatic Stress Disorder clusters addressed more treatment- and medication-related issues. Visualizations showed that discussion topics from the Anxiety Disorders and Post-Traumatic Stress Disorder subreddits shared more similarities to one another than to the depression subreddit. Conclusions: We observed that the members of the three communities shared several overlapping concerns (i.e., sleep- and work-related problems) and discussion patterns (i.e., sharing of positive emotion and showing gratitude for receiving emotional support). We also highlighted that the discussions from the r/Anxiety and r/PTSD communities were more similar to one another than to discussions from the r/Depression community. The r/Anxiety and r/PTSD subreddit members are more likely to be individuals whose experiences with a condition are long-term, and who are interested in treatments and medications. The r/Depression subreddit members may be a comparatively diffuse group, many of whom are dealing with transient issues that cause depressed mood. The findings from this study could be used to inform the design of online mental health communities and patient education programs for these conditions. Moreover, we suggest that researchers employ multiple methods to fully understand the subtle differences when comparing similar discussions from online health communities. PMID- 29456287 TI - Gamers' insights into the phenomenology of normal gaming and game "addiction": A mixed methods study. AB - In response to calls for further research into the phenomenology of Internet gaming disorder (IGD), we used a community-engaged consensus development approach to evaluate how members of the "gamer culture" describe problematic gaming and the relationship of these descriptions to the proposed IGD criteria. Two focus groups of gamers were recruited at a video game convention. Participants were asked to submit suggestions for signs of game "addiction". Participants discussed and ranked the criteria in order of conceptual importance. The rankings were analyzed quantitatively, and then a multidisciplinary team compared the ranked criteria to the DSM-5 IGD proposed criteria. The strongest agreement between participants' rankings and IGD symptomatology was found for harms/functional impairment due to gaming, continued use despite problems, unsuccessful attempts to control gaming, and loss of interest in previous hobbies and entertainment. There was less support for other IGD criteria. Participants also offered new content domains. These findings suggest that collaborative knowledge-building approaches may help researchers and policymakers understand the characteristics and processes specific to problematic video game play and improve content validity of IGD criteria. Future efforts may benefit from multi-stakeholder approaches to refine IGD criteria and inform theory, measurement and intervention. PMID- 29456288 TI - Distributional learning of subcategories in an artificial grammar: Category generalization and subcategory restrictions. AB - There has been significant recent interest in clarifying how learners use distributional information during language acquisition. Many researchers have suggested that distributional learning mechanisms play a major role during grammatical category acquisition, since linguistic form-classes (like noun and verb) and subclasses (like masculine and feminine grammatical gender) are primarily defined by the ways lexical items are distributed in syntactic contexts. Though recent experimental work has affirmed the importance of distributional information for category acquisition, there has been little evidence that learners can acquire linguistic subclasses based only on distributional cues. Across two artificial grammar-learning experiments, we demonstrate that subclasses can be acquired from distributional cues alone. These results add to a body of work demonstrating rational use of distributional information to acquire complex linguistic structures. PMID- 29456289 TI - The Synergy Between PAV and AdaBoost. AB - Schapire and Singer's improved version of AdaBoost for handling weak hypotheses with confidence rated predictions represents an important advance in the theory and practice of boosting. Its success results from a more efficient use of information in weak hypotheses during updating. Instead of simple binary voting a weak hypothesis is allowed to vote for or against a classification with a variable strength or confidence. The Pool Adjacent Violators (PAV) algorithm is a method for converting a score into a probability. We show how PAV may be applied to a weak hypothesis to yield a new weak hypothesis which is in a sense an ideal confidence rated prediction and that this leads to an optimal updating for AdaBoost. The result is a new algorithm which we term PAV-AdaBoost. We give several examples illustrating problems for which this new algorithm provides advantages in performance. PMID- 29456290 TI - A new precipitation and drought climatology based on weather patterns. AB - Weather-pattern, or weather-type, classifications are a valuable tool in many applications as they characterize the broad-scale atmospheric circulation over a given region. This study analyses the aspects of regional UK precipitation and meteorological drought climatology with respect to a new set of objectively defined weather patterns. These new patterns are currently being used by the Met Office in several probabilistic forecasting applications driven by ensemble forecasting systems. Weather pattern definitions and daily occurrences are mapped to Lamb weather types (LWTs), and parallels between the two classifications are drawn. Daily precipitation distributions are associated with each weather pattern and LWT. Standardized precipitation index (SPI) and drought severity index (DSI) series are calculated for a range of aggregation periods and seasons. Monthly weather-pattern frequency anomalies are calculated for SPI wet and dry periods and for the 5% most intense DSI-based drought months. The new weather-pattern definitions and daily occurrences largely agree with their respective LWTs, allowing comparison between the two classifications. There is also broad agreement between weather pattern and LWT changes in frequencies. The new data set is shown to be adequate for precipitation-based analyses in the UK, although a smaller set of clustered weather patterns is not. Furthermore, intra-pattern precipitation variability is lower in the new classification compared to the LWTs, which is an advantage in this context. Six of the new weather patterns are associated with drought over the entire UK, with several other patterns linked to regional drought. It is demonstrated that the new data set of weather patterns offers a new opportunity for classification-based analyses in the UK. PMID- 29456291 TI - The role of semantic processing in reading Japanese orthographies: an investigation using a script-switch paradigm. AB - Research on Japanese reading has generally indicated that processing of the logographic script Kanji primarily involves whole-word lexical processing and follows a semantics-to-phonology route, while the two phonological scripts Hiragana and Katakana (collectively called Kana) are processed via a sub-lexical route, and more in a phonology-to-semantics manner. Therefore, switching between the two scripts often involves switching between two reading processes, which results in a delayed response for the second script (a script switch cost). In the present study, participants responded to pairs of words that were written either in the same orthography (within-script), or in two different Japanese orthographies (cross-script), switching either between Kanji and Hiragana, or between Katakana and Hiragana. They were asked to read the words aloud (Experiments 1 and 3) and to make a semantic decision about them (Experiments 2 and 4). In contrast to initial predictions, a clear switch cost was observed when participants switched between the two Kana scripts, while script switch costs were less consistent when participants switched between Kanji and Hiragana. This indicates that there are distinct processes involved in reading of the two types of Kana, where Hiragana reading appears to bear some similarities to Kanji processing. This suggests that the role of semantic processing in Hiragana (but not Katakana) reading is more prominent than previously thought and thus, Hiragana is not likely to be processed strictly phonologically. PMID- 29456292 TI - CBM maze-scores as indicators of reading level and growth for seventh-grade students. AB - The technical adequacy of CBM maze-scores as indicators of reading level and growth for seventh-grade secondary-school students was examined. Participants were 452 Dutch students who completed weekly maze measures over a period of 23 weeks. Criterion measures were school level, dyslexia status, scores and growth on a standardized reading test. Results supported the technical adequacy of maze scores as indicators of reading level and growth. Alternate-form reliability coefficients were significant and intermediate to high. Mean maze scores showed significant increase over time, students' growth trajectories differed, and students' initial performance levels (intercepts) and growth rates (slopes) were not correlated. Maze reading level and growth were related to reading level and/or growth on criterion measures. A nonlinear model provided a better fit for the data than a linear model. Implications for use of CBM maze-scores for data based decision-making are discussed. PMID- 29456293 TI - Critical review of elementary flows in LCA data. AB - Purpose: Elementary flows are essential components of data used for life cycle assessment. A standard list is not used across all sources, as data providers now manage these flows independently. Elementary flows must be consistent across a life cycle inventory for accurate inventory analysis and must correspond with impact methods for impact assessment. With the goal of achieving a global network of LCA databases, a critical review of elementary flow usage and management in LCA data sources was performed. Methods: Flows were collected in a standard template from various life cycle inventory, impact method, and software sources. A typology of elementary flows was created to identify flows by types such as chemicals, minerals, land flows, etc. to facilitate differential analysis. Twelve criteria were defined to evaluate flows against principles of clarity, consistency, extensibility, translatability, and uniqueness. Results and discussion: Over 134,000 elementary flows from five LCI databases, three LCIA methods, and four LCA software tools were collected and evaluated from European, North American, and Asian Pacific LCA sources. The vast majority were typed as "Element or Compound" or "Group of Chemicals" with less than 10% coming from the other seven types Many lack important identifying information including context information (environmental compartments), directionality (LCIA methods generally do not provide this information), additional clarifiers such as CAS numbers and synonyms, unique identifiers (like UUIDs), and supporting metadata. Extensibility of flows is poor because patterns in flow naming are generally complex and inconsistent because user defined nomenclature is used. Conclusions: The current shortcomings in flow clarity, consistency, and extensibility are likely to make it more challenging for users to properly select and use elementary flows when creating LCA data and make translation/conversion between different reference lists challenging and loss of information will likely occur. Recommendations: We recommend the application of a typology to flow lists, use of unique identifiers and inclusion of clarifiers based on external references, setting an exclusive or inclusive nomenclature for flow context information that includes directionality and environmental compartment information, separating flowable names from context and unit information, linking inclusive taxonomies to create limited patterns for flowable names, and using an encoding schema that will prevent technical translation errors.

AB - Bioactive glasses (BGs) are excellent delivery systems for the sustained release of therapeutic ions and have been extensively studied in the context of bone tissue engineering. More recently, due to their osteogenic properties and expanding application to soft tissue repair, BGs have been proposed as promising materials for use at the osteochondral interface. Since hypoxia plays a critical role during cartilage formation, we sought to investigate the influence of BGs releasing the hypoxia-mimicking agent cobalt (CoBGs) on human mesenchymal stem cell (hMSC) chondrogenesis, as a novel approach that may guide future osteochondral scaffold design. The CoBG dissolution products significantly increased the level of hypoxia-inducible factor-1 alpha in hMSCs in a cobalt dose dependent manner. Continued exposure to the cobalt-containing BG extracts significantly reduced hMSC proliferation and metabolic activity, as well as chondrogenic differentiation. Overall, this study demonstrates that prolonged exposure to cobalt warrants careful consideration for cartilage repair applications. PMID- 29456296 TI - Back to basics.... PMID- 29456297 TI - Double pronged strategy with incremental efforts in generating awareness on oral hygiene day. PMID- 29456295 TI - User-Centered Design for Psychosocial Intervention Development and Implementation. AB - The current paper articulates how common difficulties encountered when attempting to implement or scale-up evidence-based treatments are exacerbated by fundamental design problems, which may be addressed by a set of principles and methods drawn from the contemporary field of user-centered design. User-centered design is an approach to product development that grounds the process in information collected about the individuals and settings where products will ultimately be used. To demonstrate the utility of this perspective, we present four design concepts and methods: (a) clear identification of end users and their needs, (b) prototyping/rapid iteration, (c) simplifying existing intervention parameters/procedures, and (d) exploiting natural constraints. We conclude with a brief design-focused research agenda for the developers and implementers of evidence-based treatments. PMID- 29456298 TI - Reactive lesions of oral cavity: A retrospective study of 659 cases. AB - Objective: This study reviews, analyzes, and compares the demographic data, histopathological features and discusses the treatment and prognosis of reactive lesions (RLs). Materials and Methods: Retrospective study was performed on the departmental archives from July 2006 to July 2016 (total 5000 cases) comprising of 659 cases of RLs of the oral cavity. The recorded data included age, gender, size, site, duration, habits, etiology, histopathological diagnosis, treatment, and prognosis. Results: The most common lesion was found to be inflammatory fibrous hyperplasia (47%) followed by pyogenic granuloma (PG) (27.16%) and the least cases were of peripheral giant cell granuloma (1.6%). The mean age for the occurrence was 4th-5th decade in all the RL's exceptperipheral ossifying fibroma (POF) which presented in the third decade. Female predominance was noted in all lesions except irritational FIB. The sizes of majority of the lesions were approximately 0.5-1 cm. The common sites were anterior maxilla followed by posterior mandible and least in tongue with no associated habits (82.2%). The duration of all the lesions was seen to be <1 year. Majority of them presented with poor oral hygiene status (87.2%). Recurrences were present in 13.5% of surgically excised lesions. Conclusion: The RLs present commonly in oral cavity secondary to injury and local factors which can mimic benign to rarely malignant lesions. The clinical and histopathological examination helps to categorize the type of lesions. The complete removal of local irritants with follow-up and maintenance of oral hygiene helps to prevent the recurrences of such lesions. PMID- 29456299 TI - Atomic Force Microscopy: A three-dimensional reconstructive tool of oral microbiota in gingivitis and periodontitis. AB - Aim: This study aims to ascertain the advantages of Atomic Force Microscopy (AFM) in the morphologic study of microorganisms and their interactions within the subgingival biofilm in patients with gingivitis and periodontitis. Settings and Design: Conducted a study on twenty patients, ten patients with severe periodontitis with probing the pocket depth of >=8 mm, with a clinical attachment loss (CAL) of >=6 mm CAL and ten patients with gingivitis: >=5 mm pocket depth, and no attachment loss, was selected for the study. Materials and Methods: Bacterial biofilms were collected and slide preparation done. Morphological study was done using AFM. AFM consists of a cantilever-mounted tip, a piezoelectric scanner, a photodetector diode, a laser diode, and a feedback control. The laser beam is reflected from back of the cantilever into the quadrant of the photodetector. AFM works on the principle of interaction between the tip and the sample which causes the cantilever to deflect, thereby changing the position of laser onto the photodetector. Methodology used for studying the bacteria through AFM includes the following: (1) Probe type: Platinum coated silicon nitrate tip. (2) Probe force: 0.11 N/m. (3) Probe geometry: Triangular shaped tip. (4) Probe frequency: 22 KHz. (5) Probe immobilization: Used in Contact mode. AFM Solver Pro M (NT-MDT) equipped with ETALON probe was used to take images in Nova software. Results: The investigation showed various morphological features, such as shape, size, and secretory product-like vesicles of the bacterial species involved in gingivitis and periodontitis. More bacterial surface details were studied by reproducing a three-dimensional reconstruction using AFM. Conclusions: The morphological variations of bacteria of different sizes, and shapes, cell wall structures, secretory product-like vesicles flagellated and filamentous microorganisms, polymorphonuclear leukocytes, and bacterial coaggregation analysis were done by AFM. Results of the present study conclude that AFM is a quite a reliable method for studying morphology of bacterial species involving periodontal diseases and is also used to study microbial interactions in biofilm. PMID- 29456300 TI - Comparative evaluation of the efficacy of a herbal mouthwash and chlorhexidine mouthwash on select periodontal pathogens: An in vitro and ex vivo study. AB - Background: Several herbal mouthwash and herbal extracts have been tested in vitro and in vivo in search of a suitable adjunct to mechanical therapy for long term use. In this study, we aimed to look at the antimicrobial effect of the herbal mouthwash and chlorhexidine (CHX) mouthwash on select organisms in in vitro test and an ex vivo model. Materials and Methods: The antimicrobial effects were determined against standard strains of bacteria that are involved in different stages of periodontal diseases. The in vitro tests included determination of minimum inhibitory concentration (MIC) using broth dilution and agar diffusion. In the ex vivo part of the study supragingival dental plaque were obtained from 20 periodontally healthy adult volunteers. Descriptive analysis was done for the entire quantitative and qualitative variable recorded. Results: The MIC by broth dilution method found no statistically significant difference between the mouthwashes. The agar dilution method showed CHX was more effective as compared to the herbal mouthwash against standard strains of Streptococcus mutans, Streptococcus sanguinis, and Aggregatibacter actinomycetemcomitans. However, no difference was observed between the mouthwashes for Porphyromonas, Pseudomonas aeruginosa, and Fusobacterium nucleatum. The ex vivo results conclude that none of the selected mouthwashes were statistically significantly different from each other. Conclusion: In the present study, CHX showed higher levels of antimicrobial action than the herbal mouthwash against bacterial species. The results reinforce the earlier findings that the in vitro testing is sensitive to methods and due diligence is needed when extrapolating the data for further use. However, long-term use and in vivo effectiveness against the periopathogens need to be tested in well-planned clinical trials. PMID- 29456301 TI - Correlative analysis of plasma and urine neopterin levels in the pre- and post menopausal women with periodontitis, following nonsurgical periodontal therapy. AB - Context: Periodontitis is an inflammatory condition which is distinguished by the devastation of the supported tooth structures. In such inflammatory conditions, some biomarkers such as neopterin will be secreted and elevated in the body fluids, which can be used as a diagnostic marker for the present and future disease activity. Aims: Assessment of the neopterin as a biomarker in inflammatory conditions such as menopause and periodontitis. Settings and Design: A cross-sectional interventional study. Materials and Methods: Sixty female individuals with a mean age of 40-60 years with chronic periodontitis were included in this study. All were categorized into two groups of thirty each, depending on their menstrual history: Group I - thirty premenopausal women and Group II - thirty postmenopausal women. Urine and plasma were collected from both groups to estimate neopterin levels. ELISA kit was used to assess the neopterin levels at baseline and after 3 months of nonsurgical periodontal therapy (NSPT). Statistical Analysis Used: IBM SPSS version 21 software. Results: A significant depreciation in the mean values of all the parameters from baseline to 3 months (P < 0.001), in the intragroup analysis, was observed. Plasma (0.006) and urine (0.004) reduction was seen. Conclusions: In both the groups, in 3 months after NSPT, decreased neopterin levels were found, suggesting that the NSPT is the definitive therapy. Further, suggesting that, neopterin levels in the plasma and urine can be used as an index to identify the periodontal inflammation and destruction. PMID- 29456302 TI - Impact of mandibular third molar extraction in the second molar periodontal status: A prospective study. AB - Aim: The aim of the present study was to assess the periodontal condition and sensitivity of second mandibular molars after the extraction of the adjacent third molar, while also assessing the quality of life of the patients. Materials and Methods: Twenty-three healthy patients were assessed in terms of probing depth, gingival height, gingival thickness, dental sensitivity, plaque index and bleeding on probing (adjacent second mandibular molar), before the surgical procedure, as well as 60 and 180 days after the surgery. The following data were also recorded and measured: the position and size of the impacted teeth; the size of the alveoli after surgery and the quality of life of the patient. Results: Significant differences were found for probing depth and gingival height before and after 180 days. The plaque index increased significantly after surgery (P = 0.004), as did bleeding on probing. No significant difference was found for the quality of life. The size of the third molar extracted was correlated with bleeding on probing 180 days after the surgery. Conclusion: An improvement was noted in the periodontal condition of the second mandibular molars after the extraction, based on the assessments of probing depth and gingival height. The position of the third molar affected the periodontal condition of the second mandibular molar. No alterations were recorded for dental sensitivity or the quality of life after the extraction. PMID- 29456303 TI - Impact of nonsurgical periodontal therapy on total antioxidant capacity in chronic periodontitis patients. AB - Aim: The aim of this study was to determine the utility of plasma total antioxidant capacity (TAC) as marker of periodontal disease by estimating TAC of periodontally healthy and chronic periodontitis patients and the impact of scaling and root planning on total antioxidant status of periodontitis patients. Materials and Methods: Blood plasma samples were collected from randomly selected eighty individuals (40 periodontally healthy controls and 40 chronic periodontitis patients), with an age range of 20-45 years and were analyzed for TAC by ferric reducing antioxidant power assay. Scaling and root planing was performed in periodontitis patients, and TAC level was measured again after 3 weeks. Data were analyzed with t-test, using SPSS software (PSAW, Windows version 18.0). Results: The mean plasma TAC was significantly lower (792.33 +/- 124.33 MUmol/L, P < 0.001) in chronic periodontitis patients compared to healthy control (1076.08 +/- 193.82 MUmol/L). Plasma TAC level increased significantly (989.75 +/ 96.80, P < 0.001) after scaling and root planing. Conclusions: An inverse relationship exists between plasma TAC and severity of chronic periodontitis suggesting disturbed oxidant-antioxidant balance in chronic periodontitis. Scaling and root planing resulted in the restoration of TAC to normal levels. These results are important from the perspective of including antioxidants in periodontal therapy regime to boost up body's antioxidant defense system and to reduce oxidative stress-mediated periodontal tissue damage. We concluded that TAC can be used as a biomarker to evaluate the health of periodontium. PMID- 29456304 TI - Effect of supragingival oral irrigation as an adjunct to toothbrushing on plaque accumulation in chronic generalized gingivitis patients. AB - Aim: The aim of this study was to evaluate the efficacy of supragingival oral irrigation either with water or different concentrations of chlorhexidine (CHX) digluconate as an adjunct to toothbrushing on plaque accumulation in chronic generalized gingivitis patients. Materials and Methods: Fifty patients were randomly allocated into five groups. Group 1: toothbrushing alone, Group 2: toothbrushing with mouthwash, Group 3: toothbrushing with water irrigation, Group 4: toothbrushing with 0.0075% CHX digluconate (36 mg) supragingival irrigation, and Group 5: toothbrushing with 0.02% CHX digluconate (96 mg) supragingival irrigation. The collected data were subjected to statistical analysis. Statistical Analysis: Descriptive data were obtained for all outcome variables and reported as mean +/- standard deviation. The Student's t-test, Chi-square test, and one-way analysis of variance (ANOVA) were applied for the statistical evaluation of means and comparisons of proportions, and post hoc Bonferroni test was used for multiple comparisons after the application of the ANOVA test for comparison within the groups. Results: When intergroup difference of the mean differences was compared for individuals using toothbrushing along with 0.0075% CHX digluconate irrigation and those using toothbrushing along with 0.02% CHX digluconate irrigation from BL-14, BL-28, and between 14 and 28 days, it was found to be statistically nonsignificant. Conclusions: In our study, the CHX digluconate concentration for mouthwash and oral irrigation in addition with toothbrushing was found to be same, i.e., <50 mg for improving the gingival health by reducing gingival inflammation. PMID- 29456305 TI - A clinicoradiographic assessment of 1% metformin gel with platelet-rich fibrin in the treatment of mandibular grade II furcation defects. AB - Background: Management of furcation defects is challenging, and constantly newer therapeutic strategies are evolving. Platelet-rich fibrin (PRF) is successfully used alone and in combination with various agents in the furcation defects. Lately, metformin (MF), a second generation biguanide has gained popularity owing to its osteogenic potential. Aims and Objectives: The aim of the present study was to evaluate the clinical and radiographic effectiveness of open flap debridement (OFD) and PRF when compared to OFD + PRF + 1% MF gel in the management of mandibular Grade II furcation defects. Materials and Methods: Thirty mandibular grade II furcation defects were stratified into two groups; in one group OFD and PRF is used, and the other group had an additional MF gel with PRF in OFD. Clinical parameters such as plaque index, modified sulcus bleeding index, probing pocket depth (PD), relative vertical attachment level (RVAL), and relative horizontal attachment level (RHAL) were recorded at baseline and at 6 months. Radiovisiography and ImageJ software were used to evaluate the intrabony defect depth. Results: The OFD + PRF + MF group showed significantly higher probing PD reduction, RVAL and RHAL gain than the OFD + PRF group. Conclusions: PRF when combined with a potential osteogenic agent like MF can provide a better therapeutic benefit to a furcation involved tooth. PMID- 29456306 TI - Chronic periodontitis among diabetics and nondiabetics aged 35-65 years, in a rural block in Vellore, Tamil Nadu: A cross-sectional study. AB - Background: Chronic periodontitis is a common cause of poor oral health globally. Those at higher risk of this preventable and easily treatable condition need to be identified so that efforts can be taken to decrease disease burden and subsequent consequences. Aims: The aims of the study were (1) To compare the prevalence of chronic periodontitis among individuals with and without type 2 diabetes, aged 35-65 years from a rural block in Vellore, Tamil Nadu and (2) to assess risk factors for chronic periodontitis among individuals with diabetes. Settings and Design: A cross-sectional study was done in nine villages of Kaniyambadi block, Vellore, between October 2015 and July 2016 among participants aged 35-65 years of a previous cross-sectional survey which had identified individuals with and without type 2 diabetes. Materials and Methods: Chronic periodontitis was assessed using the Community Periodontal Index and Treatment Needs index. Oral hygiene was assessed clinically using the Simplified Oral Hygiene Index. Diabetes was defined as on medication for type 2 diabetes or detected to have fasting blood glucose >=126 mg/dl (in a previous survey). Statistical Analysis: Chi-square test and odds ratios (adjusted using logistic regression) were used to study risk factors for periodontitis among those with diabetes. Results: Prevalence of chronic periodontitis was 45.9% (95% confidence interval [CI]: 40.88%-50.9%) among 98 individuals with diabetes and 35.6% (95% CI: 30.91-40.29%) among 104 individuals without diabetes. Poor oral hygiene (odds ratio: 8.33, 95% CI: 3.33-25.00), low socioeconomic status (odds ratio: 3.19, 95% CI: 1.00-10.12), and smoking (odds ratio: 3.51, 95% CI: 1.17-10.51) were associated with periodontitis among diabetics. Conclusions: Individuals with type 2 diabetes have a higher prevalence of periodontitis. As poor oral hygiene is a strong risk factor for periodontitis, there is a need for targeted education regarding dental hygiene to reduce this preventable condition. PMID- 29456307 TI - Awareness, knowledge, and attitude of patients toward dental implants - A questionnaire-based prospective study. AB - Background: In developing nations like India awareness and education about dental implants as a treatment modality is still scanty. Aim: The study was conducted to determine the awareness, knowledge, and attitude of patients toward dental implants as a treatment modality among the general population and to assess the influence of personality characteristics on accepting dental implants as a treatment modality in general and as well as treatment group. Materials and Methods: A structured questionnaire-based survey was conducted on 500 randomly selected participants attending the outpatient department. The study was conducted in 2 parts. In the first part of the study, level of awareness, knowledge, and attitude was assessed. In the second part of the study, interactive educational sessions using audiovisual aids were conducted following which a retest was conducted. The participants who agreed to undergo implant treatment were followed up to assess their change in attitude towards dental implants posttreatment. Thus pain, anxiety, functional, and esthetic benefits were measured using visual analog scale. They were further followed up for 1 year to reassess awareness, knowledge, and attitude towards dental implants. Results: A total of 450 individuals completed the questionnaires. Only 106 individuals agreed to participate in the educational sessions and 83 individuals took the retest. Out of these, only 39 individuals chose implants as a treatment option. A significant improvement in the level of information, subjective and objective need for information, was noted after 1 year. Conclusion: In this study, a severe deficit in level of information, subjective and objective need for information towards, dental implants as a treatment modality was noted. In the treatment group, a significant improvement in perception of dental implant as a treatment modality suggests that professionally imparted knowledge can bring about a change in the attitude. PMID- 29456308 TI - Gingival enlargement unveiling Crohn's disease - A report of a rarefied case. AB - This article highlights a peculiar case of Crohn's disease (CD) with the primary presenting symptom as localized gingival overgrowth in the anterior region of maxilla. The patient underwent surgical treatment with external bevel gingivectomy procedure. Follow-up after 6 months revealed no recurrence. A final diagnosis of CD was made, after following histopathological evaluation of the gingival biopsy and other special investigations. It is thus crucial to associate the localized granulomatous gingival overgrowth to systemic signs of CD. Intraoral occurrence preceding intestinal involvement is very rare in CD with an incidence of about 8%-9% of patients. Therefore, precise diagnosis, treatment planning, and timely management are vital to the overall health and welfare of patients. PMID- 29456309 TI - Idiopathic peripheral ossifying fibroma in a young adolescent girl: A very rare clinical presentation. AB - The use of the term "fibroma" for any soft-tissue lesion or gingival lesion by general practitioners has led to inadequate diagnosis of quite a few rare entities. The occurrence of gingival lesions in adolescent female patients is a routine clinical finding. The site of occurrence of such a lesion is of prime significance, as the rarity of these lesions is determined by the site and size of the lesion. On the other hand, the dilemma over the diagnosis of peripheral ossifying fibroma (POF) versus peripheral odontogenic fibroma still continues. Commonly used synonyms for POF include calcifying fibroblastic granuloma, peripheral fibroma with calcification, peripheral cementifying fibroma, and calcifying or ossifying fibrous epulis. The present case report deals with the management of a unique case of POF between two maxillary central incisors in an adolescent female child patient, followed up to 2-year postsurgical excision. PMID- 29456310 TI - Applications of a modified palatal roll flap in peri-implant soft-tissue augmentation - A case series. AB - Abrams's palatal roll technique has been used extensively to augment peri-implant soft tissues in the maxillary esthetic zone and has seen numerous modifications. An adaptation of the palatal roll technique is described here and its simplicity of application in three different scenarios is demonstrated. At second-stage implant surgery, a partial thickness initial incision followed by a palatal subepithelial dissection at the site of implant was done and a connective tissue graft with a buccal pedicle was obtained. The graft was rolled under the buccal flap and allowed to heal with the support of a healing abutment. The graft healed uneventfully and provided excellent contours of tissues around the implant. The procedure demonstrated good results for augmentation of a buccal ridge deficiency, for covering exposed and unsightly implant fixtures and was also done with a papilla preservation incision. In addition, a second surgical site to obtain the connective tissue graft was avoided. PMID- 29456311 TI - Management of fenestration using bone allograft in conjunction with platelet-rich fibrin. AB - Fenestration and dehiscence are said to be anatomical variations of cortical bone and not true pathological entities. They represent window-like defects covered by periosteum and overlying gingiva with or without the intact marginal bone. The etiology of such defects is still unclear, though many hypotheses such as occlusal traumatism, trauma, and variation in root bone angulation have been put forward. Diagnosis of such defects is challenging clinically, and they cannot be appreciated in conventional radiographs. In many instances, they are accidentally discovered during periodontal and oral surgical procedures. These defects, if not treated, can affect prognosis and complicate healing of the affected teeth. Treatment of such cortical bony defects is challenging and involves the use of potential regenerative materials to aid in regeneration. This case report describes the successful management of such a defect, discovered through exploratory flap approach, using PRF in conjunction with bone allograft. PMID- 29456312 TI - Long-term effect of Lactobacillus brevis CD2 (Inersan(r)) and/or doxycycline in aggressive periodontitis. AB - Context: The over usage and broad use of antibiotics resulted in the emergence of resistant microorganisms to the drugs which also disturb the indigenous microflora, which include the Lactobacillus in the oral cavity. Hence, it is preferred to avoid the use of antibiotics. Aims: The hypothesis tested in this study was that 14 days of treatment with Lactobacillus brevis CD2 lozenges, L. brevis CD2 with oral doxycycline, or doxycycline alone would have a beneficial effect on periodontal health after 5 months. Settings and Design: It was a randomized clinical trial. Materials and Methods: Eighteen nonsmoking patients aged 14-35 years, with aggressive periodontitis, were randomized to receive 14 days of treatment with L. brevis CD2 lozenges (two lozenges daily), L. brevis CD2 lozenges with oral doxycycline (100 mg tablet once daily), or doxycycline alone. Saliva samples were taken on day 0, 2 weeks, 2 months, and 5 months. Clinical parameters (plaque index, gingival index, probing pocket depth, and clinical attachment level) and microbiological parameters (lactobacilli and Aggregatibacter actinomycetemcomitans) were evaluated. Statistical Analysis Used: Changes between groups were evaluated using repeated measure analysis of variance. Results: All clinical parameters shown to be numerically improved at 5 months when compared with baseline in all the three groups. The improvement (P < 0.01) in gingival index was statistically significant, and the intergroup results were also statistically significant (P < 0.01). Conclusions: Fourteen days of treatment with lozenges having L. brevis CD2 have a lasting effect on clinical measures of aggressive periodontitis, particularly gingival index. This effect appears to be equivalent to that produced by doxycycline. PMID- 29456313 TI - Child sexual abuse: the suffering untold. PMID- 29456315 TI - Stressful life events and severity of alcohol consumption in male psychiatric inpatients. AB - Aim: To assess the levels of alcohol consumption and the level of stress faced by male patients hospitalized with psychiatric disorders in a military hospital. Materials and Methods: This cross-sectional study was conducted on 100 consecutive patients admitted to a tertiary care psychiatric center and 100 controls. The patients with psychiatric ailments were first stabilized mentally and physically and then assessed. For the collection of demographic data, a questionnaire was prepared which was administered to all patients. The Armed Forces Medical College Life Events scale was used for the assessment of stressful life events. The Michigan Alcohol Screening Test (MAST) was applied as a screening procedure for alcohol use disorder. For assessing the severity of alcohol consumption, the Hilton Drinking Behavior Questionnaire (HDBQ) was utilized. Results: Analysis revealed that 16% of the psychiatric patients scored above the cutoff score on the MAST compared to 2% of controls. On the HDBQ, 22% of the psychiatric patients had a significant score compared to 4% of controls. Patients with psychiatric disorders experienced significantly more number of life events compared to the controls irrespective of the length of service. The Psychiatric group experienced significantly more life change units both in 1-year prior and in lifetime period. Conclusion: Psychiatric patients face significantly higher stressful life events, experience significantly more life changes, and consume significantly more alcohol as compared to healthy participants. PMID- 29456314 TI - Child sexual abuse and the development of psychiatric disorders: a neurobiological trajectory of pathogenesis. AB - Child sexual abuse (CSA) is an important public health problem with long-standing neurobiological, developmental, and psychiatric abnormalities. The present review analyzes the long-term effects of CSA from a developmental, psychiatric morbidity, neurochemical and neurobiological perspective and then tries to posit a developmental neurobiological trajectory from CSA to the genesis of psychopathology in later life. The role of various neurotransmitters such as serotonin and dopamine affected by CSA are discussed. Serotonin abnormalities have been reported in various studies among participants exposed to CSA. Structures such as the prefrontal cortex, superior temporal gyrus, corpus callosum, parietal lobes, hippocampus, and cerebellum all demonstrate volumetric and structural changes in response to the trauma of CSA. Neurocognitive studies demonstrate memory and spatial awareness as well as decrements in general cognitive performance and memory when compared to normal individuals. The hypothalamic-pituitary-adrenal axis has also been implicated in CSA, and there is an alteration in corticotropin-releasing hormone response due to the continuous cumulative trauma of CSA. This paper also reviews a section on the role of genetic and epigenetic factors in the development of psychiatric disorders as a result of exposure to episodes of CSA where studies have demonstrated changes in DNA methylation in response to CSA. This review tries to hypothesize a developmental trajectory framework which is individual for every case where exposure to CSA may lead to psychopathology and psychiatric morbidity later in life. Rapid and emerging fields such as developmental traumatology in relation to CSA are also discussed. PMID- 29456316 TI - Prevalence and patterns of tobacco use and nicotine dependence among males industrial workers. AB - Background: Tobacco use is an important preventable health risk factor in India. Aim: This study was carried out to estimate the prevalence of current tobacco use, factors and extent of dependence associated with its use among male workers of an industrial organization. Materials and Methods: A total of 759 participants randomly selected from the population of employees were administered questionnaire in Hindi containing demographic profile, patterns of smoking, and use of smokeless tobacco and alcohol. Results: Forty-one percent of the surveyed males (n = 750) used tobacco either by smoking or smokeless method or both (9.7% used both, 23.4% smoked, and 27.3% used smokeless tobacco). The maximum percentage was among the 26-30 years' age group, and the married persons (45.4%, OR = 2.17, P < 0.05). Tobacco use was associated with lower educational qualifications, history of tobacco use in family members, and drinking alcohol. Seventy-two percent of the nicotine users reported being influenced by their peers in initiating the habit, 59.4% of the users reported being advised to stop tobacco use by a health professional, and 52.9% had attempted quitting the habit more than once. Twenty percent of our sample were dependent on nicotine and the highest prevalence was seen in those using both smoking and the smokeless tobacco. Conclusions: The Prevalence of Tobacco Use and Nicotine Dependence among male industrial employees is significant and necessitates Tobacco awareness and cessation programs regarding Tobacco use. PMID- 29456317 TI - Clinico-psycho-social profile of patients brought under consultation-liaison psychiatry care in a large tertiary care referral hospital. AB - Objective: The aim of this study was to access the clinico-psycho-social profile of patients brought under consultation-liaison (CL) psychiatry care in a large tertiary care referral hospital. Materials and Methods: This study included all patients who were referred for CL psychiatry from among the inpatients in the hospital and the emergency department (during off working hours of the hospital) over a period of 1 year. Data were obtained and analyzed in terms of where was the referral placed, by whom, the reason for placing the referral, the primary medical/surgical diagnosis of the patient, the presenting complaints, any past psychiatric history, the psychiatric diagnosis (as per the International Classification of Diseases, Tenth Edition), the investigations advised and their reports, the treatment advised (psychotherapeutic and psychopharmacological), the sociodemographic profile of the patients, and the follow-up details. Results: A total of 157 patients were referred to the CL unit over the study period. Out of these, 125 patients were referred among the inpatients and 32 from the emergency department of the hospital. Majority of the patients were in the age group of 25 50 years and were male. The majority of the referrals were made by general physician; most of the referrals were placed from emergency department. The most common reason for referral was for altered sensorium and behavioral abnormalities. The most common diagnosis was delirium followed by depressive episode and alcohol dependence syndrome. Conclusion: There was higher representation of delirium and alcohol-related cases in our study compared to older studies. PMID- 29456318 TI - Characteristics of suicidal attempts among farmers in rural South India. AB - Background: Globally, farming as an industry is considered a high-risk occupation for suicides. Certain states in India like Karnataka have a suicide rate higher than the national average, and this is generally attributed to the farmers' suicide. Aims: The aim is to study the characteristics of suicidal attempts among the farmer community in South India, with special emphasis on gender differences, modes used, and the immediate precipitant causes. Materials and Methods: Retrospective, case register-based, explorative-descriptive study of 426 consecutive medicolegal case files of patients whose stated occupation was farming and who were admitted as cases of deliberate self-harm or suicide attempt to a rural tertiary care hospital in rural South India. Results: Out of the 426 farmers who attempted suicide, majority were male (355, 83.3%), in the age group of 21-40 years (318, 75%), married (358, 84%), and belonging to lower socioeconomic status (268, 62.9%). About 54% of them had attempted suicide by consuming pesticides (230). Surprisingly, 183 (43%) and 86 (20.2%) reported the immediate precipitant as being relationship issues and marital conflict, respectively, and only 100 (23.5%) attributed it to financial reasons. Females were significantly associated with a past history of suicidal attempt while males tended to abuse alcohol before an attempt more frequently. Conclusions: Pesticide poisoning was the most common mode for attempting suicide among the farmers. Contrary to public perception and other studies, relationship, and marital issues, not financial reasons were found to be the most common immediate precipitant for the attempters in our study. PMID- 29456319 TI - Lifetime alcohol consumption and severity in alcohol dependence syndrome. AB - Introduction: Alcohol dependence syndrome is a major public health issue globally and is responsible for significant morbidity and mortality. The total dose of alcohol consumed has been linked to liver diseases, pancreatitis, and other alcohol-related medical consequences. However, this has not been studied in relation to severity of dependence; although it is well known that alcohol causes neuronal damage, which in turn potentiates dependence. Thus, there is a need to study the relationship between the amount of alcohol consumed and severity of dependence. Materials and Methods: A total of 165 consecutive cases of alcohol dependence syndrome were studied in a General Hospital Psychiatry Unit at a tertiary care hospital. Addiction Severity Index (ASI) was used to evaluate the severity of alcohol dependence, and Life Time Alcohol Consumption (LTAC) was evaluated by taking careful history. Correlation coefficients were calculated between ASI and LTAC. Group differences were analyzed using t-test. Results: There was a significant correlation between ASI and LTAC (r = 0.162, P = 0.032), which was highly significant in the subgroup without medical complications (r = 0.250, P = 0.003). A similar correlation in the medical complications subgroup was not significant. Conclusions: Lifetime alcohol consumption co-related with the severity of alcohol dependence, particularly in those presenting without medical complications (i.e., those with behavioral and social consequences, and injuries). PMID- 29456320 TI - Failure to utilize feedback during explicit decision-making task in alcohol dependent patients. AB - Background: Patients who are diagnosed with alcohol-dependent syndrome (ADS) are shown to have neuropsychological deficits, especially executive function (EF) deficits. Among the EFs, decision-making is one such function which has consistently been shown to be impaired in people who are dependent on alcohol, compared to controls. Decision-making in this population is usually assessed with gambling-type tasks. However, some of these tasks are ambiguous, work on chance factors, rarely match with real-life gambling situations, and/or involve nonconscious mechanisms. Materials and Methods: The current study compared 26 male patients with ADS (P-ADS) with equal number of their nonalcohol-dependent male siblings on sensation seeking and explicit gambling task (EGT). EGT is similar to the Iowa gambling task in administration, but varies from it as it involves a single outcome and provides unambiguous, explicit, and continuous feedback for the participants. Results and Conclusion: The results did not show any significant relationship between decision-making variables and sensation seeking. However, despite unambiguous, explicit, and continuous feedback, patients showed significantly poor decision-making as compared to the siblings of the P-ADS group. This study throws light on why people who are addicted to alcohol have difficulties in decision-making, despite knowing the adverse effects. PMID- 29456321 TI - Study of personality traits, individual coping resources, and their association in HIV-seropositive males. AB - Background: HIV infection is an unfortunate consequence of a defined set of behaviors. Individuals with continued high-risk behavior either due to personality factors or due to maladaptive coping skills have higher viral loads and morbidity. Research has shown significant interactions between less effective coping styles and personality factors. Aim: This study aimed to evaluate personality traits, coping skills, and their association in male HIV-seropositive cases. Materials and Methods: This was a cross-sectional study, conducted on 86 patients. Informed consent and sociodemographic details, by a structured questionnaire, were obtained. Scales pertaining to personality factors and coping were applied. Statistical analysis was done by SPSS 16. Results: Neuroticism, extraversion, and conscientiousness traits were in the average range. Scores on openness and agreeableness were below average. The results pertaining to coping showed an overall mean score of 50.78, with the highest on physical domain and then on the philosophical domain, the lowest was in social domain. The research sample perceived their coping resources as average. Neuroticism was negatively related to all the coping styles. Extraversion showed relation with physical, emotional, social, and philosophical scales. Openness was related to philosophical and emotional scales. Agreeableness correlated with all domains of coping except the social. Conscientiousness correlated significantly with all the domains of coping. Conclusion: The various personality traits associated with male HIV-seropositive patients were identified and various coping resources used by these were also delineated. Further, the association among them was identified which can help in primary prevention and mental health professionals to have a targeted approach for counseling. PMID- 29456322 TI - Images of psychiatry: Attitude survey of teaching medical specialists of India. AB - Context: Attitude of teaching medical specialists shapes those of future doctors. Region-specific data on teaching medical specialists' attitudes toward psychiatry (ATP) are lacking from India. Aims: This study aimed to assess the attitudes of teaching medical specialists toward psychiatry and its association with sociodemographic profile and career stage. Settings and Design: This is a cross sectional descriptive survey. Materials and Methods: Attitude towards psychiatry (ATP) was assessed from 188 specialists from All India Institute of Medical Sciences (AIIMS) Bhubaneswar and AIIMS Jodhpur using modified ATP scale-30. Statistical Analysis: Descriptive statistical analysis was done using SPSS version 16.0. Associations of ATP with sociodemographic status, career stage, and family history of psychiatric illness were done using logistic regression analysis. Results: Overall response rate was 81.68%, and gender (confidence interval [C.I.]: 2.026-7.410, P = 0.000) and super-specialization (C.I.: 2.167 19.479, P = 0.021) were independent significant predictors for difference in attitudes. Female gender and super-specialization were associated with better attitudes. Ninety percent of participants had favorable attitude toward psychiatric illness. Four-fifth felt psychiatric patients to be as human as other patients and found psychiatric treatments effective. More than half felt that psychiatry does not stand among the three most exciting specialties and psychiatrists get less work satisfaction. Only one third said that they would have liked to be a psychiatrist. Conclusions: Attitudes were favorable toward patients and psychiatric interventions whereas unfavorable toward psychiatry as a discipline. PMID- 29456323 TI - Cross-sectional study of anxiety symptoms in students in preexamination period. AB - Background: Preexamination period is an exceptionally stressful time for schoolgoing children and adolescents, and the propensity of having anxiety symptoms increases. Aim: This study aimed to assess the presence of anxiety symptoms in students in preexamination period. Materials and Methods: The study was carried on 619 children from Class VIII to XI. All of them were given a structured questionnaire for sociodemographic profile and Screen for Child Anxiety Related Emotional Disorders questionnaire. Association of various variables with presence of anxiety symptoms was assessed. Statistics was analyzed with SPSS version 17.0 software. Results: Totally 170 children (27.5%) had anxiety symptoms, similarly the various subgroups had increased frequency compared to the known prevalence in this age group. Age, years spent in the current school, living with parents, presence of domestic stressors, and grade deterioration, all were significantly associated with increased frequency of these symptoms. Similarly, association with various subgroups is described. Conclusion: This study attempts to give evidence of increased anxiety symptoms, during preexamination phase, compared to the reported prevalence in this age group, and thus to address this becomes imperative which will improve their performance and also the mental health preventing distress along with psychological and behavioral problems. PMID- 29456324 TI - Stress and suicidal ideation among adolescents having academic difficulty. AB - Background and Objectives: Academically typically achieving adolescents were compared with students having academic difficulty on stress and suicidal ideas. Materials and Methods: In a cross-sectional study, 75 academically typically achieving adolescents were compared with 105 students with academic difficulty and 52 students with specific learning disability (SLD). Academic functioning was assessed using teacher's screening instrument, intelligence quotient, and National Institute of Mental Health and Neurosciences index for SLD. Stress and suicidal ideas were assessed using general health questionnaire, suicide risk-11, and Mooney Problem Checklist (MPC). Appropriate statistical methods were applied. Results: Three groups were comparable on age, gender, mother's working status, being only child, nuclear family, self-reported academic decline, and type of school. About half of adolescents reported psychological problems on General Health Questionnaire (mean score >3 in all the groups). Academically typically achieving adolescents showed higher stressors in peer relationships, planning for future and suicidal ideation compared to adolescents with academic difficulty. Adolescents face stress regarding worry about examinations, family not understanding what child has to do in school, unfair tests, too much work in some subjects, afraid of failure in school work, not spending enough time in studies, parental expectations, wanting to be more popular, worried about a family member, planning for the future, and fear of the future. Significant positive correlation was seen between General Health Questionnaire scores and all four subscales of MPC. Suicidal ideas showed a negative correlation with MPC. Interpretations and Conclusions: Adolescents experience considerable stress in multiple areas irrespective of their academic ability and performance. Hence, assessment and management of stress among adolescents must extend beyond academic difficulties. PMID- 29456325 TI - A study on different forms of intelligence in Indian school-going children. AB - Introduction: Most definitions of intelligence focus on capabilities that are relevant to scholastic performances. However, there are seven forms of intelligences. There is a lack of data on multiple intelligences in Indian children. Hence, this study was conducted to assess different forms of intelligences in students and compared these diverse intelligences with intelligence quotient (IQ) scores. Materials and Methods: In this cross-sectional observational study, we recruited 1065 school children between the age of 12 and 16 years from two government and 13 private schools in five towns, six cities, and two villages across India. All the children were administered multiple intelligences questionnaire by Armstrong, consisting of thirty true/false types of questions to assess the intelligences of a child in seven domains including linguistic skills, logical/mathematical abilities, musical skills, spatial intelligence, bodily-kinesthetic skills, intrapersonal intelligence, and interpersonal intelligence. IQ scores were assessed by Ravens Standard Progressive Matrices. Results: We found that different students possessed different forms of intelligences and most students had more than one forms of intelligence. Of seven forms of intelligence, only three forms of intelligence such as logical/mathematical, musical, and spatial were positively correlated with the IQ score. Conclusions: Even in the children with low IQ, many students had other forms of intelligences. The IQ scores correlated with only logical/mathematical, spatial, and musical intelligence. Hence, tapping the intelligences of students can help enhance their learning process. Our curriculum should have an amalgamation of teaching for all kinds of intelligences for maximum productivity. PMID- 29456326 TI - Effect of type of schooling and gender on sociability and shyness among students. AB - Background: Sociability and shyness are orthogonal personality traits, wherein both are characterized by varying behavioral and psychophysiological correlates. Shyness should not be equated with the lack of sociability, as shyness relates to discomfort that occurs in the presence of others and sociability is identified with an individual's preference for being with others rather than alone. Objectives: The objective of this study was to examine the effect of type of schooling on sociability and shyness among students and to study the gender differences between sociability and shyness among students. Methodology: The sample comprised 210 students from both private and government schools situated in Delhi. Data were collected using Eysenck Personality Profiler for measuring sociability and Revised Cheek and Buss Shyness Scale. Results and Conclusion: The results obtained from ANOVA revealed that government school students were observed to be more sociable as compared to private school students. On the other hand, private school students were found to be more shy as compared to government school students. Females were observed to be more shy as compared to males. In addition, significant interactive effect was observed for sociability when school and gender were taken altogether. PMID- 29456327 TI - Study of insomnia in rotating shift-workers. AB - Background: Shift-workers commonly suffer from insomnia. This study evaluates different domains of insomnia. Aim: This study was aimed to study sleep and insomnia in rotating shift-workers and compare with day-workers. Materials and Methods: This was case-control study. The sleep of rotating shift-workers is compared with day workers using Athens Insomnia Scale. Results: Rotating shift workers had significantly higher scores on Athens insomnia scale on domains of initial, intermediate and terminal insomnia than day workers. Duration and quality of sleep and sense of well-being are lower in rotating shift-workers. Rotating shift-workers also experienced more day-time sleepiness than day workers. However, there was no difference in perceived physical and mental functioning between the two groups. Conclusion: Individuals working in rotating shifts for more than 15 days have significantly higher prevalence of insomnia than day-workers. PMID- 29456328 TI - Prevalence of depression and its relation to stress level among medical students in Puducherry, India. AB - Background: Currently, depression among medical students is an important health issue at the global level. There is also a paucity of information on its relation to the stress level. Objective: The aim of this study is to assess the prevalence of depression and its relation to stress level and other factors among medical students. Materials and Methods: A cross-sectional study was conducted among medical students at a tertiary care medical institution in Puducherry, coastal south India. Beck Depression Inventory Scale was used for screening of depression and Cohen's Perceived Stress scale to assess perceived stress level. Data on associated factors were collected by self-administered questionnaire. Results: The overall prevalence of depression was found to be 48.4% (215/444). According to the cutoff scores, 229 (51.6%) students scored as normal (0-9), 149 (33.6%) as mild (10-18), 60 (13.5%) as moderate (19-29), 3 (0.7%) as severe (30-40), and 3 (0.7%) students scored as very severe (>40) depression. Depression was significantly less among those with mild stress (adjusted odds ratio [OR] = 0.010) and moderate stress level (adjusted OR = 0.099) compared to severe stress level and those without interpersonal problems (adjusted OR = 0.448). Conclusion: Depression is more common among medical students. Stress coping mechanisms and improvement of interpersonal relationship may help to reduce depressive symptoms among medical students. PMID- 29456329 TI - A descriptive study of behavioral problems in schoolgoing children. AB - Background: Behavioral problems among schoolgoing children are of significant concern to teachers and parents. These are known to have both immediate and long term unfavorable consequences. Despite the high prevalence, studies on psychiatric morbidity among school children are lacking in our country. Materials and Methods: Five hundred children aged 6-18 years were randomly selected from a government school in Kanpur, Uttar Pradesh, and assessed for cognitive, emotional, or behavioral problems using standardized tools. Results: About 22.7% of children showed behavioral, cognitive, or emotional problems. Additional screening and evaluation tools pointed toward a higher prevalence of externalizing symptoms among boys than girls. Conclusion: The study highlights the importance of regular screening of school children for preventive as well as timely remedial measures. PMID- 29456330 TI - A study of individuals with intentional self-harm referred to psychiatry in a tertiary care center. AB - Background: Intentional self- harm (ISH) is one of the commonest yet neglected entities of Consultation liaison Psychiatry. More researches in the field of ISH are needed to effectively manage this problem. Aim: To study the socio demographic and clinical profile of subjects of ISH referred to Psychiatry in a tertiary care hospital. Materials and Methods: All subjects of ISH referred to department of Psychiatry, of a tertiary centre, on specified days were recruited in to the study after obtaining an informed consent. Socio-demographic details, details of psychiatric assessment were documented using a semi structured proforma. Appropriate management was done. Results: Forty one subjects were included in the study. About two third of them belonged to the age group of 18 to 35 years. 56% of them were males, and 71% were married. House wives and students formed a significant proportion of sample. Most common method of ISH was self poisoning. About two third of the patients had no diagnosable psychiatric illness. Interpersonal conflicts with family members (47%), conflicts with spouse (22%), broken emotional relationship (18%) were common causes for impulsive acts of ISH. Conclusions: ISH is common amongst young, married males. About two third of those who attempt ISH have no diagnosable psychiatric illness, in rest, neurotic stress related disorders, personality disorders and substance use disorders were predominant. PMID- 29456331 TI - Valproate induced hyperammonemic encephalopathy treated by haemodialysis. AB - Valproate (VPA)-induced hyperammonemic encephalopathy is an unusual, but serious, adverse effect of divalproex sodium (DVPX) treatment and if untreated can lead to raised intracranial pressure, seizures, coma, and eventually death. It can, however, be reversed if an early diagnosis is made. It is therefore extremely important to recognize it and discontinue DVPX treatment. Our patient developed sudden deterioration of sensorium, drowsiness, lethargy, and later severe comatose state after few days of starting DVPX with high levels of serum ammonia despite therapeutic levels of VPA and normal liver function test. He responded to hemodialysis, cerebral decongestants, and other intensive supportive measures. PMID- 29456332 TI - Clozapine-induced hypertension: A case report and review of literature. AB - There are very few reports which suggest an association between clozapine and hypertension. We report a case in which a direct link of initiation of clozapine to development of hypertension which required pharmacological intervention. A 32 year-old male who did not have any history of hypertension and had normal blood pressure at the baseline developed high blood pressure (i.e., 150/90 mmHg) while on clozapine 100 mg/day. Reduction of the dose of clozapine to 75 mg/day led to the return of blood pressure to baseline, with increase in blood pressure to 150/90 mmHg on increasing the dose of clozapine again, requiring tablet atenolol 50 mg/day for normalization of blood pressure with concomitant continuation of atenolol. Later, clozapine was increased to 350 mg/day, with no recurrence of raise in blood pressure. After 6 months, tablet atenolol was stopped with no evidence of hypertension in follow-up. To conclude, this case report suggests that clozapine can rarely lead to hypertension during the initial phase of treatment. PMID- 29456333 TI - Selfie use: The implications for psychopathology expression of body dysmorphic disorder. AB - Preoccupation with a body part can lead to indulgence in various forms of coping behavior. Users are frequently using technology as well as selfie to overcome their anxiety to relate to a body part as well as get approval from other online users. The present case highlights the excessive use of selfie to manage the distress-related body dysmorphic disorder (BDD). Psychiatric interview and assessment tools were used to elicit information about BDD, technology use, and affective states. Repeated use of selfie has been thought to manage the distress associated with appearance. It implies the need for screening excessive use of technology as comorbid condition and psychoeducation for promotion of healthy use of technology.

AB - Objectives: Patients with stroke are faced with gait, balance, and fall difficulties which could impact on their community reintegration. In Nigeria, community reintegration after stroke has been understudied. The objective of this study was to evaluate the predictors of community reintegration in adult patients with stroke. Materials and Methods: Participants were 91 adult patients with stroke. Gait variables, balance self-efficacy, community balance/mobility, and fall self-efficacy were assessed using Rivermead Mobility Index, Activities specific Balance Confidence Scale, Community Balance and Mobility Scale, and Falls Efficacy Scale-International respectively. Reintegration to Normal Living Index was used to assess satisfaction with community reintegration. Pearson Product-Moment Correlation Coefficient was used to determine the relationship between community reintegration and gait spatiotemporal variables, balance performance, and risk of fall. Multiple regression analysis was used to determine predictors of community reintegration (P <= 0.05). Results: There was significant positive relationship between community reintegration and cadence (r = 0.250, P = 0.017), functional mobility (r = 0.503, P = 0.001), balance self-efficacy (r = 0.608, P = 0.001), community balance/mobility (r = 0.586, P = 0.001), and duration of stroke (r = 0.220, P = 0.036). Stride time (r = -0.282, P = 0.073) and fall self-efficacy (r = 0.566, P = 0.001) were negatively correlated with community reintegration. Duration of stroke, balance self-efficacy, community balance/mobility, and fall self-efficacy (52.7% of the variance) were the significant predictors of community reintegration. Conclusion: Community reintegration is influenced by cadence, functional mobility, balance self efficacy, community balance/mobility, and duration of stroke. Hence, improving balance and mobility during rehabilitation is important in enhancing community reintegration in patients with stroke. PMID- 29456338 TI - Study of Knowledge, Attitude, and Practice in Participants with Regular Intake of Lathyrus, But No Spastic Paraparesis. AB - Background and Purpose: Neurolathyrism is now a disease of the past and also the causative agent, Lathyrus sativus (Khesari Pulse or keerai in Local Hindi and Bhojpuri language) has now been proven to be harmless and has become part of the usual diet. Materials and Methods: The population at risk was screened and studied for demography, economic status, knowledge about Khesari pulse, awareness about so-called harmful effects of Khesari pulse intake in humans, and the effects of ban of Khesari pulse on the population which is using Lathyrus (Khesari) as a major source of pulse since the past 4 years through a questionnaire of three pages. Results: Nearly 97% of total screened population totally fed on Khesari pulse as their major source of food and we did not found a single case of primary walking difficulty. We did find three cases of poststroke paralysis, a case of post-GBS lower limb weakness, and a case of recurrent myelitis as a part of questionnaire-based study and then followed by personally examining the patients to confirm the diagnosis. Conclusion: Khesari pulse if consumed in smaller quantities as a part of a normal mixed diet, its nutritional values can be optimally utilized. PMID- 29456339 TI - Retrospective Analysis of Arthrodesis from Various Options after Anterior Cervical Discectomy. AB - Introduction: Anterior cervical discectomy is a surgical procedure performed to treat a herniated/degenerated disc in the cervical region. There have been various studies comparing arthrodesis rates among various procedures. Our patients belonged to varied socioeconomic background and underwent anterior cervical microdiscectomy without/with instrumentation. Aim: The present study was performed to study and compare the arthrodesis rates in the patients operated for anterior cervical microdiscectomy with and without fusion/instrumentation procedures at our institution. Materials and Methods: This is a retrospective study performed at Vydehi Institute of Medical Sciences and Research Centre, Bengaluru. Pre- and post-operative X-rays were assessed in 96 patients who had undergone anterior cervical discectomy with/without fusion from June 2012 to June 2015. Radiographic arthrodesis was assessed in all patients. An arbitrary grading was designed by us and categorized into Grade I to IV. The criteria considered for adequate arthrodesis in this study were: (a) <2 degrees movement on dynamic X-rays, (b) restored disc space height (+/-2 mm accepted), and (c) evidence of solid bone mass around disc space. Arthrodesis was categorized as Grade I if all the above 3 criteria on X-rays was fulfilled, Grade II if any 2 of the criteria was fulfilled, Grade III if any 1 of the criteria was fulfilled, and Grade IV when pseudoarthrosis/none of the criteria was fulfilled. Grade I arthrodesis was noted in about 79 patients (82.2%), Grade II in 14 patients, and only 3 patients had Grade III arthrodesis. There were no patients with absent arthrodesis/pseudoarthrosis. Results: Satisfactory arthrodesis was noted in 82% of the total patients, with patients undergoing fusion +/- instrumentation procedure having better results. Conclusions: Arthrodesis by an interbody graft/implant with/without plating increases chances of success as compared to anterior cervical discectomy alone. Patients should be motivated for any of the available options for fusion/instrumentation. PMID- 29456340 TI - Acute Febrile Encephalopathy in Children: A Prospective Study of Clinical Features, Etiology, Mortality, and Risk Factors from Western India. AB - Introduction: Acute febrile encephalopathy (AFE) in children is a medical emergency and could be a manifestation of many systemic and central nervous system pathologies. The clinical features of AFE are nonspecific and etiological spectrum variable depending on the studied population. Materials and Methods: A prospective, observational study was carried out including children aged between 1 month and 12 years with AFE admitted to the Pediatric Intensive Care Unit of a tertiary care hospital in Western India. The primary objective was to assess the clinical presentation and etiology of AFE while the secondary objectives were to correlate the clinical and etiological findings and to determine the risk factors associated with mortality. Results: Out of the ninety children with AFE included in this study, male:female ratio was 1.2:1; most of them were aged between 1 and 5 years and came with a history of < 7 days (82.2%). All of them had altered sensorium, about 2/3rd had seizures and 47.8% having a Glasgow Coma Score (GCS) <8. Etiology remained elusive in about 40% of the cases, and viral infections were the most common among the ones with an identifiable cause. A variety of morbidity (shock, disseminated intravascular coagulopathy, respiratory failure, etc.) and high mortality (40%) was observed with risk factors associated with mortality being GCS < 8, the presence of raised intracranial pressure, shock, and respiratory failure. Conclusion: AFE, though a rare diagnosis in children, is associated with significant morbidity and high mortality in a developing country like India. PMID- 29456341 TI - Using of Fresh Cadaveric Cow Brain in the Microsurgical Training Model for Sulcal Cisternal and Fissural Dissection. AB - Objective: The aim of this experimental study was to evaluate the feasibility of using fresh cadaveric cow brain as in a training model for microsurgical dissection of sulcus, cisterns, and fissure. Methods: Experimental microneurosurgical activities in this study were performed under the operating microscope. Bilateral sylvian cisterns, interhemispheric fissure, and hemispheric sulcus of the fresh cadaveric cow brain were used as an interested area for this experimental study. The dissection was continued reaching down to the floor of the cistern and total dissection of the middle cerebral artery inside the cisternal space. The suitability of a cow brain as a training model for sylvian fissure microdissection was evaluated as three groups; bad, good, and perfect. Results: Ten uncovered fresh cadaveric cow brains were used in this experimental feasibility study. The suitability of the experiment for training model was evaluated as bad in (1) 10% of the fresh cadaveric cow brains. The suitability was found as good in (6) 60% of the procedures. In the remaining (3) 30% of the brain dissection, the suitability of the experiment was evaluated as perfect. Conclusion: In conclusion, performing the sulcal, cisternal, and fissural dissection and protecting the neural and vascular tissue from the mechanical bruising effect of metallic microsurgical instruments are feasible as shown in this study. We believe that this training model will contribute to the practical micro-neurosurgery. Additionally, it provides adequate performance for the microsurgical intervention.

Discussion: There is a spectrum of immune-mediated neuropathy which varies in clinical course, response to treatment, etc., Small percentage of uncommon cases are seen. In this group, mortality was nil and morbidity was minimal. Conclusion: Immune-mediated neuropathies are treatable and hence should be diagnosed early for good quality outcome. PMID- 29456343 TI - Factors Influencing Institutional-Based Pediatric Rehabilitation Services among Caregivers of Children with Developmental Delay in Southwestern Rajasthan. AB - Context: A limited number of caregivers of children with developmental delay access rehabilitation facilities in India. The study explored utilization of rehabilitation services at a tertiary care setup in southwestern Rajasthan and various factors influencing it. Aims: The aim of this study is to explore rehabilitation service utilization among children with developmental delay at a tertiary care setup and to ascertain factors that influence this pattern. Settings: This study was conducted at the department of physical medicine and rehabilitation at tertiary care setup. Design: This was an observational study. Subjects and Methods: Children with developmental delay who were advised institutional-based rehabilitation were identified over span of 1 year. Those who failed to return for rehabilitation after the first visit were interviewed telephonically. The interview had semi-structured open-ended questions about their reasons for inability to avail services. Statistical Analysis: SPSS statistics 22 was used for descriptive analysis and correlation of variables. Results: Of 230 children with developmental delay visiting department in 1-year duration, 48 took regular rehabilitation. Parents of 129 children with complete records were asked regarding discontinuation. Factors cited by majority were long distance from institute and service at hospital. Other reasons for discontinuation were related to belief system, family issues, time issues, socioeconomic factors, etc. Socioeconomic status was significantly associated with parental education (C = 0.488, P = 0.000) and financial issues. Location of family had significant association with long distance (C = 0.315, P = 0.000), parental education (C = 0.251, P = 0.003), and belief system (C = 0.265, P = 0.002). Conclusions: Distance from institute and quality of hospital service determined rehabilitation service use at a tertiary institute. Other factors such as socioeconomic status, family support, and social belief system must also be addressed while delivering institutional rehabilitation to children. PMID- 29456344 TI - Hansen's Neuritis Revisited - A Clinicopathological Study. AB - Introduction: Leprosy affecting the nerve solely or with concomitant skin lesions is not an uncommon condition in clinical practice. It is responsible for extensive morbidity and often poses a diagnostic challenge. This study aims to highlight the clinicopathological features of Hansen's neuritis (HN). Materials and Methods: In this retrospective study, cases of histologically diagnosed HN, from January 2010 to July 2017, were reviewed in the light of clinical features, treatment history, and outcome. Results: There were 18 cases of HN which accounted for 3.97% of total nerve biopsy samples (n = 453) and 0.02% of total histopathology samples (n = 81,013). The male: female ratio was 5:1 in the cases of HN. Age range was 20-79 years with a mean age of 42.4 years (standard deviation: +/-14.03). Among the HN cases, there were 13 cases of pure neuritic leprosy (61.1%). Mononeuritis multiplex was the most common finding in the nerve conduction study. Six (33.3%) cases exhibited histological features of borderline tuberculoid leprosy, followed by five (27.8%) cases of mid-borderline features, three (16.7%) cases each of borderline lepromatous and burnt-out HN, and one (5.6%) case of polar tuberculoid leprosy. Lepra bacilli were detected on Fite Faraco stain in 44.4% cases. Conclusion: Diagnosis of HN depends on astute search for skin lesions, nerve thickening or tenderness, sensory or motor symptoms, histopathological examination, and demonstration of lepra bacilli.

AB - Background: Physical injury has been associated with the development of several psychopathological manifestations. Less is known about the use of psychiatric medication in those patients. Objectives: This study aimed to explore the use of psychiatric medication by patients been admitted in a rehabilitation center in a tertiary care teaching hospital and to inquire for the correlations of such drug administration. Materials and Methods: The sample consisted of 127 patients who had been admitted to a rehabilitation center, being in the postacute phase of their condition during a 2-year period. Patients' medical records were searched for the demographic and clinical information. Results: Analysis was performed for 118 patients, mostly men (62.7%) with the mean age of 57.5 years. About 43.2% of patients (n = 51) were referred for psychiatric consultation, and 39.8% (n = 47) were prescribed a psychiatric drug. Traumatic brain injury was the diagnosis, positively correlated to referral. Twenty-seven out of the 67 nonreferred patients (40.3%) were prescribed psychiatric regimens by physicians. Nearly 38.1% of patients were diagnosed with a psychiatric disorder by the consultation Liaison psychiatric service. Conclusions: In a rehabilitation center, psychiatric drug administration is common practice and drugs may be prescribed by the center's physicians and by psychiatrists. Such a drug prescription was found to be correlated to referral to the consultation-Liaison psychiatric service. PMID- 29456346 TI - The Effects of Posterior Talar Glide and Dorsiflexion of the Ankle Plus Mobilization with Movement on Balance and Gait Function in Patient with Chronic Stroke: A Randomized Controlled Trial. AB - Background: This study was to evaluate the effects of weight-bearing-based mobilization with movement (WBBMWM) on balance and gait in stroke patients. Methods: Thirty stroke patients participated in this study. All individuals were randomly assigned to either WBMWM group (n = 15) or weight-bearing with placebo mobilization with movement group (control, n = 15). Individuals in the WBMWM group were trained for 10 glides of 5 sets a day, 5 times a week during 4 weeks. Furthermore, individuals in the control group were trained for 10 lunges of 5 sets a day, 5 times a week during 4 weeks. All individuals were measured weight bearing lunge test (WBLT), static balance ability, timed up and go test (TUG), and dynamic gait index (DGI) in before and after intervention. Results: The result showed that WBBMWM group and control group had significantly increased in WBLT, postural sway speed, total postural sway path length with eyes open and closed, TUG and DGI (P < 0.05). In particular, the WBMWM group showed significantly greater improvement than control group in WBLT, static balance measures, TUG, and DGI (P < 0.05). Conclusion: Therefore, WBMWM improved ankle range of motion, balance, and gait in stroke patients. These results suggest that WBBMWM is feasible and suitable for individuals with a stroke. PMID- 29456347 TI - The Evolving Pattern and Outcome of Stroke at Moderate Altitude. AB - Background: The people residing in hills of this Sub-Himalayan region traditionally have a distinct lifestyle involving high level of physical activity. However, increased urbanization in the last two decades has led to changes in lifestyle of people. The present study was an endeavor to document changes in the pattern of stroke in people residing at moderate altitude. Aim: This study was aimed to study the evolving trends in clinical profile, risk factors, and outcome at 3 months in hospitalized patients of stroke in a Tertiary Care Hospital situated at moderate altitude. Setting and Design: This prospective, observational study was carried out in a Tertiary Care Hospital, situated at 2000 m mean sea level, from July 2014 to June 2015 in Sub-Himalayan region of India. Methods: The clinical features and risk factors profile of 235 patients of stroke consecutively admitted in hospital were analyzed, and findings were expressed in percentage. The profile was compared with a study conducted at this institute 15 years back. The outcome of patients at 3 months in terms of modified Rankin Scale >3 (mRS) and Barthel Index <60 (BI) was also studied. Results: The occurrence of stroke as a cause of hospitalization was decreasing. Ischemic stroke was noted in 74%, and 26% had hemorrhagic stroke (HS). There was male predominance (58%), but affliction of females with stroke increased from 34% to 42%. The altered sensorium (P = 0.00) and neurological weakness (P = 0.024) were significantly associated with poor outcome in stroke. The occurrence of hypertension, diabetes mellitus, and coronary artery disease increased but smoking decreased among indoor patients of stroke in the last 15 years. Poor outcome of 203 patients at 3 months follow-up in terms of mRS >3 was 79 (IS-47, HS-32) but in term of BI, 63 (IS-32, HS-31) had poor outcome. Overall HS had poorer outcome. Age >70 years, female sex, altered sensorium, hypertension, and diabetes mellitus, were observed as poor prognostic factors, but the association was significant with advanced age, headache, and altered sensorium. Conclusion: The occurrence of stroke decreased among hospitalized patients. Hypertension, diabetes mellitus, and coronary artery disease increased but smoking decreased among patients of stroke. PMID- 29456348 TI - Efficacy of Dexmedetomidine as an Adjuvant to Local Anesthetic Agent in Scalp Block and Scalp Infiltration to Control Postcraniotomy Pain: A Double-Blind Randomized Trial. AB - Context: Scalp infiltration and scalp block are being used to manage postcraniotomy pain. Dexmedetomidine has been successfully used as an adjuvant in regional anesthesia. The study was intended to compare whether addition of dexmedetomidine prolonged the duration of analgesia as well as to compare the two techniques. Aims: The primary objective was to assess whether addition of dexmedetomidine to bupivacaine prolonged the duration of analgesia. The secondary objective was to compare between scalp nerve block and scalp infiltration as techniques for pain relief. Settings and Design: The randomized control study was conducted in a tertiary care center from November 2013 to October 2014. Materials and Methods: A total of 150 American Society of Anesthesiologists Physical Status I-II patients, aged 18-70 years undergoing elective craniotomy were included. Patients were randomized into three groups of 50 patients, i.e., Group BI (bupivacaine infiltration), Group BDI (bupivacaine and dexmedetomidine infiltration), and Group BDNB (bupivacaine and dexmedetomidine scalp nerve block). Patient's pain score, pain-free interval, rescue analgesic requirement, and hemodynamic and respiratory parameters were noted for 48 h. Patients were followed up at 1 and 3 months to assess postcraniotomy pain. Results: Pain-free period was significantly longer in Group BDNB than Groups BDI and BI (P < 0.0001) and pain control was better in dexmedetomidine containing groups than in bupivacaine group (BI) (P < 0.0001). The rescue analgesic requirement was significantly lower in Group BDNB and Group BDI compared to Group BI. Conclusion: The addition of dexmedetomidine (1 MUg/kg) to bupivacaine prolonged the pain-free period. Scalp nerve block is a superior technique than scalp infiltration. PMID- 29456349 TI - Effects of Crystalloid Preloading (20 ml/kg) on Hemodynamics in Relation to Postural Changes in Patients Undergoing Neurosurgical Procedures in Sitting Position. AB - Background: Hemodynamic disturbances are common during positioning the patients from supine to sitting for neurosurgical procedures. The reported incidence of hypotension varies from 5% to 32%. The aim of the study was to study the effect of crystalloid preloading on hemodynamic parameters during positioning the patient from supine to sitting position. Materials and Methods: In this prospective observational trial, 20 patients were enrolled. Two patients had a patent foramen ovale on transesophageal echocardiography and were excluded from the study. All the patients received 20 ml/kg of crystalloid (Ringer's lactate) before initiation of positioning. Physiological hemodynamic parameters such as heart rate, mean arterial pressure, central venous pressure, cardiac output (CO), stroke volume variation (SVV), cardiac index (CI), stroke volume (SV), and maximum and minimum inferior vena caval diameter (IVCD) were recorded after induction, during positioning at 30 degrees , 60 degrees inclination of the operating table and after the final sitting position. Results: Hemodynamic parameters were well maintained during positioning of the patients from supine to sitting position. Crystalloid preloading prevented the hypotension during positioning. There were no significant changes in hemodynamic parameters such as CO, SVR, SVV, CI, and SV. We did not find any correlation with changes in IVCD with changes in CO. Conclusion: A volume of 20 ml/kg of crystalloid preloading before positioning the patient from supine to sitting position maintains the hemodynamic stability and avoids the vasopressor requirement. PMID- 29456350 TI - Recurrent Glioblastomas Exhibit Higher Expression of Biomarkers with Stem-like Properties. AB - Background: Despite advances in the treatment of glioblastoma (GBM), the prognosis of patients continues to remain dismal. This unfavorable prognosis is mainly attributed to the tumor's propensity for progression and recurrence, which in turn is due to the highly aggressive nature of the persisting GBM cells that actively egress from the main tumor mass into the surrounding normal brain tissue. Such a recurrent tumor described to have a more malignant potential is highly invasive and resistant to current therapies, probably due to increased stemness and preferential selection of therapy-resistant clones of tumor cells. However, there is a paucity of literature on the expression of biomarkers in the recurrent GBM tumors that could have a role in conferring this aggressiveness. Aim: To identify the differences in the expression pattern of selected biomarkers in paired tissue samples of GBM. Material and Methods: A retrospective study on 30 paired samples of GBM (newly diagnosed/primary and recurrent) archived in the Department of Neuropathology, NIMHANS (2006-2009), was carried out. After obtaining clinical and demographic details, tumors were characterized histomorphologically and immunohistochemically on formalin-fixed paraffin embedded tissues with reference to expression of biomarkers such as p53, epidermal growth factor receptor (EGFR), insulin-like growth factor binding protein 3 (IGFBP-3), sex determining region Y-box 2 (SOX2), and topoisomerase 2 A (Top2A). The results were statistically analyzed. Results: It was observed that while p53 and IGFBP-3 expression remained unaltered in paired samples, a significant increase in the expression of EGFR (P < 0.01) was noted in the recurrent tumors. Among the other biomarkers, SOX2 expression was higher in the recurrent tumors when compared to the primary tumors (P < 0.01). Conversely, the expression of Top2A was reduced in recurrent tumors (P = 0.05). Mild elevation in the expression of IGFBP-3 was observed in recurrent tumors but was not statistically significant. Conclusion: A significant increase in the expression of SOX2 in recurrent tumors probably indicates the presence of undifferentiated cells with stem-like properties in these tumors. EGFR is known to mediate SOX2 expression thereby resulting in stemness of the glioma cancer cells, which could further explain its overexpression in recurrent GBMs. Furthermore, a decreased expression of TOP2A observed in the recurrent tumors could probably be due to reduction in chemosensitivity to temozolomide, which has been shown in earlier studies. We also noted that p53 expression remained unaltered in the recurrent tumors when compared to the primary, suggesting the absence of preferential clonal expansion of p53 mutant cells following exposure to radiochemotherapy. Our study reiterates the fact that GBM recurrences are associated with molecular alterations that probably contribute to radiochemoresistance, increased invasiveness, therapeutic efficacy, and stemness. PMID- 29456351 TI - Quality of Sleep and Sleep Disorders in Patients with Parkinsonism: A Polysomnography Based Study from Rural South India. AB - Objective: The objective of this study is to study the quality of sleep, sleep disorders, and polysomnographic profile in Parkinsonism patients from rural areas and to correlate polysomnographic profile with the staging of disease and with sleep questionnaire. Materials and Methods: Between May 2014 and December 2015, 168 Parkinsonism patients were prospectively screened using sleep questionnaire; Epworth Sleepiness Scale (ESS), Pittsburgh Sleep Quality Index (PSQI), Parkinson Disease Sleep Score-2 (PDSS-2). Sixty patients underwent overnight polysomnography subsequently. Results: The mean age of 168 patients in the study was 65.3 +/- 12.8 years. The mean duration of Parkinsonism was 4.6 +/- 3.1 years. The mean ESS, PSQI and PDSS-2 were 12.4 +/- 3.2, 7.9 +/- 2.1 and 44.7 +/- 5.8, respectively. A total of 148 patients (88.1%) had poor quality sleep, which was reported only in 37 patients (22%). Excessive daytime sleepiness (80%) and insomnia (76.7%) were most common symptoms. Polysomnographic profile showed poor sleep efficiency (median interquartile range [IQR] 74.8% [17.8%-99.5%]), reduced slow wave sleep (median [IQR] 0% [0%-9.5%]), and reduced rapid eye movement [REM] sleep (median (IQR) 4.9% [0.1%-24.2%]). Sleep disorders in the study were sleep fragmentation (n = 60, 100%), obstructive sleep apnea syndrome (n = 40, 66.7%), central sleep apnea syndrome (n = 6, 10%), and periodic limb movement disorder (n = 52, 86.7%). Two patients had REM sleep behavioral disorder clinically. There was statistically significant positive correlation between staging of disease, sleep latencies, and sleep questionnaire. Conclusion: Sleep is impaired in majority of Parkinsonism patients which needs to be diagnosed early and managed effectively. Patient education and awareness programs in rural areas regarding sleep disorders in Parkinsonism are required for early diagnosis. PMID- 29456352 TI - Efficacy of Botulinum Toxin Type A in Trigeminal Neuralgia in a South Asian Cohort. AB - Introduction: The antinociceptive effect of botulinum toxin-A (BTX-A) in trigeminal neuralgia (TN) has been described. We evaluated effects of BTX-A in relieving pain in patients with refractory TN at National Hospital of Sri Lanka. Materials and Methods: Pain in patients with TN was assessed using a visual analog from 0 to 10. Three months after commencement of drug therapy with >=2 drugs including one first-line drug (carbamazepine/oxcarbazepine), pain scores were re-assessed. Twenty-two patients who did not report improvement of >=50% at 90 days' posttreatment were recruited. They were given adjunct BTX-A directly to the trigger point (if identified) or intradermal. Pain scores were assessed at 10, 20, 30, 60, and 90 days' posttreatment. Results: There was a statistically significant improvement in mean pain scores at 10, 20, 30, 60, and 90 days' posttreatment (5.59 [standard deviation (SD) = 2.7], 5.68 [SD = 2.6], 5.27 [SD = 3.2], 4.77 [SD = 3.7], and 5.32 [SD = 4.0]) compared to pre-BTX-A treatment (7.14, SD = 2.2). Percentage reduction in mean pain score ranged from 20.4% to 33.1%. Maximum response was at day 60 post-BTX-A (50% had >=50% reduction in pain). No significant difference was found in response with higher doses and injection strategy. Conclusion: Consistent statistically significant reductions in pain scores at the aforesaid intervals compared to pretreatment means that there is a place for BTX in refractory TN. PMID- 29456353 TI - The Utility of Preoperative ACTH/Cortisol Ratio for the Diagnosis and Prognosis of Cushing's Disease. AB - Purpose: Cushing's syndrome (CS) is a rare disease having diagnostic difficulties. Many diagnostic tests have been defined but none of these are diagnostic alone. Determination of the cause is another problem which sometimes requires more sophisticated and invasive procedures. Therefore, we aimed to evaluate the utility of pretreatment plasma adrenocorticotropic hormone (ACTH)/cortisol ratios in patients with confirmed endogenous CS for the diagnosis and differential diagnosis of CS. Materials and Methods: This retrospective evaluation included 145 patients with the diagnosis of CS, 119 patients with Cushing's disease (CD), and 26 patients with ACTH-independent CS (AICS), in a university hospital. Furthermore, 114 individuals in whom CS diagnosis was excluded with at least one negative screening test were enrolled to the study as control group. The clinical, laboratory, imaging, postsurgical pathologic records and also clinical follow-up data of all patients were evaluated. Results: The median basal ACTH/cortisol ratio of the patients with CD was significantly higher than AICS and controls. A cutoff ACTH/cortisol ratio >2.5 was found to be diagnostic for CD with 82% specificity and 63% sensitivity. Among CD group, patients with recurrent disease had higher preoperative ACTH levels and ACTH/cortisol ratio than patients with sustained remission. Furthermore, these patients had more invasive, atypical, and larger tumors. Conclusion: An ACTH/cortisol ratio >2.5 would be beneficial to diagnose CD together with other diagnostic tests. It is a simple test with no additional cost. Higher ratios might be related with larger, invasive, and atypical adenoma and also might be helpful to predict recurrence. PMID- 29456354 TI - Impact of Aging on Nerve Conduction Velocities and Late Responses in Healthy Individuals. AB - Background: Nerve conduction studies are performed to diagnose the disorders of the peripheral nervous system. The reference values for nerve conduction velocity (NCV) and late responses for different nerves considerably vary in different group and type of population. Physiological factors such as age, temperature, height, and gender affect the NCV. However, there are very few studies which show the age group at which these changes become significant. Aim and Objectives: The aim of the study was to establish the electrophysiological data of the specific age group at which changes in NCV as well as late responses of median common peroneal nerve and also see the late response in the form of F-waves and H reflex. Methodology: Study groups were divided into three categories based on the age: Group I (18-30 years) (n = 80), Group II (31-45 years) (n = 43), and Group III (46-60 years) (n = 27). Out of which, 93 patients were male and 57 were female. The NCVs were determined for median, common peroneal nerve (motor component and sensory component) along with late responses in the form of H reflex and F-waves. Results: The mean and standard deviation of median, ulnar, peroneal, and tibial nerve was studied for latencies, amplitude, and velocities for both sensory and motor components. Patients with older age had longer latencies, smaller amplitudes, and slower conduction velocities compared with the younger age group. The change with age was greater in sensory nerve conduction and late responses in all the peripheral nerves. Conclusions: Aging has a definite correlation with the NCV and late responses of different peripheral nerves. There is a need to have reference values with relation to age. PMID- 29456355 TI - Role of Yoga in Management of Substance-use Disorders: A Narrative Review. AB - Substance use disorders are comparable to chronic medical illnesses and have a chronic relapsing course. Despite being significant contributors to morbidity and mortality, limited treatment options exist. The current narrative review was aimed at providing an overview of yoga therapy in substance-use disorders and discuss the relevant methodological issues. Articles published in English language till May 2017 indexed with PubMed, PubMed central, and Google Scholar were searched using search terms "Yoga," "Substance use," "Drug dependence," "Nicotine," "Tobacco," "Alcohol," "Opioids," "Cannabis," "Cocaine," "Stimulants," "Sedative hypnotics," "Inhalants," and "Hallucinogens" for inclusion in the review. A total of 314 studies were found fulfilling the stated criteria. Out of which, 16 studies were found to fulfill the inclusion and exclusion criteria and 12 were randomized control trials. The majority of studies were available on the role of yoga in management of nicotine dependence. Sample size of these studies ranged from 18 to 624. The majority of studies suggested the role of yoga in reducing substance use as well as substance-related craving (especially in nicotine-use disorders) in short term. However, more studies are required for demonstrating the long-term effects of yoga therapy in substance-use disorder. PMID- 29456356 TI - The Current State of Rural Neurosurgical Practice: An International Perspective. AB - Introduction: Rural and low-resource areas have diminished capacity to care for neurosurgical patients due to lack of infrastructure, healthcare investment, and training programs. This review summarizes the range of rural neurosurgical procedures, novel mechanisms for delivering care, rapid training programs, and outcome differences across international rural neurosurgical practice. Methods: A comprehensive literature search was performed for English language manuscripts with keywords "rural" and "neurosurgery" using the National Library of Medicine PubMed database (01/1971-06/2017). Twenty-four articles focusing on rural non neurosurgical practice were included. Results: Time to care and/or surgery and shortage of trained personnel remain the strongest risk factors for mortality and poor outcome. Telemedicine consults to regional centers with neurosurgery housestaff have potential for increased timeliness of diagnosis/triage, improved time to surgery, and reductions in unnecessary transfers in remote areas. Mobile neurosurgery teams have been deployed with success in nations with large transport distances precluding initial transfers. Common neurosurgical procedures involve trauma mechanisms; accordingly, training programs for nonneurosurgery medical personnel on basic assessment and operative techniques have been successful in resource-deficient settings where neurosurgeons are unavailable. Conclusions: Protracted transport times, lack of resources/training, and difficulty retaining specialists are barriers to successful outcomes. Advances in telemedicine, mobile neurosurgery, and training programs for urgent operative techniques have been implemented efficaciously. Development of guidelines for paired partnerships between rural centers and academic hospitals, supplying surplus technology to rural areas, and rapid training of qualified local surgical personnel can create sustainable feed-forward programs for trainees and infrastructural solutions to address challenges in rural neurosurgery. PMID- 29456357 TI - Role of Exclusive Breastfeeding in Conferring Protection in Children At-Risk for Autism Spectrum Disorder: Results from a Sibling Case-control Study. AB - Background: Gut microflora influences neural development through complex mechanisms. Feeding practices, especially breastfeeding influence gut microbiome and thereby play a pivotal role in immune and neural development. Current understandings of the role of healthy distal gut microflora in the development of immune and neural systems provide insights into immunological mechanisms as one of the possible etiologies in autism spectrum disorder (ASD). Studies have shown that optimal breastfeeding is associated with lower odds of being at-risk for ASD and children with ASD are suboptimally breastfed. Methods: The feeding practices of children with ASD (n = 30) was compared to their typically developing siblings as matched controls (n = 30). Information regarding feeding practices was collected from mothers through a semi-structured questionnaire. Results: About 43.3% of children with ASD received exclusive breastfeeding, whereas 76.7% of their typically developing siblings were exclusively breastfed. Exclusive breastfeeding was associated with lower odds for ASD (odds ratio [OR] = 0.166; 95% confidence interval [CI] = 0.025-0.65), while early introduction of top feeds was associated with higher odds (OR = 6; 95% CI = 1.33-55.19). Difficulties in breastfeeding were attributed to child-related factors in 13.2% of the children. Conclusion: Children with ASD are suboptimally breastfed compared to their typically developing siblings. Exclusive breastfeeding may confer protection in vulnerable children. Further studies on larger prospective sample are required to establish the association. PMID- 29456358 TI - Surgically Treated Primary Spinal Cord Neoplasms in Southeastern Nigeria. AB - Background: Primary spinal cord tumors are not as frequently encountered as their cranial counterparts. They could present in such an indolent manner that requires a reasonable index of suspicion for their diagnosis to be considered. Objective: The objective of this study is to analyze the incidence and pattern of primary spinal cord and appendage neoplasms in patients surgically treated in our institution over a decade of practice. Materials and Methods: A retrospective review of clinical, radiological, and histopathology profiles of patients surgically treated for primary spinal cord tumor from 2006 to 2016 was carried out. Retrieved data were analyzed using SPSS version 21. Results: Out of 472 spine procedures were performed within the study period 17 (3.6%) cases of histologically proven primary spinal cord tumors were identified. The age of patients ranged between 17 and 77 years with a mean age was 45 years. The male: female ratio was 1:1.1. Motor deficit and pain were the most common presenting symptoms seen in 35.3% and 29.4% of patients, respectively. Meningiomas are the most common histological diagnosis (70.6%), distantly followed by Schwannoma (17.6%). The most common location of the tumors was intradural extramedullary (70.6%). All patients had gross total resection of tumor with no perioperative mortality. Conclusion: Meningioma is the most common surgically treated primary spinal cord tumor in our setting. Surgery is associated with good outcome. PMID- 29456359 TI - Comparison of Computerized and Standard Cognitive Test in Thai Memory Clinic. AB - Background: Computer-based Thai Cognitive Test or Computer-based Thai Mental State Examination (cTMSE) was developed aiming to help doctors to easily get the accurate results of TMSE in a routine, busy outpatient clinics. The purpose of this study was to compare the evaluation process in terms of feasibility, duration of the test, participants/administrator preference, and the results of cognitive test between cTMSE and the standard Thai Mental State Examination (sTMSE). Methods: Twenty-two elderly participants (>60 years old) who were not demented and 22 patients with mild-to-moderate dementia were included in the study. All participants would be asked to have TMSE by standard method (sTMSE) and computer-based method (cTMSE), at least 2 weeks and up to 2 months apart. Scores and duration of the test were compared using dependent paired t-test. Agreement of the tests between two methods and Kappa statistics were analyzed. Results: Paired t-test showed no significant difference in scores between the two methods (mean sTMSE vs. cTMSE: 22.84 vs. 22.62, 95% confidence interval [CI]: [ 0.465] to 0.987, P = 0.524). Percent of agreement between the two methods was 92.5%, with the Kappa of 0.85 (P < 0.001). Duration of the test by sTMSE was slightly shorter than the cTMSE (7.31 min vs. 7.97 min, 95% CI: [-1.159] to [ 0.175], P = 0.09). Overall, participants liked being tested by cTMSE more than sTMSE. Conclusion: Computer-based TMSE was feasible to use and accurate for screening in aging adults and for cognitive evaluation in patients with mild-to moderate dementia. PMID- 29456360 TI - Clinical Features and Psychiatric Comorbidity of Epicrania Fugax. AB - Background: Epicrania fugax (EF) is a rare newly described primary headache characterized by paroxysms of unilateral pain radiating across one hemicranium. Aim: We aimed to describe 10 new cases of EF and assess the psychiatric comorbidity. Materials and Methods: Cases of EF were identified from patients attending the neurology outpatient department of a tertiary level referral and teaching hospital by the first author during a period extending from January 1, 2015 to April 31, 2017. Case ascertainment was done as per ICHD 3 beta criteria from among patients presenting with complaints of headache after detailed history and clinical examination. Clinical and demographic features were noted and patients were subjected to Mini Neuropsychiatric Interview to screen for psychiatric comorbidity followed by Becks Anxiety/Depression Inventory. Results: A total of 10 subjects were obtained during the study period, 4 males, and 6 females. Mean age of subjects was 45.3 years (standard deviation-10). Seventy percent had anteroposterior, and 30% had posteroanterior radiation of pain. The most common character of pain was stabbing (50%) followed by electrical (40%) and pressing (10%). None of the subjects had autonomic symptoms or focal symptoms in the scalp while 30% subjects had hyperesthesia in the affected area of the scalp. Six subjects (60%) patients had episodic course while 40% had chronic course. Sixty percent had comorbid anxiety while one (10%) had comorbid depression. A significant relation was obtained between duration of disease and occurrence of anxiety as well as Becks Anxiety Inventory scores while there was no correlation with attack duration. There was also a nonsignificant correlation between visual analog score and occurrence of anxiety symptoms. Conclusions: Our study conclusively proves the existence of EF as a rare, distinct primary headache syndrome in our study population. It has a significant psychiatric comorbidity consisting of 60% of generalized anxiety disorder, 10% of panic attacks, and 10% of depression.

AB - Joubert syndrome (JS) is an autosomal recessive inherited disorder characterized by hypotonia, cerebellar vermis hypoplasia, ocular abnormalities (e.g., pigmentary retinopathy, oculomotor apraxia, and nystagmus), renal cysts, and hepatic fibrosis. Respiratory abnormalities, as apnea and hyperpnea, may be present, as well as mental retardation. Since the clinical findings of JS are quite heterogeneous, determination of radiological findings is essential. PMID- 29456361 TI - Upper Cervical Bronchogenic Cyst: A Rare Condition at a Rare Location. AB - Intraspinal bronchogenic cyst (SBC) is a rare but important cause of spinal cord compression, commonly seen in the cervicothoracic spine. We report a case of a 43 year-old male, presenting with complaints of neck pain, radiating to right shoulder, with numbness of right hand and fingers. Magnetic resonance imaging of the cervical spine revealed an intradural extramedullary, ventral cystic lesion extending from C2 to C4 vertebral levels. Complete surgical excision was performed, and the patient had a complete relief of symptoms postoperatively. Only 11 cases of SBCs have been reported in literature. We discuss the peculiar location of this lesion, possible embryological reasons and the overall surgical outcome of SBC. PMID- 29456363 TI - Inadvertent Central Arterial Catheterization: An Unusual Cause of Ischemic Stroke. AB - Central venous catheter (CVC) insertion is extensively utilized in Intensive Care Units for evaluation of hemodynamic status, administration of intravenous drugs, and for providing nutritional support in critically ill patients. Unfortunately, CVC use is associated with complications including lung injury, bleeding, infection, and thrombosis. We present a patient with an acute ischemic stroke from an inadvertently placed CVC into the right common carotid artery. A 57-year old male presented to our institution for left hemiplegia and seizures 2 days after a CVC was placed. He was found to have a right frontal ischemic stroke on computed tomography (CT). CT angiography noted that the catheter was arterial and had a thrombosis around it. He was started on a low-dose heparin infusion. A combination of cardiothoracic surgery and interventional cardiology was required to safely remove the catheter. Central arterial catheterization is an unusual cause for acute ischemic stroke and presents management challenges.

PMID- 29456375 TI - Assessment of Queries Received by the Drug Information Center at King Saud Medical City. AB - Background: The complexity of drug therapies has increased the need to evaluate the drug information scientifically. In this regard, the aim of drug information centers (DICs) is to promote rational use of drugs in a health-care setting. DI pharmacists play a vital role in providing the necessary and reliable information on drugs to promote the concept of rational drug use, eventually leading to a better patient outcome. The objective of the present study was to assess the drug related queries received by the DIC at the King Saud Medical City (KSMC) from health-care professionals working in a large tertiary care setting. Methods: A retrospective analysis was conducted from February 2016 to January 2017. Data were collected using the DI request form, available in both printed and electronic formats for use by the health-care professionals. Descriptive statistics were used to calculate frequencies and percentages. Data analysis was performed using the Statistical Package of the Social Sciences software, version 16.0. Results: The current study received a total of 139 queries that were answered by the DIC pharmacists over a period of 1 year. The majority of queries were asked by pharmacists (61.2%), followed by physicians (23.7%) and nurses (10.10%). About half of the queries were related to the dosage and administration of the drugs. Lexicomp(r) acted as the common resource of information. Conclusion: DIC has been instrumental in the dissemination of drug-related information to health-care professionals since its inception in February 2016, resulting in the provision of quality health care to the patients. However, based on yearly queries, there still exists a need to increase the awareness of health care professionals about the DIC at KSMC, which will urge them to take drug consultation from DIC pharmacists and promote patient safety.

AB - Introduction: Primaquine is vital for the management of liver-stage Plasmodium vivax and Plasmodium ovale malaria. However, primaquine effectiveness is dependent on various factors and differs between populations. Therefore, this study was conducted to identify factors that affect the length of stay and relapse during primaquine combination treatment in malaria-infected patients in the local setting. Materials and Methods: A retrospective study on the use of primaquine combination among P. vivax and P. ovale infected patients in Selangor, Malaysia within a 5-year period from 2011 to 2015 was obtained from the National Malaria Case Registry, Malaysia. Data collected were patient characteristics (age, gender, nationality, glucose-6-phosphate dehydrogenase, pregnancy); disease characteristics (survival, past malaria infection, parasite type, presence of gametocyte, parasite count, week onset, severity, transmission type); and treatment characteristics (type of antimalarial, treatment completion). Outcome measures were length of stay and relapse during a 1-year follow-up. Results: A total of 635 patients were included in the study. Based on a multivariate logistic regression analysis, the significant predictors for length of stay were gender (P = 0.009) and indigenous transmission (P < 0.001). Male patients had a shorter length of stay than females by 0.868 days (P = 0.009), and indigenous transmission took 1.82 days more compared to nonindigenous transmission (P < 0.001). Predictors for relapse were indigenous transmission of malaria (P = 0.019), which was 15.83 times more likely to relapse than nonindigenous transmission (P < 0.01). Conclusions: This study reveals that the effectiveness of primaquine was clinically associated with gender and indigenous transmission. To that end, vigilant monitoring of primaquine use is required to reduce relapse and future transmission.

AB - Objective: The objective was to report academic stress and prevalence of stress related self-medication among undergraduate female students of health and nonhealth cluster colleges at a public sector university in Dammam, Saudi Arabia. Materials and Methods: A 5-month cross-sectional survey was conducted in the university. The survey included the English version of 10-item Perceived Stress Scale (PSS) to report self-perceived stress. Student responses were analyzed by SPSS version 22 software. Results: The majority of students (85%) perceived examinations as a stressor. Most of the students (64%) had perceived moderate stress that increased as students progressed from preparatory year to 4th year. It declined in students of 5th and 6th year. The prevalence of stress related was reported at 39.58%. Highest prevalence of stress-induced self-medication was reported from College of Nursing (59.09%) and lowest (29.69%) from clinical pharmacy. Most common drug used to self-medicate during stress was caffeine (49.5%). The PSS score was significantly associated with colleges and study levels. Conclusion: Students studying in health cluster colleges reported high academic stress and self-medication practice. The major stressors identified were examination and course load. Student counseling sessions and counseling by pharmacists regarding self-care may help in the reduction of such stressors and may promote responsible self-medication. Self-evaluation and quality assurance process of curriculum may highlight areas for improvement in the courses. This may help in lowering academic stress among students. PMID- 29456378 TI - Utilization and Impact of Electronic and Print Media on the Patients' Health Status: Physicians' Perspectives. AB - Aims: Despite an increased popularity of print and electronic media applications, there is a paucity of data reflecting doctors' opinions regarding efficient utilization of these resources for the betterment of public health. Hence, this study aimed to investigate the perception of physicians toward the effect of electronic and print media on the health status of patients. Setting and Design: The current research is a cross-sectional study conducted from January 2015 to July 2015. The study population comprised physicians rendering their services in different hospitals of Karachi, Pakistan, selected by the nonprobability convenience sampling technique. In this study, 500 questionnaires were distributed through email or direct correspondence. Methods and Materials: Physicians' perception toward the impact of electronic and print media on the health status of patients was assessed with a 20-item questionnaire. Different demographic characteristics, such as age, gender, institution, position, and experience of respondents, were recorded. Quantitative data were analyzed with the use of Statistical Package for Social Sciences, version 20.0 (SPSS, Chicago, IL). The association of the demographic characteristics of the responses of physicians was determined by one-way ANOVA using 0.05 level of significance. Results: In this study, 254 physicians provided consent to show their responses for research purposes. A response rate of 50.8% was obtained. Nearly one-third of the respondents negated that patients get health benefit using electronic and print media. The majority did not consider electronic and print media as lifestyle-modifying factors. Physicians thought that patients particularly do not rely on mass media for acquiring health information and consider healthcare professionals as unswerving information resource. Conclusions: Mass media can be productive resources to augment awareness among patients, although physicians seem unconvinced about the extended usage of print/electronic media. PMID- 29456377 TI - Molecular Simulation Studies of 3,3'-Diindolylmethane as a Potent MicroRNA-21 Antagonist. AB - Objective: In recent decades, the overexpression of microRNA-21 (miR-21) is found to be progressively linked with many diseases such as different types of cancers, cardiovascular diseases, and inflammation. Thereby, it has become an attractive target for pharmacological and genetic modulation in various diseases, and also for overcoming the resistance to chemotherapy in several cancers. Here, in this study, the role of molecular therapeutics of 3,3'-diindolylmethane (DIM) has been investigated for its ability to bind with the precursor miRNA as a target of miR 21 (hsa-mir-21), which may alter the catalyzation process of dicer, a RNase III enzyme, involved in miRNA transcription. Methods: In this context, the present study describes the potential binding and the structure alteration properties of DIM to precursor miR-21 (pre-miR-21) through Molecular Docking and Molecular Dynamics simulation techniques. Results: As a corollary, DIM formed both non bonded and covalent interactions with the bases of pre-miR, while covalent interaction with guanine in the 6th position was found to be consensus in molecular dynamics simulation. Furthermore, the stability of both DIM and pre-miR 21 was found to be inversely correlated to each other in binding condition. Conclusion: This result indicates that DIM can be used in target-based therapy and also as a lead for further development of potent small molecule miRNA antagonist. PMID- 29456379 TI - Assessment of Health-related Quality of Life Among Asthmatic Patients: The Need for Structured Pharmaceutical Care Delivery System in Pakistan. AB - Asthma is considered as one of the most common chronic diseases in the world. As a result of serious physical, social, and psychological complications, asthma can reduce health-related quality of life (HRQoL). The present study was designed to assess the HRQoL including physical health, general health perception, emotional health, psychological health, and social functioning of asthmatic patients in Pakistan. A descriptive cross-sectional study design was used. Setting was public and private healthcare facilities. SF-36 was self-administered to a sample of 382 asthmatic patients. After data collection, data were clean coded and entered in SPSS version 21.0. Skewness test was performed and histograms with normal curves were used to check the normal distribution of data. Descriptive statistics comprising of frequency and percentages was calculated. The non-parametric tests including Mann-Whitney and Kruskal-Walis (P >= 0.05) were performed to find out the difference among different variables. The results of the current study highlighted a significant impact on several domains of HRQoL for asthmatic patients. Lowest scores for HRQoL were observed in the domain of general health (27.74 +/- 18.29) followed by domain of mental health (38.26 +/- 20.76) whereas highest scores were observed in the domain of social functioning (45.64 +/- 25.89). The results of the study concluded that asthmatic patients in Pakistan had poor HRQoL. Well-structured pharmaceutical care delivery in the healthcare facilities can contribute toward better patient knowledge and management and can ultimately improve the HRQoL of asthma patients. PMID- 29456380 TI - Moxibustion (Artemisia Plant at Acupuncture Point) as Alternative Therapy in Hypertension: A Promising Approach. AB - Hypertension is a pathological condition in which the blood pressure is higher than under normal physiological conditions, i.e., 140/90 mmHg or higher. Blood pressure is measured as the force exerted by the blood pumped by the heart against the walls of arteries (aorta) and distributed throughout the body. Use of complementary and alternative medicine as a cure for hypertension is a common phenomenon because of the high risk of cardiovascular complications and kidney diseases caused by conventional Western medicine. It is reported that high blood pressure causes ~49% of myocardial infarction and 62% of strokes. Effective treatment of hypertension is restricted by adverse effects and cost of the medication. Moxibustion is the application of heat by burning a small bundle of tightly bound moxa, to targeted acupoint, and sometimes it is used along with acupuncture. Encouraging results have been reported on randomized trials indicating the efficacy of moxibustion. But more controlled clinical trials are required to further establish the potential efficacy of moxibustion approach in hypertension.

PMID- 29456383 TI - Rediscovering the Drug Discovery with Natural Products as Therapeutic Tools. PMID- 29456384 TI - Tea Polyphenols and Prevention of Epigenetic Aberrations in Cancer. AB - Tea polyphenols are secondary metabolites of tea plants and are well known for beneficial health effects. They can protect from a variety of illnesses including cancers. Tea polyphenols can prevent cancer by modulating epigenetic aberrations taking place in DNA methylation, histone modifications, and micro-RNAs. By altering these epimutations, they regulate chromatin dynamics and expression of genes those induce or suppress cancer formation. However, majority of the studies in existing literature are carried out for green tea polyphenols rather than black tea polyphenols despite the fact that black tea is the most commonly consumed form of tea (78%) followed by green tea (20%) and other forms of tea. Research findings indicate that tea polyphenols may be potential source from which drugs with less side effects and affordable price can be developed. PMID- 29456385 TI - DNA Damage Protecting Activity and Antioxidant Potential of Launaea taraxacifolia Leaves Extract. AB - Background: The leaf extract of Launaea taraxacifolia commonly known as African Lettuce is used locally to treat dyslipidemia and liver diseases, which are associated with oxidative stress. Methanol extract from L. taraxacifolia leaves was tested for its antioxidant activity and its ability to protect DNA from oxidative damage. Materials and Methods: In vitro antioxidant potential of the leaf extract was evaluated using 1,1-diphenyl-2-picrylhydrazyl (DPPH), nitric oxide (NO), and hydroxyl (OH) radical scavenging assays. Ferric reducing power, total antioxidant capacity (TAC), metal chelating, and anti-lipid peroxidation ability of the extract were also examined using gallic acid, ascorbic acid, citric acid, and ethylenediaminetetraacetic acid as standards. Results: L. taraxacifolia leaves extract showed antioxidant activity with IC50 values of 16.18 MUg/ml (DPPH), 123.3 MUg/ml (NO), 128.2 MUg/ml (OH radical), 97.94 MUg/ml (metal chelating), 80.28 MUg/ml (TAC), and 23 MUg/ml (anti-lipid peroxidation activity). L. taraxacifolia leaves extract exhibited a strong capability for DNA damage protection at 20 mg/ml concentration. Conclusion: These findings suggest that the methanolic leaf extract of L. taraxacifolia could be used as a natural antioxidant and also as a preventive therapy against diseases such as arteriosclerosis associated with DNA damage. PMID- 29456387 TI - Clinico-epidemiological Profile of Pediatric Rheumatology Disorders in Eastern India. AB - Background: Data on rheumatological disorders in children from developing countries like India are scarce. Hence, this study aimed to understand the clinical and epidemiological profile of rheumatological disorders in children as this can help organize comprehensive evidence-based health care services. Methodology: A retrospective hospital-based study was designed in pediatric rheumatology clinic of the All India Institute of Medical Sciences, Patna, India, from January 2015 to December 2016. Clinical and laboratory findings and response to therapy of all children with rheumatological disorders were evaluated. Results: A total of 60 children with various rheumatological disorders were included in the study. Juvenile idiopathic arthritis (JIA) was the most common pediatric rheumatology disorder observed, and polyarticular JIA was the predominate subtype observed in our patients. The mean age of disease onset was 9.1 +/- 3.6 years (age range: 1-16 years). Methotrexate was the most common disease modifying antirheumatic drug used. None of the children received newer biological agents due to financial constraints. The use of alternative medicine was observed in 10% of cases. Conclusion: The clinical and epidemiological profile of children with rheumatological disorders in our patient group was different from the European countries and Western world. There is a need for introspecting the lack of using biological agents and its potential impact in managing JIA in our patient group. PMID- 29456386 TI - Perception of Patient Safety Culture among Health-care Providers in a Tertiary Care Hospital, South India. AB - Introduction: Patient safety is a global concern and is the most important domains of health-care quality. Medical error is a major patient safety concern, causing increase in health-care cost due to mortality, morbidity, or prolonged hospital stay. Aim: The aim of the study was to assess the perceptions on patient safety culture among health-care providers (HCPs) at a public sector tertiary care hospital in South India. Settings and Design: A hospital-based cross sectional study was conducted 1 year after patient safety initiatives were implemented. Materials and Methods: Participants were selected through proportionate stratified random sampling. The Hospital Survey on Patient Safety Culture was used to assess perception of patient safety culture. Responses were collected on a Likert scale and were categorized into four types as negative, neutral, positive response, and nonresponse. Statistical Analysis Used: The data were entered in EpiData Version 3.1 and analyzed using SPSS Version 17. "Composite positive response rate" for the various dimensions was calculated. Results: The overall response rate in the study was 91.6%. Average composite positive response rate was 58%, and it varied among different cadres of HCPs ranged from 53% to 61%. The dimensions "teamwork within the unit," "organizational learning and continuous improvement," and "supervisor or officer in-charge expectations" showed highest positive responses (80.1%, 77.8%, and 71.5%, respectively). Conclusions: This survey conducted after implementation of patient safety drive showed that, in many dimensions, the patient safety culture has taken roots. The dimensions such as "hand-off and transitions," "frequency of events reporting," and "communication openness" had scope for further improvement. PMID- 29456388 TI - Analgesic Properties of Nigella Sativa and Eucheuma Cottonii Extracts. AB - Background: This study investigates the analgesic properties of the aqueous extracts of Nigella sativa and Eucheuma cottonii in mice. The analgesic properties of both extracts were evaluated in an experimental model of acetic acid-induced writhing test. Materials and Methods: The mice were divided into four different groups and received the test extracts and the standard drug (aspirin) for 14 days via force-feeding. On day 15, the mice were injected with 5% acetic acid, and the number of abdominal constriction and elongation of hind limb (writhes) were counted for 20 min. Results: The numbers of writhes were counted starting after 5 min of the acetic acid injection. The N. sativa extracts significantly reduced the number of writhes as compared to the control group. Both of the extracts revealed a comparable result as referred to the aspirin effects in the mice. Conclusions: These findings indicate that N. sativa and E. cottonii may possess protective active constituent that is effective in reducing the sensation of pain in mice. PMID- 29456389 TI - Assessment of Quality of Prescription Writing among Dental and Medical Students and Practitioners in Kerala. AB - Background: The medical prescription is a valid and legal document.

Results and Conclusion: The total scores were found to be higher among dental fraternity (10.93 +/- 2.88) to medical (10.81 +/- 2.55). The medical house surgeons and postgraduates fared better in the doctor identification domain. Among the dental professionals, there was a significant difference among the undergraduates (mean score = 1.91) and postgraduates (mean score = 1.60) in the doctor identification domain. However, among the medical professionals, in the patient identification domain, house surgeons had a significantly higher score compared to postgraduates. There were no significant differences in quality of prescription writing among medical and dental professionals. PMID- 29456390 TI - Evaluation of Clinical and Magnetic Resonance Imaging Profile of Pituitary Macroadenoma: A Prospective Study. AB - Background: Pituitary macroadenoma is a common tumor of middle-aged people. Magnetic resonance imaging (MRI) is the investigation of choice for its evaluation. Various parameters regarding the extent, consistency, and contrast uptake can be studied and a noninvasive diagnosis is possible. Aims and Objectives: To study the MRI features and extent of pituitary macroadenomas. Materials and Methods: We studied clinical and MRI features of 33 patients of all age groups and both sexes with pituitary macroadenomas who presented to Dayanand Medical College and Hospital, Ludhiana from January 2014 to June 2015. MRI was carried out on MAGNETOM Avanto 18 Channel 1.5 Tesla Machine by Seimens India Ltd. The dedicated sellar protocol consisted of sagittal and coronal T1-weighted image (TI-WI) and T2-WI without intravenous contrast using thin slices (3 mm) and a field of view of <200 mm. Results: On analysis of the 33 cases, we observed that patients of pituitary macroadenoma showed an almost equal sex incidence and average age group of 50-60 years. The common presenting complaints were headache and decreased vision. Superior and inferior extent of the lesion was beyond the defined boundaries of sella in most cases, but the lateral extent was limited, resulting in characteristic "snowman-like" appearance. The imaging characteristics showed solid to predominantly solid consistency, appearing mostly heterogeneously hyperintense on T2-WI, and hypo to isointense on T1-WI with intense postcontrast enhancement. Hemorrhage is less common. Pituitary apoplexy is rare and can result in spontaneous resolution. Conclusions: We conclude that the knowledge of clinical and imaging profile of pituitary macroadenoma can help the radiologists to diagnose these sellar lesions, and hence their therapeutic approach can be defined timely. PMID- 29456392 TI - Chest X-Ray Findings Comparison between Multi-drug-resistant Tuberculosis and Drug-sensitive Tuberculosis. AB - Background: Imaging has a big role in tuberculosis (TB) diagnosis and chest X-ray is preferable because it is available in primary health care and can point out the location, area, and morphology of lesions, such as cavity, consolidation, pleural effusions, and fibrosis. We aimed to compare the chest X-ray findings in multi-drug resistant TB (MDR-TB) and in drug-sensitive TB (DS-TB) cases. Methods: This is a retrospective cross-sectional study which compares chest X-ray findings of two groups of patients, involving 183 DS-TB patients and 183 MDR-TB patients. Radiologic findings that we analyzed were infiltrate, consolidation, cavity, ground glass opacity, fibrosis, bronchiectasis, calcification, node, atelectasis, bullae, emphysema, and other nonlung parenchymal findings. Results: MDR-TB group have 177 (96%) patients with large lesions, 6 (4%) with medium lesions, and no small lesions. DS-TB group have 55 (30%) patients with small lesions, 78 (43%) with medium lesions, and 50 (27%) with large lesions. Active TB lesions in the forms of infiltrate and ground-glass opacity were more dominant in DS-TB group, whereas consolidation, cavity, fibrosis, bronchiectasis, calcification, node, atelectasis, bullae, emphysema, and other nonlung parenchymal findings, were more dominant in MDR-TB. Conclusions: There were significant differences in chest X ray findings between MDR-TB and DS-TB in terms of lesion size and morphology. Recognition of chest X-ray findings could help the physician to differentiate patient with suspected MDR-TB. PMID- 29456391 TI - The Use of Thromboelastography to Measure the Influence Inclusion of a Local Anesthetic Agent has on the Mechanical and Kinetic Properties of Fibrin. AB - Context: Delivery of slow-release local anesthesia has considerable potential for postoperative analgesia. Fibrin gel has shown huge potential for drug delivery, but has not been fully investigated for the delivery of local anesthetics nor has whether incorporation of anesthetic drugs into fibrin alters its mechanical properties. Aims: This study aimed to evaluate the effects of bupivacaine inclusion on the mechanical and kinetic properties of fibrin as measured by thromboelastography (TEG). Materials and Methods: Serial dilutions of fibrinogen with thrombin were tested with TEG to identify the optimal concentrations to give reproducible results. Following this, fibrinogen samples diluted with bupivacaine 0.5% in place of normal saline (also 1:20 dilution) were added to thrombin to assess what influence this had on clot strength and kinetics as measured by TEG values (with R, K, and alpha angle relating to clot kinetics and MA and G (or shear elastic modulus strength) relating to clot strength). Results: The mean values yielded for R were higher and lower for alpha angle, suggesting that the inclusion of bupivacaine produced a fibrin clot at a slower rate. The values for MA and G were both lower when bupivacaine was included, suggesting inclusion of the local anaesthetic also resulted in a fibrin clot of inferior strength. These results were not statistically significant. Conclusion: Although TEG failed to consistently measure these properties, the results suggest that inclusion of local anesthetic affects the clotting process of fibrin, potentially interfering with its ability to function as a sealant, adhesive, or hemostat. PMID- 29456393 TI - In vitro H+/K+-ATPase Inhibition, Antiradical Effects of a Flavonoid-rich Fraction of Dissotis rotundifolia, and In silico PASS Prediction of its Isolated Compounds. AB - Background: Dissotis rotundifolia, commonly referred to as pink lady, has several medicinal uses including peptic ulcer. This study investigated the inhibitory effects of D. rotundifolia extract on H+/K+-ATPase and also assessed its antiradical activity. In silico study of some isolated compounds of this plant was also carried out to affirm the suspected binding properties of extract to H+/K+-ATPase enzyme. Materials and Methods: D. rotundifolia whole plant extract was obtained after extraction process and then assessed for its ability to scavenge free radicals in four in vitro test models. Its ability to inhibit the activity of H+/K+-ATPase enzyme was also evaluated. Molecular docking was carried out on phytoconstituents, namely, vitexin, isovitexin, orientin, and isoorientin reported to be present in the whole plant extract. Results: Data obtained indicated that D. rotundifolia extract (DRE) exhibits strong antioxidant activity. DRE also showed inhibitory effects on H+/K+-ATPase enzyme activity. Docking studies affirmed the in vitro binding effect of the extract to H+/K+ ATPase. Conclusion: These findings suggest that the plant extract possess antioxidant and antipeptic ulcer activity. PMID- 29456394 TI - Assessment of Vitamin D in Rheumatoid Arthritis and Its Correlation with Disease Activity. AB - Background: Vitamin D is believed to have an immunomodulatory and anti inflammatory action, and its deficiency has been linked with several autoimmune disorders, including rheumatoid arthritis (RA). The relationship between the severity of RA and serum levels of Vitamin D is a subject of immense interest and therapeutic implications. Materials and Methods: This was a prospective, comparative study conducted on 100 participants, 50 cases of RA and 50 healthy controls, all in the age group of 18-75 years. Serum Vitamin D levels were measured and compared in cases and controls. Vitamin D levels in RA patients were also assessed in different stages of disease activity to assess the correlation between the two. Results: Eighty-four percent patients of RA were Vitamin D deficient versus only 34% of controls. The serum Vitamin D levels were also significantly lower in the RA patients (mean value of 21.05 +/- 10.02 ng/ml), as compared to the controls (mean value of 32.87 +/- 14.16 ng/ml). There was a significant inverse correlation between serum Vitamin D levels and RA disease activity. The mean serum Vitamin D levels were 35.28 +/- 9.0 ng/ml, 33.80 +/- 4.1 ng/ml, 22.47 +/- 6.18 ng/ml, and 14.21 +/- 6.97 ng/ml in the remission, low disease activity, moderate disease activity, and high disease activity groups, respectively. Conclusions: Vitamin D deficiency is more common in RA patients and may be one of the causes leading to development or worsening of the disease.

AB - Objectives: The objective of the study is to study the incidence and pattern of mandible fractures in the holy city of Madinah in the Kingdom of Saudi Arabia over a retrospective period of 3 years from 2013 (1434H) to 2016 (1436H) and to compare the results with those from other regions of Saudi Arabia and elsewhere. Materials and Methods: Relevant data of patients admitted to the King Fahad Hospital, Madinah with a fracture of the mandible during the study were collected from their medical records and radiographs. The age, gender, etiology, role of the patient, site, and number of fractures in the patients were evaluated. The data were analyzed by standard statistical methods. Results: A total of 197 patients with fracture of the mandible were admitted in the period of the study by the Oral Maxillofacial Surgery Department, King Fahad Hospital, Madinah. There were 165 male and 32 female patients. The ages ranged from 3 to 86 years with a mean of 24 years. A total of 260 fractures of Mandible were documented. The largest number (113) of patients was found in the age group between 16 and 30 years. Trauma caused by motor vehicle road traffic accidents (RTAs) was the main etiology of the fractures followed by falls and assault. The majority of the patients were in the role of vehicle drivers. The condylar anatomical site of mandible was most frequently affected and constituted the largest number (103) of fractures followed by the angle (51), parasymphysis (45), and then by the body (23) of the mandible. Dentoalveolar fractures were present in 22 cases. Very less number of coronoid fractures (7), followed by those of the ramus (5), and least number at the symphysis (4) of the mandible were found. Conclusion: RTA was the most common etiology for trauma and fracture of the mandible. The males outnumbered the female patients, the largest number of patients with trauma and mandible fracture was found in the age group between 16 and 30 years and frequency of condylar fractures was higher. PMID- 29456396 TI - Gingival Tissue Response Following Placement of a Light Cure Dressing and a Non eugenol Dressing after Periodontal Flap Procedure: A Comparative Clinical Study. AB - Aim: The aim was to compare the gingival tissue response following placement of a light cure dressing (Barricaid(r)) and a non-eugenol periodontal dressing (Coe PakTM) after periodontal flap procedure. This was carried out by evaluating plaque deposition underneath both the dressings, healing response and the patient preference for each. Materials and Methods: A total of 12 patients with chronic generalized periodontitis requiring surgery in at least two different quadrants were enrolled for this split-mouth study. After periodontal flap surgery, Coe PakTM was placed in the quadrant assigned to Group I and Barricaid(r) was placed in the other quadrant assigned to Group II. Clinical parameters were recorded on day 7 and day 14. Patient comfort and pain levels were also evaluated by a questionnaire. Results: There were no statistically significant differences in wound healing and the clinical gingival parameters between two groups. The only significant difference was found in the plaque attached underneath the dressing, with Coe-PakTM showing greater plaque accumulation than Barricaid(r). Seventy five (75) % of the patients preferred Barricaid(r) over Coe-PakTM, based on its appearance and taste. Conclusion: The non-eugenol dressing seemed to retain more plaque on its undersurface than light-cure dressing. However, this did not have much influence on the healing outcome and clinical gingival parameters, which were optimal and comparable in both groups. The greater number of patients showed a preference for light cure dressing, based on its superior esthetics and taste. PMID- 29456397 TI - Periodontal Flap Surgery along with Vestibular Deepening with Diode Laser to Increase Attached Gingiva in Lower Anterior Teeth: A Prospective Clinical Study. AB - Background: Chronic periodontitis in lower anterior teeth results in rapidly progressive gingival recession (GR), loss of alveolar bone, decreased vestibular depth (VD) with consequential tooth mobility, and tooth loss. Treatment option for such cases in this esthetically important area of the oral cavity includes extraction followed by implants for which sufficient bone height and mucogingival complex are a prerequisite. Henceforth, an attempt was made to prolong the life of lower anterior teeth and postpone the need for implants by the treatment of chronic periodontitis with periodontal flap surgery followed by vestibular deepening in single surgical procedure. Materials and Methods: In this clinical, prospective study, conventional periodontal flap surgery was done on 74 sites in lower anterior teeth in 16 patients with attachment loss >5 mm due to chronic periodontitis. Vestibular deepening with diode laser at (wavelength - 810 nm, output power: 0.5-7 W, continuous wave, contact mode) was done after suturing the flap. All the clinical parameters: GR, pocket depth (PD), clinical attachment loss (CAL), width of keratinized gingiva, width of attached gingiva, and VD were assessed preoperatively after Phase I therapy and 6 months postoperatively. Results: At all the 74 sites, there was highly significant gain in attached gingiva, keratinized gingiva, and VD (P <= 0.001). Highly significant reduction in PD (P <= 00.001), significant reduction in attachment loss (P <= 0.01) but no significant reduction in GR (P = 0.897) was observed. Conclusions: The combination of periodontal flap surgery with vestibular deepening with diode laser may be a suitable cost-effective treatment option to prolong the life of periodontally involved lower anterior teeth. The surgical technique can postpone the need for extraction of teeth along with all the intangible benefits of periodontal therapy. PMID- 29456398 TI - Urinary Cotinine Level in Indonesian Children Exposed to Domestic Cigarette Smoke. AB - Background: Cotinine is a major metabolite of nicotine, and its urinary level is an indicator of exposure to cigarette smoke. The present study was aimed at identifying the urinary cotinine level in Indonesian children who were exposed and not exposed to domestic cigarette smoke. Methods: The study was a cross sectional study in elementary school-aged children who had not smoked. The subjects were categorized into an exposed group and unexposed group based on their exposure status. Data were obtained from a questionnaire and random urinary samples measured using enzyme-linked immunosorbent assay. Results: There were a total of 128 subjects, including 64 children in the exposed group and 64 children in the unexposed group. The median level of cotinine in all subjects was 17.95 ng/ml (with a range of 0.1-158.3 ng/ml). The urinary cotinine level in the exposed group was higher than the unexposed group (median: 30.1 ng/ml vs. 8.45 ng/ml; P < 0.000). There was a correlation between urinary cotinine levels in children exposed to cigarette smoke and the number of cigarettes smoked by the smokers at home (P < 0.05). The optimal cut-off points of urinary cotinine levels in children, which was utilized to evaluate cigarette smoke exposure, was 17.95 ng/ml (81% sensitivity; 81% specificity; P < 0.000). Conclusion: The urinary cotinine level in children exposed to cigarette smoke is higher than children who are not exposed to domestic cigarette smoke. The urinary cotinine level can be used as a noninvasive marker to evaluate cigarette smoke exposure in children. PMID- 29456399 TI - Preprocedural Anxiety and Pain Perception Following Root Surface Debridement in Chronic Periodontitis Patients. AB - Background: The aim of this study was to evaluate and compare preprocedural dental anxiety levels and postprocedural pain perception in chronic periodontitis patients during conventional-staged root surface debridement (RSD) and single stage RSD. Materials and Methods: Thirty-seven adult generalized chronic periodontitis patients requiring RSD were recruited in this study. Preprocedural anxiety levels were assessed using a self-reported questionnaire and postprocedural pain perceptions were assessed using 0-10 cm visual analog scale. The subject population was divided into two groups: staged RSD (n = 18) and single-stage RSD (n = 19). Staged RSD patients visited four times as opposed to single-stage RSD patients. Data were subjected to Pearson Chi-square test, Mann Whitney U-test, and Spearman's rank correlation. Results: There was no statistically significant difference in dental anxiety levels or pain perceptions in both the groups. Within Group 1, there was statistical significant difference in dental anxiety levels between visit 4 and visit 3 (P = 0.037) and pain perception between visit 3 and visit 1 (P = 0.005), visit 4 and visit 1 (P = 0.002), and visit 4 and visit 2 (0.04) was statistically significant. There was a positive correlation of anxiety questionnaire (Q1-Q4) to the pain score in Group 1 which was statistically significant and in single-stage RSD. Conclusion: Conventional quadrant-wise RSD tends to cognitively condition the anxiety experience thus influencing pain experience. PMID- 29456400 TI - Unilateral Transient Watershed Cerebral Infarct in a 6-Year-Old Girl with Frequently Relapsing Nephrotic Syndrome. AB - Nephrotic syndrome is a prothrombotic state with predisposition to venous sinus thrombosis and arterial vascular stroke. Watershed infarcts in junction of arterial territory develop in hypotensive hypovolemic state. These border zone infarcts are usually bilateral in the absence of unilateral arterial stenosis or microembolism. We report a 6-year-girl of frequently relapsing nephrotic syndrome who developed sudden onset hemiparesis with aphasia. Magnetic resonance (MR) imaging brain revealed unilateral watershed infarct in territory between the major cerebral arterial vessels with evidence of restricted diffusion and normal vessel anatomy on MR angiography. This could possibly reflect asymmetric variant of posterior reversible encephalopathy syndrome that resolved with remission on steroids. PMID- 29456401 TI - Management of Complicated Crown Fracture by Reattachment Using Fiber Post: Minimal Intervention Approach. AB - Anterior crown fractures are a common form of traumatic dental injuries that mainly affect the maxillary incisors, especially in children and adolescents. Complicated crown fractures although less common, pose a challenge to the clinician. The main objective while treating such cases is successful pain management and immediate restoration of function, esthetics and phonetics. Since the development of the adhesive dentistry, the patient's own fragment can be used to restore the fractured tooth. Reattachment of fractured tooth fragments offers a viable restorative alternative. The procedure provides good and long-lasting esthetics, because the original morphology, color, and surface texture are preserved. This article reports management of complicated crown fracture in a young adult and a middle-aged adult that were successfully treated by reattachment technique. The teeth were endodontically treated followed by esthetic reattachment of the fractured fragment using the glass fiber post. To improve the adhesion between fractured and remaining fragment, circumferential beveling and internal groove placement were done. PMID- 29456402 TI - Hemisection as a Conservative Management of Grossly Carious Permanent Mandibular First Molar. AB - Hemisection of a molar denotes removal or separation of a root along with its accompanying part of crown. It is a suitable treatment option when the caries, resorption, perforation, or periodontal damage is restricted to one root while the other root is relatively healthy. Hemisection of the affected tooth helps to retain the tooth structure, surrounding alveolar bone, and may also facilitate the placement of fixed prosthesis. This case report describes the hemisection as a successful treatment method to save a grossly carious mandibular first molar with periodontal and periapical involvement. Hemisection and prosthetic rehabilitation yielded a satisfactory result. With careful treatment planning and precise surgical management, undesirable consequences of tooth loss were prevented. PMID- 29456403 TI - Severe Abdominal Complaints after Technical Successful Endovascular Treatment of Chronic Splanchnic Ischemia. AB - Reperfusion syndrome (RS) after revascularization of an arterial occlusion of the lower leg is a well-known complication. RS after splanchnic revascularization, however, is an infrequent and less-known phenomenon. We present a patient with persisting abdominal complaints after revascularization of the celiac trunk and superior mesenteric artery suggesting reocclusion. Although computed tomography angiography showed patent splanchnic arteries, an impressive hyperperfusion state of liver and spleen was visualized. Complaints diminished steadily with conservative therapy, but RS can cause severe complications such as liver failure and multiple organ failure. Ignorance of RS might interfere with adequate treatment and can contribute to a high in-hospital mortality rate. PMID- 29456404 TI - "Thanatophobia": Physician's Perspective of Dealing with Patients with Fear of Death. PMID- 29456405 TI - Role of PTPN2/22 polymorphisms in pathophysiology of Crohn's disease. AB - AIM: To establish the relationship of protein tyrosine phosphatase non-receptor type 2 and 22 (PTPN2/22) polymorphisms and mycobacterial infections in Crohn's disease (CD). METHODS: All 133 subjects' blood samples were genotyped for nine single nucleotide polymorphisms (SNPs) in PTPN2/22 using TaqManTM genotyping, while the effect of the SNPs on PTPN2/22 and IFN-gamma gene expression was determined using RT-PCR. Detection of Mycobacterium avium subspecies paratuberculosis (MAP) IS900 gene was done by nPCR after DNA extraction from the isolated leukocytes of each subjects' blood samples. T-cells isolated from the patient samples were tested for response to phytohematoagglutonin (PHA) mitogen or mycobacterial antigens by BrdU proliferation assays for T-cell activity. RESULTS: Out of the nine SNPs examined, subjects with either heterozygous (TC)/minor (CC) alleles in PTPN2:rs478582 occurred in 83% of CD subjects compared to 61% healthy controls (P-values < 0.05; OR = 3.03). Subjects with either heterozygous (GA)/minor (AA) alleles in PTPN22:rs2476601 occurred in 16% of CD compared to 6% healthy controls (OR = 2.7). Gene expression in PTPN2/22 in CD subjects was significantly decreased by 2 folds compared to healthy controls (P values < 0.05). IFN-gamma expression levels were found to be significantly increased by approxiately 2 folds in subjects when either heterozygous or minor alleles in PTPN2:rs478582 and/or PTPN22:rs2476601 were found (P-values < 0.05). MAP DNA was detected in 61% of CD compared to only 8% of healthy controls (P values < 0.05, OR = 17.52), where subjects with either heterozygous or minor alleles in PTPN2:rs478582 and/or PTPN22:rs2476601 had more MAPbacteremia presence than subjects without SNPs did. The average T-cell proliferation in CD treated with PHA or mycobacteria antigens was, respectively, 1.3 folds and 1.5 folds higher than healthy controls without any significant SNP. CONCLUSION: The data suggests that SNPs in PTPN2/22 affect the negative regulation of the immune response in CD patients, thus leading to an increase in inflammation/apoptosis and susceptibility of mycobacteria. PMID- 29456406 TI - Health-related quality of life, anxiety, depression and impulsivity in patients with advanced gastroenteropancreatic neuroendocrine tumours. AB - AIM: To compare health-related quality of life (HRQoL), anxiety, depression, and impulsivity scores in patients with and without carcinoid syndrome (CS), and correlated them with serum 5-hydroxyindoleacetic acid (5-HIAA) levels. METHODS: Patients with advanced gastroenteropancreatic neuroendocrine tumours (GEPNET), with and without CS completed HRQoL QLQ-C30 and QLQ-GI.NET21, Hospital Anxiety and Depression Scale (HADS) and Barratt Impulsivity Scale (BIS) questionnaires. Two-sample Wilcoxon test was applied to assess differences in serum 5-HIAA levels, two-sample Mann-Whitney U test for HRQoL and BIS, and proportion test for HADS, between those with and without CS. RESULTS: Fifty patients were included; 25 each with and without CS. Median 5-HIAA in patients with and without CS was 367nmol/L and 86nmol/L, respectively (P = 0.003). Scores related to endocrine symptoms were significantly higher amongst patients with CS (P = 0.04) and scores for disease-related worries approached significance in the group without CS, but no other statistically-significant differences were reported between patients with and without CS in responses on QLQ-C30 or QLQ-GI.NET21. Fifteen patients (26%) scored >= 8/21 on anxiety scale, and 6 (12%) scored >= 8/21 on depression scale. There was no difference in median 5-HIAA between those scoring < or >= 8/21 on anxiety scale (P = 0.53). There were no statistically significant differences between groups in first or second-order factors (BIS) or total sum (P = 0.23). CONCLUSION: Excepting endocrine symptoms, there were no significant differences in HRQoL, anxiety, depression or impulsivity between patients with advanced GEPNET, with or without CS. Over one quarter of patients had high anxiety scores, unrelated to peripheral serotonin metabolism. PMID- 29456407 TI - Analysis of hepatitis B virus preS1 variability and prevalence of the rs2296651 polymorphism in a Spanish population. AB - AIM: To determine the variability/conservation of the domain of hepatitis B virus (HBV) preS1 region that interacts with sodium-taurocholate cotransporting polypeptide (hereafter, NTCP-interacting domain) and the prevalence of the rs2296651 polymorphism (S267F, NTCP variant) in a Spanish population. METHODS: Serum samples from 246 individuals were included and divided into 3 groups: patients with chronic HBV infection (CHB) (n = 41, 73% Caucasians), patients with resolved HBV infection (n = 100, 100% Caucasians) and an HBV-uninfected control group (n = 105, 100% Caucasians). Variability/conservation of the amino acid (aa) sequences of the NTCP-interacting domain, (aa 2-48 in viral genotype D) and a highly conserved preS1 domain associated with virion morphogenesis (aa 92-103 in viral genotype D) were analyzed by next-generation sequencing and compared in 18 CHB patients with viremia > 4 log IU/mL. The rs2296651 polymorphism was determined in all individuals in all 3 groups using an in-house real-time PCR melting curve analysis. RESULTS: The HBV preS1 NTCP-interacting domain showed a high degree of conservation among the examined viral genomes especially between aa 9 and 21 (in the genotype D consensus sequence). As compared with the virion morphogenesis domain, the NTCP-interacting domain had a smaller proportion of HBV genotype-unrelated changes comprising > 1% of the quasispecies (25.5% vs 31.8%), but a larger proportion of genotype-associated viral polymorphisms (34% vs 27.3%), according to consensus sequences from GenBank patterns of HBV genotypes A to H. Variation/conservation in both domains depended on viral genotype, with genotype C being the most highly conserved and genotype E the most variable (limited finding, only 2 genotype E included). Of note, proline residues were highly conserved in both domains, and serine residues showed changes only to threonine or tyrosine in the virion morphogenesis domain. The rs2296651 polymorphism was not detected in any participant. CONCLUSION: In our CHB population, the NTCP-interacting domain was highly conserved, particularly the proline residues and essential amino acids related with the NTCP interaction, and the prevalence of rs2296651 was low/null. PMID- 29456408 TI - Inhibitory effects of patchouli alcohol on stress-induced diarrhea-predominant irritable bowel syndrome. AB - AIM: To elucidate the mechanism of patchouli alcohol (PA) in treatment of rat models of diarrhea-predominant irritable bowel syndrome (IBS-D). METHODS: We studied the effects of PA on colonic spontaneous motility using its cumulative log concentration (3 * 10-7 mol/L to 1 * 10-4 mol/L). We then determined the responses of the proximal and distal colon segments of rats to the following stimuli: (1) carbachol (1 * 10-9 mol/L to 1 * 10-5 mol/L); (2) neurotransmitter antagonists including Nomega-nitro-L-arginine methyl ester hydrochloride (10 MUmol/L) and (1R*, 2S*)-4-[2-Iodo-6-(methylamino)-9H-purin-9-yl]-2 (phosphonooxy)bicyclo[3.1.0]hexane-1-methanol dihydrogen phosphate ester tetraammonium salt (1 MUmol/L); (3) agonist alpha,beta-methyleneadenosine 5' triphosphate trisodium salt (100 MUmol/L); and (4) single KCl doses (120 mmol/L). The effects of blockers against antagonist responses were also assessed by pretreatment with PA (100 MUmol/L) for 1 min. Electrical-field stimulation (40 V, 2-30 Hz, 0.5 ms pulse duration, and 10 s) was performed to observe nonadrenergic, noncholinergic neurotransmitter release in IBS-D rat colon. The ATP level of Kreb's solution was also determined. RESULTS: PA exerted a concentration dependent inhibitory effect on the spontaneous contraction of the colonic longitudinal smooth muscle, and the half maximal effective concentration (EC50) was 41.9 MUmol/L. In comparison with the KCl-treated IBS-D group, the contractile response (mg contractions) in the PA + KCl-treated IBS-D group (11.87 +/- 3.34) was significantly decreased in the peak tension (P < 0.01). Compared with CCh treated IBS-D rat colon, the cholinergic contractile response of IBS-D rat colonic smooth muscle (EC50 = 0.94 MUmol/L) was significantly decreased by PA (EC50 = 37.43 MUmol/L) (P < 0.05). Lack of nitrergic neurotransmitter release in stress-induced IBS-D rats showed contraction effects on colonic smooth muscle. Pretreatment with PA resulted in inhibitory effect on L-NAME-induced (10 MUmol/L) contraction (P < 0.05). ATP might not be the main neurotransmitter involved in inhibitory effects of PA in the colonic relaxation of stress-induced IBS-D rats. CONCLUSION: PA application may serve as a new therapeutic approach for IBS-D. PMID- 29456409 TI - Recombinant expressed vasoactive intestinal peptide analogue ameliorates TNBS induced colitis in rats. AB - AIM: To investigate the modulatory effect of recombinant-expressed vasoactive intestinal peptide (VIP) analogue (rVIPa) on trinitrobenzene sulfonic acid (TNBS) induced colitis in rats. METHODS: Forty-eight rats were randomized into six groups: normal control group (Control), model control group (TNBS), ethanol treatment group (ETOH), and VIP treatment groups with different dosage (rVIPa1nmol, rVIPa2nmol, rVIPa4nmol). Diarrhea and bloody stool were observed. Colonic damage was evaluated histologically. The levels of tumor necrosis factor alpha (TNF-alpha), interleukin-10 (IL-10), myeloperoxidase (MPO) and endotoxin in colonic tissue and serum were determined by enzyme-linked immunosorbent assay (ELISA). The expression of occludin, ZO-1, Toll-like receptor 4 (TLR4), and nuclear factor-kappa B p65 (NF-kappaB p65), IkappaBalpha, and p-IkappaBalpha were detected by Western blot. RESULTS: Administration with 2 nmol rVIPa prevented TNBS-induced necrosis, hyperemia, swelling, inflammation, etc., pathologic changes observed in the inner surface of colon in experimental rats. Moreover, rVIPa significantly decreased colonic TNF-alpha level (P < 0.001), MPO activity (P < 0.001) and serum endotoxin level (P < 0.01), and remarkably increased colonic IL-10 content (P < 0.001) in rats with TNBS-induced colitis. Furthermore, compared to the TNBS-induced colitis group, 2 nmol rVIPa treatment up-regulated the levels of occludin (P < 0.05) and ZO-1 (P < 0.05), NF-kappaB p65 (P < 0.01) and IkappaBalpha (P < 0.001), and down-regulated the levels of TLR4. CONCLUSION: rVIPa ameliorates TNBS-induced colonic injury and inflammation and effectively protected the intestinal mucosal barrier function in rats. The mechanism may be related to TLR4/NF-kappaB-mediated signaling pathway. rVIPa could be used as a new alternative therapy for intestinal inflammatory disorders. PMID- 29456410 TI - Split-dose bowel preparation improves adequacy of bowel preparation and gastroenterologists' adherence to National Colorectal Cancer Screening and Surveillance Guidelines. AB - AIM: To quantify the impact of split-dose regimen on endoscopists' compliance with guideline recommendations for timing of repeat colonoscopy in patients with normal colonoscopy or 1-2 small polyps (< 10 mm). METHODS: A retrospective chart review of all endoscopy reports was undertaken in average-risk individuals > 50 years old with a normal screening colonoscopy and 1-2 small polyps. Data were abstracted from two time periods, pre and post-split-dose bowel preparation institution. Main outcome measurements were recommendation for timing of repeat colonoscopy and bowel preparation quality. Bivariate analysis by chi2 tests and Student's t-tests were performed to assess differences between the two cohorts. Multivariable logistic regression was used with guideline consistent recommendations as the dependent variables and an indicator for 2011 cohort as the primary predictor. RESULTS: Four thousand two hundred and twenty-five patients were included in the study; 47.0% (1987) prior to the institution of split dose bowel preparation, and 53.0% (2238) after the institution of split dose bowel preparation. Overall, 82.2% (n = 3472) of the colonoscopies were compliant with guideline recommendations, with a small but significantly increased compliance rate in year 2011 (83.7%) compared to year 2009 (80.4%, P = 0.005), corresponding to an unadjusted odds ratio of 1.25 (95%CI: 1.07-1.47; P = 0.005). Colonoscopies with either "Adequate" or "Excellent" had increased from 30.6% in year 2009 to 39.6% in year 2011 (P < 0.001). However, there was no significant difference in poor/inadequate category of bowel preparation as there was a mild increase from 4.6% in year 2009 to 5.1% in year 2011 (P = 0.50). CONCLUSION: Split-dose bowel regimen increases endoscopists' compliance to guidelines in average-risk patients with normal colonoscopy or 1-2 small polyps. PMID- 29456411 TI - Clinical utility of hepatitis B surface antigen kinetics in treatment-naive chronic hepatitis B patients during long-term entecavir therapy. AB - AIM: To investigate the utility of hepatitis B surface antigen (HBsAg) kinetics in chronic hepatitis B patients during long-term entecavir treatment. METHODS: This retrospective study included treatment-naive chronic hepatitis B patients who received at least 2 years of consecutive entecavir treatment. Patients were followed up at three to six month intervals with liver biochemistry, hepatitis B virus DNA, and abdominal sonography. In hepatitis B e antigen (HBeAg)-positive patients, HBeAg levels were assessed every three to six month until results became negative. Serum HBsAg levels were determined at the baseline, one-year and five-year time points. Liver cirrhosis was diagnosed through liver biopsy, imaging examinations, or clinical findings of portal hypertension. Hepatocellular carcinoma was diagnosed by histological examination or dynamic image studies. RESULTS: A total of 211 patients were enrolled. The median treatment time was 5.24 (2.00-9.62) years. Multivariate analysis showed that lower baseline HBsAg levels were associated with an earlier virological response, earlier hepatitis B e antigen (HBeAg) seroconversion, and earlier biochemical response in HBeAg positive patients (cut-off value: 4 log IU/mL) and an earlier virological response in HBeAg-negative non-cirrhotic patients (cut-off value: 2.4 log IU/mL). Although HBsAg levels decreased slowly during long-term entecavir treatment, higher HBsAg decrease rates were found in the first year for HBeAg-positive non cirrhotic patients, and patients with higher baseline HBsAg levels. More favorable clinical outcomes were not observed by a rapid HBsAg decline per se, but depended on lower baseline HBsAg levels. CONCLUSION: Baseline HBsAg can be used to predict treatment responses. HBsAg levels and decrease rates should be considered together according to disease status while interpreting HBsAg changes. PMID- 29456412 TI - Performance of transient elastography in assessing liver fibrosis in patients with autoimmune hepatitis-primary biliary cholangitis overlap syndrome. AB - AIM: To investigate the performance of transient elastography (TE) for diagnosis of fibrosis in patients with autoimmune hepatitis-primary biliary cholangitis (AIH-PBC) overlap syndrome. METHODS: A total of 70 patients with biopsy-proven AIH-PBC overlap syndrome were included. Spearman correlation test was used to analyze the correlation of liver stiffness measurement (LSM) and fibrosis stage. Independent samples Student's t-test or one-way analysis of variance was used to compare quantitative variables. Receiver operating characteristics (ROC) curve was used to calculate the optimal cut-off values of LSM for predicting individual fibrosis stages. A comparison on the diagnostic accuracy for severe fibrosis was made between LSM and other serological scores. RESULTS: Patients with AIH-PBC overlap syndrome had higher median LSM than healthy controls (11.3 +/- 6.4 kPa vs 4.3 +/- 1.4 kPa, P < 0.01). LSM was significantly correlated with fibrosis stage (r = 0.756, P < 0.01). LSM values increased gradually with an increased fibrosis stage. The areas under the ROC curves of LSM for stages F >= 2, F >= 3, and F4 were 0.837 (95%CI: 0.729-0.914), 0.910 (0.817-0.965), and 0.966 (0.893-0.995), respectively. The optimal cut-off values of LSM for fibrosis stages F >= 2, F >= 3, and F4 were 6.55, 10.50, and 14.45 kPa, respectively. LSM was significantly superior to fibrosis-4, glutaglumyl-transferase/platelet ratio, and aspartate aminotransferase-to-platelet ratio index scores in detecting severe fibrosis (F >= 3) (0.910 vs 0.715, P < 0.01; 0.910 vs 0.649, P < 0.01; 0.910 vs 0.616, P < 0.01, respectively). CONCLUSION: TE can accurately detect hepatic fibrosis as a non-invasive method in patients with AIH-PBC overlap syndrome. PMID- 29456413 TI - Value of contrast-enhanced ultrasound in the differential diagnosis of gallbladder lesion. AB - AIM: To describe contrast-enhanced ultrasound (CEUS) features and evaluate differential diagnosis value of CEUS and conventional ultrasound for patients with benign and malignant gallbladder lesions. METHODS: This study included 105 gallbladder lesions. Before surgical resection and pathological examination, conventional ultrasound and CEUS were performed to examine for lesions. Then, all the lesions were diagnosed as (1) benign, (2) probably benign, (3) probably malignant or (4) malignant using both conventional ultrasound and CEUS. The CEUS features of these gallbladder lesions were analyzed and diagnostic efficiency between conventional ultrasound and CEUS was compared. RESULTS: There were total 17 cases of gallbladder cancer and 88 cases of benign lesion. Some gallbladder lesions had typical characteristics on CEUS (e.g., gallbladder adenomyomatosis had typical characteristics of small nonenhanced areas on CEUS). The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of CEUS were 94.1%, 95.5%, 80.0%, 98.8% and 95.2%, respectively. These were significantly higher than conventional ultrasound (82.4%, 89.8%, 60.9%, 96.3% and 88.6%, respectively). CEUS had an accuracy of 100% for gallbladder sludge and CEUS helped in differential diagnosis among gallbladder polyps, gallbladder adenoma and gallbladder cancer. CONCLUSION: CEUS may provide more useful information and improve the diagnosis efficiency for the diagnosis of gallbladder lesions than conventional ultrasound. PMID- 29456414 TI - High prevalence of hepatitis B-antibody loss and a case report of de novo hepatitis B virus infection in a child after living-donor liver transplantation. AB - AIM: To assess the seroprevalence of hepatitis B virus (HBV) immunity among previously vaccinated pediatric liver transplant recipients and present a case report of de novo hepatitis B infection after liver transplantation. METHODS: This study focused on children with chronic liver diseases who received primary hepatitis B immunization and had a complete dataset of anti-HBs before and after liver transplantation between May 2001 and June 2017. Medical records were retrospectively reviewed for potential factors relating to HBV immunity loss. RESULTS: In total, 50 children were recruited. The mean time from liver transplantation to anti-HBs testing was 2.53 +/- 2.11 years. The mean anti-HBs levels before and after liver transplantation were 584.41 +/- 415.45 and 58.56 +/ 6.40 IU/L, respectively. The rate of non-immunity (anti-HBs < 10 IU/L) in the participants was 46% (n = 26) at one year, 57% (n = 7) at two years and 82% (n = 17) at > three years following liver transplantation. The potential factors relating to HBV immunity loss after liver transplantation were identified as anti HBs (P = 0.002), serum albumin (P = 0.04), total bilirubin (P = 0.001) and direct bilirubin (P = 0.003) before liver transplantation. A five-year-old boy with biliary cirrhosis received 4 doses of HBV vaccine with an anti-HBs titer of > 1000 IU/L and underwent liver transplantation; his anti-HBc-negative father was the donor. After liver transplantation, the boy had stenosis of the hepatic artery up to the inferior vena cava anastomosis and underwent venoplasty three times. He also received subcutaneous injections of enoxaparin for 5 mo and 20 transfusions of blood components. Three years and ten months after the liver transplantation, transaminitis was detected with positive tests for HBsAg, HBeAg, and anti-HBc (2169.61, 1706 and 8.45, respectively; cutoff value: < 1.00) and an HBV viral load of 33212320 IU/mL. CONCLUSION: The present study showed that loss of hepatitis B immunity after liver transplantation is unexpectedly common. In our case report, despite high levels of anti-HBs prior to transplantation, infection occurred at a time when, unfortunately, the child had lost immunity to hepatitis B after liver transplantation.

AB - Nowadays acute gastroenteritis infection caused by Escherichia coli (E. coli) O157:H7 is frequently associated with hemolytic uremic syndrome (HUS), which usually developed after prodromal diarrhea that is often bloody. The abdominal pain accompanied by failure kidney is a suspicious symptom to develop this disorder. Their pathological characteristic is vascular damage which manifested as arteriolar and capillary thrombosis with abnormalities in the endothelium and vessel walls. The major etiological agent of HUS is enterohemorragic (E coli) strain belonging to serotype O157:H7. The lack of papers about HUS associated to gastroenteritis lead us to report this case for explain the symptoms that are uncommon. Furthermore, this report provides some strategies to suspect and make an early diagnosis, besides treatment approach to improving outcomes and prognosis for patients with this disorder.

AB - We introduce new classes of generalized Orlicz-Garling sequences and Orlicz Lorentz sequences by using a sequence of Orlicz functions and difference operator. We show that the Orlicz-Garling sequence space admits a unique 1 subsymmetric basis and a 1-dominated block basic sequence in [Formula: see text]. We also make an effort to prove that every symmetric normalized block Orlicz Garling sequence dominates an Orlicz-Lorentz sequence. Finally, we study some geometric properties of these spaces and establish some inclusion relations between spaces.

PMID- 29456419 TI - Zipf-Mandelbrot law, f-divergences and the Jensen-type interpolating inequalities. AB - Motivated by the method of interpolating inequalities that makes use of the improved Jensen-type inequalities, in this paper we integrate this approach with the well known Zipf-Mandelbrot law applied to various types of f-divergences and distances, such are Kullback-Leibler divergence, Hellinger distance, Bhattacharyya distance (via coefficient), [Formula: see text]-divergence, total variation distance and triangular discrimination. Addressing these applications, we firstly deduce general results of the type for the Csiszar divergence functional from which the listed divergences originate. When presenting the analyzed inequalities for the Zipf-Mandelbrot law, we accentuate its special form, the Zipf law with its specific role in linguistics. We introduce this aspect through the Zipfian word distribution associated to the English and Russian languages, using the obtained bounds for the Kullback-Leibler divergence.

PMID- 29456423 TI - Evaluating the Implementation of the EndoTool Glycemic Control Software System. AB - Purpose: The purpose of this study was to compare achievement of glycemic control on insulin drips before and after the implementation of EndoTool, a glucose management software system used in a community hospital setting. Methods: A retrospective chart review was performed of patients on an insulin drip who were managed before and after implementation of the EndoTool software. Fifty patients were selected for each group. Statistical analyses were run to compare metrics gathered between groups. Results: Patients in the standard care group were on an insulin drip for an average of 23.9 hours compared to 20.9 hours in the EndoTool group (P = 0.38). Hypoglycemia occurred at an average rate of 0.036 events per patient in the standard group and 0.007 events per patient in the EndoTool group (P = 0.17). The average rate of hyperglycemia was 0.358 events per patient in the standard group and 0.283 events per patient in the EndoTool group (P = 0.25). The average time to achieve the blood glucose target was 2.78 and 3.67 hours in the standard and EndoTool groups, respectively (P = 0.27). Total patient values were within target range 45.2% of the time in the standard care group and 47.3% of the time in the EndoTool group (P = 0.71). Conclusion: Analysis of the implementation of EndoTool in the community hospital setting found no statistically significant differences between groups, although rates of hypo- and hyperglycemia showed a trend toward improved safety in the EndoTool group. These results could be attributed to the conservative parameters the hospital set in the initial phase of EndoTool implementation. PMID- 29456422 TI - Understanding the Meaning of Food in People With Type 2 Diabetes Living in Northern Appalachia. AB - Purpose: Food and eating convey memories and feelings and serve important functions in creating and maintaining relationships. Given the increasing rate of diabetes in the United States, research understanding the meaning of food may shed light on how patients negotiate everyday food choices while managing type 2 diabetes. The purpose of this qualitative study was to explore the meaning of food among adults with type 2 diabetes living in Northern Appalachia. Methods: In depth, face-to-face interviews were conducted with type 2 diabetes patients. Interviews were coded and analyzed via thematic analysis. Results: Nineteen adults with type 2 diabetes (mean age 68.7 +/- 10.6 years, mean A1C 7.4 +/- 1.4%, mean diabetes duration 10.9 +/- 11.9 years, 52.6% female, 100% white) participated in the study. Qualitative analysis revealed three themes: 1) "Sustaining Life:" Food and the Demands of Diabetes Management, in which participants described the role of food as operational and said that eating was dictated by time rather than hunger or pleasure; 2) "Diabetes Feels Like a Yield Sign:" Diabetes Changes Perceptions of Food, Enjoyment, and Social Relationships, in which most participants described a negative or ambivalent relationship with food after their diabetes diagnosis; and 3) "Food is Everywhere; It's Seducing:" Struggling With Diabetes Management in a Fast-Food Culture, in which participants discussed how the American fast-food culture was in direct conflict with the demands of diabetes and described how they struggled to follow a healthful diet in a culture that advertised the opposite in many venues. Conclusion: Adults with diabetes may benefit from education that addresses both the personal and sociocultural factors that guide food choices. PMID- 29456424 TI - Diabetes Risk Assessment in Latinas: Effectiveness of a Brief Diabetes Risk Questionnaire for Detecting Prediabetes in a Community-Based Sample. AB - Objective: Numerous validated questionnaires use self-reported data to quantify individuals' risk of having diabetes or developing it in the future. Evaluations of these tools have primarily used nationally representative data, limiting their application in clinical and community settings. This analysis tested the effectiveness of the American Diabetes Association (ADA) risk questionnaire for identifying prediabetes in a community-based sample of Latinas. Methods: Data were collected using the ADA risk questionnaire and assessing A1C. Among 204 participants without diabetes, we examined the association between individual characteristics and glycemic status. We then calculated the performance characteristics (sensitivity, specificity, positive predictive value [PPV], and negative predictive value [NPV]) of the ADA risk questionnaire for detecting prediabetes, using A1C results as the gold standard to define the outcome. Results: All participants were women of self-reported Hispanic/Latino ethnicity. Their mean ADA risk score was 5.6 +/- 1.6. Latinas who had prediabetes were older, with significantly higher rates of hypertension and a higher ADA risk score than those without prediabetes. At a risk score >=5-the threshold for high risk set by the ADA-the questionnaire had the following test performance characteristics: sensitivity 77.8%, specificity 41.7%, PPV 76.2%, and NPV 43.9%. Conclusion: The ADA risk questionnaire demonstrates reasonable performance for identifying prediabetes in a community-based sample of Latinas. Our data may guide other groups' use of this tool in the same target population. Future research should examine the effectiveness of this questionnaire for recruiting diverse populations into diabetes prevention programs. In addition, unique diabetes risk assessment tools for specific target populations are needed and may outperform questionnaires developed using nationally representative data. PMID- 29456425 TI - Reasons for Open and Closed Attitudes Regarding Type 1 Diabetes. AB - Thirty-one adults with type 1 diabetes participated in this qualitative study to explore reasons why they were willing (had an open attitude) or unwilling (had a closed attitude) to disclose diabetes-related information to others. Participants (61.3% female, mean age 38.48 years, mean duration of diabetes 21.94 years, 100% white) answered open-ended questions about living with type 1 diabetes. Interviews were transcribed verbatim and coded to identify major patterns that emerged in the data. Reasons for open attitudes included support from others, confidence and feeling comfortable, feeling normal despite diabetes, seeking to educate, and feeling that it was not a major concern to share information with others. Reasons for closed attitudes included fear of discrimination, misunderstanding from others, embarrassment and shame, and feeling that it was not a major concern to share information. A higher number of participants reported open attitudes after diagnosis than at initial diagnosis; a lower number of participants reported closed attitudes after diagnosis than at initial diagnosis. Professionals should consider effective forms of type 1 diabetes related education to reduce diabetes misconceptions and discrimination against diagnosed individuals. This may help individuals feel more open and willing to adhere to and seek assistance with their diabetes-related self-care. PMID- 29456426 TI - Influences on Diabetes Self-Management Education Participation in a Low-Income, Spanish-Speaking, Latino Population. AB - Objective: To investigate influences on participation in diabetes self-management education (DSME) classes in a low-income, Spanish-speaking, Latino population. Methods: Fifteen patients from an Oregon clinic participated in semi-structured interviews designed to understand influences on their participation in DSME classes, and the authors conducted a thematic analysis. Results: Four themes characterized the data: 1) limited resources, 2) culture, 3) relationship with diabetes, and 4) relationship with clinic. Barriers to class attendance included lack of time, childcare, and transportation; male participants' shame of illness and lack of interest in health; and difficulty contacting participants by telephone. Motivators of class attendance included interest in being healthy for the sake of family; interest in nutrition; knowledge of the effects of diabetes on self, friends, and family; and positive experiences with group support and self-efficacy in class. Practice implications and conclusion: Participation in DSME classes in this low-income, Spanish-speaking, Latino population was influenced by many factors. Understanding these factors is an important step toward creating classes that are successful in increasing attendance rates for this and similar populations. Creative, targeted approaches to designing DSME classes for low-income, Spanish-speaking, Latino patients and similar populations are needed. These may include classes that remove the barriers of shame and lack of interest for male participants; focus on family involvement, celebration of culturally appropriate foods, group support, and self-efficacy; are accessible to resource-limited participants; and use alternative methods to recruit hard-to reach participants. PMID- 29456428 TI - Strategies to Improve Prevention and Management in Diabetic Retinopathy: Qualitative Insights from a Mixed-Methods Study. AB - Nonproliferative and proliferative diabetic retinopathy (DR) are common, progressive complications of diabetes with a rising incidence. Over time, patients with nonproliferative DR may progress to more advanced stages of DR, with an increased risk of vision-threatening conditions such as diabetic macular edema (DME). DME is the most frequent cause of vision loss in patients with diabetes and eventually can lead to blindness. Early-stage DR is asymptomatic; therefore, a coordinated management strategy is crucial to prevent or limit the progression of DR. Such a strategy includes regular screening for DR risk factors, glycemic control, and prompt diagnosis of DR. Preventive care should include a comprehensive dilated eye exam, ancillary tests, and patient education involving a multidisciplinary team composed of ophthalmologists, retina specialists, and primary diabetes care providers, including primary care providers and endocrinologists/diabetologists. However, although guideline recommendations for regular screening and patient education are well disseminated, many people with diabetes are not receiving ophthalmological care that could prevent visual impairment and blindness. We designed a mixed-methods study to explore the impact of patient-focused education on patient knowledge and self-efficacy in relation to DR prevention and management and to assess how online education can help to change patient knowledge, competence, and practice. Analysis of in-depth, qualitative data involving people with diabetes with or without DR collected 5-16 weeks after education participation shows that online patient education is an effective tool in building patient knowledge and awareness about DR and in motivating action in DR self-care. PMID- 29456427 TI - The Experience of Diabetes-Related Language in Diabetes Care. AB - Objective: The goal of this study was to understand how adults with diabetes experience the words used in diabetes care. Methods: This qualitative study guided by Critical Theory used two virtual and two in-person focus groups conducted by the same facilitator. A total of 68 focus group members participated. The facilitator transcribed and coded focus group data using individual responses as the unit of analysis. The facilitator used constant comparison to analyze responses and developed a research summary of themes that emerged. A second coder confirmed the themes originally identified, and participants provided feedback on the summary. Results: Many negative and stigmatizing words are used in diabetes care. Several themes emerged from the data, including judgment; fear and anxiety; labels, reminders, and assumptions; oversimplification and directives; misunderstanding, misinformation, and disconnection; and body language and tone. Participants reported experiencing negative diabetes-related words in the general public, with their health care providers (HCPs), and in the media. Participants made suggestions for HCPs to replace negative words; they raised a concern that current negative words will be replaced by others with similar negative connotations; and they said they would feel more like a partner in their care if HCPs stopped using these words. Conclusion: The language used in diabetes care has an impact on people who live with the disease. Awareness is the first step in eradicating stigma in diabetes care. HCPs can improve patient-provider communication and contribute to a more positive experience for people living with diabetes by choosing words that empower. PMID- 29456429 TI - Influence of Health Status on the Association Between Diabetes and Depression Among Adults in Europe: Findings From the SHARE International Survey. AB - Objective: The association between diabetes and depression, a common health comorbidity in people with diabetes, has been recognized but not well understood. The purpose of this study was to explore the association between diabetes and depression in a large international sample of adults, adjusting for demographics, socioeconomic status, behavioral risks, and current health status. Methods: The association between diabetes and depression was assessed in a sample of 57,004 Europeans >=50 years of age from 15 European countries using data from the fifth wave of SHARE (the Survey of Health, Ageing, and Retirement in Europe). Multiple logistic regression models of the association between diabetes and depression were conducted, adjusting for potential confounders. Results: Analyses showed that, despite diabetes being associated with depression in crude and partially adjusted models, further adjustment for self-perceived health made the association between diabetes and depression no longer statistically significant (odds ratio 1.0, 95% CI 0.9-1.0). Conclusion: Adjustment for a variety of demographic, socioeconomic, behavioral risk, and health status variables reduced the estimated association between diabetes and depression until it was no longer significant. Further research should explore the specific symptoms of distress characterized in people with diabetes. PMID- 29456430 TI - Effect of Medical Nutrition Therapy for Patients With Type 2 Diabetes in a Low /No-Cost Clinic: A Propensity Score-Matched Cohort Study. AB - Background: Although many studies have been conducted regarding the effectiveness of medical nutrition therapy (MNT) for type 2 diabetes management, less is known about the effectiveness of MNT for low-income adults. This study evaluated the contribution of MNT in improving A1C and blood pressure in a population of low income adults with type 2 diabetes. Methods: This was a population-based, propensity score-matched cohort study using provincial health data from Altoona, Blair County, Pa. Patients who had been diagnosed with type 2 diabetes for at least 6 months before March 2014 were selected from two separate clinics that serve low-income populations. Patients who received MNT (n = 81) from a registered dietitian were compared to a matched group of patients who received primary care alone (n = 143). Outcome measures were A1C and systolic and diastolic blood pressure. The follow-up period was 1 year. Results: Improvements in A1C and systolic and diastolic blood pressure were statistically significant for patients who received MNT at uniform 3-month intervals through 1 year. At the 1-year follow-up, A1C reduction was -0.8% (P <0.01), systolic blood pressure reduction was -8.2 mmHg (P <0.01), and diastolic blood pressure reduction was 4.3 mmHg (P <0.05). Conclusion: Although low-income individuals encounter a variety of barriers that reduce their capacity for success with and adherence to MNT, provision of nutrition therapy services by a registered dietitian experienced in addressing these barriers can be an effective addition to the existing medical components of type 2 diabetes care.

PMID- 29456436 TI - Learning Activity Predictors from Sensor Data: Algorithms, Evaluation, and Applications. AB - Recent progress in Internet of Things (IoT) platforms has allowed us to collect large amounts of sensing data. However, there are significant challenges in converting this large-scale sensing data into decisions for real-world applications. Motivated by applications like health monitoring and intervention and home automation we consider a novel problem called Activity Prediction, where the goal is to predict future activity occurrence times from sensor data. In this paper, we make three main contributions. First, we formulate and solve the activity prediction problem in the framework of imitation learning and reduce it to a simple regression learning problem. This approach allows us to leverage powerful regression learners that can reason about the relational structure of the problem with negligible computational overhead. Second, we present several metrics to evaluate activity predictors in the context of real-world applications. Third, we evaluate our approach using real sensor data collected from 24 smart home testbeds. We also embed the learned predictor into a mobile device-based activity prompter and evaluate the app for 9 participants living in smart homes. Our results indicate that our activity predictor performs better than the baseline methods, and offers a simple approach for predicting activities from sensor data. PMID- 29456437 TI - A Tabletop Persistent-Mode, Liquid-Helium-Free, 1.5-T/90-mm MgB2 "Finger" MRI Magnet for Osteoporosis Screening: Two Design Options. AB - In this paper we present two design options for a tabletop liquid-helium-free, persistent-mode 1.5-T/90-mm MgB2 "finger" MRI magnet for osteoporosis screening. Both designs, one with and the other without an iron yoke, satisfy the following criteria: 1) 1.5-T center field with a 90-mm room-temperature bore for a finger to be placed at the magnet center; 2) spatial field homogeneity of <5 ppm over a 20-mm diameter of spherical volume (DSV); 3) persistent-mode operation with temporal stability of <0.1 ppm/hr; 4) liquid-helium-free operation; 5) 5-gauss fringe field radius of <50 cm from the magnet center; and 6) small and light enough for placement on an exam table. Although the magnet is designed to operate nominally at 10 K, maintained by a cryocooler, it has a 5-K temperature margin to keep its 1.5-T persistent field up to 15 K. The magnet will be immersed in a volume of solid nitrogen (SN2) that provides additional thermal mass when the cryocooler is switched off to provide a vibration-free measurement environment. The SN2 enables the magnet to maintain its persistent field over a period of time sufficient for quiescent measurement, while still limiting the magnet operating temperature to <=15 K. We discuss first pros and cons of each design, and then further studies of our proposed MgB2 finger MRI magnet. PMID- 29456438 TI - Barriers to Participation in Parenting Programs: The Relationship between Parenting Stress, Perceived Barriers, and Program Completion. AB - Families experiencing child maltreatment or risk factors for child maltreatment often receive referrals to interventions focused on changing parenting practices. Compliance with specific parenting programs can be challenging as many of the stressors that place families at-risk may also interfere with program participation. Because families may receive limited benefit from programs they do not fully receive, it is critical to understand the relationship between parenting stress and barriers to program completion. We used structural equation modeling to examine the relationship among parenting stress, perceived barriers to program participation, and program completion in two datasets involving low income parents. Data were collected at two time points from a sample of parents involved with child welfare services and a sample of parents considered at-risk of future involvement (total study n = 803). Direct paths from parenting stress at time 1 to barriers to participation and parenting stress at time 2, and from parenting stress at time 2 to program completion were significant. Interestingly, increased barriers to participation were related to increased parenting stress at time 2, and greater parenting stress was related to increased program completion. Results suggest that with increasing levels of parenting stress, parents have an increased likelihood of completing the program. Assessing and addressing the influence of perceived barriers and parenting stress on program participation may decrease the likelihood of treatment attrition. PMID- 29456439 TI - Parent Training and Skill Acquisition and Utilization Among Spanish- and English Speaking Latino Families. AB - In the U.S., there is a growing Latino population, in which parents primarily speak Spanish to their children. Despite the evidence that language preference is associated with level of acculturation and influences parenting practices in these families, no study has compared how Spanish-and English-speaking Latino families acquire and utilize the skills taught during parent-training programs such as Parent-Child Interaction Therapy (PCIT). Twenty-seven mother-infant Latino dyads received a home-based adaptation of the Child-Directed Interaction (CDI) phase of PCIT as part of a larger randomized control trial. Most infants were male (63%), and their average age was 13.7 months (SD = 1.43). Most families (52%) lived below the poverty line. The Dyadic Parent-Child Interaction Coding System-Third Edition (DPICS-III) was employed to evaluate PCIT skills at baseline and post-treatment, as well as at 3- and 6-month follow-up, assessments. We conducted multiple linear regression analyses among Spanish-speaking (55%) and English-speaking (45%) families to examine differences in acquisition and utilization of do and don't skills at each assessment while controlling for mother's education. Results yielded no group differences in the acquisition rate of do or don't skills at any time point. However, Spanish-speaking mothers used significantly more don't skills than English-speaking mothers at each assessment. Specifically, Spanish-speaking families used significantly more commands at baseline, post-treatment, and the 6-month followup assessments, as well as more questions at post-treatment and at the 6-month follow-up assessments. These findings highlight the importance of addressing cultural values such as respeto to ensure culturally robust parent-training programs for Latino families.

PMID- 29456440 TI - Maltreated Children Use More Grammatical Negations. AB - Many studies reveal a strong impact of childhood maltreatment on language development, mainly resulting in shorter utterances, less rich vocabulary, or a delay in grammatical complexity. However, different theories suggest the possibility for resilience-a positive adaptation to an otherwise adverse environment-in children who experienced childhood maltreatment. Here, we investigated different measures for language development in spontaneous speech, examining whether childhood maltreatment leads to a language deficit only or whether it can also result in differences in language use due to a possible adaptation to a toxic environment. We compared spontaneous speech during therapeutic peer-play sessions of 32 maltreated and 32 non-maltreated children from the same preschool and equivalent in gender, age (2 to 5 years), home neighborhood, ethnicity, and family income. Maltreatment status was reported by formal child protection reports, and corroborated by independent social service reports. We investigated general language sophistication (i.e., vocabulary, talkativeness, mean length of utterance), as well as grammatical development (i.e., use of plurals, tense, grammatical negations). We found that maltreated and non-maltreated children showed similar sophistication across all linguistic measures, except for the use of grammatical negations. Maltreated children used twice as many grammatical negations as non-maltreated children. The use of this highly complex grammatical structure shows an advanced linguistic skill, which shows that childhood maltreatment does not necessarily lead to a language deficit. The result might indicate the development of a negativity bias in the structure of spontaneous language due to an adaptation to their experiences. PMID- 29456442 TI - The effect of direction specific thoracic spine manipulation on the cervical spine: a randomized controlled trial. AB - Objectives: To determine the difference on neck outcomes with directional manipulation to the thoracic spine. There is evidence that thoracic spine manipulation is effective in treating patients with neck pain. However, there is no research that determines if the assessment of directional hypomobility and the selection of thrust direction offer improved outcomes. Methods: A total of 69 patients with cervical spine pain were randomly assigned to receive either a manipulation that was consistent with their thoracic spine motion loss (matched) or opposite their motion loss (unmatched). The patient was given care consistent with the orthopedic section guidelines for neck pain and the physical therapist's clinical reasoning. Baseline outcome measures (NPRS, NDI, GROC) were taken and reassessed two days and two weeks after treatment. Results: Both groups had positive results when pain, neck disability index, and global rating of change were assessed. There was no difference between the matched and unmatched groups. Discussion: Directional manipulation of hypomobile thoracic spine segments may not be required to improved outcomes in patients with neck pain. Future studies should assess a variety of factors when determining the best available treatment, including manual therapy procedures, exercise, and patient selection. Level of Evidence: 1b. PMID- 29456443 TI - The screening process of a patient with low back pain and suspected thoracic myelopathy: a case report. AB - Background: Thoracic disc herniations are rare and difficult to diagnose. Myelopathy is a potential consequence that can lead to irreversible neurological impairment if not treated appropriately. It is incumbent on all clinicians who see patients with low back pain (LBP) to be aware of such pathologies. This case describes a screening process in the detection of a rare serious spinal pathology and discusses the use of red flags and central nervous system signs and symptoms in the decision leading to immediate referral. Case Description: The subject in this case was a 69-year-old male referred to physical therapy for the treatment of LBP after having seen two medical doctors. He presented with severe spinal pain with gait disturbance, postural balance deficits and bilateral loss of plantar flexor strength. Decreased sensation in the buttocks and a subtle episode of urinary incontinence were also present. Outcomes: Based on the results of the history and physical examination, the patient was referred back to his medical practitioner, who ordered magnetic resonance imaging. A thoracic disc herniation associated with spondyloarthritis at T10-11 causing myelopathy was detected, and the patient underwent immediate decompressive surgery. One month following initial evaluation, the patient had completely recovered without any neurological compromise. Discussion: This case highlights the importance of the screening of serious pathologies and the assessment of central nervous impairments in certain cases of LBP. The integration of a cluster of subjective and physical examination findings led to the prompt referral of this patient for urgent medical attention. Level of Evidence: 4. PMID- 29456444 TI - Pain pattern classification and directional preference are associated with clinical outcomes for patients with low back pain. AB - Pain Pattern Classification (PPC) and Directional Preference (DP) have shown merit as reliable and predictable clinical solutions to help reduce the burden posed by low back pain (LBP). We conducted a prospective, observational cohort study to verify the association between PPC, DP, and clinical outcomes. We hypothesized that (1) patients who demonstrated DP Centralization (CEN) would have lower pain intensity and disability at follow-up than patients who demonstrated Non-DP Non-CEN, and (2) the prevalence of DP at first examination would be lowest for patients with chronic LBP and are greater than 65 years old. First examination and follow-up data were completed by 639 patients. Clinical outcome measures, including pain intensity and disability, were collected at first examination and follow-up. Baseline comparisons were made between groups with first examination data only and groups with first examination data and follow-up data. A Pearson's chi-squared test was used to determine differences in prevalence rates for the categorical variables, and two-sample t-tests were used for the continuous variables. A Turkey's range test was used to determine differences in follow-up pain intensity and disability for LBP dual classifications. Multiple regression was used to investigate DP prevalence considering risk adjusted factors. Overall prevalence of DP was 84.5% and prevalence was lowest for patients with sub-acute symptoms. No significant difference existed for the prevalence of DP for patients based on age. Patients classified as DP CEN had, on average, 1.99 pain intensity units less than patients classified as Non-DP Non-CEN at follow-up. Patients classified as DP CEN had, on average, 3.43 RMDQ units less than patients classified as Non-DP Non-CEN at follow-up.These findings support previous reports, verifying the association between LBP dual-classification schemes and clinical outcomes. PMID- 29456446 TI - Prevalence and reliability of treatment-based classification for subgrouping patients with low back pain. AB - Objectives: To observe the distribution of patients who presented with low back pain (LBP) and to determine the between therapists' interrater reliability of assessments in a private outpatient setting using treatment-based classification (TBC) subgroups. Methods: An observational and methodological study was conducted. Four hundred and twenty-nine patients (231 male; 198 female) presenting LBP symptoms and referred to conservative treatment were assessed by 13 physical therapists who conducted a 60-min examination process utilizing TBC subgroups. Interrater reliability analyses from six raters were assessed using Fleiss' kappa and previously recorded data (n = 30). Results: In this study, 65.74% of patients were classified in only one subgroup, the most prevalent being stabilization (21.91%), followed by extension (15.38%), traction (11.89%), flexion (10.96%), manipulation (5.13%), and lateral shift (0.47%). Approximately 20.98% of patients were classified in two subgroups, where the most frequent overlaps were flexion + stabilization (7.46%), extension + stabilization (6.06%), flexion + traction (4.20%), extension + manipulation (1.86%), and 13.29% of patients were not classified in any TBC subgroup. Analysis of interrater reliability showed a kappa value of 0.62 and an overall agreement of 66% between raters. Discussion: LBP is a heterogeneous clinical condition and several classification methods are proposed in the attempt to observe better outcomes for patients. Eighty-five percent of patients assessed were able to be classified when using the TBC assessment and reliability analysis showed a substantial agreement between raters. Level of Evidence: 2c. PMID- 29456445 TI - Concurrent validation of a pressure pain threshold scale for individuals with myofascial pain syndrome and fibromyalgia. AB - Background: Manual pressure palpation is an examination technique used in the classification of myofascial pain syndrome (MPS) and fibromyalgia (FM). Currently, there are no validated systems for classifying results. A valid and reliable pressure pain threshold scale (PPTS) may provide a means for clinicians to grade, document, and report findings. The purpose of this investigation was to validate a PPTS in individuals diagnosed with MPS and FM. Intra-rater reliability, concurrent validity, minimum cut-off value, and patient responses were evaluated. Methods: Eighty-four participants who met the inclusion criteria were placed into three groups of 28 (N = 84): MPS, FM, and asymptomatic controls. All participants underwent a two-part testing session using the American College of Rheumatology criteria for classifying FM. Part-1 consisted of manual palpation with a digital pressure sensor for pressure consistency and part 2 consisted of algometry. For each tender point (18 total), participants graded tenderness using the visual analog scale (VAS) while the examiner concurrently graded response using a five-point PPTS. Results: The PPTS had good intra-rater reliability (ICC >= .88). A moderate to excellent relationship was found between the PPTS and VAS for all groups with the digital pressure sensor and algometer (rho >= .61). A minimum cut-off value of 2 on the PPTS differentiated participants with MPS and FM from asymptomatic controls. Discussion: The results provide preliminary evidence validating the PPTS for individuals with MPS and FM. Future research should further study the clinimetric properties of the PPTS with other chronic pain and orthopedic conditions. Levels of Evidence: 2c. Clinical Trial Registration: ClinicalTrials.gov registration No. NCT02802202. PMID- 29456447 TI - A preliminary analysis of outcomes and end range procedures used to achieve centralization in people with low back pain. AB - Objectives: To investigate the relationship between clinical outcome and the types of end range procedures used to achieve centralization in a sample of patients with low back pain (LBP) and/or peripheral symptoms. Methods: Small sample retrospective analysis of an observational cohort. Patients with LBP who centralized during initial visit at two physical therapy clinics were recruited to participate. The types of end range procedures used to achieve centralization were documented during each office visit and a chart review was performed after 4 weeks. Outcomes were determined by improvement in the Oswestry Disability Index (ODI) score after 4 weeks. Statistical analysis determined the association between the types of end range procedures and outcomes. Results: Thirty-one patients gave consent to participate. Nineteen patients met inclusion criteria and were included in data analysis. After 4 weeks, the improvement in mean ODI scores was 15.89 +/- 16.28. Differing end range procedures were used to achieve centralization within this cohort. The types of end range procedures used to achieve centralization were not significantly associated with outcomes. Discussion: The results observed in this study promote exhausting many different types of end range procedures to determine if centralization can be achieved. Limiting the end range procedures used to assess centralization may fail to identify patients who can achieve centralization and subsequently have positive clinical outcomes. Larger cohort studies investigating relationships between outcomes and the types of end range procedures used to achieve centralization would contribute to management of people with LBP.

AB - Objective: There is an extensive relationship between chronic pain and depression; however, there is less research examining whether pain-specific factors, such as pain intensity, predict depression, above and beyond the role of normative factors, such as positive emotions. The current study characterized the independent contributions of pain intensity, pain catastrophizing, and a trait measure of happiness to self-rated depressive symptoms. Methods: We recruited and enrolled 70 volunteers across 3 groups of participants: two groups of patients with current low back pain (one group on opioids and one group opioid-naive), and individuals in a methadone maintenance treatment program. Results: Of note, participants reporting concurrent opioid use reported significantly higher levels of depressive symptomatology, although study groups did not differ on any other clinical variables. In our path model, we failed to find direct relationships between pain (intensity or duration) and either trait happiness or depressive symptoms (p > .05). However, our analysis did reveal that individuals with chronic back pain who reported higher levels of trait happiness reported lower levels of depressive symptomatology; this effect was significantly mediated by lower levels of pain catastrophizing (standardized ab = -.144, p = .002). Conclusion: Our analysis suggests that trait happiness, while unrelated to ongoing pain, may predict a decreased vulnerability to depressive symptoms in individuals with chronic pain, which may operate via lower levels of pain catastrophizing.

AB - Background: Herbal medicine (HM) regulation is less developed than that of allopathic medicines, with some countries lacking specific regulations. Objective: For the purpose of informing a registration system for HMs in Kuwait, which does not manufacture but imports all HMs, this study compared the similarities and differences between the current HM registration systems of five countries. Methods: The five countries were selected as major source countries of HM in Kuwait (United Kingdom (UK), Germany and United States of America (USA)) or because of geographical proximity or size and approach (United Arab Emirates (UAE) and Kingdom of Bahrain). Documentary analysis of HM classification systems was performed by reviewing the regulatory and law documentation of these countries' drug regulatory authority websites. Data on HM definition, classification and the main requirements for registration were extracted and analysed for similarities and differences. Results: There was diversity in the classification of HMs across all five countries including terms used, definitions, type of law, requirements, restrictions and preparation type. The regulatory authorities of the UK, Germany, UAE and Kingdom of Bahrain offer simplified registration for HMs, where plausible efficacy as a result of established traditional use is sufficient. In USA, the concept of traditional use does not exist, instead, the product can be categorised as a dietary supplement where no assessment or evaluation is required prior to marketing. Conclusions: Owing to the inconsistencies in how drug regulatory authorities define HMs, it will be important to design a clear definition of what constitutes a HM in Kuwait, which is a country that does not produce and register its own products but assesses products registered elsewhere. PMID- 29456450 TI - Survey on patient safety culture in the Republic of Moldova: a baseline study in three healthcare settings. AB - Background and aims: The Republic of Moldova is a small ex-soviet country in the Central Eastern European group of states, whose official language is Romanian. In countries with limited resources, quality improvement in healthcare and patient safety are very challenging. This study aims to identify which areas of the patient safety culture (PSC) need prompt intervention. Methods: A cross-sectional study was conducted in three Moldovan healthcare settings, using the Romanian translation of the US Hospital Survey on Patient Safety Culture HSOPSC. Descriptive statistics were carried out, based on the responses from n. 929 staff. Percentages of positive responses (PPRs) by item (41 items) and composite (12 PSC areas) were computed. Results: Most respondents were nurses (53%), followed by doctors (35%). The main work areas were: primary care (27%), medical specialties (20%), gynecology and obstetrics (16%), and general surgery (11%). The highest composite PPRs were for: teamwork within units (80%), feedback & communication about error, organizational learning-continuous improvement and supervisor/manager expectations & actions promoting patient safety (78%), and management support for patient safety (75%). The lowest composites were for: frequency of events reported (57%), non-punitive response to errors (53%), communication openness (51%) and staffing (37%). Conclusion: Our results suggest that staffing issues should be tackled to provide safe care. Staff avoid to openly report adverse events and/or discuss errors, likely because a poor understanding of the potential of these events for learning and because of fear of blame or punitive actions. Future research should check psychometrics of the Romanian version of the HSOPSC applied to Moldovan staff. PMID- 29456451 TI - Human beta-defensin-2 gene transduction of dental pulp cells: A model for pulp antimicrobial gene therapy. AB - The objective of this study was to determine whether cells from human pulp can be transduced to express the antimicrobial peptide--human beta-defensin-2 (HBD-2). Primary human pulp cells and gingival fibroblasts from normal tissue, as well as two mouse cell lines (NIH 3T3 and AT-84) and a human cell line SCC-9 were transduced with a retroviral vector carrying HBD-2 cDNA. ELISA and Northern blot analyses were performed to detect HBD-2 expression by these transduced cells. Antimicrobail assays using recombinant HBD-2 were performed on two caries associated bacteria Streptococcus mutnas and Lactobacillus acidophilus. The results showed that transduced pulp cells secreted 62.4 +/- 27.2 ng/3 days of HBD 2, which was comparable to that by NIH 3T3 (78.0 +/- 14.1 ng/4 days), and higher than those by gingival fibroblasts (17.9 +/- 7.9 ng/3 days), AT-84 (2.6 +/- 1.0 ng/3 days), and SCC-9 (47.6 +/- 9.9 ng/3 days). Northern blot analysis showed that the levels of HBD-2 mRNA expression correlated with their protein secretion levels. There was approximately 50% reduction of growth when S. mutans and L. acidophilus were exposed to HBD-2 at 1 uM. Pulp cells appear to be suitable for HBD-2 transduction using retroviral vectors, suggesting a potential for use in controlling pulpal infections. PMID- 29456452 TI - Factors associated with NO2 and NOX concentration gradients near a highway. AB - The objective of this research is to learn how the near-road gradient, in which NO2 and NOX (NO + NO2) concentrations are elevated, varies with changes in meteorological and traffic variables. Measurements of NO2 and NOX were obtained east of I-15 in Las Vegas and fit to functions whose slopes (dCNO2 /dx and dCNOX /dx, respectively) characterize the size of the near-road zone where NO2 and NOX concentrations from mobile sources on the highway are elevated. These metrics were used to learn about the near-road gradient by modeling dCNO2 /dx and dCNOX /dx as functions of meteorological variables (e.g., wind direction, wind speed), traffic (vehicle count), NOX concentration upwind of the road, and O3 concentration at two fixed-site ambient monitors. Generalized additive models (GAM) were used to model dCNO2 /dx and dCNOX /dx versus the independent variables because they allowed for nonlinearity of the variables being compared. When data from all wind directions were included in the analysis, variability in O3 concentration comprised the largest proportion of variability in dCNO2 /dx, followed by variability in wind direction. In a second analysis constrained to winds from the west, variability in O3 concentration remained the largest contributor to variability in dCNO2 /dx, but the relative contribution of variability in wind speed to variability in dCNO2 /dx increased relative to its contribution for the all-wind analysis. When data from all wind directions were analyzed, variability in wind direction was by far the largest contributor to variability in dCNOX /dx, with smaller contributions from hour of day and upwind NOX concentration. When only winds from the west were analyzed, variability in upwind NOX concentration, wind speed, hour of day, and traffic count all were associated with variability in dCNOX /dx. Increases in O3 concentration were associated with increased magnitude near-road dCNO2 /dx, possibly shrinking the zone of elevated concentrations occurring near roads. Wind direction parallel to the highway was also related to an increased magnitude of both dCNO2 /dx and dCNOX /dx, again likely shrinking the zone of elevated concentrations occurring near roads. Wind direction perpendicular to the road decreased the magnitude of dCNO2 /dx and dCNOX /dx and likely contributed to growth of the zone of elevated concentrations occurring near roads. Thus, variability in near-road concentrations is influenced by local meteorology and ambient O3 concentration. PMID- 29456453 TI - Exploring the relevance of spatial scale to life cycle inventory results using environmentally-extended input-output models of the United States. AB - The accuracy of direct and indirect resource use and emissions of products as quantified in life cycle models depends in part upon the geographical and technological representativeness of the production models. Production conditions vary not just between nations, but also within national boundaries. Understanding the level of geographic resolution within large industrial nations needed to reach acceptable accuracy has not been well-tested across the broad spectrum of goods and services consumed. Using an aggregate 15-industryenvironmentally extended input-output model of the US along with detailed interstate commodity flow data, we test the accuracy of regionalizing the national model into two regions (state - rest of US) versus 51 regions (all US states + DC). Our findings show the two-region form predicts life cycle emissions and resources used within 10-20% of the more detailed 51-region form for most of the environmental flows studied. The two-region form is less accurate when higher variability exists in production conditions for a product. PMID- 29456454 TI - Putting trapped populations into place: Climate change and inter-district migration flows in Zambia. AB - Research shows that the association between adverse climate conditions and human migration is heterogeneous. One reason for this heterogeneity is the differential vulnerability of populations to climate change. This includes highly vulnerable, "trapped" populations that are too poor to migrate given deep and persistent poverty, the financial costs of migrating, and the erosion of already fragile economic livelihoods under climate change. Another reason for this heterogeneity is the differential vulnerability of places. However, despite the growing list of studies showing that the climate-migration relationship clearly varies across places, there is surprisingly little research on the characteristics of places themselves that trap, or immobilize, populations. Accordingly, we provide the first account of the "holding power" of places in the association between adverse climate conditions and migration flows among 55 districts in Zambia in 2000 and 2010. Methodologically, we combine high resolution climate information with aggregated census micro data to estimate gravity models of inter-district migration flows. Results reveal that the association between adverse climate conditions and migration is positive only for wealthy migrant-sending districts. In contrast, poor districts are characterized by climate-related immobility. Yet, our findings show that access to migrant networks enables climate related mobility in the poorest districts, suggesting a viable pathway to overcome mobility constraints. Planners and policy makers need to recognize the holding power of places that can trap populations and develop programs to support in situ adaptation and to facilitate migration to avoid humanitarian emergencies. PMID- 29456455 TI - Resilient futures of a small island: A participatory approach in Tenerife (Canary Islands) to address climate change. AB - Adaptation to climate change has been considered to be crucial to current societies, especially for small islands. In this paper the case of Tenerife (in the Canary Islands) is analysed. Tenerife is a small island located northwest of the African continent, in the Atlantic Ocean. Tenerife presents a high vulnerability to heatwaves and Saharan dust events as a consequence of its closeness to the Saharan desert. In fact, increasing frequency of heatwaves and Saharan dust events has been reported and could worsen in the future due to global warming. An exploration of adaptation strategies to an increase of the frequency and intensity of these phenomena is therefore needed. Different social actors have been engaged in a participatory process aiming at exploring pathways for adaptation to extreme weather events. Resilience was argued as the relevant framing to address those hazards. Four focus group sessions were carried out in order to explore key transformative elements necessary to make resilient futures for Tenerife. The results highlight the need for broader climate-based policies across all sectors to assure that the island becomes resilient to climatic and non-climatic shocks. PMID- 29456456 TI - Developing and evaluating an instrument to measure Recovery After INtensive care: the RAIN instrument. AB - Background: Measuring and evaluating patients' recovery, following intensive care, is essential for assessing their recovery process. By using a questionnaire, which includes spiritual and existential aspects, possibilities for identifying appropriate nursing care activities may be facilitated. The study describes the development and evaluation of a recovery questionnaire and its validity and reliability. Methods: A questionnaire consisting of 30 items on a 5 point Likert scale was completed by 169 patients (103 men, 66 women), 18 years or older (m=69, SD 12.5) at 2, 6, 12 or 24 months following discharge from an ICU. An exploratory factor analysis, including a principal component analysis with orthogonal varimax rotation, was conducted. Ten initial items, with loadings below 0.40, were removed. The internal item/scale structure obtained in the principal component analysis was tested in relation to convergent and discrimination validity with a multi-trait analysis. Items consistency and reliability were assessed by Cronbach's alpha and internal item consistency. Test of scale quality, the proportion of missing values and respondents' scoring at maximum and minimum levels were also conducted. Results: A total of 20 items in six factors - forward looking, supporting relations, existential ruminations, revaluation of life, physical and mental strength and need of social support were extracted with eigen values above one. Together, they explained 75% of the variance. The half-scale criterion showed that the proportion of incomplete scale scores ranged from 0% to 4.3%. When testing the scale's ability to differentiate between levels of the assessed concept, we found that the observed range of scale scores covered the theoretical range. Substantial proportions of respondents, who scored at the ceiling for forward looking and supporting relations and at floor for the need of social support, were found. These findings should be further investigated. Conclusion: The factor analysis, including discriminant validity and the mean value for the item correlations, was found to be excellent. The RAIN instrument could be used to assess recovery following intensive care. It could provide post-ICU clinics and community/primary healthcare nurses with valuable information on which areas patients may need more support. PMID- 29456457 TI - Effect of ovarian cancer ascites on SKOV-3 cells proteome: new proteins associated with aggressive phenotype in epithelial ovarian cancer. AB - Background: Epithelial ovarian cancer is the second most lethal gynecological cancer worldwide. Ascites can be found in all clinical stages, however in advanced disease stages IIIC and IV it is more frequent and could be massive, associated with worse prognosis. Due to the above, it was our interest to understanding how the ascites of ovarian cancer patients induces the mechanisms by which the cells present in it acquire a more aggressive phenotype and to know new proteins associated to this process. Methods: A proteomic analysis of SKOV-3 cells treated with five different EOC ascites was performed by two-dimensional electrophoresis coupled to MALDI-TOF. The level of expression of the proteins of interest was validated by RT-PCR because several of these proteins have only been reported at the messenger level. Results: Among the proteins identified that increased their expression in ascites-treated SKOV-3 cells, were Ran GTPase, ZNF268, and Synaptotagmin like-3. On the other hand, proteins that were negatively regulated by ascites were HLA-I, HSPB1, ARF1, Synaptotagmin 1, and hnRNPH1, among others. Furthermore, an interactome for every one of these proteins was done in order to identify biological processes, molecular actions, and cellular components in which they may participate. Conclusions: Identified proteins participate in cellular processes highly relevant to the aggressive phenotype such as nuclear transport, regulation of gene expression, vesicular trafficking, evasion of the immune response, invasion, metastasis, and in resistance to chemotherapy. These proteins may represent a source of information which has the potential to be evaluated for the design of therapies directed against these malignant cells that reside on ovarian cancer ascites. PMID- 29456459 TI - How to Interpret PubMed Queries and Why It Matters. AB - A significant fraction of queries in PubMedTM are multiterm queries without parsing instructions. Generally, search engines interpret such queries as collections of terms, and handle them as a Boolean conjunction of these terms. However, analysis of queries in PubMedTM indicates that many such queries are meaningful phrases, rather than simple collections of terms. In this study, we examine whether or not it makes a difference, in terms of retrieval quality, if such queries are interpreted as a phrase or as a conjunction of query terms. And, if it does, what is the optimal way of searching with such queries. To address the question, we developed an automated retrieval evaluation method, based on machine learning techniques, that enables us to evaluate and compare various retrieval outcomes. We show that the class of records that contain all the search terms, but not the phrase, qualitatively differs from the class of records containing the phrase. We also show that the difference is systematic, depending on the proximity of query terms to each other within the record. Based on these results, one can establish the best retrieval order for the records. Our findings are consistent with studies in proximity searching. PMID- 29456458 TI - Proteomic identification and characterization of hepatic glyoxalase 1 dysregulation in non-alcoholic fatty liver disease. AB - Background: Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease worldwide. However, its molecular pathogenesis is incompletely characterized and clinical biomarkers remain scarce. The aims of these experiments were to identify and characterize liver protein alterations in an animal model of early, diet-related, liver injury and to assess novel candidate biomarkers in NAFLD patients. Methods: Liver membrane and cytosolic protein fractions from high fat fed apolipoprotein E knockout (ApoE-/-) animals were analyzed by quantitative proteomics, utilizing isobaric tags for relative and absolute quantitation (iTRAQ) combined with nano-liquid chromatography and tandem mass spectrometry (nLC-MS/MS). Differential protein expression was confirmed independently by immunoblotting and immunohistochemistry in both murine tissue and biopsies from paediatric NAFLD patients. Candidate biomarkers were analyzed by enzyme-linked immunosorbent assay in serum from adult NAFLD patients. Results: Through proteomic profiling, we identified decreased expression of hepatic glyoxalase 1 (GLO1) in a murine model. GLO1 protein expression was also found altered in tissue biopsies from paediatric NAFLD patients. In vitro experiments demonstrated that, in response to lipid loading in hepatocytes, GLO1 is first hyperacetylated then ubiquitinated and degraded, leading to an increase in reactive methylglyoxal. In a cohort of 59 biopsy-confirmed adult NAFLD patients, increased serum levels of the primary methylglyoxal-derived advanced glycation endproduct, hydroimidazolone (MG-H1) were significantly correlated with body mass index (r = 0.520, p < 0.0001). Conclusion: Collectively these results demonstrate the dysregulation of GLO1 in NAFLD and implicate the acetylation-ubquitination degradation pathway as the functional mechanism. Further investigation of the role of GLO1 in the molecular pathogenesis of NAFLD is warranted. PMID- 29456460 TI - The Hamming Ball Sampler. AB - We introduce the Hamming ball sampler, a novel Markov chain Monte Carlo algorithm, for efficient inference in statistical models involving high dimensional discrete state spaces. The sampling scheme uses an auxiliary variable construction that adaptively truncates the model space allowing iterative exploration of the full model space. The approach generalizes conventional Gibbs sampling schemes for discrete spaces and provides an intuitive means for user controlled balance between statistical efficiency and computational tractability. We illustrate the generic utility of our sampling algorithm through application to a range of statistical models. Supplementary materials for this article are available online. PMID- 29456461 TI - Factors Associated with Money Mismanagement Among Adults with Severe Mental Illness and Substance Abuse. AB - People with severe mental illness often have substantial problems with money mismanagement such as losing or lending money to other people and making impulsive or unnecessary purchases, including drugs and alcohol. Money mismanagement in turn affects patients' health and social functioning, and can lead to homelessness and other harm. This cross-sectional study evaluated demographic and clinical predictors of money mismanagement among SSI/SSDI recipients. SSI/SSDI beneficiaries (N = 95) with recent cocaine use initiating a clinical trial were assessed at intake with demographic, cognitive, psychiatric, social/family, substance abuse, and financial measures. In multivariate regression analyses, psychiatric functioning and drug dependence diagnosis were independent predictors of self-reported money mismanagement. Even within individuals whom all had recently used cocaine, those with drug dependence and those with more psychiatric symptomatology had more difficulty managing their funds. Future studies might determine whether people who reduce their drug use and psychiatric symptomatology go on to better manage their funds. PMID- 29456462 TI - Taking Sides in E-cigarette Research. AB - In the last ten years, an eclectic mix of electronic nicotine delivery products ('e-cigarettes') and practices have proliferated in the US with little restriction, producing a vast array of vaping mechanisms, flavors, and styles. At the same time, anti-tobacco movements have targeted e-cigarettes as a threat to public health and advocated for restricting e-cigarettes in much the same way as conventional cigarettes. While anti-vaping proponents associated with public health movements have typically regarded e-cigarettes as primarily harmful products that should be suppressed, vaping advocates regard e-cigarettes as harm reduction products that should be readily accessible to smokers. Distrust between these two warring "sides" animates the controversy over e-cigarettes. In our role as researchers conducting a qualitative study on e-cigarette use, we encountered suspicion and anger from members of an e-cigarette forum who felt that pro-vaping perspectives were often misrepresented by researchers. As a result, we dropped our initial plan to host a group discussion of questions directly related to our study on the forum. Nevertheless, the incident illuminated how vaping advocates have resisted dominant narratives regarding tobacco and nicotine use, destabilized nicotine product categories and challenged interpretations of nicotine use that dichotomize pleasure and health. PMID- 29456463 TI - Income and Child Maltreatment in Unmarried Families: Evidence from the Earned Income Tax Credit. AB - This study estimates the associations of income with both (self-reported) child protective services (CPS) involvement and parenting behaviors that proxy for child abuse and neglect risk among unmarried families. Our primary strategy follows the instrumental variables (IV) approach employed by Dahl and Lochner (2012), which leverages variation between states and over time in the generosity of the total state and federal Earned Income Tax Credit for which a family is eligible to identify exogenous variation in family income. As a robustness check, we also estimate standard OLS regressions (linear probability models), reduced form OLS regressions, and OLS regressions with the inclusion of a control function (each with and without family-specific fixed effects). Our micro-level data are drawn from the Fragile Families and Child Wellbeing Study, a longitudinal birth-cohort of relatively disadvantaged urban children who have been followed from birth to age nine. Results suggest that an exogenous increase in income is associated with reductions in behaviorally-approximated child neglect and CPS involvement, particularly among low-income single-mother families. PMID- 29456464 TI - Three-Dimensional Multiscale, Multistable, and Geometrically Diverse Microstructures with Tunable Vibrational Dynamics Assembled by Compressive Buckling. AB - Microelectromechanical systems remain an area of significant interest in fundamental and applied research due to their wide ranging applications. Most device designs, however, are largely two-dimensional and constrained to only a few simple geometries. Achieving tunable resonant frequencies or broad operational bandwidths requires complex components and/or fabrication processes. The work presented here reports unusual classes of three-dimensional (3D) micromechanical systems in the form of vibratory platforms assembled by controlled compressive buckling. Such 3D structures can be fabricated across a broad range of length scales and from various materials, including soft polymers, monocrystalline silicon, and their composites, resulting in a wide scope of achievable resonant frequencies and mechanical behaviors. Platforms designed with multistable mechanical responses and vibrationally de-coupled constituent elements offer improved bandwidth and frequency tunability. Furthermore, the resonant frequencies can be controlled through deformations of an underlying elastomeric substrate. Systematic experimental and computational studies include structures with diverse geometries, ranging from tables, cages, rings, ring crosses, ring-disks, two-floor ribbons, flowers, umbrellas, triple-cantilever platforms, and asymmetric circular helices, to multilayer constructions. These ideas form the foundations for engineering designs that complement those supported by conventional, microelectromechanical systems, with capabilities that could be useful in systems for biosensing, energy harvesting and others. PMID- 29456465 TI - Barrmaelia and Entosordaria in Barrmaeliaceae (fam. nov., Xylariales) and critical notes on Anthostomella -like genera based on multigene phylogenies. AB - Phylogenetic analyses of a combined DNA data matrix containing ITS, LSU, rpb2 and tub2 sequences of representative Xylariales revealed that the genus Barrmaelia is a well-defined monophylum, as based on four of its described species (B. macrospora, B. moravica, B. oxyacanthae, B. rhamnicola) and the new species B. rappazii. The generic type of Entosordaria, E. perfidiosa, is revealed as the closest relative of Barrmaelia, being phylogenetically distant from the generic type of Clypeosphaeria, C. mamillana, which belongs to Xylariaceae sensu stricto. Entosordaria and Barrmaelia are highly supported and form a distinct lineage, which is recognised as the new family Barrmaeliaceae. The new species E. quercina is described. Barrmaelia macrospora, B. moravica and B. rhamnicola are epitypified and E. perfidiosa is lecto- and epitypified. Published sequences of Anthostomella and several Anthostomella-like species from the genera Alloanthostomella, Anthostomelloides, Neoanthostomella, Pseudoanthostomella and Pyriformiascoma are evaluated, demonstrating the necessity of critical inspection of published sequence data before inclusion in phylogenies. Verified isolates of several species from these genera should be re-sequenced to affirm their phylogenetic affinities. In addition, the generic type of Anthostomella should be sequenced before additional generic re-arrangements are proposed. PMID- 29456466 TI - Mastectomy - Current Challenges and Questions. PMID- 29456467 TI - Clinical Approaches to Breast Reconstruction: What Is the Appropriate Reconstructive Procedure for My Patient? AB - Breast reconstruction after breast cancer is an emotional subject for women. Consequently, the correct timing and surgical procedure for each individual woman are important. In general, heterologous or autologous reconstructive procedures are available, both having advantages and disadvantages. Breast size, patient habitus, and previous surgeries or radiation therapy need to be considered, independent of the chosen procedure. New surgical techniques, refinement of surgical procedures, and the development of supportive materials have increased the general patient collective eligible for breast reconstruction. This review highlights the different approaches to immediate breast reconstruction using autologous or heterologous techniques. PMID- 29456468 TI - Psychosocial Aspects of Immediate versus Delayed Breast Reconstruction. AB - Background: Only little is known about the psychosocial aspects of breast cancer patients after mastectomy with immediate versus delayed breast reconstruction. Methods: We systematically screened PubMed using the following key words: mastectomy, immediate vs. delayed reconstruction, psychosocial aspects and quality of life. To highlight different psychological outcomes, studies were categorized into those describing: anxiety, depression, body image and satisfaction with the surgical outcome. We also compared patients after mastectomy alone with those undergoing immediate or delayed reconstruction. Results: Methodologies and psychological outcomes varied among the identified studies, making it difficult to compare results. There are contradictory outcomes concerning the psychosocial aspects of breast cancer patients after mastectomy alone compared with those who underwent an immediate or delayed reconstruction following mastectomy. Some studies show that immediate reconstruction after mastectomy had a positive impact on patients' psychological well-being. In contrast, other studies indicated that in the long-term view the compared patient groups were very similar concerning psychosocial aspects. Conclusion: Analyzing different aspects of psychosocial well-being after breast cancer surgery, there might be an advantage in choosing immediate reconstruction, if oncological safety allows it. PMID- 29456469 TI - Prophylactic Surgery: For Whom, When and How? AB - Risk-reducing surgery has proved to be a reasonable procedure in healthy women with a definitely elevated risk of developing cancer. Here we consider the elevated risk of breast and ovarian cancer. There is a clear indication for such surgery in healthy women with a pathogenic BRCA1/2 mutation. For these patients, a risk-reducing bilateral mastectomy leads to a verifiable reduction in mortality from breast cancer, particularly for young patients. In most cases, surgery is combined with breast reconstruction. The pros and cons of surgical treatment and the different surgical techniques have to be explained to and carefully considered with the patient. As yet, no unequivocal data for the benefits of intensifying early detection have been ascertained with respect to mortality from breast carcinoma. In index patients with a BRCA mutation, the surgical treatment should depend on the prognosis of the primary disease. A lower age at onset and a better prognosis of the primary disease make a contralateral mastectomy (CPM) more reasonable. In the case of BRCA mutation-related cancer, a reduction of mortality through CPM has been proven. A risk-reducing adnexectomy is basically recommended for BRCA mutation carriers. Healthy premenopausal women need a subsequent hormone replacement therapy. The prognosis of the patients is dominated by the ovarian carcinoma. This can be prevented by risk-reducing salpingo-oophorectomy in 95% of the cases. PMID- 29456470 TI - Is Mastectomy Oncologically Safer than Breast-Conserving Treatment in Early Breast Cancer? AB - Aim: To describe and discuss the evidence for oncological safety of different procedures in oncological breast surgery, i.e. breast-conserving treatment versus mastectomy. Methods: Literature review and discussion. Results: Oncological safety in breast cancer surgery has many dimensions. Breast-conserving treatment has been established as the standard surgical procedure for primary breast cancer and fits to the preferences of most breast cancer patients concerning oncological safety and aesthetic outcome. Conclusions: Breast-conserving treatment is safe. Nonetheless, the preferences of the individual patients in their consideration of breast conservation versus mastectomy should be integrated into routine treatment decisions. PMID- 29456471 TI - Neoadjuvant Chemotherapy Exerts Selection Pressure Towards Luminal Phenotype Breast Cancer. AB - Background: Breast cancer (BC) phenotype after neoadjuvant chemotherapy (NAC) has not been extensively described and few data exist on whether expression of the primary tumor hormone receptors, HER2 and Ki-67 changes as a result of chemotherapy. Materials and Methods: We analyzed specimens from all BC patients treated with anthracycline/taxane-based NAC at our Institution between January 2010 and March 2015 (n = 325). The expression of estrogen receptor (ER), progesterone receptor (PR), HER2 and Ki-67 was determined in pre- and post-NAC specimens. McNemar's test was used to compare paired proportions. Results: Among patients with residual disease after NAC, basal phenotype was luminal A, luminal B, HER2 positive and triple negative in 44, 111, 74 and 27 cases, respectively. PR-positive tumors decreased from 68.0% in the initial biopsy sample to 61.7% in the surgical specimen (p = 0.024). A Ki-67 of < 20% increased from 23.6% to 45% (p < 0.001). ER expression changed from positive to negative in 5% and from negative to positive in 16.7% of cases. Overall, 30% of cases underwent subtype changes, 79% of them towards luminal differentiation. Conclusions: The switch towards luminal phenotype suggests some kind of endocrine effect of NAC. Our findings raise renewed interest in combinatorial cytotoxic chemotherapy with concomitant or rather sequential endocrine therapy, either alone or with targeted agents. PMID- 29456472 TI - Electron Beam Intraoperative Radiotherapy (ELIOT) in Pregnant Women with Breast Cancer: From in Vivo Dosimetry to Clinical Practice. AB - Background: The aim of this study was to confirm our preliminary results with in vivo dosimetry in non-pregnant breast cancer patients receiving electron beam intraoperative radiotherapy (ELIOT) and to report on the first treatment in a pregnant woman. Patients and Methods: Following our previous experience, 5 non pregnant patients receiving ELIOT to the tumor bed after breast-conserving surgery (BCS) were studied with thermoluminescent dosimeters positioned in the subdiaphragmatic region, within the uterus, and in the ovarian region. In December 2011, the first pregnant breast cancer patient underwent BCS and ELIOT (21 Gy at 90% isodose) during the 15th week of gestation. Results: The mean dose to the subdiaphragmatic external region in the 5 non-pregnant patients was 5.57 mGy, while pelvic measurements were below 1 mGy. The actual dosimetry of the pregnant patient showed a mean subdiaphragmatic dose of 4.34 mGy, a mean suprapubic dose of 1.64 mGy, and mean ovarian doses of 1.48 mGy (right-sided) and 1.44 mGy (left-sided). The expected dose to the fetus was estimated as 0.84 mGy (0.004% of the prescribed dose). Conclusion: ELIOT as an anticipated boost to the breast could be considered in pregnant women in the early second trimester, postponing whole-breast irradiation after delivery. PMID- 29456473 TI - Adverse Events of Trastuzumab Emtansine (T-DM1) in the Treatment of HER2-Positive Breast Cancer Patients. AB - The human epidermal growth factor receptor 2 (HER2) is commonly associated with poor prognosis and is overexpressed in approximately 15-20% of all breast cancers. The introduction of HER2-targeted therapies led to significant improvement in the prognosis of patients with HER2-positive breast cancer, for both early and advanced disease. These targeted therapies include the antibodies trastzumab and pertuzumab, the tyrosine kinase inhibitor lapatinib, and the antibody-drug conjugate trastuzumab emtansine (T-DM1). T-DM1 combines the anti tumor activity of trastuzumab with that of DM1, a highly potent derivative of the anti-microtubule agent maytansine, resulting in increased anti-tumor activity. Notably, this agent has been demonstrated to be safe and is associated with low toxicity rates. However, maytansinoid, the cytotoxic component of T-DM1, does have the potential to induce various adverse events, particularly radiation necrosis, when used in combination with stereotactic radiosurgery. In this review, we aimed to summarize the current literature regarding T-DM1 safety and toxicity, with special emphasis on the existing landmark studies. PMID- 29456474 TI - Electrochemotherapy in Breast Cancer - Discussion of the Method and Literature Review. AB - Breast cancer is the most common cause of skin metastases in women. The probability of their occurrence ranges from about 5% in the entire population to as much as 30% in the late stages of the disease. Although rarely life threatening, they have a major impact on the quality of life of patients with this diagnosis, being the cause of pain, effusion, ulceration, infection, and psychological discomfort. Available methods of treatment, both local and systemic, often fail to provide adequate control of the disease. A particular challenge seems to be the treatment of those patients with cutaneous metastases who, due to the extent of their metastases, are not eligible for resection, in whom the possibility of radiation therapy has already been used, and in whom systemic therapy is ineffective or contraindicated. A new method providing the opportunity for effective treatment is electrochemotherapy (ECT). ECT combines electropulsation of tumor cells (by local application of electric pulses) and administration of antineoplastic drugs such as cisplatin or bleomycin (either intravenous or intratumoral). Several clinical studies have demonstrated that ECT provides safe, efficient, and non-invasive locoregional treatment for chest wall breast cancer recurrence.

PMID- 29456477 TI - Dual Diagnosis of Ellis-van Creveld Syndrome and Hearing Loss in a Consanguineous Family. AB - Multilocus analysis of rare or genetically heterogeneous diseases is a distinct advantage of next-generation sequencing (NGS) over conventional single-gene investigations. Recent studies have begun to uncover an under-recognized prevalence of dual molecular diagnoses in patients with a "blended" phenotype that is the result of 2 clinical diagnoses involving 2 separate genetic loci. This blended phenotype could be mistakenly interpreted as a novel clinical extension of a single-gene disorder. In this study, we ascertained a proband from a large consanguineous Iranian family who manifests postlingual, progressive, moderate hearing loss in addition to suspected Ellis-van Creveld syndrome phenotype. NGS with a customized skeletal dysplasia panel containing over 370 genes and subsequent bioinformatics analysis disclosed 2 homozygous mutations in EVC2 (c.2653C>T; p.Arg885*) and COL11A2 (c.966dup; p.Thr323Hisfs*19), respectively. This study highlights a dual molecular diagnosis in a patient with a blending of 2 distinct phenotypes and illustrates the advantage and importance of this staple technology to facilitate rapid and comprehensive genetic dissection of a heterogeneous phenotype. The differentiation between phenotypic expansion of a genetic disorder and a blended phenotype that is due to more than one distinct genetic aberration is essential in order to reduce the diagnostic odyssey endured by patients. PMID- 29456478 TI - Proximal Deletion of 6q Overlapping with Toriello-Carey Facial Phenotype: Prenatal Findings, Clinical Course, Differential Diagnosis, and Review. AB - Proximal deletion of 6q is a relatively rare chromosomal abnormality. Reported patients have deletions of different sizes but share partial overlap and present with similar clinical features, and some of them were described prior to the introduction of chromosome microarrays. We describe a male patient with prenatal sonographic findings of nuchal edema, intrauterine growth restriction, renal pelvis dilatation, and oligohydramnios. At birth, facial dysmorphism, retro/micrognathia, a short and wide neck as well as cardiovascular and renal anomalies were noted. His clinical evolution has been marked by failure to thrive, severe developmental delay, and cognitive impairment. The diagnosis of Toriello-Carey syndrome (TCS) was based on his "gestalt." aCGH identified a de novo proximal deletion of 17 Mb in 6q (6q12q14.3). Deletion 6q13q14 seems to be responsible for the main facial features and should be considered within the differential diagnosis of TCS.

AB - Ectodermal dysplasia-syndactyly syndrome is a rare autosomal recessive congenital disorder caused by mutations in PVRL4 coding for nectin-4. Five different mutations in the PVRL4 gene, including 3 homozygous missense mutations, have been reported. Here, we present an unreported missense variant (c.247C>T, p.His83Tyr) in a consanguineous Turkish family. PMID- 29456480 TI - Novel Homozygous Missense Mutation in RYR1 Leads to Severe Congenital Ptosis, Ophthalmoplegia, and Scoliosis in the Absence of Myopathy. AB - Ryanodine receptor 1 (RYR1) is an intracellular calcium receptor primarily expressed in skeletal muscle with a role in excitation contraction. Both dominant and recessive mutations in the RYR1 gene cause a range of RYR1-related myopathies and/or susceptibility to malignant hyperthermia (MH). Recently, an atypical manifestation of ptosis, variably presenting with ophthalmoplegia, facial paralysis, and scoliosis but without significant muscle weakness, has been reported in 9 cases from 4 families with bialleic variants in RYR1. Two affected children from a consanguineous family with severe congenital ptosis, ophthalmoplegia, scoliosis, and distinctive long faces but without skeletal myopathy were studied. To identify the cause of the hereditary condition, DNA from the proband was subjected to whole exome sequencing (WES). WES revealed a novel homozygous missense variant in RYR1 (c.14066T>A; p.IIe4689Asn), which segregated within the family. Although the phenotype of the affected siblings in this study was similar to previously described cases, the clinical features were more severely expressed. Our findings contribute to the expansion of phenotypes related to RYR1 dysfunction. Additionally, it supports a new RYR1-related clinical presentation without musculoskeletal involvement. It is important that individuals with RYR1 mutations are considered susceptible to MH, as 70% of the MH cases are caused by mutations in the RYR1 gene. PMID- 29456481 TI - Double Interstitial Deletion of the Long Arm of Chromosome 6 in a Patient with Pierre Robin Sequence, Dysmorphisms, and Severe Developmental Delay. AB - Reported here is the case of a 1.8-year-old boy with a 9.6- Mb deletion in 6q13q14.1 and an 11.2-Mb deletion in 6q21q22.31, ascertained through array CGH, as the result of a complex de novo chromosome rearrangement. The clinical picture of this patient is characterized by severe psychomotor delay, dysmorphic features, and some congenital defects. Although, as reported in the literature, phenotypes associated with 6q deletions may vary, an attempt was made to associate the patient's symptoms to either deletion, comparing them to previously reported cases. Only a limited specific correlation was found, probably due to the prevalence of very common symptoms. PMID- 29456482 TI - Ring Chromosome 17 Not Involving the Miller-Dieker Region: A Case with Drug Resistant Epilepsy. AB - Chromosomal abnormalities are often identified in people with neurodevelopmental disorders including intellectual disability, autism, and epilepsy. Ring chromosomes, which usually involve gene copy number loss, are formed by fusion of subtelomeric or telomeric chromosomal regions. Some ring chromosomes, including ring 14, 17, and 20, are strongly associated with seizure disorders. We report an individual with a ring chromosome 17, r(17)(p13.3q25.3), with a terminal 17q25.3 deletion and no short arm copy number loss, and with a phenotype characterized by intellectual disability and drug-resistant epilepsy, including a propensity for nonconvulsive status epilepticus. PMID- 29456483 TI - Two Novel Pathogenic MID1 Variants and Genotype-Phenotype Correlation Reanalysis in X-Linked Opitz G/BBB Syndrome. AB - X-linked Opitz G/BBB syndrome (XLOS) is a multisystemic congenital condition, caused by mutations in the midline-1 gene (MID1), characterized by a large inter- and intrafamilial phenotypic variability and often associated with intellectual disability (ID). We report clinical, genetic, and molecular findings in 4 patients with typical XLOS dysmorphic features belonging to 2 unrelated families. Two novel pathogenic loss-of-function MID1 variants, a maternally inherited c.1656del and a de novo c.1215_1228dup, were identified. Subsequently, we performed a genotype-phenotype analysis using data from 91 male XLOS patients. To test the mutation impact on the phenotype; the type of mutation, the MID1 impaired domain and function were compared with the presence of each of the major clinical features (hypertelorism, clefts of the lip and/or palate, laryngo tracheo-esophageal abnormalities, hypospadias and ID) and minor clinical features (brain, heart, and anal defects). No statistically significant correlation was found with these features. Further investigations, as well as exhaustive and unequivocal phenotyping, may be required to improve our knowledge of the biological mechanisms underlying this syndrome and to provide more adequate disease management. PMID- 29456484 TI - 7q Deletion/12q Duplication Is the Possible Cause of an Alobar Holoprosencephaly Case. AB - Holoprosencephaly (HPE) spectrum disorder is the most common congenital malformation of the human brain with absence of or incomplete midline cleavage. Its cause is heterogenic, making genetic counseling a challenge. In this case report, a pregnancy affected by alobar HPE is described. Using aCGH, an 8.9-Mb deletion at 7q36.1q36.3 together with a 4.9-Mb duplication at 12q24.32q24.33 is assumed to be the possible reason for this alobar HPE case. It is discussed that disruption of key elements of the developing brain, taking environmental factors into account, contributes to the HPE spectrum. The use of aCGH for invasive prenatal testing is starting to become the standard technique, providing accurate information about the cause of congenital diseases for couples receiving genetic counseling. PMID- 29456485 TI - Effect of Spatial Smoothing on Task fMRI ICA and Functional Connectivity. AB - Spatial smoothing is a widely used preprocessing step in functional magnetic resonance imaging (fMRI) data analysis. In this work, we report on the spatial smoothing effect on task-evoked fMRI brain functional mapping and functional connectivity. Initially, we decomposed the task fMRI data into a collection of components or networks by independent component analysis (ICA). The designed task paradigm helps identify task-modulated ICA components (highly correlated with the task stimuli). For the ICA-extracted primary task component, we then measured the task activation volume at the task response foci. We used the task timecourse (designed) as a reference to order the ICA components according to the task correlations of the ICA timecourses. With the re-ordered ICA components, we calculated the inter-component function connectivity (FC) matrix (correlations among the ICA timecourses). By repeating the spatial smoothing of fMRI data with a Gaussian smoothing kernel with a full width at half maximum (FWHM) of {1, 3, 6, 9, 12, 15, 20, 25, 30, 35} mm, we measured the spatial smoothing effects. Our results show spatial smoothing reveals the following effects: (1) It decreases the task extraction performance of single-subject ICA more than that of multi subject ICA; (2) It increases the task volume of multi-subject ICA more than that of single-subject ICA; (3) It strengthens the functional connectivity of single subject ICA more than that of multi-subject ICA; and (4) It impacts the positive negative imbalance of single-subject ICA more than that of multi-subject ICA. Our experimental results suggest a 2~3 voxel FWHM spatial smoothing for single subject ICA in achieving an optimal balance of functional connectivity, and a wide range (2~5 voxels) of FWHM for multi-subject ICA. PMID- 29456486 TI - Generic HRTFs May be Good Enough in Virtual Reality. Improving Source Localization through Cross-Modal Plasticity. AB - Auditory spatial localization in humans is performed using a combination of interaural time differences, interaural level differences, as well as spectral cues provided by the geometry of the ear. To render spatialized sounds within a virtual reality (VR) headset, either individualized or generic Head Related Transfer Functions (HRTFs) are usually employed. The former require arduous calibrations, but enable accurate auditory source localization, which may lead to a heightened sense of presence within VR. The latter obviate the need for individualized calibrations, but result in less accurate auditory source localization. Previous research on auditory source localization in the real world suggests that our representation of acoustic space is highly plastic. In light of these findings, we investigated whether auditory source localization could be improved for users of generic HRTFs via cross-modal learning. The results show that pairing a dynamic auditory stimulus, with a spatio-temporally aligned visual counterpart, enabled users of generic HRTFs to improve subsequent auditory source localization. Exposure to the auditory stimulus alone or to asynchronous audiovisual stimuli did not improve auditory source localization. These findings have important implications for human perception as well as the development of VR systems as they indicate that generic HRTFs may be enough to enable good auditory source localization in VR. PMID- 29456487 TI - The Discontinuous Galerkin Finite Element Method for Solving the MEG and the Combined MEG/EEG Forward Problem. AB - In Electro- (EEG) and Magnetoencephalography (MEG), one important requirement of source reconstruction is the forward model. The continuous Galerkin finite element method (CG-FEM) has become one of the dominant approaches for solving the forward problem over the last decades. Recently, a discontinuous Galerkin FEM (DG FEM) EEG forward approach has been proposed as an alternative to CG-FEM (Engwer et al., 2017). It was shown that DG-FEM preserves the property of conservation of charge and that it can, in certain situations such as the so-called skull leakages, be superior to the standard CG-FEM approach. In this paper, we developed, implemented, and evaluated two DG-FEM approaches for the MEG forward problem, namely a conservative and a non-conservative one. The subtraction approach was used as source model. The validation and evaluation work was done in statistical investigations in multi-layer homogeneous sphere models, where an analytic solution exists, and in a six-compartment realistically shaped head volume conductor model. In agreement with the theory, the conservative DG-FEM approach was found to be superior to the non-conservative DG-FEM implementation. This approach also showed convergence with increasing resolution of the hexahedral meshes. While in the EEG case, in presence of skull leakages, DG-FEM outperformed CG-FEM, in MEG, DG-FEM achieved similar numerical errors as the CG FEM approach, i.e., skull leakages do not play a role for the MEG modality. In particular, for the finest mesh resolution of 1 mm sources with a distance of 1.59 mm from the brain-CSF surface, DG-FEM yielded mean topographical errors (relative difference measure, RDM%) of 1.5% and mean magnitude errors (MAG%) of 0.1% for the magnetic field. However, if the goal is a combined source analysis of EEG and MEG data, then it is highly desirable to employ the same forward model for both EEG and MEG data. Based on these results, we conclude that the newly presented conservative DG-FEM can at least complement and in some scenarios even outperform the established CG-FEM approaches in EEG or combined MEG/EEG source analysis scenarios, which motivates a further evaluation of DG-FEM for applications in bioelectromagnetism. PMID- 29456488 TI - Exploring the Complexity of Cortical Development Using Single-Cell Transcriptomics. AB - The developing neocortex in the mammalian brain is composed of multiple cell types including apical progenitors (AP), basal progenitors (BP), and neurons that populate three different layers, the ventricular zone (VZ), the subventricular zone (SVZ), and the cortical plate (CP). Despite recent advances, the diversity of the existing cell populations including those which are differentiating and mature, their biogenesis and the underlying gene regulatory mechanisms remain poorly known. Recent studies have taken advantage of the rapidly emerging single cell technologies to decode the heterogeneity of cell populations at the transcriptome level during cortical development and their molecular details. Here we review these studies and provide an overview of the steps in single-cell transcriptomics including both experimental and computational analysis. We also discuss how single-cell genomics holds a big potential in future for brain research and discuss its possible applications and biological insights that can be achieved from these approaches. We conclude this review by discussing the current challenges in the implementation of single-cell techniques toward a comprehensive understanding of the genetic and epigenetic mechanisms underlying neocortex development. PMID- 29456489 TI - Hurst Exponent Analysis of Resting-State fMRI Signal Complexity across the Adult Lifespan. AB - Exploring functional information among various brain regions across time enables understanding of healthy aging process and holds great promise for age-related brain disease diagnosis. This paper proposed a method to explore fractal complexity of the resting-state functional magnetic resonance imaging (rs-fMRI) signal in the human brain across the adult lifespan using Hurst exponent (HE). We took advantage of the examined rs-fMRI data from 116 adults 19 to 85 years of age (44.3 +/- 19.4 years, 49 females) from NKI/Rockland sample. Region-wise and voxel wise analyses were performed to investigate the effects of age, gender, and their interaction on complexity. In region-wise analysis, we found that the healthy aging is accompanied by a loss of complexity in frontal and parietal lobe and increased complexity in insula, limbic, and temporal lobe. Meanwhile, differences in HE between genders were found to be significant in parietal lobe (p = 0.04, corrected). However, there was no interaction between gender and age. In voxel wise analysis, the significant complexity decrease with aging was found in frontal and parietal lobe, and complexity increase was found in insula, limbic lobe, occipital lobe, and temporal lobe with aging. Meanwhile, differences in HE between genders were found to be significant in frontal, parietal, and limbic lobe. Furthermore, we found age and sex interaction in right parahippocampal gyrus (p = 0.04, corrected). Our findings reveal HE variations of the rs-fMRI signal across the human adult lifespan and show that HE may serve as a new parameter to assess healthy aging process. PMID- 29456491 TI - Synaptic E-I Balance Underlies Efficient Neural Coding. AB - Both theoretical and experimental evidence indicate that synaptic excitation and inhibition in the cerebral cortex are well-balanced during the resting state and sensory processing. Here, we briefly summarize the evidence for how neural circuits are adjusted to achieve this balance. Then, we discuss how such excitatory and inhibitory balance shapes stimulus representation and information propagation, two basic functions of neural coding. We also point out the benefit of adopting such a balance during neural coding. We conclude that excitatory and inhibitory balance may be a fundamental mechanism underlying efficient coding. PMID- 29456490 TI - Limited Access to a High Fat Diet Alters Endocannabinoid Tone in Female Rats. AB - Emerging evidence suggest an impaired endocannabinoid activity in the pathophysiology of binge eating disorder (BED). Herein, we investigated whether endocannabinoid tone could be modified as a consequence of dietary-induced binge eating in female rats. For this purpose, brain levels of the endocannabinoids anandamide (AEA) and 2-arachidonoyl glycerol (2-AG), as well as two endocannabinoid-like lipids, oleoylethanolamide (OEA) and palmitoylethanolamide (PEA), were assessed in different brain areas involved in the hedonic feeding (i.e., prefrontal cortex, nucleus accumbens, amygdala, hippocampus, and hypothalamus). The brain density of cannabinoid type-1 receptors (CB1) was also evaluated. Furthermore, we determined plasma levels of leptin, ghrelin, and corticosterone hormones, which are well-known to control the levels of endocannabioids and/or CB1 receptors in the brain. To induce binge eating behavior, rats were subject to an intermittent and limited access to a high fat diet (HFD) (margarine). Three experimental groups were used, all with ad libitum access to chow: control (CTRL), with no access to margarine; low restriction (LR), with 2 h margarine access 7 days/week; high restriction (HR), with 2 h margarine access 3 days/week. Bingeing was established when margarine intake in the HR group exceeded that of the LR group. Our results show that, compared to CTRL, AEA significantly decreased in the caudate putamen, amygdala, and hippocampus of HR group. In contrast, 2-AG significantly increased in the hippocampus while OEA decreased in the hypothalamus. Similar to the HR group, AEA and OEA decreased respectively in the amygdala and hypothalamus and 2-AG increased in the hippocampus of LR group. Moreover, LR group also had AEA decreased in the prefrontal cortex and increased in the nucleus accumbens. In both groups we found the same reduction of CB1 receptor density in the prefrontal cortex compared to CTRL. Also, LR and HR groups showed alterations in both ghrelin and corticosterone levels, while leptin remained unaltered. In conclusion, our findings show a modified endocannabinoid tone due to margarine exposure, in several brain areas that are known to influence the hedonic aspect of food. Even if not uniquely specific to binge eating, margarine-induced changes in endocannabinoid tone could contributes to the development and maintenance of this behavior. PMID- 29456492 TI - Novel pH-Sensitive Lipid Based Exo-Endocytosis Tracers Reveal Fast Intermixing of Synaptic Vesicle Pools. AB - Styryl dyes and genetically encoded pH-sensitive fluorescent proteins like pHluorin are well-established tools for the optical analysis of synaptic vesicle (SV) recycling at presynaptic boutons. Here, we describe the development of a new class of fluorescent probes based on pH-sensitive organic dyes covalently bound to lipids, providing a promising complementary assay to genetically encoded fluorescent probes. These new optical tracers allow a pure read out of membrane turnover during synaptic activity and visualization of multiple rounds of stimulation-dependent SV recycling without genetic perturbation. Measuring the incorporation efficacy of different dye-labeled lipids into budding SVs, we did not observe an enrichment of lipids with affinity for liquid ordered membrane domains. But most importantly, we found no evidence for a static segregation of SVs into recycling and resting pools. A small but significant fraction of SVs that is reluctant to release during a first round of evoked activity can be exocytosed during a second bout of stimulation, showing fast intermixing of SV pools within seconds. Furthermore, we found that SVs recycling spontaneously have a higher chance to re-occupy release sites than SVs recycling during high frequency evoked activity. In summary, our data provide strong evidence for a highly dynamic and use-dependent control of the fractions of releasable or resting SVs. PMID- 29456493 TI - Administration of Ketamine Causes Autophagy and Apoptosis in the Rat Fetal Hippocampus and in PC12 Cells. AB - Drug abuse during pregnancy is a serious problem. Like alcohol, anticonvulsants, sedatives, and anesthetics, such as ketamine, can pass through the placental barrier and affect the growing fetus. However, the mechanism by which ketamine causes damage to fetal rats is not well understood. Therefore, in this study, we anesthetized pregnant rats with ketamine and evaluated the Total Antioxidant Capacity (T-AOC), Reactive Oxygen Species (ROS), and Malondialdehyde (MDA). Moreover, we determined changes in the levels of Cleaved-Caspase-3 (C-Caspase-3), Beclin-1, B-cell lymphoma-2 (Bcl-2), Bcl-2 Associated X Protein (Bax), Autophagy related gene 4 (Atg4), Atg5, p62 (SQSTM1), and marker of autophagy Light Chain 3 (LC3). In addition, we cultured PC12 cells in vitro to determine the relationship between ROS, autophagy, and apoptosis following ketamine treatment. The results showed that ketamine induced changes in autophagy- and apoptosis-related proteins, reduced T-AOC, and generated excessive levels of ROS and MDA. In vitro experiments showed similar results, indicating that apoptosis levels can be inhibited by 3-MA. We also found that autophagy and apoptosis can be inhibited by N-acetyl-L-cysteine (Nac). Thus, anesthesia with ketamine in pregnant rats may increase the rate of autophagy and apoptosis in the fetal hippocampus and the mechanism may be through inhibition of antioxidant activity and ROS accumulation. PMID- 29456494 TI - The Influence of Feedback on Task-Switching Performance: A Drift Diffusion Modeling Account. AB - Task-switching is an important cognitive skill that facilitates our ability to choose appropriate behavior in a varied and changing environment. Task-switching training studies have sought to improve this ability by practicing switching between multiple tasks. However, an efficacious training paradigm has been difficult to develop in part due to findings that small differences in task parameters influence switching behavior in a non-trivial manner. Here, for the first time we employ the Drift Diffusion Model (DDM) to understand the influence of feedback on task-switching and investigate how drift diffusion parameters change over the course of task switch training. We trained 316 participants on a simple task where they alternated sorting stimuli by color or by shape. Feedback differed in six different ways between subjects groups, ranging from No Feedback (NFB) to a variety of manipulations addressing trial-wise vs. Block Feedback (BFB), rewards vs. punishments, payment bonuses and different payouts depending upon the trial type (switch/non-switch). While overall performance was found to be affected by feedback, no effect of feedback was found on task-switching learning. Drift Diffusion Modeling revealed that the reductions in reaction time (RT) switch cost over the course of training were driven by a continually decreasing decision boundary. Furthermore, feedback effects on RT switch cost were also driven by differences in decision boundary, but not in drift rate. These results reveal that participants systematically modified their task switching performance without yielding an overall gain in performance. PMID- 29456495 TI - Structural Variation of Chondroitin Sulfate Chains Contributes to the Molecular Heterogeneity of Perineuronal Nets. AB - Aggrecan, a chondroitin sulfate (CS) proteoglycan, forms lattice-like extracellular matrix structures called perineuronal nets (PNNs). Neocortical PNNs primarily ensheath parvalbumin-expressing inhibitory neurons (parvalbumin, PV cells) late in brain development. Emerging evidence indicates that PNNs promote the maturation of PV cells by enhancing the incorporation of homeobox protein Otx2 and regulating experience-dependent neural plasticity. Wisteria floribunda agglutinin (WFA), an N-acetylgalactosamine-specific plant lectin, binds to the CS chains of aggrecan and has been widely used to visualize PNNs. Although PNNs show substantial molecular heterogeneity, the importance of this heterogeneity in neural plasticity remains unknown. Here, in addition to WFA lectin, we used the two monoclonal antibodies Cat315 and Cat316, both of which recognize the glycan structures of aggrecan, to investigate the molecular heterogeneity of PNNs. WFA detected the highest number of PNNs in all cortical layers, whereas Cat315 and Cat316 labeled only a subset of PNNs. WFA+, Cat315+, and Cat316+ PNNs showed different laminar distributions in the adult visual cortex. WFA, Cat315 and Cat316 detected distinct, but partially overlapping, populations of PNNs. Based on the reactivities of these probes, we categorized PNNs into four groups. We found that two subpopulation of PNNs, one with higher and one with lower WFA staining are differentially labeled by Cat316 and Cat315, respectively. CS chains recognized by Cat316 were diminished in mice deficient in an enzyme involved in the initiation of CS-biosynthesis. Furthermore, WFA+ and Cat316+ aggrecan were spatially segregated and formed microdomains in a single PNN. Otx2 co-localized with Cat316+ but not with WFA+ aggrecan in PNNs. Our results suggest that the heterogeneity of PNNs around PV cells may affect the functional maturation of these cells. PMID- 29456496 TI - How Do Acquired Political Identities Influence Our Neural Processing toward Others within the Context of a Trust Game? AB - Trust is essential for mutually beneficial human interactions in economic exchange and politics and people's social identities notably have dramatic effects on trust behaviors toward others. Previous literature concerning social identities generally suggests that people tend to show in-group favoritism toward members who share the same identity. However, how our brains process signals of identity while facing uncertain situations in interpersonal interactions remains largely unclear. To address this issue, we performed an fMRI experiment with 54 healthy adults who belonged to two identity groups of opposing political orientations. The identity information of participants was extracted from a large scale social survey on the 2012 Taiwan presidential election. Accordingly, participants were categorized as either the Kuomintang (KMT) or the Democratic Progressive Party (DPP) supporters. During the experiment, participants played trust games with computer agents with labels of the same or the opposing political identity. Interestingly, our results suggest that the behaviors of the two groups cannot be equally attributed to in-group favoritism. Behaviorally, only the DPP supporter group showed a significant trust preference toward in group members, which did not hold for the KMT supporter group. Consistently, neurophysiological findings further revealed that only the DPP supporter group showed neuronal responses to both unexpected negative feedback from in-group members in anterior insula, temporoparietal junction, and dorsal lateral prefrontal cortex, as well as to unexpected rewards from out-group members in caudate. These findings therefore suggest that acquired identities play a more complex role in modulating people's social expectation in interpersonal trust behaviors under identity-relevant contexts.

AB - Discrimination of two neighboring empty durations that are marked by three successive sounds is improved when the presentation of the first (standard, S) duration is repeated before that of the second (comparison, C), as SSSSC. This improvement in sensitivity, called the multiple-look effect, has been explained by a statistical model regarding variability. This model assumes that the perceived duration of the standard is averaged across observations (within a trial within an individual). The increasing of the number of observations thus reduces the standard error of the mean perceived duration. Alternatively, the multiple-look effect is attributed to the listener's prediction based on regular rhythm. Listeners perceive regular rhythm during the repetition of the standard, predict the timing of subsequent sounds, and detect a sound that is displaced from the predicted timing. These models were tested in the present experiment in which the main factor was a temporal separation between the standard and the comparison; i.e., these durations were adjacent to each other as SSSSC or separated by a temporal blank as SSSS_C. The results differed between stimulus structures. First, the multiple-look effect was replicated in the SSSSC condition (yielding a higher performance than SC), but disappeared in SSSS_C (having no difference with S_C). Second, no multiple-look effect occurred in CSSSS (no difference with CS), and moreover, an impairment effect was observed in C_SSSS (a lower performance than C_S). Finally, discrimination was improved in SSSS_CCCC compared with SSSSCCCC, the effect being kept even when sounds were aligned at irregular intervals. These findings are not consistent with those expected from the statistical model because the temporal separation should have produced no effects if the number of standards had been a sole parameter determining the multiple-look effect. The prediction-based model can explain the first finding; inserting a blank between the standard and the comparison violates the listener's prediction based on regular rhythm, thus reducing the multiple-look effect. However, it did not expect the other findings and required revisions. Notably, the second finding indicates that the formation of regular rhythm can impair temporal discrimination. In other words, an inversed multiple-look effect occurs. PMID- 29456498 TI - Using SPM 12's Second-Level Bayesian Inference Procedure for fMRI Analysis: Practical Guidelines for End Users. AB - Recent debates about the conventional traditional threshold used in the fields of neuroscience and psychology, namely P < 0.05, have spurred researchers to consider alternative ways to analyze fMRI data. A group of methodologists and statisticians have considered Bayesian inference as a candidate methodology. However, few previous studies have attempted to provide end users of fMRI analysis tools, such as SPM 12, with practical guidelines about how to conduct Bayesian inference. In the present study, we aim to demonstrate how to utilize Bayesian inference, Bayesian second-level inference in particular, implemented in SPM 12 by analyzing fMRI data available to public via NeuroVault. In addition, to help end users understand how Bayesian inference actually works in SPM 12, we examine outcomes from Bayesian second-level inference implemented in SPM 12 by comparing them with those from classical second-level inference. Finally, we provide practical guidelines about how to set the parameters for Bayesian inference and how to interpret the results, such as Bayes factors, from the inference. We also discuss the practical and philosophical benefits of Bayesian inference and directions for future research. PMID- 29456499 TI - Can We Achieve Intuitive Prosthetic Elbow Control Based on Healthy Upper Limb Motor Strategies? AB - Most transhumeral amputees report that their prosthetic device lacks functionality, citing the control strategy as a major limitation. Indeed, they are required to control several degrees of freedom with muscle groups primarily used for elbow actuation. As a result, most of them choose to have a one-degree of-freedom myoelectric hand for grasping objects, a myoelectric wrist for pronation/supination, and a body-powered elbow. Unlike healthy upper limb movements, the prosthetic elbow joint angle, adjusted prior to the motion, is not involved in the overall upper limb movements, causing the rest of the body to compensate for the lack of mobility of the prosthesis. A promising solution to improve upper limb prosthesis control exploits the residual limb mobility: like in healthy movements, shoulder and prosthetic elbow motions are coupled using inter-joint coordination models. The present study aims to test this approach. A transhumeral amputated individual used a prosthesis with a residual limb motion driven elbow to point at targets. The prosthetic elbow motion was derived from IMU-based shoulder measurements and a generic model of inter-joint coordinations built from healthy individuals data. For comparison, the participant also performed the task while the prosthetic elbow was implemented with his own myoelectric control strategy. The results show that although the transhumeral amputated participant achieved the pointing task with a better precision when the elbow was myoelectrically-controlled, he had to develop large compensatory trunk movements. Automatic elbow control reduced trunk displacements, and enabled a more natural body behavior with synchronous shoulder and elbow motions. However, due to socket impairments, the residual limb amplitudes were not as large as those of healthy shoulder movements. Therefore, this work also investigates if a control strategy whereby prosthetic joints are automatized according to healthy individuals' coordination models can lead to an intuitive and natural prosthetic control. PMID- 29456501 TI - Recommendations for the Design of Serious Games in Neurodegenerative Diseases. AB - The use of Serious Games (SG) in the health domain is expanding. In the field of Neurodegenerative Diseases (ND) such as Alzheimer's Disease, SG are currently employed to provide alternative solutions for patients' treatment, stimulation, and rehabilitation. The design of SG for people with ND implies collaborations between professionals in ND and professionals in SG design. As the field is quite young, professionals specialized in both ND and SG are still rare, and recommendations for the design of SG for people with ND are still missing. This perspective paper aims to provide recommendations in terms of ergonomic choices for the design of SG aiming at stimulating people with ND, starting from the existing SG already tested in this population: "MINWii", "Kitchen and Cooking", and "X-Torp". We propose to rely on nine ergonomic criteria: eight ergonomic criteria inspired by works in the domain of office automation: Compatibility, Guidance, Workload, Adaptability, Consistency, Significance of codes, Explicit control and Error management; and one ergonomic criterion related to videogame: the game rules. Perspectives derived from this proposal are also discussed. PMID- 29456500 TI - Auditory Memory Decay as Reflected by a New Mismatch Negativity Score Is Associated with Episodic Memory in Older Adults at Risk of Dementia. AB - The auditory mismatch negativity (MMN) is an event-related potential (ERP) peaking about 100-250 ms after the onset of a deviant tone in a sequence of identical (standard) tones. Depending on the interstimulus interval (ISI) between standard and deviant tones, the MMN is suitable to investigate the pre-attentive auditory discrimination ability (short ISIs, <= 2 s) as well as the pre-attentive auditory memory trace (long ISIs, >2 s). However, current results regarding the MMN as an index for mild cognitive impairment (MCI) and dementia are mixed, especially after short ISIs: while the majority of studies report positive associations between the MMN and cognition, others fail to find such relationships. To elucidate these so far inconsistent results, we investigated the validity of the MMN as an index for cognitive impairment exploring the associations between different MMN indices and cognitive performance, more specifically with episodic memory performance which is among the most affected cognitive domains in the course of Alzheimer's dementia (AD), at baseline and at a 5-year-follow-up. We assessed the amplitude of the MMN for short ISI (stimulus onset asynchrony, SOA = 0.05 s) and for long ISI (3 s) in a neuropsychologically well-characterized cohort of older adults at risk of dementia (subjective memory impairment, amnestic and non-amnestic MCI; n = 57). Furthermore, we created a novel difference score (DeltaMMN), defined as the difference between MMNs to short and to long ISI, as a measure to assess the decay of the auditory memory trace, higher values indicating less decay. DeltaMMN and MMN amplitude after long ISI, but not the MMN amplitude after short ISI, was associated with episodic memory at baseline (beta = 0.38, p = 0.003; beta = -0.27, p = 0.047, respectively). DeltaMMN, but not the MMN for long ISIs, was positively associated with episodic memory performance at the 5-year-follow-up (beta = 0.57, p = 0.013). The results suggest that the MMN after long ISI might be suitable as an indicator for the decline in episodic memory and indicate DeltaMMN as a potential biomarker for memory impairment in older adults at risk of dementia. PMID- 29456502 TI - Efficacy of Cognitive Training in Older Adults with and without Subjective Cognitive Decline Is Associated with Inhibition Efficiency and Working Memory Span, Not with Cognitive Reserve. AB - The present study explores the role of cognitive reserve, executive functions, and working memory (WM) span, as factors that might explain training outcomes in cognitive status. Eighty-one older adults voluntarily participated in the study, classified either as older adults with subjective cognitive decline or cognitively intact. Each participant underwent a neuropsychological assessment that was conducted both at baseline (entailing cognitive reserve, executive functions, WM span and depressive symptomatology measures, as well as the Mini Mental State Exam regarding initial cognitive status), and then 6 months later, once each participant had completed the training program (Mini-Mental State Exam at the endpoint). With respect to cognitive status the training program was most beneficial for subjective cognitive decline participants with low efficiency in inhibition at baseline (explaining a 33% of Mini-Mental State Exam total variance), whereas for cognitively intact participants training gains were observed for those who presented lower WM span. PMID- 29456503 TI - SMO Inhibition Modulates Cellular Plasticity and Invasiveness in Colorectal Cancer. AB - HIGHLIGHTS Preliminary results of this work were presented at the 2016 Academic Surgical Congress, Jacksonville (FL), February 2-4 2016 (Original title: Selective Smo-Inhibition Interferes With Cellular Energetic Metabolism In Colorectal Cancer)This study was funded by "Sapienza-University of Rome" (Funds for young researchers) and "AIRC" (Italian Association for Cancer Research)Hedgehog inhibitor was kindly provided by Genentech, Inc.(r). Colon Cancer (CC) is the fourth most frequently diagnosed tumor and the second leading cause of death in the USA. Abnormalities of Hedgehog pathway have been demonstrated in several types of human cancers, however the role of Hedgehog (Hh) in CC remain controversial. In this study, we analyzed the association between increased mRNA expression of GLI1 and GLI2, two Hh target genes, and CC survival and recurrence by gene expression microarray from a cohort of 382 CC patients. We found that patients with increased expression of GLI1 showed a statistically significant reduction in survival. In order to demonstrate a causal role of Hh pathway activation in the pathogenesis of CC, we treated HCT 116, SW480 and SW620 CC cells lines with GDC-0449, a pharmacological inhibitor of Smoothened (SMO). Treatment with GDC-0449 markedly reduced expression of Hh target genes GLI1, PTCH1, HIP1, MUC5AC, thus indicating that this pathway is constitutively active in CC cell lines. Moreover, GDC-0449 partially reduced cell proliferation, which was associated with upregulation of p21 and downregulation of CycD1. Finally, treatment with the same drug reduced migration and three-dimensional invasion, which were associated with downregulation of Snail1, the EMT master gene, and with induction of the epithelial markers Cytokeratin-18 and E-cadherin. These results were confirmed by SMO genetic silencing. Notably, treatment with 5E1, a Sonic Hedgehog-specific mAb, markedly reduced the expression of Hedgehog target genes, as well as inhibited cell proliferation and mediated reversion toward an epithelial phenotype. This suggests the existence of a Hedgehog autocrine signaling loop affecting cell plasticity and fostering cell proliferation and migration/invasion in CC cell lines. These discoveries encourage future investigations to better characterize the role of Hedgehog in cellular plasticity and invasion during the different steps of CC pathogenesis. PMID- 29456504 TI - A Review on Central Nervous System Effects of Gastrodin. AB - Rhizoma Gastrodiae (also known as Tian ma), the dried rhizome of Gastrodia elata Blume, is a famous Chinese herb that has been traditionally used for the treatment of headache, dizziness, spasm, epilepsy, stoke, amnesia and other disorders for centuries. Gastrodin, a phenolic glycoside, is the main bioactive constituent of Rhizoma Gastrodiae. Since identified in 1978, gastrodin has been extensively investigated on its pharmacological properties. In this article, we reviewed the central nervous system (CNS) effects of gastrodin in preclinical models of CNS disorders including epilepsy, Alzheimer's disease, Parkinson's disease, affective disorders, cerebral ischemia/reperfusion, cognitive impairment as well as the underlying mechanisms involved and, where possible, clinical data that support the pharmacological activities. The sources and pharmacokinetics of gastrodin were also reviewed here. As a result, gastrodin possesses a broad range of beneficial effects on the above-mentioned CNS diseases, and the mechanisms of actions include modulating neurotransmitters, antioxidative, anti-inflammatory, suppressing microglial activation, regulating mitochondrial cascades, up regulating neurotrophins, etc. However, more detailed clinical trials are still in need for positioning it in the treatment of neurological disorders. PMID- 29456506 TI - Therapeutic Effects of a Traditional Chinese Medicine Formula Plus Tamoxifen vs. Tamoxifen for the Treatment of Mammary Gland Hyperplasia: A Meta-Analysis of Randomized Trials. AB - As a common disorder that accounts for over 70% of all breast disease cases, mammary gland hyperplasia (MGH) causes a severe problem for the quality of patients' life, and confers an increased risk of breast carcinoma. However, the etiology and pathogenesis of MGH remain unclear, and the safety and efficacy of current western drug therapy for MGH still need to be improved. Therefore, a meta analysis was conducted by our team to determine whether a TCM formula named Ru-Pi Xiao in combination with tamoxifen or Ru-Pi-Xiao treated alone can show more prominent therapeutic effects against MGH with fewer adverse reactions than that of tamoxifen. Studies published before June 2017 were searched based on standardized searching rules in several mainstream medical databases. A total of 27 articles with 4,368 patients were enrolled in this meta-analysis. The results showed that the combination of Ru-Pi-Xiao and tamoxifen could exhibit better therapeutic effects against MGH than that of tamoxifen (OR: 3.79; 95% CI: 3.09 4.65; P < 0.00001) with a lower incidence of adverse reactions (OR: 0.35; 95% CI: 0.28-0.43; P < 0.00001). The results also suggested that this combination could improve the level of progesterone (MD: 2.22; 95% CI: 1.72-2.71; P < 0.00001) and decrease the size of breast lump (MD: -0.67; 95% CI: -0.86 to -0.49; P < 0.00001) to a greater extent, which might provide a possible explanation for the pharmacodynamic mechanism of Ru-Pi-Xiao plus tamoxifen. In conclusion, Ru-Pi-Xiao and related preparations could be recommended as auxiliary therapy combined tamoxifen for the treatment of MGH. PMID- 29456505 TI - Deletion of Trace Amine-Associated Receptor 1 Attenuates Behavioral Responses to Caffeine. AB - Trace amines (TAs), endogenous amino acid metabolites that are structurally similar to the biogenic amines, are endogenous ligands for trace amine-associated receptor 1 (TAAR1), a GPCR that modulates dopaminergic, serotonergic, and glutamatergic activity. Selective TAAR1 full and partial agonists exhibit similar pro-cognitive, antidepressant- and antipsychotic-like properties in rodents and non-human primates, suggesting TAAR1 as a novel target for the treatment of neurological and psychiatric disorders. We previously reported that TAAR1 partial agonists are wake-promoting in rats and mice, and that TAAR1 knockout (KO) and overexpressing mice exhibit altered sleep-wake and EEG spectral composition. Here, we report that locomotor and EEG spectral responses to the psychostimulants modafinil and caffeine are attenuated in TAAR1 KO mice. TAAR1 KO mice and WT littermates were instrumented for EEG and EMG recording and implanted with telemetry transmitters for monitoring locomotor activity (LMA) and core body temperature (Tb). Following recovery, mice were administered modafinil (25, 50, 100 mg/kg), caffeine (2.5, 10, 20 mg/kg) or vehicle p.o. at ZT6 in balanced order. In WT mice, both modafinil and caffeine dose-dependently increased LMA for up to 6 h following dosing, whereas only the highest dose of each drug increased LMA in KO mice, and did so for less time after dosing. This effect was particularly pronounced following caffeine, such that total LMA response was significantly attenuated in KO mice compared to WT at all doses of caffeine and did not differ from Vehicle treatment. Tb increased comparably in both genotypes in a dose-dependent manner. TAAR1 deletion was associated with reduced wake consolidation following both drugs, but total time in wakefulness did not differ between KO and WT mice. Furthermore, gamma band EEG activity following both modafinil and caffeine treatment was attenuated in TAAR1 KO compared to WT mice. Our results show that TAAR1 is a critical component of the behavioral and cortical arousal associated with two widely used psychostimulants with very different mechanisms of action. Together with our previous findings, these data suggest that TAAR1 is a previously unrecognized component of an endogenous wake modulating system. PMID- 29456507 TI - The Effects of Vitamin D Supplementation on Signaling Pathway of Inflammation and Oxidative Stress in Diabetic Hemodialysis: A Randomized, Double-Blind, Placebo Controlled Trial. AB - Objective: This study was carried out to determine the effects of vitamin D supplementation on signaling pathway of inflammation and oxidative stress in diabetic hemodialysis (HD) patients. Methods: This randomized double-blind placebo-controlled clinical trial was conducted among 60 diabetic HD patients. Subjects were randomly allocated into two groups to intake either vitamin D supplements at a dosage of 50,000 IU (n = 30) or placebo (n = 30) every 2 weeks for 12 weeks. Gene expression of inflammatory cytokines and biomarkers of oxidative stress were assessed in peripheral blood mononuclear cells (PBMCs) of diabetic HD patients with RT-PCR method. Results: Results of RT-PCR indicated that after the 12-week intervention, compared to the placebo, vitamin D supplementation downregulated gene expression of interleukin (IL)-1beta (P = 0.02), tumor necrosis factor alpha (TNF-alpha) (P = 0.02) and interferon gamma (IFN-gamma) (P = 0.03) in PBMCs of diabetic HD patients. Additionally, vitamin D supplementation, compared to the placebo, downregulated gene expression of transforming growth factor beta (TGF-beta) (P = 0.04), protein kinase C (PKC) (P = 0.001), and mitogen-activated protein kinases 1 (MAPK1) (P = 0.02) in PBMCs of diabetic HD patients. Although not significant, vitamin D supplementation let to a reduction of nuclear factor kappa B (NF-kB) (p = 0.75) expression in PBMCs isolated from diabetic patients compared to the placebo group. There was no statistically significant change following supplementation with vitamin D on gene expression of interleukin (IL)-4, IL-6, and vascular endothelial growth factor (VEGF) in PBMCs of diabetic HD patients. Conclusions: Overall, we found that vitamin D supplementation for 12 weeks among diabetic HD patients had beneficial effects on few gene expression related to inflammation and oxidative stress.

AB - P2X receptors are trimeric eukaryotic ATP-gated cation channels. Extracellular ATP-their physiological ligand-is released as a neurotransmitter and in conditions of cell damage such as inflammation, and substantial evidence implicates P2X receptors in diseases including neuropathic pain, cancer, and arthritis. In 2009, the first P2X crystal structure, Danio rerio P2X4 in the apo- state, was published, and this was followed in 2012 by the ATP-bound structure. These structures transformed our understanding of the conformational changes induced by ATP binding and the mechanism of ligand specificity, and enabled homology modeling of mammalian P2X receptors for ligand docking and rational design of receptor modulators. P2X receptors are attractive drug targets, and a wide array of potent, subtype-selective modulators (mostly antagonists) have been developed. In 2016, crystal structures of human P2X3 in complex with the competitive antagonists TNP-ATP and A-317491, and Ailuropoda melanoleuca P2X7 in complex with a series of allosteric antagonists were published, giving fascinating insights into the mechanism of channel antagonism. In this article we not only summarize current understanding of small-molecule modulator binding at P2X receptors, but also use this information in combination with previously published structure-function data and molecular docking experiments, to hypothesize a role for the dorsal fin loop region in differential ATP potency, and describe novel, testable binding conformations for both the semi-selective synthetic P2X7 agonist 2'-(3')-O-(4-benzoyl)benzoyl ATP (BzATP), and the P2X4 selective positive allosteric modulator ivermectin. We find that the distal benzoyl group of BzATP lies in close proximity to Lys-127, a residue previously implicated in BzATP binding to P2X7, potentially explaining the increased potency of BzATP at rat P2X7 receptors. We also present molecular docking of ivermectin to rat P2X4 receptors, illustrating a plausible binding conformation between the first and second transmembrane domains which not only tallies with previous mutagenesis studies, but would also likely have the effect of stabilizing the open channel structure, consistent with the mode of action of this positive allosteric modulator. From our docking simulations and analysis of sequence homology we propose a series of mutations likely to confer ivermectin sensitivity to human P2X1. PMID- 29456509 TI - Curcumin Inhibits Growth of Human NCI-H292 Lung Squamous Cell Carcinoma Cells by Increasing FOXA2 Expression. AB - Lung squamous cell carcinoma (LSCC) is a common histological lung cancer subtype, but unlike lung adenocarcinoma, limited therapeutic options are available for treatment. Curcumin, a natural compound, may have anticancer effects in various cancer cells, but how it may be used to treat LSCC has not been well studied. Here, we applied curcumin to a human NCI-H292 LSCC cell line to test anticancer effects and explored underlying potential mechanisms of action. Curcumin treatment inhibited NCI-H292 cell growth and increased FOXA2 expression in a time dependent manner. FOXA2 expression was decreased in LSCC tissues compared with adjacent normal tissues and knockdown of FOXA2 increased NCI-H292 cells proliferation. Inhibition of cell proliferation by curcumin was attenuated by FOXA2 knockdown. Moreover inhibition of STAT3 pathways by curcumin increased FOXA2 expression in NCI-H292 cells whereas a STAT3 activator (IL-6) significantly inhibited curcumin-induced FOXA2 expression. Also, SOCS1 and SOCS3, negative regulators of STAT3 activity, were upregulated by curcumin treatment. Thus, curcumin inhibited human NCI-H292 cells growth by increasing FOXA2 expression via regulation of STAT3 signaling pathways. PMID- 29456510 TI - Sodium Tanshinone II-A Sulfonate (DS-201) Induces Vasorelaxation of Rat Mesenteric Arteries via Inhibition of L-Type Ca2+ Channel. AB - Background: We previously have proved that sodium tanshinone II-A sulfonate (DS 201), a derivative of traditional Chinese medicinal herb Danshen (Salvia miltiorrhiza), is an opener and vasodilator of BKCa channel in the vascular smooth muscle cells (VSMCs). Vascular tension is closely associated with Ca2+ dynamics and activation of BKCa channel may not be the sole mechanism for the relaxation of the vascular tension by DS-201. Therefore, we hypothesized that the vasorelaxing effect of DS-20 may be also related to Ca2+ channel and cytoplasmic Ca2+ level in the VSMCs. Methods: Arterial tension was measured by Danish Myo Technology (DMT) myograph system in the mesentery vessels of rats, intracellular Ca2+ level by fluorescence imaging system in the VSMCs of rats, and L-type Ca2+ current by patch clamp technique in Ca2+ channels transfected human embryonic kidney 293 (HEK-293) cells. Results: DS-201 relaxed the endothelium-denuded artery rings pre-constricted with PE or high K+ and the vasorelaxation was reversible. Blockade of K+ channel did not totally block the effect of DS-201 on vasorelaxation. DS-201 suppressed [Ca2+]i transient induced by high K+ in a concentration-dependent manner in the VSMCs, including the amplitude of Ca2+ transient, the time for Ca2+ transient reaching to the [Ca2+]i peak and the time to remove Ca2+ from the cytoplasm. DS-201 inhibited L-type Ca2+ channel with an EC50 of 59.5 MUM and at about 40% efficacy of inhibition. However, DS-201did not significantly affect the kinetics of Ca2+ channel. The effect of DS-201 on L-type Ca2+ channel was rate-independent. Conclusion: The effect of DS-201 on vasorelaxation was not only via activating BKCa channel, but also blocking Ca2+ channel and inhibiting Ca2+ influx in the VSMCs of rats. The results favor the use of DS-201 and Danshen in the treatment of cardiovascular diseases clinically. PMID- 29456511 TI - P2Y12 Receptors in Tumorigenesis and Metastasis. AB - Platelets, beyond their role in hemostasis and thrombosis, may sustain tumorigenesis and metastasis. These effects may occur via direct interaction of platelets with cancer and stromal cells and by the release of several platelet products. Platelets and tumor cells release several bioactive molecules among which a great amount of adenosine triphosphate (ATP) and adenosine diphosphate (ADP). ADP is also formed extracellularly from ATP breakdown by the ecto nucleoside-triphosphate-diphosphohydrolases. Under ATP and ADP stimulation the purinergic P2Y1 receptor (R) initiates platelet activation followed by the ADP P2Y12R-mediated amplification. P2Y12R stimulation amplifies also platelet response to several platelet agonists and to flow conditions, acting as a key positive feed-forward signal in intensifying platelet responses. P2Y12R represents a potential target for an anticancer therapy due to its involvement in platelet-cancer cell crosstalk. Thus, P2Y12R antagonists, including clopidogrel, ticagrelor, and prasugrel, might represent potential anti-cancer agents, in addition to their role as effective antithrombotic drugs. However, further studies, in experimental animals and patients, are required before the recommendation of the use of P2Y12R antagonists in cancer prevention and progression can be made. PMID- 29456512 TI - Local Injections of Superoxide Dismutase Attenuate the Exercise Pressor Reflex in Rats with Femoral Artery Occlusion. AB - The exercise pressor reflex is amplified in patients with peripheral artery disease (PAD) and in an experimental PAD model of rats induced by femoral artery occlusion. Heightened blood pressure worsens the restricted blood flow directed to the limbs in this disease. The purpose of this study was to determine the role played by muscle oxidative stress in regulating the augmented pressor response to static exercise in PAD. We hypothesized that limb ischemia impairs muscle superoxide dismutase (SOD) thereby leading to abnormal autonomic responsiveness observed in PAD animals, and a chronic compensation of SOD for anti-oxidation improves the exaggerated exercise pressor reflex. Our data show that femoral occlusion decreased the protein levels of SOD in ischemic muscle as compared with control muscle. Downregulation of SOD appeared to a greater degree in the oxidative (red) muscle than in the glycolytic (white) muscle under the condition of muscle ischemia. In addition, the exercise pressor response was assessed during electrically induced static contraction. The data demonstrates that the enhancement of the exercise pressor reflex was significantly attenuated after tempol (a mimetic of SOD, 30 mg over a period of 72 h) was administered into the occluded hindlimb. In the occluded rats, mean arterial pressure (MAP) response was 26 +/- 3 mmHg with no tempol and 12 +/- 2 mmHg with tempol application (P < 0.05 vs. group with no tempol; n = 6 in each group). There were no differences in muscle tension development (time-tension index: 12.1 +/- 1.2 kgs with no tempol and 13.5 +/- 1.1 kgs with tempol; P > 0.05 between groups). In conclusion, SOD is lessened in the ischemic muscles and supplement of SOD improves the amplified exercise pressor reflex, which is likely beneficial to the restricted blood flow to the limbs in PAD. PMID- 29456513 TI - Stochastic Effects in Autoimmune Dynamics. AB - Among various possible causes of autoimmune disease, an important role is played by infections that can result in a breakdown of immune tolerance, primarily through the mechanism of "molecular mimicry". In this paper we propose and analyse a stochastic model of immune response to a viral infection and subsequent autoimmunity, with account for the populations of T cells with different activation thresholds, regulatory T cells, and cytokines. We show analytically and numerically how stochasticity can result in sustained oscillations around deterministically stable steady states, and we also investigate stochastic dynamics in the regime of bi-stability. These results provide a possible explanation for experimentally observed variations in the progression of autoimmune disease. Computations of the variance of stochastic fluctuations provide practically important insights into how the size of these fluctuations depends on various biological parameters, and this also gives a headway for comparison with experimental data on variation in the observed numbers of T cells and organ cells affected by infection. PMID- 29456515 TI - Relating (Un)acceptability to Interpretation. Experimental Investigations on Negation. AB - Although contemporary linguistic studies routinely use unacceptable sentences to determine the boundary of what falls outside the scope of grammar, investigations far more rarely take into consideration the possible interpretations of such sentences, perhaps because these interpretations are commonly prejudged as irrelevant or unreliable across speakers. In this paper we provide the results of two experiments in which participants had to make parallel acceptability and interpretation judgments of sentences presenting various types of negative dependencies in Basque and in two varieties of Spanish (Castilian Spanish and Basque Country Spanish). Our results show that acceptable sentences are uniformly assigned a single negation reading in the two languages. However, while unacceptable sentences consistently convey single negation in Basque, they are interpreted at chance in both varieties of Spanish. These results confirm that judgment data that distinguish between acceptable and unacceptable negative utterances can inform us not only about an adult's grammar of his/her particular language but also about interesting cross-linguistic differences. We conclude that the acceptability and interpretation of (un)grammatical negative sentences can serve linguistic theory construction by helping to disentangle basic assumptions about the nature of various negative dependencies. PMID- 29456514 TI - Right Frontotemporal Cortex Mediates the Relationship between Cognitive Insight and Subjective Quality of Life in Patients with Schizophrenia. AB - Although prior studies identified a relationship between cognitive insight and subjective quality of life (QOL) in patients with schizophrenia, the brain regions mediating this relationship remain unknown. Recent studies have shown that the ventrolateral prefrontal cortex may be particularly important for cognitive insight in individuals with schizophrenia. Here, we examined whether frontotemporal function mediates the relationship between cognitive insight and QOL in 64 participants, including 32 patients with schizophrenia and 32 healthy controls. Cognitive insight was measured using the Beck Cognitive Insight Scale (BCIS), while participants' subjective QOL was assessed using the Medical Outcomes Study 36-item Short-form Health Survey. Frontotemporal function was evaluated during a verbal fluency task using multichannel near-infrared spectroscopy. Consistent with previous findings, we found that frontotemporal function was impaired in patients with schizophrenia. Interestingly, our data also revealed that the right ventrolateral PFC and the right anterior part of the temporal cortex significantly mediated the relationship between the self reflectiveness (SR) subscale of the BCIS and subjective QOL. These findings suggest that cognitive insight, particularly SR, is associated with subjective QOL in patients with schizophrenia via right frontotemporal function. The findings of this study provide important insight into a QOL model of schizophrenia, which may guide the development of cost-effective interventions that target frontotemporal function in patients with schizophrenia.

AB - Humans are born completely dependent on adult care for survival. To get the necessary support, newborns rely on socio-communicative abilities which have both innate and learned components. Maternal responsiveness (MR), as a critical aspect of mother-infant interaction, is a robust predictor of the acquisition of socio communicative abilities. However, maternal responsiveness (MR) is influenced by parity, since mothers rely on a limited capacity of cognitive control for efficient attachment with their offspring. This fact is of particular concern for preterms, whose developing brain already faces many challenges due to their premature emergence from the womb's controlled environment and may still have to compete with siblings for mother's attention. Thus, in the present work, we aimed to understand how parity interferes with MR and whether it affects the development of socio-communicative abilities of preterm infants. We used the Social Interaction Rating Scale (SIRS) and the mother-child observation protocol in 18 dyads with gestational age <36 weeks. Dyads were separated into three groups: primiparous with twin pregnancy (TPM), primiparous (PM), and multiparous (MP). Dyadic behavior was evaluated at 3, 6, 9, and 12 months. Our results show that offspring size affects MR, but not the socio-communicative development of preterm infants during the first year, suggesting a level of resilience of brain systems supporting the attachment to caregivers.

AB - Background: This daily diary study investigates the phenomenon of bedtime procrastination. Bedtime procrastination is defined as going to bed later than intended, without having external reasons for doing so. We highlight the role chronotype (interindividual differences in biological preferences for sleep-wake times) plays for bedtime procrastination. Moreover, we challenge the view that bedtime procrastination is the result of a lack of self-regulatory resources by investigating momentary self-regulatory resources as a predictor of day-specific bedtime procrastination. Methods: One-hundred and eight employees working in various industries completed a general electronic questionnaire (to assess chronotype and trait self-control) and two daily electronic questionnaires (to assess momentary self-regulatory resources before going to bed and day-specific bedtime procrastination) over the course of five work days, resulting in 399 pairs of matched day-next-day measurements. Results: Results of multilevel regression analyses showed that later chronotypes (also referred to as evening types or 'owls') tended to report more bedtime procrastination on work days. Moreover, for late chronotypes, day-specific bedtime procrastination declined over the course of the work week. This pattern is in line with expectations derived from chronobiology and could not be explained by trait self-control. In addition, on evenings on which employees had less self-regulatory resources available before going to bed-compared to evenings on which they had more self regulatory resources available before going to bed-employees showed lower bedtime procrastination. This finding contradicts the prevailing idea that bedtime procrastination is the result of a lack of self-regulatory resources. Conclusion: The findings of this study provide important implications for how bedtime procrastination should be positioned in the field of procrastination as self regulatory failure and for how bedtime procrastination should be dealt with in practice.

PMID- 29456522 TI - Post-Traumatic Hypopituitarism-Who Should Be Screened, When, and How? AB - Traumatic brain injury (TBI) remains a major, global public health concern. Over the last 15 years, a significant body of evidence has emerged demonstrating that post-traumatic hypopituitarism (PTHP) is a common and clinically significant consequence of TBI. Non-specific symptomology and the lack of an agreed approach to screening for PTHP has led to significant under-diagnosis of this debilitating disease. In this review, we will discuss the frequency and clinical significance of acute and chronic PTHP as described in the current literature highlighting the evidence base for screening and hormone replacement in these patients. We will also offer a pragmatic approach to identifying relevant anterior pituitary dysfunction after TBI and a follow-up strategy for those patients. Specific controversies and remaining unanswered questions will be addressed. PMID- 29456521 TI - Mathematical Modeling of Protein Misfolding Mechanisms in Neurological Diseases: A Historical Overview. AB - Protein misfolding refers to a process where proteins become structurally abnormal and lose their specific 3-dimensional spatial configuration. The histopathological presence of misfolded protein (MP) aggregates has been associated as the primary evidence of multiple neurological diseases, including Prion diseases, Alzheimer's disease, Parkinson's disease, and Creutzfeldt-Jacob disease. However, the exact mechanisms of MP aggregation and propagation, as well as their impact in the long-term patient's clinical condition are still not well understood. With this aim, a variety of mathematical models has been proposed for a better insight into the kinetic rate laws that govern the microscopic processes of protein aggregation. Complementary, another class of large-scale models rely on modern molecular imaging techniques for describing the phenomenological effects of MP propagation over the whole brain. Unfortunately, those neuroimaging based studies do not take full advantage of the tremendous capabilities offered by the chemical kinetics modeling approach. Actually, it has been barely acknowledged that the vast majority of large-scale models have foundations on previous mathematical approaches that describe the chemical kinetics of protein replication and propagation. The purpose of the current manuscript is to present a historical review about the development of mathematical models for describing both microscopic processes that occur during the MP aggregation and large-scale events that characterize the progression of neurodegenerative MP-mediated diseases. PMID- 29456524 TI - Saccharomyces cerevisiae and S. kudriavzevii Synthetic Wine Fermentation Performance Dissected by Predictive Modeling. AB - Wineries face unprecedented challenges due to new market demands and climate change effects on wine quality. New yeast starters including non-conventional Saccharomyces species, such as S. kudriavzevii, may contribute to deal with some of these challenges. The design of new fermentations using non-conventional yeasts requires an improved understanding of the physiology and metabolism of these cells. Dynamic modeling brings the potential of exploring the most relevant mechanisms and designing optimal processes more systematically. In this work we explore mechanisms by means of a model selection, reduction and cross-validation pipeline which enables to dissect the most relevant fermentation features for the species under consideration, Saccharomyces cerevisiae T73 and Saccharomyces kudriavzevii CR85. The pipeline involved the comparison of a collection of models which incorporate several alternative mechanisms with emphasis on the inhibitory effects due to temperature and ethanol. We focused on defining a minimal model with the minimum number of parameters, to maximize the identifiability and the quality of cross-validation. The selected model was then used to highlight differences in behavior between species. The analysis of model parameters would indicate that the specific growth rate and the transport of hexoses at initial times are higher for S. cervisiae T73 while S. kudriavzevii CR85 diverts more flux for glycerol production and cellular maintenance. As a result, the fermentations with S. kudriavzevii CR85 are typically slower; produce less ethanol but higher glycerol. Finally, we also explored optimal initial inoculation and process temperature to find the best compromise between final product characteristics and fermentation duration. Results reveal that the production of glycerol is distinctive in S. kudriavzevii CR85, it was not possible to achieve the same production of glycerol with S. cervisiae T73 in any of the conditions tested. This result brings the idea that the optimal design of mixed cultures may have an enormous potential for the improvement of final wine quality. PMID- 29456525 TI - Kinetics and Novel Degradation Pathway of Permethrin in Acinetobacter baumannii ZH-14. AB - Persistent use of permethrin has resulted in its ubiquitous presence as a contaminant in surface streams and soils, yet little is known about the kinetics and metabolic behaviors of this pesticide. In this study, a novel bacterial strain Acinetobacter baumannii ZH-14 utilizing permethrin via partial hydrolysis pathways was isolated from sewage sludge. Response surface methodology based on Box-Behnken design of cultural conditions was used for optimization resulting in 100% degradation of permethrin (50 mg.L-1) within 72 h. Strain ZH-14 degraded permethrin up to a concentration of 800 mg.L-1. Biodegradation kinetics analysis indicated that permethrin degradation by this strain was concentration dependent, with a maximum specific degradation rate, half-saturation constant, and inhibition constant of 0.0454 h-1, 4.7912 mg.L-1, and 367.2165 mg.L-1, respectively. High-performance liquid chromatography and gas chromatography-mass spectrometry identified 3-phenoxybenzenemethanol and 3-phenoxybenzaldehyde as the major intermediate metabolites of the permethrin degradation pathway. Bioaugmentation of permethrin-contaminated soils with strain ZH-14 significantly enhanced degradation, and over 85% of permethrin was degraded within 9 days with the degradation process following the first-order kinetic model. In addition to degradation of permethrin, strain ZH-14 was capable of degrading a large range of synthetic pyrethroids such as deltamethrin, bifenthrin, fenpropathrin, cyhalothrin, and beta-cypermethrin which are also widely used pesticides with environmental contamination problems, suggesting the promising potentials of A. baumannii ZH-14 in bioremediation of pyrethroid-contaminated terrestrial and aquatic environments. PMID- 29456523 TI - G Protein-Coupled Receptors As Regulators of Localized Translation: The Forgotten Pathway? AB - G protein-coupled receptors (GPCRs) exert their physiological function by transducing a complex signaling network that coordinates gene expression and dictates the phenotype of highly differentiated cells. Much is known about the gene networks they transcriptionally regulate upon ligand exposure in a process that takes hours before a new protein is synthesized. However, far less is known about GPCR impact on the translational machinery and subsequent mRNA translation, although this gene regulation level alters the cell phenotype in a strikingly different timescale. In fact, mRNA translation is an early response kinetically connected to signaling events, hence it leads to the synthesis of a new protein within minutes following receptor activation. By these means, mRNA translation is responsive to subtle variations of the extracellular environment. In addition, when restricted to cell subcellular compartments, local mRNA translation contributes to cell micro-specialization, as observed in synaptic plasticity or in cell migration. The mechanisms that control where in the cell an mRNA is translated are starting to be deciphered. But how an extracellular signal triggers such local translation still deserves extensive investigations. With the advent of high-throughput data acquisition, it now becomes possible to review the current knowledge on the translatome that some GPCRs regulate, and how this information can be used to explore GPCR-controlled local translation of mRNAs. PMID- 29456526 TI - Ammonia-Oxidizing Archaea and Bacteria Differentially Contribute to Ammonia Oxidation in Sediments from Adjacent Waters of Rushan Bay, China. AB - Ammonia oxidation plays a significant role in the nitrogen cycle in marine sediments. Ammonia-oxidizing archaea (AOA) and bacteria (AOB) are the key contributors to ammonia oxidation, and their relative contribution to this process is one of the most important issues related to the nitrogen cycle in the ocean. In this study, the differential contributions of AOA and AOB to ammonia oxidation in surface sediments from adjacent waters of Rushan Bay were studied based on the ammonia monooxygenase (amoA) gene. Molecular biology techniques were used to analyze ammonia oxidizers' community characteristics, and potential nitrification incubation was applied to understand the ammonia oxidizers' community activity. The objective was to determine the community structure and activity of AOA and AOB in surface sediments from adjacent waters of Rushan Bay and to discuss the different contributions of AOA and AOB to ammonia oxidation during summer and winter seasons in the studied area. Pyrosequencing analysis revealed that the diversity of AOA was higher than that of AOB. The majority of AOA and AOB clustered into Nitrosopumilus and Nitrosospira, respectively, indicating that the Nitrosopumilus group and Nitrosospira groups may be more adaptable in studied sediments. The AOA community was closely correlated to temperature, salinity and ammonium concentration, whereas the AOB community showed a stronger correlation with temperature, chlorophyll-a content (chla) and nitrite concentration. qPCR results showed that both the abundance and the transcript abundance of AOA was consistently greater than that of AOB. AOA and AOB differentially contributed to ammonia oxidation in different seasons. AOB occupied the dominant position in mediating ammonia oxidation during summer, while AOA might play a dominant role in ammonia oxidation during winter. PMID- 29456527 TI - Light as a Broad-Spectrum Antimicrobial. AB - Antimicrobial resistance is a significant and growing concern. To continue to treat even simple infections, there is a pressing need for new alternative and complementary approaches to antimicrobial therapy. One possible addition to the current range of treatments is the use of narrow-wavelength light as an antimicrobial, which has been shown to eliminate a range of common pathogens. Much progress has already been made with blue light but the potential of other regions of the electromagnetic spectrum is largely unexplored. In order that the approach can be fully and most effectively realized, further research is also required into the effects of energy dose, the harmful and beneficial impacts of light on eukaryotic tissues, and the role of oxygen in eliciting microbial toxicity. These and other topics are discussed within this perspective. PMID- 29456528 TI - Mutation in ESBL Plasmid from Escherichia coli O104:H4 Leads Autoagglutination and Enhanced Plasmid Dissemination. AB - Conjugative plasmids are one of the main driving force of wide-spreading of multidrug resistance (MDR) bacteria. They are self-transmittable via conjugation as carrying the required set of genes and cis-acting DNA locus for direct cell-to cell transfer. IncI incompatibility plasmids are nowadays often associated with extended-spectrum beta-lactamases producing Enterobacteria in clinic and environment. pESBL-EA11 was isolated from Escherichia coli O104:H4 outbreak strain in Germany in 2011. During the previous study identifying transfer genes of pESBL-EA11, it was shown that transposon insertion at certain DNA region of the plasmid, referred to as Hft, resulted in great enhancement of transfer ability. This suggested that genetic modifications can enhance dissemination of MDR plasmids. Such 'superspreader' mutations have attracted little attention so far despite their high potential to worsen MDR spreading. Present study aimed to gain our understanding on regulatory elements that involved pESBL transfer. While previous studies of IncI plasmids indicated that immediate downstream gene of Hft, traA, is not essential for conjugative transfer, here we showed that overexpression of TraA in host cell elevated transfer rate of pESBL-EA11. Transposon insertion or certain nucleotide substitutions in Hft led strong TraA overexpression which resulted in activation of essential regulator TraB and likely overexpression of conjugative pili. Atmospheric Scanning Electron Microscopy observation suggested that IncI pili are distinct from other types of conjugative pili (such as long filamentous F-type pili) and rather expressed throughout the cell surface. High transfer efficiency in the mutant pESBL-EA11 was involved with hyperpiliation which facilitates cell-to-cell adhesion, including autoagglutination. The capability of plasmids to evolve to highly transmissible mutant is alarming, particularly it might also have adverse effect on host pathogenicity. PMID- 29456529 TI - Challenges and Opportunities for Biomarkers of Clinical Response to AHSCT in Autoimmunity. AB - Autoimmunity represents a broad category of diseases that involve a variety of organ targets and distinct autoantigens. For patients with autoimmune diseases who fail to respond to approved disease-modifying treatments, autologous hematopoietic stem cell transplantation (AHSCT) after high-dose immunosuppressive therapy provides an alternative strategy. Although more than 100 studies have been published on AHSCT efficacy in autoimmunity, the mechanisms that confer long term disease remission as opposed to continued deterioration or disease reactivation remain to be determined. In a phase II clinical trial, high-dose immunosuppressive therapy combined with autologous CD34+ hematopoietic stem cell transplant in treatment-resistant, relapsing-remitting multiple sclerosis (RRMS) resulted in 69.2% of participants achieving long-term remission through 60 months follow-up. Flow cytometry data from the 24 transplanted participants in the high dose immunosuppression and autologous stem cell transplantation for poor prognosis multiple sclerosis (HALT-MS) trial are presented to illustrate immune reconstitution out to 36 months in patients with aggressive RRMS treated with AHSCT and to highlight experimental challenges inherent in identifying biomarkers for relapse and long-term remission through 60 months follow-up. AHSCT induced changes in numbers of CD4 T cells and in the composition of CD4 and CD8 T cells that persisted through 36 months in participants who maintained disease remission through 60 months. However, changes in T cell phenotypes studied were unable to clearly discriminate durable remission from disease reactivation after AHSCT, possibly due to the small sample size, limited phenotypes evaluated in this real time assay, and other limitations of the HALT-MS study population. Strategies and future opportunities for identifying biomarkers of clinical outcome to AHSCT in autoimmunity are also discussed. PMID- 29456530 TI - Donor Genotype in the Interleukin-7 Receptor alpha-Chain Predicts Risk of Graft versus-Host Disease and Cytomegalovirus Infection after Allogeneic Hematopoietic Stem Cell Transplantation. AB - The efficacy of allogeneic hematopoietic stem cell transplantation (HSCT) is challenged by acute and chronic graft-versus-host disease (aGVHD and cGVHD) and viral infections due to long-lasting immunodeficiency. Interleukin-7 (IL-7) is a cytokine essential for de novo T cell generation in thymus and peripheral T cell homeostasis. In this study, we investigated the impact of the single nucleotide polymorphism rs6897932 in the IL-7 receptor alpha-chain (IL-7Ralpha) which has previously been associated with several autoimmune diseases. We included 460 patients undergoing allogeneic HSCT after a myeloablative conditioning. Patients had a median age of 26.3 years (0.3-67.0 years), and 372 (80.9%) underwent HSCT for malignant diseases. Donors were matched sibling donors (n = 147), matched unrelated donors (n = 244) or mismatched unrelated donors (n = 69), and the stem cell source were either bone marrow (n = 329) or peripheral blood (n = 131). DNA from donors was genotyped for the IL-7Ralpha single nucleotide polymorphism (SNP) rs6897932 using an allele-specific primer extension assay (CC: n = 252, CT: n = 178, TT: n = 30). The donor T allele was associated with a higher risk of grades III-IV aGVHD (HR = 2.0, 95% CI = 1.1-3.8, P = 0.034) and with significantly increased risk of extensive cGVHD (HR = 2.0, 95% CI = 1.1-3.6, P = 0.025) after adjustment for potential risk factors. In addition, the TT genotype was associated with a higher risk of cytomegalovirus (CMV) infection post-transplant (HR = 2.4, 95% CI = 1.2-4.3, P = 0.0068). Numbers of T cells were significantly higher on day +60 in patients receiving a rs6897932 TT graft (CD3+: 109% increase, P = 0.0096; CD4+: 64% increase, P = 0.038; CD8+: 133% increase, P = 0.011). Donor heterozygosity for the T allele was associated with inferior overall survival (HR = 1.7, 95% CI = 1.2-2.3, P = 0.0027) and increased treatment related mortality (HR = 2.3, 95% CI = 1.3-4.0, P = 0.0047), but was not associated with the risk of relapse (P = 0.35). In conclusion, the IL-7Ralpha rs6897932 genotype of the donor is predictive of aGVHD and cGVHD, CMV infection, and mortality following HSCT. These findings indicate that IL-7Ralpha SNP typing of donors may optimize donor selection and facilitate individualization of treatment in order to limit treatment-related complications. PMID- 29456531 TI - First Occurrence of Plasmablastic Lymphoma in Adenosine Deaminase-Deficient Severe Combined Immunodeficiency Disease Patient and Review of the Literature. AB - Adenosine deaminase-deficient severe combined immunodeficiency disease (ADA-SCID) is a primary immune deficiency characterized by mutations in the ADA gene resulting in accumulation of toxic compounds affecting multiple districts. Hematopoietic stem cell transplantation (HSCT) from a matched donor and hematopoietic stem cell gene therapy are the preferred options for definitive treatment. Enzyme replacement therapy (ERT) is used to manage the disease in the short term, while a decreased efficacy is reported in the medium-long term. To date, eight cases of lymphomas have been described in ADA-SCID patients. Here we report the first case of plasmablastic lymphoma occurring in a young adult with ADA-SCID on long-term ERT, which turned out to be Epstein-Barr virus associated. The patient previously received infusions of genetically modified T cells. A cumulative analysis of the eight published cases of lymphoma from 1992 to date, and the case here described, reveals a high mortality (89%). The most common form is diffuse large B-cell lymphoma, which predominantly occurs in extra nodal sites. Seven cases occurred in patients on ERT and two after haploidentical HSCT. The significant incidence of immunodeficiency-associated lymphoproliferative disorders and poor survival of patients developing this complication highlight the priority in finding a prompt curative treatment for ADA-SCID. PMID- 29456532 TI - A Stretch of Negatively Charged Amino Acids of Linker for Activation of T-Cell Adaptor Has a Dual Role in T-Cell Antigen Receptor Intracellular Signaling. AB - The adaptor protein linker for activation of T cells (LAT) has an essential role transducing activatory intracellular signals coming from the TCR/CD3 complex. Previous reports have shown that upon T-cell activation, LAT interacts with the tyrosine kinase Lck, leading to the inhibition of its kinase activity. LAT-Lck interaction seemed to depend on a stretch of negatively charged amino acids in LAT. Here, we have substituted this segment of LAT between amino acids 113 and 126 with a non-charged segment and expressed the mutant LAT (LAT-NIL) in J.CaM2 cells in order to analyze TCR signaling. Substitution of this segment in LAT prevented the activation-induced interaction with Lck. Moreover, cells expressing this mutant form of LAT showed a statistically significant increase of proximal intracellular signals such as phosphorylation of LAT in tyrosine residues 171 and 191, and also enhanced ZAP70 phosphorylation approaching borderline statistical significance (p = 0.051). Nevertheless, downstream signals such as Ca2+ influx or MAPK pathways were partially inhibited. Overall, our data reveal that LAT-Lck interaction constitutes a key element regulating proximal intracellular signals coming from the TCR/CD3 complex. PMID- 29456533 TI - Non-Hematopoietic MLKL Protects Against Salmonella Mucosal Infection by Enhancing Inflammasome Activation. AB - The intestinal mucosal barrier is critical for host defense against pathogens infection. Here, we demonstrate that the mixed lineage kinase-like protein (MLKL), a necroptosis effector, promotes intestinal epithelial barrier function by enhancing inflammasome activation. MLKL-/- mice were more susceptible to Salmonella infection compared with wild-type counterparts, with higher mortality rates, increased body weight loss, exacerbated intestinal inflammation, more bacterial colonization, and severe epithelial barrier disruption. MLKL deficiency promoted early epithelial colonization of Salmonella prior to developing apparent intestinal pathology. Active MLKL was predominantly expressed in crypt epithelial cells, and experiments using bone marrow chimeras found that the protective effects of MLKL were dependent on its expression in non-hematopoietic cells. Intestinal mucosa of MLKL-/- mice had impaired caspase-1 and gasdermin D cleavages and decreased interleukin (IL)-18 release. Moreover, administration of exogenous recombinant IL-18 rescued the phenotype of increased bacterial colonization in MLKL-/- mice. Thus, our results uncover the role of MLKL in enhancing inflammasome activation in intestinal epithelial cells to inhibit early bacterial colonization. PMID- 29456534 TI - Critical Role of TGF-beta and IL-2 Receptor Signaling in Foxp3 Induction by an Inhibitor of DNA Methylation. AB - Under physiological conditions, CD4+ regulatory T (Treg) cells expressing the transcription factor Foxp3 are generated in the thymus [thymus-derived Foxp3+ Treg (tTregs) cells] and extrathymically at peripheral sites [peripherally induced Foxp3+ Treg (pTreg) cell], and both developmental subsets play non redundant roles in maintaining self-tolerance throughout life. In addition, a variety of experimental in vitro and in vivo modalities can extrathymically elicit a Foxp3+ Treg cell phenotype in peripheral CD4+Foxp3- T cells, which has attracted much interest as an approach toward cell-based therapy in clinical settings of undesired immune responses. A particularly notable example is the in vitro induction of Foxp3 expression and Treg cell activity (iTreg cells) in initially naive CD4+Foxp3- T cells through T cell receptor (TCR) and IL-2R ligation, in the presence of exogenous TGF-beta. Clinical application of Foxp3+ iTreg cells has been hampered by the fact that TGF-beta-driven Foxp3 induction is not sufficient to fully recapitulate the epigenetic and transcriptional signature of in vivo induced Foxp3+ tTreg and pTreg cells, which includes the failure to imprint iTreg cells with stable Foxp3 expression. This hurdle can be potentially overcome by pharmacological interference with DNA methyltransferase activity and CpG methylation [e.g., by the cytosine nucleoside analog 5-aza-2'-deoxycytidine (5-aza-dC)] to stabilize TGF-beta-induced Foxp3 expression and to promote a Foxp3+ iTreg cell phenotype even in the absence of added TGF-beta. However, the molecular mechanisms of 5-aza-dC-mediated Foxp3+ iTreg cell generation have remained incompletely understood. Here, we show that in the absence of exogenously added TGF-beta and IL-2, efficient 5-aza-dC-mediated Foxp3+ iTreg cell generation from TCR-stimulated CD4+Foxp3- T cells is critically dependent on TGF-betaR and IL-2R signaling and that this process is driven by TGF-beta and IL 2, which could either be FCS derived or produced by T cells on TCR stimulation. Overall, these findings contribute to our understanding of the molecular mechanisms underlying the process of Foxp3 induction and may provide a rational basis for generating phenotypically and functionally stable iTreg cells. PMID- 29456535 TI - Liver X Receptor Agonist Therapy Prevents Diffuse Alveolar Hemorrhage in Murine Lupus by Repolarizing Macrophages. AB - : The generation of CD138+ phagocytic macrophages with an alternative (M2) phenotype that clear apoptotic cells from tissues is defective in lupus. Liver X receptor-alpha (LXRalpha) is an oxysterol-regulated transcription factor that promotes reverse cholesterol transport and alternative (M2) macrophage activation. Conversely, hypoxia-inducible factor 1-alpha (HIF1alpha) promotes classical (M1) macrophage activation. The objective of this study was to see if lupus can be treated by enhancing the generation of M2-like macrophages using LXR agonists. Peritoneal macrophages from pristane-treated mice had an M1 phenotype, high HIFalpha-regulated phosphofructokinase and TNFalpha expression (quantitative PCR, flow cytometry), and low expression of the LXRalpha-regulated gene ATP binding cassette subfamily A member 1 (Abca1) and Il10 vs. mice treated with mineral oil, a control inflammatory oil that does not cause lupus. Glycolytic metabolism (extracellular flux assays) and Hif1a expression were higher in pristane-treated mice (M1-like) whereas oxidative metabolism and LXRalpha expression were higher in mineral oil-treated mice (M2-like). Similarly, lupus patients' monocytes exhibited low LXRalpha/ABCA1 and high HIF1alpha vs. CONTROLS: The LXR agonist T0901317 inhibited type I interferon and increased ABCA1 in lupus patients' monocytes and in murine peritoneal macrophages. In vivo, T0901317 induced M2-like macrophage polarization and protected mice from diffuse alveolar hemorrhage (DAH), an often fatal complication of lupus. We conclude that end organ damage (DAH) in murine lupus can be prevented using an LXR agonist to correct a macrophage differentiation abnormality characteristic of lupus. LXR agonists also decrease inflammatory cytokine production by human lupus monocytes, suggesting that these agents may be have a role in the pharmacotherapy of lupus. PMID- 29456536 TI - Janus-Faced Myeloid-Derived Suppressor Cell Exosomes for the Good and the Bad in Cancer and Autoimmune Disease. AB - Myeloid-derived suppressor cells (MDSCs) are a heterogeneous population of immature myeloid cells originally described to hamper immune responses in chronic infections. Meanwhile, they are known to be a major obstacle in cancer immunotherapy. On the other hand, MDSC can interfere with allogeneic transplant rejection and may dampen autoreactive T cell activity. Whether MDSC-Exosomes (Exo) can cope with the dangerous and potentially therapeutic activities of MDSC is not yet fully explored. After introducing MDSC and Exo, it will be discussed, whether a blockade of MDSC-Exo could foster the efficacy of immunotherapy in cancer and mitigate tumor progression supporting activities of MDSC. It also will be outlined, whether application of native or tailored MDSC-Exo might prohibit autoimmune disease progression. These considerations are based on the steadily increasing knowledge on Exo composition, their capacity to distribute throughout the organism combined with selectivity of targeting, and the ease to tailor Exo and includes open questions that answers will facilitate optimizing protocols for a MDSC-Exo blockade in cancer as well as for strengthening their therapeutic efficacy in autoimmune disease. PMID- 29456537 TI - Understanding Progressive Multifocal Leukoencephalopathy Risk in Multiple Sclerosis Patients Treated with Immunomodulatory Therapies: A Bird's Eye View. AB - The increased use of newer potent immunomodulatory therapies for multiple sclerosis (MS), including natalizumab, fingolimod, and dimethyl fumarate, has expanded the patient population at risk for developing progressive multifocal leukoencephalopathy (PML). These MS therapies shift the profile of lymphocytes within the central nervous system (CNS) leading to increased anti-inflammatory subsets and decreased immunosurveillance. Similar to MS, PML is a demyelinating disease of the CNS, but it is caused by the JC virus. The manifestation of PML requires the presence of an active, genetically rearranged form of the JC virus within CNS glial cells, coupled with the loss of appropriate JC virus-specific immune responses. The reliability of metrics used to predict risk for PML could be improved if all three components, i.e., viral genetic strain, localization, and host immune function, were taken into account. Advances in our understanding of the critical lymphocyte subpopulation changes induced by these MS therapies and ability to detect viral mutation and reactivation will facilitate efforts to develop these metrics. PMID- 29456538 TI - An Uncoupling of Canonical Phenotypic Markers and Functional Potency of Ex Vivo Expanded Natural Killer Cells. AB - Recent advances in cellular therapies for patients with cancer, including checkpoint blockade and ex vivo-expanded, tumor-specific T cells, have demonstrated that targeting the immune system is a powerful approach to the elimination of tumor cells. Clinical efforts have also demonstrated limitations, however, including the potential for tumor cell antigenic drift and neoantigen formation, which promote tumor escape and recurrence, as well as rapid onset of T cell exhaustion in vivo. These findings suggest that antigen unrestricted cells, such as natural killer (NK) cells, may be beneficial for use as an alternative to or in combination with T cell based approaches. Although highly effective in lysing transformed cells, to date, few clinical trials have demonstrated antitumor function or persistence of transferred NK cells. Several recent studies describe methods to expand NK cells for adoptive transfer, although the effects of ex vivo expansion are not fully understood. We therefore explored the impact of a clinically validated 12-day expansion protocol using a K562 cell line expressing membrane-bound IL-15 and 4-1BB ligand with high-dose soluble IL-2 on the phenotype and functions of NK cells from healthy donors. Following expansions using this protocol, we found expression of surface proteins that implicate preferential expansion of NK cells that are not fully mature, as is typically associated with highly cytotoxic NK cell subsets. Despite increased expression of markers associated with functional exhaustion in T cells, we found that ex vivo expanded NK cells retained cytokine production capacity and had enhanced tumor cell cytotoxicity. The preferential expansion of an NK cell subset that is phenotypically immature and functionally pleiotropic suggests that adoptively transferred cells may persist better in vivo when compared with previous methods using this approach. Ex vivo expansion does not quell killer immunoglobulin-like receptor diversity, allowing responsiveness to various factors in vivo that may influence activation and inhibition. Collectively, our data suggest that in addition to robust NK cell expansion that has been described using this method, expanded NK cells may represent an ideal cell therapy that is longer lived, highly potent, and responsive to an array of activating and inhibitory signals. PMID- 29456539 TI - Generation of Human Immunosuppressive Myeloid Cell Populations in Human Interleukin-6 Transgenic NOG Mice. AB - The tumor microenvironment contains unique immune cells, termed myeloid-derived suppressor cells (MDSCs), and tumor-associated macrophages (TAMs) that suppress host anti-tumor immunity and promote tumor angiogenesis and metastasis. Although these cells are considered a key target of cancer immune therapy, in vivo animal models allowing differentiation of human immunosuppressive myeloid cells have yet to be established, hampering the development of novel cancer therapies. In this study, we established a novel humanized transgenic (Tg) mouse strain, human interleukin (hIL)-6-expressing NOG mice (NOG-hIL-6 transgenic mice). After transplantation of human hematopoietic stem cells (HSCs), the HSC-transplanted NOG-hIL-6 Tg mice (HSC-NOG-hIL-6 Tg mice) showed enhanced human monocyte/macrophage differentiation. A significant number of human monocytes were negative for HLA-DR expression and resembled immature myeloid cells in the spleen and peripheral blood from HSC-NOG-hIL-6 Tg mice, but not from HSC-NOG non-Tg mice. Engraftment of HSC4 cells, a human head and neck squamous cell carcinoma derived cell line producing various factors including IL-6, IL-1beta, macrophage colony-stimulating factor (M-CSF), and vascular endothelial growth factor (VEGF), into HSC-NOG-hIL-6 Tg mice induced a significant number of TAM-like cells, but few were induced in HSC-NOG non-Tg mice. The tumor-infiltrating macrophages in HSC-NOG-hIL-6 Tg mice expressed a high level of CD163, a marker of immunoregulatory myeloid cells, and produced immunosuppressive molecules such as arginase-1 (Arg-1), IL-10, and VEGF. Such cells from HSC-NOG-hIL-6 Tg mice, but not HSC-NOG non-Tg mice, suppressed human T cell proliferation in response to antigen stimulation in in vitro cultures. These results suggest that functional human TAMs can be developed in NOG-hIL-6 Tg mice. This mouse model will contribute to the development of novel cancer immune therapies targeting immunoregulatory/immunosuppressive myeloid cells. PMID- 29456540 TI - Kallikrein-Kinin System Suppresses Type I Interferon Responses: A Novel Pathway of Interferon Regulation. AB - The Kallikrein-Kinin System (KKS), comprised of kallikreins (klks), bradykinins (BKs) angiotensin-converting enzyme (ACE), and many other molecules, regulates a number of physiological processes, including inflammation, coagulation, angiogenesis, and control of blood pressure. In this report, we show that KKS regulates Type I IFN responses, thought to be important in lupus pathogenesis. We used CpG (TLR9 ligand), R848 (TLR7 ligand), or recombinant IFN-alpha to induce interferon-stimulated genes (ISGs) and proteins, and observed that this response was markedly diminished by BKs, klk1 (tissue kallikrein), or captopril (an ACE inhibitor). BKs significantly decreased the ISGs induced by TLRs in vitro and in vivo (in normal and lupus-prone mice), and in human PBMCs, especially the induction of Irf7 gene (p < 0.05), the master regulator of Type I IFNs. ISGs induced by IFN-alpha were also suppressed by the KKS. MHC Class I upregulation, a classic response to Type I IFNs, was reduced by BKs in murine dendritic cells (DCs). BKs decreased phosphorylation of STAT2 molecules that mediate IFN signaling. Among the secreted pro-inflammatory cytokines/chemokines analyzed (IL 6, IL12p70, and CXCL10), the strongest suppressive effect was on CXCL10, a highly Type I IFN-dependent cytokine, upon CpG stimulation, both in normal and lupus prone DCs. klks that break down into BKs, also suppressed CpG-induced ISGs in murine DCs. Captopril, a drug that inhibits ACE and increases BK, suppressed ISGs, both in mouse DCs and human PBMCs. The effects of BK were reversed with indomethacin (compound that inhibits production of PGE2), suggesting that BK suppression of IFN responses may be mediated via prostaglandins. These results highlight a novel regulatory mechanism in which members of the KKS control the Type I IFN response and suggest a role for modulators of IFNs in the pathogenesis of lupus and interferonopathies.

PMID- 29456541 TI - IFN-tau Mediated Control of Bovine Major Histocompatibility Complex Class I Expression and Function via the Regulation of bta-miR-148b/152 in Bovine Endometrial Epithelial Cells. AB - IFN-tau, a type I interferon produced by the trophoblasts of ruminants, has various important immune functions, including effects on the expression of major histocompatibility complex (MHC) class I (MHC-I). A previous study has reported that IFN-tau promotes the expression of MHC-I molecules on endometrial cells. However, the immunological mechanisms by which IFN-tau regulates MHC-I molecules remain unknown. Here, we investigated which microRNA (miRNAs) may be involved in the regulation of MHC-I molecule expression and function in bovine endometrial epithelial cells (bEECs). By using TargetScan 6.2 and http://www.microRNA.org, two miRNAs were suggested to target the 3'UTR of the bovine MHC-I heavy chain: bta-miR-148b and bta-miR-152. Dual luciferase reporter and miRNA mimic/inhibitor assays suggested that bta-miR-148b/152 were negatively correlated with bovine MHC I heavy chain genes. The function of the MHC-I heavy chain was then investigated using qRT-PCR, ELISA, western blotting, immunofluorescence, and RNA interference assays in primary bEECs and an endometrial epithelial cell line (BEND). The results demonstrated that bta-miR-148b/152 could promote TLR4-triggered inflammatory responses by targeting the bovine MHC-I heavy chain, and the MHC-I molecule negatively regulated TLR4-induced inflammatory reactions may through the Fps-SHP-2 pathway. Our discovery offers novel insight into negative regulation of the TLR4 pathway and elucidates the mechanism by which bovine MHC-I molecules control congenital inflammatory reactions. PMID- 29456543 TI - No Interactions of Stacked Bt Maize with the Non-target Aphid Rhopalosiphum padi and the Spider Mite Tetranychus urticae. AB - In the agroecosystem, genetically engineered plants producing insecticidal Cry proteins from Bacillus thuringiensis (Bt) interact with non-target herbivores and other elements of the food web. Stacked Bt crops expose herbivores to multiple Cry proteins simultaneously. In this study, the direct interactions between SmartStax(r) Bt maize producing six different Cry proteins and two herbivores with different feeding modes were investigated. Feeding on leaves of Bt maize had no effects on development time, fecundity, or longevity of the aphid Rhopalosiphum padi (Hemiptera: Aphididae), and no effects on the egg hatching time, development time, sex ratio, fecundity, and survival of the spider mite Tetranychus urticae (Acari: Tetranychidae). The results thus confirm the lack of effects on those species reported previously for some of the individual Cry proteins. In the Bt maize leaves, herbivore infestation did not result in a consistent change of Cry protein concentrations. However, occasional statistical differences between infested and non-infested leaves were observed for some Cry proteins and experimental repetitions. Overall, the study provides evidence that the Cry proteins in stacked Bt maize do not interact with two common non-target herbivores. PMID- 29456545 TI - The Dangers of Being a Small, Oligotrophic and Light Demanding Freshwater Plant across a Spatial and Historical Eutrophication Gradient in Southern Scandinavia. AB - European freshwater habitats have experienced a severe loss of plant diversity, regionally and locally, over the last century or more. One important and well established driver of change is eutrophication, which has increased with rising population density and agricultural intensification. However, reduced disturbance of lake margins may have played an additional key role. The geographical variation in water chemistry, which has set the scene for - and interacted with - anthropogenic impact, is much less well understood. We took advantage of some recently completed regional plant distribution surveys, relying on hundreds of skilled citizen scientists, and analyzed the hydrophyte richness to environment relations in five contiguous South-Scandinavian regions. For three of the regions, we also assessed changes to the freshwater flora over the latest 50-80 years. We found a considerable variation in background total phosphorus concentrations and alkalinity, both within and between regions. The prevalence of functional groups differed between regions in accordance with the environmental conditions and the species' tolerance to turbid waters. Similarly, the historical changes within regions followed the same trend in correspondence to the altered environmental conditions over time. Small submerged species decreased relative to tall submerged and floating-leaved species along the regional and historical eutrophication gradients. These changes were accompanied by systematically greater relative abundance of species of higher phosphorus prevalence. We conclude that species traits in close correspondence with anthropogenic impacts are the main determinants of local, regional and historical changes of species distribution and occupancy, while pure biogeography plays a minor role. Conservation measures, such as re-oligotrophication and re-established disturbance regimes through grazing and water level fluctuations, may help reduce the tall reed vegetation, restore the former richness of the freshwater flora and safeguard red-listed species, although extended time delays are anticipated in nutrient-rich regions, in which species only survive at minute abundance in isolated refugia. PMID- 29456544 TI - Inheritance of Mesotrione Resistance in an Amaranthus tuberculatus (var. rudis) Population from Nebraska, USA. AB - A population of Amaranthus tuberculatus (var. rudis) evolved resistance to 4 hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor herbicides (mesotrione, tembotrione, and topramezone) in Nebraska. The level of resistance was the highest to mesotrione, and the mechanism of resistance in this population is metabolism-based likely via cytochrome P450 enzymes. The increasing number of weeds resistant to herbicides warrants studies on the ecology and evolutionary factors contributing for resistance evolution, including inheritance of resistance traits. In this study, we investigated the genetic control of mesotrione resistance in an A. tuberculatus population from Nebraska, USA. Results showed that reciprocal crosses in the F1 families exhibited nuclear inheritance, which allows pollen movement carrying herbicide resistance alleles. The mode of inheritance varied from incomplete recessive to incomplete dominance depending upon the F1 family. Observed segregation patterns for the majority of the F2 and back-cross susceptible (BC/S) families did not fit to a single major gene model. Therefore, multiple genes are likely to confer metabolism-based mesotrione resistance in this A. tuberculatus population from Nebraska. The results of this study aid to understand the genetics and inheritance of a non target-site based mesotrione resistant A. tuberculatus population from Nebraska, USA. PMID- 29456546 TI - Genome-Wide Association Studies and Comparison of Models and Cross-Validation Strategies for Genomic Prediction of Quality Traits in Advanced Winter Wheat Breeding Lines. AB - The aim of the this study was to identify SNP markers associated with five important wheat quality traits (grain protein content, Zeleny sedimentation, test weight, thousand-kernel weight, and falling number), and to investigate the predictive abilities of GBLUP and Bayesian Power Lasso models for genomic prediction of these traits. In total, 635 winter wheat lines from two breeding cycles in the Danish plant breeding company Nordic Seed A/S were phenotyped for the quality traits and genotyped for 10,802 SNPs. GWAS were performed using single marker regression and Bayesian Power Lasso models. SNPs with large effects on Zeleny sedimentation were found on chromosome 1B, 1D, and 5D. However, GWAS failed to identify single SNPs with significant effects on the other traits, indicating that these traits were controlled by many QTL with small effects. The predictive abilities of the models for genomic prediction were studied using different cross-validation strategies. Leave-One-Out cross-validations resulted in correlations between observed phenotypes corrected for fixed effects and genomic estimated breeding values of 0.50 for grain protein content, 0.66 for thousand-kernel weight, 0.70 for falling number, 0.71 for test weight, and 0.79 for Zeleny sedimentation. Alternative cross-validations showed that the genetic relationship between lines in training and validation sets had a bigger impact on predictive abilities than the number of lines included in the training set. Using Bayesian Power Lasso instead of GBLUP models, gave similar or slightly higher predictive abilities. Genomic prediction based on all SNPs was more effective than prediction based on few associated SNPs. PMID- 29456547 TI - Evolutionary Origin, Gradual Accumulation and Functional Divergence of Heat Shock Factor Gene Family with Plant Evolution. AB - Plants, as sessile organisms, evolved a complex and functionally diverse heat shock factor (HSF) gene family to cope with various environmental stresses. However, the limited evolution studies of the HSF gene family have hindered our understanding of environmental adaptations in plants. In this study, a comprehensive evolution analysis on the HSF gene family was performed in 51 representative plant species. Our results demonstrated that the HSFB group which lacks a typical AHA activation domain, was the most ancient, and is under stronger purifying selection pressure in the subsequent evolutionary processes. While, dramatic gene expansion and functional divergence occurred at evolution timescales corresponding to plant land inhabit, which contribute to the emergence and diversification of the HSFA and HSFC groups in land plants. During the plant evolution, the ancestral functions of HSFs were maintained by strong purifying pressure that acted on the DNA binding domain, while the variable oligomerization domain and motif organization of HSFs underwent functional divergence and generated novel subfamilies. At the same time, variations were further accumulated with plant evolution, and this resulted in remarkable functional diversification among higher plant lineages, including distinct HSF numbers and selection pressures of several HSF subfamilies between monocots and eudicots, highlighting the fundamental differences in different plant lineages in response to environmental stresses. Taken together, our study provides novel insights into the evolutionary origin, pattern and selection pressure of plant HSFs and delineates critical clues that aid our understanding of the adaptation processes of plants to terrestrial environments. PMID- 29456548 TI - GABA Shunt in Durum Wheat. AB - Plant responses to salinity are complex, especially when combined with other stresses, and involve many changes in gene expression and metabolic fluxes. Until now, plant stress studies have been mainly dealt only with a single stress approach. However, plants exposed to multiple stresses at the same time, a combinatorial approach reflecting real-world scenarios, show tailored responses completely different from the response to the individual stresses, due to the stress-related plasticity of plant genome and to specific metabolic modifications. In this view, recently it has been found that gamma-aminobutyric acid (GABA) but not glycine betaine (GB) is accumulated in durum wheat plants under salinity only when it is combined with high nitrate and high light. In these conditions, plants show lower reactive oxygen species levels and higher photosynthetic efficiency than plants under salinity at low light. This is certainly relevant because the most of drought or salinity studies performed on cereal seedlings have been done in growth chambers under controlled culture conditions and artificial lighting set at low light. However, it is very difficult to interpret these data. To unravel the reason of GABA accumulation and its possible mode of action, in this review, all possible roles for GABA shunt under stress are considered, and an additional mechanism of action triggered by salinity and high light suggested. PMID- 29456549 TI - Global DNA Methylation in the Chestnut Blight Fungus Cryphonectria parasitica and Genome-Wide Changes in DNA Methylation Accompanied with Sectorization. AB - Mutation in CpBck1, an ortholog of the cell wall integrity mitogen-activated protein kinase kinase kinase (MAPKKK) of Saccharomyces cerevisiae, in the chestnut blight fungus Cryphonectria parasitica resulted in a sporadic sectorization as culture proceeded. The progeny from the sectored area maintained the characteristics of the sector, showing a massive morphogenetic change, including robust mycelial growth without differentiation. Epigenetic changes were investigated as the genetic mechanism underlying this sectorization. Quantification of DNA methylation and whole-genome bisulfite sequencing revealed genome-wide DNA methylation of the wild-type at each nucleotide level and changes in DNA methylation of the sectored progeny. Compared to the wild-type, the sectored progeny exhibited marked genome-wide DNA hypomethylation but increased methylation sites. Expression analysis of two DNA methyltransferases, including two representative types of DNA methyltransferase (DNMTase), demonstrated that both were significantly down-regulated in the sectored progeny. However, functional analysis using mutant phenotypes of corresponding DNMTases demonstrated that a mutant of CpDmt1, an ortholog of RID of Neurospora crassa, resulted in the sectored phenotype but the CpDmt2 mutant did not, suggesting that the genetic basis of fungal sectorization is more complex. The present study revealed that a mutation in a signaling pathway component resulted in sectorization accompanied with changes in genome-wide DNA methylation, which suggests that this signal transduction pathway is important for epigenetic control of sectorization via regulation of genes involved in DNA methylation. PMID- 29456550 TI - Genomic Analysis Revealed New Oncogenic Signatures in TP53-Mutant Hepatocellular Carcinoma. AB - The TP53 gene is the most commonly mutated gene in human cancers and mutations in TP53 have been shown to have either gain-of-function or loss-of-function effects. Using the data generated by The Cancer Genome Atlas, we sought to define the spectrum of TP53 mutations in hepatocellular carcinomas (HCCs) and their association with clinicopathologic features, and to determine the oncogenic and mutational signatures in TP53-mutant HCCs. Compared to other cancer types, HCCs harbored distinctive mutation hotspots at V157 and R249, whereas common mutation hotspots in other cancer types, R175 and R273, were extremely rare in HCCs. In terms of clinicopathologic features, in addition to the associations with chronic viral infection and high Edmondson grade, we found that TP53 somatic mutations were less frequent in HCCs with cholestasis or tumor infiltrating lymphocytes, but were more frequent in HCCs displaying necrotic areas. An analysis of the oncogenic signatures based on the genetic alterations found in genes recurrently altered in HCCs identified four distinct TP53-mutant subsets, three of which were defined by CTNNB1 mutations, 1q amplifications or 8q24 amplifications, respectively, that co-occurred with TP53 mutations. We also found that mutational signature 12, a liver cancer-specific signature characterized by T>C substitutions, was prevalent in HCCs with wild-type TP53 or with missense TP53 mutations, but not in HCCs with deleterious TP53 mutations. Finally, whereas patients with HCCs harboring deleterious TP53 mutations had worse overall and disease-free survival than patients with TP53-wild-type HCCs, patients with HCCs harboring missense TP53 mutations did not have worse prognosis. In conclusion, our results highlight the importance to consider the genetic heterogeneity among TP53-mutant HCCs in studies of biomarkers and molecular characterization of HCCs. PMID- 29456551 TI - Genetic Diversity of the Endangered Neotropical Cichlid Fish (Gymnogeophagus setequedas) in Brazil. AB - Gymnogeophagus setequedas is a rare and rheophilic species of tribe Geophagini, considered endangered in Brazilian red lists. Its previously known geographical distribution range was the Parana River basin, in Paraguay, and a tributary of the Itaipu Reservoir in Brazil. Since its description no specimens have been collected in the original known distribution area. However, recent records of G. setequedas in the lower Iguacu River, in a region considered highly endemic for the ichthyofauna, extended the known geographical distribution and may represent one of the last remnants of the species. The aim of this study was to estimate the genetic diversity and population structure of G. setequedas, using microsatellite markers and mitochondrial haplotypes, in order to test the hypothesis of low genetic diversity in this restricted population. Muscular tissue samples of 86 specimens were obtained from nine locations in the Lower Iguacu River basin, between upstream of the Iguacu Falls and downstream of the Salto Caxias Reservoir. Seven microsatellites loci were examined and a total of 120 different alleles were obtained. The number of alleles per locus (NA) was 17.429, effective alleles (NE) 6.644, expected heterozygosity (HE) 0.675, observed (HO) heterozygosity 0.592, and inbreeding coefficient (FIS) 0.128. Twelve haplotypes in the D-Loop region were revealed, with values of h (0.7642) and pi (0.00729), suggesting a large and stable population with a long evolutionary history. Thus, both molecular markers revealed high levels of genetic diversity and indicated the occurrence of a single G. setequedas population distributed along a stretch of approximately 200 km. The pattern of mismatch distribution was multimodal, which is usually ascribed to populations in demographic equilibrium. Nevertheless, the construction of a new hydroelectric power plant, already underway between the Salto Caxias Reservoir and Iguacu Falls, could fragment this population, causing loss of genetic diversity and population decline, and for this reason it is necessary to maintain the Iguacu River tributaries and downstream area from the Lower Iguacu Reservoir free of additional dams, to guarantee the survival of this species. PMID- 29456552 TI - Identification of Single Nucleotide Non-coding Driver Mutations in Cancer. AB - Recent whole-genome sequencing studies have identified millions of somatic variants present in tumor samples. Most of these variants reside in non-coding regions of the genome potentially affecting transcriptional and post transcriptional gene regulation. Although a few hallmark examples of driver mutations in non-coding regions have been reported, the functional role of the vast majority of somatic non-coding variants remains to be determined. This is because the few driver variants in each sample must be distinguished from the thousands of passenger variants and because the logic of regulatory element function has not yet been fully elucidated. Thus, variants prioritized based on mutational burden and location within regulatory elements need to be validated experimentally. This is generally achieved by combining assays that measure physical binding, such as chromatin immunoprecipitation, with those that determine regulatory activity, such as luciferase reporter assays. Here, we present an overview of in silico approaches used to prioritize somatic non-coding variants and the experimental methods used for functional validation and characterization. PMID- 29456554 TI - Compound Heterozygous Variants in the Coiled-Coil Domain Containing 40 Gene in a Chinese Family with Primary Ciliary Dyskinesia Cause Extreme Phenotypic Diversity in Cilia Ultrastructure. AB - Purpose: Primary ciliary dyskinesia (PCD) is a rare genetic disorder manifested with recurrent infections of respiratory tract and infertility. Mutations in more than 20 genes including the Coiled-Coil Domain Containing 40 (CCDC40) gene are associated with PCD. A Chinese proband with a clinical diagnosis of PCD was analyzed for mutations in these genes to identify the genetic basis of the disease in the family. The proband showed altered mucociliary clearance of the airways, various degree of hyperemia and edema of the mucous membrane, left/right body asymmetry, infertility and ultrastructural abnormality of cilia in both sperm and bronchioles. Methods: The DNA from the proband was analyzed for genetic variation in a subset of genes known to cause PCD using targeted next generation sequencing in order to understand the molecular and genetic basis of the PCD in present family. The result of targeted next generation sequencing has been validated by Sanger sequencing and q-PCR. Results: Targeted next-generation sequencing identified two novel mutations (c.1259delA and EX17_20 deletion) in CCDC40 gene that causes abnormal CCDC40 mRNA expression. These two novel variants cause disorganization of axoneme filaments, which resulted in reduction of sperm motility and phenotypic diversity in ultrastructure of cilia in the proband. Conclusion: These findings highlight the significance of the mutations in CCDC40 as novel candidates for genetic testing in PCD patients as well as the key role of ICSI treatment for the families affected by this ciliary dysmotility. Our findings showed that our work enriched the performance of cilia ultrastructure which were not previously reported in PCD patients. PMID- 29456553 TI - Silencing of Iron and Heme-Related Genes Revealed a Paramount Role of Iron in the Physiology of the Hematophagous Vector Rhodnius prolixus. AB - Iron is an essential element for most organisms However, free iron and heme, its complex with protoporphyrin IX, can be extremely cytotoxic, due to the production of reactive oxygen species, eventually leading to oxidative stress. Thus, eukaryotic cells control iron availability by regulating its transport, storage and excretion as well as the biosynthesis and degradation of heme. In the genome of Rhodnius prolixus, the vector of Chagas disease, we identified 36 genes related to iron and heme metabolism We performed a comprehensive analysis of these genes, including identification of homologous genes described in other insect genomes. We observed that blood-meal modulates the expression of ferritin, Iron Responsive protein (IRP), Heme Oxygenase (HO) and the heme exporter Feline Leukemia Virus C Receptor (FLVCR), components of major pathways involved in the regulation of iron and heme metabolism, particularly in the posterior midgut (PM), where an intense release of free heme occurs during the course of digestion. Knockdown of these genes impacted the survival of nymphs and adults, as well as molting, oogenesis and embryogenesis at different rates and time courses. The silencing of FLVCR caused the highest levels of mortality in nymphs and adults and reduced nymph molting. The oogenesis was mildly affected by the diminished expression of all of the genes whereas embryogenesis was dramatically impaired by the knockdown of ferritin expression. Furthermore, an intense production of ROS in the midgut of blood-fed insects occurs when the expression of ferritin, but not HO, was inhibited. In this manner, the degradation of dietary heme inside the enterocytes may represent an oxidative challenge that is counteracted by ferritins, conferring to this protein a major antioxidant role. Taken together these results demonstrate that the regulation of iron and heme metabolism is of paramount importance for R. prolixus physiology and imbalances in the levels of these key proteins after a blood- meal can be extremely deleterious to the insects in their various stages of development. PMID- 29456555 TI - A Bootstrap Based Measure Robust to the Choice of Normalization Methods for Detecting Rhythmic Features in High Dimensional Data. AB - Motivation: Gene-expression data obtained from high throughput technologies are subject to various sources of noise and accordingly the raw data are pre processed before formally analyzed. Normalization of the data is a key pre processing step, since it removes systematic variations across arrays. There are numerous normalization methods available in the literature. Based on our experience, in the context of oscillatory systems, such as cell-cycle, circadian clock, etc., the choice of the normalization method may substantially impact the determination of a gene to be rhythmic. Thus rhythmicity of a gene can purely be an artifact of how the data were normalized. Since the determination of rhythmic genes is an important component of modern toxicological and pharmacological studies, it is important to determine truly rhythmic genes that are robust to the choice of a normalization method. Results: In this paper we introduce a rhythmicity measure and a bootstrap methodology to detect rhythmic genes in an oscillatory system. Although the proposed methodology can be used for any high throughput gene expression data, in this paper we illustrate the proposed methodology using several publicly available circadian clock microarray gene expression datasets. We demonstrate that the choice of normalization method has very little effect on the proposed methodology. Specifically, for any pair of normalization methods considered in this paper, the resulting values of the rhythmicity measure are highly correlated. Thus it suggests that the proposed measure is robust to the choice of a normalization method. Consequently, the rhythmicity of a gene is potentially not a mere artifact of the normalization method used. Lastly, as demonstrated in the paper, the proposed bootstrap methodology can also be used for simulating data for genes participating in an oscillatory system using a reference dataset.

PMID- 29456556 TI - Human Umbilical Cord Wharton Jelly-Derived Adult Mesenchymal Stem Cells, in Biohybrid Scaffolds, for Experimental Skin Regeneration. AB - The ultimate goal for skin tissue engineering is to regenerate skin lesions to allow the full restoration of morphological and functional properties as what they were before injury. To this end, we have assembled a new prototype of a biomimetic human umbilical cord adult mesenchymal stem cell (hUCMS)/fibrin-based scaffold. We have fully characterized the proposed dermal equivalent (DE) in vitro, to assess morphological, functional, and biological properties of the encased cells. We transplanted DE subcutaneously into immunocompetent rodents, to verify its full biocompatibility. Finally, we studied DE graft effects on full thickness wounds, in immunocompetent mice to demonstrate its capability to drive the healing process in the absence of significant scarring tissue. The excellent outcome of these in vivo studies fuels hope that this new approach, based on a biohybrid DE, may be applied to the operative treatment of skin lesions (i.e., diabetic foot ulcers and burns) in man.

AB - Background: Normal size of mesenteric lymph nodes has not been well evaluated, as these lymph nodes are small but may be seen frequently in computed tomography (CT). The aim of this study is to determine the prevalence of mesenteric lymph nodes at root of mesentery and mesentery itself. Materials and Methods: This is a cross-sectional study on traumatic patients with normal multidetector CT (MDCT) referred to Al-Zahra Hospital in 2014-2016. The largest short axis of lymph nodes was recorded. Their location was divided into three groups of mesenteric root, peripheral mesentery, and mesentery of the right lower quadrant (RLQ). Size and number of lymph nodes in terms of locations were recorded. A number of more than 6 nodes in a position was defined as cluster nodes. Data were analyzed using SPSS software version 20. P < 0.05 was considered statistically significant. Results: Four hundred traumatic patients underwent MDCT scanning. The mean age of these patients was 36.6 +/- 13.4 years. The number of lymph nodes was <3 in 49.3%, 52.5%, and 52.2%; 3-6 in 45.8%, 42.8%, and 42.8%; >6 in 5%, 4.8%, and 4.8% of central, peripheral, and RLQ mesentery, respectively. The average size of largest central, peripheral, and RLQ lymph nodes was 4.53 +/- 1.33, 4.37 +/- 1.68, and 4.37 +/- 1.68, respectively (P = 0.64). Largest size of short axis in patients with cluster lymph nodes was significantly more than noncluster nodes (P < 0.001 for all regions). Conclusion: Mean size of mesenteric lymph nodes was similar to the previous study, but the largest nodes were considerably larger. Furthermore, largest short axis of cluster nodes was significantly more than noncluster ones. PMID- 29456557 TI - The altered expression of perineuronal net elements during neural differentiation. AB - Background: Perineuronal nets (PNNs), which are localized around neurons during development, are specialized forms of neural extracellular matrix with neuroprotective and plasticity-regulating roles. Hyaluronan and proteoglycan link protein 1 (HAPLN1), tenascin-R (TNR) and aggrecan (ACAN) are key elements of PNNs. In diseases characterized by neuritogenesis defects, the expression of these proteins is known to be downregulated, suggesting that PNNs may have a role in neural differentiation. Methods: In this study, the mRNA and protein levels of HAPLN1, TNR and ACAN were determined and compared at specific time points of neural differentiation. We used PC12 cells as the in vitro model because they reflect this developmental process. Results: On day 7, the HAPLN1 mRNA level showed a 2.9-fold increase compared to the non-differentiated state. However, the cellular HAPLN1 protein level showed a decrease, indicating that the protein may have roles in neural differentiation, and may be secreted during the early period of differentiation. By contrast, TNR mRNA and protein levels remained unchanged, and the amount of cellular ACAN protein showed a 3.7-fold increase at day 7. These results suggest that ACAN may be secreted after day 7, possibly due to its large amount of post-translational modifications. Conclusions: Our results provide preliminary data on the expression of PNN elements during neural differentiation. Further investigations will be performed on the role of these elements in neurological disease models. PMID- 29456560 TI - The effect of testosterone gel on fertility outcomes in women with a poor response in in vitro fertilization cycles: A pilot randomized clinical trial. AB - Background: In this study, the effect of testosterone gel administration during ovulation induction on the fertility rate was examined in women with a poor ovarian response in in vitro fertilization (IVF) cycles. Materials and Methods: The current study is a single-blinded, randomized clinical trial. Patients who met inclusion (Bologna) criteria were placed in the antagonist cycle group. The patients were randomly divided into two groups each included 25 participants treated with a placebo (lubricant gel, the controls) and testosterone gel (intervention). Fertility outcomes were compared between two study groups. Results: The mean +/- standard deviation (SD) age of intervention (41.04 +/- 3.77) versus control group (39.69 +/- 3.29) was not statistically different. The two studied groups were not statistically different in terms of follicle stimulating hormone; antral follicle count, IVF, anti-Mullerian hormone, and the duration of infertility. The mean +/- SD of oocyte 2.48 +/- 1.64 versus 1.17 +/- 1.27 and embryo 1.60 +/- 1.58 versus 0.39 +/- 0.58 in intervention group was significantly higher than control group (P < 0.01). The rate of pregnancy 16% versus 0% and embryo of quality A-B was significantly higher in intervention group than control (60% versus 17.4%, P < 0.05). Conclusion: The results of the current study showed that the testosterone gel has a significant impact on the fertility rate in women with a poor response in the IVF cycles. Further, randomized clinical trials with larger sample sized are recommended.

All data about pathology-based cancer registration (Cancer diagnosis was based on pathological laboratory, ICD-O2) in Chaharmahal and Bakhtiari in Southwestern Iran in 2010-2014 was used. By dividing the number of registered cases of each cancer in every age group into the total observed cancers in that age group, the observed ratio of each cancer in that age group was calculated. Then, using the proposed coefficients Parkin and age-standardized cancer ratio method, the expected ratios in each age group, were calculated. Results: In 5 years study, 2918 new cases of cancer were recorded. Out of them, 1735 (59.46%) were male. The annual average total occurrence of all cancers in this province was 68.2/100,000 populations. The observed incidence ratios of common cancers, including stomach, breast, colorectal, thyroid, lymph nodes, ovaries, gall bladder, the bladder and the brain, were 0.11, 0.12, 0.09, 0.06, 0.02, 0.03, 0.01, 0.08, and 0.05, respectively. The expected incidence ratios of above-mentioned cancers are 0.11, 0.13, 0.1, 0.06, 0.02, 0.03, 0.01, 0.08, and 0.05, respectively. Based on observed (O) and expected (E) comparison, breast and colorectal cancer had higher incidence than expected ratio. Conclusion: Our results showed that in our area, treatment programs and health plans should focus on cancer registration, especially on common cancers and reevaluate breast and colorectal cancer occurrence. Therefore, the plan for the control and prevention of this cancer must be a high priority for health policymakers.

AB - Background: Due to the high incidence and prevalence of infection in neonatal ward, especially Neonatal Intensive Care Units (NICUs) reported by different studies and the important role of colonization with hospital germs in the development of nosocomial infections, we intended to evaluate the risk of colonization with hospital germs in neonates and its associated risk factors. Materials and Methods: This cross-sectional, descriptive-analytical study was conducted in 2016 in a Teaching Center in Iran. In total, 51 neonates were selected based on the inclusion criteria, and after recording their information in a checklist, samples were taken by swab from outer ear, axilla, and groin for culture. Neonates with negative culture from mentioned regions were enrolled in the study. The swab samples again were taken and sent for culture from mentioned regions in at least 3 days after hospitalization. Culture results from first and second sampling were collected and analyzed statistically. Results: This study was conducted on 51 neonates. The mean gestational age among the neonates ranged from 35.25 (Week) +/- 2.98. 22 girls (43.1%) and 29 boys (56.9%), most of them were born by cesarean. Based on the results of logistic regression, a significant association was found between the occurrence of colonization of hospital flora and the place hospitalization of the newborns (odds ratio (OR): 4.750; 95% confidence interval (CI): 1.26-17.85). Conclusion: This study revealed that the only risk factors of colonization with hospital flora in neonates are the type of delivery and place of hospitalization. Based on findings of the study, it is recommended to focus on efforts in increasing the rate of natural birth as well as improving conditions of infection control in NICUs to reduce the number of incidences of colonization with hospital flora in neonates. PMID- 29456563 TI - Does topical tranexamic acid reduce postcoronary artery bypass graft bleeding? AB - Background: Postoperative bleeding is a common problem in cardiac surgery. We tried to evaluate the effect of topical tranexamic acid (TA) on reducing postoperative bleeding of patients undergoing on-pump coronary artery bypass graft (CABG) surgery. Materials and Methods: One hundred and twenty-six isolated primary CABG patients were included in this clinical trial. They were divided blindly into two groups; Group 1, patients receiving 1 g TA diluted in 100 ml normal saline poured into mediastinal cavity before closing the chest and Group 2, patients receiving 100 ml normal saline at the end of operation. First 24 and 48 h chest tube drainage, hemoglobin decrease and packed RBC transfusion needs were compared. Results: Both groups were the same in baseline characteristics including gender, age, body mass index, ejection fraction, clamp time, bypass time, and operation length. During the first 24 h postoperatively, mean chest tube drainage in intervention group was 567 ml compared to 564 ml in control group (P = 0.89). Mean total chest tube drainage was 780 ml in intervention group and 715 ml in control group (P = 0.27). There was no significant difference in both mean hemoglobin decrease (P = 0.26) and packed RBC transfusion (P = 0.7). Topical application of 1 g TA diluted in 100 ml normal saline does not reduce postoperative bleeding of isolated on-pump CABG surgery. Conclusion: We do not recommend topical usage of 1 g TA diluted in 100 ml normal saline for decreasing blood loss in on-pump CABG patients. PMID- 29456564 TI - Role of granulocyte colony-stimulating factor in human reproduction. AB - As new research reveals, granulocyte colony-stimulating factor (G-CSF) plays an effective role in pregnancy success, considering that it not only affects the embryo implantation and ovarian function but also it promotes endometrial thickening and improves the pathophysiology of endometriosis, which all fundamentally lead to reducing pregnancy loss. In this review, we focus on the role of G-CSF in human reproduction. We summarized its role in ovulation, luteinized unruptured follicle syndrome, poor responders, improving repeated in vitro fertilization failure, endometrial receptivity and treatment of thin endometrium, and recurrent spontaneous abortion. PMID- 29456565 TI - Prevalence of peptic ulcer in Iran: Systematic review and meta-analysis methods. AB - Background: Peptic ulcer is a prevalent problem and symptoms include epigastria pain and heartburn. This study aimed at investigating the prevalence and causes of peptic ulcers in Iran using systematic review and meta-analysis. Materials and Methods: Eleven Iranian papers published from 2002 to 2016 are selected using valid keywords in the SID, Goggle scholar, PubMed and Elsevier databases. Results of studies pooled using random effects model in meta-analysis. The heterogeneity of the sample was checked using Q test and I2 index. Results: Total sample size in this study consist of 1335 individuals with peptic ulcer (121 samples per article). The prevalence of peptic ulcers was estimated 34% (95% CI= 0.25 - 0.43). The prevalence of peptic ulcers was 30% and 60% in woman and man respectively. The highest environmental factor (cigarette) has been addressed in 30% (95% CI= 0.23-0.37) of patients. The prevalence of Helicobacter pylori was estimated in 62% (95% CI= 0.49-0.75) of patients. Conclusion: The results of this study show that prevalence of peptic ulcers in Iran (34%) is higher that worldwide rate (6% to 15%). There was an increasing trend in the prevalence of peptic ulcer over a decade from 2002 to 2016. PMID- 29456566 TI - Is application of Kinesio tape to treat hyperlordosis more effective on abdominal muscles or hamstrings? AB - Background: Hyperlordosis is defined as an abnormal increase in the lumbar arch of >40 degrees . This study compared two taping techniques include abdominal muscles and hamstrings taping for the treatment of lumbar hyperlordosis. Materials and Methods: The randomized clinical trial was performed in Shiraz, Iran, during June and September 2014. Thirty women aged 20-45 years old with at least 40 degrees lumbar lordosis participated. The women were randomized into two groups (n = 15). Abdominal muscles taping was performed for the first group, whereas the other group underwent hamstrings taping with 30% tension. Lumbar lordosis was measured before, immediately after, and 24 h after taping. The two way repeated measures analysis of variance was used to compare the two groups for lumbar lordosis angle. Results: No significant differences were detected between the lumbar lordosis angles before and immediately after taping in the two groups (P > 0.05). However, a significant reduction was observed in lordosis angle in the abdominal group and the hamstring group 24 h after taping relative to before intervention (P < 0.01). Conclusion: Taping of the abdominal and hamstring muscles was not effective immediately, whereas it decreased lordosis after 24 h. PMID- 29456567 TI - Influence of blood glucose level on the prognosis of patients with diabetes mellitus complicated with ischemic stroke. AB - We carried out this meta-analysis for the aim of exploring the influence of diabetes mellitus (DM) on the prognosis of patients with ischemic stroke. Relevant studies were identified using computerized databases supplemented with manual search strategies. The included studies were strictly followed the inclusion and exclusion criteria. Case-control studies which related to the influence of DM on the prognosis of patients with ischemic stroke were selected. Statistical analyses were implemented with the STATA version 12.0 statistical software. Our current meta-analysis initially retrieved 253 studies (227 in Chinese and 26 in English), 13 studies (6 in English and 7 in Chinese) were eventually incorporated in this meta-analysis. These 13 case-control studies included 8463 patients altogether (3249 patients with DM complicated with ischemic stroke and 5214 patients with ischemic stroke). The results of this meta analysis manifested that there was a significant difference of the blood glucose level at 48 h after stroke between patients with DM complicated with ischemic stroke and patients with ischemic stroke (standard mean difference [SMD] =1.27, 95% confidence interval [CI] =0.02-2.51, P = 0.047); however, the effectiveness, fatality, and the National Institutes of Health Stroke Scale (NIHSS) score in patients with DM complicated with ischemic stroke, and patients with ischemic stroke had no significant difference (effectiveness: risk ratio [RR] = 0.88, 95% CI = 0.75-1.03, P = 0.121; fatality: RR = 1.29, 95% CI = 0.97-1.71, P = 0.081; NIHSS score: SMD = -0.14, 95% CI = -1.56-1.28, P = 0.849). The current evidence suggests that there is statistical difference of the blood glucose level at 48 h after stroke between patients with DM complicated with ischemic stroke and patients with ischemic stroke, but there is no statistical difference of prognostic indicators between patients in two groups. Thus, our study provides certain clinical value. PMID- 29456569 TI - Use of Western Medicine and Traditional Korean Medicine for Joint Disorders: A Retrospective Comparative Analysis Based on Korean Nationwide Insurance Data. AB - This study aimed to compare the usage of Western medicine and traditional Korean medicine for treating joint disorders in Korea. Data of claims from all medical institutions with billing statements filed to HIRA from 2011 to 2014 for the four most frequent joint disorders were used for the analysis. Data from a total of 1,100,018 patients who received medical services from 2011 to 2014 were analyzed. Descriptive statistics are presented as type of care and hospital type. All statistical analyses were performed using IBM SPSS for Windows version 21. Of the 1,100,018 patients with joint disorders, 456,642 (41.5%) were males and 643,376 (58.5%) were females. Per diem costs of hospitalization in Western medicine clinics and traditional Korean medicine clinics were approximately 160,000 KRW and 50,000 KRW, respectively. Among costs associated with Western medicine, physiotherapy cost had the largest proportion (28.78%). Among costs associated with traditional Korean medicine, procedural costs and treatment accounted for more than 70%, followed by doctors' fees (21.54%). There were distinct differences in patterns of medical care use and cost of joint disorders at the national level in Korea. This study is expected to contribute to management decisions for musculoskeletal disease involving joint disorders. PMID- 29456570 TI - Use of Chinese Medicine Reduces the Development of Cervical Cancer from Pap Smear Diagnosed Cervical Dysplasia: A Case-Control Study. AB - The Pap test diagnosed cervical dysplasia, which could recover to normal or progress to cervical cancer (CC), is an early stage of cell abnormality before CC. This case-control study analyzed the differences in the risk to develop CC between Chinese medicine (CM) users and nonusers among women who had ever been diagnosed as having cervical dysplasia. A total of 750 CC patients with a cervical dysplasia history were collected between 1998 and 2011 from National Health Insurance Research Database, and controls were women with cervical dysplasia history but did not develop CC. Adjusted odds ratio (aOR) for developing CC was assessed using multivariable logistic regression after adjusting for age, urbanization of residence, and occupation. The proportion of using CM among CC patients was lower than that among CC nonpatients, with an aOR of 0.8. By analyzing the relationship between CC development and the frequency of CM usage, the trend test revealed a significant decreasing trend for developing CC among high-frequency CM users. Moreover, the most frequently used single herb high-frequency was Rheum palmatum (Da-Huang). The usage of CM might be an effective complementary method to prevent uterine cervix from progressing to CC after cervical dysplasia has occurred. PMID- 29456568 TI - Harnessing the immune system in the battle against breast cancer. AB - Breast cancer is the most prevalent malignancy in women and the second most common cause of cancer-related death worldwide. Despite major innovations in early detection and advanced therapeutics, up to 30% of women with node-negative breast cancer and 70% of women with node-positive breast cancer will develop recurrence. The recognition that breast tumors are infiltrated by a complex array of immune cells that influence their development, progression, and metastasis, as well as their responsiveness to systemic therapies has sparked major interest in the development of immunotherapies. In fact, not only the native host immune system can be altered to promote potent antitumor response, but also its components can be manipulated to generate effective therapeutic strategies. We present here a review of the major approaches to immunotherapy in breast cancers, both successes and failures, as well as new therapies on the horizon. PMID- 29456571 TI - Resveratrol Ameliorates Experimental Alcoholic Liver Disease by Modulating Oxidative Stress. AB - The aim of this study was to investigate the hepatoprotective effects of resveratrol in alcoholic liver disease (ALD). Alcohol was administered to healthy female rats starting from 6% (v/v) and gradually increased to 20% (v/v) by the fifth week. After 16 weeks of intervention, liver enzymes (aspartate aminotransferase [AST] and alanine aminotransferase [ALT]) were analyzed using a chemistry analyzer, while hepatic antioxidant enzymes, oxidative stress markers, and caspase 3 activity were assessed using ELISA kits. Furthermore, hepatic CYP2E1 protein levels and mRNA levels of antioxidant and inflammation-related genes were determined using western blotting and RT-PCR, respectively. The results showed that resveratrol significantly attenuated alcohol-induced elevation of liver enzymes and improved hepatic antioxidant enzymes. Resveratrol also attenuated alcohol-induced CYP2E1 increase, oxidative stress, and apoptosis (caspase 3 activity). Moreover, genes associated with oxidative stress and inflammation were regulated by resveratrol supplementation. Taken together, the results suggested that resveratrol alleviated ALD through regulation of oxidative stress, apoptosis, and inflammation, which was mediated at the transcriptional level. The data suggests that resveratrol is a promising natural therapeutic agent against chronic ALD. PMID- 29456573 TI - Pharmacological Effect of Caulophyllum robustum on Collagen-Induced Arthritis and Regulation of Nitric Oxide, NF-kappaB, and Proinflammatory Cytokines In Vivo and In Vitro. AB - Caulophyllum robustum Maxim (C. robustum) has commonly been used as traditional Chinese medicine for the treatment of rheumatic pain and rheumatoid arthritis (RA) in China. This paper first investigated the anti-inflammation effect of C. robustum extraction (CRME) on RAW264.7 cells stimulated by lipopolysaccharide (LPS) and gene expression levels of inflammatory factors. Moreover, we first evaluated the anti-RA effects of CRME using collagen-induced arthritis (CIA) in DBA/1J mice, and the incidence, clinical score, and joint histopathology were evaluated. The levels of IL-1, IL-6, TNF-alpha, and PGE2 inflammatory factors in sera of mice were detected by enzyme-linked immunosorbent assay. The expression of NF-kappaB p65 in the joint was tested by immune histochemical technique. The results showed that, compared with the model group, CRME significantly improved symptoms of the arthritis index, limb swelling, and histological findings by decreasing synovial membrane damage, the extent of inflammatory cell infiltration, and the expansion of capillaries in CIA mice. The results also showed that CRME can reduce the levels of IL-1, IL-6, TNF-alpha, and PGE2 and inhibit the expression of NF-kappaB p65. All these results indicated the anti inflammatory efficacy of CRME as a novel botanical extraction for the treatment of RA.

AB - Mangifera indica (family Anacardiaceae), commonly known as mango, is a pharmacologically, ethnomedically, and phytochemically diverse plant. Various parts of M. indica tree have been used in traditional medicine for the treatment of different ailments, and a number of bioactive phytochemical constituents of M. indica have been reported, namely, polyphenols, terpenes, sterols, carotenoids, vitamins, and amino acids, and so forth. Several studies have proven the pharmacological potential of different parts of mango trees such as leaves, bark, fruit peel and flesh, roots, and flowers as anticancer, anti-inflammatory, antidiabetic, antioxidant, antibacterial, antifungal, anthelmintic, gastroprotective, hepatoprotective, immunomodulatory, antiplasmodial, and antihyperlipemic. In the present review, a comprehensive study on ethnopharmacological applications, pharmacological activities, and bioactive compounds of M. indica has been described. PMID- 29456574 TI - The Root Aqueous Extract of Entada africana Guill. et Perr. (Mimosaceae) Inhibits Implant Growth, Alleviates Dysmenorrhea, and Restores Ovarian Dynamic in a Rat Model of Endometriosis. AB - Entada africana (Mimosaceae) was reported to have analgesic and antioxidant properties. The present study is aimed at investigating the effects of the root aqueous extract of Entada africana (EA) on an experimental model of endometriosis. The study was performed in rats orally treated with EA at doses of 127.5, 255, and 510 mg/kg. Microgynon(r) 30 served as the reference substance. Estradiol valerate and oxytocin were used to induce dysmenorrhea. Endometrial implant levels of catalase and malondialdehyde (MDA) allowed estimating tissue oxidative status. Ovarian dynamic and rat sexual behavior were assessed through histological analysis of ovaries, uterus, and vagina. EA decreased dysmenorrhea at tested doses following a 7-day treatment (p < 0.001). Endometrial implant volume decreased following the three treatment periods (p < 0.05). Catalase activity (p < 0.001) and MDA level (p < 0.01) increased only following a 3-day treatment. EA also increased antral follicles, reduced luteinized unruptured follicle number (p < 0.001), and induced animals to be in the estrus phase. In conclusion, EA prevented the progress of endometriosis, reduced dysmenorrhea, promoted ovarian follicle growth, prevented anovulation, and stimulated the special period of rat sexual desire. These results suggest that Entada africana could be a promising alternative option for the treatment of endometriosis. PMID- 29456576 TI - Editorial. PMID- 29456575 TI - Integrative Approach to Facilitate Fracture Healing: Topical Chinese Herbal Paste with Oral Strontium Ranelate. AB - Strontium ranelate (SrR) is one of the pharmaceutical agents reported to be effective on the promotion of fracture healing. This study aimed to evaluate the integrative effect of the oral SrR with a topical Chinese herbal paste, namely, CDR, on facilitation of bone healing. The in vivo efficacy was evaluated using rats with tibial fracture. They were treated with either CDR topically, or SrR orally, or their combined treatments. The in vivo results illustrated a significant additive effect of CDR on SrR in increasing the yield load of the fractured tibia. The in vitro results showed that neither SrR nor CDR exhibited a cytotoxic effect on UMR106 and bone-marrow stem cell (BMSC), but both of them increased the proliferation of BMSC at low concentrations. The combination of CDR at 200 MUg/mL with SrR at 200 or 400 MUg/ml also showed an additive effect on increasing the ALP activity of BMSC. Both SrR and CDR alone reduced osteoclast formation, and the effective concentration of SrR to inhibit osteoclastogenesis was reduced in the presence of CDR. This integrative approach by combining oral SrR and topical CDR is effective in promoting fracture healing properly due to their additive effects on proosteogenic and antiosteoclastogenic properties. PMID- 29456577 TI - Is ultrasound screening for vasa praevia clinically justified and a financially viable screening test? A literature review. AB - Vasa praevia is an obstetric complication currently not screened for within the United Kingdom, which if undetected prenatally can lead to fetal death when the membranes rupture. Internationally, guidelines are available providing guidance on the best screening policy and management pathways. However, the UK National Screening Committee and Royal College of Obstetricians and Gynaecologists do not support screening due to a lack of evidence. Recent studies explore the ability of ultrasound to detect vasa praevia prenatally in both the general and high-risk populations. Whilst there is no consensus on the 'best' screening strategy, the majority of authors note that targeted screening of the high-risk population is the most achievable and cost-effective strategy. Although not infallible, a standard screening protocol could identify the majority of cases in the high-risk group. Introduction of a screening strategy would affect training needs of professionals within the UK and would have implications on the need to produce guidelines on management and quality assurance. Further research is also needed to define a relevant high-risk population and explore how this would impact on service provision. This review explores the current evidence base for systematic screening and the implications for service. PMID- 29456578 TI - Sonographic parameters for diagnosing fetal head engagement during labour. AB - The purpose of this study was to investigate the diagnostic performance of the head-perineum distance, angle of progression, and the head-symphysis distance as intrapartum ultrasound parameters in the determination of an engaged fetal head. Two hundred and one women in labour underwent both ultrasound and digital vaginal examination in the estimation of fetal head station. The transperineal ultrasound measured head-perineum distance, angle of progression, and head-symphysis distance for values correlating with digital vaginal examination head station. Using station 0 as the minimum level of head engagement, correlating cut-off values for head-perineum distance, angle of progression, and head-symphysis distance were obtained. Receiver operating characteristics were used in determining the diagnostic performance of these cut-off values for the detection of fetal head engagement. With head-perineum distance of 3.6 cm the sensitivity and specificity of sonographic determination of engaged fetal head were 78.7 and 72.3%, respectively. A head-symphysis distance of 2.8 cm also had sensitivity and specificity of 74.5 and 70.8%, respectively, in determining engagement, whilst an angle of progression of 101 degrees was consistent with engagement by digital vaginal examination with 68.1% sensitivity and 68.2% specificity. Ultrasound shows high diagnostic performance in determining engaged fetal head at a head perineum distance of <=3.6 cm, head-symphysis distance of <=2.8 cm, and angle of progression of >= 101 degrees . PMID- 29456579 TI - Splenic cyst as a rare cause of fetal abdominal cystic mass: A multicenter series of nine cases and review of the literature. AB - Introduction: Congenital splenic cysts are a rare cause of abdominal cystic masses in the fetus. We describe nine cases of this condition, the largest reported experience to date. A review of the literature for similar cases was also performed. Methods: Cases of congenital splenic cyst were collected from three prenatal diagnostic centers and from a dedicated website of prenatal diagnosis. Information regarding clinical and sonographic findings was obtained by reviewing ultrasound reports and medical records. An electronic search of the Pubmed/MEDLINE database for similar cases, with subsequent manual cross referencing, was performed and the relevant information from the articles was retrieved. Results: A total of nine cases were added to the currently existing literature of 32 cases. In all but one of our cases, the prenatal detection of the splenic cyst was made in the third trimester, with a median gestational age at diagnosis of 30 weeks (range 22-37). The splenic cyst was confirmed after delivery in all but one case, which was lost to follow up. Postnatal sonographic examinations performed in the remaining eight cases showed that the cyst increased in size in two (25%), was stable in size in one (12%), decreased in size in one (12%), and completely regressed in the other four cases (50%). No complications associated with the cysts were reported in the infants. Conclusions: Congenital splenic cyst appears to be a benign condition with no known risk of perinatal complications. Nevertheless, differential diagnosis with other fetal cystic masses of the left upper abdominal quadrant and postnatal sonographic follow up to monitor the size of the cyst are important issues to be considered in the perinatal management of these cases. PMID- 29456580 TI - The accuracy of ultrasound estimation of fetal weight in comparison to birth weight: A systematic review. AB - Ultrasound estimation of fetal weight is a highly influential factor in antenatal management, guiding both the timing and mode of delivery of a pregnancy. Although substantial research has investigated the most accurate ultrasound formula for calculating estimated fetal weight, current evidence indicates significant error levels. The aim of this systematic review was to identify the most accurate method, whilst identifying sources of inaccuracy in order to facilitate recommendations for future practice. Seven studies met the inclusion criteria and 11 different formulae were assessed; ultrasound calculation of fetal weight was most commonly overestimated. The Hadlock A formula produced the most accurate results, with the lowest levels of random error. Methods incorporating just two measurement parameters were inconsistent, producing large random errors across multiple studies. Key sources of inaccuracy included difficulties obtaining accurate fetal measurements in late gestation; the remainder were operator dependent, including lack of experience and insufficient training and audit. The accuracy of ultrasound estimated fetal weight has improved in the last decade, though a lack of consistency remains evident. National implementation of a rigorous audit programme would likely improve accuracy further, and increase the confidence and clinical value of the method. PMID- 29456582 TI - Assessing the accuracy of ultrasound estimation of gestational age during routine antenatal care in in vitro fertilization (IVF) pregnancies. AB - Introduction: In the UK an accurate gestational age is confirmed by ultrasound measured foetal crown rump length (CRL) at 11 + 2-14 + 1 weeks of gestation. The currently recommended Robinson and Fleming crown rump length reference chart was develop in 1975. Advances in ultrasound technology and standardized crown rump length measurement training could mean this is now out of date. Our study aimed to assess its accuracy in current routine antenatal care. Methods: Retrospective data from 178 IVF pregnancies seen for routine antenatal care at a UK Regional Maternity Unit between 1 January 2006 and 1 January 2016 was retrieved. We compared ultrasound calculated crown rump length gestational age taken at the routine First Trimester Screening Clinic (FTSC) with the 'true' gestational age calculated from the known IVF fertilization date. Results: We identified a systematic overestimation of gestational age by ultrasound using the currently recommended crown rump length reference chart when compared to IVF gestational age. The mean overestimation was 3.0 days (95% CI: 2.7 to 3.4), p < 0.001. A range of alternative ultrasound reference charts also generated a systematic overestimation, ranging from 1.6 to 2.9 days (p < 0.001, for each). Conclusions: The current crown rump length reference chart systematically overestimates gestational age by an average of three days when assessed in IVF pregnancies. A systematic overestimation was also identified in alternative crown rump length reference charts. These differences, although slight, were systematic with implications for the accuracy of gestational age estimation particularly in pregnancies at risk of pre-term delivery or growth restriction. Our findings need confirming in larger, non IVF cohorts and could lead to the need for an updated crown rump length reference chart. PMID- 29456581 TI - Antenatal diagnosis of total anomalous pulmonary venous connection in functional single ventricle hearts: Outcomes over 13-year period. AB - Introduction: A functionally single cardiac ventricle seen on foetal ultrasound scan carries a guarded prognosis. The antenatal diagnosis of anomalous pulmonary venous connection (APVC) remains challenging, if there is no associated structural cardiac abnormality. Antenatally, a combination of complex cardiac anomaly with suspected isomerism should raise the possibility of associated total anomalous pulmonary venous connection (TAPVC). There needs to be a high index of suspicion for TAPVC, in functional single ventricle and suspected isomerism, as this carries a very grim outcome postnatally. We illustrate foetal echocardiographic findings of suspected TAPVC and review outcomes of antenatal versus postnatal diagnosis of TAPVC with functional single ventricle. Methods: We retrospectively reviewed our database over 13 years, focusing on foetal cardiac diagnosis, pregnancy outcomes, management and outcomes of livebirths with diagnosis of TAPVC with functional single ventricle. Results: Thirteen patients were included in the review. For the nine antenatal patients, three pregnancies were terminated and six babies were born alive (four babies had compassionate care, two babies had cardiac surgery). One baby is alive at 8.5 years, after Fontan surgery. For the four postnatal patients, three babies had compassionate care (one alive at age 8.1 years) and one baby had cardiac surgery (died age nine weeks). Ten of the 13 patients have right atrial isomerism. Of these 10 patients, only two are alive. For the three non-isomeric babies, only one baby is still alive. There is heterogeneity of the type of TAPVC diagnosed with no particular group that offered better survival. Conclusion: Antenatal diagnosis of TAPVC, even in the context of functional single ventricle remains challenging. If isomerism is suspected, targeted evaluation of pulmonary venous connection should be done. This combination of cardiac lesion carries a very grim outcome. The ability to make this diagnosis antenatally will add to the information and counselling given to these parents. PMID- 29456583 TI - Fetal adrenal gland biometry and cervical elastography as predictors of preterm birth: A comparative study. AB - Background: Preterm birth is a major health problem in developing and developed countries leading to rising health care costs and long-term neurodevelopmental disability. The study aims to evaluate the role of new quantitative markers, like the elastography of cervix (shear wave speed estimation), fetal adrenal zone enlargement, and corrected fetal adrenal gland volume; in preterm birth prediction and analyze their relative importance. Thus, these markers may be beneficial in early preterm birth detection and prevent the related morbidities. Methods: Thirty pregnant females (from 28 to 37 weeks of gestational age), showing clinical signs and delivery outcome of preterm birth were included in the study with an equal number of not-in-labor antenatal females at >=37 weeks as controls. These patients were categorized as preterm and term groups. Both the groups were subjected to trans-abdominal ultrasonography where cervical length, cervical shear wave speed (dynamic elastography) and fetal adrenal gland parameters were measured. Results: Shear wave speed estimation of the antenatal cervix showed the highest sensitivity and specificity (96.7% and 87% respectively) in the prediction of preterm birth and also showed a strong correlation with fetal adrenal gland enlargement. Fetal adrenal zone enlargement was also shown to be a reliable marker of preterm birth, however, with reduced sensitivity and specificity than shear wave speed. Conclusion: The elastographic advancement and fetal adrenal biometry derived quantitative markers can be used as an objective and standard criterion for accurate prediction of preterm birth. PMID- 29456586 TI - Dietary canolol protects the heart against the deleterious effects induced by the association of rapeseed oil, vitamin E and coenzyme Q10 in the context of a high fat diet. AB - Background: Obesity progressively leads to cardiac failure. Omega-3 polyunsaturated fatty acids (PUFA) have been shown to have cardio-protective effects in numerous pathological situations. It is not known whether rapeseed oil, which contains alpha-linolenic acid (ALA), has a similar protective effect. Omega-3 PUFAs are sensitive to attack by reactive oxygen species (ROS), and lipid peroxidation products could damage cardiac cells. We thus tested whether dietary refined rapeseed oil (RSO) associated with or without different antioxidants (vitamin E, coenzyme Q10 and canolol) is cardio-protective in a situation of abdominal obesity. Methods: Sixty male Wistar rats were subdivided into 5 groups. Each group was fed a specific diet for 11 weeks: a low-fat diet (3% of lipids, C diet) with compositionally-balanced PUFAs; a high-fat diet rich in palm oil (30% of lipids, PS diet); the PS diet in which 40% of lipids were replaced by RSO (R diet); the R diet supplemented with coenzyme Q10 (CoQ10) and vitamin E (RTC diet); and the RTC diet supplemented with canolol (RTCC diet). At the end of the diet period, the rats were sacrificed and the heart was collected and immediately frozen. Fatty acid composition of cardiac phospholipids was then determined. Several features of cardiac function (fibrosis, inflammation, oxidative stress, apoptosis, metabolism, mitochondrial biogenesis) were also estimated. Results: Abdominal obesity reduced cardiac oxidative stress and apoptosis rate by increasing the proportion of arachidonic acid (AA) in membrane phospholipids. Dietary RSO had the same effect, though it normalized the proportion of AA. Adding vitamin E and CoQ10 in the RSO-rich high fat diet had a deleterious effect, increasing fibrosis by increasing angiotensin-2 receptor-1b (Ag2R-1b) mRNA expression. Overexpression of these receptors triggers coronary vasoconstriction, which probably induced ischemia. Canolol supplementation counteracted this deleterious effect by reducing coronary vasoconstriction. Conclusion: Canolol was found to counteract the fibrotic effects of vitamin E + CoQ10 on cardiac fibrosis in the context of a high-fat diet enriched with RSO. This effect occurred through a restoration of cardiac Ag2R-1b mRNA expression and decreased ischemia. PMID- 29456585 TI - Neuroinflammation and neurohormesis in the pathogenesis of Alzheimer's disease and Alzheimer-linked pathologies: modulation by nutritional mushrooms. AB - Human life develops and expands not only in time and space, but also in the retrograde permanent recollection and interweaving of memories. Therefore, individual human identity depends fully on a proper access to the autobiographical memory. Such access is hindered or lost under pathological conditions such as Alzheimer's disease, including recently associated oxidant pathologies, such as ocular neural degeneration occurring in glaucoma or neurosensorial degeneration occurring in Meniere's disease. Oxidative stress and altered antioxidant systems have been suggested to play a role in the aetiology of major neurodegenerative disorders, and altered expression of genes sensing oxidative stress, as well as decreased cellular stress response mechanisms could synergistically contribute to the course of these oxidant disorders. Thus, the theory that low levels of stress can produce protective responses against the pathogenic processes is a frontier area of neurobiological research focal to understanding and developing therapeutic approaches to neurodegenerative disorders. Herein, we discuss cellular mechanisms underlying AD neuroinflammatory pathogenesis that are contributory to Alzheimer's disease. We describe endogenous cellular defence mechanism modulation and neurohormesis as a potentially innovative approach to therapeutics for AD and other neurodegenerative conditions that are associated with mitochondrial dysfunction and neuroinflammation. Particularly, we consider the emerging role of the inflammasome as an important component of the neuroprotective network, as well as the importance of Coriolus and Hericium nutritional mushrooms in redox stress responsive mechanisms and neuroprotection. PMID- 29456587 TI - Dietary diversity and associated factors among children of Orthodox Christian mothers/caregivers during the fasting season in Dejen District, North West Ethiopia. AB - Background: Proper feeding practices during early childhood is fundamental for optimal child growth and development. However, scientific evidences on the determinants of dietary diversity are scanty. Particularly, the impact of fasting on children's dietary diversity is not explored in Ethiopia. The aim of this study was to assess dietary diversity and associated factors among children aged 6-23 months, whose mothers/care-givers were Orthodox Christians during the fasting season (Lent), in Dejen District, North West Ethiopia, 2016. Methods: A community based cross-sectional study was conducted during the fasting season from March to April, 2016. The study sample were children aged 6-23 months, whose mothers/care-givers were Orthodox Christians. A systematic random sampling technique was used to select a sample of 967 children proportionally from all selected kebeles. Data was entered using Epi data and statistical analysis were done using logistic regression. P-value < 0.05 at 95% confidence interval was taken as statistically significant. Results: Only 13.6% of children surveyed met the minimum requirement for dietary diversity. Unsatisfactory exposure to media [AOR = 5.22] and low household monthly income [AOR = 2.20] were negatively associated with dietary diversity. As compared to economic related reasons, mothers/caregivers who do not feed diet of animal origin to their children due to fear of utensil contamination for family food preparation were 1.5 times [AOR=1.5; 95% CI (1.05 - 2.53)] less likely to feed the recommended dietary diversity. Conclusions: The findings of this study revealed that the diet of children in the study area lacked diversity. Promoting mass media and socioeconomic empowerment of women have positive contribution to optimal child feeding practice. Sustained nutrition education to mothers regarding proper infant and young child feeding practice in collaboration with the respective religious leaders is highly recommended. PMID- 29456588 TI - A survey of caregiver burden in those providing informal care for patients with schizophrenia or bipolar disorder with agitation: results from a European study. AB - Background: Agitation is a common feature of bipolar disorder and schizophrenia. Previous research indicates that specific symptoms impact caregiver burden in these conditions, but the impact of agitation on caregiver experience is poorly understood. The aim of this study was to characterise caregiver burden in providers of informal care for patients with bipolar disorder and schizophrenia who experience agitation. Methods: In total, 297 matched patient and caregiver surveys were collected across the UK, Germany and Spain between October 2016 and January 2017. To be eligible, caregivers needed to provide informal care to a patient with a diagnosis of bipolar disorder or schizophrenia with agitation managed in a community setting and participating in the patient survey. The caregiver survey captured information on demographics and their role in managing the patient's agitation. Caregiver burden was assessed using the Involvement Evaluation Questionnaire. Descriptive analysis was conducted. Results: Caregivers provided 38.3 h (SD +/- 40.34) a week of support to the patient with 20% providing 50 h or more. Most caregivers reported that they recognised an episode of agitation all of the time (44%, n = 130) or sometimes (40%, n = 119). Verbal de-escalation techniques (talking (80%, n = 239) and soothing (73%, n = 218) were the most commonly reported strategies used by caregivers during an episode of agitation; 14% (n = 43) reported resorting to physically restraining the patient. Caregivers supervised rescue medication administration regularly (41%, n = 69) or occasionally (49%, n = 82). Mean Involvement Evaluation Questionnaire score was 32.2 (+/- 15.27), equivalent to 28.4 (+/- 13.56) in Germany, 35.6 (+/- 16.55) in Spain and 33.3 (+/- 15.15) in the UK. Involvement Evaluation Questionnaire scores were higher for caregivers who reported hostile (41.7 +/- 17.07) lack of control (40.3 +/- 16.35) and violent (39.5 +/- 16.40) patient behaviours when agitated. Over excitement (31.8 +/- 15.05), restless (32.6 +/- 14.77) and tense (32.9 +/- 15.64) behaviours were associated with a lower Involvement Evaluation Questionnaire score. Conclusions: Caregivers are active participants in the recognition and management of agitation episodes. The substantial burden reported by these caregivers is impacted by factors including the number of hours of care provided, patient behaviours and country. These may be viable targets for effective interventions to reduce caregiver burden. PMID- 29456589 TI - Employment status and changes in working career in relation to asthma: a cross sectional survey. AB - Background: Asthmatics confront inconveniences in working life that make it more difficult to pursue a sustainable career, such as unemployment and work disability. Ways of dealing with these inconveniences may be career changes. More needs to be known about the backgrounds and consequences of career changes among asthmatics, especially their relation to asthma or a change in asthma symptoms. The aim of this study was to compare earlier career changes of adults with asthma who are working full time to those who have drifted away from active working life because of work disability, unemployment or early retirement. The frequency of having changed tasks, work place or occupation, whether the changes had been driven by asthma and furthermore, whether the changes had affected their asthma symptoms were investigated. Methods: In this population-based survey study, all patients with reimbursement rights for asthma aged 20-65 years in the city of Tampere (total population 190,000), Finland (n = 2613) were recruited. The questionnaire was sent in October 2000 and the response rate was 79%. The questionnaire included questions e.g. on changing tasks, work place and occupation, whether these changes were driven by asthma or associated with change of asthma symptoms. The respondents were divided into four groups: working full time, work disability, unemployed and retired due to age. We applied ANOVA with Dunnet's post-test (variances were not equal between the groups) for a continued variable age and Chi-squared tests for categorical variables. Logistic regression models were built using unemployed vs. full-time work or work disability vs. full time work as an outcome variable. A p-value of <.05 was considered statistically significant. Results: Adults with asthma working full time had more often made changes in their career, but not as often driven by asthma as those with current work disability. The reason for changing work place compared to full-time workers (24.9%) was more often mainly or partly due to asthma among those with work disability (47.9%, p < 0.001) and the unemployed (43.3%, p = 0.006). Of those who made career changes because of asthma, a major proportion (over 67%) reported relief in asthma symptoms. Changing tasks (OR 5.8, 95% CI 1.9-18.0, for unemployment vs. full-time work), work place (OR 2.8, 95% CI 1.1-7.0, for work disability vs. full-time work and OR 2.6, 95% CI 1.3-5.4, for unemployment vs. full-time work) or occupation (OR 2.7, 95% CI 1.2-6.0, for unemployment vs. full time work) mainly because of asthma was associated with an elevated risk for undesirable employment status even after adjusting for age, gender, smoking and professional status. Conclusions: Career changes that were made mainly because of asthma were associated with undesirable employment status in this study. However, asthma symptoms were relieved after career changes especially among those who reported asthma to be the reason for the change. In addition to proper treatment and counselling of asthma patients towards applicable area of work or study, it may be beneficial to support early career changes in maintaining sustainable working careers among adults with asthma. PMID- 29456591 TI - Gender, money and professional identity: medical social work and the coming of the British National Health Service. AB - The arrival of the British National Health Service (NHS) in 1948 heralded significant changes for all health workers, but the establishment of a 'free' health service was especially meaningful for the hospital almoners-or medical social workers, as they were starting to be known-who had previously been responsible for the assessment and collection of patient payments. It was on this basis they had gained a foothold in the hospital, capitalising on gendered assumptions of financial understanding and behaviour. Yet what might have caused an identity crisis was embraced. This was a dual strategy of both repositioning the profession in alignment with the planned NHS and of asserting an enhanced professional status by distancing themselves from the handling of payment. It was an episode in the history of this distinctly female profession that speaks to women's historic relationship with money. PMID- 29456590 TI - Delayed initiation of breastfeeding in Bukavu, South Kivu, eastern Democratic Republic of the Congo: a cross-sectional study. AB - Background: Timely initiation of breastfeeding can decrease neonatal mortality. However, about 50% of newborns are not breastfeed within 1 h of birth in the Democratic Republic of Congo. The aim of this study was to identify factors associated with delayed initiation of breastfeeding in an urban and rural area of Bukavu, South Kivu province, Democratic Republic of Congo. Methods: We interviewed 396 mother-newborn pairs (185 in the urban area and 211 in the rural area) between 20 July and 10 October 2016. We used descriptive statistics to demonstrate the prevalence of early initiation of breastfeeding. Variables that showed association with delayed initiation of breastfeeding in the bivariate models were entered in a multivariable logistic model. Results: Overall, the rate of early initiation of breastfeeding was 65.9% (69.7% in the rural area, 61.6% in the rural area). Two hundred and seventy-four (62.9%) mothers (159 in rural area and 115 in urban area) were counselled on early initiation of breastfeeding during prenatal care. Most mothers, 65.2% received counselling by a health professional. On multivariable regression analyses after adjusting for other variables in the model, unmarried mothers [Odds Ratio (OR): 1.5 (95% Confidence Interval (CI): 1.13, 1.95)], cesarean delivery [OR: 2.24 (95% CI: 1.74, 2.88)], no counselling on timely initiation of breastfeeding [OR: 1.71 (95% CI: 1.29, 2.20)] and counselling by a non-health professional [OR: 1.84 (95% CI: 1.08, 3.12)] were associated with delayed initiation of breastfeeding. Conclusion: Systemic changes are needed for women having caesarean births to experience skin to-skin and early initiation. In addition, information, education and communication on the importance of timely initiation of breastfeeding must be supported to improve maternal and infant wellbeing.

The aim of this study was to create a geographic accessibility profile of the Scottish population to emergency departments and intensive care units. Methods: This was a descriptive, geographical analysis of population access to 'intermediate' and 'definitive' critical care services in Scotland. Access was defined by the number of people able to reach services within 45 to 60 min, by road and by helicopter. Access was analysed by health board, rurality and as a country using freely available geographically referenced population data. Results: Ninety-six percent of the population reside within a 45-min drive of the nearest intermediate critical care facility, and 94% of the population live within a 45-min ambulance drive time to the nearest intensive care unit. By helicopter, these figures were 95% and 91%, respectively. Some health boards had no access to definitive critical care services within 45 min via helicopter or road. Very remote small towns and very remote rural areas had poorer access than less remote and rural regions. PMID- 29456596 TI - Bridging the logistical gap between ultrasound enthusiasm and accreditation. AB - Point-of-care ultrasound is increasingly recognised as a valuable adjunct to patient care. Trainees in intensive care medicine are expected to accredit in focused intensive care echocardiography, but the availability of trained mentors and logistical/geographical factors make this difficult within the time constraints required. As a result, many trainees who are enthusiastic about point of-care ultrasound find it difficult to achieve accreditation. We present a secure, web-based, multi-user system which mitigates many of these difficulties and allows for clinical mentorship to take place without geographical barriers, and at a time convenient for the participants. PMID- 29456597 TI - Insertion rates and complications of central lines in the UK population: A pilot study. AB - Background: Central venous catheters are inserted ubiquitously in critical care and have roles in drug administration, fluid management and renal replacement therapy. They are also associated with numerous complications. The true number of central venous catheters inserted per year and the proportion of them associated with complications are unknown in the UK. Methods: We performed a prospective audit at five hospitals, as a feasibility pilot for a larger, nationwide audit. Using a novel secure online data collection platform, developed earlier and adapted for this project, all central venous catheters inserted for patients admitted to the Intensive Care Units were documented at five pilot sites across the UK. Results: A total of 117 data collection forms were submitted. Users found the electronic data collection system easy to use. All data fields were ready for analysis immediately after data input. Out of the 117 central venous catheters, 17 were haemodialysis catheters and five pulmonary artery introducers. Experienced practitioners (at least three years' experience) inserted 85% of the central venous catheters. The site of insertion was the internal jugular vein for 80%, femoral for 12% and subclavian for 8% of central venous catheters. Most central venous catheters were inserted in ICU (49%) or theatres (42%). Ultrasound was used for 109 (93%) of central venous catheter insertions and its use was not associated with fewer complications. In 15 cases venopuncture was attempted more than once (all with ultrasound) and this was associated with significantly increased risk of complications. There were eight immediate complications (6.8%): five related to venopuncture and inability to pass a guidewire, two carotid artery punctures and one associated with significant arrhythmia. Conclusion: This study demonstrates the ease and feasibility of collecting detailed descriptive data on central line insertion and its immediate complications in the UK over two weeks. In our proposed nationwide audit, organisation-level data on local policies and standard operating procedures is required to complete the picture on this important aspect of intensive care practice. PMID- 29456598 TI - 'It's learned on the job and it depends who you're with.' An observational qualitative study of how internal jugular cannulation is taught and learned. AB - Internal jugular cannulation may lead to serious complications. Ultrasound guidance is advocated; however, procedural complications remain a concern. Inconsistent education may be in part responsible for this. This study examined how internal jugular cannulation is taught and learned. An ethnographic approach was used in two acute hospitals. Methods comprised interviews, observations and focus groups. An inductive thematic analysis was undertaken. Three themes were identified: apprenticeship, trust and reciprocity. In apprenticeship, a new form of apprenticeship learning, necessitated by the structure of training is described. In trust the strategies by which trainers assess trainees' competence in order to allow them to gain experience is explored. In reciprocity the beneficial influence of trainees is illustrated. This study demonstrates how high stakes procedures are learned. It provides insights into under-investigated topics such as the use of 'permitted mistakes' to stimulate reflection and the role played by trainees in promoting good practice. PMID- 29456599 TI - Deprivation of liberty and intensive care: an update post Ferreira. AB - The right to liberty and security of the person is protected by Article 5 of the European Convention on Human Rights which has been incorporated into the Human Rights Act 1998. The 2014 Supreme Court judgment in the case commonly known as Cheshire West provided for an 'acid test' to be employed in establishing a deprivation of liberty. This 'acid test' of 'continuous supervision and not free to leave' led to concerns that patients lacking capacity being treated on an Intensive Care Unit could be at risk of a 'deprivation of liberty', if this authority was applicable to this setting. This article revisits the aftermath of Cheshire West before describing the recent legal developments around deprivation of liberty pertaining to intensive care by summarising the recent Ferreira judgments which appear for now to answer the question as to the applicability of Cheshire West in life-saving treatment. PMID- 29456600 TI - Conscientious objection to deceased organ donation by healthcare professionals. AB - In this article, we analyse the potential benefits and disadvantages of permitting healthcare professionals to invoke conscientious objection to deceased organ donation. There is some evidence that permitting doctors and nurses to register objections can ultimately lead to attitudinal change and acceptance of organ donation. However, while there may be grounds for conscientious objection in other cases such as abortion and euthanasia, the life-saving nature of donation and transplantation renders objection in this context more difficult to justify. In general, dialogue between healthcare professionals is a more appropriate solution, and any objections must be justified with a strong rationale in hospitals where such policies are put in place.

PMID- 29456602 TI - Review of management in cardiotoxic overdose and efficacy of delayed intralipid use. AB - We present the case of a 51-year-old woman admitted to our intensive care unit following an intentional overdose of a calcium channel antagonist and a beta blocker. The resultant hypotension was reversed with glucagon, noradrenaline, calcium and high-dose insulin. Despite these interventions, she remained vasoplegic and received a delayed, standard dose of intralipid. Subsequently, the vasoplegia resolved rapidly, and the vasopressor was stopped. Here, we review the management of overdose of calcium channel and beta-adrenergic receptor blockers, concentrating on the pharmacology of lipid emulsion therapy. There remain some unanswered questions about lipid emulsion therapy: treatment with lipid therapy is usually advocated as soon as possible; this case report suggests that it remains efficacious even if its administration were delayed. PMID- 29456603 TI - Successful management of 70% acetic acid ingestion on the intensive care unit: A case report. AB - Acetic acid is an organic acid available in concentrations from 2 to 80%. Whilst lower concentrations of 2-6% are more commonly used as the table top condiment, vinegar, much stronger solutions are regularly used in Eastern Europe as food preservatives and cleaning solutions. Oral ingestion of greater than 12% has been reported to cause haemolysis, renal failure, shock and death. Most reported cases of deliberate or accidental poisoning are from Russia and Eastern Europe in the 1980s, with very little currently in western publications. We present the case of a female patient who attempted suicide by drinking 250 ml of 70% acetic acid. Her widespread gastrointestinal injuries were managed conservatively, and despite suffering extensive upper airway and renal complications, she was successfully decannulated and discharged home after a prolonged intensive care and hospital stay. PMID- 29456604 TI - Death from Kratom toxicity and the possible role of intralipid. AB - We present the case of a 26-year-old man who was brought into our emergency department in cardiorespiratory arrest, having taken Kratom 24 h previously. Despite multi-organ support, he deteriorated and died from cardiorespiratory failure and hypoxic brain damage 12 h later. Lipid emulsion was given, with significant temporary improvement in the cardiorespiratory failure. Kratom is derived from Mitragyna speciosa, a tropical deciduous and evergreen tree in the coffee family, and is native to Southeast Asia, and its leaves are used as a legal high in some parts of the world. Here, we review the pharmacochemistry of the drug, and wish to highlight that the effects of Kratom may not be as benign as are commonly reported, and the possible role of intralipid in managing the Kratom toxicity in this case.

We present the case of a 21 year-old male following a witnessed out-of-hospital cardiac arrest who received high-quality cardiopulmonary resuscitation and standard advanced life support for refractory ventricular fibrillation until return of spontaneous circulation after 70 min. Early post-admission echocardiography revealed severe diffuse sub-basal left ventricular hypertrophy with dynamic mid-cavity obstruction and akinetic apical pouching. Within this context, a decatecholaminised strategy comprising a beta-blocker was used to augment the left ventricular end-diastolic volume and attain cardiovascular stability.

AB - The 2016 presidential election season and subsequent political events have had physical and emotional impacts on youth. We collected qualitative insights from 14 to 24 year olds across the US related to these events over time. Open-ended probes were sent via text message at three time points before and after the 2016 presidential election. The majority of youth reported emotional stress during all three time points, and female participants were significantly more likely to experience emotional responses. White participants were more likely to report negative symptoms than their peers both pre-election and at 4-months post election. While preliminary, the results indicate that feelings of stress, anxiety, and fear have persisted in the months following the election, particularly for young women. Additional research is needed to examine the long term effects of political events on the emotional and physical health of youth. PMID- 29456616 TI - The mortality-incidence ratio as an indicator of five-year cancer survival in metropolitan Lima. AB - Introduction: The Mortality-Incidence Ratio complement [1 - MIR] is an indicator validated in various populations to estimate five-year cancer survival, but its validity remains unreported in Peru. This study aims to determine if the MIR correlates directly with five-year survival in patients diagnosed with the ten most common types of cancer in metropolitan Lima. Materials and methods: The Metropolitan Lima Cancer Registry (RCLM in Spanish) for 2004-2005 was used to determine the number of new cases and the number of deaths of the following cancers: breast, stomach, prostate, thyroid, lung, colon, cervical, and liver cancers, as well as non-Hodgkin's lymphoma and leukaemia. To determine the five year survival, the five-year vital status of cases recorded was verified in the National Registry of Identification and Civil Status (RENIEC in Spanish). A linear regression model was used to assess the correlation between [1 - MIR] and total observed five-year survival for the selected cancers. Results: Observed and estimated five-year survival determined by [1 - MIR] for each neoplasia were thyroid (66.7%, 86.7%), breast (69.6%; 68%), prostate (64.3%, 63.8%) and cervical (50.1%, 58.5%), respectively. Pearson's r coefficient for the correlation between [MIR - 1] and observed survival was = 0.9839. Using the coefficient of determination, it was found that [1 - MIR] (X) captures the 96.82% of observed survival (Y). Conclusion: The Mortality-Incidence Ratio complement [1 - MIR] is an appropriate tool for approximating observed five-year survival for the ten types of cancers studied. This study demonstrates the validity of this model for predicting five-year survival in cancer patients in metropolitan Lima. PMID- 29456617 TI - Solitary breast neurofibroma: imaging aspects. AB - Neurofibromas are benign peripheral nerve sheath tumours, which are usually solitary and sporadic. Solitary neurofibromas of the breast are rare. The most common location of a breast neurofibroma is the nipple-areola complex. We report a rare case of a 56-year-old woman with a solitary neurofibroma of the right breast sulcus. PMID- 29456618 TI - An unusual presentation of adult T-cell leukemia/lymphoma. AB - Adult T-cell Leukemia/Lymphoma (ATL) is a rare disease, related to human T lymphotropic virus-1 (HTLV-1) and presented mainly in adulthood by generalised lymphadenopathy, hepatosplenomegaly, skin lesions and hypercalcaemia, with rare gastrointestinal and/or oral manifestations. We reported this case to raise awareness and demonstrate the therapeutic challenges of this rare disease. A 49 year-old Japanese female presented with skin papules on both forearms, painful mouth ulcers and multiple neck swellings since early February 2017. Initial clinical examination and laboratory investigations were misleading and her condition was diagnosed as candidiasis. Because of un-improvement of the case, a screening upper endoscopy was requested 2 months later and revealed characteristic oropharyngeal ulcers which were biopsied, and its pathologic examination confirmed smouldering type ATL. This case report should raise awareness of doctors and endoscopists about this disease especially in HTLV-1 endemic areas to avoid late diagnosis and help achieve earlier therapeutic decisions.

However, the relationship between the two is more complex than just two prevalent conditions co-existing. This review systematically explores the literature around the interplay between the two conditions. It covers the impact of pre-existing T2DM on PCa incidence, grade and stage, as well as exploring the impact of T2DM on PCa outcomes and mortality and the interaction between T2DM and PCa treatments. PMID- 29456621 TI - Men seeking counselling in a Breast Cancer Risk Evaluation Clinic. AB - Background: Hereditary breast and ovary cancer syndrome affects both genders but little is known about the uptake of genetic services by men. The objective of this study is to characterise the male population counselled through a multidisciplinary breast/ovarian program. Methods: Descriptive analysis of male patients counselled from January 2000 to December 2015. Data in this analysis include new cancer diagnoses during prospective follow up. Results: From 4,320 families registered, 362 male patients were identified: 236 (65.2%) from hereditary cancer families (HCF) and 126 (34.8%) from non-HCF. In HCF, 121 patients (51.3%) were mutation carriers (MC): BRCA2 - 102 (84.3%), BRCA1 - 16 (13.2%), CHEK2 - 1 (0.8%) and TP53 - 2 (1.7%). Non-HCF included 126 patients: 85 (67.5%) belonged to families without pathogenic mutations or with variants of unknown clinical significance; 22 (17.5%) refused testing after counselling and 19 (15.0%) did not meet criteria for testing. Both HCF and non-HCF included patients with previous cancer diagnoses: HCF- Breast Cancer (BC) - 18; prostate cancer (PC) - 13; melanoma - 1; others - 7) and non-HCF (BC - 77; PC - 20; gastric cancer (GC) - 1; melanoma - 8; bladder cancer - 1; others - 22). From the 121 MC identified (including the TP53 and CHEK2 carriers), 97 patients (80.2%) adhered to prospective surveillance. With a median follow-up of 36.9 months, 17 cancers were diagnosed in 14 patients, PC being the most frequently diagnosed neoplasia (5 cases). Eleven patients (78.6%) are alive and three patients died of advanced cancer (2 with GC, 1 with disseminated adenocarcinoma). Conclusion: We observed a high adherence to counselling, genetic testing and active surveillance by men belonging to hereditary BC families. Male carriers of pathogenic DNA variants are at risk for several cancers and should be included in prospective follow-up studies. PMID- 29456622 TI - Does the oncology community have a rejection bias when it comes to repurposed drugs? AB - Among the various measures proposed to combat the challenge of financial toxicity in cancer care, an important strategy is the use of lower-priced drugs instead of expensive alternatives. However, the oncology community seems to either ignore or more readily reject cheaper drugs in cancer care compared to more expensive alternatives. In this commentary, we present three examples of lower-priced drugs rejected or ignored by the oncology community and contrast this with three expensive drugs where persistent optimism remained despite negative clinical trial results. We argue that all drugs be held to the same rigorous standards - this not only includes skepticism in the absence of sound evidence, but also the suspension of premature judgement as has happened in the cases of repurposed drugs.

AB - Endometriosis is a fascinating disease that we strive to better understand. Molecular techniques are shedding new light on many important aspects of this disease: from pathogenesis to the recognition of distinct disease variants like deep infiltrating endometriosis. The observation that endometriosis is a cancer precursor has now been strengthened with the knowledge that mutations that are present in endometriosis-associated cancers can be found in adjacent endometriosis lesions. Recent genomic studies, placed in context, suggest that deep infiltrating endometriosis may represent a benign neoplasm that invades locally but rarely metastasises. Further research will help elucidate distinct aberrations which result in this phenotype. With respect to identifying those patients who may be at risk of developing endometriosis-associated cancers, a combination of molecular, pathological, and inheritance markers may define a high risk group that might benefit from risk-reducing strategies. PMID- 29456623 TI - Osteonecrosis of the jaw (ONJ) in patients who receive Bone Targeting Agents (BTAs): the power of e-learning. AB - The definition, pathobiology and risk factors of ONJ in cancer patients who receive BTAs are discussed in the recent ecancer module for osteonecrosis of the jaw (http://ecancer.org/education/module/276-osteonecrosis-of-the-jaw.php). ONJ prevention, early diagnosis and management are presented. The critical question of the performance of dental extraction, during BTA therapy, as indicated with the recent studies, is supported. The importance of the collaboration between dental and oncology professionals and the patients is highlighted and can be achieved through appropriate education. The ecancer modules are valuable tools for successful e-learning in medical oncology education, including ONJ. PMID- 29456624 TI - The case for a regional approach to publication impact. AB - Healthcare-related research is largely regional. Put simply, this is because disease burdens differ between world regions. Even global burdens, such as ischaemic heart disease and cancer, display distinctive characteristics in certain regions that are not seen in others. Regional differences in infrastructure, resources and human capital further compound the differences seen, as they affect the way in which the local scientific community can interact with the local disease burden. As such, it seems fair to assume that healthcare related research ought to be regionally distributed. Although translation of research between regions can sometimes be done, the larger the gap in infrastructure, resources or human capital between regions, the less likely it is that it can be adequately bridged. A recent example of this pertains to accepted life-saving treatment for sepsis in high-income settings, which had the opposite effect when implemented and evaluated in low-income Zambia. This regionality of clinical medicine is, however, not reflected in academic publishing; the impact of a journal is measured and understood by metrics that use the world as their denominator. Therefore, top medical journals are perceived to be relevant equally to all contexts and regions. However, there is a strong case to be made that this lack of granularity is deleterious, and that the creation of a regional impact metric would place clinicians, researchers, and libraries in a better position to understand which journals are relevant to their context and practice. PMID- 29456626 TI - Molybdenum anode: a novel electrode for enhanced power generation in microbial fuel cells, identified via extensive screening of metal electrodes. AB - Background: Metals are considered a suitable anode material for microbial fuel cells (MFCs) because of their high electrical conductivity. However, only a few types of metals have been used as anodes, and an extensive screening of metals has not yet been conducted. In this study, to develop a new metal anode for increased electricity generation in MFCs, 14 different metals (Al, Ti, Fe, Ni, Cu, Zn, Zr, Nb, Mo, Ag, In, Sn, Ta, and W) and 31 of their oxidized forms were comprehensively tested. Oxidized-metal anodes were prepared using flame oxidation, heat treatment, and electrochemical oxidation. The selected anodes were further evaluated in detail using air-cathode single-chambered MFCs. Results: The untreated Mo and electrochemically oxidized Mo anodes showed high averages of maximum power densities in the screening test, followed by flame oxidized (FO) W, FO-Fe, FO-Mo, and Sn-based anodes. The untreated Mo and FO-W anodes were selected for further evaluation. X-ray analyses revealed that the surface of the Mo anode was naturally oxidized in the presence of air, forming a layer of MoO3, a known oxidation catalyst. A high maximum power density (1296 mW/m2) was achieved using the Mo anode in the MFCs, which was superior to that obtained using the FO-W anode (1036 mW/m2). The Mo anode, but not the FO-W anode, continued to produce current without detectable corrosion until the end of operation (350 days). Geobacter was abundant in both biofilms on the Mo and FO-W anodes, as analyzed by high-throughput sequencing of the 16S rRNA gene. Conclusions: The screening test revealed that Mo, W, Fe, and Sn are useful MFC anode materials. The detailed analyses demonstrated that the Mo anode is a high performance electrode with structural simplicity and long-term stability in MFCs. The anode can be easily prepared by merely shaping Mo materials to the desired forms. These properties would enable the large-scale preparation of the anode, required for practical MFC applications. This study also implies the potential involvement of Geobacter in the Mo and W cycles on Earth. PMID- 29456625 TI - Alignment of microbial fitness with engineered product formation: obligatory coupling between acetate production and photoautotrophic growth. AB - Background: Microbial bioengineering has the potential to become a key contributor to the future development of human society by providing sustainable, novel, and cost-effective production pipelines. However, the sustained productivity of genetically engineered strains is often a challenge, as spontaneous non-producing mutants tend to grow faster and take over the population. Novel strategies to prevent this issue of strain instability are urgently needed. Results: In this study, we propose a novel strategy applicable to all microbial production systems for which a genome-scale metabolic model is available that aligns the production of native metabolites to the formation of biomass. Based on well-established constraint-based analysis techniques such as OptKnock and FVA, we developed an in silico pipeline-FRUITS-that specifically 'Finds Reactions Usable in Tapping Side-products'. It analyses a metabolic network to identify compounds produced in anabolism that are suitable to be coupled to growth by deletion of their re-utilization pathway(s), and computes their respective biomass and product formation rates. When applied to Synechocystis sp. PCC6803, a model cyanobacterium explored for sustainable bioproduction, a total of nine target metabolites were identified. We tested our approach for one of these compounds, acetate, which is used in a wide range of industrial applications. The model-guided engineered strain shows an obligatory coupling between acetate production and photoautotrophic growth as predicted. Furthermore, the stability of acetate productivity in this strain was confirmed by performing prolonged turbidostat cultivations. Conclusions: This work demonstrates a novel approach to stabilize the production of target compounds in cyanobacteria that culminated in the first report of a photoautotrophic growth coupled cell factory. The method developed is generic and can easily be extended to any other modeled microbial production system. PMID- 29456627 TI - Growth and lipid accumulation by different nutrients in the microalga Chlamydomonas reinhardtii. AB - Background: Individual nutrient depletion is widely used to induce lipid accumulation in microalgae, which also causes cell growth inhibition and decreases the total biomass. Thus, improving the lipid accumulation without biomass loss in the nutrient deficiency cells becomes a potential cost-effective treatment for cheaper biofuels. Methods: In this study, the effects of different nutritional conditions on the growth and contents of lipids in Chlamydomonas reinhardtii were compared, and the metabolic profiles under different nutritional conditions were also investigated. Results: We showed that similar to other microalgae, nitrogen or phosphorus deficiency inhibited the growth of Chlamydomonas and combined nutrition deficiency reduced biomass by up to 31.7%, though lipid contents in cells (g/g dry weight [DW]) were significantly increased. The addition of sodium acetate countered this growth inhibition that resulted from nitrogen and phosphorus deficiency, with significantly increased biomass. Furthermore, the combination of 4 g/L sodium acetate supplementation with nitrogen and phosphorous deficiency increased total fatty acid yield (mg/L) by 93.0 and 150.1% compared to nutrient-depleted and normal culture conditions, respectively. Metabolite content was affected by the different nutritional conditions, especially metabolites that are involved in lipid metabolism, amino acid metabolism and metabolism of external substances. Conclusion: Further research into these metabolites could shed light onto the relationship between cell growth inhibition and fatty acid accumulation in Chlamydomonas. PMID- 29456628 TI - Identification of influential observations in high-dimensional cancer survival data through the rank product test. AB - Background: Survival analysis is a statistical technique widely used in many fields of science, in particular in the medical area, and which studies the time until an event of interest occurs. Outlier detection in this context has gained great importance due to the fact that the identification of long or short-term survivors may lead to the detection of new prognostic factors. However, the results obtained using different outlier detection methods and residuals are seldom the same and are strongly dependent of the specific Cox proportional hazards model selected. In particular, when the inherent data have a high number of covariates, dimensionality reduction becomes a key challenge, usually addressed through regularized optimization, e.g. using Lasso, Ridge or Elastic Net regression. In the case of transcriptomics studies, this is an ubiquitous problem, since each observation has a very high number of associated covariates (genes). Results: In order to solve this issue, we propose to use the Rank Product test, a non-parametric technique, as a method to identify discrepant observations independently of the selection method and deviance considered. An example based on the The Cancer Genome Atlas (TCGA) ovarian cancer dataset is presented, where the covariates are patients' gene expressions. Three sub-models were considered, and, for each one, different outliers were obtained. Additionally, a resampling strategy was conducted to demonstrate the methods' consistency and robustness. The Rank Product worked as a consensus method to identify observations that can be influential under survival models, thus potential outliers in the high-dimensional space. Conclusions: The proposed technique allows us to combine the different results obtained by each sub-model and find which observations are systematically ranked as putative outliers to be explored further from a clinical point of view. PMID- 29456629 TI - Acute vitamin C improves cardiac function, not exercise capacity, in adults with type 2 diabetes. AB - Background: People with type 2 diabetes (T2D) have impaired exercise capacity, even in the absence of complications, which is predictive of their increased cardiovascular mortality. Cardiovascular dysfunction is one potential cause of this exercise defect. Acute infusion of vitamin C has been separately shown to improve diastolic and endothelial function in prior studies. We hypothesized that acute vitamin C infusion would improve exercise capacity and that these improvements would be associated with improved cardiovascular function. Methods: Adults with T2D (n = 31, 7 female, 24 male, body mass index (BMI): 31.5 +/- 0.8 kg/m2) and BMI-similar healthy adults (n = 21, 11 female, 10 male, BMI: 30.4 +/- 0.7 kg/m2) completed two randomly ordered visits: IV infusion of vitamin C (7.5 g) and a volume-matched saline infusion. During each visit peak oxygen uptake (VO2peak), brachial artery flow mediated dilation (FMD), reactive hyperemia (RH; plethysmography), and cardiac echocardiography were measured. General linear mixed models were utilized to assess the differences in all study variables. Results: Acute vitamin C infusion improved diastolic function, assessed by lateral and septal E:E' (P < 0.01), but did not change RH (P = 0.92), or VO2peak (P = 0.33) in any participants. Conclusion: Acute vitamin C infusion improved diastolic function but did not change FMD, forearm reactive hyperemia, or peak exercise capacity. Future studies should further clarify the role of endothelial function as well as other possible physiological causes of exercise impairment in order to provide potential therapeutic targets.Trial registration NCT00786019. Prospectively registered May 2008. PMID- 29456631 TI - A model of anterior cruciate ligament injury in cynomolgus monkeys developed via arthroscopic surgery. AB - The anterior cruciate ligament (ACL) is an important structure that maintains the stability of knee joints. Animal models of ACL injury are helpful to explore its underlying mechanisms, and strategies for prevention, treatment and rehabilitation. Therefore, the aim of the present study was to develop an efficient model of ACL injury in cynomolgus monkeys via arthroscopic techniques. In the present study, 18 cynomolgus monkeys were randomly divided into a model group (n=6), a sham operation group (n=6) and a blank control group (n=6). One quarter of the ACL was removed under arthroscopy in the model group. In the sham operation group, only arthroscopic exploration was performed as a control. In the blank control group, monkeys were housed under the same conditions for the same length of time. Magnetic resonance imaging examination was performed pre- and post-operatively, as well as measurements of the circumference of the thigh and calf, and of the maximum flexion degree of the knee. Anterior drawer test, Lachman test and pivot-shift tests were also performed. The results revealed that the injured side of the knees in the model group became unstable, as determined from evaluation of the physical tests. In conclusion, based on these findings, the modeling method of ACL injury was effective, and may contribute to the associated research concerning ACL injury. PMID- 29456632 TI - Arrhythmogenic cardiomyopathy: Identification of desmosomal gene variations and desmosomal protein expression in variation carriers. AB - Arrhythmogenic cardiomyopathy (AC) is an inherited disorder that is predominantly present in the right ventricular myocardium. Mutations in the genes encoding the desmosomal protein are thought to underlie the pathogenesis of AC. Since AC is genetically heterogeneous and phenotypically diverse, modifier genes and environmental factors have an important role in disease expression. The aim of the present study was to identify AC-associated desmosomal gene variations, and examine the expression levels of intercalated disc proteins in AC patients who carry the variations (DSG2 p.Leu797Gln, PKP2 p.Ser249Thr and p.E808fsX30). The results of the present investigation provided information on the search for modifier genes and desmosomal gene mutations, and improved our understanding of the mechanism underlying these AC mutations. Genetic screening of five desmosomal genes (DSG2, DSC2, JUP, PKP2, and DSP) in 23 patients with AC who underwent heart transplantation was performed and the expression levels and localizations of intercalated disc proteins were assessed using western blotting and immunohistochemistry, respectively. The results enabled the identification of three desmosomal gene variations (DSG2 L797Q, PKP2 S249T, and E808fsX30), two of which are reported for the first time. DSG2 L797Q was identified in one patient. The protein expression levels of DSG2 in the L797Q carrier were unchanged compared with the healthy controls, and the expression levels of the other proteins (JUP and Cx43) in the intercalated disc were also similar between the healthy controls, the variation carrier and the case controls. Two variations (S249T and E808fsX30) in PKP2 were identified in one patient, the protein expression levels of PKP2 in this patient were significantly decreased, and the expression levels of the other proteins in the intercalated disc was also decreased. The data suggest that there may be modifier genes and other AC associated mutations requiring identification, in order to further our understanding of the disease mechanism induced by these mutations. PMID- 29456630 TI - Roles of Eph/ephrin bidirectional signaling in central nervous system injury and recovery. AB - Multiple cellular components are involved in the complex pathological process following central nervous system (CNS) injury, including neurons, glial cells and endothelial cells. Previous studies and neurotherapeutic clinical trials have assessed the molecular mechanisms that underlie neuronal cell death following CNS injury. However, this approach has largely failed to reduce CNS damage or improve the functional recovery of patients. Erythropoietin-producing human hepatocellular (Eph) receptors and ephrin ligands have attracted considerable attention since their discovery, due to their extensive distribution and unique bidirectional signaling between astrocytes and neurons. Previous studies have investigated the roles of Eph/ephrin bidirectional signaling in the developing central nervous system. It was determined that Eph/ephrin bidirectional signaling is expressed in various CNS regions and cell types, and that it serves diverse roles in the adult CNS. In the present review, the roles of Eph/ephrin bidirectional signaling in CNS injuries are assessed. PMID- 29456633 TI - Crosstalk between apoptosis and autophagy in prostate epithelial cells under androgen deprivation. AB - The present study investigated the molecular mechanism of apoptosis and autophagy in prostate epithelial cells under androgen deprivation (AD). BPH-1 cells were divided into four groups as follows: Control (Cont), AD, autophagy inhibition (AI) and AD + AI groups. Cells in the four groups were treated accordingly, and the level of apoptosis was subsequently measured via flow cytometry. The expression of the microtubule-associated proteins 1A/1B light chain 3 (LC3), caspase-3, poly (ADP-ribose) polymerase 1 (PARP-1) and Beclin-1 proteins of BPH-1 cells was detected at different time points following culture in androgen deprived medium. Western blotting revealed that the basal levels of the LC3-II protein were detected at 0 h. At 4 h, LC3-II was significantly increased compared with 0 h (P<0.05). Beginning at 20 h, the expression level of the LC3-II protein decreased significantly (P<0.05). Western blotting revealed that beginning at 24 h, the expression level of the PARP-1 protein decreased significantly (P<0.001) and the cleavage fragments of the PARP-1 protein appeared. These results further imply that autophagy serves a cell protective function by mutual inhibition with apoptosis in BPH-1 cells in the removal of androgen conditions. Furthermore, the fragments of the cleaved Beclin-1 protein appeared as 35 and 37 kDa bands. Flow cytometry analysis demonstrated that the rate of cell apoptosis in the AD, AI and AD + AI groups was significantly increased compared with the Cont group (P<0.01). Compared with the AD or the AI groups individually, the rate of cell apoptosis in the AD + AI group was significantly increased (P<0.001). These findings suggest that in the early stage of AD, autophagy has a compensatory function in the cell, whereas in the whole process, autophagy and apoptosis share a mutual antagonism. The Beclin-1-C protein fragment contributed positive feedback to the process of apoptosis, which may be a potential mechanism of AD therapy. Therefore, AD and AI exhibit a synergistic effect to further improve the level of apoptosis. PMID- 29456634 TI - Limethason reduces airway inflammation in a murine model of ovalbumin-induced chronic asthma without causing side effects. AB - Airway inflammation is the major pathological feature of asthma. Thus, the current therapeutic strategy for asthma is to control inflammation. Limethason, an anti-inflammation drug, is widely used in rheumatoid arthritis treatment. The aim of the present study was to detect the anti-inflammatory effect and side effects of limethason on airways that were sensitized with ovalbumin in a murine model of chronic asthma. In the present study, BALB/c mice were sensitized with ovalbumin. Airway hyperresponsiveness was estimated, and hematoxylin and eosin staining, Periodic acid-Schiff staining and bronchoalveolar lavage were used to detect the effect on chronic asthma. Limethason effectively reduced airway hyperresponsiveness, and inhibited inflammatory cell infiltration and mucus secretion. Bronchoalveolar lavage fluid analysis revealed that limethason suppressed levels of airway eosinophils. In the period of treatment, limethason exhibited no influence on morphology of the femoral head, bone mineral content or bone mineral density, which were detected by histological studies and dual-energy X-ray absorptiometry. The index of liver, spleen, kidney, gastrocnemius and brown adipose tissue also demonstrated that limethason had no adverse effects on organs and tissues. The present study revealed that limethason could effectively reduce inflammation in an asthma mouse model without side effects. Therefore, limethason may have therapeutic potential for treating chronic asthma clinically. PMID- 29456635 TI - Clinical effect of platelet-rich fibrin on the preservation of the alveolar ridge following tooth extraction. AB - The aim of the present study was to evaluate the clinical efficacy of platelet rich fibrin (PRF) in preserving the alveolar ridge following human tooth extraction. A total of 28 patients were divided into two groups: The experimental and control groups (n=14 each). Following tooth extraction, the experimental group was implanted with PRF membrane, whereas the control group was not. The gingival healing effect was assessed at 7 days, 1 and 3 months later. Cone-beam computed tomography was performed immediately and at 3 months following tooth extraction. The changes in alveolar ridge height, width, and bone mineral density were compared between the two groups. The alveolar bone was removed using the ring drill during the implant surgery at 3 months following tooth extraction. Histomorphometric evaluation was performed to compare new bone formation between groups. The patients in the experimental group reportedly felt better compared with the patients in the control group. The healing of gingival tissue was better in the experimental group than in the control group. A significantly greater novel bone area was observed in the PRF group compared with the control group (P<0.01). However, no statistically significant differences were observed in the mean value of buccal alveolar ridge height, lingual/palatal alveolar ridge height and alveolar ridge width between the two groups. These results suggested that PRF was advantageous in human alveolar ridge preservation with ease of use and simple handling. Histological analysis of novel bone formation confirmed that PRF increased the quality of the novel bone and enhanced the rate of bone formation, despite the effect of PRF was not significant to reduce alveolar bone resorption in the extraction socket alone. PMID- 29456636 TI - Expression of diaphragmatic myostatin and correlation with apoptosis in rats with chronic obstructive pulmonary disease. AB - Chronic obstructive pulmonary disease (COPD) is characterized by progressive airflow limitation and loss of lung function. The present study aimed to investigate the diaphragmatic protein expression of myostatin and its correlation with apoptosis in a rat model of CPOD. Sprague Dawley rats were randomly divided into a control group and a COPD group, the latter of which were exposed to cigarette smoke to build a rat model of COPD. The validity of the COPD model was evaluated by assessment of lung function and histopathological analysis. Diaphragmatic myostatin expression and apoptosis were measured by western blot and terminal deoxynucleotidyl transferase deoxyuridine triphosphate nick end labeling, respectively. The rat model of COPD was efficiently established by cigarette smoke exposure. Diaphragmatic myostatin expression and apoptotic index in COPD rats were obviously increased as compared with that in the control animals. A positive correlation between diaphragmatic myostatin expression and apoptotic index was identified (r=0.857). Diaphragmatic myostatin overexpression in rats with COPD may promote diaphragmatic apoptosis and atrophy, leading to diaphragm weakness and respiratory muscle dysfunction, which is involved in the pathology of COPD. PMID- 29456637 TI - Effects of astrogaloside on the inflammation and immunity of renal failure patients receiving maintenance dialysis. AB - Chronic renal failure is a type of clinical syndrome originating from chronic renal diseases. The aim of the study was to investigate the effect of astrogaloside on the inflammation and immunity of renal failure patients receiving maintenance dialysis. We randomly selected 92 renal failure patients receiving maintenance dialysis who were admitted to hospital for treatment between May, 2015 and April, 2016. Patients were randomly divided into the control (n=46) and observation (n=46) groups. Patients in the control group received the regular dialysis plus the basic treatment in Western medicine, while in the observation group, patients additionally received astrogaloside via intravenous injection as treatment. We compared the clinical efficacy of patients between the two groups, residual renal function (RRF), changes in urine volume, variations in inflammatory indicators [C-reaction protein (CRP), interleukin-6 (IL-6), IL-17, and tumor necrosis factor-alpha (TNF-alpha)] before and after treatment, and the levels of the thymus-dependent lymphocyte (T cells) subgroup (CD3+, CD4+, CD8+ and CD4+/CD8+) in the immune system of patients after treatment. In the observation group, the total effective rate was significantly higher than that in the control group (P<0.05). After 6 months, RRF and the urine volume of patients in the two groups were decreased when compared with the levels before treatment, and the decreasing rates of RRF and urine volume in the observation group were significantly lower than those in the control group (P<0.05). After treatment, the levels of human serum C reaction protein (hs-CRP), IL-6, IL-17 and TNF-alpha in the two groups were lower than those before treatment, and the decrease in the observation group was more significant than that in the control group (P<0.05). Following treatment, the levels of CD3+, CD4+ and CD4+/CD8+ in the observation group were higher than those in the control group, and the level of CD8+ was lower than that in the control group (P<0.05). In conclusion, astrogaloside can delay the decrease in RRF of renal failure patients receiving the maintenance dialysis, ameliorate the inflammatory responses, and enhance the immune function, thereby increasing the disease resistance of patients and improving the clinical symptoms. PMID- 29456638 TI - Biobran/MGN-3, an arabinoxylan rice bran, enhances NK cell activity in geriatric subjects: A randomized, double-blind, placebo-controlled clinical trial. AB - Aging is associated with a decline in natural killer (NK) and natural killer T (NKT) cell function that may contribute to increased susceptibility to malignancy and infection. A preliminary investigation was conducted examining the hypothesis that arabinoxylan rice bran (Biobran/MGN-3), a denatured hemicellulose with known immunomodulatory activity, could counteract this decline in NK/NKT cell activity in geriatrics. A total of 12 healthy geriatric subjects of both sexes and over 56 years old, participated in a randomized, double-blind, placebo-controlled clinical trial. A total of six subjects served as control and six subjects ingested Biobran/MGN-3 (500 mg/day) for 30 days. The effect of Biobran/MGN-3 supplementation on NK/NKT cell activity was assessed using the degranulation assay. All study subjects were monitored for the development of any inadvertent side effects. In addition, the pharmacological effects of Biobran/MGN-3 on blood cell components and liver and kidney functions were also assessed. Results demonstrated that Biobran/MGN-3 had no effect on the total percentage of NK cells, however it enhanced the cytotoxic activity of induced NK cell expression of cluster of differentiation 107a, when compared with baseline values and with the placebo group (P<0.05). Furthermore, there were no side effects observed, indicating that Biobran/MGN-3 supplementation was safe at the utilized dosage and for the duration of administration. Various additional beneficial effects were observed, including improved mean corpuscular volume and reduced hepatic aspartate aminotransferase enzyme levels, which suggested improved liver function. It was concluded that Biobran/MGN-3 induces a significant increase in NK activity which may increase resistance to viral infections and cancers in the geriatric population. However, additional clinical trials should be conducted in the future to verify these findings. PMID- 29456639 TI - Analysis of effect of 1alpha-hydroxyvitamin D3 on benign paroxysmal positional vertigo and risk factors. AB - The purpose of this study was to investigate the curative effect of 1alpha hydroxyvitamin D3 on the benign paroxysmal positional vertigo (BPPV). Fifty BPPV patients diagnosed in the ENT Department of Anzhen Hospital from October 2015 to December 2016 were randomly selected as the treatment group, and treated with 0.25 ug 1alpha-hydroxyvitamin D3 once per day, in addition to the routine diagnosis and treatment. Moreover, 50 BPPV patients in the same period were selected as the control group, and received the routine diagnosis and treatment. The detection results of bone mineral density (BMD) t-value, vitamin D3 and bone metabolic markers before and after treatment were compared, and statistical analysis was performed on the results. There were no differences in the general data between treatment group and control group. There were no statistically significant differences in the BMD and age distribution of males and females between treatment group and control group (P>0.05). The BMD of male BPPV patients in each age group in the treatment group was significantly increased after treatment, and the difference was statistically significant (P<0.05). Although the BMD of male BPPV patients in each age group in control group was somewhat increased after treatment, the difference was not statistically significant (P>0.05). The BMD of female BPPV patients in each age group in treatment group was increased after treatment, and the difference was statistically significant (P<0.05). Similarly, although the BMD of female BPPV patients in each age group in control group was somewhat increased after treatment, the difference was not statistically significant (P>0.05). The average BMD of female BPPV patients in each age group was significantly lower than that of male patients, and the difference was statistically significant (P<0.05) (Table II). The BMD t-value of patients in treatment group showed a decreasing trend with the increase of age (Fig. 1). The levels of 25-hydroxyvitamin D3 and bone metabolic markers in treatment group were significantly improved compared with those before treatment (P<0.05). Multivariate Logistic regression analysis was performed to identify whether the treatment of BPPV was effective or not as a dependent variable, and six items, including the sex (female), hypertension, diabetes mellitus, age (>50 years), 25-hydroxyvitamin D3 and osteopenia/osteoporosis, as the independent variables, and the results suggested that the level of 25-hydroxyvitamin D3 and osteopenia/osteoporosis are the clinical features of whether the BPPV treatment is effective (P<0.05). The results showed that the treatment of BPPV with 1alpha hydroxyvitamin D3 can effectively improve the symptoms of patients, and the level of vitamin D3 and the occurrence of osteopenia/osteoporosis are the clinical indexes of whether the BPPV treatment is effective. PMID- 29456640 TI - Comparative study of ultrasonic elastography and conventional ultrasound in diagnosis of malignant anus neoplasm. AB - The application value of conventional ultrasound and ultrasonic elastography (UE) in preoperative diagnosis and combined diagnosis of malignant anus neoplasms was investigated. One hundred and twenty patients, whose mass was detected by digital rectal examination, were examined using UE and conventional ultrasound before operation, and the results were compared with those of histopathological examinations after operation, so that the accuracy and imaging features of UE as well as UE combined with conventional ultrasound in diagnosing malignant anus neoplasm were analyzed. Among the 120 patients, 77 were diagnosed with benign lesions and 43 were diagnosed with malignant lesions via pathological diagnosis for anal canal lesion surgery. Conventional ultrasound before operation showed that 53 patients were diagnosed with benign lesions and 26 with malignant lesions. Compared with that in the pathological diagnosis results, the diagnostic accordance rate in preoperative conventional ultrasound was 65.8%. Through UE diagnosis, 66 patients had benign lesions and 39 patients had malignant lesions. Compared with that in the pathological diagnosis results, the diagnostic accordance rate in preoperative UE was 87.5%. After the examination via UE combined with conventional ultrasound before operation, 71 patients were diagnosed with benign lesions and 40 patients were diagnosed with malignant lesions; compared with that in the pathological diagnosis results, the diagnostic accordance rate was 92.5%. In terms of mass qualitative diagnosis, the sensitivity and specificity of conventional ultrasound were 60.5 and 68.8%, respectively; those of UE were 90.7 and 85.7%, respectively, and those of UE combined with conventional ultrasound were 93.0 and 92.2%, respectively. According to the analysis results of receiver operating characteristic (ROC) curve, the area under curve (AUC) of malignant anus neoplasm diagnosed via UE was 0.732 [95% confidence interval (95% CI), 0.211-2.534], the AUC via conventional ultrasound was 0.695 (95% CI, 0.517-0.932), and that via UE combined with conventional ultrasound was 0.823 (95% CI, 0.146-4.643). In conclusion, examinations utilizing UE combined with conventional ultrasound can increase the preoperative diagnostic accordance rate in malignant anus neoplasm, which can be used as an effective method for preoperative diagnosis of malignant anus neoplasm. PMID- 29456641 TI - Multiple-site bleeding at pleural adhesions and massive hemothorax following percutaneous coronary intervention with stent implantation: A case report. AB - An elderly male patient with coronary heart disease underwent coronary angiography, which revealed bilateral severe coronary artery stenosis. Four stents were implanted, and at 5 h post-surgery, typical hemorrhagic shock appeared. Echocardiography verified heavy bleeding in the right thoracic cavity. Emergency angiography excluded injury or perforation of the coronary artery, aorta, right subclavian artery and brachiocephalic artery. Considering the patient's history of chronic obstructive pulmonary disease and severe cough during the operation, it was suspected that hemothorax was induced by a blood vessel rupture in the pleura. Video-assisted thoracic examination confirmed the tearing of pleural adhesion bands and bleeding at three sites in the pulmonary pleura and parietal pleura. According to the reported case, bleeding as a result of the laceration of pleural adhesions is an important cause of hemothorax that should be considered after exclusion of other common causes of pleural hemorrhage. PMID- 29456642 TI - Anti-Semaphorin-7A single chain antibody demonstrates beneficial effects on pulmonary inflammation during acute lung injury. AB - Pulmonary inflammation is a primary characteristic of lung injury initiated by the accession of immune cells into the alveolar space. Neutrophil migration serves an important role in pulmonary inflammation mediated by the migration of neutrophils into hypoxic tissue sites. The elimination of pulmonary inflammation is directly associated with rehabilitation in patients with lung injury. Anti inflammatory treatment is essential following lung injury and ultimately determines patient outcomes. Semaphorin-7A (SEMA-7A) is a member of the Semaphorin family that influences the migration of neutrophils into hypoxic tissue sites, thus promoting inflammation. However, understanding of the role of SEMA-7A serves during lung injury is limited and the immunological function of SEMA-7A during the migration of neutrophils into acute injury sites remains unknown. The present study investigated SEMA-7A expression and constructed a single chain antibody for SEMA-7A (Anti-SEMA-7A) to study its therapeutic efficacy against pulmonary inflammation in a mouse model of acute injury sites. The data indicated that the expression of SEMA-7A was upregulated due to induction by pro-inflammatory cytokines and demonstrated that Anti-SEMA-7A inhibited SEMA-7A expression in vitro and in vivo. The current study also indicated that the production of pro-inflammatory cytokines induced by SEMA-7A in endothelial and epithelial cells enhanced pulmonary inflammation. Anti-SEMA-7A suppressed the transendothelial migration of neutrophils mediated by SEMA-7A. Anti-SEMA-7A treatment neutralized SEMA-7A expression and reduced signs of pulmonary inflammation, leading to the elimination of pulmonary inflammation in rat with acute lung injury. The current study identified Anti-SEMA-7A as a potential agent to interfere with the inflammatory pathway during acute lung injury, which may be the basis for anti-inflammatory strategies to treat lung injuries in the future.

AB - The present case report described the initial diagnosis of a 25-year old female with a brain abscess consisting of two lesions 0.2 and 2.9 cm3 in volume. The patient was initially treated with antibiotics; however, 2 months following initial treatment, the patient's condition deteriorated and she became vegetative. Following transfer to the China-Japan Union Hospital of Jilin University (Jilin, China) the two lesions had grown in volume to 9.0 and 13.0 cm3, respectively. The results of magnetic resonance spectroscopy and plasma 1-3 beta-D-glucan activity suggested a possible fungal infection. Subsequently, a stereotactic biopsy was conducted, fluid was cultured and itraconazole treatment was initiated. Analysis of cultures confirmed a Candida glabrata infection and antifungal treatment was continued. Shortly following surgery, the patient regained consciousness and the ability to eat and speak. A follow-up MRI 8 months following biopsy confirmed disappearance of all lesions and no recurrence. To the best of our knowledge, this is the first English-language report of a brain abscess caused primarily by Candida glabrata.

AB - Eudesmin has been proven to possess anti-inflammatory effects. In the present study, the effects of eudesmin on Helicobacter pylori (H. pylori)-mediated autophagy, apoptosis, immune response and inflammation were determined in human gastric adenocarcinoma (AGS) cells in vitro and in C57BL/6 mice in vivo. Detection of the production of interleukin (IL)-8, IL-1beta and immunoglobulin M (IgM) was performed using ELISA. Identification of the activation of apoptosis associated caspase-3, -8 and -9 proteins, Bcl-2-associated X protein (Bax) and BH3 interacting domain death agonist (Bid) protein, was determined through western blot analysis. Autophagy microtubule-associated protein 1A/1B-light chain 3, isoform B (LC-3B) expression was measured using immunostaining. The results of the present study demonstrated that eudesmin inhibited the growth of H. pylori, with increased inhibition activity against antibiotic resistant strains compared with the reference strain. In addition, H. pylori-induced IL-8 secretion, LC-3B expression and apoptosis-associated protein (caspase-3, -8 and -9, Bax and Bid) activation in AGS cells was suppressed by eudesmin. Furthermore, eudesmin suppressed IL-1beta and IgM production in H. pylori-infected C57BL/6 mice in vivo. In conclusion, eudesmin may be developed as a promising therapeutic agent to prevent and/or treat H. pylori-associated gastric inflammation. PMID- 29456645 TI - Influence of exposure to nicotine during pregnancy on the learning and memory for adult offspring. AB - We aimed to investigate the indirect influence of exposure to nicotine during pregnancy on the learning and memory of adult offspring mice. Thirty pregnant C57 mice were randomly divided into either the control group (CON) or the nicotine group (NIC), with 15 mice each. The CON group was given access to drug-free water, and the NIC group was given 60 g/ml nicotine in drinking water. Sixteen adult mice were randomly selected from the 8 litters for Morris water maze test. The level of products of related factors in the hippocampus of mice in the NIC and the CON groups were compared using the 1H-MRS method. The escape latency time that the adult offspring mice in the NIC group took in the place navigation test was significantly longer than that of the CON group. In addition, the NIC group took longer time to arrive at the plate than the CON group (P<0.05). mRNA and protein levels of NR1 in the hippocampus of the NIC group was significantly higher than that in the CON group (P<0.05).alpha7nACh mRNA in the hippocampus of the NIC group was not significantly different from that of the CON group (P>0.05), while the expression levels of alpha7nACh protein in the hippocampus of the NIC group was significantly lower than that in the CON group (P<0.05). Detection of protein level of muscarinic receptors in the hippocampus of adult offspring mice in the NIC group showed that when compared to the CON group, the expression levels of M1, M3, M5 of the NIC group was not significantly different from that of the CON group (P>0.05). Therefore, exposure to nicotine during pregnancy can cause damage to the learning ability of adult offspring mice but do not significantly influence their working memory. PMID- 29456646 TI - An experimental rabbit model of symptomatic cerebral vasospasm with in vivo neuroimaging assessment and ex vivo histological validation. AB - Cerebral vasospasm (CVS) is a severe complication that occurs following aneurysmal subarachnoid hemorrhage (SAH). Magnetic resonance angiography (MRA) has been used to evaluate brain injury following SAH in humans. The present study was designed to assess a rabbit model of symptomatic CVS (SCVS) and the utility of MRA in evaluating SCVS in rabbits. Japanese white rabbits (n=24) were randomly divided into 2 equal groups: A sham group and a SAH group. Neurological scores were evaluated for 7 days following SAH. Basilar artery (BA) diameters were measured using MRA preoperatively and 7 days postoperatively. Rabbits were sacrificed 7 days following SAH and the BA diameter of each rabbit was determined using histological evaluation. Compared with the Sham group, neurological function was significantly reduced in the SAH group at all time points (P<0.05). Furthermore, the BA diameter was significantly smaller in the SAH group on day 7 compared with the baseline measurement (P<0.05). No significant difference was observed between histological and MRA findings in either group at day 7. Histological changes in the hippocampus consistent with ischemia were observed in the SAH group. Hippocampal ischemia was also identified in the SAH group via MRA and there was no difference in detection rates following the use of MRA and histochemistry. MRA appears to be an effective method for assessing vasospasms of the BA and ischemic changes to the hippocampus in a rabbit model of SCVS. Furthermore, the animal model used in the present study may be beneficial for the future study of SCVS. PMID- 29456647 TI - Comparison of mono- and combination antibiotic therapy for the treatment of Pseudomonas aeruginosa bacteraemia: A cumulative meta-analysis of cohort studies. AB - It is currently unknown whether antibiotic monotherapy or combination therapy is a more effective treatment for patients with Pseudomonas aeruginosa bacteraemia. The present study consists of a systematic review and meta-analysis of cohort studies in associated studies. The treatment options of monotherapy and combination therapy have been compared, to determine which is more effective against P. aeruginosa bacteraemia. Several electronic bibliographic databases were systematically searched and clinical studies that compared combination therapy with monotherapy for P. aeruginosa bacteraemia were identified. Dersimonian and Laird's random-effects models were used to generate summary estimates of the effects and to assess their association according to different patient characteristics and research quality standards. A total of 17 studies were selected, 3 of which were prospective while the remaining 14 were retrospective. The studies involved a total of 2,504 patients. Significant differences between combination therapy and monotherapy treatment were not found when the data were combined (odds ratio (OR)=0.81, 95% confidence interval (CI)=0.61-1.08; P=0.035). The results demonstrated strength in a number of stratification and sensitivity analyses. The variables used included study type, treatment quality score and survival rate of subgroup analysis. To conduct cumulative meta-analysis, the number of years and samples were calculated. The OR value and 95% CI were stable and demonstrated good change trend. According to the size of the sample order following accumulation, OR values and 95% CI (0.89, 0.76 1.04) exhibited a narrow range. Neither combination therapy or monotherapy exhibited significant effects on the mortality of patients with P. aeruginosa bacteraemia. Future research is required and should include large, well-designed prospective cohorts, and grouped clinical studies. PMID- 29456648 TI - Immunosuppressive effects of hydroxychloroquine and artemisinin combination therapy via the nuclear factor-kappaB signaling pathway in lupus nephritis mice. AB - Lupus nephritis (LN) is one of the most common and severe manifestations of systemic lupus erythematosus, leading to permanent renal damage and chronic kidney disease. Hydroxychloroquine (HCQ) serves a protective role against lupus associated clinical manifestations and medical complications; however, it results in numerous adverse reactions, limiting its long-term use. The aim of the present study was to investigate the combined effect of HCQ and artemisinin (ART) on LN, and to elucidate the underlying mechanisms. An in vivo LN mouse model was prepared, and the animals were administered prednisone (PDS; serving as a positive control), high-dose HCQ (H-HCQ) or low-dose HCQ combined with ART (L-HCQ + ART) once daily for 8 weeks. The body weight, serum biochemical parameters, immune and inflammatory indicators, renal and spleen histological alterations, and mRNA expression levels of Kruppel-like factor 15 (KLF15) and nuclear factor kappaB (NF-kappaB) were analyzed. It was observed that L-HCQ + ART and H-HCQ ameliorated the LN-induced body weight decrease, and significantly decreased the levels of anti-double stranded DNA, antinuclear antibodies, immunoglobulin G, interferon gamma, tumor necrosis factor-alpha and transforming growth factor beta1, as well as improved the kidney and spleen pathology, when compared with the model group. In addition, L-HCQ + ART and H-HCQ treatments induced KLF15 upregulation and NF-kappaB downregulation. These results indicated that treatment with L-HCQ + ART exerted renoprotective effects by regulating the expression levels of cytokines, KLF15 and NF-kappaB. This combination treatment may have a similar immunosuppressive effect as PDS and H-HCQ, and may be a promising alternative for LN treatment. PMID- 29456649 TI - Protective effect of miconazole on rat myelin sheaths following premature infant cerebral white matter injury. AB - The aim of the present study was to investigate the protective effects of miconazole on myelin sheaths following cerebral white matter damage (WMD) in premature infant rats. Sprague Dawley rats (3-days-old) were randomly divided into four groups (n=30 each) as follows: Sham surgery group, WMD model group, 10 mg/kg/day treatment group and 40 mg/kg/day treatment group. A cerebral white matter lesion model was created by ligating the right common carotid artery for 80 min. Treatment groups were administered with 10 or 40 mg/kg miconazole at 4-8 days following birth (early treatment group) or 5-11 days following birth (late treatment group). Rats in the model group received the same concentration of dimethylsulfoxide. Myelin basic protein (MBP) immunohistochemical staining and western blotting were used to detect the expression of cerebral white matter specific MBP, and changes in myelin structure were observed using transmission electron microscopy. No swelling or necrosis was observed in the corpus callosum of the sham group rats, whereas rats in the model group demonstrated edema, loose structure, fiber disorder, inflammatory gliocytes and selective white matter lesions. Following treatment with miconazole, MBP expression in the corpus callosum was significantly higher compared with the model group. Furthermore, in the model group, myelin sheaths in the corpus callosum were loose with small vacuoles, there was a marked decrease in thickness and structural damage was observed. Conversely, a marked improvement in myelination was observed in the treatment group. The results of the present study suggest that miconazole is able to promote formation of the myelin sheath to ameliorate premature cerebral white matter lesions caused by ischemia or hypoxia in rats. PMID- 29456650 TI - Application of an acellular dermal matrix to a rabbit model of oral mucosal defects. AB - Acellular dermal matrices (ADMs) are increasingly used for the restoration of soft-tissue defects of the oral cavity due to their ability to facilitate faster healing and reduce scar formation without rejection. However, few studies have focused on the histopathology and biological mechanisms involved in their use. The aim of the present study was to observe tissue growth, histopathologic changes and altered biomolecular signatures that occur during the repair of oral defects in rabbit models over time, either with or without the employment of ADM. Animals were sacrificed 1, 2 and 4 weeks following surgery and histological changes were evaluated using hematoxylin and eosin staining. Reverse transcription-polymerase chain reaction and western blot analysis were used to determine changes in the expression of vascular endothelial growth factor (VEGF) and glucose transporter 1 (GLUT1). It was demonstrated that wounds treated with ADM exhibited a weak inflammatory reaction and faster epithelialization and revascularization compared with untreated wounds. This may have been caused by the elevated levels of VEGF and GLUT1 protein detected in the ADM-treated defects. Thus, treating wounds of the oral mucosa with an ADM improves pathological responses compared with those with an untreated wound. The current study demonstrates the underlying mechanisms by which ADM promotes wound healing in defects of the oral mucosa and the results provide further evidence for the use of ADM in clinical settings for the repair of mucosal defects. PMID- 29456651 TI - Protective effect of black garlic extracts on tert-Butyl hydroperoxide-induced injury in hepatocytes via a c-Jun N-terminal kinase-dependent mechanism. AB - Black garlic has been reported to show multiple bioactivities against the development of different diseases. In the present study, the hepatoprotective effect of black garlic on injured liver cells was investigated. Rat clone-9 hepatocytes were used for all experiments; tert-Butyl hydroperoxide (tBHP) was used to induce injury of rat clone-9 hepatocytes. The contents of malondialdehyde (MDA) and glutathione (GSH); anti-oxidative enzyme activities of catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx); and mRNA expression levels of interleukin (IL)-6 and IL-8 in rat clone-9 hepatocytes were determined to evaluate the level of cell damage. Black garlic extracts were demonstrated to significantly attenuate tBHP-induced cell death of rat clone-9 hepatocytes (P<0.05). Pretreatment with black garlic extracts antagonized GSH depletion, tBHP increased MDA accumulation and the mRNA expression level of IL-6/IL-8, and tBHP decreased antioxidative enzyme activities (all P<0.05). Moreover, the present study revealed that c-Jun N-terminal kinase signaling regulated black garlic inhibited tBHP effects in rat clone-9 hepatocytes. Our findings demonstrate that black garlic has the hepatoprotective potential to block tBHP-damaged effects on cell death, lipid peroxidation, oxidative stress, and inflammation in rat clone-9 hepatocytes. Thus, the present study indicates that black garlic may be an excellent natural candidate in the development of adjuvant therapy and healthy foods for liver protection. PMID- 29456652 TI - Analysis of the levels of Th9 cells and cytokines in the peripheral blood of mice with bronchial asthma. AB - The purpose of the study was to detect the level of T-helper type 9 (Th9) cells and the cytokine interleukin-9 (IL-9) in peripheral blood of mice with bronchial asthma, and to explore the relationship between the expression of Th9 cells and the pathogenesis of asthma. Thirty female-specific pathogen-free (SPF) Bagg' albino (BALB)/c mice were selected and randomly divided into the control group (n=15) and the bronchial observation group (n=15). Mice in the bronchial observation group were treated with ovalbumin (OVA) for sensitization and induction of a mouse model of asthma. The airway reactivity of mice was measured by a mouse pulmonary function apparatus using the non-invasive pulmonary impedance method. The proportions of Th9 cells in peripheral blood of mice in the two groups were detected using flow cytometry. Digital polymerase chain reaction (dPCR), enzyme-linked immunosorbent assay (ELISA) and western blot analysis were applied to detect the levels of IL-9 messenger ribonucleic acid (mRNA) and proteins in peripheral blood and lung tissues of mice in the two groups, respectively. Compared with that in the control group, the expression level of Th9 cells in the peripheral blood of mice in the observation group was significantly elevated (P<0.05), the expression level of IL-9 proteins in the peripheral blood was significantly increased (P<0.05), and the levels of IL-9 mRNA and proteins in lung tissues were significantly increased (P<0.05). The results show that the levels of Th9 cells and their cytokine IL-9 in the peripheral blood of mice with bronchial asthma are significantly increased, suggesting that Th9 cells play important roles in the pathogenesis of asthma. PMID- 29456653 TI - Metformin protects against oxidized low density lipoprotein-induced macrophage apoptosis and inhibits lipid uptake. AB - Oxidized low density lipoprotein (ox-LDL)-induced macrophage apoptosis contributes to the formation of atherosclerosis. Metformin, an antidiabetic drug, has been reported to attenuate lipid accumulation in macrophages. In this study, the effects of metformin on ox-LDL-induced macrophage apoptosis were investigated and the mechanisms involved in this process were examined. By performing flow cytometry analysis, it was demonstrated that metformin inhibited ox-LDL-induced macrophage apoptosis. Increased expression of endoplasmic reticulum (ER) stress marker proteins, including C/EBP-homologous protein, eukaryotic translation initiation factor 2A, and glucose-regulated protein 78 kDa, induced by ox-LDL was also reversed by metformin. Furthermore, ox-LDL-induced cytochrome c (cyto-c) release and mitochondrial membrane potential loss were inhibited by metformin. As lipid uptake in macrophages contributed to ER stress, cyto-c release and mitochondrial membrane potential loss, the mechanisms involved in metformin inhibited macrophage lipid uptake were investigated. Expression of scavenger receptors, including scavenger receptor A, cluster of differentiation 36 and lectin-type oxidized LDL receptor 1 was examined in the presence or absence of metformin with ox-LDL treatment. Additionally, the upstream regulatory mechanism of scavenger receptors by metformin was also analyzed. In conclusion, metformin protects against ox-LDL-induced macrophage apoptosis and inhibits macrophage lipid uptake. PMID- 29456654 TI - Establishment of different experimental asthma models in mice. AB - Asthma is a complex disease. The heterogeneity of airway inflammation during asthma indicates there are different mechanisms involved. In order to further study the mechanisms of asthma, different mouse models were established to mimic corresponding subtypes of asthma in clinic. Eosinophilic asthma was established by intraperitoneal injections of ovalbumin (OVA) on day 0 and day 7, followed by inhalation of aerosolized OVA on days 14-17. Neutrophilic asthma was established by transtracheal administration of a high dose of lipopolysaccharide (LPS; 10 ug) on days 15 and 17 in combination with OVA sensitization and challenge as described previously. Mix-granulocytic asthma was established by transtracheal administration of a low dose of LPS (1 ug) on day 15, in combination with OVA sensitization and challenge as described previously. Compared with healthy controls, increased numbers of eosinophils, elevated levels of T helper (Th)2 cytokines in bronchoalveolar lavage fluid (BALF), and moderated inflammation of lung tissues was observed in eosinophilic asthma. Increased numbers of neutrophils, elevated levels of Th1 and Th17 cytokines in BALF and severe inflammation of lung tissues was observed in neutrophilic asthma. Increased numbers of both eosinophils and neutrophils, elevated levels of Th1, Th2 and Th17 cytokines in BALF and severe inflammation of lung tissues was observed in mix granulocytic asthma. Airway hyperresponsiveness, increased bronchial mucus secretion, and elevated serum levels of immunoglobin (Ig)E and OVA-IgE were detected in all three asthma models. Dexamethasone reduced the pathogenic symptoms of the mice in eosinophilic asthma, however had no effect on neutrophilic asthma or mix-granulocytic asthma. Each model of asthma established in the present study represents corresponding subtypes of asthma in clinic. PMID- 29456656 TI - Comparison of the diagnostic efficacy between ultrasound elastography and magnetic resonance imaging for breast masses. AB - The present study compared the efficacy of ultrasound elastography (UE), magnetic resonance imaging (MRI) and the combination of the two methods (UE+MRI) in the differential diagnosis of benign and malignant breast tumors. In total, 86 patients with breast masses were recruited and evaluated by UE, MRI and UE+MRI. Strain ratios of UE were calculated for the breast mass and adjacent normal tissues. In addition, the receiver operating characteristic (ROC) curve was obtained, while the sensitivity and specificity were calculated to determine the optimal cut-off point for the differential diagnosis. The area under the ROC curve (AUC) was also calculated to evaluate the diagnostic performance of these methods. The results indicated that the diagnostic accuracy of UE+MRI was significantly higher compared with the UE or MRI methods in the differential diagnosis of invasive ductal, invasive lobular, intraductal papillary, medullary and mucinous carcinomas (all P<0.05). The optimal cut-off points of ROC curve of the Strain Ratio in the diagnosis of breast lesions were 2.81, 3.76 and 3.42 for UE, MRI and UE+MRI, respectively. Furthermore, the AUC values were 86.7, 79.2 and 91.4%, while the diagnostic accuracy rates were 82.5, 75.5 and 95.3%, for UE, MRI and UE+MRI, respectively. Accuracy rate differences between UE and MRI or between UE and UE+MRI were statistically significant (P<0.05), whereas no significant difference existed between MRI and UE+MRI (P>0.05). Finally, the diagnostic consistency of the UE+MRI method with the pathological diagnosis was higher compared with UE or MRI alone. In conclusion, the combination of UE and MRI is superior to the use of UE or MRI alone in the differential diagnosis of benign and malignant breast masses. PMID- 29456655 TI - Effect of immune tolerance induced by immature dendritic cells and CTLA4-Ig on systemic lupus erythematosus: An in vivo study. AB - Systemic lupus erythematosus (SLE) is a multi-organ autoimmune disease in which tissue damage is caused by autoantibodies. The induction of specific immune tolerance, including the utilization of immune regulatory cells, may enhance the therapeutic effects of organ transplantation in patients with SLE. Furthermore, inhibiting immune responses has been reported to be an effective treatment for SLE. However, few studies have explored the association between an increased immune tolerance and a decreased immune response in SLE treatment. Dendritic cells (DCs), which are highly efficient antigen-presenting cells, are able to induce specific tolerance, while cytotoxic T lymphocyte antigen 4-immunoglobulin (CTLA4-Ig) inhibits the immune response. In the present study, interleukin (IL) 10-treated DCs and CTLA4-Ig were administered to mice with SLE alone or in combination and the therapeutic effects were investigated. IL-10 was added into the culture medium of bone marrow-derived DCs to prevent them from differentiating into mature cells. Low levels of major histocompatibility complex II, cluster of differentiation (CD)40, CD80 and CD86 were detected, which indicated that the immature state of DCs was maintained. IL-10-treated DCs were subsequently injected into the caudal vein of B6.MRL-Faslpr/J lupus mice, which are an established animal model of SLE. To amplify the tolerance effect, mice were simultaneously injected with CTLA4-Ig. Compared with the IL-10-treated DC and CTLA4-Ig groups, combined treatment with IL-10-treated DCs and CTLA4-Ig strongly induced immune tolerance in mice with SLE, as indicated by the significantly reduced levels of urine protein, anti-nuclear antibody, double stranded DNA and IL-17A. A significant decrease in the proportion of T helper cells and an increase in the proportion of CD4+ forkhead box protein P3+ Treg cells was also observed, further confirming the induction of immune tolerance. These results suggest that combined treatment with IL-10-DCs and CTLA4-Ig may be a promising novel therapeutic strategy for the treatment of SLE. PMID- 29456657 TI - Intramuscular primary immunization by nucleic acid vaccine pcDNA/Gpd-IL-2 and enhanced immunization with mucosal adjuvant CpG-ODN and Gpd-IL-2 recombinant protein effectively induced strong mucosal immune responses and immune protective effects against Treponema pallidum skin infection. AB - The present study aimed to evaluate the immune effect of intramuscular primary immunization by the nucleic acid vaccine pcDNA/glycerophosphodiester phosphodiesterase-interleukin-2 (pcDNA/Gpd-IL-2) and enhanced immunization 2 weeks later with the combination of mucosal adjuvant CpG-oligodeoxynucleotides (ODN) and Gpd-IL-2 recombinant protein on skin infection caused by Treponema pallidum (Tp) in New Zealand rabbits. At week 8 following immunization, MTT assay was used to detect spleen cell proliferation, while enzyme-linked immunosorbent assay was performed to detect the cytokine and secretory immunoglobulin A (SIgA) levels. At week 10 after primary immunization, rabbits were inoculated with 105 Tp (Nichols strain). Alterations in the skin redness, swelling and ulceration were recorded for 0-60 days. In addition, positive rate of Tp in skin lesions and ulcer formation rate were examined using dark field and silver staining. The results indicated that intramuscular primary immunization by nucleic acid vaccine pcDNA/Gpd-IL-2 followed by enhanced immunization via nasal feeding with mucosal adjuvant CpG-ODN and Gpd-IL-2 recombinant protein induced the higher levels of Tp Gpd specific antibodies, increased the secretion of IL-2 and interferon-gamma, and promoted the proliferation of T cells in the first 8 weeks after immunization. Furthermore, this immunization strategy stimulated the production of mucosa specific SIgA antibody. Thus, this strategy led to the lowest Tp positive and ulcer formation rates at the Tp infection sites, as well as healing of skin lesions on the earliest time point (day 42). In conclusion, immunization by nucleic acid vaccine pcDNA/Gpd-IL-2 followed by enhanced immunization with a combination of mucosal adjuvant CpG-ODN and Gpd-IL-2 recombinant protein is an effective immune strategy to induce strong mucosal immune responses and immune protective effects. PMID- 29456659 TI - PRMT1-RBM15 axis regulates megakaryocytic differentiation of human umbilical cord blood CD34+ cells. AB - Protein arginine methyltransferase 1 (PRMT1) serves pivotal roles in various cellular processes. However, its role in megakaryocytic differentiation has not been clearly reported. The aim of the present study was to explore the role of the PRMT-RNA binding motif protein 15 (RBM15) axis in human MK differentiation and the feasibility of targeting PRMT1 for leukemia treatment. In the present study, PRMT1 was overexpressed and the RBM15 protein was knocked down in human umbilical cord blood cluster of differentiation (CD)34+ cells and the cells were then cultured in megakaryocytic differentiation medium. Flow cytometry was used to analyze CD41 and CD42 double-positive cells, as well as the protein expression levels of PRMT1 and RBM15. The results demonstrated that human cord blood CD34+ cells differentiate into mature MKs in high thrombopoitin medium, as demonstrated by CD41 and CD42 expression. Overexpression of PRMT1 in human umbilical cord blood CD34+ cells blocked the maturation of megakaryocytic cells. Knockdown of RBM15 by short hairpin RNA produced less mature MKs. PRMT1 inhibitor rescued PRMT1-blocked megakaryocytic differentiation. These results provide evidence for a novel role of PRMT1 in the negative regulation of megakaryocytic differentiation. PRMT1 may be a therapeutic target for leukemia treatment. PMID- 29456658 TI - Expression of Clara cell 10-kDa protein and trefoil factor family 1 in patients with chronic rhinosinusitis and nasal polyps. AB - The current study measured the expression of Clara cell 10-kDa protein (CC10) and trefoil factor family 1 (TFF1) in the sinus mucosa of patients exhibiting chronic rhinosinusitis (CRS) and nasal polyps (NP). CC10 and TFF1 expression in the sinus mucosa of the control group and patients with CRS and NP was determined using reverse transcription-quantitative polymerase chain reaction (RT-qPCR), western blotting and immunohistochemistry. The correlation between CC10 and TFF1 expression was further analyzed using Spearman's correlation analysis. The expression of TFF1 was significantly increased in the sinus mucosa of patients with CRS and NP, whereas CC10 expression was significantly decreased compared with controls. Spearman's correlation analysis identified a negative correlation between CC10 and TFF1 expression in the sinus mucosa of patients with CRS and NP. The results of immunohistochemistry and RT-qPCR were consistent with each other. Hematoxylin and eosin staining revealed notable lesions in the mucous membranes, goblet cells and cilia of sinus mucosa samples from patients with CRS and NP. The negative correlation between CC10 and TFF1 expression during the progression of CRS and NP suggest that CC10 and TFF1 may serve important roles in its pathogenesis. PMID- 29456660 TI - The role of miR-766-5p in cell migration and invasion in colorectal cancer. AB - Colorectal cancer (CRC) develops from the colon or rectum and is the fourth highest inducer of cancer mortality. In the present study, cancer tissues and normal tissues were extracted from patients with CRC who were treated in the Affiliated Hospital of Shandong University of Traditional Chinese Medicine (Jinan, China). Reverse transcription-quantitative polymerase chain reaction demonstrated that the expression level of miR-766-5p was significantly higher (P<0.01) in cancer tissue than that in normal tissue. SW480 cells were used for in vitro study and randomly separated into the miR-negative control (NC) inhibitor treatment group and miR-766-5p inhibitor treatment group. SW480 cell behaviors were evaluated. Results demonstrated that in the miR-766-5p inhibitor group, there was a decreased level of cell proliferation/migration/invasion and higher cell apoptosis compared with that in the miR-NC inhibitor group. miR-766 5p was predicted and verified to target the 3' untranslated region of suppressor of cancer cell invasion (SCAI) in SW480 cells. Protein expression levels of matrix metalloproteinase-2/phosphoinositide 3-kinase/AKT were decreased and SCAI was increased following miR-766-5p inhibitor treatment. In conclusion, the present study indicated that miR-766-5p inhibitor repressed the process of CRC by targeting SCAI. PMID- 29456661 TI - Anticancer activity of 23,24-dihydrocucurbitacin B against the HeLa human cervical cell line is due to apoptosis and G2/M cell cycle arrest. AB - Cervical cancer is one of the primary causes of cancer-associated mortality worldwide. Due to the increasing incidence of cervical cancer, multiple treatment options are required. Initial responses to chemotherapy and surgical interventions are generally positive, however patients often experience relapse and tumor recurrence. Currently, the effects of cucurbitacins on different types of cancer are being investigated, as they exhibit a wide variety of bioactivities. The anticancer activity of the cucurbitacin 23,24 dihydrocucurbitacin B against a panel of human cervical cancer cell lines was investigated in the current study. Cell viability was determined using an MTT assay and apoptosis was detected using DAPI staining. The proportion of apoptotic cells, cell cycle distribution, mitochondrial membrane potential (DeltaPsim) and reactive oxygen species (ROS) levels were estimated using flow cytometry. Protein expression was determined using western blot analysis. The results of the current study indicated that 23,24-dihydrocucurbitacin B inhibited the viability of human cervical cancer cell lines and had an IC50 of 40-60 uM. However, its cytotoxic effects were much less pronounced in normal epithelial fr2 and HerEpiC cells, where it had an IC50 of 125 uM. The underlying mechanisms of this were further studied and the results demonstrated that 23,24-dihydrocucurbitacin B induced apoptosis in HeLa cells and caused ROS-mediated shifts in the DeltaPsim. Additionally, it caused the cell cycle arrest of HeLa cells at the G2/M checkpoint. The phosphoinositide 3 kinase/protein kinase B/mechanistic target of rampamycin (PI3K/AKT/mTOR) cascade may serve an important role in cancer tumorigenesis, progression and resistance to chemotherapy. The results indicated that 23,24-dihydrocucurbitacin B significantly decreased the expression of important proteins in the PI3K/Akt/mTOR cascade. Taken together, these results suggest that 23,24-dihydrocucurbitacin B may be novel method of treating cervical cancer. PMID- 29456662 TI - MicroRNA profiles of BMSCs induced into osteoblasts with osteoinductive medium. AB - MicroRNA (miRNA) plays an important role in cell differentiation and functions as a regulator. Therefore, miRNA is important in the process of bone marrow mesenchymal stem cells (BMSCs) being induced into osteoblasts. In this study, mouse BMSCs were induced with osteoinductive medium, the indices related to osteoblastic differentiation were assayed, including alkaline phosphatase, the deposit of calcium and protein levels of osteocalcin. Using miRNA microarray and reverse transcription-quantitative polymerase chain reaction analyses, differentially expressed miRNAs in the cells, which were induced with osteoinductive medium, were selected and identified. The target genes of the differentially expressed miRNAs were then predicted using bioinformatics analysis. The results revealed that osteoinductive medium promoted osteoblastic differentiation of BMSCs, and let-7c-5p, miR-181c-3p, miR-3092-3p and miR-5132-3p were identified as differentially expressed miRNAs in the cells treated with osteoinductive medium for 14 and 21 days. Certain target genes and signal pathways related to osteoblastic differentiation of the four miRNAs were predicted. These findings indicated the four differently expressed miRNAs may be potential regulators of osteoblastic differentiation, providing a basis for further study on the regulation of miRNAs in the osteogenic differentiation of BMSCs. PMID- 29456663 TI - High expression of SDF-1 and VEGF is associated with poor prognosis in patients with synovial sarcomas. AB - Stromal cell-derived factor-1 (SDF-1) predicts poor clinical outcomes of certain types of cancer. Furthermore, vascular endothelial growth factor (VEGF) promotes the growth and metastasis of solid tumors. The aim of the present study was to examine the expression of SDF-1 and VEGF in patients with synovial sarcoma and to determine their expression is correlated with unfavorable outcomes. Levels of SDF 1 and VEGF proteins were evaluated in 54 patients with synovial sarcoma using immunohistochemical and immunofluorescence staining. Potential associations between the expression of SDF-1 and VEGF and various clinical parameters were analyzed using Pearson's chi2 test and the Spearman-rho test. Additionally, univariate and multivariate Cox regression analyses were used to identify potential prognostic factors, and the Kaplan-Meier method was used to analyze the overall survival rates of patients. Low SDF-1 and VEGF expression was detected in 20.4% (11/54) and 22.2% (12/54) of patients with synovial sarcoma; moderate expression was detected in 35.2% (19/54) and 37.0% (20/54) of patients and high expression was detected in 44.4% (24 of 54) and 40.7% (22 of 54) of patients, respectively. Levels of SDF-1 and VEGF proteins were significantly associated with histological grade (P<0.05), metastasis (P<0.05) and American Joint Committee on Cancer staging (P<0.05). In addition, levels of SDF-1 and VEGF expression were positively correlated with each other (P<0.001). Univariate analysis also indicated that VEGF expression was associated with shorter overall survival rates in (P<0.05), whereas multivariate analysis demonstrated that SDF-1 expression was associated with shorter patient survival rates (P<0.05). Finally, both SDF-1 and VEGF expression were associated with various characteristics of synovial sarcoma. Therefore, SDF-1 expression may be a potential independent prognostic indicator in patients with synovial sarcomas. PMID- 29456664 TI - Jinwei Tang modulates HDAC2 expression in a rat model of COPD. AB - The aim of the present study was to investigate the effect of a Traditional Chinese Herbal Medicine (TCHM), named Jinwei Tang on histone deacetylase 2 (HDAC2) and its role in the regulation of corticosteroid resistance in a rat model of chronic obstructive pulmonary disease (COPD). Male Wistar rats were divided into five groups (each n=10): COPD group, established by the intratracheal instillation of lipopolysaccharide and passive smoke exposure, and control, budesonide, theophylline + budesonide and Jinwei Tang + budesonide groups. Lung function was measured, lung tissue histopathology was examined and HDAC2 expression in the lung was assessed by immunohistochemistry. In addition, protein levels of interleukin-8 (IL-8), tumor necrosis factor (TNF)-alpha and HDAC2 in lung homogenate were quantified by ELISA. The rat COPD model exhibited alterations of the ratio of forced expiratory volume in 0.2 sec (FEV0.2) to the forced vital capacity, FEV0.2, dynamic compliance and airway resistance. HDAC2 expression was markedly reduced in the lung tissue of the COPD group compared with the control group, and treatment with Jinwei Tang + budesonide or theophylline + budesonide resulted in significant attenuation of the reduction of HDAC2 expression in the lungs (P<0.05). However, treatment with budesonide alone did not significantly alter HDAC2 expression. In the Jinwei Tang + budesonide and theophylline + budesonide groups, IL-8 and TNF-alpha expression was significantly decreased (P<0.05) and the HDAC2 level increased (P<0.05) compared with that in the COPD group. In conclusion, Jinwei Tang modulates airway inflammation and may enhance the anti-inflammatory effect of glucocorticoid through the upregulation of HADC2 expression in a rat model of COPD. PMID- 29456665 TI - Involvement of TWEAK and the NF-kappaB signaling pathway in lupus nephritis. AB - Previous findings have identified that tumor necrosis factor-related weak inducer of apoptosis (TWEAK) is associated with lupus nephritis (LN) activity status; however, the mechanism involved remains unclear. The present study aimed to investigate the roles of TWEAK and the nuclear factor (NF)-kappaB signaling pathway in LN. TWEAK levels in the blood and urine of patients with LN or non-LN systemic lupus erythematosus were measured by ELISA and compared with those in healthy controls. TWEAK expression and NF-kappaB transcriptional activity in the kidney were detected by western blotting, and Ki-67 and cluster of differentiation (CD) 68 expression were assessed using immunofluorescence. Additionally, human mesangial cells (HMCs) were cultured in vitro and divided into five groups: Normal control, TWEAK stimulus group, TWEAK + TWEAK blocking antibody, TWEAK + NF-kappaB inhibitor (BAY 11-7082) and TWEAK + combined (blocking antibody + BAY 11-7082). Cell cycle activity and Ki-67 expression in the HMCs were evaluated using flow cytometry, and cell induction of macrophage chemotaxis was determined by a Transwell assay. Levels of the inflammation associated factors interleukin (IL)-6, monocyte chemotactic protein 1 (MCP-1), chemokine ligand 5 (CCL5), IL-8 and IL-10 were also detected by reverse transcription-quantitative polymerase chain reaction. It was observed that the urine levels of TWEAK in patients with LN were significantly elevated compared with those in the other groups (P<0.05). LN kidneys exhibited markedly increased cell proliferative ability, macrophage infiltration, TWEAK expression and NF kappaB transcriptional activity compared with normal kidneys. Furthermore, the results indicated that treatment with recombinant TWEAK notably enhanced NF kappaB transcriptional activity and significantly promoted cell proliferation and cell cycle activity (P<0.05), induced macrophage chemotaxis (P<0.05), significantly increased the expression of the chemotactic factors IL-6, IL-8, MCP 1 and CCL5 (P<0.05), and significantly reduced anti-inflammatory cytokine IL-10 mRNA expression in HMCs (P<0.05), relative to normal controls. Accordingly, blocking TWEAK function or inhibiting NF-kappaB activity reversed these effects. Collectively these data indicate that urine TWEAK may be considered as a novel biomarker of LN activity, and that blocking TWEAK function or NF-kappaB activity may effectively alleviate glomerular mesangial cell proliferation and macrophage chemotaxis. PMID- 29456666 TI - MicroRNA-125b-1-3p mediates intervertebral disc degeneration in rats by targeting teashirt zinc finger homeobox 3. AB - The present study aimed to investigate the association between Teashirt zinc finger homeobox 3 (TSHZ3) and the nucleus pulposus (NP) of intervertebral discs in rats. TSHZ3 was identified from the differentially expressed micro (mi)RNAs in the expression profile of GSE63492 by identifying the overlapped target genes of microRNA (miR)-125b-1-3p across different databases. TSHZ3 small interfering RNA (siRNA) and an miR-125b-1-3p inhibitor were used for gene silencing and gene silencing efficiency was assessed by reverse transcription-polymerase chain reaction. Western blotting was performed to detect the cell cycle proteins cyclin D1 and B1 and the proteins associated with DNA damage in NP. The results revealed that in normal NPs, the expression of TSHZ3 increased following the inhibition of miR-125b-1-3p and in DNA damaged NPs, the expression of TSHZ3 was associated with the degree of DNA damage. The present study demonstrated that TSHZ3, as a target gene of miR-125b-1-3p, may serve a protective role in intervertebral disc degeneration and that this protective function may be inhibited by high levels of miR-125b-1-3p. PMID- 29456667 TI - In vitro study on reversal of ovarian cancer cell resistance to cisplatin by naringin via the nuclear factor-kappaB signaling pathway. AB - The aim of the present study was to investigate the mechanism of action by which naringin reverses the resistance of ovarian cancer cells to cisplatin. Semi quantitative reverse transcription polymerase chain reaction (RT-PCR) and western blotting assays were used to detect the effects of different concentrations of naringin on the expressions of nuclear factor (NF)-kappaB and P-glycoprotein (P gp) in the SKOV3/CDDP cell line. Small interfering RNA (siRNA) targeting NF kappaB was designed and synthesized to silence NF-kappaB, and recombinant plasmid vectors overexpressing NF-kappaB were constructed to transfect cells. RT-qPCR and western blotting assays were subsequently performed to detect the effects of NF kappaB on the expression of P-gp at the mRNA and protein levels. Naringin was added to the NF-kappaB-overexpressing SKOV3/CDDP cells and cultured for 48 h, followed by the detection of the expression of P-gp. RT-PCR and western blotting results demonstrated that the gene and protein expressions of NF-kappaB and P-gp were significantly decreased in a dose-dependent manner by naringin treatment (P<0.05). In cells overexpressing NF-kappaB, P-gp expression was significantly elevated (P<0.05), and the expression of P-gp was significantly decreased when NF kappaB was silenced (P<0.05). Treatment with naringin was able to significantly ameliorate the NF-kappaB-induced overexpression of P-gp (P<0.05). These results indicate that naringin is able to inhibit the expression of NF-kappaB and P-gp in SKOV3/CDDP cells. Such an inhibitory effect may increase gradually with concentration, and is associated with blockade of the NF-kappaB signaling pathway. This pathway may represent one of the mechanisms of action by which Naringin reverses resistance to platinum-based agents in ovarian cancer cells. PMID- 29456668 TI - FPOA induces the apoptosis of HepG2 cells. AB - The triterpenoid 3-acetoxylanosta-8,24-dien-21-oic acid (FPOA) is isolated from the fruiting body of Fomitopsis pinicola. The present study reports that FPOA exerts cytotoxic activity and describes the molecular mechanism of FPOA-induced apoptosis on human HepG2 hepatoma cells. FPOA exhibited significant cytotoxic effects against HepG2, MCF-7 and HeLa cells. However, FPOA was particularly cytotoxic towards HepG2 cells, with a half maximal inhibitory concentration value of 42.10 uM, thus these cells were taken forward for further analysis. Flow cytometry results demonstrated that FPOA significantly increased the apoptotic rate of HepG2 cells in a dose-dependent manner, explaining its potent cytotoxicity. In addition, western blot analysis revealed that FPOA significantly increased the B-cell lymphoma 2 (Bcl-2)-associated X/Bcl-2 ratio, and cytochrome c, caspase-9 and caspase-3 release, in addition to significantly decreasing poly(ADP) ribose polymerase levels. These observations indicate that FPOA induces the apoptosis of HepG2 cells by activating members of the caspase protein family and triggering the mitochondrial apoptosis signaling pathway. Based on these results, FPOA is a potential agent for the treatment of cancer. PMID- 29456669 TI - Expression of DACT1 in children with asthma and its regulation mechanism. AB - The aim of the present study was to detect DACT1 expression levels in the lungs of children with asthma, and to investigate its role and molecular mechanisms in regulating the expression of inflammatory factors in RAW264.7 cells. DACT1, DACT2 and DACT3 expression was analyzed in biopsy specimens from 10 cases of newly diagnosed children with asthma and 10 healthy controls by reverse transcription quantitative polymerase chain reaction, and their expression was confirmed in RAW264.7 cells. DACT1 expression was silenced by small interfering RNA or enhanced by transfection of pcDNA-3.1-DACT1 in RAW264.7 cells, and expression of beta-catenin and inflammatory factors, interleukin (IL) 5, IL6 and IL13, was analyzed. Nuclear translocation of beta-catenin was detected by western blot analysis, and the effect of DACT1 on beta-catenin was investigated with rescue experiments. Regulation of the Wnt signaling pathway by DACT1 and beta-catenin was analyzed in RAW264.7 cells after recombinant Wnt5A stimulation. DACT1, DACT2 and DACT3 were significantly upregulated in specimens from children with asthma compared with controls (P<0.05) and the expression of DACT1 was significantly more increased compared with DACT2 and DACT3 (P<0.05). Inhibition of DACT1 expression significantly suppressed IL5, IL6 and IL13 mRNA expression levels compared with the control (P<0.05), while upregulated DACT1 expression significantly increased IL5, IL6 and IL13 mRNA expression (P<0.05). DACT1 inhibited the expression and nuclear translocation of beta-catenin, while overexpression of beta-catenin significantly inhibited the biological function of DACT1 (P<0.05). Overexpression of beta-catenin also significantly suppressed the upregulation of IL5, IL6 and IL13 mRNA induced by pcDNA3.1-DACT1 transfection (P<0.05). Following the addition of Wnt5A, overexpression of DACT1 inhibited the expression and nuclear translocation of beta-catenin, and upregulated IL5, IL6 and IL13 mRNA expression. In conclusion, DACT1 was indicated to be upregulated in lung tissues from children with asthma, which could induce higher pro inflammatory factor expression. DACT1 may act via inhibiting the expression and nuclear translocation of beta-catenin, a factor in the Wnt signaling pathway. The present results suggested that DACT1 may be a potential target for the treatment of asthma. PMID- 29456670 TI - Effect of activated charcoal hemoperfusion on renal function in patients with paraquat poisoning. AB - The present study retrospectively analyzed 19 patients diagnosed with paraquat (PQ) poisoning with the aim to investigate the effect of activated charcoal hemoperfusion on renal function and PQ elimination. The results indicated that 7 patients died and 12 survived. Non-oliguric renal failure occurred in all of the 7 patients who died. Among the 12 surviving patients, 10 had normal renal function and 2 developed non-oliguric renal failure. There was a linear correlation between plasma and urine paraquat concentration prior to and during activated charcoal hemoperfusion. The equation parameters together with the correlation coefficient on admission were as follows: Y=0.5820+1.7348X (R2=0.678; F=35.768; P<0.0001). The equation parameters together with the correlation coefficient were as follows during activated charcoal hemoperfusion: Y=0.6827+1.2649X (R2=0.626; F=50.308; P<0.0001). Therefore, it was concluded that in patients with normal renal function, the elimination kinetics of PQ by the kidneys were only associated with the plasma PQ concentration. Activated charcoal hemoperfusion had little effect on avoiding acute kidney injury in patients with severe PQ poisoning. PMID- 29456671 TI - Current perspectives of SA-4-1BBL in immune modulation during cancer. AB - A recombinant co-stimulatory molecule capable of inducing multiple effects on varied immune cells when present in its soluble active form is termed as SA-4 1BBL. It has been reported to influence innate, adaptive, and regulatory immune cells. Recent studies confirmed its engagement with receptor, 4-1BB leading to collection of interleukin-2 (IL-2) that in turn overcomes Treg suppression. Further, a vast number of pre-clinical studies reported its therapeutic efficacy in the form of adjuvant subunit in cancer vaccines. Furthermore, it is also observed that it contributes significantly towards communication bridge of CD4 and NK cells. On the other hand, depletion of either NK or CD4 cells negated SA-4 1BBL's antitumor protection. The present review article is focused on the current updates of this molecule pertaining to the filed of cancer therapeutics or cancer preventives. PMID- 29456672 TI - Roles of autophagy in androgen-induced benign prostatic hyperplasia in castrated rats. AB - The present study investigated the role of androgen in the process of androgen induced prostate hyperplasia in castrated rats and assessed the role of the phosphoinositide 3-kinase/protein kinase B/mechanistic target of rapamycin (PI3K/Akt/mTOR) pathway in this process. Furthermore, the extent to which autophagy may affect the level of androgen-induced benign prostatic hyperplasia was also explored. A total of 40 Sprague Dawley rats were randomly divided into four groups: Testosterone group, rapamycin group, 3-methyladenine (3-MA) group, and control group. The extent of hyperplasia in prostate tissue the apoptosis and autophagy were assayed. The prostate wet weight, volume and index in the testosterone group were significantly higher compared with the control group (P<0.05) and these factors were significantly lower in the rapamycin group compared with the testosterone group (P<0.05). HE staining demonstrated that prostate hyperplasia was obvious in the testosterone group. Western blotting revealed that caspase-3 levels were higher in the 3-MA group compared with the control group and Bcl-2 was higher in the testosterone group compared with the control group (P<0.05). Furthermore, in the rapamycin group, Bcl-2 protein expression levels were significantly lower than those in the testosterone group (P<0.05). The prostate tissue was analyzed using electron microscopy and autophagy bodies were identified in the rapamycin group. In the process of androgen-induced prostatic hyperplasia in castrated rats, the role of androgen may be related to the PI3K/Akt/mTOR signaling pathway. Rapamycin was able to inhibit the effect of testosterone and promoted prostate tissue hyperplasia by inhibiting the PI3K/Akt pathway. In addition to inhibiting apoptosis in prostate cells, androgen was able to induce rat prostate hyperplasia and may also be related to the promotion of the proliferation of prostate cells. PMID- 29456673 TI - Full-thickness conjunctival flap covering surgery combined with amniotic membrane transplantation for severe fungal keratitis. AB - Fungal keratitis is a severe and common ocular infectious disease. The present study evaluated the efficiency of full-thickness conjunctival flap covering surgery with amniotic membrane transplantation (FCCS + AMT) as a transitional surgery for severe fungal keratitis. A total of 17 patients with severe fungal keratitis without corneal perforation underwent FCCS + AMT between January 2010 and December 2015. The pathogenic factors, preoperative diagnosis and postoperative prognosis of FCCS + AMT at 3 months were evaluated. Subsequently, 7 patients received sclerokeratoplasty, and the best-corrected visual acuity (BCVA) and recurrence ratio were analyzed at 1 month postoperatively. The primary risk factor was agricultural trauma (7 cases), followed by a non-agricultural object entering the eye (3 cases). Preoperatively, there were 10 cases of fungal keratitis positively identified using confocal microscopy and 9 cases positively identified by corneal scrapings. A total of 3 months following FCCS + AMT, the percentage of cases resulting in preservation of the eyeball was 88.24%, with 15/17 patients demonstrating complete conjunctival re-epithelization and a smooth conjunctival surface without any complications. A total of 2 (11.76%) patients experienced melting of the conjunctival flap and development of endophthalmitis, and subsequently underwent ocular evisceration surgery. A total of 7 patients underwent sclerokeratoplasty and the mean logarithm of the minimum angle of resolution BCVA at 1 month was significantly improved (0.689+/-0.121; P<0.001) compared with preoperative values (2.459+/-0.037) and BCVA values following FCCS + AMT (2.529+/-0.066). No recurrence was observed in any of the cases during the follow-up period. Conclusively, FCCS + AMT may be a preferable treatment for severe fungal keratitis of the entire corneal ulcer without perforation, and may save the eyeball and provide a greater opportunity for corneal transplantation. PMID- 29456674 TI - Inflammation responses in patients with pulmonary tuberculosis in an intensive care unit. AB - Pulmonary tuberculosis caused by Mycobacterium tuberculosis remains a global problem. Inflammatory responses are the primary characteristics of patients with pulmonary tuberculosis in intensive care units (ICU). The aim of the present study was to investigate the clinical importance of inflammatory cells and factors for patients with pulmonary tuberculosis in ICU. A total of 124 patients with pulmonary tuberculosis in ICU were recruited for the present study. The inflammatory responses in patients with pulmonary tuberculosis in ICU were examined by changes in inflammatory cells and factors in the serum. The results indicated that serum levels of lymphocytes, plasma cells, granulocytes and monocytes were increased in patients with pulmonary tuberculosis in ICU compared with healthy controls. The serum levels of inflammatory factors interleukin (IL) 1, IL-6, IL-10, IL-12, and IL-4 were upregulated in patients with pulmonary tuberculosis in ICU. Lower plasma concentrations of IL-2, IL-15 and interferon gamma were detected in patients with pulmonary tuberculosis compared with healthy controls. It was demonstrated that high mobility group box-1 protein expression levels were higher in the serum of patients with pulmonary tuberculosis compared with healthy controls. Notably, an imbalance of T-helper cell (Th)1/Th2 cytokines was observed in patients with pulmonary tuberculosis. Pulmonary tuberculosis caused by M. tuberculosis also upregulated expression of matrix metalloproteinase (MMP)-1 and MMP-9 in hPMCs. In conclusion, these outcomes demonstrated that inflammatory responses and inflammatory factors are associated with the progression of pulmonary tuberculosis, suggesting that inhibition of inflammatory responses and inflammatory factors may be beneficial for the treatment of patients with pulmonary tuberculosis in ICU. PMID- 29456675 TI - Correlation between PPAR-alpha methylation level in peripheral blood and atherosclerosis of NAFLD patients with DM. AB - We investigated the correlation between the methylation levels of peroxisome proliferator-activated receptor-alpha (PPAR-alpha) in the peripheral blood and atherosclerosis in patients with nonalcoholic fatty liver disease (NAFLD) with diabetes mellitus (DM). A total of 50 normal subjects (group N) and 50 NAFLD patients with DM (group M) were selected at Qilu Hospital of Shandong University. The levels of total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL) and low-density lipoprotein (LDL) in groups N and M were detected. The mRNA and protein expressions of PPAR-alpha in groups N and M were detected using reverse transcription polymerase chain reaction (PCR) and immunofluorescence. The differences in expression of PPAR-alpha in group N and M and the correlation between PPAR-alpha methylation level and atherosclerosis were analyzed using SPSS17.0 statistical software. TC, TG, HDL and LDL in groups N and M were significantly different (P<0.01). Hematoxylin and eosin staining showed that the histopathological damage was severe in group M. PCR and immunofluorescence showed that PPAR-alpha was significantly higher in N than in group M (P<0.01). The abnormal expression of PPAR-alpha is closely related to atherosclerosis, indicating that the correlation between PPAR-alpha methylation levels in peripheral blood and atherosclerosis of NAFLD patients with DM can provide a new direction of diagnosis and treatment. PMID- 29456676 TI - Cordyceps sinensis inhibits airway remodeling in rats with chronic obstructive pulmonary disease. AB - Cordyceps sinensis is a traditional Chinese herbal medicine that has been used for centuries in Asia as a tonic to soothe the lung for the treatment of respiratory diseases. The aim of the present study was to determine the effects of C. sinensis on airway remodeling in chronic obstructive pulmonary disease (COPD) and investigate the underlying molecular mechanisms. Rats with COPD were orally administered C. sinensis at low, moderate or high doses (2.5, 5 or 7.5 g/kg/day, respectively) for 12 weeks. Airway tissue histopathology, lung inflammation and airway remodeling were evaluated. C. sinensis treatment significantly ameliorated airway wall thickening, involving collagen deposition, airway wall fibrosis, smooth muscle hypertrophy and epithelial hyperplasia in model rats with COPD. Additionally, C. sinensis administration in rats with COPD reduced inflammatory cell accumulation and decreased inflammatory cytokine production, including tumor necrosis factor-alpha, interleukin-8 and transforming growth factor (TGF)-beta1 in bronchoalveolar lavage fluid. Meanwhile, the increased levels of alpha-smooth muscle actin and collagen I in the COPD group were also markedly decreased by C. sinensis treatment. Furthermore, compared with untreated rats with COPD, C. sinensis reduced the expression level of phosphorylated (p)-Smad2, p-Smad3, TGF-beta1 and its receptors, with the concomitant increased expression of Smad7 in the lungs of rats with COPD. These results indicated that treatment with C. sinensis may be a useful approach for COPD therapy. PMID- 29456677 TI - Concurrent eosinophilia and IgG4-related disease in a child: A case report and review of the literature. AB - The current study presents the case of a 9-year-old Chinese boy who presented with eosinophilia and elevated serum levels of immunoglobulin G4 (IgG4). A bone marrow puncture identified an elevated eosinophil rate of 23% (normal range, <5%), which indicated eosinophilia. However, gene analysis, fluorescent in situ hybridization and other examinations, including bone marrow aspiration, blood routine, auto-antibody tests and parasitic and allergens screening, contradicted a diagnosis of secondary or clonal eosinophilia. Furthermore, the patient exhibited multiple lymph node swelling and a lymph biopsy strongly indicted a pathological diagnosis of IgG4-related disease (IgG4-RD). His peripheral blood flow cytometry confirmed an elevated count of plasmablasts, which is specific to IgG4-RD. The patient responded well to therapy with prednisone and remained healthy in all follow-ups. By taking all these factors into consideration, the boy was diagnosed with IgG4-RD. It is difficult to distinguish IgG4-RD from hypereosinophilic syndrome and the potential association between the two remains unclear. However, the present case study serves as a reminder that IgG4-RD may occur in children and medical professionals should not neglect this possibility. PMID- 29456678 TI - Association between DSCR4 gene methylation in plasma in early pregnancy and Down's syndrome. AB - Down's syndrome (DS), a chromosomal abnormal genetic disease caused by a local or total copy of chromosome 21, leads to patients suffering from delayed body growth, special facies, mild to moderate mental retardation and other symptoms, seriously affecting the life of patients. The aim of the present study was to examine the association between Down's syndrome critical region 4 (DSCR4) gene methylation in plasma in high-risk pregnant women with DS in early pregnancy (hereinafter referred to as pregnant women in early pregnancy) and DS, in order to screen new epigenetic markers for the clinical diagnosis of DS. DNA in peripheral blood cells and plasma in pregnant women in early pregnancy were treated with hydrosulphite. DSCR4 genes with different methylation levels were amplified by methylation-specific polymerase chain reaction (PCR), and the methylation difference of the CpG site of the DSCR4 amplification product in peripheral blood DNA was verified via restriction endonuclease analysis. The expression of DSCR4 with different methylation levels in peripheral blood of pregnant women in early pregnancy were detected via reverse transcriptase quantitative PCR (RT-qPCR), and the DSCR4 gene functions were studied via the intervention in DSCR4 expression with small interfering RNA (siRNA). Methylation specific PCR and restriction endonuclease analysis revealed that DSCR4 genes were differentially methylated in peripheral blood DNA in pregnant women in early pregnancy. Additionally, DSCR4 showed a low methylation status in plasma but a high methylation status in peripheral blood cells. RT-qPCR revealed that non methylated DSCR4 was highly expressed in the peripheral blood of pregnant women in early pregnancy, and thus was an epigenetic marker of fetal DS. siRNA results showed that the downregulation of DSCR4 inhibited cell migration and invasion, but had no effect on cell proliferation. The results suggest that the DSCR4 gene was differentially methylated in peripheral blood DNA in pregnant women in early pregnancy. Furthermore, DSCR4 exists in a non-methylated state in plasma and in a hyper-methylated state in blood cells. DSCR4 can therefore promote the migration and invasion of trophocytes and serve as an epigenetic marker of non invasive clinical diagnosis of DS. PMID- 29456679 TI - miR-98 inhibits cell proliferation and induces cell apoptosis by targeting MAPK6 in HUVECs. AB - The aim of current study was to explore the role of microRNA (miR)-98 in atherosclerosis. Human vascular endothelial cells (HVECs) were isolated from the peripheral blood of healthy volunteers and patients with atherosclerosis. Compared with endothelial cells from the healthy control group, the expression level of mitogen activated protein kinase (MAPK)6 was significantly upregulated and miR-98 was downregulated in the endothelial cells of patients with atherosclerosis. The human umbilical vein endothelial cell line (HUVEC) was adopted to perform in vitro studies. Overexpression of miR-98 reduced the proliferation and induced the apoptosis of HUVECs, which were revealed using an MTT assay, and flow cytometry assay, respectively. The aforementioned influences of miR-98 on HUVECs were mediated by targeting MAPK6, which was verified using luciferase assays. Additionally, the overexpression of miR-98 reduced the protein level of apoptosis regulator Bcl-2 and MAPK6; however, it induced the protein expression of caspase-3 and apoptosis regulator Bax. In conclusion, these findings demonstrate that miR-98 is an important regulator of atherosclerosis, suggesting that miR-98 may be a potential therapeutic target for the treatment of atherosclerosis. PMID- 29456680 TI - Correlation of vitamin D receptor with bronchial asthma in children. AB - This study was designed to investigate the correlation of vitamin D receptor (VDR) gene polymorphism with bronchial asthma in children. Seventy patients admitted to Daqing Longnan Hospital and diagnosed as bronchial asthma for the first time from April 2015 to May 2017 were selected as observation group. Patients received routine treatment and intervention. Seventy healthy subjects admitted to hospital during the same period were enrolled as the control group. Vitamin D gene polymorphism was detected by polymerase chain reaction-restriction fragment length polymorphism assay; the levels of total serum immunoglobulin E (IgE) in the two groups were determined by electrochemiluminescence immunoassay; lung function levels in patients were measured using PowerCube (Germany) pulmonary function instrument before and after treatment, and the relationship between VDR gene polymorphism and lung function in children with bronchial asthma was analyzed. The difference in comparison of base frequency of rs1544410 locus of VDR gene had no statistical significance between the two groups (P>0.05). The locus CC frequency of rs7975232 of VDR gene in observation group was lower in the observation group than that in the control group (P<0.05); the locus AC and AA frequencies of rs7975232 of VDR gene were higher in the observation group than those in the control group (P<0.05). The level of vitamin D was lower in the observation group than that in the control group (P<0.05); the level of total serum IgE was higher in the observation group than that in the control group (P<0.05). The forced expiratory volume in 1 sec (FEV1), peak expiratory flow (PEF) and the ratio of FEV1 to forced vital capacity (FVC) in children with bronchial asthma in the observation group were higher after treatment than those before treatment (P<0.05). The correlation research displayed that VDR gene polymorphism was negatively correlated with lung function levels in children with bronchial asthma (P<0.05). The results showed that children with bronchial asthma are often accompanied by different degrees of changes in VDR gene polymorphism, which is negatively correlated with the severity of asthma, so vitamin D should be strengthened to ameliorate the prognosis of children. PMID- 29456681 TI - Analysis of related factors of surgical treatment effect on 215 patients with laryngeal cancer. AB - This study investigated the factors affecting the surgical treatment effect on patients with laryngeal cancer. The clinical data (including the sex, age, smoking index, drinking, primary tumor site, tumor (T) stage, lymph nodes (N) stage, tumor differentiation degree, tumor diameter, surgical method, lymph node metastasis and cervical lymph node dissection) of 215 patients with laryngeal cancer in The Central Hospital of Wuhan were analyzed retrospectively; the survival rate was calculated using the Kaplan-Meier method; log-rank test was used for single-factor analysis, while Cox proportional hazard regression model was used for multiple-factor analysis. The 215 patients were followed up after surgical treatment. The 1-, 3- and 5-year survival rates were 96.2, 78.0 and 72.5%, respectively. The results of single-factor analysis showed that the age, primary tumor site, tumor differentiation degree, T stage, N stage, smoking index, tumor diameter and lymph node metastasis had significant influence on the postoperative curative effect on patients (P<0.05), but the patient's age, drinking and surgical method had no correlation with the postoperative curative effect (P>0.05). Multiple-factor analysis revealed that the primary tumor site, T stage, N stage and lymph node metastasis were the independent risk factors affecting the surgical effect on patients with laryngeal cancer. The survival rate of laryngeal cancer is decreased with the increase of T stage and N stage. The survival rate of patients with supraglottic laryngeal cancer is higher than that of patients with glottic laryngeal cancer and subglottic laryngeal cancer, and the survival rate of patients with lymph node metastasis-positive laryngeal cancer is lower than that of patients with lymph node metastasis-negative laryngeal cancer.

AB - Identification of novel factors critical for epithelial to mesenchymal transition (EMT) and cancer initiating cell (CIC) formation may aid in the identification of novel therapeutics for the treatment of endometrial cancer. The present study demonstrated that L1 cell adhesion molecule (CAM) is critical for EMT and formation of CICs in endometrial cancer. Overexpression of L1CAM may promote EMT with increased formation of CICs in HEC-1A endometrial cancer cells. CICs and mesenchymal status resist chemotherapeutic drugs and may regenerate the various cell types in tumors, thereby resulting in relapse of the disease. The present study demonstrated that overexpressing L1CAM promoted paclitaxel resistance and regulated paclitaxel resistance-associated microRNA expression in HEC-1A cells. Furthermore, it was demonstrated that overexpressing L1CAM promoted anoikis resistance in HEC-1A cells. This link between L1CAM and EMT/CICs may provide a novel target for advancing anticancer therapy.

AB - The aim of the present study was to explore the effects of pannexin1 (Px1) protein channels on osteogenic differentiation of mesenchymal stem cells (MSCs) under mechanical stress stimulation. MSCs were isolated from Sprague Dawley rats (3 weeks old, weighing 100-120 g) and cultured in vitro. A safe concentration of carbenoxolone was determined (CBX, an inhibitor of Px1 channels; 100 uM) on MSCs using the Cell Counting Kit-8 (CCK8) method. MSCs were divided into 6 groups: Control, stress (4,000 u strain), and stress following 3, 6, 12, and 24 h pretreatment with CBX. Stress groups were stimulated with mechanical stress for 15 min. Alkaline phosphatase (ALP) activity, type I collagen expression, intracellular calcium ion (Ca2+) concentration, Px1 expression, p38 mitogen activated protein kinase (MAPK) and extracellular signal-regulated phosphorylation were determined. ALP activity was increased in the stress group, and this was prevented by pretreatment with CBX. Similarly, stress-induced increases in type I collagen expression, Ca2+ concentration, Px1 expression, and p38 MAPK phosphorylation decreased in the presence of CBX. ERK phosphorylation was decreased by stress, however was not affected by CBX treatment. Altogether, the results suggest that mechanical stress promoted the osteogenic differentiation of MSCs, and this promotion was inhibited by pretreatment with CBX, possibly through regulating the phosphorylation of p38 MAPK. PMID- 29456684 TI - CAPN3, DCT, MLANA and TYRP1 are overexpressed in skin of vitiligo vulgaris Mexican patients. AB - Vitiligo is a disorder causing skin depigmentation, in which several factors have been proposed for its pathogenesis: Environmental, genetic and biological aspects of melanocytes, even those of the surrounding keratinocytes. However, the lack of understanding of the mechanisms has complicated the task of predicting the development and progression. The present study used microarray analysis to characterize the transcriptional profile of skin from Vitiligo Vulgaris (VV) patients and the identified transcripts were validated using targeted high throughput RNA sequencing in a broader set of patients. For microarrays, mRNA was taken from 20 skin biopsies of 10 patients with VV (pigmented and depigmented skin biopsy of each), and 5 biopsies of healthy subjects matched for age and sex were used as a control. A signature was identified that contains the expression pattern of 722 genes between depigmented vitiligo skin vs. healthy control, 1,108 between the pigmented skin of vitiligo vs. healthy controls and 1,927 between pigmented skin, depigmented vitiligo and healthy controls (P<0.05; false discovery rate, <0.1). When comparing the pigmented and depigmented skin of patients with vitiligo, which reflects the real difference between both skin types, 5 differentially expressed genes were identified and further validated in 45 additional VV patients by RNA sequencing. This analysis showed significantly higher RNA levels of calpain-3, dopachrome tautomerase, melan-A and tyrosinase related protein-1 genes. The data revealed that the pigmented skin of vitiligo is already affected at the level of gene expression and that the main differences between pigmented and non-pigmented skin are explained by the expression of genes associated with pigment metabolism.

AB - MicroRNAs (miRs) have previously been demonstrated to be important in the tumorigenesis and progression of breast cancer. miR-372 was previously revealed to be involved in various types of human cancer, however its function in breast cancer remains largely unknown. The present study demonstrated that miR-372 is frequently overexpressed in breast cancer cell lines and tissues. The downregulation of miR-372 markedly inhibited cell proliferation, arrested the cell cycle in the G1/S phase, and increased the apoptosis of breast cancer cells. Consistently, an in vivo xenograft study also demonstrated the suppressive effects of miR-372 knockdown on tumor growth. Further studies revealed that miR 372 modulated the expression of large tumor suppressor kinase 2 (LATS2) by directly targeting its 3'-untranslated region in breast cancer cells. Furthermore, silencing of LATS2 was able to rescue the effect of the miR-372 inhibitor. Overall, the results suggest that miR-372 functions as an oncogenic miRNA in breast cancer by targeting LATS2. PMID- 29456686 TI - Biochanin A extirpates the epithelial-mesenchymal transition in a human lung cancer. AB - The natural iso-flavonoid, biochanin A, is categorized as a phytoestrogen and has been demonstrated to exhibit various pharmacological properties. However, no effects of biochanin A on lung cancer cell lines have been reported. Therefore, the present study aimed to demonstrate whether biochanin A has the ability to reduce lung cancer triggered pro-inflammatory effects from leukemic monocytes. We studied the release of cytokines, tumor necrosis factor (TNF)-alpha and interleukin (IL)-6, from the cocultured cells of A427:AML-193. In addition to this, epithelial-mesenchymal transition was also monitored. In the cocultured A427 and AML-193, AML-193 was stimulated by A427 cells assisting the release of TNF-alpha and IL-6 cytokines, but the addition of A427 with biochanin A reduced A427-triggered generation of cytokines by AML-193. Moreover, this non-functional A427:AML-193 coculture reduced the metastasis effects of A427 cells, as determined by wound healing assays and migration/invasion assays. These results were further confirmed by a reduction in Snail and E-cadherin expression levels, which are indicators of the epithelial-mesenchymal transition. These findings suggest the therapeutic effect of biochanin A against lung cancer evoked inflammation and pro-inflammatory functions from monocytic cells. PMID- 29456687 TI - Girdin protein: A potential metastasis predictor associated with prognosis in lung cancer. AB - The present study explored the relationship between Girdin protein expression and the survival rate of patients with lung carcinoma. A total of 334 lung cancer specimens, 20 benign lung disease tissue sections and 24 fresh tissues from patients with lung carcinoma were analyzed by immunohistochemistry and western blotting. Girdin protein was expressed in 130/334 (38.93%) of the cases examined. Girdin protein expression was correlated with tumor/node/metastasis stage (P<0.001), lymph node metastasis (P=0.001), distant metastasis (P<0.001) and specimen sites (P=0.034). Girdin expression was also correlated with signal transducer and activator of transcription 3 (STAT3) expression (P<0.001). Patients with high Girdin and STAT3 expression had a significantly poorer prognosis compared with those with low/high, high/low or low/low expression (P<0.001). In summary, Girdin may be a prognostic marker of lung cancer and serve as a biomarker for metastasis. PMID- 29456688 TI - Overexpression of microRNA-506-3p aggravates the injury of vascular endothelial cells in patients with hypertension by downregulating Beclin1 expression. AB - The aim of the present study was to measure the expression of microRNA (miRNA) 506-3p in the peripheral blood of patients with hypertension and to determine the biological functions and mechanisms of action of miR-506-3p. A total of 61 patients with primary hypertension were included in the present study. Peripheral blood was collected from all patients, as well as 31 healthy subjects who were included in a control group. The expression of miR-506-3p in peripheral blood was determined by reverse transcription-quantitative polymerase chain reaction. Human umbilical vein endothelial cells (HUVECs) were transfected with miR-506-3p mimics or miR-506-3p inhibitor. The proliferation and migration of HUVECs were determined using cell-counting kit 8 and Transwell assays, respectively. The cell cycle and apoptosis of HUVECs were detected by flow cytometry. The expression of Beclin1 (BECN1) protein, a potential target of miR-506-3p, was measured using western blotting. A dual-luciferase reporter assay was performed to determine the interaction between BECN1 and miR-506-3p. It was demonstrated that miR-506-3p expression in the peripheral blood of patients with patients was upregulated and dependent on the severity of hypertension. miR-506-3p overexpression inhibited the proliferation and migration of HUVECs. In addition, miR-506-3p inhibited the transition from the G1 phase to the S-phase in HUVECs. Overexpression of miR-506 3p promoted the apoptosis of HUVECs. Notably, miR-506-3p downregulated the expression of BECN1 by directly binding to its 3'-untranslated region. The present study demonstrated that miR-506-3p expression is elevated in the peripheral blood of patients with hypertension and is associated with the severity of hypertension. By downregulating BECN1 expression, miR-506-3p aggravates injury in vascular endothelial cells by inhibiting the proliferation and migration of HUVECs, as well as promoting their apoptosis. PMID- 29456689 TI - Inhibition of the Ras/Raf/extracellular signal-regulated kinase 1/2 signaling pathway by compounds of natural origin for possible treatment of spinal cord injury: An in silico approach. AB - Spinal cord injury (SCI) is a severe disease associated with permanent neurological deficit. Recent studies in the treatment of SCI have demonstrated that the Ras/Raf/extracellular signal-regulated kinase 1/2 (ERK1/2) signaling pathway serves an important role in the disease etiology, and that upregulation of this signaling pathway is associated with the development of SCI. In the present study, inhibition of Ras protein was employed in order to downregulate the Ras/Raf/ERK1/2 signaling pathway using compounds of natural origin from the Interbioscreen natural compound database. To the best of our knowledge, this is the first study using a chemical-computational approach in order to identify novel small molecule inhibitors for Ras. A database of ~50,000 compounds was selected for virtual screening, setting a free energy binding bias of -7 kcal/mol to limit the number of compounds. The subset of compounds generated by virtual screening was further limited by subjecting these to the Lipinski's rule of five parameters. A total of five shortlisted compounds were subjected to molecular docking simulation. The compounds were docked into the GTP binding site of Ras, and the inhibition of this site was examined as a promising strategy for the downregulation of Ras/Raf/ERK1/2 signaling pathway. The compounds bound to the GTP binding site through hydrogen bonds and hydrophobic interactions. The identified lead compound was then subjected to molecular dynamics simulation, and the results revealed that GLY60 in the GTP binding site of Ras protein was the optimal binding site during a 100 nsec run. PMID- 29456690 TI - Protective effects of recombinant human brain natriuretic peptide in perioperative period during open heart surgery. AB - The aim of the present study was to evaluate the protective effects and safety aspects of recombinant human brain natriuretic peptide (rhBNP) on cardiac functions of patients undergoing open-heart surgery during perioperative period. In total, 150 patients undergoing open heart surgery in the Second Hospital of Shandong Universty from August 2015 to July 2016 were randomly divided into control group and observation group each with 75 cases. Patients in control group were treated by routine rehabilitation while patients in the observation group were treated by both the routine rehabilitation and rhBNP. All the observations were made before operation, after operation and 7 days after operation. The changes of N-terminal pro-brain natriuretic peptide (NT-proBNP) of patients, the left ventricular ejection fraction (LVEF), cardiac function [Cardiac output (CO), pulmonary capillary wedge pressure (PAWP) and central venous pressure (CVP)] of patients were measured. Further, respirator support time, ICU stay time, incidence of complications and vital signs (BP, HR, SaO2) of patients in the two groups were also compared. NT-proBNP levels of all patients improved after operation but it decreased in both groups after 7 days of operation. The decrease of NT-proBNP levels in observation group was significantly higher than that of control group. Whereas, LVEF, CO, PAWP and CVP of patients in both the groups increased after operation but effects were significantly higher in the observation group after 7 days of medication. Respirator support time and ICU stay time of patients in observation group were significantly shorter than those in control group, and the incidence of postoperative complications of patients in the observation group were significantly lower than the control group. Moreover, BP, HR and SaO2 of patients in observation group were significantly elevated in comparison to control group (P<0.05). Recombinant human brain natriuretic peptide (rhBNP) could significantly improve the cardiac functions of patients after open heart surgery, and is safe as well as reliable. PMID- 29456691 TI - Different doses of folic acid and vitamin B12 to treat rabbits with deep venous thrombosis and hyperhomocysteinemia. AB - The effects of different doses of folic acid and vitamin B12 on rabbits with deep vein thrombosis (DVT) and hyperhomocysteinemia were investigated. In total, 60 New Zealand rabbits were divided into untreated control, low-dose and high-dose groups. After inducing DVT, hemorheology and coagulation indexes were measured 3 and 10 days later. We found that both treatment groups performed better than the control group, and the high-dose performed better than the low-dose. Ten days after thrombosis, the levels of Hcy and D-dimer were lower in the high-dose group. Moreover, the changes of lower extremity deep venous thrombosis were significantly reduced in both high- and low-dose groups, but the high-dose group showed the most improvement. The effective rate of the high-dose group was 100%, higher than the rate in the low-dose and control groups. Overall, high-dose of folic acid and vitamin B12 can significantly improve plasma Hcy, coagulation indexes, and pathological changes in the venous thrombosis of the lower extremity. PMID- 29456692 TI - Effects of Th17/Treg cell imbalance on HIV replication in patients with AIDS complicated with tuberculosis. AB - The purpose of this study was to determine the effect of Th17/Treg cell imbalance on HIV replication in patients with AIDS complicated with tuberculosis (TB). We selected 32 patients with AIDS combined with TB infection in our hospital and 30 healthy individual as controls. The Th17/Treg ratio in peripheral blood lymphocytes was detected by flow cytometry. Compared with healthy subjects, Th17 cells first declined in HIV patients with TB, but gradually increased over the course of the disease. Treg showed an increasing trend in HIV patients with TB. The Th17/Treg ratio was significantly altered as the condition gradually deteriorated. ELISA showed that interleukin (IL)-17, IL-6 and IL-10 in patients with HIV complicated with TB were significantly lower than in healthy subjects. The imbalance of Th17/Treg cells can promote HIV virus replication in AIDS patients with TB infection, which can aggravate the condition. PMID- 29456693 TI - Seminal bacterial composition in patients with obstructive and non-obstructive azoospermia. AB - A number of culture-dependent and -independent studies have reported that the number and significance of bacterial species in semen may have been underestimated. The aim of the present study was to profile the seminal microbiome in patients with obstructive or non-obstructive azoospermia. A high throughput sequencing method was adopted to sequence genomic DNA extracted from the semen of healthy people (C group), patients with obstructive azoospermia (OA group) and patients with non-obstructive azoospermia (NOA group). The results revealed that Firmicutes, Proteobacteria, Bacteroidetes and Actinobacteria species comprised the majority of bacteria in the C (98.14%), OA (98.26%) and NOA (90.96%) groups. Patients in the OA and NOA groups exhibited an increase in Bacteroidetes and Firmicutes, whereas the number of Proteobacteria and Actinobacteria were decreased compared with the C group. A total of 398 common operational taxonomic units were identified, of which 27 belonged to the genus Lactobacillus. Furthermore, Phylogenetic Investigation of Communities by Reconstruction of Unobserved States analysis indicated that the pathogenic species and reduced biodiversity in the semen of patients with azoospermia may result in an increased risk of metabolic, infectious and immune diseases. In the present study, the seminal microbiome of patients with obstructive or non obstructive azoospermia was explored, which may be useful for developing novel treatments against azoospermia as well as for its diagnosis. PMID- 29456694 TI - Correlation of expression levels of caspase-3 and Bcl-2 in alveolar lavage fluid in neonatal respiratory distress syndrome and prognosis. AB - This study was designed to investigate the correlation between expression levels of cysteine aspartic protease-3 (caspase-3) and B-cell lymphoma gene-2 (Bcl-2) proteins in alveolar lavage fluid and the prognosis of infants with neonatal respiratory distress syndrome (RDS). A total of 150 infants with neonatal RDS undergoing alveolar lavages were divided into four groups: RDS1 (group A, n=42), RDS2 (group B, n=38), RDS3 (group C, n=38) and RDS4 (group D, n=32) according to their thoracic X-ray film grading. The oxygen uptake score, oxygenation saturation, mean airway pressure and expression levels of caspase-3 and Bcl-2 in alveolar lavage fluid of the infants in the four groups were measured and compared. Our results showed higher grading by thoracic X-rays in patients with increased oxygen uptake score, oxygenation index, mean airway pressure, caspase-3 expression level, hospital stay, complications and death rates in all groups; however, the expression levels of Bcl-2 were decreased in those cases, and the differences had statistical significance among the four groups (P<0.05). Analyses for correlation showed a caspase-3 positive area that was positively correlated with oxygen uptake score, oxygenation index and mean airway pressure (P<0.05); and a Bcl-2 expression level that was negatively correlated with oxygen uptake score, oxygenation index and mean airway pressure (P<0.05). Based on our findings, the severity of neonatal RDS is positively correlated with the concentration of caspase-3 in alveolar lavage fluid, and negatively correlated with the expression level of Bcl-2. PMID- 29456695 TI - A comparative study of the single-site laparoscopic herniorrhaphy using needle instruments and double-site laparoscopic herniorrhaphy in the minimally invasive treatment of inguinal hernias in children. AB - The clinical effect of the single-site laparoscopic herniorrhaphy (SSLH) using needle instruments and double-site laparoscopic herniorrhaphy (DSLH) in the treatment of inguinal hernias in children were compared. A total of 1,010 children with inguinal hernias who were treated in Chao-Yang Hospital from March 2011 to December 2014 were selected. According to the operation method, these children were divided into the single-site group using needle instruments (n=508) and the traditional double-site group (n=502). The clinical indexes of the two groups were compared. All the clinical indexes (operation time, intraoperative blood loss, time of off-bed and discharge time) in the single-site group using needle instruments were significantly lower than those in the traditional double site group (P<0.001, <0.001, <0.001 and <0.003, respectively), but the incidence rates of postoperative complications and contralateral occult hernia were at the similar level (P=0.249 and 0.221, respectively), so the difference was statistically insignificant. Patients in the two groups were followed up for 2 years and there was no recurrece in children in the single-site group while there was 2 in the double-site group. The SSLH using needle instruments is more effective with fewer traumas in the treatment of inguinal hernias in children than the DSLH. It is easier for children to recover from the herniorrhaphy with no scars, so it conforms more closely to the concept of minimally invasive herniorrhaphy, which can be promoted and applied for the treatment of inguinal hernias in children. PMID- 29456696 TI - Infectious mononucleosis and hepatic function. AB - Abnormal hepatic function is common in infectious mononucleosis (IM). However, it remains unknown why increased transferase levels are more common than bilirubin abnormalities in IM. The current study aimed to investigate these associations in the Chinese population. A total of 95 patients with IM (47 males and 48 females) were enrolled in the current study, as well as 95 healthy controls. Patients were sorted by sex. A receiver operating characteristic (ROC) curve was used to determine cut-off values for IM diagnosis and prediction. Crude and adjusted odds ratios (OR) for IM were analyzed using binary logistic regression. It was determined that alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma-glutamyl transferase (GGT) levels were significantly higher in patients with IM compared with controls; however, total bilirubin (TB) levels were significantly lower in patients with IM. ROCs demonstrated that, if ALT, AST and GGT concentrations were higher than, or if TB was lower than, cut-off values, they were predictive of IM. Binary logistic regression identified that the risk of IM in patients exhibiting high levels of transferases was significantly increased, particularly in males. Crude ORs in ALT quartile 4 were 21.667 and 10.111 for males and females, respectively and adjusted ORs were 38.054 and 9.882, respectively. A significant IM risk of IM was evident in patients with low bilirubin levels and females appeared to be particularly susceptible. For example, crude ORs in quartile 1 were 8.229 and 8.257 for males and females, respectively and adjusted ORs were 8.883 and 10.048, respectively. Therefore, the current study identified a positive association between transferase levels and IM and a negative association between TB and IM. Therefore, the results of the current study indicate that high transferases are suggestive of IM, particularly in males, whereas low TB is suggestive for IM, particularly in females. PMID- 29456697 TI - Relationship between fat mass and obesity-associated gene expression and type 2 diabetes mellitus severity. AB - This study sought to investigate any correlation between fat mass and obesity associated gene (FTO) expression and the severity of type 2 diabetes mellitus (T2DM). In total 110 patients newly diagnosed with T2DM in the outpatient department of Yantai Yuhuangding Hospital between September 2016 and March 2017 were selected as study subjects and were divided into severe (58 cases) and mild groups (52 cases) according to T2DM severity. Patients in the severe group were followed up for 12 weeks. An additional 60 healthy individuals were selected to serve as the normal control group. Fasting plasma glucose (FPG), fasting insulin (FINs), fasting C-peptide (FCP), glycosylated hemoglobin (HbA1c) and homeostasis model assessment of insulin resistance (HOMA-IR) were examined for every patient in the study. Real-time polymerase chain reaction (RT-PCR) was used to detect FTO messenger ribonucleic acid (mRNA) expression levels in patient peripheral blood lymphocytes. Western blotting was used to detect serum FTO protein expression levels, upon which the correlation between FTO protein levels and all other indices were analyzed. Compared with the normal control group, both T2DM groups showed significantly increased waist circumferences, hip circumferences, body mass indexes (BMIs), blood glucose indexes (FPG, FCP, HbA1c, FINs, HOMA-IR) and FTO mRNA/protein levels (p<0.05). Additionally, the increases presented by the severe T2DM group were significantly greater than those presented by the mild T2DM group (p<0.05). After 12 weeks of treatment, the severe T2DM group showed decreased BMI, blood glucose index and FTO protein expression (p<0.05). FTO protein expression in T2DM patients was higher than in healthy controls, with severe patients showing greater expression levels than mild group patients. FTO expression was positively correlated with BMI, waist circumference, chest circumference, FPG, FCP, HbA1c, FINs and HOMA-IR. Therefore, FTO expression can serve as a marker for the clinical diagnosis and treatment of T2DM. PMID- 29456698 TI - Correlation of blood glucose, serum chemerin and insulin resistance with NAFLD in patients with type 2 diabetes mellitus. AB - Non-alcoholic fatty liver disease (NAFLD) is a form of clinical syndrome characterized by the fatty degeneration in liver histology and should be further investigated. The aim of the study was to investigate the effects of blood glucose, serum chemerin and insulin resistance on non-alcoholic fatty liver disease (NAFLD) in patients with type 2 diabetes mellitus to provide a basis for the prevention and treatment thereof. In total, 300 patients with type 2 diabetes mellitus treated and admitted into the Endocrinology Department of our hospital from June 2015 to June 2017 were enrolled and divided into the simple type 2 diabetes mellitus (group A) and concurrent NAFLD (group B) groups. The sex, age, body mass index (BMI), blood pressure, blood biochemical indexes and chemerin level were compared between the two groups. The patients in group B were further divided into the mild fatty liver (group B1), moderate fatty liver (group B2) and severe fatty liver (group B3) groups. The sex, age, BMI blood pressure, blood biochemical indexes and chemerin level were also compared among the three groups. Finally, the risk factors of type 2 diabetes mellitus complicated by NAFLD were analyzed via logistic regression. The BMI, fasting plasma glucose (FPG), 2 h post prandial plasma glucose (2hPG), triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-c), alanine aminotransferase (ALT), fasting insulin (FINS), homeostasis model assessment of insulin resistance (HOMA-IR) and HOMA-beta indexes and serum chemerin level in group B were significantly higher than those in group A (P<0.05 or P<0.01). Notably, the aggravation of NAFLD, the aforementioned indexes were obviously increased (P<0.05 or P<0.01). The regression analysis revealed that BMI, FPG, TC, LDL-c, FINS, HOMA-IR and chemerin were risk factors of concurrent NAFLD. Thus, type 2 diabetes mellitus complicated by NAFLD is closely associated with severe glucose-lipid metabolism disorder and insulin resistance, and BMI, FPG, TC, LDL-c, FINS, HOMA-IR and chemerin constitute risk factors of concurrent NAFLD. PMID- 29456699 TI - Correlation between survivin polymorphism and acute leukemia of children. AB - The correlation between the variations in the polymorphic sites of survivin, rs9904341C/G and rs8073069C/G, and the pathogenesis of acute leukemia, as well as the guiding significance in clinical practice were investigated. We enrolled a total of 182 children with acute leukemia and 200 healthy children as the subjects. In accordance with the case-control method, the polymerase chain reaction was carried out for genetic typing of the two polymorphic sites, rs9904341C/G and rs8073069C/G. In the case group and the healthy group, the frequencies of C and G alleles in rs9904341C/G of survivin were 59.3 and 41.7%, and 46.7 and 50.3%, respectively, and the pairwise comparison showed statistically significant differences (P=0.008). Additionally, the frequencies of genotypes, C/C, C/G and G/G, were 38.5 and 41.7%; 19.8 and 26.5%; 16.5 and 27.0% in the case group and the healthy group, respectively, and the differences in comparisons showed statistical significance (P=0.033). The genotype frequency of C/C in the case group was 38.5%, significantly higher than that in the healthy group (26.5%). Compared with C/C, the risk coefficient of leukemia in patients with genotypes of C/G or G/G was significantly decreased. In the case group and the healthy group, the frequencies of C and G alleles in rs8073069C/G of survivin were 30.5 and 69.5%; 27.7 and 72.3%, respectively, and the pairwise comparison showed no statistically significant differences (P=0.404). Additionally, the frequencies of genotypes, C/C, C/G and G/G, were 11 and 39.0%; 50.0 and 9.0%; 37.5 and 53.5% in the case group and the healthy group, respectively, and the differences in comparisons showed no statistical significance (P=0.62). Compared with the genotype of C/C, we found that the risk of leukemia was not affected in patients with genotypes of C/G and G/G. In conclusion, the SNP of rs9904341C/G in survivin may be correlated with the risk of acute leukemia, and compared with C/C genotype, patients with C/G or G/G may have a decreased risk of acute leukemia. In survivin, rs8073069C/G may have no correlation with the risk of acute leukemia. PMID- 29456700 TI - Effects of HIV on metabolic and biological pathways of CD4+ T lymphocytes. AB - The effects of human immunodeficiency virus (HIV) on the metabolic and biological pathways of cluster of differentiation (CD)4+ T lymphocytes were investigated. A total of 150 patients with acquired immune deficiency syndrome (AIDS) and 50 healthy individuals who were admitted to hospital for physical examination during the period of June 2016 to January 2017, were selected as subjects in the present study. According to the virus load, 150 AIDS patients were divided into three groups: i) Viral load >106 copies/ml (group A, n=39), ii) 104 copies/ml < viral load <105 copies/ml (group B, n=76), and iii) viral load <104 copies/ml (group C, n=35). The relationship between viral loads in the three groups and CD4+ T lymphocyte counts was assessed. Active lymphocytes were isolated from T lymphocytes in the subjects, and the ratio of Th1 to Th2 was measured by flow cytometry. Effects of HIV on human T-lymphocyte differentiation were observed. Differences in T-lymphocyte metabolites were detected by proton nuclear magnetic resonance and their biological pathways analyzed. The results showed that CD4+ T cell counts were decreased with the increase of the viral loads of patients. The viral loads of AIDS patients differentiated T lymphocytes. In other words, high viral loads accelerated the differentiation of T lymphocytes into Th1 cells. In the high HIV viral load group, the levels of glycerol phosphodiesterase, 7 dehydrocholesterol, p-hydroxyphenylacetic acid, cholesterol and deoxyuridine were increased, but the levels of 3-methoxytyramine, cytidine deaminase, deoxycorticosterone and 3-hydroxybutyric acid were decreased. The viral loads of AIDS patients are associated with CD4+ T-cell counts and the ratio of CD4+ T to CD8+ T cells. At the same time, HIV viral loads can affect the lipid biosynthesis of T-lymphocyte membranes, thus affecting the differentiation and proliferation of T lymphocytes and finally intervening its mediated immune responses. PMID- 29456701 TI - Correlation between cortisol levels and concurrent infection for hepatitis B cirrhosis patients and countermeasure analysis. AB - The study assessed the correlation between cortisol (COR) levels and concurrent infection for the patients with hepatitis B cirrhosis for corresponding countermeasure analysis. In total, 86 patients with hepatitis B cirrhosis (non infection group) and 32 patients with hepatitis B cirrhosis complicated with infection (infection group) who were diagnosed and treated in the Beijing YouAn Hospital from March 2014 to March 2017 were selected. The fasting venous blood of all the patients was drawn to detect COR, cortisol binding globulin (CBG), blood routine indexes, C-reactive protein (CRP), procalcitonin (PCT), endotoxin and other indicators. The relative expression of CBG mRNA was detected by reverse transcription quantitative polymerase chain reaction (RT-qPCR). The differences and correlation of COR levels between the infection and non-infection groups were compared and analyzed. The concentrations of COR and CBG were decreased with the increase of Child-Pugh grade, and the difference was statistically significant (P<0.05). COR, CBG and free cortisol (FC) concentrations with the same Child-Pugh grade in the non-infection group were higher than those in the infection group (P<0.05). COR, CBG and FC concentrations of abdominal infection complicated with sepsis or abdominal infection complicated with pulmonary infection were lower than those of simple abdominal infection (P<0.05). The relative expression of CBG mRNA was detected by RT-qPCR, which also showed that: for Child-Pugh grade, grade A > grade B > grade C (P<0.05), non-infection group > infection group (P<0.05), abdominal infection + sepsis group and abdominal infection + pulmonary infection group were lower than the simple abdominal infection group (P<0.05). The values of white blood cells (WBC), neutrophils, CRP, PCT and endotoxin in the infection group were higher than those in the non-infection group, and the differences were statistically significant (P<0.05). COR, CGB and FC were negatively correlated with inflammatory indexes such as WBC, neutrophils, CRP, PCT and endotoxin. The r value of COR and FC in the non-infection group was 0.678, while that of OR and FC in the infection group was 0.787. COR was positively correlated with FC before and after infection. The results of the study show that the cortisol levels of patients with hepatitis B cirrhosis are significantly correlated with whether infected or not, levels of disease condition and infection types, and can be used as sensitive indicators of hepatitis B cirrhosis infection.

AB - This study observed the clinical efficacy of pre-injection of dexmedetomidine of different doses before surgery and the adverse reactions during the recovery period in pediatric intravenous general anesthesia without tracheal intubation. Pediatric patients who received general anesthesia without tracheal intubation before surgery from January 2016 to March 2017 were randomly divided into four groups (n=30), and were respectively treated with intravenous pump infusion of loaded dexmedetomidine of high-dose (2.5 ug/kg), middle-dose (1.5 ug/kg) and low dose (0.5 ug/kg), while the children in the control group received injection of normal saline in same dose. Then, the mean arterial pressure (MAP) at different time points (5 and 10 min after administration, after anesthesia and after surgery), heart rate, Ramsay sedation score changes and adverse reactions during recovery period of anesthesia of pediatric patients were compared among four groups. At 5 and 10 min after administration, Ramsay scores of high-dose group and middle-dose group were higher than that of the control group, and the differences had statistical significance (P<0.05). There was no significant difference in comparison of Ramsay scores between low-dose group and the control group. The MAP and heart rate after anesthesia and after surgery of pediatric patients with pump infusion of dexmedetomidine in the three groups were decreased significantly compared to those of the control group, and the differences had statistical significance (P<0.05). The incidence rate of adverse reaction of pediatric patients during the recovery period after pump infusion in the three groups and the control group was, respectively, 13/30, 8/30, 7/30 and 8/30, and the differences were statistically significant (P<0.05). The sedative effect and safety of pre-injection of dexmedetomidine in pediatric intravenous general anesthesia without tracheal intubation are promising, and the medium dosage can maximize the anesthetic effect with less side effects. PMID- 29456703 TI - Silencing of TGIF sensitizes MDA-MB-231 human breast cancer cells to cisplatin induced apoptosis. AB - The present study was designed to explore the sensitivity of MDA-MB-231 cells to cisplatin after silencing the expression of TG-interacting factor (TGIF) protein. Cell viability was measured using an MTT assay. Cell apoptosis was detected by the annexin V and dead cell assay and the Hoechst staining assay. Protein expression was analyzed using western blot analysis. A colony formation assay was also performed. It was observed that cisplatin reduced the expression of TGIF protein in a dose- and time-dependent manner. Silencing TGIF significantly suppressed the cell proliferation and colony formation in MDA-MB-231 cells with the treatment of cisplatin. Results indicated that silencing TGIF could dramatically increase the cisplatin-induced apoptosis rate in MDA-MB-231 cells. The expression of PARP and caspase-3 proteins was correlated with the effect that silencing TGIF enhanced cisplatin sensitivity in MDA-MB-231 cells. The present data showed that silencing TGIF promoted apoptotic sensitivity that was induced by cisplatin in MDA-MB-231 human breast cancer cells and suggested that TGIF might be a therapeutic target for improving the chemotherapy response in triple negative breast cancer. PMID- 29456704 TI - Optimal method of gold nanoparticle administration in melanoma-bearing mice. AB - The present study assessed different methods of administering gold nanoparticles (GNPs) using different formulations to determine which of the methods achieved optimal radiosensitization. Cells from the B16F10 mouse melanoma cell line were implanted in the femoral area of mice, assigned to one of the eight following groups: i) Control; ii) intravenous (IV) injection of polyethylene glycol (PEG) binding GNPs (Peg-GNPs) alone; iii) direct intratumoral (IT) injection of Peg GNPs alone; iv) radiotherapy (RT)-alone; v) Peg-GNP IV + RT; vi) Peg-GNP IT + RT; vii) naked GNP (N-GNPs) IV + RT; and viii) N-GNP IT + RT. Injection volumes of the Peg-GNPs (particle size, 15 nm; dose, 2.8 mg/ml) and N-GNPs (particle size, 15 nm; dose, 200 mg Au/cc) were 0.3 and 0.2 ml per mouse, respectively, for IV and IT. The femoral area was irradiated with a single dose of 10 Gy. To evaluate the effects of GNPs, the current study measured the changes in the tumor volume ratio to the initial tumor volume over time and observed the survival rate. Administration of GNPs with RT did not improve the suppression of tumor growth or survival to a statistically significant extent. The administration of Peg-GNPs alone indicated a slight tumor suppressing effect at the early stage. The current study was not able to confirm the radiosensitization effect of GNPs in melanoma bearing mice with tumors that were large in comparison to previous studies. Further research is required to validate the radiosensitizing effect on large tumors. PMID- 29456705 TI - Discrimination of malignant transformation from benign endometriosis using a near infrared approach. AB - The aim of the present single-center retrospective study was to investigate the discrimination of malignant transformation from ovarian endometrioma (OE) using a near-infrared approach ex vivo. Cystic fluid samples were collected from patients with OE (n=34) and endometriosis-associated ovarian cancer (EAOC) (n=12). The light reflected from each sample of cystic fluid [change in luminance, Deltal (cd/m2) = background luminance-cystic fluid luminance at 800 nm] was spectrally measured by a near-infrared CCD camera with band-path filter (800 nm). The Deltal in EAOC was significantly lower compared with that in OE. On regression analysis, a positive correlation was observed between the Deltal and Hb level in the cystic fluid, and this association was exponential. The diagnostic sensitivity and specificity of Deltal was 83.3 and 94.1% at the cutoff value of 21.5 cd/m2, with an area under the ROC curve of 0.897. The present ex vivo study potentially provides a powerful near-infrared approach for quantitative discrimination between EAOC and benign OE, with high sensitivity and specificity, which may have clinical applications. PMID- 29456706 TI - Comparison of single- and triple-injection methods for ultrasound-guided interscalene brachial plexus blockade. AB - Ultrasound-guided interscalene brachial plexus blockade (IBPB) has a relatively high success rate in shoulder surgery; however, whether multiple injections are superior to a single injection (SI) is currently unknown. In the present study, ultrasound-guided SI and triple-injection (TI) IBPBs were compared in a prospective randomized trial. A total of 111 patients undergoing arthroscopic shoulder surgery and presenting with an American Society of Anesthesiologists physical status grading of I-II were randomly allocated to receive IBPB with 15 ml of 1% ropivacaine as a SI or TI. Performance time, procedure-related pain scores, success rate and prevalence of complications were recorded. The distribution of sensory and motor block onset in the radial, median, ulnar and axillary nerves were assessed every 5 min until 30 min post-local anesthetic injection. The duration of sensory and motor blocks were also assessed. A significantly longer performance time was recorded in the TI group (P<0.001). No significant difference was observed in success rate (91% in TI vs. 88% in SI) 30 min post-injection, and the prevalence of complications and procedure-related pain were similar between the two groups. Sensory and motor blocks of the ulnar nerve in the TI group were significantly faster and more successful compared with the SI group at all time points (P<0.041). It was also observed that sensory and motor blocks in the TI group were prolonged compared with the SI group (P<0.041). In conclusion, the TI method exhibited a faster time of onset and resulted in a more successful blockade of the ulnar nerve. TI method may be a more effective approach for IBPB in a clinical setting. PMID- 29456707 TI - Resveratrol induces autophagic apoptosis via the lysosomal cathepsin D pathway in human drug-resistant K562/ADM leukemia cells. AB - The aim of the present study was to investigate the crosstalk between resveratrol (Res)-induced autophagy and apoptosis, and the molecular pathway by which autophagy leads to apoptotic death in drug-resistant K562/ADM leukemia cells. The viability of K562/ADM cells was determined using the MTT assay. The formation of autophagic vacuoles was detected using transmission electron microscopy and monodansylcadaverine (MDC) staining. Cell apoptosis was evaluated using flow cytometry. The expression of apoptosis- or autophagy-associated proteins was measured using western blotting. The results indicated that treatment with Res inhibited cell viability in a concentration-dependent manner. Furthermore, the numbers of MDC-positive fluorescent points, autophagic vacuoles and autolysosome engulfed cytoplasmic materials were markedly increased in Res-treated K562/ADM cells compared with untreated cells, as determined using fluorescence microscopy and transmission electron microscopy. Res-induced apoptosis was associated with increased cleaved caspase-3 and B-cell lymphoma 2 associated X protein, and decreased B-cell lymphoma 2 (Bcl-2) protein expression levels when compared with the control (P<0.05). However, the proportion of apoptotic cells decreased from 69.6 to 41.0% (40 umol/l Res) and from 77.3 to 58.8% (80 umol/l Res) following pre-treatment with the autophagy inhibitor 3-methyladenine (P<0.01). The protein expression levels of microtubule-associated protein 1A/1B-light chain 3 and beclin 1, two markers of autophagy, were upregulated in Res-treated cells compared with the control (P<0.05). In addition, lysosomal cathepsin D (Cath D) release increased during Res-induced autophagy and apoptosis (P<0.05). The present results demonstrated that Res-induced apoptosis of K562/ADM cells was autophagy-dependent and the released Cath D may trigger caspase-dependent cell death through the Bcl-2 family of proteins. Furthermore, the present data indicate that to enhancement of the autophagy-cathepsin-apoptosis pathway may be an effective approach for overcoming anticancer drug resistance. PMID- 29456708 TI - Meniscal allograft transplantation using a novel all-arthroscopic technique with specifically designed instrumentation. AB - The present study describes a novel all-arthroscopic technique for medial and lateral meniscal allograft transplantation (MAT). Surgical instruments were specifically designed to assist in the all-arthroscopic approach for MAT. The bone plug attachment technique, either the arthroscopic-assisted or all arthroscopic approach, attaches bone plugs to the anterior and posterior horns. In the present study, two sets of surgical implements were designed: One to produce bone plugs of predefined sizes in the anterior and posterior horns of the allograft meniscus (bone plug implements) and a second to create bone tunnels in the receptor tibial plateau to hold the bone plugs (bone tunnel implements). The present study demonstrated that an all-arthroscopic approach to MAT was feasible. Furthermore, the specifically designed surgical instruments allowed for consistent preparation of grafts and recipient tissues, contributing to a standardized approach to MAT. The present findings indicate that an all arthroscopic approach to MAT may be achievable. They also provide the incentive for future clinical studies to directly compare the outcomes and to initiate the standardization of the procedure to optimize MAT and maximize patient outcomes and quality of life. PMID- 29456709 TI - Anterior spinal instrumentation combining a prosthetic disc nucleus with a flexible stabilization device: Manufacture and use in intervertebral disc repair. AB - Artificial disc replacement alone is unable to completely cure cervical degenerative diseases; thus, a stabilization device markedly improves patient recovery. In order to meet this requirement, an anterior spinal instrumentation combining a prosthetic disc nucleus with a flexible stabilization device (ASI combining PDN/FD) was developed. An artificial disc was designed and manufactured using polyvinyl alcohol hydrogel (PVA-H) with a repeated freeze-melting technique, and subsequently the dehydration and swelling properties of the PVA-H were investigated. A canine animal model was then used to compare the differences in the degeneration of cervical discs adjacent to the operative segment with PDN/FD against a plate fixation system, without the interferences of brace intensity, which was ensured by pressure monitoring the dog's intervertebral disc adjacent to operative segments. The in vivo results demonstrated a clear decrease in the degeneration of the adjacent disc with the use of PDN/FD as compared with the plate fixation system. In conclusion, PDN/FD may offer a promising method for the treatment of cervical degenerative disease. PMID- 29456710 TI - Mechanism of apoptosis induction associated with ERK1/2 upregulation via goniothalamin in melanoma cells. AB - The present study aimed to investigate the effect of goniothalamin on apoptosis induction in the A375 melanoma cell line. Melanoma is a type of skin cancer with increased prevalence and no potential standard treatment. Goniothalamin is a plant, bioactive styrly-lactone, which has various bioactivities including anti microbial, anti-inflammatory and anti-cancer. Apoptosis induction by goniothalamin has been studied in numerous cancer cell lines, however not in the melanoma cell line A375. The results of the MTT assay demonstrated that goniothalamin induced anti-proliferation in a dose dependent manner. Hoechst staining assay demonstrated that goniothalamin induced chromatin condensation and apoptotic bodies in A375 treated cells, and JC-1 staining revealed that goniothalamin induced mitochondrial membrane dysfunction in A375 cells. In addition, goniothalamin decreased the level of anti-apoptotic proteins myeloid cell leukemia 1, B cell lymphoma (Bcl)-2 and Bcl-extra large, whereas it increased the level of pro-apoptotic proteins, Bcl-2 Associated X, apoptosis regulator, t-BID and Bim in A375 treated cells. In addition, goniothalamin also increased active caspase-9, -7 and cleaved-poly (ADP-ribose) polymerase expression in A375 treated cells. Furthermore, phosphorylated (p)-pyruvate dehydrogenase kinase (PDK) 1 (Ser241) and p-RAC-alpha serine/threonine-protein kinase (Akt; Ser473) were decreased, however c-Jun and p-extracellular signal regulated kinase (ERK)1/2 were increased upon goniothalamin treatment. These results suggest that goniothalamin has an effect, as anti-proliferation and apoptosis induction in A375 cells were associated with upregulated p-ERK1/2, c Jun and downregulated p-PDK1 (Ser241), p-Akt (Ser473) in A375 cells. Therefore, goniothalamin may be a potential candidate for anti-cancer drug development for melanoma treatment. PMID- 29456711 TI - Value of the albumin-bilirubin score in the evaluation of hepatitis B virus related acute-on-chronic liver failure, liver cirrhosis, and hepatocellular carcinoma. AB - The aim of the present study was to investigate the value of the albumin bilirubin (ALBI) score in the assessment of the disease conditions of hepatitis B virus (HBV)-related acute-on-chronic liver failure (HBV-ACLF), HBV-related liver cirrhosis (HBV-LC) and HBV-related hepatocellular carcinoma (HBV-HCC). A total of 395 patients with HBV-ACLF, HBV-LC, or HBV-HCC were retrospectively studied. The ALBI, Child-Turcotte-Pugh (CTP), and Model for End-Stage Liver Disease (MELD) scores of the patients were calculated, and the relationships between the ALBI score and the CTP and MELD scores were investigated. Furthermore, the ALBI grading was tested for the evaluation of the severity and stages of HBV-ACLF, HBV LC, and HBV-HCC, especially when classifying the clinical stages of HBV-ACLF. The mean ALBI scores of the HBV-ACLF, HBV-LC, and HBV-HCC patients were -1.17+/-0.55, -1.76+/-0.66 and -2.59+/-0.62, respectively; the mean CTP scores were 10.70+/ 1.81, 8.19+/-1.25 and 5.81+/-1.22, respectively; and the mean MELD scores were 19.93+/-7.44, 11.10+/-4.39 and 7.01+/-3.22, respectively. The ALBI scores were positively correlated with the CTP and MELD scores. The mean ALBI score and the frequency of grade 3 disease were higher in HBV-ACLF patients than in patients with HBV-LC or HBV-HCC. A later HBV-ACLF stage resulted in a higher frequency of ALBI grades of 3. In conclusion, ALBI scores exhibited parallel tendencies to the CTP and MELD scores in HBV-ACLF, HBV-LC, and HBV-HCC patients; thus, ALBI grading may be a simple but applicable method for the evaluation of the functional status of patients with HBV-related end-stage liver diseases. PMID- 29456712 TI - MicroRNA-144 functions as a tumor suppressor in gastric cancer by targeting cyclooxygenase-2. AB - Gastric cancer (GC) poses a serious public health threat and the 5-year survival rate of patients with GC is low. MicroRNAs (miRNAs/miRs) may serve oncogenic or tumor suppressor functions during tumorigenesis by regulating cell proliferation, apoptosis, migration and invasion and it has been demonstrated that they may be dysregulated in various types of cancer. The present study demonstrated that miR 144 and GATA4 were downregulated in GC tissues and cell lines and suggested that this may be due to hypermethylation. Additionally, miR-144 and GATA4 had synergistic effects on GC cells by repressing cell proliferation and inducing cell cycle arrest and apoptosis. The results of bioinformatics and a luciferase reporter assay indicated that cyclooxygenase-2 (COX-2) is a direct target of miR 144 and that miR-144 negatively regulated the expression of COX-2, which inhibits the viability of GC cells. GATA4 also induced a similar effect on COX-2. Taken together, the results of the present study may improve understanding of the underlying mechanism of miR-144 and GATA4 in GC. PMID- 29456713 TI - In vitro study on the role of SOX9 in trastuzumab resistance of adenocarcinoma of the esophagogastric junction. AB - Trastuzumab is recommended for the treatment of human epidermal growth factor receptor 2-positive adenocarcinoma of the esophagogastric junction (AEG) in combination with chemotherapy; however, drug resistance has severely affected its clinical application. The present study aimed to investigate the effect of sex determining region Y-box 9 (SOX9), a prognostic marker in adjuvant oncological settings, on AEG cell proliferation and apoptosis in the presence or absence of trastuzumab. Furthermore, the molecular mechanism underlying the role of SOX9 in trastuzumab resistance was explored. ESO26 cells were treated with various concentrations of trastuzumab, and trastuzumab induced SOX9 expression in a concentration-dependent manner, as determined by reverse transcription quantitative polymerase chain reaction and western blotting analyses. Transfection of ESO26 cells with SOX9 small interfering RNA was conducted to knock down SOX9 expression, and the results of MTT and flow cytometry assays demonstrated that SOX9 knockdown sensitized ESO26 cells to trastuzumab by inhibiting cell proliferation and enhancing cell apoptosis. In addition, it was observed that the trastuzumab-induced phosphorylation of AKT was suppressed by SOX9 knockdown. In conclusion, the present study demonstrated that SOX9 participated in trastuzumab resistance by affecting cell proliferation and apoptosis, and indicated that SOX9 may exert its effect on trastuzumab resistance via activation of the phosphatidylinositol-3-kinase/AKT signaling pathway. This study identified a novel mechanism underlying trastuzumab resistance in vitro and may be useful in improving the efficacy of trastuzumab treatment. PMID- 29456714 TI - FOXK1 promotes glioblastoma proliferation and metastasis through activation of Snail transcription. AB - Forkhead box K1 (FOXK1) has been identified to have a crucial function in development and oncogenesis. However, its role in glioblastoma has remained largely elusive and was therefore assessed in the present study. In human glioblastoma multiforme (GBM) tissue samples, FOXK1 was determined to be highly expressed compared with adjacent normal tissue samples. In addition, high levels of FOXK1 were detected in the T98G and LN18 GBM cell lines as compare with those in normal human astrocytes. Of note, high expression of FOXK1 was revealed to be associated with metastasis and tumor size. Loss- and gain-of-function experiments were then performed to determine whether FOXK1 regulates epithelial to mesenchymal transition (EMT) and cell proliferation. Knockdown of FOXK1 significantly suppressed EMT and metastasis of GBM cells, while ectopic expression of FOXK1 promoted them. A luciferase reporter assay and a chromatin immunoprecipitation assay revealed that FOXK1 activated the transcription of Snail. In addition, as the results indicated that FOXK1 promotes GBM cell proliferation, the potential effect of FOXK1 on the cell cycle and apoptosis were further assessed. While FOXK1 had no effect on apoptosis, it promoted cell proliferation via enhancing the S-phase population. In brief, the present study indicated that FOXK1 acts as an oncogene with a key function in glioblastoma cell proliferation and EMT. PMID- 29456715 TI - Protective effect of vitexin reduces sevoflurane-induced neuronal apoptosis through HIF-1alpha, VEGF and p38 MAPK signaling pathway in vitro and in newborn rats. AB - Previous studies have demonstrated that Vitexin possesses antihypertensive, anti inflammatory and potential anticancer effects. The present study aimed to investigate whether the protective effect of vitexin protects against sevoflurane induced neuronal apoptosis and the underlying mechanisms of this protective effect. The results demonstrated that Vitexin pretreatment significantly reduced neuronal apoptosis, and inhibited caspase-3 activity, apoptosis regulator BAX protein expression and malondialdehyde levels in sevoflurane-induced newborn rats. In addition, Vitexin pretreatment increased superoxide dismutase and glutathione peroxidase activity. Furthermore, it was revealed that treatment with vitexin induced hypoxia inducible factor 1alpha subunit (HIF-1alpha) and vascular endothelial growth factor (VEGF) protein expression, and suppressed phosphorylated-p38 MAP kinase (p38) protein expression in sevoflurane-induced newborn rat. Together, the results of the current study suggest that the protective effect of vitexin reduces sevoflurane-induced neuronal apoptosis through HIF-1alpha-, VEGF- and p38-associated signaling pathways in newborn rats. PMID- 29456716 TI - Transient severe motion during arterial phase in patients with Gadoxetic acid administration: Can a five hepatic arterial subphases technique mitigate the artifact? AB - Gadoxetic acid (Gd-EOB-DTPA) is a hepatocyte-specific magnetic resonance (MR) contrast agent, which has been increasingly used in recent years. However, it has been reported that Gd-EOB-DTPA related transient severe motion (TSM) is sometimes observed during the hepatic arterial phase of MR imaging, which may influence image quality. Since the hepatic arterial phase of contrast enhancement is used for the diagnosis of hepatocellular carcinoma, it is crucial to obtain a decent arterial phase imaging. The present study analyzed motion in patients receiving Gd-EOB-DTPA, comparing a single arterial phase acquisition to a five arterial phase acquisition to determine whether the multiphase acquisition was able to alleviate the TSM-related hepatic arterial MR imaging artifact. It was demonstrated that the single-phase acquisition failed to provide adequate diagnostic image quality in patients with TSM, whereas the multiphase arterial acquisition provided acceptable image quality in 20/22 (90.9%) patients with TSM. In conclusion, the results of the present study demonstrated that multiphase arterial acquisition is superior to single-phase arterial acquisition, mitigating arterial MR imaging artifacts caused by TSM after the administration of Gd-EOB DTPA. PMID- 29456717 TI - Naringin ameliorates endothelial dysfunction in fructose-fed rats. AB - High fructose consumption is associated with metabolic disorders including hyperglycemia and dyslipidemia, in addition to endothelial dysfunction. Naringin, a flavonoid present in citrus fruit, has been reported to exhibit lipid lowering, antioxidant, and cardiovascular protective properties. Therefore, the present study investigated the effect of naringin on fructose-induced endothelial dysfunction in rats and its underlying mechanisms. Male Sprague-Dawley rats were given 10% fructose in drinking water for 12 weeks, whereas control rats were fed drinking water alone. Naringin (100 mg/kg) was orally administered to fructose fed rats during the last 4 weeks of the study. Following 12 weeks, blood samples were collected for measurement of blood glucose, serum lipid profile and total nitrate/nitrite (NOx). Vascular function was assessed by isometric tension recording. Aortic expression of endothelial nitric oxide synthase (eNOS), phosphorylated eNOS (p-eNOS), and nitrotyrosine were evaluated by western blot analysis. Fructose feeding induced increased levels of blood glucose, total cholesterol, triglyceride, and low density lipoprotein. In rat aortae, fructose reduced acethycholine-induced vasorelaxation, without affecting sodium nitroprusside-induced vasorelaxation. Treatment of fructose-fed rats with naringin restored fructose-induced metabolic alterations and endothelial dysfunction. Fructose-fed rats also exhibited decreased serum NOx level, reduced eNOS and p-eNOS protein expression, and enhanced nitrotyrosine expression in aortae. These alterations were improved by naringin treatment. The results of the present study suggested that naringin treatment preserves endothelium-dependent relaxation in aortae from fructose fed rats. This effect is primarily mediated through an enhanced NO bioavailability via increased eNOS activity and decreased NO inactivated to peroxynitrite in aortae. PMID- 29456719 TI - Estrogen receptor-alpha promoter methylation is a biomarker for outcome prediction of cisplatin resistance in triple-negative breast cancer. AB - A number of previous studies have indicated the presence of a link between estrogen receptor-alpha (ERalpha) methylation and triple-negative breast cancer (TNBC). However, the association between ERalpha methylation and drug resistance during the treatment of TNBC remains unclear. Methylation-specific polymerase chain reaction was used to investigate the methylation of ERalpha in the genomic DNA of 35 patients with TNBC who were defined as cisplatin-based chemotherapy resistant using chemosensitivity testing. Survival probabilities by covariates were assessed using Kaplan-Meier estimator survival analysis and Cox's proportional hazards models, adjusting for age, menopausal status, tumor size, lymph node metastasis and ERalpha promoter DNA methylation. Of the 35 patients with TNBC analyzed, 8 exhibited ERalpha promoter DNA methylation. Cisplatin resistance was confirmed to be overwhelmingly associated with ERalpha methylation by univariate and multivariate analysis. Even in a limited analysis in patients with ERalpha methylation, the results generated from methylated tumor tissue and unmethylated tumor tissue revealed that expression of breast cancer type 1/2 susceptibility proteins was increased in ERalpha-methylated breast tumor tissue compared with in unmethylated tissue. The ERalpha methylation group tended to have significantly shorter progression-free (P=0.010) and overall (P=0.023) survival times compared with those in the unmethylated group. Similarly, shorter progression-free (P=0.024) and overall (P=0.018) survival times were observed in the cisplatin-resistant group compared with the cisplatin-non-resistant group. ERalpha methylation predicts a poor clinical outcome for patients with TNBC. The results of the present study indicated that ERalpha methylation may be a candidate surrogate biomarker for outcome prediction and cisplatin resistance in TNBC. Further investigation is required to identify potential biomarkers in a larger cohort in a prospective study. PMID- 29456718 TI - Molecular challenges of neuroendocrine tumors. AB - Neuroendocrine tumors (NETs) are a very heterogeneous group that are thought to originate from the cells of the endocrine and nervous systems. These tumors develop in a number of organs, predominantly in the gastrointestinal and pulmonary systems. Clinical detection and diagnosis are reliable at the late stages when metastatic spread has occurred. However, traditional conventional therapies such as radiation and chemotherapy are not effective. In the majority of cases even surgical resection at that stage is unlikely to produce promising reusults. NETs present a serious clinical challenge, as the survival rates remain low, and as these rare tumors are very difficult to study, novel approaches and therapies are required. This review will highlight the important points of accumulated knowledge covering the molecular aspects of the role of neuroendocrine cells, hormonal peptides, the reasons for ectopic hormone production in NET, neuropeptides and epigenetic regulation as well as the other challenging questions that require further understanding. PMID- 29456720 TI - miR-494 inhibits cervical cancer cell proliferation through upregulation of SOCS6 expression. AB - It is unclear how microRNA (miR)-494 inhibits the proliferation of cervical cancer cells by altering the expression of SOCS6. Therefore, the present study aimed to investigate the molecular mechanism underlying miR-494 regulation of suppressor of cytokine signaling 6 (SOCS6) in human cervical cancer samples and the human cervical cancer HeLa cell line. The expression of miR-494 was determined using reverse transcription-quantitative polymerase chain reaction. In addition, TargetScan was used to predict miR-494 target genes and the luciferase reporter assay was used to determine whether SOCS6 was a direct target of miR 494. The results of the present study demonstrated that compared with the cervical intraepithelial neoplasia and normal cervical tissues, the miR-494 expression level in cervical cancer samples was significantly decreased (P<0.01). In addition, compared with normal cervical tissue, miR-494 expression level was significantly decreased in cervical intraepithelial lesions (P<0.05). Furthermore, the expression of miR-494 was associated with patients with or without lymph node metastasis, clinical stage and depth of stromal invasion (P<0.01); however, miR-494 expression was not identified to be associated with age, tumor size and menopausal status (P>0.05). Transfection of a miR-494 mimic significantly increased the expression level of miR-494 in HeLa cells (P<0.01), and anti-miR-494 transfection decreased the expression of miR-494 (P<0.01). An MTT proliferation assay and Boyden chamber invasion ability assay revealed that miR-494 mimic transfection significantly inhibited the proliferation, and invasion ability of HeLa cells (P<0.01), whereas anti-miR-494 transfection significantly increased the proliferation and invasion ability (P<0.05). SOCS6 was predicted, using bioinformatics, to be the target gene of miR-494 and this was validated using a luciferase reporter assay. Western blot analysis revealed that transfection of miR-494 significantly increased the expression of SOCS6 in HeLa cells, and transfection of anti-miR-494 significantly decreased the expression of SOCS6. Therefore, the results of the present study demonstrated that miR-494 expression in cervical cancer was significantly decreased. Exhibiting a decreased expression level of miR-494 may result in enhanced proliferative and invasive abilities of HeLa cell, thus contributing to the occurrence, and development of cervical cancer. PMID- 29456721 TI - Combined treatment with D-allose, docetaxel and radiation inhibits the tumor growth in an in vivo model of head and neck cancer. AB - The present study was designed to evaluate the effect of one rare sugar, D allose, on normal human cells and cutaneous tissue, and to investigate the radiosensitizing and chemosensitizing potential of D-allose in an in vivo model of head and neck cancer. Results indicated that D-allose did not inhibit the growth of normal human fibroblasts TIG-1 cells, and no apoptotic changes were observed after D-allose and D-glucose treatment. The mRNA expression levels of thioredoxin interacting protein (TXNIP) in TIG-1 cells after D-allose treatment increased by 2-fold (50.4 to 106.5). Conversely, the mRNA expression levels of TXNIP in HSC3 cancer cells increased by 74-fold (1.5 to 110.6), and the thioredoxin (TRX)/TXNIP ratio was markedly reduced from 61.7 to 1.4 following D allose treatment. Combined multiple treatments with docetaxel, radiation and D allose resulted in the greatest antitumor response in the in vivo model. Hyperkeratosis, epidermal thickening and tumor necrosis factor-alpha immunostaining were observed following irradiation treatment, but these pathophysiological reactions were reduced following D-allose administration. Thus, the present findings suggest that D-allose may enhance the antitumor effects of chemoradiotherapy whilst sparing normal tissues. PMID- 29456722 TI - Fucosterol exhibits selective antitumor anticancer activity against HeLa human cervical cell line by inducing mitochondrial mediated apoptosis, cell cycle migration inhibition and downregulation of m-TOR/PI3K/Akt signalling pathway. AB - Cervical cancer greatly contributes to cancer-associated mortalities worldwide. The growing incidence of cervical cancer is of primary concern, and has signaled the need for multiple treatment options. Despite preliminary responses to chemotherapy and/or surgical interventions, the tumors consistently relapse. Previously, natural products gained attention for their diverse bioactivities, which include however are not limited to, neuroprotective, antimicrobial and anticancer effects. The present study evaluated the anticancer activity of fucosterol against a panel of human cancer cell lines. Results indicated that fucosterol exhibited selective inhibitory activity against human HeLa cervical cancer cell line with an IC50 of 40 uM. Fucosterol also induced apoptosis in HeLa cells and prompted reactive oxygen species mediated alterations in mitochondrial membrane potential. It triggered cell cycle arrest of HeLa cells at G2/M check point and exerted inhibitory effects on cell migration. The activation of the phosphoinositide-3-kinase (PI3K)/AKT Serine/Threonine Kinase 1 (AKT)/mechanistic target of Rapamycin (mTOR) pathway is important in cancer tumorigenesis, progression and chemotherapy resistance. The results demonstrated that fucosterol significantly inhibited the expression levels of key proteins of the PI3K/Akt/mTOR signaling pathway. Overall, the results of the present study suggest that fucosterol may prove beneficial in the management of cervical cancer. PMID- 29456724 TI - Long noncoding RNA BLACAT1 promotes cell proliferation and invasion in human cervical cancer. AB - Cervical cancer is one of the leading causes of mortality in females worldwide. Predisposition to distant metastasis has reduced the prognosis of this malignancy, thus the identification of a novel agent for metastatic cervical cancer is required. Long noncoding RNAs (LncRNAs) have been reported to serve significant roles in human tumorigenesis. The present study aimed to investigate the effects of a newly discovered LncRNA bladder cancer associated transcript 1 (non-protein coding) (BLACAT1) on cell proliferation and metastasis in cervical cancer. A total of 100 patients with cervical cancer were included, and tumor tissues as well as the adjacent non-cancerous counterparts were collected for reverse transcription-quantitative polymerase chain reaction analysis. It was demonstrated that BLACAT1 was highly expressed in human cervical cancer tissues and cell lines. The knockdown of BLACAT1 with specific short hairpin RNA reduced colony formation rates in ME180 and C33A cells. Cell cycle and cell proliferation assays revealed that depletion of BLACAT1 in ME180, and C33A cells arrested the cell cycle at the G0/G1 phase and inhibited cell proliferation. Transwell assays demonstrated that the knockdown of BLACAT1 inhibited cell migration and invasion in ME180, and C33A cells. Moreover, wound-healing assays supported the aformentioned observations. Western blot analysis showed that the knockdown of BLACAT1 in ME180 and C33A cells decreased the protein levels of cyclin B1, cell division cycle 25C, and N-cadherin, while increasing the protein level of E cadherin. These findings indicated the oncogenic potential of BLACAT1 in cervical cancer, which may provide novel insights for the clinical diagnosis and treatment of cervical cancer. PMID- 29456723 TI - miR-96 promotes breast cancer metastasis by suppressing MTSS1. AB - Novel, non-invasive biomarkers with high sensitivity and specificity are critical for breast cancer treatment, and prognosis. MicroRNA (miR)-96 has been demonstrated to be highly expressed in several solid malignancies, including breast cancer. However, its expression and function in the metastasis and prognosis of breast cancer have not been fully explored, and its regulation mechanisms remain unclear. In the present study, the serum miR-96 expression in healthy controls, benign and malignant breast cancer types was compared by using reverse transcription-quantitative polymerase chain reaction. The effect of chemotherapy on miR-96 expression in breast cancer was also investigated. Result revealed that miR-96 expression was increased in malignant breast cancer types and reduced in patients following chemotherapy treatment. The effect of miR-96 manipulation on the migration of breast cancer cells was also investigated by using wound healing, and Transwell migration assays. These results revealed that the induced expression of miR96 led to enhanced wound closing and trans-membrane cell numbers. By using bioinformatics analysis, western blotting and immunohistochemical staining, the metastasis suppressor-1 (MTSS1) gene was identified to be the functional target of miR-96 in the promotion of cell migration. In conclusion, it was identified that miR-96 exhibited an increased level in serum samples of patients with malignant breast cancer in comparison with benign breast tumor types and health controls and may be substantially reduced by chemotherapy treatment, implying that it may be used as a prognostic marker in breast cancer. miR-96 overexpression may inhibit migration of breast cancer cells by downregulating MTSS1 expression. PMID- 29456725 TI - Application of deep learning to the classification of images from colposcopy. AB - The objective of the present study was to investigate whether deep learning could be applied successfully to the classification of images from colposcopy. For this purpose, a total of 158 patients who underwent conization were enrolled, and medical records and data from the gynecological oncology database were retrospectively reviewed. Deep learning was performed with the Keras neural network and TensorFlow libraries. Using preoperative images from colposcopy as the input data and deep learning technology, the patients were classified into three groups [severe dysplasia, carcinoma in situ (CIS) and invasive cancer (IC)]. A total of 485 images were obtained for the analysis, of which 142 images were of severe dysplasia (2.9 images/patient), 257 were of CIS (3.3 images/patient), and 86 were of IC (4.1 images/patient). Of these, 233 images were captured with a green filter, and the remaining 252 were captured without a green filter. Following the application of L2 regularization, L1 regularization, dropout and data augmentation, the accuracy of the validation dataset was ~50%. Although the present study is preliminary, the results indicated that deep learning may be applied to classify colposcopy images. PMID- 29456726 TI - Association of histone deacetylase expression with histology and prognosis of ovarian cancer. AB - Histone deacetylase (HDAC) inhibitor is known to have a cytotoxic effect on ovarian cancer cell lines. The present study analyzed the association between immunohistochemical HDAC expression and clinicopathological findings, in particular, the association with histological type and effect of chemotherapy. The histology of the 201 ovarian cancers addressed was as follows: Serous carcinoma (SEC), 100 cases; clear cell carcinoma (CCC), 56 cases; endometrioid carcinoma (EMC), 36 cases; and mucinous carcinoma (MUC), 9 cases. Immunohistochemical analyses of HDACs 1, 2, 3, 4, 5, 6 and 7 expression levels were performed using tissue microarrays, composed of 201 primary tumors and 38 tumors following chemotherapy. Overexpression of HDAC1 was detected in the nucleus of all cases with MUC, followed by CCC (80%), SEC (73%), and EMC (53%). CCC specifically demonstrated HDAC7 expression in both the nucleus (27%) and the cytoplasm (54%), and HDAC6 expression in the nucleus (34%). The comparison between prior to and following chemotherapy revealed a nuclear expression increase in HDAC1 (76% vs. 92%; P=0.03) and HDAC7 (0.0 vs. 16%; P=0.01), and cytoplasmic expression increase in HDAC6 (40 vs. 74%; P=<0.01) and HDAC7 (16 vs. 66%; P=<0.01). HDAC1 nuclear expression adversely affected overall survival in SEC (P=0.02) and EMC (P=0.03), and HDAC7 cytoplasmic expression in CCC was associated with a poor prognosis (P=0.06). In multivariate analysis, HDAC6 nuclear expression was determined as a poor prognostic factor (hazard ratio=3.51; 95% confidence interval, 1.49 to 8.27, P=<0.01). In the subgroup analysis, HDAC6 nuclear expression was associated with a poor prognosis in CCC (P=0.07), International Federation of Obstetrics and Gynecology stage III/IV (P=0.07), and suboptimal surgery (P=<0.01). In conclusion, HDACs may be associated with the prognosis of ovarian cancers, depending on the histological subtypes, and upregulated following chemotherapy. HDAC1, 6 and 7 may therefor act as promising therapeutic targets in the future. PMID- 29456727 TI - Risk factors and coping strategies of severe community-acquired pneumonia in chemotherapy induction period of acute leukemia. AB - The risk factors and coping strategies of severe community-acquired pneumonia (SCAP) in chemotherapy induction period of acute leukemia were investigated. Eighty-six patients with CAP in chemotherapy induction period of acute leukemia in Dezhou Hospital from March 2014 to February 2017 were selected and divided into observation group (SCAP group, n=45) and control group (non-SCAP group, n=41) according to the acute physiology and chronic health evolution II (APACHE II) score. The blood, sputum, nasopharyngeal secretion and pleural effusion samples were collected from patients in both groups, and the samples were detected for pathogens, followed by the analysis of relevant factors. The dynamic changes in the sequential organ failure assessment (SOFA) score, procalcitonin (PCT), D-dimer (D-D) and C-reactive protein (CRP) levels in patients were observed before and after the corresponding treatment strategies were taken. The total distribution ratio of pathogens from high to low in the two groups was as follows: bacterium, virus, fungus, mycoplasma and chlamydia trachomatis; there was no significant difference between the two groups (P>0.05). Logistic regression analysis showed that the repeated infection (OR=3.315, P=0.005), multi resistant bacterial infection (OR=1.915, P=0.008) and D-D (OR=1.936, P=0.009) were independent risk factors for SCAP (P<0.05). After different coping strategies were taken, the SOFA score, PCT, D-D and CRP levels in the two groups were significantly decreased, and they were obviously higher in observation group than those in control group (P<0.05). Repeated infection, D-D level and multi resistant bacterial infection are the risk factors affecting the SCAP in chemotherapy induction period of acute leukemia. The coping strategies can effectively relieve the patient's condition, reduce the severity of disease and improve the survival rate of patients. PMID- 29456728 TI - Values of miR-34a and miR-218 expression in the diagnosis of cervical cancer and the prediction of prognosis. AB - The expression levels of microribonucleic acid 34a (miR-34a) and miR-218 in the serum and tumor tissues of patients with cervical cancer were investigated to explore their relationship with the diagnosis of cervical cancer. Fifty patients with cervical cancer were selected, and 30 normal patients were selected as the control group. The expression levels of miR-34a and miR-218 were detected by quantitative real-time polymerase chain reaction. The relationship between the expression of miR-34a and miR-218 was analyzed using Pearson's correlation coefficient, and the receiver operating characteristic (ROC) curve was plotted for the analysis of values of the expression of miR-34a and miR-218. The correlation of the expressions of miR-34a and miR-218 in the serum with pathological parameters and the prognosis was analyzed. The expression levels of miR-34a and miR-218 in cervical cancer patients were significantly lower than those in normal patients. The ROC curve showed the area under curve (AUC) of miR 34a was 0.893, and miR-218 was 0.794. The low expression of miR-34a in patients with cervical cancer was correlated with the degree of tumor differentiation, lymph node metastasis and the International Federation of Gynecology and Obstetrics staging. The low expression of miR-218 was related to the degree of differentiation as well as invasion and metastasis. The 5-year overall survival rate of patients was 66%, and the low expression of miR-34a and miR-218 indicated a worse survival prognosis. The low expression of miR-34a in patients with cervical cancer is related to the degree of tumor differentiation as well as invasion and metastasis, and the low expression of miR-218 is related to the degree of tumor differentiation, invasion and metastasis and clinical staging. miR-34a and miR-218 in the serum can be used as markers for the diagnosis of cervical cancer and reference indicators for the evaluation of prognosis. PMID- 29456729 TI - Expression of matrix metalloproteinase-7 correlates with the invasion of T1 colorectal carcinoma. AB - T1 colorectal carcinomas (CRCs) are an initial site of metastatic spread. Various risk factors for lymph node metastasis have been investigated in T1 CRCs. However, the major step in the entire process of metastasis remains unclear. In terms of carcinoma invasion and metastasis, matrix metalloproteinases (MMPs) have recently gained increasing attention. Notably, MMP-7 is frequently overexpressed in CRCs, but its implication has not been determined in T1 CRCs yet. The present study aimed to clarify the associations between the pathological risk factors of T1 CRCs and MMP-7. In the current study, 211 lesions of T1 CRC that were resected endoscopically or surgically at Showa University Northern Yokohama Hospital (Yokohama, Japan) between April 2008 and December 2009 were retrospectively analyzed. MMP-7 was immunostained and evaluated by its frequency of expression. Pathological factors of T1 CRCs were analyzed in association with MMP-7 expression. Furthermore, the ultrastructural alterations of carcinoma invasion were examined using low vacuum-scanning electron microscopy (LV-SEM). MMP-7 expression was associated with venous invasion (P=0.005), and LV-SEM revealed the disappearance of the normal structure of collagen and elastic fibers of veins invaded by tumor cells expressing MMP-7. At the invasive front, MMP-7 has a vital role in carcinoma invasion, correlating with venous invasion of T1 CRCs. PMID- 29456730 TI - The regulation and function of microRNA-377/RASSF8 signaling axis in gastric cancer. AB - Gastric cancer is a major cause of cancer-associated mortality worldwide. The aberrant expression of microRNA (miRNA) is involved in tumorigenesis. Ras proteins transfer information from the extracellular environment to internal cellular compartments and are essential in numerous signal transduction pathways. To investigate the regulation, function and clinical significance of the miRNA377/Ras association domain family (RASSF) 8 signaling axis in gastric cancer, reverse transcription-quantitative polymerase chain reaction, immunohistochemistry, cell counting kit-8, western blotting, and Transwell assays were used. The results revealed that expression of RASSF8 was significantly upregulated in normal gastric tissues compared with gastric cancer, which was further confirmed by immunohistochemical analysis, and its expression level was increased in normal gastric cells compared with gastric cancer cell lines. However, the expression of miR-377 was significantly upregulated in gastric cancer compared with normal gastric tissues. In addition, RASSF8 overexpression in BGC-823 gastric cancer cells significantly inhibited the proliferation, apoptosis and invasive abilities of cells. Whereas miR-377 attenuated these effects due to downregulated RASSF8 expression by directly targeting its 3' untranslated region. Furthermore, in the current study, miR-377 was not able to reverse the effects of RASSF8 overexpression on gastric cancer cells. Collectively, the RASSF8 gene may represent a novel molecular target involved in gastric cancer development and may be useful in targeted therapy of patients with gastric cancer. PMID- 29456731 TI - Analysis of middle- and long-term efficacy of thoracoscope-assisted segmental resection of the lung on non-small cell lung cancer in the early stage. AB - We investigated the short- and long-term efficacy of thoracoscope-assisted segmental resection of lung of non-small cell lung cancer (NSCLC). We selected a total of 94 patients with lung cancer in the early stage who were admitted to The First People's Hospital of Xuzhou for treatment between March 2011 and February 2012. Patients were divided randomly into either the control group (n=47) or the observation group (n=47). In the observation group, patients received thoracoscope-assisted segmental resection of lung, while in the control group, the conventional thoracic surgery was performed for treatment. After surgeries, we observed the incidence rate of complications among the two groups, and enzyme linked immunosorbent assay (ELISA) was adopted to detect levels of inflammatory factors. We also compared the cardiac and pulmonary functions, the levels of immunoglobulins and subgroups of T lymphocytes in the peripheral blood of the patients. In addition, all patients attended a 5-year follow-up to determine the recurrence and survival rate. Compared to the control group, patients in the observation group had significantly less intra-operative bleeding volume, a shorter duration of surgery, and suffered slighter pain after surgery (P<0.05). After surgery, the incidence rate of complications in the observation group was significantly lower than that in the control group (P<0.05). After surgeries, patients in both groups experienced a remarkable improvement in cardiac and pulmonary functions, and the improvement in the observation group was superior to that of the control group (P<0.05). During the 5-year follow-up, the survival rate of the observation group is significantly higher than that in thecontrol group, and patients in the observation group experienced a lower recurrence rate than those in the control group (P<0.05). Thus, thoracoscope-assisted segmental resection of lung is of great significance in clinical practice. PMID- 29456732 TI - Two protein-coding genes act as a novel clinical signature to predict prognosis in patients with ovarian serous cystadenocarcinoma. AB - Ovarian cancer is the seventh most common type of cancer and the eighth most common cause of cancer-associated mortality among women. A number of studies have hypothesized that the expression status of certain genes may be used to predict prognosis in ovarian cancer. In the present study, the RNA expression data from next-generation sequencing and the clinical information of 413 patients from The Cancer Genome Atlas dataset was downloaded to identify the association between gene-expression level and the survival time of the patients with ovarian serous cystadenocarcinoma. A five-gene model was predicted to be significantly associated with patient survival in ovarian serous cystadenocarcinoma by using random survival forests variable hunting algorithm and Cox analysis. A total of two genes, mesencephalic astrocyte-derived neurotrophic factor and dedicator of cytokinesis 11, of the predicted five genes demonstrated positive expression in the ovarian serous cystadenocarcinoma cancer tissues by polymerase chain reaction analysis. Kaplan-Meier and Receiver Operating Characteristic analysis confirmed that the model of the two genes exhibited high sensitivity and specificity to predict the prognostic survival of patients. In conclusion, the expression of the two genes in the two-gene model was associated with the prognostic outcomes of patients with ovarian serous cystadenocarcinoma; the model demonstrated potential as a novel prognostic indicator, which may have important clinical significance. PMID- 29456733 TI - Fbxw7 regulates renal cell carcinoma migration and invasion via suppression of the epithelial-mesenchymal transition. AB - F-box and WD repeat domain containing 7 (Fbxw7) is an F-box protein that belongs to the SKP1-CUL1-F-box protein E3 ligase complex and is responsible for transferring the ubiquitin molecule to the substrate, which results in its recognition and subsequent degradation by proteasomes. Furthermore, it can identify a network of signaling proteins that function in cell growth, diversion and apoptosis. In the present study, Fbxw7 was downregulated in renal cell carcinoma (RCC) tissues compared with the adjacent non-tumor tissues and its expression was significantly associated with the tumor-node-metastasis stage, lymph node metastasis and distant metastasis in patients with RCC. Furthermore, multivariate Cox regression analyses indicated that Fbxw7 expression was an independent factor for the prediction of the overall survival of patients with RCC. A functional study demonstrated that downregulation of Fbxw7 facilitated tumor cell migration and invasion via the epithelial-mesenchymal transition (EMT). Therefore, the results of the current study indicted that Fbxw7 is an anti oncogene that serves a notable function in RCC development by suppressing RCC metastasis and the EMT, indicating the potential therapeutic value of Fbxw7 in inhibiting metastasis in RCC. PMID- 29456734 TI - Homeobox B3 promotes tumor cell proliferation and invasion in glioblastoma. AB - Glioblastoma (GBM) is the most aggressive brain tumor in adults with the highest mortality rate. Despite advances achieved in treatment and research, the median survival for patients with GBM remains <1.5 years. This figure prompted the present study to identify novel genes associated with GBM development and progression to ultimately improve GBM treatment. The current study sought to determine the role of homeobox B3 (HOXB3) in GBM cell invasion and proliferation. HOXB3 was highly expressed in GBM tissues and glioma cell lines. To establish in vitro cell models for investigation, U87-MG and U251-MG, two typical GBM cells, were selected to generate corresponding cells lines that constitutively silenced HOXB3 expression using a lentivirus-mediated RNA interference approach. The results of the knockdown revealed that glioma cells stably expressing HOXB3 short hairpin RNA exhibited significantly decreased proliferation levels when compared with untransfected cells. The effect of HOXB3 on glioma cell invasion was also examined. Silencing of HOXB3 resulted in a marked reduction in invasiveness. Furthermore, HOXB3 silencing led to the upregulation of E-cadherin and downregulation of mesenchymal markers, N-cadherin and vimentin. Taken together, the findings of the present study indicate that HOXB3 promotes cell proliferation and invasion. PMID- 29456735 TI - Metadherin contributes to epithelial-mesenchymal transition and paclitaxel resistance induced by acidic extracellular pH in nasopharyngeal carcinoma. AB - Paclitaxel resistance is a challenge to the treatment of nasopharyngeal carcinoma (NPC). An acidic extracellular pH (pHe), a hallmark of solid tumors, is demonstrated to decrease the efficacy of chemotherapy. However, the precise function of acidic pHe in mediating chemotherapy in NPC remains unknown. In the present study, acidic pHe significantly decreased the cytotoxicity of paclitaxel in NPC cells. In addition, epithelial-mesenchymal transition (EMT)-like changes were observed in NPC cells cultured at acidic pHe. Metadherin (MTDH), a novel oncogene, is expressed in multiple types of solid tumor, and is associated with several malignant cell characteristics, including malignant cell transformation, proliferation, angiogenesis, chemoresistance, invasion and metastasis. In the present study, MTDH expression was increased in NPC cells that had been cultured at an acidic pHe. Furthermore, the silencing of MTDH expression reversed EMT molecular marker expression and sensitized NPC cells to paclitaxel. Taken together, the results of the present study provide evidence to support an association between acidic pHe-induced paclitaxel resistance and MTDH-mediated EMT in NPC cells. Thus, targeting MTDH may provide a novel strategy for overcoming chemoresistance in NPC therapy. PMID- 29456736 TI - Brucea javanica seed oil enhances the radiosensitivity of esophageal cancer by inhibiting hypoxia-inducible factor 1alpha, in vitro and in vivo. AB - Brucea javanica oil emulsion (BJOE) has been used clinically to treat esophageal cancer combined with radiotherapy for numerous years in China. However, the detailed mechanism remains unclear. Thus, the effects of BJOE on the radiosensitivity of esophageal squamous cell carcinoma (ESCC) were evaluated in vitro and in vivo. The growth inhibitory effects of different BJOE concentrations were determined through an MTT assay. Radiosensitivity was evaluated through focal formation measurements and clone formation assays. The effects of BJOE on radiation-induced apoptosis were examined through flow cytometric analysis. The effects of BJOE on hypoxia-inducible factor 1alpha (HIF-1alpha) protein levels in vitro and in vivo were respectively analyzed through western blot analyses and enzyme-linked immunosorbent assays. BJOE significantly inhibited ECA109 cell proliferation in a dose- and time-dependent manner. Pretreatment with 2.5 mg/ml BJOE increased ECA109 radiosensitivity. BJOE in combination with radiation increased the DNA double-strand breaks. Compared with radiation alone, BJOE and radiation significantly increased the apoptotic rate of ECA109 cells. BJOE also decreased the HIF-1alpha protein levels in vitro and in vivo. The results from the present study demonstrated that BJOE enhanced the radiosensitivity of human ESCC. This finding was associated with the inhibition of HIF-1alpha expression. Therefore, BJOE may be a potential radiotherapy sensitization drug due to its significant anti-hypoxic activity. PMID- 29456737 TI - Distinctive profiles of tumor-infiltrating immune cells and association with intensity of infiltration in colorectal cancer. AB - Tumor-infiltrating immune cells are heterogeneous and consist of characteristic compartments, including T helper (Th)1 and regulatory T (Treg) cells that exhibit distinctive biological functions. The present study investigated the profile of infiltrating immune cells from surgically removed tumor tissues from patients with colorectal cancer. The characteristic transcription factors of Th1 and Th2 cells, Treg cells, Th17 cells and T follicular helper (Tfh) cells were analyzed. The results demonstrated that a marked increased number of Treg cells presented in tumor infiltrates when compared with non-tumor adjacent tissues. An increased number of Th1 and Tfh cells existed in tumor infiltrates compared with non tumorous adjacent tissues, while the infiltration of Th17 and Th2 cells was similar between tumor and non-tumor adjacent tissues. Furthermore, there were an increased number of Treg cells in tumors with low infiltration compared with those with high infiltration. The expression of CXC motif chemokine (CXC) receptor 3, CXC ligand (CXCL)L9 and CXCL10 was significantly increased on infiltrating T cells in tumors with high infiltration as compared with those with low infiltration. Macrophages exhibited a dominant M2 phenotype in tumor infiltrates of colorectal cancer, whereas a balanced M1 and M2 phenotype presented in macrophages from the peripheral blood. In vitro stimulation of macrophages isolated from tumor tissue of colorectal cancer with granulocyte macrophage colony-stimulating factor and lipopolysaccharide did not drive to an inflammatory phenotype. The results provide insights into the pattern of immune cell infiltration in Chinese patients with colorectal cancer. It may be beneficial that patients with colorectal cancer are screened for the defined profile along with the expression of CXCL9 and CXCL10 in order to achieve better efficacy in clinical applications of immune-based therapy, including anti programmed cell death protein 1 therapy. PMID- 29456738 TI - Recurrence of adenoid cystic carcinoma of the trachea treated with radical radiotherapy: A case report. AB - Adenoid cystic carcinoma (ACC) of the trachea is a relatively rare tumor among thoracic diseases. The present study reports the case of a 23-year-old woman with ACC of the trachea who underwent surgical resection of the tumor in The National Institute of Tuberculosis and Lung Diseases (Warsaw, Poland). Histopathological examination revealed that the tumor was not completely resected (R2 resection) and strict observation of the patient was therefore prescribed. After ~9 years of follow-up, clinical and histopathological tumor progression was confirmed and the patient was referred to the Centre of Oncology in Warsaw. The localization and advanced nature of the disease precluded surgical intervention, and radical radiotherapy was therefore performed using intensity-modulated radiation therapy. A total dose of 7,590 Gy, the planning target volume, was administered. A hyperfractionation scheme of radiotherapy was used: 2 fractions of 1.15 Gy daily, with at least a 6 h break in between. Tumor regression was observed following treatment and has been maintained for >3 years, assessed by clinical and computed tomography and positron emission tomography imaging examinations. PMID- 29456739 TI - Effects of PHA-665752 and vemurafenib combination treatment on in vitro and murine xenograft growth of human colorectal cancer cells with BRAFV600E mutations. AB - It remains unknown whether blockade of B-Raf proto-oncogene, serine/threonine kinase (BRAF)V600E signaling and MET proto-oncogene, receptor tyrosine kinase (c Met) signaling is effective in suppressing the growth of human colorectal cancer (CRC) cells. The present study investigated the effects of the vemurafenib alone and in combination with c-Met inhibitor PHA-665752 on the growth of human CRC cells in vitro and in mouse xenografts. HT-29 and RKO CRC cell lines with BRAFV600E mutations and mice bearing HT-29 xenografts were treated with vemurafenib in the absence or presence of PHA-665752. Cell viability and cycle phase were respectively examined by using the MTT and flow cytometry assay. Immunohistochemistry was conducted to detect the protein expression levels of hepatocyte growth factor (HGF), phosphorylated (p)-c-Met, p-AKT serine/threonine kinase (AKT) and p-extracellular signal-regulated kinase (p-ERK). The MTT assay demonstrated that the growth of RKO and HT-29 cells was inhibited by PHA-665752 in a time- and dose-dependent manner (P<0.05), however no significant suppressive effects were observed with vemurafenib. Relative to the PHA-665752 or vemurafenib stand-alone treatment groups, the combination of PHA-665752 and vemurafenib had a significant inhibitory effect on the proliferation of CRC cell lines (P<0.05). The mean tumor volume in mice treated with vemurafenib in combination with PHA 665752 was significantly smaller compared with those treated with only vemurafenib or PHA-665752 (P<0.05). Flow cytometry assay revealed that the G0/G1 phase frequency was significantly increased in the combination group compared with any other treatment groups (P<0.05). Immunohistochemistry demonstrated that vemurafenib in combination with PHA-665752 effectively induced the expression of p-c-Met, p-AKT and p-ERK, however had no effect on HGF. PMID- 29456740 TI - An obligatory anaerobic Salmonella typhimurium strain redirects M2 macrophages to the M1 phenotype. AB - A genetically engineered Salmonella typhimurium strain that may be applied in the medically useful therapeutic strategy of using bacterial agents to target breast cancer in a tumor-bearing nude mouse model has been previously reported. Furthermore, immune cell accumulation in breast tumor types has been observed, particularly distributed in regions surrounding the bacteria. M2 macrophages are associated with breast cancer aggressiveness, whereas M1 macrophages are prone to devouring bacteria and killing cancer cells. Therefore, this engineered tumor targeting salmonella strain was used in an attempt to reverse the phenotype of M2 macrophages into the M1 phenotype. Subsequent to the co-culture of M2 macrophages with the bacteria for a short time, >50% of the M2 macrophages were invaded by bacteria. These M2 macrophages exhibited a decreased expression of mannose receptor (an M2 phenotypic marker) and increased expression of human leukocyte antigen-antigen D related (an M1 phenotypic marker). The results of the present study indicated that differentiated M2 macrophages may be redirected into the M1 phenotype following exposure to the engineered bacteria stimulus. This effect may be a potential mechanism by which bacteria retard tumor growth. Thus, this engineered bacterium may be a useful candidate for targeting and redirecting M2 macrophages into the M1 phenotype. PMID- 29456741 TI - Overexpression of flavin-containing monooxygenase 5 predicts poor prognosis in patients with colorectal cancer. AB - The present study investigated the expression and clinical significance of flavin containing monooxygenase 5 (FMO5) in colorectal cancer (CRC). The expression of FMO5 was detected by immunohistochemistry in 208 colon cancer tissues and 8 normal colon tissues. Then, the correlations of FMO5 expression with several clinicopathological features were evaluated. FMO5 mRNA expression from The Cancer Genome Atlas dataset was assessed for further validation. In addition, the association of the expression of FMO5 with prognosis was further evaluated by Kaplan-Meier survival curves and Cox proportional hazards model. The FMO5 protein level in colon cancer tissues was significantly higher than that in normal colon tissues (P<0.001). Overexpression of FMO5 was associated with an advanced clinical stage of cancer (P=0.018) and lymph node metastasis (P=0.03). The TCGA dataset also demonstrated that FMO5 was upregulated in CRC with advanced clinical stage (P=0.047), lymph node metastasis (P=0.045) and distant metastasis (P=0.030). The Kaplan-Meier survival curves showed that higher FMO5 mRNA indicated a shorter overall survival in patients with CRC compared with a low expression of FMO5 (P=0.029). Cox proportional hazards regression revealed that a high FMO5 mRNA level served as an independent prognostic factor for patients with CRC (hazard ratio, 2.865; 95% confidence interval, 1.116-7.355; P=0.029). A high expression of FMO5 may serve roles in colorectal carcinogenesis and distant metastasis. FMO5 may be an independent predictive factor for the prognosis of CRC. PMID- 29456742 TI - miR302a inhibits the proliferation of esophageal cancer cells through the MAPK and PI3K/Akt signaling pathways. AB - MicroRNAs (miRNAs/miRs) are involved in the regulation of various types of cancer, either as oncogenes or tumor suppressors. miR302a has been reported that it could suppress tumor cell proliferation by inhibiting Akt in prostate cancer. The present study examined the effect of miR302a on proliferation and invasion in esophageal cancer cell lines. The expression levels of miR302a in esophageal cancer cell lines was determined by reverse transcription-polymerase chain reaction. Subsequently, miR302a mimics were transfected into esophageal cancer cells, and cell viability and invasion were assessed by MTT and Transwell assays. In addition, the effects of miR302a on the mitogen-activated protein kinase (MAPK) and phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt) signaling pathways were investigated by western blot analysis. The results revealed that miR302a expression was significantly decreased in the esophageal cancer cell lines compared with a healthy esophagus epithelium cell line. Upregulation of miR302a inhibited the proliferation and invasion of esophageal cancer cells, and decreased the phosphorylation of extracellular signal-regulated kinase 1/2 and Akt. Taken together, the results of the present study indicated that miR302a overexpression inhibited the proliferation and invasion of esophageal cancer cells through suppression of the MAPK and PI3K/Akt signaling pathways, indicating the potential value of miR302a as a treatment target for human esophageal cancer. PMID- 29456743 TI - IL-10 in the microenvironment of HNSCC inhibits the CpG ODN induced IFN-alpha secretion of pDCs. AB - It has been shown that head and neck squamous cell carcinoma (HNSCC) are infiltrated by plasmacytoid dendritic cells (pDCs). The HNSCC TH2 biased microenvironment leads to strong alterations of the cellular functions of pDC and thus impairs the initiation and function of adequate immune responses. In this work we comprehensively analyzed the capacity of CpG-oligonucleotides to activate interferon (IFN)-alpha secretion of human pDC in the presence of HNSCC. IFN-alpha secretion was measured using the ELISA Technique. Class A CpG dinucleotide 2216 was used in different concentrations and time frames to stimulate the IFN-alpha production of human pDC from peripheral blood in the absence and presence of the HNSCC microenvironment. To elucidate single components that might induce the reduction of IFN-alpha secretion, pDC were exposed to different concentrations of HNSCC relevant cytokines such as IL-6, IL-8 and IL-10. In accordance to former experiments we found that HNSCC micro milieu severely depresses up to 75% of IFN alpha secretion capacity of pDCs, if the stimulating Class A CpG 2216 is added to the culture. Preincubation of HNSCC supernatant leads to unrestorable reduction of IFN-alpha secretion in pDC and can not be restored by CpG 2216. Incubation of pDCs with single cytokines relevant for cancer progression within the HNSCC micro milieu show that IL-6 or IL-8 have no influence on the IFN-alpha secretion in pDCs, whereas IL-10 massively impairs the secretion in a dose dependent manner. This effect can be potentiated by synergistic incubation with IL-6 and can be abrogated by blocking antibodies to the IL-10 receptor. Interestingly, incubation with IL-10 is not the only factor that impairs the IFN-alpha secretion, as incubation with the whole HNSCC supernatant is even more effective in reducing the secretion, implying that additional factors play a role. We conclude that restoration of HNSCC induced TH2 bias could be improved by the inhibition of immune cell cytokine receptors in addition to immunostimulating approaches with CpG motifs. PMID- 29456745 TI - Sp5 negatively regulates the proliferation of HCT116 cells by upregulating the transcription of p27. AB - The Wnt signaling pathway is aberrantly activated in the majority of human colorectal tumors. beta-catenin, a key component of the Wnt signaling pathway, interacts with the T-cell factor/lymphoid enhancer-binding factor family of transcription factors and activates transcription of Wnt target genes. Sp5 is one of the Wnt target genes, and its expression is commonly upregulated in colon cancer cells. The present study demonstrates that the expression of Sp5 is not upregulated in the colon cancer cell line HCT116, in which Wnt signaling is constitutively activated. Furthermore, the results demonstrate that Sp5 has the potential to inhibit cell proliferation through upregulation of the cell cycle inhibitor p27. These findings suggest that HCT116 cells downregulate Sp5 to avoid p27-mediated growth arrest. PMID- 29456744 TI - Cardamonin enhances the anti-proliferative effect of cisplatin on ovarian cancer. AB - The mammalian target of rapamycin (mTOR) is well-known as a promising therapeutic target in various cancer cells. mTOR activation decreases the sensitivity of ovarian cancer to cisplatin. Cardamonin inhibits the proliferation of various cancer cells by mTOR suppression. The present study examined whether cardamonin combined with cisplatin is efficacious for the anti-proliferation of ovarian cancer cells. The anti-proliferative effect was determined by MTT and cell cycle assays. Activation of the mTOR signal pathway and the expression of anti apoptotic proteins were evaluated by western blot analysis. Cardamonin significantly enhanced the effects of cisplatin on cell proliferation and cell cycle progression. The expression of B cell lymphoma-2, X-linked inhibitor of apoptosis protein and Survivin was significantly decreased following combination treatment. Furthermore, the activation of mTOR and its downstream 70 kDa ribosomal protein S6 kinase was inhibited by cardamonin. These results demonstrated that the combinatorial effects of cardamonin and cisplatin on anti proliferation were enhanced by suppressing the expression of anti-apoptotic proteins and activation of mTOR in ovarian cancer cells.

PMID- 29456747 TI - Clavicle fracture nonunion in the paediatric population: a systematic review of the literature. AB - Aims: Clavicle fracture nonunions are extremely rare in children. The aim of this systematic review was to assess what factors may predispose children to form clavicle fracture nonunions and evaluate the treatment methods and outcomes. Methods: We performed a systematic review according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, aiming to find papers reporting clavicle fracture nonunion in children under the age of 18 years. Data was collected on patient demographics, fracture type, mechanism of injury (MOI), surgical intervention and reported outcome. Two independent reviewers evaluated all the data. Results: A total of 13 articles reporting 21 cases of clavicle fracture nonunion were identified. The mean age at time of injury was 11.4 years (4 to 17). Falls were the most common MOI. The majority of nonunions occurred after displaced fractures on the right side. Six were refractures. Mean time of presentation following injury was 13.5 months (4 to 60). In all, 16 were treated surgically. Radiographic union was eventually achieved in 12 cases, with functional outcome satisfactory in all cases. Conclusion: Clavicle nonunion is an extremely rare but possible complication in children. The majority occur after displaced right-sided fractures or refractures and present around one year after injury. Surgical fixation provides good radiographic healing and functional outcomes.

AB - Purpose: Acute compartment syndrome often requires additional surgery to achieve wound closure. Little information exists regarding the expected number of surgeries, techniques and complications after closure in paediatric patients. Methods: A retrospective chart review identified patients treated for acute compartment syndrome at four hospitals over a ten-year period. The cause of injury, type of dressing, number of surgeries, type of closure and complications were recorded. Results: In all, 32 patients (mean 10.9 years, 1 to 17) who underwent 18 lower and 14 upper extremity fasciotomies met inclusion criteria. Definitive wound closure technique was delayed primary in 72%, split thickness skin graft in 25%, and primary in 3% of patients. Closure required a mean 2.4 surgeries (0 to 4) over a mean 7.7 days (0 to 34). Days to closure and number of surgeries required were not significantly affected by mechanism of injury, fasciotomy location or type of dressing used. A total of 23.1% of patients with upper extremity and 0% with lower extremity fasciotomies had concerns about the scar appearance. Other complications included neurapraxia (6.7%), stiffness (6.7%), swelling (3.3%), scar pain (3.3%) and weakness (3.3%). Conclusions: The most common complication after paediatric compartment syndrome is an unpleasant scar. Wound closure after upper or lower extremity fasciotomies in paediatric patients requires a split thickness skin graft in approximately one in four patients. However, avoiding a skin graft does not guarantee the absence of cosmetic concerns, which are more likely following upper extremity fasciotomies. Level of Evidence: IV. PMID- 29456749 TI - The effect of canal fill on paediatric femur fractures treated with titanium elastic nails. AB - Purpose: Traditional teaching for fixation of paediatric femur fractures recommends 80% nail diameter/medullary canal diameter ratio (ND/MCD) for successful maintenance of reduction. Prior studies have investigated this with stainless steel Enders nails. Our aim was to assess the impact of ND/MCD on maintenance of reduction and malunion rates in paediatric femur fractures treated with flexible intramedullary nails (FINs). Methods: Retrospective data was collected on all paediatric patients treated with FINs for diaphyseal femur fractures at a single tertiary care institution over a ten-year period. Patients with co-morbidities affecting bone quality were excluded. Patients were subdivided into groups based on ND/MCD. Results: A total of 66 patients met inclusion criteria. Mean ND/MCD was 76.3% (32.9% to 98.8%, SD 14.3). In all, 50% (n = 33/66) of patients had > 80% ND/MCD, and only 13.6% (n = 9/66) of patients had less than 60% ND/MCD. When controlling for fracture stability, ND/MCD had no correlation with mean shortening (p = 0.07) There was no correlation between ND/MCD and angulation in the sagittal (p = 0.96) or coronal plane (p = 0.20). Three patients fit malunion criteria. ND/MCD for these patients were 40%, 67% and 79%. Conclusion: There was no correlation between ND/MCD and shortening or malangulation. The majority of patients in this series with less than 80% fill with FIN healed within acceptable parameters. Level of Evidence: III. PMID- 29456750 TI - Paediatric tibial shaft fractures treated by open reduction and stabilization with monolateral external fixation. AB - Purpose: Elastic stable intramedullary nailing is increasingly used for surgical treatment of tibial shaft fractures, but frequently requires immobilization and delayed full weight-bearing. Therefore, external fixation remains interesting. The aim was to report clinico-radiological outcomes of monolateral external fixation for displaced and unstable tibial shaft fractures in children. Methods: All tibial fractures consecutively treated by monolateral external fixation between 2008 and 2013 were followed. Inclusion criteria included skeletal immaturity and closed and open Gustilo I fractures caused by a direct impact. Patients were seen until two years postoperatively. Demographics, mechanism of injury, surgical data and complications were recorded. Anteroposterior and lateral side radiographs were performed at each visit. Full-limb 3D reconstructions using biplanar stereroradiography was performed for final limb length and alignment measures. Results: A total of 45 patients (mean age 9.7 years +/- 0.5) were included. In all, 17 were Gustilo I fractures, with no difference between open and closed fractures for any data. Mean time to full weight bearing was 18.2 days +/- 0.7. After 15 days, 39 patients returned to school. Hardware removal (mean time to union 15.6 weeks +/- 0.8) was performed during consultation under analgesic gas. There were no cases of nonunion. No fracture healed with > 10 degrees of angulation (mean 5.1 degrees +/- 0.4 degrees ). Leg-length discrepancy > 10 mm was found for six patients. Conclusions: This procedure can be a safe and simple surgical treatment for children with tibial shaft fractures. Few complications and early return to school were reported, with the limitations of non-comparative study. Level of Evidence: IV. PMID- 29456751 TI - Cannulated screw versus Kirschner-wire fixation for Milch II lateral condyle fractures in a paediatric sawbone model: a biomechanical comparison. AB - Purpose: Lateral condyle fractures of the humerus are common in the paediatric population, accounting for up to 20% of elbow fractures. Traditional management involves internal fixation with Kirschner (K)-wires, however, this has been associated with complications and insufficiently rigid fixation. Recently, cannulated screws have been proposed as a more stable method of fixation. While cannulated screws have been thought to allow earlier range of movement and shorten time to union, data regarding the biomechanical performance and optimal screw placement is scarce. We hypothesize that cannulated screw fixation is superior to K-wire fixation and screw placement can enhance the stability of the construct. Methods: Paediatric humerus sawbones with Milch II fractures were fixed with one of three methods. Fractures were reduced with either a single cannulated screw either through the centre of the capitellum (oblique), or placed up the lateral column across the growth plate (lateral), or fixed with two K wires. Fixed sawbone fractures were then mechanically tested in two directions simulating in vivo forces. Results: The lateral screw construct had a higher maximum force to failure, higher stiffness and absorbed higher energy as compared with the K-wire fixation and oblique screw under an anterior force. When loaded from the posterior direction, only the lateral column screw was better than K wire fixation. Conclusions: Screw fixation is a biomechanically effective alternative to K-wire fixation, especially when placed up the lateral column of the distal humerus. Further clinical studies are required before transcapitellar screw fixation can be adopted. PMID- 29456752 TI - Treatment of the overriding fifth toe: Butler's arthroplasty is a good option. AB - Purpose: The overriding fifth toe is a congenital triplane deformity that may cause aesthetic and functional concerns in children and adolescents. This study aims to evaluate the results obtained when using Butler's arthroplasty to treat this forefoot deformity. Methods: We performed a retrospective study, including all patients undergoing Butler's arthroplasty from January 1995 to December 2012. Clinical records were reviewed to determine age at date of surgery, gender, laterality, preoperative symptoms, success of deformity correction, postoperative pain, scarring, need for adapted shoe, rates of complications and recurrence. Patient satisfaction was evaluated through a telephone interview. All p-values < 0.05 were considered statistically significant. Results: A total of 21 patients were included in this study, the majority of which were male (57%), with a mean follow-up of 12 months (1 to 52). In the evaluation of the residual deformity (18 patients), 72% had excellent results, 17% good and 11% poor results. One patient had a keloid scar, three patients reported pain and three patients required adapted footwear. There was a partial recurrence of the deformity in three cases. The majority of patients (78%) were satisfied with the surgery. There was no statistically significant difference in terms of results, when comparing patients older and younger than seven years of age (p = 0.46). Conclusions: Butler's operation is effective and safe in the treatment of the overriding fifth toe, yielding good functional results and patient satisfaction, with low rate of complications.

AB - Purpose: Describe the surgical technique of talocalcaneal coalition resection using live CT navigation. Methods: A ten-year-old female with left talocalcaneal coalition hindfoot pain refractory to conservative management underwent surgical coalition resection using live CT navigation. The procedure and discussion of this technique is described in detail. Results: With minimal radiation exposure to the patient, CT navigation for this complex talocalcaneal coalition was both helpful and potentially timesaving by allowing immediate localization and guided resection of the coalition. Conclusion: In the case of a complex subtalar coalition resection, CT navigation poses minimal patient radiation exposure and allows immediate localization and guided resection of the coalition. Level of Evidence: Level V. PMID- 29456754 TI - Management of osteonecrosis of the femoral head in children with sickle cell disease: results of conservative and operative treatments at skeletal maturity. AB - Purpose: Sickle cell disease (SCD) is the most common cause of femoral head osteonecrosis (ONFH) during childhood with an overall prevalence of 10%. In children, spontaneous revascularization can occur, as in Legg-Calve-Perthes disease. Consequently, the aim of treatment is to restore proper hip containment to prevent joint arthritis. This is the first study reporting long-term results at skeletal maturity of non-operative and surgical treatments for ONFH in SCD children. Methods: All children with ONFH due to SCD were retrospectively reviewed. At initial evaluation, extension of osteonecrosis was radiographically defined using Catterall, lateral pillar Herring and Ficat classifications. Subluxation of the femoral head with Reimers migration index > 30% required surgical treatment including femoral varus osteotomy and/or pelvic osteotomies. Conservative treatment including non-weight bearing and physiotherapy was performed in the remaining cases. Outcomes were assessed at skeletal maturity using the Harris Hip Score (HHS) and the Stulberg classification. Total hip arthroplasty and Stulberg 5 were defined as failures. Results: A total of 25 hips in 17 patients were included (mean follow-up 7.5 years SD 3.4). Mean age at diagnosis was 11.4 years SD 2.9. In all, 15 hips (60%) were classified Catterall 3 and 4 and Herring B and C. A total of 13 patients (52%) underwent surgical treatment. At skeletal maturity, mean HHS was good (81 SD 17), 12 hips (48%) were classified Stulberg 1 and 2, seven hips (28%) were classified Stulberg 3 and 4. Conclusion: Both treatments led to good functional results with 75% of congruent hips at skeletal maturity. Level of Evidence: IV. PMID- 29456755 TI - Preliminary results of an anteverting triple periacetabular osteotomy for the treatment of hip instability in Down syndrome. AB - Purpose: To investigate the outcomes of an anteverting triple periacetabular osteotomy for the treatment of hip instability in skeletally immature patients with Down syndrome. Methods: We evaluated 16 patients (21 hips) with Down syndrome and hip instability who underwent an anteverting triple periacetabular osteotomy between 2007 and 2016. There were nine females and seven males with an average age of 7.4 years SD 2.0. We assessed the level of hip pain, gait ability and clinical stability at a minimum of one year after surgery. Radiographic evaluation included pre- and postoperative lateral centre-edge angle (LCEA), Tonnis acetabular angle and extrusion index. Result: After an average follow-up of 4.1 years SD 2.6, 20 of 21 hips (95%) remained clinically stable. In all, 12 of 16 (75%) patients had a full gait without a major limp, but three patients (19%) had a persistent limp. Of the 21 procedures, one hip (5%) was considered a failure due to persistent instability. There was a mean increase of 18.3o SD 15.3o of the LCEA (p < 0.001); a mean decrease of 15.2o SD 11.6o (p < 0.001) for the Tonnis angle and the extrusion index had a mean decrease of 0.27 SD 0.20 (p < 0.001). The most common complications were minor and included nonunion of the pubis or ischium (24%) and stress fractures of the pubis and ischium (14%). Only one patient required unplanned surgery for the treatment of an infection; which was considered a major complication. Conclusion: The anteverting triple periacetabular osteotomy provided global deformity correction and achieved hip stability in 95% of the hips after a mean follow-up of 4.1 years.

AB - Purpose: Previous studies have suggested an association between increased thoracic kyphosis and neural axis abnormalities in patients with adolescent idiopathic scoliosis (AIS). However, the basis for this finding is unclear, and this association has been mainly noted in retrospective studies on a non consecutive series of patients. The purpose of this study was to assess the relationship between thoracic kyphosis and neural axis abnormalities in patients with AIS. Methods: We studied a consecutive series of AIS patients treated with spinal fusion. Thoracic kyphosis (T2 to T12) was measured from preoperative lateral radiographs. All patients underwent a spine magnetic resonance imaging (MRI) prior to surgery, and MRI reports were reviewed to determine the presence of neural axis abnormalities. Statistical analyses included descriptive statistics and chi-squared analysis. Results: This study included 210 patients with AIS. There were no significant differences in age or gender between patients with thoracic hypokyphosis (kyphosis < 20 degrees ), normal thoracic kyphosis (kyphosis 20 degrees to 40 degrees ) and thoracic hyperkyphosis (kyphosis > 40 degrees ) (p > 0.05). Neural axis abnormalities were present in 17.9% of patients with thoracic hypokyphosis, 9.8% of patients with normal thoracic kyphosis and 13.6% of patients with thoracic hyperkyphosis (p = 0.60). There were no significant differences in rates of Chiari malformation, syrinx, intra-spinal masses and other central nervous system abnormalities between groups (p > 0.05). Conclusions: Thoracic kyphosis was not associated with neural axis abnormalities in our consecutive series of patients with AIS. Increased thoracic kyphosis may not be a reliable indicator for the presence of neural axis abnormalities in patients with AIS. Level of Evidence: IV. PMID- 29456757 TI - The natural history of spinal deformity in patients with Coffin-Lowry syndrome. AB - Purpose: Little is known about the natural history of spinal deformities in Coffin-Lowry syndrome (CLS). Our goal was to evaluate the spinal deformity progression and clinical impact. Methods: In this institutional review board approved study, we performed a multinational retrospective review of six male CLS patients, aged 13 to 22 years at final follow-up, for a mean of 7.25 years (3 to 13). Results: All showed delayed skeletal maturity. Three had calcifications of their lower cervical ligamentum flavum, all experienced neural axis abnormalities, including lower extremity weakness, numbness and tingling and in one, quadriparesis. Only two were ambulatory at final follow-up.All had significant spinal abnormalities, including severe progressive thoracic lordosis, thoracolumbar kyphosis and scoliosis. All had undergone spinal fusion or were being evaluated for surgery. Conclusion: CLS is a rare X-linked mutation in the RSK2 gene, affecting between 1/50 000 to 100 000 people. There are two reports in the literature of patients with calcifications of their ligamentum flavum. Both had neural axis abnormalities and one had acute onset quadriplegia. Analysis of their ligamentum flavum found abundant central calcifications. Despite our small cohort we found 50% had calcifications and 100% had neurologic consequences associated with those calcifications. There was a 100% rate of deformity progression.They all exhibited delay in skeletal maturity, which mandates longer follow-up and has implications for surgical planning.From our cohort and literature review, the natural history of CLS supports frequent patient evaluation and a lower threshold for correction of spinal deformities. Aiming to avoid spinal cord compression and improve or avoid neurological deterioration. Level of Evidence: IV - retrospective study. PMID- 29456758 TI - Binary and analogue markers of skeletal maturity: clinical utility of the thenar and plantar sesamoids. AB - Purpose: We investigate the thenar and plantar sesamoids as markers of skeletal maturity, and grade appearance using two scales, a binary system (absent or present), and an analogue system that relies upon judging regular changes in morphological appearance. Methods: We studied 94 healthy children (49 female and 45 male patients) between ages three and 18 years who had approximately 700 serially acquired sets of radiographs and physical examinations. The children had at least annual radiographs taken of the left hand and left foot. Velocity of growth was calculated and curves were fit to a cubic spline model to determine age of maximum height velocity, or peak height velocity (PHV). Appearance of the plantar and thenar sesamoids was recorded using a binary system classifying the sesamoids as absent or present and an analogue system classifying the sesamoid as absent, present as a small ossification centre or larger than a small ossification centre. Results: The plantar sesamoids appear 1.67 years before PHV and reach mature size 1.02 years after PHV. The thenar sesamoids appear 0.32 years before PHV and reach mature size 2.25 years after PHV. The plantar sesamoids are present and thenar sesamoids are absent at a mean 1.5 years prior to PHV. No patients had the thenar sesamoids present while the plantar sesamoids were absent. Conclusion: As binary markers, when the plantar and thenar sesamoids are considered together it is possible to localize maturity. As analogue markers, they offer more information. The sesamoids also allow clarification of the calcaneal and Sanders stages. Level of Evidence: Not Applicable. PMID- 29456759 TI - Ossification of the phalanges of the foot and its relationship to peak height velocity and the calcaneal system. AB - Purpose: There are multiple skeletal maturity grading systems, but none of them utilizes the phalanges of the foot. To minimize radiation, it would be ideal if one could assess the skeletal maturity of a foot based on bones seen on routine foot radiographs, if guided growth is being considered as a treatment option. We developed a system that correlates changes of the appearance of the foot phalanges to peak height velocity (PHV) and the recently described calcaneal apophyseal ossification grading system. Methods: We selected 94 children from the Bolton-Brush study, each with consecutive radiographs from age ten to 15 years old. Using the anteroposterior view, we analyzed the ossification patterns of the phalanges and developed a six-stage system. We then determined the PHV for each subject and defined its relationship with our system. Our system was then compared with the previously established calcaneal system. Results: We calculated an Intraclass correlation coefficient (ICC) range of 0.957 to 0.985 with a mean of 0.975 and interclass reliability coefficient of 0.993 indicating that this method is reliable and consistent. Our system showed no significant difference between gender with respect to PHV, which makes it a reliable surrogate for determining bone age in paediatric and adolescent patients. Conclusions: Our system has a strong association with the calcaneal system. It is a simple six stage system that is reliable and correlated more strongly with PHV than chronological age. The system requires knowledge of the ossification markers used for each stage but is easily used in a clinical setting. PMID- 29456760 TI - Guided growth: preliminary results of a multinational study of 967 physes in 537 patients. AB - Background: Guided growth by tension band plating is commonly used to correct coronal plane deformity. The purpose of this study was to measure the effect and further define parameters that influence results in coronal plane deformity around the knee. Methods: The retrospective multicentre study included data on 967 physes in 537 patients, with an average follow-up of 16 months after plate insertion. Alignment analysis was compared preoperatively and in at least two measurements postoperatively, as well as with parameters that influence the rate and amount of correction. Results: Average age at plate implantation was 11.35 years (SD 3.29).Of those with femoral deformities, 85% of the patients finished the treatment and of those, 70% were corrected to standard alignment, while 14% have not yet achieved correction, and are still growing.Of those with tibial deformities, 75% of the patients finished the treatment and of those 80% were corrected to standard alignment, while 25% have not yet achieved correction and are still growing.The calculated rate of correction was 0.77 degrees /month for the femur and 0.79 degrees /month for the tibia.In terms of complications, the overall rate of infection was 1.48%. In three patients (0.55%) screw breakage was recorded.Factors found to significantly influence the amount of correction were age at plate implantation and direction of deformity. Conclusion: Temporary hemiepiphysiodesis takes the advantage of physiological physeal growth to effectively treat angular deformities. Success of treatment is influenced by the age of the patient at plate implantation and direction of deformity. Level of Evidence: IV. PMID- 29456761 TI - Effects of a telescopic intramedullary rod for treating patients with osteogenesis imperfecta of the femur. AB - Purpose: To introduce a new model of telescopic intramedullary rod (TIR), evaluate its effects on treating patients presenting with moderate and severe osteogenesis imperfecta (OI) and to compare the findings with those of other telescopic rods. Methods: A total of 21 patients (nine girls and 12 boys; mean age at first operation, 6.6 years, 1.52 to 13.18) who underwent 52 femoral operations were monitored during a mean of 9.96 years (3.39 to 14.54). Patient characteristics, telescoping rod capability and its complications were examined. Results: According to the Sillence classification, we investigated one patient with type I, nine with type III and 11 with type IV OI. Revision rates at up to five years (36%) were inferior to those found for the Fassier-Duval rod (46%). The main cause of revision was fracture (15 patients), followed by rod migration (nine), and infection (two). The rod exhibited higher telescopic capacity in boys than girls. Type III most commonly required an operation; the age group with the highest number of procedures was five to ten years. Male migration was the main cause of rod migration. Conclusion: The TIR has a satisfactory cost-benefit ratio with less complication rates and low production costs. The TIR is a feasible alternative to the commonly used Fassier-Duval rod.

AB - Ozone within deep convective clouds is controlled by several factors involving photochemical reactions and transport. Gas-phase photochemical reactions and heterogeneous surface chemical reactions involving ice, water particles, and aerosols inside the clouds all contribute to the distribution and net production and loss of ozone. Ozone in clouds is also dependent on convective transport that carries low troposphere/boundary layer ozone and ozone precursors upward into the clouds. Characterizing ozone in thick clouds is an important step for quantifying relationships of ozone with tropospheric H2O, OH production, and cloud microphysics/transport properties. Although measuring ozone in deep convective clouds from either aircraft or balloon ozonesondes is largely impossible due to extreme meteorological conditions associated with these clouds, it is possible to estimate ozone in thick clouds using backscattered solar UV radiation measured by satellite instruments. Our study combines Aura Ozone Monitoring Instrument (OMI) and Microwave Limb Sounder (MLS) satellite measurements to generate a new research product of monthly-mean ozone concentrations in deep convective clouds between 30 degrees S to 30 degrees N for October 2004 - April 2016. These measurements represent mean ozone concentration primarily in the upper levels of thick clouds and reveal key features of cloud ozone including: persistent low ozone concentrations in the tropical Pacific of ~10 ppbv or less; concentrations of up to 60 pphv or greater over landmass regions of South America, southern Africa, Australia, and India/east Asia; connections with tropical ENSO events; and intra-seasonal/Madden-Julian Oscillation variability. Analysis of OMI aerosol measurements suggests a cause and effect relation between boundary layer pollution and elevated ozone inside thick clouds over land-mass regions including southern Africa and India/east Asia. PMID- 29456763 TI - Causal effect of smoking on DNA methylation in peripheral blood: a twin and family study. AB - Background: Smoking has been reported to be associated with peripheral blood DNA methylation, but the causal aspects of the association have rarely been investigated. We aimed to investigate the association and underlying causation between smoking and blood methylation. Methods: The methylation profile of DNA from the peripheral blood, collected as dried blood spots stored on Guthrie cards, was measured for 479 Australian women including 66 monozygotic twin pairs, 66 dizygotic twin pairs, and 215 sisters of twins from 130 twin families using the Infinium HumanMethylation450K BeadChip array. Linear regression was used to estimate associations between methylation at ~ 410,000 cytosine-guanine dinucleotides (CpGs) and smoking status. A regression-based methodology for twins, Inference about Causation through Examination of Familial Confounding (ICE FALCON), was used to assess putative causation. Results: At a 5% false discovery rate, 39 CpGs located at 27 loci, including previously reported AHRR, F2RL3, 2q37.1 and 6p21.33, were found to be differentially methylated across never, former and current smokers. For all 39 CpG sites, current smokers had the lowest methylation level. Our study provides the first replication for two previously reported CpG sites, cg06226150 (SLC2A4RG) and cg21733098 (12q24.32). From the ICE FALCON analysis with smoking status as the predictor and methylation score as the outcome, a woman's methylation score was associated with her co-twin's smoking status, and the association attenuated towards the null conditioning on her own smoking status, consistent with smoking status causing changes in methylation. To the contrary, using methylation score as the predictor and smoking status as the outcome, a woman's smoking status was not associated with her co-twin's methylation score, consistent with changes in methylation not causing smoking status. Conclusions: For middle-aged women, peripheral blood DNA methylation at several genomic locations is associated with smoking. Our study suggests that smoking has a causal effect on peripheral blood DNA methylation, but not vice versa.

AB - Background: Elucidation of epigenetic alterations in bladder cancer will lead to further understanding of the biology of the disease and hopefully improved therapies. Our aim was to perform an integrative epigenetic analysis of invasive urothelial carcinoma of the bladder to identify the epigenetic abnormalities involved in the development and progression of this cancer. Methods: Pre processed methylation data and RNA-seq data were downloaded from The Cancer Genome Atlas (TCGA) and processed using the R package TCGA-Assembler. An R package MethylMix was used to perform an analysis incorporating both methylation and gene expression data on all samples, as well as a subset analysis comparing patients surviving less than 2 years and patients surviving more than 2 years. Genes associated with poor prognosis were individually queried. Pathway analysis was performed on statistically significant genes identified by MethylMix criteria using ConsensusPathDB. Validation was performed using flow cytometry on bladder cancer cell lines. Results: A total of 408 patients met all inclusion criteria. There were a total of 240 genes differentially methylated by MethylMix criteria. Review of individual genes specific to poor-prognosis patients revealed the majority to be candidate tumor suppressors in other cancer types. Pathway analysis showed increase in methylation of genes involved in antioxidant pathways including glutathione and NRF2. Genes involved in estrogen metabolism were also hypermethylated while genes involved in the EGFR pathway were found to be hypomethylated. EGFR expression was confirmed to be elevated in six bladder cancer cell lines. Conclusions: In patients with invasive urothelial carcinoma, we found differential methylation in patients with better and worse prognosis after cystectomy. Differentially methylated genes are involved in many relevant oncologic pathways, including EGFR and antioxidant pathways, that may be a target for therapy or chemoprevention. PMID- 29456765 TI - Peripheral blood epi-signature of Claes-Jensen syndrome enables sensitive and specific identification of patients and healthy carriers with pathogenic mutations in KDM5C. AB - Background: Claes-Jensen syndrome is an X-linked inherited intellectual disability caused by mutations in the KDM5C gene. Kdm5c is a histone lysine demethylase involved in histone modifications and chromatin remodeling. Males with hemizygous mutations in KDM5C present with intellectual disability and facial dysmorphism, while most heterozygous female carriers are asymptomatic. We hypothesized that loss of Kdm5c function may influence other components of the epigenomic machinery including DNA methylation in affected patients. Results: Genome-wide DNA methylation analysis of 7 male patients affected with Claes Jensen syndrome and 56 age- and sex-matched controls identified a specific DNA methylation defect (epi-signature) in the peripheral blood of these patients, including 1769 individual CpGs and 9 genomic regions. Six healthy female carriers showed less pronounced but distinctive changes in the same regions enabling their differentiation from both patients and controls. Highly specific computational model using the most significant methylation changes demonstrated 100% accuracy in differentiating patients, carriers, and controls in the training cohort, which was confirmed on a separate cohort of patients and carriers. The 100% specificity of this unique epi-signature was further confirmed on additional 500 unaffected controls and 600 patients with intellectual disability and developmental delay, including other patient cohorts with previously described epi-signatures. Conclusion: Peripheral blood epi-signature in Claes-Jensen syndrome can be used for molecular diagnosis and carrier identification and assist with interpretation of genetic variants of unknown clinical significance in the KDM5C gene. PMID- 29456766 TI - Letter to the editor: blood processing and sample storage have negligible effects on methylation. AB - DNA methylation is a dynamic epigenetic mechanism. Researchers aiming to assess archived DNA samples are expressing concern about the effect of technical factors on methylation, as this may confound results. We reviewed recent reports examining this issue in blood samples and concluded that variation in collection, storage, and processing of blood DNA confers negligible effects on both global methylation and methylation status of specific genes. These results are concordant with studies that have investigated the effect of sample storage and processing on methylation in other tissues, such as tumour, sperm, and placenta samples. PMID- 29456767 TI - Biochemical Characterization of Two Clinically-Relevant Human Fumarase Variants Defective for Oligomerization. AB - Background: Fumarase, a significant enzyme of energy metabolism, catalyzes the reversible hydration of fumarate to L-malate. Mutations in the FH gene, encoding human fumarase, are associated with fumarate hydratase deficiency (FHD) and hereditary leiomyomatosis and renal cell cancer (HLRCC). Fumarase assembles into a homotetramer, with four active sites. Interestingly, residues from three of the four subunits within the homotetramer comprise each active site. Hence, any mutation affecting oligomerization is predicted to disrupt enzyme activity. Methods: We constructed two variants of hexahistidine-tagged human recombinant fumarase, A308T and H318Y, associated with FHD and HLRCC, respectively. Both Ala308 and His318 lie within the fumarase intersubunit interface. We purified unmodified human fumarase and the two variants, and analyzed their enzymatic activities and oligomerization states in vitro. Results: Both variants showed severely diminished fumarase activity. Steady-state kinetic analysis demonstrated that the variants were largely defective due to decreased turnover rate, while displaying Km values for L-malate similar to unmodified human recombinant fumarase. Blue native polyacrylamide gel electrophoresis and gel filtration experiments revealed that each variant had an altered oligomerization state, largely forming homodimers rather than homotetramers. Conclusion: We conclude that A308T and H318Y render human fumarase enzymatically inactive via defective oligomerization. Therefore, some forms of FHD and HLRCC can be linked to improperly folded quaternary structure. PMID- 29456768 TI - Hospital Mortality Among Elderly Patients Admitted With Neurological Disorders Was Not Predicted by any Particular Diagnosis in a Tertiary Medical Center. AB - Background: Neurological disorders (NDs) are associated with high hospital mortality. We aimed to identify predictors of hospital mortality among elderly inpatients with NDs. Methods: Patients aged >=60 years admitted to the hospital between January 1, 2009 and December 31, 2010 with acute NDs, chronic NDs as underpinnings of acute clinical disorders, and neurological complications of other diseases were studied. We analyzed demographic data, NDs, and comorbidities as independent predictors of hospital mortality. Logistic regression was performed for multivariable analysis. Results: Overall, 1540 NDs and 2679 comorbidities were identified among 798 inpatients aged >= 60 years (mean 75.8+/ 9.1). Of these, 54.5% were female. Diagnostic frequency of NDs ranged between 0.3% and 50.8%. Diagnostic frequency of comorbidities ranged from 5.6% to 84.5%. Comorbidities varied from 0 to 9 per patient (90% of patients had >=2 comorbidities), mean 3.2+/-1.47(CI, 3.1-3.3). Patients with multimorbidities presented with a mean of 4.7+/-1.7 morbidities per patient. Each ND and comorbidity were associated with high hospital mortality, producing narrow ranges between the lowest and highest incidences of death (hospital mortality = 18%) (95% CI, 15%-21%). After multivariable analysis, advanced age (P<0.001) and low socioeconomic status (P=0.003) were recognized as predictors of mortality, totaling 9% of the variables associated with hospital mortality. Conclusion: Neither a particular ND nor an individual comorbidity predicted hospital mortality. Age and low socioeconomic class accounted for 9% of predictors. We suggest evaluating whether functional, cognitive, or comorbidity scores will improve the risk model of hospital mortality in elderly patients admitted with ND. PMID- 29456769 TI - A Case of Schwannoma of the Submandibular Region. AB - Background: We herein described a rare case of schwannoma of the hypoglossal nerve in the submandibular region with diagnostic imaging and histopathological findings. Case Report: A 31-years-old woman has had a palpable firm, rubbery, freely mobile mass in the submandibular region. Of imaging, MR images showed homogeneous isointensity on T1-weighted imaging (T1-WI), heterogeneous hypointensity on T2-WI, heterogeneous hyperintensity on short T1 inversion recovery (STIR), and heterogeneous enhancement on contrast-enhanced T1-WI. A clear capsule was observed on the margin and showed hypointense on T2-WI. Dynamic MRI showed heterogeneous gradual increased enhancement. The uptake of contrast medium was regionally slow. Diagnostic imaging using CT and MRI was suspected of salivary gland tumor or neurogenic tumor. In consideration of imaging diagnosis, a pleomorphic adenoma or a schwannoma was suspected. Final diagnosis was confirmed on the basis of histopathological finding and intraoperative findings. Conclusion: 1. Histopathologic examination is inevitable, because MR findings are not specific.2. Schwannomas were said to have specific MRI properties, including specific signs (split-fat sign, fascicular sign, target sign). However, they are not always observed.3. This case confirmed the differential diagnosis on the basis of the intraoperative finding that the tumor was continuous with the hypoglossal nerve. PMID- 29456770 TI - Recurrent Oral Eosinophilic Ulcers of the Oral Mucosa. A Case Report. AB - Objective: This article describes a case of an Oral Eosinophilic Ulcer (OEU) in an otherwise healthy 31-year-old white woman. Introduction: The importance of reporting this case was the presence of recurrent episodes with lesions appearing in different areas of the oral mucosa, a type of manifestation not commonly associated with this disease. A typical manifestation of OEU occurs as a single ulceration that goes into healing after an incisional biopsy, a procedure usually required for a proper diagnosis of the disease. In spite of trauma being suggested as the main culprit of OEU, the exact pathogenesis mechanism of this disease remains controversial. Case report: The pattern of the present case contradicts the usually common course of the disease, as the patient had experienced many recurrent episodes for almost 2.5 years, with the recurrences occurring even after biopsies performed during some of the relapses. Differential diagnosis included recurrent aphthous stomatitis, recurrent intra-oral herpes, autoimmune disease, Crohn's disease and malignancy. Conclusion: Fortunately, the patient has been free of any recurrences for 1.5 years since the last biopsy was taken at the time she came to our clinic seeking treatment. PMID- 29456771 TI - Pulpal and Periodontal Tissues Changes Associated with Le Fort I and Sagittal Split Ramus Osteotomies: A review. AB - Introduction: Le Fort I and sagittal split ramus osteotomies are the most commonly performed orthognathic surgery procedures on the maxilla and mandible, respectively. Techniques: Despite progress in the techniques, these procedures may still be associated with morbidity, expressed as inflammation, inadequate bony union, periodontal damages or in extreme cases even total bone loss. Discussion: Through a comprehensive review of the literature, the influences of maxillary and mandibular surgery on Pulpal Blood Flow (PBF), pulp sensitivity and pulp vitality are examined. Moreover, adverse effects of maxillary surgery on tooth color and periodontal tissues are also reported. The effects had a variety of expression. Concerning maxillary surgery, some studies showed an initial increase in PBF followed by a decrease to the baseline or even lower levels after 1-3 months. Other studies found an initial decrease in PBF followed by an increase soon after. There were also studies that showed no significant PBF changes, in contrast. Conclusion: Concerning mandibular surgery, a recent study showed a decrease in PBF immediately after sagittal split ramus osteotomy. Some authors detected tooth discoloration of maxillary teeth after Le Fort I osteotomy. Root resorption and root injury were also detected, but were of minor significance. Usually, these adverse effects derive from injury of the vessels of the palatal pedicle. This pedicle should be maintained intact for the avoidance of blood flow impairments. In addition, the descending palatine artery should be protected during maxillary surgery procedures in order to maintain the highest possible blood flow on the maxillary teeth. PMID- 29456772 TI - Multidimensional Analysis of Curved Root Canal Preparation Using Continuous or Reciprocating Nickel-titanium Instruments. AB - Objective: To evaluate transportation (T) and centering ability (CA) of root canal preparations using continuous or reciprocating nickel-titanium endodontic files. Materials and Methods: Ninety-six mesiobuccal root canals of mandibular first and second molars were randomly divided into 6 groups (n=16) according to the rotary file used: 1. ProTaper Next; 2. ProTaper Gold; 3. Mtwo; 4. BioRaCe; 5. WaveOne Gold; 6. Reciproc. Root canals were prepared according to manufacturer's instructions. Cone beam computed tomography scans were obtained before and after root canal preparation. Measurements were made at six different reference points: 2, 3 and 4 mm from the apex and 2, 3 and 4 mm below furcation in different directions. Results: The greatest Mesiodistal (MD) Transportation (T) was found for Reciproc files (p<0.05), and the greatest buccolingual (BL) T, for Reciproc, ProTaper Gold and ProTaper Next files (p<0.05). The greatest Mesiodistal (MD) Centering Ability (CA) was found for BioRaCe files (p<0.05), and the greatest Buccolingual (BL) CA, for BioRaCe and Mtwo files (p<0.05). Conclusion: All systems produced root canal transportation. No file system achieved perfect CA of root preparation. Reciproc files had the greatest MD T and BL T. BioRaCe files had the greatest MD CA, whereas BL CA was similar for BioRaCe and Mtwo files. PMID- 29456773 TI - Molecular Characterization of Multidrug Resistant Uropathogenic E. Coli Isolates from Jordanian Patients. AB - Background: Emergence of multi-drug resistant uropathogenic E. coli strains is an increasing problem to empirical treatment of urinary tract infections in many countries. This study investigated the magnitude of this problem in Jordan. Methods: A total of 262 E. coli isolates were recovered from urine samples of Jordanian patients which were suspected to have urinary tract infections (UTIs). All isolates were primarily identified by routine biochemical tests and tested for antimicrobial susceptibility by disc diffusion method. Fifty representative Multidrug Resistance (MDR) E. coli isolates to 3 or more antibiotic classes were tested for the presence of resistance genes of blaCTX-M- 1, 9 and 15, carbapenemase (blaIMP, blaVIM, blaNDM-1, blaOXA-48), fluoroquinolones mutated genes (parC and gyrA) and clone of ST131 type using PCR methods. Results: A total of 150/262 (57.3%) of E. coli isolates were MDR. Urine samples of hospitalized patients showed significantly more MDR isolates than outpatients. Fifty representative MDR E. coli isolates indicated the following molecular characteristics: All were positive for mutated parC gene and gyrA and for ST131 clone, and 78% were positive for genes of CTX-M-15, 76% for CTX-M-I and for 8% CTX-M-9, respectively. Additionally, all 50 MDR E. coli isolates were negative for carbapenemase genes (blaIMP, blaVIM, blaNDM-1, blaOXA-48), except of one isolate was positive for blaKPC-2 . Conclusion: This study indicates alarming high rates recovery of MDR uropathogenic E. coli from Jordanian patients associated with high rates of positive ST131 clone, fluoroquinolone resistant and important types of blaCTX-M. PMID- 29456774 TI - Gastric Aspiration and Its Role in Airway Inflammation. AB - Gastro-Oesophageal Reflux (GOR) has been associated with chronic airway diseases while the passage of foreign matter into airways and lungs through aspiration has the potential to initiate a wide spectrum of pulmonary disorders. The clinical syndrome resulting from such aspiration will depend both on the quantity and nature of the aspirate as well as the individual host response. Aspiration of gastric fluids may cause damage to airway epithelium, not only because acidity is toxic to bronchial epithelial cells but also due to the effect of digestive enzymes such as pepsin and bile salts. Experimental models have shown that direct instillation of these factors to airways epithelia cause damage with a consequential inflammatory response. The pathophysiology of these responses is gradually being dissected, with better understanding of acute gastric aspiration injury, a major cause of acute lung injury, providing opportunities for therapeutic intervention and potentially, ultimately, improved understanding of the chronic airway response to aspiration. Ultimately, clarification of the inflammatory pathways which are related to micro-aspiration via pepsin and bile acid salts may eventually progress to pharmacological intervention and surgical studies to assess the clinical benefits of such therapies in driving symptom improvement or reducing disease progression. PMID- 29456776 TI - What Percentage of Patients is a Candidate for Unicompartmental Knee Replacement at a Chinese Arthroplasty Center? AB - Background: Data on indication of Unicompartmental Knee Arthroplasty (UKA) in the Asian population are currently not available. The current paper evaluates patients undergoing knee replacement at a Chinese Orthopaedic Specialty Hospital to report the percentage of patients who meet radiographic and clinical indication criteria for UKA. Methods: Over a one-year period 463 consecutive patients (515 knees) underwent primary knee replacement surgery. Clinical data were recorded and preoperative radiographs were assessed. Patients were classified as suitable candidates for UKA based on the degree of deformity, preoperative ROM and radiographic appearance of osteoarthritis. The different indication criteria for body weight and extend of patellofemoral osteoarthritis as reported by Kozinn and Scott as well as the Oxford Group were applied. Results: 160 knees (31%) were excluded because of inflammatory and posttraumatic arthritis. 55 knees had to be excluded because of incomplete radiographs. Of the remaining 300 knees with osteoarthritis, 241 knees were excluded because of extend of deformity (n=156), decreased range of motion (n=119), advanced patellofemoral arthritis with bone loss (n=11) and AP instability (n=1). Of the remaining 63 knees, 54 knees (18%) met the modified Oxford criteria for mobile UKA and only 25 knees (8%) met the Scott and Kozinn criteria for fixed UKA. Conclusion: The current paper suggests that in comparison to Caucasian population, only a smaller percentage of patients at a Chinese Orthopaedic Specialty Hospital meet the indication criteria for UKA. Therefore, it might make sense to concentrate UKA surgeries in high volume centers. PMID- 29456775 TI - Interethnic Variations and Clinical Features of Spondyloarthropathies in a Middle Eastern Country. AB - Objectives: The study aimed to demonstrate the interethnic differences and clinical features of Spondyloarthropathy(SpA) patients in a diverse Middle Eastern Country. Methods: A retrospective review of medical records to collect the required data was conducted for SpA patients at two study institutions in the United Arab Emirates. Results: Of 141 SpA patients found, 88 AS(Ankylosing Spondylitis) patients and 53 'other SpA' patients were identified. Males constituted 81% of AS and 55% of 'other SpA' patients. Patients with AS and 'other SpA' had a mean age of symptom onset of 28 and 34 years, respectively.49% and 40% of AS and 'other SpA' patients had a history of Anti-TNF therapy usage. Enthesitis and Uveitis were noted in 16% and 18% of AS patients whilst 53% and 11% in 'other SpA' patients, respectively.Caucasian, Indian Subcontinent and Arabs constituted 93% of our cohort. Mean age of onset of symptoms in the Indian Subcontinent 'other SpA' group was much greater than the other two ethnicities. Duration of symptoms to diagnosis was 3.5 and 4 years in AS and other SpA patients' respectively. HLA-B27 positivity was found in 53%, 80% and 93% of Arab, Indian Subcontinent and Caucasian AS patients, respectively, whilst seen in 50%, 25% and 33% of the same respective ethnicties in 'other SpA' patients. Conclusion: This study on 141 patients is the largest to analyse inter-ethnic variations in SpA patients in the region. Our cohort shows a short delay in diagnosis with a relatively higher Anti-TNF usage. PMID- 29456777 TI - Toe Gap Force is Related to Ultrasonic Parameter of Calcaneus Bone Status in General Population. AB - Background: Elucidating the relation between bone health condition and muscle strength can provide useful knowledge for Japan's super-aged society. This study ascertained the Speed Of Sound (SOS) of the calcaneus and upper and lower limb muscle strength in a general population. Methods: Medical examinations were conducted of 277 adult residents (100 men, 177 women; average age 67.1 years) of a mountain village. Bilateral hand grip and hand key pinch strength were measured. Hip abductor muscle strength was measured using a hand-held dynamometer. The pressure between the hallux and second toe (toe-gap force) was measured using a toe pressure measuring instrument. The Speed Of Sound (SOS) of the calcaneus was assessed using an ultrasound bone densitometer. Stepwise linear regression was used to identify the predictor of SOS using several factors as explanatory variables: gender, age, height, weight BMI, grip and key pinch power strength, hip abductor muscle strength, and toe-gap force in bilateral side. P values of < .05 were inferred as statistically significant. Results: Significant positive correlation was found between the SOS and each of bilateral hand grip and hand key pinch strength, hip abductor muscle strength, and toe-gap force in all participants. Stepwise logistic regression revealed gender (beta coefficient= -0.32, p= .0001), age (beta coefficient=-0.53, p= .000), height (beta coefficient= -0.19, p= .03), and right toe-gap force (beta coefficient= 0.11, p= .027) as predictors of calcaneal SOS for all participants. Conclusion: Toe-gap force assessment might be more useful to predict calcaneal SOS than grip assessment in the general population. PMID- 29456778 TI - Incidence and Functional Outcomes of Scapholunate Diastases Associated Distal Radius Fractures: A 2-year Follow-Up Scapholunate Dissociation. AB - Background: The Scapholunate Interosseous Ligament (SLIL) is the first intrinsic carpal ligament to be injured in wrist trauma, present in up to 64% of the distal radius fractures. However, it remains unclear what patients develop symptoms, making primary treatment of these injuries accompanying distal radius fractures remains questionable. Objective: The aim of this study was to evaluate the functional outcomes of patients with scapholunate diastasis associated with distal radius fractures. Methods: We evaluated 391 patients with a distal radius fracture. Using Computer Tomography (CT) scans the scapholunate interval was measured. We identified 14 patients with an SLD (>3mm) of the injured wrist, which underwent a CT-scan of the contralateral wrist. To evaluate the functional outcomes at a mean follow up of 136+/-90 weeks, we used the Quick Disabilities of the Arm, Shoulder and Hand (qDASH) Score. Results: There were 8 patients with bilateral SLD and 6 patients with unilateral SLD. Five patients had a qDASH score of 0 and one patient showed a qDASH score of 18.2. The patient with a poor score had bilateral preexisting osteoarthritis of the wrist. No patient had additional surgery of the SLIL. Conclusion: In patients with distal radius fractures, more than half of the 14 patients with an SL gap on CT had widening on the contralateral side. It is therefore worthwhile to image the contralateral wrist before diagnosing a SLD. The patients with unilateral SLD should not be surgically treated at initial presentation because they may have good functional outcomes after a follow up of 2 years. PMID- 29456779 TI - Shared Decision-Making for Nursing Practice: An Integrative Review. AB - Background: Shared decision-making has received national and international interest by providers, educators, researchers, and policy makers. The literature on shared decision-making is extensive, dealing with the individual components of shared decision-making rather than a comprehensive process. This view of shared decision-making leaves healthcare providers to wonder how to integrate shared decision-making into practice. Objective: To understand shared decision-making as a comprehensive process from the perspective of the patient and provider in all healthcare settings. Methods: An integrative review was conducted applying a systematic approach involving a literature search, data evaluation, and data analysis. The search included articles from PubMed, CINAHL, the Cochrane Central Register of Controlled Trials, and PsycINFO from 1970 through 2016. Articles included quantitative experimental and non-experimental designs, qualitative, and theoretical articles about shared decision-making between all healthcare providers and patients in all healthcare settings. Results: Fifty-two papers were included in this integrative review. Three categories emerged from the synthesis: (a) communication/ relationship building; (b) working towards a shared decision; and (c) action for shared decision-making. Each major theme contained sub-themes represented in the proposed visual representation for shared decision-making. Conclusion: A comprehensive understanding of shared decision-making between the nurse and the patient was identified. A visual representation offers a guide that depicts shared decision-making as a process taking place during a healthcare encounter with implications for the continuation of shared decisions over time offering patients an opportunity to return to the nurse for reconsiderations of past shared decisions. PMID- 29456780 TI - Attitudes of Jordanian Adolescent Students Toward Overweight and Obesity. AB - Background: Obesity is a serious public health problem especially among adolescents. Understanding adolescents' attitudes toward obesity and healthy lifestyle is a crucial step to develop effective health programs to treat and prevent obesity. Objectives: To examine the attitudes toward overweight and obesity among Jordanian adolescent students and to identify the components of obesity prevention program that the students perceive as important. Methods: A sample of 1000 students in 8th to 10th grades was randomly selected from 16 schools in Irbid, Jordan. A self-reported questionnaire including attitude related questions was used in a descriptive, cross-sectional study. Results: Generally, the students expressed positive attitudes toward obesity; which means that their attitudes were consistent with societal norms in terms of health and social functioning (mean= 3.5, SD=0.39). Furthermore, the students expressed positive attitudes toward lifestyle; which means that their attitudes were consistent with healthy behaviors (mean=3.7, SD=0.58). However, boys had significantly more positive attitudes than girls (p=0.04). The prevalence of overweight and obesity was 23.8%, while obese and non-obese students had similar attitudes toward lifestyle and obesity. Finally, around 20% to 30% of students desired a prevention program out of school time shared with their families and friends and involves eating healthy food and getting more exercise. Conclusion: More efforts are needed to build effective obesity prevention programs that focus on eating healthy diet and getting more exercise considering gender differences. PMID- 29456781 TI - Functional Magnetic Resonance Imaging of the Domestic Dog: Research, Methodology, and Conceptual Issues. AB - Neuroimaging of the domestic dog is a rapidly expanding research topic in terms of the cognitive domains being investigated. Because dogs have shared both a physical and social world with humans for thousands of years, they provide a unique and socially relevant means of investigating a variety of shared human and canine psychological phenomena. Additionally, their trainability allows for neuroimaging to be carried out noninvasively in an awake and unrestrained state. In this review, a brief overview of functional magnetic resonance imaging (fMRI) is followed by an analysis of recent research with dogs using fMRI. Methodological and conceptual concerns found across multiple studies are raised, and solutions to these issues are suggested. With the research capabilities brought by canine functional imaging, findings may improve our understanding of canine cognitive processes, identify neural correlates of behavioral traits, and provide early-life selection measures for dogs in working roles. PMID- 29456782 TI - Other People's Money: The Role of Reciprocity and Social Uncertainty in Decisions for Others. AB - Many important decisions are taken not by the person who will ultimately gain or lose from the outcome, but on their behalf, by somebody else. We examined economic decision-making about risk and time in situations in which deciders chose for others who also chose for them. We propose that this unique setting, which has not been studied before, elicits perception of reciprocity that prompts a unique bias in preferences. We found that decision-makers are less patient (more discounting), and more risk averse for losses than gains, with other peoples' money, especially when their choices for others are more uncertain. Those results were derived by exploiting a computational modeling framework that has been shown to account for the underlying psychological and neural decision processes. We propose a novel theoretical mechanism-precautionary preferences under social uncertainty, which explains the findings. Implications for future research and alternative models are also discussed. PMID- 29456783 TI - The Role of Stress-Induced O-GlcNAc Protein Modification in the Regulation of Membrane Transport. AB - O-linked N-acetylglucosamine (O-GlcNAc) is a posttranslational modification that is increasingly recognized as a signal transduction mechanism. Unlike other glycans, O-GlcNAc is a highly dynamic and reversible process that involves the addition and removal of a single N-acetylglucosamine molecule to Ser/Thr residues of proteins. UDP-GlcNAc-the direct substrate for O-GlcNAc modification-is controlled by the rate of cellular metabolism, and thus O-GlcNAc is dependent on substrate availability. Serving as a feedback mechanism, O-GlcNAc influences the regulation of insulin signaling and glucose transport. Besides nutrient sensing, O-GlcNAc was also implicated in the regulation of various physiological and pathophysiological processes. Due to improvements of mass spectrometry techniques, more than one thousand proteins were detected to carry the O-GlcNAc moiety; many of them are known to participate in the regulation of metabolites, ions, or protein transport across biological membranes. Recent studies also indicated that O-GlcNAc is involved in stress adaptation; overwhelming evidences suggest that O-GlcNAc levels increase upon stress. O-GlcNAc elevation is generally considered to be beneficial during stress, although the exact nature of its protective effect is not understood. In this review, we summarize the current data regarding the oxidative stress-related changes of O-GlcNAc levels and discuss the implications related to membrane trafficking. PMID- 29456784 TI - Idh2 Deficiency Exacerbates Acrolein-Induced Lung Injury through Mitochondrial Redox Environment Deterioration. AB - Acrolein is known to be involved in acute lung injury and other pulmonary diseases. A number of studies have suggested that acrolein-induced toxic effects are associated with depletion of antioxidants, such as reduced glutathione and protein thiols, and production of reactive oxygen species. Mitochondrial NADP+ dependent isocitrate dehydrogenase (idh2) regulates mitochondrial redox balance and reduces oxidative stress-induced cell injury via generation of NADPH. Therefore, we evaluated the role of idh2 in acrolein-induced lung injury using idh2 short hairpin RNA- (shRNA-) transfected Lewis lung carcinoma (LLC) cells and idh2-deficient (idh2-/- ) mice. Downregulation of idh2 expression increased susceptibility to acrolein via induction of apoptotic cell death due to elevated mitochondrial oxidative stress. Idh2 deficiency also promoted acrolein-induced lung injury in idh2 knockout mice through the disruption of mitochondrial redox status. In addition, acrolein-induced toxicity in idh2 shRNA-transfected LLC cells and in idh2 knockout mice was ameliorated by the antioxidant, N acetylcysteine, through attenuation of oxidative stress resulting from idh2 deficiency. In conclusion, idh2 deficiency leads to mitochondrial redox environment deterioration, which causes acrolein-mediated apoptosis of LLC cells and acrolein-induced lung injury in idh2-/- mice. The present study supports the central role of idh2 deficiency in inducing oxidative stress resulting from acrolein-induced disruption of mitochondrial redox status in the lung. PMID- 29456785 TI - Protein Glutathionylation in the Pathogenesis of Neurodegenerative Diseases. AB - Protein glutathionylation is a redox-mediated posttranslational modification that regulates the function of target proteins by conjugating glutathione with a cysteine thiol group on the target proteins. Protein glutathionylation has several biological functions such as regulation of metabolic pathways, calcium homeostasis, signal transduction, remodeling of cytoskeleton, inflammation, and protein folding. However, the exact role and mechanism of glutathionylation during irreversible oxidative stress has not been completely defined. Irreversible oxidative damage is implicated in a number of neurological disorders. Here, we discuss and highlight the most recent findings and several evidences for the association of glutathionylation with neurodegenerative diseases and the role of glutathionylation of specific proteins in the pathogenesis of neurodegenerative diseases. Understanding the important role of glutathionylation in the pathogenesis of neurodegenerative diseases may provide insights into novel therapeutic interventions. PMID- 29456786 TI - Hederagenin Induces Apoptosis in Cisplatin-Resistant Head and Neck Cancer Cells by Inhibiting the Nrf2-ARE Antioxidant Pathway. AB - Acquired resistance to cisplatin is the most common reason for the failure of cisplatin chemotherapy. Hederagenin, triterpenoids extracted from ivy leaves, exhibits antitumor activity in various types of cancer. However, the therapeutic potential of hederagenin in head and neck cancer (HNC) has remained unclear. Therefore, we examined the effects of hederagenin in cisplatin-resistant HNC cells and characterized its molecular mechanisms of action in this context. We evaluated the effects of hederagenin treatment on cell viability, apoptosis, reactive oxygen species (ROS) production, glutathione levels, mitochondrial membrane potential (DeltaPsim), and protein and mRNA expression in HNC cells. The antitumor effect of hederagenin in mouse tumor xenograft models was also analyzed. Hederagenin selectively induced cell death in both cisplatin-sensitive and cisplatin-resistant HNC cells by promoting changes in DeltaPsim and inducing apoptosis. Hederagenin inhibited the Nrf2-antioxidant response element (ARE) pathway and activated p53 in HNC cells, thereby enhancing ROS production and promoting glutathione depletion. These effects were reversed by the antioxidant trolox. Hederagenin activated intrinsic apoptotic pathways via cleaved PARP, cleaved caspase-3, and Bax. The selective inhibitory effects of hederagenin were confirmed in cisplatin-resistant HNC xenograft models. These data suggest that hederagenin induces cell death in resistant HNC cells via the Nrf2-ARE antioxidant pathway.

AB - This study compared the antioxidant status and major lipophilic antioxidants in patients with ataxia-telangiectasia (AT) and Nijmegen breakage syndrome (NBS). Total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), and concentrations of coenzyme Q10 (CoQ10) and vitamins A and E were estimated in the plasma of 22 patients with AT, 12 children with NBS, and the healthy controls. In AT patients, TAS (median 261.7 MUmol/L) was statistically lower but TOS (496.8 MUmol/L) was significantly elevated in comparison with the healthy group (312.7 MUmol/L and 311.2 MUmol/L, resp.). Tocopherol (0.8 MUg/mL) and CoQ10 (0.1 MUg/mL) were reduced in AT patients versus control (1.4 MUg/mL and 0.3 MUg/mL, resp.). NBS patients also displayed statistically lower TAS levels (290.3 MUmol/L), while TOS (404.8 MUmol/L) was comparable to the controls. We found that in NBS patients retinol concentration (0.1 MUg/mL) was highly elevated and CoQ10 (0.1 MUg/mL) was significantly lower in comparison with those in the healthy group. Our study confirms disturbances in redox homeostasis in AT and NBS patients and indicates a need for diagnosing oxidative stress in those cases as a potential disease biomarker. Decreased CoQ10 concentration found in NBS and AT indicates a need for possible supplementation. PMID- 29456789 TI - Novel Modifications of Glycopeptide Antibiotics via Total Synthesis. AB - Although vancomycin has been in clinical use since the late 1950s, resistance due to alteration in the target microbe's peptidoglycan can vary significantly, reducing its activity. Total synthesis of derivatives has now led to a molecule with very significant activity against resistant strains. PMID- 29456788 TI - Antroquinonol Exerts Immunosuppressive Effect on CD8+ T Cell Proliferation and Activation to Resist Depigmentation Induced by H2O2. AB - Antroquinonol was investigated as antioxidant and inhibition of inflammatory responses. Our study was to evaluate its immunosuppressive effect on CD8+ T cells and protective effect on depigmentation. CD8+ T cells were treated with antroquinonol in vitro, and C57BL/6 mice were treated with antroquinonol with or without H2O2in vivo for 50 consecutive days. We found antroquinonol could inhibit proliferation of CD8+ T cells and suppress the production of cytokines IL-2 and IFN-gamma and T cell activation markers CD69 and CD137 in vitro. H2O2 treatment induced depigmentation and reduced hair follicle length, skin thickness, and tyrosinase expression in vivo. Whereas, antroquinonol obviously ameliorated depigmentation of mice skin and resisted the reduction of hair follicle length, skin thickness, and tyrosinase expression induced by H2O2. Antroquinonol decreased CD8+ T cell infiltration in mice skin, inhibited the production of IL-2 and IFN-gamma, and decreased the expression of CXCL10 and CXCR3. Summarily, our data shows antroquinonol inhibits CD8+ T cell proliferation in vitro. It also reduces CD8+ T cell infiltration and proinflammatory cytokine secretion and suppresses the thinning of epidermal layer in vivo. Our findings suggest that antroquinonol exerts immunosuppressive effects on CD8+ T cell proliferation and activation to resist depigmentation induced by H2O2. PMID- 29456790 TI - Late-Stage Microsomal Oxidation Reduces Drug-Drug Interaction and Identifies Phosphodiesterase 2A Inhibitor PF-06815189. AB - Late-stage oxidation using liver microsomes was applied to phosphodiesterase 2 inhibitor 1 to reduce its clearance by cytochrome P450 enzymes, introduce renal clearance, and minimize the risk for victim drug-drug interactions. This approach yielded PF-06815189 (2) with improved physicochemical properties and a mixed metabolic profile. This example highlights the importance of C-H diversification methods to drug discovery. PMID- 29456791 TI - Nonacidic Chemotype Possessing N-Acylated Piperidine Moiety as Potent Farnesoid X Receptor (FXR) Antagonists. AB - Farnesoid X receptor (FXR) plays a major role in the control of cholesterol metabolism. Antagonizing transcriptional activity of FXR is an effective means to treat the relevant metabolic syndrome. Some of antagonists so far have the charged functions; however, they may negatively affect the pharmacokinetics. We describe herein a structure-activity relationship (SAR) exploration of nonacidic FXR antagonist 6 focusing on two regions in the structure and biological evaluation of nonacidic 10 with the characteristic N-acylated piperidine group obtained from SAR studies. As the robust affinity to FXR is feasible with our nonacidic analogue, 10 is among the most promising candidates for in vivo testing. PMID- 29456792 TI - N-Leucinyl Benzenesulfonamides as Structurally Simplified Leucyl-tRNA Synthetase Inhibitors. AB - N-Leucinyl benzenesulfonamides have been discovered as a novel class of potent inhibitors of E. coli leucyl-tRNA synthetase. The binding of inhibitors to the enzyme was measured by using isothermal titration calorimetry. This provided information on enthalpy and entropy contributions to binding, which, together with docking studies, were used for structure-activity relationship analysis. Enzymatic assays revealed that N-leucinyl benzenesulfonamides display remarkable selectivity for E. coli leucyl-tRNA synthetase compared to S. aureus and human orthologues. The simplest analogue of the series, N-leucinyl benzenesulfonamide (R = H), showed the highest affinity against E. coli leucyl-tRNA synthetase and also exhibited antibacterial activity against Gram-negative pathogens (the best MIC = 8 MUg/mL, E. coli ATCC 25922), which renders it as a promising template for antibacterial drug discovery. PMID- 29456793 TI - Synthesis of Novel Tetrahydroisoquinoline CXCR4 Antagonists with Rigidified Side Chains. AB - A structure-activity relationship study of potent TIQ15-derived CXCR4 antagonists is reported. In this investigation, the TIQ15 side-chain was constrained to improve its drug properties. The cyclohexylamino congener 15a was found to be a potent CXCR4 inhibitor (IC50 = 33 nM in CXCL12-mediated Ca2+ flux) with enhanced stability in liver microsomes and reduced inhibition of CYP450 (2D6). The improved CXCR4 antagonist 15a has potential therapeutic application as a single agent or combinatory anticancer therapy. PMID- 29456794 TI - Discovery of 3,3'-Spiro[Azetidine]-2-oxo-indoline Derivatives as Fusion Inhibitors for Treatment of RSV Infection. AB - A new series of 3,3'-spirocyclic-2-oxo-indoline derivatives was synthesized and evaluated against respiratory syncytial virus (RSV) in a cell-based assay and animal model. Extensive structure-activity relationship study led to a lead compound 14h, which exhibited excellent in vitro potency with an EC50 value of 0.8 nM and demonstrated 71% oral bioavailability in mice. In a mouse challenge model of RVS infection, 14h demonstrated superior efficacy with a 3.9log RSV virus load reduction in the lung following an oral dose of 50 mg/kg. PMID- 29456795 TI - Discovery of EBI-2511: A Highly Potent and Orally Active EZH2 Inhibitor for the Treatment of Non-Hodgkin's Lymphoma. AB - A novel series of benzofuran derived EZH2 inhibitors were discovered through a scaffold hopping approach based on the clinical compound of EPZ-6438. Further rational structure-activity relationship exploration and optimization led to the discovery of more potent EZH2 inhibitors with oral bioavailability in mice and rats. A lead compound EBI-2511 (compound 34) demonstrated excellent in vivo efficacy in Pfeiffer tumor Xenograft models in mouse and is under preclinical development for the treatment of cancers associated with EZH2 mutations. PMID- 29456796 TI - Discovery of Tetralones as Potent and Selective Inhibitors of Acyl CoA:Diacylglycerol Acyltransferase 1. AB - Acyl-CoA:diacylglycerol acyltransferase 1 (DGAT1) plays an important role in triglyceride synthesis and is a target of interest for the treatment of metabolic disorders. Herein we describe the structure-activity relationship of a novel tetralone series of DGAT1 inhibitors and our strategies for overcoming genotoxic liability of the anilines embedded in the chemical structures, leading to the discovery of a candidate compound, (S)-2-(6-(5-(3-(3,4 difluorophenyl)ureido)pyrazin-2-yl)-1-oxo-2-(2,2,2-trifluoroethyl)-1,2,3,4 tetrahydronaphthalen-2-yl)acetic acid (GSK2973980A, 26d). Compound 26d is a potent and selective DGAT1 inhibitor with excellent DMPK profiles and in vivo efficacy in a postprandial lipid excursion model in mice. Based on the overall biological and developability profiles and acceptable safety profiles in the 7 day toxicity studies in rats and dogs, compound 26d was selected as a candidate compound for further development in the treatment of metabolic disorders. PMID- 29456797 TI - Using tert-Butyl Groups in a Ligand To Identify Its Binding Site on a Protein. AB - Few methods allow determining the binding site of tightly binding ligands. We show that ligands containing a tert-butyl (e.g., Boc) group produce easily observable nuclear Overhauser effects (NOE) with the target protein even when the tert-butyl group is not highly solvent exposed. NOEs with methyl groups of the target protein are readily assigned by selectively isotope labeling, presenting a practical and quick way to pinpoint the location of the ligand without any prior specific nuclear magnetic resonance assignments of the protein. The approach works for nonexchanging ligands as well as for weakly binding ligands. PMID- 29456798 TI - 18F-Radiolabeled Panobinostat Allows for Positron Emission Tomography Guided Delivery of a Histone Deacetylase Inhibitor. AB - Histone deacetylase (HDAC) inhibition is becoming an increasingly popular approach to treat cancer, as HDAC overexpression is common in many malignancies. The blood-brain barrier (BBB) prevents systemically delivered drugs from reaching brain at effective concentration, making small-molecule-HDAC inhibition in brain tumors particularly challenging. To circumvent the BBB, novel routes for administering therapeutics are being considered in the clinic, and a need exists for drugs whose deliveries can be directly imaged, so that effective delivery across the BBB can be monitored. We report chemistry for radiolabeling the HDAC inhibitor, panobinostat, with fluoride-18 (compound-1). Like panobinostat, compound 1 retains nanomolar efficacy in diffuse intrinsic pontine glioma (DIPG IV and XIII) cells (IC50 = 122 and 108 nM, respectively), with lesser activity against U87 glioma. With a favorable therapeutic ratio, 1 is highly selective to glioma and demonstrates considerably less toxicity toward healthy astrocyte controls (IC50 = 5265 nM). Compound 1 is stable in aqueous solution at physiological pH (>7 days, fetal bovine serum), and its delivery can be imaged by positron emission tomography (PET). Compound 1 is synthesized in two steps, and employs rapid, late-stage aqueous isotopic exchange 18F-radiochemistry. PET is used to image the in vivo delivery of [18F]-1 to the murine central nervous system via convection enhanced delivery. PMID- 29456799 TI - From RORgammat Agonist to Two Types of RORgammat Inverse Agonists. AB - Biaryl amides as new RORgammat modulators were discovered. The crystal structure of biaryl amide agonist 6 in complex with RORgammat ligand binding domain (LBD) was resolved, and both "short" and "long" inverse agonists were obtained by removing from 6 or adding to 6 a proper structural moiety. While "short" inverse agonist (8) recruits a corepressor peptide and dispels a coactivator peptide, "long" inverse agonist (9) dispels both. The two types of inverse agonists can be utilized as potential tools to study mechanisms of Th17 transcriptional network inhibition and related disease biology. PMID- 29456800 TI - Discovery and in Vitro Optimization of 3-Sulfamoylbenzamides as ROMK Inhibitors. AB - Inhibitors of the renal outer medullary potassium channel (ROMK) show promise as novel mechanism diuretics, with potentially lower risk of diuretic-induced hypokalemia relative to current thiazide and loop diuretics. Here, we report the identification of a novel series of 3-sulfamoylbenzamide ROMK inhibitors. Starting from HTS hit 4, this series was optimized to provide ROMK inhibitors with good in vitro potencies and well-balanced ADME profiles. In contrast to previously reported small-molecule ROMK inhibitors, members of this series were demonstrated to be highly selective for inhibition of human over rat ROMK and to be insensitive to the N171D pore mutation that abolishes inhibitory activity of previously reported ROMK inhibitors. PMID- 29456801 TI - Identification of Potent Indoleamine 2,3-Dioxygenase 1 (IDO1) Inhibitors Based on a Phenylimidazole Scaffold. AB - Inhibition of indoleamine 2,3-dioxygenase (IDO1) is an attractive immunotherapeutic approach for the treatment of a variety of cancers. Dysregulation of this enzyme has also been implicated in other disorders including Alzheimer's disease and arthritis. Herein, we report the structure based design of two related series of molecules: N1-substituted 5 indoleimidazoles and N1-substituted 5-phenylimidazoles. The latter (and more potent) series was accessed through an unexpected rearrangement of an imine intermediate during a Van Leusen imidazole synthesis reaction. Evidence for the binding modes for both inhibitor series is supported by computational and structure-activity relationship studies. PMID- 29456802 TI - HTS by NMR for the Identification of Potent and Selective Inhibitors of Metalloenzymes. AB - We have recently proposed a novel drug discovery approach based on biophysical screening of focused positional scanning libraries in which each element of the library contained a common binding moiety for the given target or class of targets. In this Letter, we report on the implementation of this approach to target metal containing proteins. In our implementation, we first derived a focused positional scanning combinatorial library of peptide mimetics (of approximately 100,000 compounds) in which each element of the library contained the metal-chelating moiety hydroxamic acid at the C-terminal. Screening of this library by nuclear magnetic resonance spectroscopy in solution allowed the identification of a novel and selective compound series targeting MMP-12. The data supported that our general approach, perhaps applied using other metal chelating agents or other initial binding fragments, may result very effective in deriving novel and selective agents against metalloenzyme. PMID- 29456803 TI - Potent Inhibitors of Hepatitis C Virus NS3 Protease: Employment of a Difluoromethyl Group as a Hydrogen-Bond Donor. AB - The design and synthesis of potent, tripeptidic acylsulfonamide inhibitors of HCV NS3 protease that contain a difluoromethyl cyclopropyl amino acid at P1 are described. A cocrystal structure of 18 with a NS3/4A protease complex suggests the presence of a H-bond between the polarized C-H of the CHF2 moiety and the backbone carbonyl of Leu135 of the enzyme. Structure-activity relationship studies indicate that this H-bond enhances enzyme inhibitory potency by 13- and 17-fold compared to the CH3 and CF3 analogues, respectively, providing insight into the deployment of this unique amino acid. PMID- 29456804 TI - Biocompatible Boron-Containing Prodrugs of Belinostat for the Potential Treatment of Solid Tumors. AB - Despite promising therapeutic utilities for treatment of hematological malignancies, histone deacetylase inhibitor (HDACi) drugs have not proven as effective in the treatment of solid tumors. To expand the clinical indications of HDACi drugs, we developed novel boron-containing prodrugs of belinostat (2), one of which efficiently releases active 2 through a cascade of reactions in cell culture and demonstrates activities comparable to 2 against a panel of cancer cell lines. Importantly, prodrug 7 is more efficacious than belinostat in vivo, not only inhibiting the growth of tumor but also reducing tumor volumes in an MCF 7 xenograft tumor model owing to its superior biocompatibility, which suggests its clinical potential in the treatment of solid tumors. PMID- 29456805 TI - Click-Addressable Cassette for Photoaffinity Labeling. AB - A small molecule 1 was designed to contain an alkyne, a trifluoromethyl phenyldiazirine, and a free piperidine-NH for facile conjugation to protein binding ligands. This "cassette" 1 was synthesized via a relatively direct route involving only routine steps. In this proof-of-concept study, putative ligands for carbonic anhydrase IX and for TrkC were conjugated to 1. Photoaffinity labeling was performed using purified extracellular regions of both these protein receptors, and using cells that express these receptors (isolation via a pull down procedure), labeling of the protein was observed in all four experiments. PMID- 29456806 TI - Women with hereditary breast cancer predispositions should avoid using their smartphones, tablets, and laptops at night. AB - Breast cancer is the most common malignancy among women, both in the developed and developing countries. Women with mutations in the BRCA1 and BRCA2 genes have an increased risk of breast and ovarian cancers. Recent studies show that short wavelength visible light disturb the secretion of melatonin and causes circadian rhythm disruption. We have previously studied the health effects of exposure to different levels of radiofrequency electromagnetic fields (RF-EMFs) such as mobile phones, mobile base stations, mobile phone jammers, laptop computers, and radars. Moreover, over the past several years, we investigated the health effects of exposure to the short wavelength visible light in the blue region emitted from digital screens. The reduction of melatonin secretion after exposure to blue light emitted from smartphone's screen has been reported to be associated with the negative impact of smartphone use at night on sleep. We have shown that both the blue light and RF-EMFs generated by mobile phones are linked to the disruption of the circadian rhythm in people who use their phones at night. Therefore, if women with hereditary breast cancer predispositions use their smartphones, tablets and laptops at night, disrupted circadian rhythms (suppression of melatonin caused by exposure to blue light emitted from the digital screens), amplifies the risk of breast cancer. It can be concluded that women who carry mutated BRCA1 or BRCA2, or women with family history of breast cancer should avoid using their smartphones, tablets and laptops at night. Using sunglasses with amber lenses, or smartphone applications which decrease the users' exposure to blue light before sleep, at least to some extent, can decrease the risk of circadian rhythm disruption and breast cancer. PMID- 29456807 TI - Potential of polymeric particles as future vaccine delivery systems/adjuvants for parenteral and non-parenteral immunization against tuberculosis: A systematic review. AB - Objectives: Production of effective tuberculosis (TB) vaccine is necessity. However, the development of new subunit vaccines is faced with concerns about their weak immunogenicity. To overcome such problems, polymers-based vaccine delivery systems have been proposed to be used via various routes. The purpose of this study was to determine the potential of polymeric particles as future vaccine delivery systems/adjuvants for parenteral and non-parenteral immunization against TB. Materials and Methods: PubMed, Scopus, Science-Direct, and the ISI web of knowledge databases were searched for related keywords. A total of 420 articles, written up to June 25, 2016, were collected on the potential of polymeric particles as TB vaccine delivery systems after parenteral and non parenteral immunization. Thirty-one relevant articles were selected by applying inclusion and exclusion criteria. Results: It was shown that the immunogenicity of TB vaccines had been improved by using biodegradable and non-biodegradable synthetic polymers as well as natural polymers and they are better able to enhance the humoral and cellular immune responses, compared to TB vaccines alone. The present study revealed that various polymeric particles, after M. tuberculosis challenge in animal models, provide long-lasting protection against TB. PLGA (poly (lactide-co-glycolide)) and chitosan polymers were widely used as TB vaccine delivery systems/adjuvants. Conclusion: It seems that PLGA and chitosan polymers are well-suited particles for the parenteral and non-parenteral administration of TB vaccines, respectively. Non-biodegradable synthetic polymers in comparison with biodegradable synthetic and natural polymers have been used less frequently. Therefore, further study on this category of polymers is required. PMID- 29456808 TI - Administration of melatonin protects against acetylsalicylic acid-induced impairment of male reproductive function in mice. AB - Objectives: Melatonin, an important hormone secreted by the epiphysis, is a powerful anti-oxidant with a high potential to neutralize medical toxins. The goal of this study was to demonstrate the beneficial effect of melatonin on epididymal sperm and reproductive parameters in mice treated with acetylsalicylic acid (ASA). Materials and Methods: Male adult mice were divided into four treatment groups: control, ASA, melatonin, and ASA+melatonin. Mice were administered ASA (50 mg/kg, orally) and/or melatonin (10 mg/kg, intraperitoneally), or vehicle control, for 14 days. Sperm count, sperm motility, and sperm morphology were evaluated to assess fertility. A colorimetric assay was used to measure serum total antioxidant capacity (TAC). A sperm chromatin dispersion (SCD) test was used to assess sperm chromatin integrity. Sex hormone levels were measured by ELISA. Results: Compared to the control group, ASA treatment resulted in a significant decrease in sperm parameters (P<0.05), as well as a decrease in the integrity of sperm chromatin (P<0.01). ASA treatment also reduced serum testosterone and TAC levels (P<0.05). Co-administration of melatonin with ASA significantly improved epididymal sperm parameters and increased serum testosterone and TAC levels compared to the ASA-treated group. LH level was not different in the combined treatment group compared to control or ASA treatment. Conclusion: Short-term administration of ASA (50 mg/kg) has adverse effects on male reproductive function in mice. Co-administration of melatonin protects against ASA-induced impairment of male reproductive function by preventing the reduction in serum TAC and testosterone levels seen with ASA treatment alone. PMID- 29456809 TI - Hypericin-photodynamic therapy inhibits proliferation and induces apoptosis in human rheumatoid arthritis fibroblast-like synoviocytes cell line MH7A. AB - Objectives: To elucidate the effects and potential mechanisms of hypericin photodynamic therapy (HYP-PDT) for treating the human rheumatoid arthritis (RA) fibroblast-like synoviocyte (FLS) MH7A cell-line. Materials and Methods: MH7A cells were subjected to HYP-PDT intervention and apoptosis was evaluated via MTT, nuclear staining, and flowcytometry analyses. Intracellular reactive oxygen species (ROS) were measured with the fluorescent probe 2'7'-dichlorofluorescein diacetate (DCFH-DA). To verify the effects of HYP on apoptotic and nuclear factor kappa-B (NF-kappaB) pathways, caspase-8, 9, poly-ADP-ribose polymerase (PARP), phosphorylated (p)-NF-kappaB p65, NF-kappaB p65 and p-IkappaBalpha protein expressions were quantified with Western blot. Quantitative real-time PCR was used to assay NF-kappaB p65 mRNA. Results: HYP-PDT inhibited MH7A cell viability and induced apoptosis in a dose-dependent manner. Meanwhile, intracellular ROS levels increased significantly after HYP-PDT treatment. Furthermore, the expression of cleaved caspase-9 and PARP was increased by HYP-PDT treatment, with a concurrent decline in NF-kappaB. Conclusion: HYP-PDT induces apoptosis in MH7A cells, at least partially, via generation of ROS, regulation of the apoptotic pathway and suppression of the NF-kappaB pathway. These findings suggest that HYP PDT may be a potential treatment for RA. PMID- 29456810 TI - Minocycline through attenuation of oxidative stress and inflammatory response reduces the neuropathic pain in a rat model of chronic constriction injury. AB - Objectives: Several lines of evidence showed that minocycline possesses antioxidant and anti-inflammatory properties. This study aimed to demonstrate the effects of minocycline in rats subjected to chronic constriction injury (CCI). Materials and Methods: In this study four groups (n = 6-8) of rats were used as follows: Sham, CCI, CCI + minocycline (MIN) 10 mg/Kg (IP) and CCI + MIN 30 mg/Kg (IP). On days 3, 7, 14, and 21 post-surgery hot-plate, acetone, and von Frey tests were carried out. Finally, Motor Nerve Conduction Velocity Evaluation (MNCV) assessment was performed and spinal cords were harvested in order to measure tissue concentrations of TNF_alpha, IL-1beta, Glutathione peroxidase (GPx), Superoxide dismutase (SOD) and Malondialdehyde (MDA). Extent of perineural inflammation and damage around the sciatic nerve was histopathologically evaluated. Results: Our results demonstrated that CCI significantly caused hyperalgesia and allodynia twenty-one days after CCI. MIN attenuated heat hyperalgesia, cold and mechanical allodynia and MNCV in animals. MIN also decreased the levels of TNF_alpha and IL-1beta. Antioxidative enzymes (SOD, MDA, and GPx) were restored following MIN treatment. Our findings showed that MIN decreased perineural inflammation around the sciatic nerve. According to the results, the neuropathic pain reduced in the CCI hyperalgesia model using 30 mg/kg of minocycline. Conclusion: It is suggested that antinociceptive effects of minocycline might be mediated through the inhibition of inflammatory response and attenuation of oxidative stress. PMID- 29456811 TI - In vivo activity assessment of some Tanacetum species used as traditional wound healer along with identification of the phytochemical profile by a new validated HPLC method. AB - Objectives: Tanacetum species are traditionally used as insecticide, and externally wound healer as well as for anti-inflammatory and antihistaminic properties. The in vivo wound-healing and anti-inflammatory potential of four Tanacetum species, Tanacetum argenteum (Lam.) Willd. subsp. argenteum (TA), Tanacetum heterotomum (Bornm.) Grierson (TH), Tanacetum densum (Lab.) Schultz Bip. subsp. sivasicum (TD), and Tanacetum vulgare L. (TV) was investigated. Materials and Methods: The chloroform (CHCl3) and methanol:water (80:20) extracts were prepared from the aerial parts of each plant. For assessment of the wound healing activity, linear incision on rats and circular excision on mice wound models were used and histopathological analyses were conducted on the tissues treated with the test materials. For the evaluation of the anti-inflammatory activity, Whittle Method based on the inhibition of the acetic acid-induced increase in capillary permeability was used. In order to elucidate the phytochemical contents of the extracts, HPLC profiles of active fractions were screened and quantitative analysis was conducted within the scope of HPLC analysis. Results: The CHCl3 extracts of TD, TA and TV were found to have significant wound healing activity (37.1%, 30.8% and 26.1% tensile strength; 88.05%, 72.93% and 44.88% contraction values, respectively) and anti-inflammatory activities (31.5% and 26.6% inhibition values for TD and TA). Parthenolide content of the CHCl3 extracts of TA, TH and TV were found 242.66+/-1.53, 190.16+/ 5.62 and 177.51+/-3.73 ug/100 mg plant material, respectively. Conclusion: According to the results, the other secondary metabolites present in the aerial parts of the Tanacetum species possibly exerted synergistic effects on the observed healing of the wounds. PMID- 29456812 TI - Preparation and evaluation of PCL-PEG-PCL micelles as potential nanocarriers for ocular delivery of dexamethasone. AB - Objectives: Micelles have been studied as nanoparticulate drug delivery systems for improving the topical ocular delivery of hydrophobic drugs. The objective of this study was to develop and characterize dexamethasone-loaded polycaprolactone polyethylene glycol-polycaprolactone (PCL-PEG-PCL) micelles to improve patient compliance and enhance the ocular bioavailability of poorly water-soluble drugs. Materials and Methods: The PCL-PEG-PCL copolymers were synthesized via the ring opening polymerization of epsilon-caprolactone in the presence of PEG. The resulting purified copolymers were characterized by GPC, NMR, FTIR, XRD and DSC. The critical micelle concentrations (CMCs) of the mentioned copolymers were determined. Dexamethasone was loaded into polymeric micelles by film hydration method, and dexamethasone-loaded micelles were characterized by TEM and DLS. Drug release kinetics and ex vivo corneal permeability were also determined. Results: The CMC of the synthetized copolymers was approximately 0.03 mg/ml. Aqueous solutions of the resulting copolymers (400 mg/ml) rapidly formed a gel in situ at 34 degrees C. The TEM results exhibited the successful formation of spherical micelles. The size of the prepared micelles was approximately 40 nm. Formulated micelles sustained the release of the incorporated dexamethasone for 5 days. Conclusion: Data from ex vivo permeability tests indicated that PCL-PEG-PCL micelles can be suitable candidates for the ocular delivery of dexamethasone and, likely, other hydrophobic drugs. PMID- 29456813 TI - Evaluation of TNF-alpha and IL-6 mRNAs expressions in visceral and subcutaneous adipose tissues of polycystic ovarian rats and effects of resveratrol. AB - Objectives: Some studies suggest that chronic low-grade inflammation is involved in insulin resistance in polycystic ovary syndrome (PCOS). This study assessed possible involvement of alteration in expression of two pro-inflammatory factors, tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) in adipose tissues of PCOS rats in the impairment of insulin actions. Also, effects of resveratrol as an anti-inflammatory agent were investigated. Materials and Methods: Fifteen female Wistar rats (21 days old) were divided into three groups (n=5): I) Control, II) PCO-model-saline: served as PCOS rats and to induce PCOS, received subcutaneously testosterone enanthate 1 mg/100 g body weight subcutaneously for 35 days, III) PCO-model-resveratrol, after receiving testosterone, received resveratrol 10 mg/kg intraperitoneally for 28 days. The expression of Tnf-alpha and Il-6 mRNAs in adipose tissues was determined by the qRT-PCR method. Results: The Il-6 mRNA expression in the visceral adipose tissue of PCOS rats was increased in comparison to controls (P<0.05). Tnf-alpha and Il-6 mRNA expression in visceral and subcutaneous adipose tissues of polycystic ovarian rats was similar to controls. The expression of Tnf-alpha mRNA in subcutaneous adipose tissue and Tnf-alpha and Il-6 mRNAs in the visceral adipose tissue of the PCO-model-resveratrol group were lower than PCOS rats (P<0.05). Conclusion: Increased expression of Il-6 mRNA in the visceral adipose tissue of polycystic ovarian rats may be one cause of insulin resistance observed in them and resveratrol as an anti-inflammatory and anti-hyperglycemic agent may decrease the risk of diabetes by reduction of expression of pro-inflammatory cytokines TNF alpha and IL-6 in PCOS patients. PMID- 29456814 TI - Ascorbic acid augments colony spreading by reducing biofilm formation of methicillin-resistant Staphylococcus aureus. AB - Objectives: Staphylococcus aureus is a Gram-positive pathogen, well known for its resistance and versatile lifestyle. Under unfavourable conditions, it adapts biofilm mode of growth. For staphylococcal biofilm formation, production of extracellular polymeric substances (EPS) is a pre-requisite, which is regulated by ica operon-encoded enzymes. This study was designed to know the impact of ascorbic acid on biofilm formation and colony spreading processes of S. aureus and MRSA. Materials and Methods: The isolates of methicillin-resistant S. aureus (MRSA) used in present study, were recovered from different food samples. Various selective and differential media were used for identification and confirmation of S. aureus. Agar dilution method was used for determination of oxacillin and ascorbic acid resistance level. MRSA isolates were re-confirmed by E-test and by amplification of mecA gene. Tube methods and Congo-Red agar were used to study biofilm formation processes. Gene expression studies were carried on real-time reverse transcriptase-polymerase chain reaction (RT-PCR). Results: The results revealed the presence of mecA gene belonging to SCCmecA type IV along with agr type II in the isolates. In vitro studies showed the sub-inhibitory concentration of oxacillin induced biofilm production. However, addition of sub-inhibitory dose of ascorbic acid was found to inhibit EPS production, biofilm formation and augment colony spreading on soft agar plates. The inhibition of biofilm formation and augmentation of colony spreading observed with ascorbic acid alone or in combination with oxacillin. Moreover, gene expression studies showed that ascorbic acid increases agr expression and decreases icaA gene expression. Conclusion: The present study concluded that ascorbic acid inhibits biofilm formation, promotes colony spreading and increases agr gene expression in MRSA. PMID- 29456815 TI - CRISPR/Cas9, a new approach to successful knockdown of ABCB1/P-glycoprotein and reversal of chemosensitivity in human epithelial ovarian cancer cell line. AB - Objectives: Multidrug resistance (MDR) is a major obstacle in the successful chemotherapy of ovarian cancer. Inhibition of P-glycoprotein (P-gp), a member of ATP-binding cassette (ABC) transporters, is a well-known strategy to overcome MDR in cancer. The aim of this study was to investigate the efficiency and ability of CRISPR/Cas9 genome editing technology to knockdown ABCB1 gene expression in adriamycin resistant (A2780/ADR) ovarian cancer cell line and evaluate the sensitivity changes to doxorubicin. Materials and Methods: Three single-guide RNAs (sgRNAs) targeting the fourth and fifth exons of human ABCB1 gene were designed in this study. Expression level of ABCB1 was detected using quantitative real time PCR (qRT-PCR) after co-transfection of all three sgRNAs into A2780/ADR cell line and subsequent antibiotic selection. Drug sensitivity to doxorubicin was determined by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Results: The results showed that CRISPR/Cas9 system could significantly reduce the expression of P-gp. The dramatic decline in ABCB1 gene expression was associated with increased sensitivity of cells transfected with sgRNAs to doxorubicin. Conclusion: Based on the results of this study, it is concluded that the CRISPR-based systems, used in the present study, effectively down-regulated the target gene and acted as an ideal and cost-effective tool for gene editing of A2780/ADR cell line resulting in restoration of nonmalignant phenotype. PMID- 29456816 TI - Anti-inflammatory activity and chemical composition of Pycnocycla bashagardiana fruit's essential oil in animal models. AB - Objectives: Pycnocycla bashagardiana is an endemic species found only in Iran. Due to the presence of myristicin as the major component of the fruit's oil we were prompted to assess the antinociceptive and anti-inflammatory properties of P. bashagardiana fruit's essential oil (PBFEO). Materials and Methods: The analgesic activities of PBFEO (100, 200, and 400 mg/kg, IP) were studied by hot plate and formalin tests in mice. Control and standard groups received vehicle and morphine (5 mg/kg, IP), respectively. The acute anti-inflammatory effect of PBFEO (200 and 400 mg/kg, IP) were assessed by carrageenan-induced paw edema method in 30 min, 1, 2, 3, and 4 hr after carrageenan injection and the chronic anti-inflammatory effect of PBFEO (50 and 100 mg/kg, IP) were assessed by the cotton pellet-induced granuloma method in rats. Results: In hot-plate and formalin tests, the studied doses of PBFEO were not effective. However, in carrageenan test, all studied doses of PBFEO significantly reduced the paw edema in comparison to the control animals (P<0.05). Anti-inflammatory activity of PBFEO (200 and 400 mg/kg, P<0.05) was found to be more than mefenamic acid (30 mg/kg). In cotton pellet-induced granuloma, PBFEO was also effective regarding the transudate and granuloma formation amount. PBFEO was analyzed by gas chromatography-mass spectrometry and 12 constituents, representing 96.0% of the oil, were identified. The major component of the oil was characterized as myristicin which might be responsible for the anti-inflammatory activity. Conclusion: The results suggest that PBFEO possesses biologically active constituents that have significant peripheral anti-inflammatory effects.

AB - Objectives: This study aims to investigate the pathogenicity and possible mechanisms of S100A9 function in mice models of scleroderma. Materials and Methods: The content of S100A9 in the skin tissues of mice with scleroderma was determined. Different concentrations of bleomycin (BLM) and S100A9 were subcutaneously injected into the backs of mice simultaneously, and then pathological changes in the skin of these mice were monitored. Specifically, the levels of inflammatory cytokines and alpha smooth muscle actin (alpha-SMA), the activation of extracellular regulated kinase 1/2 (ERK1/2), mitogen-activated protein kinase (MAPK) and nuclear factor-kappa B (NF-kappaB) pathways, and the expression of the receptor for advanced glycation end-product (RAGE) in the skin were determined. Results: The content of S100A9 in the skin tissues of mice with scleroderma was determined. Different concentrations of BLM and S100A9 were subcutaneously injected into the backs of mice simultaneously, and then pathological changes in the skin of these mice were monitored. Specifically, the levels of inflammatory cytokines and alpha smooth muscle actin (alpha-SMA), the activation of extracellular regulated kinase 1/2 (ERK1/2) mitogen-activated protein kinase (MAPK) and nuclear factor-kappa B (NF-kappaB) pathways, and the expression of the receptor for advanced glycation end-product (RAGE) in the skin were determined. Conclusion: S100A9 aggravates dermal fibrosis in BLM-induced scleroderma (BIS) mice, and its mechanisms might be mediated by RAGE, ERK1/2, and NF-kappaB pathway. PMID- 29456818 TI - Synthesis and antiplasmodial activity of novel phenanthroline derivatives: An in vivo study. AB - Objectives: Due to the rapid increased drug resistance to Plasmodium parasites, an urgent need to achieve new antiplasmodial drugs is felt. Therefore, in this study, the new synthetic phenanthroline derivatives were synthesized with antiplasmodial activity. Materials and Methods: A series of 1,10-phenanthroline derivatives containing amino-alcohol and amino-ether substituents were synthesized via facile procedures, starting with 5,6-epoxy-1,10-phenanthroline. Their antiplasmodial activity was then evaluated using Peter's 4-day suppressive test against Plasmodium berghei-infected mice (ANKA strain). Furthermore, the mean survival time of the mice treated with synthetic compounds was compared with the negative control group. Results: The results demonstrated that the compounds 6-(3-(dibutylamino)propylamino)-5,6-dihydro-1,10-phenanthroline-5-ol(7b) at the dose of 150 mg/kg/day and 4-(1,10-phenanthroline-5-yloxy)-N, N-dipropylbutan-1 amine (8b) at the dose of 15 mg/kg/day have 90.58% and 88.32% suppression, respectively. All synthetic compounds prolonged the mean survival time of treated mice in comparison with negative control groups, indicating the in vivo antiplasmodial activity of these new compounds. Conclusion: The present study is the first attempt to achieve new, effective synthetic compounds based on phenanthroline scaffold with the antiplasmodial activity. However, more research is needed to optimize their antimalarial activity. PMID- 29456819 TI - Comparison of the efficacy of piascledine and transforming growth factor beta1 on chondrogenic differentiation of human adipose-derived stem cells in fibrin and fibrin-alginate scaffolds. AB - Objectives: The aim of this study was to compare the chondrogenic induction potential of Piascledine and TGF-beta1 on adipose-derived stem cells (ADSCs) in fibrin and fibrin-alginate scaffolds. Materials and Methods: Human subcutaneous adipose tissues were harvested from three patients who were scheduled to undergo liposuction. Isolated ADSCs were proliferated in a culture medium. Then, the cells were seeded in fibrin or fibrin-alginate scaffolds and cultured for 14 days in a chondrogenic medium containing Piascledine, TGF-beta1, or both. The rate of cell proliferation and survival was evaluated by using MTT [3-(4, 5 dimethylthiazolyl-2)-2, 5-diphenyltetrazolium bromide] assay and the rate of the expression of type II collagen, aggrecan, and type X collagen genes was evaluated by real-time polymerase chain reaction (real-time PCR) method. Results: The MTT results showed that Piascledine is able to enhance the proliferation and survival of ADSCs in fibrin scaffolds in comparison to other groups (P<0.05). Real-time PCR evaluation revealed that the expression of type II collagen was higher in TGF beta1groups, but the expression of aggrecan was higher in TGF-beta1 alone or along with Piascledine in fibrin-alginate scaffolds. Furthermore, the expression of type X collagen was lower in Piascledine alone or along with TGF-beta1 in fibrin scaffold. Conclusion: Piascledine can enhance the proliferation and differentiation of ADSCs in fibrin scaffolds. PMID- 29456820 TI - Immunogenicity of heparin-binding hemagglutinin expressed by Pichia pastoris GS115 strain. AB - Objectives: Heparin-binding hemagglutinin (HBHA), a mycobacterial cell surface protein, mediates adhesion to nonphagocytic cells and the dissemination of Mycobacterium tuberculosis (M. tuberculosis) from the site of primary infection. Superior expression systems are required to obtain abundant M. tuberculosis proteins for the purpose of diagnosing M. tuberculosis infection or for the immunization. Here, HBHA was expressed by Pichia pastoris (P. pastoris) GS115 strain , and the immunogenicity of HBHA was evaluated. Materials and Methods: The HBHA gene of M. tuberculosis was cloned into the pPIC9K plasmid, which was good for electroporation into P. pastoris GS115 strain. Unlabeled HBHA protein was purified using a Sepharose CL-6B column, and its expression was confirmed using anti-HBHA polyclonal antibody from mouse serum. We injected C57BL/6 mice with HBHA/ dimethyldioctadecylammonium/trehalose 6,6'-dibehenate (HBHA/DDA/TDB) to investigate the immunogenicity of this potential vaccine. Results: The results demonstrated that HBHA/DDA/TDB has the ability to induce high levels of HBHA specific IgG antibody and its subclasses, as well as interferon-gamma, compared with injection of phosphate-buffered saline, DDA/TDB alone and Bacillus Calmette Guerin (BCG) controls (P<0.05). Moreover, the ratio of IgG2a/IgG1 of the HBHA/DDA/TDB group was higher than that of the BCG group (P<0.05). Conclusion: HBHA with no label has excellent immunogenicity, and is suitable for evaluating the effectiveness to prevent M. tuberculosis infection. PMID- 29456821 TI - Resveratrol decreases apoptosis and NLRP3 complex expressions in experimental varicocele rat model. AB - Objectives: Varicocele is an abnormal dilation in the testicular vein, which can cause hypoxia, reactive oxygen species accumulation, elevation in testicular temperature, and promote apoptosis and increase proinflammatory cytokine production. According to the varicocele pathophysiology, it is possible that a group of cytosolic receptors called nucleotide oligomerization domain (NOD)-like receptor family pyrin domain containing 3 (NLRP3) inflammasomes also involve in varicocele pathogenesis. Due to the important role of antioxidant in decreasing the testis tissue damage, in this study we investigated the protective effect of resveratrol (RES) on NLRP3 complex and apoptosis in experimental varicocele rats. Materials and Methods: In this study, 40 male Wistar rats were randomly divided into 5 groups (8 rats in each group): Control, experimental left varicocele (ELV), ELV + ethanol, ELV + 20 mg/kg RES and ELV + 50 mg/kg RES. Varicocele was induced by partial ligation of the left renal vein. Three months after varicocele induction, RESwas orally administered to rats for 1 month. The expression levels of NLRP3, apoptosis associated speck-like protein (ASC), caspase-1, Bax and Bcl2 were analyzed using real time PCR. Results: Our results showed that RESat both doses significantly (P<= 0.05) decreased the gene expression levels of ASC, NLRP3, caspase-1 and Bax and increased Bcl2 gene expression at high dose. Conclusions: RESby reducing inflammatory factors and decreasing apoptosis might be used as adjuvant therapy to reduce varicocele complication. PMID- 29456822 TI - Self-ear cleaning practices and the associated risk of ear injuries and ear related symptoms in a group of university students. AB - Self-ear cleaning is the insertion of objects into the ear canal to clean it, a widespread practice that has the potential to compromise its integrity as a natural, selfcleansing mechanism, and a risk factor for possible injuries. The practice is common among young adults and highest in university than any other graduates. This study aimed to determine the self-ear cleaning practices and associated risk of injury and related symptoms in undergraduate students at KwaZulu-Natal University. The descriptive survey utilized a self-administered questionnaire. Of the 206 participants that responded, 98% engaged in self-ear cleaning, with 75% indicating that it was beneficial. The commonest method (79.6%) being the use of cotton buds, with an associated injury rate of 2.4%. There was no statistically significant associations between those who used or did not use cotton buds and the symptoms experienced. The complications indicate that self-ear cleaning does pose a risk for injury, necessitating more community information and education. PMID- 29456823 TI - Health hazards related to Soba sewage treatment plant, Sudan. AB - The aim of this study was to determine the health hazards acquired by the residents nearby Soba sewage treatment plant. A descriptive cross-sectional study was carried out in Soba locality, Khartoum, Sudan. An interviewer-administrated questionnaire was assigned to 462 residents of the area living in four geographically distributed squares around the sewage plant. The data was analyzed in SPSS; Cronbach's alpha reliability scale of measurement was used to check the internal validity of six variables related to the quality of life. A logistic regression analysis was used to assess the relationship between the health hazards and the quality of life. Among the 462 residents, difficulty in breathing (37.9%) and nausea (37.2) were the principal health hazards. Moreover, the residents had a satisfactory level of awareness (88.7%) about the health hazards. The utmost impact on the quality of life was psychological (97.2%). It was statistically correlated with the reported factors, which impacted the quality of life in the district as revealed by the Cronbach's alpha reliability test with absenteeism (P=0.026), disability (P=0.014), socialization (P=0.032) and death (P=0.016). A logistic regression analysis revealed chemical hazards had a statistically significant association (P<0.05) with quality of life of the residents of Soba district. The study strongly entails the fact that sewage treatment plants crave exceptional consideration from the concerned responsible authorities, together with the fact that the evolved health threats should be confronted with immense responsibility as soon as possible. PMID- 29456825 TI - Multi-stakeholder perspectives on access, availability and utilization of emergency obstetric care services in Lagos, Nigeria: A mixed-methods study. AB - Globally, Nigeria is the second most unsafe country to be pregnant, with Lagos, its economic nerve center having disproportionately higher maternal deaths than the national average. Emergency obstetric care (EmOC) is effective in reducing pregnancyrelated morbidities and mortalities. This mixed-methods study quantitatively assessed women's satisfaction with EmOC received and qualitatively engaged multiple key stakeholders to better understand issues around EmOC access, availability and utilization in Lagos. Qualitative interviews revealed that regarding access, while government opined that EmOC facilities have been strategically built across Lagos, women flagged issues with difficulty in access, compounded by perceived high EmOC cost. For availability, though health workers were judged competent, they appeared insufficient, overworked and felt poorly remunerated. Infrastructure was considered inadequate and paucity of blood and blood products remained commonplace. Although pregnant women positively rated the clinical aspects of care, as confirmed by the survey, satisfaction gaps remained in the areas of service delivery, care organization and responsiveness. These areas of discordance offer insight to opportunities for improvements, which would ensure that every woman can access and use quality EmOC that is sufficiently available.

AB - A serosurvey of anti-Ebola Zaire virus nucleoprotein IgG prevalence was carried out among Ebola virus disease survivors and their Community Contacts in Bombali District, Sierra Leone. Our data suggest that the specie of Ebola virus (Zaire) responsible of the 2013-2016 epidemic in West Africa may cause mild or asymptomatic infection in a proportion of cases, possibly due to an efficient immune response. PMID- 29456824 TI - A brief review on features of falciparum malaria during pregnancy. AB - Malaria in pregnancy is a serious public health problem in tropical areas. Frequently, the placenta is infected by accumulation of Plasmodium falciparum infected erythrocytes in the intervillous space. Falciparum malaria acts during pregnancy by a range of mechanisms, and chronic or repeated infection and co infections have insidious effects. The susceptibility of pregnant women to malaria is due to both immunological and humoral changes. Until a malaria vaccine becomes available, the deleterious effects of malaria in pregnancy can be avoided by protection against infection and prompt treatment with safe, effective antimalarial agents; however, concurrent infections such as with HIV and helminths during pregnancy are jeopardizing malaria control in sub-Saharan Africa. PMID- 29456827 TI - Impairment of social behaviors in Arhgef10 knockout mice. AB - Background: Impaired social interaction is one of the essential features of autism spectrum disorder (ASD). Our previous copy number variation (CNV) study discovered a novel deleted region associated with ASD. One of the genes included in the deleted region is ARHGEF10. A missense mutation of ARHGEF10 has been reported to be one of the contributing factors in several diseases of the central nervous system. However, the relationship between the loss of ARHGEF10 and the clinical symptoms of ASD is unclear. Methods: We generated Arhgef10 knockout mice as a model of ASD and characterized the social behavior and the biochemical changes in the brains of the knockout mice. Results: Compared with their wild type littermates, the Arhgef10-depleted mice showed social interaction impairment, hyperactivity, and decreased depression-like and anxiety-like behavior. Behavioral measures of learning in the Morris water maze were not affected by Arhgef10 deficiency. Moreover, neurotransmitters including serotonin, norepinephrine, and dopamine were significantly increased in different brain regions of the Arhgef10 knockout mice. In addition, monoamine oxidase A (MAO-A) decreased in several brain regions. Conclusions: These results suggest that ARHGEF10 is a candidate risk gene for ASD and that the Arhgef10 knockout model could be a tool for studying the mechanisms of neurotransmission in ASD. Trial registration: Animal studies were approved by the Institutional Animal Care and Use Committee of National Taiwan University (IACUC 20150023). Registered 1 August 2015. PMID- 29456828 TI - Theoretical models of inhibitory activity for inhibitors of protein-protein interactions: targeting menin-mixed lineage leukemia with small molecules. AB - Development and binding affinity predictions of inhibitors targeting protein protein interactions (PPI) still represent a major challenge in drug discovery efforts. This work reports application of a predictive non-empirical model of inhibitory activity for PPI inhibitors, exemplified here for small molecules targeting the menin-mixed lineage leukemia (MLL) interaction. Systematic ab initio analysis of menin-inhibitor complexes was performed, revealing the physical nature of these interactions. Notably, the non-empirical protein-ligand interaction energy comprising electrostatic multipole and approximate dispersion terms (E(10)El,MTP + EDas) produced a remarkable correlation with experimentally measured inhibitory activities and enabled accurate activity prediction for new menin-MLL inhibitors. Importantly, this relatively simple and computationally affordable non-empirical interaction energy model outperformed binding affinity predictions derived from commonly used empirical scoring functions. This study demonstrates high relevance of the non-empirical model we developed for binding affinity prediction of inhibitors targeting protein-protein interactions that are difficult to predict using empirical scoring functions. PMID- 29456829 TI - Processing of acceleration and dive data on-board satellite relay tags to investigate diving and foraging behaviour in free-ranging marine predators. AB - Biologging technologies are changing the way in which the marine environment is observed and monitored. However, because device retrieval is typically required to access the high-resolution data they collect, their use is generally restricted to those animals that predictably return to land. Data abstraction and transmission techniques aim to address this, although currently these are limited in scope and do not incorporate, for example, acceleration measurements which can quantify animal behaviours and movement patterns over fine-scales.In this study, we present a new method for the collection, abstraction and transmission of accelerometer data from free-ranging marine predators via the Argos satellite system. We test run the technique on 20 juvenile southern elephant seals Mirounga leonina from the Kerguelen Islands during their first months at sea following weaning. Using retrieved archival data from nine individuals that returned to the colony, we compare and validate abstracted transmissions against outputs from established accelerometer processing procedures.Abstracted transmissions included estimates, across five segments of a dive profile, of time spent in prey catch attempt (PrCA) behaviours, swimming effort and pitch. These were then summarised and compared to archival outputs across three dive phases: descent, bottom and ascent. Correlations between the two datasets were variable but generally good (dependent on dive phase, marginal R2 values of between .45 and .6 to >.9) and consistent between individuals. Transmitted estimates of PrCA behaviours and swimming effort were positively biased to those from archival processing.Data from this study represent some of the first remotely transmitted quantifications from accelerometers. The methods presented and analysed can be used to provide novel insight towards the behaviours and movements of free-ranging marine predators, such as juvenile southern elephant seals, from whom logger retrieval is challenging. Future applications could however benefit from some adaption, particularly to reduce positive bias in transmitted PrCA behaviours and swimming effort, for which this study provides useful insight. PMID- 29456830 TI - Hypoxia-induced the upregulation of stromal cell-derived factor 1 in fibroblast like synoviocytes contributes to migration of monocytes into synovium tissue in rheumatoid arthritis. AB - Background: Rheumatoid arthritis (RA) is an auto-immune disease characterized by chronic inflammation of multiple joints. Hypoxia is a constant feature of synovial microenvironment in RA. Fibroblast-like synoviocytes (FLSs), which are potent effector cells in RA. It has been reported that large numbers of monocytes are recruited to the synovium and play an important role in synovial inflammation and tissue destruction in RA. However, the mechanism is still unclear. The aim of this study is to explore the role of hypoxia microenvironment on the recruitment of monocytes and then promote the development of RA. Methods: Rheumatoid arthritis model was constructed. Monocytes and FLSs were isolated from rheumatoid arthritis mice. RT-PCR, western blot and ELISA were used to detect the expression of SDF-1 in FLSs. CXCR4 expression in monocytes was examined by cell immunofluorescence and flow cytometry analysis. Transwell assay was performed to evaluate the potential of cell migration. Results: We demonstrated that hypoxia microenvironment enhanced SDF-1 production of FLSs, which attracted the recruitment of CXCR4-expressing monocytes to the synovium and induced monocytes differentiation into tissue macrophages. Moreover, these macrophages secreted inflammatory factors including IL-6, TNF-alpha, IL-1beta and MMP-3, which contributed to the synovial inflammation and tissue destruction in RA. Conclusion: The results of this study suggested that hypoxia microenvironment played an important role in enhancing SDF-1 production of FLSs. SDF-1/CXCR4 axis was involved in the recruitment of monocytes in RA synovium and it might be a possible way of inhibiting inflammation and bone erosion in RA. PMID- 29456831 TI - Early afterdepolarisation tendency as a simulated pro-arrhythmic risk indicator. AB - Drug-induced Torsades de Pointes (TdP) arrhythmia is of major interest in predictive toxicology. Drugs which cause TdP block the hERG cardiac potassium channel. However, not all drugs that block hERG cause TdP. As such, further understanding of the mechanistic route to TdP is needed. Early afterdepolarisations (EADs) are a cell-level phenomenon in which the membrane of a cardiac cell depolarises a second time before repolarisation, and EADs are seen in hearts during TdP. Therefore, we propose a method of predicting TdP using induced EADs combined with multiple ion channel block in simulations using biophysically-based mathematical models of human ventricular cell electrophysiology. EADs were induced in cardiac action potential models using interventions based on diseases that are known to cause EADs, including: increasing the conduction of the L-type calcium channel, decreasing the conduction of the hERG channel, and shifting the inactivation curve of the fast sodium channel. The threshold of intervention that was required to cause an EAD was used to classify drugs into clinical risk categories. The metric that used L type calcium induced EADs was the most accurate of the EAD metrics at classifying drugs into the correct risk categories, and increased in accuracy when combined with action potential duration measurements. The EAD metrics were all more accurate than hERG block alone, but not as predictive as simpler measures such as simulated action potential duration. This may be because different routes to EADs represent risk well for different patient subgroups, something that is difficult to assess at present. PMID- 29456833 TI - Work-related acute physical injuries, chronic overuse complaints, and the psychosocial work environment in Danish primary care chiropractic practice - a cross-sectional study. AB - Background: Little is known about the physical and psychosocial work environment of chiropractors and their work-related health complaints, and this has never been described for Danish chiropractors. The aim of this study was, therefore, to describe work-related acute physical injuries, overuse complaints, and psychosocial stress in Danish chiropractic work settings. Methods: We developed a questionnaire specifically for this study and distributed it electronically in August 2016 using SurveyXact to all 575 members of the Danish Chiropractors' Association working in primary care clinics. Chiropractors were asked about their work-related acute physical injuries and overuse complaints as well as any psychosocial stress they experienced at work during the previous year. We described our sample and variables using means, medians, ranges, and confidence intervals where appropriate. Statistically significant differences between genders, types of complaints and injuries, and between clinic owners and associates were examined using Chi-square and Fischer's exact tests, where appropriate, or by examining confidence intervals for non-overlap. Results: 355 (65.2%) chiropractors answered the survey. Of these, 216 (61%, 95% CI 56-66) had experienced a work-related acute physical injury and/or overuse complaint during the previous year. Work-related overuse complaints were most commonly reported in the low back, wrist, thumb, and shoulder, and were more common among women (63%, 95% CI 56-70) than men (51%, 95% CI 43-59). Chiropractors with more than five years in practice (59%, 95% CI 52-64) reported significantly fewer work-related acute injuries and overuse complaints during the previous year compared with chiropractors with less than five years in practice (83%, 95% CI 73-91). In general, these practicing Danish chiropractors reported having a good psychosocial work environment, and 90% of chiropractors "always" or "often" felt that they were motivated and committed to their work. Conclusion: This sample of Danish practicing chiropractors commonly reported work-related acute physical injuries or overuse complaints. Overuse complaints were most commonly reported in the low back, wrist, thumb, and shoulder and were more common among women than men. Newly educated chiropractors reported more overuse complaints than experienced chiropractors. Collectively, this sample of Danish chiropractors reported that they had a good psychosocial work environment. PMID- 29456832 TI - Interleukin-25 and eosinophils progenitor cell mobilization in allergic asthma. AB - Background: Eosinophil-lineage committed progenitor cells (EoP) migrate from the bone marrow and differentiate locally to provide an ongoing source of mature eosinophils in asthmatic inflammatory responses in the airways. Sputum levels of EoP are increased in asthmatics compared to normal controls suggesting an exaggerated eosinophilopoietic environment in the airways. Understanding what factors promote EoP traffic to the airways is important to understand the diathesis of asthma pathology. Interleukin (IL)-25, is an epithelial-derived cytokine that promotes type 2 inflammatory responses. We have previously shown that levels of IL-25 and expression of the IL-25 receptor (IL-17RA and IL-17RB) on mature eosinophils are greater in allergic asthmatics compared to atopic non asthmatics and non-atopic normal controls. In addition, these levels were increased significantly increased following allergen inhalation challenge and physiologically relevant levels of IL-25 stimulated eosinophil degranulation, intracellular IL-5 and IL-13 expression and primed migration to eotaxin. The current study, examined the role of IL-25 on allergen-induced trafficking of EoP in atopic asthmatics. Methods: Asthmatics (n = 14) who developed allergen-induced early and late responses were enrolled in the study. Blood was collected at pre- and 24 h post-challenge. At each time point, surface expression of IL-17RA and IL 17RB on EoP was evaluated by flow cytometry. Migration assays examined the effect of IL-25 on EoP chemotactic responses, in vitro. In addition, IL-25 knockout ovalbumin (OVA) sensitized and challenged mice were studied to evaluate in vivo mobilization effects of IL-25 on newly formed EoP and mature eosinophils. Results: There was a significant increase in numbers of blood EoP expressing IL 17RB, 24 h post-allergen inhalation challenge in allergic asthmatics. Pre exposure to IL-25 primed the migrational responsiveness of EoP to stromal cell derived factor 1alpha. In OVA-sensitized mice, knocking out IL-25 significantly alleviated OVA-induced eosinophil infiltration in the airway and newly formed eosinophils were reduced in the lung. Conclusions: The findings of this study indicate a potential role for IL-25 in allergen-induced trafficking of EoP to the airways and local differentiation promoting tissue eosiniophilia in asthmatic responses. PMID- 29456834 TI - A retrospective report (2003-2013) of the complications associated with the use of a one-man (head and tail) rope recovery system in horses following general anaesthesia. AB - Background: The mortality rate of horses undergoing general anaesthesia is high when compared to humans or small animal patients. One of the most critical periods during equine anaesthesia is recovery, as the horse attempts to regain a standing position. This study was performed in a private equine practice in Belgium that uses a purpose-designed one-man (head and tail) rope recovery system to assist the horse during the standing process.The main purpose of the retrospective study was to report and analyse complications and the mortality rate in horses during recovery from anaesthesia using the described recovery system. Information retrieved from the medical records included patient signalment, anaesthetic protocol, duration of anaesthesia, ASA grade, type of surgery, recovery time and complications during recovery. Sedation was administered to all horses prior to recovery with the rope system. Complications were divided into major complications in which the horse was euthanized and minor complications where the horse survived. Major complications were further subdivided into those where the rope system did not contribute to the recovery complication (Group 1) and those where it was not possible to determine if the rope system was of any benefit (Group 2). Results: Five thousand eight hundred fifty two horses recovered from general anaesthesia with rope assistance. Complications were identified in 30 (0.51%). Major complications occurred in 12 horses (0.20%) of which three (0.05%) were assigned to Group 1 and nine (0.15%) to Group 2. Three horses in Group 2 suffered musculoskeletal injuries (0.05%). Eighteen horses (0.31%) suffered minor complications, of which five (0.08%) were categorised as failures of the recovery system. Conclusions: This study reports the major and minor complication and mortality rate during recovery from anaesthesia using a specific type of rope recovery system. Mortality associated with the rope recovery system was low. During recovery from anaesthesia this rope system may reduce the risk of lethal complications, particularly major orthopaedic injuries.

AB - Background: Administration of coronary reperfusion therapy to patients with an acute myocardial infarction (AMI) within the proper timeframe is essential in avoiding clinical complications and death. However, the extent of pre-hospital delay is unexplored in Vietnam. This report aims to describe the duration of pre hospital delay of Hanoi residents hospitalized with a first AMI at the Vietnam National Heart Institute . Methods: A total of 103 Hanoi residents hospitalized at the largest tertiary care medical center in the city for first AMI, who have information on prehospital delay was included in this report. Results: One third of the study sample was women and mean age was 66 years. The mean and median pre hospital delay duration were 14.9 hours and 4.8 hours, respectively. The proportion of patients who delayed <6 , 6-<12, and >= 12 hours were 45%, 13%, and 42%, respectively. Conclusions: Our data shows that a prolonged pre-hospital delay is often observed in patients with a first AMI in Vietnam. In order to confirm these preliminary descriptive findings, a full-scale investigation of all Hanoi residents hospitalized with first AMI is needed. Increasing public awareness about AMI treatment is vital in encouraging patients to seek medical care timely after experiencing AMI symptoms such that received treatment is most effective.

In order to confirm these preliminary descriptive findings, a full-scale investigation of all Hanoi residents hospitalized with first AMI is needed. Increasing public awareness about AMI treatment is vital in encouraging patients to seek medical care timely after experiencing AMI symptoms such that received treatment is most effective.

AB - Background: Astrocytes were conceived for decades only as supporting cells of the brain. However, the observation of Ca2+ waves in astrocyte synctitia, their neurotransmitter receptor expression and gliotransmitter secretion suggested a role in information handling, conception that has some controversies. Synaptic Neuron-Astrocyte metabotropic communication mediated by Inositol tris-phosphate (SN-AmcIP3) is supported by different reports. However, some models contradict this idea and Ca2+ stores are 1000 +/- 325 nm apart from the Postsynaptic Density in the Perisynaptic Astrocyte Projections (PAP's), suggesting that SN-AmcIP3 is extrasynaptic. However, this assumption does not consider IP3 Diffusion Coefficient (Dab), that activates IP3 Receptor (IP3R) releasing Ca2+ from intracellular stores. Results: In this work we idealized a model of a PAP (PAPm) to perform an order of magnitude analysis of IP3 diffusion using a transient mass diffusion model. This model shows that IP3 forms a concentration gradient along the PAPm that reaches the steady state in milliseconds, three orders of magnitude before IP3 degradation. The model predicts that IP3 concentration near the Ca2+ stores may activate IP3R, depending upon Phospholipase C (PLC) number and activity. Moreover, the PAPm supports that IP3 and extracellular Ca2+ entry synergize to promote global Ca2+ transients. Conclusion: The model presented here indicates that Ca2+ stores position in PAP's does not limit SN-AmcIP3. PMID- 29456838 TI - High throughput imaging cytometer with acoustic focussing. AB - We demonstrate an imaging flow cytometer that uses acoustic levitation to assemble cells and other particles into a sheet structure. This technique enables a high resolution, low noise CMOS camera to capture images of thousands of cells with each frame. While ultrasonic focussing has previously been demonstrated for 1D cytometry systems, extending the technology to a planar, much higher throughput format and integrating imaging is non-trivial, and represents a significant jump forward in capability, leading to diagnostic possibilities not achievable with current systems. A galvo mirror is used to track the images of the moving cells permitting exposure times of 10 ms at frame rates of 50 fps with motion blur of only a few pixels. At 80 fps, we demonstrate a throughput of 208 000 beads per second. We investigate the factors affecting motion blur and throughput, and demonstrate the system with fluorescent beads, leukaemia cells and a chondrocyte cell line. Cells require more time to reach the acoustic focus than beads, resulting in lower throughputs; however a longer device would remove this constraint.

AB - Here we report a near infrared, water-soluble, functional and dendrimeric photosensitizer (PS) based on quinoxalinoporphyrazine structure. The photophysical properties and in vitro photodynamic therapy results suggest that this quinoxalinoporphyrazine-based dendrimer may serve as an efficient near infrared (NIR) PS platform. PMID- 29456840 TI - Mixed methods evaluation of the impact of a short term training program on sterile processing knowledge, practice, and attitude in three hospitals in Benin. AB - Background: Proper sterile processing is fundamental to safe surgical practice and optimal patient outcomes. Sterile processing practices in low and middle income countries often fall short of recommended standards. The impact of education and training on sterile processing practices in low and middle-income countries is unknown. We designed a sterile processing education course, including mentoring, and aimed to evaluate the impact on participants' personal knowledge, skills, and practices. We also aimed to identify institutional changes in sterile processing practices at participants' work places. Methods: A mixed methods design study was conducted using a Hospital Sterile Processing Assessment Tool, knowledge tests, and open-ended interviews. Results: Education and mentoring improved how workers understood and approached their work and to what they paid attention. Sterile processing workers were also better able to identify resources available to do their work and showed improved understanding of the impact of their work on patient safety. Conclusions: Health care organizations seeking to improve surgical outcomes can find easy wins requiring minimal cost expenditures by paying attention to sterile processing practices. Investing in education and low-cost resources, such as cleaning detergents and brushes, must be part of any quality improvement initiative aimed at providing safe surgery in low and middle-income countries. PMID- 29456841 TI - Successful treatment of extensively drug-resistant Acinetobacter baumannii ventriculitis with polymyxin B and tigecycline- a case report. AB - Background: Acinetobacter baumannii nosocomial ventriculitis/meningitis, especially those due to drug-resistant strains, has substantially increased over recent years. However, limited therapeutic options exist for the Acinetobacter baumannii ventriculitis/meningitis because of the poor penetration rate of most antibiotics through the blood-brain barrier. Case presentation: A 57-year-old male patient developed ventriculitis from an extensively drug-resistant strain of Acinetobacter baumannii after the decompressive craniectomy for severe traumatic brain injury. The patient was successfully treated with intraventricular and intravenous polymyxin B together with intravenous tigecycline. Conclusions: The case illustrates intraventricular polymyxin B can be a therapeutic option against extensively drug-resistant Acinetobacter baumannii ventriculitis. PMID- 29456843 TI - Analysis of selected policies towards universal health coverage in Uganda: the policy implementation barometer protocol. AB - Background: Policy implementation remains an under researched area in most low and middle income countries and it is not surprising that several policies are implemented without a systematic follow up of why and how they are working or failing. This study is part of a larger project called Supporting Policy Engagement for Evidence-based Decisions (SPEED) for Universal Health Coverage in Uganda. It seeks to support policymakers monitor the implementation of vital programmes for the realisation of policy goals for Universal Health Coverage. A Policy Implementation Barometer (PIB) is proposed as a mechanism to provide feedback to the decision makers about the implementation of a selected set of policy programmes at various implementation levels (macro, meso and micro level). The main objective is to establish the extent of implementation of malaria, family planning and emergency obstetric care policies in Uganda and use these results to support stakeholder engagements for corrective action. This is the first PIB survey of the three planned surveys and its specific objectives include: assessment of the perceived appropriateness of implementation programmes to the identified policy problems; determination of enablers and constraints to implementation of the policies; comparison of on-line and face-to-face administration of the PIB questionnaire among target respondents; and documentation of stakeholder responses to PIB findings with regard to corrective actions for implementation. Methods/Design: The PIB will be a descriptive and analytical study employing mixed methods in which both quantitative and qualitative data will be systematically collected and analysed. The first wave will focus on 10 districts and primary data will be collected through interviews. The study seeks to interview 570 respondents of which 120 will be selected at national level with 40 based on each of the three policy domains, 200 from 10 randomly selected districts, and 250 from 50 facilities. Half of the respondents at each level will be randomly assigned to either face-to-face or on-line interviews. An integrated questionnaire for these interviews will collect both quantitative data through Likert scale-type questions, and qualitative data through open-ended questions. And finally focused dialogues will be conducted with selected stakeholders for feedback on the PIB findings. Secondary data will be collected using data extraction tools for performance statistics. Discussion: It is anticipated that the PIB findings and more importantly, the focused dialogues with relevant stakeholders, that will be convened to discuss the findings and establish corrective actions, will enhance uptake of results and effective health policy implementation towards universal health coverage in Uganda. PMID- 29456842 TI - Hydrogen sulfide, nitric oxide, and neurodegenerative disorders. AB - Hydrogen Sulfide (H2S) and Nitric Oxide (NO) have become recognized as important gaseous signaling molecules with enormous pharmacological effects, therapeutic value, and central physiological roles. NO is one of the most important regulators of the pathophysiological condition in central nervous system (CNS). It is critical in the various functioning of the brain; however, beyond certain concentration/level, it is toxic. H2S was regarded as toxic gas with the smell like rotten egg. But, it is now regarded as emerging neuroprotectant and neuromodulator. Recently, the use of donors and inhibitors of these signaling molecules have helped us to identify their accurate and precise biological effects. The most abundant neurotransmitter of CNS (glutamate) is the initiator of the reaction that forms NO, and H2S is highly expressed in brain. These molecules are shedding light on the pathogenesis of various neurological disorders. This review is mainly focused on the importance of H2S and NO for normal functioning of CNS. PMID- 29456844 TI - An efficient biomarker panel for diagnosis of breast cancer using surface enhanced laser desorption ionization time-of-flight mass spectrometry. AB - Breast cancer (BC) is the most frequently diagnosed cancer that affects women worldwide. Early detection of BC is important to improve survival rates and decrease mortality. The aim of the present study was to investigate serum biomarkers using surface-enhanced laser desorption ionization time-of-flight mass spectrometry (SELDI-TOF-MS) to distinguish patients with BC from the healthy population and patients with benign breast diseases (BBDs). A total of 62 patients with invasive ductal carcinoma, as confirmed by histopathology, and 47 non-cancerous individuals (NCIs) [16 healthy controls (HCs) and 31 patients with BBD] were enrolled in the present study. Serum protein profiles were determined by SELDI-TOF-MS using an immobilized metal affinity capture array. Serum from patients with BC were compared with that from the HC group using univariate and multivariate statistical analyses. A total of 118 clusters were generated from the individual serum. Univariate analysis revealed that 5 peaks were significantly downregulated (m/z 1,452, 2,670, 3,972, 5,354 and 5,523; P<0.001) and 4 were upregulated (m/z 6,850, 7,926, 8,115 and 8,143; P<0.001) in patients with BC compared with the HC group. A comparison of patients with BC and patients with BBD revealed an additional 9 protein peaks. Among these, 3 peaks (m/z 3,972, 5,336 and 11,185) were significantly downregulated and 6 peaks (m/z 4,062, 4,071, 4,609, 6,850, 8,115 and 8,133) were significantly upregulated. A total of 3 peaks [mass-to-change ratio (m/z) 3,972, 6,850 and 8,115 (BC2)] were common in both sets. The results of the present study suggest that a 4 protein peak set [m/z 3,972, 6,850 and 8,115 (BC2) and 8,949 (BC3)] could be used to distinguish patients with BC from NCI. PMID- 29456845 TI - Low carbonyl reductase 1 expression is associated with poor prognosis in patients with oral squamous cell carcinoma. AB - Carbonyl reductase 1 (CBR1) is an enzyme that catalyzes the reduction of numerous compounds by using NADPH-dependent oxidoreductase activity. Decreased expression of CBR1 is associated with disease progression and an unfavorable outcome in several types of malignancies. The purpose of the current study was to determine whether CBR1 expression could be a useful prognostic factor in patients with oral squamous cell carcinoma (OSCC). Therefore, its mechanisms of action were investigated in order to understand how CBR1 affects cancer cell behavior in vitro. CBR1 expression was evaluated using immunohistochemistry and tissue samples obtained from 90 patients with OSCC. The associations between CBR1 expression, clinicopathological characteristics and patient survival were also analyzed. In addition, the role of CBR1 in cancer cell invasion and metastasis was examined, along with its underlying molecular mechanisms, via transfecting CBR1-siRNA into the HSC2 human OSCC cell line. Immunohistochemical analysis revealed that biopsy tissue samples of 71.1% of the patients with OSCC were positive for CBR1. In addition, CBR1 expression status was correlated with the N classification (P<0.0001), stage (P=0.0018) and outcome (P=0.0095). Furthermore, a statistical correlation was determined between the protein expression status and overall survival (P=0.0171). In vitro studies indicated that the suppression of CBR1 by CBR1-siRNA increased cancer cell proliferative, wound healing and migratory abilities. These findings suggest that low expression levels of CBR1 may affect cancer prognosis, and that CBR1 may have potential as a prognostic factor for patients with OSCC. PMID- 29456846 TI - L-Carnitine supplementation reduces the general fatigue of cancer patients during chemotherapy. AB - L-Carnitine (LC) plays an important role in the metabolism of fatty acids, and LC deficiency is associated with a feeling of weakness or general fatigue. Cancer patients receiving chemotherapy often develop LC deficiency, which is considered to be a factor contributing to general fatigue. The aim of the present study was to evaluate the efficacy of LC supplementation as a treatment for general fatigue in cancer patients during chemotherapy. A total of 11 cancer patients who were suffering from general fatigue during chemotherapy in our hospital between September 2014 and December 2015 were examined (6 cases involved adjuvant chemotherapy and 5 cases involved chemotherapy for unresectable or recurrent disease). The patients were administered 1,500 mg/day of levocarnitine per os, and the change in mean daily fatigue from the baseline to 8 weeks was assessed using the Brief Fatigue Inventory. The change in the plasma levels of albumin and the lymphocyte counts from the baseline to 8 weeks were also assessed. LC supplementation reduced general fatigue in all cases. Moreover, LC supplementation maintained the plasma levels of albumin and lymphocyte counts during chemotherapy, and enabled patients to continue chemotherapy sequentially without dose reduction. Therefore, LC supplementation improved general fatigue in all the examined cancer patients during chemotherapy. This treatment may make improve the tolerability of chemotherapy in cancer patients by reducing general fatigue and improving the nutritional status. PMID- 29456847 TI - Curative resection of pancreatic ductal adenocarcinoma developing in the remnant pancreas 13 years after distal pancreatectomy for intraductal papillary mucinous neoplasms: A case report. AB - Intraductal papillary mucinous neoplasms (IPMNs) are characterized by the papillary proliferation of atypical mucinous epithelial cells in the pancreatic ductal system. There are two recurrence patterns following resection of IPMNs: Metachronous multifocal occurrence of IPMNs, and distinct pancreatic ductal adenocarcinoma (PDAC) in the remnant pancreas. Several recent studies investigated the development of distinct PDAC during follow-up evaluation of IPMNs and the incidence rate ranged from 4.5 to 8%. Thus, IMPNs may be a good predictor for the early detection of PDAC during observation or after the resection of IPMNs. We herein report the rare case of a patient who underwent resection of PDAC that developed in the remnant pancreas 13 years after distal pancreatectomy with splenectomy for IPMNs. PDAC may develop in the remnant pancreas after pancreatectomy for IPMNs; thus, careful long-term follow-up with periodic surveillance, at least every 6 months, is warranted. PMID- 29456849 TI - High preoperative Glasgow prognostic score is a negative prognostic factor for patients with endometrial carcinoma. AB - The aim of the present study was to determine the prognostic value of the Glasgow prognostic score (GPS) in endometrial carcinoma (EC). Patients with EC who underwent surgery at the Shimane University Hospital between January 1997 and December 2013 were enrolled (n=118). The associations between pretreatment GPS and clinical parameters, including age, histological type, International Federation of Gynecology and Obstetrics stage, tumor grade, carbohydrate antigen 19-9 and carcinoembryonic antigen levels, progression-free survival (PFS), and overall survival (OS), were investigated. Survival analysis was performed with the Kaplan-Meier method, and prognostic factors were evaluated with Cox's proportional hazards regression model. A high pretreatment GPS was associated with advanced clinical stage, histological type and tumor grade (P<0.001, P=0.007 and P=0.006, respectively). Multivariate analysis identified a high GPS as an independent negative prognostic factor for PFS and OS (P=0.025 and P=0.044, respectively). Therefore, a high pretreatment GPS has prognostic value and the potential to be a predictive marker for surgical outcome in patients with EC. Evaluation of pretreatment GPS may aid in the identification of high-risk populations, which may improve treatment selection and patient outcomes. PMID- 29456848 TI - Survival-associated factors of first-line EGFR-tyrosine kinase inhibitor responders and non-responders in lung adenocarcinoma patients with common EGFR mutations. AB - The aim of the present retrospective cohort study was to elucidate the clinical presentation of epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI) responders and non-responders in lung adenocarcinoma patients with common EGFR mutations. The cohort included 131 lung adenocarcinoma patients with common exon 19 or exon 21 EGFR mutations, who were receiving first-line EGFR-TKI therapy. The patient characteristics, treatment regimen and outcomes were recorded and analyzed. Of the 131 patients, 104 (79.3%) responded to treatment, while 27 (20.7%) did not. A significantly longer median progression-free survival (PFS) [14.3, 95% confidence interval (CI): 12.2-18.4 vs. 5.7, 95% CI: 2.7-9.9 months; P<0.001] and overall survival (OS) (42.2, 95% CI: 28.1-58.1 vs. 11.5, 95% CI: 8.3-19.7 months; P<0.001) were observed in responders compared with non responders. In responders, bone [hazard ratio (HR)=1.87, 95% CI: 1.11-3.20, P=0.021] and pleural (HR=2.40, 95% CI: 1.37-4.22, P=0.002) metastasis were independent factors of PFS. Exon 19 mutations (HR=0.38, 95% CI: 0.19-0.76, P=0.006), Eastern Cooperative Oncology Group performance status score >=2 (HR=3.53, 95% CI: 1.42-8.75, P=0.007) and bone metastasis (HR=2.01, 95% CI: 1.05 3.85, P=0.034), were independent factors of OS. In non-responders, smoking (HR=3.97, 95% CI: 1.13-13.91, P=0.031) was an independent factor of PFS. Different survival-associated factors were observed between EGFR-TKI responders and non-responders. The development of new treatment strategies should be advocated in EGFR-TKI non-responders. PMID- 29456850 TI - 18F-fluorodeoxyglucose positron emission tomography/computed tomography for the prediction of survival in patients with advanced esophageal cancer who have undergone neoadjuvant chemotherapy. AB - Neoadjuvant chemotherapy (NAC) is a promising treatment strategy for advanced esophageal cancer. However, measures of NAC response assessment and prognostic prediction have not yet been established. The aim of this study was to evaluate the usefulness of combined 18F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT). A total of 77 patients with stage IB-IV esophageal cancer who were treated with NAC followed by curative resection were retrospectively analyzed. PET/CT was performed before and after NAC and 56 patients were clinical responders. The pretreatment maximal standardized uptake value (pre-SUVmax), post-SUVmax and %SUVmax were 11.3+/-5.8, 5.1+/-4.8 and 49.0+/ 35.1%, respectively, for the main tumors (T) and 4.3+/-2.8, 2.5+/-1.9 and 67.0+/ 39.6%, respectively, for the metastatic nodes (N). Among the preoperatively available factors, clinical response (P=0.018), post-SUVmax-N (P=0.0001) and %SUVmax-T (P=0.0031) were significant prognostic factors by univariate analysis. The multivariate analysis identified post-SUVmax-N as the only significant prognostic predictor (P=0.0254). Patients with a post-SUVmax-N of <3.0 exhibited significantly fewer pathological metastatic nodes and better disease-free survival compared with patients with a post-SUVmax-N >3.0. Therefore, post-SUVmax N may be a useful prognostic predictor in patients with advanced esophageal cancer who are treated with NAC followed by surgery. PMID- 29456851 TI - Duodenal mucinous adenocarcinoma presenting as ileus, obstructive jaundice and massive ascites: A case report. AB - Duodenal mucinous adenocarcinoma (DMA) is a malignancy with a rather low morbidity. However, its incidence in China has not been clearly determined. We herein report a case of a 70-year-old female patient who presented with ileus, obstructive jaundice and massive ascites simultaneously. Gastroendoscopy revealed copious amounts of colloidal mucin in the gastric cavity. The neoplasm was not visualized on computed tomography or magnetic resonance imaging, and an exploratory laparotomy was performed to investigate the abdomen. During the operation, the anterior wall of the gastric antrum was incised to explore the first and second portions of the duodenum, as well as the gastric lumen, and a neoplasm sized ~2.0 cm was identified at the antimesenteric border of the duodenal bulb after clearing the colloidal mucin content of the stomach and duodenum. Gastrojejunostomy rather than radical resection was performed due to the poor condition of the patient. The postoperative histopathological examination of the colloidal substance removed from the duodenal cavity revealed mucinous adenocarcinoma. On immunohistochemical analysis, the tissue stained positive for pan-cytokeratin, cytokeratin 19, CDX-2, carcinoembryonic antigen and Ki-67 (8%), and negative for excision repair-1. The general condition of the patient postoperatively was poor; thus, adjuvant chemotherapy was not administered and the patient finally succumbed to the disease 42 days after surgery. PMID- 29456852 TI - Xanthogranulomatous pituitary adenoma: A case report and literature review. AB - Xanthogranuloma, also referred to as cholesterol granuloma or xanthogranulomatous reaction, is a granulomatous lesion that is infrequently found in the sellar and parasellar regions. Xanthogranulomatous pituitary adenoma is relatively rare and, thus, the etiology, diagnosis, management and prognosis of this condition remain incompletely understood. We herein report the case of a 56-year-old female patient who presented to our institution with intermittent headache, vomiting and distending pain in the bilateral orbital regions. Brain magnetic resonance imaging revealed a sellar mass with a heterogeneous signal. The mass was subtotally resected, and histopathological examination confirmed the diagnosis of xanthogranulomatous pituitary adenoma. Although the patient's symptoms were relieved following surgical treatment, intractable hyponatremia and diabetes insipidus developed and she received hormone replacement therapy. At the last follow-up (November 2016), the patient remained recurrence-free. A total of 14 cases of pituitary adenoma with concomitant xanthogranuloma were identified in the literature, and the clinical and radiological manifestations are discussed. Sellar xanthogranuloma is usually associated with craniopharyngioma or Rathke's cleft cyst; however, it may also occur in isolation. Xanthogranulomatous pituitary adenomas are infrequent, making their diagnosis challenging. Surgical resection is the preferred treatment, and attention should be paid to postoperative hypopituitarism and development of diabetes insipidus. PMID- 29456853 TI - Crizotinib-associated toxic epidermal necrolysis in an ALK-positive advanced NSCLC patient. AB - Crizotinib is an oral small-molecule inhibitor of anaplastic lymphoma kinase (ALK) tyrosine-kinase that has been approved for treating patients with advanced echinoderm microtubule associated protein like 4-ALK rearranged non-small-cell lung cancer (NSCLC). Toxic epidermal necrolysis (TEN) is a rare adverse event associated with crizotinib. The present study reported a case of a 75-year-old Chinese male patient with advanced NSCLC with ALK fusion, who developed TEN after 56 days of crizotinib treatment and demised due to this dermatological adverse event. The occurrence of severe cutaneous necrolysis that predominantly involves the skin and mucous membranes during crizotinib treatment should alert clinicians to be aware of TEN and take prompt actions. PMID- 29456854 TI - Novel BRAF mutation in melanoma: A case report. AB - In melanoma, a number of specific genetic and genomic aberrations have been identified to be important in tumorigenesis. In particular, the mutant B-Raf proto-oncogene, Serine/Threonine kinase (BRAF) gene is the target of tailored therapy with kinase inhibitor molecules. Identification of the array of mutations in patients with melanoma will be useful in determining a genetic profile of the tumor with potential implications for treatment decisions. A rare aminoacidic insertion in codon 599 of the BRAF gene (c.1797_1798insACA, T599insT) was detected by using both direct (Sanger) sequencing and pyrosequencing techniques in a metastatic melanoma of a female elderly patient. As suggested in other clinical contexts including pilocytic astrocytoma, papillary thyroid carcinomas and anaplastic thyroid carcinomas, this unusual mutation may be associated with a modified spatial structure of activated P-loop, resulting in a constitutional activation of the BRAF protein. The patient died shortly following the test, thus no biological therapy was performed. Comparable data regarding treatment of melanoma patients with rare BRAF mutations is lacking, and the response to BRAF inhibitors requires further investigation. PMID- 29456855 TI - Metformin and aspirin treatment could lead to an improved survival rate for Type 2 diabetic patients with stage II and III colorectal adenocarcinoma relative to non-diabetic patients. AB - Metformin, the drug of choice in the treatment of type 2 diabetes mellitus (DM2), in addition to aspirin (ASA), the drug prescribed for cardioprotection of diabetic and non-diabetic patients, have an inhibitory effect on cancer cell survival. The present population-based study conducted in the province of Trieste (Italy), aimed to investigate the prevalence of DM2 in patients with colorectal adenocarcinoma (CRC) and survival for CRC in diabetic and nondiabetic patients. All permanent residents diagnosed with a CRC between 2004 and 2007 were ascertained through the regional health information system. CRC-specific and relative survival probabilities were computed for each group of patients defined by CRC stage, presence or absence of DM2 treated with metformin, and presence or absence of daily ASA therapy. A total of 515 CRC patients without DM2 and 156 with DM2 treated with metformin were enrolled in the study. At the time of CRC diagnosis, 71 (14%) nondiabetic and 39 (25%) diabetic patients were taking ASA daily. The five-year relative survival for stage III CRC was 101% [95% confidence interval (CI)=76-126] in the 18 patients with DM2 treated with metformin and ASA, 55% (95% CI=31-78) in the 23 without DM2 treated with ASA, 55% (95% CI=45-65) in the 150 without DM2 not taking ASA, and 29% (95% CI=13-45) in the 43 with DM2 treated with metformin, however not with ASA. The findings support the hypothesis of a possible inhibitory effect of metformin and ASA on CRC cells. Randomized controlled trials are required to verify this hypothesis. PMID- 29456856 TI - Design principles of perovskites for solar-driven thermochemical splitting of CO2. AB - Perovskites are attractive redox materials for thermo/electrochemical fuel synthesis. To design perovskites with balanced redox energetics for thermochemically splitting CO2, the activity of lattice oxygen vacancies and stability against crystal phase changes and detrimental carbonate formation are predicted for a representative range of perovskites by electronic structure computations. Systematic trends in these materials properties when doping with selected metal cations are described in the free energy range defined for isothermal and temperature-swing redox cycles. To confirm that the predicted materials properties root in the bulk chemical composition, selected perovskites are synthesized and characterized by X-ray diffraction, transmission electron microscopy, and thermogravimetric analysis. On one hand, due to the oxidation equilibrium, none of the investigated compositions outperforms non-stoichiometric ceria - the benchmark redox material for CO2 splitting with temperature-swings in the range of 800-1500 degrees C. On the other hand, certain promising perovskites remain redox-active at relatively low oxide reduction temperatures at which ceria is redox-inactive. This trade-off in the redox energetics is established for YFeO3, YCo0.5Fe0.5O3 and LaFe0.5Ni0.5O3, identified as stable against phase changes and capable to convert CO2 to CO at 600 degrees C and 10 mbar CO in CO2, and to being decomposed at 1400 degrees C and 0.1 mbar O2 with an enthalpy change of 440-630 kJ mol-1 O2. PMID- 29456857 TI - Platinum-free, graphene based anodes and air cathodes for single chamber microbial fuel cells. AB - Microbial fuel cells (MFCs) exploit the ability of microorganisms to generate electrical power during metabolism of substrates. However, the low efficiency of extracellular electron transfer from cells to the anode and the use of expensive rare metals as catalysts, such as platinum, limit their application and scalability. In this study we investigate the use of pristine graphene based electrodes at both the anode and the cathode of a MFC for efficient electrical energy production from the metabolically versatile bacterium Rhodopseudomonas palustris CGA009. We achieve a volumetric peak power output (PV) of up to 3.51 +/ 0.50 W m-3 using graphene based aerogel anodes with a surface area of 8.2 m2 g 1. We demonstrate that enhanced MFC output arises from the interplay of the improved surface area, enhanced conductivity, and catalytic surface groups of the graphene based electrode. In addition, we show a 500-fold increase in PV to 1.3 +/- 0.23 W m-3 when using a graphene coated stainless steel (SS) air cathode, compared to an uncoated SS cathode, demonstrating the feasibility of a platinum free, graphene catalysed MFCs. Finally, we show a direct application for microwatt-consuming electronics by connecting several of these coin sized devices in series to power a digital clock. PMID- 29456858 TI - Enhanced biostability and cellular uptake of zinc oxide nanocrystals shielded with a phospholipid bilayer. AB - The widespread use of ZnO nanomaterials for biomedical applications, including therapeutic drug delivery or stimuli-responsive activation, as well as imaging, imposes a careful control over the colloidal stability and long-term behaviour of ZnO in biological media. Moreover, the effect of ZnO nanostructures on living cells, in particular cancer cells, is still under debate. This paper discusses the role of surface chemistry and charge of zinc oxide nanocrystals, of around 15 nm in size, which influence their behaviour in biological fluids and effect on cancer cells. In particular, we address this problem by modifying the surface of pristine ZnO nanocrystals (NCs), rich of hydroxyl groups, with positively charged amino-propyl chains or, more innovatively, by self-assembling a double-lipidic membrane, shielding the ZnO NCs. Our findings show that the prolonged immersion in simulated human plasma and in the cell culture medium leads to highly colloidally dispersed ZnO NCs only when coated by the lipidic bilayer. In contrast, the pristine and amine-functionalized NCs form huge aggregates after already one hour of immersion. Partial dissolution of these two samples into potentially cytotoxic Zn2+ cations takes place, together with the precipitation of phosphate and carbonate salts on the NCs' surface. When exposed to living HeLa cancer cells, higher amounts of lipid-shielded ZnO NCs are internalized with respect to the other samples, thus showing a reduced cytotoxicity, based on the same amount of internalized NCs. These results pave the way for the development of novel theranostic platforms based on ZnO NCs. The new formulation of ZnO shielded with a lipid-bilayer will prevent strong aggregation and premature degradation into toxic by-products, and promote a highly efficient cell uptake for further therapeutic or diagnostic functions. PMID- 29456859 TI - Acute myeloid leukemia in a father and son with a germline mutation of ASXL1. AB - Background: Myelodysplastic syndromes and acute myeloid leukemia usually occur sporadically in older adults. More recently cases of familial acute myeloid leukemia and/or myelodysplastic syndrome have been reported. Case presentation: Currently we report a father and son who both developed myelodysplastic syndrome that progressed to acute myeloid leukemia. Both patients were found to have the identical mutation of ASXL1 on nextgen sequencing of both hematologic and nonhematologic tissues.

AB - Conventional treatments for acute leukemia include chemotherapy, radiation therapy, and intensive combined treatments (including bone marrow transplant or stem cell transplants). Novel treatment approaches are in active development. Recently, protein kinase inhibitors are on clinical trials and offer hope as new drugs for acute leukemia treatment. This review will provide a brief summary of the protein kinase inhibitors in clinical applications for acute leukemia treatment. PMID- 29456861 TI - Critical airway compression caused by a large mediastinal tumour with spontaneous haemorrhage. AB - We report the case of a 77-year-old woman presenting with out-of-hospital cardiac arrest, which was then interpreted as an acute, life-threatening critical airway compression by a huge mediastinal tumour without appropriate diagnosis. Emergency extracorporeal membrane oxygenation was cannulated for sufficient respiratory support after spontaneous circulation was regained. After the multidisciplinary team, involving thoracic surgeons, discussed the resectability of the mediastinal tumour, the patient underwent successful resection of the mediastinal tumour through a median sternotomy. The pathological report demonstrated an intrathoracic goitre with spontaneous haemorrhage and haematoma formation, and the patient was discharged with favourable respiratory and neurological outcomes. PMID- 29456862 TI - Thin laryngeal foreign bodies in infants: diagnostic potential of MDCT. AB - A laryngeal foreign body (FB) is a significant, life-threatening event in the paediatric population. Incomplete airways obstruction by a thin, laminar, radiolucent FB lodged in the glottis or supraglottis is a rare occurrence that may present with non-specific symptoms, absence of chest findings, and normal radiographic investigations, resulting in misdiagnosis, delay in diagnosis, or prolonged recovery. We report two cases of 10-month-old male infants, each with a thin radiolucent FB lodged between the vocal folds that was detected with low dose multidetector computed tomography (MDCT) and thin-slice reconstruction. Both infants presented with symptoms of respiratory airway inflammation at clinical examination and negative neck and chest radiographs. FBs were removed by direct laryngoscopy, without complications. In our experience, low-dose MDCT with thin slice reconstruction is particularly useful for diagnosis in cases of suspected FB aspiration with uncertain clinical presentation and negative radiographic exams. PMID- 29456863 TI - Lung parenchymal involvement of primary bone marrow follicular lymphoma: a rare case study. AB - A 76-year-old man presented with shortness of breath. Computed tomography revealed ground-glass opacity and interlobular thickening in the right lower lobe. Blood examination showed elevated levels of white blood cell count and lymphocytes. Bone marrow aspiration revealed low-grade follicular lymphoma. Histopathological examination of the surgical lung biopsy from the right lower lobe demonstrated usual interstitial pneumonia and scattered aggregation of lymphocytes with poorly formed non-necrotizing granuloma. An 18F fluorodeoxyglucose positron emission tomography-computed tomography (18F-FDG PET CT) did not show intense uptake in areas other than the right lower lobe. We concluded that the granuloma in the lung was presumed to be a sarcoid reaction associated with bone marrow follicular lymphoma, and the intense 18F-FDG uptake in the right lower lobe might have been due to a sarcoid reaction. Immunohistochemistry or other genetic examinations are important even if 18F-FDG uptake on PET-CT seems to be a false-positive because of the possibility of a sarcoid reaction. PMID- 29456865 TI - A real world example of coverage with evidence development in Australia - ipilimumab for the treatment of metastatic melanoma. AB - Background: Australian Government subsidisation of ipilimumab for the treatment of patients with metastatic melanoma was conditional on the sponsor entering a 'managed entry scheme' to assess the 2-year overall survival rate in metastatic melanoma patients who received ipilimumab in the first year of Pharmaceutical Benefits Scheme listing. Methods: All unresectable stage IIIc / IV metastatic melanoma patients treated with at least one dose of ipilimumab therapy in Australia from the PBS listing date to a time point 12 months later (i.e. from 1 Aug-2013 to 31-Jul-2014) were invited to participate. Overall survival at 2 years post treatment initiation was measured, with Cox regression analysis used to examine the relationship between survival and patient baseline characteristics. Results: The evaluable population (910 patients) was on average 63.3 years old, male (70.1%) and treated in a public hospital (64.4%) in an urban area (76.5%). The majority of patients were treatment naive (63.3%), did not have brain metastases (71.1%), and were classified as ECOG performance status 0 or 1 (90.4%). The 2 year overall survival rate was conservatively calculated to be at least 23.9% and potentially as high as 34.2%. A significant difference in overall survival at 2 years was demonstrated across the categories of ECOG performance status (p < 0.0001), M-status (p = 0.0005) and treatment status (p = 0.0114). No statistical difference in survival rate was observed when examining brain metastases vs no brain metastases (p = 0.2622), treatment at private vs public hospitals (p = 0.7601) nor treatment in the urban vs rural setting (p = 0.5048). Conclusions: The 2 year overall survival rate for all patients receiving PBS subsidised ipilimumab in Australia from the first year Pharmaceutical Benefits Scheme cohort is estimated to be between 23.9% and 34.2%, which is higher than the 23.5% observed in the key ipilimumab registrational trial. Results and learnings from the ipilimumab 'managed entry scheme' illustrate that early access with the promise of future evidence to confirm a medicine's cost-effectiveness can work, but needs to be carefully considered, constructed and managed.

PMID- 29456864 TI - Curative GnRHa treatment has an unexpected repressive effect on Sertoli cell specific genes. AB - Background: Follicle stimulating hormone and testosterone stimulate Sertoli cells to support germ cell function and differentiation. During mini-puberty, when gonadotropin (GnRH) stimulates increases in plasma luteinizing hormone (LH) and testosterone levels, gonocytes are transformed into Ad spermatogonia. In cryptorchidism, impaired gonadotropin secretion during mini-puberty results in insufficient LH and testosterone secretion, impaired gonocyte transition to Ad spermatogonia, and perturbed Sertoli cell proliferation. Treatment with a gonadotropin-releasing hormone agonist (GnRHa/Buserelin) induced gonocytes to differentiate into Ad spermatogonia and rescued fertility. The present study evaluated the impact of low LH secretion on Sertoli cell function by comparing differential gene expression data between testes with low LH that lacked Ad spermatogonia (Ad-) and testes that completed mini-puberty (Ad+). Furthermore, we analyzed changes in the transcription of selected Sertoli cell specific genes in response to GnRHa treatment. Results: Ad- testes showed reduced expression of nine out of 40 selected Sertoli cell specific genes compared to Ad+ testes. GnRHa treatment repressed most of the Sertoli cell specific genes, including the inhibins, but it increased the expression of genes that regulate apoptosis (FASLG) and proliferation (GDNF). Conclusions: Impaired-minipuberty with decreased LH and testosterone levels affected Ad and Sertoli cell development through positive and negative regulation of morphoregulatory and apoptotic genes. GnRHa treatment had a repressive effect on most Sertoli cell specific genes, which suggested that Sertoli cells underwent a cellular rearrangement. We propose that gonadotropin-dependent increases in FASLG and GDNF expression drove Sertoli cell proliferation and germ cell self-renewal and supported the transition of gonocytes to Ad spermatogonia, independent of inhibins. PMID- 29456867 TI - Heterologous and endogenous U6 snRNA promoters enable CRISPR/Cas9 mediated genome editing in Aspergillus niger. AB - Background: U6 promoters have been used for single guide RNA (sgRNA) transcription in the clustered regularly interspaced short palindromic repeats/CRISPR-associated protein (CRISPR/Cas9) genome editing system. However, no available U6 promoters have been identified in Aspergillus niger, which is an important industrial platform for organic acid and protein production. Two CRISPR/Cas9 systems established in A. niger have recourse to the RNA polymerase II promoter or in vitro transcription for sgRNA synthesis, but these approaches generally increase cloning efforts and genetic manipulation. The validation of functional RNA polymerase II promoters is therefore an urgent need for A. niger. Results: Here, we developed a novel CRISPR/Cas9 system in A. niger for sgRNA expression, based on one endogenous U6 promoter and two heterologous U6 promoters. The three tested U6 promoters enabled sgRNA transcription and the disruption of the polyketide synthase albA gene in A. niger. Furthermore, this system enabled highly efficient gene insertion at the targeted genome loci in A. niger using donor DNAs with homologous arms as short as 40-bp. Conclusions: This study demonstrated that both heterologous and endogenous U6 promoters were functional for sgRNA expression in A. niger. Based on this result, a novel and simple CRISPR/Cas9 toolbox was established in A. niger, that will benefit future gene functional analysis and genome editing. PMID- 29456869 TI - Cognitive fluctuations in Parkinson's disease dementia: blood pressure lability as an underlying mechanism. AB - Background: Cognitive fluctuations refer to alterations in cognition, attention, or arousal occurring over minutes to hours, most commonly in patients with dementias associated with advanced Lewy body pathology. Their pathophysiologic underpinning remains undetermined. Case presentation: We documented serial blood pressure (BP) measurements in an 86-year-old man with Parkinson's disease dementia experiencing cognitive fluctuations during an office visit. This patient's associated dysautonomia included labile BP with orthostatic hypotension and nocturnal hypertension. A spontaneous episode of unresponsiveness occurred while his BP was 72/48. His mental status began to recover immediately as his BP increased to 84/56 when he was placed in a recumbent position; it fully returned to baseline when it reached 124/66 within 1 min. His heart rate remained in the mid-to-high 60s throughout. Subsequent treatment with midodrine markedly reduced the frequency of cognitive fluctuations. Conclusions: Paroxysmal hypotension may represent an explanatory mechanism for cognitive fluctuations, a common clinical feature in patients with Parkinson's disease dementia and dementia with Lewy bodies.

AB - Background: Cinnamon (Cinnamomum zeylanicum) bark extract exhibits potent inhibitory activity against Candida albicans but the antifungal mechanisms of this essential oil remain largely unexplored. Results: We analyzed the impact of cinnamon bark oil on C. albicans RSY150, and clinical strains isolated from patients with candidemia and candidiasis. The viability of RSY150 was significantly compromised in a dose dependent manner when exposed to cinnamon bark oil, with extensive cell surface remodelling at sub inhibitory levels (62.5 MUg/mL). Atomic force microscopy revealed cell surface exfoliation, altered ultrastructure and reduced cell wall integrity for both RSY150 and clinical isolates exposed to cinnamon bark oil. Cell wall damage induced by cinnamon bark oil was confirmed by exposure to stressors and the sensitivity of cell wall mutants involved in cell wall organization, biogenesis, and morphogenesis. The essential oil triggered cell cycle arrest by disrupting beta tubulin distribution, which led to mitotic spindle defects, ultimately compromising the cell membrane and allowing leakage of cellular components. The multiple targets of cinnamon bark oil can be attributed to its components, including cinnamaldehyde (74%), and minor components (< 6%) such as linalool (3.9%), cinamyl acetate (3.8%), alpha-caryophyllene (5.3%) and limonene (2%). Complete inhibition of the mitotic spindle assembly was observed in C. albicans treated with cinnamaldehyde at MIC (112 MUg/mL). Conclusions: Since cinnamaldehyde disrupts both the cell wall and tubulin polymerization, it may serve as an effective antifungal, either by chemical modification to improve its specificity and efficacy or in combination with other antifungal drugs. PMID- 29456870 TI - A psychosocial intervention for the management of functional dysphonia: complex intervention development and pilot randomised trial. AB - Background: Medically unexplained loss or alteration of voice-functional dysphonia-is the commonest presentation to speech and language therapists (SLTs). Besides the impact on personal and work life, functional dysphonia is also associated with increased levels of anxiety and depression and poor general health. Voice therapy delivered by SLTs improves voice but not these associated symptoms. The aims of this research were the systematic development of a complex intervention to improve the treatment of functional dysphonia, and the trialling of this intervention for feasibility and acceptability to SLTs and patients in a randomised pilot study. Methods: A theoretical model of medically unexplained symptoms (MUS) was elaborated through literature review and synthesis. This was initially applied as an assessment format in a series of patient interviews. Data from this stage and a small consecutive cohort study were used to design and refine a brief cognitive behavioural therapy (CBT) training intervention for a SLT. This was then implemented in an external pilot patient randomised trial where one SLT delivered standard voice therapy or voice therapy plus CBT to 74 patients. The primary outcomes were of the acceptability of the intervention to patients and the SLT, and the feasibility of changing the SLT's clinical practice through a brief training. This was measured through monitoring treatment flow and through structured analysis of the content of intervention for treatment fidelity and inter-treatment contamination. Results: As measured by treatment flow, the intervention was as acceptable as standard voice therapy to patients. Analysis of treatment content showed that the SLT was able to conduct a complex CBT formulation and deliver novel treatment strategies for fatigue, sleep, anxiety and depression in the majority of patients. On pre-post measures of voice and quality of life, patients in both treatment arms improved. Conclusion: These interventions were acceptable to patients. Emotional and psychosocial issues presented routinely in the study patient group and CBT techniques were used, deliberately and inadvertently, in both treatment arms. This CBT "contamination" of the voice therapy only arm reflects the chief limitation of the study: one therapist delivered both treatments.

PMID- 29456872 TI - Accuracy in local staging of prostate cancer by adding a three-dimensional T2 weighted sequence with radial reconstructions in magnetic resonance imaging. AB - Background: The evidence supporting the use of magnetic resonance imaging (MRI) in prostate cancer detection has been established, but its accuracy in local staging is questioned. Purpose: To investigate the additional value of multi planar radial reconstructions of a three-dimensional (3D) T2-weighted (T2W) MRI sequence, intercepting the prostate capsule perpendicularly, for improving local staging of prostate cancer. Material and Methods: Preoperative, bi-parametric prostate MRI examinations in 94 patients operated between June 2014 and January 2015 where retrospectively reviewed by two experienced abdominal radiologists. Each patient was presented in two separate sets including diffusion-weighted imaging, without and with the 3D T2W set that included radial reconstructions. Each set was read at least two months apart. Extraprostatic tumor extension (EPE) was assessed according to a 5-point grading scale. Sensitivity and specificity for EPE was calculated and presented as receiver operating characteristics (ROC) with area under the curve (AUC), using histology from whole-mount prostate specimen as gold standard. Inter-rater agreement was calculated for the two different reading modes using Cohen's kappa. Results: The AUC for detection of EPE for Readers 1 and 2 in the two-dimensional (2D) set was 0.70 and 0.68, respectively, and for the 2D + 3D set 0.62 and 0.65, respectively. Inter-rater agreement (Reader 1 vs. Reader 2) on EPE using Cohen's kappa for the 2D and 2D + 3D set, respectively, was 0.42 and 0.17 (i.e. moderate and poor agreement, respectively). Conclusion: The addition of 3D T2W MRI with radial reconstructions did not improve local staging in prostate cancer. PMID- 29456871 TI - GestationaL Obesity Weight management: Implementation of National Guidelines (GLOWING): a pilot cluster randomised controlled trial of a guideline implementation intervention for the management of maternal obesity by midwives. AB - Background: Weight management in pregnancy guidelines exist, although dissemination alone is an ineffective means of implementation. Midwives identify the need for support to overcome complex barriers to practice. An evaluation of an intervention to support midwives' guideline implementation would require a large-scale cluster randomised controlled trial. A pilot study is necessary to explore the feasibility of delivery and evaluation prior to a definitive trial. The GestationaL Obesity Weight management: Implementation of National Guidelines (GLOWING) trial aims to test whether it is feasible and acceptable to deliver a behaviour change intervention to support midwives' implementation of weight management guidelines. Methods: GLOWING is a multi-centre parallel group pilot cluster randomised controlled trial comparing the delivery of a behaviour change intervention for midwives versus usual practice. Four NHS Trusts (clusters) will be randomised to intervention and control arms, stratified by size of maternity services. The intervention uses social cognitive theory and consists of face-to face midwifery training plus information resources for routine practice. The main outcomes are whether the intervention and trial procedures are feasible and acceptable to participants and the feasibility of recruitment and data collection for a definitive trial. Target recruitment involves all eligible midwives in the intervention arm recruited to receive the intervention, 30 midwives and pregnant women per arm for baseline and outcome questionnaire data collection and 20 midwives and women to provide qualitative data. All quantitative and qualitative analyses will be descriptive with the purpose of informing the development of the definitive trial. Discussion: This pilot study has been developed to support community midwives' implementation of guidelines. Community midwives have been selected as they usually carry out the booking appointment which includes measuring and discussing maternal body mass index. A cluster design is the gold standard in implementation research as there would be a high risk of contamination if randomisation was at individual midwife level: community midwives usually work in locality-based teams, interact on a daily basis, and share care of pregnant women. The results of the pilot trial will be used to further develop and refine GLOWING prior to a definitive trial to evaluate effectiveness and cost-effectiveness.

AB - Introduction and Methods: The Rockefeller Clinical Scholars (KL2) Program began in 1976 and transitioned into a 3-year Master's degree program in 2006 when Rockefeller joined the NIH Clinical and Translational Science Award (CTSA) program. The program consists of ~15 trainees supported by the CTSA KL2 award and University funds. It is designed to provide an optimal environment for junior translational investigators to develop team science and leadership skills by designing and performing a human subjects protocol under the supervision of a distinguished senior investigator mentor and a team of content expert educators. This is complemented by a tutorial focused on important translational skills. Results: Since 2006, 40 Clinical Scholars have graduated from the programs and gone on to careers in academia (72%), government service (5%), industry (15%), and private medical practice (3%); two (5%) remain in training programs. 39/40 remain in translational research careers with 23 NIH awards totaling $23 million, foundation and philanthropic support of $20.3 million, and foreign government and foundation support of $6 million. They have made wide ranging scientific discoveries and have endeavored to translate those discoveries into improved human health. Conclusion: The Rockefeller Clinical Scholars (KL2) program provides one model for translational science training.

AB - The present article describes how to use the computer program BLEND to help assemble complete datasets for the solution of macromolecular structures, starting from partial or complete datasets, derived from data collection from multiple crystals. The program is demonstrated on more than two hundred X-ray diffraction datasets obtained from 50 crystals of a complex formed between the SRF transcription factor, its cognate DNA, and a peptide from the SRF cofactor MRTF-A. This structure is currently in the process of being fully solved. While full details of the structure are not yet available, the repeated application of BLEND on data from this structure, as they have become available, has made it possible to produce electron density maps clear enough to visualise the potential location of MRTF sequences.

AB - Foreign body ingestion occurs in not only children but also adults, particularly those with history of neurologic disease, alcohol use, or psychiatric disease. We present the case of a 40-year-old male with schizophrenia who presented to the emergency room with a long history of pharyngeal foreign body sensation which had recently progressed to include trismus, odynophagia, and dyspnea. Flexible laryngoscopy demonstrated fullness of the right posterior pharyngeal wall and computed tomography (CT) showed a linear opaque foreign body extending from the level of the oropharynx to the thyroid ala. Further history elicited that he stabbed himself in the pharynx two years prior with a toothbrush following a command hallucination. The toothbrush was removed uneventfully via an external approach. The patient was discharged with psychiatry follow-up. This case is unusual due to the submucosal location of the foreign body and the length of retention. It demonstrates the atypical nature which patients with comorbid psychiatric illness may present following foreign body injury and the use of an external surgical approach for the removal of a retained foreign body based on CT reconstruction. PMID- 29456876 TI - Cobalt-Catalyzed Stereoretentive Hydrogen Isotope Exchange of C(sp3)-H Bonds. AB - Cobalt dialkyl complexes bearing alpha-diimine ligands proved to be active precatalysts for the nondirected, C(sp3)-H selective hydrogen isotope exchange (HIE) of alkylarenes using D2 gas as the deuterium source. Alkylarenes with a variety of substitution patterns and heteroatom substituents on the arene ring were successfully labeled, enabling high levels of incorporation into primary, secondary, and tertiary benzylic C(sp3)-H bonds. In some cases, the HIE proceeded with high diastereoselectivity and application of the cobalt-catalyzed method to enantioenriched substrates with benzylic stereocenters provided enantioretentive hydrogen isotope exchange at tertiary carbons. PMID- 29456877 TI - A dextran-based probe for the targeted magnetic resonance imaging of tumours expressing prostate-specific membrane antigen. AB - Safe imaging agents able to render the expression and distribution of cancer receptors, enzymes or other biomarkers would facilitate clinical screening of the disease. Here, we show that diamagnetic dextran particles coordinated to a urea based targeting ligand for prostate-specific membrane antigen (PSMA) enable targeted magnetic resonance imaging (MRI) of the PSMA receptor. In a xenograft model of prostate cancer, micromolar concentrations of the dextran -ligand probe provided sufficient signal to specifically detect PSMA-expressing tumours via chemical exchange saturation transfer MRI. The dextran-based probe could be detected via the contrast originating from dextran hydroxyl protons, thereby avoiding the need of chemical substitution for radioactive or metallic labelling. Because dextrans are currently used clinically, dextran-based contrast agents may help extend receptor-targeted imaging to clinical MRI. PMID- 29456878 TI - Non-destructive two-photon excited fluorescence imaging identifies early nodules in calcific aortic-valve disease. AB - Calcifications occur during the development of healthy bone, and at the onset of calcific aortic-valve disease (CAVD) and many other pathologies. Although the mechanisms regulating early calcium deposition are not fully understood, they may provide targets for new treatments and for early interventions. Here, we show that two-photon excited fluorescence (TPEF) can provide quantitative and sensitive readouts of calcific nodule formation, in particular in the context of CAVD. Specifically, by means of the decomposition of TPEF spectral images from excised human CAVD valves and from rat bone prior to and following demineralization, as well as from calcific nodules formed within engineered gels, we identified an endogenous fluorophore that correlates with the level of mineralization in the samples. We then developed a ratiometric imaging approach that provides a quantitative readout of the presence of mineral deposits in early calcifications. TPEF should enable non-destructive, high-resolution imaging of three-dimensional tissue specimens for the assessment of the presence of calcification. PMID- 29456880 TI - Cost-effectiveness of nivolumab in patients with advanced renal cell carcinoma treated in the United States. AB - Background: We evaluated the cost-effectiveness of nivolumab versus everolimus in patients with advanced renal cell carcinoma (RCC) from a US payer perspective. Methods: A partitioned survival model consisting of three health states, progression-free survival (PFS), progressive disease, and death, was developed to evaluate the cost-effectiveness of intravenous nivolumab versus oral everolimus over a lifetime. The proportion of patients in each state was calculated based on parametric distributions fitted to PFS and overall survival (OS) data from CheckMate 025 (N = 821), a large randomized phase 3 trial of nivolumab versus everolimus for advanced RCC. Health state utility data were derived from CheckMate 025 EQ-5D data. Scenario analyses and deterministic and probabilistic sensitivity analyses assessed the impact of uncertainty in model inputs on outcomes. Results: Over a 25-year lifetime horizon, treatment with nivolumab resulted in a gain of 0.64 quality-adjusted life-years (QALYs) versus everolimus. Nivolumab had greater total costs versus everolimus ($US197,089 vs. $US163,902), mainly due to higher acquisition costs. The incremental cost-utility ratio (ICUR), a measure of incremental costs divided by incremental QALYs, was $US51,714 per QALY gained for nivolumab versus everolimus, and an incremental cost-effectiveness ratio was $US44,576 per life-year gained for nivolumab versus everolimus. In sensitivity analyses, average body weight had the greatest impact on the ICUR for nivolumab versus everolimus (base case $US51,714; range $US8863 $US94,566). At a $US150,000 willingness-to-pay (WTP) threshold, nivolumab had a 91.7% probability of being cost-effective versus everolimus. Conclusions: In the United States, at a WTP threshold of $US150,000 per QALY, nivolumab was found to be cost-effective. Key drivers of cost-effectiveness were survival inputs for OS and the average weight of patients; the latter directly affects nivolumab drug acquisition cost. PMID- 29456879 TI - Subcortical Effects on Voice and Fluency in Dysarthria: Observations from Subthalamic Nucleus Stimulation. AB - Objective: Parkinson's disease (PD), caused by basal ganglia dysfunction, is associated with motor disturbances including dysarthria. Stimulation of the subthalamic nucleus, a preferred treatment targeting basal ganglia function, improves features of the motor disorder, but has uncertain effects on speech.We studied speech during contrasting stimulation states to reveal subcortical effects on voice and articulation. Measures were made on selected samples of spontaneous and repeated speech. Methods: Persons with Parkinson's disease (PWP) who had undergone bilateral deep brain stimulation of the subthalamic nucleus (DBS-STN) provided spontaneous speech samples and then repeated portions of their monologue both on and off stimulation. Excerpts were presented in a listening protocol probing intelligibility. Also analysed were a continuous phrase repetition task and a second spontaneous speech sample. Fundamental frequency (F0), harmonic-to-noise ratio (HNR), jitter, shimmer and fluency were measured in these three speech samples performed with DBS stimulation on and off. Results: During subcortical stimulation, spontaneous excerpts were less intelligible than repeated excerpts. F0 and HNR were higher and shimmer was decreased in repetition and stimulation. Articulatory dysfluencies were increased for spontaneous speech and during stimulation in all three speech samples. Conclusion: Deep brain stimulation disrupts fluency and improves voice in spontaneous speech, reflecting an inverse influence of subcortical systems on articulatory posturing and laryngeal mechanisms. Better voice and less dysfluency in repetition may occur because an external model reduces the speech planning burden, as seen for gait and arm reach. These orthogonal results for fluency versus phonatory competence may account for ambivalent reports from dysarthric speakers and reveal the complexity of subcortical control of motor speech. PMID- 29456882 TI - Effects of osmolytes and macromolecular crowders on stable GAAA tetraloops and their preference for a CG closing base pair. AB - Osmolytes and macromolecular crowders have the potential to influence the stability of secondary structure motifs and alter preferences for conserved nucleic acid sequences in vivo. To further understand the cellular function of RNA we observed the effects of a model osmolyte, polyethylene glycol (PEG) 200, and a model macromolecular crowding agent, PEG 8000, on the GAAA tetraloop motif. GAAA tetraloops are conserved, stable tetraloops, and are critical participants in RNA tertiary structure. They also have a thermodynamic preference for a CG closing base pair. The thermal denaturation of model hairpins containing GAAA loops was monitored using UV-Vis spectroscopy in the presence and absence of PEG 200 or PEG 8000. Both of the cosolutes tested influenced the thermodynamic preference for a CG base pair by destabilizing the loop with a CG closing base pair relative to the loop with a GC closing base pair. This result also extended to a related DNA triloop, which provides further evidence that the interactions between the loop and closing base pair are identical for the d(GCA) triloop and the GAAA tetraloop. Our results suggest that in the presence of model PEG molecules, loops with a GC closing base pair may retain some preferential interactions with the cosolutes that are lost in the presence of the CG closing base pair. These results reveal that relatively small structural changes could influence how neutral cosolutes tune the stability and function of secondary structure motifs in vivo. PMID- 29456883 TI - Estimating common dolphin bycatch in the pole-and-line tuna fishery in the Azores. AB - Small-scale artisanal fisheries can have a significant negative impact in cetacean populations. Cetacean bycatch has been documented in the pole-and-line tuna fishery in the Azores with common dolphins being the species more frequently taken. Based on data collected by observers on ~50% of vessels operating from 1998 to 2012, we investigate the influence of various environmental and fisheries related factors in common dolphin bycatch and calculate fleet-wide estimates of total bycatch using design-based and model-based methods. Over the 15-year study dolphin bycatch occurred in less than 0.4% of the observed fishing events. Generalized additive modelling results suggest a significant relationship between common dolphin bycatch and duration of fishing events, sea surface temperature and location. Total bycatch calculated from the traditional stratified ratio estimation approach was 196 (95% CI: 186-205), while the negative binomial GAM estimated 262 (95% CI: 249-274) dolphins. Bycatch estimates of common dolphin were similar using statistical approaches suggesting that either of these methods may be used in future bycatch assessments for this fishery. Our work shows that rates of common dolphin bycatch in the pole-and-line tuna fishery in the Azores are low, despite considerable variations between years. Dolphins caught were released alive although the fate of these individuals is unknown. Continued monitoring will provide a better understanding of dolphin bycatch and more accurate estimates essential in the development of potential mitigation measures. PMID- 29456881 TI - Multimodality Treatment of Advanced Non-small Cell Lung Cancer: Where are we with the Evidence? AB - Purpose of review: The majority of patients with non-small cell lung cancer (NSCLC) present with advanced disease and overall survival rates are poor. This article outlines the current and outstanding evidence for the use of multimodality treatment in this group of patients, including in combination with an increasing number of treatment options, such as immunotherapy and genotype targeted small molecule inhibitors. Recent findings: Optimal therapy for surgically resectable stage III disease remains debatable and currently the choice of treatment reflects each individual patient's disease characteristics and the expertise and opinion of the thoracic multi-disciplinary team. Evidence for a distinct oligometastatic state in which improved outcomes can be achieved remains minimal and there is as yet no consensus definition for oligometastatic lung cancer. Whilst there is supporting evidence for the aggressive management of isolated metastases, the use of consolidative therapy for multiple metastases remains unproven. Summary: Evolution of new RT technologies, improved surgical technique and a plethora of interventional-radiology-guided ablative therapies are widening the choice of available treatment modalities to patients with NSCLC. In the setting of resectable locally advanced disease and the oligometastatic state, there is a growing need for randomised comparison of the available treatment modalities to guide both treatment and patient selection. PMID- 29456884 TI - Desiccation resistance: effect of cuticular hydrocarbons and water content in Drosophila melanogaster adults. AB - Background: The insect cuticle covers the whole body and all appendages and has bi-directionnal selective permeability: it protects against environmental stress and pathogen infection and also helps to reduce water loss. The adult cuticle is often associated with a superficial layer of fatty acid-derived molecules such as waxes and long chain hydrocarbons that prevent rapid dehydration. The waterproofing properties of cuticular hydrocarbons (CHs) depend on their chain length and desaturation number. Drosophila CH biosynthesis involves an enzymatic pathway including several elongase and desaturase enzymes. Methods: The link between desiccation resistance and CH profile remains unclear, so we tested (1) experimentally selected desiccation-resistant lines, (2) transgenic flies with altered desaturase expression and (3) natural and laboratory-induced CH variants. We also explored the possible relationship between desiccation resistance, relative water content and fecundity in females. Results: We found that increased desiccation resistance is linked with the increased proportion of desaturated CHs, but not with their total amount. Experimentally-induced desiccation resistance and CH variation both remained stable after many generations without selection. Conversely, flies with a higher water content and a lower proportion of desaturated CHs showed reduced desiccation resistance. This was also the case in flies with defective desaturase expression in the fat body. Discussion: We conclude that rapidly acquired desiccation resistance, depending on both CH profile and water content, can remain stable without selection in a humid environment. These three phenotypes, which might be expected to show a simple relationship, turn out to have complex physiological and genetic links.

AB - Comprising more than 800 extant species, the class Cephalopoda (octopuses, squid, cuttlefish, and nautiluses) is a fascinating group of marine conchiferan mollusks. Recently, the first cephalopod genome (of Octopus bimaculoides) was published, providing a genomic framework, which will enable more detailed investigations of cephalopod characteristics, including developmental, morphological, and behavioural traits. Meanwhile, a robust phylogeny of the members of the subclass Coleoidea (octopuses, squid, cuttlefishes) is crucial for comparative and evolutionary studies aiming to investigate the group's traits and innovations, but such a phylogeny has proven very challenging to obtain. Here, we present the results of phylogenetic inference at the genus level using mitochondrial and nuclear marker sequences available from public databases. Topologies are presented which show support for (1) the monophyly of the two main superorders, Octobrachia and Decabrachia, and (2) some of the interrelationships at the family level. We have mapped morphological characters onto the tree and conducted molecular dating analyses, obtaining congruent results with previous estimates of divergence in major lineages. Our study also identifies unresolved phylogenetic relationships within the cephalopod phylogeny and insufficient taxonomic sampling among squids excluding the Loliginidae in the Decabrachia and within the Order Cirromorphida in the Octobrachia. Genomic and transcriptomic resources should enable resolution of these issues in the relatively near future. We provide our alignment as an open access resource, to allow other researchers to reconstruct phylogenetic trees upon this work in the future.

AB - Liver fibrosis is a disease that causes high morbidity and has become a major health problem. Liver fibrosis can lead to the end stage of liver diseases (livercirrhosisand hepatocellularcarcinoma). Currently, liver transplantation is the only effective treatment for end-stage liver disease. However, the shortage of organ donors, high cost of medical surgery, immunological rejection and transplantation complications severely hamper liver transplantation therapy. Mesenchymal stem cells (MSCs) have been regarded as promising cells for clinical applications in stem cell therapy in the treatment of liver diseases due to their unique multipotent differentiation capacity, immunoregulation and paracrine effects. Although liver fibrosis improvements by MSC transplantation in preclinical experiments as well as clinical trials have been reported, the in vivo fate of MSCs after transportation and their therapeutic mechanisms remain unclear. In this present study, we isolated MSCs from the bone marrow of rhesus macaques. The cells exhibited typical MSC markers and could differentiate into chondrocytes, osteocytes, and adipocytes, which were not affected by labeling with enhanced green fluorescent protein (EGFP). The harvested MSCs respond to interferon-gamma stimulation and have the ability to inhibit lymphocyte proliferation in vitro. EGFP-labeled MSCs (1 * 106 cells) were transplanted into mice with carbon tetrachloride-induced liver fibrosis via tail vein injection. The ability of the heterogenic MSC infusion to ameliorate liver fibrosis in mice was evaluated by a blood plasma chemistry index, pathological examination and liver fibrosis-associated gene expression. Additionally, a small number of MSCs that homed and engrafted in the mouse liver tissues were evaluated by immunofluorescence analysis. Our results showed that the transplantation of heterogenic MSCs derived from monkey bone marrow can be used to treat liver fibrosis in the mouse model and that the paracrine effects of MSCs may play an important role in the improvement of liver fibrosis.

AB - Trachemys (Testudines: Emydidae) represents one of the most well-known turtle genera today. The evolution of Trachemys, while being heavily documented with fossil representatives, is not well understood. Numerous fossils from the late Hemphillian Gray Fossil Site (GFS) in northeastern Tennessee help to elucidate its evolution. The fossil Trachemys at the GFS represent a new species. The new taxon, Trachemys haugrudi, is described, and currently represents the most thoroughly described fossil emydid species known. A phylogenetic analysis, including 31 species, focusing on the subfamily Deirochelyinae is performed that includes the new fossil species, along with numerous other modern and fossil deirochelyine species, representing the first phylogenetic analysis published that includes several fossil deirochelyines. The phylogenetic analysis, utilizing morphological evidence, provides monophyletic clades of all modern deirochelyines, including Chrysemys, Deirochelys, Pseudemys, Malaclemys, Graptemys, and Trachemys. A strict consensus tree finds the recently described fossil species Graptemys kerneri to be part of a clade of Graptemys + Malaclemys. Three fossil taxa, including one previously referred to Pseudemys (Pseudemys caelata) and two to Deirochelys (Deirochelys carri and Deirochelys floridana) are found to form a clade with modern Deirochelys reticularia reticularia, with D. floridana sister to the other members of the clade. Chrysemys is found to be part of a basal polytomy with Deirochelys in relation to other deirochelyine taxa. Two fossil taxa previously referred to Chrysemys (Chrysemys timida and Chrysemys williamsi) form a paraphyly with the modern Chrysemys picta picta and Deirochelys, and may be referable to distinct genera. Additionally, fossil taxa previously attributed to Trachemys (Trachemys hillii, Trachemys idahoensis, Trachemys inflata, and Trachemys platymarginata) and T. haugrudi are found to form a clade separate from clades of northern and southern Trachemys species, potentially suggesting a distinct lineage of Trachemys with no modern survivors. Hypotheses of phylogenetic relationships mostly agree between the present study and previous ones, although the inclusion of fossil taxa provides further clues to the evolution of parts of the Deirochelyinae. The inclusion of more fossil taxa and characters may help resolve the placement of some taxa, and further elucidate the evolution of these New World turtles.

AB - Introduction: The treatment with tyrosine kinase inhibitors (TKIs) has drastically improved the outcome of chronic myeloid leukemia (CML) patients. This study was conducted to examine the risk of secondary cancers (SCs) in the CML patients who were diagnosed and treated in the TKI era in the United States. Methods: The surveillance epidemiology and end results (SEER) database was used to identify CML patients who were diagnosed and received treatment during January 2002-December 2014. Standardized incidence ratios (SIRs) and absolute excess risks (AER) were calculated. Results: Overall, 511 SCs (excluding acute leukemia) developed in 9,200 CML patients followed for 38,433 person-years. The risk of developing SCs in the CML patients was 30% higher than the age, sex and race matched standard population (SIR 1.30, 95% CI: 1.2-1.40; p < 0.001). The SIRs for CLL (SIR 3.4, 95% CI: 2-5.5; p < 0.001), thyroid (SIR 2.2, 95% CI: 1.2-3.5; p < 0.001), small intestine (SIR 3.1, 95% CI: 1.1-7; p = 0.004), gingiva (SIR 3.7, 95% CI: 1.2-8.7; p = 0.002), stomach (SIR 2.1, 95% CI: 1.1-3.5; p = 0.005), lung (SIR 1.4, 95% CI: 1.1-1.7; p = 0.006) and prostate (SIR 1.3, 95% CI: 1.02-1.6; p = 0.026) cancer among CML patients were significantly higher than the general population. The risk of SCs was higher irrespective of age and it was highest in the period 2-12 months after the diagnosis of CML. The risk of SCs in women was similar to that of the general population. Conclusion: CML patients diagnosed and treated in the TKI era in the United States are at an increased risk of developing a second malignancy. The increased risk of SCs in the early period after CML diagnosis suggests that the risk of SCs may be increased due to the factors other than TKIs treatment. PMID- 29456890 TI - A six-year grazing exclusion changed plant species diversity of a Stipa breviflora desert steppe community, northern China. AB - Excluding grazers is one of most efficient ways to restore degraded grasslands in desert-steppe communities, but may negatively affect the recovery of plant species diversity. However, diversity differences between grazed and fenced grasslands in desert-steppe are poorly known. In a Stipa breviflora desert steppe community in Northern China, we established six plots to examine spatial patterns of plant species diversity under grazed and fenced conditions, respectively. We addressed three aspects of species diversity: (1) The logistic, exponential and power models were used to describe the species-area curve (SAR). Species richness, abundance and Shannon diversity values change differently with increasing sampling areas inside and outside of the fence. The best fitted model for SAR was the logistic model. Excluding grazers had a significant impact on the shape of SAR. (2) Variograms was applied to examine the spatial characteristics of plant species diversity. We found strong spatial autocorrelations in the diversity variables both inside and outside the fence. After grazing exclusion, the spatial heterogeneity decreased in species richness, increased in abundance and did not change in Shannon diversity. (3) We used variance partitioning to determine the relative contributions of spatial and environmental factors to plant species diversity patterns. Environmental factors explained the largest proportion of variation in species diversity, while spatial factors contributed little. Our results suggest that grazing enclosures decreased species diversity patterns and the spatial pattern of the S. breviflora desert steppe community was predictable. PMID- 29456889 TI - A bibliometric analysis in gene research of myocardial infarction from 2001 to 2015. AB - Objectives: We aimed to evaluate the global scientific output of gene research of myocardial infarction and explore their hotspots and frontiers from 2001 to 2015, using bibliometric methods. Methods: Articles about the gene research of myocardial infarction between 2001 and 2015 were retrieved from the Web of Science Core Collection (WoSCC). We used the bibliometric method and Citespace V to analyze publication years, journals, countries, institutions, research areas, authors, research hotspots, and trends. We plotted the reference co-citation network, and we used key words to analyze the research hotspots and trends. Results: We identified 1,853 publications on gene research of myocardial research from 2001 to 2015, and the annual publication number increased with time. Circulation published the highest number of articles. United States ranked highest in the countries with most publications, and the leading institute was Harvard University. Relevant publications were mainly in the field of Cardiovascular system cardiology. Keywords and references analysis indicated that gene expression, microRNA and young women were the research hotspots, whereas stem cell, chemokine, inflammation and cardiac repair were the frontiers. Conclusions: We depicted gene research of myocardial infarction overall by bibliometric analysis. Mesenchymal stem cells Therapy, MSCs-derived microRNA and genetic modified MSCs are the latest research frontiers. Related studies may pioneer the future direction of this filed in next few years. Further studies are needed. PMID- 29456891 TI - Frequency and developmental timing of linear enamel hypoplasia defects in Early Archaic Texan hunter-gatherers. AB - Digital photographs taken under controlled conditions were used to examine the incidence of linear enamel hypoplasia defects (LEHs) in burials from the Buckeye Knoll archaeological site (41VT98 Victoria county, Texas), which spans the Early to Late Archaic Period (ca. 2,500-6,500 BP uncorrected radiocarbon). The majority (68 of 74 burials) date to the Texas Early Archaic, including one extremely early burial dated to 8,500 BP. The photogrammetric data collection method also results in an archive for Buckeye Knoll, a significant rare Archaic period collection that has been repatriated and reinterred. We analyzed the incidence and developmental timing of LEHs in permanent canines. Fifty-nine percent of permanent canines (n = 54) had at least one defect. There were no significant differences in LEH frequency between the maxillary and mandibular canines (U = 640.5, n1 = 37, n2 = 43, p = .110). The sample studied (n = 92 permanent canines) had an overall mean of 0.93 LEH defect per tooth, with a median of one defect, and a mode of zero defects. Average age at first insult was 3.92 (median = 4.00, range = 2.5-5.4) and the mean age of all insults per individual was 4.18 years old (range = 2.5-5.67). Age at first insult is consistent with onset of weaning stress-the weaning age range for hunter-gatherer societies is 1-4.5. Having an earlier age of first insult was associated with having more LEHs (n = 54, rho = 0.381, p = 0.005). PMID- 29456892 TI - Under the armor: X-ray computed tomographic reconstruction of the internal skeleton of Coahomasuchus chathamensis (Archosauria: Aetosauria) from the Upper Triassic of North Carolina, USA, and a phylogenetic analysis of Aetosauria. AB - Aetosauria is a clade of heavily armored, quadrupedal omnivorous to herbivorous archosaurs known from the Late Triassic across what was the supercontinent of Pangea. Their abundance in many deposits relative to the paucity of other Triassic herbivores indicates that they were key components of Late Triassic ecosystems. However, their evolutionary relationships remain contentious due, in large part, to their extensive dermal armor, which often obstructs observation of internal skeletal anatomy and limits access to potentially informative characters. In an attempt to address this problem we reanalyzed the holotype of a recently described species of Coahomasuchus, C. chathamensis, from the Sanford sub-basin of North Carolina using computed tomography (CT). CT scans of the holotype specimen clarify preservation of the skeleton, revealing several articulated vertebrae and ribs, an isolated vertebra, left ulna, left scapula, and the right humerus, though none of the material resulted in updated phylogenetic scorings. Reexamination of aetosaur materials from the holotype locality also indicates that several isolated osteoderms and elements of the appendicular skeleton are newly referable. Based on these results, we update the Coahomasuchus chathamensis hypodigm and conduct a revised phylogenetic analysis with improved character scorings for Coahomasuchus and several other aetosaurs. Our study recovers Coahomasuchus in a polytomy with Aetosaurus and the Typothoracinae, in contrast with a recent analysis that recovered Coahomasuchus as a wild-card taxon. PMID- 29456893 TI - The effect of supragingival glycine air polishing on periodontitis during maintenance therapy: a randomized controlled trial. AB - Background: Glycine air polishing has been proved to be safe, comfortable and time-saving. Whether it could substitute ultrasonic scaling to remove dental plaque biofilm during periodontal maintenance remains unclear. The purposes of this study were to evaluate the effect of supragingival glycine air polishing (SGAP) on the subgingival periodontal pathogens during maintenance therapy and to check the association of periodontal pathogens and clinical parameters. Methods: Twenty-three chronic periodontitis patients during their maintenance therapy were enrolled in the 12-week study. According to randomized split-mouth design, the test side was treated with SGAP (65 MUm), while the control side was treated with supragingival ultrasonic scaling and polishing (SUSP) with rubber cup. Clinical examination including plaque index (PLI), probing depth (PD), bleeding index (BI) were performed at baseline and 12 weeks post-treatment. Sampling of the subgingival plaque at each investigational site (mesiobuccal site of the mandibular first molar) was performed at baseline and 2, 4, 8, 12 weeks after maintenance treatment. Four periodontal pathogens including Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola and Fusobacterium nucleatum were detected by 16S rDNA polymerase chain reaction. Results: Clinical status generally improved after treatment in both groups. PLI in both groups, PD in SGAP group and bleeding on probing (%) in SUSP group significantly decreased after treatment (p < 0.05). There was no significant difference of clinical parameters between two groups before and after treatment. The detection rates of P. gingivalis, T. denticola in both groups, T. forsythia in SUSP group and F. nucleatum in SGAP group decreased after maintenance treatment in both groups, although no significant difference was found, and it rebound to baseline level at 12 weeks after maintenance treatment. There was no significant difference between SGAP group and SUSP group at any time point. T. denticola-positive sites had significantly greater BI than T. denticola-negative sites (p < 0.05). Discussion: Supragingival glycine air polishing had a reliable effect in removing subgingival dental plaque biofilm during maintenance period, and three months may be a proper maintenance interval for pockets not more than 5 mm. PMID- 29456894 TI - The state of OA: a large-scale analysis of the prevalence and impact of Open Access articles. AB - Despite growing interest in Open Access (OA) to scholarly literature, there is an unmet need for large-scale, up-to-date, and reproducible studies assessing the prevalence and characteristics of OA. We address this need using oaDOI, an open online service that determines OA status for 67 million articles. We use three samples, each of 100,000 articles, to investigate OA in three populations: (1) all journal articles assigned a Crossref DOI, (2) recent journal articles indexed in Web of Science, and (3) articles viewed by users of Unpaywall, an open-source browser extension that lets users find OA articles using oaDOI. We estimate that at least 28% of the scholarly literature is OA (19M in total) and that this proportion is growing, driven particularly by growth in Gold and Hybrid. The most recent year analyzed (2015) also has the highest percentage of OA (45%). Because of this growth, and the fact that readers disproportionately access newer articles, we find that Unpaywall users encounter OA quite frequently: 47% of articles they view are OA. Notably, the most common mechanism for OA is not Gold, Green, or Hybrid OA, but rather an under-discussed category we dub Bronze: articles made free-to-read on the publisher website, without an explicit Open license. We also examine the citation impact of OA articles, corroborating the so called open-access citation advantage: accounting for age and discipline, OA articles receive 18% more citations than average, an effect driven primarily by Green and Hybrid OA. We encourage further research using the free oaDOI service, as a way to inform OA policy and practice. PMID- 29456895 TI - Calibration adjustments to address bias in mortality analyses due to informative sampling-a census-linked survey analysis in Switzerland. AB - Background: Sampling bias, like survey participants' nonresponse, needs to be adequately addressed in the analysis of sampling designs. Often survey weights will be calibrated on specific covariates related to the probability of selection and nonresponse to get representative population estimates. However, such calibrated survey (CS) weights are usually constructed for cross-sectional results, but not for longitudinal analyses. For example, when the outcome of interest is time to death, and sampling selection is related to time to death and censoring, sampling is informative. Then, unweighted or CS weighted inferential statistical analyses may be biased. In 2010, Switzerland changed from a decennial full enumeration census to a yearly registry-based (i.e., data from harmonised community registries) and a survey-based census system. In the present study, we investigated the potential bias due to informative sampling when time to death is the outcome of interest, using data from the new Swiss census system. Methods: We analysed more than 6.5 million individuals aged 15 years or older from registry based census data from years 2010 to 2013, linked with mortality records up to end of 2014. Out of this population, a target sample of 3.5% was sampled from the Swiss Federal Statistical Office (SFSO) in a stratified yearly micro census. The SFSO calculated CS weights to enable representative population estimates from the micro census. We additionally constructed inverse probability (IP) weights, where we used survival information in addition to known sampling covariates. We compared CS and IP weighted mortality rates (MR) and life expectancy (LE) with estimates from the underlying population. Additionally, we performed a simulation study under different sampling and nonresponse scenarios. Results: We found that individuals who died in 2011, had a 0.67 (95% CI [0.64-0.70]) times lower odds of participating in the 2010 micro census, using a multivariable logistic regression model with covariates age, gender, nationality, civil status, region and survival information. IP weighted MR were comparable to estimates from the total population, whereas CS weighted MR underestimated the population MR in general. The IP weighted LE estimates at age 30 years for men were 50.9 years (95% CI [50.2-51.6] years), whereas the CS weighted overestimated LE by 2.5 years. Our results from the simulation study confirmed that IP weighted models are comparable to population estimates. Conclusion: Mortality analyses based on the new Swiss survey-based census system may be biased, because of informative sampling. We conclude that mortality analyses based on census-linked survey data have to be carefully conducted, and if possible, validated by registry information to allow for unbiased interpretation and generalisation. PMID- 29456897 TI - Detection of Essential Tremor at the [Formula: see text]-Band. AB - Essential tremor (ET) is a neurological disorder characterized by rhythmic, involuntary shaking of a part or parts of the body. The most common tremor is seen in the hands/arms and fingers. This paper presents an evaluation of ETs monitoring based on finger-to-nose test measurement as captured by small wireless devices working in shortwave or [Formula: see text]-band frequency range. The acquired signals in terms of amplitude and phase information are used to detect a tremor in the hands. Linearly transforming raw phase data acquired in the [Formula: see text]-band were carried out for calibrating the phase information and to improve accuracy. The data samples are used for classification using support vector machine algorithm. This model is used to differentiate the tremor and nontremor data efficiently based on secondary features that characterize ET. The accuracy of our measurements maintains linearity, and more than 90% accuracy rate is achieved between the feature set and data samples. PMID- 29456896 TI - Factors associated with elevated blood pressure or hypertension in Afro-Caribbean youth: a cross-sectional study. AB - Background: Although several studies have identified risk factors for high blood pressure (BP), data from Afro-Caribbean populations are limited. Additionally, less is known about how putative risk factors operate in young adults and how social factors influence the risk of high BP. In this study, we estimated the relative risk for elevated BP or hypertension (EBP/HTN), defined as BP >= 120/80 mmHg, among young adults with putative cardiovascular disease (CVD) risk factors in Jamaica and evaluated whether relative risks differed by sex. Methods: Data from 898 young adults, 18-20 years old, were analysed. BP was measured with a mercury sphygmomanometer after participants had been seated for 5 min. Anthropometric measurements were obtained, and glucose, lipids and insulin measured from a fasting venous blood sample. Data on socioeconomic status (SES) were obtained via questionnaire. CVD risk factor status was defined using standard cut-points or the upper quintile of the distribution where the numbers meeting standard cut-points were small. Relative risks were estimated using odds ratios (OR) from logistic regression models. Results: Prevalence of EBP/HTN was 30% among males and 13% among females (p < 0.001 for sex difference). There was evidence for sex interaction in the relationship between EBP/HTN and some of risk factors (obesity and household possessions), therefore we report sex-specific analyses. In multivariable logistic regression models, factors independently associated with EBP/HTN among men were obesity (OR 8.48, 95% CI [2.64-27.2], p < 0.001), and high glucose (OR 2.01, CI [1.20-3.37], p = 0.008), while high HOMA-IR did not achieve statistical significance (OR 2.08, CI [0.94-4.58], p = 0.069). In similar models for women, high triglycerides (OR 1.98, CI [1.03-3.81], p = 0.040) and high HOMA-IR (OR 2.07, CI [1.03-4.12], p = 0.039) were positively associated with EBP/HTN. Lower SES was also associated with higher odds for EBP/HTN (OR 4.63, CI [1.31-16.4], p = 0.017, for moderate vs. high household possessions; OR 2.61, CI [0.70-9.77], p = 0.154 for low vs. high household possessions). Alcohol consumption was associated with lower odds of EBP/HTN among females only; OR 0.41 (CI [0.18-0.90], p = 0.026) for drinking <1 time per week vs. never drinkers, and OR 0.28 (CI [0.11-0.76], p = 0.012) for drinking >=3 times per week vs. never drinkers. Physical activity was inversely associated with EBP/HTN in both males and females. Conclusion: Factors associated with EBP/HTN among Jamaican young adults include obesity, high glucose, high triglycerides and high HOMA-IR, with some significant differences by sex. Among women lower SES was positively associated with EBP/HTN, while moderate alcohol consumption was associated lower odds of EBP/HTN. PMID- 29456898 TI - Passive Radar for Opportunistic Monitoring in E-Health Applications. AB - This paper proposes a passive Doppler radar as a non-contact sensing method to capture human body movements, recognize respiration, and physical activities in e Health applications. The system uses existing in-home wireless signal as the source to interpret human activity. This paper shows that passive radar is a novel solution for multiple healthcare applications which complements traditional smart home sensor systems. An innovative two-stage signal processing framework is outlined to enable the multi-purpose monitoring function. The first stage is to obtain premier Doppler information by using the high speed passive radar signal processing. The second stage is the functional signal processing including micro Doppler extraction for breathing detection and support vector machine classifier for physical activity recognition. The experimental results show that the proposed system provides adequate performance for both purposes, and prove that non-contact passive Doppler radar is a complementary technology to meet the challenges of future healthcare applications. PMID- 29456899 TI - Facial Weakness, Diplopia, and Fever in a 31-Year-Old: An Atypical Case of Tuberculous Meningitis. AB - Tuberculous meningitis (TBM) is an infection of the central nervous system (CNS) meninges that carries high morbidity and mortality. It is important to recognize, as patients may present with atypical symptoms. We describe the case of a 31-year old man with a history of diabetes who presented with a sub-acute onset of right sided facial weakness and right gaze difficulty with diplopia. History revealed low-grade fever, right-sided headache, fatigue and moderate weight loss for the past several weeks. The patient did not report neck stiffness, rigidity, fever, chills or cough. The physical exam revealed sixth nerve palsy with a right Horner's syndrome. Magnetic resonance imaging (MRI) of the brain showed pachymeningeal enhancement. A spinal tap revealed elevated white blood cells (WBCs), glucose and protein; cerebrospinal fluid (CSF) culture showed Mycobacterium tuberculosis. The patient was diagnosed with TBM and treated with isoniazid, rifampin, pyrazinamide, ethambutol and vitamin B6 for 12 months. The timely diagnosis of TBM can be challenging due to a nonspecific clinical presentation. In patients with a sub-acute onset of headache, fever and meningeal signs, TBM should be considered in the differential. If suspected, treatment should be initiated immediately to prevent further neurological impairment and death. PMID- 29456900 TI - A Barium Swallow Study Leading to an Incidental Finding on a Screening Colonoscopy. AB - Barolith is a mixture of firm feces with barium sulfate, and a frequent cause of obstruction of the appendiceal lumen that can result in appendicitis. Nonetheless, some other complications like aspiration, allergic reaction, and bowel obstruction have also been reported. We present the case of a 71-year-old man with a history of amyotrophic lateral sclerosis (ALS), who came to the gastroenterology clinic complaining of intermittent loose stools and dysphagia to solids for the past months. The patient underwent a barium swallow study six days prior and was completely normal. A colonoscopy was done showing normal appearing mucosa, with a whitish foreign object found on the appendiceal orifice. Removal of the barolith was done by means of a biopsy forceps. Our patient did not have any signs or symptoms of appendicitis prior to the procedure, and the successful removal of the barolith was achieved. Elderly patients, and patients with decreased gastrointestinal (GI) transit, could be a population at risk for barium retention/appendicitis; for this reason, more research studies should be done to assess possible preventive treatments. PMID- 29456901 TI - Awake Craniotomy for the Treatment of a Cortical Pseudoaneurysm in a Pregnant Patient. AB - Neurosurgical pathologies presenting during pregnancy are uncommon. If present, the situation creates a unique diagnostic, observational, and therapeutic challenge as both lives are placed at potential risk. Surgical procedures during pregnancy are approached carefully as physiological stressors associated with surgery and anesthesia may cause fetal or maternal compromise. We present the only known case of a pseudoaneurysm treated with an awake craniotomy, allowing us to abate the risks associated with general anesthesia in pregnancy. A female suffered a superficially penetrating gunshot wound to the head for which she underwent a craniotomy with complete neurological recovery. She had complaints of intermittent headaches, dizziness, and tingling of her hands five months thereafter. The cerebral angiogram demonstrated an 8 mm pseudoaneurysm under her craniotomy site. A surgical repair of this aneurysm was undertaken in the 23rd week of pregnancy via an awake craniotomy with regional scalp block. The aneurysm was resected without complication, and the patient tolerated the procedure without neurological deficit during or subsequent to the operation. Cerebrovascular pathology in pregnant patients remains a difficult situation that poses challenges associated with the pathology itself as well as the anesthetic implications inherent with operative management. The neurosurgical literature demonstrates that surgical management of cerebrovascular pathology is well tolerated in pregnancy, and our case further demonstrates the capability of utilizing an awake craniotomy for the treatment of this type of lesion without causing a residual deficit. PMID- 29456902 TI - Review of Assessment Scales for Diagnosing and Monitoring Sports-related Concussion. AB - Sports-related concussion has emerged as a public health crisis due to increased diagnosis of the condition and increased participation in organized and recreational athletics worldwide. Under-recognition of concussions can lead to premature clearance for athletic participation, leaving athletes vulnerable to repeat injury and subsequent short- and long-term complications. There is overwhelming evidence that assessment and management of sports-related concussions should involve a multifaceted approach. A number of assessment criteria have been developed for this purpose. It is important to understand the available and emerging diagnostic testing modalities for sports-related concussions. The most commonly used tools for evaluating individuals with concussion are the Post-Concussion Symptom Scale (PCSS), Standard Assessment of Concussion (SAC), Standard Concussion Assessment Tool (SCAT3), and the most recognized computerized neurocognitive test, the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT). The strengths and limitations of each of these tools, and the Concussion Resolution Index (CRI), CogSport, and King Devick tests were evaluated. Based on the data, it appears that the most sensitive and specific of these is the ImPACT test. Additionally, the King-Devick test is an effective adjunct due to its ability to test eye movements and brainstem function. PMID- 29456903 TI - Winged Scapula: A Comprehensive Review of Surgical Treatment. AB - Winged scapula is caused by paralysis of the serratus anterior or trapezius muscles due to damage to the long thoracic or accessory nerves, resulting in loss of strength and range of motion of the shoulder. Because this nerve damage can happen in a variety of ways, initial diagnosis may be overlooked. This paper discusses the anatomical structures involved in several variations of winged scapula, the pathogenesis of winged scapula, and several historical and contemporary surgical procedures used to treat this condition. Additionally, this review builds upon the conclusions of several studies in order to suggest areas for continued research regarding the treatment of winged scapula. PMID- 29456904 TI - Felis Punctatis: Cat Claw-induced Punctures. AB - Animal-induced conditions in humans predominantly present as infectious zoonoses. However, trauma-associated injuries from the teeth or claws can also occur. Several zoonotic infections can be transmitted by cats, a common household pet, to their owners. The clinical features of a woman who developed multiple sites of trauma-induced cutaneous punctures from her cat's paws while it was kneading on her clothes-covered abdomen are described. The repetitive insertion and withdrawal of the sharp tips of the cat's claws created distinctive groups of erythematous punctures on the patient's skin. We suggest that Latin nomenclature be used to designate the name for this claw-induced dermatosis that includes not only the causative animal (felis for cat) but also a descriptive term for the skin lesions (punctatis for punctures): felis punctatis. PMID- 29456905 TI - A Comprehensive Review of the Sternal Foramina and its Clinical Significance. AB - A sternal foramen (SF), which arises from the incomplete fusion of the cartilaginous neonatal sternum, is a relatively common anatomical variation found in 2.5% to 13.8 % of all individuals. SFs are usually located at the lower third of the sternal body and their average diameter is 6.5 mm. An SF is subclinical; however, its close proximity to the thoracic organs, i.e., the heart and lungs, entails a risk of serious complications from blinded sternal interventions. Moreover, its presence can lead to misinterpretation of radiological and postmortem findings. The SF is ignored by many physicians and non-physician healthcare providers who must understand its clinical significance in order to optimize patient care. Our aim in this review is to highlight the potential clinical consequences for SF patients, discuss recommendations for performing sternal procedures safely when this anatomical variation is present, and preclude radiological and pathological misinterpretations so that patient care can be improved. PMID- 29456906 TI - Health Communication Experiences of Emerging Adults with Type 1 Diabetes. AB - Objective: In an effort to refine a model of clinical care identifying effective communication with health care providers (HCPs) as a key skill for successful transition to adult medical care, this study explored the perspectives of emerging adults with type 1 diabetes (T1D) about factors that impact the quality and content of communication with their HCPs. Methods: Twenty emerging adults with T1D were interviewed about health communication experiences with their pediatric HCP and readiness for transition to adult diabetes care. Interviews were recorded and transcribed; three raters coded transcripts using conventional content analysis for broad themes. Results: Five themes emerged from the data capturing factors that influence emerging adult-HCP communication: HCP interaction style, HCP consistency, HCP support for autonomy, parental involvement in medical care, and emerging adult comfort with disclosure. Most emerging adults had not discussed transition to adult diabetes care with their HCP; some expressed confidence in their ability to transition while others expressed anxiety about the transition process. Conclusions: Findings support the conceptual model of communication and inform clinical implications for working with emerging adults with T1D. Continuity of care should be prioritized with transition-age patients. Additionally, HCPs should initiate conversations about engagement in risky behaviors and transition to adult medical care and ensure emerging adults have time without parents to discuss these sensitive topics. Psychologists can enhance the transition process by facilitating effective patient-HCP communication and coaching both patients and HCPs to ask questions about risky behaviors and transition to adult medical care.

AB - Study Design: Health utility analysis. Objectives: To determine the health state utility (HSU) of 1- and 2-level anterior cervical discectomy and fusion (ACDF) and cervical disc replacement (CDR). Methods: Data from the Medtronic Prestige Cervical Disc investigational device exemption studies was used. Four groups were defined: 1-level ACDF, 1-level CDR, 2-level ACDF, and 2-level CDR. The 36-item Short Form Health Survey (SF-36) was collected at baseline, 12 months, 24 months, 36 months, and 60 months postoperatively and converted into utility scores for each time point. A repeated-measures 1-way analysis of variance (ANOVA) was used to detect differences among groups. Tukey's method for multiple comparisons was used to determine which means within the groups were statistically different (P < .05). Results: We found a statistically significant difference in HSU among groups as determined by repeated-measures 1-way ANOVA (P = .0008). Post hoc analysis indicated that 1-level ACDF had a statistically lower utility score compared with 1- and 2-level CDR (P = .04 and P = .02, respectively). Similarly, 2-level ACDF had lower utility values compared with 2-level CDR (P = .010). One level ACDF utility values were not different from 2-level ACDF values (P = .55). Similarly, 1-level CDR and 2-level CDR did not have different utility values (P = .67). Conclusions: Overall, CDR had higher health state utility scores for 1- and 2-level procedures at every time point. This study indicates that CDR results in a higher postoperative health utility state than ACDF, and may therefore be an effective alternative to ACDF for treating degenerative conditions of the cervical spine. PMID- 29456907 TI - Nanoparticles in the environment: where do we come from, where do we go to? AB - Nanoparticles serve various industrial and domestic purposes which is reflected in their steadily increasing production volume. This economic success comes along with their presence in the environment and the risk of potentially adverse effects in natural systems. Over the last decade, substantial progress regarding the understanding of sources, fate, and effects of nanoparticles has been made. Predictions of environmental concentrations based on modelling approaches could recently be confirmed by measured concentrations in the field. Nonetheless, analytical techniques are, as covered elsewhere, still under development to more efficiently and reliably characterize and quantify nanoparticles, as well as to detect them in complex environmental matrixes. Simultaneously, the effects of nanoparticles on aquatic and terrestrial systems have received increasing attention. While the debate on the relevance of nanoparticle-released metal ions for their toxicity is still ongoing, it is a re-occurring phenomenon that inert nanoparticles are able to interact with biota through physical pathways such as biological surface coating. This among others interferes with the growth and behaviour of exposed organisms. Moreover, co-occurring contaminants interact with nanoparticles. There is multiple evidence suggesting nanoparticles as a sink for organic and inorganic co-contaminants. On the other hand, in the presence of nanoparticles, repeatedly an elevated effect on the test species induced by the co-contaminants has been reported. In this paper, we highlight recent achievements in the field of nano-ecotoxicology in both aquatic and terrestrial systems but also refer to substantial gaps that require further attention in the future. PMID- 29456910 TI - Comparing the Incidence of Index Level Fusion Following Minimally Invasive Versus Open Lumbar Microdiscectomy. AB - Study Design: Retrospective cohort study. Objectives: To determine the incidence of index level fusion following open or minimally invasive lumbar microdiscectomy. Methods: We conducted a retrospective review of 174 patients with a symptomatic single-level lumbar herniated nucleus pulposus who underwent microdiscectomy via a mini-open approach (MIS; 39) or through a minimally invasive dilator tube (135). Outcomes of interest included revision microdiscectomy and the ultimate need for index level fusion. Continuous variables were analyzed with independent sample t test, and chi2 analysis was used for categorical data. A multivariate regression analysis was performed to identify predictive factors for patients that required index level fusion after lumbar microdiscectomy. Results: There was no difference in patient demographics in the open and MIS groups aside from length of follow-up (60.4 vs 40.03 months, P < .0001) and body mass index (24.72 vs 27.21, P = .03). The rate of revision microdiscectomy was not statistically significant between open and MIS approaches (10.3% vs 10.4%, P = .90). The rate of patients who ultimately required index level fusion approached significance, but was not statistically different between open and MIS approaches (10.3% vs 4.4%, P = .17). Multivariate regression analysis indicated that the need for eventual index level fusion after lumbar microdiscectomy was statistically predicted in smokers and those patients who underwent revision microdiscectomy (P < .05) in both open and MIS groups. Conclusions: Our results suggest a low likelihood of patients ultimately requiring fusion following microdiscectomy with predictors including smoking status and a history of revision microdiscectomy. PMID- 29456911 TI - Correlation Between Lumbopelvic and Sagittal Parameters and Health-Related Quality of Life in Adults With Lumbosacral Spondylolisthesis. AB - Study Design: Secondary analysis of prospective, multicenter data. Objective: To evaluate impact of sagittal parameters on health-related quality of life (HRQoL) in adults with lumbosacral spondylolisthesis. Methods: Adults with unoperated lumbosacral spondylolisthesis were identified in the Spinal Deformity Study Group database. Pearson's correlations were calculated between SF-12 (Short Form 12)/Scoliosis Research Society-30 (SRS-30) scores and radiographic parameters (C7 sagittal vertical axis [SVA] deviation, T1 pelvic angle, pelvic tilt [PT], pelvic incidence, sacral slope, slip angle, Meyerding slip grade, Labelle classification). Main effects linear regression models measured association between individual health status measures and individual radiographic predictor variables. Results: Forty-five patients were analyzed (male, 15; female, 30; average age 40.5 +/- 18.7 years; 14 low-grade, 31 high-grade). For low-grade slips, SVA had strong negative correlations with SF-12 mental component score (MCS), SRS-30 appearance, mental, and satisfaction domains (r = -0.57, r = -0.60, r = -0.58, r = -0.53, respectively; P < .05). For high-grade slips, slip angle had a moderate negative correlation with SF-12 MCS (r = -0.36; P = .05) and SVA had strong negative correlations with SF-12 physical component score (PCS), SRS 30 appearance and activity domains (r = -0.48, r = -0.48, r = -0.45; P < .05) and a moderate negative correlation with SRS-30 total (r = -0.37; P < .05). T1 pelvic angle had a moderate negative correlation with SF-12 PCS and SRS-30 appearance (r = -0.37, r = -0.36; P <= .05). For every 1 degrees increase in PT, there was a 0.04-point decrease in SRS appearance, 0.05-point decrease in SRS activity, 0.06 point decrease in SRS satisfaction, and 0.04-point decrease in SRS total score (P < .05). Conclusion: Lumbosacral spondylolisthesis in adults negatively affects HRQoL. Multiple radiographic sagittal parameters negatively affect HRQoLs for patients with low- and high-grade slips. Improvement of sagittal parameters is an important goal of surgery for adults with lumbosacral spondylolisthesis. PMID- 29456912 TI - Dural Tears in Adult Deformity Surgery: Incidence, Risk Factors, and Outcomes. AB - Study Design: Retrospective cohort study. Objectives: Describe the rate of dural tears (DTs) in adult spinal deformity (ASD) surgery. Describe the risk factors for DT and the impact of this complication on clinical outcomes. Methods: Patients with ASD undergoing surgery between 2008 and 2014 were separated into DT and non-DT cohorts; demographics, operative details, radiographic, and clinical outcomes were compared. Statistical analysis included t tests or chi2 tests as appropriate and a multivariate analysis. Results: A total of 564 patients were identified. The rate of DT was 10.8% (n = 61). Patients with DT were older (61.1 vs 56.5 years, P = .005) and were more likely to have had prior spine surgery (odds ratio [OR] = 2.0, 95% confidence interval [CI] = 1.2-3.3, P = .007). DT patients had higher pelvic tilt, lower lumbar lordosis, and greater pelvic incidence lumbar lordosis mismatch than non-DT patients (P < .05). DT patients had longer operative times (424 vs 375 minutes, P = .008), were more likely to undergo interbody fusions (OR = 2.0, 95% CI = 1.1-3.6, P = .021), osteotomies (OR = 2.2, 95% CI = 1.1-4.0, P = .012), and decompressions (OR = 2.3, 95% CI = 1.3 4.3, P = .003). In our multivariate analysis, only decompressions were associated with an increased risk of DT (OR = 3.2, 95% CI = 1.4-7.6, P = .006). There were no significant differences in patient outcomes at 2 years. Conclusions: The rate of DT was 10.8% in an ASD cohort. This is similar to rates of DT reported following surgery for degenerative pathology. A history of prior spine surgery, decompression, interbody fusion, and osteotomies are all associated with an increased risk of DT, but decompression is the only independent risk factor for DT. PMID- 29456914 TI - Is Cervical Bracing Necessary After One- and Two-Level Instrumented Anterior Cervical Discectomy and Fusion? A Prospective Randomized Study. AB - Study Design: Prospective randomized control trial. Objective: To investigate the role of cervical collars in postoperative care following 1- and 2-level instrumented anterior cervical discectomy and fusion (ACDF). Methods: The Cervical Spine Research Society Resident Fellow Grant funded this project. Fifty consecutive patients undergoing 1- or 2-level ACDF surgery were randomized into groups receiving either no brace or a cervical brace for 6 weeks postoperatively. Neck Disability Index scores were recorded preoperatively and at regular follow up visits up to 1 year. Computed tomography scans were read 1 year postoperatively to determine fusion rates, and subsidence was measured as change in middle vertebral distance between initial postoperative and 6-month follow-up lateral cervical radiographs. Results: Twenty-two patients were in the no-brace group, and 22 patients were in the brace group at final follow-up, with an average age of 50 and 55 years, respectively. The no-brace group had a total of 32 operative levels, whereas the brace group had 38 operative levels. There was no statistically significant difference in 1-year postoperative Neck Disability Index scores between the brace (9.30) and no-brace (6.95) groups (P = .28), in 6 month subsidence of all operative levels between the brace (0.85 mm) and no-brace (0.79 mm) groups (P = .72), or in the proportion of fused levels between the brace (89%) and no-brace (97%) groups (P = .37). Conclusions: Our results suggest no advantage in wearing a cervical brace following 1- or 2-level ACDF surgery with respect to 1-year outcome scores, 1-year fusion rates, and 6-month subsidence. PMID- 29456913 TI - Investigating the 7-Year Cost-Effectiveness of Single-Level Cervical Disc Replacement Compared to Anterior Cervical Discectomy and Fusion. AB - Study Design: Cost-effectiveness analysis. Objectives: To determine the 7-year cost-effectiveness of cervical disc replacement (CDR) and anterior cervical discectomy and fusion (ACDF). Methods: We analyzed 7-year Short Form-36 Health Survey data collected from the Prestige Cervical Disc investigational device exemption study (IDE). The SF-6D algorithm was used to convert this data into health state utilities. Costs were calculated from the payer perspective, and quality adjusted life years (QALYs) were used to represent effectiveness. A Markov transition-state model was used to evaluate the cost-effectiveness of single-level CDR versus ACDF, and a Monte Carlo simulation was performed to assess the probabilistic sensitivity of the model. Results: CDR generated a 7 year cost of $172 989 compared to a 7-year cost of $143 714 for ACDF. CDR generated 4.53 QALYs compared to 3.85 QALYs generated by ACDF. The cost effectiveness ratio of CDR was $38 247/QALY, while the cost-effectiveness ratio of ACDF was $37 325/QALY. The incremental cost-effectiveness ratio of CDR was $43 522/QALY, under the willingness to pay threshold of $50 000/QALY. Our probabilistic sensitivity analysis demonstrated CDR would be chosen 56% of the time based on 10 000 simulations. Conclusions: Single-level CDR and ACDF were both cost-effective strategies at 7 years for treating degenerative conditions of the cervical spine. Both the Markov simulation and the Monte Carlo simulation demonstrate CDR to be the more cost-effective strategy at 7 years. Continued analysis of IDE data should be performed to validate long-term cost-effectiveness of these treatment strategies. PMID- 29456916 TI - Spine Degenerative Conditions and Their Treatments: National Trends in the United States of America. AB - Study Design: Retrospective database study. Objective: Low back and neck pain are among the top leading causes of disability worldwide. The aim of our study was to report the current trends on spine degenerative disorders and their treatments. Methods: Patients diagnosed with lumbar or cervical spine conditions within the orthopedic subset of Medicare and Humana databases (PearlDiver). From the initial cohorts we identified subgroups based on the treatment: fusion or nonoperative within 1 year from diagnosis. Poisson regression was used to determine demographic differences in diagnosis and treatment approaches. Results: Within the Medicare database there were 6 206 578 patients diagnosed with lumbar and 3 156 215 patients diagnosed with cervical degenerative conditions between 2006 and 2012, representing a 16.5% (lumbar) decrease and 11% (cervical) increase in the number of diagnosed patients. There was an increase of 18.5% in the incidence of fusion among lumbar patients. For the Humana data sets there were 1 160 495 patients diagnosed with lumbar and 660 721 patients diagnosed with cervical degenerative disorders from 2008 to 2014. There was a 33% (lumbar) and 42% (cervical) increases in the number of diagnosed patients. However, in both lumbar and cervical groups there was a decrease in the number of surgical and nonoperative treatments. Conclusions: There was an overall increase in both lumbar and cervical conditions, followed by an increase in lumbar fusion procedures within the Medicare database. There is still a burning need to optimize the spine care for the elderly and people in their prime work age to lessen the current national economic burden. PMID- 29456915 TI - Short-Term Complications of Anterior Fixation of Odontoid Fractures. AB - Study Design: Retrospective study. Objective: Anterior fixation of odontoid fracture has been associated with high morbidity and mortality in small, single institution series. Identifying risk factors may improve risk stratification and highlight factors that could be optimized preoperatively. The objective of this study was to determine the 30-day complication rate following anterior fixation of odontoid fractures and to identify associated risk factors among patients in a large national database. Methods: Patients who underwent anterior fixation were identified in the American College of Surgeons National Quality Improvement Program database (ACS NSQIP) from 2007 to 2012. Patient demographics, medical comorbidities, perioperative complications, and postoperative complications up to 30 days were analyzed by univariate and multivariate analysis. Results: Overall, 103 patients met criteria for the study. The average age was 73.9 years and patients were predominantly white (85.4%). Cardiac comorbidity was common (66.0%), as were dependent functional status (14.6%) and bleeding disorders (13.6%). Complications occurred in 37.9% of patients, and mortality was high (6.8%). Age, white race, and history of bleeding disorders were independently predictive of complications in the multivariate analysis. The postoperative hospital stay was >5 days for 45.6% of patients. Conclusion: In a large, multicenter database study, anterior fixation of odontoid fracture was associated with high morbidity and mortality. Although advanced age was associated with increased risk of complications, patients undergoing anterior fixation were older, on average, than in prior studies. Bleeding disorder was a potentially modifiable risk factor for complications that could be optimized prior to surgery. PMID- 29456917 TI - Neuromonitoring in Spinal Deformity Surgery: A Multimodality Approach. AB - Study Design: Literature review. Objective: The aim of this study was to provide an overview of the available intraoperative monitoring techniques and the evidence around their efficacy in vertebral column resection. Methods: The history of neuromonitoring and evolution of the modalities are reviewed and discussed. The authors' specific surgical techniques and preferred methods are outlined in detail. In addition, the authors' experience and the literature regarding vertebral column resection and surgical mitigation of neurologic alarms are discussed at length. Results: Risk factors for signal changes have been identified, including preoperative neurologic deficit, severe kyphosis, increased curve magnitude, and significant cord shortening. Even though no evidence-based treatment algorithm exist for signal changes, strategies are discussed that can help prevent alarms and address them appropriately. Conclusion: Through implementation of multimodal intraoperative monitoring techniques, potential neurologic injuries are localized and managed in real time. Intraoperative monitoring is a valuable tool for improving the safety and outcome of spinal deformity surgery. PMID- 29456919 TI - Most Influential Literature in Spinal Tuberculosis: A Global Disease Without Global Evidence. AB - Study Design: Bibliometric review of the literature. Objective: This bibliometric analysis aims to give an overview of the most influential academic literature written on spinal tuberculosis. Methods: All databases included in the Thomson Reuters Web of Knowledge were searched for the most influential publications in spinal tuberculosis. The most cited articles published between 1950 and 2015, with the main focus on orthopedic surgery, were identified using a multistep approach, and a total of 100 articles were included. The publications were then analyzed in this bibliometric analysis. Results: The number of citations ranged from 243 to 36, with an average of 77.11. The articles were published in 34 different journals, and the studies were conducted in 20 different countries. The top 3 countries, India, the United States, and China, published a total of 51% (n = 51) of all articles. Low-burden countries produced 60% (n = 60) of all articles in our list. African centers produced only 4% (n = 4) of all included articles. Conclusions: Indian and Chinese researchers dominate evidence in spinal tuberculosis. Other areas with high disease burden, such as Africa, do not feature. Most publications are retrospective studies with a low level of evidence. PMID- 29456918 TI - Cervical Disc Arthroplasty: A Comprehensive Review of Single-Level, Multilevel, and Hybrid Procedures. AB - Study Design: Systematic review. Objectives: Degenerative disc disease and spondylosis resulting in radiculopathy and retrodiscal myelopathy are among the most frequently encountered cervical spinal disorders. Traditionally, anterior cervical discectomy and fusion (ACDF) has successfully achieved neural decompression and restored intradiscal height in these conditions. Unfortunately, nonunion and iatrogenic adjacent segment pathology associated with fusion procedures in the cervical spine has led to an interest in motion-preserving procedures. Cervical disc arthroplasty (CDA) was developed in hopes of preserving cervical biomechanics while mitigating the complications associated with ACDF. Through a systematic review of both published and ongoing studies on single- and multilevel CDA, and hybrid surgeries, we aim to provide evidence for their safety and efficacy in the treatment of various cervical pathologies. Methods: A systematic search of several large databases, including Cochrane Central, PubMed, ClinicalTrials.gov, and the World Health Organization International Clinical Trials Registry was conducted to identify published studies and ongoing clinical trials on CDA and hybrid surgery. Results: Among the relevant studies reviewed, 3 were randomized controlled trials, 2 systematic reviews, as well as multiple prospective case series, biomechanical studies, and meta-analyses. Conclusion: Over the past decade, multiple high-quality studies have shown that single-level CDA can offer equivalent clinical outcomes with a reduction in secondary procedures and total cost when compared to ACDF. However, more recently there has been an increasing prevalence of 2-level CDA and hybrid surgery. Although the data regarding these multilevel procedures is less robust, it appears that they may be as effective as their single-level counterparts. PMID- 29456920 TI - Evidence-Based Analysis of Adjacent Segment Degeneration and Disease After LIF: A Narrative Review. AB - Study Design: Narrative review. Objectives: The etiology of adjacent segment degeneration (ASDeg) and adjacent segment disease (ASDz) after lumbar interbody fusion (LIF) remains controversial. The aim of this narrative review was to provide an evidence-based analysis of the peer-reviewed literature on clinical studies of ASDeg and ASDz after LIF. Methods: A review was performed utilizing Medline, Embase, and Cochrane databases. Two reviewers independently extracted relevant data from each included study. Statistical comparisons were made when appropriate. Results: Nine articles that matched the inclusion and exclusion criteria were included. All the studies were Level III and retrospective. MINORS scores ranged from 9.5 to 13. Clinical outcomes were assessed in all 9 studies, but only 6 studies used validated outcomes measures. Only 6 studies reported values for both ASDeg and ASDz. ASDeg alone was reported in 3 studies. Due to the variability in the criteria for designation as ASDz (different radiographic modalities) and ASDeg (different outcomes measures), we were unable to calculate frequency-weighted mean values or compare the various surgical techniques. Conclusions: This review highlights the various limitations of the current literature on ASDeg and ASDz after lumbar fusion, specifically the absence of a rigorous definition and classification system and an extraordinary heterogeneity in methodology. There needs to be a fundamental shift in the current ASDeg and ASDz research landscape, toward a consensus, so that the high-level clinical research that is essential for treatment of spinal pathology may become available.

PMID- 29456924 TI - Unaccompanied Children Migrating from Central America: Public Health Implications for Violence Prevention and Intervention. AB - Purpose of Review: Unaccompanied children (UC) migrating to the USA from the Central American countries of El Salvador, Guatemala, and Honduras are an underserved population at high risk for health, academic, and social problems. These children experience trauma, violence, and other risk factors that are shared among several types of interpersonal violence. Recent Findings: The trauma and violence experienced by many unaccompanied children, and the subsequent implications for their healthy development into adulthood, indicate the critical need for a public health approach to prevention and intervention. Summary: This paper provides an overview of the violence experienced by unaccompanied children along their migration journey, the implications of violence and trauma for the health and well-being of the children across their lifespan, prevention and intervention approaches for UC resettled in the USA, and suggestions for adapted interventions to best address the unique needs of this vulnerable population. PMID- 29456922 TI - Propensity Scores in Pharmacoepidemiology: Beyond the Horizon. AB - Purpose of review: Propensity score methods have become commonplace in pharmacoepidemiology over the past decade. Their adoption has confronted formidable obstacles that arise from pharmacoepidemiology's reliance on large healthcare databases of considerable heterogeneity and complexity. These include identifying clinically meaningful samples, defining treatment comparisons, and measuring covariates in ways that respect sound epidemiologic study design. Additional complexities involve correctly modeling treatment decisions in the face of variation in healthcare practice, and dealing with missing information and unmeasured confounding. In this review, we examine the application of propensity score methods in pharmacoepidemiology with particular attention to these and other issues, with an eye towards standards of practice, recent methodological advances, and opportunities for future progress. Recent findings: Propensity score methods have matured in ways that can advance comparative effectiveness and safety research in pharmacoepidemiology. These include natural extensions for categorical treatments, matching algorithms that can optimize sample size given design constraints, weighting estimators that asymptotically target matched and overlap samples, and the incorporation of machine learning to aid in covariate selection and model building. Summary: These recent and encouraging advances should be further evaluated through simulation and empirical studies, but nonetheless represent a bright path ahead for the observational study of treatment benefits and harms. PMID- 29456925 TI - Continuity and change in local immigrant policies in times of austerity. AB - European cities are increasingly being recognised for the role they play in devising and implementing their own migration, integration and diversity policies. Yet very little is known about the local dimension of immigrant policymaking in crisis contexts. This introductory piece offers a rationale for analysing city-level immigrant policies in times of crisis and the salience of using crisis as a metaphor for the state of things, and outlines key scholarly works, debates, concepts and theories. It provides a range of historical and contemporary examples and considerations, and introduces an empirical city case study that is published as part of this mini-symposium. It argues that a crisis lens leads to a systematic understanding of local-level immigrant policymaking in recent and contemporary Western Europe. The mini-symposium's focus and findings should be relevant to both on-going academic and policy debates. PMID- 29456926 TI - Migration and child health in Moldova and Georgia. AB - There is scarce empirical evidence on the relation between migration and child health in Moldova and Georgia-two post-Soviet countries with large out-migration flows in the region. This study uses nationally representative data collected in 2011-2012 in Moldova (N = 1601) and Georgia (N = 1193) to investigate how children's health associates with five transnational characteristics: migrant and return-migrant household types, parental migration and parental divorce, maternal and/or paternal migration and caregiver's identity, the duration of migration, and remittances. Findings show that, regardless of the transnational family setting, children of migrants have overall positive or no differing health compared to children in non-migrant households. However, significant gender differences are found in both countries. More often than not, Moldovan and Georgian girls are more at risk of having poorer health when living transnationally. These results add nuance to a field of research that has mainly emphasized negative outcomes for children in transnational care.

AB - Mental health problems in children and adolescents include several types of emotional and behavioural disorders, including disruptive, depression, anxiety and pervasive developmental (autism) disorders, characterized as either internalizing or externalizing problems. Disruptive behavioural problems such as temper tantrums, attention deficit hyperactivity disorder, oppositional, defiant or conduct disorders are the commonest behavioural problems in preschool and school age children. The routine Paediatric clinic or Family Medicine/General Practitioner surgery presents with several desirable characteristics that make them ideal for providing effective mental health services to children and adolescents. DSM-5 and ICD-10 are the universally accepted standard criteria for the classification of mental and behaviour disorders in childhood and adults. The age and gender prevalence estimation of various childhood behavioural disorders are variable and difficult to compare worldwide. A review of relevant published literature was conducted, including published meta-analyses and national guidelines. We searched for articles indexed by Ovid, PubMed, PubMed Medical Central, CINAHL, EMBASE, Database of Abstracts and Reviews, and the Cochrane Database of Systematic reviews and other online sources. The searches were conducted using a combination of search expressions including "childhood", "behaviour", "disorders" or "problems". Childhood behaviour and emotional problems with their related disorders have significant negative impacts on the individual, the family and the society. They are commonly associated with poor academic, occupational, and psychosocial functioning. It is important for all healthcare professionals, especially the Paediatricians to be aware of the range of presentation, prevention and management of the common mental health problems in children and adolescents. PMID- 29456929 TI - Controversies in diagnosis and management of Kawasaki disease. AB - Kawasaki disease (KD) is a common medium vessel systemic vasculitis that usually occurs in small children. It has a predilection for the coronary arteries, but other medium sized arteries can also be involved. The etiology of this disorder remains a mystery. Though typical presentation of KD is quite characteristic, it may also present as incomplete or atypical disease in which case the diagnosis can be very challenging. As both incomplete and atypical forms of KD can be associated with serious coronary artery complications, the pediatrician can ill afford to miss these diagnoses. The American Heart Association has enunciated consensus guidelines to facilitate the clinical diagnosis and treatment of this condition. However, there are still several issues that remain controversial. Intravenous immunoglobulin remains the cornerstone of management but several other treatment modalities, especially glucocorticoids, are increasingly finding favour. We review here some of the contemporary issues, and the controversies thereon, pertaining to management of KD.

Tic disorders (TD) are common co morbidities in paediatric ADHD patients with or without pharmacotherapy treatment. There has been conflicting evidence of the role of psychostimulants in either precipitating or exacerbating TDs in ADHD patients. We carried out a literature review relating to the management of TDs in children and adolescents with ADHD through a comprehensive search of MEDLINE, EMBASE, CINAHL and Cochrane databases. No quantitative synthesis (meta-analysis) was deemed appropriate. Meta analysis of controlled trials does not support an association between new onset or worsening of tics and normal doses of psychostimulant use. Supratherapeutic doses of dextroamphetamine have been shown to exacerbate TD. Most tics are mild or moderate and respond to psychoeducation and behavioural management. Level A evidence support the use of alpha adrenergic agonists, including Clonidine and Guanfacine, reuptake noradrenenaline inhibitors (Atomoxetine) and stimulants (Methylphenidate and Dexamphetamines) for the treatment of Tics and comorbid ADHD. Priority should be given to the management of co-morbid Tourette's syndrome (TS) or severely disabling tics in children and adolescents with ADHD. Severe TDs may require antipsychotic treatment. Antipsychotics, especially Aripiprazole, are safe and effective treatment for TS or severe Tics, but they only moderately control the co-occurring ADHD symptomatology. Short vignettes of different common clinical scenarios are presented to help clinicians determine the most appropriate treatment to consider in each patient presenting with ADHD and co morbid TDs. PMID- 29456931 TI - Abdominal obesity adversely affects bone mass in children. AB - AIM: To determine the effect of childhood obesity and insulin resistance on bone health. METHODS: We conducted a cross sectional study in pubertal adolescents and young adults 13-20 years old who were either overweight/obese or normal weight. Participants were Tanner 3 or above for pubertal stage, and had fasting blood work done to measure glucose, insulin, C-reactive protein and lipid levels. Homeostatic model of insulin resistance (HOMA-IR) was calculated using the formula (Fasting Blood Glucose *Insulin/405). Body composition and bone mineral density were measured using dual energy X-ray absorptiometry (DXA; Hologic QDR 4500, Waltham, MA, United Kingdom). RESULTS: Percent trunk fat was associated inversely with whole body bone mineral content (BMC), whereas HOMA-IR was associated positively with whole body BMC. CONCLUSION: Our results suggest that abdominal adiposity may have an adverse effect on whole body bone parameters and that this effect is not mediated by insulin resistance. PMID- 29456932 TI - Neither hereditary periodic fever nor periodic fever, aphthae, pharingitis, adenitis: Undifferentiated periodic fever in a tertiary pediatric center. AB - AIM: To describe the frequency and clinical characteristics of patients with undifferentiated periodic fever (UPF) and to investigate whether a clinical classification of UPF based on the PRINTO-Eurofever score can help predicting the response to treatment and the outcome at follow-up. METHODS: Clinical and therapeutic information of patients with recurrent fever who presented at a single pediatric rheumatology center from January 2006 through April 2016 were retrospectively collected. Patients with a clinical suspicion of hereditary periodic fever (HPF) syndrome and patients with clinical picture of periodic fever, aphthae, pharingitis, adenitis (PFAPA) who were refractory to tonsillectomy underwent molecular analysis of five HPF-related genes: MEFV (NM_000243.2), MVK (NM_000431.3), TNFRSF1A (NM_001065.3), NLRP3 (NM_001079821.2), NLRP12 (NM_001277126.1). All patients who had a negative genetic result were defined as UPF and further investigated. PRINTO-Eurofever score for clinical diagnosis of HPF was calculated in all cases. RESULTS: Of the 221 patients evaluated for periodic fever, twelve subjects with a clinical picture of PFAPA who were refractory to tonsillectomy and 22 subjects with a clinical suspicion of HPF underwent genetic analysis. Twenty-three patients (10.4%) resulted negative and were classified as UPF. The median age at presentation of patients with UPF was 9.5 mo (IQR 4-24). Patients with UPF had a higher frequency of aphthae (52.2% vs 0%, P = 0.0026) and musculoskeletal pain (65.2% vs 18.2%, P = 0.0255) than patients with genetic confirmed HPF. Also, patients with UPF had a higher frequency of aphthous stomatitis (52.2% vs 10.7%, P < 0.0001), musculoskeletal pain (65.2% vs 8,0%, P < 0.0001), and abdominal pain (52.2% vs 4.8%, P < 0.0001) and a lower frequency of pharyngitis (56.6% vs 81.3%, P = 0.0127) compared with typical PFAPA in the same cohort. Twenty-one of 23 patients with UPF (91.3%) received steroids, being effective in 16; 13 (56.2%) were given colchicine, which was effective in 6. Symptoms resolution occurred in 2 patients with UPF at last follow-up. Classification according to the PRINTO-Eurofever score did not correlate with treatment response and prognosis. CONCLUSION: UPF is not a rare diagnosis among patients with periodic fever. Clinical presentation place UPF half way on a clinical spectrum between PFAPA and HPF. The PRINTO-Eurofever score is not useful to predict clinical outcome and treatment response in these patients. PMID- 29456933 TI - Pediatricians lack knowledge for the diagnosis and management of functional constipation in children over 6 mo of age. AB - AIM: To assess the knowledge of general pediatricians througout Indonesia about the diagnosis and treatment of childhood constipation. METHODS: A comprehensive questionnaire was distributed to general pediatricians from several teaching hospitals and government hospitals all over Indonesia. RESULTS: Data were obtained from 100 pediatricians, with a mean of 78.34 +/- 18.00 mo clinical practice, from 20 cities throughout Indonesia. Suspicion of constipation in a child over 6 mo of age arises when the child presents with a decreased frequency of bowel movements (according to 87% of participants) with a mean of one bowel movement per 3.59 +/- 1.0 d, hard stools (83%), blood in the stools (36%), fecal incontinence (33%), and/or difficulty in defecating (47%). Only 26 pediatricians prescribe pharmacologic treatment as first therapeutic approach, while the vast majority prefers nonpharmacologic treatment, mostly (according to 68%) The preferred nonpharmacologic treatment are high-fiber diet (96%), increased fluid intake (90%), toilet training (74%), and abdominal massage (49%). Duration of non pharmacological treatment was limited to 1 to 2 wk. Seventy percent of the pediatricians recommending toilet training could only mention some elements of the technique, and only 15% was able to explain it fully and correctly. Lactulose is the most frequent pharmacologic intervention used (87% of the participants), and rectal treatment with sodium citrate, sodium lauryl sulfo acetate, and sorbitol is the most frequent rectal treatment (85%). Only 51% will prescribe rectal treatment for fecal impaction. The majority of the pediatricians (69%) expect a positive response during the first week with a mean (+/- SD) of 4.1 (+/- 2.56) d. Most participants (86%) treat during one month or even less. And the majority (67%) stops treatment when the frequency and/or consistency of the stools have become normal, or if the patient had no longer complaints. CONCLUSION: These data provide an insight on the diagnosis and management of constipation in childhood in Indonesia. Although general pediatricians are aware of some important aspects of the diagnosis and mangement of constipation, overall knowledge is limited. Efforts should be made to improve the distribution of existing guidelines. These findings highlight and confirm the difficulties in spreading existing information from guidelines to general pediatricians. PMID- 29456934 TI - Outcomes of transconjuctival sutureless 27-gauge vitrectomy for stage 4 retinopathy of prematurity. AB - AIM: To report our initial experience with lens-sparing vitrectomy for stage 4 retinopathy of prematurity using the 27-gauge (G) system. METHODS: This retrospective case series involved nine eyes of five babies with active stage 4 ROP, who underwent 27-G lens-sparing vitrectomy. Surgery was done using 27-G valved cannulas and sclerotomies were made 1.5 mm from the limbus. Bilateral sequential vitrectomy was done in eight eyes. RESULTS: At one-year follow-up, anatomical outcome was favourable in all nine (100%) eyes. High-speed cutting and smaller sclerotomies were helpful in reducing the intra and post-operative complications. CONCLUSION: 27-G vitrectomy is well suited for stage 4 ROP surgeries. PMID- 29456935 TI - Radiological Evaluation of Cochlear Orientation and Its Implications in Cochlear Implantation. AB - To test whether there are variations in cochlear orientation with respect to age and sex, and its relevance in cochlear implant surgery. Implant otologists rely upon the anatomic landmarks including the facial recess and round window niche and round window membrane for accessibility and placement of electrode array into scala tympani of basal turn of cochlea. Anecdotally, surgeons note variations in cochlear orientation with respect to age. Cochlear orientation studied radiologically by pre-operative CT scan of temporal bone can guide a Surgeon's approach to cochlear implantation. To investigate the changes in cochlear orientation with respect to age and sex; and its relevance in cochlear implantation. A retrospective analytical study was performed on CT scans of temporal bones in patients (of our hospital from July 2013 to January 2015 i.e. for a period of 18 months) with no congenital or radiological abnormalities of cochlea. The basal turn angulations of cochlea varied with age and majority of change occurred during early age. The basal turn angulations of cochlea in difficult situations during cochlear implantation were correlated with the data. There is a significant variation in cochlear orientation as measured radiologically by basal turn angulations relative to midsagittal plane. The more obtuse and acute basal turn angulations have implications like difficulty in cochleostomy and electrode placement during cochlear implantation.

AB - Though the association between follicular carcinoma and bone metastasis is well established, the site-wise distribution is not known. One hundred seventy-three patients of follicular carcinoma presenting between 2003 and 2011 were selected from 1093 patients of follicular lesions presenting at a single institution. Of these, 59 (34%) with bone metastasis were included in the study. Fifty of the 59 patients (84.7%) had metastasis at presentation, while 9 developed bone metastasis during follow-up. Sixty-one percent had solitary metastasis, 15 (25.4%) had multiple bone involvement, while 8 patients (13.6%) had synchronous lung metastasis. Overall, the spine was the commonest site of bone metastases, seen in 20 patients (33.9%), followed by the pelvis, skull, long bones and sternum. Bone metastasis is a known phenomenon in follicular carcinoma. The spine is the commonest site followed by the pelvis. PMID- 29456937 TI - To Evaluate and Compare the Result of Ossiculoplasty Using Different Types of Graft Materials and Prosthesis in Cases of Ossicular Discontinuity in Chronic Suppurative Otitis Media Cases. AB - Chronic suppurative otitis media, with and without cholesteatoma, frequently results in disruption of the ossicular chain. The present study was designed to compare the outcome using autologous ossicle and titanium prosthesis in two groups of suitable patients presenting with chronic suppurative otitis media for middle ear reconstructive surgeries. A prospective study done from July 2012 to December 2013, at Mahatma Gandhi Medical College and Hospital, Sitapura, Jaipur (Rajasthan). The target group included patients with chronic suppurative otitis media admitted and planned for reconstructive middle ear surgery. The study group patients among the target group requiring certain ossicular reconstruction. The patients included were patients with CSOM with or without cholesteatoma in which there was ossicular discontinuity. The patients were divided in two groups A and B. In group A patients autologous incus was used and in group B titanium prosthesis either TORP or PORP was used for ossicular replacement. Out of 340 patients as target group, 88 patients were included in study group. Further 88 patients of study group, 51 patients were included in group A; rest 37 patients were included in group B. In group B patients partial ossicular replacement platinum prosthesis was used in 31 patients while in rest 6 patients a total ossicular replacement prosthesis was used. Out of 88 patients, 79 were primary cases and 9 were revision cases. Pre and post operative air bone gap were noted. Pre operatively both of the groups were identical in relation to air-bone gap. The postoperative air-bone gap was calculated as the difference between postoperative air conduction and preoperative bone conduction. On comparison of preoperative and post-operative hearing results there was improvement in air conduction threshold and air bone gap in both the groups. Post operatively difference in air bone gap closure between group A and group B was found statistically significant (P value = 0.032) suggesting better hearing outcomes after using titanium ossicular replacement prosthesis. On comparing partial or total ossicular replacement prosthesis no significant difference was found for the audiological outcome (P = 0.434). Various prognostic factors were also noted for air bone gap closure. Titanium ossicular replacement prosthesis have better outcome, and no significant difference found in audiological outcome for TORP and PORP. PMID- 29456938 TI - Deep Neck Space Infections-A Study in Diabetic Population in a Tertiary Care Centre. AB - This study is intended to analyze the clinical profile and outcomes of deep neck space infection in diabetic patients in our tertiary care centre. A prospective study of 1 year duration from 30th September 2015 to 30th September 2016 at department of Otorhinolaryngology, Gauhati Medical College and Hospital, Guwahati. A total of 45 diabetic patients who presented with DNSI are included in this study. Their demographic profile, etiology, bacteriology, treatment, duration of hospital stay, complications and outcomes have been analyzed. 45 patients were recorded; 32 (71.11%) were men, and 13 (45%) were women, with a mean age of 63.27 +/- 7.55 years. There were 30 patients (66.67%) who had associated systemic diseases apart from diabetes mellitus. The parapharyngeal space in 13 patients (28.89%) was the most commonly involved space. Odontogenic infections in 18 patients (40%) and upper airway infections 9 patients (20%) were the two most common causes. Klebsiella pneumonia in 29 patients (64.44%), was the commonest organism isolated through pus cultures. All the patients except one (97.78%) came with abscess and underwent surgical drainage. One patient (2.22%) with carbuncle underwent regular dressing. Six patients (13.33%) had major complications. Those patients with other underlying systemic diseases or complications tended to have a longer hospital stay and were older. No cases of death has been reported. (mortality rate, 0%). DNSI patients with diabetes have a more severe clinical course. They are likely to have complications more frequently and a longer duration of hospital stay. In clinical practices while dealing with these patients more vigilance is required. On admission empirical antibiotics should cover K. pneumonia. Early surgical drainage remains the main method of treatment. Primary prevention can be achieved by orodental hygiene, regular dental check ups and in this part of the country by avoidance of substance abuse like tobacco chewing.

AB - The cross sectional study was conducted in Universiti Kebangsaan Malaysia Medical Center (UKMMC), Malaysia from August 2012 to December 2013. All patients implanted with in UKMMC from December 2001 until December 2012 was included. Glasgow Benefit Inventory (GBI) questionnaires and UKMMC questionnaires were used as part of the assessment tool. The GBI is a scoring which measures the change in health status produced by surgical interventions. UKMMC questionnaires was invented by our department to assess questions related to social and life style of patients and also the cosmetic perspective Baha implant and other daily related activities. The audiological assessment was assessed using hearing aid gain threshold. Complication with regards to skin reaction was graded using Holger Skin Classification. A total of 40 patients underwent Baha implant were recruited but only 35 patients fulfilled the criteria and included in this study for analysis. Age of patients ranged from 5 year old to 38 year old, with median of 13 years old. There were 22 patients (62.8%) were male and 13 patients (37.1%) were females. Almost all cases were canal atresia except one adult patient was a case of bilateral chronic discharging ear with chronic irritation with ear mould. Majority of patients 21 (60%) have hearing level of moderate to severe hearing loss (40-89 dB) and 14 patients (40%) have mild to moderate hearing loss (20-39 dB). The level of hearing was retested post operatively. All of the patients have improvement in their aided hearing with the range of 10-25 dBL which is statistically significant at p value of <0.05. The GBI was scored positively in all subscales. Majority of patients (91.4%) used BAHA more than 4 h per day and 88.6% agreed that BAHA is cosmetically acceptable. All patients experienced some form of skin irritation (Holger grade 1-2) however only 20% required surgical intervention. All our patients have range of 10-25 dB improvement of their aided hearing which is statistically significant at p value of <0.05. BAHA has been proven to show significant benefit in audiological improvement and quality of life. PMID- 29456940 TI - Mrmc Neo Surgical Ventilating Port and Neo Attic Malleo-Incudal Complex in Endoscopic Management of Limited Attico-Antral Cholesteatoma. AB - To study functional outcome of the endoscopic management of limited attico-antral cholesteatoma in terms of visualization of sac, cholesteatoma disease clearance, ABG closure improvement, preservation of residual anatomy and recurrence of disease. It is a prospective study done during Feb 2016 to March 2017 done on 20 pts with limited attico-antral cholesteatoma with CT confirmation. Endoscopic management of limited attico-antral cholesteatoma with complete removal of sac, infected discharge and granulations along with creation of MRMC Neo surgical ventilating port (joining Anterior & posterior isthmuses) done in cases where residual attic anatomy was present to establish physiological attic ventilation and drainage. Whereas in cases of attic and ossicular erosion, ossiculoplasty along with neo attic malleo-incudal complex (with composite tragal cartilage with perichondrium graft) for lateral attic wall reconstruction was done to prevent attic retraction. Patients had mean pre op ABG of 36.29 +/- 6.29 and mean post op ABG closure of 16.33 +/- 6.50 with no recurrence of cholesteatoma at 6 months of follow up. Patient showed significant (55%) improvement in hearing with all having graft uptake in which four cases having mild pars tensa retraction which recovered later without any intervention. Thus creation of new MRMC Neo surgical ventilating port or neo attic malleo-incudal complex with endoscopic approach allows better visual access to clear the limited attico-antral disease with sparing of normal residual attic anatomy along with physiological ventilation and drainage having better hearing results and outcome. PMID- 29456941 TI - The Learning Curve in Surgical Practice and Its Applicability to Rhinoplasty. AB - The learning curve as a concept has been considered, discussed and debated in medical education and healthcare for over two decades. The precise usage has been recognised in surgical disciplines both broad specialties and sub-specialties. Rollin Daniel in his book stated that, rhinoplasty is the most difficult of all cosmetic operations for three reasons, (a) nasal anatomy is highly variable, (b) the procedure must correct form and function and (c) the final result must meet the patients expectations. With this in mind a study was carried on the perception of learning curve in rhinoplasty based on a surgeon questionnaire at Marien Hospital, Stuttgart, Germany under Prof. Gubisch. Aims of the study were, (1) to extract the perception of learning curve of Rhinoplasty from surgeons across a spectrum of experience, i.e. less experienced to experienced, (2) To calculate the perception of learning curve in rhinoplasty as for other surgical procedures i.e. minimum number, interquartile range, surgical time, accelerators, (3) To chart-out a road-map for a novice rhinoplasty surgeon for continued improvement in surgical skills and ability. The conclusion derived was the concept of learning curve in rhinoplasty cannot be applied to the operation of Septo-Rhinoplasty as a whole because the two factors i.e. interquartile range and minimum number to achieve proficiency have a wide range and cannot be generalized. It is thought that each type of Rhinoplasty should be dealt with separately and learning curve calculated accordingly, i.e. hump reduction, crooked nose and augmentation rhinoplasty.

To correlate disease severity with the presence of biofilms and host risk factors. To assess outcome of Sinus Surgery 2 weeks post operatively in terms of presence of bacteria and their ability to form biofilm. Prospective study. 50 cases of chronic rhino-sinusitis requiring Functional Endoscopic Sinus Surgery admitted in SDM Hospital, Dharwad, Karnataka were studied using intra-operative mucosal samples for microbiological analysis. The organisms isolated were tested for biofilm forming ability using three in vitro tests. Severity of disease was assessed using SNOT 22 scoring system. Of 50 cases studied, 66% showed presence of chronic rhino-sinusitis with polyposis and had higher SNOT scores compared to those without polyps. Bacterial isolates were obtained from only 17 samples. Staphylococcus species was isolated from 16 samples and Klebsiella pneumoniae from one. 11 Staph spp. isolates showed biofilm forming ability in vitro. Postoperative events in 3 cases yielded biofilm-forming Staphylococcus. Staphylococcus was the most dominant organism isolated and 11 isolates were biofilm formers. Thus the detection of biofilm forming organisms can be considered as a negative prognostic indicator and should forewarn the surgeon about the risk of recurrence.

AB - To quantify the successful outcome in patients following optic nerve decompression in post traumatic unilateral optic neuropathy in form of improvement in visual acuity. A prospective study was carried out over a period of 5 years (January 2011 to June 2016) at civil hospital Ahmedabad. Total 20 patients were selected with optic neuropathy including patients with direct and indirect trauma to unilateral optic nerve, not responding to conservative management, leading to optic neuropathy and subsequent impairment in vision and blindness. Decompression was done via Transnasal-Ethmo-sphenoidal route and outcome was assessed in form of post-operative visual acuity improvement at 1 month, 6 months and 1 year follow up. After surgical decompression complete recovery of visual acuity was achieved in 16 (80%) patients and partial recovery in 4 (20%). Endoscopic transnasal approach is beneficial in traumatic optic neuropathy not responding to steroid therapy and can prevent permanent disability if earlier intervention is done prior to irreversible damage to the nerve. Endoscopic optic nerve surgery can decompress the traumatic and oedematous optic nerve with proper exposure of orbital apex and optic canal without any major intracranial, intraorbital and transnasal complications. PMID- 29456944 TI - Choanal Atresia: Birth Without Breath. AB - Bilateral Choanal atresia is a medical emergency. Corrective surgery is the mainstay of the treatment. Hegar's dilator was used in all cases to break the bony/membranous atretic plate. The 22 cases of choanal atresia all operated by the first author were included in this study. Eight cases were 1-5 year old with bilateral choanal atresia and all required immediate surgery as they had repeated attacks of respiratory distress and cycle of cyanosis. Eight cases were of CHARGE Syndrome. All the cases were operated under general anaesthesia. Hegar's dilators were used and nasal stents were placed in all cases. Although complete nasal patency was achieved by surgery, in 8 cases, neonates could not survive due to the CHARGE Syndrome. The mortality was unrelated to the surgery. The 14 cases which were not related to CHARGE Syndroma had a good postoperative recovery. 3 cases were above 15 years old with unilateral complete bony/membranous choanal atresia and they presented with continuos nasal discharge. Hegar's dilators are a safe and simple method of surgery for choanal atresia. Nasal stenting is mandatory to prevent restenosis. PMID- 29456945 TI - Audiological Profile in Primary Sjogren's Syndrome in a Tertiary Care Setting and its Clinical Implications. AB - This study aims to assess the frequency and the profile of hearing loss among patients with primary Sjogren's syndrome in a tertiary care hospital in India and to look for an association between hearing loss and immunological parameters (anti-SSA antibody, anti-SSB antibody, anticardiolipin antibodies, complements C3 and C4). This prospective observational study was done from January 2011 to October 2011 on consecutive patients diagnosed with primary Sjogren's syndrome in our tertiary care hospital. All patients underwent a puretone audiogram, tympanogram and acoustic reflex testing. The results of the tests were correlated with clinical and immunological findings. The frequency of audiometrically confirmed hearing loss in primary Sjogren's syndrome was estimated to be 78.38 %, though only 17.24 % complained of hearing loss; minimal to mild sensorineural hearing loss were the most common varieties. The commonest finding on tympanometry was 'A' type curve and acoustic reflex was absent in 18.92 % of cases. There was no association between hearing loss and age, sicca symptoms, systemic symptoms or immunological test results in primary Sjogren's syndrome. There was a high prevalence of hearing loss among patients with primary Sjogren's syndrome, but most patients were unaware of this. Hearing assessment and regular monitoring of hearing thresholds is advisable for all patients with primary Sjogren's syndrome. PMID- 29456946 TI - Detection of Epstein-Barr and Human Papilloma Viruses in the Middle Ear Squamous Cell Carcinoma. AB - The uncommon ear tumor of middle ear squamous cell carcinoma (MESCC) is thought to be associated with the history of long-term chronic otitis media in the most cases. The main etiologic factor of MESCC is still unclear and may be multifactorial. Infections of Epstein-Barr virus (EBV) and Human Papillomavirus (HPV) are considered as one of the etiologic factor of MESCC. Previous studies have shown that the EBV and HPV have been detected in MESCC. Although the EBV and HPV have been implicated in human malignancies, their roles in pathogenesis of MESCC have not been elucidated. There has never been report on the presence of EBV and HPV in Indonesian MESCC. This study aimed to determine the presence of EBV and HPV in MESCC. Seven paraffin-embedded tissues of speciment from biopsy were analyzed for the presence of EBV and HPV by immunohistochemistry, stained using polyclonal antibody anti EBNA1 and anti HPV. The samples consisted of 4 (57 %) males and 3 (43 %) females with age range of 26-87 years old. Immunohistochemistry result demonstrated that EBV was detected in three of seven (43 %) and HPV in two of seven (29 %) samples. Coexistence of the presence of EBV and HPV were found in one of seven (14 %) sample. The presence of EBV and HPV in MESCC suggests that viral infection may play an important etiologic role in the carcinogenesis of middle ear. PMID- 29456947 TI - Aesthetic and Functional Evaluation of Total Nasal Reconstructions. AB - The loss of a portion or the totality of the nose has great relevance on the perception of the beauty of a face and can result in a catastrophic quality of life impairment. Several surgical techniques are currently available for the reconstruction of the nasal pyramid. However, there are very few nasal reconstruction quality evaluation protocols that allow the surgeon to choose objectively the best technique for each kind of defects. Six total nasal reconstruction performed in University of Sassari Maxillofacial Unit were evaluated with a protocol that investigate objectively and subjectively the surgical aesthetic and functional outcome. Sensitivity recovery on the reconstructive flaps was also assessed. Patients reported a satisfactory nasal reconstruction both functionally and aesthetically. Sensitivity recovery on the forehead flap was always present even after pedicle resection or in case of traumatic section of the infraorbital nerve. The use of a three layer reconstruction has proved a viable technique both aesthetically and functionally. In particular the use of the forehead flap to reconstruct the outer layer of the nose allows to carry a tissue with very similar characteristics to the original with a recovery of the sensitivity almost complete. PMID- 29456948 TI - Is Routine Use of High Resolution Computerized Tomography of Temporal Bone in Patients of Atticoantral Chronic Suppurative Otitis Media without Intracranial Complications Justified? AB - Role of high resolution computerized tomography (HRCT) of temporal bone is established in cases of atticoantral chronic suppurative otitis media (CSOM) with intracranial complications. Routine use of HRCT in management of patients of atticoantral CSOM without intracranial complications has been an issue of debate. The aim of this study was to evaluate the routine use of HRCT of temporal bone in such cases. This study was a prospective study done at LG hospital, AMC MET Medical College, Ahmedabad to evaluate and compare the temporal bone findings in HRCT and intraoperative findings in 100 patients with atticoantral CSOM. All patients underwent HRCT screening followed by surgical exploration of middle ear cleft. In extent of disease HRCT showed very high sensitivity and specificity for epitympanum (100, 94%) and mesotympanum (98, 98%) areas. It gave valuable information of disease extent in hidden areas like sinus tympani and facial recess of mesotympanum. HRCT satisfactorily delineated malleus and incus erosion but had 75% sensitivity for detecting erosion of stapes suprastructure, though specificity was of 97%. For bony anatomical landmarks HRCT showed very high sensitivity and specificity for detecting erosion of lateral semicircular canal, tegmen tympani and sinus plate. Detection of facial canal erosion on HRCT had moderate sensitivity of 75%. We concluded that routine use of HRCT is justified as a reliable preoperative tool in patients with atticoantral CSOM without intracranial complications and it helps to plan type of surgical intervention. HRCT has limited role to distinguish between granulations and cholesteatoma and also to delineate stapes supra structure and facial nerve canal. PMID- 29456949 TI - Clarithromycin in the Management of Chronic Rhinosinusitis: Preliminary Results of a Possible Its New Use. AB - The aim of this study is to evaluate the efficacy and safety of prolonged therapy with low-dose clarithromycin in patients with chronic rhinosinusitis with polyps (CRSwP) after endoscopic sinus surgery (ESS). A total of 10 patients with CRSwP were identified and subjected to bilateral ESS. In post-operative patients they were treated with nasal wash with saline solution and steroid sprays (beclomethasone). During follow-up, after 30-40 days after the operation (M = 35.4 SD = +4.33), patients reported a worsening of symptoms with onset of nasal obstruction; reduction/loss of smell; headache; onset of viscous secretions and therefore all patients continued therapy with saline nasal irrigation, topical steroid therapy and started macrolide (clarithromycin 500 mg/pill: 1 pill/day for 3 days a week for 1 month). 22-item SinoNasal Outcome Test (SNOT-22) and a score to the endoscopic evaluation (endoscopic appearance score, EAS) before and after treatment were performed to evaluate efficacy of treatment. The results of the SNOT-22 and EAS showed statistically significant improvements (p < 0.05) for some parameters such as: the need to blow nose, sneezing, hyposmia, viscous mucous secretions about the SNOT-22 and reduction of secretions and edema of the nasal mucosa about the EAS. The preliminary results of our study show that the low-dose clarithromycin for a period of 1 month can improve patient complaints with CRSwP not only through the antibacterial properties but also for the immunomodulatory characteristics. PMID- 29456950 TI - Cerebrospinal Fluid Leakage During Temporal Bone Surgery: Selecting Intra operative Dural Closure with a Dumbbell-Shaped Muscle Graft as a Surgical Approach. AB - Cerebrospinal fluid (CSF) leakages of the temporal bone may arise during mastoid surgery. The leakages can have multiple potential etiologies, for instance, using a cutting burr near the bony tegmen or monopolar electrocautery on the surface of the dura mater. In this paper, we introduced an effective and simple technique for the management of CSF leakages of the temporal bone. In a prospective case series, 36 patients (16 males and 20 females) who have had an experience of incidental or inevitable CSF otorrhea or otorhinorrhea during temporal bone surgery were selected. All patients were treated using a muscle graft in a dumbbell-shaped design through the dura defect at the Amir-Alam University Hospital between April 2005 and November 2008. The mean size of the defects was 5 mm (a range of 2-10 mm). A dumbbell-shaped autologous muscle graft was immediately successful in sealing the leakage in all patients. Only five patients (13.8%) had some evidence of leakage remaining on the day after the operation, which was subsequently resolved by conservative management in four of them (11.1%). Only one patient (2.7%) was subjected to a second operation for a new defect. Recurrence of CSF leakage or other related complications were not observed during about 7 years of follow up. A free autologous muscle graft, using the dumbbell technique through a small to moderate dura defect is an effective, easily performed, and safe method to seal iatrogenic leakages of the temporal bone.

AB - To analyze the clinical presentation, management and outcomes of patients with pituitary adenoma treated by Endoscopic Endo-nasal Trans-sphenoidal (EETS) excision. Study was conducted on the basis of medical records of 14 patients who had undergone EETS excision of pituitary adenomas. The data obtained was assessed for demographic and clinical characteristics, radiographic features and post operative outcomes. Study included 10 males and 4 females. Mean age of patients was 46.43 years (range 16-70 Years). Most common presentation was diminished vision reported in 79% patients. Features of acromegaly encountered in 21% cases. Location of majority of tumors was sellar with supra-sellar extension (71%) followed by sellar (14%), sellar with para-sellar extension (7%) and sellar with supra-sellar and para-sellar extensions (7%). Total tumor resection was achieved in 64% cases and sub-total resection in 36% cases. One of the lesions on biopsy revealed granulomatous pathology. No post-operative complication was seen in 71% patients. Transient Diabetes Insipidus was observed in 21% cases that resolved within 3-4 days. One patient expired due to meningitis and septicemia. One patient had CSF leak that was effectively managed by placing lumbar drain. There was significant improvement in visual symptoms and hormonal levels. Average hospital stay was 13.54 days and mean follow up period was 13 months. EETS approach is safe, minimally invasive and effective surgical technique for resection of pituitary adenomas with low post-operative morbidity, reduced hospital stay and better remission of symptoms. PMID- 29456952 TI - Clinicopathological Significance of Tumor Lymphatic Vessel Density in Head and Neck Squamous Cell Carcinoma. AB - Various studies have demonstrated that the lymphatic system is the additional route for solid tumor metastasis. Lymph nodes metastasis in Head and neck squamous cell carcinoma (HNSCC) is a major prognostic indicator for disease progression and a guide for therapeutic strategies. We conducted a study to compare intratumoral (IT) and peritumoral (PT) lymphatic vessel density (LVD) in HNSCC using lymphatic marker D2-40 and its correlation with lymph node metastasis, histological grading and other clinicopathological parameters. Fifty specimen of HNSCC with modified radical neck dissection tissue were included in the study group. Tissue from tumor, peritumoral tissue, tumor margin and all the lymph nodes were processed for paraffin wax blocks and histopathological diagnosis. Immunohistochemical profile of lymphatic vessels in intratumoral and peritumoral tissue was assessed by subjecting one section each from the tumor and peritumoral tissue to D2-40 immunostain. To determine LVD, four fields with the highest LVD (hot spots) were identified. The mean values were calculated by taking an average of all the measurements. The comparison of LVD between peritumoral and intratumoral area revealed significantly higher PT-LVD (P = 0.001). No significant association was seen between LVD, IT-LVD and PT-LVD and different age groups, gender, site of tumor, risk factors, size of tumor, tumor inflammation, pushing/infiltrating margin and stage of tumors. Significantly higher LVD, IT-LVD and PT-LVD was seen in association with lymph node metastasis. Both high intratumoral and peritumoral LVD were found significantly associated with the presence of lymph node metastasis, however lymphatic vessels were found to be significantly more numerous and larger in peritumoral areas as compared to intratumoral lymphatics. The specificity of D2-40 as a lymphatic endothelial marker was also confirmed. The results of our study support the possibility of using the determination of tumor lymphangiogenesis to identify patients of HNSCC who are at risk of developing the lymph node metastasis.

AB - Local treatment with corticosteroids results in side effects involving the upper respiratory tract including candidiasis, sore throat, and dysphonia. Although these effects are well known, they have not been evaluated using a histopathological approach. This study investigated the histopathological aspects of steroid-induced dysphonia. A total of 16 female Wistar albino rats were divided into two groups. The eight rats in the experimental group were given an inhaled dose of mometasone furoate daily for 4 weeks. The control group was kept at room temperature for 4 weeks. The vocal cords were evaluated histopathologically using hematoxylin and eosin staining. Both groups had typical epithelial lining and basal membranes. Inflammation differed between the two groups (P = 0.024). There were no differences in squamous metaplasia and hyperplasia (P = 0.302 and 0.302, respectively). This study revealed that inhaled corticosteroids inhibit mucosal immunity, and may result in reversible mucosal changes.

AB - The aim of this study was to investigate the possible role of cochlear outer hair cell function with TEOAE and DPOAE tests in patients with normal hearing and tinnitus. 25 tinnitus patients with normal hearing sensitivity selected as study group. Control group consist of 50 normal hearing subjects without tinnitus. All subjects had thresholds below 25 dBHL at frequencies 250-8,000 Hz, tympanogram type A and normal acoustic reflex thresholds. TEOAE were recorded with click stimulus at 80 dB SPL at 1,000, 2,000, 3,000 and 4000 Hz. DPOAE were measured at frequencies 1,000-8,000 Hz and intensity of L1 55 dB SPL and L2 65 dB SPL. Amplitude of DPOAE and TEOAE were decreased in all frequencies in study group. There was significant difference regarding prevalence abnormal TEOAE and DPOAE between study group and control group. There was relationship between dysfunction of outer hair cells and tinnitus in subjects with normal hearing. PMID- 29456955 TI - Increased Atherosclerosis Correlates with Subjective Tinnitus Severity. AB - The aim of the present study was to investigate whether increased intima media thickness was associated with the severity of subjective non-pulsatile tinnitus and hearing loss. Data of the patients who came to Otorhinolaryngology Department of Isparta Government Hospital with subjective non-pulsatile tinnitus complaint, between January 2012 and June 2013, were evaluated retrospectively. A total of 215 patients were included in the present study. Hearing tests, biochemical analysis, tinnitus handicap inventory (THI), visual analogue scale (VAS) and doppler ultrasonography results of the patients were reviewed and recorded. The patients were classified into two groups as those having an increased intima media thickness and those having a normal intima media thickness. The said groups were compared with respect to age, gender, THI, VAS, hearing test findings and lipid values. Moreover, THI and VAS groups were compared with respect to intima media thickness. In the group having increased intima-media thickness, THI and VAS average, frequency of hypertension, total cholesterol, low density lipoprotein and triglyceride averages and mean frequencies obtained by hearing test were significantly higher. Comparison of THI and VAS groups showed that intima-media thickness was significantly different between those having a mild tinnitus and those having a severe tinnitus. Increased intima-media thickness was associated with the severity of subjective non-pulsatile tinnitus and hearing loss. For this reason, the carotid system should be examined in subjective non pulsatile tinnitus patients.

AB - Juvenile angiofibroma is a rare, highly vascular, histologically benign but locally invasive tumour, affecting predominantly male adolescents. To describe our experience in diagnosis of angiofibroma and treatment by combined endoscopic and transpalatal route. We analysed a case series of 50 patients of nasopharyngeal angiofibroma in Fisch stages I and II who presented at our institute during a period of four years 2011-2014, their clinical presentation, their treatment by combined transpalatal and endoscopic approach, intraoperative and post operative course, complications and tumour recurrence. Patients were aged 8-26 years. All patients were treated surgically by combined approach endoscopic and transpalatal. The mean operation time was 90 min, and the mean bleeding volume was 300 ml. Only 8 % patients came with recurrence and only 10 % came with palatal perforation (fistula formation). With gratifying results we advocate this novel technique for the treatment of early to intermediate JNA.

AB - This questioner survey aimed about awareness of the Cone Beam Computed Tomography (CBCT) machine and its various clinical applications in ENT, among the ENT surgeons in the state of Odisha. 150 questioner forms on CBCT were distributed to the all the participating ENT surgeons at a state level ENT conference, out of which the response rate was 110. The participants were asked to answer 30 multiple choice questions, which were divided into 3 parts; general information on CBCT, general approach to CBCT and practice related to CBCT. The statistical analysis of the data collected was carried out by a Chi square test to compare the means at a significance level of P < 0.05. The response rate for this study was 73%. The mean age of the participant ENT surgeons was 47.9 (+/-19.2). Of the study population, 71.2% (89) did not ever advice CBCT in their practice. Only 33.9% (38) of the population believed that CBCT is more beneficial in the field of ENT. Only 25% (28) knew that CBCT requires lower radiation dose than conventional CT. 28.1% (31) of population believed that the spatial orientation is better in CBCT than CT. 62.5% (69) of the population did not knew that CBCT can be used in imaging sinusitis of dental origins. 75% (83) of the population did not knew that CBCT can be used in diagnosis of obstructive sleep apnoea and visualizing airway space. Only 18.8% (21) of the study population agreed that the CBCT has the potential to replace conventional CT in ENT imaging in future. In the conclusion, this study clearly showed that the number of ENT surgeons advising CBCT imaging in their practice is very less. The knowledge about various advantages and clinical applications of CBCT had been very limited. However, through continuing medical education and conducting various seminars and workshops on CBCT, imparting chapters on CBCT, in the undergraduate and post graduate curriculum will definitely help increase the awareness on CBCT among ENT fraternity. PMID- 29456958 TI - Etiology of Noise-Induced Hearing Loss (NIHL) and its Symptomatic Correlation with Audiometry Observations in Type II Diabetes. AB - Type II diabetic mellitus (DM) is a chronic metabolic disease that impairs normal insulin production and glucose transport to the liver and muscles. In the India, about 1-5% population suffer from diabetes or related complication. So there is need to cure this disease. DM chronic auditory complications may include spiral ganglia atrophy, degeneration of the vestibulocochlear nerve myelin sheath, reduction of the number of spiral lamina nerve fibres, and thickening of the capillary walls of the stria vascularis and small arteries. This study aims to know the incidence of common parameters, blood sugar levels, levels of lipids and the hearing thresholds of individuals. It is a Noise-Induced Hearing Loss research study featuring hearing impairment in transport workers diagnosed as type II diabetic. All individuals were interviewed by various questioners related to listening ability of subjects and underwent a physical examination, blood investigations and audiometry. Hearing impairment was more prevalent among adults with diabetes. Sensory neuron hearing loss is predominant in both study groups. Mixed Bilateral Hearing Loss showed significant p value in (>.001) by audiometry. The percentage of hearing loss in diabetes (ranges 5.3-28.1%) and in non diabetics (ranges 3.4-24.1%) and risk factors in diabetes (ranges 22.8-35.1%) over nondiabetics (ranges 17.2-20.1%) which is eye opener. The correlation between type II diabetes and hearing impairment was independent of known risk factors for hearing impairment, such as noise exposure, build-up wax, ototoxic medication, smoking, tobacco chewing etc. PMID- 29456959 TI - Bleomycin Sclerotherapy in Lymphangiomas of Head and Neck: Prospective Study of 8 Cases.

This is a prospective study of 8 patients diagnosed with lymphangioma of head and neck presenting to ENT department of Tata main Hospital from December 2014 to January 2017. They were clinically and radiologically evaluated and treated with intralesional injection of bleomycin diluted in normal saline. Complete resolution was seen in 62.5% (5/8) of patients, 25% (2/8) had good response while 12.5% (1/8) had a poor response. No major complications were noted apart from fever and inflammation. Intralesional bleomycin can be used as a primary modality of treatment. PMID- 29456960 TI - Evaluation and Customization of WHO Safety Checklist for Patient Safety in Otorhinolaryngology. AB - The WHO has designed a safe surgery checklist to enhance communication and awareness of patient safety during surgery and to minimise complications. WHO recommends that the check-list be evaluated and customised by end users as a tool to promote safe surgery. The aim of present study was to evaluate the impact of WHO safety checklist on patient safety awareness in otorhinolaryngology and to customise it for the speciality. A prospective structured questionnaire based study was done in ENT operating room for duration of 1 month each for cases, before and after implementation of safe surgery checklist. The feedback from respondents (surgeons, nurses and anaesthetists) was used to arrive at a customised checklist for otolaryngology as per WHO guidelines. The checklist significantly improved team member's awareness of patient's identity (from 17 to 86%) and each other's identity and roles (from 46 to 94%) and improved team communication (from 73 to 92%) in operation theatre. There was a significant improvement in preoperative check of equipment and critical events were discussed more frequently. The checklist could be effectively customised to suit otolaryngology needs as per WHO guidelines. The modified checklist needs to be validated by otolaryngology associations. We conclude from our study that the WHO Surgical safety check-list has a favourable impact on patient safety awareness, team-work and communication of operating team and can be customised for otolaryngology setting.

AB - Endoscopic surgery is now standard of care for different Endocrine Disorders; the endoscopic thyroid surgery is becoming more popular and different approaches has been practice by many thyroid surgeon worldwide. Trans-orovestibular approach, based on the principle of natural orifice transluminal surgery is truly scar free thyroid surgery and has minimal dissection. We are presenting here three cases of benign solitary thyroid nodule operated endoscopically through trans-oro vestibular approach in one male and two female patients. Described about the approach, challenges during surgery and outcome. These surgeries documented very few in literatures in live human patients. Transoral endoscopic thyroid surgery through vestibular approach is shortest and direct remote access approach.

PMID- 29456966 TI - Metabolic Profile of Oral Squamous Carcinoma Cell Lines Relies on a Higher Demand of Lipid Metabolism in Metastatic Cells. AB - Tumor cells are subjected to a broad range of selective pressures. As a result of the imposed stress, subpopulations of surviving cells exhibit individual biochemical phenotypes that reflect metabolic reprograming. The present work aimed at investigating metabolic parameters of cells displaying increasing degrees of metastatic potential. The metabolites present in cell extracts fraction of tongue fibroblasts and of cell lines derived from human tongue squamous cell carcinoma lineages displaying increasing metastatic potential (SCC9 ZsG, LN1 and LN2) were analyzed by 1H NMR (nuclear magnetic resonance) spectroscopy. Living, intact cells were also examined by the non-invasive method of fluorescence lifetime imaging microscopy (FLIM) based on the auto fluorescence of endogenous NADH. The cell lines reproducibly exhibited distinct metabolic profiles confirmed by Partial Least-Square Discriminant Analysis (PLS-DA) of the spectra. Measurement of endogenous free and bound NAD(P)H relative concentrations in the intact cell lines showed that ZsG and LN1 cells displayed high heterogeneity in the energy metabolism, indicating that the cells would oscillate between glycolysis and oxidative metabolism depending on the microenvironment's composition. However, LN2 cells appeared to have more contributions to the oxidative status, displaying a lower NAD(P)H free/bound ratio. Functional experiments of energy metabolism, mitochondrial physiology, and proliferation assays revealed that all lineages exhibited similar energy features, although resorting to different bioenergetics strategies to face metabolic demands. These differentiated functions may also promote metastasis. We propose that lipid metabolism is related to the increased invasiveness as a result of the accumulation of malonate, methyl malonic acid, n-acetyl and unsaturated fatty acids (CH2)n in parallel with the metastatic potential progression, thus suggesting that the NAD(P)H reflected the lipid catabolic/anabolic pathways. PMID- 29456968 TI - Alternative Splicing of Differentiated Myeloid Cell Transcripts after Infection by Anaplasma phagocytophilum Impacts a Selective Group of Cellular Programs. AB - Eukaryotic proteome diversity exceeds that encoded within individual genes, and results in part from alternative splicing events of pre-messenger RNA. The diversity of these splicing events can shape the outcome in development and differentiation of normal tissues, and is important in pathogenic circumstances such as cancer and some heritable conditions. A role for alternative splicing of eukaryotic genes in response to viral and intracellular bacterial infections has only recently been recognized, and plays an important role in providing fitness for microbial survival, while potentially enhancing pathogenicity. Anaplasma phagocytophilum survives within mammalian neutrophils by reshaping transcriptional programs that govern cellular functions. We applied next generation RNAseq to ATRA-differentiated HL-60 cells established to possess transcriptional and functional responses similar to A. phagocytophilum-infected human neutrophils. This demonstrated an increase in transcripts with infection and high proportion of alternatively spliced transcript events (ASEs) for which predicted gene ontology processes were in part distinct from those identified by evaluation of single transcripts or gene-level analyses alone. The alternative isoforms are not on average shorter, and no alternative splicing in genes encoding spliceosome components is noted. Although not evident at gene-level analyses, individual spliceosome transcripts that impact nearly all spliceosome components were significantly upregulated. How the distinct GO processes predicted by ASEs are regulated by infection and whether they are relevant to fitness or pathogenicity of A. phagocytophilum should be addressed in more detailed studies. PMID- 29456969 TI - Mutation of Agr Is Associated with the Adaptation of Staphylococcus aureus to the Host during Chronic Osteomyelitis. AB - Selection pressures exerted on Staphylococcus aureus by host factors may lead to the emergence of mutants better adapted to the evolving conditions at the infection site. This study was aimed at identifying the changes that occur in S. aureus exposed to the host defense mechanisms during chronic osteomyelitis and evaluating whether these changes affect the virulence of the organism. Genome assessment of two S. aureus isolates collected 13 months apart (HU-85a and HU 85c) from a host with chronic osteomyelitis was made by whole genome sequencing. Agr functionality was assessed by qRT-PCR. Isolates were tested in a rat model of osteomyelitis and the bacterial load (CFU/tibia) and the morphometric osteomyelitic index (OI) were determined. The ability of the isolates to trigger the release of proinflammatory cytokines was determined on macrophages in culture. Persistence of S. aureus within the host resulted in an agrC frameshift mutation that likely led to the observed phenotype. The capacity to cause bone tissue damage and trigger proinflammatory cytokines by macrophages of the agr deficient, unencapsulated derivative (HU-85c) was decreased when compared with those of the isogenic CP8-capsulated parental strain (HU-85a). By comparison, no significant differences were found in the bacterial load or the OI from rats challenged with isogenic Reynolds strains [CP5, CP8, and non-typeable (NT)], indicating that lack of CP expression alone was not likely responsible for the reduced capacity to cause tissue damage in HU-85c compared with HU-85a. The production of biofilm was significantly increased in the isogenic derivative HU 85c. Lack of agr-dependent factors makes S. aureus less virulent during chronic osteomyelitis and alteration of the agr functionality seems to permit better adaptation of S. aureus to the chronically infected host. PMID- 29456970 TI - The Complement Binding and Inhibitory Protein CbiA of Borrelia miyamotoi Degrades Extracellular Matrix Components by Interacting with Plasmin(ogen). AB - The emerging relapsing fever spirochete Borrelia (B.) miyamotoi is transmitted by ixodid ticks and causes the so-called hard tick-borne relapsing fever or B. miyamotoi disease (BMD). More recently, we identified a surface-exposed molecule, CbiA exhibiting complement binding and inhibitory capacity and rendering spirochetes resistant to complement-mediated lysis. To gain deeper insight into the molecular principles of B. miyamotoi-host interaction, we examined CbiA as a plasmin(ogen) receptor that enables B. miyamotoi to interact with the serine protease plasmin(ogen). Recombinant CbiA was able to bind plasminogen in a dose dependent fashion. Moreover, lysine residues appear to play a crucial role in the protein-protein interaction as binding of plasminogen was inhibited by the lysine analog tranexamic acid as well as increasing ionic strength. Of relevance, plasminogen bound to CbiA can be converted by urokinase-type plasminogen activator (uPa) to active plasmin which cleaved both, the chromogenic substrate S 2251 and its physiologic substrate fibrinogen. Concerning the involvement of specific amino acids in the interaction with plasminogen, lysine residues located at the C-terminus are frequently involved in the binding as reported for various other plasminogen-interacting proteins of Lyme disease spirochetes. Lysine residues located within the C-terminal domain were substituted with alanine to generate single, double, triple, and quadruple point mutants. However, binding of plasminogen to the mutated CbiA proteins was not affected, suggesting that lysine residues distant from the C-terminus might be involved in the interaction. PMID- 29456971 TI - Molecular, biochemical and kinetic analysis of a novel, thermostable lipase (LipSm) from Stenotrophomonas maltophilia Psi-1, the first member of a new bacterial lipase family (XVIII). AB - Background: Microbial lipases catalyze a broad spectrum of reactions and are enzymes of considerable biotechnological interest. The focus of this study was the isolation of new lipase genes, intending to discover novel lipases whose products bear interesting biochemical and structural features and may have a potential to act as valuable biocatalysts in industrial applications. Results: A novel lipase gene (lipSm), from a new environmental Stenotrophomonas maltophilia strain, Psi-1, originating from a sludge sample from Psittaleia (Greece), was cloned and sequenced. lipSm was further overexpressed in E. coli BL21(DE3) and the overproduced enzyme LipSm was purified and analyzed in respect to its biochemical and kinetic properties. In silico analysis of LipSm revealed that it is taxonomically related to several uncharacterized lipases from different genera, which constitute a unique clade, markedly different from all other previously described bacterial lipase families. All members of this clade displayed identical, conserved consensus sequence motifs, i.e. the catalytic triad (S, D, H), and an unusual, amongst bacterial lipases, Y-type oxyanion hole. 3D-modeling revealed the presence of a lid domain structure, which allows LipSm to act on small ester substrates without interfacial activation. In addition, the high percentage of alanine residues along with the occurrence of the AXXXA motif nine times in LipSm suggest that it is a thermostable lipase, a feature verified experimentally, since LipSm was still active after heating at 70 degrees C for 30 min. Conclusions: The phylogenetic analysis of LipSm suggests the establishment of a new bacterial lipase family (XVIII) with LipSm being its first characterized member. Furthermore, LipSm is alkaliphilic, thermostable and lacks the requirement for interfacial activation, when small substrates are used. These properties make LipSm a potential advantageous biocatalyst in industry and biotechnology. PMID- 29456972 TI - The Effect of Levothyroxine and Selenium versus Levothyroxine Alone on Reducing the Level of Anti-thyroid Peroxidase Antibody in Autoimmune Hypothyroid Patients. AB - Background: Due to the prevalence of autoimmune hypothyroidism and its effects on physical and mental health it is necessary to provide a treatment which is also effective in preventing the progression of sub-clinical hypothyroidism in these patients. This study aims to investigate the effect of selenium supplementation on of anti-thyroid hormone antibodies in these patients. Materials and Methods: In a randomized clinical trial, 70 patients with autoimmune hypothyroidism randomly divided into two groups of 35 each, the first group was treated with oral selenium treatment with levothyroxine (LT4) and to the second group along with LT4, placebo was also prescribed. Serum selenium level, thyroid hormones and anti-thyroid hormone antibodies before and after 3 months of treatment in both groups, were determined, and the results were analyzed using SPSS software. Results: The mean of the serum anti-thyroid peroxidase serum level in the intervention group before and after treatment was 682.18 +/- 87.25 and 522.96 +/- 47.21 and the difference before and after treatment was statistically significant (P = 0.021). The level of this antibody before and after treatment in the control group was 441 +/- 53.54 and 501.18 +/- 77.68, and no significant differences between two groups were observed before and after treatment (P = 0.42). Conclusion: Selenium supplementation may help to reduce the levels of antibodies in patients with autoimmune hypothyroidism. PMID- 29456973 TI - Preventive Effects of Pre- and Intra-operative Marcaine, Lidocaine, and Marcaine Plus Lidocaine on Pain Relief in Lumbar Disc Herination Open Surgery. AB - Background: As marcaine is administered to a great extent due to minor complications and reasonable expenses and as discectomy is prevalently used in Iran, this study makes a comparison between effect of marcaine alone, lidocaine alone, and marcaine plus lidocaine on pain relief of patients undergoing lumbar disc open surgery. Materials and Methods: In a clinical trial study, 192 patients were selected and randomly divided into four groups. Patients in Groups 1-4 received 0.5 ml marcaine during surgery, 5 ml lidocaine 2% before incision, 5 ml lidocaine 2% before incision plus 5 ml marcaine during surgey and normal saline, respectively. After patients gained knowledge of visual analog scale (VAS) criteria, their severity of pain was measured and was recorded in their profiles, along with demographic details and history of diseases. After surgery and their transfer to their rooms, their severity of pain was measured and recorded again by using VAS criteria. Finally, difference between the four groups was compared by SPSS software. Results: The mean (+/-standard deviation) of postoperative pain in marcaine + lidocaine, marcaine, lidocaine, and normal saline was 3.5 +/- 1.3, 3.5 +/- 1.6, 36.1.9, and 4.2 +/- 1.8, respectively, and we did not observe any significant difference in severity of pain after surgery in these groups (P = 0.15). The highest and lowest degree of satisfaction occurred in marcaine lidocaine group and control group, respectively, (40 patients [83.3%] vs. 25 patients [52.1%]). Conclusion: Lidocaine-marcaine treatment reduces the need to opiates in cases of postoperative pain relief of discectomy and provides patients with great satisfaction. PMID- 29456974 TI - Evaluation of Outcomes of Open Reduction and Internal Fixation Surgery in Patients with Type C Distal Humeral Fractures. AB - Background: In this study, functional state of patients with Type C distal humerus fractures undergone surgical plating was evaluated 6 and 12 months after the surgery in order to record postsurgical factors such as pain level and job/performance satisfaction. Materials and Methods: In this cross-sectional study, 46 patients with humerus fractures were recruited and their ability to do daily tasks, presence of degenerative changes, stability of elbow joint, and range of motion was evaluated. For assessment of response to surgery, Mayo score was used. Results: Among 46 patients, 45 (97.8%) of them had joint stability. Evaluation of postsurgical complications showed that six subjects (13%) had no complications, but superficial infection was observed in 12 (26.1%) subjects. Neuromuscular disorders in ulnar nerve were present in 11 subjects (23.9%), recurrent articular bursitis of elbow joint in 6 subjects (13%), stiffness of elbow joint in 29 subjects (63%), nonunion of fracture in 3 subjects (6.5%), and myositis ossification in 4 (8.7%) subjects. Furthermore, 18 (39.1%) patients presented with more than one (2-4) complications. Conclusion: Open reduction and internal fixation surgery with dual plating is the method of choice for treatment of Type C distal humeral fractures. Evaluation of long-term outcomes of this surgery could be done via several different questionnaires as many studies suggest. This study demonstrated that the outcomes of this surgery in Isfahan, Iran, have been noticeably inferior compared to results of the studies in other parts of the world. PMID- 29456976 TI - Respiratory Viruses in Febrile Neutropenic Patients with Respiratory Symptoms. AB - Background: Respiratory infections are a frequent cause of fever in neutropenic patients, whereas respiratory viral infections are not frequently considered as a diagnosis, which causes high morbidity and mortality in these patients. Materials and Methods: This prospective study was performed on 36 patients with neutropenia who admitted to hospital were eligible for inclusion with fever (single temperature of >38.3 degrees C or a sustained temperature of >38 degrees C for more than 1 h), upper and lower respiratory symptoms. Sampling was performed from the throat of the patient by the sterile swab. All materials were analyzed by quantitative real-time multiplex polymerase chain reaction covering the following viruses; influenza, parainfluenza virus (PIV), rhinovirus (RV), human metapneumovirus, and respiratory syncytial virus (RSV). Results: RV was the most frequently detected virus and then RSV was the most. PIV was not present in any of the tested samples. Furthermore, no substantial differences in the distribution of specific viral species were observed based on age, sex, neutropenia duration, hematological disorder, and respiratory tract symptoms and signs (P > 0.05). Conclusion: Our prospective study supports the hypothesis that respiratory viruses play an important role in the development of neutropenic fever, and thus has the potential to individualize infection treatment and to reduce the extensive use of antibiotics in immunocompromised patients with neutropenia.

The current study aimed to compare Blacks and Whites on the association between SRH and mortality due to kidney diseases. A nationally representative sample of adults in the United States was used to provide generalizable results to the United States population. Materials and Methods: The Americans' Changing Lives study is a nationally representative cohort, conducted from 1986-2011. The study followed 3361 Blacks (n = 1156) and Whites (n = 2205) for up to 25 years. The outcome was time to death due to kidney diseases, derived from death certificates and the National Death Index. Cox proportional hazards models were used to test whether race and baseline SRH interact on mortality due to kidney diseases. Results: In the pooled sample, poor SRH (odds ratio [OR] = 2.29, 95% confidence interval [CI] = 1.24-4.24) was associated with an increased risk of death due to kidney diseases over the follow-up period. Baseline SRH also showed a significant interaction with race on the outcome (OR = 0.49, 95% CI = 0.25-0.96), suggesting a stronger effect of SRH on deaths due to kidney diseases for Whites compared to Blacks. In race-specific models, poor SRH at baseline increased risk of death due to kidney diseases among Whites (OR = 2.23, 95% CI = 1.14-4.34) but not Blacks (OR = 1.14, 95% CI = 0.54-2.41). Conclusions: Blacks and Whites differ regarding the predictive role of baseline SRH on death due to kidney diseases over time. Factors such as SRH better predict risk of mortality for Whites than for Blacks.

AB - Background: Cerebral aneurysms are a kind of cardiovascular diseases which are accompanied with high morbidity and mortality due to rupturing and causing subarachnoid hemorrhages. The current study aimed to determine epidemiologic and demographic features and prognosis of patients with cerebral aneurysms. Materials and Methods: In this cross-sectional study, 465 patients with cerebral aneurysms hospitalized in Al-Zahra Hospital were studied. The required information including demographic, epidemiologic, and clinical features of the disease were extracted from their records. The obtained data were analyzed using SPSS software and the factors associated with the prognosis of the disease were determined. Results: Four hundred and sixty-five cases with cerebral aneurysm undergoing surgery were investigated. The mean age of the patients was 48 +/- 14 years whereas 216 cases (46.5%) were male and 249 (53.5%) were female. Two hundred and thirty-seven patients (51%) remitted completely while the disease caused moderate disability in 84 cases (18.1%), severe disability in 24 ones (5.2%) and vegetative state in 9 cases (1.9%) and mortality in 57 ones while it was unknown in 54 cases (11.6%). In terms of the age of patient, WFNS index, anatomical position of aneurysm, type of aneurysm lesion, the incidence season of the disease, type of postoperative complications, family history and operative approach, the disease outcome had a significant difference while gender, ethnicity, and risk factors had no significant effect on the disease outcome. Conclusions: According to the type of aneurysm, the incidence position of the aneurysm and other epidemiologic, demographic, and clinical features, providing the prevention and treatment strategies is necessary. PMID- 29456978 TI - A Case of Tyrosinemia Type III with Status Epilepticus and Mental Retardation. AB - Tyrosinemia type III is an autosomal recessive disorder caused by the deficiency of 4- hydroxyphenylpyruvate dioxygenase (4-HPPD). It is characterized by elevated levels of blood tyrosine and massive excretion of its derivatives into the urine. Clinical findings of tyrosinemia type III include neurological symptoms and mental retardation. Only a few patients presenting with this disease have been described, and the clinical phenotype remains variable and unclear. We present a case, who was admitted to the hospital at the age of 4 months for recurrent seizures. Two months later, she was admitted again with status epilepticus. Laboratory data showed increased level of tyrosine in the blood. She was treated with a diet low in tyrosine and phenylalanine and anamix formula that leading to catch-up growth and improvement of her symptoms. Plasma tyrosine level dropped to normal values. In any child who presents with the neurologic symptom, some rare diagnosis like tyrosinemia type III should be considered. PMID- 29456979 TI - Quercetin Prevents Body Weight Loss Due to the Using of Superparamagnetic Iron Oxide Nanoparticles in Rat. AB - Background: Superparamagnetic iron oxide nanoparticles (SPION) have been largely considered for numerous applications in biomedicine such as magnetic resonance imaging, hyperthermia, cell tracking, anticancer treatment, and targeted delivery of drugs or genes. However, they may have side effects such body weight loss. Quercetin (QT), a strong antioxidant and free radical scavenger and a natural flavonoid, has a wide range of biological and therapeutic effects. In this study, the effect of QT on prevention of weight loss due to the using of SPION has been investigated. Materials and Methods: SPION and QT-SPION were administered orally at 50 and 100 mg/kg for 7 days. Then, the body weight was measured at the beginning and the end of the study. Results: Rats fed with 50 and 100 mg/kg SPION showed a significant weight loss, whereas those that fed with 50 mg/kg QT-SPION did not. A weight loss was observed in rats treated with 100 mg/kg of QT-SPION. Conclusions: The results of this study showed that quercetin could prevent weight loss due to the SPION. PMID- 29456980 TI - Effect of Patellar Electrocautery Neurectomy on Postoperative Pain among Patients Referred for Total Knee Arthroplasty. AB - Background: Anterior knee pain is a major problem in total knee arthroplasty (TKA). It is accepted that anterior knee pain (AKP) often contributes to a patellofemoral etiology; however, its etiology or treatment is not understood completely. Disabling pain receptors by electrocautery could theoretically lead to anterior knee area denervation. The present study aimed to evaluate the pain post-patellar denervation (PD) with electrocautery in TKA. Materials and Methods: Clinical results for 92 patients who underwent TKA (58 women, 34 men; mean age 67.5 years) were analyzed. In addition to removal of all osteophytes, PD by electrocautery was performed on patella of treatment group (n = 46) and debridement alone including removing of all osteophytes was performed on the control group (n = 46). Knee Society System (KSS) score, patella score (PS), and visual analog scale (VAS) were used to determine pre- and post-operative AKP. Results: The follow-up duration was 10 months. No revision or reoperations were performed. There were no patellar fractures. On all parameters (KSS score, PS, and VAS), there was a statistically significant pre- to post-operative difference in favor of the denervation group only 3 weeks after operation; however, there was no statistically difference postoperation on other follow-ups (3, 6, and 10 months). Conclusions: PD with electrocautery could reduce AKP in TKA without patellar resurfacing only in a short-term period postoperation. PMID- 29456982 TI - Early Outcome of Patient with Ulcerative Colitis who Received High Dose of Steroid and Underwent Two Staged Total Proctocolectomy. AB - Background: Ulcerative colitis (UC) is an idiopathic inflammatory disorder. Currently, the final treatment is colectomy. The aim of this study was to investigate the outcomes of proctocolectomy in patients that used a high dose of prednisolone. Materials and Methods: Seventy-five patients presenting for surgical management of histopathologically proven UC. All patients were offered total proctocolectomy (TPC) with ileal pouch-anal anastomosis (IPAA). Patients were divided into two groups: low dose of steroids (Group A) and high dose of steroid (Group B) consumers. Data from these patients after 2 years were reviewed and analyzed. Results: From total patients, 34 of them were male and 34 ones were female and seven patients underwent laparatomy. Overall incontinence rate was 8.8%; dysplasia was 22%, pouchitis was 18.9% while mortality was nil. The length of hospital stay was 6.76 days in Group A and 9.21 days in Group B (P = 0.399). Leakage was observed in nine of the patients after surgery (P = 0.589). Fecal incontinence between two groups was not statistically different (P = 0.063). Conclusions: Laparoscopic TPC-IPAA is feasible in patients needing surgical management of UC. Preoperative treatment with high-dose corticosteroids is associated with an increased risk of complications and reoperations. PMID- 29456981 TI - Prevalence of CTX-M and TEM beta-lactamases in Klebsiella pneumoniae Isolates from Patients with Urinary Tract Infection, Al-Zahra Hospital, Isfahan, Iran. AB - Background: Extended-spectrum beta-lactamase (ESBL)-producing is a significant resistant mechanism to beta-lactams in Enterobacteriaceae, especially in Klebsiella pneumoniae. The main objectives of this study were to genetically characterize urinary clinical isolates of K. pneumoniae through the investigating of blaTEM, blaCTX-M and using molecular typing by Enterobacterial repetitive intergenic consensus polymerase chain reaction (ERIC-PCR) method. We also determined the frequency of antibiotic resistance of K. pneumoniae strains to characterize the beta-lactamases included. Materials and Methods: A cross sectional study was carried out to evaluate 98 strains of K. pneumoniae isolated from urine culture of outpatients referred to Al-Zahra Hospital, Isfahan, Iran. Antibiotic susceptibility testing was performed using Kirby-Bauer's method. Screening of ESBLs was carried out using double-disk screening test. PCR technique was performed to detect TEM and CTX-M genes. The total DNA of each strain was tested by ERIC-PCR. Results: In 98 K. pneumoniae studied clinical isolates, 25.5% were ESBL producing and 44.9% multidrug-resistant (MDR). From 25 ESBL isolates, 23 (92%) cases showed MDR phenotype. In ESBL producing isolates, 23 (92%) were blaCTX-M and 19 (76%) blaTEM positive. The antimicrobial drug susceptibilities of ESBL isolates indicated high resistant rates for cefotaxime and ceftazidime. All 25 ESBL producing isolates were resistant to cefotaxime. Complex patterns of fingerprints isolates showed that 36% of the isolates were belonged to the cluster no 5. Conclusion: This study revealed high antimicrobial resistance rates among ESBL isolates which can lead to various health difficulties. Epidemiological data collection from patients is recommended to develop the strategies to manage antibiotic resistance. PMID- 29456983 TI - The Role of Mas Receptor on Renal Hemodynamic Responses to Angiotensin 1-7 in Both Irreversible and Reversible Unilateral Ureteral Obstruction Rats. AB - Background: Unilateral ureteral obstruction (UUO) alters the expression of renin angiotensin system (RAS) components and angiotensin 1-7 (Ang 1-7) as a main arm of RAS is affected by UUO. The role of Mas receptor antagonist (A779) was examined in renal hemodynamic responses to Ang 1-7 in 3-day UUO and UUO removal (RUUO) in rats. Materials and Methods: Forty-five male Wistar rats were randomly divided into three groups of sham operated, UUO, and RUUO, while each group was divided into two subgroups treated with vehicle or A779. Renal blood flow (RBF) and renal vascular resistance (RVR) responses to graded Ang 1-7 infusion were measured at controlled renal perfusion pressure. Results: Mean arterial pressure response to Ang 1-7 was increased in vehicle-treated subgroup significantly (P < 0.05) when compared with A779-treated subgroup. However, such observation was not seen in UUO and RUUO rats. The graded Ang 1-7 infusion increased RBF and decreased RVR significantly in vehicle-treated rats (P < 0.005). Furthermore, a significant difference was found between vehicle and A779-treated subgroups in sham, UUO, and RUUO groups (P < 0.005). Conclusion: Ang 1-7 could alter the kidney hemodynamics responses in ureteral obstruction models. PMID- 29456984 TI - The Efficacy of Internet-based Cognitive Behavioral Therapy on the Anxiety Disorders among Adolescent Girls. AB - Background: The prevalence of anxiety disorders among children and adolescents are found to be approximately between 8-12 and 5-10, respectively, and the long lasting effects of such disorders can expose the sufferers to impairment and dysfunction in several areas of life the examples of which are poor educational performance, low self-esteem, and depression. The present study aims to evaluate the efficacy of internet-based, cognitive-behavioral therapy (ICBT) in treating the anxiety disorders among adolescent females. Materials and Methods: The sample included thirty girls aged between 10 and 18 years suffering from a variety of anxiety disorders, under pharmaceutical therapy and referred to clinics of child and adolescent psychiatry specialists in Isfahan. The sample was selected through diagnostic interviews by psychiatrists based on the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision; afterward, they were randomly assigned to either the experimental or the control groups. To evaluate the efficacy of an ICBT in reducing anxiety disorder symptoms, Screen for Child Anxiety Related Emotional Disorders questionnaire was administered among the patients both before and 4 weeks after the treatment. Results: The covariance analysis results aimed to compare the anxiety disorder score variations between the two groups which demonstrate the fact that anxiety disorder scores in these two groups differ from one another (P < 0.001). Conclusions: This study is comprised of two Conclusions.the significant reduction in the mean of anxiety disorders scores in the experimental group compared to those in control group can be indicative of the efficacy of ICBT. In addition the significant reduction in the average of anxiety disorders symptoms' scores according to the type of anxiety disorders in the experimental group, compared to those in control group, can be indicative of the efficacy of ICBT. PMID- 29456985 TI - Evaluation of miR-21 Inhibition and its Impact on Cancer Susceptibility Candidate 2 Long Noncoding RNA in Colorectal Cancer Cell Line. AB - Background: Both microRNAs (miRNAs) and long noncoding RNAs (lncRNAs) have been shown to have a critical role in the regulation of cellular processes such as cell growth and apoptosis, as well as cancer progression and metastasis. lncRNAs are aberrantly expressed in many diseases including cancer. Although it is well known that miRNAs can target a large number of protein-coding genes, little is known whether miRNAs can also target lncRNAs. In the present study, we determine whether miR-21 can regulate lncRNA cancer susceptibility candidate 2 (CASC2) in colorectal cancer. Materials and Methods: LS174T cells were transfected with locked nucleic acid (LNA)-anti-miR-21 and scrambled LNA for 24, 48 and 72 h. The expression of miR-21 and lncCASC2 was evaluated by quantitative reverse transcriptase polymerase chain reaction. Results: However, contrary to what we expected and reported by others, lncCASC2 quantity was significantly reduced in LNA treated LS174T cells compared to the scrambled treated and normal untreated cells (P < 0.05). Conclusion: The interaction of miRNA and lncRNA are not as simple as suggested by other reports. Moreover, it could be complex molecular mechanisms underlying the communication of various noncoding RNA elements. PMID- 29456986 TI - Extract from Teucrium polium L. Protects Rat Heart against Oxidative Stress Induced by Ischemic-reperfusion Injury. AB - Background: The deleterious effect of oxidative stress on myocardial ischemia reperfusion (I/R) has already been shown in previous studies. Since Teucrium polium has anti-oxidative and cardio-protective properties, the aim of this study was to investigate the effects of this plant on I/R injuries in the isolated rat heart. Materials and Methods: The myocardial I/R injury of rat was created by Langendorff retrograde perfusion technology. The heart was preperfused with Krebs Henseleit (K-H) solution containing T. polium extract for 20 min before 20 min global ischemia, and then the reperfusion with K-H bicarbonate buffer was conducted for 40 min. The left ventricular developed pressure and the maximum up/down rate of the left ventricular pressure (+/-dp/dtmax) were recorded by physiological recorder as the myocardial function. Lactate dehydrogenase (LDH) and creatine kinase (CK) activities in the effluent were measured to determine the myocardial injury degree. Thiobarbituric acid reactive substances (TBARS), total thiol groups (-SH), superoxide anion dismutase (SOD), and catalase (CAT) in myocardial tissue were detected to determine the oxidative stress degree. Results: The results showed that the pretreatment with T. polium significantly enhanced cardiac parameters and the coronary artery flow, decreased the LDH, CK activities, and TBARS level, whereas it increased - SH groups, SOD and CAT activities. Conclusions: Our findings indicated that T. polium could provide protection for heart against the I/R injury which may be related to the improvement of myocardial oxidative stress states. PMID- 29456987 TI - Effects of Streptokinase and Normal Saline on the Incidence of Intra-abdominal Adhesion 1 Week and 1 Month after Laparotomy in Rats. AB - Background: Intra-abdominal adhesions after surgery are usually in the form of bands and can annoy the patient throughout life causing repeated surgical procedures. Therefore, any action to prevent adhesions after surgery can increase longevity and quality of life. For this aim, this study investigates the effect of streptokinase and normal saline on the 7th day and 1 month after laparotomy. Materials and Methods: Experimental study was conducted on thirty healthy male Wistar rats weighing 200-250 g with age of 3 months divided into three groups of 10. Group I: No treatment, Group II: Received normal saline, and Group III: Received normal saline and streptokinase at the same time. One week and 1 month after laparotomy, the frequency of the presence or absence of adhesion bands was performed by a person who was unaware of the sample grouping. The collected information was analyzed with the SPSS software (version 16; SPSS Inc., Chicago, IL, USA). Results: Adhesion frequency was found to be 20% on the 7th day (early) and 1 month after laparotomy (late) for Group 1, and it was 40% on early and late for Group II, while 0% on the early and late for Group III. Hence, in the group receiving streptokinase, no early or late adhesion was observed; therefore, it had a significant role in the prevention of intra-abdominal adhesions (P < 0.05). However, adhesions in the group receiving normal saline had no remarkable difference with the group receiving no drug (P > 0.05). Conclusion: According to the results of our study, we believe that streptokinase could be a good antiadhesive agent considering its effectiveness. PMID- 29456988 TI - Effect of Twine-arginine Translocation-signaling Fusion System and Chaperones Co expression on Secretory Expression of Somatropin. AB - Background: Twine-arginine translocation (TAT) system is one of the exporting systems in Escherichia coli which could transport fully/semi-correctly folded proteins outside the reductive cytoplasmic space. In combination with co expression with a chaperone system, the correctly folded proteins could be transported to oxidative periplasmic space and culture media to pass the main limitations in E. coli expression system such as misfolding and inclusion body formation. Materials and Methods: To study the effectiveness of signaling sequences and chaperone co-expression on the translocation of expressed protein, somatropin was selected as the target. Two common signal sequences in TAT system (TorA and SufI) were added at the N-terminal of somatropin and the cassettes were co-expressed in E. coli BL21 (DE3) by a chaperone team including DnaK/J-GrpeE. Results: The expression pattern studies including Western blotting and sodium dodecyl sulfate polyacrylamide gel electrophoresis confirmed that somatropin is expressed in two cassettes. However, the pattern was different for two signaling sequences. Conclusion: The results confirmed that the approach of using TAT signaling sequences and co-expression with the chaperone team could enhance translocation of protein to periplasmic space and culture media compared to control groups. Western blotting results showed that the signal sequence TorA could transport more expressed proteins to the periplasmic space and culture media in comparison with SufI. However, there was a considerable amount of human growth hormone in the cytoplasm which could not be transported outside the cytoplasmic space. PMID- 29456989 TI - Effect of Thymoquinone on Reproductive Parameter in Morphine-treated Male Mice. AB - Background: Thymoquinone as the main active component of Nigella sativa might have a various pharmacological effects such as antiapoptotic and antioxidant. Morphine is commonly used for the treatment of severe pain that can increase the generation of free radicals and affects the spermatogenesis. This study was designed to evaluate protective effects of thymoquinone against morphine-induced damages, sperm viability, count, motility, morphology and testis histology, and nitric oxide and testosterone hormone of the mice. Materials and Methods: In this experimental study, we divided 48 mice into eight groups (n = 6); various doses of thymoquinone (2, 10, and 20 mg/kg) and morphine (20 mg/kg) plus thymoquinone (2, 10, and 20 mg/kg) were administered intraperitoneally to 48 male mice for 30 consequent days. Male reproductive parameters including testis weight, testosterone hormone, serum nitric oxide, germinal thickness, sperm morphology, count, viability, and motility were analyzed and compared. Results: The results indicated that morphine administration significantly decreased germinal thickness, testis weight, testosterone level, viability, morphology, count, and motility of sperm and increased nitric oxide as compared to saline group (P < 0.05). However, increasing the dose of thymoquinone in the thymoquinone and thymoquinone plus morphine groups significantly decreases nitric oxide level (P < 0.05) while significantly boosted motility, morphology, count, viability of sperm cells, germinal thickness, and testosterone hormone in all groups as compared to morphine group (P < 0.05). Conclusion: It seems that thymoquinone administration could increase the quality some of spermatozoa and improves morphine-induced adverse effects on reproductive parameters in male mice. PMID- 29456990 TI - Ketamine versus Ketamine / magnesium Sulfate for Procedural Sedation and Analgesia in the Emergency Department: A Randomized Clinical Trial. AB - Background: The present study was designed to evaluate the effectiveness of magnesium sulfate (MgSO4) in procedural sedation and analgesia (PSA) when combined with ketamine in patients with fractures in emergency departments and required short and painful emergency procedures. Materials and Methods: In this study, 100 patients with fractures and dislocations who were presented to the emergency departments and required PSA for short and painful emergency procedures were randomly allocated to groups of ketamine plus MgSO4 or ketamine alone. Train of four (TOF) stimulation pattern was assessed using nerve stimulator machine and compared between groups. Results: The mean age of studied patients was 46.9 +/- 9.3 years old. 48% were male and 52% were female. No significant differences were noted between groups in demographic variables. The status of TOF, 2 min after the injection of ketamine (1.5 mg/kg), in both groups was similar. After the injection of the second dose of ketamine (1 mg/kg) the status of TOF in four patients in ketamine plus MgSO4 (0.45 mg/kg) group changed, it was three quarters but in ketamine group, the status of TOF in all patients was four quarters. The difference between groups was not statistically significant (P = 0.12). Conclusion: The findings revealed that for muscle relaxation during medical procedures in the emergency department, ketamine in combination with MgSO4 with this dose was not effective for muscle relaxation during procedures. PMID- 29456991 TI - Estimation and Projection of Prevalence of Colorectal Cancer in Iran, 2015-2020. AB - Background: Population aging and more prevalent westernized lifestyle would be expected to result in a markedly rising burden of colorectal cancer (CRC) in the future years. The aim of this study is to estimate the limited-time prevalence of CRC in Iran between 2015 and 2020. Materials and Methods: Aggregated CRC incidence data were extracted from the Iranian national cancer registry (IR.NCR) reports for 2003-2009 and from GLOBOCAN-2012 database for 2012. Incidence trends were analyzed by age groups, genders, histopathologic, and topographic subtypes to estimate annual percentage changes. Incidence was projected for 2020. The prevalence was estimated applying an adopted version of a previously introduced equation to estimate limited-time prevalence based on the incidence and survival data. Monte Carlo sensitivity analyses were applied to estimate 95% uncertainty levels (ULs). In each scenario, incidence, survival, annual percentage changes, and completeness of case ascertainment at IR.NCR were replaced under pre-assumed distributions. Results: Number of estimated within 1, 2-3 and 4-5-year CRC patients in 2015 were 13676 (95% UL: 10051-18807), 20964 (15835-28268), and 14485 (11188-19293), respectively. Estimated 5-year prevalence for 2020 (99463; 75150 134744) was 2.03 times of that for 2015. Highest 5-year prevalence was estimated in ages 55-59 for females and 75 + for males. Adenocarcinoma (41376; 31227 55898) was the most prevalent histologic subtype. The most prevalent tumor location was colon (30822, 23262-41638). Conclusion: A substantial growth in the prevalence of CRC survivors is highly expected for future years in Iran. Establishment of specialized institutes is highly recommended to provide medical and especially social supports for Iranian CRC survivors. PMID- 29456992 TI - National Immunization Campaigns with Oral Polio Vaccine Reduce All-Cause Mortality: A Natural Experiment within Seven Randomized Trials. AB - Background: A recent WHO review concluded that live BCG and measles vaccine (MV) may have beneficial non-specific effects (NSEs) reducing mortality from non targeted diseases. NSEs of oral polio vaccine (OPV) were not examined. If OPV vaccination campaigns reduce the mortality rate, it would suggest beneficial NSEs. Setting: Between 2002 and 2014, Guinea-Bissau had 15 general OPV campaigns and other campaigns with OPV plus vitamin A supplementation (VAS), VAS-only, MV, and H1N1 vaccine. In this period, we conducted seven randomized controlled trials (RCTs) with mortality as main outcome. Methods: Within these RCTs, we assessed whether the mortality rate was lower after-campaign than before-campaign. We used Cox models with age as underlying time and further adjusted for low birth-weight, season and time trend in mortality. We calculated the adjusted mortality rate ratio (MRR) for after-campaign vs before-campaign. Results: The mortality rate was lower after OPV-only campaigns than before, the MRR being 0.81 (95% CI = 0.68 0.95). With each additional dose of campaign-OPV the mortality rate declined further (MRR = 0.87 (95% CI: 0.79-0.96) per dose) (test for trend, p = 0.005). No other type of campaign had similar beneficial effects. Depending on initial age and with follow-up to 3 years of age, the number needed to treat with campaign OPV-only to save one life was between 68 and 230 children. Conclusion: Bissau had no case of polio infection so the results suggest that campaign-OPV has beneficial NSEs. Discontinuation of OPV-campaigns in low-income countries may affect general child mortality levels negatively. PMID- 29456993 TI - Measuring Adolescent Self-Awareness and Accuracy Using a Performance-Based Assessment and Parental Report. AB - Aim: The aim of this study was to assess awareness of performance and performance accuracy for a task that requires executive functions (EF), among healthy adolescents and to compare their performance to their parent's ratings. Method: Participants: 109 healthy adolescents (mean age 15.2 +/- 1.86 years) completed the Weekly Calendar Planning Activity (WCPA). The discrepancy between self estimated and actual performance was used to measure the level of awareness. The participants were divided into high and low accuracy groups according to the WCPA accuracy median score. The participants were also divided into high and low awareness groups. A comparison was conducted between groups using WCPA performance and parent ratings on the Behavior Rating Inventory of Executive Function (BRIEF). Results: Higher awareness was associated with better EF performance. Participants with high accuracy scores were more likely to show high awareness of performance as compared to participants with low accuracy scores. The high accuracy group had better parental ratings of EF, higher efficiency, followed more rules, and were more aware of their WCPA performance. Conclusion: Our results highlight the important contribution that self-awareness of performance may have on the individual's function. Assessing the level of awareness and providing metacognitive training techniques for those adolescents who are less aware, could support their performance. PMID- 29456994 TI - Benign Cutaneous Peripheral Nerve Sheath Tumor with Hybrid Features: Report of Two Cases with Schwannoma/Perineurioma and Schwannoma/Neurofibroma Components. AB - Hybrid benign peripheral nerve sheath tumors are rare tumors exhibiting areas of more than one neural neoplasm such as schwannoma/neurofibroma, neurofibroma/perineurioma, or schwannoma/perineurioma. These tumors usually arise in the skin of the extremities and trunk, and less commonly affect extracutaneous sites. Here we report two cases of these tumors exhibiting hybrid features of schwannoma/perineurioma and schwannoma/neurofibroma located in the scalp and the ankle, respectively. PMID- 29456995 TI - A 25-Year-Old Male with Orogenital Ulcers, Rash, and Difficulty Swallowing. AB - A 25-year-old otherwise healthy male presented with new-onset odynophagia, rash, and orogenital ulcers. Despite treatment with antibiotics for presumed bacterial pharyngitis, the patient remained symptomatic, with abnormal vital signs and laboratory values. Upon dermatology consultation and histopathologic correlation, he was diagnosed with Behcet disease. Behcet disease is a rare rheumatologic condition that presents with recurrent oral ulcers and varying degrees of ophthalmic, neurologic, cardiac, and vascular disease. Given its protean nature, the treatment of Behcet disease is tailored to the patient's presentation and severity of organ involvement. Following treatment with colchicine and prednisone, the patient's symptoms improved rapidly. PMID- 29456996 TI - A 65-Year-Old Male with Primary Central Nervous System Diffuse Large B-Cell Lymphoma on Nivolumab with Oral Mucositis and Targetoid Plaques. AB - Background/Aims: The development of programmed cell death-1 (PD-1) inhibitors has greatly improved patient outcomes in the treatment of a variety of advanced malignancies. These novel immunotherapies are not without adverse effects, the most common of which are dermatologic. Methods: We report our experience with an atypical erythema multiforme-like eruption in a patient with primary central nervous system diffuse large B-cell lymphoma treated with nivolumab. Results: The patient presented with oral mucositis and scattered erythematous papules which progressed to targetoid purpuric plaques with hyperkeratotic centers. Histopathology demonstrated interface dermatitis with dyskeratotic keratinocytes and pigment incontinence. The patient experienced improvement of the eruption with discontinuation of nivolumab and on systemic and topical glucocorticoids. Conclusion: As PD-1 inhibitors become more widely used in the treatment of advanced malignancies, the early recognition and treatment of rare dermatologic toxicities remain of great importance. PMID- 29456997 TI - A 71-Year-Old Female with Myocardial Infarction and Long-Standing Ulcers on the Thigh. AB - Calciphylaxis is most commonly encountered in patients with end-stage renal disease; however, it is increasingly observed in nonuremic patients as well. It is important to consider and diagnose nonuremic calciphylaxis early, as prompt treatment and mitigation of associated risk factors is essential to improve long term outcomes for these patients. Here, we present the case of a 71-year-old woman with atrial fibrillation on warfarin, but without renal disease, who presented with two long-standing ulcers on her thigh and was diagnosed with the aid of biopsy with calciphylaxis. We review the existing literature on the subject and offer this case as a representative report of a clinicopathologic correlation for this disorder. PMID- 29456998 TI - A 12-Month-Old Healthy Girl with a New Oral Ulcer and Chronic Diaper Rash. AB - A 12-month-old healthy girl presented with a chronic diaper rash. Physical examination demonstrated crusting of the scalp, erythematous papules with surrounding petechiae on the lower abdomen, and an intraoral palatal ulcer. Further imaging demonstrated bone involvement. Histopathologic examination of involved skin and the intraoral ulcer demonstrated epithelioid histiocytes with "coffee bean-shaped" nuclei, staining positive for CD1a and langerin by immunohistochemistry, consistent with Langerhans cell histiocytosis (LCH). LCH is a disease entity of unknown etiology characterized by histiocytic proliferation that most commonly presents in young children. The cutaneous findings of LCH include a seborrheic dermatitis-like and/or red-brown papular eruption. Intraoral examination is crucial as oral mucosal and maxillofacial skeletal disease can also be seen in LCH. When a child presents with a recalcitrant seborrheic dermatitis-like eruption or chronic diaper rash, the clinician should be alerted to the possibility of LCH. Timely recognition and diagnosis of LCH is important for oncologic referral, evaluation, and treatment. PMID- 29456999 TI - A 53-Year-Old Male with Relapsed Diffuse Large B-Cell Lymphoma on Chemotherapy with a New Leg Lesion. AB - Patients with underlying malignancy who develop new skin findings while acutely ill often require skin biopsy for histologic evaluation and/or culture to reach a diagnosis. Here, we present the case of a 53-year-old male with relapsed diffuse large B-cell lymphoma on chemotherapy who developed new skin lesions on the leg. On exam, there were 2 nickel-sized, erythematous to violaceous round plaques with central necrotic cores on the right lower leg with relatively nonspecific clinical features for which the initial differential diagnosis was broad. Consensus on a diagnosis was reached upon histologic evaluation of his skin biopsy in the context of his clinical setting. This diagnosis led to a change in treatment plan, with subsequent clinical improvement. PMID- 29457000 TI - Dysplastic Nevus: A Fake Lesion? PMID- 29457001 TI - Control of Infectious Diseases in the Era of European Clinical Microbiology Laboratory Consolidation: New Challenges and Opportunities for the Patient and for Public Health Surveillance. AB - Many new innovative diagnostic approaches have been made available during the last 10 years with major impact on patient care and public health surveillance. In parallel, to enhance the cost-effectiveness of the clinical microbiology laboratories (CMLs), European laboratory professionals have streamlined their organization leading to amalgamation of activities and restructuring of their professional relationships with clinicians and public health specialists. Through this consolidation process, an operational model has emerged that combines large centralized clinical laboratories performing most tests on one high-throughput analytical platform connected to several distal laboratories dealing locally with urgent analyses at near point of care. The centralization of diagnostic services over a large geographical region has given rise to the concept of regional-scale "microbiology laboratories network." Although the volume-driven cost savings associated with such laboratory networks seem self-evident, the consequence(s) for the quality of patient care and infectious disease surveillance and control remain less obvious. In this article, we describe the range of opportunities that the changing landscape of CMLs in Europe can contribute toward improving the quality of patient care but also the early detection and enhanced surveillance of public health threats caused by infectious diseases. The success of this transformation of health services is reliant on the appropriate preparation in terms of staff, skills, and processes that would be inclusive of stakeholders. In addition, rigorous metrics are needed to set out more concrete laboratory service performance objectives and assess the expected benefits to society in terms of saving lives and preventing diseases. PMID- 29457002 TI - Early Dietary Patterns and Microbiota Development: Still a Way to Go from Descriptive Interactions to Health-Relevant Solutions. AB - Early nutrition and growth in the initial years of life are important determinants of later body weight and metabolic health in humans, and the current epidemic of obesity involving children requires a better understanding of causal and protective mechanisms and components in infant foods. This review focuses on recent evidence implicating feeding modes (e.g., breast milk and formula milk) and dietary transitions toward complementary foods in the progression of microbiota maturation in children. The literature exploring body weight outcomes of microbiota changes induced by diet in early life is limited. Representative studies addressing the use of probiotics in pregnant women and infants are also examined. Methodological and geo-cultural variations make it difficult to avoid (apparently) controversial findings. Most studies indicate differences in the microbiota of formula versus breastfed infants, but some do not. Duration of breastfeeding delays the maturation of the microbiota toward an adult-like profile. However, the effect size of the early feeding pattern on microbial function was found to be very small, and absent after the third year of life. There are several interesting mediators whereby milk composition can affect infants' microbiota and their optimization is a desirable strategy for prevention. But prevention of what? Although there are few correlative evaluations relating microbiota and body weight in early life, studies demonstrating a cause-effect relationship between diet-induced changes in early microbiota development and subsequent metabolic health outcomes in humans are still missing.

AB - As health-care professionals, there often comes a time in our career when we are intrigued by the possibility of participating in humanitarian work in underserved countries. However, the desire to serve is often tempered by some ambivalence about whether our skill sets are applicable in less technologically advanced health-care settings. Furthermore, there may be some concern about the cultural and logistical challenges one might face while working overseas. A volunteer may also be worried that, despite their best intentions, the medical personnel in the host country will not take advantage of our knowledge and their patients will not achieve the best results. As a consequence, a talented and well-intentioned professional may decide not to volunteer, resulting in a lost opportunity to participate in what can be an extremely rewarding experience. I will be discussing a number of key factors that can strongly influence the quality of one's experience from the perspective of a Hand Specialist. My comments will primarily be a reflection of my personal experience over 20 years as a member of Health Volunteers Overseas (www.hvousa.org). PMID- 29457004 TI - The Molecular Bases of the Dual Regulation of Bacterial Iron Sulfur Cluster Biogenesis by CyaY and IscX. AB - IscX (or YfhJ) is a protein of unknown function which takes part in the iron sulfur cluster assembly machinery, a highly specialized and essential metabolic pathway. IscX binds to iron with low affinity and interacts with IscS, the desulfurase central to cluster assembly. Previous studies have suggested a competition between IscX and CyaY, the bacterial ortholog of frataxin, for the same binding surface of IscS. This competition could suggest a link between the two proteins with a functional significance. Using a hybrid approach based on nuclear magnetic resonance, small angle scattering and biochemical methods, we show here that IscX is a modulator of the inhibitory properties of CyaY: by competing for the same site on IscS, the presence of IscX rescues the rates of enzymatic cluster formation which are inhibited by CyaY. The effect is stronger at low iron concentrations, whereas it becomes negligible at high iron concentrations. These results strongly suggest the mechanism of the dual regulation of iron sulfur cluster assembly under the control of iron as the effector.

AB - Androgenetic alopecia (AGA) is a hair loss disorder affecting 80% of men and 50% of women throughout their lifetime. Therapies for AGA are limited and there is no cure. There is a high demand for hair restoration. Platelet-rich plasma (PRP), a treatment modality shown to promote wound healing, has also been explored as a treatment for AGA. This literature review was conducted to assess the effectiveness of PRP treatment for AGA. Twelve studies conducted from 2011 to 2017 were evaluated and summarized by study characteristics, mode of preparation, and treatment protocols. A total of 295 subjects were given PRP or control treatment in these studies, and evaluated for terminal hair density, hair quality, anagen/telogen hair ratio, keratinocyte proliferation, blood vessel density, etc. Some studies also provided subject self-assessment reports. Most of the studies reviewed showed effectiveness of PRP in increasing terminal hair density/diameter. Additional investigations are needed to determine the optimal treatment regimen for high efficacy of PRP in AGA. PMID- 29457007 TI - The Dermoscopic "Pluck Out Sign" for Beard Trichotillomania. AB - Beard trichotillomania (TTM) is a rather uncommon entity. Hair is not easily plucked from the beard area, as patients need forceps or tweezers to perform their task. The diagnosis of beard TTM can be quite tricky as the location is not the most frequent one. Dermoscopy might in these cases be helpful to achieve the correct diagnosis. In this article, we describe for the first time the "pluck out sign" for beard TTM. PMID- 29457008 TI - A Review of Platelet-Rich Plasma: History, Biology, Mechanism of Action, and Classification. AB - Platelet-rich plasma (PRP) is currently used in different medical fields. The interest in the application of PRP in dermatology has recently increased. It is being used in several different applications as in tissue regeneration, wound healing, scar revision, skin rejuvenating effects, and alopecia. PRP is a biological product defined as a portion of the plasma fraction of autologous blood with a platelet concentration above the baseline. It is obtained from the blood of patients collected before centrifugation. The knowledge of the biology, mechanism of action, and classification of the PRP should help clinicians better understand this new therapy and to easily sort and interpret the data available in the literature regarding PRP. In this review, we try to provide useful information for a better understanding of what should and should not be treated with PRP. PMID- 29457009 TI - Acneiform Rash Caused by an Unlikely Drug: Topiramate. AB - Topiramate is an antiepileptic drug that can also be used for migraine prophylaxis, weight control, and even for methamphetamine dependence; the dosage margin is wide, and the list of side effects is shorter than with other anticonvulsants. We present the case of a 35-year-old man with a disseminated rash of the trunk and extremities after treatment with 25 mg of topiramate daily as a prophylactic migraine treatment. This case report is useful, as this patient was not polymedicated and had a score of 7 on the Naranjo Adverse Drug Reaction Probability Scale. The patient was diagnosed as atypical DRESS syndrome and resolved satisfactorily with symptomatic treatment and topiramate withdrawal; slowly, the lesions regressed. He required no further drugs for the dermatologic condition. PMID- 29457010 TI - Telogen Effluvium: Is There a Need for a New Classification? A Reply.

AB - Linear scleroderma en coup de sabre (LSCS) is the most common form of morphea on the scalp and its trichoscopic features have not been described yet. We report 2 adult women with LSCS with distinct dermoscopic findings. They both had an atrophic well-defined linear patch of alopecia on the frontotemporal scalp. Dermoscopy showed loss of follicular openings on a whitish skin surface; scattered black dots, broken hairs, and pili torti; and short thick linear and branching tortuous vessels on the periphery of the lesion. Pathology confirmed the diagnosis of LSCS in the 2 cases. This description of dermoscopic features in LSCS on the scalp may help in the early diagnosis of the disease. PMID- 29457012 TI - Impact of Folliculitis Decalvans on Quality of Life and Subjective Perception of Disease. AB - Folliculitis decalvans (FD) is a primary neutrophilic scarring alopecia characterized by perifollicular papules, crusts, and pustules frequently located on the vertex. FD may affect young men and women. Since it may lead to hair loss, it can have a negative impact on patients' quality of life. Nevertheless, studies have focused on clinical, prognostic, and therapeutic aspects without considering the psychological impact of FD. In our study, we found that FD patients experienced a considerable impact on their quality of life. Interestingly, almost half of the patients considered that their alopecia was related to a poor medical care in their past. To our knowledge, this is the first description of the impact of FD on patients' quality of life, and it highlights the importance of psychological support for these patients.

AB - The trichoscopic features of frontal fibrosing alopecia (FFA) have been described in the frontotemporal area, yet there is no data detailing the trichoscopic features of the sideburns, which can be the initial or exclusive area of involvement. In this retrospective cohort study, 236 trichoscopic images of the frontotemporal and sideburn area obtained via dry trichoscopy from patients with biopsy-proven FFA were examined by two independent researchers to determine the trichoscopic features of FFA in the sideburns. The images of the sideburns were compared to 44 trichoscopic images of 11 healthy volunteers with intact sideburns. Transparent proximal hair emergence surrounded by patches of paler smooth skin was the most prominent finding in the sideburns. Peripilar casts and peripilar erythema were rare in the sideburns compared to the frontotemporal area. Although less common, transparent proximal hair emergence was also seen in the sideburns of healthy controls, yet it was shorter and restricted to individual hairs. Early FFA presenting exclusively or mostly with sideburn involvement should not be missed due to absence of peripilar casts and peripilar erythema. Dermoscopy-guided biopsy obtained from hair shafts with transparent proximal hair emergence should be considered to make the diagnosis in this location. PMID- 29457018 TI - Nail Changes in Early Mycosis Fungoides. AB - Background: Mycosis fungoides (MF) has a wide range of clinical presentations and it has been reported rarely to involve the nail apparatus. Objective: We intended to evaluate the frequency and characteristics of nail changes in patients with biopsy-proven MF. Methods: A retrospective analysis of 60 patients with MF who were evaluated at our cancer center from 2013 to 2014 was performed to identify patients with nail changes. Histological examinations of the skin around the nail apparatus were obtained from 10 patients with periungual skin erythema and scaling. Results: In 45 patients out of 60 cases, the skin around the nail apparatus was normal, and only in 5 patients of these 45 cases, nail changes were detected. These changes included leukonychia, longitudinal ridging, nail thickening, and opacity. In the remaining 15 patients, erythema and scaling was observed in periungual skin, and 13 of them demonstrated nail changes including longitudinal ridging, nail thickening, fragility of the nail plate, subungual hyperkeratosis, pigmented nail band, Beau's lines, onychomadesis, koilonychia, nail thinning, distal notching, subungual debris, leukonychia, and pitting. In biopsies of periungual skin, none of 10 cases revealed histological findings consistent with MF. Conclusions: Evidence of nail changes was observed in 18 cases (30%). The most common nail changes detected in MF patients included longitudinal ridging, nail thickening, nail fragility, and leukonychia.

AB - The risk of infective endocarditis in chronic hemodialysis patients is markedly higher than that in the general population. We report the first case of a hemodialysis patient with infective endocarditis caused by Streptococcus dysgalactiae subsp. equisimilis (SDSE) who presented with streptococcal toxic shock syndrome. In the last decade, there has been an increase in the incidence of SDSE infections. Therefore, it is important to recognize SDSE as a possible causative agent of infective endocarditis in an immunocompromised population, such as hemodialysis patients. PMID- 29457021 TI - Difficult Renal Pathological Classification in a Case of Pediatric Nephrotic Syndrome. AB - The underlying histopathology is very important in determining patient management, as the histopathology usually has direct repercussions on the treatment response and clinical course. However, the impact of the method used to assess renal biopsies, i.e., light microscopy (LM), immunofluorescence (IF), and electron microscopy (EM), on the occurrence of a difficult biopsy classification in the native kidneys of pediatric nephrotic patients is unknown. A 12-month-old Japanese boy was diagnosed with nephrotic syndrome (NS); he was administered prednisolone (60 mg/m2/day), and a continuous albumin infusion was started. A renal biopsy using LM revealed minimal change. However, an IF study showed granular staining for immunoglobulin G along the glomerular basement membrane. Therefore, he was diagnosed with membranous nephropathy (MN). As his proteinuria was so severe, we started immunosuppressant therapy and continued the albumin infusion for more than 2 months. However, he did not attain complete remission. A month later, EM examination of his renal biopsy showed extensive foot process fusion without electron-dense deposits. Although the result of the IF study suggested MN, the results of the LM and EM studies indicated minimal change. We finally diagnosed the patient with minimal change NS, in consideration of his clinical condition and course. Because of the failure of previous treatments, pulse steroid therapy was started. After five rounds of therapy the patient attained complete remission. A difficult renal biopsy finding classification, dependent on the diagnostic method used, might occur in the native kidneys of pediatric nephrotic patients. Therefore, a diagnosis should be made after considering all renal biopsy findings and the clinical course. PMID- 29457022 TI - A Case Report of Compound Heterozygous CYP24A1 Mutations Leading to Nephrolithiasis Successfully Treated with Ketoconazole. AB - CYP24A1 is an enzyme that inactivates vitamin D. Loss-of-function mutations in this enzyme are rare but have been linked with idiopathic infantile hypercalcemia as well as adult-onset nephrocalcinosis and nephrolithiasis. Genetic testing for this mutation should be considered in the presence of calciuria, elevated serum calcium, elevated 1,25-dihydroxyvitamin D, and suppressed parathyroid hormone. We present a case with these lab findings as well as an elevated 25-hydroxyvitamin D/24,25-dihydroxyvitamin D ratio in whom compound heterozygous CYP24A1 mutations were found. His hypercalciuria resolved and 1,25-vitamin D level improved with ketoconazole treatment. We suggest that it is clinically important to identify patients with this phenotype as testing and treatment options are available which could reduce progression to chronic kidney disease in this population. PMID- 29457023 TI - Effect of Zinc Supplementation on Maintenance Hemodialysis Patients: A Systematic Review and Meta-Analysis of 15 Randomized Controlled Trials. AB - We aimed to examine the effects of zinc supplementation on nutritional status, lipid profile, and antioxidant and anti-inflammatory therapies in maintenance hemodialysis (MHD) patients. We performed a systematic review and meta-analysis of randomized, controlled clinical trials of zinc supplementation. Metaregression analyses were utilized to determine the cause of discrepancy. Begg and Egger tests were performed to assess publication bias. Subgroup analysis was utilized to investigate the effects of zinc supplementation in certain conditions. In the crude pooled results, we found that zinc supplementation resulted in higher serum zinc levels (weighted mean difference [WMD] = 28.489; P < 0.001), higher dietary protein intake (WMD = 8.012; P < 0.001), higher superoxide dismutase levels (WMD = 357.568; P = 0.001), and lower levels of C-reactive protein (WMD = -8.618; P = 0.015) and malondialdehyde (WMD = -1.275; P < 0.001). The results showed no differences in lipid profile. In the metaregression analysis, we found that serum zinc levels correlated positively with intervention time (beta = 0.272; P = 0.042) and varied greatly by ethnicity (P = 0.023). Results from Begg and Egger tests showed that there was no significant bias in our meta-analysis (P > 0.1). Results of subgroup analysis supported the above results. Our analysis shows that zinc supplementation may benefit the nutritional status of MHD patients and show a time-effect relationship. PMID- 29457024 TI - Role of FGF23 in Pediatric Hypercalciuria. AB - Background: This study explored the possible role of FGF23 in pediatric hypercalciuria. Methods: Plasma FGF23 was measured in 29 controls and 58 children and adolescents with hypercalciuria: 24 before treatment (Pre-Treated) and 34 after 6 months of treatment (Treated). Hypercalciuric patients also measured serum PTH hormone, 25(OH)vitD, phosphate, calcium, creatinine, and 24 h urine calcium, phosphate, and creatinine. Results: There were no differences in age, gender, ethnicity, or body mass index either between controls and patients, or between Pre-Treated and Treated patients. Median plasma FGF23 in controls was 72 compared with all patients, 58 RU/mL (p = 0.0019). However, whereas FGF23 in Pre Treated patients, 73 RU/mL, was not different from controls, in Treated patients it was 50 RU/mL, significantly lower than in both controls (p < 0.0001) and Pre Treated patients (p = 0.02). In all patients, there was a correlation between FGF23 and urinary calcium (r = 0.325; p = 0.0014). Treated patients had significantly lower urinary calcium (p < 0.0001), higher TP/GFR (p < 0.001), and higher serum phosphate (p = 0.007) versus Pre-Treated patients. Conclusions: Pharmacological treatment of hypercalciuric patients resulted in significantly lower urinary calcium excretion, lower serum FGF23, and elevated TP/GFR and serum phosphate concentration, without significant changes in PTH. Further studies are indicated. This trial is registered with Clinical Registration Number RBR 8W27X5.

AB - The aim of our study was to investigate the influence of LPA gene polymorphisms for CAD risk and Lp(a) in a case-control study of Chinese Han population. In addition, we further analyzed the effect of LPA gene expression on plasma levels of Lp(a) and CAD risk. First, five SNPs (rs1367211, rs3127596, rs6415085, rs9347438, and rs9364559) in LPA gene were genotyped using the SEQUENOM Mass ARRAY system in two groups. Second, we used quantitative real-time PCR to examine the mRNA expression levels of LPA gene in 92 cases and 32 controls. Results showed that the frequency of rs6415085-T allele was significantly higher in case group than that in control group (P < 0.05). Haplotypes were not associated with CAD risk (P > 0.05). And cases with the TT/TG genotype had significantly higher plasma Lp(a) levels compared with those that have the rs6415085 GG genotype (P < 0.05). Additionally, the mRNA expression levels in case group are significantly higher than that in control group (P < 0.05). Our study confirmed that rs6415085 was associated with CAD and increased plasma Lp(a) levels. And increased mRNA expression level of LPA gene may be a mechanism in development of CAD. PMID- 29457026 TI - Antibiotic-Related Adverse Drug Reactions at a Tertiary Care Hospital in South Korea. AB - Background: Adverse drug reactions (ADRs) are any unwanted/uncomfortable effects from medication resulting in physical, mental, and functional injuries. Antibiotics account for up to 40.9% of ADRs and are associated with several serious outcomes. However, few reports on ADRs have evaluated only antimicrobial agents. In this study, we investigated antibiotic-related ADRs at a tertiary care hospital in South Korea. Methods: This is a retrospective cohort study that evaluated ADRs to antibiotics that were reported at a 2400-bed tertiary care hospital in 2015. ADRs reported by physicians, pharmacists, and nurses were reviewed. Clinical information reported ADRs, type of antibiotic, causality assessment, and complications were evaluated. Results: 1,277 (62.8%) patients were considered antibiotic-related ADRs based on the World Health Organization Uppsala Monitoring Center criteria (certain, 2.2%; probable, 35.7%; and possible, 62.1%). Totally, 44 (3.4%) patients experienced serious ADRs. Penicillin and quinolones were the most common drugs reported to induce ADRs (both 16.0%), followed by third-generation cephalosporins (14.9%). The most frequently experienced side effects were skin manifestations (45.1%) followed by gastrointestinal disorders (32.6%). Conclusion: Penicillin and quinolones are the most common causative antibiotics for ADRs and skin manifestations were the most frequently experienced symptom. PMID- 29457027 TI - Oxidative Modification of Biomolecules in the Nonstimulated and Stimulated Saliva of Patients with Morbid Obesity Treated with Bariatric Surgery. AB - Morbid obesity leads to progressive failure of many human organs and systems; however, the role of oxidative damage to salivary composition is still unknown in the obese patients. In this study, we assessed the effect of bariatric surgery on oxidative damage in nonstimulated (NS) and stimulated (S) whole saliva. The study included 47 subjects with morbid obesity as well as 47 age- and gender-matched healthy volunteers. Oxidative modifications to lipids (4-hydroxynonenal (4-HNE) and 8-isoprostanes (8-isoP)), proteins (advanced oxidation protein products (AOPP) and protein carbonyl groups (PC)), and DNA (8-hydroxy-D-guanosine (8 OHdG)) were analyzed in morbidly obese patients before and after bariatric surgery as well as in the healthy controls. The concentrations of 8-isoP, AOPP, PC, and 8-OHdG were significantly higher in both NS and S of patients with morbid obesity than in the control patients and compared to the results obtained 6 months after bariatric surgery. The levels of oxidative damage markers were also higher in S versus NS of morbidly obese patients. In summary, morbid obesity is associated with oxidative damage to salivary proteins, lipids, and DNA, while bariatric treatment generally lowers the levels of salivary oxidative damage. PMID- 29457028 TI - Effect of Dietary Chestnut or Quebracho Tannin Supplementation on Microbial Community and Fatty Acid Profile in the Rumen of Dairy Ewes. AB - Ruminants derived products have a prominent role in diets and economy worldwide; therefore, the capability to control the rumen microbial ecosystem, for ameliorating their quality, is of fundamental importance in the livestock sector. The aim of this study was to evaluate the effect of dietary supplementation with chestnut and quebracho tannins on microbial community and fatty acid profile, in the rumen fluid of dairy ewes. Multivariate analysis of PCR-DGGE profiles of rumen microbial communities showed a correlation among the presence of chestnut or quebracho in the diet, the specific Butyrivibrio group DGGE profiles, the increase in 18:3 cis9, cis12, and cis15; 18:2 cis9 and cis12; 18:2 cis9 and trans11; 18:2 trans11 and cis15; and 18:1 trans11 content, and the decrease in 18:0 concentration. Phylogenetic analysis of DGGE band sequences revealed the presence of bacteria representatives related to the genera Hungatella, Ruminococcus, and Eubacterium and unclassified Lachnospiraceae family members, suggesting that these taxa could be affected by tannins presence in the diets. The results of this study showed that tannins from chestnut and quebracho can reduce the biohydrogenation of unsaturated fatty acids through changes in rumen microbial communities. PMID- 29457029 TI - Preventive Effect of Cashew-Derived Protein Hydrolysate with High Fiber on Cerebral Ischemia. AB - This study aimed to determine the protective effect of cashew nut-derived protein hydrolysate with high dietary fiber (AO) in cerebral ischemic rats induced by the occlusion of right middle cerebral artery (Rt.MCAO). Acute toxicity was determined and data showed that LD50 of AO > 5000 mg/kg BW. To determine the cerebroprotective effect of AO, male Wistar rats were orally given AO at doses of 2, 10, and 50 mg/kg for 14 days and subjected to Rt.MCAO. Brain infarction volume, neurological score, spatial memory, serum lipid profiles, and C-reactive protein together with the brain oxidative stress status were assessed. All doses of AO significantly decreased brain infarction in cortex, hippocampus, and striatum together with the decreased oxidative stress status. The improvement of spatial memory and serum C-reactive protein were also observed in MCAO rats which received AO at all doses. In addition, the decreased serum cholesterol, TG, and LDL but increased HDL were observed in MCAO rats which received high dose of AO. Taken all together, AO is the potential protectant against cerebral ischemia. The improvement of oxidative stress, inflammation, and dyslipidemia might play roles in the actions. However, further researches are required to understand the precise underlying mechanism. PMID- 29457030 TI - The Relationship of Motor Coordination, Visual Perception, and Executive Function to the Development of 4-6-Year-Old Chinese Preschoolers' Visual Motor Integration Skills. AB - Visual motor integration (VMI) is a vital ability in childhood development, which is associated with the performance of many functional skills. By using the Beery Developmental Test Package and Executive Function Tasks, the present study explored the VMI development and its factors (visual perception, motor coordination, and executive function) among 151 Chinese preschoolers from 4 to 6 years. Results indicated that the VMI skills of children increased quickly at 4 years and peaked at 5 years and decreased at around 5 to 6 years. Motor coordination and cognitive flexibility were related to the VMI development of children from 4 to 6 years. Visual perception was associated with the VMI development at early 4 years and inhibitory control was also associated with it among 4-year-old and the beginning of 5-year-old children. Working memory had no impact on the VMI. In conclusion, the development of VMI skills among children in preschool was not stable but changed dynamically in this study. Meanwhile the factors of the VMI worked in different age range for preschoolers. These findings may give some guidance to researchers or health professionals on improving children's VMI skills in their early childhood.

AB - A prototype decision support IT-tool for the food industry was developed in the STARTEC project. Typical processes and decision steps were mapped using real life production scenarios of participating food companies manufacturing complex ready to-eat foods. Companies looked for a more integrated approach when making food safety decisions that would align with existing HACCP systems. The tool was designed with shelf life assessments and data on safety, quality, and costs, using a pasta salad meal as a case product. The process flow chart was used as starting point, with simulation options at each process step. Key parameters like pH, water activity, costs of ingredients and salaries, and default models for calculations of Listeria monocytogenes, quality scores, and vitamin C, were placed in an interactive database. Customization of the models and settings was possible on the user-interface. The simulation module outputs were provided as detailed curves or categorized as "good"; "sufficient"; or "corrective action needed" based on threshold limit values set by the user. Possible corrective actions were suggested by the system. The tool was tested and approved by end users based on selected ready-to-eat food products. Compared to other decision support tools, the STARTEC-tool is product-specific and multidisciplinary and includes interpretation and targeted recommendations for end-users. PMID- 29457033 TI - Measurement of Gender Differences of Gastrocnemius Muscle and Tendon Using Sonomyography during Calf Raises: A Pilot Study. AB - Skeletal muscles are essential to the gender-specific characteristics of human movements. Sonomyography, a new signal for quantifying muscle activation, is of great benefit to understand muscle function through monitoring the real-time muscle architectural changes. The purpose of this pilot study was to investigate gender differences in the architectural changes of gastronomies muscle and tendon by using sonomyography during performing two-legged calf raising exercises. A motion analysis system was developed to extract sonomyography from ultrasound images together with kinematic and kinetic measurements. Tiny fascicle length changes among seven male subjects were observed at the initial part of calf raising, whereas the fascicle of seven female subjects shortened immediately. This result suggested that men would generate higher mechanical power output of plantar flexors to regulate their heavier body mass. In addition, the larger regression coefficient between the fascicle length and muscle force for the male subjects implied that higher muscle stiffness for the men was required in demand of maintaining their heavier body economically. The findings from the current study suggested that the body mass might play a factor in the gender difference in structural changes of muscle and tendon during motion. The sonomyography may provide valuable information in the understanding of the gender difference in human movements.

Hence, this study examined the usefulness of a unilateral arm crank exercise test to assess cardiorespiratory fitness in individuals with stroke, including sixteen individuals with hemiparetic stroke (mean +/- SD age, 56.4 +/- 7.5 years) and 12 age- and sex-matched healthy controls. Participants performed the unilateral arm crank and leg cycle exercise tests to measure oxygen consumption ([Formula: see text]O2) and heart rate at peak exercise. The [Formula: see text]O2 at peak exercise during the unilateral arm crank exercise test was significantly lower in the stroke group than in the control group (p < 0.001). In the stroke group, the heart rate at peak exercise during the unilateral arm crank exercise test did not significantly correlate with the Brunnstrom recovery stages of the lower extremity (p = 0.137), whereas there was a significant correlation during the leg cycle exercise test (rho = 0.775, p < 0.001). The unilateral arm crank exercise test can detect the deterioration of cardiorespiratory fitness independently of lower extremity motor impairment severity in individuals with hemiparetic stroke. This study is registered with UMIN000014733. PMID- 29457035 TI - Impact of Elevated Circulating Histones on Systemic Inflammation after Radiofrequency Ablation in Lung Cancer Patients. AB - Background: This study investigated the changes of circulating histones following radiofrequency ablation (RFA) in lung cancer patients and their impact on systemic inflammation. Methods: Serial blood samples were obtained from a total of 65 primary and metastatic lung cancer patients undergoing RFA at 2 time points: pre-RFA and post-RFA within 48 h. Circulating histones, myeloperoxidase (MPO), and multiple inflammatory cytokines were measured. Moreover, the patient's sera were incubated overnight with human monocytic U937 cells in the presence or absence of anti-histone antibody, and cytokine production was evaluated. Results: Compared to pre-RFA, there was a significant increase in circulating histones within 48 h after RFA, along with an elevation of MPO and several canonical inflammatory cytokines. Circulating histones were correlated with these inflammatory markers. Notably, compared to the sera obtained before RFA, the patients' post-RFA sera significantly stimulated cytokine production in the supernatant of U937 cells, which could be prevented by anti-histone antibody, thereby confirming a cause-effect relationship between circulating histones and systemic inflammation. Conclusions: This study showed that circulating histones may serve as a marker indicating RFA-related systemic inflammation as well as represent a therapeutic target for resolution of inflammation. PMID- 29457036 TI - Zoledronic Acid Regulates Autophagy and Induces Apoptosis in Colon Cancer Cell Line CT26. AB - Zoledronic acid (ZOL) is the third generation of bisphosphonates, which can inhibit many tumors growth, especially to inhibit the growth of colon cancer. However, the molecular mechanism is still very mysterious. In this study, we observed that ZOL could regulate CT26 colon cancer cells autophagy, promote CT26 cells apoptosis, and inhibit CT26 cells proliferation. Western blotting analysis showed that proapoptosis protein caspase-3 was basically unchanged, whereas the expression of the activated caspase-3 was significantly increased, after CT26 cells were treated with different doses of zoledronic acid. Western blot also showed that ZOL could significantly affect the expression of p-p53 and autophagy related proteins beclin-1 and p62. In conclusion, the antitumor effect of ZOL on CT26 colon cancer cells in vitro is achieved by apoptosis induction and autophagy regulation, resulting in inhibition of cell proliferation. PMID- 29457037 TI - Decreased Expression of Semaphorin3A/Neuropilin-1 Signaling Axis in Apical Periodontitis. AB - Apical periodontitis (AP) is a chronic infection of endodontic origin accompanied with bone destruction around the apical region. Semaphorin3A (Sema3A) and neuropilin-1 (Nrp1) are regarded as a pair of immune regulators in bone metabolism. In this study, we firstly investigated the expression pattern of Sema3A/Nrp1 in apical periodontitis and its correlation with bone destruction. Using rat animal model, we analysed the level of mandibular bone destruction and the expression of Sema3A/Nrp1 on days 0, 7, 14, 21, 28, and 35 after pulp exposure. In addition, clinical samples from apical periodontitis patients were obtained to analyse the expression of Sema3A/Nrp1. These results indicated that the bone destruction level expanded from days 7 to 35. The number of positive cells and level of mRNA expression of Sema3A/Nrp1 were significantly decreased from days 7 to 35, with a negative correlation with bone destruction. Moreover, expression of Sema3A/Nrp1 in the AP group was reduced compared to the control group of clinical samples. In conclusion, decreased expression of Sema3A/Nrp1 was observed in periapical lesions and is potentially involved in the bone resorption of the periapical area, suggesting that Sema3A/Nrp1 may contribute to the pathological development of apical periodontitis. PMID- 29457038 TI - Insulin Resistance and Its Association with Metabolic Syndrome in Korean Children. AB - Background: This study investigated the association between insulin resistance (IR) and metabolic syndrome (MetS) in children. Methods: A cross-sectional study involving 1036 healthy children aged between 7 and 13 years was conducted. Homeostasis model assessment of insulin resistance (HOMA-IR) was calculated as an index of IR. Participants were classified according to the HOMA-IR quartiles. Results: Incremental, linear trends were found in age (p < 0.001), body mass index (BMI) (p < 0.001), body fat (p < 0.001), waist circumference (p < 0.001), resting blood pressures (BP) (p < 0.001), triglycerides (TG) (p < 0.001), total cholesterol (TC) (p < 0.001), high density lipoprotein-cholesterol (HDL-C) (p < 0.001), FBG (p < 0.001), and insulin (<0.001) according to incremental HOMA-IR categories (from the 1st to 4th quartile). Compared with children in the 1st HOMA IR quartile, children in the 4th HOMA-IR quartile had significantly higher odd ratios (ORs) of abnormalities in systolic (p = 0.051) and diastolic BP (p = 0.005), FBG (p < 0.001), TG (p < 0.001), TC (p = 0.016), and HDL-C (p = 0.006) even after adjustments for age, gender, BMI, and body fat percentage. Children in the 3rd HOMA-IR quartile had significant abnormalities in FBG (p < 0.001), TG (p = 0.001), and HDL-C (p = 0.010) even after adjustments for the covariates. Conclusion: The current findings suggest that IR is significantly associated with the clustering of MetS risk factors in children in Korea. PMID- 29457040 TI - A fluorescence assay for detecting amyloid-beta using the cytomegalovirus enhancer/promoter. AB - Robust assays for detecting the effects of elevated concentrations of amyloid beta (Abeta) may facilitate Alzheimer's disease research. An appropriate assay would be high-throughput and enable identification of drugs and genetic mutations that block the effects of Abeta, potentially leading to treatments for Alzheimer's disease. We discovered that the commonly used cytomegalovirus (CMV) enhancer/promoter is sensitive to the effects of Abeta. By combining the CMV enhancer/promoter with a fluorescent protein, we created a reporter system that produces changes in intracellular fluorescence in response to Abeta. Using hippocampal neurons, we quantified the ability of a CMV-fluorescent protein recombinant reporter to detect both exogenously applied and overexpressed Abeta. This is the first report of a high-throughput enhancer/promoter-based Abeta detection method. The reporter is able to detect the effects of elevated concentrations of Abeta in a high-throughput fashion, providing a new tool for Alzheimer's disease research and important knowledge about the commonly used CMV enhancer/promoter. PMID- 29457039 TI - Silencing Chitinase Genes Increases Susceptibility of Tetranychus cinnabarinus (Boisduval) to Scopoletin. AB - The carmine spider mite Tetranychus cinnabarinus is a major pest of crop and vegetable plants worldwide. Previous studies have shown that scopoletin is a promising acaricidal compound against Tetranychus cinnabarinus. However, the acaricidal mechanism of scopoletin remains unclear. In the present study, 12 full length cDNAs of chitinase (CHIT) genes from Tetranychus cinnabarinus (designated TcCHITs) were cloned and characterized. Although TcCHITs were expressed throughout all life stages, their expression levels were significantly upregulated during the larval and nymphal stages. TcCHITs were downregulated 24 h after treatment with scopoletin and upregulated 24 h after treatment with diflubenzuron (DFB, a chitin synthesis inhibitor). Feeding double-stranded RNA effectively silenced TcCHIT transcription in Tetranychus cinnabarinus, thus increasing its susceptibility to scopoletin but reducing that to DFB. Meanwhile, TcCHIT silencing in larvae and adult resulted in an extremely low molting rate (7.3%) and high mortality rate (53.3%), respectively, compared with those in the control group. CHIT genes are closely related to arthropod survival, molting, and development in Tetranychus cinnabarinus, suggesting that acaricidal mechanisms of scopoletin and DFB may occur by inhibition and activation of CHIT gene expression, respectively. TcCHIT constitutes a possible target of scopoletin and DFB in Tetranychus cinnabarinus. PMID- 29457041 TI - How to Catch a Smurf? - Ageing and Beyond... In vivo Assessment of Intestinal Permeability in Multiple Model Organisms. AB - The Smurf Assay (SA) was initially developed in the model organism Drosophila melanogaster where a dramatic increase of intestinal permeability has been shown to occur during aging (Rera et al., 2011). We have since validated the protocol in multiple other model organisms (Dambroise et al., 2016) and have utilized the assay to further our understanding of aging (Tricoire and Rera, 2015; Rera et al., 2018). The SA has now also been used by other labs to assess intestinal barrier permeability (Clark et al., 2015; Katzenberger et al., 2015; Barekat et al., 2016; Chakrabarti et al., 2016; Gelino et al., 2016). The SA in itself is simple; however, numerous small details can have a considerable impact on its experimental validity and subsequent interpretation. Here, we provide a detailed update on the SA technique and explain how to catch a Smurf while avoiding the most common experimental fallacies.

PMID- 29457044 TI - Once upon a Time a Guideline Was Used for the Evaluation of Suspected Choledocholithiasis: A Fairy Tale or a Nightmare? PMID- 29457045 TI - Efficacy of Endoscopic Retrograde Cholangiopancreatography in the Treatment of Biliary Complications following Liver Transplant: 10 Years of a Single-Centre Experience. AB - Background and Aims: Biliary tract complications following liver transplant remain an important source of morbidity and mortality. Endoscopic retrograde cholangiopancreatography (ERCP) has become a common therapeutic option before other invasive procedures. The aim of this study was to evaluate ERCP efficacy in managing this type of complications. Methods: Retrospective study of all patients who underwent therapeutic ERCP due to post-liver transplant biliary complications between September 2005 and September 2015, at a deceased donor liver transplantation centre. Results: Therapeutic ERCP was performed in 120 patients (64% men; mean age 46 +/- 14 years). Biliary complications were anastomotic strictures (AS) in 70%, non-anastomotic strictures (NAS) in 14%, bile leaks (BL) in 5.8%, and bile duct stones (BDS) in 32%. The mean time between liver transplant and first ERCP was: 19 +/- 30 months in AS, 17 +/- 30 months in NAS, 61 +/- 28 months in BDS, and 0.7 +/- 0.6 months in BL (p < 0.001). The number of ERCP performed per patient was: 3.8 +/- 2.4 in AS, 3.8 +/- 2.1 in NAS, 1.9 +/- 1 in BDS, and 1.9 +/- 0.5 in BL (p = 0.003). The duration of the treatment was: 18 +/- 19 months in AS, 21 +/- 17 months in NAS, 10 +/- 10 months in BDS, and 4 +/- 3 months in BL (p = 0.064). Overall, biliary complications were successfully managed by ERCP in 46% of cases, either as an isolated procedure (43%) or rendez vous ERCP (3%). Per complication, ERCP was effective in 39% of AS, in 12% of NAS, in 91% of BDS, and in 86% of BL. Globally, the mean follow-up of the successful cases was 43 +/- 31 months. Percutaneous transhepatic cholangiography and/or surgery were performed in 48% of patients in whom ERCP was unsuccessful. The odds ratio for effective endoscopic treatment was 0.2 for NAS (0.057-0.815), 12.4 for BDS (1.535-100.9), and 6.9 for BL (0.798-58.95). No statistical significance was found for AS (p = 0.247). Conclusions: ERCP allowed the treatment of biliary complication in about half of patients, avoiding a more invasive procedure. Endoscopic treatment was more effective for BDS and BL. PMID- 29457046 TI - Acute-on-Chronic Liver Failure: A Portuguese Single-Center Reference Review. AB - : Acute-on-chronic liver failure (ACLF) is a syndrome characterized by an acute deterioration of a patient with cirrhosis, frequently associated with multi-organ failure and a high short-term mortality rate. We present a retrospective study that aims to characterize the presentation, evolution, and outcome of patients diagnosed with ACLF at our center over the last 3 years, with a comparative analysis between the group of patients that had ACLF precipitated by infectious insults of bacterial origin and the group of those with ACLF triggered by a nonbacterial infectious insult; the incidence of acute kidney injury and its impact on the prognosis of ACLF was also analyzed. Twenty-nine patients were enrolled, the majority of them being male (89.6%), and the mean age was 53 years. Fourteen patients (48.3%) developed ACLF due to a bacterial infectious event, and 9 of them died (64.2%, overall mortality rate 31%); however, no statistical significance was found (p < 0.7). Of the remaining 15 patients (51.7%) with noninfectious triggers, 11 died (73.3%, overall mortality rate 37.9%); again there was no statistical significance (p < 0.7). Twenty-four patients (83%) developed acute kidney injury (overall mortality rate 65.5%; p < 0.022) at the 28 day and 90-day follow-up. Twelve patients had acute kidney injury requiring renal replacement therapy (41.37%; overall mortality rate 37.9%; p < 0.043). Hepatic transplant was performed in 3 patients, with a 100% survival at the 28-day and 90 day follow-up (p < 0.023). Higher grades of ACLF were associated with increased mortality (p < 0.02; overall mortality 69%). Conclusions: ACLF is a heterogeneous syndrome with a variety of precipitant factors and different grades of extrahepatic involvement. Most cases will have some degree of renal dysfunction, with an increased risk of mortality. Hepatic transplant is an efficient form of therapy for this syndrome. PMID- 29457047 TI - Performance of the Choledocholithiasis Diagnostic Score in Patients with Acute Cholecystitis. AB - Introduction: The prevalence of choledocholithiasis among patients with acute cholecystitis is estimated to be between 9 and 16.5%. There are no validated algorithms to predict choledocholithiasis in this group of patients. Aim: The aim of this study was to evaluate the performance of the choledocholithiasis diagnostic score proposed by the American Society for Gastrointestinal Endoscopy, in patients with acute cholecystitis. Material/Methods: A retrospective cross sectional study, covering a 4-year period at a secondary care hospital, was performed. All patients with an encoded diagnosis of acute cholecystitis and with at least one of the following procedures were included: endoscopic retrograde cholangiopancreatography (ERCP), endoscopic ultrasound, magnetic resonance cholangiopancreatography, and intraoperative cholangiography. Results: Among 4,369 patients with the diagnosis of acute cholecystitis, 40 (0.92%) had clinical or sonographic suspicion of choledocholithiasis. Their mean age was 68.1 +/- 15 years, and 22 (55%) were men. Thirty-one of the patients included (77.5%) had a high risk of choledocholithiasis, and 9 (22.5%) had an intermediate risk. In 16 (51.6%) of the 31 patients with a high risk, the diagnosis of choledocholithiasis was confirmed. In 2 (22.2%) of the 9 patients with an intermediate risk, the diagnosis of choledocholithiasis was also confirmed. The high risk score for choledocholithiasis had a positive predictive value of 52% and a sensitivity of 89%. The intermediate risk score for choledocholithiasis had a positive predictive value of 22% and a sensitivity of 11%. Discussion and Conclusions: Suspicion of choledocholithiasis in patients with acute cholecystitis was a rare event (<1%). The sensitivity of the high risk score was approximately the same as found in published series with patients with suspected choledocholithiasis overall (86%), while the positive predictive value was substantially lower (52 vs. 79.8%). Therefore, in patients with acute cholecystitis and suspected choledocholithiasis, this score should not be used to screen for common bile duct stones, and a sensitive method should be used prior to ERCP. PMID- 29457049 TI - Intestinal Obstruction of Uncommon Cause and Point-of-Care Ultrasonography - Where Do We Stand? AB - Malignant neoplasms of the small bowel, especially from the jejunum, are among the rarest types of cancer. Given its location, a delayed diagnosis is frequent and sometimes only made in an emergency context. The authors present a case of intestinal obstruction, where ultrasonography was pivotal in establishing a diagnosis. Point-of-care ultrasonography seems to be particularly sensitive in assessing emergency patients with abdominal pain, allowing effective orientation and saving human and technical resources. PMID- 29457048 TI - Farnesoid X Receptor Expression in Microscopic Colitis: A Potential Role in Disease Etiopathogenesis. AB - Introduction: Microscopic colitis (MC) is a chronic inflammatory bowel disease with unclear etiology. Bile acid (BA) malabsorption has been described in MC patients. Farnesoid X receptor (FXR) is the main BA receptor; FXR-mediated mechanisms prevent the noxious effects of BA accumulation, preserving the integrity of the intestinal epithelial barrier and preventing intestinal inflammation. Aim: Our aim was to describe the expression of FXR in patients with MC. Methods: Archival formalin-fixed paraffin-embedded samples from the terminal ileum, right and left colon were obtained from patients with MC and matched controls. Immunohistochemistry was performed and nuclear FXR expression scored in a semi-quantitative way. Results: 169 formalin-fixed paraffin-embedded samples from 35 patients with MC and 31 controls were retrieved. There was a significant reduction of FXR expression in patients with MC versus controls both in the right colon (moderate-strong FXR expression: 21.1 vs. 64.3%; p = 0.003) and left colon (moderate-strong FXR expression: 8.3 vs. 38.7%; p = 0.027). No significant differences in FXR expression were observed in the ileum of patients with MC (moderate-strong FXR expression: 76.9 vs. 90.9%; p = 0.5). We found no difference in FXR expression between the two types of MC. No association between the degree of lymphocyte infiltration or the thickness of collagen band and FXR expression was found. Conclusions: Patients with MC present a significantly lower expression of FXR in the colon. This could render colonic epithelial cells more susceptible to the deleterious effects of BA, contributing to disease pathogenesis and symptoms in MC. PMID- 29457050 TI - Pelvic Catastrophe after Elastic Band Ligation in an Irradiated Rectum. AB - Chronic radiation proctopathy is a frequent complication after both pelvic external radiation therapy and brachytherapy and most commonly presents as rectal bleeding. Deep rectal ulcers and fistulae are much rarer and more clinically challenging consequences. We present the case of a 72-year-old male with a history of prostate adenocarcinoma treated with brachytherapy, who was referred to our institution due to a deep painful rectal ulcer refractory to medical treatment. The ulcer presented shortly after a haemorrhoid elastic band ligation and progressed to rectourethral fistulisation despite both faecal and urinary diversion. Our case demonstrates the importance of favouring a conservative approach when dealing with an irradiated rectum. PMID- 29457051 TI - Signet Ring Cell Carcinoma, Ileal Crohn Disease or Both? - A Case of Diagnostic Challenge. AB - Signet ring cell carcinoma is a rare form of adenocarcinoma that predominantly affects the stomach. Signet ring cell carcinoma originated from the ileum is extremely rare and the prognosis is poor. We present a case of small bowel obstruction with features suggesting Crohn disease of the ileum. The symptoms were chronic diarrhea and abdominal pain with a family history of inflammatory bowel disease. The patient underwent surgery and histopathology revealed both aspects of signet ring cell carcinoma and Crohn disease of the ileum. An association between long-standing inflammation and the development of this subtype of tumor has been proposed but there are no established surveillance guidelines for small bowel neoplasm in inflammatory bowel disease. PMID- 29457052 TI - An Unexpected Abdominal Radiographic Finding: Chilaiditi Sign. PMID- 29457053 TI - Increased subjective experience of non-target emotions in patients with frontotemporal dementia and Alzheimer's disease. AB - Although laboratory procedures are designed to produce specific emotions, participants often experience mixed emotions (i.e., target and non-target emotions). We examined non-target emotions in patients with frontotemporal dementia (FTD), Alzheimer's disease (AD), other neurodegenerative diseases, and healthy controls. Participants watched film clips designed to produce three target emotions. Subjective experience of non-target emotions was assessed and emotional facial expressions were coded. Compared to patients with other neurodegenerative diseases and healthy controls, FTD patients reported more positive and negative non-target emotions, whereas AD patients reported more positive non-target emotions. There were no group differences in facial expressions of non-target emotions. We interpret these findings as reflecting deficits in processing interoceptive and contextual information resulting from neurodegeneration in brain regions critical for creating subjective emotional experience. PMID- 29457054 TI - Towards a whole brain model of Perceptual Learning. AB - A hallmark of modern Perceptual Learning (PL) is the extent to which learning is specific to the trained stimuli. Such specificity to orientation, spatial location and even eye of training has been used as psychophysical evidence of the neural basis of learning. This argument that specificity of PL implies regionalization of brain plasticity implicitly assumes that examination of a singular locus of PL is an appropriate approach to understand learning. However, recent research shows that learning effects once thought to be specific depend on subtleties of the training paradigm and that within even a simple training procedure there are multiple aspects of the task and stimuli that are learned simultaneously. Here, we suggest that learning on any task involves a broad network of brain regions undergoing changes in representations, read-out weights, decision rules, attention and feedback processes as well as oculomotor changes. However, importantly, the distribution of learning across the neural system depends upon the details of the training procedure and the characterstics of the individual being trained. We propose that to advance our understanding of PL, the field must move towards understanding how distributed brain processes jointly contribute to behavioral learning effects. PMID- 29457055 TI - Tuberculin skin test conversion and primary progressive tuberculosis disease in the first 5 years of life: a birth cohort study from Cape Town, South Africa. AB - Background: Tuberculosis is a leading cause of global childhood mortality. However, the epidemiology and burden of tuberculosis in infancy is not well understood. We aimed to investigate tuberculin skin test conversion and tuberculosis in the Drakenstein Child Health study, a South African birth cohort in a community in which tuberculosis incidence is hyperendemic. Methods: In this prospective birth cohort study, we enrolled pregnant women older than 18 years who were between 20 and 28 weeks' gestation and who were attending antenatal care in a peri-urban, impoverished South African setting. We followed up their children for tuberculosis from birth until April 1, 2017, or age 5 years. All children received BCG vaccination at birth. Tuberculin skin tests were administered to children at 6, 12, 24, 36, 48, and 60 months of age, and at the time of a lower respiratory tract infection. An induration reaction of 10 mm or more was considered to be a tuberculin skin test conversion. To prevent boosting, we censored children with a reactive, negative tuberculin skin test. Findings: Among 915 mother-child pairs (201 [22%] HIV-positive mothers and two [<1%] HIV positive children), 147 (16%) children had tuberculin skin test conversion, with increasing cumulative hazard with age (0.08 at 6 months, 0.17 at 12 months, 0.22 at 24 months, and 0.37 at age 36 months). For every 100 child-years, the incidence was 11.8 (95% CI 10.0-13.8) for tuberculin skin test conversion, 2.9 (2.4-3.7) for all diagnosed tuberculosis, and 0.7 (0.4-1.0) for microbiologically confirmed tuberculosis. Isoniazid preventive therapy was effective in averting disease progression (adjusted hazard ratio 0.22, 95% CI 0.08-0.63; p<0.0001). Children with a lower respiratory tract infection were significantly more likely to also have tuberculosis than were those without one (2.27, 1.42-3.62; p<0.0001). Interpretation: Greater focus should be placed on the first years of life as a period of high burden of transmission and clinical expression of tuberculosis infection and disease. Multifaceted interventions, such as isoniazid preventive therapy and tuberculosis screening of infants with LRTIs, beginning early in life, are needed in high-burden settings.

PMID- 29457056 TI - When can we give general anesthesia to an infant with anticipated difficult airway management caused by facial vascular malformation? AB - A 13-month-old infant weighing 8.3 kg with a height of 72.3 cm visited our hospital for surgical resection of facial vascular malformation detected at birth. Because we anticipated the patient would have difficult airway management and massive perioperative bleeding, we postponed surgery to discuss the appropriate timing and general anesthesia approach with anesthesiologists at other institutions, while explaining the risk of general anesthesia and bleeding to the parents. When the patient was 21 months old and 10 kg, he started bleeding while undressing, when his lips touched his clothes. Because the cricothyroid membrane puncture kit (QuickTrach ChildTM (VBM Medizintechnik GmbH, Sulz am Neckar, Germany)) can be used on infants weighing over 10 kg, we decided to give him general anesthesia. The infant was successfully intubated by AirwayscopeTM and the lesion was surgically removed in accordance with the preoperative plan. The procedure took 65 min and created 8 g of bleeding. The infant had no postoperative bleeding or respiratory complications. There is no data on the timing of safe anesthesia management in infants with difficult airway management. Thus, taking the time to discuss the case with surgeons, other anesthesiologists, and the parents can be helpful. PMID- 29457057 TI - Low preoperative regional cerebral oxygen saturation in hemodialysis patients. AB - Background: Regional cerebral oxygen saturation (rSO2) monitoring by near infrared spectroscopy provides valuable information regarding cerebral oxygen delivery, and it has been increasingly used in cardiovascular surgery. Although it has been shown that dialysis-dependent patients [hemodialysis (HD) patients] suffer from low cerebral perfusion, limited information is available on cerebral tissue oxygenation levels in HD patients. Findings: In this retrospective study, the preoperative rSO2 values in 9 HD patients undergoing coronary artery bypass graft surgery were compared with those in 40 non-HD patients. HD patients had lower preoperative rSO2 values than non-HD patients (median: 46 vs. 68%, respectively, P < 0.001). Despite adjusting for age, hemoglobin concentration, and left ventricular ejection fraction using multivariable linear regression, HD showed a strong association with low rSO2 (estimated coefficient: -20.4, P < 0.001). Conclusions: HD showed a strong association with low preoperative rSO2 values in patients undergoing coronary artery bypass graft surgery, even after adjusting for known factors that affect rSO2 values, including age, hemoglobin concentration, and cardiac systolic function. Further research is required to elucidate the mechanisms decreasing rSO2 values in HD patients. PMID- 29457058 TI - Coronary ostial stenosis detected by transesophageal echocardiography after aortic valve replacement: a case report. AB - Background: Coronary ostial stenosis is a life-threatening complication of aortic valve replacement (AVR). Clinical symptoms usually appear within the first 6 months after AVR (Funada and Mizuno et al., Circ J 70:1312-7, 2006), and perioperative onset is very rare. Case presentation: An 80-year-old woman with severe aortic stenosis was scheduled to undergo AVR. AVR using cardiopulmonary bypass (CPB) was successfully carried out. However, 5 min following AVR, signs of left heart failure appeared, and transesophageal echocardiography (TEE) revealed severe hypokinetic left ventricular wall motion. Left coronary ostial stenosis was diagnosed by TEE, and CPB was immediately resumed and coronary artery bypass grafting (CABG) to the left anterior descending branch was performed. Conclusions: When circulatory failure presents in the acute phase following AVR, onset of coronary ostial stenosis should be considered. PMID- 29457059 TI - Unexpected bioprosthetic mitral valve thrombus during left ventricular assist device implantation. AB - Acute bioprosthetic valve thrombosis can occur after surgery and sometimes cause hemodynamic instability and cardiogenic shock. Risk factors for bioprosthetic valve thrombosis are hypercoagulability, atrial fibrillation, atrial dilatation, low cardiac function, and lack of anticoagulation therapy. The authors present a case of severe mitral stenosis due to bioprosthetic valve thrombus. The patient was diagnosed with dilated-phase hypertrophic cardiomyopathy and underwent mitral valve replacement. He required venoarterial extracorporeal membrane oxygenation (VA-ECMO) due to extremely low cardiac output and was scheduled for left ventricular assist device (LVAD) implantation. Transesophageal echocardiographic examination before LVAD implantation revealed severe mitral stenosis due to bioprosthetic mitral valve thrombus, which was not detected by transthoracic echocardiography in the intensive care unit and contributed to the low cardiac function. The thrombus was removed through an unscheduled left atriotomy before LVAD implantation. The possibility of bioprosthetic valve thrombosis must be considered when the patient is dependent on VA-ECMO support. Early transesophageal echocardiographic examination of the bioprosthetic valve may be helpful and contribute to surgical decision-making. PMID- 29457060 TI - Lower airway obstruction due to a massive clot resulting from late bleeding following mini-tracheostomy tube insertion and subsequent clot removal and re intubation. AB - Background: Easier to perform than the conventional procedure, mini-tracheostomy (MT) is widely used in the operating room or intensive care unit to remove sputum or other obstructions of the upper airway. This option, however, does carry the risk of various complications, including malposition, disposition, bleeding, and subcutaneous emphysema. Here, we report a case of endotracheal tube obstruction due to a massive clot resulting from late bleeding around the insertion site of an MT tube. This necessitated removal of the endotracheal tube together with the clot followed tube re-introduction. Case presentation: The patient was an 85-year old man in whom an MT tube had been inserted 6 days earlier following aortic replacement surgery. On re-admittance to our intensive care unit, large amounts of hemosputum and clotting were observed around the insertion site of the tube. The MT tube was subsequently removed and tracheal intubation performed. Ventilation via the endotracheal tube proved impossible, however, and cardiac arrest ensued. Fiberoptic bronchoscopy revealed that the endotracheal tube was completely obstructed by a massive clot. Therefore, we immediately pushed the clot toward the right main bronchus to secure ventilation via the left lung. After many attempts to remove the massive clot, including suction and grasping with basket forceps, it was successfully dislodged by replacing the endotracheal tube with a new one while maintaining oxygenation by one-lung ventilation. Any small fragments of the clot that still remained were then removed by suction under fiberoptic bronchoscopy. Conclusions: Here, we report a case of endotracheal tube obstruction due to a clot derived from very late (6 days) bleeding after insertion of an MT tube. The patient was successfully rescued by replacing the clot-bearing endotracheal tube with a new one. This experience suggests that the intensive care physician should be aware of the potential risk of clot retention in endotracheal tubes after the elapse of several days. PMID- 29457061 TI - Postoperative management with dexmedetomidine in a pregnant patient who underwent AVM nidus removal: a case report. AB - Background: Following cerebral arteriovenous malformation (AVM) surgery, severe brain edema and hemorrhage may be caused by postoperative normal perfusion pressure breakthrough (NPPB). Sedation is necessary for this population. It is a challenge for the anesthesiologist to maintain hemodynamic stability without interfering with the neurological assessment. In Japan, propofol is contraindicated for pregnant patients. Dexmedetomidine is a versatile drug in anesthesia practice and may be useful for this situation. There is no report using dexmedetomidine for the purpose of NPPB control in pregnant patients. We describe the postoperative management with dexmedetomidine for a pregnant patient who underwent cerebral AVM nidus removal. Case presentation: A 32-year-old patient presented with headache at the 16th week of gestation. Neuroimaging revealed an intraventricular hemorrhage and an AVM at the right anterior horn of the lateral ventricle which caused bleeding. A multidisciplinary team discussion was done, and then a craniotomy for AVM nidus removal was performed under general anesthesia. Preanesthetic aspiration prophylaxis and rapid sequence induction were added to our conventional anesthetic management. Hypotension occurred after anesthetic induction but the patient recovered by volume resuscitation and vasopressors. Anesthesia was maintained with 50% O2 in air and sevoflurane. The AVM was completely removed, and no perioperative complications occurred. Postoperative sedation with dexmedetomidine was used to prevent breakthrough hyperperfusion and cerebral edema. Conclusions: Dexmedetomidine infusion was used for postoperative sedation without causing any side effects, and it can be an alternative for sedation, especially when propofol is contraindicated. PMID- 29457062 TI - A case of left frontal high-grade glioma diagnosed during pregnancy. AB - Background: As pregnancy accelerates glioma growth, therapeutic abortion has been recommended prior to tumor resection. Additionally, it has also been suggested that the extent of glioma resection is closely correlated with patient survival. Case presentation: A 162-cm, 61.4-kg, 30-year-old, right-handed primigravida was referred to our institution at 21 weeks gestation to obtain a second opinion. At 18 weeks gestation, the patient developed new-onset generalized convulsive seizures (GCSs), which were poorly controlled by anticonvulsant polytherapy, early in the second trimester. A 6-cm lesion located in her left frontal supplementary motor area (SMA) was suspected as a grade III glioma, classified according to the World Health Organization (WHO) guidelines. Due to the limited evidence on the use of adjuvant therapy during pregnancy, tumors causing neurological symptoms and seizures must be treated, in order to stabilize the maternal condition and enable a safe birth. In the case of pregnant patients, awake craniotomy using intraoperative magnetic resonance imaging (iMRI) is considered advantageous, achieving gross total resection with a reduction of direct cortical stimulation, which may induce seizure, and so reducing fetal exposure to anesthetics. The "Asleep-Awake-Asleep" technique was performed at 27 weeks and 2 days gestation. As use of propofol in pregnant patients is prohibited, general anesthesia was maintained through administration of sevoflurane and remifentanil until the first scan of iMRI, and was subsequently re-induced with dexmedetomidine when tumor removal had been accomplished. A supraglottic airway (SGA) was used until the patient's cranium was opened. There were no complications during either the procedure or the post-operative period. At 35 weeks gestation, the patient delivered a healthy baby of 2317 g. Pathological examination of the patient, revealed an anaplastic astrocytoma, thus radiotherapy and chemotherapy began 2 months post-delivery. There is no evidence of tumor recurrence in the patient and the child did not show any medical or developmental concerns at the point of the 17-month follow-up. Conclusions: Since evidence on the use of adjuvant therapy during pregnancy is limited, extensive resection with functional monitoring is recommended if a brain tumor is presumed to be malignant. Awake craniotomy is considered advantageous to pregnant patients because subjective movement preserves the patient's motor function and reduces fetal exposure to anesthetics. Therefore, providing multidisciplinary discussion takes place within the decision-making process, as well as careful perioperative preparation, awake craniotomy should be considered, even in the case of pregnant patients. PMID- 29457063 TI - Monitoring of central venous pressure and stroke volume variation in a case with a ruptured brain arteriovenous malformation and Fontan circulation. AB - Background: Patients with complex congenital heart disease increasingly undergo noncardiac surgeries because of advancements in surgical techniques and medical management. In Fontan circulation, maintaining an adequate transpulmonary gradient is essential for preserving both pulmonary blood flow and cardiac output. However, intraoperative circulatory monitoring of Fontan patients has not been established. Case presentation: A 17-year-old girl required an emergency craniotomy for ruptured arteriovenous malformation. She had a surgical history of bidirectional Glenn operation and Fontan palliation for her congenital hypoplastic left heart syndrome and double outlet right ventricle. We performed general anesthesia with continuous monitoring of central venous pressure (CVP) and stroke volume variation (SVV). Transesophageal echocardiography was not conducted because of difficulty in manipulating the probe due to the patient's position and surgical setting. After incision of the dura, approximately 1700 ml of rapid blood loss from the arteriovenous malformation was observed in 30 min. In this period, CVP decreased from 15 to 5 mmHg or less. In contrast, there was only a slight rise in SVV from 5 to 8%. We rapidly administered fluid and then transfused blood, and CVP gradually recovered to 10-15 mmHg. During the surgery, circulatory collapse was not observed. The patient was transferred to the intensive care unit under sedation and controlled ventilation. Conclusions: CVP decreased sharply, whereas SVV rose only slightly during acute bleeding in the present case. CVP monitoring may have been useful for the management of an acute bleeding case with a Fontan circulation but SVV may not have been reliable. As more patients with a Fontan circulation undergo noncardiac surgeries, appropriate circulatory monitoring in these patients should be further investigated. PMID- 29457064 TI - A case of sudden onset of thyroid storm just before cesarean section manifesting congestive heart failure and pulmonary edema. AB - Background: Since acute respiratory failure (ARF) is a life-threatening complication, particularly in the gestational period, differential diagnosis and rapid treatment are required. Among the various causes of sudden onset of ARF, thyroid storm is a rare cause in a parturient complicated with well-controlled hyperthyroidism. In this case report, we describe a parturient with hyperthyroidism in whom a thyroid storm manifesting congestive heart failure and pulmonary edema developed just before an emergency ceasarean section, even though hyperthyroidism was well-controlled with antithyroid drugs. Case presentation: A 36-year-old pregnant woman was diagnosed as having clinical chorioamnionitis, and an emergency cesarean section was performed at 25 weeks of pregnancy. She had a complication of hyperthyroidism accompanied by mild mitral regurgitation, and she had been treated with methimazole. She was treated with ritodrine and MgSO4 for the threat of premature delivery. At the preoperative consultation, her percutaneous oxygen saturation (SpO2) was 98% on room air. When she was admitted to the operating room, her heart rate and blood pressure were 130 beats/min and 196/78 mmHg, respectively. SpO2 was 88% on room air without any symptoms; however, just after starting oxygen administration via a facemask, she complained of severe respiratory distress and became agitated. Partial pressure of arterial oxygen was 108 mmHg with an inspiratory oxygen fraction of 1.0. Chest radiography revealed pulmonary congestion, and transesophageal echocardiography revealed normal right ventricular function without an embolus and severe mitral regurgitation with preserved left ventricular function. Contrast-enhanced computed tomography after the operation revealed no pulmonary embolus but revealed a pulmonary effusion, and free triiodothyronine level was increased at the onset of dyspnea. Therefore, we diagnosed the causes of sudden onset of dyspnea as pulmonary edema and congestive heart failure induced by a thyroid storm. Conclusion: Sudden onset of a thyroid storm just before a cesarean section occurred in a patient with several risk factors of thyroid storm and pulmonary edema, including pregnancy, treatment with tocolytic agents, and infection. The involvement of these multiple factors was considered to be the cause of the sudden onset of the thyroid storm and the cause of rapidly progressive pulmonary edema. PMID- 29457065 TI - A devised strategy for tracheal extubation for predicted difficult airway in a child with unilateral vocal cord paralysis: a case report. AB - Background: Extubation is a more challenging medical practice than intubation, and countermeasures against it are similar to those described in the Difficult Intubation Guidelines, but problems cannot be overcome by completely the same methods. We predicted difficult extubation in a pediatric patient with left recurrent laryngeal nerve paralysis and devised an extubation method. Case presentation: The patient was a 2-year-and-8-month-old boy scheduled for cleft palate repair. Concomitant cardiac anomaly and first and second branchial arch syndrome-associated facial malformations, such as mandibular micrognathia and auricular malformation, were observed. He had a past medical history of difficult intubation and respiratory arrest on a catheter test under intravenous sedation at 4 months old. Left recurrent laryngeal nerve paralysis was discovered on preoperative examination of the cleft palate, based on which difficulty in postoperative extubation was predicted. A catheter for tracheal tube exchange proposed by the extubation guidelines of the Difficult Airway Society (DAS) was placed, endoscopic examination was performed while inducing spontaneous breathing and swallowing reflex by an otolaryngologist, and the tube was removed while movement of the tissue around the glottis was visually evaluated. The patient was managed in an ICU after extubation, and both the systemic and respiratory conditions were favorable. Conclusions: Extubation and airway management could be safely performed by devising extubation while conforming to the DAS guidelines. PMID- 29457066 TI - Dexmedetomidine-treated hyperventilation syndrome triggered by the distress related with a urinary catheter after general anesthesia: a case report. AB - Background: Hyperventilation syndrome (HVS) sometimes occurs in patients under stressful conditions and may provoke severe complications such as myocardial infarction and death. The authors report a case of HVS following general anesthesia, where a continuous intravenous infusion of dexmedetomidine was effective for HVS. Case presentation: A 23-year-old male patient with recurrent tongue cancer was scheduled to undergo partial glossectomy and neck dissection. Emergence from general anesthesia was prompt. Twenty-two minutes after extubation, the patient complained of unbearable distress caused by the urinary catheter. He began to cry, with an increased respiratory rate of over 40 breaths per minute. Intravenous infusion of flurbiprofen, droperidol, and morphine was not effective. Electrocardiography and laryngofiberscopy indicated the absence of acute coronary syndrome and airway obstruction, respectively. An arterial blood gas determination showed pH 7.63, PaCO2 18.2 mmHg, PaO2 143 mmHg on O2 mask 4 L/min, Ca2+ 4.29 mmol/L, and lactate 3.4 mmol/L. The patient was diagnosed with HVS. Dexmedetomidine infusion 2.0 MUg/kg/h for 10 min followed by 0.7 MUg/kg/h reduced respiratory rate, suppressed arousal, and disappeared the complaint of bladder distension. One hour after extubation, an arterial blood gas determination showed pH 7.33, PaCO2 51.3 mmHg, PaO2 196 mmHg on O2 mask 4 L/min, Ca2+ 4.70 mmol/L, and lactate 1.5 mmol/L. After admission to the intensive care unit, dexmedetomidine infusion was maintained at the rate of 0.2 to 0.7 MUg/kg/h until the following morning, and he did not complain of distress caused by the urinary catheter. Conclusions: HVS can occur after emergence from general anesthesia, and dexmedetomidine infusion was effective for HVS. PMID- 29457067 TI - An educational program for decreasing catheter-related bloodstream infections in intensive care units: a pre- and post-intervention observational study. AB - Background: Central venous catheters (CVCs) are commonly used in the management of critically ill patients. This study aimed to determine whether an educational program could reduce the rate of catheter-related bloodstream infections (CRBSIs) in intensive care units (ICUs). Findings: All patients admitted to a medical ICU at a college affiliated with the Japan Society of Intensive Care Medicine between January 2008 and December 2014 were surveyed prospectively for the development of CRBSIs. A mandatory educational program (the intervention) targeting an infection control committee consisting of physicians was developed by a multidisciplinary task force to highlight correct practices for preventing CRBSIs. The program included a 30-min video-based introduction, 120-min lectures with a number of hands-on training sessions, a post-test, posters, safety check sheets, and feedback from the infection control committee. Lectures based on the education program were held every 3 months, and participants were free to choose when they attended the lectures. Each participant was required to view the 30-min introduction before attending the 120-min lectures and complete the post-test after each lecture. Safety check sheets were made to ascertain adherence to contents of the educational program. Posters describing the educational program were posted throughout the ICU. A pre- and post-intervention observational study design was employed, with the main outcome measure being yearly CRBSIs. We also calculated cost savings that resulted from improved CRBSI rates.During the 12 month pre-intervention period, four episodes of CRBSIs occurred in 1171 patient ICU-days (i.e., 3.4 per 1000 patient ICU-days). In the first year after the intervention, the rate of CRBSIs decreased to 0 in 1157 patient ICU-days (P <= 0.05). The estimated cost savings secondary to this decreased rate for the 1 year following introduction of the program was between 1850,000 and 27,000,000 yen ($14,800-$216,000). Conclusions: A program aimed at educating healthcare providers on the prevention of CRBSIs led to a dramatic decrease in the rate of primary bloodstream infections. This suggests that educational programs may substantially decrease medical care costs and patient morbidity attributed to central venous catheterization when implemented as part of mandatory training. PMID- 29457068 TI - Abdominal compartment syndrome during hip arthroscopy for an acetabular fracture: a case report. AB - Background: We encountered a case of abdominal compartment syndrome during hip arthroscopic surgery, caused by the irrigation fluid flowing into the peritoneal cavity. Case presentation: A 47-year-old male patient with the acetabulum fracture underwent open reduction and internal fixation with hip arthroscopy. Hypothermia, increased airway pressure (under volume-controlled ventilation) and oliguria were observed during the operation, and arterial blood gas analysis showed decreased oxygenation and metabolic acidosis. Abdominal distention was observed, and a postoperative CT revealed accumulation of a large volume of irrigation fluid in the peritoneal cavity and retroperitoneum. The patient was diagnosed as having abdominal compartment syndrome and treated by percutaneous peritoneal drainage. His subsequent course was uneventful, and he was discharged 8 weeks after the operation. Intraperitoneal extravasation of irrigation fluid may occur during hip arthroscopic surgery, and is more likely to occur in the presence of an injury. Conclusion: Anesthesiologists should be aware of the possible occurrence of the abdominal compartment syndrome during hip arthroscopic surgery and ensure that it is detected early. PMID- 29457069 TI - Bacillus cereus pneumonia in an immunocompetent patient: a case report. AB - Background: Bacillus cereus (B. cereus) rarely causes lower respiratory tract infections, although most reported cases of B. cereus pneumonia are fatal despite intensive antibiotic therapy. We present a case of B. cereus pneumonia in an immunocompetent patient. Case presentation: An 81-year-old woman was transferred from a district general hospital to our hospital for treatment of congestive heart failure. The patient presented with a nonproductive cough, dyspnea, edema in both lower extremities, orthopnea, fever, and occult blood in the stool. A chest radiograph indicated bilateral pleural effusion and pulmonary congestion. After diuretic therapy and chest drainage, bilateral pleural effusion and pulmonary congestion improved. On day 2, she experienced severe respiratory distress. B. cereus was isolated from two blood sample cultures. On day 4, her condition had progressed to severe respiratory distress (PaO2/FiO2 ratio = 108). A chest radiograph and computed tomography indicated extensive bilateral infiltrates. She was transferred to the intensive care unit and was intubated. B. cereus was also isolated from five blood sample cultures at that time. After isolating B. cereus, we switched antibiotics to a combination of imipenem and levofloxacin, which were effective. She had no history of immunodeficiency, surgery, ill close contacts, risk factors for HIV or tuberculosis, recent central venous catheter insertion, or anthrax vaccination. She improved and was discharged from the intensive care unit after several days. Conclusion: This is a rare case of B. cereus pneumonia in an immunocompetent patient, who subsequently recovered. Bacillus should be considered as a potential pathogen when immunocompetent patients develop severe pneumonia. PMID- 29457070 TI - Sudden onset of artery dissection in a 32-year-old woman with vascular Ehlers Danlos syndrome due to psychological stress of her mother's death: a case series. AB - Background: Patients with vascular Ehlers-Danlos syndrome (EDS) are susceptible to significant vascular complications, such as aortic and visceral arterial ruptures, aneurysms, and dissection. We describe a case of repeated bleeding in a 57-year-old woman and a case of sudden onset of artery dissection in her daughter, both of whom were previously diagnosed with vascular EDS and managed at our institution. Case presentation: A 57-year-old woman was admitted to our emergency department due to sudden onset of left low back pain. Her past history included vascular EDS. An urgent abdominal computed tomography (CT) scan revealed a left-sided retroperitoneal hematoma and left external iliac artery dissection. Stent graft repair was performed. Five hours postoperatively, cardiac arrest occurred and resuscitation attempts failed. The 32-year-old daughter with genetically diagnosed vascular EDS was notified of the death of her mother during the customary end-of-life conference. Six hours after her mother's death, she was admitted to our emergency department due to sudden onset of left low back pain. On examination, she was not in hypovolemic shock, and weak pulses were palpable in the bilateral dorsalis pedis. An urgent abdominal CT scan revealed a right sided retroperitoneal hematoma around the right external iliac artery and left external iliac artery dissection. She was admitted to the intensive care unit and underwent conservative therapy consisting of bed rest and antihypertensive therapy with nicardipine. She developed no further vascular complications requiring surgical intervention and was discharged on the 21st hospital day. Conclusions: Vascular rupture can be fatal in patients with vascular EDS. This report underscores the importance of strategic management of vascular complications to prevent rupture, and the importance of psychological care for the bereaved family given the hereditary nature of vascular EDS. PMID- 29457071 TI - General anesthesia in a patient with asymptomatic second-degree two-to-one atrioventricular block. AB - Background: The major perioperative concern in patients with second-degree atrioventricular (AV) block is the progression to complete AV block. Therefore, the prophylactic implantation of a temporary pacemaker prior to surgery is recommended, especially in symptomatic patients. However, as no quantitative preoperative risk assessment from progression to complete AV block is available, there is currently no established indication for preoperative prophylactic pacemaker implantation. Here, we present a case of progression from asymptomatic second-degree two-to-one (2:1) AV block to complete AV block following the induction of general anesthesia. Case presentation: A 69-year-old female with degenerative spinal stenosis was scheduled for transforaminal lumbar interbody fusion surgery under general anesthesia. She had no cardiac symptoms, but routine preoperative resting 12-lead electrocardiogram revealed second-degree 2:1 AV block. After discussion with the surgeon and referring cardiologist, we scheduled the surgery without implantation of a temporary pacemaker before surgery for the following reasons: (1) asymptomatic, (2) no evidence of underlying cardiac disease, and (3) a narrow QRS complex. On the day of surgery, general anesthesia was induced with 150 mg of intravenous thiamylal and 25 MUg of fentanyl, followed by intravenous administration of 50 mg of rocuronium to facilitate endotracheal intubation. Sevoflurane (1.0-2.0%) was used to maintain anesthesia. A few minutes after induction, the 2:1 AV block progressively converted to complete AV block, and the surgery was postponed. During emergence from anesthesia, the third-degree AV block recovered to 2:1 AV block, similar with the preoperative pattern. The patient was monitored in the intensive care unit for 2 days and then transferred to the normal orthopedic ward uneventfully. One month later, the surgery was rescheduled with preoperative implantation of a temporary pacemaker. A slow mask induction using sevoflurane with oxygen was started. Upon loss of consciousness during the inhalation of initial sevoflurane, complete AV block developed and temporary pacing was immediately initiated. Subsequent anesthesia and surgery were uneventful. The patient made an uncomplicated recovery from surgery with stable hemodynamics. The temporary pacemaker was not required after surgery, and the pacemaker catheter was removed 1 day after surgery. Conclusions: The present case indicates that a prophylactic pacemaker should be implanted preoperatively in patients who have 2:1 AV block even without symptoms. PMID- 29457072 TI - Anesthetic management of cesarean section in a patient with a large anterior mediastinal mass: a case report. AB - Background: Symptomatic anterior mediastinal mass in pregnancy is rare, and cesarean section for such patients poses a risk of cardiopulmonary collapse. Case presentation: A 30-year-old woman at 40 weeks' gestation complained of breathlessness and cough, and she was not able to lie supine because of respiratory distress. Computed tomography scan revealed a large anterior-superior mediastinal mass severely compressing the trachea, bilateral main bronchus, and superior vena cava. Because clinical symptoms and computed tomographic findings suggested imminent respiratory catastrophe, urgent cesarean section was planned. The patient was able to lie in the semi-recumbent position with minimal symptoms; therefore, we considered it safe to perform cesarean section with combined spinal epidural anesthesia. In the event of cardiopulmonary collapse, emergent intubation and extracorporeal membrane oxygenation were also planned. The operation was performed successfully with combined spinal epidural anesthesia. The infant was healthy, and the postoperative hospital course was uneventful. Conclusions: Combined spinal epidural anesthesia is preferable in the anesthetic management of cesarean section with symptomatic anterior mediastinal mass. A well designed preoperative strategy can lead to favorable outcomes even in this complicated situation. PMID- 29457073 TI - Sevoflurane prolonged the QTc interval and increased transmural dispersion of repolarization in a patient with long QT syndrome 3: a case report. AB - We report that sevoflurane not only caused marked QTc interval prolongation but also increased transmural dispersion of repolarization in a patient with long QT syndrome 3 (LQT3). A 16-year-old male with LQT3 underwent a shoulder operation. He experienced no episode of syncope or cardiac arrest, but his preoperative electrocardiography (ECG) showed marked QTc interval prolongation (631 ms) and Tp e interval prolongation (126 ms). Anesthesia was induced with propofol and maintained with 2% sevoflurane and remifentanil. Although no lethal arrhythmias occurred in the perioperative period, not only the QTc interval but also Tp-e interval was further prolonged by sevoflurane. While sevoflurane has been recognized as a safe anesthetic in terms of QT interval prolongation, even in patients with long QT syndromes, we believe that sevoflurane might be avoided for poorly controlled LQT3 patients. PMID- 29457074 TI - Effect of different surgical procedures on the accuracy of prediction of the plasma concentration of fentanyl: comparison between mastectomy and laparoscopic prostatectomy. AB - Background: The accuracy of simulation-predicted fentanyl concentration in different types of surgical procedure is not fully understood. We wished to estimate the effect of different types of surgical procedure on the accuracy of such simulations. Findings: Fifty patients who had undergone elective mastectomy or laparoscopic prostatectomy (American Society of Anesthesiologists physical status = I-II) were enrolled. Anesthesia was maintained throughout surgery with sevoflurane and a bolus infusion of fentanyl. A maintenance infusion was administered with 8 mL/kg/h Ringer's acetate solution from the start of anesthesia to completion of blood sampling. An infusion to compensate for blood loss was administered (one to two volumes of hydroxyethyl starch). A blood sample was drawn every 30 min during anesthesia.We measured the plasma concentration of fentanyl in 358 samples from 50 patients. The plasma concentration of fentanyl was correlated significantly with the simulated predicted fentanyl concentration (r = 0.734, P < 0.01) but 36.0% of all samples had a difference greater than +/ 0.5 ng/mL. Approximately 0.3 ng/mL of a fixed bias was shown throughout mastectomy. During laparoscopic prostatectomy, the fixed bias gradually became negative from ~0.3 to -0.3 ng/mL as the sampling stage proceeded. Conclusions: The predicted concentration of fentanyl was significantly correlated with the plasma concentration of fentanyl (r = 0.734). However, there were different patterns of a fixed bias between mastectomy and laparoscopic prostatectomy groups. We should pay attention to this tendency among different surgical procedures. Trial registration: UMIN000005110. PMID- 29457075 TI - A case of unexpected impaired oxygenation due to intraoperative pneumothorax: an adverse event associated with respiratory management with spontaneous respiration in a patient with esophagobronchial fistulae. AB - Background: Respiratory management in patients with esophagobronchial fistulae is challenging since positive pressure ventilation (PPV) may not be feasible due to air leaks and possible risks for regurgitation and aspiration of gastric contents. We and others have previously reported that spontaneous respiration may be one of the good options of respiratory management during general anesthesia in those patients. However, adverse events associated with this respiratory strategy have not been reported previously. We experienced a 77-year-old male patient who suffered unexpected impairment of oxygenation due to intraoperative pneumothorax, which was assumed to have been exacerbated by spontaneous respiration during esophageal bypass surgery. Case presentation: The patient was planned to undergo esophageal bypass surgery for esophagobronchial fistulae associated with malignant esophageal cancer. Both of two esophagobronchial fistulae were located in the proximal part of the left main bronchus. For the risks of air leaks and aspiration associated with PPV and further damage to the tissue around the fistulae, we decided to maintain spontaneous respiration under general anesthesia and obtain abdominal muscle relaxation with epidural anesthesia. After catheterization of epidural anesthesia, the patient was sedated with 35 mg of intravenous pethidine and was nasotracheally intubated under bronchoscopic guidance. We confirmed that the tip of the tracheal tube was located above the carina. Then anesthesia was induced and maintained with sevoflurane so that his spontaneous respiration could be maintained thereafter. His spontaneous respiration was assisted with 3 cmH2O of pressure support. Approximately 60 min into the surgery, percutaneous arterial oxygen saturation (SpO2) suddenly dropped from 99 to 89% with an inspiratory fraction of oxygen of 0.4. We assumed that lung atelectasis associated with airway secretion or pulmonary soiling was the most likely reason for impaired oxygenation; however, arterial oxygenation only partially regained even after they were suctioned. After the completion of the surgery, chest X-ray revealed right pneumothorax. After a chest drainage tube was inserted, right pneumothorax was ameliorated and SpO2 returned to the baseline level. Conclusions: Although spontaneous respiration may be useful in a patient with esophagobronchial fistulae, oxygenation can be impaired more seriously than PPV in case intraoperative pneumothorax occurs. PMID- 29457076 TI - Schwartz-Jampel syndrome is not related to malignant hyperthermia. AB - Schwartz-Jampel syndrome (SJS) is a rare syndrome that is clinically characterized by myotonia and skeletal abnormalities. Most reports regarding SJS have stated that patients with SJS are susceptible to malignant hyperthermia (MH). The statement is incorrect. There is no report showing that SJS is related to MH. Scientific evidence also shows that patients with myotonias are not susceptible to MH except for that with hypokalemic periodic paralysis. Medical practitioners must recognize that SJS is not related to MH. PMID- 29457077 TI - Ultrasound-guided para-umbilical block: a pediatric case. AB - Background: Rectus sheath block is a common peripheral nerve block for patients undergoing umbilical hernia repair surgery. However, rectus sheath block alone can affect only anterior branches of intercostal nerves and, therefore, is incomplete for postoperative analgesia for the anterior abdomen, which is innervated by both anterior and lateral branches. We describe a successful perioperative analgesia with ultrasound-guided para-umbilical block after pediatric umbilical hernia surgery. Case presentation: A 4-year-old child underwent hernia repair surgery. Following induction of general anesthesia, the anatomy of the umbilical region was observed under ultrasound with a 5-10-MHz linear probe. An ultrasound-guided injection between the rectus abdominis muscle and the posterior lobe of the rectus sheath and an injection into the subcutaneous space around the umbilicus were performed. The peripheral nerve block was effective during surgery, and the patient required no additional rescue analgesia during the perioperative period. There were no complications. Conclusion: We performed ultrasound-guided para-umbilical block with four injections. This peripheral nerve block could be an efficient technique for complete perioperative analgesia. PMID- 29457078 TI - Endovascular repair with extracorporeal membrane oxygenation as a rescue strategy for aortobronchial fistula: a case report. AB - Aortobronchial fistula (ABF) is a rare and potentially lethal complication of thoracic aortic replacement surgery. Currently, thoracic endovascular aortic repair (TEVAR) has emerged as a less invasive alternative to open surgery for ABF to facilitate prompt hemostasis. However, there are no published reports of TEVAR for ABF, particularly for presentation with life-threatening respiratory failure from massive hemoptysis. A 48-year-old male patient, who had recently undergone aortic root and arch replacement due to aortic dissection, was transferred to the emergency department with massive hemoptysis and severe dyspnea. A single-lumen endotracheal tube was immediately placed in the right main bronchus to protect the nonbleeding lung from spillage of blood. Chest computed tomography (CT) showed leakage of contrast material from the distal anastomosis of the aortic graft and consolidated lung tissue adjacent to the leakage. He was diagnosed with an ABF following aortic arch replacement, and an emergency TEVAR was performed. After adequate hemostasis, severe hypercapnia remained uncorrected despite the maximum ventilatory support. Thus, venovenous extracorporeal membrane oxygenation (VV ECMO) was immediately initiated, and severe respiratory acidosis improved dramatically. Furthermore, VV ECMO facilitated prompt bronchoscopic washout of the remaining blood clot without any danger of respiratory collapse and was weaned off successfully after 5 days as ventilation improved. This case demonstrates that emergency TEVAR in combination with VV ECMO can be a rescue strategy for massive hemoptysis from an ABF. PMID- 29457079 TI - A case of a warfarinized renal cancer patient monitored for prothrombin time international normalized ratio during methadone introduction. AB - Background: Warfarin, a widely used anticoagulant, interacts with various agents used in palliative care, such as oxycodone, morphine, acetaminophen, and non steroidal anti-inflammatory drugs (NSAIDs); however, there are no reports of its interaction with methadone. We report a case of a patient receiving warfarin when methadone was introduced for pain control with monitoring of the prothrombin time international normalized ratio (PT-INR) and deduced the pharmacological background. Case presentation: A 60-year-old male was emergently admitted to our university hospital for the sudden onset of severe back pain. Abdominal CT imaging revealed that the vertebral body of the ninth thoracic vertebra was occupied by bone metastasis and crushed, which caused his back pain. He received warfarin 3.5 mg/day for atrial fibrillation and tapentadol 100 mg p.o. daily for pain relief. The prothrombin time-international normalized ratio (PT-INR) was maintained at >2.2. The patient's history included diabetes mellitus and hypertension, but his laboratory test was unremarkable with the exception that his eGFR was 34 ml/min.Initially, a fentanyl dermal patch was used instead of tapentadol to avoid interactions with warfarin. We started concomitant administration of oxycodone and 2.4 g/day of acetaminophen while monitoring the PT-INR because acetaminophen increased the PT-INR to 2.93. A continuous intravenous infusion of oxycodone was introduced, in increments of the dose, resulting in an increase of the PT-INR to 3.41, which is required to reduce the dose of warfarin to 1.5 mg. Because of the lack of effective pain relief, methadone was introduced and the dose was gradually increased. The PT-INR was not changed and the dose of warfarin was not changed. An infusion of oxycodone and oral methadone was used to allow the patient to walk in his room, and he was later transferred to the palliative hospital. Conclusions: In an oral warfarinized patient, methadone seemed to undergo different metabolism than oxycodone. When warfarin and methadone are used together, we have to consider their interaction by comparing the competitive inhibition of CYP2C9 to the induction of CYP3A4 by methadone, because CYP3A4 metabolize various drugs including oxycodone. PMID- 29457080 TI - Desflurane anesthesia worsens emergence agitation in adult patients undergoing thyroid surgery compared to sevoflurane anesthesia. AB - Background: The effect of volatile anesthetics on emergence agitation in adults remains unclear. We compared the degree of emergence agitation between desflurane and sevoflurane anesthesia in adults undergoing thyroid surgery. Findings: One hundred and sixteen patients with American Society of Anesthesiologists status 1 or 2 were randomized into two groups: the desflurane group (group D) and the sevoflurane group (group S). After induction of anesthesia with fentanyl (1-2 MUg/kg) and propofol (1.5-2.5 mg/kg), tracheal intubation was facilitated with suxamethonium (0.5-1.0 mg/kg). In group D, anesthesia was maintained with desflurane in 66% nitrous oxide and 33% oxygen supplemented with fentanyl when necessary; in group S, sevoflurane was used instead of desflurane. After the end of the surgery, emergence agitation was evaluated with a modified pediatric anesthesia emergence delirium scale (ranging from 0 to 16, with higher scores indicating more severe emergence agitation) before extubation. Time to extubation from the end of the surgery, postoperative pain (evaluated by a numerical rating scale [NRS]), and postoperative nausea and vomiting (PONV) after surgery were examined. The degree of emergence agitation was more severe in group D than in group S (median [interquartile range]: 5 [4-7] vs 4 [2-6], p = 0.008). Time to extubation, NRS scores, and PONV rates were similar between the two groups. Conclusions: Desflurane anesthesia worsened emergence agitation as compared with sevoflurane in adult patients undergoing thyroid surgery, but did not affect time to extubation, postoperative pain, or PONV. Trial registration: UMIN000014215. PMID- 29457081 TI - Anesthetic management of a patient with narcolepsy by combination of total intravenous and regional anesthesia: a case report. AB - Narcolepsy is a neurological disease characterized by excessive daytime sleepiness, cataplexy, and/or a sudden loss of muscle tone due to malfunction of the orexinergic system, which may cause delayed emergence from general anesthesia. We report a successful anesthetic management of 24-year-old female narcoleptic patient undergoing left anterior cruciate ligament reconstruction. Anesthesia was induced and maintained with total intravenous anesthesia (TIVA) using propofol and remifentanil. Ultrasound-guided left femoral nerve block was also performed with 0.375% ropivacaine 20 ml. Acetaminophen 1000 mg was intravenously administered as part of a multimodal analgesia. After the surgery, the trachea was extubated 9 min after termination of TIVA, and then, the patient correctly responded to verbal commands. The postoperative course was uneventful without any narcoleptic symptoms. PMID- 29457082 TI - Factors affecting extubation time following pediatric ambulatory surgery: an analysis using electronic anesthesia records from an academic university hospital. AB - Background: In pediatric general anesthesia, our goal should be quicker extubation to facilitate rapid turnover in the operating room without compromising on safety and quality of anesthesia. Although many studies have focused on improving safety and pursuing a higher quality of recovery, factors related to anesthesia emergence remain unclear. We must, therefore, identify factors that influence the process of emergence from general anesthesia in children. Findings: We retrospectively examined 148 children (aged 1-6 years, American Society of Anesthesiologists physical status: 1-2) who had undergone <2 h of ambulatory surgery. Clinical measures included time from the end of surgery to extubation (extubation time), age, height, weight, surgical time, mean indirect blood pressure during surgery, mean heart rate during surgery, mean end tidal carbon dioxide during surgery (mETCO2), mean body temperature during surgery (mBT), and total amount of fentanyl. Anesthetic procedures involved sevoflurane or propofol. Multiple regression analysis revealed that mETCO2 (p < 0.01) and mBT (p < 0.01) were independent clinical factors associated with extubation time following pediatric ambulatory surgery. Conclusions: This study of 148 pediatric patients demonstrated that anesthesia emergence may be associated with mBT and mETCO2 following pediatric ambulatory surgery. These results show that perioperative vital signs are important in the prevention of delayed emergence for pediatric patients. PMID- 29457083 TI - Risk factors for rescue analgesic use on the first postoperative day after upper limb surgery performed under single-injection brachial plexus block: a retrospective study of 930 cases. AB - Background: Postoperative pain management after upper limb surgery is important for preventing adverse events that can prolong hospital stay and cause readmission. This study aimed to identify the risk factors associated with rescue analgesic use on the first postoperative day after upper limb surgery performed under single-injection brachial plexus block (BPB). Findings: We retrospectively analyzed records from 930 patients who underwent upper limb surgery under a single-injection BPB. Postoperatively, patients were administered oral loxoprofen regularly and rescue analgesics when analgesia was insufficient. We assessed the association between patient, surgical information, and rescue analgesic use on the first day after surgery (from 7:00 PM on the day of surgery to 7:00 AM on the first postoperative day), using a logistic regression model. Multivariate analysis revealed a significant association between rescue analgesic use and bone surgery, in particular, osteotomy, ligament repair and reconstruction, osteosynthesis, treatment for an amputated digit, and surgical duration. Conclusion: Bone surgery (osteotomy, ligament repair and reconstruction, osteosynthesis, treatment for an amputated digit) and a longer operative time were risk factors for rescue analgesic use for treating postoperative pain after upper limb surgery performed under single-injection BPB. PMID- 29457084 TI - Right ventricular functional assessment by three-dimensional transesophageal echocardiography is useful for withdrawal from a right ventricular assist device: a case report. AB - Right ventricular assist device (RVAD) implantation is one type of surgical treatment used for right heart failure. It is important to assess right ventricular (RV) function precisely when RVAD withdrawal is considered. Although assessment of RV function is difficult due to its complicated shape and contraction pattern, the volumetric analysis method of three-dimensional (3D) transesophageal echocardiography (TEE) has been developed and is useful for this task. We report the case of a 79-year-old man who successfully underwent RVAD withdrawal and evaluation using 3D TEE. 3D TEE had an important role in determining the timing of withdrawal from RVAD in this case. PMID- 29457085 TI - A case in which a capnometer was useful for diagnosing laryngospasm following administration of sugammadex. AB - Background: Sugammadex has been reported to cause upper-airway obstruction, such as laryngospasm or bronchospasm. These two conditions are treated using different approaches, but the differential diagnosis is difficult. Case presentation: We describe a case in which general anesthesia was administered via endotracheal intubation, in combination with brachial-plexus block, for arthroscopic surgical treatment of a rotator-cuff tear caused by recurrent shoulder dislocation. The total dose of rocuronium administered was 90 mg, and the last dose of 10 mg was given 15 min before the end of the surgery. Sugammadex was intravenously administered at 100 mg to reverse the effect of rocuronium after the operation ended. After extubation in this case, we placed a mask firmly around the patient's mouth, and thus, there was no air leakage around the mask. We detected upper-airway obstruction that was presumably attributable to administration of sugammadex. The end-tidal carbon dioxide (EtCO2) concentration was undetectable on a capnometer. Although 100% oxygen was administered at 10 L/min via a facemask, oxygen saturation (SpO2) decreased to approximately 70%. With suspected onset of laryngospasm, continuous positive airway pressure with 100% oxygen at 10 L/min was started at 30 cm H2O. The patient's airway obstruction resolved after a short time. Conclusion: The use of a capnometer facilitated the diagnosis of laryngospasm and allowed us to administer appropriate treatment after administration of sugammadex. PMID- 29457086 TI - Spinal cord infarction following epidural and general anesthesia: a case report. AB - Background: Epidural anesthesia is widely used for postoperative analgesia and rarely causes permanent neurological complications. We report a case of paraplegia following abdominal surgery under combined epidural/general anesthesia. Case presentation: A 75-year-old woman underwent a scheduled abdominal total hysterectomy and bilateral salpingo-oophorectomy for suspected endometrial cancer. In the operating room, an epidural catheter was inserted at T11/12 while the patient was conscious. The needle entered smoothly, with no observed bleeding, paresthesia, or pain, and general anesthesia was induced. During surgery, 4 mL of 0.25% levobupivacaine and 0.1 mg of fentanyl were administered via the epidural catheter, and a solution of 2.5 MUg/mL fentanyl and 0.2% levobupivacaine was continuously infused at 4 mL/h for postoperative analgesia. The patient promptly regained consciousness and could move her bilateral lower extremities without difficulty upon leaving the operating room. During the first postoperative night, she complained of an absence of sensation and weakness in the lower extremities. By the morning of the second postoperative day, she had developed paralysis and sensory losses associated with touch, temperature, pinprick, and vibration below T5. The epidural infusion was stopped. Magnetic resonance imaging (MRI) revealed a hyperintense area of the thoracic cord from T8 to T11, and spinal cord infarction was suspected. Ossification of the yellow spinal ligaments between T11 and T12, resulting in thoracic canal stenosis and thoracic spinal cord compression, were observed. Notably, the epidural catheter was inserted at the same site where the thoracic canal stenosis was present. Conclusions: Permanent neurological complications of epidural anesthesia are rare. Studies of neurological complications after epidural/spinal anesthesia have noted the possibility of spinal anomalies, such as lumbar stenosis, in relation to neurological complications after epidural/spinal anesthesia. In this case, the onset of spinal cord infarction may have occurred coincidentally with catheter insertion into the site of existing spinal stenosis. Therefore, it is important to evaluate lower extremity symptoms and consider spinal disease before administering epidural anesthesia. Spinal cord infarction may be prevented by preoperatively identifying spinal lesions using computed tomography or MRI in cases of suspected spinal disease. PMID- 29457087 TI - Remifentanil for sedation and analgesia during awake division of tongue flap in children: a report of two cases. AB - Background: The tongue flap is an accepted treatment method for cleft palate repair. Orotracheal or nasotracheal intubation using a fiberoptic scope is preferred for the division of the tongue flap. We report two cases of tongue flap division in which the patients received adequate sedation and analgesia without tracheal intubation. Case presentation: Twelve- and 13-year-old male patients were treated at our hospital for tongue flap division, performed as part of a cleft palate repair. We planned to divide the tongue flap under sedation with remifentanil (1 MUg/kg/min continuous infusion) and local anesthesia, followed by induction of general anesthesia, and orotracheal intubation after the tongue flap was divided. During the procedure, patients were breathing spontaneously and were cooperative. Patients were able to follow the surgeons' verbal cues to thrust out the tongue during the procedure, so that the surgeons could easily insert the sutures. Conclusions: During the division of the tongue flap in two children, excellent sedative and analgesic effects were achieved using continuous remifentanil infusion. PMID- 29457088 TI - Successful pulmonary embolectomy for massive pulmonary embolism during pregnancy: a case report. AB - Background: Pulmonary embolism (PE) resulting from venous thromboembolism is a leading cause of maternal mortality in pregnancy. In patients with massive PE and hemodynamic instability, the treatment options often considered are thrombolytics, inferior vena caval filters, or embolectomy. We report here the case of a patient with massive PE at 28 weeks' gestation, who underwent emergency pulmonary embolectomy via cardiopulmonary bypass. Case presentation: A 35-year old primigravida with a history of massive PE at 25 weeks of gestation was referred to our hospital at 28 weeks of gestation, following treatment failure after insertion of an inferior vena cava filter and heparin administration. Emergency thrombectomy was performed, and intracardiac echography was used for intraoperative fetal heart rate monitoring. However, the patient developed hemodynamic collapse following anesthesia induction; hence, emergency cardiopulmonary bypass (CPB) was performed via median sternotomy. Thrombectomy and tricuspid valve plication were performed under cardiac arrest. After confirming postoperative hemostasis, heparin administration was resumed. At 40 weeks of gestation, labor was induced under epidural analgesia. Both mother and child were discharged with no complications. Conclusion: In conclusion, intracardiac echography is useful for fetal heart rate monitoring during emergency cardiac surgery in pregnancy. Careful CPB management is important to maintain uteroplacental blood flow. Although there is no consensus on the delivery methods in such cases, epidural analgesia during labor was useful in reducing cardiac load and wound traction. PMID- 29457089 TI - A case series of continuous paravertebral block in minimally invasive cardiac surgery. AB - Background: Minimally invasive cardiac surgery (MICS), via minithoracotomy, is thought to be a fast track to extubation and recovery after surgery. For this, good coverage analgesia is essential. Epidural anesthesia, a standard technique for thoracic surgery, has high risk of complications, such as epidural abscess and spinal hematoma in open-heart surgery. Based on the hypothesis that continuous paravertebral block (CPVB), a less invasive regional anesthetic technique, is safe and effective in open-heart surgery, we applied CPVB to MICS with thoracotomy. Findings: To assess whether CPVB could be used in open-heart surgery with fewer potential complications, we investigated our medical records of the 87 adult patients who underwent MICS at Akashi Medical Center, Hyogo, Japan, between March 2009 and May 2016. We collected data of CPVB-related complications, postextubation respiratory failure, duration of intubation, and other analgesic use from hospital clinical records. We observed no severe CPVB related complications, such as hematoma, neuropathy, or abscess. PT-INR longer than 1.1 was associated with CPVB-related minor bleeding. Forty-three patients (47.4%) were extubated within 1 h after surgery, and there were no postextubation respiratory failures in any patients. Conclusions: We observed no cases of severe CPVB-related complications or postextubation respiratory failure in any of our patients who underwent MICS. Preoperative prolongation of PT-INR was associated with CPVB-related minor bleeding. PMID- 29457090 TI - Conscious sedation with dexmedetomidine for implantation of a phrenic nerve stimulator in a pediatric case of late-onset congenital central hypoventilation syndrome. AB - Patients with congenital central hypoventilation syndrome (CCHS) develop alveolar hypoventilation resulting from a failure of central ventilatory control. Late onset CCHS (LO-CCHS), which may be precipitated by severe respiratory infection or exposure to sedatives or general anesthesia, presents after the neonatal period. Since CCHS patients require lifelong mechanical-assisted ventilation, in western countries, diaphragm pacing is used to provide adequate alveolar ventilation and oxygenation during rest and daily activities. The main anesthesia related concern regarding CCHS is postoperative respiratory failure or apnea, and anesthetic agents should be minimized to avoid further respiratory depression after surgery. A 5-year-old girl with LO-CCHS was referred to our hospital for implantation of a phrenic nerve stimulator for diaphragm pacing. Respiratory infection triggered the need for permanent nocturnal ventilator support at age 3 years and tracheotomy was performed at age 4 years. Repeated self-dislodgement of the ventilator tube led to hypoxic ischemic encephalopathy. The patient was thought to require mechanical ventilation under minimum sedation and pain management during the early postoperative period. The co-administration of dexmedetomidine and morphine provided effective conscious sedation with protection of the surgical site and without adverse events. She was discharged from the intensive care unit with a home ventilator at 3 days post-operation. PMID- 29457091 TI - Factors affecting the early post-operative prognosis in morbidly obese surgical patients after laparoscopic sleeve gastrectomy - a retrospective cohort study. AB - Background: The number of morbidly obese patients who have undergone bariatric surgery has been gradually increasing in Japan. These obese patients are often complicated with metabolic, cardiac, respiratory, and other diseases. The aim of this study was to analyze the perioperative clinical course in a retrospective cohort with respect to the utility of anesthesia management in order to prevent longer hospital stays after surgery. Findings: Sixty-seven morbidly obese patients who had undergone sleeve gastrectomy were divided into two groups, based upon the duration of postoperative hospital stay; group S was comprised of the patients who were discharged within 5 days after surgery (n = 57) and group L was comprised of those who were discharged after 6 days or more (n = 10). The mean duration of the hospital stay was 4.8 +/- 0.4 days and 7.8 +/- 1.4 days in groups S and L, respectively. Multivariate logistic regression analysis showed that prolonged anesthesia was a predictor of a longer postoperative hospital stay (p < 0.05). While the difference in BMI was not significantly different, the percentage of patients with BMI >= 50 was 12 and 30% in groups S and L, respectively. Conclusions: Longer duration of anesthesia affected the duration of postoperative hospital stay in morbidly obese patients undergoing sleeve gastrectomy. In addition, patients with BMI >= 50 might be at risk of longer hospitalization after surgery.

PMID- 29457093 TI - Neutrophil to lymphocyte ratio and platelet to lymphocyte ratio are superior to other inflammation-based prognostic scores in predicting the mortality of patients with gastrointestinal perforation. AB - Background: The neutrophil to lymphocyte ratio (NLR) is gaining interest as an independent predictor of survival in patients with various clinical conditions. No study to date has reported an association between inflammation-based prognostic scores, including the Glasgow Prognostic Score (GPS), NLR, platelet to lymphocyte ratio (PLR), Prognostic Nutritional Index (PNI), and Prognostic Index (PI), and mortality in patients with gastrointestinal perforation (GIP). We compared the prognostic value of these measures. Findings: A total of 32 patients with GIP were retrospectively enrolled. Patients were assessed according to the GPS, NLR, PLR, PI, and PNI. Multivariate analyses were performed to identify variables associated with mortality. Receiver operating characteristic (ROC) analyses were also performed. Overall survival rates (in-hospital mortality) were calculated using the Kaplan-Meier method, and differences in survival rates between groups were compared by the log-rank test. Multivariate analysis of significant variables revealed NLR (HR 1.257, 95% CI 1.035-1.527, P = 0.021) and PLR (HR 1.004, 95% CI 1.001-1.007, P = 0.016) at the time of admission to the intensive care unit to be independently associated with in-hospital mortality. AUC analysis revealed Sequential Organ Failure Assessment-Glasgow Coma Scale (SOFA-GCS) (0.73) to be superior to NLR (0.57) and PLR (0.58) for predicting mortality, and a high SOFA-GCS score was associated with reduced overall survival (P < 0.05). Conclusions: NLR and PLR were superior to other inflammation-based prognostic scores in predicting the mortality of patients with GIP. PMID- 29457094 TI - Clinical anatomy of the cephalic vein for safe performance of venipuncture. AB - Background: The aims of this study were to elucidate why the cephalic vein provides a reliable cannulation site from a morphological viewpoint and identify an effective landmark for avoiding injury to the superficial branch of the radial nerve (SBRN), allowing for safe venipuncture of the cephalic vein. Findings: We examined 32 forearms and wrists from 18 cadavers. The cephalic vein was a constant structure containing a branch communicating with a collateral vein of the deep palmar arch via the first dorsal interossei muscle. The metacarpal vein from the medial two digits flowed into the cephalic vein. The venous confluence formed 5.8 +/- 1.2 cm proximal to the radial styloid process. The SBRN passed 0.4 +/- 0.3 cm volar to the venous confluence. The distance between the venous confluence and subcutaneous emergence of the SBRN was 2.6 +/- 1.0 cm. Conclusions: These observations suggest that the cephalic vein is a constant structure that serves as a drainage vein of the hand and provides a reliable cannulation site in the forearm. The venous confluence may serve as a novel landmark to predict the running course of the SBRN. PMID- 29457095 TI - Iatrogenic carpal tunnel syndrome induced by wrist extension for placement of an indwelling radial artery catheter: a case report. AB - A 38-year-old man with pancreatic cancer was scheduled to undergo pancreaticoduodenectomy. He had an unremarkable past medical history. After inducing general anesthesia, a left radial arterial catheter was successfully placed at first attempt. A wrist splint was used to obtain good arterial pulse waveforms. After the operation, he was transferred to the intensive care unit. The radial artery catheter was removed on the fourth postoperative day. He experienced numbness and a tingling sensation in the left thumb, the second and third fingers, and the lateral half of the fourth finger. He was diagnosed with carpal tunnel syndrome. Diagnostic imaging revealed a swollen median nerve, but no hematoma or injury. Some studies have suggested that excessive extension of the wrist may cause neuropathy. We recommend that patients' wrists not be over extended, even if good arterial waveforms cannot be obtained. PMID- 29457097 TI - Successful use of femoral nerve block with dexmedetomidine for fracture fixation of an intracapsular fracture of the femoral neck in a patient with severe aortic stenosis: a case report. AB - We described a case in which femoral nerve block (FNB) and lateral femoral cutaneous nerve block (LFCNB) with dexmedetomidine (DEX) was useful for open reduction and internal fixation (ORIF) of a femoral neck fracture in a patient with severe aortic stenosis. Cardiac surgery had been recommended but was declined by the patient. Thus, ORIF was selected because of the patient's concomitant severe aortic stenosis. The anesthesia method used was FNB plus LFCNB with DEX, which achieved adequate local anesthesia. DEX was used to avoid respiratory depression because this patient has pulmonary hypertension. This patient had been sedative up to the end of surgery. Total operating time was 51 min, and the patient's hemodynamics were stable throughout the perioperative period. There were no complications. In this case, anesthesia using a nerve block with DEX contributed to the safety of noncardiac surgery in a patient with severe cardiac disease under conservative treatment during the perioperative period. PMID- 29457096 TI - Effect of Goreisan, a traditional Japanese Kampo medicine, on postoperative nausea and vomiting in gynecological patients. AB - Background: Goreisan, a traditional Japanese Kampo medicine, may prevent postoperative nausea and vomiting (PONV). The purpose of this study was to evaluate the effect of Goreisan on PONV in a high-risk population in a randomized, double-blind, placebo-controlled manner. Findings: Patients undergoing gynecological surgery were randomly allocated to the Goreisan and the control groups. General anesthesia was induced with propofol and remifentanil. After endotracheal intubation, anesthesia was maintained with sevoflurane, fentanyl, and remifentanil. Goreisan 7.5 g dissolved in water (Goreisan group) or water (control group) in a volume of 20 ml was administered through a nasogastric tube approximately 1 h before completion of surgery. The primary outcome of this study was the incidence of PONV during the first 2 h after extubation. In the interim analysis, it was apparent that Goreisan has no effect. Therefore, we discontinued recruiting patients and present results based on data from 83 patients. The incidence of PONV during the first 2 h after extubation was 45% in the Goreisan group (n = 40) and 46.5% in the control group (n = 43) (p = 0.89). There was no significant difference in PONV incidence or severity during the first 24 h post-extubation. Conclusion: Goreisan has little potency in preventing PONV in high-risk patients. PMID- 29457098 TI - Esophageal submucosal hematoma developed after endovascular surgery for unruptured cerebral aneurysm under general anesthesia: a case report. AB - Background: Esophageal submucosal hematoma is a rare complication after endovascular surgery. We report a case of an esophageal submucosal hematoma which may have been caused by rigorous cough during extubation. Case presentation: A 75 year-old woman underwent endovascular treatment for unruptured cerebral aneurysm under general anesthesia. The patient received aspirin and clopidogrel before surgery and heparin during surgery. Activated clotting time was 316 s at the end of surgery. Protamine was not administered and continuous infusion of argatroban was started after surgery. She had a rigorous cough during removal of the tracheal tube and reported retrosternal discomfort postoperatively. She developed hemorrhagic shock after massive hematemesis. A diagnosis of esophageal submucosal hematoma was made by endoscopic examination and computed tomography. Hemostasis was achieved by compression with a Sengstaken-Blakemore tube and endoscopic cauterization. Blood pressure was recovered by blood transfusion. Endoscopic examination performed 7 days after surgery showed that esophageal submucosal hematoma had almost disappeared and slough had adhered to the mucosal laceration. The patient showed good recovery and was discharged 21 days after surgery. Conclusions: Careful extubation and postoperative observation are required in patients receiving antiplatelet and anticoagulant therapy. PMID- 29457099 TI - Perioperative risk factors for acute kidney injury after off-pump coronary artery bypass grafting: a retrospective study. AB - Background: Acute kidney injury (AKI) after cardiac surgery is associated with increased morbidity and mortality. Although morbidity of AKI after off-pump coronary artery bypass grafting (OPCAB) has been investigated, little is known about risk factors for AKI after OPCAB. To identify risk factors for AKI, we examined the association between perioperative variables and AKI after OPCAB. Findings: We reviewed the medical records of consecutive adult patients who underwent isolated OPCAB between January 2010 and February 2013 in a single institute, retrospectively. The primary outcome was the incidence of AKI evaluated using Acute Kidney Injury Network classifications during the first 48 h postoperatively. We investigated preoperative and intraoperative variables, including hemodynamic parameters, as potential risk factors for AKI. The relationship between candidates of AKI and incidence of AKI was examined by multivariate logistic regression analysis.A total of 298 patients were enrolled in this study. Acute kidney injury occurred in 47 patients (15.7%). Multivariate logistic regression analysis showed that intraoperative furosemide administration (odds ratio [OR], 5.163; 95% confidence interval, 2.171 to 12.185; P < 0.001] and diabetes mellitus (OR, 1.954; 95% confidence interval, 1.004 to 3.880; P = 0.049) were significantly associated with AKI. Conclusions: Intraoperative furosemide administration and diabetes mellitus were significantly associated with AKI in patients who had received OPCAB. PMID- 29457100 TI - Differences in heart rate variability may be related to the appearance of postoperative pain in patients undergoing breast cancer surgery. AB - Background: Some reports have highlighted the relationship between heart rate variability (HRV) and the degree of postoperative pain experienced. This study retrospectively examined whether differences in heart rate variability may be related to the appearance of postoperative pain in patients undergoing breast cancer surgery. Findings: We retrospectively analyzed 20 postoperative patients who had no pain immediately upon admission to the post-anesthesia care unit (PACU), divided into two groups: group A (n = 16) had no pain on admission to PACU, remaining pain free upon discharge (12 h after surgery); group B (n = 4) comprised patients with no pain on admission to PACU but who experienced increasing pain requiring intervention in PACU 1 h after surgery. HRV was measured immediately on admission to PACU and 2 h after surgery; this included variables of low-frequency power (LF), high-frequency power (HF), and LF/HF. There were significant differences in HF and LF/HF in group A compared with those in group B on admission to PACU (immediately after arrival): HF, group A, 35.4 +/ 18.1; group B, 64.2 +/- 9.5*; LF/HF group A, 2.7 +/- 2.4; group B, 0.6 +/- 0.2*, *p < 0.05). There was no significant difference in the Numerical rating scale (NRS) between the two groups immediately after admission to PACU. At 1 h after the surgery, NRS in Group B increased, and there were significant differences in NRS values between the two groups 1 h after surgery prior to the use of analgesic agents (NRS, group A, 1.0 +/- 0.9; group B, 4.0 +/- 1.4*, *p < 0.01). Patients in group A required no analgesic agents for at least 12 h after surgery. Conclusions: Lower HF and higher LF/HF values immediately after arrival in PACU were observed in patients remaining pain free for 12 h after surgery compared to patients who experienced increasing postoperative pain 1 h after surgery. The data suggest that differences in HRV may be related to the appearance of postoperative pain. PMID- 29457101 TI - Adhesions in the epidural space caused by frequent epidural blocks. AB - We report a case of adhesions in the epidural space caused by more than 200 times epidural blocks that were observed with epiduroscopy. A 41-year-old man had repeatedly undergone lumbar epidural blocks to treat pain in his leg, resulting in decreased efficacy of the epidural block. We described endoscopic findings that these adhesions were mostly consisted of adhesions formed from the soft connective tissue. PMID- 29457102 TI - Incidence of life-threatening respiratory events after laparoscopic colon surgery with or without continuous respiratory rate monitoring. AB - Background: Respiratory depression (RD) is a critical complication of general anesthesia. The present study investigated the incidence of postoperative life threatening respiratory events after laparoscopic colon surgery in patients observed using continuous respiratory rate monitoring [RM; with oxygen saturation by pulse oximetry (SpO2)] and traditional respiratory monitoring (TM; SpO2 monitoring only). In addition, postoperative incidence rates of RD and desaturation in the RM group were determined. Findings: In this retrospective observational study, medical records of 214 patients who underwent laparoscopic colon surgery were analyzed. A total of 88 patients with RM were observed and compared with 126 patients with TM. Nineteen patients in the RM group were excluded from the final analyses because of incomplete data. No life-threatening respiratory events were observed in the RM group (0/69), whereas two such events (2/126) occurred in the TM group. Incidence rates of postoperative RD and desaturation within 8 h after surgery were 17.1% (12/69) and 24.3% (17/69), respectively, in the RM group. Conclusions: No postoperative life-threatening respiratory events were observed in the RM group. Furthermore, the incidence rates of RD and desaturation were noted to be relatively high. PMID- 29457103 TI - Japanese traditional herbal medicine reduces use of pregabalin and opioids for pain in patients with lumbar spinal canal stenosis: a retrospective cohort study. AB - Background: There has been an increase in the number of Japanese patients with lumbar spinal canal stenosis (LSCS) who complain of chronic pain or motor disturbance in the lower back or extremities. These patients are often treated with anti-convulsive drugs, opioids, antidepressants, acetaminophen, or nonsteroidal anti-inflammatory drugs, all of which can cause side effects. For this reason, Japanese traditional herbal medicine (Kampo) is of interest, because it produces fewer adverse reactions. The aim of this retrospective cohort study was to analyze the effects of Kampo in patients with LSCS. Findings: A total of 151 patients with LSCS were divided into two groups based on treatment with (n = 111, group K) and without (n = 40, group N) Kampo. Use of pregabalin and opioids decreased significantly in group K (p < 0.001). The hazard ratio for opioid discontinuation was 0.220 (p = 0.004) for group N vs. group K, while that for pregabalin and antidepressants discontinuation were 0.589 (p = 0.202) and 0.509 (p = 0.377), respectively. The mean duration of hospital visits and treatment did not differ between the groups, but the number of dropouts was significantly higher in group N (p < 0.0001). The hazard ratio for patient dropout was 4.118 (p = 0.001) for group N vs. group K. Conclusions: Kampo led to discontinuation of opioid use for pain in patients with LSCS, and patients who were treated with Kampo were more likely to continue treatment. PMID- 29457104 TI - Left subclavian artery malperfusion due to thoracic outlet syndrome during total vertebrectomy for invasive lung cancer: a case report. AB - Thoracic outlet syndrome (TOS) can interrupt blood flow to upper limbs by vascular compression. We report a case of a 52-year-old man who presented left subclavian artery malperfusion due to TOS during total vertebrectomy (Th2-4) in the prone position for invasive lung cancer. At the time of resection of the vertebral bodies, his left radial systolic blood pressure had begun to drop intermittently and we noticed an interarm pressure difference. Accordingly, we began to monitor the right radial artery pressure and found that only the left radial artery pressure decreased as a result of compressive force from the surgical site. The operation was continued with intermittent malperfusion of the left arm, and when it was prolonged, we asked the surgeons to release the compression. No symptoms of ischemia or nerve injuries in the left arm were observed after the surgery. Retrospective review of his preoperative enhanced computed tomography images suggested a slightly compressed left subclavian artery in the costoclavicular space. Combination of the prone position and a specific upper limb position may be a risk factor for intraoperative TOS. An interarm blood pressure difference is a clue to detect accidental arterial TOS during general anesthesia.

AB - Background: Coronary artery to pulmonary artery fistula is an unusual vascular anomaly, and the shunt ratio of this fistula is usually small. Case presentation: We report anesthetic management of a 55-year-old female with annuloaortic ectasia, aortic valve regurgitation, and coronary artery to pulmonary artery fistula undergoing radical repair. We calculated the left-to-right shunt ratio after placement of a pulmonary artery catheter and found that the ratio was unexpectedly high. Thus, we explored the presence of another shunt by intraoperative transesophageal echocardiography and found patent ductus arteriosus undiagnosed before operation. Conclusions: A combination of a pulmonary artery catheter and transesophageal echocardiography is useful to explore the presence of another shunt, such as patent ductus arteriosus during anesthesia. PMID- 29457105 TI - Collaborating with interventional pulmonology in managing a massive tracheoesophageal fistula that extends from cricoid to carina: a case report. AB - Tracheoesophageal fistulas (TEF) present a perioperative management challenge. A 62 year-old man with esophageal carcinoma presented with a large tracheoesophageal fistula extending most of the trachea. Previously, the patient had two overlapping esophageal and one tracheal stent placed, but he developed progressive tracheal disruption due to esophageal stent perforation near the level of the cricoid. This case describes the anesthetic management of tracheal stent placement for an expanding TEF. Management included a spontaneous breathing inhalation induction followed by ventilation through a supraglottic device laryngeal mask airway (LMA). Finally, during rigid bronchoscopy, a combination of bag ventilation and jet ventilation was utilized. PMID- 29457107 TI - The ultrasound-guided nerve blocks of abdominal wall contributed to anesthetic management of cholecystectomy in a patient with Becker muscular dystrophy without using muscle relaxants. AB - Becker muscular dystrophy (BMD) is a progressive neuromuscular disorder caused by mutations in the dystrophin gene. The sensitivity to non-depolarizing muscle relaxant in a patient with muscle dystrophy is reportedly higher than that in normal individuals, and the duration of the effect is known to be prolonged. In this report, we present the case of a 58-year-old man with BMD who underwent laparoscopic cholecystectomy for symptomatic cholelithiasis under total intravenous anesthesia without the use of muscle-relaxant drugs and supplemented with regional anesthesia. Anesthesia was induced and maintained with propofol, remifentanil, and fentanyl; ultrasound-guided bilateral rectus sheath block (RSB) and right-sided subcostal transversus abdominis plane block (TAP) were performed. The procedure required conversion to open surgery because of hard conglutination; intraoperative and postoperative periods were uneventful. Adequate analgesia was maintained after extubation because of the effect of RSB and TAP. PMID- 29457108 TI - Continuous PECS II block for postoperative analgesia in patients undergoing transapical transcatheter aortic valve implantation. AB - It has been reported that PECS II block can alleviate postoperative pain following transapical transcatheter aortic valve implantation (TA-TAVI). However, the effectiveness of continuous PECS II block with catheterization has not yet been reported on the postoperative pain in patients undergoing TA-TAVI. We experienced two cases of TA-TAVI who received PECS II block with catheterization to manage postoperative pain. In the first case, a bolus injection for intraoperative pain and subsequent catheterization were performed before the implantation. However, the patient developed severe pain postoperatively in spite of the continuous block due to displacement of the catheter. In the second case, a bolus injection and the catheterization for the continuous block were performed before and after the implantation, respectively, which provided high-quality pain control. Continuous PECS II block may be useful to control perioperative pain associated with TA-TAVI. The insertion of the catheter after the implantation could be useful to avoid its displacement during the surgery. PMID- 29457109 TI - Perioperative management of a pregnant patient with mediastinal tumor complicated by tuberculosis. AB - Mediastinal tumor in a pregnant woman, which had needed a multidisciplinary approach, was further complicated by tuberculosis. The clinical course of the current patient was very complicated. A 37-year-old female at 18 weeks of gestation with a mediastinal tumor was referred to our hospital due to dyspnea and orthopnea. The tumor compressed the left main bronchus causing bronchial stenosis. She was diagnosed with primary mediastinal large B-cell non-Hodgkin's lymphoma. Delivery after 24 gestational weeks with ongoing chemotherapy was planned by a multidisciplinary team comprising obstetricians, anesthesiologists, neonatologists, and hematologists. Her symptoms improved with chemotherapy; however, she was later diagnosed with tuberculosis leading to chemotherapy interruption to treat tuberculosis. The following confirmation by negative sputum smear microscopy, an elective cesarean section with spinal anesthesia was performed at 33 weeks of gestation, and she safely delivered a female infant. At postoperative day 23, she died due to cardiopulmonary arrest, following an irreversible coma subsequent to brain metastasis of malignant lymphoma. The infant died of respiratory failure at postoperative day 18. This case illustrates several implications, such as the necessity of a thorough systemic examination and treatment approaches for mothers and neonates with suspected tuberculosis during the perioperative period, for considering similar cases with neoplasms.

PMID- 29457111 TI - Mortality and physical status at hospital discharge in Japanese elderly critically ill patients: a single-center retrospective study. AB - Background: Because there is ongoing population aging, the age of patients admitted to the intensive care unit (ICU) is also higher. However, the evidence about outcomes in elderly patients is insufficient in Japan. Therefore, we conducted a retrospective study. Method: The study participants were consecutive patients who were admitted to our ICU and received mechanical ventilation for more than 24 h. We divided the patients into two groups, according to age. Patients in group A were 74 years old or younger, and those in group B were 75 years old or older. The major outcome was in-hospital mortality. Findings: Two hundred and twenty patients met the inclusion criteria. There were 118 patients in group A and 102 patients in group B. The overall hospital mortality in both groups were similar (19 vs. 25%, p = 0.23). The proportion of patients who were discharged home and had good physical status at hospital discharge in group A were significantly higher than that in group B (72 vs. 37%, p < 0.0001; 91 vs. 74%, p = 0.004, respectively). Conclusion: The elderly population were associated with a twofold increase in the risk of discharged not to the home compared with others. PMID- 29457112 TI - Anesthetic management during a cesarean section in a patient with cleidocranial dysplasia: a case report. AB - Background: Cleidocranial dysplasia is a type of skeletal dysplasia, which is primarily characterized by delayed ossification of skeletal structures. It causes facial and oral abnormalities, resulting in difficult airway management and neuraxial anesthesia. Case presentation: The patient was a 24-year-old primipara (height 138 cm, weight 42 kg) with a hypoplastic right clavicle, patent fontanelles, dental malalignment, and a high palate. She was diagnosed with cleidocranial dysplasia at birth, although gene examination has not been performed. The fetus was confirmed to have short limbs and large fontanelles during an examination performed at 28 weeks gestation, suspected to have cleidocranial dysplasia. The mother was scheduled for a cesarean section at 37 weeks and 1 day due to cephalopelvic disproportion. Preoperative radiography and magnetic resonance imaging revealed no vertebral and spinal abnormalities, which allowed combined spinal-epidural analgesia (CSEA) to be performed. The surgery was safely concluded under CSEA with no intraoperative respiratory or circulatory problems. Conclusions: Patients with cleidocranial dysplasia exhibit facial, oral abnormalities, and often vertebral abnormalities. Imaging assessments before neuraxial anesthesia and careful preparation for airway management are required. PMID- 29457113 TI - Pulmonary embolism caused by ovarian vein thrombosis during cesarean section: a case report. AB - Background: Ovarian vein thrombosis is a rare complication of pregnancy. The representative complaints of patients with ovarian vein thrombosis are abdominal pain and fever. In some cases, however, fatal pulmonary embolism may develop. We report a case of pulmonary embolism presenting with severe hypotension and loss of consciousness during cesarean section possibly caused by ovarian vein thrombosis. Case presentation: A 25-year-old woman at 38 weeks 4 days of gestation was scheduled for repeat cesarean section. Her past history was unremarkable, and the progress of her pregnancy was uneventful. She did not experience any symptoms indicative of deep vein thrombosis. Cesarean section was performed under spinal anesthesia, and a healthy newborn was delivered. After removal of the placenta, she suddenly developed dyspnea, hypotension, and loss of consciousness with decreased peripheral oxygen saturation. Blood pressure, heart rate, and oxygen saturation recovered after tracheal intubation and mechanical ventilation with oxygen. Postoperative computed tomography revealed no abnormality in the brain or in the pulmonary artery, but a dilated right ovarian vein with thrombi, extending up to the inferior vena cava, was found. A diagnosis of pulmonary embolism caused by ovarian vein thrombosis was made, and heparin was administered. The tracheal tube was removed on the first postoperative day. Her postoperative course was uneventful, and she was discharged with no complications. Conclusion: Fatal pulmonary embolism might be caused by ovarian vein thrombosis during cesarean section. Careful and continuous observation of the patient after delivery and prompt treatment are important. PMID- 29457114 TI - A pediatric case developing critical abdominal distension caused by a combination of humidified high-flow nasal cannula oxygen therapy and nasal airway. AB - Background: We describe a pediatric patient who suffered from critical abdominal distention caused by a combination of humidified, high-flow nasal cannula (HHFNC) oxygen therapy and nasal airway. Case presentation: A 21-month-old boy with a history of chronic lung disease was admitted to the intensive care unit (ICU). Immediately after admission, his airway was established using a tracheal tube and mechanical ventilation was started. Five days after the commencement of mechanical ventilation, finally, his trachea was extubated. Immediately after extubation, HHFNC therapy at 20 L/min with an FiO2 of 0.35 was applied. However, severe stridor was observed, then a nasal airway was placed in the left nostril. However, he became restless. Critical abdominal distention was observed. A subsequent chest X-ray revealed that the nasal airway was placed too deeply, and the gastrointestinal air was severely accumulated. Immediately, the nasal airway was removed, and HHFNC flow was reduced to 10 L/min. Frequent suctioning and continuous gastric drainage were required, which achieved gradual improvement of respiratory condition. Conclusions: We need to recognize that HHFNC therapy is one of the positive pressure ventilation system. Therefore, HHFNC therapy might cause the similar adverse events to noninvasive pressure ventilation. PMID- 29457115 TI - Comparison of inflationary non-invasive blood pressure (iNIBP) monitoring technology and conventional deflationary non-invasive blood pressure (dNIBP) measurement in detecting hypotension during cesarean section. AB - Background: The Nihon Kohden linear inflationary non-invasive blood pressure (iNIBP) monitoring technology is an oscillometric device that measures blood pressure by detecting oscillations during inflation. Systolic blood pressure can be recorded without overinflating the cuff higher than the true systolic pressure. Thus, total time taken for inflation and deflation is shorter than that by the conventional deflation devices. In this study, the ability of iNIBP to detect maternal hypotension during cesarean section faster than deflationary non invasive blood pressure (dNIBP) monitoring devices under clinical settings was evaluated prospectively. Methods: A prospective study of singleton planned cesarean sections at a tertiary center was conducted from August 2015 to April 2016. The combined spinal-epidural anesthesia (CSEA) technique through a single puncture was performed for cesarean section at the center where the study was carried out. An iNIBP cuff was placed on the same arm as the intravenous line, and a dNIBP cuff was placed on the other arm. Due to left uterine displacement by approximately 10 degrees tilt of OR table, hypotension in this study was defined as systolic pressure of 107 mmHg or less, when measured in the left arm, which was about 10 cm lower, and pressure of 92 mmHg or less in the right arm which was about 10 cm higher. This setup was done to evaluate which device detected hypotension faster under clinical settings. A two-tailed Z test was performed to statistically analyze the difference between iNIBP and dNIBP measurement results. Results: One hundred singleton planned cesarean deliveries under CSEA were included after 36 weeks of gestation. Out of the 100, 76 women (76%) experienced maternal hypotension. Of these, iNIBP detected hypotension faster than dNIBP in 47 cases (61.8%). Conclusion: It was found that iNIBP detected hypotension faster than conventional dNIBP without compromising the reliability of measurement. This may lead to early treatment of maternal hypotension and prevention of adverse events related to the mother and the fetus. PMID- 29457116 TI - A spinal cord infarction that occurred after laparoscopic gastrectomy performed under general anesthesia and epidural analgesia. AB - Background: Spinal cord infarction (SCI) after epidural anesthesia is quite rare. Although most cases of perioperative SCI are associated with aortic, cardiac, or spinal surgery, and/or abnormal preoperative conditions, such as spinal stenosis or hypercoagulopathy, intraoperative events, such as severe hypotension or epidural puncture and catheterization, can be contributory factors. Case presentation: A 52-year-old male was underwent laparoscopic gastrectomy. Before induction of general anesthesia, an epidural catheter was placed without any problems. The patient had no pain and no complaint just after the operation, but suddenly complained of back pain and anuria, and could not move either of his lower limbs 30 h after the operation. As we thought that the incident would be caused by the migration of the epidural catheter into the subarachnoid space, we removed the catheter, but there was no recovery of the symptoms even 20 h later. The magnetic resonance imaging (MRI) scan showed no hematoma in the epidural space but an abnormal signal within the spinal cord, extending from the Th3 to Th8 levels, which was consistent with the SCI. Unfortunately, the patient's recovery from the paraplegia and abnormal sensation was poor. Conclusions: When a patient complains of lower limb muscle weakness and/or abnormal sensations, it is important to perform an MRI examination and treatment as early as possible to avoid permanent paraplegia, especially after epidural puncture and catheterization. PMID- 29457117 TI - Goal-directed therapy reduces fluid balance while maintaining hemodynamic stability in intraoperative management of pancreaticoduodenectomy: a retrospective comparative study. AB - Background: Goal-directed therapy (GDT) is beneficial for surgical patients, especially for those undergoing high-risk surgery. However, little has been reported on the hemodynamic effects of GDT in extensive surgery. We conducted a study to determine the impact of GDT on intraoperative management of extensive surgery. Findings: We retrospectively collected data from 90 patients who underwent pancreaticoduodenectomy: 44 who received intraoperative GDT (GDT group) and 46 who received conventional hemodynamic management (control group). Intraoperative use of fluids and catecholamines and physiologic variables, including mean arterial pressure, heart rate, and urine output, were compared. We also examined the correlation between the amount of fluid administered and urine output. The amount of fluid administered was comparable, and urine output was significantly larger in the GDT group than in the control group. Fluid balance was significantly smaller in the GDT group (49.7 versus 61.7 mL/kg; 95% confidence interval, - 19.5 to - 4.6 mL/kg; P = 0.0019). There was a trend toward higher mean arterial pressure in the GDT group despite lower fluid balance. We found a rank correlation between the amount of fluid administered and urine output in the GDT group (rank correlation coefficient, 0.68; P < 0.001), but there was no such correlation in the control group. Conclusions: GDT increased urine output and decreased fluid balance while maintaining hemodynamic stability. The amount of fluid administered and urine output were correlated in the GDT group. PMID- 29457118 TI - Preoperative elevated FDP may predict severe intraoperative hypotension after dural opening during decompressive craniectomy of traumatic brain injury. AB - Purpose: Coagulation disorder and intraoperative hypotension are representative complications of traumatic brain injury which cause worse perioperative outcome. The aim of this study was to survey the relation of coagulation disorder and intraoperative hypotension (IH) during decompressive craniectomy. Method: Patients who underwent emergency decompressive craniectomy due to traumatic brain injury were retrospectively surveyed. The relation between preoperative coagulation date and intraoperative hypotension (systolic blood pressure < 60 mmHg after dural opening) was analyzed. Results: Of 41 patients screened, 12 patients (27.9%) developed IH. Fibrinogen degradation products (314 vs 64.4 MUg/mL; p = 0.01) were significantly higher in the IH group. In contrast, fibrinogen (181 vs 239 mg/dL; p = 0.01) was significantly lower in the IH group. Reduction rate of sBRP before and after dural opening (%) was higher in IH group than in non-IH group (49.1 vs 27.6%: p = 0.001). Conclusions: Preoperative elevated FDP may predict IH after dural opening during traumatic decompressive craniectomy. PMID- 29457119 TI - Effects of glucose-insulin infusion during major oral and maxillofacial surgery on postoperative complications and outcomes. AB - Background: Secretion of hormones, which antagonize the action of insulin, is facilitated in response to surgery, and acute resistance to the action of insulin develops. Our aim is to elucidate the effects of intraoperative glycemic control by glucose-insulin (GI) infusion on postoperative complications and outcomes in major oral and maxillofacial surgery. Findings: Thirty patients aged >= 60 years undergoing a radical operation of oral malignant tumors with tissue reconstruction (>= 8 h) were analyzed. In the GI group, regular insulin was continuously applied with glucose-added acetate Ringer's solution (5-10 g glucose per 500 mL). Blood glucose was adjusted within the target concentration of 80-120 mg/dL. In the control group, combination of acetate Ringer's solution containing 1% (W/V) glucose and lactate Ringer's solution, which contains no glucose, was employed. Perioperative clinical parameters, incidence of hypoalbuminemia, and postoperative complications, i.e., surgical site infection, necrosis of a reconstructed flap, bacteremia, hypotension, or pneumonia, were compared. Both serum total protein and albumin concentrations (postoperative day 1 [Day1]) were higher in the GI group. The mean infusion rate of glucose during surgery (mg/kg/h) was independently associated with the decrease in both serum total protein and albumin concentrations from the control to Day1. No difference was found between the groups in the incidence of postoperative complications and the days required until discharge, except less incidence of hypoalbuminemia in the GI group. Conclusions: Application of additional glucose during major oral and maxillofacial surgery preserved serum albumin concentration. However, it did not lead to less postoperative complications and less days until discharge. PMID- 29457120 TI - Spread of injectate in ultrasound-guided serratus plane block: a cadaveric study. AB - Background: Serratus plane block is a thoracic truncal block that has been proposed as alternatives for analgesia such as epidural anesthesia and paravertebral block for the anterolateral chest wall. Previously, we performed the clinical study about optimal volume of the local anesthetic in serratus plane block. The primary aim of this study was to assess the pattern of distribution of dye into the serratus plane of cadavers after ultrasound-guided serratus plane injection. Findings: Ultrasound-guided serratus plane injection was performed at the level of the fourth rib on the mid-axillary line in nine adult Thiel-embalmed cadavers. In each cadaver, one side was injected with 20 ml of methylene blue dye and the contralateral side with 40 ml. Dissections of the thoracic walls were performed 20 min after the injection. The spread of the dye to intercostal nerves, lateral and medial pectoral nerves, long thoracic nerve, and thoracodorsal nerves was assessed. All T2-T5 intercostal nerves in the 40-ml group and all T3-T4 nerves in the 20-ml group were stained with the dye. A larger number of intercostal nerves was stained in the 40-ml group than that in the 20 ml group. Medial and lateral pectoral nerves were not frequently stained in either group. Conclusions: The range of craniocaudal spread of the injectate was wider in the 40-ml group than that in the 20-ml group after ultrasound-guided serratus plane injection in Thiel-embalmed cadavers. PMID- 29457121 TI - Anesthesia for patients with PTRF mutations: a case report. AB - Background: Polymeraze I and transcript release factor (PTRF) mutations are a newly recognized disease, which cause congenital generalized lipodystrophy associated with myopathy. Case presentation: A 29-year-old man (height 126 cm; weight 22 kg) with a PTRF mutation was scheduled for mandibular dentigerous cystectomy. His primary symptoms were lipodystrophy, myopathy, long QT syndrome, refractory nephrosis, and abnormal lipid metabolism. Defibrillator pads were applied soon after the patient entered the operating room. Anesthesia was induced using continuous administration of dexmedetomidine (4 MUg/kg/h) for 15 min; midazolam (7 mg) was added while monitoring the bispectral index and his vital signs. Remifentanil and rocuronium were administered before endotracheal intubation. The surgeon used local anesthesia, and dexmedetomidine and remifentanil were titrated throughout the surgery. The surgery was performed uneventfully, and the patient was extubated following the administration of sugammadex and flumazenil. Conclusion: Patients with PTRF mutations require careful anesthetic planning. We planned to administer lipid-free, non inhalational agents for the induction and maintenance of anesthesia. The anesthetic method used for this minor surgery was safe and effective. PMID- 29457122 TI - A case of spinal anesthesia in a patient with progressive supranuclear palsy. AB - Progressive supranuclear palsy (PSP) is one of the rare diseases. PSP is characterized by oculomotor dysfunction, postural instability, akinesia, dysarthria, and dysphagia. The major cause of death in patients with PSP is aspiration pneumonia. Considering these complications, spinal anesthesia is useful in patients with PSP. However, the potential harmful effects of spinal anesthesia including neurotoxicity of local anesthetics and neurologic complications for patients with PSP are unclear, because there has been no report. Here, we present spinal anesthesia for a patient with PSP. An 80-year-old man with progressive oculomotor dysfunction, dysphagia, and history of repeated aspiration pneumonia was scheduled for inguinal hernia surgery. Acutely concerning about perioperative pulmonary complications, we performed spinal anesthesia. Fortunately, there was no complication associated with respiration or neural system during perioperative period. We hope our experience and case report will be helpful in specific perioperative anesthetic care for patients with PSP. PMID- 29457123 TI - General anesthesia with propofol for ovarian teratoma excision associated with anti-N-methyl-D-aspartate receptor encephalitis. AB - Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is an autoimmune disorder caused by production of anti-NMDAR antibodies that is often associated with ovarian teratoma and exhibits various manifestations including psychiatric symptoms, seizures, hypoventilation, and autonomic nerve instability. Patients with this disorder who receive early surgical tumor resection along with immunotherapy have better outcome than the rest of the patients. To establish an anesthetic plan, it is important to understand the pharmacological interaction between the anesthetic agents and the disabled NMDAR, because NMDAR is one of the major sites of action for commonly-used anesthetic agents. Herein, we describe two young female patients with anti-NMDAR encephalitis who required surgical resection of ovarian teratoma under general anesthesia using propofol, remifentanil, and fentanyl. In both of these anesthetic courses, neither psychoneuronal modification nor autonomic instability by propofol was evident. Furthermore, propofol has been reported to suppress the effects of ketamine on the posterior cingulate cortices, which is the area of the brain concerned with psychotomimetic activity and neural damage of NMDAR antagonists. Our cases imply that propofol is safely used in patients with anti-NMDAR encephalitis, although it has some pharmacological effects on NMDAR. PMID- 29457124 TI - Dilated aortic root influences pulmonary artery catheter placement in anesthetized patients. AB - Purpose: The placement of a pulmonary artery catheter sometimes needs long time by observing the pressure wave, and several factors have been reported to hinder the placement. In the present study, we examined whether enlargement of the aortic root is associated with longer time for the placement. Method: We examined the time required for the catheter placement. The catheter placement time was defined as the duration of time required for the catheter to float from the CVP position to the pulmonary artery. The catheter placement was performed by one experienced physician. We examined the following factors on the catheter placement time: the patient's age, height, weight, cardiothoracic ratio, tricuspid regurgitation, ejection fraction and the diameter of aortic annulus, sinus of Valsalva, sinotubular junction, and proximal ascending aorta. These diameter values were divided by body surface area (BSA) to equalize among different physical sizes. The data were analyzed by multiple linear regression analysis after univariate analysis. Results: The univariate analysis showed that ejection fraction and aortic annulus/BSA, sinus of Valsalva/BSA, and sinotubular junction/BSA correlated with the catheter placement time (P = 0.079, 0.030, 0.029, and 0.025, respectively). Since the three aortic root values correlated with each other, we chose the sinotubular junction/BSA for the following multivariate analysis, because of the highest P value. The multivariate analysis showed that sinotubular junction/BSA had a significant positive association with the placement time (P = 0.048). Conclusion: The present study showed that enlargement of the aortic root is associated with long placement time of the catheter. PMID- 29457125 TI - Enhanced differentiation of dental pulp cells cultured on microtubular polymer scaffolds in vitro. AB - : Dental caries (tooth decay) is the most common chronic disease. Dental tissue engineering is a promising alternative approach to alleviate the shortcomings of the currently available restorative materials. Mimicking the natural extracellular matrix (ECM) could enhance the performance of tissue engineering scaffolds. In this study, we developed microtubular (~20 MUm diameter) polymethyl methacrylate (PMMA) scaffolds resembling the tubular (~2.5 MUm diameter) structure of dentin, the collagen-based mineralized tissue that forms the major portion of teeth, to study the effect of scaffold architecture on differentiation of mouse dental pulp cells in vitro. Flat (control), plasma-treated solid and microtubular PMMA scaffolds with densities of 240+/-15, 459+/-51 and 480+/-116 tubules/mm2 were first characterized using scanning electron microscopy and contact angle measurements. Dental pulp cells were cultured on the surface of the scaffolds for up to 21 days and examined using various assays. Cell proliferation and mineralization were examined using Alamar Blue and Xylenol Orange (XO) staining assays, respectively. The differentiation of pulp cells into odontoblasts was examined by immunostaining for Nestin and by quantitative PCR analysis for dentin matrix protein 1 (Dmp1), dentin sialophosphoprotein (Dspp) and osteocalcin (Ocn). Our results showed that the highest tubular density scaffolds significantly (p<0.05) enhanced differentiation of pulp cells into odontoblasts as compared to control flat scaffolds, as evidenced by increased expression of Nestin (5.4x). However, mineralization was suppressed on all surfaces, possibly due to low cell density. These results suggest that the microtubular architecture may be a desirable feature of scaffolds developed for clinical applications. Lay Summary: Regenerative engineering of diseased or traumatized tooth structure could avoid the deficiencies of traditional dental restorative (filling) materials. Cells in the dental pulp have the potential to differentiate to dentin-producing odontoblast cells. Furthermore, cell-supporting scaffolds that mimic a natural extracellular matrix (ECM) are known to influence behavior of progenitor cells. Accordingly, we hypothesized that a dentin-like microtubular scaffold would enhance differentiation of dental pulp cells. The hypothesis was proven true and differentiation to odontoblasts increased with increasing density of the microtubules. However, mineralization was suppressed, possibly due to a low density of cells. The results demonstrate the potential benefits of a microtubular scaffold design to promote odontoblast cells for regeneration of dentin. PMID- 29457126 TI - Using Predictive Evaluation to Design, Evaluate, and Improve Training for Polio Volunteers. AB - Background: Predictive Evaluation (PE) uses a four-step process to predict results then designs and evaluates a training intervention accordingly. In 2012, the Sustainable Management Development Program (SMDP) at the Centers for Disease Control and Prevention used PE to train Stop Transmission of Polio (STOP) program volunteers. Methods: Stakeholders defined specific beliefs and practices that volunteers should demonstrate. These predictions and adult learning practices were used to design a curriculum to train four cohorts. At the end of each workshop, volunteers completed a beliefs survey and wrote goals for intended actions. The goals were analyzed for acceptability based on four PE criteria. The percentage of acceptable goals and the beliefs survey results were used to define the quality of the workshop. A postassignment adoption evaluation was conducted for two cohorts, using an online survey and telephone or in-person structured interviews. The results were compared with the end of workshop findings. Results: The percentage of acceptable goals across the four cohorts ranged from 49% to 85%. In the adoption evaluation of two cohorts, 88% and 94% of respondents reported achieving or making significant progress toward their goal. A comparison of beliefs survey responses across the four cohorts indicated consistencies in beliefs that aligned with stakeholders' predictions. Conclusions: Goal statements that participants write at the end of a workshop provide data to evaluate training quality. Beliefs surveys surface attitudes that could help or hinder workplace performance. The PE approach provides an innovative framework for health worker training and evaluation that emphasizes performance. PMID- 29457127 TI - Polyethylenimine-dermatan sulfate complex, a bioactive biomaterial with unique toxicity to CD146-positive cancer cells. AB - We report unique bioactivity of a polycation-polyanion complex with potential utility for cancer therapy. A complex of disulfide-crosslinked polyethyleneimine (CLPEI), a polycation used for gene complexation, and dermatan sulfate (DS), an anionic polysaccharide to shield excessive cationic charge of the former, has toxicity to a specific group of cancer cell lines, including B16-F10 murine melanoma, A375SM human melanoma, and PC-3 human prostate cancer cells. These CLPEI-DS-sensitive cells express CD146, which binds to the complex via interaction with DS. There is a positive correlation between toxicity and intracellular level of CLPEI, indicating that the CLPEI-DS-sensitivity is attributable to the increased cellular uptake of CLPEI mediated by the DS-CD146 interactions. In vitro studies show that CLPEI-DS complex causes G0/G1 phase arrest and apoptotic cell death. In syngeneic and allograft models of B16-F10 melanoma, CLPEI-DS complex administered with a sub-toxic level of doxorubicin potentiates the chemotherapeutic effect of the drug by loosening tumor tissues. Given the unique toxicity, CLPEI-DS complex may be a useful carrier of gene or chemotherapeutics for the therapy of CD146-positive cancers. PMID- 29457128 TI - Evaluation of Hydrogels Presenting Extracellular Matrix-Derived Adhesion Peptides and Encapsulating Cardiac Progenitor Cells for Cardiac Repair. AB - Cell therapy is an emerging paradigm for the treatment of heart disease. In spite of the exciting and promising preclinical results, the benefits of cell therapy for cardiac repair in patients have been modest at best. Biomaterials-based approaches may overcome the barriers of poor differentiation and retention of transplanted cells. In this study, we prepared and tested hydrogels presenting extracellular matrix (ECM)-derived adhesion peptides as delivery vehicles for c kit+ cardiac progenitor cells (CPCs). We assessed their effects on cell behavior in vitro as well as cardiac repair in rats undergoing ischemia reperfusion. Hydrogels presenting the collagen-derived GFOGER peptide induced cardiomyocyte differentiation of CPCs as demonstrated by increased expression of cardiomyocyte structural proteins. However, conditioned media obtained from GFOGER hydrogels showed lower levels of secreted reparative factors. Interestingly, following injection in rats undergoing ischemia-reperfusion, treatment with CPCs encapsulated in nonadhesive RDG-presenting hydrogels resulted in the preservation of cardiac contractility and attenuation of postinfarct remodeling whereas the adhesion peptide-presenting hydrogels did not induce any functional improvement. Retention of cells was significantly higher when delivered with nonadhesive hydrogels compared to ECM-derived peptide gels. These data suggest that factors including cell differentiation state, paracrine factors and interaction with biomaterials influence the effectiveness of biomaterials-based cell therapy. A holistic consideration of these multiple variables should be included in cell biomaterial combination therapy designs.

AB - Introduction: Varying prevalence rates of type 2 diabetes have been observed in different parts of the southern state of Kerala, India which is in an advanced stage of epidemiologic transition. Social patterning is evident in diabetes and therefore it was decided to undertake a study on estimating the prevalence of diabetes and associated social determinants. Methodology: The adopted local self administration unit of the Medical College which is also the field practice area with a population of 25,096 was taken for the study. All the households in the area were visited and the details regarding self reported diabetes was collected after obtaining informed consent and analysis done by multivariate logistic regression. Result: The prevalence of self reported diabetes in this coastal area was found to be low at 7.4%. Type 2 diabetes was also found to occur significantly earlier among the respondents belonging to the below poverty line. Age above 40 years (OR 2 95% CI 1.5-2.7, p=.000), marital status (OR 1.9 95% CI 1.1-2.1, p=.006) presence of comorbidities (OR 635 95% CI 389-969, p=.000), more than 8 years of schooling (OR 0.64 95% CI 0.46-0.86, p=.004), living conditions as represented by presence of household source of drinking water(OR 1.4 95% CI 1.01-1.5) were found to be independent predictors. Though there was increasing trend of diabetes among the forward caste line families after backward logistic regression this disappeared leaving behind the proxy of socioeconomic status, household source of drinking water. Conclusion: Though, the state of Kerala is in an advanced stage of epidemiologic transition, coastal areas are still in the earlier phases of transition with low prevalence of type 2 diabetes mellitus. Higher education and better living conditions are important social determinants of diabetes though further studies are necessary to delineate the impact of economic status and education.

AB - In addition to a multitude of genetic and biochemical alterations, abnormal morphological, structural, and mechanical changes in cells and their extracellular environment are key features of tumor invasion and metastasis. Furthermore, it is now evident that mechanical cues alongside biochemical signals contribute to critical steps of cancer initiation, progression, and spread. Despite its importance, it is very challenging to study mechanics of different steps of metastasis in the clinic or even in animal models. While considerable progress has been made in developing advanced in vitro models for studying genetic and biological aspects of cancer, less attention has been paid to models that can capture both biological and mechanical factors realistically. This is mainly due to lack of appropriate models and measurement tools. After introducing the central role of mechanics in cancer metastasis, we provide an outlook on the emergence of novel in vitro assays and their combination with advanced measurement technologies to probe and recapitulate mechanics in conditions more relevant to the metastatic disease.

The relatively short, simple history of young ocean lithosphere makes it an ideal place to determine the property that defines a plate, yet the remoteness and harshness of the seafloor have made precise imaging challenging. We use S-to-P receiver functions to image discontinuities beneath newly formed lithosphere at the Juan de Fuca and Gorda Ridges. We image a strong negative discontinuity at the base of the plate increasing from 20 to 45 km depth beneath the 0- to 10-million-year-old seafloor and a positive discontinuity at the onset of melting at 90 to 130 km depth. Comparison with geodynamic models and experimental constraints indicates that the observed discontinuities cannot easily be reconciled with subsolidus mechanisms. Instead, partial melt may be required, which would decrease mantle viscosity and define the young oceanic plate.

AB - The United Nations Paris Agreement creates a specific need to compare consequences of cumulative emissions for pledged national commitments and aspirational targets of 1.5 degrees to 2 degrees C global warming. We find that humans have already increased the probability of historically unprecedented hot, warm, wet, and dry extremes, including over 50 to 90% of North America, Europe, and East Asia. Emissions consistent with national commitments are likely to cause substantial and widespread additional increases, including more than fivefold for warmest night over ~50% of Europe and >25% of East Asia and more than threefold for wettest days over >35% of North America, Europe, and East Asia. In contrast, meeting aspirational targets to keep global warming below 2 degrees C reduces the area experiencing more than threefold increases to <10% of most regions studied. However, large areas-including >90% of North America, Europe, East Asia, and much of the tropics-still exhibit sizable increases in the probability of record setting hot, wet, and/or dry events. PMID- 29457134 TI - Trophic signatures of seabirds suggest shifts in oceanic ecosystems. AB - Pelagic ecosystems are dynamic ocean regions whose immense natural capital is affected by climate change, pollution, and commercial fisheries. Trophic level based indicators derived from fishery catch data may reveal the food web status of these systems, but the utility of these metrics has been debated because of targeting bias in fisheries catch. We analyze a unique, fishery-independent data set of North Pacific seabird tissues to inform ecosystem trends over 13 decades (1890s to 2010s). Trophic position declined broadly in five of eight species sampled, indicating a long-term shift from higher-trophic level to lower-trophic level prey. No species increased their trophic position. Given species prey preferences, Bayesian diet reconstructions suggest a shift from fishes to squids, a result consistent with both catch reports and ecosystem models. Machine learning models further reveal that trophic position trends have a complex set of drivers including climate, commercial fisheries, and ecomorphology. Our results show that multiple species of fish-consuming seabirds may track the complex changes occurring in marine ecosystems.

AB - Atmospheric carbon dioxide (CO2) data for the last 420 million years (My) show long-term fluctuations related to supercontinent cycles as well as shorter cycles at 26 to 32 My whose origin is unknown. Periodicities of 26 to 30 My occur in diverse geological phenomena including mass extinctions, flood basalt volcanism, ocean anoxic events, deposition of massive evaporites, sequence boundaries, and orogenic events and have previously been linked to an extraterrestrial mechanism. The vast oceanic crustal carbon reservoir is an alternative potential driving force of climate fluctuations at these time scales, with hydrothermal crustal carbon uptake occurring mostly in young crust with a strong dependence on ocean bottom water temperature. We combine a global plate model and oceanic paleo-age grids with estimates of paleo-ocean bottom water temperatures to track the evolution of the oceanic crustal carbon reservoir over the past 230 My. We show that seafloor spreading rates as well as the storage, subduction, and emission of oceanic crustal and mantle CO2 fluctuate with a period of 26 My. A connection with seafloor spreading rates and equivalent cycles in subduction zone rollback suggests that these periodicities are driven by the dynamics of subduction zone migration. The oceanic crust-mantle carbon cycle is thus a previously overlooked mechanism that connects plate tectonic pulsing with fluctuations in atmospheric carbon and surface environments.

AB - Upwards of 90% of individuals with Bardet-Biedl syndrome (BBS) display rod-cone dystrophy with early macular involvement. BBS is an autosomal recessive, genetically heterogeneous, pleiotropic ciliopathy for which 21 causative genes have been discovered to date. In addition to retinal degeneration, the cardinal features of BBS include obesity, cognitive impairment, renal anomalies, polydactyly, and hypogonadism. Here, we review the genes, proteins, and protein complexes involved in BBS and the BBS model organisms available for the study of retinal degeneration. We include comprehensive lists for all known BBS genes, their known phenotypes, and the model organisms available. We also review the molecular mechanisms believed to lead to retinal degeneration. We provide an overview of the mode of inheritance and describe the relationships between BBS genes and Joubert syndrome, Leber Congenital Amaurosis, Senior-Loken syndrome, and non-syndromic retinitis pigmentosa. Finally, we propose ways that new advances in technology will allow us to better understand the role of different BBS genes in retinal formation and function. PMID- 29457136 TI - Unexpected evolutionary benefit to phages imparted by bacterial CRISPR-Cas9. AB - Bacteria and bacteriophages arm themselves with various defensive and counterdefensive mechanisms to protect their own genome and degrade the other's. CRISPR (clustered regularly interspaced short palindromic repeat)-Cas (CRISPR associated) is an adaptive bacterial defense mechanism that recognizes short stretches of invading phage genome and destroys it by nuclease attack. Unexpectedly, we discovered that the CRISPR-Cas system might also accelerate phage evolution. When Escherichia coli bacteria containing CRISPR-Cas9 were infected with phage T4, its cytosine hydroxymethylated and glucosylated genome was cleaved poorly by Cas9 nuclease, but the continuing CRISPR-Cas9 pressure led to rapid evolution of mutants that accumulated even by the time a single plaque was formed. The mutation frequencies are, remarkably, approximately six orders of magnitude higher than the spontaneous mutation frequency in the absence of CRISPR pressure. Our findings lead to the hypothesis that the CRISPR-Cas might be a double-edged sword, providing survival advantages to both bacteria and phages, leading to their coevolution and abundance on Earth.

AB - Small airways disease (SAD) is one of the leading causes of airflow limitations in patients diagnosed with chronic obstructive pulmonary disease (COPD). Parametric response mapping (PRM) of computed tomography (CT) scans allows for the quantification of this previously invisible COPD component. Although PRM is being investigated as a diagnostic tool for COPD, variability in the longitudinal measurements of SAD by PRM has been reported. Here, we show a method for correcting longitudinal PRM data because of non-pathological variations in serial CT scans. In this study, serial whole-lung high-resolution CT scans over a 30-day interval were obtained from 90 subjects with and without COPD accrued as part of SPIROMICS. It was assumed in all subjects that the COPD did not progress between examinations. CT scans were acquired at inspiration and expiration, spatially aligned to a single geometric frame, and analyzed using PRM. By modeling variability in longitudinal CT scans, our method could identify, at the voxel level, shifts in PRM classification over the 30-day interval. In the absence of any correction, PRM generated serial percent volumes of functional SAD with differences as high as 15%. Applying the correction strategy significantly mitigated this effect with differences ~1%. At the voxel-level, significant differences were found between baseline PRM classifications and the follow-up map computed with and without correction (P <. 01 over GOLD). This strategy of accounting for nonpathological sources of variability in longitudinal PRM may improve the quantification of COPD phenotypes transitioning with disease progression.

AB - To fully achieve the goals of a genomics-enabled learning health care system, purposeful efforts to understand and reduce health disparities and improve equity of care are essential. This paper highlights three major challenges facing genomics-enabled learning health care systems, as they pertain to ancestrally diverse populations: inequality in the utility of genomic medicine; lack of access to pharmacogenomics in clinical care; and inadequate incorporation of social and environmental data into the electronic health care record (EHR). We advance a framework that can not only be used to directly improve care for all within the learning health system, but can also be used to focus on the needs to address racial and ethnic health disparities and improve health equity. PMID- 29457139 TI - Enhanced n-Doping Efficiency of a Naphthalenediimide-Based Copolymer through Polar Side Chains for Organic Thermoelectrics. AB - N-doping of conjugated polymers either requires a high dopant fraction or yields a low electrical conductivity because of their poor compatibility with molecular dopants. We explore n-doping of the polar naphthalenediimide-bithiophene copolymer p(gNDI-gT2) that carries oligoethylene glycol-based side chains and show that the polymer displays superior miscibility with the benzimidazole dimethylbenzenamine-based n-dopant N-DMBI. The good compatibility of p(gNDI-gT2) and N-DMBI results in a relatively high doping efficiency of 13% for n-dopants, which leads to a high electrical conductivity of more than 10-1 S cm-1 for a dopant concentration of only 10 mol % when measured in an inert atmosphere. We find that the doped polymer is able to maintain its electrical conductivity for about 20 min when exposed to air and recovers rapidly when returned to a nitrogen atmosphere. Overall, solution coprocessing of p(gNDI-gT2) and N-DMBI results in a larger thermoelectric power factor of up to 0.4 MUW K-2 m-1 compared to other NDI based polymers.

PMID- 29457142 TI - Cross-country Association of Press Freedom and LGBT freedom with prevalence of persons living with HIV: implication for global strategy against HIV/AIDS. AB - Background: Human behaviors are affected by attitudes and beliefs, which in turn are shaped by higher-level values to which we have ascribed. In this study, we explore the relationship between two higher-level values, press freedom and LGBT freedom, and HIV infection with national data at the population level. Methods: Data were the number of persons living with HIV (PLWH, n = 35,468,911) for 148 countries during 2011-15, press freedom index (PFI) determined by the Reporters Without Borders, and LGBT freedom index (LGBT-FI) based on laws regulating same sex relationships and expression. PLWH prevalence (1/1000), PFI and LGBT-FI were mapped first. Multiple regression was thus used to associate the logarithm of PLWH prevalence with PFI, LGBT-FI and PFI * LGBT-FI interaction, controlling for per capita GDP and weighted by population size. Results: Global prevalence of PLWH during 2011-15 was 0.51 per 1000 population. The prevalence showed a geographic pattern moving from high at the south and west ends of the world map to low at the north and east. Both PFI and LGBT-FI were positively associated with PLWH prevalence with a negative interaction between the two. Conclusions: More people are infected with HIV in countries with higher press freedom and higher LGBT freedom. Furthermore, press freedom can attenuate the positive association between levels of LGBT freedom and risk of HIV infection. This study demonstrated the urgency for and provided data supporting further research to investigate potential cultural and socioecological mechanisms underpinning the complex relationship among press freedom, LGBT freedom and HIV infection, with data collected at the individual level. PMID- 29457143 TI - Reciprocity in ROS and autophagic signaling. AB - Reactive oxygen species (ROS) are important signaling molecules that mediate oxidative stress and cellular damage when improperly regulated. ROS and oxidative stress can activate autophagy, which generally serves as a cytoprotective negative feedback mechanism to selectively eliminate sources of ROS, including mitochondria and peroxisomes. In this review we describe the mechanisms by which ROS directly and indirectly activate autophagy, and conversely, how selective autophagy suppresses the formation of ROS. Furthermore, we highlight what appear to be contradictory examples in which ROS suppress, rather than activate, autophagy; and where selective autophagy promotes, rather than inhibits ROS production, thereby contributing to cell death. Given that ROS are implicated in cancer, diabetes, atherosclerosis, neurodegenerative diseases and ischemia/reperfusion injury, a deeper understanding of the connections linking ROS and autophagy is greatly needed. PMID- 29457141 TI - EXTRAHEPATIC TOXICITY OF ACETAMINOPHEN: CRITICAL EVALUATION OF THE EVIDENCE AND PROPOSED MECHANISMS. AB - Research on acetaminophen (APAP) toxicity over the last several decades has focused on the pathophysiology of liver injury, but increasing attention is being paid to other known and possible adverse effects. It has been known for decades that APAP causes acute kidney injury, but confusion exists regarding prevalence, and the mechanisms have not been well investigated. More recently, a number of experimental, clinical and epidemiological studies have reported evidence for pulmonary, endocrine, neurological and neurodevelopmental toxicity, but the quality of evidence from those studies varies. It is important to consider these data due to implications for regulation and clinical practice. Here, we review the evidence and proposed mechanisms for extrahepatic adverse effects of APAP and weigh weaknesses and strengths in the data. We consider results from clinical, epidemiological and experimental research. Our goal is to determine the strength of claims regarding extrahepatic toxicity of APAP and to identify areas of need for future research. It is especially important to view claims of developmental effects of antenatal APAP exposure with a critical eye because APAP is currently the only over-the-counter medication recommended for pregnant women to self-treat pain and fever.

AB - Functional Near-Infrared Spectroscopy (fNIRS) maps human brain function by measuring and imaging local changes in hemoglobin concentrations in the brain that arise from the modulation of cerebral blood flow and oxygen metabolism by neural activity. Since its advent over 20 years ago, researchers have exploited and continuously advanced the ability of near infrared light to penetrate through the scalp and skull in order to non-invasively monitor changes in cerebral hemoglobin concentrations that reflect brain activity. We review recent advances in signal processing and hardware that significantly improve the capabilities of fNIRS by reducing the impact of confounding signals to improve statistical robustness of the brain signals and by enhancing the density, spatial coverage, and wearability of measuring devices respectively. We then summarize the application areas that are experiencing rapid growth as fNIRS begins to enable routine functional brain imaging.

AB - This paper proposes a novel method of using the frequency-domain transfer function to investigate the property of an iterative algorithm for minimizing a quadratic objective function. This paper focuses on a two-dimensional (2D) tomography problem, which can be X-ray computed tomography (CT), positron emission tomography (PET), and single photon emission computed tomography (SPECT). Two questions regarding to the linear iterative Landweber algorithm are considered. The first question is whether stopping early is equivalent to getting a minimum-norm solution. The second question is whether the low frequency components always converge first. Our answers to these two questions are No. PMID- 29457146 TI - Periodontal Biology: Stem Cells, Bmp2 Gene, Transcriptional Enhancers, and Use of Sclerostin Antibody and Pth for Treatment of Periodontal Disease and Bone Loss. AB - The periodontium is a complex tissue with epithelial components and a complex set of mesodermal derived alveolar bone, cellular and a cellular cementum, and tendon like ligaments (PDL). The current evidence demonstrates that the major pool of periodontal stem cells is derived from a population of micro vascular associated aSMA-positive stem/progenitor (PSC) cells that by lineage tracing form all three major mesodermal derived components of the periodontium. With in vitro aSMA+ stem cells, transcriptome and chip- seq experiments, the gene network and enhancer maps were determined at several differentiation states of the PSC. Current work on the role of the Bmp2 gene in the periodontal stem cell differentiation demonstrated that this Wnt regulated gene, Bmp2, is necessary for differentiation to all three major mesodermal derived component of the periodontium. The mechanism and use of Sclerostin antibody as an activator of Wnt signaling and Bmp2 gene as a potential route to treat craniofacial bone loss is discussed. As well, the mechanism and use of Pth in the treatment of periodontal bone loss or other craniofacial bone loss is presented in this review. PMID- 29457147 TI - A Scoping Review of Health Outcomes Examined in Randomized Controlled Trials Using Guided Imagery. AB - Introduction: Guided imagery involves the controlled visualization of detailed mental images. This integrative health technique is used for healing, health maintenance, or the treatment of specific conditions. Guided imagery is an integral part of mindfulness meditation, hypnosis, and various relaxation exercises. However, evidence to support the widespread use and dissemination of guided imagery interventions has been lacking. The purposes of this scoping review were to document the scope of health outcomes and disease processes examined by guided imagery researchers and the journal outlets where this work has been published. Secondary purposes were to review the efficacy of guided imagery, risk of bias from studies published in selected integrative health journals, and gain feedback from clinicians in a practiced-based research network (PBRN) about potential barriers for use in clinical settings. Methods: Ten bibliographic databases were searched for randomized controlled trials (RCTs) published between 1960 and 2013 that included adult participants. Descriptive and analytic methods were employed to document the journal outlets, diseases, and health outcomes investigated. Results: 320 RCTs that included more than 17,979 adult participants were reviewed. The published studies appeared in 216 peer reviewed journals from diverse disciplines largely representing psychology, the sport sciences, rehabilitation, nursing, and medicine. Major outcomes observed were coping with pain, stroke recovery, anxiety, coping with stress, and sport skills. Practitioner feedback from the PBRN revealed some interest but skepticism and time constraints were discussed as barriers. Conclusions: Ongoing research and creative dissemination techniques are warranted. PMID- 29457148 TI - Platelets at the Vascular Interface.

PMID- 29457149 TI - Working Memory Training in Adolescents Decreases Laboratory Risk Taking in the Presence of Peers. AB - Adolescence is a period of heightened risk-taking relative to both adulthood and childhood, due in part to peers' increased influence on adolescent decision making. Because adolescents' choices have harmful consequences, there is great interest in specific interventions that might attenuate risk taking. We hypothesized that it might be possible to reduce adolescent risk taking through an intervention targeting the ability/tendency to engage cognitive control processes. While some studies of Working Memory Training (WMT) have indicated subsequent enhancement of adults' cognitive control abilities, potential impacts on adolescent cognitive control have not been explored. Accordingly, we tested whether four weeks of WMT (relative to Active Control Training, ACT) might increase performance on cognitive control measures and decrease risk-taking in adolescents. Adolescents receiving WMT, compared to those receiving ACT, exhibited some evidence of improved short-term memory performance following the 4 week training period. Improvements did not significantly transfer to performance on basic cognitive control measures. However, on two risk-taking tasks administered at post-training either with or without an anonymous peer audience, adolescents who received WMT evinced suppressed levels of risk taking when observed by peers, an effect not seen in ACT. Further work is needed to more fully characterize the potential of WMT interventions in stemming risk behavior within adolescent samples. PMID- 29457150 TI - The links between agriculture, Anopheles mosquitoes, and malaria risk in children younger than 5 years in the Democratic Republic of the Congo: a population-based, cross-sectional, spatial study. AB - Background: The relationship between agriculture, Anopheles mosquitoes, and malaria in Africa is not fully understood, but it is important for malaria control as countries consider expanding agricultural projects to address population growth and food demand. Therefore, we aimed to assess the effect of agriculture on Anopheles biting behaviour and malaria risk in children in rural areas of the Democratic Republic of the Congo (DR Congo). Methods: We did a population-based, cross-sectional, spatial study of rural children (<5 years) in the DR Congo. We used information about the presence of malaria parasites in each child, as determined by PCR analysis of dried-blood spots from the 2013-14 DR Congo Demographic and Health Survey (DHS). We also used data from the DHS, a longitudinal entomological study, and available land cover and climate data to evaluate the relationships between agriculture, Anopheles biting behaviour, and malaria prevalence. Satellite imagery was used to measure the percentage of agricultural land cover around DHS villages and Anopheles sites. Anopheles biting behaviour was assessed by Human Landing Catch. We used probit regression to assess the relationship between agriculture and the probability of malaria infection, as well as the relationship between agriculture and the probability that a mosquito was caught biting indoors. Findings: Between Aug 13, 2013, and Feb 13, 2014, a total of 9790 dried-blood spots were obtained from the DHS, of which 4612 participants were included in this study. Falciparum malaria infection prevalence in rural children was 38.7% (95% uncertainty interval [UI] 37.3-40.0). Increasing exposure to agriculture was associated with increasing malaria risk with a high posterior probability (estimate 0.07, 95% UI -0.04 to 0.17; posterior probability [estimate >0]=0.89), with the probability of malaria infection increased between 0.2% (95% UI -0.1 to 3.4) and 2.6% (-1.5 to 6.6) given a 15% increase in agricultural cover, depending on other risk factors. The models predicted that large increases in agricultural cover (from 0% to 75%) increase the probability of infection by as much as 13.1% (95% UI -7.3 to 28.9). Increased risk might be due to Anopheles gambiae sensu lato, whose probability of biting indoors increased between 11.3% (95% UI -15.3 to 25.6) and 19.7% (-12.1 to 35.9) with a 15% increase in agriculture. Interpretation: Malaria control programmes must consider the possibility of increased risk due to expanding agriculture. Governments considering initiating large-scale agricultural projects should therefore also consider accompanying additional malaria control measures.

PMID- 29457152 TI - Minimax Rate-optimal Estimation of KL Divergence between Discrete Distributions. AB - We refine the general methodology in [1] for the construction and analysis of essentially minimax estimators for a wide class of functionals of finite dimensional parameters, and elaborate on the case of discrete distributions with support size S comparable with the number of observations n. Specifically, we determine the "smooth" and "non-smooth" regimes based on the confidence set and the smoothness of the functional. In the "non-smooth" regime, we apply an unbiased estimator for a "suitable" polynomial approximation of the functional. In the "smooth" regime, we construct a bias corrected version of the Maximum Likelihood Estimator (MLE) based on Taylor expansion. We apply the general methodology to the problem of estimating the KL divergence between two discrete distributions from empirical data. We construct a minimax rate-optimal estimator which is adaptive in the sense that it does not require the knowledge of the support size nor the upper bound on the likelihood ratio. Moreover, the performance of the optimal estimator with n samples is essentially that of the MLE with n ln n samples, i.e., the effective sample size enlargement phenomenon holds. PMID- 29457153 TI - Sparse Multi-view Task-Centralized Learning for ASD Diagnosis. AB - It is challenging to derive early diagnosis from neuroimaging data for autism spectrum disorder (ASD). In this work, we propose a novel sparse multi-view task centralized (Sparse-MVTC) classification method for computer-assisted diagnosis of ASD. In particular, since ASD is known to be age- and sex-related, we partition all subjects into different groups of age/sex, each of which can be treated as a classification task to learn. Meanwhile, we extract multi-view features from functional magnetic resonance imaging to describe the brain connectivity of each subject. This formulates a multi-view multi-task sparse learning problem and it is solved by a novel Sparse-MVTC method. Specifically, we treat each task as a central task and other tasks as the auxiliary ones. We then consider the task-task and view-view relations between the central task and each auxiliary task. We can use this task-centralized strategy for a highly efficient solution. The comprehensive experiments on the ABIDE database demonstrate that our proposed Sparse-MVTC method can significantly outperform the existing classification methods in ASD diagnosis. PMID- 29457151 TI - The Impact of IgG transplacental transfer on early life immunity. AB - Pediatric vaccines have significantly reduced infectious disease-related infant mortality, but as protective immunity often require several infant vaccine doses; maternally-acquired antibodies are critical to protect infants during the first months of life. Consequently, immunization of pregnant women is an important strategy not only to protect mothers from infection, but also to provide immunity to young infants. Nevertheless, maternal immunization can also negatively impact early life immunity. In fact, maternal antibodies can interfere with the development of infant immune responses, though it is unclear if such interference is clinically significant. Moreover, the transplacental transfer of maternal immunoglobulin therapeutics can be harmful to the fetus. Thus, the risk/benefit of maternal immunization for both the mother and the fetus should be carefully weighed. In addition, it is critical to fully understand the mechanisms by which IgG is transferred across the placenta in order to develop optimal maternal and infant immunization strategies. PMID- 29457154 TI - Motion-Robust Spatially Constrained Parameter Estimation in Renal Diffusion Weighted MRI by 3D Motion Tracking and Correction of Sequential Slices. AB - In this work, we introduce a novel motion-robust spatially constrained parameter estimation (MOSCOPE) technique for kidney diffusion-weighted MRI. The proposed motion compensation technique does not require a navigator, trigger, or breath hold but only uses the intrinsic features of the acquired data to track and compensate for motion to reconstruct precise models of the renal diffusion signal. We have developed a technique for physiological motion tracking based on robust state estimation and sequential registration of diffusion sensitized slices acquired within 200ms. This allows a sampling rate of 5Hz for state estimation in motion tracking that is sufficiently faster than both respiratory and cardiac motion rates in children and adults, which range between 0.8 to 0.2Hz, and 2.5 to 1Hz, respectively. We then apply the estimated motion parameters to data from each slice and use motion-compensated data for 1) robust intra-voxel incoherent motion (IVIM) model estimation in the kidney using a spatially constrained model fitting approach, and 2) robust weighted least squares estimation of the diffusion tensor model. Experimental results, including precision of IVIM model parameters using bootstrap-sampling and in-vivo whole kidney tractography, showed significant improvement in precision and accuracy of these models using the proposed method compared to models based on the original data and volumetric registration. PMID- 29457155 TI - VIGAN: Missing View Imputation with Generative Adversarial Networks. AB - In an era when big data are becoming the norm, there is less concern with the quantity but more with the quality and completeness of the data. In many disciplines, data are collected from heterogeneous sources, resulting in multi view or multi-modal datasets. The missing data problem has been challenging to address in multi-view data analysis. Especially, when certain samples miss an entire view of data, it creates the missing view problem. Classic multiple imputations or matrix completion methods are hardly effective here when no information can be based on in the specific view to impute data for such samples. The commonly-used simple method of removing samples with a missing view can dramatically reduce sample size, thus diminishing the statistical power of a subsequent analysis. In this paper, we propose a novel approach for view imputation via generative adversarial networks (GANs), which we name by VIGAN. This approach first treats each view as a separate domain and identifies domain to-domain mappings via a GAN using randomly-sampled data from each view, and then employs a multi-modal denoising autoencoder (DAE) to reconstruct the missing view from the GAN outputs based on paired data across the views. Then, by optimizing the GAN and DAE jointly, our model enables the knowledge integration for domain mappings and view correspondences to effectively recover the missing view. Empirical results on benchmark datasets validate the VIGAN approach by comparing against the state of the art. The evaluation of VIGAN in a genetic study of substance use disorders further proves the effectiveness and usability of this approach in life science.

AB - PURPOSE: To investigate the effect of Ca(OH)2 concentration on pH neutralization, degree of conversion (DC%), and bonding performance of experimental self-etch adhesives (SEAs). MATERIALS AND METHODS: Four different concentrations of Ca(OH)2 (0 wt%, 1 wt%, 2 wt%, and 4 wt%) were added to the bond of an experimental two step SEA consisting of primer (10-MDP [30 wt%], TEG-DMA [30 wt%], ethanol [35 wt%], water [5 wt%], camphorquinone [0.5 wt%], and tertiary amine [0.5 wt%]) and bond (bis-GMA [50 wt%], TEG-DMA [30 wt%], HEMA [20 wt%], camphorquinone [0.5 wt%], and tertiary amine [0.5 wt%]) to form four groups: E0, E1, E2 and E4. pH neutralization was evaluated until it reached equilibrium, and DC% within the hybrid layer was analyzed by micro-Raman spectroscopy. Human molars were wet ground until the occlusal dentin was exposed, SEAs were applied, and composite buildups were constructed. After storage in distilled water at 37 degrees C for 24 h, the teeth were cut into composite-dentin beams. Microtensile bond strength (uTBS) was evaluated after 24 h of water storage at 37 degrees C. Nanoleakage was evaluated by SEM. Data were analyzed using ANOVA and Tukey's HSD test (a = 0.05). RESULTS: All the SEAs reached pH equilibrium after thirteen days, with E1 and E4 presenting the highest pH (p < 0.05). E0 and E1 presented lower DC% than did E2 and E4 (p < 0.05). All the SEAs showed statistically similar mTBS and nanoleakage (p > 0.05). CONCLUSION: The incorporation of Ca(OH)2 endowed the SEAs with pH neutralization ability and improved their DC%, without interfering with the bond strength to dentin or nanoleakage extent.

AB - PURPOSE: To determine the irradiance delivered by visible-light curing (VLC) units and obtain information about the exposure times and the maintenance protocols used by dentists. MATERIALS AND METHODS: The irradiance (mW/cm2) delivered by 526 VLCs from 302 dental offices from the Rhine-Main area, Germany, was measured using an integrating sphere (IS) and a MARC patient simulator (M PS); additional information was gathered using a survey. RESULTS: Irradiance was measured from 117 standard quartz-tungsten-halogen (QTH), 5 high-power QTH, 2 LED 1st-generation, 333 LED 2nd-generation, 61 LED 3rd-generation, and 8 plasma-arc curing (PAC) units. Depending on the measurement method, 8% (IS) or 11% (M-PS) of the VLCs delivered < 400 mW/cm2. Depending on the VLC, the shortest exposure times required to deliver a radiant exposure of 16 J/cm2 ranged from 7 to 294 s. The number of exposure cycles used by dentists when light curing a restoration ranged from 1 to 14. The shortest total exposure time used by dentists on a restoration was 5 s, the maximum was 200 s, and the median was 20 s. Of the 526 VLCs, 41% had intact, undamaged light tips. Only half of the dental offices checked the irradiance from their VLCs regularly, 97% disinfected the VLC, and 86% used eye protection. CONCLUSION: Approximately 10% of the VLCs delivered < 400 mW/cm2 and 14% of the dental offices used no form of eye protection. To achieve sufficient light curing of RBC restorations, more awareness about the VLCs used in the dental office is required.

AB - It has been observed that the properties of room temperature ionic liquids near solid substrates are different from those of bulk liquids, and these properties play an important role in the development of catalysts, lubricants, and electrochemical devices. In this paper, we report microscopic studies of ionic liquid/solid interfaces performed using molecular dynamics simulations. The structural and dynamic properties of 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide (BMIM-TFSI) on mica and graphite interfaces were thoroughly investigated to elucidate the microscopic origins of the formation of layered structures at the interfaces. Our investigation included the observation of structural and orientational changes of ions as a function of distance from the surfaces, and contour mappings of ions parallel and perpendicular to the surfaces. By virtue of such detailed analyses, we found that, during the 5 ns simulation, the closest layer of BMIM-TFSI behaves as a two dimensional ionic crystal on mica and as a liquid or liquid crystal on graphite.

AB - We show increased dynamic nuclear polarization by adding a low dosage of a S = 15/2 Gd based endohedral metallofullerene (EMF) to DNP samples. By adding 60 MUM Gd2@C79N, the nuclear polarization of 1H and 13C spins from 40 mM 4-oxo-TEMPO increases by approximately 40% and 50%, respectively, at 5 T and 1.2 K. Electron electron double resonance (ELDOR) measurements show that the high spin EMF shortens the electron relaxation times and increases electron spectral diffusion leading to the increased DNP enhancement.

AB - A novel single-step approach, named phase transformation interfacial growth (PTIG), was developed for the fabrication of metal-organic framework membranes on polymeric substrates.

AB - Energy-efficient electrochemical water splitting is one important way to produce hydrogen fuel but still faces many challenges. In this communication, we report that an amorphous Ni-P alloy shell electrodeposited on a CuO nanowire array supported on copper foam (CuO@Ni-P NA/CF) can be used for efficient water splitting in alkaline media. As a 3D catalytic electrode, it exhibits excellent activity both for the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER) with overpotentials of 106 mV for HER and 275 mV for OER to achieve a current density of 30 mA cm-2 in 1.0 M KOH. This bifunctional electrode enables a high-performance alkaline water electrolyzer to achieve a current density of 30 mA cm-2 at a cell voltage of 1.71 V. PMID- 29457162 TI - An efficient approach for enhancing the catalytic activity of Ni-MOF-74 via a relay catalyst system for the selective oxidation of benzylic C-H bonds under mild conditions. AB - Although nickel-based materials exhibit similar catalytic activity to palladium in organic synthesis, the selective oxidation of inert C-H bonds in the absence of other co-catalysts remains a largely unsolved challenge. This paper introduces a facile and efficient approach for enhancing the catalytic activity of Ni-MOF-74 with [bmim]Br via a relay catalysis strategy, which is excellent for the selective oxidation of benzylic C-H bonds. Notably, the catalyst recycling and scale up experiments demonstrated the practicability of the protocol. This method combines the catalytic advantages of MOFs and ionic liquids (ILs), and provides an insight into oxidation reactions by cheap and efficient Ni-based catalysts. PMID- 29457163 TI - Probing energy losses from dye desorption in cobalt complex-based dye-sensitized solar cells. AB - Self-assembly of organic sensitizer layers in cobalt complex-based DSCs was studied to elucidate its role in reducing the loss of charge recombination. DSCs with various dye loadings were fabricated by dye desorption without the aid of basic solvent. The FT-IR and UV results indicate the deprotonation of the anchoring organic sensitizers, which influences the conduction band of TiO2 remarkably by changing the surface potential. Positive band edge shifts and a decrease of the recombination rate constant are demonstrated to be the main factors affecting energy loss at open circuit. In contrast, absorbed photon conversion efficiency (APCE) analyses illuminate the crucial role of the packing of the anchoring sensitizer in reducing recombination loss at short circuit. This is further supported by numerical simulations, which show that APCE is primarily dependent on the recombination rate constant rather than the band edge shift at short circuit. These results highlight the importance of self-assembly of sensitizers with insulating groups in retarding charge recombination by forming overlapping molecular layers. PMID- 29457164 TI - Effect on absorption and electron transfer by using Cd(ii) or Cu(ii) complexes with phenanthroline as auxiliary electron acceptors (A) in D-A-pi-A motif sensitizers for dye-sensitized solar cells. AB - To broaden the absorption spectrum, improve intramolecular electronic push-pull balance capability, enhance electron transfer and promote the photovoltaic performances of dye sensitizers, four new polymeric metal complex dyes (PBDTT PhenCd, PBDTT-PhenCu, PPV-PhenCd and PPV-PhenCu) with donor-acceptor-pi-bridge acceptor (D-A-pi-A) structure were designed and synthesized. These dyes, for the first time, used the complexes of Cd(ii) or Cu(ii) with phenanthroline as auxiliary electron acceptors (A) instead of organic electron withdrawing groups and adopted thienylbenzo [1,2-b:4,5-b'] dithiophene (BDTT) or hydroquinone (PV) derivatives as electron donors (D) and 8-quinolinol derivatives as pi bridge and acceptors (A). The impacts of different auxiliary electron acceptors (A) of metal complexes due to their thermal, optical, electrochemical properties and photovoltaic performance were also investigated. The best power conversion efficiency of 6.68% was achieved in PBDTT-PhenCd DSSC device. In addition, all dyes showed outstanding thermal stability (Td > 300 degrees C). The results revealed that these novel polymeric metal complex dyes are potential materials for constructing new sensitizers of high performance.

AB - Porous monolithic advanced functional materials based on supported ionic liquid like phase (SILLP) systems were used for the preparation of oleophilic and hydrophobic cylindrical membranes and successfully tested as eco-friendly and safe systems for oil/water separation and for the continuous integration of catalytic and separation processes in an aqueous-organic biphasic reaction system. PMID- 29457166 TI - A vibrational circular dichroism (VCD) methodology for the measurement of enantiomeric excess in chiral compounds in the solid phase and for the complementary use of NMR and VCD techniques in solution: the camphor case. AB - For the first time, the success of a methodology for the determination of enantiomeric excess (% ee) in chiral solid samples by vibrational circular dichroism (VCD) spectroscopy is reported. We have used camphor to determine the % ee in a blind sample constituted by a mixture of its two enantiomers as a test for the validity of our approach. IR and VCD spectra of different enantiomeric mixtures of R/S-camphor in Nujol mulls were recorded and linear regressions of VCD intensities (DeltaAbs.) vs. % ee for selected bands were found. Finally, the VCD intensities of a blind sample were interpolated in these linear regressions, obtaining its % ee with a rms of 2.4. These results in the solid phase were complemented with the determination of % ee in the liquid phase by VCD and NMR techniques, which are proved to be complementary techniques to carry out this kind of analysis. In the same way as in the VCD solid phase, linear regressions of DeltaAbs. vs. % ee for selected bands were established, obtaining a rms of 1.1 in the % ee determination of a blind sample. 1H NMR experiments at 600 MHz using the chiral solvating agent, (S,S)-ABTE, allow the determination of the proportions of enantiomers in CD2Cl2 solution with great accuracy. 13C CPMAS NMR spectra prove that this technique cannot be used for conglomerates and/or solid solutions.

AB - We develop a new fluorescence method for the sensitive detection of alkaline phosphatase (ALP) based on dephosphorylation-initiated transcription reaction mediated dual signal amplification. This research demonstrates for the first time a significant improvement in ALP assay performance by using a nucleic acid amplification strategy, which enables sensitive detection of ALP activity in vitro and in cell extracts. Importantly, this method can be further applied for kinetic analysis and ALP inhibition assay. PMID- 29457171 TI - Exploiting coordination geometry to selectively predict the sigma-donor and pi acceptor abilities of ligands: a back-and-forth journey between electronic properties and spectroscopy. AB - Through an analysis of eighty tetrahedral and square-planar metal carbonyls of general formula [M(CO)(L')(L)2] including newly synthesized chlorocarbonyl rhodium complexes with chelating atropoisomeric diphosphanes, we show how coordination geometry can switch the carbonyl stretching frequency into a selective probe of the sigma-donor and pi-acceptor abilities of the ligands. We thus provide a framework whereby the sigma-donation and pi-backdonation constituents of the Dewar-Chatt-Duncanson model can be quantitatively predicted through spectroscopic data on coordinated CO moieties and vice versa. PMID- 29457172 TI - Inorganic mixed phase templated by a fatty acid monolayer at the air-water interface: the Mn and Mg case. AB - We studied by means of Grazing Incidence X-ray Diffraction (GIXD) coupled with X ray fluorescence spectroscopy the structure of a behenic acid monolayer spread at the surface of Mg2+/Mn2+ mixed aqueous solutions. For the pure Mg2+ and Mn2+ aqueous solutions, the cations induce at the surface different 2D lattice superstructures of the organic monolayer. These superstructures correspond to an inorganic organized monolayer anchored to the hydrophilic group of the ordered behenic acid monolayer. Among the various diffraction peaks, we focused on those characteristics of the behenic acid oblique cell. As the Mg2+ mole fraction x increases in the Mg2+/Mn2+ mixed subphase, a continuous evolution of the oblique cell parameters is observed indicating the insertion of Mg2+ cations in the Mn2+ ordered monolayer. Then, a further increase leads to the appearance of a coexistence between two oblique surface phases. The cell parameters of both phases evolve continuously along the x range of the transition until a single Mg rich ordered phase is detected. However, although the intensities of the peaks in the coexistence region are in agreement with a first-order phase transition, the cell parameters evolve simultaneously. Considering a thermodynamics analysis, this evidences that, apart from the concentration, another unidentified intensive parameter is varying. We suggest that it is the ionic strength, which appears to be strongly related to the concentrations. PMID- 29457173 TI - Aqueous TMAO solutions as seen by theoretical THz spectroscopy: hydrophilic versus hydrophobic water. AB - Solvation of trimethylamine-N-oxide (TMAO) by water is of great fundamental interest because this small molecule has both strongly hydrophilic and large hydrophobic groups at its opposite ends and, furthermore, stabilizes proteins against temperature and pressure denaturation. Since hydrophilic and hydrophobic groups affect the structural dynamics of the respective solvation water molecules in vastly different ways, we dissect their distinct influences on the THz spectrum of TMAO(aq) by using ab initio molecular dynamics simulations. In particular, we demonstrate that exclusively electronic polarization and charge transfer effects, being absent in the usual fixed-charge biomolecular force fields, are responsible for the significant enhancement of the effective molecular dipole moment of hydrophilic solvation water. This, in turn, leads to pronounced solute-solvent couplings and thus to specific THz modes that involve well-defined H-bond bending and stretching motion being characteristic to hydrophilic solvation. The THz response of individual H-bonded pairs of water molecules involving hydrophobic solvation water, in stark contrast, is nearly indistinguishable from such pairs in bulk water. Transcending the specific case, THz spectroscopy is suggested to be an ideal experimental approach to unravel the controversial piezolytic properties of TMAO including its counteracting effect on pressure-induced denaturation of proteins.

AB - Using real time small-angle X-ray scattering, we ellucidate a hitherto unobserved non-monotonic evolution of inter-particle correlation while colloidal particles assemble across pore boundary in a confined medium under influence of solvent evaporation. Time variation of local volume fraction of the particles passes through distinct modulation prior to reaching equilibrium. It has been demonstrated that the amplitude of oscillation depends strongly on size of the assembling particles. We comprehend such non-linear temporal evolution of particle correlation through density functional theory and molecular dynamics simulation.

AB - Open-shell pi-conjugated compounds have recently received intense attention due to their unique properties and promising applications in materials science. However, the experiments on how the substituents affect their chemical bonding and structural motif remain less addressed. In this work, a series of tetrabenzo Chichibabin's hydrocarbon (TBC) derivatives substituted by different electron donating or -withdrawing groups at the termini were synthesized. The substituent effect was studied via X-ray crystallographic analysis. The strong electron donating dimethylamino-group substituted TBC derivative underwent simultaneous oxidation to give two cyanine-like moieties at the termini. More interestingly, it exhibited unusual thermochromic and thermomagnetic behaviours. PMID- 29457176 TI - Effect of HU protein on the conformation and compaction of DNA in a nanochannel. AB - The effect of the heat unstable nucleoid structuring protein HU on the conformation of single DNA molecules confined in a nanochannel was investigated with fluorescence microscopy. Pre-incubated DNA molecules contract in the longitudinal direction of the channel with increasing concentration of HU. This contraction is mainly due to HU-mediated bridging of distal DNA segments and is controlled by channel diameter as well as ionic composition and strength of the buffer. For over-threshold concentrations of HU, the DNA molecules compact into an condensed form. Divalent magnesium ions facilitate, but are not required for bridging nor condensation. The conformational response following exposure to HU was investigated with a nanofluidic device that allows an in situ change in environmental solution conditions. The stretch of the nucleoprotein complex first increases, reaches an apex in ~20 min, and subsequently decreases to an equilibrium value pertaining to pre-incubated DNA molecules after ~2 h. This observation is rationalised in terms of a time-dependent bending rigidity by structural rearrangement of bound HU protein followed by compaction through bridging interaction. Results are discussed in regard to previous results obtained for nucleoid associated proteins H-NS and Hfq, with important implications for protein binding related gene regulation.

The nature of formed bilayer architectures is governed by the functionalization of alkyl chains of SAILs via an amide or ester moiety. PMID- 29457179 TI - An experimental and theoretical investigation of XPS and NEXAFS of 5-halouracils. AB - The C, N and O 1s excitation and ionization processes of 5X-uracil (X = F, Cl, Br, and I) were investigated using near edge X-ray absorption fine structure (NEXAFS) and X-ray photoemission (XPS) spectroscopies. This study aims at the fine assessment of the effects of the functionalization of uracil molecules by halogen atoms having different electronegativity and bound to the same molecular site. Two DFT-based approaches, which rely on different paradigms, have been used to simulate the experimental spectra and to assign the corresponding features. The analysis of the screening of the core holes of the different atoms via electronic charge density plots has turned out to be a useful tool to illustrate the competition between the partially aromatic and partially conjugate properties of this class of molecules. PMID- 29457180 TI - Multiscale design of ZnO nanostructured photocatalysts. AB - A systematic investigation of the photocatalytic activity (PCA) of nanostructured ZnO films showed how this is directly affected by the films' morphology at different scales, from the macroscale morphology of films (e.g. thickness and surface area), to the microscale feature arrangement (e.g. aligned vs. randomly oriented structures or interpenetrated ones), to the nanoscale structure (e.g. crystal size and orientation). The interest in immobilizing photocatalysts in water treatment stems from concerns about the potential toxicity of their slurry form, which requires expensive downstream removal. Immobilisation, though, leads to a reduction in PCA, generally attributed to a lower surface area. By reducing the films' feature size to the nanoscale, an immobilized photocatalyst with high surface area can be achieved. At this scale, however, feature structuring and morphology become important as they determine the interaction between light and the photocatalytic material. In this work, nanostructured ZnO films with different morphology, arrangement and structure were produced by electrochemical anodization of zinc and were tested using the degradation of phenol in a batch reactor as a model system. Results show that the PCA for immobilized catalysts can be optimised by controlling microscale arrangement (light absorbance capacity) and nanoscale structure (crystal size and orientation) rather than macroscale morphology (surface area). These results provide a clear direction to maximising the photocatalytic activity of immobilised photocatalysts for the removal of organic pollutants from water. PMID- 29457181 TI - Ab initio kinetics of the HOSO2 + 3O2 -> SO3 + HO2 reaction. AB - The detailed kinetic mechanism of the HOSO2 + 3O2 reaction, which plays a pivotal role in the atmospheric oxidation of SO2, was investigated using accurate electronic structure calculations and novel statistical thermodynamic/kinetic models. Explored using the accurate composite method W1U, the detailed potential energy surface (PES) revealed that the addition of O2 to a HOSO2 radical to form the adduct (HOSO4) proceeds via a transition state with a slightly positive barrier (i.e., 0.7 kcal mol-1 at 0 K). Such a finding compromises a long-term hypothesis about this channel of being a barrierless process. Moreover, the overall reaction was found to be slightly exothermic by 1.7 kcal mol-1 at 0 K, which is in good agreement with recent studies. On the newly-constructed PES, the temperature- and pressure-dependent behaviors of the title reaction were characterized in a wide range of conditions (T = 200-1000 K & P = 10-760 Torr) using the integrated deterministic and stochastic master equation/Rice-Ramsperger Kassel-Marcus (ME/RRKM) rate model in which corrections for hindered internal rotation (HIR) and tunneling treatments were included. The calculated numbers were found to be in excellent agreement with literature data. The sensitivity analyses on the derived rate coefficients with respect to the ab initio input parameters (i.e., barrier height and energy transfer) were also performed to further understand the kinetic behaviors of the title reaction. The detailed kinetic mechanism, consisting of thermodynamic and kinetic data (in NASA polynomial and modified Arrhenius formats, respectively), was also provided at different T & P for further use in the modeling/simulation of any related systems.

PMID- 29457183 TI - Diabatic potential energy surfaces of MgH2+ and dynamic studies for the Mg+(3p) + H2 -> MgH+ + H reaction. AB - The global diabatic potential energy surfaces (PESs) of the MgH2+ system, which can be used to study the dynamics of the Mg+(3p2P) + H2(X1Sigma) -> MgH+(X1Sigma+) + H(2S) reaction, are structured for the first time. The diabatic PESs are correlated with the ground state 12A' and the first excited state 22A'. The multi-reference configuration interaction method and the VQZ basis set are used in ab initio calculations, and diabatic potential energies are calculated based on the molecular properties of the dipole moment. The neural network method is applied to fit the matrix elements of the diabatic energy surfaces. Spectroscopic constants of H2(X1Sigmag+) and MgH+(X1Sigma+) obtained from the new PESs agree well with the experimental data. Based on the diabatic PESs of MgH2+, the time-dependent wavepacket calculations for the Mg+(3p2P) + H2(X1Sigmag+) -> MgH+(X1Sigma+) + H(2S) reaction are carried out to study the reaction dynamics. There is no threshold for this reaction because of the existence of barrierless reactive paths. The reaction has a high total integral cross section (ICS), and vibrationally resolved ICSs show an obvious population inversion of product vibrational states. The results of differential cross sections (DCSs) indicate that most product molecules tend to forward scatter. PMID- 29457185 TI - Effect of large deformation and surface stiffening on the transmission of a line load on a neo-Hookean half space. AB - A line force acting on a soft elastic solid, say due to the surface tension of a liquid drop, can cause significant deformation and the formation of a kink close to the point of force application. Analysis based on linearized elasticity theory shows that sufficiently close to its point of application, the force is borne entirely by the surface stress, not by the elasticity of the substrate; this local balance of three forces is called Neumann's triangle. However, it is not difficult to imagine realistic properties for which this force balance cannot be satisfied. For example, if the line force corresponds to surface tension of water, the numerical values of (unstretched) solid-vapor and solid-liquid surface stresses can easily be such that their sum is insufficient to balance the applied force. In such cases conventional (or naive) Neumann's triangle of surface forces must break down. Here we study how force balance is rescued from the breakdown of naive Neumann's triangle by a combination of (a) large hyperelastic deformations of the underlying bulk solid, and (b) increase in surface stress due to surface elasticity (surface stiffening). For a surface with constant surface stress (no surface stiffening), we show that the linearized theory remains accurate if the applied force is less than about 1.3 times the solid surface stress. For a surface in which the surface stress increases linearly with the surface stretch, we find that the Neumann's triangle construction works well as long as we replace the constant surface stress in the naive Neumann triangle by the actual surface stress underneath the line load.

AB - The control of reaction pathways for selective and enantiospecific synthesis of functionalized pyrrolidines and gamma-amino ketones has been realized. Rhodium catalyzed [3+2] cycloadditions of vinylaziridines and enolsilanes with a bulky silyl group gave functionalized pyrrolidines with moderate to excellent diastereoselectivities, while the reaction of silyl enol ethers with a less bulky silyl group afforded chiral gamma-amino ketones in good yields. PMID- 29457189 TI - Development of a Questionnaire to Assess Nursing Competencies for the Care of People with Psychiatric Disabilities in a Hospital Environment. AB - The recovery of people with psychiatric disabilities requires high-quality nursing care. However, the existing research on the nursing competencies needed for caring for people with psychiatric disabilities have been based on a narrow competency framework. By adopting a broader competency framework, this study aimed to find the competencies needed for the nursing care of people with psychiatric disabilities in a hospital environment. Accordingly, a questionnaire will be developed to measure these competences. First, a literature review and interviews with psychiatrists, psychiatric nurses, and people with psychiatric disabilities were conducted to develop the pool of competency items. Second, a pilot study was conducted to review the initial pool of items. Finally, a survey of 581 psychiatric nurses was used to conduct a series of principal component analyses to explore the structure of the questionnaire. The 17-item questionnaire included 5 factors, which accounted for 68.60% of the total variance: sense of responsibility, vocational identification, agreeableness, cooperation capacity, and carefulness; the Cronbach's alpha coefficients were 0.85, 0.85, 0.74, 0.80, and 0.77, respectively. Most of the competencies belonged to attitudes, values, and traits, which were overlooked in previous studies. The questionnaire has satisfactory internal reliability and structural validity, and could contribute some to the selection of the psychiatric workforce. PMID- 29457190 TI - Family-Based Interventions Targeting Improvements in Health and Family Outcomes of Children and Adolescents with Type 1 Diabetes: a Systematic Review. AB - PURPOSE OF REVIEW: A systematic review was conducted of family-based interventions to improve glycemic control, adherence, and psychosocial outcomes in children and adolescents with type 1 diabetes (T1D). Electronic databases were searched for randomized controlled trials (RCTs) published since the seminal Diabetes Control and Compliance Trial (DCCT). Interventions are summarized and findings reviewed to help guide clinical practice and future research. RECENT FINDINGS: Twenty-five RCTs are reviewed. The majority of studies (n = 15) focused on interventions targeting both children and adolescents and their caregivers and were delivered in diabetes clinics, outpatient settings, mental health clinics, or participants' homes. Family-based interventions for youth with T1D appear effective at improving diabetes and family-centered outcomes. Additional research is needed to examine the pathways to improvement in glycemic control, as outcomes were mixed. Future research should also involve measures beyond HbA1c given new markers for sustained health improvement and outcomes are being explored. PMID- 29457191 TI - Variation in intraocular pressure caused by repetitive positional changes during laparoscopic colorectal surgery: a prospective, randomized, controlled study comparing propofol and desflurane anesthesia. AB - Laparoscopic surgery is often prolonged and requires positional changes to facilitate surgical access. Previous studies reported intraocular pressure (IOP) changes in one fixed position. This study investigated the effect of desflurane and propofol anesthesia on IOP during repeated positional changes. A total of 46 patients undergoing laparoscopic colorectal surgery were randomized into desflurane or propofol groups. IOP was measured using a handheld tonometer at seven time points: before induction (baseline), after endotracheal intubation, after pneumoperitoneum, after the first Trendelenburg and right tilt position, after reverse Trendelenburg and right tilt position, after the second Trendelenburg and right tilt position and before endotracheal extubation. Trendelenburg positioning raised IOP in both groups. In the desflurane group, IOP at the first Trendelenburg position was 6.27 and 8.48 mmHg higher than baseline IOP in left and right eye, respectively; IOP at the second Trendelenburg position was 7 and 9.44 mmHg higher than baseline in left and right eye, respectively. In the propofol group, IOP at the first Trendelenburg position was 2.04 and 4.04 mmHg higher than baseline in left and right eyes, respectively. It was 3.04 and 4.87 mmHg higher than baseline in left and right eye, respectively, at the second Trendelenburg position. In the desflurane group, 56.52% patients exhibited high IOP (>= 25 mmHg) compared with 13.04% in the propofol group at the second Trendelenburg position in the right eyes (P = 0.005). There was a positive correlation between IOP and peak inspiratory pressure (P < 0.001). Propofol anesthesia mitigated wide variations in IOP caused by repetitive positional changes during laparoscopic colorectal surgery.

AB - BACKGROUND: Magnetic resonance imaging (MRI) has been used to study configurations of speech organs in the resting state. However, MRI is sensitive to metals, and numerous types of metallic appliances, most of which have a large magnetic susceptibility, are used in orthodontic treatment and may cause severe artifacts on MRI. We have developed techniques for obtaining MRI movies of the oral region, to evaluate articulatory changes, especially movement of the tongue, palate, and teeth, pre- and post-orthodontic/orthognathic treatment. We evaluated the influence of artifacts caused by orthodontic appliances, including fixed retainers, metal brackets, and wires, on measurements in 3-T MRI movies. METHODS: Sixteen healthy young adults (nine males, seven females; average age, 27 years) with normal occlusion were recruited. Four types of customized maxillary and mandibular plates were prepared by incorporating one of the following into the plate: (a) nothing, (b) a fixed canine-to-canine retainer, (c) metal brackets for the anterior and molar teeth, or (d) clear brackets for the anterior teeth and metal brackets for molars. A 3-T MRI movie, in segmented cine mode, was generated for each plate condition while participants pronounced a vowel-consonant-vowel syllable (/asa/). The size of the artifact due to the metallic brackets was measured. The face size and orthodontically important anatomical structures, such as the velum, the hard palate, and the laryngeal ventricle, were also measured. RESULTS: A large artifact was observed over the entire oral region around orthodontic appliances, altering regional visibility. The velopharyngeal height was measured as significantly longer in the presence of metal brackets. The maximum artifact size due to a metallic bracket was > 8 cm. Our results show that even if it is possible to obtain the measurements of palate length, nasion to sella, and nasion to basion in individuals wearing metal brackets for molars, the measurements might be affected due to the presence of artifacts. CONCLUSIONS: Orthodontic appliances, including metallic materials, sometimes produce significant measurement error in speech evaluation using MRI movies, which often become invisible or distorted by metallic orthodontic appliances. When the distorted image is measured, caution should be exercised, as the measurement may be affected. Based on the study, it is concluded that orthodontists should not necessarily remove all metallic appliances before MRI examination because the influence varies among the appliances and should also know that a significant measurement error in speech evaluation using MRI movie may occur by image distortion caused by metallic artifacts.

AB - The production of virginiamycin (VGM) from Streptomyces virginiae was improved by genome shuffling and ribosome engineering companied with a high-throughput screening method integrating deep-well cultivation and the cylinder-plate detecting. First, a novel high-throughput method was developed to rapidly screen large numbers of VGM-producing mutants. Then, the starting population of genome shuffling was obtained through ultraviolet (UV) and microwave mutagenesis, and four mutants with higher productivity of VGM were selected for genome shuffling. Next, the parent protoplasts were inactivated by UV and heat when a fusant probability was about 98%. Streptomycin resistance was used as an evolutionary pressure to extend positive effects on VGM synthesis. Finally, after five rounds of genome shuffling, a genetically stable strain G5-103 was obtained and characterized to be able to yield 251 mg/L VGM, which was 3.1- and 11.6-fold higher than that of the mutant strain UV 1150 and the wild-type strain, respectively. PMID- 29457194 TI - Reproduction in woody perennial Citrus: an update on nucellar embryony and self incompatibility. AB - KEY MESSAGE: Review on citrus reproduction. Citrus is one of the most important and widely grown fruit crops. It possesses several special reproductive characteristics, such as nucellar embryony and self-incompatibility. The special phenomenon of nucellar embryony in citrus, also known as the polyembryony, is a kind of sporophytic apomixis. During the past decade, the emergence of novel technologies and the construction of multiple citrus reference genomes have facilitated rapid advances to our understanding of nucellar embryony. Indeed, several research teams have preliminarily determined the genetic basis of citrus apomixis. On the other hand, the phenomenon of self-incompatibility that promotes genetic diversity by rejecting self-pollen and accepting non-self-pollen is difficult to study in citrus because the long juvenile period of citrus presents challenges to identifying candidate genes that control this phenomenon. In this review, we focus on advances to our understanding of reproduction in citrus from the last decade and discuss priorities for the coming decade. PMID- 29457195 TI - The association between mood state and chronobiological characteristics in bipolar I disorder: a naturalistic, variable cluster analysis-based study. AB - BACKGROUND: Multiple types of chronobiological disturbances have been reported in bipolar disorder, including characteristics associated with general activity levels, sleep, and rhythmicity. Previous studies have focused on examining the individual relationships between affective state and chronobiological characteristics. The aim of this study was to conduct a variable cluster analysis in order to ascertain how mood states are associated with chronobiological traits in bipolar I disorder (BDI). We hypothesized that manic symptomatology would be associated with disturbances of rhythm. RESULTS: Variable cluster analysis identified five chronobiological clusters in 105 BDI subjects. Cluster 1, comprising subjective sleep quality was associated with both mania and depression. Cluster 2, which comprised variables describing the degree of rhythmicity, was associated with mania. Significant associations between mood state and cluster analysis-identified chronobiological variables were noted. Disturbances of mood were associated with subjectively assessed sleep disturbances as opposed to objectively determined, actigraphy-based sleep variables. No associations with general activity variables were noted. Relationships between gender and medication classes in use and cluster analysis identified chronobiological characteristics were noted. Exploratory analyses noted that medication class had a larger impact on these relationships than the number of psychiatric medications in use. CONCLUSIONS: In a BDI sample, variable cluster analysis was able to group related chronobiological variables. The results support our primary hypothesis that mood state, particularly mania, is associated with chronobiological disturbances. Further research is required in order to define these relationships and to determine the directionality of the associations between mood state and chronobiological characteristics. PMID- 29457196 TI - The Landscape of Diabetic Kidney Disease in the United States. AB - PURPOSE OF REVIEW: The purposes of this review are to identify population characteristics of important risk factors for the development and progression of diabetic kidney disease (DKD) in the United States and to discuss barriers and opportunities to improve awareness, management, and outcomes in patients with DKD. RECENT FINDINGS: The major risk factors for the development and progression of DKD include hyperglycemia, hypertension, and albuminuria. DKD disproportionately affects minorities and individuals with low educational and socioeconomic status. Barriers to effective management of DKD include the following: (a) limited patient and healthcare provider awareness of DKD, (b) lack of timely referrals of patients to a nephrologist, (c) low patient healthcare literacy, and (d) insufficient access to healthcare and health insurance. Increased patient and physician awareness of DKD has been shown to enhance patient outcomes. Multifactorial and multidisciplinary interventions targeting multiple risk factors and patient/physician education may provide better outcomes in patients with DKD. PMID- 29457197 TI - Inactivation of the indole-diterpene biosynthetic gene cluster of Claviceps paspali by Agrobacterium-mediated gene replacement. AB - The hypocrealean fungus Claviceps paspali is a parasite of wild grasses. This fungus is widely utilized in the pharmaceutical industry for the manufacture of ergot alkaloids, but also produces tremorgenic and neurotoxic indole-diterpene (IDT) secondary metabolites such as paspalitrems A and B. IDTs cause significant losses in agriculture and represent health hazards that threaten food security. Conversely, IDTs may also be utilized as lead compounds for pharmaceutical drug discovery. Current protoplast-mediated transformation protocols of C. paspali are inadequate as they suffer from inefficiencies in protoplast regeneration, a low frequency of DNA integration, and a low mitotic stability of the nascent transformants. We adapted and optimized Agrobacterium tumefaciens-mediated transformation (ATMT) for C. paspali and validated this method with the straightforward creation of a mutant strain of this fungus featuring a targeted replacement of key genes in the putative IDT biosynthetic gene cluster. Complete abrogation of IDT production in isolates of the mutant strain proved the predicted involvement of the target genes in the biosynthesis of IDTs. The mutant isolates continued to produce ergot alkaloids undisturbed, indicating that equivalent mutants generated in industrial ergot producers may have a better safety profile as they are devoid of IDT-type mycotoxins. Meanwhile, ATMT optimized for Claviceps spp. may open the door for the facile genetic engineering of these industrially and ecologically important organisms. PMID- 29457199 TI - The genetic self.

AB - As the advanced functional materials, silver nanoparticles are potentially useful in various fields such as photoelectric, bio-sensing, catalysis, antibacterial and other fields, which are mainly based on their various properties. However, the properties of silver nanoparticles are usually determined by their size, shape, and surrounding medium, which can be modulated by various synthesis methods. In this review, the fabrication methods for synthesizing silver nanoparticles of different shapes and specific size are illustrated in detail. Besides, the corresponding properties and applications of silver nanoparticles are also discussed in this paper. PMID- 29457201 TI - Validity of oral fluid test for Delta-9-tetrahydrocannabinol in drivers using the 2013 National Roadside Survey Data. AB - BACKGROUND: Driving under the influence of marijuana is a serious traffic safety concern in the United States. Delta 9-tetrahydrocannabinol (THC) is the main active compound in marijuana. Although blood THC testing is a more accurate measure of THC-induced impairment, measuring THC in oral fluid is a less intrusive and less costly method of testing. METHODS: We examined whether the oral fluid THC test can be used as a valid alternative to the blood THC test using a sensitivity and specificity analysis and a logistic regression, and estimate the quantitative relationship between oral fluid THC concentration and blood THC concentration using a correlation analysis and a linear regression on the log-transformed THC concentrations. We used data from 4596 drivers who participated in the 2013 National Roadside Survey of Alcohol and Drug Use by Drivers and for whom THC testing results from both oral fluid and whole blood samples were available. RESULTS: Overall, 8.9% and 9.4% of the participants tested positive for THC in oral fluid and whole blood samples, respectively. Using blood test as the reference criterion, oral fluid test for THC positivity showed a sensitivity of 79.4% (95% CI: 75.2%, 83.1%) and a specificity of 98.3% (95% CI: 97.9%, 98.7%). The log-transformed oral fluid THC concentration accounted for about 29% of the variation in the log-transformed blood THC concentration. That is, there is still 71% of the variation in the log transformed blood THC concentration unexplained by the log-transformed oral fluid THC concentration. Back-transforming to the original scale, we estimated that each 10% increase in the oral fluid THC concentration was associated with a 2.4% (95% CI: 2.1%, 2.8%) increase in the blood THC concentration. CONCLUSIONS: The oral fluid test is a highly valid method for detecting the presence of THC in the blood but cannot be used to accurately measure the blood THC concentration. PMID- 29457200 TI - Network-Based Research on Rural Opioid Use: an Overview of Methods and Lessons Learned. AB - PURPOSE OF REVIEW: The purpose of this paper is to provide a thorough overview of methods used for recruitment, network data collection, and network data management in a network-based study of rural people who use drugs (PWUD) and to offer methodological recommendations for future research on rural drug use. RECENT FINDINGS: The Social Networks among Appalachian People (SNAP) study recruited a cohort of 503 rural PWUD via respondent-driven sampling (RDS) and has retained more than 80% of eligible participants over 7-9 years. SNAP has yielded important methodological insights, including that (1) RDS referral was non-random and disproportionately involved kin and (2) interviewer-administered questionnaires were successful in eliciting accurate name and age information about network members. The SNAP experience suggests that RDS was a successful recruitment strategy for rural PWUD and questionnaires administered by community based interviewers in the context of a Certificate of Confidentiality could elicit detailed data on PWUD risk networks. PMID- 29457202 TI - Three new coccidians (Cyclospora, Eimeria) from eastern moles, Scalopus aquaticus (Linnaeus) (Mammalia: Soricomorpha: Talpidae) from Arkansas, USA. AB - Three new species of coccidians (Apicomplexa: Eimeriidae) are described from eastern moles, Scalopus aquaticus (Linnaeus) from Arkansas. Oocysts of Cyclospora duszynskii n. sp. are subspheroidal with a smooth bi-layered wall, measure 11.4 * 10.0 um, and have a length/width (L/W) ratio of 1.1; both micropyle and oocyst residuum are absent, but a single polar granule is present. Sporocysts are ellipsoidal and measure 7.2 * 5.4 um, L/W 1.3; an indistinct Stieda body is present, but the sub-Stieda and para-Stieda bodies are absent and the sporocyst residuum is composed of medium to large granules of different sizes along the edge of the sporocyst. Oocysts of Cyclospora yatesi n. sp. are subspheroidal to ovoidal with an ornate outer wall, measure 17.0 * 15.2 um, L/W 1.1; both micropyle and oocyst residuum are absent, but a single polar granule is present. Sporocysts are ellipsoidal and measure 9.7 * 7.3 um, L/W 1.3; an indistinct Stieda body is present, but sub-Stieda and para-Stieda bodies are absent and the sporocyst residuum is composed of medium to large granules of different sizes along the edge of the sporocyst. Oocysts of Eimeria paulettefordae n. sp. are ovoidal to ellipsoidal with an ornate outer wall, measure 30.0 * 25.4 um, L/W 1.2; both micropyle and oocyst residuum are absent, but a single polar granule is present. Sporocysts are ellipsoidal and measure 12.6 * 9.2 um, L/W 1.4; a button like Stieda body is present, but sub-Stieda and para-Stieda bodies are absent and the sporocyst residuum is composed of medium to large granules of different sizes along the edge of the sporocyst. These are the first coccidians described from Arkansas populations of S. aquaticus. In addition, a summary is provided on the cyclosporans and eimerians from North American talpids. PMID- 29457203 TI - Challenges and Opportunities in Establishing and Maintaining Newborn Screening in a Rural Area of Andhra Pradesh - Task Force Study by Indian Council of Medical Research. AB - OBJECTIVE: The primary objective was to evaluate the feasibility of setting up newborn screening in rural areas in India. Secondary objective was to enhance the knowledge and awareness towards early detection of diseases by newborn screening, management of the affected baby and to impart genetic counseling. METHODS: Awareness programs were conducted at different mandals in the district for the medical practioners during the preparatory phase of the Task Force Project. Educative lectures and clinical meetings regarding the importance and relevance of newborn screening were held every 3 months initially and half yearly later. Families were counselled during antenatal check-ups. RESULTS: Good co-operation was obtained from medical doctors and their willingness to participate in sample collection from the hospitals. Families accepted screening after an initial period of resistance. The fact that screening of this kind will help their babies made a positive impact. Many families started promoting newborn screening to their friends and relations. Confirmation of diagnosis, treatment, and follow-up were satisfactory with almost negligible number of cases lost to follow-up. CONCLUSIONS: With proper planning and commitment on the part of health authorities, it is possible to implement newborn screening in rural areas in India as well. PMID- 29457204 TI - Prevention and Management of Childhood Obesity. AB - Childhood obesity has been recognized as a global pandemic. Preventive strategies have proven to be the most effective public health intervention in curbing this pandemic. A multi-component approach involving dietary modification and advocacy for a healthy lifestyle comprising of regular physical activity, minimizing screen time and behavioral interventions have been found beneficial in preventing obesity. A life-cycle approach has been recommended where preventive interventions go as far back as affecting maternal, fetal and early childhood nutrition and lifestyle. Family, school and community involvement is important for long term results, so is the involvement of government in developing policies that help create an environment and opportunities for healthy diet and physical activity. Management of childhood obesity is challenging. It involves following a structured weight reduction programme individualized for every child, along with adoption of a healthy diet and life style. Anti-obesity drugs have a limited role in childhood years and are not recommended in younger children. Bariatric surgery is reserved for morbidly obese older adolescents but its long term safety data is limited in this age group. PMID- 29457205 TI - Growth Hormone Therapy and Lipid Profile.

PMID- 29457208 TI - Children Deserve Smoke Free World. AB - Tobacco smoke, active or passive exposure was the major cause of preventable morbidity and mortality in the world during twentieth century and will continue to be the same in the twenty-first century also if the current trends continue. Both active and passive smoking are having significance in relation to child health. Exposure starts antenatally from placenta to the fetus and later phases through passive exposure to experimental and regular smoking and ultimately addiction and habitual smoking. Evidences are in favour of causal relationship with intrauterine growth restriction, sudden infant death syndrome, decreased pulmonary function, increased risk for respiratory tract infection, otitis media, wheeze, asthma, neurobehavioral disorders, cleft palate and triggering pathogenesis of fetal and childhood onset of adult diseases, especially pulmonary and cardio vascular diseases. All these facts stress the importance of behavioral changes in the population as well as stringent public health measures and legislation for ensuring smoke free work places, public places and households for children. M POWER- Package by WHO is a novel global initiative taking us closer to the target of achieving tobacco free environment for children in the near future. PMID- 29457209 TI - Agreement Between Integrated Management of Childhood Illness and Final Diagnosis in Acute Respiratory Tract Infections. AB - OBJECTIVE: To evaluate the agreement between integrated management of childhood illness (IMCI) and final diagnosis in patients presenting with cough at the second and third level health institutions. METHODS: This cross-sectional study included 373 children aged 2-60 mo who presented with cough at the pediatric emergency and outpatient clinics in the Department of Pediatrics. After clinical examination of children, body temperature, respiratory rate, saturation, presence or absence of the chest indrawing, rales, wheezing and laryngeal stridor were recorded. Cases were categorized according to IMCI algorithm regarding the severity using the color code, such as red (urgent treatment), yellow (treatment in the hospital), or green (treatment at home). Final diagnosis after physical examination, laboratory analysis and chest X-ray was compared with the IMCI algorithm. RESULTS: Study agreement between IMCI classification and final diagnosis was 74.3% with kappa value 0.55 (moderate agreement). Similar agreement values were detected in both the second and third level health institutions. Health condition and gender did not affect agreement value. Agreement were found to be high in patients <24 mo of age (K = 0.67), presence of fever and cough (K = 0.54), tachypnea (K = 0.93), chest indrawing (K = 1.00) and oxygen saturation of <94%(K = 0.90). CONCLUSIONS: Adding saturation level to the IMCI algorithmic diagnosis may increase agreement between IMCI classification and final diagnosis.

PMID- 29457210 TI - Hospital Cirrhosis Volume and Readmission in Patients with Cirrhosis in California. AB - BACKGROUND: Patients with cirrhosis are at high readmission risk. Using a large statewide database, we evaluated the effect of hospital cirrhosis-related patient volume on 30-day readmissions in patients with cirrhosis. METHODS: We conducted a retrospective study of the Healthcare Cost and Utilization Project State Inpatient Database for adult patients with cirrhosis, as defined by International Classification of Diseases, Ninth Revision (ICD-9) codes, hospitalized in California between 2009 and 2011. Multivariable logistic regression analysis was performed to evaluate the effect of hospital volume on 30-day readmissions. RESULTS: A total of 69,612 patients with cirrhosis were identified in 405 hospitals; 24,062 patients were discharged from the top 10% of hospitals (N = 41) by cirrhosis volume, and 45,550 patients in the bottom 90% (N = 364). Compared with higher-volume centers, lower-volume hospitals cared for patients with similar average Quan-Charlson-Deyo (QCD) comorbidity scores (6.54 vs. 6.68), similar proportion of hepatitis B and fatty liver disease, lower proportion of hepatitis C (34.8 vs. 41.5%) but greater proportion of alcoholic liver disease (53.1 vs. 47.4%). Multivariable logistic regression analysis demonstrated admission to a lower-volume hospital did not predict 30-day readmission (odds ratio [OR] 0.97, 95% confidence interval [CI] 0.92-1.01) after adjusting for sociodemographics, QCD score, cirrhosis severity, and hospital characteristics. Instead, liver transplant center status significantly decreased the risk of readmission (OR 0.87, 95% CI 0.80-0.94). Ascites, hepatic encephalopathy, hepatocellular carcinoma, higher QCD, and presence of alcoholic liver disease and hepatitis C were also independent predictors. CONCLUSIONS: Readmissions within 30 days were common among patients with cirrhosis hospitalized in California. While hospital cirrhosis volume did not predict 30-day readmissions, liver transplant center status was protective of readmissions. Medically complicated patients with cirrhosis at hospitals without liver transplant centers may benefit from additional support to prevent readmission. PMID- 29457211 TI - Acetarsol Suppositories: Effective Treatment for Refractory Proctitis in a Cohort of Patients with Inflammatory Bowel Disease. AB - BACKGROUND: Management of proctitis refractory to conventional therapies presents a common clinical problem. The use of acetarsol suppositories, which are derived from organic arsenic, was first described in 1965. Data concerning clinical efficacy and tolerability are very limited. AIM: To examine the efficacy of acetarsol suppositories for the treatment of refractory proctitis. METHODS: A retrospective analysis was performed on patients with inflammatory bowel disease treated with acetarsol suppositories between 2008 and 2014 at Addenbrooke's Hospital, Cambridge, United Kingdom. Clinical response was defined as resolution of symptoms back to baseline at the time of next clinic review. RESULTS: Thirty nine patients were prescribed acetarsol suppositories between March 2008 and July 2014 (29 patients with ulcerative colitis, nine with Crohn's disease, and one with indeterminate colitis). Thirty-eight were included for analysis. The standard dose of acetarsol was 250 mg twice daily per rectum for 4 weeks. Clinical response was observed in 26 patients (68%). Of the 11 patients who had endoscopic assessment before and after treatment, nine (82%) showed endoscopic improvement and five (45%) were in complete remission (Wilcoxon signed-rank test p = 0.006). One patient developed a macular skin rash 1 week after commencing acetarsol, which resolved within 4 weeks of drug cessation. CONCLUSION: Acetarsol was effective for two out of every three patients with refractory proctitis. This cohort had failed a broad range of topical and systemic treatments, including anti-TNFalpha therapy. Clinical efficacy was reflected in significant endoscopic improvement. Adverse effects of acetarsol were rare. PMID- 29457213 TI - Trends in diagnosis of gastroenteropancreatic neuroendocrine tumors (GEP-NETs) in India: A report of multicenter data from a web-based registry. AB - INTRODUCTION: Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are rare tumors. We report data of 407 GEP-NET cases from a neuroendocrine tumor (NET) registry in India. METHODS: The AP-NET registry is an open-label, multicenter, longitudinal observational registry of patients with GEP-NETs in which six tertiary care oncology centers contributed data. Data was prospectively entered in a dedicated computerized database and was reviewed retrospectively. The patients were divided into three cohorts-those diagnosed from 2001 to 2005, from 2006 to 2010, and from 2011 to 2016. RESULTS: Of the 407 cases registered, 37 were in Cohort I, 136 in Cohort II, and 234 in Cohort III. Majority were symptomatic with only 98 patients (24.0%) asymptomatic. The most common presentation of non-functional tumors was abdominal pain (42.4%), while functional tumors presented most commonly with carcinoid syndrome. Use of DOTA PET, introduced in 2011, has increased evaluation in 33.3% patients in Cohort III. The most common primary site was pancreas in all three cohorts. Male preponderance (58.3%) was seen. Histopathological grading was obtained in 230 (56.5%) patients-118 (29%) Grade I, 74 (18.2%) Grade II, and 36 (8.8%) Grade III NET. CONCLUSION: This report highlights changing trends in the diagnosis and reporting of NETs over the last 15 years. PMID- 29457215 TI - The effect of anaesthetic technique during primary breast cancer surgery on neutrophil-lymphocyte ratio, platelet-lymphocyte ratio and return to intended oncological therapy. AB - Inflammation and immunosuppression contribute to the pathogenesis of cancer. An increased neutrophil-lymphocyte ratio reflects these processes and is associated with adverse cancer outcomes. Whether anaesthetic technique for breast cancer surgery influences these factors, and potentially cancer recurrence, remains unknown. We conducted a secondary analysis in patients enrolled in an ongoing trial of anaesthetic technique on breast cancer recurrence. The primary hypothesis was that postoperative neutrophil-lymphocyte ratio is lower in patients allocated to receive propofol-paravertebral rather than inhalational agent-opioid anaesthesia for primary breast cancer surgery. Among 397 patients, 116 had differential white cell counts performed pre-operatively and postoperatively. Pre-operative neutrophil-lymphocyte ratio was similar in the propofol-paravertebral 2.3 (95%CI 1.8-2.8) and inhalational agent-opioid anaesthesia 2.2 (1.9-3.2) groups, p = 0.72. Postoperative neutrophil-lymphocyte ratio was lower (3.0 (2.4-4.2) vs. 4.0 (2.9-5.4), p = 0.001) in the propofol paravertebral group. Propofol-paravertebral anaesthesia attenuated the postoperative increase in the neutrophil-lymphocyte ratio. PMID- 29457214 TI - Maintenance zinc therapy after initial penicillamine chelation to treat symptomatic hepatic Wilson's disease in resource constrained setting. AB - BACKGROUND: Experience with zinc in treating symptomatic hepatic Wilson's disease (WD) is limited. AIM: To study the efficacy of Penicillamine followed by zinc in treating symptomatic hepatic Wilson's disease. METHODS: We retrospectively analyzed case records of 31 symptomatic hepatic WD patients for whom disease severity scores (Child's, model for end-stage liver disease (MELD), Nazer's, and New Wilson Index (NWI) score) and 24-h urinary copper were compared at 3-time points-baseline at presentation, at transition from penicillamine to zinc and at end of follow up. RESULTS: Thirty-one patients (median age 11 [5-24] years) with symptomatic hepatic WD were studied; ten had associated neuropsychiatric manifestations of WD. Penicillamine was changed to zinc sulfate either due to financial constraints (28 patients) or due to adverse effects of penicillamine (3 patients). At presentation (baseline), six patients belonged to Child's class A, five to Child's B, and 17 to Child's C. Duration of initial penicillamine chelation therapy was 134 (2-320) weeks, and of subsequent zinc therapy was 363 (35-728) weeks. There was a significant improvement in liver function tests and disease severity scores (Child's, MELD, Nazer's, and NWI score) at the transition from penicillamine to zinc compared to baseline. This improvement was maintained until the end of study period with 90% survival at 10 (2-20) years. Fifteen of the 17 Child's C cirrhotic patients showed significant improvement in disease severity scores from baseline until end of follow up. CONCLUSIONS: Penicillamine followed by zinc may be a safe and effective treatment in resource-constrained setting for symptomatic hepatic WD patients in all grades of baseline disease severity. Some patients with decompensated cirrhosis due to WD may be managed with medical treatment, avoiding liver transplantation. PMID- 29457216 TI - N-acetylcysteine for major mental disorders: a systematic review and meta analysis of randomized controlled trials. AB - OBJECTIVE: This systematic review and meta-analysis of randomized controlled trials (RCTs) examined the efficacy and safety of adjunctive N-acetylcysteine (NAC), an antioxidant drug, in treating major depressive disorder (MDD), bipolar disorder, and schizophrenia. METHODS: The PubMed, Cochrane Library, PsycINFO, CNKI, CBM, and WanFang databases were independently searched and screened by two researchers. Standardized mean differences (SMDs), risk ratios, and their 95% confidence intervals (CIs) were computed. RESULTS: Six RCTs (n = 701) of NAC for schizophrenia (three RCTs, n = 307), bipolar disorder (two RCTs, n = 125), and MDD (one RCT, n = 269) were identified and analyzed as separate groups. Adjunctive NAC significantly improved total psychopathology (SMD = -0.74, 95% CI: -1.43, -0.06; I2 = 84%, P = 0.03) in schizophrenia, but it had no significant effect on depressive and manic symptoms as assessed by the Young Mania Rating Scale in bipolar disorder and only a small effect on major depressive symptoms. Adverse drug reactions to NAC and discontinuation rates between the NAC and control groups were similar across the three disorders. CONCLUSIONS: Adjunctive NAC appears to be a safe treatment that has efficacy for schizophrenia, but not for bipolar disorder or MDD. Further higher quality RCTs are warranted to determine the role of adjunctive NAC in the treatment of major psychiatric disorders.

AB - Most U.S. preschoolers have consumed media created with funding from the U.S. Department of Education's Ready To Learn (RTL) initiative, which was established to promote school readiness among children ages 2-8. Synthesizing data from 45 evaluations (N = 24,624 unique child participants), this meta-analysis examined the effects of RTL media exposure on young children's literacy skills. Results indicate positive effects of RTL media exposure on children's literacy outcomes, especially vocabulary and phonological concepts. These effects are equivalent to about one-and-a-half months of literacy learning above and beyond typical growth. Findings are robust across a variety of research designs and for exposure to both television and new media. These results are discussed in terms of accountability evidence for RTL and larger debates in scholarly understanding of educational media effects.

AB - Healing of skin wounds is orchestrated by various types of immune cells, but little is known about the role of FoxP3+ regulatory T cells (Tregs) in this process. Here, we determined if Tregs are important for wound healing in normal mice and if they contribute to the accelerated healing of mice overexpressing the growth and differentiation factor activin. Diphtheria toxin induced Treg depletion prior to injury caused impaired healing characterized by delayed reepithelialization, reduced wound contraction, and impaired vessel maturation. The accelerated wound repair of activin-transgenic mice was also abrogated. Mechanistically, we found a strong increase in IL-4 levels combined with overrepresentation of T-bet+ and GATA-3+ alphabeta T cells in Treg-depleted 7-day wounds. In addition, numbers of IFN-gamma- or IL-17A-producing CD4+ and CD4- T cells were elevated. These results demonstrate that Treg depletion in wounds facilitates the expansion of an alphabeta T-cell population with features of Th1 and Th2 cells, and suggest that concomitant changes in the cytokine milieu disturb the healing process. PMID- 29457219 TI - Smokin' hot: adolescent smoking and the risk of psychosis. AB - OBJECTIVE: Daily smoking has been associated with a greater risk of psychosis. However, we are still lacking studies to adjust for baseline psychotic experiences and other substance use. We examined associations between daily smoking and psychosis risk in a 15-year follow-up while accounting for these covariates in a prospective sample (N = 6081) from the Northern Finland Birth Cohort 1986. METHODS: Self-report questionnaires on psychotic experiences (PROD screen), tobacco smoking and other substance use were completed when the cohort members were 15-16 years old. Tobacco smoking was categorized into three groups (non-smokers, 1-9 cigarettes and >=10 cigarettes/day). Psychosis diagnoses were obtained from national registers until the age of 30 years. RESULTS: Subjects in heaviest smoking category were at increased risk of subsequent psychosis (unadjusted HR = 3.15; 95% CI 1.94-5.13). When adjusted for baseline psychotic experiences the association persisted (HR = 2.87; 1.76-4.68) and remained significant even after adjustments for multiple known risk factors such as cannabis use, frequent alcohol use, other illicit substance use, parental substance abuse, and psychosis. Furthermore, number of smoked cigarettes increased psychosis risk in a dose-response manner (adjusted OR = 1.05; 1.01 1.08). CONCLUSION: Heavy tobacco smoking in adolescence was associated with a greater risk for psychosis even after adjustment for confounders. PMID- 29457220 TI - Event-related potentials of emotional and neutral memories: The role of encoding position and delayed testing. AB - Previous research found that memory is not only better for emotional information but also for neutral information that has been encoded in the context of an emotional event. In the present ERP study, we investigated two factors that may influence memory for neutral and emotional items: temporal proximity between emotional and neutral items during encoding, and retention interval (immediate vs. delayed). Forty-nine female participants incidentally encoded 36 unpleasant and 108 neutral pictures (36 neutral pictures preceded an unpleasant picture, 36 followed an unpleasant picture, and 36 neutral pictures were preceded and followed by neutral pictures) and participated in a recognition memory task either immediately (N = 24) or 1 week (N = 25) after encoding. Results showed better memory for emotional pictures relative to neutral pictures. In accordance, enhanced centroparietal old/new differences (500-900 ms) during recognition were observed for unpleasant compared to neutral pictures, most pronounced for the 1 week interval. Picture position effects, however, were only subtle. During encoding, late positive potentials for neutral pictures were slightly lower for neutral pictures following unpleasant ones, but only at trend level. To summarize, we could replicate and extend previous ERP findings showing that emotionally arousing events are better recollected than neutral events, particularly when memory is tested after longer retention intervals. Picture position during encoding, however, had only small effects on elaborative processing and no effects on memory retrieval. PMID- 29457221 TI - Association of STAT6 gene variants with food allergy diagnosed by double-blind placebo-controlled food challenges. AB - This study describes the role of two STAT6 gene variants in food allergy using data of patients and their parents who underwent double-blind placebo-controlled food challenges (DBPCFCs). After quality control, 369 trios were analysed including 262 children (71.0%) with food allergy. Associations were tested by the Family based association test. The A alleles of both SNPs were associated with food allergy (P = .036 and P = .013 for rs324015 and rs1059513, respectively). Furthermore, these A alleles were associated with peanut allergy, higher sIgE levels to both peanut and cow's milk, more severe symptoms and higher eliciting doses during peanut and cow's milk DBPCFCs (all P < .05). In silico analysis indicates that the identified risk variants increase STAT6 expression which stimulates the differentiation of CD4 + T cells to the Th2 subset. In conclusion, STAT6 variants may be involved in the pathophysiology of food allergy and their role seems to be independent of the allergenic food. PMID- 29457222 TI - Extreme dentition does not prevent diet and tooth diversification within combtooth blennies (Ovalentaria: Blenniidae). AB - The dentition of fishes can be quite striking and is often correlated with a specific diet. Combtooth blennies have long incisiform oral teeth, unlike most actinopterygians. It has been suggested that the long tooth morphology is an adaptation for detritivory, but given the diversity of diets (detritus, coral polyps, polychaetes, and pieces of other fishes), are blenny teeth indeed monomorphic? Or does tooth variation associated with diet still exist at this extreme? To explore tooth and diet diversification, we used a new phylogenetic hypothesis of Blenniidae, measured tooth shape, number, and mode of attachment, and quantified blenniid diet. The ancestral diet of blennies contained detritus and diversified into many different diets, including almost exclusively detritivory. Our results reveal a dental cline that may be constrained by tooth shape, but has not prevented diet diversification. Ancestral state reconstruction of tooth morphologies suggests that the ancestor of blennies had many unattached teeth and featured transitions to fewer attached teeth, with several transitions back to attached or unattached teeth. The dentition of blenniids is not monotypic; rather it is diverse and small changes in tooth shape are accompanied by changes in size, number, attachment, and often diet.

AB - Bangladesh has a high prevalence of adolescent pregnancy, but little is known about the nutritional status and dietary practices of Bangladeshi adolescents in early pregnancy or associated factors. We used the baseline data of 1552 pregnant adolescents from a longitudinal, cluster-randomized effectiveness trial conducted in northwest Bangladesh. Forty-four percent of the adolescents were short for their age, 36% had low body mass index, 28% were anemic, 10% had iron deficiency, and 32% had vitamin A deficiency. The mean consumption of animal-source foods was 10.3 times/week. In multivariate analysis, socioeconomic status, education, and food security were generally positively associated with anthropometric indicators and dietary practices but not with iron or vitamin A status. Our findings confirm that there is a high burden of undernutrition among these Bangladeshi adolescents in early pregnancy. Understanding factors related to undernutrition can help to identify adolescent pregnant women at higher risk and provide appropriate counseling and care. PMID- 29457225 TI - Aperture generation based on threshold segmentation for intensity modulated radiotherapy treatment planning. AB - PURPOSE: To reduce computation and decrease planning time with little or no loss in plan quality compared to the column-generation-based (cg) method, a simple method of aperture generation based on threshold segmentation (agts) is proposed. METHODS: The proposed agts strategy consists of two steps. First, a fuzzy controller is used for noise cancellation; then, new apertures are added using the threshold segmentation algorithm. We tested the proposed method on seven prostate tumor cases using the computational environment for radiotherapy research algorithms for the dose calculations and compared the results with those obtained by generating the plan aperture using the cg method. Specifically, the homogeneity index and conformity number of the planning target volume, organs at risk (OARs) sparing, and total planning time were compared among the two methods. RESULTS: The proposed agts technique produced treatment plans approximating the cg solution. Furthermore, the planning time required by the agts method was approximately 58.61% +/- 0.40 less than that required by the cg method. CONCLUSIONS: The agts algorithm can decrease planning time with little or no loss in plan quality compared to the cg method. PMID- 29457226 TI - Coordination and trade-offs among hydraulic safety, efficiency and drought avoidance traits in Amazonian rainforest canopy tree species. AB - Predicting responses of tropical forests to climate change-type drought is challenging because of high species diversity. Detailed characterization of tropical tree hydraulic physiology is necessary to evaluate community drought vulnerability and improve model parameterization. Here, we measured xylem hydraulic conductivity (hydraulic efficiency), xylem vulnerability curves (hydraulic safety), sapwood pressure-volume curves (drought avoidance) and wood density on emergent branches of 14 common species of Eastern Amazonian canopy trees in Paracou, French Guiana across species with the densest and lightest wood in the plot. Our objectives were to evaluate relationships among hydraulic traits to identify strategies and test the ability of easy-to-measure traits as proxies for hard-to-measure hydraulic traits. Xylem efficiency was related to capacitance, sapwood water content and turgor loss point, and other drought avoidance traits, but not to xylem safety (P50 ). Wood density was correlated (r = -0.57 to -0.97) with sapwood pressure-volume traits, forming an axis of hydraulic strategy variation. In contrast to drier sites where hydraulic safety plays a greater role, tropical trees in this humid tropical site varied along an axis with low wood density, high xylem efficiency and high capacitance at one end of the spectrum, and high wood density and low turgor loss point at the other.

PMID- 29457228 TI - Usefulness of ultrasonography in diagnosis, percutaneous management and follow up of post-traumatic scalp pseudoaneurysms. AB - Pseudoaneurysms of the scalp are rare. Most common etiology is trauma. The patients usually present clinically with persistent painful swelling in the scalp few days after the trauma. The lesion may or may not be pulsatile clinically. Ultrasonography (US) is the best modality to assess these pseudoaneurysms. It not only helps in the diagnosis, but also to trace the offending arterial branch and helps in treatment. We present two cases of post-traumatic scalp pseudoaneurysms which were diagnosed with US and were managed by US-guided thrombin injection. Follow up US showed complete resolution. We highlight the importance of US scan in diagnosis, management, and follow up of scalp pseudoaneurysms. PMID- 29457231 TI - It's All Relative. AB - In this issue of the Hastings Center Report, Daniel Brudney suggests that clinicians have an overly deferential attitude toward their patients' surrogate decision-makers that is rooted in a wrongful investment of moral authority. He maintains that surrogate decision-makers have no moral right to decide for their loved ones and that their value in the decision-making process is limited to their knowledge of their loved one's preferences. If operationalized, Brudney's framework would ease the way for clinicians to remove a surrogate who cannot provide information relevant to the patient's preferences and to resort to a paternalistic model of decision-making. Brudney fails to consider that the value of the surrogate does not flow from the surrogate, but rather from the patient's moral claim to have decisions made for him or her by a loved one. This claim recognizes that surrogates have intrinsic value through their relationship to and knowledge of the patient. Bioethics consultation services can assist clinical teams in engaging with the human crowd that surrounds each patient and navigating conflicting values and goals. This relational approach embraces the "mire and blood" that is endemic to relationships and clinical encounters. PMID- 29457230 TI - Impact of hand eczema on quality of life: metropolitan versus non-metropolitan areas. AB - BACKGROUND: An inverse relationship between disease severity and health-related quality of life (HR-QoL) in patients with hand eczema is well established, but modifying effects of demographic variables have been less well studied. OBJECTIVE: To identify the influence of metropolitan versus non-metropolitan residence on the relationship between disease severity and HR-QoL in patients with occupational hand eczema. METHODS: The city of Copenhagen and the rest of Zealand were defined as metropolitan and non-metropolitan areas, respectively. Participants were 773 persons with occupational hand eczema. A questionnaire on the severity of hand eczema and HR-QoL was sent to all participants. RESULTS: The odds for reporting moderate to high severity of occupational hand eczema were significantly lower in the metropolitan population than in the non-metropolitan population [odds ratio (OR): 0.42; 95%CI: 0.23-0.75], whereas low dermatology related quality of life was more prevalent in metropolitan than in non metropolitan patients (OR: 1.31; 95%CI: 0.83-2.05), indicating that hand eczema had a more pronounced negative effect in metropolitan patients, in spite of less severe eczema. CONCLUSION: Our data indicate that area of residence has a modifying effect on the relationship between disease severity and HR-QoL, with a more negative impact on HR-QoL in metropolitan than in non-metropolitan areas. This information is important with respect to fully appreciating the burden of occupational hand eczema. PMID- 29457229 TI - Radiomics analysis of pulmonary nodules in low-dose CT for early detection of lung cancer. AB - PURPOSE: To develop a radiomics prediction model to improve pulmonary nodule (PN) classification in low-dose CT. To compare the model with the American College of Radiology (ACR) Lung CT Screening Reporting and Data System (Lung-RADS) for early detection of lung cancer. METHODS: We examined a set of 72 PNs (31 benign and 41 malignant) from the Lung Image Database Consortium image collection (LIDC-IDRI). One hundred three CT radiomic features were extracted from each PN. Before the model building process, distinctive features were identified using a hierarchical clustering method. We then constructed a prediction model by using a support vector machine (SVM) classifier coupled with a least absolute shrinkage and selection operator (LASSO). A tenfold cross-validation (CV) was repeated ten times (10 * 10-fold CV) to evaluate the accuracy of the SVM-LASSO model. Finally, the best model from the 10 * 10-fold CV was further evaluated using 20 * 5- and 50 * 2-fold CVs. RESULTS: The best SVM-LASSO model consisted of only two features: the bounding box anterior-posterior dimension (BB_AP) and the standard deviation of inverse difference moment (SD_IDM). The BB_AP measured the extension of a PN in the anterior-posterior direction and was highly correlated (r = 0.94) with the PN size. The SD_IDM was a texture feature that measured the directional variation of the local homogeneity feature IDM. Univariate analysis showed that both features were statistically significant and discriminative (P = 0.00013 and 0.000038, respectively). PNs with larger BB_AP or smaller SD_IDM were more likely malignant. The 10 * 10-fold CV of the best SVM model using the two features achieved an accuracy of 84.6% and 0.89 AUC. By comparison, Lung-RADS achieved an accuracy of 72.2% and 0.77 AUC using four features (size, type, calcification, and spiculation). The prediction improvement of SVM-LASSO comparing to Lung-RADS was statistically significant (McNemar's test P = 0.026). Lung-RADS misclassified 19 cases because it was mainly based on PN size, whereas the SVM-LASSO model correctly classified 10 of these cases by combining a size (BB_AP) feature and a texture (SD_IDM) feature. The performance of the SVM-LASSO model was stable when leaving more patients out with five- and twofold CVs (accuracy 84.1% and 81.6%, respectively). CONCLUSION: We developed an SVM-LASSO model to predict malignancy of PNs with two CT radiomic features. We demonstrated that the model achieved an accuracy of 84.6%, which was 12.4% higher than Lung-RADS. PMID- 29457232 TI - Tackling Obesity and Disease: The Culprit Is Sugar; the Response Is Legal Regulation. AB - It is staggering to observe the new normal in America: 37.9 percent of adults are obese, and 70.7 percent are either obese or overweight. One out of every five minors is obese. The real tragedy, of course, is the disability, suffering, and early death that devastates families and communities. But all of society pays, with the annual medical cost estimated at $147 billion. The causal pathways are complex, but if we drill down, sugar is a deeply consequential pathway to obesity, and the single greatest dietary source is sugar-sweetened beverages (SSBs). The copious amount of sugar in the American diet is no accident. Industry practices and regulatory failures have fueled this explosion. Yet there are sensible, effective interventions that would create the conditions for healthier behaviors. What are the key interventions, and how can we overcome the social, political, and constitutional roadblocks? Tobacco control offers a powerful model, suggesting that success requires a suite of interventions working in concert: labeling, warnings, taxation, portion sizes, product formulation, marketing restrictions, and bans in high-risk settings such as schools and hospitals. Each intervention deserves detailed analysis, but I'm kick-starting scholarly and policy conversation by systematically laying out the major legal tools. PMID- 29457233 TI - Market Language, Moral Language. AB - Those who advocate higher out-of-pocket spending, especially high deductibles, to keep health care costs better controlled without losing quality use market language to talk about how people should think about health care. Consumers-that is, patients-should hunt for bargains. Clip coupons. Shop around. Patients need to have more "skin in the game." Consumer-patients will then choose more carefully and prudently and use less unnecessary health care. Unfailingly, "skin" refers to having money at stake. Usually, those arguing for high deductibles express dismay or frustration that patients do not face the full ("true") cost of the health services they receive. Unfortunately, a lack of price transparency, the need to unbundle bundled groups of services to discover total price, and the challenge of validly and reliably measuring and disclosing quality make shopping for health care a challenge for even the savviest patient. Urgency, fear, and sickness that impairs peak cognitive function and other aspects of emotionally laden decision-making, even when "shared" with a physician, add obstacles to coupon clipping and tire kicking. Who has more at stake in health decisions than patients? Whose flesh is literally, not just figuratively, at risk? PMID- 29457234 TI - Community Engagement and Field Trials of Genetically Modified Insects and Animals. AB - New techniques for the genetic modification of organisms are creating new strategies for addressing persistent public health challenges. For example, the company Oxitec has conducted field trials internationally-and has attempted to conduct field trials in the United States-of a genetically modified mosquito that can be used to control dengue, Zika, and some other mosquito-borne diseases. In 2016, a report commissioned by the National Academies of Sciences, Engineering, and Medicine discussed the potential benefits and risks of another strategy, using gene drives. Driving a desired genotype through a population of wild animals or insects could lead to irreversible genetic modification of an entire species. The NASEM report recommends community, stakeholder, and public engagement about potential uses of the technology, and it argues that the engagement should occur as research advances, well before gene drives are deployed. Yet what "engagement" means in practice is unclear. This article seeks clarity on this problem by offering a justification for community engagement and drawing out implications of this argument for the implementation and desired outcomes of community engagement. Community engagement is essential when it comes to research that would release genetically modified insects or animals into the environment. By contrast, obtaining informed consent from people who live near such a proposed field trial is neither necessary nor sufficient. Drawing on the epistemic and moral arguments for deliberative democracy, I propose two discrete mechanisms of community engagement: community advisory boards and deliberative forums, neither of which has been systematically incorporated into research governance. The proposed mechanisms would engender respect for persons who live near field trials, even when the results of deliberation override some individuals' preferences. Community engagement foregrounds the community in our thinking about humans' relationship to nature, and it implies that deciding to release genetically modified insects or animals into the wild ought to be a collective decision, not one made by product developers, policy-makers, private companies, research funders, or scientists alone. PMID- 29457235 TI - The Intimate Responsibility of Surrogate Decision-Making. AB - Daniel Brudney's clear-headed analysis, in this issue of the Hastings Center Report, of the difference between a patient's and a surrogate's right to make medical treatment decisions contributes to a longstanding conversation in bioethics. Brudney offers an epistemological and a moral argument for the patient's and the surrogate's right to decide. The epistemological argument is the same for both parties: the (competent) patient has a right to decide because she is presumed to know her own interests better than anyone else, and the surrogate is entitled to make decisions because she knows the patient better than anyone else. However, argues Brudney, the moral arguments are not parallel. The patient's moral right to decide for herself is an exercise of autonomy, but the only ground for the responsibility held by the surrogate, says Brudney, is that she knows the patient better than the health care professionals do. If in fact that's not the case, then she forfeits her right to be the patient's surrogate. For all the clarity and force of his argument, I think Brudney may be barking up the wrong tree. In cases of proxy decision-making, it's intimacy, not knowledge, that does the heavy moral lifting. PMID- 29457236 TI - Time Is Ethics. AB - Early in my career as a neonatologist, I was called into the hospital for a newborn who would not stop crying. Screaming, really. When I entered the unit, I was greeted by a loud, shrill, distinctive cry. After hearing the history and examining the baby, I just stood there for a while, watching and listening. It took some time, but eventually, I noticed a subtle regularity, a rhythmicity. I took off my watch, placed it on the bed next to the child, and found that the crying briefly grew louder about every six or seven seconds. This baby was having an atypical seizure. This preliminary diagnosis was followed by a conversation with the parents and a neurologist, transfer to the nearby academic center for an extensive evaluation, and the eventual demise of the child from a poorly understood disease. About a year later, I walked into the same unit and heard a cry I had heard only once before. I looked over to see the same mother at a newborn's bedside, with tears in her eyes, looking back at me. She knew what the coming days held for her and for her second child. That was over twenty years ago, but two images, or moments, remain with me. One is the watch on the bed next to the first baby; the other is the mother's expression of sadness the morning the second child was born. The image of the timepiece is perhaps instructive. PMID- 29457238 TI - Rationing Care through Collaboration and Shared Values. AB - Although "rationing" continues to be a dirty word for the public in health policy discourse, Nir Eyal and colleagues handle the concept exactly right in their article in this issue of the Hastings Center Report. They correctly characterize rationing as an ethical requirement, not a moral abomination. They identify the key health policy question as how rationing can best be done, not whether it should be done at all. They make a cogent defense of what they call "rationing through inconvenience" as a justifiable allocational technique. And they wisely call for research on the effectiveness and fairness of this approach and other methods of rationing. I fully agree with their approach to rationing and with their argument that the process they provocatively label "rationing through inconvenience" should not be rejected out of hand. But I believe they have underestimated two ways in which the practical impacts of rationing through inconvenience limit its potential usefulness: the asymmetry of its effect on patients and physicians and the way in which it reduces the capacity of health systems to learn from experience. PMID- 29457239 TI - Patient Care to Public Health to Synthetic Biology. AB - The January-February 2018 issue of the Hastings Center Report includes pieces addressing patient care concerns that lie at the original core of bioethics and pieces that reflect the field's growing breadth. Among the pieces getting at the original core is an article by philosopher Daniel Brudney on the moral values underpinning surrogate decision-making. The article and the two commentaries that follow it contribute to the debate on the moral authority of surrogate decision makers. Several items in the issue take up matters of public health and health policy. For example, the lead article, by Nir Eyal, examines the ethics of using inconvenience-waiting lists and the like-to constrain the consumption of health care services, and a commentary by Lawrence Gostin examines the regulation of sugary beverages. A supplement to the issue contains a special report about the tools and processes used to assess the impact of emerging technologies, with a focus on synthetic biology. PMID- 29457240 TI - Manuscript Reviewers 2017. PMID- 29457241 TI - Can Rationing through Inconvenience Be Ethical? AB - In this article, we provide a comprehensive analysis and a normative assessment of rationing through inconvenience as a form of rationing. By "rationing through inconvenience" in the health sphere, we refer to a nonfinancial burden (the inconvenience) that is either intended to cause or has the effect of causing patients or clinicians to choose an option for health-related consumption that is preferred by the health system for its fairness, efficiency, or other distributive desiderata beyond assisting the immediate patient. We argue that under certain conditions, rationing through inconvenience may turn out to serve as a legitimate and, compared to direct rationing, even a preferable tool for rationing; we propose a research agenda to identify more precisely when that might be the case and when, alternatively, rationing through inconvenience remains ethically undesirable. After defining and illustrating rationing through inconvenience, we turn to its moral advantages and disadvantages over other rationing methods. We take it as a starting assumption that rationing, understood as scarce-resource prioritization, is inevitable and, in a society that has goals beyond optimizing health care for individual patients-such as improving societal health care, education, or overall welfare-prudent and fair. PMID- 29457242 TI - Bioethics as care work. AB - German philosopher Martin Heidegger argued that humans are defined by care. The term he used, "Sorge," picks out a wide range of caring relations, including sorrow, worry, the making of arrangements, and even fending for another. Since coming to The Hastings Center, I've been struck by the genuine care definitive of its scholars' relationship to their work. Care about newborns, the elderly, and nonhuman animals. Care about doctors, nurses, and health care institutions. Care expressed in the panoply of ways biomedical knowledge and practices inform our havings, doings, and beings in the world. Perhaps in its better moments, bioethics just is care work. But care work is hard and messy. PMID- 29457243 TI - Raising the Stakes for Nondiscrimination Protections in the ACA. AB - In the struggle over the durability of the Affordable Care Act, defenders of the ACA stand guard at many fronts. A major contribution of the ACA to nondiscrimination law, however, appears increasingly vulnerable. The ACA established significant new nondiscrimination protections for patients under section 1557 and its implementing regulations. Several of these regulations including protections on the basis of gender identity and pregnancy termination are now under reconsideration at the Department of Health and Human Services, after a nationwide injunction lasting almost a year. Nondiscrimination laws matter, of course, because they promote equal access to health care. But focusing on discriminatory behavior alone is a narrow view of the purpose and potential of nondiscrimination rules-and underestimates the stakes of softening section 1557. To evaluate these protections, we must consider not only their impacts on discriminatory behavior but also their behavioral and attitudinal impacts on patients and communities. This is because supportive or stigmatizing rules can exert an expressive effect: laws communicate information about prevailing social norms, they give some norms greater authority by virtue of the state's support, and they can shape community values. Through these expressive impacts, nondiscrimination laws may affect not only discriminatory behavior in health activities but also the attitudes, beliefs, and decisions of people who are legally protected. PMID- 29457244 TI - The Different Moral Bases of Patient and Surrogate Decision-Making. AB - : My topic is a problem with our practice of surrogate decision-making in health care, namely, the problem of the surrogate who is not doing her job-the surrogate who cannot be reached or the surrogate who seems to refuse to understand or to be unable to understand the clinical situation. The analysis raises a question about the surrogate who simply disagrees with the medical team. One might think that such a surrogate is doing her job-the team just doesn't like how she is doing it. My analysis raises the question of whether (or perhaps when) she should be overridden. In approaching this problem, I focus not on the range of difficulties in practice but on the underlying moral conceptual issue. My concern will be to show that the moral values that underpin patient decision-making are fundamentally different from those that underpin surrogate decision-making. Identifying the distinctions will set parameters for any successful solution to the "Who should decide?" QUESTION: A patient has a specific kind of moral right to make her own medical decisions. A surrogate has no analogous moral right to decide for someone else. We want the surrogate to make the decision because we believe that she has a relevant epistemological advantage over anyone else on the scene. If and when she has no such advantage or if she refuses or is unable to use it, then there might not be sufficient reason to let her be the decision maker. PMID- 29457245 TI - Longitudinal relationships among depressive symptoms, cortisol, and brain atrophy in the neocortex and the hippocampus. AB - OBJECTIVE: Depression is associated with accelerated aging and age-related diseases. However, mechanisms underlying this relationship remain unclear. The aim of this study was to longitudinally assess the link between depressive symptoms, brain atrophy, and cortisol levels. METHOD: Participants from the Betula prospective cohort study (mean age = 59 years, SD = 13.4 years) underwent clinical, neuropsychological and brain 3T MRI assessments at baseline and a 4 year follow-up. Cortisol levels were measured at baseline in four saliva samples. Cortical and hippocampal atrophy rates were estimated and compared between participants with and without depressive symptoms (n = 81) and correlated with cortisol levels (n = 49). RESULTS: Atrophy in the left superior frontal gyrus and right lingual gyrus developed in parallel with depressive symptoms, and in the left temporal pole, superior temporal cortex, and supramarginal cortex after the onset of depressive symptom. Depression-related atrophy was significantly associated with elevated cortisol levels. Elevated cortisol levels were also associated with widespread prefrontal, parietal, lateral, and medial temporal atrophy. CONCLUSION: Depressive symptoms and elevated cortisol levels are associated with atrophy of the prefrontal and limbic areas of the brain.

AB - OBJECTIVE: To determine the rate of radiographic healing, complications, vascularization, and bone density after repair of radial and ulnar fractures in dogs <6 kg that were treated with an autogenous cancellous bone graft (BG) or free autologous omentum graft (OG). STUDY DESIGN: Prospective, randomized, controlled clinical trial with owners/radiologists blinded to treatment. ANIMALS: 25 dogs with naturally occurring traumatic radial/ulnar fractures. METHODS: Fractures underwent plate fixation with OG or BG. Power Doppler ultrasonographic, computed tomographic (CT), and radiographic examinations of the affected antebrachium were performed preoperatively and every 3 weeks postoperatively until healed. Pressure-sensitive walkway gait analysis and owner and veterinarian assessments were obtained preoperatively (0 weeks) and 3, 6, 9, 12, and 24 weeks postoperatively. RESULTS: Owner/veterinarian assessments improved postoperatively but did not differ significantly between groups. The improvement in peak vertical force/vertical impulse was greater in dogs with OG than in those with BG, beginning 3 weeks postoperatively. Radiographic healing occurred earlier in bones treated with OG (median, 9 weeks) than in those treated with BG (12 weeks). Cortical bone density derived from CT of the distal ulna was higher in bones with BG compared with bones with OG. Signal intensity and the number of vessels in the fracture callus declined over time in both groups, according to results of ultrasonography. However, bones retained more vessels and greater signal intensity when treated with OG compared with treatment with BG, according to multiple views at 6 and 9 weeks postoperatively. CONCLUSION: Omental grafting was not associated with major complications, and it accelerated bone healing and return to weight bearing in dogs. CLINICAL SIGNIFICANCE: Omental grafting should be considered as an adjunct to stabilization of antebrachial fractures in toy and small breed dogs. PMID- 29457247 TI - Development of a multiroute physiologically based pharmacokinetic model for orbifloxacin in rabbits. AB - To predict the orbifloxacin concentrations in rabbits after multiple routes of administration, a flow-limited multiroute physiologically based pharmacokinetic (PBPK) model was developed. Three routes of administration (IV, IM, and PO) were incorporated into this model. Physiological parameters including tissue weights and blood flows through different tissues were obtained from the literature. The tissue/plasma partition coefficients (PX s) for noneliminating tissues were calculated according to the area method, while the PX s for kidney and the rest of the body compartment, together with other parameters for absorption and elimination, were optimized based on the published concentrations. The comparisons between predicted and observed orbifloxacin concentrations proved its validity, and the present model predicted available concentration data well, including those in liver, kidney, muscle, lung, heart, and plasma after oral, intravenous, or intramuscular administration. A local sensitivity analysis was also performed, which showed that the parameters for oral absorption were most influential on the orbifloxacin concentrations. This model was used to predict plasma and tissue concentrations after multiple oral or intramuscular administration. This study demonstrated the feasibility of predicting drug residues in minor species after multiple routes of administration in the extra label manner using the PBPK modeling. PMID- 29457248 TI - Duty hours restriction for our surgical trainees: An ethical obligation or a bad idea? AB - To ensure patient safety and protect the well-being of interns and residents, the Accreditation Council for Graduate Medical Education (ACGME) issued guidelines in 2003 limiting the working hours of physician trainees. Although many supported the goals of the ACGME, institutions struggled to restructure their programs and hire staff required by this unfunded mandate. Numerous studies have analyzed the effects of duty hours restrictions on patient outcomes and physician training over the past 15 years. Most agree that duty hours restrictions improved well being of house officers, but these improvements came at the expense of continuity, and patient hand-offs led to medical errors. Effects on resident training are program specific, with duty hours restrictions having the most deleterious effects on surgical disciplines. Because veterinary specialists assume a similar role in providing 24-hour patient care, interns and residents face work-related stress as a result of extended working hours, on-call duty, and an increasingly complex caseload. The North Carolina State Veterinary Hospital is staffed by approximately 100 house officers representing almost every veterinary specialty group. We surveyed departing house officers regarding their quality of life and training experience. Sixty-six percent of interns and residents reported that they do not have time to take care of personal needs, and 57%-62% felt neutral or dissatisfied with their mental and physical well-being. Most trainees believed that decreased duty hours would improve learning, but 42% believed that decreased caseload would be detrimental to training. Veterinary educators must consider post-DVM veterinary training guidelines that maintain patient care with a good learning environment for interns and residents. PMID- 29457249 TI - Gut bacteria of cockroaches are a potential source of antibacterial compound(s). AB - : Here, we hypothesized that the microbial gut flora of animals/pests living in polluted environments, produce substances to thwart bacterial infections. The overall aim of this study was to source microbes inhabiting unusual environmental niches for potential antimicrobial activity. Two cockroach species, Gromphadorhina portentosa (Madagascar) and Blaptica dubia (Dubia) were selected. The gut bacteria from these species were isolated and grown in RPMI 1640 and conditioned media were prepared. Conditioned media were tested against a panel of Gram-positive (Methicillin-resistant Staphylococcus aureus, Streptococcus pyogenes, Bacillus cereus) and Gram-negative (Escherichia coli K1, Salmonella enterica, Serratia marcescens, Pseudomonas aeruginosa, Klebsiella pneumoniae) bacteria, as well as the protist pathogen, Acanthamoeba castellanii. The results revealed that the gut bacteria of cockroaches produce active molecule(s) with potent antibacterial properties, as well as exhibit antiamoebic effects. However, heat-inactivation at 95 degrees C for 10 min had no effect on conditioned media mediated antibacterial and antiamoebic properties. These results suggest that bacteria from novel sources i.e. from the cockroach's gut produce molecules with bactericidal as well as amoebicidal properties that can ultimately lead to the development of therapeutic drugs. SIGNIFICANCE AND IMPACT OF THE STUDY: The bacteria isolated from unusual dwellings such as the cockroaches' gut are a useful source of antibacterial and antiamoebal molecules. These are remarkable findings that will open several avenues in our search for novel antimicrobials from unique sources. Furthermore studies will lead to the identification of molecules to develop future antibacterials from insects. PMID- 29457250 TI - My tribute to Ralph Lazzara, MD.

PMID- 29457252 TI - Body image flexibility: A predictor and moderator of outcome in transdiagnostic outpatient eating disorder treatment. AB - OBJECTIVE: Predictors of attrition and predictors and moderators of outcome were explored in a transdiagnostic sample of patients who received ten-session cognitive behavioral therapy (CBT-T) for nonunderweight eating disorders. Body image flexibility, a protective positive body image construct, was hypothesized to be a significant moderator. METHOD: Data from two case series were combined to form a sample of 78 participants who received CBT-T. Baseline measures of body image, negative affect, personality, and motivation (readiness to change and self efficacy) were included as potential predictors. Global eating disorder psychopathology at each assessment point (baseline, mid- and post-treatment, 1- and 3-month follow-up) was the outcome variable. Predictors of attrition were assessed using logistic regression, and multilevel modeling was applied for predictors and moderators of outcome. RESULTS: Body image flexibility emerged as the strongest predictor and moderator of global eating disorder psychopathology, followed by body image avoidance. Body checking, negative affect, personality beliefs, and self-efficacy were significant predictors of global eating disorder psychopathology. DISCUSSION: Higher body image flexibility predicted lower global eating disorder psychopathology at every assessment point. Further research is required to replicate findings and explore the benefit of focusing on positive body image in treatment. PMID- 29457253 TI - Power transformations improve interpolation of grids for molecular mechanics interaction energies. AB - A common strategy for speeding up molecular docking calculations is to precompute nonbonded interaction energies between a receptor molecule and a set of three dimensional grids. The grids are then interpolated to compute energies for ligand atoms in many different binding poses. Here, I evaluate a smoothing strategy of taking a power transformation of grid point energies and inverse transformation of the result from trilinear interpolation. For molecular docking poses from 85 protein-ligand complexes, this smoothing procedure leads to significant accuracy improvements, including an approximately twofold reduction in the root mean square error at a grid spacing of 0.4 A and retaining the ability to rank docking poses even at a grid spacing of 0.7 A.

AB - AIMS: Primordial odontogenic tumour (POT) is a rare mixed odontogenic neoplasm that is composed of primitive ectomesenchyme resembling dental papilla, surfaced by odontogenic epithelium resembling inner enamel epithelium, without hard tissue formation. Most reported cases have presented in the posterior mandible as a well demarcated radiolucency associated with an unerupted tooth in the first two decades of life. The aim of this report is to describe the clinicopathological features of two more cases of POT. METHODS AND RESULTS: Each presented as an asymptomatic well-delineated radiolucency in the mandible in a 15-year-old female and an 18-year-old male, respectively. Both tumours were composed of a proliferation of plump spindle and stellate cells in delicately collagenous and myxoid stroma, surfaced by columnar-squamous epithelial cells with reverse nuclear polarisation at the tumour periphery. In one case, the formation of abortive tooth germ-like structures was noted. This has not been reported previously and supports the hypothesis of the primordial nature of this tumour. Both patients showed no recurrence at 3- and 20-month follow-up, respectively. CONCLUSION: This report describes two additional cases of POT for a total of 11 cases reported in the English language literature.

PMID- 29457256 TI - Innovation in values based public health nursing student selection: A qualitative evaluation of candidate and selection panel member perspectives. AB - OBJECTIVES: Values based recruitment emerges from the premise that a high degree of value congruence, or the extent to which an individual's values are similar to those of the health organization in which they work, leads to organizational effectiveness. The aim of this evaluation was to explore how candidates and selection panel members experienced and perceived innovative methods of values based public health nursing student selection. DESIGN AND SAMPLE: The evaluation was framed by a qualitative exploratory design involving semi-structured interviews and a group exercise. Data were thematically analyzed. Eight semi structured interviews were conducted with selection panel members. Twenty-two successful candidates took part in a group exercise. INTERVENTION: The use of photo elicitation interviews and situational judgment questions in the context of selection to a university-run public health nursing educational program was explored. RESULTS: While candidates were ambivalent about the use of photo elicitation interviews, with some misunderstanding the task, selection panel members saw the benefits for improving candidate expression and reducing gaming and deception. Situational interview questions were endorsed by candidates and selection panel members due to their fidelity to real-life problems and the ability of panel members to discern value congruence from candidates' responses. CONCLUSIONS: Both techniques offered innovative solutions to candidate selection for entry to the public health nursing education program. PMID- 29457257 TI - Pharmacokinetics, pharmacodynamics, and metabolism of acepromazine following intravenous, oral, and sublingual administration to exercised Thoroughbred horses. AB - Acepromazine is a tranquilizer used commonly in equine medicine. This study describes serum and urine concentrations and the pharmacokinetics and pharmacodynamics of acepromazine following intravenous, oral, and sublingual (SL) administration. Fifteen exercised adult Thoroughbred horses received a single intravenous, oral, and SL dose of 0.09 mg/kg of acepromazine. Blood and urine samples were collected at time 0 and at various times for up to 72 hr and analyzed for acepromazine and its two major metabolites (2-(1-hydroxyethyl) promazine and 2-(1-hydroxyethyl) promazine sulfoxide) using liquid chromatography tandem mass spectrometry. Acepromazine was also incubated in vitro with whole equine blood and serum concentrations of the parent drug and metabolites determined. Acepromazine was quantitated for 24 hr following intravenous administration and 72 hr following oral and SL administration. Results of in vitro incubations with whole blood suggest additional metabolism by RBCs. The mean +/- SEM elimination half-life was 5.16 +/- 0.450, 8.58 +/- 2.23, and 6.70 +/ 2.62 hr following intravenous, oral, and SL administration, respectively. No adverse effects were noted and horses appeared sedate as noted by a decrease in chin-to-ground distance within 5 (i.v.) or 15 (p.o. and SL) minutes postadministration. The duration of sedation lasted 2 hr. Changes in heart rate were minimal. PMID- 29457258 TI - Quality of Prescribing by Physicians, Nurse Practitioners, and Physician Assistants in the United States. AB - OBJECTIVE: Nurse practitioners (NPs) and physician assistants (PAs) have increasingly broad prescribing authority in the United States, yet little is known regarding how the quality of their prescribing practices compares with that of physicians. The objective of this study was to compare the quality of prescribing practices of physicians and nonphysician providers. METHODS: A serial cross-sectional analysis of the 2006-2012 National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey was performed. Ambulatory care services in physician offices, hospital emergency departments, and outpatient departments were evaluated using a nationally representative sample of patient visits to physicians, NPs, and PAs. Main outcome measures were 13 validated outpatient quality indicators focused on pharmacologic management of chronic diseases and appropriate medication use. RESULTS: A total of 701,499 sampled patient visits were included during the study period, representing ~8.33 billion visits nationwide. Physicians were the primary provider for 96.8% of all outpatient visits examined; NPs and PAs each accounted for 1.6% of these visits. The proportion of eligible visits where quality standards were met ranged from 34.1% (angiotensin-converting enzyme inhibitor use for congestive heart failure) to 89.5% (avoidance of inappropriate medications among elderly). The median overall performance across all indicators was 58.7%. On unadjusted analyses, differences in quality of care between nonphysicians and physicians for each indicator did not consistently favor one practitioner type over others. After adjustment for potentially confounding patient and provider characteristics, the quality of prescribing by NPs and PAs was similar to the care delivered by physicians for 10 of the 13 indicators evaluated, and no consistent directional association was found between provider type and indicator fulfillment for the remaining measures. CONCLUSIONS: Although significant shortfalls exist in the quality of ambulatory prescribing across all practitioner types, the quality of care delivered by nonphysicians and physicians was generally comparable. PMID- 29457259 TI - Prosthetic mitral valve thrombosis, malfunction, and paroxysmal mitral regurgitation. AB - Intermittent dysfunction of mechanical mitral valve prosthesis is an uncommon condition. It carries serious clinical implications if unrecognized. Here, we present a case of a 28-year-old female with a history of rheumatic multivalvular disease, for which she had undergone double valve replacement and tricuspid annuloplasty. Six months later, she presented with heart failure. Clinical examination revealed intermittent loss of closing clicks followed by a pansystolic murmur at the apex, suggestive of mitral prosthetic valve dysfunction. We highlight the echocardiographic findings of paroxysmal mitral valvular regurgitation secondary to prosthetic valve malfunction secondary to prosthetic valve thrombosis. PMID- 29457260 TI - Prediction of postoperative atrial fibrillation with left atrial mechanical functions and NT-pro ANP levels after coronary artery bypass surgery: A three dimensional echocardiography study. AB - OBJECTIVE: Postoperative AF (POAF) is the most common cause of morbidity after coronary artery bypass surgery. In this study, we aimed to show the relationship between POAF and N-terminal pro-atrial natriuretic peptide (NT-pro ANP) levels and the relationship between mechanical functions and left atrial volume measured using preoperative three-dimensional echocardiography (3D ECHO) among patients that will undergo isolated coronary artery bypass grafting (CABG) in elective conditions. METHOD: Sixty-six consecutive patients (51 male, 15 female) who were decided to undergo CABG and had normal sinus rhythm were involved in the study. Patients were followed by continuous electrocardiography monitoring and daily electrocardiogram. LA volume and mechanical functions were calculated with 3D ECHO. In addition, for the analysis of plasma levels of NT-pro ANP, blood samples were collected before the surgery. RESULTS: During follow-up after the operation, 15 patients (22.7%) had postoperative atrial fibrillation. LA Vmax, Vmin, VpreA values were higher (P < .001, P = .004, P < .001 respectively) Also in POAF developed group and SR group, LAVI values were 27.56 +/- 4.2 and 20.7 +/- 4.64 mL/m2 , respectively (P < .001). In POAF-developing group, NT-pro ANP levels were significantly higher (P < .001). In multiple logistic regression analysis, age (beta = 0.355, P = .007) and LAVI (beta = 0.668, P = .012) are independent predictors of POAF. CONCLUSION: It was found that 3D echocardiography can be used as a helping noninvasive method to show subclinical atrial volume and mechanical dysfunction in patients undergoing CABG. Also, blood levels of NT-pro ANP in POAF group were increased. PMID- 29457261 TI - Angiography vs transesophageal echocardiography-guided patent foramen ovale closure: A propensity score matched analysis of a two-center registry. AB - OBJECTIVES: The purpose of this study is to compare the long-term outcomes of patent foramen ovale (PFO) closure using angiography or transesophageal echocardiography as procedural guidance. BACKGROUND: The interventional treatment is emerging as a safe and efficient option for patients with high likelihood of PFO-related cryptogenic stroke and high risk of recurrence. The "gold-standard" guidance technique remains an issue. METHODS: Two cohorts of patients undergoing PFO closure for cryptogenic stroke in two catheterization laboratories of the same institution, using similar inclusion criteria but different guidance, were compared with propensity score matching. RESULTS: A total of 374 patients were enrolled, 161 in Angio-group and 213 in Echo-group. No difference was detected in the procedural complication rate. In Angio-group, radiological exposure (P = .001) and 6-month residual shunt (16.8% vs 8.0%, P = .015) were higher. After a mean follow-up of 41 +/- 30 months, 28 patients (7.5%) presented any adverse event (death, recurrent cerebral ischemia, device-related complications, reintervention), with a higher rate in Angio-group (13.0% vs 3.3%, P = .001), mainly due to repeated percutaneous intervention (10.6% vs 1.4%, P = .001). The results were confirmed after propensity score matching (118 patients/group). The rate of recurrent cerebral ischemia was 1.9% and was not significantly different in the two groups. Intra-procedural guidance and atrial septum aneurysm were independent predictors of the composite primary endpoint (OR 1.2, P = .016). CONCLUSIONS: The use of intra-procedural transesophageal echocardiography (TEE) guidance for PFO closure allows lower residual shunt rate, radiological exposure, and adverse events, mainly driven by a significant reduction in percutaneous reintervention. PMID- 29457262 TI - Handheld reflectance confocal microscopy, dermatoscopy and histopathological correlation of common inflammatory balanitis. AB - BACKGROUND: The term balanitis includes a variety of inflammatory skin diseases involving the glans penis whose clinical diagnosis may be challenging. A biopsy is often required to obtain a definitive diagnosis, although it is barely accepted by patients. Reflectance confocal microscopy (RCM), that provides a real time, en face imaging of the epidermis and upper dermis, is currently utilized for the diagnosis of some neoplastic and inflammatory skin diseases. The aim of this study was to analyze the RCM handheld findings of some common balanitis and to correlate them with dermatoscopy and histopathological features. MATERIALS AND METHODS: Thirty-two patients with biopsy-proven diagnosis of psoriatic balanitis (10 patients), Zoon's balanitis (11 patients) and lichen sclerosus et atrophicus (11 patients) were evaluated using a handheld RCM device and *10 dermatoscopy. RESULTS: At the end of the study, each disorder presented specific RCM patterns that correlated with dermatoscopy and histopathological findings. CONCLUSION: The use of handheld RCM as complementary tool in everyday clinical practice for the evaluation of inflammatory diseases involving sensitive areas such as male genitalia, may contribute to reduce the need of invasive procedures. PMID- 29457263 TI - Acute myocarditis with thrombus near left ventricular outflow tract. AB - A young woman presented with fulminant heart failure. Transthoracic echocardiography revealed severe left ventricular dysfunction with a mass adjacent to the basal anterior wall, near the left ventricular outflow tract (LVOT). The cause of the acute heart failure and mass was unclear. Transesophageal echocardiography, with contrast, and cardiac magnetic resonance imaging findings were consistent with thrombus near the LVOT. Cardiac biopsy suggested giant cell myocarditis. The patient was treated with anticoagulation, steroids, and heart failure medications with resolution of the thrombus. This case was remarkable for the location of thrombus at the base of the ventricle. PMID- 29457264 TI - Comparison of left atrial size and function in hypertrophic cardiomyopathy and in Fabry disease with left ventricular hypertrophy. AB - BACKGROUND: Fabry disease (FD) and hypertrophic cardiomyopathy (HCM) are two diseases with a different pathophysiology, both cause left ventricular hypertrophy (LVH) and myocardial fibrosis. Although remodeling and systolic dysfunction of the left atrium (LA) are associated with atrial fibrillation and stroke in HCM, changes in the size and function of the LA have not been well studied in FD with LVH. METHODS: The following groups were studied prospectively, and their respective findings compared: 19 patients with non-obstructive HCM (Group I), 20 patients with a diagnosis of Fabry cardiomyopathy (Group II), and 20 normal subjects matched for sex and age (Group III). Left ventricular mass index was measured using Devereux' formula, left atrial volume with Simpson's biplane method and left atrial mechanical function, including strain and strain rate, was measured using the speckle tracking technique. Strain and strain rate of the reservoir were measured during the three phases: reservoir (SR S), passive conduit (SR E) and atrial contraction (SR A). RESULTS: Patients with HCM had a larger left atrial volume than patients with FD (48.16 +/- 14.3 mL/m2 vs 38.9 +/- 14.9 mL/m2 respectively, P < .001), but in both disorders there was a severe decrease in left atrial function: reservoir strain in the apical four-chamber view: 17.47% in HCM vs 22.5% in FD, P = .24), strain rate in the apical chamber view: SR A: -0.80/seconds in HCM vs -1.04/seconds in FD (P = .88), SR S: 0.69/seconds in HCM vs 0.93 in FD (P = .12), SR E: -0.80 seconds in HCM vs 0.97/seconds in FD (P = .18). CONCLUSIONS: In this echocardiographic study we used speckle tracking to assess left atrial mechanical function and showed that FD is associated to an atrial cardiomyopathy, affecting the three phasic functions of the LA. Although in patients with HCM left atrial volume is larger than in patients with FD, both disorders exhibit severe decrease in left atrial function. These findings should be considered, given the potentially serious complications that can occur with the two diseases. PMID- 29457265 TI - The role of type 2 diabetes mellitus on hypertensive-related aortic stiffness. AB - BACKGROUND: Hypertension is strongly related to arterial stiffness in a cause effect fashion. Diabetes mellitus is also thought to determine vascular damage, mostly by means of advanced glycosylation end-products (AGEs). Aim of our study was to study the role of type 2 diabetes mellitus (T2DM) as regard ascending aortic elastic properties in hypertensive patients. METHODS: We prospectively enrolled outpatients with hypertension (n = 99) and type 2 diabetes mellitus plus hypertension (n = 42) without cardiovascular events. They underwent a transthoracic echocardiography to measure aortic diameters, aortic elastic properties (ie, compliance, distensibility, stiffness index, Peterson's elastic modulus, pulse wave velocity, M-mode strain), tissue Doppler imaging (TDI) to calculate diastolic (E' and A') and systolic (S') velocities, and tissue strain. Multivariable analysis was run to assess the association between T2DM and these variables after correcting for possible confounders (age, sex, body mass index [BMI], dyslipidemia). RESULTS: The two groups did not differ as regards age, sex, BMI, and blood pressure. However, T2DM patients were more likely to be dyslipidemic (43% vs 71%, P = .003). Aortic diameters were similar in the two groups, but the aortic elastic properties significantly more impaired in T2DM group. At multivariable analysis, stiffness index, Peterson's elastic modulus, the TDI waves, and the tissue strain remained associated with the co-presence of T2DM and hypertension. CONCLUSION: Our data suggest that people suffering from both T2DM and hypertension have more impaired aortic elastic properties than those hypertensive alone. Considering the prognostic role of aortic stiffness, these patients may benefit from a closer follow-up. PMID- 29457266 TI - Polyvalvular heart disease syndrome.

The characteristic facies and echocardiographic features of this rare autosomal dominant connective tissue disorder are presented. PMID- 29457267 TI - Involving children and young people in clinical research through the forum of a European Young Persons' Advisory Group: needs and challenges. AB - Children and young people are seen as fundamental to the design and delivery of clinical research as active and reflective participants. In Europe, involvement of children and young people in clinical research is promoted extensively in order to engage young people in research as partners and to give them a voice to raise their own issues or opinions and for their involvement in planning and decision making in addition to learning research skills. Children and young people can be trained in clinical research through participation in young person advisory groups (YPAGs). Members of YPAGs assist other children and young people to learn about clinical research and share their experience and point of view with researchers, thereby possibly influencing all phases of research including the development and prioritization of research questions, design and methods, recruitment plans, and strategies for results dissemination. In the long term, the expansion of YPAGs in Europe will serve as a driving force for refining pediatric clinical research. It will help in a better definition of research projects according to the patients' needs. Furthermore, direct engagement of children and young people in research will be favorable to both researchers and young people. PMID- 29457268 TI - The lymphoid cell network in the skin. AB - Cutaneous immunity represents a crucial component of the mammalian immune response. The presence of a large array of commensal microorganisms along with a myriad of environmental stresses necessitates constant immuno-surveillance of the tissue. To achieve a perfect balance between immune-tolerance and immune activation, the skin harbors strategically localized immune cell populations that modulate these responses. To maintain homeostasis, innate and adaptive immune cells assimilate microenvironmental cues and coordinate cellular and molecular functions in a spatiotemporal manner. The role of lymphoid cells in cutaneous immunity is gaining much appreciation due to their important roles in regulating skin health and pathology. In this review, we aim to highlight the recent advances in the field of cutaneous lymphoid biology. PMID- 29457269 TI - Ambulatory blood pressure monitoring in living kidney donors: What changes in 10 years? AB - In renal transplantation, living donations have more significant benefits compared to cadaveric donations. However, a probable increase in blood pressure following donation should also be kept in mind. In this study, we investigated the long-term changes in blood pressure in living kidney donors using ambulatory blood pressure monitoring and we explored the e-GFR and albuminuria/proteinuria measurements at 3 time points. Twenty-eight living kidney donors and 39 healthy individuals were evaluated and compared at the baseline and later at the 10th year. At the 10th year, creatinine levels were higher and eGFR levels were lower in the donors, whereas the systolic and diastolic measurements of the donors and controls and the prevalence of nondipping in the donors and controls were similar. Our study may be underpowered due to its small population size. However, our results at the 10th year follow-up indicated that the risk of hypertension might not seem to have increased in the well-selected donors. In addition, the majority of our donors had preserved their GFR values. Therefore, we can suggest that living kidney donation appears to be safe in well-selected patients over a 10-year time frame. PMID- 29457271 TI - Does the temperature of an artificial tear affect its comfort? AB - BACKGROUND: Refrigerated eye-drops have been advocated in cases of ocular allergies to provide a soothing effect upon instillation. This notion continues to be promoted by practitioners for artificial tears (AT) in the management of dry eye (DE) with little support in the literature. To further substantiate claims of a soothing effect of cold eye-drops, the aim of this study was to determine if refrigeration of an AT enhanced the subjective comfort upon instillation. METHODS: Participants with mild to moderate DE participated in an open label contralateral study of two weeks duration. Each participant instilled Systane Ultra (Alcon Laboratories) in the morning (between 6.00-10.00 hours) and in the evening (between 18.00-22.00 hours). Participants were asked to report the subjective comfort immediately after both of these instillations, on a scale from 1 (poor) to 10 (excellent). This was done for ambient (aAT) and refrigerated (rAT) drops. An in vitro study evaluated if there were any changes in eye-drop pH and osmolarity with refrigeration. RESULTS: Participants (n = 18, three male, 15 female, age 22-28 years, average 24.4 +/- 1.6) reported mean comfort scores (+/- standard deviation) of 7.8 +/- 0.9 and 7.6 +/- 1.4, for the aAT and the rAT, respectively. Mean comfort scores (+/- standard deviation) for morning and evening, were 7.7 +/- 1.2 and 7.8 +/- 1.1, respectively. A non-parametric Friedman test of differences among repeated measures was conducted and rendered a chi-squared value of 3.74, which was not statistically significant (p = 0.29). The pH remained stable at 8.0 and the osmolality did not vary significantly with refrigeration. CONCLUSION: There is no advantage, with respect to patient perceived comfort, in refrigerating the Systane Ultra (Alcon Laboratories) AT for mild to moderate DE. PMID- 29457270 TI - Clinical and echocardiographic characteristics of patients in sinus rhythm, normal left ventricular function, and indeterminate diastolic function. AB - BACKGROUND: Diastolic dysfunction (DDFx) is the major underlying mechanism of heart failure with preserved left ventricular ejection fraction (EF). Yet, the echocardiographic diagnosis of DDFx in patients in sinus rhythm is challenging and up to 25% of studies have discrepant measures making assessment of DDFx indeterminate. We aimed to describe the clinical and echocardiographic characteristics of patients with indeterminate diastolic function compared to patients with definite normal and abnormal diastolic function. METHODS: One thousand six hundred seventy-four patients were identified from the echocardiography database in sinus rhythm, EF >= 45% without wall-motion abnormalities, valvular, congenital heart diseases, cardiomyopathies or pulmonary disease. Patients were divided according to their lateral mitral E/E' ratio and left atrial systolic diameter: normal diastolic function (DFx) (left atrial systolic diameter [LASd] <40 mm, E/E' < 10), DDFx (LASd >= 40 mm, E/E' >= 10) and indeterminate DFx (discrepant LASd diameter and E/E' ratio). RESULTS: Clinical and echocardiographic characteristics of the 3 groups, DDFx (n = 186), indeterminate diastolic function (IndtDFx) (n = 207), and normal diastolic function (NDFx) (n = 1281) were significantly different. IndtDFx demonstrated intermediate parameter abnormalities, largely overlapping with DDFx. LASd and E/E' were similarly associated with the inability to determine diastolic function. Age, female gender, renal failure, E/E' and pulmonary pressure were found to be independent predictors of heart failure symptoms (RR = 1.02, 1.5, 2.5, 1.1, 1.1, respectively, P < .0001, r = .35). CONCLUSION: Clinically and echocardiographically patients with IndtDFx are more closely related to DDfx than to NDFx. Although LAd was abnormal in IndtDFx it was not predictive of heart failure symptoms. Further study is suggested to establish whether LA function rather than its maximal size can provide additional information. PMID- 29457272 TI - Atopic dermatitis in diverse racial and ethnic groups-Variations in epidemiology, genetics, clinical presentation and treatment. AB - Atopic dermatitis (AD) is a chronic inflammatory skin condition that affects diverse ethnic groups with varying prevalence. Despite a predominance of studies in individuals of European ancestry, AD has been found to occur more frequently in Asian and Black individuals than Whites. Therefore, an understanding of the unique clinical features of AD in diverse ethnic groups, as well as the differences in genetic polymorphisms that influence susceptibility to AD and response to current therapies, is paramount for management of an increasingly diverse patient population. In this article, we review key nuances in the epidemiology, pathophysiology, clinical presentation and treatment of AD in non White ethnic groups, which are largely underappreciated in the literature. We highlight the need for studies evaluating the tissue molecular and cellular phenotypes of AD in non-White patients, as well as greater inclusion of minority groups in clinical trials, to develop targeted treatments for a multi-ethnic population. PMID- 29457273 TI - Clinical Risk Factors for Early Seizure Recurrence in Dogs Hospitalized for Seizure Evaluation. AB - BACKGROUND: Epileptic seizures are a common cause for neurological evaluations in dogs. HYPOTHESIS/OBJECTIVES: To determine the timing, frequency, and risk factors for early seizure recurrence (ESR) among dogs admitted to the hospital for seizure evaluation and to facilitate rapid decision making about whether dogs should be placed in the intensive care unit (ICU) or day ward. ANIMALS: Nine hundred twenty-two dogs referred for seizure investigation; 214 patients were included. METHODS: Retrospective study. Medical records between 2000 and 2017 were reviewed to determine risk factors for ESR. Findings were compared among dogs diagnosed with idiopathic epilepsy (IE), structural epilepsy (StE) and reactive seizures (RS), as well as in all selected cases together. RESULTS: Fifty percent of dogs had a seizure while hospitalized. In the group 53.1 and 52.2% in the StE group, whereas in the RS 40.44% had ESR. The average time to ESR was 7 hours. In IE group, abnormal postictal neurological examination with prosencephalon signs predicted ESR. In StE group, a single generalized or focal seizure 72 hours before hospital admission and abnormal neurologic examination predicted ESR. In the RS group, ERS was predicted by long-term antiepileptic monotheraphy. When all dogs were analyzed together, abnormal neurological examination, the occurrence of cluster seizures, status epilepticus, or combination of them 72 hours before presentation predicted ESR. CONCLUSIONS AND CLINICAL IMPORTANCE: Epileptic seizures recurred in 50% of patients within a mean time of 7 hours. In general, when cluster seizures, status epilepticus or both occurred 72 hours before presentation and neurological examination was abnormal upon presentation, the dog should be placed in ICU for observation.

PMID- 29457274 TI - Impact of the kidney allocation system on young pediatric recipients. AB - The kidney allocation system (KAS) altered pediatric candidate prioritization. We determined KAS's impact on pediatric kidney recipients by examining delayed graft function (DGF) rates from 2010 to 2016. A propensity score-matched pediatric recipients pre- and post-KAS. A semiparametric decomposition analysis estimated the contributions of KAS-related changes in donor characteristics and dialysis time on DGF rate. The unadjusted odds of DGF were 69% higher post-KAS for young (<10 years at listing) recipients (N = 1153, P = .02) but were not significantly increased for older pediatric (10-17 years at listing) recipients (N = 2624, P = .48). Post-KAS, young recipients received significantly fewer pediatric (<18 years) donor kidneys (21% vs 32%, P < .01) and had longer median pretransplant dialysis time (603 vs 435 days, P < .01). After propensity score matching, post KAS status increased the odds of DGF in young recipients 71% (OR 1.71, 95% CI 1.01-2.46). In decomposition analysis, 24% of the higher DGF rate post-KAS was attributable to donor characteristics and 19% to increased recipient dialysis time. In a confirmatory survival analysis, DGF was associated with a 2.2 times higher risk of graft failure (aHR2.28, 95% CI 1.46-3.54). In conclusion, KAS may lead to worse graft survival outcomes in children. Allocation changes should be considered.

AB - Eradicating cancer stem cells (CSCs) in colorectal cancer (CRC) through differentiation therapy is a promising approach for cancer treatment. Our retrospective tumor-specimen analysis elucidated alteration in the expression of bone morphogenetic protein 2 (BMP-2) and beta-catenin during the colon cancer progression, indicating that their possible intervention through "forced differentiation" in colon cancer remission. We reveal that Abrus agglutinin (AGG) induces the colon CSCs differentiation, and enhances sensitivity to the anticancer therapeutics. The low dose AGG (max. dose = 100 ng/mL) decreased the expression of stemness-associated molecules such as CD44 and beta-catenin in the HT-29 cell derived colonospheres. Further, AGG augmented colonosphere differentiation, as demonstrated by the enhanced CK20/CK7 expression ratio and induced alkaline phosphatase activity. Interestingly, the AGG-induced expression of BMP-2 and the AGG-induced differentiation were demonstrated to be critically dependent on BMP-2 in the colonospheres. Similarly, autophagy-induction by AGG was associated with colonosphere differentiation and the gene silencing of BMP-2 led to the reduced accumulation of LC3-II, suggesting that AGG-induced autophagy is dependent on BMP-2. Furthermore, hVps34 binds strongly to BMP-2, indicating a possible association of BMP-2 with the process of autophagy. Moreover, the reduction in the self-renewal capacity of the colonospheres was associated with AGG-augmented autophagic degradation of beta-catenin through an interaction with the autophagy adaptor protein p62. In the subcutaneous HT-29 xenograft model, AGG profoundly inhibited the growth of tumors through an increase in BMP-2 expression and LC3-II puncta, and a decrease in beta-catenin expression, confirming the antitumor potential of AGG through induction of differentiation in colorectal cancer. PMID- 29457277 TI - Polymorphisms of CYP27B1 are associated with IFN efficacy in HBeAg-positive patients. AB - BACKGROUND: Host single nucleotide polymorphisms were associated with antiviral therapy in CHB patients. The CYP27B1 gene, encoding 25(OH)D3 -1alpha hydroxylase, might activate 25(OH)D3 to 1,25(OH)2 D3 in kidney resulted in influencing the efficacy of interferon (IFN). The aim of the study was to investigate the association between CYP27B1 polymorphisms and the response to IFN in HBeAg positive patients. METHODS: Eighty-seven HBeAg-positive CHB patients infected with HBV genotype B or C were included in the study. All patients were treated with IFN at least 1 year. According to the response to PEG-IFN therapy, they were divided into three groups: 16 complete responses (CR), 42 partial responses (PR), and 29 nonresponses (NR). Sanger-sequencing was utilized to genotype the CYP27B1 SNPs(rs4646536 and rs10877012). RESULTS: In logistic regression analysis, the frequency of rs4646536 CC genotype was observed to be higher in the NR group. Besides, the GG genotype of rs10877012 differed significantly among the three groups. The GG genotype was prevalent in patients with CR, and patients with TT genotype result in NR at the end of IFN treatment. The most common haplotype TG was independently associated with CR, after adjustment, and haplotype CT appeared to be associated with NR and PR, rather than CR. The data also showed that patients with baseline 1,25(OH)2 D3 > 39.39 pg/mL had higher CR rates at the end of IFN therapy. CONCLUSION: These results suggested CYP28B1 gene polymorphisms may be independently associated with the efficacy of IFN in HBeAg-positive patients. PMID- 29457278 TI - Zwitterionic Nanocages Overcome the Efficacy Loss of Biologic Drugs. AB - For biotherapeutics that require multiple administrations to fully cure diseases, the induction of undesirable immune response is one common cause for the failure of their treatment. Covalent binding of hydrophilic polymers to proteins is commonly employed to mitigate potential immune responses. However, while this technique is proved to partially reduce the antibodies (Abs) reactive to proteins, it may induce Abs toward their associated polymers and thus result in the loss of efficacy. Zwitterionic poly(carboxybetaine) (PCB) is recently shown to improve the immunologic properties of proteins without inducing any antipolymer Abs against itself. However, it is unclear if the improved immunologic profiles can translate to better clinical outcomes since improved immunogenicity cannot directly reflect amelioration in efficacy. Here, a PCB nanocage (PCB NC) is developed, which can physically encase proteins while keeping their structure intact. PCB NC encapsulation of uricase, a highly immunogenic enzyme, is demonstrated to eradicate all the immune responses. To bridge the gap between immunogenicity and efficacy studies, the therapeutic performance of PCB NC uricase is evaluated and compared with its PEGylated counterpart in a clinical-mimicking gouty rat model to determine any loss of efficacy evoked after five administrations. PMID- 29457279 TI - Lysophosphatidylserine suppression of T-cell activation via GPR174 requires Galphas proteins. AB - G protein-coupled receptors regulate diverse aspects of T-cell activity and effector function. Recently, we showed that GPR174 mediates the suppression of T cell proliferation in vitro induced by the polar lipid lysophosphatidylserine (LysoPS). Here, we investigated the in vivo activity of this pathway and characterized the mechanisms involved. Using in vivo models of T-cell proliferation induced by sublethal irradiation or regulatory T-cell depletion, we show that GPR174 expression can constrain T-cell proliferation. In vitro experiments established that Galphas G proteins are needed for LysoPS/GPR174 mediated suppression of T-cell proliferation. Mechanistically, LysoPS acts via GPR174 and Galphas to suppress IL-2 production by activated T cells and limit upregulation of the activation markers CD25 and CD69. Together, our findings identify GPR174 as an abundantly expressed Galphas-dependent receptor that can negatively regulate naive T-cell activation. See also: News and Commentary by Robert & Mackay. PMID- 29457280 TI - Continuous blood purification ameliorates clinical signs and corrects the plasma phospholipid levels of patients with multiple organ dysfunction syndromes. AB - BACKGROUND: Multiple organ dysfunction syndromes (MODS) is reported as a leading cause of mortality in intensive care units. Recently, continuous blood purification (CBP) has been mostly applied for MODS treatment. Thus, the purpose of this study was to investigate the effects of CBP on plasma phospholipid level in patients with MODS. METHODS: A total of 126 patients with MODS and 120 healthy people were collected. The serum cytokine levels, blood biochemical parameters, and blood gas indexes were detected, and the correlation among phospholipid compounds with serum cytokine levels, blood biochemical parameters, and blood gas indexes was analyzed. RESULTS: Before CBP, levels of body temperature, RR, HR, CVP, IL-6, IL-10, TNF-alpha, BUN, SCr, PaCO2 , SM747, and LPC540 were obviously higher, and pH, HCO3- , PaO2 , SaO2 , PE750, PI885, PC792, PC826, PC830, PC854, PC802, and PG747 were lower in the MODS group than those in the control group. During CBP, the MODS group had gradually declined RR, CVP, levels of IL-6, IL-10 and TNF-alpha, BUN, SCr, PaCO2 , SM747, and LPC540 and increased HCO3- , PaO2 and SaO2 , PE750, PI885, PC792, PC826, PC830, PC854, PC802, and PG747. Besides, levels of PE750, PI885, PC792, PC826, PC830, PC854, PC802, and PG747 had an obvious negative correlation with levels of TNF-alpha, IL-10, IL-6, BUN, SCr, and PaCO2 , and a significant positive correlation with levels of HCO3- , PaO2 , and SaO2 . CONCLUSION: CBP could effectively ameliorate clinical signs of patients with MODS and correct the plasma phospholipid levels. PMID- 29457281 TI - Vitrimer Elastomer-Based Jigsaw Puzzle-Like Healable Triboelectric Nanogenerator for Self-Powered Wearable Electronics. AB - Functional polymers possess outstanding uniqueness in fabricating intelligent devices such as sensors and actuators, but they are rarely used for converting mechanical energy into electric power. Here, a vitrimer based triboelectric nanogenerator (VTENG) is developed by embedding a layer of silver nanowire percolation network in a dynamic disulfide bond-based vitrimer elastomer. In virtue of covalent dynamic disulfide bonds in the elastomer matrix, a thermal stimulus enables in situ healing if broken, on demand reconfiguration of shape, and assembly of more sophisticated structures of VTENG devices. On rupture or external damage, the structural integrity and conductivity of VTENG are restored under rapid thermal stimulus. The flexible and stretchable VTENG can be scaled up akin to jigsaw puzzles and transformed from 2D to 3D structures. It is demonstrated that this self-healable and shape-adaptive VTENG can be utilized for mechanical energy harvesters and self-powered tactile/pressure sensors with extended lifetime and excellent design flexibility. These results show that the incorporation of organic materials into electronic devices can not only bestow functional properties but also provide new routes for flexible device fabrication. PMID- 29457282 TI - A Simple, General Synthetic Route toward Nanoscale Transition Metal Borides. AB - Most nanomaterials, such as transition metal carbides, phosphides, nitrides, chalcogenides, etc., have been extensively studied for their various properties in recent years. The similarly attractive transition metal borides, on the contrary, have seen little interest from the materials science community, mainly because nanomaterials are notoriously difficult to synthesize. Herein, a simple, general synthetic method toward crystalline transition metal boride nanomaterials is proposed. This new method takes advantage of the redox chemistry of Sn/SnCl2 , the volatility and recrystallization of SnCl2 at the synthesis conditions, as well as the immiscibility of tin with boron, to produce crystalline phases of 3d, 4d, and 5d transition metal nanoborides with different morphologies (nanorods, nanosheets, nanoprisms, nanoplates, nanoparticles, etc.). Importantly, this method allows flexibility in the choice of the transition metal, as well as the ability to target several compositions within the same binary phase diagram (e.g., Mo2 B, alpha-MoB, MoB2 , Mo2 B4 ). The simplicity and wide applicability of the method should enable the fulfillment of the great potential of this understudied class of materials, which show a variety of excellent chemical, electrochemical, and physical properties at the microscale. PMID- 29457283 TI - Direct Visualization of the Reversible O2- /O- Redox Process in Li-Rich Cathode Materials. AB - Conventional cathodes of Li-ion batteries mainly operate through an insertion extraction process involving transition metal redox. These cathodes will not be able to meet the increasing requirements until lithium-rich layered oxides emerge with beyond-capacity performance. Nevertheless, in-depth understanding of the evolution of crystal and excess capacity delivered by Li-rich layered oxides is insufficient. Herein, various in situ technologies such as X-ray diffraction and Raman spectroscopy are employed for a typical material Li1.2 Ni0.2 Mn0.6 O2 , directly visualizing O- ?O- (peroxo oxygen dimers) bonding mostly along the c axis and demonstrating the reversible O2- /O- redox process. Additionally, the formation of the peroxo O?O bond is calculated via density functional theory, and the corresponding O?O bond length of ~1.3 A matches well with the in situ Raman results. These findings enrich the oxygen chemistry in layered oxides and open opportunities to design high-performance positive electrodes for lithium-ion batteries. PMID- 29457284 TI - Dual-Peak Absorbing Semiconducting Copolymer Nanoparticles for First and Second Near-Infrared Window Photothermal Therapy: A Comparative Study. AB - Near-infrared (NIR) light is widely used for noninvasive optical diagnosis and phototherapy. However, current research focuses on the first NIR window (NIR-I, 650-950 nm), while the second NIR window (NIR-II, 1000-1700 nm) is far less exploited. The development of the first organic photothermal nanoagent (SPNI-II ) with dual-peak absorption in both NIR windows and its utilization in photothermal therapy (PTT) are reported herein. Such a nanoagent comprises a semiconducting copolymer with two distinct segments that respectively and identically absorb NIR light at 808 and 1064 nm. With the photothermal conversion efficiency of 43.4% at 1064 nm generally higher than other inorganic nanomaterials, SPNI-II enables superior deep-tissue heating at 1064 nm over that at 808 nm at their respective safety limits. Model deep-tissue cancer PTT at a tissue depth of 5 mm validates the enhanced antitumor effect of SPNI-II when shifting laser irradiation from the NIR-I to the NIR-II window. The good biodistribution and facile synthesis of SPNI II also allow it to be doped with an NIR dye for fluorescence-imaging-guided NIR II PTT through systemic administration. Thus, this study paves the way for the development of new polymeric nanomaterials to advance phototherapy. PMID- 29457285 TI - Vaginal isolation of beta-haemolytic Streptococcus from bitches with and without neonatal deaths in the litters. AB - The aim of the study was to identify beta-haemolytic streptococci in the vagina of bitches who had delivered healthy litters and bitches who had delivered litters in which neonatal deaths occurred. Fifty-one bitches divided into two groups were used. Group 1 (G1) included 28 bitches that had delivered healthy litters and group 2 (G2) included 23 bitches that had delivered puppies who died in the neonatal period. Two vaginal samples were taken, one in proestrus and the other at the end of gestation (EG). Beta-haemolytic Streptococcus (BS) was isolated from 16 bitches (57%) in G1 and from 21 bitches (91%) in G2. The bacteriological cultures, serological tests (Streptex(r) ) and PCR assay allowed identification of Streptococcus canis and Streptococcus dysgalactiae in G1 and G2. Ultramicroscopic studies allowed the observation of M Protein and capsules in strains of S. dysgalactiae and S. canis in G1 and G2. The S. canis strains isolated from G2 showed thicker capsules than S. canis strains isolated from G1 (234 +/- 24.2 vs 151.23 +/- 28.93 nm; p < .001.). No differences were observed in capsule thickness between strains of S. dysgalactiae isolated from G1 and G2 (210 +/- 13.54 vs 211.66 +/- 19.67 nm; p > .70). All strains of beta-haemolytic Streptococcus isolated were penicillin sensitive. Penicillin was administered from EG to 5 days post-partum in 10 G2 females with isolation of BS (G2A). Saline solution was administered in eleven G2 females with isolation of BS (G2B). Ninety per cent of the puppies survived in G2A and 25% survived in G2B. Our results suggest BS is involved in canine neonatal deaths. PMID- 29457286 TI - Applicability of low-flow atmospheric pressure chemical ionization and photoionization mass spectrometry with a microfabricated nebulizer for neutral lipids. AB - RATIONALE: Mass spectrometry with atmospheric pressure chemical ionization (APCI) or photoionization (APPI) is widely used for neutral lipids involved in many fundamental processes in living organisms. Commercial APCI and APPI sources operate at high flow rates compatible with conventional high-performance liquid chromatography (HPLC). However, lipid analysis is often limited by a small amount of sample, which requires low flow rate separations like capillary or micro-HPLC. Therefore, APCI and APPI suitable for microliter-per-minute flow rates need to be developed and applied for neutral lipids. METHODS: A micro-APCI/APPI source with a heated chip nebulizer was assembled and mounted on a Thermo ion trap instrument. The ion source operated in APCI, APPI or dual mode was optimized for low microliter-per-minute sample flow rates. The source performance was investigated for squalene, wax esters, fatty acid methyl esters, triacylglycerols, and cholesterol. RESULTS: The ion source behaved as a mass-flow sensitive detector. Direct infusion of methyl oleate showed superior analytical figures of merit when compared with high-flow ion sources. A detection limit of 200 pmol/mL and a linear dynamic range spanning three orders of magnitude were measured for micro-APCI. The mass spectra of most lipids differed from high flow rate spectra. Unlike micro-APCI, micro-APPI spectra were complicated by odd electron species. Dual APCI/APPI mode did not show any benefits for neutral lipids. Applications for lipid samples were demonstrated. CONCLUSIONS: Micro-APCI MS is a useful detection technique for neutral lipids at microliter-per-minute flow rates. It offers high sensitivity and high quality of spectra in direct infusion mode and promises successful utilization in capillary and micro-HPLC applications. PMID- 29457287 TI - Zero TE-based pseudo-CT image conversion in the head and its application in PET/MR attenuation correction and MR-guided radiation therapy planning. AB - PURPOSE: To describe a method for converting Zero TE (ZTE) MR images into X-ray attenuation information in the form of pseudo-CT images and demonstrate its performance for (1) attenuation correction (AC) in PET/MR and (2) dose planning in MR-guided radiation therapy planning (RTP). METHODS: Proton density-weighted ZTE images were acquired as input for MR-based pseudo-CT conversion, providing (1) efficient capture of short-lived bone signals, (2) flat soft-tissue contrast, and (3) fast and robust 3D MR imaging. After bias correction and normalization, the images were segmented into bone, soft-tissue, and air by means of thresholding and morphological refinements. Fixed Hounsfield replacement values were assigned for air (-1000 HU) and soft-tissue (+42 HU), whereas continuous linear mapping was used for bone. RESULTS: The obtained ZTE-derived pseudo-CT images accurately resembled the true CT images (i.e., Dice coefficient for bone overlap of 0.73 +/- 0.08 and mean absolute error of 123 +/- 25 HU evaluated over the whole head, including errors from residual registration mismatches in the neck and mouth regions). The linear bone mapping accounted for bone density variations. Averaged across five patients, ZTE-based AC demonstrated a PET error of -0.04 +/- 1.68% relative to CT-based AC. Similarly, for RTP assessed in eight patients, the absolute dose difference over the target volume was found to be 0.23 +/- 0.42%. CONCLUSION: The described method enables MR to pseudo-CT image conversion for the head in an accurate, robust, and fast manner without relying on anatomical prior knowledge. Potential applications include PET/MR-AC, and MR guided RTP. PMID- 29457288 TI - Injury to the perineal branch of the pudendal nerve in men: Outcomes from surgical resection of the perineal branches. AB - OBJECTIVE: The objective is to report the outcome of an anterior surgical approach to treat neuroma of the perineal branch of the pudendal nerve (PBPN). PATIENTS AND METHODS: An IRB-approved prospective study enrolled 14 consecutive male patients from 2011 through 2015 who had symptoms of perineal/scrotal pain. Each patient had a successful, diagnostic, pudendal nerve block. The surgical procedure was resection of the PBPN and implantation of the nerve into the obturator internus muscle. Mean age at surgery was 50 +/- 15 years. Median duration of pain symptoms was 5.5 years (range 1.2-42.9 years). Mechanisms of injury was exercise (6/14), prostatectomy (4/14), and falls (4/14). Outcomes were the Male Pudendal Pain Functional Questionnaire (MQ), and the Numeric Pain Rating Scale (NPRS). RESULTS: The mean postoperative follow-up was 26 +/- 14 months. The MQ demonstrated that after surgery, patients overall had significantly less disability due to pudendal pain (P < .03). The NPRS revealed that pain significantly improved (P < .004). CONCLUSIONS: Resection of the PBPN and implantation of this nerve into the obturator internus muscle significantly relieved men's pelvic pain disability. PMID- 29457289 TI - Noninvasively Modifying Band Structures of Wide-Bandgap Metal Oxides to Boost Photocatalytic Activity. AB - Although doping with appropriate heteroatoms is a powerful way of increasing visible light absorption of wide-bandgap metal oxide photocatalysts, the incorporation of heteroatoms into the photocatalysts usually leads to the increase of deleterious recombination centers of photogenerated charge carriers. Here, a conceptual strategy of increasing visible light absorption without causing additional recombination centers by constructing an ultrathin insulating heterolayer of amorphous boron oxynitride on wide-bandgap photocatalysts is shown. The nature of this strategy is that the active composition nitrogen in the heterolayer can noninvasively modify the electronic structure of metal oxides for visible light absorption through the interface contact between the heterolayer and metal oxides. The photocatalysts developed show significant improvements in photocatalytic activity under both UV-vis and visible light irradiation compared to the doped counterparts by conventional doping process. These results may provide opportunities for flexibly tailoring the electronic structure of metal oxides. PMID- 29457290 TI - Imaging Heterogeneously Distributed Photo-Active Traps in Perovskite Single Crystals. AB - Organic-inorganic halide perovskites (OIHPs) have demonstrated outstanding energy conversion efficiency in solar cells and light-emitting devices. In spite of intensive developments in both materials and devices, electronic traps and defects that significantly affect their device properties remain under investigated. Particularly, it remains challenging to identify and to resolve traps individually at the nanoscopic scale. Here, photo-active traps (PATs) are mapped over OIHP nanocrystal morphology of different crystallinity by means of correlative optical differential super-resolution localization microscopy (Delta SRLM) and electron microscopy. Stochastic and monolithic photoluminescence intermittency due to individual PATs is observed on monocrystalline and polycrystalline OIHP nanocrystals. Delta-SRLM reveals a heterogeneous PAT distribution across nanocrystals and determines the PAT density to be 1.3 * 1014 and 8 * 1013 cm-3 for polycrystalline and for monocrystalline nanocrystals, respectively. The higher PAT density in polycrystalline nanocrystals is likely related to an increased defect density. Moreover, monocrystalline nanocrystals that are prepared in an oxygen- and moisture-free environment show a similar PAT density as that prepared at ambient conditions, excluding oxygen or moisture as chief causes of PATs. Hence, it is concluded that the PATs come from inherent structural defects in the material, which suggests that the PAT density can be reduced by improving crystalline quality of the material. PMID- 29457291 TI - Does sedation offer better outcomes than local anaesthesia for thyroid FNA in adult patients? AB - OBJECTIVE: To examine the potential benefits of sedation in adults undergoing fine needle aspiration (FNA) of thyroid nodules. METHODS: This retrospective study compared the outcomes of sedated and non-sedated FNA patients. RESULTS: A total of 860 patients underwent 1698 FNAs of thyroid nodules. The mean patient age was 52.4+/-14.4 years, and 80.2% of patients were women. The non-sedated group consisted of 782 patients with 1543 (93.5%) FNA procedures. The sedated group consisted of 66 patients who underwent 107 (6.5%) FNAs. There was no statistical difference between these groups with respect to age, gender, nodule size, nodule vascularity, non-diagnostic sample rate and post FNA hematoma (P > .05). CONCLUSIONS: Performing FNA of thyroid nodules in adult patients under sedation is not associated with a higher diagnostic yield or lower bleeding rate when compared to local anesthesia. Sedation should be judiciously used on only very anxious patients due to the increased overall cost. PMID- 29457292 TI - Antibodies against H3 and H4 histones from the sera of HIV-infected patients catalyze site-specific degradation of these histones. AB - Histones and their posttranslational modified forms play pivotal roles in chromatin functioning and gene transcription. Also, histones are harmful when they enter the intercellular space; their administration to animals results in systemic inflammatory and toxic responses. Autoantibodies having enzymatic activities (abzymes) are the specific feature of several autoimmune and viral diseases. Electrophoretically homogeneous IgGs containing no canonical proteases were purified from sera of HIV-infected patients by using several affinity chromatographies. In contrast to known canonical proteases, Abs from HIV-infected patients hydrolyzed exclusively only histones but no other control globular proteins. The H3 and H4 histone cleavage sites by antihistone IgGs were determined by matrix-assisted laser desorption/ionization mass spectrometry for the first time. Two clusters of H3 hydrolysis contain major (?) and minor (*) cleavage sites: 18-K*Q*LA?TK*A?AR*KS?A*P-30 and 34-G*VK*KPHR*YRPGTVA*L*R-50. H4 histone has only 1 cluster of cleavage sites containing additionally moderate (?) cleavage sites: 15-A?KR?HR?KVLR?D*NIQ?GIT*K-31. Sites of these histones cleavage correspond mainly to their known epitopes. It was surprising that most of the cleavage sites of histones are involved in the interaction with DNA of nucleosome core. Because histones act as damage-associated molecules, abzymes against H3 and H4 can play important role in pathogenesis of AIDs and probably other viral and immune diseases. PMID- 29457293 TI - Ginsenoside Rh2 inhibits prostate cancer cell growth through suppression of microRNA-4295 that activates CDKN1A. AB - OBJECTIVES: Ginsenoside Rh2 (GRh2) has demonstrative therapeutic effects on a variety of diseases, including some tumours. However, the effects of GRh2 on prostate cancer (PC) cell growth remain unknown, and were, thus, addressed in the present study. MATERIALS AND METHODS: PC3 and DU145 PC cell lines were exposed to GRh2. Cell proliferation was assessed in an MTT assay and by BrdU incorporation. Apoptosis of the cells were assessed by TUNEL staining. Total RNA was assessed by RT-qPCR. Protein levels were assessed by Western blotting. Bioinformatics and dual luciferase reporter assay were applied to determine the functional binding of miRNA to mRNA of target gene. RESULTS: GRh2 dose-dependently decreased PC cell proliferation, but did not alter cell apoptosis. Mechanistically, GRh2 dose dependently increased the protein, but not mRNA of a cell-cycle suppressor CDKN1A in PC cells, suggesting the presence of microRNA (miRNA)-mediated protein translation control of CDKN1A by GRh2. In all candidate miRNAs that bind to 3' UTR of CDKN1A, miR-4295 was specifically found to be suppressed dose-dependently by GRh2 in PC cells. Moreover, miR-4295 bound CDKN1A to suppress its protein translation. Furthermore, cell proliferation in PC cells that overexpressed miR 4295 did not alter in response to GRh2. CONCLUSIONS: GRh2 may inhibit PC cell growth through suppression of microRNA-4295 that activates CDKN1A.

AB - There are approximately 350,000 young carers in Australia, yet their experience is not well understood. Young carers face adversities and disenfranchisement by being a young person in a caring role, and the role can affect other areas of their lives. We explored the lived experiences of young carers, aged 14-25 years (N = 13), from Western Australia through in-depth semi-structured interviews. A phenomenological approach was adopted. A thematic analysis of the transcribed interview data revealed four key themes. "Lessons from the experience" articulates the perceived benefits of the role and the themes: "navigating competing demands," "desire for normalcy" and "lost in the system" capture the struggles and complexities associated with being a young carer. Although there are challenges to being a young carer, it is something that young carers report can be beneficial and something that is done for those they love. PMID- 29457296 TI - Silk and Silk-Like Supramolecular Materials. AB - Silk is a source of marvel for centuries as one of nature's high-performance materials. More recently, chemical and structural analysis techniques have helped explore the relationship between silk's properties and its hierarchical structure. Furthermore, recombinant protein engineering as well as polymer and organic synthesis techniques have enabled the production of silk-like materials. It has become apparent that silk is a supramolecular polymer with many of the properties exhibited by well-known synthetic supramolecular materials, such as block copolymers, liquid crystals, thermoplastic elastomers, and self-assembling peptides. In this review, the hierarchical structure and supramolecular assembly of silk are discussed in comparison to these synthetic supramolecular systems. By focusing on the connections between chemical structure, nanoscale molecular organization, and material properties, the aim is to provide perspectives on the rational design of advanced soft matter to supramolecular chemists and molecular engineers who look to nature for inspiration. PMID- 29457297 TI - The impact of bacteriophages on phyllosphere bacterial abundance and composition. AB - Interactions between bacteria and bacteriophage viruses (phages) are known to influence pathogen growth and virulence, microbial diversity and even biogeochemical cycling. Lytic phages in particular infect and lyse their host cells, and can therefore have significant effects on cell densities as well as competitive dynamics within microbial communities. Despite the known impacts of lytic phages on the ecology and evolution of bacteria in free-living communities, little is known about the role of lytic phages in host-associated microbiomes. We set out to characterize the impact of phages in the tomato phyllosphere, that is the bacteria associated with above-ground plant tissues, by transferring microbial communities from field-grown tomato plants to juvenile plants grown under mostly sterile conditions in either the presence or absence of their associated phage community. In three separate experiments, we found that the presence of phages affects overall bacterial abundance during colonization of new host plants. Furthermore, bacterial community analysis using 16S rRNA amplicon sequencing shows that phages significantly alter the relative abundance of dominant community members and can influence both within- and among-host diversity. These results underscore the importance of lytic phages in host associated microbiomes and are relevant to microbiome transplantation approaches, as they suggest transferring nonbacterial components of the microbiome among hosts is likely to have a strong impact on growth of both the resident and colonizing microbiota. PMID- 29457298 TI - Forest structure provides the income for reproductive success in a southern population of Canada lynx. AB - Understanding intrinsic and extrinsic drivers of reproductive success is central to advancing animal ecology and characterizing critical habitat. Unfortunately, much of the work examining drivers of reproductive success is biased toward particular groups of organisms (e.g., colonial birds, large herbivores, capital breeders). Long-lived mammalian carnivores that are of conservation concern, solitary, and territorial present an excellent situation to examine intrinsic and extrinsic drivers of reproductive success, yet they have received little attention. Here, we used a Canada lynx (Lynx canadensis) data set, from the southern periphery of their range, to determine if reproductive success in a solitary carnivore was consistent with capital or income breeding. We radio marked and monitored 36 female Canada lynx for 98 lynx years. We evaluated how maternal characteristics and indices of food supply (via forest structure) in core areas influenced variation in body condition and reproductive success. We characterized body condition as mass/length and reproductive success as whether a female produced a litter of kittens for a given breeding season. Consistent with life-history theory, we documented a positive effect of maternal age on body condition and reproductive success. In contrast to predictions of capital breeding, we observed no effect of pre-pregnancy body condition on reproductive success in Canada lynx. However, we demonstrated statistical effects of forest structure on reproductive success in Canada lynx, consistent with predictions of income breeding. The forest characteristics that defined high success included (1) abundant and connected mature forest and (2) intermediate amounts of small diameter regenerating forest. These attributes are consistent with providing abundant, temporally stable, and accessible prey resources (i.e., snowshoe hares; Lepus americanus) for lynx and reinforce the bottom-up mechanisms influencing Canada lynx populations. Collectively, our results suggest that lynx on the southern range periphery exhibit an income breeding strategy and that forest structure supplies the income important for successful reproduction. More broadly, our insights advance the understanding of carnivore ecology and serve as an important example on integrating long-term field studies with ecological theory to improve landscape management.

AB - BACKGROUND: Clinical results of autologous osteochondral transplantation (AOT) for treatment of osteochondral lesions of the talus have been mixed. T1rho imaging can be used to noninvasively detect early cartilage degeneration. PURPOSE OR HYPOTHESIS: To quantitatively assess, by means of T1rho imaging, changes over time in the biochemical health of grafted cartilage after AOT for osteochondral lesions of the talus. STUDY TYPE: Retrosepctive case series. POPULATION: The study group comprised nine patients who underwent AOT for an osteochondral lesion of the talus and in whom T1rho mapping was performed 1 and 2 years postoperatively. FIELD STRENGTH/SEQUENCE: 3 Tesla. T1rho-weighted turbo field echo. ASSESSMENT: The mean T1rho value of full-thickness cartilage at the repair site and that of full-thickness cartilage elsewhere in the same image (far-field cartilage) were determined. Clinical assessment was based on the American Orthopaedic Foot & Ankle Society (AOFAS) scale. Correlation between the T1rho ratios (grafted-to-far-field cartilage T1rho values) and clinical outcomes was examined. STATISTICAL TESTS: Mixed effects model. Pearson correlation analysis. RESULTS: At 1 year, a significant difference existed between the mean T1rho value of the grafted cartilage (57.0 +/- 7.7 ms) and that of the far-field cartilage (41.8 +/- 4.6 ms) (P < 0.001). At 2 years, the mean T1rho value of the grafted cartilage (49.1 +/- 6.4 ms) was significantly lower than that at 1 year (P = 0.011). Moderate negative correlation was found between the 1-year T1rho ratio and 1-year AOFAS score (r = -0.60) and between the 2-year T1rho ratio and 2-year AOFAS score (r = -0.50). DATA CONCLUSION: Our observation of substantial restoration of the proteoglycan content of the grafted cartilage approximately 2 years after AOT for osteochondral lesions of the talus indicates that the content changes gradually and that the cartilage reparation process is slower than previously believed.

AB - A benzylic substitution of 3-indolyl(hydroxyl)acetate derivatives with thiols proceeded specifically in the presence of amino, carboxy, and phosphate groups in weakly acidic aqueous solutions under nearly physiological condition, while no reaction occurred at pH over 7. Kinetic studies revealed that the reaction followed second-order kinetics (first-order in the reactant and first-order in thiol) in contrast with the SN 1 mechanism of common benzylic substitution of alcohols. The utility of the present method for functionalization of biomacromolecules was demonstrated using several model proteins, such as lysozyme, insulin, trypsin, and serum albumin. The catalytic bioactivity of lysozyme in lysis of Micrococcus lysodeikticus cells was completely retained after the modification. PMID- 29457300 TI - Glucagon-like peptide 2 decreases osteoclasts by stimulating apoptosis dependent on nitric oxide synthase. AB - OBJECTIVES: Glucagon-like peptide 2 (GLP2) is involved in the regulation of energy absorption and metabolism. Despite the importance of the GLP2 signalling mechanisms on osteoclast, little has been studied on how GLP2 works during osteoclastogenesis. MATERIALS AND METHODS: RAW264.7 cells were infected with rLV Green-GLP2. The induction of osteoclasts was performed by RANKL. TRAP were detected by RT-PCR, Western blotting and staining. Total nitric oxide and total NOS activity were measured. Cells apoptosis was detected by Hoest33258 and Annix V staining. Animal test, chromatin immunoprecipitation (CHIP), co immunoprecipitation(IP) and luciferase reporter assay were also performed. RESULTS: We indicate that GLP2 is associated with osteoporosis-related factors in aged rats, including BALP, TRAP, IL6, TNFalpha, Nitric Oxide (NO), iNOS, calcitonin and occludin. Moreover, GLP2 is demonstrated to result in negative action during proliferation of tartrate-resistant acid phosphatase-positive (TRAP+) osteoclasts. Furthermore, GLP2 decreases osteoclasts induced from monocyte/macrophage cells RAW264.7 as well as the serum TRAP activity in aged rats. Mechanistic investigations reveal GLP2 enhances the expression of iNOS through stimulating the activity of TGFbeta-Smad2/3 signalling in osteoclasts. In particular, inhibition of TGFbeta fully abrogates this function of GLP2 in osteoclasts. Strikingly, overexpression of GLP2 significantly increases the product of nitric oxide via iNOS which promotes apoptosis of osteoclasts by decreasing bcl2 or increasing caspase3. Thereby, the ability of GLP2 to regulate apoptosis depends on TGFbeta-Smad2/3-iNOS-NO signalling pathway since total NOS inhibitor L-NMMA specifically inhibits the actions by GLP2. CONCLUSIONS: GLP2 induces apoptosis via TGFbeta-Smad2/3 signalling, which contributes to the inhibition of the proliferation of osteoclasts and which may provide potential therapeutic targets for the treatment of osteoporosis. PMID- 29457303 TI - Long term effects of ART: What do animals tell us? AB - Early stages of mammalian embryonic development are now known to be very sensitive to their microenvironment, with long term effects on fetal, postnatal, and adult health, thus extending to these early stages the concept of Developmental Origin of Health and Disease (DoHaD). In this scientific context, and with 3% of births in developed countries, safety of Assisted Reproductive Techniques procedures becomes a matter of concern. Besides, embryo technologies in domestic mammals, using huge number of embryos, do not seem to evidence heavy impacts on adult phenotypes. This paper first discusses what can or cannot be concluded from farm animal data, then develops long term effects of ART procedures (ovarian stimulation, in vitro fertilization and embryo culture) evidenced in model species (mainly mouse model). Recent literature demonstrates both individual and cumulative effects of each ART procedure on fetal and postnatal phenotypes. In a second part, because they are sources for further perturbations, immediate effects of ART on early embryo phenotypes at the cellular and molecular levels are described in both farm animals and model species. Mechanistic hypotheses supporting these ART induced phenotypic alterations are subsequently considered. Finally, taking into account interspecies differences in the mechanisms likely to be involved, the relevance of results obtained in animal models for human ART are discussed. PMID- 29457304 TI - 'Everyone has an agenda': Professionals' understanding and negotiation of risk within the Guardianship system of Victoria, Australia. AB - It is frequently asserted that pressures to assess and manage risk have eroded the therapeutic, rights-based foundation of the human services profession. Some argue that human service workers operate in a culture of fear in which self protection and blame avoidance, rather than clients' needs, primarily drive decision-making. In the field of Adult Guardianship, it has been suggested that organisational risk avoidance may be motivating applications for substitute decision-makers, unnecessarily curtailing clients' rights and freedoms. However, the absence of research examining the operation of risk within Guardianship decision-making inhibits verifying and responding to this very serious suggestion. This article draws on semi-structured interviews conducted with 10 professionals involved in the Victorian Guardianship system, which explored how issues of risk are perceived and negotiated in everyday practice. Risk was found to be a complex and subjective construct which can present both dangers and opportunities for Guardianship practitioners and their clients. While a number of participants reported that Guardianship might sometimes operate as an avenue for mitigating the fear and uncertainty of risk, most participants also valued positive risk-taking and were willing, in their clients' interests, to challenge conservative logics of risk. These findings highlight the need for further research which examines how service providers and policy makers can create spaces that support open discussions around issues of risk and address practitioners' sense of fear and vulnerability. PMID- 29457302 TI - Innate lymphoid cells at the human maternal-fetal interface in spontaneous preterm labor. AB - PROBLEM: Pathological inflammation is causally linked to preterm labor and birth, the leading cause of neonatal morbidity and mortality worldwide. Our aims were to investigate whether (i) the newly described family of innate lymphoid cells (ILCs) was present at the human maternal-fetal interface and (ii) ILC inflammatory subsets were associated with the pathological process of preterm labor. METHODS OF STUDY: Decidual leukocytes were isolated from women with preterm or term labor as well as from gestational age-matched non-labor controls. ILCs (CD15- CD14- CD3- CD19- CD56- CD11b- CD127+ cells) and their subsets (ILC1, T-bet+ ILCs; ILC2, GATA3+ ILCs; and ILC3, RORgammat+ ILCs) and cytokine expression were identified in the decidual tissues using immunophenotyping. RESULTS: (i) The proportion of total ILCs was increased in the decidua parietalis of women with preterm labor; (ii) ILC1s were a minor subset of decidual ILCs during preterm and term gestations; (iii) ILC2s were the most abundant ILC subset in the decidua during preterm and term gestations; (iv) the proportion of ILC2s was increased in the decidua basalis of women with preterm labor; (v) the proportion of ILC3s was increased in the decidua parietalis of women with preterm labor; and (vi) during preterm labor, ILC3s had higher expression of IL-22, IL 17A, IL-13, and IFN-gamma compared to ILC2s in the decidua. CONCLUSION: ILC2s were the most abundant ILC subset at the human maternal-fetal interface during preterm and term gestations. Yet, during preterm labor, an increase in ILC2s and ILC3s was observed in the decidua basalis and decidua parietalis, respectively. These findings provide evidence demonstrating a role for ILCs at the maternal fetal interface during the pathological process of preterm labor. PMID- 29457305 TI - Light-Induced Reversible Control of Ferroelectric Polarization in BiFeO3. AB - Manipulation of ferroic order parameters, namely (anti-)ferromagnetic, ferroelectric, and ferroelastic, by light at room temperature is a fascinating topic in modern solid-state physics due to potential cross-fertilization in research fields that are largely decoupled. Here, full optical control, that is, reversible switching, of the ferroelectric/ferroelastic domains in BiFeO3 thin films at room temperature by the mediation of the tip-enhanced photovoltaic effect is demonstrated. The enhanced short-circuit photocurrent density at the tip contact area generates a local electric field well exceeding the coercive field, enabling ferroelectric polarization switching. Interestingly, by tailoring the photocurrent direction, via either tuning the illumination geometry or simply rotating the light polarization, full control of the ferroelectric polarization is achieved. The finding offers a new insight into the interactions between light and ferroic orders, enabling fully optical control of all the ferroic orders at room temperature and providing guidance to design novel optoferroic devices for data storage and sensing. PMID- 29457306 TI - Functional characterization of collaterals in the human gingiva by laser speckle contrast imaging. AB - OBJECTIVE: The rate of blood flow between the various areas of the gingiva in resting position and under challenge is unknown. In this study, the LSCI method was used to map spatial and temporal changes in gingival blood flow after transient compression. METHODS: Horizontal, vertical, and papilla base compressions were applied on the attached gingiva in 21 healthy patients (13 women, 8 men). LSCI was used to determine dynamic changes in regional blood flow during a five-second occlusion interval and subsequent reperfusion for twenty minutes. RESULTS: Resting blood flow in the attached gingiva apical to the papillae was higher as compared to that in the midbuccal area of the teeth. During short-term horizontal compression, ischemia was greater coronal than apical to the occlusion line. Postocclusive hyperemia was observed not only in the regions affected by ischemia but encompassed a wider area. Hyperemic response was more pronounced and prolonged in male than in female patients. CONCLUSIONS: Blood flow in the attached gingiva shows spatial differences. Our findings corroborate the apicocoronal orientation of blood circulation. Periodontal and papillary collaterals may have little role in the blood supply of the adjacent attached gingiva under physiological conditions. PMID- 29457307 TI - Iron and infection: An investigation of the optimal iron hypothesis in Lima, Peru. AB - OBJECTIVES: This article explores the optimal iron hypothesis through secondary data analysis of the association between hemoglobin levels and morbidity among children living in Canto Grande, a peri-urban community located on the outskirts of Lima, Peru. METHODS: Risk ratios were used to test whether lower iron status, assessed using the HemoCue B-Hemoglobin System, was associated with an increased relative risk of morbidity symptoms compared to iron replete status, controlling for infant age, sex, weight for height z-score, maternal education, and repeated measures in 515 infants aged 6-12 months. RESULTS: Infants with fewer current respiratory and diarrheal morbidity symptoms had a lower risk of low iron deficiency compared to participants who were iron replete (P < .10). Infants with fewer current respiratory infection symptoms had a statistically significant (P < .05) reduction in risk of moderate iron deficiency compared to infants who were iron replete. CONCLUSION: In this study, morbidity status was not predictive of iron deficient status over a six-month interval period, but nonreplete iron status was shown to be associated with current morbidity symptoms. These results support investigating iron status as an allostatic system that responds to infection adaptively, rather than expecting an optimal preinfection value. PMID- 29457308 TI - Single Carbon Fibers with a Macroscopic-Thickness, 3D Highly Porous Carbon Nanotube Coating. AB - Carbon fiber (CF) grafted with a layer of carbon nanotubes (CNTs) plays an important role in composite materials and other fields; to date, the applications of CNTs@CF multiscale fibers are severely hindered by the limited amount of CNTs grafted on individual CFs and the weak interfacial binding force. Here, monolithic CNTs@CF fibers consisting of a 3D highly porous CNT sponge layer with macroscopic-thickness (up to several millimeters), which is directly grown on a single CF, are fabricated. Mechanical tests reveal high sponge-CF interfacial strength owing to the presence of a thin transitional layer, which completely inhibits the CF slippage from the matrix upon fracture in CNTs@CF fiber-epoxy composites. The porous conductive CNTs@CF hybrid fibers also act as a template for introducing active materials (pseudopolymers and oxides), and a solid-state fiber-shaped supercapacitor and a fiber-type lithium-ion battery with high performances are demonstrated. These CNTs@CF fibers with macroscopic CNT layer thickness have many potential applications in areas such as hierarchically reinforced composites and flexible energy-storage textiles. PMID- 29457309 TI - Severe intestinal malabsorption associated with ACE inhibitor or angiotensin receptor blocker treatment. An observational cohort study in Germany and Italy. AB - PURPOSE: The angiotensin II receptor blocker (ARB) olmesartan has been recently associated with sprue-like enteropathy (SLE), a gastrointestinal condition characterized by intestinal malabsorption (IM) and severe diarrhea. Whether the increased risk of SLE is substance-specific or a class effect involving all ARBs is uncertain. The aim of this study is to assess the risk of enteropathy associated with ARBs and angiotensin converting enzyme inhibitors (ACE-i) by using data from large administrative and claim databases. METHODS: We obtained data from Italian local health-care units and a large German claim database and included patients treated with olmesartan, other ARBs, and ACE-i. In the absence of a specific diagnosis code for SLE, International Classification of Diseases codes for IM were used. Analysis implemented a Poisson regression with robust error variance procedure, which allowed accounting for different clusters (local health-care units and countries) and correctly estimating the standard error for the relative risk of rare event occurrence. RESULTS: Patients were divided into 3 groups: olmesartan (25.591, 5.5%), other ARBs (104.901, 22.5%), and ACE-i patients (334.951, 72.0%). Baseline characteristics were similar overall. The incidence of unspecified IM in ACE-i patients was not different compared with that of olmesartan, whereas a higher rate ratio was observed when comparing ARB patients with the olmesartan group (RR: 2.50, 95% CI 1.21 to 5.19, P .01). When International Classification of Diseases codes for coeliac disease were included, no differences were observed. CONCLUSIONS: We could not confirm previous findings of a higher risk of malabsorption in olmesartan-only patients, and drug-induced enteropathy should be considered the result of exposure to the class of ARBs rather than a specific drug-related effect. PMID- 29457311 TI - Bicuspid Axial Wall Height Effect on CAD/CAM Crown Fracture Mode on Preparations Containing Advanced Total Occlusal Convergence. AB - PURPOSE: To evaluate bicuspid axial wall height effect on the fracture mode of adhesively luted, all-ceramic CAD/CAM crowns with a 20 degrees total occlusal convergence (TOC). MATERIALS AND METHODS: Recently extracted premolars were randomly divided into 4 groups (n = 12) with all-ceramic crown preparations accomplished using a high-speed handpiece inserted into a milling device. Specimens were prepared containing occlusogingival axial wall heights of 3, 2, and 1 mm as well as a group containing a flat preparation surface with no axial wall height. All preparations contained a 20 degrees TOC. Completed preparation surface area was determined, and preparation features confirmed using a digital measuring microscope. Scanned preparations (CEREC) were fitted with milled and crystallized lithium disilicate full coverage restorations and luted with a self etching adhesive resin cement after hydrofluoric acid etching and silanation. All manufacturer recommendations were followed. Specimens were stored at 37 degrees C/98% humidity for 24 hours. Specimens were tested to failure at a 45 degrees angle to the long axis of the tooth root on a universal testing machine. Failure load was converted to MPa using the available bonding surface area with mean data analyzed using Kruskal-Wallis/Dunn's (p = 0.05) RESULTS: The 3 mm preparation height specimens were similar to the 2 mm specimens, and both demonstrated significantly stronger failure load than the 1 mm axial wall height and flat preparation specimens. The flat preparation and 1 mm axial wall height specimens all failed adhesively, while the 2 mm and 3 mm specimens failed largely due to tooth fracture. CONCLUSIONS: Further evidence is provided that CAD/CAM adhesive techniques may compensate for less than ideal preparation features. Under the conditions of this study, bicuspid preparations with a 20 degrees TOC restored with adhesively luted, CAD/CAM e.max CAD crowns require at least 2 mm of axial wall height, but further planned fatigue studies are necessary before definitive recommendations can be made. PMID- 29457310 TI - Natural fruits, flowers, honey, and honeybees harbor Helicobacter pylori-positive yeasts. AB - BACKGROUND: For controlling Helicobacter pylori infection in humans, its environmental reservoir should be determined. In this study, yeast isolates from an isolated village in Iran were studied for the intracellular occurrence of H. pylori. MATERIALS AND METHODS: In this study, yeasts were isolated from 29 samples, including oral swabs from villagers (n = 7), flowers and fruits (n = 6), honey and honeybees (n = 12) and miscellaneous samples (4). Yeasts were classified into 12 RFLP groups and identified by amplification of 26S rDNA and sequencing. DNA extracted from the yeast cells was examined for the presence of H. pylori using PCR. RESULTS: Of the 29 yeasts, 27 were members of different genera of Ascomycete. H. pylori was detected in 5 of 9 Candida (55.5%), 4 of 5 Komagataella (80%), 3 of 4 Pichia (100%), 2 of 2 Cytobasidia (100%), 2 of 2 Hansenia (100%), 1 of 1 Meyerozyma (100%) and 2 of 3 not sequenced (66.6%) yeasts. Distribution of 19 of 29 (65.5%) H. pylori-positive yeasts within 4 groups was as follows: 1 of 7(14.3%) in oral swabs, 5 of 6 (83.3%) in flowers and fruits, 10 of 12 (83.3%) in honey and the bee group and 3 of 4 (75%) in miscellaneous. CONCLUSIONS: Different genera of osmotolerant yeasts from flowers, fruits, honey, and honeybees contained H. pylori in their vacuole. High frequency of H. pylori-positive yeasts in these samples might be related to their high sugar content. Insects such as honeybees that facilitate transfer and easy access of these yeasts to nectars serve as the main reservoirs of these yeasts, playing an important role in their protection and dispersal. Accordingly, H. pylori inside these yeasts can be carried by honeybees to different sugar- and nutrient rich environments. Sugar-rich environments and honeybees play an important role in distribution of H. pylori-positive yeasts in nature. PMID- 29457312 TI - Update on tuberculosis biomarkers: From correlates of risk, to correlates of active disease and of cure from disease. AB - Tuberculosis (TB) remains a devastating disease, yet despite its enormous toll on global health, tools to control TB are insufficient and often outdated. TB Biomarkers (TB-BM) would constitute extremely useful tools to measure infection status and predict outcome of infection, vaccination or therapy. There are several types of TB-BM: Correlate of Infection; Correlate of TB Disease; Correlate of Increased Risk of Developing Active TB Disease; Correlate of the Curative Response to Therapy; and Correlate of Protection (CoP). Most TB-BM currently studied are host-derived BM, and consist of transcriptomic, proteomic, metabolomic, cellular markers or marker combinations ('signatures'). In particular, vaccine-inducible CoP are expected to be transformative in developing new TB vaccines as they will de-risk vaccine research and development (R&D) as well as human testing at an early stage. In addition, CoP could also help minimizing the need for preclinical studies in experimental animals. Of key importance is that TB-BM are tested and validated in different well-characterized human TB cohorts, preferably with complementary profiles and geographically diverse populations: genetic and environmental factors such as (viral) coinfections, exposure to non-tuberculous mycobacteria, nutritional status, metabolic status, age (infants vs children vs adolescents vs adults) and other factors impact host immune set points and host responses across different populations. In this study, we review the most recent advances in research into TB-BM for the diagnosis of active TB, risk of TB development and treatment induced TB cure. PMID- 29457313 TI - Modeling the hematocrit distribution in microcirculatory networks: A quantitative evaluation of a phase separation model. AB - OBJECTIVE: Theoretical models are essential tools for studying microcirculatory function. Recently, the validity of a well-established phase separation model was questioned and it was claimed that it produces problematically low hematocrit predictions and lack of red cells in small diameter vessels. We conducted a quantitative evaluation of this phase separation model to establish common ground for future research. METHODS: Model predictions were validated against a comprehensive database with measurements from 4 mesenteric networks. A Bayesian data analysis framework was used to integrate measurements and network model simulations into a combined analysis and to model uncertainties related to network boundary conditions as well as phase separation model parameters. The model evaluation was conducted within a cross-validation scheme. RESULTS: Unlike the recently reported results, our analysis demonstrated good correspondence in global characteristics between measurements and predictions. In particular, predicted hematocrits for vessels with small diameters were consistent with measurements. Incorporating phase separation model parameter uncertainties further reduced the hematocrit validation error by 17% and led to the absence of red-cell-free segments. Corresponding model parameters are presented as alternatives to standard parameters. CONCLUSIONS: Consistent with earlier studies, our quantitative model evaluation supports the continued use of the established phase separation model. PMID- 29457314 TI - Latent source mining in FMRI via restricted Boltzmann machine. AB - Blind source separation (BSS) is commonly used in functional magnetic resonance imaging (fMRI) data analysis. Recently, BSS models based on restricted Boltzmann machine (RBM), one of the building blocks of deep learning models, have been shown to improve brain network identification compared to conventional single matrix factorization models such as independent component analysis (ICA). These models, however, trained RBM on fMRI volumes, and are hence challenged by model complexity and limited training set. In this article, we propose to apply RBM to fMRI time courses instead of volumes for BSS. The proposed method not only interprets fMRI time courses explicitly to take advantages of deep learning models in latent feature learning but also substantially reduces model complexity and increases the scale of training set to improve training efficiency. Our experimental results based on Human Connectome Project (HCP) datasets demonstrated the superiority of the proposed method over ICA and the one that applied RBM to fMRI volumes in identifying task-related components, resulted in more accurate and specific representations of task-related activations. Moreover, our method separated out components representing intermixed effects between task events, which could reflect inherent interactions among functionally connected brain regions. Our study demonstrates the value of RBM in mining complex structures embedded in large-scale fMRI data and its potential as a building block for deeper models in fMRI data analysis. PMID- 29457315 TI - Testing the validity and reliability of the Self-Administration of Medication (SAM) instrument in Chinese chronic disease patients: A cross-cultural adaptation. AB - AIMS: To develop a culturally appropriate and functional standard Mandarin Chinese translation of the Self-Administration of Medication tool and to examine its validity and reliability. METHODS: We used Brislin's guidelines for the translation and back-translation procedures. We recruited 130 patients from June 2015 to September 2016. Correlation analysis, Cronbach's alpha coefficient, split half reliability, item analysis and the content validity index, and exploratory factor analysis were performed. RESULTS: Strong and moderate correlations were seen between the total Self-Administration of Medication score and nurses' and patients' perceptions. Item analysis indicated that the correlation coefficient ranged from 0.744 to 0.975. Cronbach's alpha ranged from 0.933 to 0.976. The split-half reliability ranged from 0.911 to 0.936 for the instrument's subscales, and 0.953 for the total scale. The content validity index value ranged from 0.823 to 0.972 for individual items and was 0.968 for the total scale. The factor loading matrix of the SAM ranged from 0.514 to 0.837. A moderate correlation existed between the scores of the Self-Administration of Medication tool and the Barthel Index. CONCLUSION: The Chinese version of the Self-Administration of Medication tool is statistically acceptable and can be used in the evaluation of self-medication ability based on self-report and nurses' assessment. PMID- 29457317 TI - Effects of alcohol intoxication on self-reported drinking patterns, expectancies, motives and personality: a randomized controlled experimental study. AB - Alcohol intoxication may affect self-reports of alcohol use and related constructs, such as impulsivity and dependence symptoms. Improved knowledge about potential systematic reporting biases induced by alcohol, e.g. through disinhibition, may be relevant for the assessment of intoxicated individuals both in clinical routine and research. We therefore randomly assigned 54 socially drinking males aged 18 to 19 without lifetime diagnosis of DSM-IV alcohol dependence to one of two experimental arms: either placebo infusion at day 1 and alcohol infusion at day 2, or vice versa. The lab-based intravenous alcohol infusion produced a constant blood alcohol level of 0.08 percent. On each day, participants completed the Alcohol Use Disorders Identification Test, as well as other questionnaires on alcohol expectancies, drinking motives and substance use related temperament traits. We found that alcohol significantly increased self reported expectancies (tension reduction) and motives (conformity; eta2 = .16 .23), but we observed no effect of sequence, i.e. alcohol first versus placebo first (Pcorr >= .118). High baseline alcohol expectancies did not moderate alcohol effects (Pcorr >= .462). We conclude that moderate alcohol intoxication might not generally affect the reliability of self-reported alcohol use, alcohol use problems and psychological concepts related to drinking behavior in young males without alcohol dependence. Future studies could examine larger, less selective and clinical samples for possible alcohol effects on self-report measures related to alcohol consumption. PMID- 29457316 TI - Assessment of pulmonary structure-function relationships in young children and adolescents with cystic fibrosis by multivolume proton-MRI and CT. AB - BACKGROUND: Lung disease is the most frequent cause of morbidity and mortality in patients with cystic fibrosis (CF), and there is a shortage of sensitive biomarkers able to regionally monitor disease progression and to assess early responses to therapy. PURPOSE: To determine the feasibility of noncontrast enhanced multivolume MRI, which assesses intensity changes between expiratory and inspiratory breath-hold images, to detect and quantify regional ventilation abnormalities in CF lung disease, with a focus on the structure-function relationship. STUDY TYPE: Retrospective. POPULATION: Twenty-nine subjects, including healthy young children (n = 9, 7-37 months), healthy adolescents (n = 4, 14-22 years), young children with CF lung disease (n = 10, 7-47 months), and adolescents with CF lung disease (n = 6, 8-18 years) were studied. FIELD STRENGTH/SEQUENCE: 3D spoiled gradient-recalled sequence at 1.5T. ASSESSMENT: Subjects were scanned during breath-hold at functional residual capacity (FRC) and total lung capacity (TLC) through noncontrast-enhanced MRI and CT. Expiratory inspiratory differences in MR signal-intensity (Delta1 H-MRI) and CT-density (DeltaHU) were computed to estimate regional ventilation. MR and CT images were also evaluated using a CF-specific scoring system. STATISTICAL TESTS: Quadratic regression, Spearman's correlation, one-way analysis of variance (ANOVA). RESULTS: Delta1 H-MRI maps were sensitive to ventilation heterogeneity related to gravity dependence in healthy lung and to ventilation impairment in CF lung disease. A high correlation was found between MRI and CT ventilation maps (R2 = 0.79, P < 0.001). Globally, Delta1 H-MRI and DeltaHU decrease with increasing morphological score (respectively, R2 = 0.56, P < 0.001 and R2 = 0.31, P < 0.001). Locally, Delta1 H-MRI was higher in healthy regions (median 15%) compared to regions with bronchiectasis, air trapping, consolidation, and to segments fed by airways with bronchial wall thickening (P < 0.001). DATA CONCLUSION: Multivolume noncontrast-enhanced MRI, as a nonionizing imaging modality that can be used on nearly any MRI scanner without specialized equipment or gaseous tracers, may be particularly valuable in CF care, providing a new imaging biomarker to detect early alterations in regional lung structure-function.

PMID- 29457318 TI - Equity dimensions of the availability and quality of reproductive, maternal and neonatal health services in Zambia. AB - OBJECTIVE: To assess how quality and availability of reproductive, maternal, neonatal (RMNH) services vary by district wealth and urban/rural status in Zambia. METHODS: We conducted a retrospective analysis of data from the Millennium Development Goal Acceleration Initiative baseline assessment of 117 health facilities in 9 districts. Quality was assessed through a composite score of 23 individual RMNH indicators, ranging from 0 to 1. Availability was evaluated by density of providers and facilities. Districts were divided into wealth groups based on the multidimensional poverty index (MPI). Relative inequity was calculated using the concentration index for quality indicators (positive favours rich, negative favours poor). Multivariable linear regression was performed for the dependent variable composite quality indicator using MPI, urban/rural, and facility level of care as independent variables. RESULTS: 13 hospitals, 85 health centres and 19 health posts were included. The RMNH composite quality indicator was 0.64. Availability of facilities and providers was universally low. The concentration index for the composite quality indicator was -0.015 [-0.043, 0.013], suggesting no clustering to favour either rich or poor districts. Rich districts had the highest absolute numbers of health facilities and providers, but lowest numbers per facility per 1 000 000 population. Urban districts had slightly better service quality, but not availability. Using regression analysis, only facility level of care was significantly associated with quality outcome. CONCLUSIONS: Composite quality of RMNH services did not vary by district wealth, but was slightly higher in urban districts. The availability data suggest that the higher population in richer districts outpaces health infrastructure.

AB - Squamous cell carcinoma (SCC) of the head and neck can be treated with a combination of modalities. There is an esthetic and functional compromise with midfacial defects secondary to ablative surgery and adjuvant therapies for SCC. Osteoradionecrosis, tissue contracture, and trismus, are all negative side effects of treatment and can impact a patient's function and possibly their nutrition. In this report, we describe a procedure for fabrication of a prosthesis that provides cosmetic improvement and labial competence to maintain caloric intake. PMID- 29457319 TI - The impact of B1+ correction on MP2RAGE cortical T1 and apparent cortical thickness at 7T. AB - Determination of cortical thickness using MRI has often been criticized due to the presence of various error sources. Specifically, anatomical MRI relying on T1 contrast may be unreliable due to spatially variable image contrast between gray matter (GM), white matter (WM) and cerebrospinal fluid (CSF). Especially at ultra high field (>= 7T) MRI, transmit and receive B1 -related image inhomogeneities can hamper correct classification of tissue types. In the current paper, we demonstrate that residual B1+ (transmit) inhomogeneities in the T1 -weighted and quantitative T1 images using the MP2RAGE sequence at 7T lead to biases in cortical thickness measurements. As expected, post-hoc correction for the spatially varying B1+ profile reduced the apparent T1 values across the cortex in regions with low B1+, and slightly increased apparent T1 in regions with high B1+. As a result, improved contrast-to-noise ratio both at the GM-CSF and GM-WM boundaries can be observed leading to more accurate surface reconstructions and cortical thickness estimates. Overall, the changes in cortical thickness ranged between a 5% decrease to a 70% increase after B1+ correction, reducing the variance of cortical thickness values across the brain dramatically and increasing the comparability with normative data. More specifically, the cortical thickness estimates increased in regions characterized by a strong decrease of apparent T1 after B1+ correction in regions with low B1+ due to improved detection of the pial surface. The current results suggest that cortical thickness can be more accurately determined using MP2RAGE data at 7T if B1+ inhomogeneities are accounted for.

AB - AIMS: Twenty-five enological yeasts belonging to nine different species (Candida zeylanoides, Cryptococcus uzbekistanensis, Debaryomyces hansenii, Lachancea thermotolerans, Metschnikowia pulcherrima, Torulaspora delbrueckii, Williopsis pratensis, Zygosaccharomyces bailii and Saccharomyces cerevisiae) were screened for aroma formation and fermentative behaviour as part of a non-Saccharomyces yeast selection programme. METHODS AND RESULTS: Pure cultures were inoculated in pasteurized grape juice in order to perform alcoholic fermentations. Some non Saccharomyces species did not ferment, others did not get established and none of them completed alcoholic fermentations. The physico-chemical parameters of the wines and the abundance of aromatic compounds at the end of alcoholic fermentation highlighted the notable differences in the aroma-forming ability and fermentative behaviour of the different non-Saccharomyces species, but not within clones. CONCLUSIONS: Lower diversity was detected within non-Saccharomyces species than that reported in S. cerevisiae with regard to enological behaviour and aromatic profiles. Metschnikowia pulcherrima and L. thermotolerans are the two species with higher possibilities to become an inoculum. SIGNIFICANCE AND IMPACT OF THE STUDY: Few significant differences were found within clones of the same species, but very important parameters in wine quality, such as volatile acidity, ethyl acetate and acetoin, which would justify selection programmes within those species. The results also demonstrated that T. delbrueckii and L. thermotolerans are two close species in their aromatic profiles.

PMID- 29457323 TI - Anticoagulation knowledge in patients with atrial fibrillation: An Australian survey. AB - BACKGROUND: Atrial fibrillation (AF) is the most commonly diagnosed arrhythmia in clinical practice, and is associated with a significant medical and economic burden. Anticoagulants reduce the risk of stroke and systemic embolism by approximately two-thirds compared with no therapy. Knowledge regarding anticoagulant therapy can influence treatment outcomes in patients with AF. OBJECTIVE: To measure the level of anticoagulation knowledge in patients with AF taking oral anticoagulants (OACs), investigate the association between patient related factors and anticoagulation knowledge, and compare these results in patients taking warfarin and direct-acting oral anticoagulant (DOACs). METHODS: Participants were recruited for an online survey via Facebook. Survey components included the Anticoagulation Knowledge Tool, the Perception of Anticoagulant Treatment Questionnaires (assessing treatment expectations, convenience and satisfaction), a modified Cancer Information Overload scale and the Morisky Medication Adherence Scale. Treatment groups were compared and predictors of OAC knowledge were identified. RESULTS: Participants taking warfarin had a higher knowledge score compared with those taking DOACs (n = 386, 73% +/- 13% vs 66% +/- 14%, P<.001). Advancing age, type of OAC, health information overload and ease of OAC use (treatment expectation) were significant predictors of knowledge. Treatment expectation, including the belief that OAC treatment would cause bleeding side effects, varied significantly between participants taking warfarin and DOACs (P = .011). CONCLUSION: The study identified knowledge gaps in patients taking OACs, and these deficiencies appeared to be greater in participants taking DOACs. Knowledge assessment should be integrated into patient counselling sessions to help identify and resolve knowledge deficits. PMID- 29457324 TI - Investigation of the language tasks to include in a short-language measure for children in the early school years. AB - BACKGROUND: The inaccurate estimation of language difficulties by teachers suggests the benefit of a short-language measure that could be used to support their decisions about who requires referral to a speech-language therapist. While the literature indicates the potential for the development of a short-language measure, evidence is lacking about which combination of language tasks it should include. AIMS: To understand the number and nature of components/language tasks that should be included in a short-language measure for children in the early school years. METHODS & PROCEDURES: Eight language tasks were administered to participants of the Early Language in Victoria Study (ELVS) at ages 5 (n = 995) and 7 (n = 1217). These included six language tasks measured by an omnibus language measure (which comprised a direction-following, morphological completion, sentence-recall, sentence-formation, syntactic-understanding and word association task) and a non-word repetition and a receptive vocabulary task, measured by two task-specific language measures. Scores were analyzed using principal component analysis (PCA), the Bland and Altman method, and receiver operating characteristic (ROC) curve analysis. OUTCOMES & RESULTS: PCA revealed one main component of language that was assessed by all language tasks. The most effective combination of two tasks that measured this component was a direction following and a sentence-recall task. It showed the greatest agreement with an omnibus language measure and exceeded the criterion for good discriminant accuracy (sensitivity = 94%, specificity = 91%, accuracy = 91%, at 1 SD (standard deviation) below the mean). CONCLUSIONS & IMPLICATIONS: Findings support the combination of a direction-following and a sentence-recall task to assess language ability effectively in the early school years. The results could justify the future production of a novel short-language measure comprising a direction following and a sentence-recall task to use as a screening tool in schools and to assess language ability in research participants.

AB - Weak intermolecular interaction in organic semiconducting molecular crystals plays an important role in molecular packing and electronic properties. Here, four five-ring-fused isomers were rationally designed and synthesized to investigate the isomeric influence of linear and angular shapes in affecting their molecular packing and resultant electronic properties. Single-crystal field effect transistors showed mobility order of 5,7-ICZ (3.61 cm2 V-1 s-1 ) >5,11 ICZ (0.55 cm2 V-1 s-1 ) >11,12-ICZ (ca. 10-5 cm2 V-1 s-1 ) and 5,12-ICZ (ca. 10-6 cm2 V-1 s-1 ). Theoretical calculations based on density functional theory (DFT) and polaron transport model revealed that 5,7-ICZ can reach higher mobilities than the others thanks to relatively higher hole transfer integral that links to stronger intermolecular interaction due to the presence of multiple NH???pi and CH???pi(py) interactions with energy close to common NH???N hydrogen bonds, as well as overall lower hole-vibrational coupling owing to the absence of coupling of holes to low frequency modes due to better pi conjugation. PMID- 29457326 TI - Associations between adolescent risk for restrictive disordered eating and long term outcomes related to somatic symptoms, body mass index, and poor well-being. AB - OBJECTIVE: To date, no longitudinal, community-based studies have examined the association between disordered eating emerging in adolescence and long-term physical well-being. This study sought to explore the longitudinal associations between risk for restrictive disordered eating (DE-R; those not presenting with binge-purge symptoms) in adolescence and trajectories of functional somatic symptoms (FSS) and body mass index (BMI), and several indicators of poor physical well-being across early- to mid-adulthood, including medication, number of doctor visits, and sick leave. DESIGN: Data were obtained from the Northern Swedish Cohort Study (N = 1,001), a prospective longitudinal study including four time points from age 16 to 42 years. METHODS: A cumulative measure of DE-R risk was computed. Latent class growth analysis was used to identify subpopulation trajectories of FSS and BMI. The three-step method for auxiliary variables and logistic regressions were used to assess associations between DE-R and the trajectory classes as well as indicators of poor physical well-being. RESULTS: Three trajectories were identified for FSS. A gender by BMI interaction led to a classification of four BMI trajectories in men, but three in women. The presence of DE-R risk in adolescence increased odds of unfavourable FSS development, increasing BMI in women, and continually low BMI in men. Indicators of poor physical well-being at ages 21, 30, and 42 years were associated with DE-R risk in adolescence. CONCLUSIONS: Data spanning nearly three decades suggest that physical well-being impairment is related to DE-R risk measured earlier in life, underscoring the urgency for targeted, gender-sensitive preventive interventions for teenagers. Statement of contribution What is already known on this subject? Disordered eating is linked to poor physical and mental well-being and quality of life. No longitudinal studies have examined long-term physical well-being consequences of adolescent disordered eating risk. What does this study add? Non purging disordered eating symptoms in adolescence predict adverse physical well being outcomes in middle-aged men and women. Targeted interventions and preventative work during adolescence are needed.

AB - Two-dimensional (2D) materials and ultrathin nanosheets are advantageous for elevating the catalysis performance and elucidating the catalysis mechanism of heterogeneous catalysts, but they are mostly restricted to inorganic or organic materials based on covalent bonds. We report an electrochemical/chemical exfoliation strategy for synthesizing metal-organic 2D materials based on coordination bonds. A catechol functionalized ligand is used as the redox active pillar to construct a pillared-layer framework. When the 3D pillared-layer MOF serves as an electrocatalyst for water oxidation (pH 13), the pillar ligands can be oxidized in situ and removed. The remaining ultrathin (2 nm) nanosheets of the metal-organic layers are an efficient catalyst with overpotentials as low as 211 mV at 10 mA cm-2 and a turnover frequency as high as 30 s-1 at an overpotential of 300 mV. PMID- 29457328 TI - Cognitive performance in late adolescence and long-term risk of early heart failure in Swedish men. AB - AIMS: Heart failure (HF) incidence appears to increase among younger individuals, raising questions of how risk factors affect the younger population. We investigated the association of cognitive performance in late adolescence with long-term risk of early HF. METHODS AND RESULTS: We followed a cohort of Swedish men enrolled in mandatory military conscription in 1968-2005 (n = 1 225 300; mean age 18.3 years) until 2014 for HF hospitalization, using data from the Swedish National Inpatient Registry. Cognitive performance (IQ) was measured through a combination of tests, separately evaluating logical, verbal, visuospatial, and technical abilities. The results were standardized, weighted, and presented as stanines of IQ. The association between IQ and risk of HF was estimated using Cox proportional hazards models. In follow-up, there were 7633 cases of a first HF hospitalization (mean age at diagnosis 50.1 years). We found an inverse relationship between global IQ and risk of HF hospitalization. Using the highest IQ stanine as reference, the adjusted hazard ratio for the lowest IQ with risk of HF was 3.11 (95% confidence interval 2.60-3.71), corresponding to a hazard ratio of 1.32 (95% CI 1.28-1.35) per standard deviation decrease of IQ. This association proved persistent across predefined categories of HF with respect to pre-existing or concomitant co-morbidities; it was less apparent among obese conscripts (P for interaction =0.0004). CONCLUSION: In this study of young men, IQ was strongly associated with increased risk of early HF. The medical profession needs to be aware of this finding so as to not defer diagnosis. PMID- 29457330 TI - Modeling suicide in bipolar disorders. AB - INTRODUCTION: Suicide is a multicausal human behavior, with devastating and immensely distressing consequences. Its prevalence is estimated to be 20-30 times greater in patients with bipolar disorders than in the general population. The burden of suicide and its high prevalence in bipolar disorders make it imperative that our current understanding be improved to facilitate prediction of suicide and its prevention. In this review, we provide a new perspective on the process of suicide in bipolar disorder, in the form of a novel integrated model that is derived from extant knowledge and recent evidence. METHODS: A literature search of articles on suicide in bipolar disorder was conducted in recognized databases such as Scopus, PubMed, and PsycINFO using the keywords "suicide", "suicide in bipolar disorders", "suicide process", "suicide risk", "neurobiology of suicide" and "suicide models". Bibliographies of identified articles were further scrutinized for papers and book chapters of relevance. RESULTS: Risk factors for suicide in bipolar disorders are well described, and provide a basis for a framework of epigenetic mechanisms, moderated by neurobiological substrates, neurocognitive functioning, and social inferences within the environment. Relevant models and theories include the diathesis-stress model, the bipolar model of suicide and the ideation-to-action models, the interpersonal theory of suicide, the integrated motivational-volitional model, and the three-step theory. Together, these models provide a basis for the generation of an integrated model that illuminates the suicidal process, from ideation to action. CONCLUSION: Suicide is complex, and it is evident that a multidimensional and integrated approach is required to reduce its prevalence. The proposed model exposes and provides access to components of the suicide process that are potentially measurable and may serve as novel and specific therapeutic targets for interventions in the context of bipolar disorder. Thus, this model is useful not only for research purposes, but also for future real-world clinical practice. PMID- 29457329 TI - The companion dog as a model for human aging and mortality. AB - Around the world, human populations have experienced large increases in average lifespan over the last 150 years, and while individuals are living longer, they are spending more years of life with multiple chronic morbidities. Researchers have used numerous laboratory animal models to understand the biological and environmental factors that influence aging, morbidity, and longevity. However, the most commonly studied animal species, laboratory mice and rats, do not experience environmental conditions similar to those to which humans are exposed, nor do we often diagnose them with many of the naturally occurring pathologies seen in humans. Recently, the companion dog has been proposed as a powerful model to better understand the genetic and environmental determinants of morbidity and mortality in humans. However, it is not known to what extent the age-related dynamics of morbidity, comorbidity, and mortality are shared between humans and dogs. Here, we present the first large-scale comparison of human and canine patterns of age-specific morbidity and mortality. We find that many chronic conditions that commonly occur in human populations (obesity, arthritis, hypothyroidism, and diabetes), and which are associated with comorbidities, are also associated with similarly high levels of comorbidity in companion dogs. We also find significant similarities in the effect of age on disease risk in humans and dogs, with neoplastic, congenital, and metabolic causes of death showing similar age trajectories between the two species. Overall, our study suggests that the companion dog may be an ideal translational model to study the many complex facets of human morbidity and mortality. PMID- 29457331 TI - A strain of Streptomyces sp. isolated from rhizospheric soil of Crataegus oxycantha producing nalidixic acid, a synthetic antibiotic. AB - AIM: Exploration of microbes isolated from rhizospheric soil of Crataegus oxycantha for bioactive natural products. METHODS AND RESULTS: A strain of Streptomyces sp. (C-7) was isolated from rhizospheric soil of C. oxycantha. The 16S rRNA gene sequence of strain C-7 displayed 99% sequence similarity with different Streptomyces species. The highest score was displayed for Streptomyces sp. strain Chy2-8 followed by Streptomyces violarus strain NBRC13104 and Streptomyces arenae strain ISP5293. The position of C-7 in the phylogenetic tree suggested uniqueness of the strain. Nalidixic acid (1), a quinolone antibiotic, was isolated from Streptomyces sp. strain (C-7) for the first time and characterized by NMR and chemically analysed. Compound 1 exhibited antimicrobial activity against Escherichia coli and Pseudomonas aeruginosa. The production of compound 1 was also validated by repeating fermentation of strain C-7 and compound isolation in a separate natural product laboratory with no prior information. Furthermore, Compound 1 showed a cytotoxic effect against human prostate cancer cell line PC3 with an IC50 11 MUg ml-1 . CONCLUSION: To the best of our knowledge, this is the first report showing production of nalidixic acid naturally by a strain of Streptomyces sp. SIGNIFICANCE AND IMPACT OF THE STUDY: In this study, we isolated a strain of Streptomyces sp. producing nalidixic acid, which was otherwise only obtained through chemical synthesis. PMID- 29457332 TI - Association of visit-to-visit blood pressure variability with the risk of all cause mortality and cardiovascular events in general population. AB - The association between blood pressure variability (BPV) and the risk of all cause mortality and cardiovascular diseases (CVD) is not well understood. The Kailuan study is a prospective longitudinal cohort study on cerebrovascular events and cardiovascular factors. In this study, resting blood pressure was measured at baseline and every 2 years from 2006 to 2007. BPV is mainly defined as the coefficient of variation (CV). Hazard ratio (HR), with 95% confidence intervals (CI) was calculated using Cox regression model. Among 52 387 participants, we identified 1817 who ended up with all-cause death and 1198 with CVD. Each 4.68% increase in BPV was associated with a 13% increase in the risk of mortality (HR = 1.13, 95% CI = 1.09-1.18) and a 7% increase in CVD (HR = 1.07, 95% CI = 1.02-1.13), respectively. After adjustment of confounding factors, the HR of comparing participants in the highest versus lowest quartile of CV of systolic blood pressure (SBP) was 1.37 (1.19, 1.57) for all-cause death, 1.18 (1.01, 1.39) for CVD. Similar results were also observed when BPV was measured by different parameters. We concluded that visit-to-visit BPV was associated with all-cause death and cardiovascular and cerebrovascular events in Chinese general population. PMID- 29457333 TI - Bimatoprost sustained-release intracameral implant reduces episcleral venous pressure in dogs. AB - OBJECTIVE: To determine the effect of a bimatoprost sustained-release intracameral implant (Bimatoprost SR) on episcleral venous pressure (EVP) in normal dogs. METHODS: Normotensive beagle dogs were randomized to receive Bimatoprost SR 30 MUg (n = 7) or sham injection (needle insertion only, n = 7) in one eye on day 1. EVP was measured with an episcleral venomanometer through day 65. Episcleral aqueous outflow vessels were identified using fluorescence imaging following intracameral injection of indocyanine green in one additional animal. A separate cohort of dogs that had been trained for conscious intraocular pressure (IOP) measurements received Bimatoprost SR 30 MUg (n = 8) in one eye; IOP was evaluated through day 66. RESULTS: Baseline mean EVP was 10.0 mmHg in the Bimatoprost SR group and 10.4 mmHg in the sham group. Eyes treated with Bimatoprost SR exhibited a transient increase in mean EVP that peaked at day 8, followed by a decrease to levels below baseline. From day 29 to day 65, the change in mean EVP from baseline ranged from -2.4 to -3.9 mmHg (P < 0.05 vs. sham). Baseline mean IOP in eyes treated with Bimatoprost SR was 14.9 mmHg, and a steady IOP reduction was maintained through day 66. Bimatoprost SR-treated eyes exhibited a selective, sustained dilation of aqueous outflow vessels that was not observed in sham-treated eyes. CONCLUSIONS: In normal dogs, Bimatoprost SR was associated with a transient increase in EVP followed by a sustained decrease. Changes in EVP were accompanied by a sustained dilation of aqueous outflow vessels. PMID- 29457334 TI - Establishing a successful perioperative geriatric service in an Australian acute surgical unit. AB - BACKGROUND: The purpose of this study was to assess the impact of a perioperative geriatric service (PGS) in an acute surgical unit (ASU) on patient and organizational outcomes. METHODS: Single centre retrospective cohort study. Inclusion criteria were patients over the age of 65 admitted to the ASU between January and June 2014 (pre-PGS) and 2015 (post-PGS). Chart reviews were performed to identify outcomes of interest including in-hospital morbidity and mortality, length of stay (LOS), 30-day representation and mortality. RESULTS: Geriatric admissions increased by 32% over the two study periods (154 pre-PGS and 203 post PGS). Surgical intervention increased by 11% (P = 0.01). Significantly more medical complications (14% versus 33%, P < 0.001) were identified after the implementation of the PGS. Recognition of delirium in the over 80s also increased by 57%. Rate of surgical complications was unchanged over the study (28% pre-PGS and 34% post-PGS, P = 0.6). In-hospital (<1%, P = 0.5) and 30-day mortality (<1%, P = 0.6) remained low, as did 30-day representation (10% versus 8%, P = 0.5). A trend towards decreased LOS of 1 day was identified after the implementation of the PGS (P = 0.07). CONCLUSION: This study demonstrated successful implementation of a PGS into an ASU. This multi-disciplinary approach has been effective in maintaining low numbers of surgical complications, in-hospital mortality, LOS and patient representations despite an increased number of medical complications. This likely reflects more timely recognition and intervention of medically unwell patients with the PGS. PMID- 29457335 TI - Relation of serum uric acid to an exaggerated systolic blood pressure response to exercise testing in men with normotension. AB - The authors investigated the hypothesis that high serum uric acid concentrations may be related to an exaggerated systolic blood pressure (SBP) response to maximal exercise testing in men with normotension, independent of potential confounding variables. In 4640 healthy men with normotension who underwent maximal treadmill exercise testing and fasting blood chemistry studies, including serum uric acid concentrations, an exaggerated SBP response, defined as SBP >= 210 mm Hg, was detected in 152 men (3.3%). After adjusting for potential confounders, participants in the highest quartile of serum uric acid (>6.6 mg/dL) had a higher odds ratio of demonstrating an exaggerated SBP to maximal exercise (odds ratio, 2.19; 95% confidence interval, 1.24-3.86) compared with participants in the lowest quartile of serum uric acid (<5.1 mg/dL). High serum uric acid concentrations are associated with an exaggerated SBP response to maximal exercise testing in men with normotension, independent of established coronary risk factors. PMID- 29457336 TI - High school biology students use of visual molecular dynamics as an authentic tool for learning about modeling as a professional scientific practice. AB - Modeling is a practice of science that is underemphasized in biology classrooms in comparison to its central focus in the physical sciences. Visualizations of the submicroscopic world of molecules are becoming increasingly sophisticated with the evolution of new technologies. With this in mind, we introduced high school biology classrooms to a professional molecular modeling software program used by research biochemists to visualize proteins and other macromolecules. Analysis of surveys completed before and after the use of the program revealed significant student gains in their understandings of the nature of models. Student and teacher perceptions of the program showed an appreciation for the real/authentic nature of the program, and its affordances when utilizing the three-dimensional rendering of proteins. The teachers did report a general level of frustration regarding their lack of experience with the program and their inability to unlock its full potential due to not being able to access all of the program's features. However, we believe that the evidence at hand indicates that the value of introducing students to authentic molecular modeling tools in high school science classrooms outweighs the potential limitations.

PMID- 29457337 TI - A novel rotational matrix and translation vector algorithm: geometric accuracy for augmented reality in oral and maxillofacial surgeries. AB - BACKGROUND: Augmented reality-based surgeries have not been successfully implemented in oral and maxillofacial areas due to limitations in geometric accuracy and image registration. This paper aims to improve the accuracy and depth perception of the augmented video. METHODOLOGY: The proposed system consists of a rotational matrix and translation vector algorithm to reduce the geometric error and improve the depth perception by including 2 stereo cameras and a translucent mirror in the operating room. RESULTS: The results on the mandible/maxilla area show that the new algorithm improves the video accuracy by 0.30-0.40 mm (in terms of overlay error) and the processing rate to 10-13 frames/s compared to 7-10 frames/s in existing systems. The depth perception increased by 90-100 mm. CONCLUSION: The proposed system concentrates on reducing the geometric error. Thus, this study provides an acceptable range of accuracy with a shorter operating time, which provides surgeons with a smooth surgical flow.

PMID- 29457339 TI - Subjective sleep quality, blood pressure, and hypertension: a meta-analysis. AB - Sleep quality is an important aspect of sleep, but no meta-analysis has elucidated its relationship with blood pressure (BP) and hypertension. A meta analysis was conducted in October 2016 using multiple databases, including Embase and Medline. Studies that assessed subjective sleep quality and BP or hypertension were included. Upon full-text evaluation, 29 articles from 45 041 patients were selected, of which 22 articles were included in the meta-analysis and seven were presented narratively. Poor sleep quality was significantly associated with a greater likelihood of hypertension (odds ratio, 1.48; P value = .01). Poor sleepers had higher average systolic BP (mean difference = 4.37, P value = .09) and diastolic BP (mean difference = 1.25, P value = .32) than normal sleepers without statistical significance. Patients with hypertension had significantly worse sleep quality scores (mean difference = 1.51, P value < .01), while BP dippers had significantly better scores (mean difference = -1.67, P value < .01). The findings highlight the relationship between sleep quality and hypertension. PMID- 29457340 TI - Key Role of TFEB Nucleus Translocation for Silver Nanoparticle-Induced Cytoprotective Autophagy. AB - Transcription factor EB (TFEB) is a master regulator of autophagy and lysosomal biogenesis. Here, silver nanoparticles (Ag NPs)-induced cytoprotective autophagy required TFEB is shown. Ag NPs-induced nucleus translocation of TFEB through a well-established mechanism involving dephosphorylation of TFEB at serine-142 and serine-211 but independent of both the mTORC1 and ERK1/2 pathways. TFEB nucleus translocation precedes autophagy induced by Ag NPs and leads to enhanced expression of autophagy-essential genes. Knocking down the expression of TFEB attenuates the autophagy induction is demonstrated, and in the meantime, enhanced cell killing in HeLa cells treats with Ag NPs, indicating that TFEB is the key mediator for Ag NPs-induced cytoprotective autophagy. The results pinpoint TFEB as a potential target for developing more effective Ag NPs-based cancer therapeutics. PMID- 29457341 TI - Dietary potassium and cardiovascular profile.

AB - BACKGROUND: Sensor-guided assessment for soft tissue balance in total knee arthroplasty (TKA) has been reported to improve patient satisfaction and self reported outcome scores. As more surgeons adopt this technology in TKA, we performed this study to identify if there is a learning curve with its use. METHODS: Analysis of a total of 90 consecutive cases was performed in this study. Initial and final intercompartmental pressure differences were recorded before and after knee ligament balancing. The first 45 patients (group 1) were compared to the last 45 patients (group 2) in terms of operative time and the final state of knee balance. A balanced knee was defined as pressure difference between medial and lateral compartments of <=15 pounds. RESULTS: Group 1 had 10 unbalanced knees in the final pressure difference assessment, while all cases in group 2 were balanced (P < 0.001). There was no statistically significant difference in mean operative time between the two groups. A scatter plot of intercompartmental pressure difference identified that after 30 cases, the capacity to achieve knee ligament balance improved. CONCLUSION: This study suggests that there is a learning curve with the use of sensor-guided assessment in TKA in achieving knee balance; however, the differences noted between initial and final groups were small and may not be of clinical significance.

AB - Compared to single metallic Ni or Co phosphides, bimetallic Ni-Co phosphides own ameliorative properties, such as high electrical conductivity, remarkable rate capability, upper specific capacity, and excellent cycle performance. Here, a simple one-step solvothermal process is proposed for the synthesis of bouquet like cobalt-doped nickel phosphite (Ni11 (HPO3 )8 (OH)6 ), and the effect of the structure on the pseudocapacitive performance is investigated via a series of electrochemical measurements. It is found that when the cobalt content is low, the glycol/deionized water ratio is 1, and the reaction is under 200 degrees C for 20 h, the morphology of the sample is uniform and has the highest specific surface area. The cobalt-doped Ni11 (HPO3 )8 (OH)6 electrode presents a maximum specific capacitance of 714.8 F g-1 . More significantly, aqueous and solid-state flexible electrochemical energy storage devices are successfully assembled. The aqueous device shows a high energy density of 15.48 mWh cm-2 at the power density of 0.6 KW cm-2 . The solid-state device shows a high energy density of 14.72 mWh cm-2 at the power density of 0.6 KW cm-2 . These excellent performances confirm that the cobalt-doped Ni11 (HPO3 )8 (OH)6 are promising materials for applications in electrochemical energy storage devices. PMID- 29457345 TI - Robot-assisted vs freehand pedicle screw fixation in spine surgery - a systematic review and a meta-analysis of comparative studies. AB - BACKGROUND: Medical robotics has progressively become more compelling in modern orthopaedic surgery. Several studies comparing robot-assisted (RA) and freehand (FH) conventional techniques for pedicle screw fixation have been published, but the results are unclear. Here, we assessed current evidence regarding the efficiency, safety and accuracy of RA compared with FH techniques. METHODS: A literature search of PubMed, Embase, the Cochrane Library and Web of Science was performed to compare the differences between RA and FH in spine surgery. Two reviewers independently reviewed included studies, conducted a risk of bias assessment, and extracted data. RESULTS: Three randomized controlled trials (RCTs) and six retrospective comparative studies included a total of 750 patients (3625 pedicle screws). No significant differences were noted between RA and FH in pedicle screw accuracy (95.5% compared with 92.9%; odds ratio: 1.35; 95% confidence interval [CI], 0.55 to 3.30; P=0.51), overall complication rate (1.33% compared with 3.45%; odds ratio: 0.46; 95% CI, 0.15 to 1.43; P=0.18) and radiation exposure time (weighted mean difference [WMD]:8.49; 95% CI, -15.43 to 32.40; P=0.49). While RA was associated with a longer operative time (WMD: 39.63; 95% CI, 5.27 to 73.99; P= 0.02), percutaneous or minimal robot-assisted pedicle screw fixation (M-RA) had a shorter radiation exposure time than FH (WMD: -33.10; 95% CI, -38.18 to -28.02; P=0.00) CONCLUSIONS: The current literature did not prove that RA supersedes FH, although several studies are more optimistic about this procedure. Future well-designed RCTs assessing RA and FH are needed to confirm and update the findings of this analysis. PMID- 29457346 TI - Dual-Hole Excitons Activated Photoelectrolysis in Neutral Solution. AB - II-VI semiconductors exhibit unique behaviors that can generate dual-holes ("heavy and light"), but the application in photocatalysis is still missing. Herein, an empirical utilization of light/heavy holes in a hybrid metal cluster 2D semiconductor nanoplatelets is reported. This hybrid material can boost the hole-transfer at the surface and suppress the recombination. Different roles are enacted by light-holes and heavy-holes, in which the light-holes with higher energy and mobility can facilitate the slow kinetics of water oxidation and further reduce the onset voltage, while the massive heavy-holes can increase the resulting photocurrent by about five times, achieving a photocurrent of 2 mA cm-2 at 1.23 V versus RHE under AM 1.5 G illumination in nonsacrificial neutral solution. These strategies can be the solutions for photoelectrolysis and be beneficial for sustainable development in solar conversion. PMID- 29457348 TI - Fixed-dose vs free-dose combinations for the management of hypertension-An analysis of 81 958 patients. AB - Fixed-dose combinations (FDC) have been developed to reduce the pill burden for hypertensive patients. Data on fixed-dose or free-dose (freeDC) ramipril/amlodipine (R/A) or candesartan/amlodipine (C/A) combination treatment initiation were assessed. 71 463 patients were prescribed R/A and 10 495 C/A. For both R/A and C/A, FDC patients were younger (both P < .001) and less comorbid. Prior MI (OR: 0.61 and 0.60), prior stroke (OR: 0.68 and 0.70) and CHD (OR: 0.68 and 0.64) were negatively associated with FDC use, whereas hyperlipidemia was positively associated (OR: 1.26 and 1.19). Use of antihypertensive comedication (OR: 0.78; OR: 0.55) and treatment discontinuation within 12 months (HR: 0.65 and 0.82) were less likely in FDC patients, who also showed superior adherence (mean MPR; both P < .001). Cost of the combination was higher for FDCs (both P < .001). FDCs improve persistence and adherence, although they are more commonly prescribed in patients with less cardiovascular disease. PMID- 29457347 TI - Comparison of the Oral Absorption, Distribution, Excretion, and Bioavailability of Zinc Sulfate, Zinc Gluconate, and Zinc-Enriched Yeast in Rats. AB - SCOPE: The oral absorption, distribution, excretion, and bioavailability of zinc sulfate (ZnS), zinc gluconate (ZnG), and zinc-enriched yeast (ZnY) in rats are fully and systemically compared for the first time. METHODS AND RESULTS: After zinc compounds were orally administered to rats at a single dose of 4 mg Zn kg-1 , blood, tissues, urine, and feces at different time points were collected for the quantification of zinc concentration. Blood was also harvested for the zinc assay in the multiple-dose administration. Plasma zinc levels among three zinc compounds showed no difference, and zinc was widely distributed in various tissues with the level sequence of bone > liver > pancreas > testes. The net Zn balance was 2.993, 5.125, and 7.482% for ZnS, ZnG, and ZnY, respectively. CONCLUSION: ZnS, ZnG, and ZnY show equivalent bioavailability based on plasma and tissues zinc levels, although ZnY was statistically more absorbed and retained than ZnS and ZnG based on the excretion amount. PMID- 29457349 TI - Impact of Glutathione Modulation on Stability and Pharmacokinetic Profile of Redox-Sensitive Nanogels. AB - Nanoparticles degradable upon external stimuli combine pharmacokinetic features of both small molecules as well as large nanoparticles. However, despite promising preclinical results, several redox responsive disulphide-linked nanoparticles failed in clinical translation, mainly due to their unexpected in vivo behavior. Glutathione (GSH) is one of the most evaluated antioxidants responsible for disulfide degradation. Herein, the impact of GSH on the in vivo behavior of redox-sensitive nanogels under physiological and modulated conditions is investigated. Labelling of nanogels with a DNA-intercalating dye and a radioisotope allows visualization of the redox responsiveness at the cellular and the systemic levels, respectively. In vitro, efficient cleavage of disulphide bonds of nanogels is achieved by manipulation of intracellular GSH concentration. While in vivo, the redox-sensitive nanogels undergo, to a certain extent, premature degradation in circulation leading to rapid renal elimination. This instability is modulated by transient inhibition of GSH synthesis with buthioninsulfoximin. Altered GSH concentration significantly changes the in vivo pharmacokinetics. Lower GSH results in higher elimination half-life and altered biodistribution of the nanogels with a different metabolite profile. These data provide strong evidence that decreased nanogel degradation in blood circulation can limit the risk of premature drug release and enhance circulation half-life of the nanogel. PMID- 29457350 TI - Reactivating Catalytic Surface: Insights into the Role of Hot Holes in Plasmonic Catalysis. AB - Surface plasmon resonance of coinage metal nanoparticles is extensively exploited to promote catalytic reactions via harvesting solar energy. Previous efforts on elucidating the mechanisms of enhanced catalysis are devoted to hot electron induced photothermal conversion and direct charge transfer to the adsorbed reactants. However, little attention is paid to roles of hot holes that are generated concomitantly with hot electrons. In this work, 13 nm spherical Au nanoparticles with small absorption cross-section are employed to catalyze a well studied glucose oxidation reaction. Density functional theory calculation and X ray absorption spectrum analysis reveal that hot holes energetically favor transferring catalytic intermediates to product molecules and then desorbing from the surface of plasmonic catalysts, resulting in the recovery of their catalytic activities. The studies shed new light on the use of the synergy of hot holes and hot electrons for plasmon-promoted catalysis. PMID- 29457351 TI - 24-hour aortic blood pressure variability showed a stronger association with carotid damage than 24-hour brachial blood pressure variability: The SAFAR study. AB - We aim to compare 24-hour aortic blood pressure variability (BPV) with brachial BPV in relation to carotid damage as estimated by carotid intima-media thickness (CIMT) and cross-sectional area (CCSA). Four hundred and forty five individuals received brachial and aortic 24-hour ambulatory BP monitoring with a validated device (Mobil-O-Graph). Systolic BPV was estimated by average real variability (ARV) and time-weighted standard deviation (wSD). In multiple logistic regression analysis, CIMT > 900 MUm was significantly and independently associated with aortic ARV (OR = 1.38; 95% CI: 1.04-1.84), aortic wSD (OR = 1.65; 95% CI: 1.19 2.29) and brachial ARV (OR = 1.53; 95% CI: 1.07-2.18), but not with brachial wSD. CCSA > 90th percentile was significantly and independently associated with aortic ARV (OR = 1.50; 95% CI: 1.07-2.10) and wSD (OR = 1.70; 95% CI: 1.12-2.56), but not with brachial BPVs. In receiver operator characteristics curve analysis, aortic wSD identified CCSA > 90th percentile better than brachial wSD (AUC: 0.73 vs 0.68, P < .01). In conclusion, aortic 24-hour systolic BPV showed a slightly stronger association with carotid damage than brachial BPV. PMID- 29457352 TI - Controllable Bipolar Doping of Graphene with 2D Molecular Dopants. AB - The fine control of graphene doping levels over a wide energy range remains a challenging issue for the electronic applications of graphene. Here, the controllable doping of chemical vapor deposited graphene, which provides a wide range of energy levels (shifts up to +/- 0.5 eV), is demonstrated through physical contact with chemically versatile graphene oxide (GO) sheets, a 2D dopant that can be solution-processed. GO sheets are a p-type dopant due to their abundance of electron-withdrawing functional groups. To expand the energy window of GO-doped graphene, the GO surface is chemically modified with electron donating ethylene diamine molecules. The amine-functionalized GO sheets exhibit strong n-type doping behaviors. In addition, the particular physicochemical characteristics of the GO sheets, namely their sheet sizes, number of layers, and degree of oxidation and amine functionality, are systematically varied to finely tune their energy levels. Finally, the tailor-made GO sheet dopants are applied into graphene-based electronic devices, which are found to exhibit improved device performances. These results demonstrate the potential of GO sheet dopants in many graphene-based electronics applications. PMID- 29457353 TI - Effect of bristle stiffness of manual toothbrushes on normal and demineralized human enamel-An in vitro profilometric study. AB - OBJECTIVE: To compare the brushing abrasion carried out by manual toothbrushes with different bristle types (hard and soft) on normal and demineralized human enamel. MATERIALS AND METHODS: Thirty enamel blocks (N = 30) were prepared and were randomly divided into three main groups: A, teeth kept in artificial saliva with no brushing (control, n = 2); B, teeth brushed with toothbrushes with hard bristles (n = 14); and C, teeth brushed with toothbrushes with soft bristles (n = 14). Seven teeth belonging to groups B and C were brushed normally, and the remaining seven were demineralized before brushing experiments with 6 wt.% citric acid (pH = 2.2) for 5 minutes. The brushing experiments were carried out twice a day for 2 mins for 7 days inside a toothbrush simulation machine. The changes in the surface of enamel (prebrushing and post-brushing) were evaluated using non contact profilometry. The results were analysed statistically using Kruskal Wallis test and the Wilcoxon signed rank test. RESULTS: For both normal and demineralized enamel, toothbrushes with soft bristles caused more abrasion. The results revealed significant differences (P = .055) in the surface roughness values between the four groups prebrushing. Within each group, the prebrushing and post-brushing surface roughness value differences were all statistically significant (P < .05). CONCLUSIONS: The results demonstrate that soft bristles caused more abrasion as compared with the hard bristles. These results could have an impact on the toothbrush recommendations for patients. PMID- 29457354 TI - Nitrogen-Enriched Carbon/CNT Composites Based on Schiff-Base Networks: Ultrahigh N Content and Enhanced Lithium Storage Properties. AB - To improve the electrochemical performance of carbonaceous anodes for lithium ion batteries (LIBs), the incorporation of both well-defined heteroatom species and the controllable 3D porous networks are urgently required. In this work, a novel N-enriched carbon/carbon nanotube composite (NEC/CNT) through a chemically induced precursor-controlled pyrolysis approach is developed. Instead of conventional N-containing sources or precursors, Schiff-base network (SNW-1) enables the desirable combination of a 3D polymer with intrinsic microporosity and ultrahigh N-content, which can significantly promote the fast transport of both Li+ and electron. Significantly, the strong interaction between carbon skeleton and nitrogen atoms enables the retention of ultrahigh N-content up to 21 wt% in the resultant NEC/CNT, which exhibits a super-high capacity (1050 mAh g-1 ) for 1000 cycles and excellent rate performance (500 mAh g-1 at a current density of 5 A g-1 ) as the anode material for LIBs. The NEC/CNT composite affords a new model system as well as a totally different insight for deeply understanding the relationship between chemical structures and lithium ion storage properties, in which chemistry may play a more important role than previously expected. PMID- 29457355 TI - Visceral obesity is a significant risk factor for incisional hernia after laparoscopic colorectal surgery: A single-center review. AB - INTRODUCTION: Although laparoscopic surgery uses relatively small incisions, incisional hernia after surgery is not uncommon. However, the incidence of incisional hernia and its risk factors are not well known. The purpose of our study was to investigate risk factors for incisional hernia after laparoscopic colorectal cancer surgery. METHODS: The study group consisted of 212 patients who underwent laparoscopic colorectal cancer surgery at Hiroshima Prefectural Hospital between November 2008 and October 2013. Diagnosis of incisional hernia was performed by postoperative CT. The visceral fat area (VFA) and subcutaneous fat area at the level of the umbilicus were calculated using an image analysis system. For statistical analysis, Fisher's exact test or Student's t-test were used for univariate analysis, and logistic regression analysis was used for multivariate analysis. The cut-off value for risk factors was calculated from the receiver-operator curve. RESULTS: Incisional hernia was observed in 18 patients (8.5%). On univariate analysis, female sex (P = 0.04), older age (P = 0.02), subcutaneous fat area (P < 0.01), VFA (P = 0.02), and BMI >25 kg/m2 (P < 0.01) were significant risk factors for incisional hernia. The predictive cut-off values were as follows: age, 72 years; subcutaneous fat area, 110 cm2 ; VFA, 110 cm2 ; and albumin concentration, 3.9 g/dL. On multivariate analysis, a VFA >110 cm2 (P < 0.01) and female sex (P = 0.01) were retained as independent risk factors for incisional hernia. CONCLUSION: After laparoscopic colorectal cancer surgery, a higher VFA and female sex are independent risk factors for incisional hernia.

PMID- 29457357 TI - Improving outpatient advance care planning for adults with congenital or pediatric heart disease followed in a pediatric heart failure and transplant clinic. AB - OBJECTIVE: To improve outpatient advanced care planning (ACP) for adults with congenital/pediatric heart disease followed in a pediatric heart failure (HF) and transplant clinic through quality improvement (QI) methodology. DESIGN: A one year QI project was completed. We conducted quarterly chart reviews and incorporated feedback from the providers to direct subsequent interventions. PATIENTS AND SETTING: Patients >=18 years of age seen in the HF and Transplant Clinic for follow-up visit were included in analysis. INTERVENTIONS: Interventions focused on five main areas: identifying and training providers to have ACP discussions, standardizing the ACP discussion, standardizing ACP and advance directive (AD) documentation in the electronic medical record, preparing providers to have ACP conversations, and preparing patients to engage in ACP and AD completion. OUTCOME MEASURES: The outcome measure was percent of adults seen in the HF and Transplant Clinic per month with documented AD (goal 50%). The process measure was percent of adults seen in the HF and Transplant Clinic per month with a documented ACP discussion (goal 100%). RESULTS: At baseline, no patients had a documented ACP discussion or AD. Fifty-eight adults (mean age 20.4 +/- 2.1 years) were seen from March 2016 to February 2017 for a total of 130 visits. In the final month of our study, 75% of adult encounters had a documented ACP discussion and 42% had a documented AD. CONCLUSIONS: The percentage of documented ADs in adults seen in the HF and Transplant Clinic at a quaternary children's hospital improved through a QI initiative. Over 50% of patients who were engaged in an ACP discussion completed an AD, suggesting this population is receptive to ACP and AD completion. PMID- 29457358 TI - CRT Survey II: a European Society of Cardiology survey of cardiac resynchronisation therapy in 11 088 patients-who is doing what to whom and how? AB - BACKGROUND: Cardiac resynchronisation therapy (CRT) reduces morbidity and mortality in appropriately selected patients with heart failure and is strongly recommended for such patients by guidelines. A European Society of Cardiology (ESC) CRT survey conducted in 2008-2009 showed considerable variation in guideline adherence and large individual, national and regional differences in patient selection, implantation practice and follow-up. Accordingly, two ESC associations, the European Heart Rhythm Association and the Heart Failure Association, designed a second prospective survey to describe contemporary clinical practice regarding CRT. METHODS AND RESULTS: A survey of the clinical practice of CRT-P and CRT-D implantation was conducted from October 2015 to December 2016 in 42 ESC member countries. Implanting centres provided information about their hospital and CRT service and were asked to complete a web-based case report form collecting information on patient characteristics, investigations, implantation procedures and complications during the index hospitalisation. The 11 088 patients enrolled represented 11% of the total number of expected implantations in participating countries during the survey period; 32% of patients were aged >=75 years, 28% of procedures were upgrades from a permanent pacemaker or implantable cardioverter-defibrillator and 30% were CRT-P rather than CRT-D. Most patients (88%) had a QRS duration >=130 ms, 73% had left bundle branch block and 26% were in atrial fibrillation at the time of implantation. Large geographical variations in clinical practice were observed. CONCLUSION: CRT Survey II provides a valuable source of information on contemporary clinical practice with respect to CRT implantation in a large sample of ESC member states. The survey permits assessment of guideline adherence and demonstrates variations in patient selection, management, implantation procedure and follow-up strategy.

PMID- 29457360 TI - Neglected areas on thorax computed tomography evaluation in patients with chronic obstructive pulmonary disease: Paravertebral muscles and para-aortic adipose tissue. AB - INTRODUCTION: This study, investigated the para-aortic adipose tissue cross sectional area, a novel predictor of cardiovascular diseases and degenerative changes in the paravertebral muscles, in patients with chronic obstructive pulmonary disease (COPD). METHOD: One hundred cases diagnosed as COPD and 50 healthy individuals with similar demographic characteristics were evaluated. Para aortic adipose tissue cross-sectional area (mm2 ), subcutaneous adipose tissue thickness (mm), paravertebral muscle area (mm2 ) and fat deposition in muscle tissue were assessed radiologically. RESULTS: Paravertebral muscle mass was lower in the patient group compared to the healthy individuals (471.41 +/- 157.71 mm2 and 561.58 + 151.03 mm2 , respectively; P = 0.001). Paravertebral muscle attenuation values were also lower in the patient group, and the grade of deposition increased (P = 0.012 and P = 0.045, respectively). Although subcutaneous adipose tissue thicknesses were similar in the patient and control groups, para-aortic adipose tissue cross-sectional area was higher in the patients with COPD than in the control group (439.34 +/- 267.17 mm2 and 333.82 +/ 165.23 mm2 , respectively, P = 0.012). The correlation between subcutaneous adipose tissue and para-aortic adipose tissue observed in the healthy group was not present in the subjects with COPD. CONCLUSION: Chronic obstructive pulmonary disease causes morphological changes in paravertebral muscles and para-aortic adipose tissue. Degenerative changes in the paravertebral muscles occur secondary to systemic inflammation, comorbidity and drugs used in COPD. Factors such as insulin resistance and steroid use result in an increase in para-aortic adipose tissue mass. PMID- 29457361 TI - Cognitive function and unsafe driving acts during an on-road test among community dwelling older adults with cognitive impairments. AB - AIM: To examine the relationship between cognitive function and unsafe driving acts among community-dwelling older adults with cognitive impairments. METHODS: Participants (n = 160) were older residents of Obu, Japan, aged >=65 years with cognitive impairments. They regularly drove and were assessed for the number of unsafe driving acts without adequate verification during an on-road test. We also evaluated cognitive function (attention, executive function and processing speed). Other examined variables included demographics, driving characteristics and visual condition. RESULTS: Participants were classified into two groups according to the number of unsafe driving acts as follows: high group (>=4 unsafe driving acts) and low group (<=3 unsafe driving acts). The high group participants were older in age (P < 0.001) and obtained a lower score on the symbol digit substitution task (P = 0.002) than the low group. The number of unsafe driving acts showed modest significant positive correlations with age (r = 0.396, P < 0.001). The symbol digit substitution task score was significantly associated with the number of unsafe driving acts (beta = -0.196, P < 0.05) after adjusting for age group. CONCLUSIONS: Processing speed was associated with unsafe driving acts that became worse with increasing age. Future study will be required to longitudinally examine the influence of processing speed on traffic accidents for those with cognitive impairments. Geriatr Gerontol Int 2018; 18: 847-852. PMID- 29457363 TI - Conventional laparoscopic appendectomy versus double-incision, three-port laparoscopic appendectomy: A 1-year randomized controlled trial. AB - INTRODUCTION: Management of appendicitis has evolved dramatically in the last 120 years, from McBurney's large incision to minimally invasive laparoscopic appendectomy to hardly noticeable incisions with SILS. As a bridge between conventional laparoscopic surgery and SILS, double-incision laparoscopic surgery further minimizes the invasiveness of laparoscopic surgery by reducing the number of incisions. This study aimed to establish the efficacy of double-incision, three-port laparoscopic appendectomy (DILA) as an alternative to conventional three-port laparoscopic appendectomy. METHODS: A total of 60 patients were divided randomly into two groups: the conventional laparoscopic appendectomy (CLA) group and the DILA appendectomy group. Demographics, diagnostic history, additional intraoperative findings, and duration of operation were recorded. Postoperative pain after 6 h and 24 h and cosmetic outcome after the surgery were also evaluated. Statistical analysis was done using Fisher's exact test, chi2 test, and Student's t-test. RESULTS: No significant difference was observed in demographic and clinical characteristics in either group (P > 0.05). No significant difference in mean postoperative pain was observed between the two groups at 6 h (P = 0.62) or 24 h (P = 0.484). However, patients in the DILA group were more satisfied with their cosmetic outcomes than those in the CLA group (P = 0.04). The mean operative time was 26.4 min in the CLA group and 27.6 min in the DILA group (P = 0.62). CONCLUSION: DILA can be performed with operative outcomes that are equivalent to CLA but with superior cosmetic outcomes. PMID- 29457364 TI - Transmission electron microscopy analysis of the origin and incidence of sperm intranuclear cytoplasmic retention in fertile and teratozoospermia men. AB - The human sperm nucleus contains cytoplasm. However, the origin and incidence of human sperm intranuclear cytoplasmic retention (INCR) remain unknown. The objectives of this study were to observe the morphological origin of INCR within the seminiferous epithelium and investigate the incidence of INCR in fertile and teratozoospermia men using transmission electron microscopy (TEM). By TEM, INCR initially appeared in elongating round spermatid nuclei and varied in size, number, shape, content, location and distribution within sperm nuclei. The teratozoospermia group (n = 16) demonstrated a higher incidence of INCR than did the fertile group (n = 16) (17.6 +/- 5.2% vs. 9.7 +/- 3.4%; p = 0.000). In the fertile group, no correlations were found between the incidence of INCR and abnormal sperm morphology, nuclear vacuole, acrosome integrity, motility or concentration (p > 0.05). However, the incidence of INCR exhibited a positive relationship with sperm abnormal morphology in the teratozoospermia group (r = 0.616, p = 0.011). These results demonstrate that INCR occurs in the early process of spermatogenesis and is an alteration found in the nucleus. Spermatozoa from teratozoospermia men contained more INCRs than those from fertile males. More attention should be paid to the possibility of spermatozoa containing INCR when using spermatozoa with abnormal head morphology for clinical or diagnostic purposes. PMID- 29457362 TI - A multinational observational investigation of illness perceptions and quality of life among patients with a Fontan circulation. AB - OBJECTIVE: First, to compare QOL and illness perceptions between patients with a Fontan circulation and patients with anatomically simple defects (ie, atrial septal defects [ASD] or ventricular septal defects [VSD]). Second, to explore illness perceptions as a mediator of the association between congenital heart disease (CHD) diagnosis and QOL. DESIGN: Cross-sectional observational study. SETTING: Twenty-four cardiology centers from 15 countries across five continents. PATIENTS: Four hundred thirty-five adult patients with congenital heart disease (177 Fontan and 258 ASD/VSD) ages 18-83 years. OUTCOME MEASURES: QOL and illness perceptions were assessed by the Satisfaction With Life Scale and the Brief Illness Perceptions Questionnaire, respectively. RESULTS: Patients with a Fontan circulation reported lower QOL (Wald Z = -3.59, p = <.001) and more negative perceptions of their CHD (Wald Z = -7.66, p < .001) compared with patients with ASD/VSD. After controlling for demographics, anxiety, depressive symptoms, and New York Heart Association functional class, path analyses revealed a significant mediation model, alphabeta = 0.15, p = .002, 95% CI = 0.06-0.25, such that CHD diagnosis was indirectly related to QOL through illness perceptions. CONCLUSIONS: The Fontan sample's more negative perceptions of CHD were likely a reflection of life with a more complex defect. Illness perceptions appear to account for unique differences in QOL between groups of varying CHD complexity. Psychosocial screening and interventions may be important treatment components for patients with CHD, particularly those with Fontan circulations. PMID- 29457365 TI - Male infertility is associated with altered treatment course of men with cancer. AB - This study aims to evaluate whether cancer treatments differ in infertile men compared to men who have undergone vasectomy and age-matched controls. We analyzed subjects from the Truven Health MarketScan Claims database from 2001 to 2009. Infertile men were identified through diagnosis and treatment codes. Comparison groups included vasectomized men and an age-matched cohort who were not infertile and had not undergone vasectomy. We considered cancer types previously associated with infertility that were diagnosed after the diagnosis of infertility. The treatment regimens were determined based on the presence of claims with CPT codes for chemotherapy (CTX), radiation (RTX) or surgical treatment (ST) for each entity in all study groups. Cases with multimodal treatments were also identified. As a result, CTX was similarly distributed among the infertile, vasectomized, and control groups. In contrast, RTX treatment length was shorter in infertile men. The frequency of multimodal treatment (i.e., radiation and chemotherapy) was twofold lower in men with infertility compared to other men. By focusing on treatment patterns for each cancer type among these groups, the duration of RTX and CTX was shorter in infertile men diagnosed with NHL compared to controls. We conclude that Infertile men diagnosed with cancer and specific cancer types experience different treatment courses, with shorter RTX and less combined RTX/CTX compared to fertile and vasectomized men. These differences could reflect differences in stage at presentation, biological behavior, or treatment responses in infertile men. PMID- 29457366 TI - Is the laparoscopic approach appropriate for pediatric subhepatic appendicitis? AB - INTRODUCTION: Subhepatic appendicitis in children is an unusual condition that can be challenging for the pediatric surgeons to treat. The aim of our study was to compare the outcomes of laparoscopic appendectomies based on the position of the appendix. METHODS: The data of 1736 patients who had undergone laparoscopic appendectomy in our tertiary center were retrospectively reviewed. We compared two groups: subhepatic location (n = 56) and non-subhepatic location (n = 1680). A P-value of less than 0.05 was considered statistically significant. RESULTS: There was no statistically significant difference between the demographic variables of the groups. More than half of the subhepatic appendicitises were gangrenous (44.6%) or perforated (16.1%), whereas most of the non-subhepatic appendicitises were phlegmonous (56.9%). Extracorporeal ligation of the appendix was the preferred technique in both the subhepatic and non-subhepatic groups (69.6% and 89.8%, respectively). The subhepatic group had a statistically significant higher incidence of technical difficulties (1.6%) and abdominal drain (18.6%) than the non-subhepatic group, as well as a longer operative time and hospital stay. However, intraoperative and postoperative complications were similar in both groups. CONCLUSION: Laparoscopic subhepatic appendectomy is safe and does not lead to increased complications. However, the technique is made difficult by the fact that the appendix is an atypical location, and the rate of complicated appendicitis is higher. PMID- 29457367 TI - Sperm morphological normality under high magnification is correlated to male infertility and predicts embryo development. AB - Human sperm morphology has been described as an essential parameter for the diagnosis of male infertility and a prognostic indicator of natural or assisted pregnancies. Nevertheless, standard morphological assessment remains a subjective analysis and its impact on intracytoplasmic sperm injection (ICSI) is also of limited value. The objective of this prospective cohort study was to investigate whether motile sperm organelle morphology examination (MSOME) can improve semen analysis by better defining male infertility and providing a better prognosis for ICSI up to a year later. Data were obtained from 483 patients undergoing conventional semen analysis from June 2015 to June 2017 in a private university affiliated in vitro fertilization (IVF) center. The correlation of MSOME with seminal parameters was evaluated. One hundred and thirty patients underwent ICSI up to a year later, and the correlation between MSOME and ICSI outcomes was established. Except for volume, all seminal parameters were positively correlated with MSOME I+II. MSOME was also distinct between World Health Organization (WHO) classification groups, with normozoospermic and oligoasthenoteratozoospermic presenting the higher and the lower proportion of MSOME I+II, respectively. MSOME I+II was prognostic for fertilization rate, high-quality cleavage-stage embryos rate, and blastocyst rate. The normality cutoff value based on blastocyst rate was MSOME I+II>= 5.5%. MSOME could be a useful tool for the diagnosis of infertility severity as it is correlated with sperm morphology, motility, and concentration. Men who had higher MSOME I+II had better ICSI outcomes. The future use of MSOME as a routine method for semen analysis may be a reliable form of assessing male infertility. PMID- 29457369 TI - Internet Searches for Affect-Related Terms: An Indicator of Subjective Well-Being and Predictor of Health Outcomes across US States and Metro Areas. AB - BACKGROUND: The present study explored the potential for internet search data to serve as indicators of subjective well-being (SWB) and predictors of health at the state and metro area levels. We propose that searches for positive and negative affect-related terms represent information-seeking behavior of individuals who are experiencing emotions and seeking information about them. METHOD: Data on the frequency of Google searches for 15 affect terms were collected from Google's Trends website (trends.google.com). These were paired with data on health, self-reported emotions, psychological well-being, personality, and Twitter postings at the state and metro area levels. RESULTS: Several internet search scores correlated with indicators of cardiovascular health and depression. Some search term scores also correlated strongly with self reported emotions, well-being metrics, neuroticism, per capita income, and Twitter postings at the state or metro area level. Multiple regression analyses suggest that affect searches predict depression rates at the metro area level beyond the effects of income and other well-being measures. CONCLUSION: The results highlight the promise and challenges of using internet search data at the aggregate level for physical and mental health assessment and surveillance.

AB - Foot-and-mouth disease (FMD) is endemic in Bangladesh, and the implementation of a control programme for this disease is at an early stage, according to the FAO- and OIE-proposed Progressive Control Pathway for FMD (PCP-FMD) Roadmap. To develop an effective control programme, understanding of foot-and-mouth disease virus (FMDV) serotypes, even subtypes within the serotypes is essential. The present investigation aims at viral VP1 coding region sequence-based analysis of FMD samples collected from 34 FMD outbreaks during 2012-2016 in Bangladesh. Foot and-mouth disease virus (FMDV) serotype O was responsible for 82% of the outbreaks in Bangladesh, showing its dominance over serotype A and Asia1. The VP1 phylogeny revealed the emergence of two novel sublineages of serotype O, named as Ind2001BD1 and Ind2001BD2, within the Ind2001 lineage along with the circulation of Ind2001d sublineage in Bangladesh, which was further supported by the multidimensional scaling with distinct clusters for each sublineage. The novel sublineages had evident genetic variability with other established sublineages within Ind2001 lineage. Ten mutations with three or more amino acid variations were detected within B-C loop, G-H loop and C-terminal region of the VP1 protein of FMDV serotype O viruses isolated exclusively from Bangladesh. Furthermore, two amino acid substitutions at positions 197 and 198 within the VP1 C-terminal region are unique to the novel sublineages. The existence of widespread genetic variations among circulatory FMDV serotype O viruses makes the FMD control programme complex in Bangladesh. Adequate epidemiological data, disease reporting, animal movement control, appropriate vaccination and above all stringent policies of the government are necessary to combat FMD in Bangladesh.

AB - Avian metapneumovirus (aMPV) is an emerging poultry pathogen that has a significant economic impact on poultry production worldwide. The geographic range of the virus continues to expand, and wild birds have been implicated as reservoirs of aMPV that have the potential to spread the virus over long distances. Our objective was to determine the apparent prevalence of aMPV subtype C in wild waterfowl in Ontario, Canada. Wild waterfowl were captured in August and September, 2016 as part of routine migratory waterfowl population monitoring by the Ontario Ministry of Natural Resources and Forestry. Oropharyngeal and cloacal swabs were collected from each bird and placed together for aMPV testing using real-time RT-PCR. A total of 374 live wild birds from 23 lakes were sampled and tested for aMPV. Among all ducks tested, 84 (22%) were positive for aMPV. The proportion of samples that tested positive ranged from 0% in ring-necked ducks (Aythya collaris) and green-winged teal (Anas carolinensis) to 44% (8 of 18) in American black ducks (A. rubripes). Waterfowl positive for aMPV were found at 14 of 23 lakes in the study area and the percent positive at these 14 lakes ranged between 5% and 84%. Although subtype C aMPV has been detected in a variety of wild birds in North America, this is the first report of aMPV in wild ducks in Ontario, Canada. The high apparent prevalence, particularly in mallards and American black ducks (37 and 44%, respectively), suggests that these species may be important reservoirs of aMPV. Given the potential impact of aMPV on domestic poultry and the potential role of wild birds as reservoirs of the virus, further investigation of the geographic distribution, risk factors associated with aMPV carriage in wild waterfowl and potential role of other birds in the epidemiology of aMPV in Canada is warranted. PMID- 29457371 TI - Validation of a blood marker for plasma volume in endurance athletes during a live-high train-low altitude training camp. AB - Altitude is a confounding factor within the Athlete Biological Passport (ABP) due, in part, to the plasma volume (PV) response to hypoxia. Here, a newly developed PV blood test is applied to assess the possible efficacy of reducing the influence of PV on the volumetric ABP markers; haemoglobin concentration ([Hb]) and the OFF-score. Endurance athletes (n=34) completed a 21-night simulated live-high train-low (LHTL) protocol (14 h.d-1 at 3000 m). Bloods were collected twice pre-altitude; at days 3, 8, and 15 at altitude; and 1, 7, 21, and 42 days post-altitude. A full blood count was performed on the whole blood sample. Serum was analysed for transferrin, albumin, calcium, creatinine, total protein, and low-density lipoprotein. The PV blood test (consisting of the serum markers, [Hb] and platelets) was applied to the ABP adaptive model and new reference predictions were calculated for [Hb] and the OFF-score, thereby reducing the PV variance component. The PV correction refined the ABP reference predictions. The number of atypical passport findings (ATPFs) for [Hb] was reduced from 7 of 5 subjects to 6 of 3 subjects. The OFF-score ATPFs increased with the PV correction (from 9 to 13, 99% specificity); most likely the result of more specific reference limit predictions combined with the altitude-induced increase in red cell production. Importantly, all abnormal biomarker values were identified by a low confidence value. Although the multifaceted, individual physiological response to altitude confounded some results, the PV model appears capable of reducing the impact of PV fluctuations on [Hb].

AB - With a view to developing a photoanode for visible light-driven water oxidation in solar water splitting cells, pure-monoclinic WO3 nanorod crystals with N2 intercalated into the lattice were synthesized by using hydrazine with a dual functional role-as an N atom source for the in situ N2 intercalation and as a structure-directing agent for the nanorod architecture-to gain higher incident photon-to-current conversion efficiency at 420 nm than with most previously reported WO3 electrodes. PMID- 29457372 TI - Clinical Characteristics and Factors Associated With Disability and Impaired Quality of Life in Children With Juvenile Systemic Sclerosis: Results From the Childhood Arthritis and Rheumatology Research Alliance Legacy Registry. AB - OBJECTIVE: To investigate clinical manifestations of juvenile systemic sclerosis (SSc; scleroderma), including disease characteristics and patient quality of life, using the multinational Childhood Arthritis and Rheumatology Research Alliance (CARRA) Legacy Registry. METHODS: Patients with juvenile SSc were prospectively enrolled between 2010 and 2013. The diagnosis of juvenile SSc was determined by the enrolling pediatric rheumatologist, with the requirement for disease onset prior to age 18 years. Collected data included demographics, disease characteristics, medication exposure, and quality of life metrics. RESULTS: In total, 64 patients with juvenile SSc were enrolled a median of 3.6 years after disease onset, which occurred at a median age of 10.3 years. The most common organ manifestations were dermatologic and vascular, followed by musculoskeletal, gastrointestinal, and pulmonary; in 38% of patients, >=4 organ systems were affected. Patients with juvenile SSc had significantly more disability at enrollment compared with CARRA Legacy Registry patients with juvenile idiopathic arthritis, dermatomyositis, or systemic lupus erythematosus. Although physician-reported measures correlated most closely with arthritis, dermatologic manifestations, and pulmonary manifestations, poor patient-reported measures were associated with gastrointestinal involvement. During >50 person years of follow-up, most organ manifestations remained stable, and no mortality or development of new solid organ involvement after enrollment was reported. CONCLUSION: In the first multicenter prospective cohort of patients with juvenile SSc in North America, the disease burden was high: multiorgan manifestations were common, and functional disability was greater than that observed in patients with other childhood-onset rheumatic diseases. Gastrointestinal involvement had the greatest impact on quality of life. PMID- 29457374 TI - Impaired Proteasomal Function in Human Osteoarthritic Chondrocytes Can Contribute to Decreased Levels of SOX9 and Aggrecan. AB - OBJECTIVE: Osteoarthritis (OA) chondrocytes exhibit impairment of autophagy, one arm of the proteostasis network that coordinates proteome and organelle quality control and degradation. Deficient proteostasis impacts differentiation and viability, and inflammatory processes in aging and disease. The present study was undertaken to assess ubiquitin proteasome system proteasomal function in OA chondrocytes. METHODS: We evaluated human knee cartilage by immunohistochemistry, and assessed proteasomal function, levels of proteasomal core subunits and chaperones, and autophagy in cultured chondrocytes. Assays included Western blotting, quantitative reverse transcription-polymerase chain reaction, proteasomal protease activity assessment, and cell immunofluorescence analysis. RESULTS: Human knee OA cartilage exhibited polyubiquitin accumulation, with increased ubiquitin K48-linked polyubiquitinated proteins in situ, suggesting proteasomal impairment. Cultured OA chondrocytes demonstrated accumulation of K48 polyubiquitinated proteins, significantly reduced 20S proteasome core protease activity, and decreased levels of phosphorylated FOXO4 and proteasome 26S subunit, non-ATPase 11 (PSMD11), a FOXO4-inducible promoter of proteasomal activation. Levels of proteasome subunit beta type 3 (PSMB3), PSMB5, PSMB6, and proteasome assembly chaperone 1 were not decreased in OA chondrocytes. In normal chondrocytes, PSMD11 small interfering RNA knockdown stimulated certain autophagy machinery elements, increased extracellular nitric oxide (NO) levels, and reduced chondrocytic master transcription factor SOX9 protein and messenger RNA (mRNA) and aggrecan (AGC1) mRNA. PSMD11 gain-of- function by transfection increased proteasomal function, increased levels of SOX9-induced AGC1 mRNA, stimulated elements of the autophagic machinery, and inhibited extracellular levels of interleukin-1-induced NO and matrix metalloproteinase 13 in OA chondrocytes. CONCLUSION: Deficient PSMD11, associated with reduced phosphorylated FOXO4, promotes impaired proteasomal function in OA chondrocytes, dysregulation of chondrocytic homeostasis, and decreased levels of SOX9 mRNA, SOX9 protein, and AGC1 mRNA. Chondrocyte proteasomal impairment may be a therapeutic target for OA. PMID- 29457375 TI - Evidence of Alternative Modes of B Cell Activation Involving Acquired Fab Regions of N-Glycosylation in Antibody-Secreting Cells Infiltrating the Labial Salivary Glands of Patients With Sjogren's Syndrome. AB - OBJECTIVE: To better understand the role of B cells, the potential mechanisms responsible for their aberrant activation, and the production of autoantibodies in the pathogenesis of Sjogren's syndrome (SS), this study explored patterns of selection pressure and sites of N-glycosylation acquired by somatic mutation (acN glyc) in the IgG variable (V) regions of antibody-secreting cells (ASCs) isolated from the minor salivary glands of patients with SS and non-SS control patients with sicca symptoms. METHODS: A novel method to produce and characterize recombinant monoclonal antibodies (mAb) from single cell-sorted ASC infiltrates was applied to concurrently probe expressed genes (all heavy- and light-chain isotypes as well as any other gene of interest not related to immunoglobulin) in the labial salivary glands of patients with SS and non-SS controls. V regions were amplified by reverse transcription-polymerase chain reaction, sequenced, and analyzed for the incidence of N-glycosylation and selection pressure. For specificity testing, the amplified regions were expressed as either the native mAb or mutant mAb lacking the acN-glyc motif. Protein modeling was used to demonstrate how even an acN-glyc site outside of the complementarity-determining region could participate in, or inhibit, antigen binding. RESULTS: V-region sequence analyses revealed clonal expansions and evidence of secondary light chain editing and allelic inclusion, of which neither of the latter two have previously been reported in patients with SS. Increased frequencies of acN-glyc were found in the sequences from patients with SS, and these acN-glyc regions were associated with an increased number of replacement mutations and lowered selection pressure. A clonal set of polyreactive mAb with differential framework region 1 acN-glyc motifs was also identified, and removal of the acN-glyc could nearly abolish binding to autoantigens. CONCLUSION: These findings support the notion of an alternative mechanism for the selection and proliferation of some autoreactive B cells, involving V-region N-glycosylation, in patients with SS. PMID- 29457377 TI - Pseudohalide-Induced 2D (CH3 NH3 )2 PbI2 (SCN)2 Perovskite for Ternary Resistive Memory with High Performance. AB - Recently, organic-inorganic hybrid perovskites (OIHP) are studied in memory devices, but ternary resistive memory with three states based on OIHP is not achieved yet. In this work, ternary resistive memory based on hybrid perovskite is achieved with a high device yield (75%), much higher than most organic ternary resistive memories. The pseudohalide-induced 2D (CH3 NH3 )2 PbI2 (SCN)2 perovskite thin film is prepared by using a one-step solution method and fabricated into Al/perovskite film/indium-tin oxide (glass substrate as well as flexible polyethylene terephthalate substrate) random resistive access memory (RRAM) devices. The three states have a conductivity ratio of 1:103 :107 , long retention over 10 000 s, and good endurance properties. The electrode area variation, impedance test, and current-voltage plotting show that the two resistance switches are attributable to the charge trap filling due to the effect of unscreened defect in 2D nanosheets and the formation of conductive filaments, respectively. This work paves way for stable perovskite multilevel RRAMs in ambient atmosphere. PMID- 29457378 TI - The use of antihypertensive fixed combinations in clinical practice needs a reappraisal. PMID- 29457376 TI - Delivery of Allogeneic Adipose Stem Cells in Polyethylene Glycol-Fibrin Hydrogels as an Adjunct to Meshed Autografts After Sharp Debridement of Deep Partial Thickness Burns. AB - Harvesting of autografts results in donor site morbidities and is limited in scenarios such as large total body surface area burns. In these instances, coverage is increased by meshing grafts at the expense of delayed biologic closure. Moreover, graft meshing increases the likelihood of contraction and hypertrophic scarring, limits range of motion, and worsens cosmesis. Many tissue engineering technologies have touted the promise of adipose-derived stem cells (ASCs) for burn wounds. The primary objective of the current study was to determine feasibility and efficacy of in situ ASC delivery via PEGylated fibrin (FPEG) hydrogels as adjuncts to meshed split thickness skin grafts in a porcine model. Deep partial thickness burns were created on the dorsum of anesthetized Yorkshire pigs, and subsequently debrided on post-burn day 4. After debridement, wounds were treated with: split thickness skin grafts (STSG); meshed STSG (mSTSG); and mSTSG + FPEG with increasing doses of ASCs. We show that FPEG hydrogels can be delivered in situ to prevent the contraction seen after meshing of STSG. Moreover, ASCs delivered in FPEG dose-dependently increase blood vessel size which significantly correlates with CD31 protein levels. The current study reports a dual-action adjunct therapy to autografting administered in situ, wherein FPEG acts as both scaffolding to prevent contraction, and as a delivery vehicle for ASCs to accelerate angiogenesis. This strategy may be used to incorporate other biologics for generating tissue engineered products aimed at improving wound healing and minimizing donor sites or scarring.

PMID- 29457379 TI - Levels of Cytokines and MicroRNAs in Individuals With Asymptomatic Hyperuricemia and Ultrasonographic Findings of Gout: A Bench-to-Bedside Approach. AB - OBJECTIVE: To assess potential associations among serum cytokines and microRNA (miR) levels with ultrasound (US) findings suggestive of urate deposits in chronic asymptomatic hyperuricemia and gout. METHODS: All participants underwent musculoskeletal US and measurements of serum interleukin-1beta (IL-1beta), IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12, IL-13, interferon-gamma, tumor necrosis factor, monocyte chemoattractant protein 1, and epithelial neutrophil-activating peptide 78, as well as miR-146a, miR-155, and miR-223 levels. RESULTS: Thirty individuals with asymptomatic hyperuricemia, 31 normouricemic controls, and 30 patients with gout were included. The frequency of synovitis and double contour sign using US was similar between asymptomatic hyperuricemia (67% and 27%, respectively) and patients with gout (77% and 27%, respectively), and each had a higher frequency than controls (45% and 0%, respectively). Serum IL-6 and IL-8 levels were similar between patients with asymptomatic hyperuricemia (mean +/- SD 69.7 +/- 73.4 and 18.5 +/- 25.6 pg/ml, respectively) and gout (mean +/- SD 75.8 +/- 47.6 and 24.4 +/- 31.7 pg/ml, respectively), and higher than controls (mean +/- SD 28.2 +/- 17.6 and 7.4 +/- 6.0 pg/ml, respectively). A similar distribution was observed for miR-155 levels in asymptomatic hyperuricemia, patients with gout, and controls (mean +/- SD 0.22 +/- 0.18, 0.20 +/- 0.14, and 0.08 +/- 0.04, respectively). Associations between morphostructural abnormalities suggestive of urate deposits (regardless of clinical diagnosis) and serum markers were assessed. Subjects with urate deposits had higher IL-6 (257.2 versus 47.0 pg/ml; P = 0.005), IL-8 (73.2 versus 12.0 pg/ml; P = 0.026), and miR-155 (0.21 versus 0.16; P = 0.015) levels than those without deposition findings. CONCLUSION: In individuals with chronic asymptomatic hyperuricemia, the presence of synovitis and double contour sign by US may represent a subclinical manifestation of monosodium urate crystal nucleation, capable of triggering inflammatory pathways (IL-6 and IL-8) and mechanisms of intercellular communication (miR-155), similar to what is observed in patients with gout. PMID- 29457380 TI - Two-Step Assembly of Thermoresponsive Gold Nanorods Coated with a Single Kind of Ligand. AB - Gold nanorods (GNRs) coated with a single kind of ligand show thermoreponsive two step assembly to provide a hierarchical structure. The GNRs (33 nm in length * 14 nm in diameter) coated with a hexa(ethylene glycol) (HEG) derivative form side-by side assemblies at 30 degrees C (TA1 ) as a steady state through dehydration. By further heating to over 40 degrees C (TA2 ), larger assemblies, which are composed of the side-by-side assembled units, are formed as hierarchical structures. The dehydration temperature of the HEG derivative varies depending on the free volume of the HEG unit, which corresponds to the curvature of the GNRs. Upon heating, dehydration first occurs from the ligands on the side portions with a lower curvature, and then from the ligands on the edge portions with a higher curvature. The different sized GNRs (33 * 8 and 54 * 15 nm) also show two-step assembly. Both the TA1 and TA2 are dependent on the diameter of the GNRs, but independent of their length. This result supports that the dehydration is dependent on the free volume, which corresponds to the curvature. Anisotropic assembly focusing on differences in curvature provides new guidelines for the fabrication of hierarchical structures. PMID- 29457381 TI - A Multicenter Study of the Validity and Reliability of Responses to Hand Cold Challenge as Measured by Laser Speckle Contrast Imaging and Thermography: Outcome Measures for Systemic Sclerosis-Related Raynaud's Phenomenon. AB - OBJECTIVE: Reliable and objective outcome measures to facilitate clinical trials of novel treatments for systemic sclerosis (SSc)-related Raynaud's phenomenon (RP) are badly needed. Laser speckle contrast imaging (LSCI) and thermography are noninvasive measures of perfusion that have shown excellent potential. This multicenter study was undertaken to determine the reliability and validity of a hand cold challenge protocol using LSCI, standard thermography, and low-cost cell phone/mobile phone thermography (henceforth referred to as mobile thermography) in patients with SSc-related RP. METHODS: Patients with RP secondary to SSc were recruited from 6 UK tertiary care centers. The patients underwent cold challenge on 2 consecutive days. Changes in cutaneous blood flow/skin temperature at each visit were imaged simultaneously using LSCI, standard thermography, and mobile thermography. Measurements included area under the curve (AUC) for reperfusion/rewarming and maximum blood flow rate/skin temperature after rewarming (MAX). Test-retest reliability was assessed using intraclass correlation coefficients (ICCs). Estimated latent correlations (estimated from multilevel models, taking values between -1 and 1; denoted as rho values) were used to assess the convergent validity of LSCI and thermography. RESULTS: In total, 159 patients (77% with limited cutaneous SSc) were recruited (84% female, median age 63.3 years). LSCI and standard thermography both had substantial reliability, with ICCs for the reperfusion/rewarming AUC of 0.67 (95% confidence interval [95% CI] 0.54, 0.76) and 0.68 (95% CI 0.58, 0.80), respectively, and ICCs for the MAX of 0.64 (95% CI 0.52, 0.75) and 0.72 (95% CI 0.64, 0.81), respectively. Very high latent correlations were present for the AUCs of LSCI and thermography (rho = 0.94; 95% CI 0.87, 1.00) and for the AUCs of standard and mobile thermography (rho = 0.98; 95% CI 0.94, 1.00). CONCLUSION: This is the first multicenter study to examine the reliability and validity of cold challenge using LSCI and thermography in patients with SSc-related RP. LSCI and thermography both demonstrated good potential as outcome measures. LSCI, standard thermography, and mobile thermography had very high convergent validity. PMID- 29457383 TI - Continuing Professional Development. PMID- 29457382 TI - An International Multispecialty Validation Study of the IgG4-Related Disease Responder Index. AB - OBJECTIVE: IgG4-related disease (IgG4-RD) can cause fibroinflammatory lesions in nearly any organ, leading to organ dysfunction and failure. The IgG4-RD Responder Index (RI) was developed to help investigators assess the efficacy of treatment in a structured manner. The aim of this study was to validate the RI in a multinational investigation. METHODS: The RI guides investigators through assessments of disease activity and damage in 25 domains, incorporating higher weights for disease manifestations that require urgent treatment or that worsen despite treatment. After a training exercise, investigators reviewed 12 written IgG4-RD vignettes based on real patients. Investigators calculated both an RI score as well as a physician's global assessment (PhGA) score for each vignette. In a longitudinal assessment, 3 investigators used the RI in 15 patients with newly active disease who were followed up over serial visits after treatment. We assessed interrater and intrarater reliability, precision, validity, and responsiveness. RESULTS: The 26 physician investigators included representatives from 6 specialties and 9 countries. The interrater and intrarater reliability of the RI was strong (0.89 and 0.69, respectively). Correlations (construct validity) between the RI and PhGA were high (Spearman's r = 0.9, P < 0.0001). The RI was sensitive to change (discriminant validity). Following treatment, there was significant improvement in the RI score (mean change 10.5 [95% confidence interval (95% CI) 5.4-12], P < 0.001), which correlated with the change in the PhGA. Urgent disease and damage were captured effectively. DISCUSSION: In this international, multispecialty study, we observed that the RI is a valid and reliable disease activity assessment tool that can be used to measure response to therapy.

AB - Up to now, surgical treatment of recurrent lateral patellar dislocation mainly includes: medial patellofemoral ligament reconstruction, tibial tubercle osteotomy, trochleoplasty, lateral retinacular release, derotation osteotomy and so on . Clinical reports show that: the use of a single or combined with several methods have achieved ideal short to mid-term clinical outcomes. However, there is no consolidate criterion concerning the choices of different kinds of surgical ways for the treatment of individual recurrent lateral patellar dislocation. Meanwhile, with the wide use of MPFL reconstruction and other surgical options, there are more and more complications and failures that are worthy and necessary for us to pay attention to, even though its high success rate. The aim of this article is to make a systematic review of the application status of different surgical methods, collecting the positive results we have achieved, illuminating application keys of surgical techniques, guiding patient-specific therapy more precisely. PMID- 29457386 TI - [Treatment of habitual dislocation of patella with reconstruction of medial patellofemoral ligament combined with release of lateral retinaculum and medial transfer and advancement of tibial tuberosity under arthroscopy]. AB - OBJECTIVE: To study clinical effects of triad operation including reconstruction of medial patellofemoral ligament, release of lateral retinaculum, Fulkerson tibial tubercle osteotomy, medial transfer and advancement under arthroscopy for the treatment of habitual dislocation of patella. METHODS: From March 2010 to May 2016, 35 patients with habitual patellar dislocation were treated with the triad operation, including 14 males, 21 females, ranging in age from 18 to 38 years old, with an average of 25.8 years old. Twelve patients had dislocations on the left knee, and 23 patients had dislocations on the right knee. The changes of Q angle, TT-TG value and Kujala score were compared before and after operation. RESULTS: All the patients were followed up, and the duration ranged from 9 to 35 months (mean, 23 months). The Q angle of male group was improved from preoperative (29.2+/-2.0) degrees to postoperative (14.8+/-1.2) degrees (P<0.05), and the Q angle of female group was improved from preoperative(30.6+/ 2.3) degrees to postoperative (16.7+/-1.5) degrees (P<0.05). CT showed that the TT-TG value was improved from preoperative (20.3+/-2.2) mm to postoperative (10.3+/-1.2) mm (P<0.05). The Kujala score was improved from preoperative 47.8+/ 7.5 to postoperative 88.4+/-6.2 (P<0.05). CONCLUSIONS: The triad operation including reconstruction of medial patellofemoral ligament, release of lateral retinacular, Fulkerson tibial tubercle osteotomy, medial transfer and advancement under arthroscopy for the treatment of habitual dislocation of patella has good short-term clinical effects. PMID- 29457387 TI - [Multi-point fixation with absorbable cartilage screws for the treatment of osteochondral fracture caused by patellar instability]. AB - OBJECTIVE: To study clinical effects of multi-point fixation with bioabsorbable cartilage screws for the treatment of osteochondral fracture caused by patellar instability. METHODS: During the period from August 2014 to Steptember 2016, there were 21 patients with osteochondral fracture caused by patellar dislocation, including 7 males and 14 females, ranging in age from 12 to 42 years old, with an average of 27 years old. During the operation, free fractures fragments of cartilage were found with a open surgery, and the patients were treated with fixation by absorbable cartilage screws combined with lateral retinaculum release and medial retinaculum shrinkage. The Lysholm scoring scale was used to evaluate the knee joint functions before and after operation. The retrospective study analyzing the data was carried out. RESULTS: All the patients underwent successful surgeries and were followed up with a mean period of 12 months(ranged, 8 to 22 months). The CT and X-ray examinations were performed after the operation which showed the fracture fragments were on good positon. The exercise level in all the patients basically returned to the pre-injury level. The postoperative Lysholm score was 86.11+/-4.97. CONCLUSIONS: The absorbable cartilage nail can effectively fix the free cartilage fragments of the osteochondral fracture due to the patellar instability, which is a simple operation, and worthy of clinical promotion. PMID- 29457388 TI - [Case-control study of therapeutic effects between extreme lateral interbody fusion and conventional posterior operation for the treatment of upper lumbar disc herniation]. AB - OBJECTIVE: To evaluate the clinical outcomes between extreme lateral interbody fusion and conventional posterior operation in the treatment of upper lumbar disc herniation. METHODS: Among 60 patients with upper lumbar disc herniation were treated with extreme lateral interbody fusion(XLIF) or conventional posterior operation from June 2010 to December 2014, 30 patients(19 males and 11 females) were treated with XLIF (XLIF group); and the other 30 patients(17 males and 13 females) were treated with conventional posterior operation (conventional group). In XLIF group, the lesions occurred at T12L1 segments in 2 patients, at L1,2 segments in 6 patients, at L2,3 segments in 10 patients, and at L3,4 segment in 12 patients. In conventional group, the lesions occurred at T12L1 segments in 1 patient, at L1,2 segments in 6 patients, at L2,3 segments in 8 patients, and at L3,4 segment in 15 patients. Operative incision lengths, time, blood loss, postoperative draining volume, hospital stays were recorded. Pre-and post operative visual analogue score(VAS) and Japanese Orthopedic Association(JOA) were compared between two groups. According to the image data, the intervertebral fusion device was observed to be displaced and the rate of interbody fusion was analyzed. RESULTS: All the patients were followed up, and the duration ranged from 12 to 48 months, with an average of 29 months. The complications included 2 femoral nerve damage in XLIF group (postoperative recovery within 3 months) and superficial incision infection in conventional group(cured by anti-infection). There were no patients with cerebrospinal fluid leakage(CSFL), cauda equina injuries or functional deterioration in the nerve root of lower limbs. In the XLIF group: the operative time was (65.6+/-20.5) minutes, blood loss was (48.8+/ 15.3) ml, postoperative draining volume was 0 ml. In the conventional group: the operative time was (135.2+/-33.9) minutes, blood loss was (260.3+/-125.7) ml, postoperative draining volume was (207.1+/-50.2) ml. The operative time, blood loss, postoperative draining volume in XLIF group were less than those in the conventional group(P<0.05). The JOA and VAS score were significantly improved in both groups during the follow-up period compared with those before operation(P<0.05). But the difference of the JOA and VAS score between the two groups 1, 6, and 24 months after surgery had not significant differences(P>0.05). There were no significant differences in the fusion rate between the two groups 6 and 12 months after operation(P>0.05). CONCLUSIONS: The XLIF fusion for the treatment of upper lumbar disc herniation has several advantages such as minimal invasive, stable vertebral plate, less complications and postoperative fusion rate, which has a better clinical effect. PMID- 29457389 TI - [Study on the risk factors for the misdiagnosis of femoral head osteonecrosis]. AB - OBJECTIVE: To evaluate the status and risk factors for the misdiagnosis of femoral head osteonecrosis, providing the basis for accurate diagnosis of osteonecrosis of femoral head. METHODS: The data of 314 hospitalized patients were collected from March 2015 to March 2016, and the risk factors for osteonecrosis of femoral head were analyzed by Logistic regression model. Misdiagnosis was defined that the diagnosis given on the first time was different from that on the second time or that given by expert group with the same symptoms and signs. The general data, predisposing factors, time of onset, hospital visits, clinical manifestations, X-ray film of hip joint, MRI and other data were statistically analyzed. RESULTS: Total 127 patients experienced misdiagnosis (up to 40.8%). Among them, the patients with osteonecrosis of femoral head misdiagnosed as other diseases accounted for 77.2% and the patients with other diseases misdiagnosed osteonecrosis of femoral head accounted for 22.8%. Statistical analysis showed that the predisposing factors, history of glucocorticoid and alcohol intake, diseased lower limb, pained lower limb, hidden disease attack, the level of first reception hospital and expert were significantly related with the misdiagnosis of femoral head osteonecrosis based on the logistic regression model (P<0.05) . The relationship between misdiagnosis and gender, age, primary disease taking glucocorticoid, approach and time of glucocorticoid use, the type of alcohol, drinking time had no statistical significance(P>0.05). The Logistic regression analysis showed that the hidden disease attack(OR=3.059) and level of first reception expert(OR=2.778) were the high risk factors associated with the misdiagnosis in which the femoral head necrosis was misdiagnosed as other diseases(P<0.01), and glucocorticoid intake history was the low risk factors(OR=0.387)(P<0.05). The Logistic regression analysis showed that the level of first reception expert (OR=3.573) was the high risk factor associated with the misdiagnosis in which the other diseases were misdiagnosed as necrosis of femoral head. CONCLUSIONS: Misdiagnosis rate of femoral head necrosis is high. Hidden disease attack and low level of first reception expert are the high risk factors associated with the misdiagnosis in which the femoral head necrosis was misdiagnosed as other diseases, however, glucocorticoid intake history is the protective factor of misdiagnosis. Low level of first reception expert is the high risk factor associated with the misdiagnosis in which other diseases were misdiagnosed as necrosis of femoral head.

AB - OBJECTIVE: To study the effects of surgical reconstruction of the lateral ligament complex for posterolateral rotatory instability (PLRI) of the elbow joint. METHODS: From January 2013 to January 2015, 20 patients with posterolateral rotatory instability of elbow joint were treated in our department. There were 12 males and 8 females whose age ranged from 30 to 60 years old, with an average age of 45.5 years old. Sixteen patients had injuries on the right side and 4 patients had injuries on the left side. Nine patients were caused by elbow dislocation and 6 cases were caused by elbow fracture. Five patients had no history of trauma. All the patients had closed injuries. According to the patient's history, physical examination and preoperative X-ray and MRI examination, a definite diagnosis was made. All the patients were treated conservatively for more than 2 months without efficacy, and they were treated with reconstruction of the lateral collateral ligament complex using palmaris longus tendon as a reconstruction graft under general anesthesia. Individual rehabilitation exercises were carried out according to the patient's condition. RESULTS: All the patients were followed up, and the duration ranged from 12 to 23 months(mean, 16 months). There were no complications such as infection and obvious limitation of elbow joint. The HSS score of all the patients was improved from preoperative 75.2+/-8.3 to postoperative 94.1+/-5.4; and the VAS score was improved from preoperative 6.7+/-3.2 to postoperative 2.3+/-1.5. CONCLUSIONS: The lateral cubital ligament complex is the most important limiting structure for the posterolateral rotatory instability of the elbow joint. Reconstruction of the lateral ligament complex is an effective method for the treatment of posterolateral rotatory instability of the elbow joint.

AB - OBJECTIVE: To investigate the influential factors of total blood loss during unilateral artificial total hip arthroplasty (THA). METHODS: From January 2014 to July 2016, 131 patients undergwent primary unilateral total hip arthroplasty, including 55 males and 76 females, ranging in age from 40 to 89 years old, with an average of 64.5 years old. The data of patients with unilateral total hip arthroplasty were collected, and the data of hemodynamics, coagulation function, hemoglobin and hematocrit values were recorded according to the observation data. The blood loss of the patients was calculated by Gross equation, and the data were analyzed by a statistical software. RESULTS: The total blood loss of the patients was significantly affected by the factors of pathogenesis and deep venous thrombosis of the lower limbs. The results were statistically significant(P<0.05). The gender, age, body mass index, prosthesis and anesthesia had little effects on the blood loss volume after replacement. CONCLUSIONS: The data in this study indicate that the volume of actual blood loss can be controlled by adjusting non-surgical factors such as gender, age, body mass index, prosthetic material, and risk factors, and surgical factors(postoperative complications, anesthesia). PMID- 29457392 TI - [Analysis on the occult blood loss after unicompartment knee arthroplasty]. AB - OBJECTIVE: To calculate the volume of occult blood loss after unicompartment knee arthroplasty(UKA), and analyze its influential factors by comparing with total knee arthroplasty. METHODS: A retrospective study of 130 cases from July 2012 to July 2015 were enrolled, of which and 65 cases were UKA, and 65 cases were TKA. In UKA group there were 27 males and 38 females, and the mean age was (62.3+/ 4.3) years old (ranged, 50 to 82 years old). There were 14 cases older than 70 years old, while 51 cases among 50 to 70 years old. The mean Body mass index (BMI) was (23.9+/-2.6) kg/m2(ranged, 18.3 to 30.1 kg/m2). In TKA group there were 23 males and 42 females, and the mean age was (67.4+/-4.9) years old (ranged, 57 to 81 years old). There were 34 cases older than 70 years old, while 31 cases among 50 to 70 years old. The mean BMI was (25.6+/-2.3) kg/m2(ranged, 20.6 to 33.1 kg/m2). Hidden blood loss was calculated according to Gross equation, and the differences between the two groups including different ages and genders were observed subsequently. The differences of red blood cell change between two groups were observed dynamically postoperatively. RESULTS: Postoperative hidden blood loss was (375.25+/-168.09) ml, HSS score was 87.11+/-5.39 in UKA group. Hidden blood loss was (898.81+/-221.47) ml, HSS score was 82.23+/-3.08 in TKA group. The differences between the two groups were significant. There were no significant differences in ages and genders. There were no significant relationship between hidden blood loss and HSS score or BMI, while the differences of red blood cell change were significant on the second day, the 4th day and the 5th day. There was no allogenic blood transfusion in UKA group, while 3 patients with transfusion in TKA group. CONCLUSIONS: Hidden blood loss is part of total blood loss after UKA, and the volume in UKA is less than that in TKA. It could be compensated by the body and rarely affect the knee function. The hidden blood is not a risk factor of transfusion. PMID- 29457393 TI - [Anatomical study on the reconstruction of the metacarpal bone with autogenous iliac crest grafting]. AB - OBJECTIVE: To explore the similarity between the iliac crest and the metacarpal bone, so as to provide an anatomical basis for the reconstruction of the metacarpal bone of the hand with the iliac crest grafting. METHODS: There are 16 upper limb specimens and 10 pelvic specimens. The morphological features of the second, third, fourth and 5th metacarpal bones and iliac crest were observed. The following indexes were measured: arc height and length of metacarpal head articular surface, volar-dorsal metacarpal diameter, ulnoradial diamater, arc height and length of iliac crest, and inner and outer diameter. The obtained data were statistically analyzed to compare the morphological, structural features, arc length and diameter length of each metacarpal bone and iliac crest. RESULTS: The arc length of the second metacarpal head, volar-dorsal metacarpal diameter, arc height, and the ulnoradial diameter are 22.040(21.425, 23.085) mm, (14.034+/ 0.465) mm, 4.185 (4.113, 4.598) mm, and (12.227+/-0.414) mm respectively. The arc length of the third metacarpal head, volar-dorsal metacarpal diameter, arc height, and the ulnoradial diameter are 23.430(22.743, 24.153)mm, (14.316+/ 0.430) mm, 4.235(4.170, 4.670) mm, and (12.382+/-0.425) mm respectively. The arc length of the fourth metacarpal head, volar-dorsal metacarpal diameter, arc height, and the ulnoradial diameter are 21.960 (21.245, 22.285) mm, (12.382+/ 0.288) mm, 4.125 (4.030, 4.305) mm, and (11.991+/-0.362) mm respectively. The arc length of the fifth metacarpal head, volar-dorsal metacarpal diameter, arc height, and the ulnoradial diameter are 20.030 (19.668, 20.148) mm, (11.807+/ 0.358) mm, 4.015(3.880, 4.205) mm, and (11.659+/-0.399) mm respectively. The inner and outer diameter of the iliac crest is 14.350 (13.660, 14.739) mm, and the arc length and height are (22.930+/-0.701) mm and (4.520+/-0.184) mm respectively. The difference between the volar-dorsal metacarpal diameter of the second metacarpal head and the inner and outer diameter of the iliac crest has no significant; while the volar-dorsal metacarpal diameter of the third, fourth and fifth metacarpal heads are apparently longer and shorter than the inner and outer diameter of the iliac crest, respectively. The differences are statistically significant. The differences between arc length of the iliac crest and arc length of the second, fourth and fifth metacarpl head are statistically significant. However, the difference of arc length between the third metacarpal head and the ilium, as well as the difference of arc height between the second and third metacarpal heads and the iliac crest have no statistical significances, while the arc height of the fourth and fifth metacarpal heads are obviously smaller than that of the iliac crest. CONCLUSIONS: Autologous iliac crest is similar with metacarpal bone in anatomy, which might be a suitable donor for metacarpal bone transplantation.

AB - OBJECTIVE: To evaluate the early clinical effects of suture anchor fixation for the treatment of avulsion fracture of tibial intercondylar eminence under arthroscopy. METHODS: From July 2012 to January 2015, 22 patients with the avulsion fracture of tibial intercondylar eminence were treated with arthroscopic suture anchor fixation. There were 12 males and 10 females, with an average age of 22.8 years old(ranged, 18 to 33 years old). Nine patients had the fractures in the right knee and 13 patients had the fractures in the left knee. The mean duration from injury to surgery was 6.8 days(ranged, 3 to 11 days). According to the improved Meyers-McKeever classification, 13 cases were type II, 7 cases were type III, and 2 cases were type IV. The clinical outcomes were evaluated by the range of motion, the Lysholm score, the IKDC 2000 subjective knee score, the axial shift test, and the anterior drawer test. RESULTS: All the incisions healed by first intention, and no complications occurred. All the patients were followed up, and the mean duration was 32.8 months (ranged, 18 to 42 months). The knee range of motion was improved from preoperative (49.37+/-7.69) degrees to (126.38+/-5.58) degrees at the latest follow-up(P<0.01). Lysholm score was improved from preoperative 43.4+/-5.6 to 79.2+/-6.2 at the latest follow up(P<0.01). And the IKDC 2000 score was improved from preoperative 52.6+/-6.2 to 81.4+/-5.7 at the latest follow-up(P<0.01). At the latest follow-up, the patient underwent physical examination. One patient had a positive result of axial shift test at the 18th month after operation with grade II laxity of anterior cruciate ligament. One patient had a weakly positive result of anterior drawer test at the 24th month after operation. CONCLUSIONS: Absorbable suture anchor fixation for the treatment of avulsion fracture of tibial intercondylar eminence under arthroscopy can provide accurate reduction and stable fixation, which can be applied to treat all types of fractures including comminuted fracture, and it is not necessary to remove the implant in the second operation. PMID- 29457395 TI - [Effects of patient-controlled infraclavicular brachial plexus block for postoperative pain and surgical efficacy in patients with terrible tyriad of the elbow]. AB - OBJECTIVE: To study the effects of ultrasound guided inter-scalene brachial plexus block and patient-controlled infraclavicular brachial plexus block for postoperative pain and surgical efficacy in patients with terrible tyriad of the elbow. METHODS: From March 2015 to August 2016, 60 patients with terrible tyriad of the elbows were treated in Ningbo No.6 Hospital with ASA I to II internal fixation. There were 32 males and 28 females, ranging in age from 16 to 70 years old, with a mean age of (55.6+/-18.2) years old. All the patients were divided into two groups(30 cases in each group): controlled intermuscular groove brachial plexus block (group C), infraclavicular brachial plexus block(group I). All catheters were placed using ultra-sound visualization and injected 0.33% ropivacaine 30 ml preoperatively. After regaining consciousness, all patients connected the electronic pump. The solution contained 0.2% ropiva-caine and the pump was setup to deliver a 5 ml bolus dose, with a 15 min lock out interval and background infusion at 5 ml/h. Both analgesia lasted until 5 d after operation. The patients underwent rehabilitation exercise everyday for 5 consecutive days starting from 24 h after operation.VAS score was recorded at 24 h, 48 h, 72 h and 4 d, 5 d after operation during rest and rehabilitation exercise time. The elbow articular range of motion and Mayo elbow performance score (MEPS) were recorded at 6 d after operation. Catheter-related adversereactions (such as oozing from the insertion site, obstruction, prolapse) were recorded. RESULTS: The success rate of blockade was 100% during insertion in both groups. Compared with group C, the VAS score at 3 d during rest time and 3, 4, 5 d after operation during rehabili-tation exercise were decreased(2.5+/-0.5 vs. 3.8+/-1.1, 3.0+/-0.4 vs. 5.0+/-0.9, 2.5+/-0.4 vs. 4.5+/-1.2, 2.1+/-0.3 vs. 4.1+/-1.0, P<0.05). The elbow articular range of motion and MEPS were increased(-2.19+/-18.01) degrees vs.( 8.19+/-12.16) degrees , (45.15+/-11.20) degrees vs. (22.15+/-7.02) degrees , (19.06+/-6.75) degrees vs. (9.10+/-2.48) degrees , (17.08+/-5.18) degrees vs. (10.12+/-3.15) degrees , (80.80+/-9.50) points vs. (64.90+/-11.21) points. The incidence of insertion site, obstruction, prolapse was 15, 5 and 10 cases respectively in group C, but without any catheter-related adverse reactions happened in group I (P<0.05). CONCLUSIONS: Patient-controlled infraclavieular brachial plexus block can be effectively used for postoperative pain after fixation for terrible tyriad of the elbows, and it can increase surgical outcome. PMID- 29457396 TI - [Ultrasonic analysis on the effect of strengthening exercise with strong tendon on lumbosacral multifidus muscles]. AB - OBJECTIVE: To study effects of strengthening exercise with strong tendon on the lumbosacral multifidus muscle. METHODS: Among 30 healthy volunteers, there were 21 males and 9 females, with an average age of(31.30+/-6.48) years old(ranged, 25 to 55 years old). The mean BMI was (21.70+/-1.95) kg/m2(ranged, 18.1 to 24.9 kg/m2). The ultrasonic image was used to analyze the thickness of lumbosacral multifidus(LM) under the follow conditions: supine position, and supine position with leg lifting 30 degrees , 60 degrees , 90 degrees ; seat and hip flexion, flexion to limit position, front to limit position with both hands climbing and strengthening the kidneys and the waist. RESULTS: The average lumbosacral multifidus thickness was (16.867+/-2.460) mm, (19.010+/-2.510) mm, (22.477+/ 2.220) mm, and(27.593+/-2.370) mm respectively in supine position with leg lifting 0 degrees , 30 degrees , 60 degrees , 90 degrees . There were statistical differences(F=423.619, P<0.05). The average lumbosacral multifidus thickness was (25.810+/-2.440) mm, (15.677+/-2.130) mm, and (15.533+/-2.110) mm respectively in seat and hip flexion, flexion to limit, front to limit positions with both hands climbing and strengthening the kidneys and the waist. There were statistical differences(F=597.789, P<0.05). CONCLUSIONS: When healthy volunteers in Shi's Orthopedics strengthen muscle exercises training, multifidus thickness is increased with the increasing of leg degree, reduced with the increasing of the flexion degree. It can change the stretching state of multifidus muscle by a specific training, so as to achieve the purpose of training the multifidus muscle. PMID- 29457397 TI - [Reconstruction of medial patellofemoral ligament with Tightrope button fixation on the femoral side for the treatment of traumatic patellar dislocation]. AB - OBJECTIVE: To explore the operating procedures and therapeutic effects of medial patellofemoral ligament reconstruction with Tightrope(Arthrex, FL, USA) button fixation at lateral femoral cortex. METHODS: From May 2014 to July 2016, 9 patients with traumatic patellar dislocation were treated. There were 5 males and 4 females, ranging in age from 16 to 47 years old, with an average of 23.7 years old. All the patients underment arthroscopic lateral retinaculum release and joint debridement first. Then the medial patellofemoral ligament was reconstructed by using a semitendinosus autograft. The ends of semitendinosus were pulled into two patellar tunnels respectively, knotted and fixed at the lateral side of patella. The semitendinosus loops were suspended and fixed through femoral tunnel with Tightrope button. The knee was fixed to about 60 degree and the tension of MPFL was adjusted by pulling Tightrope wire under arthroscopic observation. Two patients received superomedial transfer of tibial tuberosity on account of TT-TG >=20 mm. RESULTS: All the patients were followed up, and the duration ranged from 6 to 23 months, with an average of 13.6 months. Patellar stability was re-obtained in all patients. No dislocation re-currenced during the follow-up period. The Kujala score(scoring of patellofemoral disorders) was improved at the latest follow-up compared with that before operation. All the patients returned to routine life. CONCLUSIONS: Reconstruction of medial patellofemoral ligament with the Tightrope button fixation on the femoral side for the treatment of traumatic patellar dislocation is effective and economic. The method make the MPFL tension adjustable during the reconstuction under arthroscopy. The MPFL tension should be adjusted at 60 degree flexion of knee in order to avoid making tension level too high.

AB - OBJECTIVE: To explore the clinical outcomes of internal fixation or replacement for the treatment of radial head fractures through the extensor digitorum communis splitting approach. METHODS: From July 2012 to May 2015, 25 patients with radial head fractures were reviewed. There were 17 males and 8 females, ranging in age from 20 to 67 years old, with a mean age of 39 years old. Twenty one patients were treated with reconstruction of plate internal fixation, and 4 patients were treated with radial head replacement. According to Mason classification, 19 cases were type II and 6 cases were type III. All the patients underwent internal fixation or replacement through the extensor digitorum communis splitting approach. The patients were followed up clinically and radiographically until the beginning of fracture union and the entrance of function recovery of elbow motion into a plateau. The functional status of the elbow was evaluated using the Mayo Elbow Performance Index(MEPI). Radiographic signs of post-traumatic arthritis were rated according to the Broberg and Morrey system. RESULTS: All the patients were followed up, and the average duration was 29 months (ranged, 12 to 56 months). The average range of flexion and extension was 120 degrees , the extension was limited by 10 degrees , and the flexion was 135 degrees . The average forearm rotation range was 142 degrees , pronation was 75 degrees , supination was 67 degrees . The mean MEPI was 93+/-7(ranged, 80 to 100 scores); according to the MEPI scoring criceria, 19 patients got an excellent functional result, 6 good. According to the Broberg and Morrey systems of traumatic arthritis, 19 patients were in grade 0, 6 in grade 1, and no patients in grade 2 or 3. No patients with nonunion of the radial head and failure of internal fixation were found. There were no complications of nerve or vascular injuries, and obvious limitation of elbow rotation. Heterotopic ossification around the elbow occurred in 4 cases, but the motion was not significantly limited. There were no complications such as prosthesis loosening and infection in 4 cases after radial head prosthesis replacement. CONCLUSIONS: The extensor digitorum communis splitting approach is an effective exposure method for internal fixation or replacement in the treatment of radial head fractures.

AB - OBJECTIVE: To analyze clinical outcomes of osseous-bridge resection for the treatment of adult symptomatic talocalcaneal coalitions without arthritis. METHODS: The clinical data of 12 patients (15 feet) with symptomatic talocalcaneal coalitions without arthtitis from January 2013 to June 2016 were respectively analyzed. All cases were secondary talocalcaneal coalition. There were 9 males (11 feet) and 3 females (4 feet) with a mean (26.6+/-3.3) years old (ranged, 18 to 33 years old). According to the Rozansky classification, there were 4 (6 feet) type I, 3 (3 feet) type II, 2 (2 feet) type III, 1 (1 feet) type IV, and 2 (3 feet) type V. All patients received coalition resection and interposition of fat graft. Complication, recurrence and range of motion was regularly recorded after operation. Clinical efficacy was evaluated according to the visual analogue scale (VAS) and the American Orthopedic Foot and Ankle Society (AOFAS) ankle hindfoot scale. RESULTS: All patients were followed up for an average duration of (28.7+/-18.3) months (ranged, 12 to 48 months). All the incisions were primarily healed. There were no wound necrosis, infection, neurovascular or tendon injuries. Range of motion was improved in 13 feet. All patients returned back to work. Recurrence happened in 1 case 2 years after surgery, the patient received a secondary coalition resection. At the latest follow-up, VAS was 2.1+/-0.8 and AOFAS score was 82.7+/-7.2, were siginificantly improved when compared with the preoperative scores(8.2+/-0.7, t=6.233, P<0.01; 48.4+/-6.8, t=5.747, P<0.01). CONCLUSIONS: For adult patients with symptomatic talocalcaneal coalitions without arthritis, simple coalition resection could provide good clinical outcomes with minimal complications.

AB - OBJECTIVE: To study the clinical effects of negative pressure closed drainage combined with vancomycin loaded calcium sulfate and autogenous bone in the treatment of chronic osteomyelitis. METHODS: From June 2013 to December 2016, there were 35 cases of chronic osteomyelitis patients in our department, including 23 males and 12 females, ranging in age from 11 to 65 years old, with an average of 34 years old. The course of disease ranged from 8 to 46 months, with an average of 26 months. All patients were chronic osteomyelitis caused by open wounds. The lesions had recurrent redness and swelling and purulent skin perforation. Thirty-two patients had positive results in bacterial culture of sinus secretions, and 3 patients had negative results. Imaging examination showed the lesions of bone destruction, bone defects, surrounded by bone hyperplasia sclerosis. At the first stage, complete debridement was performed to remove necrotic tissues and inflammatory tissues; and the dressing of negative pressure closed drainage was used to completely cover the wound so as to promote the repair of the wound. At the second stage, the vancomycin loaded, calcium sulfate and autogenous iliac cancellous bone were mixed into the bone graft complex to evenly fill the lesions. The healing of the wound was observed and X-ray examination of the lesion was carried out to observe the absorption of calcium sulfate and the growth of new bone. RESULTS: Twenty-six patients underwent debridement and negative pressure closed drainage on time, 6 patients 2 times, and 3 patients 3 times. Thirty-two patients had incisions healed with grade A; 2 patients had incisions healed with grade B, and got completely healing after anti infection, and wound dressing treatment; 1 patient had an incision healed with grade C, and got normal healing after re-debridement at the 4th week after operation. All patients did not have skin redness and ulceration again. X-ray imaging showed that the implanted calcium sulphate was absorbed gradually around 4 weeks, new bone was formed at 8 weeks, and bone defects in the lesions area were healed completely at 6 months to 2 years. CONCLUSIONS: Negative pressure closed drainage combined with vancomycin loaded calcium sulfate and autogenous bone in the treatment of chronic osteomyelitis is a good and reliable method, worthy of clinical promotion.

AB - OBJECTIVE: To study clinical effects and safety of traditional manipulative reduction and percutaneous elastic intramedullary nail fixation for the treatment of proximal humeral fractures in children. METHODS: From October 2012 to May 2016, 65 patients with proximal humeral fractures were treated with traditional manipulative reduction and percutaneous elastic intramedullary nail fixation. There were 52 boys and 13 girls, ranging in age from 7 to 14 years old, with an average age of 11.2 years old. Twenty-three patients had injuries on the left side, and 42 patients had injuries on the right side. There were 13 cases of oblique fracture, 49 cases of transverse fracture, and 3 cases of comminuted fracture. All the patients had closed, obviously displaced fractures, without vascular and nerve injuries. The duration from injury to treatment ranged from 20 minutes to 5 days, with a mean of 3 days. The fracture healing and complications were observed after operation, and the curative effect was evaluated by Neer shoulder function score. RESULTS: The operation time ranged from 30 to 40 minutes, with a mean of 35 minutes; intraoperative blood loss ranged from 5 to 10 ml, with a mean of 6.5 ml. All the patients were followed up, and the duration ranged from 12 to 28 months, with an average of 18 months. All the fractures healed. According to the Neer evaluation system, 59 patients got an excellent result, 5 good and 1 fair. Four patients had a small amount of secretions on the tail of the needle; 2 patients had skin irritation; 1 patient had partial withdrawal of the nail, and the skin in all the patients healed after taking out the nail. No patients had nonunion fractures due to the broken nails and loosen screws, and no vascular or nerve injuries occurred. CONCLUSIONS: Traditional manipulative reduction and percutaneous elastic intramedullary nail fixation for the treatment of proximal humeral fractures in children has the advantages of less trauma, quicker recovery, less complications and simple operation. PMID- 29457404 TI - [Perioperative and drug management of patients with rheumatoid arthritis treated with joint replacement]. AB - Rheumatoid arthritis (RA) is a most common inflammatory joint disease with direct invasion of joint synovial membrane, cartilage and bone. Currently, although the RA mitigation drugs are being improved continously, but these drugs only can delay the development of joint dysfunction. Total hip arthroplasty or total knee arthroplasty(THA or TKA) has become the only choices for patients with advanced RA, and the joint function and deformity of the patients after surgical treatment can be improved to some extent. However, the progression of RA has a direct effect on the long-term clinical effect of the surgery, and how to improve perioperative management, and combine the joint replacement surgery and drug therapy effectively, have become the focus of attention in clinical doctors. This article intends to summarize the current situation of domestic and foreign management of usage of pre-operative drugs, operation skills, prosthesis selection, postoperative treatment, rehabilitation and complications, so as to improve the long-term efficacy of joint replacement.

AB - OBJECTIVE: To analyze and compare the efficacy of surgical approaches and fixations of anterolateral approach, lateral approach and posterolateral approach in treating posterolateral tibial plateau fracture. METHODS: A retrospective study of 44 cases from May 2010 to July 2014 were enrolled, of which there were 21 males and 23 females, and the mean age was 42.5 years old (ranged, 26 to 61 years). All the cases were divided into 3 groups according to the surgical approach, group A was anterolateral approach (19 cases), group B was lateral approach (15 cases), group C was posterolateral approach (10 cases). Operative time and bleeding volum were compared and the knee function was observed. RESULTS: The mean operative time of group A was (91.3+/-10.4) min, and the bleeding volum of which was (175.3+/-20.3) ml. The mean operative time of group B was(86.6+/-9.2) min, and the bleeding volum of which was(155.8+/-18.2) ml. The mean operative time of group C was (109.5+/-10.8) min, and the bleeding volum of which was(235.9+/-29.1) ml. There were significant differences in operative time and bleeding volum between group C and the other two groups(P<0.05). The mean follow-up time was 14.9 months (ranged, 10 to 35 months), and the HSS score of last follow-up was 89.6+/-7.5 (group A), 90.2+/-6.4(group B), 88.9+/-5.1 (group C). There were no significant differences in groups(P>0.05). CONCLUSIONS: The operative time of posterolateral approach was longer than anterolateral approach or lateral approach, as well as the bleeding volum which was higher in posterolateral approach, while no significant difference of the knee function was observed in these 3 different approaches.

AB - OBJECTIVE: To explore the clinical efficacy of double-plate fixation for the treatment of old tibial plateau fractures with Schatzker type IV through anterior midline and posteromedial approaches. METHODS: From July 2013 to July 2015, 15 patients with old tibial plateau fractures were treated with internal fixation using locking reconstructive plate for the posteromedial fragment and anatomical locking plate for anteromedial fragment through antero midline and posteromedial approaches. There were 9 males and 6 females, with an average age of 49.2 years old (ranged, 21 to 61 years old). Eight patients had injured in the left side and 7 in the right side. According to Schatzker classification, all patients were type IV. The mean interval from injury to operation was 26.5 days (ranged, 21 to 65 days). The main clinical symptoms before operation were knee joint swelling, pain, deformity and limitation of motion. The X-ray and CT confirmed the fracture type. The indexes such as tibial plateau tibial shaft angle (TPA), femoral tibial angle (FTA) and posterior slope angle (PSA) were compared between immediate postoperation and final follow-up using postoperative X-ray film. The knee functions were evaluated using the HSS (Hospital for Special Surgery) knee score system. RESULTS: Two patients had incision complications which healed by correct treatment, 1 patient had traumatic arthritis. All patients were followed up for mean 16.6 months (ranged, 13 to 24 months). No infections, deep venous thrombosis, implant loosening and breakage, fragment displacement, plateau surface collapse and bone nonunion found. The bone union time ranged from 3 to 8 months (mean 6.07 months) after operation. The average immediate postoperative value of TPA, FTA and PSA were(86.81+/-1.67) degrees , (168.00+/-3.29) degrees and(10.20+/-1.47) degrees respectively; and(86.47+/-1.67) degrees , (168.53+/ 3.03) degrees and (10.54+/-1.21) degrees respectively at the final follow-up evaluation, showing no statistical differences(P>0.05). According to the HSS score system, 26.33+/-3.86 in pain, 20.00+/-1.79 in function, 16.00+/-1.55 in range of motion, 8.67+/-0.94 in muscle strength, 8.53+/-1.67 in flexion deformity, 9.33+/-0.94 in joint stability, and the total mean score was 88.86+/ 8.92. The outcomes were excellent in 10 cases, good in 4, and fair in 1. CONCLUSIONS: Double-plate fixation via combined anterior midline and posteromedial approaches is an ideal surgical method for old tibial plateau fractures with Schatzker IV type, showing satisfactory exposure, reliable reduction and fixation, and benefiting for early functional exercise. The short term clinical results was satisfactory. PMID- 29457409 TI - [Analysis of risk factors of infection for complex tibial plateau fractures after operation]. AB - OBJECTIVE: To analyze the risk factor of infection for complex tibial plateau fractures after operation. METHODS: Totally clinical data of 293 patients with complex tibial plateau fractures underwent open reduction and internal fixation were retrospectively analyzed from September 2010 to March 2015, including 199 males and 94 females, ranging in age from 17 to 80 years old with an average of 47.3 years old. The possible risk factors such as gender, age, smoking, diabetes, type of fracture(open/closed), classification of open fracture(Gustilo-Anderson classification), classification of soft tissue injury in closed fracture (Tscherne-Gotzen classification), fracture classification(Schatzker V/VI), osteofascial compartment syndrome, ASA score, anesthesia, timing of surgery, operative time(<=150 min/>150 min), surgical approach, combined approach or not, internal fixation site were studied. The multivariate Logistic regression model was used to analyze the risk factors. RESULTS: Twelve patients were infected of all 293 patients after operation, the infection rate was 4.10%. Univariate analysis showed that fracture type(chi 2 =14.496, P=0.001), fracture classification(chi2=4.560, P=0.033), osteofascial compartment syndrome(chi2=15.631, P=0.001), operative time(chi2=11.233, P=0.001) were correlated with complex tibial plateau fractures postoperative infection. Multivariate analysis showed that open fractures(chi2=9.696, P=0.002) and osteofascial compartment syndrome(chi2=9.119, P=0.003) were complex tibial plateau fracture risk factors for infection after operation. CONCLUSIONS: Open fractures and osteofascial compartment syndrome are risk factor of complex tibial plateau fracture for infection after operation. While through debridement for open fracture patients, early diagnosis and promt treatment for osteofascial compartment syndrome could reduce incidence of infection. PMID- 29457411 TI - [Effect of hip fracture at different sites in elderly patients on prognosis]. AB - OBJECTIVE: To determine the effect of site of fracture on the prognosis for patients of elderly hip fracture. METHODS: From January 2012 to December 2014, 667 patients with hip fractures were divided into femoral neck fracture group and intertrochanteric fracture group according to the site of fracture. There were 304 cases of intertrochanteric fracture, including 96 males and 208 females, with an average age of (80.33+/-7.94) years old. There were 217 cases of femoral neck fracture, including 74 males and 143 females, with an average age of (79.82+/ 9.33) years old. Patients' data, mortality and activities of daily living were compared between two groups. RESULTS: There were no significant differences in age, gender, comorbidity, ASA classification, and anesthesia between two groups, but the time of admission to surgery, duration of operation, blood loss of intra operative, volume of drainage, and the average of transfusion were shown to have significant differences. The levels of White blood cell count (WBC) for intertrochanteric fracture group were shown to be higher than that of femoral neck fracture patients at admission, 1, 3 and 5 days after operation. The levels of hemoglobin, and albumin for intertrochanteric fracture were lower than that of femoral neck fracture patients at all period of time. The mortality of intertrochanteric fracture group during hospitalization, 1, 3, 6, and 12 months were higher than that of femoral neck fracture, but did not reach significant difference. In patients who survived, the scores of ADL for femoral neck fracture were higher than that of intertrochanteric fracture at discharge, 1, 3 months after operation, but there was no significant difference for ADL at 6 and 12 months between two groups. CONCLUSIONS: The response of stress for intertrochanteric fracture were more than femoral neck fracture, but the mortality was similar than that of femoral neck fracture after excluding the influence of age, sex, comorbidity, and other factors. Compared to intertrochanteric fracture, the femoral neck fracture patients had a better functional recovery during early stage, and the two groups reached a similar functional recovery at 1 year after operation. PMID- 29457410 TI - [Effect of admission blood urea and creatinine levels on mortality in elderly patients with hip fracture]. AB - OBJECTIVE: To observe the effect of admission blood urea and creatinine levels on mortality in elderly patients with hip fracture. METHODS: Form January 2013 to December 2014, 767 elder patients with hip fracture were treated in our hospital including 253 males and 514 females, aged from 65 to 96 years old with an average of(75.67+/-6.81) years old. According blood urea and creatinine levels, the 767 hip fracture patients were divided into four groups as follow: group A(blood urea>=5 mmol/L, creatinine>=70 MUmol/L); group B (blood urea>=5 mmol/L, creatinine<70 MUmol/L); group C (blood urea<5 mmol/L, creatinine>=70 MUmol/L); group D(blood urea<5 mmol/L, creatinine<70 MUmol/L). In group A, there were 211 patients including 70 males and 141 females, aged from 65 to 95 years old with an average of(80.24+/-6.51) years old; in group B, there were 355 patients including 125 males and 230 females, aged from 65 to 93 years old with an average of(78.46+/-7.09) years old; in group C, there were 36 patients including 11 males and 25 females, aged from 65 to 95 years old with an average of (77.83+/-6.78) years old; in group D, there were 165 patients including 47 males and 118 females, aged from 65 to 96 years old with an average of (76.71+/-8.35) years old. The survivals and dead patients in four groups were collected and in hospital mortality rate, 3-month, 12-month and 18-month mortality rate of patients were calculated. COX regression analysis was performed on these data, and clinical significance of serum urea and creatinine at admission in the elderly patients was researched. RESULTS: All 767 hip fracture patients were followed up from 18 to 24 months with an average of (21.33+/-1.25) months, 159 patients were died in follow up period. The in-hospital mortality rate in 3 month, 12-month and 18-month mortality rate of the patients with high blood urea and high blood creatinine (urea>=5 mmol/L, creatinine>=70 MUmol/L) were 2.37%, 9.95%, 16.11% and 26.07%, and were higher than other three groups respectively. COX regression analysis revealed that the independent predictors effecting the mortality rate included age [P=0.000, OR=1.375, 95%CI(1.155, 1.637)], blood urea at admission [P=0.000, OR=1.375, 95%CI(1.155, 1.637)], and blood creatinine at admission[P=0.037, OR=1.213, 95%CI(1.121, 1.484)]. CONCLUSIONS: Elderly hip fracture patients with high serum urea and high serum creatinine at admission indicate higher fatality rate. Age, serum urea and serum creatinine at admission were independent predictors of fatality rate of elderly hip fracture patients.

AB - OBJECTIVE: To evaluate the efficacy and advantages of personalized 3D printing guided template of lateral superior ramous of pubic intramedullary lag screw. METHODS: From July 2015 to December 2016, 20 patients with the superior and inferior ramous of pubis fracture were treated with lag screws placement. All the patients were divided into test group(with guided template) and control group(with general operation). There were 7 males and 3 females with an average age of (46.20+/-3.03) years old in test group and 6 males and 4 males with (48.50+/-2.25) years old in control group. There were 6 cases and 5 cases of superior and inferior branches fractures of pubic on the left side and 4 cases and 5 cases on the right side in two groups respectively. The operation time, perspective times and bleeding loss were compared between two groups. RESULTS: The test group and the control group had no statistically significant relative to gender, age, fracture classification. The average time of surgery, average intraoperative fluoroscopy times, mean blood loss in test group were (31.0+/-5.3) min, (3.5+/-2.1) times, (75.6+/-10.5) ml respectively, and in control group were(55.0+/-6.8) min, (27.6+/-3.2) times, (85.5+/-12.5) ml respectively. There were significant Statistical differences between two groups(P<0.05) in average operation time and average fluoroscopy times, however, mean blood loss had no significant differences between two groups(P>0.05). CONCLUSIONS: The personalized guide template based on 3D printing technology could realize precise placement of the lateral intramedullary lag screw fixation in the superior branch of pubic, also could save the operation time and reduce the times of radiation exposure of patients and surgeons.

AB - OBJECTIVE: To explore the curative effect and the recessive loss of blooding of PFNA for the treatment of intertrochanteric fractures of femur. METHODS: From January 2012 to January 2015, a total of 49 patients with intertrochanteric fractures of femur were treated with proximal femoral anti-rotation nail including 41 males and 8 females with an average age of 79 years old ranging from 65 to 91 years old. According to the modified Evans type, 1 case was type I, 12 cases were type II, 36 cases were type III. All cases were fresh fractures. Patients had hip pain, movement limited, joint swelling, bruising, extorsion deformity, X-ray and CT examination showed completely fractures. All patients were treated by closed reduction and PFNA internal fixation. Three comminuted fractures using closed reduction were not satisfied, then were treated by limited PFNA fixation after open reduction. RESULTS: The patients' incision got the grade A healing, no complications such as infection and internal fixation failure happened. All patients were followed up from 6 to 36 months (means 22 months). The pain VAS score decreased from preoperative 7.70+/-1.97 to 1.00+/-0.26 at 6 months after operation(P<0.01). Harris hip score improved from preoperative 8.70+/-4.19 to 91.70+/-5.31 at 6 months after operation(P<0.01). The outcome at 6 months after operation was excellent in 34 cases, good in 7, poor in 1. The fracture healing time was from 8 to 16 weeks with an average of 12 weeks after operation. One patient with osteoporosis, crushing broken, poor compliance, associated with schizophrenia at the same time, appeared with the displacement of the femoral greater trochanter, with conservative treatment for healing. CONCLUSIONS: Intertrochanteric fractures of femur are common in the elderly trauma, in pain relief, recovery of hip function, to provide quality of life for the patients, PFNA achieved satisfactory effect, but its existence is worth to pay close attention to the recessive loss of blood. PMID- 29457414 TI - [Clinical research of popliteal cyst excision combined with debridement of the knee under arthroscopy with local anesthesia]. AB - OBJECTIVE: To evaluate the clinical effects of popliteal cyst excision combined with debridement of the knee under arthroscopy with local anesthesia. METHODS: From February 2009 to August 2014, 52 patients with popliteal cysts were treated in our hospital, including 34 males and 18 females with an average age of 43.6 years old ranging from 14 to 62 years old; 29 cases were on the right knee and 23 on the left knee. Preoperative diagnosis was performed according to MRI findings and to determine whether other knee disorders were associated with the disease, 52 patients were diagnosed as popliteal cyst before operation; 23 cases of simple meniscus injury or cartilage injury, 18 cases of osteoarthritis, 7 cases of cruciate ligament injury, 2 cases of gouty arthritis, 1 case of rheumatoid arthritis, 1 case of pigmented villonodular arthritis. The preoperative clinical manifestations involved knee swelling in 21 cases, knee joint pain in 16 cases, joint lock in 8 cases, leg weakness in 4 cases, and knee joint snapping in 4 cases. Cyst size was 4.0 cm* 3.3 cm to 6.2 cm* 5.3 cm. According to the Rauschning and Lindgren standards, 1 case was grade I, 9 cases were grade II, 42 cases were class III. The rehabilitation plan should be made according to the patient's specific injuries and intraoperative management. During the postoperative follow-up, the postoperative curative effect was evaluated by the standard grading of Rauschning and Lindgren of popliteal cyst. RESULTS: All the incisions healed by first intention, and no complications occurred. All the cases were followed up from 25 to 64 months (averaged 39.6 months). For the Rauschning and Lindgren grading, 43 cases were grade 0, 8 cases were grade I, 1 case were grade II. CONCLUSIONS: Local anesthesia under arthroscopy and popliteal cyst removal knee joint cavity debridement is effective, less trauma, quick recovery, short term effect is good. The recurrence rate is also low because of the primary disease of the knee joint is also treated. After the operation, the rehabilitation plan should be made according to the intraoperative treatment and actively trained so as to recover at an early date.

AB - OBJECTIVE: To study the effect of Bushen Huoxue decoction on calcification of cartilage endplate in lumbar vertebrae. METHODS: Six healthy male gerbils with 2 month-old were selected as normal control group, and 24 7-month-old healthy male gerbils were fed to 12-month-old to establish the aged gerbil model. Thirty gerbils were randomly divided into five groups as follow: the normal control group (n=6), model group (n=6, normal saline 4 ml/kg, intragastric 30 d), Bushen Huoxue low dose group(n=6, 1.9* 10- 3 ml/g given Bushen Huoxue recipe orally, 30 d), Bushen Huoxue middle dose group(n=6, 3.8* 10- 3 ml/g given Bushen Huoxue recipe orally, 30 d), Bushen Huoxue high dose group(n=6, 7.6* 10- 3 ml/g given Bushen Huoxue recipe orally, 30 d), the intervention group administered for 1.36 g from 7-month-old age, 30 d. The animals were sacrificed at the age of 2 months in the normal control group and 12 months of age in the other groups. The morphology of the lumbar vertebral cartilage endplate, the area of vascular bud, the ratio of non-calcified/calcified layer were analysis by HE chromosome visual method. The expression of type X collagen and BMPs in cartilage endplates were detected by rabbit monoclonal immunohistochemical staining. RESULTS: The relative area of the vascular buds cartilage endplate measurements showed that compared with the model group, middle dose group and normal control group increased (P<0.05), high and low dose groups all had different degrees of increase, but no statistical significance(P>0.05). The ratio of cartilage endplate thickness of non-calcified/calcified showed that compared with the model group, Bushen Huoxue middle dose, normal control group increased, with statistical significance(P<0.05), and high and low dose groups all had different degrees of increase, but there were no statistical significance(P>0.05). Compared with the model group, the expression of type X collagen in the cartilage endplate of the normal group, the Bushen Huoxue low, middle and high dose groups decreased, and had statistical significance(P<0.01); compared with the model group, the expression of BMPs in the normal group, Bushen Huoxue middle dose group increased, with statistically significant(P<0.01), while the high and low dose groups increased in different degrees, but there was no statistical significance(P>0.05). CONCLUSIONS: Bushen Huoxue prescription can delay the calcification of cartilage endplate in the process of aging, suggesting that it can be used as a preventive medicine for early disc degeneration. PMID- 29457416 TI - [Meta-analysis of the efficacy and safety of PFNA and InterTAN for the treatment of intertrochanteric fractures]. AB - OBJECTIVE: To system evaluate the clinical effect and safety of PFNA and InterTAN internal fixation methods for femoral intertrochanteric fracture. METHODS: According to the Cochrane systemic analysis method, randomized controlled trials and quasi-randomized controlled trials which were about the comparison of PFNA and InterTAN for intertrochanteric fracture were collected from Cochrane Library(2017, issue 4), PubMed (January, 2003-May, 2017), Wanfang Med Online (January, 2003-May, 2017) and China Academic Journals Full-text Database(January, 2003-May, 2017) by computer searching. Cross-checking was done after assessing the quality of the included trials and extracting the data by two reviewers independently. Data analysis were performed with RevMan 5.3. RESULTS: Two randomized controlled trials and five quasi-randomized controlled trials involving 611 cases met the inclusion criteria. The meta-analyses showed no significant differences between the two methods on Harris scores[MD=-1.00, 95%CI( 2.29, 0.28), P=0.13], union time[MD=0.04, 95%CI (-0.70, 0.77), P=0.92], full weight-bearing time[MD=1.06, 95%CI(-0.29, 2.42), P=0.13], hospital stay[MD=-0.04, 95%CI (-0.52, 0.45), P=0.89] and length of incision[MD=-1.00, 95%CI (-2.64, 0.65), P=0.23]. There were significant differences between the two methods on operative time[MD=-25.75, 95%CI (-37.47, -14.03), P<0.000 1], intraoperative blood loss[MD=-55.67, 95%CI(-108.07, -3.27), P=0.04] and the internal fixation complication rate[MD=4.17, 95%CI (1.33, 13.08), P=0.01]. CONCLUSIONS: Both PFNA and InterTAN could provide good effect for intertrochanteric fracture. The operation time of PFNA is shorter than that of InterTAN, and there is less blood loss during operation. PFNA may be the first choice for the treatment of patients who have many complications and can't endure long-time operation. The complications of PFNA are more than those of InterTAN. In patients with long life expectancy and high requirements, InterTAN may be preferentially selected to reduce complications. According to the patient's situation, after a comprehensive consideration, appropriate treatment can be selected. PMID- 29457417 TI - [Clinical observation of the second operation for refracture after internal fixation of clavicle]. AB - OBJECTIVE: To evaluate the outcome of Titanium Elastic intramedullary nailing(TEN) for the treatment of refracture of clavicle. METHODS: From March 2010 to March 2016, 9 cases of clavicle fracture, postoperative re-fracture (plate broken before fracture healing, plate and screw pull out or refracture after fracture union and internal fixation removal) included 6 males and 3 females with a mean age of 38.6 years old ranging from 20 to 62 years old; 3 cases were sports injury, 5 cases were traffic injury, 1 case was severe injury. All cases were closed fractures, and 2 cases were multiple fractures. According to OTA(Orthopaedic Trauma Association classification), 2 cases were 06-A1, 1 case was 06-A2, 1 case was 06-A3, 2 cases were 06-B1, 2 cases were 06-B2, and 1 case was 06-B3. Among them, 4 cases were treated with AO titanium elastic intramedullary nail (TEN), and 5 cases of early internal fixation failure of clavicle fracture were treated with plate and screw internal fixation plus bone graft. The time of bone union, VAS score and Constant Shoulder Score were observed and recorded. RESULTS: All incisions healed at stage I without infection. All 9 patients were followed up for a period of 14 months. All patients' implants were removed at 12 months after the second operation without refractures. The Constant score of shoulder joint was from 64 to 94 at 4 weeks after the second operation, 91 to 100 at 4 weeks after implants removal. The average bone healing time was 4.3 months from 3 to 6 months. The pain VAS score decreased significantly and the pain was relieved significantly. CONCLUSIONS: Titanium elastic intramedullary nail (TEN) for the treatment of clavicle fracture after internal fixation of refracture patients can be achieved better outcomes, less trauma, good fracture healing, good postoperative recovery of shoulder joint function, but need to pay attention to the reasonable selection of patients. PMID- 29457418 TI - [Outcomes and complications of Tightrope button plate for repairing acromioclavicular dislocation]. AB - OBJECTIVE: To study the clinical outcome and complications of Tightrope button plate for repairing acromioclavicular dislocation of Rockwood type III to V. METHODS: From May 2014 to December 2016, 17 patients with acromioclavicular dislocation of type III-V were treated with Tightrope button plate including 10 males and 7 females with an average age 39.8 years old ranging from 20 to 68 years old. Four patients were treated with arthroscopy and 17 patients were treated with mini-invasive by X-ray assisted. Shoulder function, X-ray and complications after operation were assessed. RESULTS: All patients were followed up for 5 to 23 months with a mean of 10.8 months. All patients got satisfying reduction immediately postoperatively. Among them, 1 case of clavicle end wound foreign body reaction, rupture, effusion, healing after the second suture; 1 case of foreign body granuloma formation at the end of clavicle were resected and removed at 4 months after operation; 3 cases loss reduction(less than 50% of acromioclavicular joint). No coracoid fracture and suture breakage observed. The shoulder mobility was restored in 15 cases at 4 to 6 weeks postoperatively, and the shoulder adhesion in 2 cases was delayed to 5 to 7 months after operation. The Constant scores were improved from 46.9+/-6.0 preoperatively to 92.7+/-4.0 at the final follow-up. X-ray evaluation of postoperative coracoclavicular tunnel location, patients' coracoclavicular tunnel with mini-invasive fluoroscopy all closed to the ideal position (across the clavicle vertically through the coracoid base center), while different degree of tunnel position deviation were observed in arthroscopic patients. CONCLUSIONS: Tightrope button plate for the treatment of acromioclavicular joint dislocation had advantages of minimally invasive, effective, good clinical results, the majority of common complications does not affect efficacy. Small incision X-ray method can provide more satisfactory and reliable tunnel location.

AB - Dislocation of proximal tibiofibular joint(PTFJ) is relatively infrequent in clinic, it can be either isolated or associated with tibia fracture, fibular fracture and ankle injury and so on. Chronic symptomatic PTFJ instability are easily mixed with meniscal tears. It was easily neglected because of the mild clinical presentation and atypical change on radiography. Early diagnosis and treatment are crucial to prevent chronic knee pain and instability. The paper concluded the anatomy, classification, complication, diagnosis, treatment, clinical effect and insufficient of the dislocation of PTFJ, to direct the diagnosis and treatment of proximal tibiofibular joint dislocation in clinical work. PMID- 29457425 TI - [Progress on research of Madelung's deformity]. AB - Madelung deformity is a rare deformity of forearm and wrist caused by growth disorders of distal radius ulnar and palmar epiphyseal. Current studies showed that its incidence mainly associated with trauma, epiphyseal developmental abnormalities, nutritional disorders and genetic deletion or mutation. The early clinical presentation is not typical, in middle and late time, wrist deformity and weak can appear. Plain film considered as the main means of diagnosis is often lack of early diagnosis significance. Although wrist joint magnetic resonance imaging showing early soft tissue and skeletal abnormalities were used for the early diagnosis of the disease, current domestic study in magnetic resonance imaging of this deformity is less. According to the size of the distal ulnar inclination angle and palm angle, this deformity can be divided into different types. The patients with severe deformity and symptoms usually need surgical intervention including ulna revision and osteotomy of the distal radius at present. Although the two operation can achieve good clinical results, the surgical trauma, infection and postoperative risk of joint activities are more.

AB - OBJECTIVE: To compare efficacy and safety of minimally invasive sinus tarsal approach versus conventional L-shaped lateral approach in treating calcaneal fractures. METHODS: The studies concerning about randomized controlled trial and non-randomized controlled trial of minimally invasive sinus tarsal approach versus conventional L-shaped lateral approach in treating calcaneal fractures from the time of creating database to March, 2017 were searched from PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), EMbase, ISI Web of Knowledge databases, VIP, CNKI, CBM and Wan Fang. The literatures which screened by randomized controlled trial and non- randomized controlled trial were extracted and performed quality assessment by two people. Meta analysis were performed by RevMan 5.3 software and GRADE system were used to evaluate quality. RESULTS: Four randomized controlled trial and 4 non-randomized controlled trial were included, totally 493 patients. Meta-analysis results showed compared with conventional L-shaped lateral approach, minimally invasive sinus tarsal approach had shorter operative time [MD=-5.41, 95%CI(-6.71, -4.12), P<0.000 01], lower incidence of postoperative complications[OR=0.10, 95%CI(0.05, 0.21), P<0.000 01], and higher AOFAS score [MD=-3.09, 95%CI(-1.72, 4.46), P<0.000 01] at the final follow-up. Bohler angle in conventional L-shaped lateral approach was better than that of minimally invasive sinus tarsal approach [MD=-0.80, 95%CI(-1.45, -0.14), P<0.05]. While there were no significant differences in postoperative Gissanes angle [MD=0.35, 95%CI(-0.77, 1.47), P>0.05] and Maryland score[MD=2.12, 95%CI( 0.71, 4.95), P>0.05] between two groups. CONCLUSIONS: Minimally invasive sinus tarsal approach and conventional L-shaped lateral approach has similar clinical effect for the treatment of calcaneal fractures. However, minimally invasive sinus tarsal approach has advantages of shorter operation time, lower incidence of complication and better safety. For the limited quantity of the original studies, operative approach should be chosen according to the patient.

METHODS: CT and MRI data of 23 patients with primary spinal large B cell lymphoma confirmed by histopathology were retrospectively analyzed from March 2011 to August 2015. Among them, including 14 males and 9 females aged from 28 to 70 years old with an average of 53.4 years old. The clinical manifestation mainly focus on pain around spinal and minority peripheral nerve symptom. The courses of disease ranged from 2 weeks to 3 months with an average of 9 weeks. Nine patients underwent CT plain scan, 8 patients underwent plain and enhanced CT; 21 patients underwent MRI plain scan and enhanced; 15 patients underwent CT and MRI examination. The location, bone changes, shape, density, signal intensity and enhancement characteristics of lesions were observed and compared with pathology. RESULTS: Location and size of lesion showed cervical vertebrae in 1 case, thoracic vertebrae in 16 cases, lumbar vertebrae in 2 cases, and sacral vertebrae in 4 cases. Mass was larger, the largest cross-sectional size of group was up to 73 mm* 125 mm. CT examination showed that 11 cases with "cloud and mist" shape change, 6 cases with compression fractures, and with "floating ice" shape change, 9 cases with "oversleeve" shape change, 11 cases with spinal stenosis; enhancement scan showed obvious reinforcement. MRI showed slightly low signal on T1WI and T2WI were slightly high signal, and signal was uneven, and enhancement scan showed obvious reinforcement, 13 of 16 cases with spinal canal stenosis changed like "oversleeve", intervertebral space showed no significant stenosis. Comparison of CT and MRI showed the manifestation of bone destruction by CT was superior than that of MRI, but the range of lesion, and related surrounding structures were not better than MRI. MRI displayed the range of lesion usually bigger than CT. Pathology results showed that 23 patients were all primary spinal large B cell lymphoma. CONCLUSIONS: Primary spinal large B cell lymphoma has certain features in age, location and imaging findings. The "cloud and mist", "floating ice" and "oversleeve" shape bony destruction by CT and MRI has certain significance to diagnosis of primary spinal large B cell lymphoma.

PMID- 29457441 TI - [A case report of aged radius plasticity bend]. PMID- 29457442 TI - [Development and application of artificial vertebral body]. AB - Artificial vertebral body has achieved good results in treating spinal tumors, tuberculosis, fracture and other diseases. Currently, artificial vertebral body with variety of kinds and pros and cons, is generally divided into two types: fusion type and movable type. The former according to whether the height could be adjusted and strength of self-stability is divided into three types: support fixed type, adjust-fixed type and self-fixed type. Whether the height of self fixed type could be adjusted is dependent on structure of collar thread rotation. The latter is due to mobile device of ball-and-socket joints or hollow structures instead of the disc which retains the activity of the spine to some extent. Materials of artificial vertebral body include metals, ceramics, biomaterials, polymer composites and other materials. Titanium with a dominant role in the metal has developed to the third generation, but there are still defects such as poor surface bioactivity; ceramics with the representative of hydroxyapatite composite, magnetic bioceramics, polycrystalline alumina ceramics and so on, which have the defects of processing complex and uneven mechanical properties; biological material is mainly dominated by xenogeneic bone, which is closest to human bone in structure and properties, but has defects of low toughness and complex production; polymer composites according to biological characteristics in general consists of biodegradable type and non-biodegradable type which are respectively represented by poly-lactide and polyethylene, each with advantages and disadvantages. Although the design and materials of prosthesis have made great progress, it is difficult to fully meet requirements of spinal implants and they need be further optimized. 3D printing technology makes process of the complex structure of prosthesis and individual customization possible and has broad development prospects. However, long production cycles and high cost of defect should be overcome. Although artificial vertebral body has achieved curative effect in treating spinal disease, there were reports of implant loosening or displacement. Combining with evaluation standards not unified, short follow-up time, its exact effect needs further observation. PMID- 29457443 TI - [Diagnosis and treatment of esophagustype cervical spondylosis]. AB - Esophagustype cervical spondylosis is easily misdiagnosed or missed diagnosed for its lower incidence. The pathological basis manily concerned with compression of osteophyte for esophageal and tracheal wall and local inflammatory reaction. The diagnosis of disease is generally not difficult. Especially dynamic esophagogram could not only show degree of cervical degeneration and osteophyte shape, but also could clearly observe location and degree of osteophytosis indenting esophageal and tracheal. Recently, the treatment of esophagustype cervical spondylosis has been the focus of attention. It is generally believed that conservative treatment could alleviate disease but could not cure it. More and more scholars tend to treat disease by surgical resection of osteophyte to relieve compression for esophagus, and clinical symptoms could obviously improved. However, long-term follow up is lack, and further follow-up effect is lack of powerful support, anddifferent treatment methods and surgical procedures are lack of comparative research. PMID- 29457445 TI - Model for End-Stage Liver Disease and Seven Derivations to Prioritize Liver Transplant Candidates: Which Is the Winner? AB - OBJECTIVES: Under the present liver transplant policy, patients with the highest risk of death receive preference for organ placement. The aim of this study was to evaluate the Model for End-stage Liver Disease (MELD) and seven prognostic derivatives of this test for outcome prediction in cirrhotic patients on liver transplant wait lists. MATERIAL AND METHODS: The study included 416 patients (65.9% male; age 49 +/- 13.9 years) who were entered to liver transplant wait lists from January 2013 to October 2016. Study endpoints were 3-month, 6-month, and 1-year mortality. RESULTS: All prognostic models had acceptable overall performances (0.12 < Brier score < 0.21). The MELD-to-serum sodium ratio test outperformed its counterparts at all 3 endpoints. Estimated C statistics ranged from 0.77 to 0.83. The largest value at 3 months was for the 5-variable MELD score (0.83), and the largest value at 6 months (0.82) and 1 year (0.83) was for the MELD-albumin score. The Hosmer-Lemeshow goodness-of-fit test and calibration plots revealed underestimation for the entire range of predicted risk (P < .001). With decision curve analysis, the MELD-to-serum sodium ratio and United Kingdom Model for End-Stage Liver Disease scoring tests covered the most extensive range of optimal threshold probabilities. CONCLUSIONS: Although some derivations, including sodium and albumin, showed effective prioritization of liver transplant candidates, poor calibration statistics highlighted the need for a recalibration process as an inevitable prerequisite before daily clinical use of these tests at the individual level.

AB - Friction and wear of ultra-high molecular weight polyethylene is a major cause of artificial joint failure. According to mechanism of surface modification method, friction reduction and wear-resistance properties of UHMWPE were improve by several kinds of surface modification methods. Meanwhile, this do not damage the internal structure and properties of UHMWPE. In the process, condition is easy to control and operation is simple. However, reaction time of radiation crosslinking method is too long, the material will be oxidized embrittlement; Monomer itself homopolymerization are seriously in the process of surface grafting; The injection layer of ion implantation methods is very thin and easy to be destroyed. Objective in order to provide a reference for further research on the biotribological properties of ultra-high molecular weight polyethylene artificial joints. At present, as the researches of UHMWPE material main focus on abrasion resistance, and application in the clinical trial is the focus of research, it has a wide prospect in the future. PMID- 29457446 TI - Roll-To-Roll Printing of Meter-Scale Composite Transparent Electrodes with Optimized Mechanical and Optical Properties for Photoelectronics. AB - Flexible transparent electrodes are an indispensable component for flexible optoelectronic devices. In this work, the meter-scale composite transparent electrodes (CTEs) composed of poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) and Ag grid/polyethylene terephthalate (PET) with optimized mechanical and optical properties are demonstrated by slot-die roll-to-roll technique with solution printing method under a low cost ($15-20 per square meter), via control of the viscosity and surface energy of PEDOT:PSS ink as well as the printing parameters. The CTEs show excellent flexibility remaining 98% of the pristine value after bending 2000 times under various bending situations, and the square resistance ( Rs) of CTEs can be reduced to 4.5-5.0 Omega/sq with an appropriate transmittance. Moreover, the optical performances, such as haze, extinction coefficient, and refractive index, are investigated, as compared with indium tin oxide/PET, which are potential for the inexpensive optoelectronic flexible devices. The CTEs could be successfully employed in polymer solar cells with different areas, showing a maximal power conversion efficiency of 8.08%. PMID- 29457447 TI - Effects of Chain Orientation in Self-Organized Buffer Layers Based on Poly(3 alkylthiophene)s for Organic Photovoltaics. AB - Surface-segregated monolayers (SSMs) based on two poly(3-alkylthiophene)s with semifluoroalkyl groups at either the side chains (P3DDFT) or one end of the main chain (P3BT-F17) were used as self-organized buffer layers at the electrode interfaces in bulk heterojunction (BHJ) organic photovoltaic devices. Both of the SSMs greatly shifted the vacuum levels of the BHJ films at the surface due to the aligned permanent dipole moments of the semifluoroalkyl chains. Hole extraction in the BHJ of poly(3-hexylthiophene) (P3HT):[6,6]-phenyl C61-butyric acid methyl ester (PCBM) became more efficient in the presence of the P3DDFT buffer layer, resulting in an improved power conversion efficiency. In contrast, the SSM of P3BT-F17 induced changes in the chain orientation of P3HT and the morphology of the BHJ films, resulting in decreased performance. These results indicate that the molecular design of polymer-based SSMs can affect not only the energy structure at the interface but also the morphology and the molecular orientations in the BHJs. PMID- 29457448 TI - Au/ZnSe-Based Surface Enhanced Infrared Absorption Spectroscopy as a Universal Platform for Bioanalysis. AB - A versatile and sensitive platform for label-free bioanalysis has been proposed on the basis of attenuated total reflection-surface enhanced infrared absorption spectroscopy (ATR-SEIRAS) using Au/ZnSe as the enhancement substrate that allows a wide spectral range down to 700 cm-1. Au nanoparticles are stably deposited on the surface of a ZnSe prism due to the formation of Au-Se bonds via electroless deposition, and the enhancement factor of the resultant Au/ZnSe substrate is about 2 times larger than that of the commonly used Au/Si substrate. As a demonstration, the Au/ZnSe-based SEIRAS has been applied to obtain abundant structural information in the fingerprint region and quantitative analysis of various biomolecular interactions such as DNA hybridization and immunoreaction without any labeling process. PMID- 29457450 TI - Graphdiyne Nanosheet-Based Drug Delivery Platform for Photothermal/Chemotherapy Combination Treatment of Cancer. AB - Nowadays, two-dimensional (2D) materials have attracted extensive attention as cancer drug delivery platforms owing to their unparalleled physicochemical properties and superior specific surface area. Graphdiyne (GDY) is a novel 2D carbon material. Compared with graphene, GDY not only has benzene rings composed of sp2-hybridized carbon atoms but also has acetylene units composed of sp hybridized carbon atoms; therefore, it possesses multiple conjugated electronic structures. Herein, we used doxorubicin (DOX) as a model drug to develop a GDY nanosheet-based drug delivery platform for a photothermal/chemotherapy combination in living mice. With a high photothermal conversion ability and drug loading efficiency, GDY/DOX under 808 nm laser irradiation showed a much higher cancer inhibition rate compared with solo therapy both in vitro and in vivo. Furthermore, GDY exhibited great biocompatibility and no obvious side effects, as shown by histopathological examination and serum biochemical analysis. For the first time, our work demonstrated a successful example of GDY for efficient photothermal/chemotherapy and suggests both safety and great promise for GDY in cancer treatment. PMID- 29457451 TI - Boosted Electrochemical Immunosensing of Genetically Modified Crop Markers Using Nanobody and Mesoporous Carbon. AB - The problems of environmental security and the potential risks of human health caused by transgenic crops have attracted much attention. Recent studies reveal 5 enolpyruvylshikimate-3-phosphate synthase (EPSPS) from Agrobacterium sp. strain CP4 protein (CP4-EPSPS), which shows very high resistance to herbicide glyphosate, is a typical biomarker of genetically modified (GM) crops. For this reason, it is highly anticipated to devise a sensitive and convenient strategy to detect CP4-EPSPS protein in crops. Herein, we report a simple electrochemical immunosensor by coupling nanobody, ordered mesoporous carbon (OMC), and thionine (Th). As a capture agent, the nanobody was screened out from an immunized Bactrian camel, and exhibited superior properties with respect to conventional antibody, such as higher stability and stronger heat resistance. Moreover, OMC offered an effective platform with high surface area, electrical conductivity, and biocompatibility, which greatly facilitated the assembly of redox probe Th, and further coupling of large amount of capture nanobodies. As a result, the CP4 EPSPS protein could be determined with high sensitivity and efficiency by differential pulse voltammetry (DPV) in a wide linear range from 0.001 to 100 ng.mL-1 with a low detection limit of 0.72 pg.mL-1, which was more than 3 orders of magnitude lower than those of previously reported works. As an example, the proposed electrochemical immunosensor was successfully applied to spiked samples, demonstrating its great potential in CP4-EPSPS screening and detection. PMID- 29457449 TI - Catalytically Active Single-Chain Polymeric Nanoparticles: Exploring Their Functions in Complex Biological Media. AB - Dynamic single-chain polymeric nanoparticles (SCPNs) are intriguing, bioinspired architectures that result from the collapse or folding of an individual polymer chain into a nanometer-sized particle. Here we present a detailed biophysical study on the behavior of dynamic SCPNs in living cells and an evaluation of their catalytic functionality in such a complex medium. We first developed a number of delivery strategies that allowed the selective localization of SCPNs in different cellular compartments. Live/dead tests showed that the SCPNs were not toxic to cells while spectral imaging revealed that SCPNs provide a structural shielding and reduced the influence from the outer biological media. The ability of SCPNs to act as catalysts in biological media was first assessed by investigating their potential for reactive oxygen species generation. With porphyrins covalently attached to the SCPNs, singlet oxygen was generated upon irradiation with light, inducing spatially controlled cell death. In addition, Cu(I)- and Pd(II)-based SCPNs were prepared and these catalysts were screened in vitro and studied in cellular environments for the carbamate cleavage reaction of rhodamine-based substrates. This is a model reaction for the uncaging of bioactive compounds such as cytotoxic drugs for catalysis-based cancer therapy. We observed that the rate of the deprotection depends on both the organometallic catalysts and the nature of the protective group. The rate reduces from in vitro to the biological environment, indicating a strong influence of biomolecules on catalyst performance. The Cu(I)-based SCPNs in combination with the dimethylpropargyloxycarbonyl protective group showed the best performances both in vitro and in biological environment, making this group promising in biomedical applications. PMID- 29457452 TI - Multiple Stimuli-Responsive Fluorescent Sensor from Citric Acid and 1-(2 Aminoethyl)piperazine. AB - Multiresponsive fluorescent supramolecular materials are quite interesting, for they combine the multiresponsiveness of supramolecules and the high sensitivity of fluorescent materials. Different from the multiresponsive supramolecular materials based on host-guest interactions, in this report, a supramolecular ionic network was fabricated by 1-(2-aminoethyl)piperazine and citric acids via ionic interactions. Despite the fact that there are no conventional chromophores, the obtained supramolecular ionic material can emit strong fluorescence. Most interestingly, the thin film of this supramolecular ionic material can change its fluorescent intensity in response to four external stimuli, including humidity, triethylamine, acetic acid, and temperature. Beneficial to the supramolecular ionic structure, this multiresponsive fluorescent sensor is self-healable. It is found that a new route has been opened to prepare the multiresponsive fluorescent sensors. PMID- 29457453 TI - Exquisite Enzyme-Fenton Biomimetic Catalysts for Hydroxyl Radical Production by Mimicking an Enzyme Cascade. AB - Hydrogen peroxide (H2O2) is a key reactant in the Fenton process. As a byproduct of enzymatic reaction, H2O2 can be obtained via catalytical oxidation of glucose using glucose oxidase in the presence of O2. Another oxidation product (gluconic acid) can suitably adjust the microenvironmental pH contributing to the Fe3+/Fe2+ cycle in the Fenton reaction. Enzymes are extremely efficient at catalyzing a variety of reactions with high catalytic activity, substrate specificity, and yields in living organisms. Inspired by the multiple functions of natural multienzyme systems, an exquisite nanozyme-modified alpha-FeOOH/porous carbon (PC) biomimetic catalyst constructed by in situ growth of glucose oxidase mimicking Au nanoparticles and crystallization of adsorbed ferric ions within carboxyl into hierarchically PC is developed as an efficient enzyme-Fenton catalyst. The products (H2O2, ~4.07 mmol.L-1) of the first enzymatic reaction are immediately used as substrates for the second Fenton-like reaction to generate the valuable *OH (~96.84 MUmol.L-1), thus mimicking an enzyme cascade pathway. alpha-FeOOH nanocrystals, attached by C-O-Fe bondings, are encapsulated into the mesoporous PC frameworks, facilitating the electron transfer between alpha-FeOOH and the PC support and greatly suppressing iron leaching. This study paves a new avenue for designing biomimetic enzyme-based Fenton catalysts mimicking a natural system for *OH production. PMID- 29457454 TI - Rationally Designed, Multifunctional Self-Assembled Nanoparticles for Covalently Networked, Flexible and Self-Healable Superhydrophobic Composite Films. AB - For constructing bioinspired functional films with various superhydrophobic functions, including self-cleaning, anticorrosion, antibioadhesion, and oil-water separation, hydrophobic nanomaterials have been widely used as crucial structural components. In general, hydrophobic nanomaterials, however, cannot form strong chemical bond networks in organic-inorganic hybrid composite films because of the absence of chemically compatible binding components. Herein, we report the rationally designed, multifunctional self-assembled nanoparticles with tunable functionalities of covalent cross-linking and hydrophobicity for constructing three-dimensionally interconnected superhydrophobic composite films via a facile solution-based fabrication at room temperature. The multifunctional self assembled nanoparticles allow the systematic control of functionalities of composite films, as well as the stable formation of covalently linked superhydrophobic composite films with excellent flexibility (bending radii of 6.5 and 3.0 mm, 1000 cycles) and self-healing ability (water contact angle > 150 degrees , >=10 cycles). The presented strategy can be a versatile and effective route to generating other advanced functional films with covalently interconnected composite networks. PMID- 29457455 TI - Ultrathin kappa-Carrageenan/Chitosan Hydrogel Films with High Toughness and Antiadhesion Property. AB - Designing tough biopolymer-based hydrogels as structural biomaterials has both scientific and practical significances. We report a facile approach to prepare polysaccharide-based hydrogel films with remarkable mechanical performances and antiadhesion property. The hydrogel films with a thickness of 40-60 MUm were prepared by mixing aqueous solutions of kappa-carrageenan (kappa-CG) and protonated chitosan (CS), evaporating the solvent, and then swelling the casted film in water to achieve the equilibrium state. The obtained kappa-CG/CS gel films with a water content of 48-88 wt % possessed excellent mechanical properties with a breaking stress of 2-6.7 MPa and a breaking strain of 80-120%, superior to the most existing biopolymer-based hydrogels. The extraordinary mechanical properties of gel films obtained over a wide range of mass ratio of kappa-CG to CS should be rooted in the synergistic effect of ionic and hydrogen bonds between the kappa-CG and CS molecules. In addition, the tough gel films showed good self-recovery ability, biocompatibility, and cell antiadhesion property, making them promising as an artificial dura mater and diaphragm materials in the surgery. The design principle by incorporating multiple noncovalent bonds to toughen the biopolymer-based hydrogels should be applicable to other systems toward structural biomaterials with versatile properties.

AB - Enyne ring closing metathesis has been used to synthesize functional group carrying metathesis catalysts from a commercial (Ru-benzylidene) Grubbs' catalysts. The new Grubbs-type ruthenium carbene was used to synthesize living heterotelechelic ROMP polymers without any intermediate purification. Olefin metathesis with a mono substituted alkyne followed by ring closing metathesis with an allylic ether provided efficient access to new functional group carrying metathesis catalysts. Different functional benzylidene and alkylidene derivatives have been investigated in the synthesis of heterotelechelic polymers in one pot. PMID- 29457457 TI - Programming Hierarchical Self-Assembly of Patchy Particles into Colloidal Crystals via Colloidal Molecules. AB - Colloidal self-assembly is a promising bottom-up route to a wide variety of three dimensional structures, from clusters to crystals. Programming hierarchical self assembly of colloidal building blocks, which can give rise to structures ordered at multiple levels to rival biological complexity, poses a multiscale design problem. Here we explore a generic design principle that exploits a hierarchy of interaction strengths and employ this design principle in computer simulations to demonstrate the hierarchical self-assembly of triblock patchy colloidal particles into two distinct colloidal crystals. We obtain cubic diamond and body-centered cubic crystals via distinct clusters of uniform size and shape, namely, tetrahedra and octahedra, respectively. Such a conceptual design framework has the potential to reliably encode hierarchical self-assembly of colloidal particles into a high level of sophistication. Moreover, the design framework underpins a bottom-up route to cubic diamond colloidal crystals, which have remained elusive despite being much sought after for their attractive photonic applications. PMID- 29457458 TI - Amphiphilic Functionalized Acupuncture Needle as SERS Sensor for In Situ Multiphase Detection. AB - Surface enhanced Raman spectroscopy (SERS) is a powerful spectroscopic technique with unique vibrational fingerprints, making it an ideal candidate for in situ multiphase detection. However, it is a great challenge to determine how to guide the SERS sensor to target molecules of interest in multiphase heterogeneous samples with minimal disturbance. Here, we present a portable ultrasensitive and highly repeatable SERS sensor for in situ multiphase detection. The sensor is composed of commercial Ag acupuncture needle and PVP-Au nanoparticles (Au NPs). The PVP on the Au NPs can adsorb and induce the Au NPs into a highly uniform array on the surface of the Ag needle because of its adhesiveness and steric nature. The Au NPs-Ag Needle system (Au-AgN) holds a huge SERS effect, which is enabled by the multiple plasmonic couplings from particle-film and interparticle. The PVP, as the amphiphilic polymer, promotes the target molecules to adsorb on surface of the Au-AgN whether in the oil phase or in the water phase. In this work, the Au-AgN sensor was directly inserted into the multiphase system with the laser in situ detection, and SERS detection at different spots of the Au-AgN sensor provided Raman signal of targets molecule in the different phase. In situ multiphase detection can minimize the disturbance of sampling and provide more accurate information. The facile fabrication and amphiphilic functionalization make Au-AgN sensor as generalized SERS detection platform for on-site testing of aqueous samples, organic samples, even the multiphase heterogeneous samples.

AB - The tetrapyridinium salt 1 was found to undergo quantitative air oxidation upon dissolving it in water. The corresponding alkene and the epoxide were found as the only products of the oxidation. A mechanism that involves an alkyl hydroperoxide intermediate 1" undergoing a transformation that yields both products is proposed. Air oxidation of 1 shows the potential of the acceptor substituted alkanes to be used in the studies of mostly unknown direct epoxidation of single C-C bonds. PMID- 29457460 TI - Stressful Surfaces: Cell Metabolism on a Poorly Adhesive Substrate. AB - The adhesion and proliferation of cells are exquisitely sensitive to the nature of the surface to which they attach. Aside from cell counting, cell "health" on surfaces is typically established by measuring the metabolic rate with dyes that participate in the metabolic pathway or using "live/dead" assays with combinations of membrane permeable/impermeable dyes. The binary information gleaned from these tests-whether cells are attached or not, and whether they are living or dead-provides an incomplete picture of cell health. In the present work, proliferation rates and net metabolism of 3T3 fibroblasts seeded on "biocompatible" ultrathin polyelectrolyte multilayer films and on control tissue culture plastic were compared. Cells adhered to, and proliferated on, both surfaces, which were shown to be nontoxic according to live/dead assays. However, adhesion was poorer on the multilayer surface, illustrated by diffuse organization of the actin cytoskeleton and less-developed focal adhesions. Proliferation was also slower on the multilayer. When normalized for the total number of cells, it was shown that cells on multilayers experienced a five-day burst of metabolic stress, after which the metabolic rate approached that of the control surface. This initial state of high stress has not been reported or appreciated in studies of cell growth on multilayers, although the observation period for this system is usually a few days.

PMID- 29457462 TI - Determination of Site-Specific Phosphorylation Ratios in Proteins with Targeted Mass Spectrometry. AB - We show that parallel reaction monitoring (PRM) can be used for exact quantification of phosphorylation ratios of proteins using stable-isotope-labeled peptides. We have compared two different PRM approaches on a digest of a U87 cell culture, namely, direct-PRM (tryptic digest measured by PRM without any further sample preparation) and TiO2-PRM (tryptic digest enriched with TiO2 cartridges, followed by PRM measurement); these approaches are compared for the following phosphorylation sites: neuroblast differentiation-associated protein (AHNAK S5480 p), calcium/calmodulin-dependent protein kinase type II subunit delta (CAMK2D T337-p), and epidermal growth factor receptor (EGFR S1166-p). A reproducible percentage of phosphorylation could be determined (CV 6-13%) using direct-PRM or TiO2-PRM. In addition, we tested the approaches in a cell culture experiment in which U87 cells were deprived of serum. As a "gold standard" we included immune precipitation of EGFR followed by PRM (IP-PRM). For EGFR (S1166) and AHNAK (S5480) a statistical significant change in the percentage of phosphorylation could be observed as a result of serum deprivation; for EGFR (S1166) this change was observed for both TiO2-PRM and IP-PRM. The presented approach has the potential to multiplex and to quantify the ratio of phosphorylation in a single analysis. PMID- 29457463 TI - ICRP Publication 138: Ethical Foundations of the System of Radiological Protection. AB - Abstract -: Despite a longstanding recognition that radiological protection is not onlya matter of science, but also ethics, ICRP publications have rarely addressed theethical foundations of the system of radiological protection explicitly. The purposeof this publication is to describe how the Commission has relied on ethical values,either intentionally or indirectly, in developing the system of radiological protectionwith the objective of presenting a coherent view of how ethics is part of this system.In so doing, it helps to clarify the inherent value judgements made in achieving theaim of the radiological protection system as underlined by the Commission inPublication 103. Although primarily addressed to the radiological protection community,this publication is also intended to address authorities, operators, workers,medical professionals, patients, the public, and its representatives (e.g. NGOs) actingin the interest of the protection of people and the environment. This publicationprovides the key steps concerning the scientific, ethical, and practical evolutions ofthe system of radiological protection since the first ICRP publication in 1928. It thendescribes the four core ethical values underpinning the present system: beneficence/non-maleficence, prudence, justice, and dignity. It also discusses how these coreethical values relate to the principles of radiological protection, namely justification,optimisation, and limitation. The publication finally addresses key procedural valuesthat are required for the practical implementation of the system, focusing onaccountability, transparency, and inclusiveness. The Commission sees this publicationas a founding document to be elaborated further in different situations andcircumstances. PMID- 29457464 TI - Assessment of DNA Methylation Patterns in the Bone and Cartilage of a Nonhuman Primate Model of Osteoarthritis. AB - Objective Osteoarthritis (OA) affects humans and several other animals. Thus, the mechanisms underlying this disorder, such as specific skeletal tissue DNA methylation patterns, may be evolutionary conserved. However, associations between methylation and OA have not been readily studied in nonhuman animals. Baboons serve as important models of disease and develop OA at rates similar to those in humans. Therefore, this study investigated the associations between methylation and OA in baboons to advance the evolutionary understanding of OA. Design Trabecular bone and cartilage was collected from the medial condyles of adult female baboon femora, 5 with and 5 without knee OA. The Infinium HumanMethylation450 BeadChip (450K array) was used to identify DNA methylation patterns in these tissues. Results Approximately 44% of the 450K array probes reliably align to the baboon genome, contain a CpG site of interest, and maintain a wide distribution throughout the genome. Of the 2 filtering methods tested, both identified significantly differentially methylated positions (DMPs) between healthy and OA individuals in cartilage tissues, and some of these patterns overlap with those previously identified in humans. Conversely, no DMPs were found between tissue types or between disease states in bone tissues. Conclusions Overall, the 450K array can be used to measure genome-wide DNA methylation in baboon tissues and identify significant associations with complex traits. The results of this study indicate that some DNA methylation patterns associated with OA are evolutionarily conserved, while others are not. This warrants further investigation in a larger and more phylogenetically diverse sample set. PMID- 29457465 TI - Further Evaluation of a Practitioner Model for Increasing Eye Contact in Children With Autism. AB - Cook et al. recently described a progressive model for teaching children with autism spectrum disorder (ASD) to provide eye contact with an instructor following a name call. The model included the following phases: contingent praise only, contingent edibles plus praise, stimulus prompts plus contingent edibles and praise, contingent video and praise, schedule thinning, generalization assessments, and maintenance evaluations. In the present study, we evaluated the extent to which modifications to the model were needed to train 15 children with ASD to engage in eye contact. Results show that 11 of 15 participants acquired eye contact with the progressive model; however, eight participants required one or more procedural modifications to the model to acquire eye contact. In addition, the four participants who did not acquire eye contact received one or more modifications. Results also show that participants who acquired eye contact with or without modifications continued to display high levels of the behavior during follow-up probes. We discuss directions for future research with and limitations of this progressive model. PMID- 29457466 TI - Feasibility of an Alzheimer's disease knowledge intervention in the Latino community. AB - BACKGROUND: Latinos experience disparities in Alzheimer's disease (AD) knowledge. The aim of this study was to explore the feasibility of a 45-minute culturally tailored AD knowledge presentation for professionals serving the Latino community and Latinos served by Latino community organizations. METHODS: One-session AD knowledge lunch-and-learn events were conducted with 40 professionals and 37 served Latinos. Participants received a pre-post survey including questions on satisfaction, a subjective AD knowledge question and a 14 item objective AD knowledge questionnaire. RESULTS: Professionals (54.3%) and served Latinos (94.6%) reported the session as being very enjoyable and increased in objective AD knowledge (2.1 and 2.5 units, p < .001) and subjective knowledge (1.1 and 1.7 units; p < .001). DISCUSSION: A brief in-person culturally-tailored session of AD education increases short-term AD knowledge and is perceived as interesting and useful among professionals serving the Latino community and Latinos served by Latino community organizations.

PMID- 29457468 TI - Experiences of racism, sexual objectification and alcohol use among gay and bisexual men of colour. AB - OBJECTIVE: Previous research has shown that experiences of racial discrimination and sexual objectification are associated with health risk behaviours among gay and bisexual men of colour. However, little is known about whether racial discrimination and sexual objectification are associated with alcohol use among this population. This community-based study examined the association between racial discrimination, sexual objectification and alcohol use in a sample of 369 gay and bisexual men of colour (Black/African/Caribbean, Latino/Latin American, South Asian, and East and Southeast Asian) in Toronto. DESIGN: Data were drawn from an online survey designed to examine issues of racism, homophobia, health and well-being among gay and bisexual men of colour in Toronto. Regression analysis assessed the relationship between scores on the Racism and Life Experiences Scale, Sexual Objectification Scale, and the CAGE questionnaire (a screen for alcohol use disorder). RESULTS: Multivariable logistic regression analyses revealed that experiences of racism and sexual objectification are significantly and positively associated with a screening for alcohol use disorder. The interactions between Latino/Latin American race/ethnicity and experience of sexual objectification were also positively associated with a screening for alcohol use disorder. CONCLUSIONS: Health professionals should consider the role of racial discrimination and sexual objectification within the context of risk and treatment for alcohol use disorders, harm reduction, and HIV prevention for gay and bisexual men of colour. PMID- 29457469 TI - Development of an operational manual for a consultation-liaison psychiatry service. AB - OBJECTIVES: Consultation-liaison psychiatry (CLP) services sit between mental health and the general hospital, and risk being poorly understood by both systems. The aim of this study was to develop an operational manual for a CLP service, which defined functions and governance. METHODS: The CLP literature was reviewed with a focus on descriptions of CLP roles, organisational processes, quality measures and service development. The CLP team held service planning meetings and met with members of the mental health and hospital executives. Site visits and collaboration with other CLP services occurred in defining the roles of the CLP service and organisational governance. RESULTS: A CLP operational document was developed, including a description of the service, its functions, staff roles and governance. Procedural information such as the CLP timetable, referral process, triage and assessment, documentation, activity recording, quality assurance and relevant policies were outlined. CONCLUSIONS: The development of a dedicated operational manual for CLP clarified the roles, functions and governance of CLP within the general hospital and mental health systems. The development process facilitated the engagement of key clinicians and administrators of these systems, the determination of quality improvement targets and greater transparency and accountability. PMID- 29457470 TI - Shared decision-making in psychiatry: a study of patient attitudes. AB - OBJECTIVES: Shared decision-making (SDM) is promoted as beneficial in mental healthcare, despite a dearth of supportive evidence. We aimed to obtain patients' perspective on SDM in a 'real world' hospital sample. METHODS: Structured validated questionnaires were used to examine SDM with regard to treatment choices, and whether SDM influences attitudes towards treatment. The Mini-Mental State Examination was used to assess decision-making capacity. RESULTS: A total of 109 individuals participated, with 60% reporting experiencing SDM. SDM positively correlated with positive attitudes to medication. Those detained under the Mental Health Act had lower levels of SDM. CONCLUSIONS: SDM leads to more positive attitudes towards medication and may improve adherence with treatment. SDM may particularly benefit those subject to involuntary treatment and is not onerous to practice. PMID- 29457471 TI - Beck Depression Inventory as a screening tool for depression in chronic haemodialysis patients. AB - OBJECTIVES: To evaluate the psychometric properties of the Beck Depression Inventory (BDI) and Cognitive Depression Index (CDI) as a potential screening tool for major depression in haemodialysis (HD) patients. METHODS: Forty-five HD patients completed both the BDI/CDI and diagnostic interview. The interview was conducted by two experienced clinicians and was based on DSM-IV criteria. The sensitivity, specificity and positive (PPV) and negative (NPV) predictive values were then calculated. RESULTS: A diagnosis of depression was found in 6 of the 45 participants (13.3%). Optimal cut-offs were >=18 for the BDI (sensitivity 1.0, specificity 0.90, PPV 0.60, NPV 1.0) and >=11 for the CDI (sensitivity 1.0, specificity 0.92, PPV 0.67, NPV 1.0). CONCLUSIONS: Both the BDI and CDI were shown to be acceptable screening tools for depression in this population of chronic HD patients. The recommended cut-off scores for both scales are higher than those suggested for the general population and slightly higher than previously found in the chronic kidney disease literature, suggesting that altered thresholds are required when using these screening tools amongst HD patients. PMID- 29457473 TI - Going the distance: reviewing antipsychotic depot or long-acting injectable treatments in Australasia. AB - OBJECTIVES: The aim of this study is to provide an opinion paper reviewing the role of depot or long-acting injectable (LAI) antipsychotic medications, with comments on individual newer LAIs such aripiprazole maintena and paliperidone palmitate. In particular, we share our recent experience of using paliperidone three-monthly LAI. We also reflect on the associated benefits and potential harms of LAIs, and when they may be used. CONCLUSIONS: LAI antipsychotics are an important and arguably under-utilised therapeutic option, particularly where medication adherence is a priority, and where an informed patient opts for this formulation. Paliperidone is the first three-monthly LAI antipsychotic, and as such represents a significant advance in the range of treatment choices. PMID- 29457474 TI - The Importance of Calibration in Clinical Psychology. AB - Accuracy has several elements, not all of which have received equal attention in the field of clinical psychology. Calibration, the degree to which a probabilistic estimate of an event reflects the true underlying probability of the event, has largely been neglected in the field of clinical psychology in favor of other components of accuracy such as discrimination (e.g., sensitivity, specificity, area under the receiver operating characteristic curve). Although it is frequently overlooked, calibration is a critical component of accuracy with particular relevance for prognostic models and risk-assessment tools. With advances in personalized medicine and the increasing use of probabilistic (0% to 100%) estimates and predictions in mental health research, the need for careful attention to calibration has become increasingly important. PMID- 29457475 TI - Civil forensic psychiatry - Part 2: specific issues. AB - OBJECTIVES: This paper describes the main areas of civil forensic psychiatry (FP) and the skills required by psychiatric experts. Some specific areas of civil FP are discussed, including tort law reform, reliability of psychiatric evidence, contentious psychiatric disorders, and the many domains of civil FP. CONCLUSIONS: Civil FP is an important sub-specialty component of forensic psychiatry that requires greater emphasis in the training and continuing education of psychiatrists. A process of accrediting psychiatrists as having competency in advanced civil FP may be of value. PMID- 29457478 TI - The interrelationships among pain interference, depressive symptoms, loneliness, and employment status: a moderated mediation study. AB - OBJECTIVE: To explore the mediating effect of loneliness on the relationship between pain interference and depressive symptoms and to determine whether this mechanism is contingent on employment status. DESIGN: Cross-sectional study. SUBJECTS: A total of 876 adult caregivers of adolescents living in extremely impoverished conditions. ANALYSIS: Mediation and moderated mediation analyses using standard path-analytic approaches. RESULTS: The mean age of the sample was 39.0 (SD = 12.8) years and 80.7% ( n = 707) identified as female. Almost half (48.9%, n = 425) of the participants did not report any pain, while 32.5% ( n = 285) reported non-disabling pain, and 19.0% ( n = 166) reported disabling pain. The mean depressive symptoms score was 16.20 (SD = 10.6), and the mean loneliness score was 40.09 (SD = 10.5). Loneliness mediated the effect of both non-disabling and disabling pain on depressive symptoms. However, the indirect effect of pain interference on depressive symptoms through loneliness was more pronounced among participants reporting disabling pain (coefficient, 2.11; Boot 95% confidence interval (CI) (1.25-3.01)) than non-disabling pain (coefficient, 0.99; Boot 95% CI (0.25-1.76)). Moderated mediation results showed that the indirect effect of pain interference on depressive symptoms, via loneliness varied in magnitude as a function of employment status among participants reporting disabling pain but not those reporting non-disabling pain. CONCLUSION: Loneliness provides an important link in the relationship between depressive symptoms and pain interference. Furthermore, employment status is an important factor to consider, especially among individuals reporting disabling pain with comorbid depressive symptoms.

AB - OBJECTIVES:: The aim of this study was to identify the most effective interventions for early intervention in psychosocial disability in the National Disability Insurance Scheme (NDIS) through an evidence review. METHODS:: A series of rapid reviews were undertaken to establish possible interventions for psychosocial disability, to develop our understanding of early intervention criteria for the NDIS and to determine which interventions would meet these criteria. RESULTS:: Three interventions (social skills training, supported employment and supported housing) have a strong evidence base for effectiveness in early intervention in people with psychosocial disability, with the potential for adoption by the NDIS. They support personal choice and recovery outcomes. Illness self-management, cognitive remediation and cognitive behavioural therapy for psychosis demonstrate outcomes to mitigate impairment. The evidence for family psycho-education is also very strong. CONCLUSIONS:: This review identified evidence-based, recovery-oriented approaches to early intervention in psychosocial disability. They meet the criteria for early intervention in the NDIS, are relevant to participants and consider their preferences. Early intervention has the potential to save costs by reducing participant reliance on the scheme. PMID- 29457481 TI - Selection and Use of Health Services for Infants' Needs by Indigenous Mothers in Canada: Integrative Literature Review. AB - In Canada, Indigenous infants experience significant health disparities when compared to non-Indigenous infants, including significantly higher rates of birth complications and infant mortality rates. The use of primary health care is one way to improve health outcomes; however, Indigenous children may use health services less often than non-Indigenous children. To improve health outcomes within this growing population, it is essential to understand how caregivers, defined here as mothers, select and use health services in Canada. This integrative review is the first to critique and synthesize what is known of how Indigenous mothers in Canada experience selecting and using health services to meet the health needs of their infants. Themes identified suggest both Indigenous women and infants face significant challenges; colonialism has had, and continues to have, a detrimental impact on Indigenous mothering; and very little is known about how Indigenous mothers select and use health services to meet the health of their infants. This review revealed significant gaps in the literature and a need for future research. Suggestions are made for how health providers can better support Indigenous mothers and infants in their use of health services, based on what has been explored in the literature to date. PMID- 29457482 TI - Dark and Bright-Two Sides of Family-Centered Care in the NICU: A Qualitative Study. AB - Nurses in the Neonatal Intensive Care Unit (NICU) have an important role in implementing family-centered care (FCC). The aim of the study was to explore the lived experiences of NICU nurses on implementing FCC. An interpretative phenomenological study was conducted and 11 employed nurses were interviewed from April 2015 to February 2016. The data were analyzed through the Diekelmann, Allen, and Tanner approach. Four main themes of "strain to achieve stability," "bewildered by taking multiple roles," "accepting the family," and "reaching bright horizon" were extracted. This study provided deeper understanding about nurses' perceptions of FCC implementation. In Muslim developing countries, FCC implementation is challenging and nurses are under extra pressure because of a shortage in nursing workforce; however, having positive experiences with family participation and valuing theism beliefs allowed them to support family involvement. Support of nurses to take FCC strategies in the NICU is needed by officials overseeing the health care system. PMID- 29457483 TI - Sensitivity of the Saline Load Test for Traumatic Arthrotomy of the Ankle With Ankle Arthroscopy Simulation. AB - BACKGROUND: The saline load test has been used to evaluate for traumatic arthrotomy in orthopedics. The purpose of this study was to determine the volume of saline required to detect traumatic arthrotomy of the ankle. METHODS: Forty two patients undergoing elective ankle arthroscopy were prospectively enrolled. For each patient, a standard 4-mm anteromedial portal was established. Next, an 18-gauge needle was inserted at the site of the anterolateral portal. Sterile saline was slowly injected through the needle until saline extravasated from the anteromedial portal. Saline volumes at the time of extravasation were recorded and analyzed. RESULTS: The saline volume required to achieve extravasation ranged from 0.2 to 60.0 mL. The median saline volume required to achieve extravasation was 9.7 mL (interquartile range, 3.8-29.6 mL); however, 5 of 42 patients required volumes between 50.0 and 60.0 mL. A total of 50.0 mL was required to achieve 90% sensitivity, 55.0 mL to achieve 95% sensitivity, and 60.0 mL to achieve 99% sensitivity. CONCLUSIONS: The previously recommended 30 mL of saline required to reliably detect traumatic arthrotomy of the ankle may be too small a volume. CLINICAL RELEVANCE: The present study suggests that clinicians should attempt to inject 60 mL of saline to effectively rule out a traumatic arthrotomy injury. Because of the study's methods involving an anteromedial arthrotomy with anterolateral saline injection, these findings may be most valid for arthrotomies on the medial side of the ankle. PMID- 29457484 TI - Cryosurgery + 5% 5-Fluorouracil for Treatment of Superficial Basal Cell Carcinoma and Bowen's Disease [Formula: see text]. AB - BACKGROUND: Superficial basal cell carcinoma (sBCC) and squamous cell carcinoma in situ (SCCis) are 2 types of nonmelanoma skin cancers (NMSCs) that are amenable to treatment with topical 5-fluorouracil, cryosurgery, or topical imiquimod, among other destructive and surgical modalities. There are few studies examining the effectiveness of combination therapy with 5% 5-fluorouracil and cryosurgery for the treatment of sBCC and SCCis. OBJECTIVES: Our objective was to study the clinical cure rate achieved with the regimen of cryosurgery and a 3-week course of 5% 5-fluorouracil in the treatment of biopsy-proven sBCC and SCCis. METHODS: A retrospective chart review of patients treated with cryosurgery and a 3-week course of 5% 5-fluorouracil was performed. Immunocompetent patients with biopsy proven sBCC or SCCis who completed the treatment and attended a follow-up appointment at 6 months were included in the study. RESULTS: On clinical examination, 30 sBCC lesions of the 34 that were assessed and 31 SCCis lesions of the 33 that were assessed demonstrated no evidence of recurrence. The clinical cure rates were found to be 73% (sBCC) and 82% (SCCis), with the inclusion of patients that were lost to follow-up. CONCLUSIONS: This approach may represent a suitable option for select patients for the treatment of SCCis. Further studies with a longer follow-up duration, documentation of histologic cure, and tolerability of this regimen for SCCis are needed. The effectiveness of cryosurgery and 5-fluorouracil for sBCC requires further study. PMID- 29457485 TI - Atopy Associated With Positive Patch Test and Possible Allergic Contact Dermatitis. AB - BACKGROUND: Atopy is a genetic predisposition to the development of allergic reactions and the increased production of immunoglobulin E (IgE) upon exposure to environmental antigens. Clinical manifestations of atopy include asthma, atopic dermatitis (AD), and allergic rhinoconjunctivitis (ARC). OBJECTIVE: To determine if cutaneous delayed hypersensitivity reactions (CDHRs) as assessed by patch testing are higher among patients with a history of atopy and with a familial predisposition to atopy. METHODS: For this study, we reviewed the patch test database of the UBC Contact Dermatitis Clinic over a 4-year time span. A personal history of asthma, AD, and ARC was recorded. In addition, a family history was obtained and manifestations of atopy in family members were noted. RESULTS: A total of 1515 patients were included in this study. Our data show that the odds ratio (OR) of a positive patch test with a personal history of atopy was 1.39, while the OR of a positive patch test with a family history of atopy was 1.69. Conversely, a personal history of respiratory atopy did not significantly affect the probability of a positive patch test, with an OR of 1.03. CONCLUSION: We conclude from our study that patients with a personal or family history of atopy have an increased risk of allergic contact dermatitis (ACD). These results provide further evidence for the link between atopy and ACD and suggest that children of atopic parents should avoid potential contact allergens and would likely benefit from prophylactic emollient use. PMID- 29457486 TI - Case Report of Empagliflozin-Induced Cutaneous Polyarteritis Nodosa. AB - Polyarteritis nodosa (PAN) is a rare vasculitis affecting medium-sized vessels. Cutaneous PAN is a clinical variant, and we report the first case of empagliflozin-induced cutaneous PAN in a 69-year-old man. After starting empagliflozin, the patient presented with tender subcutaneous nodules on his legs, which showed a medium-sized vessel vasculitis on histopathology. Upon cessation of this medication, he had full resolution of these nodules. This case illustrates that empagliflozin can induce cutaneous PAN, and further attention to this medication's association with cutaneous PAN is warranted. PMID- 29457487 TI - Dementia management strategies associated with neuropsychiatric symptoms of elderly people with Alzheimer's disease. AB - This study aims to investigate the association between management and communication strategies and the presence of neuropsychiatric symptoms presented by elderly people with Alzheimer's disease. One hundred and thirty-four family caregivers answered a questionnaire with socio-demographic data and questions regarding the care context, the Small Communication Strategies Scale, the Dementia Management Strategy Scale, and the Neuropsychiatric Inventory. Caregivers used the criticism management strategy more when the elderly presented hallucination, agitation, depression, anxiety, irritability, nighttime behavior, and appetite abnormalities. The encouragement strategy was more significantly used only in the presence of euphoria/elation. The caregivers who used the most active management strategy were those who cared for the elderly with delirium, hallucination, agitation, depression, anxiety, irritability, and appetite and eating abnormalities. The use of communication strategies did not differ between groups with or without neuropsychiatric symptoms. It is concluded that criticism management and active management strategies are strongly associated with neuropsychiatric symptoms. The results of this study may be useful for planning treatment interventions that aim to modify the use of management strategies used by caregivers. PMID- 29457488 TI - Referral patterns and implementation costs of the Partners in Recovery initiative in Gippsland: learnings for the National Disability Insurance Scheme. AB - OBJECTIVE:: The purpose of this paper is to provide some learnings for the NDIS from the referral pattern and cost of implementing the Partners in Recovery initiative of Gippsland. METHOD:: Information on referral areas made for each consumer was collated from support facilitators. Cost estimates were determined using budget estimates, administrative costs and a literature review and are reported from a government perspective. RESULTS:: Sixty-three per cent of all referrals were made to organisations that provided multiple types of services. Thirty-one per cent were to Mental Health Community Support Services. Eighteen per cent of referrals were made to clinical mental health services. The total cost of providing the service for a consumer per year (set-up and ongoing) was estimated to be AUD$15,755 and the ongoing cost per year was estimated to be AUD$13,434. The cost of doing nothing is likely to cost more in the longer term, with poor mental health outcomes such as hospital admission, unemployment benefits, prison, homelessness and psychiatric residential care. CONCLUSIONS:: Supporting recovery in persons with Severe and Persistent Mental Illness is likely to be economically more beneficial than not doing so. Recovery can be better supported when frequently utilised services are co-located. These might be some learnings for the NDIS. PMID- 29457489 TI - Shingrix: The New Adjuvanted Recombinant Herpes Zoster Vaccine. AB - OBJECTIVES: To review the immunogenicity, efficacy, and safety of the herpes zoster subunit vaccine (HZ/su) for use in adult patients for the prevention of shingles. DATA SOURCES: A literature search through PubMed was conducted (June 2008 to October 2017) using the terms shingles vaccine and varicella zoster virus. References from retrieved articles and the prescribing information were also reviewed for any additional material. STUDY SELECTION/DATA EXTRACTION: The literature search was limited to human studies published in English. Randomized controlled, multicenter trials were reviewed and included to evaluate the safety and efficacy of HZ/su. Literature on the epidemiology and pathology of herpes zoster virus infections and recommendations from the Advisory Committee on Immunization Practices (ACIP) were also reviewed. DATA SYNTHESIS: HZ/su is a new adjuvanted recombinant vaccine approved by the Food and Drug Administration for the prevention of herpes zoster in adults 50 years of age and older. HZ/su significantly reduced the risk of developing herpes zoster by more than 90% as compared with placebo and displayed a comparable adverse effect profile. The most common local adverse events were injection site pain, redness, and swelling, and the most common systemic adverse events were myalgia, fatigue, and headache. The ACIP recommends the routine use of HZ/su as the preferred vaccine for the prevention of herpes zoster in immunocompetent adults 50 years of age and older. CONCLUSIONS: Based on published immunogenicity, efficacy, and safety data, as well as the recent recommendations by the ACIP, HZ/su should be included on both hospital and community pharmacy formularies and recommended to all immunocompetent patients older than 50 years to prevent herpes zoster. PMID- 29457490 TI - Demonstration of Resistant or Wild-Type Virus in Recurrent Viremia After Ganciclovir-Resistant Cytomegaloviral Infection. AB - BACKGROUND: Ganciclovir-resistant cytomegalovirus (GR-CMV) is a serious complication of transplantation. Recurrence after primary infection is common. Little is known about CMV drug resistance and latency. OBJECTIVE: Review CMV genotype during episodes of recurrent CMV viremia after prior documentation of ganciclovir resistance to evaluate if resistance is redemonstrated. METHODS: All adult transplant recipients with history of GR-CMV viremia from January 1, 2011, to December 31, 2015, were screened; those with subsequent laboratory evidence of recurrent CMV viremia and genotyping were included. RESULTS: A total of 23 patients had genetically confirmed GR-CMV within the study time period; 14 were excluded due to lack of repeat resistance testing at recurrence and 4 due to of lack of negativity between testing, leaving 5 patients with 7 episodes of recurrent viremia to evaluate. At first recurrent viremia, 4 patients (80%) demonstrated resistant genotype; 1 patient had wild type. Two patients went on to have a second viremia recurrence; both demonstrated wild-type genotype, despite the fact that the first recurrence in these patients was resistant genotype. CONCLUSION: In transplant recipients with history of GR-CMV, it appears that there is strain variability in latency: repeat genetic testing in patients with recurrent viremia after GR-CMV should be conducted. In the setting of wild-type repopulation, use of GCV should be considered. PMID- 29457492 TI - The Risk of Community-Acquired Enteric Infection in Proton Pump Inhibitor Therapy: Systematic Review and Meta-analysis. AB - BACKGROUND: Previous meta-analyses suggest that users of proton pump inhibitors (PPIs) have a higher risk of developing enteric infections compared with nonusers. These previous meta-analyses have considerable heterogeneity, and it is not clear whether the effect of PPIs is different for different types of microorganisms. OBJECTIVE: The aim of this study is to update previous meta analyses, concentrating on enteric infection in community settings and exploring potential sources of heterogeneity. METHODS: A systematic search was conducted on electronic databases (all available years until November 2017). PubMed, EMBASE, Cochrane, and Web of Science were searched using specific keywords related to PPI therapy and community-acquired enteric infection. Eligible studies were selected based on prespecified criteria. RESULTS: A total of 9 observational studies evaluating community-acquired enteric infection were eligible, including 12 separate analyses. The meta-analysis showed that PPI users have an increased risk of developing community-acquired enteric infection (pooled odds ratio [OR] = 4.28; 95% CI = 3.01-6.08). There was significant heterogeneity between the studies ( I2 = 85%; P < 0.001), which was partly explained by type of microorganism. The strength of the association was similar for Salmonella (pooled OR = 4.84; 95% CI = 2.75-8.54; I2 = 58.7%; P = 0.064) and Campylobacter (pooled OR = 5.09; 95% CI = 3-8.64; I2 = 81%; P < 0.001) but lower for studies that combined all bacteria (pooled OR = 2.42; 95% CI = 0.96-6.14; I2 = 94.3%; P < 0.001). CONCLUSION: PPI users have an increased risk of developing community acquired enteric infections compared with nonusers. The heterogeneity was partially explained by type of microorganism; the association is stronger for Salmonella and Campylobacter than for all bacteria combined. PMID- 29457491 TI - Critical Care Pharmacists and Medication Management in an ICU Recovery Center. AB - BACKGROUND: Many patients experience complications following critical illness; these are now widely referred to as post-intensive care syndrome (PICS). An interprofessional intensive care unit (ICU) recovery center (ICU-RC), also known as a PICS clinic, is one potential approach to promoting patient and family recovery following critical illness. OBJECTIVES: To describe the role of an ICU RC critical care pharmacist in identifying and treating medication-related problems among ICU survivors. METHODS: A prospective, observational cohort study was conducted of all outpatient appointments of a tertiary care hospital's ICU-RC between July 2012 and December 2015. The pharmacist completed a full medication review, including medication reconciliation, interview, counseling, and resultant interventions, during the ICU-RC appointment. RESULTS: Data from all completed ICU-RC visits were analyzed (n = 62). A full medication review was performed in 56 (90%) of these patients by the pharmacist. The median number of pharmacy interventions per patient was 4 (interquartile range = 2, 5). All 56 patients had at least 1 pharmacy intervention; 22 (39%) patients had medication(s) stopped at the clinic appointment, and 18 (32%) patients had new medication(s) started. The pharmacist identified 9 (16%) patients who had an adverse drug event (ADE); 18 (32%) patients had ADE preventive measures instituted. An influenza vaccination was administered to 13 (23%) patients despite an inpatient protocol to ensure influenza vaccination prior to discharge. A pneumococcal vaccination was administered to 2 (4%) patients. CONCLUSIONS: Use of a critical care pharmacist resulted in the identification and treatment of multiple medication-related problems in an ICU-RC as well as implementation of preventive measures. PMID- 29457493 TI - Impact of Vitamin D Supplementation on Attention-Deficit Hyperactivity Disorder in Children. AB - BACKGROUND: The role of nutrients and dietary factors in attention-deficit hyperactivity disorder (ADHD) remains unclear. OBJECTIVES: The primary objective was to evaluate the serum vitamin D level in children with a diagnosis of ADHD. The secondary objective was to detect the effect of vitamin D supplementation on cognitive function in those with vitamin D deficiency. METHODS: A total of 50 children with ADHD and 40 healthy controls were included in the study. We measured the serum level of vitamin D. Patients with vitamin D deficiency were subdivided into 2 groups: one with vitamin D supplementation and the other without vitamin D supplementation. Further assessment and follow-up of children with ADHD was done. The Wisconsin Card Sorting Test, Conners' Parent Rating Scale, and Wechsler Intelligence Scale for Children were performed at baseline and follow-up in all cohorts with an ADHD diagnosis. RESULTS: The diagnosis of vitamin D deficiency was significantly greater in children with ADHD compared with the control group ( P < 0.05). Children with ADHD had significantly ( P = 0.0009) lower values of serum vitamin D (17.23 +/- 8.98) than the control group(31.47 +/- 14.42). The group receiving vitamin D supplementation demonstrated improvement in cognitive function in the conceptual level, inattention, opposition, hyperactivity, and impulsivity domains. CONCLUSION: Vitamin D supplementation in children with ADHD may improve cognitive function. PMID- 29457494 TI - Management of Phenobarbital and Apixaban Interaction in Recurrent Cardioembolic Stroke. PMID- 29457495 TI - Effects of Initial Body Mass Index and Weight Change on All-Cause Mortality: A 10 Year Cohort Study in Korea. AB - We evaluated the effects of baseline body mass index (BMI) and its changes over 4 years on all-cause mortality in Korean population. We analyzed 351 735 participants whose BMI was measured in both 2002/2003 and 2006/2007. Mortality was assessed until 2013. Multivariate hazard ratios for all-cause mortality were estimated. Underweight and severe obesity with BMI >30 kg/m2 were significantly associated with higher mortality. Similarly, >5% decrease or >10% increase of BMI for 4 years was associated with the increased risk of death. Comparing the results between baseline BMI and BMI change, the BMI change showed more stable associations with mortality than the baseline BMI in subgroup analysis such as nonsmokers and healthy participants. This study suggests that BMI change could be a useful health indicator along with obesity level by BMI. In addition, maintaining a healthy weight is needed for longevity, but rapid weight change should be carefully monitored. PMID- 29457496 TI - Prostate Cancer Risk Reduced by Physical Activity Even Among Men With Prolonged Sitting Time: A Study From Vietnam. AB - Increasing prostate cancer incidence in the Asia-Pacific region may be related to a more sedentary lifestyle resulted from economic growth and rapid urbanization. The present case-control study of 640 men aged 64 to 75 years was conducted in Vietnam between 2013 and 2015 to ascertain the relationship between physical activity and prostate cancer risk, accounting for the duration of sitting time. Reduced prostate cancer risks were found for men engaging in medium (15.8-47.3 metabolic equivalent task [MET]-h/week) and high (>47.3 MET-h/week) physical activity levels, with the adjusted odds ratios being 0.52 (95% confidence interval = 0.35-0.77) and 0.27 (95% confidence interval = 0.14-0.49), respectively. This association was independent of sitting time. Analyses of joint association of physical activity and sitting time also found a reduction in the cancer risk for higher energy expenditure levels. Similar results were evident for both low-medium and high grade tumors. The findings are important for developing health strategies to prevent prostate cancer in Asian countries. PMID- 29457497 TI - Prevalence and Demographic Correlates of Overweight, Physical Activity, and Screen Time Among School-Aged Children in Urban China: The Shanghai Study. AB - This study reports the prevalence and demographic correlates of overweight, as well as meeting physical activity and screen time guidelines, in Chinese children. A representative sample of school-aged children ( n = 49 549) in Shanghai were participants. Children's anthropometrics were objectively measured; their physical activity and screen time, and demographic variables including age, sex, skill proficiency, sport affiliation, and transportation mode were self reported. Multivariate logistic regression analyses were conducted. The prevalence of overweight was 24.9%, meeting physical activity guidelines was 20.5%, and meeting screen time guidelines was 73.5%. Boys (odds ratio [OR] = 1.60, 95% confidence interval [CI] = 1.50-1.71) had higher overweight prevalence than girls. Girls (OR = 0.91, 95% CI = 0.85-0.97) and those without sport affiliation (OR = 0.48, 95% CI = 0.42-0.54) were less likely to meet physical activity recommendations than their counterparts. Girls were more likely than boys to meet screen time recommendations (OR = 1.29, 95% CI = 1.22-1.37). Children's sex, sport affiliation, and skill proficiency are factors that policymakers can use to improve body weight status, physical activity participation, and screen time. PMID- 29457498 TI - Factors Associated With Maternal Depression in the Maldives: A Prospective Cohort Study. AB - The aim of the study was to document perinatal depression in mothers in the Maldives and associated factors. A cohort of 458 mothers was recruited at the 2 major hospitals in Male, the Maldives, and followed from 36 weeks of pregnancy to 3 months after birth. The Edinburgh Postnatal Depression Scale (EPDS) was used to measure maternal depression. Maternal sociodemographic factors and infant's health were also recorded. The prevalence of depressive symptoms (EPDS score >=13) at 36 weeks of pregnancy and at 1 and 3 months postpartum were 24%, 27%, and 12%, respectively. Having experienced stressful life events is an established risk factor for maternal depression across these time points. Having depressive symptoms during the postpartum period is significantly associated with presence of antenatal depressive symptoms. Future studies may look into effectiveness of strategies that cope with stressors in the management of maternal depression. PMID- 29457499 TI - Factors Related to Alcohol Consumption Among Japanese Physicians. AB - This study aimed to investigate the drinking habits of Japanese physicians, and clarify their causal factors. A self-administered questionnaire was sent to 6000 male and 1500 female physicians, selected from among members of the Japan Medical Association. We analyzed the correlation of drinking habits with age, medical department, smoking and exercise status, work environment, sleep problems, and mental health. The response rate was 79.4%. Physicians with a heavy drinking habit were most frequently men in their 60s and women in their 20s to 50s. Drinking or heavy drinking tendencies decreased with increasing age. Smoking status was correlated with heavy drinking. Exercise status was correlated with drinking among men, and drinking/heavy drinking among women. Mental health was not correlated with drinking habit. However, sleep problems were correlated with a heavy drinking habit. These results suggest that countermeasures need to be taken to decrease the rate of heavy drinking among physicians. PMID- 29457505 TI - Death after bite from severed snake head.

Their structures were elucidated by spectroscopic methods, including 1D and 2D NMR spectroscopy. The isolated compounds exhibited slightly antioxidant activities through DPPH and ABTS radical scavenging assays but showed no antibacterial activity against Streptococcus mutans ATCC2517, a dental caries causing bacteria. PMID- 29457507 TI - Whom Do You Trust. PMID- 29457508 TI - Integrative Review of Mobile Phone Contacts and Medication Adherence in Severe Mental Illness. AB - BACKGROUND: Poor medication adherence is a significant problem in individuals with severe mental illness (SMI). About 50% of people with SMI become nonadherent to treatment in the first month following discharge from the hospital. OBJECTIVE: This study examined literature in the past decade (2006-2016) on the use of mobile phone contacts in individuals with SMI to improve medication adherence post hospital discharge. DESIGN: This integrative review used the search terms texting, text messaging, SMS, cell/mobile phone, medication adherence, medication compliance, and mental illness. Databases (CINAHL, PubMed, PsycINFO, and Scopus) and manual searching of reference lists were done. The main inclusion criteria were the use of mobile phone contacts on medication adherence in individuals with SMI. Adults 18 years and older, studies conducted from 2006 to 2016, and studies conducted in English were also criteria for inclusion. Only five studies met criteria for inclusion. RESULTS: Outcomes from the review showed that mobile phone contacts have been used to improve medication adherence in individuals with SMI and able to provide the four types of social support (instrumental, informational, emotional, and, appraisal). When phone contacts especially text messaging was used as an adjunct to other interventions, it yielded better medication adherence than when used alone. However, results on medication adherence rates were mixed in participants on both psychiatric and nonpsychiatric medications. CONCLUSION: Although mobile phone contacts are a promising tool to enhance medication adherence after hospital discharge, its effectiveness to increase medication adherence in this population remains inconclusive. PMID- 29457509 TI - Evidence-based practice self-efficacy of undergraduate speech pathology students following training. AB - AIM: The aims of this study were to determine the self-efficacy of speech pathology students in conducting evidence-based practice before and after a comprehensive evidence-based practice course, and the impact of timing of the course (Semester 1/2). METHOD: Students attended a 13-week course in their final year of study. The evidence-based practice confidence scale (EPIC) was used to measure the students' self-efficacy pre- and post-training. RESULTS: Ninety-two percent of students enrolled over six semesters participated. Students began the evidence-based practice course with high confidence in asking patients their preferences but low confidence in interpreting and analysing statistics. A significant improvement in confidence in all evidence-based practice areas was found, with greatest improvement occurring in the critical appraisal of research. Overall, the teaching had greatest effect on a group of skills for finding valid EBP information. There were significant differences between semester one and two students in only 18% of responses. Semester two students were more confident in half of these responses. CONCLUSIONS: An evidence-based practice course made a significant difference to student self-efficacy across all aspects, with few differences related to timing of the course. Implications are discussed. Implications for Rehabilitation Health professionals must be confident implementing evidence-based practice throughout the course of their careers, as best practice changes over time. A capstone unit of study/course for undergraduate speech pathology students significantly improved their self efficacy in implementing evidence-based practice. This has positive implications for evidence-based practice across a wide range of clinical settings including rehabilitation and disability as the graduate entry level students enter the workforce. For on-going success, graduate entry level students must continue to implement evidence-based practice as clinicians if they are to maintain their confidence and further develop their skill set.

AB - This project quantified the impact that voluntary reformulation efforts of the food industry had on the Irish population's nutrient intake. Nutrient composition data on reformulated products were collected from 14 major food companies for two years, 2005 and 2012. Probabilistic intake assessments were performed using the Irish national food consumption surveys as dietary intake data. The nutrient data were weighted by market shares replacing existing food composition data for these products. The reformulation efforts assessed, significantly reduced mean energy intakes by up to 12 kcal/d (adults), 15 kcal/d (teens), 19 kcal/d (children) and 9 kcal/d (pre-schoolers). Mean daily fat intakes were reduced by up to 1.3 g/d, 1.3 g/d, 0.9 g/d and 0.6 g/d, saturated fat intakes by up to 1.7 g/d, 2.3 g/d, 1.8 g/d and 1 g/d, sugar intakes by up to 1 g/d, 2 g/d, 3.5 g/d and 1 g/d and sodium intakes by up to 0.6 g/d, 0.5 g/d, 0.2 g/d, 0.3 g/d for adults, teenagers, children and pre-school children, respectively. This model enables to assess the impact of industry reformulation amongst Irish consumers' nutrient intakes, using consumption, food composition and market share data. PMID- 29457510 TI - Hepatocellular carcinoma abutting large vessels: comparison of four percutaneous ablation systems. AB - PURPOSE: To compare overall local tumour progression (OLTP), defined as the failure of primary ablation or local tumour progression, with single applicator monopolar radiofrequency ablation (RFA), microwave ablation (MWA), cluster-RFA and multi-bipolar radiofrequency (mbpRFA) in the treatment of hepatocellular carcinoma (HCC) <= 5 cm abutting large vessels (>=3 mm). MATERIALS AND METHODS: This multicenter, retrospective, per-nodule study was performed from 2007 to 2015. The study was approved by the ethics review board, and informed consent was waived. A total of 160/914 HCC nodules treated by thermal ablation and abutting large vessels (40 per treatment group) treated by monopolar RFA, MWA, cluster-RFA or mbpRFA were matched for tumour size, alpha-feto-protein level and vessel size. OLTP rates were compared by the log-rank test and the multivariate Cox model after matching. RESULTS: No differences were observed in tumour size, vessel size or alpha-feto-protein levels among the three groups (p = 1). The cumulative 4 year OLTP rates following monopolar RFA, cluster-RFA, multi-bipolar RFA and MWA were 50.5%, 16.3%, 16.3% and 44.2%, respectively (p = 0.036). On multivariate Cox regression, vessel size >=10 mm, monopolar RFA and MWA were independent risk factors of OLTP compared to cluster-RFA or mbpRFA. CONCLUSION: Multi-applicator RFA provides better local tumour control in HCC abutting large vessels than single-applicator techniques (monopolar RFA or MWA). PMID- 29457512 TI - Perceived Diet and Exercise Behaviors Among Social Network Members With Personal Lifestyle Habits of Public Housing Residents. AB - Our objective was to characterize the relationship between public housing residents' diet/exercise habits with similar behaviors among their social network. We conducted a cross-sectional survey of randomly selected households in Baltimore, Maryland, from August 2014 to August 2015. Adult heads of household completed questions on diet, exercise, and perceived habits among network members. Our dependent variables were high added sugar intake (>=39.9 teaspoons/day), high fruit/vegetable intake (>=6.1 servings/day), and being physically active (>=moderately activity). Our network exposures were proportion of members perceived to daily consume (1) sugar-sweetened beverages, (2) sweets, (3) fruits, and (4) vegetables, as well as to weekly exercise (1) vigorously or (2) moderately. We used multivariate logistic regression to examine associations between habits with relevant network exposures. Our sample included 266 adults with mean age of 44.5 years, 86.1% women and 95.5% African American. We found a statistically significant association between study participants' high daily intake of added sugar with perceived network exposure to daily sugar-sweetened beverages (odds ratio [OR] = 1.10, 95% confidence interval [CI] [1.02, 1.20]) and daily sweets (OR = 1.10, 95% CI [1.02, 1.20]). Greater network exposure to weekly vigorous exercise was significantly associated with personally being physically active (OR = 1.15, 95% CI [1.04, 1.28]), but not network exposure to weekly moderate exercise. Among public housing residents, associations exist between individuals' and perceived networks' lifestyle habits of high added sugar foods consumption and vigorous exercise, which may hold promise for future social network interventions. PMID- 29457513 TI - Qualifying the difficulty of embryo transfer with a visual analogue scale and assessing its impact on IVF outcomes. AB - The aim of this study was to determine whether a continuous visual analogue scale (VAS) is a reliable tool to grade embryo transfer (ET) difficulty when assessing IVF outcomes. No standardized grading system exists for reporting ET 'difficulty' which is typically recorded in descriptive terms. Clinicians performing 188 fresh single ETs between November 2014 and May 2016 also recorded a VAS score (0-100). Embryo transfers were stratified into three levels of ET 'difficulty': (A) 'easy' - no resistance; (B) 'medium' - resistance overcome by advancing the catheter's outer sheath; and (C) 'difficult' - a malleable stylet was required to overcome resistance; and these compared to the VAS scores. Clinical pregnancy and live birth rates were the primary outcomes. VAS scores were categorized into four incremental groupings according to the 25th, 50th and 75th percentiles (Groups 1 4) for analysis. No significant relationship (p > 0.05) was seen in clinical pregnancy or live birth rates in either the standard difficulty or the VAS groupings. The median VAS scores in Groups A-C increased as difficulty increased, but the interquartile ranges overlap with wide clinician variation, suggesting the VAS is not itself a reliable enough tool to record ET difficulty in isolation. PMID- 29457514 TI - Relapse of bullous pemphigoid: an update on this stubborn clinical problem. AB - Bullous pemphigoid (BP) is a chronic autoimmune blistering disorder that has a predilection for the elderly. It is characterized by a poor prognosis due to its high mortality rate and the tendency to relapse. The relapse rate of BP ranges from 27.87% to 53% after disease remission, while the majority of relapses occur early (within 6 months) during remission. Clinical interventions aimed to prevent early relapses could reduce potential complications from first-line treatment and make follow-up care easier for clinicians in practice, thus improving the prognosis of BP and the quality of patients' lives. In this article, we attempt to review previous studies from the medical literature concerning relapse and risk factors related to relapse in BP patients. Treatments found to be able to reduce or increase relapse rate were also discussed. We propose that clinicians be aware of these risk factors and manage proper treatment accordingly. Key Messages * The relapse rate of bullous pemphigoid ranges from 27.87% to 53% after disease remission, while the majority of relapses occur early (within 6 months) during remission. * Ageing, disease severity, neurological disorder, serum ECP, BAFF, IL-17, IL-23, CXCL10 and anti-BP180 antibody levels have been shown to be related to relapse, while confirmation studies are needed before using them for guidance for relapse prevention. * Longer usage of corticosteroid with a low dose, combination of immunosuppressants and intravenous immunoglobulin are helpful in lowering relapse rate.

PMID- 29457516 TI - Effects of chocolate-based products intake on blood glucose, insulin and ghrelin levels and on satiety in young people: a cross-over experimental study. AB - This cross-over experimental study aimed to examine the effects of filled chocolate consumption on blood glucose, insulin and ghrelin levels in 20 volunteers. After a one-week run-in period, study participants consumed two chocolate-based products, the tested biscuit or water for 21 days as a morning snack. After a two-week wash-out period, participants consumed another tested food for another 21 days. Each participant consumed all four test foods within an 18-week period. The participants' blood insulin increased slowly after two chocolate-based products intakes on the first day and satiety levels after eating chocolate-based products and the tested biscuit were the same. Chocolate consumption for three weeks had no adverse effects on blood glucose, insulin or ghrelin levels. In conclusion, compared to eating the tested biscuit, 21-day consumption of the tested chocolate-based products had no adverse effects on the blood glucose, insulin and ghrelin levels. This trial is registered with chictr.org.cn: ChiCTR-IOR-16009525. PMID- 29457517 TI - The protection of resveratrol and its combination with glibenclamide, but not berberine on the diabetic hearts against reperfusion-induced arrhythmias: the role of myocardial KATP channel. AB - CONTEXT: Cardiovascular dysfunctions such as life-threatening arrhythmias are one of the main reasons of mortality and morbidity in diabetic patients Objective: We aimed to investigate the long-term effects of resveratrol, berberine and glibenclamide combinations on the ischemia/reperfusion (I/R) induced arrhythmias in streptozotocin (STZ)-induced diabetic rats and to investigate the role of myocardial KATP channel in the possible anti-arrhythmic actions of the treatments. METHODS: Two days after induction of diabetes, diabetic rats were treated with resveratrol [5 mg/kg, intraperitoneally (i.p.)], berberine (10 mg/kg, i.p) and glibenclamide (5 mg/kg, i.p) for 6 weeks. On the 43th day, experimental animals were subjected to 6-min ischemia and 6-min reperfusion in vivo. RESULTS: The protein expression of Kir6.2 subunits was downregulated in the diabetic hearts. However, all drug treatments restored the protein expression of Kir6.2 subunits. Resveratrol alone and its combination with glibenclamide decreased the arrhythmia score, the arrhythmic period and the incidence of other types of arrhythmias during the reperfusion period. CONCLUSIONS: The combination of resveratrol with glibenclamide may alleviate reperfusion-induced arrhythmias via an underlying mechanism not be only associated with the restoration of the protein expression of Kir6.2 subunits but also associated with the other subunits or ion channels underlying cardiac action potential.

AB - A new homoisoflavonoid, (3R)-5,7-dihydroxy-6-methyl-3-(2'-hydroxy-4' methoxybenzyl)-chroman-4-one (1), namely polygonatone H, in addition to fourteen known homoisoflavones (2-15) were isolated from the rhizome of Polygonatum Cyrtonema Hua. The structures were identified with the aid of 1D/2D NMR spectroscopic technologies. Compounds 2, 6, 8, 10, 11, 13, and 15 were isolated from P. Cyrtonema for the first time. Compound 1 showed cytotoxicities to human cancer cell lines with IC50 values to comparable those of cisplatin. PMID- 29457518 TI - Surface modification of doxorubicin-loaded nanoparticles based on polydopamine with pH-sensitive property for tumor targeting therapy. AB - One major challenge of current surface modification of nanoparticles is the demand for chemical reactive polymeric layers, such modification is always complicated, inefficient, and may lead the polymer lose the ability to encapsulate drug. To overcome this limitation, we adopted a pH-sensitive platform using polydopamine (PDA) as a way of functionalizing nanoparticles (NPs) surfaces. All this method needed to be just a brief incubation in weak alkaline solution of dopamine, which was simple and applicable to a variety of polymer carriers regardless of their chemical reactivity. We successfully conjugated the doxorubicin (DOX)-PDA-poly (lactic-co-glycolic acid) (PLGA) NPs with two typical surface modifiers: folate (FA) and a peptide (Arg-Gly-Asp, RGD). The DOX-PDA-FA NPs and DOX-PDA-RGD-NPs (targeting nanoparticles) were characterized by particle size, zeta potential, and surface morphology. They were quite stable in various physiological solutions and exhibited pH-sensitive property in drug release. Compared to DOX-NPs, the targeting nanoparticles possessed an excellent targeting ability against HeLa cells. In addition, the in vivo study demonstrated that targeting nanoparticles achieved a tumor inhibition rate over 70%, meanwhile prominently decreased the side effects of DOX and improve drug distribution in tumors. Our studies indicated that the DOX-PLGA-NPs modified with PDA and various functional ligands are promising nanocarriers for targeting tumor therapy. PMID- 29457521 TI - Relationships Between Race/Ethnicity and Health Care Utilization Among Older Post Acute Home Health Care Patients. AB - Few studies have explored racial/ethnic differences in health care outcomes among patients receiving home health care (HHC), despite known differences in other care settings. We conducted a retrospective cohort study examining racial/ethnic disparities in rehospitalization and emergency room (ER) use among post-acute patients served by a large northeastern HHC agency between 2013 and 2014 ( N = 22,722). We used multivariable binomial logistic regression to describe the relationship between race/ethnicity and health care utilization outcomes, adjusting for individual-level factors that are conceptually related to health service use. Overall rates of rehospitalization and ER visits were 10% and 13%, respectively. African American and Hispanic patients experienced higher odds of ER visits or rehospitalization during their HHC episode. Racial/ethnic differences in utilization were mediated by enabling factors, such as caregiver availability, and illness-level factors, such as illness severity, functional status, and symptoms. Intervention targets may include early risk assessment, proactive management of clinical conditions, rehabilitative therapy, and caregiver training. PMID- 29457520 TI - Caregiver Reactions to Aggressive Behaviors in Persons With Dementia in a Diverse, Community-Dwelling Sample. AB - PURPOSE: To describe caregiver challenges with and confidence managing three aggressive behavior types in persons with dementia: verbal aggression, destroying property, and threatening to hurt others. DESIGN AND METHOD: Secondary analysis of baseline data from the 2001-2004 Resources for Enhancing Alzheimer's Caregiver Health II (REACH II) initiative. RESULTS: One or more aggressive behaviors within 1 week were reported by more than a third of caregivers, with most expressing upset but fewer expressing confidence managing the behaviors. Caregiver distress and confidence differed by race/ethnicity in response to verbal aggression, with more White/Caucasian caregivers expressing upset than Hispanic/Latinos or Black/African Americans. Fewer Hispanic/Latinos expressed confidence managing verbal aggression, compared with White/Caucasians or Black/African Americans. DISCUSSION: Aggressive behaviors challenge caregivers, with reactions varying by behavior type and race/ethnicity. Cultural and contextual factors suggest the need to tailor interventions, especially skill-building interventions that increase confidence managing aggressive behaviors while decreasing upset. PMID- 29457522 TI - A high prevalence of TMD is related to somatic awareness and pain intensity among healthy dental students. AB - OBJECTIVE: Dental students have been identified as a group with high risks of developing both temporomandibular disorders (TMD) and psychosocial conditions. Our primary aim was to evaluate the cross-sectional prevalence of TMD diagnoses, as defined in the Diagnostic Criteria (DC)/TMD, among dental students. The secondary aim was to evaluate the prevalence and association of behavioural and psychosocial factors in relation to DC/TMD diagnoses. MATERIALS AND METHODS: The study was conducted among undergraduate dental students during the second semester of their third year at the Department of Odontology, Medical Faculty, Umea University, Sweden. Three consecutive cohorts were recruited during August in 2013, 2014, 2015. In total, 54 students were included and examined according the DC/TMD procedure. RESULTS AND CONCLUSIONS: The prevalence of any DC/TMD diagnosis was 30%. The most prevalent TMD diagnosis was myalgia. Individuals with a TMD-pain diagnosis (i.e. myalgia or arthralgia) reported significantly higher pain intensity levels according to the Graded Chronic Pain Scale (GCPS) as compared to individuals without TMD-pain (Fisher's exact test p < .001, two sided). In addition, individuals with any TMD scored significantly higher jaw functional limitations according to the Jaw Functional Limitation Scale 20 (JFLS 20, p < .001) and oral parafunctions according to the Oral Behavior Checklist (OBC, p = .005) as compared to individuals without TMD. The psychosocial factors evaluated did not differ between individual with or without a TMD diagnosis. The majority of the dental students reported symptoms that are already identified as risk factors for developing TMD and pain conditions. However, longitudinal data are needed to evaluate how this evolves over time. PMID- 29457523 TI - Natural products for controlling hyperlipidemia: review. AB - Hyperlipidemia is an abnormality of lipid metabolism, characterized by an elevation of total cholesterol, triglyceride, and low density lipoprotein cholesterol, and/or a decreasing of high density lipoprotein cholesterol in circulating levels. Hyperlipidemia has been ranked as one of the greatest risk factors contributing to prevalence and severity of coronary heart diseases. Hyperlipidemia-associated lipid disorders are considered the cause of atherosclerotic cardiovascular disease. There has been a growing interest in natural products and their role in the maintenance and improvement of health and wellness. The cholesterol-lowering effect of dietary plants has been well studied and various natural products were shown to be helpful in lowering plasma cholesterol levels and encouraging safety profile. The main focus of this review is to describe what we know to date of natural products, along with their lipid lowering mechanisms, which are either through inhibition of cholesterol absorption, inhibition of cholesterol synthesis or antioxidant mechanisms. PMID- 29457524 TI - Safety and effect on ablation size of hydrochloric acid-perfused radiofrequency ablation in animal livers. AB - PURPOSE: Our objective was to determine the safety and ablation size of hydrochloric acid-perfused radiofrequency ablation (HCl-RFA) in liver tissues, prospectively using in vivo rabbit and ex vivo porcine liver models. MATERIALS AND METHODS: The livers in 30 rabbits were treated in vivo with perfusions of normal saline (controls) and HCl concentrations of 5%, 10%, 15%, and 20%, during RFA at 103 degrees C and 30 W for 3 min. For each experimental setting, six ablations were created. Safety was assessed by comparing baseline weight and selected laboratory values with those at 2, 7, and 14 days' post-ablation, and by histopathological analysis. The livers in 25 pigs were treated ex vivo with the same five perfusions during RFA at 103 degrees C, at both 30 W and 60 W, for 30 min. Ablation diameters and volumes were measured by two examiners. RESULTS: Rabbit weights and selected laboratory values did not differ significantly from baseline to 7 and 14 days' post-ablation, liver tissues outside the ablation zones were normal histologically, and adjacent organs showed no macroscopic damage. The mean ablation volumes in the porcine livers treated with HCl-RFA were all larger than those treated with normal saline perfusion during RFA (NS-RFA), at both 30 W and 60 W (p < 0.001). The largest ablation volume and transverse diameter were observed in the porcine livers during 10% HCl-RFA at 60 W, measuring 179.22 (SD = 24.79) cm3 and 6.84 (SD = 0.36) cm, respectively. CONCLUSIONS: Based on our experiments, HCl-RFA in the liver appears to be as safe as NS-RFA while also resulting in larger ablation zones. PMID- 29457525 TI - Interleukin-1beta induces apoptosis in annulus fibrosus cells through the extracellular signal-regulated kinase pathway. AB - PURPOSE: The loss of intervertebral disc (IVD) cells due to excessive apoptosis induced by inflammatory cytokines is a major cause of IVD degeneration. This study aims to explore the mechanism of interleukin-1beta (IL-1beta)-induced apoptosis of annulus fibrosus cells (AFCs). It's hypothesized that IL-1beta induces apoptosis through the extracellular signal-regulated kinase (ERK) pathway in AFCs. METHODS: The mRNA and protein expression levels of apoptosis-associated genes were analyzed by quantitative real-time PCR and Western blotting. The apoptotic rate was measured by flow cytometry. Three experimental groups were established, including Control, IL-1beta, and IL-1beta+U0126 groups, respectively. RESULTS: Increase in the expression of apoptosis-associated genes including B-cell lymphoma-2 associated X (Bax), caspase-3, and caspase-9, and meanwhile, decrease in the expression of B-cell lymphoma-2 (Bcl-2) gene were found in patients with degenerative IVDs. In in vitro tests, both apoptosis and phosphorylated ERK expression in rat AFCs decreased in the IL-1beta+U0126 group compared with the IL-1beta group. The expression levels of Bax, caspase-3, and caspase-9 in AFCs decreased significantly in the IL-1beta+U0126 group compared with those in the IL-1beta group. The expression level of Bcl-2, on the other hand, significantly increased. CONCLUSIONS: Findings from this study suggest that IL-1beta induces apoptosis in AFCs through the ERK pathway, and therefore, ERK inhibition may provide certain protection against the adverse effects of IL 1beta.

AB - Variation of fetal hemoglobin (Hb F) expression in heterozygous Hb E (HBB: c.79G>A) individuals is associated with several genetic modifiers and not well understood. This study was undertaken in order to determine the effect of single nucleotide polymorphisms (SNPs), including XmnI Ggamma (rs7482144), rs766432 on the BCL11A gene and rs9376074 on the HBS1L gene, on Hb F levels in Southern Thai heterozygous Hb E individuals. A total of 97 Southern Thai subjects carrying heterozygous Hb E were selected for the hematological study. After excluding the samples with alpha-thalassemia (alpha-thal) interaction or moderate anemia, because both conditions can affect the hematological parameters, the remaining 74 samples were submitted to SNP analysis. Hematological parameters were measured using an automated hematology analyzer and high performance liquid chromatography (HPLC). The results show that rs766432 was strongly associated with increased Hb F levels and rs7482144 was associated with Hb F levels in each subgroup (genotype) of rs766432. This study suggested that the BCL11A locus has a major effect on Hb F levels compared with the XmnI polymorphism in Hb E heterozygotes. This association of Hb F levels with SNPs is useful for the interpretation of hemoglobin (Hb) typing in heterozygous Hb E samples with high Hb F levels. Future research will need to address the better understanding of the mechanisms of the SNPs that regulate Hb F production without stress erythropoiesis in Hb E heterozygotes. PMID- 29457530 TI - A new insight into the classification of dusky thrush complex: bearings on the phylogenetic relationships within the Turdidae. AB - Dusky thrush complex comprises of two sister species breeding in SC Siberia, which is the member of thrush Turdus from Turdidae. The phylogenetic resolution of Dusky thrush complex remains controversial, and a detailed research is still necessary. In this research, we determined the complete mtDNAs of both species, and estimated phylogenetic trees based on the mtDNA alignment of these and 21 other Turdidae species, to clarify the taxa status of the Dusky thrush complex. The squenced lengths of these three mitochondrial genomes were 16,737, 16,788 and 16,750 bp. The mtDNAs are circular molecules, containing the 37 typical genes, with an identical gene order and arrangement as those of other Turdidae. The ATG and TAA, respectively, are observed the most commonly start and stop codon. Most of the tRNA could be folded into the canonical cloverleaf secondary structure except for tRNASer (AGY) and tRNALeu (CUN), which lose 'DHU' arm. The control region presented a higher A + T content than the average value for the whole mitogenome. The phylogenetic trees reconstructed by the concatenated nucleotide sequences of mtDNA genes (Cyt b, ND2 and COI) indicate the Dusky thrush complex cannot be divided into two species, but the relationships between Dusky thrush subspecies still need additional study. This study improves our understanding of mitogenomic structure and evolution of the Dusky thrush complex, which can provide further insights into our understanding of phylogeny and taxonomy in Turdidae. PMID- 29457529 TI - N-terminal-pro-B-type-natriuretic peptide associated with 2-year mortality from both cardiovascular and non-cardiovascular origins in prevalent chronic hemodialysis patients. AB - N-terminal-pro-B-type-natriuretic peptide (NT-proBNP) was a predictive marker of cardiovascular disease (CVD)-related death in chronic dialysis patients. NT proBNP was also correlated with markers of inflammation, malnutrition and protein energy wasting. We hypothesized whether NT-proBNP was also associated with non CVD death in chronic dialysis patients. A prospective observational study for incidence of death in chronic dialysis patients was conducted. Prevalent chronic dialysis patients (n = 1310) were enrolled and followed for 24 months. One hundred forty-four deaths were recorded. Area under the curve using ROC analysis for NT-proBNP showed: all causes of death (0.761), CVD-related (0.750), infection and malignancy-related (0.702) and others and unknown (0.745). After adjusting for age, sex, hemodialysis vintage, cardiothoracic ratio, mean pre-dialysis systolic blood pressure, dry weight and basal kidney disease, the hazard ratios (95% confidence intervals) per 1-log NT-proBNP calculated using multivariate Cox analysis were: all causes of death, 3.83 (2.51-5.85); CVD-related, 4.30 (2.12 8.75); infection and malignancy-related, 2.41 (1.17-4.93); and others and unknown origin, 5.63 (2.57-12.37). NT-proBNP was significantly associated not only with CVD-relate but also with non-CVD-related deaths in this population of prevalent chronic dialysis patients. PMID- 29457531 TI - Shedding new light on RhoA signalling as a drug target in vivo using a novel RhoA FRET biosensor mouse. AB - The small GTPase RhoA is a master regulator of signalling in cell-extracellular matrix interactions. RhoA signalling is critical to many cellular processes including migration, mechanotransduction, and is often disrupted in carcinogenesis. Investigating RhoA activity in a native tissue environment is challenging using conventional biochemical methods; we therefore developed a RhoA FRET biosensor mouse, employing the adaptable nature of intravital imaging to a variety of settings. Mechanotransduction was explored in the context of osteocyte processes embedded in the calvaria responding in a directional manner to compression stress. Further, the migration of neutrophils was examined during in vivo "chemotaxis" in wound response. RhoA activity was tightly regulated during tissue remodelling in mammary gestation, as well as during mammary and pancreatic carcinogenesis. Finally, pharmacological inhibition of RhoA was temporally resolved by the use of optical imaging windows in fully developed pancreatic and mammary tumours in vivo. The RhoA-FRET mouse therefore constitutes a powerful tool to facilitate development of new inhibitors targeting the RhoA signalling axis. PMID- 29457532 TI - Effects of real-time gait biofeedback on paretic propulsion and gait biomechanics in individuals post-stroke. AB - Objectives Gait training interventions that target paretic propulsion induce improvements in walking speed and function in individuals post-stroke. Previously, we demonstrated that able-bodied individuals increase propulsion unilaterally when provided real-time biofeedback targeting anterior ground reaction forces (AGRF). The purpose of this study was to, for the first time, investigate short-term effects of real-time AGRF gait biofeedback training on post-stroke gait. Methods Nine individuals with post-stroke hemiparesis (6 females, age = 54 +/- 12.4 years 39.2 +/- 24.4 months post-stroke) completed three 6-minute training bouts on an instrumented treadmill. During training, visual and auditory biofeedback were provided to increase paretic AGRF during terminal stance. Gait biomechanics were evaluated before training, and during retention tests conducted 2, 15, and 30 minutes post-training. Primary dependent variables were paretic and non-paretic peak AGRF; secondary variables included paretic and non-paretic peak trailing limb angle, plantarflexor moment, and step length. In addition to evaluating the effects of biofeedback training on these dependent variables, we compared effects of a 6-minute biofeedback training bout to a non-biofeedback control condition. Results Compared to pre-training, significantly greater paretic peak AGRFs were generated during the 2, 15, and 30 minute retention tests conducted after the 18-minute biofeedback training session. Biofeedback training induced no significant effects on the non-paretic leg. Comparison of a 6-minute biofeedback training bout with a speed-matched control bout without biofeedback demonstrated a main effect for training type, with greater peak AGRF generation during biofeedback. Discussion Our results suggest that AGRF biofeedback may be a feasible and promising gait training strategy to target propulsive deficits in individuals post-stroke.

AB - A rare case of clinical complication following a percutaneous coronary intervention is presented. A femoral vascular access was chosen to treat a coronary lesion with a stent implantation. This femoral vascular access, however, resulted in a pyogenic infection of the ipsilateral hip joint that was not properly diagnosed for an extended post-interventional period. The hip joint completely deteriorated before its underlying cause was identified. This case report illustrates the importance of recognizing potential endovascular complications independently of their frequency. PMID- 29457534 TI - Comparing Hydrogels for Human Nucleus Pulposus Regeneration: Role of Osmolarity During Expansion. AB - Hydrogels can facilitate nucleus pulposus (NP) regeneration, either for clinical application or research into mechanisms of regeneration. However, many different hydrogels and culture conditions for human degenerated NP have been employed, making literature data difficult to compare. Therefore, we compared six different hydrogels of natural polymers and investigated the role of serum in the medium and of osmolarity during expansion or redifferentiation in an attempt to provide comparators for future studies. Human NP cells of Thompson grade III discs were cultured in alginate, agarose, fibrin, type II collagen, gelatin methacryloyl (gelMA), and hyaluronic acid-poly(ethylene glycol) hydrogels. Medium containing fetal bovine serum and a serum-free (SF) medium were compared in agarose, gelMA, and type II collagen hydrogels. Isolation and expansion of NP cells in low compared to high osmolarity medium were performed before culture in agarose and type II collagen hydrogels in media of varying osmolarity. NP cells in agarose produced the highest amounts of proteoglycans, followed by cells in type II collagen hydrogels. The absence of serum reduced the total amount of proteoglycans produced by the cells, although incorporation efficiency was higher in type II collagen hydrogels in the absence than in the presence of serum. Isolation and expansion of NP cells in high osmolarity medium improved proteoglycan production during culture in hydrogels, but variation in osmolarity during redifferentiation did not have any effect. Agarose hydrogels seem to be the best option for in vitro culture of human NP cells, but for clinical application, type II collagen hydrogels may be better because, as opposed to agarose, it degrades in time. Although culture in SF medium reduces the amount of proteoglycans produced during redifferentiation culture, isolating and expanding the cells in high osmolarity medium can largely compensate for this loss. PMID- 29457535 TI - Examining Driving and Participation 5 Years After Traumatic Brain Injury. AB - Participation is often considered a primary goal of traumatic brain injury (TBI) rehabilitation, but little is known about the influence of driving on participation after TBI. The objective of this study was to examine the independent contribution of driving status to participation at 5 years post TBI, after controlling for demographic, psychosocial, and functional factors. Participants ( N = 2,456) were community-dwelling individuals with moderate to severe TBI, age 18 to 65 at time of injury, and enrolled in the TBI Model Systems (TBIMS) National Database (NDB). Hierarchical linear regressions for the dependent variable of participation at 5 years post TBI were performed. Findings showed that driving was a highly significant independent predictor of participation and was a stronger relative predictor of participation than FIM(r) Cognitive, FIM(r) Motor, and depression. The independent contribution of driving to participation suggests the need to develop evidenced-based occupational therapy assessments and interventions that facilitate safe engagement in the occupation of driving to address the long-term goal of improved participation.

AB - AIM: To estimate the heritability of the New Zealand Veterinary Association (NZVA) elbow phenotype, obtain estimated breeding values (EBV) for the worst elbow score and estimate the genetic trends for this trait in four populous breeds of dogs, using the records from the NZVA Canine Elbow Dysplasia Scheme database (1992-2013). METHODS: Overall, 4,070 elbow records from a pedigree of 11,311 dogs were available for animals scored between 1992 and 2013. The worst elbow score between the left and right elbows was identified for each dog and used for EBV analysis. Estimates of heritability and EBV for the elbow score of dogs from German Shepherd dog, Labrador Retriever, Golden Retriever and Rottweiler breeds were obtained using restricted maximum likelihood procedures with a within-breed linear animal model. The model included the fixed effects of sex and birth year, with age at scoring as a covariable, and the random effect of animal. Genetic trends for the worst-elbow score were calculated as the regression coefficient of the EBV, weighted by reliabilities, on year of birth. RESULTS: The estimates of heritability for worst-elbow score were 0.25 (SE 0.06) in German Shepherd dogs, 0.46 (SE 0.06) in Labrador Retrievers, 0.18 (SE 0.07) in Golden Retrievers and 0.29 (SE 0.11) in Rottweilers. The genetic trend for German Shepherd dogs was -0.0082 (SE 0.0015), for Labrador Retrievers was -0.0016 (SE 0.0016), for Golden Retrievers was -0.0033 (SE 0.0010) and for Rottweilers was 0.0070 (SE 0.0023) units per annum, which were different from zero (p<0.01) in all breeds except Labrador Retrievers. CONCLUSIONS AND CLINICAL RELEVANCE: A small but favourable response to selection was achieved by three of the four breeds in the study period; during which selection for elbow traits has been largely voluntary. While the magnitude of genetic change in terms of elbow units per annum may appear small, it must be remembered that elbow scoring grades only range from 0-3. Greater improvement may be possible if compulsory screening was a requirement for pedigree breeding stock, and if greater selection pressure were applied on the basis on an individual's EBV, rather than the worst-elbow score alone. The maintenance of an open registry, with transparency of EBV information made available to all breeders, may enhance selection intensity opportunities and potentially assist with the process and progress of breeding selection.

AB - BACKGROUND: We evaluated the effects of intravenous dexmedetomidine during spinal anesthesia on hemodynamics, respiratory rate, oxygen saturation, sedpain, and compared them with those of saline infusion. Sixty American Society of Anesthesiologists physical status I and II cases were randomly divided into two groups. Patients were connected to the monitor after premedication, and spinal anesthesia was administered. Sensory and motor blockades were assessed using pinprick test and Bromage scale, respectively. Group I received dexmedetomidine infusion and Group II received saline infusion. Throughout the infusion process, hemodynamic data, respiratory rate, oxygen saturation, sedation, pain, Bromage score, amnesia, bispectral index, and side effects were recorded. Postoperative hemodynamic measurements, oxygen saturation, sedation, pain scores were obtained. Sedation and pain were evaluated using the Ramsay and visual analog scales, respectively. Analgesics were administered in cases with high scores on the visual analog scale. Postoperative analgesic consumption, side effects, treatments were recorded. No significant differences were found between the groups with respect to oxygen saturation, respiratory rate, pain, and side effects in the intraoperative period. Time to onset of sensorial block, maximum sensorial block, onset of motor block, and maximum motor block; bispectral index values; and apex heartbeat until 80 min of infusion, systolic arterial blood pressure until 90 min, and diastolic arterial blood pressure until 50 min were lower, whereas amnesia and sedation levels were higher in dexmedetomidine group. Postoperative pain and analgesic requirement were not different. Apex heartbeat at 15 min and systolic arterial blood pressure at 30 min were lower and sedation scores were higher in the dexmedetomidine infusion group. We demonstrated dexmedetomidine infusion had a hemodynamic depressant effect intraoperatively whereas it had no significant effect on peripheral oxygen saturation, respiratory rate, visual analog scale scores, and side effects. Dexmedetomidine infusion enhanced motor and sensory blockade quality and induced amnesia and sedation.

AB - Little is known about the perception of artificial spatial hearing by hearing impaired subjects. The purpose of this study was to investigate how listeners with hearing disorders perceived the effect of a spatialization feature designed for wireless microphone systems. Forty listeners took part in the experiments. They were arranged in four groups: normal-hearing, moderate, severe, and profound hearing loss. Their performance in terms of speech understanding and speaker localization was assessed with diotic and binaural stimuli. The results of the speech intelligibility experiment revealed that the subjects presenting a moderate or severe hearing impairment better understood speech with the spatialization feature. Thus, it was demonstrated that the conventional diotic binaural summation operated by current wireless systems can be transformed to reproduce the spatial cues required to localize the speaker, without any loss of intelligibility. The speaker localization experiment showed that a majority of the hearing-impaired listeners had similar performance with natural and artificial spatial hearing, contrary to the normal-hearing listeners. This suggests that certain subjects with hearing impairment preserve their localization abilities with approximated generic head-related transfer functions in the frontal horizontal plane.

AB - Objectives In order to facilitate the study of vocalizations in emerging genetic common marmoset models of neurodegenerative disorders, we aimed to analyze call type changes across age in a translational research environment. We hypothesized that acoustic parameters of vocalizations would change with age, reflecting growth of the vocal apparatus and a maturation of control needed to make adult like calls. Methods Nineteen developing common marmosets were longitudinally video- and audio-recorded between the ages of 1-149 days in a naturalistic setting without any vocalization elicitation protocol. Vocalizations were coded for call type (cry, tsik, trill, phee, and trill-phee) and analyzed for duration (sec), minimum and maximum frequency (Hz), and bandwidth (Hz). Mixed model linear regressions were performed to assess the effects of age on call parameters listed above for each call type. Results Cries decreased in duration (P = 0.038), maximum frequency (P = 0.047), and bandwidth (P = 0.023) with age. Tsik calls decreased in duration (P = 0.002) and increased in minimum frequency (P = 0.004) and maximum frequency (P = 0.005) with age. Trill calls increased in duration (P = 0.003), and trillphee bandwidth (P = 0.031) decreased with age. Discussion Our results demonstrate that development of common marmoset vocalizations is call type dependent and that changes in acoustic parameters can be detected without complex vocalization elicitation paradigms or specialized audio recording equipment. Thus, we demonstrate the feasibility of a naturalistic protocol to collect and objectively analyze marmoset vocalizations longitudinally. This approach may be useful for studying vocal communication deficits in genetic models of neurodegenerative disorders. PMID- 29457540 TI - Therapeutic efficacy of CD34+ cell-involved mononuclear cell therapy for no option critical limb ischemia: A meta-analysis of randomized controlled clinical trials. AB - Early-phase clinical trials in patients with critical limb ischemia (CLI) have shown positive results of mononuclear cell therapy. The current meta-analysis investigated whether cluster of differentiation (CD) 34+ mononuclear cell therapy (CD34+MCT) is effective for no-option CLI. Ten randomized controlled clinical studies of CD34+MCT for no-option CLI with 479 patients were identified and analyzed for pooled results. Compared to control groups, the CD34+MCT was associated with lower total amputation (odds ratio (OR): 0.45, p=0.01; 95% confidence interval (CI): 0.24-0.85) and a higher complete ulcer healing rate (OR: 2.80, p=0.008; 95% CI: 1.31-6.02), but showed no advantage in major amputation (OR: 0.58, p=0.11; 95% CI: 0.29-1.14) and all-cause mortality (OR: 0.82, p=0.62; 95% CI: 0.36-1.83) . Studies with a high CD34+ cell dosage showed significant results in major amputation (OR: 0.38, p=0.002; 95% CI: 0.21-0.70), total amputation (OR: 0.31, p=0.0002; 95% CI: 0.17-0.57) and complete ulcer healing (OR: 7.58, p=0.0005; 95% CI: 2.40-23.88), which were not observed in the low-dose studies. However, inclusion of placebo-controlled studies showed no improvement of the CD34+MCT in total amputation (OR: 0.67, p=0.42; 95% CI: 0.25 1.79), major amputation (OR: 1.31, p=0.43; 95% CI: 0.67-2.54) or complete ulcer healing (OR: 1.52, p=0.27; 95% CI: 0.72-3.21), which were extremely significant in non-placebo-controlled studies ( p<0.001). In conclusion, the significant results of CD34+MCT might not support its therapeutic benefit due to high placebo effect risk and considerable heterogeneity caused by distinct cell doses. More sizable double-blinded, randomized, placebo-controlled trials with higher CD34+ cell dosage are needed in the future. PMID- 29457541 TI - Can implicit measures detect source information in crime-related amnesia? AB - Participants who are asked to simulate amnesia for a mock crime have a weaker memory for this event when they have to give up their role as a feigner, than those who are not asked to feign memory loss. According to the source monitoring framework (SMF), this memory-undermining effect of simulating amnesia for a crime would be due to misattribution of the right source of information. However, we know that the content of self-generated information (e.g., feigned version of the crime) might be preserved and recognised over time as a result of elaborative cognitive processing. In the present study, we aimed to contrast these two explanations. We showed participants a mock crime video and we instructed them to either feign amnesia (simulators) or confess the mock crime (confessors). Next, a free recall memory test was administered. After one week, participants were asked to perform a personalised source monitoring task using the autobiographical Implicit Association Test (aIAT). As predicted, we found that simulators were able to discriminate the content of their self-generated feigned story of the crime from the original version. Moreover, simulators were quicker than confessors at the aIAT task. Practical and theoretical implications of our results are discussed. PMID- 29457542 TI - Exometabolomic Profiling of Bacterial Strains as Cultivated Using Arabidopsis Root Extract as the Sole Carbon Source. AB - The ability of microorganisms to use root-derived metabolites as growth substrates is a key trait for success in the rhizospheric niche. However, few studies describe which specific metabolites are consumed or to what degree microbial strains differ in their substrate consumption patterns. Here, we present a liquid chromatography-mass spectrometry (MS) exometabolomic study of three bacterial strains cultivated using either glucose or Arabidopsis thaliana root extract as the sole carbon source. Two of the strains were previously isolated from field-grown Arabidopsis roots, the other is Escherichia coli, included as a comparison. When cultivated on root extract, a set of 62 MS features were commonly taken up by all three strains, with m/z values matching components of central metabolism (including amino acids and purine or pyrimidine derivatives). Escherichia coli took up very few MS features outside this commonly consumed set, whereas the root-inhabiting strains took up a much larger number of MS features, many with m/z values matching plant-specific metabolites. These measurements define the metabolic niche that each strain potentially occupies in the rhizosphere. Furthermore, we document many MS features released by these strains that could play roles in cross-feeding, antibiosis, or signaling. We present our methodological approach as a foundation for future studies of rhizosphere exometabolomics. PMID- 29457543 TI - Greener chemicals for the future: QSAR modelling of the PBT index using ETA descriptors. AB - Persistent, bioaccumulative and toxic (PBT) chemicals symbolize a group of substances that are not easily degraded; instead, they accumulate in different organisms and exhibit an acute or chronic toxicity. The limited empirical data on PBT chemicals, the high cost of testing together with the regulatory constraints and the international push for reduced animal testing motivate a greater reliance on predictive computational methods like quantitative structure-activity relationship (QSAR) models in PBT assessment. Papa and Gramatica have recently proposed a PBT index that could be computed directly from structural features. In the current study, we have modelled the experimentally derived PBT index data using an extended topological atom (ETA) along with constitutional descriptors to show the usefulness of the ETA indices in modelling the endpoint. The models developed through a double cross-validation (DCV) method gave the best results in terms of both internal and external validation metrics. The developed models were comparable in predictive quality to those previously reported. The current models were further used for consensus predictions of PBT behaviour for a set of pharmaceuticals and a set of synthetic drug-like compounds. The developed models can be used in PBT hazard screening for identification and prioritization of chemicals from the structural information alone. PMID- 29457544 TI - Mesoscale organization of domains in the plasma membrane - beyond the lipid raft. AB - The plasma membrane is compartmentalized into several distinct regions or domains, which show a broad diversity in both size and lifetime. The segregation of lipids and membrane proteins is thought to be driven by the lipid composition itself, lipid-protein interactions and diffusional barriers. With regards to the lipid composition, the immiscibility of certain classes of lipids underlies the "lipid raft" concept of plasmalemmal compartmentalization. Historically, lipid rafts have been described as cholesterol and (glyco)sphingolipid-rich regions of the plasma membrane that exist as a liquid-ordered phase that are resistant to extraction with non-ionic detergents. Over the years the interest in lipid rafts grew as did the challenges with studying these nanodomains. The term lipid raft has fallen out of favor with many scientists and instead the terms "membrane raft" or "membrane nanodomain" are preferred as they connote the heterogeneity and dynamic nature of the lipid-protein assemblies. In this article, we will discuss the classical lipid raft hypothesis and its limitations. This review will also discuss alternative models of lipid-protein interactions, annular lipid shells, and larger membrane clusters. We will also discuss the mesoscale organization of plasmalemmal domains including visible structures such as clathrin-coated pits and caveolae. PMID- 29457550 TI - miR-505-3p controls chemokine receptor up-regulation in macrophages: role in familial hypercholesterolemia. AB - Familial hypercholesterolemia (FH) conveys a high risk of premature atherosclerosis as a result of lifelong exposure to high LDL cholesterol levels that are not fully reduced by standard-of-care lipid-lowering treatment. Inflammatory mediators have played a role in the progression of atherosclerotic lesions. Here, we investigated whether innate immunity cells in patients with FH have a specific proinflammatory phenotype that is distinct from that of cells in normal participants. To this end, miR-505-3p-a microRNA related to chronic inflammation-and its target genes were investigated in monocyte-derived macrophages (MACs) of patients with FH (FH-MACs) and non-FH controls (co-MACs). On the basis of the profiler PCR array analysis of agomiR-505-3p-transfected MACs, we identified the chemokine receptors, CCR3, CCR4, and CXCR1, as genes that are regulated by miR-505-3p via the transcription factor, RUNX1. miR-505-3p was significantly down-regulated, whereas CCR3, CCR4, CXCR, and RUNX1 were increased in FH-MAC compared with co-MAC, with the increase being more evident in the proinflammatory M1-like FH-MAC. Chemokine receptor levels were unrelated to LDL plasma levels at entry, but correlated with age in patients with FH, not in controls. In summary, we demonstrate for first time to our knowledge that MACs from FH-MACs have an inflammatory phenotype that is characterized by the up regulation of CCR3, CCR4, and CXCR1 under the control of miR-505-3p. These results suggest a chronic inflammatory condition in FH innate immunity cells that is not reverted by standard lipid-lowering treatment.-Escate, R., Mata, P., Cepeda, J.

PMID- 29457552 TI - Reciprocal regulation of YAP/TAZ by the Hippo pathway and the Small GTPase pathway. AB - Yes-associated protein 1 (YAP) and transcriptional co-activator with PDZ-binding motif (TAZ) (YAP/TAZ) are transcriptional coactivators that regulate genes involved in proliferation and transformation by interacting with DNA-binding transcription factors. Remarkably, YAP/TAZ are essential for cancer initiation or growth of most solid tumors. Their activation induces cancer stem cell attributes, proliferation, and metastasis. The oncogenic activity of YAP/TAZ is inhibited by the Hippo cascade, an evolutionarily conserved pathway that is governed by two kinases, mammalian Ste20-like kinases 1/2 (MST1/2) and Large tumor suppressor kinase 1/2 (LATS1/2), corresponding to Drosophila's Hippo (Hpo) and Warts (Wts), respectively. One of the most influential aspects of YAP/TAZ biology is that these factors are transducers of cell structural features, including polarity, shape, and cytoskeletal organization. In turn, these features are intimately related to the cell's ability to attach to other cells and to the surrounding extracellular matrix (ECM), and are also influenced by the cell's microenvironment. Thus, YAP/TAZ respond to changes that occur at the level of whole tissues. Notably, small GTPases act as master organizers of the actin cytoskeleton. Recent studies provided convincing genetic evidence that small GTPase signaling pathways activate YAP/TAZ, while the Hippo pathway inhibits them. Biochemical studies showed that small GTPases facilitate the YAP-Tea domain transcription factor (TEAD) interaction by inhibiting YAP phosphorylation in response to serum stimulation, while the Hippo pathway facilitates the YAP-RUNX3 interaction by increasing YAP phosphorylation. Therefore, small GTPase pathways activate YAP/TAZ by switching its DNA-binding transcription factors. In this review, we summarize the relationship between the Hippo pathway and small GTPase pathways in the regulation of YAP/TAZ. PMID- 29457553 TI - The difficulty of articulatory complexity. AB - In our commentary, we offer some support for the view that frequency rather than a language-independent definition of complexity is a main factor determining speech production in healthy adults. We further discuss the limits of defining articulatory complexity based on transcription data. If we want to gauge the impact of substantive constraints on speech production, context-specific production dynamics should be considered, as has been underscored by articulatory acoustic work on speech errors. PMID- 29457554 TI - Complexity of articulation planning in apraxia of speech: The limits of phoneme based approaches. AB - This report presents evidence suggesting that the phoneme-based approach taken by Romani, Galuzzi, Guariglia, and Goslin (Comparing phoneme frequency, age of acquisition, and loss in aphasia: Implications for phonological universals. Cognitive Neuropsychology, this issue) falls short of capturing the complexity of articulation planning in patients with apraxia of speech. Empirical and modelling data are reported to demonstrate that the apraxic pathomechanism resides in the hierarchical architecture of phonological words rather than in the context independent properties of phonemes. Because the factors determining complexity of articulation planning are interlaced between gestural, syllabic, and metrical levels, they cannot be captured by markedness rankings limited to any of these levels. PMID- 29457555 TI - Encoding of distributional regularities independent of markedness: Evidence from unimpaired speakers. AB - Romani, Galuzzi, Guariglia, and Goslin (Comparing phoneme frequency, age of acquisition and loss in aphasia: Implications for phonological universals. Cognitive Neuropsychology) used speech error data from individuals with acquired impairments to argue that independent from articulatory complexity, within language distributional regularities influence the processing of sound structure in speech production. Converging evidence from unimpaired speakers is reviewed, focusing on speech errors in language production. Future research should examine how articulatory and frequency factors are integrated in language processing. PMID- 29457556 TI - Is markedness a confused concept? AB - It is well known that, across languages, certain phonological features are more frequent than others. But whether these facts reflect abstract universal markedness constraints or functional pressures (auditory and articulatory difficulties and lexical frequency) is unknown. Romani, Galuzzi, Guariglia, and Goslin (2017) report that the putative markedness of phonological features captures their order of acquisition and their propensity to elicit errors in patients with an apraxia of speech (but not in phonological aphasia). The authors believe these results challenge the existence of abstract markedness constraints. They also raise some concerns about the explanatory utility of the markedness hypothesis. This commentary demonstrates that markedness is not inherently vague or vacuous nor is it falsified by Romani et al.'s empirical findings. As such, these results leave wide open the possibility that some phonological markedness constraints are abstract. PMID- 29457557 TI - Complexity in articulatory and segmental levels of production.

AB - Background As the population continues to age rapidly, clarifying the factors affecting the prognosis in very elderly stroke patients is essential to enhance the quality of their rehabilitation. Objectives To compare the functional recovery of elderly stroke patients classified into three age groups and to identify the predictors of functional recovery in the very elderly following acute inpatient rehabilitation. Methods Observational study: We collected data on 461 stroke patients in the neurology and neurosurgery ward and classified them into three age groups (65-74, 75-84, and >= 85 years). Functional recovery was compared among groups using the functional independence measure (FIM) at discharge and ADL recovery rate was compared using the Montebello rehabilitation factor score (MRFS). Multiple regression analysis was used to identify and compare the factors associated with functional recovery in each age group. Results Functional recovery in the >= 85 years group was lower than that in other age groups. Factors associated with activities of daily living (ADL) status (FIM at discharge) in the >= 85 years group were premorbid dependence (beta = -0.183, p = 0.011), motor paralysis (beta = -0.238, p = 0.001), and cognitive function (beta = 0.586, p < 0.001). Furthermore, the impact of cognitive function grew as age increased. Factors associated with ADL recovery rates (MRFS) in the >= 85 years group were non-paretic limb function (beta = -0.294, p = 0.004) and cognitive function (beta = 0.201, p = 0.047). Conclusions This study identified the factors associated with functional recovery among very elderly stroke patients. Effective forms of rehabilitation for very elderly stroke patients that take these factors into consideration need to be investigated. PMID- 29457560 TI - Prophylactic intra-aortic balloon counterpulsation before surgical myocardial revascularization in patients with acute myocardial infarction. AB - INTRODUCTION: Prophylactic intra-aortic balloon counterpulsation (pIABC) is recommended for high-risk patients undergoing coronary artery bypass grafting (CABG) surgery. Criteria for high-risk patients benefiting from pIABC are unclear. This study aimed to specifically describe the effect of pIABC on outcomes of patients with acute myocardial infarction (AMI) undergoing CABG. METHODS: In 178 of 484 AMI patients (non-ST-segment elevation myocardial infarction [NSTEMI] or ST-segment elevation myocardial infarction [STEMI] <=5 days before surgery) without cardiogenic shock who underwent CABG between 2008 and 2013, pIABC was initiated preoperatively. After propensity score matching, the outcomes of 400 patients were analyzed (pIABC: 150; Control: 250). RESULTS: After propensity score matching, baseline and operative characteristics were balanced between the groups except for a higher rate of patients with a left ventricular ejection fraction (LVEF)<=30% in the pIABC group (26% vs. Control: 13%; p=0.032). Seven point two percent (7.2%) of the control patients received an IABP intraoperatively or postoperatively. Postoperative extracorporeal life support (ECLS) was only needed in the control group (1.2% vs. 0%; p=0.01). Postoperative plasma curves of troponin I, creatine kinase (CK) and creatine kinase isoform MB (CK-MB) levels were reduced in the pIABC group compared with the control group. In-hospital mortality was reduced in the pIABC group (3.3% vs. control: 6.4%; p=0.18). After multivariate adjustment for other preoperative risk factors, pIABC was significantly protective concerning in-hospital mortality (HR 0.56; 95%-CI 0.023-0.74; p=0.021). Mortality (pIABC vs. control) was more affected in patients with preoperative LVEF<=30% (2/36 (5.6%) vs. 6/31 (19%); heart rate (HR) 0.25; 95%-CI 0.046-1.3; p=0.13) compared with LVEF>30% (3/114 (2.6%) vs. 10/219 (4.6%); HR 0.56; 95%-CI 0.15-2.1; p=0.55). Long-term survival did not differ between the groups. CONCLUSIONS: pIABC in CABG for AMI is associated with reduced perioperative cardiac injury and in-hospital mortality. Long-term survival is not affected. PMID- 29457561 TI - Psoriasis in the perspective of predictive, preventive participatory and personalized medicine. PMID- 29457562 TI - Quality of life outcomes in cochlear implantation of children with profound and multiple learning disability. AB - This study was performed to investigate the effect of cochlear implantation on the Quality of Life (QoL) of children with profound and multiple learning disability (PMLD). This cohort of children has been viewed historically as poor candidates for cochlear implantation as they generally have poor speech and hearing outcomes. The Irish National Cochlear Implant Program's prospectively maintained database was examined for all children implanted from July 1996 to July 2015. All charts of the 381 children implanted during this time were reviewed retrospectively; 16 children met criteria for being PMLD. For this cohort of patients, speech and hearing performance and the Glasgow Children's Benefit Inventory scores were retrospectively analyzed. Speech and hearing outcomes, as measured by Categories of Auditory Performance (CAP) and Speech Intelligibility Rating (SIR) scores, demonstrated little or no improvement from pre-implantation to an interval 3 years post-op; however, 11 out of 16 parents reported an improvement in their child's quality of life after implantation with 3 out of 16 reporting no improvement. This study suggests that despite children with PMLD performing poorly on traditional outcome measures such as CAP and SIR they may have improvement to their QoL after cochlear implantation. Further study is warranted to characterize the impact of CI on these children. PMID- 29457563 TI - Novel use of the Cochlear(r) Hybrid CI24REH cochlear implant. AB - Cochlear implantation is becoming more widespread. From its early days to date, huge strides have been made in the technology and surgical technique. However, one challenge remains: implanting malformed or abnormal cochleae. Even more challenging is a cochlea that appears normal at first glance, but is not. We present a case of a child with chondrodysplasia punctata, who had apparently morphologically normal inner ears, but with one major obstacle: the cochlea was smaller than normal in all dimensions. To the best of our knowledge, this is the first case described, and the solution is a novel one as well. PMID- 29457564 TI - Investigating Speech Recognition and listening effort with different device configurations in adult cochlear implant users. AB - OBJECTIVES: The purpose of this study was to investigate speech recognition in noise and listening effort among a group of adults with cochlear implants (CIs). Two main research questions were addressed. First, what are the effects of omni versus directional microphone configuration on speech recognition and listening effort for noisy conditions? Second, what is the effect of unilateral versus bimodal or bilateral CI listening on speech recognition and listening effort in noisy conditions? DESIGN: Sixteen adults (mean age 58 years) with CIs participated. Listening effort was measured using a dual-task paradigm and also using a self-reported rating of difficulty scale. In the dual-task measure, participants were asked to repeat monosyllabic words while at the same time press a button in response to a visual stimulus. Participants were tested in two baseline conditions (speech perception alone and visual task alone) and in the following experimental conditions: (1) quiet with an omnidirectional microphone, (2) noise with an omnidirectional microphone, (3) noise with a directional microphone, and (4) noise with a directional microphone and with a second sided CI or hearing aid. When present, the noise was fixed with a +5 dB signal-to-noise ratio. After each listening condition, the participants rated the degree of listening difficulty. RESULTS: Changing the microphone from omni to directional mode significantly enhanced speech recognition in noise performance. There were no significant changes in speech recognition between the unilateral and bimodal/bilateral CI listening conditions. Listening effort, as measured by reaction time, increased significantly between the baseline and omnidirectional quiet listening condition though did not change significantly across the remaining listening conditions. Self-perceived listening effort revealed a greater effort for the noisy conditions, and reduced effort with the move from an omni to a directional microphone. CONCLUSIONS: Directional microphones significantly improve speech in noise recognition over omnidirectional microphones and allowed for decreased self-perceived listening effort. The dual task used in this study failed to show any differences in listening effort across the experimental conditions and may not be sensitive enough to detect changes in listening effort.

AB - In 2011, the Committee on Nutrition of the European Society for Paediatric Gastroenterology, Hepatology and Nutrition systematically reviewed published evidence related to the safety and health effects of the administration of formulae supplemented with pro- and/or prebiotics compared with unsupplemented formulae. We updated evidence on the effects of the administration of prebiotic supplemented infant formulae (IF) compared with unsupplemented IF. Five databases were searched up to March 2017 for randomised controlled trials. In all, forty one publications were identified, including twenty-five new publications. The administration of currently evaluated prebiotic-supplemented formulae to healthy infants does not raise safety concerns with regard to growth and adverse effects. Some favourable clinical effects are possible, primarily stool softening, which may be beneficial in some infants. Currently, there is no existing robust evidence to recommend the routine use of prebiotic-supplemented formulae. The latter conclusion may reflect the small amount of data on specific prebiotics and outcomes, rather than a genuine lack of an effect.

AB - Gut maturation naturally accelerates at weaning in altricial mammalian species, such as the rat. Mimicking this, gut development can also be induced precociously, 3-4 d earlier than it would occur naturally, by enteral exposure to phytohaemagglutinin (PHA), or various proteases. We investigated the early effects of gut provocation on intestinal barrier and pancreatic functions, to get a better understanding of the mechanisms that initiate gut maturation. The effects of oral administration of protease (trypsin) or PHA to 14-d-old suckling rats were studied during 24 h in comparison with water-fed controls. Intestinal in vivo permeability was assessed by oral administration of different-sized marker molecules and measuring their passage into the blood or urine 3 h later. A period of 24 h following oral administration, both PHA and protease provocation stimulated small intestinal (SI) growth and pancreatic secretion, as indicated by decreased pancreatic trypsin and increased luminal enzyme content. Within 1 h of oral administration, both treatments prevented the absorption of macromolecules to blood that was observed in controls. PHA treatment hindered the passage of fluorescein isothiocyanate-dextran (FD) 4 to blood, whereas protease treatment temporarily increased plasma levels of FD4, and the urine lactulose:mannitol ratio, indicating increased intestinal leakiness. Following protease treatment, fluorescence microscopy showed decreased vesicular uptake of FD70 in the proximal SI and increased epithelial fluorescence in the distal SI. In conclusion, PHA and protease differed in their early effects on the intestinal barrier; both exerted a blocking effect on epithelial endocytosis, whereas protease treatment alone temporarily increased epithelial leakiness, which seemed to be confined to the distal SI.

AB - Several studies have found that, after repeated exposure to new words, children form orthographic representations that allow them to read those words faster and more fluently. However, these studies did not take into account variables related to the words. The aim of this study was to investigate the influence of sublexical variables on the formation of orthographic representations of words by Spanish children. The first experiment used pseudo-words of varying syllabic structure and syllabic frequency. The stimuli for the second experiment were formed with or without context-dependent graphemes. We found that formation of orthographic representations was influenced by syllabic structure (easier for words with simple syllabic structure) and the context-dependency of graphemes (easier in the absence of context-dependent graphemes), but not syllabic frequency. These results indicate that the easier it is to read a word, the easier it is to form an orthographic representation of it.

AB - Responsive parental communication during an infant's first year has been positively associated with later language outcomes. This study explores responsivity in mother-infant communication by modeling how change in guiding language between 7 and 11 months influences toddler vocabulary development. In a group of 32 mother-child dyads, change in early maternal guiding language positively predicted child language outcomes measured at 18 and 24 months. In contrast, a number of other linguistic variables - including total utterances and non-guiding language - did not correlate with toddler vocabulary development, suggesting a critical role of responsive change in infant-directed communication. We further assessed whether maternal affect during early communication influenced toddler vocabulary outcomes, finding that dominant affect during early mother infant communications correlated to lower child language outcomes. These findings provide evidence that responsive parenting should not only be assessed longitudinally, but unique contributions of language and affect should also be concurrently considered in future study. PMID- 29457575 TI - Testing the effect of an arbitrary subject pronoun on relative clause comprehension: a study with Hebrew-speaking children. AB - Previous studies have found that Hebrew-speaking children accurately comprehend object relatives (OR) with an embedded non-referential arbitrary subject pronoun (ASP). The facilitation of ORs with embedded pronouns is expected both from a discourse-pragmatics perspective and within a syntax-based locality approach. However, the specific effect of ASP might also be driven by a mismatch in grammatical features between the head noun and the pronoun, or by its relatively undemanding referential properties. We tested these possibilities by comparing ORs whose embedded subject is either ASP, a referential pronoun, or a lexical noun phrase. In all conditions, grammatical features were controlled. In a referent-identification task, the matching features made ORs with embedded pronouns difficult for five-year-olds. Accuracy was particularly low when the embedded pronoun was referential. These results indicate that embedded pronouns do not facilitate ORs across the board, and that the referential properties of pronouns affect OR processing.

Albumin, C-reactive protein (CRP) and haemoglobin (Hb) measured 2000-2010. We assessed daily mean levels of albumin, CRP and Hb from 30 days before to 30 days after bacteraemia and correlations between albumin vs. CRP and albumin vs. Hb. In linear regression models, we evaluated the contribution of CRP, Hb, chronic and acute variables to the albumin level variations. The mean albumin level (33.6 g/l) was steady before day 1, declined to 29.3 g/l on day 1 with little increase afterward. The mean CRP increased from day -5, peaked on day 1 and declined thereafter. The mean Hb level was fairly constant during days -30/30. Albumin was inversely (R range, - 0.18/-0.47, P < 10-4) correlated with the CRP level and positively (R = 0.17-0.46, P < 10-4) correlated with the HB level. In most models, CRP was the first variable that contributed to the albumin variations, 34 70% of the full model. The sudden decrease of albumin levels, without sudden fluctuations of CRP or Hb, indicated that hypoalbuminaemia was a marker of trans capillary leakage. PMID- 29457577 TI - Space, place and (waiting) time: reflections on health policy and politics. AB - Health systems have repeatedly addressed concerns about efficiency and equity by employing trans-national comparisons to draw out the strengths and weaknesses of specific policy initiatives. This paper demonstrates the potential for explicit historical analysis of waiting times for hospital treatment to add value to spatial comparative methodologies. Waiting times and the size of the lists of waiting patients have become key operational indicators. In the United Kingdom, as National Health Service (NHS) financial pressures intensified from the 1970s, waiting times have become a topic for regular public and political debate. Various explanations for waiting times include the following: hospital consultants manipulate NHS waiting lists to maintain their private practice; there is under-investment in the NHS; and available (and adequate) resources are being used inefficiently. Other countries have also experienced ongoing tensions between the public and private delivery of universal health care in which national and trans-national comparisons of waiting times have been regularly used. The paper discusses the development of key UK policies, and provides a limited Canadian comparative perspective, to explore wider issues, including whether 'waiting crises' were consciously used by policymakers, especially those brought into government to implement new economic and managerial strategies, to diminish the autonomy and authority of the medical professional in the hospital environment.

AB - OBJECTIVE: Physical activity (PA) levels and dietary habits are considered some of the most important factors associated with obesity. The present study aimed to examine the association between PA level and food and beverage consumption in European children (2-10 years old).Design/Setting/SubjectsA sample of 7229 children (49.0 % girls) from eight European countries participating in the IDEFICS (Identification and prevention of Dietary and lifestyle induced health EFfects In Children and infantS) study was included. Moderate-to-vigorous PA (MVPA) was assessed objectively with accelerometers. FFQ was used to register dietary habits. ANCOVA and binary logistic regression were applied. RESULTS: Boys who spent less time in MVPA reported lower consumption of vegetables, fruits, cereals, yoghurt, milk, bread, pasta, candies and sugar-sweetened beverages (SSB) than boys who spent more time in MVPA (P<0.05). Moreover, boys who spent less time in MVPA were more likely to consume fast foods and water than those in the highest MVPA tertile (P<0.05). Girls who spent less time in MVPA reported lower consumption frequencies of vegetables, pasta, bread, yoghurt, candies, jam/honey and SSB than girls in the highest MVPA tertile (P<0.05). Also, girls in the lowest MVPA tertile were more likely to consume fast foods and water than those with high levels of MVPA (P<0.05). CONCLUSIONS: Food intake among European children varied with different levels of daily MVPA. Low time spent in MVPA was associated with lowest consumption of both high- and low-energy-dense foods and high fast-food consumption. PMID- 29457581 TI - Association between TLR2 + 2477G/A polymorphism and bacterial meningitis: a meta analysis. AB - Toll-like receptor 2 (TLR2) is a key member of TLRs, which is crucial in the initial inflammatory response against bacteria. TLR2, is also the initial barrier against bacterial infection and plays an important role in recognising a variety of bacterial lipoproteins. Several studies have been performed to investigate the TLR2 + 2477G/A polymorphism and bacterial meningitis susceptibility. Unfortunately, the results of previous studies were controversial. Therefore, we performed a meta-analysis to derive a more precise estimation of the association. The association between the TLR2 + 2477G/A polymorphism and bacterial meningitis susceptibility was assessed by odds ratios together with their 95% confidence intervals (CI). Six studies were enrolled in the present meta-analysis. Overall, no significant association between TLR2 + 2477G/A polymorphism and bacterial meningitis risk were found under allele contrast (A vs. G: OR = 1.15, 95% CI = 0.93-1.43, P = 0.202), recessive genetic model (AA vs. AG/GG: OR = 1.12, 95% CI = 0.90-1.41, P = 0.313). The significant association was found between TLR2 + 2477G/A polymorphism and pneumococcal meningitis risk under allele contrast (A vs. G: OR = 1.54, 95% CI = 1.01-2.36, P = 0.046), recessive genetic model (AA vs. AG/GG: OR = 1.63, 95% CI = 1.03-2.57, P = 0.035). We conclude that TLR2 + 2477G/A polymorphism is not associated with meningococcal meningitis risk but contributes an increased risk of pneumococcal meningitis.

AB - Several previous prospective studies suggest that consumption of green leafy and cruciferous vegetables may lower the risk of type 2 diabetes (T2D). We investigated the association between consumption of different types of vegetables in relation to T2D risk in an Asian Population. We included 45 411 participants (age range: 45-74 years) of the Singapore Chinese Health Study (SCHS) free of diabetes, cancer or CVD at baseline (1993-1998). Dietary information was collected using a validated FFQ. Physician-diagnosed incident diabetes was reported at follow-up I (1999-2004) and II (2006-2010) interviews. Cox proportional hazards regression was used to estimate hazard ratio (HR) and 95 % CI of T2D risk. An updated meta-analysis was also conducted to summarise results for green leafy and cruciferous vegetables. During 494 741 person-years of follow up, 5207 incident T2D occurred. After adjustment for potential confounders, neither total vegetables (top v. bottom quintile HR=1.08; 95 % CI 0.98, 1.18, P trend=0.66) nor specific vegetables including dark green leafy vegetables (HR=1.05; 95 % CI 0.96, 1.15, P trend=0.21) and cruciferous vegetables (HR=0.97; 95 % CI 0.88, 1.06, P trend=0.29) were substantially associated with risk of T2D. A meta-analysis (eleven studies with 754 729 participants and 58 297 cases) including the SCHS and all previous prospective studies suggested borderline significant inverse associations between green leafy (summary relative risk (RR)=0.91; 95 % CI 0.84, 1.00) and cruciferous vegetable consumption (RR=0.87; 95 % CI 0.76, 1.00) and T2D risk, with moderate-to-high heterogeneity. In conclusion, green leafy or cruciferous vegetable consumption was not substantially associated with risk of T2D in an Asian population. Meta-analysis of available cohort data indicated that evidence for a beneficial effect of green leafy or cruciferous vegetable consumption on T2D risk is not convincing. PMID- 29457583 TI - Financial Incentives to Reduce Hospital-Acquired Infections Under Alternative Payment Arrangements. AB - OBJECTIVEThe financial incentives for hospitals to improve care may be weaker if higher insurer payments for adverse conditions offset a portion of hospital costs. The purpose of this study was to simulate incentives for reducing hospital acquired infections under various payment configurations by Medicare, Medicaid, and private payers.DESIGNMatched case-control study.SETTINGA large, urban hospital system with 1 community hospital and 2 tertiary-care hospitals.PATIENTSAll patients discharged in 2013 and 2014.METHODSUsing electronic hospital records, we identified hospital-acquired bloodstream infections (BSIs) and urinary tract infections (UTIs) with a validated algorithm. We assessed excess hospital costs, length of stay, and payments due to infection, and we compared them to those of uninfected patients matched by propensity for infection.RESULTSIn most scenarios, hospitals recovered only a portion of excess HAI costs through increased payments. Patients with UTIs incurred incremental costs of $6,238 (P<.01), while payments increased $1,901 (P<.05) at public diagnosis-related group (DRG) rates. For BSIs, incremental costs were $15,367 (P<.01), while payments increased $7,895 (P<.01). If private payers reimbursed a 200% markup over Medicare DRG rates, hospitals recovered 55% of costs from BSI and UTI among private-pay patients and 54% for BSI and 33% for UTI, respectively, across all patients. Under per-diem payment for private patients with no markup, hospitals recovered 71% of excess costs of BSI and 88% for UTI. At 150% markup and per-diem payments, hospitals profited.CONCLUSIONSHospital incentives for investing in patient safety vary by payer and payment configuration. Higher payments provide resources to improve patient safety, but current payment structures may also reduce the willingness of hospitals to invest in patient safety.Infect Control Hosp Epidemiol 2018;39:509-515. PMID- 29457584 TI - Immunological Stability of Clostridium difficile Toxins in Clinical Specimens. AB - OBJECTIVE The impact of storage on stability and detection of Clostridium difficile toxins in feces is poorly understood. The objective of this study was to investigate the immunological stability of C. difficile toxins in clinical stool specimens under different storage conditions by evaluating this stability using toxin detection by enzyme immunoassay (EIA). METHODS Stool specimens positive for C. difficile infection (CDI) by quantitative polymerase chain reaction (qPCR) were used for EIA testing with the C. difficile Tox A/B II kit. The EIA-positive specimens were stored aerobically under refrigerated (4-10 degrees C) and frozen (-30 degrees C and -80 degrees C) conditions. Measurement of toxin quantity was conducting using optical density (OD) on days 0, 14, 30, 60, 90, and 120 of storage. RESULTS Clostridium difficile toxins demonstrated good detection in undiluted stool specimens by EIA up to 120 days of storage. Good detection of the toxins was observed in diluted samples at refrigerated and 80 degrees C temperatures. Dilution detrimentally affected toxin detection at -30 degrees C. CONCLUSION Storage of undiluted clinical stool specimens at refrigerated, -30 degrees C, and -80 degrees C temperatures for up to 120 days has no discernible effect on the immunological stability of C. difficile cytotoxins. However, storage at -30 degrees C has a detrimental effect on C. difficile toxin stability in diluted specimens. Infect Control Hosp Epidemiol 2018;39:434-438. PMID- 29457585 TI - Training nurses in a competency framework to support adults with epilepsy and intellectual disability: the EpAID cluster RCT. AB - BACKGROUND: People with an intellectual (learning) disability (ID) and epilepsy have an increased seizure frequency, higher frequencies of multiple antiepileptic drug (AED) use and side effects, higher treatment costs, higher mortality rates and more behavioural problems than the rest of the population with epilepsy. The introduction of nurse-led care may lead to improvements in outcome for those with an ID and epilepsy; however, this has not been tested in a definitive clinical trial. OBJECTIVE: To determine whether or not ID nurses, using a competency framework developed to optimise nurse management of epilepsy in people with an ID, can cost-effectively improve clinical and quality-of-life outcomes in the management of epilepsy compared with treatment as usual. DESIGN: Cluster randomised two-arm trial. SETTING: Community-based secondary care delivered by members of community ID teams. PARTICIPANTS: Participants were adults aged 18-65 years with an ID and epilepsy under the care of a community ID team and had had at least one seizure in the 6 months before the trial. INTERVENTIONS: The experimental intervention was the Learning Disability Epilepsy Specialist Nurse Competency Framework. This provides guidelines describing a structure and goals to support the delivery of epilepsy care and management by ID-trained nurses. MAIN OUTCOME MEASURES: The primary outcome was the seizure severity scale from the Epilepsy and Learning Disabilities Quality of Life questionnaire. Measures of mood, behaviour, AED side effects and carer strain were also collected. A cost utility analysis was undertaken along with a qualitative examination of carers' views of participants' epilepsy management. RESULTS: In total, 312 individuals were recruited into the study from 17 research clusters. Using an intention-to treat analysis controlling for baseline individual-level and cluster-level variables there was no significant difference in seizure severity score between the two arms. Altogether, 238 complete cases were included in the non-imputed primary analysis. Analyses of the secondary outcomes revealed no significant differences between arms. A planned subgroup analysis identified a significant interaction between treatment arm and level of ID. There was a suggestion in those with mild to moderate ID that the competency framework may be associated with a small reduction in concerns over seizure severity (standard error 2.005, 95% confidence interval -0.554 to 7.307; p = 0.092). However, neither subgroup showed a significant intervention effect individually. Family members' perceptions of nurses' management depended on the professional status of the nurses, regardless of trial arm. Economic analysis suggested that the competency framework intervention was likely to be cost-effective, primarily because of a reduction in the costs of supporting participants compared with treatment as usual. LIMITATIONS: The intervention could not be delivered blinded. Treatment as usual varied widely between the research sites. CONCLUSIONS: Overall, for adults with an ID and epilepsy, the framework conferred no clinical benefit compared with usual treatment. The economic analysis suggested that there may be a role for the framework in enhancing the cost-effectiveness of support for people with epilepsy and an ID. Future research could explore the specific value of the competency framework for those with a mild to moderate ID and the potential for greater long-term benefits arising from the continuing professional development element of the framework.

AB - Group-VIIB transition metal dichalcogenides (TMDCs) are known to be stabilized solely in a distorted 1T phase termed as 1T" phase, which is compared to many stable or metastable phases in other TMDCs. Using first-principles calculations, we study the structural origin of 1T" phase group-VIIB TMDCs. We find that quasi 1D Peierls-like instability is responsible for the transition to the 1T" phase ReS2 monolayer from the 1T' phase, another distorted 1T phase. Two half-filled bands in 1T'-ReS2 make sharp peaks in the Lindhard function that prompt the charge density wave (CDW) phase with large band gap opening. Our calculations show that overlapping of the two bands in a broad energy range leads to robust CDW phase or stable 1T" phase in group-VIIB TMDCs against compositional variation, which is in stark contrast to typical Peierls instability driven by a single band. Calculated total energy curve near the critical point exhibits the feature of the first-order Landau transition due to local chemical bonding. The structural stability of the 1T" phase in group-VIIB TMDCs is thus guaranteed by two half-filled bands and local chemical bonding. PMID- 29457587 TI - Power cavitation-guided blood-brain barrier opening with focused ultrasound and microbubbles. AB - Image-guided monitoring of microbubble-based focused ultrasound (FUS) therapies relies on the accurate localization of FUS-stimulated microbubble activity (i.e. acoustic cavitation). Passive cavitation imaging with ultrasound arrays can achieve this, but with insufficient spatial resolution. In this study, we address this limitation and perform high-resolution monitoring of acoustic cavitation mediated blood-brain barrier (BBB) opening with a new technique called power cavitation imaging. By synchronizing the FUS transmit and passive receive acquisition, high-resolution passive cavitation imaging was achieved by using delay and sum beamforming with absolute time delays. Since the axial image resolution is now dependent on the duration of the received acoustic cavitation emission, short pulses of FUS were used to limit its duration. Image sets were acquired at high-frame rates for calculation of power cavitation images analogous to power Doppler imaging. Power cavitation imaging displays the mean intensity of acoustic cavitation over time and was correlated with areas of acoustic cavitation-induced BBB opening. Power cavitation-guided BBB opening with FUS could constitute a standalone system that may not require MRI guidance during the procedure. The same technique can be used for other acoustic cavitation-based FUS therapies, for both safety and guidance.

AB - In the present work, we report on the use of organized TiO2 nanotube (NT) layers with a regular intertube spacing for the growth of highly defined alpha-Fe2O3 nano-needles in the interspace. These alpha-Fe2O3 decorated TiO2 NTs are then explored for Li-ion battery applications and compared to classic close-packed (CP) NTs that are decorated with various amounts of nanoscale alpha-Fe2O3. We show that NTs with tube-to-tube spacing allow uniform decoration of individual NTs with regular arrangements of hematite nano-needles. The tube spacing also facilitates the electrolyte penetration as well as yielding better ion diffusion. While bare CP NTs show a higher capacitance of 71 MUAh cm-2 compared to bare spaced NTs with a capacitance of 54 MUAh cm-2, the hierarchical decoration with secondary metal oxide, alpha-Fe2O3, remarkably enhances the Li-ion battery performance. Namely, spaced NTs with alpha-Fe2O3 decoration have an areal capacitance of 477 MUAh cm-2, i.e. they have nearly ~8 times higher capacitance. However, the areal capacitance of CP NTs with alpha-Fe2O3 decoration saturates at 208 MUAh cm-2, i.e. is limited to ~3 times increase.

AB - OBJECTIVE: To observe the short-term efficacy of Pipeline embolization divice (PED) for the treatment of complex intracranial aneurysms. METHODS: The clinical data of 29 consecutive patients with 32 intracranial aneurysms treated with PED between April 2015 to September 2016 were analyzed retrospectively. There were 3 small aneurysm, 15 large aneurysms, 8 giant aneurysms, 5 fusiform ayneurysms and 1 recidivation. The vessels include 25 anterior circulation and 4 posterior circulation. RESULTS: We treated 31 aneurysms with 30 PEDs and all of the stents were implanted successfully. 1 case of single aneurysm was multiple divices implanted and 1 case of 3 aneurysms were treated by single PED. 12 of the 29 patients were implanted PED only, 17 were implanted PED with coils, 2 underwent balloon remodeling after the PED implanted. The ostia of 19 ophthalmic arteries, 10 posterior communicating arteries, 4 posterior inferior cerebellar arteries and 1 anterior cerebral artery were covered by PED during procedures; 1 ophthalmic arteries and 1 posterior communicating artery disappeared, no branch vessels occlusion and parent artery stenosis occurred.Hemorrhagic complacations occurred in 2 patients, 2 hours and 5 days after procedure respectively. Radiographic follow-up examnations were carried out in 24 patients and revealed complete occlusion in 21 patients, uncomplete occlusion in 3 patients. No neurological injure occurred in 27 patients who received a clinical follow-up. CONCLUSION: PED provide a safe and effective methord for the treatment of intracranial complex aneurysms like wide-neck aneurysms, fusiform aneurysms, giant aneurysms in low risk of procedural complications and high rates of aneurysm occlusion.

AB - OBJECTIVE: Understanding the biomechanical properties of hernia meshes is essential in facilitating their selection. The aim of this study was to evaluate the mechanical compatibility of hernia meshes and human abdominal fascia and assess their applicability in hernia repair. METHODS: Uniaxial tensile tests were performed. A total of eight hernia meshes were tested - three standard meshes (Surgimesh(r), SurgiproTM, TecnoMesh(r)) and five light-weight meshes (Optilene(r), TiO2MeshTM, ParietexTM, VyproTM II, UltraproTM). RESULTS: The secant modulus at 5% strain and the level of orthotropy (the ratio between tensile stress in the longitudinal and the transversal direction) at 5% strain were calculated from the stress-stretch ratio curves. The impact of pore size and thickness on the elastic properties of these meshes was determined. The relationships between density and elasticity as well as between elasticity and the strain developed at 16 N/cm load were presented. The resulting mechanical properties of meshes were compared to the elasticity, orthotropy and deformability of human abdominal fascia. CONCLUSIONS: VyproTM II and ParietexTM brands display properties similar to those of fascia in both directions. The TiO2MeshTM and UltraproTM display deformability close to the deformability at 16 N/cm of the fascia transversalis. Only the VyproTM II brand's orthotropy is similar to that of fascia.

AB - BACKGROUND: Polycaprolactone (PCL)-biphasic calcium phosphate (BCP) scaffolds fabricated using Melt-Stretching and Compression Molding (MSCM) can release calcium and phosphate ions, which are essential for bone formation. OBJECTIVE: Responses of the osteoblasts seeded on three groups of scaffolds including group A; PCL-20% BCP (%wt), group B; PCL-30% BCP and group C (control); pure PCL (100% PCL) were evaluated. METHODS: The cell-scaffold constructs were made by seeding osteoblast cell lines at 1*105 cells/scaffold. The constructs of each group were divided for culturing in proliferation medium (PR) and osteogenic induction medium (OS) for 30 days. RESULTS: The cells attached and grew on the scaffolds of all groups. The cell number and the differentiation markers of groups A and B were remarkably higher than those of group C over the observation periods. Slow proliferation of the cells of group A and B in the PR medium in the first 7 days corresponded to the maximum increases in alkaline phosphatase activities (ALP). The maximum levels of ALP of those groups in the OS medium were not detected until day 14. The levels of osteocalcin of those groups were not statistically different when cultured in both mediums. CONCLUSIONS: The MSCM scaffolds are suitable for supporting attachment and growth of the osteoblasts. Additional BCP into the PCL-based scaffolds accelerate early differentiation of the cells in the constructs even without osteogenic-inductive condition.

AB - This paper describes the development of mitoxantrone-loaded PEGylated graphene oxide/magnetite nanoparticles (PEG-GO/Fe3O4-MTX), and investigation of its preliminary drug delivery performance. For this, the GO was synthesized through oxidizing graphite powder, and subsequently carboxylated using a substitution nucleophilic reaction. The carboxylated GO (GO-COOH) was then conjugated with amine end-caped PEG chains by Steglich esterification. Afterward, GO-PEG/Fe3O4 nanocomposite was synthesized through the anchoring of Fe3O4 nanoparticles onto the surface of GO-PEG during the sonication. The biocompatibility and MTX-loading capacity of the synthesized GO-PEG/Fe3O4 nanocomposite were evaluated. The pH dependent drug release behavior and cytotoxicity effect of the MTX-loaded GO PEG/Fe3O4 nanocomposite were also studied. According to biocompatibility, pH dependent drug release behavior as well as superior physicochemical and biological characteristics of graphene and magnetite nanoparticles, it is expected that the GO-PEG/Fe3O4 nanocomposite may be applied as de novo drug delivery system (DDS) for cancer therapy using both chemo- and photothermal therapy approaches.

AB - The aim of this study is to produce the smart hydrogel to use insulin release for human body. p(HEMA-co-Eudragit L-100) hydrogels containing different ratios of 2 Hydroxyethyl methacrylate (HEMA) and Eudragait L-100 were synthesized by using ammonium persulfate (APS) as an initiator and ethylene glycol dimethacrylate (EGDMA) as a cross linker. The structures of hydrogels produced were characterized by using Fourier Transform Infrared Spectroscopy (FT-IR) and Scanning electron microscope (SEM) analysis. In this way, optimum synthesis conditions were determined for p(HEMA-co-Eudragit L-100) hydrogels by using Taguchi method as an optimization method. The gelling percentages of all hydrogels were calculated. After all, the swelling behaviors (%) of hydrogels were investigated in range of various times (1-44 hrs), temperatures (20-50 degrees C) and pH (2-12) and the optimum process conditions in the production of hydrogels were determined. Consequently, the optimum time, temperature and pH were 24 hours, 37 degrees C and 7, respectively. Thus, this hydrogel could be evaluated in insulin release for diabetes treatment and drug industry.

AB - BACKGROUND: Recently, polyethylene glycol (PEG) modified gold nanoparticles have been studied to maintaining long-term stability in biological fluids. Its biodistribution was also reported, however, comparison of bare gold nanoparticles and PEGylated gold nanoparticles with equal particle size is not sufficient. OBJECTIVE: We prepared bare gold nanoparticles and PEGylated gold nanoparticles with diameters of 20-30-nm or 50-nm to avoid the influence of particle diameter, and studied their biodistribution in the mouse. METHODS: Gold concentrations in brain, heart, lungs, liver, stomach, pancreas, spleen, kidneys, blood, urine, and feces were measured at 0.5, 1, 2, 3, 6, 12, 18, 24, and 48 h after administration of gold nanoparticles using inductively coupled plasma atomic emission spectrometry. RESULTS: At 48 h after intravenous administration, accumulation in the liver and spleen was significantly reduced by PEGylation, and the gold amounts of PEGylated gold nanoparticles with diameters of 20-30 nm and 50-nm in the brain were 3.6 times and 2.7 times higher than those of bare gold nanoparticles, respectively. CONCLUSIONS: These results indicated that the usefulness of PEGylated gold nanoparticles with small particle size for a drug carrier. PMID- 29457595 TI - Minoxidil-encapsulated poly(L-lactide-co-glycolide) nanoparticles with hair follicle delivery properties prepared using W/O/W solvent evaporation and sonication. AB - BACKGROUND: Nanoparticles with a diameter of 100-150 nm prepared using poly(lactide-co-glycolide) can be delivered to hair follicles. Moreover, it was shown that drug release from nanoparticles was prolonged by using poly(L-lactide co-glycolide) (PLLGA). OBJECTIVE: The aim of this study was to prepared minoxidil encapsulated PLLGA nanoparticles and accumulate minoxidil in hair follicles utilizing its drug delivery properties for effective treatment of male and female androgenetic alopecia. METHODS: Minoxidil-encapsulated PLLGA nanoparticles were prepared using W/O/W solvent evaporation and sonication, and the ability of PLLGA nanoparticles to deliver to hair follicles was evaluated by in vivo transdermal delivery study using C3H/He mice and tape stripping and cyanoacrylate skin surface biopsy. RESULTS: Eight hours after administration of samples, minoxidil encapsulated PLLGA nanoparticles delivered 3.1 times more minoxidil in stratum corneum and 2.5 times more in hair follicles r compared to minoxidil aqueous solution. In addition, we found that 4.8% of the dose of minoxidil-encapsulated PLLGA nanoparticles were delivered to the hair follicles. CONCLUSIONS: In this study, it was shown that nanoparticulation using PLLGA7510 suppressed minoxidil release from nanoparticles and improved drug delivery amount to hair follicles.

AB - BACKGROUND: Alveolar cleft repair is an important step in the sequence of treatments for cleft lip and palate. Intrinsically osteoinductive materials have been the subject of research interest. OBJECTIVE: The aim of this study was to explore the use of osteoinductive biphasic calcium phosphate (BCP) ceramics to repair alveolar cleft defects in dogs. METHODS: We prepared two kinds of BCP ceramic with different physical characteristics: osteoinductive BCP (OBCP) and non-osteoinductive BCP (NBCP). Bilateral alveolar cleft models were surgically established in dogs. On one side, OBCP was implanted in the defect; on the opposite side NBCP was implanted as a control. The materials were also implanted in the femoral muscles to test their properties at non-osseous sites. The osteogenic ability of materials was evaluated with imaging, spiral CT, histology and fluorescent dye tests. RESULTS: At the muscular implantation sites, new bone formed in all of the OBCP samples, but none in the NBCP samples. Imaging and spiral CT revealed good appearance and continuity of the alveolar cleft postoeration, with normal eruption of the bilateral permanent teeth in the groups. Histological and fluorescent dye testing revealed new bone formation in both groups in situ. However, earlier osteogenesis initiation and bone remodeling were superior with OBCP. Osteogenic process in the intramuscular samples with OBCP was similar to that seen in situ. CONCLUSIONS: Our findings indicated that osteoinductive biphasic calcium phosphate ceramics (OBCP) have superior characteristics in alveolar cleft repair compared with non-osteoinductive calcium phosphate ceramics (NBCP). PMID- 29457597 TI - Injectable collagen/RGD systems for bone tissue engineering applications. AB - Imbalance crosslink density and polymer concentration gradient is formed within the traditional alginate hydrogel using calcium chloride as a crosslinking agent in external gelation for instantaneously process. In this studying, type I collagen (Col I) blended calcium salt form of poly(gamma-glutamic acid) (gammaCaPGA) was mixing with RGD-modified alginate with convenient gelation process and suitable for practical use. The hydrophilicity of the resulting hydrogels was evaluated through swelling tests, water retention capacity tests, and water vapor permeation tests. Mineralization was qualitatively evaluated by alizarin red dyeing at day 14, verifying the deposition of calcium. The in vitro osteogenic differentiation is monitored by determining the early and late osteocalcin (OCN) and osteopontin (OPN) markers with MG63 cells. Obtained results demonstrated that no extremely changes in mechanical properties. After 14 days of culture, hydrogels significantly stimulated OCN/OPN gene expressions and MG63 cell proliferation. Unusually, gammaCaPGA with RGD-modified alginate appeared better calcium deposition in 14 days than the other. However, addition of Col I can counterpoise RGD effect in blood coagulation and platelet adhesion made the hydrogel more flexibility and selectively in use. This studying provided that non covalently crosslinked hydrogel by gammaCaPGA with alginate can be upgrading by RGD and Col I in water uptake capability, obviously effective for MG63 cells and are remarkably biocompatible and exhibited no cytotoxicity. Moreover, results also displayed the injectable process without complicated procedure, have high cost/performance ratio and have great potential for bone regeneration. PMID- 29457598 TI - In vivo biocompatibility and degradation of novel Polycaprolactone-Biphasic Calcium phosphate scaffolds used as a bone substitute. AB - BACKGROUND: Biocompatibility and degradation of poly epsilon-caprolactone (PCL) Biphasic Calcium Phosphate (BCP) scaffolds fabricated by the "Melt Stretching and Compression Molding (MSCM)" technique were evaluated in rat models. OBJECTIVES: Degradation behaviors and histological biocompatibility of the PCL-20% BCP MSCM scaffolds and compare with those of PCL-20% beta-tricalcium phosphate (TCP) scaffolds commercially fabricated by Fused Deposition Modeling (FDM) were evaluated. METHODS: The study groups included Group A: PCL-20% BCP MSCM scaffolds and Group B: PCL-20% TCP FDM scaffolds, which were implanted subcutaneously in twelve male Wistar rats. On day 14, 30, 60 and 90, dimensional changes of the scaffolds and their surrounding histological features were assessed using Micro Computed Tomography (MU-CT) and histological analysis. Changes of their molecular weight were assessed using Gel Permeation Chromatography (GPC). RESULTS: Formation of collagen and new blood vessels throughout the scaffolds of both groups increased with time with low degrees of inflammation. The MU-CT and GPC analysis demonstrated that the scaffolds of both groups degraded with time, but, their molecular weight slightly changed over the observation periods. All results of both groups were not significantly different. CONCLUSIONS: The PCL-20% BCP MSCM scaffolds were biocompatible and biodegradable in vivo. Their properties were comparable to those of the commercial PCL-20% TCP scaffolds. PMID- 29457599 TI - Conclusions about testosterone therapy and cardiovascular risk. PMID- 29457600 TI - Public online information about tinnitus: A cross-sectional study of YouTube videos. AB - Purpose: To examine the information about tinnitus contained in different video sources on YouTube. Materials and Methods: The 100 most widely viewed tinnitus videos were manually coded. Firstly, we identified the sources of upload: consumer, professional, television-based clip, and internet-based clip. Secondly, the videos were analyzed to ascertain what pertinent information they contained from a current National Institute on Deafness and Other Communication Disorders fact sheet. Results: Of the videos, 42 were consumer-generated, 33 from media, and 25 from professionals. Collectively, the 100 videos were viewed almost 9 million times. The odds of mentioning "objective tinnitus" in professional videos were 9.58 times those from media sources [odds ratio (OR) = 9.58; 95% confidence interval (CI): 1.94, 47.42; P = 0.01], whereas these odds in consumer videos were 51% of media-generated videos (OR = 0.51; 95% CI: 0.20, 1.29; P = 0.16). The odds that the purpose of a video was to sell a product or service were nearly the same for both consumer and professional videos. Consumer videos were found to be 4.33 times as likely to carry a theme about an individual's own experience with tinnitus (OR = 4.33; 95% CI: 1.62, 11.63; P = 0.004) as media videos. Conclusions: Of the top 100 viewed videos on tinnitus, most were uploaded by consumers, sharing individuals' experiences. Actions are needed to make scientific medical information more prominently available and accessible on YouTube and other social media. PMID- 29457601 TI - Influences of combined traffic noise on the ability of learning and memory in mice. AB - Objective: The present study aimed to evaluate the influences of combined traffic noise (CTN) on the ability of learning and memory in mice. Materials and Methods: The Institute of Cancer Research (ICR) mice were exposed to CTN from highways and high-speed railways for 42 days, whose day-night equivalent continuous A-weighted sound pressure level (Ldn) was 70 dB(A). On the basis of behavioral reactions in Morris water maze (MWM) and the concentrations of amino acid neurotransmitters in the hippocampus, the impacts of CTN on learning and memory in mice were examined. Results: The MWM test showed that the ability of learning and memory in mice was improved after short-term exposure (6-10 days, the first batch) to 70 dB(A) CTN, which showed the excitatory effect of stimuli. Long-term exposure (26-30 days, the third batch; 36-40 days, the fourth batch) led to the decline of learning and memory ability, which indicated the inhibitory effect of stimuli. Assays testing amino acid neurotransmitters showed that the glutamate level of the experimental group was higher than that of the control group in the first batch. However, the former was lower than the latter in the third and fourth batches. Both, behavioral reactions and the concentrations of amino acid neurotransmitters, testified that short-term exposure and long-term exposure resulted in excitatory effect and inhibitory effect on the ability of learning and memory, respectively. Conclusion: The effects of 70 dB(A) CTN on the ability of learning and memory were closely related to the exposure duration. Furthermore, those effects were regulated and controlled by the level of glutamate in the hippocampus. PMID- 29457602 TI - Examination of previously published data to identify patterns in the social representation of "Loud music" in young adults across countries. AB - Purpose: The current study was aimed at understanding the patterns in the social representation of loud music reported by young adults in different countries. Materials and Methods: The study included a sample of 534 young adults (18-25 years) from India, Iran, Portugal, United Kingdom, and United States. Participants were recruited using a convince sampling, and data were collected using the free association task. Participants were asked to provide up to five words or phrases that come to mind when thinking about "loud music." The data were first analyzed using the qualitative content analysis. This was followed by quantitative cluster analysis and chi-square analysis. Results: The content analysis suggested 19 main categories of responses related to loud music. The cluster analysis resulted in for main clusters, namely: (1) emotional oriented perception; (2) problem oriented perception; (3) music and enjoyment oriented perception; and (4) positive emotional and recreation-oriented perception. Country of origin was associated with the likelihood of participants being in each of these clusters. Conclusion: The current study highlights the differences and similarities in young adults' perception of loud music. These results may have implications to hearing health education to facilitate healthy listening habits. PMID- 29457603 TI - The hearing of rural workers exposed to noise and pesticides. AB - n work environments, different physical and chemical agents that may pose a risk to workers' hearing health coexist. In this context, occupational hearing loss stands out. It has mostly been attributed to only noise exposure, although there are other agents, that is, pesticides that might contribute to occupational hearing loss. In this report, two cases will be presented that consider rural workers exposed to pesticides and intense noise generated by an adapted rudimentary vehicle. The noise measured in this vehicle was 88.3 dBA up to 93.4 dBA. Pure-tone audiometry, distortion product otoacoustic emissions, and high frequency audiometry tests were performed. This report is unusual because of the short time of exposure to noise and pesticides and the hearing loss found, indicating a synergy between those agents. PMID- 29457604 TI - Cathodal neuromodulation of dominant temporoparietal cortex with transcranial direct current stimulation for tinnitus: A case series. AB - There is scant literature on the effectiveness of using transcranial direct current stimulation (tDCS) as an intervention modality for managing tinnitus. The current case series reflects the use of tDCS as an effective intervention for tinnitus while inhibiting the dominant temporoparietal cortex and simultaneous stimulating the non-dominant dorsolateral prefrontal cortex.

The effect of organic anion, metal cation and synthesis method on developing ultra-high aspect ratio crystallites was studied. PMID- 29457605 TI - Negative Pressure Therapy in the Regeneration of the Sciatic Nerve Using Vacuum - Assisted Closure in a Rabbit Model. AB - BACKGROUND The aim of this study was to investigate the effects of negative pressure therapy in the regeneration of the rabbit sciatic nerve using vacuum assisted closure (VAC). MATERIAL AND METHODS Thirty male New Zealand white rabbits underwent surgical injury of the sciatic nerve, followed by negative pressure therapy using vacuum assisted closure (VAC), in three treatment groups: Group A: 0 kPa; Group B: -20 kPa; Group C: -40 kPa. At 12 weeks following surgery, the following factors were studied: motor nerve conduction velocity (MNCV); the number of myelinated nerve fibers; the wet weight of the gastrocnemius muscle. Gastrocnemius muscle and sciatic nerve tissue samples were studied for the expression of S100, and brain-derived neurotrophic factor (BDNF) using Western blot. RESULTS At 12 weeks following VAC treatment, the MNCV, number of myelinated nerve fibers, and wet weight of the gastrocnemius muscle showed significant differences between the groups (p<0.05), in the following order: Group B >Group A >Group C. The sciatic nerve at 12 weeks following VAC in Group B and Group C showed a significant increase in expression of S100 and BDNF when compared with Group A; no significant differences were detected between Group B and Group C results from Western blot at 12 weeks. CONCLUSIONS The findings of this study, using negative pressure therapy in VAC in a rabbit model of sciatic nerve damage, have shown that moderate negative pressure was beneficial, but high values did not benefit sciatic nerve repair. PMID- 29457608 TI - Redox-responsive UCNPs-DPA conjugated NGO-PEG-BPEI-DOX for imaging-guided PTT and chemotherapy for cancer treatment. AB - The disulfide bond (-S-S-) is an enormously valuable functional group in a variety of chemical and biological agents that display effective reactivity or biological activities (e.g., antitumor activities). The disulfide bonds prevalent in proteins are somewhat oxidizing in the extracellular space; however, such disulfide bonds can rarely be found inside cells because of disulfide cleavage reactions facilitated by abundant free cellular thiols, including glutathione (GSH), which is the most important common thiol-containing small molecule. Interestingly, intracellular GSH concentrations are considerably higher in cancer cells than in analogous normal cells; this feature may prove to be significant in the development of anticancer drug delivery systems (DDS). Moreover, upconversion nanoparticles (UCNPs) have been extensively investigated in multimodal imaging, photodynamic therapy (PDT) and photothermal therapy. UCNPs exploit near-infrared excitation instead of ultraviolet excitation and possess exclusive properties, which include greatly increased penetration depth in biological samples and reductions in background autofluorescence, photobleaching and photodamage to biological specimens. These fascinating optical features of UCNPs may broaden their prospects in the fields of imaging and therapy. Graphene has emerged as a flat monolayer of carbon atoms that are tightly embedded in a two-dimensional (2D) honeycomb lattice. Widespread research has been carried out on graphene in recent years owing to its exclusive shape and size, as well as innumerable fascinating physical and chemical properties. Owing to their high optical absorption in the near-infrared (NIR) region, graphene and GO have been extensively employed for photothermal therapy (PTT). In this study, we attempted to merge the properties of these compounds by conjugating UCNPs and NGO-PEG-BPEI DOX into a single platform for chemotherapy and photothermal therapy. PMID- 29457609 TI - Feedback control of photoresponsive fluid interfaces. AB - Photoresponsive surfactants provide a unique microfluidic driving mechanism. Since they switch between two molecular shapes under illumination and thereby affect surface tension of fluid interfaces, Marangoni flow along the interface occurs. To describe the dynamics of the surfactant mixture at a planar interface, we formulate diffusion-advection-reaction equations for both surfactant densities. They also include adsorption from and desorption into the neighboring fluids and photoisomerization by light. We then study how the interface responds when illuminated by spots of light. Switching on a single light spot, the density of the switched surfactant spreads in time and assumes an exponentially decaying profile in steady state. Simultaneously, the induced radial Marangoni flow reverses its flow direction from inward to outward. We use this feature to set up specific feedback rules, which couple the advection velocities sensed at the light spots to their intensities. As a result two neighboring spots switch on and off alternately. Extending the feedback rule to light spots arranged on the vertices of regular polygons, we observe periodic switching patterns for even sided polygons, where two sets of next-nearest neighbors alternate with each other. A triangle and pentagon also show regular oscillations, while heptagon and nonagon exhibit irregular oscillations due to frustration. While our findings are specific to the chosen set of parameters, they show how complex patterns at photoresponsive fluid interfaces emerge from simple feedback coupling. PMID- 29457613 TI - On the photocatalytic cycle of water splitting with small manganese oxides and the roles of water clusters as direct sources of oxygen molecules. AB - We theoretically studied the chemical principles behind the photodynamics of water splitting: 2H2O + 4hnu + M -> 4H+ + 4e- + O2 + M. To comprehend this simple looking but very complicated reaction, the mechanisms of at least three crucial phenomena, among others, need to be clarified, each of which is supposed to constitute the foundation of chemistry: (i) charge separation (4H+ + 4e-), (ii) the catalytic cycle for essentially the same reactions to be repeated by each of four photon absorptions with a catalyst M, and (iii) the generation of oxygen molecules of spin triplet. We have previously clarified the photodynamical mechanism of charge separation, which we refer to as coupled proton electron wavepacket transfer (CPEWT), based on the theory of nonadiabatic electron wavepacket dynamics [K. Yamamoto and K. Takatsuka, ChemPhysChem, 2017, 18, 537]. CPEWT gives an idea of how charge separation can be materialized at each single photon absorption. Yet, this mechanism alone cannot address the above crucial items such as (ii) the catalytic cycle and (iii) O2 formation. In the studies of these fundamental processes, we constructed a possible minimal chemical system and perform semi-quantitative quantum chemical analyses, with which to attain insights about the possible mechanisms of photochemical water splitting. The present study has been inspired by the idea underlying the so-called Kok cycle, although we do not aim to simulate photosystem II in biological systems in nature. For instance, we assume here that a catalyst M (actually simple manganese oxides in this particular study) is pumped up to its excited states leading to charge separation by four-time photon absorption, each excitation of which triggers individual series of chemical reactions including the reorganization of the hydrogen-bonding network (cluster) of water molecules surrounding the photocatalytic center. It is shown that in the successive processes of restructuring of the relevant water cluster, the O[double bond, length as m dash]O bond is formed and consequently an oxygen molecule of spin triplet can be isolated within a range of a given photon energy of about 3.0 eV. PMID- 29457614 TI - Poly(trimethylene carbonate) and poly(D,L-lactic acid) modify human dendritic cell responses to staphylococci but do not affect Th1 and Th2 cell development. AB - Biomaterial-associated infections (BAIs) are frequent complications in the use of medical devices (biomaterials) correlated with considerable patient discomfort and high treatment costs. The presence of a biomaterial in the host causes derangement of local immune responses increasing susceptibility to infection. Dendritic cells (DCs) have an important role in directing the nature of immune responses by activating and controlling CD4+ T helper (Th) cell responses. To assess the immunomodulatory effect of the combined presence of biomaterials and Staphylococcus aureus (S. aureus) or Staphylococcus epidermidis (S. epidermidis), DC-mediated T cell proliferation and Th1/Th2 cell development were measured using an in vitro human cell system. Poly(trimethylene carbonate) (PTMC) and poly(D,L lactic acid) (PDLLA) modified the production of the DC pro-inflammatory cytokines TNF-alpha, IL-6 and IL-23 in response to S. aureus and S. epidermidis. However, this modified cytokine production did not cause differences in Th1/Th2 cell polarisation, showing a Th1 cell predominance. In the absence of staphylococci, neither of the biomaterials induced DC-mediated T cell proliferation or Th1/Th2 cell polarisation. Moreover, either in the absence or presence of the biomaterials, S. aureus was a more potent inducer of DC cytokine secretion, T cell proliferation and Th1 cell development than S. epidermidis. In conclusion, although PTMC and PDLLA modulated DC cytokine responses to staphylococci, this did not alter the resulting Th cell development. This result suggested that, in this human cell model, Th1/Th2 cell responses were mainly determined by the species of bacteria and that PTMC or PDLLA did not detectably influence these responses.

AB - Heart failure has becoming an increasing medical, economic, and social problem globally. The prevalence of this syndrome is rising, and despite unequivocal positive effects of modern therapy, reduction of mortality has been achieved at the cost of more frequent hospitalisations. Unlike in many European countries, in Poland heart failure is usually recognised later, at a more advanced stage of the disease, leaving less time for ambulatory treatment and resulting in a high number of hospitalisations. The current paper presents the most important data regarding morbidity and mortality due to heart failure in Poland. The experts in the field focus on the key source of high costs of therapy and highlight several critical organisational deficits present in the Polish health care system. This background information builds a basis for a concept of coordinated care for patients with heart failure. The paper discusses the fundamental elements of the system of coordinated care for patients with heart failure necessary to enhance the diagnosis, improve therapeutic effects, and reduce medical, economic, and social costs.

PMID- 29457627 TI - Combination pharmacotherapy for the treatment of fibromyalgia in adults. AB - BACKGROUND: Fibromyalgia is a chronic widespread pain condition affecting millions of people worldwide. Current pharmacotherapies are often ineffective and poorly tolerated. Combining different agents could provide superior pain relief and possibly also fewer side effects. OBJECTIVES: To assess the efficacy, safety, and tolerability of combination pharmacotherapy compared to monotherapy or placebo, or both, for the treatment of fibromyalgia pain in adults. SEARCH METHODS: We searched CENTRAL, MEDLINE, and Embase to September 2017. We also searched reference lists of other reviews and trials registries. SELECTION CRITERIA: Double-blind, randomised controlled trials comparing combinations of two or more drugs to placebo or other comparators, or both, for the treatment of fibromyalgia pain. DATA COLLECTION AND ANALYSIS: From all studies, we extracted data on: participant-reported pain relief of 30% or 50% or greater; patient global impression of clinical change (PGIC) much or very much improved or very much improved; any other pain-related outcome of improvement; withdrawals (lack of efficacy, adverse events), participants experiencing any adverse event, serious adverse events, and specific adverse events (e.g. somnolence and dizziness). The primary comparison was between combination and one or all single agent comparators. We also assessed the evidence using GRADE and created a 'Summary of findings' table. MAIN RESULTS: We identified 16 studies with 1474 participants. Three studies combined a non-steroidal anti-inflammatory drug (NSAID) with a benzodiazepine (306 participants); two combined amitriptyline with fluoxetine (89 participants); two combined amitriptyline with a different agent (92 participants); two combined melatonin with an antidepressant (164 participants); one combined carisoprodol, paracetamol (acetaminophen), and caffeine (58 participants); one combined tramadol and paracetamol (acetaminophen) (315 participants); one combined malic acid and magnesium (24 participants); one combined a monoamine oxidase inhibitor with 5-hydroxytryptophan (200 participants); and one combined pregabalin with duloxetine (41 participants). Six studies compared the combination of multiple agents with each component alone and with inactive placebo; three studies compared combination pharmacotherapy with each individual component but did not include an inactive placebo group; two studies compared the combination of two agents with only one of the agents alone; and three studies compared the combination of two or more agents only with inactive placebo.Heterogeneity among studies in terms of class of agents evaluated, specific combinations used, outcomes reported, and doses given prevented any meta-analysis. None of the combinations of drugs found provided sufficient data for analysis compared with placebo or other comparators for our preferred outcomes. We therefore provide a narrative description of results. There was no or inadequate evidence in any comparison for primary and secondary outcomes. Two studies only reported any primary outcomes of interest (patient reported pain relief of 30%, or 50%, or greater). For each 'Risk of bias' item, only half or fewer of studies had unequivocal low risk of bias. Small size and selective reporting were common as high risk of bias.Our GRADE assessment was therefore very low for primary outcomes of pain relief of 30% or 50% or greater, PGIC much or very much improved or very much improved, any pain-related outcome, participants experiencing any adverse event, any serious adverse event, or withdrawing because of an adverse event.Three studies found some evidence that combination pharmacotherapy reduced pain compared to monotherapy; these trials tested three different combinations: melatonin and amitriptyline, fluoxetine and amitriptyline, and pregabalin and duloxetine. Adverse events experienced by participants were not serious, and where they were reported (in 12 out of 16 studies), all participants experienced them, regardless of treatment. Common adverse events were nausea, dizziness, somnolence, and headache. AUTHORS' CONCLUSIONS: There are few, large, high-quality trials comparing combination pharmacotherapy with monotherapy for fibromyalgia, consequently limiting evidence to support or refute the use of combination pharmacotherapy for fibromyalgia. PMID- 29457628 TI - A coupled in vitro/in vivo approach for engineering a heterologous type III PKS to enhance polyketide biosynthesis in Saccharomyces cerevisiae. AB - Polyketides are attractive compounds for uses ranging from biorenewable chemical precursors to high-value therapeutics. In many cases, synthesis in a heterologous host is required to produce these compounds in industrially relevant quantities. The type III polyketide synthase 2-pyrone synthase (2-PS) from Gerbera hybrida was used for the production of triacetic acid lactone (TAL) in Saccharomyces cerevisiae. Initial in vitro characterization of 2-PS led to the identification of active site variants with improved kinetic properties relative to wildtype. Further in vivo evaluation in S. cerevisiae suggested certain 2-PS mutations altered enzyme stability during fermentation. In vivo experiments also revealed beneficial cysteine to serine mutations that were not initially explored due to their distance from the active site of 2-PS, leading to the design of additional 2-PS enzymes. While these variants showed varying catalytic efficiencies in vitro, they exhibited up to 2.5-fold increases in TAL production when expressed in S. cerevisiae. Coupling of the 2-PS variant [C35S,C372S] to an engineered S. cerevisiae strain led to over 10 g/L TAL at 38% of theoretical yield following fed-batch fermentation, the highest reported to date. Our studies demonstrate the success of a coupled in vitro/in vivo approach to engineering enzymes and provide insight on cysteine-rich enzymes and design principles toward their use in non native microbial hosts. PMID- 29457629 TI - Antibody glycoengineering strategies in mammalian cells. AB - As a key parameter impacting functional and structural heterogeneity, protein glycosylation is a critical quality attribute for antibody biotherapeutic manufacturing. The glycan patterns on recombinant antibodies, particularly on the conserved fragment crystallizable (Fc) region, can have significant effects on an antibody's functional activities including clearance rate, antibody-dependent cellular cytotoxicity (ADCC), complement-dependent cytotoxicity (CDC), and anti inflammatory activity. In this review, we examined specific glycan attachments (fucosylation, sialylation, galactosylation, high-mannose, and bisecting glycans) and their importance to antibody properties. Next, we summarized the recent and current achievements on controlling antibody glycoforms in Chinese hamster ovary (CHO) and other mammalian cells through multiple strategies including genetic engineering, protein engineering, media modification, and other emerging technologies. Further, the impact of one carbohydrate modification on other glycan structures is also described. Finally, approaches to generate desirable homogenous glycan profiles on antibodies are also detailed. By applying multiple complementary intracellular and extracellular strategies, biotechnologists are well on their ways to precisely tuning antibody glycoforms emerging from bioreactors in the coming decades. PMID- 29457630 TI - Combination drug delivery via multilamellar vesicles enables targeting of tumor cells and tumor vasculature. AB - Blood vessel development is critical for the continued growth and progression of solid tumors and, therefore, makes an attractive target for improving cancer therapy. Indeed, vascular-targeted therapies have been extensively explored but they have shown minimal efficacy as monotherapies. Combretastatin A4 (CA-4) is a tubulin-binding vascular disrupting agent that selectively targets the established tumor endothelium, causing rapid vascular beak down. Despite its potent anticancer potential, the drug has dose-limiting side effects, particularly in the form of cardiovascular toxicity. Furthermore, its poor aqueous solubility and the resulting limited bioavailability hinder its antitumor activity in the clinic. To improve the therapeutic efficacy of CA-4, we investigated its application as a combination therapy with doxorubicin (Dox) in a tumor vasculature targeted delivery vehicle: peptide-modified cross-linked multilamellar liposomal vesicles (cMLVs). In vitro cell culture studies showed that a tumor vasculature-targeting peptide, RIF7, could facilitate higher cellular uptake of drug-loaded cMLVs, and consequently enhance the antitumor efficacy in both drug resistant B16 mouse melanoma and human MDA-MB-231 breast cancer cells. In vivo, upon intravenous injection, targeted cMLVs could efficiently deliver both Dox and CA-4 to significantly slow tumor growth through the specific interaction of the targeting peptide with its receptor on the surface of tumor vasculature. This study demonstrates the potential of our novel targeted combination therapy delivery vehicle to improve the outcome of cancer treatment. PMID- 29457631 TI - Non-invasive genetic censusing and monitoring of primate populations. AB - Knowing the density or abundance of primate populations is essential for their conservation management and contextualizing socio-demographic and behavioral observations. When direct counts of animals are not possible, genetic analysis of non-invasive samples collected from wildlife populations allows estimates of population size with higher accuracy and precision than is possible using indirect signs. Furthermore, in contrast to traditional indirect survey methods, prolonged or periodic genetic sampling across months or years enables inference of group membership, movement, dynamics, and some kin relationships. Data may also be used to estimate sex ratios, sex differences in dispersal distances, and detect gene flow among locations. Recent advances in capture-recapture models have further improved the precision of population estimates derived from non invasive samples. Simulations using these methods have shown that the confidence interval of point estimates includes the true population size when assumptions of the models are met, and therefore this range of population size minima and maxima should be emphasized in population monitoring studies. Innovations such as the use of sniffer dogs or anti-poaching patrols for sample collection are important to ensure adequate sampling, and the expected development of efficient and cost effective genotyping by sequencing methods for DNAs derived from non-invasive samples will automate and speed analyses.

AB - Diseases caused by phytopathogenic bacteria are responsible for significant economic losses, and these bacteria spread through diverse pathways including waterways and industrial wastes. It is therefore of high interest to develop potent methods for their eradication. Here, antibacterial properties of direct current atmospheric pressure glow discharge (dc-APGD) generated in contact with flowing bacterial suspensions were examined against five species of phytopathogens. Complete eradication of Clavibacter michiganensis subsp. sepedonicus, Dickeya solani, and Xanthomonas campestris pv. campestris from suspensions of OD600 ~ 0.1 was observed, while there was at least 3.43 logarithmic reduction in population densities of Pectobacterium atrosepticum and Pectobacterium carotovorum subsp. carotovorum. Analysis of plasma-chemical parameters of the dc-APGD system revealed its high rotational temperatures of 2,300 +/- 100 K and 4,200 +/- 200 K, as measured from N2 and OH molecular bands, respectively, electron temperature of 6,050 +/- 400 K, vibrational temperature of 4000 +/- 300 K, and high electron number density of 1.1 * 1015 cm-1 . In addition, plasma treatment led to formation of numerous reactive species and states in the treated liquid, including reactive nitrogen and oxygen species such as NOx , NH, H2 O2 , O2 , O, and OH. Further examination revealed that bactericidal activity of dc-APGD was primarily due to presence of these reactive species as well as to UVA, UVB, and UVC irradiation generated by the dc-APGD source. Plasma treatment also resulted in an increase in temperature (from 24.2 to 40.2 degrees C) and pH (from 6.0 to 10.8) of bacterial suspensions, although these changes had minor effects on cell viability. All results suggest that the newly developed dc-APGD-based system can be successfully implemented as a simple, rapid, efficient, and cost-effective disinfection method for liquids originating from different industrial and agricultural settings.

AB - The recombinant basic fibroblast growth factor (bFGF) containing collagen-binding domain (CBD) has been found to be a potential therapeutic factor in tissue regeneration. However, its binding efficiency and quantification remain uncertain. In this research, massive recombinant bFGFs with good bioactivity for enhancing the proliferation of NIH-3T3 cells were achieved. An ELISA-based quantitative method was set up to investigate the binding efficiency of CBD-bFGFs on collagen films. It indicated that the CBDs significantly increased the collagen-binding ability of bFGF (P < .05), with the optimum binding condition first determined to be in the pH range of 7.5-9.5 (P < .05). Then, the relevant equations to calculate the binding density of bFGF, C-bFGF, and V-bFGF were acquired. Analysis confirmed that the bioactivity of immobilized bFGFs was well correlated with the density of growth factor on collagen films. Based on this research, the density of growth factor is a logical and applicable dosage unit for quantification of binding efficiency of growth factors, rather than traditional concentration of soluble growth factors in tissue engineering applications.

AB - The presence of group-level handedness in non-human primates remains controversial, as different studies have produced inconsistent results. Bimanual coordinated tasks have been found to elicit more pronounced hand preferences than simple unimanual tasks. The aim of this study was to examine manual lateralization in a group of 15 Barbary macaques during unimanual and bimanual tasks. In the unimanual task, data on simple food reaching in a foraging context were collected. During the bimanual task, macaques had to use one hand to hold a tube-shaped apparatus while reaching with the other hand to retrieve the food inside it. Data on the hand use to retrieve food were collected. First, no significant group-level hand preference was found for the unimanual task. However, a significant right hand bias was evident for the bimanual task. At the individual-level, approximately 47% and 67% of the subjects had a significant hand preference in the unimanual and bimanual task respectively. The strength of the hand preference was greater in the bimanual than in the unimanual task. Findings of this study add Macaca sylvanus to the other species showing a right hand preference for coordinated bimanual tasks. Moreover, our results add to the growing body of evidence that bimanual tasks are more suitable and valid measures to investigate handedness in non-human primates. PMID- 29457634 TI - "Cooperative collapse" of the denatured state revealed through Clausius-Clapeyron analysis of protein denaturation phase diagrams. AB - Protein phase diagrams have a unique potential to identify the presence of additional thermodynamic states even when non-2-state character is not readily apparent from the experimental observables used to follow protein unfolding transitions. Two-state analysis of the von Willebrand factor A3 domain has previously revealed a discrepancy in the calorimetric enthalpy obtained from thermal unfolding transitions as compared with Gibbs-Helmholtz analysis of free energies obtained from the Linear Extrapolation Method (Tischer and Auton, Prot Sci 2013; 22(9):1147-60). We resolve this thermodynamic conundrum using a Clausius-Clapeyron analysis of the urea-temperature phase diagram that defines how DeltaH and the urea m-value interconvert through the slope of cm versus T, (?cm/?T)=DeltaH/(mT) . This relationship permits the calculation of DeltaH at low temperature from m-values obtained through iso-thermal urea denaturation and high temperature m-values from DeltaH obtained through iso-urea thermal denaturation. Application of this equation uncovers sigmoid transitions in both cooperativity parameters as temperature is increased. Such residual thermal cooperativity of DeltaH and the m-value confirms the presence of an additional state which is verified to result from a cooperative phase transition between urea-expanded and thermally-compact denatured states. Comparison of the equilibria between expanded and compact denatured ensembles of disulfide-intact and carboxyamidated A3 domains reveals that introducing a single disulfide crosslink does not affect the presence of the additional denatured state. It does, however, make a small thermodynamically favorable free energy (~-13 +/- 1 kJ/mol) contribution to the cooperative denatured state collapse transition as temperature is raised and urea concentration is lowered. The thermodynamics of this "cooperative collapse" of the denatured state retain significant compensations between the enthalpy and entropy contributions to the overall free energy.

AB - Previous studies of nonhuman primates have found relationships between health and individual differences in personality, behavior, and social status. However, despite knowing these factors are intercorrelated, many studies focus only on a single measure, for example, rank. Consequently, it is difficult to determine the degree to which these individual differences are independently associated with health. The present study sought to untangle the associations between health and these individual differences in rhesus macaques (Macaca mulatta). We studied 85 socially housed macaques at the Oregon and California National Primate Research Centers, and used veterinary records to determine the number of injuries and illnesses for each macaque. We measured personality using 12 items from a well established primate personality questionnaire, performed focal observations of behaviors, and calculated dominance status from directional supplant data. All twelve personality questionnaire items were reliable and were used to represent five of the six personality dimensions identified in rhesus macaques-Dominance, Confidence, Openness, Anxiety, and Friendliness (also known as Sociability). Following this, we fit generalized linear mixed effects models to understand how these factors were associated with an animal's history of injury and history of illness. In the models, age was an offset, facility was a random effect, and the five personality dimensions, behavior, sex, and dominance status were fixed effects. Number of injuries and illnesses were each best represented by a negative binomial distribution. For the injury models, including the effects did improve model fit. This model revealed that more confident and more anxious macaques experienced fewer injuries. For the illness models, including the fixed effects did not significantly improve model fit over a model without the fixed effects. Future studies may seek to assess mechanisms underlying these associations. PMID- 29457638 TI - A dialectical behavior therapy skills intervention for women with suicidal behaviors in rural Nepal: A single-case experimental design series. AB - BACKGROUND: Suicide in low- and middle-income countries (LMICs) accounts for 75% of the world's burden of suicide mortality and is the leading single cause of death among Nepali reproductive age women. To advance treatment for suicidal behaviors in LMICs, a single-case experimental design (SCED) was conducted of a culturally adapted Dialectical Behavior Therapy skills intervention for Nepali populations (DBT-N). METHOD: Ten Nepali women with histories of suicidality participated in the 10-session intervention. Outcomes of emotion regulation, suicidal ideation, depression, anxiety, resilience, and coping skills use were measured at multiple time points pre-intervention, during, and at follow-up. Qualitative interviewing assessed DBT-N's feasibility and acceptability. RESULTS: Participants showed improvements in emotion regulation over the course of treatment, which were associated with increased skills use. Rapid, sustained reductions in suicidal ideation and improvements in resilience were observed after DBT-N initiation. CONCLUSION: This SCED supports conducting further evaluation of DBT-N through controlled trials with emotion regulation as a target mechanism of action for reducing suicidal behaviors in LMICs. PMID- 29457639 TI - Hepatitis E virus infection in HIV-infected patients: A large cohort study in Yunnan province, China. AB - Hepatitis E virus (HEV) infection in immunocompromised patients often results in distinct outcome, compared to the infection in general population. This study aimed to investigate the prevalence, potential risk factors, and clinical features of HEV infection among HIV patients treated with antiretroviral therapy (ART) in Yunnan province, China. A total of 770 HIV-infected patients between May 2015 and February 2016 were enrolled in Yunnan, China. All patients received ART. All plasma samples were tested for anti-HEV IgG, anti-HEV IgM antibodies using ELISA kits, and HEV RNA by real-time qRT-PCR. Association between anti-HEV antibody positivity and demographic, clinical and laboratory measures was assessed in univariate and multivariate logistic regression models. Of the 770 HIV-infected patients, 342 patients (44.42%) were anti-HEV IgG antibody positive, and six patients (0.78%) were anti-HEV IgM antibody positive. None of the patients was HEV RNA positive, as tested in our assays. We found that age, gender, CD4 cell count, WHO stage, marital status, and total cholesterol levels were associated with HEV infection. We report a high seroprevalence rate and several potential risk factors of HEV infection in a large HIV cohort from Yunnan province in China. Further research on identification of the circulating HEV strains and the clinical outcome of this patient population is required. PMID- 29457640 TI - Application of adaptive laboratory evolution to overcome a flux limitation in an Escherichia coli production strain. AB - Gene deletion strategies using flux balance analysis (FBA) have improved the growth-coupled production of various compounds. However, the productivities were often below the expectation because the cells failed to adapt to these genetic perturbations. Here, we demonstrate the productivity of the succinate of the designed gene deletion strain was improved by adaptive laboratory evolution (ALE). Although FBA predicted deletions of adhE-pykAF-gldA-pflB lead to produce succinate from glycerol with a yield of 0.45 C-mol/C-mol, the knockout mutant did not produce only 0.08 C-mol/Cmol, experimentally. After the ALE experiments, the highest succinate yield of an evolved strain reached to the expected value. Genome sequencing analysis revealed all evolved strains possessed novel mutations in ppc of I829S or R849S. In vitro enzymatic assay and metabolic profiling analysis revealed that these mutations desensitizing an allosteric inhibition by L-aspartate and improved the flux through Ppc, while the activity of Ppc in the unevolved strain was tightly regulated by L-aspartate. These result demonstrated that the evolved strains achieved the improvement of succinate production by expanding the flux space of Ppc, realizing the predicted metabolic state by FBA.

PMID- 29457642 TI - Identification and characterization of neutralization epitopes at VP2 and VP1 of enterovirus A71. AB - Enterovirus A71 (EV-A71) neutralization escape mutants were generated with monoclonal antibody MAB979 (Millipore). The VP2-T141I and VP1-D14N substitutions were identified. Using reverse genetics, infectious clones with these substitutions were constructed and tested by neutralization assay with immune sera from mice and humans. The N-terminus VP1-14 is more important than EF loop VP2-141 in acute human infection, mainly because it recognised IgM present in acute infection. The N-terminus VP1 could be a useful target for diagnostics and therapeutic antibodies in acute infection.

PMID- 29457645 TI - Research Review: Test-retest reliability of standardized diagnostic interviews to assess child and adolescent psychiatric disorders: a systematic review and meta analysis. AB - BACKGROUND: A better understanding of factors contributing to the observed variability in estimates of test-retest reliability in published studies on standardized diagnostic interviews (SDI) is needed. The objectives of this systematic review and meta-analysis were to estimate the pooled test-retest reliability for parent and youth assessments of seven common disorders, and to examine sources of between-study heterogeneity in reliability. METHODS: Following a systematic review of the literature, multilevel random effects meta-analyses were used to analyse 202 reliability estimates (Cohen's kappa = ?) from 31 eligible studies and 5,369 assessments of 3,344 children and youth. RESULTS: Pooled reliability was moderate at ? = .58 (CI 95% 0.53-0.63) and between-study heterogeneity was substantial (Q = 2,063 (df = 201), p < .001 and I2 = 79%). In subgroup analysis, reliability varied across informants for specific types of psychiatric disorder (? = .53-.69 for parent vs. ? = .39-.68 for youth) with estimates significantly higher for parents on attention deficit hyperactivity disorder, oppositional defiant disorder and the broad groupings of externalizing and any disorder. Reliability was also significantly higher in studies with indicators of poor or fair study methodology quality (sample size <50, retest interval <7 days). CONCLUSIONS: Our findings raise important questions about the meaningfulness of published evidence on the test-retest reliability of SDIs and the usefulness of these tools in both clinical and research contexts. Potential remedies include the introduction of standardized study and reporting requirements for reliability studies, and exploration of other approaches to assessing and classifying child and adolescent psychiatric disorder. PMID- 29457644 TI - Trajectories of frontal brain activity and socio-emotional development in children. AB - Asymmetric frontal brain activity is thought to reflect individual differences in approach- and avoidance-oriented motivation and emotional experience. Using a prospective longitudinal design, the authors investigated whether trajectories of frontal electroencephalogram (EEG) asymmetry in children (Mage = 6.39 years at enrollment) predicted subjective, behavioral, and autonomic indices of socioemotional processes. Resting frontal EEG activity was measured across four separate repeated assessments spanning approximately 2 years. Children's EEG asymmetry across assessments was best characterized by two trajectories: a stable right frontal asymmetry class (48.65%), and a stable left frontal asymmetry class (51.35%). At visit 4, children in the stable right frontal asymmetry displayed more avoidance-related tendencies and children in the stable left frontal asymmetry class exhibited more approach-related tendencies across social, emotional, and autonomic measures. These findings suggest that developmental patterns of resting frontal brain activity across the early school years may underlie approach- and avoidance-related motivation and predict socio-emotional processes in some children. PMID- 29457646 TI - A reexamination of the cognitive behavioral model of chronic fatigue syndrome. AB - OBJECTIVE: The cognitive behavioral model of chronic fatigue syndrome (CFS) suggests that cognitions and reduced activity level perpetuate the fatigue and impairment that individuals with CFS experience. The two empirical evaluations of this model resulted in conflicting findings. The current study examines the influence of case definition fulfillment on the applicability of this model to CFS. METHOD: A moderated mediation analysis was conducted on 990 individuals with CFS to reexamine the behavioral pathway of this model. Case definition fulfillment was entered as a moderator. RESULTS: Findings were generally inconsistent with the cognitive behavioral model of CFS. Case definition fulfillment significantly moderated the relation between activity level and physical impairment (beta = -0.08, p = 0.03); individuals who met more stringent case definitions demonstrated a weaker relation between activity level and impairment. CONCLUSIONS: This model may not accurately represent the experience of individuals with CFS, particularly those who fulfill more stringent case definitions. PMID- 29457647 TI - Learning of hierarchical serial patterns emerges in infancy. AB - Recursive, hierarchically organized serial patterns provide the underlying structure in many cognitive and motor domains including speech, language, music, social interaction, and motor action. We investigated whether learning of hierarchical patterns emerges in infancy by habituating 204 infants to different hierarchical serial patterns and then testing for discrimination and generalization of such patterns. Results indicated that 8- to 10-month-old and 12 to 14-month-old infants exhibited sensitivity to the difference between hierarchical and non-hierarchical structure but that 4- to 6-month-old infants did not. These findings demonstrate that the ability to perceive, learn, and generalize recursive, hierarchical, pattern rules emerges in infancy and add to growing evidence that general-purpose pattern learning mechanisms emerge during the first year of life. PMID- 29457648 TI - Reduction of infection risk mediated by co-culturing Vibrio parahaemolyticus and Listeria monocytogenes in refrigerated cooked shrimp. AB - BACKGROUND: Vibrio parahaemolyticus and Listeria monocytogenes are seafood pathogens of public health significance, and predictive models are effective tools for quantitative microbial risk assessment of these pathogens. However, most current predictive models are based on growth of single strains in broth cultures, and interactions of two or more bacteria in a food matrix can skew the outcomes of the predictions. Therefore, the impact of V. parahaemolyticus and L. monocytogenes when co-cultured and in monoculture on cooked shrimp in cold storage was investigated. RESULTS: The results indicated that L. monocytogenes co cultured with V. parahaemolyticus exhibited reduced growth and longer lag phase at 4 degrees C and 10 degrees C. V. parahaemolyticus exhibited similar behavior when co-cultured with L. monocytogenes at 4 degrees C (death rate K = - 0.67 log10 CFU g-1 day . The death rate K at 10 degrees C when V. parahaemolyticus co cultured with L. monocytogenes was -1.62 log10 CFU g-1 day-1 . There was no significant reduction of growth in monoculture experiments. CONCLUSION: This study has revealed that interaction of V. parahaemolyticus and L. monocytogenes should be considered when quantifying risks posed by these pathogens during consumption of seafood products.

PMID- 29457650 TI - Effects of applying oil-extracted microalgae on the fermentation quality, feed nutritive value and aerobic stability of ensiled sweet sorghum. AB - BACKGROUND: A laboratory-silo study was conducted to evaluate the fermentation quality, feed-nutritive value and aerobic stability of sweet sorghum silage with or without oil-extracted microalgae supplementation. Sweet sorghum was mixed with four microalgae levels (0%, 1%, 2% and 3% on a dry matter basis; control, M1, M2 and M3, respectively) and ensiled for 45 d. Further, the four experimental silages were subjected to an aerobic stability test lasting 7 d. RESULTS: All the silages except M3 silage had good fermentative characteristics with low pH and ammonia nitrogen concentrations, and high lactic acid concentrations and favorable microbial parameters. Meanwhile, oil-extracted microalgae supplementation improved the feed-nutritional value of sweet sorghum silage. Fibre (neutral detergent fibre, acid detergent fibre, acid detergent lignin and cellulose) concentrations decreased, while dry matter and crude protein levels markedly increased (P < 0.05). Compared with the control (69.7 h), treatments M2 and M3 improved the aerobic stability of sweet sorghum silage by 43.8% and more than 143% respectively, and decreased the clostridia spore counts during the stage of air exposure. CONCLUSION: Sweet sorghum silage produced with 2% oil extracted microalgae addition was the most suitable for animal use due to the optimal balance of fermentation quality, feed-nutritional value and aerobic stability, which merits further in vivo studies using grazing ruminants.

AB - Congenital myopathies (CMs) caused by mutation in cofilin-2 gene (CFL2) show phenotypic heterogeneity ranging from early-onset and rapid progressive forms to milder myopathy. Muscle histology is also heterogeneous showing rods and/or myofibrillar changes. Here, we report on three new cases, from two unrelated families, of severe CM related to novel homozygous or compound heterozygous loss of-function mutations in CFL2. Peculiar histopathological changes showed nemaline bodies and thin filaments accumulations together to myofibrillar changes, which were evocative of the muscle findings observed in Cfl2-/- knockout mouse model. PMID- 29457651 TI - Progressive recruitment of contralesional cortico-reticulospinal pathways drives motor impairment post stroke. AB - KEY POINTS: Activation of the shoulder abductor muscles in the arm opposite a unilateral brain injury causes involuntary increases in elbow, wrist and finger flexion in the same arm, a phenomenon referred to as the flexion synergy. It has been proposed that flexion synergy expression is related to reduced output from ipsilesional motor cortex and corticospinal pathways. In this human subjects study, we provide evidence that the magnitude of flexion synergy expression is instead related to a progressive, task-dependent recruitment of contralesional cortex. We also provide evidence that recruitment of contralesional cortex may induce excessive activation of ipsilateral reticulospinal descending motor pathways that cannot produce discrete movements, leading to flexion synergy expression. We interpret these findings as an adaptive strategy that preserves low-level motor control at the cost of fine motor control. ABSTRACT: A hallmark of hemiparetic stroke is the loss of fine motor control in the contralesional arm and hand and the constraint to a grouped movement pattern known as the flexion synergy. In the flexion synergy, increasing shoulder abductor activation drives progressive, involuntary increases in elbow, wrist and finger flexion. The neural mechanisms underlying this phenomenon remain unclear. Here, across 25 adults with moderate to severe hemiparesis following chronic stroke and 18 adults without neurological injury, we test the overall hypothesis that two inter-related mechanisms are necessary for flexion synergy expression: increased task-dependent activation of the intact, contralesional cortex and recruitment of contralesional motor pathways via ipsilateral reticulospinal projections. First, we imaged brain activation in real time during reaching motions progressively constrained by flexion synergy expression. Using this approach, we found that cortical activity indeed shifts towards the contralesional hemisphere in direct proportion to the degree of shoulder abduction loading in the contralesional arm. We then leveraged the post-stroke reemergence of a developmental brainstem reflex to show that anatomically diffuse reticulospinal motor pathways are active during synergy expression. We interpret this progressive recruitment of contralesional cortico reticulospinal pathways as an adaptive strategy that preserves low-level motor control at the cost of fine motor control. PMID- 29457653 TI - How to Create Shared Symbols. AB - Human cognition and behavior are dominated by symbol use. This paper examines the social learning strategies that give rise to symbolic communication. Experiment 1 contrasts an individual-level account, based on observational learning and cognitive bias, with an inter-individual account, based on social coordinative learning. Participants played a referential communication game in which they tried to communicate a range of recurring meanings to a partner by drawing, but without using their conventional language. Individual-level learning, via observation and cognitive bias, was sufficient to produce signs that became increasingly effective, efficient, and shared over games. However, breaking a referential precedent eliminated these benefits. The most effective, most efficient, and most shared signs arose when participants could directly interact with their partner, indicating that social coordinative learning is important to the creation of shared symbols. Experiment 2 investigated the contribution of two distinct aspects of social interaction: behavior alignment and concurrent partner feedback. Each played a complementary role in the creation of shared symbols: Behavior alignment primarily drove communication effectiveness, and partner feedback primarily drove the efficiency of the evolved signs. In conclusion, inter-individual social coordinative learning is important to the evolution of effective, efficient, and shared symbols. PMID- 29457654 TI - Chemoselective Glycosylation of Peptides through S-Alkylation Reaction. AB - An efficient and rapid procedure for synthesizing S-linked glycopeptides is reported. The approach uses activated molecular sieves as a base to promote the selective S-alkylation of readily prepared cysteine-containing peptides, upon reaction of appropriate glycosyl halides. Considering the very mild conditions employed, the chemoselective linkage of the electrophilic sugar with a peptide sulfhydryl group occurred in satisfactory yield, allowing the incorporation of mono and disaccharide moieties. The sugar-peptide conjugates obtained from alpha d-glycosyl derivatives adopt a beta-S-configuration, indicating the high stereoselectivity of the substitution reaction. PMID- 29457655 TI - Importance of growth rate on mercury and polychlorinated biphenyl bioaccumulation in fish. AB - To evaluate the effect of fish growth on mercury (Hg) and polychlorinated biphenyl (PCB) bioaccumulation, a non-steady-state toxicokinetic model, combined with a Wisconsin bioenergetics model, was developed to simulate Hg and PCB bioaccumulation in bluegill (Lepomis macrochirus). The model was validated by comparing observed with predicted Hg and PCB 180 concentrations across 5 age classes from 5 different waterbodies across North America. The non-steady-state model generated accurate predictions for Hg and PCB bioaccumulation in 3 of 5 waterbodies: Apsey Lake (ON, Canada), Sharbot Lake (ON, Canada), and Stonelick Lake (OH, USA). The poor performance of the model for the Detroit River (MI, USA/ON, Canada) and Lake Hartwell (GA/SC, USA), which are 2 well-known contaminated sites with possibly high heterogeneity in spatial contamination, was attributed to changes in feeding behavior and/or prey contamination. Model simulations indicate that growth dilution is a major component of contaminant bioaccumulation patterns in fish, especially during early life stages, and was predicted to be more important for hydrophobic PCBs than for Hg. Simulations that considered tissue-specific growth provided some improvement in model performance particularly for PCBs in fish populations that exhibited changes in their whole body lipid content with age. Higher variation in lipid growth compared with that of lean dry protein was also observed between different bluegill populations, which partially explains the greater variation in PCB bioaccumulation slopes compared with Hg across sampling sites.

PMID- 29457656 TI - Fatty acid binding protein deletion prevents stress-induced preference for cocaine and dampens stress-induced corticosterone levels. AB - Genetic and pharmacological manipulation of endocannabinoid (eCB) signaling has previously been shown to have an important role on the rewarding properties of drugs of abuse, including cocaine. Recently, fatty acid binding proteins (FABPs) have been proposed as intracellular transporters of the endocannabinoid anandamide (AEA) as well as other bioactive lipids to their catabolic enzyme, fatty acid amide hydrolase (FAAH). The role of these transporters in modulating the brains reward system has yet to be investigated. This study examined the effects of genetic deletion of FABP 5/7 on cocaine preference, as assessed by the Conditioned Place Preference (CPP) paradigm. Male and female wild type (WT) and FABP 5/7 KO mice showed similar acquisition of cocaine CPP, with no differences found in overall locomotor activity. In addition, while male and female WT mice showed stress-induced CPP for cocaine, male and female FABP 5/7 KO mice failed to show a stress-induced preference for the cocaine-paired chamber. Additionally, serum corticosterone levels were analyzed to explore any potential differences in stress response that may be responsible for the lack of stress-induced preference for cocaine. Serum samples were obtained in animals under basal conditions as well as following a 30-min tube restraint stress. Male and female FABP 5/7 KO mice showed reduced corticosterone levels under stress compared to their WT counterparts. The reduction in corticosterone response under stress may mediate that lack of a stress-induced preference for cocaine in the FABP 5/7 KO mice. Thus, the role of FABPs may play an important role in drug-seeking behavior under stressful conditions. PMID- 29457657 TI - Semaphorin4A and H-ferritin utilize Tim-1 on human oligodendrocytes: A novel neuro-immune axis. AB - Deficiency of trophic factors relating to the survival of oligodendrocytes, combined with direct interactions with the immune system, are favored paradigms that are increasingly implicated in demyelinating diseases of the central nervous system. We and others have previously shown that Sema4A and H-ferritin interact through the T-cell immunoglobulin and mucin domain (Tim-2) receptor in mice. H ferritin has been identified as the iron delivery protein for oligodendrocytes, whereas Sema4A causes a direct cytotoxic effect. However, the expression of Tim-2 has not been detected in humans. Here, we demonstrate that, similar to rodents, human oligodendrocytes undergo apoptosis when exposed to Sema4A and take up H ferritin for meeting iron requirements and that these functions are mediated via the Tim-1 receptor. Moreover, we also demonstrate the ability of H-ferritin to block Sema4A-mediated cytotoxicity. Furthermore, we show in a series of pilot studies that Sema4A is detectable in the CSF of multiple sclerosis patients and HIV-seropositive persons and can induce oligodendrocyte cell death. Together, these results identify a novel iron uptake mechanism for human oligodendrocytes and a connection between oligodendrocytes and the immune system. PMID- 29457658 TI - Decreased SCIN expression, associated with promoter methylation, is a valuable predictor for prognosis in acute myeloid leukemia. AB - The present study was aimed to investigate SCIN expression as well as promoter methylation and further explore their clinical relevance in acute myeloid leukemia (AML) patients. Real-time quantitative PCR was carried out to detect the expression level of SCIN in 119 AML patients and 37 healthy controls. Real-time quantitative methylation-specific PCR and bisulfite sequencing PCR were carried out to detect SCIN promoter methylation levels in 103 AML patients and 29 controls. As compared with controls, the level of SCIN transcript was significantly down-regulated in AML patients (P = 0.001), and the level of methylated SCIN promoter was significantly higher in AML patients (P = 0.001). Moreover, the level of promoter methylation was weakly negatively correlated with SCIN expression in AML patients (R = -0.265, P = 0.027). Demethylation of SCIN promoter by 5-aza-2'-deoxycytidine could restore its expression in leukemic cell line THP1. The age of SCINlow patients was significantly higher and C/EBPA mutation was significantly less than SCINhigh patients (P = 0.039 and 0.038, respectively). Moreover, the rate of complete remission (CR) of SCINlow patients was significantly lower than SCINhigh patients (P = 0.009). Kaplan-Meier analysis showed that low SCIN expression was associated with shorter overall survival (P = 0.036). Cox regression analysis demonstrated low SCIN expression was an independent poor prognostic factor (P = 0.047). Furthermore, SCIN expression was restored in those patients who achieved CR after induction therapy (P = 0.003). These findings indicate that decreased SCIN expression associated with its promoter methylation is a valuable biomarker for predicting adverse prognosis in AML patients. PMID- 29457659 TI - Improved production, purification, and characterization of biosurfactants produced by Serratia marcescens SM3 and its isogenic SMRG-5 strain. AB - In this study, the biosurfactants (Bs) production of two Serratia marcescens strains (SM3 and its isogenic SMRG-5 strain) was improved and the tenso-active agents were purified and characterized. A 23 factorial design was used to evaluate the effect of nitrogen and carbon sources on the surface tension (ST) reduction and emulsion index (EI24 ) of the produced Bs. Optimum Bs production by SM3 was achieved at high concentrations of carbon and nitrogen, reducing ST to 26.5 +/- 0.28 dynes/cm, with an EI24 of 79.9 +/- 0.2%. Meanwhile, the best results for SMRG-5 were obtained at low concentrations, reducing the ST to 25.2 +/- 0.2 dynes/cm, with an EI24 of 89.7 +/- 0.28%. The optimal conditions for Bs production were scaled up in a 2-L reactor, yielding 4.8 and 5.2 g/L for SM3 and SMRG-5, respectively. Gas Chromatography-Mass Spectrometry (GC-MS) analysis revealed the presence of two different lipopeptides (hidrofobic fractions: octadecanoic and hexadecanoic acid for SM3 and SMRG5, respectively). Both strains were capable of benzo [a] pyrene removal (59% after 72 H of culture). PMID- 29457660 TI - Prevalence of orofacial clefts and risks for nonsyndromic cleft lip with or without cleft palate in newborns at a university hospital from West Mexico. AB - We determined the overall prevalence of typical orofacial clefts and the potential risks for nonsyndromic cleft lip with or without cleft palate in a university hospital from West Mexico. For the prevalence, 227 liveborn infants with typical orofacial clefts were included from a total of 81,193 births occurred during the period 2009-2016 at the "Dr. Juan I. Menchaca" Civil Hospital of Guadalajara (Guadalajara, Jalisco, Mexico). To evaluate potential risks, a case-control study was conducted among 420 newborns, including only those 105 patients with nonsyndromic cleft lip with or without cleft palate (cases), and 315 infants without birth defects (controls). Data were analyzed using multivariable logistic regression analysis expressed as adjusted odds ratio with 95% confidence intervals . The overall prevalence for typical orofacial clefts was 28 per 10,000 (95% confidence interval: 24.3-31.6), or 1 per 358 live births. The mean values for the prepregnancy weight, antepartum weight, and pre-pregnancy body mass index were statistically higher among the mothers of cases. Infants with nonsyndromic cleft lip with or without cleft palate had a significantly higher risk for previous history of any type of congenital anomaly (adjusted odds ratio: 2.7; 95% confidence interval: 1.4-5.1), history of a relative with cleft lip with or without cleft palate (adjusted odds ratio: 19.6; 95% confidence interval: 8.2-47.1), and first-trimester exposures to progestogens (adjusted odds ratio: 6.8; 95% CI 1.8-25.3), hyperthermia (adjusted odds ratio: 3.4; 95% confidence interval: 1.1-10.6), and common cold (adjusted odds ratio: 3.6; 95% confidence interval: 1.1-11.9). These risks could have contributed to explain the high prevalence of orofacial clefts in our region of Mexico, emphasizing that except for history of relatives with cleft lip with or without cleft palate, most are susceptible of modification.

AB - The highly enantioselective totally N-selective hydroxyamination reaction of alpha-aryl-alpha-cyanoacetates with 2-nitrosopyridines was realized by using a chiral N,N'-dioxide/Mg(OTf)2 complex as catalyst, which enriches the nitroso chemistry. A variety of 2-cyano-2-[hydroxyl(pyrydin-2-yl)amino]acetates with quaternary stereocenters and potential antibacterial activities were obtained in excellent yields with good to excellent ee values under as low as 0.05 mol % catalyst loading. The products could be easily transformed to useful alpha-amino amides and 1,2-diamines. Besides, a possible transition state model was proposed to elucidate the origin of the chirality induction. PMID- 29457661 TI - Analysis of 13 C and 14 C labeling in pyruvate and lactate in tumor and blood of lymphoma-bearing mice injected with 13 C- and 14 C-labeled pyruvate. AB - Measurements of hyperpolarized 13 C label exchange between injected [1-13 C]pyruvate and the endogenous tumor lactate pool can give an apparent first-order rate constant for the exchange. The determination of the isotope flux, however, requires an estimate of the labeled pyruvate concentration in the tumor. This was achieved here by measurement of the tumor uptake of [1-14 C]pyruvate, which showed that <2% of the injected pyruvate reached the tumor site. Multiplication of this estimated labeled pyruvate concentration in the tumor with the apparent first-order rate constant for hyperpolarized 13 C label exchange gave an isotope flux that showed good agreement with a flux determined directly by the injection of non-polarized [3-13 C]pyruvate, rapid excision of the tumor after 30 s and measurement of 13 C-labeled lactate concentrations in tumor extracts. The distribution of labeled lactate between intra- and extracellular compartments and the blood pool was investigated by imaging, by measurement of the labeled lactate concentration in blood and tumor, and by examination of the effects of a gadolinium contrast agent and a lactate transport inhibitor on the intensity of the hyperpolarized [1-13 C]lactate signal. These measurements showed that there was significant export of labeled lactate from the tumor, but that labeled lactate in the blood pool produced by the injection of hyperpolarized [1-13 C]pyruvate showed only relatively low levels of polarization. This study shows that measurements of hyperpolarized 13 C label exchange between pyruvate and lactate in a murine tumor model can provide an estimate of the true isotope flux if the concentration of labeled pyruvate that reaches the tumor can be determined.

AB - A hyperbranched polymer with multilayer structure was developed to demonstrate the possibility of highly efficient tandem functionalization reactions at different domains within one nanostructured platform. The polymer scaffold was constructed by chain-growth copper-catalyzed azide-alkyne cycloaddition polymerization of three functional monomers with sequential monomer addition in one pot. Subsequent reactions with different monomer units resulted in efficient functionalization of each segment with construction of a highly sophisticated polymer structure by a robust procedure. As a proof of concept, the ability of this polymer structure to quantitatively load six species of guest molecules through three different types of conjugation reactions was demonstrated. PMID- 29457664 TI - Production and Structural Analysis of Membrane-Anchored Proteins in Phospholipid Nanodiscs. AB - Structural studies on membrane-anchored proteins containing a transmembrane (TM) helix have been hampered by difficulties in producing these proteins in a natively folded form. Detergents that are required to solubilize the hydrophobic TM helix usually destabilize the soluble domain. Thus, TM helices are removed for structural studies, which neglects the pivotal role of a membrane on protein function. This work presents a versatile strategy for the production of this protein class attached to phospholipid nanodiscs. By inserting the TM-helix into nanodiscs and a subsequent SortaseA-mediated ligation of the soluble domain, membrane-anchored BclxL could be obtained in a folded conformation. This strategy is suitable for high-resolution structure determination as well as for probing membrane location by NMR. This method will be applicable to a wide range of membrane-anchored proteins and will be useful to decipher their functional role in a native membrane environment.

AB - In this paper, the in vivo effects of some antibiotics including cefazolin, cefuroxime, and cefoperazon, on the activity of the carbonic anhydrase enzyme (CA) in heart, brain, eye, liver, and kidney tissues of rats were evaluated. For this purpose, 16 different groups, which each containing six rats (n = 6), were formed (control group, cefazolin groups, cefuroxime groups, and cefoperazon groups). The rats were necropsied 60 min after the intraperitoneal injection of the chemicals into the rats. The CA activities were measured for each tissue using esterase activity methods. The activity values for each tissue obtained were statistically calculated. The CA activities in the liver tissue were assessed, and the activities of the cefoperazon groups were decreased compared to the sham groups from the third hour (p < 0.05). In the cefuroxime and cefoperazon groups, the CA activities in the eye tissue were decreased during the first 3 h and then increased (p < 0.05). PMID- 29457665 TI - Comparative analysis of lipid-mediated CRISPR-Cas9 genome editing techniques. AB - CRISPR-Cas technology has revolutionized genome engineering. While Cas9 was not the first programmable endonuclease identified, its simplicity of use has driven widespread adoption in a short period of time. While CRISPR-Cas genome editing holds enormous potential for clinical applications, its use in laboratory settings for genotype-phenotype studies and genome-wide screens has led to breakthroughs in the understanding of many molecular pathways. Numerous protocols have been described for introducing CRISPR-Cas components into cells, and here we sought to simplify and optimize a protocol for genome editing using readily available and inexpensive tools. We compared plasmid, ribonucleoprotein (RNP), and RNA transfection to determine which was method was most optimal for editing cells in a laboratory setting. We limited our comparison to lipofection-mediated introduction because the reagents are widely available. To facilitate optimization, we developed a novel reporter assay to measure gene disruption and the introduction of a variety of exogenous DNA tags. Each method efficiently disrupted endogenous genes and was able to stimulate the introduction of foreign DNA at specific sites, albeit to varying efficiencies. RNP transfection produced the highest level of gene disruption and was the most rapid and efficient method overall. Finally, we show that very short homology arms of 30 base pairs can mediate site-specific editing. The methods described here should broaden the accessibility of RNP-mediated lipofection for laboratory genome-editing experiments.

AB - During this investigation, N,N'-bis-azidomethylamines, N,N'-bis-cyanomethylamine, new alkoxymethylamine and chiral derivatives, which are considered to be a new generation of multifunctional compounds, were synthesized, functional properties were investigated, and anticholinergic and antidiabetic properties of those compounds were studied through the laboratory tests, and it was approved that they contain physiologically active compounds rather than analogues. Novel N-bis cyanomethylamine and alkoxymethylamine derivatives were effective inhibitors of the alpha-glycosidase, cytosolic carbonic anhydrase I and II isoforms, butyrylcholinesterase (BChE), and acetylcholinesterase (AChE) with Ki values in the range of 0.15-13.31 nM for alpha-glycosidase, 2.77-15.30 nM for human carbonic anhydrase isoenzymes I (hCA I), 3.12-21.90 nM for human carbonic anhydrase isoenzymes II (hCA II), 23.33-73.23 nM for AChE, and 3.84-48.41 nM for BChE, respectively. Indeed, the inhibition of these metabolic enzymes has been considered as a promising factor for pharmacologic intervention in a diversity of disturbances. PMID- 29457668 TI - The relationships between depression, neuroticism, and attitudes (NDA model) in heroin abusers in Taiwan. AB - BACKGROUND AND OBJECTIVES: Heroin use is a severe problem worldwide. To develop more effective treatments for heroin abusers, a comprehensive psychosocial model of heroin use should be established and examined. We created and assessed a neuroticism, depression, attitudes, and heroin addiction (NDA) model. METHODS: In this cross-sectional study, 234 patients undergoing methadone replacement treatment were recruited from psychiatric clinics. We used Structural Equation Modeling (SEM) to assess all for neuroticism, depression, and a positive outcome expectancy (POE) (attitudes). RESULTS: The full model had acceptable goodness-of fit indices, but neuroticism was not significantly associated with a POE or heroin use. A reduced model that deleted insignificant paths had better goodness of-fit indices, and neuroticism had indirect effects on heroin use via depression and a POE CONCLUSIONS: Our findings provide evidence that depression, neuroticism, and POE affect heroin use. We also found that POE mediates between depression and heroin use. Despite the emotional regulation strategies recommended to help heroin abusers with depression to reduce the likelihood of their heroin use, teaching them with negative attitudes using heroin should also be considered when developing treatments for heroin abusers with depression. SCIENTIFIC SIGNIFICANCE: Our findings provide a comprehensive mechanism of addiction that is integrated with emotion, cognition, and personality. Drug related beliefs and emotional regulation can be targeted to reduce the likelihood of relapse in abusers with higher levels of neuroticism. (Am J Addict 2018;27:139 143).

AB - Toxicological studies so far suggest that excessive use of malathion, an organophosphate insecticide, causes serious ill-effects in mammalian reproductive physiology. The present study aims at assessing malathion-induced toxicity in a dose- and time-dependent manner with mitigating effects of N-acetyl-l-cysteine. The testicular germ cell viability was monitored using MTT assay, where NAC, being an antioxidant significantly reduced malathion-induced toxicity by enhancing the frequency of cell viability. The histomorphological analysis showed that NAC successfully diminished several apoptotic features in testicular cells, induced by malathion. The differential EB/AO staining revealed a significant decline in the percentage of apoptosis after NAC supplementation. NAC also diminished the malathion-induced DNA fragmentation along with significantly reduction in oxidative stress parameters causing decrease in lipid peroxidation and enhancement of ferric reducing antioxidant power within testicular germ cells. Thus, NAC mitigated the malathion-induced toxicity, proving its potential in infertility treatment. PMID- 29457671 TI - Abstinence and reduced frequency of use are associated with improvements in quality of life among treatment-seekers with cannabis use disorder. AB - BACKGROUND AND OBJECTIVE: Many patients with cannabis use disorder (CUD) do not achieve or do not have abstinence as a goal of treatment, rather they reduce their use. Assessing outcome measures as they relate to functioning and reductions in cannabis use is an important area of study. Quality of life (QoL) shows promise as one such measure. Past studies have demonstrated gender differences in QoL and CUD. We aim to assess (1) the relationship between cannabis use and QoL and (2) gender effects in an outpatient medication treatment study for CUD. METHODS: Data from an 11-weeks, double-blind, placebo-controlled trial of lofexidine and dronabinol for CUD (n = 62) was analyzed. Pearson's correlations between baseline QoL as measured with the Quality of Life, Enjoyment, and Satisfaction Questionnaire-Short Form (QLES-Q-SF) and cannabis use assessed with modified timeline follow-back (TLFB) were examined. Multiple linear regression models of cannabis use on end of study QLES-Q-SF were analyzed, while adjusting for baseline QLES-Q-SF, study arm, and gender. Moderation effects with gender were also tested. RESULTS: No significant association between baseline cannabis use and QoL was found. End of study abstinence (F1,47 = 8.34, p = .006) and reduced proportion of using days (F1,47 = 9.48, p = .004) were each significantly associated with end of study QoL. Reduction in grams (F1,27 = 0.25, p = .62) was not associated with QoL at end of study. Gender was not a significant moderator. DISCUSSION AND CONCLUSIONS: Abstinence and lower frequency of use are associated with higher QoL, regardless of gender. SCIENTIFIC SIGNIFICANCE: This is the first time QoL has been demonstrated to change over the course of CUD medication treatment. QoL is an important outcome in CUD treatment.

PMID- 29457672 TI - Gambling-related cognitive distortions predict level of function among US veterans seeking treatment for gambling disorders. AB - BACKGROUND AND OBJECTIVES: Gambling Disorder (GD) is characterized by recurrent gambling behavior that is associated with significant impairment and distress, high psychiatric comorbidities, and high functional disability. The military veteran population appears particularly susceptible to developing the disorder, but relatively little has been studied among this population. The purpose of the present study is to investigate the clinical psychopathologies and comorbidities of veterans seeking treatment for problem gambling and how problem gambling may impact functioning. METHODS: Treatment-seeking veterans meeting criteria for GD (N = 61) underwent a structured clinical interview and completed the South Oaks Gambling Screen (SOGS), the Gambling Symptom Assessment Scale (G-SAS), the Yale Brown Obsessive-Compulsive Scale for Gambling Disorder (PG-YBOCS), the Gambling Belief Questionnaire (GBQ), the Barratt Impulsiveness Scale (BIS-11), and the Sheehan Disability Scale (SDS). RESULTS: Veterans seeking treatment for GD had high rates of psychiatric and addiction disorder comorbidities. Few veterans had previously sought treatment and most reported substantive challenges in social and occupational functioning. When determining how gambling-related characteristics (ie, severity and cognitive distortions) impact function, severity of cognitive distortions was the strongest statistical predictor of overall functional disability. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: The findings from this study indicate that there is high comorbidity between GD and other psychiatric and addictive disorders, as well as social and occupational functioning. In addition, cognitive distortions related to gambling relate importantly to overall functioning and should be considered in the development of interventions for veterans with GD.

PMID- 29457675 TI - Oocyte-activating capacity of fresh and frozen-thawed spermatids in the common marmoset (Callithrix jacchus). AB - The common marmoset (Callithrix jacchus) represents a promising nonhuman primate model for the study of human diseases because of its small size, ease of handling, and availability of gene-modified animals. Here, we aimed to devise reproductive technology for marmoset spermatid injection using immature males for a possible rapid generational turnover. Spermatids at each step could be identified easily by their morphology under differential interference microscopy: thus, early round spermatids had a round nucleus with a few nucleolus-like structures and abundant cytoplasm, as in other mammals. The spermatids acquired oocyte-activating capacity at the late round spermatid stage, as confirmed by the resumption of meiosis and Ca2+ oscillations upon injection into mouse oocytes. The spermatids could be cryopreserved efficiently with a simple medium containing glycerol and CELL BANKER(r). Late round or elongated spermatids first appeared at 10-12 months of age, 6-8 months before sexual maturation. Marmoset oocytes microinjected with frozen-thawed late round or elongated spermatids retrieved from a 12-month-old male marmoset developed to the 8-cell stage without the need for artificial oocyte activation stimulation. Thus, it might be possible to shorten the intergeneration time by spermatid injection, from 2 years (by natural mating) to 13-15 months including gestation. PMID- 29457674 TI - A review of brain stimulation methods to treat substance use disorders. AB - BACKGROUND: Substance use disorders (SUDs) are a leading cause of disability worldwide. While several pharmacological and behavioral treatments for SUDs are available, these may not be effective for all patients. Recent studies using non invasive neuromodulation techniques including Repetitive Transcranial Magnetic Stimulation (rTMS), Transcranial Direct Current Stimulation (tDCS), and Deep Brain Stimulation (DBS) have shown promise for SUD treatment. OBJECTIVE: Multiple studies were evaluated investigating the therapeutic potential of non-invasive brain stimulation techniques in treatment of SUDs. METHOD: Through literature searches (eg, PubMed, Google Scholar), 60 studies (2000-2017) were identified examining the effect of rTMS, tDCS, or DBS on cravings and consumption of SUDs, including tobacco, alcohol, cannabis, opioids, and stimulants. RESULTS: rTMS and tDCS demonstrated decreases in drug craving and consumption, while early studies with DBS suggest similar results. Results are most encouraging when stimulation is targeted to the Dorsolateral Prefrontal Cortex (DLPFC). CONCLUSIONS: Short term treatment with rTMS and tDCS may have beneficial effects on drug craving and consumption. Future studies should focus on extending therapeutic benefits by increasing stimulation frequency and duration of treatment. SCIENTIFIC SIGNIFICANCE: The utility of these methods in SUD treatment and prevention are unclear, and warrants further study using randomized, controlled designs. (Am J Addict 2018;27:71-91). PMID- 29457676 TI - Subthalamic nucleus pathology contributes to repetitive behavior expression and is reversed by environmental enrichment. AB - Repetitive motor behaviors are common in neurodevelopmental, psychiatric and neurological disorders. Despite their prevalence in certain clinical populations, our understanding of the neurobiological cause of repetitive behavior is lacking. Likewise, not knowing the pathophysiology has precluded efforts to find effective drug treatments. Our comparisons between mouse strains that differ in their expression of repetitive behavior showed an important role of the subthalamic nucleus (STN). In mice with high rates of repetitive behavior, we found significant differences in dendritic spine density, gene expression and neuronal activation in the STN. Taken together, these data show a hypoglutamatergic state. Furthermore, by using environmental enrichment to reduce repetitive behavior, we found evidence of increased glutamatergic tone in the STN with our measures of spine density and gene expression. These results suggest the STN is a major contributor to repetitive behavior expression and highlight the potential of drugs that increase STN function to reduce repetitive behavior in clinical populations. PMID- 29457678 TI - Micronutrient dietary patterns associated with type 2 diabetes mellitus among women of the E3N-EPIC (Etude Epidemiologique aupres de femmes de l'Education Nationale) cohort study. AB - BACKGROUND: Micronutrients play a key role in type 2 diabetes mellitus (T2DM), but methodological difficulties arise from their collinearity and interdependencies with foods. The aim of the present study was to identify micronutrient dietary patterns in the E3N-EPIC (Etude Epidemiologique aupres de femmes de l'Education Nationale) cohort and to investigate their association with risk of T2DM. METHODS: Principal component analysis was used to identify micronutrient patterns among 71 270 women from the E3N-EPIC cohort. Associations between micronutrient patterns and risk of T2DM were quantified by hazard ratios (HRs) and 95% confidence intervals (CIs) from Cox proportional hazards regression models, adjusted for potential confounders. RESULTS: Six micronutrient patterns were identified explaining 78% of the total variance in micronutrient intake. A positive association was found between T2DM and a pattern highly correlated with intake of vitamins B2 and B5 (HR 1.34; 95% CI 1.16-1.56). Similarly, a positive association was found with a pattern characterized by high intakes of vitamin B12 and retinol, and a low intake of vitamin C (HR 1.30; 95% CI 1.15-1.48). An inverse association was observed between T2DM and another two patterns: one correlated with magnesium and vitamin B3 (HR 0.75; 95% CI 0.66-0.86), and the other correlated with manganese intake (HR 0.82; 95% CI 0.72-0.94). CONCLUSIONS: The findings of the present study identify micronutrients that have an effect on the risk of T2DM, and enable better understanding of the complexity of the diet when investigating the association between micronutrients and T2DM. PMID- 29457679 TI - Features of Protonation of the Simplest Weakly Basic Molecules, SO2 , CO, N2 O, CO2 , and Others by Solid Carborane Superacids. AB - An experimental study on protonation of simple weakly basic molecules (L) by the strongest solid superacid, H(CHB11 F11 ), showed that basicity of SO2 is high enough (during attachment to the acidic H atoms at partial pressure of 1 atm) to break the bridged H-bonds of the polymeric acid and to form a mixture of solid mono- LH+ ???An- , and disolvates, L-H+ -L. With a decrease in the basicity of L=CO (via C), N2 O, and CO (via O), only proton monosolvates are formed, which approach L-H+ -An- species with convergence of the strengths of bridged H-bonds. The molecules with the weakest basicity, such as CO2 and weaker, when attached to the proton, cannot break the bridged H-bond of the polymeric superacid, and the interaction stops at stage of physical adsorption. It is shown here that under the conditions of acid monomerization, it is possible to protonate such weak bases as CO2 , N2 , and Xe. PMID- 29457677 TI - The contribution of a negative colorectal screening test result to symptom appraisal and help-seeking behaviour among patients subsequently diagnosed with an interval colorectal cancer. AB - BACKGROUND: Colorectal cancer (CRC) screening programmes using a guaiac faecal occult blood test (gFOBt) reduce CRC mortality. Interval cancers are diagnosed between screening rounds: reassurance from a negative gFOBt has the potential to influence the pathway to diagnosis of an interval colorectal cancer. METHODS: Twenty-six semi-structured face-to-face interviews were carried out in Scotland and England, with individuals diagnosed with an interval colorectal cancer following a negative gFOBt result. RESULTS: Participants reported they were reassured by a negative gFOBt, interpreting their result as an "all clear". Therefore, most did not suspect cancer as a possible cause of symptoms and many did not recall their screening result during symptom appraisal. Among those who did consider cancer, and did think about their screening test result, reassurance from a negative gFOBt led some to "downplay" the seriousness of their symptoms with some interviewees explicitly stating that their negative test result contributed to a delayed decision to seek help. CONCLUSION: Screening participants need to be informed of the limitations of screening and the ongoing risk of developing colorectal cancer even when in receipt of a negative result: the importance of minimizing delay in seeking medical advice for colorectal symptoms should be emphasized. PMID- 29457680 TI - Chronic lead exposure enhances the sympathoexcitatory response associated with P2X4 receptor in rat stellate ganglia. AB - Chronic lead exposure causes peripheral sympathetic nerve stimulation, including increased blood pressure and heart rate. Purinergic receptors are involved in the sympathoexcitatory response induced by myocardial ischemia injury. However, whether P2X4 receptor participates in sympathoexcitatory response induced by chronic lead exposure and the possible mechanisms are still unknown. The aim of this study was to explore the change of the sympathoexcitatory response induced by chronic lead exposure via the P2X4 receptor in the stellate ganglion (SG). Rats were given lead acetate through drinking water freely at doses of 0 g/L (control group), 0.5 g/L (low lead group), and 2 g/L (high lead group) for 1 year. Our results demonstrated that lead exposure caused autonomic nervous dysfunction, including blood pressure and heart rate increased and heart rate variability (HRV) decreased. Western blotting results indicated that after lead exposure, the protein expression levels in the SG of P2X4 receptor, IL-1beta and Cx43 were up-regulated, the phosphorylation of p38 mitogen-activated protein kinase (MAPK) was activated. Real-time PCR results showed that the mRNA expression of P2X4 receptor in the SG was higher in lead exposure group than that in the control group. Double-labeled immunofluorescence results showed that P2X4 receptor was co-expressed with glutamine synthetase (GS), the marker of satellite glial cells (SGCs). These changes were positively correlated with the dose of lead exposure. The up-regulated expression of P2X4 receptor in SGCs of the SG maybe enhance the sympathoexcitatory response induced by chronic lead exposure. PMID- 29457681 TI - Analysis of RPA190 revealed multiple positively selected mutations associated with metalaxyl resistance in Phytophthora infestans. AB - BACKGROUND: Metalaxyl is a phenylamide fungicide, introduced for oomycete management in the 1970s. RPA190 gene has been reported to be associated with metalaxyl resistance, although other genes may also be involved in the process. This study assessed the evolutionary association of amino acid (AA) mutations in RPA190 with metalaxyl resistance in Phytophthora infestans. RESULTS: All isolates from Yunnan were resistant to metalaxyl with multiple AA mutations in RPA190. Two main evolutionary pathways were found in metalaxyl resistance: in one pathway, RPA190 from sensitive isolates (SAA) underwent a single type AA mutation at position 1476, changing from valine to glycine (V1476G); the second pathway involved multiple steps of point mutations. In a phylogenetic tree, nucleotide sequences of the gene clustered into six clades largely corresponding to AA isoform groups. Among the clusters, sequences carrying mutations V1476G and P980S formed two independent clades; other clades shared a common mutation of F382Y. All three mutations together with another two were shown to be under positive selection and the number of AA mutations in an isolate was positively correlated with EC50 values. CONCLUSION: Multiple mutations such as V1476G, P980S, and F382Y in RPA190 contribute to metalaxyl resistance, and resistance to metalaxyl can emerge in at least two independent pathways in P. infestans.

AB - Neuroendocrine carcinoma of the breast is a rare tumor subtype comprising less than 1% of breast cancers in the United States. Merkel cell features within this rare subtype are even rarer. We report a neuroendocrine breast carcinoma with Merkel cell features. The patient underwent breast conservation therapy and a sentinel lymph node biopsy. Unfortunately, the tumor was extremely aggressive and at 5 weeks postoperatively she presented with widely metastatic disease. Due to the aggressive nature of this tumor, we reviewed the literature and treatment options for this rare variant of a rare subtype.

AB - The photochemistry of 1,2-dihydro-1,2-azaborinine derivatives was studied under matrix isolation conditions and in solution. Photoisomerization occurs exclusively to the Dewar valence isomers upon irradiation with UV light (>280 nm) with high quantum yield (46 %). Further photolysis with UV light (254 nm) results in the formation of cyclobutadiene and an iminoborane derivative. The thermal electrocyclic ring-opening reaction of the Dewar valence isomer back to the 1,2 dihydro-1-tert-butyldimethylsilyl-2-mesityl-1,2-azaborinine has an activation barrier of (27.0+/-1.2) kcal mol-1 . In the presence of the Wilkinson catalyst, the ring opening occurs rapidly and exothermically (DeltaH=(-48+/-1) kcal mol-1 ) at room temperature. PMID- 29457685 TI - Tailored Microstructured Hyperpolarizing Matrices for Optimal Magnetic Resonance Imaging. AB - Tailoring the physical features and the porous network architecture of silica based hyperpolarizing solids containing TEMPO radicals, known as HYPSO (hybrid polarizing solids), enabled unprecedented performance of dissolution dynamic nuclear polarization (d-DNP). High polarization values up to P(1 H)=99 % were reached for samples impregnated with a mixture of H2 O/D2 O and loaded in a 6.7 T polarizer at temperatures around 1.2 K. These HYPSO materials combine the best performance of homogeneous DNP formulations with the advantages of solid polarizing matrices, which provide hyperpolarized solutions free of any potentially toxic-additives (radicals and glass-forming agents). The hyperpolarized solutions can be expelled from the porous solids, filtered, and rapidly transferred either to a nuclear magnetic resonance (NMR) spectrometer or to a magnetic resonance imaging (MRI) system. PMID- 29457686 TI - Viable but non-culturable and persistence describe the same bacterial stress state. AB - Bacteria are often thought of as having two dormant phenotypes: the viable but non-culturable (VBNC) state and the persister state. Here we investigate the relatedness of the two stress-induced phenotypes at the single-cell level and examine cell morphology and quantify cell resuscitation. Using the classic starvation conditions to create VBNC cells, we found that the majority of the remaining Escherichia coli population are spherical, have empty cytosol and fail to resuscitate; however, some of the spherical cells resuscitate immediately (most probably those with dense cytosol). Critically, all the culturable cells in this starved population became persister cells within 14 days of starvation. We found that the persister cells initially are rod-like, have clear but limited membrane damage, can resuscitate immediately and gradually become spherical by aging. After 24 h, only rod-shaped persister cells survive, and all the spherical cells lyse. Both cell populations formed under the VBNC-inducing conditions and the persister conditions are metabolically inactive. Therefore, the bacterial population consists of dead cells and persister cells in the VBNC-inducing conditions; that is, the non-lysed particles that do not resuscitate are dead, and the dormant cells that resuscitate are persister cells. Hence, 'VBNC' and 'persister' describe the same dormant phenotype.

AB - Crystallography has shown that human blood group A (GTA) and B (GTB) glycosyltransferases undergo transitions between "open", "semiclosed", and "closed" conformations upon substrate binding. However, the timescales of the corresponding conformational reorientations are unknown. Crystal structures show that the Trp and Met residues are located at "conformational hot spots" of the enzymes. Therefore, we utilized 15 N side-chain labeling of Trp residues and 13 C methyl labeling of Met residues to study substrate-induced conformational transitions of GTB. Chemical-shift perturbations (CSPs) of Met and Trp residues in direct contact with substrate ligands reflect binding kinetics, whereas the CSPs of Met and Trp residues at remote sites reflect conformational changes of the enzyme upon substrate binding. Acceptor binding is fast on the chemical-shift timescale with rather small CSPs in the range of less than approximately 20 Hz. Donor binding matches the intermediate exchange regime to yield an estimate for exchange rate constants of approximately 200-300 Hz. Donor or acceptor binding to GTB saturated with acceptor or donor substrate, respectively, is slow (<10 Hz), as are coupled protein motions, reflecting mutual allosteric control of donor and acceptor binding. Remote CSPs suggest that substrate binding drives the enzyme into the closed state required for catalysis. These findings should contribute to better understanding of the mechanism of glycosyl transfer of GTA and GTB.

AB - Halloysite (Al2 Si2 O5 (OH)4 .nH2 O) nanotubes (HNTs) are natural clay materials and widely applied in many fields due to their natural hollow tubular structures. Many in vitro studies indicate that HNTs exhibit a high level of biocompatibility, however the in vivo toxicity of HNTs remains unclear. The objective of this study was to assess the hepatic toxicity of the purified HNTs in mice via oral route. The purified HNTs were orally administered to mice at 5, 50, and 300 mg/kg body weight (BW) every day for 30 days. Oral administration of HNTs stimulated the growth of the mice at the low dose (5 mg/kg BW) with no liver toxicity, but inhibited the growth of the mice at the middle (50 mg/kg BW) and high (300 mg/kg BW) doses. In addition, oral administration of HNTs at the high dose caused Al accumulation in the liver but had no marked effect on the Si content in the organ. The Al accumulation caused significant oxidative stress in the liver, which induced hepatic dysfunction and histopathologic changes. These findings demonstrated that Al accumulation-induced oxidative stress played an important role in the oral HNTs-caused liver injury.

AB - The ability to survive conditions of low water activity is critical for the survival of many bacteria in the environment and facilitates disease transmission through food and contaminated surfaces. However, the molecular mechanisms that enable bacteria to withstand this condition remain poorly understood. Here we describe a network of regulators in Escherichia coli that are important for this bacterium to survive dehydration. We found that the transcriptional regulator DksA and the general stress response regulator RpoS play a critical role. From a plasmid genomic library screen, we identified two additional regulators, Crl and ArcZ, that promote dehydration tolerance through modulation of RpoS. We also found that LexA, RecA and ArcA contribute to survival. Our results identify key regulators that enable E. coli to tolerate dehydration and suggest a hierarchical network is involved in protection against cellular damage associated with this stress. PMID- 29457690 TI - Carbon Atom Hybridization Matters: Ultrafast Humidity Response of Graphdiyne Oxides. AB - Graphdiyne oxide (GDO), the oxidized form of graphdiyne (GDY), exhibits an ultrafast humidity response with an unprecedented response speed (ca. 7 ms), which is three times faster than that of graphene oxide (GO) with the same thickness and O/C ratio. The ultrafast humidity response of GDO is considered to benefit from the unique carbon hybridization of GDO, which contains acetylenic bonds that are more electron-withdrawing than ethylenic bonds in GO, consequently giving rise to a faster binding rate with water. This distinctive structure-based property enables the fabrication of a novel GDO-based humidity sensor with an ultrafast response speed and good selectivity against other kinds of gas molecules as well as high sensitivity. These properties allow the sensor to accurately monitor the respiration rate change of human and hypoxic rats. PMID- 29457691 TI - Apportioning bacterial carbon source utilization in soil using 14 C isotope analysis of FISH-targeted bacterial populations sorted by fluorescence activated cell sorting (FACS): 14 C-FISH-FACS. AB - An unresolved need in microbial ecology is methodology to enable quantitative analysis of in situ microbial substrate carbon use at the population level. Here, we evaluated if a novel combination of radiocarbon-labelled substrate tracing, fluorescence in situ hybridisation (FISH) and fluorescence-activated cell sorting (FACS) to sort the FISH-targeted population for quantification of incorporated radioactivity (14 C-FISH-FACS) can address this need. Our test scenario used FISH probe PSE1284 targeting Pseudomonas spp. (and some Burkholderia spp.) and salicylic acid added to rhizosphere soil. We examined salicylic acid-14 C fate (mineralized, cell-incorporated, extractable and non-extractable) and mass balance (0-24 h) and show that the PSE1284 population captured ~ 50% of the Nycodenz extracted biomass 14 C. Analysis of the taxonomic distribution of the salicylic acid biodegradation trait suggested that PSE1284 population success was not due to conservation of this trait but due to competitiveness for the added carbon. Adding 50KBq of 14 C sample-1 enabled detection of 14 C in the sorted population at ~ 60-600 times background; a sensitivity which demonstrates potential extension to analysis of rarer/less active populations. Given its sensitivity and compatibility with obtaining a C mass balance, 14 C-FISH-FACS allows quantitative dissection of C flow within the microbial biomass that has hitherto not been achieved.

AB - Nitrous oxide (N2 O) reducing microorganisms may be key in the mitigation of N2 O emissions from managed ecosystems. However, there is still no clear understanding of the physiological and bioenergetic implications of microorganisms possessing either of the two N2 O reductase genes (nosZ), clade I and the more recently described clade II type nosZ. It has been suggested that organisms with nosZ clade II have higher growth yields and a lower affinity constant (Ks ) for N2 O. We compared N2 O reducing communities with different nosZI/nosZII ratios selected in chemostat enrichment cultures, inoculated with activated sludge, fed with N2 O as a sole electron acceptor and growth limiting factor and acetate as electron donor. From the sequencing of the 16S rRNA gene, FISH and quantitative PCR of nosZ and nir genes, we concluded that betaproteobacterial denitrifying organisms dominated the enrichments with members within the family Rhodocyclaceae being highly abundant. When comparing cultures with different nosZI/nosZII ratios, we did not find support for (i) a more energy conserving N2 O respiration pathway in nosZ clade II systems, as reflected in the growth yield per mole of substrate, or (ii) a higher affinity for N2 O, defined by MUmax /Ks , in organisms with nosZ clade II. PMID- 29457694 TI - Exploring effects of self-management on glycemic control using a modified information-motivation-behavioral skills model in type 2 diabetes mellitus patients in Shanghai, China: A cross-sectional study. AB - BACKGROUND: The original information-motivation-behavioral skills (IMB) model has been verified in type 2 diabetes mellitus (T2DM) patients, but the effects of the model on glycemic control remain unclear. The aim of this study was to modify the IMB model to explore the effects of self-management on glycemic control in T2DM patients in Shanghai, China. METHODS: A cross-sectional study was conducted on participants recruited using a convenience sampling method between June and August 2015 in three tertiary hospitals and four community health service centers; 796 participants meeting the inclusion criteria (age >=18 years and a diagnosis of T2DM) completed a questionnaire and blood test for glycemic control. Structural equation models were used to test the IMB framework. RESULTS: The modified model demonstrated an acceptable fit of the data. Paths from information to self-management behaviors (beta = 0.119, P = 0.001) and HbA1c (beta = -0.140, P < 0.001), from motivation to behavioral skills (beta = 0.670, P < 0.001), from behavioral skills to self-management behaviors (beta = 0.562, P < 0.001), and from self-management behaviors to HbA1c (beta = -0.343, P < 0.001) were all significant and in the predicted direction. Information and motivation varied with each other (r = 0.350, P < 0.001). CONCLUSIONS: Glycemic control can be incorporated into the IMB model. The utility of the modified model in the study population is validated. Type 2 diabetes mellitus patients with poor control of glucose levels may be a better target population for application of the modified IMB model. PMID- 29457695 TI - Functionalization of a nanostructured hydroxyapatite with Cu(II) compounds as a pesticide: in situ transmission electron microscopy and environmental scanning electron microscopy observations of treated Vitis vinifera L. leaves. AB - BACKGROUND: The present study evaluated a biocompatible material for plant protection with the aim of reducing the amount of active substance applied. We used a synthetic hydroxyapatite (HA) that has been studied extensively as a consequence of its bioactivity and biocompatibility. An aggregation between HA nanoparticles and four Cu(II) compounds applied to Vitis vinifera L. leaves as a pesticide was studied. Formulations were characterized by X-ray diffraction (XRD), dynamic light scattering (DLS) and electron microscopy and applied in planta to verify particle aggregation and efficiency in controlling the pathogen Plasmopara viticola. RESULTS: The XRD patterns showed different crystalline phases dependig on the Cu(II) compound formulated with HA particles, DLS showed that nanostructured particles are stable as aggregates out of the nanometer range and, in all formulations, transmission electron microscopy (TEM) and environmental scanning electron microscopy (ESEM) microscopy showed large aggregates which were partially nanostructured and were recognized as stable in their micrometric dimensions. Such particles did not show phytotoxic effects after their application in planta. CONCLUSION: A formulation based on HA and a soluble Cu(II) compound showed promising results in the control of the fungal pathogen, confirming the potential role of HA as an innovative delivery system of Cu(II) ions. The present work indicates the possibility of improving the biological activity of a bioactive substance by modifying its structure through an achievable formulation with a biocompatible material.

AB - Based on the modal analysis method, we developed a model that describes the output beam of a diode-pumped solid state (DPSS) laser emitting a multimode beam. Measuring the output beam profile in the near field and at the constructed far field the individual modes, their respective contributions, and their optical parameters are determined. Using this information, the beam is optically reshaped into a quasi-Gaussian beam by the interference and superposition of the various modes. This process is controlled by a mode modulator unit that includes different meso-aspheric elements and a soft-aperture. The converted beam is guided into a second optical unit comprising achromatic-aspheric elements to produce a thin light sheet for ultramicroscopy. We found that this light sheet is markedly thinner and exhibits less side shoulders compared with a light sheet directly generated from the output of a DPSS multimode laser. PMID- 29457698 TI - Feasibility of a novel tacking method of securing mesh in transabdominal preperitoneal inguinal hernia repair: Secure tacking against recurrence. AB - INTRODUCTION: Postoperative chronic pain is an important outcome of hernia surgery. In laparoscopic hernia surgery, either fixation outside the trapezoid of disaster or no fixation is recommended to avoid postoperative pain. To avoid recurrence are transabdominal preperitoneal (TAPP) hernia repair, the myopectineal orifice must be covered with mesh during TAPP, but lifting or shrinking of the mesh can lead to recurrence. The aim of this study was to evaluate the feasibility of a novel technique for mesh fixation to prevent the mesh from lifting off. METHODS: After the preperitoneal space was created during TAPP, the anatomy of the lateral cutaneous nerve of the thigh or the femoral branch of the genitofemoral nerve within the trapezoid of disaster was checked. The mesh was tacked at the trapezoid of disaster without nerve injury, and the mesh was fixed with circumferential tacking. We call this procedure secure tacking against recurrence (STAR). We treated 391 adult patients (478 hernias) with TAPP repair; novel tacking was used in some patients (STAR group, 236 hernias). The results of the STAR group were retrospectively compared with those of patients in whom we did not use this novel tacking (conventional group, 242 hernias). RESULTS: There was no postoperative chronic pain in either group. There were no cases of hernia recurrence in the STAR group, but there were four cases of hernia recurrence in the conventional group (0% vs 1.7%, P = 0.047). These four recurrences consisted of indirect hernia and mesh lifting on the lateral side. CONCLUSION: The STAR procedure is feasible and safety as a standard procedure for securing the mesh during TAPP. PMID- 29457699 TI - Personality: Distraction or driver in the diagnosis of depression.

AB - OBJECTIVE: Medication adherence among adolescents with cystic fibrosis (CF) is often suboptimal and this has significant impact on their health and quality of life. The purpose of the study was to evaluate the impact of frequent home pulmonary function (PFT) monitoring on medication adherence among adolescents with CF. HYPOTHESIS: We hypothesized that weekly home PFT monitoring will improve adherence while not significantly adding to the treatment burden. METHODS: Individuals aged 12-21 years with CF were provided a spirometer to measure PFTs weekly for 1 year. Results were reviewed weekly via telephone. PFT data were downloaded from the device during quarterly clinic visits. Adherence was calculated from prescription refill data and compared to the previous year. Perceptions of treatment burden were assessed using the CF questionnaire-revised (CFQ-R) quality of life measure. Health outcome measures including nutritional status and PFTs from clinic were collected for the study period and the year prior. RESULTS: Thirty-nine subjects participated in the study. Mean age was 15.89 +/- 2.18 years and 54% were female. Mean adherence to weekly spirometry monitoring was 59.47 +/- 24.60%. Values generated on the device showed good correlation with those obtained in clinic. Mean medication possession ratio (MPR) was 60% in the previous year and 65% during the study (P = 0.04). Mean treatment burden scaled score on the CFQ-R was 68 at enrollment and 66 at study completion (P = 0.14). CONCLUSIONS: Frequent home PFT monitoring is feasible in CF adolescents and could successfully improve medication adherence without significantly impacting treatment burden.

PMID- 29457702 TI - Short time window for transmissibility of African swine fever virus from a contaminated environment. AB - Since the introduction of African swine fever virus (ASFV) into the Baltic states and Poland in 2014, the disease has continued to spread within these regions. In 2017, the virus spread further west and the first cases of disease were reported in the Czech Republic and Romania, in wild boar and domestic pigs, respectively. To control further spread, knowledge of different modes of transmission, including indirect transmission via a contaminated environment, is crucial. Up until now, such an indirect mode of transmission has not been demonstrated. In this study, transmission via an environment contaminated with excretions from ASFV-infected pigs was investigated. Following euthanasia of pigs that were infected with an isolate of ASFV from Poland (POL/2015/Podlaskie/Lindholm), healthy pigs were introduced into the pens, in which the ASFV-infected pigs had been housed. Introduction was performed at 1, 3, 5 or 7 days, following euthanasia of the infected pig groups. Pigs, that were introduced into the contaminated environment after 1 day, developed clinical disease within 1 week, and both ASFV DNA and infectious virus were isolated from their blood. However, pigs introduced into the contaminated pens after 3, 5 or 7 days did not develop any signs of ASFV infection and no viral DNA was detected in blood samples obtained from these pigs within the following 3 weeks. Thus, it was shown that exposure of pigs to an environment contaminated with ASFV can result in infection. However, the time window for transmissibility of ASFV seems very limited, and, within our experimental system, there appears to be a rapid decrease in the infectivity of ASFV in the environment. PMID- 29457703 TI - Exploration of assistive technology for uniform laparoscopic surgery. AB - INTRODUCTION: Laparoscopic surgery is less invasive than open surgery and is now common in various medical fields. However, laparoscopic surgery is more difficult than open surgery and often requires additional time for the operator to achieve mastery. Therefore, we investigated the use of assistive technology for uniform laparoscopic surgery. METHODS: We used the OpenCV2 library for augmented reality with an ArUco marker to detect and estimate forceps positioning. We used Sense HAT as the gyro sensor. The development platforms used were Mac OS X 10.11.3 and Raspberry Pi 3, model B. RESULTS: By attaching the ArUco marker to the needle holder, we could draw a line vertically to the marker. When the needle was held, a cube could be imagined, and both the needle and lines could be used to determine the appropriate position. By attaching the gyro sensor to the camera, we could detect its angle of rotation. We obtained stabilized images by rotating the image by the detected degrees; this was possible for any camera position. CONCLUSIONS: Assistive technology allowed us to obtain consecutive converted images in real time and may be readily applicable to clinical practice. PMID- 29457704 TI - Comparability and repeatability of three commonly used methods for measuring endurance capacity. AB - Measures of endurance (time to exhaustion) have been used to address a wide range of questions in ecomorphological and physiological research, as well as being used as a proxy for survival and fitness. Swimming, stationary (circular) track running, and treadmill running are all commonly used methods for measuring endurance. Despite the use of these methods across a broad range of taxa, how comparable these methods are to one another, and whether they are biologically relevant, is rarely examined. We used Australian water dragons (Intellagama lesueurii), a species that is morphologically adept at climbing, swimming, and running, to compare these three methods of endurance and examined if there is repeatability within and between trial methods. We found that time to exhaustion was not highly repeatable within a method, suggesting that single measures or a mean time to exhaustion across trials are not appropriate. Furthermore, we compared mean maximal endurance times among the three methods, and found that the two running methods (i.e., stationary track and treadmill) were similar, but swimming was distinctly different, resulting in lower mean maximal endurance times. Finally, an individual's endurance rank was not repeatable across methods, suggesting that the three endurance trial methods are not providing similar information about an individual's performance capacity. Overall, these results highlight the need to carefully match a measure of performance capacity with the study species and the research questions being asked so that the methods being used are behaviorally, ecologically, and physiologically relevant.

PMID- 29457707 TI - Peripheral neurostimulation breaks the shuffling steps patterns in Parkinsonian gait: a double blind randomized longitudinal study with Automated Mechanical Peripheral Stimulation. AB - BACKGROUND: The shuffling steps pattern is a typical feature of gait in patients affected by Parkinson's Disease (PD), which progressively reduces their quality of life, being related to the risk of falls in this population. Recently, Automated Mechanical Peripheral Stimulation (AMPS) was presented as an integrative rehabilitative treatment based on peripheral stimulation able to improve the gait spatiotemporal parameters in PD patients. AIM: To evaluate the effects of AMPS on shuffling steps pattern by analyzing the kinematic and spatio temporal gait parameters. DESIGN: Double blind randomized longitudinal study. SETTING: Outpatients. POPULATION: PD patients. METHODS: In this double blind randomized longitudinal study, 14 patients with PD were treated with effective AMPS (AMPS Group), while 14 PD patients were treated with placebo-AMPS (SHAM Group); 32 healthy subjects were deemed the control group (CG). A dedicated medical device (GondolaTM Medical Technologies, Switzerland) was used to deliver both stimulations. Each treatment session lasted about 15 minutes, including preparation (approx. 10 to 13 minutes) and stimulation (approx. 2 minutes). All PD patients were given six AMPS/SHAM treatments sessions, twice a week, delivered during the off-levodopa phase, having withdrawn from dopaminergic medication overnight. We evaluated spatio-temporal and kinematic variables of gait with quantitative 3D-Gait Analysis as follows: before and after the first intervention (acute phase), then after the sixth session (long term phase). RESULTS: We detected differences in all gait variables immediately after the first session of AMPS treatment and again after the sixth stimulation session. CONCLUSIONS: AMPS treatment changes the shuffling steps pattern that is typical of PD subjects, increasing the ROM of hip, knee and ankle joints during the gait cycle. CLINICAL REHABILITATION IMPACT: This data present further evidence that a rehabilitative approach based on the AMPS treatment can induce improvements in the gait pattern of patients affected by PD. PMID- 29457705 TI - Regulation of specialised metabolites in Actinobacteria - expanding the paradigms. AB - The increase in availability of actinobacterial whole genome sequences has revealed huge numbers of specialised metabolite biosynthetic gene clusters, encoding a range of bioactive molecules such as antibiotics, antifungals, immunosuppressives and anticancer agents. Yet the majority of these clusters are not expressed under standard laboratory conditions in rich media. Emerging data from studies of specialised metabolite biosynthesis suggest that the diversity of regulatory mechanisms is greater than previously thought and these act at multiple levels, through a range of signals such as nutrient limitation, intercellular signalling and competition with other organisms. Understanding the regulation and environmental cues that lead to the production of these compounds allows us to identify the role that these compounds play in their natural habitat as well as provide tools to exploit this untapped source of specialised metabolites for therapeutic uses. Here, we provide an overview of novel regulatory mechanisms that act in physiological, global and cluster-specific regulatory manners on biosynthetic pathways in Actinobacteria and consider these alongside their ecological and evolutionary implications. PMID- 29457708 TI - Stress-Enhanced Interlayer Exchange Coupling and Optical-Mode FMR Frequency in Self-Bias FeCoB/Ru/FeCoB Trilayers. AB - Nowadays, the most popular method to increase ferromagnetic resonance (FMR) frequency ( fr) in self-bias soft magnetic films is to improve the anisotropy field HK. However, to push fr to higher frequencies only via raising HK becomes increasingly challenging because fr is already higher than 10 GHz by now. In this study, we fabricated a series of magnetically anisotropic FeCoB/Ru/FeCoB sandwich films possessing antiferromagnetic-like coupling and gradually increased uniaxial stress in the FeCoB sublayers from 52 to 110 MPa. It is quite remarkable that the acoustic mode of FMR gradually disappears, whereas the optical mode is enhanced in these structures. We observed simultaneous enhancement of HK and interlayer coupling field ( JIEC) with the uniaxial stress, which leads to a very pronounced optical-mode frequency increase from 8.67 to 11.62 GHz with a very sensitive stress response of 51 Hz/Pa. In contrast, the fr in a FeCoB single layer (acoustic mode) only varies from 3.47 to 5.05 GHz under similar stress. We believe that the strain-induced electron density variation of the Ru spacer's Fermi surface in the out-of-plane direction is responsible for the enhancement of JIEC. This study demonstrates that the antiferromagnetic coupling is a new route to achieve higher fr and provides the possibility of engineering and manipulating optical-mode resonance simply by controlling the interlayer coupling strength via stress.

AB - Judicious combination of semiconducting polymers with alternating electron donor (D) and acceptor (A) segments created hybrid nanoparticles with amplified energy transfer and red-shifted emission, while simultaneously providing photothermal capabilities. Hybrid D-A polymer particles (H-DAPPs) passively localized within orthotopic breast tumors, serving as bright fluorescent beacons. Laser stimulation induced heat generation on par with gold nanorods, resulting in selective destruction of the tumor. H-DAPPs can also undergo multiple thermal treatments, with no loss of fluorescence intensity or photothermal potential. These results indicate that H-DAPPs provide new avenues for the synthesis of hybrid nanoparticles useful in localized detection and treatment of disease. PMID- 29457710 TI - Investigation of alpha-MnO2 Tunneled Structures as Model Cation Hosts for Energy Storage. AB - Future advances in energy storage systems rely on identification of appropriate target materials and deliberate synthesis of the target materials with control of their physiochemical properties in order to disentangle the contributions of distinct properties to the functional electrochemistry. This goal demands systematic inquiry using model materials that provide the opportunity for significant synthetic versatility and control. Ideally, a material family that enables direct manipulation of characteristics including composition, defects, and crystallite size while remaining within the defined structural framework would be necessary. Accomplishing this through direct synthetic methods is desirable to minimize the complicating effects of secondary processing. The structural motif most frequently used for insertion type electrodes is based on layered type structures where ion diffusion in two dimensions can be envisioned. However, lattice expansion and contraction associated with the ion movement and electron transfer as a result of repeated charge and discharge cycling can result in structural degradation and amorphization with accompanying loss of capacity. In contrast, tunnel type structures embody a more rigid framework where the inherent structural design can accommodate the presence of cations and often multiple cations. Of specific interest are manganese oxides as they can exhibit a tunneled structure, termed alpha-MnO2, and are an important class of nanomaterial in the fields of catalysis, adsorption-separation, and ion-exchange. The alpha MnO2 structure has one-dimensional 2 * 2 tunnels formed by corner and edge sharing manganese octahedral [MnO6] units and can be readily substituted in the central tunnel by a variety of cations of varying size. Importantly, alpha-MnO2 materials possess a rich chemistry with significant synthetic versatility allowing deliberate synthetic control of structure, composition, crystallite size, and defect content. This Account considers the investigation of alpha-MnO2 tunnel type structures and their electrochemistry. Examination of the reported findings on this material family demonstrates that multiple physiochemical properties influence the electrochemistry. The retention of the parent structure during charge and discharge cycling, the material composition including the identity and content of the central cation, the surface condition including oxygen vacancies, and crystallite size have all been demonstrated to impact electrochemical function. The selection of the alpha-MnO2 family of materials as a model system and the ability to control the variables associated with the structural family affirm that full investigation of the mechanisms related to active materials in an electrochemical system demands concerted efforts in synthetic material property control and multimodal characterization, combined with theory and modeling. This then enables more complete understanding of the factors that must be controlled to achieve consistent and desirable outcomes. PMID- 29457711 TI - Small Animal Models for Evaluating Filovirus Countermeasures. AB - The development of novel therapeutics and vaccines to treat or prevent disease caused by filoviruses, such as Ebola and Marburg viruses, depends on the availability of animal models that faithfully recapitulate clinical hallmarks of disease as it is observed in humans. In particular, small animal models (such as mice and guinea pigs) are historically and frequently used for the primary evaluation of antiviral countermeasures, prior to testing in nonhuman primates, which represent the gold-standard filovirus animal model. In the past several years, however, the filovirus field has witnessed the continued refinement of the mouse and guinea pig models of disease, as well as the introduction of the hamster and ferret models. We now have small animal models for most human pathogenic filoviruses, many of which are susceptible to wild type virus and demonstrate key features of disease, including robust virus replication, coagulopathy, and immune system dysfunction. Although none of these small animal model systems perfectly recapitulates Ebola virus disease or Marburg virus disease on its own, collectively they offer a nearly complete set of tools in which to carry out the preclinical development of novel antiviral drugs. PMID- 29457712 TI - Strong Electrochemiluminescence from MOF Accelerator Enriched Quantum Dots for Enhanced Sensing of Trace cTnI. AB - The development of a sensitive and practical electrochemiluminescence (ECL) bioassay relies on the use of ECL signal tags whose signal intensity is high and stable. In this work, strong ECL emission was achieved from metal organic framework (MOF) accelerator enriched quantum dots (CdTe), which were applied as an efficient ECL signal tag for trace biomarker detection. It is particularly noteworthy that a novel mechanism to drastically enhance the ECL intensity of CdTe is established because isoreticular metal organic framework-3 (IRMOF-3) with 2-amino terephthalic acid (2-NH2-BDC) as the organic ligand not only allows for loading a large amount of CdTe via the encapsulating effect and internal/external decoration but also functions as a novel coreactant accelerator for promoting the conversion of coreactant S2O82- into the sulfate radical anion (SO4*-), further boosting the ECL emission of CdTe. On the basis of the simple sandwich immunoreaction approach, cardiac troponin-I antigen (cTnI), a kind of biomarker related with myocardial infarction, was chosen as a detection model using an IRMOF-3-enriched CdTe labeled antibody as the signal probe. This immunosensor demonstrated desirable assay performance for cTnI with a wide response range from 1.1 fg mL-1 to 11 ng mL-1 and a very low detection limit (0.46 fg mL-1). This suggested that the IRMOF-3-enriched CdTe nanocomposite strategy can integrate the coreactant accelerator and luminophore to significantly enhance the ECL intensity and stability, providing a direction for promising ECL tag preparation with broad applications.

AB - In the era of state-of-the-art inhibitor design and high-resolution structural studies, detection of significant but small protein structural differences in the inhibitor-bound forms is critical to further developing the inhibitor. Here, we probed differences in HIV-1 protease (PR) conformation among darunavir and four analogous inhibitor-bound forms and compared them with a drug-resistant mutant using nuclear magnetic resonance chemical shifts. Changes in amide chemical shifts of wild-type (WT) PR among these inhibitor-bound forms, DeltaCSP, were subtle but detectable and extended >10 A from the inhibitor-binding site, asymmetrically between the two subunits of PR. Molecular dynamics simulations revealed differential local hydrogen bonding as the molecular basis of this remote asymmetric change. Inhibitor-bound forms of the drug-resistant mutant also showed a similar long-range DeltaCSP pattern. Differences in DeltaCSP values of the WT and the mutant (DeltaDeltaCSPs) were observed at the inhibitor-binding site and in the surrounding region. Comparing chemical shift changes among highly analogous inhibitors and DeltaDeltaCSPs effectively eliminated local environmental effects stemming from different chemical groups and enabled exploitation of these sensitive parameters to detect subtle protein conformational changes and to elucidate asymmetric and remote conformational effects upon inhibitor interaction.

Atomic force microscopy, space-charge-limited current mobility, surface energy, electron spectroscopy for chemical analysis depth profile, ultraviolet photoelectron spectroscopy analysis, and OPV performance data revealed that the surface status of ZnO changed after inserting the DPPBTDA/PCBM hybrid IFL and induced an optimized blend morphology, having a preferred gradient distribution of the conjugated polymer and PC71BM, for efficient carrier transport. The power conversion efficiency (AM 1.5 G, 1000 W m 2) of the device incorporating the hybrid IFL increased to 9.4 +/- 0.11% from 8.5 +/- 0.15% for the preoptimized PTB7-Th/PCBM device (primarily because of an enhancement in the fill factor from 68.7 +/- 1.1 to 72.1 +/- 0.8%).

AB - Adenosine deamination is one of the most prevalent post-transcriptional modifications in mRNA and is catalyzed by ADAR1 and ADAR2 in humans. ADAR1 and ADAR2 have different substrate selectivity, which is believed to mainly originate from the proteins' deaminase domains (hADAR1d and hADAR2d, respectively). RNA-seq of the Saccharomyces cerevisiae transcriptome subjected to ADAR-catalyzed RNA editing identified substrates with common secondary structure features preferentially edited by hADAR1d over hADAR2d. The relatively small size and efficient reaction of one of these substrates suggested it could be useful for further study of the hADAR1d reaction. Indeed, a short hairpin stem from the S. cerevisiae HER1 mRNA was efficiently deaminated by hADAR1d and used to generate an hADAR1d-specific fluorescent reporter of editing activity. Using substrates preferred by either hADAR1d or hADAR2d in vitro, we found that a chimeric protein bearing an RNA-binding loop from hADAR2d grafted onto hADAR1d showed ADAR2-like selectivity. Finally, a high-throughput mutagenesis analysis (Sat-FACS-Seq) of conserved residues in an RNA-binding loop of hADAR1d revealed essential amino acids for function, advancing our understanding of RNA recognition by this domain.

AB - The synthesis of 4f n Ln3+ complexes of the tris(aryloxide) mesitylene ligand, ((Ad,MeArO)3mes)3-, with Ln = La, Ce, Pr, Sm, and Yb, and their reduction with potassium have revealed that this ligand system can be redox active with some metals. Protonolysis of [Ln(N(SiMe3)2)3] (Ln = La, Ce, Pr, Sm, Yb) with the tris(phenol) (Ad,MeArOH)3mes yielded the Ln3+ complexes [((Ad,MeArO)3mes)Ln] (Ln = La, Ce, Pr, Sm, Yb), 1-Ln. Single electron reduction of each 4f n complex, 1 Ln, using potassium yielded the reduced products, [K(2.2.2 cryptand)][((Ad,MeArO)3mes)Ln] (Ln = La, Ce, Pr, Sm, Yb), 2-Ln. The Sm and Yb complexes have properties consistent with the presence of Ln2+ ions with traditional 4f n+1 electron configurations. However, the La, Ce, and Pr complexes appear to formally contain Ln3+ ions and ((Ad,MeArO)3mes)4- ligands. Structural comparisons of the [((Ad,MeArO)3mes)Ln] and [((Ad,MeOAr)3mes)Ln]1- complexes along with UV-vis absorption and EPR spectroscopy as well as density functional theory calculations support these ground state assignments.

AB - Results of oedometric consolidation experiments linked with small-angle neutron scattering (SANS) measurements are presented, using SWy-2 Wyoming bentonite clay in dry and water-bearing N2 and CO2 atmospheres. Oedometric SANS involves deforming a porous sample under uniaxial strain conditions with applied axial force and internal pore pressure control, and combines with SANS for in situ observation of pore structure evolution and interaction. Scattering from both interlayer (clay intra-aggregate) and free (interaggregate) pores is observed, showing decreasing pore size with dry consolidation and interactions between interlayer and free pore types with swelling and consolidation. Introduction of dry liquid CO2 at zero effective stress (axial stress minus pore pressure) produces large shifts in interlayer scatterers, but is reversible back to pre-CO2 levels upon decreasing pore pressure and increasing effective stress. Introduction of wet liquid CO2, conversely, produces large but irreversible changes in interlayer scatterers, which are interpreted to be the combined result of CO2 and H2O intercalation under hydrostatic conditions, but which diminish with application of effective pressure and consolidation to higher bentonite dry densities. Consideration of CO2 intercalation in smectite-bearing CO2 caprocks needs to include effects of both water and nonhydrostatic stress.

AB - Building on structural and mechanistic studies of lithiated enolates derived from acylated oxazolidinones (Evans enolates) and chiral lithiated amino alkoxides, we found that amino alkoxides amplify the enantioselectivity of aldol additions. The pairing of enantiomeric series affords matched and mismatched stereoselectivities. The structures of mixed tetramers showing 2:2 and 3:1 (alkoxide-rich) stoichiometries are determined spectroscopically. Rate and computational studies provide a viable mechanistic and stereochemical model based on the direct reaction of the 3:1 mixed tetramers, but they raise unanswered questions for the 2:2 mixed aggregates. PMID- 29457719 TI - Fabrication of BSA@AuNC-Based Nanostructures for Cell Fluoresce Imaging and Target Drug Delivery. AB - Drug delivery which can offer efficient and localized drug transportation together with imaging capabilities is highly demanded in the development of cancer theranostic approaches. Herein, we report the construction of bovine serum albumin (BSA) gold nanoclusters (BSA@AuNCs) for cell fluoresce imaging and target drug delivery. BSA@AuNCs were modified with cyclic arginine-glycine-aspartate with the product RGD-BSA@AuNCs to enhance cell internalization of the nanoclusters. Furthermore, doxorubicin hydrochloride or doxorubicin (DOX), a widely used chemotherapy drug, was also used to modify RGD-BSA@AuNCs. The final design of the DOX/RGD-BSA@AuNC system was constructed through the disulfide bond. The physical microstructure and biological characterization of the BSA@AuNCs were realized through high-resolution transmission electron microscopy and confocal laser fluorescence microscopy. As the disulfide bonds were cleaved by glutathione in cancer cells, DOX-SH molecules were released from the nanosystem to inhibit the growth of cancer cells. The as-prepared DOX/RGD-BSA@AuNC system can be used not only to deliver drug but also to achieve the antitumor effect by in vivo imaging, demonstrating its promising applications in cancer treatment.

AB - Anion- and solvent-induced single-crystal-to-single-crystal transformation within an iron(II) triazole system has been generated from {[Fe(TPPT)2Cl2].CHCl3} n (1a) to [Fe(TPPT)(C2O4)0.5Cl(H2O)] n (1b). Luminescence studies indicated that the resultant 1b can be considered as a promising luminescent probe for CrO42- and cyano molecules. PMID- 29457721 TI - Reconstructing Dynamic Promoter Activity Profiles from Reporter Gene Data. AB - Accurate characterization of promoter activity is important when designing expression systems for systems biology and metabolic engineering applications. Promoters that respond to changes in the environment enable the dynamic control of gene expression without the necessity of inducer compounds, for example. However, the dynamic nature of these processes poses challenges for estimating promoter activity. Most experimental approaches utilize reporter gene expression to estimate promoter activity. Typically the reporter gene encodes a fluorescent protein that is used to infer a constant promoter activity despite the fact that the observed output may be dynamic and is a number of steps away from the transcription process. In fact, some promoters that are often thought of as constitutive can show changes in activity when growth conditions change. For these reasons, we have developed a system of ordinary differential equations for estimating dynamic promoter activity for promoters that change their activity in response to the environment that is robust to noise and changes in growth rate. Our approach, inference of dynamic promoter activity (PromAct), improves on existing methods by more accurately inferring known promoter activity profiles. This method is also capable of estimating the correct scale of promoter activity and can be applied to quantitative data sets to estimate quantitative rates. PMID- 29457722 TI - Spatially and Temporally Resolved Detection of Arsenic in a Capillary Dielectric Barrier Discharge by Hydride Generation High-Resolved Optical Emission Spectrometry. AB - A new method for arsenic detection by optical emission spectrometry (OES) is presented. Arsine (AsH3) is generated from liquid solutions by means of hydride generation (HG) and introduced into a capillary dielectric barrier discharge (DBD) where it is atomized and excited. A great challenge in OES is the reduction of the recorded background signal, because it negatively affects the limit of detection (LOD). In conventional DBD/OES methods, the signal intensity of the line of interest, in this case arsenic, is integrated over a long time scale. However, due to the pulsed character of the plasma, the plasma on-time is only a small fraction of the integration time. Therefore, a high amount of noise is added to the actual signal in each discharge cycle. To circumvent this, in the present study the emitted light from the DBD is collected by a fast gated iCCD camera, which is mounted on a modified monochromator. The experimental arrangement enables the recording of the emission signal of arsenic in the form of a monochromatic 2D-resolved picture. The temporal resolution of the iCCD camera in the nanosecond range provides the information at which point in time and how long arsenic is excited in the discharge. With use of this knowledge, it is possible to integrate only the arsenic emission by temporally isolating the signal from the background. With the presented method, the LOD for arsenic could be determined to 93 pg mL-1 with a calibration curve linear over 4 orders of magnitude. As a consequence, the developed experimental approach has a potential for both mechanistic studies of arsine atomization and excitation in DBD plasmas as well as routine applications, in which arsenic determination at ultratrace levels is required. PMID- 29457723 TI - Accurate Quantum Wave Packet Study of the Deep Well D+ + HD Reaction: Product Ro vibrational State-Resolved Integral and Differential Cross Sections. AB - The H+ + H2 reaction and its isotopic variants as the simplest triatomic ion molecule reactive system have been attracting much interests, however there are few studies on the titled reaction at state-to-state level until recent years. In this work, accurate state-to-state quantum dynamics studies of the titled reaction have been carried out by a reactant Jacobi coordinate-based time dependent wave packet approach on diabatic potential energy surfaces constructed by Kamisaka et al. Product ro-vibrational state-resolved information has been calculated for collision energies up to 0.2 eV with maximal total angular momentum J = 40. The necessity of including all K-component for accounting the Coriolis coupling for the reaction has been illuminated. Competitions between the two product channels, (D+ + HD' -> D'+ + HD and D+ + HD' -> H+ + DD') were investigated. Total integral cross sections suggest that resonances enhance the reactivity of channel D+ + HD'-> H+ + DD', however, resonances depress the reactivity of the another channel D+ + HD' -> D'+ + HD. The structures of the differential cross sections are complicated and depend strongly on collision energies of the two channels and also on the product rotational states. All of the product ro-vibrational state-resolved differential cross sections for this reaction do not exhibit rigorous backward-forward symmetry which may indicate that the lifetimes of the intermediate resonance complexes should not be that long. The dynamical observables of this deuterated isotopic reaction are quite different from the reaction of H+ + H2 -> H2 + H+ reported previously.

AB - A simple and straightforward synthesis of isoindolin-1-ones is reported. Exclusive N-cyclization of the amide functional group, an ambident nucleophile, was accomplished for the cyclization of 2-(1-alkynyl)benzamides using n-BuLi I2/ICl. The methodology works with the primary amide and affords the desired isoindolinones in yields of 38-94%. Interestingly, the isolated products exhibit a Z-stereochemistry across the C?C double bond. The reaction mechanism involving the formation of either a vinylic anion or an intimate ion pair intermediate is proposed. PMID- 29457725 TI - Accumulation of Citrulline by Microbial Arginine Metabolism during Alcoholic Fermentation of Soy Sauce. AB - Citrulline, the major precursor of ethyl carbamate in soy sauce, is an intermediate catabolite of arginine produced by bacteria present in soy sauce moromi mash. Pediococcus acidilactici is responsible for the formation of citrulline during the lactic acid fermentation process of soy sauce. However, citrulline accumulation during the alcoholic fermentation process and the corresponding bacteria involved have not been identified. Salt-tolerant, arginine utilizing bacteria were isolated from moromi mash during the alcoholic fermentation process. Under normal cultivation conditions, arginine utilization by these strains did not contribute to citrulline accumulation. However, the conversion of arginine to citrulline by these bacteria increased when cultivated during the alcoholic fermentation process. Additionally, the ethanol-enhanced solubility of free fatty acids in moromi mash stimulated the accumulation of citrulline. Staphylococcus exhibited the highest capability in the conversion of arginine to citrulline. PMID- 29457726 TI - A Robust Oil-in-Oil Emulsion for the Nonaqueous Encapsulation of Hydrophilic Payloads. AB - Compartmentalized structures widely exist in cellular systems (organelles) and perform essential functions in smart composite materials (microcapsules, vasculatures, and micelles) to provide localized functionality and enhance materials' compatibility. An entirely water-free compartmentalization system is of significant value to the materials community as nonaqueous conditions are critical to packaging microcapsules with water-free hydrophilic payloads while avoiding energy-intensive drying steps. Few nonaqueous encapsulation techniques are known, especially when considering just the scalable processes that operate in batch mode. Herein, we report a robust oil-in-oil Pickering emulsion system that is compatible with nonaqueous interfacial reactions as required for encapsulation of hydrophilic payloads. A major conceptual advance of this work is the notion of the partitioning inhibitor-a chemical agent that greatly reduces the payload's distribution between the emulsion's two phases, thus providing appropriate conditions for emulsion-templated interfacial polymerization. As a specific example, an immiscible hydrocarbon-amine pair of liquids is emulsified by the incorporation of guanidinium chloride (GuHCl) as a partitioning inhibitor into the dispersed phase. Polyisobutylene (PIB) is added into the continuous phase as a viscosity modifier for suitable modification of interfacial polymerization kinetics. The combination of GuHCl and PIB is necessary to yield a robust emulsion with stable morphology for 3 weeks. Shell wall formation was accomplished by interfacial polymerization of isocyanates delivered through the continuous phase and polyamines from the droplet core. Diethylenetriamine (DETA) loaded microcapsules were isolated in good yield, exhibiting high thermal and chemical stabilities with extended shelf-lives even when dispersed into a reactive epoxy resin. The polyamine phase is compatible with a variety of basic and hydrophilic actives, suggesting that this encapsulation technology is applicable to other hydrophilic payloads such as polyols, aromatic amines, and aromatic heterocyclic bases. Such payloads are important for the development of extended pot or shelf life systems and responsive coatings that report, protect, modify, and heal themselves without intervention.

AB - Group-V elemental monolayers were recently predicted to exhibit exotic physical properties such as nontrivial topological properties, or a quantum anomalous Hall effect, which would make them very suitable for applications in next-generation electronic devices. The free-standing group-V monolayer materials usually have a buckled honeycomb form, in contrast with the flat graphene monolayer. Here, we report epitaxial growth of atomically thin flat honeycomb monolayer of group-V element antimony on a Ag(111) substrate. Combined study of experiments and theoretical calculations verify the formation of a uniform and single-crystalline antimonene monolayer without atomic wrinkles, as a new honeycomb analogue of graphene monolayer. Directional bonding between adjacent Sb atoms and weak antimonene-substrate interaction are confirmed. The realization and investigation of flat antimonene honeycombs extends the scope of two-dimensional atomically thick structures and provides a promising way to tune topological properties for future technological applications. PMID- 29457728 TI - Modification of the Electrolyte/Electrode Interface for the Template-free Electrochemical Synthesis of Metal Nanowires from Ionic Liquids. AB - In electrochemistry, the electrode/electrolyte interface (EEI) governs the charge/mass-transfer processes and controls the nucleation/growth phenomena. The EEI in ionic liquids (ILs) can be controlled by changing the cation/anion of the IL, salt concentration, electrode potential, and temperature. Here, we show that adding a dopant salt leads to the deposition of nanowires. To illustrate, zinc nanowires were electrodeposited from ZnCl2/1-butyl-1-methylpyrrolidinium trifluoromethylsulfonate in the presence of GaCl3 as a dopant salt. The choice of Zn salt and its ratio to GaCl3 were found to be crucial for Zn nanowires formation. AFM studies revealed that the solvation structure of Au(111)/IL changes significantly in the presence of GaCl3 and ZnCl2. Chronoamperometry showed changes in the nucleation/growth process, consequently leading to the formation of nanowires. A similar approach was adopted to synthesize Sn nanowires. Thus, modification of the EEI by adding a dopant to ILs can be a viable method to obtain nanowires. PMID- 29457729 TI - Assessing Interactions Between a Polytopic Membrane Protein and Lipid Bilayers Using Differential Scanning Calorimetry and Solid-State NMR. AB - It is known that the lipid composition within a cellular membrane can influence membrane protein structure and function. In this Article, we investigated how structural changes to a membrane protein upon substrate binding can impact the lipid bilayer. To carry out this study, we reconstituted the secondary active drug transporter EmrE into a variety of phospholipid bilayers varying in headgroup and chain length and carried out differential scanning calorimetry (DSC) and solid-state NMR experiments. The DSC results revealed a difference in cooperativity of the lipid phase transition for drug-free EmrE protonated at glutamic acid 14 (i.e., proton-loaded form) and the tetraphenylphosphonium (TPP+) bound form of the protein (i.e., drug-loaded form). To complement these findings, we acquired magic-angle-spinning (MAS) spectra in the presence and absence of TPP+ by directly probing the phospholipid headgroup using 31P NMR. These spectra showed a reduction in lipid line widths around the main phase transition for samples where EmrE was bound to TPP+ compared to the drug free form. Finally, we collected oriented solid-state NMR spectra on isotopically enriched EmrE that displayed chemical shift perturbations to both transmembrane and loop residues upon TPP+ binding. All of these results prompt us to propose a mechanism whereby substrate-induced changes to the structural dynamics of EmrE alters the surrounding lipids within the bilayer. PMID- 29457730 TI - Cryospectroscopy Studies of Intact Light-Harvesting Antennas Reveal Empirical Electronic Energy Transitions in Two Cyanobacteria Species. AB - Understanding of electronic energy transition (EET) mechanisms from the light harvesting unit to the reaction center in a natural system has been limited by (a) the use of conventional transient time-resolved spectroscopy at room temperature, which result in high signal-to-noise ratio and (b) examining extracts instead of intact light-harvesting units. Here, we report previously unknown differences and new insight in EET of two cyanobacteria species, Acaryochloris marina and Thermosynechoccocus vulcanus, which have been found only after using UV-vis, hole-burning, and fluorescence spectroscopy at ultralow temperature and examining their intact light-harvesting unit, phycobilisomes (PBS). Although the exciton formation is similarly induced by photoexcitation of chromophore assemblies in phycocyanin (PC) and allophycocyanin (APC) in PBSs of both species, the EET mechanisms are totally different, being adiabatic in A. marina and nonadiabatic in T. vulcanus. The PBS of A. marina has only one APC trimer and energy transfer is through coupling of alpha84 in APC with beta84 in adjacent PC. In T. vulcanus, the PBS has three components: coupling between APC core and the entire PC rod and couplings of beta-beta18 and of LCM to beta in the adjacent APC-like trimer. A total of 80% of the excitation energy is trapped in the coupling beta-beta18 and regulates the flow of energy from the high- to low level terminal electronic transition emitter beta-LCM. All these details cannot be observed at room temperature and in extracted units. PMID- 29457731 TI - Synthesis of Structurally Diverse Emissive Molecular Rotors with Four-Component Ugi Stators. AB - The use of the multicomponent Ugi reaction to rapidly prepare a library of dumbbell-like molecular rotors is highlighted here. The synthetic strategy consisted of the atom-economic access to 15 bulky and structurally diverse iodinated stators, which were cross-coupled to the 1,4-diethynylphenylene rotator. From those experiments, up to six rotors 1a-c and 1l-n were obtained, with yields ranging from 35 to 69% per coupled C-C bond. In addition to the framework diversity, five of these compounds showed aggregate-enhanced emission properties thanks to their conjugated 1,4-bis(phenylethynyl)benzene cores, a property that rises by increasing the water fraction (fw) in their THF solutions. The results highlight the significance of the diversity-oriented synthesis of rapid access to new molecular fluorescent rotors.

AB - Full details of our synthetic studies toward plusbacin A3 (1), which is a depsipeptide with antibacterial activity, and its dideoxy derivative are described. To establish an efficient synthetic route of 1, a solvent-dependent diastereodivergent Joullie-Ugi three-component reaction (JU-3CR) was used to construct trans-Pro(3-OH) in a small number of steps. Two strategies were investigated toward the total synthesis. In the first synthetic strategy, the key steps were the trans-selective JU-3CR and a macrolactonization at the final stage of the synthesis. The JU-3CR using alkyl isocyanides in 1,1,1,3,3,3 hexafluoroisopropanol provided the trans products, and the coupling of the fragments to prepare the macrocyclization precursor proceeded smoothly. However, attempts toward the macrolactonization did not provide the desired product. Then, the second strategy that included esterification in an initial stage was investigated. Methods for constructing trans-Pro(3-OH) were examined using a convertible isocyanide, which could be converted to a carboxylic acid required for the following amidation. Ester bond formation was achieved through an intermolecular coupling using a hydroxyl-Asp derivative and the corresponding alcohol, and the amidation afforded a linear depsipeptide. The macrolactamization of the linear peptide gave the cyclic depsipeptide, and then the global deprotection accomplished the total synthesis of 1 and its dideoxy derivative.

A variety of alkenes, including mono-, di-, and trisubstituted alkenes, could all smoothly convert to structural diversified cinnamates in this protocol. Interestingly, when the hydroxyl-containing alkenes were used, various lactones could be rapidly assembled. Moreover, this protocol could be applied to late-stage functionalization of natural products.

AB - Klebsiella pneumoniae and Escherichia coli form mixed species biofilms in catheter-associated urinary tract infections. Recently, a detrimental effect of K. pneumoniae over E. coli was observed in mixed species biofilms grown in an artificial urine medium. The mechanism behind this competitive interaction was studied. K. pneumoniae partially outcompeted E. coli in early-stage batch-fed biofilms, whereas both microorganisms co-exist at longer times (K. pneumoniae:E. coli ratio, 55:1), as shown by cell counts and confocal microscopy. E. coli cells were scattered along the K. pneumoniae biofilm. Biofilm supernatants did not appear to contain either antimicrobial or anti-biofilm activities against E. coli. Biofilms grown under continuous flow prevented interspecies competition. K. pneumoniae showed both increased siderophore production and better growth in iron limited media compared to E. coli. In summary, these results indicate the importance of nutrient (particularly iron) competition in the modulation of the bacterial composition of mixed species biofilms formed by uropathogenic K. pneumoniae and E. coli.

The total extract was then partitioned into four fractions including chloroform, ethyl acetate and methanol. Cytotoxic effect of fractions was examined by MTT assay in K562 (chronic myelogenous leukemia), AGS (gastric adenocarcinoma), MCF-7 (breast adenocarcinoma) and SW742 (colon adenocarcinoma) cell lines. The Chloroform fraction, with the lowest LC50 against K-562 cell lines, was partitioned into 14 subfractions and subjected to further purification by reversed-phase (C18) silica gel and sephadex LH-20 column chromatography. Three flavonoids including cirsimaritin, cirsilinelol and eupatilin were isolated for the first time from the species and the structures were confirmed by spectroscopic data. The high selectivity index of the purified flavonoids indicates valuable components with potential few side effects for normal cell lines. However, solubility tests for isolated components indicates the need for novel pharmaceutical dosage forms, in the case for using natural flavonoids as chemotherapeutic agents.

PMID- 29457737 TI - Determining the Value of Cerebrospinal Fluid Lactate Dehydrogenase Level in Differentiating Subarachnoid Hemorrhage From Traumatic Lumbar Puncture. AB - Context Lumbar puncture (LP) is still an important modality in the diagnosis of subarachnoid hemorrhage (SAH). Rapid and correct fluid analysis can provide patients with a better prognosis by appropriate intervention. Objective To determine the value of cerebrospinal fluid lactate dehydrogenase level in differentiation between SAH and traumatic LP. Design This was a cross-sectional observational study. Patients with a diagnostic suspicion of SAH who were admitted to the emergency department were enrolled in our study based on the inclusion criteria. All patients underwent head computed tomography scan without contrast. Patients with SAH confirmed on computed tomography scan and those who needed surgical intervention underwent LP by the neurosurgical service in the operation room (group 1). Other patients who fulfilled the inclusion criteria but had a traumatic LP in the emergency setting were also enrolled in our study (group 2). The fluid samples of all LPs were sent to the laboratory to be analyzed. Finally, we compared the results of the 2 groups with each other. Results Fifty-two patients were enrolled in our study, 26 patients (50%) from each group. The cerebrospinal fluid lactate dehydrogenase level was significantly higher in group 1 than it was in group 2 ( P < .001), and based on receiver operating characteristic curve analysis, the significant level of cerebrospinal fluid lactate dehydrogenase to differentiate SAH from traumatic LP was estimated to be 185. The red blood cell and white blood cell counts were significantly higher in group 1 than they were in group 2 ( P < .001). Conclusions Cerebrospinal fluid lactate dehydrogenase can effectively differentiate SAH from traumatic tap in LP samples. PMID- 29457738 TI - Reproducibility and Feasibility of Strategies for Morphologic Assessment of Renal Biopsies Using the Nephrotic Syndrome Study Network Digital Pathology Scoring System. AB - Context Testing reproducibility is critical for the development of methodologies for morphologic assessment. Our previous study using the descriptor-based Nephrotic Syndrome Study Network Digital Pathology Scoring System (NDPSS) on glomerular images revealed variable reproducibility. Objective To test reproducibility and feasibility of alternative scoring strategies for digital morphologic assessment of glomeruli and explore use of alternative agreement statistics. Design The original NDPSS was modified (NDPSS1 and NDPSS2) to evaluate (1) independent scoring of each individual biopsy level, (2) use of continuous measures, (3) groupings of individual descriptors into classes and subclasses prior to scoring, and (4) indication of pathologists' confidence/uncertainty for any given score. Three and 5 pathologists scored 157 and 79 glomeruli using the NDPSS1 and NDPSS2, respectively. Agreement was tested using conventional (Cohen kappa) and alternative (Gwet agreement coefficient 1 [AC1]) agreement statistics and compared with previously published data (original NDPSS). Results Overall, pathologists' uncertainty was low, favoring application of the Gwet AC1. Greater agreement was achieved using the Gwet AC1 compared with the Cohen kappa across all scoring methodologies. Mean (standard deviation) differences in agreement estimates using the NDPSS1 and NDPSS2 compared with the single-level original NDPSS were -0.09 (0.17) and -0.17 (0.17), respectively. Using the Gwet AC1, 79% of the original NDPSS descriptors had good or excellent agreement. Pathologist feedback indicated the NDPSS1 and NDPSS2 were time consuming. Conclusions The NDPSS1 and NDPSS2 increased pathologists' scoring burden without improving reproducibility. Use of alternative agreement statistics was strongly supported. We suggest using the original NDPSS on whole slide images for glomerular morphology assessment and for guiding future automated technologies.

AB - To search novel therapy for human colon cancer, scutellarein identified from Scutellaria barbata was investigated using HCT116 cells. As a result, scutellarein can induce apoptosis of HCT116 cells. Further investigation for the mechanism has revealed scutellarein can increase the production of intracellular ROS and lead to the collapse of mitochondrial membrane potential. Meanwhile, the activity of caspase-3 in HCT116 cells was elevated by scutellarein. Moreover, down-regulated Bcl-2 and up-regulated Bax were observed. Additionaly, scutellarein resulted in cytochrome c release from mitochondria. These results indicated the apoptosis induction of HCT116 cells by scutellarein was implemented through ROS-mediated mitochondria-dependent pathway.

AB - The aim of this study was to compare the values of bone-implant contact (BIC) and removal torque (RTQ) reported in different animal studies for titanium-zirconium (TiZr) and titanium (Ti) dental implants. This review has been registered at PROSPERO under number CRD42016047745. We undertook an electronic search for data published up until November 2017 using the PubMed/Medline, Embase, and The Cochrane Library databases. Eligibility criteria included in vivo studies, comparisons between Ti and TiZr implants in the same study, and studies published in English that evaluated BIC and RTQ. After inclusion criteria, 8 studies were assessed for eligibility. Of the 8 studies, 7 analyzed BIC outcome and 3 analyzed RTQ outcome. Among such studies, 6 studies were considered for meta-analysis of quantitative for BIC and 2 studies for RTQ. There was no significant difference for BIC analysis ( P = .89; random ration [RR]: -0.21; 95% confidence interval [CI]: -3.14 to 2.72). The heterogeneity of the primary outcome studies was considered low (7.19; P = .21; I 2 : 30%). However, the RTQ analysis showed different results favoring the TiZr dental implants ( P = .001; RR: 23.62; 95%CI: 9.15 to 38.10). Low heterogeneity was observed for RTQ (chi2: 1.25; P = .26; I 2 : 20%). Within the limitations of this study, there was no difference between TiZr and Ti alloys implants in terms of BIC. However, TiZr implants had higher RTQ than Ti alloys. PMID- 29457741 TI - Lucidumol D, a new lanostane-type triterpene from fruiting bodies of Reishi (Ganoderma lingzhi). AB - A new lanostane-type triterpenoid, lucidumol D (1) was isolated from the fruiting bodies of Ganoderma lingzhi. Its structure was elucidated on the basis of extensive 1D- and 2D-NMR studies as well as mass spectrometry. The cytotoxicity of lucidumol D against proliferation of several cancer cells were assayed by using MTT method and the obtained result suggested selective anti-proliferative and cytotoxic effects against MCF-7, HepG2, HeLa, Caco-2, and HCT-116. In comparison to lucidumol C (2) isolated previously by our group, the structure activity relationship indicated that carbonyl function at C-11 is necessary to enhance the cytotoxicity.

PMID- 29457743 TI - A framework for complexity in palliative care: A qualitative study with patients, family carers and professionals. AB - BACKGROUND: Palliative care patients are often described as complex but evidence on complexity is limited. We need to understand complexity, including at individual patient-level, to define specialist palliative care, characterise palliative care populations and meaningfully compare interventions/outcomes. AIM: To explore palliative care stakeholders' views on what makes a patient more or less complex and insights on capturing complexity at patient-level. DESIGN: In depth qualitative interviews, analysed using Framework analysis. PARTICIPANTS/SETTING: Semi-structured interviews across six UK centres with patients, family, professionals, managers and senior leads, purposively sampled by experience, background, location and setting (hospital, hospice and community). RESULTS: 65 participants provided an understanding of complexity, which extended far beyond the commonly used physical, psychological, social and spiritual domains. Complexity included how patients interact with family/professionals, how services' respond to needs and societal perspectives on care. 'Pre-existing', 'cumulative' and 'invisible' complexity are further important dimensions to delivering effective palliative and end-of-life care. The dynamic nature of illness and needs over time was also profoundly influential. Adapting Bronfenbrenner's Ecological Systems Theory, we categorised findings into the microsystem (person, needs and characteristics), chronosystem (dynamic influences of time), mesosystem (interactions with family/health professionals), exosystem (palliative care services/systems) and macrosystem (societal influences). Stakeholders found it acceptable to capture complexity at the patient-level, with perceived benefits for improving palliative care resource allocation. CONCLUSION: Our conceptual framework encompasses additional elements beyond physical, psychological, social and spiritual domains and advances systematic understanding of complexity within the context of palliative care. This framework helps capture patient-level complexity and target resource provision in specialist palliative care. PMID- 29457744 TI - Optimal safe implantation corridors in feline cervical vertebrae (C2-T1): CT study in 16 domestic shorthair cats. AB - OBJECTIVES: The objective of this study was to define safe corridors for the optimal placement of bicortical implants in the feline cervical spine (C2-T1) using CT. METHODS: CT images of feline cervical spines (n = 16) were reviewed retrospectively. Multiplanar reconstructions were used to define the optimal safe corridors. Safe corridors were defined by their angle of insertion, width and length. The insertion point within the vertebral body was also described. Vertebral measurements were compared between vertebrae using multilevel linear regression, and left and right measurements within vertebrae were compared with the paired samples Wilcoxon signed-rank test. A P value <0.05 was considered significant for all analyses. RESULTS: The safe corridor insertion points were located within the caudal third of the vertebral body in C2 (mean cranial vertebral ratio 0.73) and in the cranial third of the vertebral bodies from C3-T1 (mean cranial vertebral ratios 0.34-0.38). Mean safe corridor widths ranged from 1.04 mm in C2 to 2.30 mm in C7 and T1. The mean right and left optimal angles of implantation were, respectively, 21.79 degrees and 21.49 degrees for C2, 45.26 degrees and 46.19 degrees for C3, 51.48 degrees and 51.04 degrees for C4, 53.52 degrees and 54.30 degrees for C5, 56.36 degrees and 56.65 degrees for C6, 63.40 degrees and 64.92 degrees for C7, and 53.90 degrees and 52.90 degrees for T1. There were statistically significant differences between vertebrae in almost every measurement. CONCLUSIONS AND RELEVANCE: Cervical vertebral safe corridors in cats are narrow and differ to those reported in dogs. Safe corridors are located in the caudal third of C2 and cranial third of the C3 T1 vertebral bodies. Current recommendations for implant sizes should be reviewed, as 1.5-2 mm implants would be oversized for bicortical implantation in most of the feline cervical vertebrae.

AB - The larvicidal potentiality of crude and ethyl acetate extracts of fruits of Acacia auriculiformis was investigated against all the larval instars of JE vector Culex vishnui. The crude extracts showed good results against all the larval instars with highest mortality at 0.09%. Highest mortality was found at 300 ppm of ethyl acetate extract. Lowest LC50 value was obtained at 72 h for third instar larvae. Non target organisms tested, showed no to very less mortality to ethyl acetate solvent extract. Presence of N-H stretching, a C=O stretching, C=C and C-N stretching vibrations of secondary amide or amine group were confirmed from IR analysis. GC-MS analysis revealed the presence of three compounds namely Ethane 2-chloro-1,1-dimethoxy, Acetic acid, 1-methyl ether ester and [4-[1-[3,5-Dimethyl-4[(trimethylsilyl)oxy)phenyl]-1,3-dimethylbutyl) 2,6dimethylphenoxy)(trimethyl) silane, responsible for mosquito larval death. PMID- 29457746 TI - Cardiac rupture caused by traffic accident: Case reports and a literature review. AB - The commonest cause of blunt cardiac injuries is from traffic accidents followed by violent falls, sport activities, accidents or a fight but rupture of the heart is rare and lethal. The precise incidence of cardiac injury after a blunt chest trauma is unknown as rates vary greatly in the literature from between 7% and 76% of cases. Autopsy studies have shown that the right ventricle is the most frequently ruptured, followed by the left ventricle, right atrium, intraventricular septum, left atrium and interatrial septum with decreasing frequency. Post-mortem imaging is a rapidly advancing field of post-mortem investigations of trauma victims. The available literature dealing with the comparison of post-mortem computed tomography results with forensic autopsy indicates that conventional autopsy remains superior for the detection of organ and soft tissue injuries in all body regions.

AB - One new acacic acid-type saponin, named lebbeckoside C (1), was isolated from the stem barks of Albizia lebbeck. Its structure was established on the basis of extensive analysis of 1D and 2D NMR (1H, 13C NMR, DEPT, COSY, TOCSY, ROESY, HSQC and HMBC) experiments, HRESIMS studies, and by chemical evidence as 3-O-[beta-d xylopyranosyl-(l->2)-beta-d-fucopyranosyl-(1->6)-[beta-d-glucopyranosyl(1->2)] beta-d-glucopyranosyl]-21-O-{(2E,6S)-6-O-{4-O-[(2E,6S)-2,6-dimethyl-6-O-(beta-d quinovopyranosyl)octa-2,7-dienoyl]-4-O-[(2E,6S)-2,6-dimethyl-6-O-(beta-d quinovopyranosyl)octa-2,7-dienoyl]-beta-d-quinovopyranosyl}-2,6-dimethylocta-2,7 dienoyl}acacic acid 28 O-[beta-d-quinovopyranosyl-(l->3)-[alpha-l arabinofuranosyl-(l->4)]-alpha-l-rhamnopyranosyl-(l->2)-beta-d-glucopyranosyl] ester. The isolated saponin (1) displayed significant cytotoxic activity against the human glioblastoma cell line U-87 MG and TG1 stem-like glioma cells isolated from a patient tumor with IC50 values of 1.69 and 1.44 MUM, respectively.

AB - As a continuation of our interest in the study of triterpenoid saponins from Albizia zygia, phytochemical investigation of its stem barks led to the isolation of two new oleanane-type saponins, named zygiaosides C-D (1-2). Their structures were established on the basis of extensive analysis of 1D and 2D NMR (1H-, 13C NMR, DEPT, COSY, TOCSY, ROESY, HSQC and HMBC) experiments, HRESIMS studies, and by chemical evidence as, 3-O-[ beta-d-glucopyranosyl-(1->2)-[alpha-l arabinopyranosyl-(1->6)]-beta-d-glucopyranosyl]-21-O-[(2E,6S)-2,6-dimethyl-6-O (beta-d-quinovopyranosyl) octa-2,7-dienoyl]acacic acid 28-O-alpha-l arabinofuranosyl-(1->4)-[beta-d-glucopyranosyl-(1->3)]-alpha-l-rhamnopyranosyl-(1 >2)-beta-d-glucopyranosyl ester (1) and 3- O-[beta-d-glucopyranosyl-(1->2) -[ beta-d-fucopyranosyl-(1->6)]-beta-d-glucopyranosyl]-21-O-[(2E,6S)-2,6-dimethyl-6 O-(beta-D-quinovopyranosyl) octa-2,7-dienoyl]acacic acid 28-O-alpha-l arabinofuranosyl-(1->4)-[beta-d-glucopyranosyl-(1->3)]-alpha-l-rhamnopyranosyl-(1 >2)-beta-d-glucopyranosyl ester (2). PMID- 29457750 TI - Chemical and biological evaluation of essential oil from Saussurea costus (Falc.) Lipsch. from Garhwal Himalaya collected at different harvesting periods. AB - The purpose of this study is the determination of chemical composition and antioxidant activity of essential oils (EOs) from Saussurea costus (Falc.) Lipsch. Roots have been collected on December of the first plant year (IY) and in April, August and December of the third plant year (I, 6B, D7). A GC analysis was carried out for achieving this purpose. Subsequently, total polyphenol content (TPC) and antioxidant activity measured by DPPH, FRAP and BCB assays were evaluated. Three different statistical methods: Relative Antioxidant Capacity Index (RACI), Pearson's correlation coefficient (r) and PCA, were used to compare results obtained and underline EO relationships. From the results obtained, it was possible to observe how the collection period of the EO, in particular both the month and the year of collection, influences the metabolite profile. PMID- 29457749 TI - Chemical and biological studies on Bridelia ferruginea grown in Nigeria. AB - Phytochemical investigation of the methanolic extract of dried leaves of Bridelia ferruginea led to the isolation and identification of fourteen compounds (1-14): compound 1 [mixture of palmitic, stearic and oleic acids], stearyl monoester of 2 O-beta-?-glucosylglycerol (2), 6beta-hydroxy-(20R)-24-ethylcholest-4-en-3-one (3a), 6beta-hydroxy-(20R)-24-ethylcholest-4,22-dien-3-one (3b), lutein (4), vomifoliol (5), corilagin (6), kaempferide-3-O-beta-?-glucoside (7), myricetin (8), isomericitrin (9), isoquercetin (10), myricitrin (11), quercitrin (12), rutin (13), and beta-sitosterol glucoside (14). The total extract exhibited moderate activity towards CB2 receptor and 90% inhibition against leishmanial pathogen Trypanosoma brucei. Compound 4 exhibited 73% displacement in CB2 receptor with IC50 56.47 MUM, and 93% inhibition towards T. brucei with IC50 4.16 MUM. Compound 11 showed 99% inhibition towards Escherichia coli with IC50 1.123 MUM. PMID- 29457752 TI - Accuracy and Bias in Perception of Distress Level and Distress Change Among Same Sex College Student Roommate Dyads. AB - University students often experience high levels of stress and, in some cases, the stress leads to tragic outcomes. An important question is whether roommates can perceive the level and change in distress in their peers. We examined self- and other-reports of 187 same-sex undergraduate dyads at two times in a spring semester. Using the truth and bias model, we found that roommates tended to underestimate their partner's distress at both time points, and that ratings were equally influenced by truth and self-focus bias forces. For change, however, there was no evidence of directional (average) bias, and perceived change was only significantly related to the truth force. There were no consistent moderation effects by closeness or gender. These findings are interpreted in the context of person perception theory and the practical need for early warning about extreme distress in college students. PMID- 29457751 TI - Intra- and inter-fraction uncertainties during IGRT for Wilms' tumor. AB - BACKGROUND AND PURPOSE: To assess intra- and inter-fraction motion uncertainties, due to displacements of the tumor bed (TB) and organs at risk (OAR), as well as intra- and inter-fraction patient set-up uncertainties, due to positioning variations, during image-guided radiation therapy (IGRT) in children with Wilms' tumor. MATERIAL AND METHODS: Four-dimensional computed tomography (4D-CT) and daily pre- and post-treatment cone-beam CT (CBCT)-scans of 15 patients (average 4, range 1-8 years) undergoing flank irradiation after nephrectomy were analyzed. TB (marked by four surgical clips) and OAR motion uncertainties were quantified by displacements of the center of mass in all orthogonal directions. Translational and rotational bone off-sets were recorded for patient set-up uncertainties assessment in all orthogonal directions. The average results, systematic and random errors were computed. RESULTS: Average intra- and inter fraction motion uncertainties were <=1.1 mm (range: [-6.9;7.9] mm) for the TB and <=3.2 mm (range: [-9.1;9.6] mm) for the OAR. Average intra- and inter-fraction patient set-up uncertainties were <=0.1 mm (range: [-3.3;4.8] mm) and <=0.9 degrees (range: [0.0;2.8 degrees ]). Both motion and patient set-up uncertainties were larger for the cranio-caudal direction. Calculated systematic and random errors were <=2.4 mm for the motion uncertainties and <=0.8 mm/0.7 degrees for the patient set-up uncertainties. CONCLUSIONS: Average motion and patient set-up uncertainties during radiotherapy treatment were found to be limited. However, uncertainties were larger for the cranio-caudal direction and outliers were found in all orthogonal directions. When having available 4D-CT and CBCT information, the use of patient-specific and anisotropic safety margin expansions is advised for both target volume and OAR. PMID- 29457753 TI - Bone Strength and Exercise During Youth-The Year That Was 2017. AB - The positive effects of physical activity on bone strength are certain. However, researchers have yet to precisely quantify the contribution of specific characteristics of physical activity that affect bone strength in children and adolescents. This commentary highlights 2 noteworthy 2017 publications that addressed osteogenic physical activity dose-response issues. Both papers moved the field forward by providing new insights on physical activity exposures beyond high-impact loading. Koedijk et al's paper was selected because, to the best of our knowledge, it is the first systematic review to solely examine associations between sedentary behavior and indicators of bone strength. The second selected paper, Gabel et al, used novel approaches in accelerometer processing and statistical modeling to separate the osteogenic effects of frequency of short bouts of physical activity from total volume of physical activity. As such, the authors of this paper begin to explore in youth what animal models have shown for some time, that is, optimal bone adaptation requires the correct combination of intensity, frequency, duration, nonrepetitive movement, and rest. Together, these papers signal new and important approaches for the conceptualization, measurement, and interpretation of osteogenic physical activity. PMID- 29457755 TI - Novel approach for CES1 genotyping: integrating single nucleotide variants and structural variation. AB - AIM: Development of a specific procedure for genotyping of CES1A1 (CES1) and CES1A2, a hybrid of CES1A1 and the pseudogene CES1P1. MATERIALS & METHODS: The number of CES1A1 and CES1A2 copies and that of CES1P1 were determined using real-time PCR. Long range PCRs followed by secondary PCRs allowed sequencing of single nucleotide variants in CES1A1 and CES1A2. RESULTS & CONCLUSION: A procedure consisting of two main steps was developed. Its first main step, the copy number determination, informed about presence of CES1A2 . This information enabled choice of PCR in the second main step, which selectively amplified CES1A1 and, if present, also CES1A2, for subsequent sequencing. Examination of 501 DNA samples suggested that our procedure is specific with potential for personalization of drug treatments. PMID- 29457754 TI - Effect of ship hull form on the resistance penalty from biofouling. AB - Hull biofouling is a well-known problem for the shipping industry, leading to increased resistance and fuel consumption. Considering that the effects of hull form on resistance are known to be higher for a less slender hull, it is hypothesised in this paper that the effect of biofouling roughness on resistance is also dependent on the hull form. To test this hypothesis, previously reported full-scale numerical results on a containership are re-analysed. Form effects on roughness penalties, corresponding to KDeltaCT = 0.058 +/- 0.025, are observed at a low speed (19 knots, Res = 2.29 * 109), which are however cancelled out by traditionally neglected roughness effects on wave-making resistance at a higher speed (24 knots, Res = 2.89 * 109). It is concluded that hull form effects on biofouling penalties can be significant at low speeds, though not generalisable for higher speeds, namely when wave-making resistance corresponds to >= 29% of total resistance. PMID- 29457757 TI - Structural variability of DNA-containing Mg-pyrophosphate microparticles: optimized conditions to produce particles with desired size and morphology. AB - Our previous studies demonstrated the formation of structurally diverse DNA containing microparticles (DNA MPs) in PCR with Mg-pyrophosphate (MgPPi) as the structure-forming component. These DNA MPs were referred to major structural types: microdisks (2D MPs) with nanometer thickness and 3D MPs with sophisticated morphology and constructed from intersecting disks and their segments. Little is known about factors that influence both the morphology and size of DNA MPs, and the present study was aimed at fulfilling this gap. We showed that the addition of Mn2+ cations to PCR mixtures caused the profound changes in MPs morphology, depending on DNA polymerase used (KlenTaq or Taq). Asymmetric PCR with 20-fold decrease in the concentration of one of two primers facilitated the predominant formation of microdisks with unusual structure. The addition of 1 mM Na pyrophosphate to PCR mixtures with synthesized DNA and subsequent thermal cycling (10-15 cycles) were optimal to produce microdisks or nanometer 3D particles. Using electron microscopy, we studied also the structure of inorganic micro- and nanoparticles from MgPPi, formed during multiple heating and cooling cycles of a mixture of Mg2+ and Na-pyrophosphate in various regimes. Also, we found the conditions to yield planar (Mg.Mn)PPi nanocrystals (diameter ~100 nm and thickness ~10 nm) which efficiently adsorbed exogenous DNA. These inorganic nanoparticles are promising for DNA delivery in transfection studies. Mechanisms to be involved in structural modifications of MPs and perspectives of their practical application are discussed. PMID- 29457756 TI - Effects of combined oral contraceptives on the clinical and biochemical parameters of hyperandrogenism in patients with polycystic ovary syndrome: a systematic review and meta-analysis. AB - INTRODUCTION: Nowadays, selection of COCs with maximum antiandrogenic effects is one the main issues in treatment of women with polycystic ovary syndrome (PCOS). OBJECTIVE: This systematic review and meta-analysis aimed to compare the effects of COCs on the clinical and biochemical parameters of hyperandrogenism (HA) in patients with PCOS. METHODS: Electronic databases (PubMed, Scopus, ScienceDirect and web of science) were searched from 1987 to November 2015 to identify clinical trials investigating effect of the various COCs on the clinical and biochemical parameters of HA in patients. In this meta-analysis, both fixed and random effect models were used. Potential sources of heterogeneity were explored by meta regression and subgroup analyses. RESULTS: Findings showed that COC use for 3-12 months was significantly associated with an increase in sex hormone-binding globulin (SHBG) levels and a decrease in Ferriman-Gallwey (FG) score, total testosterone (TT), free testosterone (FT), androstenedione (A4) and dehydroepiandrosterone sulphate (DHEAS) levels. Type of progestin or duration of treatment had no important effects on declining androgen levels. Long-term use of COCs (6-12 months) was more effective in improving hirsutism, compared to short term. COCs containing cyproterone acetate (CPA) for 12 months had the strongest effect in improving hirsutism. CONCLUSIONS: This study shows that, in patients with PCOS, COCs can effectively improve biochemical and clinical parameters of HA. All COCs studies have similar effects on the hormonal profiles of these patients, and products containing CPA may be an effective treatment in hirsute patients with PCOS. PMID- 29457758 TI - Appraising cervical mucus: a new approach to evaluating contraceptives. AB - PURPOSE: Timing of sample collection represents a major source of variability in studies evaluating the effects of administered agents on cervical mucus in naturally-cycling women. We sought to create and validate an artificial model of the cervical mucus cycle using exogenous E2 and P4 replacement in ovarian suppressed women. MATERIALS AND METHODS: We conducted a prospective experiment (clinicaltrials.gov, NCT02969590) examining cervical mucus changes in six women during natural and artificial menstrual cycles [leuprolide acetate, estradiol transdermal patch (0.05-0.3 mg/day) and progesterone 200 mg/day]. We collected serum and mucus samples at each visit corresponding to early, mid and late follicular, ovulation and mid-luteal time points in the natural and artificial cycles. We evaluated mucus according to the modified Insler score described in the WHO laboratory Manual for the Examination and Processing of Human Semen. RESULTS: We enrolled healthy women between 27 and 40 years of age. All of the subjects achieved a mucus score of >=10 both in the natural cycle and during peak estradiol replacement levels (0.3 mg/day) in the artificial cycle. During the simulated luteal phase, all mucus scores were <=5 (median 3.5; range 1-5), similar to scores seen in the luteal phase of natural cycles (median 1; range 1 3). CONCLUSIONS: Our artificial cycle model (leuprolide acetate suppression) and dose escalation with estradiol patches produced favourable cervical mucus with mucus scores similar to those in the periovulatory phase of natural menstrual cycles. Additional studies are needed to validate the model for evaluation of mucus effects of contraceptive agents. PMID- 29457759 TI - ? PMID- 29457761 TI - Degradation of anti-inflammatory drugs in municipal wastewater by heterogeneous photocatalysis and electro-Fenton process. AB - Non-steroidal anti-inflammatory drugs (NSAID) are compounds frequently found in municipal wastewater and their degradation by conventional wastewater treatment plants (WWTP) is generally incomplete. This study compared the efficiency of two advanced oxidation processes (AOP), namely heterogeneous photocatalysis (HP) and electro-Fenton (EF), in the degradation of a mixture of common NSAID (diclofenac, ibuprofen and naproxen) dissolved in either deionized water or effluent from a WWTP. Both processes were effective in degrading the NSAID mixture and the trend of degradation was as follows, diclofenac > naproxen > ibuprofen. EF with a current density of 40 mA cm-2 and 0.3 mmol Fe2+ L-1 was the most efficient process to mineralize the organic compounds, achieving up to 92% TOC removal in deionized water and 90% in the WWTP effluent after 3 h of reaction. HP with 1.4 g TiO2 L-1 at pH 7 under sunlight, produced 85% TOC removal in deionized water and 39% in WWTP effluent also after 3 h treatment. The lower TOC removal efficiency shown by HP with the WWTP effluent was attributed mainly to the scavenging of reactive species by background organic matter in the wastewater. On the contrary, inorganic ions in the wastewater may produce oxidazing species during the EF process, which contributes to a higher degradation efficiency. EF is a promising option for the treatment of anti-inflammatory pharmaceuticals in municipal WWTP at competitive electrical energy efficiencies. PMID- 29457760 TI - A systematic review of serious games in medical education: quality of evidence and pedagogical strategy. AB - INTRODUCTION: The literature shows an optimistic landscape for the effectiveness of games in medical education. Nevertheless, games are not considered mainstream material in medical teaching. Two research questions that arise are the following: What pedagogical strategies do developers use when creating games for medical education? And what is the quality of the evidence on the effectiveness of games? METHODS: A systematic review was made by a multi-disciplinary team of researchers following the Cochrane Collaboration Guidelines. We included peer reviewed journal articles which described or assessed the use of serious games or gamified apps in medical education. We used the Medical Education Research Study Quality Instrument (MERSQI) to assess the quality of evidence in the use of games. We also evaluated the pedagogical perspectives of such articles. RESULTS: Even though game developers claim that games are useful pedagogical tools, the evidence on their effectiveness is moderate, as assessed by the MERSQI score. Behaviourism and cognitivism continue to be the predominant pedagogical strategies, and games are complementary devices that do not replace traditional medical teaching tools. Medical educators prefer simulations and quizzes focused on knowledge retention and skill development through repetition and do not demand the use of sophisticated games in their classrooms. Moreover, public access to medical games is limited. DISCUSSION: Our aim was to put the pedagogical strategy into dialogue with the evidence on the effectiveness of the use of medical games. This makes sense since the practical use of games depends on the quality of the evidence about their effectiveness. Moreover, recognition of said pedagogical strategy would allow game developers to design more robust games which would greatly contribute to the learning process.

PMID- 29457766 TI - Addressing Gaps in Mental Health and Addictions Nursing Leadership: An Innovative Professional Development Initiative. AB - Mental health and addictions services are integral to Canada's healthcare system, and yet it is difficult to recruit experienced nurse leaders with advanced practice, management or clinical informatics expertise in this field. Master's level graduates, aspiring to be mental health nurse leaders, often lack the confidence and experience required to lead quality improvement, advancements in clinical care, service design and technology innovations for improved patient care. This paper describes an initiative that develops nursing leaders through a unique scholarship, internship and mentorship model, which aims to foster confidence, critical thinking and leadership competency development in the mental health and addictions context. The "Mutual Benefits Model" framework was applied in the design and evaluation of the initiative. It outlines how mentee, mentor and organizational needs can drive strategic planning of resource investment, mentorship networks and relevant leadership competency-based learning plans to optimize outcomes. Five-year individual and organizational outcomes are described. PMID- 29457767 TI - Starting at the Beginning: The Role of Public Health Nursing in Promoting Infant and Early Childhood Mental Health. AB - The promotion, protection and restoration of mental health are foundational to healthy communities. However, most mental health services in Canada, already underfunded in comparison to hospital-based medical-surgical programs, continue to be focused on providing reactive acute care. Mental health problems in later life often have their roots in the prenatal, infancy and early childhood life periods, and considerable evidence has accumulated about the effectiveness of interventions during this period of time. Although public health nurses (PHNs) play a leadership role in Canada in developing and providing programs that promote mental health in the early years, much of this work is largely invisible. This paper describes the concept of infant and early childhood mental health, identifies key national policies, and explores the role of PHNs in supporting mental wellness for infants and families, in keeping with health equity and Indigenous perspectives. Canadian practice exemplars are provided to highlight the value of investing in the promotion of infant and early childhood mental health. PMID- 29457768 TI - Mending the Cracks: A Case Study in Using Technology to assist with Transitional Care for Persons with Dementia. AB - Transitions between hospital and community are particularly challenging for vulnerable adults experiencing behavioural and psychological symptoms (BPSD) of dementia. Too often, miscommunication results in triggering a recurrence of disruptive behaviours leading to frustration of staff and families. As part of the implementation of Health Quality Ontario (HQO) Quality Standards, this project involved improving transitions using an electronic-based care plan on a 23-bed geriatric dementia unit in a mental health hospital. "My Dementia Careplan," is an interprofessional care plan that was developed in the electronic medical record (EMR) to enhance communication of information between healthcare providers when patients are being discharged to the community. It is written from the patient's perspective in collaboration with the family and interprofessional team. It describes strategies to manage behavioural challenges along with the standardized tools to objectively monitor progress. This care planning will help to support transition of knowledge between hospital and community. PMID- 29457769 TI - Digital Mental Health - Innovations in Consumer Driven Care.

PMID- 29457770 TI - Lessons Learned After Losing my Brother to an Overdose: A Call to Action for Nurse Leaders. AB - The current overdose epidemic we are facing in Canada and internationally calls on nursing leaders to prioritize holistic and compassionate care for people who use drugs (PWUD) and their families. Nurses are well positioned to provide person centred care and advocate with and for this population. To do so requires an examination of one's personal values and beliefs surrounding drugs and the people who use them. As a nurse leader, I was forced to confront my views about illicit drug use following the untimely death of my brother Brad from overdose. This paper chronicles my personal experience with his death and subsequent journey into advocacy for drug policy reform amidst an emerging overdose crisis. This short paper is written from my personal perspective, and informed by both personal and professional experiences in drug policy reform. It addresses strategies for challenging stigma and opportunities for partnering with PWUD through engagement in harm reduction.

The forum provided the opportunity for interested community groups, members and individuals to share their experiences and to explore novel ways to prevent and respond to the substance abuse and addiction challenges in the region. Participants included community leaders, people and families living with addiction, service providers, local stakeholders, health professionals, researchers and Indigenous Elders. This paper describes the process and outcomes of this event and describes the role of nurse scholars in leading these efforts. PMID- 29457772 TI - Patient Partnership: One Organization's Journey. AB - Patient partnership has become a central element of healthcare delivery in many countries. The concept has specific relevance in mental health, as it is a critical enabler of recovery and healing (Bailey and Williams 2014). Patient partnership implies active engagement of patients in shaping decisions at the direct care, organizational and system level (Health Quality Ontario 2017). This article will outline the concept of patient partnership, and highlight the journey of one mental health. PMID- 29457773 TI - Optical waveguide and room temperature high-quality nanolasers from tin-catalyzed CdSSe nanostructures. AB - A simple two-step CVD method is developed to realize the growth of high-quality tin-catalyzed CdSSe alloy nanowires. Microstructural characterizations demonstrate that these wires are high-quality crystalline nanostructures. Local photoluminescence investigation of these nanostructures shows a typical band edge emission at 656 nm with a full-width at half-maximum of 22.3 nm. Optical waveguide measurement along an individual nanowire indicates that the output signal of the guided light has a rapid linear decrease accompanied with maximum red-shift about 109 meV after the transmission of 102 MUm. This obvious red-shift is caused by the intensive band-tail absorption during the optical transmission process. Moreover, optically pumped nanolasers are successfully realized at room temperature based on these unique wires, further demonstrating the achievement of stimulated emission from spontaneous emission, promoted by the pump power intensity. This work may find a simple route to the manufacture of superior nanowires for applications in waveguide and integrated photonic devices. PMID- 29457774 TI - A review of advances in pixel detectors for experiments with high rate and radiation. AB - The large Hadron collider (LHC) experiments ATLAS and CMS have established hybrid pixel detectors as the instrument of choice for particle tracking and vertexing in high rate and radiation environments, as they operate close to the LHC interaction points. With the high luminosity-LHC upgrade now in sight, for which the tracking detectors will be completely replaced, new generations of pixel detectors are being devised. They have to address enormous challenges in terms of data throughput and radiation levels, ionizing and non-ionizing, that harm the sensing and readout parts of pixel detectors alike. Advances in microelectronics and microprocessing technologies now enable large scale detector designs with unprecedented performance in measurement precision (space and time), radiation hard sensors and readout chips, hybridization techniques, lightweight supports, and fully monolithic approaches to meet these challenges. This paper reviews the world-wide effort on these developments. PMID- 29457775 TI - Mechanical properties of hollow and water-filled graphyne nanotube and carbon nanotube hybrid structure. AB - By performing molecular dynamics simulations, a GNT/CNT hybrid structure constructed via combing (6, 6) graphyne nanotube (GNT) with (6, 6) carbon nanotube (CNT) has been designed and investigated. The mechanical properties induced by the percentage of GNT, water content and electric field were examined. Calculation results reveal that the fracture strain and strength of hollow hybrid structure are remarkably smaller than that of perfect (6, 6) CNT. In addition, the Young's modulus decreases monotonously with the increase of percentage of GNT. More importantly, the tunable mechanical properties of hybrid structure can be achieved through filling with water molecules and applying an electric field along tensile direction. Specifically, increasing water content from 0.0 to 8.70 mmol g-1 in the absence of electric field could result in fracture strain and strength reducing by 15.09% and 12.87%, respectively. Besides, enhancing fracture strain and strength of water-filled hybrid structure with water content of 8.70 mmol g-1 can also be obtained with rising electric field intensity. These findings would provide a valuable theoretical basis for designing and fabricating a nanodevice with controllable mechanical performances. PMID- 29457776 TI - Free-anchored Nb2O5@graphene networks for ultrafast-stable lithium storage. AB - Orthorhombic Nb2O5 (T-Nb2O5) has structural merit but poor electrical conductivity, limiting their applications in energy storage. Although graphene is frequently adopted to effectively improve its electrochemical properties, the ordinary modified methods cannot meet the growing demands for high-performance. Here, we demonstrate that different graphene modified routes play a vital role in affecting the electrochemical performances of T-Nb2O5. By only manual shaking within one minute, Nb2O5 nano-particles can be rapidly adsorbed onto graphene, then the free-anchored T-Nb2O5@graphene three-dimensional networks can be successfully prepared based on hydrogel method. As for the application in lithium ion batteries, it performs outstanding rate character (129 mA h g-1 (25C rate), 110 mA h g-1 (50C rate) and 90 mA h g-1 (100C rate), correspond to 79%, 67% and 55% capacity of 0.5C rate, respectively) and excellent long-term cycling feature (~70% capacity retention after 20000 cycles). Moreover, it still maintains similar ultrafast-stable lithium storage performances when Cu foil is substituted by Al foil as current collector. In addition, relevant kinetics mechanisms are also expounded. This work provides a versatile strategy for the preparation of graphene modified Nb2O5 or other types of nanoparticles. PMID- 29457777 TI - Perfect-absorption graphene metamaterials for surface-enhanced molecular fingerprint spectroscopy. AB - Graphene plasmon with extremely strong light confinement and tunable resonance frequency represents a promising surface-enhanced infrared absorption (SEIRA) sensing platform. However, plasmonic absorption is relatively weak (approximately 1%-9%) in monolayer graphene nanostructures, which would limit its sensitivity. Here, we theoretically propose a hybrid plasmon-metamaterial structure that can realize perfect absorption in graphene with a low carrier mobility of 1000 cm2 V 1 s-1. This structure combines a gold reflector and a gold grating to the graphene plasmon structures, which introduce interference effect and the lightning-rod effect, respectively, and largely enhance the coupling of light to graphene. The vibration signal of trace molecules can be enhanced up to 2000-fold at the hotspot of the perfect-absorption structure, enabling the SEIRA sensing to reach the molecular level. This hybrid metal-graphene structure provides a novel path to generate high sensitivity in nanoscale molecular recognition for numerous applications. PMID- 29457778 TI - Theoretical investigation of performance of armchair graphene nanoribbon field effect transistors. AB - In this paper, we theoretically investigate the highest possible expected performance for graphene nanoribbon field effect transistors (GNRFETs) for a wide range of operation voltages and device structure parameters, such as the width of the graphene nanoribbon and gate length. We formulated a self-consistent, non equilibrium Green's function method in conjunction with the Poisson equation and modeled the operation of nanometer sized GNRFETs, of which GNR channels have finite bandgaps so that the GNRFET can operate as a switch. We propose a metric for competing with the current silicon CMOS high performance or low power devices and explain that this can vary greatly depending on the GNRFET structure parameters. PMID- 29457779 TI - Embedding ultrafine ZnSnO3 nanoparticles into reduced graphene oxide composites as high-performance electrodes for lithium ion batteries. AB - Ultrafine ZnSnO3 nanoparticles, with an average diameter of 45 nm, homogeneously grown on reduced graphene oxide (rGO) have been successfully fabricated via methods of low temperature coprecipitation, colloid electrostatic self-assembly, and hydrothermal treatment. The uniformly distributed ZnSnO3 nanocrystals could inhibit the restacking of rGO sheets. In turn, the existence of rGO could hinder the growth and aggregation of ZnSnO3 nanoparticles in the synthesis process, increase the conductivity of the composite, and buffer the volume expansion of the ZnSnO3 nanocrystals upon lithium ion insertion and extraction. The obtained ZnSnO3/rGO exhibited superior cycling stability with a discharge/charge capacity of 718/696 mA h g-1 after 100 cycles at a current density of 0.1 A g-1.

PMID- 29457781 TI - Efficient synthesis of tungsten oxide hydrate-based nanocomposites for applications in bifunctional electrochromic-energy storage devices. AB - In this work, we realized the large-scale synthesis of WO3 . H2O nanoflakes (NFs), g-C3N4/WO3 . H2O nanocomposite (NC) and graphene (G)/WO3 . H2O NC via a sonochemical process with tungsten salt as the precursor, g-C3N4 or G sheets as the supports, and distilled water as the solvent. Both the g-C3N4/WO3 . H2O NC and G/WO3 . H2O NC exhibited much better electrochromic (EC) performance (higher coloration efficiencies and faster response times) than that of the WO3 . H2O NFs. Using the WO3 . H2O-based materials as electrode materials, EC batteries that integrate the energy storage and EC functions in one device have been assembled. The energy status of the EC batteries could be visually indicated by the reversible color variations. Compared with the plain WO3 . H2O-based EC batteries, the NC-based EC batteries possessed a lower color contrast between the charged and discharged conditions but much longer discharge durations. The EC batteries could be quickly charged in a few seconds by adding H2O2, and the charged batteries exhibited significantly-enhanced discharging durations in comparison with the initial ones. The g-C3N4/WO3 . H2O NC-EC batteries charged by a small amount of H2O2 could produce a long discharging duration up to 760 min. PMID- 29457782 TI - Hypothalamic ER-associated degradation regulates POMC maturation, feeding, and age-associated obesity. AB - Pro-opiomelanocortin (POMC) neurons function as key regulators of metabolism and physiology by releasing prohormone-derived neuropeptides with distinct biological activities. However, our understanding of early events in prohormone maturation in the ER remains incomplete. Highlighting the significance of this gap in knowledge, a single POMC cysteine-to-phenylalanine mutation at position 28 (POMC C28F) is defective for ER processing and causes early onset obesity in a dominant negative manner in humans through an unclear mechanism. Here, we report a pathologically important role of Sel1L-Hrd1, the protein complex of ER-associated degradation (ERAD), within POMC neurons. Mice with POMC neuron-specific Sel1L deficiency developed age-associated obesity due, at least in part, to the ER retention of POMC that led to hyperphagia. The Sel1L-Hrd1 complex targets a fraction of nascent POMC molecules for ubiquitination and proteasomal degradation, preventing accumulation of misfolded and aggregated POMC, thereby ensuring that another fraction of POMC can undergo normal posttranslational processing and trafficking for secretion. Moreover, we found that the disease associated POMC-C28F mutant evades ERAD and becomes aggregated due to the presence of a highly reactive unpaired cysteine thiol at position 50. Thus, this study not only identifies ERAD as an important mechanism regulating POMC maturation within the ER, but also provides insights into the pathogenesis of monogenic obesity associated with defective prohormone folding. PMID- 29457783 TI - Cellular senescence in brain aging and neurodegenerative diseases: evidence and perspectives. AB - Along with a general decline in overall health, most chronic degenerative human diseases are inherently associated with increasing age. Age-associated cognitive impairments and neurodegenerative diseases, such as Parkinson's and Alzheimer's diseases, are potentially debilitating conditions that lack viable options for treatment, resulting in a tremendous economic and societal cost. Most high profile clinical trials for neurodegenerative diseases have led to inefficacious results, suggesting that novel approaches to treating these pathologies are needed. Numerous recent studies have demonstrated that senescent cells, which are characterized by sustained cell cycle arrest and production of a distinct senescence-associated secretory phenotype, accumulate with age and at sites of age-related diseases throughout the body, where they actively promote tissue deterioration. Cells with features of senescence have been detected in the context of brain aging and neurodegenerative disease, suggesting that they may also promote dysfunction. Here, we discuss the evidence implicating senescent cells in neurodegenerative diseases, the mechanistic contribution of these cells that may actively drive neurodegeneration, and how these cells or their effects may be targeted therapeutically. PMID- 29457784 TI - HIV latency is reversed by ACSS2-driven histone crotonylation. AB - Eradication of HIV-1 (HIV) is hindered by stable viral reservoirs. Viral latency is epigenetically regulated. While the effects of histone acetylation and methylation at the HIV long-terminal repeat (LTR) have been described, our knowledge of the proviral epigenetic landscape is incomplete. We report that a previously unrecognized epigenetic modification of the HIV LTR, histone crotonylation, is a regulator of HIV latency. Reactivation of latent HIV was achieved following the induction of histone crotonylation through increased expression of the crotonyl-CoA-producing enzyme acyl-CoA synthetase short-chain family member 2 (ACSS2). This reprogrammed the local chromatin at the HIV LTR through increased histone acetylation and reduced histone methylation. Pharmacologic inhibition or siRNA knockdown of ACSS2 diminished histone crotonylation-induced HIV replication and reactivation. ACSS2 induction was highly synergistic in combination with either a protein kinase C agonist (PEP005) or a histone deacetylase inhibitor (vorinostat) in reactivating latent HIV. In the SIV-infected nonhuman primate model of AIDS, the expression of ACSS2 was significantly induced in intestinal mucosa in vivo, which correlated with altered fatty acid metabolism. Our study links the HIV/SIV infection-induced fatty acid enzyme ACSS2 to HIV latency and identifies histone lysine crotonylation as a novel epigenetic regulator for HIV transcription that can be targeted for HIV eradication. PMID- 29457785 TI - TIA1 variant drives myodegeneration in multisystem proteinopathy with SQSTM1 mutations. AB - Multisystem proteinopathy (MSP) involves disturbances of stress granule (SG) dynamics and autophagic protein degradation that underlie the pathogenesis of a spectrum of degenerative diseases that affect muscle, brain, and bone. Specifically, identical mutations in the autophagic adaptor SQSTM1 can cause varied penetrance of 4 distinct phenotypes: amyotrophic lateral sclerosis (ALS), frontotemporal dementia, Paget's disease of the bone, and distal myopathy. It has been hypothesized that clinical pleiotropy relates to additional genetic determinants, but thus far, evidence has been lacking. Here, we provide evidence that a TIA1 (p.N357S) variant dictates a myodegenerative phenotype when inherited, along with a pathogenic SQSTM1 mutation. Experimentally, the TIA1 N357S variant significantly enhances liquid-liquid-phase separation in vitro and impairs SG dynamics in living cells. Depletion of SQSTM1 or the introduction of a mutant version of SQSTM1 similarly impairs SG dynamics. TIA1-N357S-persistent SGs have increased association with SQSTM1, accumulation of ubiquitin conjugates, and additional aggregated proteins. Synergistic expression of the TIA1-N357S variant and a SQSTM1-A390X mutation in myoblasts leads to impaired SG clearance and myotoxicity relative to control myoblasts. These findings demonstrate a pathogenic connection between SG homeostasis and ubiquitin-mediated autophagic degradation that drives the penetrance of an MSP phenotype. PMID- 29457787 TI - Alternative macrophages in atherosclerosis: not always protective! AB - Atherosclerosis is a chronic inflammatory disease of the vasculature that is initiated by cholesterol deposition into the arterial wall, which triggers the infiltration of immune and inflammatory cells, including monocytes and macrophages. As atherosclerotic plaques progress, localized hypoxia promotes compensatory angiogenesis from the vasa vasorum. Immature neovessels are prone to leakage, thus destabilizing the plaque and leading to intraplaque hemorrhage. Macrophages with different phenotypes, ranging from classical inflammatory subtypes to alternatively activated antiinflammatory macrophages, have been identified in atherosclerotic lesions. Antiinflammatory hemoglobin-scavenging CD163+ macrophages are present in neovessel- and hemorrhage-rich areas; however, the role of these macrophages in atherogenesis has been unclear. In this issue of the JCI, Guo, Akahori, and colleagues show that CD163+ macrophages promote angiogenesis, vessel permeability, and leucocyte infiltration in human and mouse atherosclerotic lesions through a mechanism involving hemoglobin:haptoglobin/CD163/HIF1alpha-mediated VEGF induction. This study thus identifies proatherogenic properties of CD163+ macrophages, which previously were thought to be beneficial. PMID- 29457786 TI - Intracellular lipid metabolism impairs beta cell compensation during diet-induced obesity. AB - The compensatory proliferation of insulin-producing beta cells is critical to maintaining glucose homeostasis at the early stage of type 2 diabetes. Failure of beta cells to proliferate results in hyperglycemia and insulin dependence in patients. To understand the effect of the interplay between beta cell compensation and lipid metabolism upon obesity and peripheral insulin resistance, we eliminated LDL receptor-related protein 1 (LRP1), a pleiotropic mediator of cholesterol, insulin, energy metabolism, and other cellular processes, in beta cells. Upon high-fat diet exposure, LRP1 ablation significantly impaired insulin secretion and proliferation of beta cells. The diminished insulin signaling was partly contributed to by the hypersensitivity to glucose-induced, Ca2+-dependent activation of Erk and the mTORC1 effector p85 S6K1. Surprisingly, in LRP1 deficient islets, lipotoxic sphingolipids were mitigated by improved lipid metabolism, mediated at least in part by the master transcriptional regulator PPARgamma2. Acute overexpression of PPARgamma2 in beta cells impaired insulin signaling and insulin secretion. Elimination of Apbb2, a functional regulator of LRP1 cytoplasmic domain, also impaired beta cell function in a similar fashion. In summary, our results uncover the double-edged effects of intracellular lipid metabolism on beta cell function and viability in obesity and type 2 diabetes and highlight LRP1 as an essential regulator of these processes. PMID- 29457788 TI - SCN5A: the greatest HITS collection. AB - Heart failure (HF) has been referred to as the cardiovascular epidemic of our time. Understanding the molecular determinants of HF disease progression and mortality risk is of utmost importance. In this issue of the JCI, Zhang et al. uncover an important link between clinical HF mortality risk and a common variant that regulates SCN5A expression through microRNA-dependent (miR dependent)mechanisms. They also demonstrate that haploinsufficiency of SCN5A is associated with increased accumulation of reactive oxygen species (ROS) in a genetically engineered murine model. Their data suggest that even modest depression of SCN5A expression may promote pathologic cardiac remodeling and progression of HF. PMID- 29457789 TI - A common variant alters SCN5A-miR-24 interaction and associates with heart failure mortality. AB - SCN5A encodes the voltage-gated Na+ channel NaV1.5 that is responsible for depolarization of the cardiac action potential and rapid intercellular conduction. Mutations disrupting the SCN5A coding sequence cause inherited arrhythmias and cardiomyopathy, and single-nucleotide polymorphisms (SNPs) linked to SCN5A splicing, localization, and function associate with heart failure related sudden cardiac death. However, the clinical relevance of SNPs that modulate SCN5A expression levels remains understudied. We recently generated a transcriptome-wide map of microRNA (miR) binding sites in human heart, evaluated their overlap with common SNPs, and identified a synonymous SNP (rs1805126) adjacent to a miR-24 site within the SCN5A coding sequence. This SNP was previously shown to reproducibly associate with cardiac electrophysiological parameters, but was not considered to be causal. Here, we show that miR-24 potently suppresses SCN5A expression and that rs1805126 modulates this regulation. We found that the rs1805126 minor allele associates with decreased cardiac SCN5A expression and that heart failure subjects homozygous for the minor allele have decreased ejection fraction and increased mortality, but not increased ventricular tachyarrhythmias. In mice, we identified a potential basis for this in discovering that decreased Scn5a expression leads to accumulation of myocardial reactive oxygen species. Together, these data reiterate the importance of considering the mechanistic significance of synonymous SNPs as they relate to miRs and disease, and highlight a surprising link between SCN5A expression and nonarrhythmic death in heart failure.

AB - Super-resolution microscopy depends on steps that can contribute to the formation of image artifacts, leading to misinterpretation of biological information. We present NanoJ-SQUIRREL, an ImageJ-based analytical approach that provides quantitative assessment of super-resolution image quality. By comparing diffraction-limited images and super-resolution equivalents of the same acquisition volume, this approach generates a quantitative map of super resolution defects and can guide researchers in optimizing imaging parameters. PMID- 29457792 TI - On the design of CRISPR-based single-cell molecular screens. AB - Several groups recently coupled CRISPR perturbations and single-cell RNA-seq for pooled genetic screens. We demonstrate that vector designs of these studies are susceptible to ~50% swapping of guide RNA-barcode associations because of lentiviral template switching. We optimized a published alternative, CROP-seq, in which the guide RNA also serves as the barcode, and here confirm that this strategy performs robustly and doubled the rate at which guides are assigned to cells to 94%. PMID- 29457790 TI - CD163+ macrophages promote angiogenesis and vascular permeability accompanied by inflammation in atherosclerosis. AB - Intake of hemoglobin by the hemoglobin-haptoglobin receptor CD163 leads to a distinct alternative non-foam cell antiinflammatory macrophage phenotype that was previously considered atheroprotective. Here, we reveal an unexpected but important pathogenic role for these macrophages in atherosclerosis. Using human atherosclerotic samples, cultured cells, and a mouse model of advanced atherosclerosis, we investigated the role of intraplaque hemorrhage on macrophage function with respect to angiogenesis, vascular permeability, inflammation, and plaque progression. In human atherosclerotic lesions, CD163+ macrophages were associated with plaque progression, microvascularity, and a high level of HIF1alpha and VEGF-A expression. We observed irregular vascular endothelial cadherin in intraplaque microvessels surrounded by CD163+ macrophages. Within these cells, activation of HIF1alpha via inhibition of prolyl hydroxylases promoted VEGF-mediated increases in intraplaque angiogenesis, vascular permeability, and inflammatory cell recruitment. CD163+ macrophages increased intraplaque endothelial VCAM expression and plaque inflammation. Subjects with homozygous minor alleles of the SNP rs7136716 had elevated microvessel density, increased expression of CD163 in ruptured coronary plaques, and a higher risk of myocardial infarction and coronary heart disease in population cohorts. Thus, our findings highlight a nonlipid-driven mechanism by which alternative macrophages promote plaque angiogenesis, leakiness, inflammation, and progression via the CD163/HIF1alpha/VEGF-A pathway. PMID- 29457793 TI - Identifying the favored mutation in a positive selective sweep. AB - Most approaches that capture signatures of selective sweeps in population genomics data do not identify the specific mutation favored by selection. We present iSAFE (for "integrated selection of allele favored by evolution"), a method that enables researchers to accurately pinpoint the favored mutation in a large region (~5 Mbp) by using a statistic derived solely from population genetics signals. iSAFE does not require knowledge of demography, the phenotype under selection, or functional annotations of mutations. PMID- 29457794 TI - Recon3D enables a three-dimensional view of gene variation in human metabolism. AB - Genome-scale network reconstructions have helped uncover the molecular basis of metabolism. Here we present Recon3D, a computational resource that includes three dimensional (3D) metabolite and protein structure data and enables integrated analyses of metabolic functions in humans. We use Recon3D to functionally characterize mutations associated with disease, and identify metabolic response signatures that are caused by exposure to certain drugs. Recon3D represents the most comprehensive human metabolic network model to date, accounting for 3,288 open reading frames (representing 17% of functionally annotated human genes), 13,543 metabolic reactions involving 4,140 unique metabolites, and 12,890 protein structures. These data provide a unique resource for investigating molecular mechanisms of human metabolism. Recon3D is available at http://vmh.life. PMID- 29457795 TI - Random access in large-scale DNA data storage. AB - Synthetic DNA is durable and can encode digital data with high density, making it an attractive medium for data storage. However, recovering stored data on a large scale currently requires all the DNA in a pool to be sequenced, even if only a subset of the information needs to be extracted. Here, we encode and store 35 distinct files (over 200 MB of data), in more than 13 million DNA oligonucleotides, and show that we can recover each file individually and with no errors, using a random access approach. We design and validate a large library of primers that enable individual recovery of all files stored within the DNA. We also develop an algorithm that greatly reduces the sequencing read coverage required for error-free decoding by maximizing information from all sequence reads. These advances demonstrate a viable, large-scale system for DNA data storage and retrieval.

PMID- 29457796 TI - H3B-8800, an orally available small-molecule splicing modulator, induces lethality in spliceosome-mutant cancers. AB - Genomic analyses of cancer have identified recurrent point mutations in the RNA splicing factor-encoding genes SF3B1, U2AF1, and SRSF2 that confer an alteration of function. Cancer cells bearing these mutations are preferentially dependent on wild-type (WT) spliceosome function, but clinically relevant means to therapeutically target the spliceosome do not currently exist. Here we describe an orally available modulator of the SF3b complex, H3B-8800, which potently and preferentially kills spliceosome-mutant epithelial and hematologic tumor cells. These killing effects of H3B-8800 are due to its direct interaction with the SF3b complex, as evidenced by loss of H3B-8800 activity in drug-resistant cells bearing mutations in genes encoding SF3b components. Although H3B-8800 modulates WT and mutant spliceosome activity, the preferential killing of spliceosome mutant cells is due to retention of short, GC-rich introns, which are enriched for genes encoding spliceosome components. These data demonstrate the therapeutic potential of splicing modulation in spliceosome-mutant cancers.

PMID- 29457801 TI - Time Domain and Frequency Domain Deterministic Channel Modeling for Tunnel/Mining Environments. AB - Understanding wireless channels in complex mining environments is critical for designing optimized wireless systems operated in these environments. In this paper, we propose two physics-based, deterministic ultra-wideband (UWB) channel models for characterizing wireless channels in mining/tunnel environments - one in the time domain and the other in the frequency domain. For the time domain model, a general Channel Impulse Response (CIR) is derived and the result is expressed in the classic UWB tapped delay line model. The derived time domain channel model takes into account major propagation controlling factors including tunnel or entry dimensions, frequency, polarization, electrical properties of the four tunnel walls, and transmitter and receiver locations. For the frequency domain model, a complex channel transfer function is derived analytically. Based on the proposed physics-based deterministic channel models, channel parameters such as delay spread, multipath component number, and angular spread are analyzed. It is found that, despite the presence of heavy multipath, both channel delay spread and angular spread for tunnel environments are relatively smaller compared to that of typical indoor environments. The results and findings in this paper have application in the design and deployment of wireless systems in underground mining environments.

AB - This paper introduces the design, calibration, and validation of a low-cost portable sensor for the real-time measurement of dust particles within the environment. The proposed design consists of low hardware cost and calibration based on temperature and humidity sensing to achieve accurate processing of airborne dust density. Using commercial particulate matter sensors, a highly accurate air quality monitoring sensor was designed and calibrated using real world variations in humidity and temperature for indoor and outdoor applications. Furthermore, to provide a low-cost secure solution for real-time data transfer and monitoring, an onboard Bluetooth module with AES data encryption protocol was implemented. The wireless sensor was tested against a Dylos DC1100 Pro Air Quality Monitor, as well as an Alphasense OPC-N2 optical air quality monitoring sensor for accuracy. The sensor was also tested for reliability by comparing the sensor to an exact copy of itself under indoor and outdoor conditions. It was found that accurate measurements under real-world humid and temperature varying and dynamically changing conditions were achievable using the proposed sensor when compared to the commercially available sensors. In addition to accurate and reliable sensing, this sensor was designed to be wearable and perform real-time data collection and transmission, making it easy to collect and analyze data for air quality monitoring and real-time feedback in remote health monitoring applications. Thus, the proposed device achieves high quality measurements at lower-cost solutions than commercially available wireless sensors for air quality.

AB - Estrogens are biologically active steroid hormones mainly released from the ovary by ovarian secretion of estrogen into the circulating blood to regulate or function at the distal target. Estrogens play an important role in the central nervous system, cardiovascular system and immune system, especially for post menopausal women. Panax ginseng Mayer has been reported to relieve women's menopausal symptoms and affect estrogen activities. However, the mechanism of its estrogen regulation has not yet been clearly investigated. In this work, ovariectomized rats were administered a P. ginseng decoction intragastrically for 8 weeks. Urine samples were analyzed by ultra performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS) to identify metabolites. The estrous cycle, body weight, uterine weight index and serum hormone levels were measured. The results showed that P. ginseng significantly prolonged the estrus stage, decreased the body weight and serum luteinizing hormone (LH) levels and increased the uterine weight index and serum estradiol (E2) levels of ovariectomized rats. A total of twelve potential biomarkers for which levels changed markedly upon treatment have been identified based on metabolomics. A systematic network analysis of their corresponding pathways indicates that the antagonistic effect of P. ginseng on ovariectomized rats occurs mainly through regulating steroid hormone metabolism, fatty acid biosynthesis, the citric acid cycle and tryptophan metabolism. In conclusion, this study validated the antagonistic effect of P. ginseng in rats with estrogen decline and explored the metabolic and biochemical mechanisms involved. PMID- 29457806 TI - Enhancement of the selectivity of MXenes (M2C, M = Ti, V, Nb, Mo) via oxygen functionalization: promising materials for gas-sensing and -separation. AB - Two-dimensional graphene-like materials, namely MXenes, have been proposed as potential materials for various applications. In this work, the reactivity and selectivity of four MXenes (i.e. M2C (M = Ti, V, Nb, Mo)) and their oxygen functionalized forms (i.e. O-MXenes or M2CO2) toward gas molecules were investigated by using the plane wave-based Density Functional Theory (DFT) calculations. Small gas molecules, which are commonly found in flue gas streams, are considered herein. Our results demonstrated that MXenes are very reactive. Chemisorption is a predominant process for gas adsorption on MXenes. Simultaneously dissociative adsorption can be observed in most cases. The high reactivity of their non-functionalized surface is attractive for catalytic applications. In contrast, their reactivity is reduced, but the selectivity is improved upon oxygen functionalization. Mo2CO2 and V2CO2 present good selectivity toward NO molecules, while Nb2CO2 and Ti2CO2 show good selectivity toward NH3. The electronic charge properties explain the nature of the substrates and also interactions between them and the adsorbed gases. Our results indicated that O MXenes are potential materials for gas-separation/capture, -storage, -sensing, etc. Furthermore, their structural stability and SO2-tolerant nature are attractive properties for using them in a wide range of applications. Our finding provides good information to narrow down the choices of materials to be tested in future experimental work.

AB - The heteroleptic complexes [Cu(tBu-xantphos)(bpy)][PF6] and [Ag(tBu xantphos)(bpy)][PF6], where tBu-xantphos = 9,9-dimethyl-4,5-bis(di-tert butylphosphino)xanthene and bpy = 2,2'-bipyridine have been synthesized and their photophysical properties investigated. Single crystal X-ray diffraction studies of the compounds under ambient and increased pressure are presented; increase in pressure results in little structural perturbation. For the copper(i) complexes, the effects of changing the N^N ligand from bpy to 6-methyl-2,2'-bipyridine (6 Mebpy), 6-bromo-2,2'-bipyridine (6-Brbpy), and 4,4'-di(tert-butyl)-2,2' bipyridine (4,4'-tBu2bpy) were also investigated. Emissions from the copper(i) complexes are weak, both in solution and the solid state and this is attributed to vibrational quenching effects of the tert-butyl substituents of the tBu xantphos ligands.

AB - Semiconductor nanostructures have received considerable attention in the field of photocatalytic hydrogen evolution. However, eco-friendly, high efficiency, and low-cost semiconductor materials are still desired. In consideration of this, herein, we design a new and economic noble-metal-free CdS/ZnxCo3-xO4 (CdS/ZCO) nanohybrid photocatalyst using a metal-organic framework (MOF) template, which is a framework structure composed of organic ligands and metal ion nodes with different numbers of connections. The as-prepared CdS/ZCO composites with a large specific surface area and porous hollow structure exhibit remarkable catalytic activity and high stability for hydrogen generation. The hydrogen evolution rate is about 3978.6 MUmol g-1 h-1 with lactic acid as the sacrificial agent when the optimized amount of CdS nanoparticles (30 wt%) is decorated on the ZCO frame, and the production efficiency of H2 for CdS/ZCO is 4 times higher than that for CdS nanospheres or CdS/Co3O4. The significantly enhanced photocatalytic activity of CdS/ZCO is attributed to the efficient charge separation and transfer between the phase boundary of CdS and ZCO. In addition, the composites exhibit better hydrogen production in lactic acid than in methanol, and the remarkable catalytic activity and high stability of the CdS/ZCO composites for hydrogen evolution indicate that MOF-based composite materials have potential application prospects in energy conversion.

AB - In lipid monolayers with phase coexistence, domains of the liquid-condensed phase always present size polydispersity. However, very few theoretical works consider size distribution effects on the monolayer properties. Because of the difference in surface densities, domains have excess dipolar density with respect to the surrounding liquid expanded phase, originating a dipolar inter-domain interaction. This interaction depends on the domain area, and hence the presence of a domain size distribution is associated with interaction polydispersity. Inter-domain interactions are fundamental to understanding the structure and dynamics of the monolayer. For this reason, it is expected that polydispersity significantly alters monolayer properties. By means of Brownian dynamics simulations, we study the radial distribution function (RDF), the average mean square displacement and the average time-dependent self-diffusion coefficient, D(t), of lipid monolayers with normally distributed size domains. For this purpose, we vary the relevant system parameters, polydispersity and interaction strength, within a range of experimental interest. We also analyze the consequences of using a monodisperse model to determine the interaction strength from an experimental RDF. We find that polydispersity strongly affects the value of the interaction strength, which is greatly underestimated if polydispersity is not considered. However, within a certain range of parameters, the RDF obtained from a polydisperse model can be well approximated by that of a monodisperse model, by suitably fitting the interaction strength, even for 40% polydispersities. For small interaction strengths or small polydispersities, the polydisperse systems obtained from fitting the experimental RDF have an average mean square displacement and D(t) in good agreement with that of the monodisperse system.

AB - The aerobic epoxidation of propylene over the metal-organic framework Fe3(btc)2 (btc = 1,3,5-benzentricarboxylate) as catalyst has been investigated by means of density functional calculations. The mechanisms of the reaction towards propylene oxide, carbonylic products (acetone and propanal) and a pi-allyl radical were investigated to assess the efficiency of Fe3(btc)2 for the selective formation of propylene oxide. Propylene oxide and carbonylic products are formed on Fe3(btc)2 by proceeding via propyleneoxy intermediates in the first step. Subsequently, the intermediates can then either be transformed to propylene oxide by way of ring closure of the intermediate or to the carbonylic compounds of propanal and acetone via 1,2-hydride shift. The results show that the formation of propylene oxide is favored over the formation of carbonylic products mainly due to the activation barriers being 2-3 times smaller. The activation barriers for the formation of the propyleneoxy intermediates on the Fe3(btc)2 catalyst for the first and second reaction cycle are also lower than the barriers obtained for the formation of the pi-allyl radical that acts as the precursor to combustion products. On the basis of these computational results, we therefore expect a high catalytic selectivity of the Fe3(btc)2 catalyst with respect to the formation of propylene oxide. We also compared the catalytic activities of Fe3(btc)2 and Cu3(btc)2. The activation energy of the rate-determining step is almost 2 times lower for Fe3(btc)2 than that for Cu3(btc)2, due to a larger charge transfer from the catalytic site to the O2 molecule in the case of Fe3(btc)2.

AB - Synthetic LAPONITE(r)-clay particles with platelet-like shape display strong aging when dispersed in aqueous solutions, preventing the latter from reaching their natural liquid-crystalline equilibrium state. Here we introduce a facile method that successfully prevents this aging behaviour and enables accessing the systems' liquid-crystal and crystalline phases. We graft the comb-like polymer PLL-PEG (poly(l-lysine)-g-poly(ethylene glycol)) onto the clay surfaces from solution, thereby screening the negative surface charges and thus ensuring steric stabilisation. We show zeta-sizer and rheology measurements, respectively, confirming complete steric coating and that aging of dilute samples is completely suppressed even after a year. Using evaporation as a means to concentrate the particles, we observe various liquid crystalline textures under a polarized optical microscope (POM). Upon sequential spreading and drying, we are also able to obtain transparent films with hierarchical architecture. PMID- 29457812 TI - Diffusive interaction of multiple surface nanobubbles: shrinkage, growth, and coarsening. AB - Surface nanobubbles are nanoscopic spherical-cap shaped gaseous domains on immersed substrates which are stable, even for days. After the stability of a single surface nanobubble has been theoretically explained, i.e. contact line pinning and gas oversaturation are required to stabilize it against diffusive dissolution [Lohse and Zhang, Phys. Rev. E, 2015, 91, 031003(R)], here we focus on the collective diffusive interaction of multiple nanobubbles. For that purpose we develop a finite difference scheme for the diffusion equation with the appropriate boundary conditions and with the immersed boundary method used to represent the growing or shrinking bubbles. After validation of the scheme against the exact results of Epstein and Plesset for a bulk bubble [J. Chem. Phys., 1950, 18, 1505] and of Lohse and Zhang for a surface bubble, the framework of these simulations is used to describe the coarsening process of competitively growing nanobubbles. The coarsening process for such diffusively interacting nanobubbles slows down with advancing time and increasing bubble distance. The present results for surface nanobubbles are also applicable for immersed surface nanodroplets, for which better controlled experimental results of the coarsening process exist.

PMID- 29457815 TI - Hydrogen bonding effect between active site and protein environment on catalysis performance in H2-producing [NiFe] hydrogenases. AB - The interaction between the active site and the surrounding protein environment plays a fundamental role in the hydrogen evolution reaction (HER) in [NiFe] hydrogenases. Our density functional theory (DFT) findings demonstrate that the reaction Gibbs free energy required for the rate determining step decreases by 7.1 kcal mol-1 when the surrounding protein environment is taken into account, which is chiefly due to free energy decreases for the two H+/e- addition steps (the so-called Ni-SIa to I1, and Ni-C to Ni-R), being the largest thermodynamic impediments of the whole reaction. The variety of hydrogen bonds (H-bonds) between the amino acids and the active site is hypothesised to be the main reason for such stability: H-bonds not only work as electrostatic attractive forces that influence the charge redistribution, but more importantly, they act as an electron 'pull' taking electrons from the active site towards the amino acids. Moreover, the electron 'pull' effect through H-bonds via the S- in cysteine residues shows a larger influence on the energy profile than that via the CN- ligands on Fe.

PMID- 29457824 TI - Understanding the conformational analysis of gababutin based hybrid peptides. AB - Constrained gamma-amino acid gababutin (Gbn) based peptides that form different conformations have been synthesized. Striving to rationalize the impact of side chain orientations framing tetrapeptide-based supramolecular organic frameworks and morphological entities, Gbn incorporated hybrid peptides Boc-Gbn-Aib-Aaa-Aib OMe (where Aaa = Phe(F) for peptide 1, Leu(L) for peptide 2 and Tyr(Y) for peptide 3) were synthesized by changing the amino acid at the third position. The solution state dual folded conformation (C12/C10 H-bonded) is probed by 2D NMR spectroscopy in support of a DMSO-d6 titration and VT NMR experiments. Peptides 1 3 adopt a C12/C10 type H-bonded dual folded conformation in the crystal state. In addition, distinct supramolecular frameworks result from the modification and orientation of the third residue side chain of peptides 1-3. A solvent induced morphological diversity of peptides 1-3 is attained by modifying the side chain backbone of the tetrapeptides, which are investigated by various microscopic (SEM and AFM) studies. Gbn-based peptides 1-3 show significant morphological and supramolecular packing properties, which are fairly different from those of their gabapentin (Gpn) based analogue peptides. PMID- 29457826 TI - Prevalence of cardiometabolic risk factors among professional male long-distance bus drivers in Lagos, south-west Nigeria: a cross-sectional study. AB - BACKGROUND: Professional drivers are known to be at high risk of cardiovascular disease (CVD). This study was carried out to highlight these risk factors and their predictors among male long-distance professional bus drivers in Lagos, south-west Nigeria, with a view to improving health awareness in this group. METHOD: Socio-demographic data, anthropometric indices, blood pressure, fasting plasma blood glucose levels and lipid and physical activity profiles of 293 drivers were measured. RESULTS: Mean age of the study population was 48 +/- 9.7 years; 71.0 and 19.5% of the drivers used alcohol and were smokers, respectively; and 50.9% were physically inactive. The prevalence of overweight and obesity was 41.7 and 21.1%, respectively, while 39.7 and 13.9% were hypertensive and diabetic, respectively. Ninety (31.3%) subjects had impaired fasting glucose levels while 56.3% had dyslipidaemia. Predictors of hypertension were age and body mass index (BMI). BMI only was a predictor of abnormal glucose profile. CONCLUSION: Professional male long-distance bus drivers in this study showed a high prevalence of a cluster of risk factors for CVD. PMID- 29457827 TI - Percutaneous transmitral balloon commissurotomy using a single balloon with arteriovenous loop stabilisation: an alternative when there is no Inoue balloon. AB - BACKGROUND: The Inoue balloon technique is the standard technique for mitral valve balloon commissurotomy at this stage. However, the hardware for this technique is expensive and may not always be available in resource-limited settings. OBJECTIVE: This article reports our experience with percutaneous transmitral balloon commissurotomy using a single balloon (Nucleus) with arteriovenous loop stabilisation. METHOD: Eleven young patients, aged 12-26 years and weighing 23-48 kg, underwent transmitral balloon commissurotomy using the described technique at our centre from April to May 2014. RESULTS: Mean fluoroscopy time was 22.6 +/- 6.4 min (18.5- 30.0). Mean transmitral gradient decreased from 24.1 +/- 5.9 (16-35) to 6.6 +/- 3.8 (3-14) mmHg, as measured on transoesophageal echocardiography. Mean mitral valve area increased from 0.69 +/- 0.13 cm2 (range 0.5-0.9) before dilation to 1.44 +/- 0.25 cm2 (1.1-1.9) after dilation (p < 0.001). Mean estimated pulmonary artery systolic pressure decreased from 110.0 +/- 35 mmHg (75-170) before dilation to 28.0 +/- 14.4 mmHg (range 10 60) after dilation. CONCLUSION: Our modified Nucleus balloon technique for mitral valve dilation in young patients with mitral stenosis is effective and safe. The technique differs from other over-the-wire techniques in that it avoids placing stiff wire in the left ventricle. It also offers better balloon stability and control owing to the arteriovenous loop. This technique may be easier for use by paediatric interventionists who might not be familiar with the Inoue balloon technique. PMID- 29457829 TI - Species-specific susceptibility to cannabis-induced convulsions. AB - BACKGROUND AND PURPOSE: Numerous claims are made for cannabis' therapeutic utility upon human seizures, but concerns persist about risks. A potential confounder is the presence of both Delta9 -tetrahydrocannabinol (THC), variously reported to be pro- and anticonvulsant, and cannabidiol (CBD), widely confirmed as anticonvulsant. Therefore, we investigated effects of prolonged exposure to different THC/CBD cannabis extracts on seizure activity and associated measures of endocannabinoid (eCB) system signalling. EXPERIMENTAL APPROACH: Cannabis extract effects on in vivo neurological and behavioural responses, and on bioanalyte levels, were measured in rats and dogs. Extract effects on seizure activity were measured using electroencephalography telemetry in rats. eCB signalling was also investigated using radioligand binding in cannabis extract treated rats and treatment-naive rat, mouse, chicken, dog and human tissue. KEY RESULTS: Prolonged exposure to cannabis extracts caused spontaneous, generalized seizures, subserved by epileptiform discharges in rats, but not dogs, and produced higher THC, but lower 11-hydroxy-THC (11-OH-THC) and CBD, plasma concentrations in rats versus dogs. In the same rats, prolonged exposure to cannabis also impaired cannabinoid type 1 receptor (CB1 receptor)-mediated signalling. Profiling CB1 receptor expression, basal activity, extent of activation and sensitivity to THC suggested interspecies differences in eCB signalling, being more pronounced in a species that exhibited cannabis extract induced seizures (rat) than one that did not (dog). CONCLUSIONS AND IMPLICATIONS: Sustained cannabis extract treatment caused differential seizure, behavioural and bioanalyte levels between rats and dogs. Supporting radioligand binding data suggest species differences in eCB signalling. Interspecies variations may have important implications for predicting cannabis-induced convulsions from animal models. PMID- 29457828 TI - Dihydrodiosgenin protects against experimental acute pancreatitis and associated lung injury through mitochondrial protection and PI3Kgamma/Akt inhibition. AB - BACKGROUND AND PURPOSE: Acute pancreatitis (AP) is a painful and distressing disorder of the exocrine pancreas with no specific treatment. Diosgenyl saponins extracted from from Dioscorea zingiberensis C. H. Wright have been reported to protect against experimental models of AP. Diosgenin, or its derivatives are anti inflammatory in various conditions. However, the effects of diosgenin and its spiroacetal ring opened analogue, dihydrodiosgenin (Dydio), on AP have not been determined. EXPERIMENTAL APPROACH: Effects of diosgenin and Dydio on sodium taurocholate hydrate (Tauro)-induced necrosis were tested, using freshly isolated murine pancreatic acinar cells. Effects of Dydio on mitochondrial dysfunction in response to Tauro, cholecystokinin-8 and palmitoleic acid ethyl ester were also assessed. Dydio (5 or 10 mg.kg-1 ) was administered after the induction in vivo of Tauro-induced AP (Wistar rats), caerulein-induced AP and palmitoleic acid plus ethanol-induced AP (Balb/c mice). Pancreatitis was assessed biochemically and histologically. Activation of pancreatic PI3Kgamma/Akt was measured by immunoblotting. KEY RESULTS: Dydio inhibited Tauro-induced activation of the necrotic cell death pathway and prevented pancreatitis stimuli-induced mitochondrial dysfunction. Therapeutic administration of Dydio ameliorated biochemical and histopathological responses in all three models of AP through pancreatic mitochondrial protection and PI3Kgamma/Akt inactivation. Moreover, Dydio improved pancreatitis-associated acute lung injury through preventing excessive inflammatory responses. CONCLUSION AND IMPLICATIONS: These data provide in vitro and in vivo mechanistic evidence that the diosgenin analogue, Dydio could be potential treatment for AP. Further medicinal optimization of diosgenin and its analogue might be a useful strategy for identifying lead candidates for inflammatory diseases. PMID- 29457830 TI - miRNA-124-3p/neuropilin-1(NRP-1) axis plays an important role in mediating glioblastoma growth and angiogenesis. AB - Glioblastoma multiforme (GBM) is the most lethal brain malignancy which involves multi-gene abnormality. Unfortunately, effective therapy against GBM remains lacking. Previously, we found that NRP-1 and its downstream NRP-1/GIPC1 pathway played an important role in GBM. In our study, we further investigated the upstream signaling of NRP-1 to understand how it is regulated. First, we identified that hsa-miR-124-3p was miRNA differentially expressed in GBM and in normal brain tissues by high-throughput sequencing. Then, by dual luciferase reporter gene, we found miR-124-3p can specially bind to the 3'UTR region of the NRP-1 thus suppresses its expression. Moreover, miR-124-3p overexpression significantly inhibited GBM cell proliferation, migration and tumor angiogenesis which resulted in GBM apoptosis and cell cycle arrest, putatively via NRP-1 mediated PI3K/Akt/NFkappaB pathways activation in GBM cells. Meanwhile, miR-124 3p overexpression also suppressed tumor growth and reduced tumor angiogenesis when targeted by NRP-1 in a PDX model. Furthermore, NRP-1 mAb exerted synergistic inhibitory effects with miR-124-3p overexpression in GBM. Thus, we discovered that miR-124-3p acts as the upstream suppressor of NRP-1 which promotes GBM cell development and growth by PI3K/Akt/NFkappaB pathway. The miR-124-3p/NRP-1/GIPC1 pathway as a new pathway has a vital role in GBM, and it could be considered as the potential target for malignant gliomas in future. PMID- 29457831 TI - Low T3 syndrome as a predictor of poor prognosis in chronic lymphocytic leukemia. AB - Low triiodothyronine (T3) state is associated with poor prognosis in critical acute and prolonged illness. However, the information on thyroid dysfunction and cancer is limited. The aim of our study was to evaluate the prognostic value of low T3 syndrome in chronic lymphocytic leukemia (CLL). Two hundred and fifty eight patients with detailed thyroid hormone profile at CLL diagnosis were enrolled. Low T3 syndrome was defined by low free T3 (FT3) level accompanied by normal-to-low free tetraiodothyronine (FT4) and thyroid-stimulating hormone (TSH) levels. A propensity score-matched method was performed to balance the baseline characteristics. Multivariate Cox regression analyses screened the independent prognostic factors related to time-to-first-treatment (TTFT) and cancer-specific survival (CSS). Area under the curve (AUC) assessed the predictive accuracy of CLL-International Prognostic Index (IPI) together with low T3 syndrome. The results showed that 37 (14.34%) patients had low T3 syndrome, which was significantly associated with unfavorable TTFT and CSS in the propensity-matched cohort, and it was an independent prognostic indicator for both TTFT and CSS. Serum FT3 level was positively related to protein metabolism and anemia, and inversely related to inflammatory state. Patients with only low FT3 demonstrated better survival than those with synchronously low FT3 and FT4, while those with synchronously low FT3, FT4 and TSH had the worst clinical outcome. Low T3 syndrome together with CLL-IPI had larger AUCs compared with CLL-IPI alone in TTFT and CSS prediction. In conclusion, low T3 syndrome may be a good candidate for predicting prognosis in future clinical practice of CLL. PMID- 29457832 TI - Preferential conduction in arrhythmia ablation. PMID- 29457833 TI - A Green Method to Determine VUV (185 nm) Fluence Rate Based on Hydrogen Peroxide Production in Aqueous Solution. AB - A mini-fluidic vacuum ultraviolet/ultraviolet (VUV/UV) photoreaction system (MVPS) was developed in our previous study. Based on the MVPS, a green method to determine VUV fluence rate has been developed using the production rate of H2 O2 when water is exposed to 185 nm VUV. The H2 O2 production followed pseudo-zero order reaction kinetics well over the first 10 min of VUV/UV exposure. This new method was well calibrated with a standard cis-cyclooctene cis-trans photoisomerization actinometer as recommended by the International Union of Pure and Applied Chemistry. The apparent quantum yield for H2 O2 production by 185 nm VUV irradiation of water was determined to be 0.024 +/- 0.002. As the solution pH increased from 5.0 to 8.0, the H2 O2 production rate decreased from 0.83 to 0.40 MUm min-1 . Dissolved oxygen had a negligible influence on the H2 O2 production. This study proposes a novel VUV fluence rate determination method with advantages of nontoxicity, low detection limits, low costs and convenience, and it can be used as a good alternative to traditional actinometers.

PMID- 29457837 TI - Improved Wound Remodeling Correlates with Modulated TGF-beta Expression in Skin Diabetic Wounds Following Combined Red and Infrared Photobiomodulation Treatments. AB - Diabetic wounds are a major cause of morbidity among patients with poorly controlled blood glucose levels. Conventional empirical wound care strategies have shown limited efficacy, and there is an urgent need to develop novel therapeutic strategies. Photobiomodulation treatments have shown positive therapeutic effects in several cell culture and animal models. In this study, we examined wound healing in diabetic rats following treatments with two laser wavelengths, namely red (660 nm) and infrared (808 nm) individually and in combination as compared to routine wound dressings. Immunostaining for TGF-beta expression was performed at various times postwounding. We noted that the combination of red and infrared laser treatments correlated with decreased TGF beta1 levels at late stages in healing. There was no statistical significance with any treatments at an earlier time point. This study emphasizes the role of appropriate laser treatment protocols in modulating wound healing and remodeling responses. PMID- 29457836 TI - DEP domain-containing mTOR-interacting protein suppresses lipogenesis and ameliorates hepatic steatosis and acute-on-chronic liver injury in alcoholic liver disease. AB - : Alcoholic liver disease (ALD) is characterized by lipid accumulation and liver injury. However, how chronic alcohol consumption causes hepatic lipid accumulation remains elusive. The present study demonstrates that activation of the mechanistic target of rapamycin complex 1 (mTORC1) plays a causal role in alcoholic steatosis, inflammation, and liver injury. Chronic-plus-binge ethanol feeding led to hyperactivation of mTORC1, as evidenced by increased phosphorylation of mTOR and its downstream kinase S6 kinase 1 (S6K1) in hepatocytes. Aberrant activation of mTORC1 was likely attributed to the defects of the DEP domain-containing mTOR-interacting protein (DEPTOR) and the nicotinamide adenine dinucleotide-dependent deacetylase sirtuin 1 (SIRT1) in the liver of chronic-plus-binge ethanol-fed mice and in the liver of patients with ALD. Conversely, adenoviral overexpression of hepatic DEPTOR suppressed mTORC1 signaling and ameliorated alcoholic hepatosteatosis, inflammation, and acute-on chronic liver injury. Mechanistically, the lipid-lowering effect of hepatic DEPTOR was attributable to decreased proteolytic processing, nuclear translocation, and transcriptional activity of the lipogenic transcription factor sterol regulatory element-binding protein-1 (SREBP-1). DEPTOR-dependent inhibition of mTORC1 also attenuated alcohol-induced cytoplasmic accumulation of the lipogenic regulator lipin 1 and prevented alcohol-mediated inhibition of fatty acid oxidation. Pharmacological intervention with rapamycin alleviated the ability of alcohol to up-regulate lipogenesis, to down-regulate fatty acid oxidation, and to induce steatogenic phenotypes. Chronic-plus-binge ethanol feeding led to activation of SREBP-1 and lipin 1 through S6K1-dependent and independent mechanisms. Furthermore, hepatocyte-specific deletion of SIRT1 disrupted DEPTOR function, enhanced mTORC1 activity, and exacerbated alcoholic fatty liver, inflammation, and liver injury in mice. CONCLUSION: The dysregulation of SIRT1-DEPTOR-mTORC1 signaling is a critical determinant of ALD pathology; targeting SIRT1 and DEPTOR and selectively inhibiting mTORC1-S6K1 signaling may have therapeutic potential for treating ALD in humans.

AB - : Endoplasmic reticulum (ER) stress is activated in nonalcoholic fatty liver disease (NAFLD), raising the possibility that ER stress-dependent metabolic dysfunction, inflammation, and cell death underlie the transition from steatosis to steatohepatitis (nonalcoholic steatohepatitis; NASH). B-cell lymphoma 2 (BCL2) associated X protein (Bax) inhibitor-1 (BI-1), a negative regulator of the ER stress sensor, inositol-requiring enzyme 1 alpha (IRE1alpha), has yet to be explored in NAFLD as a hepatoprotective agent. We hypothesized that the genetic ablation of BI-1 would render the liver vulnerable to NASH because of unrestrained IRE1alpha signaling. ER stress was induced in wild-type and BI-1-/- mice acutely by tunicamycin (TM) injection (1 mg/kg) or chronically by high-fat diet (HFD) feeding to determine NAFLD phenotype. Livers of TM-treated BI-1-/- mice showed IRE1alpha-dependent NOD-like receptor family, pyrin domain containing 3 (NLRP3) inflammasome activation, hepatocyte death, fibrosis, and dysregulated lipid homeostasis that led to liver failure within a week. The analysis of human NAFLD liver biopsies revealed BI-1 down-regulation parallel to the up-regulation of IRE1alpha endoribonuclease (RNase) signaling. In HFD-fed BI-1-/- mice that presented NASH and type 2 diabetes, exaggerated hepatic IRE1alpha, X-box binding protein 1 (XBP1), and C/EBP homologous protein (CHOP) expression was linked to activated NLRP3 inflammasome and caspase-1/-11. Rises in interleukin (IL)-1beta, IL-6, monocyte chemoattractant protein 1 (MCP1), chemokine (C-X-C motif) ligand 1 (CXCL1), and alanine transaminase (ALT)/aspartate transaminase (AST) levels revealed significant inflammation and injury, respectively. Pharmacological inhibition of IRE1alpha RNase activity with the small molecules, STF-083010 or 4MU8c, was evaluated in HFD-induced NAFLD. In BI-1-/- mice, either treatment effectively counteracted IRE1alpha RNase activity, improving glucose tolerance and rescuing from NASH. The hepatocyte-specific role of IRE1alpha RNase activity in mediating NLRP3 inflammasome activation and cell death was confirmed in primary mouse hepatocytes by IRE1alpha axis knockdown or its inhibition with STF 083010 or 4MU8c. CONCLUSION: Targeting IRE1alpha-dependent NLRP3 inflammasome signaling with pharmacological agents or by BI-1 may represent a tangible therapeutic strategy for NASH. (Hepatology 2018).

AB - BACKGROUND: Adenoviruses are double-stranded DNA viruses that typically cause mild self-limiting respiratory, ocular, and gastrointestinal infections. In immunocompromised patients, especially transplant recipients, the infection can be severe, with dissemination and multiorgan failure. In intestinal transplant recipients, the incidence is as high as 57%. To our knowledge, no standardized guidelines or U.S. Food and Drug Administration-approved medications exist for the treatment of adenovirus disease. AIMS: We describe two isolated intestinal transplant recipients who developed adenovirus disease (viremia with viral enteritis) that was managed with a new experimental drug, brincidofovir (an oral lipid conjugate prodrug of cidofovir), as salvage therapy. RESULTS: The first patient was a 44-year-old woman who developed adenoviral enteritis 1 month after transplantation, which resolved with ribavirin therapy. Two weeks later, the infection recurred, and brincidofovir was initiated. While receiving this therapy for 3 months, she developed severe acute rejection, which was managed with rabbit antithymocyte globulin followed by infliximab. Eventually, complete resolution of the rejection and adenoviral enteritis was achieved. At 12 months posttransplantation, the patient was healthy and tolerating enteral feeding. The second patient was a 28-year-old man who had undergone isolated intestinal transplantation 6 years before he presented with generalized weakness and an increased ostomy output; he was diagnosed with adenoviral enteritis. Maintenance immunosuppression was reduced, and brincidofovir was started. The infection resolved with a month of therapy. Six months after the infection, he was healthy and tolerating enteral feeding. CONCLUSION: This is the first publication, to our knowledge, to describe two cases in which brincidofovir was used to successfully treat adenovirus infection in intestinal transplant recipients. Thus, these cases demonstrate that brincidofovir appears to be a safe and effective option in the management of adenoviral enteritis in these patients.

PMID- 29457840 TI - Population pharmacokinetics and pharmacogenomics of apixaban in Japanese adult patients with atrial fibrillation. AB - AIMS: This study aimed to analyse the effects of genetic polymorphisms in drug transporters and metabolizing enzymes, and clinical laboratory data on the pharmacokinetic parameters of apixaban. METHODS: Data were collected from 81 Japanese patients with atrial fibrillation. Pharmacogenomic data were stratified by ABCB1, ABCG2 and CYP3A5 polymorphisms. The pharmacokinetic profile of apixaban was described by a one-compartment model with first-order absorption. Population pharmacokinetic analysis was conducted using a nonlinear mixed effect modelling (NONMEMTM) program. RESULTS: The nonlinear relationship between oral clearance (CL/F) of apixaban and creatinine clearance (Ccr) was observed. The population mean of CL/F for a typical patient (Ccr value of 70 ml min-1 ) with the CYP3A5*1/*1 and ABCG2 421C/C or C/A genotypes was estimated to be 3.06 l h-1 . When Ccr values were set to the typical value, the population mean of CL/F was 1.52 times higher in patients with the CYP3A5*1/*1 genotype compared with patients with the CYP3A5*1/*3 or *3/*3 genotype, while the population mean of CL/F was 1.49 times higher in patients with the ABCG2 421C/C or C/A genotype compared with patients with the ABCG2 421A/A genotype. However, no covariates affected the population mean of the apparent volume of distribution (Vd/F) of apixaban. The population mean of Vd/F was estimated to be 24.7 l. CONCLUSION: The present study suggests that the ABCG2 421A/A and CYP3A5*3 genotypes and renal function are intrinsic factors affecting apixaban pharmacokinetics. These findings may provide useful information for precision medicine using apixaban, to avoid the risk of adverse reactions. PMID- 29457842 TI - Long-term outcomes of patients undergoing simultaneous liver transplantation and sleeve gastrectomy. AB - : Obesity is increasingly common before and after liver transplantation (LT), yet optimal management remains unclear. The aim of this study was to analyze the long term outcomes for obese patients undergoing LT, including a noninvasive weight loss program and combined LT and sleeve gastrectomy (SG). Since 2006, all patients referred for LT with a body mass index (BMI) >=35 kg/m2 were enrolled. Patients who achieved weight loss (BMI <35) underwent LT alone, and those who did not underwent simultaneous LT + SG. Analysis of long-term outcomes for patients >=3 years posttransplant was performed. Since 2006, there were 36 in the weight loss intervention (LT cohort) and 13 in the LT + SG cohort with >3 years of follow-up, whereas overall, a total of 29 patients underwent LT + SG. Patients in the LT cohort had less severe obesity at enrollment (40.0 +/- 2.7 vs. LT + SG cohort 46.0 +/- 4.5; P < 0.001). In the LT cohort, 83.3% (30 of 36) achieved >10% loss in total body weight (TBW) pre-LT. Three years posttransplant, 29.4% of patients in the LT cohort maintained >10% loss in TBW, whereas 100% of the LT + SG patients did (P < 0.001). Patients who underwent LT + SG maintained a significantly higher percentage of total body weight loss after 3 years of follow up (LT cohort 3.9 +/- 13.3% vs. LT + S G cohort 34.8 +/- 17.3%; P < 0.001). Patients in the LT + SG also had a lower prevalence of hypertension, insulin resistance, and hepatic steatosis and required fewer antihypertensive medications and lipid agents at last follow-up. CONCLUSION: Whereas weight loss before transplantation was achieved by obese patients, weight regain was common in the LT cohort. Combined LT + SG resulted in more effective and more durable weight loss, as well as fewer metabolic complications at last follow-up. (Hepatology 2018). PMID- 29457843 TI - The tumour-stroma ratio in colon cancer: the biological role and its prognostic impact. AB - The tumour microenvironment consists of a complex mixture of non-neoplastic cells, including fibroblasts, immune cells and endothelial cells embedded in the proteins of the extracellular matrix. The tumour microenvironment plays an active role in tumour behaviour. By interacting with cancer cells, it influences disease progression and the metastatic capacity of the tumour. Tumours with a high amount of stroma correspond to poor patient prognosis. The tumour-stroma ratio (TSR) is a strong independent prognostic tool in colon cancer and provides additional value to the current clinically used tumour-node-metastasis classification. The TSR is assessed on conventional haematoxylin and eosin-stained paraffin sections at the invasive front of the tumour. Here we review studies demonstrating the prognostic significance of the TSR in solid epithelial tumours with a focus on colon cancer. Moreover, the biological role of the tumour microenvironment during tumour progression and invasion will be discussed, as well as the attempts to target the tumour stroma for therapeutic purposes. We suggest that the TSR can be implemented with little effort and without additional costs in current routine pathology diagnostics owing to its simplicity and reliability. PMID- 29457844 TI - Effect of type D personality on smoking status and their combined impact on outcome after acute myocardial infarction. AB - BACKGROUND: Smoking cessation is correlated with several psychological, social, biological, and pharmacological aspects. The combined tendency to experience negative emotions and to inhibit the expression of these emotions is indicated as "type D personality," an independent risk marker for clinical outcome in cardiac disease. Despite this effect of type D personality on cardiovascular disease, it is still unclear whether this personality trait may influence smoking cessation after a myocardial infarction. HYPOTHESIS: we hypothesized that there is a relationship between type D personality and smoking persistence in acute coronary syndrome patients, and this association may predict a worse long-term prognosis. METHODS: The study enrolled 231 patients with ST-segment elevation myocardial infarction, treated with primary percutaneous coronary intervention. Type D scale 14 (ds 14) was administered upon admission to the hospital. RESULTS: After controlling for demographic and clinical confounders, non-type D patients reported statistically significant higher frequencies of smoking cessation when compared with the type D group. In addition, the presence of this psychological factor anticipates significantly the onset of smoking during adolescence. Furthermore, current type D smokers had a higher incidence of cardiovascular events during long-term follow-up. CONCLUSIONS: Type D personality and smoking status increase the risk of cardiac events. An emotionally stressed personality and persistence of smoking after the first cardiac event, and mostly their mutual influence, indicate a population at high cardiovascular risk.

AB - OBJECTIVE: The Dark Tetrad traits (subclinical psychopathy, narcissism, Machiavellianism, and everyday sadism) have interpersonal consequences. At present, however, how these traits are associated with the accuracy and positivity of first impressions is not well understood. The present article addresses three primary questions. First, to what extent are perceiver levels of Dark Tetrad traits associated with differing levels of perceptive accuracy? Second, to what extent are target levels of Dark Tetrad traits associated with differing levels of expressive accuracy? Finally, to what extent can Dark Tetrad traits be differentiated when examining perceptions of and by others? METHOD: In a round-robin design, undergraduate participants (N = 412) in small groups engaged in brief, naturalistic, unstructured dyadic interactions before providing impressions of their partner. RESULTS: Dark Tetrad traits were associated with being viewed and viewing others less distinctively accurately and more negatively. CONCLUSIONS: Interpersonal perceptions that included an individual scoring highly on one of the Dark Tetrad traits differed in important ways from interactions among individuals with more benevolent personalities. Notably, despite the similarities between the Dark Tetrad, traits had unique associations with interpersonal perceptions. PMID- 29457847 TI - Preconditioning With Low-Level Laser Irradiation Enhances the Therapeutic Potential of Human Adipose-derived Stem Cells in a Mouse Model of Photoaged Skin. AB - This study was conducted to explore the therapeutic potential of human adipose derived stem cells (ADSCs) irradiated with a low-level laser (LLL). Cultured ADSCs were treated with 650-nm GaAlAs laser irradiation at 2, 4 and 8 J cm-2 . Cell proliferation was quantified by MTT assays, cytokine secretion was determined by enzyme-linked immunosorbent assays, and adipogenic differentiation was examined by oil red O staining. Additionally, the expression profiles of putative ADSC surface markers were analyzed by quantitative real-time PCR. In addition, a mouse photoaged skin model was established by UVB irradiation. Effects of GaAlAs laser-treated ADSCs on the thicknesses of the epidermis and dermis were analyzed by hematoxylin and eosin staining. The results showed that GaAlAs laser treatment of cells at a radiant exposure of 4 J cm-2 enhanced ADSC proliferation and adipogenic differentiation and increased secretion of growth factors. Furthermore, GaAlAs laser irradiation upregulated the expression of putative ADSC surface markers. In the mouse model of photoaged skin, ADSCs treated with GaAlAs laser irradiation had markedly decreased the epidermal thickness and increased the dermal thickness of photoaged mouse skin. Our data indicate that LLL irradiation is an effective biostimulator of ADSCs and might enhance the therapeutic potential of ADSCs for clinical use. PMID- 29457848 TI - Effects of chronic heat exposure on growth performance, intestinal epithelial histology, appetite-related hormones and genes expression in broilers. AB - BACKGROUND: Heat stress often occurs in the modern poultry industry, which impairs growth performance, particularly via reducing appetite. This study was aimed to investigate the mechanism of attenuating appetite by chronic heat exposure in broilers. A total of 144 broilers (28 days old) were allocated to normal control (NC, 22 degrees C), heat stress (32 degrees C), and pair-fed (22 degrees C) groups. RESULTS: Chronic heat exposure significantly increased cloacal temperatures and respiration rates, decreased the average daily feed intake and average daily gain, increased feed-to-gain ratio compared with the NC group, and elevated the concentrations of ghrelin and cholecystokinin (CCK) both in serum and intestine, as well as peptide YY and somatostatin in intestine on 35 or 42-day-old broilers. Moreover, heat exposure decreased villi height (VH) and the ratio of VH to crypt depth (CD), while it increased CD in the jejunum on 35- and 42 day-olds, increased (P < 0.05) the concentrations of valine and isoleucine in plasma on 42 days, and upregulated (P < 0.05) the expression of taste receptor type 1 members 1 and 3 (T1R1 and T1R3), CCK, and ghrelin in the intestine on 35- or 42-day-old broilers. CONCLUSION: Chronic heat exposure impairs the performance, intestinal morphology and appetite, which may be correlated with the increased secretion or gene expression of appetite-related hormones and genes, and the higher expression of nutrient-sensing receptors (T1R1 and T1R3) in broilers.

AB - Smoking is a major preventable cause of cancers and is increasingly concentrated among the most deprived individuals leading to increasing socioeconomic inequalities in the incidence of cancers linked to smoking. We aimed to estimate the tobacco-attributable cancer burden according to socioeconomic position in France. The analysis was restricted to cancer sites for which tobacco smoking was recognized as a risk factor. Cancer cases by sex, age group and European Deprivation Index (EDI) among people aged 30-74 between 2006 and 2009 were obtained from cancer registries covering ~20% of the French population. The tobacco-attributable burden of cancer according to EDI was estimated applying the population attributable fraction (PAF) computed with the Peto-Lopez method. The PAF increased from 56% in the least deprived EDI quintile to 70% in the most deprived EDI quintile among men and from 26% to 38% among women. In total, 28% of the excess cancer cases in the four most deprived EDI quintiles in men and 43% in women could be prevented if smoking in these 4 EDI quintiles was similar to that of the least deprived EDI quintile. A substantial smoking-attributable burden of cancer by socioeconomic position was observed in France. The results highlight the need for policies reducing tobacco consumption. More comprehensive interventions integrating the various dimensions of health determinants and proportionate according to socioeconomic position may essentially contribute to the reduction of socioeconomic inequalities in cancer. PMID- 29457850 TI - Preparation, aroma characteristics and volatile compounds of flavorings from enzymatic hydrolyzed rice bran protein concentrate. AB - BACKGROUND: Rice bran is a by-product obtained from the rice milling industry. The aims of this research were to add value to rice bran by preparation of enzymatic hydrolyzed rice bran protein concentrate (HRPC) as a flavoring agent and the flavoring which was produced by HRPC has not been investigated. Different drying methods (freeze-drying and spray-drying) and fructose additions were studied for improvement of rice bran protein sensorial aroma characteristics. RESULTS: The most abundant amino acids in liquid HRPC (LH) were glutamic acid, arginine, aspartic acid and leucine. The intensity of desirable aromas, such as cereal-like, nut-like, milk-powder-like, sweet, and cocoa-like aroma, were higher in spray-dried HRPC powder (SHP) than in LH and freeze-dried HRPC. Volatile compounds, such as aldehydes, pyrazines and ketones, were significantly increased in HRPC powders in which fructose was added before spray-drying (SHP-F). Higher amounts of 2-methylbutanal, 3-methylbutanal, phenylacetaldehyde, 2,5 dimethylpyrazine, vanillin, 2-acetylpyrrole and maltol were detected in SHP-F. Moreover, these compounds had high odor active values, which accounted for the cocoa-like, sweet, nut-like, and milk-powder-like characteristics of SHP-F. CONCLUSIONS: These findings could lead to the creation of desirable aroma characteristics of rice bran protein concentrate by different preparation methods. (c) 2018 Society of Chemical Industry. PMID- 29457851 TI - Suppression of microRNA-144-3p attenuates oxygen-glucose deprivation/reoxygenation-induced neuronal injury by promoting Brg1/Nrf2/ARE signaling. AB - Accumulating evidence has reported that microRNA-144-3p (miR-144-3p) is highly related to oxidative stress and apoptosis. However, little is known regarding its role in cerebral ischemia/reperfusion-induced neuronal injury. Herein, our results showed that miR-144-3p expression was significantly downregulated in neurons following oxygen-glucose deprivation and reoxygenation (OGD/R) treatment. Overexpression of miR-144-3p markedly reduced cell viability, promoted cell apoptosis, and increased oxidative stress in neurons with OGD/R treatment, whereas downregulation of miR-144-3p protected neurons against OGD/R-induced injury. Brahma-related gene 1 (Brg1) was identified as a potential target gene of miR-144-3p. Moreover, downregulation of miR-144-3p promoted the nuclear translocation of nuclear factor erythroid 2-related factor 2 (Nrf2) and increased antioxidant response element (ARE) activity. However, knockdown of Brg1 significantly abrogated the neuroprotective effects of miR-144-3p downregulation. Overall, our results suggest that miR-144-3p contributes to OGD/R-induced neuronal injury in vitro through negatively regulating Brg1/Nrf2/ARE signaling. PMID- 29457852 TI - Successful management of living donor liver transplantation for biliary atresia with single ventricle physiology-from peri-transplant through total cavopulmonary connection: A case report. AB - Children with single ventricle physiology have complete mixing of the pulmonary and systemic circulations, requiring staged procedures to achieve a separation of these circulations, or Fontan circulation. The single ventricle physiology significantly increases the risk of mortality in children undergoing non-cardiac surgery. As liver transplantation for patients with single ventricle physiology is particularly challenging, only a few reports have been published. We herein report a case of successful LDLTx for an 8-month-old pediatric patient with biliary atresia, heterotaxy, and complex heart disease of single ventricle physiology. The cardiac anomalies included total anomalous pulmonary venous return type IIb, intermediate atrioventricular septal defect, tricuspid regurgitation grade III, coarctation of aorta, interrupted inferior vena cava, bilateral superior vena cava, and polysplenia syndrome. Following LDLTx, the patient sequentially underwent total cavopulmonary shunt + Damus-Kaye-Stansel at 3 years of age and extracardiac total cavopulmonary connection (EC-TCPC) completion at 5 years of age; 7 years have now passed since LDLTx (2 years post EC-TCPC). We describe the details of the management of LTx in the presence of cardiac anomalies and report the long-term cardiac and liver function, from peri LDLTx through EC-TCPC completion. PMID- 29457853 TI - Mesenchymal-epithelial transition of pancreatic cancer cells at perineural invasion sites is induced by Schwann cells. AB - Epithelial-mesenchymal transition (EMT) promotes invasion and metastasis of pancreatic ductal adenocarcinoma (PDAC). However, the importance of its reverse process, mesenchymal-epithelial transition (MET), for PDAC remains unclear. We aimed to characterize the histological finding "focal differentiation" in PDAC at perineural invasion sites in the context of MET and to investigate the role of Schwann cells in inducing tumor MET. Tumor differentiation and immunohistochemical expressions of E-cadherin, SMAD3, and vimentin at perineural invasion sites were examined in 168 PDAC tissues. Four PDAC cell lines were co cultured with Schwann cells to investigate cell morphology, motility, or EMT related markers using immunocytochemistry and quantitative PCR. Of 168 tumors, 124 (74%) showed focal differentiation with enhanced E-cadherin membrane expression (P < 0.001) and decreased nuclear accumulation of SMAD3 (P < 0.001). Among 115 PDACs harboring grade 1/2 tumor, tumors with focal differentiation showed worse survival compared to those without focal differentiation (P = 0.019). PDAC cells co-cultured with Schwann cells demonstrated a sheet-like appearance, increased E-cadherin expression, decreased expressions of SMAD3 and vimentin, and reduced cell motility. In conclusion, MET-like change is induced by Schwann cells, suggesting that Schwann cells contribute to PDAC colonization in pancreatic nerves through activating the MET machinery inside tumor cells in the pancreatic tumor microenvironment. PMID- 29457854 TI - Metal Cluster Models for Heterogeneous Catalysis: A Matrix-Isolation Perspective. AB - Metal cluster models are of high relevance for establishing new mechanistic concepts for heterogeneous catalysis. The high reactivity and particular selectivity of metal clusters is caused by the wealth of low-lying electronically excited states that are often thermally populated. Thereby the metal clusters are flexible with regard to their electronic structure and can adjust their states to be appropriate for the reaction with a particular substrate. The matrix isolation technique is ideally suited for studying excited state reactivity. The low matrix temperatures (generally 4-40 K) of the noble gas matrix host guarantee that all clusters are in their electronic ground-state (with only a very few exceptions). Electronically excited states can then be selectively populated and their reactivity probed. Unfortunately, a systematic research in this direction has not been made up to date. The purpose of this review is to provide the grounds for a directed approach to understand cluster reactivity through matrix-isolation studies combined with quantum chemical calculations. PMID- 29457855 TI - Experimental study on TGF-beta1-mediated CD147 expression in oral submucous fibrosis. AB - OBJECTIVE: Although previous evidence indicates that CD147 is closely involved in the progression of organ fibrosis and various signaling pathways have been proven to regulate its expression, the role of CD147 in oral submucous fibrosis (OSF) remains largely unknown. METHODS: In this study, we investigated the expression of CD147 and transforming growth factor beta1 (TGF-beta1) in human samples of an OSF tissue array by immunohistopathology. Pearson's correlation analysis was conducted to explore the correlation between CD147 and TGF-beta1. Immunofluorescence and Western blotting were used to investigate to levels of CD147 in Human Oral Keratinocytes (HOKs) followed by TGF-beta1 or LY2157299, an inhibitor of TGF-beta1 receptor and arecoline stimulation. RESULTS: We found that CD147 was highly expressed in both HOKs and the fibrotic oral mucosa and that this expression was correlated with TGF-beta1 expression. Additionally, CD147 levels were significantly associated with the fibrosis stage. The TGF-beta1 signaling pathway was found to be mainly responsible for CD147 up-regulation after arecoline treatment whereas inhibition of TGF-beta1 down-regulated CD147 expression. CONCLUSION: Our findings suggest arecoline promotes CD147 expression via the TGF-beta1 signaling pathway in HOKs, whereas overexpression of CD147 may promote OSF progression. PMID- 29457856 TI - Dual-Input Regulation and Positional Control in Hybrid Oligonucleotide/Discotic Supramolecular Wires. AB - The combination of oligonucleotides and synthetic supramolecular systems allows for novel and long-needed modes of regulation of the self-assembly of both molecular elements. Discotic molecules were conjugated with short oligonucleotides and their assembly into responsive supramolecular wires studied. The self-assembly of the discotic molecules provides additional stability for DNA duplex formation owing to a cooperative effect. The appended oligonucleotides allow for positional control of the discotic elements within the supramolecular wire. The programmed assembly of these hybrid architectures can be modulated through the DNA, for example, by changing the number of base pairs or salt concentration, and through the discotic platform by the addition of discotic elements without oligonucleotide handles. These hybrid supramolecular-DNA structures allow for advanced levels of control over 1D dynamic platforms with responsive regulatory elements at the interface with biological systems. PMID- 29457857 TI - Structural Studies of Self-Assembled Subviral Particles: Combining Cell-Free Expression with 110 kHz MAS NMR Spectroscopy. AB - Viral membrane proteins are prime targets in combatting infection. Still, the determination of their structure remains a challenge, both with respect to sample preparation and the need for structural methods allowing for analysis in a native like lipid environment. Cell-free protein synthesis and solid-state NMR spectroscopy are promising approaches in this context, the former with respect to its great potential in the native expression of complex proteins, and the latter for the analysis of membrane proteins in lipids. Herein, we show that milligram amounts of the small envelope protein of the duck hepatitis B virus (DHBV) can be produced by cell-free expression, and that the protein self-assembles into subviral particles. Proton-detected 2D NMR spectra recorded at a magic-angle spinning frequency of 110 kHz on <500 MUg protein show a number of isolated peaks with line widths comparable to those of model membrane proteins, paving the way for structural studies of this protein that is homologous to a potential drug target in HBV infection.

AB - Chemical functionalization of covalent organic frameworks (COFs) is critical for tuning their properties and broadening their potential applications. However, the introduction of functional groups, especially to three-dimensional (3D) COFs, still remains largely unexplored. Reported here is a general strategy for generating a 3D carboxy-functionalized COF through postsynthetic modification of a hydroxy-functionalized COF, and for the first time exploration of the 3D carboxy-functionalized COF in the selective extraction of lanthanide ions. The obtained COF shows high crystallinity, good chemical stability, and large specific surface area. Furthermore, the carboxy-functionalized COF displays high metal loading capacities together with excellent adsorption selectivity for Nd3+ over Sr2+ and Fe3+ as confirmed by the Langmuir adsorption isotherms and ideal adsorbed solution theory (IAST) calculations. This study not only provides a strategy for versatile functionalization of 3D COFs, but also opens a way to their use in environmentally related applications. PMID- 29457859 TI - Post-infectious acute glomerulonephritis with podocytopathy induced by parvovirus B19 infection. AB - Human parvovirus B19 infection causes a variety of glomerular diseases such as post-infectious acute glomerulonephritis and collapsing glomerulopathy. Although each of these appears independently, it has not been fully determined why parvovirus B19 provokes such a variety of different glomerular phenotypes. Here, we report a 68-year-old Japanese man who showed endocapillary proliferative glomerulonephritis admixed with podocytopathy in association with parvovirus B19 infection. The patient showed acute onset of heavy proteinuria, microscopic hematuria and kidney dysfunction with arthralgia and oliguria after close contact with a person suffering from erythema infectiosum. In the kidney biopsy specimen, glomeruli revealed diffuse and global endocapillary infiltration of inflammatory cells, with some also showing tuft collapse with aberrant vacuolation, swelling, and hyperplasia of glomerular epithelial cells. Immunofluorescence revealed dense granular C3 deposition that resembled the "starry sky pattern". Intravenous glucocorticoid pulse therapy followed by oral prednisolone and cyclosporine combination therapy resulted in considerable amelioration of the kidney dysfunction and urinary abnormalities. The present case reveals that parvovirus B19 infection can induce different glomerular phenotypes even in the same kidney structure. This finding may provide hints useful for the further elucidation of the pathogenesis of parvovirus B19-induced glomerular lesions. PMID- 29457860 TI - Controlling the Outgrowth and Functions of Neural Stem Cells: The Effect of Surface Topography. AB - Neural stem cells (NSCs) are self-renewing cells that generate the major cell types of the central nervous system, namely neurons, astrocytes and oligodendrocytes, during embryonic development and in the adult brain. NSCs reside in a complex niche where they are exposed to a plethora of signals, including both soluble and physical signals such as compressive and shear stresses, but also discontinuities and differences in morphology of the extracellular environment, termed as topographical features. Different approaches that incorporate artificial micro- and nano-scale surface topographical features have been developed aiming to recapitulate the in vivo NSC niche discontinuities and features, particularly for in vitro studies. The present review article aims at reviewing the existing body of literature on the use of artificial micro- and nano-topographical features to control NSCs orientation and differentiation into neuronal and/or neuroglial lineage. The different approaches on the study of the underlying mechanism of the topography-guided NSC responses are additionally revised and discussed. PMID- 29457861 TI - Promoted Fixation of Molecular Nitrogen with Surface Oxygen Vacancies on Plasmon Enhanced TiO2 Photoelectrodes. AB - A hundred years on, the energy-intensive Haber-Bosch process continues to turn the N2 in air into fertilizer, nourishing billions of people while causing pollution and greenhouse gas emissions. The urgency of mitigating climate change motivates society to progress toward a more sustainable method for fixing N2 that is based on clean energy. Surface oxygen vacancies (surface Ovac ) hold great potential for N2 adsorption and activation, but introducing Ovac on the very surface without affecting bulk properties remains a great challenge. Fine tuning of the surface Ovac by atomic layer deposition is described, forming a thin amorphous TiO2 layer on plasmon-enhanced rutile TiO2 /Au nanorods. Surface Ovac in the outer amorphous TiO2 thin layer promote the adsorption and activation of N2 , which facilitates N2 reduction to ammonia by excited electrons from ultraviolet-light-driven TiO2 and visible-light-driven Au surface plasmons. The findings offer a new approach to N2 photofixation under ambient conditions (that is, room temperature and atmospheric pressure). PMID- 29457862 TI - Peter J. Dunn Award: B. H. Lipshutz and S.

PMID- 29457863 TI - The B-type natriuretic peptide is a useful biomarker for the estimation of volume overload in children with hypertension in children on peritoneal dialysis. AB - AIM: To evaluate the usefulness of serum B-type natriuretic peptide (BNP) as a biomarker of fluid retention in hypertensive children on peritoneal dialysis (PD). METHODS: We included hypertensive children on PD. We reviewed the changes (?) of body weight (BWt), blood pressure (BP) and serum BNP at initial and follow up periods. We presented data as mean+/-standard deviation (median, minimum - maximum). Wilcoxon signed-rank test was used to evaluate the changes in BWt, BP, and BNP. We applied linear regression analysis for the correlation between the changes of BNP and BP. RESULTS: We evaluated 56 hypertensive events in 30 patients. Initial findings were BWt 30.5+/-22.4 (26.5, 3.0 - 93.5) kg, systolic BP (SBP) 153.3+/-21.5 (150, 110 - 241) mmHg, diastolic BP (DBP) 100.1+/-22.3, (99.5, 49 - 181) mmHg, BNP 3579.3+/-6328.9 (1198.5, 305 - 22028) pg/mL. Follow-up results were BWt 29.1+/-21.3 (25.0, 3.12 - 86) kg, SBP 116.4+/-17.8 (117.5, 82 - 150) mmHg, DBP 73.3+/-14.2 (75.0, 42.0 - 101.0) mmHg, BNP 63.5+/-49.2 (60.5, 2 - 261) pg/mL. ?SBP (-23.1+/-13.8, -22.8, -46.9 - 22.5%, P<0.001), ?DBP (-24.1+/ 19.2, -24.7, -55.6 - 23.2%, P<0.001) and ?BNP (-93.5+/-8.1, -96.7, -99.9 - 61.0%, P<0.001) dropped significantly after reduction of ?BWt (-4.8+/-4.7, -4.8, 18.7 - 5.6%, P<0.001). The ?BNP were significantly correlated with ?SBP (adjusted R square = 0.221, P<0.001) and ?DBP ( adjusted R square = 0.203, P < 0.001). CONCLUSIONS: We should measure BNP in hypertensive patients on PD to evaluate the volume status. PMID- 29457864 TI - Promotion of a Reaction by Cooling: Stereoselective 1,2-cis-alpha Thioglycoconjugation by Thiol-Ene Coupling at -80 degrees C. AB - The photoinitiated thiol-ene coupling reactions of 2-substituted glycals were studied as a generally applicable strategy for stereoselective 1,2-cis-alpha thioconjugation. Although all glycals reacted with full alpha-selectivity, the efficacy of the reactions varied in a broad range depending on their configuration and glycals bearing axial acetoxy substituents reacted with very low efficacy at room temperature. The study revealed that the reaction progress could be promoted by cooling and inhibited by heating. At -80 degrees C, the equilibrium of the rapidly reversible addition of the thiyl radical to alkenes is shifted almost completely toward products, leading to efficient addition reactions. By exploiting this unique temperature effect a series of alpha-thio-l fucosides, -d-galactosides, and d-GlcNAc derivatives were prepared with high efficacy and complete stereoselectivity. PMID- 29457866 TI - Epigenetic effects of metformin: From molecular mechanisms to clinical implications. AB - There is a growing body of evidence that links epigenetic modifications to type 2 diabetes. Researchers have more recently investigated effects of commonly used medications, including those prescribed for diabetes, on epigenetic processes. This work reviews the influence of the widely used antidiabetic drug metformin on epigenomics, microRNA levels and subsequent gene expression, and potential clinical implications. Metformin may influence the activity of numerous epigenetic modifying enzymes, mostly by modulating the activation of AMP activated protein kinase (AMPK). Activated AMPK can phosphorylate numerous substrates, including epigenetic enzymes such as histone acetyltransferases (HATs), class II histone deacetylases (HDACs) and DNA methyltransferases (DNMTs), usually resulting in their inhibition; however, HAT1 activity may be increased. Metformin has also been reported to decrease expression of multiple histone methyltransferases, to increase the activity of the class III HDAC SIRT1 and to decrease the influence of DNMT inhibitors. There is evidence that these alterations influence the epigenome and gene expression, and may contribute to the antidiabetic properties of metformin and, potentially, may protect against cancer, cardiovascular disease, cognitive decline and aging. The expression levels of numerous microRNAs are also reportedly influenced by metformin treatment and may confer antidiabetic and anticancer activities. However, as the reported effects of metformin on epigenetic enzymes act to both increase and decrease histone acetylation, histone and DNA methylation, and gene expression, a significant degree of uncertainty exists concerning the overall effect of metformin on the epigenome, on gene expression, and on the subsequent effect on the health of metformin users. PMID- 29457865 TI - Nucleophilic Substitution in Solution: Activation Strain Analysis of Weak and Strong Solvent Effects. AB - We have quantum chemically studied the effect of various polar and apolar solvents on the shape of the potential energy surface (PES) of a diverse collection of archetypal nucleophilic substitution reactions at carbon, silicon, phosphorus, and arsenic by using density functional theory at the OLYP/TZ2P level. In the gas phase, all our model SN 2 reactions have single-well PESs, except for the nucleophilic substitution reaction at carbon (SN 2@C), which has a double-well energy profile. The presence of the solvent can have a significant effect on the shape of the PES and, thus, on the nature of the SN 2 process. Solvation energies, charges on the nucleophile or leaving group, and structural features are compared for the various SN 2 reactions in a spectrum of solvents. We demonstrate how solvation can change the shape of the PES, depending not only on the polarity of the solvent, but also on how the charge is distributed over the interacting molecular moieties during different stages of the reaction. In the case of a nucleophilic substitution at three-coordinate phosphorus, the reaction can be made to proceed through a single-well [no transition state (TS)], bimodal barrier (two TSs), and then through a unimodal transition state (one TS) simply by increasing the polarity of the solvent.

AB - The brominated and mixed bromo-chloro-haloacetates, such as dibromoacetate (DBA), bromochloroacetate (BCA), and bromodichloroacetate (BDCA), are by-products of water chlorination and are found at lower levels than the fully chlorinated acetates in the drinking water. The toxicities of the compounds were assessed in J774A.1 cells and were found to induce concentration-dependent increases in cell death and superoxide anion and protein carbonyl compounds production. Compared to the previously tested concentrations of dichoroacetate (DCA) and trichloroacetate (TCA) in the same cell line, the tested haloacetates induced similar effects on cellular viability and superoxide anion production but at DBA and BCA concentrations that were approximately 40-160 times lower than those of DCA and TCA, and at BDCA concentrations that were 4-16 times lower than those of DCA and TCA. Also, production of super oxide anion, protein carbonyl compounds, and induction of phagocytic activation are suggested to play a role in their toxicity.

AB - INTRODUCTION: Female sex workers (FSWs) are at high-risk for HIV acquisition in South Africa, where the advent of new HIV prevention and treatment interventions represent the potential to significantly impact the epidemic. This paper focuses on aspects of PrEP acceptability as a new intervention within the context of a larger service delivery programme including the simultaneous rollout of early ART. This paper explores PrEP acceptability among the FGD participants as future potential users. METHODS: FGDs were conducted in two clinic-based sites in Johannesburg and Pretoria. They aimed to explore community-level, multi dimensional acceptability of PrEP within the context of imminent implementation alongside early ART in the TAPS Demonstration Project. Sex worker peer educators recruited participants from varying sex work locales. Facilitation was in English with adaptation by facilitators into local languages as needed. Transcripts were translated and transcribed into English. Thematic analysis was used to analyse the data. RESULTS: Four FGDs were conducted in each site for a total of eight FDGs and 69 participants. Demographics were largely similar across the sites. Overall, there was strong acceptability of PrEP among participants and positive anticipation for the imminent delivery of PrEP in the local sex worker clinics. Themes arising from the discussions exploring aspects of PrEP acceptability included: awareness and understanding of PrEP; PrEP motivations including choice, control, and vulnerability, managing PrEP risks and worries; and, de-stigmatizing and empowering PrEP delivery. Participant discussions and recommendations highlighted the importance of developing clear education and messaging to accurately convey the concept of PrEP, and intervention integration into supportive and tailored services. CONCLUSIONS: Through the course of these FGDs, PrEP became a positive and highly anticipated prevention option among the FSWs participants who endorsed implementation in their communities. Effective integration of PrEP into existing services will include comprehensive health programming where ART is also available, appropriate messaging, and support. PMID- 29457870 TI - Effect of the flow profile on separation efficiency in pressure-assisted reversed polarity capillary zone electrophoresis of anions: Simulation and experimental evaluation. AB - Capillary electrophoresis connected to electrospray ionization mass spectrometry is a promising combination to analyze complex biological samples. The use of sheathless electrospray ionization interfaces, such as a porous nanoelectrospray capillary emitter, requires the application of forward flow (either by pressure or electroosmosis) to maintain the electrospray process. The analysis of solute molecules with strong negative charges (e.g., aminopyrenetrisulfonate labeled glycans) necessitates a reversed-polarity capillary electrophoresis separation mode, in which case the electroosmotic flow is counter current, thus pressure assistance is necessary. In this study, we compared the effect of forced convection with and without counter electroosmotic flow on the resulting separation efficiency in capillary electrophoresis based on flow profile simulations by computational fluid dynamics technique and by actual experiments. The efficiencies of the detected peaks were calculated from the resulting electropherograms and found approximately 950 000 plates/m for electrophoresis with counter electroosmotic flow, 20 000 plates/m with pressure only (such as would be in open tubular liquid chromatography), and 480 000 plates/m for electrophoresis with simultaneous counter electroosmotic flow and forward pressure assistance, which validates the simulation data. PMID- 29457869 TI - Assessment of the spectrum of hepatic encephalopathy: A multicenter study. AB - Hepatic encephalopathy (HE) is a major cause of morbidity in cirrhosis. However, its severity assessment is often subjective, which needs to be studied systematically. The aim was to determine how accurately trainee and nontrainee practitioners grade and manage HE patients throughout its severity. We performed a survey study using standardized simulated patient videos at 4 US and 3 Canadian centers. Participants were trainees (gastroenterology/hepatology fellows) and nontrainees (faculty, nurse practitioners, physician assistants). We determined the accuracy of HE severity identification and management options between grades <2 or >=2 HE and trainees/nontrainees. In total, 108 respondents (62 trainees, 46 nontrainees) were included. For patients with grades <2 versus >=2 HE, a higher percentage of respondents were better at correctly diagnosing grades >=2 compared with grades <2 (91% versus 64%; P < 0.001). Specialized cognitive testing was checked significantly more often in grades <2, whereas more aggressive investigation for precipitating factors was ordered in HE grades >2. Serum ammonia levels were ordered in almost a third of grade >=2 patients. For trainees and nontrainees, HE grades were identified similarly between groups. Trainees were less likely to order serum ammonia and low-protein diets, more likely to order rifaximin, and more likely to perform a more thorough workup for precipitating factors compared with nontrainee respondents. There was excellent concordance in the classification of grade >=2 HE between nontrainees versus trainees, but lower grades showed discordance. Important differences were seen regarding blood ammonia, specialized testing, and nutritional management between trainees and nontrainees. These results have important implications at the patient level, interpreting multicenter clinical trials, and in the education of practitioners. Liver Transplantation 24 587-594 2018 AASLD. PMID- 29457871 TI - A quantitative trait locus on chromosome 1 modulates intermale aggression in mice. AB - Aggression between male conspecifics is a complex social behavior that is likely modulated by multiple gene variants. In this study, the BXD recombinant inbred mouse strains (RIS) were used to map quantitative trait loci (QTLs) underlying behaviors associated with intermale aggression. Four hundred and fifty-seven males from 55 strains (including the parentals) were observed at an age of 13 +/- 1 week in a resident-intruder test following 10 days of isolation. Attack latency was measured directly within a 10-minute time period and the test was repeated 24 hours later. The variables we analyzed were the proportion of attacking males in a given strain as well as the attack latency (on days 1 and 2, and both days combined). On day 1, 29% of males attacked, and this increased to 37% on day 2. Large strain differences were obtained for all measures of aggression, indicating substantial heritability (intraclass correlations 0.10-0.18). We identified a significant QTL on chromosome (Chr) 1 and suggestive QTLs on mouse Chrs 1 and 12 for both attack and latency variables. The significant Chr 1 locus maps to a gene sparse region between 82 and 88.5 Mb with the C57BL/6J allele increasing aggression and explaining about 18% of the variance. The most likely candidate gene modulating this trait is Htr2b which encodes the serotonin 2B receptor and has been implicated in aggressive and impulsive behavior in mice, humans and other species. PMID- 29457872 TI - Simple method for the determination of personal care product ingredients in lettuce by ultrasound-assisted extraction combined with solid-phase microextraction followed by GC-MS. AB - A simple method for the simultaneous determination of personal care product ingredients: galaxolide, tonalide, oxybenzone, 4-methylbenzyliden camphor, padimate-o, 2-ethylhexyl methoxycinnamate, octocrylene, triclosan, and methyl triclosan in lettuce by ultrasound-assisted extraction combined with solid-phase microextraction followed by gas chromatography with mass spectrometry was developed. Lettuce was directly extracted by ultrasound-assisted extraction with methanol, this extract was combined with water, extracted by solid-phase microextraction in immersion mode, and analyzed by gas chromatography with mass spectrometry. Good linear relationships (25-250 ng/g, R2 > 0.9702) and low detection limits (1.0-25 ng/g) were obtained for analytes along with acceptable precision for almost all analytes (RSDs < 20%). The validated method was applied for the determination of personal care product ingredients in commercial lettuce and lettuces grown in soil and irrigated with the analytes, identifying the target analytes in leaves and roots of the latter. This procedure is a miniaturized and environmentally friendly proposal which can be a useful tool for quality analysis in lettuce. PMID- 29457873 TI - The impact of video nasal endoscopy on patient satisfaction. AB - BACKGROUND: Video nasal endoscopy has significant associated expense for practices, but its use has been justified by the benefit it provides to the examiner. No study has examined the perceived benefit to the patient. In this study, the impact of video endoscopy on patient satisfaction is evaluated. METHODS: A prospective, randomized, single-blinded study was performed on new patients receiving care in the rhinology clinics of a tertiary-care center. Patients were randomized into the standard endoscopic examination (SEE) or video endoscopic examination (VEE) groups. SEE patients had their examination performed with the physician viewing the exam through the eyepiece, without a video camera, and subsequently had their examination explained. VEE patients had their examination performed with a video camera attached to the scope, recorded, and then used for the explanation. All patients were asked to complete the 22-item Sino-Nasal Outcome Test (SNOT-22) and the 18-item Patient Satisfaction Questionnaire Short-Form (PSQ-18). Statistical analysis was performed to identify differences between cohorts. RESULTS: There was no significant demographic difference between groups. SNOT-22 total and domain scores were similar between both groups (p > 0.05). VEE patients had significantly higher general satisfaction (p = 0.048) and communication (p = 0.028) domains within the PSQ-18. There was no difference between other domains (p > 0.05). CONCLUSION: VEE is a valuable tool for otolaryngologists and patients. Further studies evaluating variance in patient compliance and symptomatology may provide further justification for its use. PMID- 29457874 TI - Computed tomography analysis of frontal cell prevalence according to the International Frontal Sinus Anatomy Classification. AB - BACKGROUND: The International Frontal Sinus Anatomy Classification (IFAC) is an international consensus document published in 2016 to standardize the nomenclature of cells in the region of the frontal recess and frontal sinus. The IFAC was designed to be surgically relevant and anatomically precise. The current study was undertaken to assess the prevalence of the frontal cell variants as defined by the IFAC, as well as to determine the interrater reliability of the IFAC. METHODS: Three independent reviewers examined triplanar nondiseased maxillofacial computed tomography (CT) scans to assess the anatomy of the frontal recess according to the IFAC system. The prevalence of each cell type was assessed and interrater reliability was measured using an intraclass correlation coefficient (ICC). RESULTS: One hundred CT scans (200 sides) were examined. Of the 200 sides, 96.5% contained an agger nasi cell (ICC, 0.82; 95% confidence interval [CI], 0.77-0.86), 30.0% contained a supra agger cell (ICC, 0.89; 95% CI, 0.86-0.92), 20.0% contained a supra agger frontal cell (ICC 0.80; 95% CI 0.74 0.84), 72.0% contained a supra bulla cell (ICC, 0.81; 95% CI, 0.76-0.85), 5.5% contained a supra bulla frontal cell (ICC, 0.71; 95% CI, 0.63-0.77), 28.5% contained a supraorbital ethmoid cell (ICC, 0.78; 95% CI, 0.72-0.83), and 30.0% contained a frontal septal cell (ICC, 0.80; 95% CI, 0.74-0.84). The ICC was good to excellent for identification of all frontal cell types. CONCLUSIONS: This study describes the normative distribution of frontal recess cells in a nondiseased population according to IFAC and demonstrates favorable interrater reliability of the classification system. PMID- 29457875 TI - Variations of the Circle of Willis at the End of the Human Embryonic Period. AB - Variations of the circle of Willis (CW) influence blood supply to the brain and adjacent structures in adults. We examined the formation of the CW in 20 human embryo samples at the end of the embryonic period using 3-D reconstructions of serial histological sections. The CW was closed in all samples, and did not form in a single plane, but was composed of multiple stair-like planes. The artery acutely curved at the caudal part of the CW, namely, at the inlet of the basilar artery and bifurcation of the P1 segment of the posterior cerebral artery (PCA), reflecting flexure of the mesencephalon and diencephalon at this stage. Variations were observed in 17 of 20 samples-only anterior parts (anterior communicating artery [Acom] and anterior cerebral artery [ACA]) in 10 samples, only posterior parts (posterior communicating artery [Pcom]) in one sample, and both anterior and posterior parts in six samples. Variations included the Acom formed as partially duplicated in three samples, duplicated in four, plexiform in three, and no channel as a result of a single azygos ACA in one. The ACA formed as duplicated in two, median ACA in two, and right hypoplasia in one. The Pcom formed in hypoplasia of either side in six samples. Variations observed in this study are similar to those observed in fetuses, neonates, and adults. The P1 segment of PCA was very large in all samples. The present observations indicate that variations in the CW are present from the initiation of CW formation. Anat Rec, 2018. (c) 2018 Wiley Periodicals, Inc. PMID- 29457876 TI - Pharmacokinetics of metformin in patients with gastrointestinal intolerance. AB - AIMS: To assess potential causes of metformin intolerance, including altered metformin uptake from the intestine, increased anaerobic glucose utilization and subsequent lactate production, altered serotonin uptake, and altered bile acid pool. METHODS: For this pharmacokinetic study, we recruited 10 severely intolerant and 10 tolerant individuals, matched for age, sex and body mass index. A single 500-mg dose of metformin was administered, with blood sampling at 12 time points over 24 hours. Blood samples were analysed for metformin, lactate, serotonin and bile acid concentrations, and compared across the phenotypes. RESULTS: The intolerant individuals were severely intolerant to 500 mg metformin. No significant difference was identified between tolerant and intolerant cohorts in metformin pharmacokinetics: median (interquartile range [IQR]) peak concentration 2.1 (1.7-2.3) mg/L and 2.0 (1.8-2.2) mg/L, respectively (P = .76); time to peak concentration 2.5 hours; median (IQR) area under the curve (AUC)0-24 16.9 (13.9-18.6) and 13.9 (12.9-16.8) mg/L*h, respectively (P = .72). Lactate concentration peaked at 3.5 hours, with mean peak concentration of 2.4 mmol/L in both cohorts (95% CI 2.0-2.8 and 1.8-3.0 mmol/L, respectively), and similar incremental AUC0-24 in each cohort: tolerant cohort 6.98 (95% CI 3.03-10.93) and intolerant cohort 4.47 (95% CI -3.12-12.06) mmol/L*h (P = .55). Neither serotonin nor bile acid concentrations were significantly different. CONCLUSIONS: Despite evidence of severe intolerance in our cohort, there was no significant difference in metformin pharmacokinetics or systemic measures of lactate, serotonin or bile acids. This suggests that metformin intolerance may be attributable to local factors within the lumen or enterocyte. PMID- 29457878 TI - Genetic determinants of heart failure: facts and numbers. AB - The relevance of gene mutations leading to heart diseases and hence heart failure has become evident. The risk for and the course of heart failure depends on genomic variants and mutations underlying the so-called genetic predisposition. Genetic contribution to heart failure is highly heterogenous and complex. For any patient with a likely inherited heart failure syndrome, genetic counselling is recommended and important. In the last few years, novel sequencing technologies (named next-generation sequencing - NGS) have dramatically improved the availability of molecular testing, the efficiency of genetic analyses, and moreover reduced the cost for genetic testing. Due to this development, genetic testing has become increasingly accessible and NGS-based sequencing is now applied in clinical routine diagnostics. One of the most common reasons of heart failure are cardiomyopathies such as the dilated or the hypertrophic cardiomyopathy. Nearly 100 disease-associated genes have been identified for cardiomyopathies. The knowledge of a pathogenic mutation can be used for genetic counselling, risk and prognosis determination, therapy guidance and hence for a more effective treatment. Besides, family cascade screening for a known familial, pathogenic mutation can lead to an early diagnosis in affected individuals. At that timepoint, a preventative intervention could be used to avoid or delay disease onset or delay disease progression. Understanding the cellular basis of genetic heart failure syndromes in more detail may provide new insights into the molecular biology of physiological and impaired cardiac (cell) function. As our understanding of the molecular and genetic pathophysiology of heart failure will increase, this might help to identify novel therapeutic targets and may lead to the development of new and specific treatment options in patients with heart failure. PMID- 29457879 TI - The good, the bad, and the ugly of luminex donor-specific crossmatch. AB - The presence of donor-specific antibodies directed against human leukocyte antigen significantly influences renal transplant because of antibody-mediated rejection. We performed the screening of pre-renal transplant patients for preformed anti-HLA antibodies using anti-human globulin augmented-complement dependent lymphocytotoxicity crossmatch (AHG-CDCXm), luminex donor-specific crossmatch (LumXm) and HLA antibody screening. Seven hundred and fifty-four patients were assessed for LumXm. HLA antibody screening was possible in 325 out of 754 cases. All the three investigations viz. CDCXm, HLA antibody screening and LumXm was performed in 325 patients. All CDCXm positive patients (10/325, 3.08%) were also positive with LumXm and HLA antibody screen whereas 14 cases (4.31%) with CDCXm negative were positive with luminex-based assays. LumXm and HLA antibody screening were both positive in 24 (7.38%) cases, LumXm and HLA antibody screening were both negative in 275 (84.63%) cases and LumXm negative and HLA antibody screening was positive in 22 (6.76%) cases. However, there were four cases (1.23%) which were positive in LumXm in spite of being negative in HLA antibody testing. Single Antigen Bead (SAB) assay was performed in all patients positive for HLA antibody test. We suggest that LumXm is a useful and sensitive technique for the detection of anti-HLA antibodies in pre-transplant renal patients. However, other measures such as luminex antibody screen, SAB assay, history of the donor, and the class of antibodies involved should be taken into consideration for pre-transplant work up of renal patients.

PMID- 29457883 TI - Mapping the H-NOX/HK Binding Interface in Vibrio cholerae by Hydrogen/Deuterium Exchange Mass Spectrometry. AB - Heme-nitric oxide/oxygen binding (H-NOX) proteins are a group of hemoproteins that bind diatomic gas ligands such as nitric oxide (NO) and oxygen (O2). H-NOX proteins typically regulate histidine kinases (HK) located within the same operon. It has been reported that NO-bound H-NOXs inhibit cognate histidine kinase autophosphorylation in bacterial H-NOX/HK complexes; however, a detailed mechanism of NO-mediated regulation of the H-NOX/HK activity remains unknown. In this study, the binding interface of Vibrio cholerae ( Vc) H-NOX/HK complex was characterized by hydrogen/deuterium exchange mass spectrometry (HDX-MS) and further validated by mutagenesis, leading to a new model for NO-dependent kinase inhibition. A conformational change in Vc H-NOX introduced by NO generates a new kinase-binding interface, thus locking the kinase in an inhibitory conformation. PMID- 29457884 TI - Unique Biochemical and Sequence Features Enable BluB To Destroy Flavin and Distinguish BluB from the Flavin Monooxygenase Superfamily. AB - Vitamin B12 (cobalamin) is an essential micronutrient for humans that is synthesized by only a subset of bacteria and archaea. The aerobic biosynthesis of 5,6-dimethylbenzimidazole, the lower axial ligand of cobalamin, is catalyzed by the "flavin destructase" enzyme BluB, which fragments reduced flavin mononucleotide following its reaction with oxygen to yield this ligand. BluB is similar in sequence and structure to members of the flavin oxidoreductase superfamily, yet the flavin destruction process has remained elusive. Using stopped-flow spectrophotometry, we find that the flavin destructase reaction of BluB from Sinorhizobium meliloti is initiated with canonical flavin-O2 chemistry. A C4a-peroxyflavin intermediate is rapidly formed in BluB upon reaction with O2, and has properties similar to those of flavin-dependent hydroxylases. Analysis of reaction mixtures containing flavin analogues indicates that both formation of the C4a-peroxyflavin and the subsequent destruction of the flavin to form 5,6 dimethylbenzimidazole are influenced by the electronic properties of the flavin isoalloxazine ring. The flavin destruction phase of the reaction, which results from the decay of the C4a-peroxyflavin intermediate, occurs more efficiently at pH >7.5. Furthermore, the BluB mutants D32N and S167G are specifically impaired in the flavin destruction phase of the reaction; nevertheless, both form the C4a peroxyflavin nearly quantitatively. Coupled with a phylogenetic analysis of BluB and related flavin-dependent enzymes, these results demonstrate that the BluB flavin destructase family can be identified by the presence of active site residues D32 and S167. PMID- 29457885 TI - Thienyl-Substituted alpha-Ketoamide: A Less Hydrophobic Reactive Group for Photo Affinity Labeling. AB - Photoaffinity labeling (PAL) is an important tool in chemical biology research, but application of alpha-ketoamides for PAL has been hampered by their photoinstability. Here, we show that 2-thienyl-substituted alpha-ketoamide is a superior photoreactive group for PAL. Studies with a series of synthetic mannose conjugated alpha-ketoamides revealed that 2-thienyl substitution of alpha ketoamide decreased the electrophilicity of the keto group and reduced the rate of photodegradation. Mannose-conjugated thienyl alpha-ketoamide showed greater concanavalin A labeling efficiency than other alkyl or phenyl-substituted alpha ketoamides. In comparison with representative conventional photoreactive groups, 2-thienyl ketoamide showed reduced labeling of nontarget proteins, probably owing to its lower hydrophobicity.

AB - Gradient meshes with Janus wettabilities are fabricated to stably separate and collect spilled oils from a range of flowing oily wastewater. Here, we demonstrate an overflow with separation methodology, which combines selective oil overflow and membrane separation, to separate low content oils from dynamic flowing oil-water mixtures by a curved gradient mesh that covered on a solid edge. The microscaled air-oil-water-solid four-phase wetting state during the oil water separation process is visualized and demonstrated. The fundamental understanding of this overflow with separation system and the superior gradient mesh materials would enable us to construct a wide variety of separation devices out of traditional designs and advance related applications, such as wastewater treatment and fuel purification.

PMID- 29457889 TI - Rapid Microwave Preparation and Composition Tuning of the High-Performance Magnetocalorics (Mn,Fe)2(P,Si). AB - Rapid preparation utilizing assisted microwave heating permits significantly shorter preparation times for magnetocaloric compounds in the (Mn,Fe)2(P,Si) family, specifically samples of (Mn,Fe)2-deltaP0.5Si0.5 with starting compositions of delta = 0, 0.06, and 0.12. To fully understand the effects of processing and composition changes on structure and properties, these materials are characterized using synchrotron powder diffraction, neutron powder diffraction, electron microprobe analysis (EMPA), X-ray fluorescence (XRF), and magnetic measurements. The diffraction analysis reveals that increasing delta results in decreasing amounts of the common Heusler (Mn,Fe)3Si secondary phase. EMPA shows (Mn,Fe)2(P,Si) in all three samples to be Mn and P rich, whereas XRF demonstrates that the bulk material is Mn rich yet P deficient. Increasing delta brings the Mn/Fe and P/Si ratios closer to their starting values. Measurements of magnetic properties show an increase in saturation magnetization and ordering temperature with increasing delta, consistent with the increase in Fe and Si contents. Increasing delta also results in a decrease in thermal hysteresis and an increase in magnetic entropy change, the latter reaching values close to what have been previously reported on samples that take much longer to prepare. PMID- 29457890 TI - Headspace Solid-Phase Microextraction Coupled to Miniaturized Microplasma Optical Emission Spectrometry for Detection of Mercury and Lead. AB - Despite increased interest in microplasma atomic spectrometry over the past several years, its applications to field analysis of real samples still remain limited due to its low sensitivity. In this work, headspace solid-phase microextraction (HS-SPME) using PDMS/DVB fiber was used as a sample introduction method to improve the sensitivity of a miniature (6.0 cm length * 5.0 cm width * 2.8 cm height) low power (<10 W) microplasma point discharge optical emission spectrometer (PD-OES) for the determination of Hg and Pb after their derivatization with sodium tetraethylborate (NaBEt4). Owing to its advantages of combining sampling, separation, and preconcentration of analytes from sample matrices into a single step, HS-SPME not only simplifies sample pretreatment and the experimental setup but also eliminates interferences from matrices and water vapor while significantly improving analytical performance. In comparison to photochemical vapor generation PD-OES, limits of detection for Hg and Pb were enhanced by at least 100-fold, providing great potential for field analysis of these and other trace elements in real samples. Under optimal conditions, the limits of detection for Hg and Pb were 0.001 and 0.003 MUg L-1, respectively, with relative standard deviations (RSDs) better than 2.1% and 4.5% at a concentration of 1 MUg L-1. The accuracy of the HS-SPME-PD-OES system was validated by analysis of three Certified Reference Materials, including DORM-4 (Hg, 412 +/- 36 MUg kg-1; Pb, 404 +/- 62 MUg kg-1), TORT-3 (Hg, 292 +/- 22 MUg kg 1; Pb, 225 +/- 18 MUg kg-1) and SRM1568b (Hg, 5.53 +/- 0.58 MUg kg-1), providing analytical results in excellent agreement with certified values at the 95% confidence level. This method was also successfully used for the analysis of several real rice and water samples with satisfactory results (90-130% recoveries of added spikes).

A series of enantiomerically enriched 3a-nitro-hexahydropyrrolo[2,3-b]indole and 8b nitrohexahydrocyclopenta[b]indole derivatives containing three contiguous chiral centers are smoothly obtained in high yields with satisfactory regio-, chemo-, and enantioselectivity. Remarkably, the synthetic utility of this process was demonstrated through direct reductive amination and functionalization of the carbon-carbon double bond of the desired products.

AB - Regio- and 1,2- cis-stereoselective chemical glycosylation of unprotected glycosyl acceptors has been in great demand for the efficient synthesis of natural glycosides. However, simultaneously regulating these selectivities has been a longstanding problem in synthetic organic chemistry. In nature, glycosyl transferases catalyze regioselective 1,2- cis-glycosylations via the SNi mechanism, yet no useful chemical glycosylations based on this mechanism have been developed. In this paper, we report a highly regio- and 1,2- cis stereoselective SNi-type glycosylation of 1,2-anhydro donors and unprotected sugar acceptors using p-nitrophenylboronic acid (10e) as a catalyst in the presence of water under mild conditions. Highly controlled regio- and 1,2- cis stereoselectivities were achieved via the combination of boron-mediated carbohydrate recognition and the SNi-type mechanism. Mechanistic studies using the KIEs and DFT calculations were consistent with a highly dissociative concerted SNi mechanism. This glycosylation method was applied successfully to the direct glycosylation of unprotected natural glycosides and the efficient synthesis of a complex oligosaccharide with minimal protecting groups. PMID- 29457893 TI - Kinetics, Thermodynamics, and Mechanism of a Novel Biphasic Solvent for CO2 Capture from Flue Gas. AB - The main issue related to the deployment of the amine-based absorption process for CO2 capture from flue gas is its intensive energy penalty. Therefore, this study screened a novel biphasic solvent, comprising a primary amine e.g., triethylenetetramine (TETA) and a tertiary amine e.g., N, N dimethylcyclohexylamine (DMCA), to reduce the energy consumption. The TETA-DMCA blend exhibited high cyclic capacity of CO2 absorption, favorable phase separation behavior, and low regeneration heat. Kinetic analysis showed that the gas- and liquid-side mass transfer resistances were comparable in the lean solution of TETA-DMCA at 40 degrees C, whereas the liquid-side mass transfer resistance became dominant in the rich solution. The rate of CO2 absorption into TETA-DMCA (4 M, 1:3) solution was comparable to 5 M benchmark monoethanolamine (MEA) solution. Based on a preliminary estimation, the regeneration heat with TETA-DMCA could be reduced by approximately 40% compared with that of MEA. 13C NMR analysis revealed that the CO2 absorption into TETA-DMCA was initiated by the reaction between CO2 and TETA via the zwitterion mechanism, and DMCA served as a CO2 sinker to regenerate TETA, resulting in the transfer of DMCA from the upper to lower phase. The proposed TETA-DMCA solvent may be a suitable candidate for CO2 capture. PMID- 29457894 TI - Small Molecule Allosteric Modulators of G-Protein-Coupled Receptors: Drug-Target Interactions. AB - G-protein-coupled receptors (GPCRs) are the largest class of signaling receptors that are most frequently targeted by therapeutic drugs. Allosteric modulators bound to GPCRs at allosteric sites provide the potential for differential selectivity and improved safety compared with traditional orthosteric ligands. The recent breakthroughs in GPCR structural biology have made structures of GPCRs from classes A, B, C, and F complexed with small-molecule allosteric modulators available. Knowledge of the detailed receptor-modulator interactions at the allosteric sites is useful for structure-based GPCR drug design of novel therapeutics. This Perspective comprehensively summarizes the current status of structural complexes between GPCRs and their small-molecule allosteric modulators, particularly the key receptor-modulator interactions at the allosteric sites. Then, the structural diversity of allosteric sites across four GPCR subfamilies is compared. This study is expected to contribute to the design of GPCR allosteric drugs with an improved therapeutic action. PMID- 29457895 TI - Periodic Trends in Actinyl Thio-Crown Ether Complexes. AB - In-cavity complexes and their bonding features between thio-crown (TC) ethers and f-elements are unexplored so far. In this paper, actinyl(VI) (An = U, Np, Pu, Am, and Cm) complexes of TC ethers have been characterized using relativistic density functional theory. The TC ether ligands include tetrathio-12-crown-4 (12TC4), pentathio-15-crown-5 (15TC5), and hexathio-18-crown-6 (18TC6). On the basis of the calculations, it is found that the "double-decker" sandwich structure of AnO2(12TC4)22+ and "side-on" structure AnO2(12TC4)2+ are changed to "insertion" structures for AnO2(15TC5)2+ and AnO2(18TC6)2+ due to increased size of the TC ether ligands. The actinyl monocyclic TC ether complexes are found to exhibit conventional conformations, with typical An-Oactinyl and An-Sligand distances and angles. Chemical bonding analyses by Weinhold's natural population analysis (NPA), natural localized molecular orbital (NLMO), and energy decomposed analysis (EDA), show that a typical ionic An-Sligand bond with the extent of covalent interaction between the An and S atoms primarily attributable to the degree of radial distribution of the S 3p atomic orbitals. The similarity and difference of the oxo-crown and TC ethers as ligands for actinide coordination chemistry are discussed. As soft S-donor ligands, TC ethers may be candidate ligands for actinide recognition and extraction. PMID- 29457896 TI - Nature of the Color of Borates with "Anti-Zeolite" Structure. AB - Crystals of the Mn xBa12(BO3)8-2 xF8 x phase were grown from a high-temperature solution. This new fluoride borate is built of positively charged [Ba12(BO3)6]6+ blocks, the so-called "anti-zeolite" pattern. Using X-ray single-crystal diffraction, the bulk atomic arrangement in the centrosymmetric tetragonal unit cell in I4/ mcm could be elucidated. Crystals of the (MnF6)4- group-containing solid solution Mn xBa12(BO3)8-2 xF8 x are dark brown in color in contrast to the differently colored crystals of (LiF4)3- group-containing "anti-zeolite" LiBa12(BO3)7F4 ( P42 bc). According to the electron spin resonance and optical spectroscopic investigation, the absorption spectrum of LiBa12(BO3)7F4 crystals results from the absorption of light by both exciton and free charge carriers and can be tuned by varying the initial composition of the high-temperature solution. PMID- 29457897 TI - Macrocyclic Oligofurans: A Computational Study. AB - Macrocyclic oligothiophenes ( nCT) have been extensively explored for their unique optical and electronic properties, while their oxygen-containing analogues, macrocyclic oligofurans ( nCF), are not known. In this work, macrocyclic oligofurans bearing 5-16 units (5CF-16CF) are studied theoretically at the B3LYP/6-311G(d) level. We find that small macrocycles (6CF-8CF) exhibit planar or nearly planar geometries, low strain energies, low HOMO-LUMO gaps, and strong pi-conjugation as also reflected in their Raman spectra. These findings are in sharp contrast to macrocyclic oligothiophenes of the same size, which are distorted from planarity. Additionally, small macrocyclic furans display significantly lower reorganization energies and ionization potentials compared with their thiophene analogues. Overall, the observed properties highlight the potential of macrocyclic oligofurans to function as p-type organic electronic materials.

AB - The aryloxy triester phosphoramidate prodrug approach has been used with success in drug discovery. Herein, we describe the first application of this prodrug technology to the monophosphate derivative of the phosphoantigen HMBPP and one of its analogues. Some of these prodrugs exhibited specific and potent activation of Vgamma9/Vdelta2 T-cells, which were then able to lyse bladder cancer cells in vitro. This work highlights the promise of this prodrug technology in the discovery of novel immunotherapeutics.

AB - A selective mono-/tetraacetoxylation of o-carboranes with acetic acid via cross dehydrogenative coupling of cage B-H/O-H bonds has been developed, and a series of mono- and tetraacetoxylated o-carboranes have been synthesized with moderate to good yields as well as good selectivity. Mechanistic studies indicate that the acetoxyl originates from acetic acid directly, and a nucleophilic addition of PdIV-oxo species and dehydration process is proposed.

AB - A new deep-blue chromophore containing a three-dimensionally (3D) shaped CS core composed of fused chrysene and spirofluorene units is synthesized. A pair of m terphenyl (TP) units is also substituted onto the CS core at two different sets of positions to form two additional compounds: CS-TPTP and TP-CS-TP. The TP-CS-TP compound showed the highest efficiency with an external quantum efficiency (EQE) of 3.05% and Commission Internationale de L'Eclairage coordinates (CIE) of (0.148, 0.098) corresponding to the emission of blue light. This approach for forming a new chromophore is expected to lead to the development of functional organic materials with excellent characteristics.

AB - An efficient base-promoted C(sp3)-H bond functionalization strategy for the synthesis of multisubstituted chromans from the formal [3+3] cycloaddition of benzo[c]oxepines and electron-rich phenols has been developed. The corresponding 4H-chromenes can be easily obtained in excellent yields by simple filtration from chromans. Preliminary mechanistic studies indicate that the C-O bond cleavage is the key step for the C(sp3)-H bond functionalization and that this reaction could have occurred through tandem C-O bond cleavage/Michael addition/annulation reactions.

AB - We report a series of thermally activated delayed fluorescence (TADF) molecules with mechanochromic luminescence properties and reversible TADF turn on/off properties in solid state that are induced by the transition between amorphous and crystalline states. Additionally, multicolor altering through external stimulus is demonstrated. All of the studied compounds exhibited recovery of the initial states associated with narrower emission spectra. TADF organic light emitting diodes fabricated by solution processing rendered high external quantum efficiency up to 10.9% and luminance of 16 760 cd m-2. PMID- 29457903 TI - Excited-State Proton Transfer in 3-Cyano-7-azaindole: From Aqueous Solution to Ice. AB - We investigated the excited-state proton transfer (ESPT) reaction for 3-cyano-7 azaindole (3CAI) in aqueous solution and in ice. 3CAI undergoes water-catalyzed ESPT in the aqueous solution, giving normal (355 nm) and proton transfer tautomer (~472 nm) emission bands. Detailed temperature-dependent studies showed that the values of activation free energy (Delta G?) were similar between N-H and N-D isotopes. Therefore, water-catalyzed ESPT involves a stepwise mechanism incorporating solvation equilibrium ( Keq) to form a 1:1 (molar ratio) water:3CAI cyclic hydrogen-bonded complex as an intermediate, followed by perhaps proton tunneling reaction. In sharp contrast, 3CAI in ice undergoes entirely different photophysical properties, in which 3CAI self-organizes to form a double-hydrogen bonded dimers at the grain boundary of the polycrystalline. Upon excitation, the dimer proceeds with a fast excited-state double proton transfer reaction, giving rise to solely a tautomer emission (~450 nm). The distinct difference in ESPT properties between water and ice makes azaindoles feasible for the investigation of water-ice interface property. PMID- 29457904 TI - Conflict in the Mechanism and Kinetics of the Barrierless Reaction between SH and NO2 Radicals. AB - There are some unsettled issues regarding the mechanism and kinetics of an important atmospheric reaction of NO2 radical with the SH radical. The existing mechanism is based on the formation of HSO and NO radicals, both of which can result only along one barrierless channel. However, the detection of NO radical has never been reported though the formation of HSO radical has been followed in some studies to determine the rate constants. The latter are mainly obtained by monitoring the SH decay, but rate constants are reported to be highly conflicting among the existing studies reporting its value ranging from 10-10 to 10-12 cm3 molecule-1 sec-1. The present work attempts to resolve these issues by exploring various reaction pathways through the global reaction route mapping of the potential energy surface at the level of spin-unrestricted and spin-restricted coupled-cluster and density functional theories. The initial association of two radicals was found to proceed via two barrierless modes: (1) S-N association leading to HSNO2 and, (2) S-O association resulting in HSONO, in particular the cis-isomer. The kinetics of the barrierless pathways was investigated through rate constants computed using canonical variational transition state theory (CVTST) along with their temperature and pressure dependence investigated using the master equation. The rate constants calculated using spin-unrestricted methods are found to be in agreement with experimentally observed range of rate constant, and the formation of cis-HSONO (via mode 2) is observed to be the main contributing channel. Contrary to the results of spin-restricted calculations, the barrierless channel (mode 1) leading to the formation of HSNO2 is predicted to involve two bottlenecks when results using spin-unrestricted calculations were analyzed. Notably, the spin-unrestricted calculations predict a prereaction complex for the formation of S-N bond (via mode 1) which has been treated using Miller's unified transition state theory with a two transition state model. The fate of all the species involved in the reaction is critically evaluated in the present work, and the predictions made can be a subject of further experimental and theoretical studies involving radical-radical reactions. PMID- 29457905 TI - Computational Investigation of the Influence of Halogen Atoms on the Photophysical Properties of Tetraphenylporphyrin and Its Zinc(II) Complexes. AB - How the tetraphenylporphyrin (TPP) and its zinc(II) complexes (ZnTPP) photophysical properties (absorption energies, singlet-triplet energy gap and spin-orbit coupling contributions) can change due to the presence of an increasing number of heavy atoms in their molecular structures has been investigated by means of density functional theory and its time-dependent formulation. Results show that the increase of the atomic mass of the substituted halogen strongly enhances the spin-orbit coupling values, allowing a more efficient singlet-triplet intersystem crossing. Different deactivation channels have been considered and rationalized on the basis of El-Sayed and Kasha rules. Most of the studied compounds possess the appropriate properties to generate cytotoxic singlet molecular oxygen (1Deltag) and, consequently, they can be proposed as photosensitizers in photodynamic therapy. PMID- 29457907 TI - Deletion of Adipose Triglyceride Lipase Links Triacylglycerol Accumulation to a More-Aggressive Phenotype in A549 Lung Carcinoma Cells. AB - Adipose triglyceride lipase (ATGL) catalyzes the rate limiting step in triacylglycerol breakdown in adipocytes but is expressed in most tissues. The enzyme was shown to be lost in many human tumors, and its loss may play a role in early stages of cancer development. Here, we report that loss of ATGL supports a more-aggressive cancer phenotype in a model system in which ATGL was deleted in A549 lung cancer cells by CRISPR/Cas9. We observed that loss of ATGL led to triacylglycerol accumulation in lipid droplets and higher levels of cellular phospholipid and bioactive lipid species (lyso- and ether-phospholipids). Label free quantitative proteomics revealed elevated expression of the pro-oncogene SRC kinase in ATGL depleted cells, which was also found on mRNA level and confirmed on protein level by Western blot. Consistently, higher expression of phosphorylated (active) SRC (Y416 phospho-SRC) was observed in ATGL-KO cells. Cells depleted of ATGL migrated faster, which was dependent on SRC kinase activity. We propose that loss of ATGL may thus increase cancer aggressiveness by activation of pro-oncogenic signaling via SRC kinase and increased levels of bioactive lipids. PMID- 29457906 TI - Optimized Phenotypic Biomarker Discovery and Confounder Elimination via Covariate Adjusted Projection to Latent Structures from Metabolic Spectroscopy Data. AB - Metabolism is altered by genetics, diet, disease status, environment, and many other factors. Modeling either one of these is often done without considering the effects of the other covariates. Attributing differences in metabolic profile to one of these factors needs to be done while controlling for the metabolic influence of the rest. We describe here a data analysis framework and novel confounder-adjustment algorithm for multivariate analysis of metabolic profiling data. Using simulated data, we show that similar numbers of true associations and significantly less false positives are found compared to other commonly used methods. Covariate-adjusted projections to latent structures (CA-PLS) are exemplified here using a large-scale metabolic phenotyping study of two Chinese populations at different risks for cardiovascular disease. Using CA-PLS, we find that some previously reported differences are actually associated with external factors and discover a number of previously unreported biomarkers linked to different metabolic pathways. CA-PLS can be applied to any multivariate data where confounding may be an issue and the confounder-adjustment procedure is translatable to other multivariate regression techniques. PMID- 29457908 TI - Process Proteomics of Beer Reveals a Dynamic Proteome with Extensive Modifications. AB - Modern beer production is a complex industrial process. However, some of its biochemical details remain unclear. Using mass spectrometry proteomics, we have performed a global untargeted analysis of the proteins present across time during nanoscale beer production. Samples included sweet wort produced by a high temperature infusion mash, hopped wort, and bright beer. This analysis identified over 200 unique proteins from barley and yeast, emphasizing the complexity of the process and product. We then used data independent SWATH-MS to quantitatively compare the relative abundance of these proteins throughout the process. This identified large and significant changes in the proteome at each process step. These changes described enrichment of proteins by their biophysical properties, and identified the appearance of dominant yeast proteins during fermentation. Altered levels of malt modification also quantitatively changed the proteomes throughout the process. Detailed inspection of the proteomic data revealed that many proteins were modified by protease digestion, glycation, or oxidation during the processing steps. This work demonstrates the opportunities offered by modern mass spectrometry proteomics in understanding the ancient process of beer production. PMID- 29457909 TI - Droplet Translation Actuated by Photoelectrowetting. AB - In traditional electrowetting-on-dielectric (EWOD) devices, droplets are moved about a substrate using electric fields produced by an array of discrete electrodes. In this study, we show that a drop can be driven across a substrate with a localized light beam by exploiting the photoelectrowetting (PEW) effect, a light-activated variant of EWOD. Droplet transport actuated by PEW eliminates the need for electrode arrays and the complexities entailed in their fabrication and control, and offers a new approach for designing lab-on-a-chip applications. We report measurements of the maximum droplet speed as a function of frequency and magnitude of the applied bias, intensity of illumination, volume of the droplet, and viscosity and also introduce a model that reproduces these data. PMID- 29457910 TI - Mechanistic Analysis of Ion Association between Dendrigraft Poly-l-lysine and 8 Anilino-1-naphthalenesulfonate at Liquid|Liquid Interfaces. AB - Molecular association between biocompatible dendritic polymers, dendrigraft poly l-lysines (DGLs), and an anionic fluorescent probe, 8-anilino-1 naphthalenesulfonate (ANS-), was studied at the polarized water|1,2 dichloroethane (DCE) interface. The fluorescence intensity of ANS measured in aqueous solution was enhanced by the coexistence of DGLs over a wide pH range (2 < pH < 10), where ANS and DGL exist as a monoanionic form and a polycation, respectively. The voltammetric responses indicated that the positively charged DGLs were adsorbed at the water|DCE interface, whereas ANS- was transferred across the interface accompanied by the adsorption process. The interfacial behavior of the DGL-ANS associates was analyzed by potential-modulated fluorescence (PMF) spectroscopy. The PMF results demonstrated that the ion association between DGLs and ANS at the water|DCE interface is strongly affected by the applied potential and the dendritic generation of DGL. By applying appropriate potentials, the ANS anion was dissociated from its ion associate with DGLs at the interface and transferred into the organic phase, whereas DGLs remained in the aqueous phase. The Gibbs free energy of ion association (Delta GD...ANS) was estimated for the second-fourth generation DGLs (DGL-G2-G4) and the G4 polyamidoamine (PAMAM) dendrimer as a control. The highest stability of the DGL-G4-ANS associate manifested itself through Delta GD...ANS: DGL-G4-ANS (>G4 PAMAM dendrimer-ANS) > DGL-G3-ANS > DGL-G2-ANS. The results elucidated the efficient anion-binding ability of higher generation DGLs and its potential dependence at the liquid|liquid interface.

AB - Manganese-catalyzed C2-H enaminylation of 1-(pyrimidin-2-yl)-1H-indoles with ketenimines is reported. The reaction provided 2-enaminylated indole derivatives in moderate to excellent yields with a broad substrate scope. A migration of the directing group pyrimidinyl occurred during this process.

PMID- 29457912 TI - Decreased resting gamma activity in adult attention deficit/hyperactivity disorder. AB - OBJECTIVES: To delineate task-free gamma activity in adult ADHD and healthy control subjects based on high-density EEG recordings. Relationship of gamma activity with symptom severity was also examined, since gamma activity is considered to be an index of network functions in the brain that underlie higher order cognitive processes. METHODS: Spontaneous EEG was recorded in adult ADHD subjects (N = 42; 25 methylphenidate-naive and 17 on methylphenidate treatment) and controls (N = 59) with eyes open. EEG absolute power gamma was investigated in the gamma1 (30.25-39 Hz) and gamma2 (39.25-48 Hz) frequency bands. RESULTS: Gamma1 and gamma2 activity was diminished in ADHD compared with healthy control subjects. The difference between ADHD and controls was the most pronounced in the right centroparietal region for both gamma1 and gamma2. Inverse associations were found between gamma1 and gamma2 activity and ADHD symptoms in centroparietal scalp regions. CONCLUSIONS: Gamma activity is reduced in adult ADHD, and the reduction has a predominantly right centroparietal distribution. Our findings are consistent with childhood ADHD literature with respect to diminished posterior gamma activity in patients, which may reflect altered dorsal attention network functions. Gamma abnormalities might provide a link between neurophysiological functioning and neuropsychological deficiencies, thereby offering an opportunity to investigate the neurobiological mechanisms that underlie the clinical symptoms of ADHD. PMID- 29457913 TI - Light emitting diode irradiation induced shape conversion of DNA-capped silver nanoparticles and their antioxidant and antibacterial activities. AB - Due to size- and shape-dependent properties, a shape-controlled synthesis of silver nanoparticles (AgNPs) is one of the research challenging topics for their production and potential applications. This work reported the simple eco-friendly syntheses of different shaped AgNPs controlled by the plasmid DNA content and light emitting diodes (LEDs) irradiation. The synthesized AgNPs appeared as yellow, orange and green colloidal AgNPs, which transmission electron microscope (TEM) images revealed their different shapes; spherical AgNPs, a mixture of spherical and hexagonal AgNPs, and a mixture of spherical, hexagonal and corner truncated triangle AgNPs, respectively. The average sizes of spherical, hexagonal and corner-truncated triangle AgNPs in the green colloidal solution were 12.32 +/ 2.22, 23.03 +/- 6.62 and 15.84 +/- 4.31 nm, respectively. The analyses of X-ray diffraction, selected area electron diffraction and high-resolution TEM indicated the crystalline nature of the synthesized particles as the face-centred cubic silver. All synthesized AgNPs exhibited antioxidant activities similarly, whereas the yellow colloidal AgNPs exhibited the strongest antibacterial activity against both Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus as compared with the green and orange colloidal AgNPs. PMID- 29457914 TI - Estimating road traffic injuries in Jinja district, Uganda, using the capture recapture method. AB - Road traffic injuries (RTIs) are commonly under-reported in low-and-medium-income countries. This study aimed to estimate the number of RTIs and determine the magnitude of under-reporting by traffic police and hospital registries. A two source capture-recapture method was applied to RTI data from police and hospital registries. Seven matching variables; sex of the injured, date, place, time, day of crash and road user type were used to get the matched cases. Police independently reported 46 RTIs and the hospitals reported 206 RTIs. Using the capture-recapture analysis, both sources estimated 313 RTIs (95% CI 273-343). The police registry captured 14.4% of the estimated number of RTIs and the hospitals captured 60.4%. The estimated number of RTIs was higher than reported by either the police or the hospitals alone. Neither the police nor the hospitals provided accurate data on RTIs, calling for the strengthening of both sources of data. PMID- 29457915 TI - How good are we at selecting students that meet our mission? Outcomes of the 2011 and 2012 entering classes selected by a locally developed multiple mini interview. AB - BACKGROUND: Can a locally developed multiple mini interview (MMI) process lead to outcomes reflective of local values and mission? METHODS: In 2017, the authors performed a retrospective analysis of the relationship of MMI with multiple choice-based outcomes and non-multiple-choice-based outcomes, including clerkship competencies, OSCE, scholarship/service/leadership, academic honor society induction, peer and faculty humanism nominations, and overall performance at graduation for two entering classes with acceptance decisions based exclusively on a locally developed MMI. RESULTS: There was no association between MMI and performance on multiple-choice-based examinations. For other outcomes, the effect size of MMI for OSCE was small and leadership/service and scholarship did not correlate with MMI score. For clerkship competencies, there was medium effect size for patient care, practice-based learning and improvement, interpersonal and communication skills, and cultural competence. Highest and lowest quartile MMI scorers were no different in academic honor society induction; however, top quartile MMI scorers received more humanism votes versus last quartile and were more likely rated outstanding or excellent graduates. CONCLUSIONS: Local development of MMI and of admissions processes with sole reliance on MMI for final acceptance decisions will not affect academic preparation/medical school performance in multiple-choice-based assessments but can lead to locally desired attributes in students. PMID- 29457916 TI - Systematic review of psychiatric signs in Niemann-Pick disease type C. AB - OBJECTIVES: We conducted the first systematic literature review and analysis of psychiatric manifestations in Niemann-Pick disease type C (NPC) to describe: (1) time of occurrence of psychiatric manifestations relative to other disease manifestations; and (2) frequent combinations of psychiatric, neurological and visceral disease manifestations. METHODS: A systematic EMBase literature search was conducted to identify, collate and analyze published data from patients with NPC associated with psychiatric symptoms, published between January 1967 and November 2015. RESULTS: Of 152 identified publications 40 were included after screening that contained useable data from 58 NPC patients (mean [SD] age at diagnosis of NPC 27.8 [15.1] years). Among patients with available data, cognitive, memory and instrumental impairments were most frequent (90% of patients), followed by psychosis (62%), altered behavior (52%) and mood disorders (38%). Psychiatric manifestations were reported before or at neurological disease onset in 41 (76%) patients; organic signs (e.g., hepatosplenomegaly, hearing problems) were reported before psychiatric manifestations in 12 (22%). Substantial delays to diagnosis were observed (5-6 years between psychiatric presentation and NPC diagnosis). CONCLUSIONS: NPC should be considered as a possible cause of psychiatric manifestations in patients with an atypical disease course, acute-onset psychosis, treatment failure, and/or certain combinations of psychiatric/neurological/visceral symptoms. PMID- 29457917 TI - Clinical characteristics and long-term prognosis of elderly-onset Crohn's disease. AB - OBJECTIVES: This study aimed to evaluate the clinical characteristics and clinical course of Asian elderly-onset Crohn's disease (EOCD) patients in a large well-defined cohort of South Korean IBD patients. MATERIALS AND METHODS: From the Asan inflammatory bowel disease registry, we identified 29 EOCD patients (diagnosed with CD in age of 60 years or over) out of 2989 CD patients (1.0%). After excluding two patients with unclear data, 27 EOCD were matched with 108 young-onset CD (YOCD) and 108 middle age-onset CD (MOCD) for the interval from symptom onset to diagnosis (+/-3 years) and follow-up duration (+/-3 years). RESULTS: Females were predominant in the EOCD group (59.3%) compared to MOCD (31.5%) and YOCD (29.6%) groups (p = .012). In EOCD group, terminal ileal location was the most common (63.0%) at diagnosis, whereas ileocolonic location in other groups (57.4% in MOCD and 78.7% in YOCD, respectively) (p < .001). Patients with perianal fistula at CD diagnosis were less common (14.8% in EOCD vs. 28.7% in MOCD vs. 49.1% in YOCD, p < .001). During follow-up, thiopurines were used less frequently in the EOCD group (48.1% in EOCD vs. 87.0% in MOCD vs. 89.8% in YOCD, p < .001), but the risk for intestinal resection was comparable among three groups (p = .583). CONCLUSIONS: EOCD may have a better clinical course than MOCD and YOCD, as demonstrated by the similar risk for intestinal resection despite the less frequent use of thiopurines. PMID- 29457918 TI - Quality of life among patients during subacute phase following stroke during hospitalisation period in Shanghai. AB - OBJECTIVE: This study aimed to investigate the factors influencing the quality of life of in-hospital subacute stroke patients. METHODS: The patients of subacute stroke (within four weeks) in our institution between 2015 and 2016 were recruited. Patients' characteristics and QOL were obtained from medical charts and stroke-specific quality of life scale (SS-QOL). Associations of each domain in SS-QOL with socio-demographic, clinical factors and patient satisfaction were investigated using the linear regression models. RESULTS: Among the 203 subjects, 60 were diagnosed as large artery atherosclerosis (LAA), 80 were small-artery occlusion (SAO), 28 were cardioembolism (CE) and 35 were intracranial haemorrhage (ICH). The ICH group had the worst self-care ability and upper extremity function. Worse severity of stroke was associated with lower levels of language ability, mobility, mood status and upper-extremity function. Participants who had better satisfaction had high levels of capability of conducting family roles, positive emotions, personality consistency, self-care ability and capacity of conducting social roles. CONCLUSIONS: The level of patient satisfaction, duration of hospitalisation and the severity of stroke were found to be the three important factors associated with SS-QOL at hospital discharge, indicating doctors might assist patients adjust to the consequences of stroke and improve the QOL of subacute stroke.

In this study, we compared the microbiological quality of ready-to-eat (RTE) foods found in community canteens versus hospital canteens in Rome, Italy, focusing on detection and quantification of Enterobacteriaceae and the antibiotic resistance of these bacteria. Our findings show a remarkable difference in Enterobacteriaceae contamination between RTE foods distributed in community canteens (33.5% of samples) and those distributed in hospital canteens (5.3% of samples). This result highlights greater attention to good manufacturing practices and good hygiene practices by the food operators in hospitals compared with food operators in community canteens. As expected, a higher percentage of cold food samples (70.9%) than of hot food samples (10.8%) were positive for these bacteria. Excluding the intrinsic resistance of each bacterial strain, 92.3% of the isolated strains were resistant to at least one antibiotic, and about half of the isolated strains were classified as multidrug resistant. The prevalence of multidrug-resistant strains was 50% in the community samples and 33.3% in hospital canteens. Our results indicate that approximately 38% of RTE foods provided in community canteens is not compliant with microbiological food safety criteria and could be a special risk for consumers through spread of antibiotic-resistant strains. Hygienic processing and handling of foods is necessary for both hospital and community canteens. PMID- 29457920 TI - A critical appraisal of the reporting quality of published randomized controlled trials in the fall injuries. AB - To evaluate the quality of reporting in published randomized controlled trials (RTCs) in the field of fall injuries. The 188 RTCs published between 2001 and 2011, indexed in EMBASE and Medline databases were extracted through searching by appropriate keywords and EMTree classification terms. The evaluation trustworthiness was assured through parallel evaluations of two experts in epidemiology and biostatistics. About 40%-75% of papers had problems in reporting random allocation method, allocation concealment, random allocation implementation, blinding and similarity among groups, intention to treat and balancing benefits and harms. Moreover, at least 10% of papers inappropriately/not reported the design, protocol violations, sample size justification, subgroup/adjusted analyses, presenting flow diagram, drop outs, recruitment time, baseline data, suitable effect size on outcome, ancillary analyses, limitations and generalizability. Considering the shortcomings found and due to the importance of the RCTs for fall injury prevention programmes, their reporting quality should be improved. PMID- 29457921 TI - Ribociclib for the treatment of hormone receptor-positive, human epidermal growth factor receptor 2-negative advanced breast cancer. AB - INTRODUCTION: The emergence of cyclin-dependent kinases 4 and 6 (CDK4/6) inhibitors marked a significant advancement in the treatment of advanced breast cancer. Ribociclib is an orally bioavailable, highly selective inhibitor of CDK4/6. In combination with various endocrine therapies, ribociclib has demonstrated clinical activity as a first-line therapy for patients with HR+, HER2- advanced breast cancer, without compromising the favorable toxicity profile associated with endocrine therapy. Thus, ribociclib is now considered a new standard of care for HR+, HER2- advanced breast cancer. Areas covered: This review provides a concise overview of the preclinical and clinical development of ribociclib, including evidence of its clinical activity and safety profile when combined with endocrine therapy in HR+, HER2- advanced breast cancer. Expert commentary: CDK4/6 inhibition represents a promising treatment option for patients with HR+ metastatic breast cancer. Ribociclib significantly improved progression-free survival in patients receiving first-line endocrine therapy for HR+, HER2- advanced breast cancer. Planned and ongoing trials investigating ribociclib in combination with other endocrine therapies and in various clinical settings will help to determine the optimal treatment sequence for different patient populations. PMID- 29457922 TI - Evaluation of risk factors for recurrent primary common bile duct stone in patients with cholecystectomy. AB - OBJECTIVES: Recurrence of primary common bile duct (CBD) stone commonly occurs after complete removal of CBD stones in patients with cholecystectomy. This study aimed to investigate potential risk factors for the recurrence of primary CBD stones after endoscopic treatment. MATERIALS AND METHODS: Between January 2005 and December 2015, the endoscopic retrograde cholangiopancreatography (ERCP) database of our medical center was retrospectively reviewed; information regarding eligible patients who had recurrent CBD stones with a history of previous cholecystectomy was collected. The characteristics of the patients, CBD stone, CBD and ERCP-related factors were analyzed. RESULTS: The recurrence rate of CBD stone was 18.5% (115/622) after endoscopic treatment in patients with cholecystectomy. In univariate analysis, the number of CBD stones (>=2), CBD stone diameter (>=10 mm), stone composition, stone consistency, CBD diameter (>=15 mm), bile duct dilatation pattern, sharp bile duct angulation (<145 degrees ), balloon dilatation, large balloon (>12 mm) dilatation, endoscopic mechanical lithotripsy, endoscopic sphincterotomy, and endoscopic papillary balloon dilatation alone method were significant between the non-recurrence and recurrence groups. However, in multivariate analysis (based on the binary logistic regression method), the number of CBD stones (>=2) (adjusted odds ratio [AOR] 3.232; 95% confidence interval [CI] 1.344-7.773; p = .009), cholesterol stone (AOR 2.824; 95% CI 1.175-6.786; p =.02) and sharp bile duct angulation (<145 degrees ) (AOR 2.462; 95% CI 1.062-5.711; p = .036) were independent risk factors of CBD stone recurrence after cholecystectomy. CONCLUSIONS: CBD stone number (>=2), cholesterol stone and sharp bile duct angulation (<145 degrees ) are associated with recurrent common bile duct stones after cholecystectomy. PMID- 29457923 TI - Flipping social determinants on its head: Medical student perspectives on the flipped classroom and simulated patients to teach social determinants of health. AB - BACKGROUND: Inequalities in healthcare are increasing. Engaging medical students to tackle this urgent challenge alongside clinical sciences can be demanding. This study examines medical student perceptions of a flipped approach to health inequalities co-designed by faculty and sixth-year students. INNOVATION: A flipped learning session was piloted for year 4 medical students combining an online lesson followed by a tutorial with a simulated patient. METHODS: A mixed methods approach collected questionnaire data using 4-point Likert scales and free text answers. A semi-structured group interview was conducted with six voluntary participants. RESULTS: Two hundred and eighty-nine students completed questionnaires. 85% (n = 246) completed the online lesson. Students agreed the session helped their understanding of key concepts (mean 3.2), was improved by having an actor (mean = 3.6), and was enjoyable (mean = 3.2). Thematic analysis of qualitative questionnaire and interview data revealed three themes: engagement; structure; and attitudes towards social determinants of health. The simulation increased clinical relevance and students gained understanding of the impact of health inequalities upon individuals. CONCLUSIONS: This paper indicates flipped learning can increase clinical relevance and engagement in population health and person-centered care. Further work could assess changes in practice and attitudes of future doctors in tackling such global health challenges. PMID- 29457924 TI - Factors influencing audiologists' perception of moral climate in the workplace. AB - OBJECTIVE: The purpose of this study was to assess audiologists' perceptions of ethics and moral climate in the workplace. DESIGN: The Ethics Environmental Questionnaire (EEQ) was sent out to all audiologists registered with the professional body Audiology Australia. Participants were also invited to undertake a semi-structured interview. STUDY SAMPLE: A total of 301 audiologists completed the questionnaire. Eight of these participants also agreed to complete the interview. RESULTS: The overall mean on the EEQ was approximately equivalent to that of a positive ethical environment, with the exception of those working in adult rehabilitation settings who scored significantly poorer. Scores were significantly associated with state and age. Qualitative analysis from the interviews found that sales pressure from employers was the dominant cause for concern amongst the group. CONCLUSIONS: For those working in adult rehabilitation, moral distress is most likely to occur as the result of conflicting goals between the organisation and the audiologist. There is a need to regulate the practice at an organisational as well as individual level to ensure the focus remains on ethical practice. PMID- 29457925 TI - Controlled release of mitomycin C from PHEMAH-Cu(II) cryogel membranes. AB - Molecular imprinting technique was used for the preparation of antibiotic and anti-neoplastic chemotherapy drug (mitomycin C) imprinted cryogel membranes (MMC ICM). The membranes were synthezied by using metal ion coordination interactions with N-methacryloyl-(l)-histidine methyl ester (MAH) functional monomer and template molecules (i.e. MMC). The 2-hydroxyethyl methacrylate (HEMA) monomer and methylene bisacrylamide (MBAAm) crosslinker were used for the preparation of mitomycin C imprinted cryogel membranes by radical suspension polymerization technique. The imprinted cryogel membranes were characterized by scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET), Fourier transform infrared spectroscopy-attenuated total reflectance (FTIR-ATR) and swelling degree measurements. Cytotoxicity of MMC-ICMs was investigated using mouse fibroblast cell line L929. Time-dependent release of MMC was demonstrated within 150 h from cryogel membranes. Cryogels demonstrated very high MMC loading efficiency (70 80%) and sustained MMC release over hours. PMID- 29457926 TI - The contribution of theory to the design, delivery, and evaluation of interprofessional curricula: BEME Guide No. 49. AB - BACKGROUND: Interprofessional curricula have often lacked explicit reference to theory despite calls for a more theoretically informed field that illuminates curricular assumptions and justifies curricular practices. AIM: To review the contributions of theory to the design, delivery, and evaluation of interprofessional curricula. METHODS: Four databases were searched (1988-2015). Studies demonstrating explicit and a high-quality contribution of theory to the design, delivery or evaluation of interprofessional curricula were included. Data were extracted against a comprehensive framework of curricular activities and a narrative synthesis undertaken. RESULTS: Ninety-one studies met the inclusion criteria. The majority of studies (86%) originated from the UK, USA, and Canada. Theories most commonly underpinned "learning activities" (47%) and "evaluation" (54%). Theories of reflective learning, identity formation, and contact hypothesis dominated the field though there are many examples of innovative theoretical contributions. CONCLUSIONS: Theories contribute considerably to the interprofessional field, though many curricular elements remain under-theorized. The literature offers no "gold standard" theory for interprofessional curricula; rather theoretical selection is contingent upon the curricular component to which theory is to be applied. Theories contributed to interprofessional curricula by explaining, predicting, organizing or illuminating social processes embedded in interprofessional curricular assumptions. This review provides guidance how theory might be robustly and appropriately deployed in the design, delivery, and evaluation of interprofessional curricula.

PMID- 29457928 TI - An atraumatic retractor for interdisciplinary use in conventional laparoscopy and robotic surgery. AB - BACKGROUND: The removal of obstacles from the surgical field is a crucial aspect of any procedure in gynecological, urological or visceral laparoscopic surgery. Reliable instruments and skilled assistance are essential for the smooth execution of procedures. Blunt forceps are commonly used to keep tissue away from the operating field. The range of existing instruments has been enhanced by the introduction of laparoscopic retractors. However, no laparoscopic retractor can be used without causing tissue damage. MATERIAL AND METHODS: We describe the ALKATOUT retractor, an innovative laparoscopic retractor designed for atraumatic assistance in any laparoscopic procedure including robotic surgery. The advantages of this laparoscopic instrument were evaluated in a single-center study. RESULTS: The retractor has been used successfully in a variety of gynecological procedures and tested in laparoscopic procedures on human body donors. CONCLUSIONS: The results of a single-center questionnaire completed by 25 operating room staff (surgical nurses, residents, and specialists) confirm the advantages of the ALKATOUT retractor. PMID- 29457929 TI - Growth of the James Cook University Medical Program: Maintaining quality, continuing the vision, developing postgraduate pathways. AB - BACKGROUND: James Cook University (JCU) enrolled its first cohort of 64 in 2000 into a 6-year undergraduate medical program aimed at producing graduates capable of meeting the needs of North Queensland, Australia, with a focus on rural, remote, Indigenous and tropical health. The school's 1465 graduates over 13 cohorts who have a pattern of practice likely to meet the region's health needs. The JCU course was the first new Australian medical program for 25 years. The number of Australian medical schools has since doubled, while enrollments have almost tripled. METHODS: JCU's course features innovations such as dispersed, community-based education, rurally-focused selection, extended rural placements, and an emphasis on community needs - which are all now mainstream. This paper traces developments at JCU over the past decade, illustrating parallels with the broader Australian scene. RESULTS: Maintaining quality and educational integrity while numbers grow is challenging. The course has undergone modest curriculum redesign, but the fundamental elements are intact. The focus on meeting the region's needs remains, with some evolution of its mission to include social accountability and the needs of underserved populations. CONCLUSIONS: Postgraduate pathways are an important priority. Regional training hubs are being developed to support local pipelines into specialty practice. Queensland's Rural Generalist Pathway provides an incentivised pathway to rural practice while Generalist Medical Training provides a local training pipeline into general practice and rural medicine. As these initiatives mature, communities should benefit as JCU and other Australian programs continue to address local workforce needs. PMID- 29457930 TI - Nano-loaded human umbilical cord mesenchymal stem cells as targeted carriers of doxorubicin for breast cancer therapy. AB - The main challenge of anticancer drugs is poor tumor targeting. Now cellular carriers are widely investigated to deliver anticancer agents. As an ideal cellular candidate, human umbilical cord derived mesenchymal stem cells (hUC MSCs) possess inherent tropism potential to tumor. Here, we constructed hUC-MSCs carrying transferrin-inspired-nanoparticles that contain doxorubicin(hUC-MSCs-Tf inspired-NPs) to achieve enhanced anti-tumor efficacy and made an evaluation. Results represented that hUC-MSCs-Tf-inspired-NPs not only exhibit the controlled release property of Tf-inspired-NPs, but also integrate tumor tropism and penetrative abilities of MSCs. The tumor volume of nude mice bearing breast cancer MCF-7 treated with hUC-MSCs-Tf-inspired-NPs, was remarkably reduced compared to those treated with free drug or Tf-inspired-NPs. Thus, Tf-inspired NPs loaded hUC-MSCs have a potential to deliver anticancer drugs.

AB - The objective of this systematic review was to determine the effect on oral health-related outcomes from mandibular implant-retained dentures opposing maxillary complete dentures in edentulous middle-age and older adults, compared with complete removable dentures in both arches. Randomized controlled trials included participants with an average age of 65 years or older. The Cochrane Library, MEDLINE, and Web of Science were searched. A total of 228 abstracts were reviewed for inclusion criteria, with 14 trials included and analyzed for risk of bias. Eleven of these studies were assessed as being at an unclear risk of bias, and 3 were at high risk. Mandibular implant-retained overdenture therapy showed statistically significant improvements in the patients' general satisfaction ( P = .003), oral health-related quality of life ( P < .001), and chewing ability ( P < .001), over the patients with complete dentures. There were no significant differences in the percentage of patients who were satisfied with their overdentures vs complete dentures for comfort, retention, esthetics, or chewing ability; however, only 2 studies reported these outcomes. In terms of nutritional status 1 year after treatment, vitamin B12 blood levels increased significantly in the implant-retained group ( P = .003), but not the other nutritional values. Implant-retained mandibular overdentures are an option for middle-aged and elderly edentulous patients as they significantly improve some of the outcomes; however, the quality of the evidence was moderate/low, due to the small number of studies included and the risk of bias. Future research should include objective outcomes such as masticatory performance, chewing efficacy, and muscular coordination. PMID- 29457933 TI - Computer-Guided Inferior Alveolar Nerve Lateralization With Simultaneous Implant Placement: A Preliminary Report. AB - Placement of dental implants in the posterior mandibular alveolar ridges may become a challenging procedure because of limited bone height between the crest of the ridge and the inferior alveolar canal. The aim of this study was to introduce an innovative, less invasive, highly accurate, and easy surgical technique of inferior alveolar nerve lateralization in the posterior deficient mandible using a special customized 3-dimensional-printed surgical guide to enhance the bone height for implant placement. This case series study included 7 patients with unilateral edentulous mandibular alveolar ridges. Customized surgical guides were manufactured using fused deposition modeling technology to accurately place a rectangular window to uncover the canal and also for immediate placement of dental implants in all cases. The results of this limited study provided information on an innovative technique that decreased intraoperative time and demonstrated decreased risks for (1) inferior alveolar nerve injury and (2) postoperative nerve dysfunction.

PMID- 29457934 TI - Early Placement of Dental Implants in Maxillary Sinus Grafted With Leukocyte and Platelet-Rich Fibrin and Deproteinized Bovine Bone Mineral. AB - This case report aimed to describe the effects of leukocyte and platelet-rich fibrin (L-PRF) associated with demineralized bovine bone mineral (DBBM) and absorbable collagen membrane (CM) on bone regeneration in maxillary sinus augmentation. A 59-year-old male patient was referred to the Department of Periodontology for implant rehabilitation of his edentulous upper jaw. The treatment plan involved maxillary sinus augmentation followed by implant installations. A split-mouth design was employed in which the right maxillary sinus was filled using L-PRF, DBBM, and CM; the left side was filled with DBBM and CM. After 4 and 8 months postoperatively, 2 dental implants were installed in each of the right and left maxillary sinuses. Cone-beam computerized tomography (CBCT) was taken before and after sinus augmentation for evaluation of tridimensional bone volume alterations. Bone biopsies were harvested from the implant sites for histomorphometric evaluation. Resonance frequency analysis was employed immediately after implant placement and before prosthetic rehabilitation for evaluation of implant stability. Implants were loaded 10 months after sinus augmentation. CBCT analysis showed a higher resorption rate in the right side of the maxillary sinus (L-PRF + DBBM) compared to the left side (22.25% and 8.95%, respectively). Implant stability quotients were above 68 in all time-points for both groups. Histomorphometric analysis showed a high amount of newly formed bone when L-PRF was used compared with DBBM alone (2 118 102 and 975 535 mm3, respectively). Taken together, both techniques were effective for maxillary sinus augmentation, however the addition of L-PRF to the graft allowed early implant placement and accelerated bone healing in the conditions studied. PMID- 29457936 TI - Prevalence, Structure, and Distribution of Novel Parasite Cysts Containing Dracunculus Species in River Otters ( Lontra canadensis) from Arkansas. AB - Adult female guinea worms ( Dracunculus spp.) usually are reported to occur singly in the extremities of their hosts, from which they deliver their larvae into the water through fistulae in the host's skin. We visually examined for the presence of worms in the fascia of the limbs of skinned carcasses of 184 river otters ( Lontra canadensis) harvested in Arkansas and report observations of cysts on wrists and ankles found on 12 otters. Cysts averaged 15.6 * 24.6 mm in diameter, were round to oval, and contained masses of up to 19 adult female Dracunculus sp. (mean 6.7). We speculate that high levels of infection in consumed paratenic hosts might have caused high infection rates, leading to large cyst formation in otters, as larvigerous Dracunculus sp. females accumulated in extremities. No males were discovered during the study, so identification of a sample of worms was based on molecular techniques. PMID- 29457937 TI - Support with nutrition for women receiving chemotherapy for breast cancer. AB - Nurses are in a unique position to provide nutritional advice and information to women with breast cancer who are undergoing chemotherapy, supporting them with making decisions regarding nutrition and diet. This narrative review evaluated the research evidence relating to the nutritional challenges experienced during chemotherapy and the most effective approaches for supporting women in dietary choice. Weight gain was identified as a specific problem for women undergoing chemotherapy. The evidence indicated that information about nutrition and food preparation support may go some way in assisting women to overcome some of the nutrition-related difficulties experienced during chemotherapy treatment for breast cancer. However, further research is required to better inform person centred nursing practice in this area. PMID- 29457938 TI - Predicting and preventing alcohol relapse in alcohol-related liver disease. AB - BACKGROUND: despite a 450% increase in UK alcohol-related liver disease mortality over the past 30 years, little evidence-based guidance exists regarding preventing recidivism post-liver transplant for alcohol-related liver disease. METHOD: a systematic literature review was conducted to identify demographic variables predictive of alcohol relapse and effective psychosocial interventions for alcohol-related liver disease patients post-liver transplant. RESULTS: variables most significantly predictive of alcohol relapse post-transplant were less than 12 months pre-liver transplant abstinence; patients with children; poor pre-liver transplant psychosomatic evaluation; non-compliance with post-liver transplant treatment plan; and patients with active insurance policies. Structured management was the most effective psychosocial intervention in preventing alcohol relapse. CONCLUSION: findings should be interpreted cautiously, due to limited and poor-quality evidence. Rigorously designed further research of the psychosocial interventions targeting predictive demographic variables is recommended. PMID- 29457940 TI - Needed: a retention strategy.

AB - AIM: to explore the nature of leadership styles used by the nursing management team, as perceived by nurses working at the bedside. BACKGROUND: leadership style is related to job satisfaction, staff retention, costs, and quality of care. The leadership styles of managers can be crucial in the healthcare setting, but very few studies have focused on them. METHOD: the study employed qualitative methodology, involving 35 nurses working in different specialties of a medical city in Saudi Arabia. Data collection consisted of completing demographic and professional information and a semi-structured interview using open-ended questions. ANALYSIS: a phenomenologic-hermeneutic approach was used to identify major themes. RESULTS: the findings showed that participants described four types of leadership styles: relational leadership, preferential leadership, communication chain leadership, and ineffectual leadership. CONCLUSION: the leadership style employed by nurse managers has a major impact on nurses' satisfaction, turnover, and the quality of patient care they deliver.

AB - BACKGROUND: nurses play a crucial role in the early recognition and management of the deteriorating patient. They are responsible for the care they provide to their patients, part of which is the monitoring of vital signs (blood pressure, pulse, respiratory rate and temperature), which are fundamental in the surveillance of deterioration. The aim of this study was to discover what factors influence how nurses assess patient acuity and their response to acute deterioration. METHODS: a generic qualitative approach was used. Some 10 nurses working in an acute NHS trust were interviewed using a semi- structured approach, with equal representation from medical and surgical inpatient wards. RESULTS: the main themes identified were collegial relationships, intuition, and interpretation of the MEWS system (Modified Early Warning Score). Collegial relationships with the medical staff had some influence on the nurses' assessment, as they tended to accept the medical peers' assessment as absolute, rather than their own assessment. It was also highlighted that nurses relied on the numerical escalation of the MEWS system to identify the deteriorating patient, instead of their own clinical judgement of the situation. Interestingly, the nurses found no difficulty in escalating the patient's care to medical staff when the patient presented with a high MEWS score. The difficulty arose when the MEWS score was low-the participants found it challenging to authenticate their findings. CONCLUSION: this study has identified several confounding factors that influence the ways in which nurses assess patient acuity and their response to acute deterioration. The information provides a crucial step forward in identifying strategies to develop further training. PMID- 29457946 TI - The provision of ambulatory systemic anti-cancer therapy.

PMID- 29457950 TI - Knowledge and skills of critical care nurses in assisting with intubation. AB - Assisting with tracheal intubation is an aspect of clinical practice that requires knowledge and skill if the procedure is to be carried out in a timely and safe manner. Maintaining this knowledge and skill requires good quality education and regular opportunities to practise. These two factors appear to be inconsistent in critical care units. This article details an audit performed on a large tertiary referral centre critical care unit. It was undertaken in two phases: the first was a self-assessment of knowledge and the second was a practical assessment of the audit subjects in a simulated setting. Results indicated that formal training was inconsistent, as was the opportunity to assist with tracheal intubation. These factors may have contributed to the varying levels of skill seen in the practical assessment phase. The authors recommend devising a standardised training programme to address these issues, which could be distributed nationally. High standards need to be instilled early in critical care nurses' careers, with regular updates to maintain knowledge and skills.

AB - This article presents a snapshot of my experience of being a nurse who became a service user with breast cancer. It begins by outlining the Humanization of Healthcare Framework ( Todres et al, 2009 ), which is a values-based context that can be used to underpin daily care. Generic applications for each of the dimensions of the framework are suggested. This framework is then used to contextualise my experience of receiving my diagnosis and the ensuing chemotherapy. Using examples from my personal narrative, I make some recommendations for 'small actions' that can contribute to more humanised and person-centred care. I also hope that this narrative prompts reflection by the reader and so improves the quality of care given to others. PMID- 29457955 TI - A quality project for radiation reduction in the cath lab. AB - The radiation exposure in the cath lab of patients, cardiologists, and nurses was measured during three consecutive periods of 8 weeks. The first 8 weeks the baseline radiation exposure was obtained. In the second period standard incidences for coronarography and frame rate were changed, without compromising the image quality of the examination. In the third period, a pelvic shield covered the lower part of the patient. This pilot quality project demonstrates that further significant reduction in radiation exposure of 37% is possible for patients. A significant reduction in radiation exposure of 53 and 62% was obtained among cardiologists and nurses working in the cath lab, even with the already diminished radiation exposure over the last years by better equipment and general radioprotection measures.

AB - Mosquito control using chemical insecticides is facing a major challenge due to development of insecticide resistance. Improving the efficiency of existing insecticides using synergistic secondary metabolites of biological origin is increasingly being researched. Herein, we evaluated the toxicity of Fusarium oxysporum extract alone and in binary combinations with temephos, on larvae and pupae of Anopheles stephensi, Aedes aegypti and Culex quinquefaciatus. F. oxysporum extract was characterized using TLC, FT-IR and GC-MS. After 24 h of exposure, the binary combination of temephos + F. oxysporum extract (1:1 ratio) was highly toxic to larvae of An. stephensi (LC50: 35.927 MUg/ml), Ae. aegypti (LC50: 20.763 MUg/ml) and Cx. quinquefasciatus, (LC50: 51.199 MUg/ml). For pupae LC50 values were 38.668, 26.394, and 72.086 MUg/ml, respectively. Histology studies of mosquitoes exposed to F. oxysporum extract showed vacuolation in epithelium, as well as in adipose, and muscle tissues of larval midgut. Overall, our results show that the synergistic combination of temephos and F. oxysporum extract is highly effective to control mosquito young instars. PMID- 29457956 TI - Gene drives to fight malaria: current state and future directions. AB - Self-propagating gene drive technologies have a number of desirable characteristics that warrant their development for the control of insect pest and vector populations, such as the malaria-transmitting mosquitoes. Theoretically easy to deploy and self-sustaining, these tools may be used to generate cost effective interventions that benefit society without obvious bias related to wealth, age or education. Their species-specific design offers the potential to reduce environmental risks and aim to be compatible and complementary with other control strategies, potentially expediting the elimination and eradication of malaria. A number of strategies have been proposed for gene-drive based control of the malaria mosquito and recent demonstrations have shown proof-of-principle in the laboratory. Though several technical, ethical and regulatory challenges remain, none appear insurmountable if research continues in a step-wise and open manner. PMID- 29457959 TI - Biosynthesis and applications of prenylquinones. AB - Prenylquinones are isoprenoid compounds with a characteristic quinone structure and isoprenyl tail that are ubiquitous in almost all living organisms. There are four major prenylquinone classes: ubiquinone (UQ), menaquinone (MK), plastoquinone (PQ), and rhodoquinone (RQ). The quinone structure and isoprenyl tail length differ among organisms. UQ, PQ, and RQ contain benzoquinone, while MK contains naphthoquinone. UQ, MK, and RQ are involved in oxidative phosphorylation, while PQ functions in photosynthetic electron transfer. Some organisms possess two types of prenylquinones; Escherichia coli has UQ8 and MK8, and Caenorhabditis elegans has UQ9 and RQ9. Crystal structures of most of the enzymes involved in MK synthesis have been solved. Studies on the biosynthesis and functions of quinones have advanced recently, including for phylloquinone (PhQ), which has a phytyl moiety instead of an isoprenyl tail. Herein, the synthesis and applications of prenylquinones are reviewed. PMID- 29457960 TI - Phylogenetic Relationships and Acaricidal Effects of Beauveria bassiana Obtained from Cattle Farm Soils Against Rhipicephalus microplus. AB - The objectives of the present study were to isolate Beauveria bassiana strains from cattle farm soils, analyze the phylogenetic relationships among the fungal strains isolated from these soils, and determine the acaricidal effect of B. bassiana isolates on engorged Rhipicephalus microplus tick strains resistant or susceptible to chemical acaricides. Six strains of B. bassiana were obtained and isolated from cattle farm soils in the Mexican tropics using the Galleria bait method, and their acaricidal effect was assessed against 2 populations of R. microplus ("Media Joya" chemical acaricide-resistant strain or "CLAR" chemical acaricide-susceptible strain) using the adult immersion test. The BbV03 strain produced 86.7% and 60% mortality in resistant and susceptible ticks on day 20, respectively, whereas the BbV04 strain produced 66.7% and 53.5% mortality in resistant and susceptible ticks on day 20, respectively. The BbV03 and BbV04 strains reduced egg laying on both R. microplus populations. There was no statistical difference in the acaricidal effect of B. bassiana strains among chemical acaricide-susceptible or -resistant R. microplus populations ( P > 0.05). The BbV03 strain was the most virulent against R. microplus with an LC50 of 2 * 107 and LC99 of 7 * 108 conidia/ml. We found that the 6 B. bassiana isolated clustered in the same clade with other previously reported B. bassiana strains (from GenBank) but were separated into 3 different sub-clades. This study shows that some B. bassiana strains are a promising coadjuvant alternative for biological tick control, including tick populations that are resistant to chemical acaricides. Beauveria bassiana is present in the pastures of tropic cattle farms, and there are genetic variations between B. bassiana strains living in this ecosystem that might play an important role in the natural control of R. microplus in cattle farm paddocks.

PMID- 29457962 TI - Genotype Identification and Phylogenetic Analysis of Enterocytozoon bieneusi Isolates from Stool Samples of Diarrheic Children. AB - Among approximately 14 human-pathogenic microsporidian species, Enterocytozoon bieneusi is the most common. It can inhabit the small intestines, causing chronic diarrhea and wasting syndrome. Prevalence and genotype data for E. bieneusi in humans is available for only a few provinces of China. In the current study, 93 fecal specimens were collected from diarrheic children in Chongqing. Polymerase chain reaction amplification and sequencing of the internal transcribed spacer ( ITS) region of the E. bieneusi rDNA sequence identified 11 (11.83%) positive specimens. Among them, 8 (8.60%) are from patients of ages ranging from 2 mo to 6 yr old and 3 (3.23%) from patients 7 to 11 yr old. In total, 6 genotypes (4 novel genotypes and 2 known genotypes) were identified in this study. Phylogenetic analysis showed that all the genotypes identified in the present study belong to group 1, which previously has been described as a zoonotic group. This could mean these infections were acquired zoonotically, and it may be prudent to warn those people having close contact with animals of this potential risk. PMID- 29457963 TI - 3-T MR Imaging of Proximal Femur Microarchitecture in Subjects with and without Fragility Fracture and Nonosteoporotic Proximal Femur Bone Mineral Density. AB - Purpose To determine if 3-T magnetic resonance (MR) imaging of proximal femur microarchitecture can allow discrimination of subjects with and without fragility fracture who do not have osteoporotic proximal femur bone mineral density (BMD). Materials and Methods Sixty postmenopausal women (30 with and 30 without fragility fracture) who had BMD T scores of greater than -2.5 in the hip were recruited. All subjects underwent dual-energy x-ray absorptiometry to assess BMD and 3-T MR imaging of the same hip to assess bone microarchitecture. World Health Organization Fracture Risk Assessment Tool (FRAX) scores were also computed. We used the Mann-Whitney test, receiver operating characteristics analyses, and Spearman correlation estimates to assess differences between groups, discriminatory ability with parameters, and correlations among BMD, microarchitecture, and FRAX scores. Results Patients with versus without fracture showed a lower trabecular plate-to-rod ratio (median, 2.41 vs 4.53, respectively), lower trabecular plate width (0.556 mm vs 0.630 mm, respectively), and lower trabecular thickness (0.114 mm vs 0.126 mm) within the femoral neck, and higher trabecular rod disruption (43.5 vs 19.0, respectively), higher trabecular separation (0.378 mm vs 0.323 mm, respectively), and lower trabecular number (0.158 vs 0.192, respectively), lower trabecular connectivity (0.015 vs 0.027, respectively) and lower trabecular plate-to-rod ratio (6.38 vs 8.09, respectively) in the greater trochanter (P < .05 for all). Trabecular plate-to rod ratio, plate width, and thickness within the femoral neck (areas under the curve [AUCs], 0.654-0.683) and trabecular rod disruption, number, connectivity, plate-to-rod ratio, and separation within the greater trochanter (AUCs, 0.662 0.694) allowed discrimination of patients with fracture from control subjects. Femoral neck, total hip, and spine BMD did not differ between and did not allow discrimination between groups. FRAX scores including and not including BMD allowed discrimination between groups (AUCs, 0.681-0.773). Two-factor models (one MR imaging microarchitectural parameter plus a FRAX score without BMD) allowed discrimination between groups (AUCs, 0.702-0.806). There were no linear correlations between BMD and microarchitectural parameters (Spearman rho, -0.198 to 0.196). Conclusion 3-T MR imaging of proximal femur microarchitecture allows discrimination between subjects with and without fragility fracture who have BMD T scores of greater than -2.5 and may provide different information about bone quality than that provided by dual-energy x-ray absorptiometry.

AB - Purpose To determine the outcomes after initial therapy in patients with chronic liver disease and retrospectively assigned Liver Imaging Reporting and Data System (LI-RADS; version 2014) category 4 (LR-4) and 5 (LR-5) nodules at gadoxetate disodium-enhanced MR imaging. Materials and Methods In this retrospective study, 260 patients with a single LR-4 (n = 132) or LR-5 (n = 128) nodule who were assigned a LI-RADS category were included. Patients were identified between January 2012 and December 2012, and were initially treated by resection, liver transplant, radiofrequency ablation (RFA), or transcatheter arterial chemoembolization (TACE) according to the Barcelona Clinic Liver Cancer staging system. Follow-up continued until August 31, 2016. The incidences of local tumor recurrence (ILRs) and distant tumor recurrence (IDRs) and recurrence free survival (RFS) were compared between the LR-4 and LR-5 patients. For each category, ILRs, IDRs, and RFS were compared across the four treatments. Results LR-5 patients were more frequently treated by surgical resection than LR-4 patients (72.7% [93 of 128] vs 41.7% [55 of 132], respectively; P < .001), but less frequently treated by RFA (19.5% [25 of 128] vs 30.3% [40 of 132], respectively; P = .047) and TACE (6.3% [eight of 128] vs 22.0% [29 of 132], respectively; P < .001). ILRs and IDRs were not significantly different between LR-4 and LR-5 patients according to the type of treatment (0%-48.3% [14 of 29] vs 0%-25.0% [two of eight], P $ .423; 0%-55.2% [16 of 29] vs 0%-37.5% [three of eight], P $ .447, respectively). There was no difference in RFS between the two categories (36.3 months vs 41.7 months, respectively; P = .084). Liver transplant showed no local or distant tumor recurrence in either category. Resection showed higher RFS and lower ILR and IDR than RFA and TACE in both LR-4 and LR-5 patients. Conclusion Patients with LR-4 nodules had ILRs and IDRs similar to patients with LR-5 nodules when stratified by treatment type. RFS was also similar between patients with LR-4 and LR-5 nodules. Among the four initial treatments, liver transplant and resection showed better local tumor control, with longer RFS than RFA or TACE.

AB - ReS2, a layered two-dimensional material popular for its in-plane anisotropic properties, is emerging as one of the potential candidates for flexible electronics and ultrafast optical applications. It is an n-type semiconducting material having a layer independent bandgap of 1.55 eV. In this paper we have characterized the intrinsic electronic noise level of few-layer ReS2 for the first time. Few-layer ReS2 field effect transistor devices show a 1/f nature of noise for frequency ranging over three orders of magnitude. We have also observed that not only the electrical response of the material is anisotropic; the noise level is also dependent on direction. In fact the noise is found to be more sensitive towards the anisotropy. This fact has been explained by evoking the theory where the Hooge parameter is not a constant quantity, but has a distinct power law dependence on mobility along the two-axes direction. The anisotropy in 1/f noise measurement will pave the way to quantify the anisotropic nature of two dimensional (2D) materials, which will be helpful for the design of low-noise transistors in future.

AB - BACKGROUND Histone acetylation and DNA methylation are important mammalian epigenetic modifications that participate in the regulation of gene expression. Because dysregulation of histone deacetylase and DNA methyltransferases are hallmarks of malignancy, they have become promising therapeutic targets. In this study, we explored the anti-tumor activity of valproic acid (VPA), a histone deacetylase inhibitor (HDACi) and 5-Aza-2'-deoxycytidine (5-Aza), an inhibitor of DNA methyltransferases, on renal cell carcinoma (RCC) cell lines 786-O and 769-P. MATERIAL AND METHODS The cell proliferation was detected by xCELLigence RTCA DP Instrument, viability by CCK8 assay, cell apoptosis and cell cycle by flow cytometry, and cell migration by wound healing assay, Transwell assay and xCELLigence RTCA DP Instrument. RESULTS We discovered that VPA and 5-Aza could individually induce decreased viability and have an inhibitory effect on the proliferation of 786-O and 769-P cells. This anti-growth effect was more pronounced when the cells were treated with both VPA and 5-Aza. The combination of VPA and 5-Aza also elicited more apoptosis and produced more cell cycle arrest in the G1 phase for both cell lines. On the other hand, treatment of RCC cells with VPA, 5-Aza, or a combination of both resulted in slow wound healing and impaired migration. CONCLUSIONS These findings clearly demonstrated that VPA combined with 5-Aza could significantly increase anti-RCC effects by inhibiting cellular proliferation, inducing apoptosis, promoting cell cycle arrest and prohibiting the migration of human RCC cells. PMID- 29457967 TI - DNA damage and genomic instability among workers formerly and currently exposed to asbestos. AB - Objectives Despite an asbestos ban in the European Union, exposure to asbestos still represents an occupational risk. Biomarkers of DNA damage and genomic instability in groups exposed to asbestos may contribute to the identification of subgroups/subjects at higher risk. Methods A cross-sectional study was conducted on 468 male individuals (80 working in occupational settings with potential exposure to asbestos fibers, 202 retired workers with past exposure, and 186 non exposed controls) to compare genomic instability, cell proliferation and differentiation level using the non-invasive micronucleus buccal cytome assay. Data on demographic variables, lifestyle, and occupational history were collected with a standardized questionnaire. Micronuclei (MN) and other biomarkers of DNA damage and genomic instability were scored in a minimum of 2000/1000 cells per individual, respectively. Results Univariate and multivariate analysis showed opposite associations of MN frequency with current and former exposure. Compared to unexposed controls, workers with current potential exposure to asbestos had 55% lower MN frequency [95% confidence interval (CI) 71-29%, P<0.001] while those with past exposure had 34% higher MN frequency (95% CI 1-77%, P<0.001). The frequency of cells with condensed chromatin and binucleated cells was elevated among formerly exposed workers. The multivariate analysis did not reveal any actual confounders, although lower MN frequency was observed among subjects eating fresh fruit or vegetables every day or taking vitamin supplements. Conclusions Active workers with potential exposure to asbestos fibers did not show increased genomic damage. On the contrary, workers exposed in the past experienced a persistently elevated genomic instability, which may be used for risk assessment at subgroup or individual level. PMID- 29457969 TI - An evaluation of the operational model when applied to quantify functional selectivity. AB - BACKGROUND AND PURPOSE: Functional selectivity describes the ability of ligands to differentially regulate multiple signalling pathways when coupled to a single receptor, and the operational model is commonly used to analyse these data. Here, we assess the mathematical properties of the operational model and evaluate the outcomes of fixing parameters on model performance. EXPERIMENTAL APPROACH: The operational model was evaluated using both a mathematical identifiability analysis and simulation. KEY RESULTS: Mathematical analysis revealed that the parameters R0 and KE were not independently identifiable which can be solved by considering their ratio, tau. The ratio parameter, tau, was often imprecisely estimated when only functional assay data were available and generally only the transduction coefficient R ( tauKA) could be estimated precisely. The general operational model (that includes baseline and the Hill coefficient) required either the parameters Em or KA to be fixed. The normalization process largely cancelled out the mean error of the calculated Deltalog (R) caused by fixing these parameters. From this analysis, it was determined that we can avoid the need for a full agonist ligand to be included in an experiment to determine Deltalog (R). CONCLUSION AND IMPLICATIONS: This analysis has provided a ready-to use understanding of current methods for quantifying functional selectivity. It showed that current methods are generally tolerant to fixing parameters. A new method was proposed that removes the need for including a high efficacy ligand in any given experiment, which allows application to large-scale screening to identify compounds with desirable features of functional selectivity. PMID- 29457970 TI - Synthesis of Palladium Nanoscale Octahedra through a One-Pot, Dual-Reductant Route and Kinetic Analysis. AB - Shape-controlled synthesis of colloidal metal nanocrystals has traditionally relied on the use of an approach that involves the reduction of a metal precursor by a single reductant. Once the concentration of atoms surpasses supersaturation, they will undergo homogeneous nucleation to generate nuclei and then seeds, followed by further growth into nanocrystals. In general, it is a grand challenge to optimize such an approach because the kinetic requirement for nucleation tends to be drastically different from what is needed to guide the growth process. In this work, we overcome this difficulty by switching to a dual-reductant approach, in which both strong and weak reductants are added into the same reaction solution. By controlling their amounts to program the reduction kinetics, the strong reductant only regulates the homogeneous nucleation process to generate the desired seeds, and once consumed, the weak reductant takes over to control the growth pattern and thereby the shape of the resulting nanocrystals. PMID- 29457968 TI - In vitro and in vivo effects of MK2206 and chloroquine combination therapy on endometriosis: autophagy may be required for regrowth of endometriosis. AB - BACKGROUND AND PURPOSE: A high recurrence rate after medical treatment is a major clinical problem for patients with endometriosis. Here, we have evaluated the in vitro effects of combined treatment with MK2206 (an AKT inhibitor) + chloroquine on cell growth and regrowth of endometriotic stromal cells and the in vivo effects on endometriotic implants in a mouse xenograft model of endometriosis. EXPERIMENTAL APPROACH: We evaluated the effects of autophagy inhibition by knockdown of the ATG13, Beclin-1 and ATG12 genes and pharmacological agents (chloroquine, bafilomycin A1 or 3-methyalanine) individually and in combination with MK2206 on cell growth and/or cell regrowth of endometriotic stromal cells in vitro. Furthermore, we evaluated treatment with MK2206 + chloroquine on endometriotic implants in a mouse xenograft model of endometriosis. KEY RESULTS: Combined treatment with MK2206 and chloroquine markedly reduced cell growth and regrowth after discontinuation of treatment in endometriotic stromal cells compared with cells treated with either drug alone. Autophagy inhibition by ATG13, Beclin-1 or ATG12 gene knockdown only affected regrowth of endometriotic stromal cells, but not endometrial stromal cells from the same patients, after a 72 h discontinuation of the combined treatment. Furthermore, combined treatment reduced the size of endometriotic implants, whereas no effects on endometriotic implants treated with either drug alone were observed in a mouse xenograft model of endometriosis. CONCLUSIONS AND IMPLICATIONS: The present findings suggest that a novel strategy for treatment of endometriosis may involve decreasing the number of endometriotic cells that can survive treatment and then preventing regrowth by autophagy inhibition. PMID- 29457971 TI - Visible-Light Photocatalysis: Does It Make a Difference in Organic Synthesis? AB - Visible-light photocatalysis has evolved over the last decade into a widely used method in organic synthesis. Photocatalytic variants have been reported for many important transformations, such as cross-coupling reactions, alpha-amino functionalizations, cycloadditions, ATRA reactions, or fluorinations. To help chemists select photocatalytic methods for their synthesis, we compare in this Review classical and photocatalytic procedures for selected classes of reactions and highlight their advantages and limitations. In many cases, the photocatalytic reactions proceed under milder reaction conditions, typically at room temperature, and stoichiometric reagents are replaced by simple oxidants or reductants, such as air, oxygen, or amines. Does visible-light photocatalysis make a difference in organic synthesis? The prospect of shuttling electrons back and forth to substrates and intermediates or to selectively transfer energy through a visible-light-absorbing photocatalyst holds the promise to improve current procedures in radical chemistry and to open up new avenues by accessing reactive species hitherto unknown, especially by merging photocatalysis with organo- or metal catalysis.

AB - A majority of metal-organic frameworks (MOFs) fail to preserve their physical and chemical properties after exposure to acidic, neutral, or alkaline aqueous solutions, therefore limiting their practical applications in many areas. The strategy demonstrated herein is the design and synthesis of an organic ligand that behaves as a buffer to drastically boost the aqueous stability of a porous MOF (JUC-1000), which maintains its structural integrity at low and high pH values. The local buffer environment resulting from the weak acid-base pairs of the custom-designed organic ligand also greatly facilitates the performance of JUC-1000 in the chemical fixation of carbon dioxide under ambient conditions, outperforming a series of benchmark catalysts.

AB - High-nitrogen-content compounds have attracted great scientific interest and technological importance because of their unique energy content, and they find diverse applications in many fields of science and technology. Understanding of structure-property relationship trends and how to modify them is of paramount importance for their further improvement. Herein, the installation of oxygen-rich modules, C(NO2 )3 , C(NO2 )2 F, or C(NO2 )2 NF2 , into an endothermic framework, that is, the combination of a nitropyrazole unit and tetrazole ring, is used as a way to design novel energetic compounds. Density, oxygen balance, and enthalpy of formation are enhanced by the presence of these oxygen-containing units. The structures of all compounds were confirmed by XRD. For crystal packing analysis, it is proposed to use new criterion, DeltaOED , that can serve as a measure of the tightness of molecular packing upon crystal formation. Overall, the materials show promising detonation and propulsion parameters.

AB - Phytohormones are central to plant growth and development. Despite the advancement in our knowledge of hormone signaling, downstream targets, and their interactions upon hormones action remain largely fragmented, especially at the protein and metabolite levels. With an aim to get new insight into the effects of two hormones, ethylene (ET) and abscisic acid (ABA), this study utilizes an integrated proteomics and metabolomics approach to investigate their individual and combined (ABA+ET) signaling in soybean leaves. Targeting low-abundance proteins, our previously established protamine sulfate precipitation method was applied, followed by label-free quantification of identified proteins. A total of 4129 unique protein groups including 1083 differentially modulated in one (individual) or other (combined) treatments were discerned. Functional annotation of the identified proteins showed an increased abundance of proteins related to the flavonoid and isoflavonoid biosynthesis and MAPK signaling pathway in response to ET treatment. HPLC analysis showed an accumulation of isoflavones (genistin, daidzein, and genistein) upon ET treatment, in agreement with the proteomics results. A metabolome analysis assigned 79 metabolites and further confirmed the accumulation of flavonoids and isoflavonoids in response to ET. A potential cross-talk between ET and MAPK signaling, leading to the accumulation of flavonoids and isoflavonoids in soybean leaves is suggested. PMID- 29457975 TI - Fluorescent DNA Probing Nanoscale MnO2: Adsorption, Dissolution by Thiol, and Nanozyme Activity. AB - Manganese dioxide (MnO2) is an interesting material due to its excellent biocompatibility and magnetic properties. Adsorption of DNA to MnO2 is potentially of interest for drug delivery and sensing applications. However, little fundamental understanding is known about their interactions. In this work, carboxyfluorescein (FAM)-labeled DNA oligonucleotides were used to explore the effect of salt concentration, pH, and DNA sequence and length for adsorption by MnO2, and comparisons were made with graphene oxide (GO). The DNA desorbs from MnO2 by free inorganic phosphate, while it desorbs from GO by adenosine and urea. Therefore, DNA is mainly adsorbed on MnO2 through its phosphate backbone, and DNA has a stronger affinity on MnO2 than on GO based on a salt-shock assay. At the same time, DNA was used to study the effect of thiol containing compounds on the dissolution of MnO2. Adsorbed DNA was released from MnO2 after its dissolution by thiol, but not from other metal oxides with lower solubility such as CeO2, TiO2, and Fe3O4. DNA-functionalized MnO2 was then used for detecting glutathione (GSH) with a detection limit of 383 nM. Finally, DNA was found to inhibit the peroxidase-like activity of MnO2. This study has offered many fundamental insights into the interaction between MnO2 and two important biomolecules: DNA and thiol-containing compounds.

Despite the potential of an MT imaging agents, no PET ligand is currently available for in vivo imaging of MTs in the brain. We radiolabeled [11C]MPC-6827, a high affinity MTA, and demonstrated its specific binding in rat and mice brain using PET imaging. Our experiments show that [11C]MPC-6827 has specific binding to MT in brain, and it is the first MT-binding PET ligand. PMID- 29457978 TI - Size-Dependent Thermodynamics and Kinetics of Adsorption on Nanoparticles: A Theoretical and Experimental Study. AB - Owing to their excellent adsorption properties compared with those of the corresponding bulk materials, nanoparticles have been widely applied in many fields. Their properties depend on the thermodynamics and kinetics of adsorption, which depend on the particle size. In this paper, we present universal theories of the thermodynamics and kinetics for nanoadsorption that have been developed over the past few years. Theoretically, we have derived relationships between the adsorption thermodynamic properties and the particle size, as well as those between the adsorption kinetic parameters and the particle size. Moreover, we discuss the regularities and mechanisms of influence of the particle size on the thermodynamics and kinetics of adsorption. Experimentally, taking the adsorption of methyl orange on nano-CeO2 in aqueous solution as a system, we have studied the size-dependent thermodynamics and kinetics of the system, and the size dependences were confirmed to be consistent with the theoretical relationships. The results indicate that particle size has a significant effect on the thermodynamic properties and kinetic parameters of adsorption: with decreasing particle size of nano-CeO2, the adsorption equilibrium constant K? and the adsorption rate constant k increase, while the molar Gibbs free energy of adsorption Deltaads Gm?, the molar adsorption entropy Deltaads Sm?, the molar adsorption enthalpy Deltaads Hm?, the adsorption activation energy Ea, and the adsorption pre-exponential factor A all decrease. Indeed, ln K?, Deltaads Gm?, Deltaads Sm?, Deltaads Hm?, ln k, Ea, and ln A are each linearly related to the reciprocal of particle size. Furthermore, thermodynamically, Deltaads Gm? and ln K? are influenced by the molar surface area and the difference in surface tensions, Deltaads Sm? is influenced by the molar surface area and the difference in temperature coefficients of surface tension, and Deltaads Hm? is influenced by the molar surface area, the difference in surface tensions, and the difference in temperature coefficients of surface tension. Kinetically, Ea is influenced by the partial molar surface enthalpy of the nanoadsorbent, ln A is influenced by the partial molar surface entropy, and ln k is influenced by the partial molar surface Gibbs energy. The theories can quantitatively describe adsorption behavior on nanoparticles, explain the regularities and mechanisms of influence of particle size, and provide guidance for the research and application of nanoadsorption.

AB - Here, we demonstrate that the use of the single-molecule centroid localization algorithm can improve the accuracy of fluorescence binding assays. Two major artifacts in this type of assay, i.e., nonspecific binding events and optically overlapping receptors, can be detected and corrected during analysis. The effectiveness of our method was confirmed by measuring two weak biomolecular interactions, the interaction between the B1 domain of streptococcal protein G and immunoglobulin G and the interaction between double-stranded DNA and the Cas9 RNA complex with limited sequence matches. This analysis routine requires little modification to common experimental protocols, making it readily applicable to existing data and future experiments. PMID- 29457979 TI - Samholides, Swinholide-Related Metabolites from a Marine Cyanobacterium cf. Phormidium sp. AB - Cancer cell cytotoxicity was used to guide the isolation of nine new swinholide related compounds, named samholides A-I (1-9), from an American Samoan marine cyanobacterium cf. Phormidium sp. Their structures were determined by extensive analysis of 1D and 2D NMR spectroscopic data. The new compounds share an unusual 20-demethyl 44-membered lactone ring composed of two monomers, and they demonstrate structural diversity arising from geometric isomerization of double bonds, sugar units with unique glyceryl moieties and varied methylation patterns. All of the new samholides were potently active against the H-460 human lung cancer cell line with IC50 values ranging from 170 to 910 nM. The isolation of these new swinholide-related compounds from a marine cyanobacterium reinvigorates questions concerning the evolution and biosynthetic origin of these natural products. PMID- 29457980 TI - Probing the Chemistry of Adhesion between a 316L Substrate and Spin-on-Glass Coating. AB - Hydrogen silsesquioxane ([HSiO3/2] n)-based "spin-on-glass" has been deposited on a 316L substrate and cured in Ar/H2 gas atmosphere at 600 degrees C to form a continuous surface coating with submicrometer thickness. The coating functionality depends primarily on the adhesion to the substrate, which is largely affected by the chemical interaction at the interface between the coating and the substrate. We have investigated this interface by transmission electron microscopy and electron energy loss spectroscopy. The analysis identified a 5-10 nm thick interaction zone containing signals from O, Si, Cr, and Fe. Analysis of the energy loss near edge structure of the present elements identified predominantly signal from [SiO4]4- units together with Fe2+, Cr2+, and traces of Cr3+. High-resolution transmission electron microscopy images of the interface region confirm a crystalline Fe2SiO4 interfacial region. In agreement with computational thermodynamics, it is proposed that the spin-on-glass forms a chemically bonded silicate-rich interaction zone with the substrate. It was further suggested that this zone is composed of a corundum-type oxide at the substrate surface, followed by an olivine-structure intermediate phase and a spinel-type oxide in the outer regions of the interfacial zone. PMID- 29457981 TI - Reversible Surface Engineering via Nitrone-Mediated Radical Coupling. AB - Efficient and simple polymer conjugation reactions are critical for introducing functionalities on surfaces. For polymer surface grafting, postpolymerization modifications are often required, which can impose a significant synthetic hurdle. Here, we report two strategies that allow for reversible surface engineering via nitrone-mediated radical coupling (NMRC). Macroradicals stemming from the activation of polymers generated by copper-mediated radical polymerization are grafted via radical trapping with a surface-immobilized nitrone or a solution-borne nitrone. Since the product of NMRC coupling features an alkoxyamine linker, the grafting reactions can be reversed or chain insertions can be performed via nitroxide-mediated polymerization (NMP). Poly( n-butyl acrylate) ( Mn = 1570 g.mol-1, D = 1.12) with a bromine terminus was reversibly grafted to planar silicon substrates or silica nanoparticles as successfully evidenced via X-ray photoelectron spectroscopy (XPS), time-of-flight secondary ion mass spectrometry, and grazing angle attenuated total reflection Fourier transform infrared spectroscopy (GAATR-FTIR). NMP chain insertions of styrene are evidenced via GAATR-FTIR. On silica nanoparticles, an NMRC grafting density of close to 0.21 chains per nm2 was determined by dynamic light scattering and thermogravimetric analysis. Concomitantly, a simple way to decorate particles with nitroxide radicals with precise control over the radical concentration is introduced. Silica microparticles and zinc oxide, barium titanate, and silicon nanoparticles were successfully functionalized.

AB - Bruton's tyrosine kinase (Btk) is a nonreceptor cytoplasmic tyrosine kinase involved in B-cell and myeloid cell activation, downstream of B-cell and Fcgamma receptors, respectively. Preclinical studies have indicated that inhibition of Btk activity might offer a potential therapy in autoimmune diseases such as rheumatoid arthritis and systemic lupus erythematosus. Here we disclose the discovery and preclinical characterization of a potent, selective, and noncovalent Btk inhibitor currently in clinical development. GDC-0853 (29) suppresses B cell- and myeloid cell-mediated components of disease and demonstrates dose-dependent activity in an in vivo rat model of inflammatory arthritis. It demonstrates highly favorable safety, pharmacokinetic (PK), and pharmacodynamic (PD) profiles in preclinical and Phase 2 studies ongoing in patients with rheumatoid arthritis, lupus, and chronic spontaneous urticaria. On the basis of its potency, selectivity, long target residence time, and noncovalent mode of inhibition, 29 has the potential to be a best-in-class Btk inhibitor for a wide range of immunological indications. PMID- 29457984 TI - Cardio-oncology: the role of advanced echocardiography in cancer patients. AB - INTRODUCTION: Cardio-oncology is a rapidly growing field aimed at improving the quality of care of cancer patients by preventing and monitoring cardiovascular complications resulting from cancer treatment. Cardiac imaging, and in particular, transthoracic echocardiography, plays an essential?role in the baseline assessment and serial follow-up of cardio-oncology patients. Areas covered: This review article discusses the role of cardiac imaging with a focus on advanced echocardiography for the detection and management of cancer therapy related cardiovascular complications, in particular, left ventricular dysfunction and heart failure. Expert commentary: While traditional imaging based assessment of left ventricular ejection fraction still has its place in cardiac monitoring, more advanced echocardiographic modalities, in particular, myocardial deformation imaging with speckle tracking strain analysis, show great potential for detecting early signs of cardiotoxicity. Larger studies are needed to determine both the clinical role of strain measurement in influencing initiation of cardioprotective agents and its prognostic value in long term outcome.

AB - IFNG (interferon gamma)-induced autophagy plays an important role in the elimination of intracellular pathogens, such as Mycobacterium tuberculosis (Mtb). However, the signaling cascade that leads to the increase in autophagy flux in response to IFNG is poorly defined. Here, we demonstrate that HMOX1 (heme oxygenase 1)-generated carbon monoxide (CO) is required for the induction of autophagy and killing of Mtb residing in macrophages in response to immunomodulation by IFNG. Interestingly, IFNG exposure of macrophages induces an increase in intracellular calcium levels that is dependent on HMOX1 generated CO. Chelation of intracellular calcium inhibits IFNG-mediated autophagy and mycobacterial clearance from macrophages. Moreover, we show that IFNG-mediated increase in intracellular calcium leads to activation of the phosphatase calcineurin (PPP3), which dephosphorylates the TFEB (transcription factor EB) to induce autophagy. PPP3-mediated activation and nuclear translocation of TFEB are critical in IFNG-mediated mycobacterial trafficking and survival inside the infected macrophages. These findings establish that IFNG utilizes the PPP3-TFEB signaling axis for inducing autophagy and regulating mycobacterial growth. We believe this signaling axis could act as a therapeutic target for suppression of growth of intracellular pathogens.

AB - BACKGROUND: In preterm infants, oral stimulation enhances muscle tone and movement which facilitates normal oral motor developmental patterns improving oral feeding performance. AIM: To study the effects on feeding performance, transition to independent oral feeding, weight gain and length of hospital stay of an oral stimulation programme in preterm neonates. STUDY DESIGN: This randomised controlled trial was conducted in a tertiary care teaching hospital over a period of 10 months. Altogether, 102 preterm neonates (30-34 weeks gestation) were randomised into the intervention group (oro-motor stimulation for 5 min twice a day, n = 51) or the control group (routine care only, n = 51). The primary outcome measures were feeding performance, and transition period to reach independent oral feeding. RESULTS: There was better feeding performance (overall intake and rate of milk transfer), shorter transition to independent oral feeding, better weight gain and shorter length of hospital stay in the intervention group (p < 0.001). CONCLUSIONS: Oral stimulation improves feeding performance, weight gain rate and reduces hospital stay in preterm neonates born between 30 and 34 weeks of gestation.

AB - When B lymphocytes encounter antigen-bearing surfaces, B-cell receptor (BCR) signaling initiates remodeling of the F-actin network and reorientation of the microtubule-organizing center (MTOC) towards the antigen contact site. We have previously shown that the Rap1 GTPase, an evolutionarily conserved regulator of cell polarity, is essential for these processes and that Rap1-regulated actin remodeling is required for MTOC polarization. The role of Rap2 proteins in establishing cell polarity is not well understood. We now show that depleting Rap2c, the only Rap2 isoform expressed in the A20 B-cell line, impairs BCR induced MTOC reorientation as well as the actin remodeling that supports MTOC polarization. Thus Rap1 and Rap2 proteins may have similar but non-redundant functions in coupling the BCR to MTOC polarization. PMID- 29457989 TI - Propylthiouracil-induced anti-neutrophil cytoplasmic antibody-associated vasculitis mimicking Kawasaki disease. AB - Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is rare in children and is characterised as necrotising vasculitis predominantly affecting small and medium-sized vessels. Propylthiouracil (PTU), an antithyroid drug, has been implicated in drug-induced AAV. In contrast, Kawasaki disease (KD) is a common systemic vasculitis, typically observed in children, which affects the medium-sized vessels, including the coronary arteries. An 11-year-old girl who developed AAV while receiving PTU therapy for Graves' disease is described. She was admitted to hospital following a 2-day history of fever, cervical adenopathy, cheilitis and papular rash, 3 weeks after an increase in the PTU dose. Despite discontinuation of PTU and the administration of intravenous antibiotic therapy, her clinical condition deteriorated and over the next 2 days she developed severe diarrhoea, conjunctival injection and swelling and redness of the right index finger. Additional findings included liver dysfunction, hydrops of the gallbladder, coagulopathy and urine abnormalities, suggesting glomerulonephritis. She met the diagnostic criteria for KD and received intravenous immunoglobulin (IVIG) combined with prednisolone, with rapid resolution of clinical and laboratory parameters. Peeling of the right index fingertip became evident on Day 12 of admission. Serial ultrasound cardiography demonstrated no evidence of cardiac involvement. A high titre of myeloperoxidase ANCA was detected in the patient's serum on admission, and the titre decreased during the convalescent stage. This case demonstrates that children with PTU associated AAV may present with clinical features mimicking KD, and that IVIG along with corticosteroid therapy may be effective in treating patients with drug induced severe systemic AAV.

PMID- 29457991 TI - Protection of sheep by vaccination against experimental challenge with Leptospira borgpetersenii serovar Hardjo and L. interrogans serovar Pomona. AB - AIMS: To evaluate a multivalent leptospiral and clostridial vaccine for prevention of renal colonisation and urinary shedding in sheep, following experimental challenge with New Zealand strains of Leptospira borgpetersenii serovar Hardjo type Hardjobovis and L. interrogans serovar Pomona. METHODS: Two separate but similarly designed studies were conducted. In both studies, Romney cross lambs, aged 9-11 weeks, were randomly allocated to a vaccinated group and a control group. Vaccinated lambs each received two 1.5-mL S/C doses of a multivalent leptospiral and clostridial vaccine, 4 weeks apart, and animals in the control groups received the same dose of saline. Groups of 12 vaccinated and 12 control lambs were randomly selected in each study for challenge with serovars Hardjo or Pomona. Challenge was initiated 16 weeks following the second vaccination with three daily doses of live leptospires by intranasal and conjunctival routes. Following challenge, urine samples were collected weekly for 6 weeks, for dark field microscopy and leptospiral culture; 6 weeks after challenge the lambs were slaughtered and kidneys collected for leptospiral culture. RESULTS: In lambs challenged with serovar Hardjo, 8/12 unvaccinated lambs had >=1 urine or kidney sample that was positive for leptospires following culture, compared with 0/12 lambs in the vaccinated group (p=0.001). In lambs challenged with serovar Pomona, 9/12 unvaccinated lambs had >=1 urine or kidney sample that was positive following culture, compared with 0/12 lambs in the vaccinated group (p<0.001). Prevention of renal colonisation and urinary shedding, expressed as the prevented fraction, was 100 (95% CI=61.7-100)% and 100 (95% CI=68.3-100)% against challenge with serovars Hardjo and Pomona, respectively, at 4 months after vaccination. CONCLUSIONS AND CLINICAL RELEVANCE: Use of a multivalent leptospiral and clostridial vaccine demonstrated protection against challenge from New Zealand strains of serovars of Hardjo and Pomona 4 months after vaccination in lambs first vaccinated at 9-11 weeks of age. Further studies are required to assess the duration of immunity against challenge in sheep.

AB - The Phlebotomus sand flies are considered an important vector of both canine and human leishmaniasis. Current measures for sand fly control include mostly indoor interventions, such as residual spraying of dwellings (IRS) to target endophilic sand fly species with very limited number of vector control tools for outdoor interventions against exophilic sand flies. In this study we investigated the efficacy of ground ultra low volume (ULV) space spray applications of a deltamethrin based product against field populations of P. perfiliewi, a major nuisance and pathogen-transmitting sand fly species of the Mediterranean Basin. Sand fly flight activity patterns and flight height preference within candidate treatment sites (kennels) were determined prior to treatments in order to optimize the timing and application parameters of the spray applications. On average there was a distinct activity peak between 20.00-22.00 h for both male and female P. perfiliewi with more than 45% and 30% of the population sampled occurring between 20.00-21.00 h and 21.00-22.00 h, respectively. No significant difference was observed in sand fly numbers from sticky traps placed at 0.5 up to 1.5 m height. However, there was a significant decrease in sand fly numbers at 2 m indicating a preference of sand flies to fly below 2 m. The low and high application rate of deltamethrin resulted in mean sand fly population decrease of 18 and 66%, respectively between pre-and post-treatment trap nights. The percent mean population change in the untreated control area was a positive number (30%) indicating that there was an increase in numbers of sand flies trapped between pre- and post-treatment nights. The results of this study provide strong evidence that ground ULV space spray applications when applied properly can result in significant sand fly control levels, even in a heavily infested sand fly environment such as the kennel sites used in this study. PMID- 29457993 TI - Leptospira seroprevalence in animals in the Caribbean region: A systematic review. AB - This systematic review summarises the data published on the Leptospira seroprevalence, serovar diversity and distribution among animal species in the Caribbean region. Following Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, and checklist, relevant articles were identified and data were extracted and recorded. The review provided Leptospira seroprevalence data from 16 Caribbean islands (Barbados, Trinidad, Grenada, Puerto Rico, Saint Croix, St. Kitts and Nevis, Jamaica, Antigua, Carriacou, Dominica, Guadalupe, Martinique, Monserrat, St. Lucia, St. Maarten, and St. Vincent) in a variety of animal species. Reviewing the literature highlighted the limited amount of data available from limited number of islands. Many of the studies conducted have recorded seroprevalences based on variable and small samples sizes. Besides, serovar panels used for MAT were not consistent between studies. The review indicates that the Leptospira exposure in a given geographic location may change with time and climatic and environmental conditions, and highlights the need to conduct continual surveillance in tropical countries where the climate supports the survival of Leptospira in the environment. Specific attention must be given to standardization of MAT panels and protocols and providing training across laboratories involved in testing. Further, animal and environment testing to isolate and identify circulating Leptospira spp. in a geographic region must actively be pursued. This knowledge is important to implement geographically specific control programs, as risk factors of Leptospira transmission is favoured by various factors such as change in climatic conditions, urbanization, encroachment of wildlife inhabitation, import/export of animals, increase in adventure travel, and water related recreational activities. PMID- 29457994 TI - Uric acid and allopurinol aggravate absence epileptic activity in Wistar Albino Glaxo Rijswijk rats. AB - Uric acid has a role in several physiological and pathophysiological processes. For example, uric acid may facilitate seizure generalization while reducing uric acid level may evoke anticonvulsant/antiepileptic effects. Allopurinol blocks the activity of xanthine oxidase, by which allopurinol inhibits catabolism of hypoxanthine to xanthine and uric acid and, as a consequence, decreases the level of uric acid. Although the modulation of serum uric acid level is a widely used strategy in the treatment of certain diseases, our knowledge regarding the effects of uric acid on epileptic activity is far from complete. Thus, the main aim of this study was the investigation of the effect of uric acid on absence epileptic seizures (spike-wave discharges: SWDs) in a model of human absence epilepsy, the Wistar Albino Glaxo/Rijswijk (WAG/Rij) rat. We investigated the influence of intraperitoneally (i.p.) injected uric acid (100 mg/kg and 200 mg/kg), allopurinol (50 mg/kg and 100 mg/kg), a cyclooxygenase 1 and 2 (COX-1 and COX-2) inhibitor indomethacin (10 mg/kg) and inosine (500 mg/kg) alone and the combined application of allopurinol (50 mg/kg) with uric acid (100 mg/kg) or inosine (500 mg/kg) as well as indomethacin (10 mg/kg) with uric acid (100 mg/kg) and inosine (500 mg/kg) with uric acid (100 mg/kg) on absence epileptic activity. We demonstrated that both uric acid and allopurinol alone significantly increased the number of SWDs whereas indomethacin abolished the uric acid-evoked increase in SWD number. Our results suggest that uric acid and allopurinol have proepileptic effects in WAG/Rij rats. PMID- 29457995 TI - Translation and validation of the Transition Readiness Assessment Questionnaire (TRAQ). AB - OBJECTIVE: To translate and validate the Brazilian Portuguese version of the Transition Readiness Assessment Questionnaire in a population of adolescents and young adults with chronic rheumatologic disorders. This questionnaire evaluates the patient's readiness for making the transition from the pediatric health service to adult care. METHODS: The four-phase methodology for the translation and validation of generic questionnaires was followed, including translation, back-translation, pilot testing and clinical validation of the final tool. The confirmatory factor analysis was used for clinical validation and the Cronbach's alpha coefficient was used to assess the overall internal consistency of the final tool. RESULTS: A total of 150 patients with a mean age of 17.0 years (SD=2.2 years, range 14-21 years) were enrolled for the final tool validation. Of those, 71 patients had juvenile systemic lupus erythematosus (47.3%), 64 had juvenile idiopathic arthritis (42.7%), and 15 had juvenile dermatomyositis (10%). During the confirmatory factor analysis, the dimension "Talking with providers" consisting of two questions, was considered as not fitting the translated questionnaire due to a very high ceiling effect and was therefore excluded. All other translated items favorably contributed to the overall consistency of the final tool; removing that dimension did not result in a substantial increase in Cronbach's alpha, which was 0.776. CONCLUSIONS: The Brazilian Portuguese version of the Transition Readiness Assessment Questionnaire was validated in a population of transitional patients with chronic rheumatologic disorders, after one dimension from the original questionnaire was excluded. It is a non-specific disease questionnaire; thus, it can be used to evaluate the transition readiness of Brazilian patients with other chronic diseases. PMID- 29457996 TI - The TyG index cutoff point and its association with body adiposity and lifestyle in children. AB - OBJECTIVE: To investigate the factors associated with insulin resistance in children aged 4-7 years, and to identify the cutoff point of the triglyceride glucose index for the prediction of insulin resistance in this population. METHODS: A cross-sectional study was conducted with 403 children from a retrospective cohort. Insulin resistance was also evaluated in a sub-sample using the HOMA index. Four indicators of body adiposity were assessed: body mass index, waist-to-height ratio, and the percentages of total and central body fat. Food habits were evaluated by the identification of dietary patterns, using principal component analysis. Information was also collected on lifestyle, socioeconomic status, and breastfeeding time. RESULTS: The median index observed in the sample was 7.77, which did not differ between the genders. The shorter the time spent in active activities, the higher the triglyceride-glucose value; and increase in the values of body adiposity indicators was positively associated with triglyceride glucose. The cutoff point with the best balance between sensitivity and specificity values was 7.88 (AUC=0.63, 95% CI: 0.51-0.74). CONCLUSION: The present study identified that total and central body adiposity and shorter time spent in lively activities was positively associated with insulin resistance, evaluated through the triglyceride-glucose index. The cutoff point of 7.88 may be used in this population for insulin resistance risk screening, but caution is required when using it in other populations. PMID- 29457997 TI - Detection of Acute and Long-Term Effects of Concussion: Dual-Task Gait Balance Control Versus Computerized Neurocognitive Test. AB - OBJECTIVE: To examine the acute (within 72h of injury) and long-term (2mo postinjury) independent associations between objective dual-task gait balance and neurocognitive measurements among adolescents and young adults with a concussion and matched controls. DESIGN: Longitudinal case-control. SETTING: Motion analysis laboratory. PARTICIPANTS: A total of 95 participants completed the study: 51 who sustained a concussion (mean age, 17.5+/-3.3y; 71% men) and 44 controls (mean age, 17.7+/-2.9y; 72% men). Participants who sustained a concussion underwent a dual-task gait analysis and computerized neurocognitive testing within 72 hours of injury and again 2 months later. Uninjured controls also completed the same test protocol in similar time increments. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: We compared dual-task gait balance control and computerized neurocognitive test performance between groups using independent samples t tests. Multivariable binary logistic regression models were then constructed for each testing time to determine the association between group membership (concussion vs control), dual-task gait balance control, and neurocognitive function. RESULTS: Medial-lateral center-of-mass displacement during dual-task gait was independently associated with group membership at the initial test (adjusted odds ratio [aOR], 2.432; 95% confidence interval [CI], 1.269-4.661) and 2-month follow up test (aOR, 1.817; 95% CI, 1.014-3.256) tests. Visual memory composite scores were significantly associated with group membership at the initial hour postinjury time point (aOR, .953; 95% CI, .833-.998). However, the combination of computerized neurocognitive test variables did not predict dual-task gait balance control for participants with concussion, and no single neurocognitive variable was associated with dual-task gait balance control at either testing time. CONCLUSIONS: Dual-task assessments concurrently evaluating gait and cognitive performance may allow for the detection of persistent deficits beyond those detected by computerized neurocognitive deficits alone. PMID- 29457998 TI - Home-based Neuromuscular Electrical Stimulation as an Add-on to Pulmonary Rehabilitation Does Not Provide Further Benefits in Patients With Chronic Obstructive Pulmonary Disease: A Multicenter Randomized Trial. AB - OBJECTIVE: To assess the additional effect of a home-based neuromuscular electrical stimulation (NMES) program as an add-on to pulmonary rehabilitation (PR), on functional capacity in subjects with chronic obstructive pulmonary disease (COPD). DESIGN: Single-blind, multicenter randomized trial. SETTING: Three PR centers. PARTICIPANTS: Subjects with severe to very severe COPD (N=73; median forced expiratory volume in 1 second, 1L (25th-75th percentile, 0.8-1.4L) referred for PR. Twenty-two subjects discontinued the study, but only 1 dropout was related to the intervention (leg discomfort). INTERVENTION: Subjects were randomly assigned to either PR plus quadricipital home-based NMES (35Hz, 30min, 5 time per week) or PR without NMES for 8 weeks. MAIN OUTCOME MEASURE: The 6-minute walk test (6MWT) was used to assess functional capacity. RESULTS: Eighty-two percent of the scheduled NMES sessions were performed. In the whole sample, there were significant increases in the distance walked during the 6MWT (P<.01), peak oxygen consumption (P=.02), maximal workload (P<.01), modified Medical Research Council dyspnea scale (P<.01), and Saint George's Respiratory Questionnaire total score (P=.01). There was no significant difference in the magnitude of change for any outcome between groups. CONCLUSIONS: Home-based NMES as an add-on to PR did not result in further improvements in subjects with severe to very severe COPD; moreover, it may have been a burden for some patients.

AB - Mitochondrial ATP-regulated potassium channels are present in the inner membrane of the mitochondria of various cells. In the present study, we show for the first time mitochondrial ATP-regulated potassium channels in human dermal fibroblast cells. Using the patch-clamp technique on the inner mitochondrial membrane of fibroblasts, we detected a potassium channel with a mean conductance equal to 100 pS in symmetric 150 mM KCl. The activity of this channel was inhibited by a complex of ATP/Mg2+ and activated by potassium channel openers such as diazoxide or BMS 191095. Channel activity was inhibited by antidiabetic sulfonylurea glibenclamide and 5-hydroxydecanoic acid. The influence of substances modulating ATP-regulated potassium channel activity on oxygen consumption and membrane potential of isolated fibroblast mitochondria was also studied. Additionally, the potassium channel opener diazoxide lowered the amount of superoxide formed in isolated fibroblast mitochondria. Using reverse transcriptase-PCR, we found an mRNA transcript for the KCNJ1(ROMK) channel. The presence of ROMK protein was observed in the inner mitochondrial membrane fraction. Moreover, colocalization of the ROMK protein and a mitochondrial marker in the mitochondria of fibroblast cells was shown by immunofluorescence. In summary, the ATP-regulated mitochondrial potassium channel in a dermal fibroblast cell line have been identified. PMID- 29458002 TI - The effect of time of day testing and utility of 30 and 60 minute cortisol values in the 250 mcg ACTH stimulation test. AB - BACKGROUND: Despite widespread use of the 250-mcg Cosyntropin test (ACTH test) for the diagnosis of adrenal insufficiency (AI), the effect of time of day and the utility of performing both 30- and 60-min serum cortisol values remains unclear. METHODS: We conducted a retrospective cohort study of all ACTH testing at the Halifax Neuropituitary Program, Nova Scotia, Canada between January 2006 and April 2016. Data were collected on age, gender, medication history, serum cortisol levels at 0, 30 and 60 min after ACTH administration, as well as time of and indication for testing. RESULTS: There were 336 tests performed, divided by time of day (0800-1000 h, 1001-1200 h, and after 1200 h). There were no differences in mean cortisol levels at 30 (574.5, 559, 534 nmol/L, respectively; p = 0.25) and 60 min (642, 623, 619 nmol/L, respectively; p = 0.63) between groups. When comparing 30- vs. 60-min values using a cut-off of >=500 nmol/L, 45 patients (13.4%) failed to reach the cut-off at 30 min but met the cut-off at 60 min. Conversely, only 2 patients (0.6%) who met the cut-off at 30 min failed to reach it at 60 min. CONCLUSION: We found that outcomes from ACTH testing are not affected by time of day. Furthermore, using a 30-min cortisol level in isolation results in more than one in seven patients having a false positive diagnosis of AI; a 60-min value of >=500 nmol/L alone may be sufficient to diagnose AI in >99% of cases. PMID- 29458003 TI - FGF 23, PTH and vitamin D status in end stage renal disease patients affected by VDR FokI and BsmI variants. AB - OBJECTIVES: The aim of this study was to evaluate the association between two VDR SNPs FokI and BsmI and mineral status in ESRD patients. DESIGN AND METHODS: Our case-control study included 100 patients with chronic renal failure in ESRD and 149 healthy subjects. We measured the serum Vitamin D levels and the serum intact PTH level by Electrochemiluminescence Technology (cobas E411 analyzer). We evaluated the serum FGF23 levels by indirect ELISA method. The genotyping of two VDR gene variants FokI and BsmI was carried out by PCR-RFLP technique. RESULTS: In our study, the FokI TT genotype was associated with lower risk of ESRD development (OR = 0.176, Padj = 0.039). The difference in PTH and FGF23 levels between cases and controls was statistically significant. The expression of FokI CT genotype in subjects with diabetic nephropathy was associated with a negative correlation between VD and PTH levels (r = -0.620, P = 0.032) and a positive correlation between VD and FGF23 levels (r = 0.967, P = 0.012). A significant differences in VD levels between patients and controls was observed in the presence of FokI TT (P = 0.044) and CT (P = 0.036) genotypes. The expression of FGF23 serum level was significantly elevated in patients than in controls in the presence of the FokI CC and BsmI AG genotypes. CONCLUSIONS: In conclusion, our study shows the existence of an association between VDR FokI, BsmI polymorphisms and mineral status in ESRD patients. The presence of VDR variants affect the protein expression of VD, phosphorus, FGF23 and PTH. PMID- 29458004 TI - Real-time analysis of cleavage and religation activity of human topoisomerase 1 based on ternary fluorescence resonance energy transfer DNA substrate. AB - Human topoisomerase 1B is a ubiquitous and essential enzyme involved in relaxing the topological state of supercoiled DNA to allow the progression of fundamental DNA metabolism. Its enzymatic catalytic cycle consists of cleavage and religation reaction. A ternary fluorescence resonance energy transfer biosensor based on a suicide DNA substrate conjugated with three fluorophores has been developed to monitor both cleavage and religation Topoisomerase I catalytic function. The presence of fluorophores does not alter the specificity of the enzyme catalysis on the DNA substrate. The enzyme-mediated reaction can be tracked in real-time by simple fluorescence measurement, avoiding the use of risky radioactive substrate labeling and time-consuming denaturing gel electrophoresis. The method is applied to monitor the perturbation brought by single mutation on the cleavage or religation reaction and to screen the effect of the camptothecin anticancer drug monitoring the energy transfer decrease during religation reaction. Pathological mutations usually affect only the cleavage or the religation reaction and the proposed approach represent a fast protocol for assessing chemotherapeutic drug efficacy and analyzing mutant's properties. PMID- 29458005 TI - 14-3-3zeta promotes esophageal squamous cell carcinoma invasion by repressing S1PR2 protein expression through NF-kappaB signaling. AB - 14-3-3zeta is overexpressed in several cancers, including esophageal squamous cell carcinoma (ESCC), and plays an important role in tumorigenesis. However, the mechanisms underlying its tumorigenesis remain unclear. Here we report that 14-3 3zeta was upregulated in ESCC tumors, compared with adjacent normal tissues; 14-3 3zeta levels were positively correlated with ESCC lymph node metastasis and recurrence. Overexpression of 14-3-3zeta promoted the tumor growth and invasion of ESCC in vitro and in vivo, whereas depletion of 14-3-3zeta suppressed these effects. Moreover, 14-3-3zeta reduces expression of genes mediating S1P/S1PR2 signaling, and this effect is mediated through activation of NF- kappa B. Taken together, 14-3-3zeta contributes to ESCC tumorigenesis and progression through repressing S1PR2 signaling and may act as a new therapeutic target for ESCC. PMID- 29458006 TI - Mechanistic studies of formate oxidase from Aspergillus oryzae: A novel member of the glucose-Methanol-choline oxidoreductase enzyme superfamily that oxidizes carbon acids. AB - Formate oxidase (FOX) from Aspergillus oryzae is the only GMC member that oxidizes a carbon acid rather than alcohols; thus, its catalytic mechanism may be different from that of other GMC members. We have used pH, solvent viscosity, and deuterium kinetic isotope effects, to investigate the catalytic mechanism of FOX. The enzyme followed a Bi-Bi sequential steady-state kinetic mechanism. The kcat value was pH-independent between pH 2.8 and 6.8, suggesting a lack of ionizable groups in kinetic step(s) that limit the overall turnover of the enzyme. The kcat/Kformate value decreased from a value of 10,000 M-1s-1 at low pH with a pKa value of 4.4, consistent with the requirement of a protonated group for substrate binding. An inverse viscosity dependence on the kcat/Kformate value indicated an isomerization of the Michaelis complex. The kcat/Koxygen value was 340,000 M-1s-1 and pH independent up to pH 6.0. The Dkcat and D(kcat/Kformate) values were 2.5 and 1.9, respectively, indicating that substrate CH bond cleavage is rate limiting for FOX catalysis. Analytical ultracentrifugation indicated a concentration dependence of the oligomeric state of FOX. The appkred,H value was ~75% that of kcat,H, indicating that the anaerobic reduction of FOX was dependent on the oligomeric state of FOX. PMID- 29458007 TI - A Genomically Characterized Collection of High-Grade Serous Ovarian Cancer Xenografts for Preclinical Testing. AB - High-grade serous ovarian cancer (HGSC) is the leading cause of morbidity and mortality from gynecologic malignant tumors. Overall survival remains low because of the nearly ubiquitous emergence of platinum resistance and the paucity of effective next-line treatments. Current cell culture-based models show limited similarity to HGSC and are therefore unreliable predictive models for preclinical evaluation of investigational drugs. This deficiency could help explain the low overall rate of successful drug development and the decades of largely unchanged approaches to HGSC treatment. We used gene expression, copy number variation, and exome sequencing analyses to credential HGSC patient-derived xenografts (PDXs) as effective preclinical models that recapitulate the features of human HGSC. Mice bearing PDXs were also treated with standard-of-care carboplatin therapy. PDXs showed similar sensitivity to carboplatin as the patient's tumor at the time of sampling. PDXs also recapitulated the diversity of genomic alterations (copy number variation and mutation profiles) previously described in large data sets that profiled HGSC. Furthermore, mRNA profiling showed that the PDXs represent all HGSC subtypes with the exception of the immunoreactive group. Credentialing of PDX models of HGSC should aid progress in HGSC research by providing improved preclinical models of HGSC that can be used to test novel targets and more accurately evaluate their likelihood of success. PMID- 29458009 TI - The Four-and-a-Half LIM Domain Protein 2 Supports Influenza A Virus-Induced Lung Inflammation by Restricting the Host Adaptive Immune Response. AB - Four-and-a-half LIM domain protein 2 (FHL2) is a multifunctional adaptor protein with fine-tuning adjustment properties. It acts as a regulator of signaling cascades but also as a cofactor of transcription and controls several anti inflammatory immune responses. Recently, we described FHL2 as a novel regulator of influenza A virus propagation. We have shown that in vitro FHL2 restricts viral replication by accelerating the interferon regulatory factor 3-dependent transcription of the Ifnb1 gene. In this work, we unraveled an ambiguous role of FHL2 during influenza A virus infection in vivo. Although FHL2 restrained viral replication during the first 24 hours of infection, it significantly delayed viral clearance afterward. Comparison of lung immune status of wild-type and FHL2 knockout mice during influenza virus infection did not acknowledge significant differences in the innate host immune response but revealed an improved migration of dendritic cells from infected lungs into draining lymph nodes as well as increased levels of activated CD8+ T lymphocytes accumulated in the lungs of FHL2 knockout mice. PMID- 29458008 TI - Trefoil Factor 2 Promotes Type 2 Immunity and Lung Repair through Intrinsic Roles in Hematopoietic and Nonhematopoietic Cells. AB - Trefoil factors (TFFs) are small secreted proteins that regulate tissue integrity and repair at mucosal surfaces, particularly in the gastrointestinal tract. However, their relative contribution(s) to controlling baseline lung function or the extent of infection-induced lung injury are unknown issues. With the use of irradiation bone marrow chimeras, we found that TFF2 produced from both hematopoietic- and nonhematopoietic-derived cells is essential for host protection, proliferation of alveolar type 2 cells, and restoration of pulmonary gas exchange after infection with the hookworm parasite Nippostrongylus brasiliensis. In the absence of TFF2, lung epithelia were unable to proliferate and expressed reduced lung mRNA transcript levels for type 2 response-inducing IL 25 and IL-33 after infectious injury. Strikingly, even in the absence of infection or irradiation, TFF2 deficiency compromised lung structure and function, as characterized by distended alveoli and reduced blood oxygen levels relative to wild-type control mice. Taken together, we show a previously unappreciated role for TFF2, produced by either hematopoietic or nonhematopoietic sources, as a pro-proliferative factor for lung epithelial cells under steady state and infectious injury conditions. PMID- 29458010 TI - Galectin-9 Is Critical for Mucosal Adaptive Immunity through the T Helper 17-IgA Axis. AB - Impairment of the intestinal mucosal immunity significantly increases the risk of acute and chronic diseases. IgA plays a major role in humoral mucosal immunity to provide protection against pathogens and toxins in the gut. Here, we investigated the role of endogenous galectin-9, a tandem repeat-type beta-galactoside-binding protein, in intestinal mucosal immunity. By mucosal immunization of Lgals9-/- and littermate control mice, it was found that lack of galectin-9 impaired mucosal antigen-specific IgA response in the gut. Moreover, Lgals9-/- mice were more susceptible to developing watery diarrhea and more prone to death in response to high-dose cholera toxin. The results indicate the importance of galectin-9 in modulating intestinal adaptive immunity. Furthermore, bone marrow chimera mice were established, and galectin-9 in hematopoietic cells was found to be critical for adaptive IgA response. In addition, immunized Lgals9-/- mice exhibited lower expression of Il17 and fewer T helper 17 (Th17) cells in the lamina propria, implying that the Th17-IgA axis is involved in this mechanism. Taken together, these findings suggest that galectin-9 plays a role in mucosal adaptive immunity through the Th17-IgA axis. By manipulating the expression or activity of galectin 9, intestinal mucosal immune response can be altered and may benefit the development of mucosal vaccination.

AB - Tumor invasion is a critical first step in the organismic dissemination of cancer cells and the formation of metastasis in distant organs, the most important prognostic factor and the actual cause of death in most of the cancer patients. We report herein that the cell surface protein podoplanin (PDPN), a potent inducer of cancer cell invasion, is conspicuously expressed by the invasive front of squamous cell carcinomas (SCCs) of the cervix in patients and in the transgenic human papillomavirus/estrogen mouse model of cervical cancer. Laser capture microscopy combined with gene expression profiling reveals that the expression of interferon-responsive genes is up-regulated in PDPN-expressing cells at the tumor invasive front, which are exposed to CD45-positive inflammatory cells. Indeed, PDPN expression can be induced in cultured SCC cell lines by single or combined treatments with interferon-gamma, transforming growth factor-beta, and/or tumor necrosis factor-alpha. Notably, shRNA-mediated ablation of either PDPN or STAT1 in A431 SCC cells repressed cancer cell invasion on s.c. transplantation into immunodeficient mice. The results highlight the induction of tumor cell invasion by the inflammatory cytokine-stimulated expression of PDPN in the outermost cell layers of cervical SCC. PMID- 29458012 TI - KLF10 Gene Expression Modulates Fibrosis in Dystrophic Skeletal Muscle. AB - Dystrophic skeletal muscle is characterized by fibrotic accumulation of extracellular matrix components that compromise muscle structure, function, and capacity for regeneration. Tissue fibrosis is often initiated and sustained through transforming growth factor-beta (TGF-beta) signaling, and Kruppel-like factor 10 (KLF10) is an immediate early gene that is transcriptionally activated in response to TGF-beta signaling. It encodes a transcriptional regulator that mediates the effects of TGF-beta signaling in a variety of cell types. This report presents results of investigation of the effects of loss of KLF10 gene expression in wild-type and dystrophic (mdx) skeletal muscle. On the basis of RT PCR, Western blot, and histological analyses of mouse tibialis anterior and diaphragm muscles, collagen type I (Col1a1) and fibronectin gene expression and protein deposition were increased in KLF10-/- mice, contributing to increased fibrosis. KLF10-/- mice displayed increased expression of genes encoding SMAD2, SMAD3, and SMAD7, particularly in diaphragm muscle. SMAD4 gene expression was unchanged. Expression of the extracellular matrix remodeling genes, MMP2 and TIMP1, was also increased in KLF10-deficient mouse muscle. Histological analyses and assays of hydroxyproline content indicated that the loss of KLF10 increased fibrosis. Dystrophic KLF10-null mice also had reduced grip strength. The effects of loss of KLF10 gene expression were most pronounced in dystrophic diaphragm muscle, suggesting that KLF10 moderates the fibrotic effects of TGF-beta signaling in chronically damaged regenerating muscle. PMID- 29458013 TI - Argonaute 2 RNA Immunoprecipitation Reveals Distinct miRNA Targetomes of Primary Burkitt Lymphoma Tumors and Normal B Cells. AB - miRNAs are small noncoding RNAs involved in the posttranscriptional regulation of gene expression. Deregulated miRNA levels have been linked to Burkitt lymphoma (BL) pathogenesis. To date, the number of known pathogenesis-related miRNA-target gene interactions is limited. Here, we determined for the first time the miRNA targetomes of primary BL tumors and normal B cells. AGO2-RNA immunoprecipitation of two frozen diagnostic BL tissue samples and three CD19+ B-cell samples isolated from routinely removed tonsils showed distinct miRNA targetomes of BL and normal B cells. In contrast to normal B cells, miRNA target genes in BL were enriched for targets of the oncogenic miR-17 to 92 cluster, and were involved mainly in cell cycle and cell death. Immunohistochemistry on BL and tonsil tissues confirmed altered protein levels for two of six selected miRNA targets, in line with the differential AGO2-IP enrichment between BL and normal B cells. A comparison of AGO2-IP-enriched genes in primary BL cases with BL cell lines indicated that despite a considerable overlap, the miRNA targetomes of BL cell lines show substantial differences with the targetomes of primary BL tumors. In summary, we identified distinct miRNA targetomes of BL and normal B cells, and showed both the necessity and feasibility of studying miRNA-target gene interactions in primary tumors. PMID- 29458015 TI - Sulfenamide and sulfonamide derivatives of metformin can exert anticoagulant and profibrinolytic properties. AB - Type 2 diabetes mellitus (T2DM) is characterised not only by hyperglycaemia and insulin resistance but also an impaired balance between the processes of coagulation and fibrinolysis. The aim of this study was to examine the effects of metformin, a widely-used oral anti-diabetic drug, phenformin and eight sulfenamide and sulfonamide derivatives of metformin on several haemostasis parameters. Thrombin Time (TT) tests were performed according to the available commercial method. The activity of factor X was conducted based on deficient plasma factor X. The activity of two main enzymes involved in haemostasis, thrombin and plasmin, was measured spectrophotometrically with chromogenic substrates. Protein C and antithrombin III (AT) activity assays using chromogenic substrates were conducted to determine the effect of the derivatives of metformin on these both naturally occurring anticoagulants. Two of the compounds, sulfenamide with hexyl tail and para-nitro-benzenesulfonamide significantly shortened TT. ortho-nitro sulfonamide at a concentration of 0.3-1.5 MUmol/mL contributed to a significant decrease in the activity of factor X. However, sulfenamides with cyclohexyl, butyl and branched ethyl-hexyl tails at 1.5 of MUmol/mL increased its activity, and simultaneously shortened PT. Additionally, ortho-nitro-benzenesulfonamide at concentrations of 1.5 MUmol/mL was found to significantly decrease reaction velocity (? dA/dt) in the thrombin activity assay. On contrary, it was noticed that branched sulfenamide at the concentration of 1.5 MUmol/mL significantly increased the enzymatic activity of plasmin. Metformin, phenformin and octyl and butyl sulfenamides were associated with a significant increase in the activity of AT. Hexyl sulfenamide and para-nitro- as well as para-trifluoro-ortho-nitro-benzenesulfonamide contributed to the decrease in the activity of protein C, while the other tested compounds did not affect its activity. In conclusion, 2-nitro-benzenesulfonamide derivative of metformin presents highly beneficial anticoagulant properties. This compound is therefore promising candidate for further in vitro and in vivo studies. PMID- 29458014 TI - Topical delivery of l-theanine ameliorates TPA-induced acute skin inflammation via downregulating endothelial PECAM-1 and neutrophil infiltration and activation. AB - l-theanine, the most abundant free amino acid in tea, has been documented to possess many different bioactive properties through oral or intragastrical delivery. However, little is known about the effect of topical delivery of l theanine on acute inflammation. In the present study, by using 12-O tetradecanoylphorbol-13-acetate (TPA, 2.5 MUg/ear)-induced ear edema model in mice, we first found that single-dose local pretreatment of l-theanine 30 min before TPA time- and dose-dependently suppressed the increases in both skin thickness and weight. Subsequently l-theanine ameliorated TPA-induced erythema, vascular permeability increase, epidermal and dermal hyperplasia, neutrophil infiltration and activation via downregulating the expression of PECAM-1 (a platelet endothelial adhesion molecule-1) in blood vessels and the production of pro-inflammatory cytokines IL-1beta, TNF-alpha, and mediator cyclooxygenase-2 (COX-2), which is mainly expressed in neutrophils. It highlighted the potential of l-theanine as a locally administrable therapeutic agent for acute cutaneous inflammation. PMID- 29458016 TI - Renal toxicological evaluations of sulphonated nanocellulose from Khaya sengalensis seed in Wistar rats. AB - Nanocellulose is currently gaining attention due to its unique properties. This attention includes its application as building blocks for developing novel functional materials, plant drug and also in drug delivery systems. However, its safety remains largely untested or less understood. Thus, sulphonated nanocellulose (KSS) was prepared from cellulose (KSC) isolated from Khaya senegalensis seed (KS). KS, KSC and KSS were characterized using Fourier transformed infrared (FTIR), X-ray diffraction (XRD), thermogravimetric analysis (TG), particle size distribution (PSD), zeta potential and scanning electron microscopy (SEM). The impact of KSS on selected renal markers of oxidative stress, inflammation and apoptosis in Wistar rats was also investigated. Thus, male rats were randomly assigned to four groups of five animals each and were treated with KSS (0, 50, 75 and 100 mg/kg BW) for 14 days. Thereafter, biomarkers of renal oxidative damage, inflammation and immunohistochemical expressions of iNOS, COX-2, Bcl-2 and p53 were evaluated. The results revealed KSS to have crystallinity of 70.40%, it was monomodal and has a flaky surface with agglomerations. KSS had no effect on markers of kidney function and oxidative damage, although there was a generalized hypernatremia after 14 days of exposure. Lastly, KSS enhanced the antioxidant status and immunohistochemical expressions of iNOS and COX-2 in the kidney of the rats. While the biomedical applications of KSS may appear plausible, our data suggests that it could induce renal toxicity via the combined impacts of electrolyte imbalance and inflammation. PMID- 29458017 TI - Synergistic and additive effects of ATRA in combination with different anti-tumor compounds. AB - All-trans retinoic acid (ATRA), a derivative of vitamin A, has been shown to potentiate cancer chemotherapy due to its ability to induce signals for cell differentiation or death, and inhibit cell proliferation. The combination of ATRA with taxoids, kinase inhibitors, natural compounds, retinoids, ER or HER2 inhibitors, chemotherapeutic drugs, proteasome inhibitors and nanoformulations of tretinoin have demonstrated additive or synergistic effects in anti-cancer activities. The mechanisms by which the compounds exert their synergistic effects depend on the tumor and the cell type. However, several experiments demonstrated similar mechanisms such as reduction of PCK, c-myc, E2F and Bcl-2, as well as increase of p21 and TGF-beta. When the apoptotic synergistic effect was observed, the predominant effect of ATRA was in differentiation induction. The results indicate that future combinations of ATRA and anti-tumor agents hold promise to enhance and improve anti-carcinogenic therapies. PMID- 29458018 TI - 5-chloro-N4-(2-(isopropylsulfonyl)phenyl)-N2-(2-methoxy-4-(4-((4-methylpiperazin 1-yl)methyl)-1H-1,2,3-triazol-1-yl)phenyl)pyrimidine-2,4-diamine (WY-135), a novel ALK inhibitor, induces cell cycle arrest and apoptosis through inhibiting ALK and its downstream pathways in Karpas299 and H2228 cells. AB - Anaplastic lymphoma kinase (ALK)-positive cancers have rising morbidity and mortality in recent years, and novel chemotherapeutic drugs with no drug resistance and high activity for treating ALK-positive cancers are needed urgently. In this study, we investigated the anti-cancer effect of 5-chloro-N4-(2 (isopropylsulfonyl)phenyl)-N2-(2-methoxy-4-(4-((4-methylpiperazin-1-yl)methyl)-1H 1,2,3-triazol-1-yl)phenyl)pyrimidine-2,4-diamine (WY-135), a novel ALK inhibitor, on nucleophosmin-anaplastic lymphoma kinase (NPM-ALK) positive cancer cell line Karpas299 and echinoderm microtubule associated protein like 4-anaplastic lymphoma kinase (EML4-ALK) positive cancer cell line H2228. In vitro enzyme assay showed that WY-135 had better enzyme inhibitory activity than ceritinib. MTT assay showed that WY-135 had similar inhibitory activity with ceritinib in Karpas299 and H2228 cells. The cell cycle analysis proved that WY-135 induced cell cycle arrest at G1 phase in a dose-dependent manner and subsequently progressed into apoptosis. Real-time PCR analysis revealed that the mRNA level of ALK was significantly reduced in Karpas299 and H2228 cells treatment with WY-135. Furthermore, western blot analysis showed that WY-135 significantly suppressed ALK and its downstream protein expression. Taken together, WY-135 exhibits significant anti-cancer activity through inhibiting ALK and its downstream protein expression, arresting cell cycle and eventually inducing cell apoptosis in Karpas299 and H2228 cells. WY-135 is a promising ALK inhibitor with novel structure that has tremendous potentials for therapeutic treatment of NPM-ALK or EML4-ALK positive cancers. PMID- 29458019 TI - Raffinose from Costus speciosus attenuates lipid synthesis through modulation of PPARs/SREBP1c and improves insulin sensitivity through PI3K/AKT. AB - Among several metabolic disorders, the pathogenesis of insulin resistance is considered to be multifactorial. Raffinose, an oligosaccharide isolated from the rhizome of Costus speciosus showed <=50% inhibition of lipid accumulation in differentiated HepG2 and 3T3-L1 cells through exhibiting partial agonism to PPARgamma, and, an enhanced secretion of adiponectin in 3T3-L1 adipocytes. Raffinose was also observed to attenuate the expression of SREBP1c, ACC and FAS which are involved in the fatty acid synthesis. A corresponding upregulation of PPARalpha and ACO involved in fatty acid oxidation was observed in steatotic HepG2 hepatocytes and 3T3-L1 adipocytes. In vitro evaluation of its anti-diabetic potential showed a dose dependent enhancement of glucose uptake. Investigation of the insulin sensitizing efficacy of Raffinose revealed an increase in Glut4 translocation via phosphorylation of IRbeta/PI3K/Akt in differentiated L6 myocytes and 3T3-L1 preadipocytes. In addition, Raffinose was potentially involved in glycogen synthesis by inhibiting the activation of GSK3beta. Hence, Raffinose could be a useful therapeutic agent for metabolic maladies. PMID- 29458020 TI - CircRNA circ_0067934 promotes tumor growth and metastasis in hepatocellular carcinoma through regulation of miR-1324/FZD5/Wnt/beta-catenin axis. AB - Recently, increasing evidences demonstrate that circular RNAs (circRNAs) exert very important functions in the progression of human cancers. However, the functions and molecular mechanism of circ_0067934 in hepatocellular carcinoma (HCC) are largely unknown. In the present study, we found that the expression of circ_0067934 was significantly upregulated in HCC tissues and cell lines compared to adjacent normal tissues. Furthermore, we showed that circ_0067934 knockdown remarkably suppressed the proliferation, migration and invasion of Hep3B and HuH7 cells while inducing their apoptosis. In terms of mechanism, we found that circ_0067934 directly suppressed miR-1324, which targeted the 3'-UTR of FZD5 mRNA and subsequently downregulated the Wnt/beta-catenin signaling pathway in HCC. Through rescue experiments, we demonstrated that circ_0067934 enhanced the proliferation, migration and invasion of HCC cells by the inhibition of miR-1324 and concomitant activation of FZD5/Wnt/beta-catenin signaling pathway. In summary, the circ_0067934/miR-1324/FZD5/beta-catenin signaling axis might serve as a promising therapeutic target for HCC intervention. PMID- 29458021 TI - Increased mortality from influenza infection in long-chain acyl-CoA dehydrogenase knockout mice. AB - We previously showed that the mitochondrial fatty acid oxidation enzyme long chain acyl-CoA dehydrogenase (LCAD) is expressed in alveolar type II pneumocytes and that LCAD-/- mice have altered breathing mechanics and surfactant defects. Here, we hypothesized that LCAD-/- mice would be susceptible to influenza infection. Indeed, LCAD-/- mice demonstrated increased mortality following infection with 2009 pandemic influenza (A/CA/07/09). However, the mortality was not due to increased lung injury, as inflammatory cell counts, viral titers, and histology scores all showed non-significant trends toward milder injury in LCAD-/ mice. To confirm this, LCAD-/- were infected with a second, mouse-adapted H1N1 virus (A/PR/8/34), to which they responded with significantly less lung injury. While both strains become increasingly hypoglycemic over the first week post infection, LCAD-/- mice lose body weight more rapidly than wild-type mice. Surprisingly, while acutely fasted LCAD-/- mice develop hepatic steatosis, influenza-infected LCAD-/- mice do not. They do, however, become more hypothermic than wild-type mice and demonstrate increased blood lactate values. We conclude that LCAD-/- mice succumb to influenza from bioenergetic starvation, likely due to increased reliance upon glucose for energy. PMID- 29458022 TI - Generation of anti-oligosaccharide antibodies that recognize mammalian glycoproteins by immunization with a novel artificial glycosphingolipid. AB - Here we report a new method for the efficient generation of antibodies that recognize the fine structures of oligosaccharides on glycoproteins. We found a newly designed artificial glycosphingolipid carrying a very long chain fatty acid to be a strong immunogen in mice, with the serum of immunized mice containing antibodies recognizing the oligosaccharide structure of the immunogen. First, we found that conjugation of a simple ceramide analogue to target oligosaccharides could enhance the immunogenicity of these oligosaccharides in these immunized mice. This effect was confirmed in mice immunized with the artificial glycosphingolipids carrying 6'-Sialyl-LacNAc, 3'-Sialyl-LacNAc and LacNAc. Next, we tried to improve the immunogenic enhancing effect of the ceramide analogue. In a model experiment using 6'-Sialyl-LacNAc oligosaccharide, we manipulated the alkyl chains to several lengths, and found that a longer alkyl chain length of the fatty acid correlated with high immunogenicity. Among these we examined, artificial glycosphingolipids conjugated with a ceramide analogue carrying a very long chain fatty acid (lignoceric acid) showed the strongest immunogenicity. By using the artificial glycosphingolipid containing 6'-Sialy-LacNAc and lignoceric acid, we succeeded in the generation of a new anti-6'-Sialyl-LacNAc antibody that recognizes 6'-Sialyl-LacNAc carrying glycoproteins but does not bind to 6' Sialyllactose, asialo-glycoporoteins and glycoproteins carrying 3'-Sialyl-LacNAc. These results indicate that the established technology is valuable for the targeted generation of monoclonal antibodies against glycoproteins containing specific oligosaccharide structures. PMID- 29458023 TI - Structural characterization of the HCoV-229E fusion core. AB - HCoV-229E spike (S) protein mediates virion attachment to cells and subsequent fusion of the viral and cellular membranes. This protein is composed of an N terminal receptor-binding domain (S1) and a C-terminal trans-membrane fusion domain (S2). S2 contains a highly conserved heptad repeat 1 and 2 (HR1 and HR2). In this study, the HRs sequences were designed and connected with a flexible linker. The recombinant fusion core protein was crystallized and its structure was solved at a resolution of 2.45 A. Then we characterized the binding of HR1s and HR2s via both sequence alignment and structural analysis. The overall structures, especially the residues in some positions of HR2 are highly conserved. Fourteen hydrophobic and three polar residues from each HR1 peptide are packed in layers at the coiled-coil interface. These core amino acids can be grouped into seven heptad repeats. Analysis of hydrophobic and hydrophilic interactions between HR2 helix and HR1 helices, shows that the HR1 and HR2 polypeptides are highly complementary in both shape and chemical properties. Furthermore, the available knowledge concerning HCoV-229E fusion core may make it possible to design small molecule or polypeptide drugs targeting membrane fusion, a crucial step of HCoV-229E infection. PMID- 29458024 TI - Spinal cord-specific deletion of the glutamate transporter GLT1 causes motor neuron death in mice. AB - Amyotrophic lateral sclerosis (ALS) is a chronic neurodegenerative disorder characterized by the selective loss of motor neurons. The precise mechanisms that cause the selective death of motor neurons remain unclear, but a growing body of evidence suggests that glutamate-mediated excitotoxicity has been considered to play an important role in the mechanisms of motor neuron degeneration in ALS. Reductions in glutamate transporter GLT1 have been reported in animal models of ALS and the motor cortex and spinal cord of ALS patients. However, it remains unknown whether the reduction in GLT1 has a primary role in the induction of motor neuron degeneration in ALS. Here, we generated conditional knockout mice that lacked GLT1 specifically in the spinal cord by crossing floxed-GLT1 mice and Hoxb8-Cre mice. Hoxb8-Cre/GLT1flox/flox mice showed motor deficits and motor neuron loss. Thus, loss of the glial glutamate transporter GLT1 is sufficient to cause motor neuron death in mice. PMID- 29458025 TI - Cell model for the identification and characterization of prion-like components from Alzheimer brain tissue. AB - Intracerebral injection of brain extracts from Alzheimer's disease (AD) patients into appropriate mouse models was previously found to drastically accelerate the deposition of Abeta amyloid in the recipient animals indicating a prion-like activity. In this study we show that this prion-like activity can be also identified by using a cell culture model of Abeta plaque formation. Analysis of biochemical fractions of AD brain extract indicate that the seeding-activity correlated with the presence of Abeta peptide and Abeta-derived aggregates. In vitro-formed fibrils were also active but their activity was low and depending on the fibril structure and conditions of fibril formation. Our data indicate a conformational basis of the observed seeding effect and suggest the utility of our cell model for further studies on the prion-like activity of AD extracts. PMID- 29458026 TI - Knockdown of fascin-1 expression suppresses cell migration and invasion of non small cell lung cancer by regulating the MAPK pathway. AB - Fascin-1 is a cytoskeletal protein and it can specifically bind to F-actin, it can be abnormally expressed in a variety of solid tumors. Fascin-1 was identified as a factor for poor prognosis in non-small cell lung cancer (NSCLC). However, the relevant molecular mechanisms are not yet fully understood. In this study, the fascin-1 knockdown cells were produced by lentivirus infection, and then cell proliferation, invasion and cell migration assay were used to investigate the role of fascin-1 in NSCLC cells. The MAPK pathway related proteins were determined by western blot. In the current study, lentivirus-mediated fascin-1 knockdown significantly decreased the proliferation of NSCLC cells. Furthermore, fascin-1 silencing partly inhibited cell invasion and migration. Inhibition of fascin-1 decreased the activity of the MAPK pathway. Therefore, targeting fascin 1 may inhibit the growth and metastasis of NSCLC cells, which is a potentially effective therapeutic strategy for treating NSCLC.

PMID- 29458028 TI - Are Portable Stereophotogrammetric Devices Reliable in Facial Imaging? A Validation Study of VECTRA H1 Device. AB - PURPOSE: Modern 3-dimensional (3D) image acquisition systems represent a crucial technologic development in facial anatomy because of their accuracy and precision. The recently introduced portable devices can improve facial databases by increasing the number of applications. In the present study, the VECTRA H1 portable stereophotogrammetric device was validated to verify its applicability to 3D facial analysis. MATERIALS AND METHODS: Fifty volunteers underwent 4 facial scans using portable VECTRA H1 and static VECTRA M3 devices (2 for each instrument). Repeatability of linear, angular, surface area, and volume measurements was verified within the device and between devices using the Bland Altman test and the calculation of absolute and relative technical errors of measurement (TEM and rTEM, respectively). In addition, the 2 scans obtained by the same device and the 2 scans obtained by different devices were registered and superimposed to calculate the root mean square (RMS; point-to-point) distance between the 2 surfaces. RESULTS: Most linear, angular, and surface area measurements had high repeatability in M3 versus M3, H1 versus H1, and M3 versus H1 comparisons (range, 82.2 to 98.7%; TEM range, 0.3 to 2.0 mm, 0.4 degrees to 1.8 degrees ; rTEM range, 0.2 to 3.1%). In contrast, volumes and RMS distances showed evident differences in M3 versus M3 and H1 versus H1 comparisons and reached the maximum when scans from the 2 different devices were compared. CONCLUSION: The portable VECTRA H1 device proved reliable for assessing linear measurements, angles, and surface areas; conversely, the influence of involuntary facial movements on volumes and RMS distances was more important compared with the static device.

PMID- 29458034 TI - Fluorescence-linked immunosorbent assay for detection of phenanthrene and its homolog. AB - A competitive fluorescence-linked immunosorbent assay (FLISA) was developed using rhodamine B isothiocyanate (RBITC) as the model fluorescent dye conjugate monoclonal antibody (McAb) for detection of Phe and its homolog (acenaphthene, fluorene, fluoranthene, pyrene and indeno [1,2,3-cd] pyrene) in water samples. The detection range of the assay for Phe was from 2.10 to 91.95 ng/mL. The limit of detection was 1.05 ng/mL, which was approximately 2-fold lower than that of traditional ic-ELISA. Compared with traditional ic-ELISA, more than 70 min was saved because of only one immunoreaction step was needed to accomplish the assay. The average recoveries of Phe and its homolog from domestic water, contaminated water and natural water were 100.7%, 100.8% and 101.2% respectively. The accuracy and precision of the developed FLISA were validated with GC-MS/MS. There were good correlation between the two methods from tap water, contaminated water and river water samples were 0.9994, 0.9935 and 0.9967, respectively. The results suggested that the proposed FLISA could be a potential alternative format for rapid, sensitive, and quantitative detection of Phe and its homolog in environmental water. PMID- 29458035 TI - Lectin-carbohydrate complex evaluation by chemiluminescence. AB - In order to characterize the affinity between specific carbohydrate-binding proteins such as lectins, a model is proposed to study these interactions using a polysaccharide membrane to simulate such adsorption. Here, lectin-carbohydrate interactions were chemiluminescently investigated using lectins conjugated to acridinium ester (AE) and polysaccharides composed of their respective specific carbohydrates. The lectin-AE conjugates were incubated with discs (0.0314-0.6358 cm2) of phytagel, chitosan and carrageenan. The complex formation chemiluminescently detected followed the Langmuir isotherm from which constants were estimated. The association constant (Ka) and maximum binding sites on the membranes were 2.4 * 10-7 M-1 +/- 0.8 * 10-7 M-1 and 1.3 * 10-3 mol. mg-1 +/- 0.3 * 10-3 mol. mg-1 (Con A); 0.9 * 10-6 M-1 +/- 0.4 * 10-6 M-1 and 0.021 * 10-3 mol. mg-1 +/- 0.003 * 10-3 mol. mg-1 (WGA) and 2.0 * 10-6 M-1 +/- 0.9 * 10-6 M-1 and 0.069 * 10-3 mol. mg-1 +/- 0.010 * 10-3 mol. mg-1 (PNA). The proposed model might be useful to study binding affinity and estimate the amount of binding not limited by the sugar content in the membrane. PMID- 29458037 TI - Distinguishing Keratoconic Eyes and Healthy Eyes Using Ultrahigh-Resolution Optical Coherence Tomography-Based Corneal Epithelium Thickness Mapping. AB - PURPOSE: To find differences in epithelial thickness (ET) maps of eyes with keratoconus (KC) and healthy eyes. DESIGN: Institutional cross-sectional study. METHODS: In this study 40 keratoconic eyes and 76 healthy eyes were scanned using a custom-built ultrahigh-resolution optical coherence tomography system. Automated segmentation ET maps with 17 subsectors were calculated (central, temporal inferior, temporal superior, nasal inferior, and nasal superior area). The thinnest point of the epithelium (minET), the thickest point of the epithelium (maxET), and the thinnest point diagonally opposing the thickest point (ETmax/op) were additional parameters. Ratios were calculated as follows: minET/diagonally opposing point (R1), maxET/diagonally opposing point (R2), inferior temporal area/superior nasal area (RTI/NS), and inferior/superior hemisphere (RI/S). Furthermore, collected parameters were analyzed regarding their diagnostic accuracy (area under the curve; AUC). RESULTS: Statistically significant differences were as follows: central ET, 46.25 +/- 2.56/50.91 +/- 1.66; minET, 38.50 +/- 2.10/46.79 +/- 1.27; ETmax/op, 47.14 +/- 2.45/49.60 +/- 1.57; temporal inferior area: 43.93 +/- 2.95/51.04 +/- 1.51 (all mean +/- standard deviation, MUm); R1, 0.76 +/- 0.09/0.93 +/- 0.04; R2, 1.08 +/- 0.04/1.21 +/- 0.16; RTI/NS, 0.85 +/- 0.08/1.02 +/- 0.04; RI/S: 0.92 +/- 0.07/0.99 +/- 0.02. AUC values were R1: 0.979 (confidence interval [CI]: 0.957-1.000), RTI/NS: 0.977 (CI: 0.951-1.000), and minET: 0.928 (CI: 0.880-0.977). CONCLUSIONS: Epithelial thickness maps could clearly visualize different ET patterns. Parameters with the highest potential of diagnostic discrimination between eyes with KC and healthy eyes were, in descending order, R1, RTI/NS, and minET. Consequently, epithelial thickness irregularity and asymmetry seem to be the most promising diagnostic factor in terms of discriminating between keratoconic eyes and healthy eyes.

DESIGN: Retrospective case-control study. METHODS: Patients with nonthrombosed distensible venous malformations of the orbit and patients with other histologically-proven orbital tumors were selected for chart review. The main outcome measure was the apparent diffusion coefficient of these lesions. RESULTS: Sixty-seven patients qualified for chart review; 9 patients had nonthrombosed distensible venous malformations and 58 patients had other histologically-proven tumors. Three of the 9 patients with nonthrombosed distensible venous malformations were initially misdiagnosed as having had solid orbital tumors. The mean apparent diffusion coefficient of distensible venous malformations was 2.80 +/- 0.48 * 10-3 mm2/s, whereas the mean apparent diffusion coefficient of other histologically-proven tumors was 1.18 +/- 0.39 * 10-3 mm2/s (P < .001). The mean apparent diffusion coefficient ranged from 2.42 to 3.94 * 10 3 mm2/s in the distensible venous malformation group, whereas other histologically-proven tumors ranged from 0.53 to 2.08 * 10-3 mm2/s. Therefore, in this single-institution series, a threshold value of 2.10 * 10-3 mm2/s was 100% sensitive and 100% specific for distensible venous malformations. CONCLUSION: Certain nonthrombosed distensible venous malformations can evade diagnostic suspicion and mimic solid orbital tumors on standard magnetic resonance imaging sequences. In this single-institution series, diffusion-weighted imaging effectively distinguished these nonthrombosed distensible venous malformations from other orbital tumors.

AB - Our previous studies have shown that alpha1-adrenoceptors, in addition to alpha2 adrenoceptors, are involved in enhanced contraction of cutaneous blood vessels during cooling. The present study aimed to elucidate the mechanism underlying it. In tail and iliac arteries isolated from rats, isometric contraction was measured using a myograph and the phosphorylation level of myosin phosphatase target subunit 1 (MYPT1) was quantified by western blotting. The phenylephrine-induced contraction was enhanced by cooling to 24 degrees C in tail arteries, but was suppressed in iliac arteries. Endothelium denudation or treatment with iberiotoxin enhanced the phenylephrine-induced contraction in tail arteries at 37 degrees C; however, neither affected the contraction at 24 degrees C. The phenylephrine-induced contraction at 37 degrees C was largely suppressed by nifedipine in iliac arteries, but only slightly in tail arteries. The Rho kinase inhibitor H-1152 largely suppressed the phenylephrine-induced contraction at 24 degrees C, but only slightly at 37 degrees C, in both arteries. The phosphorylation level of MYPT1 at Thr855 in tail arteries was increased by the cooling. Taken together, these results suggest the following mechanism in regard to cooling-induced enhancement of alpha1-adrenoceptor-mediated contraction in tail arteries: Cooling enhances the contraction of tail arteries via alpha1 adrenoceptor stimulation by reducing endothelium-dependent, large-conductance Ca2+-activated K+ channel-mediated relaxation and by inducing Rho kinase-mediated Ca2+ sensitization, although the latter occurs even in iliac arteries. A smaller contribution of voltage-dependent Ca2+ channels, which are largely suppressed by cooling, to alpha1-adrenoceptor-mediated contraction in tail arteries seems to be more crucially involved in the appearance of the enhanced contractile response to cooling.

AB - INTRODUCTION: Diagnostic relevance of plasma amyloid beta (Abeta) for Alzheimer's disease (AD) process yields conflicting results. The objective of the study was to assess plasma levels of Abeta42 and Abeta40 in amnestic mild cognitive impairment (MCI), nonamnestic MCI, and AD patients and to investigate relationships between peripheral and central biomarkers. METHODS: One thousand forty participants (417 amnestic MCI, 122 nonamnestic MCI, and 501 AD) from the Biomarker of AmyLoid pepTide and AlZheimer's diseAse Risk multicenter prospective study with cognition, plasma, cerebrospinal fluid (CSF), and magnetic resonance imaging assessments were included. RESULTS: Plasma Abeta1-42 and Abeta1-40 were lower in AD (36.9 [11.7] and 263 [80] pg/mL) than in amnestic MCI (38.2 [11.9] and 269 [68] pg/mL) than in nonamnestic MCI (39.7 [10.5] and 272 [52] pg/mL), respectively (P = .01 for overall difference between groups for Abeta1-42 and P = .04 for Abeta1-40). Globally, plasma Abeta1-42 correlated with age, Mini-Mental State Examination, and APOE epsilon4 allele. Plasma Abeta1-42 correlated with all CSF biomarkers in MCI but only with CSF Abeta42 in AD. DISCUSSION: Plasma Abeta was associated with cognitive status and CSF biomarkers, suggesting the interest of plasma amyloid biomarkers for diagnosis purpose. PMID- 29458040 TI - Pharmacological inhibition of JAK3 enhances the antitumor activity of imatinib in human chronic myeloid leukemia. AB - Imatinib (IMA) is the standard treatment for CML; however, stopping IMA sometimes results in disease relapse, which suggests that leukemic stem cells (LSCs) remain in such patients, even after complete molecular remission has been achieved. Therefore, new strategies will be required to eradicate LSCs. The Janus kinase signal transducer and activator of transcription (JAK-STAT) pathway is part of the BCR-ABL signaling network, and it is activated in CML, especially in LSCs. JAK2 is known to be associated with CML survival, but the role of JAK3 in CML remains unknown. The antitumor effects of IMA and a JAK3 inhibitor, tofacitinib were examined using the MTT assay in K562 and KCL22. To investigate the mechanisms of action of IMA and the JAK inhibitors in CML cells, we examined apoptosis, the cell cycle, and JAK-STAT signaling using flow cytometry, immunofluorescent microscopy, and Western blotting. The pharmacological inhibition of JAK3 by tofacitinib synergistically enhanced the antitumor effects of IMA in CML cells. Furthermore, the administration of IMA plus a JAK inhibitor reduced the expression of stem cells markers, such as ABCG2 and ALDH1A1. Co blocking JAK3 with IMA and a JAK3 inhibitor might represent a new treatment strategy for eradicating LSCs and preventing CML relapses. PMID- 29458041 TI - Role of superoxide ion formation in hypothermia/rewarming induced contractile dysfunction in cardiomyocytes. AB - Rewarming following accidental hypothermia is associated with circulatory collapse due primarily to impaired cardiac contractile (systolic) function. Previously, we found that reduced myofilament Ca2+ sensitivity underlies hypothermia/rewarming (H/R)-induced cardiac contractile dysfunction. This reduced Ca2+ sensitivity is associated with troponin I (cTnI) phosphorylation. We hypothesize that H/R induces reactive oxygen species (ROS) formation in cardiomyocytes, which leads to cTnI phosphorylation and reduced myofilament Ca2+ sensitivity. To test this hypothesis, we exposed isolated rat cardiomyocytes to a 2-h period of severe hypothermia (15 degrees C) followed by rewarming (35 degrees C) with and without antioxidant (TEMPOL) treatment. Simultaneous measurements of cytosolic Ca2+ ([Ca2+]cyto) and contractile (sarcomere shortening) responses indicated that H/R-induced contractile dysfunction and reduced Ca2+ sensitivity was prevented in cardiomyocytes treated with TEMPOL. In addition, TEMPOL treatment blunted H/R-induced cTnI phosphorylation. These results support our overall hypothesis and suggest that H/R disrupts excitation contraction coupling of the myocardium through a cascade of event triggered by excessive ROS formation during hypothermia. Antioxidant treatment may improve successful rescue of accidental hypothermia victims.

AB - Sperm cryopreservation is challenging, often resulting in irreversible damage to spermatozoa, as indicated by decreased motility, viability, and/or acrosomal integrity. Developing cryopreservation protocols for gametes of endangered species compounds the complexity of technique optimization; samples are difficult to obtain and numbers are limited. Cryopreservation of sperm collected from the critically endangered addra gazelle (Nanger dama ruficollis), a member of the Bovidae family, resulted in significant loss of motility, which was prevented by pretreatment with cholesterol-loaded cyclodextrin (CLC). This study investigated the proteome of sperm (fresh and cryopreserved), processed in the absence and presence of 0.5 mg/ml CLC in the addra gazelle. The proteome of Bos taurus, the closest domestic relative, was used as a reference. Mass spectrometry analysis of the addra gazelle sperm proteome revealed 287 proteins. The concentrations of 85 proteins differed between fresh and frozen/thawed samples; nearly all were decreased. Most were associated with metabolic processes, specifically glycolysis, which may explain the decrease in post-thaw motility observed in this species. CLC pretreatment partially prevented the loss of various proteins involved in metabolism including CAPZB (gene = CAPZB), HS90A (gene = HSP90AA1), and PGAM2 (gene = PGAM2). To our knowledge, this is the first study to evaluate the proteome of any wild bovids' sperm, and the first to compare protein levels in sperm pretreated with CLC. PMID- 29458043 TI - Optimization of a protective medium for enhancing the viability of freeze-dried Bacillus amyloliquefaciens B1408 based on response surface methodology. AB - Response surface methodology (RSM) is a commonly used system to optimize cryoprotectants of biocontrol strains when they are subjected to preparations. Various kinds of cryoprotectants and centrifugal conditions were tested to improve the survival of biocontrol agents after freeze-drying. To determine the optimum levels of incorporation of three cryoprotectants (glucose, trehalose and xylitol) in the freeze-drying process of strain Bacillus amyloliquefaciens B1408, a range of experiments based on Box-Behnken Design (BBD) were conducted. The results indicated that the suitable centrifugation conditions were 5000 r/min,10 min and the optimum concentrations of cryoprotectants were glucose 1.00%, trehalose 4.74% and xylitol 1.45%. The proven survival rate of cells after freeze drying was 91.24%. These results convincingly demonstrated that freeze-drying could be used to preparation of biocontrol strain B1408. This study provides a theoretical basis for commercial possibilities and formulation development. PMID- 29458044 TI - Cryoprotective effect of antifreeze polyamino-acid (Carboxylated Poly-l-Lysine) on bovine sperm: A technical note. AB - In this study, investigating Carboxylated Poly-l-Lysine (CPLL) for its effectiveness as a new cryoprotectant for bovine sperm is aimed. CPLL is an ampholytic polymer compound, has cryoprotective properties similar to those of anti-freeze protein. The cryopreservation medium used for control group consisted of 6.5% (v/v) glycerol, the cryopreservation medium used for experimental group consisted of 3.25% (v/v) glycerol + 0.5% (w/v) CPLL. There was no consequential difference in sperm motility parameter after thawing whereas there was huge distinction for sperm membrane integrity rate (control vs experimental; 49.6 vs 60.7%, P < 0.01). Conception rate of artificial insemination of experimental group was significantly higher than that of control group (79.0% vs 53.1%, P < 0.01). These results suggest CPLL has protected sperm membrane and leads to improve fertility. This is the first report using CPLL for bovine sperm cryopreservation, it is also expected CPLL can be applied to other animal species. PMID- 29458045 TI - Aldose reductase inhibitor, fidarestat prevents doxorubicin-induced endothelial cell death and dysfunction. AB - Despite doxorubicin (Dox) being one of the most widely used chemotherapy agents for breast, blood and lung cancers, its use in colon cancer is limited due to increased drug resistance and severe cardiotoxic side effects that increase mortality associated with its use at high doses. Therefore, better adjuvant therapies are warranted to improve the chemotherapeutic efficacy and to decrease cardiotoxicity. We have recently shown that aldose reductase inhibitor, fidarestat, increases the Dox-induced colon cancer cell death and reduces cardiomyopathy. However, the efficacy of fidarestat in the prevention of Dox induced endothelial dysfunction, a pathological event critical to cardiovascular complications, is not known. Here, we have examined the effect of fidarestat on Dox-induced endothelial cell toxicity and dysfunction in vitro and in vivo. Incubation of human umbilical vein endothelial cells (HUVECs) with Dox significantly increased the endothelial cell death, and pre-treatment of fidarestat prevented it. Further, fidarestat prevented the Dox-induced oxidative stress, formation of reactive oxygen species (ROS) and activation of Caspase-3 in HUVECs. Fidarestat also prevented Dox-induced monocyte adhesion to HUVECs and expression of ICAM-1 and VCAM-1. Fidarestat pre-treatment to HUVECs restored the Dox-induced decrease in the Nitric Oxide (NO)-levels and eNOS expression. Treatment of HUVECs with Dox caused a significant increase in the activation of NF-kappaB and expression of various inflammatory cytokines and chemokines which were prevented by fidarestat pre-treatment. Most importantly, fidarestat prevented the Dox-induced mouse cardiac cell hypertrophy and expression of eNOS, iNOS, and 3-Nitrotyrosine in the aorta tissues. Further, fidarestat blunted the Dox-induced expression of various inflammatory cytokines and chemokines in vivo. Thus, our results suggest that by preventing Dox-induced endothelial cytotoxicity and dysfunction, AR inhibitors could avert cardiotoxicity associated with anthracycline chemotherapy. PMID- 29458046 TI - BMP-2 induces angiogenesis by provoking integrin alpha6 expression in human endothelial progenitor cells. AB - Bone morphogenetic protein-2 (BMP-2) is a multifunctional cytokine, capable of governing several cellular functions, including proliferation, motility, differentiation, and angiogenesis. Circulating endothelial progenitor cells (EPCs) have been shown to facilitate tissue repair, postnatal neovascularization, and tumor associated angiogenesis. Nevertheless, the impact of BMP-2 on angiogenesis of human EPCs has largely remained a mystery. In this study, we found that BMP-2 promoted cell migration and tube formation of EPCs in a concentration-dependent manner, indicating BMP-2 induced in vitro angiogenesis in human EPCs. Furthermore, BMP-2 significantly increased microvessel formation in Matrigel plug assay, and BMP-2 antagonist noggin prevented BMP-2-induced in vivo angiogenesis. Mechanistic investigations showed BMP-2 profoundly induced the expression of Id-1 and integrin alpha6 as well as EPCs angiogenesis by activating PI3K/Akt and MEK/ERK signaling pathways. Moreover, knockdown of Id-1 and integrin alpha6 by siRNA transfection obviously attenuated BMP-2-indueced tube formation of EPCs. These results suggest that BMP-2 promotes angiogenesis in human EPCs through the activation of PI3K/Akt, MEK/ERK, and Id-1/integrin alpha6 signaling cascades. This is the first demonstration that BMP-2 exhibits the angiogenesis property on human EPCs. BMP-2 might serve as the potential therapeutic target for treatment of angiogenesis-related diseases. PMID- 29458048 TI - 4-Phenylbutyric acid protects against lipopolysaccharide-induced bone loss by modulating autophagy in osteoclasts. AB - 4-Phenylbutyric acid (4-PBA) has been used clinically to treat urea cycle disorders and is known to be an inhibitor of endoplasmic reticulum (ER) stress. We hypothesized that 4-PBA attenuates inflammatory bone loss by inducing autophagy, a process that is frequently accompanied by ER stress. Micro computerized tomography analysis showed that 4-PBA attenuated LPS-induced bone loss in mice. The increased area of TRAP-positive osteoclasts (OCs) and serum level of collagen type I fragments in lipopolysaccharide (LPS)-treated mice were also decreased when 4-PBA was administered, suggesting a protective role of 4-PBA in OCs. In vitro, 4-PBA significantly reduced OC area without affecting the number of OCs induced by LPS and decreased bone resorption upon LPS stimulation. LPS-induced autophagy was attenuated by 4-PBA in OCs, as demonstrated by reduced LC3II accumulation, increased p62 level, and reduction in AVO-containing cells. Silencing of autophagy-related protein 7 attenuated the effects of 4-PBA on OC size and fusion. Moreover, 4-PBA reduced nuclear factor-kappaB (NF-kappaB) DNA binding upon LPS stimulation of OCs. Inhibition of NF-kappaB activation diminished the inhibitory effect of 4-PBA on LPS-stimulated changes in LC3II level, OC area, and OC fusion, implying that the effects of 4-PBA on OCs are due at least in part to inhibition of NF-kappaB. These data demonstrate that 4-PBA attenuates LPS-induced bone loss by reducing autophagy in OCs. Our data highlight the therapeutic potential of 4-PBA for ameliorating inflammatory bone loss. PMID- 29458047 TI - Effects of cytochrome P450 single nucleotide polymorphisms on methadone metabolism and pharmacodynamics. AB - Methadone is a synthetic, long-acting opioid with a single chiral center forming two enantiomers, (R)-methadone and (S)-methadone, each having specific pharmacological actions. Concentrations of (R)- and (S)-methadone above therapeutic levels have the ability to cause serious, life-threatening, and fatal side effects. This toxicity can be due in part to the pharmacogenetics of an individual, which influences the pharmacokinetic and pharmacodynamic properties of the drug. Methadone is primarily metabolized in the liver by cytochrome P450 (CYP) enzymes, predominately by CYP2B6, followed by CYP3A4, 2C19, 2D6, and to a lesser extent, CYP2C18, 3A7, 2C8, 2C9, 3A5, and 1A2. Single nucleotide polymorphisms (SNPs) located within CYPs have the potential to play an important role in altering methadone metabolism and pharmacodynamics. Several SNPs in the CYP2B6, 3A4, 2C19, 2D6, and 3A5 genes result in increases in methadone plasma concentrations, decreased N-demethylation, and decreased methadone clearance. In particular, carriers of CYP2B6*6/*6 may have a greater risk for detrimental adverse effects, as methadone metabolism and clearance are diminished in these individuals. CYP2B6*4, on the other hand, has been observed to decrease plasma concentrations of methadone due to increased methadone clearance. The involvement, contribution, and understanding the role of SNPs in CYP2B6, and other CYP genes, in methadone metabolism can improve the therapeutic uses of methadone in patient outcome and the development of personalized medicine.

PMID- 29458050 TI - Investigation of metabolic stability of the novel ALK inhibitor brigatinib by liquid chromatography tandem mass spectrometry. AB - Brigatinib (BGB) belongs to a class of drugs called ALK inhibitor. On April 28, 2017, BGB has been approved by U.S. FDA for use in metastatic ALK-positive NSCLC. A fast, specific, sensitive and validated LC-MS/MS method was developed for the quantification of BGB in human plasma matrix. This method was applied successfully to study metabolic stability of BGB. Reversed phase (C18 column) and isocratic binary mobile phase (55% 0.1% formic acid: 45% ACN) were used for chromatographic separation of BGB and ponatinib (IS). The flow rate, total run time and injection volume were fixed at 0.2 mL/min, 4 min, 5 MUL respectively. ESI source was utilized for ions formation, while multiple reaction monitoring (MRM) mode was used for ion analysis. In human plasma matrix, the Linearity range of the calibration curve was 5-500 ng/mL (r2 >= 0.9982). LOQ and LOD were found to be 1.89 and 5.72 ng/mL. The precision and accuracy for the intra-day and inter day were 0.45 to 1.85% and 97.37 to 104.85%. In vitro half-life (t1/2) and intrinsic clearance (CLint) were equal to 12.0 min and 13.1 +/- 0.15 mL/min/kg respectively. The quantification of BGB in human plasma or its metabolic stability has not been studied as seen in literature review. PMID- 29458051 TI - Elevated systemic zonula occludens 1 is positively correlated with inflammation in cirrhosis. AB - BACKGROUND/AIM: It has been well established that disruption of the intestinal barrier function and increased intestinal permeability contribute to endotoxemia and associated liver injury in patients with cirrhosis. However, the relationship between systemic inflammation and tight junction protein in cirrhosis remain unidentified. The aim of this study was to assess and compare the blood concentrations of ZO-1 with systemic hsCRP in patients with cirrhosis and healthy individuals. METHODS: 30 cirrhotic patients and 30 healthy individuals were enrolled in the study. Blood ZO-1 and hsCRP were measured by ELISA and biochemical parameters by AU680 Beckman Coulter (USA) autoanalyser. RESULTS: The serum ALT, AST, bilirubin, gamma GT, ALP and ammonia were significantly (P < 0.0001) elevated whilst serum albumin concentration was decreased in cirrhotic patients when compared to healthy individuals. Systemic tight junction protein ZO 1 concentration [590.0 +/- 32.79 vs. 349.9 +/- 18.76 pg/ml, respectively; P < 0.0001] and hsCRP [10.50 +/- 1.05 vs 5.31 +/- 0.65 mg/L, respectively; P < 0.001] were significantly elevated in patients with cirrhosis compared to controls. Significant positive correlation was found between increased ZO-1 and hsCRP (r = 0.2680 P < 0.01). CONCLUSION: Our results suggested that increased systemic ZO-1 concentration was associated with inflammation in cirrhosis. Thus, elevated blood ZO-1 levels could be a prognostic marker of cirrhotic patients with intestinal TJ disruption on the background of inflammation. PMID- 29458052 TI - Regulation of proliferation and functioning of transplanted cells by using herpes simplex virus thymidine kinase gene in mice. AB - Though cell transplantation is becoming an attractive therapeutic method, uncontrolled cell proliferation or overexpression of cellular functions could cause adverse effects. These unfavorable outcomes could be avoided by regulating the proliferation or functioning of transplanted cells. In this study, we used a combination of the herpes simplex virus thymidine kinase (HSVtk) gene, a suicide gene, and ganciclovir (GCV) to control the proliferation and functioning of insulin-secreting cells after transplantation in diabetic mice. Mouse pancreatic beta cell line MIN6 cells were selected as insulin-secreting cells for transfection with the HSVtk gene to obtain MIN6/HSVtk cells. Proliferation of MIN6/HSVtk cells was suppressed by GCV in a concentration-dependent manner; 0.25 MUg/mL GCV maintained a constant number of MIN6/HSVtk cells for at least 16 days. MIN6 or MIN6/HSVtk cells were then transplanted to streptozotocin-induced diabetic mice. Mice transplanted with MIN6 cells exhibited hypoglycemia irrespective of GCV administration. In contrast, normal (around 150 mg/dL) blood glucose levels were maintained in mice transplanted with MIN6/HSVtk cells by a daily administration of 50 mg/kg of GCV. These results indicate that controlling the proliferation and functioning of HSVtk gene-expressing cells by GCV could greatly improve the usefulness and safety of cell-based therapy. PMID- 29458053 TI - Circulating bile acids in healthy adults respond differently to a dietary pattern characterized by whole grains, legumes and fruits and vegetables compared to a diet high in refined grains and added sugars: A randomized, controlled, crossover feeding study. AB - OBJECTIVE: The effects of diets high in refined grains on biliary and colonic bile acids have been investigated extensively. However, the effects of diets high in whole versus refined grains on circulating bile acids, which can influence glucose homeostasis and inflammation through activation of farnesoid X receptor (FXR) and G protein-coupled bile acid receptor 1 (TGR5), have not been studied. MATERIALS AND METHODS: We conducted a secondary analysis from a randomized controlled crossover feeding trial (NCT00622661) in 80 healthy adults (40 women/40 men, age 18-45 years) from the greater Seattle Area, half of which were normal weight (BMI 18.5-25.0 kg/m2) and half overweight to obese (BMI 28.0-39.9 kg/m2). Participants consumed two four-week controlled diets in randomized order: 1) a whole grain diet (WG diet), designed to be low in glycemic load (GL), high in whole grains, legumes, and fruits and vegetables, and 2) a refined grain diet (RG diet), designed to be high GL, high in refined grains and added sugars, separated by a four-week washout period. Quantitative targeted analysis of 55 bile acid species in fasting plasma was performed using liquid chromatography tandem mass spectrometry. Concentrations of glucose, insulin, and CRP were measured in fasting serum. Linear mixed models were used to test the effects of diet on bile acid concentrations, and determine the association between plasma bile acid concentrations and HOMA-IR and CRP. Benjamini-Hochberg false discovery rate (FDR) < 0.05 was used to control for multiple testing. RESULTS: A total of 29 plasma bile acids were reliably detected and retained for analysis. Taurolithocholic acid (TLCA), taurocholic acid (TCA) and glycocholic acid (GCA) were statistically significantly higher after the WG compared to the RG diet (FDR < 0.05). There were no significant differences by BMI or sex. When evaluating the association of bile acids and HOMA-IR, GCA, taurochenodeoxycholic acid, ursodeoxycholic acid (UDCA), 5beta-cholanic acid-3beta,12alpha-diol, 5-cholanic acid-3beta-ol, and glycodeoxycholic acid (GDCA) were statistically significantly positively associated with HOMA-IR individually, and as a group, total, 12alpha hydroxylated, primary and secondary bile acids were also significant (FDR < 0.05). When stratifying by BMI, chenodeoxycholic acid (CDCA), cholic acid (CA), UDCA, 5beta-cholanic acid-3beta, deoxycholic acid, and total, 12alpha hydroxylated, primary and secondary bile acid groups were significantly positively associated with HOMA-IR among overweight to obese individuals (FDR < 0.05). When stratifying by sex, GCA, CDCA, TCA, CA, UDCA, GDCA, glycolithocholic acid (GLCA), total, primary, 12alpha-hydroxylated, and glycine-conjugated bile acids were significantly associated with HOMA-IR among women, and CDCA, GDCA, and GLCA were significantly associated among men (FDR < 0.05). There were no significant associations between bile acids and CRP. CONCLUSIONS: Diets with comparable macronutrient and energy composition, but differing in carbohydrate source, affected fasting plasma bile acids differently. Specifically, a diet characterized by whole grains, legumes, and fruits and vegetables compared to a diet high in refined grains and added sugars led to modest increases in concentrations of TLCA, TCA and GCA, ligands for FXR and TGR5, which may have beneficial effects on glucose homeostasis. PMID- 29458054 TI - Comparative investigation of binding interactions with three steroidal derivatives of d(GGGT)4 G-quadruplex aptamer. AB - Steroidal derivatives have attracted tremendous attentions in biological and biomedical areas, due to their variety biological activities. The investigation of structural influences helps in understanding their biological activities. The interactions of steroidal derivatives with DNA may play important roles in biological activities, however only a few investigations were reported on this issue. Herein, the structural influences of three steroidal derivatives were investigated based on their binding interactions with d(GGGT)4 G-quadruplex aptamer by spectroscopic approaches, nuclear magnetic resonance (NMR), electrochemical methods, and molecular modeling techniques. Three compounds were found to selectively bind with parallel G-quadruplex aptamer to form three complexes through end-stacking binding modes. Three compounds stabilized the G quadruplex structure of the aptamer at different levels, which enhanced the biological activity of this aptamer to some extent. The space steric hindrance was responsible for differences in the binding interactions between d(GGGT)4 G quadruplex aptamer and three compounds. These results provide new information for the molecular understanding of binding interactions of steroidal derivatives with DNA and the strategy for research of structural influences. PMID- 29458055 TI - Brain activation associated to olfactory conditioned same-sex partner preference in male rats. AB - Sexual preferences can be strongly modified by Pavlovian learning. For instance, olfactory conditioned same-sex partner preference can occur when a sexually naive male cohabits with an scented male during repeated periods under the effects of enhanced D2-type activity. Preference is observed days later via social and sexual behaviors. Herein we explored brain activity related to learned same-sex preference (Fos-Immunoreactivity, IR) following exposure to a conditioned odor paired with same-sex preference. During conditioning trials males received either saline or the D2-type receptor agonist quinpirole (QNP) and cohabitated during 24 h with a stimulus male that bore almond scent on the back as conditioned stimulus. This was repeated every 4 days, for a total of three trials. In a drug free final test we assessed socio/sexual partner preference between the scented male and a receptive female. The results indicated that QNP-conditioned males developed a same-sex preference observed via contact, time spent, olfactory investigations, and non-contact erections. By contrast, saline-conditioned and intact (non-exposed to conditioning) males expressed an unconditioned preference for the female. Four days later the males were exposed to almond scent and their brains were processed for Fos-IR. Results indicated that the QNP-conditioned group expressed more Fos-IR in the nucleus accumbens (AcbSh), medial preoptic area (MPA), piriform cortex (Pir) and ventromedial nucleus of the hypothalamus (VMH) as compared to saline-conditioned. Intact males expressed the lowest Fos-IR in AcbSh and VMH, but the highest in MPA and Pir. We discuss the role of these areas in the learning process of same-sex partner preferences and olfactory discrimination. PMID- 29458057 TI - Roles of the insulin signaling pathway in insect development and organ growth. AB - Organismal development is a complex process as it requires coordination of many aspects to grow into fit individuals, such as the control of body size and organ growth. Therefore, the mechanisms of precise control of growth are essential for ensuring the growth of organisms at a correct body size and proper organ proportions during development. The control of the growth rate and the duration of growth (or the cessation of growth) are required in size control. The insulin signaling pathway and the elements involved are essential in the control of growth. On the other hand, the ecdysteroid molting hormone determines the duration of growth. The secretion of these hormones is controlled by environmental factors such as nutrition. Moreover, the target of rapamycin (TOR) pathway is considered as a nutrient sensing pathway. Important cross-talks have been shown to exist among these pathways. In this review, we outline the control of body and organ growth by the insulin/TOR signaling pathway, and also the interaction between nutrition via insulin/TOR signaling and ecdysteroids at the coordination of organismal development and organ growth in insects, mainly focusing on the well-studied fruit fly Drosophila melanogaster. PMID- 29458056 TI - Alcohol and CV Health: Jekyll and Hyde J-Curves. AB - A routine of light or moderate alcohol consumption (<=1 drink/day for women and 1 to 2 drinks/day for men) is associated with a lower risk for all-cause mortality, coronary artery disease (CAD), type 2 diabetes mellitus (T2D), heart failure (HF), and stroke. Conversely, heavy drinking, (>4 drinks/day) is associated with an increased risk for death and cardiovascular (CV) disease (CVD). Excessive alcohol intake trails behind only smoking and obesity among the 3 leading causes of premature deaths in the United States (US). Heavy alcohol use is a common cause of reversible hypertension (HTN), nonischemic dilated cardiomyopathy, atrial fibrillation (AF), and stroke (both ischemic and hemorrhagic). Among males aged 15 to 59 years, alcohol abuse is perhaps the leading cause of premature death. As such, the risk-to-benefit ratio of drinking is less favorable in younger individuals. A daily habit of light to moderate drinking is ideal for those who choose to consume alcohol regularly. Red wine in particular before or during the evening meal is linked with the best long-term CV outcomes. Most of the studies on alcohol and health are observational, and correlation does not prove causation. Health care professionals should not advise nondrinkers to begin drinking because of the paucity of randomized outcome data coupled with the potential for alcohol abuse even among seemingly low risk individuals. PMID- 29458058 TI - Lithium modulates the muscarinic facilitation of synaptic plasticity and theta gamma coupling in the hippocampal-prefrontal pathway. AB - Mood disorders are associated to functional unbalance in mesolimbic and frontal cortical circuits. As a commonly used mood stabilizer, lithium acts through multiple biochemical pathways, including those activated by muscarinic cholinergic receptors crucial for hippocampal-prefrontal communication. Therefore, here we investigated the effects of lithium on prefrontal cortex responses under cholinergic drive. Lithium-treated rats were anesthetized with urethane and implanted with a ventricular cannula for muscarinic activation, a recording electrode in the medial prefrontal cortex (mPFC), and a stimulating electrode in the intermediate hippocampal CA1. Either of two forms of synaptic plasticity, long-term potentiation (LTP) or depression (LTD), were induced during pilocarpine effects, which were monitored in real time through local field potentials. We found that lithium attenuates the muscarinic potentiation of cortical LTP (<20 min) but enhances the muscarinic potentiation of LTD maintenance (>80 min). Moreover, lithium treatment promoted significant cross frequency coupling between CA1 theta (3-5 Hz) and mPFC low-gamma (30-55 Hz) oscillations. Interestingly, lithium by itself did not affect any of these measures. Thus, lithium pretreatment and muscarinic activation synergistically modulate the hippocampal-prefrontal connectivity. Because these alterations varied with time, oscillatory parameters, and type of synaptic plasticity, our study suggests that lithium influences prefrontal-related circuits through intricate dynamics, informing future experiments on mood disorders.

AB - Axons within the peripheral nervous system are capable of regeneration, but full functional recovery is rare. Recent work has shown that conditional deletion of two key signaling inhibitors of the PI3K and Jak/Stat pathways-phosphatase and tensin homolog (PTEN) and suppressor of cytokine signaling-3 (SOCS3), respectively-promotes regeneration of normally non-regenerative central nervous system axons. Moreover, in studies of optic nerve regeneration, co-deletion of both PTEN and SOCS3 has an even greater effect. Here, we test the hypotheses (1) that PTEN deletion enhances axon regeneration following sciatic nerve crush and (2) that PTEN/SOCS3 co-deletion further promotes regeneration. PTENfl/fl and PTEN/SOCS3fl/fl mice received direct injections of AAV-Cre into the fourth and fifth lumbar dorsal root ganglia (DRG) two weeks prior to sciatic nerve crush. Western blot analysis of whole cell lysates from DRG using phospho-specific antibodies revealed that PTEN deletion did not enhance or prolong PI3K signaling following sciatic nerve crush. However, PTEN/SOCS3 co-deletion activated PI3K for at least 7 days post-injury in contrast to controls, where activation peaked at 3 days. Quantification of SCG10-expressing regenerating sensory axons in the sciatic nerve after crush injury revealed longer distance regeneration at 3 days post-injury with both PTEN and PTEN/SOCS3 co-deletion. Additionally, analysis of noxious thermosensation and mechanosensation with PTEN/SOCS3 co-deletion revealed enhanced sensation at 14 and 21 days after crush, respectively, after which all treatment groups reached the same functional plateau. These findings indicate that co-deletion of PTEN and SOCS3 results in modest but measureable enhancement of early regeneration of DRG axons following crush injury. PMID- 29458060 TI - Crim1 is required for maintenance of the ocular lens epithelium. AB - The development and growth of the vertebrate ocular lens is dependent on the regulated proliferation of an anterior monolayer of epithelial cells, and their subsequent differentiation into elongate fiber cells. The growth factor rich ocular media that bathes the lens mediates these cellular processes, and their respective intracellular signaling pathways are in turn regulated to ensure that the proper lens architecture is maintained. Recent studies have proposed that Cysteine Rich Motor Neuron 1 (Crim1), a transmembrane protein involved in organogenesis of many tissues, might influence cell adhesion, polarity and proliferation in the lens by regulating integrin-signaling. Here, we characterise the lens and eyes of the Crim1KST264 mutant mice, and show that the loss of Crim1 function in the ocular tissues results in inappropriate differentiation of the lens epithelium into fiber cells. Furthermore, restoration of Crim1 levels in just the lens tissue of Crim1KST264 mice is sufficient to ameliorate most of the dysgenesis observed in the mutant animals. Based on our findings, we propose that tight regulation of Crim1 activity is required for maintenance of the lens epithelium, and its depletion leads to ectopic differentiation into fiber cells, dramatically altering lens structure and ultimately leading to microphthalmia and aphakia. PMID- 29458061 TI - Decreased MCP-1/CCR2 axis-mediated chemotactic effect of conjunctival fibroblasts after transdifferentiation into myofibroblasts. AB - The purpose of this study is to investigate the change in chemotactic effects of human conjunctival fibroblasts (HConFs) after transdifferentiation into myofibroblasts, and to explore related molecular mechanisms. HConFs were treated with 5 ng/mL transforming growth factor (TGF)-beta2 for 48 h to induce transdifferentiation into myofibroblasts. The cytokine concentrations in the conditioned media of HConFs were measured by multiplex bead-based immunoassays. The Boyden chamber assay was used to assess the chemotactic effects using the monocyte cell line, THP-1 cells. The concentration of monocyte chemoattractant protein (MCP)-1 in the conditioned media was decreased after transdifferentiation into myofibroblasts (P < 0.001). The conditioned media of HConFs exerted a chemotactic effect on THP-1 cells, but this effect decreased after transdifferentiation into myofibroblasts (P = 0.032). The number of migrated THP 1 cells decreased significantly upon treatment with neutralizing anti-MCP-1 antibodies (P = 0.006) and tended to decrease upon treatment with C-C chemokine receptor (CCR) 2 antagonist. The chemotactic effect of HConFs mediated by the MCP 1/CCR2 axis was decreased after transdifferentiation into myofibroblasts.

AB - Degradation of an active pharmaceutical ingredient (API), a 2-(3-(1-(4 chlorophenyl)cyclopropyl)-[1,2,4]triazolo[4,3-a]pyridin-8-yl)propan-2-ol hydrochloride salt, was observed in a capsule formulation stressed at 50 degrees C or 40 degrees C/75% relative humidity conditions for 1 month. Two unknown degradants were identified as cationic pseudodimers of the API via accurate mass liquid chromatography-mass spectrometry and 1- and 2-dimensional NMR analyses. A plausible degradation pathway of the API was postulated which led to the identification of 2 key N-oxide degradants in the stressed capsule formulation at trace levels. It was hypothesized that the N-oxide degradants could be protonated and undergo further transformation so as to react with another API free base to form pseudodimeric N-oxide intermediates, followed by protonation/dehydration to yield the cationic pseudodimers of the API. The proposed degradation pathway was further supported by formulation screening studies: (1) the removal of magnesium stearate (base/lubricant) from the formulation to reduce the formation of API free base, which is susceptible to oxidation to form N-oxides; (2) the replacement of API hydrochloride salt by its free base form to eliminate the proton source for protonation of the N-oxides so as to prevent their further transformation; and (3) the addition of anti-oxidants to minimize the oxidation of API free base to N-oxides.

PMID- 29458065 TI - Nosocomial ventriculitis caused by a meticillin- and linezolid-resistant clone of Staphylococcus epidermidis in neurosurgical patients. AB - BACKGROUND: Postneurosurgical ventriculitis is mainly caused by coagulase negative staphylococci. The rate of linezolid-resistant Staphylococcus epidermidis (LRSE) is increasing worldwide. AIMS: To report clinical, epidemiological and microbiological data from a series of ventriculitis cases caused by LRSE in a Spanish hospital between 2013 and 2016. METHODS: Cases of LRSE ventriculitis were reviewed retrospectively in a Spanish hospital over a four-year period. Clinical/epidemiological data of the infected patients were reviewed, the isolates involved were typed by pulsed-field gel electrophoresis (PFGE) and multi-locus sequence typing, and the molecular bases of linezolid resistance were determined. FINDINGS: Five cases of LRSE ventriculitis were detected. The patients suffered from cerebral haemorrhage or head trauma that required the placement of an external ventricular drain; spent a relatively long time in the intensive care unit (ICU) (10-26 days); and three out of the five patients had previously been treated with linezolid. All LRSE had the same PFGE pattern, belonged to ST2, and shared an identical mechanism of linezolid resistance. Specifically, all had the G2576T mutation in the V domain of each of the six copies of the 23S rRNA gene, together with the Q136L and M156T mutations and the 71GGR72 insertion in the L3 and L4 ribosomal proteins, respectively. CONCLUSION: The high ratio of linezolid consumption in the ICU (7.72-8.10 defined daily dose/100 patient-days) could have selected this resistant clone, which has probably become endemic in the ICU where it could have colonized admitted patients. Infection control and antimicrobial stewardship interventions are essential to prevent the dissemination of this difficult-to-treat pathogen, and to preserve the therapeutic efficacy of linezolid. PMID- 29458066 TI - Volitional Voiding of the Bladder after Spinal Cord Injury: Validation of Bilateral Lower Extremity Motor Function as a Key Predictor. AB - PURPOSE: In many individuals with spinal cord injury a return of volitional bladder voiding is considered more important than regaining motor function. Recently a predictive model using only composite bilateral lower extremity motor scores for levels L2-S1 (range 0 to 50) was proposed by the EMSCI (European Multicenter Study about Spinal Cord Injury) group. The model showed exceptional predictive power with an AUC of 0.912. We sought to further validate the EMSCI model in a national spinal cord injury cohort. MATERIALS AND METHODS: We created models of volitional voiding using the United States NSCID (National Spinal Cord Injury Database) for 2007 to 2016. In addition to testing lower extremity motor scores, we evaluated other patient variables that we hypothesized might affect volitional voiding. RESULTS: Volitional voiding was present in 1,333 of the cohort of 4,327 individuals (30.8%) at 1-year followup. While younger age, female gender, increased sacral sparing, improved AIS (American Spinal Injury Association Impairment Scale) classification and a more caudal sensory level predicted volitional voiding, lower extremity motor scores were most predictive (AUC 0.919). Adding the other patient characteristics did little to improve model performance (full model AUC 0.932). Further analysis of the predictive power of lower extremity motor scores suggested that while the AUC appeared to decrease in persons who were most likely to void volitionally, the performance of the predictive model remained outstanding with a combined AIS C and D AUC of 0.792. CONCLUSIONS: Our study verifies the validity of the EMSCI predictive model of volitional voiding after spinal cord injury. The differing performance of lower extremity motor scores in various AIS classifications should be noted. PMID- 29458067 TI - Fluctuations of extracellular glucose and lactate in the mouse primary visual cortex during visual stimulation. AB - We measured the extracellular glucose and lactate in the primary visual cortex in the CD-1 mouse using electrochemical electrodes. To gain some additional information on brain metabolism, we examined the impact of systemic injections of lactate and fructose on the brain extracellular glucose and lactate changes observed during visual stimulation. We found that simple stimulation using a flashlight produced a decrease in visual cortex extracellular glucose and an increase in extracellular lactate. Similar results were observed following visual stimulation with an animated movie without soundtrack or the presentation of a novel object. Specificity of these observations was confirmed by the absence of extracellular glucose and lactate changes when the mice were presented a second time with the same object. Previous experiments have shown that systemic injections of fructose and lactate lead to an increase in blood lactate but no change in blood glucose while they both increase brain extracellular glucose but they do not increase brain extracellular lactate. When mice were visually stimulated after they had received these injections, we found that lactate, and to a slightly lesser degree fructose, both reduced the amplitude of the changes in extracellular glucose and lactate that accompanied visual stimulation. Thus, neural activation leads to an increase in extracellular lactate and a decrease in extracellular glucose. Novelty, attentional resources and availability of metabolic fuels modulate these fluctuations. The observations are consistent with a modified view of brain metabolism that takes into account the blood and brain glucose availability. PMID- 29458068 TI - Ovarian microcystic stromal tumor with undetermined potential: case study with molecular analysis and literature review. AB - Ovarian microcystic stromal tumor is a relatively rare tumor type. This tumor is characterized by a unique microcyst structure, and essentially all tumors show benign biological behavior. Here, we report a case with a primary ovarian microcystic stromal tumor that experienced recurrence. Pathological findings showed that the original tumor, relapsed tumor in the ovary, and the recurrent tumor in the iliac fossa presented similar histologic features. The tumor mainly consisted of microcysts, solid cellular regions, and a fibrous stroma. Immunohistochemically, the tumor cells were positive for beta-catenin, CD10, vimentin, and WT-1. Mutational analysis revealed a missense mutation (c.1590C>T; pG530E) in exon 15 of the APC gene and another missense mutation (c.740G>A; pA247V) in exon 1 of the KRAS gene. We also reviewed other published cases to evaluate the prognosis and treatment. This is the first report to describe a microcystic stromal tumor of the ovary presenting with undetermined biological potential. PMID- 29458069 TI - High expression of NPRL2 is linked to poor prognosis in patients with prostate cancer. AB - As a tumor suppressor candidate gene, NPRL2 has anticancer effects against several cancers, but its potential role in prostate cancer (PCa) has not been reported. The present study aimed to explore the expression of NPRL2 in PCa and its potential clinical significance. Our results showed that expression of NPRL2 in PCa tissues was significantly higher than that in non-PCa tissues (P < .001). High NPRL2 expression in PCa tissue was significantly correlated with a high Gleason grade group (P < .001), high pT stage (P < .001), and lymph node metastasis (P = .003). The overall survival of PCa patients with negative to weak NPRL2 expression was significantly higher than that of patients with moderate to strong positive NPRL2 expression. Furthermore, in vitro, we found that the up regulated NPRL2 level in LNCaP and PC3 cells, and forced reexpression of NPRL2 significant promoted the growth of those cells and vice versa. Contrary to existing reports, our results interestingly showed, for the first time, that the expression level of NPRL2 was significantly up-regulated in PCa and its high expression was correlated with poor prognosis, suggesting its pivotal role in the progression of PCa. NPRL2 may serve as a potential prognostic biomarker for PCa patients. PMID- 29458070 TI - The epigenetic alterations of endogenous retroelements in aging. AB - Endogenous retroelements, transposons that mobilize through RNA intermediates, include some of the most abundant repetitive sequences of the human genome, such as Alu and LINE-1 sequences, and human endogenous retroviruses. Recent discoveries demonstrate that these mobile genetic elements not only act as intragenomic parasites, but also exert regulatory roles in living cells. The risk of genomic instability represented by endogenous retroelements is normally counteracted by a series of epigenetic control mechanisms which include, among the most important, CpG DNA methylation. Indeed, most of the genomic CpG sites subjected to DNA methylation in the nuclear DNA are carried by these repetitive elements. As other parts of the genome, endogenous retroelements and other transposable elements are subjected to deep epigenetic alterations during aging, repeatedly observed in the context of organismal and cellular senescence, in human and other species. This review summarizes the current status of knowledge about the epigenetic alterations occurring in this large, non-genic portion of the genome in aging and age-related conditions, with a focus on the causes and the possible functional consequences of these alterations. PMID- 29458071 TI - B cells in operational tolerance. AB - Transplantation is currently the therapy of choice for endstage organ failure even though it requires long-term immunosuppresive therapy, with its numerous side effects, for acceptance of the transplanted organ. In rare cases however, patients develop operational tolerance, that is, graft survival without immunosuppression. Studies conducted on these patients reveal genetic, phenotypic, and functional signatures. They provide a better understanding of the immunological mechanisms involved in operational tolerance and define biomarkers that could be used to adapt immunosuppressive treatment to the individual, safely reduce immunosuppression doses, and ideally and safely guide immunosuppression withdrawal. This review summarizes studies that suggest a role for B cells as biomarkers of operational tolerance and discusses the use of B cells as a predictive tool for immunologic risk. PMID- 29458072 TI - Influence of Xenorhabdus (Gamma-Proteobacteria: Enterobacteriaceae) symbionts on gonad postembryonic development in Steinernema (Nematoda: Steinernematidae) nematodes. AB - Steinernema nematodes and their Xenorhabdus partners form an obligate mutualistic association. This partnership is insecticidal to a wide range of insects. Steinernema rely on their Xenorhabdus partner to produce toxins inside the insect cadaver to liberate nutrients from the insect, as well as antimicrobials to sterilize the cadaver, thus creating a suitable environment for reproduction. In return, Steinernema vector their Xenorhabdus between insect hosts. Disruption of this partnership may affect the success of both partners. For instance, when Steinernema associates with non-cognate symbionts, their virulence and reproductive fitness are affected. In this study, we examined the effect of symbiotic (cognate and non-cognate) and non-symbiotic bacteria on maturation time, gonad postembryonic development, and sex ratio of first-generation Steinernema adults. Two Steinernema spp. were considered: S. feltiae SN and S. carpocapsae All. In vitro assays were carried out by pairing each nematode sp. with symbiotic (cognate and non-cognate) Xenorhabdus, and with non-symbiotic bacteria (Serratia proteamaculans). Additionally, for comparative purposes, we also considered adult nematodes reared in vivo in Galleria mellonella larvae to assess nematode development under natural conditions. Results from this study showed non-symbiotic Serratia proteamaculans did not support adult development of S. feltiae but it allowed development of S. carpocapsae adults. Sex ratio decreased from 2:1 to 1:1 (female: male) when S. carpocapsae adults were reared with the non-symbiotic S. proteamaculans. Cognate or non-cognate Xenorhabdus spp. and/or strains did not change the sex ratio of any of either Steinernema spp. tested. Morphometric analysis also revealed that bacterial conditions influenced adult size and gonad postembryonic development in both Steinernema species. Body size (length and width), and gonad length in both S. feltiae males and females, were significantly reduced when reared with a non-cognate Xenorhabdus species. In S. carpocapsae, males exhibited an enhanced body size (length and width) and gonad length when reared with a non-cognate X. nematophila strain. S. carpocapsae females also exhibited an enhanced gonad length when reared with a non-cognate X. nematophila strain. S. carpocapsae males and females were underdeveloped when reared with the non-symbiotic S. proteamaculans, and exhibited reduced body sizes and gonad lengths. We conclude that development of first-generation adults of both Steinernema spp. tested, in particular time to adult maturation as well as body and gonad size were directly influenced by the bacterial symbionts they were cultured with. However, response to the culture conditions was species specific. PMID- 29458073 TI - Establishment and validation of a prediction model for ischemic stroke risks in patients with type 2 diabetes. AB - AIMS: A risk scoring system for predicting ischemic stroke incidence may identify type 2 diabetes patients at high risk for ischemic stroke who can benefit from preventive intervention programs. Such a risk scoring system can serve as a benchmark to test novel putative risk factors. METHODS: The study adopted a retrospective cohort, including 28,124 Chinese patients with type 2 diabetes aged 30-84 years during 2001-2004. Participants were randomly assigned to the derivation and validation sets at a 2:1 ratio. Cox's proportional hazard regression model was used to identify risk factors of ischemic stroke incidence in the derivation set. And then the steps proposed by the Framingham Heart Study for establishing an ischemic stroke prediction model with a scoring system was used. RESULTS: Among 9374 patients in the validation set, 1076 subjects (11.48%) developed ischemic stroke with a mean follow up period of 8.0 years. We identified the following risk factors: age, gender, smoking habit, duration of type 2 diabetes, blood pressure, HbA1c level, total cholesterol to high-density lipoprotein ratio, creatinine, fasting plasma glucose variation (FPG-CV), arterial embolism and thrombosis, diabetes retinopathy, hypoglycemia, anti diabetes medication use, and cardiovascular medication. The area under receiver operating characteristic curve of the 3-year, 5-year, and 8-year ischemic stroke incidence risks were 0.72, 0.71, and 0.68 for the validation set, respectively. CONCLUSIONS: This proposed ischemic stroke incidence risk prediction model is the first model established for Chinese patients with type 2 diabetes recruited from nationwide clinical settings. PMID- 29458074 TI - Subthalamic nucleus stimulation, dopaminergic treatment and impulsivity in Parkinson's disease. AB - BACKGROUND: Deep brain stimulation of the subthalamic nucleus (STN DBS) is known to increase response speed and lower response accuracy in Parkinson's disease (PD) patients. It has been proposed that this speed-accuracy tradeoff is due to enhanced sensitivity of the motor system to sensory information. An alternative possibility is that this effect is due to weakened suppressive processes. The two alternative interpretations can be tested by analyzing the electromyographic activity (EMG) of the response agonists when the patients perform conflict reaction time tasks. In those tasks, fast subthreshold muscle impulses often occur in the agonist of the incorrect response. These impulses are partial errors that are suppressed before being behaviourally committed. MATERIAL AND METHODS: Here we analyzed the EMG of the response agonists recorded while sixteen PD patients performed a Simon task that elicits prepotent response tendencies so as to decipher (i) whether STN DBS affects the expression and/or suppression of subthreshold muscle impulses that are critical for action control and (ii) the interaction between dopaminergic treatment and STN DBS. The patients were tested On and Off STN DBS and On and Off dopaminergic medication in a full factorial design. RESULTS: STN DBS not only impaired the proficiency to suppress subliminal action impulses (p = 0.01) but also favoured the muscular expression of fast incorrect impulses (p < 0.001). Dopaminergic treatment only affected the action impulses suppression (p = 0.02) and did not change the effect of STN DBS on impulsive action control. CONCLUSION: Contrary to a recent proposal, STN DBS impaired rather than improved action control by weakening erroneous impulse suppression, whether the patients were On or Off their usual medication. These findings are discussed in light of a recent proposal (Servant M, White C, Montagnini A, Burle B, 2015) that reconciles partial errors with accumulation-to bound models of decision making. Our results suggest that medication specifically lowers the mechanical threshold while STN DBS lowers the mechanical threshold and to a lesser extent the EMG-threshold. PMID- 29458075 TI - Lateral inhibition in the autism spectrum: An SSVEP study of visual cortical lateral interactions. AB - Circuit level brain dysfunction has been suggested as a common mechanism through which diverse genetic risk factors and neurobiological sequelae lead to the core features of autism spectrum disorder (Geschwind 2009; Port et al. 2014). An important mediator of circuit level brain activity is lateral inhibition, and a number of authors have suggested that lateral inhibition may be atypical in ASD. However, evidence regarding putative atypical lateral connections in ASD is mixed. Here we employed a steady state visual evoked potential (SSVEP) paradigm to further investigate lateral connections within a group of high functioning adults with ASD. At a group level, we found no evidence of altered lateral interactions in ASD. Exploratory analyses reveal that greater ASD symptom severity (increased ADOS score) is associated with increased short range lateral inhibition. These results suggest that lateral interactions are not altered in ASD at a group-level, but that subtle alterations in such neurobiological processes may underlie the heterogeneity seen in the autism spectrum in terms of sensory perception and behavioral phenotype. PMID- 29458076 TI - Bone marrow mesenchymal stem cells (BMSCs) improved functional recovery of spinal cord injury partly by promoting axonal regeneration. AB - Spinal cord injury (SCI) disrupts the spinal cord and results in the loss of sensory and motor function below the lesion site. The treatment of SCI became a challenge because the injured neurons fail to axon regenerate and repair after injury. Promoting axonal regeneration plays a key role in the treatment strategies for SCI. It would meet the goal of reconstruction the injured spinal cord and improving the functional recovery. Bone marrow mesenchymal stem cells (BMSCs) are attractive therapeutic potential cell sources for SCI, and it could rebuild the injured spinal cord through neuroprotection, neural regeneration and remyelinating. Evidence has demonstrated that BMSCs play important roles in mediating axon regeneration, and glial scar formation after SCI in animal experiments and some clinical trials. We reviewed the role of BMSCs in regulating axon regeneration and glial scar formation after SCI. BMSCs based therapies may provide a therapeutic potential for the injured spinal cord by promoting axonal regeneration and repair. PMID- 29458077 TI - Reciprocal regulation of the Cadherin-11/Stat3 axis by caveolin-1 in mouse fibroblasts and lung carcinoma cells. AB - Caveolin-1 (Cav1) is an integral plasma membrane protein and a complex regulator of signal transduction. The Signal Transducer and Activator of Transcription-3 (Stat3) is activated by a number of receptor and non-receptor tyrosine kinases and is positively implicated in cancer. Despite extensive efforts, the relationship between Cav1 and Stat3 has been a matter of controversy. We previously demonstrated that engagement of E- or N-cadherin or cadherin-11 cell to cell adhesion molecules, as occurs with confluence of cultured cells, triggers a dramatic increase in the levels of tyr705 phosphorylated i.e. activated Stat3, by a mechanism requiring the cRac1 small GTPase. Since confluence was not taken into account in previous studies, we revisited the question of the relationship between Cav1 and Stat3-ptyr705 in non-transformed mouse fibroblasts and in human lung carcinoma cells, by examining their effect at different cell densities. Our results unequivocally demonstrate that Cav1 downregulates cadherin-11, by a mechanism which requires the Cav1 scaffolding domain. This cadherin-11 downregulation, in turn, leads to a reduction in cRac1 and Stat3 activity levels. Furthermore, in a feedback loop possibly through p53 upregulation, Stat3 downregulation increases Cav1 levels. Our data reveal the presence of a potent, negative regulatory loop between Cav1 and cadherin-11/Stat3, leading to Stat3 inhibition and apoptosis. PMID- 29458078 TI - Isolation of intact RNA from murine CD4+ T cells after intracellular cytokine staining and fluorescence-activated cell sorting. AB - Intracellular cytokine staining (ICS) is a powerful method for identifying functionally distinct lymphocyte subsets, and for isolating these by fluorescence activated cell sorting (FACS). Although transcriptomic analysis of cells sorted on the basis of ICS has many potential applications, this is rarely performed because of the difficulty in isolating intact RNA from cells processed using standard fixation and permeabilization buffers for ICS. To address this issue, we compared three buffers shown previously to preserve RNA in nonhematopoietic cells subjected to intracellular staining for their effects on RNA isolated from T lymphocytes processed for ICS. Our results showed that buffers containing the recombinant ribonuclease inhibitor RNasin or high molar concentrations of salt yielded intact RNA from fixed and permeabilized T cells. As proof of principle, we successfully used the buffer containing RNasin to isolate intact RNA from CD4+ T cells that were sorted by FACS on the basis of specific cytokine production, thus demonstrating the potential of this approach for coupling ICS with transcriptomic analysis. PMID- 29458079 TI - Autofluorescence: A potential pitfall in immunofluorescence-based inflammation grading. AB - Immunofluorescence (IF) staining of paraffin-embedded tissues is a frequently used method to answer research questions or even detect the abundance of a certain protein for diagnostic use. However, the signal originating from specific antibody-staining might be distorted by autofluorescence (AF) of the assessed tissue. Although the AF phenomenon is well known, its presence is often neglected by insufficient staining controls. In this study, we describe the existence of cellular AF in paraffin-embedded healthy and inflamed human and murine colonic tissues and present ways to reduce AF. The AF signal is detectable at emission spectra from 425 nm-738 nm, upon excitation from 403.6-638.7 nm and appears more pronounced in inflamed tissues. Most signals are located subepithelially in the tissue and in blood vessels. Previous studies have shown that the AF signals are caused by lipofuscin, which accumulates in lamina propria immune cells. In murine small intestine AF signals are present in granules in the Paneth cell zone. For alleviation of the AF signal, sudan black b (SBB) or copper sulfate was used. Incubation of the tissue slices with either one of the substances reduced AF. In conclusion, AF appears as an intrinsic biomarker for colonic inflammation. The dominant existence of AF in immune cells of IBD tissue elucidates the importance of negative controls and the limitation of IF staining for potential diagnostic purposes. PMID- 29458081 TI - Di (2-ethylhexyl) phthalate (DEHP) alters proliferation and uterine gland numbers in the uteri of adult exposed mice. AB - Di-(2-ethylhexyl) phthalate (DEHP) is an endocrine-disrupting chemical that has been shown to impair normal reproductive function in males and females. This study investigated whether adult exposure to environmental and occupational doses of DEHP alters homeostasis of uterine proliferation, morphology, and number of uterine glands. Adult female CD1 mice were orally dosed with DEHP (0, 20 MUg/kg/day, 200 MUg/kg/day, 20 mg/kg/day or 200 mg/kg/day) for 30 days. Results indicated that DEHP at 200 MUg/kg/day caused a reduction in epithelial cell proliferation in the uterus (p < .05). We also observed an increase (p < .05) in the number of uterine glands in mice dosed with 200 mg/kg/day DEHP. Results showed that DEHP caused an increase (p < .05) in dilated blood vessels in the endometrium at 200 MUg/kg/day, 20 mg/kg/day and 200 mg/kg/day. DEHP also increased proliferation of endometrial stromal cells at 200 MUg/kg/day DEHP (p < .0010), 20 mg/kg/day DEHP (p < .0001) and 200 mg/kg/day DEHP (p < .0186). Results suggest that, exposure to specific doses of DEHP for 30 days can have adverse effects on reproductive function. PMID- 29458080 TI - Transcriptomic and phenotypic profiling in developing zebrafish exposed to thyroid hormone receptor agonists. AB - There continues to be a need to develop in vivo high-throughput screening (HTS) and computational methods to screen chemicals for interaction with the estrogen, androgen, and thyroid pathways and as complements to in vitro HTS assays. This study explored the utility of an embryonic zebrafish HTS approach to identify and classify endocrine bioactivity using phenotypically-anchored transcriptome profiling. Transcriptome analysis was conducted on zebrafish embryos exposed to 25 estrogen-, androgen-, or thyroid-active chemicals at concentrations that elicited adverse malformations or mortality at 120 h post-fertilization in 80% of animals exposed. Analysis of the top 1000 significant differentially expressed transcripts and developmental toxicity profiles across all treatments identified a unique transcriptional and phenotypic signature for thyroid hormone receptor agonists. This unique signature has the potential to be used as a tiered in vivo HTS and may aid in identifying chemicals that interact with the thyroid hormone receptor. PMID- 29458082 TI - Beyond Pain: Nurses' Assessment of Patient Suffering, Dignity, and Dying in the Intensive Care Unit. AB - CONTEXT: Deaths in the intensive care unit (ICU) are increasingly common in the U.S., yet little is known about patients' experiences at the end of life in the ICU. OBJECTIVES: The objective of this study was to determine nurse assessment of symptoms experienced, and care received by ICU patients in their final week, and their associations with nurse-perceived suffering and dignity. METHODS: From September 2015 to March 2017, nurses who cared for 200 ICU patients who died were interviewed about physical and psychosocial dimensions of patients' experiences. Medical chart abstraction was used to document baseline patient characteristics and care. RESULTS: The patient sample was 61% males, 70.2% whites, and on average 66.9 (SD 15.1) years old. Nurses reported that 40.9% of patients suffered severely and 33.1% experienced severe loss of dignity. The most common symptoms perceived to contribute to suffering and loss of dignity included trouble breathing (44.0%), edema (41.9%), and loss of control of limbs (36.1%). Most (n = 9) remained significantly (P < 0.05) associated with suffering, after adjusting for physical pain, including fever/chills, fatigue, and edema. Most patients received vasopressors and mechanical ventilation. Renal replacement therapy was significantly (<0.05) associated with severe suffering (adjusted odds ratio [AOR] 2.53) and loss of dignity (AOR 3.15). Use of feeding tube was associated with severe loss of dignity (AOR 3.12). CONCLUSION: Dying ICU patients are perceived by nurses to experience extreme indignities and suffer beyond physical pain. Attention to symptoms such as dyspnea and edema may improve the quality of death in the ICU.

PMID- 29458083 TI - Endovascular Treatment of Isolated Degenerative Superficial Femoral Artery Aneurysm. AB - Isolated degenerative superficial femoral artery (SFA) aneurysms are rare. One hundred forty-two cases are described in literature. Threshold for operative management varies in literature. In literature, only 10 cases are treated in an endovascular way. We present a case of a 77-year-old patient who presented with nonhealing wounds on the right foot. Duplex ultrasound revealed an isolated aneurysm of the SFA on the right side as a source of emboli. The patient was treated in an endovascular way with a covered stent graft. The procedure was complicated by embolization in the peroneal artery as a single outflow vessel. An overview of endovascular treatment of SFA aneurysms in literature is discussed.

AB - The precise knowledge on various interactions of metal nanoparticles (NP) in a living organism is scarce. It is expected that metals can bind to nucleic acids, peptides and proteins (e.g. enzymes), and modify the functioning of vital cellular compartments after entering the organism. The predictive factors for quantitative nanostructure-activity relationship (QNAR) analysis could enhance efficient and harmless usage of nanoparticles (NPs) in the industry as well in the medicine. The studies value the composition of the NP corona determined by time, temperature and source of protein which has been found to implicate the physiological behaviour of NPs. One has largely been ignored: the NPs specific isoelectric point (IEP) and pH at the state of measurement. Herein, this study investigates the effect of pH and surface charge of six metal oxide (MeOx) NPs on time dependency of cytotoxicity. Several aspects of the characterization of ultrafine particles in the actual test system which is the most relevant for the interpretation of the toxicological data are referred: (i) the difference of pH in the room temperature and in the incubation conditions (ii) the difference of dispersions in MilliQ and complete cell media; (iii) the need to exemplify also the pH and isoelectric point when the hydrodynamic size is measured; (iv) the importance of time due to the time-dependent equilibration and changes of NPs corona. The surface charge determines the formation of corona and could be modified by pH. MeOx NPs without fully charge equilibrated corona might play the main role of MeOx NPs entering into the cell and consequently the time dependent manifestation of the cellular effect.

AB - Traumatic brain injury (TBI) occurs when external mechanical forces induce brain damage as result of impact, penetration or rapid acceleration/deceleration that causes deformation of brain tissue. Depending on its severity, TBI can be classified as mild, moderate or severe and can lead to blood-brain barrier (BBB) dysfunction. In the present study, we evaluated the effects of uniaxial high speed stretch (HSS) at 0, 5, 10 and 15% on a pure culture of primary rat brain endothelial cells as an in vitro model of TBI to the BBB. LDH release, viability and apoptosis analysis, expression of tight junction proteins and endothelial permeability were evaluated 24 h after a single stretch episode. HSS slightly increased cell death and apoptosis at 10 and 15%, while LDH release was increased only at 15% stretch. Occludin expression was increased at 10% stretch, while claudin-5 expression was increased at 5% stretch, which also decreased the endothelial permeability. In summary, 15% HSS induced low levels of cell death, consistent with mild TBI and very low percentages of HSS (5%) enhanced the BBB properties, promoting the formation of a stronger barrier. These data support the use of 15% HSS as valuable tool in the study of mild TBI to the BBB in vitro. PMID- 29458087 TI - NGF/FAK signal pathway is implicated in angiogenesis after acute cerebral ischemia in rats. AB - Neurogenesis in the cerebral infarction after an ischemic event is important to the rehabilitation of patients. However, the mechanism of angiogenesis around cerebral ischemia is not clear. Our study designed to test whether the nerve growth factor (NGF)-P-focal adhesion kinase (FAK) signaling pathway for associations with angiogenesis plays a key role in post-acute cerebral ischemia of rats. Firstly, we implanted the Matrigel, a carrier of basement membrane matrix, into the abdominal skin of rats to identify the relevant components of the NGF-P-FAK signaling pathway related to angiogenesis. Secondly, we used a model established by ligation of the middle cerebral artery (MCA) to observe the effect of the same signal pathway on angiogenesis in the subventricular and subgranular zones of the dentate gyrus(SVG and SGZ). The results showed that the tissue scores was significantly increased by NGF. However, the tissue scores was signifcaintly decreased by FAK inhibitor TAE226. Furthermore, CD31 and alpha-SMA were significantly increased by NGF and were decreased by anti-NGF and TAE226 in Matrigel. The P-FAK protein expression in Matrigel was markedly increased by NGF and decreased by TAE226. In the SVZ and SVG of cerebral ischemia, the numbers of BrdU-positive cells were significantly increased by NGF and decreased by TAE226, respectively. Our findings suggest that the therapy targeting the NGF-P-FAK signaling pathway may be an option for patients suffering from cerebral ischemia. PMID- 29458088 TI - Antibiotics use among Palestine refugees attending UNRWA primary health care centers in Jordan - A cross-sectional study. AB - : The irrational use of antibiotics is increasing in Jordanian refugee camps and consequently so too is bacterial resistance. About one-third of health expenditures at UNRWA health centers in Jordan are attributed to antibiotics. OBJECTIVE: We studied knowledge, attitude and behaviour of Palestine refugees attending UNRWA health centers in Jordan regarding antibiotic use in order to plan public health interventions accordingly. METHODS: A cross-sectional, interviewer-administered survey among 250 adult Palestine refugees at four different health centers was conducted. RESULTS: Irrational antibiotic use was widespread: 63% of patients share antibiotics at home, 38% use left-over antibiotics and 60% purchase antibiotics directly from the pharmacy without prescription (OTC) .1 At the same time, knowledge about antibiotics side effects, resistance, and target agent was low. 90% of patients trust their doctor, however long waiting hours prevent them from seeking medical advice, which significantly increased self-medication. CONCLUSIONS: Our findings suggest a strong need for public education about antibiotics. In addition, health institutional level improvements such as shorter waiting hours and strict regulations prohibiting dispensing without prescription are necessary to combat growing bacterial resistance.

AB - Plant derived small molecules, which interact with and stabilize G-quadruplex DNA, act as inhibitors of telomere elongation and oncogene expression in humans. The inhibition of telomerase enzyme has immense potential since it is over expressed in most cancer cells. Interaction of palmatine, an antitumor alkaloid, to parallel G-quadruplex DNA, [d(TTGGGGT)]4 and [d(TTAGGGT)]4, has been investigated using Nuclear Magnetic Resonance (NMR), fluorescence and Circular Dichroism (CD) spectroscopy. Titrations were monitored by 1H and 31P NMR spectra and solution structure of palmatine-[d(TTGGGGT)]4 complex was obtained by restrained Molecular Dynamics (rMD) simulations using distance restraints from 2D NOESY spectra. Thermal stabilization of DNA was determined by CD, 1H NMR and Differential Scanning Calorimetry (DSC). Binding of palmatine induces 98% enhancement of fluorescence accompanied by blue shift ~8 nm. CD spectral bands of DNA show minor changes. Diffusion NMR studies confirm formation of a stable complex. Proton NMR signals of palmatine shift upfield upon binding and NOE cross peaks of H10, H3, H28, 5OCH3 protons with T2, A3/G3, G6 and T7 residues reveal dual recognition sites in both G-quadruplex DNA sequences, resulting in thermal stabilization of G-quadruplex by ~13-17 degrees C. Restrained molecular dynamics simulations using NOE distance restraints for 2:1 palmatine-[d(TTGGGGT)]4 complex reveal end-stacking of palmatine at G6pT7 step and groove binding along T2pG3 step. Binding to [d(TTAGGGT)]4 takes place at T2pA3pG4 and G6pT7 steps. Structural features of molecular recognition of two different G-quadruplex DNA sequences by palmatine have relevance in rational drug development for anti cancer therapy. PMID- 29458090 TI - Designing fluorescent biosensors using circular permutations of riboswitches. AB - RNA-based fluorescent (RBF) biosensors have been applied to detect a variety of metabolites in vitro and in live cells. They are designed by combining the ligand sensing domain of natural riboswitches with in vitro selected fluorogenic aptamers. Different biosensor topologies have been developed to accommodate the diversity of riboswitch structures. Here we show that circular permutation of the riboswitch ligand sensing domain also gives functional biosensors, using the SAM I riboswitch as our model. We reveal that this design can enhance fluorescence turn-on and ligand binding affinity compared to the non-permuted topology. PMID- 29458092 TI - Ramifications of the Children's Surgery Verification Program for Patients and Hospitals. AB - BACKGROUND: The American College of Surgeons in 2015 instituted the Children's Surgery Verification program delineating requirements for hospitals providing pediatric surgical care. Our purpose was to examine possible effects of the Children's Surgery Verification program by evaluating neonates undergoing high risk operations. STUDY DESIGN: Using the Kid's Inpatient Database 2009, we identified infants undergoing operations for 5 high-risk neonatal conditions. We considered all children's hospitals and children's units Level I centers and considered all others Level II/III. We estimated the number of neonates requiring relocation and the additional distance traveled. We used propensity score adjusted logistic regression to model mortality at Level I vs Level II/III hospitals. RESULTS: Overall, 7,938 neonates were identified across 21 states at 91 Level I and 459 Level II/III hospitals. Based on our classifications, 2,744 (34.6%) patients would need to relocate to Level I centers. The median additional distance traveled was 6.6 miles. The maximum distance traveled varied by state, from <55 miles (New Jersey and Rhode Island) to >200 miles (Montana, Oregon, Colorado, and California). The adjusted odds of mortality at Level II/III vs Level I centers was 1.67 (95% CI 1.44 to 1.93). We estimate 1 life would be saved for every 32 neonates moved. CONCLUSIONS: Although this conservative estimate demonstrates that more than one-third of complex surgical neonates in 2009 would have needed to relocate under the Children's Surgery Verification program, the additional distance traveled is relatively short for most but not all, and this program might improve mortality. Local level ramifications of this novel national program require additional investigation. PMID- 29458091 TI - Role of the sseK1 gene in the pathogenicity of Salmonella enterica serovar enteritidis in vitro and in vivo. AB - Salmonella enteritidis is a common food-borne pathogen associated with consumption of contaminated poultry meat and eggs, which frequently causes gastroenteritis in humans. Salmonella secreted effector K1 (SseK1), as a translocated and secreted protein has been identified to be essential for the virulence of Salmonella typhimurium in host cells. However, the role of the sseK1 gene in the pathogenicity of S. enteritidis remain unclear. In this study, a sseK1 deletion mutant of S. enteritidis was constructed and its biological characteristics were examined. It was found that the sseK1 deletion mutant did not affect the growth, adherence and invasion of Salmonella enteritidis when compared to the wild-type S. enteritidis. However, the mutant showed decreased formation of biofilm and significantly reduced intracellular survival of bacteria in activated mouse peritoneal macrophages, as well as showed reduced pathogenicity to a murine model by increasing the lethal dose 50% (LD50) value and decreasing the proliferation ratio of bacteria in vivo. Taken together, this study determined an important role for SseK1 in the pathogenicity of S. enteritidis in vitro and in vivo. PMID- 29458093 TI - Protective efficacy of Mucuna pruriens (L.) seed meal enriched diet on growth performance, innate immunity, and disease resistance in Oreochromis mossambicus against Aeromonas hydrophila. AB - The impact of Mucuna pruriens (L.) seed meal diet on growth performance, innate immune response, and disease resistance in Oreochromis mossambicus against Aeromonas hydrophila is reported for the first time. Infected O. mossambicus was fed with 2 g kg-1, 4 g kg-1, and 6 g kg-1 of M. pruriens seed meal diets significantly increased initial body weight (IBW) and final body weight (FBW) over control, for a period of 4 weeks. At 4 g kg-1 and 6 g kg-1 the enriched diet significantly (P < 0.05) enhanced the survival rate, weight gain (WG), protein efficiency ratio (PER), specific growth rate (SGR), feed conversion ratio (FCR), and feed efficiency (FE) when compared to the control; besides, from weeks 2-4 these diets significantly (P < 0.05) enhanced the complement activity, phagocytic activity, respiratory burst activity, and lysosome activity. On being fed with 4 g kg-1 and 6 g kg-1-enriched diets the cumulative mortality was lower (10% and 12%) than with 2 g kg-1 diet (24%). The present investigation suggests that the enriched diet at 4 g kg-1 and 6 g kg-1 improved the growth performance more than that of the control and negative control; it also positively enhanced the innate immunity and disease resistance against A. hydrophilla in O. mossambicus. Hence M. pruriens can be used as a feed additive to stimulate immunity for effective production of economically valuable freshwater fish, O. mossambicus. PMID- 29458094 TI - A conserved interferon regulation factor 1 (IRF-1) from Pacific oyster Crassostrea gigas functioned as an activator of IFN pathway. AB - Interferon regulatory factors (IRFs), a family of transcription factors with a novel helix-turn-helix DNA-binding motif, play important roles in regulating the expression of interferons (IFNs) and IFN-stimulated genes. In the present study, an interferon regulation factor 1 was identified from oyster Crassostrea gigas (designated CgIRF-1), and its immune function was characterized to understand the regulatory mechanism of interferon system against viral infection in invertebrates. The open reading frame (ORF) of CgIRF-1 was 990 bp, encoding a polypeptide of 329 amino acids with a typical IRF domain (also known as DNA binding domain). The mRNA transcripts of CgIRF-1 were detected in all the tested tissues with the highest expression level in hemocyte. CgIRF-1 protein was distributed in both nucleus and cytoplasm of the oyster hemocyte. The mRNA expression of CgIRF-1 in hemocytes was significantly up-regulated at 48 h after poly (I:C) stimulation (p < 0.05). The recombinant CgIRF-1 (rCgIRF-1) could interact with classically IFN-stimulated response elements (ISRE) in vitro. The relative luciferase activity of interferon-like protein promotor reporter gene (pGL-CgIFNLP promotor) was significantly (p < 0.05) enhanced in HEK293T cell after transfection of CgIRF-1. These results indicated that CgIRF-1 could bind ISRE and regulate the expression of CgIFNLP as a transcriptional regulatory factor, and participated in the antiviral immune response of oysters. PMID- 29458095 TI - Rapid, Loop-Mediated Isothermal Amplification Detection of Celiac Disease Risk Alleles. AB - Human leukocyte antigen (HLA) genotyping has become a useful investigation in the diagnostic work-up of celiac disease (CD), with utility in risk stratification and screening. However, broad application of this technology has been hindered by the cost and time burden of conventional laboratory-based assays. We have developed and validated CD-loop-mediated isothermal amplification (CD-LAMP), a LAMP assay, which enables rapid identification of the signature CD risk genotypes, HLA-DQ2.5, HLA-DQ8, HLA-DQ2.2, and HLA-DQA1*05. Sample-to-answer is achieved in approximately 65 minutes without DNA purification, thermal cycling, or specialized analytical equipment. CD-LAMP genotyping of samples was 100% concordant with accredited pathology genotyping on a panel of 40 blood and 20 saliva samples. In a panel of 100 purified DNA samples, genotyping of the high risk DQ2.5 genotype was 100% concordant with accredited pathology genotyping, with slightly reduced sensitivity for the DQ8 genotype (97.1%) and reduced specificity for the DQ8 (93.9%) and DQ2.2 (95.1%) genotypes. CD-LAMP results are easily visualized and instrument free through the addition of a DNA intercalating dye after amplification. Combined with point-of-care antibody testing, CD-LAMP may enable immediate, confident CD diagnosis at a low cost in the clinical setting. PMID- 29458096 TI - Identification of macrophage-related candidate genes in lupus nephritis using bioinformatics analysis. AB - Lupus nephritis (LN) is a chronic autoimmune disorder. Here we try to identify the candidate genes in macrophages related to LN. We performed a systematic search in the Gene Expression Omnibus (GEO) database for microarray in human mononuclear cells and mouse macrophages of LN. The results of clustering and venn analysis of different GEO datasets showed that 8 genes were up-regulated and 2 genes down-regulated in samples from both human and mouse LN. The data from gene network and GO analysis revealed that CD38 and CCL2 were localized in the core of the network. Immunofluorescence staining showed that CD38 expression was markedly increased in macrophages from kidneys with LN. Our study identifies the gene expression profile for macrophages and demonstrated the induction of CCL2 and CD38 in macrophages from patients with LN. However, regarding the limited patient number included in this study, the results are preliminary and more studies are still needed to further decipher the macrophage-related candidate genes for the pathogenesis of LN. PMID- 29458097 TI - Topographical memory analyzed in mice using the Hamlet test, a novel complex maze. AB - The Hamlet test is an innovative device providing a complex environment for testing topographic memory in mice. Animals were trained in groups for weeks in a small village with a central agora, streets expanding from it towards five functionalized houses, where they can drink, eat, hide, run, interact with a stranger mouse. Memory was tested by depriving mice from water or food and analyzing their ability to locate the Drink/Eat house. Exploration and memory were analyzed in different strains, gender, and after different training periods and delays. After 2 weeks training, differences in exploration patterns were observed between strains, but not gender. Neuroanatomical structures activated by training, identified using FosB/DeltaFosB immunolabelling, showed an involvement of the hippocampus-subiculum-parahippocampal gyrus axis and dopaminergic structures. Training increased hippocampal neurogenesis (cell proliferation and neuronal maturation) and modified the amnesic efficacy of muscarinic or nicotinic cholinergic antagonists. Moreover, topographical disorientation in Alzheimer's disease was addressed using intracerebroventricular injection of amyloid beta25 35 peptide in trained mice. When retested after 7 days, Abeta25-35-treated mice showed memory impairment. The Hamlet test specifically allows analysis of topographical memory in mice, based on complex environment. It offers an innovative tool for various ethological or pharmacological research needs. For instance, it allowed to examine topographical disorientation, a warning sign in Alzheimer's disease. PMID- 29458098 TI - Spermine protects from LPS-induced memory deficit via BDNF and TrkB activation. AB - Lipopolysaccharide (LPS) has been long known to promote neuroinflammation and learning and memory deficits. Since spermine, one of the main natural polyamines in the central nervous system, protects from LPS-induced memory deficit by a mechanism that comprises GluN2B receptors, the aim of the present study was to determine whether brain-derived neurotrophic factor (BDNF), tropomyosin-related kinase B (TrkB) receptor and cAMP response element binding (CREB) are involved in this protective effect of spermine. Adult male Swiss albino mice received, immediately after training in the novel object recognition task, saline or LPS (250 MUg/kg, i.p.); 5 min later they received saline or spermine (0.3 mg/kg, i.p.) and, when specified, 5 min thereafter saline or the TrkB receptor antagonist ANA-12 (0.5 mg/kg, i.p.) in different flanks. Animals were tested 24 h after training. Spermine protected from LPS-induced memory deficit and this protective effect was reversed by ANA-12. In a subset of animals BDNF, CREB and phospho-CREB immunoreactivity was determined in the hippocampi and cerebral cortex 4 h after spermine injection. Spermine reversed the decrease of mature BDNF levels induced by LPS in both hippocampus and cerebral cortex. Spermine increased phospho-CREB content and phospho-CREB/total CREB ratio in the cerebral cortex of LPS-treated mice. The results support that the protective effect of spermine on LPS-induced memory deficits depends on TrkB receptor activation and is accompanied by restoration of mature BDNF levels in hippocampus and cerebral cortex, as well as increased CREB phosphorylation in the cerebral cortex. PMID- 29458099 TI - Using near infrared spectroscopy to predict the lignin content and monosaccharide compositions of Pinus radiata wood cell walls. AB - Near infrared (NIR) spectroscopy coupled with partial least squares (PLS-1) regression was used to predict the lignin contents and monosaccharide compositions of milled wood of Pinus radiata. The effects of particle size and moisture content were investigated by collecting NIR spectra of four sample types: large (<0.422mm) and small (<0.178mm) particles, in both ambient and dry conditions. PLS-1 models were constructed using mixtures of compression wood (CW) and opposite wood (OW) that provided a linear range of cell-wall compositions. Our results show that lignin contents and monosaccharide compositions of pure CWs and OWs can be successfully predicted using NIR spectra of all four sample types. However, large particles in ambient conditions have the most efficient preparation and the standard error (SE) values for lignin (2.10%), arabinose (0.34%), xylose (1.33%), galactose (2.54%), glucose (6.98%), mannose (1.48%), galacturonic acid (0.22%), glucuronic acid (0.06%), and 4-O-methylglucuronic acid (0.25%) were achieved. PMID- 29458100 TI - Characterization and antioxidant activities of polysaccharides from thirteen boletus mushrooms. AB - Water-soluble polysaccharides were extracted from the caps and stipes of thirteen boletus mushrooms representing five different species collected in Southwest China. Investigations of their structures and antioxidant activities allowed an evaluation of structure-function relationships. The polysaccharides were composed mainly of the monosaccharides arabinose, xylose, mannose, glucose and galactose. Most samples displayed a broad molecular weight range, with significant differences observed between the molecular weight ranges of the polysaccharides from the caps and the stipes. FT-IR spectral analysis of the polysaccharides revealed that most of polysaccharides from boletus mushrooms (except Boletus edulis) contained a pyranose ring. The antioxidant activities of the polysaccharides in stipes showed a significant correlation with their monosaccharide composition, and were also related to their molecular weight and anomeric configuration. Suillellus luridus collected in Pingwu, Mianyang, Sichuan, China had remarkably superior antioxidant activity and might be developed as a natural antioxidant. PMID- 29458101 TI - Optimization of pectinase immobilization on grafted alginate-agar gel beads by 24 full factorial CCD and thermodynamic profiling for evaluating of operational covalent immobilization. AB - Pectinase produced by a honey derived from the fungus Aspergillus awamori KX943614 was covalently immobilized onto gel beads made of alginate and agar. Polyethyleneimine, glutaraldehyde, loading time and enzyme's units were optimized by 24 full factorial central composite design (CCD). The immobilization process increased the optimal working pH for the free pectinase from 5 to a broader range of pH4.5-5.5 and the optimum operational temperature from 55 degrees C to a higher temperature, of 60 degrees C, which is favored to reduce the enzyme's microbial contamination. The thermodynamics studies showed a thermal stability enhancement against high temperature for the immobilized formula. Moreover, an increase in half-lives and D-values was achieved. The thermodynamic studies proved that immobilization of pectinase made a remarkable increase in enthalpy and free energy because of enzyme stability enhancement. The reusability test revealed that 60% of pectinase's original activity was retained after 8 successive cycles. This gel formula may be convenient for immobilization of other industrial enzymes. PMID- 29458102 TI - gamma-Irradiated chitosan based injectable hydrogels for controlled release of drug (Montelukast sodium). AB - Novel pH-sensitive gamma-irradiated low molecular weight (MW) chitosan (CS) (pre irradiated) and poly (vinyl alcohol) (PVA) blended injectable hydrogels, crosslinked with varying concentrations of glycerol, were fabricated for drug delivery application. The effect of low MW irradiated CS on controlled drug release was evaluated to address the problem of higher viscosity and lower solubility of high MW CS. The FTIR spectra of hydrogels depicted the presence of all the incorporated functional groups and the developed interactions (physical and chemical). The surface morphology of hydrogels assessed by scanning electron microscope exhibited porous microstructure. All hydrogels were subjected to the swelling analysis in different media (water, buffer and electrolytes). The pH sensitive hydrogel samples exhibited less swelling at acidic and neutral pH while higher swelling at basic pH. CPG-0.5 showed the highest swelling at all pH media as compared to other hydrogel samples. CPG-1.0 was selected for the release analysis of drug because of its highest swelling (114.47%) in distilled water having neutral pH. It was loaded with model drug (Montelukast Sodium) during the preparation phase and studied for drug release capability. The in-vitro controlled release evaluation of hydrogel (CPG-1.0) was performed in SGF and SIF using UV-visible spectroscopy. The results confirmed their applications in injectable drug release systems as all the loaded drug was released in 30 min in SGF (pH -1.2) while the release of drug in SIF (pH -6.8) was in controlled manner (99.62% in 3 h). The improved antibacterial activity of these hydrogel films was owing to the fact that the gamma-irradiated low MW CS has ruptured the bacterial cell and its metabolism more efficiently by inflowing in the cell. PMID- 29458103 TI - Zinc oxide nanorod clusters deposited seaweed cellulose sheet for antimicrobial activity. AB - Seaweed cellulose was isolated from green seaweed Ulva fasciata using a common bleaching agent. Sheet containing porous mesh was prepared from the extracted seaweed crystalline cellulose along with zinc oxide (ZnO) nanorod clusters grown over the sheet by single step hydrothermal method. Seaweed cellulose and zinc oxide nanorod clusters deposited seaweed cellulose sheet was characterized by FT IR, XRD, TGA, and SEM-EDX. Morphology showed that the diameter of zinc oxide nanorods were around 70nm. Zinc oxide nanorod clusters deposited on seaweed cellulose sheet gave remarkable antibacterial activity towards gram-positive (Staphylococcus aureus, Bacillus ceresus, Streptococcus thermophilis) and gram negative (Escherichia coli, Pseudomonas aeruginous) microbes. Such deposited sheet has potential applications in pharmaceutical, biomedical, food packaging, water treatment and biotechnological industries. PMID- 29458104 TI - A new l-glutaminase from Streptomyces pratensis NRC 10: Gene identification, enzyme purification, and characterization. AB - In the current study, the purified l-glutaminase from Streptomyces pratensis NRC10 (GenBank number KC857622) was characterized. Its molecular weight was estimated to be 46kDa and isoelectric point 7.4. Its Vmax was calculated to be 2.19U/mg/min, while Km was 0.175mM. The optimum pH and temperature were 9 and 45 degrees C, respectively. It was thermostable at 45 degrees C but thermally inactivated at 60 degrees C after 50min. Moreover, its enzymatic activity was enhanced by K+ ions and inhibited by Mg2+, Cu2+, Ag+, Hg2+, Ni2+, Fe2+, Cr2, Na+, Ca2+, and EDTA. A PCR fragment of 1550bp of S. pratensis NRC10 l-glutaminase gene (glsA) was purified and its sequence was determined (GenBank number KJ567136). l glutaminase from NRC10 was induced mainly by l-glutamic acid. Model 3-D structure was composed of two domains, the serine - dependent beta-lactamase dominant the small STAS domain (Sulphate Transporter and anti-sigma factor antagonist) which had probably functioned as a general NTP binding domain. The two domains are linked by a linker peptide (GLHLMRNPALPGST), but sequence alignment between salt tolerant glutaminase and the obtained glutaminase showed 44.75% of identity and 57% of similarity. This enzyme appears to have a distinctive structure compared to the rest of glutaminase family, and seems to construct a new subgroup of glutaminase. PMID- 29458105 TI - Preparation and characterization of antibacterial, eco-friendly edible nanocomposite films containing Salvia macrosiphon and nanoclay. AB - Nowadays, food security is a vital issue and antimicrobial packaging could play an important role in this matter. In this regard, Salvia macrosiphon seed mucilage (SSM) and nanoclay, as new sources for the production of food-grade edible films were investigated. These edible films were prepared by incorporation of SSM with glycerol and different percentage of nanoclay. Upon addition of nanoclay up to 2% physical, mechanical and thermal properties were considerably improved and the composite films showed the lowest water vapor permeability (WVP), as well as highest elongation at break and tensile strength. The nanocomposite edible films also showed antibacterial activity due to the SSM nature. Addition of nanoclay, increased the hydrophobicity, which makes the films great alternatives for food packaging. This study revealed that these novel antimicrobial edible films could be a promising packaging option for a wide range of food products. PMID- 29458106 TI - Combi-metal organic framework (Combi-MOF) of alpha-amylase and glucoamylase for one pot starch hydrolysis. AB - The multi-enzyme biocatalyst allows to run in vitro multi-step cascade reactions in single pot. An efficient combi-metal organic frameworks (combi-MOF) of alpha amylase and glucoamylase for one pot starch hydrolysis was constructed by mixing zinc acetate and 2-methylimmidazole with enzyme mixture in one pot under biocompatible conditions. The prepared combi-MOF was characterized and analyzed by powder X-ray diffraction (PXRD), Fourier transform infrared (FT-IR), thermogravimetric analysis (TGA) and scanning electron microscopy (SEM). Thermo stability was evaluated for combi-MOF in the range of 55 to 75 degrees C which showed three folds improved stability in terms of half-life. In kinetic parameter studies, rate of starch hydrolysis (Vmax) of combi-MOF was found to be enhanced after co-immobilization. Further, combi-MOF was recycled in batch mode which retained up to 52% residual activity after five successive cycles of reuse. In addition to that, combi-MOF exhibited extraordinary storage stability till 24days. At the end, starch hydrolytic activity of combi-MOF was tested for different sources of starch (corn, rice, wheat and potato) which exhibited higher rate of hydrolysis than mixture of free enzymes due to spatially co-localized multi-enzymatic systems. PMID- 29458107 TI - WNT receptor signalling in lung physiology and pathology. AB - The WNT signalling cascades have emerged as critical regulators of a wide variety of biological aspects involved in lung development as well as in physiological and pathophysiological processes in the adult lung. WNTs (secreted glycoproteins) interact with various transmembrane receptors and co-receptors to activate signalling pathways that regulate transcriptional as well as non-transcriptional responses within cells. In physiological conditions, the majority of WNT receptors and co-receptors can be detected in the adult lung. However, dysregulation of WNT signalling pathways contributes to the development and progression of chronic lung pathologies, including idiopathic pulmonary fibrosis (IPF), chronic obstructive pulmonary disease (COPD), asthma and lung cancer. The interaction between a WNT and the (co-)receptor(s) present at the cell surface is the initial step in transducing an extracellular signal into an intracellular response. This proximal event in WNT signal transduction with (cell-specific) ligand-receptor interactions is of great interest as a potential target for pharmacological intervention. In this review we highlight the diverse expression of various WNT receptors and co-receptors in the aforementioned chronic lung diseases and discuss the currently available biologicals and pharmacological tools to modify proximal WNT signalling. PMID- 29458108 TI - The relaxin receptor as a therapeutic target - perspectives from evolution and drug targeting. AB - The peptide relaxin was first identified as an important circulating hormone during pregnancy over 90 years ago. Research over many years defined the numerous biological roles that relaxin plays throughout pregnancy in many mammalian species. These important biological actions have led to the testing of relaxin as a therapeutic agent for a number of indications. The discovery of the relaxin receptor, RXFP1, in 2002 facilitated the better understanding of the cellular targets of relaxin, its mechanism of action and enabled the development of relaxin mimetics and screening for small molecule agonists. Additionally, the rapid expansion of the genome databases and bioinformatics tools has significantly advanced our understanding of the evolution of the relaxin/RXFP1 signaling system. It is now clear that the relaxin-RXFP1 signaling axis is far more ancient than previously appreciated with important roles for invertebrate relaxin-like peptides in reproductive and non-reproductive functions. This review summarizes these advances as well as developments in drug targeting of RXFP1. Hence the complex mode of activation of RXFP1 is discussed as is the discovery and development of a peptide mimetic and small molecule agonist. Detailed signaling studies are summarized which highlight the cell specific signaling of a peptide mimetic and biased signaling of a small molecule agonist. These studies highlight the complexities of targeting peptide GPCRs such as RXFP1. PMID- 29458109 TI - Modulation of CYP1A1 metabolism: From adverse health effects to chemoprevention and therapeutic options. AB - The human cytochrome P450 (CYP) 1A1 gene encodes a monooxygenase that metabolizes multiple exogenous and endogenous substrates. CYP1A1 has become infamous for its oxidative metabolism of benzo[a]pyrene and related polycyclic aromatic hydrocarbons, converting these chemicals into very potent human carcinogens. CYP1A1 expression is mainly controlled by the aryl hydrocarbon receptor (AHR), a transcription factor whose activation is induced by binding of persistent organic pollutants, including polycyclic aromatic hydrocarbons and dioxins. Accordingly, induction of CYP1A1 expression and activity serves as a biomarker of AHR activation and associated xenobiotic metabolism as well as toxicity in diverse animal species and humans. Determination of CYP1A1 activity is integrated into modern toxicological concepts and testing guidelines, emphasizing the tremendous importance of this enzyme for risk assessment and regulation of chemicals. Further, CYP1A1 serves as a molecular target for chemoprevention of chemical carcinogenesis, although present literature is controversial on whether its inhibition or induction exerts beneficial effects. Regarding therapeutic applications, first anti-cancer prodrugs are available, which require a metabolic activation by CYP1A1, and thus enable a specific elimination of CYP1A1-positive tumors. However, the application range of these drugs may be limited due to the frequently observed downregulation of CYP1A1 in various human cancers, probably leading to a reduced metabolism of endogenous AHR ligands and a sustained activation of AHR and associated tumor-promoting responses. We here summarize the current knowledge on CYP1A1 as a key player in the metabolism of exogenous and endogenous substrates and as a promising target molecule for prevention and treatment of human malignancies. PMID- 29458110 TI - Investigation of adhesive interactions in the specific targeting of Triptorelin conjugated PEG-coated magnetite nanoparticles to breast cancer cells. AB - : The understanding of adhesive interaction at the nanoscale between functionalized nanoparticles and biological cells is of great importance to develop effective theranostic nanocarriers for targeted cancer therapy. Here, we report a combination of experimental and computational approaches to evaluate the adhesion between Triptorelin (a Luteinizing Hormone-Releasing Hormone (LHRH) agonist)-conjugated poly-(ethylene glycol) (PEG)-coated magnetite nanoparticles (Triptorelin-MNPs) and breast cells. The adhesion forces between Triptorelin-MNPs and normal/cancerous breast cells are obtained using atomic force microscopy. The corresponding work of adhesion is then estimated using Johnson-Kendall-Roberts model. Our results demonstrate that Triptorelin-MNPs have a fourteen-fold greater work of adhesion to breast cancer cells than to normal breast cells. In addition, the work of adhesion between Triptorelin-MNPs and breast cancer cells is found to be three times more than that between unmodified MNPs and breast cancer cells. Hence, the experimental observation indicates that Triptorelin ligands facilitate the specific targeting of breast cancer cells. Furthermore, molecular dynamics simulations are performed to investigate the molecular origins of the adhesive interactions. The simulations reveal that the interactions between molecules (e.g. Triptorelin and PEG) and LHRH receptors are dominated by van der Waals energies, while the interactions of these molecules with cell membrane are dominated by electrostatic interactions. Moreover, both experimental and computational results reveal that PEG serves as an effective coating that enhances adhesive interactions to breast cancer cells that over-express LHRH receptors, while reduces the adhesion to normal breast cells. Our results highlight the potential to develop Triptorelin-MNPs into tumor-specific MRI contrast agents and drug carriers. STATEMENT OF SIGNIFICANCE: Systematic investigation of adhesive interactions between functionalized nanoparticles and cancer cells is of great importance in developing effective theranostic nanocarriers for targeted cancer therapy. Herein, we use a combination of atomic force microscopy technique and molecular dynamics simulations approach to explore the adhesive interactions at the nanoscale between Triptorelin-conjugated polyethylene glycol (PEG)-coated magnetite nanoparticles and normal/cancerous breast cells. This study characterizes and quantifies the work of adhesion, as well as adhesion forces, at the nanocarrier/cell interfaces, unravels the molecular origins of adhesive interactions and highlights the effectiveness of PEG coatings and Triptorelin ligands in the specific targeting of breast cancer cells. Our findings expand the fundamental understanding of nanoparticle/cell adhesion and provide guidelines for the design of more rational nanocarriers.

AB - Duchenne muscular dystrophy (DMD) is a recessive, fatal X-linked disease that is characterized by progressive skeletal muscle wasting due to the absence of dystrophin, which is an a essential protein that bridges the inner cytoskeleton and extra-cellular matrix. This study set out to characterize the mitochondria in primary muscle satellite cell derived myoblasts from mdx mice and wild type control mice. Compared to wild type derived cells the mdx derived cells have reduced mitochondrial bioenergetics and have fewer mitochondria. Here, we demonstrate that a novel PPARdelta modulator improves mitochondrial function in the mdx mice, which supports that modulating PPARdelta may be therapeutically beneficial in DMD patients. PMID- 29458112 TI - Compatible osmolytes modulate mitochondrial function in a marine osmoconformer Crassostrea gigas (Thunberg, 1793). AB - Salinity is an important environmental factor affecting physiology of marine organisms. Osmoconformers such as marine mollusks maintain metabolic function despite changes of the osmolarity and composition of the cytosol during salinity shifts. Currently, metabolic responses to the salinity-induced changes of the intracellular milieu are not well understood. We studied the effects of osmolarity (450 vs. 900 mOsm) and compatible osmolytes (70-590 mM of taurine or betaine) on isolated gill mitochondria of a marine osmoconformer, the Pacific oyster Crassostrea gigas. Physiological concentrations of taurine enhanced mitochondrial ATP synthesis and electron transport system (ETS) capacity, increased mitochondrial coupling and stimulated the forward flux through the Complex I. Notably, the stimulatory effects of taurine were more pronounced at 900 mOsm compared to 450 mOsm. In contrast, betaine proportionally increased the rates of the mitochondrial proton leak, oxidative phosphorylation and ETS flux (with no net effect on the mitochondrial coupling) and suppressed the activity of cytochrome c oxidase in oyster mitochondria. However, the effective concentration of betaine (590 mM) was higher than typically found in bivalves, and thus betaine is not likely to affect oyster mitochondria under the physiological conditions in vivo. Our findings indicate that taurine may support the mitochondrial bioenergetics during hyperosmotic stress in oysters. Compatibility of taurine with the metabolic functions and its beneficial effects on mitochondria may have contributed to its broad distribution as an osmolyte in marine osmoconformers and might explain the earlier reports of the positive effects of taurine supplementation on energy metabolism of other organisms, including mammals. PMID- 29458113 TI - Poorer positive affect in response to self-paced exercise among the obese. AB - We aimed to investigate the association between body mass index (BMI) and affective response, ratings of perceived exertion (RPE), and physiological responses during self-paced exercise. Sixty-six women were divided into three groups accordingly with the BMI: obese (n = 22: 33.5 +/- 8.5 yr; 34.9 +/- 4.1 kg?m-2), overweight (n = 22: 34.8 +/- 8.6 yr; 26.4 +/- 1.3 kg?m-2), and normal weight (n = 22: 30.8 +/- 9.3 yr; 22.0 +/- 1.6 kg?m-2). They underwent a graded exercise test and a 20-min self-paced walking session on a treadmill. Affective responses, RPE, heart rate (HR), and oxygen uptake (VO2) were recorded every 5 min. The women with obesity experienced the lowest affective rates (p < .001), despite similar RPE, HR, and VO2 to the other normal weight and overweight groups. In addition, a multiple regression model indicated that BMI was a significant predictor of affective responses (p < .001). In conclusion, the results of the present study suggest that obesity is associated with poorer affective responses to exercise even at self-paced intensity, with the same physiological responses and perceived exertion. Therefore, techniques that aim directly to increase pleasure and/or reduce attentional focus and perception of effort in this population are required, such as affect-regulated prescription, shorter bouts of self-paced exercise throughout the day, distraction away from internal cues (e.g. music, group exercise), etc. PMID- 29458114 TI - Severity-dependent influence of isocapnic hypoxia on reaction time is independent of neurovascular coupling. AB - With exposure to acute normobaric hypoxia, global cerebral oxygen delivery is maintained via increases in cerebral blood flow (CBF); therefore, regional and localized changes in oxygen tension may explain neurocognitive impairment. Neurovascular coupling (NVC) is the close temporal and regional relationship of CBF to changes in neural activity and may aid in explaining the localized CBF response with cognitive activation. High-altitude related cognitive impairment is likely affected by hypocapnic cerebral vasoconstriction that may influence regional CBF regulation independent of hypoxia. We assessed neurocognition and NVC following 30 min of acute exposure to isocapnic hypoxia (decreased partial pressure of end-tidal oxygen; PETO2) during moderate hypoxia (MOD HX; 55 mm Hg PETO2), and severe hypoxia (SEV HX; 45 mm Hg PETO2) in 10 healthy individuals (25.5 +/- 3.3 yrs). Transcranial Doppler ultrasound was used to assess mean posterior and middle cerebral blood velocity (PCAv and MCAv, respectively) and neurocognitive performance was assessed via validated computerized tests. The main finding was that reaction time (i.e., kinesthetic and visual-motor ability via Stroop test) was selectively impaired in SEV HX (-4.6 +/- 5.2%, P = 0.04), but not MOD HX, while complex cognitive performance (e.g., psychomotor speed, cognitive flexibility, processing speed, executive function, and motor speed) was unaffected with hypoxia (P > 0.05). Additionally, severity of hypoxia had no effect on NVC (PCAv CON vs. SEV HX relative peak response 13.7 +/- 6.4% vs. 16.2 +/- 11.5%, P = 0.71, respectively). In summary, severe isocapnic hypoxia impaired reaction time, but not complex cognitive performance or NVC. These findings have implications for recreational and military personnel who may experience acute hypoxia. PMID- 29458115 TI - Effect of AceK (acesulfame potassium) on brain function under dietary restriction in mice. AB - People preferably take zero or low-calorie beverages and foods with artificial sweeteners even though it has been recently suggested that long-term artificial sweetener use affects physiological functions. In addition, a lower body weight was considered to be more healthful, but an abnormally low body weight caused by an excessive diet has been reported to cause health problems. Acesulfame potassium (AceK) is one of the most commonly used for foods and beverages because of its resistance to thermal degradation and marked sweetness. However, the combined effect of AceK and a low body weight on the physiological functions remains unknown. Here, we investigated the effect of long-term AceK fluid intake on the cognitive function under dietary restriction. We administered AceK to mice fed a low carbohydrate (LC) diet for 4 weeks, and behavioral assays were then performed for a week. The mice fed the LC diet with AceK treatment for 4 weeks showed an increase in water intake and a decrease in short-term and object cognitive memories in the Y-maze and novel object recognition tests, respectively. Mice were sacrificed after behavioral tests to measure glucose levels. The glucose levels in the frontal cortex were significantly decreased in mice fed the LC diet with AceK treatment in comparison with mice fed the LC diet alone, although there was no significant difference in the plasma glucose levels. These results suggest that the combination of long-term AceK intake and the LC diet affects the cognitive function through the reduction of cortical glucose levels. PMID- 29458116 TI - Junk food advertising moderates the indirect effect of reward sensitivity and food consumption via the urge to eat. AB - The current study aimed to identify how underlying individual differences increases vulnerability to television food advertising. In particular, this study examined how reward sensitivity, a biologically-based predisposition to approach rewards (such as appetitive foods) in the environment, influenced participants' vulnerability to television food advertising and subsequent food consumption. Ninety-eight participants were randomly assigned to a cue condition (food cues versus non-food cues) and then viewed a 30 min documentary interrupted by advertising featuring a mix of food and neutral advertising (food cue condition) or only neutral advertising (non-food cue condition). Participants' reward sensitivity, approach motivation measured as urge to eat, and food consumption were recorded. Moderated mediation regression analyses revealed the positive association between reward sensitivity and food consumption was mediated by an increase in urge to eat, but only when participants were exposed to food advertising. These findings suggest heightened reward sensitivity, exposure to appetitive food cues, and approach motivation are key interacting mechanisms that may lead to maladaptive eating behaviours. PMID- 29458117 TI - Agomelatine's effect on circadian locomotor rhythm alteration and depressive-like behavior in 6-OHDA lesioned rats. AB - Parkinson's disease (PD) patients often suffer from circadian locomotor rhythms impairment and depression, important non-motor symptoms. It is known that toxin based animal models of PD can reproduce these features. In a 6-hydroxydopamine (6 OHDA) intranigral model, we first investigated the possible disturbances on circadian rhythms of locomotor activity. The rats were divided into 6-OHDA and Sham groups. After a partial dopaminergic lesion, the 6-OHDA group showed slight alterations in different circadian locomotor rhythms parameters. In a second experiment, we hypothesized agomelatine, an melatoninergic antidepressant with potential to resynchronize disturbed rhythms, could prevent neuronal damage and rhythm alterations in the same 6-OHDA model. The animals were divided into four groups: 6-OHDA+vehicle, 6-OHDA+ago, Sham+vehicle and 6-OHDA+ago. However, the treated animals (agomelatine 50 mg/kg for 22 days) showed an impaired rhythm robustness, and agomelatine did not induce significant changes in the other circadian parameters nor neuroprotection. Finally, in a third experiment, we examined the effects of agomelatine in the 6-OHDA model regarding depressive-like behavior, evaluated by sucrose preference test. The animals were also divided into four groups: 6-OHDA+vehicle, 6-OHDA+ago, Sham+vehicle and 6-OHDA+ago. The toxin infused animals showed a decrease in sucrose preference in comparison with the vehicle infused animals, however, agomelatine did not prevent this decrease. Our findings indicate that agomelatine worsened circadian locomotor rhythm and was not able to reverse the depressive-like behavior of rats in the 6-OHDA PD model. PMID- 29458118 TI - Neuroprotective effect of melatonin against lipopolysaccharide-induced depressive like behavior in mice. AB - Accumulating evidence indicates an interaction between inflammation and depression since increased levels of pro-inflammatory cytokines are associated with depression-related symptoms. Melatonin is a hormone synthesized and secreted by the pineal gland with antioxidant, anti-inflammatory and antidepressant-like effects. In this way, it would be interesting to evaluate the putative antidepressant-like effect of melatonin treatment in an acute inflammation mice model of depression. The present study aimed to investigate the effect of melatonin treatment on lipopolysaccharide (LPS) induced depressive-like behavior, neuroinflammation, oxidative stress and alteration on brain-derived neurotrophic fator (BDNF) levels. Mice were treated with melatonin (10 mg/kg, i.p.) 30 min before LPS (0.5 mg/kg, i.p.) injection. Twenty-four hours after LPS infusion, mice were submitted to the behavioral tests and, thereafter, biochemical determinations were performed. Melatonin treatment prevented LPS-induced depressive-like behavior in the forced swim and tail suspension tests with no alterations in locomotor activity evaluated in the open field test. Melatonin attenuated LPS-induced increase in tumor necrosis factor-alpha (TNF-alpha) and reduction of BDNF levels in the hippocampus. Treatment with melatonin also prevented LPS-induced increase in lipid peroxidation and the reduction of glutathione levels in the hippocampus. In conclusion, the present study suggests that melatonin treatment exerted neuroprotective effects against LPS-induced depressive-like behavior which may be related to reduction of TNF-alpha release, oxidative stress and modulation of BDNF expression. PMID- 29458119 TI - The Function of HLA-B*13:01 Involved in the Pathomechanism of Dapsone-Induced Severe Cutaneous Adverse Reactions. AB - Dapsone-induced hypersensitivity reactions may cause severe cutaneous adverse reactions, such as drug reaction with eosinophilia and systemic symptoms (DRESS). It has been reported that HLA-B*13:01 is strongly associated with dapsone-induced hypersensitivity reactions among leprosy patients. However, the phenotype specificity and detailed immune mechanism of HLA-B*13:01 remain unclear. We investigated the genetic predisposition, HLA-B*13:01 function, and cytotoxic T cells involved in the pathogenesis of dapsone-induced severe cutaneous adverse reactions. We enrolled patients from Taiwan and Malaysia with DRESS and maculopapular eruption with chronic inflammatory dermatoses. Our results showed that the HLA-B*13:01 allele was present in 85.7% (6/7) of patients with dapsone DRESS (odds ratio = 49.64, 95% confidence interval = 5.89-418.13; corrected P = 2.92 * 10-4) but in only 10.8% (73/677) of general population control individuals in Taiwan. The level of granulysin, the severe cutaneous adverse reaction specific cytotoxic protein released from cytotoxic T cells, was increased in both the plasma of DRESS patients (36.14 +/- 9.02 ng/ml, P < 0.05) and in vitro lymphocyte activation test (71.4%, 5/7 patients) compared with healthy control individuals. Furthermore, dapsone-specific cytotoxic T cells were significantly activated when co-cultured with HLA-B*13:01-expressing antigen presenting cells in the presence of dapsone (3.9-fold increase, compared with cells with no HLA B*13:01 expression; P < 0.01). This study indicates that HLA-B*13:01 is strongly associated with dapsone DRESS and describes a functional role for the HLA restricted immune mechanism induced by dapsone. PMID- 29458120 TI - Major Role for TRPV1 and InsP3R in PAR2-Elicited Inflammatory Mediator Production in Differentiated Human Keratinocytes. AB - PAR2 activation in basal keratinocytes stimulates inflammation via the Ca2+ dependent production of mediators such as IL-1beta, TNF-alpha, and TSLP. In this study, we investigated PAR2 calcium signaling and the consequent production of inflammatory mediators in differentiated human primary keratinocytes (DhPKs). Stimulation with the PAR2-activating peptide SLIGKV promoted Ca2+ store depletion in both undifferentiated human primary keratinocytes and DhPKs. SLIGKV-evoked Ca2+ store depletion did not trigger the store-operated Ca2+ entry (i.e., SOCE) through ORAI1 in DhPKs compared with undifferentiated human primary keratinocytes. The inhibition of phospholipase C and the concomitant inhibition of TRPV1 and inositol triphosphate receptor in DhPKs abrogated the SLIGKV-evoked Ca2+ store depletion; NF-kappaB activity; and the production of inflammatory mediators such as IL-1beta, TNF-alpha, and TSLP. Taken together, these results indicate a key role for both InsP3R and TRPV1 in Ca2+ internal stores in the PAR2 evoked Ca2+ release and consequent skin inflammation in DhPKs. These findings may provide clues to understanding the pathological role of DhPKs in skin disorders in which PAR2 is known to be involved, such as atopic dermatitis, Netherton syndrome, and psoriasis. PMID- 29458121 TI - The paradox of marrow adipose tissue in anorexia nervosa. AB - Anorexia nervosa (AN) is a psychiatric disorder characterized by inappropriate nutrient intake resulting in low body weight. Multiple hormonal adaptations facilitate decreased energy expenditure in this state of caloric deprivation including non-thyroidal illness syndrome, growth hormone resistance, and hypogonadotropic hypogonadism. Although these hormonal adaptations confer a survival advantage during periods of negative energy balance, they contribute to the long-term medical complications associated with AN, the most common of which is significant bone loss and an increased risk of fracture. In recent years, marrow adipose tissue (MAT) has emerged as an important potential determinant of the low bone mass state characteristic of AN. Unlike subcutaneous and visceral adipose tissue depots which are low in AN, MAT levels are paradoxically elevated and are inversely associated with BMD. In this review, we discuss what is known about MAT in AN and the proposed hormonal determinants of this adipose tissue depot. PMID- 29458122 TI - Regional variations of cortical bone in the humeral head region: A preliminary study. AB - BACKGROUND: Incidence of proximal humeral fractures dramatically increased over the last decade due to demographic changes. The goal of this study was to analyze regional characteristics of cortical bone in the humeral head region using cortical bone mapping (CBM) technique. METHODS: The proximal humerus of 103 healthy volunteers was imaged by clinical computed tomography (CT) scans. Three groups of volunteers were identified according to age: group A (20-39years), group B (40-59years), and group C (>60years). CBM was applied to create color 3D thickness maps for each proximal humerus. Cortical parameters, including the cortical thickness (CTh), cortical mass surface density (CM), and the endocortical trabecular density (ECTD) were measured over humeral head region after nine regions of interest (ROI) were defined. RESULTS: Cortical bone structure of the humeral head region varied dramatically in cross-section independent of age, with significant cortical thinning at the posterior wall. Particularly, notable cortical thinning was also found in the distal end of lateral wall at 60years of age or older. The degree of regional variability of cortical properties within lateral wall tended to diminish with age. CONCLUSION: Substantial regional variations in cortical bone structure at humeral head region were observed quantitatively in this study. These morphologic data provided useful information on clinical medicine such as surgical fixation. PMID- 29458123 TI - Osteocyte regulation of bone and blood. AB - This past decade has witnessed a renewed interest in the function and biology of matrix-embedded osteocytes and these cells have emerged as master regulators of bone homeostasis. They secrete two very powerful proteins, sclerostin, a Wnt inhibitor, that suppresses bone formation, and receptor-activator of NF-kB ligand (RANKL), a cytokine required for osteoclastogenesis. Neutralizing antibodies against these proteins are currently used for the treatment of osteoporosis. Recent studies however, ascribed yet another function to osteocytes: the control of hematopoiesis and the HSPC niche, directly and through secreted factors. In the absence of osteocytes there is an increase in HSC mobilization and abnormal lymphopoiesis whereas in the absence of Gsalpha signaling in these cells there is an increase of myeloid cells. How exactly osteocytes control hematopoiesis or the HSPC niche is still not completely understood. In this review we summarize the actions of osteocytes in bone and then analyze the effects of these cells on hematopoiesis. Future directions and gaps in current knowledge are further discussed. PMID- 29458124 TI - Tryptophan-mediated Dimerization of the TssL Transmembrane Anchor Is Required for Type VI Secretion System Activity. AB - The type VI secretion system (T6SS) is a multiprotein complex used by bacteria to deliver effectors into target cells. The T6SS comprises a bacteriophage-like contractile tail structure anchored to the cell envelope by a membrane complex constituted of the TssJ outer-membrane lipoprotein and the TssL and TssM inner membrane proteins. TssJ establishes contact with the periplasmic domain of TssM whereas the transmembrane segments of TssM and its cytoplasmic domain interact with TssL. TssL protrudes in the cytoplasm but is anchored by a C-terminal transmembrane helix (TMH). Here, we show that TssL TMH dimerization is required for the stability of the protein and for T6SS function. Using the TOXCAT assay and point mutations of the 23 residues of the TssL TMH, we identified Thr194 and Trp199 as necessary for TssL TMH dimerization. NMR hydrogen-deuterium exchange experiments demonstrated the existence of a dimer with the presence of Trp185 and Trp199 at the interface. A structural model based on molecular dynamic simulations shows that TssL TMH dimer formation involves pi-pi interactions resulting from the packing of the two Trp199 rings at the C-terminus and of the six aromatic rings of Tyr184, Trp185 and Trp188 at the N-terminus of the TMH. PMID- 29458125 TI - Pluripotent Stem Cells for Uncovering the Role of Mitochondria in Human Brain Function and Dysfunction. AB - Mitochondrial dysfunctions are a known pathogenetic mechanism of a number of neurological and psychiatric disorders. At the same time, mutations in genes encoding for components of the mitochondrial respiratory chain cause mitochondrial diseases, which commonly exhibit neurological symptoms. Mitochondria are therefore critical for the functionality of the human nervous system. The importance of mitochondria stems from their key roles in cellular metabolism, calcium handling, redox and protein homeostasis, and overall cellular homeostasis through their dynamic network. Here, we describe how the use of pluripotent stem cells (PSCs) may help in addressing the physiological and pathological relevance of mitochondria for the human nervous system. PSCs allow the generation of patient-derived neurons and glia and the identification of gene specific and mutation-specific cellular phenotypes via genome engineering approaches. We discuss the recent advances in PSC-based modeling of brain diseases and the current challenges of the field. We anticipate that the careful use of PSCs will improve our understanding of the impact of mitochondria in neurological and psychiatric disorders and the search for effective therapeutic avenues. PMID- 29458127 TI - Calmodulin-induced Conformational Control and Allostery Underlying Neuronal Nitric Oxide Synthase Activation. AB - Nitric oxide synthase (NOS) is the primary generator of nitric oxide signals controlling diverse physiological processes such as neurotransmission and vasodilation. NOS activation is contingent on Ca2+/calmodulin binding at a linker between its oxygenase and reductase domains to induce large conformational changes that orchestrate inter-domain electron transfer. However, the structural dynamics underlying activation of full-length NOS remain ambiguous. Employing hydrogen-deuterium exchange mass spectrometry, we reveal mechanisms underlying neuronal NOS activation by calmodulin and regulation by phosphorylation. We demonstrate that calmodulin binding orders the junction between reductase and oxygenase domains, exposes the FMN subdomain, and elicits a more dynamic oxygenase active site. Furthermore, we demonstrate that phosphorylation partially mimics calmodulin activation to modulate neuronal NOS activity via long-range allostery. Calmodulin binding and phosphorylation ultimately promote a more dynamic holoenzyme while coordinating inter-domain communication and electron transfer. PMID- 29458128 TI - Aggregation-prone Regions in HYPK Help It to Form Sequestration Complex for Toxic Protein Aggregates. AB - Protein aggregates result from altered structural conformations and they can perturb cellular homeostasis. Prevention mechanisms, which function against protein aggregation by modulatory processes, are diverse and redundant. In this study, we have characterized Huntingtin interacting protein K (HYPK) as a global aggregation-regulatory protein. We report the mechanistic details of how HYPK's aggregation-prone regions allow it to sense and prevent other toxic protein's aggregation by forming unique annular-shaped sequestration complexes. Screenings for interacting partners of different aggregation-prone proteins identify HYPK as a global interacting partner/regulator of Huntingtin97Qexon1, alpha-Synuclein A53T and Superoxide dismutase1-G93A. C-terminal hydrophobic region in HYPK makes direct contacts with aggregates to initiate the formation of sequestration complexes. HYPK acts as aggregate sensor by existing in a seeded amyloid-like state which also favors its own concentration-dependent self-oligomerization. Oligomerization of HYPK leads to annular and non-fibrillar/amorphous aggregates. Two hydrophobic segments in the C-terminus of HYPK are responsible for its own aggregations. Self-association of HYPK follows seed nucleation, in which oligomeric HYPK seeds nucleate to annular structures. Annular oligomers of HYPK fuse with each other to form amorphous aggregates. HYPK shows differential interactions with aggregation-prone and non-aggregating proteins, as it preferentially binds to aggregation-prone proteins with higher affinity than native/non-aggregating proteins. This favors the formation of HYPK's sequestration complexes both in cytosol and in ribosome. Besides having aggregation-preventive property, HYPK also reduces the cellular level of toxic proteins. In vivo, HYPK sequestration complexes prevent the formation of toxic protein aggregates to physiologically show positive impact on cell survival and restoration of normal cell physiology. PMID- 29458126 TI - Structural and Mechanistic Analysis of the Choline Sulfatase from Sinorhizobium melliloti: A Class I Sulfatase Specific for an Alkyl Sulfate Ester. AB - Hydrolysis of organic sulfate esters proceeds by two distinct mechanisms, water attacking at either sulfur (S-O bond cleavage) or carbon (C-O bond cleavage). In primary and secondary alkyl sulfates, attack at carbon is favored, whereas in aromatic sulfates and sulfated sugars, attack at sulfur is preferred. This mechanistic distinction is mirrored in the classification of enzymes that catalyze sulfate ester hydrolysis: arylsulfatases (ASs) catalyze S-O cleavage in sulfate sugars and arylsulfates, and alkyl sulfatases break the C-O bond of alkyl sulfates. Sinorhizobium meliloti choline sulfatase (SmCS) efficiently catalyzes the hydrolysis of alkyl sulfate choline-O-sulfate (kcat/KM=4.8*103s-1M-1) as well as arylsulfate 4-nitrophenyl sulfate (kcat/KM=12s-1M-1). Its 2.8-A resolution X ray structure shows a buried, largely hydrophobic active site in which a conserved glutamate (Glu386) plays a role in recognition of the quaternary ammonium group of the choline substrate. SmCS structurally resembles members of the alkaline phosphatase superfamily, being most closely related to dimeric ASs and tetrameric phosphonate monoester hydrolases. Although >70% of the amino acids between protomers align structurally (RMSDs 1.79-1.99A), the oligomeric structures show distinctly different packing and protomer-protomer interfaces. The latter also play an important role in active site formation. Mutagenesis of the conserved active site residues typical for ASs, H218O-labeling studies and the observation of catalytically promiscuous behavior toward phosphoesters confirm the close relation to alkaline phosphatase superfamily members and suggest that SmCS is an AS that catalyzes S-O cleavage in alkyl sulfate esters with extreme catalytic proficiency. PMID- 29458129 TI - Honeysuckle-encoded microRNA2911 inhibits Enterovirus 71 replication via targeting VP1 gene. AB - Enterovirus 71 (EV71) is the primary pathogen of hand-foot-and-mouth disease (HFMD) in children and virus infections are associated with severe neurological dysfunctions and even death. MIR2911 is a honeysuckle-encoded atypical microRNA with extreme stability. Here, we report that MIR2911 directly inhibits EV71 replication by targeting the VP1 gene. Bioinformatics prediction and luciferase reporter assay showed that MIR2911 could target the VP1 gene of EV71. Transfection experiments using synthetic MIR2911 and extracted RNA from HS decoction shown that each of these preparations was capable of inhibiting EV71 VP1 protein expression; however, these preparations did not impact EV71 mutants in which the MIR2911-binding sites were mutated. Furthermore, EV71 replication was increased by antagomirs against MIR2911 in the HS decoction, implying that MIR2911 was physiologically functional in controlling EV71 replication in vitro. These results indicated that, by targeting VP1 gene, MIR2911 may effectively inhibit EV71 replication. Our results also provide a potential novel strategy on the therapy and/or prevention of HFMD originating from EV71 virus infection. PMID- 29458130 TI - Impact of RNA polymerase I inhibitor CX-5461 on viral kinase-dependent and independent cytomegalovirus replication. AB - Human cytomegalovirus (HCMV) infections cause congenital birth defects and disease in immunosuppressed individuals. Antiviral compounds can control infection yet their use is restricted due to concerns of toxicity and the emergence of drug resistant strains. We have evaluated the impact of an RNA Polymerase I (Pol I) inhibitor, CX-5461 on HCMV replication. CX-5461 inhibits Pol I-mediated ribosomal DNA transcription by binding G-quadruplex DNA structures and also activates cellular stress response pathways. The addition of CX-5461 at both early and late stages of the HCMV infection inhibited viral DNA synthesis and virus production. Interestingly, adding CX-5461 after the onset of viral DNA synthesis resulted in a greater reduction compared to continuous treatment starting early during infection. We observed an accompanying increase in cyclin dependent kinase inhibitor p21 in infected cells treated late but not early which likely explains the differences. Our previous studies demonstrated the importance of p21 in the antiviral activity of the HCMV kinase inhibitor, maribavir. Addition of CX-5461 increased the anti-HCMV activity of maribavir. Our data demonstrate that CX-5461 inhibits HCMV replication and synergizes with maribavir to disrupt infection.

AB - Chronic hepatitis B virus (HBV) infection is difficult to cure due to the presence of covalently closed circular DNA (cccDNA). Accumulating evidence indicates that the CRISPR/Cas9 system effectively disrupts HBV genome, including cccDNA, in vitro and in vivo. However, efficient delivery of CRISPR/Cas9 system to the liver or hepatocytes using an adeno-associated virus (AAV) vector remains challenging due to the large size of Cas9 from Streptococcus pyogenes (Sp). The recently identified Cas9 protein from Staphylococcus aureus (Sa) is smaller than SpCas9 and thus is able to be packaged into the AAV vector. To examine the efficacy of SaCas9 system on HBV genome destruction, we designed 5 guide RNAs (gRNAs) that targeted different HBV genotypes, 3 of which were shown to be effective. The SaCas9 system significantly reduced HBV antigen expression, as well as pgRNA and cccDNA levels, in Huh7, HepG2.2.15 and HepAD38 cells. The dual expression of gRNAs/SaCas9 in these cell lines resulted in more efficient HBV genome cleavage. In the mouse model, hydrodynamic injection of gRNA/SaCas9 plasmids resulted in significantly lower levels of HBV protein expression. We also delivered the SaCas9 system into mice with persistent HBV replication using an AAV vector. Both the AAV vector and the mRNA of Cas9 could be detected in the C3H mouse liver cells. Decreased hepatitis B surface antigen (HBsAg), HBV DNA and pgRNA levels were observed when a higher titer of AAV was injected, although this decrease was not significantly different from the control. In summary, the SaCas9 system accurately and efficiently targeted the HBV genome and inhibited HBV replication both in vitro and in vivo. The system was delivered by an AAV vector and maybe used as a novel therapeutic strategy against chronic HBV infection. PMID- 29458132 TI - Therapeutic drug monitoring in treatment-experienced HIV-infected patients receiving darunavir-based salvage regimens: A case series. AB - Therapeutic drug monitoring (TDM) constitutes a compelling approach for the optimization of antiretroviral therapy in treatment-experienced HIV-1 patients. While various inhibitory indices have been proposed to predict virologic outcome, there is a lack of consensus on the clinical value of TDM. Here, we report the comparative results of TDM in 14 HIV-1-infected patients who had previously received at least two different PI-based regimens and who initiated darunavir (DRV)-based salvage therapy. Pharmacokinetic/pharmacodynamics (PK/PD) parameters were calculated for each subject. Seventy-nine percent of subjects had a viral load <50 copies/mL at 48 weeks. The only subject with two consecutive viral loads >50 copies/mL at the end of the study period was the patient with the lowest instantaneous inhibitory potential (IIP). The sample size was insufficient to show an association between any of the PK/PD parameters and virologic response. Based on our observations, we suggest that the utility of IIP for antiretroviral combinations for the prediction of virologic outcome in HIV-1 drug-experienced patients should be studied further. PMID- 29458133 TI - Artesunate-derived monomeric, dimeric and trimeric experimental drugs - Their unique mechanistic basis and pronounced antiherpesviral activity. AB - Human cytomegalovirus (HCMV) is a major human pathogen and is associated with severe pathology, such as life-threatening courses of infection in immunocompromised individuals and neonates. Currently, antiviral therapy is still hampered by a considerable toxicity of the available drugs and induction of viral resistance. Recently, we and others reported the very potent antiviral activity of the broad antiinfective drug artesunate in vitro and in vivo. Here, we investigated further optimized analogs including monomeric, dimeric and trimeric derivatives belonging to this highly interesting chemical group of experimental drugs (sesquiterpenes/trioxanes) and compared these to the previously identified trimeric artesunate compound TF27. We could demonstrate that (i) seven of the eight investigated monomeric, dimeric and trimeric artesunate derivatives, i.e. TF79, TF85, TF87, TF93.2.4, TF111, TF57a and TF57ab, exerted a strong anti-HCMV activity in primary human fibroblasts, (ii) the EC50 values ranged in the low to sub-micromolar concentrations and indicated a higher antiviral potency than the recently described artesunate analogs, (iii) one trimeric compound, TF79, showed a very promising EC50 of 0.03 +/- 0.00 MUM, which even exceled the antiviral potency of TF27 (EC50 0.04 +/- 0.01 MUM), (iv) levels of cytotoxicity (quantitative measurement of lactate dehydrogenase release) were low in a range between 100 and 30 MUM and thus different from antiviral concentrations, (v) an analysis of protein expression levels indicated a potent block of viral protein expression, and (vi) data from a NF-kappaB reporter cell system strongly suggested that these compounds share the same antiviral mechanism. Taken together, our data on these novel compounds strongly encourages our earlier concept on the oligomerization and hybridization of artesunate analogs, providing an excellent platform for the generation of antiherpesviral drugs. PMID- 29458134 TI - Antiviral activity of pyrrole-imidazole polyamides against SV40 and BK polyomaviruses. AB - The ability of antiviral polyamides (AVP) to act upon polyomaviruses (PyV) was evaluated. Initial studies found that a single treatment of AVP protected SV40 infected BSC-1 cells from cytopathic effect (CPE) for as long as 11 days p.i.. AVP substantially suppressed SV40 genome copy numbers over the duration of the experiment. Immunofluorescence analysis of ataxia-telangiectasia mutated (ATM) activation and large T antigen (LTag) expression clearly demonstrated that AVP treatment at day 1 p.i. delayed the onset of productive SV40 replication by approximately 3 days, and substantially limited the infection relative to vehicle treated controls. AVP dose-response experiments recorded IC50s in the low nM range that were similar to IC50s previously reported for HPV16. The ability of AVPs to act on BKPyV was next examined. Again, IC50s in the low nM range were obtained with the exception of an AVP (PA1) that gave an IC50 of 437 nM against the BKPyV Dunlop strain. The Mre11 inhibitor Mirin substantially reduced the AVP IC50 against SV40 demonstrating that Mre11 protects PyV genomes from AVP action as previously shown for HPV. Together these experiments show that AVPs are potent antiviral agents for PyV that act via a mechanism with similarities to that found for HPV. The results demonstrate that AVPs are useful tools for controlling and studying PyV biology. The potential use of these agents against BKPyV and other PyV pathogens also has clinical implications. PMID- 29458135 TI - Porcine heart interatrial septum anatomy. AB - BACKGROUND: The left-sided atrial septal pouch (SP), a recently re-discovered anatomical structure within the human interatrial septum, has emerged as a possible source of thrombi formation and a trigger for atrial fibrillation, thereby potentially increasing the risk for ischemic stroke. In many studies, the swine interatrial septum has been used as model of the human heart. Also, possible new strategies and devices for management of the SPs may first be tested in this pig model. Therefore, in this study, we aimed to evaluate swine interatrial septum morphology and to compare it with the human analog, especially in the light of SP occurrence. METHODS: A total of 75 swine (Sus scrofa f. domestica) hearts were examined. The interatrial septum morphology was assessed, and SPs were measured. RESULTS: The most common variant of the interatrial septum was smooth septum (26.6%) followed by the patent foramen ovale channel and right SP (both 22.7%). No left or double SPs were observed. In 28.0% of all cases the fold of tissue (left septal ridge) was observed on the left side of the interatrial septum in the location where the left-sided SP should be expected. The mean length of the patent foramen ovale channel was 7.1+/-1.5mm. The mean right SP depth was 6.3+/-2.2mm, and its ostium width and height were 5.8+/-1.2 and 5.3+/-1.6mm, respectively. CONCLUSIONS: There are significant differences between human and porcine interatrial septum morphology that should be taken into account during experimental studies. The absence of the left SP in swine results in the inability to use porcine heart as an experimental model for left-sided SP management. PMID- 29458136 TI - Changes in anatomic position of root canal orifices in pluriradicular teeth following re-location during endodontic treatment. AB - Direct access to the root canals in posterior teeth for endodontic treatment is most frequently facilitated by the straightening of the coronal parts of the root canals, having as a consequence the relocation of the canal orifices on the map of the floor of the pulp chamber (Christie and Thompson, 1994). This procedure intentionally moves the coronal aspect of a canal away from the center of the chamber, while simultaneously removing internal dentin from the pulp chamber walls. The aim of this study was to evaluate the displacement resulting from the relocation of root canal orifices during the initial phase of rotary root canal treatment in molars using the dental operating microscope (DOM) and digital image processing. Forty-three molars (17 maxillary and 26 mandibular) belonging to 43 patients (aged 18-62 years) with indications for root canal treatment were endodontically treated. The differences between the initial perimeter and the perimeter of the root canal orifices polygon after relocation varied between 2.7 and 3.4MUm (mean 3.0MUm), while the differences between the initial area and the area after relocation varied between 2,448,456.8 and 3,249,306.6MUm2 (mean 2,848,881.7). The increase in access to the cavities and the alterations of the pulp chambers can be satisfactorily approximated by the variations of the perimeters and areas of the pulp floor polygons during root canal treatment. From a clinical perspective, these results indicate that there is a significant decrease in tooth substance in molars (except MB2). PMID- 29458137 TI - Bisphenol A alters oocyte maturation by prematurely closing gap junctions in the cumulus cell-oocyte complex. AB - In ovarian follicles, cumulus cells communicate with the oocyte through gap junction intercellular communication (GJIC), to nurture the oocyte and control its meiosis arrest and division. Bisphenol A (BPA) is a monomer found in polycarbonate-made containers that can induce functional alterations, including impaired oocyte meiotic division and reduced molecule transfer in GJIC. However, how BPA alters oocyte meiotic division is unclear. We investigated whether BPA effects on oocyte meiotic division were correlated with reduced transfer in GJIC. Cumulus cell-oocyte complexes (COCs) isolated from mouse preovulatory follicles were cultured with 0, 0.22, 2.2, 22, 220, and 2200 nM BPA for 2 h. An additional 16-h incubation with epidermal growth factor (EGF) was performed to promote the occurrence of meiotic resumption and progression to metaphase II. Without EGF stimulus, BPA treatment increased the percentage of oocytes undergoing meiotic resumption, decreased GJIC in the COCs, and did not modify GJIC gene (Cx43 and Cx37) and protein (CX43) expression. Following EGF stimulus, BPA increased the percentage of oocytes that remained at the anaphase and telophase stages, and decreased the percentage of oocytes reaching the metaphase II stage. Concomitantly, BPA reduced the expansion of cumulus cells. Carbenoxolone (a GJIC inhibitor) and 6-diazo-5-oxo-l-norleucine (a cumulus cell-expansion inhibitor) exerted effects on meiotic division similar to those exerted by BPA. These data suggest that BPA accelerates meiotic progression, leading to impaired prophase I to-metaphase II transition, and that this adverse effect is correlated with reduced bidirectional communication in the COC. PMID- 29458138 TI - Pharmacokinetic and pharmacodynamic evaluation of 5-methoxy-2-aminoindane (MEAI): A new binge-mitigating agent. AB - 5-Methoxy-2-aminoindane (MEAI) is a novel psychoactive aminoindane derivative, exerting euphoric, alcohol-like tipsy experience and reduced desire to consume alcoholic beverages. Our previous toxicological evaluation of MEAI in rats, clearly indicated MEAI's potential to be further evaluated as a promising binge mitigating agent due to its favorable safety profile. In the light of these observations, we have determined MEAI's pharmacokinetic (PK) profile in rats and evaluated in-vitro its pharmacodynamics (PD) profile. Following oral and intravenous administration of MEAI, two metabolites were identified, namely, N acetyl-MEAI and 5-hydroxy-N-acetyl-AI, arising from N-acetylation and oxidative demethylation. The PK-parameters of MEAI and N-acetyl-MEAI were derived from single i.v. bolus (10 mg/kg) and single oral doses (10 and 90 mg/kg) of MEAI to rats. MEAI displayed extensive total clearance (2.8 L/h/kg) and a very short plasma and brain half-life (0.5-0.7 h). At 10 mg/kg, MEAI displayed low oral bioavailability (25%) and a plasma to brain ratio in the range of 3-5.5, with brain MEAI peak levels attained rapidly. Non-linear pharmacokinetic behavior was observed in the 90 mg/kg oral group, in which the bioavailability increased by 500%. The non-linear behavior was also evident by the significant increase in plasma half-life of MEAI and its metabolite, N-acetyl-MEAI. N-acetyl-MEAI levels in plasma and brain were about ten times lower than the parent compound, indicative of its minor contribution to MEAI's pharmacological effect. MEAI displayed weak to moderate ligand binding inhibition at the 5-HT2B receptor, while the remaining neurochemical targets were unaffected. Further studies, in non-rodent species are required, in-order to assess MEAI's PK and PD profile adequately. PMID- 29458139 TI - Molecular and tissue alterations of collagens in fibrosis. AB - The collagen network is altered in fibrotic diseases associated with extracellular matrix (ECM) biosynthesis and remodeling. This mini-review focuses on the quantitative and qualitative modifications of collagens occurring at the molecular and tissue levels in fibrosis. They result from changes in collagen expression, biosynthesis, enzymatic cross-linking and degradation by several protease families. These molecular modifications, which are mostly regulated by TGF-beta, are associated with altered collagen organization at the tissue level, leading to a fibrotic signature that can be analyzed by Second Harmonic Generation (SHG) microscopy. PMID- 29458140 TI - Hyaluronan in adipogenesis, adipose tissue physiology and systemic metabolism. AB - Hyaluronic acid (HA, also known as hyaluronan), is a non-sulfated linear glycosaminoglycan polymer consisting of repeating disaccharide units of d glucuronic acid and N-acetyl-d-glucosamine abundantly present in the extracellular matrix. The sizes of hyaluronic acid polymers range from 5000 to 20,000,000 Da in vivo, and the functions of HA are largely dictated by its size. Due to its high biocompatibility, HA has been commonly used as soft tissue filler as well as a major component of biomaterial scaffolds in tissue engineering. Several studies have implicated that HA may promote differentiation of adipose tissue derived stem cells in vitro or in vivo when used as a supporting scaffold. However, whether HA actually promotes adipogenesis in vivo and the subsequent metabolic effects of this process are unclear. This review summarizes some recent publications in the field and discusses the possible directions and approaches for future studies, focusing on the role of HA in the adipose tissue. PMID- 29458141 TI - Long non-coding RNAs within the tumour microenvironment and their role in tumour stroma cross-talk. AB - Long non-coding RNAs (lncRNAs) are a diverse class of RNA transcripts which have limited protein coding potential. They perform a variety of cellular functions in health, but have also been implicated during malignant transformation. A further theme in recent years is the critical role of the tumour microenvironment and the dynamic interactions between cancer and stromal cells in promoting invasion and disease progression. Whereas the contribution of deregulated lncRNAs within cancer cells has received considerable attention, their significance within the tumour microenvironment is less well understood. The tumour microenvironment consists of cancer-associated stromal cells and structural extracellular components which interact with one another and with the transformed epithelium via complex extracellular signalling pathways. LncRNAs are directly and indirectly involved in tumour/stroma cross-talk and help stimulate a permissive tumour microenvironment which is more conducive for invasive tumour growth. Furthermore, lncRNAs play key roles in determining the phenotype of cancer associated stromal cells and contribute to angiogenesis and immune evasion pathways, extracellular-matrix (ECM) turnover and the response to hypoxic stress. Here we explore the multifaceted roles of lncRNAs within the tumour microenvironment and their putative pathophysiological effects. PMID- 29458142 TI - Insufficient radiofrequency ablation promotes proliferation of residual hepatocellular carcinoma via autophagy. AB - Radiofrequency ablation (RFA) is considered to be a potentially curative therapy for hepatocellular carcinoma (HCC). However, insufficient RFA (IRFA) can promote rapid progression of the residual tumor. The mechanisms underlying IRFA-induced tumor promotion remain poorly understood. In the present study, we have established a subcutaneous xenograft mouse model and monitored the location and extent of IRFA by dual monitoring with ultrasonography and a thermal imager. For the first time, we provide evidence of the activation of autophagic pathways in mice exposed to IRFA. We show that autophagy plays an important role in relapse and proliferation after IRFA and that hydroxychloroquine (HCQ) can suppress these effects. Our findings indicate that autophagy is involved in experimental IRFA and that inhibition of autophagy may be a novel approach in the treatment of local recurrences of HCC after IRFA in the clinic. PMID- 29458143 TI - SUV39H2 promotes colorectal cancer proliferation and metastasis via tri methylation of the SLIT1 promoter. AB - Suppressor of variegation 3-9 homolog 2 (SUV39H2) is a member of the SUV39H subfamily of lysine methyltransferases. Its role in colorectal cancer (CRC) proliferation and metastasis has remained unexplored. Here, we determined that SUV39H2 was upregulated in CRC tissues compared with that in adjacent non neoplastic tissues. Further statistical analysis revealed that high SUV39H2 expression was strongly associated with distant metastasis (P = 0.016) and TNM stage (P = 0.038) and predicted a shorter overall survival (OS; P = 0.018) and progression-free survival (PFS; P = 0.018) time for CRC patients. Both in vitro and in vivo assays demonstrated that ectopically expressed SUV39H2 enhanced CRC proliferation and metastasis, while SUV39H2 knockdown inhibited CRC proliferation and metastasis. A molecular screen of SUV39H2 targets found that SUV39H2 negatively regulated the expression of SLIT guidance ligand 1 (SLIT1). Moreover, rescue assays suggested that SLIT1 could antagonize the function of SUV39H2 in CRC. Mechanistic studies indicated that SUV39H2 can directly bind to the SLIT1 promoter, suppressing SLIT1 transcription by catalyzing histone H3 lysine 9 (H3K9) tri-methylation. In summary, we propose that SUV39H2 can predict CRC patient prognosis and stimulate CRC malignant phenotypes via SLIT1 promoter tri methylation. PMID- 29458144 TI - Disruption of peroxisome function leads to metabolic stress, mTOR inhibition, and lethality in liver cancer cells. AB - Peroxisome houses a large number of enzymes involved in lipid and phytochemical oxidation as well as synthesis of bile acid and other specialized lipids. Peroxisome resident enzymes are imported into the organelle via a conserved cargo transport system composed of many peroxins, protein factors essential for the biogenesis of peroxisome. Among the peroxins, PEX5 plays a transporter role, and PEX2, 10, and 12 are thought to form a complex that functions as an E3 ubiquitin ligase to help recycle PEX5 in an ubiquitin modification-dependent process. Previous studies have demonstrated the importance of peroxins in postnatal development especially the development of nerve systems. These studies also show that peroxins or the function of peroxisomes is dispensable for cellular viability. In contrast, however, we report here that PEX2 and other peroxins are essential for the viability of liver cancer cells, probably through altering metabolism and signaling pathways. Our results suggest that peroxins may be potential targets of therapeutics against liver cancer. PMID- 29458145 TI - The C/EBPbeta-LINC01133 axis promotes cell proliferation in pancreatic ductal adenocarcinoma through upregulation of CCNG1. AB - Long non-coding RNAs (lncRNAs) are emerging as important regulators and prognostic markers of multiple cancers. Our aim was to determine functional involvement of lncRNAs in pancreatic ductal adenocarcinoma (PDAC). In this study, we report that LINC01133 expression is higher in PDAC tissues compared to adjacent non-cancerous tissues, and this overexpression is associated with poorer prognosis among the patients. In vitro, a knockdown of LINC01133 substantially decreased PDAC cell proliferation. Tumorigenicity of PDAC cells with the LINC01133 knockdown was significantly impaired in a xenograft model assay. Moreover, we determined that CCAAT/enhancer-binding protein beta (C/EBPbeta) positively regulates LINC01133 expression by binding to the response elements within the LINC01133 promoter. Higher expression of C/EBPbeta was observed in PDAC tissues, and this overexpression was also associated with the poorer prognosis. Furthermore, the LINC01133 knockdown decreased cyclin G1 (CCNG1) expression. Overexpression of CCNG1 attenuated the LINC01133 silencing-induced impairment of proliferation in PDAC cells. In summary, our findings revealed that the C/EBPbeta-LINC01133 axis performs an oncogenic function in PDAC by activating CCNG1, which may serve as a prognostic biomarker or a therapeutic target in PDAC. PMID- 29458146 TI - Enhanced anticancer effects of Scutellaria barbata D. Don in combination with traditional Chinese medicine components on non-small cell lung cancer cells. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Experience-based herbal medicine as a complementary to modern western medicine has triggered an array of studies in quest of novel anticancer drugs. Scutellaria barbata D. Don (SB) is commonly used to treat different types of cancers, but its molecular mechanism of action is not clearly understood. In this study, we attempted to elucidate the mode of action of a traditional Chinese medicine prescription with a total of 14 components, named Lian-Jia-San-Jie-Fang (LJSJF, in Chinese), where SB works as the "principle" against non-small cell lung cancer (NSCLC) cells. MATERIALS AND METHODS: Four different NSCLC cell lines (A549, H460, H1650, and H1975) were used. Cytotoxicity, in vitro tumorigenicity, gene expression, and protein expression were analyzed by MTT assay, soft agar assay, real-time PCR, and Western blots, respectively. RESULTS: Among the 14 components in LJSJF, SB was the only one to possess cytotoxic effects at its pharmacologically relevant doses. Additionally, we observed synergistically dose-dependent cytotoxic effects of SB in combination with other LJSJF components. After SB or LJSJF treatment, significant reductions in colony number and/or size were observed in A549 and H460; a notable dose-dependent decrease in EGFR was observed in A549, H460, and H1650; significant downregulation in EGFR and its downstream signaling targets mTOR and p38MAPK were also observed in A549 and H460; and p53 and p21 were significantly increased while survivin, cyclin D1, and MDM2 were significantly decreased in A549. Additionally, p53, p21, and Mettl7b were decreased, but p73 was increased in H460. Neither EGFR nor p53 was changed in H1975. Therefore, SB or LJSJF may induce cytotoxic effects by regulating multiple and/or distinct apoptotic pathways in different NSCLC cells. CONCLUSION: LJSJF exerts more pronounced cytotoxic effects against NSCLC cells than SB does by synergistically regulating the underlining molecular mechanisms including EGFR and/or p53 signaling pathways. PMID- 29458147 TI - Sessein and isosessein with anti-inflammatory, antibacterial and antioxidant activity isolated from Salvia sessei Benth. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Salvia sessei Benth, popularly known as "pipilolxochitl" or "sabanito", is a plant utilized in Mexico in traditional medicine for the treatment of erysipela. To date, only one report, to our knowledge, has been found in which a royleanone-type diterpene of the aerial parts of the species was isolated but, again to our knowledge, studies have not been conducted on the pharmacological activity of extracts and compounds isolated from this plant. AIM OF THE STUDY: The objective of the study was to evaluate the anti-inflammatory, antibacterial and antioxidant activity of the organic extracts of the aerial parts of Salvia sessei Benth and sessein and isosessein isomers isolated from this. MATERIALS AND METHODS: Anti-inflammatory activity was evaluated in a model of edema in mouse ear at 1 mg/ear of the isolated extracts and compounds (1 and 2), a dose-response curve was performed on these latter and one-half of the effective dose (ED50) was determined; antibacterial activity was determined through minimal inhibitory concentration (MIC) by microdilution at 100, 50, 25, and 12.5 ug/mL, and antioxidant capacity, by means of DPPH, ABTS, and FRAP assays where, for the first two assays noted, the inhibitory concentration 50% (IC50) was calculated for the extracts as well as for the compounds isolated. RESULTS: The hexanic extracts (40.55 +/- 0.5%), dichloromethanic (56.01 +/- 1.1%) and methanolic (66.05 +/- 0.3%), as well as isolated compounds 1 (79.85 +/- 3.5%) and 2 (54.36 +/- 1.7%), demonstrated anti inflammatory activity; the methanolic extract presented the greatest percentage of inhibition, while isolated compounds 1 and 2 did not present a difference in their ED50; additionally, compound 1 exerted a similar effect to that of the drug of-reference at the same dose (75.24 +/- 2.4%). The antibacterial activity of the extracts and compounds was principally against Gram-positive bacteria: the hexanic extract presented activity against Staphylococcus hominis and the methanolic and dichloromethanic extracts, and compound 1 exhibited activity against Staphylococcus haemolyticus, S. hominis, E. faecalis, in addition to that Escherichia coli was sensitive to compound 1, while isomer 2 showed activity against Staphylococcus aureus, Staphylococcus haemolyticus, Staphylococcus epidermis and Streptococcus pyogenes bacteria related to erysipela. In the three assays, the extract demonstrating greatest antioxidant capacity was the methanolic extract, while that of the isolated compounds was compound 1. CONCLUSIONS: The results show that the three extracts evaluated in the three models presented activity and the chromatographic separation of the dichloromethanic extract permitted the isolation of compounds 1 and 2 royleanone type isomers, which also presented significant activities such as anti inflammatory, antibacterial and antioxidant, thus validate the use of this species in traditional medicine. PMID- 29458148 TI - Untimely oxidative stress in beta-cells leads to diabetes - Role of circadian clock in beta-cell function. AB - Diabetes results from a loss of beta-cell function. With the number of people with diabetes reaching epidemic proportions globally, understanding mechanisms that are contributing to this increasing prevalence is critical. One such factor has been circadian disruption, with shift-work, light pollution, jet-lag, increased screen time, all acting as potential contributory factors. Though circadian disruption has been epidemiologically associated with diabetes and other metabolic disorders for many decades, it is only recently that there has been a better understanding of the underlying molecular mechanisms. Experimental circadian disruption, via manipulation of environmental or genetic factors using gene-deletion mouse models, has demonstrated the importance of circadian rhythms in whole body metabolism. Genetic disruption of core clock genes, specifically in the beta-cells in mice, have, now demonstrated the importance of the intrinsic beta-cell clock in regulating function. Recent work has also shown the interaction of the circadian clock and enhancers in beta-cells, indicating a highly integrated regulation of transcription and cellular function by the circadian clock. Disruption of either the whole body or only the beta-cell clock leads to significant impairment of mitochondrial function, uncoupling, impaired vesicular transport, oxidative stress in beta-cells and finally impaired glucose stimulated insulin secretion and diabetes. In this review, we explore the role of the circadian clock in mitigating oxidative stress and preserving beta-cell function. PMID- 29458149 TI - Age-dependent oxidation of extracellular cysteine/cystine redox state (Eh(Cys/CySS)) in mouse lung fibroblasts is mediated by a decline in Slc7a11 expression. AB - Aging is associated with progressive oxidation of the extracellular environment. The redox state of human plasma, defined by the concentrations of cysteine (Cys) and cystine (CySS), becomes more oxidized as we age. Recently, we showed that fibroblasts isolated from the lungs of young and old mice retain this differential phenotype; old cells produce and maintain a more oxidizing extracellular redox potential (Eh(Cys/CySS)) than young cells. Microarray analysis identified down-regulation of Slc7a11, the light subunit of the CySS/glutamate transporter, as a potential mediator of age-related oxidation in these cells. The purpose of the present study was to investigate the mechanistic link between Slc7a11 expression and extracellular Eh(Cys/CySS). Sulforaphane treatment or overexpression of Slc7a11 was used to increase Slc7a11 in lung fibroblasts from old mice, and sulfasalazine treatment or siRNA-mediated knock down was used to decrease Slc7a11 in young fibroblasts. Slc7a11 mRNA levels were measured by real-time PCR, Slc7a11 activity was determined by measuring the rate of glutamate release, Cys, CySS, glutathione (GSH) and its disulfide (GSSG) were measured by HPLC, and Eh(Cys/CySS) was calculated from the Nernst equation. The results showed that both Eh(Cys/CySS) and Eh(GSH/GSSG) were more oxidized in the conditioned media of old cells than in young cells. Up-regulation of Slc7a11 via overexpression or sulforaphane treatment restored extracellular Eh(Cys/CySS) in cultures of old cells, whereas down-regulation reproduced the oxidizing Eh(Cys/CySS) in young cells. Only sulforaphane treatment was able to increase total GSH and restore Eh(GSH/GSSG), whereas overexpression, knock down and sulfasalazine had no effect on these parameters. In addition, inhibition of GSH synthesis with buthionine sulfoximine had no effect on the ability of cells to restore their extracellular redox potential in response to an oxidative challenge. In conclusion, our study reveals Slc7a11 is the key regulator of age dependent changes in extracellular Eh(Cys/CySS) in primary mouse lung fibroblasts, and its effects are not dependent on GSH synthesis. PMID- 29458150 TI - PINK1 Protects Auditory Hair Cells and Spiral Ganglion Neurons from Cisplatin induced Ototoxicity via Inducing Autophagy and Inhibiting JNK Signaling Pathway. AB - Phosphatase and tensin homologue (PTEN)-induced putative kinase 1 (PINK1) gene encodes a serine/threonine kinase, which acts as a molecular sensor of mitochondrial health necessary for mitochondrial quality control. The present study was designed to examine whether PINK1 expressed in C57BL/6 murine cochlea and HEI-OC1 cells and, if so, to investigate the possible mechanisms underlying the action of PINK1 in cisplatin-induced death of sensory hair cells (HCs) and spiral ganglion neurons (SGNs) in vitro. The expression pattern of PINK1, formation of parkin particles, and autophagy were determined by immunofluorescent staining. The expressions of PINK1, LC3B, cleaved-caspase 3 and p-JNK were measured by Western blotting. The levels of reactive oxygen species (ROS) were evaluated by DCFH-DA and Mito-Sox Red staining. The mitochondrial membrane potential was detected by Tetramethylrhodamine methyl ester perchlorate (TMRM) and Rhodamine 123. Cell viability and apoptosis were examined by CCK8 assay, TUNEL staining and Annexin V Apoptosis Detection Kit, respectively. We found that PINK1 was widely expressed in the cytoplasm in HCs, SGNs, stria vascularis of C57BL/6 cochlea and HEI-OC1 cells and, notably, the expression level in cochlear HCs and SGNs of postnatal day 4 (P4) mice was higher than that in adult mice. Moreover, treatment with 30 MUM cisplatin elicited the formation of ROS, which, in turn, led to PINK1 activation, parkin recruitment, autophagy formation and JNK pathway relevant to apoptosis in HEI-OC1 cells, HCs, and SGNs. Meanwhile, co treatment with ROS scavenger N-acetyl-L-cysteine (NAC) or H2O2 consumer catalase polyethylene glycol (PEG-catalase) inhibited parkin recruitment, alleviated autophagy formation, and mitigated JNK pathway related apoptosis. In addition, PINK1 silencing resulted in a lower level of autophagy, but, a higher mortality in HEI-OC1 cells treated with cisplatin. Taken together, data from this work reveal that PINK1 possesses the protective effect via induction of autophagy and resistance of apoptosis under cisplatin stimulus in sensory HCs and SGNs, implying that PINK1 might serve as an important regulator of cisplatin-elicited ototoxicity. PMID- 29458151 TI - Endoscopic Management of Pancreatobiliary Neoplasms. AB - Endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) are the mainstays of interventional endoscopic practice. EUS occupies a central role in the diagnosis of pancreatobiliary neoplasms and offers a platform for a wide range of direct tumor therapies. Initial steps have demonstrated the feasibility of such applications in animal models and pilot studies. Larger clinical trials and incorporation of EUS-based therapies into cooperative cancer studies might demonstrate an impact in the clinical prognosis of patients with pancreatic cancer. ERCP plays an important role in elucidating indeterminate biliary strictures and in treating patients with malignant biliary obstruction who are symptomatic or have borderline-resectable or unresectable disease. ERCP directed ablative therapies enable neoadjuvant and palliative intervention in patients with malignant biliary obstruction, in particular perihilar cholangiocarcinoma. Additional comparative, multicenter studies are needed to better understand the safety and efficacy of endobiliary brachytherapy, photodynamic therapy, and radiofrequency ablation in patients with pancreatobiliary malignancies. PMID- 29458152 TI - Controversies in Endoscopic Eradication Therapy for Barrett's Esophagus. AB - Advances in endoscopic eradication therapy for Barrett's Esophagus-associated neoplasia have resulted in a significant paradigm shift in the diagnosis and management of this complex disease. A robust body of literature critically evaluating outcomes of resection and ablative strategies has allowed gastroenterologists to make quality, evidence-based decisions for their patients. Despite this progress, there are still many unanswered questions and challenges that remain. Ultimately, identification of a cost-effective screening modality, biomarkers for risk stratification, and strides to eliminate post surveillance endoscopy after endoscopic eradication therapy are essential to reach our long term goal for eradication of esophageal adenocarcinoma. PMID- 29458153 TI - EUS-Guided Transluminal Interventions. AB - The role of endoscopic ultrasound (EUS) has transitioned from a diagnostic to a therapeutic one over the past 40 years. With the advent of curvilinear array echoendoscopes in the 1990s with an accessory channel, multiple tools and devices have been developed and used for a variety of transluminal interventions. EUS provides a viable option and is becoming the procedure of choice for many interventions, including bile and pancreatic duct drainage, guiding angiotherapy, pancreatic fluid collection management, gallbladder drainage, and creating a gastrojejunostomy. Although reports demonstrate the technical success of these interventions, there is tremendous study heterogeneity and a relative lack of controlled randomized trials, which may limit our understanding of their role and utility. Furthermore, adverse events are relatively common and occasionally severe. Despite the limitations, available data strongly indicate the efficacy of EUS interventions when performed by well-trained endosonographers in carefully selected patients and managed in a multidisciplinary setting. PMID- 29458154 TI - The Effect of Endoscopic Surveillance in Patients With Barrett's Esophagus: A Systematic Review and Meta-analysis. AB - BACKGROUND & AIMS: Guidelines recommend endoscopic surveillance of patients with Barrett's esophagus (BE) to identify those with dysplasia (a precursor of carcinoma) or early-stage esophageal adenocarcinoma (EAC) who can be treated endoscopically. However, it is unclear whether surveillance increases survival times of patients with BE. We performed a systematic review and meta-analysis to qualitatively and quantitatively examine evidence for the association of endoscopic surveillance in patients with BE with survival and other outcomes. METHODS: We searched publication databases for studies reporting the effects of endoscopic surveillance on mortality and other EAC-related outcomes. We reviewed randomized controlled trials, case-control studies, studies comparing patients with BE who received regular surveillance with those who did not receive regular surveillance, and studies comparing outcomes of patients with surveillance detected EAC vs symptom-detected EACs. We performed a meta-analysis of surveillance studies to generate summary estimates using a random effects model. The primary aim was to examine the association of BE surveillance on EAC-related mortality. Secondary aims were to examine the association of BE surveillance with all-cause mortality and EAC stage at time of diagnosis. RESULTS: A single case control study did not show any association between surveillance and EAC-related mortality. A meta-analysis of 4 cohort studies found that lower EAC-related and all-cause mortality were associated with regular surveillance (relative risk, 0.60; 95% CI, 0.50-0.71; hazard ratio, 0.75; 95% CI, 0.59-0.94). Meta-analysis of 12 cohort studies showed lower EAC-related and all-cause mortality among patients with surveillance-detected EAC vs symptom-detected EAC (relative risk, 0.73; 95% CI, 0.57-0.94; hazard ratio, 0.59; 95% CI, 0.45-0.76). Lead- and length-time bias adjustment substantially attenuated/eliminated the observed benefits. Surveillance was associated with detection of EAC at earlier stages. A randomized trial is underway to evaluate the effects of endoscopic surveillance on mortality in patients with BE. CONCLUSIONS: In a systematic review and meta-analysis of the effects of surveillance in patients with BE, surveillance as currently performed was associated with detection of earlier-stage EAC and may provide a small survival benefit. However, the effects of confounding biases on these estimates are not fully defined and may completely or partially explain the observed differences between surveyed and unsurveyed patients. PMID- 29458156 TI - How to isolate, identify and determine antimicrobial susceptibility of anaerobic bacteria in routine laboratories. AB - BACKGROUND: There has been increased interest in the study of anaerobic bacteria that cause human infection during the past decade. Many new genera and species have been described using 16S rRNA gene sequencing of clinical isolates obtained from different infection sites with commercially available special culture media to support the growth of anaerobes. Several systems, such as anaerobic pouches, boxes, jars and chambers provide suitable anaerobic culture conditions to isolate even strict anaerobic bacteria successfully from clinical specimens. Beside the classical, time-consuming identification methods and automated biochemical tests, the use of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry has revolutionized identification of even unusual and slow-growing anaerobes directly from culture plates, providing the possibility of providing timely information about anaerobic infections. AIMS: The aim of this review article is to present methods for routine laboratories, which carry out anaerobic diagnostics on different levels. SOURCES: Relevant data from the literature mostly published during the last 7 years are encompassed and discussed. CONTENT: The review involves topics on the anaerobes that are members of the commensal microbiota and their role causing infection, the key requirements for collection and transport of specimens, processing of specimens in the laboratory, incubation techniques, identification and antimicrobial susceptibility testing of anaerobic bacteria. Advantages, drawbacks and specific benefits of the methods are highlighted. IMPLICATIONS: The present review aims to update and improve anaerobic microbiology in laboratories with optimal conditions as well as encourage its routine implementation in laboratories with restricted resources. PMID- 29458157 TI - Clostridium innocuum is a vancomycin-resistant pathogen that may cause antibiotic associated diarrhoea. AB - OBJECTIVES: Clostridium innocuum can cause extraintestinal infection in patients with underlying diseases. The role of C. innocuum in antibiotic-associated diarrhoea (AAD) remains unknown. METHODS: Clinical information of 103 patients from whom C. innocuum was isolated was reviewed. We carried out cellular and animal experiments to examine the pathogenic potential of C. innocuum in AAD. RESULTS: Eighty-eight per cent (91/103) of the 103 patients received antibiotics within 2 weeks of diarrhoea onset. Patients were further classified into two groups, severe colitis and diarrhoea, according to clinical severity level. The mortality rate was 13.6% (14/103) among the patients from whom C. innocuum was isolated. The lowest concentrations at which 90% of the isolates were inhibited for metronidazole and vancomycin were 0.5 and 16 mg/L, respectively. All isolates tested were susceptible to metronidazole but resistant to vancomycin. Nineteen randomly selected isolates (ten from severe colitis group, nine from diarrhoea group) were subjected to further in vitro cellular examinations. The level of cytotoxicity to Vero cells was significantly higher in isolates from the severe colitis group at both 24 and 48 hours after inoculation (24 and 48 hours, p 0.042 and 0.033, respectively). We observed apoptotic changes that subsequently led to cell death in C. innocuum-infected Vero cells. Tissue damages, necrotic changes and oedema were observed in the mouse ileal loop infected by C. innocuum. CONCLUSIONS: Vancomycin-resistant C. innocuum may play a potential role as a causative agent of AAD. The clinical manifestations of AAD caused by C. innocuum were diarrhoea or severe colitis, including pseudomembranous colitis. PMID- 29458155 TI - Determining Risk of Colorectal Cancer and Starting Age of Screening Based on Lifestyle, Environmental, and Genetic Factors. AB - BACKGROUND & AIMS: Guidelines for initiating colorectal cancer (CRC) screening are based on family history but do not consider lifestyle, environmental, or genetic risk factors. We developed models to determine risk of CRC, based on lifestyle and environmental factors and genetic variants, and to identify an optimal age to begin screening. METHODS: We collected data from 9748 CRC cases and 10,590 controls in the Genetics and Epidemiology of Colorectal Cancer Consortium and the Colorectal Transdisciplinary study, from 1992 through 2005. Half of the participants were used to develop the risk determination model and the other half were used to evaluate the discriminatory accuracy (validation set). Models of CRC risk were created based on family history, 19 lifestyle and environmental factors (E-score), and 63 CRC-associated single-nucleotide polymorphisms identified in genome-wide association studies (G-score). We evaluated the discriminatory accuracy of the models by calculating area under the receiver operating characteristic curve values, adjusting for study, age, and endoscopy history for the validation set. We used the models to project the 10 year absolute risk of CRC for a given risk profile and recommend ages to begin screening in comparison to CRC risk for an average individual at 50 years of age, using external population incidence rates for non-Hispanic whites from the Surveillance, Epidemiology, and End Results program registry. RESULTS: In our models, E-score and G-score each determined risk of CRC with greater accuracy than family history. A model that combined both scores and family history estimated CRC risk with an area under the receiver operating characteristic curve value of 0.63 (95% confidence interval, 0.62-0.64) for men and 0.62 (95% confidence interval, 0.61-0.63) for women; area under the receiver operating characteristic curve values based on only family history ranged from 0.53 to 0.54 and those based only E-score or G-score ranged from 0.59 to 0.60. Although screening is recommended to begin at age 50 years for individuals with no family history of CRC, starting ages calculated based on combined E-score and G-score differed by 12 years for men and 14 for women, for individuals with the highest vs the lowest 10% of risk. CONCLUSIONS: We used data from 2 large international consortia to develop CRC risk calculation models that included genetic and environmental factors along with family history. These determine risk of CRC and starting ages for screening with greater accuracy than the family history only model, which is based on the current screening guideline. These scoring systems might serve as a first step toward developing individualized CRC prevention strategies. PMID- 29458158 TI - Toll-like receptor 9 (TLR-9) promotor polymorphisms and gene expression are associated with persistent Staphylococcus aureus nasal carriage. AB - OBJECTIVES: Toll-like receptor (TLR) 9 could have importance in human Staphylococcus aureus immunity, but population-level evidence for this hypothesis is missing. METHODS: We phenotyped S. aureus nasal carriage of 603 volunteers using four consecutive swabs, genotyped TLR9 promotor variants in 106 persistent carriers and 219 noncarriers, measured TLR9-mRNA expression in whole blood after stimulation with viable S. aureus and studied mutual associations of carriage, transcriptional activity and single nucleotide polymorphisms while accounting for sex and hormone contraceptive use (HCU). RESULTS: The -1486 (rs187084) and -1237 (rs5743836) CT haplotype was more common in noncarriers (185/438, 42%) than in carriers (63/212, 30%), with the TT haplotype showing a reverse association (noncarriers, 180/438, 41%; carriers 117/212, 55%) (chi2 p 0.001). Mean TLR9 mRNA expression in whole blood was higher in noncarriers (ratiocarriers/noncarriers 0.63; 95% confidence interval, 0.43-0.92; p 0.017). A duplication of TLR9 transcriptional activity lowered the odds of persistent S. aureus carriage by 37% in the overall group (odds ratio = 0.63; 95% confidence interval, 0.42-0.94; p 0.022) and by 54% in women (odds ratio = 0.46; 95% confidence interval, 0.23 0.90; p 0.023). Promotor haplotype and HCU had a combined effect on TLR9 transcription (interaction model): women in the TT (risk) haplotype/HCU- stratum (baseline) had lower mRNA levels than women in the CT (protective) haplotype/HCU- (ratio 1.92; p 0.055), the CT haplotype/HCU+ (ratio 2.02; p 0.032) and the TT haplotype/HCU+ (ratio 2.59; p < 0.004) strata. No such associations were observed in men. CONCLUSIONS: We provide evidence that TLR9 affects human S. aureus immunity and present potential explanations for differences according to sex in S. aureus colonization and infection. PMID- 29458159 TI - Strawberry extracts efficiently counteract inflammatory stress induced by the endotoxin lipopolysaccharide in Human Dermal Fibroblast. AB - A protracted pro-inflammatory state is the common denominator in the development, progression and complication of the common chronic diseases. Dietary antioxidants represent an efficient tool to counteract this inflammatory state. The aim of the present work was to evaluate the effects of strawberry extracts on inflammation evoked by E. Coli lipopolysaccharide in Human Dermal Fibroblast, by measuring reactive oxygen species production, apoptosis rate, antioxidant enzymes activity, mitochondria functionality and also investigating the molecular pathway involved in inflammatory and antioxidant response. The results demonstrated that strawberry pre-treatment reduced intracellular reactive oxygen species levels, apoptotic rate, improved antioxidant defences and mitochondria functionality in lipopolysaccharide -treated cells. Strawberry exerted these protective activities through the inhibition of the NF-kB signalling pathway and the stimulation of the Nrf2 pathway, with a mechanism AMPK-dependent. These results confirm the health benefits of strawberry in the prevention of inflammation and oxidative stress condition in lipopolysaccharide-treated cells. PMID- 29458160 TI - Gambogic acid sensitizes breast cancer cells to TRAIL-induced apoptosis by promoting the crosstalk of extrinsic and intrinsic apoptotic signalings. AB - Due to the ability of tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) to induce cancer cell apoptosis selectively, TRAIL has attracted significant interest in the treatment of cancer. However, although TRAIL triggers apoptosis in a broad range of cancer cells, most primary cancers are often intrinsically TRAIL-resistant, or can acquire resistance after TRAIL treatment, evocating new strategies to overcome TRAIL resistance. Gambogic acid (GA), an active constituent of Garcinia Hanburyi (Teng Huang in Chinese), has been applied for thousands of years for medicinal uses, however, the potential effect of GA in combating cancer resistance remains poorly investigated. In this study, we found that GA could increase the sensitivity of breast cancer cells to TRAIL and enhance TRAIL-induced apoptosis. GA cooperated with TRAIL to decrease the levels of anti-apoptotic proteins and activate Bid (BH3 interacting-domain death agonist) to promote the crosstalk of extrinsic and intrinsic apoptotic signaling, rather than increasing the expression of TRAIL receptors DR4 and DR5. These findings may open a new window in the treatment of breast cancer using TRAIL in combination with GA. PMID- 29458161 TI - Multiple mycotoxin analysis in nut products: Occurrence and risk characterization. AB - Nuts consumption plays an important role in Mediterranean diet, being a good source of proteins, vitamins, minerals and unsaturated fatty acids. However, nuts can be also a source of harmful mycotoxins with negative impact on human health. In this work, the occurrence of 16 mycotoxins belonging to different chemical classes, was assessed in several nut products. The analytical method used was based on modified QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) procedure followed by liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis. An extensive evaluation of different sorbents used in dispersive SPE (d SPE) cleanup step of QuEChERS was performed. Detection limits achieved were less than 3.5 MUg/kg for all the compounds and the average recoveries varied from 70 to 91%, with relative standard deviations (RSD) <=13%. Twelve out of sixteen mycotoxins under study were found in the 37 nut samples analysed. Overall, deoxynivalenol (DON), aflatoxin-G2 (AFG2), and fusarenon-X (FUS X) were the compounds more commonly detected. The higher contamination value was observed in a cashew sample containing 336.5 MUg/kg of DON. The combination of occurrence and consumption data allowed to assess the exposure and characterize the associated risk of nut products consumption by the Portuguese population.

PMID- 29458163 TI - DNA adduct profiling of in vitro colonic meat digests to map red vs. white meat genotoxicity. AB - The consumption of red meat has been linked to an increased colorectal cancer (CRC) risk. One of the major hypotheses states that heme iron (present in red meat) stimulates the formation of genotoxic N-nitroso compounds (NOCs) and lipid peroxidation products (LPOs). By means of DNA adductomics, chemically induced DNA adduct formation can be mapped in relation to e.g. dietary exposures. In this study, this state-of-the-art methodology was used to investigate alkylation and (lipid per)oxidation induced DNA adduct formation in in vitro red vs. white meat digests. In doing so, 90 alkylation and (lipid per)oxidation induced DNA adduct types could be (tentatively) identified. Overall, 12 NOC- and/or LPO-related DNA adduct types, i.e. dimethyl-T (or ethyl-T), hydroxymethyl-T, tetramethyl-T, methylguanine (MeG), guanidinohydantoin, hydroxybutyl-C, hydroxymethylhydantoin, malondialdehyde-x3-C, O6-carboxymethylguanine, hydroxyethyl-T, carboxyethyl-T and 3,N4-etheno-C were singled out as potential heme-rich meat digestion markers. The retrieval of these DNA adduct markers is in support of the heme, NOC and LPO hypotheses, suggesting that DNA adduct formation may indeed contribute to red meat related CRC risk. PMID- 29458164 TI - Structure-dependent induction of apoptosis by hepatotoxic pyrrolizidine alkaloids in the human hepatoma cell line HepaRG: Single versus repeated exposure. AB - Pyrrolizidine alkaloids (PA) are secondary plant compounds. PA intoxication in humans causes severe acute and chronic hepatotoxicity. However, the molecular mechanisms of PA hepatotoxicity in humans are not well understood yet. Therefore, we investigated cell death parameters in human HepaRG cells following either single (24 h) or repeated dose treatment (14 d) with structurally different PA of the retronecine (echimidine, senecionine), heliotridine (heliotrine), and otonecine type (senkirkine). After 24 h of exposure only retronecine-type PA were cytotoxic in HepaRG cells and induced apoptosis indicated by a loss of membrane asymmetry, disruption of the mitochondrial membrane potential, and increased pro caspase and PARP cleavage. In contrast, after 14 d all four PA exerted the aforementioned effects. Furthermore, the apoptotic events caspase 3, 8 and 9 activation as well as nuclear condensation and DNA fragmentation were only detected for the retronecine-type PA after single exposure (6 h). Overall, our studies revealed a time- and structure-dependent apoptosis after PA exposure, suggesting that retronecine-type PA seem to be more potent apoptosis inducers than heliotridine- or otonecine-type PA. Furthermore, our results suggest that PA induced apoptosis in HepaRG cells occur most probably by involving both, the extrinsic death receptor pathway as well as the intrinsic mitochondrial pathway. PMID- 29458165 TI - A microbial identification framework for risk assessment. AB - Micro-organisms are increasingly used in a variety of products for commercial uses, including cleaning products. Such microbial-based cleaning products (MBCP) are represented as a more environmentally-friendly alternative to chemically based cleaning products. The identity of the micro-organisms formulated into these products is often considered confidential business information and is not revealed or it is only partly revealed (i.e., identification to the genus, not to the species). That paucity of information complicates the evaluation of the risk associated with their use. The accurate taxonomic identification of those micro organisms is important so that a suitable risk assessment of the products can be conducted. To alleviate difficulties associated with adequate identification of micro-organisms in MBCP and other products containing micro-organisms, a microbial identification framework for risk assessment (MIFRA) has been elaborated. It serves to provide guidance on a polyphasic tiered approach, combining the data obtained from the use of various methods (i.e., polyphasic approach) combined with the sequential selection of the methods (i.e., tiered) to achieve a satisfactory identity of the micro-organism to an acceptable taxonomic level. The MIFRA is suitable in various risk assessment contexts for micro organisms used in any commercial product. PMID- 29458166 TI - Statistical approach for selection of biologically informative genes. AB - Selection of informative genes from high dimensional gene expression data has emerged as an important research area in genomics. Many gene selection techniques have been proposed so far are either based on relevancy or redundancy measure. Further, the performance of these techniques has been adjudged through post selection classification accuracy computed through a classifier using the selected genes. This performance metric may be statistically sound but may not be biologically relevant. A statistical approach, i.e. Boot-MRMR, was proposed based on a composite measure of maximum relevance and minimum redundancy, which is both statistically sound and biologically relevant for informative gene selection. For comparative evaluation of the proposed approach, we developed two biological sufficient criteria, i.e. Gene Set Enrichment with QTL (GSEQ) and biological similarity score based on Gene Ontology (GO). Further, a systematic and rigorous evaluation of the proposed technique with 12 existing gene selection techniques was carried out using five gene expression datasets. This evaluation was based on a broad spectrum of statistically sound (e.g. subject classification) and biological relevant (based on QTL and GO) criteria under a multiple criteria decision-making framework. The performance analysis showed that the proposed technique selects informative genes which are more biologically relevant. The proposed technique is also found to be quite competitive with the existing techniques with respect to subject classification and computational time. Our results also showed that under the multiple criteria decision-making setup, the proposed technique is best for informative gene selection over the available alternatives. Based on the proposed approach, an R Package, i.e. BootMRMR has been developed and available at https://cran.r-project.org/web/packages/BootMRMR. This study will provide a practical guide to select statistical techniques for selecting informative genes from high dimensional expression data for breeding and system biology studies. PMID- 29458167 TI - Autosomal dominant deficiency of the interleukin-17F in recurrent aphthous stomatitis: Possible novel mutation in a new entity. AB - Recurrent Aphthous Stomatitis (RAS) is a common oral inflammatory disease with unknown pathogenesis. Although the immune system alterations could be involved in predisposition of individuals to oral candidiasis, precise etiologies of RAS have not been understood yet. A recent study showed that autosomal dominant IL17F deficiency could cause chronic mucocutaneous candidiasis. Considering the inflammatory nature of interleukin (IL)-17F and RAS, this study was performed to check any disease-associated mutation in a number of patients with RAS. Sixty-two Iranian individuals with RAS were investigated in this study. After DNA extraction using a phenol-chloroform method from the whole blood, amplification was accomplished by polymerase chain reaction and the products were sequenced using a 3730 ABI sequencer. The results of sequencing revealed a missense, heterozygous mutation of IL17F, converting a threonine to proline in a patient with RAS (T79P). The Poly-phen software suggested a damaging probability predicting this substitution to have a harmful effect on IL-17F protein function. This mutation was checked in fifty healthy individuals, and was not detected in any of them. This is the first study showing that a mutation in IL-17F is associated with susceptibility to RAS. However, functional studies and further studies on more patients with RAS are required to confirm such association. PMID- 29458169 TI - Inhibition of microsomal prostaglandin E synthase-1 facilitates liver repair after hepatic injury in mice. AB - BACKGROUND & AIMS: Liver repair following hepatic ischemia/reperfusion (I/R) injury is crucial to survival. This study aims to examine the role of endogenous prostaglandin E2 (PGE2) produced by inducible microsomal PGE synthase-1 (mPGES 1), a terminal enzyme of PGE2 generation, in liver injury and repair following hepatic I/R. METHODS: mPGES-1 deficient (Ptges-/-) mice or their wild-type (WT) counterparts were subjected to partial hepatic ischemia followed by reperfusion. The role of E prostanoid receptor 4 (EP4) was then studied using a genetic knockout model and a selective antagonist. RESULTS: Compared with WT mice, Ptges /- mice exhibited reductions in alanine aminotransferase (ALT), necrotic area, neutrophil infiltration, chemokines, and proinflammatory cytokine levels. Ptges-/ mice also showed promoted liver repair and increased Ly6Clow macrophages (Ly6Clow/CD11bhigh/F4/80high-cells) with expression of anti-inflammatory and reparative genes, while WT mice exhibited delayed liver repair and increased Ly6Chigh macrophages (Ly6Chigh/CD11bhigh/F4/80low-cells) with expression of proinflammatory genes. Bone marrow (BM)-derived mPGES-1-deficient macrophages facilitated liver repair with increases in Ly6Clow macrophages. In vitro, mPGES-1 was expressed in macrophages polarized toward the proinflammatory profile. Mice treated with the mPGES-1 inhibitor Compound III displayed increased liver protection and repair. Hepatic I/R enhanced the hepatic expression of PGE receptor subtype, EP4, in WT mice, which was reduced in Ptges-/- mice. A selective EP4 antagonist and genetic deletion of Ptger4, which codes for EP4, accelerated liver repair. The proinflammatory gene expression was upregulated by stimulation of EP4 agonist in WT macrophages but not in EP4-deficient macrophages. CONCLUSIONS: These results indicate that mPGES-1 regulates macrophage polarization as well as liver protection and repair through EP4 signaling during hepatic I/R. Inhibition of mPGES-1 could have therapeutic potential by promoting liver repair after acute liver injury. LAY SUMMARY: Hepatic ischemia/reperfusion injury is a serious complication that occurs in liver surgery. Herein, we demonstrated that inducible prostaglandin E2 synthase (mPGES-1), an enzyme involved in synthesizing prostaglandin E2, worsens the injury and delays liver repair through accumulation of proinflammatory macrophages. Inhibition of mPGES-1 offers a potential therapy for both liver protection and repair in hepatic ischemia/reperfusion injury. PMID- 29458168 TI - Apoptosis of enterocytes and nitration of junctional complex proteins promote alcohol-induced gut leakiness and liver injury. AB - BACKGROUND & AIMS: Binge alcohol exposure causes gut leakiness, contributing to increased endotoxemia and inflammatory liver injury, although the molecular mechanisms are still elusive. This study was aimed at investigating the roles of apoptosis of enterocytes and nitration followed by degradation of intestinal tight junction (TJ) and adherens junction (AJ) proteins in binge alcohol-induced gut leakiness. METHODS: The levels of intestinal (ileum) junctional complex proteins, oxidative stress markers and apoptosis-related proteins in rodents, T84 colonic cells and autopsied human ileums were determined by immunoblot, immunoprecipitation, immunofluorescence, and mass-spectral analyses. RESULTS: Binge alcohol exposure caused apoptosis of gut enterocytes with elevated serum endotoxin and liver injury. The levels of intestinal CYP2E1, iNOS, nitrated proteins and apoptosis-related marker proteins were significantly elevated in binge alcohol-exposed rodents. Differential, quantitative mass-spectral analyses of the TJ-enriched fractions of intestinal epithelial layers revealed that several TJ, AJ and desmosome proteins were decreased in binge alcohol-exposed rats compared to controls. Consistently, the levels of TJ proteins (claudin-1, claudin-4, occludin and zonula occludens-1), AJ proteins (beta-catenin and E cadherin) and desmosome plakoglobin were very low in binge alcohol-exposed rats, wild-type mice, and autopsied human ileums but not in Cyp2e1-null mice. Additionally, pretreatment with specific inhibitors of CYP2E1 and iNOS prevented disorganization and/or degradation of TJ proteins in alcohol-exposed T84 colonic cells. Furthermore, immunoprecipitation followed by immunoblot confirmed that intestinal TJ and AJ proteins were nitrated and degraded via ubiquitin-dependent proteolysis, resulting in their decreased levels. CONCLUSIONS: These results demonstrated for the first time the critical roles of CYP2E1, apoptosis of enterocytes, and nitration followed by ubiquitin-dependent proteolytic degradation of the junctional complex proteins, in promoting binge alcohol induced gut leakiness and endotoxemia, contributing to inflammatory liver disease. LAY SUMMARY: Binge alcohol exposure causes gut leakiness, contributing to increased endotoxemia and inflammatory liver injury. Our results demonstrated for the first time the critical roles of apoptosis of enterocytes and nitration followed by ubiquitin-dependent proteolytic degradation of the junctional complex proteins in promoting this gut leakiness and endotoxemia. These results provide insight into the molecular mechanisms of alcohol-induced inflammatory liver disease. PMID- 29458170 TI - Downregulation of metabotropic glutamate receptor 5 inhibits hepatoma development in a neurotoxin rotenone-induced Parkinson's disease model. AB - Clinical epidemiological studies have shown that there is a link between Parkinson's disease (PD) and cancer, but how PD regulates cancer development remains unknown. In our study, the effect of metabotropic glutamate receptor 5 (mGlu5) on hepatoma was explored in a rotenone-induced PD model both in vitro and in vivo. We found that conditioned media derived from MN9D dopaminergic neuronal cells by rotenone-induced toxicity inhibited the growth, migration, invasion and promoted apoptosis of Hepa1-6 cells, which corresponded with decreased expression of mGlu5. Furthermore, treatment with 2-methyl-6-(phenylethynyl)pyridine (MPEP), a mGlu5 antagonist and knockdown of mGlu5, further reduced ATP levels and migration distance, and increased cleavage of caspase-3 in Hepa1-6 cells. Additionally, we found that conditioned media derived from rotenone-treated MN9D dopaminergic neuronal cells enhanced reactive oxygen species (ROS) generation and JNK phosphorylation, which could be further increased by MPEP treatment, and attenuated by mGlu5 agonist, (RS)-2-Chloro-5-hydroxyphenylglycine (CHPG) and ROS scavenger, N-acetyl-l-cysteine (NAC). The results indicated that down-regulation of mGlu5 promoted cell apoptosis through the intracellular ROS/JNK signaling pathway in a rotenone-induced cellular PD model. These findings were confirmed in vivo in a rotenone-induced rat model of PD combined with diethylnitrosamine (DEN) induced hepatoma. Expression of Ki67 was decreased, and the levels of caspase-3 and p-JNK were increased in this model, which was accompanied by a decrease in protein expression of mGlu5. The study suggest that negative regulation of mGlu5 may inhibit hepatoma development in a rotenone-induced PD model, and as such may help with our further understanding of the correlation between PD and cancer. PMID- 29458171 TI - Toxicology studies of furosine in vitro/in vivo and exploration of the related mechanism. AB - AIM: Furosine is one of the Maillard reaction products (MRPs) and is found in a variety of heat-processed food. Yet its toxicity is still unclear. The present study was designed to assess furosine toxicity in cell models and in CD-1 mice, respectively. METHODS: In vitro, the effects of furosine on the cell viability, cell cycle and apoptosis (Hek293, HepG2, SK-N-SH and Caco2) were detected and evaluated, sensitive cell lines and proper dosage of furosine for further animal experiment were determined, and the mechanisms of toxicity were explored. In vivo, the acute toxicity studieswere performed, organ index, hematology parameters, functions of liver/kidney and pathological changes were detected and the target organs were uncovered. RESULTS: Hek293 cells and HepG2 cells were themost sensitive to furosine with respect to cytotoxicity and apoptosis. Furosine inhibited mice weight gain, and affected the functions of liver and kidney. CONCLUSIONS: Furosine posed toxic effects on mice liver and kidney, suggested thatthey were the target organs for furosine toxicity. This study for the first time provides evidence that high dosages of furosine pose adverse biological effects on the health of animals through induction of cell apoptosis and activation of inflammatory necrosis response.

AB - Cell transplantation has been challenged in several clinical indications of genetic or acquired muscular diseases, but therapeutic success were mitigated. To understand and improve the yields of tissue regeneration, we aimed at modelling the fate of CD56-positive human myoblasts after transplantation. Using immunodeficient severe combined immunodeficiency (SCID) mice as recipients, we assessed the survival, integration and satellite cell niche occupancy of human myoblasts by a triple immunohistochemical labelling of laminin, dystrophin and human lamin A/C. The counts were integrated into a classical mathematical decline equation. After injection, human cells were essentially located in the endomysium, then they disappeared progressively from D0 to D28. The final number of integrated human nuclei was grossly determined at D2 after injection, suggesting that no more efficient fusion between donor myoblasts and host fibers occurs after the resolution of the local damages created by needle insertion. Almost 1% of implanted human cells occupied a satellite-like cell niche. Our mathematical model validated by histological counting provided a reliable quantitative estimate of human myoblast survival and/or incorporation into SCID muscle fibers. Informations brought by histological labelling and this mathematical model are complementary. PMID- 29458173 TI - Deregulation of Nrf2/ARE signaling pathway causes susceptibility of dystrophin deficient myotubes to menadione-induced oxidative stress. AB - Duchenne muscular dystrophy (DMD) is an X chromosome-linked disorder caused by a mutation in the dystrophin gene. Many previous studies reported that the skeletal muscles of DMD patients were more susceptible to oxidative stress than those of healthy people. However, not much has been known about the responsible mechanism of the differential susceptibility. In this study, we established dystrophin knock-down (DysKD) cell lines by transfection of dystrophin shRNA lentiviral particles into C2 cells and found that DysKD myotubes are more vulnerable to menadione-induced oxidative stress than control myotubes. We focused on the nuclear erythroid 2-related factor 2 (Nrf2) which is a transcription factor that regulates the expression of phase II antioxidant enzymes by binding to the antioxidant response element (ARE). Under menadione-induced oxidative stress, the translocation of Nrf2 to the nucleus is significantly decreased in the DysKD myotubes. In addition, the binding of Nrf2 to ARE site of Bcl-2 gene as well as protein expression of Bcl-2 is decreased compared to the control cells. Interestingly, sulforaphane increased Akt activation and Nrf2 translocation to the nucleus in the DysKD myotubes. These results suggest that the Nrf2 pathway might be the responsible pathway to the oxidative stress-induced muscle damage in DMD. PMID- 29458175 TI - Maintenance of hematopoietic stem and progenitor cells in fetal intra-aortic hematopoietic clusters by the Sox17-Notch1-Hes1 axis. AB - The aorta-gonad-mesonephros region, from which definitive hematopoiesis first arises in midgestation mouse embryos, has intra-aortic hematopoietic clusters (IAHCs) containing hematopoietic stem cells (HSCs) and hematopoietic progenitor cells (HPCs). We previously reported expression of the transcription factor Sox17 in IAHCs, and overexpression of Sox17 in CD45lowc-KIThigh cells comprising IAHCs maintains the formation of cell clusters and their multipotency in vitro over multiple passages. Here, we demonstrate the importance of NOTCH1 in IAHC formation and maintenance of the HSC/HPC phenotype. We further show that Notch1 expression is positively regulated by SOX17 via direct binding to its gene promoter. SOX17 and NOTCH1 were both found to be expressed in vivo in cells of IAHCs by whole mount immunostaining. We found that cells transduced with the active form of NOTCH1 or its downstream target, Hes1, maintained their multipotent colony-forming capacity in semisolid medium. Moreover, cells stimulated by NOTCH1 ligand, Jagged1, or Delta-like protein 1, had the capacity to form multilineage colonies. Conversely, knockdown of Notch1 and Hes1 led to a reduction of their multipotent colony-forming capacity. These results suggest that the Sox17-Notch1-Hes1 pathway is critical for maintaining the undifferentiated state of IAHCs. PMID- 29458174 TI - Networks that link cytoskeletal regulators and diaphragm proteins underpin filtration function in Drosophila nephrocytes. AB - Insect nephrocytes provide a valuable model for kidney disease, as they are structurally and functionally homologous to mammalian kidney podocytes. They possess an exceptional macromolecular assembly, the nephrocyte diaphragm (ND), which serves as a filtration barrier and helps maintain tissue homeostasis by filtering out wastes and toxic products. However, the elements that maintain nephrocyte architecture and the ND are not understood. We show that Drosophila nephrocytes have a unique cytoplasmic cluster of F-actin, which is maintained by the microtubule cytoskeleton and Rho-GTPases. A balance of Rac1 and Cdc42 activity as well as proper microtubule organization and endoplasmic reticulum structure, are required to position the actin cluster. Further, ND proteins Sns and Duf also localize to this cluster and regulate organization of the actin and microtubule cytoskeleton. Perturbation of any of these inter-dependent components impairs nephrocyte ultrafiltration. Thus cytoskeletal components, Rho-GTPases and ND proteins work in concert to maintain the specialized nephrocyte architecture and function. PMID- 29458176 TI - GRP78 Promotes Hepatocellular Carcinoma proliferation by increasing FAT10 expression through the NF-kappaB pathway. AB - Glucose-regulated protein 78(GRP78) and the ubiquitin-like protein FAT10 each promote proliferation in hepatocellular carcinoma(HCC). However, the relationship of GRP78 and FAT10 in HCC proliferation are still not known. In this study, we found that GRP78 and FAT10 were significantly overexpressed in HCC tissues compare with adjacent non-cancerous tissues, and a positive correlation was found between their expression and associated proliferation characteristics. High expression of GRP78 and FAT10 were positively correlated with tumor proliferation and poor prognosis in HCC. Moreover, GRP78 knockdown reduced FAT10 expression and suppressed HCC proliferation in vitro and in vivo. The effects of GRP78 knockdown were rescued by FAT10 up-regulation, whereas FAT10 knockdown reduced HCC proliferation enhanced by GRP78 up-regulation. Furthermore, GRP78 modulated FAT10 expression by regulating the NF-kappaB pathway, direct activation of the NF kappaB pathway increased the expression of FAT10, a gene counteracting the tumor suppressor p53. Taken together, these results suggest that this newly identified GRP78-NF-kappaB-FAT10 axis will provide novel insight into the understanding of the regulatory mechanisms of proliferation in human HCC. PMID- 29458177 TI - Colorimetric detection of microRNA based on DNAzyme and nuclease-assisted catalytic hairpin assembly signal amplification. AB - Accurate and quantitative analysis of microRNA (miRNA) expression is critical for the diagnostics and theranostics of a disease. Herein, a proof-of-concept of a colorimetric horseradish peroxidase-mimicking DNAzyme (HRP-DNAzyme) biosensor for miRNA assay based on nuclease-assisted catalytic hairpin assembly (CHA) signal amplification was demonstrated. Duplex-specific nuclease (DSN) was employed to cleave the single-stranded DNA (ssDNA) chimeric probe (CP) on the magnetic bead (MB) surface via hybridization of the CP and target miRNA. The regenerated miRNA can cleave a large number of ssDNA CP to produce CHA initiator sequence fragments. The CP consists of two main regions: a target miRNA recognition DNA sequence at the 5' end and a CHA initiator (CI) sequence at the 3' end. The catalyzed assembly process of CHA produces a large amount of G-rich DNA. In the presence of hemin, the G-rich DNA forms G-quadruplex/hemin complex and mimics the horseradish peroxidase activity, which catalyzes a colorimetric reaction. For the proof-of-concept, microRNA-21 (miR-21) was selected as the model target to authenticate this strategy as a versatile assay platform. The proposed strategy allowed quantitation of the sequence specificity of miRNA-21 with a detection limit of 9.2 fM in a dynamic range from 10 fM-1 nM, with an excellent ability to discriminate the differences in miRNAs. Additionally, the miRNA assay in real samples was satisfactory, thereby confirming its applicability. Therefore, this method exhibited a great potential as a miRNA quantification method in biomedical research and clinical diagnosis.

PMID- 29458180 TI - Feature-guided attentional capture cannot be prevented by spatial filtering. AB - Feature-based control processes guide attention towards objects with target features in visual search. While these processes are assumed to operate globally across the entire visual field, it remains controversial whether target-matching objects at task-irrelevant locations can be excluded from attentional selection, especially when spatial attention is already narrowly focused elsewhere. We investigated whether probe stimuli at irrelevant lateral locations capture attention when they precede search displays where targets are defined either by a specific feature (colour or orientation) or by a colour/orientation conjunction by measuring N2pc components (an electrophysiological marker of attentional target selection) to these probes. Reliable N2pcs were triggered by probes not only in the feature search tasks but also when participants searched for feature conjunctions, in spite of the fact that conjunction search requires focal spatial attention. Analogous N2pc results were found in the absence of any spatial uncertainty about the location of conjunctively defined targets, which always appeared at fixation. These results show that rapid attentional capture by objects with target-matching features cannot be prevented by top-down spatial filtering mechanisms, and confirm that feature-based attentional guidance processes operate in a spatially global fashion. PMID- 29458181 TI - Hospitalization burden associated with malignant neoplasia and in situ carcinoma in vulva and vagina during a 5-year period (2009-2013) in Spain: An epidemiological study. AB - BACKGROUND: Vulvar and vaginal cancers are considered rare cancers in women. Human Papillomavirus is responsible for 30-76% of them. The aim of this study was to describe the burden of hospital admissions by malignant neoplasia (MN) and in situ carcinoma (ISC) of vulva and vagina from 2009 to 2013, in Spain METHODS: This observational, descriptive study used discharge information obtained from the national surveillance system for hospital data, Conjunto Minimo Basico de Datos, CMBD, provided by the Ministry of Health. RESULTS: From 2009-2013, we found 9,896 hospitalizations coded as MN or ISC of vulva and vagina. Mean age of hospitalization was 69.94 +/- 15.16 years; average length of hospital stay (ALOS) was 10.02 +/- 12.40 days, and mean hospitalization costs were 5,140.31 +/- 3,220.61 euros. Mean hospitalization rate was 9.874 per 100,000 women aged >14 years old (95% CI: 9.689-10.058); mean mortality rate was 0.932 per 100,000 women aged >14 years old (95% CI: 0.872-0.991) and mean case fatality rate was 9.438% (95% CI: 8.862-10.014). CONCLUSION: MN and ISC of vulva and vagina are responsible for a considerable hospitalization burden. Information about these hospitalizations could be useful for cost effectiveness analysis and monitoring of HPV vaccination effectiveness. PMID- 29458182 TI - A direct gateway into the extracellular space: Unconventional secretion of FGF2 through self-sustained plasma membrane pores. AB - As illustrated by a diverse set of examples in this special issue, multiple mechanisms of protein secretion have been identified in eukaryotes that do not involve the endoplasmic reticulum (ER) and the Golgi apparatus. Here we focus on the type I pathway with Fibroblast Growth Factor 2 (FGF2) being the most prominent example. Unconventional secretion of FGF2 from cells is mediated by direct protein translocation across the plasma membrane. A unique feature of this process is the ability of FGF2 to form its own membrane translocation intermediate through oligomerization and membrane insertion. This process depends on the phosphoinositide PI(4,5)P2 at the inner leaflet and results in the formation of lipidic membrane pores in the plasma membrane. Various lines of evidence suggest that these pores are characterized by a toroidal architecture with FGF2 oligomers being accommodated in the center of these structures. At the outer leaflet of the plasma membrane, membrane proximal heparan sulfate proteoglycans are required for the final step of FGF2 translocation into the extracellular space. Based upon mutually exclusive interactions of FGF2 with PI(4,5)P2 versus heparan sulfates, an assembly/disassembly pathway has been proposed to be the underlying principle of directional transport of FGF2 across the plasma membrane. Thus, the core mechanism of unconventional secretion of FGF2 is based upon three discrete steps with (i) PI(4,5)P2 dependent oligomerization of FGF2 at the inner leaflet, (ii) insertion of membrane spanning FGF2 oligomers into the plasma membrane and (iii) disassembly at the outer leaflet mediated by heparan sulfates that subsequently retain FGF2 on cell surfaces. This process has recently been reconstituted with an inside-out membrane model system using giant unilamellar vesicles providing a compelling explanation of how FGF2 reaches the extracellular space in an ER/Golgi independent manner. This review is part of a Special Issue of SCDB on "unconventional protein secretion" edited by Walter Nickel and Catherine Rabouille. PMID- 29458183 TI - Age-Dependent Attitudes of Ischemic Patients Toward Disability After Decompressive Hemicraniectomy for Malignant Middle Cerebral Artery Infarction. AB - OBJECTIVE: To investigate patient attitudes toward acceptable levels of disability after decompressive surgery for malignant middle cerebral artery infarction, including impact of patient age, to improve process of surgical informed consent. METHODS: Patients who had experienced a recent minor stroke were asked to complete a questionnaire containing 2 parts: demographic information, including patient age, sex, years of education, working status, religion, and economic status, and acceptable level of disability based on modified Rankin Scale (mRS) with corresponding illustrations to explain mRS levels. RESULTS: Patient age was identified as an independent determinant of the worst acceptable mRS score with a negative correlation. For nondominant hemispheric malignant infarction, the worst acceptable mRS score was significantly lower (mean +/- SD 2.0 +/- 1.3) for the oldest patients (>70 years old) compared with patients <60 years old (mean +/- SD 3.0 +/- 0.6) and 60-70 years old (mean +/- SD 3.0 +/- 0.8). For dominant hemispheric malignant infarction with language impairment, all age groups showed a significantly lower value for worst acceptable mRS score (mean +/- SD 1.8 +/- 1.1 for patients <60 years old, 1.8 +/- 1.2 for patients 60-70 years old, and 1.0 +/- 1.4 for patients >70 years old). CONCLUSIONS: Patients showed different attitudes toward disability according to their age. Patients >70 years old showed the lowest worst acceptable mRS score after surgical treatment of malignant infarction. Language impairment with dominant hemispheric infarction further decreased the worst acceptable mRS score.

PMID- 29458185 TI - Tiny Cerebral Aneurysms Can Be Treated Safely and Effectively with Low-Profile Visualized Intraluminal Support Stent-Assisted Coiling or Coiling Alone. AB - BACKGROUND: The effectiveness and safety of LVIS stent-coiling is currently not known for treating tiny intracranial aneurysms. OBJECTIVE: To investigate the effectiveness and safety of Low-profile visualized intraluminal support (LVIS) stent-assisted coiling and coiling alone in treating patients with mostly ruptured tiny aneurysms. METHODS: Seventy-five patients with tiny intracranial aneurysms, including 63 ruptured ones, were treated endovascularly and analyzed. RESULTS: In the coiling group, complete occlusion was achieved in 35 patients (83.6%)-nearly complete in 4 patients (9.5%) and noncomplete in 3 patients (7.1%). Intraprocedural rerupture occurred in 2 patients (4.8%), and coil protrusion occurred in 1 patient, with a complication rate of 7.1%. Clinical follow-up at 6-12 months revealed a modified Rankin Scale (mRS) score of 0-1 in 41 patients and 3 in 1 patient. In the stent-assisted group, occlusion was complete in 12 patients (36.4%), nearly complete in 15 patients (45.5%), and noncomplete in 6 patients (18.1%). Six stents (18.2%) did not have good adherence to the wall, with thrombus formation in 3 stents (9.1%). Follow-up angiography in 27 patients at 3-6 months showed no dislocation of the stents, complete occlusion in 24 patients (88.9%), and nearly complete occlusion in the other 3 patients. At 6 months, the mRS score was 0 in 30 patients and 2 in 3 patients. No significant (P > 0.05) differences existed between the 2 groups. CONCLUSION: Tiny cerebral aneurysms can be safely and effectively treated with appropriate endovascular approaches based on aneurysm specific morphology, especially neck size and neck to-dome ratio.

PMID- 29458188 TI - Robust is not necessarily reliable: From within-subjects fMRI contrasts to between-subjects comparisons. AB - Advances in cognitive and affective neuroscience come largely from within subjects comparisons, in which the functional significance of neural activity is determined by contrasting two or more experimental conditions. Clinical and social neuroscience studies have attempted to leverage between-subject variability in such condition differences to better understand psychopathology and other individual differences. Shifting from within-to between-subjects comparisons requires that measures have adequate internal consistency to function as individual difference variables. This is particularly relevant for difference scores-which have lower reliability. The field has assumed reasonable internal consistency of neural measures based on consistent findings across studies (i.e., if a within-subject difference in neural activity is robust, then it must be reliable). Using one of the most common fMRI paradigms in the clinical neuroscience literature (i.e., a face- and shape-matching task), in a large sample of adolescents (N = 139) we replicate a robust finding: amygdala activation is greater for faces than shapes. Moreover, we demonstrate that the internal consistency of the amygdala in face and shape blocks was excellent (Spearman-Brown corrected reliability [SB] > .94). However, the internal consistency of the activation difference between faces and shapes was nearly zero (SB = -.06). This reflected the fact that the amygdala response to faces and shapes was highly correlated (r = .97) across individuals. Increased neural activation to faces versus shapes could not possibly function as an individual difference measure in these data-illustrating how neural activation can be robust within subjects, but unreliable as an individual difference measure. Strong and reproducible condition differences in neural activity are not necessarily well suited for individual differences research-and neuroimaging studies should always report the internal consistency of, and correlations between, activations used in individual differences research. PMID- 29458189 TI - Impact of time-of-day on diffusivity measures of brain tissue derived from diffusion tensor imaging. AB - Diurnal fluctuations in MRI measures of structural and functional properties of the brain have been reported recently. These fluctuations may have a physiological origin, since they have been detected using different MRI modalities, and cannot be explained by factors that are typically known to confound MRI measures. While preliminary evidence suggests that measures of structural properties of the brain based on diffusion tensor imaging (DTI) fluctuate as a function of time-of-day (TOD), the underlying mechanism has not been investigated. Here, we used a longitudinal within-subjects design to investigate the impact of time-of-day on DTI measures. In addition to using the conventional monoexponential tensor model to assess TOD-related fluctuations, we used a dual compartment tensor model that allowed us to directly assess if any change in DTI measures is due to an increase in CSF/free-water volume fraction or due to an increase in water diffusivity within the parenchyma. Our results show that Trace or mean diffusivity, as measured using the conventional monoexponential tensor model tends to increase systematically from morning to afternoon scans at the interface of grey matter/CSF, most prominently in the major fissures and the sulci of the brain. Interestingly, in a recent study of the glymphatic system, these same regions were found to show late enhancement after intrathecal injection of a CSF contrast agent. The increase in Trace also impacts DTI measures of diffusivity such as radial and axial diffusivity, but does not affect fractional anisotropy. The dual compartment analysis revealed that the increase in diffusivity measures from PM to AM was driven by an increase in the volume fraction of CSF-like free-water. Taken together, our findings provide important insight into the likely physiological origins of diurnal fluctuations in MRI measurements of structural properties of the brain. PMID- 29458190 TI - Cannabinoids prevent depressive-like symptoms and alterations in BDNF expression in a rat model of PTSD. AB - Posttraumatic stress disorder (PTSD) is a debilitating condition highly comorbid with depression. The endocannabinoid (eCB) system and brain-derived neurotrophic factor (BDNF) are suggestively involved in both disorders. We examined whether cannabinoids can prevent the long-term depressive-like symptoms induced by exposure to the shock and situational reminders (SRs) model of PTSD. The CB1/2 receptor agonist WIN55,212-2 (0.5 mg/kg; i.p.), the fatty acid hydrolase (FAAH) inhibitor URB597 (0.3 mg/kg, i.p.) or vehicle were administered 2 h after severe shock. Cannabinoids prevented the shock/SRs-induced alterations in social recognition memory, locomotion, passive coping, anxiety-like behavior, anhedonia, fear retrieval, fear extinction and startle response as well as the decrease in BDNF levels in the hippocampus and prefrontal cortex (PFC). Furthermore, significant correlations were found between depressive-like behaviors and BDNF levels in the brain. The findings suggest that cannabinoids may prevent both depressive- and PTSD-like symptoms following exposure to severe stress and that alterations in BDNF levels in the brains' fear circuit are involved in these effects. PMID- 29458191 TI - A novel neuropilin-1-binding sequence in the human T-cell lymphotropic virus type 1 envelope glycoprotein. AB - Entry of human T-cell lymphotropic virus type 1 (HTLV-1) into host cells is mainly mediated by interactions between the viral envelope glycoprotein surface unit (SU) and three host receptors: glucose transporter type 1, heparin/heparan sulfate proteoglycan, and neuropilin-1 (Nrp1). Here, we analyzed the interaction between HTLV-1 SU and Nrp1 using nuclear magnetic resonance and isothermal titration calorimetry. We found that two SU peptides, residues 85-94 and residues 304-312, bound directly to the Nrp1 b1 domain with affinities of 7.4 and 17.7 MUM, respectively. The binding modes of both peptides were almost identical to those observed for Tuftsin and vascular endothelial growth factor A binding to the Nrp1 b1 domain. These results suggest that the C-terminal region of HTLV-1 SU contains a novel site for direct binding of virus to the Nrp1 b1 domain. Our biophysical characterization of the SU peptides may help in developing inhibitors of HTLV-1 entry. PMID- 29458187 TI - MRI techniques to measure arterial and venous cerebral blood volume. AB - The measurement of cerebral blood volume (CBV) has been the topic of numerous neuroimaging studies. To date, however, most in vivo imaging approaches can only measure CBV summed over all types of blood vessels, including arterial, capillary and venous vessels in the microvasculature (i.e. total CBV or CBVtot). As different types of blood vessels have intrinsically different anatomy, function and physiology, the ability to quantify CBV in different segments of the microvascular tree may furnish information that is not obtainable from CBVtot, and may provide a more sensitive and specific measure for the underlying physiology. This review attempts to summarize major efforts in the development of MRI techniques to measure arterial (CBVa) and venous CBV (CBVv) separately. Advantages and disadvantages of each type of method are discussed. Applications of some of the methods in the investigation of flow-volume coupling in healthy brains, and in the detection of pathophysiological abnormalities in brain diseases such as arterial steno-occlusive disease, brain tumors, schizophrenia, Huntington's disease, Alzheimer's disease, and hypertension are demonstrated. We believe that the continual development of MRI approaches for the measurement of compartment-specific CBV will likely provide essential imaging tools for the advancement and refinement of our knowledge on the exquisite details of the microvasculature in healthy and diseased brains. PMID- 29458192 TI - Magnetic resonance imaging safety in nonconditional pacemaker and defibrillator recipients: A meta-analysis and systematic review. AB - BACKGROUND: Recommendations regarding performance of magnetic resonance imaging (MRI) in non-MRI conditional pacemaker and defibrillator recipients are evolving. Previous studies have suggested low adverse event rates with MRI in nonconditional cardiac implantable electronic device (CIED) recipients, but low power limits optimal characterization of risk. OBJECTIVE: The purpose of this study was to perform a systematic review and meta-analysis to characterize the clinical risk associated with MRI in CIED recipients in order to improve power. METHODS: PubMed and CINAHL indexed articles from 1990 to 2017 were queried. A random effects model was used for meta-analysis of continuous variables. Safety outcomes were evaluated with descriptive statistics. RESULTS: Seventy studies of non-MRI conditional devices undergoing MRI were identified, allowing for analysis of 5099 patients who underwent a total of 5908 MRI studies. Heterogeneity in lead parameter changes was observed within studies, although smaller variances were noted between studies. All lead characteristics and battery voltages showed very small, clinically insignificant changes when assessed as a pooled cohort, although cases of clinically relevant outcomes were also noted (lead failure 3, implantable cardioverter-defibrillator shock 1, electrical reset 94). Electrical resets were found only in older devices. Defibrillator function was unchanged, and inappropriate shocks were avoided with pre-MRI programming changes. CONCLUSION: This review demonstrated low lead failure and clinical event rates in non-MRI conditional pacemaker and defibrillator recipients undergoing MRI. Observed changes were small and interstudy variance was low, suggesting that the composite event rates offer a reasonable estimate of true effect. The observed adverse events reinforce the need for ongoing vigilance and caution, particularly with older devices. PMID- 29458193 TI - Attenuation of neuro-inflammation improves survival and neurodegeneration in a mouse model of severe neonatal hyperbilirubinemia. AB - All pre-term newborns and a high proportion of term newborns develop neonatal jaundice. Neonatal jaundice is usually a benign condition and self-resolves within few days after birth. However, a combination of unfavorable complications may lead to acute hyperbilirubinemia. Excessive hyperbilirubinemia may be toxic for the developing nervous system leading to severe neurological damage and death by kernicterus. Survivors show irreversible neurological deficits such as motor, sensitive and cognitive abnormalities. Current therapies rely on the use of phototherapy and, in unresponsive cases, exchange transfusion, which is performed only in specialized centers. During bilirubin-induced neurotoxicity different molecular pathways are activated, ranging from oxidative stress to endoplasmic reticulum (ER) stress response and inflammation, but the contribution of each pathway in the development of the disease still requires further investigation. Thus, to increase our understanding of the pathophysiology of bilirubin neurotoxicity, encephalopathy and kernicterus, we pharmacologically modulated neurodegeneration and neuroinflammation in a lethal mouse model of neonatal hyperbilirubinemia. Treatment of mutant mice with minocycline, a second generation tetracycline with anti-inflammatory and neuroprotective properties, resulted in a dose-dependent rescue of lethality, due to reduction of neurodegeneration and neuroinflammation, without affecting plasma bilirubin levels. In particular, rescued mice showed normal motor-coordination capabilities and behavior, as determined by the accelerating rotarod and open field tests, respectively. From the molecular point of view, rescued mice showed a dose dependent reduction in apoptosis of cerebellar neurons and improvement of dendritic arborization of Purkinje cells. Moreover, we observed a decrease of bilirubin-induced M1 microglia activation at the sites of damage with a reduction in oxidative and ER stress markers in these cells. Collectively, these data indicate that neurodegeneration and neuro-inflammation are key factors of bilirubin-induced neonatal lethality and neuro-behavioral abnormalities. We propose that the application of pharmacological treatments having anti inflammatory and neuroprotective effects, to be used in combination with the current treatments, may significantly improve the management of acute neonatal hyperbilirubinemia, protecting from bilirubin-induced neurological damage and death. PMID- 29458195 TI - Human dorsal root ganglion pulsed radiofrequency treatment modulates cerebrospinal fluid lymphocytes and neuroinflammatory markers in chronic radicular pain. AB - Radicular pain is a common cause of disability. Traditionally treatment has been either epidural steroid injection providing short-term relief or surgery with associated complications. Pulsed radiofrequency (PRF) applied to the dorsal root ganglion (DRG) is a minimally invasive day-care treatment, which is gaining significant clinical acceptance in a selective group of patients with pure radicular pain. Greater insights into the immunomodulatory effects of this procedure may help to further optimise its application and find alternative treatment options. We have examined it's effect on lymphocyte frequencies and secreted inflammatory markers in the cerebrospinal fluid (CSF) and correlated this with clinical outcome to identify clinical markers of chronic radicular pain. Ten patients were recruited for the study. CSF lymphocyte frequencies and levels of cytokines, chemokines and growth factors were quantified using flow cytometry and enzyme-linked immunosorbent assay (ELISA), respectively. Clinical assessment utilised Brief Pain Inventory scores. Nine out of ten patients (90%) demonstrated significant reduction in pain severity (p = 0.0007) and pain interference scores (p = 0.0015) three months post-treatment. Our data revealed significant reductions in CD56+, CD3-, NK cell frequencies (p = 0.03) and IFN gamma levels (p = 0.03) in treatment responders, while CD8+ T cell frequencies (p = 0.02) and IL-6 levels were increased (p = 0.05). IL-17 inversely correlated with post-treatment pain severity score (p = 0.01) and pre and post-treatment pain interference scores (p = 0.03, p = 0.01). These results support the concept that chronic radicular pain is a centrally mediated neuroimmune phenomenon and the mechanism of action of DRG PRF treatment is immunomodulatory. PMID- 29458194 TI - Differential effects of acute versus chronic stress on ethanol sensitivity: Evidence for interactions on both behavioral and neuroimmune outcomes. AB - Acute alcohol intoxication induces significant alterations in brain cytokines. Since stress challenges also profoundly impact central cytokine expression, these experiments examined the influence of acute and chronic stress on ethanol-induced brain cytokine responses. In Experiment 1, adult male rats were exposed to acute footshock. After a post-stress recovery interval of 0, 2, 4, or 24 h, rats were administered ethanol (4 g/kg; intragastric), with trunk blood and brains collected 3 h later. In non-stressed controls, acute ethanol increased expression of Il-6 and IkappaBalpha in the hippocampus. In contrast, rats exposed to footshock 24 h prior to ethanol demonstrated potentiation of hippocampal Il-6 and IkappaBalpha expression relative to ethanol-exposed non-stressed controls. Experiment 2 subsequently examined the effects of chronic stress on ethanol related cytokine expression. Following a novel chronic escalating stress procedure, rats were intubated with ethanol. As expected, acute ethanol increased Il-6 expression in all structures examined, yet the Il-6 response was attenuated exclusively in the hippocampus in chronically stressed rats. Later experiments determined that neither acute nor chronic stress affected ethanol pharmacokinetics. When ethanol hypnosis was examined, however, rats exposed to chronic stress awoke at significantly lower blood ethanol levels compared to acutely stressed rats, despite similar durations of ethanol-induced sedation. These data indicate that chronic stress may increase sensitivity to ethanol hypnosis. Together, these experiments demonstrate an intriguing interaction between recent stress history and ethanol-induced increases in hippocampal Il-6, and may provide insight into novel pharmacotherapeutic targets for prevention and treatment of alcohol-related health outcomes based on stress susceptibility. PMID- 29458196 TI - Within-subject associations between inflammation and features of depression: Using the flu vaccine as a mild inflammatory stimulus. AB - BACKGROUND: Inflammation plays a role in mood and behavior that may be relevant to identifying risk factors and treatment for depression and other stress-related illnesses. The purpose of this study was to examine whether fluctuations in inflammation following a mild immune stimulus were associated with changes in daily reported features of depression for up to a week in a healthy sample of young adults. METHODS: Forty-one undergraduate students completed daily diaries of mood, feelings of social disconnection, sleep, and physical symptoms for one week before and after receiving the seasonal influenza vaccine. Circulating plasma interleukin-6 (IL-6) was measured via blood samples taken immediately before and one day after vaccination. RESULTS: There was a significant increase in circulating IL-6 from pre- to post-intervention (p = .008), and there was significant variability in the magnitude of IL-6 change. Greater increases in IL 6 were associated with greater mood disturbance on post-vaccine days, specifically depressed mood and cognitive symptoms. CONCLUSIONS: Minor increases in inflammation were associated with corresponding increases in features of depression, and these associations occurred in the absence of any physical symptoms. The influenza vaccine could be used to probe causal relationships with a high degree of ecological validity, even in high-risk and vulnerable populations, to better understand the role of inflammation in the pathogenesis of depression. PMID- 29458198 TI - Adverse childhood experiences and adult inflammation: Findings from the 1958 British birth cohort. AB - BACKGROUND: The relationship between adverse childhood experiences (ACE) and poorer health across the life course is well established. Increased chronic inflammation might be one mechanism through which these associations operate. The aim of this study was to explore the relationship between ACE and adult inflammation using a prospective longitudinal study. We also investigated whether associations were explained by life course socioeconomic, psychological and health behavioural factors, and whether associations differed by gender. METHODS: Multiply imputed data on 7464 participants of the National Child Development Study (1958 British birth cohort) were used. Prospectively collected data on ACE included care placement, physical neglect, parental separation, family history of offences, mental illness, domestic conflict and alcohol misuse across childhood (0-16 years). Adult inflammation was indicated by C-reactive protein (CRP), fibrinogen and Von Willebrand factor (vWF) at age 44/45. Multivariable linear regression models were used to estimate associations between ACE and adult inflammation. RESULTS: Graded associations for ACE with CRP and fibrinogen were observed (e.g. CRP: 1 ACE: 4.61% higher, 95% CI: -3.13, 12.97; 2+ ACE: 16.35% higher, 95% CI: 6.87, 26.66). Socioeconomic and health behavioral factors were found to particularly explain these associations. After inclusion of all covariates associations between ACE and mid-life inflammation were no longer significant. Associations did not differ for men and women. CONCLUSIONS: ACE were associated in a graded manner with adult inflammation in a British birth cohort. The association was explained by life course socioeconomic and health behavioral factors, in particular. This study highlights the importance of protecting children from ACE and its negative health effects, and in supporting children through education and into skilled, secure work.

AB - Intracerebral hemorrhage (ICH) is a detrimental type of stroke. Mouse models of ICH, induced by collagenase or blood infusion, commonly target striatum, but not other brain sites such as ventricular system, cortex, and hippocampus. Few studies have systemically investigated brain damage and neurobehavioral deficits that develop in animal models of ICH in these areas of the right hemisphere. Therefore, we evaluated the brain damage and neurobehavioral dysfunction associated with right hemispheric ICH in ventricle, cortex, hippocampus, and striatum. The ICH model was induced by autologous whole blood or collagenase VII S (0.075 units in 0.5 ul saline) injection. At different time points after ICH induction, mice were assessed for brain tissue damage and neurobehavioral deficits. Sham control mice were used for comparison. We found that ICH location influenced features of brain damage, microglia/macrophage activation, and behavioral deficits. Furthermore, the 24-point neurologic deficit scoring system was most sensitive for evaluating locomotor abnormalities in all four models, especially on days 1, 3, and 7 post-ICH. The wire-hanging test was useful for evaluating locomotor abnormalities in models of striatal, intraventricular, and cortical ICH. The cylinder test identified locomotor abnormalities only in the striatal ICH model. The novel object recognition test was effective for evaluating recognition memory dysfunction in all models except for striatal ICH. The tail suspension test, forced swim test, and sucrose preference test were effective for evaluating emotional abnormality in all four models but did not correlate with severity of brain damage. These results will help to inform future preclinical studies of ICH outcomes. PMID- 29458199 TI - Alpha-synuclein oligomers impair memory through glial cell activation and via Toll-like receptor 2. AB - Alpha-synuclein oligomers (alpha-synOs) are emerging as crucial factors in the pathogenesis of synucleinopathies. Although the connection between neuroinflammation and alpha-syn still remains elusive, increasing evidence suggests that extracellular moieties activate glial cells leading to neuronal damage. Using an acute mouse model, we explored whether alpha-synOs induce memory impairment in association to neuroinflammation, addressing Toll-like receptors 2 and 4 (TLR2 and TLR4) involvement. We found that alpha-synOs abolished mouse memory establishment in association to hippocampal glial activation. On brain slices alpha-synOs inhibited long-term potentiation. Indomethacin and Ibuprofen prevented the alpha-synOs-mediated detrimental actions. Furthermore, while the TLR2 functional inhibitor antibody prevented the memory deficit, oligomers induced memory deficits in the TLR4 knockout mice. In conclusion, solely alpha synOs induce memory impairment likely inhibiting synaptic plasticity. alpha-synOs lead to hippocampal gliosis that is involved in memory impairment. Moreover, while the oligomer-mediated detrimental actions are TLR2 dependent, the involvement of TLR4 was ruled out. PMID- 29458200 TI - Influence of treatment modality on morbidity and mortality in periprosthetic femoral fracture. A comparative study of 71 fractures treated by internal fixation or femoral implant revision. AB - INTRODUCTION: The incidence of periprosthetic femoral fracture is constantly increasing, with high associated morbidity and mortality. Surgical treatment is guided by the Vancouver classification, but the influence of type of treatment on morbidity and mortality has been little analyzed. The theoretical advantage of implant revision over internal fixation is that it should allow earlier weight bearing, although the impact of this on morbidity and mortality and autonomy has not been demonstrated. We conducted a case-control study, to assess the influence of type of treatment (implant revision or internal fixation) (1) on mobility and autonomy and (2) on morbidity and mortality. HYPOTHESIS: The study hypothesis was that clinical results and morbidity and mortality do not differ between these two types of treatment. METHODS: A retrospective study included 70 patients with a total of 71 femoral periprosthetic fractures treated between 2007 and 2014. Two treatment groups, comparable for mean age, gender and ASA and Parker scores, were studied. Mean age was 78+/-13.5years (range, 23-95years). Thirty-six fractures (50.7%) were treated by implant revision via a posterolateral approach, using a revision stem with (n=11) or without cement (n=25) (REVISION group); immediate postoperative weight-bearing was authorized. Thirty-five fractures (49.3%) were treated by open reduction and internal fixation, using a locking plate (ORIF group); weight-bearing was authorized only in the third month. Mean follow-up was 43+/-27months (range, 0.75-107months). RESULTS: Autonomy on Parker score was reduced by 2 points at 1year's follow-up. Mean preoperative scores were 7.32+/ 1.79 (range, 3-9) and 7.43+/-1.79 (range, 4-9) in the REVISION and ORIF group, respectively, (p=0.8), falling to 5.06+/-2.6 (range, 0-9) and 4.5+/-2.01 (range, 0-9) respectively at follow-up (p=0.349). Sixteen patients in the REVISION group versus 13 in the ORIF group had made adaptations in their home or changed place of residence (p=0.2). At last follow-up, 18 patients (28.6%) had died: 12 (37.5%) in the ORIF and 6 (19.3%) in the REVISION group (p<0.05). Survival with death as endpoint at a mean 3.5years was 88+/-11% in the REVISION group versus 51+/-11% in the ORIF group (p=0.02). Three implant replacements were performed in each group (p=0.83). Twelve medical or surgical complications occurred in the ORIF group (37.5%) and 11 in the REVISION group (34%) (p=0.9). CONCLUSION: Implant revision for periprosthetic femoral fracture showed significantly lower overall mortality than internal fixation, without difference in terms of treatment failure or complications requiring revision surgery. LEVEL OF EVIDENCE: Level III, case control study. PMID- 29458201 TI - Computer-assisted surgery in acetabular fractures: Virtual reduction of acetabular fracture using the first patient-specific biomechanical model simulator. AB - : Preoperative planning for the management of acetabular fracture is founded on geometric models allowing virtual repositioning of the bone fragments, but not taking account of soft tissue and the realities of the surgical procedure. The present technical note reports results using the first simulator to be based on a patient-specific biomechanical model, simulating the action of forces on the fragments and also the interactions between soft issue and bone: muscles, capsules, ligaments, and bone contacts. In all 14 cases, biomechanical simulation faithfully reproduced the intraoperative behavior of the various bone fragments and reduction quality. On Matta's criteria, anatomic reduction was achieved in 12 of the 14 patients (86%; 0.25mm+/-0.45 [range: 0-1]) and in the 12 corresponding simulations (86%; 0.42mm+/-0.51 [range: 0-1]). Mean semi-automatic segmentation time was 156min+/-37.9 [range: 120-180]. Mean simulation time was 23min+/-9 [range: 16-38]. The model needs larger-scale prospective validation, but offers a new tool suitable for teaching purposes and for assessment of surgical results in acetabular fracture. LEVEL OF EVIDENCE: IV: retrospective study. PMID- 29458202 TI - Validity of the intra-operative measurement of stem anteversion and factors for the erroneous estimation in cementless total hip arthroplasty using postero lateral approach. AB - BACKGROUND: Intra-operative estimation of stem anteversion in total hip arthroplasty (THA) using postero-lateral approach is made by the surgeon's visual assessment, using the tibia as a guide, with the assumption that tibial axis is vertical to the trans-epicondylar axis. However, the accuracy of the intra operative estimation has rarely been verified with postoperative CT-scans, with controversies regarding these measurements particularly in case of knee osteoarthritis. Therefore we performed a prospective study to: (1) determine the accuracy of the intra-operative measurement and (2) investigate factors affecting the discrepancy between the surgeon's estimation and the real stem anteversion. HYPOTHESIS: Intra-operative estimation of stem anteversion correlated with the real stem anteversion on CT-scan. PATIENTS AND METHODS: Sixty-seven THAs using cementless straight stems (65 patients) without ipsilateral total knee arthroplasty were prospectively evaluated to compare the intra-operative measurement of stem anteversion with the real stem anteversion on computed tomography (CT) scans. There were 33 men and 34 women with a mean age of 59.7years (range, 27-84years) at the time of surgery. Age, tibia plateau angle, native femoral anteversion, femoro-tibial angle, body mass index, operative site, gender, coronal and sagittal tilt of the stem, stem type, ipsilateral knee osteoarthritis, and preoperative diagnosis were analyzed to evaluate the factors affecting the discrepancy between the intra-operative and CT measurements. RESULTS: The intra-operative estimation (mean, 21.5 degrees +/-8.5 degrees ; range, 5.0 degrees -39.0 degrees ) was greater than the CT measurement (mean, 19.5 degrees +/-8.7 degrees ; range, 4.5 degrees -38.5 degrees ) by 2.0 degrees . The mean absolute value of discrepancy was 4.5 degrees . The correlation coefficient between intra-operative and CT measurements was 0.837. The femoro tibial angle was associated with the discrepancy between the two measurements. In the presence of genu varum deformity, the intra-operative measurement underestimated the stem anteversion. DISCUSSION: Although intra-operative estimation of stem anteversion was slightly greater than the real stem anteversion, there was an excellent correlation between the two. The femoro tibial angle should be considered to optimize the stem anteversion during cementless THA using postero-lateral approach. LEVEL OF EVIDENCE: Level III, prospective case control study. PMID- 29458203 TI - Precision pharmacology for Alzheimer's disease. AB - The complex multifactorial nature of polygenic Alzheimer's disease (AD) presents significant challenges for drug development. AD pathophysiology is progressing in a non-linear dynamic fashion across multiple systems levels - from molecules to organ systems - and through adaptation, to compensation, and decompensation to systems failure. Adaptation and compensation maintain homeostasis: a dynamic equilibrium resulting from the dynamic non-linear interaction between genome, epigenome, and environment. An individual vulnerability to stressors exists on the basis of individual triggers, drivers, and thresholds accounting for the initiation and failure of adaptive and compensatory responses. Consequently, the distinct pattern of AD pathophysiology in space and time must be investigated on the basis of the individual biological makeup. This requires the implementation of systems biology and neurophysiology to facilitate Precision Medicine (PM) and Precision Pharmacology (PP). The regulation of several processes at multiple levels of complexity from gene expression to cellular cycle to tissue repair and system-wide network activation has different time delays (temporal scale) according to the affected systems (spatial scale). The initial failure might originate and occur at every level potentially affecting the whole dynamic interrelated systems within an organism. Unraveling the spatial and temporal dynamics of non-linear pathophysiological mechanisms across the continuum of hierarchical self-organized systems levels and from systems homeostasis to systems failure is key to understand AD. Measuring and, possibly, controlling space- and time-scaled adaptive and compensatory responses occurring during AD will represent a crucial step to achieve the capacity to substantially modify the disease course and progression at the best suitable timepoints, thus counteracting disrupting critical pathophysiological inputs. This approach will provide the conceptual basis for effective disease-modifying pathway-based targeted therapies. PP is based on an exploratory and integrative strategy to complex diseases such as brain proteinopathies including AD, aimed at identifying simultaneous aberrant molecular pathways and predicting their temporal impact on the systems levels. The depiction of pathway-based molecular signatures of complex diseases contributes to the accurate and mechanistic stratification of distinct subcohorts of individuals at the earliest compensatory stage when treatment intervention may reverse, stop, or delay the disease. In addition, individualized drug selection may optimize treatment safety by decreasing risk and amplitude of side effects and adverse reactions. From a methodological point of view, comprehensive "omics"-based biomarkers will guide the exploration of spatio-temporal systems-wide morpho-functional shifts along the continuum of AD pathophysiology, from adaptation to irreversible failure. The Alzheimer Precision Medicine Initiative (APMI) and the APMI cohort program (APMI-CP) have commenced to facilitate a paradigm shift towards effective drug discovery and development in AD. PMID- 29458204 TI - A review of implantable biosensors for closed-loop glucose control and other drug delivery applications. AB - Closed-loop drug delivery promises autonomous control of pharmacotherapy through the continuous monitoring of biomarker levels. For decades, researchers have strived for portable closed-loop systems capable of treating ambulatory patients with chronic conditions such as diabetes mellitus. After years of development, the first of these systems have left the laboratory and entered commercial use. This long-awaited advance reflects recent development of chronically stable implantable biosensors able to accurately measure biomarker levels in vivo. This review discusses the role of implantable biosensors in closed-loop drug delivery applications, with the intent to provide a resource for engineers and researchers studying such systems. We provide an overview of common biosensor designs and review the principle challenges in implementing long indwelling sensors: namely device sensitivity, selectivity, and lifetime. This review examines novel advances in transducer design, biological interface, and material biocompatibility, with a focus on recent academic and commercial work which provide successful strategies to overcome perennial challenges. This review focuses primarily on the topics of closed-loop glucose control and continuous glucose monitoring biosensors, which make up the overwhelming majority of published research in this area. We conclude with an overview of recent advances in closed-loop systems targeting applications outside blood glucose management. PMID- 29458205 TI - Developing a stable aqueous enteric coating formulation with hydroxypropyl methylcellulose acetate succinate (HPMCAS-MF) and colloidal silicon dioxide as anti-tacking agent. AB - The purpose of this study was to use statistical design of experiments to develop a stable aqueous enteric coating formulation containing stabilizing excipients, such as polyethylene glycol that can minimize hydroxypropyl methylcellulose acetate succinate aggregation and minimize spray-nozzle clogging at elevated processing temperatures. The mechanisms of stabilization (i.e. charge stabilization and molecular interactions) were studied by performing zeta potential and FTIR studies. Electrostatic stabilization by sodium lauryl sulfate and hydrogen bonding by polyethylene glycol provided dispersion stability and yielded a stable aqueous coating formulation that prevented spray-nozzle clogging. An enteric coated tablet with better gastric resistance was obtained by incorporating fumed silica (Aerosil(r) R972) as the anti-tacking agent instead of talc. Dissolution testing on the riboflavin enteric coated tablets showed a good enteric release profile without releasing riboflavin in 0.1 N HCl, and completely disintegrating within 10 min in phosphate buffer (pH 6.8). PMID- 29458206 TI - Mucoadhesive self-emulsifying delivery systems for ocular administration of econazole. AB - AIM: Development of mucoadhesive self-emulsifying drug delivery systems (SEDDS) providing a prolonged ocular residence time for poorly soluble active pharmaceutical ingredient. METHODS: l-Cysteine was covalently linked to 6 mercaptonicotinamide. The obtained ligand, Cysteine-6-mercaptonicotinamide (Cys-6 MNA) was attached to Eudragit(r) L100-55 via a carbodiimide mediated amide bond formation. The resulting entirely S-protected thiolated Eudragit(r) L100-55 was characterized regarding the degree of modification as well as stability toward oxidation in the presence of strong oxidizing agent (H2O2). The S-protected thiolated Eudragit(r) L100-55 was incorporated into SEDDS via hydrophobic ion pairing with benzalkonium chloride (BAK) in a concentration of 2% (m/m). S protected thiolated Eudragit(r) L100-55-BAK ion pair SEDDS (S-protected thiolated EU-BAK SEDDS) were characterized regarding their physicochemical and mucoadhesive properties. Econazole nitrate (EN) was incorporated into SEDDS in concentration of 1% (m/m) and in vitro drug release was assessed. Furthermore, toxicity study was performed on procine corneas via resazurin assay. RESULTS: The entirely S protected thiolated Eudragit(r) L100-55 exhibited 282 +/- 78.25 umol of MNA per gram of polymer. Ellman's test confirmed no free thiol groups and stability study showed no significant increase in dynamic viscosity overtime. The droplet size of developed SEDDS in simulated lacrimal fluid was below 100 nm with polydispersity index below 0.3. S-protected thiolated EU-BAK SEDDS exhibited 2.5-fold higher mucoadhesive properties than blank SEDDS on ocular mucosa. S-protected thiolated EU-BAK SEDDS showed sustained EN release over period of 8 h and no pronounced corneal toxicity in 0.5% (m/v) concentration. CONCLUSION: Accordingly, these mucoadhesive SEDDS can be considered as promising ocular delivery system for EN. PMID- 29458207 TI - Co-spray drying of hygroscopic kanamycin with the hydrophobic drug rifampicin to improve the aerosolization of kanamycin powder for treating respiratory infections. AB - High dose delivery of drugs to the lung using a dry powder inhaler (DPI) is an emerging approach to combat drug-resistant local infections. To achieve this, highly aerosolizable powders are required. We hypothesized that co-spray-drying kanamycin, a hydrophilic hygroscopic antibiotic, with rifampicin, a hydrophobic antibiotic, would produce inhalable particles with surfaces enriched in rifampicin. Such particles would have higher aerosolization than kanamycin alone, and minimise the mass of powder for inhalation avoiding use of non-active excipients. Kanamycin was co-spray-dried with rifampicin using a Buchi Mini Spray dryer. All powders were inhalable in size (1.1-5.9 um) and noncrystalline. X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (ToF-SIMS) showed the surface of the combination powder was enriched with rifampicin. In vitro aerosolization (fine particle fraction) determined by next generation impactor (NGI), dramatically improved from 29.5 +/- 0.2% (kanamycin-only) to 78.2 +/- 1.3% (kanamycin-rifampicin combination). The combination powder was flake-shaped in morphology, stable at 15% and 53% RH and 25 +/- 2 degrees C during one-month storage in an open Petri dish, and non-toxic (up to 50 ug/mL) to human alveolar and bronchial cell-lines. Surface enrichment of kanamycin by hydrophobic rifampicin improves aerosolization, which may help to combat drug-resistant local infections by facilitating high dose delivery to deep lung. PMID- 29458208 TI - The use of fatty acids as absorption enhancer for pulmonary drug delivery. AB - A limitation in the systemic uptake of many inhalable drugs is the restricted permeation through the pulmonary epithelial layer barrier. One strategy to bypass the epithelial layer when delivering non-permeable drugs is to alter the paracellular transport, allowing the uptake of drugs into the systemic circulation. In this study, the potential of sodium decanoate (Na dec), docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) as absorption enhancers has been investigated to increase pulmonary paracellular permeability by modulating epithelial cells' tight junctions. By incorporating Na dec, DHA and EPA, separately, into a nebulising formulation, the aim was to enhance the absorption of a fluorescent marker (flu-Na, used as model drug) across pulmonary epithelial cells (Calu-3). Results indicate that the aerosol performance of all the nebulizing formulations containing absorption enhancers was significantly better than control. Furthermore, the in vitro cell assays demonstrated a significant increase in paracellular transport of the fluorescent marker with Na dec and DHA formulations. This finding supports the potential use ofDHA and Na dec to enhance epithelial transport of poorly permeable drugs delivered via inhalation. PMID- 29458209 TI - Dermal anti-oxidant, anti-inflammatory and anti-aging effects of Compritol ATO based Resveratrol colloidal carriers prepared using mixed surfactants. AB - In this study, Compritol ATO-based Resveratrol colloidal carriers (CCCs) were prepared and subjected to characterization and evaluation. In most formulae, the use of a binary-mixture of surfactants improved the physicochemical properties. CCC6 (containing P407/P188 as bi-surfactants) attained the highest drug loading, release efficiency during 24 h and occlusive effect for 48 h; in addition, it showed a uniform particle size distribution within the desired range. In-vivo studies were done based on the analysis of anti-oxidant markers [catalase (CAT), reduced glutathione (GSH) and superoxide dismutase (SOD)], anti-inflammatory markers [interleukin 6 (IL-6), interleukin 8 (IL-8) and rat Nuclear factor-kappa B (NF-kappaB)] and anti-wrinkling markers [matrix metalloproteinase (MMP-1) and Granulocyte-macrophage colony-stimulating factor (GM-CSF)], after UVB irradiation. Results were significantly different when comparing the positive control and the negative control groups (p < 0.05). Rats pre-treated with CCC6 showed a great amelioration, and the level of the biochemical markers was significantly different compared to those of the positive control group and those pre-treated with the drug suspension (p < 0.05). Also, the high skin protective effect of CCC6 was proved by visual and histopathological examination of the rats' skin. Therefore, the current study proves the beneficial effects of the designed dermal Resveratrol-loaded colloidal system. PMID- 29458210 TI - Preparation of a solid self-microemulsifying drug delivery system by hot-melt extrusion. AB - Hot-melt extrusion (HME) has gained increasing attention in the pharmaceutical industry; however, its potential in the preparation of solid self-emulsifying drug delivery systems (S-SMEDDS) is still unexplored. This study sought to prepare enteric S-SMEDDS by HME and evaluate the effects of the process and formulation variables on S-SMEDDS properties via Box-Behnken design. Liquid SMEDDS were developed, and carvedilol was used as a class II model drug. Mean size, polydispersity index (PdI) and zeta potential of the resulting microemulsions were determined. The extrudates were then obtained by blending the lipid mixture and HPMCAS using a twin-screw hot-melt extruder. SEM, optical microscopy and PXRD were used to characterize the extrudates. In vitro microemulsion reconstitution and drug release were also studied. L-SMEDDS gave rise to microemulsions with low mean size, PdI and zeta potential (140.04 +/- 7.22 nm, 0.219 +/- 0.011 and -9.77 +/- 0.86 mV). S-SMEDDS were successfully prepared by HME, and an HMPCAS matrix was able to avoid microemulsion reconstitution and retain drug release in pH 1.2 (12.97%-25.54%). Conversely, microemulsion reconstitution and drug release were gradual in pH 6.8 and complete for some formulations. Extrudates prepared at the lowest drug concentration and highest temperature and recirculation time promoted a complete and rapid drug release in pH 6.8 giving rise to small and uniform microemulsion droplets. PMID- 29458211 TI - Impact of formulation excipients on the thermal, mechanical, and electrokinetic properties of hydroxypropyl methylcellulose acetate succinate (HPMCAS). AB - Hydroxypropyl methylcellulose acetate succinate (HPMCAS) has been widely used in amorphous solid dispersions and as an enteric coating polymer. Under aqueous coating conditions and at elevated coating temperatures, HPMCAS particles tend to aggregate and clog the spray-nozzle, hence interrupting the coating process. This research focused on how plasticizers and surfactants, excipients used for aqueous coating, affect the properties and stability of HPMCAS. This information would be useful in identifying suitable excipients for developing a stable HPMCAS aqueous enteric coating formulation. Triethyl citrate was found to be the most compatible plasticizer with HPMCAS, and displayed suitable thermal and mechanical properties. PEG 4000, the co-plasticizer, provided dispersion stability by yielding a dispersible sediment without aggregation at the elevated processing temperatures. Zeta potential measurements indicated sodium lauryl sulfate (SLS) could be used as a potential stabilizing agent at concentrations above its critical micelle concentration (CMC). This study facilitated the understanding of the HPMCAS aggregation mechanism, in addition to identifying suitable stabilizing agents. These stabilizing excipients could potentially be used to develop a stable aqueous coating formulation that does not exhibit polymer aggregation and nozzle clogging during the coating process. PMID- 29458212 TI - Programmed drug delivery system based on optimized "size decrease and hydrophilicity/hydrophobicity transformation" for enhanced hepatocellular carcinoma therapy of doxorubicin. AB - Requirements on drug delivery systems to surmount a complex series of pathophysiological barriers bear "cascading contradictions", especially size and hydrophilicity/hydrophobicity contradiction. Herein, a programmed drug delivery system (GNPs-Dox-Lac) based on optimized "size decrease and hydrophilicity/hydrophobicity transformation" was developed by combination the gelatin nanoparticle (GNPs) and prodrug Doxorubicin-Lactose (Dox-Lac). The results showed that GNPs-Dox-Lac (133.3 nm) were kinetically stable in blood circulation and inclined to accumulate at the tumor site. Then the degradation of the GNPs triggered by tumor extracellular matrix metalloproteinase-2 (MMP2) led to the release of prodrug Dox-Lac (Mw 898 Da) to facilitate the tumor tissue penetration and cellular uptake. Last, pH-responsive disassociation of Dox-Lac in tumor cells resulted in the free Dox (Mw 543 Da) release to induce toxicity. As expected, GNPs-Dox-Lac achieved superior tumor inhibition rate of 90.8% with low toxicity in vivo, suggesting its potential for enhanced hepatocellular carcinoma (HCC) therapy of doxorubicin in future. PMID- 29458213 TI - Selective targeting and degradation of doxorubicin-loaded folate-functionalized DNA nanocages. AB - Selective targeting is a crucial property of nanocarriers used for drug delivery in cancer therapy. We generated biotinylated octahedral DNA nanocages functionalized with folic acid through bio-orthogonal conjugation chemistry. Molecular modelling indicated that a distance of about 2.5 nm between folic acid and DNA nanocage avoids steric hindrance with the folate receptor. HeLa cells, a folate receptor positive tumour cell line, internalize folate-DNA nanocages with efficiency greater than 40 times compared to cells not expressing the folate receptors. Functionalized DNA nanocages are highly stable, not cytotoxic and can be efficiently loaded with the chemotherapeutic agent doxorubicin. After entry into cells, doxorubicin-loaded nanoparticles are confined in vesicular structures, indicating that DNA nanocages traffic through the endocytic pathway. Doxorubicin release from loaded DNA cages, facilitated by low pH of endocytic vesicles, induces toxic pathways that, besides selectively killing folate receptor-positive cancer cells, leads to cage degradation avoiding nanoparticles accumulation inside cells. PMID- 29458214 TI - Effect of tetrahedral DNA nanostructures on proliferation and osteo/odontogenic differentiation of dental pulp stem cells via activation of the notch signaling pathway. AB - Dental pulp stem cells (DPSCs) derived from the human dental pulp tissue have multiple differentiation capabilities, such as osteo/odontogenic differentiation. Therefore, DPSCs are deemed as ideal stem cell sources for tissue regeneration. As new nanomaterials based on DNA, tetrahedral DNA nanostructures (TDNs) have tremendous potential for biomedical applications. Here, the authors aimed to explore the part played by TDNs in proliferation and osteo/odontogenic differentiation of DPSCs, and attempted to investigate if these cellular responses could be driven by activating the canonical Notch signaling pathway. Upon exposure to TDNs, proliferation and osteo/odontogenic differentiation of DPSCs were dramatically enhanced, accompanied by up regulation of Notch signaling. In general, our study suggested that TDNs can significantly promote proliferation and osteo/odontogenic differentiation of DPSCs, and this remarkable discovery can be applied in tissue engineering and regenerative medicine to develop a significant and novel method for bone and dental tissue regeneration. PMID- 29458215 TI - Factors Associated with Placental Vascularization Measured by 3D Power Doppler Ultrasonographic Sphere Biopsy between 11 and 14 Weeks of Gestation. AB - OBJECTIVE: Preeclampsia is associated with placental vascularization disorders. Ultrasonographic sphere biopsy (USSB) of the placenta can estimate the vascularization of the placenta and potentially the risk of preeclampsia. We aimed to explore the factors related to placental vascularization measured with USSB in the first trimester. STUDY DESIGN: A prospective cohort was conducted in women recruited at 11 to 14 weeks. Three-dimensional acquisition of the placenta with power Doppler was undertaken along with crown-rump length (CRL). Using USSB of the full placental thickness at its center, vascularization index, flow index, and vascular flow index were measured. Pearson's correlation coefficients and multivariate linear regression were used to correlate the vascularization indices with CRL and maternal characteristics. RESULTS: A total of 5,612 women were recruited at a mean gestational age of 12.8 +/- 0.6 weeks. We observed that vascularization indices increase with CRL. After adjustment, we observed that maternal age, ethnicity other than Caucasian, and body mass index were associated with lower vascularization indices, while diabetes, smoking, and assisted reproduction technology were not. We observed that parous women without history of preeclampsia had greater vascularization indices compared with nulliparous women. CONCLUSION: Placental vascularization indices assessed by USSB fluctuate with gestational age, ethnicity, maternal age, body mass index, and previous pregnancy history. PMID- 29458216 TI - Institution of a Comprehensive Postpartum Hemorrhage Bundle at a Large Academic Center does not Immediately Reduce Maternal Morbidity. AB - OBJECTIVE: Obstetric hemorrhage is a leading cause of morbidity and mortality. We sought to assess whether institution of a postpartum hemorrhage (PPH) bundle could improve maternal morbidity in our population. STUDY DESIGN: Preintervention data (PRE) was collected on all deliveries at Hospital of the University of Pennsylvania between October 15, 2013 and December 15, 2013. A two pronged, multidisciplinary educational and procedural intervention related to PPH was instituted from March 2015 to June 2015. Postintervention data (POST) was collected on all deliveries from October 20, 2015 to December 20, 2015. RESULTS: Note that 592 of 626 (95%) PRE and 583 of 613 (95%) POST deliveries were included. The rates of PPH by estimated blood loss (EBL) >= 1,000 mL and by 3 g hemoglobin drop were not significantly different from PRE to POST (9.0% versus 12.2%, p = 0.07 and 10.5% versus 13.5%, p = 0.10, respectively). There was no significant change in transfusion rate (3.4% versus 5.1%, p = 0.13). Use of uterotonics was reduced from 9.8 to 6.3% from PRE to POST (p = 0.03). CONCLUSION: While institution of a PPH bundle is designed to improve the morbidity of PPH, our data demonstrate that it cannot be expected to do so within 6 months of implementation. Further studies will need to assess the long-term effects of such a resource-intensive protocol, including perceptions of improved safety by all providers, nurses, and staff. PMID- 29458217 TI - A New Two-Dimensional Shear Wave Elastography for Noninvasive Assessment of Liver Fibrosis in Healthy Subjects and in Patients with Chronic Liver Disease. AB - PURPOSE: To assess the performance of two-dimensional shear wave elastography (2D-SWE) on the GE LOGIQ E9 ultrasound system in a cohort of healthy subjects and to investigate its accuracy in the staging of liver fibrosis in patients with chronic liver disease (CLD) using liver biopsy as a reference standard. MATERIALS AND METHODS: From October 2014 to June 2016, 54 healthy subjects and 174 patients with CLD were consecutively enrolled. Liver fibrosis stage was assessed by the METAVIR scoring system. 18 (10.3 %) and 17 (9.8 %) patients had advanced fibrosis and cirrhosis, respectively. The correlation of liver stiffness measurement (LSM) and continuous variable was assessed using the Spearman rank correlation. The accuracy of 2D-SWE was evaluated with areas under the receiver operating characteristics curves (AUROC). RESULTS: Reliable LSMs were obtained in all subjects. The interobserver agreement ICC was excellent: 0.847. In healthy subjects, gender, but not anthropometric and biochemical data, were correlated with LSM. In patients with CLD, LSM had a strong positive correlation with fibrosis stage (rho = 0.628; p > 0.001). The AUROC was 0.724 for mild fibrosis (F>= 1), 0.857 for moderate fibrosis (F>= 2), 0.946 for severe fibrosis (F>= 3), and 0.935 for cirrhosis (F4). Likewise, good accuracy was observed in the HCV subgroup. The optimal cut-off value in differentiating healthy subjects from CLD patients with any fibrosis was 5.47 kPa with an AUROC of 0.875. CONCLUSION: 2D SWE is a reliable and reproducible method to assess LSM with good diagnostic accuracy to assess liver fibrosis in patients with CLD. PMID- 29458218 TI - Effects of Curcuminoids Plus Piperine on Glycemic, Hepatic and Inflammatory Biomarkers in Patients with Type 2 Diabetes Mellitus: A Randomized Double-Blind Placebo-Controlled Trial. AB - INTRODUCTION: Curcuminoids have been shown to reduce glycemia and related complications in diabetes. In the present study, we evaluated the impact of curcuminoids plus piperine administration on glycemic, hepatic and inflammatory biomarkers in type 2 diabetes (T2D) patients. METHODS: T2D patients aged 18-65 years were enrolled in a randomized double-blind placebo-controlled trial and randomly allocated to standard-of-care treatment and dietary advises plus either curcuminoids (daily dose of 500 mg/day co-administered with piperine 5 mg/day) or placebo for a period of 3 months. Glycemic, hepatic and inflammatory parameters were measured at baseline and final conditions. RESULTS: A total of 100 subjects (50 in each group) completed the 3-month period of trial. A significant reduction was found in serum levels of glucose (-9+/-16 mg/dL vs. -3+/-11 mg/dL in curcuminoids and placebo groups, respectively; p=0.048), C-peptide (-0.6+/-0.8 ng/mL vs. 0.02+/-0.6 ng/mL; p<0.001) and HbA1c (-0.9+/-1.1% vs. -0.2+/-0.5%; p<0.001) after curcuminoids supplementation versus placebo group. Additionally, participants in the intervention group showed lower serum alanine aminotransferase (-2+/-6 vs. -1+/-5; p=0.032) and aspartate aminotransferase ( 3+/-5 vs. -0.3+/-4; p=0.002) levels compared with the placebo group. Finally, no significant differences in high-sensitivity C-reactive protein (hs-CRP) concentrations were observed between curcuminoids and placebo groups (p>0.05). CONCLUSION: The results of the present trial revealed a beneficial effect of curcuminoids plus piperine supplementation on glycemic and hepatic parameters but not on hs-CRP levels in T2D patients. PMID- 29458219 TI - Clinical, Endocrine and Imaging Characteristics of Patients with Primary Hypophysitis. AB - Primary hypophysitis (PH) is a rare disease with a poorly-defined natural history. Our aim was to characterise patients with PH at presentation and during prolonged follow-up. Observational retrospective study of 22 patients was conducted from 3 centres. In 14 patients, PH was confirmed histologically and in the remaining 8 clinically, after excluding secondary causes of hypophysitis. All patients had hormonal and imaging investigations before any treatment. Median follow up was 48 months (25-75%: 3-60). There was a female predominance with a female/male ratio: 3.4:1. Eight out of 22 patients had another autoimmune disease. Headaches and gonadal dysfunction were the most common symptoms. Five patients presented with panhypopituitarism; 17 patients had anterior pituitary deficiency, and 7 had diabetes insipidus. At presentation, 9 patients were treated surgically, 5 received replacement hormonal treatment, and 8 high-dose glucocorticoids from whom 5 in association with other immunosuppressive agents. Six patients showed complete recovery of pituitary hormonal deficiencies while 6 showed a partial recovery during a 5-year follow-up period. No difference was found between patients treated with surgery and those treated medically. The overall relapse rate was 18%. PH can be manifested with a broad spectrum of clinical and hormonal disturbances. Long-term follow-up is required to define the natural history of the disease and response to treatment, since pituitary hormonal recovery or relapse may appear many years after initial diagnosis. We suggest that surgery and immunosuppressive therapy be reserved for exceptional cases. PMID- 29458220 TI - Incidence of Autoimmune and Related Disorders After Resolution of Endogenous Cushing Syndrome in Children. AB - Glucocorticoids are widely used for immunosuppression in autoimmune diseases. After the resolution of hypercortisolemia, the immune system recovers allowing for autoimmune diseases to manifest. Here we investigated the presence of autoimmune and related diseases that developed after cure of endogenous Cushing syndrome (CS) in children. We identified 129 children who were diagnosed and successfully treated for endogenous CS at the National Institutes of Health from 1997 until 2017, and who were followed for at least 6 months after treatment. We performed a retrospective chart review analysis to identify the presence of autoimmune or related diseases after cure. Ten children were diagnosed with a new autoimmune or related disorder after resolution of hypercortisolemia. This results in a frequency of 7.8% of our pediatric CS population. The identified patients had a shorter duration of hypercortisolemia prior to diagnosis, but did not otherwise differ from the remaining patients. The various identified diseases were: celiac disease (n=1), psoriasis (n=1), Hashimoto thyroiditis (n=1), Graves disease (n=1), optic neuritis (n=2), skin hypopigmented lesions/vitiligo (n=2), allergic rhinitis/asthma (n=1), and neuropathy responding to glucocorticoid treatment (n=1). The reported time between the treatment of CS and diagnosis of autoimmune disorder ranged from 6 to 19 months. The presence of autoimmune or related diseases might be masked by the hypercortisolemic state in endogenous CS. After resolution of hypercortisolemia, the presentation of new autoimmune diseases or recurrence of previously known autoimmune conditions should be considered when concerning symptoms arise. PMID- 29458221 TI - Thyroid-Stimulating Hormone-Stimulated Human Adipocytes Express Thymic Stromal Lymphopoietin. AB - When recombinant human (rh) thyroid-stimulating hormone (TSH) is administered to thyroid cancer survivors, an acute extra-thyroidal effect raises pro-inflammatory cytokines and activates platelets. Thymic stromal lymphopoietin (TSLP) is a cytokine recently implicated in platelet activation. Our aim was to measure platelet microparticle levels after rhTSH stimulation in vivo, and to investigate TSLP expression in TSH-stimulated human adipocytes in culture. Blood samples for total and platelet microparticle analysis were obtained from thyroid cancer survivors before (day 1) and after rhTSH administration (day 5). Adipocytes, differentiated from stromal preadipocytes isolated from adipose tissue from surgical patients, were stimulated with TSH. TSLP mRNA expression, protein expression, and protein release into the adipocyte medium were measured. The level of platelet microparticles in thyroid cancer patients rose 5-fold after rhTSH stimulation. TSH upregulated TSLP mRNA expression in adipocytes in culture through a pathway that was inhibited by 66% by H89, a protein kinase A inhibitor. TSLP protein expression rose in response to TSH, and TSH-stimulated TSLP release into the medium was completely blocked by dexamethasone. In conclusion, TSLP is a novel TSH-responsive adipokine. Future studies will be needed to address the potential role of adipocyte-derived TSLP and whether it is linked to TSH dependent platelet activation. PMID- 29458222 TI - ? PMID- 29458223 TI - ? AB - INTRODUCTION: The evaluation of plasma levels of antidepressants may improve the treatment outcome. The aim was to verify adherence and adequacy of administered doses of antidepressants among patients hospitalized for inadequate outpatient therapeutic response. METHODS: Selective serotonin reuptake inhibitors or venlafaxine plasma levels were assessed on the first day of hospitalization and after 3 days of controlled administration. The patients were considered adherent if the plasma level on admission was within the interval of the minimum and maximum plasma level on the fourth day, expanded by 30%. The adequacy of antidepressant doses used during the outpatient treatment was assessed by comparing the plasma level on the fourth day with the therapeutic reference range. RESULTS: Out of 83 patients, 52 (62.7%) were adherent. The plasma levels of antidepressants on the fourth day were found to be within the therapeutic reference range in 35 (43.2%) patients. The same number manifested levels below the therapeutic reference range. In 11 (13.6%) patients, the levels were higher than recommended. No significant difference in rate of adherence was found among individual antidepressants. CONCLUSION: The results show that antidepressant nonresponders are frequently under-dosed or nonadherent. PMID- 29458224 TI - [Lubeck University Model for Physiotherapy]. AB - The aim of this paper is to describe the development of an innovative bachelor's degree program for physiotherapy directly affiliated with the medical department, which is a unique approach to making physiotherapy an academic course in Germany. The previous system for qualifying as a physiotherapist was amended by the adaption of qualification objectives resulting in a model that links scientific and vocational knowledge from the beginning of the study. Several lectures support interprofessionality. The vocational training is fully integrated into the curriculum. The exemplary concept is monitored by an extensive quality management program. The approach meets general recommendations of experts and can serve as a model for other universities. PMID- 29458225 TI - [Indication Quality: Concepts and Ethical Implications]. AB - BACKGROUND: In recent times - also due to new laws - a good "indication quality" has been called for. The aim of this paper is to contribute to the debate about "indication quality" by looking into the meaning of the term "indication" as well as the meaning of an adequate understanding of quality. METHODS: Initially, a conceptual analysis is made of how indication is an integral part of the therapeutic decision-making process between physician and patient, in which, next to evidence-based elements, also normative elements are included (step 1). In the second part, 2 different types of quality are contrasted (step 2): an externally quantifiable, standardized quality (Q-quality) and a quality pertaining to the individual physician, based on professional ethical values and principles (T quality). RESULTS: For good "indication quality" it is suggested that both types of quality are included. As for Q-Quality, quantitative measures with selected quality indicators are proposed. Regarding T-Quality, qualitative, discursive procedures are more appropriate. CONCLUSIONS: It is suggested that the term "indication quality" be used for the quality of the whole therapeutic decision making process including the indication itself. The indication should be based on profession-specific values rather than on other contextual or "private" ethical foundations. The legal and societal preconditions should set positive impulses for both ways of understanding the term "quality". PMID- 29458226 TI - [Outbreaks of Scabies in Schools and Use of Ivermectin]. AB - BACKGROUND: At Pentecost 2017 outbreaks of scabies occurred in three schools in Ploen County. Several classes were supposed to go on an excursion or had returned from an excursion with symptomatic kids. METHODS: Rapid investigation, on site outbreak confirmation, home visits of the environment of the index cases, simultaneous mass treatment and post exposure prophylaxis (PEP) with Ivermectin according to the outbreak characteristics were applied. RESULTS: The index case of school A was ill since 5 months, but was misdiagnosed as eczema. Not all cases were linked to this index case. The entire school was treated in three steps within a 10-day period: step 1 began 48 h after notification. The attack rate was 6.4% (19 out of 298 pupils). A total of 93% of the kids and 100% of the teaching staff were treated. For school B with two sporadic and independent cases, an alert warning was issued. In school C, the two classes with cases were treated and according to the contact pattern two further classes were physically examined: 7 out of 39 (18%) of the kids were symptomatic, but none in the contact classes. CONCLUSIONS: The endemicity of scabies appears to be much higher than previously assumed. With the use of Ivermectin, the local public health department could act quickly and demonstrate that interventional public health is possible. However, several obstacles had to be overcome, but parents and teachers were cooperative and thankful.

PMID- 29458228 TI - Efficacy of Epidural Analgesia after Laparotomy in Children. AB - BACKGROUND: Epidural analgesia (EDA) is used as postoperative pain treatment in children, but little is known about its efficacy after laparotomy in children. This retrospective study investigated the efficacy of postoperative EDA after laparotomy in children and the frequencies of adverse effects and complications. MATERIALS AND METHODS: Data of all children aged 0 to 18 years undergoing laparotomy and treated with EDA in our hospital from January 2014 to December 2015 were collected. EDA was classified as successful either if the catheter was removed when there was no further need, and the patient was comfortable with oral/rectal analgesics or when EDA was continued after intervention. RESULTS: Ninety children with a median age of 3.7 years were included in the study. In 65% (59/90), EDA was classified as successful. In 34% (20/59) of all successful cases, an additional intervention was needed. In 35% (31/90), the catheter was removed earlier than planned, in half of these cases after an intervention. The primary reason for earlier removal was inadequate analgesia and technical failure. Adverse effects occurred in 18% and complications in 1% of cases. The successful group was significantly younger than the unsuccessful (p = 0.003). CONCLUSION: EDA after laparotomy positively contributed to postoperative pain treatment in two-thirds of children. Numbers of adverse effects and complications were low. It is important to optimize pain management after laparotomy in children; thus, further prospective studies should focus on optimizing EDA and comparing EDA with other techniques of analgesia. PMID- 29458229 TI - Primary Closure versus Bedside Silo and Delayed Closure for Gastroschisis: A Truncated Prospective Randomized Trial. AB - BACKGROUND: We report a prospective randomized trial comparing primary closure (PC) to bedside silo and delayed closure (DC) for babies with gastroschisis. METHODS: Patients were randomized to PC versus DC. We excluded those with atresia/necrosis, <34 weeks' gestation, or congenital anomalies. The primary outcome was length of stay (LOS). RESULTS: A total of 38 patients were included from August 2011 to August 2016; 18 patients underwent DC and 20 PC. There were no differences in gestational age or birth weight. Fifty percent of PC patients were successfully closed with the rest closed at a median of 4 days (interquartile range [IQR]: 2-4 days). DC patients were closed at a median of 4 days after silo placement (IQR: 2-5.8 days). None of the patients in this series developed abdominal compartment syndrome after closure. Median LOS, median time to enteral tolerance, and median time on ventilation were not statistically different. Two patients (one DC and one PC) had bowel ischemia and necrosis following silo placement requiring reoperation. Four patients (two DC and two PC) were noted to have small umbilical defects; none have yet required operative correction. CONCLUSION: There were no differences seen between PC and DC in LOS, time to enteral feeds, or ventilator times. PMID- 29458230 TI - Perioperative Complications of Congenital Diaphragmatic Hernia Repair. AB - Although improvements have been made, the management of congenital diaphragmatic hernia (CDH) remains a major challenge for perinatologists and neonatal surgeons. Many aspects of the disease remain unknown and, being a rare entity, evidence based data are hard to find. Surgical morbidity is considerable and affects long term quality of life. Perioperative complications have been reviewed focusing on thoracoscopic repair. Intraoperative acidosis was more severe during thoracoscopy when compared with open surgery (OS), though it is possible that later neurodevelopment was not affected. Even so, strategies have been outlined to reduce acidosis, such as decreasing carbon dioxide (CO2) insufflation after reduction of the herniated viscera into the abdomen is complete. The risk of pleural complications decreased after introduction of gentle ventilation techniques and minimally invasive surgery (MIS); thus, the use of a prophylactic intraoperative thoracic tube is not routinely required. Recurrence rate was higher in large CDH and following MIS repair. Technical demands play an important role, therefore, in avoiding complications; every step of the OS technique must be strictly accomplished. In large defects, the use of prosthetic patch might reduce recurrence rate, even by MIS repair, once again only if technical demands are overcome with meticulous rules of suturing. Thoracoscopy significantly reduced the incidence of bowel obstruction and recovery time and improved cosmesis. The best approach of CDH is yet to be found, and it goes far beyond the management of perioperative complications. Meanwhile randomized controlled studies, namely on the outcome of thoracoscopic repair, are required to inform further practice. PMID- 29458231 TI - Perioperative Complications of Transanal Pull-through Surgery for Hirschsprung's Disease. AB - Transanal pull-through is currently one of the most commonly used operation to treat Hirschsprung's disease (HD) worldwide. It has undergone some technical modifications during the last decades and still contains variable surgical practices. As high quality comparative studies between different surgical approaches are missing, debate over the optimal operation for HD still continues. Transanal pull-through is associated with multiple potential complications, which may result in permanently impaired functional outcome, life-long morbidity, and significant social restrictions. Although some of the surgical complications can be successfully managed by repeated surgery, the best changes for optimal bowel function and fecal continence are lost. Surgical complications are best treated by efficient prevention with careful adherence to established surgical techniques and principles during the primary operation. PMID- 29458232 TI - Fibrinogen and Neopterin Is Associated with Future Myocardial Infarction and Total Mortality in Patients with Stable Coronary Artery Disease. AB - Systemic fibrinogen and neopterin are related to inflammation. We investigated the prognostic utility and possible interactions of these biomarkers in stable coronary artery disease (SCAD) patients undergoing coronary angiography. We included 3,545 patients with suspected stable angina with a median follow-up of 7.3 and 10.2 years for incident acute myocardial infarction (AMI) and all-cause mortality, respectively. Prospective associations were explored by Cox regression. Potential effect modifications were investigated according to strata of fibrinogen, neopterin or high-sensitivity troponin T (hsTnT) below and above the median, as well as gender and smoking habits. During follow-up, 543 patients experienced an AMI and 769 patients died. In a multivariable model, the hazard ratios (HRs; 95% confidence interval [CI]) per 1 SD increase for fibrinogen in relation to these endpoints were 1.30 (1.20, 1.42; p < 0.001) and 1.22 (1.13, 1.31; p < 0.001), respectively. For neopterin, the HRs (95% CI) were 1.31 (1.23, 1.40; p < 0.001) and 1.24 (1.15, 1.34; p < 0.001), respectively. No significant interaction between fibrinogen and neopterin was observed. The prognostic utility of neopterin for incident AMI was improved in patients with an hsTnT above the median, for total mortality in non-smokers, and for both total mortality and AMI in females. In conclusion, both fibrinogen and neopterin were associated with future AMI and total mortality, but had low discriminatory impact. No interaction was observed between these two biomarkers. The prognostic utility of neopterin was improved in patients with hsTnT levels above the median, and in females and non-smokers. PMID- 29458233 TI - Pharmacokinetic Modelling to Predict FVIII:C Response to Desmopressin and Its Reproducibility in Nonsevere Haemophilia A Patients. AB - BACKGROUND: Nonsevere haemophilia A (HA) patients can be treated with desmopressin. Response of factor VIII activity (FVIII:C) differs between patients and is difficult to predict. OBJECTIVES: Our aims were to describe FVIII:C response after desmopressin and its reproducibility by population pharmacokinetic (PK) modelling. PATIENTS AND METHODS: Retrospective data of 128 nonsevere HA patients (age 7-75 years) receiving an intravenous or intranasal dose of desmopressin were used. PK modelling of FVIII:C was performed by nonlinear mixed effect modelling. Reproducibility of FVIII:C response was defined as less than 25% difference in peak FVIII:C between administrations. RESULTS: A total of 623 FVIII:C measurements from 142 desmopressin administrations were available; 14 patients had received two administrations at different occasions. The FVIII:C time profile was best described by a two-compartment model with first-order absorption and elimination. Interindividual variability of the estimated baseline FVIII:C, central volume of distribution and clearance were 37, 43 and 50%, respectively. The most recently measured FVIII:C (FVIII-recent) was significantly associated with FVIII:C response to desmopressin (p < 0.001). Desmopressin administration resulted in an absolute FVIII:C increase of 0.47 IU/mL (median, interquartile range: 0.32-0.65 IU/mL, n = 142). FVIII: C response was reproducible in 6 out of 14 patients receiving two desmopressin administrations. CONCLUSION: FVIII:C response to desmopressin in nonsevere HA patients was adequately described by a population PK model. Large variability in FVIII:C response was observed, which could only partially be explained by FVIII-recent. FVIII: C response was not reproducible in a small subset of patients. Therefore, monitoring FVIII:C around surgeries or bleeding might be considered. Research is needed to study this further. PMID- 29458234 TI - Ultrasonographic anatomy of reproductive female leopard geckos (Eublepharis macularius). AB - Captive leopard geckos (Eublepharis macularius) often present to the exotic clinic for gastrointestinal impactions, follicular stasis, or dystocia. To our knowledge, normal ultrasonographic anatomy of these lizards has not been described. The objectives of this prospective, anatomic, analytical study were to develop ultrasound techniques for this species and to describe the normal sonographic anatomy of the head, coelomic cavity, and tail. Eleven, healthy, female leopard geckos were included. A linear array 13-18 MHz transducer was used. Geckos were sedated and restrained in dorsal recumbency for coelomic structure examination and in ventral recumbency for head and tail examinations. Sagittal and transverse images were acquired and authors recorded qualitative and quantitative ultrasonographic characteristics of anatomic structures. The ventral surface of the lungs, liver, gallbladder, caudal vena cava, portal vein, ventral abdominal vein, aorta, ovarian follicles, fat bodies, tail, and brain were visualized in 10 of 11 individuals. In one individual, molt precluded ultrasonographic examination. The heart, kidneys, urinary bladder, spleen, and pancreas were not visualized. The digestive tract was observed in 10 individuals but was too small to be measured. Findings from the current study could be used as a reference for future studies of leopard geckos. PMID- 29458235 TI - Altered cortical development in fetuses with isolated nonsevere ventriculomegaly assessed by neurosonography. AB - OBJECTIVES: To perform a comprehensive assessment of cortical development in fetuses with isolated nonsevere ventriculomegaly (INSVM) by neurosonography. METHODS: We prospectively included 40 fetuses with INSVM and 40 controls. INSVM was defined as atrial width between 10.0 and 14.9 mm without associated malformation, infection, or chromosomal abnormality. Cortical development was assessed by neurosonography at 26 and 30 weeks of gestation measuring depth of selected sulci and applying a maturation scale from 0 (no appearance) to 5 (maximally developed) of main sulci and areas. RESULTS: INSVM showed underdeveloped calcarine and parieto-occipital sulci. In addition, significant delayed maturation pattern was also observed in regions distant to ventricular system including Insula depth (controls 30.8 mm [SD 1.7] vs INSVM 31.7 mm [1.8]; P = .04), Sylvian fissure grading (>2 at 26 weeks: controls 87.5% vs INSVM 50%, P = .01), mesial area grading (>2 at 30 weeks: controls 95% vs INSVM 62.5%; P = .03), and cingulate sulcus grading (>2 at 30 weeks: controls 100% vs INSVM 80.5%; P = .01). CONCLUSIONS: Fetuses with INSVM showed underdeveloped cortical maturation including also regions, where effect of ventricular dilatation is unlikely. These results suggest that in a proportion of fetuses with INSVM, ventricular dilation might be related with altered cortical architecture. PMID- 29458236 TI - Medical Travel among Non-Seoul Residents to Seek Prostate Cancer Treatment in Medical Facilities of Seoul. AB - Purpose: This study aims to investigate the trend in medical travel by non-Seoul residents to Seoul for treatment of prostate cancer and also to investigate the possible factors affecting the trend. Materials and Methods: This study represents a retrospective cohort study using data from the Korean National Health Insurance System (KNHI) from 2002 to 2015. Annual trends were produced for proportions of patients who traveled according to the age group, economic status and types of treatment. Multiple logistic analysis was used to determine factors affecting surgeries at medical facilities in Seoul among the non-Seoul residents. Results: A total of 68,543 patients were defined as newly diagnosed prostate cancer cohorts from 2005 to 2014. The proportion of patients who traveled to Seoul for treatment, estimated from cases with prostate cancer-related claims, decreased slightly over nine years (28.0 at 2005 and 27.0 at 2014, p=0.02). The average proportion of medical travelers seeking radical prostatectomy increased slightly but the increase was not statistically significant (43.1 at 2005 and 45.4 at 2014, p=0.26). Income level and performance of robot-assisted radical prostatectomy were significant positive factors for medical travel to medical facilities in Seoul. Combined comorbidity diseases and year undergoing surgery were significant negative factors for medical travel to medical facilities in Seoul. Conclusion: The general trend of patients travelling from outside Seoul for prostate cancer treatment decreased from 2005 to 2014. However, a large proportion remained irrespective of direct distance from Seoul. PMID- 29458237 TI - Randomized Open Label Phase III Trial of Irinotecan Plus Capecitabine versus Capecitabine Monotherapy in Patients with Metastatic Breast Cancer Previously Treated with Anthracycline and Taxane: PROCEED Trial (KCSG BR 11-01). AB - Purpose: We investigated whether irinotecan plus capecitabine improved progression-free survival (PFS) compared with capecitabine alone in patients with human epidermal growth factor 2 (HER2) negative and anthracycline and taxane pretreated metastatic breast cancer (MBC). Materials and Methods: A total of 221 patients were randomly assigned to irinotecan (80 mg/m2, days 1 and 8) and capecitabine (1,000 mg/m2 twice a day, days 1-14) or capecitabine alone (1,250 mg/m2 twice a day, days 1-14) every 3 weeks. The primary endpoint was PFS. Results: There was no significant difference in PFS between the combination and monotherapy arm (median, 6.4 months vs. 4.7 months; hazard ratio [HR], 0.84; 95% confidence interval [CI], 0.63 to 1.11; p=0.84). In patients with triple-negative breast cancer (TNBC, n=90), the combination significantly improved PFS (median, 4.7 months vs. 2.5 months; HR, 0.58; 95% CI, 0.37 to 0.91; p=0.02). Objective response rate was numerically higher in the combination arm, though it failed to reach statistical significance (44.4% vs. 33.3%, p=0.30). Overall survival did not differ between arms (median, 20.4 months vs. 24.0 months; p=0.63). While grade 3 or 4 neutropenia was more common in the combination arm (39.6% vs 9.0%), hand-foot syndrome was more often observed in capecitabine arm. Quality of life measurements in global health status was similar. However, patients in the combination arm showed significantly worse symptom scales especially in nausea/vomiting and diarrhea. Conclusion: Irinotecan plus capecitabine did not prove clinically superior to single-agent capecitabine in anthracycline- and taxane-pretreated HER2 negative MBC patients. Toxicity profiles of the two groups differed but were manageable. The role of added irinotecan in patients with TNBC remains to be elucidated. PMID- 29458239 TI - Transmission of Helicobacter pylori. AB - The exact modes and routes of transmission of Helicobacter pylori (H. pylori) infection remain unproven. Studies showed that H. pylori bacteria can spread directly from one person to the other, or indirectly from an infected person to the environment. Presently, interpersonal pathways are more probable than environmental exposure routes. Person to person transmission can be mainly fecal oral or oral-oral. In the last 30 years many authors have investigated the main potential sources of H. pylori infections, vectors and risk factors for both fecal-oral and oral-oral routes of transmission, eating of contaminated food, drinking of contaminated water, and exposure to animals. They have tried to isolate H. pylori from feces, saliva, dental plaque. These aspects are the basis for the effective prevention of both H. pylori acquisition and gastroduodenal pathology associated with it. These issues will be discussed in this narrative review. PMID- 29458238 TI - Active contour configuration model for estimating the posterior ablative margin in image fusion of real-time ultrasound and 3D ultrasound or magnetic resonance images for radiofrequency ablation: an experimental study. AB - PURPOSE: The purpose of this study was to evaluate the accuracy of an active contour model for estimating the posterior ablative margin in images obtained by the fusion of real-time ultrasonography (US) and 3-dimensional (3D) US or magnetic resonance (MR) images of an experimental tumor model for radiofrequency ablation. METHODS: Chickpeas (n=12) and bovine rump meat (n=12) were used as an experimental tumor model. Grayscale 3D US and T1-weighted MR images were pre acquired for use as reference datasets. US and MR/3D US fusion was performed for one group (n=4), and US and 3D US fusion only (n=8) was performed for the other group. Half of the models in each group were completely ablated, while the other half were incompletely ablated. Hyperechoic ablation areas were extracted using an active contour model from real-time US images, and the posterior margin of the ablation zone was estimated from the anterior margin. After the experiments, the ablated pieces of bovine rump meat were cut along the electrode path and the cut planes were photographed. The US images with the estimated posterior margin were compared with the photographs and post-ablation MR images. The extracted contours of the ablation zones from 12 US fusion videos and post-ablation MR images were also matched. RESULTS: In the four models fused under real-time US with MR/3D US, compression from the transducer and the insertion of an electrode resulted in misregistration between the real-time US and MR images, making the estimation of the ablation zones less accurate than was achieved through fusion between real time US and 3D US. Eight of the 12 post-ablation 3D US images were graded as good when compared with the sectioned specimens, and 10 of the 12 were graded as good in a comparison with nicotinamide adenine dinucleotide staining and histopathologic results. CONCLUSION: Estimating the posterior ablative margin using an active contour model is a feasible way of predicting the ablation area, and US/3D US fusion was more accurate than US/MR fusion. PMID- 29458240 TI - Benign and malignant gastroduodenal diseases associated with Helicobacter pylori: a narrative review and personal remarks in 2018. AB - The subject of Helicobacter pylori continues to elicit worldwide interest in many research fields. Epidemiological data suggest that the prevalence of the infection is decreasing in Western/developed countries and even in some developing regions, but this is masked by the high prevalence in the most populous regions. Chronic gastritis, caused invariably by the bacterium, was again classified in Kyoto and Helicobacter pylori-associated gastritis was included as a distinct entity. The prevalence of peptic ulcers is decreasing, but bleeding ulcers are a challenging problem, with stable mortality levels even in the endoscopic era. With the extended use of endoscopy, gastric polyps (GP) have become more prevalent: some are associated with the infection, some are not. Autoimmune and Helicobacter-induced gastritis can share common pathogenetic mechanisms. Gastric cancer (GC) is ranked highly on mortality lists worldwide. Its surgical treatment has registered some progress though. Little, if any improvement has been achieved in the medical treatment of advanced GC. With proper organization, GC seems a preventable disease. In spite of many guidelines, the Pan-European registry of Helicobacter pylori management shows that eradication rates obtained in many places are suboptimal. A new therapeutic regimen was compiled with promising pilot results. The results obtained with vonaprazan are limited to Asia. New avenues of both antibiotic and non-antibiotic treatments are expected to accelerate the eradication of this ulcerogenic and carcinogenic bacterium. PMID- 29458241 TI - Management of Helicobacter pylori in Piedmont, Italy. AB - Helicobacter pylori (H. pylori) is a Gram-negative bacterium, usually acquired during childhood, whose natural habitat is the gastric lumen. H. pylori is accepted as the most important cause of gastritis and peptic ulcer in humans. Nevertheless, its important role in the pathogenesis of gastric cancer as well as in several extra-gastroduodenal diseases has been confirmed. The aim of this work is to discuss, for the first time in a single article, all publications concerning H. pylori infection arising from Piedmont region, Italy, where in 1893 Giulio Bizzozero was the first who observed and described spiral organisms in the stomach of animal models. A systematic review of all publications on the management of H. pylori in adults in Piedmont, based on a PubMed and a Scopus research from 1965 to 2017 was performed. The discussed aspects are the epidemiology, the study on gastric and extragastric diseases related to H. pylori, the diagnostic methods, the treatment of H. pylori infection, and the possibility of reinfection. In conclusions, with almost 70 publications, Piedmont has proudly maintained the tradition of the father of the H. pylori.

PMID- 29458243 TI - Mild-to-moderate hemoptysis: a diagnostic and clinical challenge. AB - Mild-to-moderate hemoptysis is defined as the expectoration of blood or blood streaked sputum originating from the lower respiratory tract, in volumes that do not immediately threaten the patient's life. Nevertheless, it is a very common respiratory symptom and the list of underlying respiratory or non-respiratory diseases is vast, ranging from the most worrying to more easily manageable etiologies. In this narrative review, we have analyzed the most recent recommendations inferred from the literature, in terms of diagnostic as well as therapeutic approach. PMID- 29458244 TI - Clinical and molecular characteristics of pulmonary sarcomatoid carcinoma. AB - Background/Aims: Pulmonary sarcomatoid carcinoma (PSC) is a poorly differentiated non-small cell lung cancer (NSCLC) that contains components of spindle or giant cells. Owing to its low prevalence, there are insufficient data regarding its clinical features, therapeutic strategies and prognosis. METHODS: The medical records of 26 patients diagnosed with PSC from January 2009 to June 2015 were reviewed and analyzed for clinicopathological characteristics, treatment modality, and outcomes. RESULTS: The median age was 69.5 years. Twenty-three patients (88%) were male. Twenty-four patients (92%) were smokers. The median time from symptom onset to diagnosis was one month. Eighteen patients (69%) were diagnosed at an advanced stage. Pleomorphic carcinoma was the most common subtype, and epidermal growth factor receptor (EGFR) mutation was positive in two of 11 patients. Among 13 patients tested for programmed death ligand 1 (PD-L1) immunohistochemistry assay, eight showed high expression of PD-L1. The median overall survival (OS) of all patients was 9.5 months. In total, 12 patients were treated with chemotherapy: nine with platinum-based doublet therapy, two with tyrosine kinase inhibitor, and one with docetaxel. Seven patients showed partial response or stable disease. The median OS and progression-free survival of patients who received chemotherapy were 8.7 and 2.8 months, respectively. Conclusions: PSC was more common in males, smokers, and the elderly, with worse prognosis than ordinary NSCLC; chemotherapy response was favorable, and EGFR mutation status and PD-L1 expression may offer more therapeutic options. PMID- 29458245 TI - Impact of sleep quality on clinical features of primary Sjogren's syndrome. AB - Background/Aims: This study aimed to investigate the inf luence of poor sleep quality on clinical features of primary Sjogren's syndrome (pSS). Methods: Sleep quality was cross-sectionally assessed using the Pittsburgh Sleep Quality Index (PSQI), and demographic, clinical, and laboratory data were collected from 115 Korean patients with pSS. The patients completed questionnaires on the European League Against Rheumatism (EULAR) SS Patient Reported Index (ESSPRI), quality of life (EuroQOL five dimensions questionnaire [EQ-5D]), fatigue (fatigue severity score [FSS]), and depression (Beck Depression Inventory [BDI] II]). Symptoms and patient global assessment (PGA) were evaluated with a 100-mm visual analogue scale (VAS). The EULAR sicca score (ESS), ESSPRI, and EULAR SS Disease Activity Index (ESSDAI) were calculated at study enrollment. Results: Fifty-three patients (46.1%) had poor sleep quality and 32.4% of 71 patients without depression were poor sleepers. Poor sleepers had a significantly lower EQ-5D or ESSDAI and a significantly higher FSS, BDI-II, PGA, ESS, ESSPRI, or VAS scores for extra glandular symptoms than good sleepers. Neutrophil and lymphocyte counts were significantly higher and immunoglobulin G levels tended to decrease in poor sleepers. Additionally, PSQI was negatively correlated with EQ-5D and ESSDAI and positively with ESS, FSS, BDI-II, PGA, VAS scores for their symptoms, and ESSPRI. Multivariate analysis revealed that poor sleep quality remained the independent determinants of the unsatisfactory symptom state (ESSPRI >= 5). Conclusions: Our results showed that poor sleep quality could significantly affect the patient oriented outcomes and physician-reported activity index of pSS patients through the various effects of sleep quality on the psychological or somatic symptoms and the immune system.

AB - Reperfusion therapy for patients presenting with an acute ST-segment elevation myocardial infarction (STEMI) involves primary percutaneous coronary intervention (PPCI) and concomitant dual antiplatelet therapy (DAPT) with combination of a P2Y12 inhibitor and acetylsalicylic acid (ASA). Decision regarding DAPT can be challenging clinically in the modern era with the evolution of newer stents, more potent antiplatelet agents and novel anticoagulant drugs in addition to an older patient population with multiple comorbidities. This review outlines the currently available antiplatelet treatments, and their place within the therapeutic timeline of a patient presenting with STEMI. PMID- 29458247 TI - Magic Touch(r): preliminary clinical evidence with a novel sirolimus drug coated balloon. AB - Drug-coated balloons (DCB) have been developed in recent years to overcome some of the drug-eluting stents limitations. There is an established indication for the use of DCB in the treatment of in-stent restenosis and they are also variably used in various setting, in particular small coronary vessels and bifurcations. Until 2016, all DCBs available in Europe eluted paclitaxel, a highly lipophilic drug with narrow therapeutic window. In April 2016 a new sirolimus-coated balloon (Magic Touch(r), Envision Scientific PVT, Bhatpore, India) obtained the CE Mark. This device shares a new-generation delivery system and is able to release in a few seconds an effective dosage of sirolimus. PMID- 29458248 TI - Revascularization strategies in STEMI with multivessel disease: when and how. AB - Acute ST-segment elevation myocardial infarction (STEMI) typically arises from total occlusion of an epicardial coronary artery, most often due to atherosclerotic plaque rupture/erosion and subsequent thrombus formation. Granted this, important angiographic information for patients presenting with STEMI is not only about the status of infarct-related artery (IRA) but also about the atherosclerotic disease burden and disease severity of non-IRA vessels. Previous studies have reported that multivessel coronary artery disease is found in approximately 50% of patients with STEMI undergoing primary percutaneous coronary intervention (PCI). Primary PCI is now considered the gold standard in the treatment for patients with STEMI; however, the optimal reperfusion strategy in patients with STEMI and multivessel disease (MVD) remains uncertain. In this review, we summarize the available evidence on treatment options for patients with STEMI and MVD and highlight current guideline recommendations on this topic. PMID- 29458249 TI - Risk stratification in secondary cardiovascular prevention. AB - Although a substantial reduction in post-myocardial infaction mortality has been obtained in recent decades, one-year mortality rates are still high and 20% of patients who survive after the acute phase suffer a second cardiovascular event in the first year. In the setting of secondary cardiovascular prevention, the long-term cardiovascular risk stratification represents one of the most interesting and charming challenge for physician. Lifestyle changes and long-term control of traditional cardiovascular risk factors remain the cornerstone of secondary cardiovascular prevention and continue to offer the most powerful prognostic implications in the field of preventive cardiology with strong evidence of reduction in mortality and morbidity. In this regard, clinical, ECG, echocardiographic, cardiopulmonary exercise test data as well as biochemical markers of adverse prognosis are useful tool to identify patients at risk of developing future cardiovascular events. An integrated approach based on the analysis of all cardiovascular risk factors (traditional and emerging) along with instrumental and laboratory data represents the better way to predict prognosis in secondary cardiovascular prevention.

AB - The intermolecular [2+2] photocycloaddition of typical cyclic alpha,beta unsaturated enones, such as 2-cyclohexenone, with olefins was performed in moderate to good yields (42-82%) and with high enantioselectivity (82%-96% ee). An unusual substitution pattern at the chiral oxazaborolidine-AlBr3 Lewis acid complex that promotes the reaction was found to be crucial for the success of the reaction. The method was applied to the enantioselective synthesis of the monoterpene (-)-grandisol, which could be accomplished in six steps and with an overall yield of 13% starting from 3-methyl-2-cyclohexenone. PMID- 29458251 TI - Pushing Nonlinear Optical Oxides into the Mid-Infrared Spectral Region Beyond 10 MUm: Design, Synthesis, and Characterization of La3SnGa5O14. AB - Mid-infrared (mid-IR) coherent light is crucial for several applications in science as well as daily life, and its development especially in powerful augmentation is constrained by the availability of nonlinear optical (NLO) materials. The development of useful mid-IR NLO materials is limited by the requirements of a wide mid-IR transparent window, high laser damaged threshold (LDT), and strong NLO effect. It is common knowledge that oxides are not suitable mid-IR NLO materials, as their IR absorption cutoff wavelengths are usually <6 MUm; however, their LDTs and NLO effects can be large. Herein, we focused on langasite oxides and built structure-composition-property maps that describe the NLO properties in these materials by combining computational property prediction and experimental characterization. Accordingly, rational molecular design was performed, a new member of the langasite family, La3SnGa5O14 (LGSn), was synthesized, and single crystals were grown. The produced material exhibits the widest transparent region (0.27-11.0 MUm) among available oxides, the largest LDT (846 MW/cm2) among materials that are transparent to 10 MUm, and the strongest SHG effect among langasites. The discovery of LGSn facilitates the application of oxides as NLO crystals in the mid-IR spectral region beyond 10 MUm. More generally, the developed strategy could be used to guide and accelerate the systematic discovery of functional materials through understanding the key structure-composition-property relationships using the predictive power of computational tools. PMID- 29458252 TI - Selective Sensing and Imaging of Penicillium italicum Spores and Hyphae Using Carbohydrate-Lectin Interactions. AB - The blue-green mold Penicillium italicum is among the most problematic post harvest plant infections limiting the integrity of citrus and many other crops during storage and transportation, but there is no sensor for its on-site or field detection. We hereby, for the first time, report the development of novel biomolecular sensor for assessing the presence of P. italicum spores and hyphae using carbohydrate-lectin recognitions. Two approaches were developed: (i) lateral tests using standalone poly(amic) acid (PAA) membranes and glass surfaces and (ii) quantitative tests on 96-well polystyrene plates and paper electrodes. In both cases, the surfaces were functionalized with novel derivatized sugar based ligands while staining was performed with gold nanoparticles. Both approaches provided strong signals for 104 spores/mL of P. italicum isolated from experimentally infected lemons as the lowest-reliable concentration. The 96-well plate-based gave the most sensitive detection with a 4 * 102 spores/mL limit of detection, a linear dynamic range between 2.9 * 103 and 6.02 * 104 spores/mL ( R2 = 0.9939) and standard deviation of less than 5% for five replicate measurements. The selectivity of the ligands was tested against Trichaptum biforme, Glomerulla cingulata ( Colletotrichum gloeosporioides), and Aspergillus nidulans fungi species. The highest selectivity was obtained using the sugar-based gold nanoparticles toward both the spores and the hyphae of P. italicum. The advanced specificity was provided by the utilized sugar ligands employed in the synthesis of gold nanoparticles and was independent from size and shapes of the AuNPs. Accuracy of the sensor response showed dramatic dependence on the sample preparation. In the case of 5-10 min centrifugation at 600 rpm, the spores can be isolated free from hyphae and conidiophore, for which spiked recovery was up to 95% (std +/-4). In contrast, for gravity-based precipitation of hyphae, the spiked recovery was 88% (std 11).

AB - Some metal-organic frameworks (MOFs) incorporate nodes that are metal oxide clusters such as Zr6O8. Vacancies on the node surfaces, accidental or by design, act as catalytic sites. Here, we report elucidation of the chemistry of Zr6O8 nodes in the MOFs UiO-66 and UiO-67 having used infrared and nuclear magnetic resonance spectroscopies to determine the ligands on the node surfaces originating from the solvents and modifiers used in the syntheses and having elucidated the catalytic properties of the nodes for ethanol dehydration, which takes place selectively to make diethyl ether but not ethylene at 473-523 K. Density functional theory calculations show that the key to the selective catalysis is the breaking of node-linker bonds (or the accidental adjacency of open/defect sites) that allows catalytically fruitful bonding of the reactant ethanol to neighboring sites on the nodes, facilitating the bimolecular ether formation through an SN2 mechanism.

AB - INTRODUCTION: To report the results of a knowledge, attitude and practice (KAP) study related to diabetes mellitus (DM), hypertension and diabetic retinopathy (DR) of patient populations in India at different levels (Tertiary (T), Secondary (S) and Primary (P)) of a pyramidal model of eye health care. METHODS: In total, 202 participants, composed of equal numbers of diabetic and non-diabetic patients at a Tertiary urban facility (T), a Secondary rural facility (S) and a Primary (P) community-screening program, were surveyed on their knowledge, knowledge sources, attitudes, practices and factors that motivate use of eye health services. RESULTS: People with diabetes had a higher mean knowledge and attitude score about DM, hypertension and DR (67.3% T, 59.4% S, 47.0% P) than non diabetics (41.8% T, 29.0% S, 23.5% P; p<0.001). Awareness of DR was more 65.3% among diabetics compared with 22.0% among non-diabetics at all locations. Most participants in all locations were aware of hypertension (84.0% T, 65.3% S, 52.9% P), but few knew it could affect the eyes (30.0% T, 12.2% S, 13.7% P) or be associated with diabetic complications (30.0% T, 32.7% S, 21.8% P). Many participants had never previously had a dilated eye examination (2% T, 40% S, 50% P). Participants were motivated to visit an eye facility for a routine checkup (70.6%), poor vision (22.6%) or a glucose/blood pressure test (17.7%) at a Primary-level facility and for follow-up or poor vision at the other facilities (28% and 42% Tertiary, 50% and 30% Secondary). CONCLUSION: Practice-oriented education and advertising of facilities tailored for the relevant populations at each level of an eye health pyramid and continuation of fundus, glucose and blood pressure screening programs can help in creating awareness about diabetes, hypertension and diabetic retinopathy. PMID- 29458257 TI - Recruiting and Retaining Patient-Caregiver-Nurse Triads for Qualitative Hospice Cancer Pain Research. AB - BACKGROUND: Qualitative pain research for hospice patients with cancer and their caregivers involves recruiting and retaining participants with multiple vulnerabilities and ethical and logistical challenges. These have been reported for studies of individuals or dyads. However, there are no reports of the related challenges and outcomes where the sampled population was a hospice triad. OBJECTIVES: Qualitative research about pain management for home hospice patients with cancer contributes rich descriptive data and such studies are critical to improving cancer pain outcomes. We describe the ethical and pragmatic challenges we faced in a study of the hospice caring triad, operationalized as the patient, family caregiver, and nurse; how our study design anticipated them; and related outcomes. RESULTS: We found that having an established relationship with the hospice agency at which we recruited participants, clearly identifying potential participants at the onset of hospice care, practice using a recruitment script, patient recruitment of caregivers, establishing rapport, and participants determining when interviews should end helped us recruit and retain our sample. We were unable to accrue our anticipated triad sample, partially because of nurse gatekeeping and the condition at admission of patient participants who enrolled but had physical decline or died prior to written consent. CONCLUSIONS: Although researchers will always face challenges to enrolling individuals and groups in cancer pain studies, with careful study design, recruitment, and retention planning and research team-participant engagement, it is possible to gather a robust corpus of qualitative data. PMID- 29458258 TI - Broken bridges-new school transitions for students with autism spectrum disorder: A systematic review on difficulties and strategies for success. AB - Transitioning to a new school is often challenging for students with autism spectrum disorder. Few studies have examined the transition needs of students with autism spectrum disorder or the benefits of specific supports. This review synthesizes research findings on the difficulties that school transitions pose for students with autism spectrum disorder and their parents and teachers, and the strategies used to support students and parents during school transition. The review included 27 studies (10 examining the transition to primary school, 17 the transition to secondary school), with data from 443 students with autism spectrum disorder, 453 parents, and 546 teachers, across four continents (North America, Europe, Africa, and Australia). Studies reported that children with autism spectrum disorder struggled with anxiety and increased social pressure, their parents felt overwhelmed with complex placement decisions and worried about the well-being of their children, and teachers strove to provide appropriate supports to their students with autism spectrum disorder, often with inadequate resources. Findings indicated that the most useful strategies involved helping the student adjust to the new school setting, individualizing transition supports, clarifying the transition process for parents, and fostering communication both between the sending and receiving schools, and school and home.

PMID- 29458263 TI - Comparative study of nano and bulk Fe3O4 induced oxidative stress in Wistar rats. AB - CONTEXT: Magnetic nanomaterials (Fe3O4 NMs) have become novel tools with multiple biological and medical applications because of their biocompatibility. However, adverse health effects of these NMs are of great interest to learn. OBJECTIVE: This study was designed to assess the size and dose-dependent effects of Fe3O4 NMs and its bulk on oxidative stress biomarkers after post-subacute treatment in female Wistar rats. METHODS: Rats were daily administered with 30, 300 and 1000 mg/kg b.w. doses for 28 d of Fe3O4 NMs and its bulk for biodistribution and histopathological studies. RESULTS: Fe3O4 NMs treatment caused significant increase in lipid peroxidation levels of treated rats. It was also observed that the NM treatment elicited significant changes in enzyme activities of superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase and glutathione-S-transferase in treated rat organs with major reduction in glutathione content. Metal content analysis revealed that tissue deposition of NM in the organs was higher when compared to bulk and caused histological changes in liver. CONCLUSION: This study demonstrated that for same dose, NM showed higher bioaccumulation, oxidative stress and tissue damage than its bulk. The difference in toxic effect of Fe3O4 nano and bulk could be related to their altered physicochemical properties.

AB - Despite treatment advances that have improved the health and life expectancy of HIV-positive people and contribute to the prevention of HIV transmission, HIV stigma is still frequently experienced by HIV-infected individuals and those close to them. This study investigated the types of HIV-related stigma experienced by HIV-negative adults in serodiscordant heterosexual relationships when their partner's HIV-positive status was revealed to family and friends and their strategies to manage such stigma. In-depth interviews were conducted in New York City with 56 men and 44 women who were HIV negative and had been in a relationship for at least six months with an HIV-positive partner of the opposite sex. Those who had disclosed the HIV status of their partner to family or friends experienced four main types of stigmatizing behaviours: distancing (avoidance of the participant or his/her partner for fear of infection), depreciation of the partner (being told their partner is not worthy of them), violation of privacy (people spreading the information that the partner is HIV positive), or accusations (being told that it was wrong to be in a relationship with HIV positive people or to try to conceive with them). Participants described four main ways of managing actual or anticipated stigma: secrecy (not disclosing the HIV status of their partner to anyone), avoidance (breaking ties with people who held stigmatizing views), seeking support from their partner or the HIV-positive community (e.g., HIV-related organizations or their partner's family or friends), or education (informing family or friends about HIV treatment and prevention). Findings show that HIV-related "courtesy" stigma is frequently experienced by HIV negative people in serodiscordant relationships but often can be managed. Offering support to individuals in serodiscordant relationships can improve the quality of life of HIV-positive people and their HIV-negative partners and potentially reduce HIV stigma. PMID- 29458265 TI - Clean intermittent catheterization rates after initial and subsequent treatments with onabotulinumtoxinA for non-neurogenic overactive bladder in real-world clinical settings. AB - OBJECTIVE: Previous randomized controlled trials have reported a 6.1-6.9% incidence of clean intermittent catheterization (CIC) following treatment with onabotulinumtoxinA in non-neurogenic overactive bladder (OAB) patients who were inadequately managed by >=1 anticholinergic. A multi-center retrospective chart review assessed the real-world rate of voiding dysfunction requiring catheterization. METHODS: Patients received onabotulinumtoxinA 100 U (approved dose) administered by experienced injectors between January 2013 and June 2015. Patients using CIC or an indwelling catheter for >=24 hours for voiding dysfunction prior to onabotulinumtoxinA injections were excluded. The primary outcome was post-treatment CIC (lasting >24 hours; per individual physician's clinical judgment considering patient's voiding symptoms, post-void residual [PVR] urine volumes and patient bother). Potential baseline predictors of CIC (history of pelvic prolapse, cystocele, diabetes, PVR urine volume and age) were assessed using multivariable logistic regression. RESULTS: Overall, 299 patients received their first treatment with onabotulinumtoxinA 100 U. Mean age was 66.4 years; 98.3% were female. The incidence of CIC was 2.7% in the total study population after the first treatment with onabotulinumtoxinA. The de novo CIC rate in treatments 2 and 3 combined was similarly low (3.2%). None of the evaluated baseline characteristics were significant predictors of CIC initiation due to the low CIC incidence. CONCLUSIONS: This real-world study of non neurogenic OAB patients treated with onabotulinumtoxinA suggests that the CIC rate is lower than the rates reported in previous studies. There were no significant correlations between baseline predictors and CIC initiation, although statistical significance may not have been reached because of the low incidence of CIC. PMID- 29458266 TI - Acrylic acid grafted tamarind kernel polysaccharide-based hydrogel for bone tissue engineering in absence of any osteo-inducing factors. AB - PURPOSE: With increased life expectancy, disorders in lifestyle and other clinical conditions, and the changes in the connective tissues such as in bone, impose diverse biomedical problems. Cells belong to osteogenic lineages are extremely specific for their surface requirements. Therefore, suitable surfaces are the critical bottle neck for successful bone tissue engineering. This study involves assessment of polysaccharide-based hydrogel which effectively allows growth, differentiation and mineralisation of osteogenic cells even in the absence of osteogenic inducing factors. MATERIALS AND METHODS: Tamarind Kernel Polysaccharide was grafted with acrylic acid at different mole ratio. The critical parameter, surface morphology for bio application was assessed by SEM. MTT assay has been performed with hydrogels on Saos-2 cells. The biocompatibility and adhesion of different cell lines (F-11, Saos-2, Raw 264.7 and MSCs) on hydrogel surface was performed by Phalloidin and DAPI staining. Further the differentiation, mineralization and expression of different osteogenic markers, ALP assay, Alizarin Red staining and q-PCR was performed. RESULTS: The hydrogels show highly porous and interconnected pores. MTT assay demonstrates the hydrogel have no cytotoxicity towards Saos-2 cells and are suitable for proliferation of different lineage of cell lines. ALP, Alizarin red staining and q-PCR assay shows that the hydrogel surface enhances the differentiation, mineralization and expression of different osteogenic genes in Saos-2 cells in the absence of any osteogenic inducing factors. Conclusion Synthesized hydrogel surface triggers signalling events towards osteogenesis even in the absence of added growth factors. We proposed that this material can be used for effective bone tissue engineering in vitro at low cost. PMID- 29458267 TI - Can self-affirmation exacerbate adverse reactions to stress under certain conditions? AB - OBJECTIVE: Self-affirmation has repeatedly been shown to reduce adverse psychological and physiological responses to stress. However, it is plausible that self-affirmation could exacerbate negative reactions to stress under certain conditions. The current research explored whether self-affirmation would increase negative psychological responses to a stressor occurring in a central life domain characterised by low levels of control. DESIGN: Female participants (Study 1 N = 132; Study 2 N = 141) completed baseline measures of anxiety and mood. They were then randomly allocated to complete a self-affirmation or control task, before reading a narrative documenting a stressful birth and imagining themselves in the place of the woman giving birth. After completing this task, participants again reported their levels of anxiety and positive mood. MAIN OUTCOME MEASURES: Anxiety and positive mood assessed at follow-up. RESULTS: Study 1 demonstrated that self-affirmed women experienced increased anxiety and less positive mood at follow-up, compared both to baseline and to women in the control condition. Study 2 revealed that the effect of self-affirmation on outcomes was moderated by fear of childbirth. CONCLUSION: These results provide preliminary evidence that self affirmation may worsen negative responses to stressors under certain conditions and for certain individuals. PMID- 29458268 TI - PLHIV are more likely to have mental distress: evidence from a comparison of a cross-section of HIV and diabetes patients at Tertiary Hospitals in Nigeria. AB - : HIV is now regarded as a chronic disease because of the availability of treatment. However, it is not well known if there are differences (clinically and in magnitude) between the mental health status of PLHIV and people living with other chronic diseases. The aim of this study was to compare the mental health status of patients attending antiretroviral clinics to patients attending diabetes clinics at tertiary hospitals in Ogun State, Nigeria. A comparative hospital-based cross-sectional study of mental distress among 639 HIV-positive and 639 diabetic patients was carried out. Multivariate logistic regression analysis was used to control for confounders and to predict the probability of mental distress in PLHIV. The mean age of the participants was 44.87 (+/- 13.83) years and it had a range of 63 years (17 to 80). The prevalence of mental distress was higher among HIV-positive participants (46.79%) than diabetic participants (33.02%) (p < 0.0001). HIV-positive participants had greater odds of mental distress than diabetics (odds ratio = 1.78; 95% CI = 1.41-2.25). HIV positivity, female sex, lower levels of education, being unemployed, poorer housing conditions and separated, widowed or divorced were associated with higher odds of mental distress (p < 0.05). Mental distress was predicted by HIV positivity, occupation and current marital status. HIV infection and social inequalities are independent risk factors for mental distress. The odds of having mental distress is higher among PLHIV compared with diabetic patients. Addressing social inequalities might be the critical factor in the control of mental distress among PLHIV.

PMID- 29458269 TI - In vitro and in vivo evaluation of folate receptor-targeted a novel magnetic drug delivery system for ovarian cancer therapy. AB - Doxorubicin is widely used anticancer drug; however, use of doxorubicin is limited. Under externally applied magnetic field, magnetic agents can help to transport drug directly to tumor. Folate receptor is overexpressed in ovarian carcinomas. In this study, we aimed to develop magnetically responsive and folate receptor-targeted biomimetic drug delivery system for ovarian cancer therapy. Doxorubicin-loaded and glucose/gluconic acid-coated magnetic nanoparticles were synthesized and erythrocyte membrane vesicles were used for coating of nanoparticles. Folate ligand was anchored to surface so as to target receptor. Hydrodynamic size of nanocarrier was found as 91.2 +/- 20.8 nm. The results showed that delivery system has controlled drug release profile and biocompatible features. In folate-free medium, folate receptor-targeted nanocarrier showed 10.33-fold lower IC50 values for A2780 cells and 3.93-fold lower for OVCAR3 cells compared to non-targeted nanoparticles and demonstrated more cytotoxicity against ovarian cancer cells. Moreover, magnetically and folate receptor-targeted doxorubicin delivery system was significantly more effective for therapy of xenografted nude mice than free doxorubicin based on tumor shrinkages and biochemical parameters. In conclusion, it can be suggested that folate ligand attached and biomimetically designed magnetic drug delivery system have advantages and potential for targeted ovarian cancer therapy. PMID- 29458270 TI - The involvement of Nrf2 antioxidant signalling pathway in the protection of monocrotaline-induced hepatic sinusoidal obstruction syndrome in rats by (+) catechin hydrate. AB - Hepatic sinusoidal obstruction syndrome (HSOS) is a rare and life-threatening liver disease. (+)-Catechin is a natural dietary flavonol with high antioxidant capacity. This study aims to investigate the involvement of nuclear factor erythroid 2-related factor 2 (Nrf2) antioxidant signalling pathway in the protection of (+)-catechin hydrate (CAT) against monocrotaline (MCT)-induced HSOS. Results of serum alanine/aspartate aminotransferases (ALT/AST) activities, total bilirubin (TBil) and bile acids (TBA) amounts, liver histological observation, scanning electron microscope evaluation, and hepatic metalloproteinase-9 (MMP-9) expression all demonstrated the protection of CAT against MCT-induced HSOS in rats. CAT attenuated MCT-induced liver oxidative injury in rats and the formation of cellular reactive oxygen species (ROS) in human hepatic sinusoidal endothelial cells (HHSECs). CAT-enhanced Nrf2 nuclear translocation in livers from MCT-treated rats and in HHSECs treated with MCT, and further increased the expression of Nrf2-dependent genes including catalytic or modify subunit of glutamate-cysteine ligase (GCLC/GCLM), haem oxygenase-1 (HO-1) and NAD(P)H:quinone oxidoreductase 1 (NQO1). Moreover, GCL inhibitor L-buthionine (S, R)-sulfoximine (BSO), NQO1 inhibitor diminutol (Dim), and HO-1 inhibitor zinc protoporphyrin (ZnPP) all abrogated CAT-provided the protection against MCT induced cytotoxicity in HHSECs. The results of molecular docking analysis indicated the potential interaction of CAT with the Nrf2-binding site in kelch like ECH-associated protein-1 (Keap1) protein. In summary, this study demonstrated the critical involvement of Nrf2 antioxidant signalling pathway in CAT-provided the protection against MCT-induced HSOS. PMID- 29458271 TI - In vitro and in vivo evaluation of electrospun cellulose acetate/gelatin/hydroxyapatite nanocomposite mats for wound dressing applications. AB - The present study aimed to evaluate the efficacy of cellulose acetate/gelatin/nanohydroxyapatite (CA/Gel/nHA) nanocomposite mats as the wound dressing. The dressings were prepared with electrospinning of CA/Gel solutions containing 12.5, 25 and 50 mg nHA. The dressings were evaluated regarding their water uptake capacity, morphology, tensile strength, water vapour transmission rate, wettability and cellular response with L929 cell line. The results showed that the concentration of nHA had a direct correlation with porosity, water contact angle, water uptake, water vapor transmission rate and proliferation. In vivo studies showed that all dressings had higher wound closure percent than the sterile gauze, as the control. The highest wound closure value was achieved in the CA/Gel +25 mg nHA group, which showed 93.5 +/- 1.6%. The histological and the histomorphometric examinations of the wounds revealed that the CA/Gel +25 mg nHA dressing had the greatest collagen synthesis, re-epithelialization, neovascularization and also the best cosmetic appearance. Based on our finding, it could be concluded the applicability of electrospun nanofibrous CA/Gel/nHA dressings for successful wound treatment.

AB - INTRODUCTION: Colorectal cancer is one of the most common malignancies in the world, and it exhibits differences in incidence, pathogenesis, molecular pathways, and outcome depending on the location of the tumor. Differences in the microbiome, clinical characteristics, and chromosomal and molecular characteristics have been reported between the right and left side of the colon. Areas covered: This review focuses on the latest developments in epidemiological and chromosomal and molecular studies, which have enhanced our understanding on the underlying genetic and immunological differences between the right-sided colon and the left-sided colorectum in metastatic colorectal cancer. Expert commentary: The numerous findings regarding differences between right- and left sided colon cancers should have an impact on colorectal cancer screening and therapy. The location of the colorectal cancer should be considered before group stratification into genetic, clinical, and especially chemotherapy trials. A more tailored approach to colon cancer treatment would be highly desirable if future trials further support the hypothesis of two distinct tumor entities.

PMID- 29458274 TI - Nutrient composition, ruminal degradability and whole tract digestibility of whole crop maize silage from nine current varieties. AB - Since maize silage is an important forage in cattle nutrition, it is important to know its nutritive value. Much effort is put into breeding maize, and several new varieties are introduced on the market every year. This requires periodical analyses of the nutritive value of current maize varieties for the formulation of cattle rations. The aim of this study was to examine the nutritive value of whole crop maize silage (WCMS) from nine maize varieties in 3 consecutive years. For the analysis of nutrient composition and ruminal degradability of organic matter (OM), crude protein (CP), neutral detergent fibre (aNDFom) and non-fibre carbohydrates (NFC), varieties were harvested at three harvest dates (50%, 55% and 60% dry matter content in ear). Due to capacity limitations, the digestibility of WCMS was tested only for the middle harvest date. The CP and acid detergent fibre (ADFom) content was affected (p < 0.05) while aNDFom and NFC content was not influenced by variety. With advancing maturity, CP, aNDFom and ADFom content declined while NFC content increased. Variety influenced effective ruminal degradability (ED) of nutrients, except for CP. The ED of all examined nutrients decreased as maturity advanced from first to third harvest date. Digestibility of OM, ADFom and NFC was significantly and digestibility of aNDFom was tendentially (p = 0.064) influenced by variety. Additionally, an effect of year and a harvest date * year interaction was found for almost all examined parameters. In conclusion, variety, harvest date and year influence the nutritive value of WCMS. A comparison with earlier studies shows that current varieties have a higher fibre digestibility and a slower-ripening stover compared to older varieties. PMID- 29458275 TI - Structural damage and inflammation on radiographs or magnetic resonance imaging are associated with cortical interruptions on high-resolution peripheral quantitative computed tomography: a study in finger joints of patients with rheumatoid arthritis and healthy subjects. AB - OBJECTIVES: To study the relationship between structural damage and inflammatory features on magnetic resonance imaging (MRI) or radiography and other risk factors [anti-citrullinated protein antibody (ACPA) and/or rheumatoid factor (RF) seropositivity, hand dominance, disease duration] and the presence or number of cortical interruptions in finger joints on high-resolution peripheral quantitative computed tomography (HR-pQCT). METHOD: Finger joints of 38 healthy subjects and 39 patients with rheumatoid arthritis (RA) were examined through radiographs, MRI, and HR-pQCT. Radiographs were scored according to the Sharp/van der Heijde (SvH) method; MRI for the presence of cortical interruptions, bone marrow oedema (BMO), and synovitis; and HR-pQCT images for cortical interruptions. Descriptive statistics were calculated and associations examined using generalized estimating equations. RESULTS: Cortical interruptions were found in healthy subjects and patients with RA on HR-pQCT (mean +/- sd 0.33 +/- 0.63 vs 0.38 +/- 0.64 per joint quadrant, respectively, p < 0.01). Structural damage on MRI (cortical interruptions) or radiographs (SvH >= 1) was associated with the presence of cortical interruptions on HR-pQCT [odds ratio (OR) 12.4, 95% confidence interval (CI) 7.5-21.4, p < 0.01 and OR 4.8, 95% CI 1.9-11.7, respectively, p < 0.01]. The presence of BMO or synovitis was associated with more cortical interruptions on HR-pQCT (beta 0.47, 95% CI 0.4-0.6, p < 0.01 and beta 1.9, 95% CI 0.6-3.1, p < 0.01). In patients with RA, ACPA, and/or RF seropositivity, hand dominance and disease duration were not associated with more cortical interruptions on HR-pQCT. CONCLUSION: Structural damage and inflammatory features on MRI and radiographs are associated with cortical interruptions on HR pQCT. No association between other risk factors and cortical interruptions was demonstrated. PMID- 29458277 TI - Inductive Effect of a Ritonavir-Containing Hepatitis C Treatment Regimen on Warfarin in a Patient-A Case Report. AB - The warfarin management strategy for a mechanical mitral valve patient initiated on a ritonavir-based hepatitis C treatment regimen is described. A 62-year-old male with a past medical history of hepatitis C genotype 1a and stable warfarin dose history was initiated on a concomitant Viekira Pak(r) (VP) regimen containing ritonavir. Prior to initiation of the VP for hepatitis C treatment, the patient was stable on a warfarin dose of 40 mg/wk for 5 months. During treatment with VP, the patient experienced a markedly decreased international normalized ratio (INR) and warfarin requirements ultimately increased 125% from baseline (90 mg/wk). Effective anticoagulation management throughout and surrounding the treatment period for hepatitis C involved frequent warfarin dose adjustments, including preemptive changes, close monitoring, and repeated use of enoxaparin to ensure adequate thrombotic prophylaxis. This is believed to be the first reported case describing the management of warfarin in a patient with hepatitis C who received VP and required a drastically increased weekly warfarin dose. The possible mechanisms suggestive of this interaction and similar case reports in the literature are discussed. PMID- 29458276 TI - High doses of minocycline may induce delayed activation of microglia in aged rats and thus cannot prevent postoperative cognitive dysfunction. AB - Objective Postoperative cognitive dysfunction (POCD) is common after surgery in elderly patients and is associated with high morbidity. The molecular mechanisms responsible for POCD are unknown. Minocycline, an inhibitor of microglial activation, may be useful in treating and preventing POCD. We explored whether minocycline can inhibit microglial activation and prevent POCD in aged rats as a surgery model. Methods Rats aged 18 to 20 months were randomly allocated to the following groups: naive, abdominal surgery alone, or minocycline injection before abdominal surgery. Hippocampal cytokine mRNA levels were measured at 3 hours, 1 day, 3 days, and 7 days after surgery, and microglial activation was measured at 3 hours and 7 days after surgery. Memory was assessed using the Morris water maze test. Results Surgery resulted in severe cognitive impairment in aged rats and induced a significant neuroinflammatory response and microglial activation. The use of minocycline can prevent microglial activation after surgery, but delayed microglial activation may occur. The use of minocycline may further impair memory after surgery. Conclusion Minocycline can restrain microglial activation and restrict the inflammatory response in the hippocampus early after surgery, but it may induce delayed microglial activation and cannot prevent POCD in aged rats.

PMID- 29458278 TI - Secukinumab after anti-tumour necrosis factor-alpha therapy: a phase III study in active rheumatoid arthritis. AB - OBJECTIVE: To assess the efficacy and safety of secukinumab in patients with rheumatoid arthritis (RA) who failed to respond to tumour necrosis factor- alpha (TNF-alpha) inhibitors. METHOD: This phase III double-blind, double-dummy, placebo-controlled study (NCT01770379) randomized (1:1:1) patients to subcutaneous secukinumab 150 mg, secukinumab 75 mg, or placebo at baseline, weeks 1, 2, 3, and 4, and then every 4 weeks. American College of Rheumatology (ACR) 20 response at week 24 was the primary endpoint. Secondary outcomes included the 28 joint Disease Activity Score using C-reactive protein (DAS28-CRP), Health Assessment Questionnaire Disability Index (HAQ-DI), and ACR50 at week 24. Long term treatment was planned for 5 years. RESULTS: ACR20 response rates at week 24 for the secukinumab 150 mg and 75 mg groups were not statistically superior to placebo. None of the secondary endpoints was met for either secukinumab dose. Although not statistically significant, compared with placebo, numerically greater differences in least squares mean changes from baseline in HAQ-DI score and numerically higher ACR50 response rates were observed at week 24 in both secukinumab treatment groups. No new or unexpected adverse events were observed in this study compared with the large secukinumab safety database across psoriasis, psoriatic arthritis, ankylosing spondylitis, and other RA studies. CONCLUSIONS: Given that other second-line therapies have demonstrated efficacy in RA patients who failed to respond to TNF-alpha inhibitors, these findings may suggest that interleukin-17A inhibition with secukinumab does not provide additional benefit to these patients. This study further confirms the well characterized safety profile of secukinumab. PMID- 29458280 TI - Depressive Symptoms Are Associated With Color Vision but not Olfactory Function in Patients With Parkinson's Disease. AB - Depressive symptoms and sensory dysfunction, such as reduction in visual and olfactory function, are common in Parkinson's disease (PD). Previous studies have suggested that depressive symptoms are associated with visual impairments and potentially with hyposmia in several types of mood disorders. However, the relationship between depressive symptoms and sensory dysfunction remains unclear in PD. To examine the association of depressive symptoms with color vision and olfactory function in PD, the authors conducted a cross-sectional study in 159 patients with PD. Depressive symptoms were measured with the Beck Depression Inventory-II (BDI-II) and the 30-item Geriatric Depression Scale (GDS-30); color vision was tested with the Farnsworth-Munsell 100 Hue Test (FMT); and olfactory function was tested with the Sniffin' Sticks Screening 12 Test. Results showed that the total error score (TES) for the FMT was significantly and independently correlated with scores on both the BDI-II and GDS-30 in a positive manner, suggesting that more severe depressive symptoms are associated with poorer color vision in PD. In addition, both somatic and effective subscores for the BDI-II were correlated with the TES on the FMT, while no significant correlation was observed between total scores on the Sniffin' Sticks Screening 12 Test and BDI-II or GDS-30. The decrease in color vision but not olfactory function was found to be associated with the severity of depressive symptoms in PD patients, supporting the idea that the occurrence of depressive symptoms in PD is linked with disruption of the visual system. PMID- 29458281 TI - Construction of a Potential Telephone Assessment of Dementia Prevalence and Severity. AB - The "delta" (for "dementia") is a latent dementia phenotype that can be constructed by a unique confirmatory bifactor model in a structural equation model framework. Because it is derived from Spearman's general intelligence factor, "g," delta can be constructed from any cognitive battery. This may allow for accurate dementia case-finding by telephone and in the absence of expert clinical evaluation or review. The authors constructed a new delta homolog in a large ethnically diverse convenience sample: the Texas Alzheimer's Research and Care Consortium, comprising 2,016 participants (Alzheimer's disease [AD], N=920; mild cognitive impairment, N=277; normal controls, N=819). A delta composite ("dTEL") was extracted from informant-rated Instrumental Activities of Daily Living and a brief battery of verbal cognitive measures. The entire battery was engineered to be administered over the telephone. dTEL's model had excellent fit. dTEL correlated strongly with dementia severity, as measured by the Clinical Dementia Rating "sum of boxes" scale (r=0.78, p<0.001). The dTEL composite's area under the receiver operating characteristic curve for the discrimination between control subjects and AD patients was 0.97 (95% CI=0.964-0.975). This was superior to all dTEL indicators. Therefore, the authors have demonstrated that a delta homolog composite constructed entirely from verbal measures is strongly associated with dementia severity, can accurately diagnose dementia, and outperforms all observed measures from which it is constructed. Future studies are required to assess dTEL's performance relative to evaluation by expert clinicians when obtained by lay psychometricians over the telephone. PMID- 29458282 TI - Cost-effectiveness of hydrophilic-coated intermittent catheters compared with uncoated catheters in Canada: a public payer perspective. AB - STUDY DESIGN: A Markov model was used to analyze cost-effectiveness over a lifetime horizon. OBJECTIVE: To investigate the cost-effectiveness of hydrophilic coated intermittent catheters (HCICs) compared with uncoated catheters (UCs) among individuals with neurogenic bladder dysfunction (NB) due to spinal cord injury (SCI). SETTING: A Canadian public payer perspective based on data from Ontario; including a scenario analysis from the societal perspective. METHODS: A previously published Markov decision model was modified to compare the lifetime costs and quality-adjusted life years (QALYs) for the two interventions. Three renal function and three urinary tract infection (UTI) health states as well as other catheter-related events were included. Scenario analyses, including utility gain from compact catheter and phthalate free catheter use, were performed. Deterministic and probabilistic sensitivity analyses were conducted to evaluate the robustness of the model. RESULTS: The model predicted that a 50-year-old patient with SCI would gain an additional 0.72 QALYs if HCICs were used instead of UCs at an incremental cost of $48,016, leading to an incremental cost effectiveness ratio (ICER) of $66,634/QALY. Moreover, using HCICs could reduce the lifetime number of UTI events by 11%. From the societal perspective, HCICs cost less than UCs, while providing superior outcomes in terms of QALYs, life years gained (LYG), and UTIs. The cost per QALY further decreased when health related quality-of-life (HRQoL) gains associated with compact HCICs or catheters not containing phthalates were included. CONCLUSION: In general, ICERs in the range of CAD$50-100,000 could be considered cost-effective. The ICERs for the base case and sensitivity analyses suggest that HCICs could be cost-effective. From the societal perspective, HCICs were associated with potential cost savings in our model. The results suggest that reimbursement of HCICs should be considered in these settings. PMID- 29458283 TI - Falling caesarean section rate and improving intra-partum outcomes: a prospective cohort study. AB - OBJECTIVE: To evaluate caesarean section (CS) rates and moderate to severe hypoxaemic ischaemic encephalopathy (HIE) rates with other core intra-partum outcomes following reconfiguration of maternity services in Cardiff, South Wales, UK. DESIGN: Cohort study of births from 2006 to 2015. SETTINGS: A University tertiary referral centre for foetal and maternal medicine with 6000 births/year, University Hospital of Wales, United Kingdom. METHOD: Data relating to births from 1 January 2006 to 31 December 2015 were extracted from the computerized maternity database on a yearly basis. Case notes of all mothers and babies for the same duration were hand searched for documentation of HIE. HIE data was also collected prospectively by neonatologist (SC) and obstetrician (PA). MAIN OUTCOME MEASURES: Incidence of caesarean section births, babies with moderate to severe HIE, instrumental vaginal births, obstetric anal sphincter injuries (OASIS) associated with instrumental delivery, and major post-partum haemorrhage (MPPH) of 2500 mL or more. RESULTS: During this 10-year period, a downward trend in emergency CS rate was seen from 15.6% in 2006 to 10.5% in 2015, reducing total CS rate from 25.5% in 2006 to 21.2% in 2015. A downward trend in the incidence of moderate and severe HIE was seen over the same period. There was an increase in operative vaginal births (OVB) from 12.8% to 15%. The rate of spontaneous vaginal births (SVB) remained stable. The incidence of OASIS remained constant and MPPH rate has fallen. CONCLUSIONS: Following amalgamation of two medium sized obstetric units and the opening of a Midwifery Led Unit (MLU), core intrapartum outcomes have improved. Contributing factors are the introduction of regular multidisciplinary training with enhanced team working, compulsory education for obstetricians and midwives on cardiotocograph (CTG) interpretation, increased consultant presence on delivery suite, robust risk management systems and broad multidisciplinary agreement on clinical guidelines promoting vaginal birth. PMID- 29458284 TI - Technical analysis of US imaging for precise microwave ablation for benign breast tumours. AB - PURPOSE: To determine the characteristics of ultrasound (US) imaging of completely ablated cases and the effects of duration and clinical experience on accurate microwave ablation (MWA) for the treatment of benign breast tumours. METHODS: With written informed consent and approval of the institutional ethics committee, patients with symptomatic or palpable benign breast tumours (longest diameter, 7-32 mm), to whom MWA (2450 MHz) was performed, were enrolled in this prospective nonrandomised study. US and contrast-enhanced US (CEUS) images were applied for follow-up and analysed. RESULTS: Forty-seven consecutive patients with 52 completely ablated tumours were enrolled. Of these 52 tumour ablations in US, 16 ablations were defined as concentric type, and 36 were defined as nonconcentric type. Of these 52 ablations, 7 cases were defined as nonaccurate ablation with the largest margin >=10 mm in US. The nonaccurate ablation rate in the training group (the first consecutive 30 cases, 7/30) was significant higher than that (the last 22 cases, 0/22) in the practiced group (p = 0.016). Of 38 completely ablated cases (9 mm < the longest diameter <20 mm), the average largest margin in >70 s group was significant larger than that in <70 s group (p = 0.019). CONCLUSIONS: Experience was important for accurate MWA in the treatment of benign breast tumour, and at least 30 cases training was recommended. Nevertheless, clinical trials are still required to validate our findings in the future. PMID- 29458285 TI - Induction of autophagy by depolarization of mitochondria. AB - Mitochondrial dysfunction plays a crucial role in the macroautophagy/autophagy cascade. In a recently published study Sun et al. described the induction of autophagy by the membranophilic triphenylphosphonium (TPP)-based cation 10-(6' ubiquinonyl) decyltriphenylphosphonium (MitoQ) in HepG2 cells (Sun C, et al. "MitoQ regulates autophagy by inducing a pseudo-mitochondrial membrane potential [PMMP]", Autophagy 2017, 13:730-738.). Sun et al. suggested that MitoQ adsorbed to the inner mitochondrial membrane with its cationic moiety remaining in the intermembrane space, adding a large number of positive charges and establishing a "pseudo-mitochondrial membrane potential," which blocked the ATP synthase. Here we argue that the suggested mechanism for generation of the "pseudo-mitochondrial membrane potential" is physically implausible and contradicts earlier findings on the electrophoretic displacements of membranophilic cations within and through phospholipid membranes. We provide evidence that TPP-cations dissipated the mitochondrial membrane potential in HepG2 cells and that the induction of autophagy in carcinoma cells by TPP-cations correlated with the uncoupling of oxidative phosphorylation. The mild uncoupling of oxidative phosphorylation by various mitochondria-targeted penetrating cations may contribute to their reported therapeutic effects via inducing both autophagy and mitochondria selective mitophagy. PMID- 29458286 TI - Cost-effectiveness of ceritinib in previously untreated anaplastic lymphoma kinase-positive metastatic non-small cell lung cancer in the United States. AB - AIMS: To assess the cost-effectiveness of first-line ceritinib vs crizotinib and platinum doublet chemotherapy for anaplastic lymphoma kinase (ALK)-positive metastatic non-small cell lung cancer (NSCLC) from a US third-party payer's perspective. MATERIALS AND METHODS: A partitioned survival model with three health states (stable disease, progressive disease, death) was developed over a 20-year time horizon. Ceritinib's efficacy inputs (progression-free and overall survival) were estimated from ASCEND-4; parametric survival models extrapolated data beyond the trial period. The relative efficacy of ceritinib vs chemotherapy was obtained from ASCEND-4, the relative efficacy of ceritinib vs crizotinib was estimated using a matching-adjusted indirect comparison based on ASCEND-4 and PROFILE 1014. Drug acquisition, treatment administration, adverse event management, and medical costs were obtained from publicly available databases and the literature, and inflated to 2016 US dollars. Treatment-specific stable-state utilities were derived from trials and progressive-state utility from the literature. Incremental costs per quality-adjusted life year (QALY) were estimated for ceritinib vs each comparator. Cost-effectiveness was assessed based on US willingness-to-pay thresholds. Deterministic and probabilistic sensitivity analyses were performed to test model robustness. RESULTS: In the base case, first-line ceritinib was associated with total direct costs of $299,777 and 3.28 QALYs (from 4.61 life years gained [LYG]) over 20 years. First-line crizotinib and chemotherapy were associated with 2.73 and 2.41 QALYs, 3.92 and 3.53 LYG, and $263,172 and $228,184 total direct costs, respectively. The incremental cost per QALY gained was $66,064 for ceritinib vs crizotinib and $81,645 for ceritinib vs chemotherapy. In the first 2 years following treatment initiation, ceritinib dominated crizotinib by conferring greater health benefits at reduced total costs. Results were robust to deterministic and probabilistic sensitivity analyses. LIMITATIONS: In the absence of head-to-head trials, an indirect comparison method was used. CONCLUSIONS: Ceritinib is cost-effective compared to crizotinib and chemotherapy in the treatment of previously untreated ALK-positive metastatic NCSLC in the US. PMID- 29458287 TI - The economic impact of switching from Synthroid for the treatment of hypothyroidism. AB - AIMS: To compare hypothyroidism-related costs for patients who continuously used Synthroid and patients who switched from Synthroid to alternative therapies. MATERIALS AND METHODS: Truven's Health Analytics MarketScan Commercial Claims and Encounters database from January 1, 2007 to June 30, 2014 was queried for US adults diagnosed with hypothyroidism who initiated Synthroid and adhered to such therapy for at least 6 months. Propensity score matching matched continuous users of Synthroid to patients who switched from Synthroid to alternative levothyroxine agents. Kruskal-Wallis tests assessed differences between the matched cohorts in several categories of costs, including disease-related drug costs, non-drug medical costs, and total direct medical costs. RESULTS: There were 10,159 individuals included in the study, with 7,991 continuous users of Synthroid and 2,168 switchers. After matching (n = 2,052 for each cohort), continuous use of Synthroid was associated with significantly lower hypothyroidism-related non-drug medical costs ($595 vs $1,023; p = .003) and reduced hypothyroidism-related total medical costs ($757 vs $1,132; p = .010), despite being associated with significantly higher drug costs ($161 vs $109; p < .001). Hypothyroidism-related total medical costs rose as the number of switches of hypothyroidism treatment increased, with continuous users having significantly lower hypothyroidism related total medical costs ($757) compared with patients who switched twice ($1,179; p = .001) or three or more times ($1,268; p = .004). LIMITATIONS: The analyses focused on continuously insured patients who were adherent to Synthroid for at least 6 months and results may not be generalizable. The reliance on claims data does not allow for clinical examination of hypothyroidism or inclusion of some factors that may be associated with outcomes. The analyses assume that all prescriptions filled are taken as prescribed. CONCLUSIONS: Results indicate that there are significant direct economic healthcare costs associated with switching from Synthroid to alternative levothyroxine therapies, and that these costs increase as patients switch therapies more frequently. PMID- 29458289 TI - [Development of a program theory as a basis for the evaluation of a dementia special care unit]. AB - Background: An existing dementia special care unit should be evaluated. In order to build a sound foundation of the evaluation a deep theoretical understanding of the implemented intervention is needed, which has not been explicated yet. One possibility to achieve this is the development of a program theory. Aim: The aim is to present a method to develop a program theory for the existing living and care concept of the dementia special care unit, which is used in a larger project to evaluate the concept theory-drivenly. Method: The evaluation is embedded in the framework of van Belle et al. (2010) and an action model and a change model (Chen, 2015) is created. For the specification of the change model the contribution analysis (Mayne, 2011) is applied. Data were collected in workshops with the developers and the nurses of the dementia special care unit and a literature research concerning interventions and outcomes was carried out. The results were synthesized in a consens workshop. Results: The action model describes the interventions of the dementia special care unit, the implementers, the organization and the context. The change model compromises the mechanisms through which interventions achieve outcomes. Conclusions: The results of the program theory can be employed to choose data collection methods and instruments for the evaluation. On the basis of the results of the evaluation the program theory can be refined and adapted. PMID- 29458288 TI - Delipidation of mammalian Atg8-family proteins by each of the four ATG4 proteases. AB - During macroautophagy/autophagy, mammalian Atg8-family proteins undergo 2 proteolytic processing events. The first exposes a COOH-terminal glycine used in the conjugation of these proteins to lipids on the phagophore, the precursor to the autophagosome, whereas the second releases the lipid. The ATG4 family of proteases drives both cleavages, but how ATG4 proteins distinguish between soluble and lipid-anchored Atg8 proteins is not well understood. In a fully reconstituted delipidation assay, we establish that the physical anchoring of mammalian Atg8-family proteins in the membrane dramatically shifts the way ATG4 proteases recognize these substrates. Thus, while ATG4B is orders of magnitude faster at processing a soluble unprimed protein, all 4 ATG4 proteases can be activated to similar enzymatic activities on lipid-attached substrates. The recognition of lipidated but not soluble substrates is sensitive to a COOH terminal LIR motif both in vitro and in cells. We suggest a model whereby ATG4B drives very fast priming of mammalian Atg8 proteins, whereas delipidation is inherently slow and regulated by all ATG4 homologs. PMID- 29458290 TI - Neuregulin-1 accelerates corneal epithelial wound healing. AB - Corneal epithelial cells (CECs) play an important role in the function of the cornea, and are maintained by corneal epithelial stem cells (CESCs). Recent studies have shown that neuronal growth factors affect the proliferation and migration of CESCs. Neuregulin-1 (NR-1) is a neuronal growth factor that is expressed in the early stages of brain development. The aim of this study was to determine whether NR-1 activates corneal wound healing. We observed that NR-1 activated both proliferation and migration of CECs. In addition, the colony forming efficacy of CESCs was enhanced. In mice, NR-1 treatment improved corneal wound healing. Furthermore, the expression of markers of corneal epithelium maintenance (DeltaNp63) and CESC proliferation (Bmi-1 and Abcg2) was increased. These effects were mediated by intracellular signalling pathways (Stat3, Erk1/2 and p38). Taken together, our results suggest that NR-1 accelerates the recovery of corneal wounds, and may represent a novel treatment for corneal damage. PMID- 29458291 TI - Local Antibiotic Delivery Systems: Current and Future Applications for Diabetic Foot Infections. AB - Foot infections are common among diabetic patients with peripheral neuropathy and/or peripheral arterial disease, and it can be the pivotal event leading to a minor or major amputation of the lower extremity. Treatment of diabetic foot infections, especially deep-seated ones, remains challenging, in part because impaired blood perfusion and the presence of biofilms can impair the effectiveness of systemic antibiotics. The local application of antibiotics is an emerging field in the treatment of diabetic foot infections, with demonstrable advantages. These include delivery of high concentrations of antibiotics in the affected area, limited systemic absorption, and thus negligible side effects. Biodegradable vehicles, such as calcium sulfate beads, are the prototypical system, providing a good elution profile and the ability to be impregnated with a variety of antibiotics. These have largely superseded the nonbiodegradable vehicles, but the strongest evidence available is for calcium bead implantation for osteomyelitis management. Natural polymers, such as collagen sponge, are an emerging class of delivery systems, although thus far, data on diabetic foot infections are limited. There is recent interest in the novel antimicrobial peptide pexiganan in the form of cream, which is active against most of the microorganisms isolated in diabetic foot infections. These are promising developments, but randomized trials are required to ascertain the efficacy of these systems and to define the indications for their use. Currently, the role of topical antibiotic agents in treating diabetic foot infections is limited and outside of routine practice. PMID- 29458292 TI - Role of Coping Responses in the Relationship Between Perceived Stress and Psychological Well-Being in a Sample of Spanish Educational Teacher Students. AB - Stress in teacher education students is a key issue, due to its physical and social impact and its relevance to students' future as professionals. This study uses the Perceived Stress Scale, the Coping Responses Inventory-Adult Form, and the Psychological Well-Being Scale to analyze how coping strategies mediate the relationship between stress and well-being in a sample of Spanish teacher education students (n = 334). The results show that the students had a good general level of psychological well-being, although with little personal growth and autonomy. Their level of stress meant that they could offer active, engaged responses, although the coping strategies that were used tended to be avoidance type, which could lead to certain adaptive difficulties. Our results also indicate that coping has a partial mediating role. Finally, organizational actions are proposed for universities that could help to enhance students' personal resources for dealing with stress. PMID- 29458293 TI - Endoscopic mucosal resection of non-ampullary sporadic duodenal adenomas: a retrospective analysis with long-term follow-up. AB - OBJECTIVE: We investigate the efficiency of endoscopic mucosal resection (EMR) of non-ampullary sporadic duodenal adenomas (NASDA) in a retrospective analysis with long-term follow-up. METHODS: Consecutive patients undergoing EMR of NASDA between May 2002 and December 2016 were retrospectively identified from an electronic database. Endoscopic follow-up was scheduled after 3, 6 and 12 months for the first year, then yearly for up to five years. RESULTS: EMR of 75 NASDA was performed in 68 patients (56% en-bloc, 44% piecemeal). Retroperitoneal perforations occurred in 3/68 (4.4%) patients, were treated by surgical (n = 2) or percutaneous (n = 1) drainage; delayed bleeding was reported in 13/75 (17.3%) resections and was successfully managed by endoscopy (n = 12) or radiologic embolization (n = 1). There was no procedure-related mortality. Follow-up was available in 61/68 patients (89.7%) after a median time of 59 months from resection. Residual and recurrent adenoma were diagnosed in 9 (14.5%) and 6 (10.9%) cases, respectively; all but one were successfully retreated endoscopically. CONCLUSIONS: EMR for NASDA is effective with a favorable long term outcome. Local recurrences can be retreated endoscopically. A recall system, patient's compliance to endoscopic follow-up are mandatory to detect recurrences and their prompt treatment. PMID- 29458294 TI - The Impact of Implementing an Intensivist Model With Nighttime In-Hospital Nocturnist and Effect on ICU Outcomes. AB - BACKGROUND: Various intensivist staffing models have been suggested, but the long term sustainability and outcomes vary and may not be sustained. We examined the impact of implementing a high-intensity intensivist coverage model with a nighttime in-house nocturnist (non-intensivist) and its effect on intensive care unit (ICU) outcomes. METHODS: We obtained historical control baseline data from 2007 to 2011 and compared the same data from 2011 to 2015. The Acute Physiological and Chronic Health Evaluation outcomes system was utilized to collect clinical, physiological, and outcome data on all adult patients in the medical ICU and to provide severity-adjusted outcome predictions. The model consists of a mandatory in-house daytime intensivist service that leads multidisciplinary rounds, and an in-house nighttime coverage is provided by nocturnist (nonintensivists) with current procedural skills in airways management, vascular access, and commitment to supervise house staff as needed. The intensivist continues to be available remotely at nighttime for house staff and consultation with the nocturnist. A backup intensivist is available for surge management. RESULTS: First year yielded improved throughput (2428 patients/year to 2627 then 2724 at fifth year). Case mix stable at 53.7 versus 55.2. The ICU length of stay decreased from 4.7 days (predicted 4.25 days) to 3.8 days (4.15) in first year; second year: 3.63 days (4.29 days); third year: 3.24 days (4.37), fourth year: 3.34 days (4.45), and fifth year: 3.61 days (4.42). Intensive care unit <24 hours readmission remained at 1%; >24 hours increased from 4% to 6%. Low risk monitoring admissions remained at an average 17% (benchmark 17.18%). Intensive care unit mortality improved with standardized mortality ration averaging at 0.84. Resident satisfaction surveys improved. CONCLUSIONS: Implementing an intensivist service with nighttime nocturnist staffing in a high intensity large teaching hospital is feasible and improved ICU outcomes in a sustained manner that persisted after the initial implementation phase. The model resulted in reduced and sustained observed-to-predicted length of ICU stay. PMID- 29458295 TI - Loneliness in Men 60 Years and Over: The Association With Purpose in Life. AB - Loneliness as a consequence of getting older negatively impacts on the health and well-being of men as they age. Having a purpose in life may mitigate loneliness and therefore positively impact on health and well-being. Limited research into loneliness and purpose in life has been undertaken in older men. This study seeks to understand the relationship between loneliness and purpose in life in a group of older men. Using data from a cross-sectional survey of 614 men aged 60 years and over living in New Zealand, bivariate and multivariate analyses were undertaken to examine the relationship between loneliness and purpose in life using a range of demographic, health, and social connection variables. Bivariate analysis revealed that being unpartnered and having low socioeconomic status, limited social networks, low levels of participation, and mental health issues were associated with loneliness. Multivariate analysis showed that having poor mental health and lower purpose in life were indicators of loneliness. Consequently, improving mental health and purpose in life are likely to reduce loneliness in at-risk older men. As older men are a heterogeneous group from a variety of sociocultural and ethnic backgrounds, a multidimensional approach to any intervention initiatives needs to occur. PMID- 29458296 TI - A non-hydrocephalic goat experimental model to evaluate a ventriculosinus shunt. AB - The ventriculosinus shunt is a promising treatment for hydrocephalus. Currently, different shunt techniques exist, and it is not clear whether one is preferable. This pilot study reports on a non-hydrocephalic goat model (Saanen breed) that provides opportunities to evaluate and optimize several aspects of the ventriculosinus shunt technique. Analysis of the coagulation properties of 14 goats by a viscoelastic coagulation monitor showed that goats have a hypercoagulable state compared to humans. This property can be partially counteracted by antiplatelet drugs. During implantation of a ventriculosinus shunt, a pulsatile reflux of blood was observed. After implantation, the animals recovered to their preoperative state, and none of them developed a superior sagittal sinus thrombosis. Evaluation of the shunts after 16 days showed an obstructing luminal clot. Several model-related factors may have promoted this obstruction: the absence of hydrocephalus, the hypercoagulability of caprine blood and the smaller dimensions of the caprine superior sagittal sinus. However, the pulsatile reflux of blood, which is caused by the compliance of the shunt system distal to the valve, may have been an important factor as well. In conclusion, the non-hydrocephalic goat model limits animal suffering and simplifies the study protocol. This model allows researchers to evaluate their implantation technique and shunt hardware but not the efficacy of the treatment or shunt survival. PMID- 29458297 TI - (R)-fluoxetine enhances cognitive flexibility and hippocampal cell proliferation in mice. AB - Fluoxetine is a clinically successful antidepressant. It is a racemic mixture of (R) and (S) stereoisomers. In preclinical studies, chronic treatment with fluoxetine (10 mg/kg) had antidepressant effects correlated with increased hippocampal cell proliferation in adult rodents. However, the contribution of the enantiomers of fluoxetine is largely unknown. We investigated the effects of treatment with (R)- and (S)-fluoxetine on cognitive behavioral paradigms and examined cell proliferation in the hippocampus of C57BL/6J female mice. In a behavioral sequencing task using the IntelliCage system in which discriminated spatial patterns of rewarded and never-rewarded corners were reversed serially, (R)-fluoxetine-treated mice showed rapid acquisition of behavioral sequencing (compared with S-fluoxetine) and cognitive flexibility in subsequent reversal stages in intra- and inter-session analysis. (R)-fluoxetine also increased cell proliferation in the hippocampus, in particular in the suprapyramidal blade of the dentate gyrus. (R)-fluoxetine had superior effects to (S)-fluoxetine in elevated plus maze, forced-swim and tail-suspension tests. These results suggest that (R)-fluoxetine, which has been reported to have a shorter half-life than (S) fluoxetine, has superior antidepressant effects and more consistently improves spatial learning and memory. This profile offers advantages in depression treatment and may also aid management of the neurocognitive impairments associated with depression. PMID- 29458299 TI - The feasibility and effectiveness of using prism adaptation to treat motor and spatial dysfunction in stroke survivors with multiple incidents of stroke. AB - Background Strokes resulting in cognitive and motor problems can be debilitating and prolong recovery. Risk of a second stroke occurs for 40% of all first-time stroke survivors within five years. Prism adaptation treatment (PAT) may simultaneously improve functions of both spatial and motor systems. This has not been studied with a cohort comprised of multiple strokes nor measured change using specific motor outcomes. Objectives To determine the feasibility and effectiveness of using PAT to improve spatial and motor functions in stroke survivors with multiple strokes. Method A prospective intervention with retrospective comparison. Thirteen participants from an inpatient rehabilitation facility (IRF) comprised the treatment group; 13 others who only received standard care comprised the comparison group. Treatment group tested on: 4 motor and 3 spatial outcome measures before and after the 10 PAT sessions. The comparison group tested on: 1 motor and 3 spatial measures before and after standard care. Results Thirteen participants successfully completed the PAT. Both groups improved on measures of spatial neglect over time (p < .001), but the treatment group showed greater improvement on two subtests of spatial function (Behavior inattention test) (p = .001 & p = .002). Similarly, both groups improved in motor function (Functional independence measure) (p < .001), although the treatment group's improvement was not statistically significant against the comparison group (p = .853). Conclusion PAT is a feasible treatment for stroke survivors with multiple strokes. PAT did improve spatial neglect function more than standard care, only at one level of analysis of standard paper and pencil measures. Further research is necessary. PMID- 29458298 TI - beta-amyloid inhibits hippocampal LTP through TNFR/IKK/NF-kappaB pathway. AB - Objective The suppressive action of the acute application of oligomeric amyloid beta (Abeta) on hippocampal long-term potentiation (LTP) has been reported widely. Many mechanisms have been proposed for Abeta inhibited LTP induction. The inflammatory cytokine tumor necrosis factor-alpha (TNF-alpha) has also been reported to play a key role in this LTP inhibition through Abeta. However, the underlying molecular mechanisms are largely unknown. This study aimed to investigate the link between Abeta- and TNF-alpha-mediated hippocampal LTP inhibition. Methods Acute hippocampal slices of male wildtype or Alzheimer's disease (AD) transgenic mouse models were treated with the inhibitors of either TNF-alpha, IkappaB Kinase (IKK) or Nuclear Factor-kappaB (NF-kappaB) in the presence or absence of oligomeric Abeta42 (500 nM/2 h). The LTP was assessed using field excitatory post synaptic potential recordings (fEPSP), and immunoblotting was used to evaluate the expression of IKK and NF-kappaB. Results Acute treatment with Abeta or TNF-alpha alone inhibited LTP and increased the phosphorylation of IKK and NF-kappaB in wild type mouse hippocampal slices. Pretreatment with TNF-alpha antagonist infliximab rescued the LTP impairment by Abeta and also restored the levels of IKK and NF-kappaB to the control levels. In addition, pretreatment with IKK2 IV or JSH23 also restored the Abeta-mediated LTP impairment. Furthermore, AD transgenic mouse hippocampal slices treated with infliximab or inhibitors of IKK or NF-kappaB showed improved LTP and reversed the activation of IKK and NF-kappaB. Conclusion In conclusion, our observations suggest that the IKK/NF-kappaB signaling pathway play an important role in Abeta mediated hippocampal LTP impairment. Abeta might modulate IKK/NF-kappaB activity by binding or activating tumor necrosis factor receptor (TNFR). PMID- 29458300 TI - Ascaris lumbricoides: challenges in diagnosis, treatment and prevention strategies in a European refugee camp. AB - OBJECTIVES: The roundworm Ascaris lumbricoides is one of the most prevalent parasites belonging to the class of the soil-transmitted helminths. Infections are most common in developing countries with a tropical climate where sanitation and hygiene are poor. However, prevalence of ascariasis in industrialized countries is increasing because of immigration and increasing number of refugees. METHODS: We report a case of ascariasis in a female patient who was admitted to our hospital after she had left the informal refugee camp of Calais in the north of France. RESULTS: After colonoscopic removal of the worm and treatment with mebendazole during three days the patient's symptoms had completely resolved. Medical treatment with benzimidazole derivatives is easy and inexpensive. To prevent parasitic infections in larger populations, mass drug administration should be repeated periodically and must be implemented along with additional measures such as improvements to water, sanitation and hygiene (WASH). These WASH programs have been proven to be highly effective, but access and follow-up are expensive and very difficult to organize in refugee camps, even in wealthy, industrialized countries. CONCLUSIONS: Despite being an old, well-known parasitic disease, ascariasis might reappear in certain populations at risk in industrialized countries. Detection, treatment and follow-up of these patients, and the organization of preventive measures remain challenging. PMID- 29458301 TI - Measurement of peripheral blood flow in patients with peripheral artery disease: Methods and considerations. AB - Peripheral artery disease (PAD) is a manifestation of generalized atherosclerosis which results in hemodynamic compromise of oxygen and substrate delivery to the lower extremity skeletal muscles. Hemodynamic assessments are vital in PAD diagnosis and in the evaluation of strategies aimed at treating claudication (i.e. exercise training, revascularization, and pharmacological agents). Venous occlusion plethysmography (VOP) is a century-old, non-invasive technique used to quantify limb blood flow and has been used to evaluate hemodynamic compromise in patients with PAD. However, the literature suggests a wide array of methodological variability in the measurement and analysis of limb blood flow using VOP. In this manuscript, we overview the clinical application of VOP measurement, and secondly we review the methodological variation that occurs during the measurement and analysis of VOP in healthy individuals and in patients with claudication. PMID- 29458302 TI - Spectroscopic and computational approaches to unravel the mode of binding between a isoflavone, biochanin-A and calf thymus DNA. AB - In the present study, attempt was made to explore the interaction between biochanin-A (BioA) and calf thymus DNA (ctDNA) by employing fluorescence spectroscopy, absorption spectroscopy, circular dichroism (CD), DNA melting studies, viscosity measurements, and molecular modeling methods. A well-known fluorescence probe, acridine orange (AO) was used in the present study in order to enhance the emission intensity of weakly fluorescent ctDNA. Quenching in emission intensity of ctDNA-AO system was observed in the presence of different concentrations of BioA, suggesting that BioA has interacted with ctDNA. The hyperchromic effect observed upon the addition of BioA in the absorption spectra of ctDNA-AO without any shift in its absorption maximum revealed that BioA was bound to ctDNA through groove mode of binding. Further the groove mode of binding of BioA to ctDNA was confirmed by DNA melting studies, viscosity measurements, and molecular docking studies. The results of fluorescence measurements that were carried out at different temperature indicated that the BioA has quenched the emission intensity of ctDNA-AO through static mode of quenching mechanism. Thermodynamic parameters revealed that the BioA-ctDNA-AO system was stabilized by van der Waals forces and hydrogen bonding. The effect of binding of BioA on the conformation of ctDNA was examined by circular dichroism studies. PMID- 29458303 TI - Lifestyle behaviour and risk factor control in coronary patients: Belgian results from the cross-sectional EUROASPIRE surveys. AB - OBJECTIVE: The aim of this study was to assess lifestyle behaviour as well as risk factor management across Belgian coronary patients who participated in the cross-sectional European Action on Secondary Prevention through Intervention to Reduce Events (EUROASPIRE) surveys. METHODS: Analyses are based on a series of coronary patients by combining data from the Belgian participants in the EUROASPIRE III (328 patients; in 2006-2007) and EUROASPIRE IV (343 patients; in 2012-2013) surveys. Four hospitals located in the Ghent area participated in the surveys. Patients included in the analyses were >=18 years old and had been hospitalised for a coronary event. Information on cardiovascular risk factors, lifestyle behaviour and medical treatment were obtained. RESULTS: Overall, the proportion of smokers was 11% with 40% persistent smokers. Adequate physical activity levels were reported by 17%, 28% of patients were obese, 47% was central obese and known diabetes was prevalent in 21% of patients. Hypertension was observed in 46% of patients and 20% had a total cholesterol >=5 mmol/L. About 80% had participated in a cardiac rehabilitation programme and the majority of patients were treated with blood pressure (92%) or lipid-lowering drugs (92%). Anxiety and depressive symptoms were reported by 30% and 24%, respectively. Differences between EUROASPIRE III and IV were limited. CONCLUSIONS: Compared to the overall EUROASPIRE results in Europe, Belgian CHD patients seem to do slightly better. However, tackling obesity, physical inactivity, hypertension and psychosocial distress remains an important challenge in the management of coronary patients. PMID- 29458304 TI - Asbestos fiber length and its relation to disease risk. AB - Differences in chemical and crystalline composition, fiber dimension, aerodynamic characteristics and biodurability are among the critical factors that define the toxicological and pathological consequences of asbestos exposure. Specifically, fiber dimension can impact whether the fiber is respired, whether and how deeply it is deposited in the lung, and how efficiently and rapidly it may be cleared. This paper provides a current, comprehensive evaluation of the weight of evidence regarding the relationship between asbestos fiber length and disease potency (for malignant and nonmalignant endpoints). In vitro studies, animal exposure studies and epidemiology data were reviewed. We found that the data reported over the last several decades consistently support the conclusions that exposure to fibers longer than 10 um and perhaps 20 um are required to significantly increase the risk of developing asbestos-related disease in humans and that there is very little, if any, risk associated with exposure to fibers shorter than 5 um. Fiber length as a predictor of potency has been evaluated by several federal agencies in the U.S. and could significantly influence future regulatory decisions for elongated mineral particles (EMPs) and high-aspect ratio nanoparticles (HARNs). PMID- 29458305 TI - Estimating indoor galaxolide concentrations using predictive models based on objective assessments and data about dwelling characteristics. AB - BACKGROUND: Galaxolide (HHCB) is used for fragrance in many consumer products. The aim of the current study was to use objective assessments of HHCB to build a predictive model in order to estimate indoor-measured HHCB concentrations from questionnaire-based data on dwelling characteristics and occupants' habits and activities. METHODS: Environmental assessments of indoor HHCB, dwelling characteristics were carried out in 150 dwellings in Brittany (France). Among the various models that were tested, the best predictive model for the reduced set of characteristics was identified on the basis of the coefficient of determination (R2) criterion. RESULTS: Linear regression model showed among the best performances (R2 = 0.48), together with some more complex models. According to the estimated results, the main variables that significantly increased HHCB concentrations were: living in rural area, drying clothes inside dwellings, painted walls, chipboard furniture, double glazing, damaged floors and duration of bathroom door being kept open. Laminated floors and presence of indoor plants were found to significantly decrease HHCB concentrations. DISCUSSION: The linear model based on objective assessments and questionnaire-derived data about dwelling characteristics and occupants' activities constituted an easy method for predicting indoor air HHCB concentrations. For studies including a large number of dwellings, modeling of HHCB concentrations is cheaper than measuring it in every location. Our methodological procedure can be applied to other indoor air pollutants. PMID- 29458306 TI - A mechanistic review of particle overload by titanium dioxide. AB - Chronic exposure to titanium dioxide (TiO2) induces slight but significant pulmonary inflammation in experimental animals, and among potential mechanisms, particle overload is likely. Although mechanisms of particle overload are poorly understood, excess accumulation of dust particles in dust containing macrophages (dust cells) can impair their mobility, resulting in reduced clearance ability. Accordingly, retention half-times of inhaled TiO2 increase linearly with lung burden in rodents, and mathematical (Michaelis-Menten-like) models for pulmonary clearance rates of TiO2 as a function of lung burden have suggested an alternative mechanism for particle overload, involving excess accumulation of macrophages in the translocation pathway due to the narrow exit to the ciliated airway region, and leading to reduced pulmonary TiO2 clearance rates. This mechanism is consistent with observations showing that TiO2 retention half-times in the lungs of rats and mice show no change from the initial value until the lung burden exceeds around mass burden of 3 mg or surface area burden of 1000 cm2. In addition, excess accumulation of macrophages is consistent with several particle overload-associated pathological changes, including accelerated neutrophilic inflammation, elevation of lymph node burden, and epithelial cell hyperplasia. Because excessive alveolar accumulation of macrophages may accelerate interstitialization of macrophages (including dust cells) and subsequent migration into lymph nodes, alveolar macrophages and dust cells likely migrate into interstitial spaces and escape to the luminal side of the ciliated airway region. PMID- 29458307 TI - Influence of environmental tobacco smoke on morphology and functions of cardiovascular system assessed using diagnostic imaging. AB - Exposure to tobacco smoke is a significant problem of environmental medicine. Tobacco smoke contains over one thousand identified chemicals including numerous toxicants. Cardiovascular system diseases are the major cause of general mortality. The recent development of diagnostic imaging provided methods which enable faster and more precise diagnosis of numerous diseases, also those of cardiovascular system. This paper reviews the most significant scientific research concerning relationship between environmental exposure to tobacco smoke and the morphology and function of cardiovascular system carried out using diagnostic imaging methods, i.e. ultrasonography, angiography, computed tomography and magnetic resonance imaging. In the forthcoming future, the studies using current diagnostic imaging methods should contribute to the reliable documentation, followed by the wide-spreading knowledge of the harmful impact of the environmental tobacco smoke exposure on the cardiovascular system. PMID- 29458308 TI - New findings about the intrascaphoid arterial system. AB - We investigated the intraosseous arteries of six normal cadaveric scaphoids using red lead injection and three-dimensional reconstruction with micro-computed tomography. The arterial entrances were generally located around the dorsal ridge, the insertion of the scaphocapitate ligament and the radial part of the radioscaphocapitate ligament. Two to three trunk arteries entered the scaphoid on dorsal ridge at the level of the waist. The distal part of the scaphoid was mainly supplied by arteries from the waist. The blood supply of about 40% of proximal part of the scaphoid was poor. The blood supply from the scaphoid dorsal ridge plays an important role, not only for the proximal part of the scaphoid, but also for the waist and even the distal pole. The intrascaphoid arterial pattern may be contributory to nonunion, especially in proximal pole fractures. PMID- 29458309 TI - A cyclic testing comparison of two flexor tendon repairs: asymmetric and modified Lim-Tsai techniques. AB - This study compared the biomechanical performance of a novel 6-strand asymmetric flexor tendon repair with the modified Lim-Tsai technique using cyclic testing. Two groups of ten porcine tendons each were repaired and tested. Gap formation at every 100 cycles was measured. Survival was defined as maximum gap formation below 2 mm. All the repairs survived Stage I. With increased cyclic load in Stage II, the mean gap formation of modified Lim-Tsai repairs exceeded 2 mm at the 600th cycle and reached 4.2 mm (SD 1.93) at the end of Stage II, resulting in 0% survival. The mean gap formation of asymmetric repairs reached 2.0 mm (SD 1.43) at the 800th cycle and was 2.4 mm (SD 1.52) at the end of Stage II, with 60% survival. The asymmetric repair has better biomechanical performance under cyclic testing as compared with the modified Lim-Tsai repair. PMID- 29458310 TI - Flexor tendon repair in the hand with the M-Tang technique (without peripheral sutures), pulley division, and early active motion. AB - : We report outcomes in 29 patients with flexor tendon repairs in 32 digits (five thumbs and 27 fingers) with our modified protocols. We repaired the lacerated flexor digitorum profundus tendons with core suture repairs using the 6-strand M Tang method and without circumferential sutures. We divided the pulleys as much as needed to allow excursion of the repaired tendons, including complete division of the A4 or A2 pulleys when necessary. In nine fingers, we repaired one slip of the flexor digitorum superficialis tendon and resected the other half. When the flexor digitorum profundus tendon would not glide under the A2 pulley, we excised the remaining slip of the flexor digitorum superficialis tendon. The wrist was splinted in mild extension post-surgery with early commencement of tenodesis exercises. No tendon repair ruptured. By the Strickland criteria, out of 27 fingers, 18 had excellent, six had good, two had fair, and one had poor results. We conclude that a strong core suture (such as the M-Tang repair) without peripheral sutures, and with division of pulleys as necessary is safe for early active motion and yields good outcomes. LEVEL OF EVIDENCE: IV. PMID- 29458311 TI - Double superior vena cava: presentation of two cases and review of the literature. AB - INTRODUCTION: Various anomalies in the development of the great thoracic veins of the embryo can be incidentally discovered in the normal adult. Duplication of superior vena cava (SVC) is a rare abnormality, but the most common thoracic venous congenital anomaly. Case reports-methods: We present two cases in the intensive care unit of our hospital, of asymptomatic patients who underwent an uneventful central line placement in the left subclavian vein. The track of the catheter, as shown in the X-ray, was misplaced to the left of the aorta and further investigation with computed tomography angiography confirmed a persistent left SVC. In both cases the vein drained into the coronary sinus and then to the right atrium. In the second case the echocardiography revealed a dilated coronary sinus. CONCLUSIONS: Double SVC can be fortuitously discovered during catheter insertion, thoracic or cardiac imaging and surgery. In most cases it drains into the right atrium, through the coronary sinus. This entity is significant to the physician because of its importance in differential diagnosis as a cause of a widened mediastinum, as well as any difficulty that can occur in the placement of a central venous catheter or a pace maker. PMID- 29458312 TI - Reflections on researcher departure: Closure of prison relationships in ethnographic research. AB - BACKGROUND: The United Kingdom has the highest incarceration rate in Western Europe. It is known that women in prison are a vulnerable female population who are at risk of mental ill-health due to disadvantaged and chaotic life experiences. Accurate numbers of pregnant women held in UK prisons are not recorded, yet it is estimated that 6%-7% of the female prison population are at varying stages of pregnancy and around 100 babies are born to incarcerated women each year. There are limited published papers that document the departure of the researcher following closure of fieldwork with women in prison. This article identifies the dilemmas and challenges associated with the closure of prison fieldwork through the interwoven reflections of the researcher. Departure scenarios are presented which illuminate moments of closure talk with five women, supported by participant reflections regarding abandonment and loss, making pledges for the future, self-affirmation, incidental add-ons at the end of an interview and red flags, alerting the researcher to potential participant harm through ill health or self-injury. OBJECTIVES: The primary intention of the study was to observe the pregnant woman's experience with the English prison system through interviews with pregnant women and field observations of the environment. RESEARCH DESIGN: Ethnographic design enabled the researcher, a practising midwife, to engage with the prisoners' pregnancy experiences in three English prisons, which took place over 10 months during 2015-2016. Data collection involved semi-structured, audio-recorded interviews with 28 female prisoners in England who were pregnant or had recently given birth while imprisoned, 10 members of staff and a period of non-participant observation. Follow-up interviews with 5 women were undertaken as their pregnancies progressed. Computerised qualitative data analysis software was used to generate and analyse pregnancy-related themes. Ethical considerations: Favourable ethical opinion was granted by National Offender Management Services through the Health Research Authority Integrated Research Application System and permission to proceed was granted by the University of Hertfordshire, UK. FINDINGS: Thematic analysis enabled the identification of themes associated with the experience of prison pregnancy illuminating how prison life continues with little consideration for their unique physical needs, coping tactics adopted and the way women negotiate entitlements. On researcher departure from the field, the complex feelings of loss and sadness were experienced by both participants and researcher. DISCUSSION: To leave the participant with a sense of abandonment following closure of fieldwork, due to the very nature of the closed environment, risks re enactment of previous emotional pain of separation. Although not an ethical requirement, the researcher sought out psychotherapeutic supervision during the fieldwork phase with 'Janet', a forensic psychotherapist, which helped to highlight the need for careful closure of research/participant relationships with a vulnerable population. This article brings to the consciousness of prison researchers the need to minimise potential harm by carefully negotiating how to exit the field. Reflections of the researcher are interlinked with utterances from some participants to illustrate the types of departure behaviours. CONCLUSION: Closure of fieldwork and subsequent researcher departure involving pregnant women in prison requires careful handling to uphold the ethical research principle 'do no harm'. PMID- 29458313 TI - How to succeed with ethics reflection groups in community healthcare? Professionals' perceptions. AB - BACKGROUND: Healthcare personnel in the municipal healthcare systems experience many ethical challenges in their everyday work. In Norway, 243 municipalities participated in a national ethics project, aimed to increase ethical competence in municipal healthcare services. In this study, we wanted to map out what participants in ethics reflection groups experienced as promoters or as barriers to successful reflection. OBJECTIVES: To examine what the staff experience as promoters or as barriers to successful ethics reflection. RESEARCH DESIGN: The study has a qualitative design, where 56 participants in municipal healthcare participated in 10 different focus-group interviews. Ethical considerations: The data collection was based on the participants' informed consent and approved by the Data Protection Official of the Norwegian Centre for Research Data. RESULTS: The informants had different experiences from ethics reflection group. Nevertheless, we found that there were several factors that were consistently mentioned: competence, facilitator's role, ethics reflection groups organizing, and organizational support were all experienced as promoters and as a significant effect on ethics reflection groups. The absence of such factors would constitute important barriers to successful ethics reflection. DISCUSSION: The results are coincident with other studies, and indicate some conditions that may increase the possibility to succeed with ethics reflection groups. A systematic approach seems to be important, the systematics of the actual reflections, but also in the organization of ethics reflection group at the workplace. Community healthcare is characterized by organizational instabilities as many vacancies, high workloads, and lack of predictability. This can be a hinder for ethics reflection group. CONCLUSION: Both internal and external factors seem to influence the organization of ethics reflection group. The municipalities' instabilities challenging this work, and perceived as a clear inhibitor for the development. The participants experienced that the facilitator is the most important success factor for establishing, carrying out, and to succeed with ethics reflection groups. PMID- 29458314 TI - A blended-learning programme regarding professional ethics in physiotherapy students. AB - BACKGROUND: In the university context, assessing students' attitude, knowledge and opinions when applying an innovative methodological approach to teach professional ethics becomes fundamental to know if the used approach is enough motivating for students. RESEARCH OBJECTIVE: To assess the effect of a blended learning model, based on professional ethics and related to clinical practices, on physiotherapy students' attitude, knowledge and opinions towards learning professional ethics. Research design and participants: A simple-blind clinical trial was performed (NLM identifier NCT03241693) (control group, n = 64; experimental group, n = 65). Both groups followed clinical practices for 8 months. Control group performed a public exposition of a clinical case about professional ethics. By contrast, an 8-month blended-learning programme regarding professional ethics was worked out for experimental group. An online syllabus and online activities were elaborated, while face-to-face active participation techniques were performed to discuss ethical issues. Students' attitudes, knowledge and opinions towards learning professional ethics were assessed. Ethical considerations: The study was approved by the University Ethic Committee of Human Research and followed the ethical principles according to the Declaration of Helsinki. FINDINGS: After the programme, attitudes and knowledge towards learning professional ethics of experimental group students significantly improved, while no differences were observed in control group. Moreover, opinions reported an adequate extension of themes and temporization, importance of clinical practices and interest of topics. Case study method and role playing were considered as the most helpful techniques. CONCLUSION: The blended-learning programme proposed, based on professional ethics and related to clinical practices, improves physiotherapy students' attitudes, knowledge and opinions towards learning professional ethics. PMID- 29458315 TI - The disconnect between nutrition guidelines and evidence: how much protein should I prescribe to this critically ill patient? PMID- 29458316 TI - Study protocol for the Augmented versus Routine Approach to Giving Energy Trial (TARGET). AB - BACKGROUND: Nutrition is routinely provided to critically ill patients who are mechanically ventilated and remain in the intensive care unit for more than a few days. Nasogastric feeding, which is standard practice for patients who are unable to tolerate oral nutrition, typically delivers less than 60% of the recommended energy requirements. It remains uncertain whether the delivery of about 100% of the recommended energy goals via the enteral route will affect survival and other important clinical outcomes. OBJECTIVE: To describe the protocol for a large scale, multicentre, double-blind, randomised, controlled, parallelgroup, phase 3 clinical trial to determine if augmentation of calorie delivery using an energy dense enteral nutrition formulation in mechanically ventilated patients increases 90-day survival when compared with routine care. METHODS: 4000 patients who are mechanically ventilated and are expected to receive enteral nutrition for more than 2 days are to be randomised to an energy-dense formulation (1.5 kcal/mL) or routine enteral feed formulation (1 kcal/mL), given at the same rate. The primary outcome is 90-day all-cause mortality. Secondary outcomes include cause-related mortality up to Day 90; all-cause mortality at hospital discharge and at Days 28 and 180 after randomisation; and ventilator-, vasopressorand renal replacement free days to Day 28. Health-related quality of life and functional assessments will be conducted at Day 180 after randomisation. RESULTS AND CONCLUSIONS: The results of this trial are expected to determine whether increased energy delivery, using an energy-dense formula can improve clinically meaningful outcomes, including survival. PMID- 29458317 TI - Statistical analysis plan for the Augmented versus Routine Approach to Giving Energy Trial (TARGET). AB - BACKGROUND: The Augmented versus Routine Approach to Giving Energy Trial (TARGET) is a 4000-patient randomised, double-blind controlled trial designed to evaluate whether enteral delivery of recommended energy goals using a 1.5 kcal/mL enteral nutrition formulation improves clinical outcomes, compared with a 1 kcal/mL enteral nutrition formulation delivered at the same goal rate, in critically ill patients receiving invasive mechanical ventilation. OBJECTIVE: In keeping with best practice, and in accordance with other trials conducted by the investigators, a pre-specified statistical analysis plan has been described and made public before completion of patient recruitment and data collection into the TARGET trial. METHODS: Our statistical analysis plan was designed by the TARGET chief investigators and statisticians and approved by the TARGET Management Committee. We reviewed the data collected as specified in the trial protocol and collected in the case report form. We present information pertaining to data collection, pre-specified subgroups, processes of care and trial outcomes. Primary and secondary outcomes are defined and methods for assessing functional outcomes (secondary outcomes) are described. RESULTS: We have developed a statistical analysis plan that includes our methods for presenting the trial profile, baseline characteristics, processes of care, outcomes and adverse events. Seven pre-specified subgroups and our methods for statistical comparisons between groups are described. CONCLUSION: We have developed a pre-specified statistical analysis plan for TARGET. To minimise analytical bias, this plan has been developed and made available to the public domain before completing recruitment and data collection.

AB - BACKGROUND: The balance of risks and benefits of conservative v standard care oxygen strategies for patients who are invasively ventilated in the intensive care unit (ICU) is uncertain. OBJECTIVE: To describe the study protocol and statistical analysis plan for the ICU randomised trial comparing two approaches to oxygen therapy (ICU-ROX). DESIGN, SETTING AND PARTICIPANTS: Protocol for a multicentre, randomised, participant and outcome assessor-blinded, standard care controlled, parallel-group, two-sided superiority trial to be conducted in up to 22 ICUs in Australia and New Zealand. 1000 adults who are mechanically ventilated in the ICU and expected to remain ventilated beyond the day after recruitment will be randomly assigned to conservative oxygen therapy or standard care in a 1:1 ratio. ICU-ROX began with an internal pilot phase in September 2015. It is anticipated that recruitment will be completed in 2018. MAIN OUTCOME MEASURES: The primary endpoint will be alive, ventilator-free days to Day 28. Secondary outcomes include 90- and 180-day all-cause mortality, survival time to 180 days, and quality of life and cognitive function at 180 days. All analyses will be conducted on an intentionto- treat basis. RESULTS AND CONCLUSIONS: ICU-ROX will compare the effect of conservative v standard oxygen therapy in critically ill mechanically ventilated adults who are expected to be ventilated beyond the day after recruitment on ventilatorfree days to Day 28.

PMID- 29458319 TI - Proportional assist ventilation versus pressure support ventilation in weaning ventilation: a pilot randomised controlled trial. AB - OBJECTIVE: Proportional assist ventilation with load-adjustable gain factors (PAV+) is a mode of ventilation that provides assistance in proportion to patient effort. This may have physiological and clinical advantages when compared with pressure support ventilation (PSV). Our objective was to compare these two modes in patients being weaned from mechanical ventilation. DESIGN: Prospective randomised controlled trial comparing PSV with PAV+. SETTING: University affiliated, tertiary referral intensive care unit (ICU). PARTICIPANTS: Mechanically ventilated patients on a controlled mode of ventilation for at least 24 hours, who were anticipated to be spontaneously ventilated for at least 48 hours after randomisation. INTERVENTIONS: Nil. MAIN OUTCOME MEASURES: The primary outcome was time to successful liberation from the ventilator after the commencement of a spontaneous mode of ventilation. Secondary outcomes were requirement of rescue (mandatory) ventilation, requirement of sedative drugs, requirement for tracheostomy, re-intubation within 48 hours of extubation, ICU length of stay (LOS), hospital LOS, and ICU and hospital mortality. RESULTS: 50 patients were randomised to either PSV (n = 25) or PAV+ (n = 25). There was no significant difference between the PAV+ and PSV groups in time to successful weaning (84.3 v 135.9 hours, respectively; P = 0.536). Four patients randomised to PAV+ were crossed over to PSV during weaning. There was no significant difference between groups for rescue ventilation, reintubation within 48 hours, tracheostomy, sedatives and analgesics prescribed, and ICU and hospital LOS. ICU mortality was higher in the PSV group (25% v 4 %; P = 0.002). CONCLUSIONS: Both modes of ventilation were comparable in time to liberation from the ventilator. PMID- 29458320 TI - Evaluation of urea and creatinine change during continuous renal replacement therapy: effect of blood flow rate. AB - OBJECTIVE: To determine if faster blood flow rate (BFR) has an effect on solute maintenance in continuous renal replacement therapy. DESIGN: Prospective randomised controlled trial. SETTING: 24-bed, single centre, tertiary level intensive care unit. PARTICIPANTS: Critically ill adults requiring continuous renal replacement therapy (CRRT). INTERVENTIONS: Patients were randomised to receive one of two BFRs: 150 mL/min or 250 mL/min. MAIN OUTCOME MEASURES: Changes in urea and creatinine concentrations (percentage change from baseline) and delivered treatment for each 12-hour period were used to assess solute maintenance. RESULTS: 100 patients were randomised, with 96 completing the study (49 patients, 150 mL/min; 47 patients, 250 mL/min). There were a total of 854 12 hour periods (421 periods, 150 mL/min; 433 periods, 250 mL/ min). Mean hours of treatment per 12 hours was 6.3 hours (standard deviation [SD], 3.7) in the 150 mL/min group, and 6.7 hours (SD, 3.9) in the 250 mL/min group (P = 0.6). There was no difference between the two BFR groups for change in mean urea concentration (150 mL/min group, -0.06%; SD, 0.015; v 250 mL/min group, -0.07%; SD, 0.01; P = 0.42) or change in mean creatinine concentration (150 mL/min, 0.05%; SD, 0.01; v 250 mL/min, -0.08%; SD, 0.01; P = 0.18). Independent variables associated with a reduced percentage change in mean serum urea and creatinine concentrations were low haemoglobin levels (-0.01%; SD, 0.005; P = 0.002; and 0.01%; SD, 0.005; P = 0.006, respectively) and less hours treated (-0.023%; SD, 0.001; P = 0.000; and -0.02%; SD, 0.002; P = 0.001, respectively). No effect for bodyweight was found. CONCLUSIONS: Faster BFR did not affect solute control in patients receiving CRRT; however, differences in urea and creatinine concentrations were influenced by serum haemoglobin and hours of treatment. PMID- 29458321 TI - Differential effects of isotonic and hypotonic 4% albumin solution on intracranial pressure and renal perfusion and function. AB - OBJECTIVES: Albumin is used to resuscitate trauma patients but may increase intracranial pressure (ICP). Its effects on renal blood flow and function are unknown. Our aim was to examine the effects of hypertonic albumin on ICP and renal function, and if any effects are due to the hypotonicity of the solution containing albumin or to albumin itself. DESIGN, SETTING AND SUBJECTS: Cross over, randomised controlled experimental study of six adult Merino ewes in the animal facility of a research institute. METHOD: Sheep were implanted with flow probes around the pulmonary and renal arteries and an ICP monitoring catheter in a lateral cerebral ventricle. Conscious sheep received normal saline, commercially available hypotonic 4% albumin solution (4% Albumex [278 mOsm/kg]) or a novel isotonic 4% albumin solution (288 mOsm/kg), with at least 48 hours between each intervention. RESULTS: Commercial hypotonic albumin solution increased ICP (by 8.5 mmHg [SEM, 2.1 mmHg]; P < 0.01), but neither isotonic albumin solution nor saline significantly changed ICP. The increase in ICP with hypotonic albumin solution was associated with an increase in central venous pressure (CVP) (by 5.4 mmHg [SEM, 0.6 mmHg]; P < 0.001), but no significant changes in cardiac output or stroke volume. None of the infusions changed renal blood flow, plasma creatinine level, creatinine clearance or plasma or urinary electrolyte levels. CONCLUSION: Compared with saline or isotonic albumin solution, hypotonic albumin solution increased ICP and CVP, but did not alter arterial pressure, cardiac output renal blood flow or renal function. Our findings support the view that the tonicity of the albumin solution, rather than the albumin itself, is responsible for increasing ICP. PMID- 29458322 TI - Predicting recovery from acute kidney injury in critically ill patients: development and validation of a prediction model. AB - OBJECTIVE: Intensive care unit (ICU) patients with acute kidney injury (AKI) who recover kidney function within 28 days experience less severe chronic kidney impairment and have increased long term survival. The aims of this study were to develop and validate a risk prediction model to identify these patients. DESIGN: Observational study with development and validation of a risk prediction model. SETTING: Nine academic ICUs in Denmark. PARTICIPANTS: Development cohort of critically ill patients with AKI at ICU admission from the Procalcitonin and Survival Study cohort (n = 568), validation cohort of adult patients with AKI admitted to two university hospitals in Denmark in 2012-13 (n = 766). INTERVENTIONS: None. MAIN OUTCOME MEASURES: Recovery of kidney function was defined as living for 5 consecutive days with no renal replacement therapy and with creatinine plasma levels below 1.5-fold the levels determined before ICU admission. RESULTS: A total of 266 patients (46.8%) recovered prior kidney function in the development cohort, and 453 patients (59.1%) in the validation cohort. The prediction model included elevation in creatinine, urinary output, sex and age. In the validation cohort, 69 patients (9.0%) had a predicted chance of recovery < 25%, and their observed rate of recovery was 21.5%. This observed rate of recovery was 81.7% among the 325 patients who had a predicted chance > 75%. The area under the receiver operations curves for predicting recovery in the validation cohort was 73.1%. CONCLUSION: We constructed and validated a simple model that can predict the chance of recovery from AKI in critically ill patients. PMID- 29458323 TI - A randomised controlled trial to determine the effectiveness of a radial arterial catheter dressing. AB - OBJECTIVE: To reduce radial arterial catheter failure in patients admitted to an adult intensive care unit (ICU). DESIGN: A randomised controlled trial. SETTING: A single site, large metropolitan tertiary referral public hospital. PARTICIPANTS: Three hundred participants admitted to an adult ICU were enrolled between 25 May and 13 September 2015. INTERVENTIONS: Participants were randomly assigned to one of two treatment groups (a polyurethane adhesive keyhole dressing or a polyurethane adhesive keyhole dressing together with a polyurethane semipermeable transparent dressing). MAIN OUTCOME MEASURE: Arterial catheter failure. RESULTS: Data were complete for 289 of the 300 adult participants, who were randomised to one of the two groups. There were 179 men (62%) with a median age of 61 years (IQR, 48-74). Overall, there were 109 arterial catheter failures (38%). There was a significantly higher catheter failure rate in the usual care group (65, 60%) compared with the intervention group (44, 40%; P = 0.05). Accidental catheter removal occurred in 87% of cases (n = 27) in the usual care group and in 13% of cases (n = 4) in the intervention group (P = 0.05). There was no significant difference between the two groups for time to catheter failure (P = 0.06). However, if patients were sedated, they were 54% less likely to experience arterial catheter failure (OR, 0.46; 95% CI, 0.31-0.67; P < 0.0001). CONCLUSION: This study showed a statistically significant reduction in arterial catheter failure using a radial arterial catheter dressing of a polyurethane adhesive keyhole dressing together with a polyurethane semipermeable transparent dressing. The nursing care technique of applying this dressing may improve dressing efficacy and patient safety and reduced costs. PMID- 29458324 TI - Smoking cessation therapy in Australian and New Zealand intensive care units: a multicentre point prevalence study. AB - OBJECTIVE: To obtain an accurate estimate of smoking prevalence and smoking cessation support practices, including nicotine replacement therapy (NRT), in Australian and New Zealand intensive care units (ICUs). DESIGN, SETTING AND PARTICIPANTS: Cross-sectional, observational study using data obtained from adult ICUs participating in the Australian and New Zealand Intensive Care Society Clinical Trials Group Point Prevalence Program in 2016. MAIN OUTCOME MEASURES: Prevalence and intensity of current smoking, baseline characteristics of smokers in comparison with non-smokers and frequency of NRT use while admitted to the ICU. RESULTS: Smoking data were present for 551 of 671 adult ICU patients from 47 ICUs on 2 study days in 2016. Of these 551 patients, 112 were current smokers (20.3%; 95% CI, 17.0-23.9%). No significant differences in severity of illness or mortality were observed between smokers and non-smokers. NRT was prescribed to 30/112 smokers (26.8%), and in 28 of those 30 patients (93%) it was administered via nicotine patch alone. Routine prescribing of NRT was practised in 28/47 ICUs (60%), and 24/47 ICUs (51%) had formal protocols or guidelines in place related to supporting smoking cessation. CONCLUSIONS: The prevalence of smoking in Australian and New Zealand ICUs patients is high. Over half of participating ICUs reported the routine prescription of NRT despite uncertainty regarding the practice. Further research evaluating the safety and efficacy of NRT is required.

PMID- 29458326 TI - Global study of holistic morphological effectors in the budding yeast Saccharomyces cerevisiae. AB - BACKGROUND: The size of the phenotypic effect of a gene has been thoroughly investigated in terms of fitness and specific morphological traits in the budding yeast Saccharomyces cerevisiae, but little is known about gross morphological abnormalities. RESULTS: We identified 1126 holistic morphological effectors that cause severe gross morphological abnormality when deleted, and 2241 specific morphological effectors with weak holistic effects but distinctive effects on yeast morphology. Holistic effectors fell into many gene function categories and acted as network hubs, affecting a large number of morphological traits, interacting with a large number of genes, and facilitating high protein expression. Holistic morphological abnormality was useful for estimating the importance of a gene to morphology. The contribution of gene importance to fitness and morphology could be used to efficiently classify genes into functional groups. CONCLUSION: Holistic morphological abnormality can be used as a reproducible and reliable gene feature for high-dimensional morphological phenotyping. It can be used in many functional genomic applications. PMID- 29458328 TI - Dynamics of promoter bivalency and RNAP II pausing in mouse stem and differentiated cells. AB - BACKGROUND: Mammalian embryonic stem cells display a unique epigenetic and transcriptional state to facilitate pluripotency by maintaining lineage specification genes in a poised state. Two epigenetic and transcription processes involved in maintaining poised state are bivalent chromatin, characterized by the simultaneous presence of activating and repressive histone methylation marks, and RNA polymerase II (RNAPII) promoter proximal pausing. However, the dynamics of histone modifications and RNAPII at promoters in diverse cellular contexts remains underexplored. RESULTS: We collected genome wide data for bivalent chromatin marks H3K4me3 and H3K27me3, and RNAPII (8WG16) occupancy together with expression profiling in eight different cell types, including ESCs, in mouse. The epigenetic and transcription profiles at promoters grouped in over thirty clusters with distinct functional identities and transcription control. CONCLUSION: The clustering analysis identified distinct bivalent clusters where genes in one cluster retained bivalency across cell types while in the other were mostly cell type specific, but neither showed a high RNAPII pausing. We noted that RNAPII pausing is more associated with active genes than bivalent genes in a cell type, and was globally reduced in differentiated cell types compared to multipotent. PMID- 29458327 TI - Histone modification profiling in breast cancer cell lines highlights commonalities and differences among subtypes. AB - BACKGROUND: Epigenetic regulators are frequently mutated or aberrantly expressed in a variety of cancers, leading to altered transcription states that result in changes in cell identity, behavior, and response to therapy. RESULTS: To define alterations in epigenetic landscapes in breast cancers, we profiled the distributions of 8 key histone modifications by ChIP-Seq, as well as primary (GRO seq) and steady state (RNA-Seq) transcriptomes, across 13 distinct cell lines that represent 5 molecular subtypes of breast cancer and immortalized human mammary epithelial cells. DISCUSSION: Using combinatorial patterns of distinct histone modification signals, we defined subtype-specific chromatin signatures to nominate potential biomarkers. This approach identified AFAP1-AS1 as a triple negative breast cancer-specific gene associated with cell proliferation and epithelial-mesenchymal-transition. In addition, our chromatin mapping data in basal TNBC cell lines are consistent with gene expression patterns in TCGA that indicate decreased activity of the androgen receptor pathway but increased activity of the vitamin D biosynthesis pathway. CONCLUSIONS: Together, these datasets provide a comprehensive resource for histone modification profiles that define epigenetic landscapes and reveal key chromatin signatures in breast cancer cell line subtypes with potential to identify novel and actionable targets for treatment. PMID- 29458329 TI - Mouse chromocenters DNA content: sequencing and in silico analysis. AB - BACKGROUND: Chromocenters are defined as a punctate condensed blocks of chromatin in the interphase cell nuclei of certain cell types with unknown biological significance. In recent years a progress in revealing of chromocenters protein content has been made although the details of DNA content within constitutive heterochromatin still remain unclear. It is known that these regions are enriched in tandem repeats (TR) and transposable elements. Quick improvement of genome sequencing does not help to assemble the heterochromatic regions due to lack of appropriate bioinformatics techniques. RESULTS: Chromocenters DNA have been isolated by a biochemical approach from mouse liver cells nuclei and sequenced on the Illumina MiSeq resulting in ChrmC dataset. Analysis of ChrmC dataset by the bioinformatics tools available revealed that the major component of chromocenter DNA are TRs: ~ 66% MaSat and ~ 4% MiSat. Other previously classified TR families constitute ~ 1% of ChrmC dataset. About 6% of chromocenters DNA are mostly unannotated sequences. In the contigs assembled with IDBA_UD there are many fragments of heterochromatic Y-chromosome, rDNA and other pseudo-genes and non coding DNA. A protein coding sfi1 homolog gene fragment was also found in contigs. The Sfi1 homolog gene is located on the chromosome 11 in the reference genome very close to the Golden Pass Gap (a ~ 3 Mb empty region reserved to the pericentromeric region) and proves the purity of chromocenters isolation. The second major fraction are non-LTR retroposons (SINE and LINE) with overwhelming majority of LINE - ~ 11% of ChrmC. Most of the LINE fragments are from the ~ 2 kb region at the end of the 2nd ORF and its' flanking region. The precise LINEs' segment of ~ 2 kb is the necessary mouse constitutive heterohromatin component together with TR. The third most abundant fraction are ERVs. The ERV distribution in chromocenters differs from the whole genome: IAP (ERV2 class) is the most numerous in ChrmC while MaLR (ERV3 class) prevails in the reference genome. IAP and its LTR also prevail in TR containing contigs extracted from the WGS dataset. In silico prediction of IAP and LINE fragments in chromocenters was confirmed by direct fluorescent in situ hybridization (FISH). CONCLUSION: Our data of chromocenters' DNA (ChrmC) sequencing demonstrate that IAP with LTR and a precise ~ 2 kb fragment of LINE represent a substantial fraction of mouse chromocenters (constitutive heteroshromatin) along with TRs. PMID- 29458330 TI - Gait pattern in patients with peripheral artery disease. AB - BACKGROUND: The aim of the present paper is to assess the gait pattern of patients with Peripheral Artery Disease (PAD). A more specific aim is to compare the gait pattern of PAD patients before and after the appearance of intermittent claudication symptoms. METHODS: The study involved 34 PAD patients with a claudication distance >=200 m and 20 participants without PAD, who formed the control group. The gait pattern of PAD patients was assessed twice: before the appearance of intermittent claudication symptoms (pain-free conditions) and after the appearance of intermittent claudication symptoms (pain conditions). RESULTS: Compared to the control group, PAD patients presented a statistically significant decrease in step length both during pain-free conditions (52.6 +/- 12.5 vs. 72.8 +/- 18.5 cm, p = 0.008) and in pain conditions (53.3 +/- 13.3 vs. 72.8 +/- 18.5 cm, p = 0.006). As for the remaining spatiotemporal parameters, there were no differences observed between the patient group and the controls. Intermittent claudication symptom induced by the walking test on the treadmill did not bring about any new abnormalities in the gait pattern or intensify the existing abnormalities of the gait. CONCLUSIONS: PAD patients have a tendency to shorten their step length regardless of the presence of intermittent claudication.

PMID- 29458333 TI - Pre-anesthetic assessment with three core questions for the detection of obstructive sleep apnea in childhood: An observational study. AB - BACKGROUND: Children with obstructive sleep apnea are at high risk for perioperative airway obstruction. Many "at risk" children may remain unrecognized. The aim of this study is to find a clinically practicable test to identify obstructive sleep apnea in childhood. METHODS: In this pilot study, we prospectively compared four parental questionnaires with the respective findings of subsequent sleep laboratory testing in children. Right before sleep laboratory testing, children's parents answered both the Pediatric Sleep Questionnaire, a subscale of the Sleep Related Breathing Disorder questionnaire (PSQ-SRBD Subscale), and an eight-item questionnaire derived from it. Finally, we condensed the eight-item questionnaire to three core issues: Does your child regularly snore at night? Does your child demonstrate labored breathing during sleep? Does your child have breathing pauses during sleep? With it, two similar questionnaires were generated that differed in the formation of the resulting score. One questionnaire was built by a quotient comparable to the abovementioned questionnaires and a second as quick test that functioned as a simple sum score. Both sensitivity and specificity were determined by using a Receiver Operating Characteristic analysis. RESULTS: In total, 53 children were included in the study. Both the PSQ-SRBD-questionnaire and self-derived eight-item questionnaire failed to reach statistically significant results in detecting obstructive sleep apnea. The set of three core questions with a score built by a quotient was statistically significant and provided sensitivity and a moderate specificity of 0.944 and 0.543, respectively. This could be slightly optimized by creating a simple sum-score (specificity of 0.571). CONCLUSIONS: The use of three core questions may facilitate the detection of pediatric obstructive sleep apnea within the scope of the anesthesia survey. While the study has some limitations, future studies with both unselective collectives and older children might prove this ultra-short questionnaire to be advantageous in detecting pediatric OSA in clinical practices. TRIAL REGISTRATION: German Clinical Trial Register ( DRKS00010408 , https://www.drks.de ); date of registration 26.07.2016. PMID- 29458332 TI - Identification of genetic variants for clinical management of familial colorectal tumors. AB - BACKGROUND: The genetic mechanisms for families who meet the clinical criteria for Lynch syndrome (LS) but do not carry pathogenic variants in the mismatch repair (MMR) genes are still undetermined. We aimed to study the potential contribution of genes other than MMR genes to the biological and clinical characteristics of Norwegian families fulfilling Amsterdam (AMS) criteria or revised Bethesda guidelines. METHODS: The Hereditary Cancer Biobank of the Norwegian Radium Hospital was interrogated to identify individuals with a high risk of developing colorectal cancer (CRC) for whom no pathogenic variants in MMR genes had been found in routine diagnostic DNA sequencing. Forty-four cancer susceptibility genes were selected and analyzed by using our in-house designed TruSeq amplicon-based assay for targeted sequencing. RNA splicing- and protein dedicated in silico analyses were performed for all variants of unknown significance (VUS). Variants predicted as likely to affect splicing were experimentally analyzed by resorting to minigene assays. RESULTS: We identified a patient who met the revised Bethesda guidelines and carried a likely pathogenic variant in CHEK2 (c.470 T > C, p.I157T). In addition, 25 unique VUS were identified in 18 individuals, of which 2 exonic variants (MAP3K1 c.764A > G and NOTCH3 c.5854G >A) were analyzed in the minigene splicing assay and found not to have an effect on RNA splicing. CONCLUSIONS: Among high-risk CRC patients that fulfill the AMS criteria or revised Bethesda guidelines, targeted gene sequencing identified likely pathogenic variant and VUS in other genes than the MMR genes (CHEK2, NOTCH3 and MAP3K1). Our study suggests that the analysis of genes currently excluded from routine molecular diagnostic screens may confer cancer susceptibility. PMID- 29458334 TI - Identification of novel L2HGDH mutation in a large consanguineous Pakistani family- a case report. AB - BACKGROUND: L-2-hydroxyglutaric aciduria (L2HGA) is a progressive neurometabolic disease of brain caused by mutations of in L-2-hydroxyglutarate dehydrogenase (L2HGDH) gene. Cardinal clinical features include cerebellar ataxia, epilepsy, neurodevelopmental delay, intellectual disability, and other clinical neurological deficits. CASE PRESENTATION: We describe an index case of the family presented with generalised tonic-clonic seizure, developmental delay, intellectual disability, and ataxia. Initially, the differential diagnosis was difficult to be established and a SNP genome wide scan identified the candidate region on chromosome 14q22.1. DNA sequencing showed a novel homozygous mutation in the candidate gene L2HGDH (NM_024884.2: c.178G > A; p.Gly60Arg). The mutation p.Gly60Arg lies in the highly conserved FAD/NAD(P)-binding domain of this mitochondrial enzyme, predicted to disturb enzymatic function. CONCLUSIONS: The combination of homozygosity mapping and DNA sequencing identified a novel mutation in Pakistani family with variable clinical features. This is second report of a mutation in L2HGDH gene from Pakistan and the largest family with L2HGA reported to date. PMID- 29458335 TI - Integrated children's clinic care (ICCC) versus a self-directed care pathway for children with a chronic health condition: a multi-centre randomised controlled trial study protocol. AB - BACKGROUND: Children with chronic health conditions have better health-related outcomes when their care is managed in a personalised and coordinated way. However, increased demand on Australian ambulatory care hospital services has led to longer waitlist times to access specialists and appropriate intervention services; placing vulnerable children at increased risk of poorer short-term (e.g. social difficulties) and long-term (e.g. convictions) health and social outcomes. Traditional approaches to increasing frequency and service of delivery are expensive and can have minimal impact on caregiver burden. A community based service-integration approach, rather than self-directed care is proposed as increased service linkages are more likely to occur and improve the health outcomes of children with a chronic health condition. METHODS: An open, unblinded, multi-centre randomised controlled trial in two Australian public hospitals. 112 children (0-16 years) fulfilling the inclusion criteria will be randomised to one of two clinical pathways for management of their chronic health condition: (1) integrated children's care clinic (ICCC) or (2) self-directed care pathway. All children and caregivers will be interviewed at 1 week, and 3, 6 and 12 month time intervals. Primary outcome measures include the Pediatric Quality of Life (PedQOL) questionnaire, Subjective Units of Distress Scale, Child Behaviour Checklist (CBCL) and Rotter's Locus of Control Scale. Secondary outcome measures include the total number of medical appointments, school days missed and quantity of services accessed. Our main objectives are to determine if the ICCC results in better health and economics outcomes compared to the self-directed care pathway. DISCUSSION: The success of a health systems approach needs to be balanced against clinical, mortality and cost-effectiveness data for long-term sustainability within a publicly funded health system. A clinical pathway that is sustainable, cost-effective, provides efficient evidence-based care and improves the quality of life outcomes for children with chronic health conditions has the potential to reduce waitlist times, improve access to health services, increase consumer satisfaction; and prevent costs associated with poorly managed chronic health conditions into adulthood. This study will be the first to provide clinical and health economics data on an integrated care pathway for the management of chronic health conditions in children. On a broader scale, results from this study will help guide care coordination frameworks for children with chronic health conditions; particularly with the introduction and implementation of a National Disability Insurance Scheme (NDIS) across Australia.

PMID- 29458336 TI - Prevalence, aetiologies and prognosis of the symptom dizziness in primary care - a systematic review. AB - BACKGROUND: Dizziness is a common reason for consulting a general practitioner and there is a broad range of possible underlying aetiologies. There are few evidence-based data about prevalence, aetiology and prognosis in primary care. We aimed to conduct a systematic review of symptom-evaluating studies on prevalence, aetiology or prognosis of dizziness in primary care. METHODS: We systematically searched MEDLINE and EMBASE. Two independent researchers screened titles and abstracts according to predefined criteria. We included all studies evaluating the symptoms 'dizziness' or 'vertigo' as a reason for consultation in primary care. We extracted data about study population and methodology and prevalence, aetiology and prognosis. Two raters independently judged study quality and risk of bias. We investigated the variation across studies using forest plots, I2 and prediction intervals. Since we anticipated a great amount of clinical and unexplained statistical heterogeneity, we provided qualitative syntheses instead of pooled estimates. RESULTS: We identified 31 studies (22 on prevalence, 14 on aetiology and 8 on prognosis). Consultation prevalence differs between 1,0 and 15,5%. The most common aetiologies are vestibular/peripheral (5,4-42,1%), benign peripheral positional vertigo (4,3-39,5%), vestibular neuritis (0,6-24,0%), Meniere's disease (1,4-2,7%), cardiovascular disease (3,8-56,8%), neurological disease (1,4-11,4%), psychogenic (1,8-21,6%), no clear diagnosis (0,0-80,2%). While studies based on subjective patient assessment reported improvement rates from 37 to 77%, these findings could not be confirmed when applying instruments that measure symptom severity or quality of life. CONCLUSION: There is a broad variety of possible underlying diseases for the symptom dizziness. There exist only few methodologically sound studies concerning aetiology and prognosis of dizziness. PMID- 29458337 TI - HIV-1 transmission and survival according to feeding options in infants born to HIV-infected women in Yaounde, Cameroon. AB - BACKGROUND: Evidence of 24-months survival in the frame of prevention of mother to-child transmission (PMTCT) cascade-care is scare from routine programs in sub Saharan African (SSA) settings. Specifically, data on infant outcomes according to feeding options remain largely unknown by month-24, thus limiting its breath for public-health recommendations toward eliminating new pediatric HIV-1 infections and improving care. We sought to evaluate HIV-1 vertical transmission and infant survival rates according to feeding options. METHODS: A retrospective cohort-study conducted in Yaounde from April 2008 through December 2013 among 1086 infants born to HIV-infected women and followed-up throughout the PMTCT cascade-care until 24-months. Infants with documented feeding option during their first 3 months of life (408 on Exclusive Breastfeeding [EBF], 663 Exclusive Replacement feeding [ERF], 15 mixed feeding [MF]) and known HIV-status were enrolled. HIV-1 vertical transmission, survival and feeding options were analyzed using Kaplan Meier Survival Estimate, Cox model and Schoenfeld residuals tests, at 5% statistical significance. RESULTS: Overall HIV-1 vertical transmission was 3.59% (39), and varied by feeding options: EBF (2.70%), ERF (3.77%), MF (20%), p = 0.002; without significance between EBF and ERF (p = 0.34). As expected, HIV-1 transmission also varied with PMTCT-interventions: 1.7% (10/566) from ART-group, 1.9% (8/411) from AZT-group, and 19.2% (21/109) from ARV-naive group, p < 0.0001. Overall mortality was 2.58% (28), higher in HIV-infected (10.25%) vs. uninfected (2.29%) infants (p = 0.016); with a survival cumulative probability of 89.3% [79.9%-99.8%] vs. 96.4% [94.8%-97.9% respectively], p = 0.024. Mortality also varied by feeding option: ERF (2.41%), EBF (2.45%), MF (13.33%), p = 0.03; with a survival cumulative probability of 96% [94%-98%] in ERF, 96.4% [94.1%-98.8%] in EBF, and 86.67% [71.06%-100%] in MF, p = 0.04. Using Schoenfeld residuals test, only HIV status was a predictor of survival at 24 months (hazard ratio 0.23 [0.072-0.72], p = 0.01). CONCLUSION: Besides using ART for PMTCT-interventions, practice of MF also drives HIV-1 vertical transmission and mortality among HIV infected children. Thus, throughout PMTCT option B+ cascade-care, continuous counseling on safer feeding options would to further eliminating new MTCT, optimizing response to care, and improving the life expectancy of these children in high-priority countries. PMID- 29458338 TI - Association of matrix metalloprotease 1, 3, and 12 polymorphisms with rheumatic heart disease in a Chinese Han population. AB - BACKGROUND: Rheumatic heart disease (RHD) is an autoimmune disease triggered by acute rheumatic fever (ARF). Matrix metalloproteinases (MMPs) play an important role in the modulation of immune responses. The purpose of this study was to evaluate the association of MMP1, 3, and 12 promoter polymorphisms with RHD in a Han population in Southern China since the 3 genes are localized on the same chromosome and have a combined effect. METHODS: DNA samples were obtained from 90 adult patients with RHD and 90 control subjects. Polymorphisms in MMP1 (rs1799750), MMP3 (rs3025058), and MMP12 (rs2276109) were genotyped by direct sequencing. Differences in genotype and allele frequencies of these polymorphisms were compared between the cases and the controls using Unconditional logistic regression models and Chi-squared test. RESULTS: The 2G/2G genotype of rs1799750 in MMP1 was associated with a significantly higher risk of RHD when compared with the 1G/1G genotype (OR = 3.227; 95% CI:1.118-9.31; p = 0.03). The frequency of allele 2G was higher in patients with RHD compared to the controls (69.4% vs. 58.9%; p = 0.048) No significant differences in genotype and allele frequencies of rs3025058 in MMP3 and rs2276109 in MMP12 were found between the patients with RHD and the controls (p > 0.05). CONCLUSIONS: Our results suggest that rs1799750 in MMP1 might be a risk factor for RHD in a Han population in Southern China, and individuals carrying the 2G/2G genotype are likely more susceptible to RHD. In contrast, rs3025058 in MMP3 and rs2276109 in MMP12 might not contribute to the risk of developing RHD in this population. Further studies with larger samples and other ethnic populations are required to confirm these findings. PMID- 29458339 TI - Association of yield-related traits in founder genotypes and derivatives of common wheat (Triticum aestivum L.). AB - BACKGROUND: Yield improvement is an ever-important objective of wheat breeding. Studying and understanding the phenotypes and genotypes of yield-related traits has potential for genetic improvement of crops. RESULTS: The genotypes of 215 wheat cultivars including 11 founder parents and 106 derivatives were analyzed by the 9 K wheat SNP iSelect assay. A total of 4138 polymorphic single nucleotide polymorphism (SNP) loci were detected on 21 chromosomes, of which 3792 were mapped to single chromosome locations. All genotypes were phenotyped for six yield-related traits including plant height (PH), spike length (SL), spikelet number per spike (SNPS), kernel number per spike (KNPS), kernel weight per spike (KWPS), and thousand kernel weight (TKW) in six irrigated environments. Genome wide association analysis detected 117 significant associations of 76 SNPs on 15 chromosomes with phenotypic explanation rates (R 2 ) ranging from 2.03 to 12.76%. In comparing allelic variation between founder parents and their derivatives (106) and other cultivars (98) using the 76 associated SNPs, we found that the region 116.0-133.2 cM on chromosome 5A in founder parents and derivatives carried alleles positively influencing kernel weight per spike (KWPS), rarely found in other cultivars. CONCLUSION: The identified favorable alleles could mark important chromosome regions in derivatives that were inherited from founder parents. Our results unravel the genetic of yield in founder genotypes, and provide tools for marker-assisted selection for yield improvement.

PMID- 29458340 TI - A microbiome case-control study of recurrent acute otitis media identified potentially protective bacterial genera. AB - BACKGROUND: Recurrent acute otitis media (rAOM, recurrent ear infection) is a common childhood disease caused by bacteria termed otopathogens, for which current treatments have limited effectiveness. Generic probiotic therapies have shown promise, but seem to lack specificity. We hypothesised that healthy children with no history of AOM carry protective commensal bacteria that could be translated into a specific probiotic therapy to break the cycle of re-infection. We characterised the nasopharyngeal microbiome of these children (controls) in comparison to children with rAOM (cases) to identify potentially protective bacteria. As some children with rAOM do not appear to carry any of the known otopathogens, we also hypothesised that characterisation of the middle ear microbiome could identify novel otopathogens, which may also guide the development of more effective therapies. RESULTS: Middle ear fluids, middle ear rinses and ear canal swabs from the cases and nasopharyngeal swabs from both groups underwent 16S rRNA gene sequencing. The nasopharyngeal microbiomes of cases and controls were distinct. We observed a significantly higher abundance of Corynebacterium and Dolosigranulum in the nasopharynx of controls. Alloiococcus, Staphylococcus and Turicella were abundant in the middle ear and ear canal of cases, but were uncommon in the nasopharynx of both groups. Gemella and Neisseria were characteristic of the case nasopharynx, but were not prevalent in the middle ear. CONCLUSIONS: Corynebacterium and Dolosigranulum are characteristic of a healthy nasopharyngeal microbiome. Alloiococcus, Staphylococcus and Turicella are possible novel otopathogens, though their rarity in the nasopharynx and prevalence in the ear canal means that their role as normal aural flora cannot be ruled out. Gemella and Neisseria are unlikely to be novel otopathogens as they do not appear to colonise the middle ear in children with rAOM. PMID- 29458342 TI - Maternal socio-demographic and psychological predictors for risk of developmental delays among young children in Mongolia. AB - BACKGROUND: Factors influencing child development are not well studied in developing settings, and especially in Mongolia. This cohort study examined the relationship between maternal socio-demographic and psychological conditions on risk of young child developmental delay. METHODS: A total of 150 children aged between 13 ~ 24 months old participated in this study. The participants were randomly selected from a pre-existing cohort of 1297 children who were involved in a study on infant bilirubin nomogram development conducted at a tertiary health facility in Mongolia between 2012 and 2013. Child development was evaluated using the Mongolian Rapid Baby Scale (MORBAS), a validated scale for child development. The potential factors for child developmental delay were assessed using a pre-tested questionnaire comprising of 52 questions. Fisher's exact test and multivariable logistic regression analysis were conducted. RESULTS: Seventeen (11%) out of the 150 children that participated in the study were at risk of developmental delay. There was a negative association between the risk of child developmental delay and higher maternal education (AOR 0.15, 95% CI: 0.03-0.66). Increasing maternal age (AOR 1.12, 95%CI: 0.98-1.27), maternal depression symptoms (AOR 4.93, 95%CI: 0.93-26.10), child gender being female (AOR 0.25, 95%CI: 0.06-1.00) and being from single mother household (AOR 0.14, 95%CI: 0.01-1.11) were also predictors for risk of developmental delay - although the association was marginal. CONCLUSIONS: Our findings suggest that being of underprivileged social status, and poor psychological condition of mothers in Mongolia possibly increases the risk of child developmental delays. Interventions targeting these modifiable predictors are needed to develop prevention strategies for child developmental delay. PMID- 29458343 TI - Factors affecting first month adherence due to antiretroviral therapy among HIV positive adults at Felege Hiwot Teaching and Specialized Hospital, north-western Ethiopia; a prospective study. AB - BACKGROUND: Non-adherence to Highly Active Antiretroviral Therapy (HAART) is one of the factors for treatment failure in human immunodeficiency virus (HIV) infected patients in developing countries. The main objective of this study was to identify factors for treatment failure among adult HIV patients based on the assessment of first month adherence in the study area. METHODS: The study was conducted using secondary data from antiretroviral unit at Felege Hiwot Teaching and Specialized Hospital. A prospective study was undertaken on 792 randomly selected adult HIV positive patients who have started HAART. The variable of interest, adherence to HAART was categorized as non-adherence if a patient had taken less than 95% of the prescribed medication and this was measured using pill counts. Descriptive statistics, Chi-square tests of association, independent samples t-test and binary logistic regression were used for data analysis. RESULTS: In first month therapy, 68.2% of the patients belong to adherence group to HAART. As age increases, a patient without cell phone was less likely to be adherent to HAART as compared to patients with cell phone (AOR = 0.661, 95% CI: (0.243, 0.964)). Compared to urban patients, rural patients were less likely to adhere to HAART (AOR = 0.995, 95% CI: (0.403, 0.999)). A patient who did not disclose his/her disease to families or communities had less probability to be adherent to HAART (AOR = 0.325, 95% CI: (0.01, 0.64)). Similarly, a patient who did not get social support (AOR = 0.42, 95% CI: (0,021, 0.473)) had less probability of adherence to HAART. The main reasons for patients to be non adherent were forgetfulness, side effects, feeling sick and running out of medication. CONCLUSION: This study indentified certain groups of patients who are at higher risk and who need counseling. Such groups should be targeted and tailored for improvement of adherence to HAART among HIV positive adults. The health care providers should advise the community to provide social support to HIV positive patients whenever their disease is disclosed. On the other hand, patients should disclose their disease to community to get integrated supports. HIV infected patients who are directed to start HAART should adhere the prescribed medication. For the adherence to be effective, patients who have cell phone should use them as reminder to take pills on time. PMID- 29458344 TI - The DEsire to DIe in Palliative care: Optimization of Management (DEDIPOM) - a study protocol. AB - BACKGROUND: A desire to die (DD) is frequent in palliative care (PC). However, uncertainty remains as to the appropriate therapeutic response. (Proactive) discussion of DD is not usually part of standard care. To support health practitioners' (HPs) reactions to a patient's DD, a training program has been developed, piloted and evaluated. Within this framework, a first draft of a semi structured clinical interview schedule with prompts (CISP) has been developed, including recommendations for action to support HPs' self-confidence. The aim of this study is the further development of the CISP to support routine exploration of death and dying distress and proactive addressing of a DD. METHODS: This observatory, prospective health services study comprises a three step study design: 1. Revision of the CISP and consensus finding based on semi-structured interviews with patients and a Delphi process with (inter-)national experts, patient representatives and relatives; 2. Increasing confidence in HPs through a 2 day-training program using the consented CISP; 3. A formative quantitative evaluation of conversations between HPs and patients (300 palliative patients at three time points) and a qualitative evaluation based on interview triads of patients, relatives and HPs. The evaluation of conversations will include patient oriented outcomes, including perceived relationships with HPs and death and dying distress. We will also consider aspects of social inequality and gender. DISCUSSION: The intervention can provide a framework for open discussion of DD and a basis for enhancing a trustful HP-patient relationship in which such difficult topics can be addressed. The benefits of this study will include (a) the creation of the first consented semi-structured approach to identify and address DD and to respond therapeutically, (b) the multi-professional enhancement of confidence in dealing with patients' DD and an intervention that can flexibly be integrated into other training and education programs and (c) an evaluation of effects of this intervention on patients, relatives and HPs, with attention to social inequality and gender. TRIAL REGISTRATION: The study is registered in the German Clinical Trials Register ( DRKS00012988 ; registration date: 27.9.2017) and in the Health Services Research Database ( VfD_DEDIPOM_17_003889 ; registration date: 14.9.2017). PMID- 29458345 TI - Genetic polymorphisms in bone morphogenetic protein receptor type IA gene predisposes individuals to ossification of the posterior longitudinal ligament of the cervical spine via the smad signaling pathway. AB - BACKGROUND: The present study investigated the molecular mechanisms underlying the 4A > C and -349C > T single nucleotide polymorphisms (SNPs) in bone morphogenetic protein receptor type IA (BMPR-IA) gene, which significantly associated with the occurrence and the extent of ossification of the posterior longitudinal ligament (OPLL) in the cervical spine. METHODS: The SNPs in BMPR-IA gene were genotyped, and the association with the occurrence and severity of OPLL were evaluated in 356 OPLL patients and 617 non-OPLL controls. In stably transfected mouse embryonic mesenchymal stem cells (C3H10T1/2), the expression levels of the BMPR-IA gene and Smad4 protein as well as phosphorylated Smad1/5/8 were detected by Western blotting. In addition, the alkaline phosphatase (ALP) and osteocalcin (OC) activity of osteogenesis specificity protein was assessed using the ALP quantitation and osteocalcin radioimmunoassay kit, respectively. RESULTS: The 4A > C and the -349C > T polymorphisms of BMPR-IA gene were significantly associated with the development of OPLL in the cervical spine. The C allele type in 4A > C polymorphism significantly increases the occurrence and the extent of OPLL. The T allele type in -349C > T polymorphism significantly increases the susceptibility to OPLL, but not the extent of OPLL. The current results further validate our previous observations. The expression levels of BMPR IA gene were significantly increased in pcDNA3.1/BMPR-IA (mutation type, MT -349C > T; MT 4A > C; MT -349C > T and 4A > C) vector-transfected C3H10T1/2 cells compared to the wild type (WT) vector-transfected cells. The levels of phosphorylated Smad1/5/8 and ALP activity were significantly increased in pcDNA3.1/BMPR-IA (MT -349C > T) vector-transfected C3H10T1/2 cells compared to the WT vector-transfected cells. However, no significant differences were observed in the protein levels of phosphorylated Smad1/5/8 and the ALP activity between MT A/C and WT vector-transfected cells. In addition, no significant differences were observed in the Smad4 protein levels among the experimental groups, as well as in the OC activity between WT vector-transfected and MT C/T, MT A/C, MT C/T and MT A/C vector-transfected cells. CONCLUSIONS: Our results suggest that Smad signaling pathway may play important roles in the pathological process of OPLL induced by SNPs in BMPR-IA gene. These results will help to clarify the molecular mechanisms underlying the SNP and gene susceptibility to OPLL. PMID- 29458346 TI - Associations between ERalpha/beta gene polymorphisms and osteoporosis susceptibility and bone mineral density in postmenopausal women: a systematic review and meta-analysis. AB - BACKGROUND: Many studies have reported associations between estrogen receptor (ER) gene polymorphisms and postmenopausal osteoporosis (PMOP) risk and bone mineral density (BMD), but the results are controversial. The aim of the present meta-analysis is to verify the association between ERalpha and ERbeta gene polymorphisms and osteoporosis susceptibility and BMD in postmenopausal women. METHODS: PubMed, EMBASE, Web of Science, the Cochrane Library and China WeiPu Library were searched. OR and WMD with 95% CI were calculated to assess the association. RESULTS: Overall, no significant association was observed between ERalpha XbaI, ERalpha PvuII and PMOP susceptibility in either overall, Caucasian or Asian populations. ERalpha G2014A was significantly associated with a decreased risk of PMOP in Caucasian populations. There was a significant association between ERbeta RsaI and PMOP risk in both overall and Asian populations. Caucasian PMOP women with ERalpha XbaI XX and Xx genotypes had a higher LS Z value than women with xx genotype. ERalpha XbaI XX genotype was associated with increased FN BMD in overall and Caucasian populations, an increased FN Z value in Asians, and a decreased FN Z value in Caucasians. There was also a significant association between ERalpha XbaI Xx genotype and an increased FN Z value in either Asians or Caucasians. ERalpha PvuII PP genotype was associated with a low LS Z value in Caucasians and a low FN BMD and Z value in Asians. Pp genotype in PMOP women was significantly correlated with low LS BMD in overall populations, a low FN Z value in either overall, Caucasian or Asian populations. CONCLUSION: Each ERalpha and ERbeta gene polymorphism might have different impact on PMOP risk and BMD in various ethnicities. PMID- 29458347 TI - The contribution of a MOOC to community discussions around death and dying. AB - BACKGROUND: Advances in medicine have helped many to live longer lives and to be able to meet health challenges. However death rates are anticipated to increase given the ageing population and chronic disease progression. Being able to talk about death is seen to be important in normalising death as part of life and supporting preparedness for death. Massive Open Online Courses (MOOCs) provide opportunities for the community to engage in collaborative learning. A 5 week MOOC was developed covering four main topics (language and humour, representations of death, medicalisation of dying, and digital dying) aiming: To enable participants to openly and supportively discuss and learn about issues around living, death and dying, To explore the normally unheard opinions and views of Australians around death and dying, and To determine what effect online learning and discussions offered through the MOOC had on participants' feelings and attitudes towards death and dying. METHODS: Data was captured on engagement rates in the various MOOC activities. Death Attitudes were measured by five items representing the MOOC's learning objectives and completed at enrolment and conclusion. MOOC Satisfaction was measured with six items at the end of the MOOC. Descriptive statistics were produced for each variable and Chi-Square Tests of Independence assessed the extent of the relationship between categorical variables. Socio-demographic variables were examined as predictors of the outcome variables of MOOC engagement, MOOC satisfaction, and death attitudes. Ethical approval was received from Flinders University Social and Behavioural Research Ethics Committee (Project No. 7247). RESULTS: One thousand one hundred fifty six people enrolled in the Dying2Learn MOOC with 895 participating in some way. Enrolees were primarily female (92.1%). Age ranged from 16 to 84 (mean = 49.5, SD = 12.3). MOOC satisfaction scores were high. Responses to the experience of participating in the MOOC were very positive, with mean scores ranging from 4.3 to 4.6 (aligning with agreement and strong agreement to statements on the value of participating). Death Attitudes were positive at commencement but increased significantly following participation. CONCLUSIONS: The Dying2Learn MOOC provided an environment that enabled open and supportive discussion around death and dying and influenced attitudinal change. PMID- 29458348 TI - Patients' and caregivers' experiences of using continuous glucose monitoring to support diabetes self-management: qualitative study. AB - BACKGROUND: Continuous glucose monitoring (CGM) enables users to view real-time interstitial glucose readings and provides information on the direction and rate of change of blood glucose levels. Users can also access historical data to inform treatment decisions. While the clinical and psychological benefits of CGM are well established, little is known about how individuals use CGM to inform diabetes self-management. We explored participants' experiences of using CGM in order to provide recommendations for supporting individuals to make optimal use of this technology. METHODS: In-depth interviews (n = 24) with adults, adolescents and parents who had used CGM for >=4 weeks; data were analysed thematically. RESULTS: Participants found CGM an empowering tool because they could access blood glucose data effortlessly, and trend arrows enabled them to see whether blood glucose was rising or dropping and at what speed. This predicative information aided short-term lifestyle planning and enabled individuals to take action to prevent hypoglycaemia and hyperglycaemia. Having easy access to blood glucose data on a continuous basis also allowed participants to develop a better understanding of how insulin, activity and food impacted on blood glucose. This understanding was described as motivating individuals to make dietary changes and break cycles of over-treating hypoglycaemia and hyperglycaemia. Participants also described how historical CGM data provided a more nuanced picture of blood glucose control than was possible with blood glucose self-monitoring and, hence, better information to inform changes to background insulin doses and mealtime ratios. However, while participants expressed confidence making immediate adjustments to insulin and lifestyle to address impending hypoglycaemia and hypoglycaemia, most described needing and expecting health professionals to interpret historical CGM data and determine changes to background insulin doses and mealtime ratios. While alarms could reinforce a sense of hypoglycaemic safety, some individuals expressed ambivalent views, especially those who perceived alarms as signalling personal failure to achieve optimal glycaemic control. CONCLUSIONS: CGM can be an empowering and motivational tool which enables participants to fine-tune and optimize their blood glucose control. However, individuals may benefit from psycho-social education, training and/or technological support to make optimal use of CGM data and use alarms appropriately. PMID- 29458349 TI - Role of health determinants in a measles outbreak in Ecuador: a case-control study with aggregated data. AB - BACKGROUND: In 2011-2012, an outbreak of measles occurred in Ecuador. This study sought to ascertain which population characteristics were associated. METHODS: Case-control study of aggregate data. The unit of analysis was the parish (smallest geographic division). The national communicable disease surveillance database was used to identify 52 case parishes (with at least one confirmed case of measles) and 972 control parishes (no cases of measles). A hierarchical model was used to determine the association of measles with population characteristics and access to health care. RESULTS: Case parishes were mostly urban and had a higher proportion of children under 1 year of age, heads of household with higher educational attainment, larger indigenous population, lower rates of measles immunization, and lower rates of antenatal care visit attendance. On multivariate analysis, associations were found with educational attainment of head of household >=8 years (OR: 0.29; 95%CI 0.15-0.57) and >=1.4% indigenous population (OR: 3.29; 95%CI 1.63-6.68). Antenatal care visit attendance had a protective effect against measles (OR: 0.98; 95%CI 0.97-0.99). Measles vaccination was protective of the outbreak (OR: 0.97; 95%CI 0.95-0.98). The magnitude of these associations was modest, but represents the effect of single protective factors, capable of acting at the population level regardless of socioeconomic, biological, and environmental confounding factors. CONCLUSION: In Ecuador, the parishes with the highest percentage of indigenous populations and those with the lowest vaccination coverage were the most vulnerable during the measles outbreak. PMID- 29458350 TI - Obesity and risk of respiratory tract infections: results of an infection-diary based cohort study. AB - BACKGROUND: Respiratory tract infections (RTIs) are a major morbidity factor contributing largely to health care costs and individual quality of life. The aim of the study was to test whether obesity (BMI >= 30 kg/m2) is one of the risk factors underlying frequent RTIs in the German adult population. METHODS: We recruited 1455 individuals between 18 to 70 years from a cross-sectional survey on airway infections in Germany and invited them to self-report in diaries incident RTIs experienced during three consecutive winter/spring seasons. RTIs reported in these 18 months and summary measures adding-up individual RTIs were the outcomes of interest. RESULTS: Compared to individuals with normal weight, obese individuals reported a consistently higher frequency of upper and lower RTIs and predominantly fell in the upper 10% group of a diary sumscore adding-up 10 different RTI symptoms over time. Obesity was associated both with lower RTIs (adjustedOR = 2.02, 95%CI = 1.36-3.00) and upper RTIs (adjustedOR = 1.55, 95%CI = 1.22-1.96). Adjusting for demographic and lifestyle variables did only marginally affect ORs. Stratified analyses suggested a stronger association for women and effect modifications by sports activity and dietary habits. CONCLUSIONS: We confirm the association of obesity with infection burden and present evidence for putative interaction with sports activity and dietary patterns. PMID- 29458351 TI - CEMiTool: a Bioconductor package for performing comprehensive modular co expression analyses. AB - BACKGROUND: The analysis of modular gene co-expression networks is a well established method commonly used for discovering the systems-level functionality of genes. In addition, these studies provide a basis for the discovery of clinically relevant molecular pathways underlying different diseases and conditions. RESULTS: In this paper, we present a fast and easy-to-use Bioconductor package named CEMiTool that unifies the discovery and the analysis of co-expression modules. Using the same real datasets, we demonstrate that CEMiTool outperforms existing tools, and provides unique results in a user friendly html report with high quality graphs. Among its features, our tool evaluates whether modules contain genes that are over-represented by specific pathways or that are altered in a specific sample group, as well as it integrates transcriptomic data with interactome information, identifying the potential hubs on each network. We successfully applied CEMiTool to over 1000 transcriptome datasets, and to a new RNA-seq dataset of patients infected with Leishmania, revealing novel insights of the disease's physiopathology. CONCLUSION: The CEMiTool R package provides users with an easy-to-use method to automatically implement gene co-expression network analyses, obtain key information about the discovered gene modules using additional downstream analyses and retrieve publication-ready results via a high-quality interactive report. PMID- 29458353 TI - Isolated unilateral temporalis muscle hypertrophy in a child: a case report with literature review. AB - BACKGROUND: Temporalis muscle hypertrophy is a rare entity of masticatory muscle hypertrophy. All types of masticatory muscle hypertrophies have been documented of which temporalis muscle hypertrophy is one. Temporalis muscle hypertrophy is most commonly bilateral and usually associated with other types of masticatory muscles hypertrophy such as masseter or pterygoid hypertrophy. However, isolated unilateral temporalis muscle hypertrophy is extremely rare and only 9 cases have been reported to date in English literature since 1990 with only two patients less than 18 years. There is no exact etiology identified and the diagnosis is made by muscle biopsy combined with imaging study to exclude other possibilities. Age at presentation is ranges from 15 to 65 years with involvement of both sexes. We report the youngest child who is a seven year old girl with right side isolated unilateral temporalis muscle hypertrophy. CASE PRESENTATION: In this patient, we discuss the youngest child with isolated unilateral temporalis muscle hypertrophy and literature review to date. The patient is a seven year old female presenting with painless swelling of the right temporalis muscle. There had no features of inflammation, trauma, neoplasm or history of parafunctions such as bruxism. The child was not complaining significantly headache or visual disturbances as well. She had undergone radiological assessment with ultrasound scan and contrast MRI. The diagnosis was confirmed by muscle biopsy which shows normal muscle architecture. She was managed conservatively with regular follow up. CONCLUSION: Isolated unilateral temporalis muscle hypertrophy is extremely rare in children. However this case raises the importance of considering alternative diagnoses despite the condition being rare in the pediatric population. PMID- 29458352 TI - Reducing GHG emissions while improving diet quality: exploring the potential of reduced meat, cheese and alcoholic and soft drinks consumption at specific moments during the day. AB - BACKGROUND: The typical Western diet is associated with high levels of greenhouse gas (GHG) emissions and with obesity and other diet-related diseases. This study aims to determine the impact of adjustments to the current diet at specific moments of food consumption, to lower GHG emissions and improve diet quality. METHODS: Food consumption in the Netherlands was assessed by two non-consecutive 24-h recalls for adults aged 19-69 years (n = 2102). GHG emission of food consumption was evaluated with the use of life cycle assessments. The population was stratified by gender and according to tertiles of dietary GHG emission. Scenarios were developed to lower GHG emissions of people in the highest tertile of dietary GHG emission; 1) reducing red and processed meat consumed during dinner by 50% and 75%, 2) replacing 50% and 100% of alcoholic and soft drinks (including fruit and vegetable juice and mineral water) by tap water, 3) replacing cheese consumed in between meals by plant-based alternatives and 4) two combinations of these scenarios. Effects on GHG emission as well as nutrient content of the diet were assessed. RESULTS: The mean habitual daily dietary GHG emission in the highest tertile of dietary GHG emission was 6.7 kg CO2 equivalents for men and 5.1 kg CO2-equivalents for women. The scenarios with reduced meat consumption and/or replacement of all alcoholic and soft drinks were most successful in reducing dietary GHG emissions (ranging from - 15% to - 34%) and also reduced saturated fatty acid intake and/or sugar intake. Both types of scenarios lead to reduced energy and iron intakes. Protein intake remained adequate. CONCLUSIONS: Reducing the consumption of red and processed meat during dinner and of soft and alcoholic drinks throughout the day leads to significantly lower dietary GHG emissions of people in the Netherlands in the highest tertile of dietary GHG emissions, while also having health benefits. For subgroups of the population not meeting energy or iron requirements as a result of these dietary changes, low GHG emission and nutritious replacement foods might be needed in order to meet energy and iron requirements. PMID- 29458355 TI - Healthy Parent Carers programme: development and feasibility of a novel group based health-promotion intervention. AB - BACKGROUND: Parent carers of disabled children report poor physical health and mental wellbeing. They experience high levels of stress and barriers to engagement in health-related behaviours and with 'standard' preventive programmes (e.g. weight loss programmes). Interventions promoting strategies to improve health and wellbeing of parent carers are needed, tailored to their specific needs and circumstances. METHODS: We developed a group-based health promotion intervention for parent carers by following six steps of the established Intervention Mapping approach. Parent carers co-created the intervention programme and were involved in all stages of the development and testing. We conducted a study of the intervention with a group of parent carers to examine the feasibility and acceptability. Standardised questionnaires were used to assess health and wellbeing pre and post-intervention and at 2 month follow up. Participants provided feedback after each session and took part in a focus group after the end of the programme. RESULTS: The group-based Healthy Parent Carers programme was developed to improve health and wellbeing through engagement with eight achievable behaviours (CLANGERS - Connect, Learn, be Active, take Notice, Give, Eat well, Relax, Sleep), and by promoting empowerment and resilience. The manualised intervention was delivered by two peer facilitators to a group of seven parent carers. Feedback from participants and facilitators was strongly positive. The study was not powered or designed to test effectiveness but changes in measures of participants' wellbeing and depression were in a positive direction both at the end of the intervention and 2 months later which suggest that there may be a potential to achieve benefit. CONCLUSIONS: The Healthy Parent Carers programme appears feasible and acceptable. It was valued by, and was perceived to have benefited participants. The results will underpin future refinement of the intervention and plans for evaluation. PMID- 29458354 TI - The slowdown of Y chromosome expansion in dioecious Silene latifolia due to DNA loss and male-specific silencing of retrotransposons. AB - BACKGROUND: The rise and fall of the Y chromosome was demonstrated in animals but plants often possess the large evolutionarily young Y chromosome that is thought has expanded recently. Break-even points dividing expansion and shrinkage phase of plant Y chromosome evolution are still to be determined. To assess the size dynamics of the Y chromosome, we studied intraspecific genome size variation and genome composition of male and female individuals in a dioecious plant Silene latifolia, a well-established model for sex-chromosomes evolution. RESULTS: Our genome size data are the first to demonstrate that regardless of intraspecific genome size variation, Y chromosome has retained its size in S. latifolia. Bioinformatics study of genome composition showed that constancy of Y chromosome size was caused by Y chromosome DNA loss and the female-specific proliferation of recently active dominant retrotransposons. We show that several families of retrotransposons have contributed to genome size variation but not to Y chromosome size change. CONCLUSIONS: Our results suggest that the large Y chromosome of S. latifolia has slowed down or stopped its expansion. Female specific proliferation of retrotransposons, enlarging the genome with exception of the Y chromosome, was probably caused by silencing of highly active retrotransposons in males and represents an adaptive mechanism to suppress degenerative processes in the haploid stage. Sex specific silencing of transposons might be widespread in plants but hidden in traditional hermaphroditic model plants. PMID- 29458357 TI - Genomic screening for monogenic forms of diabetes. AB - Adult-onset, or type II diabetes mellitus (T2DM) has a complex genetic architecture, from hundreds of genes with low penetrance, common susceptibility variants (e.g., TCF7L2), to a set of more than ten genes that, when mutated, can cause a single-gene or Mendelian form of T2DM (e.g., GCK). It is a clinical challenge to identify patients with the uncommon (2-3%) form of T2DM, typically classified as maturity-onset diabetes of the young (MODY). Bansal et al. (BMC Med 15:213, 2017) used a gene panel test approach to test patients with diabetes for single-gene causes of MODY. They found that nearly 2% of younger patients had pathogenic variants in one of seven genes. These data confirm prior studies showing that Mendelian or single-gene MODY can masquerade as garden variety T2DM. The implications of these results for wider general medicine and the future implementation of clinical genome sequencing are discussed.Please see related article: https://bmcmedicine.biomedcentral.com/articles/10.1186/s12916-017-0977 3. PMID- 29458356 TI - Prevalence of attention-deficit/hyperactivity disorder symptoms and their associations with sleep schedules and sleep-related problems among preschoolers in mainland China. AB - BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) among children is an increasing public health concern. The identification of behavioral risk factors, including sleep quality, has important public health implications for prioritizing behavioral intervention strategies for ADHD. Herein, this study aimed to investigate the prevalence of high levels of ADHD symptoms and to explore the association between sleep schedules, sleep-related problems and ADHD symptoms among preschoolers aged 3 to 6 years in mainland China. METHODS: A cross sectional study was conducted, comprising a large sample of 15,291 preschoolers in Ma'anshan city of Anhui Province in China. ADHD symptoms were assessed by the 10-item Chinese version of the Conners Abbreviated Symptom Questionnaire (C-ASQ). Sleep-related variables included caregivers' responses to specific questions addressing children's daytime and nighttime sleep schedules, as well as sleep related behaviors. Data on other factors were also collected, such as socio demographic characteristics, TV viewing duration on weekdays and weekends, and outdoor activities. Logistic regression models were used to analyze the relationships between sleep schedules, sleep-related problems and ADHD symptoms. RESULTS: Approximately 8.6% of the total sample of preschoolers had high levels of ADHD symptoms, with boys having higher levels than girls (9.9% vs. 7.2%). In the logistic regression analysis, after adjusting for TV viewing duration, outdoor activities, and socio-demographic characteristics, delayed bedtime was significantly associated with a risk of high levels of ADHD symptoms, with odds ratios (OR) of 2.50 [95% confidence interval (CI): 2.09 ~ 3.00] and 2.04 (95% CI: 1.72 ~ 2.42) for weekdays and weekends, respectively. Longer time falling asleep (>= 31 min) (OR = 1.76, 95% CI: 1.47 ~ 2.11), no naps (OR = 1.57, 95% CI: 1.34 ~ 1.84) and frequent sleep-related problems (OR = 4.57, 95% CI: 3.86 ~ 5.41) were also significantly associated with an increased risk of high levels of ADHD symptoms, while longer sleep duration (> 8.5 h) was associated with a decreased risk of high levels of ADHD symptoms (OR = 0.76, 95% CI: 0.67~ 0.87). CONCLUSIONS: ADHD symptoms are prevalent in preschoolers in Ma'anshan region, China. Undesirable sleep schedules and sleep-related problems among preschoolers confer a risk of ADHD symptoms, highlighting the finding that beneficial and regular sleep habits potentially attenuate ADHD symptoms among preschoolers. PMID- 29458358 TI - Effective behavioral intervention strategies using mobile health applications for chronic disease management: a systematic review. AB - BACKGROUND: Mobile health (mHealth) has continuously been used as a method in behavioral research to improve self-management in patients with chronic diseases. However, the evidence of its effectiveness in chronic disease management in the adult population is still lacking. We conducted a systematic review to examine the effectiveness of mHealth interventions on process measures as well as health outcomes in randomized controlled trials (RCTs) to improve chronic disease management. METHODS: Relevant randomized controlled studies that were published between January 2005 and March 2016 were searched in six databases: PubMed, CINAHL, EMBASE, the Cochrane Library, PsycINFO, and Web of Science. The inclusion criteria were RCTs that conducted an intervention using mobile devices such as smartphones or tablets for adult patients with chronic diseases to examine disease management or health promotion. RESULTS: Of the 12 RCTs reviewed, 10 of the mHealth interventions demonstrated statistically significant improvement in some health outcomes. The most common features of mHealth systems used in the reviewed RCTs were real-time or regular basis symptom assessments, pre-programed reminders, or feedbacks tailored specifically to the data provided by participants via mHealth devices. Most studies developed their own mHealth systems including mobile apps. Training of mHealth systems was provided to participants in person or through paper-based instructions. None of the studies reported the relationship between health outcomes and patient engagement levels on the mHealth system. CONCLUSIONS: Findings from mHealth intervention studies for chronic disease management have shown promising aspects, particularly in improving self-management and some health outcomes. PMID- 29458359 TI - In-utero exposure to phenols and phthalates and the intelligence quotient of boys at 5 years. AB - BACKGROUND: There are concerns that developmental exposure to endocrine disrupting chemicals such as phenolic compounds and phthalates could affect child cognitive function. Epidemiological studies tackling this question have mainly focused on phthalate metabolites and bisphenol A, but not on the other phenolic compounds. Our study aimed to assess the relationship between in-utero exposure to phthalates, bisphenol A and other phenolic compounds (parabens, triclosan, dichlorophenols and benzophenone-3) and the Intelligence Quotient (IQ) of boys at 5-6 years. METHODS: In 452 mother-son dyads from the French EDEN cohort, we measured 11 phthalate metabolites and 9 phenolic compounds (4 parabens, benzophenone-3, bisphenol A, 2 dichlorophenols and triclosan) in spot urine samples collected between 22 and 29 gestational weeks. Verbal and performance IQ of children were assessed at 5-6 years by a psychologist using the Wechsler Preschool and Primary Scale of Intelligence (WPPSI). We used adjusted Structural Equation Models (SEM) combined with Benjamini and Hochberg false discovery rate correction to assess the associations between maternal urine phenol and phthalate metabolite concentrations considered simultaneously and the boys' IQ. RESULTS: No phenol or phthalate metabolite concentration was negatively associated with the boys' verbal or performance IQ (uncorrected p-values >=0.09). Mono(3 carboxypropyl) phthalate tended to be associated with increased verbal IQ (beta = 0.136, 95% confidence interval, 0.01; 0.27). This association disappeared after correction for multiple comparison (corrected p-value, 0.71). CONCLUSION: Our results did not provide evidence of an inverse association between in-utero exposure to phenols or phthalates and verbal and performance IQ among boys. Since phenols and phthalates may have sex-specific effects, these null findings cannot be generalized to girls. Limitations included use of a single spot urine sample to assess exposures and lack of consideration of postnatal exposures. PMID- 29458360 TI - Care-'less': exploring the interface between child care and parental control in the context of child rights for workers in children's homes in Ghana. AB - BACKGROUND: This study explored how employed caregivers experience the interface between child care, parental control and child rights in the context of Children's Homes in Ghana. The focus was on investigating caregiver perceptions of proper child care, their experiences with having to work with child rights principles and the implication of these for their relationships with the children and the care services they deliver. METHODS: Adopting a qualitative approach with phenomenological design, data were collected from 41 caregivers in two children's homes in Ghana using focus group discussions and in-depth interviews. RESULTS: It emerged that caregivers experienced frustrations with perceived limitations that child rights principles place on their control over the children describing it as lessening and, at the same time, complicating the care services they provide. CONCLUSIONS: The findings suggest a need for a review of the implementation strategies of the child rights approach in that context. A re-organization of the children's homes environment and re-orientation of caregivers and children regarding their relationship is also suggested. PMID- 29458361 TI - Health services in Trinidad: throughput, throughput challenges, and the impact of a throughput intervention on overcrowding in a public health institution. AB - BACKGROUND: Throughput might be partially responsible for sub-optimum organisational and medical outcomes. The present study examined throughput and the challenges to ensuring optimum throughput in hospitals, and determined the effectiveness of a throughput intervention in reducing overcrowding in a public healthcare institution in Trinidad and Tobago. METHODS: First, a literature review of throughput and its processes in relation to improving hospital care was conducted. Second, the challenges to throughput in healthcare were reviewed. Data were also collected from print media, hospital records, and the central statistical office in Trinidad and Tobago to discuss throughput and describe the throughput status in hospitals. Finally, the effect of a throughput intervention on overcrowding was determined. The intervention was implemented over six months, from October 2010 to March 2011, and comprised three stages of a five-stage throughput process: transferring patients to a specific medical ward, bedside electrocardiograms (ECG), and promptly obtaining patient investigative reports and patient files. RESULTS: Problems with the throughput process led to prolonged delays or failures in obtaining lab reports, radiology services, ECGs, and pharmaceutical supplies, as well as inadequate social work services and other specialised services. During the throughput intervention, there was a reduction in overcrowding/overflow to 5-10 patients per day with a daily admission rate of 58. However, at post-intervention, there was increased overcrowding/overflow to 20-30 per day but fewer admissions (52 per day) i.e. similar to pre-intervention period. Additionally, there was an increase in bed complement in the department of medicine from 209 (2011) to 227 (2012). Overcrowding continued into 2016 and beyond: medical admissions in 2016 were 46.4 per day and the medical bed capacity was 327 (indicating a 44% increase in capacity from 2012). CONCLUSION: Hospital throughput processes are currently suboptimum. Improving specific throughput processes or targeting the greatest primary constraints might help decrease overcrowding.

PMID- 29458363 TI - Rollout of rapid point of care tests for antenatal syphilis screening in Ghana: healthcare provider perspectives and experiences. AB - BACKGROUND: Effective implementation of rapid point of care tests (POCTs) for antenatal syphilis screening especially in settings where antenatal care attendance is high, can significantly increase screening coverage and treatment uptake. The operational challenges of introducing rapid syphilis POCTs at scale needs to be investigated. This study explores healthcare providers' experiences and challenges in antenatal syphilis screening following the national rollout of rapid syphilis POCTs in Ghana. METHODS: Prior to the main study, we undertook a desk review of key syphilis policy documents, and conducted key stakeholder interviews and a baseline survey of syphilis screening practices. Antenatal syphilis screening had been poorly implemented mainly due to inadequate technical and logistic support, and lack of monitoring and supervision. For the main research, semi-structured interviews were conducted with 51 purposively selected healthcare staff involved in antenatal syphilis screening in 15 health facilities in three regions, representative of all levels of healthcare in Ghana and two regional programme coordinators, at least four months after the rollout. The interviews were supplemented with an audit of the conduct of antenatal care, syphilis-related supplies and other maternal and newborn interventions. Qualitative data were coded and analysed using Nvivo software. RESULTS: Syphilis screening with rapid POCTs was integrated into antenatal care in almost all (13/15) the facilities surveyed. Testing and treatment were offered free of charge to pregnant women, their partners and babies. In most facilities, midwives were performing syphilis tests together with HIV tests. Operational challenges included: inadequate training and lack of refresher training, lack of clear testing guidelines, clear channels of communication, supervision, and guidance on treatment and referral procedures, frequent stockouts of, or expired test kits, staff overload, and poor documentation of test results and treatment. CONCLUSION: Although syphilis screening with rapid syphilis POCTs was integrated into antenatal care, key challenges, particularly around supply chain and supervision, need to be addressed to improve and sustain such a programme. PMID- 29458364 TI - Transgenerational effects of polychlorinated biphenyls: 1. Development and physiology across 3 generations of rats. AB - BACKGROUND: Polychlorinated biphenyls (PCBs) are persistent organic environmental contaminants and known endocrine-disrupting chemicals (EDCs). Previous studies demonstrated that developmental exposure to the weakly estrogenic PCB mixture Aroclor 1221 (A1221) in Sprague-Dawley rats altered sexual development, adult reproductive physiology and body weight. The current study tested the hypothesis that prenatal A1221 exposure not only disrupts these endpoints within an exposed individual's (F1 generation) lifespan, but may also affect subsequent generations (F2-F3). METHODS: We treated pregnant female rats on embryonic days (E) 16 and E18 with A1221 (1 mg/kg), estradiol benzoate (50 MUg/kg, positive estrogenic control), or vehicle (3% DMSO in sesame oil, negative control). Endpoints related to sexually dimorphic developmental trajectories of reproductive and developmental physiology were measured, and as adults, reproductive endocrine status was assessed, in the F1, F2, and F3 generations. RESULTS: Significant effects of transgenerational EDCs were found for body weight and serum hormones. The A1221 descendants had significantly higher body weight in the F2-maternal lineage throughout postnatal development, and in F3-maternal lineage animals after weaning. In females, generation- and lineage-specific effects of exposure were found for serum progesterone and estradiol. Specifically, serum progesterone concentrations were lower in F2-A1221 females, and higher in F3-A1221 females, compared to their respective F2- and F3-vehicle counterparts. Serum estradiol concentrations were higher in F3-A1221 than F3-vehicle females. Reproductive and adrenal organ weights, birth outcomes, sex ratio, and estrous cycles, were unaffected. It is notable that effects of A1221 were only sometimes mirrored by the estrogenic control, EB, indicating that the mechanism of action of A1221 was likely via non-estrogenic pathways. CONCLUSIONS: PCBs caused body weight and hormonal effects in rats that were not observed in the directly exposed F1 offspring, but emerged in F2 and F3 generations. Furthermore, most effects were in the maternal lineage; this may relate to the timing of exposure of the F1 fetuses at E16 and 18, when germline (the future F2 generation) epigenetic changes diverge in the sexes. These results showing transgenerational effects of EDCs have implications for humans, as we are now in the 3rd generation since the Chemical Revolution of the mid-twentieth century, and even banned chemicals such as PCBs have a persistent imprint on the health of our descendants. PMID- 29458366 TI - Inequity in dialysis related practices and outcomes in Aotearoa/New Zealand: a Kaupapa Maori analysis. AB - BACKGROUND: In Aotearoa/New Zealand, Maori, as the indigenous people, experience chronic kidney disease at three times the rate of non-Maori, non-Pacific New Zealanders. Maori commence dialysis treatment for end-stage kidney disease at three times the rate of New Zealand European adults. To examine for evidence of inequity in dialysis-related incidence, treatment practices, and survival according to indigeneity in Aotearoa/New Zealand, utilising a Kaupapa Maori approach. METHODS: We conducted a retrospective cohort study involving adults who commenced treatment for end-stage kidney disease in Aotearoa/New Zealand between 2002 and 2011. We extracted data from the Australian and New Zealand Dialysis and Transplant Registry (ANZDATA) linked to the New Zealand National Health Index (NHI). Propensity score methods were used to assemble a cohort of 1039 Maori patients matched 1:1 on clinical and socio-demographic characteristics with a cohort of 1026 non-Maori patients. We compared incidence of end-stage kidney disease and treatment practices. Differences in the risks of all-cause mortality during treatment between propensity-matched cohorts were estimated using Cox proportional hazards and generalised linear models. RESULTS: Non-Maori patients were older, more frequently lived in urban areas (83% versus 67% [standardised difference 0.38]) and bore less socioeconomic deprivation (36% living in highest decile areas versus 14% [0.53]). Fewer non-Maori patients had diabetes (35% versus 69%, [- 0.72]) as a cause of kidney failure. Non-Maori patients were more frequently treated with peritoneal dialysis (34% versus 29% [0.11]), received a pre-emptive kidney transplant (4% vs 1% [0.19]), and were referred to specialist care < 3 months before treatment (25% vs 19% [0.15]) than Maori patients. Fewer non-Maori started dialysis with a non-tunnelled dialysis vascular catheter (43% versus 47% [- 0.08]). The indigenous-age standardised incidence rate ratio for non-Maori commencing renal replacement therapy in 2011 was 0.50 (95% CI, 0.40 0.61) compared with Maori. Propensity score matching generated cohorts with similar characteristics, although non-Maori less frequently started dialysis with a non-tunnelled venous catheter (30% versus 47% [- 0.35]) or lived remotely (3% versus 14% [- 0.50]). In matched cohorts, non-Maori experienced lower all-cause mortality at 5 yr. after commencement of treatment (risk ratio 0.78, 95% CI 0.72 0.84). New Zealand European patients experienced lower mortality than Maori patients in indigenous age-standardised analyses (age-standardised mortality rate ratio 0.58, 95% CI 0.51-0.67). CONCLUSIONS: Non-Maori patients are treated with temporary dialysis vascular access less often than Maori, and experience longer life expectancy with dialysis, even when socioeconomic, demographic, and geographical factors are equivalent. Based on these disparities, health services should monitor and address inequitable treatment practices and outcomes in end stage kidney disease care. PMID- 29458365 TI - Temporal changes in genetic diversity of msp-1, msp-2, and msp-3 in Plasmodium falciparum isolates from Grande Comore Island after introduction of ACT. AB - BACKGROUND: Malaria is still one of the serious public health problems in Grande Comore Island, although the number of annual cases has been greatly reduced in recent years. A better understanding of malaria parasite population diversity and transmission dynamics is critical for assessing the effectiveness of malaria control measures. The objective of this study is to investigate temporal changes in genetic diversity of Plasmodium falciparum populations and multiplicity of infection (MOI) in Grande Comore 10 years after introduction of ACT. METHODS: A total of 232 P. falciparum clinical isolates were collected from the Grande Comore Island during two sampling periods (118 for 2006-2007 group, and 114 for 2013-2016 group). Parasite isolates were characterized for genetic diversity and complexity of infection by genotyping polymorphic regions in merozoite surface protein gene 1 (msp-1), msp-2, and msp-3 using nested PCR and DNA sequencing. RESULTS: Three msp-1 alleles (K1, MAD20, and RO33), two msp-2 alleles (FC27 and 3D7), and two msp-3 alleles (K1 and 3D7) were detected in parasites of both sampling periods. The RO33 allele of msp-1 (84.8%), 3D7 allele of msp-2 (90.8%), and K1 allele of msp-3 (66.7%) were the predominant allelic types in isolates from 2006-2007 group. In contrast, the RO33 allele of msp-1 (63.4%), FC27 allele of msp-2 (91.1%), and 3D7 allele of msp-3 (53.5%) were the most prevalent among isolates from the 2013-2016 group. Compared with the 2006-2007 group, polyclonal infection rates of msp-1 (from 76.7 to 29.1%, P < 0.01) and msp-2 (from 62.4 to 28.3%, P < 0.01) allelic types were significantly decreased in those from 2013 2016 group. Similarly, the MOIs for both msp-1 and msp-2 were higher in P. falciparum isolates in the 2006-2007 group than those in 2013-2016 group (MOI = 3.11 vs 1.63 for msp-1; MOI = 2.75 vs 1.35 for msp-2). DNA sequencing analyses also revealed reduced numbers of distinct sequence variants in the three genes from 2006-2007 to 2013-2016: msp-1, from 32 to 23 (about 28% decline); msp-2 from 29 to 21 (about 28% decline), and msp-3 from 11 to 3 (about 72% decline). CONCLUSIONS: The present data showed dramatic reduction in genetic diversity and MOI among Grande Comore P. falciparum populations over the course of the study, suggesting a trend of decreasing malaria transmission intensity and genetic diversity in Grande Comore Island. These data provide valuable information for surveillance of P. falciparum infection and for assessing the appropriateness of the current malarial control strategies in the endemic area. PMID- 29458367 TI - The rs1024611 in the CCL2 gene and risk of gynecological cancer in Asians: a meta analysis. AB - BACKGROUND: The -2518A/G (rs1024611) polymorphism of the CCL2 (C-C motif chemokine ligand 2), also known as MCP-1 (monocyte chemotactic protein-1) gene, has been reported to be associated with increased gynecological cancer risk, but the results are conflicting. METHODS: In this analysis, 1089 cases and 1553 controls from six publications were used to investigate the association between CCL2-2518A/G (rs1024611) polymorphism and the risk of gynecological cancer with a meta-analytic approach. Studies published on EBSCO, EMBASE, Web of Science, PubMed, SpringerLink, ScienceDirect, Weipu, and CNKI databases were identified (last update was on November 3, 2015). Six articles focused on the association between CCL2-2518A/G (rs1024611) polymorphism, and gynecological cancer risk was selected and data were extracted. The cancer type included endometrial cancer (n = 1), breast cancer (n = 2), ovarian cancer (n = 2), and cervical cancer (n = 1). All statistical analyses were performed using the STATA version 12.0 software. RESULTS: The meta-analysis showed that CCL2-2518A/G (rs1024611) polymorphism is associated with risk of gynecological cancer (GG vs AG + AA, OR = 1.55, 95%CI = 1.07-2.24, P < 0.05; AA vs GG, OR = 0.59 95%CI = 0.38-0.92, P < 0.05). Notably, the subgroup analysis demonstrated that the genotype AA is associated with a reduced gynecological cancer risk in Asians, but an increased risk when compared to AG in Europeans. CONCLUSIONS: Our data demonstrated the CCL2-2518A/G (rs1024611) polymorphism is significantly associated with risk of gynecological cancer, and the association differs by ethnicity. PMID- 29458368 TI - Report from the 3rd Cardiovascular Outcome Trial (CVOT) Summit of the Diabetes & Cardiovascular Disease (D&CVD) EASD Study Group. AB - The 3rd Cardiovascular Outcome Trial Summit of the Diabetes & Cardiovascular Disease EASD Study Group was held on the 26-27 October 2017 in Munich. As in 2015 and 2016, this summit was organised in light of recently completed and published CVOTs on diabetes, aiming to serve as a reference meeting for in-depth discussions on the topic. Amongst others, the CVOTs EXSCEL, DEVOTE, the CANVAS program and the ACE-trial, which released primary outcome results in 2017, were discussed. Trial implications for diabetes management and recent perspectives of diabetologists, cardiologists, endocrinologists, nephrologists and general practitioners were highlighted. The clinical relevance of cardiovascular outcome trials and its implications regarding reimbursement were compared with real-world studies. The 4th Cardiovascular Outcome Trial Summit will be held in Munich 25-26 October 2018 ( http://www.dcvd.org ). PMID- 29458369 TI - Is fasting safe? A chart review of adverse events during medically supervised, water-only fasting. AB - BACKGROUND: Evidence suggests that fasting, during which only water is consumed, results in potentially health promoting physiological effects. However, peer reviewed research assessing the safety of water-only fasting is lacking. To address this, we conducted a chart review to describe adverse events (AEs) that occurred during medically supervised, water-only fasting. METHODS: Electronic charts from patient visits to a residential medical facility from 2006 to 2011 were reviewed. Patients who were at least 21 years of age and water-only fasted for >=2 consecutive days with a refeeding period equal to half of the fast length were included. Out of 2539 charts, 768 visits met our inclusion and exclusion criteria. AEs were abstracted from chart notes and classified according to CTCAE (v4.03) and MedDRA (v12.1) terminology. Descriptive analysis of AEs is reported. RESULTS: During the protocol period, the highest grade AE (HGAE) in 555 visits was a grade 2 event or lower, in 212 visits it was a grade 3 event, in 1 visit it was a grade 4 event, and there were no grade 5 events. There were 2 (0.002%) visits with a serious adverse event (SAE). The majority of AEs identified were mild (n = 4490, 75%) in nature and known reactions to fasting. CONCLUSIONS: To our knowledge, this is the most comprehensive analysis of AEs experienced during medically supervised, water-only fasting conducted to date. Overall, our data indicate that the majority of AEs experienced were mild to moderate and known reactions to fasting. This suggests that the protocol used in this study can be safely implemented in a medical setting with minimal risk of a SAE. PMID- 29458370 TI - The critical roles of activated stellate cells-mediated paracrine signaling, metabolism and onco-immunology in pancreatic ductal adenocarcinoma. AB - Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal malignant diseases worldwide. It is refractory to conventional treatments, and consequently has a documented 5-year survival rate as low as 7%. Increasing evidence indicates that activated pancreatic stellate cells (PSCs), one of the stromal components in tumor microenvironment (TME), play a crucial part in the desmoplasia, carcinogenesis, aggressiveness, metastasis associated with PDAC. Despite the current understanding of PSCs as a "partner in crime" to PDAC, detailed regulatory roles of PSCs and related microenvironment remain obscure. In addition to multiple paracrine signaling pathways, recent research has confirmed that PSCs mediated tumor microenvironment may influence behaviors of PDAC via diverse mechanisms, such as rewiring metabolic networks, suppressing immune responses. These new activities are closely linked with treatment and prognosis of PDAC. In this review, we discuss the recent advances regarding new functions of activated PSCs, including PSCs-cancer cells interaction, mechanisms involved in immunosuppressive regulation, and metabolic reprogramming. It's clear that these updated experimental or clinical studies of PSCs may provide a promising approach for PDAC treatment in the near future. PMID- 29458371 TI - Mechanisms of rapid cancer cell reprogramming initiated by targeted receptor tyrosine kinase inhibitors and inherent therapeutic vulnerabilities. AB - Receptor tyrosine kinase (RTK) pathways serve as frequent oncogene drivers in solid cancers and small molecule and antibody-based inhibitors have been developed as targeted therapeutics for many of these oncogenic RTKs. In general, these drugs, when delivered as single agents in a manner consistent with the principles of precision medicine, induce tumor shrinkage but rarely complete tumor elimination. Moreover, acquired resistance of treated tumors is nearly invariant such that monotherapy strategies with targeted RTK drugs fail to provide long-term control or cures. The mechanisms mediating acquired resistance in tumors at progression treated with RTK inhibitors are relatively well defined compared to the molecular and cellular understanding of the cancer cells that persist early on therapy. We and others propose that these persisting cancer cells, termed "residual disease", provide the reservoir from which acquired resistance eventually emerges. Herein, we will review the literature that describes rapid reprogramming induced upon inhibition of oncogenic RTKs in cancer cells as a mechanism by which cancer cells persist to yield residual disease and consider strategies for disrupting these intrinsic responses for future therapeutic gain. PMID- 29458372 TI - Relationship of CT-quantified emphysema, small airways disease and bronchial wall dimensions with physiological, inflammatory and infective measures in COPD. AB - BACKGROUND: COPD is a complex, heterogeneous disease characterised by progressive development of airflow limitation. Spirometry provides little information about key aspects of pathology and is poorly related to clinical outcome, so other tools are required to investigate the disease. We sought to explore the relationships between quantitative CT analysis with functional, inflammatory and infective assessments of disease to identify the utility of imaging to stratify disease to better predict outcomes and disease response. METHODS: Patients from the AERIS study with moderate-very severe COPD underwent HRCT, with image analysis determining the quantity of emphysema (%LAA<- 950), small airways disease (E/I MLD) and bronchial wall thickening (Pi10). At enrolment subjects underwent lung function testing, six-minute walk testing (6MWT), blood sampling for inflammatory markers and sputum sampling for white cell differential and microbiological culture and PCR. RESULTS: 122 subjects were included in this analysis. Emphysema and small airways disease had independent associations with airflow obstruction (beta = - 0.34, p < 0.001 and beta = - 0.56, p < 0.001). %LAA<- 950 had independent associations with gas transfer (beta = - 0.37, p < 0.001) and E/I MLD with RV/TLC (beta = 0.30, p =0.003). The distance walked during the 6MWT was not associated with CT parameters, but exertional desaturation was independently associated with emphysema (beta = 0.73, p < 0.001). Pi10 did not show any independent associations with lung function or functional parameters. No CT parameters had any associations with sputum inflammatory cells. Greater emphysema was associated with lower levels of systemic inflammation (CRP beta = - 0.34, p < 0.001 and fibrinogen beta = - 0.28, p =0.003). There was no significant difference in any of the CT parameters between subjects where potentially pathogenic bacteria were detected in sputum and those where it was not. CONCLUSIONS: This study provides further validation for the use of quantitative CT measures of emphysema and small airways disease in COPD as they showed strong associations with pulmonary physiology and functional status. In contrast to this quantitative CT measures showed few convincing associations with biological measures of disease, suggesting it is not an effective tool at measuring disease activity. PMID- 29458373 TI - Using PROMIS for measuring recovery after abdominal surgery: a pilot study. AB - BACKGROUND: To assess the construct validity and responsiveness of the PROMIS Physical Function v1.2 short form 8b (PROMIS-PF), and the PROMIS Ability to Participate in Social Roles and Activities v2.0 short form 8a (PROMIS-APS) in postoperative recovery. METHODS: An observational pilot study was conducted in which 30 patients participated, undergoing various forms of abdominal surgery. Patients completed the PROMIS-PF and PROMIS-APS, the Short Form 36 Health Survey (SF-36) and the World Health Organization Disability Assessment Schedule 2.0 (WHODAS) at several time points before and after surgery. The construct validity and responsiveness of the two PROMIS short forms were evaluated by testing pre defined hypotheses and were considered adequate when at least 75% of the data was consistent with the hypotheses. Construct validity was evaluated by calculating Spearman correlations and the responsiveness by calculating effect sizes. RESULTS: 6/7 (85.7%) of the results were consistent with the hypotheses supporting the construct validity of the PROMIS-PF. For the PROMIS-APS this was the case in 7/15 (46.7%) of the results. For the PROMIS-PF, 6/7 (85.7%) of the results were consistent with the hypotheses, supporting responsiveness. Regarding the responsiveness of the PROMIS-APS, only 7 out of 13 (53.8%) of these results were consistent with the hypotheses. CONCLUSIONS: This study supported the construct validity and the responsiveness of the PROMIS-PF v1.2 short form 8b for measuring recovery in abdominal surgery. Considering the major advantages of PROMIS, we recommend the use of the PROMIS-PF in abdominal surgery. PMID- 29458374 TI - New insights into long noncoding RNAs and their roles in glioma. AB - Glioma is one of the most prevalent types of primary intracranial carcinoma with varying malignancy grades I-IV and histological subtypes, including astrocytomas, glioblastoma multiform (GBM), oligodendrogliomas and mixed tumors. Glioma is characterized by rapid cell proliferation and angiogenesis, and the WHO grade IV glioblastoma, which is highly malignant with poor prognosis because GBM stem-like cells (GSCs) are resistant to conventional therapy and easily recrudescent, accounts for the majority of gliomas. Consequently, investigations exploring the accurate molecular mechanisms and reliable therapeutic targets for gliomas have drawn extensive attention.Based on the increasing amount of functional lncRNAs aberrantly expressed in glioma tissues and cell lines, lncRNAs might be critical for glioma initiation, progression and other malignant phenotypes. This review summarizes the latest insights into the lncRNA field and their functional roles in glioma, therefore evaluating the potential clinical applications of lncRNAs as prospective novel biomarkers and therapeutic targets. PMID- 29458375 TI - Letter to editor: Blood pressure, hypertension and lead exposure. AB - A significant association of office diastolic blood pressure with low-level blood lead exposure was reported in a Brazilian adult population. However, caution should be taken to interpret these results. The multivariable-adjusted association with blood pressure was positive for diastolic blood pressure, but inverse for systolic blood pressure. The association sizes were infinitesimal without clinical relevance. The outcome measures, i.e. blood pressure and the prevalence of hypertension were analysed across categories of the blood lead distribution - not in relation to blood lead as continuous variable. Blood pressure was the average of two oscillometric office readings, whereas ambulatory monitoring is the state-of-the-art. PMID- 29458376 TI - High experienced continuity in breast cancer care is associated with high health related quality of life. AB - BACKGROUND: High experienced continuity is known to be associated with lower needs for supportive care and most likely higher quality of life. On this background, the aim of this study was to investigate if patient-experienced continuity of care was associated with health-related quality of life (HRQoL) in breast cancer patients treated at two different-sized breast cancer units. METHODS: In 2016, two questionnaires, "Statements on experienced continuity of care" and "The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30)", were sent out to patients diagnosed between 2011 and 2014 at two different-sized breast cancer units in Sweden. Lead times and other data reflecting medical quality were collected from the patients' medical records and from the National Swedish Breast Cancer Quality Register. RESULTS: Of 356 eligible patients, 231 (65%) answered the questionnaires, of whom 218 patients were included in the analyses. A statistically significant association was found between high experienced continuity and high global HRQoL (p = 0.03). Continuity was higher at the smaller unit, while no major differences between the units were found regarding medical quality or lead times. CONCLUSION: The study found that high experienced continuity and HRQoL was strongly associated. A statistically significant higher continuity of care was found at the smaller unit, in line with what was expected. The absence of clinically relevant differences in lead times and medical quality may indicate that continuity could be achieved without loss of quality.

PMID- 29458377 TI - Out-of-hospital cardiac arrest in the home: Can area characteristics identify at risk communities in the Republic of Ireland? AB - BACKGROUND: Internationally, the majority of out-of-hospital cardiac arrests where resuscitation is attempted (OHCAs) occur in private residential locations i.e. at home. The prospect of survival for this patient group is universally dismal. Understanding of the area-level factors that affect the incidence of OHCA at home may help national health planners when implementing community resuscitation training and services. METHODS: We performed spatial smoothing using Bayesian conditional autoregression on case data from the Irish OHCA register. We further corrected for correlated findings using area level variables extracted and constructed for national census data. RESULTS: We found that increasing deprivation was associated with increased case incidence. The methodology used also enabled us to identify specific areas with higher than expected case incidence. CONCLUSIONS: Our study demonstrates novel use of Bayesian conditional autoregression in quantifying area level risk of a health event with high mortality across an entire country with a diverse settlement pattern. It adds to the evidence that the likelihood of OHCA resuscitation events is associated with greater deprivation and suggests that area deprivation should be considered when planning resuscitation services. Finally, our study demonstrates the utility of Bayesian conditional autoregression as a methodological approach that could be applied in any country using registry data and area level census data. PMID- 29458379 TI - Factors associated with multiple barriers to access to primary care: an international analysis. AB - BACKGROUND: Disparities in access to primary care (PC) have been demonstrated within and between health systems. However, few studies have assessed the factors associated with multiple barriers to access occurring along the care-seeking process in different healthcare systems. METHODS: In this secondary analysis of the 2016 Commonwealth Fund International Health Policy Survey of Adults, access was represented through participant responses to questions relating to access barriers either before or after reaching the PC practice in 11 countries (Australia, Canada, France, Germany, Norway, the Netherlands, New Zealand, Sweden, Switzerland, the United Kingdom, and United States). The number of respondents in each country ranged from 1000 to 7000 and the response rates ranged from 11% to 47%. We used multivariable logistic regression models within each of eleven countries to identify disparities in response to the access barriers by age, sex, immigrant status, income and the presence of chronic conditions. RESULTS: Overall, one in five adults (21%) experienced multiple barriers before reaching PC practices. After reaching care, an average of 16% of adults had two or more barriers. There was a sixfold difference between nations in the experience of these barriers to access. Vulnerable groups experiencing multiple barriers were relatively consistent across countries. People with lower income were more likely to experience multiple barriers, particularly before reaching primary care practices. Respondents with mental health problems and those born outside the country displayed substantial vulnerability in terms of barriers after reaching care. CONCLUSION: A greater understanding of the multiple barriers to access to PC across the stages of the care-seeking process may help to inform planning and performance monitoring of disparities in access. Variation across countries may reveal organisational and system drivers of access, and inform efforts to improve access to PC for vulnerable groups. The cumulative nature of these barriers remains to be assessed. PMID- 29458380 TI - Prevalence of molecular markers of artemisinin and lumefantrine resistance among patients with uncomplicated Plasmodium falciparum malaria in three provinces in Angola, 2015. AB - BACKGROUND: Artemisinin-based combination therapy is the first-line anti-malarial treatment for uncomplicated Plasmodium falciparum infection in Angola. To date, the prevalence of polymorphisms in the pfk13 gene, associated with artemisinin resistance, and pfmdr1, associated with lumefantrine resistance, have not been systematically studied in Angola. METHODS: DNA was isolated from pretreatment and late treatment failure dried blood spots collected during the 2015 round of therapeutic efficacy studies in Benguela, Lunda Sul, and Zaire Provinces in Angola. The pfk13 propeller domain and pfmdr1 gene were sequenced and analysed for polymorphisms. Pfmdr1 copy number variation was assessed using a real-time PCR method. The association between pfmdr1 and pfk13 mutations and treatment failure was investigated. RESULTS: The majority of pretreatment (99%, 466/469) and all late treatment failure (100%, 50/50) samples were wild type for pfk13. Three of the pretreatment samples (1%) carried the A578S mutation commonly observed in Africa and not associated with artemisinin resistance. All 543 pretreatment and day of late treatment failure samples successfully analysed for pfmdr1 copy number variation carried one copy of pfmdr1. The NYD haplotype was the predominant pfmdr1 haplotype, present in 63% (308/491) of pretreatment samples, followed by NFD, which was present in 32% (157/491) of pretreatment samples. The pfmdr1 N86 allele was overrepresented in day of late treatment failure samples from participants receiving artemether-lumefantrine (p value 0.03). CONCLUSIONS: The pretreatment parasites in patients participating in therapeutic efficacy studies in 2015 in Angola's three sentinel sites showed genetic evidence of susceptibility to artemisinins, consistent with clinical outcome data showing greater than 99% day 3 clearance rates. The lack of increased pfmdr1 copy number is consistent with previous reports from sub-Saharan Africa. Although pfmdr1 NYD and NFD haplotypes were overrepresented in artemether lumefantrine late treatment failure samples, their role as markers of resistance was unclear given that these haplotypes were also present in the majority of successfully treated patients in the artemether-lumefantrine treatment arms. PMID- 29458381 TI - Cardiac fluid dynamics meets deformation imaging. AB - Cardiac function is about creating and sustaining blood in motion. This is achieved through a proper sequence of myocardial deformation whose final goal is that of creating flow. Deformation imaging provided valuable contributions to understanding cardiac mechanics; more recently, several studies evidenced the existence of an intimate relationship between cardiac function and intra ventricular fluid dynamics. This paper summarizes the recent advances in cardiac flow evaluations, highlighting its relationship with heart wall mechanics assessed through the newest techniques of deformation imaging and finally providing an opinion of the most promising clinical perspectives of this emerging field. It will be shown how fluid dynamics can integrate volumetric and deformation assessments to provide a further level of knowledge of cardiac mechanics. PMID- 29458382 TI - Cost-effectiveness of the treatment of uncomplicated severe acute malnutrition by community health workers compared to treatment provided at an outpatient facility in rural Mali. AB - BACKGROUND: The Malian Nutrition Division of the Ministry of Health and Action Against Hunger tested the feasibility of integrating treatment of severe acute malnutrition (SAM) into the existing Integrated Community Case Management package delivered by community health workers (CHWs). This study assessed costs and cost effectiveness of CHW-delivered care compared to outpatient facility-based care. METHODS: Activity-based costing methods were used, and a societal perspective employed to include all relevant costs incurred by institutions, beneficiaries and communities. The intervention and control arm enrolled different numbers of children so a modelled scenario sensitivity analysis was conducted to assess the cost-effectiveness of the two arms, assuming equal numbers of children enrolled. RESULTS: In the base case, with unequal numbers of children in each arm, for CHW delivered care, the cost per child treated was 244 USD and cost per child recovered was 259 USD. Outpatient facility-based care was less cost-effective at 442 USD per child and 501 USD per child recovered. The conclusions of the analysis changed in the modelled scenario sensitivity analysis, with outpatient facility-based care being marginally more cost-effective (cost per child treated is 188 USD, cost per child recovered is 214 USD), compared to CHW-delivered care. This suggests that achieving good coverage is a key factor influencing cost effectiveness of CHWs delivering treatment for SAM in this setting. Per week of treatment, households receiving CHW-delivered care spent half of the time receiving treatment and three times less money compared with those receiving treatment from the outpatient facility. CONCLUSIONS: This study supports existing evidence that the delivery of treatment by CHWs is a cost-effective intervention, provided that good coverage is achieved. A major benefit of this strategy was the lower cost incurred by the beneficiary household when treatment is available in the community. Further research is needed on the implementation costs that would be incurred by the government to increase the operability of these results. PMID- 29458383 TI - Cumulative exposure to environmental pollutants during early pregnancy and reduced fetal growth: the Project Viva cohort. AB - BACKGROUND: Reduced fetal growth is associated with perinatal and later morbidity. Prenatal exposure to environmental pollutants is linked to reduced fetal growth at birth, but the impact of concomitant exposure to multiple pollutants is unclear. The purpose of this study was to examine interactions between early pregnancy exposure to cigarette smoke, traffic pollution, and select perfluoroalkyl substances (PFASs) on birth weight-for-gestational age (BW/GA). METHODS: Among 1597 Project Viva mother-infant pairs, we assessed maternal cigarette smoking by questionnaire, traffic pollution at residential address by black carbon land use regression model, and plasma concentration of select PFASs in early pregnancy. We calculated sex-specific BW/GA z-scores, an index of fetal growth, from national reference data. We fit covariate-adjusted multi-pollutant linear regression models and examined interactions between exposures, using a likelihood-ratio test to identify a best-fit model. RESULTS: Two hundred six (13%) mothers smoked during pregnancy. Mean [standard deviation (SD)] for black carbon was 0.8 (0.3) MUg/m3, perfluorooctane sulfonate (PFOS) was 29.1 (16.5) ng/mL, and BW/GA z-score was 0.19 (0.96). In the best-fit model, BW/GA z-score was lower in infants of mothers exposed to greater black carbon [- 0.08 (95% CI: -0.15, - 0.01) per interquartile range (IQR)]. BW/GA z-score (95% CI) was also lower in infants of mothers who smoked [- 0.09 (- 0.23, 0.06)] or were exposed to greater PFOS [- 0.03 (- 0.07, 0.02) per IQR], although confidence intervals crossed the null. There were no interactions between exposures. In secondary analyses, instead of PFOS, we examined perfluorononanoate (PFNA) [mean (SD): 0.7 (0.4) ng/mL], a PFAS more closely linked to lower BW/GA in our cohort. The best-fit multi-pollutant model included positive two-way interactions between PFNA and both black carbon and smoking (p-interactions = 0.03). CONCLUSIONS: Concurrent prenatal exposures to maternal smoking, black carbon, and PFOS are additively associated with lower fetal growth, whereas PFNA may attenuate associations of smoking and black carbon with lower fetal growth. It is important to examine interactions between multiple exposures in relation to health outcomes, as effects may not always be additive and may shed light on biological pathways. PMID- 29458384 TI - Cardiovascular cine imaging and flow evaluation using Fast Interrupted Steady State (FISS) magnetic resonance. AB - BACKGROUND: Existing cine imaging techniques rely on balanced steady-state free precession (bSSFP) or spoiled gradient-echo readouts, each of which has limitations. For instance, with bSSFP, artifacts occur from rapid through-plane flow and off-resonance effects. We hypothesized that a prototype cine technique, radial fast interrupted steady-state (FISS), could overcome these limitations. The technique was compared with standard cine bSSFP for cardiac function, coronary artery conspicuity, and aortic valve morphology. Given its advantageous properties, we further hypothesized that the cine FISS technique, in combination with arterial spin labeling (ASL), could provide an alternative to phase contrast for visualizing in-plane flow patterns within the aorta and branch vessels. MAIN BODY: The study was IRB-approved and subjects provided consent. Breath-hold cine FISS and bSSFP were acquired using similar imaging parameters. There was no significant difference in biplane left ventricular ejection fraction or cardiac image quality between the two techniques. Compared with cine bSSFP, cine FISS demonstrated a marked decrease in fat signal which improved conspicuity of the coronary arteries, while suppression of through-plane flow artifact on thin-slice cine FISS images improved visualization of the aortic valve. Banding artifacts in the subcutaneous tissues were reduced. In healthy subjects, dynamic flow patterns were well visualized in the aorta, coronary and renal arteries using cine FISS ASL, even when the slice was substantially thicker than the vessel diameter. CONCLUSION: Cine FISS demonstrates several benefits for cardiovascular imaging compared with cine bSSFP, including better suppression of fat signal and reduced artifacts from through-plane flow and off-resonance effects. The main drawback is a slight (~ 20%) decrease in temporal resolution. In addition, preliminary results suggest that cine FISS ASL provides a potential alternative to phase contrast techniques for in-plane flow quantification, while enabling an efficient, visually-appealing, semi-projective display of blood flow patterns throughout the course of an artery and its branches. PMID- 29458385 TI - De novo mast cell leukemia without CD25 expression and KIT mutations: a rare case report in a 13-year-old child. AB - BACKGROUND: Mast cell leukemia (MCL) is a very rare form of systemic mastocytosis (SM) and accounts for less than 0.5% of all mastocytosis. The diagnosis of MCL requires the presence of SM criteria, accompanied by leukemic infiltrating of atypical mast cells (MCs) in bone marrow (BM), peripheral blood as well as extracutaneous organs. MCL is a fatal disease that almost always behaves aggressively, and the median survival time is only about six months. Herein, we present a rare case of de novo MCL without CD25 expression and KIT mutations. CASE PRESENTATION: A previously healthy 13-year-old boy was referred to our hospital due to incidental discovery of an enlarged right tonsil. Diffuse infiltration of medium-sized hematopoietic blasts was found in his right tonsil, BM and multiple lymph nodes. The neoplastic cell population was subsequently revealed to exhibit differentiation towards the mast cell lineage by expressing CD117 and tryptase, but the cell population lacked expression of CD25/CD2 and the activating mutation of the KIT gene. An abnormal karyotype was identified, but no leukemia-associated fusion genes were found. Involvement of peripheral blood, bone and lung was subsequently demonstrated. The most important differential diagnosis included tryptase-positive (T+) acute myeloid leukemia, myelomastocytic leukemia and basophilic leukemia. The morphological characteristics and infiltrating patterns of the abnormal MCs supported the final diagnosis of MCL. Although intensive chemotherapy and allogeneic stem cell transplants were performed on the patient, he died 18 months after initial presentation. CONCLUSION: Due to its rarity, the diagnosis of MCL without typical immunophenotype and genetic aberrations is particularly challenging. Comprehensive investigation of clinical and pathological features to exclude other T+ myeloid neoplasms is necessary. PMID- 29458386 TI - Functional improvements in patients with lymphangioleiomyomatosis after sirolimus: an observational study. AB - BACKGROUND: Sirolimus has been shown to be effective in patients with lymphangioleiomyomatosis (LAM). We wish to summarize our experience using sirolimus and its effectiveness in LAM patients. METHODS: We analyzed data from 98 patients who were diagnosed with definite or probable sporadic LAM based on the European Respiratory Society diagnosis criteria for LAM in 2010 at Peking Union Medical College Hospital and who had received sirolimus during January 2007 to June 2015. The data before and after the initiation of sirolimus therapy included pulmonary function tests, arterial blood gas analysis, 6-min walking distance (6MWD), size of chylous effusion and renal angiomyolipomas (AML), St. George's Respiratory Questionnaires (SGRQ) and vascular endothelial growth factor D (VEGF-D) levels. Serum levels of sirolimus and adverse events were collected. RESULTS: Median follow-up was 2.5 years. Most patients had forced expiratory volume in 1 s (FEV1) values less than 70% predicted or symptomatic chylothorax. The mean changes before and after the initiation of sirolimus were - 31.12 +/- 30.78 mL/month and 16.11 +/- 36.00 mL/month (n = 18,p = 0.002) for FEV1 change, and - 0.55 +/- 0.60 mmHg/month and 0.30 +/- 1.19 mmHg/month (n = 17, p = 0.018) for PaO2 change. 6MWD improved from 358.8 +/- 114.4 m to 415.6 +/- 118.6 m (n = 46, p = 0.004) and SGRQ total score from 57.2 +/- 21.0 to 47.5 +/- 22.8 (n = 50, p < 0.001). The median VEGF-D concentration decreased to 1609.4 pg/mL from 3075.6 pg/mL after sirolimus therapy (n = 41, p < 0.001). Patients with sirolimus trough levels of 5-9.9 ng/mL had an increase in FEV1 (p < 0.05). Sixty-five percent of patients (13/20) had almost complete resolution of chylous effusions. The most frequent adverse events were mouth ulcers, menstrual disorder, hyperlipidemia and acneiform rash, all were mild. CONCLUSION: Long-term use of sirolimus is safe in patients with LAM. LAM patients with FEV1 less than 70% predicted and symptomatic chylothorax are suitable for receiving sirolimus therapy. The maintaining serum trough levels of sirolimus are recommended between 5 to 9.99 ng/mL.

PMID- 29458388 TI - A novel generation 1928zT2 CAR T cells induce remission in extramedullary relapse of acute lymphoblastic leukemia. AB - BACKGROUND: Anti-CD19 chimeric antigen receptor (CAR) T cells have shown promise in the treatment of B cell acute lymphocytic leukemia (B-ALL). However, its efficacy in B-ALL patients with extramedullary involvement is limited due to poor responses and neurotoxicity. Here, we utilized a third generation of CAR T cell vector, which contains the Toll/interleukin-1 receptor (ITR) domain of Toll-like receptor 2 (TLR2), to generate 1928zT2 T cells targeting CD19, and evaluated the efficacy of 1928zT2 T cells in relapse or refractory B-ALL patients with extramedullary involvement. METHODS: 1928zT2 T cells were generated by 19-28z TLR2 lentiviral vector transfection into primary human T lymphocytes. The anti leukemia effect of 1928zT2 T cells were determined by killing assays and in xenografts. Three patients diagnosed as relapse or refractory ALL with extramedullary involvement were infused with 1928zT2 T cells, and the clinical responses were evaluated by BM smear, B-ultrasonography, PET/CT, histology, flow cytometry, qPCR, ELISA, and luminex assay. RESULTS: 1928zT2 T cells exhibited enhanced effector function against CD19+ leukemic cells in vitro and in a xenograft model of human extramedullary leukemia. Notably, the 1928zT2 T cells eradicated extramedullary leukemia and induced complete remission in the three relapse and refractory ALL patients without serious adverse effects. 1928zT2 T cells expanded robustly in the circulation of these three patients and were detected in the cerebrospinal fluid of patient 3. These three patients experienced cytokine release syndrome (CRS) with grade 2 or 3, which remitted spontaneously or after tocilizumab treatment. None of the three patients suffered neurotoxicity or needed further intensive care. CONCLUSIONS: Our results demonstrate that 1928zT2 T cells with TLR2 incorporation augment anti-leukemic effects, particularly for eradicating extramedullary leukemia cells, and suggest that the infusion of 1928zT2 T cells is an encouraging treatment for relapsed/refractory ALL patients with extramedullary involvement. TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT02822326 . Date of registration: July 4, 2016. PMID- 29458389 TI - Artesunate shows potent anti-tumor activity in B-cell lymphoma. AB - BACKGROUND: Although chemo-immunotherapy has led to an improved overall survival for most B-cell lymphoma types, relapsed and refractory disease remains a challenge. The malaria drug artesunate has previously been identified as a growth suppressor in some cancer types and was tested as a new treatment option in B cell lymphoma. METHODS: We included artesunate in a cancer sensitivity drug screen in B lymphoma cell lines. The preclinical properties of artesunate was tested as single agent in vitro in 18 B-cell lymphoma cell lines representing different histologies and in vivo in an aggressive B-cell lymphoma xenograft model, using NSG mice. Artesunate-treated B lymphoma cell lines were analyzed by functional assays, gene expression profiling, and protein expression to identify the mechanism of action. RESULTS: Drug screening identified artesunate as a highly potent anti-lymphoma drug. Artesunate induced potent growth suppression in most B lymphoma cells with an IC50 comparable to concentrations measured in serum from artesunate-treated malaria patients, while leaving normal B-cells unaffected. Artesunate markedly inhibited highly aggressive tumor growth in a xenograft model. Gene expression analysis identified endoplasmic reticulum (ER) stress and the unfolded protein response as the most affected pathways and artesunate-induced expression of the ER stress markers ATF-4 and DDIT3 was specifically upregulated in malignant B-cells, but not in normal B-cells. In addition, artesunate significantly suppressed the overall cell metabolism, affecting both respiration and glycolysis. CONCLUSIONS: Artesunate demonstrated potent apoptosis-inducing effects across a broad range of B-cell lymphoma cell lines in vitro, and a prominent anti-lymphoma activity in vivo, suggesting it to be a relevant drug for treatment of B-cell lymphoma. PMID- 29458390 TI - FAK-ERK activation in cell/matrix adhesion induced by the loss of apolipoprotein E stimulates the malignant progression of ovarian cancer. AB - BACKGROUND: Extracellular matrix (ECM) is a mediator of tumor progression. However, whether the alterations of the intraperitoneal ECM prior to tumor establishment affects the malignant progression of ovarian cancer remains elusive. METHODS: Apolipoprotein (ApoE) knock-out mice was used to analyze the intraperitoneal ECM alterations by quantification of the major components of ECM. ID8 cells were implanted in vivo to generate allografts and human ovarian cancer cell lines were characterized in vitro to assess the effects of ECM alterations on the malignant progression of ovarian cancer. Adhesion assay, immunochemistry, cytokines profile, proliferation assay, transwell invasion assay and western blot were used to determine the malignant phenotype of ovarian cancer cells. RESULTS: ApoE loss induced increased ECM deposition, which stimulated the adhesions of ovarian cancer cells. The adhesion-mediated focal adhesion kinase (FAK) signaling enhanced the invasive behaviors of ovarian cancer cells through activation of a ERK-MMP linkage. This ECM-induced signaling cascade was further confirmed in human ovarian cancer cell lines in vitro. Furthermore, reversal of the ECM accumulation with BAPN or abrogation of adhesion-induced ERK activation in ovarian cancer cells with MEK inhibitors (MEKi) was found to effectively delay ovarian cancer progression. CONCLUSIONS: These findings identify the FAK-ERK activation in cell/matrix adhesion in the malignant progression of ovarian cancer and the efficiency of BAPN or MEKi for tumor suppression, providing an impetus for further studies to explore the possibility of new anticancer therapeutic combinations. PMID- 29458391 TI - Down-regulation of ghrelin receptors on dopaminergic neurons in the substantia nigra contributes to Parkinson's disease-like motor dysfunction. AB - Ghrelin exerts a wide range of physiological actions throughout the body and appears to be a promising target for disease therapy. Endogenous ghrelin receptors (GHSRs) are present in extrahypothalamic sites including the substantia nigra pars compacta (SNc), which is related to phenotypic dysregulation or frank degeneration in Parkinson's disease (PD). Here we found a dramatic decrease in the expression of GHSR in PD-specific induced pluripotent stem cell (iPSC) derived dopaminergic (DAnergic) neurons generated from patients carrying parkin gene (PARK2) mutations compared to those from healthy controls. Consistently, a significant decrease in the expression of GHSR was found in DAnergic neurons of isogenic PARK2-iPSC lines that mimicked loss of function of the PARK2 gene through CRISPR Cas9 technology. Furthermore, either intracerebroventricular injection or microinjection into the SNc of the selective GHSR1a antagonist [D Lys3]-GHRP6 in normal mice produced cataleptic behaviors related to dysfunction of motor coordination. These findings suggest that the down-regulation of GHSRs in SNc-DA neurons induced the initial dysfunction of DA neurons, leading to extrapyramidal disorder under PD. PMID- 29458392 TI - Recruitment of older adults to three preventative lifestyle improvement studies. AB - BACKGROUND: Recruiting isolated older adults to clinical trials is complex, time consuming and difficult. Previous studies have suggested querying existing databases to identify appropriate potential participants. We aim to compare recruitment techniques (general practitioner (GP) mail-outs, community engagement and clinician referrals) used in three randomised controlled trial (RCT) studies assessing the feasibility or effectiveness of two preventative interventions in isolated older adults (the Lifestyle Matters and Putting Life In Years interventions). METHODS: During the three studies (the Lifestyle Matters feasibility study, the Lifestyle Matters RCT, the Putting Life In Years RCT) data were collected about how participants were recruited. The number of letters sent by GP surgeries for each study was recorded. In the Lifestyle Matters RCT, we qualitatively interviewed participants and intervention facilitators at 6 months post randomisation to seek their thoughts on the recruitment process. RESULTS: Referrals were planned to be the main source of recruitment in the Lifestyle Matters feasibility study, but due to a lack of engagement from district nurses, community engagement was the main source of recruitment. District nurse referrals and community engagement were also utilised in the Lifestyle Matters and Putting Life In Years RCTs; both mechanisms yielded few participants. GP mail-outs were the main source of recruitment in both the RCTs, but of those contacted, recruiting yield was low (< 3%). Facilitators of the Lifestyle Matters intervention questioned whether the most appropriate individuals had been recruited. Participants recommended that direct contact with health professionals would be the most beneficial way to recruit. CONCLUSIONS: Recruitment to the Lifestyle Matters RCT did not mirror recruitment to the feasibility study of the same intervention. Direct district nurse referrals were not effective at recruiting participants. The majority of participants were recruited via GP mail outs, which may have led to isolated individuals not being recruited to the trials. Further research is required into alternative recruitment techniques, including respondent-driven sampling plus mechanisms which will promote health care professionals to recruit vulnerable populations to research.

PMID- 29458394 TI - Twitter use at the 2016 Conference on the Science of Dissemination and Implementation in Health: analyzing #DIScience16. AB - BACKGROUND: Poor dissemination of research findings may hamper the reach and impact of scientific discoveries. One key emerging platform for research dissemination is social media, including Twitter. While Twitter and other social media are increasingly being used to disseminate research content presented during scientific conferences, few studies have investigated the extent to which these tools are used throughout conferences and how they are being used. The aim for this study was to better understand the use of Twitter during the 2016 Annual Conference on the Science of Dissemination and Implementation in Health (D&I conference). METHODS: We performed an analysis of Twitter use before, during, and after the 2016 D&I conference, which took place from December 14 to 15. All tweets (posted between December 1 and 31) that included the conference-specific hashtag (#DIScience16) were assessed. We identified 2639 tweets using the data analytics platform NUVI. We used NUVI software to generate statistics about reach, influence, mentions, and origin of the tweets. Individual tweet content was also assessed using DiscoverText and coded for disease category, implementation outcomes discussed, category of tweet, and conference track. RESULTS: A total of 2639 tweets were analyzed; 89.1% of the tweets were posted during the conference. A total of 389 unique users participated on Twitter, representing 31 states and 22 locations outside of the USA. Most (56.8%) tweets were re-tweets and were used for scientific promotion (50.6%). Key conference speakers and implementation outcomes (de-implementation, adaptation, and fidelity) were commonly discussed. CONCLUSIONS: Our findings reveal that Twitter was used as a platform during the D&I conference, both to facilitate conference discussion and to promote scientific ideas. This work contributes to the existing data analytics and implementation science literature in two major ways: (1) by advancing knowledge of how social media is used during annual academic conferences and (2) by providing a deeper understanding of themes and emerging areas of interest in the dissemination and implementation sciences. Knowing specific topics of interest can help planners and scientists better understand the landscape of current and future implementation research and encourage new research dissemination strategies. PMID- 29458393 TI - Dominant integration locus drives continuous diversification of plant immune receptors with exogenous domain fusions. AB - BACKGROUND: The plant immune system is innate and encoded in the germline. Using it efficiently, plants are capable of recognizing a diverse range of rapidly evolving pathogens. A recently described phenomenon shows that plant immune receptors are able to recognize pathogen effectors through the acquisition of exogenous protein domains from other plant genes. RESULTS: We show that plant immune receptors with integrated domains are distributed unevenly across their phylogeny in grasses. Using phylogenetic analysis, we uncover a major integration clade, whose members underwent repeated independent integration events producing diverse fusions. This clade is ancestral in grasses with members often found on syntenic chromosomes. Analyses of these fusion events reveals that homologous receptors can be fused to diverse domains. Furthermore, we discover a 43 amino acid long motif associated with this dominant integration clade which is located immediately upstream of the fusion site. Sequence analysis reveals that DNA transposition and/or ectopic recombination are the most likely mechanisms of formation for nucleotide binding leucine rich repeat proteins with integrated domains. CONCLUSIONS: The identification of this subclass of plant immune receptors that is naturally adapted to new domain integration will inform biotechnological approaches for generating synthetic receptors with novel pathogen "baits."

AB - BACKGROUND: 5-Fluorouracil (5-FU) remains the most widely used agent to treat colorectal cancer (CRC). However, its clinical efficacy is currently limited by the development of drug resistance. Traditional Chinese Herbal Medicine (TCM) has been shown to enhance the efficacy of standard anticancer agents. However, there are only a limited number of well-controlled preclinical and clinical studies documenting the potential benefit of TCM. Herein, we screened a series of TCM formulas in in vitro and in vivo animal models to identify biologically active formulas that were effective against CRC. METHODS: Cell proliferation and clonogenic assays, cell cycle analysis, immunoblot analysis and qRT-PCR were performed to investigate the mechanism(s) of action of the most active formula Huang-Qin-Ge-Gen-Tang (HQGGT) on growth of human CRC cells. In vivo animal models were used to document the antitumor activity of HQGGT alone and HQGGT in combination with 5-FU. RESULTS: We identified HQGGT, which suppressed the in vivo growth of human colon cancer HT-29 xenografts without associated toxicities. HQGGT displayed anti-proliferative activity against a wide range of CRC cell lines. This growth suppression correlated with induction of apoptosis. HQGGT enhanced the cytotoxicity of 5-FU against human 5-FU-resistant cells (H630R1) and mouse colon cancer cells (MC38). Our studies showed that the mechanism of action of this synergism was the result of suppression of thymidylate synthase (TS) expression by HQGGT. We analyzed different batches of HQGGT and observed consistent chemical fingerprints and biological activity. Finally, we show that orally administered HQGGT significantly enhanced the antitumor effect of 5-FU in mice bearing MC38 xenografts. CONCLUSIONS: These findings provide support for the potential role of HQGGT as a novel modulator of fluoropyrimidine chemotherapy in the treatment of CRC. PMID- 29458396 TI - Evaluation of heat-treating heartworm-positive canine serum samples during treatment with Advantage Multi(r) for Dogs and doxycycline. AB - BACKGROUND: The use of heat-treatment in canine and feline serum has been hypothesized to break the formation of antigen-antibody complexes, thereby freeing the heartworm antigen allowing for detection by commercially available heartworm antigen kits. While studies have analyzed the effect of heat-treating serum and plasma samples in the detection of heartworm antigen, these studies have not utilized necropsy verified results for validation. This study evaluated the use of heat-treating serum samples in experimentally infected dogs during adulticidal treatment in comparison with necropsy adult heartworm recovery. METHODS: As part of a primary study, a total of 16 dogs were experimentally infected with 16 sexually mature adult heartworms using surgical transplantation, allocating 8 dogs in both the control and treated group. Treated dogs received 10 months of topical administration of Advantage Multi(r) for Dogs (10% Imidacloprid + 2.5% Moxidectin) every 4 weeks and 30 days of 10 mg/kg doxycycline BID. Blood samples were collected from all study animals prior to surgical transplantation of adult heartworms, on study days 0, 1, 3, 7, 14, 21, 28, and every 4 weeks thereafter for the duration of this study. Concentration of heartworm antigen was tested using the DiroCHEK(r) heartworm antigen test kit using serum samples both pre- and post-heat-treatment. Serum samples were heat-treated at 103 degrees C in a dry heat block for 10 min and centrifuging at 1818* g for 20 min. RESULTS: There were a total of 4 instances (days 56, 140, 224 and 252) in 3 treated dogs in which a serum sample converted from negative for the detection of heartworm antigen prior to heat-treatment to positive for the detection of heartworm antigen post-heat-treatment. At necropsy, these dogs had no adult heartworms recovered and were all negative on antigen testing prior to and after heat treatment. There was 100% accuracy in the detection of either no infection, or 1 2 adult heartworm infections using the DiroCHEK in serum samples with and without heat-treatment at the time of necropsy. CONCLUSIONS: The DiroCHEK accurately diagnosed all dogs with live adults recovered at necropsy as heartworm antigen positive and all those dogs with no live adults recovered at necropsy as heartworm antigen negative without the use of heat-treatment for samples taken on the day of necropsy. Therefore, these results indicate that the use of heat treating serum samples did not provide data of any additional value in the diagnosis of heartworm-positive dogs receiving treatment in this study. Additionally, these results may indicate that the conversion of serum samples from negative to positive for the presence of heartworm antigen with heat treatment may not always accurately diagnose live adult heartworm infections since no adult heartworms were recovered at necropsy for those dogs in which a conversion event occurred. These conversion events may be detecting residual antigen leftover after all adult worms have died or may even be detecting off- target antigens, which have been denatured during heat-treatment. While a necropsy was not performed at the time of the conversion events, no live adult worms were recovered from any of the dogs in which a conversion event occurred earlier in treatment. PMID- 29458397 TI - Human arm joints reconstruction algorithm in rehabilitation therapies assisted by end-effector robotic devices. AB - BACKGROUND: End-effector robots are commonly used in robot-assisted neuro rehabilitation therapies for upper limbs where the patient's hand can be easily attached to a splint. Nevertheless, they are not able to estimate and control the kinematic configuration of the upper limb during the therapy. However, the Range of Motion (ROM) together with the clinical assessment scales offers a comprehensive assessment to the therapist. Our aim is to present a robust and stable kinematic reconstruction algorithm to accurately measure the upper limb joints using only an accelerometer placed onto the upper arm. METHODS: The proposed algorithm is based on the inverse of the augmented Jaciobian as the algorithm (Papaleo, et al., Med Biol Eng Comput 53(9):815-28, 2015). However, the estimation of the elbow joint location is performed through the computation of the rotation measured by the accelerometer during the arm movement, making the algorithm more robust against shoulder movements. Furthermore, we present a method to compute the initial configuration of the upper limb necessary to start the integration method, a protocol to manually measure the upper arm and forearm lengths, and a shoulder position estimation. An optoelectronic system was used to test the accuracy of the proposed algorithm whilst healthy subjects were performing upper limb movements holding the end effector of the seven Degrees of Freedom (DoF) robot. In addition, the previous and the proposed algorithms were studied during a neuro-rehabilitation therapy assisted by the 'PUPArm' planar robot with three post-stroke patients. RESULTS: The proposed algorithm reports a Root Mean Square Error (RMSE) of 2.13cm in the elbow joint location and 1.89cm in the wrist joint location with high correlation. These errors lead to a RMSE about 3.5 degrees (mean of the seven joints) with high correlation in all the joints with respect to the real upper limb acquired through the optoelectronic system. Then, the estimation of the upper limb joints through both algorithms reveal an instability on the previous when shoulder movement appear due to the inevitable trunk compensation in post-stroke patients. CONCLUSIONS: The proposed algorithm is able to accurately estimate the human upper limb joints during a neuro rehabilitation therapy assisted by end-effector robots. In addition, the implemented protocol can be followed in a clinical environment without optoelectronic systems using only one accelerometer attached in the upper arm. Thus, the ROM can be perfectly determined and could become an objective assessment parameter for a comprehensive assessment. PMID- 29458398 TI - Phlebotomine sand flies (Diptera: Psychodidae) in the Greek Aegean Islands: ecological approaches. AB - BACKGROUND: Blood-sucking phlebotomine sand flies are the vectors of the protozoan parasites Leishmania spp. Different Phlebotomus species transmit different Leishmania species causing leishmaniases which are neglected diseases emerging/reemerging in new regions. Thirteen sand fly species, ten belonging to the medically important genus Phlebotomus and three belonging to Sergentomyia are known in Greece. An increasing number of human and dog cases are reported each year from all parts of the country including the Aegean Islands. However, no previous study has been conducted on the sand fly fauna on the islands, except for Rhodes and Samos. The aim of this study was to investigate sand fly species in eleven small Aegean islands; to understand species-specific relationships with environmental and climatic factors and to compare sand fly community parameters among islands. A risk analysis was carried out for each species using climatic and environmental variables. RESULTS: Nine sand fly species: Phlebotomus neglectus, P. tobbi, P. similis, P. simici, P. perfiliewi, P. alexandri, P. papatasi, Sergentomyia minuta and S. dentata, were collected from the islands studied. Phlebotomus (Adlerius) sp. and Sergentomyia sp. specimens were also collected but not identified to the species level. There was a positive effect of distance from the sea on the abundance of P. neglectus, S. minuta and S. dentata, and a negative effect on the abundance of P. tobbi, P. simici and P. similis. In general, temperature preferences of sand fly populations were between 21 and 29 degrees C. Nevertheless, there were significant differences in terms of temperature and relative humidity preference ranges among species. The most important species found, P. neglectus, was indisputably the most adapted species in the study area with a very high reaction norm, favoring even the lower temperature and humidity ranges. Overall, the sand fly fauna in the islands was very rich but there were differences in species diversity, as indicated by the values of the Shannon-Wiener index, along with evenness and richness of the sand fly fauna between the islands and altitude ranges in the islands. CONCLUSIONS: The study indicated that the Greek Aegean Islands, however small, maintain a rich sand fly fauna. This includes important vectors of Leishmania spp. representing a risk for parasite transmission to humans and dogs along with the danger of maintaining new Leishmania spp. if introduced to the area. PMID- 29458400 TI - Towards an appropriate framework to facilitate responsible inclusion of pregnant women in drug development programs. AB - Evidence-based treatment for pregnant women will ultimately require research conducted in the population of pregnant women. Currently, few scholars have addressed the issue of responsible inclusion of pregnant women in drug research. Because of additional risks associated with including pregnant women in drug research and the altered ways in which drugs are processed by the pregnant body, pregnant women cannot be treated as an ordinary subgroup in the various phases of drug development. Instead, responsible inclusion of pregnant women requires careful design and planning of research for pregnant women specifically. Knowledge about these aspects is virtually nonexistent. In this article, we present a practical framework for the responsible inclusion of pregnant women in drug development. We suggest that the framework consists of using a question based approach with five key questions in combination with three prerequisites which should be addressed when considering inclusion of pregnant women in drug research. The five questions are: A. Can we consider the drug safe (enough) for first exposure in pregnant women and fetuses? B. In which dose range (potentially depending on gestational age) can the drug be considered to remain safe in pregnant women? C. At what dose (regimen, within the range considered safe) can we expect efficacy in pregnant women? D. Can efficacy be confirmed at the target dose, either similar to the initial population or different? E. Can clinical safety be confirmed at a sufficiently acceptable level at the target dose for pregnant women and fetuses, so as to conclude a positive benefit-risk ratio? Combining questions and prerequisites leads to a scheme for appropriate timing of responsible inclusion of pregnant women in drug research. Accordingly, we explore several research design options for including pregnant women in drug trials that are feasible within the framework. Ultimately, the framework may lead to (i) earlier inclusion of pregnant women in drug development, (ii) ensuring that key prerequisites, such as proper dosing, are addressed before more substantial numbers of pregnant women are included in trials, and (iii) optimal use of safety and efficacy data from the initial (nonpregnant) population throughout the drug development process. PMID- 29458399 TI - The effects of Kinesiotape on acute lateral ankle sprain: study protocol for a randomized controlled trial. AB - BACKGROUND: Ankle sprains are some of the most frequent injuries of the musculoskeletal system. However, there is no substantive evidence supporting which treatment strategy is superior. Taping with Kinesiotape (KT) is a new method that is used as an alternative to the more established taping and bracing techniques used for the prophylaxis and treatment of ankle sprains. The aim of this study is to examine the efficacy of KT on ankle sprain by comparing acupuncture combined with KT (AcuKT) with acupuncture alone in patients with acute lateral ankle sprains. METHODS/DESIGN: This study is a prospective, multi center (DongShin University Gwangju Oriental Hospital, DongShin University Mokpo Oriental Hospital, and KyungHee Korean Medicine Hospital), outcome assessor blinded, randomized controlled clinical trial with a 1:1 allocation ratio. Participants (n = 60) with a lateral ankle sprain occurring within 1 week of the study will be randomly assigned to either an acupuncture group (n = 10 at each center (total n = 30)) or an AcuKT group (n = 10 at each center (total n = 30)). The acupuncture group will receive acupuncture treatment at ST36, ST41, BL60, BL62, KI3, KI6, GB39, and GB40 once per day, 5 days per week (excluding Saturday and Sunday) for 1 week. The AcuKT group will receive acupuncture treatment at ST36, ST41, BL60, BL62, KI3, KI6, GB39, and GB40 and the ankle meridian tendino musculature and a figure-of-eight shape form of KT treatment once per day, 5 days per week (excluding Saturday and Sunday) for 1 week. The primary outcome will be pain evaluation assessed according to a Visual Analogue Scale (VAS), while Foot and Ankle Outcome Score (FAOS), edema, European Quality of Life Five Dimension Five Level Scale (EQ-5D-5 L) score, and number of recurrent ankle sprains will be considered as secondary outcome measures. VAS, FAOS, and edema measurements will be performed at baseline (before intervention), 5 days after the first intervention (i.e., at the end of the intervention), and 4 weeks after the completion of intervention. EQ-5D-5 L measurements will be conducted at baseline, 5 days after the first intervention, 4 weeks after the completion of intervention, and 26 weeks after the completion of intervention. The number of recurrent ankle sprains will be determined at 4, 8, 12, and 26 weeks after the completion of the intervention. DISCUSSION: This study will provide data regarding the efficacy of KT for the treatment of acute lateral ankle sprain. The results may lead to insights into the usefulness of KT in the treatment of acute lateral ankle sprain. TRIAL REGISTRATION: cris.nih.go.kr, ID: KCT0002257.

PMID- 29458401 TI - Efficacy and safety of Ding-Kun-Dan for female infertility patients with predicted poor ovarian response undergoing in vitro fertilization/intracytoplasmic sperm injection: study protocol for a randomized controlled trial. AB - BACKGROUND: Women undergoing in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) who have a predicted poor ovarian response (POR) present a challenge for reproductive medicine specialists. Traditional Chinese medicine (TCM) is commonly used in China for such patients, in the belief that it will improve the ovarian response and ultimately increase pregnancy rates. However, there is a lack of high-quality evidence about the effect of TCM on improving ovarian response in such patients. The purpose of this study is to evaluate ongoing viable pregnancy rate at 12 weeks' gestation and related indicators of ovarian response in fertile women who have a predicted poor ovarian response having immediate versus delayed IVF/ICSI after 3 months of Ding-Kun-Dan (DKD) pre treatment. METHODS/DESIGN: This study is a multicenter, randomized controlled, parallel-group, phase III, superiority clinical trial. Two hundred and seventy eight eligible female infertility patients with POR will be included in the study and randomly allocated into an immediate treatment group and a DKD group in a 1:1 ratio. Both groups will receive IVF or ICSI as a standard treatment while in the DKD group, a commercially available Chinese medicine, DKD, will be administrated for 3 months before the IVF/ICSI cycle starts. The primary outcome of the study is the ongoing pregnancy rate at 12 weeks' gestation. The secondary outcomes include total gonadotropin dosage, duration of stimulation, estradiol (E2) and progesterone (P) levels on human chorionic gonadotropin (hCG) trigger day, cycle cancellation rate, number of oocytes retrieved, high-quality embryo rate, biochemical pregnancy rate, the change of serum anti-Mullerian hormone (AMH), follicle-stimulating hormone (FSH), and E2 levels and all side effects, safety outcomes, and any adverse events. The protocol was approved by the Ethics Committee of the First Teaching Hospital of Tianjin university of TCM (approval no. TYLL2017[K] 004). DISCUSSION: IVF/ICSI is increasingly used to treat couples desiring a baby. Many of these women will have poor ovarian function. In China, DKD is commonly used for these patients prior to undergoing IVF/ICSI. There is no effective treatment for poor ovarian response in Western medicine currently. It is important, therefore, to undertake this randomized control trial to determine whether DKD is effective or not. TRIAL REGISTRATION: Chinese Clinical Trial Registry, ID: ChiCTR-IOR-17011697 .

PMID- 29458402 TI - Management of medial humeral epicondyle fractures in children: a structured review protocol for a systematic review of the literature and identification of a core outcome set using a Delphi survey. AB - BACKGROUND: Medial humeral epicondyle fractures of the elbow are one of the most common injuries in childhood and often require surgery. There are currently no standardised outcome measures to assess progress after an elbow injury in a child. Wide variation in currently reported outcomes makes comparison of treatment difficult. This study aims to identify outcome measures that have previously been reported in studies evaluating the management of medial epicondyle fractures in children and to facilitate the development of a consensus core outcome set (COS) suitable for use in all future studies of medial humeral epicondyle fractures in children. METHODS/DESIGN: This study will include a systematic review of the academic literature to identify a list of outcome measures that have previously been reported. The list of outcome measures will be used in a consensus setting exercise with focus groups of key stakeholders to identify key outcomes. A Delphi process to include two rounds will then be used to define the most important outcomes to all stakeholders forming the COS. DISCUSSION: Core outcomes represent the minimum expected data reported for a specific condition and will improve the quality of future studies reducing bias, allowing easier comparison and enhancing opportunities for larger meta-analysis. It is anticipated that this COS will form part of the feasibility to a National Institute for Health Research (NIHR) Health Technology Assessment (HTA)-funded trial concerning the management of elbow fractures in children.

PMID- 29458403 TI - Overuse in cancer care: do European studies provide information useful to support policies? AB - Health services overuse has been acknowledged as a relevant policy issue. In this study, we assessed the informative value of research on the quality of cancer care, exploring to what extent it is actually concerned with care overuse, thus providing policy-makers with sound estimates of overuse prevalence. We searched Medline for European studies, reporting information on the rate of use of diagnostic or therapeutic procedures/interventions in breast, colorectal, lung and prostate cancer patients, published in English between 2006 and 2016. Individual studies were classified with regards to their orientation towards overuse according to the quality metrics adopted in assessing rates of use of procedures and interventions.Out of 1882 papers identified, 100 accounting for 94 studies met our eligibility criteria, most of them on breast (n = 38) and colorectal (n = 30) cancer. Of these, 46 (49%) studies relied on process indicators allowing a direct measure of under- or overuse, the latter being addressed in 22 (24%) studies. Search for overuse in patterns of care did not increase over time, with overuse being measured in 24% of the studies published before 2010, and in only 13% of those published in 2015-2016. Information on its prevalence was available only for a relatively limited number of procedures/interventions. Overall, estimates of overuse tended to be higher for diagnostic procedures (median prevalence across all studies, 24%) than for drugs, surgical procedures or radiotherapy (median overuse prevalence always lower than 10%). Despite its increasing policy relevance, overuse is still an often overlooked issue in current European research on the quality of care for cancer patients. PMID- 29458404 TI - A novel integrated care concept (NICC) versus standard care in the treatment of chronic cardiovascular diseases: protocol for the randomized controlled trial CardioCare MV. AB - BACKGROUND: Cardiovascular diseases are the major cause of death globally and represent a major economic burden on health care systems. Positive effects of disease management programs have been shown for patients with heart failure (HF). Remote monitoring and telemonitoring with active intervention are beneficial in atrial fibrillation (AF) and therapy-resistant hypertension (TRH), respectively. For these patients, we have developed a novel integrated care concept (NICC) which combines telemedicine with intensive support by a care center, including a call center, an integrated care network including inpatient and outpatient care providers and guideline therapy for patients. METHODS: The aim of the study is to demonstrate the superiority of NICC over guideline therapy alone. The trial is designed as open-label, bi-center, parallel-group design with two groups and a blinded observer. Patients will be included if they are either inpatients or if they are referred to the outpatient clinic of the hospitals by their treating physician. Randomization will be done individually with stratification by cardiovascular disease (AF, HF, TRH), center and admission type. Primary endpoints are based on the 1-year observation period after randomization. The first primary endpoint is the composite endpoint consisting of mortality, stroke and myocardial infarction. The number of hospitalizations form the second primary endpoint. The third primary endpoint is identical to the first primary endpoint plus cardiac decompensation. Adjustments for multiple testing are done using a fall-back strategy. Secondary endpoints include patient adherence, health care costs, quality of life, and safety. A sample size of 2930 gives 80% power at the two-sided 2.5% test level for the first primary endpoint. The power for the second primary endpoint is 99.8% at this sample size, and it is 80% with 1086 patients. DISCUSSION: This study will inform care providers whether quality of care can be improved by an integrated care concept providing telemedicine through a round-the-clock call center approach. We expect that cost of the NICC will be lower than standard care because of reduced hospitalizations. If the study has a positive result, NICC is planned to be immediately rolled out in the federal state of Mecklenburg-West Pomerania and other federal states in Germany. The trial will also guide additional research to disentangle the effects of this complex intervention. TRIAL REGISTRATION: DRKS, ID: DRKS00013124 .

PMID- 29458405 TI - Dacomitinib potentiates the efficacy of conventional chemotherapeutic agents via inhibiting the drug efflux function of ABCG2 in vitro and in vivo. AB - BACKGROUND: ATP-binding cassette subfamily G member 2 (ABCG2), a member of the ABC transporter superfamily proteins, mediates multidrug resistance (MDR) by transporting substrate anticancer drugs out of cancer cells and decreasing their intracellular accumulation. MDR is a major hurdle to successful chemotherapy. A logical approach to overcome MDR is to inhibit the transporter. However, no safe and effective MDR inhibitor has been approved in the clinic. METHODS: The MTT assay was used to evaluate cell cytotoxicity and MDR reversal effect. Drug efflux and intracellular drug accumulation were measured by flow cytometry. The H460/MX20 cell xenograft model was established to evaluate the enhancement of anticancer efficacy of topotecan by dacomitinib in vivo. To ascertain the interaction of dacomitinib with the substrate binding sites of ABCG2, the competition of dacomitinib for photolabeling of ABCG2 with [125I]- iodoarylazidoprazosin (IAAP) was performed. Vanadate-sensitive ATPase activity of ABCG2 was measured in the presence of a range of different concentrations of dacomitinib to evaluate the effect of dacomitinib on ATP hydrolysis as the energy source of the transporter. A flow cytometry-based assay and western blotting were employed to study whether dacomitininb could inhibit the expression level of ABCG2. The mRNA expression levels of ABCG2 were analyzed by real-time quantitative RT-PCR. The protein expression level of AKT, ERK and their phosphorylations were detected by Western blotting. RESULTS: Here, we found that dacomitinib, an irreversible pan-ErbB tyrosine kinase inhibitor (TKI) in phase III clinical trial, could enhance the efficacy of conventional chemotherapeutic agents specifically in ABCG2-overexpressing MDR cancer cells but not in the parental sensitive cells. Dacomitinib was found to significantly increase the accumulation of ABCG2 probe substrates [doxorubicin (DOX),Rhodamine 123 (Rho 123) and Hoechst 33342] by inhibiting the transporter efflux function. Moreover, dacomitinib stimulated ABCG2 ATPase activity and competed with [125I]-IAAP photolabeling of ABCG2 in a concentration-dependent manner. However, dacomitinib did not alter ABCG2 expression at protein and mRNA levels or inhibit ErbB downstream signaling of AKT and ERK. Importantly, dacomitinib significantly enhanced the efficacy of topotecan in ABCG2-overexpressing H460/MX20 cell xenografts in nude mice without incurring additional toxicity. CONCLUSIONS: These results suggest that dacomitinib reverses ABCG2-mediated MDR by inhibiting ABCG2 efflux function and increasing intracellular accumulation of anticancer agents. Our findings advocate further clinical investigation of combinations of dacomitinib and conventional chemotherapy in cancer patients with ABCG2 overexpressing MDR tumors. PMID- 29458406 TI - Assessing dengue transmission risk and a vector control intervention using entomological and immunological indices in Thailand: study protocol for a cluster randomized controlled trial. AB - BACKGROUND: Dengue fever is the most common and widespread mosquito-borne arboviral disease in the world. There is a compelling need for cost-effective approaches and practical tools that can reliably measure real-time dengue transmission dynamics that enable more accurate and useful predictions of incidence and outbreaks. Sensitive surveillance tools do not exist today, and only a small handful of new control strategies are available. Vector control remains at the forefront for combating dengue transmission. However, the effectiveness of many current vector control interventions is fraught with inherent weaknesses. No single vector control method is effective enough to control both vector populations and disease transmission. Evaluations of novel larval and adult control interventions are needed. METHODS/DESIGN: A cluster randomized controlled trial will be carried out between 2017 and 2019 in urban community clusters in Khon Kaen and Roi Et cities, northeastern Thailand. The effectiveness of a pyriproxyfen/spinosad combination treatment of permanent water storage containers will be evaluated on epidemiological and entomological outcomes, including dengue incidence, number of female adult dengue vectors infected or not infected with dengue virus (DENV), human exposure to Aedes mosquito bites, and several other indices. These indices will also be used to develop predictive models for dengue transmission and impending outbreaks. Epidemiological and entomological data will be collected continuously for 2 years, with the intervention implemented after 1 year. DISCUSSION: The aims of the trial are to simultaneously evaluate the efficacy of an innovative dengue vector control intervention and developing predictive dengue models. Assessment of human exposure to mosquito bites by detecting antibodies generated against Aedes saliva proteins in human blood samples has, so far, not been applied in dengue epidemiological risk assessment and disease surveillance methodologies. Likewise, DENV detection in mosquitoes (adult and immature stages) has not been used in any practical way for routine disease surveillance strategies. The integration of multiple outcome measures will assist health authorities to better predict outbreaks for planning and applying focal and timely interventions. The trial outcomes will not only be important for Thailand, but also for the entire Southeast Asian region and further afield. TRIAL REGISTRATION: ISRCTN, ISRCTN73606171 . Registered on 23 June 2017. PMID- 29458407 TI - Effectiveness of a transdiagnostic individually tailored Internet-based and mobile-supported intervention for the indicated prevention of depression and anxiety (ICare Prevent) in Dutch college students: study protocol for a randomised controlled trial. AB - BACKGROUND: Depression and anxiety are common and co-morbid disorders that affect a significant proportion of students. Innovative prevention strategies targeting both conditions are needed to reduce their health burden and costs. ICare Prevent is such an innovative strategy and contains a transdiagnostic individually tailored Internet-based and mobile-supported intervention. It addresses common risk factors of depression and anxiety as part of a large EU-funded multi-country project* (ICare). Little is known about the clinical and cost-effectiveness of this type of intervention compared to care as usual (CAU) for college students. We hypothesize that ICare Prevent will be more (cost-)effective than CAU in the reduction of symptoms of depression and anxiety. METHODS: A three-arm, parallel, randomized controlled superiority trial will be conducted comparing a guided and an unguided version of ICare Prevent with a control group receiving CAU. The trial will be open-label but outcome assessors will be blinded. A total of 252 college students (age >= 16 years) with subclinical symptoms of depression defined as a score >= 16 on the Center for Epidemiological Studies Depression Scale (CES-D), and/or anxiety, defined as a score >= 5 on the Generalized Anxiety Disorder scale (GAD-7), will be included. Those meeting diagnostic criteria for a depressive or anxiety disorder will be excluded. The primary outcome is change in disorder specific symptom severity from baseline to post-intervention. Secondary endpoints include self-reported depression and anxiety symptoms as well as time to onset of a mood or anxiety disorder until 12-month follow-up. Societal costs and quality of life will be assessed to estimate the intervention's cost effectiveness compared to CAU. DISCUSSION: Transdiagnostic individually tailored Internet-based prevention could be a (cost-)effective approach to tackle the disease burden of depression and anxiety among college students. TRIAL REGISTRATION: Dutch trial register, NTR 6562 . Registered on 6 July 2017. PMID- 29458408 TI - Catheter Ablation versus Thoracoscopic Surgical Ablation in Long Standing Persistent Atrial Fibrillation (CASA-AF): study protocol for a randomised controlled trial. AB - BACKGROUND: Atrial fibrillation is the commonest arrhythmia which raises the risk of heart failure, thromboembolic stroke, morbidity and death. Pharmacological treatments of this condition are focused on heart rate control, rhythm control and reduction in risk of stroke. Selective ablation of cardiac tissues resulting in isolation of areas causing atrial fibrillation is another treatment strategy which can be delivered by two minimally invasive interventions: percutaneous catheter ablation and thoracoscopic surgical ablation. The main purpose of this trial is to compare the effectiveness and safety of these two interventions. METHODS/DESIGN: Catheter Ablation versus Thoracoscopic Surgical Ablation in Long Standing Persistent Atrial Fibrillation (CASA-AF) is a prospective, multi-centre, randomised controlled trial within three NHS tertiary cardiovascular centres specialising in treatment of atrial fibrillation. Eligible adults (n = 120) with symptomatic, long-standing, persistent atrial fibrillation will be randomly allocated to either catheter ablation or thoracoscopic ablation in a 1:1 ratio. Pre-determined lesion sets will be delivered in each treatment arm with confirmation of appropriate conduction block. All patients will have an implantable loop recorder (ILR) inserted subcutaneously immediately following ablation to enable continuous heart rhythm monitoring for at least 12 months. The devices will be programmed to detect episodes of atrial fibrillation and atrial tachycardia >= 30 s in duration. The patients will be followed for 12 months, completing appropriate clinical assessments and questionnaires every 3 months. The ILR data will be wirelessly transmitted daily and evaluated every month for the duration of the follow-up. The primary endpoint in the study is freedom from atrial fibrillation and atrial tachycardia at the end of the follow-up period. DISCUSSION: The CASA-AF Trial is a National Institute for Health Research-funded study that will provide first-class evidence on the comparative efficacy, safety and cost-effectiveness of thoracoscopic surgical ablation and conventional percutaneous catheter ablation for long-standing persistent atrial fibrillation. In addition, the results of the trial will provide information on the effects on patients' quality of life. TRIAL REGISTRATION: ISRCTN Registry, ISRCTN18250790 . Registered on 24 April 2015. PMID- 29458409 TI - Mitochondrial dysfunction and autism: comprehensive genetic analyses of children with autism and mtDNA deletion. AB - BACKGROUND: The etiology of autism spectrum disorders (ASD) is very heterogeneous. Mitochondrial dysfunction has been described in ASD; however, primary mitochondrial disease has been genetically proven in a small subset of patients. The main goal of the present study was to investigate correlations between mitochondrial DNA (mtDNA) changes and alterations of genes associated with mtDNA maintenance or ASD. METHODS: Sixty patients with ASD and sixty healthy individuals were screened for common mtDNA mutations. Next generation sequencing was performed on patients with major mtDNA deletions (mtdel-ASD) using two gene panels to investigate nuclear genes that are associated with ASD or are responsible for mtDNA maintenance. Cohorts of healthy controls, ASD patients without mtDNA alterations, and patients with mitochondrial disorders (non-ASD) harbouring mtDNA deletions served as comparison groups. RESULTS: MtDNA deletions were confirmed in 16.6% (10/60) of patients with ASD (mtdel-ASD). In 90% of this mtdel-ASD children we found rare SNVs in ASD-associated genes (one of those was pathogenic). In the intergenomic panel of this cohort one likely pathogenic variant was present. In patients with mitochondrial disease in genes responsible for mtDNA maintenance pathogenic mutations and variants of uncertain significance (VUS) were detected more frequently than those found in patients from the mtdel ASD or other comparison groups. In healthy controls and in patients without a mtDNA deletion, only VUS were detected in both panel. CONCLUSIONS: MtDNA alterations are more common in patients with ASD than in control individuals. MtDNA deletions are not isolated genetic alterations found in ASD; they coexist either with other ASD-associated genetic risk factors or with alterations in genes responsible for intergenomic communication. These findings indicate that mitochondrial dysfunction is not rare in ASD. The occurring mtDNA deletions in ASD may be mostly a consequence of the alterations of the causative culprit genes for autism or genes responsible for mtDNA maintenance, or because of the harmful effect of environmental factors. PMID- 29458410 TI - Human regulatory proteins associate with non-coding RNAs from the EBV IR1 region. AB - OBJECTIVE: The function of Epstein-Barr virus (EBV) stable intronic sequence (sis)RNAs, non-coding RNAs transcribed from a region required for EBV-mediated cellular transformation, remain unknown. To better understand the function of ebv sisRNA-1 and ebv-sisRNA-2 from the internal repeat (IR)1 region of EBV, we used a combination of bioinformatics and biochemistry to identify associated RNA binding proteins. The findings reported here are part of ongoing studies to determine the functions of non-coding RNAs from the IR1 region of EBV. RESULTS: Human regulatory proteins HNRNPA1 (heterogeneous nuclear ribonucleoprotein A1), HNRNPC, HNRNPL, HuR (human antigen R), and protein LIN28A (lin-28 homolog A) were predicted to bind ebv-sisRNA-1 and/or ebv-sisRNA-2; FUS (fused in sarcoma) was predicted to associate with ebv-sisRNA-2. Protein interactions were validated using a combination of RNA immunoprecipitation and biotin pulldown assays. Both sisRNAs also precipitated with HNRNPD and NONO (non-POU domain-containing octamer binding protein). Interestingly, each of these interacting proteins also precipitated non-spliced non-coding RNA sequences transcribed from the IR1 region. Our findings suggest interesting roles for sisRNAs (through their interactions with regulatory proteins) and provide further evidence for the existence of non-spliced stable non-coding RNAs. PMID- 29458411 TI - Genome-wide pleiotropy analysis of neuropathological traits related to Alzheimer's disease. AB - BACKGROUND: Simultaneous consideration of two neuropathological traits related to Alzheimer's disease (AD) has not been attempted in a genome-wide association study. METHODS: We conducted genome-wide pleiotropy analyses using association summary statistics from the Beecham et al. study (PLoS Genet 10:e1004606, 2014) for AD-related neuropathological traits, including neuritic plaque (NP), neurofibrillary tangle (NFT), and cerebral amyloid angiopathy (CAA). Significant findings were further examined by expression quantitative trait locus and differentially expressed gene analyses in AD vs. control brains using gene expression data. RESULTS: Genome-wide significant pleiotropic associations were observed for the joint model of NP and NFT (NP + NFT) with the single-nucleotide polymorphism (SNP) rs34487851 upstream of C2orf40 (alias ECRG4, P = 2.4 * 10-8) and for the joint model of NFT and CAA (NFT + CAA) with the HDAC9 SNP rs79524815 (P = 1.1 * 10-8). Gene-based testing revealed study-wide significant associations (P <= 2.0 * 10-6) for the NFT + CAA outcome with adjacent genes TRAPPC12, TRAPPC12-AS1, and ADI1. Risk alleles of proxy SNPs for rs79524815 were associated with significantly lower expression of HDAC9 in the brain (P = 3.0 * 10-3), and HDAC9 was significantly downregulated in subjects with AD compared with control subjects in the prefrontal (P = 7.9 * 10-3) and visual (P = 5.6 * 10-4) cortices. CONCLUSIONS: Our findings suggest that pleiotropy analysis is a useful approach to identifying novel genetic associations with complex diseases and their endophenotypes. Functional studies are needed to determine whether ECRG4 or HDAC9 is plausible as a therapeutic target. PMID- 29458412 TI - Comparison of volatile anesthetic-induced preconditioning in cardiac and cerebral system: molecular mechanisms and clinical aspects. AB - Volatile anesthetic-induced preconditioning (APC) has shown to have cardiac and cerebral protective properties in both pre-clinical models and clinical trials. Interestingly, accumulating evidences demonstrate that, except from some specific characters, the underlying molecular mechanisms of APC-induced protective effects in myocytes and neurons are very similar; they share several major intracellular signaling pathways, including mediating mitochondrial function, release of inflammatory cytokines and cell apoptosis. Among all the experimental results, cortical spreading depolarization is a relative newly discovered cellular mechanism of APC, which, however, just exists in central nervous system. Applying volatile anesthetic preconditioning to clinical practice seems to be a promising cardio-and neuroprotective strategy. In this review, we also summarized and discussed the results of recent clinical research of APC. Despite all the positive experimental evidences, large-scale, long-term, more precisely controlled clinical trials focusing on the perioperative use of volatile anesthetics for organ protection are still needed. PMID- 29458413 TI - Gut microbiota trajectory in early life may predict development of celiac disease. AB - BACKGROUND: To investigate whether alterations in the developing intestinal microbiota and immune markers precede celiac disease (CD) onset in infants at familial risk of developing the disease. METHODS: A nested case-control study was carried out as part of a larger prospective cohort study, which included healthy full-term newborns (> 200) with at least one first relative with biopsy-verified CD. The present study includes cases of CD (n = 10) and the best-matched controls (n = 10) who did not develop the disease after 5-year follow-up. Fecal microbiota, assessed by high-throughput 16S rRNA gene amplicon sequencing, and immune parameters were profiled at 4 and 6 months of age and related to CD onset. RESULTS: The microbiota of infants who remained healthy showed an increase in bacterial diversity over time, characterized by increases in Firmicutes families, but not those who developed CD. Infants who subsequently developed CD showed a significant reduction in sIgA levels over time, while those who remained healthy showed increases in TNF-alpha correlated to Bifidobacterium spp. An increased relative abundance of Bifidobacterium longum was associated with control children while increased proportions of Bifidobacterium breve and Enterococcus spp. were associated with CD development. CONCLUSION: The findings suggest that alterations in the early trajectory of gut microbiota in infants at CD risk could influence the immune maturation process and predispose to CD, although larger population studies are warranted to confirm this hypothesis. PMID- 29458414 TI - Bilateral internal jugular vein thrombosis due to malignant tumor. AB - BACKGROUND: The aim of the study was to analyze characteristics of patients with bilateral internal jugular vein thrombosis in our department during a 1-year period. Internal jugular vein thrombosis refers to an intraluminal thrombus occurring anywhere from the intracranial internal jugular vein to the junction of the internal jugular vein and the subclavian vein, which form the brachiocephalic vein. It can occur spontaneously or as a complication of head and neck infections, surgery, central venous lines, local malignancy, polycytemia, hyperhomocysteinemia, neck massage, or intravenous drug abuse. Spontaneous bilateral internal jugular vein thrombosis may occur as a result of a neoplasm, a condition called Trousseau's syndrome. METHODS: The medical records of four patients with internal jugular vein thrombosis were reviewed for patient clinical characteristics, including age, sex, and other diseases. This is a retrospective study, and we analyzed four patients who had distant malignant tumors. RESULTS: During a 1-year period, four male patients were referred to our department for bilateral internal jugular vein thrombosis. Three of them had lung neoplasm, and one had urinary tract neoplasm. Three patients had thrombosis in the upper arm at the same time, one of them in both arms. Therapy consisted of unfractioned heparin in all patients. The main clinical manifestations were pain and cervical edema. The time between the first clinical manifestation and diagnosis of internal jugular vein thrombosis was 4 days. In the current study, no patient exhibited complications due to internal jugular vein thrombosis. CONCLUSIONS: Diagnosing internal jugular vein thrombosis requires a high degree of suspicion. Our study underlines that bilateral internal jugular vein thrombosis is a risk indicator for malignancy. In our literature review of internal jugular vein thrombosis, 85% of patients exhibited unilateral thrombosis, whereas the remaining patients had bilateral thrombosis (15%). The knowledge of predictive factors of internal jugular vein thrombosis seems to be of utmost importance to improve patient management. PMID- 29458415 TI - A protocol for a systematic review of non-randomised evaluations of strategies to increase participant retention to randomised controlled trials. AB - BACKGROUND: Randomised control trials are regarded as the gold standard for evaluating the effectiveness and efficacy of healthcare interventions with thousands of trials published every year. Despite significant investment in infrastructure, a staggering number of clinical trials continue to face challenges with retention. Dropouts could lead to negative consequences-from lengthy delays to missing data that can undermine the results and integrity of the trial. Summarising evidence from non-randomised evaluations of retention strategies could provide complementary information to randomised evaluations that could guide trialists to the most effective ways of increasing retention of participants in clinical trials. METHODS: The following electronic databases will be searched for relevant studies: EMBASE, MEDLINE, the Cochrane Controlled Trials Register, and Cochrane Methodology Register and the search will be limited to English-published studies during the last 10 years to increase relevance to current trials. Non-randomised studies (observational studies) including a comparison of two or more strategies to increase participant retention in randomised trials or comparing one or more strategies with no strategy will be included. The primary outcome will be the proportion of participants remained at the primary analysis as determined in each retention study. DISCUSSION: This review aims to gather and evaluate evidence on the effect of retention strategies examined in non-randomised studies. It is imperative to collect evidence from obseravational studies to infer whether or not these studies could be considered a practical way to complement or even replace a broadly favourable randomised design. If we find that non-randomised studies to be included in this review are of high quality with adequate control of biases, we will recommend to trialists and others not to rely exclusively on randomised studies and to give meticulous attention to the plentiful evidence that can be obtained from non-randomised studies. Should the results of this review suggest that evaluating retention strategies in observational studies provides insufficient evidence to trialists planning their retention strategies, we will be able to say that there is little point in conducting non-randomised studies and that they would do better to invest their time and resources in a randomised evaluation if possible. Where a non-randomised study design is chosen, the review authors will offer recommendations to trialists and others regarding how to ensure that these studies are conducted in a way that can minimise the risk of bias and increase confidence in the findings.

PMID- 29458416 TI - Cholera diagnosis in human stool and detection in water: protocol for a systematic review of available technologies. AB - BACKGROUND: Cholera is a highly infectious diarrheal disease spread via fecal contamination of water and food sources; it is endemic in parts of Africa and Asia and recent outbreaks have been reported in Haiti, the Zambia and Democratic Republic of the Congo. If left untreated, the disease can be fatal in less than 24 h and result in case fatality ratios of 30-50%. Cholera disproportionately affects those living in areas with poor access to water and sanitation: the long term public health response is focused on improving water and hygiene facilities and access. Short-term measures for infection prevention and control, and disease characterization and surveillance, are impaired by diagnostic delays: culture methods are slow and rely on the availability of infrastructure and specialist equipment. Rapid diagnostic tests have shown promise under field conditions and further innovations in this area have been proposed. METHODS: This paper is the protocol for a systematic review focused on identifying current technologies and methods used for cholera diagnosis in stool, and detection in water. We will synthesize and appraise information on product technical specifications, accuracy and design features in order to inform infection prevention and control and innovation development. Embase, MEDLINE, CINAHL, Proquest, IndMed and the WHO and Campbell libraries will be searched. We will include studies reporting on field evaluations, including within-study comparisons against a reference standard, and laboratory evaluations reporting on product validation against field stool or water samples. We will extract data according to protocol and attempt meta analyses if appropriate given data availability and quality. DISCUSSION: The systematic review builds on a previous scoping review in this field and expands upon this by synthesising data on both product technical characteristics and design features. The review will be of particular value to stakeholders engaged in diagnostic procurement and manufacturers interested in developing cholera or diarrheal disease diagnostics. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42016048428 . PMID- 29458417 TI - Cooperative p16 and p21 action protects female astrocytes from transformation. AB - Mechanisms underlying sex differences in cancer incidence are not defined but likely involve dimorphism (s) in tumor suppressor function at the cellular and organismal levels. As an example, sexual dimorphism in retinoblastoma protein (Rb) activity was shown to block transformation of female, but not male, murine astrocytes in which neurofibromin and p53 function was abrogated (GBM astrocytes). Correlated sex differences in gene expression in the murine GBM astrocytes were found to be highly concordant with sex differences in gene expression in male and female GBM patients, including in the expression of components of the Rb and p53 pathways. To define the basis of this phenomenon, we examined the functions of the cyclin dependent kinase (CDK) inhibitors, p16, p21 and p27 in murine GBM astrocytes under conditions that promote Rb-dependent growth arrest. We found that upon serum deprivation or etoposide-induced DNA damage, female, but not male GBM astrocytes, respond with increased p16 and p21 activity, and cell cycle arrest. In contrast, male GBM astrocytes continue to proliferate, accumulate chromosomal aberrations, exhibit enhanced clonogenic cell activity and in vivo tumorigenesis; all manifestations of broad sex differences in cell cycle regulation and DNA repair. Differences in tumorigenesis disappeared when female GBM astrocytes are also rendered null for p16 and p21. These data elucidate mechanisms underlying sex differences in cancer incidence and demonstrate sex-specific effects of cytotoxic and targeted therapeutics. This has critical implications for lab and clinical research. PMID- 29458418 TI - Amyloid beta-induced impairments on mitochondrial dynamics, hippocampal neurogenesis, and memory are restored by phosphodiesterase 7 inhibition. AB - BACKGROUND: The phosphodiesterase (PDE) 7 inhibitor S14 is a cell-permeable small heterocyclic molecule that is able to cross the blood-brain barrier. We previously found that intraperitoneal treatment with S14 exerted neuroprotection in an Alzheimer's disease (AD) model (in APP/PS1 mice). The objective of this study was to investigate the neurogenic and cellular effects of oral administration of S14 on amyloid beta (Abeta) overload. METHODS: We orally administered the PDE7 inhibitor S14 (15 mg/kg/day) or vehicle in 6-month-old APP/PS1 mice. After 5 weeks of S14 treatment, we evaluated cognitive functions and brain tissues. We also assessed the effects of S14 on the Abeta-treated human neuroblastome SH-SY5Y cell line. RESULTS: Targeting the cyclic adenosine monophosphate (cAMP)/cAMP-response element binding protein (CREB) pathway, S14 rescued cognitive decline by improving hippocampal neurogenesis in APP/PS1 transgenic mice. Additionally, S14 treatment reverted the Abeta-induced reduction in mitochondrial mass in APP/PS1 mice and in the human neuroblastoma SH-SY5Y cells co-exposed to Abeta. The restoration of the mitochondrial mass was found to be a dual effect of S14: a rescue of the mitochondrial biogenesis formerly slowed down by Abeta overload, and a reduction in the Abeta-increased mitochondrial clearance mechanism of mitophagy. CONCLUSIONS: Here, we show new therapeutic effects of the PDE7 inhibitor, confirming S14 as a potential therapeutic drug for AD. PMID- 29458419 TI - Insights about genome function from spatial organization of the genome. AB - Over the last 15 years, development of chromosome conformation capture (3C) and its subsequent high-throughput variants in conjunction with the fast development of sequencing technology has allowed investigators to generate large volumes of data giving insights into the spatial three-dimensional (3D) architecture of the genome. This huge data has been analyzed and validated using various statistical, mathematical, genomics, and biophysical tools in order to examine the chromosomal interaction patterns, understand the organization of the chromosome, and find out functional implications of the interactions. This review summarizes the data generated by several large-scale high-throughput chromosome conformation capture studies and the functional implications obtained from the data analyses. We also discuss emerging results on factors (both CCCTC binding factor (CTCF) related and CTCF independent) that could contribute to looping interactions. PMID- 29458420 TI - Effects of pharmacological and nonpharmacological treatments on brain functional magnetic resonance imaging in Alzheimer's disease and mild cognitive impairment: a critical review. AB - BACKGROUND: A growing number of pharmacological and nonpharmacological trials have been performed to test the efficacy of approved or experimental treatments in Alzheimer disease (AD) and mild cognitive impairment (MCI). In this context, functional magnetic resonance imaging (fMRI) may be a good candidate to detect brain changes after a short period of treatment. MAIN BODY: This critical review aimed to identify and discuss the available studies that have tested the efficacy of pharmacological and nonpharmacological treatments in AD and MCI cases using task-based or resting-state fMRI measures as primary outcomes. A PubMed-based literature search was performed with the use of the three macro-areas: 'disease', 'type of MRI', and 'type of treatment'. Each contribution was individually reviewed according to the Cochrane Collaboration's tool for assessing risk of bias. Study limitations were systematically detected and critically discussed. We selected 34 pharmacological and 13 nonpharmacological articles. According to the Cochrane Collaboration's tool for assessing risk of bias, 40% of these studies were randomized but only a few described clearly the randomization procedure, 36% declared the blindness of participants and personnel, and only 21% reported the blindness of outcome assessment. In addition, 28% of the studies presented more than 20% drop-outs at short- and/or long-term assessments. Additional common shortcomings of the reviewed works were related to study design, patient selection, sample size, choice of outcome measures, management of drop-out cases, and fMRI methods. CONCLUSION: There is an urgent need to obtain efficient treatments for AD and MCI. fMRI is powerful enough to detect even subtle changes over a short period of treatment; however, the soundness of methods should be improved to enable meaningful data interpretation. PMID- 29458421 TI - Epidemiology of canine gastrointestinal helminths in sub-Saharan Africa. AB - BACKGROUND: Dogs have a close association with humans providing companionship, security and a source of dietary protein. However, dogs are also potential carriers of zoonotic pathogens. Dogs, therefore, pose a public health risk and a good understanding of canine diseases is important for planning and implementing control measures. The aim of this study was to characterise canine helminthiasis in sub-Saharan Africa using a systematic approach. METHODS: Pubmed and Google Scholar were searched for relevant primary studies published from 2000. Forty-one eligible studies were included in the meta-analysis. Pooled prevalences were estimated using the quality effects model. RESULTS AND CONCLUSIONS: Twenty-six genera of enteric helminths were reported and the pooled estimate of canine helminthiasis was 71% (95% CI: 63-79%). Species of Ancylostoma and Toxocara, causative agents of larva migrans in humans, were the most frequently reported helminths with pooled estimated prevalences of 41% (95% CI: 32-50%) and 22% (95% CI: 16-29%), respectively. Dipylidium caninum and Taenia spp. were the most frequently reported cestodes with pooled estimated prevalences of 20% (95% CI: 12 29%) and 9% (95% CI: 5-15%), respectively. Trematodes were rarely reported. There was a high level of heterogeneity in most pooled estimates (I2 ? 80%). The results of this study show that canine helminthiasis is highly prevalent in sub Saharan Africa and there is need for regular deworming programmes to improve the health status of the dogs and minimise the potential health risk to humans. PMID- 29458422 TI - The antibiotic resistome and microbiota landscape of refugees from Syria, Iraq and Afghanistan in Germany. AB - BACKGROUND: Multidrug-resistant bacteria represent a substantial global burden for human health, potentially fuelled by migration waves: in 2015, 476,649 refugees applied for asylum in Germany mostly as a result of the Syrian crisis. In Arabic countries, multiresistant bacteria cause significant problems for healthcare systems. Currently, no data exist describing antibiotic resistances in healthy refugees. Here, we assess the microbial landscape and presence of antibiotic resistance genes (ARGs) in refugees and German controls. To achieve this, a systematic study was conducted in 500 consecutive refugees, mainly from Syria, Iraq, and Afghanistan and 100 German controls. Stool samples were subjected to PCR-based quantification of 42 most relevant ARGs, 16S ribosomal RNA gene sequencing-based microbiota analysis, and culture-based validation of multidrug-resistant microorganisms. RESULTS: The fecal microbiota of refugees is substantially different from that of resident Germans. Three categories of resistance profiles were found: (i) ARGs independent of geographic origin of individuals comprising BIL/LAT/CMA, ErmB, and mefE; (ii) vanB with a high prevalence in Germany; and (iii) ARGs showing substantially increased prevalences in refugees comprising CTX-M group 1, SHV, vanC1, OXA-1, and QnrB. The majority of refugees carried five or more ARGs while the majority of German controls carried three or less ARGs, although the observed ARGs occurred independent of signatures of potential pathogens. CONCLUSIONS: Our results, for the first time, assess antibiotic resistance genes in refugees and demonstrate a substantially increased prevalence for most resistances compared to German controls. The antibiotic resistome in refugees may thus require particular attention in the healthcare system of host countries. PMID- 29458423 TI - The effectiveness of the Inspiring Futures parenting programme in improving behavioural and emotional outcomes in primary school children with behavioural or emotional difficulties: study protocol for a randomised controlled trial. AB - BACKGROUND: There is a need to build the evidence base of early interventions promoting children's health and development in the UK. Malachi Specialist Family Support Services ('Malachi') is a voluntary sector organisation based in the UK that delivers a therapeutic parenting group programme called Inspiring Futures to parents of children identified as having behavioural and emotional difficulties. The programme comprises two parts, delivered sequentially: (1) a group-based programme for all parents for 10-12 weeks, and (2) one-to-one sessions with selected parents from the group-based element for up to 12 weeks. METHODS/DESIGN: A randomised controlled trial will be conducted to evaluate Malachi's Inspiring Futures parenting programme. Participants will be allocated to one of two possible arms, with follow-up measures at 16 weeks (post-parent group programme) and at 32 weeks (post-one-to-one sessions with selected parents). The sample size is 248 participants with a randomisation allocation ratio of 1:1. The intervention arm will be offered the Inspiring Futures programme. The control group will receive services as usual. The aim is to determine the effectiveness of the Inspiring Futures programme on the primary outcome of behavioural and emotional difficulties of primary school children identified as having behavioural or emotional difficulties. DISCUSSION: This study will further enhance the evidence for early intervention parenting programmes for child behavioural and emotional problems in the UK. TRIAL REGISTRATION: Current Controlled Trials ISRCTN32083735 . Retrospectively registered 28 October 2014. PMID- 29458424 TI - Familial human prion diseases associated with prion protein mutations Y226X and G131V are transmissible to transgenic mice expressing human prion protein. AB - Human familial prion diseases are associated with mutations at 34 different prion protein (PrP) amino acid residues. However, it is unclear whether infectious prions are found in all cases. Mutant PrP itself may be neurotoxic, or alternatively, PrP mutation might predispose to spontaneous formation of infectious PrP isoforms. Previous reports demonstrated transmission to animal models by human brain tissue expressing 7 different PrP mutations, but 3 other mutations were not transmissible. In the present work, we tested transmission using brain homogenates from patients expressing 3 untested PrP mutants: G131V, Y226X, and Q227X. Human brain homogenates were injected intracerebrally into tg66 transgenic mice overexpressing human PrP. Mice were followed for nearly 800 days.From 593 to 762 dpi, 4 of 8 mice injected with Y226X brain had PrPSc detectable in brain by immunostaining, immunoblot, and PrP amyloid seeding activity assayed by RT-QuIC. From 531 to 784 dpi, 11 of 11 G131V-injected mice had PrPSc deposition in brain, but none were positive by immunoblot or RT-QuIC assay. In contrast, from 529 to 798 dpi, no tg66 mice injected with Q227X brain had PrPSc or PrP amyloid seeding activity detectable by these methods. Y226X is the only one of 4 known PrP truncations associated with familial disease which has been shown to be transmissible. This transmission of prion infectivity from a patient expressing truncated human PrP may have implications for the spread and possible transmission of other aggregated truncated proteins in prion-like diseases such as Alzheimer's disease, Parkinson's disease and tauopathies. PMID- 29458425 TI - Diffuse microvascular C5b-9 deposition is a common feature in muscle and nerve biopsies from diabetic patients. AB - Terminal complement complex deposition in endomysial capillaries detected by a C5b-9 immunostain is considered a diagnostic feature for dermatomyositis. However, we found widespread microvascular C5b-9 reactivity in a substantial subset of muscle biopsies with denervation changes, and in nerve biopsies of peripheral neuropathies, particularly in patients with diabetes. It is unclear whether the presence of C5b-9 deposition signifies active immune-mediated vascular injury that requires immune suppression therapy. We retrospectively identified 63 nerve biopsies in patients with a documented history of diabetes, 26 of which had concomitant muscle biopsies, as well as 54 control nerve biopsies in patients without a documented diabetes history, 18 of which had concomitant muscle biopsies. C5b-9 immunostain was performed on all cases. 87% of the nerve biopsies and 92% of the muscle biopsies from diabetic patients showed microvascular C5b-9 reactivity, compared to 34% and 50% in non-diabetic patients. The differences were statistically significant (p < 0.0001 for nerve and p = 0.002 for muscle). The C5b-9 reactivity was generally proportional to the extent of microvascular sclerosis in diabetic patients, but unrelated to inflammation or vasculitis. C5b-9 deposition in micro-vasculature in both muscle and nerve is therefore a common feature in patients with diabetic neuropathies and may have diagnostic utility. Precaution needs to be taken before using muscle capillary C5b-9 reactivity as evidence of myositis. PMID- 29458426 TI - Disease-related determinants are associated with mortality in dementia due to Alzheimer's disease. AB - BACKGROUND: Survival after dementia diagnosis varies considerably. Previous studies were focused mainly on factors related to demographics and comorbidity rather than on Alzheimer's disease (AD)-related determinants. We set out to answer the question whether markers with proven diagnostic value also have prognostic value. We aimed to identify disease-related determinants associated with mortality in patients with AD. METHODS: We included 616 patients (50% female; age 67 +/- 8 years; mean Mini Mental State Examination score 22 +/- 3) with dementia due to AD from the Amsterdam Dementia Cohort. Information on mortality was obtained from the Dutch Municipal Register. We used age- and sex adjusted Cox proportional hazards analysis to study associations of baseline demographics, comorbidity, neuropsychology, magnetic resonance imaging (MRI) (medial temporal lobe, global cortical and parietal atrophy, and measures of small vessel disease), and cerebrospinal fluid (CSF) (beta-amyloid 1-42, total tau, and tau phosphorylated at threonine 181 [p-tau]) with mortality (outcome). In addition, we built a multivariate model using forward selection. RESULTS: After an average of 4.9 +/- 2.0 years, 213 (35%) patients had died. Age- and sex adjusted Cox models showed that older age (HR 1.29 [95% CI 1.12-1.48]), male sex (HR 1.60 [95% CI 1.22-2.11]), worse scores on cognitive functioning (HR 1.14 [95% CI 1.01-1.30] to 1.31 [95% CI 1.13-1.52]), and more global and hippocampal atrophy on MRI (HR 1.18 [95% CI 1.01-1.37] and HR 1.18 [95% CI 1.02-1.37]) were associated with increased risk of mortality. There were no associations with comorbidity, level of activities of daily living, apolipoprotein E (APOE) epsilon4 status, or duration of disease. Using forward selection, the multivariate model included a panel of age, sex, cognitive tests, atrophy of the medial temporal lobe, and CSF p-tau. CONCLUSIONS: In this relatively young sample of patients with AD, disease-related determinants were associated with an increased risk of mortality, whereas neither comorbidity nor APOE genotype had any prognostic value. PMID- 29458427 TI - The genomic underpinnings of eukaryotic virus taxonomy: creating a sequence-based framework for family-level virus classification. AB - BACKGROUND: The International Committee on Taxonomy of Viruses (ICTV) classifies viruses into families, genera and species and provides a regulated system for their nomenclature that is universally used in virus descriptions. Virus taxonomic assignments have traditionally been based upon virus phenotypic properties such as host range, virion morphology and replication mechanisms, particularly at family level. However, gene sequence comparisons provide a clearer guide to their evolutionary relationships and provide the only information that may guide the incorporation of viruses detected in environmental (metagenomic) studies that lack any phenotypic data. RESULTS: The current study sought to determine whether the existing virus taxonomy could be reproduced by examination of genetic relationships through the extraction of protein-coding gene signatures and genome organisational features. We found large-scale consistency between genetic relationships and taxonomic assignments for viruses of all genome configurations and genome sizes. The analysis pipeline that we have called 'Genome Relationships Applied to Virus Taxonomy' (GRAViTy) was highly effective at reproducing the current assignments of viruses at family level as well as inter-family groupings into orders. Its ability to correctly differentiate assigned viruses from unassigned viruses, and classify them into the correct taxonomic group, was evaluated by threefold cross-validation technique. This predicted family membership of eukaryotic viruses with close to 100% accuracy and specificity potentially enabling the algorithm to predict assignments for the vast corpus of metagenomic sequences consistently with ICTV taxonomy rules. In an evaluation run of GRAViTy, over one half (460/921) of (near)-complete genome sequences from several large published metagenomic eukaryotic virus datasets were assigned to 127 novel family-level groupings. If corroborated by other analysis methods, these would potentially more than double the number of eukaryotic virus families in the ICTV taxonomy. CONCLUSIONS: A rapid and objective means to explore metagenomic viral diversity and make informed recommendations for their assignments at each taxonomic layer is essential. GRAViTy provides one means to make rule-based assignments at family and order levels in a manner that preserves the integrity and underlying organisational principles of the current ICTV taxonomy framework. Such methods are increasingly required as the vast virosphere is explored. PMID- 29458428 TI - A review of promoting access to medicines in China - problems and recommendations. AB - BACKGROUND: Despite recent reforms, distorting funding mechanisms and over prescribing still maintain severe financial barriers to medicines access in China. Complicated and interrelated problems in the pharmaceutical sector require a common framework to be resolved as fragmented solutions do not work. We present a preliminary assessment of the impact of the national healthcare reforms on access to medicines, and propose policy recommendations for promoting universal access to medicines in China. METHODS: Drawing on multiple sources of information, including a review of published literatures and official national data, field investigations in six provinces and interviews with key opinion leaders, this paper presents a preliminary assessment of the impact of the national healthcare reforms on access to medicines, and proposes policy recommendations for promoting universal access to medicines in China. RESULTS: Public expenditure on medicines has been strictly controlled since the national healthcare reforms of 2009. Yet total pharmaceutical expenditure (TPE) and total health expenditure growth rates continuously outpaced the growth of gross domestic product (GDP). With 2.4% of GDP, TPE now exceeds that of most high income countries. The distorted provider and consumer incentives in the Chinese health system have not fundamentally changed. Price-setting and reimbursement mechanisms do not promote cost-effective use of medicines. Inappropriate price controls and perverse financial incentives are the un-resolved root causes of preference of originator brands for some major diseases and shortages of low-cost and low-consumption medicines. In addition, access to expensive life-saving medicines is yet systematically addressed. CONCLUSIONS: The complicated and interdependent problems interact in a way that leads to significant system problems in China, which create dual challenges that both the developing country and the developed countries are facing. To further promote access to medicines, China should speed up the re-assessment of the quality and efficacy of domestically produced generic medicines; coordinate various reforms of price determination, insurance payments, and procurement policies; address medicine shortages through comprehensive policies and legislation; establish specific mechanisms to achieve sustainable equitable access to expensive essential medicines with health technology assessment as a tool to ensure that policy and priority setting are created in a coherent and evidence-based way.

AB - BACKGROUND: The proposal of the new criteria for the diagnosis of Alzheimer's disease (AD) based on biomarker data is making possible a diagnosis of AD at the mild cognitive impairment (MCI) or predementia/prodromal- stage. Given the present lack of effective treatments for AD, the opportunity for the individuals to personally take relevant decisions and plan for their future before and if cognitive deterioration occurs is one the main advantages of an early diagnosis. MAIN BODY: Advance directives are largely seen as an effective tool for planning medical care in the event the subject becomes incompetent. Nevertheless, their value has been questioned with regard to people with dementia by scholars who refer to the arguments of personal identity and of patient's changing interests before and after the onset of dementia. In this paper, I discuss the value of advance directives in Alzheimer's disease and other kind of dementia. Despite critics, I argue that advance directives are especially advisable in dementia and provide reasons in favor of their promotion at an early stage of the disease as a valuable tool to respect patients' values and preferences on medical treatment, including participation in research and end of life decisions. I mainly support advance directives that include both decisions regarding health care and the appointment of an attorney in fact. CONCLUSION: I conclude that patients with AD at a prodromal or early stage should be offered the opportunity to execute an advance directive, and that not to honor a demented individual's directive would be an unacceptable form of discrimination towards those patients. PMID- 29458430 TI - Comparison of fast multi-slice and standard segmented techniques for detection of late gadolinium enhancement in ischemic and non-ischemic cardiomyopathy - a prospective clinical cardiovascular magnetic resonance trial. AB - BACKGROUND: Segmented phase-sensitive inversion recovery (PSIR) cardiovascular magnetic resonance (CMR) sequences are reference standard for non-invasive evaluation of myocardial fibrosis using late gadolinium enhancement (LGE). Several multi-slice LGE sequences have been introduced for faster acquisition in patients with arrhythmia and insufficient breathhold capability. The aim of this study was to assess the accuracy of several multi-slice LGE sequences to detect and quantify myocardial fibrosis in patients with ischemic and non-ischemic myocardial disease. METHODS: Patients with known or suspected LGE due to chronic infarction, inflammatory myocardial disease and hypertrophic cardiomyopathy (HCM) were prospectively recruited. LGE images were acquired 10-20 min after administration of 0.2 mmol/kg gadolinium-based contrast agent. Three different LGE sequences were acquired: a segmented, single-slice/single-breath-hold fast low angle shot PSIR sequence (FLASH-PSIR), a multi-slice balanced steady-state free precession inversion recovery sequence (bSSFP-IR) and a multi-slice bSSFP PSIR sequence during breathhold and free breathing. Image quality was evaluated with a 4-point scoring system. Contrast-to-noise ratios (CNR) and acquisition time were evaluated. LGE was quantitatively assessed using a semi-automated threshold method. Differences in size of fibrosis were analyzed using Bland Altman analysis. RESULTS: Three hundred twelve patients were enrolled (n = 212 chronic infarction, n = 47 inflammatory myocardial disease, n = 53 HCM) Of which 201 patients (67,4%) had detectable LGE (n = 143 with chronic infarction, n = 27 with inflammatory heart disease and n = 31 with HCM). Image quality and CNR were best on multi-slice bSSFP-PSIR. Acquisition times were significantly shorter for all multi-slice sequences (bSSFP-IR: 23.4 +/- 7.2 s; bSSFP-PSIR: 21.9 +/- 6.4 s) as compared to FLASH-PSIR (361.5 +/- 95.33 s). There was no significant difference of mean LGE size for all sequences in all study groups (FLASH-PSIR: 8.96 +/- 10.64 g; bSSFP-IR: 8.69 +/- 10.75 g; bSSFP-PSIR: 9.05 +/- 10.84 g; bSSFP PSIR free breathing: 8.85 +/- 10.71 g, p > 0.05). LGE size was not affected by arrhythmia or absence of breathhold on multi-slice LGE sequences. CONCLUSIONS: Fast multi-slice and standard segmented LGE sequences are equivalent techniques for the assessment of myocardial fibrosis, independent of an ischemic or non ischemic etiology. Even in patients with arrhythmia and insufficient breathhold capability, multi-slice sequences yield excellent image quality at significantly reduced scan time and may be used as standard LGE approach.

AB - BACKGROUND: When using the microbial cell factories for green manufacturing, several important issues need to be addressed such as how to maintain the stability of biocatalysts used in the bioprocess and how to improve the synthetic efficiency of the biological system. One strategy widely used during natural evolution is the creation of organelles which can be used for regional control. This kind of compartmentalization strategy has inspired the design of artificial organelle-like nanodevice for synthetic biology and "green chemistry". RESULTS: Mimicking the natural concept of functional compartments, here we show that the engineered thermostable ketohydroxyglutarate aldolase from Thermotoga maritima could be developed as a general platform for nanoreactor design via supramolecular self-assembly. An industrial biocatalyst-(+)-gamma-lactamase was selected as a model catalyst and successful encapsulated in the nanoreactor with high copies. These nanomaterials could easily be synthesized by Escherichia coli by heterologous expression and subsequently self-assembles into the target organelle-like nanoreactors both in vivo and in vitro. By probing their structural characteristics via transmission electronic microscopy and their catalytic activity under diverse conditions, we proved that these nanoreactors could confer a significant benefit to the cargo proteins. The encapsulated protein exhibits significantly improved stability under conditions such as in the presence of organic solvent or proteases, and shows better substrate tolerance than free enzyme. CONCLUSIONS: Our biodesign strategy provides new methods to develop new catalytically active protein-nanoreactors and could easily be applied into other biocatalysts. These artificial organelles could have widely application in sustainable catalysis, synthetic biology and could significantly improve the performance of microbial cell factories. PMID- 29458432 TI - Physicians' knowledge, attitudes, and perceptions concerning antibiotic resistance: a survey in a Ghanaian tertiary care hospital. AB - BACKGROUND: Understanding the knowledge, attitudes and practices of physicians towards antibiotic resistance is key to developing interventions aimed at behavior change. The survey aimed to investigate physicians' knowledge and attitudes towards antibiotic resistance in a tertiary-care hospital setting in Ghana. METHODS: We conducted a cross-sectional respondent-driven survey using a 40-item, anonymous, voluntary, traditional paper-and-pencil self-administered questionnaire among 159 physicians at Korle-Bu Teaching Hospital. Single and multi-factor analysis were conducted to assess the study objectives. RESULTS: The survey was completed by 159 of 200 physicians (response rate of 79.5%). Of physicians, 30.1% (47/156) perceived antibiotic resistance as very important global problem, 18.5% (29/157) perceived it as very important national problem and only 8.9% (14/157) thought it as a very important problem in their hospital. Methicillin resistant Staphylococcus aureus was the most known about antibiotic resistant bacteria of public health importance followed by extended-spectrum beta lactamase-producing Enterobacteriaceae, carbapenem resistant Enterobacteriaceae (CRE) and vancomycin resistant enterococci (VRE). In multiple logistic regression analysis, senior physicians were nearly 3 times more likely to know about CRE than junior physicians. The odds of knowing about VRE increased over 4.5 times from being a junior to becoming senior physician. Among junior physicians, age had no associated effect on their knowledge of VRE or CRE. CONCLUSIONS: Physicians in this survey showed variable knowledge and perceptions on antibiotic resistance. Introducing educational programs on antibiotic resistance would be a useful intervention and should focus on junior physicians. PMID- 29458433 TI - Computational analysis identifies putative prognostic biomarkers of pathological scarring in skin wounds. AB - BACKGROUND: Pathological scarring in wounds is a prevalent clinical outcome with limited prognostic options. The objective of this study was to investigate whether cellular signaling proteins could be used as prognostic biomarkers of pathological scarring in traumatic skin wounds. METHODS: We used our previously developed and validated computational model of injury-initiated wound healing to simulate the time courses for platelets, 6 cell types, and 21 proteins involved in the inflammatory and proliferative phases of wound healing. Next, we analysed thousands of simulated wound-healing scenarios to identify those that resulted in pathological (i.e., excessive) scarring. Then, we identified candidate proteins that were elevated (or decreased) at the early stages of wound healing in those simulations and could therefore serve as predictive biomarkers of pathological scarring outcomes. Finally, we performed logistic regression analysis and calculated the area under the receiver operating characteristic curve to quantitatively assess the predictive accuracy of the model-identified putative biomarkers. RESULTS: We identified three proteins (interleukin-10, tissue inhibitor of matrix metalloproteinase-1, and fibronectin) whose levels were elevated in pathological scars as early as 2 weeks post-wounding and could predict a pathological scarring outcome occurring 40 days after wounding with 80% accuracy. CONCLUSION: Our method for predicting putative prognostic wound-outcome biomarkers may serve as an effective means to guide the identification of proteins predictive of pathological scarring. PMID- 29458434 TI - The German version of the Expanded Prostate Cancer Index Composite (EPIC): translation, validation and minimal important difference estimation. AB - BACKGROUND: No official German translation exists for the 50-item Expanded Prostate Cancer Index Composite (EPIC), and no minimal important difference (MID) has been established yet. The aim of the study was to translate and validate a German version of the EPIC with cultural adaptation to the different German speaking countries and to establish the MID. METHODS: We translated and culturally adapted the EPIC into German. For validation, we included a consecutive subsample of 92 patients with localized prostate cancer undergoing radical prostatectomy who participated the Prostate Cancer Outcomes Cohort. Baseline and follow-up assessments took place before and six weeks after prostatectomy in 2010 and 2011. We assessed the EPIC, EORTC QLQ-PR25, Feeling Thermometer, SF-36 and a global rating of health state change variable. We calculated the internal consistency, test-retest reliability, construct validity, responsiveness and MID. RESULTS: For most EPIC domains and subscales, our a priori defined criteria for reliability were fulfilled (construct reliability: Cronbach's alpha 0.7-0.9; test-retest reliability: intraclass-correlation coefficient >= 0.7). Cross-sectional and longitudinal correlations between EPIC and EORTC QLQ-PR25 domains ranged from 0.14-0.79, and 0.06-0.5 and 0.08-0.72 for Feeling Thermometer and SF-36, respectively. We established MID values of 10, 4, 12, and 6 for the urinary, bowel, sexual and hormonal domain. CONCLUSION: The German version of the EPIC is reliable, responsive and valid to measure HRQL in prostate cancer patients and is now available in German language. With the suggested MID we provide interpretation to what extent changes in HRQL are clinically relevant for patients. Hence, study results are of interest beyond German speaking countries. PMID- 29458435 TI - Long-term effects on the progress of neuropathy after diabetic Charcot foot: an 8.5-year prospective case-control study. AB - OBJECTIVE: Charcot foot is a severe complication to diabetes mellitus, associated with diabetic neuropathy. Any long-term effects of a Charcot foot on the progress of neuropathy are still largely unexplored. The objective was to investigate whether a previous Charcot foot had any long-term effects on the progress of neuropathy. RESULTS: An 8.5-year follow-up case-control study of 49 individuals with diabetes mellitus, 24 of whom also had Charcot foot at baseline visit in 2005-2007. Neuropathy was assessed with a questionnaire, biothesiometry, heart rate variability and venous occlusion plethysmography. Of the 49 baseline participants, 22 were able to participate in the follow-up. Twelve had passed away in the meantime. Heart rate variability was unchanged in both groups; from 9.7 to 7.2 beats/min (p = 0.053) in the Charcot group, and 14.3 to 12.6 beats/min (p = 0.762) in the control group. Somato-sensoric neuropathy showed no difference between baseline and follow-up in the Charcot group (from 39.1 to 38.5 V) (p = 0.946), but a significantly worsened sensitivity in the control group (from 25.1 to 38.9 V) (p = 0.002). In conclusion, we found that any differences in somatic or cardial autonomic neuropathy present at baseline had disappeared at follow-up after 8.5 years. PMID- 29458436 TI - Immunoregulatory functions and the therapeutic implications of GARP-TGF-beta in inflammation and cancer. AB - GARP (glycoprotein-A repetitions predominant) is a type I transmembrane cell surface docking receptor for latent transforming growth factor-beta (TGF-beta) that is abundantly expressed on regulatory T lymphocytes and platelets. GARP regulates the availability of membrane-bound latent TGF-beta and modulates its activation. For this reason, GARP expression on immune and non-immune cells is involved in maintaining peripheral tolerance. It plays an important role in preventing inflammatory diseases such as allergy and graft versus host disease (GvHD). GARP is also frequently hijacked by cancer cells to promote oncogenesis. This review summarizes the most important features of GARP biology described to date including gene regulation, protein expression and mechanism in activating latent TGF-beta, and the function of GARP in regulatory T cell biology and peripheral tolerance, as well as GARP's increasingly recognized roles in platelet mediated cancer immune evasion. The promise for GARP-targeted strategy as a novel immunotherapy of cancer is also highlighted. PMID- 29458437 TI - Ablation of caspase-1 protects against TBI-induced pyroptosis in vitro and in vivo. AB - BACKGROUND: Traumatic brain injury (TBI) is a critical public health and socioeconomic problem throughout the world. Inflammation-induced secondary injury is one of the vital pathogenic parameters of TBI. Molecular signaling cascades of pyroptosis, a specific type of cellular necrosis, are key drivers of TBI-induced inflammation. METHODS: In this study, mice with genetically ablated caspase-1 (caspase-1-/-) were subjected to controlled cortical impact injury in vivo, and primary neuron deficient in caspase-1 through siRNA knockdown and pharmacologic inhibition was stimulated by mechanical scratch, equiaxial stretch, and LPS/ATP in vitro. We evaluated the effects of caspase-1 deficiency on neurological deficits, inflammatory factors, histopathology, cell apoptosis, and pyroptosis. RESULTS: During the acute post-injury period (0-48 h) in vivo, motor deficits, anti-inflammatory cytokines (TGF-beta and IL-10), pro-inflammatory cytokines (IFN gamma, IL-1beta, and IL-18), and blood lactate dehydrogenase (LDH), as well as pyroptosis-related proteins (caspase-1, caspase-1 fragments, caspase-11 and GSDMD), were increased. Caspase-1 was activated in the cortex of TBI mice. Inflammatory activation was more profound in injured wild-type mice than in caspase-1-/- mice. In vitro, mechanical scratch, equiaxial stretch, and LPS/ATP induced neuron pyroptosis, apoptosis, LDH release, and increased expression of inflammatory factors. The effects of mechanical and inflammatory stress were reduced through inhibition of caspase-1 activity through siRNA knockdown and pharmacologic inhibition. CONCLUSION: Collectively, these data demonstrate that pyroptosis is involved in neuroinflammation and neuronal injury after TBI, and ablation of caspase-1 inhibits TBI-induced pyroptosis. Our findings suggest that caspase-1 may be a potential target for TBI therapy. PMID- 29458438 TI - Aspirin is associated with low oral pH levels and antacid helps to increase oral pH. AB - OBJECTIVE: Aspirin is a commonly used medicine for primary and secondary prevention of cardiovascular diseases. It is an acidic medicine associated with gastric irritation and acid reflux, which in turn can lead to low oral pH levels. Therefore, it is important to understand the association between aspirin and oral pH levels in order to achieve an optimum oral health condition among patients who take aspirin on prescription. RESULTS: Out of 373 patients, 162 (44%) were males and 245 (66%) were on aspirin. 71% of aspirin taking patients and 29% of non aspirin taking patients had oral pH less than 6.5 (P < 0.01). Aspirin showed a significant association with low oral pH levels (odds ratio = 1.91, 95% CI 1.23 2.99, P < 0.01). 78 patients were given antacids and followed up for 4 weeks, 63 of them (81%) showed an improvement in oral pH and the improvement was marked in the group who had oral pH between 5.5-6.0 compared to the group who had oral pH between 6.0-6.5 (P = 0.03). The results show that aspirin therapy is associated with low oral pH and administration of an antacid with aspirin helps to increase the oral pH level. PMID- 29458439 TI - Efficacy and safety assessment of a water-soluble formulation of fluralaner for treatment of natural Ornithonyssus sylviarum infestations in laying hens. AB - BACKGROUND: Northern fowl mite, Ornithonyssus sylviarum (Canestrini & Fanzago, 1877), infestations can stress birds, impairing welfare and causing substantial economic losses. A study was undertaken to determine the efficacy of an ectoparasiticide solution (fluralaner) for oral administration in the treatment of mite-infested hens. METHODS: Clinically healthy, naturally mite-infested laying hens (n = 132), approximately 32 weeks of age, were ranked by Day -9 mite vent counts and randomized among 12 study pens, each to hold one of four treatment groups. Three groups received fluralaner-medicated water by oral gavage at dose rates of 0.25, 0.5 or 1.0 mg/kg on Days 0 and 7; one group was an untreated control (three pens for each group). Five naturally infested untreated birds were included in each pen to act as mite-infested source birds. Thus each pen, treated and control, had six non-source birds for assessment of efficacy, plus five source birds to provide ongoing challenge. Primary efficacy assessments were based on mean O. sylviarum vent counts from non-source birds in the control and treated group pens on Days 1, 2, 6, 8, 12, 15, 19, 22 and 26. RESULTS: Source birds maintained infestations throughout the study, validating the challenge to study birds. On Days 1 through 22, mean control group mite counts were significantly greater than those of the treated groups (P <= 0.013). Relative to the control group, mean O. sylviarum counts were reduced by at least 90% from Day 6 through Days 19, 22 and 22 in the fluralaner 0.25, 0.5 and 1.0 mg/kg groups, respectively. On Day 19, mean mite counts were lower in the 0.5 and 1.0 mg/kg groups compared with the 0.25 mg/kg group (P <= 0.018), and in the 1.0 mg/kg compared with the 0.5 mg/kg group (P = 0.014). There were no adverse events in treated birds. CONCLUSIONS: A fluralaner solution administered twice by gavage to laying hens with a one-week between-treatment interval was safe and effective in quickly controlling O. sylviarum infestations despite continuous challenge from infested birds. By eliminating mites, this fluralaner solution has the potential to improve bird health and productivity, and to eliminate the burden of topical pesticide application.

AB - Following publication of the original article [1], the authors reported that there was a mistake in the Methods section -> Measurements of biomarkers (page 6, line 3): 2000g should read 2500g. So, the correct sentence should be "All samples were obtained by venipuncture into serum monovettes(r) and centrifuged at 2500g for 10 min at 20 degrees C." PMID- 29458440 TI - Agreement of self- and physician-collected samples for detection of high-risk human papillomavirus infections in women attending a colposcopy clinic in Thailand. AB - OBJECTIVE: To study the concordance between vaginal self- and endocervical physician-collected high-risk (hr) HPV testing in Thai women who attended a colposcopy clinic. Vaginal samples were obtained by self-sampling with a dry brush before endocervical samples were obtained by physicians. Both specimens were analyzed for hrHPV by Cobas4800 HPV test. RESULTS: Of the 247 pairs of samples, overall hrHPV prevalence from self- and physician-collected samples was 41.3 and 36.0%, respectively. The overall agreement between the methods was 74.5% with kappa 0.46 (P < 0.001). Our study revealed moderate agreement between self- and physician-collected methods for hrHPV testing. PMID- 29458442 TI - Socio-economic differences in the change of fruit and vegetable intakes among Dutch adults between 2004 and 2011: the GLOBE study. AB - OBJECTIVE: To investigate socio-economic differences in changes in fruit and vegetable intake between 2004 and 2011 and explore the mediating role of financial barriers in this change. DESIGN: Respondents completed a self-reported questionnaire in 2004 and 2011, including questions on fruit and vegetable intake (frequency per week), indicators of socio-economic position (education, income) and perceived financial barriers (fruits/vegetables are expensive, financial distress). Associations were analysed using ordinal logistic regression. The mediating role of financial barriers in the association between socio-economic position and change in fruit and vegetable intake was studied with the Baron and Kenny approach. SETTING: Longitudinal GLOBE study. SUBJECTS: A total of 2978 Dutch adults aged 25-75 years. RESULTS: Respondents with the lowest income in 2004 were more likely to report a decrease in intake of cooked vegetables (P trend<0.001) and raw vegetables (P-trend<0.001) between 2004 and 2011, compared with those with the highest income level. Respondents with the lowest education level in 2004 were more likely to report a decrease in intake of fruits (P trend=0.021), cooked vegetables (P-trend=0.033), raw vegetables (P-trend<0.001) and fruit juice (P-trend=0.027) between 2004 and 2011, compared with those with the highest education level. Financial barriers partially mediated the association between income and education and the decrease in fruit and cooked vegetable intake between 2004 and 2011. CONCLUSIONS: These results show a widening of relative income and educational differences in fruit and vegetable intake between 2004 and 2011. Financial barriers explained a small part of this widening. PMID- 29458443 TI - Epidemiology and control measures of an OXA-48-producing Enterobacteriaceae hospital-wide oligoclonal outbreak. AB - The main objective of our study was to describe the epidemiological and microbiological features of an oligoclonal hospital-wide outbreak caused by OXA 48-producing Enterobacteriaceae (OXA-48-PE). OXA-48 is a carbapenemase belonging to Ambler class D beta-lactamases, identified frequently in the Mediterranean and Southern European countries, and associated with several Enterobacteriaceae species. An outbreak of OXA-48-PE with a complex epidemic pattern was detected in January 2011. Initial control measures included contact precautions and the reinforcement of infection control practices, but despite all efforts made, the epidemiological situation hardly changed and new measures were implemented during 2013. An observational retrospective study was performed to describe the main features of the outbreak and to analyse the cumulative incidence (CI) trends. Eight hundred and 16 patients colonised or infected by OXA-48-PE were identified during the 2-year period (January 2013-December 2014), female 46%, mean age (s.d.), 71.6 (15.2). The samples isolated in the incident cases were rectal swabs (80%), urine samples (10.7%), blood samples (2.8%) and other clinical samples (6.6%). The most frequent OXA-48-PE was Klebsiella pneumoniae. Eleven different clones were identified, but K. pneumoniae sequence types 11 and 405 were predominant: ST11 (64.2%) and ST405 (29.3%). OXA-48-PE CI trend suffered a statistically significant change in August 2013, which continued the following months. Though we could not eradicate the outbreak, we observed a statistically significant drop in CI after an intervention for OXA-48-PE control, based on patient cohort, active surveillance, electronic alerts and reinforcement of infection control measures in a tertiary hospital. PMID- 29458444 TI - Dietary energy density is positively associated with body composition of adults in Southwest China. AB - OBJECTIVE: Dietary energy density (ED) might have influences on body composition. We therefore examined whether ED is associated with body composition among Chinese adults. DESIGN: We collected dietary data through validated two-day 24 h recalls. ED, defined as the amount of energy per unit weight of food consumed, was calculated based on five methods. Multiple linear regression analyses were performed to explore the associations between ED and body composition parameters, including BMI, fat mass index (FMI), fat-free mass index (FFMI), percentage body fat (%BF) and waist circumference (WC). SETTING: Southwest China. SUBJECTS: Chinese adults (n 1933) in 2013. RESULTS: After adjusting the covariates, all ED definitions were positively associated with BMI, FMI, FFMI, %BF and WC among women (P<0.01). In men, however, ED with foods only was positively associated with BMI, FMI, FFMI and %BF (P<0.05), but not with WC (P=0.07); we also found null associations between ED with foods and all beverages and body composition among men. Additionally, ED contributed to higher increases of body composition in women than in men (P<0.01). CONCLUSIONS: The present study supports the positive association between ED and body composition among adults in Southwest China, in which beverages may play an important role. PMID- 29458445 TI - Using a trauma-informed policy approach to create a resilient urban food system. AB - OBJECTIVE: Food insecurity is associated with toxic stress and adverse long-term physical and mental health outcomes. It can be experienced chronically and also triggered or exacerbated by natural and human-made hazards that destabilize the food system. The Baltimore Food System Resilience Advisory Report was created to strengthen the resilience of the city's food system and improve short- and long term food security. Recognizing food insecurity as a form of trauma, the report was developed using the principles of trauma-informed social policy. In the present paper, we examine how the report applied trauma-informed principles to policy development, discuss the challenges and benefits of using a trauma informed approach, and provide recommendations for others seeking to create trauma-informed food policy. DESIGN: Report recommendations were developed based on: semi-structured interviews with food system stakeholders; input from community members at outreach events; a literature review; Geographic Information System mapping; and other analyses. The present paper explores findings from the stakeholder interviews. SETTING: Baltimore, Maryland, USA. SUBJECTS: Baltimore food system stakeholders stratified by two informant categories: organizations focused on promoting food access (n 13) and community leaders (n 12). RESULTS: Stakeholder interviews informed the recommendations included in the report and supported the idea that chronic and acute food insecurity are experienced as trauma in the Baltimore community. CONCLUSIONS: Applying a trauma-informed approach to the development of the Baltimore Food System Resilience Advisory Report contributed to policy recommendations that were community-informed and designed to lessen the traumatic impact of food insecurity. PMID- 29458446 TI - Early development and reproductive lifespan of rabbit females: implications of growth rate, rearing diet and body condition at first mating. AB - Factors influencing early development such as birth weight, nest competition, and the diet received during rearing have been proposed as elements conditioning the future reproductive performance of European rabbit (Oryctolagus cuniculus) females. To evaluate their effects, we followed the life of 1513 females from birth to time of death, culling or censoring (animals alive at a fixed date). Between 0 and 63 days of age 353 females died. From the remaining 1160 females, 864 were chosen based on their birth weight to be transferred from the selection to the production farm. At this farm, 431 females received the control diet (184 g of CP, 381 g of NDF and 11.8 MJ of DE per kg DM), while the other 433 received the fibrous diet (134 g of CP, 436 g of NDF and 10.0 MJ of DE per kg DM). Throughout the rearing period, we checked for the individual live weight and body condition (perirenal fat thickness) at first artificial insemination. Reproductive lifespan was defined as the number of days between the first parturition and the time of death, culling or censoring. Birth weight affected the survival of newborn females during lactation and the presence of a milk spot at birth (related to nest competition) increased the survivability of newborns weighing <45 g (P<0.001). Rearing diet altered the growth curve of females and their body condition at first insemination. The diet also altered the relative risk of death during the rearing period, which was lower among females fed on the fibrous diet (-12.5%; P<0.001). Therefore, a higher number of females fed with this diet reached their reproductive life, directly affecting the productivity measured per housed female. Fatter females at first insemination had smaller litter sizes and a higher risk of being culled than lean ones (P<0.05). In general, the fibrous diet reduced the risk of leaving the herd at early rearing, and both birth weight and perirenal fat thickness affected female's reproductive lifespan. An excess of fat (positive change in one unit of perirenal fat) at their first insemination represented an increased the risk of death or elimination of 13%.

AB - OBJECTIVE: The present study aimed to evaluate salt-reduction education using a self-monitoring urinary salt-excretion device. DESIGN: Parallel, randomized trial involving two groups. The following parameters were checked at baseline and endline of the intervention: salt check sheet, eating behaviour questionnaire, 24 h home urine collection, blood pressure before and after urine collection. SETTING: The intervention group self-monitored urine salt excretion using a self measuring device for 4 weeks. In the control group, urine salt excretion was measured, but the individuals were not informed of the result. SUBJECTS: Seventy eight individuals (control group, n 36; intervention group, n 42) collected two 24 h urine samples from a target population of 123 local resident volunteers. The samples were then analysed. RESULTS: There were no differences in clinical background or related parameters between the two groups. The 24 h urinary Na:K ratio showed a significant decrease in the intervention group (-1.1) compared with the control group (-0.0; P=0.033). Blood pressure did not change in either group. The results of the salt check sheet did not change in the control group but were significantly lower in the intervention group. The score of the eating behaviour questionnaire did not change in the control group, but the intervention group showed a significant increase in eating behaviour stage. CONCLUSIONS: Self monitoring of urinary salt excretion helps to improve 24 h urinary Na:K, salt check sheet scores and stage of eating behaviour. Thus, usage of self-monitoring tools has an educational potential in salt intake reduction.

AB - This study evaluated the impact of maternal vaccination against rubella on the levels of specific rubella IgG (rIgG) in 198 newborn cord sera samples. Detailed maternal vaccination data were available. Specific rIgG was measured using a commercial enzyme immunoassay. Most mothers (78.8%) had been vaccinated against rubella at least once in their lives. In 15 (7.6%) cord sera samples, the concentration of specific rIgG was below 11 IU/ml, which was classified as seronegative. Statistical analysis using multiple logistic regression (n = 198) showed that newborns of mothers born between 1986 and 1995, and those born to unvaccinated mothers, were more likely to be seronegative (odds ratio (ORs) 5.2 and 4.9, respectively, adjusted for sex and gestational age). For vaccinated mothers (n = 156), those born between 1986 and 1995 were more likely to have seronegative newborns (OR 11.5 adjusting for sex, gestational age and time since last vaccination). Mothers of the 15 (7.6%) seronegative newborns might have been susceptible to rubella during pregnancy. Checking the vaccination status therefore recommended. PMID- 29458449 TI - Veterans Health Administration's Disaster Emergency Medical Personnel System (DEMPS) Training Evaluation: Potential Implications for Disaster Health Care Volunteers. AB - OBJECTIVE: The US Veterans Health Administration's Disaster Emergency Medical Personnel System (DEMPS) is a team of employee disaster response volunteers who provide clinical and non-clinical staffing assistance when local systems are overwhelmed. This study evaluated attitudes and recommendations of the DEMPS program to understand the impact of multi-modal training on volunteer perceptions. METHODS: DEMPS volunteers completed an electronic survey in 2012 (n=2120). Three training modes were evaluated: online, field exercise, and face to-face. Measures included: "Training Satisfaction," "Attitudes about Training," "Continued Engagement in DEMPS." Data were analyzed using chi2 and logistic regression. Open-ended questions were evaluated in a manner consistent with grounded theory methodology. RESULTS: Most respondents participated in DEMPS training (80%). Volunteers with multi-modal training who completed all 3 modes (14%) were significantly more likely to have positive attitudes about training, plan to continue as volunteers, and would recommend DEMPS to others (P value<0.001). Some respondents requested additional interactive activities and suggested increased availability of training may improve volunteer engagement. CONCLUSIONS: A blended learning environment using multi-modal training methods, could enhance satisfaction and attitudes and possibly encourage continued engagement in DEMPS or similar programs. DEMPS training program modifications in 2015 expanded this blended learning approach through new interactive online learning opportunities.

PMID- 29458450 TI - Transcriptomic and metabolomic responses induced in the livers of growing pigs by a short-term intravenous infusion of sodium butyrate. AB - Previous studies showed that butyrate played benefit roles in the health and metabolism of animals. However, little information on the effects of butyrate on the metabolism of piglets at the extraintestinal level is available. The present study investigated transcriptomic and metabolomic responses in the livers of pigs to evaluate the effects of intravenous sodium butyrate (SB) on the body's metabolism at the extraintestinal level. A total of 12 Duroc*Landrace*Large White growing barrows (60 days of age) fitted with jugular vein cannula were randomly allocated to either the SB group or the control (CO) group. Pigs in the SB group were intravenously infused with 10 ml SB (200 mmol/l) for 7 days, whereas pigs in the CO group were treated with the same amount of saline. The livers of pigs were collected for gene expression and metabolome analyses. The RNA sequencing (RNA Seq) analysis showed that the mRNA expression of Acyl-CoA synthetase long-chain family member 1 (ACSL1), carnitine palmitoyltransferase 1A (CPT1A), acetyl-CoA acyltransferase 2 (ACAA2) and phosphoenolpyruvate carboxykinase 1 (PCK1) were downregulated (Q<0.05), whereas fatty acid binding protein 1 (FABP1) and cytochrome P450 family 7 subfamily A member 1 (CYP7A1) were upregulated (P<0.05) by SB treatment, indicating a decrease in fatty acid oxidation and gluconeogenesis and an increase in fatty acid transportation and cholesterol metabolism. Gas chromatography-mass spectrometry analysis showed that raffinose was enriched in the SB group compared with the CO group, indicating a decrease in metabolism of galactose. Moreover, SB treatment significantly decreased the concentration of blood cholesterol. The results suggest that a short-term intravenous infusion of SB could modulate hepatic lipid metabolism by decreasing fatty acid oxidation and increasing fatty acid transportation and cholesterol metabolism. PMID- 29458451 TI - Increasing Perceived Emergency Preparedness by Participatory Policy-Making (Think Tanks). AB - OBJECTIVE: The study aimed to examine impact of think-tanks designed to create policies for emerging threats on medical teams' perceptions of individual and systemic emergency preparedness. METHODS: Multi-professional think-tanks were established to design policies for potential attacks on civilian communities. In total, 59 multi-sector health care managers participated in think-tanks focused on: (a) primary care services in risk zones; (b) hospital care; (c) casualty evacuation policies; (d) medical services to special-needs populations; and (e) services in a "temporary military-closed zone." Participants rotated systematically between think-tanks. Perceived individual and systemic emergency preparedness was reviewed pre-post participation in think-tanks. RESULTS: A significant increase in perceived emergency preparedness pre-post-think-tanks was found in 8/10 elements including in perceived individual role proficiency (3.71+/ 0.67 vs 4.60+/-0.53, respectively; P<0.001) and confidence in colleagues' proficiency during crisis (3.56+/-0.75 vs 4.37+/-0.61, respectively; P<0.001). Individual preparedness and role perception correlates with systemic preparedness and proficiency in risk assessment. CONCLUSIONS: Participation in policy-making impacts on individuals' perceptions of empowerment including trust in colleagues' capacities, but does not increase confidence in a system's preparedness. Field and managerial officials should be involved in policy-making processes, as a means to empower health care managers and improve interfaces and self-efficacy that are relevant to preparedness and response for crises.

AB - OBJECTIVE: This study aimed to examine factors associated with receipt of post disaster support from network (eg, family or friends) and non-network (eg, government agencies) sources. METHODS: Participants (n=409) were from a population-based sample of Hurricane Sandy survivors surveyed 25-28 months post disaster. Survivors were asked to imagine a future disaster and indicate how much they would depend on network and non-network sources of support. In addition, they reported on demographic characteristics, disaster-related exposure, post traumatic stress, and depression. Information on the economic and social resources in survivors' communities was also collected. RESULTS: Multilevel multivariable regression models found that lack of insurance coverage and residence in a neighborhood wherein more persons lived alone were associated with survivors anticipating less network and non-network support. In addition, being married or cohabiting was significantly associated with more anticipated network support, whereas older age and having a high school education or less were significantly associated with less anticipated network support. CONCLUSIONS: By having survivors anticipate a future disaster scenario, this study provides insight into predictors of post-disaster receipt of network and non-network support. Further research is needed to examine how these findings correspond to survivors' received support in the aftermath of future disasters. (Disaster Med Public Health Preparedness. 2018;page 1 of 7). PMID- 29458453 TI - Consumer accounts of favourable dietary behaviour change and comparison with official dietary guidelines. AB - OBJECTIVE: The current study aimed to assess Uruguayan consumers' accounts of their own need to change their dietary patterns, their intended changes and the barriers related to doing so, and to compare the intentions and barriers with the recommendations of the national dietary guidelines. DESIGN: An online survey with 2381 Uruguayan employed adults, aged between 18 and 65 years, 65 % females, was conducted. Participants had to answer two open-ended questions related to changes they could make in the foods they eat and/or the way in which they eat to improve the quality of their diet and the reasons why they had not implemented those changes yet. Content analysis using inductive coding by two researchers was used to analyse the responses. RESULTS: Consumers mainly intended to change consumption of types of foods, particularly eating more fruits, vegetables and legumes and consuming less flour, but also intended to alter their eating patterns. Lack of time and the fact that healthy foods are perceived as being more expensive than unhealthy foods were major barriers to behaviour change. Some of the recommendations of the dietary guidelines, particularly those related to enjoying cooking and meals and engaging in it as a social activity, were not represented in consumer accounts. CONCLUSIONS: Accompanying policies to the dietary guidelines need to underline the importance of changes in dietary patterns, including greater enjoyment and sharing food preparation and meals in the company with others, address misconceptions about flour, and provide concrete, consumer-derived recommendations on how to enact the guidelines. PMID- 29458454 TI - Setting Targets for Emergency Preparedness for a Jurisdiction's Whole Health Care System: The Approach Taken by New York City's Department of Health and Mental Hygiene. AB - There is little existing in the literature that provides a definition of readiness for a jurisdiction's whole health care system. As defining readiness at the system level has proven to be challenging, an approach that provides a framework for planning and measuring health care readiness with broad utility is needed. The New York City Department of Health and Mental Hygiene (DOHMH) devised the Readiness Target Project. Nine areas or dimensions of readiness emerged from this work. Through focus groups and feedback from hospital stakeholders DOHMH developed a matrix of readiness areas outlining current state, target state, gaps, and recommendations to achieve readiness. The matrix is in use as a systematic approach to discover and close gaps in the readiness of the whole health care system and to provide that system a locally valid framework to drive continuous improvement. This paper describes a framework for planning and determining the status of health care readiness at the system level for the jurisdiction.

AB - OBJECTIVE: Natural disasters have a significant impact on the health sector. On April 25, 2015, Nepal was struck by a 7.8 magnitude earthquake. The aim of the study was to compare patient volumes and clinical conditions presenting to the emergency department pre- and post-earthquake. METHODS: A retrospective study was done at Patan Hospital Emergency Department in Kathmandu, Nepal. Volume, demographics, and patient diagnoses were collected for 4 months post-disaster and compared with cases seen the same months the year before the disaster to control for seasonal variations. RESULTS: After the 2015 Nepal earthquake, 12,180 patients were seen in the emergency department. This was a significant decrease in patient volume compared with the 14,971 patients seen during the same months in 2014 (P=0.04). Of those, 5496 patients (4093 pre-disaster and 1433 post disaster) had a chief complaint or diagnosis recorded for analysis. An increase in cardiovascular and respiratory cases was seen as well as an increase in psychiatric cases (mostly alcohol related) and cases of anemia. There was a decrease in the number of obstetrics/gynecology, infectious disease, and poisoning cases post-earthquake. CONCLUSIONS: Understanding emergency department utilization after the earthquake has the potential to give further insight into improving disaster preparedness plans for post-disaster health needs.

AB - BACKGROUND: Omalizumab was approved for the treatment of chronic idiopathic urticaria (CIU)/chronic spontaneous urticaria (CSU) in the United States in March 2014. OBJECTIVE: This study sought to describe real-world omalizumab use, in the United States, in a large cohort of patients with CIU/CSU. METHODS: Patients with CIU/CSU (ages >=12 years) initiated on omalizumab (index date) with >=12 months of pre- and postindex data were identified in the an insurance claims data base (January 1, 2013, to July 31, 2016). Treatment patterns, including the dosing regimen and continuous use of omalizumab (no gaps for >=60 days), were described during the 12-month postindex follow-up period. RESULTS: A total of 1546 patients (mean +/- standard deviation [SD] ages, 44 +/- 14.5 years; 73.1% women) were identified. Most of the patients (84.5%) were initiated on omalizumab 300-mg dose; 90% maintained the initial dose, 7.5% had a dose increase, and 4.6% had a dose decrease. The mean +/- SD omalizumab treatment duration was 9.1 +/- 3.8 months, the mean +/- SD number of omalizumab administrations was 8.3 +/- 4.8, and the mean +/- SD administration frequency was 44 +/- 29 days. A proportion of the patients continuously treated with omalizumab for 6, 9, and 12 months was 67.3, 54.8, and 47.4%, respectively. Among the patients who discontinued omalizumab for >=3 months (39.8%), 21% restarted the treatment after a mean +/- SD of 4.4 +/- 1.3 months. The proportion of patients who used other CIU/CSU-related medications decreased pre- to postindex (94.8 to 81.1%), with the highest decrease observed in oral corticosteroids (75.7 to 49.9%). CONCLUSION: In this large real-world study, the majority of the patients with CIU/CSU were initiated on a 300-mg omalizumab dose and treated without titration up or down for 9 months on average. Most of the patients were continuously treated with omalizumab for >=6 months, and one-fourth of the patients who discontinued treatment resumed it. Moreover, compared with baseline levels, the use of other CIU/CSU-related medications was lower after omalizumab initiation, with the most prominent decrease observed in oral corticosteroids. PMID- 29458457 TI - Brevundimonas humi sp. nov., an alphaproteobacterium isolated from forest soil. AB - During a study of bacterial diversity of soil, a novel strain, CA-15T, was isolated from Kyonggi University forest soil. Cells were aerobic, Gram-stain negative, motile, non-spore-forming, rod-shaped, oxidase-positive and catalase- negative. Tyrosine was not oxidized but produced red pigmentation on an agar palte. Strain CA-15T hydrolysed Tween 60 and DNA. It grew at 15-35 degrees C (optimum, 25-30 degrees C), pH 6.0-10.0 (optimum, 7.0-9.0) and at 1.5 % (w/v) NaCl concentration. Phylogenetic analysis based on its 16S rRNA gene sequence indicated that strain CA-15T formed a lineage within the family Caulobacteraceae of the class Alphaproteobacteria that was distinct from various species of the genus Brevundimonas. Brevundimonas bullata DSM 7126T was the closest member of strain CA-15T on the basis of 16S rRNA gene sequence similarity (98.48 %). Q-10 was only an isoprenoid quinone detected for strain CA-15T. The major polar lipids were 1,2-di-O-acyl-3-O-[d-glucopyranosyl-(1->4)-alphad glucopyranuronosyl]glycerol, 1,2-di-O-acyl-3-O-[alphad-glucopyranosyl]-sn glycerol, 1,2-di-O-acyl-3-O-alphad-glucopyranuronosylglycerol, 1,2-diacyl-3-O-[6' phosphatidyl-alphad-glucopyranosyl]glycerol and phosphatidylglycerol. The major cellular fatty acids were summed feature 8 (C18 : 1omega7c and/or C18 : 1omega6c), C16 : 0, C18 : 1omega7c 11-methyl and C17 : 1omega8c. The DNA G+C content of strain CA-15T was 63.6 mol%. The polyphasic characterization indicated that strain CA-15T represents a novel species in the genus Brevundimonas, for which the name Brevundimonas humi sp. nov. is proposed. The type strain of Brevundimonas humi is CA-15T (=KEMB 9005-528T=KACC 19106T=NBRC 112677T). PMID- 29458458 TI - Nannocystis konarekensis sp. nov., a novel myxobacterium from an Iranian desert. AB - An orange-coloured myxobacterium, MNa11734T, was isolated from desert in Iran. MNa11734T had rod-shaped vegetative cells, moved by gliding and was bacteriolytic. No real fruiting body formation could be observed, but sporangioles were produced on water agar. The strain was mesophilic, strictly aerobic and chemoheterotrophic. 16S rRNA gene analyses revealed that MNa11734T belonged to the family Nannocystaceae, genus Nannocystis and was closely related to Nannocystis pusilla Na p29T (DSM 14622T) and Nannocystis exedens Na e1T (DSM 71T), with 97.8 and 97.6 % 16S rRNA gene sequence similarity, respectively. Laboratory-measured DNA-DNA hybridization showed only 9.5/15.7 % (reciprocal) similarity between the novel strain and N. pusilla Na p29T, and 14.1/20.4 % between the strain and N. exedens Na e1T, whereas DNA-DNA hybridization estimates derived from draft genome sequences were 21.8-23.0 % and 22.2-23.7 %, respectively, depending on the calculation method. The G+C content of DNA from Nannocystis konarekensis MNa11734T was 73.3 mol%, for N. pusilla Nap29T it was 71.8 mol% and for N. exedens Nae1T it was 72.2 mol%. The major fatty acids of the new strain were C16 : 1 (56.2 %), iso-C17 : 0 (14.4 %), C14 : 0 (8.2 %), C16 : 0 (6.6 %) and iso-C15 : 0 (5.9 %). Strain MNa11734T exhibited phylogenetic and physiological similarities to the two other species of Nannocystis, i.e. N. pusilla and N. exedens, but the differences were sufficient enough to represent a novel species, for which the name Nannocystiskonarekensis sp. nov. is proposed. The type strain is MNa11734T (=DSM 104509T=NCCB 100618T). PMID- 29458459 TI - Tritonibacter horizontis gen. nov., sp. nov., a member of the Rhodobacteraceae, isolated from the Deepwater Horizon oil spill. AB - A heterotrophic, Gram-stain-negative, aerobic, sodium-requiring and motile bacterium was isolated from oil-contaminated surface water of the Gulf of Mexico during the Deepwater Horizon oil spill. Strain O3.65T showed highest 16S rRNA gene sequence similarity to Phaeobacter gallaeciensis BS107T and Phaeobacter inhibens T5T, both with 98.3 %, respectively. Based on complete genome analysis, highest similarity was observed to species of the genus Ruegeria. Strain O3.65T exhibited a broad salinity, temperature and pH range of 0.5-10 % NaCl, 4-45 degrees C and 5.5-9.0, respectively. The DNA G+C content of strain O3.65T was 61.5 mol%. The major respiratory lipoquinone was ubiquinone-10 (Q-10), the most dominant fatty acids (>1 %) comprised 18 : 1omega7c and 18 : 1omega7c 11-methyl, 10 : 0 3OH, 12 : 1 3OH, 14 : 1 3OH/3-oxo-14 : 0, 16 : 0, 16 : 0 2OH, 18 : 1 2OH and 12 : 1. The polar lipid pattern indicated presence of phosphatidylcholine, phosphatidylglycerol, an unidentified aminolipid, two unidentified phospholipids and seven unidentified lipids. On Difco marine broth agar, strain O3.65T formed smooth, shiny white to beige and convex colonies with regular edges. Phylogenetic, phylogenomic and phenotypic differences revealed that strain O3.65T represents a new species of a novel genus within the family Rhodobacteraceae, for which we propose the name Tritonibacter horizontis gen. nov., sp. nov. The type strain of the type species is O3.65T (=DSM 101689T=LMG 29740T). PMID- 29458460 TI - Arenibacter catalasegens sp. nov., isolated from marine surface sediment, and emended description of the genus Arenibacter. AB - A Gram-staining-negative, aerobic, non-motile, rod-shaped bacterium, designated as P308H10T, was isolated from surface sediment of the Southern Indian Ocean. Growth occurred at 4-36 degrees C (optimum 20-25 degrees C), pH 6.0-8.5 (optimum 7.5-8.0) and in the presence of 1-8 % (w/v) NaCl (optimum 2-3 %). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain P308H10T lies within the clade of members of the genus Arenibacter and is closely related to Arenibacterhampyeongensis HP12T (98.0 %), Arenibacterechinorum KMM 6032T (98.4 %), Arenibacterpalladensis LMG 21972T (97.9 %), Arenibactertroitsensis KMM 3674T (97.9 %) and 'Arenibacter algicola' TG409 (98.1 %). The average nucleotide identity and digital DNA-DNA hybridization values between strain P308H10T and the five reference strains were 85.9-80.6 % and 30.2 23.6 %, respectively. The major fatty acids (>10 %) of strain P308H10T were summed feature 3, iso-C17 : 0 3-OH, iso-C15 : 1 G and iso-C15 : 0. The major polar lipids comprised phosphatidylethanolamine, five unidentified aminolipids and four unidentified lipids. The only respiratory quinone was menaquinone-6. The genomic DNA G+C content was 38.2 mol%. On the basis of the phenotypic, phylogenetic and chemotaxonomic data presented, strain P308H10T represents a novel species of the genus Arenibacter, for which the name Arenibacter catalasegens sp. nov. is proposed. The type strain is P308H10T (=GDMCC 1.1230T=KCTC 52983T). An emended description of the genus Arenibacter is also proposed. PMID- 29458461 TI - Characterization of Desulfovibrio salinus sp. nov., a slightly halophilic sulfate reducing bacterium isolated from a saline lake in Tunisia. AB - A novel slightly halophilic sulfate-reducing bacterium, designated strain P1BSRT, was isolated from water of a saline lake in Tunisia. Strain P1BSRT had motile (single polar flagellum), Gram-negative, rod-shaped, non-spore-forming cells, occurring singly or in pairs. Strain P1BSRT grew at temperatures between 15 and 45 degrees C (optimum 40 degrees C), and in a pH range between 6 and 8.5 (optimum pH 6.7). The strain required NaCl for growth (1 % w/v), and tolerated high NaCl concentration (up to 12 % w/v) with an optimum of 3 % (w/v). Sulfate, thiosulfate and sulfite served as terminal electron acceptors, but not elemental sulfur, fumarate, nitrate and nitrite. Strain P1BSRT utilized lactate, pyruvate, formate, d-fructose and glycerol as carbon and energy sources. The main cellular fatty acid was C16 : 0 (50.8 %). The genomic DNA G+C content was 47.7 mol%. Phylogenetic analysis of 16S rRNA gene sequence similarity indicated that strain P1BSRT was affiliated to the genus Desulfovibrio, with the type strains Desulfovibrio salexigens (96.51 %), Desulfovibrio zosterae (95.68 %), Desulfovibrio hydrothermalis (94.81 %) and Desulfovibrio ferrireducens (94.73 %) as its closest phylogenetic relatives. On the basis of genotypic, phenotypic and phylogenetic characteristics, it is proposed to assign strain P1BSRT to a novel species of the genus Desulfovibrio, Desulfovibrio salinus sp. nov. The type strain is P1BSRT (=DSM 101510T=JCM 31065T). PMID- 29458462 TI - Lactobacillus panisapium sp. nov., from honeybee Apis cerana bee bread. AB - A novel facultatively anaerobic, Gram-stain-positive, non-motile, non-spore forming, catalase-negative bacterium of the genus Lactobacillus, designated strain Bb 2-3T, was isolated from bee bread of Apis cerana collected from a hive in Kunming, China. The strain was regular rod-shaped. Optimal growth occurred at 37 degrees C, pH 6.5 with 5.0 g l-1 NaCl. The predominant fatty acids were C18 : 1omega9c, C16 : 0 and C19 : 0 iso. Respiratory quinones were not detected. Seven glycolipids, three lipids, phosphatidylglycerol and diphosphatidylglycerol were detected. The peptidoglycan type A4alpha l-Lys-d-Asp was determined. Strain Bb 2 3T was closely related to Lactobacillus bombicola DSM 28793T, Lactobacillus apis LMG 26964T and Lactobacillus helsingborgensis DSM 26265T, with 97.8, 97.6 and 97.0 % 16S rRNA gene sequence similarity, respectively. A comparison of two housekeeping genes, rpoA and pheS, revealed that strain Bb 2-3T was well separated from the reference strains of species of the genus Lactobacillus. The average nucleotide identity between strain Bb 2-3T and the type strains of closely related species was lower than the 95-96 % threshold value for delineation of genomic prokaryotic species. The G+C content of the genomic DNA of strain Bb 2-3T was 37.4 mol%. On the basis of phenotypic, chemotaxonomic and phylogenetic analyses, strain Bb 2-3T is proposed to represent a novel species of the genus Lactobacillus, for which we propose the name Lactobacillus panisapium sp. nov. The type strain is Bb 2-3T (=DSM 102188T=ACCC 19955T). PMID- 29458463 TI - Raineya orbicola gen. nov., sp. nov. a slightly thermophilic bacterium of the phylum Bacteroidetes and the description of Raineyaceae fam. nov. AB - An isolate, designated SPSPC-11T, with an optimum growth temperature of about 50 degrees C and an optimum pH for growth between 7.5 and 8.0, was recovered from a hot spring in central Portugal. Based on phylogenetic analysis of its 16S rRNA sequence, the new organism is most closely related to the species of the genus Thermonema but with a pairwise sequence similarity of <85 %. The isolate was orange-pigmented, formed non-motile long filaments and rod-shaped cells that stain Gram-negative. The organism was strictly aerobic, oxidase-positive and catalase-positive. The major fatty acids were iso-C15:0, iso-C15 : 0 2-OH and iso C17 : 0 3-OH. The major polar lipids were one aminophospholipid, two aminolipids and three unidentified lipids. Menaquinone 7 was the major respiratory quinone. The DNA G+C content of strain SPSPC-11T was 37.6 mol% (draft genome sequence). The high quality draft genome sequence corroborated many of the phenotypic characteristics of strain SPSPC-11T. Based on genotypic, phylogenetic, physiological and biochemical characterization we describe a new species of a novel genus represented by strain SPSPC-11T (=CECT 9012T=LMG 29233T) for which we propose the name Raineya orbicola gen. nov., sp. nov. We also describe the family Raineyaceae to accommodate this new genus and species. PMID- 29458464 TI - Delineation of a novel subgroup 16SrXIII-J phytoplasma, a 'Candidatus Phytoplasma hispanicum'-related strain, based on computer-simulated RFLP and phylogenetic analysis. AB - Symptoms of fruit phyllody and slow growth, which are suggestive of phytoplasma infection, were observed in strawberry plants cultivated in commercial fields. In order to provide evidence of association of phytoplasma with affected plants, assays for detecting and identifying were performed through computer-simulated restriction fragment length polymorphism (RFLP) and phylogenetic analysis. Total DNA was extracted from symptomatic and asymptomatic samples and used as template in nested PCR primed by the primers P1/Tint followed by R16F2n/16R2. Amplified DNA fragments of 1.2 kb from the 16S rRNA gene revealed the presence of phytoplasma in all symptomatic samples. Molecular detection was confirmed by electron transmission microscopy, which evidenced pleomorphic bodies in the phloem vessels. Nucleotide sequence representative of the strawberry phytoplasma shared 97.2 to 99 % similarity with phytoplasmas currently classified as members of the distinct subgroups within the 16SrXIII group. Similarity coefficient (F) values ranged from 0.70 to 0.92, indicating that strawberry phytoplasma delineates a new strain in addition to 'Candidatus Phytoplasma hispanicum' related strains.

PMID- 29458472 TI - Polyphasic data support the splitting of Aspergillus candidus into two species; proposal of Aspergillus dobrogensis sp. nov. AB - Aspergillus candidus is a species frequently isolated from stored grain, food, indoor environments, soil and occasionally also from clinical material. Recent bioprospecting studies highlighted the potential of using A. candidus and its relatives in various industrial sectors as a result of their significant production of enzymes and bioactive compounds. A high genetic variability was observed among A. candidus isolates originating from various European countries and the USA, that were mostly isolated from indoor environments, caves and clinical material. The A. candidus sensu lato isolates were characterized by DNA sequencing of four genetic loci, and agreement between molecular species delimitation results, morphological characters and exometabolite spectra were studied. Classical phylogenetic methods (maximum likelihood, Bayesian inference) and species delimitation methods based on the multispecies coalescent model supported recognition of up to three species in A. candidus sensu lato. After evaluation of phenotypic data, a broader species concept was adopted, and only one new species, Aspergillus dobrogensis, was proposed. This species is represented by 22 strains originating from seven countries (ex-type strain CCF 4651T=NRRL 62821T=IBT 32697T=CBS 143370T) and its differentiation from A. candidus is relevant for bioprospecting studies because these species have different exometabolite profiles. Evaluation of the antifungal susceptibility of section Candidi members to six antifungals using the reference EUCAST method showed that all species have low minimum inhibitory concentrations for all tested antifungals. These results suggest applicability of a wide spectrum of antifungal agents for treatment of infections caused by species from section Candidi.

The fatty acid profile from whole-cell hydrolysates supported the allocation of the strain to the genus Halomonas. The fatty acids C18 : 1omega7c and C16 : 0 were found as major compounds, followed by the hydroxylated fatty acid C12 : 0 3-OH. The quinone system consisted predominantly of ubiquinone Q-9. The polar lipid profile was composed of the major lipids diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. In the polyamine pattern, spermidine was the predominant compound.

Cell growth was stimulated by yeast extract, peptone, meat extract, a mixture of 20 amino acids, glucose, pyruvate and ribose. When grown on peptone and yeast extract, the main fermentation products were acetic acid, H2 and CO2. The predominant cellular fatty acids were iso-C15 : 0 and iso-C14 : 0 3-OH. Major polar lipids were diphosphatidylglycerol, glycolipids, phospholipids and phosphatidylgycerol. Phylogenetic analysis based on 16S rRNA gene nucleotide sequence analysis placed strain BA2-13T within the order Clostridiales showing closest affiliation with Proteiniborusethanoligenes with 95.9 % sequence identity. Physiological, genotypic and chemotaxonomic differences of strain BA2-13T from P. ethanoligenes support the description of a new species within the genus Proteiniborus for which we suggest the name Proteiniborusindolifex sp. nov. (type strain BA2-13T=DSM 103060T=LMG 29818T). PMID- 29458501 TI - Vibrio fujianensis sp. nov., isolated from aquaculture water. AB - A Gram-stain-negative, facultatively anaerobic strain, designated FJ201301T, was isolated from aquaculture water collected from Fujian province, China. Phylogenetic analysis of 16S rRNA gene sequences indicated that strain FJ201301T belonged to the genus Vibrio, formed a distinct cluster with Vibriocincinnatiensis ATCC 35912T and shared the highest similarity with Vibriosalilacus CGMCC 1.12427T. A 15 bp insertion found in the 16S rRNA gene was a significant marker that distinguished strain FJ201301T from several phylogenetic neighbours (e.g. V. cincinnatiensis). Multilocus sequence analysis of eight genes (ftsZ, gapA, gyrB, mreB, pyrH, recA, rpoA and topA; concatenated 4135 bp sequence) showed that, forming a long and independent phylogenetic branch, strain FJ201301T clustered with V. cincinnatiensis ATCC 35912T, Vibrioinjenensis KCTC 32233T and Vibriometschnikovii CIP 69.14T clearly separated from V. salilacus CGMCC 1.12427T. Furthermore, the highest in silico DNA-DNA hybridization and average nucleotide identity values between strain FJ201301T and the closest related species were 26.3 and 83.1 % with V. cincinnatiensis ATCC 35912T, less than the proposed cutoff levels for species delineation, i.e. 70 and 95 %, respectively. Biochemical, sequence and genomic analysis suggested the designation of strain FJ201301T representing a novel species of the genus Vibrio, for which the name Vibrio fujianensis sp. nov. is proposed. The type strain is FJ201301T (=DSM 104687T=CGMCC 1.16099T). PMID- 29458502 TI - Blastococcus xanthinilyticus sp. nov., isolated from monument. AB - A novel, non-motile, coccoid, Gram-stain-positive actinobacterium, designated BMG 862T, was isolated from a marble sample collected from the Bulla Regia monument, Northern Tunisia. Its taxonomic position was determined using a polyphasic approach. Results from chemotaxonomic analyses showed MK-9(H4), MK-8(H4) and MK 9(H2) as the predominant menaquinones. The major polar lipids comprised diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, glycophosphatidylinositol, hydroxy-phosphatidylethanolamine and three unidentified phospholipids. The fatty acids consisted of significant amounts (>=10 %) of iso-C16 : 0, C17 : 1omega8c, iso-C15 : 0 and C16 : 1omega7c. Phylogenetic analysis on the basis of 16S rRNA gene sequence comparisons showed that strain BMG 862T belongs to the genus Blastococcus, being most closely related to Blastococcus saxobsidens (=DSM 44509T) (99.5 %) and Blastococcus capsensis (=DSM 46835T=CECT 8876T) (99.3 %). The genomic DNA G+C content of the organism was 74.7 mol%. Results of DNA-DNA hybridization and physiological tests allowed differentiation of strain BMG 862T from related species. The strain was also characterized by its ability to hydrolyse xanthine. On the basis of phenotypic and molecular characteristics, strain BMG 862T (=DSM 46842T=CECT 8884T) represents the type strain of a novel species of the genus Blastococcus, for which the name Blastococcus xanthinilyticus sp. nov. is proposed. PMID- 29458503 TI - Georgenia deserti sp. nov., a halotolerant actinobacterium isolated from a desert sample. AB - Strain SYSU D8004T was isolated from a sample collected from an arid area in Saudi Arabia. The isolate was Gram-stain-positive, non-motile, aerobic and non spore-forming. It could grow at 4-45 degrees C, at pH 6.0-10.0 and in the presence of up to 17 % (w/v) NaCl. Pairwise comparison of the 16S rRNA gene sequences indicated that strain SYSU D8004T shared highest sequence similarity with Georgenia halophila YIM 93316T (96.5 %). Menaquinone MK-8(H4) was detected as the respiratory quinone. The polar lipid profile of strain SYSU D8004T consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, two phosphatidylinositol mannosides, two unidentified phospholipids and an unidentified glycolipid. Strain SYSU D8004T contained anteiso-C15 : 0, iso-C15 : 0 and C14 : 0 as the predominant fatty acids (>10 %). Galactose, glucose and rhamnose were detected as whole-cell sugars. Based on analyses of the phenotypic, genotypic and phylogenetic characteristics, it was determined that strain SYSU D8004T could be differentiated from other closely related members of the genus Georgenia. Strain SYSU D8004T is therefore considered to represent a novel species of the genus Georgenia, for which the name Georgenia deserti sp. nov. is proposed. The type strain is SYSU D8004T (=CGMCC 1.15793T=KCTC 39987T). PMID- 29458504 TI - Salinisphaera aquimarina sp. nov., isolated from seawater. AB - A Gram-stain-negative, aerobic, rod-shaped, motile bacterium with a subpolar flagellum, designated strain CCMM005T, was isolated from offshore seawater at Qingdao, China. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain CCMM005T belonged to the genus Salinisphaera and exhibited highest 16S rRNA gene sequence similarity to Salinisphaera dokdonensis CL-ES53T (96.9 %). It showed lower sequence similarities (94.9-96.4 %) with all other representatives of the genus Salinisphaera. Optimal growth occurred in the presence of 4 % (w/v) NaCl, at 30 degrees C and at pH 7.0. The polar lipids of strain CCMM005T consisted of phosphatidylethanolamine, phosphatidylcholine, phosphatidylglycerol, one unidentified phosphoglycolipid and one unidentified phospholipid. The predominant isoprenoid quinone was Q-8. The major fatty acids were C19 : 0cyclo omega8c, C18 : 0 and C18 : 1omega7c. The DNA G+C content of strain CCMM005T was 65.3 mol%. On the basis of data from this polyphasic study, strain CCMM005T is considered to represent a novel species of the genus Salinisphaera, for which the name Salinisphaera aquimarina sp. nov. is proposed. The type strain is CCMM005T (=MCCC 1K03246T=KCTC 52640T). PMID- 29458505 TI - Actinotalea solisilvae sp. nov., isolated from forest soil and emended description of the genus Actinotalea. AB - A Gram-stain-positive, aerobic, non-motile and short-rod-shaped actinobacterium, designated THG-T121T, was isolated from forest soil. Growth occurred at 10-40 degrees C (optimum 28-30 degrees C), at pH 6-8 (optimum 7) and at 0-4 % NaCl (optimum 1 %). Based on 16S rRNA gene sequence analysis, the nearest phylogenetic neighbours of strain THG-T121T were identified as Actinotalea ferrariae KCTC 29134T (97.9 %), Actinotalea fermentans KCTC 3251T (97.3 %), Cellulomonas carbonis KCTC 19824T (97.2 %). 16S rRNA gene sequence similarities among strain THG-T121T and other recognized species were lower than 97.0 %. The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, two phosphatidylinositol mannosides, one unidentified phospholipid, three unidentified glycolipids and one unidentified lipid. The isoprenoid quinone was menaquinone (MK-10(H4)). The major fatty acids were anteiso-C15 : 0, anteiso-C15 : 1 A, C16 : 0, iso-C16 : 0, anteiso-C17 : 0 and iso-C17 : 0. The whole-cell sugars of strain THG-T121T were rhamnose, ribose, mannose and glucose. The peptidoglycan type of strain THG-T121T is A4beta, containing l-Orn-D-Ser-L-Asp. The DNA G+C content of strain THG-T121T was 72.4 mol%. DNA-DNA hybridization values between strain THG-T121T and A. ferrariae KCTC 29134T, A. fermentans KCTC 3251T and C. carbonis KCTC 19824T were 30.2 % (27.3 %, reciprocal analysis), 28.4 %, (17.3 %) and 16.9 %, (9.3 %), respectively. On the basis of the phylogenetic analysis, chemotaxonomic data, physiological characteristics and DNA-DNA hybridization data, strain THG-T121T represents a novel species of the genus Actinotalea, for which the name Actinotaleasolisilvae sp. nov. is proposed. The type strain is THG-T121T (=KACC 19191T=CGMCC 4.7389T). PMID- 29458506 TI - Avoiding 'salami slicing' in publications describing new prokaryotic taxa. PMID- 29458507 TI - Parolsenella catena gen. nov., sp. nov., isolated from human faeces. AB - Strain 2CBEGH3T, which is an obligately anaerobic, non-pigmented, non-spore forming, non-motile, Gram-stain-positive coccobacillus, was isolated from a faecal sample of a healthy Japanese man. The 16S rRNA gene sequence analysis showed that strain 2CBEGH3T represented a member of the family Atopobiaceae and formed a monophyletic cluster with Olsenella uli DSM 7084T (93.6 % sequence similarity), Olsenella umbonata strain lac31T (93.0 %), Olsenella profusa JCM 14553T (92.7 %) and Olsenella scatoligenes strain SK9K4T (92.7 %) as closest neighbours and Atopobium species. The hsp60 gene sequence analysis supported the phylogenetic relationships based on the 16S rRNA gene sequences, with sequence similarity values of 82.1-84.7 % to the four species described above. A unique three-base (one amino acid residue) insertion was found in the alignment regions of the hsp60 gene sequence of strain 2CBEGH3T. The major end products from d glucose were d- and l-lactic acids produced at the ratio of 75 : 25, while four species of the genus Olsenella produced d- and l-lactic acids at ratios of 94-98 : 2-6. The isolate formed characteristic crater-like colonies on Eggerth-Gagnon agar plates. The major cellular fatty acids were C18 : 1omega9c, C18 : 1omega9c dimethyl acetal (DMA) and C16 : 0 DMA. The G+C content of the genomic DNA was 68.4 mol%. On the basis of these data, strain 2CBEGH3T represents a novel species in a novel genus of the family Atopobiaceae, for which the name Parolsenella catena gen. nov., sp. nov. is proposed. The type strain of P. catena is 2CBEGH3T (=JCM 31932T=DSM 105194T). PMID- 29458508 TI - Rolling-circle replication initiation protein of haloarchaeal sphaerolipovirus SNJ1 is homologous to bacterial transposases of the IS91 family insertion sequences. AB - For most archaeal viruses, the mechanisms of genome replication are poorly understood, while the nature and provenance of their replication proteins are usually unknown. Here we show that replication of the circular double-stranded DNA genome of the halophilic Natrinema virus SNJ1, a member of the family Sphaerolipoviridae, is associated with the accumulation of single-stranded replicative intermediates, which is typical of rolling-circle replication. The homologues of RepA, the only enzyme that is indispensable for SNJ1 genome replication, are widespread in archaea and are most closely related to bacterial transposases of the IS91 and ISCR family insertion sequences, as opposed to other viral rolling-circle replication initiation proteins. Our results provide insights into the replication mechanism of archaeal viruses and emphasize the evolutionary connection between viruses and other types of mobile genetic elements. PMID- 29458509 TI - Emended descriptions of the species Sphingomonas adhaesiva Yabuuchi et al. 1990 and Sphingomonas ginsenosidimutans Choi et al. 2011. AB - During the phylogenetic study of the genus Sphingomonas and its closely related genera, we found that there existed errors in the 16S rRNA gene sequence of the type strain of the type species of Sphingomonas adhaesiva (D13722). Data suggested the wrong sequence should be replaced by the sequence under the accession number KY927401. As the new sequence shared 99.6 % 16S rRNA gene sequence similarity with that of Sphingomonas ginsenosidimutans, the relationship between these two species was reevaluated in the present study. Analyses, based on the whole genome sequences, phenotypic characteristics and fatty acid profiles clearly show that S. adhaesiva and Sphingomonas ginsenosidimutans are two distinct species of the genus Sphingomonas. Considering the errors in the original descriptions of S. adhaesiva and S. ginsenosidimutans, we have emended the descriptions of the two species. PMID- 29458510 TI - Influence of Ambient Air Pollution on Television Use among Residents in Shanghai, China. AB - OBJECTIVES: We examined the impact of ambient air pollution on television use among residents in Shanghai, China. METHODS: Device-measured daily average duration of television use from January 2014 to December 2016 was obtained from a random sample of 300 households, and was matched to air pollution and weather data. We used an autoregressive moving-average model to estimate the association between air quality index (AQI) and television use. RESULTS: There was a negative non-linear relationship between air pollution level and television use. Compared to the days when air quality was good (0<=AQI<=50), days with fair air quality (50150) were associated with a reduction in daily average television use by 2.9 (p = .002), 4.6 (p < .001), and 1.9 (p = .369) minutes, respectively. Television use decreased with daytime temperature but increased on weekend days, holidays, and rainy days. CONCLUSIONS: Modest but not more severe air pollution was associated with reduced television use. People might mitigate the detrimental impact of air pollution by engaging in other indoor activities and/or sleeping. PMID- 29458511 TI - Variability in Intensity Related to Increased Overall Bout Intensity. AB - OBJECTIVE: We examined the relationship between variability in self-regulated exercise intensity and overall intensity during acute exercise. METHODS: Overall, 32 participants (age; 20+/-4y, body mass index (BMI) 24.1+/-3.6 kg/m2) completed a 30-minute self-regulated treadmill exercise bout. Participants were blinded to treadmill settings and adjusted speed and incline every 5-minutes as desired. RESULTS: Variability in exercise intensity (metabolic equivalent standard deviation (METSD)) was positively correlated with (r = .567, p = .001) and explained a significant portion of the overall exercise intensity (beta = .574, t = 3.713, p = .001). When accounting for physiological variables, METSD (beta = .381, t = 2.242, p = .034) and VO2peak (beta = .575, t = 2.864, p = .008) predicted overall intensity. When controlling for physiological and psychological variables, in addition to METSD (beta = .388), tolerance for exercise intensity (beta = 3.124) became a significant predictor of overall bout intensity (p < .05). CONCLUSIONS: In-task variability in exercise intensity was posi- tively related to the average intensity of the bout. Future studies should explore the utility of explicitly encouraging individuals to incorporate intra-bout variety for increasing the exercise dose while maintaining a degree of autonomy. PMID- 29458512 TI - Patterns and Trends of Hookah Use among New Jersey Youth: New Jersey Youth Tobacco Survey 2008-2014. AB - OBJECTIVES: In this study, the aim was to document trends of ever, past 30-day, and frequent (use on > 10 days/month) hookah use among New Jersey (NJ) high school students. METHODS: Data were analyzed from the 2008-2014 waves of the NJ Youth Tobacco Survey, a biennial survey of public high school students in grades 9-12 with a mean age of 15 years. Multivariable logistic regressions assessed trends and correlates of hookah use. Descriptive statistics were used to summarize the use of cigarettes, electronic cigarettes, and other tobacco products (including cigars, smokeless tobacco, and bidis). RESULTS: In 2014, past 30-day hookah use (11.8%) was as high as e-cigarette use (12.1%) and higher than other tobacco products. The adjusted odds of ever, past 30-day, and frequent hookah use were significantly higher in 2014 than 2008. Past 30-day hookah use was more common among users of other tobacco products. CONCLUSIONS: Effective strategies have been used in cigarette tobacco control, and cigarette consumption has decreased as a result. Similar strategies should be employed to encompass emerging tobacco products, with necessary modifications to reduce the prevalence of all tobacco use among youth. PMID- 29458513 TI - Adapting a Skin Cancer Prevention Intervention for Multiethnic Adolescents. AB - OBJECTIVE: We tested the effectiveness of a school-based skin cancer prevention intervention entitled "SunSafe in the Middle School Years" adapted for multiethnic high school students. METHODS: In Hawai'i, 208 10th graders (51.6% Asian, 30.4% Native Hawaiian/Pacific Islander, 8.4% white, 3.5% Hispanic, 2.7% black) participated. Changes in sun protection knowledge, attitudes, and self reported behaviors were measured using a standardized 18-item survey. The Systematic Observation of Sun Protection Factors (SOSPF) instrument assessed aggregate sun protection behaviors. RESULTS: At posttest, improvements were found in 13 of 18 survey items (p < .05), and retained in 10 items at 12-months following baseline assessments; sun-protection attitudes and intended tanning behavior did not show improvement. Six observers using SOSPF reliably measured students' sun protection behaviors at school including use of hats, sunglasses, long sleeves, lower body coverage, and shade (ICC > .77). CONCLUSIONS: We uncovered a lack of knowledge about UVR exposure, tanning, and lifetime skin cancer risk among multiethnic high school students. We found that students' tanning attitudes may be influenced by self-perceptions regarding their own complexion, but were willing to modify their sun protection behaviors once informed about skin cancer risk. PMID- 29458514 TI - Caregiver Daily Experiences Associated with Child Asthma Symptoms. AB - OBJECTIVE: In this study, we used ecological momentary assessment (EMA) delivered via smart- phones to determine how the daily experiences (comfort in neighborhood, ability to manage child's asthma, positive/negative affect) of 59 caregivers (90% African-American/black) living in an urban setting are associated with asthma symptoms in children ages 7-12 years (M = 9.56 years). METHODS: Caregivers and their children with asthma completed a baseline research ses- sion, followed by 14 days of EMA surveys completed on smartphones. EMA enables researchers to examine within-person processes while preserving the ecological validity of the data and re- ducing retrospective recall bias. RESULTS: On days when caregivers reported more child asthma symptoms, they also reported feeling less comfortable in their neighborhoods and less able to control their child's asthma at home. Baseline reports of caregiver quality of life were also associ- ated with child asthma symptoms. CONCLUSIONS: Findings highlight the need for researchers and clinicians to recognize that both asthma (ie, ability to control asthma) and non-asthma related factors (ie, factors related to neighborhoods) may be associated with caregivers' perceptions of their children's asthma symptoms. Perceptions of child symptoms have important consequences for daily asthma care, including decisions related to healthcare utilization. PMID- 29458515 TI - A Pilot Feasibility Study to Improve Food Parenting Practices. AB - OBJECTIVES: We examined the feasibility and acceptability of a novel home-based intervention to improve the food parenting practices of low-income mothers with preschool-aged children. METHODS: Mother-child dyads (N = 15) were recruited from WIC in southern Rhode Island. A non-experimental, pretest-posttest design was used to assess changes in maternal food parenting practices. Dyads participated in 3 home-based sessions that included baseline measures and an evening meal video recording at session 1, a motivational interviewing (MI) intervention that included feedback on the evening meal video recording at session 2, and a satisfaction ques- tionnaire at session 3. Pretest-posttest measures included 5 subscales of the Comprehensive Feeding Practices Questionnaire. RESULTS: Fifteen mother-child dyads (mothers: 32.3, SD = 4.6 years, 86.7% white; children: 3.2, SD = 0.9 years, male = 73.3%, 66.7% white) completed the study. Mothers reported improvements in food parenting practices following the home-based MI intervention. Overall, 93% of mothers 'strongly agreed' that it was worth their effort to participate in the study. CONCLUSIONS: A home-based MI intervention may be an effective strategy for improving maternal food parenting practices in low income populations. Most mothers found that watching themselves was informative and applicable to their own lives. PMID- 29458516 TI - Chronic Disease Risk Typologies among Young Adults in Community College. AB - OBJECTIVES: To address chronic disease risk holistically from a behavioral perspective, insights are needed to refine understanding of the covariance of key health behaviors. This study aims to identify distinct typologies of young adults based on 4 modifiable risk factors of chronic disease using a latent class analysis approach, and to describe patterns of class membership based on demographic characteristics, living arrangements, and weight. METHODS: Overall, 441 young adults aged 18-35 attending community colleges in the Minnesota Twin Cities area completed a baseline questionnaire for the Choosing Healthy Options in College Environments and Settings study, a RCT. Behavioral items were used to create indicators for latent classes, and individuals were classified using maximum-probability assignment. RESULTS: Three latent classes were identified: 'active, binge-drinkers with a healthy dietary intake' (13.1%); 'non-active, moderate-smokers and non-drinkers with poor dietary intake' (38.2%); 'moderately active, non-smokers and non-drinkers with moderately healthy dietary intake' (48.7%). Classes exhibited unique demographic and weight-related profiles. CONCLUSIONS: This study may contribute to the literature on health behaviors among young adults and provides evidence that there are weight and age differences among subgroups. Understanding how behaviors cluster is important for identifying groups for targeted interventions in community colleges. PMID- 29458517 TI - Effects of Large Cigarette Warning Labels on Smokers' Expected Longevity. AB - OBJECTIVES: Smokers underestimate the health risks of smoking and overestimate their expected longevity. Warning labels on cigarette packs might help correct these misperceptions. METHODS: We carried out an online study with 1200 smokers (18-62 years old), randomized to 3 conditions: text warning labels, pictorial warning labels, and a control group (water bottle labels). Warning labels were based on those proposed by the US Food and Drug Administration in 2010. Participants in each condition saw 4 randomly selected labels and rated their expected longevity and chances of surviving to age 75 after exposure. Analyses of covariance controlled for cigarettes per day and self-rated health. RESULTS: Compared to control, both text and pictorial warnings reduced participants' expected longevity (text: mean = 76.8 years, pictorial: 77.3, control 79.4) and their estimated chances of living to 75 (text: 62.0%, pictorial: 63.0%, control 66.5%). The contrast between text and pictorial labels combined and control showed significantly reduced expected longevity (p = .011) and chances of living to 75 (p = .004). Differences between text and pictorial conditions were not statistically significant. CONCLUSIONS: Large text or pictorial warnings on cigarette packs might help smokers develop a more accurate understanding of the effects of smoking on their longevity. PMID- 29458518 TI - Perceived Stress Predicts Lower Physical Activity in African-American Boys, but not Girls. AB - OBJECTIVES: The purpose of this study was to examine cross-sectional relationships of psychological stress, stress coping, and minutes of moderate-to vigorous physical activity (MVPA) in Amer- ican-American (AA) boys and girls. METHODS: A community-based sample of 139 AA adolescents (mean age 14.7 years; SD = 1.8 years; 64.7% girls; 30% obese) from Washtenaw County, Michigan was included in this analysis. Psychological stress was assessed using the Daily Stress Inventory and the Perceived Stress Scale. Coping strategies were evaluated using the Schoolager's Coping Strategies questionnaire. Physical activity was measured objectively via accelerometry. RESULTS: Compared to boys, girls participated in approximately 13 fewer minutes of MVPA (p < .001) per day and reported significantly higher levels of daily stress (p = .03) and perceived stress (p < .001). In addition, girls reported using a greater number of coping strategies (p = .01) at a greater frequency (p = .04) compared to boys. However, perceived stress significantly predicted lower levels of MVPA (p = .03) in boys only. CONCLUSIONS: There are important gender differences in how AA girls perceive, experience, and cope with stress compared to AA boys. Although AA girls reported higher levels of stress and employed more coping strategies, perceived stress was associated with physical inactivity in AA boys, but not girls. Additional research is warranted to better understand the influence of stress on the choice to be physically active in AA youth. PMID- 29458519 TI - Intrapersonal Factors of Male and Female Adolescent Fruit and Vegetable Intake. AB - OBJECTIVES: In this study, we examined the role of socio-demographic (race/ethnicity, sex, grade, nativity, literacy, body mass index) and individual level (normative beliefs, knowledge, perceived barriers, food preference, self efficacy) factors on US adolescent fruit and vegetable consumption. METHODS: We conducted hierarchical multiple regression analysis to determine the influence of factors on adolescent fruit and vegetable consumption in a nationally represen- tative sample of 795 adolescents from the National Cancer Institute's 2014 Family Life, Activity, Sun, Health, and Eating (FLASHE) study. RESULTS: Socio demographic variables explained little variance (1.7%) whereas individual-level factors explained approximately 29% of the variance in adolescent fruit and vegetable consumption. Statistically significant (p < .001) predictors of adolescent fruit and vegetable consumption were food preference (beta = .253), self-efficacy (beta = .184), perceived barriers (beta = -.139), and normative beliefs (beta = .134). After controlling for sex, food preference and normative beliefs were stronger predictors of male, and perceived barriers was a stronger predictor of female, adolescent fruit and vegetable consumption. CONCLUSIONS: Understanding the predictive strength and sex-specific differences of intrapersonal variables on male and female adolescent fruit and vegetable consumption informs health promotion efforts to increase intake to recommended amounts. PMID- 29458521 TI - Two novel thermally resistant endolysins encoded by pseudo T-even bacteriophages RB43 and RB49. AB - Identification and cloning of genes as well as biochemical characterization of the gene products were carried out for two novel endolysins of pseudo T-even lytic bacteriophages RB43 and RB49, which represent different myovirus groups of the subfamily Tevenvirinae. Genes RB43ORF159c and RB49r102 were cloned in E. coli cells, and their products were purified to electrophoretic homogeneity with an up to 80 % yield of total activity. In respect to substrate specificity, both enzymes were found to be lytic l-alanoyl-d-glutamate peptidases belonging to the M15 family. The pH optimum functioning of both endolysins was within the range 7.0-9.0, whereas the optimal values of ionic strength were different for the two proteins (25 mM vs 100 mM for the RB43 and RB49 endolysins respectively). Both peptidases were thermally resistant, with the RB43 endolysin being more stable (it restored 81 % of enzyme activity and 96 % of secondary structure after a 10 min heating at 90 degrees C) than its RB49 counterpart (27 and 77% respectively). The possible origin of genes of lytic l-alanoyl-d-glutamate peptidases of myoviruses as a result of horizontal transfer in the variable parts of genomes between unrelated phages having a common host is discussed. PMID- 29458520 TI - Social Media Use and Depression and Anxiety Symptoms: A Cluster Analysis. AB - OBJECTIVES: Individuals use social media with varying quantity, emotional, and behavioral at- tachment that may have differential associations with mental health outcomes. In this study, we sought to identify distinct patterns of social media use (SMU) and to assess associations between those patterns and depression and anxiety symptoms. METHODS: In October 2014, a nationally-representative sample of 1730 US adults ages 19 to 32 completed an online survey. Cluster analysis was used to identify patterns of SMU. Depression and anxiety were measured using respective 4-item Patient-Reported Outcome Measurement Information System (PROMIS) scales. Multivariable logistic regression models were used to assess associations between clus- ter membership and depression and anxiety. RESULTS: Cluster analysis yielded a 5-cluster solu- tion. Participants were characterized as "Wired," "Connected," "Diffuse Dabblers," "Concentrated Dabblers," and "Unplugged." Membership in 2 clusters - "Wired" and "Connected" - increased the odds of elevated depression and anxiety symptoms (AOR = 2.7, 95% CI = 1.5-4.7; AOR = 3.7, 95% CI = 2.1-6.5, respectively, and AOR = 2.0, 95% CI = 1.3 3.2; AOR = 2.0, 95% CI = 1.3-3.1, respectively). CONCLUSIONS: SMU pattern characterization of a large population suggests 2 pat- terns are associated with risk for depression and anxiety. Developing educational interventions that address use patterns rather than single aspects of SMU (eg, quantity) would likely be useful. PMID- 29458522 TI - Paenibacillus mobilis sp. nov., a Gram-stain-negative bacterium isolated from soil. AB - A novel Gram-stain-negative bacterium, designated strain S8T, was isolated from a soil sample obtained in Gyeonggi Province, Republic of Korea. Cells of strain S8T were endospore-forming, motile by means of peritrichous flagella, and rod-shaped. S8T colonies were round, convex, wavy and white. Strain S8T grew optimally at 37 degrees C, pH 6-8, and up to 2.0 % (w/v) NaCl. Based on 16S rRNA gene sequence similarity, strain S8T was affiliated with the genus Paenibacillus in the family Paenibacillaceae and was most closely related to Paenibacillus yonginensis DCY84T and Paenibacillus physcomitrellae XBT (98.8 and 97.1 % sequence similarity). The DNA G+C content of the novel strain was 53.1+/-0.3 mol%. Strain S8T contained diphosphatidylglycerol, phosphatidylglycerol, two phospholipids, four aminophospholipids, an aminolipid and three unidentified lipids. The major fatty acid was anteiso-branched C15 : 0. The quinone was menaquinone MK-7. The peptidoglycan of strain S8T contained meso-diaminopimelic acid. The DNA-DNA hybridization values of strain S8T with P. yonginensis KCTC 33428T and P. physcomitrellae DSM 29851T were 44 % and 32 %, respectively. Data from the DNA DNA hybridization, biochemical, phylogenetic and physiological analyses indicate that strain S8T (=KCTC 33848T=JCM 31672T) represents a novel species of the genus Paenibacillus, for which the name Paenibacillus mobilis sp. nov. is proposed. PMID- 29458523 TI - hnRNP G prevents inclusion on the HPV16 L1 mRNAs of the central exon between splice sites SA3358 and SD3632. AB - HPV16 late L1 mRNAs encode a short central exon that is located between HPV16 3' splice site SA3358 and HPV16 5'-splice site SD3632. While SA3358 is used to produce both HPV16 early mRNAs encoding the E6 and E7 oncogenes, and late mRNAs encoding E4, L1 and L2, SD3632 is used exclusively to produce late L1 mRNA. We have previously identified an 8-nucleotide regulatory RNA element that is required for inclusion of the exon between SA3358 and SD3632 to produce L1 mRNAs at the expense of mRNAs polyadenylated at the HPV16 early polyadenylation signal pAE. Here we show that this HPV16 8-nucleotide splicing enhancer interacts with hnRNP G. Binding of hnRNP G to this element prevents inclusion of the exon between SA3358 and SD3632 on the HPV16 late L1 mRNAs. We concluded that hnRNP G has a splicing inhibitory role and that hnRNP G can control HPV16 mRNA splicing.

AB - Ducks, the reservoir host, are generally permissive to influenza A virus infection without disease symptoms. This natural ecology was upset by the emergence of H5N1 strains, which can kill ducks. To better understand host-virus interactions in the reservoir host, and influenza strain-specific molecular contributions to virulence, we infected White Pekin ducks with three similar H5N1 viruses, with known differences in pathogenicity and replication rate. We quantified viral replication and innate immune gene activation by qPCR, in lung and spleen tissues, isolated on each of the first 3 days of infection. The three viruses replicated well, as measured by accumulation of matrix gene transcript, and viral load declined over time in the spleen. The ducks produced rapid, but temporally limited, IFN and cytokine responses, peaking on the first day post infection. IFN and proinflammatory cytokine gene induction were greater in response to infection with the more lethal viruses, compared to an attenuated strain. We conclude that a well-regulated IFN response, with the ability to overcome early viral immune inhibition, without hyperinflammation, contributes to the ability of ducks to survive H5N1 influenza replication in their airways, and yet clear systemic infection and limit disease. PMID- 29458525 TI - Major histocompatibility complex I of swine respiratory cells presents conserved regions of influenza proteins. AB - Influenza A virus in swine (IAV-S) is a prevalent respiratory pathogen in pigs that has deleterious consequences to animal and human health. Pigs represent an important reservoir for influenza and potential mixing vessel for novel gene reassortments. Despite the central role of pigs in recent influenza outbreaks, much remains unknown about the impact of swine immunity on IAV-S transmission, pathogenesis, and evolution. An incomplete understanding of interactions between the porcine immune system and IAV-S has hindered development of new diagnostic tools and vaccines. In order to address this gap in knowledge, we identified swine leukocyte antigen (SLA) restricted IAV-S peptides presented by porcine airway epithelial cells using an immunoproteomics approach. The majority of MHC associated peptides belonged to matrix 1, nucleoprotein and nonstructural 1 proteins. Future investigation of the potential cross-reactive nature of these peptides is needed to confirm antigen recognition by cytotoxic T lymphocytes and their utility as vaccine candidates. PMID- 29458526 TI - Identification of a novel linear B-cell epitope as a vaccine candidate in the N2N3 subdomain of Staphylococcus aureus fibronectin-binding protein A. AB - PURPOSE: To explore an epitope-based vaccine against Staphylococcus aureus, we screened the epitopes in the N2N3 subdomain of fibronectin-binding protein A (FnBPA) as a surface component of S. aureus. METHODOLOGY: We expressed N2N3 proteins and prepared monoclonal antibodies (mAbs) against N2N3 by the hybridoma technique, before screening the B-cell epitopes in N2N3 using a phage-displayed random 12-mer peptide library with these mAbs against N2N3. Finally, we analysed the characters of the screened epitopes using immunofluorescence and an S. aureus infection assay. RESULTS: In this paper, we identified a linear B-cell epitope in N2N3 through screening a phage-displayed peptide library with a 3C3 mAb against the N2N3. The 3C3 mAb recognized the 159IETFNKANNRFSH171 sequence of the N2N3 subdomain. Subsequently, site-directed mutagenic analysis demonstrated that residues F162, K164, N167, R168 and F169 formed the core of 159IETFNKANNRFSH171, and this core motif was the minimal determinant of the B-cell epitope recognized by the 3C3 mAb. The epitope 159IETFNKANNRFSH171 showed high homology among different S. aureus strains. Moreover, this epitope was exposed on the surface of the S. aureus by using an enzyme-linked immunosorbent assay (ELISA) assay and an indirect immunofluorescence assay. As expected, the epitope peptide evoked a protective immune response against S. aureus infection in immunized mice. CONCLUSION: We identified a novel linear B-cell epitope, 159IETFNKANNRFSH171, in the N2N3 subdomain of S. aureus fibronectin-binding protein A that is recognized by 3C3 mAb, which will contribute to the further study of an epitope-based vaccine candidate against S. aureus. PMID- 29458528 TI - A point-mutation of Coleus blumei viroid 1 switches the potential to transmit through seed. AB - Viroids are highly structured, single-stranded, non-protein-coding circular RNA pathogens that replicate, spread and elicit severe to mild disease symptoms in sensitive host species. The functions of viroids are thought to be due to a molecular element (or elements) embedded within the small RNA molecule that recruits the host factors responsible for transcription, RNA transportation and regulation of gene expression. Coleus blumei viroid 1 (CbVd-1) is distributed worldwide and is known for its characteristic property of having an extremely high frequency of seed transmission. During our analysis of CbVd-1 seed transmission, two variants, CbVd-1/25A and CbVd-1/25UU, were shown to have distinct seed-transmission frequencies: 30 and 0 %, respectively. Seven infectious dimeric forms of CbVd-1 cDNA clones were created based on the sequences of CbVd-1/25A,CbVd-1/25UU and an additional five variants with unique loop structures in other portion(s) of the molecule, and in vitro transcripts were inoculated into viroid-free coleus seedlings. All seven CbVd-1 variants showed infectivity. Nucleotide sequence analysis of the progeny revealed that four of the five additional mutants changed to either CbVd-1/25A or CbVd-1/25UU, while, CbVd-1/25A, CbVd-1/25UU and one of the five additional mutants (CbVd-1/I2) replicated stably. As expected, CbVd-1/25A and CbVd-1/I2 were transmitted through seeds, but CbVd-1/25UU was not. CbVd-1/25A and CbVd-1/I2 shared the same nucleotide at position 25 in loop five but are different from CbVd-1/25UU at that position. Therefore, nucleotide 25 in loop five was identified as a determinant for seed transmission of CbVd-1. PMID- 29458527 TI - Terrimonas soli sp. nov., isolated from farmland soil. AB - A Gram-staining-negative, aerobic, non-motile and rod-shaped bacterium that produced yellow viscous colonies, designated FL-8T, was isolated from farmland soil in Chuzhou, Anhui province, PR China. 16S rRNA gene sequence similarities between strain FL-8T and the type strains of species of the genus Terrimonas with validly published names ranged from 94.6 to 96.1 %. Strain FL-8T contained iso C15 : 1 G, iso-C15 : 0 and iso-C17 : 0 3-OH as the predominant fatty acids. The predominant polar lipid of strain FL-8T was phosphatidylethanolamine. The sole respiratory quinone of strain FL-8T was MK-7 and the DNA G+C content was 44.8 mol%. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain FL 8T is considered to represent a novel species of the genus Terrimonas, for which the name Terrimonassoli sp. nov. is proposed. The type strain is FL-8T (=CCTCC AB 2017059T=JCM 32095T). PMID- 29458529 TI - Both murine host and inoculum modulate expression of experimental variant Creutzfeldt-Jakob disease. AB - Transmissible spongiform encephalopathies (TSEs) are infections that are experimentally transmissible to laboratory animals. TSE agents (prions) can be serially passaged in the same animal species. The susceptibility of mice to infection with specific TSE agents can be unpredictable and must be established empirically. We challenged wild-type C57BL/6 and RIIIS/J mice and transgenic mice overexpressing bovine prion protein (TgBo110) with a human brain infected with variant Creutzfeldt-Jakob disease (vCJD) agent and pooled brains of macaques experimentally infected with human vCJD agent (first-passage macaque vCJD). The human vCJD brain yielded a wide range of infectivity titres in different mouse models; TgBo110 mice were the most sensitive. In contrast, infectivity titres of macaque vCJD brain were similar in all three murine models. The brains of RIIIS/J mice infected with both human and macaque vCJD had mild or no vacuolation, while infected C57BL/6 and TgBo110 mice had spongiform degeneration with vacuolation. Abnormal prion protein (PrPTSE) extracted from the brains of vCJD-infected TgBo110 mice displayed different glycosylation profiles and had greater resistance to denaturation by guanidine hydrochloride than PrPTSE from infected wild-type mice or from either inoculum. Those histopathological features of TSE and physical properties of PrPTSE in mice with experimental vCJD were intrinsic to the host, even though we also observed differences between wild-type mice infected with either agent, suggesting a modulatory effect of the inoculum. This study compared three widely used mouse models infected with two different vCJD inocula. The results show that the host plays a major role in manifestations of experimental TSEs. PMID- 29458530 TI - SUMOylation of IE2p86 is required for efficient autorepression of the human cytomegalovirus major immediate-early promoter. AB - The human cytomegalovirus (HCMV) IE2p86 protein is pivotal for coordinated regulation of viral gene expression. Besides functioning as a promiscuous transactivator, IE2p86 is also known to negatively regulate its own transcription. This occurs via direct binding of IE2p86 to a 14-bp palindromic DNA element located between the TATA box and the transcription start site of the major immediate-early promoter (MIEP), which is referred to as the cis repression signal (CRS). However, the exact mechanism of IE2p86-based autorepression is still unclear. By testing a series of IE2p86 mutants in transient expression assays, we found that not only did a DNA binding-deficient mutant of IE2p86 fail to repress the MIEP, but SUMOylation-negative mutants also failed to repress it. This finding was further supported by infection studies with primary fibroblasts harbouring a MIEP-driven transgene as a reporter. Here, we observed that a recombinant HCMV expressing SUMOylation-negative IE2p86 was defective in transgene downregulation, in contrast to wild-type HCMV. Interestingly, however, a double-mutant virus in which both the SUMO acceptor sites and the SUMO interaction motif (SIM) of IE2p86 were inactivated regained the ability to silence the MIEP. This correlated with increased expression levels of the IE2 isoforms IE2p40 and IE2p60, suggesting that these late proteins may contribute to MIEP suppression, thus compensating for the loss of IE2p86 SUMOylation. In summary, our results show that autorepression of the MIEP is not only regulated by late isoforms of IE2, but also depends on posttranslational SUMO modification, revealing a novel mechanism to fine-tune the expression of this important viral gene region. PMID- 29458531 TI - Adhaeribacter swui sp. nov., isolated from wet mud. AB - Strain 17mud1-7T, a pink, aerobic, catalase-positive, oxidase-positive and Gram reaction-negative bacterium, was isolated from wet mud. The isolate grew aerobically at 18-37 degrees C (optimum 28 degrees C), at pH 6.0-8.0 (optimum pH 7.0) and in the presence of 0-1 % (w/v) NaCl (optimum 0 % NaCl). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain 17mud1-7T belonged to the genus Adhaeribacter with highest sequence similarity of 96.4 % to Adhaeribacter aerophilus 6424S-25T. The strain showed the typical chemotaxonomic characteristics of the genus Adhaeribacter, with the presence of menaquinone MK-7 as the respiratory quinone, and summed feature 4 (composed of iso-C17 : 1 I/anteiso-C17 : 1 B), iso-C15 : 0 and C16 : 1omega5c as the major fatty acids are. The polar lipid profile contained two aminophosphoglycolipids, two glycolipids and three unidentified lipids. The DNA G+C content of strain 17mud1 7T was 45.9 mol%. Strain 17mud1-7T should thus be classified as representing a novel species in the genus Adhaeribacter, for which the name Adhaeribacter swui sp. nov. is proposed. The type strain is 17mud1-7T (=KCTC 52873T=NBRC 112824T). PMID- 29458532 TI - ICTV Virus Taxonomy Profile: Ampullaviridae. AB - The family Ampullaviridae includes viruses with linear dsDNA genomes that replicate in hyperthermophilic archaea from the genus Acidianus. The virions have a unique champagne bottle-shaped morphology and consist of a nucleoprotein filament condensed into a cone-shaped core, which is encased by an envelope, with the base of the 'bottle' decorated with a ring of 20 filaments. Genome replication is presumably carried out by the virus-encoded protein-primed family B DNA polymerase. The bottle-shaped morphology is unprecedented among viruses of bacteria and eukaryotes and represents a group of archaea-specific virion morphotypes. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the taxonomy of the Ampullaviridae, which is available at www.ictv.global/report/ampullaviridae. PMID- 29458533 TI - A clash of ideas - the varying uses of the 'species' term in virology and their utility for classifying viruses in metagenomic datasets. AB - Species definitions of viruses are frequently descriptive, with assignments often being based on their disease manifestations, host range, geographical distribution and transmission routes. This method of categorizing viruses has recently been challenged by technology advances, such as high-throughput sequencing. These have dramatically increased knowledge of viral diversity in the wider environment that dwarfs the current catalogue of viruses classified by the International Committee for the Taxonomy of Viruses (ICTV). However, because such viruses are known only from their sequences without phenotypic information, it is unclear how they might be classified consistently with much of the existing taxonomy framework. This difficulty exposes deeper incompatibilities in how species are conceptualized. The original species assignments based on disease or other biological attributes were primarily descriptive, similar to principles used elsewhere in biology for species taxonomies. In contrast, purely sequence based classifications rely on genetic metrics such as divergence thresholds that include or exclude viruses in individual species categories. These different approaches bring different preconceptions about the nature of a virus species, the former being more easily conceptualized as a category with a part/whole relationship of individuals and species, while species defined by divergence thresholds or other genetic metrics are essentially logically defined groups with specific inclusion and exclusion criteria. While descriptive species definitions match our intuitive division of viruses into natural kinds, rules-based genetic classifications are required for viruses known from sequence alone, whose incorporation into the ICTV taxonomy is essential if it is to represent the true diversity of viruses in nature. PMID- 29458534 TI - Specific transcriptional and post-transcriptional regulation of the major immediate early ICP4 gene of GaHV-2 during the lytic, latent and reactivation phases. AB - Transcriptional and post-transcriptional mechanisms are involved in the switch between the lytic, latent and reactivation phases of the viral cycle in herpesviruses. During the productive phases, herpesvirus gene expression is characterized by a temporally regulated cascade of immediate early (IE), early (E) and late (L) genes. In alphaherpesviruses, the major product of the IE ICP4 gene is a transcriptional regulator that initiates the cascade of gene expression that is essential for viral replication. In this study, we redefine the infected cell protein 4 (ICP4) gene of the oncogenic Marek's disease virus (MDV or gallid herpesvirus 2) as a 9438 nt gene ended with four alternative poly(A) signals and controlled by two alternative promoters containing essentially ubiquitous functional response elements (GC, TATA and CCAAT boxes). The distal promoter is associated with ICP4 gene expression during the lytic and the latent phases, whereas the proximal promoter is associated with the expression of this gene during the reactivation phase. Both promoters are regulated by DNA methylation during the viral cycle and are hypermethylated during latency. Transcript analyses showed ICP4 to consist of three exons and two introns, the alternative splicing of which is associated with five predicted nested ICP4ORFs. We show that the ICP4 gene is highly and specifically regulated by transcriptional and post transcriptional mechanisms during the three phases of the GaHV-2 viral cycle, with a clear difference in expression between the lytic phase and reactivation from latency in our model. PMID- 29458535 TI - Isolation, characterization and genomic analysis of a novel lytic bacteriophage vB_SsoS-ISF002 infecting Shigella sonnei and Shigella flexneri. AB - PURPOSE: Shigellosis is one of the most important food-borne and water-borne diseases worldwide. Although antibiotics are considered as efficient agents for shigellosis treatment, improper use of these has led to the emergence of antibiotic-resistant Shigella spp. Therefore, finding a new strategy as alternative treatment seems necessary. METHODOLOGY: Different samples from a wastewater treatment plant were used to isolate Shigella spp. specific phages. Physiological properties were determined, and genomic analysis was also carried out. RESULTS: A virulent Siphoviridae bacteriophage, vB_SsoS-ISF002, was isolated from urban wastewater in Iran and showed infectivity to different isolates of both Shigella sonnei and Shigella flexneri. vB_SsoS-ISF002 was stable at different pH values and temperatures. It had a short latent period (15 min), a large burst size (76+/-9 p.f.u. cell-1) and appropriate lytic activity especially at high MOI. Its genome (dsDNA) was 50 564 bp with 45.53 % GC content and 76 predicted open reading frames. According to comparative genomic analysis and phylogenic tree construction, vB_SsoS-ISF002 was considered as a member of the T1virus genus. CONCLUSION: These results indicated that vB_SsoS-ISF002 is a novel virulent T1virus phage and may have potential as an alternative treatment for shigellosis. PMID- 29458536 TI - Phyllobacterium salinisoli sp. nov., isolated from a Lotus lancerottensis root nodule in saline soil from Lanzarote. AB - A Gram-negative rod, designated strain LLAN61T, was isolated from a root nodule of Lotus lancerottensis growing in a saline soil sample from Lanzarote (Canary Islands). The strain grew optimally at 0.5 % (w/v) NaCl and tolerated up to 3.5 %. The 16S rRNA gene sequence analysis showed that strain LLAN61T belonged to genus Phyllobacterium and that Phyllobacteriumleguminum ORS 1419T and Phyllobacteriummyrsinacearum IAM 13584T are the closest related species with 97.93 and 97.86% similarity values, respectively. In the atpD phylogeny, P. leguminum ORS 1419T and P. myrsinacearum ATCC 43591T, sharing similarities of 87.6 and 85.8% respectively, were also the closest species to strain LLAN61T. DNA DNA hybridization showed an average value of 21 % between strain LLAN61T and P. leguminum LMG 22833T, and 6 % with P. myrsinacearum ATCC 43590T. The predominant fatty acids were C19 : 0 cyclo omega8c and C18 : 1omega6c/C18 : 1omega7c (summed feature 8). The DNA G+C content was 58.0 mol%. Strain LLAN61T differed from its closest relatives in some culture conditions and in assimilation of several carbon sources. Based upon the results of phylogeny, DNA-DNA hybridization, phenotypic tests and fatty acid analysis, this strain should be classified as a novel species of Phyllobacterium for which the name Phyllobacterium salinisoli sp. nov. is proposed (type strain LLAN61T=LMG 30173T = CECT 9417T). PMID- 29458537 TI - Desulfothermobacter acidiphilus gen. nov., sp. nov., a thermoacidophilic sulfate reducing bacterium isolated from a terrestrial hot spring. AB - An anaerobic sulfate-reducing micro-organism, strain 3408-1T, was isolated from a terrestrial hot spring in Kamchatka peninsula (Russia). The cells were spore forming rods with a Gram-positive type of cell wall. The new isolate was a moderately thermoacidophilic anaerobe able to grow either by sulfate or thiosulfate respiration with H2 or formate as substrates, or by fermenting yeast extract, maltose, sucrose, glucose and pyruvate. The fermentation products were acetate, CO2 and H2. The pH range for growth was 2.9-6.5, with an optimum at 4.5. The temperature range for growth was 42-70 degrees C, with an optimum at 55 degrees C. The G+C content of DNA was 58 mol%. Phylogenetic analysis of the 16S rRNA gene showed that strain 3408-1T belongs to the family Thermoanaerobacteraceae, order Thermoanaerobacterales and was distantly related to the species of the genus Ammonifex(93-94 % sequence similarity). On the basis of physiological properties and results of phylogenetic analysis, strain 3408-1T is considered to represent a novel species of a new genus, for which the name Desulfothermobacter acidiphilus gen. nov., sp. nov. is proposed. The type strain is 3408-1T (=DSM 105356T=VKM B-3183T). PMID- 29458538 TI - The double adjuvants LTB and CpG significantly enhanced the immuno-protective effects of recombinant GIT derived from Staphylococcus aureus and Streptococcus in mice. AB - PURPOSE: In this study, we prepared GapC1-150-IsdB126-361-TRAP (GIT) proteins plus heat-labile enterotoxin B (LTB) as an intra-molecular adjuvant, together with CpG to further enhance its immunogenicity. METHODOLOGY: Initially, the target genes were acquired and inserted into pET-32a (+) vectors to express LTB GIT protein. LTB-GIT expression was confirmed by Western blotting and its immunocompetence was estimated through ELISA. Further, we immunized BALB/c mice with the LTB-GIT plus CpG adjuvant. After the second immunization, the antigen specific CD4+ cell responses for IFN-gamma, IL-2, IL-4 and IL-10 were monitored by intracellular cytokine staining (ICS) assay. After the third immunization, the level of IgG antibodies in the serum from immunized groups was assessed by ELISA, and the protective immune response was appraised by Staphylococcus aureus and Streptococcus dysgalactiae challenge. RESULTS: The ELISA results showed that the OD450nm value of the LTB-GIT group was significantly higher than that of the BSA group. The group immunized with LTB-GIT plus CpG exhibited significantly stronger CD4+ T cell responses for IFN-gamma, IL-2, IL-4 and IL-10 compared to the group immunized with LTB-GIT, GIT alone orLTB-GIT plus CpG. In addition, the group immunized with LTB-GIT plus CpG generated the highest level of IgG antibodies against GIT among all of the groups, and our results also showed that LTB-GIT plus CpG markedly improved the survival percentage of mice compared to other groups. CONCLUSION: We confirmed that the novel double adjuvants, LTB and CpG, are able to significantly improve GIT-induced immune responses. This formula could be a promising strategy for enhancing the immune efficacy of multi-subunit vaccines against Staphylococcus aureus and streptococcal infection. PMID- 29458540 TI - Survival of bactericidal antibiotic treatment by tolerant persister cells of Klebsiella pneumoniae. AB - PURPOSE: Persister cells, a subpopulation of tolerant cells within the bacterial culture, are commonly thought to be responsible for antibiotic therapy failure and infection recurrence. Klebsiella pneumoniae is a notorious human pathogen for its increasing resistance to antibiotics and wide involvement in severe infections. In this study, we aimed to investigate the persister subpopulation of K. pneumoniae. METHODOLOGY: The presence of persisters in K. pneumoniae was determined by treatment with high concentrations of antibiotics, used alone or in combination. The effect of low level of antibiotics on persister formation was investigated by pre-exposure of cells to antibiotics with low concentrations followed by higher doses. The dependence of persister levels on growth phase was determined by measuring the survival ability of cells along the growth stages upon exposure to a high concentration of antibiotic. Analysis on persister type was carried out by persister elimination assays.Results/Key findings. We show that K. pneumoniae produces high levels of tolerant persister cells to survive treatment by a variety of high concentrations of bactericidal antibiotics and persister formation is prevalent among K. pneumoniae clinical strains. Besides, we find that persister cells can be induced by low concentrations of antibiotics. Finally, we provide evidence that persister formation is growth phase-dependent and Type II persisters dominate the persister subpopulation during the entire exponential phase of K. pneumoniae. CONCLUSION: Our study describes the formation of tolerant persister cells that allow survival of treatment by high concentrations of antibiotics in K. pneumoniae. PMID- 29458539 TI - Immunogenicity in chickens with orally administered recombinant chicken-borne Lactobacillus saerimneri expressing FimA and OmpC antigen of O78 avian pathogenic Escherichia coli. AB - PURPOSE: Avian colibacillosis is responsible for economic losses to poultry producers worldwide. To combat this, we aimed to develop an effective oral vaccine for chicken against O78 avian pathogenic Escherichia coli (APEC) infection through a Lactobacillus delivery system. METHODOLOGY: Eight Lactobacillus strains isolated from the intestines of broiler chickens were evaluated based on their in vitro adherence ability to assess their potential as a delivery vector. Fimbrial subunit A (FimA) and outer-membrane protein C (OmpC) of APEC with and without fusion to dendritic cell-targeting peptide (DCpep) and microfold cell-targeting peptide (Co1) were displayed on the surface of Lactobacillus saerimneri M-11 and yielded vaccine groups (pPG-ompC-fimA/M-11 and pPG-ompC-fimA-Co1-DCpep/M-11, respectively). The colonization of the recombinant strains in vivo was assessed and the immunogenicity and protective efficacy of orally administered recombinant strains in chickens were evaluated. RESULTS: The colonization of the recombinant strains in vivo revealed no significant differences between the recombinant and wild-type strains. Chickens orally administered with vaccine groups showed significantly higher levels of OmpC/FimA specific IgG in serum and mucosal IgA in cecum lavage, nasal lavage and stool compared to the pPG/M-11 group. After challenge with APEC CVCC1553, better protective efficacy was observed in chickens orally immunized with pPG-ompC fimA/M-11 and pPG-ompC-fimA-Co1-DCpep/M-11, but no significant differences were observed between the two groups. CONCLUSIONS: Recombinant chicken-borne L. saerimneri M-11 showed good immunogenicity in chickens, suggesting that it may be a promising vaccine candidate against APEC infections. However, the activity of mammalian DCpep and Co1 was not significant in chickens. PMID- 29458541 TI - Direct rapid antibiotic susceptibility test (dRAST) for blood culture and its potential usefulness in clinical practice. AB - PURPOSE: The direct rapid antibiotic susceptibility test (dRAST), based on analysing changes in bacterial micro-colonies under antibiotic conditions, detects antibiotic resistance within 6 h of direct smear examination results. This study aimed to assess the accuracy of dRAST and evaluate its potential usefulness for improving selection of appropriate antibiotic in real clinical practice settings. METHODOLOGY: We evaluated the accuracy of dRAST by comparing the antibiotic treatments that should have been administered based on dRAST results and the broth microdilution (BMD) test and its potential usefulness via simulation. RESULT: For 49/52 (94.2 %) patients with Gram-positive bacteraemia and 66/67 (98.5 %) patients with Gram-negative bacteraemia, antibiotics indicated by dRAST results were the same as those indicated by the BMD test. Among 34 patients with ineffective and suboptimal treatment, 19 (55.9 %) of patients could have received optimal treatment 1 to 2 days earlier with dRAST results. Among 33 patients given unnecessary broad-spectrum antibiotics, 1 to 2 days earlier de escalation could have been possible for 27 (81.8 %) patients based on dRAST results. CONCLUSION: The introduction of dRAST could increase the use of optimal antibiotics and reduce unnecessary broad-spectrum antibiotic use in the early period of bacteraemia. PMID- 29458542 TI - Description of Bacillus kexueae sp. nov. and Bacillus manusensis sp. nov., isolated from hydrothermal sediments. AB - Two Gram-staining-positive, strictly aerobic bacilli, designated as strains Ma50 5T and Ma50-6T, were isolated from the hydrothermal sediments of Manus Basin in the western Pacific Ocean. Based on 16S rRNA gene sequence, strains Ma50-5T and Ma50-6T were most closely related to Bacillus alveayuensis (97.0 and 97.2 % identity, respectively). The 16S rRNA gene sequence identity between strains Ma50 5T and Ma50-6T was 97.4 %. The identities between strains Ma50-5T and Ma50-6T and other closely related organisms were below 97.0 %. The G+C contents of the genomic DNA of strains Ma50-5T and Ma50-6T were 43.4 and 47.6 mol%, respectively. The major fatty acids (>10 %) of both strains were iso-C15 : 0 and iso-C17 : 0. The predominant isoprenoid quinone detected in both strains was menaquinone-7. Phylogenetic, physiological, biochemical and morphological analyses suggested that strains Ma50-5T and Ma50-6T represent two novel species of the genus Bacillus, for which the names Bacillus kexueae sp. nov. (type strain Ma50-5T=KCTC 33881T=CCTCC AB 2017020T) and Bacillus manusensis sp. nov. (type strain Ma50 6T=KCTC 33882T=CCTCC AB 2017019T), respectively, are proposed.

AB - A Gram-stain-negative, rod-shaped, red-pigmented, aerobic bacterium, strain M2T, was isolated from a seawater sample collected from the western Pacific Ocean at a depth of 1000 m and characterized using polyphasic taxonomy. Strain M2T was catalase-positive and oxidase-negative. Cells grew at 4-33 degrees C (optimum, 25 degrees C), at pH 6-9 (optimum, 7) and with 0-4 % (w/v) (optimum, 1 %) NaCl. Phylogenetic trees based on 16S rRNA gene sequences showed that strain M2T was associated with the genus Hymenobacter. Strain M2T showed the highest 16S rRNA gene sequence similarities to Hymenobacter actinosclerus CCUG 39621T (95.7 %), Hymenobacter tibetensis XTM003T (95.6 %) and Hymenobacter psychrotolerans Tibet IIU11T (95.2 %). The DNA G+C content was 59.98 mol%. Strain M2T contained C16 : 1omega5c (25.0 %), iso-C15 : 0 (23.9 %) and summed feature 3 (C16 : 1omega6c and/or C16 : 1omega7c, 20.4 %) as major cellular fatty acids. The major quinone of strain M2T was menaquinone 7 and the major polar lipid was phosphatidylethanolamine. The major polyamine of strain M2T was sym homospermidine. The phylogenetic analysis and physiological and biochemical data showed that strain M2T should be classified as representing a novel species of the genus Hymenobacter, for which the name Hymenobacter profundi sp. nov. is proposed. The type strain is M2T (=CCTCC AB 2017185T=KCTC 62120T). PMID- 29458544 TI - Antimicrobial activity against Mycobacterium tuberculosis under in vitro lipid rich dormancy conditions. AB - Although tuberculosis treatment is dependent on drug-susceptibility testing (DST) and molecular drug-resistance detection, treatment failure and relapse remain a challenge. This could be partially due to the emergence of antibiotic-tolerant dormant mycobacteria, where host lipids have been shown to play an important role. This study evaluated the susceptibility of Mycobacterium tuberculosis to two antibiotic combinations - rifampicin, moxifloxacin, amikacin and metronidazole (RIF-MXF-AMK-MTZ), and rifampicin, moxifloxacin, amikacin and pretomanid (RIF-MXF-AMK-PA) - in a lipid-rich dormancy model. Although their effectiveness in in vitro cultures with dextrose as a carbon source has been proved, we observed that none of the antibiotic mixtures were bactericidal in the presence of lipids. The presence of lipids may confer tolerance to M. tuberculosis against the mixture of antibiotics tested and such tolerance could be even higher during the dormant stages. The implementation of lipids in DST on clinical isolates could potentially lead to a better treatment strategy. PMID- 29458545 TI - Predominance of community-associated sequence type 59 methicillin-resistant Staphylococcus aureus in a paediatric intensive care unit. AB - PURPOSE: To investigate the distribution of molecular types of methicillin resistant Staphylococcus aureus (MRSA) in a paediatric intensive care unit (PICU) according to their community-associated (CA) and hospital-associated (HA) source of acquisition, and thus assess the degree to which CA-MRSA has been introduced into the PICU. METHODOLOGY: We implemented an MRSA surveillance in a PICU during 2013-2016 and investigated the genetic diversity of the isolates retrospectively using three genetic typing methods, as well as antibiograms and virulence factor profiles.Results/Key findings. From 2684 specimens, we identified 60 MRSA isolates, 43 of which were ST59 CA-MRSA. These 43 ST59 MRSA isolates could be further subtyped into 2 clusters and 7 sporadic isolates by pulsed-field gel electrophoresis, and 3 spa types, which demonstrated the genetic diversity in ST59 MRSA. Phenotypic diversity was also demonstrated among these ST59 MRSA isolates, with 12 virulence factor profiles and 4 antibiograms being identified. Epidemiological information showed that 43 ST59 MRSA isolates were both community associated (15 isolates) and hospital-associated (28 isolates) and caused colonization and various types of infections in different age groups of children. CONCLUSIONS: Our results show that a predominant ST59 CA-MRSA has been introduced into the PICU to a significant extent. This has caused the ST59 HA-MRSA and CA MRSA in the PICU to be indistinguishable. Our results also demonstrate that when we are interpreting situations where the causative agents of infections focus on very limited pathogenic clones, combined typing methods and epidemiological information are needed to investigate isolates' genetic and phenotypic diversity to distinguish an outbreak from endemic cases. PMID- 29458546 TI - Pedobacter agrisoli sp. nov., isolated from farmland soil. AB - A Gram-stain-negative, aerobic, non-motile, non-spore-forming and rod-shaped bacterium, designated YHM-9T, was isolated from soil in Yangquan, Shanxi Province, PR China. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain YHM-9T belonged to the genus Pedobacter and shared the highest similarity (97.4 %) to the type strain Pedobacter lignilitoris W-WS13T. Strain YHM-9T exhibited low DNA-DNA relatedness with P. lignilitoris W-WS13T (21.7+/-1.3 %). The DNA G+C content was 38.9 mol%. The major fatty acids were iso-C15 : 0, summed feature 3 (C16 : 1omega7c and/or C16 : 1omega6c) and iso-C17 : 0 3-OH. The respiratory quinone was MK-7, the major polyamine was sym-homospermidine and the major polar lipids were phosphatidylethanolamine. Based on the morphological, physiological, biochemical and chemotaxonomic characteristics, strain YHM-9T was recognized as a representative of a novel species within the genus Pedobacter, for which the name Pedobacteragrisoli sp. nov. is proposed. The type strain is YHM-9T (=JCM 32093T=CCTCC AB 2017125T). PMID- 29458548 TI - Amoxicillin-tolerant Pasteurella multocida strain isolated from chronic dermohypodermitis after suboptimal exposure to amoxicillin is not associated with reduced growth rate. AB - Pasteurella multocida is rarely observed in human chronic infections. A Pasteurella multocida strain was isolated from a skin biopsy of chronic dermohypodermitis in a 21-year-old woman without an immunocompromised state. As this strain was viable one month after a cat scratch despite treatment by amoxicillin-clavulanic acid, we compared this strain's growth rate, amoxicillin Minimal Inhibitory and Bactericidal Concentrations (MIC and MBC), resistance to serum and ability to activate neutrophil granulocytes with those of control strains isolated during acute infections in humans without previous antibiotics exposure. This particular strain was not more resistant to serum and did not induce a lower phagocytic activity than control strains. It did not grow more slowly than control strains even after suboptimal exposure to amoxicillin. This particular strain was tolerant to amoxicillin but tolerance did not appear sufficient alone for the induction of a chronic infection in a host without an immunocompromised state. PMID- 29458547 TI - The effect of P38 MAP kinase inhibition in a mouse model of influenza. AB - PURPOSE: Influenza viruses are a common cause of human respiratory infections, resulting in epidemics of high morbidity and mortality. We investigated the effect of a novel mitogen-activated protein kinase (MAPK) inhibitor in vitro and in a murine influenza model to further explore whether p38 MAPK inhibition could reduce viral replication. METHODS: In vitro, the antiviral effect of p38 MAPK inhibitor BCT194 was evaluated in differentiated human bronchial epithelial cells (HBECs); in vivo, female BALB/c mice were infected intranasally with 150 pfu of influenza H1N1 A/Puerto Rico/8/34 and treated with BCT197 (a closely related p38 MAPK inhibitor with an IC50 value of<1 uM, currently in clinical testing), dexamethasone or oseltamivir (Tamiflu) starting 24 h post infection. Body weight, bronchoalveolar lavage cells, cytokines, total protein and lactate dehydrogenase as well as serum cytokines were measured; a subset of animals was evaluated histopathologically.Results/Key findings. p38MAP kinase inhibition with BCT194 had no impact on influenza replication in HBECs. When examining BCT197 in vivo, and comparing to vehicle-treated animals, reduced weight loss, improvement in survival and lack of impaired viral control was observed at BCT197 concentrations relevant to those being used in clinical trials of acute exacerbations of chronic obstructive pulmonary disease; at higher concentrations of BCT197 these effects were reduced. CONCLUSIONS: Compared to vehicle treatment, BCT197 (administered at a clinically relevant concentration) improved outcomes in a mouse model of influenza. This is encouraging given that the use of innate inflammatory pathway inhibitors may raise concerns of negative effects on infection regulation. PMID- 29458549 TI - Tessaracoccus aquimaris sp. nov., isolated from the intestine of a Korean rockfish, Sebastes schlegelii, from a marine aquaculture pond. AB - A novel coccus-shaped, Gram-stain-positive, non-motile and aerobic bacterium, designated strain NSG39T, was isolated from the intestine of a Korean rockfish, Sebastes schlegelii. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the newly isolated strain NSG39T was closely related to Tessaracoccus flavus RP1T (98.0 %). The isolate grew at 15-37 degrees C, pH 7-9 and 0-4 % (w/v) salinity, with optimal growth at 30 degrees C, pH 8 and 0 % (w/v) salinity. The cell wall of the organism contained ll-diaminopimelic acid as a diagnostic diamino acid, and ribose, mannose, glucose and galactose as diagnostic sugars. The polar lipid comprised diphosphatidylglycerol, phosphatidylglycerol, three glycolipids and four unidentified polar lipids. The major cellular fatty acid was anteiso-C15 : 0 (47.2 %). The major menaquinone was MK-9 (H4). The DNA G+C content of the isolate was 68.8 mol%. The genome-based orthologous average nucleotide identity value for strain NSG39T and T. flavus RP1T was 76.6 %. Based on the phylogenetic analysis and its biological characteristics, strain NSG39T is considered to represent a novel species of the genus Tessaracoccus, for which the name Tessaracoccus aquimaris is proposed. The type strain is NSG39T (=KACC 17540T=JCM 19289T). PMID- 29458550 TI - Molecular epidemiology of Bordetella pertussis in Greece, 2010-2015. AB - PURPOSE: To determine the predominant strains of Bordetella pertussis in Greece during 2010-2015. METHODOLOGY: Infants and children (n=1150) (15 days to 14 years) of Greek, Roma and immigrant origin with different vaccination statuses were hospitalized in Athens, Greece with suspected pertussis infection. IS481/IS1001 real-time PCR confirmed Bordetella spp./B. pertussis infection in 300 samples. A subset of samples (n=153) were analysed by multi-locus variable number tandem repeat analysis (MLVA) and (n=25) by sequence-based typing of the toxin promotor region (ptxP) on DNA extracted from clinical specimens.Results/Key findings. A complete MLVA profile was determined in 66 out of 153 samples; the B. pertussis MLVA type 27 (n=55) was the dominant genotype and all tested samples (n=25) expressed the ptxP3 genotype. The vaccine coverage in the Greek population was 90 %; however, the study population expressed complete coverage in 2 out of 264 infants (0-11 months) and in 20 out of 36 children (1-14 years). Roma and immigrant minorities represent 7 % of the Greek population, but make up 50 % of the study population, indicating a low vaccine coverage among these groups. CONCLUSIONS: The B. pertussis MT27 and ptxP3 genotype is dominant in Greek, Roma and immigrant infants and children hospitalized in Greece. Thus, the predominant MLVA genotype in Greece is similar to other countries using acellular vaccines. PMID- 29458551 TI - Short- and long-term influence of the levonorgestrel-releasing intrauterine system (Mirena(r)) on vaginal microbiota and Candida. AB - BACKGROUND: Recurrent vulvovaginal infections are a frequent complaint in young women in need of contraception. However, the influence of the contraceptive method on the course of the disease is not well known. AIM: To investigate the influence of the levonorgestrel-releasing intrauterine-system (LNG-IUS) on the vaginal microflora. METHODS: Short-term (3 months) and long-term (1 to 5 years) changes of vaginal microbiota were compared with pre-insertion values in 252 women presenting for LNG-IUS insertion. Detailed microscopy on vaginal fluid was used to define lactobacillary grades (LBGs), bacterial vaginosis (BV), aerobic vaginitis (AV) and the presence of Candida. Cultures for enteric aerobic bacteria and Candida were used to back up the microscopy findings. Fisher's test was used to compare vaginal microbiome changes pre- and post-insertion. RESULTS: Compared to the pre-insertion period, we found a temporary worsening in LBGs and increased rates of BV and AV after 3 months of LNG-IUS. After 1 and 5 years, however, these changes were reversed, with a complete restoration to pre-insertion levels. Candida increased significantly after long-term carriage of LNG-IUS compared to the period before insertion [OR 2.0 (CL951.1-3.5), P=0.017]. CONCLUSIONS: Short term use of LNG-IUS temporarily decreases lactobacillary dominance, and increases LBG, AV and BV, but after 1 to 5 years these characteristics return to pre insertion levels, reducing the risk of complications to baseline levels. Candida colonization, on the other hand, is twice as high after 1 to 5 years of LNG-IUS use, making it less indicated for long-term use in patients with or at risk for recurrent vulvovaginal candidosis. PMID- 29458552 TI - Etest to detect drug-resistant Neisseria gonorrhoeae to contemporary treatment; methodological issues concerning accuracy and reproducibility. PMID- 29458553 TI - Streptomyces coelicolor strains lacking polyprenol phosphate mannose synthase and protein O-mannosyl transferase are hyper-susceptible to multiple antibiotics. AB - Polyprenol phosphate mannose (PPM) is a lipid-linked sugar donor used by extra cytoplasmic glycosyl tranferases in bacteria. PPM is synthesiszed by polyprenol phosphate mannose synthase, Ppm1, and in most Actinobacteria is used as the sugar donor for protein O-mannosyl transferase, Pmt, in protein glycosylation. Ppm1 and Pmt have homologues in yeasts and humans, where they are required for protein O mannosylation. Actinobacteria also use PPM for lipoglycan biosynthesis. Here we show that ppm1 mutants of Streptomyces coelicolor have increased susceptibility to a number of antibiotics that target cell wall biosynthesis. The pmt mutants also have mildly increased antibiotic susceptibilities, in particular to beta lactams and vancomycin. Despite normal induction of the vancomycin gene cluster, vanSRJKHAX, the pmt and ppm1 mutants remained highly vancomycin sensitive indicating that the mechanism of resistance is blocked post-transcriptionally. Differential RNA expression analysis indicated that catabolic pathways were downregulated and anabolic ones upregulated in the ppm1 mutant compared to the parent or complemented strains. Of note was the increase in expression of fatty acid biosynthetic genes in the ppm1- mutant. A change in lipid composition was confirmed using Raman spectroscopy, which showed that the ppm1- mutant had a greater relative proportion of unsaturated fatty acids compared to the parent or the complemented mutant. Taken together, these data suggest that an inability to synthesize PPM (ppm1) and loss of the glycoproteome (pmt- mutant) can detrimentally affect membrane or cell envelope functions leading to loss of intrinsic and, in the case of vancomycin, acquired antibiotic resistance. PMID- 29458554 TI - Genetic shifts in methicillin-resistant Staphylococcus aureus epidemic clones and toxin gene profiles in Japan: comparative analysis among pre-epidemic, epidemic and post-epidemic phases. AB - PURPOSE: The decline in methicillin-resistant Staphylococcus aureus (MRSA) isolation rates has become a general observation worldwide, including Japan. We hypothesized that some genetic shift in MRSA might cause this phenomenon, and therefore we investigated the genetic profiles among MRSA clinical isolates obtained from three different epidemic phases in Japan. METHODOLOGY: A total of 353 MRSA isolates were selected from 202 medical facilities in 1990 (pre-epidemic phase), 2004 (epidemic phase) and 2016 (post-epidemic phase). Molecular typing was performed by PCR detection of 22 genes using the polymerase chain reaction (PCR)-based ORF typing (POT) system, including an additional eight genes including small genomic islets and seven toxin genes. RESULTS: Isolates with a POT1 of score 93, identified as presumed clonal complex (pCC)5-staphylococcal cassette chromosome mec (SCCmec) type II including ST5-SCCmec type II New York/Japan clone, represented the major epidemic MRSA lineage in 1990 and 2004. In 2016, however, a marked decrease in isolates with a POT1 score of 93, along with changes in the epidemiology of toxin genes carried, was noted, where the carriers of tst genes including the tst-sec combination were markedly reduced, and those possessing the seb gene alone were markedly increased. Rather, isolates with a POT1 score of 106, including pCC1 or pCC8 among the isolates with SCCmec type IV, which often links to community-associated MRSA, were predominant. Interestingly, the pCC1 and pCC8 lineages were related to sea and tst-sec carriage, respectively. CONCLUSIONS: Over time, a transition in MRSA genetic profiles from a POT1 score of 93 in 1990 and 2004 to 106 in 2014 was found in Japan. PMID- 29458555 TI - Does Toxoplasma gondii infection impact liver transplantation outcomes? A systematic review. AB - PURPOSE: Approximately one-third of the world's population has Toxoplasma gondii infection, and one of the main routes of transmission is organ transplantation. The aim of this study was to evaluate the impact of Toxoplasma infection on liver transplantation patients. METHODOLOGY: We searched PubMed, Lilacs, Medline, Science direct, Scielo, Ebsco, Springer, Wiley, Ovid and Google Scholar for reports published up to June 2017, and a systematic review was performed. RESULTS: Twenty cases were analysed before and after liver transplantation. Primary and reactivated infections were investigated. Before transplantation, positive IgG antibodies were the predominant serological markers in donors and recipients: 40 % (D+/R-), 20 % (D+/R+) and 20 % (D-/R+). IgM was present in only 5 % of the donors (D+/R-). In four cases, the serological markers were not specified or were negative (D?/R? or D?/R-). After transplantation, IgM anti Toxoplasma antibodies were found in 30 % of the recipients, and in 67 % of the seronegative recipients the presence of Toxoplasma DNA or tachyzoites was reported, suggesting a primary infection. Clinical symptoms were meningitis, massive cerebral oedema, encephalitis and seizures. Treatment was administered in 70 % of the patients, and 40 % died after presenting symptoms associated with Toxoplasma infection. CONCLUSIONS: Although we review Toxoplasma infection and liver transplantation cases, problems associated with the parasite may be greater than identified. Hence, follow-up studies on Toxoplasma infection in liver transplantation patients are recommended. PMID- 29458556 TI - Sequence analysis of the G gene of hRSVA ON1 genotype from Egyptian children with acute respiratory tract infections. AB - Human respiratory syncytial virus causes severe lower respiratory tract infection in neonates and children. Genotype ON1, with duplication of 72-nt in the G gene, was first detected in Canada and then recorded in other countries. In the current study, we describe the first detection of the ON1 genotype among children in Egypt in 2014/2015. Sequence analysis of the full-attachment G gene revealed that the majority of the strains examined were related to the ON1 genotype and only one sample related to N1 genotype. The Egyptian ON1 strains showed unique non silent mutations in addition to variable mutations near the antigenic sites in comparison to the original ON1 ancestor strain. Continuous surveillance of hRSV regionally and globally is needed to understand the evolutionary mechanisms and strategies adopted by hRSV and their inducers for better adaption to the host. PMID- 29458557 TI - Evaluation of greater wax moth larvae, Galleria mellonella, as a novel in vivo model for non-tuberculosis Mycobacteria infections and antibiotic treatments. AB - PURPOSE: To evaluate the suitability of Galleria mellonella larvae as an in vivo model and drug-screening tool for mycobacteria infections. METHODOLOGY: Larvae were infected using a range of inoculum sizes from a variety of rapid-growing mycobacteria, including strains of M. fortuitum, M. marinum and M. aurum. Larval survival, internal bacterial burden and the effects of amikacin, ciprofloxacin, ethambutol, isoniazid and rifampicin treatment on larval survival were measured over 144 h. The effects of these anti-mycobacterial drugs on phagocytosis and circulating haemocyte numbers were also examined using microscopy. RESULTS: Larval survival decreased after infection with M. fortuitum and M. marinum in a dose-dependent manner, but remained unaffected by M. aurum. Heat-killed bacteria did not cause larval death. Where antibiotic monotherapy was efficacious, larval survival post-infection increased in a dose-dependent fashion. However, efficacy varied between different antibiotics and species of infecting mycobacteria and, apart from rifampicin, efficacy in vivo correlated poorly with the in vitro minimum inhibitory concentrations (MICs). Combinations of antibiotics led to higher survival of infected larvae than antibiotic monotherapy. Selected antibiotic treatments that enhanced larval survival reduced the overall internal burden of infecting mycobacteria, but did not eradicate the pathogens. Administration of amikacin or ethambutol to uninfected larvae induced an initial transient increase in the numbers of circulating haemocytes and reduced the phagocytic rate of haemocytes in larvae infected with M. marinum. CONCLUSIONS: This report demonstrates the potential of employing a wax moth larvae model for studying fast-growing mycobacteria infections, and as a cheap, effective system for initial screening of novel treatments. PMID- 29458558 TI - High prevalence of fluoroquinolone resistance amongst commensal flora of antibiotic naive neonates: a study from India. AB - BACKGROUND: The emergence of resistance amongst commensal flora is a serious threat to the community. However, there is paucity of data regarding antibiotic resistance in commensals in the absence of antibiotic pressure. METHODS: Altogether, 100 vaginally delivered antibiotic naive exclusively breastfed neonates were selected. Stool samples collected on day (D)1, D21 and D60 of birth were cultured. Enterobacteriaceae isolates were screened for nalidixic acid (NA) and ciprofloxacin susceptibility as per CLSI guidelines. In 28 randomly selected neonates, isolates (n=92) resistant to NA and ciprofloxacin were characterized for the presence of plasmid-mediated quinolone resistance (PMQR) genes (qnrA, qnrB and qnrS, qepAand aac(6')-Ib-cr) and mutations in the quinolone resistance determining region (QRDR) of gyrA and parC genes by specific primers and confirmed by sequencing. RESULTS: A total of 343 Enterobacteriaceae were isolated from 100 neonates. On D1, 58 % of neonates were colonized with at least one Enterobacteriaceae predominantly E. coli. Overall resistance to NA was 60 % but ciprofloxacin resistance increased significantly from 15 % (14/96) on D1 to 38 % (50/132) on D60 (P-value <0.001). The predominant mechanism of fluoroquinolone resistance was mutation in gyrA (n=49) with or without PMQR. PMQR carrying isolates increased more than fivefold from D1 to D60. CONCLUSION: A high level of fluoroquinolone resistance in gut flora of antibiotic naive and exclusively breastfed neonates suggests a rampant rise of resistance in the community. The source of resistance genes on D1 is probably maternal flora acquired at birth. High load of PMQR genes in commensal flora are a potential source of spread to pathogenic organisms. PMID- 29458560 TI - cAMP-CRP acts as a key regulator for the viable but non-culturable state in Escherichia coli. AB - A variety of bacteria, including Escherichia coli, are known to enter the viable but non-culturable (VBNC) state under various stress conditions. During this state, cells lose colony-forming activities on conventional agar plates while retaining signs of viability. Diverse environmental stresses including starvation induce the VBNC state. However, little is known about the genetic mechanism inducing this state. Here, we aimed to reveal the genetic determinants of the VBNC state of E. coli. We hypothesized that the VBNC state is a process wherein specific gene products important for colony formation are depleted during the extended period of stress conditions. If so, higher expression of these genes would maintain colony-forming activities, thereby restraining cells from entering the VBNC state. From an E. coli plasmid-encoded ORF library, we identified genes that were responsible for maintaining high colony-forming activities after exposure to starvation condition. Among these, cpdA encoding cAMP phosphodiesterase exhibited higher performance in the maintenance of colony forming activities. As cpdA overexpression decreases intracellular cAMP, cAMP or its complex with cAMP-receptor protein (CRP) may negatively regulate colony forming activities under stress conditions. We confirmed this using deletion mutants lacking adenylate cyclase or CRP. These mutants fully maintained colony forming activities even after a long period of starvation, while wild-type cells lost most of this activity. Thus, we concluded that the lack of cAMP-CRP effectively retains high colony-forming activities, indicating that cAMP-CRP acts as a positive regulator necessary for the induction of the VBNC state in E. coli. PMID- 29458559 TI - Detection of novel gammaherpesviruses from fruit bats in Indonesia. AB - Bats are an important natural reservoir of zoonotic viral pathogens. We previously isolated an alphaherpesvirus in fruit bats in Indonesia, and here establish the presence of viruses belonging to other taxa of the family Herpesviridae. We screened the same fruit bat population with pan-herpesvirus PCR and discovered 68 sequences of novel gammaherpesvirus, designated 'megabat gammaherpesvirus' (MgGHV). A phylogenetic analysis of approximately 3.4 kbp of continuous MgGHV sequences encompassing the glycoprotein B gene and DNA polymerase gene revealed that the MgGHV sequences are distinct from those of other reported gammaherpesviruses. Further analysis suggested the existence of co infections of herpesviruses in Indonesian fruit bats. Our findings extend our understanding of the infectious cycles of herpesviruses in bats in Indonesia and the phylogenetic diversity of the gammaherpesviruses. PMID- 29458561 TI - ICTV Virus Taxonomy Profile: Guttaviridae. AB - Guttaviridae is a family of enveloped viruses infecting hyperthermophilic archaea. The virions are ovoid or droplet-shaped, with a diameter of 55-80 nm and a length of 75-130 nm. The genome is a circular dsDNA molecule of around 14-20 kbp. The droplet-shaped morphology is unprecedented among viruses of bacteria and eukaryotes and represents a group of archaea-specific virion morphotypes. The family includes two genera, Alphaguttavirus and Betaguttavirus, each with a single species. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the taxonomy of Guttaviridae, which is available at www.ictv.global/report/guttaviridae. PMID- 29458562 TI - The fission yeast Schizosaccharomyces pombe Mtf2 is required for mitochondrial cox1 gene expression. AB - Mitochondrial gene expression is essential for adenosine triphosphate synthesis via oxidative phosphorylation, which is the universal energy currency of cells. Here, we report the identification and characterization of a homologue of Saccharomyces cerevisiae Mtf2 (also called Nam1) in Schizosaccharomyces pombe. The Deltamtf2 mutant with the intron-containing mitochondrial DNA (mtDNA) exhibited impaired growth on a rich medium containing the non-fermentable carbon source glycerol, suggesting that mtf2 is involved in mitochondrial function. mtf2 deletion in a mitochondrial intron-containing background resulted in a barely detectable level of the cox1 mRNA and a reduction in the level of the cob1 mRNA, and severely impaired cox1 translation. In contrast, mtf2 deletion in a mitochondrial intron-less background did not affect the levels of cox1 and cob1 mRNAs. However, Cox1 synthesis could not be restored to the control level in the Deltamtf2 mutant with intron-less mtDNA. Our results suggest that unlike its counterpart in S. cerevisiae which plays a general role in synthesis of mtDNA encoded proteins, S. pombe Mtf2 primarily functions in cox1 translation and the effect of mtf2 deletion on splicing of introns in mtDNA is likely due to a deficiency in the synthesis of intron-encoded maturases. PMID- 29458563 TI - Bacillus fermenti sp. nov., an indigo-reducing obligate alkaliphile isolated from indigo fermentation liquor for dyeing. AB - The indigo-reducing, facultatively anaerobic and obligately alkaliphilic strains Bf-1T, Bf-2 and Bf-4 were isolated from an indigo fermentation liquor used for dyeing, which uses sukumo [composted Polygonum indigo (Polygonum tinctorium Lour.) leaves] as a basic ingredient and was obtained from a craft centre in Date City, Hokkaido, Japan. The 16S rRNA gene sequence analyses indicated that the closest neighbours of strain Bf-1T are Bacillus maritimus DSM 100413T (98.3 % 16S rRNA gene sequence similarity), Bacillus persicus DSM 25386T (98.2 %) and Bacillus rigiliprofundi LMG 28275T (97.7 %). The 16S rRNA gene sequence of strain Bf-1T was almost identical to the sequences of strains Bf-2 and Bf-4 (99.9 %). Cells of strain Bf-1T stained Gram-positive and formed straight rods that achieved motility through a pair of subpolar flagella. Strain Bf-1T grew at temperatures of between 15 and 45 degrees C with optimum growth at 33-40 degrees C. The strain grew in the pH range of pH 8-12, with optimum growth at pH 10. The isoprenoid quinone detected was menaquinone-7 (MK-7), and the DNA G+C content was 41.7 %. The whole-cell fatty acid profile mainly (>10 %) consisted of iso-C15 : 0 and iso-C16 : 0. Phylogenetically related neighbours, although demonstrating high 16S rRNA gene sequence similarity (>97.6 %) with strain Bf-1T, exhibited less than 9 % relatedness in DNA-DNA hybridization experiments. Based on evidence from this polyphasic study, the isolates represent a novel species, for which the name Bacillus fermenti sp. nov. is proposed. The type strain of this species is Bf-1T (=JCM 31807T=NCIMB 15079T). PMID- 29458564 TI - Veillonella infantium sp. nov., an anaerobic, Gram-stain-negative coccus isolated from tongue biofilm of a Thai child. AB - A strain of a novel anaerobic, Gram-stain-negative coccus was isolated from the tongue biofilm of a Thai child. This strain was shown, at the phenotypic level and based on 16S rRNA gene sequencing, to be a member of the genus Veillonella. Comparative analysis of the 16S rRNA, dnaK and rpoB gene sequences indicated that phylogenetically the strain comprised a distinct novel branch within the genus Veillonella. The novel strain showed 99.8, 95.1 and 95.9 % similarity to partial 16S rRNA, dnaK and rpoB gene sequences, respectively, to the type strains of the two most closely related species, Veillonelladispar ATCC 17748T and Veillonellatobetsuensis ATCC BAA-2400T. The novel strain could be discriminated from previously reported species of the genus Veillonella based on partial dnaK and rpoB gene sequencing and average nucleotide identity values. The major acid end-product produced by this strain was acetic acid under anaerobic conditions in trypticase-yeast extract-haemin with 1 % (w/v) glucose or fructose medium. Lactate was fermented to acetic acid and propionic acid. Based on these observations, this strain represents a novel species, for which the name Veillonella infantium sp. nov. is proposed. The type strain is T11011-4T (=JCM 31738T=TSD-88T). PMID- 29458565 TI - The DNases of pathogenic Lancefield streptococci. AB - DNases are abundant among the pathogenic streptococci, with most species harbouring genes for at least one. Despite their prevalence, however, the role for these extracellular enzymes is still relatively unclear. The DNases of the Lancefield group A Streptococcus, S. pyogenes are the best characterized, with a total of eight DNase genes identified so far. Six are known to be associated with integrated prophages. Two are chromosomally encoded, and one of these is cell wall anchored. Homologues of both prophage-associated and chromosomally encoded S. pyogenes DNases have been identified in other streptococcal species, as well as other unique DNases. A major role identified for streptococcal DNases appears to be in the destruction of extracellular traps produced by immune cells, such as neutrophils, to ensnare bacteria and kill them. These traps are composed primarily of DNA which can be degraded by the secreted and cell-wall-anchored streptococcal DNases. DNases can also reduce TLR-9 signalling to dampen the immune response and produce cytotoxic deoxyadenosine to limit phagocytosis. Upper respiratory tract infection models of S. pyogenes have identified a role for DNases in potentiating infection and transmission, possibly by limiting the immune response or through some other unknown mechanism. Streptococcal DNases may also be involved in interacting with other microbial communities through communication, bacterial killing and disruption of competitive biofilms, or control of their own biofilm production. The contribution of DNases to pathogenesis may therefore be wide ranging and extend beyond direct interference with the host immune response. PMID- 29458566 TI - Paenibacillus translucens sp. nov., isolated from tidal flat sediment. AB - A Gram-stain-variable, aerobic, rod-shaped, motile and spore-forming bacterial strain, designated CJ11T, was isolated from a tidal flat sediment sample from Ganghwa-do, Republic of Korea. Strain CJ11T grew optimally on R2A at 30 degrees C and pH 7.0. Sequencing results of the 16S rRNA gene revealed that strain CJ11T possesses two copies of the 16S rRNA gene varying at five nucleotide positions. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain CJ11T belonged to the genus Paenibacillus within the family Paenibacillaceae and was most closely related to Paenibacillus lacus KCTC 33691T (99.36-99.15 % similarity). DNA-DNA relatedness levels of strain CJ11T was 41.7 % (reciprocal, 57.8 %) to P. lacus KCTC 33691T. The G+C content of the genomic DNA was 51.0 mol%. Strain CJ11Tcontained meso-diaminopimelic acid in the cell-wall peptidoglycan. The major isoprenoid quinone was menaquinone-7. The major cellular fatty acids were anteiso-C15 : 0, C16 : 0 and iso-C16 : 0. The predominant polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, two unidentified phospholipids, an unidentified glycolipid and several unidentified lipids. On the basis of the polyphasic taxonomic study, strain CJ11T represents a novel species in the genus Paenibacillus, for which the name Paenibacillustranslucens sp. nov. is proposed. The type strain is CJ11T (=KACC 19304T=JCM 32080T). PMID- 29458567 TI - Graphene-Based Multifunctional Nanomaterials in Cancer Detection and Therapeutics.

PMID- 29458568 TI - Nanoformulations for Targeted Drug Delivery to Prostate Cancer: An Overview. AB - Cancer is the second leading causes of death worldwide and it is one of the fatal diseases that kill millions of people every year. It is characterized by uncontrolled proliferation of cells and loss of apoptosis that generates an abnormal mass of cells or tumors. Prostate cancer (PCa) is one of the most common cancers in men and the risk is higher over the age of 55-65. Currently, PCa is the second most common cancer, which causes death in men has a high prevalence with relatively lower cancer mortality risk compared to lung and colon cancer. Management of cancer remains an ongoing challenge in oncology as it is a pathophysiological and heterogeneous disease. The current treatment options such as surgery, chemotherapy, radiation therapy available for cancer therapies are inadequate due to the heterogeneity characteristics of cancer and spur demand for improved technologies. Nanotechnology is an emerging and potential platform that uses nanoparticles for the disease diagnosis to targeted drug delivery system (DDS). One of the most important active research fields of nanotechnology is nanomedicine, which provides solutions to the difficulties of conventional chemotherapy. Nanoformulation based drug delivery enhances the properties to improve the pharmacokinetics profile, bioavailability and these drug carriers increases the therapeutic efficiency compared to the regular chemotherapeutic drugs. Moreover, nanoformulated drugs help to overcome the lack of selectivity and adverse side effects of conventional chemotherapy. This review provides an overview of PCa drug delivery systems. A special emphasis is given to research work around the world in the development of nanoformulations for targeted drug delivery to PCa. PMID- 29458569 TI - Recent Progress of Wnt Pathway Inhibitor Dickkopf-1 in Liver Cancer. AB - Hepatocellular carcinoma (HCC) is one of the most common cancers around the world. Multiple etiologic factors such as virus and environment can lead to HCC. It is a challenge for us to successfully detect early HCC due to the lack of effective characterized and specific biomarkers. However, if the early diagnosis is successfully realized, it provides crucial chance for HCC patients to receive effective treatment as early as possible. Dickkopf-1 (DKK-1) is a secretary glycoprotein, which negatively regulates Wnt pathway through binding to surface receptors LRP5/6 and Kremen 1/2. The expression of DKK-1 is regulated by p53, V Myc avian myelocytomatosis viral oncogene neuroblastoma derived homolog (MYCN), beta-catenin, etc. Ectopic expression of DKK-1 can inhibit cell proliferation, or induce apoptosis with apoptosis enhancing factors. DKK-1 is low-expressed in many tumors, but overexpressed in others. Growing evidences show that DKK-1 plays complex and different roles in tumorigenesis, tumor progression and metastasis of different cancers. We herein review the recent progress in the expression and function of DKK-1 in hepatocellular carcinoma. PMID- 29458570 TI - Functional and Modified Nanocrystals Technology for Target Drug Delivery. AB - In the face of a large number of insoluble drugs, the development of nanocrystals is effective in destroying the limits of poorly soluble drug applications and becoming an indispensable route of drug delivery in the pharmaceutical industry. In addition, the proposed delivery goal is to provide more convenience and benefits and the number of researchers who are developing a number of advanced technologies try to use improved nano-drugs to improve the bioavailability of drug, drug dissolution velocity and solubility. Previously, more mature study has been done, for example, preparation of nanocrystals, the problems of safety, the route of administration and so on. This review systematically dwells upon several of the current nanocrystals technologies for target delivery by different modification technologies, such as magnetic nanocrystals, PEG and PEGylated chitosan modified nanocrystals, cationic nanocrystals and pluronic modified nanocrystals. Subsequently, the effects of surface charge and particle size on the drug targeted administration was analyzed. This review will provide a new insight for improving stability and controllability of the nanocrystals, and promote the nanocrystals technology development in targeting drug delivery. PMID- 29458571 TI - Significance of Nanoparticles and the Role of Amino Acids in Structuring Them-A Review. AB - Nanoparticles has occupied an eminent place in our tech-facilitated society. The processes involved in synthesizing nanoparticles are important not only to find their applications, but also to make them eco-friendly. Attempts are being made to replace the use of harmful surfactants/reagents by amino acids, in the due course of nanoparticle synthesis. Especially in synthesizing the multifunctional metal and metal oxide nanoparticles the use of amino acids as surfactant/as catalyst, helps to obtain required size and shape. Amino acids have the inherent property in directing and assembling the superstructures. They have the tendency to act as a capping agent and their presence during the synthesis processes alters the synthesized particles' morphology. Review has been made to study the role of amino acids like histidine, lysine, arginine in structuring ZnO, FeO, Au and Ag nanoparticles. The change in their morphology that resulted due to the addition of amino acids has been compared. It is important to understand the role of amino acids in synthesizing the nanoparticles, and so it is more important to understand the internal energy variation of the same. To achieve this, the interaction between the bio (amino acids) and non-bio (metal and metal oxide) nanoparticles are to be discussed both experimentally and theoretically. At times the theoretical characterization, especially at low dimensions, help us to understand inter-particle interaction and intra-particle interaction by determining their chemical potential and Lennard-Jones potential. This review has been concluded with a model to characterize the precursor solution (amino acids and inorganic materials) by considering the Equation of State for liquids, which could also be extended to determine the structure factor of nanoparticles. PMID- 29458572 TI - Morphology Dependent Photocatalytic Properties of ZnO Nanostructures Prepared by a Carbon-Sphere Template Method. AB - Organic contaminants are a typical byproduct of industrial wastewater, and nanostructured ZnO photocatalysts have been investigated as an environmentally benign process to remove the contaminants through a degradation process. The degradation efficiency under UV irradiation can be markedly enhanced when using a catalyst with a nanostructure. The larger specific area of a nanostructure has been found to significantly enhance degradation efficiency. The complex synthesis process, expensive material costs, and generation of environmental contaminants during the synthesis process currently hinder practical application of photocatalysts. This research provides a template for a photocatalyst that is non toxic, producing mesoporous ZnO hollow spheres and nanorods through an environmentally friendly carbon-sphere template utilizing a hydrothermal process. This research demonstrates that controlling the precursor concentration (zinc acetate) allows for the manipulation of the morphology and specific area of the ZnO nanostructures. A zinc acetate concentration of 0.171 mol/L produced uniform ZnO mesoporous hollow spheres with diameters of approximately 180 nm. Increasing the zinc acetate concentration resulted in an increase in the number of nanorods present. In contrast to nanorods, mesoporous ZnO hollow spheres have a higher specific area and higher concentration of pores in the 2-50 nm range, which result in better photocatalytic activity. This research reports the complete degradation of rhodium boride (RhB) within 50 min by means of mesoporous ZnO hollow spheres and nanorods with a degradation rate of 0.0978 min-1. PMID- 29458573 TI - Promoted Delivery of Salinomycin to Lung Cancer Through Epidermal Growth Factor Receptor Aptamers Coupled DSPE-PEG2000 Nanomicelles. AB - Initiation and recurrence of lung cancer, the most fatal cancer worldwide, are attributed to lung cancer stem cells (CSCs). Evidence suggests that cancer cells can be turned into CSCs in a spontaneous way, and therefore simultaneous elimination of lung CSCs and cancer cells is crucial to achieve effective therapy of lung cancer. In lung cancer, epidermal growth factor receptor (EGFR) is overexpressed in both CSCs and cancer cells. The present study developed salinomycin poly(ethylene glycol) 2000-distearoylphosphatidylethanolamine nanomicelles conjugated with EGFR aptamers (M-SAL-EGFR) to kill lung CSCs and cancer cells. The 24 nm sized M-SAL-EGFR was prepared by a lipid film based method. The EGFR was overexpressed in lung CSCs and cancer cells. Results revealed that the M-SAL-EGFR could efficiently bind to EGFR-overexpressing lung CSCs and cancer cells, and induced enhanced cyotoxic effect than non-targeted M SAL and salinomycin. Administration of M-SAL-EGFR in mice with lung cancer xenograft inhibited tumor growth more effectively compared with M-SAL and salinomycin. The EGFR aptamers were thus able to promote effective salinomycin delivery to lung cancer. Our results also suggest that the M-SAL-EGFR represents a promising approach for targeting both lung CSCs and cancer cells. PMID- 29458574 TI - Thermo-Sensitive PLGA-PEG-PLGA Tri-Block Copolymer Hydrogel as Three-Dimensional Cell Culture Matrix for Ovarian Cancer Cells. AB - Thermo-sensitive hydrogels which could encapsulate cells and provide a three dimensional (3D) microenvironment have great potential in building new cell culture models in vitro. In this study, a thermal responsive hydrogel based on PLGA-PEG-PLGA tri-block copolymers was developed as matrix for 3D ovarian cancer cell culturing. The gelation of PLGA-PEG-PLGA tri-block copolymer was concentration-dependent. SEM images showed the pores were suitable for the formation of 3D cell structures. Cell morphological results showed that large aggregates of ovarian cancer cells (HO8910) were formed after cultured for 10 days. Therefore, hydrogel based on PLGA-PEG-PLGA tri-block copolymers hold potential as in vitro cell culture matrix for ovarian cancer cells. PMID- 29458575 TI - Facile Preparation of Modifying Layered Double Hydroxide Nanoparticles for Drug Delivery. AB - Mg-Al-NO3 hydrotalcite (p-LDH) was employed as a carrier for the controlled release of 5-Fluorouracil (5-FU). The p-LDH was pretreated by acid-pretreatment to gain a more stable material (a-LDH) in acid medium for oral administration. It demonstrated that the a-LDH had smaller crystal size, particle sizes and higher permanent charge density (sigmap) compared with that of the p-LDH by means of XRD, SEM, FT-IR, UV-vis DRS, TG-DSC, BET/BJH and other techniques. The FU/a-LDH and FU/p-LDH delivery systems were obtained using anion-exchange method. The in vitro 5-FU drug release studies showed that no burst release phenomenon was observed at the beginning of release tests. The in vitro 5-FU release behaviors of the delivery systems at initial pH 4.6 and 7.5 were studied which could be described by first-order and Bhaskas models. Combined with the XRD and FT-IR analyses of the solid residues of the FU/a-LDH and FU/p-LDH after the release, it was found that the dissolution mechanism was mainly responsible for the release behavior of the FU/p-LDH at initial 4.6, while the anion-exchange between intercalated 5-FU and phosphate anions mechanism was responsible for the FU/a-LDH at pH 4.6 and 7.5 as well as FU/p-LDH at pH 7.5. It is concluded that the hydrotalcites could be used as the basis of a tunable drug delivery carrier for 5 FU. PMID- 29458576 TI - Synthesis of Metal-Organic Framework from Iron Nitrate and 2,6 Naphthalenedicarboxylic Acid and Its Application as Drug Carrier. AB - Metal-organic frameworks (MOFs) are highly crystalline porous organic-inorganic materials that are comprised of metal salts and organic linkers. The common synthetic methodologies of MOFs include: solvothermal, microwave-assisted, electrochemical, mechanochemical, and sonochemical routes. The synthesized MOF particles can be characterized using several characterization techniques including: X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and other analytical techniques. Recently, MOFs have garnered increasing attention due to their potential applications in numerous areas including: catalysis, gas storage and separation, drug delivery, and others. In this research paper, a new metal-organic framework was synthesized successfully from iron nitrate and 2,6-naphthalenedicarboxylic acid (1) by means of microwave irradiation (Fe-NDC-M) and (2) solvothermally using a conventional electric oven (Fe-NDC-O). They were characterized using XRD, SEM, FTIR, energy-dispersive X-ray (EDS), thermogravimetric analysis (TGA), and N2 sorption experiments. The characterization results showed that the synthesized samples were crystals with a rod-like shape. The particle diameters ranged between 50-80 nm with a length of 300-450 nm. The BJH adsorption averagepore diameters were found to be 148.551 A and 139.265 A for Fe-NDC-M and Fe-NDC-O, respectively. As a result, the new Fe-NDC-MOF particles can be used as nanocarriers for anticancer drug delivery applications utilizing the enhanced permeability and retention effect. PMID- 29458577 TI - A Novel Delivery Method of Cyclovirobuxine D for Brain-Targeting: Chitosan Coated Nanoparticles Loading Cyclovirobuxine D by Intranasal Administration. AB - The blood-brain barrier (BBB) restricts the delivery of most drugs to the brain. In our previous study, the feasibility of cyclovirobuxine D delivery to the brain by a non-invasive nasal route was evaluated. In this study, a suitable drug delivery system by way of intranasal administration was developed, which could improve brain targeting. First, a formulation of cyclovirobuxine D (CVB-D) based on chitosan nanoparticles (CS-CVB-D-NPs) was prepared by the modified ionotropic gelation method through single-factor screening experiment. The CS-CVB-D-NPs with a entrapment efficiency (EE) of (62.82+/-2.59)% were found to be of a narrow polydispersity index (PI) (0.19+/-0.01) and (235.37+/- 12.71) nm in size, with a zeta potential of (33.9 +/- 1.7) mV. The NPs possessed a sustained release characterization with in vitro release of 88.03 +/- 2.30% at 24 h. In vivo, the higher AUC0-t(brain) of CS-CVB-D-NPs by intranasal administration revealed the development of a novel brain-targeting delivery method of CVB-D. PMID- 29458578 TI - Field-Effect Transistor-Integration with TiO2 Nanoparticles for Sensing of Cardiac Troponin I Biomarker. AB - The development of electrical biosensor towards device miniaturization in order to achieve better sensitivity with enhanced electrical signal has certain limitations especially complexity in fabrication process and costs. In this paper, an alternative technique with minor modification in the device structure is presented for signal amplification by implementing ambipolar conduction in the biosensor itself. We demonstrated the field-effect transistor (FET)-based biosensor coupled back-gate for attaining a higher sensitivity with the detection of lower target abundance. To utilize the coupled back-gate as a pre-amplifier, silicon-on-insulator wafer with thicknesses of top-silicon and buried oxide (BOX) layers of 70 nm and 145 nm, respectively were desired. Titanium dioxide (TiO2) nanomaterial was deposited using sol-gel method on the channel which acts as a transducer. Surface functionalization on TiO2 thin film allowed an effective immobilization of anti-cardiac troponin I antibody to interact cardiac troponin I (cTnI). Binding events at each step was validated by X-ray photoelectron spectroscopy (XPS) analysis. Further, electrical characterization (Id-Vd) confirms the potentiality of FET-based biosensor to detect cTnI (represents acute myocardial infarction disease) with the concentration ranges from 10 MUg/ml down to 1 fg/ml. The sensitivity of 459.2 nA (g/ml)-1 and lower detection limit of 1 fg/ml were achieved at Vbg = -5 V and Vd = 5 V. The designed device demonstrates its ability to detect lower level of cTnI with pre-amplified electrical signal by back-gate biasing.

AB - In this study, calixarene was synthesized by using different functional groups as p-tert-butyl-Calix[4]arene ester and amides. Calixarene nanofibers were produced by electrospin coating. Protein immobilization onto the calixarene nanofibers was carried out with human serum albumin (HSA). The maximum amount of binding on produced three different calixarene nanofibers (DE, 2-AMP and 3-AMP) was compared by using a fluorescence technique for protein analysis. Result showed that maximum binding amount was found to be as 177.85 mg cm-2 for 3-AMP surface. The protein binding was also characterized by using SEM, TEM, AFM and FT-IR. From obtained results, calixarene-albumin nanofiber was also fabricated by spin coating using 3-AMP which has ability max binding of protein.

AB - Rice (Oryza sativa L.) is one of the major staple food crops of nearly two-third of the world's population. However, rice blast caused by fungus Pyricularia oryzae is generally considered the most serious disease of cultivated rice worldwide due to its extensive distribution and destructiveness under favourable climatic conditions. In this report, the combination between chitosan (CS) and silver (Ag), Ag@CS, was introduced for antifungal activity against Pyricularia oryzae extracted from blast-infected leaves. In detail, Ag@CS nanoparticles (NPs) were first synthesized and further mixed with Trihexad 700 WP (Tri), Ag@CS-Tri, against the fungus by agar diffusion method. The prepared Ag@CS-Tri NPs were characterized by Fourier transform infrared (FTIR), dynamic light scattering (DLS), transmission electron microscopy (TEM), X-ray diffraction (XRD), and thermogravimetric analysis (TGA). In aqueous condition, Ag@CS-Tri NPs were successfully prepared and existed as spherical NPs with particle size of 17.26 +/ 0.89 nm, which is an ideal size for their uptake into plant cells, indicating that the size of their parentally Ag@CS NPs is small enough to combine Tri, and their diameter is large enough to effectively penetrate the cellular membrane and kill fungi. More importantly, the antifungal property of Ag@CS-Tri NPs was significantly increased with inhibition zone around 25 nm compared with only around 12 nm of Ag@CS at the same concentration of Ag (2 ppm) and CS (4000 ppm). These results demonstrated that the synergistic effect of Tri and Ag@CS NPs can be a potential candidate with high antifungal activity for the use of antibiotics in agriculture. PMID- 29458581 TI - Transferrin Adsorbed on PEGylated Gold Nanoparticles and Its Relevance to Targeting Specificity. AB - Polyethylene glycol (PEG) has been frequently used for surface modification of nanoparticles (NPs) to reduce non-specific binding of proteins on NPs. The investigation of protein absorption on PEGylated nanoparticles is necessary. In the work, the conjugation of transferrin (Tf) to PEGylated AuNPs via adsorption or bonding was studied. The 13 nm AuNPs were coated with various molecular weight (300, 2000, 5000) carboxyl and methoxy PEG thiol. The presence of Tf on PEGylated AuNP was characterized by dynamic light scattering (DLS) and infrared spectroscopy (IR). The data of IR confirmed the presence of Tf on PEGylated AuNPs. The diameter decrease of PEGylated AuNPs after Tf adsorption was observed by DLS measurement, which is attributed to competitive adsorption between Tf and PEG molecules. These phenomena may be important to the preservation of Tf targeting specificity on PEGylated AuNPs.

AB - Compared to two-dimensional (2D) conditions, investigation on gene transfection in three-dimensional (3D) conditions is much less extensive. In this work, lamellar nano-hydroxyapatite (L-HAp) with and without magnetism were used as the vectors and gene transfection in 2D and 3D cell culture was carried out and compared. We found that the transfection efficiency in 3D conditions was much higher than 2D cell culture. Additionally, magnetism enhanced transfection efficiency under both 2D and 3D conditions. The findings presented in this study demonstrated that the magnetic L-HAp could be a promising vector in 3D gene transfection.

IMC) have been intercalated into the layered terbium hydroxide (LTbH) by anion exchange method. Chemical compositions, thermostability, morphology, luminescence property, release behaviors and cytotoxic effects have been investigated. The DS molecules may embed between layers with a bilayered arrangement and the IMC may correspond to a monolayered arrangement. The Tb3+ luminescence in DS-LTbH and IMC-LTbH composites were enhanced compared with LTbH precusor and the luminescence intensity increases with the deprotonation degree. Drug release was measured with HPLC, and LTbH showed sustained release behavior on both drugs. Further In Vitro evaluation were carried out on cancer cells. Cytotoxic effect of LTbH was observed with a sulforhodamine B colorimetric assay on a variety of cancer cell lines, which revealed that the LTbH showed little cytotoxic effect. Results indicate LTbH may offer a potential vehicle as an effective drug delivery system along with diagnostic integration.

AB - We report the design and synthesis of a novel chemosensor (Rh6G-Cin) rhodamine based indicator for selective detection of Zn2+ ion. Rh6G-Cin displayed high selectivity towards Zn2+ from various metal ions, including Ca2+, Ag+, Cd2+, Co2+, Cu2+, Al3+, Zn2+, Cr3+, Ba2+, Fe2+, Fe3+, Gd3+, Hg2+, Mg2+, Mn2+, Nd3+, Pb2+, Sr2+ and Ni2+, and the resultant complex is [Rh6G-Cin-Zn2+]. The obvious change from colorless to pink upon the addition of Zn2+ could make it a suitable "naked eye" indicator for Zn2+. More significantly, the sensor displayed a remarkable colorless to yellowish green fluorescence switch in the presence of Zn2+ ions. The ring-opening mechanism of the rhodamine spirolactam was induced by Zn2+ binding, and the 3:1 stoichiometric structure between Rh6G-Cin and Zn2+ was adequately supported by the Job's plot evaluation, optical titration and 1H NMR results.

AB - The potential of callus cultures and field-grown organs of pumpkin (Cucurbita maxima) for the biosynthesis of nanoparticles of the noble metals gold and silver has been investigated. Biosynthesis of AuNPs (gold nanoparticles) and AgNPs (silver nanoparticles) was obtained with flowers of C. maxima but not with pulp and seeds. With callus cultures established in MS-based medium the biogenesis of both AuNPs and AgNPs could be obtained. At 65 degrees C the biogenesis of AuNPs and AgNPs by callus extracts was enhanced. The AuNPs and AgNPs have been characterized by UV-visible spectroscopy, TEM, DLS and XRD. Well-dispersed nanoparticles, which exhibited a remarkable diversity in size and shape, could be visualized by TEM. Gold nanoparticles were found to be of various shapes, viz., rods, triangles, star-shaped particles, spheres, hexagons, bipyramids, discoid particles, nanotrapezoids, prisms, cuboids. Silver nanoparticles were also of diverse shapes, viz., discoid, spherical, elliptical, triangle-like, belt-like, rod-shaped forms and cuboids. EDX analysis indicated that the AuNPs and AgNPs had a high degree of purity. The surface charges of the generated AuNPs and AgNPs were highly negative as indicated by zeta potential measurements. The AuNPs and AgNPs exhibited remarkable stability in solution for more than four months. FTIR studies indicated that biomolecules in the callus extracts were associated with the biosynthesis and stabilisation of the nanoparticles. The synthesized AgNPs could catalyse degradation of methylene blue and exhibited anti-bacterial activity against E. coli DH5alpha. There is no earlier report of the biosynthesis of nanoparticles by this plant species. Callus cultures of Cucurbita maxima are effective alternative resources of biomass for synthesis of nanoparticles.

AB - We report the influence of Co1-xZnxFe2O4 nanoferrites for the photodegradation of organic pollutant present in the aqueous solution. A series of Co1-xZnxFe2O4 (x = 0.01, 0.03, 0.05 and 0.10) nanoferrites have been synthesized via a facile and economically viable coprecipitation technique and investigated the effect of zinc dopant in their structural, optical, electrical and magnetic properties. X-ray diffraction and Fourier Transform Infrared spectral studies reveal the spinel phase formation of the as-synthesized nanoferrites. Photoluminescence and UV visible spectral studies show the bandgap of nanoferrites increase from 2.47-2.67 eV and exhibited a blue shift in the band edge emission with respect to increase in Zn content. Phase transition of the samples from weak ferromagnetic to superparamagnetic nature has been observed by Vibrating Sample Magnetometer at room temperature. Furthermore, the Co1-xZnxFe2O4 was assessed for the degradation of Methylene Blue (MB) dye and the sample with Co1-0.10Zn0.10Fe2O4 showed better photocatalytic degradability of organic MB due to its enhanced adsorption in the visible region and the existence of lower concentration charge-carriers.

AB - Hierarchical ordered ZSM-5 zeolites were successfully synthesized by a template free hydrothermal treatment using rice joints ash as the source of silica. The formation of hierarchical ordered ZSM-5 zeolites and its physicochemical properties were investigated systematically. The mineralogical phases, morphology, surface area and porosity, acidity and thermal stability of the synthesized hierarchical materials were investigated using XRD, FT-IR, HR-SEM, N2 adsorption-desorption (BET) analysis, NH3-TPD and TGA/DTA analysis. The excellent catalytic activity of hierarchical ordered ZSM-5 zeolites (150 degrees C) was revealed in the selective oxidation of toluene to the corresponding benzaldehyde with 82% conversion and 94% selectivity. The material was evaluated for the oxidation of toluene in the presence of H2O2 as the oxidizing agent and 1,4 dioxane solvent. The obtained results noted that the material was highly active, stable and can be recycled at least four times without a loss of catalytic efficiency. The crystallization was carried out in an autoclave for 5 days maintained at a temperature of 150 degrees C for the transformation of RJA into hierarchical ZSM-5 zeolite structure as well as to achieve high crystallinity.

AB - Carbon nanotubes (CNTs) are still receiving much attention in bio-sensing applications due to their remarkable properties. In this present research work, fibre-like carbon nanotubes (f-CNTs) were successfully fabricated over copper molybdenum (Cu-Mo) substituted alumina nanoparticles at atmospheric pressure by chemical vapor deposition (CVD) technique and effectively employed as a neurotransmitter dopamine (DA) sensor. The obtained product was purified and structurally characterized by various techniques such as, field emission scanning electron microscope (FESEM), energy dispersive X-ray spectroscopy (EDX), Raman spectroscopy, high resolution transmission electron microscope (HRTEM) and X-ray photoelectron spectroscopy (XPS) analysis. Structural characterization, which reveals the material contains fibre-like multi walled carbon nanotubes with graphene layers having diameter in the range of 10-20 nm and 200-300 nm inner and outer, respectively and has certain crystallinity. The weight percentages of Cu, Mo in Alumina catalyst, reaction temperature, acetylene flow rate and reaction time have been optimised to yield maximum of carbon product. Electrochemical properties of the material towards DA sensing were studied by cyclic voltammetry (CV), and diffuse pulse voltammetry (DPV) techniques. The sensor exhibits linear relationship among the peak current and DA concentration from 8 to 45 MUM with detection limit of 5.3 MUM (S/N = 3). The presence of structural analogues of DA has no deleterious effect on the DA anodic peak current.

AB - Asymmetric Cu to In/Sn bonding structure with Ni ultrathin buffer layer (UBL) on Cu side is investigated in this research. The usage of Ni UBL slows down intermetallic compound (IMC) formation during bonding. Asymmetric structure can separate electrical isolation and solder process to avoid interaction, which can prevent IMC formation during polymer curing. A well-bonded asymmetric structure can be achieved with submicron solder by 150 degrees C bonding for 15 min. The structure shows the potential for low temperature hybrid bonding technology in high-density three-dimensional (3D) integration.

AB - In this paper, authors report the synthesis of nanocrystalline hierarchical zeolite ZSM-5 and its application as a heterogeneous catalyst in the alkylation of phenol with cyclohexene. The catalyst was synthesized by vacuum-concentration coupled hydrothermal technique in the presence of two templates. This synthetic route could successfully introduce pores of higher hierarchy in the zeolite ZSM-5 structure. Hierarchical ZSM-5 could catalyse effectively the industrially important reaction of cyclohexene with phenol. We ascribe the high efficiency of the catalyst to its conducive structural features such as nanoscale size, high surface area, presence of hierarchy of pores and existence of Lewis sites along with Bronsted acid sites. The effect of various reaction parameters like duration, catalyst amount, reactant mole ratio and temperature were assessed. Under optimum reaction conditions, the catalyst showed up to 65% selectivity towards the major product, cyclohexyl phenyl ether. There was no discernible decline in percent conversion or selectivity even when the catalyst was re-used for up to four runs. Kinetic studies were done through regression analysis and a mechanistic route based on LHHW model was suggested.

AB - In this study, 2-mercapto-1,3,4-thiadiazole (2-MT) self-assembled monolayer (SAM) was formed on copper electrode surface and the resulting 2-MT SAM on copper has been characterized using surface analytical techniques such as Fourier transform infrared (FT-IR) spectroscopy, energy dispersive X-ray (EDX) analysis, atomic force microscopy (AFM) and contact angle measurement (CA). The existence of N and S in the EDX and FT-IR analysis showed that 2-MT molecules were self-assembled on the copper through N and S by chemisorption which indicates the formation of 2-MT SAM on copper surface. Corrosion protection performance of 2-MT SAM on copper was investigated using potentiodynamic polarization studies (PDS), cyclic voltammetry (CV) and scanning electron microscopy (SEM), respectively. Analysis of both electrochemical and SEM analysis results revealed excellent corrosion protection for the copper substrate.

AB - In present work, reduced graphene oxide hydrogels (RGOHs) with three-dimensional (3D) porous structure are prepared through chemical reduction method by using aminourea (NRGOHs) and aminothiourea (NSRGOHs) as reductants. The as-prepared RGOHs are considered not only as promising electrode materials for supercapacitors, but also the doping of nitrogen (aminourea, NRGOHs) or nitrogen/sulfur (aminothiourea, NSRGOHs) can improve electrochemical performance through faradaic pseudocapacitance. The optimized samples have been prepared by controlling the mass ratios of graphene oxide (GO) to aminourea or aminothiourea to be 1:1, 1:2 and 1:5, respectively. With adding different amounts of aminourea or aminothiourea, the obtained RGOHs exhibited different electrochemical performance in supercapacitors. With increasing the dosage of the reductants, the RGOHs revealed better specific capacitances. Moreover, NSRGOHs with nitrogen, sulfur-codoping exhibited better capacitance performance than that of NRGOHs with only nitrogen-doping. NSRGOHs showed excellent capacitive performance with a very high specific capacitance up to 232.2, 323.3 and 345.6 F g-1 at 0.2 A g-1, while NRGOHs showed capacitive performance with specific capacitance up to 220.6, 306.5 and 332.7 F g-1 at 0.2 A g-1. This provides a strategy to improve the capacitive properties of RGOHs significantly by controlling different doping the materials.

AB - Intense yellow-white NaLa(MoO4)2: Dy3+ phosphors co-doped with Li+ ions have been successfully synthesized via facile sol-gel combustion approach. The dependence of the crystal structure and crystallinity, particle morphology, photoluminescence property, fluorescent lifetime and absolute quantum efficiency of the as-prepared phosphors has been investigated. Stable yellow-white emission from 440 nm to 600 nm and higher absolute quantum efficiency were studied on Dy3+ doped NaLa(MoO4)2, Dy3+ and Li+ co-doped NaLa(MoO4)2, respectively. Surprisingly, only a small amount of Li+ can lead to a remarkable increase of the PL intensity and the quantum efficiency. Especially, along with 0.75 mol% Li+ ions induced in the NaLa(MoO4)2: Dy3+ phosphors, the absolute quantum efficiency increased from 13.8% to 22%, and the possible mechanism has been deeply discussed. Outstanding luminescence properties have certified that NaLa(MoO4)2: Dy3+, Li+ phosphors are promising candidates as new yellow-white components for optical devices.

AB - Nanoparticles of Li, Mg and Sr doped and undoped zinc oxide was prepared by simple precipitation method. The structural, optical, and magnetic properties of the samples were investigated by the Powder X-ray Diffraction (XRD), Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM), Fourier Transform Infrared (FTIR) spectroscopy, Ultra-violet Visible spectroscopy (UV vis) spectra, Photoluminescence (PL) and Vibrational Sample Magnetometer (VSM). The Powder X-ray diffraction data confirm the formation of hexagonal wurtzite structure of all doped and undoped ZnO. The SEM photograph reveals that the pores availability and particles size in the range of 10 nm-50 nm. FTIR and UV-Visible spectra results confirm the incorporation of the dopant into the ZnO lattice nanostructure. The UV-Visible spectra indicate that the shift of blue region (lower wavelength) due to bandgap widening. Photoluminescence intensity varies with doping due to the increase of oxygen vacancies in prepared ZnO. The pure ZnO exist paramagnetic while doped (Li, Mg and Sr) ZnO exist ferromagnetic property.

AB - This paper demonstrates the effectiveness of using detonation nanodiamonds (DNDs) for detecting phenol in aqueous medium. The study has shown that the catalytic effect of DNDs in the oxidative azo coupling reaction (phenol-4-aminoantipyrine hydrogen peroxide) is produced by trace amounts of iron and copper ions adsorbed on the surface of nanoparticles. The effectiveness of DNDs as a catalyst is determined by the amounts of these adsorbates and can be enhanced by a factor of two by additional adsorption of these ions onto the nanoparticles. A rise in the temperature of the DND-catalyzed azo coupling reaction leads to a considerable (4.5-fold) increase in the reaction product yield. DNDs used to detect phenol in aqueous medium enable a linear increase in the yield of the product of the azo coupling reaction at concentrations of the analyte of between 0.05 and 10 MUg/ml. The study demonstrates that DNDs can be reused to detect phenol in water samples.

The XRD spectrum confirms the presence of both tetragonal rutile SnO2 and rhombohedral corundum Cr2O3 structure. Further investigation into the gas sensing performances of the prepared Cr2O3-SnO2 nanocomposites exhibited an enhanced sensitivity towards VOPs such as isopropanol, acetone, ethanol and formaldehyde. Especially, isopropanol vapor sensor shows excellent sensitivity at an operating temperature of 100 degrees C. The highest sensitivity for Cr2O3-SnO2 heterojunction nanocomposites indicate that these materials can be a good candidate for the production of high performance isopropanol sensors.

AB - Nitrogen-doped graphene oxide (NGO) nanosheets were prepared via a facile one-pot modified Hummer's approach at low temperatures using graphite powder and flakes as starting materials in the presence of a nitrogen precursor. It was found that the morphology, structure, composition and surface chemistry of the NGO nanosheets depended on the nature of the graphite precursor used. GO nanosheets doped with nitrogen atoms exhibited a unique structure with few thin layers and wrinkled sheets, high porosity and structural defects. NGO sheets made from graphite powder (NGOp) exhibited excellent thermal stability and remarkably high surface area (up to 240.53 m2 .g-1) compared to NGO sheets made from graphite flakes (NGOf) which degraded at low temperatures and had an average surface area of 24.70 m2 .g-1. NGOf sheets had a size range of 850 to 2200 nm while NGOp sheets demonstrated obviously small sizes (460-1600 nm) even when exposed to different pH conditions. The NGO nanosheets exhibited negatively charged surfaces in a wide pH range (1 to 12) and were found to be stable above pH 6. In addition, graphite flakes were found to be more suitable for the production of NGO as they produced high N-doping levels (0.65 to 1.29 at.%) compared to graphite powders (0.30 to 0.35 at.%). This study further demonstrates that by adjusting the amount of N source in the host GO, one can tailor its thermal stability, surface morphology, surface chemistry and surface area.

AB - A series of Fe100-xDyx thin films with the concentration range x = 6 to 35 were fabricated by dc magnetron sputtering process. X-ray diffraction and TEM studies revealed that films have separate Fe and Dy nanograins and that there is no intermixing of Fe and Dy thus forming nanogranular films. This unmixed behaviour in our thin films is very different from the bulk Fe-Dy alloys where several stoichiometric compounds can be formed. Magnetic properties of the films have been systematically studied. The contribution to the total magnetization is due to the Fe grains and the Dy grains are paramagnetic down to 4 K. The saturation magnetization of all the samples is significantly lower than that of bulk Fe due to the existence of superparamagnetic Fe grains. Upon increasing x, the in-plane magnetic anisotropy is found to decrease and the samples become isotropic. The zero field cooled and field cooled magnetization measurements also confirmed the presence of the superparamagnetic Fe grains.

AB - CsxWO3/TiO2 composites with different contents of CsxWO3 were successfully synthesized in this study by a facile hydrothermal process. CsxWO3/TiO2 composites were characterized by XRD, Raman, UV-visible diffuse reflectance spectra (DRS), photoluminescence spectra (PL) and SEM. TiO2 nanoparticles were distributed uniformly on the surface of the CsxWO3 microsphere in the prepared CsxWO3/TiO2 composites, and they formed heterojunctions with CsxWO3. The effect of CsxWO3 on the photoactivities of composites was investigated via DRS and PL. All CsxWO3/TiO2 catalysts showed enhanced photocatalytic activity for degrading rhodamine B under visible light irradiation. The 50% CsxWO3/TiO2 sample showed the best photocatalytic activity and its kinetic constant was 20 times larger than that of TiO2. The possible photocatalytic mechanism is also discussed from the trapping experiments of active species. The improved photocatalytic activity for the CsxWO3/TiO2 catalyst may be attributed to the synergetic effect between CsxWO3 microspheres and TiO2 nanoparticles. This novel photocatalyst can be used to degrade environmental pollutants in the future.

AB - Elimination of pollutants from water is one of the greatest challenges in resolving global environmental issues. Herein, we report a high-surface-area mesoporous g-C3N4 nanosheet with remarkable high adsorption capacity and photocatalytic performance, which is prepared through directly polycondensation of urea followed by a consecutive one-step thermal exfoliation strategy. This one pot method to prepare mesoporous g-C3N4 nanosheet is facile and rapid in comparison with others. The superior adsorption capacity of the fabricated mesoporous g-C3N4 nanostructures is demonstrated by a model organic pollutant methylene blue (MB), which is up to 72.2 mg/g, about 6 times as that of the largest value of various g-C3N4 adsorbents reported so far. Moreover, this kind of porous g-C3N4 nanosheet exhibits high photocatalytic activity to MB and phenol degradation. Particularly, the regenerated samples show excellent performance of pollutant removal after consecutive adsorption/degradation cycles. Therefore, this mesoporous g-C3N4 nanosheet may be an attractive robust metal-free material with great promise for organic pollutant elimination. PMID- 29458604 TI - Measuring the Acoustic Release of a Chemotherapeutic Agent from Folate-Targeted Polymeric Micelles. AB - In this paper, we compare the use of Bayesian filters for the estimation of release and re-encapsulation rates of a chemotherapeutic agent (namely Doxorubicin) from nanocarriers in an acoustically activated drug release system. The study is implemented using an advanced kinetic model that takes into account cavitation events causing the antineoplastic agent's release from polymeric micelles upon exposure to ultrasound. This model is an improvement over the previous representations of acoustic release that used simple zero-, first- and second-order release and re-encapsulation kinetics to study acoustically triggered drug release from polymeric micelles. The new model incorporates drug release and micellar reassembly events caused by cavitation allowing for the controlled release of chemotherapeutics specially and temporally. Different Bayesian estimators are tested for this purpose including Kalman filters (KF), Extended Kalman filters (EKF), Particle filters (PF), and multi-model KF and EKF. Simulated and experimental results are used to verify the performance of the above-mentioned estimators. The proposed methods demonstrate the utility and high accuracy of using estimation methods in modeling this drug delivery technique. The results show that, in both cases (linear and non-linear dynamics), the modeling errors are expensive but can be minimized using a multi-model approach. In addition, particle filters are more flexible filters that perform reasonably well compared to the other two filters. The study improved the accuracy of the kinetic models used to capture acoustically activated drug release from polymeric micelles, which may in turn help in designing hardware and software capable of precisely controlling the delivered amount of chemotherapeutics to cancerous tissue.

In this study, the adsorption of Cr(VI) was analyzed using activated carbon (AC) and biochar (BSC) made from sewage sludge. BSC materials were synthesized using zinc chloride as an activator coupled with carbonized sewage sludge. Specific surface area, pore size distribution, and pore volume were determined by measuring nitrogen adsorption-desorption (BET). BSC morphology was measured using field-emission scanning electron microscopy (SEM) with energy dispersive X-ray spectroscopy (EDS). Results showed that the surface area and average pore volume of the BSC were 490 m2 g-1 and 0.8 cm3 g-1, respectively. SEM results revealed that BSC had uniform pore size. Effects of varying the initial Cr(VI) concentrations, pH values, and dosages of BSC on adsorption performance were also determined. Results showed that the maximum removal efficiency of Cr(VI) was above 99%, and adsorption capacity of 50% ZnCl2-BSC was 677 mg g-1.

Different methods are proposed to optimize its performance from viewpoints of process and structure. BSG in 3D NAND is a novel device structure with two connected transistors: one is horizontal MOSFET (regarded as convention MOSFET) and one is vertical MOSFET (regarded as GAA transistor).

AB - Characterization of bio-nano interface is crucial for developing safer and more efficient nanoparticles in nanomedical application. PEGylation is commonly used in nanocarrier for drug delivery, as it confers nanoparticles good stability, stealth effect and better targeting specificity compared with those without PEGylation. However, the protein binding state on PEGylated AuNP is still limited known. In present work, we prepared 13 nm AuNPs and then PEGylated them with thiol PEG methoxy. Lysozyme is selected as a model protein and to investigate the interactions on protein-PEGylated/AuNP interface. The thermal unfolding processes of lysozyme in absence and presence of PEGylated AuNP were measured by synchrotron radiation based circular dichroism (SRCD), dynamic light scattering (DLS) and infrared spectroscopy (IR). The results suggest that in terms of secondary structural changes, alpha helix content is decreased, while beta sheet content is increased, and thus the adsorbed lysozyme may be present in PEG layer. PMID- 29458609 TI - Prediction of Sliding Friction Coefficient Based on a Novel Hybrid Molecular Mechanical Model. AB - Sliding friction is a complex phenomenon which arises from the mechanical and molecular interactions of asperities when examined in a microscale. To reveal and further understand the effects of micro scaled mechanical and molecular components of friction coefficient on overall frictional behavior, a hybrid molecular-mechanical model is developed to investigate the effects of main factors, including different loads and surface roughness values, on the sliding friction coefficient in a boundary lubrication condition. Numerical modelling was conducted using a deterministic contact model and based on the molecular mechanical theory of friction. In the contact model, with given external loads and surface topographies, the pressure distribution, real contact area, and elastic/plastic deformation of each single asperity contact were calculated. Then asperity friction coefficient was predicted by the sum of mechanical and molecular components of friction coefficient. The mechanical component was mainly determined by the contact width and elastic/plastic deformation, and the molecular component was estimated as a function of the contact area and interfacial shear stress. Numerical results were compared with experimental results and a good agreement was obtained. The model was then used to predict friction coefficients in different operating and surface conditions. Numerical results explain why applied load has a minimum effect on the friction coefficients. They also provide insight into the effect of surface roughness on the mechanical and molecular components of friction coefficients. It is revealed that the mechanical component dominates the friction coefficient when the surface roughness is large (Rq > 0.2 MUm), while the friction coefficient is mainly determined by the molecular component when the surface is relatively smooth (Rq < 0.2 MUm). Furthermore, optimal roughness values for minimizing the friction coefficient are recommended.

AB - Pt/CNTs were synthesized with an ethylene glycol reduction method, and the effects of carboxyl functionalization, ultrasonic power and the concentration of chloroplatinic acid on the catalytic activity of Pt/CNTs were investigated. The optimal performance of the Pt/CNTs catalyst was obtained when the ultrasonic power was 300 W and the concentration of chloroplatinic acid was 40 mg/mL. The durability and stability of the Pt/CNTs catalyst were considerably better compared to Pt/C, as shown by cyclic voltammetry measurement results. The trans fatty acids content of the obtained hydrogenated soybean oil (IV: 108.4 gl2/100 g oil) using Pt/CNTs as the cathode catalyst in a solid polymer electrolyte reactor was only 1.49%. The IV of hydrogenated soybean oil obtained using CNTs as carrier with Pt loading 0.1 mg/cm2 (IV: 108.4 gl2/100 g oil) was lower than carbon with a Pt loading of 0.8 mg/cm2 (IV: 109.9 gl2/100 g oil). Thus, to achive the same IV, the usage of Pt was much less when carbon nanotubes were selected as catalyst carrier compared to traditional carbon carrier. The changes of fatty acid components and the hydrogenated selectivity of octadecenoic acid were also discussed.

The morphology, microstructure and optical properties of the as-prepared Bi2MoO6-BiOCl nanocomposites were characterized using transmission electron microscopy (TEM), X-ray diffraction (XRD) and UV-Vis diffuse reflection spectroscopy (DRS). A noteworthy enhancement in the visible light-responsive photocatalytic degradation of RhB was observed over the Bi2MoO6 BiOCl nanocomposites compared to its individual components. The enhanced photocatalytic performance of Bi2MoO6-BiOCl nanocomposites could be attributed to the heterojunction interface in the composite, which can both efficiently separate photogenerated electron-hole pairs and also restrain the recombination of photoinduced charges.

The SLN were characterized by Differential Scanning Calorimetry (DSC), X ray Diffraction (XRD), Small Angle X-ray Diffraction (SAXS), in vitro release, transmission electron microscopy, and polarized light microscopy. Evaluation of cell viability was performed in two cell cultures: MCF-7 (human breast cancer) and 4T1 (murine breast cancer). The SLN showed a size in the range of 128 nm, negative zeta potential, DOX encapsulation efficiency (EE) of 99%, and drug loading (DL) of 66 mg/g. Characterization of the formulation by DSC, XRD, and SAXS revealed the presence of DOX inside the nanoparticles of SLN and suggested increased expulsion/release of this drug when associated with SC. The release profiles revealed that the SLN-DOX-SC showed controlled release of DOX at pH 7.4 with enhanced drug release at low pH, useful for cancer treatment. The SLN-DOX-SC demonstrated to be more effective than the free DOX against 4T1 cells. So, the developed SLN efficiently encapsulate DOX and SC and show good potential as an alternative for cancer treatment.

AB - In this work, porous electrospun polylactic acid (PLA) fibers with high specific surface area and excellent biodegradability were examined as the support of titanium dioxide (TiO2) nanoparticles (NPs). The deposition of TiO2 NPs on porous electrospun PLA fibrous substrates was accomplished through the hydrolysis of titanium tetra isopropoxide (TTIP) under ultrasonic irradiation, and the effects of the TTIP concentrations on structure and property of composite fibers was also investigated. The prepared TiO2-deposited PLA composite fibers were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), High-resolution transmission electron microscopy (HRTEM), Brunauer-Emmett-Teller (BET) and thermogravimetric analyzer (TGA). The results indicated that the anatase TiO2 NPs with an average size of about several tens of nanometers to 200 nm were successfully loaded onto surface of porous PLA fibrous substrates. Meanwhile, the TiO2 NPs liked a "double-edged sword," overfull deposition of TiO2 NPs had negative effect on the properties of composite fibers. Under the optimized condition, the TiO2 NPs deposited dispersedly on the surface of PLA fibers without severe agglomeration and this structure performed with a high specific surface area of 64.8 m2/g, which was 5 times as large as pure PLA nanofibers (12.9 m2/g). In addition, the prepared TiO2-loaded composite fibers showed satisfactory removal efficiency on MB, the MB concentration decreased about 75%, which was remarkably higher than that of pure PLA fibers. Compared with powdery TiO2, TiO2-loaded composite fibers showed considerable photocatalytic activity, as well as easier operation, confirming this hybrid composite fibers was suitable for the easier operated application of TiO2.

AB - The preparation, characterization and application of chitosan (CS) based electrospun nanofiber membrane for the adsorptive removal of Cu(II) from water were systematically investigated. Homogeneous, porous polyvinyl alcohol (PVA)/CS nanofiber membrane with amorphous structure, and average fiber diameter of 49 nm was successfully fabricated. The adsorption of Cu(II) onto the positively charged PVA/CS nanofiber membrane (pH < 6) was due to chemisorption rather than electrostatic adherence, and was highly pH-dependent. The adsorption equilibrium of Cu(II) by the PVA/CS nanofiber was established within 120 min, which was much faster than that by CS beads, and the adsorption kinetics followed pseudo-second order model well (r 2 > 0.995). The adsorption isotherm data were well fitted with Langmuir model, and the maximum Cu(II) adsorption capacity of PVA/CS nanofiber membrane was 90.3 mg.g-1, which was much higher than that of CS beads. The adsorbed Cu(II) formed strong inner-sphere complex with the adsorbent. Coexisting cations of iron, lead, cadmium, nickel, calcium, and magnesium have insignificant effect on the Cu(II) adsorption, indicating the adsorbent has good selectivity for Cu(II) adsorption. FTIR and XPS analysis reveal amine, hydroxyl and ether groups are responsible for the Cu(II) adsorption. This work demonstrates the electrospun PVA/CS nanofiber membrane is a promising adsorbent for heavy metal removals.

AB - In this paper, a sol-gel derived mesoporous polymeric carbon nitride has been investigated as a photocatalyst for CO2 photocatalytic reduction. Noble-metal Pt nanoparticles were deposited on carbon nitride (sg-CN) in order to investigate the performance of both Pt-sg-CN and sg-CN for photocatalytic CO2 reduction. Physicochemical properties of prepared nanocomposites were comprehensively characterized by using powder XRD, N2 physisorption, UV-Vis DRS, ICP-AES, FTIR, solid-state NMR, SEM, TEM and photoelectrochemical measurements. Compared with pure sg-CN, the resulting Pt-loaded sg-CN (Pt-sg-CN) exhibited significant improvement on the CO2 photocatalytic reduction to CH4 in the presence of water vapor at ambient condition under UV irradiation. 1.5 wt.% Pt-loaded sg-CN (Pt-sg CN) photocatalyst formed the highest methane yield of 13.9 MUmol/gcat. after 18 h of light irradiation, which was almost 2 times and 32 times improvement in comparison to pure sg-CN and commercial TiO2 Evonik P25, respectively. The substantial photocatalytic activity of Pt-sg-CN photocatalyst for the yield product of the CO2 photocatalytic reduction was attributed to the efficient interfacial transfer of photogenerated electrons from sg-CN to Pt due to the lower Fermi level of Pt in the Pt-sg-CN hybrid heterojunctions as also evidenced by photo-electrochemical measurements. This resulted in the reduction of electron hole pairs recombination for effective spatial charge separation, consequently increasing the photocatalytic efficiency.

AB - We have developed a facile, efficient, economic, and green method to fabricate uniform MFe2O4 (M Co, Ni, Cu) hollow spheres by using polyacrylamide (PAM) as an additive agent. The as-obtained three types of hollow ferrites are employed to catalyze the reductive transformation of nitrophenols to aminophenols, which exhibit excellent catalytic activity. The kinetics of the catalytic reaction follows the quasi-first order reaction and its rate constant (kapp) values for CoFe2O4, NiFe2O4 and CuFe2O4 are calculated to be 1.62, 11.74 and 37.28 min-1, respectively. These data are higher than those former reports which using similar reactions catalyzed by different nanocatalysts. Among the three catalysts, NiFe2O4 and CuFe2O4 can be successfully reused for at least six consecutive cycles and have a stable conversion efficiency of about 100%, while CoFe2O4 is catalytically inactive after three cycles. The superiority of the catalytic reduction of NiFe2O4 and CuFe2O4 may be due to their soft magnetic properties as well as their better separation efficiency of the electron-hole pairs. Thus it is expected that these two recyclable hollow ferrites will be used commercially in the treatment of aromatic nitro compounds in industrial wastewater.

AB - Nitrogen doped beta-Ga2O3 nanostructures were synthesized using a simple one-step aqueous approach. The structure and morphology of the nanostructures were characterized. Both the GaOOH precursor and beta-Ga2O3 nanostructures showed the rod-like morphology. Meanwhile, the beta-Ga2O3 nanostructures were doped with nitrogen, which was proved by X-ray photoelectron spectroscopy (XPS), photoluminescence (PL) and cathodoluminescence (CL). The results showed nitrogen doped one-dimensional beta-Ga2O3 nanostructures were achieved by in situ doping while maintaining the morphology. Meanwhile, as a straightforward method, the excellent luminescence properties are suitable for application in white-LED phosphors and novel optoelectronic devices.

AB - Titanium dioxide (TiO2) has been regarded as an efficient photocatalyst for degradation of environmental pollutants. However, recovery of TiO2 nanoparticles from suspension limits its practical application. Herein, we reported a novel highly transparent poly(vinyl alcohol)(PVA)/TiO2 photocatalytic film via in-situ growth and solution casting method. TiO2 nanoparticles with average size of 10 nm were uniformly dispersed in transparent PVA matrix. The photocatalytic performance was investigated by photodegradation of methyl orange (MO) aqueous solution under solar light irradiation. PVA/TiO2 photocatalytic film exhibited remarkably high photocatalytic activity and excellent recyclable properties during multi-cycle use. PVA not only acted as a transparent supports for TiO2, but also worked as an efficient holes scavenger. The hydroxyl groups on PVA chains played a key role in separation of photo-generated electrons and holes, thus increased the photodegradation rate of MO. This work gives an easy and reliable way for polymer/TiO2 nanocomposites in practical environmental applications. PMID- 29458623 TI - Effect of Fluorine Diffusion on Amorphous-InGaZnO-Based Thin-Film Transistors. AB - This study investigated the effect of fluorine (F) diffusion from a fluorinated siliconnitride passivation layer (SiNX:F-Pa) into amorphous-InGaZnO-based thin film transistors (a-IGZO TFTs). The results of thermal desorption spectroscopy and secondary ion mass spectrometry revealed that F was introduced into the SiOX etch-stopper layer (SiOX-ES) during the deposition of a SiNX:F-Pa, and did not originate from desorption of Si-F bonds; and that long annealing times enhanced F diffusion from the SiOX-ES layer to the a-IGZO channel. Improvements to the performance and threshold-voltage (Vth) negative shift of IGZO TFTs were achieved when annealing time increased from 1 h to 3 h; and capacitance-voltage results indicated that F acted as a shallow donor near the source side in a-IGZO and induced the negative Vth shift. In addition, it was found that when IGZO TFTs with SiNX:F-Pa were annealed 4 h, a low-resistance region was formed at the backchannel of the TFT, leading to a drastic negative Vth shift.

AB - The Co-Fe prussian blue coordination polymer modified Silicon nanowires array (SiNW@CoHCF array) exhibits promising behavior in photoelectrochemical (PEC) water oxidation, giving rise to a largely enhanced photocurrent density and stability, much superior to those of SiNW-based photoanodes. The CoHCF shell as effective co-catalyst increases the reaction kinetics, thus depressing the charge recombination rate, as well as protects SiNWs array photoanode from photocorrosion. It is found that the CoHCF significantly decreases the charge transfer impedance (Rct), which means that the CoHCF facilitates majority transport and collection. These advantages may account for the performance enhancement. PMID- 29458625 TI - Facile Synthesis of Graphene Encapsulated Co2SnO4 Nanoparticles as Enhanced Anode Materials for Lithium-Ion Batteries. AB - A graphene encapsulated Co2SnO4 nanoparticles (Co2SnO4 NPs@rGO) was synthesized via the analogous mechanism of electrostatic interactions followed by thermal treatment. The Co2SnO4 NPs were uniformly encapsulated in the graphene sheets. As an anode material for rechargeable lithium batteries Co2SnO4 NPs@rGO exhibits enhanced cyclability and rate performance compared with free Co2SnO4 NPs. Even after 200 cycles, it still delivered large reversible capacity of 1037.9 mA h g-1 at 200 mA g-1. The excellent electrochemical performance should be associated with the uniform encapsulation of Co2SnO4 NPs by graphene sheets, which could not only effectively buffer the volume expansion and prevent the aggregation of the Co2SnO4 NPs but maintain good electrical conductivity of the whole electrode during the discharge/charge process.

AB - A simple technique of two-step growth was employed to fabricate homogeneous ZnO core/shell nanorod arrays which were composed of ZnO nanodisk shell layer on the surface of ZnO nanorod arrays. The ultraviolet (UV) response characteristics of the device were measured. The homogeneous ZnO core/shell photodetector had remarkably enhanced response and recovery speed compared with pure ZnO nanorod arrays. It indicated that surface homogeneous coating can be an alternative method to enhance the response and recovery properties of the ZnO nanorod array photodetectors. PMID- 29458627 TI - Proton-Conducting Polymer Membrane Consisting of Cross-Linked Poly(2-hydroxyethyl methacrylate) with Nafion(r) for Fuel Cell Application. AB - To increase the water retention and proton-conducting ability of Nafion(r), we prepared a cross-linked polymer consisting of poly(2-hydroxyethyl methacrylate) (pHEMA) and Nafion(r). pHEMA was chosen as a cross-linking polymer because it produces a water-insoluble but water-swellable polymer. Although it is hydrophobic, its water-swellable characteristic means that water will not be excluded from the polymer. Introduction of pHEMA into Nafion(r) prevents polymer solubility and provides structural stability and rigidity, which should in turn reduce the methanol permeability. Moreover, convenient permeability of pHEMA to cations makes it a good candidate for a hydrocarbon proton-conducting polymer tuned with Nafion(r). PMID- 29458628 TI - Size-Strain Analysis of Iron-Excess Mn-Zn Ferrite Nanoparticles Using Synchrotron Diffraction and Its Correlation with Magnetic Saturation and Isoelectric pH. AB - Iron-excess Mn-Zn ferrite nanoparticles were prepared by coprecipitation with sodium hydroxide (NaOH) at different concentrations (0.1, 0.2, 0.5 and 1.0 mol/L). The results of X-ray diffraction (XRD) analysis using Whole Powder Pattern Modeling (WPPM) showed that higher concentrations of NaOH promote crystallite growth and broader dispersion in crystallite sizes. Energy dispersive X-ray spectroscopy indicates that zinc loss is noticeable when [NaOH] >= 0.2 mol/L. XRD revealed also a significant less-crystalline phase contribution alongside the main peaks of the nanocrystalline cubic spinel ferrite phase. The less-crystalline fraction is lower for the ferrite obtained with 0.2 mol/L of NaOH, being about 50% and more than 70% for the other samples. Despite of the less-crystalline fraction and the excess of iron, no secondary phases were detected. The Warren curves showed that the concentration of NaOH significantly influences the microstrain in the crystallites, being smaller for the sample obtained with NaOH at 0.2 mol/L. The sample prepared with this condition presented the better properties to be used as magnetic tracer in clinical diagnoses combining small mean crystallite size, low microstrain, which resulted in materials with higher magnetic saturation and high surface charge under blood pH.

AB - In view of their super capacity of adsorbing microbial, the carbon nanotubes (CNTs) were used as the carriers for in situ synthesizing well-dispersed and small-sized silver nanodots (AgND), to prepare a new type of antibacterial agent with remarkably improved activity. Polyethyleneimine (PEI) was introduced as a linkage for guaranteeing the as-generated AgND to be anchored onto the CNTs and to prevent them from agglomeration. The obtained hybridizing materials were characterized by transmission electron microscopy, X-ray diffraction and X-ray photoelectron spectroscopy, and the results showed that the AgND with an average size of 2.6 nm were uniformly loaded on surfaces of CNTs. There existed special interactions between silver atoms and CNTs. The antibacterial activities of the as-prepared hybrids against Escherichia coli were evaluated by disk diffusion assay method and minimal inhibitory concentration measurements. The results showed that the as-prepared hybrids displayed a remarkable improvement in antibacterial activity as compared to CNTs, acidified-CNTs and even the identical silver amount of AgNO3 solution, which was mainly attributed to the small size of AgND and the hybridizing effect between AgND and CNTs. PMID- 29458630 TI - A Mesopore-Dependent Catalytic Cracking of n-Hexane Over Mesoporous Nanostructured ZSM-5. AB - Herein, pore size, crystalinity, and Si/Al ratio of mesoporous ZSM-5 (MFI) nanocrystals was controlled by synthesis parameters, such as surfactant concentration ([3-(trimethoxysilyl)propyl] hexa-decyl dimethyl ammonium chloride), sodium hydroxide concentrations, synthesis temperature and time. The morphology, surface structure and composition of the MFI particles was systematically investigated. More notably, the mesopore-dependent catalytic activity of ZSM-5 was evaluated by studying the cracking of n-hexane. The findings suggest the porosity has pronounced impact on the catalytic activity, selectivity and stability of ZSM-5 nanocrystals. Critical surface attributes such as nature of acid sites (Bronsted and Lewis), concentration, and strength are obtained by the infrared study of adsorbed probe molecules (pyridine) and the temperature programmed desorption. In spite of being weaker in Si/Al ratio or acidic strength, mesoporous catalysts showed more stable and efficient cracking of n-hexane suggesting that acidity seems not the predominant factor operative in the activity, selectivity and stability.

AB - Highly water-dispersible magnetic nanoparticles were synthesized by convenient electrochemical techniques using a continuous flow reactor. The surface properties of the magnetic nanoparticles (MNPs) were modified with hydrophilic organic ligands during the electrochemical synthesis process to control the degree of dispersion in water. The kind of hydrophilic low-molecular weight polymers or surfactants influenced the sizes of the particles ranged between 25 40 nm (in diameter) and their size distribution. Chitosan-modified MNPs exhibited the most uniform particle size distribution among the MNPs synthesized in this study as well as excellent dispersion stability and magnetic properties in water after the crosslinking of the amino groups in chitosan. Especially, the dispersion stability of the MNPs in water was systematically investigated via a light scattering analysis.

AB - In this paper, zeolite supported-nano TiO2 photocatalytic composites were synthesized by an easily-operated solid diffusion process, in which zeolite was used as the support matrix. And the microstructures, morphologies and photocatalytic properties of the zeolite supported-nano TiO2 composites were characterized and analyzed by scanning and transmission electron microscopy, X ray photoelectron spectroscopy, UV-visible spectroscopy, fluorescence spectroscopy and methylene blue degradation tests. The results showed that zeolite matrix reduced agglomeration of nano-TiO2 and enhanced the absorption ability within the UV-Vis range, consequently increased the photocatalytic activity of the composites. Meanwhile, the influences of TiO2/zeolite proportion on their photocatalytic performances were explored, which indicated that 90 wt% TiO2/zeolite had optimal photocatalytic capability and stable properties.

The structural, constituent and surface properties of biomass-based carbon nanofibers were investigated by means of spectroscopic, microscopy, energy spectrometer and Brunauer-Emmet-Teller (BET) techniques. The results showed that the biomass-based carbon nanofibers had abundant pore structure and large specific surface area. The electrochemical performance of supercapacitor electrodes with the nanofibers was studied. This electrode showed a capacitance of 295 F/g at the current density of 1 A/g in 6 mol/L aqueous KOH electrolyte, and 98.5% capacity retention after 1000 charge/discharge cycles at the current density of 2 A/g. This indicate that the activate biomass-based carbon nanofibers have a good electrochemical stability. PMID- 29458634 TI - Comparison of Stabilizer Effects on the Size, Dispersion, and Catalytic Property of Pt, PtCu, and PtRu Nanoparticles. AB - Carbon-supported Pt, Pt-Cu, and Pt-Ru nanoparticles were prepared by an alcohol reduction method in the presence of carboxylates and phosphinate in order to investigate the role of these stabilizers in the nanoparticle formation process and the effect on catalytic properties in 2-propanol oxidation. For the Pt-Cu system, long chain carboxylate gave small dispersed particles even with high metal loading while phosphinate gave aggregated particles. For the Pt and Pt-Ru systems, fewer aggregates were observed and the particle size was independent of the chain length of carboxylate while much smaller and dispersed particles were obtained with phosphinate. Phosphinate mainly prevents metal crystal growth while carboxylates prevent both crystal growth and formation of aggregated particles. Although surface poisoning is severe on small dispersed particles in 2-propanol oxidation, dehydrogenation of 2-propanol at low potential is little affected. Phosphinate-protected catalysts were more tolerant to poisoning promoting 2 propanol electrooxidation at high potential range. The presence of Cu promoted 2 propanol electrooxidation at low potential range. These components made phosphinate-protected PtCu best perform in 2-propanol oxidation at 30 degrees C.

AB - NiCO2S4 with different morphology was controllably fabricated by a facile hydrothermal and solvothermal route. The as-obtained samples were analyzed and characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM). The results reveal that the sample (NCS 1) prepared by hydrothermal method manifest a mixture of nanorods and nanospheres. The sample (NCS-2) synthesized by solvothermal process takes on spherical nanoparticles (NPs). It is found that the morphology of the sample has much influence on the electrochemical property. When applied as anode for lithium ion batteries (LIBs), the NiCO2S4 NPs (NCS-2) possess the highest reversible discharge capacity of 1469.8 mAh g-1 compared with other two samples at the current density of 100 mA g-1 in the voltage window of 0.01-3 V. Additionally, it remains a specific capacity of 1163.7 mAh g-1 at a current density of 100 mAg-1 after 100 cycles. This excellent electrochemical performance arises from its unique mesoporous structure, which can reduce the transport lengths of both lithium ions and electrons. The mesoporous NiCO2S4 NPs show the great potential development of high-capacity anode materials for LIBs.

AB - In this paper, three-dimensional self-assembly graphene (3D-G) was prepared by the hydrothermal synthesis method, and 3D-G was designed as a suitable biological scaffold for cell growth and adhesion. The shape of 3D-G was tuned by adjusting the hydrothermal reaction time (6 h, 12 h, 18 h and 24 h). Then the scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), Raman spectroscopy and X-ray photoelectron spectroscopy (XPS) analyses were used to characterize the microstructure and component of 3D-G, which showed that the length, diameter, pore size and defects of 3D-G were all decreased as the reaction-time increased. In vitro cell culture experiment, the cytocompatibility of 3D-G prepared under different hydrothermal reaction time was assessed using mouse fibroblast cells (L929) via 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H tetrazolium bromide (MTT). Meanwhile, the cell adhesion, growth and proliferation were also observed by SEM. These results showed that the 3D-G with the reaction time of 24 h (3D-G/24 h) had the best cytocompatibility, which could be used as tissue scaffolds for cell growth.

AB - In this study, three different Ag micro/nano leaves were successfully synthesized through a galvanic displacement reaction by adjusting the concentration of Ag+. The catalytic activities of the prepared Ag micro/nano leaves toward ORR showed strong dependence on their morphology. An optimal concentration of Ag+ can result in a well-defined Ag micro/nano leaves with both crystallization and surface area, which showed the best activity towards ORR in alkaline media. In addition, the prepared Ag micro/nano leaves also showed high activity towards CO2 reduction, which required a potential of -0.8 V versus RHE to selectively convert CO2 to CO with the faradaic efficiency at about 20%. Compared with the Ag plate at the same overpotential, the FE has increased by 5-fold.

AB - In this paper, we developed an environmental friendly, cost effective, simple and green approach to reduce graphene oxide (GO) by a sulfate-reducing bacterium Desulfovibrio desulfuricans. The D. desulfuricans reduces exfoliated GO to reduced graphene oxide (rGO) at 25 degrees C in an aqueous solution without any toxic and environmentally harmful reducing agents. The rGO was characterized with X-ray Diffraction, Fourier Transform Infrared Spectroscopy, Scanning Electron Microscopy, Transmission Electron Microscope, X-ray Photoelectron Spectroscopy and Raman Spectroscopy. The analysis results showed that rGO had excellent properties and multi-layer graphene sheets structure. Furthermore, we demonstrated that D. desulfuricans, one of the primary bacteria responsible for the biocorrosion of various metals, might reduce GO to rGO on the surface of copper and prevented the corrosion of copper, which confirmed that electrophoretic deposition of GO on the surface of metals had great potential on the anti-biocorrosion applications.

AB - A real-time quartz crystal microbalance (QCM) cell activity monitoring system coupled with micro CCD cameras was developed to investigate the cultured cell activity, which could measure the viscoelastic characteristics of the cell with the QCM and observe the cell morphology changes with CCD camera simultaneously. Both the viscoelastic characteristics and the shape of the cultured cell are important factors to estimate the cell activity and the cell adhesion. The extracellular matrix (ECM) on the surface of the QCM is essential to culture the cell stably in the QCM monitoring system. To find the ECM optimization condition, the adhesive strength of cultured cells on the ECM modified glass surface was measured by using rotating water stream and CCD camera. After culturing HepG2 cells for 24 hours on the ECM modified glass plates, the glass plates were dipped in the PBS solution and rotated with 1,000, 1,300, and 1,500 rpm for 30 seconds. The adhesiveness of ECMs was investigated by calculating the remained cells after rotating. Four types of ECM, such as amino group, carboxyl group, collagen monomer, and collagen polymer, were used and tested. The current paper improves the sensing system of previous report so that measurements of four ECMs can be simultaneously conducted under the same conditions in order to enhance reliability. A collagen polymer exposed ECM was the most stable on an adhesiveness point of view, but not suitable for the QCM cell activity monitoring due to the decrease of the QCM sensitivity. The sensitivity of the QCM cell activity monitoring system using collagen monomer as ECM is about 2.6 times better than that using collagen polymer. A collagen monomer exposed ECM was more stable than amino group and carboxyl group exposed ECMs based on an adhesiveness point of view. Therefore, a collagen monomer exposed ECM was the most stable and suitable for the QCM cell activity monitoring system among the four ECMs. The changes of the resonance frequency and the resonance resistance of the ECM film with the cultured cells were investigated and compared the results of CCD camera images. From these results, we showed the QCM cell activity monitoring system coupled with the micro CCD camera could be applied to the evaluation of the cell activities.

AB - Vertically aligned undoped and Sb-doped ZnO (ZnSbO) nanorods were grown by the vapor-phase oxidation process on sapphire substrates at 700 degrees C using Fe as the catalyst. The effect of Sb doping on surface morphology, structural and optical properties of ZnO were studied. The grown undoped and Sb-doped ZnO nanorods have a hexagonal wurtzite structure with preferential c-axis orientation. The as-grown nanorods morphology has shown length of 2-5 MUm and a diameter of 100-250 nm. An elongated nanorods and high aspect ratio was observed in Sb-doped ZnO. The undoped ZnO nanorods showed a strong and sharp ultraviolet (UV) emission centered at ~381 nm, whereas Sb-doped ZnO nanorods exhibited two defect related emissions centered at ~530 nm (green) and ~630 nm (red) with a suppressed UV emission. The dominance of the red emission in the nanorods indicates that it exhibits a much higher defect caused by the Sb doping.

The morphologies and structures of the prepared photocatalysts were well characterized utilizing Transmission Electron Microscopy (TEM), X-ray Diffractometry (XRD), X-ray Photoelectron Spectroscopy (XPS) and UV Vis Diffuse Reflectance Spectrophotometer (DRS). The results indicated that the CeO2-QDs with 5 to 10 nm diameters were well dispersed and had a good contact with Cu2O. As observed in the photocatalytic experiments, Rhodamine B could be degraded more effectively under simulated sunlight using CeO2-QDs/Cu2O as the photocatalysts. Also, the obtained photocatalytic kinetics constant was higher than that in the experiments using CeO2 or Cu2O nano particles as photocatalysts. The enhanced photocatalytic activities might be attributed to the efficient separation of photo-generated charge carriers with the help of the p-n heterojunction and the morphology of quantum dots.

AB - Porous graphene sheets can be considered as an ultrathin membrane in reverse osmosis water desalination processes. In this paper, employing the molecular dynamics simulation method, the performance of multilayer porous graphene membranes with different pore sizes, layer separation, and layer number were investigated. We found that salt rejection and water flux through the membrane significantly depend on the graphene pore size and number of graphene layers, and controlling these parameters could improve the filtration process. It was shown that our 2-layer designed graphene membranes with the pore radius of 3.3 A and layer separation of 20 A, can reject more than 86% of ions. Also, no filtration process had occurred for graphene layer separation less than 5 A. The results of this study that are described by ion hydration radius and water velocity distributions can be used to improve the knowledge of water desalination at the molecular level, which leads to design more efficient multilayer graphene membranes for water purification.

AB - Poly(ethylene terephthalate) (PET) is a versatile engineering plastic which exhibits exceptional mechanical and thermal properties. Huge amounts of PET are consumed in various industries such as food packaging industry, textile industry, in the manufacturing of audio, video tapes and X-ray films and so on. But due to its substantial fraction by volume in water bodies and its high persistence to the atmospheric and biological agents, it could be considered as a hazard substance. Thereby chemical recycling of PET serves as a solution to solid waste problem as it transforms PET into its monomers via hydrolysis. Chemical recycling of post consumed waste PET bottles via alkaline hydrolysis is the main aim of this paper. Operating parameters such as reaction time and temperature were optimized for the conversion of PET into nanospindle-shaped terephthalic acid (TPA). Depolymerization of PET was carried out via alkaline hydrolysis by varying reaction time and temperature and maximum yield of 92% was obtained at 200 degrees C with reaction time of 25 minutes. The formed TPA nanospindles were further characterized in detail which exhibited high crystallinity, purity and fascinating thermal and surface properties.

AB - This paper focused on the influence of various oxidation parameters such as electrolyte composition, reaction time, calcination temperature and current change on the morphology and structure of TiO2 nanotube arrays. It was found that ammonium fluoride with a high viscosity reduced the diffusion rate of fluoride ions and significantly increased the length of TiO2 nanotubes, creating nanotubes with ordered arrays and uniform diameters. Meanwhile, the time of anodic oxidation determined the length of TiO2 nanotube arrays. Well-aligned nanotube arrays could be obtained after 0.5-2.5 h of oxidation. In addition, when the oxidation temperature was about 30 degrees C, the TiO2 nanotube arrays achieved the optimal uniformity and the maximum length-diameter aspect ratio. The morphology and quality of the TiO2 nanotubes fabricated were estimated through current as a function of reaction time. Consequently, formation mechanism of TiO2 nanotube arrays was investigated undergoing three major periods. The findings of this study can shed some light on the optimal conditions for preparing well aligned TiO2 nanotube arrays with high length-diameter aspect ratio.

AB - CdO nanoparticles were utilized in the fabrication of a composite membrane containing the ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate (BMIM+BF-4) for CO2 separation. The use of BMIM+BF-4containing CdO nanoparticles as a CO2 separator greatly improved separation performance. The ideal selectivity for CO2/N2 was 32.5 with a CO2 permeance of 57.1 GPU when CdO 4 liquid. The enhanced separation performance nanoparticles were incorporated into the BMIM+BF 4and the was attributed to increased CO2 solubility facilitated by both the free ions in BMIM+BF-4 oxide layer of the CdO nanoparticle. The CdO nanoparticles were identified with transmission electron microscopy and the physical and chemical properties of the membranes were investigated using scanning electron microscopy, Raman spectroscopy and TGA. Interestingly, we found a correlation between CO2 permeance and electronegativity differences between the metal and oxygen for CO2 separation membrane. The electronegativity differences between the metal and oxygen was ZnO (1.79) > CdO (1.75) > CuO (1.54) > AgO (1.51). The order of CO2 permeance was ZnO in BMIM+BF-4 (101 GPU) > CdO in BMIM+BF-4 (57.1 GPU) > CuO in BMIM+BF-4 (52.4 GPU) > AgO in BMIM+BF-4 (14.1 GPU).

The possible formation mechanism of the hollow GdF3 ellipsoids has been presented. The upconversion (UC) luminescence properties of the hollow GdF3: Yb3+/Ln3+ (Ln3+ = Er3+, Tm3+, Ho3+) ellipsoids were systematically investigated, which showed green (Er3+, 4S3/2, 2H11/2 -> 4I15/2), blue (Tm3+, 1G4 -> 3H6), and green (Ho3+, 5S2 -> 5I8) luminescence under 980 nm NIR excitation, respectively. Furthermore, the UC white light was successfully obtained in the GdF3: Yb3+/Er3+/Tm3+ sample through adjusting relative doping concentration of Yb3+, Er3+ and Tm3+ ions. These findings may reveal potential applications in the fields of laser, bioanalysis, optoelectronic and nanoscale devices due to multicolor emissions in the visible region.

AB - Flattening of a carbon nanotube with a switching of the flattening direction results in the formation of a nanotetrahedron/nanoribbon structure. In this study, behavior of individual carbon nanotetra-hedron/nanoribbon structures under a tensile load is observed by means of in-situ scanning electron microscopy using micro-manipulators. Positions of breakage caused by a tensile load are not necessarily at a nanotetrahedron/nanoribbon junction. The results indicate that the nanotetrahedron/nanoribbon junctions are not mechanical weak points under a tensile load, and the nanotetra-hedron/nanoribbon structures are as strong as simple multi-walled carbon nanotubes. In addition, the nanostructures maintain their shape and do not transformed to a tubular form. PMID- 29458649 TI - Synthesis of PbS and Ag2S Nanorods via Polyol Process. AB - PbS and Ag2S nanorods have been synthesized using a polyol process in the presence of poly(vinylpyrrolidone) (PVP). First, the production of Pb or Ag was realized via the thermal decomposition of a lead/silver salt. Then the Pb or Ag precursor was directly combined with S power under heating, leading to the formation of the final products. The samples were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and energy dispersive X-ray spectroscopy (EDS). PbS cubes and cubes with a hole in the center were prepared under different reaction conditions. Possible formation mechanisms of different PbS or Ag2S morphologies have briefly been discussed.

AB - Nano-SiO2 is an inexpensive material for enzyme immobilization and has been frequently utilized for this purpose. In addition to its low cost, Nano-SiO2 has several advantages when used as a supporting material, including its lack of toxicity and chemical reactivity, allowing easy fixation of enzymes. In this article, Porcine Pancreatic lipase was non-covalently immobilized on Nano-SiO2. The properties of immobilized enzyme were then defined. The optimum pH and temperature for the immobilized PPL for hydrolysis of olive oil were determined as 7.6 and 40-50 degrees C, respectively. The immobilized enzyme possessed high stability in batch operation; with 73.5% of the initial activity still remaining after 8 times of repeated operation of the immobilized lipase. The immobilized enzyme was more stable than free enzyme and t1/2 was 25 d, while free lipase activity was lost 50% in 2 days. The apparent Km for the immobilized enzyme was significantly smaller than that of the free one.

AB - In this research, hexagonal and cubic mesoporous silica with ordered parallel pore channels was synthesized using odd chain-length N-undecanoyl-L-alanine sodium salt and even chain-length N-lauroyl-L-alanine sodium salt as template respectively. Aminopropylsiloxane was used as the co-structure-directing agents (CSDA). The ordered mesostructure was characterized by infrared spectroscopy, small X-ray diffraction patterns (XRD), scanning electron microscope (SEM), trasmission electron microscope (TEM), and nitrogen sorption analysis. The results indicated that mesoporous silica which was prepared by asymmetric odd chain-length surfactants presented a looser strucuture with large volume than mesoporous silica prepared by the even chain-length surfactant. It led to the transformation from 2D hexagonal (p6mm) phase to cubic (Ia-3d) mesophase. PMID- 29458652 TI - Morphology Control of Eu-Doped Amorphous Gehlenite Phosphors Prepared by Spray Pyrolysis. AB - Eu-doped amorphous gehlenite phosphors with various morphologies were synthesized using spray pyrolysis. Along with un-treated precursor, two commonly used pore forming agents, polyethylene glycol and hydrogen peroxide, were applied to achieve porous and hollow particle structures. The phase compositions, surface morphologies, inner structures and photoluminescence properties of the resulting phosphors were examined by X-ray diffraction, scanning electron microscopy, transmission electron microscopy and fluorescence spectrometry. The results showed that the morphologies of the particles were well-controlled, and a correlation between morphology and photoluminescence properties was established. PMID- 29458653 TI - Does the Abiotic Formation of Oligopeptides on TiO2 Nanoparticles Require Special Catalytic Sites? Apparently Not. AB - The oligomerization of non-activated amino acids catalyzed by nanostrucrured mineral oxide surfaces holds promises as a sustainable route for the industrial production of polypeptides. To analyze the influence of the surface type on the catalytic process, we performed, via a mild Chemical Vapor Deposition approach, the oligomerization of Glycine on two samples of TiO2 nanoparticles characterized by different relative amounts of defective surface terminations. Based on infrared spectroscopy and mass spectrometry data, we show herein that the formation of peptide bonds on titania nanoparticles does not require highly energetic surface terminations, but can occur also on the most abundant and thermodynamically most stable {101} facets of nanosized anatase. PMID- 29458655 TI - DL-endopeptidases function as both cell wall hydrolases and poly-gamma-glutamic acid hydrolases. AB - Biopolymers on the cell surface are very important for protecting microorganisms from environmental stresses, as well as storing nutrients and minerals. Synthesis of biopolymers is well studied, while studies on the modification and degradation processes of biopolymers are limited. One of these biopolymers, poly-gamma glutamic acid (gamma-PGA), is produced by Bacillus species. Bacillus subtilis PgdS, possessing three NlpC/P60 domains, hydrolyses gamma-PGA. Here, we have demonstrated that several dl-endopeptidases with an NlpC/P60 domain (LytE, LytF, CwlS, CwlO, and CwlT) in B. subtilis digest not only an amide bond of d-gamma glutamyl-diaminopimelic acid in peptidoglycans but also linkages of gamma-PGA produced by B. subtilis. The hydrolase activity of dl-endopeptidases towards gamma-PGA was inhibited by IseA, which also inhibits their hydrolase activity towards peptidoglycans, while the hydrolysis of PgdS towards gamma-PGA was not inhibited. PgdS hydrolysed only the d-/l-Glu-d-Glu linkages of d-Glu-rich gamma PGA (d-Glu:l-Glu=7 : 3) and l-Glu-rich gamma-PGA (d-Glu:l-Glu=1 : 9), indicating that PgdS can hydrolyse only restricted substrates. On the other hand, the dl endopeptidases in B. subtilis cleaved d-/l-Glu-d-/l-Glu linkages of d-Glu-rich gamma-PGA (d-Glu:l-Glu=7 : 3), indicating that these enzymes show different substrate specificities. Thus, the dl-endopeptidases digest gamma-PGA more flexibly than PgdS, even though they are annotated as "dl-endopeptidase, digesting the d-gamma-glutamyl-diaminopimelic acid linkage (d-l amino acid bond)". PMID- 29458654 TI - Identification and characterization of viral defective RNA genomes in influenza B virus. AB - Influenza B virus (FLUBV) is an important pathogen that infects humans and causes seasonal influenza epidemics. To date, little is known about defective genomes of FLUBV and their roles in viral replication. In this study, by using a next generation sequencing approach, we analyzed total mRNAs extracted from A549 cells infected with B/Brisbane/60/2008 virus (Victoria lineage), and identified four defective FLUBV genomes with two (PB1?A and PB1?B) from the polymerase basic subunit 1 (PB1) segment and the other two (M?A and M?B) from the matrix (M) protein-encoding segment. These defective genomes contained significant deletions in the central regions with each having the potential for encoding a novel polypeptide. Significantly, each of the discovered defective RNAs can potently inhibit the replication of B/Yamanashi/166/98 (Yamagata lineage). Furthermore, PB1?A was able to interfere modestly with influenza A virus (FLUAV) replication. In summary, our study provides important initial insights into FLUBV defective interfering genomes, which can be further explored to achieve better understanding of the replication, pathogenesis and evolution of FLUBV. PMID- 29458656 TI - Stress responses, outer membrane permeability control and antimicrobial resistance in Enterobacteriaceae. AB - Bacteria have evolved several strategies to survive a myriad of harmful conditions in the environment and in hosts. In Gram-negative bacteria, responses to nutrient limitation, oxidative or nitrosative stress, envelope stress, exposure to antimicrobials and other growth-limiting stresses have been linked to the development of antimicrobial resistance. This results from the activation of protective changes to cell physiology (decreased outer membrane permeability), resistance transporters (drug efflux pumps), resistant lifestyles (biofilms, persistence) and/or resistance mutations (target mutations, production of antibiotic modification/degradation enzymes). In targeting and interfering with essential physiological mechanisms, antimicrobials themselves are considered as stresses to which protective responses have also evolved. In this review, we focus on envelope stress responses that affect the expression of outer membrane porins and their impact on antimicrobial resistance. We also discuss evidences that indicate the role of antimicrobials as signaling molecules in activating envelope stress responses. PMID- 29458657 TI - Digestion of peptidoglycan near the cross-link is necessary for the growth of Bacillus subtilis. AB - Bacterial cells are covered with peptidoglycan (PG) layer(s), serving as the cellular exoskeleton. The PG sacculus changes its shape during cell growth, and thus both the synthesis and disassembly of PG are important for cell proliferation. In Bacillus subtilis, four dl-endopeptidases (DLEPases; LytE, LytF, CwlO and CwlS) are involved in the maintenance of cell morphology. The lytE cwlO double mutant exhibits synthetic lethality and defective cell elongation, while the lytE lytF cwlS triple mutant exhibits defective cell separation, albeit with septum formation. LytE is involved in both cell separation and elongation. We propose that DLEPases have varied roles in cell separation and elongation. To determine these roles, the catalytic domain of LytE was substituted with another catalytic domain that digests the other bonds in PG. By using the chimeric enzymes, we assessed the suppression of the synthetic lethality by the cell elongation defect and the disruption of chain morphology by the cell separation defect. All the constructed chimeric enzymes suppressed the cell separation defect, restoring the chain morphology. Digestion at any position of PG broke the linkage between two daughter cells, releasing them from each other. However, only d,d-endopeptidases suppressed the lack of DLEPase in the lytE cwlO double mutant. This indicated that the release of tension on the expanding PG sacculus is not the sole essential function of DLEPases. Considering that the structure of the digested PG is important for cell elongation, the digested product might be reused in the growth process in some way. PMID- 29458658 TI - Halomonas saliphila sp. nov., a moderately halophilic bacterium isolated from a saline soil. AB - A novel, Gram-stain-negative, aerobic, rod-shaped, motile and moderately halophilic bacterium, designated strain LCB169T, was isolated from a saline soil sample from Gansu Province, PR China. The cells of LCB169T grew at 10-52 degrees C (optimum 30 degrees C), at pH 6.0-10.0 (optimum pH 8.0) and in the presence of 0-17 % (w/v) NaCl (optimum 10-15 %). Phylogenetic analysis based on 16S rRNA gene sequences and concatenated 16S rRNA, gyrB and rpoD genes sequences revealed that LCB169T represented a member of the genus Halomonas in the class Gammaproteobacteria. The most closely related species were Halomonas daqingensis DQD2-30T (98.0 % 16S rRNA gene sequence similarity), Halomonas kenyensis AIR-2T (97.8 %) and Halomonas desiderata FB2T (97.5 %). DNA-DNA relatedness values between LCB169T and H. daqingensis CGMCC 1.6443T, H. desiderata DSM 9502T and H. kenyensis DSM 17331T were 33, 35 and 38 %, respectively. The polar lipids were identified as diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine and three unidentified phospholipids. The major fatty acids were C18 : 1omega7c, C16 : 0, C16 : 1omega7c and C12 : 0 3-OH. The genomic DNA G+C content was 66.1 mol% and the predominant respiratory quinone was Q-9. On the basis of the results of phenotypic, phylogenetic and chemotaxonomic analyses and DNA-DNA hybridization relatedness values, LCB169T is considered to represent a novel species of the genus Halomonas, for which the name Halomonas saliphila sp. nov. is proposed. The type strain is LCB169T (=CGMCC 1.15818T=KCTC 52618T). PMID- 29458660 TI - Identification of antigenic proteins from Mycobacterium avium subspecies paratuberculosis cell envelope by comparative proteomic analysis. AB - Johne's disease (JD) is a contagious, chronic granulomatous enteritis of ruminants caused by Mycobacterium avium subsp. paratuberculosis (MAP). The aim of this study was to identify antigenic proteins from the MAP cell envelope (i.e. cell wall and cytoplasmic membranes) by comparing MAP, M. avium subsp. hominissuis (MAH) and M. smegmatis (MS) cell envelope protein profiles using a proteomic approach. Composite two-dimensional (2D) difference gel electrophoresis images revealed 13 spots present only in the image of the MAP cell envelope proteins. Using serum from MAP-infected cattle, immunoblot analysis of 2D gels revealed that proteins in the 13 spots were antigenic. These proteins were identified by liquid chromatography tandem mass spectrometry as products of the following genes: sdhA, fadE25_2, mkl, citA, gapdh, fadE3_2, moxR1, mmp, purC, mdh, atpG, fbpB and desA2 as well as two proteins without gene names identified as transcriptional regulator (MAP0035) protein and hypothetical protein (MAP1233). Protein functions ranged from energy generation, cell wall biosynthesis, protein maturation, bacterial replication and invasion of epithelial cells, functions considered essential to MAP virulence and intracellular survival. Five MAP cell envelope proteins, i.e. SdhA, FadE25_2, FadE3_2, MAP0035 and DesA2 were recombinantly expressed, three of which, i.e. SdhA, FadE25_2 and DesA2, were of sufficient purity and yield to generate polyclonal antibodies. Immunoblot analysis revealed antibodies reacted specifically to the respective MAP cell envelope proteins with minimal cross reactivity with MAH and MS cell envelope proteins. Identification and characterization of MAP-specific proteins and antibodies to those proteins may be useful in developing new diagnostic tests for JD diagnosis. PMID- 29458659 TI - Relationship of environmental disturbances and the infectious potential of fungi. AB - Fungi are critical organisms for the environment and offer many benefits to modern society through their application in the pharmaceutical, beverage and food industries. In contrast, fungal pathogens are emerging threats to humans, animals, plants and insects with potential to cause devastating mortality, morbidity and economic loss. Outbreaks associated with anthropogenic alterations of the environment, including climate change-related events such as natural disasters, are responsible for human, animal and plant disease. Similarly, fungi and their metabolites also have a negative impact in agriculture, posing a serious threat to our food supplies. Here, we describe the existing knowledge and importance of understanding the relationship of fungi and the environment in the context of human, animal and plant disease. Our goal is to encourage communication between scientists and the general public to create informed awareness about the impact of fungi in their daily lives and their environment. PMID- 29458661 TI - Chicken astrovirus as an aetiological agent of runting-stunting syndrome in broiler chickens. AB - Despite descriptions of runting-stunting syndrome (RSS) in broiler chickens dating back over 40 years, the aetiology has not yet been described. A novel chicken astrovirus (CkAstV) was isolated in an LMH liver cell line from the intestines of chickens affected with RSS. Clinical RSS is characterized by retarded growth and cystic crypt lesions in the small intestine. In 1-day-old broiler chickens infected with the CkAstV isolate, virus was only detected in the intestinal epithelial cells during the first few days after infection. Notably, the preferred host cells are the crypt epithelial cells following initial replication in the villous epithelial cells, thus implying viral preference for immature intestinal cells. Nevertheless, the CkAstV isolate did not induce remarkable pathological changes, despite the presence of the virus in situ. Serial chicken-to-chicken passages of the virus induced increased virulence, as displayed by decreased weight gain and the presence of cystic lesions in the small intestine reproducing clinical RSS in chickens. The analysis of the full length genome sequences from the isolated CkAstV and the CkAstV from the bird-to bird passages showed >99 % similarity. The data obtained in this study suggest that the CkAstV isolate is capable of inducing RSS following serial bird-to-bird passages in broilers and is as an aetiological agent of the disease. PMID- 29458662 TI - Spirosoma horti sp. nov., isolated from apple orchard soil. AB - A Gram-negative, motile by gliding, rod-shaped, aerobic bacterium, designated S7 3-19T, was isolated from apple orchard soil in Gyeongsangnam-do Province, Republic of Korea, and characterized taxonomically by using a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequencing showed that strain S7-3-19T belonged to the family Cytophagaceae and was most closely related to Spirosoma linguale DSM 74T (96.38 %), Spirosoma fluviale MSd3T (96.38 %), Spirosoma pulveris JSH5-14T (96.35 %) and Spirosoma radiotolerans DG5AT (96.24 %). Chemotaxonomic characteristics supported the classification of strain S7-3 19T within the genus Spirosoma. Summed feature 3 (C16 : 1omega7c/C16 : 1omega6c; 46.7 %) and C16 : 1omega5c (23.8 %) were the major fatty acids. Phosphatidylethanolamine, an unidentified aminophospholipid, an unidentified phospholipid and two unidentified lipids were the major polar lipids. Menaquinone with seven isoprene units was the predominant respiratory quinone. The G+C content of the genomic DNA of strain S7-3-19T was 48.6 mol%. On the basis of its phenotypic properties, genotypic distinctiveness and chemotaxonomic features, strain S7-3-19T represents a novel species of the genus Spirosoma, for which the name Spirosomahorti sp. nov. is proposed. The type strain is S7-3-19T (=KCTC 52728T=JCM 32131T). PMID- 29458663 TI - Cytochromes in anaerobic growth of Acidithiobacillus ferrooxidans. AB - The mineral sulfide-oxidising Acidithiobacillus ferrooxidans has been extensively studied over many years but some fundamental aspects of its metabolism remain uncertain, particularly with regard to its anaerobic oxidation of sulfur. This label-free, liquid chromatography-electron spray ionisation-mass spectrometry based proteomic analysis estimated relative protein abundance during aerobic and anaerobic growth of At. ferrooxidans. One of its two bc1 complexes, that encoded by the petII operon, was strongly implicated in anaerobic ferric iron-coupled sulfur oxidation, probably in conjunction with two cytochromes. These two cytochromes are homologs of the Cyc2 and Cyc1 proteins that are involved in ferrous iron oxidation. The previously undetected cytochromes apparently associated with anaerobic growth in At. ferrooxidans appear to be absent in many other ferrous iron-oxidising acidophiles that can also reduce ferric iron, which suggests a diversity in the ferric-iron-coupled sulfur oxidation pathways. For aerobic growth of At. ferrooxidans, this analysis was consistent with the generally accepted mechanism for its oxidation of ferrous iron. Unexpectedly, proteins encoded by the petI operon were not abundant and generally not detected in the proteomic analyses of cells grown aerobically on sulfur, although there was some expression of genes of the petI and petII operons in these cells. PMID- 29458664 TI - Loving the poison: the methylcitrate cycle and bacterial pathogenesis. AB - Propionate is an abundant catabolite in nature and represents a rich potential source of carbon for the organisms that can utilize it. However, propionate and propionate-derived catabolites are also toxic to cells, so propionate catabolism can alternatively be viewed as a detoxification mechanism. In this review, we summarize recent progress made in understanding how prokaryotes catabolize propionic acid, how these pathways are regulated and how they might be exploited to develop novel antibacterial interventions. PMID- 29458665 TI - Death and gastrointestinal bleeding complicate encephalomyelitis in mice with delayed appearance of CNS IgM after intranasal alphavirus infection. AB - Central nervous system (CNS) infection of C57BL/6 mice with the TE strain of Sindbis virus (SINV) provides a valuable animal model for studying the pathogenesis of alphavirus encephalomyelitis. While SINV TE inoculated intracranially causes little mortality, 20-30 % of mice inoculated intranasally (IN) died 8 to 11 days after infection, the period during which immune cells typically infiltrate the brain and clear infectious virus. To examine the mechanism behind the mortality, mice infected IN with SINV TE were monitored for evidence of neurological disease, and those with signs of severe disease (moribund) were sacrificed and tissues collected. Mice showing the usual mild signs of encephalomyelitis were concurrently sacrificed to serve as time-matched controls (sick). Sixty-eight per cent of the moribund mice, but none of the sick mice, showed upper gastrointestinal bleeding due to gastric ulceration. Clinical disease and gastrointestinal pathology could not be attributed to direct viral infection of tissues outside of the CNS, and brain pathology and inflammation were comparable in sick and moribund mice. However, more SINV antigen was present in the brains of moribund mice, and clearance of infectious virus from the CNS was delayed compared to sick mice. Lower levels of SINV-specific IgM and fewer B220+ B cells were present in the brains of moribund mice compared to sick mice, despite similar levels of antiviral IgM and IgG in serum. These findings highlight the importance of the local antibody response in determining the outcome of viral encephalomyelitis and offer a model system for understanding individual variation in this response. PMID- 29458666 TI - Saccharopolyspora deserti sp. nov., a novel halotolerant actinobacterium isolated from a desert. AB - Strain SYSU D8010T was isolated from a desert sand sample collected in Saudi Arabia. The taxonomic position of the isolate was investigated by the polyphasic taxonomic approach. The isolate was found to be Gram-positive and aerobic. The strain was able to grow at 14-40 degrees C, pH 5.0-9.0 and in the presence of up to 22 % (w/v) NaCl. Strain SYSU D8010T contained meso-diaminopimelic acid as cell wall diamino acid, and arabinose, fucose, galactose, glucose and rhamnose as the whole-cell sugars. The primary polar lipids were diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, phosphatidylinositol and phosphatidylinositolmannosides. Menaquinone MK-9(H4) was detected as the respiratory quinone; and anteiso-C17 : 0, iso-C16 : 0, iso-C15 : 0 and iso-C17 : 0 as the predominant fatty acids. Pairwise comparison of the 16S rRNA gene sequences indicated that strain SYSU D8010T had a sequence similarity of 97.8 % to Saccharopolyspora halophila YIM 90500T. The genomic DNA G+C content of strain SYSU D8010T was determined to be 69.9 mol%. Based on the analyses of the phenotypic, genotypic and phylogenetic characteristics, strain SYSU D8010T was determined to represent a novel species of the genus Saccharopolyspora, for which the name Saccharopolyspora deserti sp. nov. is proposed. The type strain of the species is SYSU D8010T (=KCTC 39989T=CPCC 204620T). PMID- 29458667 TI - vacA s1m1 genotype and cagA EPIYA-ABC pattern are predominant among Helicobacter pylori strains isolated from Mexican patients with chronic gastritis. AB - PURPOSE: Virulent genotypes of Helicobacter pylori vacA s1m1/cagA+/babA2+ have been associated with severe gastric diseases. VacA, CagA and BabA are polymorphic proteins, and their association with the disease is allele-dependent. The aims of this work were: (i) to determine the prevalence of H. pylori by type of chronic gastritis; (ii) to describe the frequency of cagA, babA2 and vacA genotypes in strains from patients with different types of chronic gastritis; (iii) to characterize the variable region of cagA alleles. METHODOLOGY: A total of 164 patients with chronic gastritis were studied. Altogether, 50 H. pylori strains were isolated, and the status of cagA, babA2 and vacA genotypes was examined by PCR. cagA EPIYA segment identification was performed using PCR and sequencing of cagA fragments of six randomly selected strains.Results/Key findings. The overall prevalence of H. pylori was 30.5 %. Eighty percent of the isolated strains were vacA s1m1, and the cagA and babA2 genes were detected in 74 and 32 % of the strains, respectively. The most frequent genotypes were vacA s1m1/cagA+/babA2- and vacA s1m1/cagA+/babA2+, with 40 % (20/50) and 28 % (14/50), respectively. In cagA+, the most frequent EPIYA motif was -ABC (78.4 %), and EPIYA-ABCC and -ABCCC motifs were found in 10.8 % of the strains. A modified EPIYT-B motif was found in 66.6 % of the sequenced strains. CONCLUSION: H. pylori strains carrying vacA s1m1, cagA+ and babA2- genotypes were the most prevalent in patients with chronic gastritis from the south of Mexico. In the cagA+ strains, the EPIYA-ABC motif was the most common. PMID- 29458668 TI - Shift of microbial composition of peri-implantitis-associated oral biofilm as revealed by 16S rRNA gene cloning. AB - PURPOSE: Micro-organisms are important triggers of peri-implant inflammation and analysing their diversity is necessary for peri-implantitis treatment. This study aimed to analyse and compare the microbiota associated with individuals with peri implantitis, as well as clinically healthy implant sites. METHODOLOGY: Subgingival biofilm samples were taken from 10 individuals with peri-implantitis and from at least 1 clinically healthy implant. DNA was extracted and bacterial 16S rRNA genes were amplified using universal primers. After cloning the PCR products, amplified inserts of positive clones were digested using restriction endonucleases, and the chosen clones were sequenced. The 16S rDNA-sequences were compared to those from the public sequence databases GenBank, EMBL and DDBJ to determine the corresponding taxa. RESULTS: Differing distributions of taxa belonging to the phyla Firmicutes, Bacteroidetes, Fusobacteria, Actinobacteria, Proteobacteria, Synergistetes, Spirochaetae and TM 7 were detected in both the healthy implant (HI) and the peri-implantitis (PI) groups. A significantly higher relative abundance of phylum Bacteroidetes, as well as of the species Fusobacterium nucleatum, were found in the PI group (P<0.05). The putative periodontal red complex (Porphyromonas gingivalis, Tannerella forsythia) was also detected at significantly higher levels in the PI group (P<0.05), whereas the yellow group, as well as the species Veillonella dispar, tended to be associated with the HI group. CONCLUSION: A shift in the healthy subgingival microbiota was shown in peri-implantitis-associated biofilm. Anaerobic Gram-negative periopathogens, including P. gingivalis and T. forsythia, seem to play an important role in peri-implantitis development and should be considered in treatment and prevention strategies. PMID- 29458669 TI - Chloromonas arctica sp. nov., a psychrotolerant alga from snow in the High Arctic (Chlamydomonadales, Chlorophyta). AB - With the advent of molecular phylogenetic methods, it has become possible to assess the bioversity of snow algae more accurately. In this study, we focused on a morphological, ultrastructural and taxonomic description of a new Chloromonas like alga isolated from snow in the High Arctic (Svalbard). Light and transmission electron microscopy revealed broad ellipsoidal or ellipsoidal cylindrical, occasionally spherical cells with a chloroplast without a pyrenoid, an inconspicuous eyespot and a papilla. The size difference and the aforementioned morphological traits clearly distinguished the alga from its closest counterparts within the genus Chloromonas. Moreover, we were able to cultivate the alga at both 5 and 20 degrees C, revealing the psychrotolerant nature of the strain. Phylogenetic analyses of the plastid rbcL and nuclear 18S rRNA gene showed that the alga is nested within a clade containing a number of psychrotolerant strains within the Chloromonadinia phylogroup (Chlorophyceae). In the rbcL phylogeny, the alga formed an independent lineage, sister to the freshwater species Chloromonas paraserbinowii. Comparisons of secondary structure models of a highly variable ITS2 rDNA marker showed support for a distinct species identity for the new strain. The ITS2 secondary structure of the new isolate differed from the closest matches 'Chlamydomonas' gerloffii and Choloromonas reticulata by three and five compensatory base changes, respectively. Considering the morphological and molecular differences from its closest relatives, a new psychrotolerant species from the Arctic, Choromonas arctica sp. nov., is proposed. PMID- 29458670 TI - Chicken anaemia virus evades host immune responses in transformed lymphocytes. AB - Chicken anaemia virus (CAV) is a lymphotropic virus that causes anaemia and immunosuppression in chickens. Previously, we proposed that CAV evades host antiviral responses in vivo by disrupting T-cell signalling, but the precise cellular targets and modes of action remain elusive. In this study, we examined gene expression in Marek's disease virus-transformed chicken T-cell line MSB-1 after infection with CAV using both a custom 5K immune-focused microarray and quantitative real-time PCR at 24, 48 and 72 h post-infection. The data demonstrate an intricate equilibrium between CAV and the host gene expression, displaying subtle but significant modulation of transcripts involved in the T cell, inflammation and NF-kappaB signalling cascades. CAV efficiently blocked the induction of type-I interferons and interferon-stimulated genes at 72 h. The cell expression pattern implies that CAV subverts host antiviral responses and that the transformed environment of MSB-1 cells offers an opportunistic advantage for virus growth. PMID- 29458671 TI - Roseisolibacter agri gen. nov., sp. nov., a novel slow-growing member of the under-represented phylum Gemmatimonadetes. AB - A novel slow-growing bacterium, designated strain AW1220T, was isolated from agricultural floodplain soil sampled at Mashare (Kavango region, Namibia) by using a high-throughput cultivation approach. Strain AW1220T was characterized as a Gram-negative, non-motile, rod-shaped bacterium. Occasionally, some cells attained an unusual length of up to 35 um. The strain showed positive responses for catalase and cytochrome-c oxidase and divided by binary fission and/or budding. The strain had an aerobic chemoorganoheterotrophic metabolism and was also able to grow under micro-oxic conditions. Colonies were small and pink pigmented. Strain AW1220T was found to be a mesophilic, neutrophilic and non halophilic bacterium. Cells accumulated polyphosphate intracellularly and mainly utilized complex protein substrates for growth. 16S rRNA gene sequence comparisons revealed that strain AW1220T belonged to the class Gemmatimonadetes (=group 1). Its closest relatives were found to be Gemmatimonas aurantiaca T-27T (90.9 % gene sequence similarity), Gemmatimonas phototrophica AP64T (90.8 %) and Longimicrobiumterrae CB-286315T (84.2 %). The genomic G+C content was 73.3 mol%. The major fatty acids were iso-C15 : 0, C16 : 1omega7c and/or iso-C15 : 0 2-OH, iso-C17 : 1omega9c, iso-C15 : 0 3-OH and C16 : 0. The predominant respiratory quinone was MK-9, albeit minor amounts of MK-8 and MK-10 are also present. The polar lipids comprised major amounts of phosphatidylethanolamine, phosphatidylcholine, diphosphatidylglycerol and one unidentified phosphoglycolipid. On the basis of its polyphasic characterization, strain AW1220T represents a novel genus and species of the class Gemmatimonadetes for which the name Roseisolibacter agri gen. nov., sp. nov. is proposed, with the type strain AW1220T (=DSM 104292T=LMG 29977T).

AB - Triacylglycerol (TAG) and starch produced by micro-algae are potential sources of biofuel. Our previous studies showed that the unicellular green alga, Chlamydomonas debaryana NIES-2212, which is a rare species of Chlamydomonas that possesses phosphatidylcholine (PC), is a seed organism for the development of biofuel producers. This alga accumulates large amounts of TAG and starch under completely photo-autotrophic conditions during stationary phase without nutrient deprivation. The present study was performed to optimize the growth conditions of this alga with regard to light intensity and CO2 concentration to improve the efficiency of TAG and starch production. The growth rate of C. debaryana was greater at higher light intensity, although there was no significant difference in the final cell density of the culture. The highest contents of TAG and starch, approximately 200 fmol cell-1 and 600 pg cell-1, respectively, were achieved with a light intensity of 200 umol m-2 s-1 bubbled with air containing 5.0 % CO2. These results suggest that optimization of light intensity and CO2 concentration can enhance the productivity of TAG and starch by C. debaryana NIES-2212. PMID- 29458673 TI - Denture-associated biofilm infection in three-dimensional oral mucosal tissue models. AB - PURPOSE: In vitro analyses of virulence, pathogenicity and associated host cell responses are important components in the study of biofilm infections. The Candida-related infection, denture-associated oral candidosis, affects up to 60 % of denture wearers and manifests as inflammation of palatal tissues contacting the denture-fitting surface. Commercially available three-dimensional tissue models can be used to study infection, but their use is limited for many academic research institutions, primarily because of the substantial purchase costs. The aim of this study was to develop and evaluate the use of in vitro tissue models to assess infections by biofilms on acrylic surfaces through tissue damage and Candida albicans virulence gene expression. METHODOLOGY: In vitro models were compared against commercially available tissue equivalents (keratinocyte-only, SkinEthic; full-thickness, MatTek Corporation). An in vitro keratinocyte-only tissue was produced using a cancer-derived cell line, TR146, and a full-thickness model incorporating primary fibroblasts and immortalised normal oral keratinocytes was also generated. The in vitro full-thickness tissues incorporated keratinocytes and fibroblasts, and have potential for future further development and analysis. RESULTS: Following polymicrobial infection with biofilms on acrylic surfaces, both in-house developed models were shown to provide equivalent results to the SkinEthic and MatTek models in terms of tissue damage: a significant (P<0.05) increase in LDH activity for mixed species biofilms compared to uninfected control, and no significant difference (P>0.05) in the expression of most C. albicans virulence genes when comparing tissue models of the same type. CONCLUSION: Our results confirm the feasibility and suitability of using these alternative in vitro tissue models for such analyses. PMID- 29458674 TI - Restoration of sensitivity of a diverse set of drug-resistant Staphylococcus clinical strains by bactericidal protein P128. AB - PURPOSE: P128, a phage-derived lysin, exerts antibacterial activity on staphylococci by cleaving the pentaglycine-bridge of peptidoglycan. We sought to determine whether the presence of P128 could re-sensitize drug-resistant bacteria to antibiotics by virtue of its cell wall degrading property. METHODOLOGY: P128 was tested in combination with standard-of-care (SoC) drugs by chequerboard assays on planktonic cells and biofilms of strains individually resistant to these drugs. The bactericidal effect of P128 and drug combinations on planktonic cells and biofilms was measured by c.f.u. reduction assays. A mouse model of MRSA bacteraemia was used to test the efficacy of P128 and oxacillin in combination. RESULTS: A combination of sub-MIC P128 (0.025-0.20 ug ml-1) and 0.5 ug ml-1 of oxacillin resulted in inhibition of bacterial growth in four MRSA strains. Similar results were seen with all the other drugs tested, wherein sub-MIC of P128 re-sensitized S. aureus and CoNS strains to SoC drugs. The chequerboard assays on strains of S. aureus and CoNS showed that combinations of P128 and antibiotics consistently inhibited bacterial growth on biofilms. Data from scanning electron microscopy and c.f.u. reduction assays on drug-resistant S. aureus and CoNS demonstrated that sub-MICs of P128 and SoC antibiotics could kill biofilm-embedded bacteria. In vivo, a combination of sub-therapeutic doses of P128 and oxacillin could help protect animals from fatal bacteraemia. CONCLUSION: The ability of P128 to re-sensitize bacteria to SoC drugs suggests that combinations of P128 and SoC antibiotics can potentially be developed to treat infections caused by drug-resistant strains of staphylococci. PMID- 29458675 TI - The contribution of SP100 to cottontail rabbit papillomavirus transcription and replication. AB - SP100 proteins are components of nuclear domain 10 structures and have been implicated as inhibitors of human papillomavirus (HPV) replication. In this study, we have addressed the role of SP100 in tumour formation by the cottontail rabbit (Sylvilagus floridanus) papillomavirus (CRPV or SfPV1) in a rabbit model. Tissue culture studies using rabbit keratinocyte lines indicated that rabbit SP100 is an interferon-beta-inducible gene similar to its human counterpart. Stable knockdown of SP100 by shRNA in a cell line harbouring CRPV genomes resulted in a decrease of viral early transcripts. In contrast, infection of domestic rabbits with recombinant CRPV genomes expressing short hairpin (sh)RNAs directed against SP100 did not reveal changes in tumour formation rate, tumour size or early viral transcript levels. However, late viral transcript levels and viral genome copies were consistently lower in CRPV/shSP100-induced tumours than in the control, but these differences did not reach statistical significance. In summary, this study suggests that rabbit SP100 is not an inhibitor but an activator of CRPV replication and transcription. PMID- 29458676 TI - Emergence of resistance to ciprofloxacin in Neisseria meningitidis in Brazil. AB - To prevent secondary invasive meningococcal disease (IMD) cases and outbreaks, antimicrobial prophylaxis of high-risk contacts is indicated. This study reports two ciprofloxacin-resistant Neisseria meningitidis strains in Brazil. The 3523 N. meningitidis isolates collected throughout Brazil from 2009 to 2016 were evaluated for antimicrobial resistance. Meningococcal isolates showing minimal inhibitory concentrations, MICs>=0.125ug ml-1 to ciprofloxacin, were analysed to determine the presence of mutations in the quinolone resistance-determining regions (QRDRs) of gyrA and parC genes. Two ciprofloxacin-resistant N. meningitidis isolates were found, both presenting a single mutation in the quinolone resistance-determining region of the gyrA gene. These results confirmed that ciprofloxacin is still a first-line drug for chemoprophylaxis. However, we highlight the importance of continued surveillance to monitor the trends of N. meningitidis susceptibility profiles to the antimicrobials recommended for chemoprophylaxis and IMD treatment. PMID- 29458677 TI - Methylomusa anaerophila gen. nov., sp. nov., an anaerobic methanol-utilizing bacterium isolated from a microbial fuel cell. AB - Abacterial strain, designated MMFC1T, was isolated from a methanol-fed microbial fuel cell that had been inoculated with sludge obtained from a wastewater treatmentfacility in a chemical plant. The strain grows by fermenting methanol to produce acetate under anaerobic conditions, while homoacetogenic growth is not observed. MMFC1T also grows on pyruvate and lactate but not on sugars and other organic acids. Cells are curved rods and motile, have peritrichous flagella, and form endospores. The genome sequence of strain MMFC1T supports the physiological data. Phylogenetic analysis based on the 16S rRNA gene sequence shows that strain MMFC1T is affiliated with the family Sporomusaceae, while the closest relative is Sporomusa ovata with nucleotide-sequencesimilarity of 93.5 %. Major fatty acids are iso-C13 : 0 3-OH, C16 : 1omega9 and iso-C17 : 0. On the basis of its physiological, genomic and phylogenetic features, a novel genus and species are proposed to accommodate strain MMFC1T, with the name Methylomusa anaerophila gen. nov., sp. nov. The type strain of Methylomusa anaerophila is MMFC1T (=JCM 31821T = KCTC 15592T). PMID- 29458678 TI - Accumulation of ornithine lipids in Vibrio cholerae under phosphate deprivation is dependent on VC0489 (OlsF) and PhoBR system. AB - Ornithine lipids (OLs) are phosphorus-free lipids found in many bacteria grown under phosphate deprivation, a condition that activates the PhoBR system and leads to phosphate uptake and metabolism. Two OL synthesis pathways have already been described. One depends on OlsB and OlsA acyltransferases to add, respectively, the first and second acyl chains to an ornithine molecule. The other pathway is carried out by OlsF, a bifunctional enzyme responsible for both acylation steps. Although Vibrio cholerae lacks olsBA genes, an olsF homologue (vc0489) was identified in its genome. In this work we demonstrated that V. cholerae produces OLs and expresses vc0489 in response to phosphate depletion, in a PhoBR-dependent manner. In Escherichia coli, under similar condition, vc0489 expression leads to OL accumulation. These results indicate a strong connection between OL synthesis and VC0489 from V. cholerae and, for the first time, a direct regulation of an olsF homologue by the PhoBR system. PMID- 29458679 TI - Transitional and temporal changes in the mucosal and submucosal intestinal microbiota in advanced Crohn's disease of the terminal ileum. AB - PURPOSE: Crohn's disease is a chronic debilitating intestinal syndrome of unknown aetiology that is thought to result in part from an imbalance (dysbiosis) of the intestinal microbial populations, known as the microbiota. In this study we sought to compare the microbiota at the mucosal and submucosal levels at the resection margin in Crohn's disease to those in other intestinal dysbiotic disease controls to determine the level of bacterial translocation. METHODOLOGY: 16S microbiota sequencing was performed on DNA extracted from mucosal and submucosal samples from resected intestinal tissues from Crohn's disease and controls. RESULTS: Grossly normal appearing tissue at the resection margin showed early signs, suggesting bacterial translocation, with two bacterial families having penetrated the mucosal surfaces. In contrast, 4 and 13 bacterial families were present within submucosal tissues at the disease centre and disease margin, respectively. Although there was no significant difference in biodiversity, there was increased bacterial richness in the Crohn's disease group as compared to non IBD controls. CONCLUSION: The presence and/or absence of certain bacteria suggested disease-specific ecological or micro-environmental pressures driving or excluding certain organisms in Crohn's disease. The data suggest that several of the dysbiotic conditions previously reported for Crohn's disease are not unique but common to general dysbiosis. The examination of multiple intestinal sites in advanced disease may provide a spectrum of disease from early onset at the resection margin to active disease at the disease margin and late-stage fibrostenotic disease at the centre of the lesion, and a unique etiopathogenic view of Crohn's disease. PMID- 29458680 TI - Colony analysis and deep learning uncover 5-hydroxyindole as an inhibitor of gliding motility and iridescence in Cellulophaga lytica. AB - Iridescence is an original type of colouration that is relatively widespread in nature but has been either incompletely described or entirely neglected in prokaryotes. Recently, we reported a brilliant 'pointillistic' iridescence in agar-grown colony biofilms of Cellulophaga lytica and some other marine Flavobacteria that exhibit gliding motility. Bacterial iridescence is created by a unique self-organization of sub-communities of cells, but the mechanisms underlying such living photonic crystals are unknown. In this study, we used Petri dish assays to screen a large panel of potential activators or inhibitors of C. lytica's iridescence. Derivatives potentially interfering with quorum sensing and other communication or biofilm formation processes were tested, as well as metabolic poisons or algal exoproducts. We identified an indole derivative, 5-hydroxyindole (5HI, 250 uM) which inhibited both gliding and iridescence at the colonial level. 5HI did not affect growth or cell respiration. At the microscopic level, phase-contrast imaging confirmed that 5HI inhibits the gliding motility of cells. Moreover, the lack of iridescence correlated with a perturbation of self-organization of the cell sub-communities in both the WT and a gliding-negative mutant. This effect was proved using recent advances in machine learning (deep neuronal networks). In addition to its effect on colony biofilms, 5HI was found to stimulate biofilm formation in microplates. Our data are compatible with possible roles of 5HI or marine analogues in the eco-biology of iridescent bacteria. PMID- 29458681 TI - Broad neutralization response in a subset of HIV-1 subtype C-infected viraemic non-progressors from southern India. AB - Broadly neutralizing antibodies (bnAbs) have been considered to be potent therapeutic tools and potential vaccine candidates to enable protection against various clades of human immunodeficiency virus (HIV). The generation of bnAbs has been associated with enhanced exposure to antigen, high viral load and low CD4+ T cell counts, among other factors. However, only limited data are available on the generation of bnAbs in viraemic non-progressors that demonstrate moderate to high viraemia. Further, since HIV-1 subtype C viruses account for more than 50 % of global HIV infections, the identification of bnAbs with novel specificities is crucial to enable the development of potent tools to aid in HIV therapy and prevention. In the present study, we analysed and compared the neutralization potential of responses in 70 plasma samples isolated from ART-naive HIV-1 subtype C-infected individuals with various disease progression profiles against a panel of 30 pseudoviruses. Among the seven samples that exhibited a neutralization breadth of >=70 %, four were identified as 'elite neutralizers', and three of these were from viraemic non-progressors while the fourth was from a typical progressor. Analysis of the neutralization specificities revealed that none of the four elite neutralizers were reactive to epitopes in the membrane proximal external region (MPER), CD4-binding site and V1V2 or V3 glycan. However, two of the four elite neutralizers exhibited enhanced sensitivity towards viruses lacking N332 glycan, indicating high neutralization potency. Overall, our findings indicate that the identification of potent neutralization responses with distinct epitope specificities is possible from the as yet unexplored Indian population, which has a high prevalence of HIV-1 subtype C infection. PMID- 29458682 TI - Frankia saprophytica sp. nov., an atypical, non-infective (Nod-) and non-nitrogen fixing (Fix-) actinobacterium isolated from Coriaria nepalensis root nodules. AB - Strain CN3T, a Coriaria nepalensis isolate, appears to form hyphae and sporangia typical of members fo the genus Frankia. However, it failed to form vesicles, to reduce acetylene and to induce nodules on its original host plant. A polyphasic approach was used here to determine the taxonomic status of strain CN3T. The 16S rRNA gene sequence of strain CN3T showed the highest sequence identity with Frankia asymbiotica type strain M16386T (99.4 %). Digital DNA-DNA hybridization between strains CN3T and M16386T was 25.7 %, which is clearly below the accepted cut-off point of 70 %. The G+C content of DNA was 71.8 mol%. Whole-cell hydrolysates of strain CN3T were rich in meso-diaminopimelic acid. Cell-wall sugars were composed of galactose, glucose, mannose, rhamnose and traces of ribose. The polar lipid profile contained phosphatidylinositol, phosphatidylglycerol, diphosphatidylglycerol, phosphoglycolipids, phospholipid, six uncharacterized glycolipids and two uncharacterized lipids. The predominant menaquinone (>25 %) was MK-9(H6). Major fatty acids (>15 %) of strain CN3T consisted of iso-C16 : 0, C17 : 1omega8c and C15 : 0. Based on 16S rRNA gene phylogeny, genome sequence analysis and phenotypic results, strain CN3T (=DSM 105290T=CECT 9314T) is proposed to represent the type strain of a novel species, Frankia saprophytica sp. nov. PMID- 29458683 TI - Engineering Escherichia coli to grow constitutively on D-xylose using the carbon efficient Weimberg pathway. AB - Bio-production of fuels and chemicals from lignocellulosic C5 sugars usually requires the use of the pentose phosphate pathway (PPP) to produce pyruvate. Unfortunately, the oxidation of pyruvate to acetyl-coenzyme A results in the loss of 33 % of the carbon as CO2, to the detriment of sustainability and process economics. To improve atom efficiency, we engineered Escherichia coli to utilize d-xylose constitutively using the Weimberg pathway, to allow direct production of 2-oxoglutarate without CO2 loss. After confirming enzyme expression in vitro, the pathway expression was optimized in vivo using a combinatorial approach, by screening a range of constitutive promoters whilst systematically varying the gene order. A PPP-deficient (DeltaxylAB), 2-oxoglutarate auxotroph (Deltaicd) was used as the host strain, so that growth on d-xylose depended on the expression of the Weimberg pathway, and variants expressing Caulobacter crescentus xylXAB could be selected on minimal agar plates. The strains were isolated and high-throughput measurement of the growth rates on d-xylose was used to identify the fastest growing variant. This strain contained the pL promoter, with C. crescentus xylA at the first position in the synthetic operon, and grew at 42 % of the rate on d xylose compared to wild-type E. coli using the PPP. Remarkably, the biomass yield was improved by 53.5 % compared with the wild-type upon restoration of icd activity. Therefore, the strain grows efficiently and constitutively on d-xylose, and offers great potential for use as a new host strain to engineer carbon efficient production of fuels and chemicals via the Weimberg pathway. PMID- 29458684 TI - Global survey of Klebsiella pneumoniae major porins from ertapenem non susceptible isolates lacking carbapenemases. AB - PURPOSE: To understand the diversity of porin disruption in Klebsiella pneumoniae, the major outer membrane protein (OMP) porins, OmpK35 and OmpK36, were examined in a set of isolates that did not harbour traditional carbapenem hydrolysing enzymes, but nevertheless tested non-susceptible to ertapenem. METHODS: A world-wide collection of Klebsiella pneumoniae isolates that were part of the Study for Monitoring Antimicrobial Resistance Trends (SMART) surveillance project over the years 2008-2014 were characterised with regard to their beta lactamase gene carriage and potential permeability defects. Four hundred and eighty-seven isolates that did not carry carbapenemase genes, but were non susceptible to ertapenem, were investigated by sequence analysis of the genes encoding OmpK35 and OmpK36. Isolates without obvious genetic lesions in either major porin gene were further examined by outer membrane protein SDS-PAGE. RESULTS: The majority of isolates, 83.0 % (404/487), exhibited clear genetic disruption in either or both of the ompK35 and ompK36 genes. Among the proportion of the collection with the highest ertapenem MIC value (>4 mg l-1), 60.5 % (115/190) showed mutation in both porin genes. Isolates without obvious genetic mutations were examined by SDS-PAGE, and 90.4 % (75/83) were found to lack or show altered expression of at least one of the major OMPs when compared to an ertapenem sensitive control strain. CONCLUSION: This study illustrates that porin deficiency in Klebsiella pneumoniae is a widespread phenomenon, and in combination with ESBLs and/or AmpC enzymes, likely accounts for the elevated ertapenem MICs observed in this study. PMID- 29458685 TI - Optimizing host cell physiology and stress avoidance for the production of recombinant human tumour necrosis factor alpha in Escherichia coli. AB - As high-level recombinant protein production (RPP) exerts a massive stress on the production host, an extensive literature on RPP optimization focuses on separating the growth phase from RPP production once sufficient biomass has been obtained. The aim of the current investigation was to optimize the benefits of the relatively neglected alternative strategy to achieve high-level RPP during growth by minimizing stress on the host. High yields of the biopharmaceutical recombinant human tumour necrosis factor alpha (rhTNFalpha) were obtained by fed batch fermentation relevant to industrial production based upon parameters that most severely affected RPP in preliminary laboratory scale batch cultures. Decreasing the inducer concentration and growth temperature, but increasing the production period, were far more effective for increasing RPP yields than changing the growth phase at which production was induced. High yields of up to 5 g l-1 of rhTNFalpha were obtained with minimal plasmid loss, even in synthetic media that lack animal-derived components and are therefore fully compliant with regulatory requirements. Most of the product was soluble and biologically active. In summary, stress minimization was shown to be an effective way to optimize the production of rhTNFalpha. Data generated in shake-flask experiments allowed the design of intensified bioreactor cultures in which RPP and growth could be balanced, leading to higher yield of both rhTNFalpha and biomass than with previous fermentations. An additional benefit of this approach is avoidance of lysis during harvesting and downstream processing. PMID- 29458687 TI - MALDI-TOF mass spectrometry and high-consequence bacteria: safety and stability of biothreat bacterial sample testing in clinical diagnostic laboratories. AB - We considered the application of MALDI-TOF mass spectrometry for BSL-3 bacterial diagnostics, with a focus on the biosafety of live-culture direct-colony testing and the stability of stored extracts. Biosafety level 2 (BSL-2) bacterial species were used as surrogates for BSL-3 high-consequence pathogens in all live-culture MALDI-TOF experiments. Viable BSL-2 bacteria were isolated from MALDI-TOF mass spectrometry target plates after 'direct-colony' and 'on-plate' extraction testing, suggesting that the matrix chemicals alone cannot be considered sufficient to inactivate bacterial culture and spores in all samples. Sampling of the instrument interior after direct-colony analysis did not recover viable organisms, suggesting that any potential risks to the laboratory technician are associated with preparation of the MALDI-TOF target plate before or after testing. Secondly, a long-term stability study (3 years) of stored MALDI-TOF extracts showed that match scores can decrease below the threshold for reliable species identification (<1.7), which has implications for proficiency test panel item storage and distribution. PMID- 29458686 TI - DNA extraction from primary liquid blood cultures for bloodstream infection diagnosis using whole genome sequencing. AB - PURPOSE: Speed of bloodstream infection diagnosis is vital to reduce morbidity and mortality. Whole genome sequencing (WGS) performed directly from liquid blood culture could provide single-assay species and antibiotic susceptibility prediction; however, high inhibitor and human cell/DNA concentrations limit pathogen recovery. We develop a method for the preparation of bacterial DNA for WGS-based diagnostics direct from liquid blood culture. METHODOLOGY: We evaluate three commercial DNA extraction kits: BiOstic Bacteraemia, Amplex Hyplex and MolYsis Plus. Differential centrifugation, filtration, selective lysis and solid phase reversible immobilization bead clean-up are tested to improve human cells/DNA and inhibitor removal. Using WGS (Illumina/MinION), we assess human DNA removal, pathogen recovery, and predict species and antibiotic susceptibility inpositive blood cultures of 44 Gram-negative and 54 Staphylococcus species.Results/Key findings. BiOstic kit extractions yield the greatest mean DNA concentration, 94-301 ng ul-1, versus 0-2.5 ng ul-1 using Amplex and MolYsis kits. However, we note higher levels of inhibition (260/280 ratio 0.9-2.1) and human DNA (0.0-4.4*106 copies) in BiOstic extracts. Differential centrifugation (2000 g, 1 min) prior to BiOstic extraction reduces human DNA by 63-89 % with selective lysis minimizing by a further 62 %. Post-extraction bead clean-up lowers inhibition. Overall, 67 % of sequenced samples (Illumina MiSeq) contain <10 % human DNA, with >93 % concordance between WGS-based species and susceptibility predictions and clinical diagnosis. If >60 % of sequencing reads are human (7/98 samples) susceptibility prediction becomes compromised. Novel MinION-based WGS (n=9) currently gives rapid species identification but not susceptibility prediction. CONCLUSION: Our method for DNA preparation allows WGS based diagnosis direct from blood culture bottles, providing species and antibiotic susceptibility prediction in a single assay. PMID- 29458688 TI - Implementation of a rapid influenza A/B and RSV direct molecular assay improves emergency department oseltamivir use in paediatric patients. AB - PURPOSE: Influenza A virus (FluA), influenza B virus (FluB) and respiratory syncytial virus (RSV) illnesses increase hospitalizations during seasonal epidemics. METHODOLOGY: To determine the utility of the Simplexa FluA/B & RSV Direct Assay (Direct Flu/RSV) and its impact on oseltamivir use, we offered this assay to emergency department (ED) patients with influenza-like illness. RESULTS: Utilization of the Direct Flu/RSV provided a turnaround time (TAT) of 2 hours. Compared to the flu season prior to implementation of the Direct Flu/RSV, clinicians were more likely to prescribe 5 days of oseltamivir therapy for Direct Flu/RSV-positive patients in comparison to those with a negative test. CONCLUSIONS: Use of Direct Flu/RSV provides results rapidly, which leads to more appropriate use of oseltamivir. The ease of use of this assay and quick TAT allows for prompt decision-making, which is essential for patient care and effective disease control during the influenza season. PMID- 29458689 TI - The YscE/YscG chaperone and YscF N-terminal sequences target YscF to the Yersinia pestis type III secretion apparatus. AB - The needle structures of type III secretion (T3S) systems are formed by the secretion and polymerization of a needle subunit protein, YscF in Yersinia pestis. A subset of T3S systems employ unique heterodimeric chaperones, YscE and YscG in Y. pestis, to prevent the polymerization of needle subunits within the bacterial cell. We demonstrate that the YscE/YscG chaperone is also required for stable YscF expression and for secretion of YscF. Overexpression of a functional maltose-binding protein (MBP)-YscG hybrid protein stabilized cytoplasmic YscF but YscF was not secreted in the absence of YscE. Furthermore, a YscE mutant protein was identified that functioned with YscG to stabilize cytosolic YscF; however, YscF was not secreted. These findings confirm a role for the YscE/YscG chaperone in YscF secretion and suggest that YscE may have a specific role in this process. Recent studies have shown that YscF deleted of its N-terminal 15 residues is still secreted and functional, suggesting that YscF may not require an N-terminal secretion signal. However, we demonstrate that YscF contains an N-terminal secretion signal and that a functional N-terminal signal is required for YscF secretion. PMID- 29458690 TI - Anti-inflammatory effect of two Lactobacillus strains during infection with Gardnerella vaginalis and Candida albicans in a HeLa cell culture model. AB - Lactobacilli are the dominant bacteria of the vaginal tract of healthy women and they play a major role in the maintenance of mucosal homeostasis, preventing genital infections, such as bacterial vaginosis (BV) and vulvovaginal candidiasis (VVC). It is now known that one mechanism of this protection is the influence that lactobacilli can exert on host immune responses. In this context, we evaluated two Lactobacillus strains (L. plantarum 59 and L. fermentum 137) for their immunomodulatory properties in response to Gardnerella vaginalis (BV) or Candida albicans (VVC) infections in a HeLa cell infection model. G. vaginalis and C. albicans triggered the secretion of pro-inflammatory cytokines (TNF-alpha, IL-1beta, IL-6 and IL-8) and the activation of NF-kappaB in HeLa cells, in contrast to L. plantarum 59 and L. fermentum 137. Treatments with the Lactobacillus strains or their cell-free supernatants before (pre-treatment) or after (post-treatment) the challenge with the pathogens resulted in decreased secretion of pro-inflammatory cytokines and decreased activation of NF-kappaB. The treatments with Lactobacillus strains not only decreased the secretion of IL 8, but also its expression, as confirmed by gene reporter luciferase assay, suggesting transcription-level control by lactobacilli. In conclusion, L. plantarum 59 and L. fermentum 137 were confirmed to have an anti-inflammatory effect against G. vaginalis and C. albicans and they were able to influence signalling in NF-kappaB pathway, making them interesting candidates as probiotics for the prevention or treatment of BV and VVC. PMID- 29458691 TI - Nightmare Themes: An Online Study of Most Recent Nightmares and Childhood Nightmares. AB - STUDY OBJECTIVES: Even though the common diagnostic criteria (ICSD-3, DSM-5) acknowledge that nightmares do not only contain anxiety/fear (definition of the ICD-10) but also other emotions such as grief, disgust, and anger, the definition of a nightmare still focuses on threats to survival, security, or physical integrity. However, empirical studies on nightmare content in larger samples are scarce. METHODS: The current study elicited 1,216 of the most recent nightmares including childhood nightmares of a population-based sample. RESULTS: The findings show that nightmares encompass a diversity of different topics, being chased, physical aggression, including death/injury of close persons. Infrequent themes like being the aggressor and suicide are of special interest as they might be related to waking-life psychopathology. CONCLUSIONS: The variety of nightmare topics clearly indicate that current definitions of nightmare content are too narrow. Future studies should look into nightmare content of persons in whom nightmare disorder has been diagnosed. PMID- 29458692 TI - Effect of Sleep-Disordered Breathing on Albuminuria in 273 Patients With Type 2 Diabetes. AB - STUDY OBJECTIVES: Sleep-disordered breathing (SDB) can induce hyperglycemia, hypertension, and oxidative stress, conditions that are known to cause kidney damage. Therefore, SDB may exacerbate albuminuria, which is an established marker of early-stage kidney damage in patients with type 2 diabetes mellitus (T2DM). The association between SDB and albuminuria in patients with T2DM was investigated in this study. METHODS: This cross-sectional study included 273 patients with T2DM who underwent portable sleep testing and measurement of urine albumin to creatinine ratio (UACR). The association between the severity of SDB and albuminuria was investigated. Patients were divided into three groups according to the respiratory event index (REI): the no or mild group (REI < 15 events/h), moderate (REI 15 to < 30 events/h), and severe (REI >= 30 events/h). Albuminuria was defined as UACR >= 3.4 mg/mmol creatinine. Logistic regression analysis for albuminuria included the categorical REI as the independent variable. RESULTS: The median (interquartile range) REI of all patients (age 57.9 +/- 11.9 years, mean +/- standard deviation, male sex 81.7%, body mass index 26.7 [24.2-29.5] kg/m2, estimated glomerular filtration rate 82 [65-97] mL/min/1.73 m2) was 13.0 (7.0-24.2) events/h. The REI, as a categorical variable, was significantly associated with albuminuria after adjustment for other risk factors for albuminuria; REI 15 to < 30 events/h: odds ratio (OR) 3.35, 95% confidence interval (95% CI), 1.68-6.67, P < .001; REI >= 30: OR 8.52, 95% CI, 3.52-20.63, P < .001). In addition, the natural logarithm-transformed REI of all patients also correlated significantly with albuminuria. CONCLUSIONS: The severity of SDB is associated with albuminuria in patients with T2DM. PMID- 29458693 TI - The Impact of Continuous Positive Airway Pressure on Circulating IGF-1 in Patients With Obstructive Sleep Apnea. AB - STUDY OBJECTIVES: Obstructive sleep apnea (OSA) is a disease with metabolic and cardiovascular consequences and is associated with decreased serum concentrations of insulin-like growth factor-1 (IGF-1). The aim of this study was to investigate whether continuous positive airway pressure (CPAP) will increase serum IGF-1 concentration in patients with OSA. METHODS: Patients with moderate to severe OSA were recruited from a sleep clinic and serum IGF-1 was measured before initiation of CPAP and at follow-up after 4.8 +/- 2.5 months. Patients adherent to CPAP treatment (usage >= 4 h/night) were compared with those considered to be nonadherent (usage < 4 h/night). RESULTS: Complete data were obtained from 69 patients (86% male, age 56 +/- 12 years, respiratory event index 43 +/- 21 events/h, Epworth Sleepiness Scale score 12 +/- 5). In those adherent to CPAP (n = 42), there was an increase in serum IGF-1 concentration with 21.1 (95% confidence interval [CI]: 13.1 to 29.2) MUg/L compared to 4.7 (95% CI: -4.1 to 13.5) MUg/L in the nonadherent group (n = 27) (P = .0083). In a linear multivariate model adjusting for sex, age, body mass index, respiratory event index, and mean oxygen saturation during the night recording, the change in serum IGF-1 concentration was significantly associated with adherence to CPAP treatment (adjusted beta coefficient: 21.8, 95% CI: 10.2 to 33.4) and inversely associated with change in body mass index (adjusted beta coefficient: -7.1, 95% CI: -11.3 to -3.0) and change in hemoglobin A1c (adjusted beta coefficient: -1.8, 95% CI: -33 to -0.3). CONCLUSIONS: CPAP usage >= 4 h/night is associated with increased serum IGF-1 concentration in male patients with OSA. PMID- 29458694 TI - Persistent High Residual AHI After CPAP Use. AB - ABSTRACT: Treatment-emergent central sleep apnea has recently been noted after various treatment modalities for obstructive sleep apnea. It often remits spontaneously or can be treated with continuous positive airway pressure. However, we encountered a pediatric patient with obstructive sleep apnea who presented with severe complications, including growth failure, attention-deficit hyperactivity disorder, poor school performance, daytime sleepiness, and urinary difficulty that required permanent cystostomy. His obstructive sleep apnea resolved after adenotonsillectomy. However, treatment-emergent central sleep apnea developed after adenotonsillectomy and was further aggravated after continuous positive airway pressure and bilevel positive airway pressure without a backup respiratory rate use. After bilevel positive airway pressure with a backup respiratory rate treatment for 3 months initially, all his symptoms improved, except growth failure. Later, after adaptive servoventilation was used for 10 months, the patient's growth began to improve. PMID- 29458695 TI - Comorbid Insomnia With Obstructive Sleep Apnea: Clinical Characteristics and Risk Factors. AB - STUDY OBJECTIVES: Obstructive sleep apnea (OSA) and chronic insomnia are two common sleep disorders and both are considered independent risk factors for heart disease. The aim of this study was to investigate the prevalence of comorbid insomnia with OSA and to compare its clinical characteristics with those of OSA without insomnia. METHODS: Patients who visited two tertiary university hospital sleep centers were screened. Those with a diagnosis of OSA using polysomnography were divided into two groups based on their scores on the Korean version of the Insomnia Severity Index (ISI-K): OSA with insomnia (OSA+I) (ISI-K score >= 15) and OSA without insomnia (OSA-I) (ISI-K score < 15). Subjective symptoms were evaluated using sleep questionnaires including ISI-K. Demographic and clinical characteristics of OSA+I and OSA-I were compared. RESULTS: Out of 476 patients with OSA, 139 (29.2%) had significant insomnia. Patients in the OSA+I group had a higher percentage of females (35.3% versus 19.6%, P < .001) and have higher rates of heart disease (19.4% versus 8.6%, P < .001). OSA+I group showed lower quality of life, lower quality of sleep, higher sleep propensity, and higher depression as measured by the Korean versions of the Short-Form 36-Item Health Survey, Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, and Beck Depression Inventory, respectively. There were no significant differences in adherence to continuous positive airway pressure between the groups. CONCLUSIONS: There is a high prevalence of comorbid insomnia with OSA (29.2%), consistent with previous findings in Western studies. Comorbid insomnia with OSA may constitute a cumulative risk factor for cardiovascular disease. These findings warrant further investigation into the mechanisms involved in its pathogenesis and devising more efficient treatments. PMID- 29458696 TI - Characterization of Respiratory Events in Obstructive Sleep Apnea Using Suprasternal Pressure Monitoring. AB - STUDY OBJECTIVES: In obstructive sleep apnea (OSA) esophageal pressure (Pes) is the gold standard for measurement of respiratory effort, and respiratory inductance plethysmography (RIP) is considered an accepted measurement technique. However, the use of RIP could lead to limited accuracy in certain cases and therefore suprasternal pressure (SSP) monitoring might improve the reliability of OSA diagnosis. We aimed to use SSP for the visual characterization of respiratory events in adults and compared results to those obtained by RIP from polysomnography (PSG). METHODS: In patients with OSA, a 1-night SSP recording using the PneaVoX sensor (Cidelec, Sainte-Gemmes-sur-Loire, France) was done. In parallel, PSG was performed according to American Academy of Sleep Medicine criteria. A subgroup of patients agreed to have Pes measurement in addition. Characterizations of apneas as obstructive, central, and mixed as well as hypopneas as central and obstructive were done by visual evaluation of SSP, RIP, and Pes in random order by two independent scores (S1 and S2). The sensitivity and specificity of characterization by SSP compared to RIP and to Pes were calculated. RESULTS: Synchronous recordings of SSP and PSG were analyzed from n = 34 patients with OSA (AHI 34.1 +/- 24.2 events/h); 9 of them had synchronized Pes monitoring as well. Interscorer agreement for apnea characterization as obstructive, central, and mixed based on SSP, RIP, and Pes were found, with R2 values from 0.91-0.99. The sensitivity of SSP in apnea characterization with reference to RIP (S1/S2) was 91.5%/92.3% for obstructive, 82.7%/76.2% for central, and 87.4%/79.9% for mixed. The sensitivity of SSP in apnea characterization with reference to Pes was (S1/S2) 93.1%/92.1% for obstructive, 80.8%/81.6% for central, and 91.7%/90.8% for mixed. Hypopnea was only classified for the nine patients with Pes. CONCLUSIONS: This study demonstrated a good agreement in the detection of respiratory effort with the SSP signal using the PneaVoX sensor compared to the RIP belts signals as well as to the Pes signal. These findings were consistently found by two independent scorers. In summary, results suggest that SSP is a reliable signal for the classification of respiratory events and could be used as an additional tool for OSA characterization in clinical practice. PMID- 29458697 TI - Long-Term Impact of Sleep-Disordered Breathing on Quality of Life in Children With Obesity. AB - STUDY OBJECTIVES: (1) To determine baseline quality of life (QOL) among children with obesity and newly diagnosed moderate-severe sleep-disordered breathing (SDB) and to compare it to the reported QOL of children with obesity or SDB alone and healthy children. (2) To evaluate QOL change after 1 year. METHODS: A prospective multicenter cohort study was conducted in children (8-16 years) with obesity, prescribed positive airway pressure (PAP) therapy for moderate-severe SDB. Outcomes included parent-proxy and self-report total and subscale scores on the PedsQL questionnaire (baseline and 1-year). RESULTS: Total PedsQL scores were indicative of impaired QOL in 69% of cases based on parent-report and in 62% on self-report. Parents reported significantly lower QOL in our cohort than that reported in other studies for children with obesity or SDB alone or healthy children, on total PedsQL score and on social and psychosocial subscales. PedsQL total scores for participants were significantly higher (mean difference 7.3 +/- 15.3, P = .03) than those reported by parents. Parents reported significant improvements in total PedsQL (mean change 7.29 +/- 13.73, P = .04) and social functioning (mean change 17.65 +/- 24.69, P = .04) scores after 1 year. No significant differences were found by children's self-report or by PAP adherence. CONCLUSIONS: QOL of children with obesity and SDB is lower than in children with obesity or SDB alone or healthy children. One year later, children reported no significant changes in QOL; parents reported significant improvements in total PedsQL and social functioning scores. PAP adherence did not significantly affect QOL change in this population. COMMENTARY: A commentary on this article appears in this issue on page 307.

AB - ABSTRACT: This is a rare case of non-24-hour sleep-wake rhythm disorder in a sighted male with normal functioning. The patient, a 23-year-old doctorate graduate student, presented with difficulty falling asleep and excessive daytime sleepiness. He reported variable sleep and wake times. Overnight baseline polysomnography was unremarkable and his Multiple Sleep Latency Test was significant for short mean sleep latency. Sleep diary and actigraphy were obtained, which demonstrated a pattern of delaying of sleep and wake times each day. He had excellent symptom response to nightly melatonin. PMID- 29458699 TI - Continuous Positive Airway Pressure Therapy in Gestational Diabetes With Obstructive Sleep Apnea: A Randomized Controlled Trial. AB - STUDY OBJECTIVES: Obstructive sleep apnea (OSA) is associated with gestational diabetes mellitus (GDM). This study assessed the effects of continuous positive airway pressure (CPAP) in obese pregnant females with GDM and OSA. METHODS: A randomized controlled trial was conducted (April 2014 - June 2016). Obese females at 24 to 34 weeks gestation and with diet-controlled GDM were screened for OSA. Those with OSA were randomly assigned to receive 2 weeks nightly CPAP or be part of a waitlist control group. After 2 weeks, all patients were offered CPAP. The primary outcome was glucose metabolism, obtained from an oral meal tolerance test (MTT) at baseline and 2 weeks. Pregnancy outcomes were collected. RESULTS: Eighteen patients were randomized to CPAP and 18 to control groups. There were no significant changes between groups in fasting glucose, glucose response to MTT, and insulin sensitivity or secretion after 2 weeks. Those adherent to CPAP had significantly improved insulin secretion (P = .016) compared to the control group. When a counterfactual instrumental variable approach was applied to deal with nonadherence, the CPAP group had significantly improved insulin secretion (P = .002) and insulin sensitivity (P = .015). Lower rates of preterm delivery (P = .002), unplanned cesarean section (P = .005), and neonatal intensive care unit admissions (P < .001) were observed among those who used CPAP longer than 2 weeks. CONCLUSIONS: Two weeks of CPAP in females with GDM and OSA did not result in improved glucose levels, but insulin secretion improved in those adherent to CPAP. Continued CPAP use was possibly associated with improved pregnancy outcomes.

PMID- 29458700 TI - Sleep Health and Predicted Cardiometabolic Risk Scores in Employed Adults From Two Industries. AB - STUDY OBJECTIVES: Sleep disorders and sleep deficiency can increase the risk for cardiovascular disease. Less is known about whether multiple positive attributes of sleep health known as the SATED (satisfaction, alertness, timing, efficiency, and duration) model, can decrease future cardiovascular disease risks. We examined whether and how a variety of indicators of sleep health predicted 10 year estimated cardiometabolic risk scores (CRS) among employed adults. METHODS: Workers in two industries-extended care (n = 1,275) and information technology (IT; n = 577)-reported on habitual sleep apnea symptoms and sleep sufficiency, and provided 1 week of actigraphy data including nighttime sleep duration, wake after sleep onset (WASO), sleep timing, and daytime napping. Workers also provided biomarkers to calculate future cardiometabolic risk. RESULTS: More sleep apnea symptoms predicted higher CRS in both industries. More sleep sufficiency, less WASO, and less daytime napping (having no naps, fewer naps, and shorter nap duration) were also linked to lower CRS, but only in the extended care workers. There was no effect of sleep duration in both industries. In the IT employee sample, shorter sleep duration (<= 6 hours versus 6-8 hours) and more naps strengthened the link between sleep apnea and CRS. CONCLUSIONS: Sleep health, measured by both subjective and objective methods, was associated with lower cardiometabolic disease risks among extended care workers (lower to middle wage workers). Sleep apnea was an important predictor of CRS; for the IT workers, the link between sleep apnea and CRS was exacerbated when they had poorer sleep health behaviors. PMID- 29458701 TI - Impact of Arterial Stiffness on WatchPAT Variables in Patients With Obstructive Sleep Apnea. AB - STUDY OBJECTIVES: The WatchPAT is a wrist-worn portable device that creates integration data regarding peripheral arterial tone (PAT), oxyhemoglobin saturation, heart rate, and actigraphy to diagnose or screen for obstructive sleep apnea (OSA). Previous studies have demonstrated the efficacy and validity of respiratory variables measured by the WatchPAT compared to those using polysomnography (PSG). However, the effects of arterial stiffness or atherosclerosis on WatchPAT parameters remain to be elucidated. METHODS: Sixty one consecutive patients with suspected OSA who underwent home-based testing with the WatchPAT 200, standard in-laboratory overnight polysomnography (PSG), and pulse wave velocity (PWV) as an index of arterial stiffness were studied. All PSG recordings were scored manually using the American Academy of Sleep Medicine criteria, whereas WatchPAT data were analyzed by an automatic algorithm. We evaluated how arterial stiffness affected respiratory event index data in WatchPAT (WP-AHI), because WP-AHI could be partly influenced by PAT, comparing WP AHI and the apneahypopnea index measured by PSG (PSG-AHI) in consideration of PWV result. RESULTS: Overall, WP-AHI was moderately correlated to PSG-AHI, but WP-AHI was significantly lower than PSG-AHI (28.4 +/- 19.2 versus 53.6 +/- 30.2 events/h, P < .0001). For the lower PWV group, there was a significant correlation and good agreement between the WP-AHI and PSG-AHI, but as the PWV increased, there was low correlation between the WP-AHI and PSG-AHI. CONCLUSIONS: Arterial stiffness may affect the respiratory variables measured by WatchPAT in patients with OSA. COMMENTARY: A commentary on this article appears in this issue on page 301. PMID- 29458703 TI - A Case of Narcolepsy Type 2 and Postural Tachycardia Syndrome Secondary to Lesions of the Thalamus and Amygdala. AB - ABSTRACT: Although there are reports of narcolepsy type 1 caused by lesions of the central nervous system, there are far fewer reports of narcolepsy type 2 (NT2) caused by discrete brain lesions. We report a case of a patient in whom NT2 was diagnosed after a viral illness, and inflammatory lesions in the right thalamus and amygdala were found. In addition, symptoms of autonomic impairment developed and postural tachycardia syndrome was subsequently diagnosed in this patient. To our knowledge this is the first reported case of NT2 resulting from central nervous system lesions in these discrete locations, as well as the first reported case of postural tachycardia syndrome associated with narcolepsy. PMID- 29458702 TI - The Association Between Insomnia and Sleep Duration in Adults With Attention Deficit Hyperactivity Disorder: Results From a General Population Study. AB - STUDY OBJECTIVES: Insomnia and short or long sleep duration are important comorbid conditions in adults with attention-deficit hyperactivity disorder (ADHD), but reports of the association vary. In a general population study, we evaluated the relationship between ADHD symptom severity, insomnia symptoms, and sleep duration in adults. METHODS: Data were from the third wave of the Netherlands Mental Health Survey and Incidence Study-2 (NEMESIS-2; n = 4,618). ADHD symptom severity and symptom dimensions (hyperactivity and inattention) were assessed using the Adult ADHD Self-Report Scale screener. Self-reported insomnia symptoms (Insomnia Rating Scale; IRS) were defined as clinically relevant if IRS >= 9. Self-reported short sleep duration was defined as <= 6 hours, and long sleep duration as >= 10 hours. RESULTS: Within the group with clinically relevant ADHD symptoms, 43% reported significant insomnia symptoms (odds ratio [OR] = 2.66, 95% confidence interval [CI] 1.74-4.07); 41% short sleep duration (relative risk ratio [RRR] = 1.94, 95% CI 1.31-2.85) and 6% long sleep (RRR = 5.87, 95% CI 1.97-17.45). Increased inattention symptoms were associated with IRS >= 9, short and long sleep duration in fully adjusted models (OR = 1.10, 95% CI 1.06-1.14; RRR = 1.06, 95% CI 1.02-1.09; RRR = 1.16, 95% CI 1.05-1.28, respectively). Increased hyperactivity symptoms were associated with IRS >= 9 (OR = 1.17, 95% CI 1.11-1.23) and short sleep duration (RRR = 1.12, 95% CI 1.05-1.19). CONCLUSIONS: Both clinically significant ADHD symptoms and inattention and hyperactivity symptom dimensions were consistently associated with insomnia symptoms and altered sleep duration. These associations confirm that sleep disturbances should be assessed and given appropriate clinical attention in adults with ADHD. PMID- 29458704 TI - Evaluation of Cardiovascular Risk Factors and Restless Legs Syndrome in Women and Men: A Preliminary Population-Based Study in China. AB - STUDY OBJECTIVES: Many studies have investigated the association between restless legs syndrome (RLS) and cardiovascular risk factors, leading to conflicting results. Therefore, the aim of the current study was to determine whether RLS is associated with cardiovascular risk factors and disease. METHODS: This cross sectional study included 5,324 consecutive subjects who visited the Physical Examination Center of The First Affiliated Hospital of Zhengzhou University for their yearly routine physical examination. Participants underwent a face-to-face interview with a neurologist for the assessment of RLS, based on the International Restless Legs Study Group criteria. They also completed a questionnaire related to cardiovascular risk factors and other health-related and demographic information. Logistic regression was used to assess which of the demographic and cardiovascular risk factors increased the odds of RLS. Then, unadjusted and adjusted models were designed to determine whether RLS was associated with increased odds of cardiovascular disease, coronary artery disease, or hypertension. RESULTS: RLS was observed in 9.2% of the participants. Multivariable logistic regression models, which included the covariates age, sex, body mass index, smoking status, hypercholesterolemia, and Pittsburgh Sleep Quality Index score (dichotomized at 5), demonstrated that female sex (odds ratio [OR]: 2.42, 95% confidence interval [CI]: 1.99-2.95), smoking (OR: 1.96, 95% CI: 1.31-2.92), high cholesterol (OR: 1.30, 95% CI: 1.03-1.64), and PSQI score > 5 (OR: 5.61, 95% CI: 2.14-14.69) are significantly associated with RLS. Additionally, RLS was associated with hypertension, after adjusting for age, sex, body mass index, smoking, hypercholesterolemia, Pittsburgh Sleep Quality Index score > 5, diabetes, anemia, and decreased renal function. CONCLUSIONS: RLS is associated with the prevalence of hypertension but not with that of cardiovascular disease or coronary artery disease. PMID- 29458705 TI - Reliability of the Structured Clinical Interview for DSM-5 Sleep Disorders Module. AB - STUDY OBJECTIVES: To develop and demonstrate interrater reliability for a Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) Sleep Disorders (SCISD). METHODS: The SCISD was designed to be a brief, reliable, and valid interview assessment of adult sleep disorders as defined by the DSM-5. A sample of 106 postdeployment active-duty military members seeking cognitive behavioral therapy for insomnia in a randomized clinical trial were assessed with the SCISD prior to treatment to determine eligibility. Audio recordings of these interviews were double-scored for interrater reliability. RESULTS: The interview is 8 pages long, includes 20 to 51 questions, and takes 10 to 20 minutes to administer. Of the nine major disorders included in the SCISD, six had prevalence rates high enough (ie, n >= 5) to include in analyses. Cohen kappa coefficient (kappa) was used to assess interrater reliability for insomnia, hypersomnolence, obstructive sleep apnea hypopnea (OSAH), circadian rhythm sleep-wake, nightmare, and restless legs syndrome disorders. There was excellent interrater reliability for insomnia (1.0) and restless legs syndrome (0.83); very good reliability for nightmare disorder (0.78) and OSAH (0.73); and good reliability for hypersomnolence (0.50) and circadian rhythm sleep-wake disorders (0.50). CONCLUSIONS: The SCISD is a brief, structured clinical interview that is easy for clinicians to learn and use. The SCISD showed moderate to excellent interrater reliability for six of the major sleep disorders in the DSM-5 among active duty military seeking cognitive behavioral therapy for insomnia in a randomized clinical trial. Replication and extension studies are needed.

AB - For hibernators, being born late in the active season may have important effects on growth and fattening, hence on winter survival and reproduction. This study investigated differences in growth, fattening, energetic responses, winter survival and fecundity between early-born ('EB') and late-born ('LB') juvenile garden dormice (Eliomys quercinus). LB juveniles grew and gained mass twice as fast as EB individuals. Torpor use was low during intensive growth, that are, first weeks of body mass gain, but increased during pre-hibernation fattening. LB juveniles showed higher torpor use, reached similar body sizes but lower fat content than EB individuals before hibernation. Finally, LB individuals showed similar patterns of hibernation, but higher proportion of breeders during the following year than EB dormice. These results suggest that torpor is incompatible with growth but promotes fattening and consolidates pre-hibernation fat depots. In garden dormice, being born late in the reproductive season is associated with a fast life history. PMID- 29458713 TI - Ectomycorrhizal fungi increase the vitality of Norway spruce seedlings under the pressure of Heterobasidion root rot in vitro but may increase susceptibility to foliar necrotrophs. AB - We tested if root colonisation by ectomycorrhizal fungi (EMF) could alter the susceptibility of Norway spruce (Picea abies) seedlings to root rot infection or necrotic foliar pathogens. Firstly, spruce seedlings were inoculated by various EMF and challenged with Heterobasidion isolates in triaxenix tubes. The ascomycete EMF Meliniomyces bicolor, that had showed strong antagonistic properties towards root rot causing Heterobasidion in vitro, protected spruce seedlings effectively against root rot. Secondly, spruce seedlings, inoculated with M. bicolor or the forest humus, were subjected to necrotrophic foliar pathogens in conventional forest nursery conditions on peat substrates. Botrytis cinerea infection after winter was mild and the level of needle damage was independent of substrate and EMF colonisation. Needle damage severity caused by Gremminiella abietina was high in seedlings grown in substrates with high nutrient availability as well as in seedlings with well-established EMF communities. These results show that albeit M. bicolor is able to protect spruce seedlings against Heterobasidion root rot in axenic cultures it fails to induce systemic protection against foliar pathogens. We also point out that unsterile inoculum sources, such as the forest humus, should not be considered for use in greenhouse conditions as they might predispose seedlings to unintended needle damages. PMID- 29458714 TI - Fungal communities associated with species of Fraxinus tolerant to ash dieback, and their potential for biological control. AB - Ash dieback, caused by the fungus Hymenoscyphus fraxineus, has threatened ash trees in Europe for more than two decades. However, little is known of how endophytic communities affect the pathogen, and no effective disease management tools are available. While European ash (Fraxinus excelsior) is severely affected by the disease, other more distantly related ash species do not seem to be affected. We hypothesise that fungal endophytic communities of tolerant ash species can protect the species against ash dieback, and that selected endophytes have potential as biocontrol agents. These hypotheses were tested by isolating members of the fungal communities of five tolerant ash species, and identifying them using ITS regions. Candidate endophytes were tested by an in vitro antagonistic assay with H.fraxineus. From a total of 196 isolates we identified 9 fungal orders, 15 families, and 40 species. Fungi in orders Pleosporales, such as Boeremia exigua and Diaporthe spp., and Hypocreales (e.g., Fusarium sp.), were recovered in most communities, suggesting they are common taxa. The in vitro antagonistic assay revealed five species with high antagonistic activity against H. fraxineus. These endophytes were identified based on ITS region as Sclerostagonospora sp., Setomelanomma holmii, Epicoccum nigrum, B. exigua and Fusarium sp. Three of these taxa have been described previously as antagonists of plant pathogenic microbes, and are of interest for future studies of their potential as biological control agents against ash dieback, especially for valuable ash trees in parks and urban areas. PMID- 29458715 TI - RiArsB and RiMT-11: Two novel genes induced by arsenate in arbuscular mycorrhiza. AB - Plants associated with arbuscular mycorrhizal fungi (AMF) increase their tolerance to arsenic-polluted soils. This study aims to investigate the genes involved in the AMF molecular response to arsenic pollution. Genes encoding proteins involved in arsenic metabolism were identified and their expression assessed by PCR or RT-qPCR. The As-inducible gene GiArsA (R. irregularis ABC ATPase component of the ArsAB arsenite efflux pump) and two new genes, an arsenate/arsenite permease component of ArsAB (RiArsB) and a methyltransferase type 11 (RiMT-11) were induced when arsenate was added to two-compartment in vitro monoxenic cultures of R. irregularis-transformed carrot roots. RiArsB and RiMT-11 expression in extraradical hyphae in response to arsenate displayed maximum induction 4-6 h after addition of 350 MUM arsenate. Their expression was also detected in colonized root tissues grown in pots, or in the root-fungus compartment of two-compartment in vitro systems. We used a Medicago truncatula double mutant (mtpt4/mtpt8) to demonstrate that RiMT-11 and RiArsB transcripts accumulate in response to the addition of arsenate but not in response to phosphate. These results suggest that these genes respond to arsenate addition regardless of non-functional Pi symbiotic transport, and that RiMT-11 may be involved in arsenate detoxification by methylation in AMF-colonized tissues. PMID- 29458716 TI - Selection is required for efficient Cas9-mediated genome editing in Fusarium graminearum. AB - Genome engineering using Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-associated nucleases, such as Cas9 (CRISPR-associated protein 9), are revolutionising molecular biology. In this study, we established a Cas9 based genome editing system in Fusarium graminearum, a highly destructive fungal pathogen of cereal crops. Although the molecular toolkit of F. graminearum is well developed compared to other fungi, Cas9-mediated engineering offers a number of potential benefits, such as the ability to create marker free mutants in this species. Here we have used a codon-optimised Cas9 nuclease and dual ribozyme based expression of a single guide RNA (sgRNA) to induce mutations. Cas9-mediated mutations were identified through a fungicide resistance-based phenotypic screen, which selects for null mutations in the FgOs1 gene encoding an osmosensor histidine kinase. In the absence of selection, however, mutations were identified at very low frequency. Examination of the mutant alleles identified suggests that, a microhomology-mediated end joining (MMEJ) DNA repair pathway is likely to be the predominant process involved in erroneous repairing of Cas9-induced double stranded breaks in F. graminearum.

AB - Herbarium specimens are a treasure trove for biochemical studies. However, this implies understanding of the chemical changes during the drying and storage of the specimen. We compared herbarium specimens at different ages and fresh samples of four mushroom species (Kuehneromyces mutabilis, Hypholoma capnoides, Kuehneromyces lignicola, Hypholoma fasciculare) of two genera in the family Strophariaceae by using proton nuclear magnetic resonance (1H NMR) spectroscopy combined with principal component analysis (PCA). 25 metabolites were identified. No significant alterations were found between herbarium samples at different ages, suggesting that they are stable enough for comparative studies. The most dominant differences between fresh and herbarium samples was that sugars such as alpha-alpha-trehalose, and fumaric and malic acids were more abundant in fresh fungi. Total contents of fatty and amino acids, uracil and gamma-aminobutyric acid (GABA) were higher in herbarium specimens. In addition, pyroglutamic acid was observed only in Kuehneromyces mutabilis and fasciculic acid E in Hypholomafasciculare. Hence, based on results of the studied taxa, we conclude that NMR metabolomics can be used for both fresh and dried mushrooms when such alterations are properly addressed. PMID- 29458718 TI - Frequent diploidisation of haploid Armillaria ostoyae strains in an outdoor inoculation experiment. AB - Very little is known about the biology and ecology of haploid Armillaria strains in nature. In this outdoor inoculation experiment, we assessed the virulence of six haploid Armillariaostoyae strains along with their diploid parent towards 2 year-old seedlings and 4-year-old saplings of Norway spruce (Picea abies), and determined their ability to colonise freshly cut stumps. As inoculum source an Armillaria-colonised hazelnut (Corylus avellana) stem segment was inserted into the soil substrate. Re-isolations from mycelial fans at the root collar of infected trees or stumps were made. Surprisingly, not a single haploid re-isolate could be recovered. Microsatellite genotyping of 133 re-isolates suggests that the inoculated haploid strains were diploidised either by mating propagules (basidiospores or haploid mycelia) already present in the soil substrate or naturally disseminated in the course of the experiment from nearby forests. Consequently, no conclusion about the infectious ability of haploid Armillaria mycelia under natural conditions can be drawn. Nonetheless, the diploid half-sib families resulting from the diploidisation showed varying degrees of virulence, with a high correlation between the experiment with 2-year-old seedlings and 4 year-old saplings. Despite extensive genotyping of re-isolates, no evidence for somatic recombination between haploid mating propagules and diploidised mycelia was detected, suggesting that this is an uncommon phenomenon in A. ostoyae.

In this study, continuous subculturing of B. bassiana on both rice grains and potato dextrose agar (PDA) resulted in 55 and 49 % conidial yield reduction after 12 passages and 68 and 60 % virulence reduction after 20 and 12 passages at four d post-inoculation, respectively. The passage through Tenebrio molitor and Spodoptera exigua restored the virulence of rice and PDA subcultures, respectively. To explore the molecular mechanisms underlying the conidial quality and the decline of virulence after multiple subculturing, we investigated the conidial proteomic changes. Successive subculturing markedly increased the protein levels in oxidative stress response, autophagy, amino acid homeostasis, and apoptosis, but decreased the protein levels in DNA repair, ribosome biogenesis, energy metabolism, and virulence. The nitro blue tetrazolium assay verified that the late subculture's colony and conidia had a higher oxidative stress level than the early subculture. A 2A-type protein phosphatase and a Pleckstrin homology domain protein Slm1, effector proteins of the target of rapamycin (TOR) complex 1 and 2, respectively, were dramatically increased in the late subculture. These results suggest that TOR signalling might be associated with ageing in B. bassiana late subculture, in turn affecting its physiological characteristics and virulence. PMID- 29458720 TI - Metabolite production by species of Stemphylium. AB - Morphology and phylogeny have been used to distinguish members of the plant pathogenic fungal genus Stemphylium. A third method for distinguishing species of fungi is by chemotaxonomy. The main goal of the present study was to investigate the chemical potential of Stemphylium via HPLC-UV-MS analysis, while also exploring the potential of chemotaxonomy as a robust identification method for Stemphylium. Several species were found to have species-specific metabolites, while other species were distinguishable by a broader metabolic profile rather than specific metabolites. Many previously described metabolites were found to be important for distinguishing species, while some unknown metabolites were also determined to have important roles in distinguishing species of Stemphylium. This study is the first of its kind to investigate the chemical potential of Stemphylium across the whole genus. PMID- 29458722 TI - Molecular phylogeny of the Laboulbeniomycetes (Ascomycota). AB - A first molecular-based phylogeny is presented for the Laboulbeniomycetes, a group of ascomycete fungi that utilize arthropods for nutrition and/or dispersal. Morphological diversification and life-history evolution has made it difficult to resolve relationships within the group, and to identify close relatives. Here, we infer a preliminary phylogeny based on acquisition of 51 new SSU rDNA sequences, representing a total of 65 taxa. The results of this study demonstrate that Laboulbeniomycetes is monophyletic, and related to Sordariomycetes. The class could be divided into at least 4 or 5 orders, though we refrain from formally giving names to these at this stage. Further evidence for the occurrence of asexuality within the class is provided by the inclusion of the genera Chantransiopsis and Tetrameronycha, both known only as asexual taxa with thalli consisting of linearly superposed cells. The precise placement of the genus Herpomyces (Herpomycetaceae), on cockroaches, remains unresolved in our analysis, but lies outside of the main clade of sexually reproducing Laboulbeniales. There is good support for this latter grouping, comprising taxa that are found on both aquatic and terrestrial hosts. Within this large assemblage, we recognize 5 distinct clades (clades E, F, G, H, I). Relationships among the so-called "aquatic genera" (= Ceratomycetaceae + some Euceratomycetaceae and Zodiomyces) are poorly resolved in our analyses, accounting for 3 of these clades (E, F, G), with the remainder of the taxa (largely equivalent to Laboulbeniaceae) split into two major groupings (clades H, I). Across all taxa, antheridial characteristics, features on which the earliest classifications were based, are shown to be homoplastic. On the other hand, features of perithecial development show an overall trend towards reduction, and appear to be phylogenetically informative. Morphological characters are identified that support the dichotomy in the Laboulbeniaceae and subclades within the two major groupings are discussed further in light of information on thallus morphology, development, and host relationships.

PMID- 29458721 TI - Galleria melonella as an experimental in vivo host model for the fish-pathogenic oomycete Saprolegnia parasitica. AB - Oomycetes are eukaryotic pathogens infecting animals and plants. Amongst them Saprolegnia parasitica is a fish pathogenic oomycete causing devastating losses in the aquaculture industry. To secure fish supply, new drugs are in high demand and since fish experiments are time consuming, expensive and involve animal welfare issues the search for adequate model systems is essential. Galleria mellonella serves as a heterologous host model for bacterial and fungal infections. This study extends the use of G. mellonella for studying infections with oomycetes. Saprolegniales are highly pathogenic to the insects while in contrast, the plant pathogen Phytophthora infestans showed no pathogenicity. Melanisation of hyphae below the cuticle allowed direct macroscopic monitoring of disease progression. However, the melanin response is not systemic as for other pathogens but instead is very local. The mortality of the larvae is dose dependent and can be induced by cysts or regenerating protoplasts as an alternative source of inoculation. PMID- 29458724 TI - The Evolving Spectrum of the Epidemiology of Thalassemia. AB - The thalassemias and other inherited disorders of hemoglobin are likely to remain a serious global health problem for the foreseeable future. Currently, they are most frequent in the tropical belt; an assessment of their true frequency and the likely cost of management for the governments of these countries will require a form of micromapping. Over recent years, there has been major progress toward better prevention and management of the thalassemias in richer countries; it is likely that, using the tools of molecular genetics, they will eventually be completely curable, although this is probably a long time in the future. PMID- 29458725 TI - Molecular Basis and Genetic Modifiers of Thalassemia. AB - Thalassemia is a disorder of hemoglobin characterized by reduced or absent production of one of the globin chains in human red blood cells with relative excess of the other. Impaired synthesis of beta-globin results in beta thalassemia, whereas defective synthesis of alpha-globin leads to alpha thalassemia. Despite being a monogenic disorder, thalassemia exhibits remarkable clinical heterogeneity that is directly related to the intracellular imbalance between alpha- and beta-like globin chains. Novel insights into the genetic modifiers have contributed to the understanding of the correlation between genotype and phenotype and are being explored as therapeutic pathways to cure this life-limiting disease. PMID- 29458726 TI - Clinical Classification, Screening and Diagnosis for Thalassemia. AB - At present, thalassemia diseases are classified into transfusion-dependent thalassemia and non-transfusion-dependent thalassemia. This classification is based on the clinical severity of patients determining whether they do require regular blood transfusions to survive (transfusion-dependent thalassemia) or not (non-transfusion-dependent thalassemia). In addition to the previous terminology of "thalassemia major" or "thalassemia intermedia," this classification has embraced all other forms of thalassemia syndromes such as alpha-thalassemia, hemoglobin E/beta-thalassemia and combined alpha- and beta-thalassemias. Definitive diagnosis of thalassemia and hemoglobinopathies requires a comprehensive workup from complete blood count, hemoglobin analysis, and molecular studies to identify mutations of globin genes. PMID- 29458728 TI - Clinical Complications and Their Management. AB - The hallmarks of thalassemias are ineffective erythropoiesis and peripheral hemolysis leading to a cascade of events responsible for several clinical complications. This pathophysiologic mechanism can be partially controlled by blood transfusions or by correction of the severity of ineffective erythropoiesis. Thalassemias include a spectrum of phenotypes. Two main groups can be clinically distinguished: transfusion-dependent (TDT) and non-transfusion dependent (NTDT) thalassemia. Both conditions are characterized by several clinical complications along life; some are shared, whereas some have higher prevalence in one group over the other. The authors present the most common clinical complications in TDT and NTDT and their management. PMID- 29458727 TI - Ineffective Erythropoiesis: Anemia and Iron Overload. AB - Stress erythropoiesis (SE) is characterized by an imbalance in erythroid proliferation and differentiation under increased demands of erythrocyte generation and tissue oxygenation. beta-thalassemia represents a chronic state of SE, called ineffective erythropoiesis (IE), exhibiting an expansion of erythroid progenitor pool and deposition of alpha chains on erythrocyte membranes, causing cell death and anemia. Concurrently, there is a decrease in hepcidin expression and a subsequent state of iron overload. There are substantial investigative efforts to target increased iron absorption under IE. There are also avenues for targeting cell contact and signaling within erythroblastic islands under SE, for therapeutic benefits. PMID- 29458729 TI - Hypercoagulability and Vascular Disease. AB - The presence of a high incidence of thrombotic events, mainly in nontransfusion dependent beta-thalassemia syndromes, has led to the identification of a hypercoagulable state in thalassemia patients. This article highlights the mechanisms leading to hypercoagulability in thalassemia. It also discusses the clinical experience and available evidence on prevention and management approaches. PMID- 29458730 TI - Interaction of Transfusion and Iron Chelation in Thalassemias. AB - The relationship between blood transfusion intensity, chelatable iron pools, and extrahepatic iron distribution is described in thalassemia. Risk factors for cardiosiderosis are discussed with particular reference to the balance of transfusional iron loading rate and transferrin-iron utilization rate as marked by plasma levels of soluble transferrin receptors. Low transfusion regimens increase residual erythropoiesis allowing for apotransferrin-dependent clearance of non-transferrin-bound iron species otherwise destined for myocardium. The impact of transfusion rates on chelation dosing required for iron balance is also shown. PMID- 29458731 TI - Iron Chelation Therapy as a Modality of Management. AB - Introduction of MRI techniques for identifying and monitoring tissue iron overload and the current understanding of iron homeostasis in transfusion dependent (TDT) and non-transfusion-dependent thalassemia have allowed for a more robust administration of iron chelation therapies. The development of safe and efficient oral iron chelators and the insights gained from large-scale prospective studies using these agents have improved iron overload management. A significant reduction in iron toxicity-induced morbidity and mortality and improvements in quality of life were observed in TDT. The appropriate management of tissue-specific iron loading in TDT has been portrayed using evidence-based data obtained from investigational studies. PMID- 29458732 TI - MRI for Iron Overload in Thalassemia. AB - MRI is a key tool in the current management of patients with thalassemia. Given its capability of assessing iron overload in different organs noninvasively and without contrast, it has significant advantages over other metrics, including serum ferritin. Liver iron concentration can be measured either with relaxometry methods T2*/T2 or signal intensity ratio techniques. Myocardial iron can be assessed in the same examination through T2* imaging. In this review, we focus on showing how MRI evaluates iron in both organs and the clinical applications as well as practical approaches to using this tool by clinicians taking care of patients with thalassemia. PMID- 29458733 TI - Fertility and Pregnancy in Women with Transfusion-Dependent Thalassemia. AB - As more women with transfusion-dependent thalassemia are seeking pregnancy, ensuring the best outcomes for both the mother and baby requires concerted, collaborative efforts between practitioners and the family. Proactive counseling, early fertility evaluation, recent developments in reproductive technology, and optimal management of iron overload, have resulted in more successful pregnancies and the birth of healthy newborns. With advances in technology for prenatal screening and increased awareness to perform screening for hemoglobinopathies, healthy pregnancy outcomes have become the expectation. Topics that require further study include management that allows fertility preservation, improved non invasive prenatal diagnosis methods for affected fetuses, the use of chelation therapy during pregnancy, and indications for and duration of anticoagulation. PMID- 29458734 TI - Hematopoietic Stem Cell Transplantation in Thalassemia. AB - Although recent advances in gene therapy are expected to increase the chance of disease cure in thalassemia major, at present hematopoietic stem cell transplantation (HSCT) remains the only consolidated curative approach for this disorder. The widest experience has been obtained in the HLA-matched family donor (MFD) setting, with probabilities of overall and thalassemia-free survival exceeding 90% and 85%, respectively. As for most patients a suitable MFD is not available, alternative donors (HLA-matched unrelated donor, unrelated cord blood, HLA-haploidentical relative) have been increasingly explored, translating into the expansion of the number of patients treatable with HSCT. PMID- 29458735 TI - Gene Therapy and Genome Editing. AB - The beta-thalassemias are inherited blood disorders that result from insufficient production of the beta-chain of hemoglobin. More than 200 different mutations have been identified. beta-Thalassemia major requires life-long transfusions. The only cure for severe beta-thalassemia is to provide patients with hematopoietic stem cells. Globin gene therapy promises a curative autologous stem cell transplantation without the immunologic complications of allogeneic transplantation. The future directions of gene therapy include enhancement of lentiviral vector-based approaches, fine tuning of the conditioning regimen, and the design of safer vectors. Progress in genetic engineering bodes well for finding a cure for severe globin disorders. PMID- 29458737 TI - Erratum. PMID- 29458738 TI - Thalassemia. PMID- 29458736 TI - Emerging Therapies. AB - At present, the only definitive cure for beta-thalassemia is a bone marrow transplant (BMT); however, HLA-blood-matched donors are scarcely available. Current therapies undergoing clinical investigation with most potential for therapeutic benefit are the beta-globin gene transfer of patient-specific hematopoietic stem cells followed by autologous BMT. Other emerging therapies deliver exogenous regulators of several key modulators of erythropoiesis or iron homeostasis. This review focuses on current approaches for the treatment of hemoglobinopathies caused by disruptions of beta-globin. PMID- 29458739 TI - ? PMID- 29458740 TI - Sensitivity and specificity of Frontal Assessment Battery in newly diagnosed and untreated obstructive sleep apnea patients. AB - BACKGROUND: Executive dysfunction (ED) is often observed in subjects diagnosed with obstructive sleep apnea (OSA), but their assessment requires facilities that are not always available. We aim to evaluate the extent to which Frontal Assessment Battery (FAB) discriminates ED in newly diagnosed, untreated, and without-comorbidity OSA patients. METHODS: Sixty subjects participated in the study. Of these, 40 (31 males and 9 females) were newly diagnosed for OSA through full-night polysomnography (apnea/hypopnea index; M = 39.01, SD = 27.16), untreated, with a mean age of 54.50 years (SD = 8.90), while the remaining 20 (15 males and 5 females) had no symptoms of OSA (M = 51.60 years, SD = 10.70). The instruments used were the following: Questionnaire for Sleep Apnea Risk, Epworth Sleepiness Scale, Mini-Mental State Examination, and FAB. RESULTS: The group with OSA exhibited significantly lower values in the FAB global score (p = 0.003) and in Conceptualization (p = 0.001) and Mental Flexibility (p = 0.009) subtests. ROC analysis showed adequate discriminative capacity for the FAB global score (AUC = 0.74) and for Conceptualization (AUC = 0.75) and Mental Flexibility (AUC = 0.70) scores. CONCLUSIONS: The FAB is a short and no-time-consuming tool that can be used to investigate the presence of ED in untreated OSA patients with no comorbidities, providing clinicians with a simple and effective way of detecting the presence of this dysfunction and allowing a more informed decision for the need of a full neuropsychological assessment. PMID- 29458741 TI - Sleep-disordered breathing is associated with disturbed cardiac repolarization in patients with a coronary artery bypass graft surgery. AB - BACKGROUND: The development of malignant ventricular arrhythmias due to abnormal cardiac repolarization is a major complication after coronary artery bypass graft surgery (CABG). Sleep-disordered breathing (SDB) is linked to prolonged cardiac repolarization in non-surgical patients. This study evaluates cardiac repolarization in patients with and without SDB who underwent CABG. METHODS: 100 patients who had received CABG (84% men, age 68 +/- 10 years, body-mass-index [BMI] 28.7 +/- 4.2 kg/m2) were retrospectively evaluated. Polygraphy was recorded the night before CABG. SDB was defined as an apnea-hypopnea index (AHI) of >=15/h and differentiated into central (CSA) and obstructive (OSA) sleep apnea. Cardiac repolarization was assessed by means of T-peak-to-end (TpTe) and QTc-intervals and TpTe/QT-ratios derived from 12-lead electrocardiography (ECG). RESULTS: 37% of patients had SDB, 14% CSA and 23% OSA. Before CABG, patients with CSA and OSA had longer TpTe intervals than those without SDB (TpTe: CSA 100 +/- 26 vs. OSA 97 +/- 19 vs. no SDB 85 +/- 14 ms, p = 0.013). QTc intervals and TpTe/QT ratios differed between the two groups (QTc: 444 +/- 54 vs. 462 +/- 36 vs. 421 +/- 32 ms, p < 0.001; TpTe/QT ratio: 0.24 +/- 0.04 vs. 0.23 +/- 0.05 vs. 0.21 +/- 0.03, p = 0.045). SDB was associated with abnormal cardiac repolarization independent of known risk factors for cardiac arrhythmias, such as age, sex, BMI, N-terminal pro-brain-natriuretic-peptide (NT-proBNP), and heart failure (TpTe: B-coefficient [95%CI]: 16.0, [7.6-24.3], p < 0.001; QTc: 27.2 [9.3-45.1], p = 0.003; TpTe/QT ratio: 2.9 [1.2-4.6], p < 0.001). CONCLUSION: Independent of known risk factors for cardiac arrhythmias, SDB was significantly associated with abnormal cardiac repolarization before CABG. Data suggest that SDB may contribute to an increased risk of ventricular arrhythmias after CABG. PMID- 29458742 TI - Preserved sleep microstructure in blind individuals. AB - The loss of vision, particularly when it occurs early in life, is associated with compensatory cortical plasticity not only in the visual cortical areas, but throughout the entire brain. The absence of visual input to the retina can also induce changes in entrainment of the circadian rhythm, as light is the primary zeitgeber of the master biological clock found in the suprachiasmatic nucleus of the hypothalamus. In addition, a greater number of sleep disturbances is often reported in blind individuals. Here, we examined various electroencephalographic microstructural components of sleep, both during rapid-eye-movement (REM) sleep and non-REM (NREM) sleep, between blind individuals, including both of early and late onset, and normal-sighted controls. During wakefulness, occipital alpha oscillations were lower, or absent in blind individuals. During sleep, differences were observed across electrode derivations between the early and late blind samples, which may reflect altered cortical networking in early blindness. Despite these differences in power spectra density, the electroencephalography microstructure of sleep, including sleep spindles, slow wave activity, and sawtooth waves, remained present in the absence of vision. PMID- 29458743 TI - Sleep disturbance as a predictor of time to drug and alcohol use treatment in primary care. AB - BACKGROUND: Sleep Disturbances (SDs) are a symptom common to mental health disorders (MHD) and substance use disorders (SUD). We aimed to identify the value of SD as a predictor for subsequent treatment of illicit drug and alcohol use disorders (SUDs) in primary care and relative to the predictive value of mental health disorders (MHDs). METHODS: We used electronic health records data from ambulatory primary care in a safety net Boston area healthcare system from 2013 to 2015 (n = 83,920). SUD (separated into illicit drug use disorder and alcohol use disorder) and MHD were identified through ICD-9 codes and medical record documentation. We estimated Cox proportional hazard models to examine the risk of SUD across four comparison groups (SD only, SD and MHD, MHD only, and neither SD nor MHD). RESULTS: Compared to patients with no sleep or MHD, patients with SD had a greater risk for subsequent SUD treatment. Approximately one-fifth of patients with SD were treated for an illicit drug use disorder and approximately 12% were treated for alcohol use disorder. Risk for SUD treatment, estimated at over 30% by the end of the study, was greatest for patients with a MHD, either alone or comorbid with SD. Risk was greater for older patients and men, and lower for minority patients. CONCLUSIONS: SD and MHD, individually and comorbid, significantly predict subsequent treatment of illicit drug and alcohol use disorder in primary care. Screening and evaluation for SD should be a routine practice in primary care to help with identifying potential SUD risk. PMID- 29458745 TI - Sleep duration independently influences metabolic body size phenotype in children and adolescents: a population-based study. AB - BACKGROUND: Epidemiologic studies have found an association between sleep duration and obesity. However, the relationship between sleep duration and metabolic body size phenotype in children and adolescents remains unknown. METHODS: In this cross-sectional study, 3650 participants (1946 boys and 1704 girls) from the Korean National Health and Nutrition Examination Survey 2007-2012 were classified into four phenotypes according to body mass index and metabolic heath status based on the definition of metabolic syndrome by NCEP-ATP III or the International Diabetes Federation. The four phenotypes were: metabolically healthy normal weight (MHNW), metabolically unhealthy normal weight (MUNW), metabolically healthy overweight (MHO), and metabolically unhealthy overweight (MUO). The associations between the four metabolic body size phenotypes and sleep duration, categorized as very short (<=5 h), short (6-7 h), normal (8-10 h), or long (>=11 h), were evaluated. RESULTS: Sleep duration was shorter in the MUO group (7.0 +/- 1.5 h) than in the MHNW (7.3 +/- 1.4 h) or MUNW (7.8 +/- 1.6 h) groups. After adjusting for age, sex, household income, and physical activity, compared with a normal sleep duration, very short sleep duration (<=5 h) was associated with a higher prevalence of being overweight/obese (26.4% vs 17.4%, p = 0.001), lower risk of being MHNW (0.711 (0.538-0.940), p = 0.017) or MUNW (0.478 (0.237-0.962), p = 0.039), and higher risk of being MHO (1.702 (1.193 2.428), p = 0.003). By contrast, long sleep duration (>=11 h) was associated with a higher risk of being MUNW (2.581 (1.124-5.928), p = 0.025). CONCLUSIONS: Sleep duration may be independently associated with metabolic body size phenotype in children and adolescents. PMID- 29458744 TI - Alcohol and the risk of sleep apnoea: a systematic review and meta-analysis. AB - OBJECTIVE: A systematic review and meta-analysis of the association between alcohol consumption and risk of sleep apnoea in adults. METHODS: We searched Medline, EMBASE and Web of Science databases from 1985 to 2015 for comparative epidemiological studies assessing the relation between alcohol consumption and sleep apnoea. Two authors independently screened and extracted data. Random effects meta-analysis was used to estimate pooled effect sizes with 95% confidence intervals (CI). Heterogeneity was quantified using I2 and explored using subgroup analyses based on study exposure and outcome measures, quality, design, adjustment for confounders and geographical location. Publication bias was assessed using a funnel plot and Egger's test. RESULTS: We identified 21 studies from which estimates of relative risk could be obtained. Meta-analysis of these estimates demonstrated that higher levels of alcohol consumption increased the risk of sleep apnoea by 25% (RR 1.25, 95%CI 1.13-1.38, I2 = 82%, p < 0.0001). This estimate's differences were robust in alcohol consumption and sleep apnoea definitions, study design, and quality but was greater in Low and Middle Income Country locations. We detected evidence of publication bias (p = 0.001). A further eight included studies reported average alcohol consumption in people with and without sleep apnoea. Meta-analysis revealed that mean alcohol intake was two units/week higher in those with sleep apnoea, but this difference was not statistically significant (p = 0.41). CONCLUSION: These findings suggest that alcohol consumption is associated with a higher risk of sleep apnoea, further supporting evidence that reducing alcohol intake is of potential therapeutic and preventive value in this condition. PMID- 29458746 TI - Stridor combined with other sleep breathing disorders in multiple system atrophy: a tailored treatment? AB - OBJECTIVES: To determine the frequency of sleep breathing disorders in multiple systemic atrophy (MSA, combining Parkinsonism, cerebellar syndrome, and dysautonomia) and evaluate the benefit/tolerance of various modes of ventilation. METHODS: We retrospectively analyzed 45 patients with MSA having undergone a videopolysomnography. Their sleep characteristics were compared to those of 45 patients with Parkinson's disease and 45 healthy controls, matched for age and sex. Patients with MSA received fixed continuous positive airway pressure (CPAP) when stridor was isolated, auto-adjusting CPAP when it was combined with obstructive sleep apnea, and adaptive servo-ventilation (ASV) when combined with central sleep apnea. RESULTS: Higher periodic leg movements index and more frequent REM sleep behavior disorder were observed in MSA patients, compared to patients with Parkinson's disease and healthy controls. In MSA, 28/45 (62.2%) patients had sleep breathing disorders, including (overlapping samples) stridor (n = 17, 38%), obstructive sleep apnea (n = 14, 31%), central sleep apnea (n = 4, 9%), and ataxic breathing (n = 1). Except for three initial refusals and two yet untreated patients, fixed CPAP (n = 9), auto-adjusting CPAP (n = 8) and ASV (n = 2) were well-tolerated (limited leaks and good compliance) and successfully controlled stridor plus sleep apnea. Treated patients had survival times similar to those of patients without any sleep breathing disorder. CONCLUSION: In this small group, tailored management of stridor in MSA as an independent issue or combined with obstructive and central sleep apnea, yields a survival similar to survival in patients without sleep breathing disorders. PMID- 29458747 TI - Sex-specific associations between extreme sleep duration and prevalence of cardio cerebral vascular disease: a community-based cross-sectional study. AB - BACKGROUND: Most previous studies on sleep duration and cardio-cerebral vascular disease (CCVD) association have not adequately controlled for many confounders. The current study prospectively examined the association of sleep duration with CCVD prevalence in a Chinese community population; cardiovascular risk factors, chronic diseases, and sleep quality were taken into consideration. METHODS: A cross-sectional study conducted in Pudong New Area of Shanghai, China. Through three-stage sampling, 10,657 adults aged >=15 years were randomly selected. Self reported sleep duration and CCVD prevalence were obtained using a structured questionnaire. Medical records of the subjects were reviewed by investigators for further confirmation. Relationships between sleep duration and CCVD prevalence were examined using logistic regression models. RESULTS: Compared to midrange sleep duration (7 h), the multivariate-adjusted OR of CCVD prevalence was 1.550 (95% CI 1.192-2.017) for sleeping 5 h, 1.427 (95% CI 0.983-2.072) for sleeping <5 h. A similar situation also prevailed in coronary heart disease (CHD) prevalence: the multivariate-adjusted OR of stroke prevalence was 2.130 (95% CI 1.338-3.389) for sleeping >9 h. In an analysis stratified by sex, participants with a long sleep duration (>9 h) demonstrated significantly increased prevalence (OR = 3.623, 95% CI 1.862-7.052) for stroke only in men. CONCLUSIONS: The relationship between extreme sleep durations and CCVD were influenced by sex in a Chinese community population. Further studies are needed to investigate the mechanisms of the association between extreme sleep duration and CCVD, as well as sex specificity in the relationship. PMID- 29458748 TI - Does continuous positive airway pressure treatment affect autonomic nervous system in patients with severe obstructive sleep apnea? AB - OBJECTIVE: This study is aimed at evaluating whether Continuous Positive Airway Pressure treatment (CPAP) may affect autonomic nervous system (ANS) in male patients with severe obstructive sleep apnea (OSAS). METHODS: We compared autonomic symptoms of de novo severe OSAS patients, OSAS patients on chronic CPAP treatment and healthy controls, using the Scales for Outcome in Parkinson disease Autonomic (SCOPA-AUT) questionnaire. All groups underwent cardiovascular function tests including head-up tilt test (HUTT), Valsalva maneuver, deep breathing, hand grip and cold face tests. Statistical significance was set at p < 0.05. RESULTS: Twelve de novo severe OSAS patients, 17 male OSAS on CPAP and 14 controls were studied. The mean SCOPA-AUT total score was significantly higher in de novo OSAS patients compared with controls. Regarding the distinct domains, both de novo OSAS and CPAP group had abnormalities in respect of controls in urinary sphere. In supine rest condition the baseline values of systolic blood pressure were significantly increased in untreated OSAS patients compared with controls, whereas the basal values of diastolic blood pressure were significantly higher in CPAP patients with respect to controls. After ten min of HUTT, diastolic blood pressure changes were significantly higher in controls compared to both OSAS groups. Untreated OSAS patients showed significant different responses at deep breathing compared to controls. Both OSAS groups had a significant reduction of reflex bradycardia at cold face test. CONCLUSIONS: Our study shows that both treated and untreated OSAS patients complain of subjective autonomic symptoms like other sleep disorders reinforcing the close relationship between sleep and autonomic activity. Furthermore, cardiovascular reflexes indicate a tendency to hypertension and a reduced sensitivity to stimuli during wakefulness even in OSA patients on CPAP treatment, suggesting potentially permanent autonomic function deficits. PMID- 29458749 TI - Efficacy of ferric carboxymaltose (FCM) 500 mg dose for the treatment of Restless Legs Syndrome. AB - INTRODUCTION: There have been four randomized, placebo-controlled, double-blinded studies of intravenous (IV) iron in Restless Legs Syndrome (RLS), all of which delivered a final total dose of 1000 mg of iron. The purpose of this study was to evaluate effects of a lesser total dose (500 mg of iron). METHODS: Subjects with idiopathic RLS were enrolled in a randomized, double-blinded, placebo-controlled study. Subjects received either 500 mg ferric carboxymaltose (FCM) or placebo as a single infusion (Phase I). Subjects who were previously on medication were off any RLS medications for at least two weeks prior to baseline assessment. The primary outcome variable was a change-from-baseline at week six on the International RLS Severity Scale (IRLSS) and a subject-completed Visual Analog Scale of Severity (VAS). Phase II of the study involved long-term (30 weeks) follow-up after completing the six week efficacy phase. RESULTS: At week six post infusion, FCM, compared to placebo recipients, showed no significantly greater change-from-baseline for both primary outcome measures (IRLSS scale, FCM 500 mg vs. placebo: -8.3 +/- 7.5 vs. -4.8 +/- 8.7, p = 0.100; VAS, FCM 500 mg vs. placebo: -23.4 +/- 24.1 vs. -13.3 +/- 23.1, p = 0.077). None of the secondary outcome variables showed a significant difference at week six. Seven (21.9%) of the 32 subjects treated with iron in Phase I remained free from further RLS medications at 30 weeks. No serious adverse effects were found in this study. CONCLUSIONS: This study did not show significant benefit from a single 500 mg FCM treatment for RLS symptoms. The two previous, well-controlled, trials of 1000 mg FCM showed significant treatment benefits which suggested that there may have been a clinically relevant total dose required to achieve a clinical response. PMID- 29458750 TI - Different maturational changes of fast and slow sleep spindles in the first four years of life. AB - OBJECTIVE/BACKGROUND: Massive changes in brain morphology and function in the first years of life reveal a postero-anterior trajectory of cortical maturation accompanied by regional modifications of NREM sleep. One of the most sensible marker of this maturation process is represented by electroencephalographic (EEG) activity within the frequency range of sleep spindles. However, direct evidence that these changes actually reflect maturational modifications of fast and slow spindles still lacks. Our study aimed at answering the following questions: 1. Do cortical changes at 11.50 Hz frequency correspond to slow spindles? 2. Do fast and slow spindles show different age trajectories and different topographical distributions? 3. Do changes in peak frequency explain age changes of slow and fast spindles? PATIENTS/METHODS: We measured the antero-posterior changes of slow and fast spindles in the first 60 min of nightly sleep of 39 infants and children (0-48 mo.). RESULTS: We found that (A) changes of slow spindles from birth to childhood mostly affect frontal areas (B) variations of fast and slow spindles across age groups go in opposite direction, the latter progressively increasing across ages; (C) this process is not merely reducible to changes of spindle frequency. CONCLUSIONS: As a main finding, our cross-sectional study shows that the first form of mature spindle (i.e., corresponding to the adult phasic event of NREM sleep) is marked by the emergence of slow spindles on anterior regions around the age of 12 months. PMID- 29458751 TI - Somatosensory function is impaired in patients with idiopathic REM sleep behaviour disorder. AB - BACKGROUND: Idiopathic REM sleep behaviour disorder (iRBD) has been recognised as a significant biomarker for developing a neurodegenerative alpha-synucleinopathy, which is why iRBD is considered to be a prodromal state for alpha synucleinopathies including Parkinson's disease (PD). Many patients with PD suffer from complaints of pain and present impaired somatosensory function. We hypothesized that pain perception and somatosensory function could be altered already in a preclinical stage of PD including iRBD. Hence, the objective of this study was to investigate pain perception and somatosensory function in patients with iRBD. METHODS: Quantitative sensory testing (QST), laser evoked potentials (LEPs), and conditioned pain modulation (CPM) testing were performed in 13 iRBD patients without any clinical signs of PD or narcolepsy (11 males, 2 females, mean age 65.2 years) and 15 gender- and age-matched healthy control subjects (12 males, 3 females, mean age 65.8 years). RESULTS: Thermal detection thresholds were higher in the iRBD group compared with the control group (cold detection threshold (CDT) p = 0.020, thermal sensory limen (TSL) p = 0.001), indicating an impaired temperature sensation in iRBD patients. The N2/P2 LEPs amplitude was smaller in iRBD patients than controls, but not statistically significant (p = 0.053). CONCLUSIONS: This study found an impaired somatosensory function in iRBD patients, suggesting that somatosensory impairment might be an early feature in the neurodegenerative process of PD. PMID- 29458752 TI - A survey on sleep questionnaires and diaries. AB - Sleep assessment is a fundamental part of health evaluation. In fact, many diseases (such as obesity, diabetes, or hypertension, as well as psychiatric, neurological, and cardiovascular diseases) produce sleep disorders that are often used as indicators, diagnosis (symptoms), or even as predictors (eg, for depression) of health. For this reason, many efforts have been devoted to designing methods to control and report on sleep quality. Two of the most used sleep assessment tools are sleep questionnaires and sleep diaries. Both methods have a very low cost are easy to administer do not require a sleep centre (unlike, eg, polysomnography), and can be self-administered. Most important, as it has been shown in recent studies, their accuracy is relatively high. In this survey, we systematically review and compare these tools. We examine the evolution of sleep questionnaires and diaries over time, and compare their structure and usage. We also review the validation studies and comparatives performed in previous studies. This allows us to compare the relative sensitivities and specificities of these methods. Modern sleep diaries come in the form of an app. Therefore, we also present the most advanced and used apps, and discuss their advantages over classical paper diaries. PMID- 29458753 TI - Challenges in sleep stage R scoring in patients with autosomal dominant spinocerebellar ataxias (SCA1, SCA2 and SCA3) and oculomotor abnormalities: a whole night polysomnographic evaluation. AB - OBJECTIVES: Spinocerebellar ataxias are progressive neurodegenerative disorders characterized by progressive cerebellar features with additional neuro-axis involvement. Oculomotor abnormality is one of the most frequent manifestations. This study was done to assess the polysomnographic abnormalities in patients with Spinocerebellar ataxia (SCA1, SCA2 and SCA3) and also to evaluate whether oculomotor abnormalities interfere with sleep stage R scoring. METHODS: The study was carried out using 36 genetically positive SCA patients. All patients underwent neurological examination with special focus on oculomotor function (optokinetic nystagmus-OKN and extraocular movement restriction-EOM). The sleep quality was measured with Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS). Disease severity was assessed with International Cooperative Ataxia Rating Scale (ICARS). All the patients underwent over-night video-polysomnography (VPSG). RESULTS: Out of 36 patients studied, the data of 34 patients [SCA1 (n = 12), SCA2 (n = 13), SCA3 (n = 9)] were used for final analysis. Patients from SCA1, SCA2, and SCA3 category did not show significant differences in age and diseases severity (ICARS). All patients had vertical OKN impairment. Oculomotor impairment was higher in SCA2 patients. Sleep macro architecture analysis showed absent stage R sleep, predominantly in SCA2 (69%) followed by SCA3 (44%) and SCA1 (8%). Patients showed a strong negative correlation of stage R sleep percentage with disease severity and oculomotor dysfunction. CONCLUSION: Voluntary saccadic eye movement velocity and rapid eye movements (REMs) in sleep are strongly correlated. The more severe the saccadic velocity impairment, the less likely was it to generate REMs (rapid eye movements) during stage R. Accordingly 69% of SCA2 patients with severe occulomotor impairments showed absent stage R as per the AASM sleep scoring. We presume that the impaired REMs generation in sleep could be due to oculomotor abnormality and has resulted in spuriously low or absent stage R sleep percentage in SCA patients with conventional VPSG scoring rules. The present study recommends the modification of AASM scoring rules for stage R in patients with oculomotor abnormalities. PMID- 29458754 TI - Processing of DNA Double-Strand Breaks in Yeast. AB - Single-stranded DNA (ssDNA) intermediates are essential for homology-dependent repair of DNA double-strand breaks (DSBs) and for the DNA damage response. Here we describe methods routinely used to identify ssDNA intermediates formed by end processing of site-specific DSBs in Saccharomyces cerevisiae. These methods have been applied in other model systems and human cell lines, and are useful tools to gain insight into the enzymes that process DSBs and how they are regulated. PMID- 29458755 TI - Direct Quantitative Monitoring of Homology-Directed DNA Repair of Damaged Telomeres. AB - Homology-directed DNA repair (HDR) is an evolutionary conserved mechanism that is required for genome integrity and organismal fitness across species. While a myriad of different factors and mechanisms are able to execute HDR, all forms necessitate common steps of DNA damage recognition, homology search and capture, and assembly of a DNA polymerase complex to conduct templated DNA synthesis. The central question of what determines HDR mechanism utilization in mammalian cells has been limited by an inability to directly monitor the DNA damage response and products of repair as they arise from a defined genomic lesion. In this chapter, we describe several methodologies to delineate major steps of HDR during alternative lengthening of telomeres in human cells. This includes procedures to visualize interchromosomal telomere homology searches in real time and quantitatively detect HDR synthesis of nascent telomeres emanating from synchronous activation of telomere DNA double-strand breaks. We highlight the critical details of these methods and their applicability to monitoring HDR at telomeres in a broad variety of mammalian cell types. PMID- 29458756 TI - Kinetic Analysis of the Exonuclease Activity of the Bacteriophage T4 Mre11-Rad50 Complex. AB - Bacteriophage T4 encodes orthologs of the proteins Rad50 (gp46) and Mre11 (gp47), which form a heterotetrameric complex (MR) that is responsible for host genome degradation and the processing of DNA ends for recombination-dependent DNA repair. In this chapter, we describe the ensemble methods currently employed by our laboratory to characterize the exonuclease activity of the T4 MR complex. DNA exonucleases play a vital role in maintaining the integrity of DNA through their participation in DNA repair pathways and as proofreaders for DNA polymerases. Methods for quantifying the general features of the exonuclease, and for determining steady-state kinetic parameters (Km, kcat), the polarity of exonuclease activity, and processivity are presented. These methods should be applicable to all DNA exonucleases, and to some extent endonucleases. PMID- 29458757 TI - Expression, Purification, and Biochemical Evaluation of Human RAD51 Protein. AB - The RAD51 DNA strand exchange protein plays an important role in maintaining the integrity of the human genome. It promotes homology-directed DNA repair by exchanging strands between the damaged and the intact DNA molecules. It also plays an important role in stabilizing distressed DNA replication forks. When overexpressed or misregulated, however, RAD51 contributes to "rogue," genome destabilizing events that can lead to cancer, cell death, and to acquisition of chemotherapy resistance by cancerous cells. Human RAD51 is, therefore, an important and highly coveted anticancer drug target. Biochemical, biophysical, and structural studies of the human RAD51 and establishment of its structure activity relationship require purification of large quantities of protein. In this chapter we describe a robust method for expression and purification of human RAD51 and the methods for assessing its activity based on the single-strand DNA binding stoichiometry and its capacity to carry out the DNA strand exchange reaction. PMID- 29458758 TI - Determining the RAD51-DNA Nucleoprotein Filament Structure and Function by Cryo Electron Microscopy. AB - Homologous recombination is a universal tool for DNA double-strand break and replication fork repair, and it is catalyzed by a highly conserved family of recombinases. In eukaryotes, Rad51 is the recombinase that catalyzes the pairing of homologous DNA molecules and the exchange of strands between the paired molecules. Rad51 assembles on single-stranded DNA (ssDNA) stemming from lesion processing to form a right-handed helical polymer that engages then samples double-stranded DNA (dsDNA) for homology. Upon matching with a homologous sequence, the Rad51-bound ssDNA invades the dsDNA, leading to the formation of a DNA joint with concomitant displacement of the strand of like polarity. The Rad51 DNA filaments are amenable to structural studies using cryo-electron microscopy (cryo-EM). In particular, recent technical breakthroughs in cryo-EM have made it possible to define the structure and function of human RAD51 at near-atomic resolution. In this chapter, we describe our cryo-EM approach to capture the human RAD51 filament structures in various stages of catalysis. The approach may also be useful for related recombinases and other helical assemblies. PMID- 29458760 TI - TIRF-Based Single-Molecule Detection of the RecA Presynaptic Filament Dynamics. AB - RecA is a key protein in homologous DNA repair process. On a single-stranded (ss) DNA, which appears as an intermediate structure at a double-strand break site, RecA forms a kilobase-long presynaptic filament that mediates homology search and strand exchange reaction. RecA requires adenosine triphosphate as a cofactor that confers dynamic features to the filament such as nucleation, end-dependent growth and disassembly, scaffold shift along the ssDNA, and conformational change. Due to the complexity of the dynamics, detailed molecular mechanisms of functioning presynaptic filament have been characterized only recently after the advent of single-molecule techniques that allowed real-time observation of each kinetic process. In this chapter, single-molecule fluorescence resonance energy transfer assays, which revealed detailed molecular pictures of the presynaptic filament dynamics, will be discussed. PMID- 29458759 TI - Observation and Analysis of RAD51 Nucleation Dynamics at Single-Monomer Resolution. AB - Human RAD51 promotes accurate DNA repair by homologous recombination and is involved in protection and repair of damaged DNA replication forks. The active species of RAD51 and related recombinases in all organisms is a nucleoprotein filament assembled on single-stranded DNA (ssDNA). The formation of a nucleoprotein filament competent for the recombination reaction, or for DNA replication support, is a delicate and strictly regulated process, which occurs through filament nucleation followed by filament extension. The rates of these two phases of filament formation define the capacity of RAD51 to compete with the ssDNA-binding protein RPA, as well as the lengths of the resulting filament segments. Single-molecule approaches can provide a wealth of quantitative information on the kinetics of RAD51 nucleoprotein filament assembly, internal dynamics, and disassembly. In this chapter, we describe how to set up a single molecule total internal reflection fluorescence microscopy experiment to monitor the initial steps of RAD51 nucleoprotein filament formation in real-time and at single-monomer resolution. This approach is based on the unique, stretched-ssDNA conformation within the recombinase nucleoprotein filament and follows the efficiency of Forster resonance energy transfer (EFRET) between two DNA conjugated fluorophores. We will discuss the practical aspects of the experimental setup, extraction of the FRET trajectories, and how to analyze and interpret the data to obtain information on RAD51 nucleation kinetics, the mechanism of nucleation, and the oligomeric species involved in filament formation. PMID- 29458761 TI - Methods to Study DNA End Resection I: Recombinant Protein Purification. AB - Accurate repair of DNA double-strand breaks (DSBs) is carried out by homologous recombination. In order to repair DNA breaks by the recombination pathway, the 5' terminated DNA strand at DSB sites must be first nucleolytically processed to produce 3'-overhang. The process is termed DNA end resection and involves the interplay of several nuclease complexes. DNA end resection commits DSB repair to the recombination pathway including a process termed single-strand annealing, as resected DNA ends are generally nonligatable by the competing nonhomologous end joining machinery. Biochemical reconstitution experiments provided invaluable mechanistic insights into the DNA end resection pathways. In this chapter, we describe preparation procedures of key proteins involved in DNA end resection in human cells, including the MRE11-RAD50-NBS1 complex, phosphorylated variant of CtIP, the DNA2 nuclease-helicase with its helicase partners Bloom (BLM) or Werner (WRN), as well as the single-stranded DNA-binding protein replication protein A. The availability of recombinant DNA end resection factors will help to further elucidate resection mechanisms and regulatory processes that may involve novel protein partners and posttranslational modifications. PMID- 29458762 TI - The RadA Recombinase and Paralogs of the Hyperthermophilic Archaeon Sulfolobus solfataricus. AB - Repair of DNA double-strand breaks is a critical function shared by organisms in all three domains of life. The majority of mechanistic understanding of this process has come from characterization of bacterial and eukaryotic proteins, while significantly less is known about analogous activities in the third, archaeal domain. Despite the physical resemblance of archaea to bacteria, archaeal proteins involved in break repair are remarkably similar to those used by eukaryotes. Investigating the function of the archaeal version of these proteins is, in many cases, simpler than working with eukaryotic homologs owing to their robust nature and ease of purification. In this chapter, we describe methods for purification and activity analysis for the RadA recombinase and its paralogs from the hyperthermophilic acidophilic archaeon Sulfolobus solfataricus. PMID- 29458763 TI - Reconstituting the 4-Strand DNA Strand Exchange. AB - Proteins of the Rad51 family play a key role in homologous recombination by carrying out DNA strand exchange. Here, we present the methodology and the protocols for the 4-strand exchange between gapped circular DNA and homologous linear duplex DNA promoted by human Rad51 and Escherichia coli RecA orthologs. This reaction includes formation of joint molecules and their extension by branch migration in a polar manner. The presented methodology may be used for reconstitution of the medial-to-late stages of homologous recombination in vitro as well as for investigation of the mechanisms of branch migration by helicase like proteins, e.g., Rad54, BLM, or RecQ1. PMID- 29458764 TI - Purification of Saccharomyces cerevisiae Homologous Recombination Proteins Dmc1 and Rdh54/Tid1 and a Fluorescent D-Loop Assay. AB - Budding yeast Dmc1 is a member of the RecA family of strand exchange proteins essential for homologous recombination (HR) during meiosis. Dmc1 mediates the steps of homology search and DNA strand exchange reactions that are central to HR. To achieve optimum activity, Dmc1 requires a number of accessory factors. Although methods for purification of Dmc1 and many of its associated factors have been described (Binz, Dickson, Haring, & Wold, 2006; Busygina et al., 2013; Chan, Brown, Qin, Handa, & Bishop, 2014; Chi et al., 2006; Cloud, Chan, Grubb, Budke, & Bishop, 2012; Nimonkar, Amitani, Baskin, & Kowalczykowski, 2007; Van Komen, Macris, Sehorn, & Sung, 2006), Dmc1 has been particularly difficult to purify because of its tendency to aggregate. Here, we provide an alternative and simple high-yield purification method for recombinant Dmc1 that is active and responsive to stimulation by accessory factors. The same method may be used for purification of recombinant Rdh54 (a.k.a. Tid1) and other HR proteins with minor adjustments. We also describe an economical and sensitive D-loop assay for strand exchange proteins that uses fluorescent dye-tagged, rather than radioactive, ssDNA substrates. PMID- 29458765 TI - Probing Dynamic Assembly and Disassembly of Rad51 Tuned by Srs2 Using smFRET. AB - The integrity of DNA is critical for sustaining the life of any living organism, as DNA is a reservoir of its genetic information. However, DNA is continuously damaged by either normal metabolic pathways or environmental insults such as ultraviolet exposure or chemicals. Double-stranded DNA break is one of the most common types of DNA damage that requires activation of homologous recombination (HR) pathway mediated by Rad51 in eukaryotes (Paques & Haber, 1999; Symington, 2002). Rad51 protein forms a helical nucleoprotein filament on resected DNA to initiate homology search but also can interact with other single-stranded DNA (ssDNA)-binding proteins including Srs2. Srs2, a well-known antirecombinase in HR, is an ATP-dependent 3'-5' DNA helicase in the budding yeast Saccharomyces cerevisiae as well as an ssDNA translocase. It disrupts Rad51 filaments, preventing HR (Krejci et al., 2003; Le Breton et al., 2008; Veaute et al., 2003). In the following text, we provide detailed experimental platforms employed to investigate the activity of Rad51 and Srs2 using single-molecule Forster resonance energy transfer and protein-induced fluorescence enhancement. First, we demonstrate how to detect Rad51 filament formation to address the binding site size binding kinetic of the Rad51, as well as the directionality of the filament formation. Next, we explain how to visualize ATP-dependent translocation and unwinding activities of Srs2 on DNA. Lastly, we demonstrate the filament forming activity by Rad51 which is counteracted by the filament removal activity of Srs2. PMID- 29458766 TI - The Recombination Mediator BRCA2: Architectural Plasticity of Recombination Intermediates Revealed by Single-Molecule Imaging (SFM/TIRF). AB - Cellular functions are defined by dynamic assembly, rearrangement, and disassembly of biomolecules to achieve control and specificity. As an example, effective DNA repair is brought about by the concerted action of several DNA processing proteins. Both changes in the structure of individual proteins and in the arrangement of multiple proteins together (referred to here as architecture) are inherent to biological function. These dynamic changes are exemplified in the breast cancer susceptibility protein 2 (BRCA2). BRCA2 is a DNA repair protein that undergoes changes in its own structure and affects changes in molecular architecture with partners during homologous recombination (HR) repair of DNA double strand breaks. These challenging features of BRCA2 protein, its size and predicted stretches of intrinsically disordered regions, have made it difficult to determine the structural consequences and mechanistic importance of interactions between full-length BRCA2 with RAD51 and other HR proteins. In this chapter, we describe scanning force microscopy (SFM)-based approaches to study DNA-protein complexes involved in HR, the architectural plasticity of full-length BRCA2, and the dynamic reorganization of these molecular components associated with essential steps of HR. PMID- 29458767 TI - Single-Molecule Dynamics and Localization of DNA Repair Proteins in Cells. AB - Direct observation of individual protein molecules in their native environment, at nanometer resolution, in a living cell, in motion is not only fascinating but also uniquely informative. Several recent major technological advances in genomic engineering, protein and synthetic fluorophore development, and light microscopy have dramatically increased the accessibility of this approach. This chapter describes the procedures for modifying endogenous genomic loci to producing fluorescently tagged proteins, their high-resolution visualization, and analysis of their dynamics in mammalian cells, using DNA repair proteins BRCA2 and RAD51 as an example. PMID- 29458768 TI - Single-Stranded DNA Curtains for Studying the Srs2 Helicase Using Total Internal Reflection Fluorescence Microscopy. AB - Helicases are crucial participants in many types of DNA repair reactions, including homologous recombination. The properties of these enzymes can be assayed by traditional bulk biochemical analysis; however, these types of assays cannot directly access some types of information. In particular, bulk biochemical assays cannot readily access information that may be obscured in population averages. Single-molecule assays offer the potential advantage of being able to visualize the molecules in question in real time, thus providing direct access to questions relating to translocation velocity, processivity, and insights into how helicases may behave on different types of substrates. Here, we describe the use of single-stranded DNA (ssDNA) curtains as an assay for directly viewing the behavior of the Saccharomyces cerevisiae Srs2 helicase on single molecules of ssDNA. When used with total internal reflection fluorescence microscopy, these methods can be used to track the binding and movements of individual helicase complexes, and allow new insights into helicase behaviors at the single-molecule level. PMID- 29458769 TI - Single-Molecule Analysis of Replication Protein A-DNA Interactions. AB - Replication protein A (RPA) is a highly conserved, eukaryotic ssDNA-binding protein essential for genome stability. RPA interacts with ssDNA and with protein partners to coordinate DNA replication, repair, and recombination. Single molecule analysis of RPA-DNA interactions is leading to a better understanding of the molecular interactions and dynamics responsible for RPA function in cells. Here, we first describe how to express, purify, and label RPA. We then describe how to prepare materials and carry out single-molecule experiments examining RPA DNA interactions using total internal reflection fluorescence microscopy (TIRFM). Finally, the last section describes how to analyze TIRFM data. This chapter will focus on human RPA. However, these methods can be applied to RPA homologs from other species. PMID- 29458770 TI - Single-Molecule Studies of ssDNA-Binding Proteins Exchange. AB - Single-stranded DNA-binding protein (SSB) is important not only for the protection of single-stranded DNA (ssDNA) but also for the recruitment of other proteins for DNA replication, recombination, and repair. The interaction of SSB with ssDNA is highly dynamic as it exists as an intermediate during cellular processes that unwind dsDNA. It has been proposed that SSB redistributes itself among multiple ssDNA segments, but transient intermediates are difficult to observe in bulk experiments. We can use single-molecule FRET microscopy to observe intermediates of the transfer of a single Escherichia coli SSB from one ssDNA strand to another or exchange of one SSB for another on a single ssDNA in real time. This single-molecule approach can be further applicable to understand relative binding affinities and competitive dynamics for other SSBs and variants across various systems. PMID- 29458771 TI - Dissecting the Recombination Mediator Activity of BRCA2 Using Biochemical Methods. AB - Homologous recombination (HR) is an essential pathway to restart stalled replication forks, repair spontaneous DNA double-strand breaks, and generate genetic diversity. Together with genetic studies in model organisms, the development of purification protocols and biochemical assays has allowed investigators to begin to understand how the complex machinery of HR functions. At the core of the HR process is the recombination enzyme RecA in bacteria or RAD51 and DMC1 in eukaryotes. The main steps of HR can be reconstituted in vitro and involve: (1) The formation of a ssDNA-RAD51 complex into a helical structure termed the nucleoprotein filament after one DNA strand has been resected at the site of the break. (2) The homologous DNA pairing with an intact copy of the damaged chromatid to form a joint molecule also called displacement loop (D loop). (3) The exchange of DNA strands and de novo DNA synthesis to restore the damaged/lost DNA. (4) The resolution of joint molecules by nucleolytic cleavage. The human tumor suppressor BRCA2 is a mediator of HR as it actively facilitates the DNA transactions of the recombination proteins RAD51 and DMC1 in a variety of ways: It stabilizes ssDNA-RAD51/DMC1 nucleoprotein filaments. It limits the assembly of RAD51 on dsDNA. It facilitates the replacement of replication protein A by RAD51. The result of these activities is a net increase of DNA strand exchange products as observed in vitro. Here, we describe some of the biochemical assays used to dissect the mediator activities of BRCA2. PMID- 29458772 TI - Approaches to Understanding the Mediator Function of Brh2 in Ustilago maydis. AB - Primary components of the homologous recombination pathway in eukaryotes include Rad51 whose function is to search for DNA sequence homology and promote strand exchange, its mediator BRCA2, and Dss1, a key regulator of BRCA2. We seek to understand the role of BRCA2 in governing the activity of Rad51 and to learn how BRCA2 function is regulated by Dss1. We use the microbe Ustilago maydis as a model system for experimentation because it has a well-conserved BRCA2-homolog, Brh2, and is amenable to biochemical and molecular genetic manipulations and analysis. The powerful attributes of this system open the way for gaining insight into BRCA2's molecular mechanism through avenues not immediately approachable in the vertebrate systems. Here we provide protocols for preparing Brh2, Dss1, and Rad51 as reagents for use in biochemical assays to monitor function and present methods for transposon-based mutational analysis of Brh2 for use in genetic dissection of function. PMID- 29458773 TI - GEN1 Endonuclease: Purification and Nuclease Assays. AB - Successful chromosome segregation depends on the timely removal of DNA recombination and replication intermediates that interlink sister chromatids. These intermediates are acted upon by structure-selective endonucleases that promote incisions close to the junction point. GEN1, a member of the Rad2/XPG endonuclease family, was identified on the basis of its ability to cleave Holliday junction recombination intermediates. Resolution occurs by a nick and counter-nick mechanism in strands that are symmetrically related across the junction point, leading to the formation of ligatable nicked duplex products. The actions of GEN1 are, however, not restricted to HJs, as 5'-flaps and replication fork structures also serve as excellent in vitro substrates for the nuclease. In the cellular context, GEN1 activity is observed late in the cell cycle, as most of the protein is excluded from the nucleus, such that it gains access to DNA intermediates after the breakdown of nuclear envelope. Nuclear exclusion ensures the protection of replication forks and other DNA secondary structures important for normal metabolic processes. In this chapter, we describe the purification of recombinant GEN1 and detail biochemical assays involving the use of synthetic DNA substrates and cruciform-containing plasmids. PMID- 29458774 TI - Biochemical and Structural Properties of Fungal Holliday Junction-Resolving Enzymes. AB - Four-way Holliday junctions in DNA are the central intermediates of genetic recombination and must be processed into regular duplex species. One mechanism for achieving this is called resolution, brought about by structure-selective nucleases. GEN1 is an important junction-resolving enzyme in eukaryotic cells, a member of the FEN1/EXO1 superfamily of nucleases. While human GEN1 is difficult to work with because of aggregation, orthologs from thermophilic fungi have been identified using bioinformatics and have proved to have excellent properties. Here, the expression and purification of this enzyme from Chaetomium thermophilum is described, together with the means of investigating its biochemical properties. The enzyme is quite similar to junction-resolving enzymes from lower organisms, binding to junctions in dimeric form, introducing symmetrical bilateral cleavages, the second of which is accelerated to promote productive resolution. Crystallization of C. thermophilum GEN1 is described, and the structure of a DNA-product complex. Juxtaposition of complexes in the crystal lattice suggests how the structure of a dimeric enzyme with an intact junction is organized. PMID- 29458775 TI - Preparation and Resolution of Holliday Junction DNA Recombination Intermediates. AB - Holliday junctions provide a covalent link between recombining DNA molecules and need to be removed prior to chromosome segregation at mitosis. Defects in their resolution lead to mitotic catastrophe, characterized by the formation of DNA breaks and chromosome aberrations. Enzymes that resolve recombination intermediates have been identified in all forms of life, from bacteriophage, to bacteria, yeast, and humans. In higher eukaryotes, Holliday junctions are resolved by GEN1, a nuclease that is mechanistically similar to the prototypic resolvase Escherichia coli RuvC, and by the SMX trinuclease complex. Studies of these enzymes have been facilitated by the use of plasmid-sized DNA recombination intermediates made by RecA-mediated strand exchange. Here, we detail the preparation of these recombination intermediates, which resemble alpha structures, and their resolution by RuvC and GEN1. PMID- 29458777 TI - Preface. PMID- 29458776 TI - Methods to Study DNA End Resection II: Biochemical Reconstitution Assays. AB - DNA end resection initiates the largely accurate repair of DNA double-strand breaks (DSBs) by homologous recombination. Specifically, recombination requires the formation of 3' overhangs at DSB sites, which is carried out by nucleases that specifically degrade 5'-terminated DNA. In most cases, DNA end resection is a two-step process, comprising of initial short-range followed by more processive long-range resection. In this chapter, we describe selected assays that reconstitute both the short- and long-range pathways. First, we define methods to study the exonuclease and endonuclease activities of the MRE11-RAD50-NBS1 (MRN) complex in conjunction with phosphorylated cofactor CtIP. This reaction is particularly important to initiate processing of DNA breaks and to recruit components belonging to the subsequent long-range pathway. Next, we describe assays that reconstitute the concerted reactions of Bloom (BLM) or Werner (WRN) helicases that function together with the DNA2 nuclease-helicase, and which are as a complex capable to resect DNA of kilobases in length. The reconstituted reactions allow us to understand how the resection pathways function at the molecular level. The assays will be invaluable to define regulatory mechanisms and to identify inhibitory compounds, which may be valuable in cancer therapy. PMID- 29458778 TI - Anti-hypertensive drugs and skin cancer risk: a review of the literature and meta analysis. AB - INTRODUCTION: Several anti-hypertensive drugs have photosensitizing properties, however it remains unclear whether long-term users of these drugs are also at increased risk of skin malignancies. We conducted a literature review and meta analysis on the association between use of anti-hypertensive drugs and the risk of cutaneous melanoma and non-melanoma skin cancer (NMSC). METHODS: We searched PubMed, EMBASE, Google Scholar and the Cochrane Library, and included observational and experimental epidemiological studies published until February 28th, 2017. We calculated summary relative risk (SRR) and 95% confidence intervals (95% CI) through random effect models to estimate the risk of skin malignancies among users of the following classes of anti-hypertensive drugs: thiazide diuretics, angiotensin converting enzyme inhibitors (ACEi), angiotensin receptor blockers (ARB), calcium channel blockers (CCB) and beta-blockers. We conducted sub-group and sensitivity analysis to explore causes of between-studies heterogeneity, and assessed publication bias using a funnel-plot based approach. RESULTS: Nineteen independent studies were included in the meta-analysis. CCB users were at increased skin cancer risk (SRR 1.14, 95% CI 1.07-1.21), and beta blockers users were at increased risk of developing cutaneous melanoma (SRR 1.21, 95% CI 1.05-1.40), with acceptable between-studies heterogeneity (I2 < 50%). There was no association between thiazide diuretics, ACEi or ARB use and skin cancer risk. We found no evidence of publication bias affecting the results. CONCLUSION: Family doctors and clinicians should inform their patients about the increased risk of skin cancer associated with the use of CCB and beta-blockers and instruct them to perform periodic skin self-examination. Further studies are warranted to elucidate the observed associations. PMID- 29458779 TI - Systemic treatment in adult uterine sarcomas. AB - Uterine sarcomas (US) are rare mesenchymal tumours of the uterus and are divided mainly into uterine leiomyosarcoma (uLMS), low grade endometrial stromal sarcoma (LG-ESS), high grade endometrial stromal sarcoma (HG-ESS), adenosarcomas and high grade undifferentiated sarcoma (HGUS). US are often high-grade tumours with a high local recurrence rate and metastatic risk. We here discuss the current standard of care and knowledge of systemic therapy for adult uterine sarcomas, in particular uLMS, LG-ESS, HG-ESS and HGUS, in both the adjuvant as well as the metastatic setting. PMID- 29458780 TI - Immune dysregulation in myelodysplastic syndrome: Clinical features, pathogenesis and therapeutic strategies. AB - Myelodysplastic syndrome (MDS) is a heterogeneous hematological malignancy, characterized by cytopenia and accompanied by a risk of transformation into acute myeloid leukemia (AML). Epidemiological studies for decades have shown association between autoimmune diseases (AIDs) and MDS. Specifically, patients with antecedent AIDs tends to have an increased risk of developing MDS, and these patients display different clinical characteristics and outcomes. Importantly, immune dysregulation has been the common driving force between MDS and AIDs pathogenesis. Both innate and adaptive immune systems are overly active in the hematopoietic niche of MDS. It has been observed that in addition to many cytokines secreted in the bone marrow (BM) microenvironment, almost all types of immune cells and their downstream signaling pathways participate in MDS pathogenesis and evolution. Currently, growth factor therapy and hypomethylating agents (HMAs), along with supportive care, are the mainstay for MDS treatment. As information about the contribution of immune system has started emerging in different subtypes of MDS, we need to highlight the value of immunomodulatory therapies. Immune activation seems to participate specifically in the development of lower-risk MDS, and therefore, use of immunosuppressive therapies would be an ideal treatment option for this type. However, in high-risk MDS, escape from immune surveillance appears to contribute to its progression, and thus, several immune-activating treatment options, including immune checkpoint inhibitors and vaccines, are being considered. HMAs have been approved for use in treating high risk MDS for many years based on their cytotoxicity, but since they also display an epigenetic-immunomodulatory role, they can be an option for lower-risk MDS. Thus, in this review, we discuss the immune dysregulation in MDS, including its clinical features, pathogenic mechanism and immunomodulatory therapeutic options.

The risk is highest in the most developed world but also is markedly rising in the developing countries. It is well documented that melatonin has a significant anti tumor activities demonstrated on various cancer types in a plethora of preclinical studies. In breast cancer, melatonin is capable to disrupt estrogen dependent cell signaling, resulting in a reduction of estrogen-stimulated cells, moreover, it's obvious neuro-immunomodulatory effect in organism was described. Several prospective studies have demonstrated the inverse correlation between melatonin metabolites and the risk of breast cancer. This correlation was confirmed by observational studies that found lower melatonin levels in breast cancer patients. Moreover, clinical studies have showed that circadian disruption of melatonin synthesis, specifically night shift work, is linked to increased breast cancer risk. In this regard, proper light/dark exposure with more selective use of light at night along with oral supplementation of melatonin may have benefits for high-risk women. The results of current preclinical studies, the mechanism of action, and clinical efficacy of melatonin in breast cancer are reviewed in this paper. Melatonin alone or in combined administration seems to be appropriate drug for the treatment of early stages of breast cancer with documented low toxicity over a wide range of doses. These and other issues are also discussed. PMID- 29458782 TI - Loco-regional treatment for castration-resistant prostate cancer: Is there any rationale? A critical review from the AFU-GETUG. AB - Emerging evidence from population-based and retrospective series suggests a potential improvement of clinical outcomes in metastatic prostate cancer. Moreover, metastasis-directed treatment has shown encouraging results in this setting. There is an increasing interest in exploring the potential of local therapies in advanced prostate cancer, but this has rarely been specifically addressed in the castration-resistant state, whether non-metastatic or metastatic. A review of relevant articles was performed on the oncologic benefit of local treatment of the primary tumor or metastasis-targeted treatment in castration-resistant prostate cancer patients. The main goal of this strategy is to delay introduction of a new systemic agent to maintain quality of life and potentially to limit resistance. Further investigation is required to provide high-level evidence for the oncologic benefit of this treatment modality. PMID- 29458783 TI - Precision medicine in ALK rearranged NSCLC: A rapidly evolving scenario. AB - IMPORTANCE: The identification of anaplastic lymphoma kinase (ALK) rearrangements in 2-5% of non-small cell lung cancer (NSCLC) patients led to the rapid clinical development of its oral tyrosine kinase inhibitor (TKI). Crizotinib was the first ALK inhibitor approved and utilised in the treatment of ALK+ NSCLC patients in the second line setting first and subsequently in the first line one. Since then many other ALK inhibitors have been developed (ceritinib, alectinib, brigatinib, lorlatinib,etc) and the treatment paradigm of these patients has considerably drifted. The questions regarding their treatment at progression remains unanswered at the moment. OBJECTIVE: Our review clarifies what it is the state of the art in the treatment of ALK rearranged NSCLC patients, highlights the mechanisms of primary and secondary resistance mutations and suggests a treatment algorithm based on specific primary resistance or acquired mutations. EVIDENCE REVIEW: Studies that enrolled ALK+ NSCLC patients with locally advance or metastatic disease receiving treatment with ALK inhibitor, first or second line, were identified using electronic databases (MEDLINE, EMBASE, and Cochrane library). Trials were excluded if they were phase 1, enrolled less than 10 patients. FINDING: Overall 1942 patients were included in our review. It confirms the role and the efficacy in first line of Alectinib but it highlights also that all the ALK inhibitors could play a crucial role during the patients' journey. Identifying the different mutations and utilising the most active ALK inhibitor depending on the "up-to-date" driven mutation is the way forward in the management of those patients. CONCLUSIONS AND RELEVANCE: the review shows the rapid drifting in the management of ALK+ NSCLC patients and the importance of fully understanding and acknowledging the role of the resistance mutation, primary or acquired. We strongly advocate a comprehensive genomic approach in the management of ALK+ NSCLC patients who develop resistance mutations that are still targetable by a different ALK inhibitor. PMID- 29458784 TI - Review: Effectiveness of implementation strategies to increase physical activity uptake during and after cancer treatment. AB - BACKGROUND: The purpose of this review was to assess the effectiveness of different strategies to implement physical activity during and after cancer treatment. DESIGN: We searched for studies containing strategies to implement physical activity in cancer care that meet the inclusion criteria of the Cochrane EPOC group. The primary outcome was physical activity uptake. We expressed the effectiveness of the strategies as the percentage of studies with improvement. RESULTS: Nine studies met the inclusion criteria. Patient groups doing physical activities via an implementation strategy had better outcomes than those receiving usual care: 83% of the studies showed improvement. Strategies showing significant improvement compared to usual care employed healthcare professionals to provide individual counselling or advice for exercise or interactive elements such as audit and feedback systems. When comparing the different strategies 1) interactive elements or 2) elements tailored to the needs of the patients had better physical activity uptake. CONCLUSIONS: Implementation strategies containing individual and interactive elements, tailored to the individual needs of patients, are more successful in improving physical activity uptake.

PMID- 29458787 TI - A systematic review of the safety profile of the different combinations of fluoropyrimidines and oxaliplatin in the treatment of colorectal cancer patients. AB - The available fluoropyrimidines and oxaliplatin combinations for colorectal cancer patients have different safety profiles. The aim of this systematic review was to compare their toxicities. The eligible studies were classified as: no bolus; 5-FU single bolus; 5-FU double bolus; capecitabine. We calculated the incidence of "any-grade" and "severe" toxicity for haematological and non haematological adverse events of each group. We identified 184 treatment groups; compared to 5-FU double bolus, except for high-grade anaemia, all the groups showed reduced risk of haematological toxicities, with the most relevant advantages for single bolus regimens. Concerning non-haematological toxicities, compared to double bolus, the single bolus group showed a statistically significant reduced risk for many gastrointestinal toxicities and for pheripheral neuropathy. This is the first systematic review of the toxicity profile of different 5-FU or capecitabine and oxaliplatin regimens. Single 5-FU bolus is associated with a definitely favourable toxicity profile, both for haematological and non-haematological toxicity. PMID- 29458788 TI - Protective effects of curcumin against doxorubicin-induced toxicity and resistance: A review. AB - Doxorubicin (DOX)-induced toxicity and resistance are major obstacles in chemotherapeutic approaches. Despite effective in the treatment of numerous malignancies, some clinicians have voiced concern that DOX has the potential to cause debilitating consequences in organ tissues, especially the heart. The mechanisms of toxicity and resistance are respectively related to induction of reactive oxygen species (ROS) and up-regulation of ATP-binding cassette (ABC) transporter. Curcumin (CUR) with several biological and pharmacological properties is expected to restore DOX-mediated impairments to tissues. This review is intended to address the current knowledge on DOX adverse effects and CUR protective actions in the heart, kidneys, liver, brain, and reproductive organs. Coadministration of CUR and DOX is capable of ameliorating DOX toxicity pertained to antioxidant, apoptosis, autophagy, and mitochondrial permeability. PMID- 29458789 TI - Physical activity reduces fatigue in patients with cancer and hematopoietic stem cell transplant recipients: A systematic review and meta-analysis of randomized trials. AB - PURPOSE: Objective was to determine whether physical activity reduces the severity of fatigue in patients with cancer or hematopoietic stem cell transplant (HSCT) recipients. METHODS: We conducted a meta-analysis of randomized trials comparing physical activity with control interventions for the management of fatigue in patients with cancer or HSCT recipients. RESULTS: There were 170 trials included. Physical activity reduced the severity of fatigue when compared to all control groups (standardized mean difference -0.49, 95% confidence interval -0.60 to -0.37; P < 0.00001). Aerobic, neuromotor, resistance and combination exercises were all effective in reducing fatigue although smaller effects were observed with resistance exercises (P interaction = 0.01). Other intervention and patient characteristics did not influence the effect of physical activity on the severity of fatigue. CONCLUSIONS: Physical activity was effective at reducing fatigue in patients with cancer and HSCT recipients across patient sub-groups. Determining the best approaches for safe implementation should be a priority. PMID- 29458790 TI - Non pharmacological interventions and non-fentanyl pharmacological treatments for breakthrough cancer pain: A systematic and critical review. AB - BACKGROUND: Oral opioids or other pharmacological or non-pharmacological interventions are often suggested in the management of breakthrough cancer pain (BTcP). The aim of this systematic and critical review was to analyse and critically comment the evidence of any non-fentanyl therapies proposed for BTcP. METHODS: A systematic literature search was carried out to find studies providing clinical data on any treatment excluding fentanyl products. RESULTS: No data exist about the use of oral opioids. Some information is available on parenteral morphine in a large sample of patients and episodes of BTcP. For other treatments, including methadone, nitrous oxide, anti-inflammatory drugs, samarium, and gabapentin the existing data, observational and obtained in a small number of patients do not provide useful information to be generalized. Only ketamine, a drug difficult to use for many physicians, particularly in determined setting, provided some evidence according a randomized controlled double-blind study. CONCLUSIONS: Recommendations suggesting the use of oral opioids or other pharmacological and non-pharmacologic interventions for BTcP, are not based on any, even minimal evidence. These treatments are worthwhile of further investigation, particularly in determined conditions that should fit the pharmacokinetics of oral opioids. PMID- 29458791 TI - The ethical plausibility of the 'Right To Try' laws. AB - 'Right To Try' (RTT) laws originated in the USA to allow terminally ill patients to request access to early stage experimental medical products directly from the producer, removing the oversight and approval of the Food and Drug Administration. These laws have received significant media attention and almost equally unanimous criticism by the bioethics, clinical and scientific communities. They touch indeed on complex issues such as the conflict between individual and public interest, and the public understanding of medical research and its regulation. The increased awareness around RTT laws means that healthcare providers directly involved in the management of patients with life-threatening conditions such as cancer, infective, or neurologic conditions will deal more frequently with patients' requests of access to experimental medical products. This paper aims to assess the ethical plausibility of the RTT laws, and to suggest some possible ethical tools and considerations to address the main issues they touch. PMID- 29458792 TI - Circulating tumour DNA, a promising biomarker for the management of colorectal cancer. AB - Circulating cell free tumour DNA (ctDNA) maintains the same genomic alterations that are present in the corresponding tumour, thereby allowing for quantitative and qualitative real-time evaluation in body fluids as an alternative to onerous repeat biopsies. Improvements in the sensitivity of techniques used to identify ctDNA has led to a surge of research investigating its role in the detection of: early disease, relapse, response to therapy and emerging drug resistance mechanisms. Following curative surgery, ctDNA detection is a promising marker of minimal residual disease and could better select patients for adjuvant chemotherapy. Longitudinal monitoring could help identify early relapse. In metastatic disease, ctDNA can predict response to chemotherapy prior to evidence of disease progression on imaging and investigate novel primary and acquired resistance mechanisms to targeted therapies. More experience in detecting, analysing and interpreting ctDNA within prospective trials, will better define its role for implementation into routine clinical practice. PMID- 29458793 TI - An attempt to conceptualize the individual onco-functional balance: Why a standardized treatment is an illusion for diffuse low-grade glioma patients. AB - In the era of evidence-based medicine, clinicians aim to establish standards of care from randomized studies. Following, personalized medicine has emerged, as new individualized biomarkers could help to predict sensitivity to specific treatment. In this paper, we show that, for diffuse low-grade glioma, some specificities - dual goal of both survival and functional gain, long duration of the disease with multistep treatments, multiparametric evaluation of the onco functional balance of each treatment modality - call for a change of paradigm. After summarizing how to weight the benefits and risks of surgery, chemotherapy and radiotherapy, we show that the overall efficacy of a treatment modality cannot be assessed per se, as it depends on its integration in the whole sequence. Then, we revisit the notion of personalized medicine: instead of decision-making based solely on molecular profile, we plead for a recursive algorithm, allowing a dynamic evaluation of the onco-functional balance, integrating many individual characteristics of the patient's tumor and brain function.

The role of emerging therapeutic vaccines is reviewed. PMID- 29458795 TI - Mucins: Structural diversity, biosynthesis, its role in pathogenesis and as possible therapeutic targets. AB - Mucins are the main structural components of mucus that create a selective protective barrier for epithelial surface and also execute wide range of other physiological functions. Mucins can be classified into two types, namely secreted mucins and membrane bounded mucins. Alterations in mucin expression or glycosylation and mislocalization have been seen in various types of pathological conditions such as cancers, inflammatory bowel disease and ocular disease, which highlight the importance of mucin in maintaining homeostasis. Hence mucins can be used as attractive target for therapeutic intervention. In this review, we discuss in detail about the structural diversity of mucins; their biosynthesis; its role in pathogenesis; regulation and as possible therapeutic targets.

AB - The occurrence of mutations of TDP-43, FUS, and C9ORF72 in amyotrophic lateral sclerosis (ALS) suggests pathogenic alterations to RNA metabolism and specifically to microRNA (miRNA) biology. Moreover, several ALS-related proteins impact stress granule dynamics affecting miRNA biogenesis and cellular miRNA levels. miRNAs are present in different biological fluids and have been proposed as potential biomarkers. Here we used next-generation sequencing to perform a comparative analysis of the expression profile of circulating miRNAs in the serum of 2 mutant superoxide dismutase 1 transgenic mice. Top hit candidates were then validated using quantitative real-time polymerase chain reaction, confirming significant changes for 6 miRNAs. In addition, one of these miRNAs was also altered in mutant TDP-43 mice. Then, we tested this set of miRNAs in the serum from sporadic ALS patients, observing a significant deregulation of hsa-miR-142 3p and hsa-miR-1249-3p. A negative correlation between the revised ALS functional rating scale and hsa-miR-142-3p levels was found. Bioinformatics analysis of the regulatory network governed by hsa-miR-142-3p identified TDP-43 and C9orf72 as possible targets, suggesting a connection with ALS pathogenesis. This study identifies miRNAs that are altered in ALS that may serve as potentials biomarkers. PMID- 29458841 TI - Early-life stress induces cognitive disorder in middle-aged mice. AB - Early-life stress can induce several neuropsychological disorders in adulthood. However, the underlying mechanisms inducing such disorders are still not fully understood. Furthermore, the effects of early-life stress on the changes in cognitive function with age are still not clarified. In this study, we used maternal deprivation (MD) to examine the cognitive function in middle-aged mice using a touchscreen-equipped operant chamber. In the visual-discrimination task, the aged (~1.4 years old) control mice could accurately learn to discriminate between different visual stimuli. In contrast, the correct response rate of aged MD mice increased to ~60% by day 10; it was still significantly lower than that of the control mice (85%). In the hippocampus of aged MD mice, the expression level of the N-methyl-d-aspartate receptor subunit GluN1 decreased significantly as compared to that in control mice. On the other hand, no significant difference in GluN1 expression level was detected in young (2.5 months old) mice. These findings indicate that early-life stress accelerates cognitive impairment in middle-aged mice. PMID- 29458843 TI - A critical role for very long-chain fatty acid elongases in oleic acid-mediated Saccharomyces cerevisiae cytotoxicity. AB - Elongases FEN1/ELO2 and SUR4/ELO3 are important enzymes involved in the elongation of long-chain fatty acids (LCFAs) to very long-chain fatty acids (VLCFAs) in Saccharomyces cerevisiae. The molecular mechanism of the involvement of these elongases in lipotoxicity is unclear. In the present study, we investigated the role of VLCFA elongases in oleic acid-mediated yeast cytotoxicity. The spot test showed that yeast strains with the deletion of ELO2 or ELO3 were strikingly sensitive to oleic acid, while there was no change on the growth of strain with deleted ELO1 which was involved in the elongation of C14 fatty acid (FA) to C16 FA. By using GC-MS, the unsaturation index was increased in elo2? and elo3? mutants after treatment with oleic acid (OLA). However, the proportion of VLCFAs was increased in response to OLA in the wild-type strain. The growth inhibition of elo2? and elo3? could be partially rescued by two commonly used antioxidant agents N-acetyl cysteine (NAC) and Ascorbic acid (VC). The further study showed that exposure to excess OLA led to an increase in the levels of reactive oxygen species (ROS) and thiobarbituric acid reactive substances (TBARS), and a decline in the quantity of reduced glutathione (GSH) in both the wild type and mutant strains. However, the antioxidant enzyme activities of superoxide dismutase (SOD) and catalase (CAT) were increased in the wild type and elo1? strains, while they were significantly decreased in the mutants of elo2? and elo3? after treated with excess OLA. Thus, oxidative damage mainly contributed to the cell death induced by OLA in ole2? and ole3?. Taken together, although disruption of ELO2 or ELO3 did not affect the cellular lipid unsaturation, they altered the distribution and propotion of cellular VLCFAs, leading to the cell membrane impairment, which augmented the ability of OLA to permeabilize the plasma membrane. The data suggest that the very long-chain fatty acids elongases ELO2 and ELO3 play important roles in lipotoxic cell death induced by OLA through maintaining a balanced FA composition in plasma membrane. PMID- 29458842 TI - Cognitive response to fish oil, blueberry, and combined supplementation in older adults with subjective cognitive impairment. AB - Given evidence that eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and anthocyanin-rich blueberries provide neurocognitive benefit, we investigated long term supplementation in older adults with cognitive complaints. In a 24-week randomized, double-blind, placebo-controlled trial, elderly men and women received daily fish oil (FO) or blueberry (BB) or both. Diet records confirmed that participants reduced background consumption of EPA, DHA, and anthocyanins as prescribed. Erythrocyte EPA + DHA composition increased in the FO groups (p = 0.0001). Total urinary anthocyanins did not differ between the groups after supplementation but glycoside and native (food) forms increased only in the BB supplemented groups. The FO (p = 0.03) and BB (p = 0.05) groups reported fewer cognitive symptoms, and the BB group showed improved memory discrimination (p = 0.04), indicating that supplementation improved cognition. Cognitive benefit in the BB group was associated with the presence of urinary anthocyanins reflecting recent BB intake but not with anthocyanin metabolites. However, combined FO + BB treatment was not associated with cognitive enhancement as expected. PMID- 29458844 TI - Modulation in phenolic root exudate profile of Abelmoschus esculentus expressing activation of defense pathway. AB - Phenolics play a key role in communication between plants and microbes in the rhizosphere. In this study, shikimic, gallic, fumaric, ferulic, vanillic acid and quercetin in root exudates of Abelmoschus esculentus act as chemoattractants of endophytic Alcaligenes faecalis strains, BHU 12, BHU 16 and BHU M7. In vitro chemotaxis assay showed that BHU 12 expressed highest chemotactic movement (CFU ~50*1012) towards A.esculentus root exudates followed by BHU 16 and BHU M7 (CFU~ 9*1012), thereby confirming their ability to colonize the host rhizoplane region. However, BHU 16 expressed highest biofilm formation ability followed by BHU 12 and BHU M7. Assessment of chemotactic and biofilm formation potential towards individual phenolic acids revealed BHU 12 to be maximally attracted towards 1MUM shikimic acid (2*1015) while BHU 16 towards 1mM vanillic acid (6.5*1012) and BHU M7 towards 1mM ferulic acid (3.5*1012), thereby confirming the phenolic acid components responsible for particularly attracting the endophytic isolates. Upon colonization, the endophytic isolates modified the phenolic profiles of root exudates in planta in a manner so as to plausibly attract more of the beneficial rhizospheric microbiota as well as self-fortification against pathogenic microbes. This hypothesis was verified by monitoring the changes in phenolic components of A. esculentus root exudate owing to S. rolfsii infection, a disastrous soil-borne pathogen. Thus, on the whole, the work provides intricate details of plant-endophyte interactions for biotic stress management through careful manipulation of root exudates, thereby aiding in sustainable agriculture. PMID- 29458845 TI - Leptospirosis in human: Biomarkers in host immune responses. AB - Leptospirosis remains one of the most widespread zoonotic diseases caused by spirochetes of the genus Leptospira, which accounts for high morbidity and mortality globally. Leptospiral infections are often found in tropical and subtropical regions, with people exposed to contaminated environments or animal reservoirs are at high risk of getting the infection. Leptospirosis has a wide range of clinical manifestations with non-specific signs and symptoms and often misdiagnosed with other acute febrile illnesses at early stage of infection. Despite being one of the leading causes of zoonotic morbidity worldwide, there is still a gap between pathogenesis and human immune responses during leptospiral infection. It still remains obscure whether the severity of the infection is caused by the pathogenic properties of the Leptospira itself, or it is a consequence of imbalance host immune factors. Hence, in this review, we seek to summarize the past and present milestone findings on the biomarkers of host immune response aspects during human leptospiral infection, including cytokine and other immune mediators. A profound understanding of the interlink between virulence factors and host immune responses during human leptospirosis is imperative to identify potential biomarkers for diagnostic and prognostic applications as well as designing novel immunotherapeutic strategies in future. PMID- 29458847 TI - The special existences: nanoRNA and nanoRNase. AB - To adapt to a wide range of nutritional and environmental changes, cells must adjust their gene expression profiles. This process is completed by the frequent transcription and rapid degradation of mRNA. mRNA decay is initiated by a series of endo- and exoribonucleases. These enzymes leave behind 2- to 5-nt-long oligoribonucleotides termed "nanoRNAs" that are degraded by specific nanoRNases; the degradation of nanoRNA is essential because nanoRNA can mediate the priming of transcription initiation that is harmful for the cell via an unknown mechanism. Identified nanoRNases include Orn in E. coli, NrnA and NrnB in B. subtilis, and NrnC in Bartonella. Even though these nanoRNases can degrade nanoRNA specifically into mononucleotides, the biochemical features, structural features and functional mechanisms of these enzymes are different. Sequence analysis has identified homologs of these nanoRNases in different bacteria, including Gammaproteobacteria, Betaproteobacteria, Alphaproteobacteria, Firmicutes and Cyanobacteria. However, there are several bacteria, such as those belonging to the class Thermolithobacteria, that do not have homologs of these nanoRNases. In this paper, the source of nanoRNA, the features of different kinds of nanoRNases and the distribution of these enzymes in prokaryotes are described in detail. PMID- 29458846 TI - Desert actinobacteria as a source of bioactive compounds production with a special emphases on Pyridine-2,5-diacetamide a new pyridine alkaloid produced by Streptomyces sp. DA3-7. AB - In the present study, 134 morphologically distinct actinobacteria isolates were obtained from soil samples from 10 different localities in the Saudi Arabian desert. The preliminary screening revealed that 16 of these isolates possessed antimicrobial activity. One isolate, which was identified as Streptomyces sp. DA3 7, possessed broad-spectrum antimicrobial activity against both gram-positive and gram-negative bacteria, as well as against fungi, and modified nutrient glucose medium was suitable for Streptomyces sp. DA3-7 to produce extracellular metabolites. The ethyl acetate extract of Streptomyces sp. DA3-7 exhibited antimicrobial activity against Enterococcus faecalis and Salmonella typhimurium, with minimum inhibitory concentrations of 78 and 156MUg/mL, respectively, as well as strong cytotoxicity (24h IC50 85MUg/mL) against MCF-7 human breast adenocarcinoma cells. The active compound was separated, purified, and identified as Pyridine-2,5-diacetamide (C9H11N3O2+H+, 194.21), which possessed a lowest minimum inhibitory concentration (31.25MUg/mL) against both Escherichia coli and Cryptococcus neoformans. The antimicrobial activities of this novel compound are reported here for the first time.

AB - Biological control is an eco-friendly strategy for mitigating and controlling plant diseases with negligible effects on human health and environment. Biocontrol agents are mostly isolated from field crops, and microbiomes associated with wild native plants is underexplored. The main objective of this study was to characterize the bacterial isolates associated with Smilax bona-nox L, a successful wild plant with invasive growth habits. Forty morphologically distinct bacterial isolates were recovered from S. bona-nox. Based on 16S rRNA gene sequencing, these isolates belonged to 12 different genera namely Burkholderia, Pseudomonas, Xenophilus, Stenotrophomonas, Pantoea, Enterobactriaceae, Kosakonia, Microbacterium, Curtobacterium, Caulobacter, Lysinibacillus and Bacillus. Among them, Pseudomonas sp. EA6 and Pseudomonas sp. EA14 displayed the highest potential for inhibition of Phytophthora. Based on sequence analysis of rpoD gene, these isolates revealed a 97% identity with a Pseudomonas fluorescence strain. Bioactivity-driven assays for finding bioactive compounds revealed that crude proteins of Pseudomonas sp. EA6 inhibited mycelial growth of P. parasitica, whereas crude proteins of Pseudomonas sp. EA14 displayed negligible activity. Fractionation and enzymatic analyses revealed that the bioactivity of Pseudomonas sp. EA6 was mostly due to glucanolytic enzymes. Comparison of chromatographic profile and bioactivity assays indicated that the secreted glucanolytic enzymes consisted of beta-1,3 and beta-1,4 glucanases, which acted together in hydrolyzing Phytophthora cell walls. Since the biological activity of the crude glucanolytic extract was >60-fold higher than the purified beta-1,3 glucanase, the glucanolytic enzyme system of Pseudomonas sp. EA6 likely acts synergistically in cell wall hydrolysis of P. parasitica. PMID- 29458850 TI - For the greater good: Programmed cell death in bacterial communities. AB - For a long a time programmed cell death was thought to be a unique characteristic of higher eukaryotes, but evidence has accumulated showing that programmed cell death is a universal phenomenon in all life forms. Many different types of bacterial programmed cell death systems have been identified, rivalling the eukaryotic systems in diversity. Bacteria are singular, seemingly independently living organisms, however they are part of complex communities. Being part of a community seems indispensable for survival in different environments. This review is focussed on the mechanism of and reasons for bacterial programmed cell death in the context of bacterial communities.

AB - An entomopathogenic fungus, Lecanicillium psalliotae strain IISR-EPF-02 previously found infectious to cardamom thrips, Sciothrips cardamomi promoted plant growth in cardamom, Elettaria cardamomum. The isolate exhibited direct plant growth promoting traits by production of indole-3-acetic acid and ammonia and by solubilizing inorganic phosphate and zinc. It also showed indirect plant growth promoting traits by producing siderophores and cell wall-degrading enzymes like, alpha-amylases, cellulases and proteases. In pot culture experiments, application of the fungus at the root zone of cardamom seedlings significantly increased shoot and root length, shoot and root biomass, number of secondary roots and leaves and leaf chlorophyll content compared to untreated plants. This is the first report on the plant growth promoting traits of this fungus. The entomopathogenic and multifarious growth promoting traits of L. psalliotae strain IISR-EPF-02 suggest that it has great potential for exploitation in sustainable agriculture.

AB - Salmonellae is one of the most important foodborne pathogens and becomes resistant to multiple antibiotics, which represents a significant challenge to food industry and public health. However, a molecular signature that can be used to distinguish antimicrobial resistance profile, particularly multi-drug resistance or extensive-drug resistance (XDR). In the current study, 168 isolates from the chicken and pork production chains and ill chickens were characterized by serotyping, antimicrobial susceptibility test, multilocus sequence typing (MLST) and pulsed-field gel electrophoresis (PFGE). The results showed that these isolates belonged to 13 serotypes, 14 multilocus sequence types (STs), 94 PFGE genotypes, and 70 antimicrobial resistant profiles. S. Enteritidis, S. Indiana, and S. Derby were the predominant serotypes, corresponding to the ST11, ST17, and ST40 clones, respectively and the PFGE Cluster A, Cluster E, and Cluster D, respectively. Among the ST11-S. Enteritidis (Cluster A) and the ST40-S. Derby (Cluster D) clones, the majority of isolates were resistant to 4-8 antimicrobial agents, whereas in the ST17S. Indiana (Cluster E) clone, isolates showed extensive-drug resistance (XDR) to 9-16 antimicrobial agents. The blaTEM-1-like gene was prevalent in the ST11 and ST17 clones corresponding to high ampicillin resistance. The blaTEM-1-like, blaCTX-M, blaOXA-1-like, sul1, aaC4, aac(6')-1b, dfrA17, and floR gene complex was highly prevalent among isolates of ST17, corresponding to an XDR phenotype. These results demonstrated the association of the resistant phenotypes and genotypes with ST clone and PFGE cluster. Our results also indicated that the newly identified gene complex comprising blaTEM-1 like, blaCTX-M, blaOXA-1-like, sul1, aaC4, aac(6')-1b, dfrA17, and floR, was responsible for the emergence of the ST17S. Indiana XDR clone. ST17 could be potentially used as a molecular signature to distinguish S. Indiana XDR clone.

AB - Spermidine (Spd), spermine (Spm), and putrescine (Put), which are the most widely distributed cellular polyamines, are essential for normal growth and multiplication of both eukaryotic and prokaryotic cells. In this study, we identified the only putative polyamine transport system PotABCD in Streptococcus suis, a worldwide zoonotic Gram-positive pathogen causing lethal infections in humans and pigs. It was discovered that S. suis could uptake polyamines preferably Spd and Spm. By constructing a potA deleted mutant, we confirmed that PotABCD was responsible for polyamine uptake, and PotD bound to the protein of polyamines. The four PotABCD genes were co-transcribed with murB, a gene involved in peptidoglycan (PG) synthesis. Furthermore the roles of polyamine transport system in maintaining the PG structure were detected to understand the biological significance of this co-transcription. In contrast to the wild type, the mutant DeltapotA exhibited elongated chain length and abnormal cell division morphology. Phenotypic changes were attributed to be the up-regulation of genes involved in PG synthesis and hydrolysis in DeltapotA. Additionally, polyamines functioned not only as feedback regulators of PotA by inhibiting PotA activity but also as regulators on potABCD and genes involved in PG synthesis. This study reveals the functions of PotABCD in polyamine transport and the regulatory roles of polyamines in PG synthesis. Results provide new insights into the machineries contributing to normal growth and cell division of S. suis. PMID- 29458853 TI - Fusarium species as pathogen on orchids. AB - The recent surge in demand for exotic ornamental crops such as orchids has led to a rise in international production, and a sharp increase in the number of plant and plant products moving between countries. Along with the plants, diseases are also being transported and introduced into new areas. Fusarium is one of the major diseases causing pathogens infecting orchids that is spreading through international trade. Studies have identified several species of Fusarium associated with orchids, some are pathogenic and cause symptoms such as leaf and flower spots, leaf or sheath blights, pseudostem or root rots, and wilts. Infection and damage caused by Fusarium reduces the quality of plants and flowers, and can cause severe economic losses. This review documents the current status of the Fusarium-orchid interaction, and illustrates challenges and future perspectives based on the available literature. This review is the first of Fusarium and orchid interactions, and integrates diverse results that both furthers the understanding and knowledge of this disease complex, and will enable the development of effective disease management practices. PMID- 29458854 TI - 5-hydroxymethyl-2-furaldehyde from marine bacterium Bacillus subtilis inhibits biofilm and virulence of Candida albicans. AB - Candida albicans is considered as the primary etiologic agent of candidiasis, a very common fungal infection in human. The yeast to hyphal transition and ability to form hypoxic biofilm on medical devices is well allied with virulence and antifungal resistance of C. albicans. Antagonistic agents that inhibit biofilm formation and alter susceptibility of C. albicans to conventional antifungals is of profound need. The present study explores the antibiofilm efficacy of Bacillus subtilis, a marine bacterial isolate from Palk Bay against C. albicans. Mass spectrometric analysis of ethyl acetate extract of B. subtilis unveiled 5 hydroxymethyl-2-furaldehyde (5HM2F) as one of its major components. 5HM2F demonstrated concentration dependent biofilm inhibition, which was also corroborated through microscopic analysis. Furthermore, 5HM2F was effective in inhibiting other virulence factors of C. albicans such as morphological transition and secreted hydrolases production. Fourier transform infrared spectroscopic analysis showed alteration in amide bond region. The reduction in ergosterol content and increased antifungal susceptibility was well allied with real time PCR result, which showed down regulation of genes involved in drug resistance mechanisms. In vivo study using Caenorhabditis elegans also substantiated the antivirulence efficacy of 5HM2F at in vivo condition. Thus, the present study reports the therapeutic potential of 5HM2F against C. albicans infections. PMID- 29458855 TI - Streptomyces puniceus strain AS13., Production, characterization and evaluation of bioactive metabolites: A new face of dinactin as an antitumor antibiotic. AB - A highly active actinobacterial strain isolated from untapped areas of Northwestern Himalayas and characterised as Streptomyces puniceus strain AS13 by 16S rRNA gene sequencing was selected for production of bioactive metabolites. The bioassay-guided fractionation of microbial cultured ethyl acetate extract of the strain, led to isolation of macrotetrolide compound 1 (Dinactin) and compound 2 (1-(2,4-dihydroxy-6-methylphenyl)-ethanone). Structures of the isolated compounds were elucidated interpretation of NMR and other spectroscopic data including HR-ESI-MS, FT-IR. These compounds are reported for first time from Streptomyces Puniceus. Compound 1 exhibited strong anti-microbial activity against all tested bacterial pathogens including Mycobacterium tuberculosis. The MIC values of compound 1 against Gram negative and Gram positive bacterial pathogens ranged between 0.019 - 0.156MUgml-1 and 1MUgml-1 against Mycobacterium tuberculosis H37Rv. Dinactin exhibited marked anti-tumor potential with IC50 of 1.1- 9.7MUM in various human cancerous cell lines and showed least cytotoxicity (IC50~80MUM) in normal cells (HEK-293). Dinactin inhabited cellular proliferation in cancer cells, reduced their clonogenic survival as validated by clonogenic assay and also inhabited cell migration and invasion characteristics in colon cancer (HCT-116) cells. Our results expressed the antimicrobial potential of dinactin and also spotted its prospective as an antitumor antibiotic. PMID- 29458856 TI - Evaluation of fungal community involved in the bioderioration process of wooden artworks and canvases in Montefeltro area (Marche, Italy). AB - Microbiological monitoring represents one of the most useful methods to assess potential risks related to the integrity of cultural heritage. The objective of this work was to evaluate the fungal community prevalent in 64 different artworks of Montefeltro area (Marche, central Italy). A total of 293 swabs were collected and, among these, 2.3% resulted negative to cultural method, while 87.7% were positive for the presence of filamentous fungi, yeasts and Actinomycetes. Totally, 11 genera and 12 different species were recovered from Sabouraud Dextrose Agar (SDA), Czapek Dox Agar (CDA), Malt Extract Agar (MEA), including 73 strains of Mycelia sterilia. Penicillium spp. was isolated mostly from canvases (28.8%), while Aspergillus spp. was most present in wooden artworks (25.3%). SDA was the best performing medium with 57.1% of isolations, followed by CDA and MEA with percentages of 24.8 and 18.1% respectively. This study could be useful to better understand the microorganism-related phenomena in cultural heritage of Marche region, identifying the potential risks and defining preventive protecting such as climate control, frequent cleaning and environmental monitoring. PMID- 29458857 TI - Revealing the inhibitory potential of Yersinia enterocolitica on cysteine proteases of the papain family. AB - Cysteine proteases of the papain family, including mammalian cathepsins, play important physiological roles, however, their excessive activity may contribute to the development of various pathologies. Therefore, cysteine cathepsin inhibitors are being considered as promising drugs to treat cathepsin-driven diseases. Diverse saprophytic and parasitic microbes produce such inhibitors, which target the host's proteases playing pivotal roles in immune responses, thus leading to the survival of microbes within their host. Yersinia enterocolitica is a Gram-negative zoopathogenic coccobacillus, which has developed several mechanisms to evade the host's immune system. Nevertheless, the bacterium has not yet been shown to produce any cysteine protease inhibitors. Here we demonstrate that Y. enterocolitica strains of different bioserotypes and genotypes synthesize papain and human cathepsin L inhibitors, but not bovine cathepsin B inhibitors. By employing fluorimetry and zymography, the cell-surface inhibitors were shown to associate peripherally with the outer membrane, while the inhibitors present in cell-free extracts proved to: interact reversibly with their target enzymes, exhibit thermolability and stability in a range of pH values (5-9), and have high molecular weights. Batch affinity chromatography on papain-agarose resin was then undertaken to isolate putative inhibitors of cysteine proteases from the bacterial extract. The isolated 18 kDa protein was identified by LC-MS/MS as the periplasmic chaperone Skp. The Skp-containing eluate inhibited the activity of cysteine cathepsins produced by human dermal fibroblasts. The homologous Skp protein was also isolated from the extract of Escherichia coli. Our results point to a possible new biological role of the bacterial chaperone Skp. PMID- 29458858 TI - Monitoring biocalcification potential of Lysinibacillus sp. isolated from alluvial soils for improved compressive strength of concrete. AB - The present study reports the potential of newly isolated calcite precipitating bacteria isolated from alluvial soil to improve the strength and durability of concrete. A total of sixteen samples of alluvial soil and sewage were collected from the different locations of province Solan (India). For isolation, enrichment culture technique was used to enrich calcite precipitating strains in Urea broth. After enrichment, fourteen distinct bacterial strains were obtained on Urea agar. Based on qualitative and quantitative screening for urease activity, five isolates were obtained possessing higher calcite formation and urease activities (38-77 MUmhos/cm) as compared with standard strain of Bacillus megaterium MTCC 1684 (77 MUmhos/cm). An isolate I13 identified as Lysinibacillus sp. was selected for self healing property in the concrete mix of M20. An improved compressive strength of 1.5 fold was observed in concrete samples amended with Lysinibacillus sp. over the concrete amended with B. megaterium MTCC 1684 after 28 days of curing. The higher calcite precipitation activity was indicated in Lysinibacillus sp. by FE-SEM micrographs and EDX analysis. PMID- 29458859 TI - The opportunistic human fungal pathogen Candida albicans promotes the growth and proliferation of commensal Escherichia coli through an iron-responsive pathway. AB - Candida albicans is a commensal fungal species that commonly colonizes a heterogeneous mixture of human body where it intimately interacts with other microbes in the host environment such as the gastrointestinal (GI) tract. Most studies in fungal-bacterial interactions are about synergistic or antagonistic effects of bacterial functions on fungal physiological activities including pathogenicity. Very few studies have been demonstrated about the role of fungi on bacteria. In this study, we investigated the interactions between C. albicans and the bacterium Escherichia coli and unexpectedly observed that C. albicans enhances growth and proliferation of Escherichia coli strain K12 by facilitating its cell division. Importantly, we found, based on our genetic screens, that both fungus- and bacterium-derived factors, including the iron-responsive transcription factors Sef1 and Sfu1 in C. albicans and the siderophere enterobactin transporters FepD and FepG in E. coli, actively contribute to this transkingdom interaction. Deletion of SFU1 or SEF1 caused a dramatic reduction in growth enhancement of E. coli. Compared to the wild type E. coli, the enhanced growth of both fepD and fepG null mutants were largely dampened. However, the E. coli mutant lacking entB, a key enzyme catalyzing the biosynthesis of siderophore enterobactin, showed similar growth enhancement as the wild type when co inoculated with C. albicans. C. albicans promotes growth and proliferation of the commensal bacterium E. coli and an iron-responsive signaling pathway appears to be required. C. albicans may act to supply a siderophere-like molecule that captures the environmental iron to promote the growth of E. coli. Our studies gave insight into a novel interacting mechanism operative in interspecies communication that occurs when bacteria and fungi co-exist. PMID- 29458860 TI - Could FlhF be a key element that controls Campylobacter jejuni flagella biosynthesis in the initial assembly stage? AB - The disordered arrangement of flagella biosynthetic genes, combined with a simplified regulatory mechanism, has made elucidating the process of Campylobacter jejuni flagellation difficult. FlhF is a recently identified element that controls the assembly of the flagella, although its function mechanism and regulatory preference are not well defined at present. In this study, we found that inactivation of FlhF caused the transcription of most flagella genes down-regulated. The importance of FlhF was systematically evaluated by analyzing changes in the transcription profiles between wild-type and flhF mutant strains, which showed that FlhF affects late flagella genes obviously. FlhF is constitutively expressed during C. jejuni growth, demonstrating that it is a class I flagella element that participates in early flagella assembly. In addition, the early flagella component FlhB was not localized to the cell pole in the flhF mutant. Thus, flagella assembly was impeded at the initial stage. We propose a model in which FlhF helps target the early flagella components to the cell pole, functioning prior to the formation of the flagella export apparatus, and thus places FlhF at the top of the flagella regulatory cascade hierarchy. Inactivation of FlhF impeded flagella assembly at the initial stage and decreased transcription of flagella genes through a feed back control mechanism, leading to FlhF having a significant influence on the expression of late flagella components and resulting in the aflagellate C. jejuni phenotype. Our present study has uncovered how FlhF influences C. jejuni flagella biosynthesis, which will be helpful in understanding the C. jejuni flagella biosynthetic pathway and bacterial flagellation in general. PMID- 29458861 TI - First report of a cross-kingdom pathogenic bacterium, Achromobacter xylosoxidans isolated from stipe-rot Coprinus comatus. AB - Coprinus comatus is an edible mushroom widely cultivated in China as a delicious food. Various diseases have occurred on C. comatus with the cultivated area increasing. In this study, the pathogenic bacterium JTG-B1, identified as Achromobacter xylosoxidans by 16S rDNA and nrdA gene sequencing, was isolated from edible mushroom Coprinus comatus with serious rot disease on its stipe. A. xylosoxidans has been confirmed as an important opportunistic human pathogenic bacterium and has been isolated from respiratory samples from cystic fibrosis. It is widely distributed in the environment. Here, we first report that fungi can also serve as a host for A. xylosoxidans. We confirmed that it can cross-kingdom infect between animals (mice) and fungi (C. comatus). The results of pathogenicity tests, physiological, biochemical and genotyping analysis of A. xylosoxidans from different hosts suggested that different strain of A. xylosoxidans may have pathogenicity differentiation. A. xylosoxidans not only is pathogenic to C. comatus but also may threaten human health. PMID- 29458862 TI - Comparative transcriptomic analysis of Cerrena unicolor revealed differential expression of genes engaged in degradation of various kinds of wood. AB - To explore the number of enzymes engaged by Cerrena unicolor FCL139 for wood degradation, the transcriptomes of the fungus growing on birch, ash, maple sawdust and the control liquid medium were analyzed. Among 12,966 gene models predicted for the C. unicolor genome, 10,396 all-unigenes were detected, of which 9567 were found to be expressed in each of the tested growth media. The highest number (107) of unique transcripts was detected during fungus growth in the control liquid medium, while the lowest number (11) - in the fungal culture comprising maple saw dust. Analysis of C. unicolor transcriptomes identified numerous genes whose expression differed substantially between the mycelia growing in control medium and each of the sawdust media used, with the highest number (828) of upregulated transcripts observed during the fungus growth on the ash medium. Among the 294 genes that were potentially engaged in wood degradation, the expression of 59 was significantly (p < .01) changed in the tested conditions. The transcripts of 37 of those genes were at least four times more abundant in the cells grown in all sawdust media when compared to the control medium. Upregulated genes coding for cellulases and, to a lower extent, hemicellulases predominated during fungus growth on sawdust. Transcripts encoding cellulolytic enzymes were the most abundant in mycelia grown on birch and maple while lower number of such transcripts was detected in fungus growing on ash. The expression pattern of lignolytic activities-coding genes was strongly dependent on the type of sawdust applied for fungus growth medium. PMID- 29458863 TI - Genetic manipulation of Fonsecaea pedrosoi using particles bombardment and Agrobacterium mediated transformation. AB - Fonsecaea pedrosoi, a melanized fungal pathogen that causes Chromoblastomycosis, a human disease with a worldwide distribution. Biolistic is a widely used technique for direct delivery of genetic material into intact cells by particles bombardment. Another well-established transformation method is Agrobacterium mediated transformation (ATMT), which involves the transfer of a T-DNA from the bacterium to the target cells. In F. pedrosoi there are no reports of established protocols for genetic transformation, which require optimization of physical and biological parameters. In this work, intact conidia of F. pedrosoi were particle bombarded and subjected to ATMT. In addition, we proposed hygromycin B, nourseothricin and neomycin as dominant selective markers for F. pedrosoi and vectors were constructed. We tested two parameters for biolistic: the distance of the particles to the target cells and time of cells recovery in nonselective medium. The biolistic efficiency was 37 transformants/MUg of pFpHYG, and 45 transformants/MUg of pAN7.1. Transformants expressing GFP were successfully obtained by biolistic. A co-culture ratio of 10: 1 (bacterium: conidia) and co incubation time of 72 h yielded the largest number of transformants after ATMT. Southern blot analysis showed the number of foreign DNA insertion into the genome is dependent upon the plasmid used to generate the mutants. This work describes for the first time two efficient methods for genetic modification of Fonsecaea and these results open new avenues to better understand the biology and pathogenicity of the main causal agent of this neglected disease. PMID- 29458864 TI - Functional analysis of an APSES transcription factor (GlSwi6) involved in fungal growth, fruiting body development and ganoderic-acid biosynthesis in Ganoderma lucidum. AB - The APSES transcription factors have been identified as key regulators of fungal development and other biological processes in fungi. In the present study, the function of Ganoderma lucidum GlSwi6, a homolog of Saccharomyces cerevisiae Swi6, was characterized. RNAi was used to examine the function of GlSwi6 in G. lucidum. Silencing GlSwi6 resulted in multiple developmental defects, including reduced fungal growth and increased hyphal branching, and the GlSwi6-silenced strains did not exhibit primordium or fruiting body formation. In addition, the H2O2 and ganoderic-acid (GA) levels of the GlSwi6-silenced strains decreased approximately 50% and 25%, respectively, compared with those of the WT strain. Furthermore, the addition of H2O2 led to the recovery of the GA levels of GlSwi6-silenced strains, implying that GlSwi6 might regulate GA biosynthesis by regulating the intracellular ROS levels. Taken together, these results indicate that GlSwi6 is involved in fungal growth, development and GA biosynthesis in G. lucidum. PMID- 29458865 TI - Diversity and bioprospecting of extremely halophilic archaea isolated from Algerian arid and semi-arid wetland ecosystems for halophilic-active hydrolytic enzymes. AB - The diversity of haloarchaea associated with different dry salt lakes in northeastern Algeria was investigated together with their potential of hydrolytic enzyme production. A total of 68 aerobic halophilic archaea were isolated from saline sediments. Based on the 16S rRNA gene sequencing, the isolates were assigned to seven phylotypes within the class Halobacteria, namely Haloarcula, Halococcus, Haloferax, Halogeometricum, Haloterrigena, Natrialba, and Natrinema. The results showed that Haloferax group was found to be dominant in all samples (30 isolates) (44%) with high diversity, followed by Halococcus spp. (13%) (9 isolates). All phylotypes are extreme halophiles and thermotolerant with the ability to grow at temperatures up to 48 degrees C. In addition, the screening for extracellular halophilic enzymes showed that 89.7% of the isolates were able to produce at least two types of the screened enzymes. The strains producing esterase, gelatinase, inulinase, cellulase and protease activities were the most diverse functional group. These data showed an abundant and diverse haloarchaeal community, detected in Algerian wetland ecosystems, presenting a promising source of molecules with important biotechnological applications. PMID- 29458866 TI - Reactive oxygen species-independent apoptotic pathway by gold nanoparticles in Candida albicans. AB - Candida albicans is the most common pathogenic fungus in humans, causing cutaneous and life-threatening systemic infections. In this study, we confirmed using propidium iodide influx that gold nanoparticles (AuNPs), which are promising materials for use as antimicrobial agents, did not affect the membrane permeability of C. albicans. Thus, the fungal cell death mechanisms induced by AuNPs were assessed at intracellular levels including DNA damage, mitochondrial dysfunction, and reactive oxygen species (ROS) overproduction. AuNPs interacted with C. albicans DNA leading to increased nuclear condensation and DNA fragmentation. Changes in the mitochondria induced by AuNPs involving mass, Ca2+ concentrations, and membrane potential indicated dysfunction, though the level of intracellular and mitochondrial ROS were maintained. Although ROS signaling was not disrupted, DNA damage and mitochondrial dysfunction triggered the release of mitochondrial cytochrome c into the cytosol, metacaspase activation, and phosphatidylserine externalization. Additionally, the AuNPs-induced apoptotic pathway was not influenced by N-acetylcysteine, an ROS scavenger. This indicates that ROS signaling is not linked with the apoptosis. In conclusion, AuNPs induce ROS-independent apoptosis in C. albicans by causing DNA damage and mitochondria dysfunction. PMID- 29458867 TI - Does plant-Microbe interaction confer stress tolerance in plants: A review? AB - The biotic and abiotic stresses are major constraints for crop yield, food quality and global food security. A number of parameters such as physiological, biochemical, molecular of plants are affected under stress condition. Since the use of inorganic fertilizers and pesticides in agriculture practices cause degradation of soil fertility and environmental pollutions. Hence it is necessary to develop safer and sustainable means for agriculture production. The application of plant growth promoting microbes (PGPM) and mycorrhizal fungi enhance plant growth, under such conditions. It offers an economically fascinating and ecologically sound ways for protecting plants against stress condition. PGPM may promote plant growth by regulating plant hormones, improve nutrition acquisition, siderophore production and enhance the antioxidant system. While acquired systemic resistance (ASR) and induced systemic resistance (ISR) effectively deal with biotic stress. Arbuscular mycorrhiza (AM) enhance the supply of nutrients and water during stress condition and increase tolerance to stress. This plant-microbe interaction is vital for sustainable agriculture and industrial purpose, because it depends on biological processes and replaces conventional agriculture practices. Therefore, microbes may play a key role as an ecological engineer to solve environmental stress problems. So, it is a feasible and potential technology in future to feed global population at available resources with reduced impact on environmental quality. In this review, we have attempted to explore about abiotic and biotic stress tolerant beneficial microorganisms and their modes of action to enhance the sustainable agricultural production.

PMID- 29458868 TI - Stress response of a clinical Enterococcus faecalis isolate subjected to a novel antimicrobial surface coating. AB - Emerging antibiotic resistance among pathogenic bacteria, paired with their ability to form biofilms on medical and technical devices, represents a serious problem for effective and long-term decontamination in health-care environments and gives rise to an urgent need for new antimicrobial materials. Here we present the impact of AGXX(r), a novel broad-spectrum antimicrobial surface coating consisting of micro-galvanic elements formed by silver and ruthenium, on the transcriptome of Enterococcus faecalis. A clinical E. faecalis isolate was subjected to metal stress by growing it for different periods in presence of the antimicrobial coating or silver-coated steel meshes. Subsequently, total RNA was isolated and next-generation RNA sequencing was performed to analyze variations in gene expression in presence of the antimicrobial materials with focus on known stress genes. Exposure to the antimicrobial coating had a large impact on the transcriptome of E. faecalis. After 24min almost 1/5 of the E. faecalis genome displayed differential expression. At each time-point the cop operon was strongly up-regulated, providing indirect evidence for the presence of free Ag+-ions. Moreover, exposure to the antimicrobial coating induced a broad general stress response in E. faecalis. Genes coding for the chaperones GroEL and GroES and the Clp proteases, ClpE and ClpB, were among the top up-regulated heat shock genes. Differential expression of thioredoxin, superoxide dismutase and glutathione synthetase genes indicates a high level of oxidative stress. We postulate a mechanism of action where the combination of Ag+-ions and reactive oxygen species generated by AGXX(r) results in a synergistic antimicrobial effect, superior to that of conventional silver coatings. PMID- 29458870 TI - Rapid screening of starter cultures for maari based on antifungal properties. AB - Forty Bacillus isolates obtained from maari (used as condiment in Burkina Faso) including 17 B. subtilis, 4 B. circulans, 7 B. pumilus and 6 B. licheniformis were investigated for use as starter cultures in maari production. The isolates were screened by PCR for the sfp gene responsible for the production of the lipopeptide biosurfactant, surfactin. The sfp gene was detected in all of the seventeen B. subtilis isolates, in 2 out of 7 B. pumilus, in 4 out of 6 B. licheniformis whereas no B. circulans was positive for the sfp gene by PCR screening. Furthermore, all the 40 Bacillus spp. were screened for biosurfactant production and inhibitory activity against Aspergillus flavus, A. niger, A. versicolor and Rhizopus oryzae. Results demonstrated a relationship between the presence of the sfp gene and the antifungal activity and biosurfactant production of Bacillus isolates. In addition, molecular typing of the 17 B. subtilis isolates by Multilocus Sequence Typing (MLST) resulted in 15 Sequence Types, one of them included three strains. Randomly Amplified Polymorphic DNA-PCR (RAPD PCR), used for B. licheniformis, B. megaterium, B. circulans and B. pumilus revealed that the inhibitory activity and biosurfactant production were strain dependent. Finally, the detection of chitinase (chi) and beta-glucanase (glu) biosynthesis genes was found to be associated with the antifungal activity for 16 B. subtilis isolates. The present work provides a greater understanding of the antifungal activity and biosurfactant production ability within the Bacillus spp. isolated from maari and contributes to the selection of Bacillus isolates to be used as starter cultures for controlled production of maari. PMID- 29458871 TI - DNA sequence-specific dimeric bisbenzimidazoles DBP(n) and DBPA(n) as inhibitors of H-NS silencing in bacterial cells. AB - DNA sequence-specific fluorescent dimeric bisbenzimidazoles DBP(n) and DBPA(n), noncovalently interacting with A-T pairs in the minor groove of double-stranded DNA were used for studying and monitoring the expression of histone-like H-NS dependent promoters. Histone-like H-NS selectively binds to AT-rich segments of DNA and silences a large number of genes in bacterial chromosomes. The H-NS dependent promoters of Quorum Sensing (QS)-regulated lux operons of the marine bacteria mesophilic Aliivibrio fischeri, psychrophilic Aliivibrio logei were used. Escherichia coli lux biosensors were constructed by cloning fragments bearing QS-regulated promoters into the vector, thereby placing each fragment upstream of the promoterless Photorhabdus luminescens luxCDABE genes. It was shown that the dimeric bisbenzimidazoles DBP(n) and DBPA(n) counteract the H-NS silencing activity. Thus, the presence of DBP(n) or DBPA(n) in the medium leads to an approximately 10-100-fold increase in the level of transcription of QS promoters in E. coli hns+. The largest decrease in the level of H-NS repression was observed using ligands containing a linker with a length of ca. 18A, such as DBP(2) and DBPA(2). Ligands containing linkers with n=1 and 3 are an order of magnitude less active; ligands with n=4 are inactive. DBPA(2) exhibits activity starting with a concentration of 0.5MUM; the minimum concentration of DBP(2) is 5 7 times higher. It is suggested that A-T pairs located at five nucleotide pair intervals, which correspond to the linker length in highly active ligands with n=2, play a key role in the structure of H-NS-binding sites in QS-regulated promoters.

AB - Endophytic bacteria occupy the same niche of phytopathogens and may produce metabolites that induce the host plant systemic resistance and growth. Host and environmental variables often determine the endophytic community's structure and composition. In this study, we addressed whether the plant genotype, organ, and geographic location influence the structure, composition, and functionality of endophytic bacterial communities in Paullinia cupana. To characterize the communities and identify strains with potential application in agriculture, we analyzed two P. cupana genotypes cultivated in two cities of the State of Amazonas, Brazil. Endophytic bacteria were isolated from surface-disinfested root, leaf, and seed tissues through the fragmentation and maceration techniques. The colonization rate, number of bacteria, richness, diversity, and functional traits were determined. The plant growth-promoting ability of selected bacterial strains was assessed in Sorghum bicolor. We identified 95 bacterial species distributed in 29 genera and 3 phyla (Proteobacteria, Actinobacteria, and Firmicutes). The colonization rate, richness, diversity, and species composition varied across the plant organs; the last parameter also varied across the plant genotype and location. Some strains exhibited relevant plant growth-promoting traits and antagonistic traits against the main phytopathogens of P. cupana, but they were not separated by functional traits. The main bacterial strains with plant growth-promoting traits induced S. bicolor growth. Altogether, our findings open opportunities to study the application of isolated endophytic bacterial strains in the bioprospection of processes and products.

AB - Yeast is very well known eukaryotic organism for its remarkable biodiversity and extensive industrial applications. Saccharomyces cerevisiae is one of the most widely used microorganisms in biotechnology with successful applications in the biochemical production. Biological conversion with the focus on the different utilization of renewable feedstocks into fuels and chemicals has been intensively investigated due to increasing concerns on sustainability issues worldwide. Compared with its counterparts, Saccharomyces cerevisiae, the baker's yeast, is more industrially relevant due to known genetic and physiological background, the availability of a large collection of genetic tools, the compatibility of high density and large-scale fermentation, and optimize the pathway for variety of products. Therefore, S. cerevisiae is one of the most popular cell factories and has been successfully used in the modern biotech industry to produce a wide variety of products such as ethanol, organic acids, amino acids, enzymes, and therapeutic proteins. This study explores how different sustainable solutions used to overcome various environmental effects on yeast. This work targets a broad matrix of current advances and future prospect in yeast biotechnology and discusses their application and potential in general. PMID- 29458875 TI - Clinical and genetic-epignetic aspects of recurrent hydatidiform mole: A review of literature. AB - Hydatidiform Mole (HM) is the most common form of Gestational Trophoblastic Disease (GTD), defined by hyper-proliferation of trophoblastic cells. HM is typified as abnormal proliferation of extraembryonic trophoblastic (placental) tissues and failure of embryonic tissues development and is the only GTD with Mendelian inheritance, which can reoccur in different pregnancies. Moles are categorized into Complete Hydatidiform Moles (CHM) or Partial Hydatidiform Moles (PHM) and a rare familial trait, which forms a CHM and despite having androgenetic pattern, shows normal biparental inheritance, conceived from one sperm and egg. Recessive maternal-effect mutations in NLRP7 (NACHT, leucine rich repeat and PYD containing 7) and KHDC3L (KH Domain Containing 3-Like) genes have been shown to be responsible for Recurrent Hydatidiform Moles (HYDM1 MIM# 231090 when is caused by mutation in the NLRP7 gene and HYDM2 MIM#614293 when is caused by mutation in the KHDC3L gene). Methylation aberration in multiple maternally imprinted genes is introduced as the cause of Recurrent HYDM pathology. The current article reviews the histopathology, risk factors, and genetic and epigenetic characteristics of Recurrent HYDMs. PMID- 29458874 TI - Comparative analysis of gut bacterial communities of green turtles (Chelonia mydas) pre-hospitalization and post-rehabilitation by high-throughput sequencing of bacterial 16S rRNA gene. AB - Stranded green turtles (Chelonia mydas) are often cared for in rehabilitation centers until they recover. Although the specific causal agents of diseases in stranded turtles are difficult to diagnose, we know that gut microbiota of green turtles play a vital role in health as well as a wide range of diseases. The objective of this study was to characterize and compare the gut bacterial communities between pre-hospitalization (PH) and post-rehabilitation (PR) stranded green turtles using high-throughput sequencing analysis targeting V1-V3 regions of the bacterial 16S rRNA gene. A total of eight cloacal swab samples were collected from four green turtles undergoing rehabilitation. Proteobacteria dominating in both PH and PR samples without any significant difference. Firmicutes was the second and Bacteroidetes was the third most abundant phylum in PH samples, while Bacteroidetes prevailed in PR samples, followed by Firmicutes. The predominance of the genus Bacteroides in both PH and PR samples indicates the importance of this genus in turtle gut health. At a class level, Epsilonproteobacteria was significantly (P<0.05) associated with PH samples and Deltaproteobacteria predominated (P<0.05) in PR samples. The significant abundance of Campylobacter fetus, Escherichia coli, Clostridium botulinum and Vibrio parahaemolyticus in PH samples indicate pathogenic associations with stranded green turtles with zoonotic potential. The presence of Salmonella enterica in only PR samples suggest possible acquisition of this bacteria during rehabilitation. In this study, all post-rehabilitation green turtles exhibited similar bacterial communities, irrespective of their microbial compositions at pre-hospitalization. The marked differences in the gut bacterial communities of PH and PR turtles indicate the outcome of dietary, management and environmental shift during rehabilitation. Therefore, it is important to address the process of restoring normal gut microbiota of recovered turtles prior to release back to their natural habitat. PMID- 29458876 TI - Bone densitometry status and its associated factors in peri and post menopausal females: A cross sectional study from a tertiary care centre in India. AB - OBJECTIVE: Osteoporosis is a skeletal disorder characterized by diminished bone strength that increases the risk of fracture at instances of trivial trauma. Asians have a lower bone mass than the west. The present study was designed to add data from India on women above the age of 40 years with respect to low bone mineral density (BMD) and its associated high risk factors. MATERIALS AND METHODS: After a written informed consent, a detailed history was taken. Basal metabolic index was recorded, and biochemical and endocrine tests were done, followed by dual X ray absorptiometry scan. RESULTS: Average age of the study population was 46.54 years and BMI 26.58. The prevalence of osteopenia in the study was 36%, and that of osteoporosis, 4%; the overall prevalence of low BMD being 40%. Proportion of women with low BMD increased with advancing age and menopausal status. On endocrine evaluation, 53.44% cases with insufficient vitamin D, 62.5% with hyperparathyroidism, 100% with hypothyroidism, 75% with hyperthyroidism suffered from low BMD. Among chronic diseases, 75% women with diabetes, 33.3% with hypertension, 25% with deranged liver function and 50% with rheumatoid arthritis were found to have low BMD. 46.75% women with sun exposure less than one hour daily had poor bone mineralization. The proportion of women with normal BMD decreased from 84.09% to 43.33% with decrease in daily physical work. On logistic regression analysis, insufficient serum vitamin D concentrations, less physical work and inadequate sun exposure were found to be significantly associated with low BMD. CONCLUSION: Low BMD is not a disorder confined to postmenopausal women alone. It is widely prevalent in women above 40 years of age. Screening women above 40 in the absence of any high risk factors has the potential of nipping this silent killer in the bud. PMID- 29458877 TI - 1p deletion syndrome: A prenatal diagnosis characterized by an abnormal 1st trimester combined screening test, yet a normal NIPT result. AB - OBJECTIVE: To present a case with prenatal diagnosis and cytogenetic characterization of 1p36 deletion syndrome whose first trimester combined testing is abnormal but a normal NIPT result. CASE REPORT: A 33-year-old had an abnormal 1st trimester fetal aneuploidy screening result, but no trisomies 13, 18, 21 were detected by the noninvasive prenatal testing. Amniocentesis was performed after ultrasound showed fetal ventriculomegaly and echogenic bowel. The final conventional cytogenetics revealed a karyotype of 46, XX, del(1)(p36). CONCLUSION: Every prenatal genetic screening test and diagnostic procedure has its benefit and risk. NIPT offers better sensitivity and specificity for trisomies 13, 18, and 21. Even so, for primary population screening, NIPT provides lower detection rate than sequential screening if considering detection of all chromosomal abnormalities. Diagnostic testing should be offered rather than cell-free DNA screening to pregnant women if a fetal structural anomaly is identified on ultrasound examination. PMID- 29458878 TI - Variations in clinical presentation of unicornuate uterus with non-communicating rudimentary horn (class IIB of the American Fertility Society classification). AB - OBJECTIVE: The unicornuate uterus is a rare uterine malformation (2.4-13.7% of all uterine malformations (Engmann et al., 2004)) which usually features a rudimentary accessory horn in more than 75% of the cases. Pregnancy in the rudimentary horn is rare, but the complications attached to such pregnancies could be defined as the first clinical manifestation of rudimentary horn. CASE REPORTS: We hereby describe five cases of unicornuate uterus with rudimentary horn (UUWRH), each one with a different clinical presentation and without any correct preoperative diagnosis, and henceforth reflect on the practical aspects learnt about the differential diagnosis and management of this rare malformation. CONCLUSION: Our experience with UUWRH is that perhaps asymptomatic cases are not as rare as reported in medical literature. We highlight the need for a greater awareness of the differential diagnosis of genital malformations and accurate in the exact subtype and their correct treatment. PMID- 29458879 TI - A case of rapidly-growing atypical polypoid adenomyoma which was histologically diagnosed before operation and removed by a laparoscopic resection. AB - OBJECTIVE: Atypical polypoid adenomyoma (APAM) is an epithelial-mesenchymal mixed tumor which often develops in the uterine cavity of reproductive age women, requiring preservation of the reproductive functions. Preoperative endometrial biopsy may not yield histological diagnosis as the tumor is a solid smooth muscle tumor. The standard treatment option is a hysteroscopic resection for the diagnosis and the treatment at the same time. CASE REPORT: We report a case of rapidly-growing APAM successfully diagnosed preoperatively via transcervical punch biopsy followed by a laparoscopic resection. The mass was relatively large, had been located in the lower segment of the uterus, and the area of contact with the muscular layers was large. It was a complete removal and no recurrence had been observed 9 months after the operation. CONCLUSION: This is the first report of APAM treated by laparoscopic resection. The method may be a useful alternative when hysteroscopic surgery is inappropriate. PMID- 29458880 TI - Prenatal diagnosis of hydrancephaly and enlarged cerebellum and cisterna magna in a fetus with thanatophoric dysplasia type II and a review of prenatal diagnosis of brain anomalies associated with thanatophoric dysplasia. AB - OBJECTIVE: We present prenatal diagnosis of hydrancephaly and enlarged cerebellum and cisterna magna in a fetus with thanatophoric dysplasia type II (TD2) and a review of prenatal diagnosis of brain anomalies associated with TD. CASE REPORT: A 33-year-old woman was referred for genetic counseling at 25 weeks of gestation because of fetal ultrasound abnormalities. Prenatal ultrasound at 14 weeks of gestation revealed an increased nuchal translucency (NT) and hydrocephalus. Level II ultrasound examination at 25 weeks of gestation revealed hydrancephaly, macrocephaly, a cloverleaf skull, frontal bossing, enlarged cerebellum and cisterna magna, a narrow chest, small ribs, short straight limbs. Amniocentesis revealed a karyotype of 46,XX. FGFR3 mutation analysis using the DNA extracted from uncultured amniocytes revealed a genotype of WT/c.1948A>G (p.Lys650Glu). The result was consistent with a K650E mutation in FGFR3 and TD2. The pregnancy was subsequently terminated. CONCLUSION: Fetuses with TD2 may present increased NT, early onset hydrocephalus, enlarged cerebellum and cisterna magna, and hydrancephaly on prenatal ultrasound. PMID- 29458881 TI - Prenatal diagnosis of short-rib polydactyly syndrome type III or short-rib thoracic dysplasia 3 with or without polydactyly (SRTD3) associated with compound heterozygous mutations in DYNC2H1 in a fetus. AB - OBJECTIVE: We present the perinatal imaging findings and molecular genetic analysis in a fetus with short-rib polydactyly syndrome (SRPS) type III or short rib thoracic dysplasia 3 with or without polydactyly (SRTD3). CASE REPORT: A 29 year-old, primigravid woman was referred for genetic counseling at 15 weeks of gestation because of abnormal ultrasound findings of short limbs, a narrow chest and bilateral polydactyly of the hands and feet, consistent with a diagnosis of SRPS type III. Chorionic villus sampling was performed, and targeted next generation sequencing (NGS) was applied to analyze a panel of 25 genes including CEP120, DYNC2H1, DYNC2LI1, EVC, EVC2, FGFR2, FGFR3, HOXD10, IFT122, IFT140, IFT172, IFT52, IFT80, KIAA0586, NEK1, PAPSS2, SLC26A2, SOX9, TCTEX1D2, TCTN3, TTC21B, WDR19, WDR34, WDR35 and WDR60. The NGS analysis identified novel mutations in the DYNC2H1 gene. The fetus was compound heterozygous for a missense mutation c.8077G > T (p.Asp2693Tyr) of paternal origin in DYNC2H1 and a frameshift mutation c.11741_11742delTT (p.Phe3914X) of maternal origin in DYNC2H1. The fetus had a karyotype of 46,XY, and postnatally manifested characteristic SRPS type III phenotype. CONCLUSION: Targeted NGS is useful in genetic diagnosis of fetal skeletal dysplasia and SRPS, and the information acquired is helpful in genetic counseling. PMID- 29458882 TI - Prenatal diagnosis of a 0.7-Mb 17p13.3 microdeletion encompassing YWHAE and CRK but not PAFAH1B1 in a fetus without ultrasound abnormalities. AB - OBJECTIVE: We present prenatal diagnosis and molecular cytogenetic characterization of 17p13.3 microdeletion encompassing YWHAE and CRK but not PAFAH1B1 in a fetus without ultrasound abnormalities. CASE REPORT: A 33-year-old woman underwent amniocentesis at 17 weeks of gestation because of a family history of spinocerebellar atrophy in the husband. Amniocentesis revealed a karyotype of 46,XX. Simultaneously array comparative genomic hybridization (aCGH) analysis (using 60,000 probes) revealed a 0.7-Mb 17p13.3 microdeletion or arr 17p13.3 (1,264,243-1,965,733) * 1 dn [GRCh37 (hg19)] encompassing YWHAE and CRK but not PAFAH1B1. Prenatal ultrasound findings were unremarkable. There were no structural abnormalities of the brain, heart, kidneys, skull, limbs and other internal organs. The parents elected to terminate the pregnancy, and a 268-g fetus was delivered at 19 weeks of gestation with mild facial dysmorphism. Postnatal high-resolution aCGH analysis of the placenta (using 630,000 probes) showed a 0.79-Mb 17p13.3 microdeletion or arr 17p13.3 (1,173,549-1,970,690) * 1 (hg19) encompassing TUSC5, YWHAE, CRK and HIC1 but not PAFAH1B1. Metaphase fluorescence in situ hybridization analysis using the 17p13.3-specific probe of RP11-818O24 revealed a 17p13.3 deletion. CONCLUSION: Fetus with 17p13.3 microdeletion without involving PAFAH1B1 may present no brain abnormalities on fetal ultra sound. PMID- 29458883 TI - Maternal and fetal outcomes in pregnancies with pulmonary hypertension: Experience of a tertiary center. AB - OBJECTIVE: Pregnancies complicated with PHT are serious debates for obstetricians due to high maternal and fetal complication potentials. The aim of the study was to present our maternofetal outcomes in pregnant women with pulmonary hypertension. MATERIALS AND METHODS: This study was performed using data extracted from the medical files of 23 pregnancies of 18 patients with PHT who were followed-up in the obstetrics and gynecology department. RESULTS: The average age was 27.09 +/- 6.97 (range: 14-38) years. The most frequent maternal cardiac pathologies were cardiac valvular disease (mitral or aortic insufficiency) (n = 4), atrial septal defect (n = 3), mitral stenosis (n = 3), ventricular septal defect (n = 2) and arrhythmia (n = 2). Caesarean section and normal vaginal delivery were performed in 13 and 7 deliveries, respectively. Therapeutic dilatation and curettage was performed in 3 patients. Preterm delivery occurred in 4 pregnancies and there were 2 intrauterine growth retardations, 1 preeclampsia and 2 maternal pulmonary edemas. One patient underwent re-laparotomy 5 days after delivery due to uterine hematoma. Totally, 20 newborns (14 female, 6 male) were delivered. Most of the complications were seen in advanced PHT classes. CONCLUSION: The care of the pregnant women with PHT necessitates a well-planned, multidisciplinary approach focusing on close monitoring before, during and after delivery. This approach may contribute to reduction of poor maternal and fetal outcomes. PMID- 29458884 TI - Late-onset fetal bilateral pleural effusions associated with Down syndrome. AB - OBJECTIVE: We present two cases of late-onset bilateral fetal pleural effusions associated with fetal Down syndrome. CASE REPORTS: Case 1. A 33-year-old Vietnamese woman had undergone regular sonographic examinations since 23 weeks of gestation and no abnormality had been noted. However, bilateral moderate pleural effusions were found at 33 weeks of gestation, and massive pleural effusion, ascites and polyhydramnios developed at 34 weeks of gestation. Aspiration of the pleural effusion was subsequently performed. Clinical laboratory surveys of the aspiration fluid excluded toxoplasmosis and cytomegalovirus infection. Cytogenetic analysis of cultured lymphocytes derived from pleural effusion revealed a karyotype of 47,XX,+21. The parents elected to continue the pregnancy. Intrauterine fetal demise occurred at 37 weeks of gestation, and a macerated female baby was delivered. Postnatal cytogenetic analysis of the umbilical cord confirmed the prenatal diagnosis. Case 2. A 41-year-old Pakistani woman had undergone regular sonographic examinations and no abnormality had been noted. However, isolated bilateral mild pleural effusions were noted at 27 weeks of gestation. Amniocentesis revealed a karyotype of 47,XY,+21 and simultaneous array comparative genomic hybridization analysis of uncultured amniocytes confirmed the diagnosis of Down syndrome. The pregnancy was subsequently terminated. CONCLUSION: Fetuses with Down syndrome may present late-onset bilateral pleural effusions. Prenatal diagnosis of late-onset bilateral pleural effusions should raise the possibility of fetal Down syndrome and cytogenetic investigation is warranted. PMID- 29458885 TI - Prenatal diagnosis of fetal glutaric aciduria type 1 with rare compound heterozygous mutations in GCDH gene. AB - OBJECTIVE: Glutaric aciduria type 1 is a rare disease, with the estimated prevalence about 1 in 100,000 newborns. GCDH gene mutation can lead to glutaric acid and 3- OH glutaric acid accumulation, with clinical manifestation of neuronal damage, brain atrophy, microencephalic macrocephaly, decreased coordination of swallowing, poor muscle coordination, spasticity, and severe dystonic movement disorder. CASE REPORT: A 22-year-old female, Gravida 4 Para 2, is pregnancy at 13 weeks of gestational age. Her first child is normal, however, the second child was diagnosed as glutaric aciduria type I after birth. She came to our hospital for prenatal genetic counselling of her fetus at 13 weeks of gestational age. We performed GCDH gene mutation analysis of maternal blood showed IVS 3 + 1 G > A heterozygous mutation, GCDH gene mutation analysis of paternal blood showed c. 1240 G > A heterozygous mutation, and the second child has compound heterozygous IVS 3 + 1 G > A and c. 1240 G > A mutations. Later, we performed amniocentesis at 16 weeks of gestational age for chromosome study and GCDH gene mutation analysis for the fetus. The fetal chromosome study showed normal karyotype, however, GCDH gene mutation analysis showed compound heterozygous IVS 3 + 1 G > A and c. 1240 G > A mutations. The couple decided to termination of pregnancy thereafter. CONCLUSION: Glutaric acidemia type 1 is an autosomal recessive disorder because of pathogenic mutations in the GCDH gene. Early diagnosis and therapy of glutaric acidemia type 1 can reduce the risk of neuronal damage and acute dystonia. We report a case of prenatal diagnosis of fetal glutaric aciduria type 1 with rare compound heterozygous GCDH gene mutation at IVS 3 + 1 G > A and c. 1240 G > A mutations, which provide better genetic counselling for the couples. PMID- 29458886 TI - Laparoscopic en bloc resection of a para-cervical cancer with OHVIRA syndrome. AB - OBJECTIVE: There are some reports of cervical cancer with uterus didelphys but a case of clear cell carcinoma (CCCC) with Obstructed Hemivagina and Ipsilateral Renal Anomaly (OHVIRA) syndrome is extremely rare. The aim of this paper was to report a case of CCCC with OHVIRA syndrome and the difficulty in making a preoperative diagnosis. CASE REPORT: A 65 years old woman presented with postmenopausal bleeding and pelvic examination showed right paracervical mass. Preoperative confirmation of cervical carcinoma was difficult due to the location of the mass, which was inaccessible by cervical punch biopsy. Pelvic examination revealed a large mass in pelvic cavity without parametrial invasion and ultrasound showed approximately 70 mm cervical tumor. Laparoscopic surgery revealed clear cell carcinoma of the para-endocervix with OHVIRA syndrome. CONCLUSION: In the case of cervical carcinoma with OHVIRA syndrome, laparoscopic surgery is preferable for the diagnosis and management. PMID- 29458887 TI - Large cell neuroendocrine carcinoma of the endometrium: A case report and literature review. AB - OBJECTIVE: To report a case and review published cases of large cell neuroendocrine carcinoma (LCNEC) of the endometrium. CASE REPORT: A 51-year-old female presented with postmenopausal bleeding and a palpable pelvic mass. An endometrial biopsy showed a malignant mixed Mullerian tumor (MMMT). Suboptimal debulking surgery was performed. The final pathology revealed stage IVB endometrial LCNEC. Post-operative adjuvant chemotherapy with cisplatin and etoposide was administered. Two months after discontinuing adjuvant chemotherapy, salvage chemotherapy with cisplatin and ifosfamide was administered due to tumor progression; however, obstructive ileus was noted 2 months later. A segmental small bowel resection and palliative colostomy were performed. She died secondary to a post-operative infection 8 days after the operation. CONCLUSION: Endometrial LCNEC is a rare but aggressive disease. If diagnosed, combined therapies, including staging surgery, following by adjuvant radiotherapy and chemotherapy, should be performed. PMID- 29458889 TI - Pregnancy following robot-assisted laparoscopic partial cystectomy and gonadotropin-releasing hormone agonist treatment within three months in an infertile woman with bladder endometriosis. AB - OBJECTIVE: To report an infertility case of deep-infiltrating bladder endometriosis conceiving following robot-assisted surgery and modified gonadotropin-releasing hormone agonist (GnRHa) treatment. CASE REPORT: A 33 year old infertile female presenting with dysmenorrhea was found to have a bladder mass by pelvic ultrasound. Cystoscopy revealed a protruding tumor from the posterior bladder wall, and endometriosis was highly suspected. Robot-assisted laparoscopic partial cystectomy was performed for the deep-infiltrating bladder endometriosis. With postoperative half-dose GnRHa treatment and timed intercourse, she got pregnant within 3 months. CONCLUSION: Robot-assisted complete resection of deep-infiltrating endometriosis and bladder repair immediately followed by GnRHa therapy and medical assistance improves reproductive outcomes efficiently in women with endometriosis-associated infertility. PMID- 29458888 TI - Ureterovaginal fistula: A complication of a vaginal foreign body. AB - OBJECTIVE: To know the diagnostic tools and proper management of ureterovaginal fistula following neglected vaginal foreign body in order to achieve optimal outcome. CASE REPORT: A case of ureterovaginal fistula associated with a neglected vaginal foreign body. The patient was complaining of a foul-smelling vaginal discharge and lower abdominal pain. On vaginal examination, a hard and large foreign body was found. Examination under anesthesia was performed, and an aerosol cap was removed from her vagina. The patient developed urinary incontinence after removal of the foreign body. Subsequent work-up demonstrated the presence of a right ureterovaginal fistula. The patient underwent an abdominal ureteroneocystostomy. At one year follow up, the patient had fully recovered. CONCLUSION: Ureterovaginal fistula following neglected vaginal foreign body is a serious condition. Early diagnosis, treatment of infection and proper surgical management can improve the outcome and decrease complications. PMID- 29458890 TI - A vulvar mass as the first presentation in colorectal carcinoma: An unusual site of metastasis masquerading a primary cancer. AB - OBJECTIVE: To demonstrate a case with a vulvar metastasis masquerading a primary vulvar malignancy. The clinical and histological features, mechanism, and impact to the prognosis are discussed. CASE REPORT: A 58-year-old woman presented to gynecologist for abnormal vaginal discharge. A vulvar nodule was noticed during physical examination. Biopsy showed adenocarcinoma (ADC) and she was referred for further survey under the impression of Bartholin duct ADC. Later she was further found to also have a colorectal tumor with liver metastasis and subsequently received surgery under the suspicion of a double primary cancer involving the colon and vulva. The pathology revealed colorectal ADC with both hepatic and vulvar metastasis. CONCLUSION: Secondary tumor in female genital tract is unusual and vulvar metastasis is the rarest kind. The clinical manifestation may be perplexing especially if a patient is presented with a nonspecific gynecological symptom such as abnormal vaginal discharge without any past history.

PMID- 29458897 TI - Physical activities (exercises or choreses) during pregnancy and mode of delivery in nulliparous women: A prospective cohort study. AB - OBJECTIVE: The aim of this study was to investigate changes in physical activities during pregnancy and the relationship between physical activity and unplanned caesarean sections (CSs). MATERIALS AND METHODS: A cohort study design was carried out. A cohort of 2029 pregnant women was established when they received prenatal care at 18-22 weeks of gestation in a medical center in southwest Iran. Participants were asked to recall their levels of physical activity during pre-pregnancy. The data were processed using Statistics/Data Analysis. To compare activities the chi-square was used to identify significant differences between the groups. A multiple logistic regressian was used to identify the association between activities and delivery mode as well as controlling potential confounding variables. In the analyses, the level of significance was set at P < 0.05. RESULTS: In total, 2029 pregnant women participated in the study, among which 1334 (65.84%) underwent CSs and 692 (34.16%) underwent NVDs. The study indicated the odds ratio of CS was 0.68 (95% CI: 0.47-0.97) for a pregnant woman who increased her level of activity during pregnancy compared to pre-pregnancy. CONCLUSION: The results of this study showed that regular and standard physical activities during pregnancy can reduce the risk of caesarean section in pregnant women. These findings can be important in convincing health care providers to prescribe regular and standard physical activities for pregnant women during pregnancy. PMID- 29458898 TI - Serum decorin measurement in prediction of the risk for preterm birth. AB - OBJECTIVE: To define serum decorin (sDEC) levels in healthy pregnants and in patients with preterm labor (PTL), and to introduce possible role of sDEC in predicting the risk for preterm birth (PTB). MATERIALS AND METHODS: Thirty-one women with diagnosis of PTL between 24th to 32nd weeks of pregnancy were compared with 44 healthy pregnants in this prospective case-control study. Maternal blood sDEC and uterine cervical length (CL) measurements were conducted at referral. RESULTS: Median sDEC level was significantly decreased in PTL group (p = 0.013). Median CL was significantly shorter in PTL group (p < 0.001). There was not any correlation between sDEC level and maternal age, BMI, and gestational age at blood sampling time within PTL (p = 0.955, p = 0.609, p = 0.079, respectively) and control groups (p = 0.652, p = 0.131, and p = 0.921, respectively). There was not any association between sDEC level and PTB within 7 days, before 34th weeks, but before 37th weeks there was (p = 0.206, 0.091, and p = 0.026, respectively). There was not any correlation between sDEC level and the CL in PTL group (p = 0.056). CONCLUSIONS: sDEC has a limited effect in prediction of PTB within a week or before 34th weeks. Combination of sDEC with CL measurements predicted PTB before 37th weeks. CONCLUSION: PMID- 29458899 TI - Single port access laparoscopic subtotal hysterectomy using contained manual morcellation: Experience from a tertiary referral center in Taiwan. AB - OBJECTIVE: To describe the surgical outcomes of single port access laparoscopic subtotal hysterectomy (LSH) using in-bag manual morcellation and evaluate the feasibility of this procedure. MATERIALS AND METHODS: Thirty patients with symptomatic leiomyoma or adenomyosis were enrolled. A 2-cm transverse incision was made at the umbilicus and single port apparatus (LagiPort) was applied. After dissection of vesicouterine peritoneum from the uterus, the uterine ligaments and vessels were secured and transected by Gyrus PK cutting forceps. Cervical amputation at the level of internal os was made by SupraLoop (Karl Storz). The uterine corpus was put into an Endobag before morcellation. The opening of Endobag was exteriorized from the umbilical incision and the uterine corpus was removed in a contained manner by manual morcellation with a scalpel. RESULTS: This procedure was successfully performed on all patients. Neither laparotomic conversion nor additional port was needed. The mean age and mean BMI of the patients were 43.63 years and 24.02 kg/?. The mean operative time was 148 min and the estimated blood loss in most patients was less than 150 ml. The median weight of uterine corpus was 214 g. No intraoperative complications occurred in any patient. One patient was diagnosed with unexpected endometrioid adenocarcinoma FIGO grade 1 postoperatively. One patient reported cyclic bleeding and underwent a transvaginal trachelectomy 17 months later. CONCLUSION: Single port access LSH using contained manual morcellation represents a safe and feasible alternative to conventional LSH using open power morcellation. PMID- 29458900 TI - Inter-observer variability in fetal biometric measurements. AB - OBJECTIVE: To evaluate inter-observer variability and reproducibility of ultrasound measurements for fetal biometric parameters. MATERIALS AND METHODS: A prospective cohort study was implemented in two tertiary care hospitals in Amman, Jordan; Prince Hamza Hospital and Albashir Hospital. 192 women with a singleton pregnancy at a gestational age of 18-36 weeks were the participants in the study. Transabdominal scans for fetal biometric parameter measurement were performed on study participants from the period of November 2014 to March 2015. Women who agreed to participate in the study were administered two ultrasound scans for head circumference, abdominal circumference and femur length. The correlation coefficient was calculated. Bland-Altman plots were used to analyze the degree of measurement agreement between observers. Limits of agreement +/- 2 SD for the differences in fetal biometry measurements in proportions of the mean of the measurements were derived. Main outcome measures examine the reproducibility of fetal biometric measurements by different observers. RESULTS: High inter-observer inter-class correlation coefficient (ICC) was found for femur length (0.990) and abdominal circumference (0.996) where Bland-Altman plots showed high degrees of agreement. The highest degrees of agreement were noted in the measurement of abdominal circumference followed by head circumference. The lowest degree of agreement was found for femur length measurement. We used a paired-sample t-test and found that the mean difference between duplicate measurements was not significant (P > 0.05). CONCLUSION: Biometric fetal parameter measurements may be reproducible by different operators in the clinical setting with similar results. Fetal head circumference, abdominal circumference and femur length were highly reproducible. Large organized studies are needed to ensure accurate fetal measurements due to the important clinical implications of inaccurate measurements.

AB - : 0BJECTIVE: We compared the diagnostic accuracy of contrast-enhanced computed tomography (CT), fluorine 18-labeled-fludeoxyglucose (18F-FDG) positron emission tomography (PET)/CT and conventional magnetic resonance imaging (MRI) without and with diffusion-weighted imaging (DWI) for characterization of tubo-ovarian abscesses (TOAs) that mimic adnexal tumors. MATERIALS AND METHODS: We evaluated (retrospectively) 43 patients who underwent contrast-enhanced CT, PET/CT, conventional MRI without and with DWI, and who were found to have TOAs and complex adnexal tumors. All images were evaluated independently by four radiologists using a two-point grading system. Results of contrast-enhanced CT, PET/CT, MRI without DWI, and MRI with DWI were compared for each patient using receiver operating characteristic curves. Sensitivity, specificity, and positive predictive value (PPV) were calculated and compared using the chi-square test. RESULTS: Sensitivity of MRI with DWI (95%) was significantly higher than that of contrast-enhanced CT (78.6%), PET/CT (86.7%) and MRI without DWI (87.5%). Specificities of these modalities were not significantly different. The PPV of MRI with DWI (100%) was significantly higher than that of the other three modalities (CT, 72.4%; PET/CT 78.5%; MRI without DWI, 81.5%). Overall accuracy of MRI with DWI was significantly higher than that of the other three modalities (CT, 74.4%; PET/CT, 81.4%; MRI without DWI, 83.7%). CONCLUSION: MRI with DWI shows high accuracy for characterization of complex ovarian lesions, and is the most useful method for differentiation of TOAs from ovarian tumors.

AB - OBJECTIVE: To evaluate whether a maintenance levonorgestrel-releasing intrauterine system is effective for preventing the recurrence of postoperative adenomyosis-related symptoms. MATERIALS AND METHODS: From January 2005 through December 2014, a retrospective study including 133 patients with symptomatic adenomyosis undergoing conservative uterine-sparing surgery followed by gonadotropin-releasing hormone agonist treatment was conducted. We excluded the 18 patients who did not meet the inclusion criteria. The patients of intervention group (n = 54) received a levonorgestrel-releasing intrauterine system (LNG-IUS), which was inserted after surgery. The patients without LNG-IUS insertion were enrolled in the control group (n = 61). The primary outcome was improvement of adenomyosis-related dysmenorrhea, which was evaluated by the visual analog scale (VAS) and by hemoglobin (Hgb) and CA-125 levels. RESULTS: Over a 12-month follow up, the intervention group exhibited a greater reduction in dysmenorrhea as assessed with a VAS score (mean +/- SD: 6.5 +/- 2.5 vs 4.1 +/- 3.6, p = 0.001) and a greater elevation in the Hgb level (2.1 +/- 1.9 vs 1.0 +/- 1.7, p = 0.008) than the control group. At the end of the 24-month follow-up period, the intervention group also exhibited a greater reduction in dysmenorrhea as assessed with a VAS score (mean +/- SD 6.1 +/- 2.7 vs 3.7 +/- 3.7, p = 0.002) and a greater elevation in the Hgb level (1.9 +/- 2.1 vs 0.7 +/- 1.8, p = 0.022) than the control group. The CA-125 level was significantly lower in the intervention group during the postoperative follow up (12th month follow-up, intervention vs control, 24.5 +/- 28.8 vs 50.1 +/- 44.0, p = 0.005; 24th month follow-up, 28.6 +/ 26.2 vs 75.4 +/- 68.5, p = 0.002). CONCLUSION: The maintenance therapy of LNG IUS is effective and well accepted for long-term therapy after conservative surgery for patients with adenomyosis. PMID- 29458903 TI - Day 4 good morula embryo transfer provided compatible live birth rate with day 5 blastocyst embryo in fresh IVF/ET cycles. AB - OBJECTIVE: Embryo transfers during cleavage stage (day 2 or day 3) and blastocyst stages (day 5 or day 6) are common in current daily practice in fresh IVF/ET cycles. Data regarding transferring day 4 embryos, morula/compact stage, is still restricted and the grading system is also inconsistent, as between IVF clinics. This study provided a new detailed classification system for morula/compact stage embryos and compared successes rates between day 4 and day 5 ET. MATERIALS AND METHODS: This was a retrospective study. A review of medical records from January 1st, 2013, to December 31st 2015, performed for all conventional insemination and ICSI cycles with a GnRH-antagonist protocol at the Infertility Division of MacKay Memorial Hospital in Taipei City, Taiwan. RESULTS: There were 427 cycles included in our study, 107 in study group (day 4 MET) and 320 in control group (day 5 BET). Pregnancy rates and live birth rate were compatible, as between morula embryo transfer (MET) and blastocyst embryo transfer (BET). The implantation rate (36.3% vs. 39.6%, respectively, p = 0.500), clinical pregnancy rate (49.5% vs. 51.9%, respectively, p = 0.737), and live birth rate (42.1% vs. 45.6%, respectively, p = 0.574) were statistically insignificant between groups. The term birth rate was statistically higher in the MET group than in the BET group (95.7% vs. 79.5%, respectively, p = 0.006). When the clinical outcomes between day 4 good MET and day 5 good BET were compared, the results were compatible. The implantation rate (48.8% vs. 41.1%, respectively, p = 0.335), clinical pregnancy rate (55.0% vs. 53.2%, respectively, p = 0.867), and live birth rate (47.5% vs. 47.1%, respectively, p = 1.000) showed no significant difference. The term birth rate was also higher in day 4 good MET group than in day 5 good BET group (100% vs. 78.3%, respectively, p = 0.025). CONCLUSION: In this study, we performed day 4 MET avoid BET on Sunday. The grading system we provided was more detailed for embryo selection and it was easier to remember. Our data showed that morula embryo transfer might be a flexible, easier and applicable method for embryo transfer in daily routine. PMID- 29458904 TI - Serum vitamin D concentrations in young Turkish women with primary dysmenorrhea: A randomized controlled study. AB - OBJECTIVE: This study aims to investigate the possible role of vitamin D deficiency in primary dysmenorrhea by assessing serum 25-hydroxyvitamin D3 levels in a cohort which includes young Turkish women with primary dysmenorrhea and healthy controls. MATERIALS AND METHODS: A total of 683 women who were aged between 18 and 25 years and who were consecutively admitted to the study center were eligible. After the exclusion of 55 women, 184 women with primary dysmenorrhea were randomly assigned into the dysmenorrhea group and 184 women without dysmenorrhea were randomly allocated into the control group. RESULTS: The dysmenorrhea group had significantly less consumption of dairy products (p = 0.001), lower serum calcium (p = 0.001), lower serum vitamin D (p = 0.001) and higher serum parathyroid hormone (p = 0.001) than those of the control group. Hyperparathyroidism was significantly less frequent whereas vitamin D deficiency was significantly more frequent in the dysmenorrhea group (p = 0.001 for each). The dysmenorrhea patients with vitamin D deficiency had significantly higher visual analogue scale (VAS) scores (p = 0.001). Depression, irritability, mood swings, fatigue, headache and breast tenderness were significantly more frequent in the vitamin D deficiency group (p < 0.05 for all). The VAS scores of the dysmenorrhea patients correlated positively and significantly with serum parathyroid hormone levels (r = 0.666, p = 0.001) whereas these VAS scores correlated negatively and significantly with serum vitamin D levels (r = -0.713, p = 0.001). DISCUSSION: The significant and positive correlation between vitamin D levels and VAS scores and the significant reduction in serum vitamin D levels of the dysmenorrhea patients designate the possible role of vitamin D deficiency in the primary dysmenorrhea. PMID- 29458905 TI - Obstetric outcomes of twin pregnancies at advanced maternal age: A retrospective study. AB - OBJECTIVE: To evaluate obstetric outcomes in twin pregnancies of advanced maternal age (>=35 years). MATERIALS AND METHODS: A retrospective study involved 470 twin pregnancies in a single center from Sep. 1, 2012 to Mar. 31, 2015. Clinical characteristics and obstetric outcomes were recorded and compared among twin pregnancies who were classified as follows: age 20-29, 30-34, 35-39 and >=40 years. RESULTS: The incidence of gestational diabetes (age 20-29 years 15.8%; 30 34 years 24.3%; 35-39 years 30.4%; >=40 years 57.1%; p = 0.004) and premature delivery (20-29 years 58.6%; 30-34 years 69.1%; 35-39 years 72.2%; >=40 years 85.7%; p = 0.001) significantly increased with increasing age whereas spontaneous abortion (20-29 years 27.6%; 30-34 years 11.6%; 35-39 years 11.4%; >=40 years 0.0%; p = 0.021) decreased in twin pregnancies of advanced maternal age. In addition, the rate of postpartum hemorrhage increased almost continuously by age and advanced maternal age was described as a risk factor for postpartum hemorrhage (age 35-39, adjusted OR 3.377; 95% confidence interval 1729-6.598; p < 0.001; age >= 40, adjusted OR 10.520; 95% CI 1.147-96.492; p = 0.037). However, there was no significant difference between advanced maternal age and adverse neonatal outcomes. CONCLUSION: In twin pregnancies, advanced maternal age experienced significant higher risk of postpartum hemorrhage, gestational diabetes and premature delivery. Neither adverse neonatal outcomes nor stillbirth was significantly associated with maternal age. PMID- 29458906 TI - Comparative cosmetic outcome of surgical incisions created by the PEAK Plasma Blade and a scalpel after cesarean section by Patient and Observer Assessment Scale (POSAS): A randomized double blind study. AB - OBJECTIVE: To compare the cosmetic result of the PEAK Plasma Blade with traditional scalpel in patients who had primary cesarean delivery by using POSAS (Patient and Observer Assessment Scale). MATERIAL AND METHODS: Fourty women between 20 and 40 years, who were planning to have primary cesarean delivery, were randomized for skin incision with PEAK Plasma Blade (n:20) and with scalpel (n:20) were blinded to their group allocation. At six months, the cosmetic outcome of the cesarean scar was assessed using the POSAS. Subjective scar rating was performed using the patient component of the POSAS. Objective scar assessment was performed by an observer dermatologist blinded to the patient's group allocation. RESULTS: The observer scores (p = 0,003), patient scores (p = 0,001) and the total scores (p = 0,001) of the POSAS scale were significantly lower in favor of the Peak Plasma Blade group with respect to the scalpel group. CONCLUSION: The PEAK Plasma Blade has superior cosmetic outcome compared to traditional scalpel skin incision at cesarean section. PMID- 29458907 TI - Surgical and survival outcomes of laparoscopic staging surgery for patients with stage I ovarian cancer. AB - OBJECTIVE: To assess the feasibility and survival outcomes of laparoscopic staging for patients with stage I ovarian cancer. MATERIALS AND METHODS: Consecutive patients who underwent laparoscopic staging surgery for stage I ovarian cancer from January 2002 to December 2014 were evaluated retrospectively by chart review. RESULTS: Twenty-four patients with mean age 43.9 +/- 9.9 years and mean body mass index 24.0 +/- 3.8 kg/m2 were included, in which 12 (50%) patients were in stage IA and 12 (50%) in stage IC. The histological types included serous in 6 (25%), mucinous in 7 (29.1%), endometrioid in 6 (25%), clear cell in 5 (20.8%) patients. The mean surgical time was 306.4 +/- 98.5 min, and the mean blood loss was 204.2 +/- 188.6 mL. None of the patients required conversion to laparotomy. The median numbers of resected pelvic and para-aortic lymph nodes were 20 and 4, respectively. One (4.1%) patient encountered bowel injury intraoperatively, and the other 1 (4.1%) patient hydronephrosis postoperatively. The overall survival rate was 95% in the current series in a median follow-up of 31.5 months. CONCLUSION: Laparoscopic staging surgery performed for early stage ovarian cancer has better long term survival outcomes than the literature report. Laparoscopic treatment by a trained gynecologic oncologist is an ideal alternative for early stage ovarian cancer with the advantage of minimal invasiveness. PMID- 29458908 TI - Is pregnancy associated plasma protein-A (PAPP-A) a marker for adverse perinatal outcomes in preterm isolated oligohydramnios cases? AB - OBJECTIVE: Isolated oligohydramnios is defined as an amniotic fluid index below five centimeter with no other coexisting condition. There are still controversies about the management and pregnancy outcomes. A marker predicting these is crucial. Low pregnancy associated plasma protein-A levels were reported to be related with adverse pregnancy outcomes. We aimed to determine the role of first trimester pregnancy associated plasma protein-A for poor outcomes in preterm isolated oligohydramnios cases. MATERIAL AND METHODS: Fifty-one patients with singleton pregnancies diagnosed as isolated oligohydramnios at 28/0-36/6 weeks of gestation and 110 gestational age matched healthy controls between January and December 2015 were included. Maternal age, gestational age at delivery, mode of delivery, indication for cesarean section, Apgar scores at first and fifth minutes, birth weight, neonatal intensive care unit admission and mortality were recorded. Pregnancy associated plasma protein-A levels were compared between groups and its role in adverse perinatal outcomes was evaluated. RESULTS: Pregnancy associated plasma protein-A levels and pregnancy outcomes were similar in two groups (p > 0.050) except birth weight, gestational age at delivery and presence of fetal distress. Pregnancy associated plasma protein-A levels did not differ in terms of delivery mode, presence of fetal distress, first and fifth minutes Apgar scores and neonatal intensive care unit admission (p = 0.323,0.650,0.990,0.112,0.853). Also, it was not determined as a risk factor for cesarean section, presence of fetal distress, low Apgar scores and neonatal intensive care unit admission. CONCLUSION: Pregnancy associated plasma protein-A, a well-known prognostic factor for some of high risk pregnancy conditions, may not be used as a marker in preterm isolated oligohydramnios cases. PMID- 29458909 TI - Effect of morphokinetics and morphological dynamics of cleavage stage on embryo developmental potential: A time-lapse study. AB - OBJECTIVE: Using a non-invasive method to select the most competent embryo is essential in in vitro fertilization (IVF). Since the beginning of clinical application of time-lapse technology, several studies have proposed models using the time-lapse imaging system for predicting the IVF outcome. This study used both morphokinetic and morphological dynamic parameters to select embryos with the highest developmental potential. MATERIALS AND METHODS: A total of 23 intracytoplasmic sperm injection treatment cycles with 138 fertilized oocytes were included in this study. All embryos were cultured to the blastocyst stage, and embryo development was recorded every 10 min by using a time-lapse imaging system. Morphokinetic parameters and eight major abnormal division behaviors were studied to determine their effects on blastocyst formation. The most influential variables were used in hierarchical classification for blastocyst formation prediction. RESULTS: Several parameters were significantly related to the developmental potential. Embryos with the timing of pronuclear fading (tPNF) of >26.4 h post insemination (hpi), the timing of division to two cells (t2) of >29.1 hpi, and the timing of division to four cells (t4) of >41.3 hpi showed the lowest blastocyst formation rate. The abnormal division behaviors of fragmentation >50%, direct cleavage, reverse cleavage, and delayed division or developmental arrest were found to be detrimental to blastocyst formation. On the basis of these results, we propose a hierarchical model classification, in which embryos are classified into groups A-D according to their developmental potential. The blastocyst formation rates of groups A, B, C, and D were 80.0%, 77.8%, 53.7%, and 22.2% (p < 0.001). The good blastocyst rates of groups A, B, C, and D were 60.0%, 44.4%, 14.6%, and 11.1% (p = 0.007). CONCLUSION: We propose a hierarchical classification system for blastocyst formation prediction, which provides information for embryo selection by using a time-lapse imaging system. PMID- 29458910 TI - Maternal characteristics and pregnancy outcomes among illicit drug-using women in an urban setting. AB - OBJECTIVE: To identify characteristics and pregnancy outcomes among pregnant illicit drug users living in an urban area, and to describe trends in drug use over an 8-year period. MATERIALS AND METHODS: Data on pregnant women living in the Bangkok Metropolitan Region who delivered at our institution during 2008-2015 were studied. Women with drug use (n = 197) and women without drug use (n = 787) were compared in terms of maternal characteristics and pregnancy outcomes. RESULTS: The pregnant drug user rate markedly rose from 0.46% in 2008 to 1.28% in 2015. All pregnant drug users consumed amphetamine-type stimulants (ATS). The most important factor related to drug use was smoking (adjusted odds ratio [aOR] 41.03, 95% confidence interval [CI] 18.90-89.04). Other significant characteristics were teenage pregnancy (aOR 1.78, 95% CI 1.01-3.18), low level of education (aOR 4.97, 95% CI 1.18-20.90 for secondary school and aOR 5.61, 95% CI 1.28-24.49 for primary school or lower), and inadequate number of antenatal visits (aOR 2.20, 95% CI 1.16-4.17 for 1-3 visits and aOR 14.05, 95% CI 7.54 26.16 for no visit). Women of non-Thai ethnicity were less likely to use drugs (aOR 0.15, 95% CI 0.04-0.54). Pregnant drug users had a significantly higher risk of anemia (aOR 1.73, 95% CI 1.05-2.85), preterm delivery (aOR 2.35, 95% CI 1.29 4.29), low birth weight (aOR 2.26, 95% CI 1.23-4.17) and small for gestational age infants (aOR 3.19, 95% CI 1.39-7.33), but lower risk of cesarean section (aOR 0.43, 95% CI 0.21-0.86) than non-drug users. CONCLUSION: Compared to urban pregnant women without drug use, women who consumed drugs were younger, had lower level of education, poorer self-care and poorer pregnancy outcomes. ATS was the single most commonly used drug. PMID- 29458911 TI - Pharmacogenetic study of pruritus induced by epidural morphine for post cesarean section analgesia. AB - OBJECTIVE: The mechanism through which neuroaxial morphine causes pruritus has not been elucidated clearly and thoroughly. MATERIALS AND METHODS: a study in 129 female parturients was conducted to investigate the effect of 14 single nucleotide polymorphisms (SNPs) on phenotype (pruritus) induced by neuroaxial (including intrathecal or epidural) morphine for cesarean section. Clinical phenotype, subjective complaints and objective observations were recorded. DNA from blood samples was used to record the SNPs. Eleven SNPs were then analyzed further. RESULTS: no significant association with the presence of phenotype (pruritus) versus genotype was observed (all p-values > 0.05). No significant association with severity of phenotype versus genotype of the 11 SNPs was observed except for unadjusted data for rs2737703. There was no significant difference between severity or incidence of IVPCA morphine-induced nausea and vomiting and genotype (11 SNPs). CONCLUSION: our results showed no association between SNPs of any of the genes studied with neuroaxial morphine inducing pruritus. PMID- 29458912 TI - Early fetal reduction to twin versus prophylactic cervical cerclage for triplet pregnancies conceived with assisted reproductive techniques. AB - OBJECTIVE: To compare the obstetric outcomes of triplet gestations managed by early fetal reduction to twins with those managed by prophylactic cervical cerclage in women conceived with assisted reproductive techniques (ART). MATERIALS AND METHODS: Retrospective study of the pregnancy and neonatal outcomes of trichorionic triplet gestations achieved by ART and managed either by early transvaginal fetal reduction to twins (n = 53) or by prophylactic placement of cervical cerclage (n = 65). RESULTS: The pregnancy duration was significantly longer with fetal reduction and the incidences of delivery before 34 and 32 weeks gestational age were significantly lower with fetal reduction. Both miscarriage and live birth rates were comparable in the two groups. The incidences of very low birth weight (VLBW), neonatal respiratory distress syndrome (RDS), admission to neonatal intensive care unit (NICU) and early neonatal death (END) were significantly lower with fetal reduction. CONCLUSION: Early transvaginal reduction of triplets to twins leads to improved obstetric outcomes as it decreases prematurity and its related neonatal morbidities and mortality without increase in the miscarriage rate. Early fetal reduction seems to be better than continuation of triplet pregnancies with prophylactic placement of cervical cerclage. PMID- 29458913 TI - Use of complementary approaches in pregnant women with a history of miscarriage. AB - OBJECTIVES: To describe the use of complementary approaches in pregnant women with a history of miscarriage and to investigate whether a miscarriage is associated with the use of complementary approaches during their pregnancy. DESIGN: A cross-sectional survey was distributed to pregnant women residing in the United States (N=890). RESULTS: Women who had a history of miscarriage, were Caucasian, were college educated, reported a high income, had low depression scores, and had low anxiety scores (all P<0.001) were more likely to use complementary approaches. In pregnant women with a history of miscarriage (N=193), the most frequently reported complementary approaches used were prayer (22.3%), yoga (15%), massage (14.5%), chiropractic (13%), and meditation (11.4%). Finally, after adjustment for age, race, education, and income, the odds of using a complementary approach in women with a history of miscarriage was 1.8 (95% CI: 1.3, 2.5, P<0.001) as compared with women without a history of miscarriage (model 1). Associations persisted after additional adjustment for depression, anxiety, and stress; the odds of using a complementary approach in women with a history of miscarriage was 1.7 (95% CI: 1.2, 2.4, P<0.001) (model 2), compared with women without a history of miscarriage. CONCLUSIONS: Findings from this study may help inform future studies for pregnant women with a history of miscarriage and may also provide information about appropriate strategies in which health care providers can refer their patients. PMID- 29458914 TI - Associations between complementary medicine, satisfaction with body weight and shape, and the use of methods to lose or control weight: Results of a national survey of 8009 Australian women. AB - OBJECTIVE: This study aimed to determine whether the use of complementary medicine (CM) is associated with body satisfaction and weight management methods in Australian women. METHODS: Women aged 34-39 years from the Australian Longitudinal Study on Women's Health were surveyed regarding satisfaction with their body weight and shape, and the use of weight management methods. Associations with CM use were analysed using logistic regression modelling. RESULTS: Women using CM less likely wanted to lose weight; and were more likely to cut down on fats and/or sugars, use low glycaemic diets, diet books and 'other' methods (OR: 1.33-2.83) compared to CM non-users. Women using herbal medicine products 'sometimes' were more likely to use meal replacements/slimming products (OR: 1.50-1.67) compared to non-users. DISCUSSION: Australian women using CM are more likely to be satisfied with their body weight and shape, and to use a range of weight management approaches compared to CM non-users. PMID- 29458915 TI - The effects of reflexology on anxiety and pain in patients after abdominal hysterectomy: A randomised controlled trial. AB - OBJECTIVES: This study aimed at finding out the effects of reflexology on pain, anxiety levels after abdominal hysterectomy. DESING & METHODS: The study was performed on women hospitalized in the intensive care unit and gynecology services of Ege University Hospital in Izmir after abdominal hysterectomy between September 2013 and September 2014. This study was designed and conducted as a randomized controlled trial. The study sample consisted of 63 female patients: 32 in the experimental group and 31 in the control group. The postoperative daily monitoring sheet, Spielberger State Anxiety Inventory (SAI), was employed to collect research data and "visual analog scale" to evaluate pain levels. RESULTS: The female patients' average age was found to be 47.23 +/- 4.71. The three-day monitoring showed a significant difference between the experimental and control groups in terms of average pain levels and anxiety scores after reflexology (p < 0.05). CONCLUSION: Foot reflexology may serve as an effective nursing intervention to increase the well-being and decrease the pain of female patients after abdominal hysterectomy, and nurses should be aware of the benefits of reflexology. PMID- 29458916 TI - Use of complementary and alternative medicine in patients with multiple sclerosis in Germany. AB - BACKGROUND: The use of complementary and alternative medicine (CAM) for chronic diseases such as multiple sclerosis (MS) is becoming an increasingly important issue for those affected. Especially in Germany there are only a few studies dealing with CAM, as yet. The aim of this study was to assess the prevalence, the methods used, the subjective benefits as well as physician/patient communication. METHODS: A structured questionnaire including demographic and disease-specific data, CAM use, perceived benefits as well as physician/patient communication was sent to real and web-based self-help groups for MS in Germany. RESULTS: 343 answers could be evaluated. 77.3% of the participants were females. The mean age was 45.0 +/- 11.9 years and the duration of the disease was 12.0 +/- 9.6 years. 81.9% said they were using CAM, nearly half (44.8%) used it alternatively to conventional medicine. The average number of CAM- methods used were 3.6. The most popular methods were vitamin supplements, Yoga/Thai chi/Qi Gong, relaxation techniques and meditation. Approximately half (139/49.5%) of CAM users disclosed this to their treating neurologist. Yet, 37,6% have doubts on the competence of the respective physician. CONCLUSION: Patients with MS have a strong interest in CAM. Usage as alternative therapy is widespread and puts patients at risk of progress of the disease. As patient/physician communication on the topic is increasing, neurologists should be attentive to guiding their patients through safe complementary methods. PMID- 29458917 TI - Chinese herbal medicine to treat urolithiasis in a patient with right flank pain and hematuria: A case report. AB - OBJECTIVE: Urolithiasis is a common medical condition affecting the urinary tract. Typical symptoms reported by patients include colic pain and hematuria. Some patients may undergo surgical intervention or lithotripsy to remove the stones. In this case, we demonstrated that Chinese herbal medicine (CHM) was an effective modality to remove stones in a patient with urolithiasis. CLINICAL FEATURES AND OUTCOME: A 47-year-old man suffered from right flank pain and hematuria for three months and was diagnosed with an upper third ureteral stone obstruction with right hydronephrosis. He had received extracorporeal shock wave lithotripsy (ESWL) three times before his first CHM visit, but it was unsuccessful. Therefore, he sought CHM for further intervention. His symptoms subsided, and the image study showed complete removal of the ureteral stone after regular therapy with Zhi Bai Di Huang Wan () combined with Lygodii spora (), Curcumae radix (), Endothelium Corneum Gigeriae Galli (), Lysimachiae herba (), Orthosiphon stamineus () for approximately four months. Neither complications nor side-effects were noted during the CHM treatment. CONCLUSIONS: In this case, we concluded that CHM may be an effective alternative therapy for the treatment of ureteral stones, and furthermore, may also be applied as an option to salvage failed ESWL procedures. PMID- 29458918 TI - Management of IFN-beta-induced flu-like symptoms with Chinese herbal medicine in a patient with multiple sclerosis: A case report. AB - OBJECTIVE: The purpose of this case report was to elucidate how Chinese herbal medicine (CHM) was used safely in this patient undergoing interferon beta (IFNbeta-1a) treatment and was associated with reduction in the side effects the patient had experienced when using IFNbeta-1a treatment alone. CLINICAL FEATURES AND OUTCOME: A 30-year-old man was diagnosed with MS in December 2014. For two years, he suffered from severe flu-like symptoms as side effects of IFNbeta-1a treatment. He subsequently received treatment with Chinese herbal medicine. During a two-month period of treatment with CHM, the patient responded well, with most of the symptoms induced by IFNbeta-1a ameliorated. The fever subsided. Incidence rates of dizziness and headaches were reduced. The health condition compared to the prior year increased by 50%. According to CCMQ and SF-36 assessments, CHM had the beneficial effects of recovering the yin-yang balance, harmonizing the qi, and regulating the blood state; essentially, improving the patient's comfort level and quality of life. CONCLUSIONS: IFNbeta-1a injections will damage qi and cause blood stasis in MS patients, thereby causing various side effects and weakening the body's immune system. Bu-Zhong-Yi-Qi-Tang, associated with Salvia miltiorrhiza, Ligusticum chuanxiong, Angelica dahurica and Polygonum multiflorum Thunb., is an effective prescription to ameliorate such symptoms and signs in patients with MS. PMID- 29458919 TI - Yoga meditation (YoMed) and its effect on proprioception and balance function in elders who have fallen: A randomized control study. AB - OBJECTIVE: Yoga has been shown to improve muscle strength, flexibility, and balance. However, the impact of meditation on dynamic factors such as gait, reactive balance and proprioception has yet to be examined. The purpose of this study was to test if a novel yoga meditation program (YoMed) is as effective as a standard proprioceptive training in improving proprioception, balance and power in older individuals who have fallen. DESIGN: Sixteen older persons were randomly assigned to either the YoMed Group (YM) or Proprioception Training Group (PT). Each group received 45 min of training, 3 days per week, for 6 weeks. Pretest and post-test outcome measures were used to quantify the comparative effects of the interventions. SETTING: Research Laboratory. INTERVENTIONS: Yoga meditation and proprioceptive training. MAIN OUTCOME MEASURES: The Balance Error Scoring System (BESS), the Tenetti Balance and Gait Assessment, dynamic posturography, joint position sense, joint kinesthesia and leg extensor power. RESULTS: The primary findings of the study were that neither the YM or PT intervention groups showed statistical improvements in any variable with the exception of the dynamic posturography overall score (DMA), which showed a significant improvement by the YM group (d = 1.238; p = 0.049). Additionally changes in a number of variables that did not reach significance demonstrated effect sizes in the medium to high range. CONCLUSION: These results indicate the potential for the YoMed program to be used as a clinical intervention in older individuals. Given these results a longer study using a larger sample size and individuals at higher risk of falling is warranted. PMID- 29458920 TI - Interest in online interprofessional elective mind-body skills (MBS) training. AB - INTRODUCTION: There is growing interest in mind-body skills (MBS) education and online interprofessional elective MBS training for health professionals. We conducted this study to understand a) the demand among different health professionals for an online MBS course; b) engagement with different MBS topics; and c) planned behavior changes. METHODS: We examined registrations from May 1 through August 31, 2014 for a new online MBS elective, analyzing the percentage of registrants who engaged with one or more of 12 modules by September 30, 2014. We also reviewed written comments about planned behavior change. RESULTS: The 693 registrants included physicians, nurses, social workers, dietitians, psychologists, and others. The two most popular topics were "Introduction: to Stress, Resilience, and Relaxation Response" and "Autogenic Training". Half of registrants (57%) engaged with at least one module and 9% completed all 12 modules within the study period. Nearly all (90%) of those who completed evaluations planned to use the technique they learned for themselves, introduce it to patients, or both. DISCUSSION: Online elective MBS training attracts diverse health professionals and leads to plans for personal and professional behavior change. Additional research is necessary to understand the impact of different amounts and kinds of MBS training on professionals' resilience, burnout, and quality of care.

AB - OBJECTIVES: This study aims to investigate the metabolic profiles of postoperative colorectal cancer (PCRC) patients with different traditional Chinese medicine (TCM) syndromes and to discuss the metabolic mechanism under PCRC progression and TCM syndrome classification. METHODS: Fifty healthy controls (HC) and 70 PCRC patients, including 10 Dampness and heat syndrome (DHS), 33 Spleen deficiency syndrome (SDS), 19 Liver and kidney Yin deficiency syndrome (LKYDS) and 8 with non-TCM syndrome (NS) were enrolled. Plasma metabolic profiles were detected by Gas chromatography-mass spectrometry (GC-MS) and analyzed by principal component analysis (PCA) and partial least squares-discriminate analysis (PLS-DA). Furthermore, pathway enrichment was analyzed based on KEGG and DAVID databases and metabolic network was constructed via metaboanalyst and cytoscape. RESULTS: The top-3 metabolites with higher abundance in PCRC compared with HC were terephthalic acid (165.417-fold), ornithine (24.484-fold) and aminomalonic acid (21.346-fold). And the cholesterol (0.588-fold) level was decreased in PCRC. l-Alanine, 1, 2-ethanediamine, urea, glycerol, glycine, aminomalonic acid, creatinine and palmitic acid were specifically altered in the DHS, while d-tryptophan was exclusively changed in SDS, and l-proline, 1, 2, 3 propanetricarboxylic acid, d-galactose and 2-indolecarboxylic acids in LKYDS. CONCLUSIONS: The plasma metabolic profiles were perturbed in PCRC patients. Increased levels of terephthalic acid might indicate high risk of relapse and elevated ornithine may contribute to the post-operational recovery or may raise the susceptibility to PCRC recurrence. The metabolic profiles of DHS, SDS, LKYDS and NS were almost separately clustered, indicating the possibility of explaining TCM syndromes classification using metabolomics. Furthermore, creatinine and aminomalonic acid alternation might correlate with the formation of DHS, while d tryptophan may associate with SDS and d-galactose and 1, 2, 3 propanetricarboxylic acid may relate to LKYDS. As numbers of patients in each TCM syndrome are small, further study is needed to verify those results. PMID- 29458922 TI - Massage therapy for home care patients using the health insurance system in Japan. AB - OBJECTIVES: To clarify the status of home care massage services provided to patients. This will help in understanding how many patients utilize this service and the circumstances under which treatment is provided. DESIGN: A retrospective study. SETTING: Fifty-four acupuncture, moxibustion, and massage clinics. Participants were patients who had received home care massage for six months or more. We collected a total of 1587 responses from these 54 massage clinics; of these, 1415 responses (mean age = 79.1 +/- 11.5 years) were valid (valid response rate 89.2%). MAIN OUTCOME MEASURES: Actual patients and actual care services. RESULTS: The most common disorder observed among patients who utilized home care massage services was cerebrovascular disease (at approximately 36%), while the second most common were arthropathy-related disorders (16.3%). Although most patients received massage, approximately 30% received manual therapy (e.g. manual correction) and hot fomentation as part of thermotherapy. Notably, only around 10% of patients received massage alone; the majority received treatment in combination with range of motion and muscle-strengthening exercises. CONCLUSIONS: This study helped to clarify the actual state of patients receiving home care massage and the details of the massage services provided. This study clearly showed the treatment effectiveness of massage, which can be used by home medical care stakeholders to develop more effective interventions. PMID- 29458923 TI - A bicentric controlled study on the effects of aquatic Ai Chi in Parkinson disease. AB - OBJECTIVES: Various exercise strategies have been suggested to address movement deficits in order to improve motor function and quality of life for individuals in the early or moderate stages of Parkinson disease. The purpose is to evaluate the effects of an aquatic Ai Chi intervention on balance, gait speed and quality of life of patients. DESIGN AND INTERVENTION: Twenty-nine people with Parkinson disease participated in this pilot study. People were randomized into (1) aquatic Ai Chi program (experimental group) and (2) a dry land conventional Western physical therapy intervention (control group). Twenty-two twice-weekly sessions were performed with the 14 patients assigned to the experimental group, during the same period of time as the control group (same number of sessions), who received dry land therapy. MAIN OUTCOMES MEASURES: Visual Analogue scale (VAS), The Timed Get up and Go test, Five Times Sit-to-Stand test, single leg standing, Yesavage test and Parkinson's Disease Questionnaire (PDQ-39). A descriptive analysis was performed on all study variables. RESULTS: The results showed a significant effect on time - of a high effect which indicates that the VAS scores (F 1.3; p < 0.001), Five time (F = 1.8; p = 0.001) and Get up and Go (F = 1.7; p < 0.001) significantly decreased in time, independent of the treatment group. In contrast, no significant differences were found in the results shown on the PDQ 39 scale, finding only changes in the section of social support (p < 0.001 F = 18.63). CONCLUSIONS: The results of this 11-week controlled pilot trial suggest that aquatic Ai Chi applied twice weekly may potentially reduce Parkinsonian symptoms as measured on different motor symptoms, bradykinesia and rigidity. PMID- 29458924 TI - Effect of olfactory stimulation with essential oils on cardiovascular reactivity during the moving beans task in stroke patients with anxiety. AB - OBJECTIVE: To investigate the effect of olfactory stimulation with essential oils on cardiovascular reactivity during the "moving beans" rehabilitation task in stroke patients with anxiety. METHODS: Twenty-eight stroke patients participated in this study. Blood pressure and heart rate were measured before and after finger movement tasks (e.g., moving beans and the Purdue pegboard test). Olfactory stimulation with lavender oil, grapefruit oil, and distilled water were conducted during finger tasks. Anxiety was assessed using the State Trait Anxiety Inventory (STAI)-Y2 before the finger movement tasks. RESULTS: There were no significant changes in blood pressure or heart rate activity in both finger movement tasks when stimulation of lavender oil, grapefruit oil, and distilled water was applied. However, the change values of Delta diastolic blood pressure (DBP) associated with the moving beans task indicated a significant interaction between olfactory stimulations and the groups of STAI-Y2 scores (high vs low) (p=0.03), without main effects in the olfactory stimulations and the groups of STAI-Y2 scores. CONCLUSION: Olfactory stimulation with lavender and grapefruit oil may repress the exaggerated DBP response during the moving beans task in stroke patients with higher levels of trait anxiety symptoms. PMID- 29458925 TI - Is cupping blister harmful?-A proteomical analysis of blister fluid induced by cupping therapy and scald. AB - OBJECTIVE: Cupping therapy has a long history in traditional medicine especially in Asian countries. It was controversial whether cupping induced blisters are beneficial to healing effects, and the formation and content in the blisters remain unexplored. We aimed to identify and compare the molecular components of the blister fluid from the cupping therapy and the scalds to explore the necessary of inducing cupping induced blisters. METHODS: Fluid sample of blisters from fifteen patients receiving cupping therapy (Cupping group) and scald burns (Scald group) were collected in this study. Proteins from the blisters were separated by two-dimensional electrophoresis (2D-gel) and further analyzed by mass spectrometry. In addition, the changes in particular proteins were confirmed by Western blotting. RESULTS: The protein components are significantly different between blister from cupping therapy and scalds. The immune responses, oxidative stress and metabolic related proteins (Ig lambda-2 chain C regions, Ig gamma-1 chain C region, hemopexin, prdx2, calmodulin, succinyl-CoA ligase and tetranectin) were increased, whereas the hemoglobin subunit beta was decreased in the Cupping group compared with the Scald group. CONCLUSIONS: Cupping induced blisters contain several proteins which relate to the activation of certain immune pathways including anti-oxidation, anti-apoptosis, tissue repairing and metabolic regulation. This proteomic analysis may indicate a significant clue to the mechanism study of cupping. PMID- 29458926 TI - Pregnancy outcomes in psychiatric patients treated with passiflora incarnata. AB - Passiflora incarnata is marketed in many countries as anxiolytic herbal supplement. Herbal medicines are natural products, but it doesn't mean they are always safe, especially during pregnancy. Passiflora incarnata extract was not teratogenic in experimental studies. However, there are no data available on possible effects on human pregnancy. Here we report five pregnant women with depression and/or anxiety who used passiflora incarnata in pregnancy. We observed one pregnancy resulting in neonatal death, two pregnancies with premature rupture of membranes, two infants with meconium aspiration syndrome and one infant with persistent pulmonary hypertension. No birth defects and no growth or developmental abnormalities for the live born infants were reported at 6 months of age. This observation is important since there have been no human reports about the use of passiflora incarnata in pregnant women. Pregnant women exposed to passiflora incarnata should be monitored, unless further data are available. PMID- 29458927 TI - The effect of pleasant olfactory mental imagery on the incidence and extent of atelectasis in patients after open heart surgery. AB - BACKGROUND AND PURPOSE: Atelectasis is the most common pulmonary complication after open heart surgery. This study was intended to examine the effects of pleasant olfactory mental imagery on postoperative atelectasis in patients undergoing open heart surgery. MATERIALS AND METHODS: This is a randomized controlled clinical trial. The sample consisted of 80 patients who were randomly assigned to either practice olfactory mental imagery (test group) or receive routine care (control group). A card with the image of roses was given to patients and they were asked to look at the image, visualize the scent of roses in the mind, and then sniff as much as possible, hold their breath for 2s and eventually exhale slowly through the nose. This procedure was consecutively repeated five times. After a fifteen-minute break, patients proceeded to practice olfactory mental imagery with other fruit images (banana, apple, and lemon). The test group executed the olfactory mental imagery for two hours in the morning and two hours in the afternoon on postoperative days 1 and 2. The control group received the routine ICU care. A questionnaire collected information on sociodemographic characteristics and clinical parameters. Chest radiographs were used to diagnose atelectasis, which were evaluated by the hospital radiologist. RESULTS: No statistically significant differences were observed between the two groups regarding sociodemographic, medical and surgical information. The incidence of atelectasis in the test group (40%, n=16) was significantly lower than in the control group (67.5%, n=27) on postoperative day 2 (p=0.02). CONCLUSION: Our findings suggest that olfactory mental imagery can improve respiratory function and reduce the risk of atelectasis in patients with cardiac surgery. PMID- 29458928 TI - Adjunctive Vitamin D in the treatment of non-remitted depression: Lessons from a failed clinical trial. AB - BACKGROUND: Many patients with depression fail to achieve remission after several consecutive treatments. Vitamin D deficiency is prevalent and new research suggests that it may have an impact on mood, primarily through an effect on neurotransmitters. Numerous observational studies suggest a relationship between low levels of vitamin D and increased incidence and severity of mood disorders. A small number of pilot studies have been undertaken but lack rigorous methodology required to draw conclusions about a clinical role for this nutrient in treatment resistant depression. METHODS: This study was designed as a randomized, double blind, placebo controlled intervention study administering a weekly (bolus) dose of 28 000IU of Vitamin D3 or placebo to 125 patients with non-remitted depression adjunct to current antidepressant medication. Patients were followed weekly for eight weeks plus a one month follow up. Outcomes measured included depression severity, serum vitamin D levels and safety. Due to slow recruitment during the first season, amendments were made. These included extending the age range to 18 75 and removing the requirement for failing to respond to one pharmacologic antidepressant agent. The protocol was amended to reduce the burden on participants by changing the in-office visits to bi-weekly. Three additional tertiary psychiatric clinics were also added as trial sites. RESULTS: Over three recruitment period years (fall/winter), a total of 148 participants completed screening, 24 (16.2%) of whom qualified to participate in the study. Use of too many or no psychiatric medications, comorbid exclusionary psychiatric conditions, current use of a vitamin D supplement, and lack of participant compensation were the predominant reasons for ineligibility or unwillingness to participate. 9 participants were successfully enrolled in the study, 7 (77.8%) of whom completed the trial as per the protocol. After the third season, futility was declared based on inability to enroll participants. The sample size of enrolled participants (7/125, 5.6%) lacks power to conduct a full assessment of findings. DISCUSSION: High accessibility of vitamin D, as well as a growing lack of equipoise in patients and clinicians about the potential ubiquitous benefits of vitamin D for Canadians, not just for mood disorders, resulted in a large proportion of ineligible potential participants. Limited funding provided to studies on natural health products hampered recruitment. The labile and fluctuating nature of non-remitted depression as well as frequent co-morbid conditions creates additional challenges for conducting trials in this population. Future studies assessing vitamin D in depression should consider our experiences in design and conduct of research. Innovations in clinical trial design such as preference trials or accepting patients already using vitamin D but not achieving an optimal target value are potential solutions to some of these challenges. PMID- 29458929 TI - Physical activity is associated with higher cognitive function among adults at risk for Alzheimer's disease. AB - OBJECTIVE: We evaluated the specific association between physical activity and cognitive function among a national sample of the broader U.S. adult population with a family history of Alzheimer's disease. METHODS: Data from the 1999-2002 National Health and Nutrition Examination Survey (NHANES) were used to identify 219 older adults, ages 60-85, with a family history of Alzheimer's disease. The Digit Symbol Substitution Test (DSST) was used to assess cognitive function, with physical activity assessed via a validated questionnaire. RESULTS: In an unadjusted model, older adults, who had at least one blood relative with Alzheimer's disease, had greater cognitive function when meeting MVPA guidelines in comparison to their inactive counterparts (beta=9.6; 95% CI: 4.6-14.7; P=0.001). After adjustments, results were attenuated, but still statistically significant (8.5; 95% CI: 4.0-13.0; P=0.001). CONCLUSION: In this national sample of individuals at risk for Alzheimer's disease, meeting physical activity guidelines was associated with higher cognitive function. PMID- 29458930 TI - Veterans in substance abuse treatment program self-initiate box gardening as a stress reducing therapeutic modality. AB - OBJECTIVES: To assess the experiences of a veteran initiated horticultural therapy garden during their 28-day inpatient Substance Abuse Residential Rehabilitation Treatment Program (SARRTP). DESIGN: Retrospective study. SETTING: Veterans Affairs Medical Center (VAMC), Salem, Virginia, USA INTERVENTIONS: Group interviews with veterans from the last SARRTP classes and individual interviews with VAMC greenhouse staff in summer of 2016. OUTCOME MEASURES: Time spent in garden, frequency of garden visits, types of passive and active garden activities, words describing the veterans' emotional reactions to utilizing the garden. RESULTS: In 3 summer months of 2016, 50 percent of the 56 veterans interviewed visited and interacted with the gardens during their free time. Frequency of visits generally varied from 3 times weekly to 1-2 times a day. Amount of time in the garden varied from 10min to 2h. The veterans engaged in active and/or passive gardening activities during their garden visits. The veterans reported feeling "calm", "serene", and "refreshed" during garden visitation and after leaving the garden. CONCLUSIONS: Although data was secured only at the end of the 2016 growing season, interviews of the inpatient veterans revealed that they used their own initiative and resources to continue the horticulture therapy program for 2 successive growing years after the original pilot project ended in 2014. These non-interventionist, therapeutic garden projects suggest the role of autonomy and patient initiative in recovery programs for veterans attending VAMC treatment programs and they also suggest the value of horticulture therapy as a meaningful evidence- based therapeutic modality for veterans. PMID- 29458931 TI - Assessment of the psychopathological effects of a horticultural therapy program in patients with schizophrenia. AB - OBJECTIVES: This study assessed the psychopathological effects of participation in a 10-session horticultural therapy program in patients with schizophrenia. DESIGN: The study design was pre and post test design of experimental and control groups. SETTING: Twenty-eight Korean patients with schizophrenia, recruited from a mental health clinic and two mental health rehabilitation centers in Suwon, South Korea, were voluntarily assigned to either a control group (average age: 33.4+/-9.4years) or a horticultural therapy group (average age: 42.1+/ 13.0years). INTERVENTIONS: The participants in the horticultural therapy group participated in a 10-session horticultural therapy program designed around various plant cultivating activities. The horticultural therapy program involved sessions once a week from April 2017 to June 2017. MAIN OUTCOME MEASURES: A psychiatrist evaluated the psychopathological symptoms of schizophrenic patients in both groups. To assess the clinical psychopathological effects, the Korean version of the Positive and Negative Syndrome Scale (PANSS) and Brief Psychiatric Rating Scale (BPRS) were used. RESULTS: The horticultural therapy group significantly improved in terms of positive, negative, and general symptoms on the PANSS after the 10-session horticultural therapy program. Moreover, the horticultural therapy group significantly improved in terms of clinical symptoms of schizophrenia in BPRS after the 10-session horticultural therapy program. However, there was no change in the PANSS and BPRS scores in the control group. CONCLUSIONS: This study showed the potential of horticultural therapy in improving psychopathological symptoms in psychiatric patients. Future studies should investigate the effects of long-term horticultural therapy program on the chronic symptoms of patients with schizophrenia. PMID- 29458932 TI - Efficacy of Arsenicum album 30cH in preventing febrile episodes following DPT HepB-Polio vaccination - a randomized, double-blind, placebo-controlled clinical trial. AB - BACKGROUND: Among the post-immunization adverse events, especially of Diphtheria Pertusis-Tetanus (DPT), fever is a common systemic reaction. There is anecdotal support for the use of the homeopathic medicine Arsenicum album in preventing post-vaccination fever. The investigators intended to evaluate its efficacy in preventing febrile episodes following vaccination. METHODS: In the community medicine out-patient of Mahesh Bhattacharyya Homoeopathic Medical College and Hospital, West Bengal, India, between August 2014 and January 2017, a double blind, randomized, placebo-controlled trial was conducted on 120 children (verum: 60, placebo: 60) who presented for the 2nd and 3rd dose of DPT-HepB-Polio vaccination and reported febrile episodes following the 1st dose. Intervention used was Arsenicum album 30cH 6 doses or placebo (indistinguishable from verum), thrice daily for two subsequent days. Parents were advised to report any event of febrile attacks within 48h of vaccination, either directly or over telephone. RESULTS: The groups were comparable at baseline. Children reporting fever after the 2nd dose was 29.8% and 30.4% respectively for the homeopathy group and control group respectively [Relative Risk (RR)=1.008] with no significant difference (P=0.951) between groups. Again after the 3rd dose, children reporting fever were 31.5% and 28.3% respectively for the homeopathy group and control group respectively (RR=0.956) with no significant difference (P=0.719) between groups. CONCLUSION: Empirically selected Arsenicum album 30cH could not produce differentiable effect from placebo in preventing febrile episodes following DPT HepB-Polio vaccination.

PMID- 29458933 TI - Effect of whole body cryotherapy interventions on health-related quality of life in fibromyalgia patients: A randomized controlled trial. AB - INTRODUCTION: Although fibromyalgia syndrome (SFM) affects 2-4 percent of adults, research has not identified a preferred therapeutic option for patients worldwide yet. Based on recent findings, it can be expected that whole body cryotherapy can improve health-reported quality of life by alleviating the symptoms of musculoskeletal pain and fatigue. OBJECTIVE: Our aim was to determine whether whole body cryotherapy only can result in improved perceived health and quality of life in fibromyalgia patients. METHODS: 24 patients with fibromyalgia diagnosis were randomized into 2 groups (n=11 in the whole body cryotherapy group, n=13 in the control group). In the whole body cryotherapy group, 10 sessions of whole body cryotherapy were performed (in addition to usual care) in a standard cryotherapy room over a duration of 8days. Subjects in the control group did not change anything in their everyday activities. Quality of life was assessed just before and one month after treatment. RESULTS: Compared with the control group, patients in the whole body cryotherapy group reported significantly improved for health-reported quality of life. These effects lasted for at least one month following intervention. CONCLUSION: Based on these findings, whole body cryotherapy can be recommended as an effective clinically adjuvant approach in the improvement of health-related quality of life in fibromyalgia patients. PMID- 29458934 TI - Effect of aromatherapy on coping with premenstrual syndrome: A randomized controlled trial. AB - BACKGROUND AND AIM: Premenstrual Syndrome (PMS) is a health problem which begins approximately one week before menstruation in women occurs as a set of physical and psychological symptoms. This study aimed to determine the effect of aromatherapy on coping with premenstrual syndrome in university students. METHODS: A randomized controlled trial design was used. This study included 40 students in the intervention and 37 students in the control groups. Data was collected by questionnaire form and PMS scale. The intervention and control groups were followed up for 3 cycles in terms of PMS symptoms. The method of inhalation aromatherapy by lavender oil was applied for 5 sessions on average for each cycle. RESULTS: When PMS mean scores of the intervention and control groups during 3 follow-up periods were compared, it was found that there is a statistically significant difference between intervention and control groups (p<0.05). It was determined that there is a statistically significant difference between the groups in terms of PMS scale and sub-dimensions of anxiety, depressive affect, nervousness, pain, bloating, depressive thoughts mean scores of pre-test and 3rd follow-up (p<0.05), CONCLUSIONS: It was concluded that inhalation aromatherapy can be used for coping with PMS. It is recommended that the students suffering from PMS problems should be informed on the inhalation therapy by lavender oil. PMID- 29458935 TI - Everybody was Kung-Fu fighting-The beneficial effects of Tai Chi Qigong and self defense Kung-Fu training on psychological and endocrine health in middle aged and older men. AB - BACKGROUND: Higher age is associated to a variety of physical and mental disorders. Age-related changes in steroid secretion have been suggested to be an underlying mechanism leading to frailty, depression, and sexual dysfunction. However, Tai chi qigong and similar forms of exercise have been shown to improve a great variety of health-related parameters in older individuals. METHODS: We examined 56 self-reporting healthy men actively practicing Tai chi qigong and/or self-defense Kung-fu and 55 age-matched self-reporting healthy controls. Saliva samples were obtained in a standardized procedure for subsequent quantification of circulating testosterone and cortisol levels. In addition, depressive symptoms, life satisfaction, and sexual health were assessesd via self-report questionnaires. RESULTS: Age was negatively associated with testosterone, while no association emerged for cortisol. Tai chi qigong and/or self-defense Kung-fu training was neither associated with testosterone nor cortisol. More weekly Tai chi qigong and/or self-defense Kung-fu training (4 or more times per week) was instead associated with a lower CT-ratio, less depressive symptoms, and higher life satisfaction compared to individuals, who trained only one to three times per week. More years of Tai chi qigong and/or self-defense Kung-fu training were associated with less depressive symptoms and higher life satisfaction but not with the CT-ratio. No significant associations emerged for Tai chi qigong and/or self-defense Kung-fu training and sexual health. When compared to the age-matched controls, there is a significant effect of Tai chi, qigong and/or self-defense Kung-fu on the CT-ratio. Contrast analyses revealed a significantly lower CT ratio for the high training load group in contrast to the low training load group. Further, in contrast to the control group, the low training load group exhibits a significantly higher CT-ratio. For depression, contrast analyses revealed a significantly lower level of depression in the high training load group compared to the control group. CONCLUSION: The results indicate that Tai chi qigong and/or self-defense Kung-fu training is beneficially associated with steroid secretion patterns and mental health in aging men, when training is performed with a frequency of 4 or more trainings per week. However, the high frequency training and control group show similar steroid secretion patterns suggesting an inverted U-shaped association between Tai chi qigong and/or self defense Kung-fu training frequency and the CT-ratio in aging men. More research is needed to elucidate the underlying mechanism of this association. Still, Tai chi qigong and/or self-defense Kung-fu training provides a promising prevention strategy against age-related physical and mental deterioration in aging men. PMID- 29458936 TI - Effects of combined and resistance training on the inflammatory profile in breast cancer survivors: A systematic review. AB - OBJECTIVE: The present systematic review aimed to verify the effect of resistance and combined training on the inflammatory profile of breast cancer survivors. DESIGN: The searches were made on the platforms PsycINFO, PubMed, Cochrane, Science Direct and Scopus, from 1996 to 2017, using the keywords: cancer survivors, cancer treatment, cancer patients, breast cancer, inflammation, inflammatory profile, immune function, resistance training, strength training, weight training, physical activity, concurrent training and combined training. References of selected articles were also considered. Seven studies fulfilled the criteria adopted for analysis. RESULTS: None of these studies have shown reduced inflammatory markers in breast cancer survivors undergoing combined or isolated resistance training. CONCLUSIONS: It is not yet possible to conclude which resistance and/or combination training protocol is capable of improving the short term inflammatory profile in this population. Future studies should seek to establish how structural training variables (intensity, volume, density, intra- and inter-series recovery, among others) act on anti-inflammatory processes in breast cancer survivors. PMID- 29458937 TI - Chinese herbal medicine Dengzhan Shengmai capsule as adjunctive treatment for ischemic stroke: A systematic review and meta-analysis of randomized clinical trials. AB - OBJECTIVE: The existing eligible randomized controlled trials (RCTs) were critically appraised for the effectiveness and safety of Chinese herbal medicine Dengzhan Shenmai for ischemic stroke. DESIGN: Systematic review and meta-analysis (CRD42016042914, http://www.crd.york.ac.uk/PROSPERO). METHODS: Six electronic databases were searched from inception to May 2016. Risk ratio (RR) and mean difference (MD) with a 95% confidence interval (CI) were used as effect estimates using RevMan 5.3. Meta-analysis was performed where data were available. A summary of finding table was generated by the GRADEpro (version 3.6). RESULTS: We identified 14 RCTs involving 5206 participants. Majority of the included trials were of high risk of bias in methodological quality. For acute ischemic stroke, adding DZSM capsule to conventional therapy achieved higher Barthel Index scores (MD 22.37, 95% CI 21.34-23.40), lower neurological function deficit scores (MD - 3.73, 95% CI -5.27 to -2.19) and lower recurrence rate (RR 0.22, 95% CI 0.10, 0.46). For patients in their convalescence (or sequelae) stage of ischemic stroke, DZSM capsule was superior in improving quality of life (MD 28.8, 95% CI 7.10-50.50) and recurrence rate (RR 0.71, 95% CI 0.51-0.99) compared to placebo. No trials reported serious adverse events. CONCLUSION: DZSM capsule appears to improve neurological function, quality of life, and reduce recurrence rate based on conventional therapy for ischemic stroke. DZSM capsule seems generally safe for clinical application. However, the findings of benefit are inconclusive due to generally weak evidence, and further large, rigorous trials are still warranted. PMID- 29458938 TI - Effects of tongue cleaning on Ayurvedic digestive power and oral health-related quality of life: A randomized cross-over study. AB - OBJECTIVES: The effect of tongue cleaning on digestive power is mentioned in Ayurvedic information sources. However, no study has yet evaluated this. We aimed to evaluate the effects of tongue cleaning on digestive power from Ayurvedic viewpoint, and on oral health-related quality of life (OHRQoL) in healthy adults. DESIGN: Randomized cross-over. INTERVENTIONS: We recruited healthy adults aged 20 60 years. After randomization, the immediate intervention group started tongue cleaning with a tongue scraper every morning for 4 weeks, and then waited for 4 weeks. The delayed intervention group initially waited for 4 weeks, and then started tongue cleaning in the same way. MAIN OUTCOME MEASURES: We assessed the outcomes using the questionnaire on digestive power from Ayurvedic viewpoint, and the General Oral Health Assessment Index for OHRQoL. We estimated the effects of tongue cleaning using generalized estimating equations (GEE). We also conducted a sensitivity analysis, by comparing the changes in outcomes during the first 4 weeks of both groups. RESULTS: Of 58 participants, 57 completed the study. In GEE analysis, tongue cleaning showed improvement in some components of Ayurvedic digestive power represented by fecal and body conditions. For example, the odds ratio for improvement of constipation was 2.80 (95% CI: 1.04-7.58). The General Oral Health Assessment Index score was significantly increased by 4.33 points (95% CI: 2.18-6.48) after tongue cleaning. In sensitivity analyses, the trends of the results were similar to the main GEE analyses. CONCLUSIONS: Tongue cleaning may be an effective method to improve digestive power and OHRQoL. PMID- 29458939 TI - Association between mindfulness and interoceptive accuracy in patients with diabetes: Preliminary evidence from blood glucose estimates. AB - OBJECTIVE: Mindfulness-based interventions, which increase dispositional mindfulness, may be useful adjunctive therapies for patients with chronic diseases, including diabetes. One way that mindfulness may benefit patients with diabetes is by fostering more accurate interoception, particularly in the form of blood glucose estimate accuracy. Many people with diabetes regulate their behavior based on estimates of their blood glucose levels from interoception, but they vary in estimate accuracy. Therefore, our objective was to conduct a preliminary test of the hypothesis that, in a sample of patients with diabetes, more mindful individuals would demonstrate greater blood glucose estimate accuracy. METHODS: In a cross-sectional study, patients (N=28) with type 2 diabetes estimated their blood glucose levels immediately before their actual levels were assessed. Participants also completed two measures of mindfulness: one assessing general dispositional mindfulness and another assessing mindfulness specifically in the face of difficulty. RESULTS: Although general dispositional mindfulness was unrelated to blood glucose estimate accuracy, individuals who reported more mindfulness during difficulties were approximately four times more likely to meet established accuracy criteria. CONCLUSIONS: Mindfulness specifically during difficulties might play a role in disease-relevant interoception for patients with diabetes. Future research should aim to replicate this finding in larger and different samples, and to examine the potential role of mindfulness during difficulties in mindfulness-based interventions for patients with diabetes.

AB - AIMS: To examine the effects of aromatherapy massage on anxiety and sleep quality in patients undergoing colorectal surgery in the preoperative period. BACKGROUND: In recent years, there has been an increase in the number of studies conducted on aromatherapy massage. It is stated that studies conducted on aromatherapy massage for anxiety and sleep quality reveal contradictory results and that more research is required on the issue. DESIGN: A randomized controlled trial. METHODS: Eighty patients undergoing colorectal surgery were randomly assigned to experimental and control group. To the experimental group (n = 40), aromatherapy massage was applied in accordance with the "Back Massage Guide" using 5% lavender oil (Lavandula Hybrida) for ten minutes before surgery and the morning of surgery. The control group received standard nursing care in compliance with the hospital procedure. Data were obtained by the State Anxiety Inventory (SAI) and Richard Campbell Sleep Questionnaire (RCSQ). Results were analyzed using the t-test, Chi square test or Fisher's exact test. RESULTS: There was no baseline difference between the groups. A statistically significant difference was found between the experimental and control group in terms of the SAI and RCSQ mean scores recorded on the morning of surgery. It was determined that the SAI and RCSQ mean score of the experimental group after aromatherapy massage on the morning of surgery decreased when compared to that of the evening before surgery. CONCLUSIONS: It was found that aromatherapy massage with lavender oil increased the sleep quality and reduced the level of anxiety in patients with colorectal surgery in the preoperative period.

During the late-eighteenth century, the Scottish natural philosopher James Hutton made two important successful novel predictions. The first concerned granitic veins intruding from granite masses into strata. The second concerned what geologists now term "angular unconformities": older sections of strata overlain by younger sections, the two resting at different angles, the former typically more inclined than the latter. These predictions, I argue, are potentially problematic for selective scientific realism in that constituents of Hutton's theory that would not be considered even approximately true today played various roles in generating them. The aim here is not to provide a full philosophical analysis but to introduce the case into the debate by detailing the history and showing why, at least prima facie, it presents a problem for selective realism. First, I explicate Hutton's theory. I then give an account of Hutton's predictions and their confirmations. Next, I explain why these predictions are relevant to the realism debate. Finally, I consider which constituents of Hutton's theory are, according to current beliefs, true (or approximately true), which are not (even approximately) true, and which were responsible for these successes. PMID- 29458944 TI - The naturalism of the sciences. AB - The sciences are characterized by what is sometimes called a "methodological naturalism," which disregards talk of divine agency. In response to those who argue that this reflects a dogmatic materialism, a number of philosophers have offered a pragmatic defense. The naturalism of the sciences, they argue, is provisional and defeasible: it is justified by the fact that unsuccessful theistic explanations have been superseded by successful natural ones. But this defense is inconsistent with the history of the sciences. The sciences have always exhibited what we call a domain naturalism. They have never invoked divine agency, but have always focused on the causal structure of the natural world. It is not the case, therefore, that the sciences once employed theistic explanations and then abandoned them. The naturalism of the sciences is as old as science itself. PMID- 29458943 TI - A role for spatiotemporal scales in modeling. AB - Bogen and Woodward's distinction between data and phenomena raises the need to understand the structure of the data-to-phenomena and theory-to-phenomena inferences. I suggest that one way to study the structure of these inferences is to analyze the role of the assumptions involved in the inferences: What kind of assumptions are they? How do these assumptions contribute to the practice of identifying phenomena? In this paper, using examples from atmospheric dynamics, I develop an account of the practice of identifying the target in the data-to phenomena and theory-to-phenomena inferences in which assumptions about spatiotemporal scales play a central role in the identification of parameters that describe the target system. I also argue that these assumptions are not only empirical but they are also idealizing and abstracting. I conclude the paper with a reflection on the role of idealizations in modeling. PMID- 29458945 TI - Chance, determinism and the classical theory of probability. AB - This paper situates the metaphysical antinomy between chance and determinism in the historical context of some of the earliest developments in the mathematical theory of probability. Since Hacking's seminal work on the subject, it has been a widely held view that the classical theorists of probability were guilty of an unwitting equivocation between a subjective, or epistemic, interpretation of probability, on the one hand, and an objective, or statistical, interpretation, on the other. While there is some truth to this account, I argue that the tension at the heart of the classical theory of probability is not best understood in terms of the duality between subjective and objective interpretations of probability. Rather, the apparent paradox of chance and determinism, when viewed through the lens of the classical theory of probability, manifests itself in a much deeper ambivalence on the part of the classical probabilists as to the rational commensurability of causal and probabilistic reasoning. PMID- 29458946 TI - Heuristic analogy in Ars Conjectandi: From Archimedes' De Circuli Dimensione to Bernoulli's theorem. AB - This article investigates the way in which Jacob Bernoulli proved the main mathematical theorem that undergirds his art of conjecturing-the theorem that founded, historically, the field of mathematical probability. It aims to contribute a perspective into the question of problem-solving methods in mathematics while also contributing to the comprehension of the historical development of mathematical probability. It argues that Bernoulli proved his theorem by a process of mathematical experimentation in which the central heuristic strategy was analogy. In this context, the analogy functioned as an experimental hypothesis. The article expounds, first, Bernoulli's reasoning for proving his theorem, describing it as a process of experimentation in which hypothesis-making is crucial. Next, it investigates the analogy between his reasoning and Archimedes' approximation of the value of pi, by clarifying both Archimedes' own experimental approach to the said approximation and its heuristic influence on Bernoulli's problem-solving strategy. The discussion includes some general considerations about analogy as a heuristic technique to make experimental hypotheses in mathematics. PMID- 29458947 TI - A coherentist conception of ad hoc hypotheses. AB - What does it mean for a hypothesis to be ad hoc? One prominent account has it that ad hoc hypotheses have no independent empirical support. Others have viewed ad hoc judgements as stemming from a lack of unifiedness of the amended theory. Still others view them as merely subjective. Here I critically review these views and defend my own Coherentist Conception of Ad hocness by working out its conceptual and descriptive attractions. PMID- 29458948 TI - Leibniz on the requisites of an exact arithmetical quadrature. AB - In this paper we will try to explain how Leibniz justified the idea of an exact arithmetical quadrature. We will do this by comparing Leibniz's exposition with that of John Wallis. In short, we will show that the idea of exactitude in matters of quadratures relies on two fundamental requisites that, according to Leibniz, the infinite series have, namely, that of regularity and that of completeness. In the first part of this paper, we will go deeper into three main features of Leibniz's method, that is: it is an infinitesimal method, it looks for an arithmetical quadrature and it proposes a result that is not approximate, but exact. After that, we will deal with the requisite of the regularity of the series, pointing out that, unlike the inductive method proposed by Wallis, Leibniz propounded some sort of intellectual recognition of what is invariant in the series. Finally, we will consider the requisite of completeness of the series. We will see that, although both Wallis and Leibniz introduced the supposition of completeness, the German thinker went beyond the English mathematician, since he recognized that it is not necessary to look for a number for the quadrature of the circle, given that we have a series that is equal to the area of that curvilinear figure. PMID- 29458949 TI - What does interdisciplinarity look like in practice: Mapping interdisciplinarity and its limits in the environmental sciences. AB - In this paper we take a close look at current interdisciplinary modeling practices in the environmental sciences, and suggest that closer attention needs to be paid to the nature of scientific practices when investigating and planning interdisciplinarity. While interdisciplinarity is often portrayed as a medium of novel and transformative methodological work, current modeling strategies in the environmental sciences are conservative, avoiding methodological conflict, while confining interdisciplinary interactions to a relatively small set of pre existing modeling frameworks and strategies (a process we call crystallization). We argue that such practices can be rationalized as responses in part to cognitive constraints which restrict interdisciplinary work. We identify four salient integrative modeling strategies in environmental sciences, and argue that this crystallization, while contradicting somewhat the novel goals many have for interdisciplinarity, makes sense when considered in the light of common disciplinary practices and cognitive constraints. These results provide cause to rethink in more concrete methodological terms what interdisciplinarity amounts to, and what kinds of interdisciplinarity are obtainable in the environmental sciences and elsewhere.

PMID- 29458952 TI - Post-Vacuum-Assisted Stereotactic Core Biopsy Clip Displacement: A Comparison Between Commercially Available Clips and Surgical Clip. AB - PURPOSE: The placement of localization clips following percutaneous biopsy is a standard practice for a variety of situations. Subsequent clip displacement creates challenges for imaging surveillance and surgical planning, and may cause confusion amongst radiologists and between surgeons and radiologists. Many causes have been attributed for this phenomenon including the commonly accepted "accordion effect." Herein, we investigate the performance of a low cost surgical clip system against 4 commercially available clips. METHODS: We retrospectively reviewed 2112 patients who underwent stereotactic vacuum-assisted core biopsy followed by clip placement between January 2013 and June 2016. The primary performance parameter compared was displacement >10 mm following vacuum-assisted stereotactic core biopsy. Within the group of clips that had displaced, the magnitude of displacement was compared. RESULTS: There was a significant difference in displacement among the clip types (P < .0001) with significant pairwise comparisons between pediatric surgical clips and SecureMark (38% vs 28%; P = .001) and SenoMark (38% vs 27%; P = .0001) in the proportion displaced. The surgical clips showed a significant magnitude of displacement of approximately 25% greater average distance displaced. CONCLUSIONS: As a whole, the commercial clips performed better than the surgical clip after stereotactic vacuum-assisted core biopsy suggesting the surrounding outer component acts to anchor the central clip and minimizes clip displacement. The same should apply to tomosynthesis guided biopsy. PMID- 29458953 TI - Clinical Image Quality and Sensitivity in an Organized Mammography Screening Program. AB - PURPOSE: The study sought to examine the association between clinical image quality of mammograms and screening sensitivity. METHODS: Four radiologists evaluated the clinical image quality of 374 invasive screen-detected cancers and 356 invasive interval breast cancers for which quality evaluation of screening mammograms could be assessed from cancers diagnosed among participants in the Quebec Breast Cancer Screening Program in 2007. Quality evaluation was based on the Canadian Association of Radiologists accreditation criteria, which are similar to those of the American College of Radiology. The association between clinical quality and screening sensitivity was assessed by logistic regression. Adjusted sensitivity and adjusted sensitivity ratios were obtained through marginal standardization. No institutional review board approval was required. RESULTS: A proportion of 28% (206 of 730) of screening mammograms had lower overall quality for the majority of assessments. Positioning was the quality attribute that was the most frequently deficient. The 2-year screening sensitivity reached 68%. Sensitivity of screening was not statistically associated with the overall quality (ratio of 2-year sensitivity = 1.03; 95% confidence interval: 0.93-1.15) or with any quality attributes (positioning, exposure, compression, sharpness, artifacts, contrast). Results were similar for the 1-year sensitivity. CONCLUSIONS: Although not all mammograms in the Quebec screening program met the optimum quality required by the Canadian Association of Radiologists or American College of Radiology accreditation, the screening mammograms produced in this population-based organized screening program reached a high enough level of quality so that the remaining variation in quality is too little to impair screening sensitivity. PMID- 29458954 TI - Irreversible Electroporation in Hepatopancreaticobiliary Tumours. AB - Hepatopancreaticobiliary tumours are often diagnosed at an advanced disease stage, in which encasement or invasion of local biliary or vascular structures has already occurred. Irreversible electroporation (IRE) is an image-guided tumour ablation technique that induces cell death by exposing the tumour to high voltage electrical pulses. The cellular membrane is disrupted, while sparing the extracellular matrix of critical tubular structures. The preservation of tissue integrity makes IRE an attractive treatment option for tumours in the vicinity of vital structures such as splanchnic blood vessels and major bile ducts. This article reviews current data and discusses future trends of IRE for hepatopancreaticobiliary tumours. PMID- 29458955 TI - Percutaneous Liver Tumour Ablation: Image Guidance, Endpoint Assessment, and Quality Control. AB - Liver tumour ablation nowadays represents a routine treatment option for patients with primary and secondary liver tumours. Radiofrequency ablation and microwave ablation are the most widely adopted methods, although novel techniques, such as irreversible electroporation, are quickly working their way up. The percutaneous approach is rapidly gaining popularity because of its minimally invasive character, low complication rate, good efficacy rate, and repeatability. However, matched to partial hepatectomy and open ablations, the issue of ablation site recurrences remains unresolved and necessitates further improvement. For percutaneous liver tumour ablation, several real-time imaging modalities are available to improve tumour visibility, detect surrounding critical structures, guide applicators, monitor treatment effect, and, if necessary, adapt or repeat energy delivery. Known predictors for success are tumour size, location, lesion conspicuity, tumour-free margin, and operator experience. The implementation of reliable endpoints to assess treatment efficacy allows for completion-procedures, either within the same session or within a couple of weeks after the procedure. Although the effect on overall survival may be trivial, (local) progression-free survival will indisputably improve with the implementation of reliable endpoints. This article reviews the available needle navigation techniques, evaluates potential treatment endpoints, and proposes an algorithm for quality control after the procedure. PMID- 29458956 TI - Incidence and Economic Impact of Incidental Findings on 18F-FDG PET/CT Imaging. AB - PURPOSE: The study sought to determine the incidence of incidental findings on whole-body positron emission tomography with computed tomography (PET/CT) imaging and the average costs of investigations to follow-up or further characterize incidental findings. METHODS: Imaging reports of 215 patients who underwent whole body PET/CT imaging were retrospectively reviewed. Our provincial picture archiving and communication system was queried and patient charts were reviewed to identify all investigations performed to follow-up incidental findings within 1 year of the initial PET/CT study. Costs of follow-up imaging studies (professional and technical components) and other diagnostic tests and procedures were determined in Canadian dollars (CAD) and U.S. dollars (USD) using the 2015 Ontario Health Insurance Plan Schedule of Benefits and Fees and 2016 U.S. Medicare Physician Fee Schedule, respectively. RESULTS: At least 1 incidental finding was reported in 161 reports (74.9%). The mean number of incidental findings ranged from 0.64 in patients <45 years of age to 2.2 in patients 75 years of age and older. Seventy-five recommendations for additional investigations were made for 64 (30%) patients undergoing PET/CT imaging, and 14 of those were carried out specifically to follow-up incidental findings. Averaged across all 215 patients, the total cost of investigations recommended to follow up incidental findings was CAD$105.51 (USD$127.56) per PET/CT study if all recommendations were acted on, and CAD$22.77 (USD$29.14) based on investigations actually performed. CONCLUSIONS: As the incidence of incidental findings increases with age and a larger proportion of elderly patients is expected as population demographics change, it will be increasingly important to consider incidental findings on PET/CT imaging with standardized approaches to follow-up. PMID- 29458957 TI - Magnetic Resonance Imaging and Computed Tomography of Cardiac Masses and Pseudomasses in the Atrioventricular Groove. AB - The atrioventricular (AV) groove constitutes the anatomic space separating the atria and ventricles. The AV groove is often difficult to visualize at echocardiography, and suspected lesions can be further assessed with cardiac computed tomography or magnetic resonance imaging. AV groove lesions may originate from within the AV groove or extend into this space from adjacent structures. The differential diagnosis for AV groove lesions is often wide, but a precise diagnosis can sometimes be made. This pictorial essay illustrates the magnetic resonance imaging and computed tomography appearance of common and uncommon AV groove lesions, and attempts to provide a logical framework for differential diagnosis when confronted with a known or suspected lesion at cross sectional imaging. PMID- 29458958 TI - The Accuracy of Colorectal Cancer Detection by Computed Tomography in the Unprepared Large Bowel in a Community-Based Hospital. AB - PURPOSE: This retrospective study examined the performance of general radiologists in a community-based hospital in detecting colorectal cancer (CRC) with computed tomography (CT) in the unprepared large bowel. METHODS: The pathology database at a community hospital over the past 7 years (2009-2015) was retrospectively analysed for pathologically proven CRC (924 cases). The provincial hospital information profile for these patients was reviewed to determine if they had an abdominal CT for any reason in the year prior to biopsy. Metrics such as age, sex, time between the CT and biopsy or surgery, whether CRC was initially detected by the radiologist, and if this was an emergency presentation was evaluated. In the cases where CRC was not identified, the CT scans were reanalysed to determine if the CRC was identifiable in retrospect. The sensitivity of detecting CRC by CT scan in the unprepared large bowel was calculated. RESULTS: Of the 924 biopsy proven CRC cases, 22% (207 of 924) of the patients had a CT prior to biopsy. Of these cases, 47% (97 of 207) presented on an emergency basis. Of the cases with imaging in the year prior, about 60% (125 of 207) had cancer prospectively detected by the radiologist. Upon re-examination of the cases in which CRC was not initially detected, 59% were visualized in retrospect. CONCLUSIONS: Community general radiologists can successfully detect CRC with a high degree of accuracy. Reformatted images, bowel wall thickening when regional nodes are prominent, and minimizing oral contrast were helpful in improving detection.

PMID- 29458960 TI - Challenging Standard-of-Care Paradigms in the Precision Oncology Era. AB - The pace of genomic and immunological breakthroughs in oncology is accelerating, making it likely that large randomized trials will increasingly become outdated before their completion. Traditional clinical research/practice paradigms must adapt to the reality unveiled by genomics, especially the need for customized drug combinations, rather than one-size-fits-all monotherapy. The raison-d'etre of precision oncology is to offer 'the right drug for the right patient at the right time', a process enabled by transformative tissue and blood-based genomic technologies. Genomically targeted therapies are most suitable in early disease, when molecular heterogeneity is less pronounced, while immunotherapy is most effective against tumors with unstable genomes. Next-generation cancer research/practice models will need to overcome the tyranny of tradition and emphasize an innovative, precise and personalized patient-centric approach. PMID- 29458961 TI - The Genetic/Non-genetic Duality of Drug 'Resistance' in Cancer. AB - Drug resistance is a serious impediment to the treatment of cancer. However, the mechanisms involved remain poorly understood. While it is widely held that the phenomenon is genetic in nature, emerging evidence suggests that non-genetic mechanisms may also be important. Furthermore, at least in some cases, refractoriness to treatment can be reversed by epigenetic reprogramming, and combination and intermittent therapies, as opposed to sustained monotherapy, appear more effective in attenuating it. Here we iterate the confusion in understanding the phenomenon by which cancer cells evade drug response and underscore the need to recognize the genetic/non-genetic duality of drug resistance in cancer. We discuss how ecological and evolutionary principles may help to reconcile the duality and may even offer new treatment strategies. PMID- 29458963 TI - B-Cell Metabolic Remodeling and Cancer. AB - Cells of the immune system display varying metabolic profiles to fulfill their functions. B lymphocytes overcome fluctuating energy challenges as they transition from the resting state and recirculation to activation, rapid proliferation, and massive antibody production. Only through a controlled interplay between metabolism, extracellular stimuli, and intracellular signaling can successful humoral responses be mounted. Alterations to this balance can promote malignant transformation of B cells. The metabolic control of B-cell fate is only partially understood. Here, we provide a compelling overview of the current state of the art and describe the main metabolic features of B cells during normal development and oncogenesis, with emphasis on the major B-cell transcriptional and metabolic regulators, including myelocytomatosis virus oncogene cellular homolog (Myc) and hypoxia-inducible factor 1-alpha (HIF 1alpha). PMID- 29458962 TI - Re-Emergence of Dendritic Cell Vaccines for Cancer Treatment. AB - Dendritic cells (DCs) are essential in immunity owing to their role in activating T cells, thereby promoting antitumor responses. Tumor cells, however, hijack the immune system, causing T cell exhaustion and DC dysfunction. Tumor-induced T cell exhaustion may be reversed through immune checkpoint blockade (ICB); however, this treatment fails to show clinical benefit in many patients. While ICB serves to reverse T cell exhaustion, DCs are still necessary to prime, activate, and direct the T cells to target tumor cells. In this review we provide a brief overview of DC function, describe mechanisms by which DC functions are disrupted by the tumor microenvironment, and highlight recent developments in DC cancer vaccines. PMID- 29458965 TI - The Sympathetic Nervous System Drives Tumor Angiogenesis. AB - Neurobiology is increasingly contributing to cancer research. Recent work indicates that noradrenaline released by sympathetic adrenergic nerves in prostate cancer can stimulate beta-adrenoceptors in endothelial cells. This leads to the alteration of endothelial cell metabolism toward the inhibition of oxidative phosphorylation and the induction of an angiogenic switch that fuels cancer progression. These findings suggest that the sympathetic nervous system is a higher-level control of tumor angiogenesis that could be targeted in clinical oncology.

However, clinical trials have not adequately tested the concept of c-Met pathway inhibition due to the lack of appropriate patient selection criteria. PMID- 29458967 TI - Improving Cancer Immunotherapies through Empirical Neoantigen Selection. AB - Targeting neoantigens has become an attractive strategy for cancer immunotherapy.

PMID- 29458968 TI - Influence of sad mood induction on implicit self-esteem and its relationship with symptoms of depression and anxiety. AB - BACKGROUND AND OBJECTIVES: Implicit self-esteem (ISE) refers to the valence of triggered associations when the self is activated. Despite theories, previous studies often fail to observe low ISE in depression and anxiety. It is feasible that sad mood is required to activate dysfunctional self-associations. The present study tested the following hypotheses: i) ISE is lower following a sad mood induction (SMI); ii) the relationship between ISE and level of depression/anxiety symptoms is relatively strong when ISE is measured during sad mood; iii) individuals with higher levels of depression/anxiety symptoms will show a relatively large decrease in ISE following a SMI. METHODS: In this mixed designed study, university students completed the self-esteem implicit association test (IAT) either at baseline (control condition; n = 46) or following a SMI (experimental condition; n = 49). To test the third hypothesis, a SMI and IAT were also given in the control condition. Both conditions completed self-report measures of explicit self-esteem (ESE), and symptoms of depression and anxiety. RESULTS: There was no support for the first two hypotheses, but some support that symptoms of anxiety correlated with larger decreases in ISE following a SMI which partly supported the third hypothesis. This disappeared when controlling for multiple testing. LIMITATIONS: Results are limited to non clinical participants. CONCLUSIONS: While ISE was robust against increases in sad mood, there was some tentative support that symptoms of anxiety were related to larger decreases in ISE following a SMI. PMID- 29458964 TI - Metabolism, Activity, and Targeting of D- and L-2-Hydroxyglutarates. AB - Isocitrate dehydrogenases (IDH1/2) are frequently mutated in multiple types of human cancer, resulting in neomorphic enzymes that convert alpha-ketoglutarate (alpha-KG) to 2-hydroxyglutarate (2-HG). The current view on the mechanism of IDH mutation holds that 2-HG acts as an antagonist of alpha-KG to competitively inhibit the activity of alpha-KG-dependent dioxygenases, including those involved in histone and DNA demethylation. Recent studies have implicated 2-HG in activities beyond epigenetic modification. Multiple enzymes have been discovered that lack mutations but that can nevertheless produce 2-HG promiscuously under hypoxic or acidic conditions. Therapies are being developed to treat IDH-mutant cancers by targeting either the mutant IDH enzymes directly or the pathways sensitized by 2-HG. PMID- 29458969 TI - Hospital readmission following open, single-stage, elective abdominal wall reconstructions using acellular dermal matrix affects long-term hernia recurrence rate. AB - BACKGROUND: We evaluated the incidence of and the risk factors for readmission in patients who underwent abdominal wall reconstruction (AWR) using acellular dermal matrix (ADM) and assess whether readmission affects AWR long-term outcomes. METHODS: A retrospective, single-center study of patients underwent AWR with ADM was conducted. The primary outcome was the incidence of unplanned readmission within 30 days after the initial discharge post-AWR. Secondary outcomes were surgical site occurrence (SSO) and hernia recurrence at follow-up. RESULTS: Of 452 patients (mean age, 59 years; mean follow-up, 35 months), 29 (6.4%) were readmitted within 30 days. Most readmissions were due to SSO (44.8%) or wound infections (12.8%). The hernia recurrence rate was significantly higher in readmitted patients (17.2% vs 9.9%; P = 0.044). Wider defects, prolonged operative time, and coronary artery disease were independent predictors of readmission. CONCLUSIONS: Readmission is associated with hernia recurrence on long-term follow-up. SSO is the most common cause for readmission. PMID- 29458970 TI - Higher robotic colorectal surgery volume improves outcomes. AB - In this study we sought to assess the effect of surgeon volume on outcomes of robotic colorectal operations performed by surgeons with low or high volume across a large health system. We performed a retrospective review of colon or rectal resections performed between January 1, 2013 and January 1, 2017 within the Providence Health System Hospitals. Procedures were separated into those performed by surgeons with high volume (30 or more robotic cases per year) vs. low volume. A total of 8 high volume and 41 low volume robotic surgeons were included in the study. High volume surgeons had a significantly shorter length of hospital stay, lower conversion rate, and lower total hospital cost. There were no differences in complications or rate of readmission. Many studies have shown that outcomes improve with increased experience. These data suggest that if a surgeon maintains robotic experience there can be improvements in cost, length of stay and conversion rates. PMID- 29458971 TI - Continuous fractional-order Zero Phase Error Tracking Control. AB - A continuous time fractional-order feedforward control algorithm for tracking desired time varying input signals is proposed in this paper. The presented controller cancels the phase shift caused by the zeros and poles of controlled closed-loop fractional-order system, so it is called Fractional-Order Zero Phase Tracking Controller (FZPETC). The controlled systems are divided into two categories i.e. with and without non-cancellable (non-minimum-phase) zeros which stand in unstable region or on stability boundary. Each kinds of systems has a targeted FZPETC design control strategy. The improved tracking performance has been evaluated successfully by applying the proposed controller to three different kinds of fractional-order controlled systems. Besides, a modified quasi perfect tracking scheme is presented for those systems which may not have available future tracking trajectory information or have problem in high frequency disturbance rejection if the perfect tracking algorithm is applied. A simulation comparison and a hardware-in-the-loop thermal peltier platform are shown to validate the practicality of the proposed quasi-perfect control algorithm. PMID- 29458972 TI - Tracking control of air-breathing hypersonic vehicles with non-affine dynamics via improved neural back-stepping design. AB - This study considers the design of a new back-stepping control approach for air breathing hypersonic vehicle (AHV) non-affine models via neural approximation. The AHV's non-affine dynamics is decomposed into velocity subsystem and altitude subsystem to be controlled separately, and robust adaptive tracking control laws are developed using improved back-stepping designs. Neural networks are applied to estimate the unknown non-affine dynamics, which guarantees the addressed controllers with satisfactory robustness against uncertainties. In comparison with the existing control methodologies, the special contributions are that the non-affine issue is handled by constructing two low-pass filters based on model transformations, and virtual controllers are treated as intermediate variables such that they aren't needed for back-stepping designs any more. Lyapunov techniques are employed to show the uniformly ultimately boundedness of all closed-loop signals. Finally, simulation results are presented to verify the tracking performance and superiorities of the investigated control strategy. PMID- 29458973 TI - Robust and novel two degree of freedom fractional controller based on two-loop topology for inverted pendulum. AB - A rotary single inverted pendulum (RSIP) typically represents a space booster rocket, Segway and similar systems with unstable equilibrium. This paper proposes a novel two degree of freedom (2-DOF) fractional control strategy based on 2-loop topology for RSIP system which can be extended to control the systems with unstable equilibrium. It comprises feedback and feed-forward paths. Primary controller relates the perturbation attenuation while the secondary controller is accountable for set point tracking. To tune the parameters of proposed fractional controller a simple graphical tuning method based on frequency response is used. The study will serve the outstanding experimental results for both, stabilization and trajectory tracking tasks. The study will also serve to present a comparison of the performance of the proposed controller with the 1-DOF FOPID controller and sliding mode controller (SMC) for the RSIP system. Further to confirm the usability of the proposed controller and to avoid the random perturbations sensitivity, robustness, and stability analysis through fractional root-locus and Bode-plot is investigated. PMID- 29458975 TI - The interstitial macrophage: A long-neglected piece in the puzzle of lung immunity. AB - Lung macrophages have mostly been studied considering only their most accessible and well-defined representative, the alveolar macrophage (AM). In contrast, the identity and putative immune functions of their tissue counterpart, the interstitial macrophage (IM), have long remained much more elusive. Yet, recent evidence supports the notion that IMs perform important immune functions in the lung, notably in terms of innate immunoregulation. Here, we review current knowledge on the phenotype, ontogeny and function of IMs and propose strategies for the unambiguous identification and study of this important and dynamic lung innate immune cell population. PMID- 29458974 TI - Dynamic patterns and predictors of hydroxychloroquine nonadherence among Medicaid beneficiaries with systemic lupus erythematosus. AB - BACKGROUND: Hydroxychloroquine (HCQ) is the standard of care medication for most SLE patients, however nonadherence is common. We investigated longitudinal patterns and predictors of nonadherence to HCQ in a U.S. SLE cohort of HCQ initiators. METHODS: We used Medicaid data from 28 states to identify adults 18 65 years with prevalent SLE. We included HCQ initiators following >=6 months without use, and required >=1 year of follow-up after first dispensing (index date). We used the proportion of days covered (PDC) to describe overall HCQ adherence (<80% = nonadherent) and novel group-based trajectory models (GBTM) to examine monthly patterns (<80% of days/month covered = nonadherent), during the first year of use. Multivariable multinomial logistic regression models were used to examine predictors of nonadherence. RESULTS: We identified 10,406 HCQ initiators with SLE. Mean age was 38 (+/-12) years, 94% were female, 42% black, 31% white; 85% had a mean PDC < 80%. In our 4-group GBTM, 17% were persistent adherers, 36% persistent nonadherers, and 47% formed two dynamic patterns of partial adherence. Adherence declined for most patients over the first year. Compared to persistent adherers, the odds of nonadherence were increased for blacks and Hispanics vs. whites and for younger ages vs. older; increased SLE related comorbidities were associated with reduced odds of nonadherence for persistent nonadherers (0.95, 95% CI: 0.91-0.99). CONCLUSIONS: Among HCQ initiators with SLE, we observed poor adherence which declined for most over the first year of use. HCQ adherence is a dynamic behavior and further studies of associated predictors, outcomes, and interventions should reflect this. PMID- 29458976 TI - Small cell cancers of the female genital tract: Molecular and clinical aspects. AB - OBJECTIVE: Extra-pulmonary small cell carcinomas of the gynecologic tract (EPSCC GTs) are a rare group of aggressive malignancies associated with poor prognoses and limited treatment options. Here, we review the clinical and molecular aspects of EPSCC-GTs and discuss how understanding their molecular features can assist in their diagnosis and the identification of novel effective treatments. METHODS: We searched PubMed and Scopus for articles using the following keywords: "small cell carcinoma" in combination with "neuroendocrine", "ovary", "vagina", "fallopian tube", "vulva", "endometrium", "uterus", "cervix", or "gynecologic". Articles were limited to those published in English from January 1984 to October 2017. RESULTS: EPSCC-GTs account for 2% of all gynecologic malignancies. The molecular features of EPSCC-GTs are largely understudied and unknown, with the exception of small cell carcinoma (SCC) of the ovary, hypercalcemic type (SCCOHT) and SCC of the cervix (SCCC). In nearly all cases, SCCOHT displays mutation in a single gene, SMARCA4, a member of the SWI/SNF chromatin remodeling complex. The loss of expression of the SWI/SNF protein SMARCA2 is another feature of SCCOHT. Dual negative staining for SMARCA2 and SMARCA4 is specific for SCCOHT and is generally used by gynecologic pathologists for the accurate diagnosis of this malignancy. Mutational analysis of SCCC has shown alterations in PIK3CA, KRAS and TP53, of which the last is the most common, although other actionable mutations have been identified. The molecular features of other EPSCC-GTs are largely unknown. CONCLUSIONS: Due to their rarity, the majority of EPSCC-GTs are understudied and poorly understood. As demonstrated in the case of SCCOHT, unraveling the mutational profiles of these tumors can lead to improved diagnosis and the identification of novel therapeutic targets.

AB - INTRODUCTION: Epithelial ovarian cancer (EOC) is notoriously difficult to diagnose in its earlier and more treatable stages, making it one of the deadliest cancers in women. Comorbid diabetes is associated with poor prognosis in EOC and pro-growth insulin signalling is often considered to be the driving factor. However, EOC cells are also highly glycolytic and insulin-independent glucose uptake is essential to their metabolism. Evidence of gluconeogenesis in cancer in vivo suggests that the normal concentration of circulating glucose does not meet the energy demands of the tumor and may therefore be a limiting factor in cancer cell metabolism. Diabetics have elevated blood glucose that has the potential to meet these energy demands and facilitate cancer progression. METHODS: To determine whether hyperglycemia is a potentially modifiable factor independent of insulin, orthotopic ovarian tumors were induced in mice with acute Type 1 (hypo insulinemic) or Type 2 (hyper-insulinemic) diabetes. RESULTS: Hyperglycemia accelerated the growth of ovarian tumors in a glucose concentration-dependent manner and significantly shortened overall survival. Reciprocally, the presence of a tumor improved impaired glucose tolerance in both Type 1 and Type 2 diabetes. In mice with chronic Type 1 diabetes, hyperglycemia limited tumor growth without changing overall survival, indicating that systemic metabolic stress can accelerate time to death independent of primary tumor size. When modeled in vitro, long-term culture in 25mM vs 6mM glucose resulted in significantly different growth and metabolism. CONCLUSIONS: Taken together, this study shows that systemic metabolic disturbances can have a profound impact on both the growth of ovarian tumors and on overall survival.

AB - Fossil bird data (community composition and taphonomic profiles) are used here to infer the environmental context of the Oldowan-Acheulean transitional period at Olduvai Gorge, Tanzania. This is the first comprehensive report on the Middle Bed II avifauna and includes fossils excavated by the Olduvai Geochronology and Archaeology Project (OGAP) and recently rediscovered fossils collected by Mary Leakey. Crane, ibis, darter, owl, raptor, crow, and vulture are reported from Bed II for the first time. The presence of these taxa, absent earlier in this Bed, point to a general opening and drying of the landscape with grassland and open woodland expansion. Taxa associated with dense, emergent wetland vegetation, such as dabbling ducks and rails, are uncommon and less diverse than earlier in Bed II. This suggests more mature wetlands with clearer waters. Cormorants continue to be common, but are less diverse. Cormorants and other roosting taxa provide evidence of trees in the area. Compared to lowermost Bed II, the Middle to Upper Bed II landscape is interpreted here as more open and drier (but not necessarily more arid), with matured wetlands, scattered trees, and a greater expansion of grasslands. PMID- 29458979 TI - The effects of long duration chronic exposure to hexavalent chromium on single live cells interrogated by scanning electrochemical microscopy. AB - Chromium is a useful heavy metal which has been employed in numerous industry and house applications. However, there are several known health risks associated with its uses. Cr (VI) is a toxic heavy metal format which serves no essential biological role in humans. It has been associated with oxidative stress, cytotoxicity, and carcinogenicity. Contamination of groundwater or soil due to improper handling lead to long term environmental damage. This study explores the effects of long duration chronic exposure to Cr (VI) on live human cells. Herein, scanning electrochemical microscopy (SECM) depth scan imaging was employed to monitor the membrane permeability of single live human bladder cancer (T24) cells following incubation with various Cr (VI) concentration stimuli. SECM was used to provide insights into the long duration effects on membrane homeostasis of individual cells exposed to constant levels of Cr (VI). Further investigation of total population viability was performed by MTT assay. Dependent on the exposure time, transition between three distinct trends was observed. At short incubation times (<=1-3 h) with low concentrations of Cr (VI) (0-10 MUM), membrane permeability was largely unaffected. As time increased a decrease in membrane permeability coefficient was observed, reaching a minimum at 3-6 h. Following this a dramatic increase in membrane permeability was observed as cell viability decreased. Higher concentrations were also found to accelerate the timeframe at which these trends occurred. These findings further demonstrate the strength of SECM as a bioanalytical technique for monitoring cellular homeostasis.

AB - BACKGROUND: Abdominal pain is one of the most common chief complaints of patients presenting to emergency departments, and emergency physicians (EPs) often evaluate patients with right lower quadrant abdominal pain. Ovarian torsion is a rare cause of abdominal pain, but early diagnosis is essential for salvage of the affected ovary. The diagnostic study of choice for ovarian torsion is a pelvic ultrasound with color Doppler, but it is important for EPs and radiologists to be aware of findings of ovarian torsion that might appear on computed tomography (CT). CASE REPORT: We present a case of a young female with right lower quadrant abdominal pain with CT evidence of ovarian torsion that was not recognized; the patient was discharged and then called back when the study was over-read as concerning for ovarian torsion. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: The presence of radiographic findings associated with ovarian torsion on a CT scan should encourage an EP to order a pelvic ultrasound with color Doppler (if available) and obtain an obstetrics/gynecology consult.

AB - BACKGROUND/PURPOSE: Medical inpatients are at increased risk of QT interval prolongation due to multiple risk actors and QT prolonging drugs. This study aimed to identify the prevalence of risk factors for QT prolongation; QT prolonging medications; associated drug-drug interactions (QT-DDIs); their predictors; and TdP (torsades de pointes) risks of drugs. METHODS: This cohort study was carried out in medical wards of two tertiary hospitals in Khyber Pakhtunkhwa, Pakistan. The QT-DDIs were identified using Micromedex DrugReax(r) and AZCERT (Arizona Center for Education and Research on Therapeutics) QT drugs lists. AZCERT QT drugs lists were used to identify TdP risks. Logistic regression analysis was performed to identify predictors of QT-DDIs. RESULTS: Total 400 patients were included in this study. The most frequent QT prolonging risk factors included use of >=1 QT prolonging drugs (74.5%), female gender (55%) and diabetes mellitus (36.3%). Total 487 QT prolonging drugs were identified. According to AZCERT classification, 33.8% of the interacting drugs were included in list-1 (known risk of TdP), 0.9% in list-2 (possible risk of TdP) and 58.8% in list-3 (conditional risk of TdP). The occurrence of QT-DDIs was significantly associated with >=10 prescribed medications (p = 0.01), chronic liver disease (p = 0.05), chronic obstructive pulmonary disease (p = 0.03), gastroenteritis (p = 0.02), antimicrobials (p < 0.001), antiemetics (p < 0.001) and antinausea (p < 0.001). CONCLUSION: A substantial number of patients were exposed to risk factors for QT prolongation; and QT prolonging drugs such as proton pump inhibitors, antimicrobials and diuretics which may lead to serious outcomes.

PMID- 29458993 TI - Longitudinal association of metabolic syndrome and dietary patterns: A 13-year prospective population-based cohort study. AB - BACKGROUND AND AIMS: Diet is a potential factor contributing to the development of the Metabolic Syndrome (MetS). This longitudinal study with repeated measurements of dietary intake was thus conducted to examine the longitudinal association between major dietary patterns and risk of MetS. METHODS AND RESULTS: The study was conducted within the framework of the Isfahan Cohort Study (ICS), in which 1387 participants were followed from 2001 to 2013. Validated food frequency questionnaire, anthropometric measurements, blood pressure, fasting serum lipids and blood sugars were evaluated in three phases of the study. Mixed effect Logistic and Cumulative Logit regressions were applied to evaluate the longitudinal associations between dietary patterns change and MetS and number of MetS components. Three dietary patterns were identified: Healthy, Iranian and Western dietary patterns. After adjustment for potential confounders, the higher scores of Healthy diet were inversely associated with the risk of MetS and number of MetS components (OR: 0.50, 95% CI: 0.36-0.70, OR: 0.52, 95% CI: 0.39-0.70, respectively). The greater adherence to the Iranian diet was positively associated with the risk of MetS and number of MetS components (OR: 1.28, 95% CI: 1.01-1.65, OR: 1.45, 95% CI: 1.16-1.81, respectively). The Western dietary pattern did not show any significant associations. CONCLUSION: Adherence to a Healthy diet was associated with lower risk of MetS even in a developing country setting. However, the Iranian diet was positively associated with the risk of MetS. These results may guide the development of improved preventive nutrition interventions in this adult population.

PMID- 29458996 TI - Quantitative comparisons of three automated methods for estimating intracranial volume: A study of 270 longitudinal magnetic resonance images. AB - Total intracranial volume (TIV) is often used as a measure of brain size to correct for individual variability in magnetic resonance imaging (MRI) based morphometric studies. An adjustment of TIV can greatly increase the statistical power of brain morphometry methods. As such, an accurate and precise TIV estimation is of great importance in MRI studies. In this paper, we compared three automated TIV estimation methods (multi-atlas likelihood fusion (MALF), Statistical Parametric Mapping 8 (SPM8) and FreeSurfer (FS)) using longitudinal T1-weighted MR images in a cohort of 70 older participants at elevated sociodemographic risk for Alzheimer's disease. Statistical group comparisons in terms of four different metrics were performed. Furthermore, sex, education level, and intervention status were investigated separately for their impacts on the TIV estimation performance of each method. According to our experimental results, MALF was the least susceptible to atrophy, while SPM8 and FS suffered a loss in precision. In group-wise analysis, MALF was the least sensitive method to group variation, whereas SPM8 was particularly sensitive to sex and FS was unstable with respect to education level. In terms of effectiveness, both MALF and SPM8 delivered a user-friendly performance, while FS was relatively computationally intensive. PMID- 29458997 TI - Psychiatric Symptom Dimensions Are Associated With Dissociable Shifts in Metacognition but Not Task Performance. AB - BACKGROUND: Distortions in metacognition-the ability to reflect on and control other cognitive processes-are thought to be characteristic of poor mental health. However, it remains unknown whether such shifts in self-evaluation are due to specific alterations in metacognition and/or a downstream consequence of changes in decision-making processes. METHODS: Using perceptual decision making as a model system, we employed a computational psychiatry approach to relate parameters governing both decision formation and metacognitive evaluation to self reported transdiagnostic symptom dimensions in a large general population sample (N = 995). RESULTS: Variability in psychopathology was unrelated to either speed or accuracy of decision formation. In contrast, leveraging a dimensional approach, we revealed independent relationships between psychopathology and metacognition: a symptom dimension related to anxiety and depression was associated with lower confidence and heightened metacognitive efficiency, whereas a dimension characterizing compulsive behavior and intrusive thoughts was associated with higher confidence and lower metacognitive efficiency. Furthermore, we obtained a robust double dissociation-whereas psychiatric symptoms predicted changes in metacognition but not decision performance, age predicted changes in decision performance but not metacognition. CONCLUSIONS: Our findings indicate a specific and pervasive link between metacognition and mental health. Our study bridges a gap between an emerging neuroscience of decision making and an understanding of metacognitive alterations in psychopathology. PMID- 29458998 TI - Role of Striatal Direct Pathway 2-Arachidonoylglycerol Signaling in Sociability and Repetitive Behavior. AB - BACKGROUND: Endocannabinoid signaling plays an important role in regulating synaptic transmission in the striatum, a brain region implicated as a central node of dysfunction in autism spectrum disorder. Deficits in signaling mediated by the endocannabinoid 2-arachidonoylglycerol (2-AG) have been reported in mouse models of autism spectrum disorder, but a causal role for striatal 2-AG deficiency in phenotypes relevant to autism spectrum disorder has not been explored. METHODS: Using conditional knockout mice, we examined the electrophysiological, biochemical, and behavioral effects of 2-AG deficiency by deleting its primary synthetic enzyme, diacylglycerol lipase alpha (DGLalpha), from dopamine D1 receptor-expressing or adenosine A2a receptor-expressing medium spiny neurons (MSNs) to determine the role of 2-AG signaling in striatal direct or indirect pathways, respectively. We then used viral-mediated deletion of DGLalpha to study the effects of 2-AG deficiency in the ventral and dorsal striatum. RESULTS: Targeted deletion of DGLalpha from direct-pathway MSNs caused deficits in social interaction, excessive grooming, and decreased exploration of a novel environment. In contrast, deletion from indirect-pathway MSNs had no effect on any measure of behavior examined. Loss of 2-AG in direct-pathway MSNs also led to increased glutamatergic drive, which is consistent with a loss of retrograde feedback inhibition. Subregional DGLalpha deletion from the dorsal striatum produced deficits in social interaction, whereas deletion from the ventral striatum resulted in repetitive grooming. CONCLUSIONS: These data suggest a role for 2-AG deficiency in social deficits and repetitive behavior, and they demonstrate a key role for 2-AG in regulating striatal direct-pathway MSNs.

AB - We report a case of successful combined heart liver transplant in a patient with a congenital solitary kidney. The patient had normal renal function before combined heart-liver transplantation and developed acute kidney injury requiring slow continuous dialysis and subsequent intermittent dialysis for almost 8 weeks post transplantation. Her renal function recovered and she remains off dialysis now 7 months post transplantation. She only currently has mild chronic renal insufficiency. We believe this is the first reported case of successful heart liver transplant in a patient with a congenital solitary kidney. PMID- 29459000 TI - In vitro activity of various antibiotics against clinical strains of Legionella species isolated in Japan. AB - The activities of various antibiotics against 58 clinical isolates of Legionella species were evaluated using two methods, extracellular activity (minimum inhibitory concentration [MIC]) and intracellular activity. Susceptibility testing was performed using BSYEalpha agar. The minimum extracellular concentration inhibiting intracellular multiplication (MIEC) was determined using a human monocyte-derived cell line, THP-1. The most potent drugs in terms of MICs against clinical isolates were levofloxacin, garenoxacin, and rifampicin with MIC90 values of 0.015 MUg/ml. The activities of ciprofloxacin, pazufloxacin, moxifloxacin, clarithromycin, and azithromycin were slightly higher than those of levofloxacin, garenoxacin, and rifampicin with an MIC90 of 0.03-0.06 MUg/ml. Minocycline showed the highest activity, with an MIC90 of 1 MUg/ml. No resistance against the antibiotics tested was detected. No difference was detected in the MIC distributions of the antibiotics tested between L. pneumophila serogroup 1 and L. pneumophila non-serogroup 1. The MIECs of ciprofloxacin, pazufloxacin, levofloxacin, moxifloxacin, garenoxacin, clarithromycin, and azithromycin were almost the same as their MICs, with MIEC90 values of 0.015-0.06 MUg/ml, although the MIEC of minocycline was relatively lower and that of rifampicin was higher than their respective MICs. No difference was detected in the MIEC distributions of the antibiotics tested between L. pneumophila serogroup 1 and L. pneumophila non-serogroup 1. The ratios of MIEC:MIC for rifampicin (8) and pazufloxacin (2) were higher than those for levofloxacin (1), ciprofloxacin (1), moxifloxacin (1), garenoxacin (1), clarithromycin (1), and azithromycin (1). Our study showed that quinolones and macrolides had potent antimicrobial activity against both extracellular and intracellular Legionella species. The present data suggested the possible efficacy of these drugs in treatment of Legionella infections. PMID- 29459001 TI - Three point transfusion risk score in hepatectomy: an external validation using the American College of Surgeons - National Surgical Quality Improvement Program (ACS-NSQIP). AB - BACKGROUND: Risk of red blood cell transfusion (RBCT) in partial hepatectomy is 17-27%; strategies to reduce transfusions can be targeted in patients at increased risk. A Three Point Transfusion Risk Score (TRS) was previously developed to predict patients' risk of transfusion during and following hepatectomy. Here, it was subject to external validation using the ACS-NSQIP database. METHODS: TRIPOD guidelines were followed. A validation cohort was created with the ACS-NSQIP dataset. Risk groups for RBCT were created using the TRS: anemia (hematocrit <=36%), major liver resection (>=4 segments) and primary liver malignancy. Concordance index was used to assess the discrimination. The Hosmer-Lemeshow test for goodness of fit and calibration curves were used to assess calibration. RESULTS: Of 2854 hepatectomies, 18.9% received RBCT. The TRS stratified patients from low (8.5% risk of RBCT) to very high risk (40.6%) of RBCT. The concordance was 0.68 (95% CI 0.66-0.70). Hosmer-Lemeshow test and calibration curves supported good predictive performance of the model. CONCLUSION: The TRS adequately discriminated risk of RBCT in an external sample of patients undergoing hepatectomy. It provides a simple method to identify patients at high transfusion risk. It can be used to tailor patient blood management initiatives and reduce the use of RBCT. PMID- 29459002 TI - Reappraisal of post-pancreatectomy hemorrhage (PPH) classifications: do we need to redefine grades A and B? AB - BACKGROUND: Post-pancreatectomy hemorrhage (PPH) remains a major complication. The aim of this study was to reappraise the International Study Group of Pancreatic Surgery (ISGPS) classification. METHODS: The clinical utility of the ISGPS classification was tested on consecutive pancreatic resections performed at the Pancreas Institute of the University of Verona Hospital. RESULTS: PPH occurred in 65 of the 2429 patients (6.8%) undergoing pancreatic resection. Outcome of patients without PPH and with grade A PPH were comparable in terms of mortality, length of stay, ICU stay and readmission. Patients with grade B late and mild and grade B early and severe PPH had similar hospital stay and mortality rates, but differed in relaparotomy rate (10.1 vs. 81.2%, p < 0.01). Replacing "time of PPH onset" criterion with post-operative pancreatic fistula (POPF), severe PPH alone, mild PPH/POPF and severe PPH/POPF differed significantly for hospital stay (14 vs. 23 vs. 35 days, p < 0.01) and mortality rate (0 vs. 4 vs. 25%, p = 0.05). CONCLUSION: Grade A PPH shared the same outcome of patients without PPH. Grade B PPH included two categories of patients with different treatment modalities. The use of "concomitant POPF" instead of "time of onset" segregated three discrete categories that differed significantly in terms of clinical outcomes and management.

AB - INTRODUCTION: The objective of this study was to evaluate the awareness and training needs on biosimilar drugs in Primary Care (PC) physicians. MATERIAL AND METHODS: Descriptive cross-sectional study based on an on-line questionnaire with a total of 34 multiple choice questions, published on the SEMERGEN website. The main Knowledge areas were: biosimilar definition; regulatory and legal framework; prescription, traceability, interchangeability and pharmacovigilance; availability of biosimilars in the PC setting, and the biosimilars contribution to sustainability. The software used for the analysis and data processing was the Barbwin 7.5. RESULTS: An analysis was performed on the responses from 701 questionnaires completed. There was a slight majority (57%) of women participants. The majority of participant worked in urban centres (60.91%). The definition of biosimilar was not known by 58% of those that responded, and 73% were unaware that the management of biosimilars and generics was not comparable. Most (84%) of those that responded were not aware that the studies required for the approval of biosimilars is different from reference biological medicines. Around two-thirds (66%) those that responded did not know of any biosimilars available in PC setting, and the 94% were also unaware of the Spanish legal framework for the management of biosimilar medicines. CONCLUSIONS: The current knowledge about biosimilars among PC physicians is low. The critical areas in need of further training include specific information on biosimilars currently available in PC setting, as well as key aspects regarding prescription, interchangeability and pharmacovigilance requirements. Six out of ten doctors do not know of any biosimilar used in PC in Spain. PMID- 29459004 TI - Does gastric conditioning decrease the incidence of cervical oesophagogastric anastomotic leakage? AB - INTRODUCTION: Oesophageal reconstruction by gastroplasty with cervical anastomosis has a higher incidence of dehiscence. The aim of the study is to analyse the incidence of anastomotic leakage in patients undergoing gastroplasty with cervical anastomosis following angiographic ischaemic conditioning of the gastric conduit. METHODS: Prospective analysis of patients who underwent gastric conditioning two weeks prior to oesophageal reconstruction, from January 2001 to January 2014. The conditioning was performed by angiographic embolization of the left and right gastric artery, and splenic artery. The main variable analysed was the incidence of anastomotic leakage in patients undergoing gastroplasty with cervical anastomosis. Secondary variables analysed were the result of the conditioning, complications arising from that procedure and in the postoperative period, and mean length of postconditioning and postoperative hospital stay. RESULTS: Gastric conditioning was indicated in 97 patients, with neoplasia being the most frequent aetiology motivating the oesophageal reconstruction (76%). 96 procedures were successfully carried out, arterial embolization was complete in 80 (83%). The morbidity rate was 13%, with no mortality. Postoperative morbidity was 45%; the most frequent complications associated with the surgery were respiratory problems. Six (7%) patients experienced cervical fistula, and all received conservative treatment. The rate of postoperative mortality was 7%. CONCLUSIONS: In our serie the incidence of anastomotic leakage in patients undergoing gastroplasty with cervical anastomosis following angiographic ischaemic conditioning is 7%. Angiographic ischaemic conditioning is a procedure with acceptable morbidity. PMID- 29459005 TI - Three Extreme Cases of Short Bowel Syndrome: STEP and Neovalves. Decision Algorithm.

AB - AIM: The relationship between glycaemic variability and painful diabetic peripheral neuropathy (PDPN) in patients with type 2 diabetes (T2D) is unclear. The aim of this study was to investigate whether variations in fasting plasma glucose (FPG), as represented by the coefficient of variation (CV), were associated with the risk of PDPN in patients with T2D. METHODS: This case control, retrospective study was conducted at a tertiary care hospital in Taiwan. We enrolled adults with T2D from January 1 through October 31, 2013. PDPN was diagnosed using the Michigan Neuropathy Screening Instrument (MNSI) and Douleur Neuropathique 4 (DN4) questionnaire. Variability in FPG was defined as a CV of visit-to-visit FPG for every 3-month interval during follow-up period before enrolment. RESULTS: A total of 2,773 patients were enrolled. One hundred patients with PDPN were randomly selected and paired with 175 consecutive patients with non-painful diabetic peripheral neuropathy and 351 patients with T2D without diabetic peripheral neuropathy, matched for age, gender, and diabetic duration. After multivariate adjustment, the FPG-CV was significantly associated with a risk of PDPN with a corresponding odds ratio of 4.08 (95% confidence interval [CI] of 1.60-10.42) and 5.49 (95% CI of 2.14-14.06) for FPG-CV in the third and fourth versus first FPG-CV quartiles, respectively, after considering glycated haemoglobin (HbA1c). CONCLUSION: Long-term variability as evaluated by FPG-CV was associated to the risk of PDPN in adults with T2D. However, further studies are needed to know whether the FPG-CV is not simply a marker of the ambient hyperglycaemia. PMID- 29459008 TI - Association of the SOD2 (rs2758339 and rs5746136) polymorphisms with the risk of heroin dependency and the SOD2 expression levels. AB - BACKGROUND: Superoxide dismutase-2 (SOD2, OMIM: 147460) is involved in the detoxification of superoxide anions. The SOD2 mRNA level is down-regulated in cells exposed to morphine. Oxidative stress plays an important role in drug dependency. The rs2758339 (A/C) is located in the vicinity of SP1 and NF-kappaB transcription element sequences and the rs5746136 (A/G) creates a new glucocorticoid receptor binding site. Taken together, it is hypothesized that these polymorphisms might be associated with the risk of heroin dependency (HD) and the SOD2 expression level. METHODS: To investigate the association between the SOD2 polymorphisms and the risk of HD, 442 heroin dependent persons and 799 healthy controls were included. This study also, consisted of 77 healthy students of Shiraz University (Iran) to investigate the association between the SOD2 polymorphisms and the gene expression level. RESULTS: The AC (OR = 0.72, 95% CI = 0.56-0.93, P = 0.013) and CC (OR = 0.64, 95% CI = 0.45-0.92, P = 0.015) genotypes of the rs2758339 were negatively associated with the risk of HD. The AA genotype of the rs5746136 increased the risk of HD (OR = 1.46, 95% CI = 1.03-2.07, P = 0.031). The AA haplotype was associated with the risk of HD (OR = 1.31, 95% CI = 1.09-1.58, P = 0.004). There was no relationship between the study genotypes (or diplotypes) and the SOD2 expression level. CONCLUSION: The rs2758339 and rs5746136 polymorphisms of the SOD2 are associated with the risk of HD but not associated with the SOD2 expression level. PMID- 29459009 TI - Characterization of metabolic network of oxalic acid biosynthesis through RNA seq data analysis of developing spikes of finger millet (Eleusine coracana): Deciphering the role of key genes involved in oxalate formation in relation to grain calcium accumulation. AB - In the present study, we identified seven major genes of oxalic acid biosynthesis pathway (SGAT, GGAT, ICL, GLO, MHAR, APO and OXO) from developing spike transcriptome of finger millet using rice as a reference. Sequence alignment of identified genes showed high similarity with their respective homolog in rice except for OXO and GLO. Transcript abundance (FPKM) reflects the higher accumulation of identified genes in GP-1 (low calcium genotype) as compared to GP 45 (high calcium genotype) which was further confirmed by qRT-PCR analysis, indicating differential oxalate formation in both genotypes. Determination of oxalic acid and tartaric acid content in developing spikes explain that higher oxalic acid content in GP-1 however, tartaric acid content was more in GP-45. Higher calcium content in GP-45 and lower oxalate accumulation may be due to the diversion of more ascorbic acid into tartaric acid and may correspond to less formation of calcium oxalate. Our results suggest that more than one pathway for oxalic acid biosynthesis might be present in finger millet with probable predominance of ascorbate-tartarate pathway rather than glyoxalate-oxalate conversion. Thus, finger millet can be use as an excellent model system for understanding more specific role of nutrients-antinutrients interactions, as evident from the present study. PMID- 29459010 TI - Plasma microRNA signature of patients with IgA nephropathy. AB - We looked for differentially expressed MicroRNAs (miRNAs) in Immunoglobulin A nephropathy (IgAN). Forty-eight miRNAs were identified through the initial screening phase (2 IgAN pools vs. 1 normal control (NC) pool) using quantitative reverse transcription polymerase chain reaction (qRT-PCR) based Exiqon panel (miRCURY-Ready-to-Use-PCR-Human-panel-I + II-V1.M). By qRT-PCR, these miRNAs were further assessed in the training (32 IgAN VS. 31 NCs) and testing stages (51 IgAN VS. 51 NCs). The renal pathological lesions of patients with IgAN were evaluated according to Lee's grading system. We discovered a plasma miRNA signature including four up-regulated miRNAs (miR-148a-3p, miR-150-5p, miR-20a-5p and miR 425-3p) and the areas under the receiver operating characteristic (ROC) curve (AUC) were 0.80 and 0.76 for the training and testing stage, respectively. The expression of the four miRNAs in IgAN grade I-II subgroups (according to Lee's grading system) was obviously higher than that in IgAN grade III-V (P < .05). In summary, the plasma expression of miR-148a-3p, miR-150-5p, miR-20a-5p and miR-425 3p were up-regulated in patients with IgAN, especially the early-stage disease. Further studies are needed to explore the roles of the four miRNAs in the pathogenesis and progression of IgAN. PMID- 29459011 TI - The effect of neoadjuvant chemotherapy on the correlation of tumor-associated macrophages with CD31 and LYVE-1. AB - Angiogenesis and lymphangiogenesis play a crucial role in tumor growth, invasion and metastasis. Tumor-associated macrophages (TAM) induce both angiogenesis and lymphangiogenesis in mouse breast cancer models and positively correlate with these processes in human breast cancer patients. Neoadjuvant chemotherapy (NAC) is a widely used therapeutic option for cancer treatment. However, the effect of NAC on the distribution of TAM within intratumoral compartments and their correlation with angiogenesis and lymphangiogenesis remained unknown. In the present study we analyzed the effect of NAC on the distribution of CD68+ and stabilin-1+ TAM in five functionally distinct areas of human breast cancer and their correlations with microvessel density (MVD) and lymphatic microvessel density (LMVD), identified by CD31 and LYVE1, respectively. We found that NAC enhances blood vessel density in soft fibrous stroma and in coarse fibrous stroma. Without NAC the amount of CD68+ TAM in gaps of ductal tumor structures positively correlate with CD31+ microvessel density in soft fibrous stroma. NAC had enhancing effect on the amount of CD68+ TAM but not stabilin-1+ TAM in soft fibrous stroma. However, no correlation between TAM and CD31+ microvessel density was identified after NAC. NAC did not enhance the lymphatic microvessel density. But after NAC stabilin-1 expressing subpopulation of TAM positively correlated with expression of LYVE-1. We hypothesized that CD68+ TAM can support tumor angiogenesis primarily before NAC, while stabilin-1+ TAM can contribute to the maintenance of lymphatic microvessel density after NAC.

PMID- 29459013 TI - The family Coriobacteriaceae is a potential contributor to the beneficial effects of Roux-en-Y gastric bypass on type 2 diabetes. AB - BACKGROUND: Changes in gut microbiota induced by bariatric surgery have been associated with metabolic benefits. OBJECTIVES: Our aim was to identify specific gut microbiota that may contribute to the improvement of type 2 diabetes (T2D) after Roux-en-Y gastric bypass (RYGB). SETTING: Laboratories of Shanghai Diabetes Institute and Shanghai Sixth People's Hospital. METHODS: Diabetic rats induced via a high-fat diet and low-dose streptozotocin administration were randomized to RYGB or sham surgery, and stool samples were collected at baseline and at postoperative week 8. The fecal microbiota was profiled using 16S ribosomal RNA gene sequencing. Additionally, we performed a case-control study of the gut microbial community profiles of T2D patients compared with those of healthy individuals via 16S ribosomal RNA gene sequencing of mucosal-luminal interface samples collected from the ascending colon during colonoscopy. RESULTS: RYGB significantly reduced the weight and improved glucose tolerance and insulin sensitivity in diabetic rats. Principal coordinate analysis showed that RYGB caused marked alterations in the gut microbiota. The RYGB group was postoperatively enriched for Bacteroidetes, Proteobacteria, Fusobacteria, and Actinobacteria, whereas the sham surgery group was enriched for Firmicutes and Verrucomicrobia. Based on the gut microbial patterns in the T2D patients, we found that the family Coriobacteriaceae within Actinobacteria might contribute to the beneficial effects of RYGB on T2D. CONCLUSIONS: RYGB significantly improves glucose metabolism and alters the gut microbiota. Moreover, the family Coriobacteriaceae may partly mediate the beneficial effects of RYGB on T2D and thus possibly contribute to the development of novel bacteria-based therapeutic approaches. PMID- 29459016 TI - Special issue: Late consequences of venous thromboembolism. PMID- 29459015 TI - Endovascular interventions decrease length of hospitalization and are cost effective in acute mesenteric ischemia. AB - OBJECTIVE: Acute mesenteric ischemia (AMI) continues to be one of the most devastating diagnoses requiring emergent vascular intervention. There is a national trend toward increased use of endovascular procedures, with improved survival for the treatment of these patients. Our aim was to evaluate whether this trend has changed the treatment of AMI and the subsequent impact on length of hospitalization and hospitalization costs. METHODS: We identified all patients admitted for AMI from the National Inpatient Sample from 2004 to 2014 who received open surgical revascularization (OPEN) or an endovascular intervention (ENDO). Primary end points included length of hospital stay and cost of hospitalization. Our secondary end points included acute kidney injury (AKI), in hospital mortality, and routine discharge. RESULTS: Among 10,381 discharges identified in the data set, 3833 (37%; 97.5% confidence interval [CI], 35%-39%) were male patients with a mean age of 69 years (range, 18-98 years); 4543 (44%; 97.5% CI, 41%-47%) patients were treated ENDO, and 5839 (56%; 97.5% CI, 53%-59%) patients were treated OPEN. Although a higher proportion of patients in the ENDO group (28%; 97.5% CI, 24%-31%) vs the OPEN group (14%; 97.5% CI, 11%-16%) had a moderate to severe Charlson Comorbidity Index (P < .0001), ENDO was associated with a lower mortality rate (12.3% [97.5% CI, 9.8%-14.8%] vs 33.1% [97.5% CI, 29.9%-36.2%]; P < .0001) and a lower mean hospitalization cost ($41,615 [97.5% CI, $38,663-$44,567] vs $60,286 [97.5% CI, $56,736-$63,836]; P < .0001). After propensity-adjusted logistic regression analysis, OPEN retained a significant association with higher mortality than ENDO (odds ratio, 3.0; 97.5% CI, 2.2-4.1) and with higher costs (mean, $9196; 97.5% CI, $3797-$14,595). Patients in the OPEN group had higher risk for AKI (P < .0001) and discharge to a skilled nursing facility (P < .0001) rather than home. CONCLUSIONS: Although the rate of ENDO continues to rise nationally, it still has not surpassed OPEN revascularization in the face of AMI. Patients treated endovascularly demonstrated one-third the rate of in-hospital mortality (odds ratio, 3.0; 97.5% CI, 2.2-4.1), an increased hazard ratio for discharge alive (hazard ratio, 2.27; 97.5% CI, 2.00-2.58), and a cost saving of $9196 (97.5% CI, $3797-$14,595) per hospitalization. Furthermore, they were less likely to develop AKI and to be discharged home after hospitalization. PMID- 29459014 TI - Regional variation in racial disparities among patients with peripheral artery disease. AB - OBJECTIVE: Prior studies identified significant racial disparities as well as regional variation in outcomes of patients with peripheral artery disease (PAD). We aimed to determine whether regional variation contributes to these racial disparities. METHODS: We identified all white or black patients who underwent infrainguinal revascularization or amputation in 15 deidentified regions of the Vascular Quality Initiative between 2003 and 2017. We excluded three regions with <100 procedures. We used multivariable linear regression, allowing clustering at the hospital level to calculate the marginal effects of race and region on adjusted 30-day mortality, major adverse limb events (MALEs), and amputation. We compared long-term outcomes between black and white patients within each region and within patients of each race treated in different regions using multivariable Cox regression. RESULTS: We identified 90,418 patients, 15,527 (17%) of whom were black. Patients underwent 31,263 bypasses, 52,462 endovascular interventions, and 6693 amputations. Black patients were younger and less likely to smoke, to have coronary artery disease, or to have chronic obstructive pulmonary disease, but they were more likely to have diabetes, limb-threatening ischemia, dialysis dependence, and hypertension and to be self-insured or on Medicaid (all P < .05). Adjusted 30-day mortality ranged from 1.2% to 2.1% across regions for white patients and 0% to 3.0% for black patients; adjusted 30-day MALE varied from 4.0% to 8.3% for white patients and 2.4% to 8.1% for black patients; and adjusted 30 day amputation rates varied from 0.3% to 1.2% for white patients and 0% to 2.1% for black patients. Black patients experienced significantly different (both higher and lower) adjusted rates of 30-day mortality and amputation than white patients did in several regions (P < .05) but not MALEs. In addition, within each racial group, we found significant variation in the adjusted rates of all outcomes between regions (all P < .01). In adjusted analyses, compared with white patients, black patients experienced consistently lower long-term mortality (hazard ratio [HR], 0.80; 95% confidence interval [CI], 0.73-0.88; P < .001) and higher rates of MALEs (HR, 1.15; 95% CI, 1.06-1.25; P < .001) and amputation (HR, 1.33; 95% CI, 1.18-1.51; P < .001), with no statistically significant variation across the regions. However, rates of all long-term outcomes varied within both racial groups across regions. CONCLUSIONS: Significant racial disparities exist in outcomes after lower extremity procedures in patients with PAD, with regional variation contributing to perioperative but not long-term outcome disparities. Underperforming regions should use these data to generate quality improvement projects, as understanding the etiology of these disparities is critical to improving the care of all patients with PAD. PMID- 29459017 TI - Poor performance in incremental shuttle walk and cardiopulmonary exercise testing predicts poor overall survival for patients undergoing esophago-gastric resection. AB - INTRODUCTION: Esophageal and gastric cancer have a poor prognosis and surgical intervention is associated with considerable morbidity, highlighting the need for careful preoperative assessment. The Incremental Shuttle Walk Test (ISWT) and Cardiopulmonary exercise testing (CPET) can assess preoperative fitness. This study aims to investigate their correlation with both postoperative respiratory complications and overall survival. PATIENTS AND METHODS: Patients were identified who underwent esophageal or gastric resections for cancer between 2010 and 2014 and had ISWT and/or CPET assessments. Tumor differentiation, stage, postoperative respiratory complications, and outcome were documented and then correlated with the results of the preoperative fitness assessments. RESULTS: Neither the ISWT result, anaerobic threshold (AT) nor VO2 Max correlated well with perioperative complications. However, ISWT (p < 0.001), AT (p < 0.001) and VO2 Max (p < 0.001) all correlated strongly with overall survival. No patient with a score of less than 350 m on ISWT survived beyond 3 years. In a subset of patients with ISWT results both pre and post chemotherapy (n = 49), those that had an improvement in result had a 19% incidence of post-operative respiratory complications compared to 45% where the result did not change or declined, though due to small numbers this only approached significance (p = 0.08). CONCLUSION: ISWT and CPET can be useful preoperative tools to predict overall survival for patients undergoing esophago-gastric resection. Furthermore, patients that improve their functional status during chemotherapy seem to do better than those where it remains static or declines. PMID- 29459018 TI - Prognostic significance of 18F-FDG PET/CT in patients with colorectal cancer liver metastases after hepatectomy. AB - INTRODUCTION: Colorectal cancer liver metastasis (CRLM) can be cured with surgery. To improve survival, optimal selection of CRLM patients should be done cautiously, which may be facilitated by preoperative [F-18] fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT). METHODS: A total of 245 patients with CRLM between February 2007 and January 2015 were retrospectively studied. All clinical variables, pathological data, and various PET/CT parameters were correlated with disease-free survival (DFS) and overall survival (OS). Metastatic tumor maximum standardized uptake value (SUVmax) and normal liver mean SUV (SUVmean) ratio was selected for group classification. RESULTS: The median DFS in months were 24.5 months and median OS were 41.7 months. Multivariate analysis found an increased risk of worse prognosis in DFS for primary colon cancer T3~T4, N2 stage, neoadjuvant chemotherapy, synchronous metastasis, multiple metastatic tumor number and metastatic tumor SUVmax/normal liver SUVmean ratio >4.3. The DFS rate of each group classified by SUV ratio was 58.1%, 39.0%, and 33.6% vs. 39.3%, 20.8%, and 15.8% at 1, 3, and 5 years (p = 0.017). Patients with multiple tumors and SUV ratio of >4.3 showed worst survival (OS rate: 74.2%, 41.5%, and 24.2%, p = 0.001 at 1, 3, and 5 years, respectively). CONCLUSIONS: PET/CT variables can be a valuable prognostic factor in patients with CRLM for the prediction of recurrence. Preoperative PET/CT may improve risk stratification and optimize outcomes of patients with CRLM. PMID- 29459019 TI - Real-time continuous glucose monitoring in adults with type 1 diabetes and impaired hypoglycaemia awareness or severe hypoglycaemia treated with multiple daily insulin injections (HypoDE): a multicentre, randomised controlled trial. AB - BACKGROUND: The effectiveness of real-time continuous glucose monitoring (rtCGM) in avoidance of hypoglycaemia among high-risk individuals with type 1 diabetes treated with multiple daily insulin injections (MDI) is unknown. We aimed to ascertain whether the incidence and severity of hypoglycaemia can be reduced through use of rtCGM in these individuals. METHODS: The HypoDE study was a 6 month, multicentre, open-label, parallel, randomised controlled trial done at 12 diabetes practices in Germany. Eligible participants had type 1 diabetes and a history of impaired hypoglycaemia awareness or severe hypoglycaemia during the previous year. All participants wore a masked rtCGM system for 28 days and were then randomly assigned to 26 weeks of unmasked rtCGM (Dexcom G5 Mobile system) or to the control group (continuing with self-monitoring of blood glucose). Block randomisation with 1:1 allocation was done centrally, with the study site as the stratifying variable. Masking of participants and study sites was not possible. Control participants wore a masked rtCGM system during the follow-up phase (weeks 22-26). The primary outcome was the baseline-adjusted number of hypoglycaemic events (defined as glucose <=3.0 mmol/L for >=20 min) during the follow-up phase. The full dataset analysis comprised participants who wore the rtCGM system during the baseline and follow-up phases. The intention-to-treat analysis comprised all randomised participants. This trial is registered with ClinicalTrials.gov, number NCT02671968. FINDINGS: Between March 4, 2016, and Jan 12, 2017, 149 participants were randomly assigned (n=74 to the control group; n=75 to the rtCGM group) and 141 completed the follow-up phase (n=66 in the control group, n=75 in the rtCGM group). The mean number of hypoglycaemic events per 28 days among participants in the rtCGM group was reduced from 10.8 (SD 10.0) to 3.5 (4.7); reductions among control participants were negligible (from 14.4 [12.4] to 13.7 [11.6]). Incidence of hypoglycaemic events decreased by 72% for participants in the rtCGM group (incidence rate ratio 0.28 [95% CI 0.20-0.39], p<0.0001). 18 serious adverse events were reported: seven in the control group, ten in the rtCGM group, and one before randomisation. No event was considered to be related to the investigational device. INTERPRETATION: Usage of rtCGM reduced the number of hypoglycaemic events in individuals with type 1 diabetes treated by MDI and with impaired hypoglycaemia awareness or severe hypoglycaemia.

PMID- 29459021 TI - Mesh versus suture repair of umbilical hernia in adults: a randomised, double blind, controlled, multicentre trial. AB - BACKGROUND: Both mesh and suture repair are used for the treatment of umbilical hernias, but for smaller umbilical hernias (diameter 1-4 cm) there is little evidence whether mesh repair would be beneficial. In this study we aimed to investigate whether use of a mesh was better in reducing recurrence compared with suture repair for smaller umbilical hernias. METHODS: We did a randomised, double blind, controlled multicentre trial in 12 hospitals (nine in the Netherlands, two in Germany, and one in Italy). Eligible participants were adults aged at least 18 years with a primary umbilical hernia of diameter 1-4 cm, and were randomly assigned (1:1) intraoperatively to either suture repair or mesh repair. In the first 3 years of the inclusion period, blocked randomisation (of non-specified size) was achieved by an envelope randomisation system; after this time computer generated randomisation was introduced. Patients, investigators, and analysts were masked to the allocated treatment, and participants were stratified by hernia size (1-2 cm and >2-4 cm). At study initiation, all surgeons were invited to training sessions to ensure they used the same standardised techniques for suture repair or mesh repair. Patients underwent physical examinations at 2 weeks, and 3, 12, and 24-30 months after the operation. The primary outcome was the rate of recurrences of the umbilical hernia after 24 months assessed in the modified intention-to-treat population by physical examination and, in case of any doubt, abdominal ultrasound. This trial is registered with ClinicalTrials.gov, number NCT00789230. FINDINGS: Between June 21, 2006, and April 16, 2014, we randomly assigned 300 patients, 150 to mesh repair and 150 to suture repair. The median follow-up was 25.1 months (IQR 15.5-33.4). After a maximum follow-up of 30 months, there were fewer recurrences in the mesh group than in the suture group (six [4%] in 146 patients vs 17 [12%] in 138 patients; 2 year actuarial estimates of recurrence 3.6% [95% CI 1.4-9.4] vs 11.4% (6.8-18.9); p=0.01, hazard ratio 0.31, 95% CI 0.12-0.80, corresponding to a number needed to treat of 12.8). The most common postoperative complications were seroma (one [<1%] in the suture group vs five [3%] in the mesh group), haematoma (two [1%] vs three [2%]), and wound infection (one [<1%] vs three [2%]). There were no anaesthetic complications or postoperative deaths. INTERPRETATION: This is the first study showing high level evidence for mesh repair in patients with small hernias of diameter 1-4 cm. Hence we suggest mesh repair should be used for operations on all patients with an umbilical hernia of this size.

AB - AIMS: Multiple myeloma (MM) is an incurable hematological cancer with a higher rate of relapse. Alterations in the function of long non-coding RNAs (lncRNAs) promote the progression and metastasis of cancer. We carry out this study to explore the expression profile of differently expressed lncRNAs in newly diagnosed MM. MAIN METHODS: The Bone marrows we analyzed were obtained from five MM and five IDA patients (serving as controls). Arraystar Human LncRNA Array V4.0 was used to profile expression of lncRNAs and mRNAs. Gene ontology (GO) and pathway analysis were utilized to understand the biological roles of differently expressed genes, while Database for Annotation, Visualization and Integrated Discovery (DAVID) was used for constructing the lncRNA-mRNA co-expression network. Quantitative polymerase chain reaction (qRT-PCR) was performed to confirm the expressions of dysregulated lncRNAs. KEY FINDINGS: Bioinformatic analysis of the lncRNA expression identified >3000 dysregulated lncRNAs (difference >= 2-fold) in MM samples. GO and pathway analysis revealed that ECM receptor and cell cycle pathway-related genes were significantly associated with MM. Four dysregulated lncRNAs were confirmed by qRT-PCR. Among them, the expression of ST3GAL6-AS1, LAMA5-AS1and RP11-175D17.3wereassociated with stage and risk status of MM. On the basis of GEO public database analysis, LAMA5-AS1 was related with an overall survival rate of MM patients. SIGNIFICANCE: These results reveal the feasible functions of lncRNAs in pathogenesis of MM. Further studies are required to explore whether these lncRNAs could serve as candidate therapeutic targets and new molecular biomarkers for MM. PMID- 29459024 TI - Effect of baicalin on GLUT4 expression and glucose uptake in myotubes of rats. AB - AIMS: Although baicalin could attenuate obesity-induced insulin resistance, the detailed mechanism of baicalin on glucose uptake has not been sufficiently explored as yet. The aim of this study was to survey if baicalin might facilitate glucose uptake and to explore its signal mechanisms in L6 myotubes. MATERIALS AND METHODS: L6 myotubes were treated with 100, 200, 400 MUM baicalin for 6 h, 12 h and 24 h in this study. Then 2-NBDG and insulin signal protein levels in myotubes of L6 cells were examined. KEY FINDINGS: We discovered that administration of baicalin enhanced GLUT4, PGC-1alpha, pP38MAPK, pAKT and pAS160 contents, as well as GLUT4 mRNA and PGC-1alpha mRNA levels in L6 myotubes. The beneficial metabolic changes elicited by baicalin were abrogated in myotubes of L6 by P38MAPK or AKT inhibitors. SIGNIFICANCE: These results suggest that baicalin promoted glucose uptake in myotubes by differential regulation on P38MAPK and AKT activity. In conclusion, these data provide insight that baicalin is a powerful and promising agent for the treament of hyperglycemia via AKT/AS160/GLUT4 and P38MAPK/PGC1alpha/GLUT4 pathway. PMID- 29459025 TI - Identification of forest cutting in managed forest of Haldwani, India using ALOS 2/PALSAR-2 SAR data. AB - Large-scale forest clear-cut identification is one of the major application of remote sensing techniques. ALOS-2/PALSAR-2 is the latest SAR satellite providing multi-polarized L-band SAR data. With increasing deforestation, it is important to assess the potential of SAR data for identifying clear-cuts in forest regions. In this research work, multi-temporal ALOS-2/PALSAR-2 SAR data and supplementary Landsat-8 optical data sets are acquired over Indian tropical forest, and SAR parameters are analysed over a progressively clear-cut Teak plantation. Sensitivity of the SAR parameters to progressive clear-cuts is estimated and found that the cross-polarized backscatter sigmaHV0 and entropy parameter H are most sensitive to both partial and complete clear-cut in forest compartments. An entropy thresholding based classification is carried out to identify clear-cut regions with a good accuracy. The study highlights the utility of SAR parameters to monitor forest clear-cuts for better forest management. PMID- 29459026 TI - Prevalence and Risk of Protein-Energy Wasting Assessed by Subjective Global Assessment in Older Adults With Advanced Chronic Kidney Disease: Results From the EQUAL Study. AB - OBJECTIVES: Prevalence and risk factors for protein-energy wasting (PEW) are poorly studied in the nondialysis, older population with advanced chronic kidney disease (CKD). Our aim was to evaluate the prevalence of PEW in advanced stage CKD patients aged greater than 65 years. Furthermore, we aimed to describe risk factors for PEW in the overall study population and among obese individuals. DESIGN: Prospective observational cohort study. METHODS: The EQUAL study, a European Quality Study on treatment in advanced chronic kidney disease, is a multicenter prospective observational cohort study in six European countries. We included patients aged >=65 years with incident glomerular filtration rate <20mL/min/1.73m2 not on dialysis attending nephrology care. PEW was assessed by 7 point Subjective Global Assessment (7-p SGA). RESULTS: In general, the study cohort (n = 1,334) was overweight (mean body mass index [BMI] 28.4 kg/m2). The majority of the patients had a normal nutritional status (SGA 6-7), 26% had moderate PEW (SGA 3-5), and less than 1% had severe PEW (SGA 1-2). Muscle wasting and loss of fat tissue were the most frequent alterations according to the SGA subscales, especially in those aged >80 years. The prevalence of PEW was higher among women, increased with age, and was higher in those with depression/dementia. PEW was the most common in those with underweight (BMI <22 kg/m2), 55% or normal weight (BMI 22-25 kg/m2), 40%. In obese individuals (BMI >30 kg/m2), 25% were diagnosed with protein wasting. Risk factors for SGA <=5 in obese people were similar to those for the overall study population. CONCLUSION: This European multicenter study shows that the prevalence of PEW is high in patients with advanced CKD aged >65 years. The risk of PEW increases substantially with age and is commonly characterized by muscle wasting. Our study suggests that focus on nutrition should start early in the follow-up of older adults with CKD.

PMID- 29459029 TI - Targeting the Architecture of Deregulated Protein Complexes in Cancer. AB - The architectures of central signaling hubs are precisely organized by static and dynamic protein-protein interactions (PPIs). Upon deregulation, these PPI platforms are capable to propagate or initiate pathophysiological signaling events. This causes the acquisition of molecular features contributing to the etiology or progression of many diseases, including cancer, where deregulated molecular interactions of signaling proteins have been best studied. The reasons for PPI-dependent reprogramming of cancer-initiating cells are manifold; in many cases, mutations perturb PPIs, enzyme activities, protein abundance, or protein localization. Consequently, the pharmaceutical targeting of PPIs promises to be of remarkable therapeutic value. For this review we have selected three key players of oncogenic signaling which are differently affected by PPI deregulation: two (the small G proteins of the RAS family and the transcription factor MYC) are considered "undruggable" using classical drug discovery approaches and in the case of the third protein discussed here, PKA, standard kinase inhibitors, may be unsuitable in the clinic. These circumstances require alternative strategies, which may lie in pharmaceutical drug interference of critical PPIs accountable for oncogenic signaling. PMID- 29459030 TI - Multifaceted Nucleolin Protein and Its Molecular Partners in Oncogenesis. AB - Discovered in 1973, nucleolin is one of the most abundant phosphoproteins of the nucleolus. The ability of nucleolin to be involved in many cellular processes is probably related to its structural organization and its capability to form many different interactions with other proteins. Many functions of nucleolin affect cellular processes involved in oncogenesis-for instance: in ribosome biogenesis; in DNA repair, remodeling, and genome stability; in cell division and cell survival; in chemokine and growth factor signaling pathways; in angiogenesis and lymphangiogenesis; in epithelial-mesenchymal transition; and in stemness. In this review, we will describe the different functions of nucleolin in oncogenesis through its interaction with other proteins. PMID- 29459031 TI - Subcellular Targeting of Nitric Oxide Synthases Mediated by Their N-Terminal Motifs. AB - From a catalytic point of view, the three mammalian nitric oxide synthases (NOSs) function in an almost identical way. The N-terminal oxygenase domain catalyzes the conversion of l-arginine to l-citrulline plus .NO in two sequential oxidation steps. Once l-arginine binds to the active site positioned above the heme moiety, two consecutive monooxygenation reactions take place. In the first step, l arginine is hydroxylated to make Nomega-hydroxy-l-arginine in a process that requires 1 molecule of NADPH and 1 molecule of O2 per mol of l-arginine reacted. In the second step, Nomega-hydroxy-l-arginine, never leaving the active site, is oxidized to .NO plus l-citrulline and 1 molecule of O2 and 0.5 molecules of NADPH are consumed. Since nitric oxide is an important signaling molecule that participates in a number of biological processes, including neurotransmission, vasodilation, and immune response, synthesis and release of .NO in vivo must be exquisitely regulated both in time and in space. Hence, NOSs have evolved introducing in their amino acid sequences subcellular targeting motifs, most of them located at their N-termini. Deletion studies performed on recombinant, purified NOSs have revealed that part of the N-terminus of all three NOS can be eliminated with the resulting mutant enzymes still being catalytically active. Likewise, NOS isoforms lacking part of their N-terminus when transfected in cells render mislocalized, active proteins. In this review we will comment on the current knowledge of these subcellular targeting signals present in nNOS, iNOS, and eNOS. PMID- 29459028 TI - Homo- and Heterodimerization of Proteins in Cell Signaling: Inhibition and Drug Design. AB - Protein dimerization controls many physiological processes in the body. Proteins form homo-, hetero-, or oligomerization in the cellular environment to regulate the cellular processes. Any deregulation of these processes may result in a disease state. Protein-protein interactions (PPIs) can be inhibited by antibodies, small molecules, or peptides, and inhibition of PPI has therapeutic value. PPI drug discovery research has steadily increased in the last decade, and a few PPI inhibitors have already reached the pharmaceutical market. Several PPI inhibitors are in clinical trials. With advancements in structural and molecular biology methods, several methods are now available to study protein homo- and heterodimerization and their inhibition by drug-like molecules. Recently developed methods to study PPI such as proximity ligation assay and enzyme fragment complementation assay that detect the PPI in the cellular environment are described with examples. At present, the methods used to design PPI inhibitors can be classified into three major groups: (1) structure-based drug design, (2) high-throughput screening, and (3) fragment-based drug design. In this chapter, we have described some of the experimental methods to study PPIs and their inhibition. Examples of homo- and heterodimers of proteins, their structural and functional aspects, and some of the inhibitors that have clinical importance are discussed. The design of PPI inhibitors of epidermal growth factor receptor heterodimers and CD2-CD58 is discussed in detail. PMID- 29459033 TI - Defining Pharmacological Targets by Analysis of Virus-Host Protein Interactions. AB - Viruses are obligate parasites that depend on cellular factors for replication. Pharmacological inhibition of essential viral proteins, mostly enzymes, is an effective therapeutic alternative in the absence of effective vaccines. However, this strategy commonly encounters drug resistance mechanisms that allow these pathogens to evade control. Due to the dependency on host factors for viral replication, pharmacological disruption of the host-pathogen protein-protein interactions (PPIs) is an important therapeutic alternative to block viral replication. In this review we discuss salient aspects of PPIs implicated in viral replication and advances in the development of small molecules that inhibit viral replication through antagonism of these interactions.

AB - Protein-protein interaction (PPI) helps in maintaining the cellular homeostasis. In particular, the homodimeric proteins play a crucial role as cell regulators. Studying the critical functions of each PPI on the living system is very challenging. The mutations in the PPIs have given birth to various diseases including many types of cancers and it has soon become the target for drug discovery. The mutations in IDH1, an asymmetric homodimer in the cytoplasm, leads to various diseases including gliomas. In this study, we have used extensive computational approaches to identify the impact of missense mutations (R132C, R132G, R132H, R132L, R132S, and V178I) occurring in the interacting region of the IDH1 homodimer. By in silico pathogenicity analysis, all the mutations occurring at the positions 132 and 178 were found to be pathogenic and neutral respectively. Furthermore, the mutants R132C and R132G were found to be responsible for increasing the stability, whereas the mutants R132H, R132L, and R132S were found to be responsible for the decrease in stability by stability analysis. R132H, R132L, and R132S mutants exhibited higher destabilization when compared to the structures of R132C and R132G mutants by molecular docking and molecular dynamics analysis.

We close with a summary of the advances responsible for making PPI inhibitors realistic targets for therapeutic intervention and brief outlook of the field. PMID- 29459035 TI - Human Interactomics: Comparative Analysis of Different Protein Interaction Resources and Construction of a Cancer Protein-Drug Bipartite Network. AB - Unraveling the protein interaction wiring that occurs in human cells as a scaffold of biological processes requires the identification of all elements that constitute such molecular interaction networks. Proteome-wide experimental studies and bioinformatic comprehensive efforts have provided reliable and updated compendiums of the human protein interactome. In this work, we present a current view of available databases of human protein-protein interactions (PPIs) that allow building protein interaction networks. We also investigate human proteins as targets of specific drugs to analyze how chemicals interact with different target proteins, placing also the study in a network relational space. Hence, we undertake a description of several major drug-target resources to provide a present perspective of the associations between human proteins and specific chemicals. The identification of molecular targets for specific drugs is a critical step to improve disease therapy. As different diseases have different biomolecular scenarios, we addressed the identification of drug-targeted genes focusing our investigations on cancer and cancer genes. So, a description of resources that provide curated compendiums of human cancer genes is presented. Cancer is a complex disease where multiple genetic changes rewire cellular networks during carcinogenesis. This indicates that cancer drug therapy needs the implementation of network-driven studies to reveal multiplex interactions between cancer genes and drugs. To make progress in this direction, in the last part of this work we provide a bipartite network of cancer genes and their drugs shown in a graph landscape that disclose the existence of specific drug-target modules. PMID- 29459036 TI - Targeting Intramembrane Protein-Protein Interactions: Novel Therapeutic Strategy of Millions Years Old. AB - Intramembrane protein-protein interactions (PPIs) are involved in transmembrane signal transduction mediated by cell surface receptors and play an important role in health and disease. Recently, receptor-specific modulatory peptides rationally designed using a general platform of transmembrane signaling, the signaling chain homooligomerization (SCHOOL) model, have been proposed to therapeutically target these interactions in a variety of serious diseases with unmet needs including cancer, sepsis, arthritis, retinopathy, and thrombosis. These peptide drug candidates use ligand-independent mechanisms of action (SCHOOL mechanisms) and demonstrate potent efficacy in vitro and in vivo. Recent studies surprisingly revealed that in order to modify and/or escape the host immune response, human viruses use similar mechanisms and modulate cell surface receptors by targeting intramembrane PPIs in a ligand-independent manner. Here, I review these intriguing mechanistic similarities and discuss how the viral strategies optimized over a billion years of the coevolution of viruses and their hosts can help to revolutionize drug discovery science and develop new, disruptive therapies. Examples are given. PMID- 29459037 TI - Preface. PMID- 29459038 TI - Molecular characterization of gene regulatory networks in primary human tracheal and bronchial epithelial cells. AB - BACKGROUND: Robust methods to culture primary airway epithelial cells were developed several decades ago and these cells provide the model of choice to investigate many diseases of the human lung. However, the molecular signature of cells from different regions of the airway epithelium has not been well characterized. METHODS: We utilize DNase-seq and RNA-seq to examine the molecular signatures of primary cells derived from human tracheal and bronchial tissues, as well as healthy and diseased (cystic fibrosis (CF)) donor lung tissue. RESULTS: Our data reveal an airway cell signature that is divergent from other epithelial cell types and from common airway epithelial cell lines. The differences between tracheal and bronchial cells are clearly evident as are common regulatory features. Only minor variation is seen between bronchial cells from healthy or CF donors. CONCLUSIONS: These data are a valuable resource for functional genomics analysis of airway epithelial tissues in human disease. PMID- 29459039 TI - Influence of Meibomian Gland Dysfunction and Friction-Related Disease on the Severity of Dry Eye. AB - PURPOSE: To evaluate the effect of meibomian gland dysfunction (MGD) and friction related disease (FRD) on the severity of dry eye disease (DED). DESIGN: Cross sectional observational study. PARTICIPANTS: This study enrolled 449 patients with DED (63 men and 386 women; mean age, 62.6+/-15.7 years [range, 21-90 years]) for analysis. METHODS: Subjective symptoms, the ocular surface, tear function, and the presence of MGD and FRD (superior limbic keratoconjunctivitis, conjunctivochalasis, and lid wiper epitheliopathy) were investigated. MAIN OUTCOME MEASURES: Schirmer value, tear film breakup time (TBUT), and keratoconjunctival score. RESULTS: We classified the participants into aqueous deficient dry eye (ADDE; n = 231 [51.4%]) and short TBUT dry eye subtype (TBUT DE; n = 109 [24.3%]) subgroups. The TBUT was shorter in patients with MGD than in those without MGD, whereas other ocular signs showed no difference (TBUT: MGD present, 1.97+/-1.02 seconds; MGD absent, 2.94+/-1.63 seconds [P < 0.001]; ADDE/MGD present, 1.94+/-1.08 seconds; ADDE/MGD absent, 2.77+/-1.61 seconds [P < 0.001]; short TBUT-DE/MGD present, 2.07+/-0.97 seconds; short TBUT-DE/MGD absent, 2.94+/-1.23 seconds [P = 0.01]). The ADDE patients with FRD showed a worse TBUT than ADDE patients without FRD (TBUT: ADDE/FRD present, 2.08+/-1.39 seconds; ADDE/FRD absent, 2.92+/-1.54 seconds; P < 0.001). CONCLUSIONS: This study showed associations between MGD, FRD, or both and ocular signs in DED. In the presence of MGD, FRD, or both, TBUT was significantly shortened regardless of the dry eye status or subtype. PMID- 29459040 TI - Interocular Axial Length and Corneal Power Differences as Predictors of Postoperative Refractive Outcomes after Cataract Surgery. AB - PURPOSE: To determine whether differences between eyes in axial length (AL) and corneal power (K) on optical biometry are predictive of refractive outcomes. DESIGN: Retrospective cohort study. PARTICIPANTS: A total of 729 patients (1458 eyes) who underwent bilateral phacoemulsification at TLC (Mississauga, Ontario, Canada) from September 2013 to August 2015. METHODS: We compared the proportion of patients having >0.5 diopters (D) of refractive error from target stratified by interocular axial length differences (IALDs) and interocular K differences (IKDs) between eyes as measured by optical biometry (IOL-Master, Carl Zeiss Meditec, Oberkochen, Germany). Analysis was repeated for 0.25 D or 1.0 D targets and for patients with uncorrected visual acuity (UCVA) >0.3 logarithm of the minimum angle of resolution (logMAR) postoperatively. MAIN OUTCOME MEASURES: Proportions, odds ratios (ORs), and corresponding 95% confidence intervals (CIs) were computed using generalized estimating equations to account for within patient correlation. RESULTS: Some 79.1% of eyes were <=0.5 D of refractive target, 47.0% were <=0.25 D, and 97.2% were <=1.0 D. The OR of having a refractive outcome >0.5 D from target for IALD cutoff of 0.2 mm was 1.4 (1.1 1.8), of 0.3 mm was 1.6 (1.2-2.1), and of 0.4 mm was 1.8 (1.3-2.5). This translates to 70.0% (63.5-75.7) within target for IALD of >=0.4 mm versus 80.7% (78.4-82.9) for <0.4 mm. For a given patient with IALD, the chance of being off target was similar for the shorter and longer eye. Eyes outside of target were twice as likely to be <-0.5 D than >0.5 D. Interocular K difference was largely not associated with prediction error, yet larger IKD-flat, steep, and average were associated with increased odds of UCVA >0.3 logMAR postoperatively. CONCLUSIONS: Interocular axial length difference of as little as >=0.2 mm is associated with a higher chance of >0.5 D of refractive error from target and worse UCVA. Interocular K difference was not associated with worse refractive error from target, although a difference of >=0.4 D was associated with worse UCVA. These cutoffs should be considered in preoperative planning and discussion with patients. Future study is required to assess whether repeating measurements, using adjunctive measurement devices, or attempting to separate true differences from artifact based on preoperative refractive characteristics reduces residual refractive error. PMID- 29459041 TI - Dexamethasone Inserts in Noninfectious Uveitis: A Single-Center Experience. AB - PURPOSE: To report the effectiveness of repeated intravitreal dexamethasone (DEX) inserts in noninfectious uveitis patients. DESIGN: Prospective, single-center, interventional clinical trial between February 2010 and March 2015. PARTICIPANTS: Patients with noninfectious uveitis with cystoid macular edema and/or vitreitis. METHODS: Patients were treated with a 700-MUg intravitreal DEX insert (Ozurdex; Allergan, Inc., Irvine, CA). Follow-up visits were scheduled 1, 3, and 6 months after injection. Best-corrected visual acuity (BCVA), central retinal thickness (CRT), vitreous haze (VH) score, intraocular pressure (IOP), and adverse events were recorded. MAIN OUTCOME MEASURES: Primary outcome was the reduction of CRT. Secondary outcome was the improvement in BCVA and reduction of VH. RESULTS: In total, 109 eyes of 76 patients received 298 DEX inserts. Fifty-two patients were women (68%). The mean age of all participants was 57 years (range, 24-88 years). More than 3 DEX inserts were injected into 44% of eyes. Mean number of injections were 1.54+/-0.5 (standard deviation [SD]), 1.98+/-0.84, and 2.46+/-1.1 over 12, 18, and 24 months, respectively. Central retinal thickness decreased significantly (P < 0.001) from 465 MUm at baseline to 318, 342, and 388 MUm after 1, 3, and 6 months, respectively. Similar trends were seen in eyes receiving a second, third, and fourth DEX insert. Patients with idiopathic uveitis and sarcoidosis benefited well from DEX inserts. The greatest overall benefit was achieved in patients with no systemic treatment and patients receiving antimetabolites and cyclosporin A. A significant VH score reduction was documented in 44% of eyes after 1 month. A gain of more than 3 lines in BCVA was recorded in 31% to 37%, 26% to 39%, and 8% to 32% of eyes after 1, 3, and 6 months, respectively. A transient rise in mean IOP after 1 month (P < 0.001) and after 3 months (P = 0.001) was seen. CONCLUSIONS: The repeated longer-term administration of DEX inserts in noninfectious uveitis patients, either alone or in combination with other therapies, led to improved CRT, BCVA, and VH. Underlying diseases and concomitant systemic therapy seem to have an impact on overall treatment benefit. Ocular complications were reversible and were managed by local treatment, with exception of cataract formation.

PMID- 29459043 TI - Is there a best approach for extracorporeal life support cannulation: a review of the extracorporeal life support organization. AB - BACKGROUND: Neurologic complications are common, and amongst the most devastating complications in pediatric patients undergoing extracorporeal life support (ECLS). Carotid artery cannulation (CAN) has been associated with an increase in these complications, thereby shaping practices to avoid this approach in most pediatric patients in which other cannulation approaches are viable. METHODS: A retrospective review of children (0-18years) in the ELSO database was undertaken from 1989 through 2013. Multivariate logistic regression analysis of rates of stroke and other neurologic complications based on cannulation technique was undertaken, adjusting for patient factors including age, underlying disease process, and severity of illness. RESULTS: A total of 30,282 ECLS runs were found in the database. CAN was associated with higher rates of stroke (5.15% vs 3.74%) and overall neurologic complications. However, when correcting for patient factors, including age, underlying disease process, and support type, CAN was not associated with an increased rate of neurologic complications or stroke (p>0.05 for both). CONCLUSION: When correcting for patient related factors CAN is not associated with an increase in stroke or neurologic compilcations. CAN should be re-examined as a cannulation technique for older pediatric patients. LEVEL OF EVIDENCE: III. PMID- 29459044 TI - Decellularized human fetal intestine as a bioscaffold for regeneration of the rabbit bladder submucosa. AB - PURPOSE: We aim to report a method to create a natural acellular scaffold from human fetal small intestine for augmentation cystoplasty in rabbits. METHODS: Fetal intestines were decellularized by immersion in a hypotonic solution. The success of this protocol was evaluated by histological analysis, scanning electron microscopy and measurement of collagen and sulfated glycosaminoglycan of the acellular tissues. Eight mature rabbits were selected and acellular scaffolds were implanted on the exposed urothelium. Urodynamic studies and cystography were performed after six months. At 14, 120 and 180days animals were sacrificed and augmented bladders were resected. RESULTS: Histological analysis revealed formation of muscular layer and blood vessels in implanted scaffolds similar to normal bladder. These findings demonstrate the effective seeding of scaffold by host bladder cells. The tissue architecture of recellularized scaffold was similar to the native bladder. CONCLUSIONS: Fetal intestine acellular matrix could be an exceptional scaffold for bladder augmentation cystoplasty and may pave the road for future studies in order to be used for clinical application. PMID- 29459045 TI - Factors associated with ultrasound-guided water enema reduction for pediatric intussusception in resource-limited setting: potential predictive role of thrombocytosis and anemia. AB - BACKGROUND/PURPOSE: Although ultrasound-guided hydrostatic reduction (USGHR) is increasingly used in managing pediatric intussusception, there is limited literature concerning its use in Malaysia. We aim to examine the experience and factors associated with the effectiveness of USGHR using water. METHODS: This is a single-center retrospective observational study in a Malaysian tertiary referral center. Children with intussusception admitted between year 2012 and 2016 were included and medical records reviewed. Factors associated with success or failure of USGHR were identified using multivariable logistic regression. RESULTS: Of the 172 cases included, 151 cases (87.8%) underwent USGHR, of whom 129 cases were successfully reduced (success rate of 85.4%). One perforation (0.7%) was reported. Age more than 3years old (aOR=7.16; 95% CI=1.07-47.94; p=0.042), anemia (aOR=10.12; 95% CI=1.12-91.35; p=0.039), thrombocytosis (aOR=11.21; 95% CI=2.06-64.33; p=0.005) and ultrasound findings of free fluid (aOR=9.39; 95% CI=1.62-54.38; p=0.012) and left-sided intussusception (aOR=8.18;95% CI=1.22-54.90, p=0.031) were independently associated with USGHR irreducibility. Symptom duration, blood in stool, vomiting and other clinical presentations, however, showed no association. CONCLUSIONS: USGHR with water is effective in the non-operative management of pediatric intussusception. Prolonged symptom duration need not necessarily preclude USGHR. The findings of anemia and thrombocytosis as independent predictors of USGHR irreducibility deserve further study. TYPE OF STUDY: Treatment study LEVEL OF EVIDENCE: III. PMID- 29459046 TI - Comparison of the biochemical and radiological criteria for lumbar disc degeneration. AB - BACKGROUND: The relationship between radiological degeneration criteria on lumbar magnetic resonance imaging (MRI) and both the keratan sulfate (KS) and chondroitin sulfate (ChS) levels was examined in disc material taken from patients undergoing lumbar disc herniation (LDH) surgery. To examine whether the biochemical and radiological degeneration criteria testing the reliability of radiological degeneration findings agreed and to evaluate the contribution of the KS/ChS ratio to disc form (protruding or extruding). METHODS: This was a prospective experimental cohort study. Using enzyme-linked immunosorbent assay, KS and ChS levels were measured in the degenerate nucleus pulposus taken from 71 patients with a diagnosis of LDH who underwent surgery. The degeneration levels and disc form (protruding or extruding) were determined according to the Pfirrmann five-stage grading system on preoperative T2-weighted lumbar MRIs. According to the Pfirrmann system, 28 patients were grade III and 43 were grade IV. The relationship between radiological criteria and the KS/ChS ratio was statistically evaluated. RESULTS: The KS levels (p=0.046) and the KS/ChS ratio (p=0.001) were significantly higher in grade IV patients than in grade III patients. However, there was no difference between the KS and ChS levels and the KS/ChS ratio when patients were classified as protruding or extruding according to their disc structure. Disc structure and biochemical degeneration indicators were not correlated. CONCLUSIONS: The KS level and the KS/ChS ratio were high in patients with marked radiological degeneration on lumbar MRI, demonstrating the sensitivity and reliability of the Pfirrmann five-stage grading system for showing radiological degeneration.

AB - Deficits in N-methyl-d-aspartate-type (NMDAR) function contribute to cognitive deficits in schizophrenia, particularly dysfunction in neuroplasticity, defined as reduced learning during training on exercises that place implicit, increasing demands on early sensory (auditory and visual) information processing. Auditory mismatch negativity (MMN) can be both a target engagement biomarker for the NMDAR and a proxy measure of neurophysiological plasticity. This review covers the evidence for using NMDAR modulator and related compounds for enhancement of cognition, with a particular focus on early auditory processing/plasticity. Compounds covered include glycine site agonists, glycine and system A-type transporter inhibitors, d-amino acid oxidase inhibitors, memantine and nicotinic alpha-7 acetylcholine receptor agonists. As opposed to daily treatment studies focusing on schizophrenia in general, intermittent, non-daily treatment combining NMDAR modulators with neuroplasticity-based paradigms, using MMN as target engagement biomarkers show promise as treatments to both remediate plasticity deficits and overall functional deficits.

AB - We performed a single-month snapshot study of the population diversity of multidrug resistant (MDR) Klebsiella pneumoniae isolates producing carbapenemases and/or extended-spectrum beta-lactamases from four major hospitals in Brazil. Isolates produced diverse ESBL (CTX-M-2, -8, -15, SHV-2), KPC-2 or both (CTX-M-2 and KPC-2), linked to specific genetic backgrounds and plasmids from a few families (IncR, IncFIIk, IncL/M) that were shared among clonal lineages within and between hospitals. A high clonal diversity was identified, among isolates from the same ST (ST11, ST15, ST101 or ST340). Diverse capsular types (n=13 K types) were identified, most of which linked to specific ST (ST11 and K27 or K64, ST101 and K17, ST340 and KL151, ST15 and K24 or ST17 and KL112). Isolates shared a common set of virulence genes (ureA, fimH, uge, wabG, mrkD, entB) and occasionally ybtS (42%) and kfuBC (18%). Our data suggest intra- and inter hospital spread of common genetic structures and international MDR K. pneumoniae clones.

AB - STUDY OBJECTIVE: This study aims to develop and validate measures of experiences of an emergency department (ED) visit suitable for use by older adults or their family members. METHODS: A cohort of patients aged 75 years and older who were discharged home was recruited at 4 EDs. At 1 week after the visit, patients or family members were interviewed by telephone to assess problems experienced at the visit. Twenty-six questions based on 6 domains of care found in the literature were developed: 16 questions were administered to all patients; 10 questions were administered to bed patients only. Scales were developed with multiple correspondence analysis. Regression analyses were used to validate the scales, using 2 validation criteria: perceived overall quality of care and willingness to return to the same ED. RESULTS: Four hundred twelve patients completed the 1-week interview, 197 ambulatory and 215 bed patients; family members responded for 75 patients. Two scales were developed, assessing personal care and communication (8 questions; alpha=.63) and waiting times (2 questions; alpha=.79). Both scales were significantly independently associated with perceived overall quality of care and willingness to return to the same ED. CONCLUSION: Two scales assessing important aspects of ED care experienced by older adults are ready for further evaluation in other settings.

PMID- 29459060 TI - Bickerstaff's brainstem encephalitis with overlapping Guillain-Barre syndrome: Usefulness of sequential nerve conduction studies. AB - Bickerstaff's brainstem encephalitis (BBE) is a rare immune-mediated disorder characterized by ophthalmoplegia, ataxia and disturbance of consciousness, which may overlap with Guillain-Barre syndrome (GBS) if there is additional limb weakness. We report a 7-month-old boy presented with ophthalmoplegia followed by a rapidly ascending paralysis of all four limbs and disturbance of consciousness. The initial impression was BBE with overlapping GBS. This was supported by sequential nerve conduction study (NCS) findings compatible with an acute inflammatory demyelinating polyneuropathy (AIDP). He received intravenous pulse methylprednisolone, intravenous immunoglobulin and plasmapharesis with complete clinical recovery after 6 weeks of illness and improved NCS findings from week 16. This is the first case of paediatric BBE with overlapping GBS with an AIDP subtype of GBS. It expands the clinical spectrum of this condition in children. Our case highlights the importance of sequential NCS in paediatric BBE with overlapping GBS for accurate electrophysiological diagnosis and prognosis particularly if the first NCS findings are not informative. PMID- 29459061 TI - Hemiconvulsion-hemiplegia-epilepsy evolving to contralateral hemi-Lennox-Gastaut like phenotype. AB - BACKGROUND: Hemiconvulsion-hemiplegia-epilepsy (HHE) involves infantile-onset acute hemiconvulsive febrile status epilepticus with subsequent unilateral cerebral atrophy and hemiparesis. Chronic epilepsy later develops, typically involving refractory focal seizures; however, the underlying pathophysiology of this epilepsy is not well understood. PATIENT: We present a boy who had a typical acute presentation of HHE at 23 months, but an unusual evolution to chronic epilepsy in which the initially unaffected hemisphere was significantly abnormal. His initial acute presentation was right-sided hemiconvulsive febrile status epilepticus, with subsequent left cerebral hemiatrophy and hemiparesis affecting the right face, arm and leg. Focal seizures began at 5 years and were refractory to medical treatment. At 9 years, video EEG monitoring showed a striking pattern of interictal slow spike-wave and paroxysmal fast activity, maximal over the right, initially unaffected, hemisphere. He had primarily focal tonic seizures involving left-sided stiffening, also appearing to originate from the right hemisphere. Following left functional hemispherotomy he became seizure-free and parents reported improved cognitive function, attention and quality of life. DISCUSSION: This boy had classic features of Lennox-Gastaut syndrome, but expressed almost exclusively over the right hemisphere, which was initially unaffected in his acute presentation of HHE. His evolution to "hemi-Lennox Gastaut-like phenotype" illustrates the importance of monitoring chronic epilepsy in patients with HHE; early surgical intervention might prevent pathologic recruitment of bilateral secondary networks leading to the refractory seizures and cognitive impairment associated with Lennox-Gastaut syndrome. PMID- 29459063 TI - Evaluation of in vitro inhibitory potential of type-I interferons and different antiviral compounds on rabies virus replication. AB - Five different compounds were tested for their in vitro inhibitory effect against RABV multiplication in mouse neuroblastoma (N2A) cell line. N2A cells were infected with the fixed RABV strain CVS-11 one hour prior to adding antivirals or their respective combinations. The infectious titre of RABV as well as the quantity of viral RNA was determined in the cell culturing medium after 48 h. All five tested compounds (mouse interferon (IFN)-alpha and -beta, ribavirin, favipiravir (T-705) and sorafenib) reduced viral replication in a concentration dependent manner: IFN-beta and sorafenib both provided 73.71% relative inhibition of viral replication in the highest non-cytotoxic concentration, while ribavirin caused 48.07%, IFN-alpha caused 44.87% and favipiravir caused 35.25% relative inhibition, respectively. When applied in combination, their antiviral activity was not synergistic, but a pronounced inhibition was detected when IFN-beta was combined with sorafenib, ribavirin, or favipiravir. The highest antiviral effect was caused by the combination of IFN-beta and sorafenib (77.19% relative inhibition). In other combinations there was an antagonistic effect detected in the reduction of viral replication. The results demonstrate that these compounds can be promising candidates for a potential combination treatment of rabies, noting that some combinations are not favourable in vitro, which makes thorough in vivo studies necessary. PMID- 29459062 TI - Cost-effectiveness of a potential vaccine candidate for Haemophilus influenzae serotype 'a'. AB - The preceding decade has witnessed the emergence of severe community-acquired acute infections caused by Haemophilus influenzae serotype a (Hia), with alarming incidence rates in North America, particularly among indigenous populations. The remarkable success of Hib conjugate vaccine over the past 20 years signify the development of an Hia vaccine candidate as a prevention measure to reduce the incidence of invasive Hia disease. However, quantifications of the long-term epidemiologic and economic impacts of vaccination are needed to inform decision on investment in Hia vaccine development and immunization programs. We sought to evaluate the cost-effectiveness of an Hia vaccine with a similar routine infant immunization schedules currently in practice for Hib in Canada. We developed and parameterized an agent-based simulation model using age-specific incidence rates reported for Nunavut, a Canadian territory with predominantly aboriginal populations. Our results, based on statistical analyses of the incremental cost effectiveness ratio, show that an Hia conjugate vaccine is highly cost-effective. Sustaining an immunization program with vaccine coverages of 77% for primary series and 93% for booster dose over a 10-year period reduces the incidence of invasive disease by 63.8% on average from 9.97 to 3.61 cases, per 100,000 population. The overall costs of disease management in year 10 are reduced by 53.4% from CDN $1.863 million (95% CI: $1.229-$2.519 M) to CDN $0.868 million (95% CI: $0.627-$1.120 M). The findings suggest an important role for a conjugate vaccine in managing Hia disease as a growing public health threat.

However, licensure usually relies on measuring induction of antibodies to PRP as a surrogate for SBA. In a phase III clinical trial we compared a PRP-conjugate vaccine using the nontoxic diphtheria toxin mutant, CRM197, as carrier protein with the licensed tetanus toxoid conjugate when administered subcutaneously as a three dose primary series in Japanese infants. As an addition to the phase III study, we have now evaluated SBA and show PRP-CRM197 induces higher levels of SBA than PRP-T four weeks after the primary series, with a statistically significant correlation with anti-PRP titers. This data confirms the superior immunogenicity of PRP-CRM197 compared with PRP-T assessed as SBA following a three-dose primary series by subcutaneous administration. Clinical trial registry: Registered on ClinicalTrials.gov (NCT01379846). PMID- 29459065 TI - Assesssing an unmet healthcare demand: A survey of immunisation among homecare patients and their caregivers. AB - Susceptibility of the homecare patient to vaccine preventable infections and their complications is high. Hospitalization of this patient group increases costs to the healthcare system. Therefore vaccination services are of great importance for protecting these patients from complications and hospitalization. We aimed to determine vaccination status of the patients receiving home care services from a tertiary hospital in Turkey and to reveal their vaccination needs. This cross sectional study was carried out in the Division of Home Care Services of Diskapi Yildirim Beyazit Training and Research Hospital in Ankara Turkey. A questionnaire Comprised of 15 questions were administered through face to face with 336 patients and their care givers. The data obtained was analyzed with descriptive statistical methods and chi-squared test was used for comparison of proportions. A total of 86.3% of the patients and 22.6% of the caregivers were older than age 65. Approximately 45% of the patients were receiving home care due to primary neurological diagnosis such as Dementia, Parkinson's disease and Cerebrovascular Accident. In addition, 78% of the patients had at least 1 additional diagnosis other than their primary diagnosis. Although immunization indications were present among all patients included in the study and at least 22% of the care providers, only 15.2% of patients and 11.3% of care providers had been recommended to receive vaccination. Among those who had been recommended to get vaccinated, 74% of patients and 77% of care givers had been administered the recommended vaccine. This finding implied that both groups were responsive to the advice for vaccination. Moreover, since the patients receiving home care are already followed-up by a healthcare team, thus these patients can be vaccinated with very little additional logistic support. PMID- 29459066 TI - Ecological thresholds of hypoxia and sedimentary H2S in coastal soft-bottom habitats: A macroinvertebrate-based assessment. AB - Ecological thresholds of dissolved oxygen (DO) and sedimentary hydrogen sulfide (H2S) for macrozoobenthos were examined during a 30-month monitoring of two stations in a highly eutrophic canal in inner Tokyo Bay, Japan. Bottom DO and H2S concentrations fluctuated seasonally, and were significantly correlated with water and sediment temperatures. Red tide-derived phytodetritus was a major source of sediment organic matters in the canal bottom, and the sediment became highly reduced and sulfidic condition in warmer months (sedimentary H2S; up to 8.5 mM). Dominant opportunistic taxa, including polychaetes and amphipods, were eliminated under low DO and high H2S conditions (i.e., population thresholds), and devastation of community structure occurred at 2.4-3.3 mg l-1 DO and 1.8-2.7 mM H2S (i.e., community thresholds). To maintain ecosystem function in anthropogenically degraded habitats and ensure colonization by macrozoobenthos throughout the year, DO and H2S levels should be maintained below these thresholds. PMID- 29459067 TI - Parthenosporophytes of the brown alga Ectocarpus siliculosus exhibit sex dependent differences in thermotolerance as well as fatty acid and sterol composition. AB - In the filamentous brown alga Ectocarpus siliculosus, male and female sex is expressed during the haploid parthenosporophyte phase of the life cycle. Here, we found that male parthenosporophytes displayed thermotolerance whereas female specimens displayed severely reduced viability at 25 degrees C and 28 degrees C. Profiling of polyunsaturated fatty acids showed that n-3 and n-6 were the predominant species in male and female parthenosporophytes, respectively, and that the n-3/n-6 fatty acid ratio was not affected by a temperature change. Both male and female parthenosporophytes contained the sterols fucosterol, cholesterol, and ergosterol, but these were present at higher levels at 10-25 degrees C in female specimens than in males. Thus, these fatty acids and sterols would be expected to make the membranes more rigid in the female compared to the male, which is opposite to the paradigm that increased rigidity confers thermotolerance. Our results suggest that the sex-dependent thermotolerance in E. siliculosus parthenosporophytes is not explained by the relationship between membrane fluidity and differences in fatty acids and sterol compositions.

AB - Biochemical and cellular responses to low concentrations of TiO2 nanoparticles (nTiO2, 1 and 10 MUg/L) and bulk (bTiO2, 10 MUg/L) were evaluated in gills, digestive gland and haemolymph of the clam Ruditapes philippinarum after1, 3 and 7 days' exposure. At 7 days, titanium content was determined in gills and digestive gland. nTiO2 significantly increased antioxidant enzyme activities in both tissues, and lipid peroxidation in digestive gland at 10 MUg/L only, and affected glutathione S-transferase activity. Slighter variations were observed in bTiO2-treated clams. A significant Ti bioaccumulation was detected in both gills and digestive gland of 10 MUg nTiO2/L-exposed clams. In haemolymph, nTiO2 affected total haemocyte count, haemocyte proliferation, haemocyte diameter and volume, and induced DNA damage. Overall, this study demonstrated that TiO2 alters most of the biomarkers measured in clams, although responses were differently modulated depending on tissues and exposure conditions, and indicated that nTiO2 can be accumulated by bivalves, suggesting a potential risk for filter-feeding animals. PMID- 29459069 TI - Otorhinolaryngology surgery analysis in Japan and Thailand: Comparing Nihon University School of Medicine with Thammasat University Faculty of Medicine. AB - BACKGROUND/OBJECTIVE: We compared the surgery data of the department of otorhinolaryngology of the university hospitals in Japan and Thailand to make each feature and the differences of both otorhinolaryngology surgeries clear. There are some medical meetings and congresses between Japan and Thailand, but so far it has not reported about the comparison of surgery data. METHODS: Retrospectively, we analyzed the surgical statistics of department of otorhinolaryngology of Nihon University Itabashi Hospital (Japan) and Thammasat University Hospital (Thailand) between 2013 and 2014. RESULTS: In Japan, there were many surgeries involving the middle ear and paranasal sinuses whereas in Thailand, tracheotomy and tonsillectomy were more frequently performed. Statistical analysis of the surgical data revealed specific tendencies in the nature of the operations performed at each university. CONCLUSION: This study revealed that there are rather differences between two hospitals' surgeries features. It was thought that it would be beneficial to both institutions to gain a deeper understanding of the areas of expertise of each university in order to foster an environment conducive to increasing future international collaborations. PMID- 29459070 TI - The influence of mechanical vibration on local and central balance control. AB - Fall prevention has an indispensable role in enhancing life expectancy and quality of life among older adults. The first step to prevent falls is to devise reliable methods to identify individuals at high fall risk. The purpose of the current study was to assess alterations in local postural muscle and central sensory balance control mechanisms due to low-frequency externally applied vibration among elders at high fall risk, in comparison with healthy controls, as a potential tool for assessing fall risk. Three groups of participants were recruited: healthy young (n = 10; age = 23 +/- 2 years), healthy elders (n = 10; age = 73 +/- 3 years), and elders at high fall risk (n = 10; age = 84 +/- 9 years). Eyes-open and eyes-closed upright standing balance performance was measured with no vibration, 30 Hz, and 40 Hz vibration of Gastrocnemius muscles. When vibratory stimulation was applied, changes in local-control performance manifested significant differences among the groups (p < 0.01). On average between conditions, we observed 97% and 92% less change among high fall risk participants when compared to healthy young and older adults, respectively. On the other hand, vibration-induced changes in the central-control performance were not significant between groups (p >= 0.19). Results suggest that local-control deficits are responsible for balance behavior alterations among elders at high fall risk and healthy individuals. This observation may be attributable to deterioration of short-latency reflexive loop in elders at high fall risk. On the other hand, we could not ascribe the balance alterations to problems related to central nervous system performance or long-latency responses. PMID- 29459071 TI - Effects of surrounding fluid on motility of hyperactivated bovine sperm. AB - Mammalian spermatozoa in organisms with internal fertilization are required to swim in the cervical and oviductal mucus, whose rheological properties differ substantially from those of water. Moreover, on the way to the oviduct, a change in sperm motility called hyperactivation may occur. In the present study, we focused on the motion characteristics of hyperactivated bovine sperm and investigated the effect of the surrounding fluid on motility. We prepared two kinds of polyacrylamide with high-viscosity non-Newtonian fluid properties, similar to the actual cervical and oviductal mucus. Using semen from Japanese cattle, we evaluated curvilinear velocity (VCL), straight-line velocity (VSL), and average path velocity (VAP). Additionally, we estimated linearity (LIN), straightness (STR), and wobble (WOB) as sperm motility parameters for several surrounding fluids. We successfully induced hyperactivation of bovine sperm in high-viscosity non-Newtonian fluid. Hyperactivation resulted in an increase in VCL and a decrease in VSL. In the high-viscosity non-Newtonian fluid, the hyperactivated sperm moved in a zig-zag pattern with regularity, different from the movement observed in a diluted solution. The increase in WOB in the non Newtonian fluid suggests that hyperactivated sperm efficiently progress along the groove that exists on the oviductal mucus wall. These results improve our understanding of the motility of bovine sperm when they undergo hyperactivation in the actual cervical and oviductal mucus. PMID- 29459072 TI - Stride length determination during overground running using a single foot-mounted inertial measurement unit. AB - From a research perspective, detailed knowledge about stride length (SL) is important for coaches, clinicians and researchers because together with stride rate it determines the speed of locomotion. Moreover, individual SL vectors represent the integrated output of different biomechanical determinants and as such provide valuable insight into the control of running gait. In recent years, several studies have tried to estimate SL using body-mounted inertial measurement units (IMUs) and have reported promising results. However, many studies have used systems based on multiple sensors or have only focused on estimating SL for walking. Here we test the concurrent validity of a single foot-mounted, 9-degree of freedom IMU to estimate SL for running. We employed a running-specific, Kalman filter based zero-velocity update (ZUPT) algorithm to calculate individual SL vectors with the IMU and compared the results to SLs that were simultaneously recorded by a 6-camera 3D motion capture system. The results showed that the analytical procedures were able to successfully identify all strides that were recorded by the camera system and that excellent levels of absolute agreement (ICC(3,1) = 0.955) existed between the two methods. The findings demonstrate that individual SL vectors can be accurately estimated with a single foot-mounted IMU when running in a controlled laboratory setting.

PMID- 29459078 TI - Biomechanical, Histologic, and Molecular Evaluation of Tendon Healing in a New Murine Model of Rotator Cuff Repair. AB - PURPOSE: To develop a clinically relevant, robust murine model of rotator cuff tendon repair to examine cellular and molecular mechanisms of healing. METHODS: Sixty C57BL/6 male mice underwent rotator cuff transection and repair using microsurgical techniques. A modified Kessler suturing technique was used prior to tendon detachment. Sutures were passed through 2 intersecting bone tunnels that were made at the tendon attachment site. Mice were sacrificed at 2 and 4 weeks with subsequent biomechanical, histologic, micro-CT, and gene expression evaluations. RESULTS: Failure forces in the 2- and 4-week groups were 36% and 75% of the intact tendon, respectively. Histologic evaluation revealed complete reattachment of the tendon with no observable gap. Healing occurred by formation of fibrovascular tissue at the tendon-bone interface, similar to larger animal models. Molecular analysis revealed gene expression consistent with gradual healing of the reattached tendon over a period of 4 weeks. Comparisons were made using 1-way analysis of variance. CONCLUSIONS: This model is distinguished by use of microsurgical suturing techniques, which provides a robust, reproducible, and economic animal model to study various aspects of rotator cuff pathology. CLINICAL RELEVANCE: Improvement of clinical outcomes of rotator cuff pathology requires in-depth understanding of the underlying cellular and molecular mechanisms of healing. This study presents a robust murine model of supraspinatus repair to serve as a standard research tool for basic and translational investigations into signaling pathways, gene expression, and the effect of biologic augmentation approaches. PMID- 29459079 TI - Anti-hypertensive treatment in peripheral artery disease. AB - Peripheral artery disease (PAD) affects more than 200 million people worldwide. Hypertension has been related to increased risk of PAD. The treatment of elevated blood pressure (BP) in these patients is indicated to lower the cardiovascular risk with a BP goal of less than 130/80mmHg. Although there is no evidence that one class of antihypertensive medication or strategy is superior for BP lowering in PAD, the use of renin-angiotensin-system (RAS) inhibitors can be effective to reduce the cardiovascular risk. Beta-blockers (BBs) are not contraindicated. In the presence of carotid atherosclerosis, calcium-channel blockers (CCBs) and angiotensin-converting-enzyme inhibitors are recommended. In fibromuscular dysplasia the treatment of choice is percutaneous renal angioplasty. In renal artery disease optimal medical therapy includes RAS inhibitors, CCBs, BBs and diuretics. PMID- 29459080 TI - Total hip arthroplasty following Girdlestone arthroplasty. AB - BACKGROUND: Complications associated with re-implantation of total hip arthroplasty (THA) after resection arthroplasty for the treatment of primary septic hip arthritis or infected THA and bipolar hemiarthroplasty (BHA) are not well-documented. Furthermore, no comparison has been made between septic arthritis (SA) and infected THA and BHA. We divided subjects into two groups for evaluation: a SA group and an infected THA or BHA group. METHODS: Nineteen hips in 19 patients (12 in the SA group, 7 in the infected THA or BHA group) with an average of 77 months of follow-up from the time of re-implantation THA were retrospectively evaluated. RESULTS: The average Japanese Orthopaedic Association hip score improved from 50 points (range, 30 to 73 points) preoperatively to 80 points (range: 64 to 96 points) at the time of the final follow-up (p < 0.01). Intra- and postoperative complications occurred in 11 cases, including intraoperative fracture in 1 hip, deep infection in 6 hips, dislocation in 7 hips, and septic loosening of acetabular component in 2 hips. Following re implantation, further surgical revision was required in four cases. Two revisions were performed for recurrent infection: one patient had recurrent dislocation of one hip, and one patient had recurrent infection and dislocation. The number of hips with relapsed infection in the infected THA or BHA group (5 hips) was significantly higher than that in the SA group (1 hip) (p < 0.05). CONCLUSIONS: Re-implantation after septic hip arthritis or infected THA or BHA was an effective treatment for improving the activity of daily life, especially the gait function. Furthermore, 94.7% of patients were free of infection at the latest follow-up. However, the rate of recurrence of infection was 31.6%, and re implantation after resection arthroplasty following infected THA or BHA led to a lower rate of infection control than that after primary SA. PMID- 29459081 TI - Changes in the diagnosis and treatment of soft tissue sarcoma in Japan, 1977 2016. AB - The treatment of soft tissue tumors has maderemarkable progress through advancements in diagnostic imaging and analysis ofsurgical materials. Changes in the treatment of soft tissue tumors are describedfrom my experience since 1977. Prior to the introduction of CT scans, radiography and angiography were the only methods for tumor localization. Wholebody CT, echography, and soft tissue radiography were introduced around 1980,and significant progress was seen in the localization of soft tissue tumors.Although the localization and diagnostic characteristics of tumors becameeasier with the introduction of MRI, radiography and ultrasound still remainedthe primary diagnostic method for soft tissue tumors. Since 1980, preoperative needle biopsy hasbecome a powerful diagnostic procedure by combining rapid cytological andpathological diagnosis at the Cancer Institute Hospital.The curative wide resection method, based on barrier theory, was an index forpreoperative planning. In addition, with the advent of evaluation methods forsurgical margins, the curability of wide resections can be discussed on acommon platform to open new possibilities in limited resection. However,because current evaluation methods for surgical margins were based onmacroscopic findings, diagnostic measures for invasive sarcomas are stillneeded in future investigations. The development of In Situ Preparation (ISP) isuseful for acquiring information that cannot be obtained with preoperativeimages as it allows for intraoperative evaluation of margins without the riskof tumor contamination, and the surgical technique could be consideredessential for limited resection. In most areas, the preservation of affectedlimbs was made possible by combining ISP with vascular reconstruction, flaptransplantation, joint arthroplasty, bone grafting, among other techniques. Inorder to improve the outcome for the treatment of sarcoma, which is a rarecancer, it is essential to consolidate facilities. PMID- 29459082 TI - Ideal screw positions for multiple screw fixation in femoral neck fractures - Study of proximal femur morphology in a Japanese population. AB - BACKGROUND: Despite the fact that multiple screw fixation is a common option of surgical treatment for femoral neck fractures, there is a paucity of precise morphological study of the femoral neck. To identify appropriate positions and spacing of hip screws for multiple-screw femoral neck fracture fixation, proximal femur morphology in Japanese patients was studied. METHOD: One hundred hips in fifty knee arthroplasty candidates were studied. Following full limb CT, defined slices were created and anatomical variables measured. RESULT: The average neck shaft angle was 126.5 degrees and the distance from the subcapital line to the subchondral bone on a line parallel to the femoral neck axis (FNA) was approximately 25 mm at the superior and inferior; borders of the femoral neck. The FNA was shown to run anterior to the femoral axis (FA). The cross section of the femoral neck forms a reverse right triangle. The height and width of the neck medullary canal were equal (approximately 25 mm), with the posterior wall closer to the femoral axis than the anterior wall. CONCLUSION: Based on these data, the anterior screw positioned just above the calcar femorale, 16 mm proximal and 27 degrees anterior to the FA, and the posterior screw positioned 12 mm proximal and 5 mm posterior to the FA is recommended. For screws inserted with a fixed angle side-plate, <=130 degrees is recommended. PMID- 29459083 TI - Therapeutic outcomes of muscular advancement by an arthroscopic-assisted modified Debeyre-Patte procedure for irreparable large and massive rotator cuff tears. AB - BACKGROUND: In cases of the large or massive rotator cuff tears, retear rates after rotator cuff repairs remain high. We introduced an arthroscopic-assisted modified Debeyre-Patte procedure which enables to decrease the tension of torn rotator cuff by sliding supraspinatus and infraspinatus laterally keeping fascia connection to the rhomboids. PURPOSE: The objective of this study was to examine the clinical outcomes and retear rates after an arthroscopic-assisted modified Debeyre-Patte procedure for irreparable large and massive rotator cuff tears. METHODS: Thirty-three rotator cuff tear patients (34 shoulders) were selected. These patients underwent arthroscopic-assisted modified Debeyre-Patte procedures and were observed postoperatively for at least 24 months. Magnetic resonance imaging (MRI) was used to evaluate the preoperative location of the torn rotator cuff stump and fatty infiltration of the muscles composing the rotator cuff, as well as the repaired rotator cuffs. Shoulder functional evaluations through the use of the Constant and Murley scores and the University of California Los Angeles (UCLA) shoulder score were compared before and after surgery, and the preoperative global fatty degeneration index (GFDI) was compared between retear and healed shoulders. RESULTS: MRI showed that 77% of shoulders were healed and 23% exhibited retear postoperatively. The mean preoperative GFDI was 1.99 among the 26 healed shoulders and 2.54 among the 8 retear shoulders (p < .05). When the Goutallier's classification was grade 3 or lower for all 3 cuff muscles for fatty infiltration, the retear rate was 14.3%. The mean Constant and Murley scores in healed and retear groups respectively improved from 34.7 +/- 15.8, 30.0 +/- 15.1 points (p = 0.47) preoperatively to 70.8 +/- 8.3, 53.9 +/- 14.0 points (p < .001), and UCLA scores in healed and retear groups from 13.8 +/- 3.9, 12.4 +/- 5.0 points (p = 0.46) preoperatively to 32.8 +/- 2.7, 28.4 +/- 3.6 points (p < .001). CONCLUSION: The clinical outcomes of healed shoulders after the arthroscopic-assisted modified Debeyre-Patte procedure were favorable. If the torn rotator cuff stump is retracted near the glenoid fossa, and the rotator cuff muscle scored Goutallier grade 3 or lower, this modified Debeyre-Patte procedure would be a viable option.

PMID- 29459084 TI - A screening method to distinguish syndromic from sporadic spinal extradural arachnoid cyst. AB - BACKGROUND: Spinal extradural arachnoid cyst (SEDAC) is a cystic lesion that protrudes into the epidural space from a small dural defect. Early diagnosis of SEDAC is important because its expansion causes neurological damage. Two types of SEDAC, syndromic and sporadic, are present. Syndromic SEDAC is inherited as a part of lymphedema-distichiasis syndrome caused by mutations in the FOXC2 gene; however, it is often mistaken as sporadic because of low penetrance. It is not reasonable to conduct a genetic testing for all SEDAC patients and their family members. The aim of this study is to establish an effective screening method to distinguish syndromic SEDAC from sporadic SEDAC. METHODS: We performed a retrospective review of medical records and imaging studies of 29 subjects who were diagnosed with SEDAC. Clinical features, family history and magnetic resonance imaging (MRI) were analyzed. Mutations in FOXC2 were examined by Sanger sequencing of the entire coding region of the genes. SEDAC having a mutation in FOXC2 gene was defined with syndromic SEDAC. RESULTS: Eleven subjects had a heterozygous mutation in FOXC2. They were all familial and hence syndromic SEDAC. Only one proband had known family history of SEDAC at diagnosis. MRI findings and physical examinations, especially eye and leg examinations, were quite useful to screen syndromic SEDAC. Physical examination often showed accompanying lymphedema and distichiasis in syndromic SEDAC. Syndromic SEDAC tended to have multiple cysts out of the thoracolumbar area. CONCLUSIONS: We established an effective screening method based on physical examinations and MRI findings. PMID- 29459086 TI - Comparative study of strong cation exchangers: Structure-related chromatographic performances. AB - Chromatographic performances are highly influenced by operational parameters. New ion exchangers have tailored matrices providing low backpressure, thereby allowing high flow velocity. By systematic frontal analysis and selectivity determination at different flow rates, we independently evaluated cation exchangers to facilitate media selection and investigated the relationship between surface modification and chromatographic performances. Structure-extended resins showed higher binding capacities compared to resins with conventional ligands directly attached to the matrix. Moreover, they maintained high capacities even with high flow velocities. Ligand accessibility was therefore largely enhanced, allowing proteins to interact and bind under harsh conditions with minimal residence/contact time. High throughput resins can be used for purification of high volume and high concentration feedstock in limited time. This results in higher productivity, and could contribute to cost reduction. In this work, we evaluated the dynamic binding capacities of various new ion exchange resins at different binding conductivities for different residence times, and observed that. PMID- 29459087 TI - Identification of five Mitragyna alkaloids in urine using liquid chromatography quadrupole/time of flight mass spectrometry. AB - Mitragyna speciosa (Kratom) is a psychoactive plant that has recently emerged as a recreational drug. Mitragyna alkaloids are not within the scope of traditional forensic toxicology screening methods, which may contribute to under-reporting. Solid phase extraction (SPE) and liquid chromatography-quadrupole/time of flight mass spectrometry (LC-Q/TOF-MS) were used to identify five alkaloids in urine. Target analytes included the two known psychoactive compounds, mitragynine and 7 hydroxymitragynine, in addition to speciociliatine, speciogynine, and paynantheine. Two deuterated internal standards (mitragynine-D3 and 7 hydroxymitragynine-D3) were employed. Using traditional reversed phase chromatography all compounds and isomers were separated in 10 min. The procedure was validated in accordance with the Scientific Working Group for Forensic Toxicology (SWGTOX) Standard Practices for Method Validation. Extraction efficiencies were 63-96% and limits of quantitation were 0.5-1 ng/mL. Precision, bias and matrix effects were all within acceptable thresholds, with the exception of 7-hydroxymitragynine, which is notably unstable and unsuitable for quantitative analysis. In this paper we present a simultaneous quantitative analytical method for mitragynine, speciociliatine, speciogynine and paynantheine, and a qualitative assay for 7-hydroxymitragynine in urine using high resolution mass spectrometry (HRMS). PMID- 29459088 TI - Purification of antibody fragments for the reduction of charge variants using cation exchange chromatography. AB - Recently, antibody fragments have been studied as therapeutic agents because they lack Fc effector function while having affinity similar to their original monoclonal antibody and can be produced using E. coli. Antibody fragments can be purified using affinity chromatography in the capture step, although they need a polishing step because of product-related impurities, mainly charge variants. Unlike monoclonal antibodies, few studies exist regarding the separation of charge variants in antibody variants. In this study, an efficient separation of charge variant method was assessed using a cation exchange chromatography resin with salt and a pH gradient. The SP ImpRes resin and pH gradient exhibited the most effective separation potency using combinations of resin and the separation method. The antibody fragment that did not undergo the charge variant separation process exhibited a difference in the tertiary structure of the protein and in vivo pharmacokinetics. However, the antibody fragment was similar to the reference protein when the charge variant separation process was performed. These results are expected to support efficient charge variant separation of antibody fragments and to be applied to the industrial production of therapeutic antibody fragments. PMID- 29459089 TI - The Role of Quantum Decoherence in FRET. AB - Resonance energy transfer has become an indispensable experimental tool for single-molecule and single-cell biophysics. Its physical underpinnings, however, are subtle: it involves a discrete jump of excitation from one molecule to another, and so we regard it as a strongly quantum-mechanical process. And yet its kinetics differ from what many of us were taught about two-state quantum systems, quantum superpositions of the states do not seem to arise, and so on. Although J. R. Oppenheimer and T. Forster navigated these subtleties successfully, it remains hard to find an elementary derivation in modern language. The key step involves acknowledging quantum decoherence. Appreciating that aspect can be helpful when we attempt to extend our understanding to situations in which Forster's original analysis is not applicable. PMID- 29459090 TI - [Thyroid carcinoma on struma ovarii: Diagnosis and treatment]. AB - Thyroid carcinoma on struma ovarii (TCSO) is a rare ovarian tumour, derivate from monodermic teratomas. It represents about 0.01% of overall ovarian tumours and 5 to 10% of struma ovarii. The diagnosis is histologic and retrospective after pelvic surgery; radiographic imaging being unspecific. Because of its rarity, the treatment of TCSO is not consensual and should be validated in multidisciplinary team involved in rare ovarian carcinoma. The first treatment is a surgical removal, with a laparoscopic approach. A fertility-conservative surgery is recommended for young women. If the tumour is unresectable and/or with metastatic spread, an adjuvant iodine 131 treatment might be proposed after thyroidectomy. Recurrence of TCSO should be taken care of as a thyroid carcinoma with tyrosine kinase inhibitor in case of progressive distant relapse, refractory to iodine 131 treatment. If the recurrence is localised, a complete surgery is the preferred option. There is no gold standard for the follow up.

AB - We present a consensus report pertaining to the improved clarity of definitions and classification of glomerular lesions in lupus nephritis that derived from a meeting of 18 members of an international nephropathology working group in Leiden, Netherlands, in 2016. Here we report detailed recommendations on issues for which we can propose adjustments based on existing evidence and current consensus opinion (phase 1). New definitions are provided for mesangial hypercellularity and for cellular, fibrocellular, and fibrous crescents. The term "endocapillary proliferation" is eliminated and the definition of endocapillary hypercellularity considered in some detail. We also eliminate the class IV-S and IV-G subdivisions of class IV lupus nephritis. The active and chronic designations for class III/IV lesions are replaced by a proposal for activity and chronicity indices that should be applied to all classes. In the activity index, we include fibrinoid necrosis as a specific descriptor. We also make recommendations on issues for which there are limited data at present and that can best be addressed in future studies (phase 2). We propose to proceed to these investigations, with clinicopathologic studies and tests of interobserver reproducibility to evaluate the applications of the proposed definitions and to classify lupus nephritis lesions. PMID- 29459093 TI - Sox11 gene disruption causes congenital anomalies of the kidney and urinary tract (CAKUT). AB - Congenital abnormalities of the kidney and the urinary tract (CAKUT) belong to the most common birth defects in human, but the molecular basis for the majority of CAKUT patients remains unknown. Here we show that the transcription factor SOX11 is a crucial regulator of kidney development. SOX11 is expressed in both mesenchymal and epithelial components of the early kidney anlagen. Deletion of Sox11 in mice causes an extension of the domain expressing Gdnf within rostral regions of the nephrogenic cord and results in duplex kidney formation. On the molecular level SOX11 directly binds and regulates a locus control region of the protocadherin B cluster. At later stages of kidney development, SOX11 becomes restricted to the intermediate segment of the developing nephron where it is required for the elongation of Henle's loop. Finally, mutation analysis in a cohort of patients suffering from CAKUT identified a series of rare SOX11 variants, one of which interferes with the transactivation capacity of the SOX11 protein. Taken together these data demonstrate a key role for SOX11 in normal kidney development and may suggest that variants in this gene predispose to CAKUT in humans. PMID- 29459094 TI - Training pharmacy technicians to administer immunizations. AB - OBJECTIVES: To evaluate the effectiveness of an immunization training program for pharmacy technicians on technicians' self-reported confidence, knowledge, and number of vaccines administered. METHODS: A one-group pre- and posttest study was conducted with certified pharmacy technicians from Albertsons and Safeway community pharmacies in Idaho. Thirty pharmacy technicians were recruited to participate in an immunization administration training program comprising a 2 hour home study and a 2-hour live training. Pharmacy technician scores on a 10 question knowledge assessment, responses on a pre- and posttraining survey, and number of immunizations administered in the 6-month period following the training were collected. RESULTS: Twenty-five pharmacy technicians completed the home study and live portions of the immunization training program. All 29 pharmacy technicians who took the home study assessment passed with greater than 70% competency on the first attempt. Technicians self-reported increased confidence with immunization skills between the pretraining survey and the posttraining survey. From December 2016 to May 2017, the technicians administered 953 immunizations with 0 adverse events reported. CONCLUSION: For the first time, pharmacy technicians have legally administered immunizations in the United States. Trained pharmacy technicians demonstrated knowledge of vaccination procedures and self-reported improved confidence in immunization skills and administered immunizations after participating in a 4-hour training program. PMID- 29459095 TI - The pharmacist's role in supporting people living with cystic fibrosis. AB - OBJECTIVES: To describe the critical need for pharmacists' involvement in outpatient care for people living with cystic fibrosis (CF). DATA SOURCES: Not applicable. SUMMARY: CF is a pulmonary condition that affects more than 30,000 children and adults in the United States and 70,000 people worldwide. Various complex medication regimens are given to patients with CF, some depending on the type of mutation they have in their CF transmembrane conductance regulator protein. With complex medication regimens and the increased number and variety of treatments that have become available, the medication use burden intensifies for individuals living with CF and their caregivers. Young people living with CF have a particularly difficult time adhering to medications and other therapies as they begin to rely less on their caregivers and assume greater medication management responsibility for their care. Adolescents report low adherence rates from about 40% to 47% for airway clearance methods and even lower for nutritional recommendations, about 16% to 20%. In inpatient settings, pharmacists have been successful in making medication use recommendations that have improved adherence for patients with CF while in the hospital. However, limited research has explored how provision of pharmacist supportive care and patient education in outpatient settings can improve medication adherence and quality of life for people living with CF. CONCLUSION: There is potential for provision of outpatient pharmacy clinical services to increase medication adherence and overall quality of care for patients with CF. Higher rates of medication adherence in patients with CF could in turn improve patient outcomes and reduce overall health care costs as a result of fewer rehospitalizations. Pharmacies can implement programs designed to provide comprehensive support services and medication management from pharmacists and staff that are trained in CF care. PMID- 29459096 TI - Objective structured clinical examination "Death Certificate" station - Computer based versus conventional exam format. AB - One option for improving the quality of medical post mortem examinations is through intensified training of medical students, especially in countries where such a requirement exists regardless of the area of specialisation. For this reason, new teaching and learning methods on this topic have recently been introduced. These new approaches include e-learning modules or SkillsLab stations; one way to objectify the resultant learning outcomes is by means of the OSCE process. However, despite offering several advantages, this examination format also requires considerable resources, in particular in regards to medical examiners. For this reason, many clinical disciplines have already implemented computer-based OSCE examination formats. This study investigates whether the conventional exam format for the OSCE forensic "Death Certificate" station could be replaced with a computer-based approach in future. For this study, 123 students completed the OSCE "Death Certificate" station, using both a computer based and conventional format, half starting with the Computer the other starting with the conventional approach in their OSCE rotation. Assignment of examination cases was random. The examination results for the two stations were compared and both overall results and the individual items of the exam checklist were analysed by means of inferential statistics. Following statistical analysis of examination cases of varying difficulty levels and correction of the repeated measures effect, the results of both examination formats appear to be comparable. Thus, in the descriptive item analysis, while there were some significant differences between the computer-based and conventional OSCE stations, these differences were not reflected in the overall results after a correction factor was applied (e.g. point deductions for assistance from the medical examiner was possible only at the conventional station). Thus, we demonstrate that the computer-based OSCE "Death Certificate" station is a cost-efficient and standardised format for examination that yields results comparable to those from a conventional format exam. Moreover, the examination results also indicate the need to optimize both the test itself (adjusting the degree of difficulty of the case vignettes) and the corresponding instructional and learning methods (including, for example, the use of computer programmes to complete the death certificate in small group formats in the SkillsLab). PMID- 29459097 TI - Evaluation of the relationship between mandibular condyle cortication and chronologic age with cone beam computed tomography. AB - PURPOSE: The aim of the present study is to evaluate the relationship between mandibular condyle cortication and chronologic age and gender via cone-beam computed tomography (CBCT) and to investigate the effectiveness of using the condylar cortication as a new method of age estimation. METHODS: CBCT images from 433 subjects aged 8 to 31 years were included in this study. The right and left condyle cortication were assessed on the sagittal plane separately for each individual by the same investigator via a new method that describes the cortication of the condyle. Type I: There is no cortication on the condyle. Type II: The bone that is on the superior surface of the condyle is seen less density than the structures around the condyle. Type III: The surface of the condyle is seen similar or higher density than the surrounding cortical areas. RESULTS: The type of the condyle cortication in the right and left mandible was similar for almost each subject and there was no statistically significant different between them (p = 0.375). When we evaluated the results without including these patients for male, Type I cortication of the condyle was seen at 14.14 +/- 2.3 years, Type II cortication of the condyle was seen at 16.11 +/- 3.18 years and Type III cortication of the condyle was seen at 19.39 +/- 3.96 years. For the female, Type I cortication of the condyle was seen at 13.01 +/- 2.16 years, Type II cortication of the condyle was seen at 15.52 +/- 2.71 years and Type III cortication of the condyle was seen at 17.95 +/- 3.13 years. The minimum age of Type III cortication was 11 and 15 years old for male and female, respectively. However, there are subjects, who are 30 year old man and 31 year old female, have no cortication as much as similar or higher than the surrounding the cortical areas. CONCLUSION: This study is the first investigation of the relationship between condyle cortication and chronologic age with CBCT in the Turkish population. The type of cortication in the right and left condyle may be different for the same individual. Chronologic age increased as the stages of the cortication process from Type I to Type III in male and female individuals, and all the stages of the cortication in the mandibular condyle of male occur later time according to female.

AB - AIMS: Proton beam therapy (PBT) is being increasingly used for craniopharyngioma. We describe our early outcome of patients treated with PBT. MATERIALS AND METHODS: Between August 2013 and July 2016, 18 patients with craniopharyngiomas were treated with 54 Cobalt Gray Equivalent (CGE) in 30 fractions over 6 weeks at our centre. The early outcome of 16 patients included in a registry study was analysed. Radiological response was assessed by RECIST criteria and the disease- and treatment-related toxicities were scored according to the CTCAE 4.0. RESULTS: All patients are alive at a median follow-up of 32.6 months (range 9.2-70.6 months) from initial diagnosis. The median age at PBT was 10.2 years (range 5.4 46.9 years). One patient progressed 8.7 months after PBT and subsequently had complete resection of the tumour. At a median follow-up of 18.4 months after PBT, five patients remained in complete remission, four in partial remission and seven with stable disease. The most common adverse effects during PBT were grade 1 (cutaneous in seven patients and fatigue in six patients). There were no treatment-related grade 3 toxicities. CONCLUSIONS: Our early results are encouraging and comparable with the limited literature on PBT for craniopharyngioma.

AB - AIMS: To identify symptom clusters and predisposing factors associated with long term symptoms and health-related quality of life after radiotherapy in men with prostate cancer. MATERIALS AND METHODS: Patient-reported outcomes (PROs) data from the Medical Research Council RT01 radiotherapy with neoadjuvant androgen deprivation therapy trial of 843 patients were used. PROs were collected over 5 years with the University of California, Los Angeles Prostate Cancer Index (UCLA PCI) and the 36 item Short-Form Health Survey (SF-36). Symptom clusters were explored using hierarchical cluster analysis. The association of treatment dose, baseline patient characteristics and early symptom clusters with the change in severity of PROs over 3 years was investigated with multivariate linear mixed effects models. RESULTS: Seven symptom clusters of three or more symptoms were identified. The clusters were stable over time. The longitudinal profiles of symptom clusters showed the onset of acute symptoms during treatment for all symptom clusters and significant recovery by 6 months. Some clusters, such as physical health and sexual function, were adversely affected more than others by androgen deprivation therapy, and were less likely to return to pretreatment levels over time. Older age was significantly associated with decreased long-term physical function, physical health and sexual function (P < 0.001). Both baseline and acute symptom clusters were significant antecedents for impaired function and health-related quality of life at 3 years. CONCLUSIONS: Men with poorer physical function and health before or during treatment were more likely to report poorer PROs at year 3. Early assessment using PROs and lifestyle interventions should be used to identify those with higher needs and provide targeted rehabilitation and symptom management. PMID- 29459104 TI - Use of microalgae to recycle nutrients in aqueous phase derived from hydrothermal liquefaction process. AB - Hydrothermal liquefaction (HTL) of microalgae biomass generates an aqueous phase (AP) byproduct with limited energy value. Recycling the AP solution as a source of nutrients for microalgae cultivation provides an opportunity for a cost effective production of HTL based biofuel and algal biomass feedstock for HTL, allowing a closed-loop biofuel production in microalgae HTL biofuel system. This paper aims to provide a comprehensive overview of characteristics of AP and its nutrients recycling for algae production. Inhibitory effects resulted from the toxic compounds in AP and alleviation strategies are discussed.

AB - To meet the CO2 emission reduction targets, carbon dioxide capture and utilization (CCU) comes as an evolve technology. CCU concept is turning into a feedstock and technologies have been developed for transformation of CO2 into useful organic products. At industrial scale, utilization of CO2 as raw material is not much significant as compare to its abundance. Mechanisms in nature have evolved for carbon concentration, fixation and utilization. Assimilation and subsequent conversion of CO2 into complex molecules are performed by the photosynthetic and chemolithotrophic organisms. In the last three decades, substantial research is carry out to discover chemical and biological conversion of CO2 in various synthetic and biological materials, such as carboxylic acids, esters, lactones, polymer biodiesel, bio-plastics, bio-alcohols, exopolysaccharides. This review presents an over view of catalytic transformation of CO2 into biofuels and biomaterials by chemical and biological methods. PMID- 29459106 TI - Building Sangha in the American Healthcare Setting for Persons with Chronic Disease. AB - BACKGROUND: For persons with chronic disease, participation in meditation interventions can reduce anxiety, depression, and chronic disease symptoms in a dose dependent fashion. Unfortunately, information about how to support long-term participation in such an intervention is lacking. Therefore, a recent discovery of persons with chronic lung disease who have maintained a self-led meditation group for more than four years created an opportunity to analyze experiences, meanings and relationship dynamics of this community-based meditation group. METHODS: A focused ethnography was conducted using the following techniques: participant observation of four group meditation sessions, semi-structured interviews of six group participants, the interviewer's reflective practice and collection of demographic information. Analysis of transcribed audio-recordings followed an iterative approach. RESULTS: Findings highlighted the inclusive nature of the group sessions that supported meditation practice through the processing of ancient wisdom traditions similar to a traditional Sangha. Reflecting the current culture of non-affiliation, the group often moved beyond religious teachings to use the environment, literature and pop culture representations to teach wisdom traditions. Data analysis revealed that the holistic group characteristics of wisdom circling, non-Stopping, organic way finding and sacred space were supported by identifiable yet inseparable individual and group actions. This holistic pattern is best described through the metaphor of flocking birds. CONCLUSIONS: This self-led group supports long term meditation practice and provides a sense of eudemonic well-being for a diverse group of individuals in an accessible community setting. PMID- 29459107 TI - Analysis of economic and social costs of adverse events associated with blood transfusions in Spain. AB - OBJECTIVE: To calculate, for the first time, the direct and social costs of transfusion-related adverse events in order to include them in the National Healthcare System's budget, calculation and studies. In Spain more than 1,500 patients yearly are diagnosed with such adverse events. METHOD: Blood transfusion related adverse events recorded yearly in Spanish haemovigilance reports were studied retrospectively (2010-2015). The adverse events were coded according to the classification of Diagnosis-Related Groups. The direct healthcare costs were obtained from public information sources. The productivity loss (social cost) associated with adverse events was calculated using the human capital and hedonic salary methodologies. RESULTS: In 2015, 1,588 patients had adverse events that resulted in direct health care costs (4,568,914?) and social costs due to hospitalization (200,724?). Three adverse reactions resulted in patient death (at a social cost of 1,364,805?). In total, the cost of blood transfusion-related adverse events was 6,134,443? in Spain. For the period 2010-2015: the trends show a reduction in the total amount of transfusions (2 vs. 1.91M?; -4.4%). The number of adverse events increased (822 vs. 1,588; +93%), as well as their related direct healthcare cost (3.22 vs. 4.57M?; +42%) and the social cost of hospitalization (110 vs 200M?; +83%). Mortality costs decreased (2.65 vs. 1.36M?; -48%). DISCUSSION: This is the first time that the costs of post-transfusion adverse events have been calculated in Spain. These new figures and trends should be taken into consideration in any cost-effectiveness study or trial of new surgical techniques or sanitary policies that influence blood transfusion activities.

AB - OBJECTIVE: Minimally invasive mitral valve repair may be associated with prolonged cardioplegic arrest times and ischemic reperfusion injury. Intravenous (propofol) and volatile (sevoflurane) anesthesia are used routinely during cardiac surgery and are thought to provide cardioprotection; however, the individual contribution of each regimen to cardioprotection is unknown. Therefore, the authors sought to compare the cardioprotective effects of propofol and sevoflurane anesthesia in patients undergoing minimally invasive mitral valve repair. DESIGN: A single-center single-blind randomized controlled trial. SETTING: A specialized regional cardiac surgery center in Italy. PARTICIPANTS: The study enrolled 62 adults undergoing elective isolated minimally invasive mitral valve repair for degenerative disease. Exclusion criteria included secondary mitral regurgitation, previously treated coronary artery disease, diabetes mellitus, chronic renal failure requiring dialysis, atrial fibrillation, and documented allergy to either propofol or sevoflurane. INTERVENTIONS: All patients received video-assisted minimally invasive right minithoracotomy. Patients were randomized to receive propofol or sevoflurane anesthesia in a 1:1 ratio. MEASUREMENTS AND MAIN RESULTS: Cardiac troponin I release was measured over the first 72 hours postoperatively. Operative, cross-clamp, and total bypass times were similar between groups. Cardiac troponin I release was reduced nonsignificantly in the propofol group (p = 0.62), and peak troponin I release was correlated with cross-clamp time in both groups. There were no differences in terms of intraoperative lactate release and blood pH between groups. CONCLUSION: Propofol and sevoflurane anesthesia were associated with similar degrees of myocardial injury, indicating comparable cardioprotection. Myocardial injury was related directly to the duration of cardioplegic arrest. PMID- 29459112 TI - How to Measure Tissue Oxygenation Using Near-Infrared Spectroscopy in a Patient With Alkaptonuria.

PMID- 29459114 TI - High dietary glycemic load was associated with the presence and burden of cerebral small vessel diseases in acute ischemic stroke patients. AB - Cerebral small vessel diseases (SVDs) are closely associated with stroke. Elevated postprandial blood glucose is also an important risk factor for stroke. Dietary glycemic load (GL) and glycemic index (GI) are frequently used as markers of postprandial blood glucose response used as an estimator of the overall glycemic effect of the diet. We hypothesized that high dietary GL or GI will be associated with presence of cerebral SVDs in patients with acute ischemic stroke. We prospectively included 263 patients who had experienced first-ever symptomatic cerebral infarction within 7 days after symptom onset and who submitted a fully filled-in semi-quantitative food frequency questionnaire. The dietary GL and GI values of food were constructed through an International table based on glucose. The presence and burden of high-grade white matter hyperintensities (HWMHs), cerebral microbleeds (CMBs), high-grade perivascular spaces (HPVSs) and asymptomatic lacunar infarctions (ALIs) were investigated. Mean age of the total patient population was 65.4 +/- 11.7 years. After adjusting for age, sex, and variables with P < .1 in univariate analysis, high dietary GL was independently associated with an increased risk of presence of HWMHs (odds ratio (OR) (95% confidence interval (CI)) comparing the top quartile with the bottom quartile: 3.31 (1.37-7.98); P (for trend) = .006), CMBs (OR (95% CI): 3.06 (1.06-8.85); P = .032), PVSs (OR (95% CI): 3.24 (0.75-13.90); P = .039), and ALIs (OR (95% CI): 2.44 (0.97-6.13); P = .037). In conclusion, high dietary GL was associated with the presence and burden of cerebral SVDs in patients with acute cerebral infarction. PMID- 29459115 TI - Inflammatory bowel disease and risk of Parkinson's disease in Medicare beneficiaries. AB - INTRODUCTION: Gastrointestinal (GI) dysfunction precedes the motor symptoms of Parkinson's disease (PD) by several years. PD patients have abnormal aggregation of intestinal alpha-synuclein, the accumulation of which may be promoted by inflammation. The relationship between intestinal alpha-synuclein aggregates and central nervous system neuropathology is unknown. Recently, we observed a possible inverse association between inflammatory bowel disease (IBD) and PD as part of a predictive model of PD. Therefore, the objective of this study was to examine the relationship between PD risk and IBD and IBD-associated conditions and treatment. METHODS: Using a case-control design, we identified 89,790 newly diagnosed PD cases and 118,095 population-based controls >65 years of age using comprehensive Medicare data from 2004-2009 including detailed claims data. We classified IBD using International Classification of Diseases version 9 (ICD-9) diagnosis codes. We used logistic regression to calculate odds ratios (ORs) and 95% confidence intervals (CIs) to evaluate the association between PD and IBD. Covariates included age, sex, race/ethnicity, smoking, Elixhauser comorbidities, and health care use. RESULTS: PD was inversely associated with IBD overall (OR = 0.85, 95% CI 0.80-0.91) and with both Crohn's disease (OR = 0.83, 95% CI 0.74 0.93) and ulcerative colitis (OR = 0.88, 95% CI 0.82-0.96). Among beneficiaries with >=2 ICD-9 codes for IBD, there was an inverse dose-response association between number of IBD ICD-9 codes, as a potential proxy for IBD severity, and PD (p-for-trend = 0.006). CONCLUSION: IBD is associated with a lower risk of developing PD. PMID- 29459116 TI - Can aquatic macrophytes be biofilters for gadolinium based contrasting agents? AB - The use of gadolinium-based contrasting agents (GBCA) is increasing because of the intensive usage of these agents in magnetic resonance imaging (MRI). Waste water treatment does not reduce anthropogenic Gd-concentration significantly. Anomalous Gd-concentration in surface waters have been reported worldwide. However, removal of GBCA-s by aquatic macrophytes has still hardly been investigated. Four aquatic plant species (Lemna gibba, Ceratophyllum demersum, Elodea nuttallii, E. canadensis) were investigated as potential biological filters for removal of commonly used but structurally different GBCA-s (Omniscan, Dotarem) from water. These plant species are known to accumulate heavy metals and are used for removing pollutants in constructed wetlands. The Gd uptake and release of the plants was examined under laboratory conditions. Concentration dependent infiltration of Gd into the body of the macrophytes was measured, however significant bioaccumulation was not observed. The tissue concentration of Gd reached its maximum value between day one and four in L. gibba and C. demersum, respectively, and its volume was significantly higher in C. demersum than in L. gibba. In C. demersum, the open-chain ligand Omniscan causes two-times higher tissue Gd concentration than the macrocyclic ligand Dotarem. Gadolinium was released from Gd-treated duckweeds into the water as they were grown further in Gd-free nutrient solution. Tissue Gd concentration dropped by 50% in duckweed treated by Omniscan and by Dotarem within 1.9 and 2.9 days respectively. None of the macrophytes had a significant impact on the Gd concentration of water in low and medium concentration levels (1-256 MUg L-1). Biofiltration of GBCA-s by common macrophytes could not be detected in our experiments. Therefore it seems that in constructed wetlands, aquatic plants are not able to reduce the concentration of GBCA-s in the water. Furthermore there is a low risk that these plants cause the accumulation of anthropogenic Gd in the food chain. PMID- 29459117 TI - Improving water quality using settleable microalga Ettlia sp. and the bacterial community in freshwater recirculating aquaculture system of Danio rerio. AB - A highly settleable microalga, Ettlia sp., was applied to a freshwater recirculating aquaculture system (RAS) of Danio rerio to improve the treatment of nitrogenous compounds. The growth characteristics of the microalgae, water quality parameters, and bacterial communities were monitored for 73 days. In the treatment RAS, the inoculated Ettlia sp. grew up to 1.26 g/L and dominated (>99%) throughout the experiment, whereas naturally occurring microalgae grew to 0.57 g/L in the control RAS. The nitrate, nitrite, and ammonium concentrations in the treatment RAS were reduced by 50.1%, 73.3%, and 24.2%, respectively, compared to the control RAS. A bacterial community analysis showed that Rhodospirillales, Phycisphaerae, Chlorobiales, and Burkholderiales were the major bacterial groups in the later phase of the treatment RAS. Meanwhile, a network analysis among the Ettlia sp., bacterial groups, and environmental parameters, revealed that the bacterial groups played key roles in both water quality improvement and Ettlia sp. growth. In conclusion, the inoculation and growth of the Ettlia sp. and its associated bacteria in the RAS produced beneficial effects on the water quality by reducing the nitrogenous compounds and providing a favorable environment for certain bacterial groups to further improve water quality. PMID- 29459118 TI - Aqueous photodegradation of substituted chlorobenzenes: Kinetics, carbon isotope fractionation, and reaction mechanisms. AB - Substituted chlorobenzenes are the basic substructure of many surface water contaminants. In this study, the isotope fractionation and reaction mechanisms involved during the aqueous direct and indirect photodegradation of CH3-, Cl-, and NO2- substituted chlorobenzenes were investigated in laboratory experiments. Only 4-nitrochlorobenzene showed slow but isotopically fractionating direct photolysis. During indirect photodegradation using UV/H2O2-generated OH radicals, the pseudo first-order reaction rate constants increased in the order of the NO2- < Cl- < CH3- substituted chlorobenzenes. The most pronounced carbon enrichment factors were observed for nitrochlorobenzenes (up to -4.8 +/- 0.50/00), whereas the lowest were for chlorotoluenes (<=-1.0 +/- 0.10/00). As the substituents became more electron-withdrawing, the activation energy barrier increased, leading to slower reaction rates, and the transition state changed to a more symmetrical or less reactant-like structure, resulting in larger apparent kinetic isotope effects. The results suggest that the rate-determining step in the reaction with OH radicals was the addition of the electrophile to the benzene ring. Even though further research is needed to quantify isotope fractionation during other transformation processes, these results showed evidence that compound specific isotope analysis can be used as a diagnostic tool for the fate of substituted chlorobenzenes in water. PMID- 29459119 TI - Role of the Nrf2-ARE pathway in perfluorooctanoic acid (PFOA)-induced hepatotoxicity in Rana nigromaculata. AB - Perfluorooctanoic acid (PFOA) is widely distributed in various environmental media and is toxic to organisms. This study demonstrated that PFOA induces hepatotoxicity in the frog and evaluated the role of CYP3A and the Nrf2-ARE signaling pathway in regulating responses to PFOA-induced hepatotoxicity. Rana nigromaculata were exposed to 0, 0.01, 0.1, 0.5, or 1 mg/L PFOA solutions in a static-renewal system for 14 days. Liver tissue samples were collected 24 h after the last treatment. Hepatic histology was observed by HE staining and transmission electron microscopy. The oxidative stress levels in the liver were measured. The expression levels of CYP3A, Nrf2, NQO1, and HO-1 mRNA were measured by quantitative reverse transcription-polymerase chain reaction. PFOA-treated frog liver tissue exhibited diffuse cell borders, cytoplasmic vacuolization, broken nuclei, nuclear chromatin margination, and swollen mitochondria. In addition, the livers of PFOA-treated frogs showed a significantly elevated content of reactive oxygen species, malondialdehyde, glutathione and glutathione S-transferase activity compared to the livers of control frogs. However, the glutathione peroxidase activities concomitantly decreased in PFOA-treated frogs compared to those in the control group. Furthermore, compared with control frogs, the expression levels of CYP3A, Nrf2, and NQO1 mRNA significantly increased in PFOA-treated frogs. HO-1 mRNA expression remarkably increased only in groups treated with 0.5 or 1 mg/L PFOA. Our results indicate that PFOA induces hepatotoxicity in a dose-dependent manner. Furthermore, the results of the comparison analysis between different gender groups illustrated that PFOA is more toxic to female frogs than male frogs. Our results demonstrated that PFOA causes liver damage and that CYP3A enhances PFOA-induced female frogs hepatotoxicity are more virulent than male through biotransformation, and the activation of the Nrf2 ARE pathway is induced to protect against hepatotoxicity in Rana nigromaculata, all of which provide the scientific basis for the protection of amphibians against environmental contaminants. PMID- 29459120 TI - Immediate Effects of Core Stabilization Exercise on beta-Endorphin and Cortisol Levels Among Patients With Chronic Nonspecific Low Back Pain: A Randomized Crossover Design. AB - OBJECTIVE: The main objective of the study was to measure the levels of plasma beta-endorphin (PB) and plasma cortisol (PC) under lumbar core stabilization exercise (LCSE), placebo and control conditions in patients with chronic nonspecific low back pain. METHODS: Twenty-four participants with chronic nonspecific low back pain participated in a randomized, placebo-controlled, crossover design study. There were 3 experimental exercise conditions: control condition (positioning in crook lying and rest), placebo condition (passive cycling in crook lying using automatic cycler), and LCSE on a Pilates device tested with a 48-hour interval between sessions by concealed randomization. A blood sample was collected before and after the exercise conditions. Plasma beta endorphin and PC were measured through enzyme-linked immunosorbent assay and electrochemiluminescence in a Cobas E411 auto analyzer. RESULTS: A significant difference in PB level was identified before and after the LCSE condition (P < .05), whereas no significant differences were noted in control and placebo exercise conditions. Also, the trend of elevation of PB under the LCSE was significantly different compared with the placebo and control conditions (P < .01). In contrast, the PC level remained unchanged in all 3 conditions. CONCLUSION: The findings of this study indicate that LCSE could possibly influence PB but not PC level among patients with chronic nonspecific low back pain. The mechanism of action of the pain-relieving effect of LCSE might be related to an endogenous opioid mechanism as part of its effects and might not be involved with a stress-induced analgesia mechanism. PMID- 29459121 TI - Effect of Adding Interferential Current in an Exercise and Manual Therapy Program for Patients With Unilateral Shoulder Impingement Syndrome: A Randomized Clinical Trial. AB - OBJECTIVE: The purpose of this study was to measure the additional effect of adding interferential current (IFC) to an exercise and manual therapy program for patients with unilateral shoulder impingement syndrome. METHODS: Forty-five participants were randomly assigned to group 1 (exercise and manual therapy), group 2 (exercise and manual therapy + IFC), or group 3 (exercise and manual therapy + placebo ultrasound). Individuals participated in 16 treatment sessions, twice a week for 8 weeks. The primary outcome of the study was total score of the Shoulder Pain and Disability Index (SPADI). The secondary outcomes were the pain and disability subscales of SPADI, Numeric Rating Scale, and Pain-Related Self Statement Scale. Adjusted between-group mean differences (MDs) and 95% confidence intervals (CIs) were calculated using linear mixed models. RESULTS: After 16 treatment sessions, statistically significant but not clinically important differences were identified in favor of the exercise and manual therapy program alone in the SPADI-total (group 1 vs group 2, MD 11.12 points, 95% CI 5.90-16.35; group 1 vs group 3, MD 13.43 points, 95% CI 8.21-18.65). Similar results were identified for secondary outcomes. CONCLUSION: The addition of IFC does not generate greater clinical effects in an exercise and manual therapy program for individuals with unilateral shoulder impingement syndrome. PMID- 29459122 TI - The Association Among Overweight, Obesity, and Low Back Pain in U.S. Adults: A Cross-Sectional Study of the 2015 National Health Interview Survey. AB - OBJECTIVE: The purpose of this study was to explore the association between obesity (via body mass index [BMI]) and presence of low back pain (LBP) in a representative sample of US adults, aged >=18 years. METHODS: This cross sectional study used data from 32 060 respondents to the 2015 National Health Interview Survey. Body mass index (kg/m2) was calculated using reported height and weight and expressed as normal weight (<25 kg/m2), overweight (25 to <30 kg/m2), or obese (>=30 kg/m2); 3-month prevalence of reported LBP was the targeted outcome. Weighted univariate and multivariable logistic regression (adjusting for age, sex, race/ethnicity, education, and leisure-time physical activity) were performed. Interaction by sex and race/ethnicity was also explored. RESULTS: Findings suggest a statistically significant association between BMI categories and LBP. The adjusted odds ratios (95% confidence interval) of LBP in overweight and obese participants were higher than those in normal weight participants: 1.21 (1.11-1.32) and 1.55 (1.44-1.67), respectively. Both sex and race/ethnicity statistically significantly modified the association between BMI and LBP. Compared with normal weight white men (reference), odds ratios (95% confidence interval) of LBP were higher among obese white men, obese white women, and obese nonwhite women (1.28 [1.10, 1.48], 1.58 [1.36, 1.84], and 1.36 [1.16, 1.60], respectively), and lower in overweight, nonwhite men, and normal weight nonwhite men and women (0.80 [0.68, 0.94], 0.62 [0.51, 0.76], and 0.73 [0.61, 0.87], respectively). CONCLUSION: Overweight and obesity were associated with increased odds of LBP. However, the measures of associations varied in magnitude and direction by race and sex groups. PMID- 29459123 TI - High-pressure balloon valvuloplasty for severe pulmonary valve stenosis: a prospective observational pilot study in 25 dogs. AB - OBJECTIVES: We aimed to evaluate safety and efficacy of high-pressure balloon valvuloplasty (HPBVP) for treatment of canine severe pulmonary valve stenosis (PS). A secondary aim was to provide pre-procedure predictors of success. ANIMALS: Twenty-five dogs. METHODS: Prospective observational study. Dogs with severe PS (echocardiographically derived trans-pulmonary peak/maximum pressure gradient (EDPG) >=80 mmHg) were recruited. All dogs underwent echocardiography before and 20-24hrs after HPBVP using a high-pressure balloon with rated burst pressures ranging from 12 to 18 ATM. Procedural success was defined as a post HPBVP EDPG reduction of >=50% or reduction into at least the moderate category of PS (50-79 mmHg). Optimal result was defined as a post-procedural EDPG <=30 mmHg. RESULTS: Initial median (IQR) EDPG for all dogs was 96 (88, 127) mmHg with a post operative median of 48 (36, 65) mmHg. The median EDPG reduction provided by HPBVP was 63% (39, 68); procedural success rate was 92% (23 dogs). Optimal results were achieved in 56% (14 dogs). There were no significant correlations between EDPG reduction and valve morphology (Type A and Type B) or severity of right ventricular hypertrophy. Pulmonary valve annulus diameter was the only echocardiographic variable that was significantly correlated to EDPG reduction (p = 0.02; r = -0.46). No dog experienced any anesthetic or surgical complications, and all patients survived the procedure. CONCLUSIONS: In this cohort of 25 dogs with severe PS, HPBVP was safe and effective. The procedural success rate and high number of optimal results achieved with HPBVP suggest future randomized controlled trials comparing HPBVP to conventional valvuloplasty are warranted. PMID- 29459124 TI - Left atrial deformation and phasic function determined by two-dimensional speckle tracking echocardiography in dogs with myxomatous mitral valve disease. AB - INTRODUCTION: Left atrial (LA) function can provide useful information in dogs with myxomatous mitral valve disease (MMVD). Recently, we have demonstrated the feasibility of measuring LA longitudinal deformation using speckle-tracking echocardiography (STE) to estimate LA function in healthy dogs. Whether LA strain and strain rate variables provide additional information about LA function and clinical cardiac status in dogs with MMVD remains unexplored. ANIMALS: Ninety-six client-owned dogs of different breeds with MMVD were prospectively enrolled. METHODS: LA longitudinal deformation was evaluated in each dog by STE and different STE variables were used to assess LA function. RESULTS: No STE variables differed between American College of Veterinary Internal Medicine Stage B1 and B2 dogs but were lower in Stage C dogs. Peak atrial longitudinal average strain < 27.9%, left-atrial-to-aortic ratio > 2.2 and peak atrial contraction average strain < 7.25% discriminated symptomatic MMVD dogs by receiver operating characteristic analysis with sensitivity and specificity of 100% and 100% (95% confidence interval [CI] 91-100%), 92% (95% CI 78-98%) and 98% (95% CI 87-100%), 100% (95% CI 91-100%) and 95% (95% CI 83-99%), respectively. In 12 dogs with similar left-atrial-to-aortic ratio, peak atrial longitudinal average strain and peak atrial contraction average strain differentiated dogs with subclinical disease from those with congestive heart failure (CHF). CONCLUSION: Dogs with MMVD in CHF appear to have lower LA longitudinal strain and strain rate variables compared with dogs with subclinical disease. Further studies are needed to establish if our initial findings can provide useful information for the diagnosis, treatment, and prognosis of dogs with MMVD.

AB - INTRODUCTION: The fight against smoking is a major challenge for public health in Reunion Island. This French overseas department knows considerable social inequalities and so there is a possibility of free access to nicotine substitution among disadvantaged patients. The objective was to describe the social characteristics, the level of addiction to smoking and the actual level of smoking cessation at 18 months of tobacco-smoking patients from Reunion who consulted in 2014. METHODS: It was an observational, retrospective, monocentric study carried out in the addictology service in the teaching hospital in Saint Denis, Reunion Island. Inclusion of patients over the year 2014 who were mono dependent on tobacco and who were consulting for the first time in order to give up smoking. RESULTS: 122 patients were included, 51 % of women, of an average age of 47.5 years. The rate of smoking cessation at a year and a half was 23 %. There was no significant difference concerning smoking cessation according to the patient's level of addiction, the educational level, the profession or the level of confidence when stopping. DISCUSSION: The proportion of patients who had given up at a year and a half in our study was comparable to the data found in international literature. The impact of free access to nicotine substitution on smoking cessation could not be estimated. PMID- 29459128 TI - Clinical viability of single implant-retained mandibular overdentures: a systematic review and meta-analysis. AB - The aim of this meta-analysis was to verify the clinical viability of single implant-retained mandibular overdentures (SIMO). An electronic search of the PubMed and Cochrane databases was performed (end date July 2017); this was supplemented by a manual search of the literature. Only prospective clinical trials and randomized controlled trials (RCTs) that evaluated SIMO with a minimum follow-up of 12 months were included. The meta-analysis was based on the Mantel Haenszel method. Dental implant and prosthetic failure were the dichotomous outcome measures; these were evaluated through the risk ratio (RR) and odds ratio (OR), with corresponding 95% confidence intervals (CI). Of 499 articles identified, nine fulfilled the inclusion criteria. A total of 205 implants were placed in patients with a mean age of 64.1 years; the cumulative survival rate was 96.6% over a mean follow-up period of 37.3 months. The procedure used (SIMO vs. two implant-retained mandibular overdenture) did not affect dental implant failure (P=0.45) or prosthetic failure (P=0.65): RR 1.06 (95% CI 0.91-1.23) and RR 0.88 (95% CI 0.51-1.51), respectively; OR 2.56 (95% CI 0.27-24.39; P=0.41) and OR 0.44 (95% CI 0.15-1.26; P=0.13), respectively. Within the limitations of this systematic review and meta-analysis, SIMO with a complete denture as the opposing arch may be considered an alternative treatment for completely edentulous patients. However, this study also confirmed the need for more RCTs on this topic.

AB - A series of imidazo[2,1-b]thiazole-benzimidazole conjugates were synthesized and evaluated for their antiproliferative activity against four human cancer cell lines i.e.; HeLa (cervical), A549 (lung), MCF-7 (breast) and DU-145 (prostate) along with normal HEK-293 cell line. Amongst them, conjugate 6d displayed significant cytotoxicity against human lung cancer cell line, A549 with IC50 value 1.08 uM. Further, cell cycle analysis revealed that this compound arrested the cell cycle at G2/M phase in A549 cells. Furthermore, the tubulin polymerization assay results suggest that this conjugate (6d) exhibits significant inhibitory effect on the tubulin assembly with an IC50 value of 1.68 uM. Moreover, the apoptotic inducing properties of compound 6d was confirmed by Hoechst staining, measurement of mitochondrial membrane potential (DeltaPsim) and annexin V-FITC assay. Further, molecular docking studies revealed that compound 6d occupied the colchicine binding site.

AB - Four series of para or meta - substituted thiazolylbenzenesulfonamides bearing Cl substituents were designed, synthesized, and evaluated as inhibitors of all 12 catalytically active recombinant human carbonic anhydrase (CA) isoforms. Observed affinities were determined by the fluorescent thermal shift assay and the intrinsic affinities were calculated based on the fractions of binding-ready deprotonated sulfonamide and CA bearing protonated hydroxide bound to the catalytic Zn(II) in the active site. Several compounds exhibited selectivity towards CA IX, an anticancer target. Intrinsic affinities reached 30 pM, while the observed affinities - 70 nM. The structure-intrinsic affinity relationship map of the compounds showed the energetic contributions of the thiazole ring and its substituents. PMID- 29459131 TI - Perfluoroalkyl substances, glucose homeostasis, and gestational diabetes mellitus in Chinese pregnant women: A repeat measurement-based prospective study. AB - BACKGROUND: Exposure to perfluoroalkyl substances (PFASs) can affect glucose homeostasis and has been suggested as a potential risk of diabetes mellitus, but data are limited for pregnant women. OBJECTIVES: We aimed to explore the associations of exposure to PFASs with glucose homeostasis and gestational diabetes mellitus (GDM) in Chinese pregnant women. METHODS: The current study was conducted in Hebei Province of Northern China between 2013 and 2014 and 560 pregnant women were recruited in their early term of pregnancy and two representative serum PFASs, perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS), were measured. In 385 pregnant women who completed oral glucose tolerance test (OGTT), the associations of serum PFOA and PFOS concentrations with fasting blood glucose (FBG), fasting insulin (FIns), and homeostasis model assessment of insulin resistance (HOMA-IR) in the early, middle, and late terms of pregnancy and occurrence of GDM were examined using linear and Cox proportional hazard regression models. The reproducibility of serum PFASs during pregnancy was assessed in 230 pregnant women. RESULTS: The intraclass correlation coefficients of serum PFASs, covariates, and outcomes based on averaged repeat measurement (0.35-0.96) were higher than those based on single measurement (0.16 0.92). Serum PFOA was positively associated with averaged FIns and HOMA-IR in the early, middle, and late terms of pregnancy and averaged blood glucose level at 1 h and 2 h of OGTT, but serum PFOS tended to be negatively associated with averaged FBG and OGTT blood glucose. The adjusted hazard ratios of GDM associated with serum PFOA and PFOS were 1.98 (95% confidence interval: 0.70-5.57; p-value: 0.197) and 0.71 (0.29-1.75; 0.453), respectively. CONCLUSIONS: Our data raised a possibility that exposure to PFASs might have different influences on glucose homeostasis and GDM in Chinese pregnant women. More lab and human studies are needed to further test the hypothesis and investigate potential mechanisms.

PMID- 29459133 TI - Screening for Mullerian anomalies in patients with unilateral renal agenesis: Leveraging early detection to prevent complications. AB - BACKGROUND: Mullerian anomalies have a known association with renal agenesis yet, to date, there are no formal recommendations for screening women with certain renal anomalies for associated genital tract disorders. OBJECTIVE: The objective of this study is to review current data regarding the association between renal and Mullerian anomalies, and propose screening recommendations. STUDY DESIGN: A comprehensive review of the literature was performed to identify relevant articles using the keywords "unilateral renal agenesis," "renal anomalies," and "Mullerian anomalies." RESULTS: Over 30% of patients with unilateral renal agenesis have an associated Mullerian anomaly. However, diagnosis is frequently delayed in this population until after menarche when complications of retrograde menstruation with obstructive anomalies lead to significant problems including endometriosis, pelvic inflammatory disease, and infertility. No clear guidelines exist for communication among the antenatal sonographer, the obstetrician, the parents, and the child's pediatrician, which creates a barrier to effective screening and follow-up. Further, no current guidelines exist for screening women with certain renal anomalies for Mullerian anomalies. DISCUSSION: The complications of Mullerian anomalies are easily preventable if identified early. We propose new guidelines for education and screening for Mullerian anomalies in patients with unilateral renal agenesis (URA) and multicystic dysplastic kidney (MCDK) to guide providers, patients, and parents on proper identification and management (Table). CONCLUSIONS: Screening young women with URA and MCDK for Mullerian anomalies has the potential to prevent long-term complications from untreated obstructive malformations. Identification of unilateral renal agenesis on antenatal ultrasound must be clearly articulated with parents and the child's pediatrician so that proper screening can be performed before menarche. Pelvic sonography is a low-cost, high-yield screening tool to identify these anomalies. PMID- 29459134 TI - Upper pole access is safe and effective for pediatric percutaneous nephrolithotomy. AB - INTRODUCTION: Upper pole access in percutaneous nephrolithotomy (PCNL) provides a straight tract to the ureter, resulting in easier placement of a guidewire to the ureter, good exposure of the pelvis, calices, and upper ureter, and comfortable manipulations. However, despite these benefits, upper pole access is usually avoided because of the risk of chest complications in both pediatric and adult patients. OBJECTIVE: We aimed to evaluate the safety and morbidity of single upper pole access in pediatric patients undergoing PCNL. STUDY DESIGN: We retrospectively reviewed patients aged <=17 years with renal stones who underwent PCNL with a single access between August 2004 and February 2016. The patients were separated into two groups: the single upper pole access group (SUPAG) and the single other pole access group (SOPAG). We compared the SUPAG and SOPAG in terms of the demographic features of the patients, stone burden and location, operative data, and postoperative outcomes. Complications were classified according to the modified Clavien system. RESULTS: During the study period, 101 PCNL procedures were performed, 77 of which were managed with only one access. The median age of the 77 patients managed with a single access was 12 years (range 3-17 years). The number of cases in the SUPAG and SOPAG was 10 and 67, respectively. There were no statistically significant differences between the SUPAG and SOPAG in terms of age, sex, stone location, hydronephrosis status, stone area, side of kidney, and previous stone treatment or renal surgery. Furthermoret, there were no significant differences between the groups in terms of the operative parameters. Although the difference was insignificant, the median operation times in the SUPAG and SOPAG were 37 and 45 min, respectively. There was no chest complication or bleeding that required transfusion in the SUPAG. Two cases required transfusion, and one case was managed with a double pigtail catheter (double-J) placement because of prolonged extravasation in the SOPAG. The stone-free ratios were 100% and 82.1% in the SUPAG and SOPAG, respectively. CONCLUSION: Upper pole access provides similar outcomes to other (middle and lower) pole accesses, and may be performed without serious complications. These results indicate that this is a safe and effective approach of PCNL, and it presents a good alternative for removal of renal stones in pediatric patients.

AB - AIM: To evaluate microstructural visual pathway damage in patients with primary glaucoma (PG) by using 3 T diffusion kurtosis imaging (DKI). MATERIALS AND METHODS: The study was approved by the ethics committee, and all participants provided written informed consent. Ten patients with PG were examined. Twenty healthy individuals served as control subjects. DKI was performed with a GE Silent 3 T magnetic resonance imaging (MRI) unit. Mean diffusivity (MD), fractional anisotropy (FA), and mean kurtosis (MK) maps were automatically created. Mean MK, MD, and FA values were calculated for each part of the visual pathway. RESULTS: No abnormalities in the shape and signal intensity were observed along the entire visual pathway in patients and the control group on the conventional MRI. Higher MD, and lower MK and FA were observed in the optic nerves (ON), lateral geniculate nucleus (LGN), optic radiations (OR), and visual cortex (VCx) of PG patients, as compared with control subjects. A significantly higher MD was observed in the ON (p<0.01), and significantly lower FA was observed in OR (p<0.05). Additionally, significantly lower MK was observed in the ON, LGN, and VCx, except for OR (p<0.01). Changes of DKI parameters in the ON were the most distinct. CONCLUSION: Glaucoma is a complex neurological disease that affects the entire visual pathway. MK derived from DKI would be a better biomarkers than FA and MD in detecting microstructural damage. PMID- 29459138 TI - Could early tumour volume changes assessed on morphological MRI predict the response to chemoradiation therapy in locally-advanced rectal cancer? AB - AIM: To investigate the potential role of an additional magnetic resonance imaging (MRI) examination performed during neoadjuvant chemoradiation therapy (CRT) in the prediction of pathological response in locally advanced rectal cancer (LARC). MATERIAL AND METHODS: Forty-eight consecutive patients with LARC underwent neoadjuvant CRT. MRI studies at 1.5 T, including high-resolution T2 weighted sequences that were acquired parallel and perpendicular to the main axis of the tumour were performed before (preMRI), during (midMRI), and 6-8 weeks after the end of CRT (postMRI). Cancer volumes (Vpre, Vmid, Vpost) were drawn manually and the reduction rate calculated (DeltaVmid, DeltaVpost). According to Rodel's pathological tumour regression grade (TRG), patients were considered non responders (NR; TRG0-2), partial responders (PR; TRG3), and complete responders (CR; TRG4). Multivariate regression analysis was performed to identify the best MRI predictors of NR, PR, and CR. RESULTS: Twenty-five patients were considered PR (52%), 13 CR (27%), and 10 NR (22%). Tumour shrinkage mainly occurred shortly after CRT (DeltaVmid: CR: 80+/-10% versus PR: 56+/-19% versus NR: 28+/-22%, p=2.2*10-16). Vmid, Vpost, DeltaVmid, and DeltaVpost correlated with TRG (p<0.001). At multivariate analysis, the combined assessment of Vmid and DeltaVmid was selected as the best predictor of response to CRT, in that it distinguishes CR, PR, and NR early and accurately (81.5%). CONCLUSION: MidMRI allows final response assessment to neoadjuvant CRT earlier and better than the MRI performed after the end of CRT. MRI findings at midMRI may be useful to tailor patient treatment. PMID- 29459139 TI - Right adrenal vein: comparison between adaptive statistical iterative reconstruction and model-based iterative reconstruction. AB - AIM: To compare right adrenal vein (RAV) visualisation and contrast enhancement degree on adrenal venous phase images reconstructed using adaptive statistical iterative reconstruction (ASiR) and model-based iterative reconstruction (MBIR) techniques. MATERIAL AND METHODS: This prospective study was approved by the institutional review board, and written informed consent was waived. Fifty-seven consecutive patients who underwent adrenal venous phase imaging were enrolled. The same raw data were reconstructed using ASiR 40% and MBIR. The expert and beginner independently reviewed computed tomography (CT) images. RAV visualisation rates, background noise, and CT attenuation of the RAV, right adrenal gland, inferior vena cava (IVC), hepatic vein, and bilateral renal veins were compared between the two reconstruction techniques. RESULTS: RAV visualisation rates were higher with MBIR than with ASiR (95% versus 88%, p=0.13 in expert and 93% versus 75%, p=0.002 in beginner, respectively). RAV visualisation confidence ratings with MBIR were significantly greater than with ASiR (p<0.0001, both in the beginner and the expert). The mean background noise was significantly lower with MBIR than with ASiR (p<0.0001). Mean CT attenuation values of the RAV, right adrenal gland, IVC, and hepatic vein were comparable between the two techniques (p=0.12-0.91). Mean CT attenuation values of the bilateral renal veins were significantly higher with MBIR than with ASiR (p=0.0013 and 0.02). CONCLUSION: Reconstruction of adrenal venous phase images using MBIR significantly reduces background noise, leading to an improvement in the RAV visualisation compared with ASiR.

AB - CONTEXT: The first study of growth hormone receptor (GHR) genotypes in healthy young adults in the United States attending a Midwestern university and impact on selected growth parameters. OBJECTIVE: To describe the frequency of GHR genotypes in a sample of healthy young adults from the United States attending a university in the Midwest and analyze the relationship between GHR genotypes and selected growth parameters. DESIGN: Saliva was collected from 459 healthy young adults (237 females, 222 males; age range = 18-25 y) and DNA isolated for genotyping of GHR alleles (fl/fl, fl/d3, or d3/d3). Selected growth parameters were collected and GHR genotype data examined for previously reported associations (e.g., height, weight or bone mass density) or novel findings (e.g., % body water and index finger length). RESULTS: We found 219 participants (48%) homozygous for fl/fl, 203 (44%), heterozygous fl/d3 and 37 (8%) homozygous d3/d3. The distribution of GHR genotypes in our participants was consistent with previous reports of non-US populations. Several anthropometric measures differed by sex. The distribution of GHR genotypes did not significantly differ by sex, weight, or other anthropometric measures. However, the fl/d3 genotype was more common among African-Americans. CONCLUSIONS: Our study of growth and anthropometric parameters in relationship to GHR genotypes found no association with height, weight, right index finger length, BMI, bone mass density, % body fat or % body water in healthy young adults. We did identify sex differences with increased body fat, decreased bone density, body water and index finger length in females. PMID- 29459142 TI - Modulation of human corticospinal excitability by paired associative stimulation in patients with amyotrophic lateral sclerosis and effects of Riluzole. AB - BACKGROUND: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease that causes an impairment in both the upper and lower motor neurons. The recent description of numerous non-motor signs points to an involvement of the neocortex networks that is more complex than was previously believed. Paired associative stimulation (PAS), a combination of transcranial magnetic stimulation (TMS) and peripheral nerve stimulation, can enhance motor output in the contralateral hand through an NMDA-mediated sensorimotor mechanism. OBJECTIVE: To describe the effects of PAS on ALS patients before and after Riluzole intake compared with healthy subjects. METHODS: PAS was used to detect differences between 24 newly diagnosed ALS patients and 25 age-matched healthy controls. MEP amplitude from the abductor pollicis brevis was considered before PAS, immediately after (T0) and after 10 (T10), 20 (T20), 30 (T30) and 60 (T60) minutes. Statistical significance was calculated using RM-ANOVA. RESULTS: In healthy controls, PAS significantly increased MEP amplitude at T10, T20 and T30 (p < 0.05). In ALS patients, a significant increase in MEP amplitude was also observed after 60 min (p < 0.05), thus demonstrating NMDA-mediated enhanced facilitatory plasticity. After two weeks of riluzole intake, no MEP amplitude increase was evident after PAS at any time point. In three monomelic-onset ALS patients, a long lasting sensorimotor facilitation was evident only in the hemisphere corresponding to the affected side and appeared in the opposite hemisphere when the patients manifested contralateral symptoms. CONCLUSIONS: PAS may be considered a useful tool when investigating NMDA-mediated neocortical networks in ALS patients and the modulation of such networks after anti-glutamatergic drug intake. PMID- 29459143 TI - ESCMID Study Group for Infections in Compromised Hosts (ESGICH) Consensus Document on the safety of targeted and biological therapies: an infectious diseases perspective (Soluble immune effector molecules [I]: anti-tumor necrosis factor-alpha agents). AB - BACKGROUND: The present review is part of the ESCMID Study Group for Infections in Compromised Hosts (ESGICH) Consensus Document on the safety of targeted and biological therapies. AIMS: To review, from an Infectious Diseases perspective, the safety profile of agents targeting tumour necrosis factor-alpha (TNF-alpha) and to suggest preventive recommendations. SOURCES: Computer-based MEDLINE searches with MeSH terms pertaining to each agent or therapeutic family. CONTENT: Preclinical and clinical evidence indicate that anti-TNF-alpha therapy (infliximab, adalimumab, golimumab, certolizumab pegol and etanercept) is associated with a two-to four-fold increase in the risk of active tuberculosis and other granulomatous conditions (mostly resulting from the reactivation of a latent infection). In addition, it may lead to the occurrence of other serious infections (bacterial, fungal, opportunistic and certain viral infections). These associated risks seem to be lower for etanercept than other agents. Screening for latent tuberculosis infection should be performed before starting anti-TNF-alpha therapy, followed by anti-tuberculosis therapy if appropriate. Screening for chronic hepatitis B virus (HBV) infection is also recommended, and antiviral prophylaxis may be warranted for hepatitis B surface antigen-positive individuals. No benefit is expected from the use of antibacterial, anti Pneumocystis or antifungal prophylaxis. Pneumococcal and age-appropriate antiviral vaccinations (i.e. influenza) should be administered. Live-virus vaccines (i.e. varicella-zoster virus or measles-mumps-rubella) may be contraindicated in people receiving anti-TNF-alpha therapy, although additional data are needed before definitive recommendations can be made. IMPLICATIONS: Prevention measures should be implemented to reduce the risk of latent tuberculosis or HBV reactivation among individuals receiving anti-TNF-alpha therapy.

AB - A series of 4-aryl-thieno[1,4]diazepin-2-one were synthesized and evaluated for their antiproliferative activities against the A375P melanoma and U937 hematopoietic cell lines. Several compounds showed very potent antiproliferative activities toward both cell lines and the activities were better than that of sorafenib, the reference standard. Derivatives were made as amide (8a-8i, 9a-9m) and urea (10a-10d, 11a-11d) with diverse hydrophobic moieties. One of the most potent inhibitor 10d, 1-(4-((4-ethylpiperazin-1-yl)methyl)-3 (trifluoromethyl)phenyl)-3-(4-(2-oxo-2,3-dihydro-1H-thieno [3,4-b][1,4]diazepin-4 yl)phenyl)urea was found to be very potent inhibitor of multi-protein kinases including FMS kinase (IC50 = 3.73 nM) and is a promising candidate for further development in therapeutics for cancer.

AB - A new class of corticotropin releasing factor 1 (CRF1) receptor antagonists characterized by a tricyclic core ring was designed and synthesized. Novel tricyclic derivatives 2a-e were designed as CRF1 receptor antagonists based on conformation analysis of our original 2-anilinobenzimidazole CRF1 receptor antagonist. The synthesized tricyclic derivatives 2a-e showed CRF1 receptor binding activity with IC50 values of less than 400 nM, and the 1,2,3,4 tetrahydropyrimido-[1,2-a]benzimidazole derivative 2e was selected as a lead compound with potent in vitro CRF1 receptor binding activity (IC50 = 7.1 nM). To optimize the pharmacokinetic profiles of lead compound 2e, we explored suitable substituents on the 1-position and 6-position, leading to the identification of compound 42c-R, which exhibited potent CRF1 receptor binding activity (IC50 = 58 nM) with good oral bioavailability (F = 68% in rats). Compound 42c-R exhibited dose-dependent inhibition of [125I]-CRF binding in the frontal cortex (5 and 10 mg/kg, p.o.) as well as suppression of locomotor activation induced by intracerebroventricular administration of CRF in rats (10 mg/kg, p.o.). These results suggest that compound 42c-R successfully binds CRF1 receptors in the brain and exhibits the potential to be further examined for clinical studies.

AB - In this study, a series of 2-arylthio-5-iodo pyrimidine derivatives, as non nucleoside hepatitis B virus inhibitors, were evaluated and firstly reported as potential anti-HBV agents. To probe the mechanism of active agents, DHBV polymerase was isolated and a non-radioisotopic assay was established for measuring HBV polymerase. The biological results demonstrated that 2-arylthio-5 iodo pyrimidine derivatives targeted HBV polymerase. In addition, pharmacophore models were constructed for future optimization of lead compounds. Further study will be performed for the development of non-nucleoside anti-HBV agents. PMID- 29459147 TI - CycLS: Accurate, whole-library sequencing of cyclic peptides using tandem mass spectrometry. AB - Cyclic peptides are of great interest as therapeutic compounds due to their potential for specificity and intracellular activity, but specific compounds can be difficult to identify from large libraries without resorting to molecular encoding techniques. Large libraries of cyclic peptides are often DNA-encoded or linearized before sequencing, but both of those deconvolution strategies constrain the chemistry, assays, and quantification methods which can be used. We developed an automated sequencing program, CycLS, to identify cyclic peptides contained within large synthetic libraries. CycLS facilitates quick and easy identification of all library-members via tandem mass spectrometry data without requiring any specific chemical moieties or modifications within the library. Validation of CycLS against a library of 400 cyclic hexapeptide peptoid hybrids (peptomers) of unique mass yielded a result of 95% accuracy when compared against a simulated library size of 234,256 compounds. CycLS was also evaluated by resynthesizing pure compounds from a separate 1800-member library of cyclic hexapeptides and hexapeptomers with high mass redundancy. Of 22 peptides resynthesized, 17 recapitulated the retention times and fragmentation patterns assigned to them from the whole-library bulk assay results. Implementing a database-matching approach, CycLS is fast and provides a robust method for sequencing cyclic peptides that is particularly applicable to the deconvolution of synthetic libraries.

AB - INTRODUCTION: The aim of this study was to assess the role of root canal irrigants and medicaments in endodontic injuries verified in Finland and to estimate the rate of such events over time. METHODS: The study material comprised all endodontic injuries verified by the Patient Insurance Centre in 2002 to 2006 (n = 521) and 2011 to 2013 (n = 449). The data, based on patient documents scrutinized by 2 specialists in endodontics, included patients' and dentists' sex and age and the service sector. We recorded the use of root canal irrigants and medicaments, each as a dichotomy. Furthermore, we dichotomized the injuries as those related to root canal irrigants/medicaments and any other injuries. The injuries were also dichotomized as avoidable (could have been avoided by following good clinical practice) or unavoidable (normal treatment-related risks). Statistical evaluation used chi-square tests and t tests; logistic regression produced odds ratios (ORs). RESULTS: The verified injuries (N = 970) comprised 635 (65%) avoidable and 335 (35%) unavoidable injuries. The number of irrigant-/medicament-related injuries was 69, accounting for 7.1% of all verified injuries; all resulted from sodium hypochlorite and calcium hydroxide, and 87% were avoidable. The overall rate of sodium hypochlorite/calcium hydroxide injuries was 4.3 cases per 100,000 endodontic patients per year. Compared with other injuries, sodium hypochlorite/calcium hydroxide injuries were more likely avoidable (OR = 3.8) and more than 5-fold likely in 2011 to 2013 than in 2002 to 2006 (OR = 5.6). CONCLUSIONS: Extreme care is needed when applying sodium hypochlorite and calcium hydroxide into root canals to avoid increasing harmful consequences.

AB - INTRODUCTION: Prilocaine plain has a high pH and concentration (4%), which could decrease the pain of injection and increase success. The purpose of this study was to compare pain associated with anesthetic solution deposition and the degree of pulpal anesthesia obtained with the combination of prilocaine and lidocaine versus a lidocaine and lidocaine combination when used for inferior alveolar nerve blocks (IANBs). METHODS: One hundred eighteen asymptomatic subjects were randomly given a combination of 1 cartridge of 4% prilocaine plain plus 1 cartridge of 2% lidocaine with 1:100,000 epinephrine or a combination of 2 cartridges of 2% lidocaine with 1:100,000 epinephrine for the IANB at 2 separate appointments. Subjects rated the pain associated with anesthetic solution deposition of injection. Mandibular teeth were tested with an electric pulp tester every 4 minutes for 57 minutes. Anesthesia was considered successful when 2 consecutive 80 readings were obtained within 17 minutes and the 80 reading was continuously sustained for 57 minutes. Comparisons for anesthetic success were analyzed using the exact McNemar test, and pain ratings associated with anesthetic solution deposition were analyzed using multiple Wilcoxon matched pairs signed rank tests; both were adjusted using the step-down Bonferroni method of Holm. RESULTS: Four percent prilocaine plain was significantly less painful upon anesthetic solution deposition. Pulpal anesthetic success was not significantly different between the 2 combinations. CONCLUSIONS: The combination of 4% prilocaine plain plus 2% lidocaine with 1:100,000 epinephrine did not increase pulpal anesthetic success for IANBs compared with a combination of 2 cartridges of 2% lidocaine with 1:100,000 epinephrine. Pain associated with anesthetic solution deposition from the first cartridge of 4% prilocaine plain was significantly less when compared with the first cartridge of 2% lidocaine with 1:100,000 epinephrine.

AB - INTRODUCTION: Pericervical dentin (PCD) loss may increase root fracture propensity in root-filled teeth. This study evaluated the impacts of bonding PCD with composite resin (CR) on radicular microstrain distribution and load at failure of root-filled maxillary premolars. METHODS: Ten single-canal maxillary premolars decoronated 2 mm coronal to the cementoenamel junction (CEJ) had canals enlarged with ProTaper Universal instruments (Dentsply Tulsa Dental Specialties, Tulsa, OK) to F3. They were root filled with gutta-percha (GP) to the CEJ and restored with Cavit (3M Deutschland GmbH, Neuss, Germany) (GP group, n = 5) or 6 mm apical to the CEJ and restored with bonded CR to simulate bonding of PCD (bonded PCD group, n = 5). Digital moire interferometry was used to evaluate pre- and postoperative whole-field microstrain distribution in the root dentin under physiologically relevant loads (10-50 N). Another 30 premolars, similarly treated as groups 1 and 2 or left untreated as controls (n = 10/group), were subjected to cyclic loads (1.2 million cycles, 45 N, 4 Hz) followed by uniaxial compressive load to failure. Mechanical data were analyzed with 1-way analysis of variance and the post hoc Tukey test at a 5% level of significance. RESULTS: Microstrain distribution showed bending and compressive patterns at the coronal and apical root dentin, respectively. In the GP group, microstrain distribution was unaltered. In the bonded-PCD group, different microstrain distribution suggested stiffening at the PCD. The load at failure did not differ significantly for the GP, bonded PCD, and control groups (P > .05). CONCLUSIONS: CR bonding of PCD might impact the biomechanical responses in maxillary premolar roots at low-level continuous loads. The effect of this impact on root fracture loads when subjected to cyclic load warrants further investigation. PMID- 29459152 TI - Dose-response curves for MRI-detected radiation-induced temporal lobe reactions in patients after proton and carbon ion therapy: Does the same RBE-weighted dose lead to the same biological effect? AB - PURPOSE: To derive the dose-response curve for temporal lobe reactions (TLRs) after proton therapy and to compare the resulting relative biological effectiveness (RBE)-weighted tolerance doses based on an RBE of 1.1 with published values for carbon ions, which were calculated by the two versions of the local effect model (LEM I or IV). METHODS AND MATERIALS: 62 patients treated with protons for skull base tumors were analyzed for TLRs using magnetic resonance imaging. Within the mean follow-up time of 38 months, TLRs were observed in six patients. Dose-response curves based on the RBE-weighted maximum dose, excluding the 1 cm3-volume with the highest dose, were derived and compared to previously published dose-response curves for carbon ions, which were obtained using LEM I or IV, respectively. RESULTS: The dose-response curves for protons and LEM I were found to be almost identical while the curve of LEM IV was shifted toward higher doses. The resulting tolerance doses at the 5% effect level were 68.2+2.7-5.6, 68.6+3.0-3.9 and 78.3+3.8-5.0 Gy (RBE), respectively. CONCLUSIONS: The RBE-weighted dose prescription for protons leads to the same RBE-weighted dose-response curve for TLR as the one for LEM I-based carbon ions, while LEM IV predicts clinically significant higher tolerance doses. PMID- 29459153 TI - A statistical comparison of motion mitigation performances and robustness of various pencil beam scanned proton systems for liver tumour treatments. AB - BACKGROUND AND PURPOSE: Different scanned proton therapy systems provide different scanning scenarios, directly changing the temporal interference between sequential beam delivery and tumour motion. We aim here to quantify the interplay effects and compare motion mitigation performance among different PBS scanning systems. MATERIALS AND METHODS: Using 6 4DCT(MRI) datasets of liver tumours with irregular motions greater than 10 mm, 4D treatments with single- and double-field plans, and assuming various doses and motion mitigation approaches, were simulated for 8 PBS scenarios including spot or raster scanning, layered or volumetric rescanning, gating, constant or varying beam current and cyclotron or synchrotron beam sources. The resulting 4D plans were compared using the homogeneity index (D5-D95 in CTV) and treatment time. RESULTS: Independent of scanning scenario and field dose, neither gating nor rescanning alone could mitigate motion effects completely. Re-gating (rescanning with gating) however was found to be similarly effective for all scanning scenarios, most field doses and both rescan modes, with the difference being mainly in the treatment efficiency. The advantage of cyclotron-based systems together with layer-by-layer beam current variation was demonstrated by the nearly constant treatment time as a function of increased field dose. CONCLUSION: Independently of PBS scanning dynamics, re-gating is sufficient to achieve acceptable 4D plan quality close to those of the static references. PMID- 29459154 TI - Effect of different types of dental anchorage following first premolar extraction on mandibular third molar angulation. AB - OBJECTIVES: The aim of this study was to determine the effect of first premolar extraction with different anchorages as well as non-extraction on mandibular third molar angulation. MATERIALS AND METHODS: The pretreatment (T1) and posttreatment (T2) panoramic radiographs of one hundred patients from Hamadan (Iran), who underwent fixed orthodontic treatment were investigated and the angle between long axis of right mandibular third molars and a constructed horizontal plan (HRP) was measured. The sample was equally divided into four groups including first premolar extraction with maximum anchorage, that with moderate anchorage, that with minimum anchorage and non-extraction group. RESULTS: In the first premolar extraction groups with moderate and minimum anchorages, third molar angulation increased (8.12 and 7.48 degrees , respectively) significantly from T1 to T2 (P=0.001 and 0.003, respectively), but in the first premolar extraction group with maximum anchorage and non-extraction group, increase in third molar angulation (2.84 and 0.8 degrees , respectively) was not statistically significant (P=0.082 and 0.943, respectively). Third molar uprighting was significantly different among four groups using one-way ANOVA (P=0.004). Tukey (HSD: honestly significant difference) post hoc test indicated that difference in third molar angulation was statistically significant between first premolar extraction group with moderate anchorage and non-extraction group (P=0.007) and also between the first premolar extraction group with minimum anchorage and non-extraction group (P=0.024). CONCLUSION: The first premolar extraction groups with moderate and minimum anchorage may lead to more chance of third molar eruption and this can be helpful in borderline cases to consider third molar angulation as one of determining indicators to decide whether to extract or not to extract first premolars. PMID- 29459155 TI - Decreased bone density induced by antiepileptic drugs can cause accelerated orthodontic tooth movement in male Wistar rats. AB - PURPOSE: The aim of the present study was to evaluate the effect of the carbamazepine and valproic acid on orthodontic tooth movement in male Wistar rats. METHODS: Evaluation of tooth movement after 21 days of drugs infusion was carried out by feeler gauge. Bone densitometry on lateral cephalograms was conducted on days 1 and 21. After dissection of the maxillae, histologic parameters were evaluated. RESULTS: Orthodontic tooth movement was accelerated in experimental groups rather than controls. Optical density was significantly increased in these groups. In histologic sections, mesioapical portion of the PDL (Periodontal Ligament) was wider in experimental groups. Also, distoapical portion of the PDL was wider only in valproic acid group. CONCLUSION: Valproic acid and carbamazepine can decrease the bone density which may induce the accelerated orthodontic tooth movement in rats. PMID- 29459156 TI - ? PMID- 29459157 TI - ?

AB - Two-step preparation of iron and cobalt-containing MCM-56 zeolites has been undertaken to evaluate the influence of their physicochemical properties in the selective catalytic reduction (NH3-SCR or DeNOx) of NO using NH3 as a reductant. Zeolites were prepared by the selective leaching of the framework cations by concentrated HNO3 solution and NH4F/HF mixture and consecutively, introduction of Co and Fe heteroatoms, in quantities below 1wt%. Further calcination allowed to obtain highly dispersed active species. Their evaluation and speciation was realized by adsorption of pyridine and NO, followed by FTIR spectroscopy. Both Fe MCM-56 zeolites showed excellent activities (maximum NO conversion 92%) with high selectivity to dinitrogen (above 99%) in the high temperature NH3-SCR process. High catalytic activity of Fe-MCM-56 zeolites was assigned to the formation of stable nitrates, delivering NO to react with NH3 at higher temperatures and suppressing the direct NO oxidation. It was found that more nitrates was formed in Fe-MCM-56 (HNO3) than in Fe-MCM-56 (HF/NH4F) and that could compensate for the lower Fe loading, resulting in very similar catalytic activity of both catalysts. At the same time both Co-and Fe-MCM-56 zeolites were moderately active in direct N2O decomposition, with maximum N2O conversion not higher than 80% and activity window starting at 500 degrees C. This phenomenon was expected since both types of catalysts contained well dispersed active centers, not beneficial for this reaction. PMID- 29459159 TI - Structural sensitivity of CH vibrational band in methyl benzoate. AB - The CH vibrational bands of methyl benzoate are studied to understand its coupling pattern with other vibrational bands of the biological molecule. This will facilitate to understand the biological structure and dynamics in spectroscopic as well as in microscopic study. Due to the congested spectroscopic pattern, near degeneracy, and strong anharmonicity of the CH stretch vibrations, assignment of the CH vibrational frequencies are often misleading. Anharmonic vibrational frequency calculation with multidimensional potential energy surface interprets the CH vibrational spectra more accurately. In this article we have presented the importance of multidimensional potential energy surface in anharmonic vibrational frequency calculation and discuss the unexpected red shift of asymmetric CH stretch vibration of methyl group. The CD stretch vibrational band which is splitted to double peaks due to the Fermi resonance is also discussed here. PMID- 29459160 TI - Antimicrobial activity, cytotoxicity and DNA binding studies of carbon dots. AB - In recent years, quantum dots (QDs) are one of the most promising nanomaterials in life sciences community due to their unexploited potential in biomedical applications; particularly in bio-labeling and sensing. In the advanced nanomaterials, carbon dots (CDs) have shown promise in next generation bioimaging and drug delivery studies. Therefore the knowledge of the exact nature of interaction with biomolecules is of great interest to designing better biosensors. In this study, the interaction between CDs derived from tamarind and calf thymus DNA (ct-DNA) has been studied by vital spectroscopic techniques, which revealed that the CDs could interact with DNA via intercalation. The apparent association constant has been deduced from the absorption spectral changes of ct-DNA-CDs using the Benesi-Hildebrand equation. From the DNA induced emission quenching experiments the apparent DNA binding constant of the CDs (Kapp) have also been evaluated. Furthermore, we have analyzed the antibacterial and antifungal activity of CDs using disc diffusion assay method which exhibited excellent activity against E. coli and C. albicans with inhibition zone in the range of 7-12mm. The biocompatible nature of CDs was confirmed by an in vitro cytotoxicity test on L6 normal rat myoblast cells by using MTT assay. The cell viability is not affected till the high dosage of CDs (200MUg/mL) for >48h. As a consequence of the work, future development of CDs for microbial control and DNA sensing among the various biomolecules is possible in view of emerging biofields. PMID- 29459161 TI - Mercury concentration and the absolute and relative sizes of the internal organs in cormorants Phalacrocorax carbo (L. 1758) from the breeding colony by the Vistula Lagoon (Poland). AB - This work analyses the effect of mercury on the condition of cormorants (Phalacrocorax carbo) from an extensive breeding colony in northern Poland, the largest in Europe. A total of 55 birds (44 adults and 11 immature) were obtained. Total mercury (Hg) concentrations were measured in the liver, kidneys, breast muscles, heart, gullet (oesophagus), stomach, intestines, trachea, lungs and eyeballs. The total body mass (TBM) and empty body mass (EBM) were measured, and the body parts taken for analysis were weighed. The relative mass of the tissues and the L/K index were expressed as percentages. Based on the L/K index the birds were divided into three condition classes: (A) very good, (B) good and (C) moderate. The mean TBM and EBM in these cormorants were 2286 and 2184 g respectively. The greatest contributions to EBM were from the breast muscles (~11%), liver (3.7%) and intestines (3.0%). The stomach, gullet, lungs, heart and kidneys made up from ~1.0-2.8% EBM, and the trachea and eyeballs < 0.4%. 31 of the 55 birds analysed were allocated to class B; mean Hg levels in them were the highest in the kidneys, liver, lungs and muscles (18.3, 9.78, 2.70, 1.86 ug/g dw respectively); they were <= 1 ug/g in the other tissues. In ecotoxicology it is assumed that a hepatic concentration > 16.7 ug Hg/g dw can lead to adverse effects in the reproduction of non-marine birds. In the light of the present results, the reproductive parameters of the cormorants from the colony in northern Poland, though mostly in good or very good condition, may be depressed as a result of elevated Hg levels in their body tissues. PMID- 29459162 TI - Enrichment, spatial distribution of potential ecological and human health risk assessment via toxic metals in soil and surface water ingestion in the vicinity of Sewakht mines, district Chitral, Northern Pakistan. AB - This study focuses on enrichment, spatial distribution, potential ecological risk index (PERI) and human health risk of various toxic metals taken via soil and surface water in the vicinity of Sewakht mines, Pakistan. The samples of soils (n = 54) of different fields and surface water (n = 38) were analyzed for toxic metals including cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), iron (Fe), manganese (Mn), lead (Pb), nickel (Ni), zinc (Zn) and molybdenum (Mo). Soil pollution level was evaluated using pollution indices including geo-accumulation index (Igeo), contamination factor (CF), degree of contamination (CD), enrichment factor (EF) and PERI. CF showed moderate contamination of soil with Cd, Co, Fe and Mo, while Igeo values indicated moderate accumulation of Cu. For Cd, EF> 1.5 was found in agricultural soils of the study area. PERI findings presented a very high ecological risk (PERI > 380) at two sites (4%), considerable ecological risk at four sites (7.4%). Non-carcinogenic risk from exposure to Fe in soil was higher than limit (HI > 1) for both children and adults. Moreover, carcinogenic risk postured by soil contaminants i.e. Cd, Cr, Co and Ni in children was higher than their limits (except Pb), while in adults only Co posed higher risk of cancer than the limit (10-4) through soil exposure. Non-carcinogenic risks in children due to Cd, Co, Mo via surface water intake were higher than their safe limits (HQ > 1), while in adults the risk order was Cr > Cd > Cu > Pb > Co > Mo. Moreover, carcinogenic risk exposure due to Co > Cd > Cr > Ni from surface water (except Pb) was higher than the tolerable limit (1 * 10-4) both for children and adults. However, Pb concentrations in both soil and surface water exposure were not likely to cause cancer risk in the local population. PMID- 29459163 TI - Se enhanced phytoremediation of diesel in soil by Trifolium repens. AB - A pot-culture experiment was conducted to assess the effects of selenium (Se) (0.5 mg kg-1) on Trifolium repens exposed to various levels of diesel (0, 15, 20, 25 g kg-1) for 30 days and 60 days. Exposure to diesel for 60 day led to concentration-dependent decreases in root morphogenesis, chlorophyll content and CAT activity, and to dose-dependent increases in MDA content and SOD activity. The residual diesel concentration in soil increased and the removal efficiency decreased with soil diesel concentration. The chlorophyll content and residual diesel concentration after were slightly higher at 30 days than at 60days. Application of Se to soil increased Trifolium repens tolerance to diesel and significantly increased the phytoremediation effect at 60 days, with a removal rate of 36 +/- 8%, compared to 28 +/- 7% in the control. These results contribute to the ongoing effort to develop an effective phytoremediation system for soils highly contaminated by diesel. PMID- 29459164 TI - Synergistic effect of co-exposure to cadmium (II) and 4-n-nonylphenol on growth inhibition and oxidative stress of Chlorella sorokiniana. AB - Toxicological effect of freshwater algae co-exposure to Cd and 4-n-nonylphenol (4 n-NP) was seldom reported. In the present study, Chlorella sorokiniana was selected for testing the single and combined effect of Cd and 4-n-NP by detecting the growth inhibition and oxidative stress after exposure for 48 h, 72 h, and 96 h. The combined effects were evaluated by using toxic units (TU) method and concentration addition(CA)model. The synergistic effect of mixture on algal growth inhibition was both observed at 48 h and 72 h, and the additive effect was observed at 96 h. In addition, the significant alterations of superoxide, thiobarbituric acid reactive substances and antioxidant defenses (superoxide dismutase, catalase, glutathione) have been detected. It could be observed that the mixture predominantly lead to synergistic effects in superoxide induction, and the antagonistic effects in the GSH induction. A similar trend between the superoxide induction and growth inhibition were observed, which may indicate that the oxidative effects of Chlorella sorokiniana contributed to the growth inhibition after exposure to Cd and 4-n-NP. These findings may have important implications in the risk assessments of heavy metals and endocrine disruptors in the aquatic environment. PMID- 29459165 TI - House sparrow biomarkers as lead pollution bioindicators. Evaluation of dose and exposition length on hematological and oxidative stress parameters. AB - House sparrows (Passer domesticus) have been proposed as a key ecological indicator of urban pollution. Remarkably, we lack knowledge about the physiological effects of lead on this bird species. Therefore, this study was aimed to evaluate the effect of Pb on several physiological parameters in house sparrows exposed to environmental Pb concentrations. In a first experiment, birds were exposed to Pb sub-lethal doses (from 1.3 to 14.0 ug of Pb/g animal/day) during 5 days, which resulted in a dose response increase of blood Pb levels and decrease of blood ALAD activity. However, at the higher doses tested (> 7 MUg of Pb/g animal/day) the blood ALAD activity inhibition (~82%) remained constant. Hematocrit and hemoglobin were significantly reduced only at the highest-doses, and the stress indicator, heterophils to lymphocyte (H/L) ratio, did not show apparent changes. In a second experiment, house sparrows were exposed to Pb in drinking water (12.3 ppm) during either 15 or 30 days. Pb concentration used in this study was enough to produce blood lead levels equivalents to those found recently in house sparrows inhabiting urban areas, reduced blood ALAD activity and inversion of the H/L ratio. Decreasing blood ALAD activities were correlated with increasing blood Pb levels. In addition, Pb exposure produced modification in the levels of hepatic antioxidant enzymes, increased GST activity and decreased CAT activity, without lipid peroxidation. In conclusion, our results suggest that blood ALAD activity is a reliable and sensitive biomarker for environmental Pb exposure in house sparrows, additionally chronic exposure produce physiological stress (H/L inversion) and small changes in antioxidant enzyme activity. Finally, this specie could be considered a bioindicator for monitoring the urban Pb contamination. PMID- 29459166 TI - Acute blockade of inner ear marginal and dark cell K+ secretion: Effects on gravity receptor function. AB - Specific pharmacological blockade of KCNQ (Kv7) channels with XE991 rapidly (within 20 min) and profoundly alters inner ear gravity receptor responses to head motion (Lee et al., 2017). We hypothesized that these effects were attributable to the suppression of K+ secretion following blockade of KCNQ1-KCNE1 channels in vestibular dark cells and marginal cells. To test this hypothesis, K+ secretion was independently inhibited by blocking the Na+-K+-2Cl- cotransporter (NKCC1, Slc12a2) rather than KCNQ1-KCNE1 channels. Acute blockade of NKCC1 with ethacrynic acid (40 mg/kg) eliminated auditory responses (ABRs) within approximately 70 min of injection, but had no effect on vestibular gravity receptor function (VsEPs) over a period of 2 h in the same animals. These findings show that, vestibular gravity receptors are highly resistant to acute disruption of endolymph secretion unlike the auditory system. Based on this we argue that acute suppression of K+ secretion alone does not likely account for the rapid profound effects of XE991 on gravity receptors. Instead the effects of XE991 likely require additional action at KCNQ channels located within the sensory epithelium itself. PMID- 29459167 TI - Habitat characteristics provide insights of carbon storage in seagrass meadows. AB - Seagrass meadows provide multiple ecosystem services, yet they are among the most threatened ecosystems on earth. Because of their role as carbon sinks, protection and restoration of seagrass meadows contribute to climate change mitigation. Blue Carbon strategies aim to enhance CO2 sequestration and avoid greenhouse gasses emissions through the management of coastal vegetated ecosystems, including seagrass meadows. The implementation of Blue Carbon strategies requires a good understanding of the habitat characteristics that influence Corg sequestration. Here, we review the existing knowledge on Blue Carbon research in seagrass meadows to identify the key habitat characteristics that influence Corg sequestration in seagrass meadows, those factors that threaten this function and those with unclear effects. We demonstrate that not all seagrass habitats have the same potential, identify research priorities and describe the implications of the results found for the implementation and development of efficient Blue Carbon strategies based on seagrass meadows.

AB - CASE REPORT: Here we report a 19-year-old female patient who presented a vasoproliferative tumour. It caused complications, such as epiretinal membrane, macular oedema, vitreous haemorrhage, and exudative retinal detachment. The patient was treated with 3 injections of intravitreal bevacizumab, an intravitreal dexamethasone implant, tocilizumab, and double freeze-thaw cryotherapy. DISCUSSION: Therapeutic options are: observation, if it is small, if it is a peripheral lesion, and if there seems to be no threat to vision. If it requires treatment, laser photocoagulation, intravitreal bevacizumab, trans conjunctival cryotherapy, transpupillary thermotherapy, photodynamic therapy, brachytherapy plaques and surgery are the different options available. Recently, tocilizumab and intravitreal dexamethasone implants have been reported to be beneficial. PMID- 29459170 TI - Treatment of Cervical Spondylotic Amyotrophy With Nerve Transfers. AB - Cervical spondylotic amyotrophy is characterized by severe, proximal upper extremity weakness including an inability to abduct the shoulder and flex the elbow. Treatment using both medical and surgical decompression approaches has produced variable results. This paper reports the use of nerve transfers (spinal accessory to suprascapular, flexor carpi ulnaris fascicle of ulnar to biceps motor branch, radial nerve branch to triceps to axillary) to restore shoulder and elbow function in a case of unilateral cervical spondylotic amyotrophy involving C5 and C6 myotomes. Evidence of regeneration was observed on electromyography as well as clinically at 5 months postoperatively. At 3 years after surgery, recovery of elbow flexion and shoulder abduction was Medical Research Council grade 4/5 with improved external rotation and considerably improved patient-rated Disabilities of the Arm, Shoulder and Hand scores. We propose that nerve transfers be considered along with other reconstruction modalities in the treatment of cervical spondylotic amyotrophy. PMID- 29459171 TI - Tensile and Torsional Structural Properties of the Native Scapholunate Ligament. AB - PURPOSE: The ideal material for reconstruction of the scapholunate interosseous ligament (SLIL) should replicate the mechanical properties of the native SLIL to recreate normal kinematics and prevent posttraumatic arthritis. The purpose of our study was to evaluate the cyclic torsional and tensile properties of the native SLIL and load to failure tensile properties of the dorsal SLIL. METHODS: The SLIL bone complex was resected from 10 fresh-frozen cadavers. The scaphoid and lunate were secured in polymethylmethacrylate and mounted on a test machine that incorporated an x-y stage and universal joint, which permitted translations perpendicular to the rotation/pull axis as well as nonaxial angulations. After a 1 N preload, specimens underwent cyclic torsional testing (+/-0.45 N m flexion/extension at 0.5 Hz) and tensile testing (1-50 N at 1 Hz) for 500 cycles. Lastly, the dorsal 10 mm of the SLIL was isolated and displaced at 10 mm/min until failure. RESULTS: During intact SLIL cyclic torsional testing, the neutral zone was 29.7 degrees +/- 6.6 degrees and the range of rotation 46.6 degrees +/- 7.1 degrees . Stiffness in flexion and extension were 0.11 +/- 0.02 and 0.12 +/- 0.02 N m/deg, respectively. During cyclic tensile testing, the engagement length was 0.2 +/- 0.1 mm, the mean stiffness was 276 +/- 67 N/mm, and the range of displacement was 0.4 +/- 0.1 mm. The dorsal SLIL displayed a 0.3 +/- 0.2 mm engagement length, 240 +/- 65 N/mm stiffness, peak load of 270 +/- 91 N, and displacement at peak load of 1.8 +/- 0.3 mm. CONCLUSIONS: We report the torsional properties of the SLIL. Our novel test setup allows for free rotation and translation, which reduces out-of-plane force application. This may explain our observation of greater dorsal SLIL load to failure than previous reports. CLINICAL RELEVANCE: By matching the natural ligament with respect to its tensile and torsional properties, we believe that reconstructions will better restore the natural kinematics of the wrist and lead to improved outcomes. Future clinical studies should aim to investigate this further. PMID- 29459172 TI - Fracture Risk in Ulnohumeral Arthroplasty-A Biomechanical Study. AB - PURPOSE: Ulnohumeral arthroplasty, also known as the Outerbridge-Kashiwagi procedure, was popularized after reports of successful results in 1978, and has long been a means of management for ulnohumeral arthritis. However, there are concerns over the loss of integrity of the distal humerus as a result of fenestration. The purpose of this study was to examine the relationship between the size of fenestration and fracture risk. METHODS: Using a validated fourth generation sawbones model, load to failure and site of fracture were investigated following incrementally increasing distal humeral fenestration sizes. Each sample was subjected to a uniform extension stress on a materials testing system, with 5 samples run for each group. The experimental groups began with a fenestration size of 10 mm and increased by 3 mm increments up to 31 mm. Load at failure and site of fracture were recorded for each sample. RESULTS: Forty-five fourth generation sawbones samples were tested. Average load at sample failure was equivalent for each fenestration group up to 25 mm. At 28 mm, average load to failure began to decrease, and was statistically significant beginning between 28 mm and 31 mm. At 28 mm, 4 of 5 samples fractured through the fenestration, and at 31 mm, all 5 samples fractured through the fenestration. This change in fracture site became statistically significant between 25 mm and 28 mm. CONCLUSIONS: Distal humeral fenestration does compromise its structural integrity; however, for resection in the range of 10-25 mm, there is no increased risk of fracture. CLINICAL RELEVANCE: On the basis of this biomechanical model, the authors do not recommend any activity limitations after initial surgical recovery, but do recommend against distal humeral fenestrations larger than 25 mm when performing this procedure.

PMID- 29459174 TI - EFLDO induces apoptosis in hepatic cancer cells by caspase activation in vitro and suppresses tumor growth in vivo. AB - To study the apoptosis induced by EFLDO (ent-3alpha-formylabieta-8(14), 13(15) dien-16,12beta-olide), extracted from the Euphorbia lunulata Bge, in the HepG2 cell line and to study the antitumor activity of this compound in vivo, Cell viability and migration were evaluated with CCK-8 (2-(2-methoxy-4-nitrophenyl)-3- (4-nitrophenyl)-5-(2,4-disulfophenyl)-2H-tetrazolium, monosodium salt) and wound healing assays, respectively. In addition, the cell cycle was examined using flow cytometry after propidium iodide (PI) staining. Apoptosis was analyzed by using the Annexin V/PI staining assay. Pro-caspase activation and apoptosis protein expression were evaluated by western blotting. A HepG2 xenograft model in nude mice was also established to study the antitumor activity of EFLDO in vivo. Immunohistochemical analysis was used to detect the expression of Ki67 in the tumors in situ. EFLDO could induce dose- and time-dependent apoptosis in HepG2 human hepatic cancer cells. Activation of caspases 3, 8, and 9 played an important role in EFLDO-induced apoptosis in vitro. Decreased levels of Bcl-2 and Survivin and increased level of BAX were also involved in this process. Furthermore, EFLDO could inhibit HepG2 tumor growth in nude mice, and the proliferation characteristics, reflected by the Ki67 index, were suppressed significantly. The results indicated that EFLDO could induce apoptosis in hepatic cancer cells by caspase activation in vitro and suppress tumor growth in vivo. PMID- 29459175 TI - [Alveolar hemorrhage and cocaine use]. AB - In France, cocaine is the second most commonly illicit drug used after cannabis. Cocaine, mainly smoked in the form of crack, can be responsible for a wide range of respiratory disorders. The aim of this systematic literature review was to clarify what is known about the link between cocaine use and alveolar hemorrhage. We performed a Medline search covering the period 1980-2016 and collected data from 84 articles. The number of acute forms described in the literature is small but postmortem studies show that hidden forms are frequent. The diagnosis is based on the association of hemoptysis, anemia and diffuse alveolar opacity. Bronchoalveolar lavage shows hemosiderin-laden macrophages. Of the 13 cases identified, 12 patients had hemoptysis, anemia and diffuse alveolar infiltration on pulmonary or chest CT. In 9 cases, the presence of hemosiderin-laden macrophages was identified in bronchoalveolar lavage or pulmonary biopsy. Except for 2 deaths, the outcome was favorable when cocaine use was stopped. Systematic interventions to help people stopping using this psychoactive substance will protect lung health. PMID- 29459176 TI - Variations of T and B lymphocytes of flounder (Paralichthys olivaceus) after Hirame novirhabdovirus infection and immunization. AB - T and B lymphocytes are closely related to immunization and pathogen infection. Our previous study confirmed the CD3+, CD4-1+, CD4-2+, CD8beta+ T lymphocytes and IgM+ B lymphocytes presented in the peripheral blood leukocytes (PBLs) of flounder (Paralichthys olivaceus), in this paper, the variations of T and B lymphocytes of flounder after Hirame novirhabdovirus (HIRRV) infection or immunization were investigated. The flounders were injected with live or inactivated HIRRV, then the percentages of T and B lymphocytes in PBLs were analyzed by Flow cytometry (FCM), total antibodies and HIRRV-specific antibodies in serum were detected by Enzyme-linked immunosorbent assay (ELISA), and expression of twelve immune-related genes in the head kidneys were determined using q-PCR. The results showed that the percentages of CD3+, CD4-1+, CD4-2+, CD8beta+ T lymphocytes and IgM+ B lymphocytes significantly increased in both infection and immunization groups, in infection group they decreased rapidly after the peak and significantly lower than control levels at the end of infection, in immunization group they went down steadily to the control levels at the end of immunization. The total antibodies and HIRRV-specific antibodies increased first and peaked on the 7th day post infection and on the 14th day post immunization, respectively, then gradually decreased to the control levels. Additionally, twelve immune-related genes were up-regulated in both groups. These results demonstrated that the HIRRV induced both humoral and cellular immunity of flounder, the lymphocytes varied more sharply in infection group than those in immunization group and CD8+ T lymphocytes responded much more than CD4+ T lymphocytes to HIRRV antigen. PMID- 29459177 TI - IL-10 correlates with the expression of carboxypeptidase B2 and lymphovascular invasion in inflammatory breast cancer: The potential role of tumor infiltrated macrophages. AB - Pro-carboxypeptidase B2 (pro-CPB2) or thrombin-activatable fibrinolysis inhibitor (TAFI) is a glycoprotein encoded by the CPB2 gene and deregulated in several cancer types, including breast cancer. Thrombin binding to thrombomodulin (TM), encoded by THBD, is important for TAFI activation. CPB2 gene expression is influenced by genetic polymorphism and cytokines such as interleukin 10 (IL-10). Our previous results showed that tumor infiltrating monocytes/macrophages (CD14+/CD16+) isolated from inflammatory breast cancer (IBC) patients' secrete high levels of IL-10. The aim of the present study is to test genetic polymorphism and expression of CPB2 in healthy breast tissues and carcinoma tissues of non-IBC and IBC patients. Furthermore, to investigate whether IL-10 modulates the expression of CPB2 and THBD in vivo and in-vitro. We tested CPB2 Thr325Ile polymorphism using restriction fragment length polymorphism, (RFLP) technique in healthy and carcinoma breast tissues. The mRNA expression of CPB2, THBD and IL10 were assessed by RT-qPCR. Infiltration of CD14+ cells was assessed by immunohistochemistry. In addition, we investigated the correlation between infiltration of CD14+ cells and expression of IL10 and CPB2. Furthermore, we correlated IL10 expression with the expression of both CPB2 and THBD in breast carcinoma tissues. Finally, we validated the role of recombinant IL-10 in regulating the expression of CPB2 and THBD using different breast cancer cell lines. Our results showed that CPB2 genotypes carrying the high-risk allele [Thr/Ile (CT) and Ile/Ile (TT)] were more frequent in both IBC and non-IBC patients compared to control group. CPB2 genotypes did not show any statistical correlation with CPB2 mRNA expression levels or patients' clinical pathological properties. Interestingly, CPB2 and IL10 expression were significantly higher and positively correlated with the incidence of CD14+ cells in carcinoma tissues of IBC as compared to non-IBC. On the other hand, THBD expression was significantly lower in IBC carcinoma versus non-IBC tissues. Based on molecular subtypes, CPB2 and IL10 expression were significantly higher in triple negative (TN) as compared to hormonal positive (HP) carcinoma tissues of IBC. Moreover, CPB2 expression was positively correlated with presence of lymphovascular invasion and the expression of IL10 in carcinoma tissues of IBC patients. Furthermore, recombinant human IL 10 stimulated CPB2 expression in SUM-149 (IBC cell line) but not in MDA-MB-231 (non-IBC cell line), while there was no significant effect THBD expression. In conclusion, carcinoma tissues of IBC patients are characterized by higher expression of CPB2 and lower expression of THBD. Moreover, CPB2 positively correlates with IL10 mRNA expression, incidence of CD14+ cells and lymphovascular invasion in IBC patients. IL-10 stimulated CPB2 expression in TN-IBC cell line suggests a relevant role of CPB2 in the aggressive phenotype of IBC. PMID- 29459178 TI - The challenge of treating older patients with pancreaticobiliary malignancies. AB - Pancreatic and biliary tract cancers are aggressive malignancies. They commonly present with metastatic or unresectable disease. Those that do present with resectable cancer have high rates of recurrence. Despite recent advances in surgical technique, chemotherapy, and radiotherapy regimens, they are associated with poor survival outcomes. These cancers represent an exception to the trend of improved overall survival evident in most malignancies in recent decades. Depending on the goal of treatment, active management of pancreatic and biliary cancers involves surgery, chemotherapy, and radiation therapy, either alone or in combination. Both pancreatic and biliary tract cancers have a preponderance in the older population. Older patients are a heterogeneous group; although tolerability of multimodality treatment may be a challenge for some, many fit older patients may be undertreated based on their age alone. The growing field of geriatric oncology has highlighted the importance of a comprehensive assessment of these patients, and not relying on age alone as a discriminating factor for treatment. Management of older patients with pancreaticobiliary cancers is particularly challenging owing to limited prospective data in this population. As such, there is uncertainty with regard to optimal treatment approaches for these patients. In this article, we outline the therapeutic options available to patients with localized or advanced pancreatic and biliary tract cancers, and the evidence for specified treatment options in the elderly. We examine the inclusion and outcomes of elderly patients in relevant clinical trials; the morbidity that may be encountered by elderly patients receiving specified treatments and the tools that may assist the physician in selecting elderly patients for particular treatments. PMID- 29459179 TI - NMR analysis of substrate binding to a two-domain chitinase: Comparison between soluble and insoluble chitins. AB - CJP-4 is a two-domain chitinase from Japanese cedar (Cryptomeria japonica) pollen, consisting of an N-terminal CBM18 domain and a GH19 catalytic domain. The substrate binding to an inactive mutant protein of full-length CJP-4, in which the catalytic acid Glu108 was mutated to glutamine, CJP-4(E108Q), was analyzed by NMR spectroscopy. Based on the chemical shift perturbations of 1H-15N HSQC signals of Gly26 (CBM18 domain) and Trp185 (GH19 domain), the association constants for individual domains of CJP-4(E108Q) toward soluble chitin hexamer (GlcNAc)6 were determined to be 2300 and 3500 M-1, respectively. Isothermal titration calorimetry provided a similar association constant for (GlcNAc)6 (1980 M-1) with the one-site binding model. One (GlcNAc)6 molecule appeared to bind to a single binding site of CJP-4(E108Q), spanning from CBM18 to GH19 domains. When chitin nanofibers, insoluble chitinase substrate, were added to the CJP-4(E108Q) solution, strong line-broadening was observed for the majority of the backbone resonances in CBM18 domain but not in GH19 domain, indicating a binding preference of CBM18 domain to the insoluble chitin. We here demonstrated importance of CBM18 domain in insoluble chitin recognition based on the NMR binding data obtained for full-length CJP-4. Chitin nanofibers were found to be useful for spectroscopic observation of insoluble chitin binding to proteins. PMID- 29459180 TI - A new look at acid catalyzed deacetylation of carbohydrates: A regioselective synthesis and reactivity of 2-O-acetyl aryl glycopyranosides. AB - In the present work we report that acetyl groups of per - acetylated aryl glycosides have different reactivity during the acidic deacetylation using HCl/EtOH in CHCl3, which leads to preferential deacetylation at O-3, O-4 and O-6. Thereby, the one-step preparation of 2-O-acetyl aryl glycosides with simple aglycon was accomplished for the first time. It was proved that the found reagent is to be general and unique for the preparation of series of 2-O-acetyl aryl glycosides. We have determined the influence of both carbohydrate moiety and the aglycon on the selectivity of deacetylation reaction by kinetic experiments. Using DFT/B3LYP/6-31G(d,p) and semi-empirical AM1 methods we have found that the highest activation barrier is for 2-O-acetyl group. This completely explains the least reactivity of 2-O-acetyl group. PMID- 29459181 TI - Nuclear envelope rupture: little holes, big openings. AB - The nuclear envelope (NE), which is a critical barrier between the DNA and the cytosol, is capable of extensive dynamic membrane remodeling events in interphase. One of these events, interphase NE rupture and repair, can occur in both normal and disease states and results in the loss of nucleus compartmentalization. NE rupture is not lethal, but new research indicates that it could have broad impacts on genome stability and activate innate immune responses. These observations suggest a new model for how changes in NE structure could be pathogenic in cancer, laminopathies, and autoinflammatory syndromes, and redefine the functions of nucleus compartmentalization. PMID- 29459182 TI - Understanding epidemiologists who serve as preceptors. AB - PURPOSE: This study describes factors associated with epidemiologists from state health departments (HDs) who served as preceptors. METHODS: We used the 2014 Public Health Workforce Interests and Needs Survey, a national survey of state health agency workers, and selected those who identify their role in the organization as an epidemiologist and a state HD employee for analysis. Variables related to recruitment and retention were studied, and predictor variables were assessed. We applied statistical analysis of complex sampling design based on weights generated by the distribution of the epidemiologists. Logistic regression was used to determine factors that are significant predictors of preceptorship. RESULTS: Significant factors of increased preceptorship included being black (adjusted odds ratios [AOR] = 3.98, 95% confidence interval [CI], 2.01-7.88), being a team leader (AOR = 2.09, 95% CI, 1.07-4.05), a supervisor (AOR = 2.75, 95% CI, 1.25-6.08), or a manager (AOR = 2.70, 95% CI, 1.15-6.34), and collaborating with academia (AOR = 3.11, 95% CI, 1.82-5.34). CONCLUSIONS: State HDs and academic institutions should collaborate to offer applied epidemiology practicum opportunities to (1) increase job satisfaction among applied epidemiologists and (2) prepare the incoming workforce to work in applied epidemiology. PMID- 29459184 TI - Cadmium exposure and cognitive abilities and behavior at 10 years of age: A prospective cohort study. AB - BACKGROUND: We have previously reported inverse associations of prenatal and childhood cadmium exposure with cognition in 5-year-old Bangladeshi children. OBJECTIVES: To assess if cadmium exposure affected cognition and behavior in the Bangladeshi children at 10 years. METHODS: Cadmium exposure was assessed by urinary concentrations at 10 (n = 1498) and 5 years of age (n = 1453), and of the mothers in early pregnancy (n = 1299), measured by ICP-MS. Cognitive abilities were assessed with Wechsler Intelligence Scale for Children (4th edition) and behavior with the parent-rated Strengths and Difficulties Questionnaire. RESULTS: In multivariable-adjusted models, urinary cadmium at 10 years was inversely associated with Full scale IQ and most of the sub-scales. Associations were mainly observed in boys, in whom the difference in Full scale IQ was 7.0 scores (95% CI: -11, -2.7), corresponding to 0.21 SD, when comparing those in the highest (range: 0.30-2.6 MUg/L) and lowest tertile of urinary cadmium (0.036-0.18 MUg/L). Urinary cadmium at 5 years was inversely, but not significantly, associated with IQ. Children in the highest exposure tertile at 10 years also had poorer Prosocial behavior scores. The association appeared strongest in girls, in whom the corresponding OR for Prosocial scores in relation to cadmium exposure at 10 years and prenatally was 0.58 (95% CI: 0.34, 0.99) and 0.48 (95% CI: 0.25, 0.93), respectively. CONCLUSION: Childhood cadmium exposure was associated with lower intelligence in boys, and there were indications of altered behavior in girls for both prenatal and childhood exposures. Findings are of concern as similar exposure levels are common world-wide. PMID- 29459183 TI - Transcriptional differences between smokers and non-smokers and variance by obesity as a risk factor for human sensitivity to environmental exposures. AB - BACKGROUND: Obesity has been shown to alter response to air pollution and smoking but underlying biological mechanisms are largely unknown and few studies have explored mechanisms by which obesity increases human sensitivity to environmental exposures. OBJECTIVE: Overall study goals were to investigate whole blood gene expression in smokers and non-smokers to examine associations between cigarette smoke and changes in gene expression by obesity status and test for effect modification. METHODS: Relative fold-change in mRNA expression levels of 84 genes were analyzed using a Toxicity and Stress PCR array among 50 21-54 year old adults. Data on smoking status was confirmed using urinary cotinine levels. Adjusted models included age, gender, white blood cell count and body-mass index. RESULTS: Models comparing gene expression of smokers vs. non-smokers identified six differentially expressed genes associated with smoking after adjustments for covariates. Obesity was associated with 29 genes differentially expressed compared to non-obese. We also identified 9 genes with significant smoking/obesity interactions influencing mRNA levels in adjusted models comparing expression between smokers vs non-smokers for four DNA damage related genes (GADD45A, DDB2, RAD51 and P53), two oxidative stress genes (FTH1, TXN), two hypoxia response genes (BN1P3lL, ARNT), and one gene associated with unfolded protein response (ATF6B). CONCLUSIONS: Findings suggest that obesity alters human sensitivity to smoke exposures through several biological pathways by modifying gene expression. Additional studies are needed to fully understand the clinical impact of these effects, but risk assessments should consider underlying phenotypes, such as obesity, that may modulate sensitivity of vulnerable populations to environmental exposures. PMID- 29459185 TI - FAMI Screws for Mandibulo-Maxillary fixation in mandibular fracture treatment - Clinico-radiological evaluation. AB - Mandibulo-maxillary fixation (MMF) is indispensable for mandibular fracture treatment. Various means for MMF have been proposed, of which arch bars are widely considered to be the mainstay. However, disadvantages to this method have initiated a quest for an alternative, leading to the introduction of MMF screws. MMF screws have frequently been criticized for poor stability of fracture sites, root damage, hardware failure, and nerve damage. We retrospectively evaluate the FAMI (Fixation and Adaptation in Mandibular Injuries) screw in mandibular fracture treatment by scanning for clinically and radiologically visible complications. In total, 534 FAMI screws were used in the successful treatment of 96 males and 34 females. Condylar fractures were most commonly encountered, representing 120 of 241 fracture sites. 15 general fracture-related complications occurred, with the most common being nerve function impairment (3.8%) and postoperative malocclusion (4.6%). In nine cases (7%), clinically visible FAMI screw-related complications occurred, with the most prevalent being screw loosening (2.3%) and mucosal signs of inflammation (3.1%). Duration of FAMI screws was associated with the occurrence of clinically visible complications (p = 0.042). Radiologically, clinically invisible dental hard tissue damage was noted in 21 individuals (16%). Therefore, FAMI screws seem to be a reliable and safe method for mandibulo-maxillary fixation. PMID- 29459186 TI - Squamous cell carcinoma of the maxilla: Analysis of clinicopathological predictors for disease recurrence and metastatic behavior. AB - INTRODUCTION: Squamous cell carcinoma of the maxilla only constitutes a small fraction of Head and Neck Cancers. There is thereby a lack of information about frequent tumor staging and localization and their effect on patients' outcome. The main factors that influence longterm survival in HNSCC are the extent of the primary disease and recurrence rate, including local neck metastases. PATIENTS AND METHODS: In this study, clinical outcome and rates of disease recurrence in 68 surgically treated patients with maxillary SCC were evaluated in terms of primary tumor staging and localization. RESULTS: It could be demonstrated that maxillary cancer is mostly located in the posterior region of the upper jaw (70%). The rate of neck node metastasis was 35.3%, which is equivalent to the rest of the oral cavity and supports the role of elective neck dissection for patients with clinically negative neck node status. Staging, tumor differentiation, and infiltration of lymphatic structures correlated significantly with the development of local neck node metastases (r = 0.321, p = 0.01; r = 0.348, p < 0.01; r = 0.64; p < 0.01). CONCLUSION: Maxillary carcinomas exhibit similar rates of locoregional disease recurrence as the rest of the oral cavity. The existence of cervical metastases even in patients with T1 tumors supports the concept of elective neck dissection in early tumors with clinically negative neck status. PMID- 29459187 TI - Association between third molar and mandibular angle fracture: A systematic review and meta-analysis. AB - PURPOSE: The aim of this study was to investigate the risk of mandibular angle fracture associated with the presence of a mandibular third molar and its position when the mandibular fracture occurs. METHODS: A systematic literary search was performed in Pubmed, Scopus, and the Cochrane Library for observational studies with at least 250 patients that included frequency of mandibular angle fracture, presence of third molar, and its position. RESULTS: A total of seven studies were included in the review, from an initial search of 622 titles. The relative risk of mandibular angle fracture with third molar was 1.90 (95% CI = 1.47-2.46). The relative risk of mandibular angle fracture related to third molar position (according to the Pell and Gregory classification) was 1.18 (95% CI = 0.62-2.25), 1.98 (95% CI = 0.95-4.10), 2.72 (95% CI = 1.78-4.16), 1.31 (95% CI = 0.80-2.14), 2.21 (95% CI = 1.69-2.87) and 2.99 (95% CI = 2.12-4.22) for Class A, Class B, Class C, Class I, Class II, and Class III, respectively. CONCLUSIONS: Our meta-analysis reported a two-fold increased risk of mandibular angle fracture with the presence of a third molar in patients who presented with mandibular fractures. Even the third molar position seemed to influence mandibular angle fracture, especially Class C, Class II, and Class III. PMID- 29459189 TI - Detailed investigations into the Akabori-Momotani reaction for the synthesis of amphetamine type stimulants: Part 2. AB - The Akabori-Momotani reaction can be used to synthesise pseudoephedrine in 50% yield from N-methylalanine and benzaldehyde. This paper investigates electronic effects of substituted benzaldehydes on the reaction to synthesise amphetamine type stimulants and identifies several new Akabori-Momotani by-products, 1-[(4 methoxybenzyl)(methyl)amino]ethanol (11c), 2-(4-methoxyphenyl)-3,4-dimethyl-1,3 oxazolidine (12c), 1,2,3,4-tetramethyl-5,6-di-(4-methoxyphenyl)piperazine (13c) and 1,2,4,5-tetramethyl-3,6-di-(4-methoxyphenyl)piperazine (14c). This paper also investigates pseudoephedrine and methamphetamine isomeric distribution from the Akabori-Momotani reaction with the aid of molecular modelling to understand why more pseudoephedrine than ephedrine is produced. PMID- 29459188 TI - Acupuncture for the treatment of post-partum urinary retention. AB - STUDY OBJECTIVES: The aims of the present study were to evaluate acupuncture as an alternative treatment to an indwelling catheter for women with postpartum urinary retention, and to evaluate the accuracy of sonographic estimation of bladder volume by portable bedside equipment in women postpartum. STUDY BACKGROUND: Post-partum urinary retention is a common obstetric complication. The accepted method for diagnosing post void residual bladder volume is by ultrasound or catheterization. However, the accuracy of bedside sonographic evaluation of bladder volume in women postpartum is controversial due to anatomical and technical issues. The traditional treatment of urinary retention is catheterization for variable lengths of time. Acupuncture, while an accepted treatment method for urinary retention in traditional societies in the Far East, has not been proven scientifically to resolve the problem. Therefore, the aims of our study were to evaluate acupuncture as an alternative treatment to catheterization for urinary retention, and to evaluate the accuracy of sonographic estimation of bladder volume by portable bedside ultrasound in women postpartum. MATERIALS AND METHODS: The study was a prospective randomized case controlled trial conducted in 55 women post-partum with urinary retention. All patients underwent a pre and post treatment sonographic evaluation of bladder volume. Women with urinary retention were given the choice of treatment by acupuncture or catheterization. Acupuncture was performed by an experienced acupuncturist licensed in Traditional Chinese Medicine and point selection was based on Meridian theory and clinical experience. RESULTS: In the acupuncture group, 23 women (92%) achieved spontaneous micturition within one hour following treatment. Bedside sonographic evaluation of bladder volume showed excellent correlation to actual volume as measured by catheterization (r2 = 0.988). CONCLUSION: Acupuncture proved to be an excellent alternative to catheterization in treatment of women with postpartum urinary retention. PMID- 29459190 TI - The Koukopoulos Mixed Depression Rating Scale (KMDRS): An International Mood Network (IMN) validation study of a new mixed mood rating scale. AB - BACKGROUND: It has been proposed that the broad major depressive disorder (MDD) construct is heterogenous. Koukopoulos has provided diagnostic criteria for an important subtype within that construct, "mixed depression" (MxD), which encompasses clinical pictures characterized by marked psychomotor or inner excitation and rage/anger, along with severe depression. This study provides psychometric validation for the first rating scale specifically designed to assess MxD symptoms cross-sectionally, the Koukopoulos Mixed Depression Rating Scale (KMDRS). METHODS: 350 patients from the international mood network (IMN) completed three rating scales: the KMDRS, Montgomery-Asberg Depression Rating Scale (MADRS) and Young Mania Rating Scale (YMRS). KMDRS' psychometric properties assessed included Cronbach's alpha, inter-rater reliability, factor analysis, predictive validity, and Receiver Operator Curve analysis. RESULTS: Internal consistency (Cronbach's alpha = 0.76; 95% CI 0.57, 0.94) and interrater reliability (kappa = 0.73) were adequate. Confirmatory factor analysis identified 2 components: anger and psychomotor excitation (80% of total variance). Good predictive validity was seen (C-statistic = 0.82 95% CI 0.68, 0.93). Severity cut off scores identified were as follows: none (0-4), possible (5-9), mild (10-15), moderate (16-20) and severe (> 21) MxD. LIMITATIONS: Non DSM-based diagnosis of MxD may pose some difficulties in the initial use and interpretation of the scoring of the scale. Moreover, the cross-sectional nature of the evaluation does not verify the long-term stability of the scale. CONCLUSIONS: KMDRS was a reliable and valid instrument to assess MxD symptoms. PMID- 29459191 TI - A review of the curriculum development process of simulation-based educational intervention studies in Korea. AB - BACKGROUND: Despite the increase in simulators at nursing schools and the high expectations regarding simulation for nursing education, the unique features of integrating simulation-based education into the curriculum are unclear. OBJECTIVE: The purpose of this study was to assess the curriculum development process of simulation-based educational interventions in nursing in Korea. DESIGN: Integrative review of literature used. DATA SOURCES: Korean Studies Information Services System (KISS), Korean Medical Database (KMbase), KoreaMed, Research Information Sharing Service (RISS), and National Digital Library (NDL). METHODS: Comprehensive databases were searched for records without a time limit (until December 2016), using terms such as "nursing," "simulation," and "education." A total of 1006 studies were screened. According to the model for simulation-based curriculum development (Khamis et al., 2016), the quality of reporting on the curriculum development was reviewed. RESULTS: A total of 125 papers were included in this review. In three studies, simulation scenarios were made from easy to difficulty levels, and none of the studies presented the level of learners' proficiency. Only 17.6% of the studies reported faculty development or preparation. The inter-rater reliability was presented in performance test by 24 studies and two studies evaluated the long-term effects of simulation education although there was no statistically significant change in terms of publication years. CONCLUSION: These findings suggest that educators and researchers should pay more attention to the educational strategies to integrate simulation into nursing education. It could contribute to guiding educators and researchers to develop a simulation-based curriculum and improve the quality of nursing education research. PMID- 29459192 TI - Investigating the impact of moulage on simulation engagement - A systematic review. AB - BACKGROUND: Simulation Based Education (SBE) is used as a primer for clinical education in nursing and other health professions. Participant engagement strategies and good debriefing have been identified as key for effective simulations. The environment in which the simulation is situated also plays a large role in the degree of participant engagement. Various cues are staged within simulations to enhance this engagement process. Moulage techniques are used in current-day simulation to mimic illnesses and wounds, acting as visual and tactile cues for the learner. To effectively utilise moulage in simulation, significant expense is required to train simulation staff and to purchase relevant equipment. OBJECTIVE: Explore the use of moulage in simulation practice today and its influence on participant engagement. DESIGN: Using a systematic process to extract papers, we reviewed the literature with a critical-realist lens. DATA SOURCES: CINAHL Complete, ERIC, Embase, Medline, PsycINFO, SCOPUS, Web of Science, Proquest, Science Direct and SAGE. REVIEW METHODS: 10 databases were systematically reviewed using the keyword "moulage" to answer the question "How does the authenticity of moulage impact on participant engagement?". 1318 records were identified prior to exclusion criterion were applied. 10 articles were targeted for review, following exclusion for English language and publication between 2005 and 2015. RESULTS: The resulting 10 papers were assessed for quality using the Medical Education Research Study Quality Instrument (MERSQI). The majority of papers were situated in dermatology teaching, with only one nursing paper. Study participants were both undergraduate and postgraduate. Most of the studies were undertaken at a university setting. No papers comprehensively addressed whether the authenticity of moulage influences learner engagement. CONCLUSIONS: Results were limited, yet clearly outline a widely held assumption that moulage is essential in simulation-based education for improved realism and subsequent learner engagement. Despite this, there is no clear evidence from the literature that this is the case, suggesting that further research to explore the impact of moulage on participant engagement is warranted. A number of recommendations are made for future research. PMID- 29459193 TI - Personal domains assessed in multiple mini interviews (MMIs) for healthcare student selection: A narrative synthesis systematic review. AB - OBJECTIVES: To examine the personal domains multiple mini interviews (MMIs) are being designed to assess, explore how they were determined and contextualise such domains in current and future healthcare student selection processes DESIGN: A systematic review of empirical research reporting on MMI model design was conducted from database inception to November 2017. DATA SOURCES: Twelve electronic bibliographic databases. REVIEW METHODS: Evidence was extracted from original studies, and integrated in a narrative synthesis guided by the PRISMA statement for reporting systematic reviews. Personal domains were clustered into themes using a modified Delphi technique. RESULTS: A total of 584 articles were screened. 65 unique studies (80 articles) matched our inclusion criteria of which seven were conducted within nursing/midwifery faculties. Six in 10 studies featured applicants to medical school. Across selection processes, we identified 32 personal domains assessed by MMIs, the most frequent being: communication skills (84%), teamwork/collaboration (70%), and ethical/moral judgement (65%). Domains capturing ability to cope with stressful situations (14%), make decisions (14%), and resolve conflict in the workplace (13%) featured in fewer than ten studies overall. Intra- and inter-disciplinary inconsistencies in domain profiles were noted, as well as differences by entry level. MMIs deployed in nursing and midwifery assessed compassion and decision-making more frequently than in all other disciplines. Own programme philosophy and professional body guidance were most frequently cited (~50%) as sources for personal domains; a blueprinting process was reported in only 8% of studies. CONCLUSIONS: Nursing, midwifery and allied healthcare professionals should develop their theoretical frameworks for MMIs to ensure they are evidence-based and fit-for-purpose. We suggest a re evaluation of domain priorities to ensure that students who are selected, not only have the capacity to offer the highest standards of care provision, but are able to maintain these standards when facing clinical practice and organisational pressures. PMID- 29459194 TI - The value of psychosocial group activity in nursing education: A qualitative analysis. AB - BACKGROUND: Nursing faculty often struggle to find effective teaching strategies for nursing students that integrate group work into nursing students' learning activities. OBJECTIVES: This study was conducted to evaluate students' experiences in a psychiatric and mental health nursing course using psychosocial group activities to develop therapeutic communication and interpersonal relationship skills, as well as to introduce psychosocial nursing interventions. METHODS: A qualitative research design was used. The study explored nursing students' experiences of the course in accordance with the inductive, interpretative, and constructive approaches via focus group interviews. Participants were 17 undergraduate nursing students who registered for a psychiatric and mental health nursing course. The collected data were analyzed by qualitative content analysis. RESULTS: The analysis resulted in 28 codes, 14 interpretive codes, 4 themes (developing interpersonal relationships, learning problem-solving skills, practicing cooperation and altruism, and getting insight and healing), and a core theme (interdependent growth in self-confidence). CONCLUSIONS: The psychosocial group activity provided constructive opportunities for the students to work independently and interdependently as healthcare team members through reflective learning experiences. PMID- 29459195 TI - Cultural adaptation and validation of the Lasater Clinical Judgment Rubric in nursing students in Spain. AB - BACKGROUND: The clinical judgment and decision-making abilities of nurses can influence many health outcomes, hence the importance of addressing these qualities in university studies. In this respect, clinical simulation is a commonly employed teaching method. The evaluation of simulation activities requires standardised instruments, such as the Lasater Clinical Judgment Rubric, which is widely used for this purpose, although a culturally adapted and validated version in Spain is not available. AIMS: To obtain a Spanish culturally adapted and validated version of the rubric for undergraduate students of nursing. DESIGN, PARTICIPANTS AND SETTING: Cultural adaptation and psychometric validation study carried out with undergraduate nursing students in the simulation laboratories at the University of Malaga (Spain). METHODS: A process of translation/back-translation and cultural adaptation was carried out in accordance with international standards. The rubric was empirically evaluated in standardised scenarios with high and medium-fidelity simulators. Each student took part in two different simulation sessions, led by two instructors. In each simulation, the data were collected by two independent observers. RESULTS: 152 observations were obtained from 76 students. The interobserver reliability was high, with an intraclass correlation coefficient of 0.93 (95% CI 0.92-0.95) (p = 0.0001) and Cronbach's alpha of 0.93. According to the confirmatory factor analysis, the fit of the model was satisfactory in all indices, with a chi2/df value of 1.08, GFI 0.96, TLI 0.99, NFI 0.97 and RMSEA 0.24 (90% CI 0.000-0.066). CONCLUSIONS: The rubric obtained is culturally adapted to the Spanish educational context, and is valid and reliable for nursing students. Further prospective studies should be undertaken to evaluate the responsiveness, potential for transfer to clinical practice and cost-benefit ratios of different simulation designs.

AB - BACKGROUND: The evaluation of the level of clinical competence acquired by the student is a complex process that must meet various requirements to ensure its quality. The psychometric analysis of the data collected by the assessment tools used is a fundamental aspect to guarantee the student's competence level. AIM: To conduct a psychometric analysis of an instrument which assesses clinical competence in nursing students at simulation stations with standardized patients in OSCE-format tests. METHOD: The construct of clinical competence was operationalized as a set of observable and measurable behaviors, measured by the newly-created Student Assessment Tool for Standardized Patient Simulations (SAT SPS), which was comprised of 27 items. The categories assigned to the items were 'incorrect or not performed' (0), 'acceptable' (1), and 'correct' (2). PARTICIPANTS: 499 nursing students. Data were collected by two independent observers during the assessment of the students' performance at a four-station OSCE with standardized patients. Descriptive statistics were used to summarize the variables. The difficulty levels and floor and ceiling effects were determined for each item. Reliability was analyzed using internal consistency and inter-observer reliability. The validity analysis was performed considering face validity, content and construct validity (through exploratory factor analysis), and criterion validity. RESULTS: Internal reliability and inter-observer reliability were higher than 0.80. The construct validity analysis suggested a three-factor model accounting for 37.1% of the variance. These three factors were named 'Nursing process', 'Communication skills', and 'Safe practice'. A significant correlation was found between the scores obtained and the students' grades in general, as well as with the grades obtained in subjects with clinical content. CONCLUSIONS: The assessment tool has proven to be sufficiently reliable and valid for the assessment of the clinical competence of nursing students using standardized patients. This tool has three main components: the nursing process, communication skills, and safety management. PMID- 29459197 TI - Student perception of initial transition into a nursing program: A mixed methods research study. AB - BACKGROUND: Transition into undergraduate education programs is stressful and impacts students' well-being and academic achievement. Previous research indicates nursing students experience stress, depression, anxiety, and poor lifestyle habits which interfere with learning. However, nursing students' experience of transition into nursing programs has not been well studied. Incongruence exists between this lack of research and the desire to foster student success. OBJECTIVES: This study analyzed students' experiences of initial transition into a nursing program. DESIGN: An embedded mixed method design. SETTING: A single site of a direct-entry, four year baccalaureate Canadian nursing program. PARTICIPANTS: All first year nursing students enrolled in the fall term of 2016. METHODS: This study combined the Student Adaptation to College Questionnaire (SACQ) with a subset of participants participating in qualitative focus groups. Quantitative data was analyzed using descriptive statistics to identify statistically significant differences in full-scale and subscale scores. Qualitative data was analyzed utilizing thematic analysis. RESULTS: Significant differences were seen between those who moved to attend university and those who did not, with those who moved scoring lower on the Academic Adjustment subscale. Focus group thematic analysis highlighted how students experienced initial transition into a baccalaureate nursing program. Identified themes included reframing supports, splitting focus/finding focus, negotiating own expectations, negotiating others' expectations, and forming identity. These findings form the Undergraduate Nursing Initial Transition (UNIT) Framework. CONCLUSION: Significance of this research includes applications in faculty development and program supports to increase student success in the first year of nursing and to provide foundational success for ongoing nursing practice. PMID- 29459198 TI - The educational impact of web-based and face-to-face patient deterioration simulation programs: An interventional trial. AB - BACKGROUND: There are international concerns relating to the management of patient deterioration. The "failure to rescue" literature identifies that nursing staff miss cues of deterioration and often fail to call for assistance. Simulation-based educational approaches may improve nurses' recognition and management of patient deterioration. OBJECTIVES: To investigate the educational impact of the First2Act web-based (WB) and face-to-face (F2F) simulation programs. DESIGN & SETTING: A mixed methods interventional cohort trial with nursing staff from four Australian hospitals. PARTICIPANTS: Nursing staff working in four public and private hospital medical wards in the State of Victoria. METHODS: In 2016, ward nursing staff (n = 74) from a public and private hospital completed three F2F laboratory-based team simulations with a patient actor in teams of three. 56 nursing staff from another public and private hospital individually completed a three-scenario WB simulation program (First2ActWeb) [A 91% participation rate]. Validated tools were used to measure knowledge (multi choice questionnaire), competence (check-list of actions) and confidence (self rated) before and after the intervention. RESULTS: Both WB and F2F participants' knowledge, competence and confidence increased significantly after training (p <=0.001). Skill performance for the WB group increased significantly from 61% to 74% (p <= 0.05) and correlated significantly with post-test knowledge (p = 0.014). No change was seen in the F2F groups' performance scores. Course evaluations were positive with median ratings of 4/5 (WB) and 5/5 (F2F). The F2F program received significantly more positive evaluations than the WB program (p < 0.05), particularly with regard to quality of feedback. CONCLUSION: WB and F2F simulation are effective education strategies with both programs demonstrating positive learning outcomes. WB programs increase ease of access to training whilst F2F enable the development of tactile hands on skills and teamwork. A combined blended learning education strategy is recommended to enhance competence and patient safety. PMID- 29459199 TI - Nursing students experienced personal inadequacy, vulnerability and transformation during their patient care encounter: A qualitative meta-synthesis. AB - OBJECTIVES: To identify, appraise and synthesize the best available evidence exploring nursing students' experiences of professional patient care encounters in a hospital unit. DESIGN: The Joanna Briggs Institute (JBI) guidelines were followed and a meta-synthesis was conducted. DATA SOURCES: Qualitative research articles were considered for inclusion in the review, and JBI's meta-aggregative approach to synthesizing qualitative evidence was followed. An extensive search for relevant literature was undertaken in scientific databases. REVIEW METHODS: Data were extracted from the included research articles, and qualitative research findings were pooled using the Qualitative Assessment and Review Instrument. This involved categorization of findings on the basis of similarity of meaning and aggregation of these categories to produce a comprehensive set of synthesized findings. RESULTS: A total of five research articles met the inclusion criteria and were included in the review. The review process resulted in 46 subcategories that were aggregated into 13 categories. The categories generated four synthesized findings: personal existence; personal learning and development; being a professional fellow human; and clinical learning environment. CONCLUSIONS: We meta-synthesized that: Nursing students experienced personal inadequacy, vulnerability and a transformation during their patient care encounter. PMID- 29459200 TI - Perceived vulnerability moderates the relations between the use of protective behavioral strategies and alcohol use and consequences among high-risk young adults. AB - Drinking protective behavioral strategies (PBS) have been associated with reductions in alcohol use and alcohol-related consequences in young adults. PBS subscales, Limiting/Stopping (LS), Manner of Drinking (MOD), and Serious Harm Reduction (SHR), have been examined in the literature; LS, MOD, and SHR have mixed support as protective factors. Understanding moderators between PBS and alcohol use and related consequences is an important development in PBS research in order to delineate when and for whom PBS use is effective in reducing harm from alcohol use. Perceptions of vulnerability to negative consequences, included in health-risk models, may be one such moderator. The current study examined whether two types of perceived vulnerability (perceived vulnerability when drinking; perceived vulnerability in uncomfortable/unfamiliar situations) moderated the relations between LS, MOD, SHR strategies and alcohol use and related negative consequences. High-risk young adults (N = 400; 53.75% female) recruited nationally completed measures of PBS, alcohol use and related consequences, and measures of perceived vulnerability. Findings demonstrated that perceived vulnerability when drinking moderated the relations between MOD strategies and alcohol use. The interactions between perceived vulnerability when drinking and PBS did not predict alcohol-related consequences. Perceived vulnerability in unfamiliar/uncomfortable social situations moderated relations between MOD strategies and both alcohol use and related negative consequences; no other significant interactions emerged. Across both perceived vulnerability types and MOD strategies, those with the highest levels of perceived vulnerability and who used MOD strategies the most had the greatest decrements in alcohol use and related negative consequences. Prevention and intervention implications are discussed. PMID- 29459201 TI - Problematic internet use as an age-related multifaceted problem: Evidence from a two-site survey. AB - BACKGROUND AND AIMS: Problematic internet use (PIU; otherwise known as Internet Addiction) is a growing problem in modern societies. There is scarce knowledge of the demographic variables and specific internet activities associated with PIU and a limited understanding of how PIU should be conceptualized. Our aim was to identify specific internet activities associated with PIU and explore the moderating role of age and gender in those associations. METHODS: We recruited 1749 participants aged 18 and above via media advertisements in an Internet-based survey at two sites, one in the US, and one in South Africa; we utilized Lasso regression for the analysis. RESULTS: Specific internet activities were associated with higher problematic internet use scores, including general surfing (lasso beta: 2.1), internet gaming (beta: 0.6), online shopping (beta: 1.4), use of online auction websites (beta: 0.027), social networking (beta: 0.46) and use of online pornography (beta: 1.0). Age moderated the relationship between PIU and role-playing-games (beta: 0.33), online gambling (beta: 0.15), use of auction websites (beta: 0.35) and streaming media (beta: 0.35), with older age associated with higher levels of PIU. There was inconclusive evidence for gender and gender * internet activities being associated with problematic internet use scores. Attention-deficit hyperactivity disorder (ADHD) and social anxiety disorder were associated with high PIU scores in young participants (age <= 25, beta: 0.35 and 0.65 respectively), whereas generalized anxiety disorder (GAD) and obsessive compulsive disorder (OCD) were associated with high PIU scores in the older participants (age > 55, beta: 6.4 and 4.3 respectively). CONCLUSIONS: Many types of online behavior (e.g. shopping, pornography, general surfing) bear a stronger relationship with maladaptive use of the internet than gaming supporting the diagnostic classification of problematic internet use as a multifaceted disorder. Furthermore, internet activities and psychiatric diagnoses associated with problematic internet use vary with age, with public health implications. PMID- 29459203 TI - Comprehensive evaluation on effective leaching of critical metals from spent lithium-ion batteries. AB - Recovery of metals from spent lithium-ion batteries (LIBs) has attracted worldwide attention because of issues from both environmental impacts and resource supply. Leaching, for instance using an acidic solution, is a critical step for effective recovery of metals from spent LIBs. To achieve both high leaching efficiency and selectivity of the targeted metals, improved understanding on the interactive features of the materials and leaching solutions is highly required. However, such understanding is still limited at least caused by the variation on physiochemical properties of different leaching solutions. In this research, a comprehensive investigation and evaluation on the leaching process using acidic solutions to recycle spent LIBs is carried out. Through analyzing two important parameters, i.e. leaching speed and recovery rate of the corresponding metals, the effects of hydrogen ion concentration, acid species and concentration on these two parameters were evaluated. It was found that a leachant with organic acids may leach Co and Li from the cathode scrap and leave Al foil as metallic form with high leaching selectivity, while that with inorganic acids typically leach all metals into the solution. Inconsistency between the leaching selectivity and efficiency during spent LIBs recycling is frequently noticed. In order to achieve an optimal status with both high leaching selectivity and efficiency (especially at high solid-to-liquid ratios), it is important to manipulate the average leaching speed and recovery rate of metals to optimize the leaching conditions. Subsequently, it is found that the leaching speed is significantly dependent on the hydrogen ion concentration and the capability of releasing hydrogen ions of the acidic leachant during leaching. With this research, it is expected to improve understanding on controlling the physiochemical properties of a leaching solution and to potentially design processes for spent LIBs recycling with high industrial viability. PMID- 29459202 TI - Inhibition of non-homologous end joining in Fanconi Anemia cells results in rescue of survival after interstrand crosslinks but sensitization to replication associated double-strand breaks. AB - When Fanconi Anemia (FA) proteins were depleted in human U2OS cells with integrated DNA repair reporters, we observed decreases in homologous recombination (HR), decreases in mutagenic non-homologous end joining (m-NHEJ) and increases in canonical NHEJ, which was independently confirmed by measuring V(D)J recombination. Furthermore, depletion of FA proteins resulted in reduced HR protein foci and increased NHEJ protein recruitment to replication-associated DSBs, consistent with our observation that the use of canonical NHEJ increases after depletion of FA proteins in cycling cells. FA-depleted cells and FA-mutant cells were exquisitely sensitive to a DNA-PKcs inhibitor (DNA-PKi) after sustaining replication-associated double strand breaks (DSBs). By contrast, after DNA interstrand crosslinks, DNA-PKi resulted in increased survival in FA deficient cells, implying that NHEJ is contributing to lethality after crosslink repair. Our results suggest FA proteins inhibit NHEJ, since repair intermediates from crosslinks are rendered lethal by NHEJ. The implication is that bone marrow failure in FA could be triggered by naturally occurring DNA crosslinks, and DNA PK inhibitors would be protective. Since some sporadic cancers have been shown to have deficiencies in the FA-pathway, these tumors should be vulnerable to NHEJ inhibitors with replication stress, but not with crosslinking agents, which could be tested in future clinical trials. PMID- 29459204 TI - The anaerobic digestion of pig carcase with or without sugar beet pulp, as a novel on-farm disposal method. AB - Anaerobic digestion was investigated as a potential method for on-farm disposal of fallen stock (pig carcases), degrading the carcase material to produce biogas and digestate. The effects of feedstock (sugar beet pulp or pig carcase material or a 50:50 mix) and organic loading rate (50 g-TS L-1 or 100 g-TS L-1), during mesophilic (35 degrees C) anaerobic digestion were investigated. Anaerobic digestion was achieved for all experimental treatments, however the pig carcase material at the higher organic loading rate produced the second highest methane yield (0.56 Nm3 kg-VS-1 versus a range of 0.14-0.58 Nm3 kg-VS-1 for other treatments), with the highest percentage of methane in total biogas (61.6% versus a range of 36.1-55.2% for all other treatments). Satisfactory pathogen reduction is a legislative requirement for disposal of carcase material. Pathogens were quantified throughout the anaerobic digestion process. Enterococcus faecalis concentrations decreased to negligible levels (2.8 log10 CFU g-TS-1), whilst Clostridium perfringens levels remained unaffected by treatment throughout the digestion process (5.3 +/- 0.2 log10 CFU g-TS-1). PMID- 29459205 TI - Environmental monitoring of a landfill area through the application of carbon stable isotopes, chemical parameters and multivariate analysis. AB - Leachate produced during an organic matter decomposition process has a complex composition and can cause contamination of surface and groundwaters adjacent to a landfill area. The monitoring of these areas is extremely important for the characterization of the leachate produced and to avoid or mitigate environmental damages. Thus, the present study has the objective of monitoring the area of a Brazilian landfill using conventional parameters (dissolved metals and anions in water) and alternative, stable carbon isotopes parameters (delta13C of dissolved organic and inorganic carbons in water) in addition to multivariate analysis techniques. The use of conventional and alternative parameters together with multivariate analysis showed that cells of the residues are at different phases of stabilization of the organic matter and probably already at C3 of the methanogenic phase of decomposition. In addition, the data showed that organic matter stabilization ponds present in the landfill are efficient and improve the quality of the leachate. Enrichment of the heavy 13C isotope in both surface and groundwater suggested contamination in two sampling sites.

AB - Despite the development of promising direct oral anticoagulants, which are all orthosteric inhibitors, a sizable number of patients suffer from bleeding complications. We have hypothesized that allosterism based on the heparin-binding exosites presents a major opportunity to induce sub-maximal inhibition of coagulation proteases, thereby avoiding/reducing bleeding risk. We present the design of a group of sulfated benzofuran dimers that display heparin-binding site dependent partial allosteric inhibition of thrombin against fibrinogen (DeltaY = 55-75%), the first time that a small molecule (MW < 800) has been found to thwart macromolecular cleavage by a monomeric protease in a controlled manner. The work leads to the promising concept that it should be possible to develop allosteric inhibitors that reduce clotting, but do not completely eliminate it, thereby avoiding major bleeding complications that beset anticoagulants today. PMID- 29459208 TI - Water-soluble polyol-methanofullerenes as mitochondria-targeted antioxidants: Mechanism of action. AB - The mechanism of an antioxidant action of water-soluble polyol - methanofullerenes C60[C9H10O4(OH)4]6 and C60[C13H18O4(OH)4]6 as the mild uncouplers of an oxidative phosphorylation and respiration is postulated. According to this mechanism, hydroxyl group of methanofullerenols can be protonated under excess of protons in the intermembrane space of hyperpolarized mitochondria. Protonation of fullerene derivatives is confirmed by the decrease in their negative Zeta potential in the pH below 5.4. Heavily protonated methanofullerenols become positively charged and move into the mitochondrial matrix. As a consequence, the proton gradient is dissipated, which causes a decrease in mitochondrial transmembrane potential (DeltaPsim) and reduction in ROS production. PMID- 29459209 TI - 7alpha,15-Dihydroxydehydroabietic acid from Pinus koraiensis inhibits the promotion of angiogenesis through downregulation of VEGF, p-Akt and p-ERK in HUVECs. AB - Pinus koraiensis pinecones are considered an undesired waste by-product of the processing of seeds. However, recent studies of the potential anti-tumor effects of the pinecones have led to increasing interest in their chemical constituents. The present study examined the potential antiangiogenic effects of the constituents of pinecones and further characterized their underlying mechanisms of action. Chemical investigation of a water extract of P. koraiensis pinecones led to the isolation and identification of the eight main components including five diterpenoids (1-5), two monoterpenes (6,7) and a phenolic acid (8). The structure of the compounds was determined by spectroscopic analysis of NMR spectra and LC/MS analysis. Of the isolated compounds, 7alpha,15 dihydroxydehydroabietic acid (5) significantly inhibited the promotion of angiogenesis in human umbilical vein endothelial cells (HUVECs). Compound 5 inhibited angiogenesis through downregulation of the VEGF, p-Akt and p-ERK signaling pathways. These results provide experimental evidence of a novel biological activity of 7alpha,15-dihydroxydehydroabietic acid (5) as a potential antiangiogenic substance. This study also suggests that compound 5 could potentially be a useful adjuvant therapeutic substance for cancer prevention and treatment. PMID- 29459211 TI - A new approach to formulating and appraising drug policy: A multi-criterion decision analysis applied to alcohol and cannabis regulation. AB - BACKGROUND: Drug policy, whether for legal or illegal substances, is a controversial field that encompasses many complex issues. Policies can have effects on a myriad of outcomes and stakeholders differ in the outcomes they consider and value, while relevant knowledge on policy effects is dispersed across multiple research disciplines making integrated judgements difficult. METHODS: Experts on drug harms, addiction, criminology and drug policy were invited to a decision conference to develop a multi-criterion decision analysis (MCDA) model for appraising alternative regulatory regimes. Participants collectively defined regulatory regimes and identified outcome criteria reflecting ethical and normative concerns. For cannabis and alcohol separately, participants evaluated each regulatory regime on each criterion and weighted the criteria to provide summary scores for comparing different regimes. RESULTS: Four generic regulatory regimes were defined: absolute prohibition, decriminalisation, state control and free market. Participants also identified 27 relevant criteria which were organised into seven thematically related clusters. State control was the preferred regime for both alcohol and cannabis. The ranking of the regimes was robust to variations in the criterion-specific weights. CONCLUSION: The MCDA process allowed the participants to deconstruct complex drug policy issues into a set of simpler judgements that led to consensus about the results.

The archaeal communities differed across the gradient. Crenarcheota was the most abundant phyla, with Nitrosphaerales and NRPJ as the predominant classes. Euryachaeota was also found across the Cerrado gradient, including the classes Metanocellales and Methanomassiliicoccaceae. PMID- 29459212 TI - Drug affordability-potential tool for comparing illicit drug markets. AB - BACKGROUND: The importance of illicit drug price data and making appropriate adjustments for purity has been repeatedly highlighted for understanding illicit drug markets. The European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) has been collecting retail price data for a number of drug types alongside drug-specific purity information for over 15 years. While these data are useful for a number of monitoring and analytical purposes, they are not without their limitations and there are circumstances where additional adjustment needs to be considered. This paper reviews some conceptual issues and measurement challenges relevant to the interpretation of price data. It also highlights the issues with between-country comparisons of drug prices and introduces the concept of affordability of drugs, going beyond purity-adjustment to account for varying national economies. METHODS: Based on a 2015 European data set of price and purity data across the heroin and cocaine retail markets, the paper demonstrates a new model for drug market comparative analysis; calculation of drug affordability is achieved by applying to purity-adjusted prices 2015 Price Level Indices (PLI, Eurostat). RESULTS: Available data allowed retail heroin and cocaine market comparison for 27 European countries. The lowest and highest unadjusted prices per gram were observed for heroin: in Estonia, Belgium, Greece and Bulgaria (lowest) and Finland, Ireland, Sweden and Latvia (highest); for cocaine: the Netherlands, Belgium and the United Kingdom (lowest) and Turkey, Finland, Estonia and Romania (highest). The affordability per gram of heroin and cocaine when taking into account adjustment for both purity and economy demonstrates different patterns. CONCLUSION: It is argued that purity-adjusted price alone provides an incomplete comparison of retail price across countries. The proposed new method takes account of the differing economic conditions within European countries, thus providing a more sophisticated tool for cross-national comparisons of retail drug markets in Europe. Future work will need to examine other potential uses of the drug affordability tool. LIMITATIONS: The limitations of this measure reflect primarily the limitations of the constituent data; in addition to issues inherent in collecting accurate data on illicit markets, analysis that relies on data collected from multiple countries is susceptible to discrepancies in data collection practices from country to country. PMID- 29459213 TI - Maximal-intensity exercise does not fully restore muscle pyruvate dehydrogenase complex activation after 3 days of high-fat dietary intake. AB - BACKGROUND & AIMS: Exercise activates muscle pyruvate dehydrogenase complex (PDC), but moderate intensity exercise fails to fully activate muscle PDC after high-fat diet [1]. We investigated whether maximal intensity exercise overcomes this inhibition. METHODS: Quadriceps femoris muscle biopsy samples were obtained from healthy males at rest, and after 46 and 92 electrically-evoked maximal intermittent isometric contractions, which were preceded by 3 days of either low- (18%) or high- (69%) isocaloric dietary fat intake (LFD and HFD, respectively). RESULTS: The ratio of PDCa (active form) to total PDCt (fully activated) at rest was 50% less after HFD (0.32 +/- 0.01 vs 0.15 +/- 0.01; P < 0.05). This ratio increased to 0.77 +/- 0.06 after 46 contractions (P < 0.001) and to 0.98 +/- 0.07 after 92 contractions (P < 0.001) in LFD. The corresponding values after HFD were less (0.54 +/- 0.06; P < 0.01 and 0.70 +/- 0.07; P < 0.01, respectively). Resting muscle acetyl-CoA and acetylcarnitine content was greater after HFD than LFD (both P < 0.05), but their rate of accumulation in the former was reduced during contraction. Muscle lactate content after 92 contractions was 30% greater after HFD (P < 0.05). Muscle force generation during contraction was no different between interventions, but HFD lengthened muscle relaxation time (P < 0.05). Daily urinary total carnitine excretion after HFD was 2.5-fold greater than after LFD (P < 0.01). CONCLUSIONS: A bout of maximal intense exercise did not overcome dietary fat-mediated inhibition of muscle pyruvate dehydrogenase complex activation, and was associated with greater muscle lactate accumulation, as a result of lower PDC flux, and increased muscle relaxation time.

AB - Camellia seeds have been traditionally used as oil raw materials in Asia, and are known for a wide spectrum of applications. Oleanane-type triterpene saponins are the major specialised metabolites in Camellia seeds, and more than seventy saponins have been isolated and characterized. These natural compounds have caught much attention due to their various biological and pharmacological activities, including modulation of gastrointestinal system, anti-cancer, anti inflammation, anti-microorganism, antioxidation, neuroprotection, hypolipidemic effects, foaming and detergence, as well as helping the accumulation of pollutants by plants. These compounds have a promising application in medicine, agriculture, industry and environmental protection. The present paper summarized the information from current publications on Camellia seed saponins, with a focus on the advances made in chemical structures, determination methods, bioactivities and toxicity. We hope this article will stimulate further investigations on these compounds. PMID- 29459216 TI - Anti-inflammatory flavone and chalcone derivatives from the roots of Pongamia pinnata (L.) Pierre. AB - A phytochemical study on the roots of Pongamia pinnata (L.) Pierre yielded 52 flavonoids, including four previously undescribed flavone and four previously undescribed chalcone derivatives. The structures of the isolated compounds were determined on the basis of the 1D, 2D NMR, and mass spectroscopic data. The absolute configurations of the compounds were assigned via the specific rotation, Mosher's method, as well as the electronic circular dichroism (ECD) spectra. All the isolates were evaluated for their inhibitory effects on NO production in LPS stimulated BV-2 microglial cells. Ten compounds showed significant inhibitory effects against NO production, comparable to the positive control, dexamethasone. PMID- 29459218 TI - Clinical and Angiographic Predictors of Mortality in Sudden Cardiac Arrest Patients Having Cardiac Catheterisation: A Single Centre Registry. AB - BACKGROUND: Immediate cardiac catheterisation (CC) is recommended in ST-elevation myocardial infarction (STEMI) following sudden cardiac arrest (SCA). Guidelines advise urgent CC for SCA patients without-STEMI, at clinician discretion. We examined the clinical and angiographic factors predicting mortality in SCA patients having CC. METHODS: Consecutive SCA patients having CC at Liverpool Hospital, Sydney (January 2011-September 2015) were retrospectively analysed. Patient data were retrieved from hospital records, and angiographic SYNTAX scores (SS) were quantified online. Independent predictors of mortality were derived using multivariate logistic analysis. RESULTS: The study cohort comprised 104 SCA patients; mean age 61+/-12years, and 79% male. Immediate CC (<2hours post-SCA) was performed in 35% overall. Compared to the without-STEMI subgroup, STEMI patients had more ventricular fibrillation (91 vs 50%; p<0.0001), and higher mean peak serum high-sensitivity troponin-T (8.25+/-14.7 vs 1.97+/-6.13 ug/L; p=0.006); in the context of higher median SS (18 vs 6.5; p=0.002) and target lesion SS (tSS, 10 vs 0; p<0.001). Percutaneous coronary intervention (PCI; 75 vs 23%; p<0.0001) and target vessel revascularisation (11 vs 0%; p=0.005) were more frequent for STEMI. All-cause mortality was 39%, at 1.3+/-1.5years follow-up. Independent mortality predictors were: delayed CC (HR 4.08), serum lactate >7mmol/L (HR 3.47), and tSS (HR 1.05). CONCLUSIONS: Elevated serum lactate, tSS, and delayed CC, were predictive of longer-term mortality in SCA patients having CC. Late CC in patients without-STEMI suggest scope for improvement in real-world systems of care. Closer scrutiny of target lesion complexity may aid prognostication in SCA survivors. PMID- 29459217 TI - Better together: Developmental screening and monitoring best identify children who need early intervention. AB - BACKGROUND: Widely recommended developmental surveillance methods include developmental monitoring (DM) and development screening (DS). Much research has been done on DS, but very little research has compared the effectiveness of DM and DS together. OBJECTIVES: To investigate the relationship between DM and DS in Part C early intervention (EI) service receipt. METHODS: Authors used data from the 2007/2008 and 2011/2012 National Survey of Children's Health (NSCH). Authors report the prevalence of children aged 10 months to 3 years who received (a) DM only, (b) DS only, (c) both DM and DS, and (c) no DM or DS across survey years. Authors compare the odds of EI receipt across these groups. RESULTS: During both periods, estimated EI receipt prevalence was higher for children receiving both DM and DS (8.38% in 2007/2008; 6.47% in 2011/2012) compared to children receiving no DM or DS (1.31% in 2007/2008; 1.92% in 2011/2012), DM alone (2.74% in 2007/2008; 2.70% in 2011/2012), or DS alone (3.59% in 2007/2008; 3.09% in 2011/2012) (for both time frames, p < .05). From 2007/2008 to 2011/2012, the proportion of children receiving DS only and both DM and DS increased, while children receiving DM only and no DM or DS decreased. CONCLUSIONS: Children receiving DM and DS together were more likely to receive EI compared to children receiving DM alone, DS alone, or neither DM nor DS. These findings support the AAP recommendations indicating that DM and DS are complementary strategies for improving early identification and linkage to EI for young children.

AB - In the era of newly introduced hypertension guidelines recommending lower blood pressure (BP) targets for drug-treated hypertensives, the necessity for optimized management of hypertension becomes even more urgent. The concept of home BP guided antihypertensive therapy is for long suggested as a simple and feasible approach to improve BP control rates and optimize the management of hypertension. Home BP-guided antihypertensive therapy is particularly applicable to hypertensives with chronic kidney disease (CKD) for several reasons including the following: (1) difficult-to-control BP and high BP variability in the CKD setting; (2) poor accuracy of office BP in determining hypertension control status and detecting "white-coat" and "masked" hypertension; (3) poor value of routine office BP recordings in predicting the longitudinal progression of target organ damage; and (4) superiority of home BP over office BP recordings in prognosticating the risk of incident end-stage renal disease or death. The concept of home BP-guided antihypertensive therapy is even more relevant for those on hemodialysis, given the high intradialytic and interdialytic BP variability and poor value of conventional peridialytic BP recordings in estimating the actual BP load recorded outside of dialysis with the use of home or ambulatory BP monitoring. Randomized trials comparing home BP-guided antihypertensive therapy versus usual care are warranted to prove the feasibility and effectiveness of this therapeutic approach and convince clinicians for using home BP monitoring as the standard of care when managing hypertension, particularly in people with CKD or end-stage renal disease. PMID- 29459220 TI - Varying blood pressure in children: a diagnostic quandary interpreting the Fourth Report. AB - Fourth Report guidelines on pediatric blood pressure (BP) are not clear when defining hypertension in children as "an average systolic BP and/or diastolic BP >= 95th percentile for gender, age, and height on >= 3 occasions." We aimed to determine the prevalence of pediatric hypertension in a screening population based on two different guideline interpretations. Prevalence of hypertension among 2094 students at four Houston area schools was calculated based on the summation or sustained model definition from Fourth Report guidelines. Summation hypertension definition required the single average of the BPs recorded across three visits to be elevated. Sustained hypertension definition required BP at each of three visits to be elevated. Hypertension prevalence by the summation method was 7%, whereas sustained prevalence was only 3.3%. Nearly a quarter of students had varying BP and were not classifiable by the sustained method but most would be classified as normal or prehypertensive by the summation method. The prevalence of hypertension among adolescents doubled depending on the interpretation of Fourth Report guidelines. Although methods in research studies can be clearly examined on publication of results, it is unknown which interpretation method is being used in clinical practice. PMID- 29459221 TI - Unsung and understudied: plastids involved in secondary growth. AB - Plastids represent the only subcellular compartment where aromatic amino acid precursors for lignin can be synthesized during secondary growth in vascular plants. Despite this, aside from a general shared understanding that plastid localized metabolism occurs during secondary growth, virtually no research has been performed on understanding their biology. Of particular importance will be insight into their ontogeny, morphology and ultrastructure, and (given the complex cytonuclear communication required) their nuclear-encoded and organellar encoded regulation. Updating and integrating this knowledge will contribute to our fundamental understanding of a ubiquitous developmental process in vascular plants, and a major terrestrial carbon sink, as well as carbon-related plant biotechnology. Given available evidence, we propose a new name for a distinct plastid derivative-the 'xyloplast', is required.

PMID- 29459223 TI - Ambulatory practice of dermatologists in Taiwan: A nationwide survey. AB - BACKGROUND: Skin diseases are among the most common public health problems and cause a significant burden. For policymakers and clinicians, comprehensive and detailed information is necessary to better allocate resources needed to care for skin diseases. This study was conducted to characterize the ambulatory practice of dermatologists in Taiwan. METHODS: The study data were drawn from the datasets of Taiwan's National Health Insurance Research Database for 2013, with 623,614 records of ambulatory care visits representing 1/500 of all the claims in Taiwan for 2013. The analysis of these visits included the patient demographics, diagnoses, prescriptions, and procedures. RESULTS: We identified 31,547 visits to dermatologic clinics, which accounted for 5.1% of all the ambulatory care visits in 2013. The three most commonly encountered diseases were contact dermatitis and other eczema, unspecified cause (34.3%, n = 10,811), acne (17.3%, n = 5452), and dermatophytosis (12.9%, n = 4065). Topical glucocorticoids (38.8%, n = 12,248), systemic antihistamines (35.4%, n = 11,172), and systemic antibiotics (15.2%, n = 4809) were the three most commonly prescribed drug categories. Clobetasol, a very potent glucocorticoid, was the most commonly prescribed medication (20.9%, n = 6579). In 22.9% of visits (n = 7248), combined glucocorticoid/antifungal preparations were prescribed. CONCLUSION: This study characterizes the current state of ambulatory dermatologic care in Taiwan. The results raise concerns about the misuse of very potent glucocorticoids and combined glucocorticoid/antifungal preparations in dermatologic practices. PMID- 29459224 TI - Hepatoblastoma incidence in Taiwan: A population-based study. AB - BACKGROUND: The incidence of hepatoblastoma is not well known in Taiwan. The goal of this study was to investigate the incidence rates of hepatoblastoma by age and sex. METHODS: The data of patients with hepatoblastoma diagnosed from 1995 to 2012 were obtained from the population-based Taiwan Cancer Registry. Incidence rates of hepatoblastoma according to sex and age were analyzed. This study employed the published methods of International Agency for Research on Cancer to calculate the age-standardized incidence rates (ASIRs), standard errors, 95% confidence intervals (CIs), and standardized incidence rate ratios (SIRRs). RESULTS: In total, 211 patients were diagnosed with hepatoblastoma during the 18 year study period. The ASIR was 0.76 per million person-years. Hepatoblastoma was predominantly diagnosed in children (n = 184, 87.2%). By contrast, adolescents/adults (n = 10, 4.7%) and elderly people (n = 17, 8.1%) were rarely affected. The incidence peaked at ages 0-4 years with corresponding ASIR of 7.3 per million person-years. A significant male predilection was only found in children and elderly people, with male-to-female SIRRs of 1.23 and 1.89, respectively. During 1995-2012, the overall incidence of hepatoblastoma significantly increased only in children (annual percent change: 7.4%, 95% CI 3.9%-11.1%, p < 0.05) and specifically in boys (annual percent change: 6.5%, 95% CI 1.9%-11.2%, p < 0.05). CONCLUSION: Only 27 patients aged >= 15 years with hepatoblastoma were identified in this study, the existence of adult hepatoblastoma still requires novel molecular tools to elucidate. The association between the upward trend of hepatoblastoma incidence in boys and increased survival of prematurity in Taiwan warrants further investigations. PMID- 29459225 TI - Improvement of overactive bladder symptoms: Is correction of the paravaginal defect in anterior vaginal wall prolapse necessary? AB - BACKGROUND: To explore the relationship between overactive bladder (OAB) symptoms and paravaginal defects (PVDs), and to identify the necessity of PVD repair by transvaginal mesh (TVM) for the treatment of OAB symptoms. METHODS: A retrospective clinical study of 30 women with advanced cystocele with limited apical and posterior vaginal wall prolapse was conducted to identify any changes in OAB symptoms following a single Perigee procedure. Prolapse was assessed using the pelvic organ prolapse quantification (POP-Q) system, and paravaginal defects were identified by sonography. Complete urodynamic examination was performed prior to and one year after operation. All patients completed the overactive bladder questionnaire pre- and postoperatively for a quantitative assessment of OAB symptoms. RESULTS: All patients showed a significant improvement at points Aa and Ba in the POP-Q system. The results of the administered questionnaire revealed statistically significant improvement postoperatively. The difference of OAB symptoms between the group with PVDs and that with central defects was not statistically significant (p = 0.67). Moreover, no statistically significant improvement of OAB symptoms in the group with repaired PVDs was observed postoperatively (p = 0.42). CONCLUSION: Statistical improvements of symptoms exist after Aa and Ba points recovery as evaluated by POP-Q system regardless of PVD existence identified by sonography. Repairing PVD did not show significantly improve the severity of OAB symptoms in objective urodynamic data or subjective questionnaire data. The superiority of TVM in PVD repair to manage OAB symptoms seems not manifest. PMID- 29459226 TI - The Lactobacillus and herpes simplex virus type 2 infection. PMID- 29459228 TI - Factors associated with the implementation of community-based peer-led health promotion programs: A scoping review. AB - Peer education is growing in popularity as a useful health promotion strategy. However, optimal conditions for implementing peer-led health promotion programs (HPPs) remain unclear. This scoping review aimed to describe factors that can influence implementation of peer-led HPPs targeting adult populations. Five databases were searched using the keywords "health promotion/prevention", "implementation", "peers", and related terms. Studies were included if they reported at least one factor associated with the implementation of community based peer-led HPPs. Fifty-five studies were selected for the analysis. The method known as "best fit framework synthesis" was used to analyze the factors identified in the selected papers. Many factors included in existing implementation conceptual frameworks were deemed applicable to peer-led HPPs. However, other factors related to individuals, programs, and implementation context also emerged from the analysis. Based on this synthesis, an adapted theoretical framework was elaborated, grounded in a complex adaptive system perspective and specifying potential mechanisms through which factors may influence implementation of community-based peer-led HPPs. Further research is needed to test the theoretical framework against empirical data. Findings from this scoping review increase our knowledge of the optimal conditions for implementing peer-led HPPs and thereby maximizing the benefits of such programs. PMID- 29459229 TI - Evaluating the implementation of Check & Connect in various school settings: Is intervention fidelity necessarily associated with positive outcomes? AB - There are numerous school dropout prevention programs. However, few of them have undergone a rigorous implementation evaluation to understand their effects. This research presents two studies that evaluated the intervention fidelity and differential effects of Check & Connect (C&C), a targeted school dropout prevention program aimed at promoting student engagement and achievement. A total of 145 elementary school students (Study 1) and 200 secondary school students (Study 2) from two French-Canadian school boards (regional districts grouping elementary and secondary schools) received the C&C intervention for two years. In both studies, a clinical monitoring form was used to compare the intervention fidelity of each program component and active ingredient with what was initially planned. The relation between intervention fidelity and the effects of C&C on student engagement and achievement was analyzed using multiple linear regressions. Overall, the results show that intervention fidelity varies across elementary and secondary schools from one component to another and from one site to another. Furthermore, the association between the fidelity of each component and positive outcomes varies, depending on the implementation site. This evaluation supports the relevance of every component of C&C to favor engagement and academic achievement among at-risk elementary and secondary school students, while suggesting that the importance of certain program components may vary, depending on contextual influences on implementation and outcomes. PMID- 29459227 TI - Hypoxia enhances H2O2-mediated upregulation of hepcidin: Evidence for NOX4 mediated iron regulation. AB - The exact regulation of the liver-secreted peptide hepcidin, the key regulator of systemic iron homeostasis, is still poorly understood. It is potently induced by iron, inflammation, cytokines or H2O2 but conflicting results have been reported on hypoxia. In our current study, we first show that pronounced (1%) and mild (5%) hypoxia strongly induces hepcidin in human Huh7 hepatoma and primary liver cells predominantly at the transcriptional level via STAT3 using two hypoxia systems (hypoxia chamber and enzymatic hypoxia by the GOX/CAT system). SiRNA silencing of JAK1, STAT3 and NOX4 diminished the hypoxia-mediated effect while a role of HIF1alpha could be clearly ruled out by the response to hypoxia-mimetics and competition experiments with a plasmid harboring the oxygen-dependent degradation domain of HIF1alpha. Specifically, hypoxia drastically enhances the H2O2-mediated induction of hepcidin strongly pointing towards an oxidase as powerful upstream control of hepcidin. We finally provide evidences for an efficient regulation of hepcidin expression by NADPH-dependent oxidase 4 (NOX4) in liver cells. In summary, our data demonstrate that hypoxia strongly potentiates the peroxide-mediated induction of hepcidin via STAT3 signaling pathway. Moreover, oxidases such as NOX4 or artificially overexpressed urate oxidase (UOX) can induce hepcidin. It remains to be studied whether the peroxide STAT3-hepcidin axis simply acts to continuously compensate for oxygen fluctuations or is directly involved in iron sensing per se. PMID- 29459231 TI - Contributions of burner, pan, meat and salt to PM emission during grilling. AB - Grilling ground beef meat was conducted in two locations at Nazarbayev University, Kazakhstan. The experiments were designed such that only particles from beef meat were isolated. A similar experimental protocol was applied at both locations. The average particle number and mass emission rates for grilling pure meat itself (excluding particles from pan and burner) were found to be 9.4 * 1012(SD = 7.2 * 1012 particle min-1 and 7.6 * 10 (SD = 6.3 * 10) mg.min-1, respectively. The PM emissions (number and mass) from the burner were found to be negligible compared to the pan and meat emissions. Ultrafine particle (UFP) concentrations from the heated pan itself were comparable to those of grilled meat. However, the particle mass concentrations from the pan itself were negligible. Approximately an hour of continuous heating resulted in zero emissions from the pan. PMID- 29459230 TI - Associations of long-term fine particulate matter exposure with prevalent hypertension and increased blood pressure in older Americans. AB - BACKGROUND: Hypertension is a highly prevalent cardiovascular risk factor. It is possible that air pollution, also an established cardiovascular risk factor, may contribute to cardiovascular disease through increasing blood pressure. Previous studies evaluating associations between air pollution and blood pressure have had mixed results. METHODS: We examined the association between long-term (one-year moving average) air pollutant exposures, prevalent hypertension and blood pressure in 4121 older Americans (57+ years) enrolled in the National Social Life, Health, and Aging Project. We estimated exposures to PM2.5 using spatio temporal models and used logistic regression accounting for repeated measures to evaluate the association between long-term average PM2.5 and prevalence odds of hypertension. We additionally used linear regression to evaluate the associations between air pollutants and systolic, diastolic, mean arterial, and pulse pressures. Health effect models were adjusted for a number of demographic, health and socioeconomic covariates. RESULTS: An inter-quartile range (3.91 MUg/m3) increase in the one-year moving average of PM2.5 was associated with increased: Odds of prevalent hypertension (POR 1.24, 95% CI: 1.11, 1.38), systolic blood pressure (0.93 mm Hg, 95% CI: 0.05, 1.80) and pulse pressure (0.89 mm Hg, 95% CI: 0.21, 1.58). Dose-response relationships were also observed. CONCLUSIONS: PM2.5 was associated with increased odds of prevalent hypertension, and increased systolic pressure and pulse pressure in a cohort of older Americans. These findings add to the growing evidence that air pollution may be an important risk factor for hypertension and perturbations in blood pressure. PMID- 29459232 TI - Arsenic methylation capacity in relation to nutrient intake and genetic polymorphisms in one-carbon metabolism. AB - BACKGROUND: Nutrients and genetic polymorphisms participating in one-carbon metabolism may explain interindividual differences in inorganic arsenic (iAs) methylation capacity, which in turn may account for variations in susceptibility to iAs-induced diseases. OBJECTIVES: 1) To evaluate the association between polymorphisms in five one-carbon metabolism genes (FOLH1 c.223 T > C, MTHFD1 c.1958 G > A, MTHFR c.665 C > T, MTR c.2756 A > G, and MTRR c.66 A > G) and iAs methylation capacity; 2) To assess if previously reported associations between nutrient intake and iAs methylation capacity are modified by those polymorphisms. METHODS: Women (n = 1027) exposed to iAs in Northern Mexico were interviewed. Blood and urine samples were collected. Nutrient dietary intake was estimated using a validated food frequency questionnaire. iAs methylation capacity was calculated from urinary iAs species (iAs, monomethylarsonic acid [MMA] and dimethylarsinic acid [DMA]) measured by high performance liquid chromatography (HPLC-ICP-MS). One polymorphism in each of the five genes evaluated was genotyped by allelic discrimination. Multivariable linear regression models were used to evaluate if genetic polymorphisms modified the associations between iAs methylation capacity parameters and nutrient intake. RESULTS: The median (min max) concentration of total arsenic (TAs) was 20.2 (1.3-2776.0) ug/g creatinine in the study population. Significant interactions for iAs metabolism were only found with FOLH1 c.223 T > C polymorphism and vitamin B12 intake, so that CT and CC genotype carriers had significantly lower %iAs, and higher DMA/iAs with an increased vitamin B12 intake, as compared to carriers of wild-type TT. CONCLUSION: Differences in dietary nutrient intake and genetic variants in one carbon metabolism may jointly influence iAs methylation capacity. Confirmation of these interactions in other populations is warranted. PMID- 29459233 TI - Qualitative and quantitative control of pediatric syrups using Nuclear Magnetic Resonance and chemometrics. AB - Several flavoring and sweetening agents added to excipient of pediatric syrups are not declared in the package leaflet. Therefore, the aim of this study was to develop a non-target, simple, and precise method for qualitative and quantitative evaluation of pediatric syrups using NMR spectroscopy combined with chemometrics. This approach allowed the identification of several added compounds as citric acid, cyclamate, ethanol, glycerol, propylene glycol, saccharin, sorbitol, fructose, glucose, and sucrose. Among the sugared syrups, sucrose was the main carbohydrate with approximately 59.1%, and for sweetened syrups, glycerol with 25.5%. The ethanol was found with highest concentration of 4.0%, approximately. In addition, some syrups presented both sugar and sweetener, which is inconsistent according to the purpose of the addition. Consequently, institutional structures of countries as Brazil that are in charge of public health should put additional compliance pressure on pharmaceutical companies to clearly declare in package leaflet the presence and exact amount of the main compounds (at least) existent in the pediatric excipients. PMID- 29459234 TI - A simple and sensitive HPLC-MS/MS method for quantification of eggmanone in rat plasma and its application to pharmacokinetics. AB - Allosteric phosphodiesterase 4 (PDE4) inhibitors are highly sought after due to their important anti-inflammatory and anti-cancer therapeutic effects. We recently identified Eggmanone, an extraordinarily selective allosteric PDE4 inhibitor displaying favorable drug properties. However, a specific analytic method of Eggmanone in serum and its pharmacokinetics have not been reported yet. In this study, we developed a rapid and sensitive high performance liquid chromatography-mass spectrometric (HPLC-MS/MS) method to determine Eggmanone concentrations in rat plasma. This assay method was validated in terms of specificity, linearity, sensitivity, accuracy, precision, matrix effect, recovery and stability, and was applied to a pharmacokinetic study in rats following intravenous injection of Eggmanone at doses of 1 and 3 mg/kg. The lower limit of quantification (LLOQ) of this assay was 5 ng/mL and the linear calibration curve was acquired with R2 > 0.99 between 5 and 1000 ng/m. The intra-day and inter-day precision was evaluated with the coefficient of variations less than 11.09%, whereas the mean accuracy ranged from 98.38% to 105.13%. The assay method exhibited good recovery and negligible matrix effect. The samples were stable under all the experimental conditions. The plasma concentrations of Eggmanone were detected and quantified over 24 h with the terminal elimination half-live of 3.57 +/- 1.80 h and 5.92 +/- 3.34 h for the low dose (1 mg/kg) and high dose (3 mg/kg) respectively. In summary, the present method provides a robust, fast and sensitive analytical approach for quantification of Eggmanone in plasma and was successfully applied to a pharmacokinetic study in rats. PMID- 29459235 TI - Target and untargeted GC-MS based metabolomic study of mouse optic nerve and its potential in the study of neurological visual diseases. AB - The optic nerve is made of highly specialized neurons and the energetic supply to their axons is crucial due to their great demand. The energy comes basically through the oxidative phosphorylation in the mitochondria, supported by glial cells metabolism. Mitochondrial dysfunction is a shared feature encountered within the optic neuropathies, including Leber's Hereditary Optic Neuropathy, Leigh's Syndrome, or Kjer's syndrome. In an effort to investigate the metabolic alterations produced within the optic nerve in a mutant mouse model of Neurological Visual Disease (NVD), a rapid, robust, and efficient one-single phase extraction methodology has been developed and validated for the GC-MS platform. Once the method was successfully validated for lactic acid and pyruvic acid as markers of an adequate optic nerve function, the protocol was applied to unveil the metabolomic signature of the wild-type mouse optic nerve. Along the chromatographic profile of the optic nerve, 94 peaks were identified and, to our knowledge, for the first time. Afterwards, a targeted metabolomics analysis was performed to quantify lactic acid and pyruvic acid in the NDV mice group (n = 8) and its corresponding wild-type (n = 8). Finally, an untargeted metabolomic study was carried out and univariate and multivariate data analyses showed 34 compounds modified in the optic nerve of the mouse with NVD mutation. Then, the metabolic reaction network of the identified metabolites highlighted alterations in the catabolism of proteins, TCA cycle, and urea cycle, reflecting a mitochondrial energetic dysfunction. Taken together, this metabolomic study has proven to be suited for the study of optic neuropathies. PMID- 29459237 TI - Post-encoding control of working memory enhances processing of relevant information in rhesus monkeys (Macaca mulatta). AB - Working memory is a system by which a limited amount of information can be kept available for processing after the cessation of sensory input. Because working memory resources are limited, it is adaptive to focus processing on the most relevant information. We used a retro-cue paradigm to determine the extent to which monkey working memory possesses control mechanisms that focus processing on the most relevant representations. Monkeys saw a sample array of images, and shortly after the array disappeared, they were visually cued to a location that had been occupied by one of the sample images. The cue indicated which image should be remembered for the upcoming recognition test. By determining whether the monkeys were more accurate and quicker to respond to cued images compared to un-cued images, we tested the hypothesis that monkey working memory focuses processing on relevant information. We found a memory benefit for the cued image in terms of accuracy and retrieval speed with a memory load of two images. With a memory load of three images, we found a benefit in retrieval speed but only after shortening the onset latency of the retro-cue. Our results demonstrate previously unknown flexibility in the cognitive control of memory in monkeys, suggesting that control mechanisms in working memory likely evolved in a common ancestor of humans and monkeys more than 32 million years ago. Future work should be aimed at understanding the interaction between memory load and the ability to control memory resources, and the role of working memory control in generating differences in cognitive capacity among primates. PMID- 29459236 TI - Toward rapid analysis, forecast and discovery of bioactive compounds from herbs by jointly using thin layer chromatography and ratiometric surface-enhanced Raman spectroscopy technique. AB - Conventional isolation and identification of active compounds from herbs have been extensively reported by using various chromatographic and spectroscopic techniques. However, how to quickly discover new bioactive ingredients from natural sources still remains a challenging task due to the interference of their similar structures or matrices. Here, we present a grand approach for rapid analysis, forecast and discovery of bioactive compounds from herbs based on a hyphenated strategy of thin layer chromatography and ratiometric surface-enhanced Raman spectroscopy. The performance of the hyphenated strategy is first evaluated by analyzing four protoberberine alkaloids, berberine (BER), coptisine (COP), palmatine (PAT) and jatrorrhizine (JAT), from a typical herb Coptidis Rhizoma as an example. It has been demonstrated that this coupling method can identify the four compounds by characteristic peaks at 728, 708, 736 and 732 cm-1, and especially discriminate BER and COP (with similar migration distances) by ratiometric Raman intensity (I708/I728). The corresponding limits of detection are 0.1, 0.05, 0.1 and 0.5 MUM, respectively, which are about 1-2 orders of magnitude lower than those of direct observation method under 254 nm UV lamp. Based on these findings, the proposed method further guides forecast and discovery of unknown compounds from traditional Chinese herb Typhonii Rhizoma. Results infer that two trace alkaloids (BER and COP) from the n-butanol extract of Typhonii Rhizoma are found for the first time. Moreover, in vitro experiments manifest that BER can effectively decrease the viability of human glioma U87 cells by inducing cell cycle arrest in a concentration-dependent manner. PMID- 29459238 TI - Encoding of event roles from visual scenes is rapid, spontaneous, and interacts with higher-level visual processing. AB - A crucial component of event recognition is understanding event roles, i.e. who acted on whom: boy hitting girl is different from girl hitting boy. We often categorize Agents (i.e. the actor) and Patients (i.e. the one acted upon) from visual input, but do we rapidly and spontaneously encode such roles even when our attention is otherwise occupied? In three experiments, participants observed a continuous sequence of two-person scenes and had to search for a target actor in each (the male/female or red/blue-shirted actor) by indicating with a button press whether the target appeared on the left or the right. Critically, although role was orthogonal to gender and shirt color, and was never explicitly mentioned, participants responded more slowly when the target's role switched from trial to trial (e.g., the male went from being the Patient to the Agent). In a final experiment, we demonstrated that this effect cannot be fully explained by differences in posture associated with Agents and Patients. Our results suggest that extraction of event structure from visual scenes is rapid and spontaneous. PMID- 29459240 TI - Telehealth for Remote Stroke Management. AB - Stroke is a leading cause of adult disability and the fourth leading cause of death in Canada. Most strokes are ischemic and functional outcome is highly time dependent, making fast diagnosis and treatment initiation crucial. This poses a challenge in vast geographical areas where stroke neurology expertise is only available in urban centres. In this article we review the rationale for telestroke networks and their current implementation in Canada. Telestroke networks enable stroke-specific procedures to be performed by less experienced physicians under the guidance of stroke neurology experts. We also present evidence that the safety and effectiveness of intravenous alteplase in community hospitals in a telestroke network seems to be comparable with that achieved in dedicated stroke centres. It is thus a viable option to guarantee an aging population access to stroke care across large geographic regions with faster treatment and access to more advanced treatment options by means of transfer to a comprehensive centre if necessary. Although telestroke networks have an upfront implementation cost, they can lead to reduced direct and indirect costs for the health care system by reducing days spent in the hospital as well as disability with the need for long-term care. Telestroke networks can also be used for identification and enrollment of patients into emergency stroke trials and thus provide a more representative sample of the population and increase recruitment. Standardization of regional telestroke networks could lead to collaborations with larger data acquisitions for research purposes and quality control in the future. PMID- 29459239 TI - Diabetes, Hypertension, and Cardiovascular Disease: Clinical Insights and Vascular Mechanisms. AB - Hypertension and type 2 diabetes are common comorbidities. Hypertension is twice as frequent in patients with diabetes compared with those who do not have diabetes. Moreover, patients with hypertension often exhibit insulin resistance and are at greater risk of diabetes developing than are normotensive individuals. The major cause of morbidity and mortality in diabetes is cardiovascular disease, which is exacerbated by hypertension. Accordingly, diabetes and hypertension are closely interlinked because of similar risk factors, such as endothelial dysfunction, vascular inflammation, arterial remodelling, atherosclerosis, dyslipidemia, and obesity. There is also substantial overlap in the cardiovascular complications of diabetes and hypertension related primarily to microvascular and macrovascular disease. Common mechanisms, such as upregulation of the renin-angiotensin-aldosterone system, oxidative stress, inflammation, and activation of the immune system likely contribute to the close relationship between diabetes and hypertension. In this article we discuss diabetes and hypertension as comorbidities and discuss the pathophysiological features of vascular complications associated with these conditions. We also highlight some vascular mechanisms that predispose to both conditions, focusing on advanced glycation end products, oxidative stress, inflammation, the immune system, and microRNAs. Finally, we provide some insights into current therapies targeting diabetes and cardiovascular complications and introduce some new agents that may have vasoprotective therapeutic potential in diabetes. PMID- 29459241 TI - The Atherogenic Dyslipidemia Complex and Novel Approaches to Cardiovascular Disease Prevention in Diabetes. AB - Despite the effectiveness of low-density lipoprotein (LDL)-lowering strategies for the treatment of diabetic dyslipidemia, significant residual risk of atherosclerotic cardiovascular disease remains. Residual risk might in part be explained by lipid abnormalities that go beyond LDL cholesterol elevation, collectively termed the "atherogenic dyslipidemia complex (ADC)," consisting of hypertriglyceridemia, elevated small dense LDL particles, reduced high-density lipoprotein cholesterol, and high-density lipoprotein particle numbers, increased remnant lipoproteins, and postprandial hyperlipidemia. In this review, we briefly discuss the pathophysiology of the typical dyslipidemia that occurs in insulin resistant states including obesity, the metabolic syndrome, and type 2 diabetes. Lipid-modifying strategies including lifestyle modification, ezetimibe, statins, fibrates, niacin, and cholesteryl ester transfer protein inhibitors in treating ADC are discussed. With the advent of novel therapies involving antisense oligonucleotides and monoclonal antibodies, new targets can be specifically downregulated to potentially promote lipoprotein clearance or suppress production. We review novel approaches currently undergoing clinical testing and we speculate on their suitability for use in treating ADC for the prevention of atherosclerotic cardiovascular disease. In addition, future targets that might be considered for therapeutic development are discussed. PMID- 29459242 TI - Correlates of disclosure of sexual violence among Kenyan youth. AB - INTRODUCTION: Sexual violence (SV) against children is a global health and human rights issue that can have short and long-term consequences for health and wellbeing. Disclosing SV increases the likelihood that children can access health and protective services and receive psychosocial support. Research in high-income countries has found that child SV survivors are more likely to disclose when they are girls/women, experience fewer SV events, and experience SV perpetrated by a stranger. No studies have examined correlates of SV disclosure in Kenya. OBJECTIVE: The objective of this research was to assess the correlates of disclosing SV among Kenyan youth ages 13-24 who reported an SV experience before age 18. METHODS: In 2010, the Kenya Ministry of Gender, Children and Social Development, the U.S. Centers for Disease Control and Prevention's (CDC) Division of Violence Prevention, the UNICEF Kenya Country Office, and the Kenya National Bureau of Statistics (KNBS) conducted a national survey of violence against children. These data were used to conduct weighted logistic regression analyses to determine which factors were correlated with reporting SV disclosure. RESULTS: Among the 27.8% of girls/women and 14.5% of boys/men who reported SV before age 18, 44.6% of girls/women and 28.2% of boys/men reported to have disclosed the experience. In weighted logistic regression analysis, the odds of disclosure were lower among survivors who were boys/men and among survivors who reported more SV events, and higher when any perpetrator was a family member. CONCLUSION: More context-specific research on SV disclosure among young people is needed globally. PMID- 29459243 TI - Applicability of Lactococcus hircilactis and Lactococcus laudensis as dairy cultures. AB - The aim of this study was to evaluate whether Lactococcus hircilactis and Lactococcus laudensis can be used as starter cultures. To this end, the two lactococci were characterized for traits of technological and functional interest. Tests in milk included growth at 20, 25, 30, and 37 degrees C, flavor production, antioxidant (AO) activity, folate and exopolysaccharide (EPS) production. At 30 degrees C, which resulted the best growth temperature for both strains, Lc. hircilactis and Lc. laudensis lowered the pH of the milk to 4.8 and 5.5, respectively, after 24 h of incubation. Sugar and organic acid composition indicated a higher lactose utilization, coupled with a higher lactate accumulation, by Lc. hircilactis, while galactose was completely consumed by both species. Both strains showed a Cit- phenotype after growth in a selective medium containing citrate as the sole carbon source. Nevertheless, a small amount of citrate was used by both lactococci when grown in milk. The two strains were characterized by a different flavor production, showed high AO activity, and produced small amounts of EPS (~30 mg/L). Lactococcus laudensis showed a weak proteolytic activity while Lc. hircilactis was able to accumulate folate at levels four times higher than uninoculated milk. When the two lactococci were tested as starter cultures in small-scale cheesemaking trials, cheeses resulted of satisfying quality and contained amounts of ethanol, acetic acid, diacetyl and acetoin higher than controls, obtained using a commercial culture. The application of Lc. hircilactis and Lc. laudensis as aromatic cultures in cheesemaking is proposed. PMID- 29459244 TI - Antifungal activity of plant-derived compounds and their synergism against major postharvest pathogens of longan fruit in vitro. AB - The aim of this study was to find alternatives to conventional synthetic fungicides to control postharvest decay of longan fruit. The antifungal potential of thymol, carvacrol and trans-cinnamaldehyde was evaluated against four major longan pathogens, Lasiodiplodia spp., Phomopsis spp., Pestalotiopsis spp. and Geotrichum candidum, using vapor phase and direct contact methods. The vapor phase of all active compounds was more effective on fungal growth than direct contact. A volatile vapor of thymol and carvacrol had strong antifungal activity against the tested fungi, exhibiting minimum inhibitory concentration (MIC) in the range of 40 to 80 mg/L air; trans-cinnamaldehyde showed the least efficiency, with MIC ranging from 80 to 160 mg/L air for G. candidum and Phomopsis spp., while it could not inhibit Lasiodiplodia spp. and Pestalotiopsis spp. at 160 mg/L air. The minimum fungicidal concentration (MFC) of thymol and carvacrol varied from 40 to 80 mg/L air, while trans-cinnamaldehyde completely inhibited the mycelial growth of the tested fungi at higher concentrations. Mycelial growth of all tested fungi decreased with increasing active compound concentration, except for trans-cinnamaldehyde. Thymol proved to be the most effective compound against the four tested fungi, with effective concentration 50 (EC50) of 5.68 +/- 0.59, 6.86 +/- 0.52, 8.27 +/- 0.22 and 9.99 +/- 1.28 mg/L air for Lasiodiplodia spp., Phomopsis spp., Pestalotiopsis spp. and G. candidum, respectively. Fungal growth curves were adequately fitted (0.958 < R2 < 0.996) by a modified Gompertz model. For all tested fungi, the lag phase (lambda) of fungal mycelia exposed to thymol and carvacrol increased, while the maximum colony diameter (A) and maximum growth rate (vm) decreased. A combination of thymol and carvacrol exhibited an antagonistic effect against G. candidum but an indifferent effect against Lasiodiplodia spp., Phomopsis spp. and Pestalotiopsis spp. PMID- 29459245 TI - The Surgical Apgar Score predicts outcomes of emergency abdominal surgeries both in fit and frail older patients. AB - : The Surgical Apgar Score (SAS) is a simple and rapid scoring system predicting postoperative mortality and morbidity. However, it remains unknown whether it might be useful in fit and frail older patients undergoing abdominal emergency surgery. METHODS: Consecutive patients >=65 years, needing emergency abdominal surgery were enrolled in this prospective study. Additionally to the SAS, the G8 screening score was used to determine the frailty status. The logistic regression analysis was conducted investigating the association between the scores and 30 day postoperative outcomes. RESULTS: The study sample comprised 315 older patients (165 female, 150 male) with a median age of 77 (range 65-100) years old. The prevalence of frailty was 60.3%. The most frequent surgical indications were acute cholecystitis, followed by ileus, complicated diverticulitis, ulcer perforation, complication of gastric cancer and other causes. The decreasing SAS was significantly associated with the increasing likelihood of both 30-day postoperative major complications (p < 0.01) and death (p < 0.01) both in fit and frail older patients. Multivariate analyses have identified the G8, frailty screening test, and the SAS score as independent factors that predict postoperative adverse events. The model combining both scores increased the discriminatory ability for 30-day postoperative major morbidity and mortality. CONCLUSION: The SAS confirmed to be a simple and powerful predictor of 30-day postoperative morbidity and mortality both in fit and frail older patients undergoing emergency abdominal surgery. The department allocation algorithm based of the combination of the G8 and the SAS may be considered as an option to improve the outcomes of older patients undergoing abdominal emergency surgery. PMID- 29459246 TI - Breast cancer among older women: The influence of age and cancer stage on survival. AB - PURPOSE OF STUDY: To describe the association between increasing age and survival among women aged over 65 years, diagnosed with breast cancer. MATERIALS AND METHODS: A historical prospective cohort study, comparing 3270 breast cancer patients to 13,163 non cancer age matched controls. Baseline characteristics and cancer data gathered from the Israeli Central Bureau of Statistics (1995), the Israel Cancer Registry (2000-2010). Baseline measurements included age, socioeconomic status. Cancer stage at diagnosis was clustered as stage I, stage II-III and metastatic. Cox Proportional Hazards regression models were used to determine Hazards Ratios (HR) for mortality. RESULTS: Between ages 65-69 and >=85, metastatic disease rose from 3.9% to 23.4% and stage I disease declined from 58.6% to 30.1%. At age 80-84, 50% life expectancy among controls, stage I, and stage II-III disease was 95,92 and 90 months respectively, compared to 2 months for metastatic disease. Compared to controls, between the age 65-69 to >=85, adjusted HR's progressively decreased among subjects with stage I from HR 0.96 (95% CI 0.69-1.33) to 0.60 (95%CI 0.36-1.01), stage II-III from HR 3.26 (95%CI2.58-4.12) to HR 1.60 (95%CI 1.22-2.09), and metastatic disease from HR 57.40 (95%CI 39.56-83.29) to HR 20.76 (95%CI 14.73-29.24). CONCLUSIONS: This study describes the increasingly poor prognosis and short life expectancy observed among women aged >=80 diagnosed with metastatic breast. In contrast, our findings confirm the positive prognosis associated with rising age, among older women presenting with stage I breast cancer, among whom survival was similar, if not slightly better, than non-cancer age matched controls. PMID- 29459247 TI - An exploratory factor analysis of inflammatory and coagulation markers associated with femoral artery atherosclerosis in the San Diego Population Study. AB - BACKGROUND AND AIMS: Several biomarkers of inflammation and coagulation have been implicated in lower extremity atherosclerosis. We utilized an exploratory factor analysis (EFA) to identify distinct factors derived from circulating inflammatory and coagulation biomarkers then examined the associations of these factors with measures of lower extremity subclinical atherosclerosis, including the ankle brachial index (ABI), common and superficial femoral intima-media thickness (IMT), and atherosclerotic plaque presence, burden, and characteristics. METHODS: The San Diego Population Study (SDPS) is a prospective, community-living, multi ethnic cohort of 1103 men and women averaged age 70. Regression analysis was used to assess cross-sectional associations between the identified groupings of biomarkers (factors) and the ABI and femoral artery atherosclerosis measurements. RESULTS: Two biomarker factors emerged from the factor analysis. Factor 1 consisting of C-reactive protein (CRP), interleukin (IL)-6, and fibrinogen was significantly associated with higher odds (OR = 1.99, p < 0.01) of a borderline ABI value (0.91-0.99), while Factor 2 containing D-dimer and pentraxin (PTX)-3 was significantly associated with higher common femoral artery (CFA) IMT (beta = 0.23, p < 0.01) and lower ABI (beta = -0.03, p < 0.01). CONCLUSIONS: Two groupings of biomarkers were identified via EFA of seven circulating biomarkers of inflammation and coagulation. These distinct groups are differentially associated with markers of lower extremity subclinical atherosclerosis. Our findings suggest that high inflammatory and coagulation burden were better markers of more severe lower-extremity disease as indicated by low ABI rather than early atherosclerotic lesion development in the femoral artery. PMID- 29459248 TI - Impact of comorbidity and frailty on prognosis in colorectal cancer patients: A systematic review and meta-analysis. AB - INTRODUCTION: Colorectal cancer (CRC) is largely diagnosed at old age, when comorbidities and frailty are common and might be important prognostic factors of CRC. We aimed to systematically review epidemiological evidence on the prognostic role of comorbidity and frailty in CRC patients. METHODS: We systematically searched the PubMed and Web of Science databases up to August 08, 2017 for observational studies that used a standardized index to assess comorbidity or frailty, investigated and reported odds ratios (OR) or hazard ratios (HR) of their associations with any of the following CRC prognostic outcomes: thirty-day, overall or CRC-specific mortality and disease-free or recurrence-free survival. The study was conducted using standard meta-analysis methodology. RESULTS: Thirty seven cohort studies were identified and included in this review: 35 on comorbidity and 2 on frailty. Of the 35 studies, 13 with comparable methodology were eligible for a meta-analysis. Compared to CRC patients without comorbidity, those with mild/moderate and severe comorbidity had, respectively, a higher risk of 30-day (OR = 1.71; 95% confidence interval (CI): 1.26-2.31 and OR = 2.62; 95% CI: 1.97-3.47), overall (HR = 1.41; 95% CI: 1.23-1.62 and HR = 2.03; 95% CI: 1.76 2.34), and CRC-specific mortality (HR = 1.06; 95% CI: 1.02-1.10 and HR = 1.14; 95% CI: 1.04-1.23). Frail CRC patients showed higher overall mortality than non frail patients (HRrange: 2.60-3.39). CONCLUSIONS: Comorbidity and frailty are strong prognostic factors of survival in CRC patients apart from the commonly considered sociodemographic and tumor characteristics. Comprehensive geriatric assessment might help to optimize care of CRC patients, by improving early identification and management of comorbidities and geriatric syndromes. PMID- 29459249 TI - Associations between social capital and depression: A study of adult twins. AB - Social capital is associated with depression independently of individual-level risk factors. We used a sample of 1586 same-sex twin pairs to test the association between seven measures of social capital and two related measures of neighborhood characteristics with depressive symptoms accounting for uncontrolled selection factors (i.e., genetics and shared environment). All measures of cognitive social capital and neighborhood characteristics were associated with less depressive symptoms in between-twin analysis. However, only measures of cognitive social capital were significantly associated with less depressive symptoms within-pairs. These results demonstrate that cognitive social capital is associated with depressive symptoms free of confounding from genetic and environmental factors shared within twins. PMID- 29459250 TI - Adipose specific disruption of seipin causes early-onset generalised lipodystrophy and altered fuel utilisation without severe metabolic disease. AB - OBJECTIVE: Mutations to the BSCL2 gene disrupt the protein seipin and cause the most severe form of congenital generalised lipodystrophy (CGL). Affected individuals exhibit a near complete loss of white adipose tissue (WAT) and suffer from metabolic disease. Seipin is critical for adipocyte development in culture and mice with germline disruption to Bscl2 recapitulate the effects of BSCL2 disruption in humans. Here we examined whether loss of Bscl2 specifically in developing adipocytes in vivo is sufficient to prevent adipose tissue development and cause all features observed with congenital BSCL2 disruption. METHODS: We generated and characterised a novel mouse model of Bscl2 deficiency in developing adipocytes (Ad-B2(-/-)) using the adipose-specific Adiponectin-Cre line. RESULTS: We demonstrate that Ad-B2(-/-) mice display early onset lipodystrophy, in common with congenital Bscl2 null mice and CGL2 patients. However, glucose intolerance, insulin resistance, and severe hepatic steatosis are not apparent. Food intake and energy expenditure are unchanged, but Ad-B2(-/-) mice exhibit significantly altered substrate utilisation. We also find differential effects of seipin loss between specific adipose depots revealing new insights regarding their varied characteristics. When fed a high-fat diet, Ad-B2(-/-) mice entirely fail to expand adipose mass but remain glucose tolerant. CONCLUSIONS: Our findings demonstrate that disruption of Bscl2 specifically in developing adipocytes is sufficient to cause the early-onset generalised lipodystrophy observed in patients with mutations in BSCL2. However, this significant reduction in adipose mass does not cause the overt metabolic dysfunction seen in Bscl2 knockout mice, even following a high-fat diet challenge. PMID- 29459251 TI - Prolyl carboxypeptidase in Agouti-related Peptide neurons modulates food intake and body weight. AB - OBJECTIVE: Prolyl carboxypeptidase (PRCP) plays a role in the regulation of energy metabolism by inactivating hypothalamic alpha-melanocyte stimulating hormone (alpha-MSH) levels. Although detected in the arcuate nucleus, limited PRCP expression has been observed in the arcuate POMC neurons, and its site of action in regulating metabolism is still ill-defined. METHODS: We performed immunostaining to assess the localization of PRCP in arcuate Neuropeptide Y/Agouti-related Peptide (NPY/AgRP) neurons. Hypothalamic explants were then used to assess the intracellular localization of PRCP and its release at the synaptic levels. Finally, we generated a mouse model to assess the role of PRCP in NPY/AgRP neurons of the arcuate nucleus in the regulation of metabolism. RESULTS: Here we show that PRCP is expressed in NPY/AgRP-expressing neurons of the arcuate nucleus. In hypothalamic explants, stimulation by ghrelin increased PRCP concentration in the medium and decreased PRCP content in synaptic extract, suggesting that PRCP is released at the synaptic level. In support of this, hypothalamic explants from mice with selective deletion of PRCP in AgRP neurons (PrcpAgRPKO) showed reduced ghrelin-induced PRCP concentration in the medium compared to controls mice. Furthermore, male PrcpAgRPKO mice had decreased body weight and fat mass compared to controls. However, this phenotype was sex specific as female PrcpAgRPKO mice show metabolic differences only when challenged by high fat diet feeding. The improved metabolism of PrcpAgRPKO mice was associated with reduced food intake and increased energy expenditure, locomotor activity, and hypothalamic alpha-MSH levels. Administration of SHU9119, a potent melanocortin receptor antagonist, selectively in the PVN of PrcpAgRPKO male mice increased food intake to a level similar to that of control mice. CONCLUSIONS: Altogether, our data indicate that PRCP is released at the synaptic levels and that PRCP in AgRP neurons contributes to the modulation of alpha-MSH degradation and related metabolic control in mice. PMID- 29459252 TI - Multimodal, noninvasive seizure network mapping software: A novel tool for preoperative epilepsy evaluation. AB - BACKGROUND: Despite rigorous preoperative evaluation, epilepsy surgery achieves seizure freedom in only two-thirds of cases. Current preoperative evaluation does not include a detailed network analysis despite the association of network-level changes with epilepsy. OBJECTIVE: We sought to create a software algorithm to map individualized epilepsy networks by combining noninvasive electroencephalography (EEG) source localization and nonconcurrent resting state functional magnetic resonance imaging (rsfMRI). METHODS: Scalp EEG and rsfMRI data were acquired for three sample cases: one healthy control case, one case of right temporal lobe epilepsy, and one case of bitemporal seizure onset. Data from rsfMRI were preprocessed, and a time-series function was extracted. Connection coefficients were used to threshold out spurious connections and model global functional networks in a 3D map. Epileptic discharges were localized using a forward model of cortical mesh dipoles followed by an empirical Bayesian approach of inverse source reconstruction and co-registered with rsfMRI. Co-activating brain regions were mapped. RESULTS: Three illustrative sample cases are presented. In the healthy control case, the software showed symmetrical global connectivity. In the right temporal lobe epilepsy case, asymmetry was found in the global connectivity metrics with a paucity of connectivity ipsilateral to the epileptogenic cortex. The superior longitudinal fasciculus, uncinate fasciculus, and commissural fibers connecting disparate and discontinuous cortical regions involved in the epilepsy network were visualized. In the case with bitemporal lobe epilepsy, global connectivity was symmetric. It showed a network of correlating cortical activity local to epileptogenic tissue in both temporal lobes. The network involved white matter tracks in a similar pattern to those seen in the right temporal case. CONCLUSIONS: This modeling algorithm allows better definition of the global brain network and potentially demonstrates differences in connectivity between an epileptic and a non-epileptic brain. This finding may be useful for mapping cortico-cortical connections representing the putative epilepsy networks. With this methodology, we localized the epileptogenic brain and showed network asymmetry and long-distance cortical co-activation. This software tool is the first to use a multimodal, nonconcurrent, and noninvasive approach to model and visualize the epilepsy network. PMID- 29459253 TI - A novel TaqMan(r) assay for Nosema ceranae quantification in honey bee, based on the protein coding gene Hsp70. AB - Nosema ceranae is now a widespread honey bee pathogen with high incidence in apiculture. Rapid and reliable detection and quantification methods are a matter of concern for research community, nowadays mainly relying on the use of biomolecular techniques such as PCR, RT-PCR or HRMA. The aim of this technical paper is to provide a new qPCR assay, based on the highly-conserved protein coding gene Hsp70, to detect and quantify the microsporidian Nosema ceranae affecting the western honey bee Apis mellifera. The validation steps to assess efficiency, sensitivity, specificity and robustness of the assay are described also. PMID- 29459254 TI - Application of a Monte Carlo method to the uncertainty assessment in in situ gamma-ray spectrometry. AB - In situ gamma-ray spectrometry has since the introduction of portable germanium detectors been a widely used method for the assessment of radionuclide ground deposition activity levels. It is, however, a method that is most often associated with fairly large and, more important, poorly known combined measurement uncertainties. In this work an uncertainty analysis of in situ gamma ray spectrometry in accordance with the Guide to the Expression of Uncertainty in Measurements is presented. The uncertainty analysis takes into account uncertainty contributions from the calibration of the detector system, the assumed activity distribution in soil, soil density, detector height and air density. As a result, measurement results from in situ gamma spectrometry will serve as a better basis for decision-making in e.g. radiological emergencies. PMID- 29459255 TI - Circulation of cosmogenic 22Na using the global monitoring network of the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO). AB - Using a recently published global data set of 22Na and 7Be from the global monitoring network of the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO), atmospheric circulation and stratosphere-troposphere interactions are examined. Cosmogenic 22Na has a half-life well-suited to environmental processes with durations from several months to a decade. Combined with corresponding 7Be observations, these two cosmogenic isotopes form a useful environmental tracer and new radiochronometer to study physical interactions of air masses in the stratosphere and troposphere. PMID- 29459256 TI - Evaluation of data quality at the National Cancer Registry of Ukraine. AB - BACKGROUND: Cancer notification has been mandatory in Ukraine since 1953, with the National Cancer Registry of Ukraine (NCRU) established in 1996. The aim of this study was to provide a comprehensive evaluation of the data quality at the NCRU. METHODS: Qualitative and semi-quantitative methods were used to assess the comparability, completeness, validity and timeliness of cancer incidence data from the NCRU for the period 2002-2012. RESULTS: Cancer registration procedures at the NCRU are in accordance with international standards and recommendations. Semi-quantitative methods suggested the NCRU's data was reasonably complete, although decreases in age-specific incidence and mortality rates in the elderly indicated some missing cases at older ages. The proportion of microscopically verified cases increased from 73.6% in 2002 to 82.3% in 2012, with death certificate-only (DCO) proportions stable at around 0.1% and unknown stage recorded in 9.6% of male and 7.5% of female solid tumours. Timeliness was considered acceptable, with reporting >99% complete within a turn-around time of 15 months. CONCLUSION: While timely reporting of national data reflects the advantages of a mandatory data collection system, a low DCO% and observed age specific declines suggest possible underreporting of incidence and mortality data, particularly at older ages. Overall, the evaluation indicates that the data are reasonably comparable and thus may be used to describe the magnitude of the cancer burden in Ukraine. Given its central role in monitoring and evaluation of cancer control activities, ensuring the sustainability of NCRU operations throughout the process of healthcare system reform is of utmost importance. PMID- 29459257 TI - Effect of comorbidities on the course of multiple sclerosis. AB - OBJECTIVE: The clinical condition of multiple sclerosis (MS) patients depends not only on the course of MS but also on their lifestyle and comorbidities. This study aimed to assess the effect of selected comorbidities, lifestyle-related factors and clinical data available at the time of MS diagnosis, on the disease activity and the disability progression in patients with relapsing-remitting multiple sclerosis (RRMS). PATIENTS AND METHODS: Based on clinical relapses over a period of 12 months of observation and the results of MRI scans, 138 patients with RRMS were qualified into two groups: 'active' or 'stable' course of the disease. Patients from both groups were compared regarding the clinical data determined at diagnosis, comorbidities and lifestyle-related factors. Similar comparisons were carried out between patients with EDSS < 3 vs, patients with EDSS >= 3. RESULTS: No significant differences in comorbidities and lifestyle related data between the stable and active group were detected. Arterial hypertension, hyperlipidemia, higher BMI values, older age and a lower education level, were found more frequently in patients with EDSS >= 3. Oligoclonal bands, multifocal clinical manifestation as the first relapse, higher EDSS score and many T2 MRI lesions at the diagnosis were detected significantly more often in the active group. Motor or brainstem/cerebellum damage symptoms as the first relapse were observed more frequently in patients with EDSS >= 3. CONCLUSIONS: Cardiovascular diseases may exacerbate disability progression in MS patients. Relapses and radiological activity do not depend on chronic comorbidities. Clinical data available at the diagnosis may be useful in forecasting a distant course of MS. PMID- 29459258 TI - Chemical chromatin ubiquitylation. AB - Histone modifications dynamically regulate chromatin structure and function, thereby mediating many processes that require access to DNA. Chemical protein synthesis has emerged as a powerful approach for generating homogeneously modified histone analogues in workable amounts for subsequent incorporation into nucleosome arrays for biochemical, functional and structural studies. This short review focuses on the strength of total chemical protein synthesis and semisynthetic approaches to generate ubiquitylated histones in their native or non-native forms and the utility of these analogues to decode the role of ubiquitylation in epigenetics. PMID- 29459259 TI - DL-mandelic acid intercalated Zn-Al layered double hydroxide: A novel antimicrobial layered material. AB - DL-mandelic acid (MA) has been intercalated into Zn-Al layered double hydroxide (LDH) by an anion-exchange reaction. After intercalation of MA anions, the basal spacing of the LDH increased from 0.75 to 1.46 nm, suggesting that the MA anions were successfully intercalated into the interlayer galleries of the LDH. The structure and the thermal stability of the samples were characterized by XRD, FT IR, TG-DTA. Studies of MA release from ZnAl-MA-LDH in hydrochloric solution (pH = 4) imply that ZnAl-MA-LDH is a better controlled release system than pure MA. Meanwhile, the mechanisms of slow release were assessed by using four commonly kinetic models. Finally, the antimicrobial activity of ZnAl-MA-LDH was tested against two kinds of bacteria and a fungus. The study confirms that the mandelic ions intercalated LDHs have the potential application as a slow release preservative in the future. PMID- 29459260 TI - Preferential adhesion of surface groups of Bacillus subtilis on gibbsite at different ionic strengths and pHs revealed by ATR-FTIR spectroscopy. AB - Adhesion of bacteria onto minerals is a ubiquitous process that plays a central role in many biogeochemical, microbiology and environmental processes in soil and sediment. Although bacterial adhesion onto soil minerals such as phyllosilicates and Fe-oxides have been investigated extensively, little is known about the mechanisms for bacterial attachment onto Al-oxides. Here, we explored the adhesion of Bacillus subtilis onto gibbsite (gamma-AlOOH) under various ionic strengths (1, 10, 50, and 100 mM NaCl) and pHs (pH 4, 7, and 9) by in-situ attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy. The time evolution of the peak intensities of the attached bacteria suggested that the adhesion underwent an initial rapid reaction followed by a slow pseudo first-order kinetic stage. Spectral comparison between the attached and free cells, together with the interaction energy calculated with the Derjaguin, Landau, Verwey, and Overbeek (DLVO) theory and the micro-morphology of bacteria gibbsite complexes, indicated that both electrostatic and chemical (bacterial groups such as phosphate and carboxyl covalently bind to gibbsite) interactions participated in the adhesion processes. Both solution ionic strength (IS) and pH impacted the spectra of attached bacteria, but the peak intensity of different bands changed differently with these two factors, showing a preferential adhesion of surface groups (phosphate, carboxyl, and amide groups) on gibbsite at different conditions. The diverse responses to IS and pH alteration of the forces (chemical bonds, electrostatic attractions, and the hydrophobic interactions) that essentially govern the adhesion might be responsible for the preferential adhesion. These results may help to better understand how bacteria adhere onto soil oxides at molecular scales. PMID- 29459261 TI - The immune response to CMV infection and vaccination in mice, monkeys and humans: recent developments. AB - The immune response to CMV is characterized by extremely large T cell and antibody responses that persist for a lifetime, but do not prevent superinfection with other CMV strains. This makes generation of a vaccine against CMV very difficult, but has facilitated development of CMV-vectored vaccines, which have shown promise in mouse tumor models and in monkey models of infectious disease. The serendipitous use of a mutant rhesus CMV vector for the SIV vaccine elicited extraordinary, CD8 T cell responses restricted by MHCII and non-classical MHCI molecules which apparently provide protection against SIV. CMV-specific CD8 T cell responses in the mouse model are driven by antigen and live out their lives primarily within the intravascular compartment. PMID- 29459262 TI - Soluble endoglin and hypercholesterolemia aggravate endothelial and vessel wall dysfunction in mouse aorta. AB - BACKGROUND AND AIMS: Increased plasma levels of soluble endoglin (sEng) were detected in patients with endothelial dysfunction-related disorders and hypercholesterolemia. In this study, we hypothesized that high levels of sEng accompanied by mild hypercholesterolemia could aggravate endothelial and vessel wall dysfunction and affect endoglin/eNOS signaling in mouse aorta. METHODS: Three-month-old female transgenic mice on CBAxC57BL/6J background, with high levels of sEng (Sol-Eng+high HFD), and their littermates with low levels of sEng (Sol-Eng+low HFD), were fed a high fat diet for six months. Plasma samples were used for biochemical, ELISA and Luminex analyses of total cholesterol, sEng and inflammatory markers. Functional parameters of aorta were assessed with wire myograph 620M. Western blot analyses of membrane endoglin/eNOS signaling and endothelial dysfunction/inflammation markers in aorta were performed. RESULTS: Functional analysis of aorta showed impaired KCl induced vasoconstriction, endothelial-dependent relaxation after the administration of acetylcholine as well as endothelial-independent relaxation induced by sodium nitroprusside in the Sol-Eng+high HFD group compared to the Sol-Eng+low HFD group. Ach-induced vasodilation after administration of l-NAME was significantly higher in the Sol Eng+high HFD group compared to the Sol-Eng+low HFD group. The expression of endoglin, p-eNOS/eNOS, pSmad2/3/Smad2/3 signaling pathway was significantly lower in the Sol-Eng+high HFD group compared to the Sol-Eng+low HFD group. CONCLUSIONS: The results indicate that long-term hypercholesterolemia combined with high levels of sEng leads to the aggravation of endothelial and vessel wall dysfunction in aorta, with possible alterations of the membrane endoglin/eNOS signaling, suggesting that high levels of soluble endoglin might be considered as a risk factor of cardiovascular diseases. PMID- 29459263 TI - Hyperlipidemia induces typical atherosclerosis development in Ldlr and Apoe deficient rats. AB - BACKGROUND AND AIMS: Low-density lipoprotein receptor (Ldlr) and apolipoprotein E (Apoe) knockout (KO) mice have been widely used as animal models of atherosclerosis. However, data suggested that it is difficult to develop typical atherosclerosis in rats. To this end, Ldlr and Apoe KO rats were generated and the potential to develop novel atherosclerosis models was evaluated. METHODS: We established Apoe/Ldlr single and double KO (DKO) rats via the CRISPR/Cas9 system in the same background. Phenotypes of dyslipidemia and atherosclerosis in these KO rats were systematically characterized. RESULTS: Knockout of either gene led to severe dyslipidemia and liver steatosis. Significant atherosclerotic plaques were observed in the abdominal aorta of all mutant rats fed a normal diet for 48 weeks. Western diet greatly aggravated atherosclerosis and fatty liver. In addition, we found mononuclear cell infiltration in early lesions. Increased expression of inflammatory cytokines, as well as macrophage accumulation in lesions of mutants, was observed, indicating that mononuclear cell trafficking and endothelial inflammation affected atherogenesis. Moreover, mutant rats displayed a sex difference profile more similar to humans in which males had heavier plaque burdens than females. CONCLUSIONS: Deficiency of either Ldlr or Apoe genes induced hyperlipidemia, which promoted endothelial inflammation and led to typical atherosclerosis in rats on normal or Western diets. These models display certain advantages, which will benefit future investigations of atherosclerotic pathology and antiatherosclerotic therapeutics. PMID- 29459264 TI - Induction of microRNA-10a using retinoic acid receptor-alpha and retinoid x receptor-alpha agonists inhibits atherosclerotic lesion formation. AB - BACKGROUND AND AIMS: MicroRNA (miR)-10a is a shear-regulated miR with the lowest expression in vascular endothelial cells (ECs) in athero-susceptible regions with oscillatory shear stress (OS). The aim of this study is to elucidate the relationship between EC miR-10a and atherosclerosis and develop a hemodynamics based strategy for atherosclerosis treatment. METHODS: A combination of in vitro flow system and in vivo experimental animals was used to examine the functional roles of EC miR-10a and its clinical applications in atherosclerosis. RESULTS: En face staining showed that EC miR-10a is down-regulated in the inner curvature (OS region) of aortic arch in rats. Co-administration with retinoic acid receptor alpha (RARalpha)- and retinoid X receptor-alpha (RXRalpha)-specific agonists rescued EC miR-10a expression in this OS region. These effects of OS and RARalpha/RXRalpha-specific agonists on EC miR-10a expression were confirmed by the in vitro flow system, and were modulated by the RARalpha-histone deacetylases complex, with the consequent modulation in the downstream GATA6/vascular cell adhesion molecule (VCAM)-1 signaling cascade. Animal studies showed that miR-10a levels are decreased in both aortic endothelium of atherosclerotic lesions and blood plasma from apolipoprotein E-deficient (ApoE-/-) mice. In vivo induction of EC miR-10a by administration of RARalpha/RXRalpha-specific agonists protects ApoE /- mice from atherosclerosis through inhibition of GATA6/VCAM-1 signaling and inflammatory cell infiltration. CONCLUSIONS: Our findings indicate that down regulation of miR-10a in aortic endothelium and blood serum is associated with atherosclerosis, and miR-10a has potential to be developed as diagnostic molecule for atherosclerosis. Moreover, EC miR-10a induction by RARalpha/RXRalpha-specific agonists is a potential hemodynamics-based strategy for atherosclerosis treatment. PMID- 29459265 TI - Sleep characteristics and progression of coronary artery calcification: Results from the Heinz Nixdorf Recall cohort study. AB - BACKGROUND AND AIMS: Sleep characteristics are associated with incident cardiovascular diseases (CVD), but there is a lack of studies on the association between sleep characteristics and incidence/progression of coronary artery calcification (CAC). METHODS: In the Heinz Nixdorf Recall Study, a population based cohort study in Germany, CAC was assessed by electron-beam tomography at baseline and at 5-year follow-up. In an analysis set of 3043 subjects (age at baseline 45-74 years; 47% men), we fitted logistic and linear regression models to assess associations between self-rated sleep characteristics (nocturnal and total sleep duration; napping; various sleep disorders) and CAC incidence/CAC progression. Progression was measured as 5-year progression factor, as categories of absolute CAC change, and additionally characterized as rapid or slow compared to an extrapolation of baseline CAC values. RESULTS: We observed barely any association between sleep characteristics and CAC progression regardless of the chosen statistical approach; associations between sleep and CAC incidence were slightly larger, e.g., the geometric mean of the 5-year CAC progression factor was 6.8% (95% confidence interval: -9.5; 25.9) larger for <=5 h, 2.9% (-7.3; 14.3) larger for 5.1-6.9 h and 7.1% (-2.4; 15.7) smaller for >=7.5 h total sleep compared to 7- <7.5 h total sleep. For subjects with any regular sleep disorder, the geometric mean of the 5-year CAC progression was 3.5% (-4.7; 11.2) smaller compared to subjects without any regular sleep disorder. CONCLUSIONS: In this German cohort study, sleep characteristics were barely associated with CAC progression.

AB - BACKGROUND AND AIMS: Coronary artery calcification (CAC) is common among patients with chronic kidney disease (CKD) and predicts the risk for cardiovascular disease (CVD). We examined the associations of novel risk factors with CAC progression among patients with CKD. METHODS: Among 1123 CKD patients in the Chronic Renal Insufficiency Cohort (CRIC) Study, CAC was measured in Agatston units at baseline and a follow-up visit using electron beam computed tomography or multidetector computed tomography. RESULTS: Over an average 3.3-year follow up, 109 (25.1%) participants without CAC at baseline had incident CAC and 124 (18.0%) participants with CAC at baseline had CAC progression, defined as an annual increase of >=100 Agatston units. After adjustment for established atherosclerotic risk factors, several novel risk factors were associated with changes in CAC over follow-up. Changes in square root transformed CAC score associated with 1 SD greater level of risk factors were -0.20 (95% confidence interval, -0.31 to -0.10; p < 0.001) for estimated glomerular filtration rate, 0.14 (0.02-0.25; p = 0.02) for 24-h urine albumin, 0.25 (0.15-0.34; p < 0.001) for cystatin C, -0.17 (-0.27 to -0.07; p < 0.001) for serum calcium, 0.14 (0.03 0.24; p = 0.009) for serum phosphate, 0.24 (0.14-0.33; p < 0.001) for fibroblast growth factor-23, 0.13 (0.04-0.23; p = 0.007) for total parathyroid hormone, 0.17 (0.07-0.27; p < 0.001) for interleukin-6, and 0.12 (0.02-0.22; p = 0.02) for tumor necrosis factor-alpha. CONCLUSIONS: Reduced kidney function, calcium and phosphate metabolism disorders, and inflammation, independent of established CVD risk factors, may progress CAC among CKD patients. PMID- 29459267 TI - Ankle brachial index and cognitive function among Hispanics/Latinos: Results from the Hispanic Community Health Study/Study of Latinos. AB - BACKGROUND AND AIMS: The Ankle-Brachial index (ABI) is a well-accepted measure of peripheral artery disease (arterial stenosis and stiffness) and has been shown to be associated with cognitive function and disorders; however, these associations have not been examined in Hispanics/Latinos. Therefore, we sought to examine relationships between ABI and cognitive function among diverse middle-age and older Hispanics/Latinos. METHODS: We used cross-sectional data on n = 7991 participants aged 45-74 years, without stroke or coronary heart disease, from the Hispanic Community Health Study/Study of Latinos. Our primary outcome, global cognition (GC), was a continuous composite score of four cognitive domains (verbal learning and memory, verbal fluency, executive function, and mental status). Secondary outcomes were the individual tests representing these domains. The ABI was analyzed continuously and categorically with standard clinical cut points. We tested associations using generalized survey regression models incrementally adjusting for confounding factors. Age, sex, hypertension, diabetes, and dyslipidemia moderations were examined through interactions with the primary exposure. RESULTS: In age, sex, and education adjusted models, continuous ABI had an inverse u-shape association with worse GC. We found similar associations with measures of verbal learning and memory, verbal fluency, executive function, but not with low mental status. The associations were attenuated, but not completely explained, by accounting for the confounders and not modified by age, sex, education, and vascular disease risks. CONCLUSIONS: In addition to being a robust indicator of arterial compromise, our study suggests that abnormal ABI readings may also be useful for early signaling of subtle cognitive deficits. PMID- 29459268 TI - Gene-lifestyle interplay in type 2 diabetes. AB - Type 2 diabetes (T2D) is widespread, affecting the health of hundreds of millions worldwide. The disease results from the complex interplay of lifestyle factors acting on a backdrop of inherited DNA risk variants. Detecting and understanding biomarkers, whether genotypes or other downstream biological features that dictate a person's phenotypic response to different lifestyle exposures, may have tremendous utility in the prevention of T2D. Here, we explore (i) evidence of how human genetic adaptation to diverse local environments might interact with lifestyle factors in T2D, (ii) the key challenges facing the research area of gene*lifestyle interactions in T2D, and (iii) the solutions that might be pursued in future studies. Overall, many preliminary examples of such interactions exist, but none is sufficient to have a major impact on clinical decision making. Future studies, integrating genetics and other biological markers into regulatory networks, are likely to be necessary to facilitate the integration of genomics into lifestyle medicine in T2D. PMID- 29459269 TI - Study on antidepressant activity of chiisanoside in mice. AB - The antidepressant-like effect of chiisanoside from the leaves of Acanthopanax sessiliflorus was evaluated by using mice models of depression, forced swim test (FST) and tail suspension test (TST). The results showed that treatment with chiisanoside at dose of 5.0 mg/kg significantly decreased immobility time in the FST and TST. Pretreatment with haloperidol (a non-selective D2 receptor antagonist), bicuculline (a competitive GABA antagonist) and N-methyl-D-aspartic acid (NMDA, an agonist at the glutamate site) effectively reversed the antidepressant-like effect of chiisanoside (5.0 mg/kg). Moreover, chiisanoside treatment did not change the locomotor activity. And chiisanoside (5.0 mg/kg) also effectively increased the dopamine (DA) and gamma-aminobutyric acid (GABA) levels in mice brains exposed to the FST and TST in the co-treatment groups. Then we designed lipopolysaccharide (LPS)-induced antidepressant behavioral experiment, the results showed that LPS significantly increased immobility duration in the TST and FST. Chiisanoside administration could effectively reduce serum interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) levels; at the same time, the changes of related indexes of oxidative stress are improved, such as superoxide dismutase (SOD) and malondialdehyde (MDA). Moreover, chiisanoside effectively down-regulated brain-derived neurotrophic factor (BDNF), tropomyosin-related kinase B (TrkB) and nuclear factor-kappaB (NF-kappaB) in hippocampal. In conclusion, chiisanoside displayed significant antidepressant like effect, which was probably related to the DAergic, GABAergic and glutamatergic systems. And the mechanism of anti-depressant effect of chiisanoside might be via the alterations of animal behaviors, hippocampus inflammation, oxidative stress and neurotrophy, which might be attributed by the BDNF/TrkB/NF-kappaB pathway. PMID- 29459270 TI - Sparse representation for Lamb-wave-based damage detection using a dictionary algorithm. AB - Lamb waves are being investigated extensively for structural health monitoring (SHM) because of their characteristics of traveling long distances with little attenuation and sensitivity to minor local damage in structures. However, Lamb waves are dispersive, which results in the complex overlap of waveforms in the damage detection applications of the SHM community. This paper proposes a sparse representation strategy based on an l1-norm optimization algorithm for guided Lamb-wave-based inspections. A comprehensive dictionary is designed containing various waveforms under diverse conditions so that the received waveform can be decomposed into a spatial domain for the identification of damage location. Furthermore, the l1-norm optimization algorithm is employed to pursue the sparse solution related to the physical damage location. The functionality of the created dictionary is validated by both metal beam and composite wind turbine experiments. The results indicate a great potential for the proposed sparse representation using a dictionary algorithm, which provides an effective alternative approach for damage detection. PMID- 29459271 TI - A family of manganese complexes containing heterocyclic-based ligands with cytotoxic properties. AB - We describe the synthesis of three new manganese (II) complexes containing the bidentate ligands 2-(1-methyl-3-pyrazolyl)pyridine (pypz-Me) and ethyl 2-(3 (pyridine-2-yl)-1H-pyrazol-1-yl)acetate (pypz-CH2COOEt), with formula [MnX2(pypz Me)2] (X = Cl-1, CF3SO3-2) and [Mn(CF3SO3)2(pypz-CH2COOEt)2] 3. Complexes 1-3 have been characterized through analytical, spectroscopic and electrochemical techniques, as well as by monocrystal X-ray diffraction analysis. The complexes show a six-coordinated Mn(II) ion though different stereoisomers have been isolated for the three compounds. Complexes 1-3, together with the previously described compounds [MnCl2(pypz-H)2] 4, [Mn(CF3SO3)2(pypz-H)2] 5, [Mn(NO3)2(pypz H)2] 6, [MnCl2(H2O)2(pypz-H)2] 7 (pypz-H = 2-(3-pyrazolyl)pyridine) and ([Mn(CF3SO3)2((-)-L)2] 8, ((-)-L = (-)-pinene[5,6]bipyridine), were tested in vitro for cytotoxic activity against NCI-H460 and OVCAR-8 cancer cell lines. The geometry of a specific compound does not seem to influence its activity in a significant extent. However, among the tested compounds those that display hydrophobic substituents on the pyrazole ring and triflate ions as labile ligands show the best antiproliferative properties. Specifically, compound 8 containing the pinene-bipyridine ligand presents an antiproliferative activity similar to that of cisplatin and higher than that of carboplatin, and displays selectivity for tumour cells. Its antiproliferative effect is due to the generation of ROS species that allow the compound to interact with DNA. PMID- 29459272 TI - Reactions of ferric hemoglobin and myoglobin with hydrogen sulfide under physiological conditions. AB - Ferric hemoglobin (metHb) and myoglobin (metMb), present at low levels in vivo, have been recently found to oxidize hydrogen sulfide (H2S) in excess, thus potentially contributing to removal of toxic H2S in blood and heart, respectively. Here, we present a kinetic and thermodynamic study of the reaction of metHb and metMb with H2S under physiological conditions, i.e. at low H2S concentrations and with protein in excess of H2S. We show here that both proteins react with sub-stoichiometric H2S:heme ratios following two processes: a fast reversible binding of H2S to ferric heme that prevails at high H2S and a slow heme reduction to the ferrous state that prevails at low H2S. While these two processes are fast for metMb, H2S-induced heme reduction is slow for metHb and the metHb-H2S complex once formed is therefore relatively stable. We find that metHb binds H2S reversibly and cooperatively with a pH-dependent ligand affinity that is within the physiological range of H2S concentrations found in blood. Stopped-flow kinetics show identical association rate constants for H2S at varying pH, demonstrating that H2S and not HS- enters the ferric heme pocket. Dissociation rates of the metHb-H2S complex increase when decreasing pH, consistent with the pH-dependent affinity. Taken together, these data are consistent with a novel biological role of metHb as a H2S carrier in the blood, in parallel with the oxygen carrier function of the much more abundant ferrous Hb. In contrast, metMb in the heart could participate to redox-signaling involving H2S. PMID- 29459273 TI - New antitumor anthra[2,3-b]furan-3-carboxamides: Synthesis and structure-activity relationship. AB - Chemical modifications of the anthraquinone scaffold are aimed at optimization of this exceptionally productive class of antitumor drugs. In particular, our previously reported anthra[2,3-b]furan-3-carboxamides demonstrated a high cytotoxic potency in cell culture and in vivo. In this study, we expanded our series of anthra[2,3-b]furan-3-carboxamides by modifying the key functional groups and dissected the structure-activity relationship within this chemotype. The majority of new compounds inhibited the growth of mammalian tumor cell lines at submicromolar to low micromolar concentrations. We found that 4,11-hydroxy groups as well as the carbonyl moiety in the carboxamide fragment were critical for cytotoxicity whereas the substituent at the 2-position of anthra[2,3-b]furan was not. Importantly, the new derivatives were similarly potent against wild type cells and their variants resistant to doxorubicin due to P-glycoprotein (Pgp) expression or p53 inactivation. The most cytotoxic derivatives 6 and 9 attenuated plasmid DNA relaxation by topoisomerase 1. Finally, we demonstrated that 6 and 9 at 1 MUM induced intracellular oxidative stress, accumulation in G2/M phase of the cell cycle, and apoptosis in gastric carcinoma cell lines regardless of their p53 status. These results further substantiate the potential of anthra[2,3 b]furan-3-carboxamides as antitumor drug candidates. PMID- 29459274 TI - Design, synthesis and biological evaluation of tetrahydronaphthyridine derivatives as bioavailable CDK4/6 inhibitors for cancer therapy. AB - CDK4/6 pathway is an attractive chemotherapeutic target for antitumor drug discovery and development. Herein, we reported the structure-based design and synthesis of a series of novel tetrahydronaphthyridine analogues as selective CDK4/6 inhibitors. Compound 5 was identified as a hit and then systematically structure optimization study was conducted. These efforts led to compound 28, which exhibited excellent in vitro potencies against CDK4/6 enzymatic activity with high selectivity over CDK1, and against Colo-205 cell growth. The compound demonstrated favorable in vitro metabolic and robust mice pharmacokinetic properties. In Colo-205 xenograft models, compound 28 showed potent tumor growth inhibition with acceptable toxic effects, which could serve as a novel anticancer agent for further preclinical study. PMID- 29459275 TI - Original antileishmanial hits: Variations around amidoximes. AB - In continuation to our previous findings on amidoximes' antiparasitic activities, a new series of 23 original derivatives was designed and obtained by convergent synthesis. First, new terminal alkenes were synthesized by cross-coupling reaction. Then, cyclization was performed between terminal alkenes and beta ketosulfones using manganese(III) acetate reactivity. Twenty-three amidoximes were tested for their in vitro activity against Leishmania amazonensis promastigotes and their toxicity on murine macrophages. Seven of the tested compounds exhibited an antileishmanial activity at lower than 10 MUM with moderate to low toxicity. Six of these molecules showed activity at lower than 10 MUM against promastigotes and toxicity at higher than 50 MUM were selected and evaluated for their activity against intracellular Leishmania amazonensis amastigotes. Modulating chemical substituents in position 2 of dihydrofuran highly influenced their antileishmanial activities. The introduction of a methyl or trifluoromethyl group on the benzene ring of the benzyl group had a positive influence on activity without significantly increasing toxicity (52, 59, 60). PMID- 29459276 TI - Cytotoxicity of eta6-areneruthenium-based molecules to glioblastoma cells and their recognition by multidrug ABC transporters. AB - A new series of amphiphilic eta6-areneruthenium(II) compounds containing phenylazo ligands (group I: compounds 1a, 1b, 2a and 2b) and phenyloxadiazole ligands (group II: compounds 3a, 3b, 4a and 4b) were synthesized and characterized for their anti-glioblastoma activity. The effects of the amphiphilic eta6-areneruthenium(II) complexes on the viability of three human glioblastoma cell lines, U251, U87MG and T98G, were evaluated. The azo-derivative ruthenium complexes (group I) showed high cytotoxicity to all cell lines, whilst most oxadiazole-derivative complexes (group II) were less cytotoxic, except for compound 4a. The cationic complexes 2a, 2b and 4b were more cytotoxic than the neutral complexes. Compounds 2a and 2b caused a significant reduction in the percentage of cells in the G0/G1 phase, with concomitant increases in the G2/M phase and fragmented DNA in the T98G cell line. The eta6-areneruthenium(II) compounds were also tested in cell lines that overexpress the multidrug ABC transporters P-gp, MRP1 and ABCG2. Compounds 2b and 4a were substrates for the P gp protein, with resistance indexes of 8.6 and 1.9, respectively. Compound 2b was also a substrate for ABCG2 and MRP1 proteins, with lower resistance indexes (1.8 and 1.6, respectively). The contribution of multidrug ABC transporters to the cytotoxicity of compound 2b in T98G cells was evidenced, since verapamil (a characteristic inhibitor of MRP1) increased the cytotoxicity of compound 2b at concentrations up to 20 MUmol L-1, whilst GF120918 and Ko143 (specific inhibitors of P-gp and ABCG2, respectively) had no significant effect. In addition, we showed that compound 2b interacts with glutathione (GSH), which could explain its cellular efflux by MRP1. Our results showed that the amphiphilic eta6 areneruthenium(II) complexes are promising anti-glioblastoma compounds, especially compound 2b, which was cytotoxic for all three cell lines, although it is transported by the three main multidrug ABC transporters. PMID- 29459277 TI - Targeting G-quadruplex DNA structures in the telomere and oncogene promoter regions by benzimidazole-carbazole ligands. AB - Recent studies support the idea that G-quadruplex structures in the promoter regions of oncogenes and telomere DNA can serve as potential therapeutic targets in the treatment of cancer. Accordingly, several different types of organic small molecules that stabilize G-quadruplex structures and inhibit telomerase activity have been discerned. Here, we describe the binding of benzimidazole-carbazole ligands to G-quadruplex structures formed in G-rich DNA sequences containing the promoter regions of human c-MYC, c-KIT1, c-KIT2, VEGF and BCL2 proto-oncogenes. The fluorescence spectroscopic data indicate that benzimidazole-carbazole ligands bind and stabilize the G-quadruplexes in the promoter region of oncogenes. The molecular docking studies provide insights into the mode and extent of binding of this class of ligands to the G-quadruplexes formed in oncogene promoters. The high stability of these G-quadruplex structures was validated by thermal denaturation and telomerase-catalyzed extension of the 3' end. Notably, benzimidazole-carbazole ligands suppress the expression of oncogenes in cancer cells in a dose-dependent manner. We anticipate that benzimidazole-carbazole ligands, by virtue of their ability to stabilize G-quadruplex structures in the promoter regions of oncogenes, might reduce the risk of cancer through the loss of function in the proteins encoded by these genes. PMID- 29459278 TI - Alkynyl-containing phenylthiazoles: Systemically active antibacterial agents effective against methicillin-resistant Staphylococcus aureus (MRSA). AB - The promising activity of phenylthiazoles against multidrug-resistant bacterial pathogens, in particular MRSA, has been hampered by their limited systemic applicability, due to their rapid metabolism by hepatic microsomal enzymes, resulting in short half-lives. Here, we investigated a series of phenylthiazoles with alkynyl side-chains that were synthesized with the objective of improving stability to hepatic metabolism, extending the utility of phenylthiazoles from topical applications to treatment of a more invasive, systemic MRSA infections. The most promising compounds inhibited the growth of clinically-relevant isolates of MRSA in vitro at concentrations as low as 0.5 MUg/mL, and exerted their antibacterial effect by interfering with bacterial cell wall synthesis via inhibition of undecaprenyl diphosphate synthase and undecaprenyl diphosphate phosphatase. We also identified two phenylthiazoles that successfully eradicated MRSA inside infected macrophages. In vivo PK analysis of compound 9 revealed promising stability to hepatic metabolism with a biological half-life of ~4.5 h. In mice, compound 9 demonstrated comparable potency to vancomycin, and at a lower dose (20 mg/kg versus 50 mg/kg), in reducing the burden of MRSA in a systemic, deep-tissue infection, using the neutropenic mouse thigh-infection model. Compound 9 thus represents a new phenylthiazole lead for the treatment of MRSA infections that warrants further development. PMID- 29459279 TI - Cyclic peptide inhibitors of lysine-specific demethylase 1 with improved potency identified by alanine scanning mutagenesis. AB - Lysine-specific demethylase 1 (LSD1) is a chromatin-remodeling enzyme that plays an important role in cancer. Over-expression of LSD1 decreases methylation at histone 3 lysine 4, and aberrantly silences tumor suppressor genes. Inhibitors of LSD1 have been designed as chemical probes and potential antitumor agents. We recently reported the cyclic peptide 9, which potently and reversibly inhibits LSD1 (IC50 2.1 MUM; Ki 385 nM). Systematic alanine mutagenesis of 9 revealed residues that are critical for LSD1 inhibition, and these mutated peptides were evaluated as LSD1 inhibitors. Alanine substitution at positions 2, 3, 4, 6 and 11 17 preserved inhibition, while substitution of alanine at positions 8 and 9 resulted in complete loss of activity. Cyclic mutant peptides 11 and 16 produced the greatest LSD1 inhibition, and 11, 16, 27 and 28 increased global H3K4me2 in K562 cells. In addition, 16, 27 and 28 promoted significant increases in H3K4me2 levels at the promoter sites of the genes IGFBP2 and FEZ1. Data from these LSD1 inhibitors will aid in the design of peptidomimetics with improved stability and pharmacokinetics. PMID- 29459280 TI - The moderating impact of childhood adversity profiles and conflict on psychological health and suicidal behaviour in the Northern Ireland population. AB - Childhood adversities are key etiological factors in the onset and persistence of psychopathology. In Northern Ireland the Troubles also impacted on the population's psychological health. This study used data from the Northern Ireland Study of Health and Stress a collaborative epidemiological study which used the WMH-CIDI to assess mental health disorders in a nationally representative sample (Part 2, n = 1986). The aims of the study were to assess co-occurrences of childhood adversities and investigate the impact of adversity profiles and conflict experience on psychopathology and suicidal behaviour. Latent Class Analysis uncovered 3 discrete childhood adversity profiles, a low, medium, and high risk class. Individuals from higher risk adversity profiles displayed significantly increased odds of having psychological problems, with conflict exposure also impacting on psychopathology. However, the study revealed that the impact of conflict exposure on suicidal behaviour was moderated by latent class membership and that some adversity may actually be protective. The findings highlight the need to consider that, while adversity can have a negative impact on psychopathology, a lack of adversity early in life may hinder some people from developing adequate coping strategies. Further research is required to identify adversity patterns and other interacting factors that are protective. PMID- 29459281 TI - Synthesis and evaluation of a novel urea-based 68Ga-complex for imaging PSMA binding in tumor. AB - INTRODUCTION: Prostate specific membrane antigen (PSMA) is a well-established target for diagnostic and therapeutic applications for prostate cancer. It is know that [68Ga]PSMA 11 ([68Ga]Glu-NH-CO-NH-Lys(Ahx)-HBED-CC) is the most well studied PET imaging agent for detecting over expressed PSMA binding sites of tumors in humans. In an effort to provide new agents with improved characteristics for PET imaging, we report a novel [68Ga]-Glu-NH-CO-NH-Lys(Ahx) linker-HBED-CC conjugate with a novel O-(carboxymethyl)-L-tyrosine, as the linker group. METHODS: Radiosynthesis was performed by a direct method. In vitro binding and cell internalization of [68Ga]10 was investigated in PSMA positive LNCaP cell lines. Biodistribution and MicroPET imaging studies were performed in LNCaP tumor bearing mice. RESULTS: In vitro binding to LNCaP cells showed that natGa labeled O-(carboxymethyl)-L-tyrosine conjugate, [natGa]10, displayed excellent affinity and specificity (IC50 = 16.5 nM) a value comparable to that of PSMA 11. In vitro cell binding and internalization showed excellent uptake and retention; [68Ga]10 displayed significantly higher cellular internalization than [68Ga]PSMA 11 (12.5 vs 7.4% ID/106 cells at 1 h). Biodistribution studies in LNCaP tumor-bearing mice exhibited a high specific uptake in PSMA expressing tumors and fast clearance in normal organs (19.7 tumor/blood; 20.7 tumor/muscle at 1 h after iv injection). MicroPET imaging studies in mice confirmed that [68Ga]10 displayed excellent uptake and distinctive tumor localization, which was blocked by iv injection of a competing drug, 2-PMPA. CONCLUSIONS: The preliminary results strongly suggest that [68Ga]10 may be promising candidates as a PET imaging radiotracer for detecting PSMA expression in prostate cancer. PMID- 29459282 TI - Embodiment of social roles and thinness as a form of capital: A qualitative approach towards understanding female obesity disparities in Chile. AB - Obesity in Chile disproportionately affects women of low socioeconomic status (SES). Research has shown that ideals of body size and differences in perceived social pressure for being slim across socioeconomic strata contribute to the social stratification of body size among women in modern societies. Thinness is most valued by high SES women, following western standards of ideal body size. Aiming to understand the link between ideals of body size and SES, this qualitative study explored how 36 Chilean women construct their bodily ideals according to their social position. A purposive sample of women with different profiles with regard to educational attainment, nutritional status and body size (dis)satisfaction was defined, aiming to cover a diverse spectrum of bodily perceptions. Data were collected through semi-structured interviews and approached through a thematic and narrative analysis. Drawing on Bourdieu's concepts of habitus, field, capital and embodiment of the social context, this study explains how ideals of body size and appearance are strongly linked to class-dependent gender roles and social roles. The existing gender and class inequalities in the Chilean social structure have been literally embodied by these women through a 'gendered class habitus'. Compliance with the thin ideal confers women different degrees of power according to their social position in different fields, such as in marriage and on the labour market, which turns thinness into an embodied form of capital. The societal dynamic behind obesity rates cannot be disregarded when approaching possible solutions. Promoting obesity-related lifestyle modification at an individual level might appear an over-simplistic and individualistic approach to a complex social issue. Context oriented interventions that take cultural constructions of gender and social class into account might yield better results in the long term, while advocating for a more equitable society and social justice as a public health concern. PMID- 29459283 TI - Insula mediates heartbeat related effects on visual consciousness. AB - Interoceptive signals, such as the heartbeat, are processed in a network of brain regions including the insular cortex. Recent studies have shown that such signals modulate perceptual and cognitive processing, and that they impact visual awareness. For example, visual stimuli presented synchronously to the heartbeat take longer to enter visual awareness than the same stimuli presented asynchronously to the heartbeat, and this is reflected in anterior insular activation. This finding demonstrated a link between the processing of interoceptive and exteroceptive signals as well as visual awareness in the insular cortex. The advantage for visual stimuli which are asynchronous to the heartbeat to enter visual consciousness may indicate a role for the anterior insula in the suppression of the sensory consequences of cardiac signals. Here, we present data from the detailed investigation of two patients with insular lesions (as well as four patients with non-insular lesions and healthy age matched controls) indicating that a lesion of the anterior insular cortex, but not of other regions, abolished this cardio-visual suppression effect. The present data provide causal evidence for the role of the anterior insula in the integration of internal interoceptive and external sensory signals for visual awareness. PMID- 29459284 TI - Prefrontal mediation of the reading network predicts intervention response in dyslexia. AB - A primary challenge facing the development of interventions for dyslexia is identifying effective predictors of intervention response. While behavioral literature has identified core cognitive characteristics of response, the distinction of reading versus executive cognitive contributions to response profiles remains unclear, due in part to the difficulty of segregating these constructs using behavioral outputs. In the current study we used functional neuroimaging to piece apart the mechanisms of how/whether executive and reading network relationships are predictive of intervention response. We found that readers who are responsive to intervention have more typical pre-intervention functional interactions between executive and reading systems compared to nonresponsive readers. These findings suggest that intervention response in dyslexia is influenced not only by domain-specific reading regions, but also by contributions from intervening domain-general networks. Our results make a significant gain in identifying predictive bio-markers of outcomes in dyslexia, and have important implications for the development of personalized clinical interventions. PMID- 29459285 TI - Evaluation of a rapid DNA process with the RapidHIT(r) ID system using a specialized cartridge for extracted and quantified human DNA. AB - The turn-around time of urgent crime scene DNA samples is often far longer than desired by law enforcement. Crime scene DNA sample processing involves both complex and routine processing steps. Simplification and integration of the routine steps would dramatically improve turn-around time and reduce the risk of operator contamination. Routine DNA extraction and quantitation is readily available. However, PCR amplification and electrophoretic analysis remain largely manual. Rapid DNA Analysis is a hands-free "swab in - profile out" process which consists of automated DNA extraction, amplification, separation, detection, and allele calling without human intervention. RapidHIT(r) 200 and RapidHIT ID are rapid DNA systems developed by IntegenX (Pleasanton, CA) and validated for the use of buccal swabs. A new generation of the RapidHIT sample cartridge for RapidHIT ID has been designed and tested which allows the loading of extracted and quantified DNA. RapidHIT EXT sample cartridge allows a user to generate a forensic DNA profile from less than 250 pg of extracted and quantified DNA in less than 90 min with less than one-minute hands-on time. Once the sample is loaded in the RapidHIT EXT sample cartridge, a DNA profile is produced after amplification, detection and automated data analysis. We report on sensitivity, reproducibility, concordance, DNA mixtures and carryover for EXT sample cartridges pre-loaded with GlobalFiler(r) Express and AmpFLSTR(r) NGM SElectTM Express, (Thermo Fisher Scientific, Waltham, MA) STR chemistries. Purified and quantified DNA from mock crime scene samples were used to demonstrate the utility of these cartridges in an established forensic laboratory. PMID- 29459286 TI - Effects of the inoculations using bacteria producing ACC deaminase on ethylene metabolism and growth of wheat grown under different soil water contents. AB - Crop growth and productivity are often impacted by the increased ethylene content induced by adverse environmental conditions such drought. Inoculations with bacteria producing ACC deaminase is considered as a potential biological approach to improve the growth and tolerance of stressed plants by lowering endogenous ethylene level. In this study, germinated wheat seeds were inoculated using three species of the rhizobacteria, which were isolated from the rhizosphere of wheat growing in dryland, and sown in pots. After three weeks, wheat seedlings were exposed to non-limiting water condition, medium drought and severe drought, respectively, for six weeks. The results showed that, irrespective of rhizobacterial inoculations, decreased soil water contents stimulated wheat ethylene metabolism, which was reflected by the significantly increased activity of ACC synthetase and ACC oxidase, besides an increased content of ACC both in the roots and leaves, and an enhanced capacity of leaves to release ethylene, concomitant with a significant decline in shoot and roots biomass. The inoculations of all three rhizobacterial species under each water condition reduced ACC content in wheat leaves, but effects of the inoculations on ACC synthase and ACC oxidase activity in the leaves and roots, ACC content in the roots, the capacity of leaves to release ethylene, and wheat growth varied with water conditions and bacterial species. Hence, both soil water conditions and rhizobacterial inoculations acted on all the processes of ethylene metabolism, with the former being dominant.

AB - Haberlea rhodopensis is a chlorophyll-retaining resurrection plant, which can survive desiccation to air dry state under both low light and sunny environments. Maintaining the integrity of the membrane during dehydration of resurrection plants is extremely important. In the present study, the diffusion model was improved and used for a first time to evaluate the changes in ion leakage through different cellular compartments upon desiccation of H. rhodopensis and to clarify the reasons for significant increase of electrolyte leakage from dry leaves. The applied diffusion approach allowed us to distinguish the performance of plants subjected to dehydration and subsequent rehydration under different light intensities. Well-hydrated (control) shade plants had lower and slower electrolyte leakage compared to control sun plants as revealed by lower values of phase amplitudes, lower rate constants and ion concentration. In well-hydrated and moderately dehydrated plants (50% relative water content, RWC) ion efflux was mainly due to leakage from apoplast. The electrolyte leakage sharply increased in severely desiccated leaves (8% RWC) from both sun and shade plants mainly due to ion efflux from symplast. After 1 day of rehydration the electrolyte leakage was close to control values, indicating fast recovery of plants. We suggest that the enhanced leakage in air-dried leaves should not be considered as damage but rather as a survival mechanism based on a reversible modification in the structure of cell wall, plasma membrane and alterations in vacuolar system of the cells. However, further studies should be conducted to investigate the changes in cell wall/plasma membrane to support this conclusion.

The signaling pathway that mediates this behavior is largely conserved among prokaryotes, with Escherichia coli chemotaxis system being one of the simplest and the best studied. At the core of this pathway are the arrays of clustered chemoreceptors that detect, amplify and integrate various stimuli. Recent work provided deeper understanding of spatial organization and signal processing by these clusters and uncovered the variety of sensory mechanisms used to detect environmental stimuli. Moreover, studies of bacteria with different lifestyles have led to new insights into the diversity and evolutionary conservation of the chemotaxis pathway, as well as the physiological relevance of chemotactic behavior in different environments. PMID- 29459289 TI - Adhesion and relaxation of a soft elastomer on surfaces with skin like roughness. AB - For designing new skin adhesives, the complex mechanical interaction of soft elastomers with surfaces of various roughnesses needs to be better understood. We systematically studied the effects of a wide set of roughness characteristics, film thickness, hold time and material relaxation on the adhesive behaviour of the silicone elastomer SSA 7-9800 (Dow Corning). As model surfaces, we used epoxy replicas obtained from substrates with roughness ranging from very smooth to skin like. Our results demonstrate that films of thin and intermediate thickness (60 and 160 um) adhered best to a sub-micron rough surface, with a pull-off stress of about 50 kPa. Significant variations in pull-off stress and detachment mechanism with roughness and hold time were found. In contrast, 320 um thick films adhered with lower pull-off stress of about 17 kPa, but were less sensitive to roughness and hold time. It is demonstrated that the adhesion performance of the silicone films to rough surfaces can be tuned by tailoring the film thickness and contact time. PMID- 29459290 TI - Mechanical, bactericidal and osteogenic behaviours of hydrothermally synthesised TiO2 nanowire arrays. AB - The application of orthopaedic implants is associated with risks of bacterial infection and long-term antibiotic therapy. This problem has led to the study of implants with nano-textured surfaces as a method of inhibiting bacterial adhesion and reducing implant failure due to infection. In this research, various nano textured surfaces of TiO2 were synthesised using hydrothermal synthesis, by varying NaOH concentration, reaction time and reaction temperature. Their correlations to mechanical, morphological, bactericidal and osteogenic properties of the surfaces were investigated. It was found that high alkaline concentrations produced large nanowire mesh arrays, while short reaction time and low temperature produced comparatively smaller arrays. The highly dense morphology formed at higher NaOH concentrations has resulted in high elastic modulus and hardness values, compared to surfaces produced at lower NaOH concentrations. Viability tests of the TiO2 nanowire array against gram-positive Staphylococcus aureus cells showed a bactericidal efficiency of 54% and 33% after 3 and 18 h, respectively. This nano-textured surface produces an osteoblast cellular metabolic activity of 71% after 24 h, compared to 67% when exposed to a flat Ti control surface. This preliminary work demonstrates an excellent outcome in producing bactericidal surfaces that promoted metabolic activity of human osteoblast cells for potential use in orthopaedic implants.

PMID- 29459293 TI - Determining the most significant input parameters in models of subendocardial ischaemia and their effect on ST segment epicardial potential distributions. AB - There is considerable interest in simulating ischaemia in the ventricle and its effect on the electrocardiogram, because a better understanding of the connection between the two may lead to improvements in diagnosis of myocardial ischaemia. In this work we studied subendocardial ischaemia, in a simplified half-ellipsoidal bidomain model of a ventricle, and its effect on ST segment epicardial potential distributions (EPDs). We found that the EPD changed as the ischaemic depth increased, from a single minimum (min1) over the ischaemic region to a maximum (max) there, with min1 over the border of the region. Lastly, a second minimum (min2) developed on the opposite side of the ischaemic region, in addition to min1 and max. We replicated these results in a realistic ventricular model and showed that the min1 only case could be found for ischaemic depths of up to around 35% of the ventricular wall. In addition, we systematically examined the sensitivity of EPD parameters, such as the potentials and positions of min1, max and min2, to various inputs to the half-ellipsoidal model, such as fibre rotation angle, ischaemic depth and conductivities. We found that the EPD parameters were not sensitive to the blood or transverse bidomain conductivities and were most sensitive to either ischaemic depth and/or fibre rotation angle. This allowed us to conclude that the asynchronous development of the two minima might provide a way of distinguishing between low and high thickness subendocardial ischaemia, and that this method may well be valid despite variability in the population. PMID- 29459292 TI - Effect of off-plane bifurcation angles of primary bronchi on expiratory flows in the human trachea. AB - BACKGROUND: The human airway is exposed to the development of diverse flow patterns based on differences in its morphological/geometrical parameters across individuals. Although effects of the asymmetry between the right and left main bronchi on airway flows have been investigated in the past, there exists a paucity in terms of studies that focus on the role of stronger physiological asymmetric features, such as off-plane bifurcation angles of primary bronchi, in expiratory flows. METHOD: Computational fluid dynamic techniques have been used to demonstrate presence of Dean-type secondary flows and vortices in the bifurcation region. Formation of a distinctive pattern was observed corresponding to an increase in the off-plane branching angle. An experiment involving 3D printed airways and smoke was also performed to visualize flow patterns and verify simulation results. RESULTS: Good agreement was observed between computational and experimental results. Furthermore, it was revealed that the predicted wall shear stress distribution demonstrated significant changes (with a maximum shear stress increase of 30.7%) compared to conventional airway models that adopt symmetric bifurcation angles. The overall flow demonstrated a swerving motion, which was characterized by tracking the vortex cores (maximum accumulated radial movement of 72.6 degrees ) when they ascended towards the trachea inlet in off-plane airway models. CONCLUSIONS: It was confirmed that off-plane bifurcations in human trachea significantly alter the flow characteristics in expiratory flows. It is expected that the results of this study will provide useful information regarding increasingly advanced patient-specific treatments for respiratory diseases in the trachea.

Oken is used in tropical Africa for the treatment of several diseases such as kidney and urinary disorders. This study was aimed to evaluate the effect of B. pinnatum on arginase II activity and its prevention against renal oxidative damage occasioned by CCl4 in rats. Rats were randomly divided into six groups; group I served as the control, group II served as carbon tetrachloride (CCl4) intoxicated group, group III-V animals were pre treated with silymarin (25 mg/kg body weight), 25 mg/kg body weight aqueous extracts of Bryophyllum pinnatum (AEBP) and 50 mg/kg body weight AEBP, respectively, for 14 days, followed by a single injection of CCl4. Group VI rats received AEBP only (50 mg/kg body weight). Results obtained revealed that CCl4 intoxication significantly increased (p < 0.05) the levels of renal markers (serum urea, creatinine and arginase II) in rats when compared to the control group. Further, oxidative stress status appeared in CCl4-intoxicated rats, as evidence by significant elevation in malondialdehyde (MDA), with concomitant decrease in levels of functional sulfhydryl groups (SH), antioxidant enzymes and nitric oxide in rats' kidney. These adverse changes, due to CCl4 intoxication in rats, were however, prevented by pre-treatment with AEBP leaves (25 and 50 mg/kg body weight). The inhibition of arginase II, as well as increased antioxidant status by AEBP in CCl4-intoxicated rats suggests that B. pinnatum can protect kidney against CCl4-induced oxidative damage. PMID- 29459295 TI - The link between insulin resistance parameters and serum uric acid is mediated by adiposity. AB - BACKGROUND AND AIMS: Conflicting results suggest a link between serum uric acid (SUA), inflammation and glucose/insulin homeostasis; however, the role of adiposity in this relationship is not clear. Therefore, we evaluated the role of different adiposity factors, including central body mass index (BMI), peripheral waist circumference (WC), and visceral adiposity [visceral adipose tissue (apVAT)], on the association between SUA, inflammation and glucose/insulin homeostasis among US adults. METHODS: Data were extracted from the 2005-2010 US National Health and Nutrition Examination Surveys. Overall, 16,502 participants were included in the analysis (mean age = 47.1 years, 48.2% men). Analysis of co variance and "conceptus causal mediation" models were applied, while accounting for survey design. RESULTS: Corrected models showed that subjects with higher SUA levels have a less favorable profile of inflammation and glucose/insulin homeostasis parameters (all p < 0.001). We found that all our potential mediators (BMI, WC and apVAT) had an impact (to various extents) on the link between variables, including serum C-reactive protein (CRP), apolipoprotein-B (apoB), insulin resistance markers, 2-h blood glucose (2hG) and triglyceride, and fasting blood glucose (FBG) (TyG) index (all p < .001), while none of the potential mediators (BMI, apVAT, WC) had an impact on the link between FBG and glycated hemoglobin with SUA (all p > 0.05). We have found that all of our mediators partially mediated the link between inflammation and glucose/insulin homeostasis parameters and SUA. Of note, apVAT fully mediated the association between SUA and 2hG. CONCLUSIONS: By applying advanced statistical techniques, we shed light on the complex link of SUA with inflammation and glucose/insulin homeostasis and quantify the role of adiposity factors in that link. PMID- 29459296 TI - Preservative effect of Asparagus racemosus: A novel additive for bioactive edible films for improved lipid oxidative stability and storage quality of meat products. AB - Asparagus racemosus was used as a bioactive ingredient for the development of a novel calcium alginate edible film with preservative potential for improved lipid oxidative stability and storage quality of meat products. Chevon sausages were used as a model system and were aerobically packaged in the edible films incorporated with A. racemosus viz. T0 (0.0%), T1 (1.0%) and T2 (2.0%) and were stored under refrigerated (4 +/- 1 degrees C) conditions. Products packaged in T1 and T2 edible films exhibited significantly (P < 0.05) lower values for TBARS (mg malonaldehyde/kg), microbial counts (cfu/g) and FFA (% oleic acid) indicating the bioactive properties of the developed films. Significantly (P < 0.05) higher sensory scores were recorded for the products packaged in T1 and T2 films. A. racemosus added antioxidant and antimicrobial properties to the developed films which improved the lipid oxidative stability and storage quality of the model meat product. PMID- 29459297 TI - Perceived naturalness and evoked disgust influence acceptance of cultured meat. AB - Cultured meat could be a more environment- and animal-friendly alternative to conventional meat. However, in addition to the technological challenges, the lack of consumer acceptance could be a major barrier to the introduction of cultured meat. Therefore, it seems wise to take into account consumer concerns at an early stage of product development. In this regard, we conducted two experiments that examined the impact of perceived naturalness and disgust on consumer acceptance of cultured meat. The results of Experiment 1 suggest the participants' low level of acceptance of cultured meat because it is perceived as unnatural. Moreover, informing participants about the production of cultured meat and its benefits has the paradoxical effect of increasing the acceptance of traditional meat. Experiment 2 shows that how cultured meat is described influences the participants' perception. Thus, it is important to explain cultured meat in a nontechnical way that emphasizes the final product, not the production method, to increase acceptance of this novel food. PMID- 29459298 TI - Association of single nucleotide polymorphisms in fat metabolism candidate genes with fatty acid profiles of muscle and subcutaneous fat in heavy pigs. AB - Dietary and organoleptic qualities of pork products are largely influenced by the profiles of fatty acids (FAs) of meat and fat. The objective of this work was to investigate the potential associations between FA profile in subcutaneous adipose (back fat and leg fat) and muscular (longissimus dorsi and biceps femoris) tissues in heavy pigs (n = 129, 9-month-old) with single nucleotide polymorphisms (SNPs) in six candidate genes involved in fat metabolism: Stearoyl-CoA desaturase (SCD), Diacylglycerol acyltransferase 1 and 2 (DGAT1 &DGAT2), Microsomal Triglyceride Transfer Protein (MTTP), Fatty Acid Synthase (FASN) and Heart- fatty acid binding protein (H-FABP). Preliminary results suggest a putative association between MTTP, DGAT2 and FASN and the FA content in both fat and meat, whereas between DGAT1, SCD and H-FABP the association was found in adipose tissue only. However, the effect of the analyzed genes, needs to be verified in a larger and better characterized pig population to support the hypothesized associations with FA content. PMID- 29459299 TI - Association of ultimate pH and stress-related blood variables in cattle. AB - The objective of this study was to investigate the relationship between ultimate pH (pHu) and stress-related blood variables. Of 50 cattle in total, blood samples from 6 cattle which exhibited high (>=6.10) pHu (dark-cutting) were collected, along with the same number of low pHu and intermediate pHu cattle (5.40-5.80; 5.80-6.10, respectively) to determine the concentration of plasma cortisol, glucose, lactate, creatine kinase, lactate dehydrogenase, haptoglobin and serum amyloid A protein. Compared to cattle with low pHu, high pHu cattle showed higher plasma cortisol, glucose, lactate, creatine kinase and lactate dehydrogenase levels at exsanguination. But the concentration of haptoglobin and serum amyloid A protein showed no significant differences among three pH groups. These results imply that measuring plasma cortisol, glucose, lactate, creatine kinase, or lactate dehydrogenase levels at exsanguination may be useful to identify the dark cutting beef condition. PMID- 29459300 TI - Fatty acid composition of intramuscular fat and odour-active compounds of lamb commercialized in northern Spain. AB - Muscle fatty acid composition and odour-active compounds released during cooking were characterized in lamb chops (Longissimus thoracis et lumborum, n = 48) collected at retail level in northern Spain. Lamb samples were classified in two groups according to their 10 t/11 t-18:1 ratio: <=1 (10 t-non-shifted, n = 21) and >1 (10 t-shifted, n = 27). Higher n-3 polyunsaturated fatty acid, vaccenic (11 t-18:1) and rumenic acid (9c,11 t-18:2), and iso-branched chain fatty acid contents were found in non-shifted lamb samples while n-6 polyunsaturated fatty acid, internal methyl-branched chain fatty acid, and 10 t-18:1 contents were greater in shifted samples. Regardless the fatty acid profile differences between lamb sample groups, odour-active compound profile was very similar and mostly affected by the cooking conditions. Overall, the main odour-active compounds of cooked lamb were described as "green", "meaty", "roasted", and "fatty" being methyl pyrazine, methional, dimethyl pyrazine, and dimethyl trisulphide the main odour-active compounds. Aldehydes and alcohols were the most abundant volatiles in all samples, and they were mostly originated from the oxidation of unsaturated fatty acids during cooking. PMID- 29459301 TI - Effect of small molecules on the phase behavior and coacervation of aqueous solutions of poly(diallyldimethylammonium chloride) and poly(sodium 4-styrene sulfonate). AB - HYPOTHESIS: Complex coacervates are capable of easily partitioning solutes within them based on relative affinities of solute-water and solute-polyelectrolyte pairs, as the coacervate phase has low surface tension with water, facilitating the transport of small molecules into the coacervate phase. The uptake of small molecules is expected to influence the physicochemical properties of the complex coacervate, including the hydrophobicity within coacervate droplets, phase boundaries of coacervation and precipitation, solute uptake capacity, as well as the coacervate rheological properties. EXPERIMENTS: Phase behavior of aqueous solutions of poly(diallyldimethylammonium chloride) (PDAC) and poly(sodium 4 styrene sulfonate) (SPS) was investigated in the presence of various concentrations of two different dyes, positively charged methylene blue (MB) or non-charged bromothymol blue (BtB), using turbidity measurements. These materials were characterized with UV-vis spectroscopy, zeta potential measurements, isothermal titration calorimetry (ITC), fluorescence spectroscopy, and dynamic rheological measurements. FINDINGS: The presence of MB or BtB accelerates the coacervation process due to the increased hydrophobicity within coacervates by the addition of MB or BtB. The encapsulated MB or BtB tends to reduce the ionic crosslink density in the PDAC-SPS coacervates, resulting in a much weaker interconnecting network of the PDAC-SPS coacervates. PMID- 29459302 TI - Microbial desalination cell with sulfonated sodium poly(ether ether ketone) as cation exchange membranes for enhancing power generation and salt reduction. AB - Microbial desalination cell (MDC) is a bioelectrochemical system capable of oxidizing organics, generating electricity, while reducing the salinity content of brine streams. As it is designed, anion and cation exchange membranes play an important role on the selective removal of ions from the desalination chamber. In this work, sulfonated sodium (Na+) poly(ether ether ketone) (SPEEK) cation exchange membranes (CEM) were tested in combination with quaternary ammonium chloride poly(2,6-dimethyl 1,4-phenylene oxide) (QAPPO) anion exchange membrane (AEM). Non-patterned and patterned (varying topographical features) CEMs were investigated and assessed in this work. The results were contrasted against a commercially available CEM. This work used real seawater from the Pacific Ocean in the desalination chamber. The results displayed a high desalination rate and power generation for all the membranes, with a maximum of 78.6+/-2.0% in salinity reduction and 235+/-7mWm-2 in power generation for the MDCs with the SPEEK CEM. Desalination rate and power generation achieved are higher with synthesized SPEEK membranes when compared with an available commercial CEM. An optimized combination of these types of membranes substantially improves the performances of MDC, making the system more suitable for real applications. PMID- 29459303 TI - The human skin as a sub-THz receiver - Does 5G pose a danger to it or not? AB - In the interaction of microwave radiation and human beings, the skin is traditionally considered as just an absorbing sponge stratum filled with water. In previous works, we showed that this view is flawed when we demonstrated that the coiled portion of the sweat duct in upper skin layer is regarded as a helical antenna in the sub-THz band. Experimentally we showed that the reflectance of the human skin in the sub-THz region depends on the intensity of perspiration, i.e. sweat duct's conductivity, and correlates with levels of human stress (physical, mental and emotional). Later on, we detected circular dichroism in the reflectance from the skin, a signature of the axial mode of a helical antenna. The full ramifications of what these findings represent in the human condition are still unclear. We also revealed correlation of electrocardiography (ECG) parameters to the sub-THz reflection coefficient of human skin. In a recent work, we developed a unique simulation tool of human skin, taking into account the skin multi-layer structure together with the helical segment of the sweat duct embedded in it. The presence of the sweat duct led to a high specific absorption rate (SAR) of the skin in extremely high frequency band. In this paper, we summarize the physical evidence for this phenomenon and consider its implication for the future exploitation of the electromagnetic spectrum by wireless communication. Starting from July 2016 the US Federal Communications Commission (FCC) has adopted new rules for wireless broadband operations above 24 GHz (5 G). This trend of exploitation is predicted to expand to higher frequencies in the sub-THz region. One must consider the implications of human immersion in the electromagnetic noise, caused by devices working at the very same frequencies as those, to which the sweat duct (as a helical antenna) is most attuned. We are raising a warning flag against the unrestricted use of sub-THz technologies for communication, before the possible consequences for public health are explored. PMID- 29459304 TI - Remediation of contaminated soils by enhanced nanoscale zero valent iron. AB - The use of nanoscale zero valent iron (nZVI) for in situ remediation of soil contamination caused by heavy metals and organic pollutants has drawn great concern, primarily owing to its potential for excellent activity, low cost and low toxicity. This reviews considers recent advances in our understanding of the role of nZVI and enhanced nZVI strategy in the remediation of heavy metals and persistent organic contaminants polluted soil. The performance, the migration and transformation of nZVI affected by the soil physical and chemical conditions are summarized. However, the addition of nZVI inevitably disturbs the soil ecosystem, thus the impacts of nZVI on soil organisms are discussed. In order to further investigate the remediation effect of nZVI, physical, chemical and biological method combination with nZVI was developed to enhance the performance of nZVI. From a high efficient and environmentally friendly perspective, biological method enhanced nZVI technology will be future research needs. Possible improvement of nZVI-based materials and potential areas for further applications in soil remediation are also proposed. PMID- 29459306 TI - Organochlorine concentrations in adipose tissue and survival in postmenopausal, Danish breast cancer patients. AB - BACKGROUND: Several studies have investigated an association between organochlorine-concentrations and breast cancer incidence, whereas few have investigated an association with breast cancer mortality. METHODS: We used Cox Proportional Hazards Models to estimate the association between adipose organochlorine-concentrations and mortality after breast cancer in a survivor cohort of 399 postmenopausal women. During a median follow-up of 16.1 years, 177 women died; 119 from breast cancer. RESULTS: There was a general inverse association with PCB-concentration (e.g. SigmaPCBs: Mortality Rate Ratio (MRR) 0.79, 95% confidence interval (CI) (0.64-0.98) per inter-quartile range (IQR)), and for all pesticides, except beta-Hexachlorocyclohexane, which was not associated with mortality (MRR 1.02(0.87-1.18) per IQR), and dieldrin, which was associated with a significantly increased risk of death (MRR 1.22(1.05-1.41) per IQR). We found an interaction with prognostic factors for all PCBs, confining the inverse association to those with adverse prognostic factors. Results for pesticides suggested a similar, but mostly non-significant interaction. Dieldrin diverged from the general picture by being associated with increased mortality across all strata. CONCLUSION: A higher concentration of PCBs and several organochlorine pesticides may be inversely associated with breast cancer mortality among women with adverse prognostic factors. Further studies are required to investigate if this is a causal association. Dieldrin was associated with a higher mortality, regardless of prognostic factors. IMPACT: This is the first study to investigate an association between organochlorine concentrations in adipose tissue and breast cancer mortality. A prominent finding is a strong interaction with prognostic factors. The unexpected direction of association for most organochlorines encourages further studies of the role of individual metabolism of the organochlorines and a potentially stronger effect of the metabolites on mortality. PMID- 29459305 TI - Ambient air pollution and semen quality. AB - BACKGROUND: Ambient air pollution is associated with systemic increases in oxidative stress, to which sperm are particularly sensitive. Although decrements in semen quality represent a key mechanism for impaired fecundability, prior research has not established a clear association between air pollution and semen quality. To address this, we evaluated the association between ambient air pollution and semen quality among men with moderate air pollution exposure. METHODS: Of 501 couples in the LIFE study, 467 male partners provided one or more semen samples. Average residential exposure to criteria air pollutants and fine particle constituents in the 72 days before ejaculation was estimated using modified Community Multiscale Air Quality models. Generalized estimating equation models estimated the association between air pollutants and semen quality parameters (volume, count, percent hypo-osmotic swollen, motility, sperm head, morphology and sperm chromatin parameters). Models adjusted for age, body mass index, smoking and season. RESULTS: Most associations between air pollutants and semen parameters were small. However, associations were observed for an interquartile increase in fine particulates <=2.5 um and decreased sperm head size, including -0.22 (95% CI -0.34, -0.11) um2 for area, -0.06 (95% CI -0.09, 0.03) um for length and -0.09 (95% CI -0.19, -0.06) um for perimeter. Fine particulates were also associated with 1.03 (95% CI 0.40, 1.66) greater percent sperm head with acrosome. CONCLUSIONS: Air pollution exposure was not associated with semen quality, except for sperm head parameters. Moderate levels of ambient air pollution may not be a major contributor to semen quality. PMID- 29459307 TI - The timeline of blood pressure changes and hemodynamic responses during an experimental noise exposure. AB - BACKGROUND: Noise exposure increases blood pressure and peripheral vascular resistance in both genders in an experimental setting, as previously reported by the authors. OBJECTIVES: The aim of this re-analysis was to present the minute-by minute timeline of blood pressure changes and hemodynamic events provoked by traffic noise in the young and healthy adults. METHODS: The experiment consisted of three 10-min phases: rest in quiet conditions before noise (Leq = 40 dBA), exposure to recorded road-traffic noise (Leq = 89 dBA), and rest in quiet conditions after noise (Leq = 40 dBA). Participants' blood pressure, heart rate, and hemodynamic parameters (cardiac index and total peripheral resistance index) were concurrently measured with a thoracic bioimpedance device. The raw beat-to beat data were collected from 112 participants, i.e., 82 women and 30 men, aged 19-32 years. The timeline of events was created by splitting each experimental phase into ten one-minute intervals (30 intervals in total). Four statistical models were fitted to answer the six study questions what is happening from one minute to another during the experiment. RESULTS: Blood pressure decreased during quiet phase before noise, increased in the first minute of noise exposure and then decreased gradually toward the end of noise exposure, and continued to decline to baseline values after noise exposure. The cardiac index showed a gradual decrease throughout the experiment, whereas total vascular resistance increased steadily during and after noise exposure. CONCLUSIONS: The timeline of events in this 30-min experiment provides insight into the hemodynamic processes underlying the changes of blood pressure before, during and after noise exposure. PMID- 29459308 TI - Air pollution and emergency department visits for respiratory diseases: A multi city case crossover study. AB - Increasing evidence suggests that ambient air pollution is a major risk factor for both acute and chronic respiratory disease exacerbations and emergencies. The objective of this study was to determine the association between ambient air pollutants and emergency department (ED) visits for respiratory conditions in nine districts across the province of Ontario in Canada. Health, air pollutant (PM2.5, NO2, O3, and SO2), and meteorological data were retrieved from April 2004 to December 2011. Respiratory diseases were categorized as: chronic obstructive pulmonary disease (COPD, including bronchiectasis) and acute upper respiratory diseases. A case-crossover design was used to test the associations between ED visits and ambient air pollutants, stratified by sex and season. For COPD among males, positive results were observed for NO2 with lags of 3-6 days, for PM2.5 with lags 1-8, and for SO2 with lags of 4-8 days. For COPD among females, positive results were observed for O3 with lags 2-4 days, and for SO2 among lags of 3-6 days. For upper respiratory disease emergencies among males, positive results were observed for NO2 (lags 5-8 days), for O3, (lags 0-6 days), PM2.5 (all lags), and SO2 (lag 8), and among females, positive results were observed for NO2 for lag 8 days, for O3, PM2.5 among all lags. Our study provides evidence of the associations between short-term exposure to air pollution and increased risk of ED visits for upper and lower respiratory diseases in an environment where air pollutant concentrations are relatively low. PMID- 29459309 TI - Success of mainstream partial nitritation/anammox demands integration of engineering, microbiome and modeling insights. AB - Twenty years ago, mainstream partial nitritation/anammox (PN/A) was conceptually proposed as pivotal for a more sustainable treatment of municipal wastewater. Its economic potential spurred research, yet practice awaits a comprehensive recipe for microbial resource management. Implementing mainstream PN/A requires transferable and operable ways to steer microbial competition as to meet discharge requirements on a year-round basis at satisfactory conversion rates. In essence, the competition for nitrogen, organic carbon and oxygen is grouped into 'ON/OFF' (suppression/promotion) and 'IN/OUT' (wash-out/retention and seeding) strategies, selecting for desirable conversions and microbes. Some insights need mechanistic understanding, while empirical observations suffice elsewhere. The provided methodological R&D framework integrates insights in engineering, microbiome and modeling. Such synergism should catalyze the implementation of energy-positive sewage treatment. PMID- 29459310 TI - Regulation of vitamin D metabolism following disruption of the microbiota using broad spectrum antibiotics. AB - Vitamin D, 25hydroxyvitamin D (25D), and 24,25dihydroxyvitamin D (24,25D) were measured before and after broad spectrum antibiotic (Abx) treatment for 2 wks. Abx treatments increased 25D and 24,25D levels suggesting that the microbiota or Abx were altering vitamin D metabolism. Increased 25D, but not 24,25D, following Abx treatments were found to be dependent on toll like receptor signaling. Conversely, the effects of Abx on 24,25D levels required that the vitamin D receptor (VDR) be expressed in tissues outside of the hematopoietic system (kidney) and not the immune system. Fibroblast growth factor (FGF)23 increased following Abx treatment and the effect of Abx treatment on FGF23 (like the effect on 24,25D) was not present in VDR knockout (KO) mice. The Abx mediated increase in 24,25D was due to changes to the endocrine regulation of vitamin D metabolism. Conversely, 25D levels went up with Abx treatment of the VDR KO mice. Host sensing of microbial signals regulates the levels of 25D in the host. PMID- 29459311 TI - Effect of hyaluronic acid hydrogels containing astrocyte-derived extracellular matrix and/or V2a interneurons on histologic outcomes following spinal cord injury. AB - One reason for the lack of regeneration, and poor clinical outcomes, following central nervous system (CNS) injury is the formation of a glial scar that inhibits new axon growth. In addition to forming the glial scar, astrocytes have been shown to be important for spontaneous SCI recovery in rodents, suggesting some astrocyte populations are pro-regenerative, while others are inhibitory following injury. In this work, the effect of implanting hyaluronic acid (HA) hydrogels containing extracellular matrix (ECM) harvested from mouse embryonic stem cell (mESC)-derived astrocytes on histologic outcomes following SCI in rats was explored. In addition, the ability of HA hydrogels with and without ECM to support the transplantation of mESC-derived V2a interneurons was tested. The incorporation of ECM harvested from protoplasmic (grey matter) astrocytes, but not ECM harvested from fibrous (white matter) astrocytes, into hydrogels was found to reduce the size of the glial scar, increase axon penetration into the lesion, and reduce macrophage/microglia staining two weeks after implantation. HA hydrogels were also found to support transplantation of V2a interneurons and the presence of these cells caused an increase in neuronal processes both within the lesion and in the 500 MUm surrounding the lesion. Overall, protoplasmic mESC derived astrocyte ECM showed potential to treat CNS injury. In addition, ECM:HA hydrogels represent a novel scaffold with beneficial effects on histologic outcomes after SCI both with and without cells.

AB - The drug resistant bacteria and textile contaminations of water cause different sever health problem throughout the world. To overcome this issue, new environmental benign materials and methods are needed. Plant metabolites directed synthesis of nanoparticles is considered eco-friendly and easy in synthesis. Therefore, it was explicit for the synthesis of AgNPs. The prepared AgNPs were evaluated for antibacterial, antioxidant, photo-catalytic and electrochemical degradation properties as well as toxicity of degradation products on aquatic life. X-Ray Photoelectron Spectroscopy (XPS) has been used for analyzing the surface chemistry of prepared AgNPs. The particle size determines the interaction of nanoparticles with pathogens. Both Gram positive and negative bacteria (Escherichia coli and Staphylococcus areous) are used to determine the anti microbial potency of the green synthesized AgNPs. The synthesized silver nanoparticles showed significant anti-bacterial applications against B. subtilus and S. aureus. The anti-oxidant applications of AgNPs also studied on comparison with vitamin C. The toxicity of the phenolic Azo dyes (PDA) has been studied against Fish, Daphnia and Green Algae. The electrode potential was studied in the electrochemical redox reaction of hydroxy phenol in aqueous media. Simple electrolyte was used to determine the current efficiency. For the stability of electrode multi cyclic voltammetry was also studied during redox reaction, which showed stability under the potential 0.4 to 0.2 V.

AB - Recent studies showed that the photothermal therapy can be effectively used for the targeted cancerous cells destruction. Hence, in the present study, benzimidazole based metal organic complex nanoparticles, dichloro cobalt(II) bis benzimidazole (Co-BMZ) and dichloro copper(II) bis-benzimidazole (Cu-BMZ), were synthesized by reprecipitation method and their anti-cancer activity by means of photothermal effect has been studied. Transmission electron microscopy analysis shows that the particle size of Cu-BMZ is ~100 nm and Co-BMZ is in the range between 100 and 400 nm. Zeta potential analysis ensures the stability of the synthesized nanoparticles. It is found that the nonlinear absorption of the nanoparticles increases with increase in laser power intensity. Phototoxicity of human lung cancer (A549) and the normal mouse embryonic fibroblast (NIH-3T3) cells was studied using a 650 nm laser. Even though both the cell lines were affected by laser irradiation, A549 cells show higher cell destruction and lower IC50 values than the normal cells. Docking studies were used to analyse the interaction site and the results showed that the Cu-BMZ molecules have higher dock score than the Co-BMZ molecules. The obtained results indicate that Cu-BMZ samples have lesser particle size, higher nonlinear absorption and higher interaction energy than the Co-BMZ samples.

AB - The development of eco-friendly and effective insecticides is crucial for public health worldwide. Herein, we focused on the desert wormwood (Artemisia herba alba), a plant widely used in Arabian traditional medicine, as a source of green nanoinsecticides against mosquito vectors, as well as growth inhibitors to be employed against microbial pathogens. Ag nanoparticles (AgNPs) fabricated with the A. herba-alba extract were tested on Indian and Saudi Arabian strains of Anopheles, Aedes and Culex mosquitoes. The chemical profile of the A. herba-alba extract was determined by LC-DAD-MS and 1H NMR studies. Then, AgNPs were studied using UV-vis spectroscopy, XRD, FTIR spectroscopy, TEM, and EDX analyses. Artemisia herba-alba-synthesized AgNPs showed high larvicidal toxicity against mosquitoes from both Indian and Saudi Arabian strains. LC50 of AgNPs against Indian strains was 9.76 MUg/ml for An. stephensi, 10.70 MUg/ml for Ae. aegypti and 11.43 MUg/ml for Cx. quinquefasciatus, whereas against Saudi Arabian strains it was 33.58 MUg/ml for Ae. aegypti and 38.06 MUg/ml for Cx. pipiens. In adulticidal experiments, A. herba-alba extract showed LC50 ranging from 293.02 to 450 MUg/ml, while AgNP LC50 ranged from 8.22 to 27.39 MUg/ml. Further, low doses of the AgNPs inhibited the growth of selected microbial pathogens. Overall, A. herba-alba can be further considered as a source of phytochemicals, with special reference to saponins, for effective and prompt fabrication of AgNPs with relevant insecticidal and bactericidal activity against species of high public health importance.

AB - Like any skill in nursing, preparing students for the changes in technology needs to be incorporated into the curriculum. Electronic Patient Records (EPR) are an example of technological innovation in health care. This article presents a case study of how one faculty of healthcare, working collaboratively with a web designer, created and implemented a simulation activity to enable student nurses to develop their skills in using EPRs. An evaluation study was undertaken into students' perceptions of undertaking the simulation activity and using EPRs in the simulation activity. Findings showed that students were positive about the simulation activity and using the EPR app in the simulation, and felt well prepared for using EPR in practice. PMID- 29459315 TI - Magnetic resonance elastography to estimate brain stiffness: Measurement reproducibility and its estimate in pseudotumor cerebri patients. AB - This study determines the reproducibility of magnetic resonance elastography (MRE) derived brain stiffness in normal volunteers and compares it against pseudotumor patients before and after lumbar puncture (LP). MRE was performed on 10 normal volunteers for reproducibility and 14 pseudotumor patients before and after LP. During LP, opening and closing cerebrospinal fluid (CSF) pressures were recorded before and after removal of CSF and correlated to brain stiffness. Stiffness reproducibility was observed (r > 0.78; p < 0.008). Whole brain opening LP stiffness was significantly (p = 0.04) higher than normals, but no significant difference (p = 0.11) in closing LP measurements. No significant correlation was observed between opening and closing pressure and brain stiffness. PMID- 29459317 TI - A novel anammox process combined with vibration technology. AB - This study investigated a fixed bed anammox bioreactor that uses vibration techniques to treat synthetic inorganic wastewater. Continuous experiments indicated that the activity elevation period could be shorten to one third, when the nitrogen removal rate (NRR) reached 1 kg.N/m3.d with vibration. R2 achieved the maximum NRR of 3.3 kg.N/m3.d under the resonance state, which was 1.8 times higher than the control reactor. Analysis of vibration intensity suggested that anammox activity would be great improved with the increasing vibration. These results indicated that vibration played a key role in system performance. Furthermore, high-throughput sequencing showed that the reactor with the vibration had a higher proportion of anammox bacteria, which increased 7 times than the biofilm formation phase. Meanwhile, the proportion of Proteobacteria and Chloroflexi decreased by 37.1% and 7.78%, respectively. These results suggest that vibration could increase the anammox treatment performance and provide a better condition for the anammox bacteria. PMID- 29459318 TI - Improving cellulose nanofibrillation of waste wheat straw using the combined methods of prewashing, p-toluenesulfonic acid hydrolysis, disk grinding, and endoglucanase post-treatment. AB - Here we established a new approach for improving the cellulose nanofibrillation of high ash content waste wheat straw (WWS). The results were comprehensively elucidated from the ash removal, delignification, mechanical fibrillation and endoglucanase post-treatment. When water dosage was increased from 50 to 500 times of the WWS weight, the ash content gradually decreased during prewashing process, which facilitated lignin solubilization in subsequent p-toluenesulfonic acid (p-TsOH) hydrolysis. Approximately 80% of lignin in prewashed WWS could be dissolved during acid hydrolysis to result in a relatively higher crystallinity of 59.1%. Compared with the lignocellulosic nanofibrils (LCNF) directly obtained using acid hydrolysis and disk grinding, prewashing-assisted acid hydrolyzed WWS was fibrillated into LCNF with smaller height of 57.0 nm. Mild endoglucanase post treatment could further produce less entangled LCNF with thinner diameters. In short, this study presented a promising and green pathway to achieve an efficient utilization of agricultural residue wastes to cellulose nanomaterials. PMID- 29459319 TI - Effects of hydrostatic pressure and supercritical carbon dioxide on the viability of Botryococcus braunii algae cells. AB - In bio-based industries, Botryococcus braunii is identified as a potential resource for production of hydrocarbons having a wide range of applications in chemical and biopolymer industries. For a sustainable production platform, the algae cultivation should be integrated with downstream processes. Ideally the algae are not harvested, but the product is isolated while cultivation and growth is continued especially if the doubling time is slow. Consequently, hydrocarbons can be extracted while keeping the algae viable. In this study, the effects of pressure on the viability of B. braunii cells were tested hydrostatically and under supercritical CO2 conditions. Viability was determined by light microscopy, methylene blue uptake and by re-cultivation of the algae after treatments to follow the growth. It was concluded that supercritical CO2 was lethal to the algae, whereas hydrostatic pressure treatments up to 150 bar have not affected cell viability and recultivation was successful. PMID- 29459320 TI - Succession of the functional microbial communities and the metabolic functions in maize straw composting process. AB - Illumina MiSeq sequencing and phylogenetic investigation of communities by reconstruction of unobserved states (PICRUSt) were applied to study the dynamic changes and effects of microbial community structures as well as the metabolic function of bacterial community in maize straw composting process. Results showed that humic acid contents in loosely combined humus (HA1) and stably combined humus (HA2) increased after composting and Staphylococcus, Cellulosimicrobium and Ochrobactrum possibly participated in the transformation of the process. The bacterial communities differed in different stages of the composting. Firmicutes, Proteobacteria, Bacteroidetes and Actinobacteria were reported the dominant phyla throughout the process and the relative abundance of the dominant phyla varied significantly (p < 0.05) over time. Moreover, the total phosphorus (TP) had the greatest influence on the microbial community structure among C/N ratio, available phosphorus (AP) and humic substances. Metabolism, cellular processes and environmental information processing might be the primary functions of microbial community during the composting. PMID- 29459321 TI - Bioengineering an electro-mechanically functional miniature ventricular heart chamber from human pluripotent stem cells. AB - Tissue engineers and stem cell biologists have made exciting progress toward creating simplified models of human heart muscles or aligned monolayers to help bridge a longstanding gap between experimental animals and clinical trials. However, no existing human in vitro systems provide the direct measures of cardiac performance as a pump. Here, we developed a next-generation in vitro biomimetic model of pumping human heart chamber, and demonstrated its capability for pharmaceutical testing. From human pluripotent stem cell (hPSC)-derived ventricular cardiomyocytes (hvCM) embedded in collagen-based extracellular matrix hydrogel, we engineered a three-dimensional (3D) electro-mechanically coupled, fluid-ejecting miniature human ventricle-like cardiac organoid chamber (hvCOC). Structural characterization showed organized sarcomeres with myofibrillar microstructures. Transcript and RNA-seq analyses revealed upregulation of key Ca2+-handling, ion channel, and cardiac-specific proteins in hvCOC compared to lower-order 2D and 3D cultures of the same constituent cells. Clinically important, physiologically complex contractile parameters such as ejection fraction, developed pressure, and stroke work, as well as electrophysiological properties including action potential and conduction velocity were measured: hvCOC displayed key molecular and physiological characteristics of the native ventricle, and showed expected mechanical and electrophysiological responses to a range of pharmacological interventions (including positive and negative inotropes). We conclude that such "human-heart-in-a-jar" technology could facilitate the drug discovery process by providing human-specific preclinical data during early stage drug development. PMID- 29459322 TI - Biofunctionalized aligned microgels provide 3D cell guidance to mimic complex tissue matrices. AB - Natural healing is based on highly orchestrated processes, in which the extracellular matrix plays a key role. To resemble the native cell environment, we introduce an artificial extracellular matrix (aECM) with the capability to template hierarchical and anisotropic structures in situ, allowing a minimally invasive application via injection. Synthetic, magnetically responsive, rod shaped microgels are locally aligned and fixed by a biocompatible surrounding hydrogel, creating a hybrid anisotropic hydrogel (Anisogel), of which the physical, mechanical, and chemical properties can be tailored. The microgels are rendered cell-adhesive with GRGDS and incorporated either inside a cell-adhesive fibrin or bioinert poly(ethylene glycol) hydrogel to strongly interact with fibroblasts. GRGDS-modified microgels inside a fibrin-based Anisogel enhance fibroblast alignment and lead to a reduction in fibronectin production, indicating successful replacement of structural proteins. In addition, YAP translocation to the nucleus increases with the concentration of microgels, indicating cellular sensing of the overall anisotropic mechanical properties of the Anisogel. For bioinert surrounding PEG hydrogels, GRGDS-microgels are required to support cell proliferation and fibronectin production. In contrast to fibroblasts, primary nerve growth is not significantly affected by the biomodification of the microgels. In conclusion, this approach opens new opportunities towards advanced and complex aECMs for tissue regeneration. PMID- 29459323 TI - RF-assisted gadofullerene nanoparticles induces rapid tumor vascular disruption by down-expression of tumor vascular endothelial cadherin. AB - The tumor vasculature with unique characteristics offers an attractive target for anti-cancer therapy. Herein, we put forward a novel antitumor therapeutic mechanism based on the gadofullerene nanocrystals (GFNCs), the agent we have previously shown to efficiently disrupt tumor vasculature by size-expansion with assistance of radiofrequency (RF). However, the tumor vascular disrupting mechanism of RF-assisted GFNCs treatment was not further studied. In the present work, a rapid tumor blood flow shutdown has been observed by the vascular perfusion imaging in vivo and vascular damages were evident 6 h after the RF assisted GFNCs treatment. Importantly, a significant down-expression of tumor vascular endothelial cadherin (VE-cadherin) treated by RF-assisted GFNCs was further investigated, which caused vascular collapse, blood flow shut-down and subsequent tumor hemorrhagic necrosis. These findings set forth a systematic mechanism on the superior anti-tumor efficiency by RF-assisted GFNCs treatment. PMID- 29459324 TI - Near-infrared rechargeable "optical battery" implant for irradiation-free photodynamic therapy. AB - As a minimal or noninvasive therapeutic method for tumors, photodynamic therapy (PDT) induced by the external laser irradiations has attracted great attentions. However, the UV-visible responsive property with low tissue penetration and photothermal effect from the prolonged irradiation impedes their further applications. Herein, a near-infrared (NIR) rechargeable "optical battery" for irradiation-free PDT is fabricated by embedding upconversion materials, persistent luminescence materials, photosensitizer into biocompatible polydimethylsiloxane. After 5 s quickly charged by 980-nm NIR laser, the PDT "optical battery" can generate green persistent luminescence and produce cytotoxic singlet oxygen for continuous irradiation-free PDT (~30 min) without external irradiation. Due to deep tissue penetration and discontinuous short exposure of NIR light charging source, the "optical battery" can still be charged to continuously generate singlet oxygen in deep tissue (~4 mm) with low photothermal effect. The PDT implant can be easily optimized in size and shape aiming at different nidus sites and achieved different functions by adding other functional components (e.g. CaO2 for oxygen envolving to overcome hypoxia tumor). The effective tumor proliferation inhibiting capability of this NIR rechargeable "optical battery" may give rise to next generation of intelligent stimuli responsive nanomedicine and noninvasive photo bio-stimulation research for future clinical applications. PMID- 29459326 TI - Motor output complexity in Parkinson's disease during quiet standing and walking: Analysis of short-term correlations using the entropic half-life. AB - Parkinson's disease (PD) is associated with alterations in motor outputs such as center of pressure (CoP) adjustments during quiet standing and foot kinematics during walking. Previous research suggests that the complexity of motor outputs reflects the number of control processes stabilizing a specific movement, providing a measure that is linked to the neurological control of the movement. The Entropic Half Life (EnHL) represents a new method for assessing motor output complexity. We hypothesized that there will be a lack of neuromuscular control pathways for PD patients, resulting in a decrease in motor output complexity. We computed the EnHL of CoP adjustments during quiet standing and foot kinematics during walking of 70 PD patients and 33 age-matched controls. Patients with PD showed longer EnHL values compared to controls, suggesting a tighter motor control. Excluding vision led to a decrease of EnHL of CoP in both groups. EnHL was correlated with spatio-temporal gait parameters. We compared EnHL with the pull test and the timed up-and-go test. No significant differences were present in the pull test, yet motor output complexity was correlated with the timed up and-go test. The results suggest a reduced complexity in motor outputs of PD patients affecting distinct motor functions. PMID- 29459325 TI - Discontinuous Schedule of Bevacizumab in Colorectal Cancer Induces Accelerated Tumor Growth and Phenotypic Changes. AB - Antiangiogenics administration in colorectal cancer patients seemed promising therapeutic approach. Inspite of early encouraging results, it however gave only modest clinical benefits. When AAG was administered with discontinuous schedule, the disease showed acceleration in certain cases. Though resistance to AAG has been extensively studied, it is not documented for discontinuous schedules. To simulate clinical situations, we subjected a patient-derived CRC subcutaneous xenograft in mice to three different protocols: 1) AAG (bevacizumab) treatment for 30 days (group A) (group B was the control), 2) bevacizumab treatment for 50 days (group C) and bevacizumab for 30 days and 20 without treatment (group D), and 3) bevacizumab treatment for 70 days (group E) and 70 days treatment with a drug-break period between day 30 and 50 (group F). The tumor growth was monitored, and at sacrifice, the vascularity of tumors was measured and the proangiogenic factors quantified. Tumor phenotype was studied by quantifying cancer stem cells. Interrupting bevacizumab during treatment accelerated tumor growth and revascularization. A significant increase of proangiogenic factors was observed when therapy was stopped. On withdrawal of bevacizumab, as also after the drug-break period, the plasmatic VEGF increased significantly. Similarly, a notable increase of CSCs after the withdrawal and drug-break period of bevacizumab was observed (P<.01). The present study indicates that bevacizumab treatment needs to be maintained because discontinuous schedules tend to trigger tumor regrowth, and increase tumor resistance and CSC heterogeneity. PMID- 29459327 TI - Changes in tobacco consumption in cannabis dependent patients with schizophrenia versus non-psychiatric controls during 28-days of cannabis abstinence. AB - BACKGROUND: Tobacco and cannabis are highly co-morbid in the general population and in patients with schizophrenia. Given the putative causal mechanisms facilitating co-use, it is important to determine how cannabis cessation may influence concurrent tobacco use. Using a 28-day cannabis abstinence paradigm, we prospectively examined changes in tobacco consumption in patients with schizophrenia and controls with cannabis dependence and daily cigarette use. METHODS: Cannabis dependent patients with schizophrenia (n = 19) and controls (n = 20) completed the study with abstinence rates of 42% and 55%, respectively. Participants completed measures of substance use, withdrawal, and clinical symptoms weekly. Urine samples were collected twice weekly to biochemically verify abstinence. RESULTS: Patients reported a greater increase in cigarettes smoked per day (CPD) on Day 7 relative to baseline (2.97 cigarette increase for abstinent subgroup, p < .01) compared to controls (.06 cigarette increase for abstinent subgroup, p = .95). Initially, greater reductions in cannabis use related to greater increases in CPD relative to baseline in the patient subsample (simple slope = -2.31, p = .05), but by Day 28, CPD returned to baseline levels independent of cannabis use. CPD changes were unrelated to cannabis withdrawal. Results were similar for changes in caffeine consumption, but not for alcohol. CONCLUSIONS: Findings suggest transient tobacco substitution for cannabis in patients with schizophrenia. This provides further support for a strong association between cannabis and tobacco in schizophrenia. Future studies should focus on targeting underlying mechanisms that promote co-use to better address potential changes in concurrent substance use during treatment interventions. PMID- 29459328 TI - Risk of fentanyl-involved overdose among those with past year incarceration: Findings from a recent outbreak in 2014 and 2015. AB - Overdose is the leading cause of unintentional injury-related death. Rhode Island (RI) has the highest rate of illicit drug use nationally and the 5th highest overdose mortality rate. RI has experienced an outbreak of fentanyl-related overdoses. In incarcerated populations, risk of overdose is greatly elevated. However, little is known about fentanyl-related overdose post-release. In the current analyses, we identify changes in fentanyl-related fatal overdose among those who died in 2014 and 2015 who were incarcerated in the year before death. We linked data from the RI Office of the Medical Examiner with records from the RI Department of Corrections. We calculated risk ratios and 95% confidence intervals using log-binomial regression to compare risk of fentanyl-involved overdose death. We also compared median time to death since release, median sentence length, and median number of incarcerations in 2014 and 2015. Results indicate that the risk of dying of a fentanyl-related overdose increased (RR: 1.99 (95% CI: 1.11-3.57, p = 0.014)) from 2014 to 2015 among those with past year incarceration. This study is one of the first to describe fentanyl-related fatal overdose among those with past year incarceration. In 2015 the median sentence was longer among those with a fentanyl-related overdose death and the median time from release to death among all who had past year incarceration extended past 90 days. Access to medications for addiction treatment, overdose education, and naloxone should be available during community re-entry and extended beyond the early post-release period.

AB - The electrodeposition for alpha source preparation, using several electrolyte solution-cathode material combinations, is investigated and evaluated. The investigated factors focused on the electrodeposition time, the applied current, electrolyte volume and anode-cathode distances for the conventional electrodeposition cell (with no external stirring or cooling system). The conditions (temperature and the solution pH) during the electrodeposition process were also studied and discussed. The optimized parameters for each system are provided, and evaluated for the usage in determination of actinides (uranium, plutonium, americium and curium radioisotopes) in various samples.

AB - The 123I radionuclide (T1/2 = 13.22 h, beta+ = 100%) is one of the most potent gamma emitters for nuclear medicine. In this study, the cyclotron production of this radionuclide via different nuclear reactions namely, the 121Sb(alpha,2n), 122Te(d,n), 123Te(p,n), 124Te(p,2n), 124Xe(p,2n), 127I(p,5n) and 127I(d,6n) were investigated. The effect of the various phenomenological nuclear level density models such as Fermi gas model (FGM), Back-shifted Fermi gas model (BSFGM), Generalized superfluid model (GSM) and Enhanced generalized superfluid model (EGSM) moreover, the three microscopic level density models were evaluated for predicting of cross sections and production yield predictions. The SRIM code was used to obtain the target thickness. The 123I excitation function of reactions were calculated by using of the TALYS-1.8, EMPIRE-3.2 nuclear codes and with data which taken from TENDL-2015 database, and finally the theoretical calculations were compared with reported experimental measurements in which taken from EXFOR database. PMID- 29459331 TI - Sensitive, selective, disposable electrochemical dopamine sensor based on PEDOT modified laser scribed graphene. AB - The fabrication of a novel, and highly selective electrochemical sensor based on a poly(3,4-ethylenedioxythiophene) (PEDOT) modified laser scribed graphene (LSG), and detection of dopamine (DA) in the presence of ascorbic acid (AA) and uric acid (UA) is described. LSG electrodes were produced with a 3-dimensional macro porous network and large electrochemically-active surface area via direct laser writing on polyimide sheets. PEDOT was electrodeposited on the LSG electrode, and the physical properties of the obtained films were characterized by scanning electron microscopy (SEM) and energy dispersive X-ray diffraction microanalysis (EDAX). The modified electrodes were applied for the determination of DA in the presence of AA and UA using cyclic voltammetry (CV), and differential pulse voltammetry (DPV) techniques. The linear range for dopamine detection was found to be 1-150 uM with a sensitivity of 0.220 +/- 0.011 uA MUM-1 and a detection limit of 0.33 uM; superior values to those obtained without PEDOT. For the first time, PEDOT-modified LSG have been fabricated and assessed for high-performance dopamine sensing using cost-effective, disposable electrodes, with potential for development in further sensing applications. PMID- 29459332 TI - Distribution and ecological risk assessment of organic and inorganic pollutants in the sediments of the transnational Begej canal (Serbia-Romania). AB - This research is designed to determine the level and types of pollution in the highly contaminated sediments of the international Begej canal in Timis district, Romania and north-eastern Serbia. The cross-border canal stretch investigated is currently not navigable, but represents an important waterway between the Danube River in Serbia and the city of Timisoara. Surface sediments were monitored annually from 2008 to 2016 at 36 representative sampling locations, with a wide range of analyses, including eight heavy metals of long-term monitoring concern (Ni, Zn, Cd, Cr, Cu, Pb, As and Hg) and the 16 USEPA PAHs. The purpose of this study was to determine the diversity and impact of anthropogenic and natural sources of pollution at the pollution hot spots on the canal: at the Itebej lock (near the border with Romania) and downstream at the Klek lock. Sediment quality and ecological risk were assessed in order to determine pollutants of concern. Several multi-proxies were applied (e.g. geo-accumulation index (Igeo), ecological risk index (RI) and total benzo[a]pyrene equivalent (B[a]Peq)). To determine and predict trends, multivariate statistical methods (factor analysis of principal component analysis (PCA/FA)) were carried out on the organic and inorganic parameters analysed. In the near-border region, acute and significant ecological impacts were observed. The heavy metals Hg, Cr, Pb, Cu and Zn, and the carcinogenic PAH dibenzo[a,h]anthracene, were historically the most frequently detected harmful substances to biota in this and the wider Pannonia region. This is the first long-term study to quantify and derivate the most frequently detected harmful substances of concern for this and similar sites in the wider region, and is additionally supported by significant national and similar environmental data from previous studies in the region. PMID- 29459333 TI - Contamination status by persistent organic pollutants of the Atlantic spotted dolphin (Stenella frontalis) at the metapopulation level. AB - The Atlantic spotted dolphin (Stenella frontalis) is an endemic species of the tropical-temperate Atlantic Ocean with widespread distribution. Although this species has been the subject of a large number of studies throughout its range, it remains in the "data deficient" category of the International Union for Conservation of Nature (IUCN). Chemical pollution by persistent organic pollutants (POPs) has been listed as one of the major threats to this species, however, there is no information on a wide scale. Thus, the aim of the present study was to investigate the contamination status of spotted dolphins on the metapopulation level as well as determine spatial and temporal variations in POP concentrations and bio-accumulation. A total of 115 blubber samples collected from a large part of the Atlantic basin were analysed for PCBs, DDTs, PBDEs, chlordanes, HCB and mirex. Although PCBs and DDTs were the predominant compounds in all areas, inter-location differences in POP concentrations were observed. Dolphins found at Sao Paulo, southeastern coast of Brazil, had the highest PCB concentrations (median: 10.5 MUg/g lw) and Canary Islands dolphins had the highest DDT concentrations (median: 5.13 MUg/g lw). Differences in PCB patterns among locations were also observed. Dolphins from the Azores and Sao Paulo demonstrated a similar pattern, with relatively highly contributions of tetra- (6.8 and 5.2%, respectively) and penta-CBs (25.6 and 23.8%, respectively) and lower contributions of hepta-CBs (20.8 and 23.5%, respectively) in comparison to other areas. Moreover, the sex of the animals and the year in which sampling or capture occurred exerted an important influence on the majority of the POPs analysed. Comparisons with toxicity thresholds available in the literature reveal that the Sao Paulo and Canary Island dolphins are the most vulnerable populations and should be considered in future conservation and management programs for the Atlantic spotted dolphin. PMID- 29459334 TI - Improved rice residue burning emissions estimates: Accounting for practice specific emission factors in air pollution assessments of Vietnam. AB - In Southeast Asia and Vietnam, rice residues are routinely burned after the harvest to prepare fields for the next season. Specific to Vietnam, the two prevalent burning practices include: a). piling the residues after hand harvesting; b). burning the residues without piling, after machine harvesting. In this study, we synthesized field and laboratory studies from the literature on rice residue burning emission factors for PM2.5. We found significant differences in the resulting burning-practice specific emission factors, with 16.9 g kg-2(+/ 6.9) for pile burning and 8.8 g kg-2(+/-3.5) for non-pile burning. We calculated burning-practice specific emissions based on rice area data, region-specific fuel loading factors, combined emission factors, and estimates of burning from the literature. Our results for year 2015 estimate 180 Gg of PM2.5 result from the pile burning method and 130 Gg result from non-pile burning method, with the most likely current emission scenario of 150 Gg PM2.5 emissions for Vietnam. For comparison purposes, we calculated emissions using generalized agricultural emission factors employed in global biomass burning studies. These results estimate 80 Gg PM2.5, which is only 44% of the pile burning-based estimates, suggesting underestimation in previous studies. We compare our emissions to an existing all-combustion sources inventory, results show emissions account for 14 18% of Vietnam's total PM2.5 depending on burning practice. Within the highly urbanized and cloud-covered Hanoi Capital region (HCR), we use rice area from Sentinel-1A to derive spatially-explicit emissions and indirectly estimate residue burning dates. Results from HYSPLIT back-trajectory analysis stratified by season show autumn has most emission trajectories originating in the North, while spring has most originating in the South, suggesting the latter may have bigger impact on air quality. From these results, we highlight locations where emission mitigation efforts could be focused and suggest measures for pollutant mitigation. Our study demonstrates the need to account for emissions variation due to different burning practices. PMID- 29459335 TI - Evidence of niche partitioning among bacteria living on plastics, organic particles and surrounding seawaters. AB - Plastic pollution is widespread in ocean ecosystems worldwide, but it is unknown if plastic offers a unique habitat for bacteria compared to communities in the water column and attached to naturally-occurring organic particles. The large set of samples taken during the Tara-Mediterranean expedition revealed for the first time a clear niche partitioning between free-living (FL), organic particle attached (PA) and the recently introduced plastic marine debris (PMD). Bacterial counts in PMD presented higher cell enrichment factors than generally observed for PA fraction, when compared to FL bacteria in the surrounding waters. Taxonomic diversity was also higher in the PMD communities, where higher evenness indicated a favorable environment for a very large number of species. Cyanobacteria were particularly overrepresented in PMD, together with essential functions for biofilm formation and maturation. The community distinction between the three habitats was consistent across the large-scale sampling in the Western Mediterranean basin. 'Plastic specific bacteria' recovered only on the PMD represented half of the OTUs, thus forming a distinct habitat that should be further considered for understanding microbial biodiversity in changing marine ecosystems. PMID- 29459336 TI - Building a collective memory: the case for collective forgetting. AB - The shared reality of a community rests in part on the collective memories held by members of that community. Surprisingly, psychologists have only recently begun to study collective memories, an area of interest in the social sciences for several decades. The present paper adopts the perspective that remembering is often an act of communication. One consequence of communicative acts of remembering is that speaker and listeners can come to share the same memories, thereby providing a foundation on which to build a collective memory. Another consequence is that the selectivity of communicative acts of remembering can induce collective selective forgetting, clearly one component of any collective memory. The phenomenon of retrieval-induced forgetting is discussed in the context of dyadic conversational exchanges of unrelated individuals and conversational exchanges between ingroup and outgroup members. In addition, the paper reviews work demonstrating that what occurs at the dyadic level can shape global outcomes of complex social networks, including convergence of memories across a network. The bottom-up approach described in this paper can help us understand how individual memories can come to be shared across a community.

AB - Composting of cattle manure was conducted under four ventilation strategies, i.e., no-aeration (A-00), continuous aeration (B-44), non-aeration for 14 d and then aeration for 42 d (C-04), aeration for 14 d and then no-aeration for 42 d (D 40). Physicochemical parameters and potential ammonia oxidation (PAO) indicated that continuous and intermittent ventilation provide favourable conditions for ammonia-oxidizing bacteria (AOB) and archaea (AOA) to oxidize ammonia. Quantitative PCR (qPCR) analysis showed AOB amoA gene abundance of all treatments on every sampling day ranged from 2.25 * 105 to 2.76 * 109copies/g, was significantly lower than that of archaeal amoA gene from 2.71 * 108 to 9.05 * 1011copies/g. There was also a significantly positive relationship between PAO rates and AOB (r2 >= 0.066, p < 0.05) and AOA (r2 >= 0.300, p < 0.05) abundance. These data suggested that ammonia oxidation is driven by both AOA and AOB in cattle manure composting.

AB - The processing of oranges is a major industry worldwide and leads to the production of large amounts of orange peel waste (OPW). Energy production through anaerobic digestion of OPW is a promising option; however, the high content of essential oil, mainly composed of d-limonene, a well-known antioxidant, can cause the inhibition of the biological activity. In this paper, different pretreatment methods were tested (e.g. ensiling, aeration, thermal and alkaline treatments) to optimize the anaerobic digestion of OPW focusing on d-limonene removal. The raw and pretreated substrates were characterized and their biochemical methane production was measured. The results demonstrated the ability of some of the treatments to reduce d-limonene content up to 80%. A relatively high biomethane potential production of OPW (up to about 500 NmL CH4 g-1VS) was measured. The importance of the acclimation of inoculum and the risk connected to the accumulation of inhibiting substances in the reactor is discussed.

AB - Eco-certification is one solution to the common problem of verification of delivery of services in payment for ecosystem services (PES) schemes. Certification incurs costs, which may limit uptake, so it should be able to benefit users of certified services for it succeeds. In part to inform a project targeting expansion of the Forest Stewardship Council's forest management certification to include ecosystem services, we tested market demand for a potential certification scheme for watershed services. Using choice experiments among end-users of water subject to an existing PES scheme in Lombok, Indonesia, we assessed potential business values of certification. Our results suggested that preferred business values included credible information disclosure on improved water quality, reduced flood risk, environmental safeguards, and/or social safeguards of the upstream forests. These preferences indicate potential demand for a certification of forest watershed services designed to provide such information to end users.

AB - Wet air oxidation (WAO) is a candidate technique for the effective treatment of spent caustic wastewater. In this work, cresols were chosen as model compounds to represent cresylic spent caustic wash. Graphene oxide (GO) is a promising catalyst as well as support for the wet oxidation process, due to its unique structure and properties. For the first time, GO and ruthenium supported on graphene oxide (Ru/GO) were employed for WAO of cresylic isomers. The aforesaid materials were synthesized by modified Hummer's method and characterized using scanning electron microscopy (SEM), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), Fourier transform infrared (FT IR) spectroscopy, X-ray diffraction (XRD) and Brunauer-Emmett-Teller (BET) analysis. The performance of the investigated materials for WAO of cresols was studied in a slurry reactor. The best reaction conditions for GO were 175 degrees C and 0.69 MPa O2 pressure. Total organic carbon (TOC) degradation achieved at these conditions was 54.9, 48.9 and 61.2% for o-cresol, m-cresol and p-cresol, respectively. The amount of TOC degradation obtained by using Ru/GO at the same reaction conditions was 66.4, 53.4 and 73.9% for o-cresol, m-cresol and p-cresol, respectively. It was found that the order of reactivity for cresols was p-cresol > o-cresol > m-cresol. Finally, kinetics of TOC destruction during CWAO of p-cresol over GO was described using a two-step power law model.

AB - PURPOSE: We aimed to evaluate the association between transfusion practices and clinical outcomes in patients with traumatic brain injury. MATERIAL AND METHODS: We conducted a retrospective cohort study of adult patients with moderate or severe traumatic brain injury admitted to the intensive care unit (ICU) of a level I trauma center between 2009 and 2013. The associations between hemoglobin (Hb) level, red blood cell (RBC) transfusion and clinical outcomes were estimated using robust Poisson models and proportional hazard models with time-dependent variables, adjusted for confounders. RESULTS: We included 215 patients. Sixty-six patients (30.7%) were transfused during ICU stay. The median pre-transfusion Hb among transfused patients was 81g/L (IQR 67-100), while median nadir Hb among non transfused patients was 110g/L (IQR 93-123). Poor outcomes were significantly more frequent in patients who were transfused (mortality risk ratio [RR]: 2.15 [95% CI 1.37-3.38] and hazard ratio: 3.06 [95% CI 1.57-5.97]; neurological complications RR: 3.40 [95% CI 1.35-8.56]; trauma complications RR: 1.65 [95% CI 1.31-2.08]; ICU length of stay geometric mean ratio: 1.42 [95% CI 1.06-1.92]). CONCLUSIONS: During ICU stay, transfused patients tended to have lower Hb levels and worse outcomes than patients who did not receive RBCs, after adjustment for confounders. PMID- 29459343 TI - A quasi-optical and corrugated waveguide microwave transmission system for simultaneous dynamic nuclear polarization NMR on two separate 14.1 T spectrometers. AB - Nuclear magnetic resonance (NMR) is an intrinsically insensitive technique, with Boltzmann distributions of nuclear spin states on the order of parts per million in conventional magnetic fields. To overcome this limitation, dynamic nuclear polarization (DNP) can be used to gain up to three orders of magnitude in signal enhancement, which can decrease experimental time by up to six orders of magnitude. In DNP experiments, nuclear spin polarization is enhanced by transferring the relatively larger electron polarization to NMR active nuclei via microwave irradiation. Here, we describe the design and performance of a quasi optical system enabling the use of a single 395 GHz gyrotron microwave source to simultaneously perform DNP experiments on two different 14.1 T (1H 600 MHz) NMR spectrometers: one configured for magic angle spinning (MAS) solid state NMR; the other configured for solution state NMR experiments. In particular, we describe how the high power microwave beam is split, transmitted, and manipulated between the two spectrometers. A 13C enhancement of 128 is achieved via the cross effect for alanine, using the nitroxide biradical AMUPol, under MAS-DNP conditions at 110 K, while a 31P enhancement of 160 is achieved via the Overhauser effect for triphenylphosphine using the monoradical BDPA under solution NMR conditions at room temperature. The latter result is the first demonstration of Overhauser DNP in the solution state at a field of 14.1 T (1H 600 MHz). Moreover these results have been produced with large sample volumes (~100 uL, i.e. 3 mm diameter NMR tubes). PMID- 29459344 TI - Low level of serum HDL-cholesterol with increased sIL-2R predicts a poor clinical outcome for patients with malignant lymphoma and adult T-cell leukemia-lymphoma. AB - Low concentrations of high-density lipoprotein cholesterol (HDL-C) have been reported in patients with hematological malignancies. However, the proof of decreased HDL-C in hematological malignancies and its association with clinical outcomes remain unclear. We analyzed 140 Japanese patients with malignant lymphoma (ML) and adult T-cell leukemia-lymphoma (ATLL). HDL-C, LDL-C and soluble interleukin-2 receptor (sIL-2R) were measured. Treatment decisions were determined with established protocols. HDL-C was 0.98 +/- 0.45 mmol/l in patients and 1.51 +/- 0.35 mmol/l in controls (P < 0.001). LDL-C was lower in patients than in controls (2.76 +/- 0.96, 3.16 +/- 0.76 mmol/l, respectively, P < 0.001). HDL-C was the lowest in ATLL (0.81 +/- 0.37 mmol/l), modest in non-Hodgkin lymphoma (1.09 +/- 0.42 mmol/l) and the highest in Hodgkin's disease (1.14 +/- 0.68 mmol/l), (P = 0.0019). Inverse correlation was found between HDL-C and sIL 2R (r = -0.6584, P < 0.001). Categorized patients into 3 subgroups according to HDL-C (<0.52, 0.52-1.02 and >=1.03 mmol/l), sIL-2R were the highest (median, 36,675; IQR, 17,180-92,600 U/mL) in patients with HDL-C < 0.52 mmol/l, modest (2386, 1324-8340) in HDL-C 0.52-1.02 mmol/l and the lowest (761, 450-1596) in HDL C >= 1.03 mmol/l (P < 0.001). In Cox regression model, the lowest HDL-C levels, <0.52 mmol/l, were associated with poorer clinical outcome and the hazard ratio was 5.73 (95%CI, 3.09-10.50; P < 0.001). In Kaplan-Meier analysis according to HDL-C tertiles (<0.78, 0.78-1.10 and >=1.11 mmol/l), patients with lowest HDL-C tertile showed inferior overall survival with a median follow-up of 23 months (P < 0.001). We concluded that cytokine-induced low levels of HDL-C in patients with ML and ATLL has independent prognostic significance, and suggesting an early indicator of poorer outcome. PMID- 29459346 TI - Predictors of retinal atrophy in multiple sclerosis: A longitudinal study using spectral domain optical coherence tomography with segmentation analysis. AB - BACKGROUND: Multiple sclerosis is an inflammatory demyelinating disease characterized by progressive axonal loss affecting mainly the inner retinal layers. Optical coherence tomography (OCT) provides in-vivo quantification of the retinal layers and allows measuring progressive retinal changes. Our objective was to assess the longitudinal changes in the retina using spectral domain OCT (SDOCT) and to identify independent predictors affecting retinal thinning in MS patients. METHODS: A prospective study in a tertiary care MS center was conducted to study the longitudinal retinal changes in MS patients. All subjects underwent baseline and follow up OCT assessment with segmentation analysis. Regression analysis was performed to assess clinical factors (age, sex, disease duration, history of optic neuritis before baseline, non-ocular clinical relapses) and MRI disease activity during the follow-up period. RESULTS: The study included 102 MS patients with a mean follow-up duration of 3.9 +/- SD years. At the last follow up assessments, there were significant thinning of the average macular thickness (AMT) (p < .001), macular nerve fiber layer (MRNFL) (p < .001), ganglion cell inner plexiform layer (GCIPL) (p < .001), and the peripapillary nerve fiber layer (PRNFL) (p < .001), compared to baseline. Early disease duration up to 10 years was associated with thinning of AMT, PRNFL, and GCIPL, while longer disease duration (> 15 years) was associated with only GCIPL thinning. Prior optic neuritis was predictive of more thinning of PRNFL (p = < .01), while MRI activity and female gender were significantly associated with more MRNFL thinning (p = < .01). CONCLUSION: MS is associated with longitudinal thinning affecting AMT inner retinal layers (MRNFL, GCIPL, PRNFL). Early disease duration, female gender, MRI activity, and prior optic neuritis were predictive of faster rate of neuro-axonal loss. This may have implications in the design of future therapeutic trials. PMID- 29459345 TI - Melanoma exosomes promote mixed M1 and M2 macrophage polarization. AB - Macrophages are key participants in melanoma growth and survival. In general, macrophages can be classified as M1 or M2 activation phenotypes. Increasing evidence demonstrates that melanoma exosomes also facilitate tumor survival and metastasis. However, the role of melanoma exosomes in directly influencing macrophage function is poorly understood. Herein, we investigated the hypothesis that natural melanoma exosomes might directly influence macrophage polarization. To explore this hypothesis, ELISA, RT-qPCR, and macrophage functional studies were performed in vitro using an established source of melanoma exosomes (B16 F10). ELISA results for melanoma exosome induction of common M1 and M2 cytokines in RAW 264.7 macrophages, revealed that melanoma exosomes do not polarize macrophages exclusively in the M1 or M2 direction. Melanoma exosomes induced the M1 and M2 representative cytokines TNF-alpha and IL-10 respectively. Further assessment, using an RT-qPCR array with RAW 264.7 and primary macrophages, confirmed and extended the ELISA findings. Upregulation of markers common to both M1 and M2 polarization phenotypes included CCL22, IL-12B, IL-1beta, IL-6, i-NOS, and TNF-alpha. The M2 cytokine TGF-beta was upregulated in primary but not RAW 264.7 macrophages. Pro-tumor functions have been attributed to each of these markers. Macrophage functional assays demonstrated a trend toward increased i-NOS (M1) to arginase (M2) activity. Collectively, the results provide the first evidence that melanoma exosomes can induce a mixed M1 and M2 pro-tumor macrophage activation phenotype.

AB - OBJECTIVES: To determine the individual and combined influences of smoking and alcohol consumption on lipid profile in male adults in northwest rural China. DESIGN: Cross-sectional study. METHODS: In total, 4614 subjects were enrolled in the cross-sectional study, performed between 2008 and 2012. The present study examined males aged >=18 years from northwest rural China (n = 707). Data on current smoking and drinking status were collected. Logistic regression was used to estimate the individual and combined influences of smoking and alcohol consumption on lipid profile. Age, ethnic group, educational background, smoking (or alcohol consumption), waist circumference, body mass index, blood pressure and fasting blood glucose were adjusted as confounders. RESULTS: Total cholesterol (TC)/high-density lipoprotein cholesterol (HDL-C) ratio, triglycerides (TG)/HDL-C ratio, low-density lipoprotein cholesterol (LDL-C)/HDL-C ratio and visceral adiposity index (VAI) were significantly higher in smokers than in non-smokers, whereas HDL-C was lower in smokers. TG/HDL-C ratio, LDL C/HDL-C ratio, TG, lipid accumulation product and VAI were significantly higher in drinkers than non-drinkers. After adjustment for confounders, significant relationships were observed between smoking status and any dyslipidemia, low HDL C and high VAI (odds ratios [ORs]: 2.53 [95% confidence interval {CI}: 1.25 5.15], 6.13 [95% CI: 2.84-13.25] and 4.39 [95% CI: 2.02-9.54], respectively). The OR for any dyslipidaemia was 1.94 (95% CI: 1.09-3.48) for subjects who smoke and drank alcohol compared with subjects who did not smoke or drink alcohol. CONCLUSIONS: Abnormalities in lipid profile are correlated with smoking and alcohol consumption, which calls for intervention strategies to prevent dyslipidaemia and control risk factors for cardiovascular disease. PMID- 29459349 TI - Spatial distribution of bisphenol S in surface water and human serum from Yangtze River watershed, China: Implications for exposure through drinking water. AB - Bisphenol S (BPS) is an emerging environmental contaminant. The occurrence of this compound in humans and the environment is not well described. In this study, 120 surface water samples and 240 human serum samples were collected along the Yangtze River in 2015 for the determination of the occurrence of BPS. Surface water and human serum samples were extracted by solid phase extraction and liquid liquid extraction, respectively, and analyzed by ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). BPS was detected in all river water samples at concentrations that ranged from 0.18 to 14.9 ng/L (median: 0.98 ng/L), with higher concentrations in spring than summer. The median estimated daily intake (EDI) of BPS through water ingestion by infants in spring and summer was 0.12 and 0.06 ng/kg body weight (bw)/day, respectively. BPS was detected in human serum with the highest concentrations in samples from Nanjing (median: 0.65 ng/mL, maximum: 169 ng/mL) among the four cities studied. No significant gender related difference in BPS concentrations was observed in human sera, while higher concentrations were found in younger individuals than elderly. The EDI of BPS calculated based on serum concentrations of adults in Nanjing was 22.8 ng/kg bw/day. Ingestion of water accounted for <1% of the total BPS intake by the Chinese population. This is the first report of the occurrence of BPS in water from the Yangtze River and human serum from several cities located along this river in China. PMID- 29459350 TI - PBDEs and Dechlorane Plus in the environment of Guiyu, Southeast China: A historical location for E-waste recycling (2004, 2014). AB - Polybrominated diphenyl ethers (PBDEs, tri-to hepta-BDEs) and Dechlorane Plus (DP) in multiple samples (soil, sediment, road dust, and PM2.5 particles) in historical locations of our previous work in Guiyu (electronic-waste recycling town) in southeastern China were investigated in 2014. Ten years later, PBDEs and DP were detected in 100% of the samples. ?3-7PBDEs were still relatively great, ranging from 1.2 * 101 to 2.1 * 103 ng/g dry weight (dw) in soil, 2.1 to 3.2 * 103 ng/g dw in sediment, 1.0 * 101 to 1.1 * 104 ng/g dw in road dust, which were a little less than or close to those measured in 2004. However, ?3-7PBDEs in PM2.5 (5.0 * 102 to 8.4 * 102 pg/m3) were significantly lower in 2014. BDE-47, 99, -153, and -183 were predominant congeners, which were also predominant PBDEs reported in Guiyu (2006-2008). Greater proportions of lesser-brominated BDEs were predominant in PM2.5 than other samples. DP was detected in 100% of the samples collected with high levels. Total syn-DP and anti-DP concentrations were 3.8 to 2.1 * 103 ng/g dw in soil, 1.1 * 103 to 7.2 * 103 ng/g dw in sediment, 1.4 * 101 to 1.1 * 103 ng/g dw in road dust, and 1.8 * 102 and 1.7 * 102 pg/m3 in PM2.5. Most of the fractions of anti-DP (fanti) (70%-80%) were consistent among samples. The health risk assessment showed that hazard indexes (HIs) of PBDEs or DPs for child or adult were all lower than 0.16. PMID- 29459351 TI - Hexabromocyclododecane in polystyrene packaging: A downside of recycling? AB - While there are no regulatory fire safety obligations for polystyrene (PS) when used as packaging material, concerns exist that such packaging material may contain the flame retardant hexabromocyclododecane (HBCDD) as a result of uncontrolled recycling activities. To evaluate these concerns, we collected 50 samples of PS packaging materials from the UK and 20 from Ireland. HBCDD was detected in 63 (90%) of samples, with concentrations in 4 samples from Ireland exceeding the EU's low POP concentration limit (LPCL) of 0.1% above which articles may not be recycled. Moreover, 2 further samples contained HBCDD >0.01%. While our samples were obtained in the 12 month period prior to the March 2016 introduction of the EU's 0.01% concentration limit above which articles may not be placed on the market, our data suggest that continued monitoring is required to assess compliance with this limit value. Ratios of alpha vs. gamma-HBCDD in our EPS packaging samples (average = 0.63) exceeded significantly (p = 0.025) those in EPS building insulation material samples (average = 0.24) reported previously for Ireland. This shift towards alpha-HBCDD in packaging EPS is consistent with the additional thermal processing experienced by recycled PS and suggests the source of HBCDD in PS packaging is recycled PS insulation foam. This is of concern owing to the higher bioavailability and lower metabolic clearance of alpha-HBCDD compared to the beta- and gamma-isomers. PMID- 29459352 TI - Influence of calcium and phosphate on pH dependency of arsenite and arsenate adsorption to goethite. AB - In the environment, simultaneous presence of arsenic (As) of different oxidation states is common, which hampers our understanding of As behavior. In the current study, the pH dependency of arsenite (As(III)) and arsenate (As(V)) adsorption to goethite under the influence of calcium (Ca2+) (as a major cation) and phosphate (PO43-) (as a major anion) was studied, and the reliability of the CD-MUSIC model prediction was tested. The results show that the presence of the major ions led in general to a weaker and more complicated pH dependency of As adsorption. Calcium promoted As(V) adsorption especially at high pH, which can reverse the direction of the pH dependency. The presence of Ca2+ can even decrease As(III) adsorption when As(V) and/or PO43- are present. Phosphate competed strongly with both As(III) and As(V) in their adsorption, especially at intermediate and low pH. In the multi-component system, As(III) adsorbs weaker than As(V) over the environmental relevant pH range, therefore it is often the dominant As species in solution and soluble As(III) concentration generally decreases with increasing pH. In the same pH range, As(V) adsorption shows a complicated pH dependency. Soluble As(V) reaches a minimum around pH 6 at high concentration of major bivalent cations (e.g. Ca2+), whereas soluble As(V) will decrease with pH at low bivalent cation concentrations. The experimental results can be reliably predicted and explained with the CD-MUSIC model. The outcome of this study can provide understanding needed in the risk assessment and remediation of As contaminated soils and water. PMID- 29459353 TI - DNA damage in a liver tissue of metal exposed Clethrionomys glareolus. AB - It is widely known that some toxic agents may act on DNA strand resulting in its damages. One of the possible impairments is formation of abasic sites in DNA. The aim of this study was to indicate a presence of these DNA sites in the liver tissue of bank voles inhabiting the vicinity of zinc/lead smelters. Samples that were used originated from animals collected from unpolluted (Niepolomice, Telesnica Oszwarowa, Mikolajki) and polluted (Miasteczko Slaskie, Katowice, Olkusz) populations. They significantly differed in terms of tissue lead concentrations in the kidney and liver. The means of detected AP sites per 105 bp ranged between 3.39 (Telesnica Oszwarowa) to 5.13 (Miasteczko Slaskie). Statistical analysis (ANOVA) showed no difference in terms of number of the AP sites between single populations. However, t-test showed significant difference between the unpolluted and polluted populations. Factorial ANOVA indicated that sex is not a factor influencing the number of AP sites. The analyses revealed statistically significant relationships between the number of AP sites and Cu concentrations in the liver, and also Pb and Cd concentrations in the kidney. PMID- 29459354 TI - Mercury and metallothioneins in blood fractions and tissues of captive Morelet's crocodiles in Quintana Roo, Mexico. AB - Even though studies of heavy metals and their relation with metallothioneins (MTs) in reptile tissues have been conducted, research on heavy metals and MTs in organs and blood fractions of crocodylians is limited. To date there are no studies on the distribution of MTs in organs and their relation with mercury (Hg), or the concentration of MTs in plasma and erythrocytes of crocodylians. In order to understand the role of MTs in crocodiles, our aim was to assess the detoxification mechanisms for exposure to metals in Morelet's crocodile (Crocodylus moreletii) by using two biomarkers (Hg and MTs) in blood fractions and tissues, and comparing them with concentrations between two populations of crocodiles, one previously wild and currently captive (Theme Park) and another raised in a Wildlife Management Unit (WMU). The caudal scutes from the Theme Park showed higher concentrations of Hg than those from the skin in the WMU samples, and significant negative relationships were observed between the total length (TL) and Hg in the scutes. The significant negative relationship between Hg and hemoglobin (Hb) may be due to disorders in the oxidation process and even denature of this protein, while the positive trend observed between MTs and Hb is consistent with the detoxifying functions and the protection against oxidative damage. This study is the first to report Hg in the erythrocytes of crocodylians and the use of MTs for testing the potential of these biomarkers as a tool to assess Hg exposure in crocodile's habitats. PMID- 29459355 TI - Mobile Phone Ownership Is Not a Serious Barrier to Participation in Studies: Descriptive Study. AB - BACKGROUND: Rather than providing participants with study-specific data collection devices, their personal mobile phones are increasingly being used as a means for collecting geolocation and ecological momentary assessment (EMA) data in public health research. OBJECTIVE: The purpose of this study was to (1) describe the sociodemographic characteristics of respondents to an online survey screener assessing eligibility to participate in a mixed methods study collecting geolocation and EMA data via the participants' personal mobile phones, and (2) examine how eligibility criteria requiring mobile phone ownership and an unlimited text messaging plan affected participant inclusion. METHODS: Adult (>=18 years) daily smokers were recruited via public advertisements, free weekly newspapers, printed flyers, and word of mouth. An online survey screener was used as the initial method of determining eligibility for study participation. The survey screened for twenty-eight inclusion criteria grouped into three categories, which included (1) cell phone use, (2) tobacco use, and (3) additional criteria. RESULTS: A total of 1003 individuals completed the online screener. Respondents were predominantly African American (605/1003, 60.3%) (60.4%), male (514/1003, 51.3%), and had a median age of 35 years (IQR 26-50). Nearly 50% (496/1003, 49.5%) were unemployed. Most smoked menthol cigarettes (699/1003, 69.7%), and had a median smoking history of 11 years (IQR 5-21). The majority owned a mobile phone (739/1003, 73.7%), could install apps (86.8%), used their mobile phone daily (89.5%), and had an unlimited text messaging plan (871/1003, 86.8%). Of those who completed the online screener, 302 were eligible to participate in the study; 163 were eligible after rescreening, and 117 were enrolled in the study. Compared to employed individuals, a significantly greater proportion of those who were unemployed were ineligible for the study based on mobile phone inclusion criteria (P<.001); yet, 46.4% (333/717) of the individuals who were unemployed met all mobile phone inclusion criteria. CONCLUSIONS: Inclusion criteria requiring participants to use their personal mobile phones for data collection was not a major barrier to study participation for most respondents who completed the online screener, including those who were unemployed.

PMID- 29459356 TI - Three-Factor Structure of the eHealth Literacy Scale Among Magnetic Resonance Imaging and Computed Tomography Outpatients: A Confirmatory Factor Analysis. AB - BACKGROUND: Electronic health (eHealth) literacy is needed to effectively engage with Web-based health resources. The 8-item eHealth literacy scale (eHEALS) is a commonly used self-report measure of eHealth literacy. Accumulated evidence has suggested that the eHEALS is unidimensional. However, a recent study by Sudbury Riley and colleagues suggested that a theoretically-informed three-factor model fit better than a one-factor model. The 3 factors identified were awareness (2 items), skills (3 items), and evaluate (3 items). It is important to determine whether these findings can be replicated in other populations. OBJECTIVE: The aim of this cross-sectional study was to verify the three-factor eHEALS structure among magnetic resonance imaging (MRI) and computed tomography (CT) medical imaging outpatients. METHODS: MRI and CT outpatients were recruited consecutively in the waiting room of one major public hospital. Participants self-completed a touchscreen computer survey, assessing their sociodemographic, scan, and internet use characteristics. The eHEALS was administered to internet users, and the three factor structure was tested using structural equation modeling. RESULTS: Of 405 invited patients, 87.4% (354/405) were interested in participating in the study, and of these, 75.7% (268/354) were eligible. Of the eligible participants, 95.5% (256/268) completed all eHEALS items. Factor loadings were 0.80 to 0.94 and statistically significant (P<.001). All reliability measures were acceptable (indicator reliability: awareness=.71-.89, skills=.78-.80, evaluate=.64-.79; composite reliability: awareness=.89, skills=.92, evaluate=.89; variance extracted estimates: awareness=.80, skills=.79, evaluate=.72). Two out of three goodness-of-fit indices were adequate (standardized root mean square residual (SRMR)=.038; comparative fit index (CFI)=.944; root mean square error of approximation (RMSEA)=.156). Item 3 was removed because of its significant correlation with item 2 (Lagrange multiplier [LM] estimate 104.02; P<.001) and high loading on 2 factors (LM estimate 91.11; P<.001). All 3 indices of the resulting 7-item model indicated goodness of fit (chi211=11.3; SRMR=.013; CFI=.999; RMSEA=.011). CONCLUSIONS: The three-factor eHEALS structure was supported in this sample of MRI and CT medical imaging outpatients. Although further factorial validation studies are needed, these 3 scale factors may be used to identify individuals who could benefit from interventions to improve eHealth literacy awareness, skill, and evaluation competencies.

PMID- 29459357 TI - Attitudes Toward e-Mental Health Services in a Community Sample of Adults: Online Survey. AB - BACKGROUND: Despite evidence that e-mental health services are effective, consumer preferences still appear to be in favor of face-to-face services. However, the theory of planned behavior (TPB) suggests that cognitive intentions are more proximal to behavior and thus may have a more direct influence on service use. Investigating individual characteristics that influence both preferences and intentions to use e-mental health services is important for better understanding factors that might impede or facilitate the use of these services. OBJECTIVE: This study explores predictors of preferences and intentions to access e-mental health services relative to face-to-face services. Five domains were investigated (demographics, technology factors, personality, psychopathology, and beliefs), identified from previous studies and informed by the Internet interventions model. We expected that more participants would report intentions to use e-mental health services relative to reported preferences for this type of support and that these 5 domains would be significantly associated with both intentions and preferences toward online services. METHODS: A mixed sample of 308 community members and university students was recruited through social media and the host institution in Australia. Ages ranged between 17 and 68 years, and 82.5% (254/308) were female. Respondents completed an online survey. Chi-square analysis and t tests were used to explore group differences, and logistic regression models were employed to explore factors predicting preferences and intentions. RESULTS: Most respondents (85.7%, 264/308) preferred face-to-face services over e-mental health services. Relative to preferences, a larger proportion of respondents (39.6%, 122/308) endorsed intentions to use e mental health services if experiencing mental health difficulties in the future. In terms of the 5 predictor domains, 95% CIs of odds ratios (OR) derived from bootstrapped standard errors suggested that prior experience with online services significantly predicted intentions to use self-help (95% CI 2.08-16.24) and therapist-assisted (95% CI 1.71-11.90) online services in future. Being older predicted increased intentions to use therapist-assisted online services in future (95% CI 1.01-1.06), as did more confidence using computers and the Internet (95% CI 1.06-2.69). Technology confidence was also found to predict greater preference for online services versus face-to-face options (95% CI 1.24 4.82), whereas higher doctor-related locus of control, or LOC (95% CI 0.76-0.95), and extraversion (95% CI 0.88-1.00) were predictive of lower likelihood of preferring online services relative to face-to-face services. CONCLUSIONS: Despite generally low reported preferences toward e-mental health services, intentions to access these services are higher, raising the question of how to best encourage translation of intentions into behavior (ie, actual use of programs). Strategies designed to ease people into new Internet-based mental health programs (to enhance confidence and familiarity) may be important for increasing the likelihood that they will return to such programs later.

AB - The transcription repressor BACH1 performs mutually independent dual roles in transcription regulation and chromosome alignment during mitosis by supporting polar ejection force of mitotic spindle. We now found that the mitotic spindles became oblique relative to the adhesion surface following endogenous BACH1 depletion in HeLa cells. This spindle orientation rearrangement was rescued by re expression of BACH1 depending on its interactions with HMMR and CRM1, both of which are required for the positioning of mitotic spindle, but independently of its DNA-binding activity. A mass spectrometry analysis of BACH1 complexes in interphase and M phase revealed that BACH1 lost during mitosis interactions with proteins involved in chromatin and gene expression but retained interactions with HMMR and its known partners including CHICA. By analyzing BACH1 modification using stable isotope labeling with amino acids in cell culture, mitosis-specific phosphorylations of BACH1 were observed, and mutations of these residues abolished the activity of BACH1 to restore mitotic spindle orientation in knockdown cells and to interact with HMMR. Detailed histological analysis of Bach1-deficient mice revealed lengthening of the epithelial fold structures of the intestine. These observations suggest that BACH1 performs stabilization of mitotic spindle orientation together with HMMR and CRM1 in mitosis, and that the cell cycle-specific phosphorylation switches the transcriptional and mitotic functions of BACH1. PMID- 29459359 TI - Impact of dietary patterns and the main food groups on mortality and recurrence in cancer survivors: a systematic review of current epidemiological literature. AB - OBJECTIVE: To determine whether there is an association between dietary patterns/indices and foods from the main food groups (highest vs lowest intakes) prior to or after cancer diagnosis and mortality and cancer recurrence in cancer survivors. PARTICIPANTS: Survivors of common cancers with a 10-year survival rate of >=50%: bladder, bowel, breast, cervical, kidney, laryngeal, prostate, testicular, uterine cancer, malignant melanoma and (non-)Hodgkin's lymphoma. OUTCOME MEASURES: Mortality (overall, cancer-specific, from other causes) and cancer recurrence. INFORMATION SOURCES: PubMed, Embase and the Cochrane Library were searched from inception to April 2017. Additional studies were identified by searching reference lists. Two authors independently screened titles and abstracts, assessed study quality and extracted the data. RESULTS: A total of 38 studies were included. The risk of bias was rated low for the included randomised controlled trials (RCTs) and moderate for the cohort studies. The quality of evidence was assessed with the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach and was rated moderate (RCTs), and (very)low (cohort studies). Reducing the amount of fat after diagnosis appears to decrease the risk of breast cancer recurrence. Adherence to a high-quality diet and prudent diet after diagnosis appears to decrease the risk of death from other causes (and overall mortality for high-quality diet) in breast cancer survivors. Adherence to a Western diet, before and after diagnosis, appears to increase the risk of overall mortality and death from other causes among breast cancer survivors. Evidence from studies among other cancer survivors was too limited or could not be identified. CONCLUSION: For many cancer survivors, there is little evidence to date to indicate that particular dietary behaviours influence outcomes with regard to recurrence and mortality. Notwithstanding, limited evidence suggests that a low-fat diet, a high-quality diet and a prudent diet are beneficial for breast cancer survivors, while a Western diet is detrimental for breast cancer survivors.

PMID- 29459361 TI - Comparison of Reduced-Dose Prasugrel and Standard-Dose Clopidogrel in Elderly Patients With Acute Coronary Syndromes Undergoing Early Percutaneous Revascularization. AB - BACKGROUND: Elderly patients are at elevated risk of both ischemic and bleeding complications after an acute coronary syndrome and display higher on-clopidogrel platelet reactivity compared with younger patients. Prasugrel 5 mg provides more predictable platelet inhibition compared with clopidogrel in the elderly, suggesting the possibility of reducing ischemic events without increasing bleeding. METHODS: In a multicenter, randomized, open-label, blinded end point trial, we compared a once-daily maintenance dose of prasugrel 5 mg with the standard clopidogrel 75 mg in patients >74 years of age with acute coronary syndrome undergoing percutaneous coronary intervention. The primary end point was the composite of mortality, myocardial infarction, disabling stroke, and rehospitalization for cardiovascular causes or bleeding within 1 year. The study was designed to demonstrate superiority of prasugrel 5 mg over clopidogrel 75 mg. RESULTS: Enrollment was interrupted, according to prespecified criteria, after a planned interim analysis, when 1443 patients (40% women; mean age, 80 years) had been enrolled with a median follow-up of 12 months, because of futility for efficacy. The primary end point occurred in 121 patients (17%) with prasugrel and 121 (16.6%) with clopidogrel (hazard ratio, 1.007; 95% confidence interval, 0.78 1.30; P=0.955). Definite/probable stent thrombosis rates were 0.7% with prasugrel versus 1.9% with clopidogrel (odds ratio, 0.36; 95% confidence interval, 0.13 1.00; P=0.06). Bleeding Academic Research Consortium types 2 and greater rates were 4.1% with prasugrel versus 2.7% with clopidogrel (odds ratio, 1.52; 95% confidence interval, 0.85-3.16; P=0.18). CONCLUSIONS: The present study in elderly patients with acute coronary syndromes showed no difference in the primary end point between reduced-dose prasugrel and standard-dose clopidogrel. However, the study should be interpreted in light of the premature termination of the trial. CLINICAL TRIAL REGISTRATION: URL: https://www.clinicaltrials.gov. Unique identifier: NCT01777503. PMID- 29459363 TI - Heart Failure Stimulates Tumor Growth by Circulating Factors. AB - BACKGROUND: Heart failure (HF) survival has improved, and nowadays, many patients with HF die of noncardiac causes, including cancer. Our aim was to investigate whether a causal relationship exists between HF and the development of cancer. METHODS: HF was induced by inflicting large anterior myocardial infarction in APCmin mice, which are prone to developing precancerous intestinal tumors, and tumor growth was measured. In addition, to rule out hemodynamic impairment, a heterotopic heart transplantation model was used in which an infarcted or sham operated heart was transplanted into a recipient mouse while the native heart was left in situ. After 6 weeks, tumor number, volume, and proliferation were quantified. Candidate secreted proteins were selected because they were previously associated both with (colon) tumor growth and with myocardial production in post-myocardial infarction proteomic studies. Myocardial gene expression levels of these selected candidates were analyzed, as well as their proliferative effects on HT-29 (colon cancer) cells. We validated these candidates by measuring them in plasma of healthy subjects and patients with HF. Finally, we associated the relation between cardiac specific and inflammatory biomarkers and new-onset cancer in a large, prospective general population cohort. RESULTS: The presence of failing hearts, both native and heterotopically transplanted, resulted in significantly increased intestinal tumor load of 2.4 fold in APCmin mice (all P<0.0001). The severity of left ventricular dysfunction and fibrotic scar strongly correlated with tumor growth ( P=0.002 and P=0.016, respectively). We identified several proteins (including serpinA3 and A1, fibronectin, ceruloplasmin, and paraoxonase 1) that were elevated in human patients with chronic HF (n=101) compared with healthy subjects (n=180; P<0.001). Functionally, serpinA3 resulted in marked proliferation effects in human colon cancer (HT-29) cells, associated with Akt-S6 phosphorylation. Finally, elevated cardiac and inflammation biomarkers in apparently healthy humans (n=8319) were predictive of new-onset cancer (n=1124) independently of risk factors for cancer (age, smoking status, and body mass index). CONCLUSIONS: We demonstrate that the presence of HF is associated with enhanced tumor growth and that this is independent of hemodynamic impairment and could be caused by cardiac excreted factors. A diagnosis of HF may therefore be considered a risk factor for incident cancer. PMID- 29459364 TI - Choosing the optimum strategy for rTMS. PMID- 29459365 TI - Making soft intelligence hard: a multi-site qualitative study of challenges relating to voice about safety concerns. AB - BACKGROUND: Healthcare organisations often fail to harvest and make use of the 'soft intelligence' about safety and quality concerns held by their own personnel. We aimed to examine the role of formal channels in encouraging or inhibiting employee voice about concerns. METHODS: Qualitative study involving personnel from three academic hospitals in two countries. Interviews were conducted with 165 participants from a wide range of occupational and professional backgrounds, including senior leaders and those from the sharp end of care. Data analysis was based on the constant comparative method. RESULTS: Leaders reported that they valued employee voice; they identified formal organisational channels as a key route for the expression of concerns by employees. Formal channels and processes were designed to ensure fairness, account for all available evidence and achieve appropriate resolution. When processed through these formal systems, concerns were destined to become evidenced, formal and tractable to organisational intervention. But the way these systems operated meant that some concerns were never voiced. Participants were anxious about having to process their suspicions and concerns into hard evidentiary facts, and they feared being drawn into official procedures designed to allocate consequence. Anxiety about evidence and process was particularly relevant when the intelligence was especially 'soft'-feelings or intuitions that were difficult to resolve into a coherent, compelling reconstruction of an incident or concern. Efforts to make soft intelligence hard thus risked creating 'forbidden knowledge': dangerous to know or share. CONCLUSIONS: The legal and bureaucratic considerations that govern formal channels for the voicing of concerns may, perversely, inhibit staff from speaking up. Leaders responsible for quality and safety should consider complementing formal mechanisms with alternative, informal opportunities for listening to concerns. PMID- 29459366 TI - Engorged medullary vein on CT angiography in patients with dural arteriovenous fistula: prevalence, types, and comparison between regional and extensive types. AB - BACKGROUND AND PURPOSE: Engorged medullary vein (EMV) in patients with intracranial dural arteriovenous fistula (DAVF) suggests venous congestion. The aim of this study is to investigate its prevalence, pattern, and correlation with clinical findings. MATERIALS AND METHODS: CT angiography (CTA) raw data of DAVF were used for multiplanar reconstruction and then analyzed for the presence and pattern of EMV, which is defined as a dilated vein in the cerebral white matter. Patients with EMV were divided into two groups: regional and extensive. Regional type is defined as EMV limited to one cerebral hemisphere or cerebellum without evidence of subcortical calcification. Extensive type is defined as EMV involvement of more than one cerebral hemisphere or both the cerebrum and cerebellum. Descriptive analysis of clinical information, DAVF characteristics, and other imaging findings was conducted. Clinical information, including demographic data, clinical presentation, and hemorrhage, were correlated with both types of EMV. RESULTS: Among 192 eligible patients with DAVF, 71 (37%) had EMV. Patients with EMV were older (63 years vs 56 years, P=0.02), with DAVF more often at the transverse and sigmoid sinus (P<0.001), and more often presented with aggressive symptoms (59% vs 34%, P=0.02) than non-EMV patients, but there was no difference in the presentation of hemorrhage (15% vs 16%, P=0.99). Patients with regional EMV had a higher proportion of hemorrhage than those with the extensive type (24% vs 0%, P=0.006). CONCLUSIONS: EMV in patients with DAVF is associated with an aggressive manifestation. Regional type EMV is associated with a higher risk of a hemorrhagic presentation. PMID- 29459367 TI - Endovascular thrombectomy beyond 12 hours of stroke onset: a stroke network's experience of late intervention. AB - BACKGROUND: Selected patients with proximal anterior circulation ischemic stroke who demonstrate limited infarct and sufficient penumbra may benefit from endovascular thrombectomy (EVT) beyond conventional time limits. OBJECTIVE: To perform a retrospective review of all cases of EVT performed at our institution for proximal anterior circulation acute ischemic stroke with onset >12 hours. MATERIALS AND METHODS: Patients were assessed with non-contrast CT brain and multiphase CT angiography, with Alberta Stroke Program Early CT Score (ASPECTS) and collateral grade informing patient selection. Data, including patient demographics, workflow, neuroimaging findings, procedural details, recanalization rates, and 90-day functional outcomes, were collected. RESULTS: Of the 542 consecutive endovascular thrombectomy cases performed during the study period, 25 (4.6%) were >12 hours from stroke onset. Median age was 69 years (IQR 55-80), median National Institute of Health Stroke Scale score on presentation was 14 (IQR 11-18.5), median ASPECTS was 8 (IQR 8-9), and rate of moderate-good collateral status was 96% (n=24). Median time to groin puncture was 14 hours 40 min (IQR 12 hours 36 min - 16 hours 18 min). Rate of successful recanalization (modified Thrombolysis in Cerebral infarction 2b-3) was 88% (n=22). Rate of functional independence (90-day modified Rankin Scale score 0-2) was 52% (n=13). There were no cases of symptomatic intracranial haemorrhage and 90-day mortality rate was 12% (n=3). CONCLUSION: With the use of ASPECTS and collateral grade to guide patient selection, good functional outcome with acceptable safety parameters may be achieved in patients undergoing EVT beyond 12 hours from stroke onset. PMID- 29459368 TI - Isolated intraventricular hemorrhage secondary to dural arteriovenous fistula. AB - Isolated intraventricular hemorrhage due to dural arteriovenous fistula (dAVF) is extremely rare and has been reported only a few times in the literature. The pathophysiological cause of isolated intraventricular hemorrhage in these cases was hypothetically attributed to retrograde venous flow into subependymal vessels, although none of these cases demonstrated radiographic evidence of such reflux. We present the first case of a dAVF with radiographic evidence of severe cortical venous reflux into the subependymal venous network causing isolated intraventricular hemorrhage, thus lending proof for the underlying pathophysiology. Furthermore, ours is the first case of dAVF with isolated intraventricular hemorrhage that was successfully treated using multimodality transvenous and transarterial embolization techniques. In cases of high-grade dAVF, multimodality treatment may offer the greatest chance for success, and should be strongly considered for management. PMID- 29459369 TI - The Nucleus Reuniens Controls Long-Range Hippocampo-Prefrontal Gamma Synchronization during Slow Oscillations. AB - Gamma oscillations are involved in long-range coupling of distant regions that support various cognitive operations. Here we show in adult male rats that synchronized bursts of gamma oscillations bind the hippocampus (HPC) and prefrontal cortex (mPFC) during slow oscillations and slow-wave sleep, a brain state that is central for consolidation of memory traces. These gamma bursts entrained the firing of the local HPC and mPFC neuronal populations. Neurons of the nucleus reuniens (NR), which is a structural and functional hub between HPC and mPFC, demonstrated a specific increase in their firing before gamma burst onset, suggesting their involvement in HPC-mPFC binding. Chemical inactivation of NR disrupted the temporal pattern of gamma bursts and their synchronization, as well as mPFC neuronal firing. We propose that the NR drives long-range hippocampo prefrontal coupling via gamma bursts providing temporal windows for information exchange between the HPC and mPFC during slow-wave sleep.SIGNIFICANCE STATEMENT Long-range coupling between hippocampus (HPC) and prefrontal cortex (mPFC) is believed to support numerous cognitive functions, including memory consolidation occurring during sleep. Gamma-band synchronization is a fundamental process in many neuronal operations and is instrumental in long-range coupling. Recent evidence highlights the role of nucleus reuniens (NR) in consolidation; however, how it influences hippocampo-prefrontal coupling is unknown. In this study, we show that HPC and mPFC are synchronized by gamma bursts during slow oscillations in anesthesia and natural sleep. By manipulating and recording the NR-HPC-mPFC network, we provide evidence that the NR actively promotes this long-range gamma coupling. This coupling provides the hippocampo-prefrontal circuit with a novel mechanism to exchange information during slow-wave sleep. PMID- 29459370 TI - Visual Working Memory Is Independent of the Cortical Spacing Between Memoranda. AB - The sensory recruitment hypothesis states that visual short-term memory is maintained in the same visual cortical areas that initially encode a stimulus' features. Although it is well established that the distance between features in visual cortex determines their visibility, a limitation known as crowding, it is unknown whether short-term memory is similarly constrained by the cortical spacing of memory items. Here, we investigated whether the cortical spacing between sequentially presented memoranda affects the fidelity of memory in humans (of both sexes). In a first experiment, we varied cortical spacing by taking advantage of the log-scaling of visual cortex with eccentricity, presenting memoranda in peripheral vision sequentially along either the radial or tangential visual axis with respect to the fovea. In a second experiment, we presented memoranda sequentially either within or beyond the critical spacing of visual crowding, a distance within which visual features cannot be perceptually distinguished due to their nearby cortical representations. In both experiments and across multiple measures, we found strong evidence that the ability to maintain visual features in memory is unaffected by cortical spacing. These results indicate that the neural architecture underpinning working memory has properties inconsistent with the known behavior of sensory neurons in visual cortex. Instead, the dissociation between perceptual and memory representations supports a role of higher cortical areas such as posterior parietal or prefrontal regions or may involve an as yet unspecified mechanism in visual cortex in which stimulus features are bound to their temporal order.SIGNIFICANCE STATEMENT Although much is known about the resolution with which we can remember visual objects, the cortical representation of items held in short-term memory remains contentious. A popular hypothesis suggests that memory of visual features is maintained via the recruitment of the same neural architecture in sensory cortex that encodes stimuli. We investigated this claim by manipulating the spacing in visual cortex between sequentially presented memoranda such that some items shared cortical representations more than others while preventing perceptual interference between stimuli. We found clear evidence that short-term memory is independent of the intracortical spacing of memoranda, revealing a dissociation between perceptual and memory representations. Our data indicate that working memory relies on different neural mechanisms from sensory perception. PMID- 29459372 TI - Detecting Unattended Stimuli Depends on the Phase of Prestimulus Neural Oscillations. AB - Neural oscillations appear important for perception and attention processes because stimulus detection is dependent upon the phase of 7-11 Hz oscillations before stimulus onset. Previous work has examined stimulus detection at attended locations, but it is unknown whether unattended locations are also subject to phasic modulation by ongoing oscillatory activity, as would be predicted by theories proposing a role for neural oscillations in organizing general neural processing. Here, we recorded brain activity with EEG while human participants of both sexes detected brief visual targets preceded by a spatial cue and determined whether performance for cued (attended) and uncued (unattended) targets was influenced by oscillatory phase across a range of frequencies. Detection of both attended and unattended targets depended upon an ~5 Hz theta rhythm and an ~11-15 Hz alpha rhythm. Critically, detection of unattended stimuli was more strongly modulated by the phase of theta oscillations than was detection of attended stimuli, suggesting that attentional allocation involves a disengagement from ongoing theta sampling. There was no attention-related difference in the strength of alpha phase dependence, consistent with a perceptual rather than attentional role of oscillatory phase in this frequency range. These results demonstrate the importance of neural oscillations in modulating visual processing at both attended and unattended locations and clarify one way in which attention may produce its effects: through disengagement from low-frequency sampling at attended locations.SIGNIFICANCE STATEMENT Past work on the interaction between oscillatory phase and neural processing has shown the involvement of posterior ~7 11 Hz oscillations in visual processing. Most studies, however, have presented stimuli at attended locations, making it difficult to disentangle frequencies related to attention from those related to perception. Here, we compared the oscillatory frequencies involved in the detection of attended and unattended stimuli and found that ~11-15 Hz oscillations were related to perception independently of attention, whereas ~5 Hz oscillations were more prominent for the detection of unattended stimuli. This work demonstrates the importance of neural oscillations for mediating stimulus processing at both attended and unattended locations and clarifies the different oscillatory frequencies involved in attention and perception. PMID- 29459371 TI - Dendritic A-Current in Rhythmically Active PreBotzinger Complex Neurons in Organotypic Cultures from Newborn Mice. AB - The brainstem preBotzinger complex (preBotC) generates the inspiratory rhythm for breathing. The onset of neural activity that precipitates the inspiratory phase of the respiratory cycle may depend on the activity of type-1 preBotC neurons, which exhibit a transient outward K+ current, IA Inspiratory rhythm generation can be studied ex vivo because the preBotC remains rhythmically active in vitro, both in acute brainstem slices and organotypic cultures. Advantageous optical conditions in organotypic slice cultures from newborn mice of either sex allowed us to investigate how IA impacts Ca2+ transients occurring in the dendrites of rhythmically active type-1 preBotC neurons. The amplitude of dendritic Ca2+ transients evoked via voltage increases originating from the soma significantly increased after an IA antagonist, 4-aminopyridine (4-AP), was applied to the perfusion bath or to local dendritic regions. Similarly, glutamate-evoked postsynaptic depolarizations recorded at the soma increased in amplitude when 4 AP was coapplied with glutamate at distal dendritic locations. We conclude that IA is expressed on type-1 preBotC neuron dendrites. We propose that IA filters synaptic input, shunting sparse excitation, while enabling temporally summated events to pass more readily as a result of IA inactivation. Dendritic IA in rhythmically active preBotC neurons could thus ensure that inspiratory motor activity does not occur until excitatory synaptic drive is synchronized and well coordinated among cellular constituents of the preBotC during inspiratory rhythmogenesis. The biophysical properties of dendritic IA might thus promote robustness and regularity of breathing rhythms.SIGNIFICANCE STATEMENT Brainstem neurons in the preBotC generate the oscillatory activity that underlies breathing. PreBotC neurons express voltage-dependent currents that can influence inspiratory activity, among which is a transient potassium current (IA) previously identified in a rhythmogenic excitatory subset of type-1 preBotC neurons. We sought to determine whether IA is expressed in the dendrites of preBotC. We found that dendrites of type-1 preBotC neurons indeed express IA, which may aid in shunting sparse non-summating synaptic inputs, while enabling strong summating excitatory inputs to readily pass and thus influence somatic membrane potential trajectory. The subcellular distribution of IA in rhythmically active neurons of the preBotC may thus be critical for producing well coordinated ensemble activity during inspiratory burst formation. PMID- 29459373 TI - Neurobiological Mechanisms of Responding to Injustice. AB - People are particularly sensitive to injustice. Accordingly, deeper knowledge regarding the processes that underlie the perception of injustice, and the subsequent decisions to either punish transgressors or compensate victims, is of important social value. By combining a novel decision-making paradigm with functional neuroimaging, we identified specific brain networks that are involved with both the perception of, and response to, social injustice, with reward related regions preferentially involved in punishment compared with compensation. Developing a computational model of punishment allowed for disentangling the neural mechanisms and psychological motives underlying decisions of whether to punish and, subsequently, of how severely to punish. Results show that the neural mechanisms underlying punishment differ depending on whether one is directly affected by the injustice, or whether one is a third-party observer of a violation occurring to another. Specifically, the anterior insula was involved in decisions to punish following harm, whereas, in third-party scenarios, we found amygdala activity associated with punishment severity. Additionally, we used a pharmacological intervention using oxytocin, and found that oxytocin influenced participants' fairness expectations, and in particular enhanced the frequency of low punishments. Together, these results not only provide more insight into the fundamental brain mechanisms underlying punishment and compensation, but also illustrate the importance of taking an explorative, multimethod approach when unraveling the complex components of everyday decision-making.SIGNIFICANCE STATEMENT The perception of injustice is a fundamental precursor to many disagreements, from small struggles at the dinner table to wasteful conflict between cultures and countries. Despite its clear importance, relatively little is known about how the brain processes these violations. Taking an interdisciplinary approach, we combine methods from neuroscience, psychology, and economics to explore the neurobiological mechanisms involved in both the perception of injustice as well as the punishment and compensation decisions that follow. Using a novel behavioral paradigm, we identified specific brain networks, developed a computational model of punishment, and found that administrating the neuropeptide oxytocin increases the administration of low punishments of norm violations in particular. Results provide valuable insights into the fundamental neurobiological mechanisms underlying social injustice. PMID- 29459376 TI - Surgeons urge NHS England to ban minimum waits.

PMID- 29459374 TI - Rescue of Learning and Memory Deficits in the Human Nonsyndromic Intellectual Disability Cereblon Knock-Out Mouse Model by Targeting the AMP-Activated Protein Kinase-mTORC1 Translational Pathway. AB - A homozygous nonsense mutation in the cereblon (CRBN) gene results in autosomal recessive, nonsyndromic intellectual disability that is devoid of other phenotypic features, suggesting a critical role of CRBN in mediating learning and memory. In this study, we demonstrate that adult male Crbn knock-out (CrbnKO) mice exhibit deficits in hippocampal-dependent learning and memory tasks that are recapitulated by focal knock-out of Crbn in the adult dorsal hippocampus, with no changes in social or repetitive behavior. Cellular studies identify deficits in long-term potentiation at Schaffer collateral CA1 synapses. We further show that Crbn is robustly expressed in the mouse hippocampus and CrbnKO mice exhibit hyperphosphorylated levels of AMPKalpha (Thr172). Examination of processes downstream of AMP-activated protein kinase (AMPK) finds that CrbnKO mice have a selective impairment in mediators of the mTORC1 translation initiation pathway in parallel with lower protein levels of postsynaptic density glutamatergic proteins and higher levels of excitatory presynaptic markers in the hippocampus with no change in markers of the unfolded protein response or autophagy pathways. Acute pharmacological inhibition of AMPK activity in adult CrbnKO mice rescues learning and memory deficits and normalizes hippocampal mTORC1 activity and postsynaptic glutamatergic proteins without altering excitatory presynaptic markers. Thus, this study identifies that loss of Crbn results in learning, memory, and synaptic defects as a consequence of exaggerated AMPK activity, inhibition of mTORC1 signaling, and decreased glutamatergic synaptic proteins. Thus, CrbnKO mice serve as an ideal model of intellectual disability to further explore molecular mechanisms of learning and memory.SIGNIFICANCE STATEMENT Intellectual disability (ID) is one of the most common neurodevelopmental disorders. The cereblon (CRBN) gene has been linked to autosomal recessive, nonsyndromic ID, characterized by an intelligence quotient between 50 and 70 but devoid of other phenotypic features, making cereblon an ideal protein for the study of the fundamental aspects of learning and memory. Here, using the cereblon knock-out mouse model, we show that cereblon deficiency disrupts learning, memory, and synaptic function via AMP activated protein kinase hyperactivity, downregulation of mTORC1, and dysregulation of excitatory synapses, with no changes in social or repetitive behaviors, consistent with findings in the human population. This establishes the cereblon knock-out mouse as a model of pure ID without the confounding behavioral phenotypes associated with other current models of ID. PMID- 29459378 TI - Role of allostatic load and health behaviours in explaining socioeconomic disparities in mortality: a structural equation modelling approach. AB - BACKGROUND: The relationship between socioeconomic status and mortality has been well established; however, the extent to which biological factors mediate this relationship is less clear, and empirical evidence from non-Western settings is limited. Allostasis, a cumulative measure of physiological dysregulation, has been proposed as the underlying mechanism linking socioeconomic status to adverse health outcomes. The current study aimed to ascertain the contribution of allostatic load (AL) and health behaviours to socioeconomic inequalities in mortality among Korean adults. METHODS: The sample comprised 70 713 middle-aged and older-aged adults, aged 40-79 years from the Korean Metabolic Syndrome Mortality Study. Using structural equation modelling (SEM), mediation analyses were performed to estimate the effects of socioeconomic position (SEP) on mortality over the follow-up and the extent to which AL, physical exercise and non-smoking status mediate the association between SEP and mortality. RESULTS: A total of 5618 deaths (7.9%) occurred during the mean follow-up of 15.2 years (SD 2.9). SEM confirmed a direct significant effect of SEP on mortality, as well as significant indirect paths through AL, physical exercise and non-smoking status. CONCLUSIONS: Our findings provide support for the mediating role of AL and health behaviours in the link between SEP and mortality. Policies designed to reduce social disparities in mortality in the long term should primarily focus on reducing stress and promoting healthy lifestyles among the socially disadvantaged groups. Future studies should further assess the role of other mediators such as psychosocial factors, which may contribute to socioeconomic inequalities in mortality. PMID- 29459377 TI - Gender differences in the use of anti-infective medications before and after widowhood: a register-based study. AB - BACKGROUND: Recent findings suggest that bereavement due to spousal loss is associated with a decline in general immune functions, and thus to increased susceptibility to infections among widowed individuals. The present study aims to investigate whether spousal loss weakens immune defences more among men than among women using a 5% random sample of the total Danish population, and anti infective medication use as a proxy for immune response. METHODS: We followed 6076 Danish individuals (67% women) aged >=50 from 5 years before and up to 5 years after widowhood to examine changes in prescriptions of anti-infectives for systemic use. RESULTS: Women used more anti-infective drugs both before and after spousal loss (women: OR= 1.31; 95% CI 1.21 to 1.42). The age-related changes in the use of anti-infective medications in the period before widowhood were similar to that in the period after widowhood among both men and women. Also, age-related changes in the use of anti-infective medications were similar in both genders. CONCLUSIONS: The present study shows that individuals are more likely to use anti infective medication after being widowed than before being widowed, but this change is likely to be related to increasing age and it is similar in both genders.

PMID- 29459380 TI - Convergent molecular defects underpin diverse neurodegenerative diseases. AB - In our ageing population, neurodegenerative disorders carry an enormous personal, societal and economic burden. Although neurodegenerative diseases are often thought of as clinicopathological entities, increasing evidence suggests a considerable overlap in the molecular underpinnings of their pathogenesis. Such overlapping biological processes include the handling of misfolded proteins, defective organelle trafficking, RNA processing, synaptic health and neuroinflammation. Collectively but in different proportions, these biological processes in neurons or non-neuronal cells lead to regionally distinct patterns of neuronal vulnerability and progression of pathology that could explain the disease symptomology. With the advent of patient-derived cellular models and novel genetic manipulation tools, we are now able to interrogate this commonality despite the cellular complexity of the brain in order to develop novel therapeutic strategies to prevent or arrest neurodegeneration. Here, we describe broadly these concepts and their relevance across neurodegenerative diseases. PMID- 29459381 TI - A Patient with Hemolytic Uremic Syndrome and Kidney Failure.

PMID- 29459388 TI - UK news media representations of smoking, smoking policies and tobacco bans in prisons. AB - BACKGROUND: Prisoner smoking rates remain high, resulting in secondhand smoke exposures for prison staff and non-smoker prisoners. Several jurisdictions have introduced prison smoking bans with little evidence of resulting disorder. Successful implementation of such bans requires staff support. As news media representations of health and other issues shape public views and as prison smoking bans are being introduced in the UK, we conducted content analysis of UK news media to explore representations of smoking in prisons and smoke-free prisons. METHODS: We searched 64 national and local newspapers and 5 broadcast media published over 17 months during 2015-2016, and conducted thematic analysis of relevant coverage in 106 articles/broadcasts. RESULTS: Coverage was relatively infrequent and lacked in-depth engagement with the issues. It tended to reinforce a negative view of prisoners, avoid explicit concern for prisoner or prison staff health and largely ignore the health gains of smoke-free policies. Most coverage failed to discuss appropriate responses or support for cessation in the prison context, or factors associated with high prisoner smoking rates. Half the articles/broadcasts included coverage suggesting smoke-free prisons might lead to unrest or instability. CONCLUSIONS: Negative news media representations of prisoners and prison smoking bans may impact key stakeholders' views (eg, prison staff, policy-makers) on the introduction of smoke-free prison policies. Policy makers' communications when engaging in discussion around smoke-free prison policies should draw on the generally smooth transitions to smoke-free prisons to date, and on evidence on health benefits of smoke-free environments and smoking cessation. PMID- 29459389 TI - Tobacco industry misappropriation of American Indian culture and traditional tobacco. AB - OBJECTIVE: Describe the extent to which tobacco industry marketing tactics incorporated American Indian culture and traditional tobacco. METHODS: A keyword search of industry documents was conducted using document archives from the Truth Tobacco Documents Library. Tobacco industry documents (n=76) were analysed for themes. RESULTS: Tobacco industry marketing tactics have incorporated American Indian culture and traditional tobacco since at least the 1930s, with these tactics prominently highlighted during the 1990s with Natural American Spirit cigarettes. Documents revealed the use of American Indian imagery such as traditional headdresses and other cultural symbols in product branding and the portrayal of harmful stereotypes of Native people in advertising. The historical and cultural significance of traditional tobacco was used to validate commercially available tobacco. CONCLUSIONS: The tobacco industry has misappropriated culture and traditional tobacco by misrepresenting American Indian traditions, values and beliefs to market and sell their products for profit. Findings underscore the need for ongoing monitoring of tobacco industry marketing tactics directed at exploiting Native culture and counter-marketing tactics that raise awareness about the distinction between commercial and traditional tobacco use. Such efforts should be embedded within a culturally sensitive framework to reduce the burden of commercial tobacco use. PMID- 29459390 TI - First Pass Effect: A New Measure for Stroke Thrombectomy Devices. AB - BACKGROUND AND PURPOSE: In acute ischemic stroke, fast and complete recanalization of the occluded vessel is associated with improved outcomes. We describe a novel measure for newer generation devices: the first pass effect (FPE). FPE is defined as achieving a complete recanalization with a single thrombectomy device pass. METHODS: The North American Solitaire Acute Stroke Registry database was used to identify a FPE subgroup. Their baseline features and clinical outcomes were compared with non-FPE patients. Clinical outcome measures included 90-days modified Rankin Scale score, National Institutes of Health Stroke Scale score, mortality, and symptomatic intracranial hemorrhage. Multivariate analyses were performed to determine whether FPE independently resulted in improved outcomes and to identify predictors of FPE. RESULTS: A total of 354 acute ischemic stroke patients underwent thrombectomy in the North American Solitaire Acute Stroke registry. FPE was achieved in 89 out of 354 (25.1%). More middle cerebral artery occlusions (64% versus 52.5%) and fewer internal carotid artery occlusions (10.1% versus 27.7%) were present in the FPE group. Balloon guide catheters were used more frequently with FPE (64.0% versus 34.7%). Median time to revascularization was significantly faster in the FPE group (median 34 versus 60 minutes; P=0.0003). FPE was an independent predictor of good clinical outcome (modified Rankin Scale score <=2 was seen in 61.3% in FPE versus 35.3% in non-FPE cohort; P=0.013; odds ratio, 1.7; 95% confidence interval, 1.1-2.7). The independent predictors of achieving FPE were use of balloon guide catheters and non-internal carotid artery terminus occlusion. CONCLUSIONS: The achievement of complete revascularization from a single Solitaire thrombectomy device pass (FPE) is associated with significantly higher rates of good clinical outcome. The FPE is more frequently associated with the use of balloon guide catheters and less likely to be achieved with internal carotid artery terminus occlusion.

PMID- 29459391 TI - Los Angeles Motor Scale to Identify Large Vessel Occlusion: Prehospital Validation and Comparison With Other Screens. AB - BACKGROUND AND PURPOSE: Prehospital scales have been developed to identify patients with acute cerebral ischemia (ACI) because of large vessel occlusion (LVO) for direct routing to Comprehensive Stroke Centers (CSCs), but few have been validated in the prehospital setting, and their impact on routing of patients with intracranial hemorrhage has not been delineated. The purpose of this study was to validate the Los Angeles Motor Scale (LAMS) for LVO and CSC appropriate (LVO ACI and intracranial hemorrhage patients) recognition and compare the LAMS to other scales. METHODS: The performance of the LAMS, administered prehospital by paramedics to consecutive ambulance trial patients, was assessed in identifying (1) LVOs among all patients with ACI and (2) CSC appropriate patients among all suspected strokes. Additionally, the LAMS administered postarrival was compared concurrently with 6 other scales proposed for paramedic use and the full National Institutes of Health Stroke Scale. RESULTS: Among 94 patients, age was 70 (+/-13) and 49% female. Final diagnoses were ACI in 76% (because of LVO in 48% and non-LVO in 28%), intracranial hemorrhage in 19%, and neurovascular mimic in 5%. The LAMS administered by paramedics in the field performed moderately well in identifying LVO among patients with ACI (C statistic, 0.79; accuracy, 0.72) and CSC-appropriate among all suspected stroke transports (C statistic, 0.80; accuracy, 0.72). When concurrently performed in the emergency department postarrival, the LAMS showed comparable or better accuracy versus the 7 comparator scales, for LVO among ACI (accuracies LAMS, 0.70; other scales, 0.62-0.68) and CSC-appropriate (accuracies LAMS, 0.73; other scales, 0.56-0.73). CONCLUSIONS: The LAMS performed in the field by paramedics identifies LVO and CSC-appropriate patients with good accuracy. The LAMS performs comparably or better than more extended prehospital scales and the full National Institutes of Health Stroke Scale.

PMID- 29459394 TI - Hyperintense Vessels, Collateralization, and Functional Outcome in Patients With Stroke Receiving Endovascular Treatment. AB - BACKGROUND AND PURPOSE: Fluid-attenuated inversion recovery hyperintense vessels (FHV) are frequently observed on magnetic resonance imaging in acute stroke patients with proximal vessel occlusion. Whether FHV can serve as a surrogate for the collateral status and predict functional outcome of patients is still a matter of debate. METHODS: Acute ischemic stroke patients with M1-middle cerebral artery occlusion who received magnetic resonance imaging before endovascular treatment in 3 hospitals in Germany between January 2007 and June 2016 were eligible. Quantification of FHV was performed using an FHV-Alberta Stroke Program Early CT Score (ASPECTS) rating system. Functional outcome was evaluated with the modified Rankin Scale 3 months after stroke. Collateral status of patients was graded on baseline angiography using the American Society of Interventional and Therapeutic Neuroradiology grading system. Odds for good outcome (modified Rankin Scale score, 0-2) were determined using logistic regression analyses. RESULTS: Overall, 116 patients were analyzed (median age, 74; interquartile range [IQR], 64-79; median National Institutes of Health Stroke Scale, 14; IQR, 10-19). The median FHV-ASPECTS was 2 (IQR, 1-3). Good collateral status (American Society of Interventional and Therapeutic Neuroradiology grade 3-4) on angiography was more frequently observed in patients with FHV-ASPECTS <=2 (83% versus 57%; P=0.025). Patients with an FHV-ASPECTS <=2 had a better functional outcome after 3 months (median modified Rankin Scale score, 2; IQR, 0-5), compared with patients with an FHV-ASPECTS >2 (median modified Rankin Scale score, 4; IQR, 3-6; P=0.015). In multiple regression analyses, FHV-ASPECTS <=2 was independently associated with good functional outcome (adjusted odds ratio, 5.3; 95% confidence interval, 1.5 18.2). CONCLUSIONS: Low FHV-ASPECTS is associated with both better collateral status and better 3-month functional outcome in acute stroke patients with M1 vessel occlusion. PMID- 29459395 TI - Effects of Prehospital Thrombolysis in Stroke Patients With Prestroke Dependency. AB - BACKGROUND AND PURPOSE: Data on effects of intravenous thrombolysis on outcome of patients with ischemic stroke who are dependent on assistance in activities of daily living prestroke are scarce. Recent registry based analyses in activities of daily -independent patients suggest that earlier start of intravenous thrombolysis in the prehospital setting leads to better outcomes when compared with the treatment start in hospital. We evaluated whether these observations can be corroborated in patients with prestroke dependency. METHODS: This observational, retrospective analysis included all patients with acute ischemic stroke depending on assistance before stroke who received intravenous thrombolysis either on the Stroke Emergency Mobile (STEMO) or through conventional in-hospital care (CC) in a tertiary stroke center (Charite, Campus Benjamin Franklin, Berlin) during routine care. Prespecified outcomes were modified Rankin Scale scores of 0 to 3 and survival at 3 months, as well as symptomatic intracranial hemorrhage. Outcomes were adjusted in multivariable logistic regression. RESULTS: Between February 2011 and March 2015, 122 of 427 patients (28%) treated on STEMO and 142 of 505 patients (28%) treated via CC needed assistance before stroke. Median onset-to-treatment times were 97 (interquartile range, 69-159; STEMO) and 135 (interquartile range, 98-184; CC; P<0.001) minutes. After 3 months, modified Rankin Scale scores of 0 to 3 was observed in 48 STEMO patients (39%) versus 35 CC patients (25%; P=0.01) and 86 (70%, STEMO) versus 85 (60%, CC) patients were alive (P=0.07). After adjustment, STEMO care was favorable with respect to modified Rankin Scale scores of 0 to 3 (odds ratio, 1.99; 95% confidence interval, 1.02-3.87; P=0.042) with a nonsignificant result for survival (odds ratio, 1.73; 95% confidence interval, 0.95-3.16; P=0.07). Symptomatic intracranial hemorrhage occurred in 5 STEMO versus 12 CC patients (4.2% versus 8.5%; P=0.167). CONCLUSIONS: The results of this study suggest that earlier, prehospital (as compared with in-hospital) start of intravenous thrombolysis in acute ischemic stroke may translate into better clinical outcome in patients with prestroke dependency.

PMID- 29459397 TI - Predictors of Thrombolysis Administration in Mild Stroke: Florida-Puerto Rico Collaboration to Reduce Stroke Disparities. AB - BACKGROUND AND PURPOSE: Mild stroke is the most common cause for thrombolysis exclusion in patients acutely presenting to the hospital. Thrombolysis administration in this subgroup is highly variable among different clinicians and institutions. We aim to study the predictors of thrombolysis in patients with mild ischemic stroke in the FL-PR CReSD registry (Florida-Puerto Rico Collaboration to Reduce Stroke Disparities). METHODS: Among 73 712 prospectively enrolled patients with a final diagnosis of ischemic stroke or TIA from January 2010 to April 2015, we identified 7746 cases with persistent neurological symptoms and National Institutes of Health Stroke Scale <=5 who arrived within 4 hours of symptom onset. Multilevel logistic regression analysis with generalized estimating equations was used to identify independent predictors of thrombolytic administration in the subgroup of patients without contraindications to thrombolysis. RESULTS: We included 6826 cases (final diagnosis mild stroke, 74.6% and TIA, 25.4%). Median age was 72 (interquartile range, 21); 52.7% men, 70.3% white, 12.9% black, 16.8% Hispanic; and median National Institutes of Health Stroke Scale, 2 (interquartile range, 3). Patients who received thrombolysis (n=1281, 18.7%) were younger (68 versus 72 years), had less vascular risk factors (hypertension, diabetes mellitus, and dyslipidemia), had lower risk of prior vascular disease (myocardial infarction, peripheral vascular disease, and previous stroke), and had a higher presenting median National Institutes of Health Stroke Scale (4 versus 2). In the multilevel multivariable model, early hospital arrival (arrive by 0-2 hours versus >=3.5 hours; odds ratio [OR], 8.16; 95% confidence interval [CI], 4.76-13.98), higher National Institutes of Health Stroke Scale (OR, 1.87; 95% CI, 1.77-1.98), aphasia at presentation (OR, 1.35; 95% CI, 1.12-1.62), faster door-to-computed tomography time (OR, 1.81; 95% CI, 1.53-2.15), and presenting to an academic hospital (OR, 2.02; 95% CI, 1.39-2.95) were independent predictors of thrombolysis administration. CONCLUSIONS: Mild acutely presenting stroke patients are more likely to receive thrombolysis if they are young, white, or Hispanic and arrive early to the hospital with more severe neurological presentation. Identification of predictors of thrombolysis is important in design of future studies to assess the use of thrombolysis for mild stroke. PMID- 29459398 TI - Vulnerability to Infarction During Cerebral Ischemia in Migraine Sufferers. AB - BACKGROUND AND PURPOSE: Cerebral hyperexcitability in migraine experiencers might sensitize brain tissue to ischemia. We investigated whether a personal history of migraine is associated with vulnerability to brain ischemia in humans. METHODS: Multicenter cohort study of patients with acute ischemic stroke who underwent a brain computed tomography perfusion and were scheduled to undergo reperfusion therapy. In a case-control design, we compared the proportion of subjects with no mismatch, the volume of penumbra salvaged, as well as the final infarct size in a group of patients with migraine and a group of patients with no history of migraine. RESULTS: We included 61 patients with migraine (34 [55.7%] men; mean age, 52.2+/-15.1 years; migraine without aura/migraine with aura, 44/17) and 61 patients with no history of migraine. The proportion of no-mismatch among migraineurs was significantly higher than among nonmigraineurs (17 [27.9%] versus 7 [11.5%]; P=0.039) and was more prominent among patients with migraine with aura (6 [35.3%]; P=0.030) while it was nonsignificantly increased in patients with migraine without aura (11 [25.0%]; P=0.114). Migraine, especially migraine with aura, was independently associated with a no-mismatch pattern (odds ratio, 2.65; 95% CI, 0.95-7.41 for migraine; odds ratio, 5.54; 95% CI, 1.28-23.99 for migraine with aura), and there was a linear decrease of the proportion of patients with migraine with aura with increasing quartiles of mismatch volumes. Patients with migraine with aura had also smaller volumes of salvaged penumbra (9.8+/-41.2 mL) compared with patients with migraine without aura (36.4+/-54.1 mL) and patients with no migraine (45.1+/-55.0 mL; P=0.056). Conversely, there was no difference in final infarct size among the 3 migraine subgroups (P=0.312). CONCLUSIONS: Migraine is likely to increase individual vulnerability to ischemic stroke during the process of acute brain ischemia and might represent, therefore, a potential new therapeutic target against occurrence and progression of the ischemic damage. PMID- 29459400 TI - Sperm form and function: what do we know about the role of sexual selection? AB - Sperm morphological variation has attracted considerable interest and generated a wealth of predominantly descriptive studies over the past three centuries. Yet, apart from biophysical studies linking sperm morphology to swimming velocity, surprisingly little is known about the adaptive significance of sperm form and the selective processes underlying its tremendous diversification throughout the animal kingdom. Here, we first discuss the challenges of examining sperm morphology in an evolutionary context and why our understanding of it is far from complete. Then, we review empirical evidence for how sexual selection theory applies to the evolution of sperm form and function, including putative secondary sexual traits borne by sperm. PMID- 29459399 TI - External Validation of Risk Scores for Major Bleeding in a Population-Based Cohort of Transient Ischemic Attack and Ischemic Stroke Patients. AB - BACKGROUND AND PURPOSE: The S2TOP-BLEED score may help to identify patients at high risk of bleeding on antiplatelet drugs after a transient ischemic attack or ischemic stroke. The score was derived on trial populations, and its performance in a real-world setting is unknown. We aimed to externally validate the S2TOP BLEED score for major bleeding in a population-based cohort and to compare its performance with other risk scores for bleeding. METHODS: We studied risk of bleeding in 2072 patients with a transient ischemic attack or ischemic stroke on antiplatelet agents in the population-based OXVASC (Oxford Vascular Study) according to 3 scores: S2TOP-BLEED, REACH, and Intracranial-B2LEED3S. Performance was assessed with C statistics and calibration plots. RESULTS: During 8302 patient-years of follow-up, 117 patients had a major bleed. The S2TOP-BLEED score showed a C statistic of 0.69 (95% confidence interval [CI], 0.64-0.73) and accurate calibration for 3-year risk of major bleeding. The S2TOP-BLEED score was much more predictive of fatal bleeding than nonmajor bleeding (C statistics 0.77; 95% CI, 0.69-0.85 and 0.50; 95% CI, 0.44-0.58). The REACH score had a C statistic of 0.63 (95% CI, 0.58-0.69) for major bleeding and the Intracranial-B2LEED3S score a C statistic of 0.60 (95% CI, 0.51-0.70) for intracranial bleeding. The ratio of ischemic events versus bleeds decreased across risk groups of bleeding from 6.6:1 in the low-risk group to 1.8:1 in the high-risk group. CONCLUSIONS: The S2TOP-BLEED score shows modest performance in a population-based cohort of patients with a transient ischemic attack or ischemic stroke. Although bleeding risks were associated with risks of ischemic events, risk stratification may still be useful to identify a subgroup of patients at particularly high risk of bleeding, in whom preventive measures are indicated. PMID- 29459401 TI - Low-dose gonadotropin induction of ovulation in anovulatory women: still needed in the age of IVF. AB - Low-dose, step-up gonadotropin is the treatment of choice for women with polycystic ovary syndrome (PCOS) who have not conceived after anti-oestrogen treatment and as an effective alternative to pulsatile GnRH in women with hypogonadotropic hypogonadism (HH). There has been, however, no large-scale, comparative study between the two groups using low-dose gonadotropins. Here, we performed a retrospective, comparative analysis, in a single clinic database, of efficacy and safety of induction of ovulation using low-dose gonadotropins in 364 women with PCOS and 80 women with HH. The rate of ovulation was high in both PCOS (83%) and HH (84%) but mono-follicular, ovulatory cycles were more prevalent in PCOS than in HH (77% vs 53%, P < 0.0001) and the proportion of cycles that were abandoned was higher in HH than in PCOS (25% vs 15%, P < 0.0001). The median threshold dose of gonadotropin required to induce ovulation was 75 IU/day in PCOS and 113 IU/day in HH (P < 0.001) and the range of doses was greater in HH women. Forty-nine percent of women with PCOS and 65% of those with HH conceived (more than 90% within 6 cycles of treatment) and had at least one pregnancy. Multiple pregnancies (all twins) occurred in only 4% of women with PCOS and 5% of those with HH. These findings emphasise the efficacy and safety of low-dose gonadotropin treatment for both clomiphene-resistant women with PCOS and those with HH. These results highlight the importance of choosing the more physiological approach of gonadotropin induction of ovulation in both groups as the most appropriate treatment, in preference to IVF. PMID- 29459402 TI - Expression and function of Pdcd4 in mouse endometrium during early pregnancy. AB - Embryo implantation is a complex process involving synchronised crosstalk between a receptive endometrium and functional blastocysts. Apoptosis plays an important role in this process as well as in the maintenance of pregnancy. In this study, we analysed the expression pattern of programmed cell death 4 (Pdcd4), a gene associated with apoptosis in the mouse endometrium, during early pregnancy and pseudopregnancy by real-time quantitative polymerase chain reaction, in situ hybridisation, Western blotting and immunohistochemistry. The results showed that Pdcd4 was increased along with days of pregnancy and significantly reduced at implantation sites (IS) from day 5 of pregnancy (D5). The level of Pdcd4 at IS was substantially lower than that at interimplantation sites (IIS) on D6 and D7. In addition, Pdcd4 expression in the endometrium was reduced in response to artificially induced decidualisation in vivo and in vitro Downregulation of Pdcd4 gene expression in cultured primary stromal cells promoted decidualisation, while upregulation inhibited the decidualisation process by increasing apoptosis. These results demonstrate that Pdcd4 is involved in stromal cell decidualisation by mediating apoptosis and therefore plays a role in embryo implantation in mice. PMID- 29459403 TI - The Alternative NF-kappaB Pathway in Regulatory T Cell Homeostasis and Suppressive Function. AB - CD4+Foxp3+ regulatory T cells (Tregs) are essential regulators of immune responses. Perturbation of Treg homeostasis or function can lead to uncontrolled inflammation and autoimmunity. Therefore, understanding the molecular mechanisms involved in Treg biology remains an active area of investigation. It has been shown previously that the NF-kappaB family of transcription factors, in particular, the canonical pathway subunits, c-Rel and p65, are crucial for the development, maintenance, and function of Tregs. However, the role of the alternative NF-kappaB pathway components, p100 and RelB, in Treg biology remains unclear. In this article, we show that conditional deletion of the p100 gene, nfkb2, in Tregs, resulted in massive inflammation because of impaired suppressive function of nfkb2-deficient Tregs. Surprisingly, mice lacking RelB in Tregs did not exhibit the same phenotype. Instead, deletion of both relb and nfkb2 rescued the inflammatory phenotype, demonstrating an essential role for p100 as an inhibitor of RelB in Tregs. Our data therefore illustrate a new role for the alternative NF-kappaB signaling pathway in Tregs that has implications for the understanding of molecular pathways driving tolerance and immunity. PMID- 29459404 TI - Septic Shock Shapes B Cell Response toward an Exhausted-like/Immunoregulatory Profile in Patients. AB - Septic shock is accompanied by the development of immune dysfunctions whose intensity and duration are associated with increased risk of secondary infections and mortality. Although B lymphocytes play a pivotal role in the immune response to infections, no comprehensive exploration of circulating B cell status has been performed during the immunosuppressive phase of septic shock. Thus, our aim was to extensively characterize the phenotype and function of B cells in septic shock, including IL-10 production. Circulating B lymphocyte phenotype and function were evaluated by flow cytometry on fresh whole blood and after ex vivo stimulation in adult septic shock patients sampled at day 1, 3, and 6 after the onset of shock. The circulating B cell number was reduced in septic shock patients, whereas the B cell proportion among total lymphocytes was increased. The remaining circulating B lymphocytes presented with decreased MHC class II expression and increased CD21low CD95high exhausted-like phenotype but showed no change in maturation status. Circulating B cell functions were markedly altered after sepsis with reduced ex vivo activation and proliferation capacities. Finally, B cell response after septic shock was characterized by a clear plasmacytosis and an increased IL-10 production in remaining B cells from patients after ex vivo stimulation. During the sepsis-induced immunosuppression phase, B cell response is altered and is oriented toward an exhausted like/immunoregulatory profile. Further studies are now needed to confirm the immunoregulatory properties of B lymphocytes and evaluate their role in sepsis induced immunosuppression. PMID- 29459405 TI - alphaMbeta2 Is Antiatherogenic in Female but Not Male Mice. AB - Atherosclerosis is a complex inflammatory process characterized by monocyte recruitment into the arterial wall, their differentiation into macrophages, and lipid accumulation. Because integrin alphaMbeta2 (CD11b/CD18) mediates multiple diverse functions of leukocytes, we examined its role in atherogenesis. alphaM-/ /ApoE-/- and ApoE-/- mice were fed a control or high fat diet for 3 or 16 wk to induce atherogenesis. Unexpectedly, alphaM deficiency accelerated development of atherosclerosis in female but not in male mice. The size of aortic root lesions was 3-4.5-fold larger in female alphaM-/-/ApoE-/- than in ApoE-/- mice. Monocyte and macrophage content within the lesions was increased 2.5-fold in female alphaM /-/ApoE-/- mice due to enhanced proliferation. alphaMbeta2 elimination promoted gender-dependent foam cell formation due to enhanced uptake of cholesterol by alphaM-/-/ApoE-/- macrophages. This difference was attributed to enhanced expression of lipid uptake receptors, CD36 and scavenger receptor A1 (SR-A1), in female mice. Macrophages from female alphaM-/-/ApoE-/- mice showed dramatically reduced expression of FoxM1 transcription factor and estrogen receptors (ER) alpha and beta. As their antagonists inhibited the effect of 17beta-estradiol (E2), E2 decreased CD36, SR-A1, and foam cell formation in ApoE-/- macrophages in an ERalpha- and ERbeta-dependent manner. However, female alphaM-/-/ApoE-/- macrophages failed to respond to E2 and maintained elevated CD36, SR-A1, and lipid accumulation. FoxM1 inhibition in ApoE-/- macrophages reduced ERs and enhanced CD36 and SR-A1 expression, whereas FoxM1 overexpression in alphaM-/ /ApoE-/- macrophages reversed their proatherogenic phenotype. We demonstrate a new, surprising atheroprotective role of alphaMbeta2 in female ApoE-/- mice. alphaMbeta2 maintains ER expression in macrophages and E2-dependent inhibition of foam cell formation. PMID- 29459407 TI - CrosstalkNet: A Visualization Tool for Differential Co-expression Networks and Communities. AB - Variations in physiological conditions can rewire molecular interactions between biological compartments, which can yield novel insights into gain or loss of interactions specific to perturbations of interest. Networks are a promising tool to elucidate intercellular interactions, yet exploration of these large-scale networks remains a challenge due to their high dimensionality. To retrieve and mine interactions, we developed CrosstalkNet, a user friendly, web-based network visualization tool that provides a statistical framework to infer condition specific interactions coupled with a community detection algorithm for bipartite graphs to identify significantly dense subnetworks. As a case study, we used CrosstalkNet to mine a set of 54 and 22 gene-expression profiles from breast tumor and normal samples, respectively, with epithelial and stromal compartments extracted via laser microdissection. We show how CrosstalkNet can be used to explore large-scale co-expression networks and to obtain insights into the biological processes that govern cross-talk between different tumor compartments.Significance: This web application enables researchers to mine complex networks and to decipher novel biological processes in tumor epithelial stroma cross-talk as well as in other studies of intercompartmental interactions.

PMID- 29459406 TI - TLR2 Stimulation Strengthens Intrahepatic Myeloid-Derived Cell-Mediated T Cell Tolerance through Inducing Kupffer Cell Expansion and IL-10 Production. AB - Hepatic APCs play a critical role in promoting immune tolerance in the liver. Recently, we have demonstrated that TLR2 stimulation on liver sinusoidal endothelial cells reverted their suppressive properties to induce T cell immunity. However, there is a paucity of information about how TLR2 stimulation modulates the immunological function of other hepatic APCs. In the current study, we investigated whether TLR2 stimulation influences the function of intrahepatic myeloid-derived cells (iMDCs) and elucidated the mechanisms involved in iMDC induced T cell immunity. We could show that iMDCs from C57BL/6 mice can potently suppress T cell activation in a cell contact-independent manner. Ag presentation by iMDCs leads to naive CD8 T cell tolerance. To our surprise, instead of inducing cell functional maturation, TLR2 ligand palmitoyl-3-cysteine-serine lysine-4 (P3C) stimulation further strengthens the suppressive and tolerogenic properties of iMDCs. After P3C administration, the population of Kupffer cells (KCs) of iMDCs dramatically increased. Mechanism analysis shows that KCs are essential for the enhanced inhibition of T cell activation by P3C-stimulated iMDCs. The iMDC-mediated CD8 T cell inhibition was mediated by soluble mediators, one of which was IL-10 secreted by KCs after P3C stimulation. IL-10 blockade could partially abolish iMDC-mediated T cell inhibition. Moreover, hepatitis B virus particle stimulation on iMDCs could also induce IL-10 production by the cells in a TLR2-dependent way. Our results have implications for our understanding of liver-specific tolerance and for the development of strategies to overcome T cell tolerance in situations such as chronic viral liver infections.

AB - INTRODUCTION: The importance of time in therapeutic range (TTR) in patients prescribed warfarin therapy for stroke prevention in atrial fibrillation (AF) cannot be overemphasised. AIM: To evaluate the impact of provision of TTR results during clinic visits on anticoagulation management. DESIGN: Single-centred, randomised controlled study. SETTING: Fifteen arrhythmia clinics in Hong Kong. PATIENTS: AF patients prescribed warfarin. INTERVENTIONS: Provision of TTR or no provision of TTR. MAIN OUTCOME MEASURES: A documented discussion between doctors and patients about switching warfarin to a non-vitamin K oral anticoagulant (NOAC). RESULTS: Four hundred and eighty one patients with AF prescribed warfarin were randomly assigned to (1) a TTR provision group or (2) control. Their mean age was 73.6+/-12.0 years and 60.7% were men. The mean CHA2DS2-VASc score was 3.2+/-1.6 and the mean HASBLED score was 1.7+/-1.2. The mean TTR was 63.9%+/ 29.9%. At the index clinic visit, 71 of 481 patients (14.8%) had a documented discussion about switching warfarin to a NOAC. Patients with provision of TTR results were more likely to discuss switching warfarin to a NOAC than controls (19.1% vs 10.6%, P=0.03), especially those with a TTR <65% (35.2% vs 10.6%, P<0.001). A higher proportion of patients with provision of TTR results switched to a NOAC (5.9% vs 4.1%, P=0.49). CONCLUSIONS: The provision of TTR among patients on warfarin was associated with a discussion about switching from warfarin to a NOAC in those with TTR <65%, but did not result in actual switching to a NOAC, suggesting additional barriers.

AB - Both the 1S-2S transition and the ground state hyperfine spectrum have been observed in trapped antihydrogen. The former constitutes the first observation of resonant interaction of light with an anti-atom, and the latter is the first detailed measurement of a spectral feature in antihydrogen. Owing to the narrow intrinsic linewidth of the 1S-2S transition and use of two-photon laser excitation, the transition energy can be precisely determined in both hydrogen and antihydrogen, allowing a direct comparison as a test of fundamental symmetry. The result is consistent with CPT invariance at a relative precision of around 2*10-10 This constitutes the most precise measurement of a property of antihydrogen. The hyperfine spectrum of antihydrogen is determined to a relative uncertainty of 4*10-4 The excited state and the hyperfine spectroscopy techniques currently both show sensitivity at the few 100 kHz level on the absolute scale. Here, the most recent work of the ALPHA collaboration on precision spectroscopy of antihydrogen is presented together with an outlook on improving the precision of measurements involving lasers and microwave radiation. Prospects of measuring the Lamb shift and determining the antiproton charge radius in trapped antihydrogen in the ALPHA apparatus are presented. Future perspectives of precision measurements of trapped antihydrogen in the ALPHA apparatus when the ELENA facility becomes available to experiments at CERN are discussed.This article is part of the Theo Murphy meeting issue 'Antiproton physics in the ELENA era'. PMID- 29459410 TI - Recent progress of laser spectroscopy experiments on antiprotonic helium. AB - The Atomic Spectroscopy and Collisions Using Slow Antiprotons (ASACUSA) collaboration is currently carrying out laser spectroscopy experiments on antiprotonic helium [Formula: see text] atoms at CERN's Antiproton Decelerator facility. Two-photon spectroscopic techniques have been employed to reduce the Doppler width of the measured [Formula: see text] resonance lines, and determine the atomic transition frequencies to a fractional precision of 2.3-5 parts in 109 More recently, single-photon spectroscopy of buffer-gas cooled [Formula: see text] has reached a similar precision. By comparing the results with three-body quantum electrodynamics calculations, the antiproton-to-electron mass ratio was determined as [Formula: see text], which agrees with the known proton-to-electron mass ratio with a precision of 8*10-10 The high-quality antiproton beam provided by the future Extra Low Energy Antiproton Ring (ELENA) facility should enable further improvements in the experimental precision.This article is part of the Theo Murphy meeting issue 'Antiproton physics in the ELENA era'. PMID- 29459411 TI - Collisions involving antiprotons and antihydrogen: an overview. AB - I give an overview of experimental and theoretical results for antiproton and antihydrogen scattering with atoms and molecules (in particular H, He). At low energies ([Formula: see text]1 keV) there are practically no experimental data available. Instead I compare the results from different theoretical calculations, of various degrees of sophistication. At energies up to a few tens of eV, I focus on simple approximations that give reasonably accurate results, as these allow quick estimates of collision rates without embarking on a research project.This article is part of the Theo Murphy meeting issue 'Antiproton physics in the ELENA era'. PMID- 29459412 TI - The ASACUSA antihydrogen and hydrogen program: results and prospects. AB - The goal of the ASACUSA-CUSP collaboration at the Antiproton Decelerator of CERN is to measure the ground-state hyperfine splitting of antihydrogen using an atomic spectroscopy beamline. A milestone was achieved in 2012 through the detection of 80 antihydrogen atoms 2.7 m away from their production region. This was the first observation of 'cold' antihydrogen in a magnetic field free region. In parallel to the progress on the antihydrogen production, the spectroscopy beamline was tested with a source of hydrogen. This led to a measurement at a relative precision of 2.7*10-9 which constitutes the most precise measurement of the hydrogen hyperfine splitting in a beam. Further measurements with an upgraded hydrogen apparatus are motivated by CPT and Lorentz violation tests in the framework of the Standard Model Extension. Unlike for hydrogen, the antihydrogen experiment is complicated by the difficulty of synthesizing enough cold antiatoms in the ground state. The first antihydrogen quantum states scan at the entrance of the spectroscopy apparatus was realized in 2016 and is presented here. The prospects for a ppm measurement are also discussed.This article is part of the Theo Murphy meeting issue 'Antiproton physics in the ELENA era'. PMID- 29459414 TI - Challenging the standard model by high-precision comparisons of the fundamental properties of protons and antiprotons. AB - The BASE collaboration investigates the fundamental properties of protons and antiprotons, such as charge-to-mass ratios and magnetic moments, using advanced cryogenic Penning trap systems. In recent years, we performed the most precise measurement of the magnetic moments of both the proton and the antiproton, and conducted the most precise comparison of the proton-to-antiproton charge-to-mass ratio. In addition, we have set the most stringent constraint on directly measured antiproton lifetime, based on a unique reservoir trap technique. Our matter/antimatter comparison experiments provide stringent tests of the fundamental charge-parity-time invariance, which is one of the fundamental symmetries of the standard model of particle physics. This article reviews the recent achievements of BASE and gives an outlook to our physics programme in the ELENA era.This article is part of the Theo Murphy meeting issue 'Antiproton physics in the ELENA era'. PMID- 29459415 TI - Prospects for comparison of matter and antimatter gravitation with ALPHA-g. AB - The ALPHA experiment has recently entered an expansion phase of its experimental programme, driven in part by the expected benefits of conducting experiments in the framework of the new AD + ELENA antiproton facility at CERN. With antihydrogen trapping now a routine operation in the ALPHA experiment, the collaboration is leading progress towards precision atomic measurements on trapped antihydrogen atoms, with the first excitation of the 1S-2S transition and the first measurement of the antihydrogen hyperfine spectrum (Ahmadi et al. 2017 Nature541, 506-510 (doi:10.1038/nature21040); Nature548, 66-69 (doi:10.1038/nature23446)). We are building on these successes to extend our physics programme to include a measurement of antimatter gravitation. We plan to expand a proof-of-principle method (Amole et al. 2013 Nat. Commun.4, 1785 (doi:10.1038/ncomms2787)), first demonstrated in the original ALPHA apparatus, and perform a precise measurement of antimatter gravitational acceleration with the aim of achieving a test of the weak equivalence principle at the 1% level. The design of this apparatus has drawn from a growing body of experience on the simulation and verification of antihydrogen orbits confined within magnetic minimum atom traps. The new experiment, ALPHA-g, will be an additional atom trapping apparatus located at the ALPHA experiment with the intention of measuring antihydrogen gravitation.This article is part of the Theo Murphy meeting issue 'Antiproton physics in the ELENA era'. PMID- 29459416 TI - The ELENA facility. AB - The CERN Antiproton Decelerator (AD) provides antiproton beams with a kinetic energy of 5.3 MeV to an active user community. The experiments would profit from a lower beam energy, but this extraction energy is the lowest one possible under good conditions with the given circumference of the AD. The Extra Low Energy Antiproton ring (ELENA) is a small synchrotron with a circumference a factor of 6 smaller than the AD to further decelerate antiprotons from the AD from 5.3 MeV to 100 keV. Controlled deceleration in a synchrotron equipped with an electron cooler to reduce emittances in all three planes will allow the existing AD experiments to increase substantially their antiproton capture efficiencies and render new experiments possible. ELENA ring commissioning is taking place at present and first beams to a new experiment installed in a new experimental area are foreseen in 2017. The transfer lines from ELENA to existing experiments in the old experimental area will be installed during CERN Long Shutdown 2 (LS2) in 2019 and 2020. The status of the project and ring commissioning will be reported.This article is part of the Theo Murphy meeting issue 'Antiproton physics in the ELENA era'. PMID- 29459413 TI - AEgIS at ELENA: outlook for physics with a pulsed cold antihydrogen beam. AB - The efficient production of cold antihydrogen atoms in particle traps at CERN's Antiproton Decelerator has opened up the possibility of performing direct measurements of the Earth's gravitational acceleration on purely antimatter bodies. The goal of the AEgIS collaboration is to measure the value of g for antimatter using a pulsed source of cold antihydrogen and a Moire deflectometer/Talbot-Lau interferometer. The same antihydrogen beam is also very well suited to measuring precisely the ground-state hyperfine splitting of the anti-atom. The antihydrogen formation mechanism chosen by AEgIS is resonant charge exchange between cold antiprotons and Rydberg positronium. A series of technical developments regarding positrons and positronium (Ps formation in a dedicated room-temperature target, spectroscopy of the n=1-3 and n=3-15 transitions in Ps, Ps formation in a target at 10 K inside the 1 T magnetic field of the experiment) as well as antiprotons (high-efficiency trapping of [Formula: see text], radial compression to sub-millimetre radii of mixed [Formula: see text] plasmas in 1 T field, high-efficiency transfer of [Formula: see text] to the antihydrogen production trap using an in-flight launch and recapture procedure) were successfully implemented. Two further critical steps that are germane mainly to charge exchange formation of antihydrogen-cooling of antiprotons and formation of a beam of antihydrogen-are being addressed in parallel. The coming of ELENA will allow, in the very near future, the number of trappable antiprotons to be increased by more than a factor of 50. For the antihydrogen production scheme chosen by AEgIS, this will be reflected in a corresponding increase of produced antihydrogen atoms, leading to a significant reduction of measurement times and providing a path towards high-precision measurements.This article is part of the Theo Murphy meeting issue 'Antiproton physics in the ELENA era'.

I first discuss which elements are desirable for any theory where the long-range interactions between matter and antimatter differ from those of matter with itself. Afterwards I describe the standard way to hide the effects of new forces in matter-matter interactions which still allows one to generate ponderable matter-antimatter interactions. Finally, I comment on some recent ideas and propose some possible future directions.This article is part of the Theo Murphy meeting issue 'Antiproton physics in the ELENA era'.

PMID- 29459421 TI - IGF-1 protects SH-SY5Y cells against MPP+-induced apoptosis via PI3K/PDK-1/Akt pathway. AB - Insulin-like growth factor (IGF)-1 is a well-known anti-apoptotic pro-survival factor and phosphatidylinositol-3-kinase (PI3K)/Akt pathway is linked to cell survival induced by IGF-1. It is also reported that Akt signaling is modulated by 3-phosphoinositide-dependent kinase-1 (PDK1). In the current study, we investigated whether the anti-apoptotic effect of IGF-1 in SH-SY5Y cells exposed to 1-methyl-4-phenylpyridinium (MPP+) is associated with the activity of PI3K/PDK1/Akt pathway. Treatment of cells with IGF-1 inhibited MPP+-induced apoptotic cell death. IGF-1-induced activation of Akt and the protective effect of IGF-1 on MPP+-induced apoptosis were abolished by chemical inhibition of PDK1 (GSK2334470) or PI3K (LY294002). The phosphorylated levels of Akt and PDK1 were significantly suppressed after MPP+ exposure, while IGF-1 treatment completely restored MPP+-induced reductions in phosphorylation. IGF-1 protected cells from MPP+ insult by suppressing intracellular reactive oxygen species (ROS) production and malondialdehyde levels and increasing superoxide dismutase activity. Mitochondrial ROS levels were also increased during MPP+ exposure, which were attenuated by IGF-1 treatment. In addition, IGF-1-treated cells showed increased activities of succinate dehydrogenase and citrate synthase, stabilization of mitochondrial transmembrane potential, increased ratio of Bcl-2 to Bax, prevention of cytochrome c release and inhibition of caspase-3 activation with PARP cleavage. Furthermore, the protective effects of IGF-1 on oxidative stress and mitochondrial dysfunction were attenuated when cells were preincubated with GSK2334470 or LY294002. Our data suggest that IGF-1 protects SH-SY5Y cells against MPP+-associated oxidative stress by preserving mitochondrial integrity and inhibiting mitochondrial apoptotic cascades via the activation of PI3K/PDK1/Akt pathway.

AB - BACKGROUND: This study was conducted to find out whether boys with constitutional delay in growth and puberty (CDGP) could attain their target height and predicted adult height (PAH) in adulthood or not. METHODS: After measuring the height, weight, pubertal stage, parental height and bone age data of the patients at their first presentation were extracted from the files and their height and weight were measured at the end of the study, wrist X-Ray was performed in order to determine the bone age. PAH was calculated using Bayley-Pinneau method and target height was estimated by mid parental height. Final or near final heights of the patients were measured and compared with the target height and PAH. RESULTS: The mean age at presentation and the end of study was 15.2 +/- 0.95, 20 +/- 0.75 years respectively. Mean of bone age at the beginning of study was 12.97 +/- 1 years and at the end of study were 17.6 +/- 0.58 years. Mean of delayed bone age was 2.2 +/- 0.82 years. Mean of the primary measured heights was 150.16 +/- 7 cm (138-160 cm). Mean of final or near final heights was 165.7 +/- 2.89 cm (161-170.5 cm). Final or near final heights in our subjects were smaller than either their PAH (165.7 +/- 2.89 vs 170.7 +/- 5.17) (P value <0.005) or target height (165.7 +/- 2.89 vs 171.8 +/- 4.65) (P value <0.0001). CONCLUSION: Most patients with CDGP do not reach their target height or predicted adult height; they are usually shorter than their parents and general population. Such patients need to be followed up until they reach their final height and, in some cases, adjunctive medical treatment might be indicated. PMID- 29459423 TI - Associations between LPL gene polymorphisms and coronary artery disease: evidence based on an updated and cumulative meta-analysis. AB - Lipoprotein lipase (LPL) is widely linked to lipid and lipoprotein metabolism, but its effects on coronary artery disease (CAD) are not clearly elucidated. The aim of this study was to clarify the association between LPL gene polymorphisms and CAD susceptibility. The pooled odds ratio (OR) and 95% confidence interval (CI) were calculated to estimate the strength of the relationship between LPL gene polymorphisms and CAD risk. Comprehensive electronic databases, including PubMed, EMBASE, Web of Science, and the Cochrane Library, were systematically searched. A total of 45 records containing 80 eligible studies were analyzed. The results indicated an increased risk between the LPL D9N polymorphism and susceptibility to CAD in the dominant genetic model (AA + GA vs. GG: OR = 1.46, 95% CI = 1.14-1.87), whereas the LPL HindIII polymorphism showed a protective effect against CAD under all tested models (GG+GT vs. TT: OR = 0.85, 95% CI = 0.75-0.97; GG vs. TT + TG: OR = 0.62, 95% CI = 0.47-0.83; G vs. T: OR = 0.81, 95% CI = 0.71-0.92). No significant association was identified for the LPL N291S and PvuII polymorphisms. Stratification analysis by ethnicity suggested a significant correlation between the LPL S447X polymorphism and CAD susceptibility in Caucasians under the dominant and allele genetic models. In summary, our meta analysis indicated that the LPL D9N polymorphism was associated with an increased risk of CAD, whereas the S447X and HindIII polymorphisms showed protective effects. There was no association observed between the N291S and PvuII polymorphisms and CAD risk. PMID- 29459424 TI - The role of adherens junction proteins in the regulation of insulin secretion. AB - In healthy individuals, any rise in blood glucose levels is rapidly countered by the release of insulin from the beta-cells of the pancreas which in turn promotes the uptake and storage of the glucose in peripheral tissues. The beta-cells possess exquisite mechanisms regulating the secretion of insulin to ensure that the correct amount of insulin is released. These mechanisms involve tight control of the movement of insulin containing secretory vesicles within the beta-cells, initially preventing most vesicles being able to move to the plasma membrane. Elevated glucose levels trigger an influx of Ca2+ that allows fusion of the small number of insulin containing vesicles that are pre-docked at the plasma membrane but glucose also stimulates processes that allow other insulin containing vesicles located further in the cell to move to and fuse with the plasma membrane. The mechanisms controlling these processes are complex and not fully understood but it is clear that the interaction of the beta-cells with other beta cells in the islets is very important for their ability to develop the appropriate machinery for proper regulation of insulin secretion. Emerging evidence indicates one factor that is key for this is the formation of homotypic cadherin mediated adherens junctions between beta-cells. Here, we review the evidence for this and discuss the mechanisms by which these adherens junctions might regulate insulin vesicle trafficking as well as the implications this has for understanding the dysregulation of insulin secretion seen in pathogenic states. PMID- 29459425 TI - Inositol Pyrophosphate Synthesis by Diphosphoinositol Pentakisphosphate Kinase-1 is Regulated by Phosphatidylinositol(4,5)bisphosphate. AB - 5-diphosphoinositol tetrakisphosphate (5-InsP7) and bisdiphosphoinositol tetrakisphosphate (InsP8) are 'energetic' inositol pyrophosphate signaling molecules that regulate bioenergetic homeostasis. Inositol pyrophosphate levels are regulated by diphosphoinositol pentakisphosphate kinases (PPIP5Ks); these are large modular proteins that host a kinase domain (which phosphorylates 5-InsP7 to InsP8), a phosphatase domain that catalyzes the reverse reaction, and a polyphosphoinositide-binding domain (PBD). Here, we describe new interactions between these three domains in the context of full-length human PPIP5K1. We determine that InsP7 kinase activity is dominant when PPIP5K1 is expressed in intact cells; in contrast, we found that InsP8 phosphatase activity prevails when the enzyme is isolated from its cellular environment. We approach a reconciliation of this disparity by showing that cellular InsP8 phosphatase activity is inhibited by C8-PtdIns(4,5)P2 (IC50 approx. 40 iM). We recapitulate this phosphatase inhibition with natural PtdIns(4,5)P2 that was incorporated into large unilamellar vesicles. Additionally, PtdIns(4,5)P2 increases net InsP7 kinase activity 5-fold. We oftlinedemonstrate that PtdIns(4,5)P2 is not itself a phosphatase substrate; its inhibition of InsP8 phosphatase activity results from an unusual, functional overlap between the phosphatase domain and the PBD. Finally, we discuss the significance of PtdIns(4,5)P2 as a novel regulator of PPIP5K1, in relation to compartmentalization of InsP7/InsP8 signaling in vivo.

AB - The aim of the present study was to identify abdominal aortic aneurysms (AAA) associated miR-155 contributing to AAA pathology by regulating macrophage mediated inflammation. Angiotensin II (AngII)-infused apolipoprotein E-deficient (ApoE-/-) mice and THP-1 cells model of miR-155 overexpression and deficiency were used in the experiments. The expression of miR-155 was detected by quantitative reverse transcription polymerase chain reaction (qRT-PCR). Cytokines were evaluated using enzyme-linked immunoabsorbent assay (ELISA). Western blotting was used to measure the levels of MMP-2, MMP-9, iNOS, and monocyte chemoattractant protein (MCP)-1 proteins. Immunostaining and transwell were used to determine CD68, elastic collagen, proliferation, and migration of vascular smooth muscle cells (VSMCs). The results showed that miR-155 and cytokines were up-regulated in AAA patients or ApoE-/- mice. Overexpression of miR-155 enhanced MMP-2, MMP-9, iNOS, and MCP-1 levels, and stimulated the proliferation and migration of VSMCs. Meanwhile, inhibition of miR-155 had the opposite effect. In addition, histology demonstrated accumulation of CD68 and elastic collagen positive areas significantly decreased in miR-155 antagomir injection group. In conclusion, the results of the present study suggest that inhibiting miR-155 is crucial to prevent the development of AAA by regulating macrophage inflammation. PMID- 29459428 TI - Attenuation of NK cells facilitates mammary tumor growth in streptozotocin induced diabetes in mice. AB - Diabetic patients have higher incidence and mortality of cancer. Recent study revealed that hyperglycemia-induced oxidative stress is involved in the acceleration of tumor metastasis. We used model of high-dose streptozotocin induced diabetes to investigate its effect on tumor growth and modulation of antitumor immune response of 4T1 murine breast cancer in BALB/c mice. Diabetes accelerated tumor appearance, growth and weight, which was associated with decreased NK cells cytotoxicity against 4T1 tumor cells in vitro Diabetes reduced frequencies of systemic NKG2D+, perforin+, granzyme+, IFN-gamma+ and IL-17+ NK cells, while increased level of PD-1 expression and production of IL-10 in NK cells. Diabetes decreased percentage of NKG2D+NK cells and increased percentage of PD-1+ NK cells also in primary tumor. Diabetes increased accumulation of IL 10+ Tregs and TGF-beta+ myeloid-derived suppressor cells (MDSCs) in spleen and tumor. Diabetic sera in vitro significantly increased the percentage of KLRG-1+ and PD-1+ NK cells, decreased the percentage of IFN-gamma+NK cells, expression of NKp46 and production of perforin, granzyme, CD107a and IL-17 per NK cell in comparison to glucose-added mouse sera and control sera. Significantly increased percentages of inducible nitric oxide synthase (iNOS) and indoleamine 2,3 dioxygenase (IDO) producing MDSCs and dendritic cells (DC) were found in the spleens of diabetic mice prior to tumor induction. 1-methyl-DL-tryptophan, specific IDO inhibitor, almost completely restored phenotype of NK cells cultivated in diabetic sera. These findings indicate that diabetes promotes breast cancer growth at least in part through increased accumulation of immunosuppressive cells and IDO-mediated attenuation of NK cells. PMID- 29459429 TI - 14-year case series of eyelid sebaceous gland carcinoma in Chinese patients and review of management. AB - AIMS: Sebaceous gland carcinoma (SGC) of the eyelid is a rare but potentially deadly cancer. The purpose of this study was to determine whether the American Joint Committee on Cancer (AJCC) 7th Edition T category for SGC correlated with metastasis and survival in the Chinese population. METHODS: This was a retrospective, single-centre cohort study. Patients with surgically resected eyelid SGC between January 2001 and May 2015 at the Hong Kong Eye Hospital were reviewed. Tumours were staged using the AJCC criteria. The main outcome measures included local recurrence, metastasis and death. Disease-free survival (DFS) was measured from the completion of treatment; overall survival was measured from the date of initial diagnosis. RESULTS: The study included 22 Chinese patients with a mean age of 65.4 years. The majority presented as a nodular lesion (91%) with 12 eyes (54.5%) initially misdiagnosed and a mean presentation time of 1 year. It was found that those with AJCC stage T2b or higher were significantly associated with lymph node metastasis (P=0.002) when compared with those with stage T2a. Older age at diagnosis (P=0.035) and no misdiagnosis (P=0.025) were associated with shorter DFS. Those with stage 3a or higher were associated with shorter DFS (P=0.007) and overall survival (P=0.024). CONCLUSION: Similar to previous reports, in this Chinese cohort, AJCC staging for SGC correlated with lymph node metastasis, DFS and overall survival. Those with stage 2b or higher on presentation will need closer surveillance for lymph node metastasis and may benefit from sentinel lymph node biopsy. PMID- 29459430 TI - Adalimumab for the treatment of refractory active and inactive non-infectious uveitis. AB - BACKGROUND/AIMS: To compare the efficacy of adalimumab in eyes with active and inactive non-infectious uveitis in the real-world setting. METHODS: Multicentre, retrospective, chart review of patients with refractory non-infectious uveitis treated with adalimumab. Main outcome measures included reduction of prednisolone dose, ability to taper immunosuppressives and a composite endpoint of treatment failure encompassing active inflammatory chorioretinal or retinal vascular lesions, intraocular inflammation grade and visual acuity. RESULTS: Thirty-seven eyes of 22 patients were studied. Mean follow-up was 20.1 months (median: 13). Most had either posterior or panuveitis (n=12, 55%). Mean duration of uveitis at baseline was 83.2 months (median: 61), where the majority (n=15, 68%) had already been treated with two or more conventional immunosuppressive agents in addition to prednisolone. Oral prednisolone was reduced to <=10 mg/day in 9 of 12 patients (75%) by 6 weeks. At 6 months of therapy, nine (90%) of the active eyes achieved a 2-step improvement in anterior chamber inflammation, with six (60%) demonstrating a similar improvement in vitreous haze grade. Almost all (n=17, 94%) of the initially inactive eyes maintained clinical quiescence at this time point. The incidence rate of treatment failure during follow-up was 88 per 100 eye-years for the active eyes and 24 per 100 eye-years for the initially inactive eyes. There were no serious adverse effects. CONCLUSION: Adalimumab appears to reduce the corticosteroid burden in active and inactive non-infectious uveitis in the real-world setting. Inflammatory activity at the time of adalimumab commencement may determine long-term treatment success. PMID- 29459431 TI - Comparative activity of antimicrobials against Pseudomonas aeruginosa, Achromobacter xylosoxidans and Stenotrophomonas maltophilia keratitis isolates. AB - BACKGROUND/AIMS: Achromobacter xylosoxidans and Stenotrophomonas maltophilia are emerging corneal pathogens, which are closely related to Pseudomonas aeruginosa, and have intrinsic resistance to many commonly available antimicrobials. The purpose of this study is to compare the in vitro efficacy of 12 antimicrobial agents against A. xylosoxidans, S. maltophilia and P. aeruginosa isolates recovered from clinical cases of keratitis. METHODS: Recovered corneal isolates (n=58) were identified and extracted from the Microbiology Data Bank of the Bascom Palmer Eye Institute. Comparative in vitro minimum inhibitory concentration (MIC) susceptibility profiles for fluoroquinolones, aminoglycosides, beta-lactams and miscellaneous antibiotics were recorded using the E-test methodology. Pharmacodynamic indices (Cmax/MIC) were calculated. RESULTS: A. xylosoxidans and S. maltophilia isolates were resistant to fluoroquinolones, aminoglycosides and ceftazidime (susceptibility rate ranging from 0% to 30%) while P. aeruginosa isolates showed a susceptibility rate of 95% 100% to these antimicrobials (P<0.00001 for the various antimicrobials). Exception was moxifloxacin with 80% of susceptibility rate to S. maltophilia isolates and Cmax/MIC=10.19. Ninety to 100% susceptibility rates were found for minocycline and trimethoprim/sulfamethoxazole for both A. xylosoxidans and S. maltophilia. One hundred per cent of the A. xylosoxidans isolates were susceptible to piperacillin/tazobactam and ticarcillin/clavulanic acid. CONCLUSIONS: There is a significant difference in susceptibility patterns between A. xylosoxidans, S. maltophilia and P. aeruginosa. Fluoroquinolones and aminoglycosides may not be effective against A. xylosoxidans and S. maltophilia. Antibiotics that are not commercially available as eye drops, such as beta lactams for A. xylosoxidans, and trimethoprim/sulfamethoxazole and minocycline for both A. xylosoxidans and S. maltophilia should be considered. PMID- 29459433 TI - Glaucoma awareness Indian military personnel: a tri-service study. AB - INTRODUCTION: In India, glaucoma is the third most common cause of blindness, reflecting both its asymptomatic presentation and a lack of knowledge in the general population. No previous published data of glaucoma awareness among the Indian Armed forces personnel exists, who constitute a unique group consisting of people drawn from all parts of the country and society. METHODS: Bilingual questionnaires were distributed to 496 serving Army, Navy and Air Force personnel serving in units local to the Zonal military hospital in North India. Having heard of the term glaucoma resulted in the subject being 'glaucoma aware', while 'knowledge of glaucoma' required at least three out of six questions to be answered correctly. RESULTS: 110/496 (22%) participants were found to be glaucoma aware, while knowledge of glaucoma was found in 60/496 (12%) participants. CONCLUSIONS: This study demonstrates that glaucoma awareness and knowledge is high compared with rural or urban Indian populations. This is likely reflects the frequent health camps conducted by the armed forces and periodic medical examinations. However, these figures are still low compared with developed countries and likely reflects differences in education standards, socioeconomic status and differing influences of the media. PMID- 29459434 TI - 'Inconguous'. PMID- 29459435 TI - Membrane cholesterol depletion as a trigger of Nav1.9 channel-mediated inflammatory pain. AB - Cholesterol is a major lipid component of the mammalian plasma membrane. While much is known about its metabolism, its transport, and its role in atherosclerotic vascular disease, less is known about its role in neuronal pathophysiology. This study reveals an unexpected function of cholesterol in controlling pain transmission. We show that inflammation lowers cholesterol content in skin tissue and sensory DRG culture. Pharmacological depletion of cellular cholesterol entails sensitization of nociceptive neurons and promotes mechanical and thermal hyperalgesia through the activation of voltage-gated Nav1.9 channels. Inflammatory mediators enhance the production of reactive oxygen species and induce partitioning of Nav1.9 channels from cholesterol-rich lipid rafts to cholesterol-poor non-raft regions of the membrane. Low-cholesterol environment enhances voltage-dependent activation of Nav1.9 channels leading to enhanced neuronal excitability, whereas cholesterol replenishment reversed these effects. Consistently, we show that transcutaneous delivery of cholesterol alleviates hypersensitivity in animal models of acute and chronic inflammatory pain. In conclusion, our data establish that membrane cholesterol is a modulator of pain transmission and shed a new light on the relationship between cholesterol homeostasis, inflammation, and pain.

AB - Final maturation of eukaryotic ribosomes occurs in the cytoplasm and requires the sequential removal of associated assembly factors and processing of the immature 20S pre-RNA Using cryo-electron microscopy (cryo-EM), we have determined the structure of a yeast cytoplasmic pre-40S particle in complex with Enp1, Ltv1, Rio2, Tsr1, and Pno1 assembly factors poised to initiate final maturation. The structure reveals that the pre-rRNA adopts a highly distorted conformation of its 3' major and 3' minor domains stabilized by the binding of the assembly factors. This observation is consistent with a mechanism that involves concerted release of the assembly factors orchestrated by the folding of the rRNA in the head of the pre-40S subunit during the final stages of maturation. Our results provide a structural framework for the coordination of the final maturation events that drive a pre-40S particle toward the mature form capable of engaging in translation.

Data on the related drug enzalutamide, also presented at the symposium, showed that that drug led to dramatic improvements in metastasis-free survival, too. PMID- 29459440 TI - Correction: ROS1-1. PMID- 29459437 TI - LPS targets host guanylate-binding proteins to the bacterial outer membrane for non-canonical inflammasome activation. AB - Pathogenic and commensal Gram-negative bacteria produce and release outer membrane vesicles (OMVs), which present several surface antigens and play an important role for bacterial pathogenesis. OMVs also modulate the host immune system, which makes them attractive as vaccine candidates. At the cellular level, OMVs are internalized by macrophages and deliver lipopolysaccharide (LPS) into the host cytosol, thus activating the caspase-11 non-canonical inflammasome. Here, we show that OMV-induced inflammasome activation requires TLR4-TRIF signaling, the production of type I interferons, and the action of guanylate binding proteins (GBPs), both in macrophages and in vivo Mechanistically, we find that isoprenylated GBPs associate with the surface of OMVs or with transfected LPS, indicating that the key factor that determines GBP recruitment to the Gram negative bacterial outer membranes is LPS itself. Our findings provide new insights into the mechanism by which GBPs target foreign surfaces and reveal a novel function for GBPs in controlling the intracellular detection of LPS derived from extracellular bacteria in the form of OMVs, thus extending their function as a hub between cell-autonomous immunity and innate immunity.

AB - Death receptor 6 (DR6) is an orphan member of the TNF receptor superfamily and controls cell death and differentiation in a cell-autonomous manner in different cell types. Here, we report an additional non-cell-autonomous function for DR6 in the peripheral nervous system (PNS). DR6-knockout (DR6 KO) mice showed precocious myelination in the PNS Using an in vitro myelination assay, we demonstrate that neuronal DR6 acts in trans on Schwann cells (SCs) and reduces SC proliferation and myelination independently of its cytoplasmic death domain. Mechanistically, DR6 was found to be cleaved in neurons by "a disintegrin and metalloprotease 10" (ADAM10), releasing the soluble DR6 ectodomain (sDR6). Notably, in the in vitro myelination assay, sDR6 was sufficient to rescue the DR6 KO phenotype. Thus, in addition to the cell-autonomous receptor function of full-length DR6, the proteolytically released sDR6 can unexpectedly also act as a paracrine signaling factor in the PNS in a non-cell-autonomous manner during SC proliferation and myelination. This new mode of DR6 signaling will be relevant in future attempts to target DR6 in disease settings.

AB - Growth hormone (GH) is produced primarily by anterior pituitary somatotroph cells. Numerous acute human (h) GH treatment and long-term follow-up studies and extensive use of animal models of GH action have shaped the body of GH research over the past 70 years. Work on the GH receptor (R)-knockout (GHRKO) mice and results of studies on GH-resistant Laron Syndrome (LS) patients have helped define many physiological actions of GH including those dealing with metabolism, obesity, cancer, diabetes, cognition and aging/longevity. In this review, we have discussed several issues dealing with these biological effects of GH and attempt to answer the question of whether decreased GH action may be beneficial.

AB - Purpose: Levels of endoxifen, the most active metabolite of tamoxifen, vary by the highly polymorphic cytochrome P450 (CYP) 2D6 enzyme. We prospectively investigated tamoxifen efficacy by serum endoxifen levels and the tamoxifen activity score (TAS).Experimental Design: A prospective observational multicenter study included postmenopausal women with an estrogen receptor-positive breast cancer receiving first-line tamoxifen, 20 mg daily in the neoadjuvant or metastatic setting, recruited between February 2009 and May 2014. The primary endpoint was the objective response rate (ORR) using RECIST criteria 1.0. Secondary endpoints were clinical benefit (CB), progression-free survival (PFS), and tolerability of tamoxifen. The main analysis used logistic regression to relate ORR to serum endoxifen levels after 3 months. Endpoints were also related to other tamoxifen metabolites and to TAS.Results: Endoxifen levels were available for 247 of all 297 patients (83%), of which 209 with target lesions (85%). Median follow-up time for PFS was 32.5 months, and 62% progressed. ORR and CB were 45% and 84%, respectively. ORR was not related to endoxifen, and the OR of ORR was 1.008 per MUg/L increase in endoxifen (95% confidence interval, 0.971 1.046; P = 0.56). In general, none of the endpoints was associated with endoxifen levels, tamoxifen metabolites, or TAS.Conclusions: Under the prespecified assumptions, the results from this prospective clinical trial do not suggest therapeutic drug monitoring of endoxifen to be of clinical value in postmenopausal women treated with tamoxifen for breast cancer in the neoadjuvant or metastatic setting.

PMID- 29459463 TI - Sex Differences in the Presentation and Perception of Symptoms Among Young Patients With Myocardial Infarction: Evidence from the VIRGO Study (Variation in Recovery: Role of Gender on Outcomes of Young AMI Patients). AB - BACKGROUND: Some studies report that women are less likely to present with chest pain for acute myocardial infarction (AMI). Information on symptom presentation, perception of symptoms, and care-seeking behaviors is limited for young patients with AMI. METHODS: We interviewed 2009 women and 976 men aged 18 to 55 years hospitalized for AMI at 103 US hospitals participating in the VIRGO study (Variation in Recovery: Role of Gender on Outcomes of Young AMI Patients). Structured patient interviews during the index AMI hospitalization were used to collect information on symptom presentation, perception of symptoms, and care seeking behaviors. We compared patient characteristics and presentation information by sex. Multivariable hierarchical logistic regression was used to evaluate the association between sex and symptom presentation. RESULTS: The majority of women (87.0%) and men (89.5%) presented with chest pain (defined as pain, pressure, tightness, or discomfort). Women were more likely to present with >=3 associated symptoms than men (eg, epigastric symptoms, palpitations, and pain or discomfort in the jaw, neck, arms, or between the shoulder blades; 61.9% for women versus 54.8% for men, P<0.001). In adjusted analyses, women with an ST segment-elevation AMI were more likely than men to present without chest pain (odds ratio, 1.51; 95% confidence interval, 1.03-2.22). In comparison with men, women were more likely to perceive symptoms as stress/anxiety (20.9% versus 11.8%, P<0.001) but less likely to attribute symptoms to muscle pain (15.4% versus 21.2%, P=0.029). Approximately 29.5% of women and 22.1% of men sought medical care for similar symptoms before their hospitalization (P<0.001); however, 53% of women reported that their provider did not think these symptoms were heart-related in comparison with 37% of men (P<0.001). CONCLUSIONS: The presentation of AMI symptoms was similar for young women and men, with chest pain as the predominant symptom for both sexes. Women presented with a greater number of additional non-chest pain symptoms regardless of the presence of chest pain, and both women and their healthcare providers were less likely to attribute their prodromal symptoms to heart disease in comparison with men. PMID- 29459462 TI - Sex Difference in Patients With Ischemic Heart Failure Undergoing Surgical Revascularization: Results From the STICH Trial (Surgical Treatment for Ischemic Heart Failure). AB - BACKGROUND: Female sex is conventionally considered a risk factor for coronary artery bypass grafting (CABG) and has been included as a poor prognostic factor in multiple cardiac operative risk evaluation scores. We aimed to investigate the association of sex and the long-term benefit of CABG in patients with ischemic left ventricular dysfunction enrolled in the prospective STICH trial (Surgical Treatment for Ischemic Heart Failure Study). METHODS: The STICH trial randomized 1212 patients (148 [12%] women and 1064 [88%] men) with coronary artery disease and left ventricular ejection fraction <=35% to CABG+medical therapy (MED) versus MED alone. Long-term (10-year) outcomes with each treatment were compared according to sex. RESULTS: At baseline, women were older (63.4 versus 59.3 years; P=0.016) with higher body mass index (27.9 versus 26.7 kg/m2; P=0.001). Women had more coronary artery disease risk factors (diabetes mellitus, 55.4% versus 37.2%; hypertension, 70.9% versus 58.6%; hyperlipidemia, 70.3% versus 58.9%) except for smoking (13.5% versus 21.8%) and had lower rates of prior CABG (0% versus 3.4%; all P<0.05) than men. Moreover, women had higher New York Heart Association class (class III/IV, 66.2% versus 57.0%), lower 6-minute walk capacity (300 versus 350 m), and lower Kansas City Cardiomyopathy Questionnaire overall summary scores (51 versus 63; all P<0.05). Over 10 years of follow-up, all-cause mortality (49.0% versus 65.8%; adjusted hazard ratio, 0.67; 95% confidence interval, 0.52-0.86; P=0.002) and cardiovascular mortality (34.3% versus 52.3%; adjusted hazard ratio, 0.65; 95% confidence interval, 0.48-0.89; P=0.006) were significantly lower in women compared with men. With randomization to CABG+MED versus MED treatment, there was no significant interaction between sex and treatment group in all-cause mortality, cardiovascular mortality, or the composite of all-cause mortality or cardiovascular hospitalization (all P>0.05). In addition, surgical deaths were not statistically different (1.5% versus 5.1%; P=0.187) between sexes among patients randomized to CABG per protocol as initial treatment. CONCLUSIONS: Sex is not associated with the effect of CABG+MED versus MED on all-cause mortality, cardiovascular mortality, the composite of death or cardiovascular hospitalization, or surgical deaths in patients with ischemic left ventricular dysfunction. Thus, sex should not influence treatment decisions about CABG in these patients. CLINICAL TRIAL REGISTRATION: URL: https://www.clinicaltrials.gov. Unique identifier: NCT00023595. PMID- 29459466 TI - Pregnancy Outcomes in Women With Rheumatic Mitral Valve Disease: Results From the Registry of Pregnancy and Cardiac Disease. AB - BACKGROUND: Cardiac disease is 1 of the major causes of maternal mortality. We studied pregnancy outcomes in women with rheumatic mitral valve disease. METHODS: The Registry of Pregnancy and Cardiac Disease is an international prospective registry, and consecutive pregnant women with cardiac disease were included. Pregnancy outcomes in all women with rheumatic mitral valve disease and no prepregnancy valve replacement is described in the present study (n=390). A maternal cardiac event was defined as cardiac death, arrhythmia requiring treatment, heart failure, thromboembolic event, aortic dissection, endocarditis, acute coronary syndrome, and hospitalization for other cardiac reasons or cardiac intervention. Associations between patient characteristics and cardiac outcomes were checked in a 3-level model (patient-center-country). RESULTS: Most patients came from emerging countries (75%). Mitral stenosis (MS) with or without mitral regurgitation (MR) was present in 273 women, isolated MR in 117. The degree of MS was mild in 20.9%, moderate in 39.2%, severe in 19.8%, and severity not classified in the remainder. Maternal death during pregnancy occurred in 1 patient with severe MS. Hospital admission occurred in 23.1% of the women with MS, and the main reason was heart failure (mild MS 15.8%, moderate 23.4%, severe 48.1%; P<0.001). Heart failure occurred in 23.1% of patients with moderate or severe MR. An intervention during pregnancy was performed in 16 patients, 14 had percutaneous balloon mitral commissurotomy, and 2 had surgical valve replacement (1 for MS, 1 for MR). In multivariable modeling, prepregnancy New York Heart Association class >1 was an independent predictor of maternal cardiac events. Follow-up at 6 months postpartum was available for 53%, and 3 more patients died (1 with severe MS, 1 with moderate MS, 1 with moderate to severe MR). CONCLUSIONS: Although mortality was only 1.9% during pregnancy, ~50% of the patients with severe rheumatic MS and 23% of those with significant MR developed heart failure during pregnancy. Prepregnancy counseling and considering mitral valve interventions in selected patients are important to prevent these complications. PMID- 29459465 TI - Mental Stress-Induced-Myocardial Ischemia in Young Patients With Recent Myocardial Infarction: Sex Differences and Mechanisms. AB - BACKGROUND: Mental stress-induced myocardial ischemia (MSIMI) is frequent in patients with coronary artery disease and is associated with worse prognosis. Young women with a previous myocardial infarction (MI), a group with unexplained higher mortality than men of comparable age, have shown elevated rates of MSIMI, but the mechanisms are unknown. METHODS: We studied 306 patients (150 women and 156 men) <=61 years of age who were hospitalized for MI in the previous 8 months and 112 community controls (58 women and 54 men) frequency matched for sex and age to the patients with MI. Endothelium-dependent flow-mediated dilation and microvascular reactivity (reactive hyperemia index) were measured at rest and 30 minutes after mental stress. The digital vasomotor response to mental stress was assessed using peripheral arterial tonometry. Patients received 99mTc-sestamibi myocardial perfusion imaging at rest, with mental (speech task) and conventional (exercise/pharmacological) stress. RESULTS: The mean age of the sample was 50 years (range, 22-61). In the MI group but not among controls, women had a more adverse socioeconomic and psychosocial profile than men. There were no sex differences in cardiovascular risk factors, and among patients with MI, clinical severity tended to be lower in women. Women in both groups showed a higher peripheral arterial tonometry ratio during mental stress but a lower reactive hyperemia index after mental stress, indicating enhanced microvascular dysfunction after stress. There were no sex differences in flow-mediated dilation changes with mental stress. The rate of MSIMI was twice as high in women as in men (22% versus 11%, P=0.009), and ischemia with conventional stress was similarly elevated (31% versus 16%, P=0.002). Psychosocial and clinical risk factors did not explain sex differences in inducible ischemia. Although vascular responses to mental stress (peripheral arterial tonometry ratio and reactive hyperemia index) also did not explain sex differences in MSIMI, they were predictive of MSIMI in women only. CONCLUSIONS: Young women after MI have a 2 fold likelihood of developing MSIMI compared with men and a similar increase in conventional stress ischemia. Microvascular dysfunction and peripheral vasoconstriction with mental stress are implicated in MSIMI among women but not among men, perhaps reflecting women's proclivity toward ischemia because of microcirculatory abnormalities.

PMID- 29459468 TI - Genetics, Lifestyle, and Low-Density Lipoprotein Cholesterol in Young and Apparently Healthy Women. AB - BACKGROUND: Atherosclerosis starts in childhood but low-density lipoprotein cholesterol (LDL-C), a causal risk factor, is mostly studied and dealt with when clinical events have occurred. Women are usually affected later in life than men and are underdiagnosed, undertreated, and understudied in cardiovascular trials and research. This study aims at a better understanding of lifestyle and genetic factors that affect LDL-C in young women. METHODS: We randomly selected for every year of age 8 women with LDL-C <=1st percentile (<=50 mg/dL) and 8 women with LDL C >=99th percentile (>=186 mg/dL) from 28 000 female participants aged between 25 to 40 years of a population-based cohort study. The resulting groups include 119 and 121 women, respectively, of an average 33 years of age. A gene-sequencing panel was used to assess established monogenic and polygenic origins of these phenotypes. Information on lifestyle was extracted from questionnaires. A healthy lifestyle score was allocated based on a recently developed algorithm. RESULTS: Of the women with LDL-C <=1st percentile, 19 (15.7%) carried mutations that are causing monogenic hypocholesterolemia and 60 (49.6%) were genetically predisposed to low LDL-C on the basis of an extremely low weighted genetic risk score. In comparison with control groups, a healthier lifestyle was not associated with low LDL-C in women without genetic predispositions. Among women with LDL-C >=99th percentile, 20 women (16.8%) carried mutations that cause familial hypercholesterolemia, whereas 25 (21%) were predisposed to high LDL-C on the basis of a high-weighted genetic risk score. The women in whom no genetic origin for hypercholesterolemia could be identified were found to exhibit a significantly unfavorable lifestyle in comparison with controls. CONCLUSIONS: This study highlights the need for early assessment of the cardiovascular risk profile in apparently healthy young women to identify those with LDL-C >=99th percentile for their age: first, because, in this study, 17% of the cases were molecularly diagnosed with familial hypercholesterolemia, which needs further attention; second, because our data indicate that an unfavorable lifestyle is significantly associated with severe hypercholesterolemia in genetically unaffected women, which may also need further attention. PMID- 29459469 TI - Female Sex Is a Risk Modifier Rather Than a Risk Factor for Stroke in Atrial Fibrillation: Should We Use a CHA2DS2-VA Score Rather Than CHA2DS2-VASc? AB - BACKGROUND: Stroke risk in atrial fibrillation is assessed by using the CHA2DS2 VASc score. Sex category (Sc, ie, female sex) confers 1 point on CHA2DS2-VASc. We hypothesized that female sex is a stroke risk modifier, rather than an overall risk factor, when added to a CHA2DS2-VA (sex-independent thromboembolism risk) score scale. METHODS: Using 3 nationwide registries, we identified patients with incident nonvalvular atrial fibrillation from January 1, 1997, through December 31, 2015. Patients receiving oral anticoagulant treatment at baseline were excluded, and person-time was censored at the time of treatment initiation (if any). CHA2DS2-VA scores were calculated for men and women, and were followed for up to 1 year in the Danish National Patient Registry. The primary outcome was a primary hospital code for ischemic stroke or systemic embolism (thromboembolism). We calculated crude event rates for risk strata as events per 100 person-years. For quantifying absolute risk of stroke, we calculated risks based on the pseudovalue method. Female sex as a prognostic factor was investigated by inclusion as an interaction term on the CHA2DS2-VA score to calculate the thromboembolic risk ratio for different score points. RESULTS: A total of 239 671 patients with atrial fibrillation (48.7% women) contributed to the analyses. The mean ages for women and men were 76.6 years and 70.3 years, respectively; the mean CHA2DS2-VA scores were 2.7 for women and 2.3 for men. The overall 1-year thromboembolic rate per 100 person-years for women was 7.3 and 5.7 for men. The 1 year absolute risk of thromboembolism was 0.5% among men and women with a CHA2DS2 VA score of 0 and increased up to >7% among very comorbid patients (score >5). The risk ratio (male as reference) across points >1 indicated that women exhibit a higher stroke risk. The interaction was statistically significant (P<0.001). CONCLUSIONS: Female sex is a risk modifier for stroke in patients with atrial fibrillation. Initial decisions on oral anticoagulant treatment could be guided by a CHA2DS2-VA score (ie, excluding the sex category criterion), but the Sc risk component modifies and accentuates stroke risk in women who would have been eligible for oral anticoagulant treatment on the basis of >=2 additional stroke risk factors. PMID- 29459470 TI - Metabolic Predictors of Incident Coronary Heart Disease in Women. AB - BACKGROUND: Although metabolomic profiling offers promise for the prediction of coronary heart disease (CHD), and metabolic risk factors are more strongly associated with CHD in women than men, limited data are available for women. METHODS: We applied a liquid chromatography-tandem mass spectrometry metabolomics platform to measure 371 metabolites in a discovery set of postmenopausal women (472 incident CHD cases, 472 controls) with validation in an independent set of postmenopausal women (312 incident CHD cases, 315 controls). RESULTS: Eight metabolites, primarily oxidized lipids, were significantly dysregulated in cases after the adjustment for matching and CHD risk factors in both the discovery and validation data sets. One oxidized phospholipid, C34:2 hydroxy phosphatidylcholine, remained associated with CHD after further adjustment for other validated metabolites. Subjects with C34:2 hydroxy-phosphatidylcholine levels in the highest quartile had a 4.7-fold increase in CHD odds in comparison with the lowest quartile; C34:2 hydroxy-phosphatidylcholine also significantly improved the area under the curve (P<0.01) for CHD. The C34:2 hydroxy phosphatidylcholine findings were replicated in a third replication data set of 980 men and women (230 cardiovascular events) with a stronger association observed in women. CONCLUSIONS: These data replicate known metabolite predictors, identify novel markers, and support the relationship between lipid oxidation and subsequent CHD. PMID- 29459471 TI - Gender/Sex as a Social Determinant of Cardiovascular Risk. AB - The social gradient for cardiovascular disease (CVD) onset and outcomes is well established. The American Heart Association's Social Determinants of Risk and Outcomes of Cardiovascular Disease Scientific Statement advocates looking beyond breakthroughs in biological science toward a social determinants approach that focuses on socioeconomic position, race and ethnicity, social support, culture and access to medical care, and residential environments to curb the burden of CVD going forward. Indeed, the benefits of this approach are likely to be far reaching, enhancing the positive effects of advances in CVD related to prevention and treatment while reducing health inequities that contribute to CVD onset and outcomes. It is disappointing that the role of gender has been largely neglected despite being a critical determinant of cardiovascular health. It is clear that trajectories and outcomes of CVD differ by biological sex, yet the tendency for sex and gender to be conflated has contributed to the idea that both are constant or fixed with little room for intervention. Rather, as distinct from biological sex, gender is socially produced. Overlaid on biological sex, gender is a broad term that shapes and interacts with one's cognition to guide norms, roles, behaviors, and social relations. It is a fluid construct that varies across time, place, and life stage. Gender can interact with biological sex and, indeed, other social determinants, such as ethnicity and socioeconomic position, to shape cardiovascular health from conception, through early life when health behaviors and risk factors are shaped, into adolescence and adulthood. This article will illustrate how gender shapes the early adoption of health behaviors in childhood, adolescence, and young adulthood by focusing on physical activity, drinking, and smoking behaviors (including the influence of role modeling). We will also discuss the role of gender in psychosocial stress with a focus on trauma from life events (childhood assault and intimate partner violence) and work, home, and financial stresses. We conclude by exploring potential biological pathways, with a focus on autonomic functioning, which may underpin gender as a social determinant of cardiovascular health. Finally, we discuss implications for cardiovascular treatment and awareness campaigns and consider whether gender equality strategies could reduce the burden of CVD for men and women at the population level. PMID- 29459473 TI - Women Not Receiving Optimal Preventive Medications. PMID- 29459472 TI - Association of Spontaneous Preterm Delivery and Future Maternal Cardiovascular Disease. AB - Cardiovascular disease (CVD) risk factors are well established. However, little is known about a woman's cardiovascular response to pregnancy, which appears to be an early marker of future maternal CVD risk. Spontaneous preterm delivery (sPTD) has been associated with a <=3-fold increased risk of maternal CVD death later in life compared with having a term delivery. This review focuses on 3 key areas to critically assess the association of sPTD and future maternal CVD risk: (1) CVD risk factors, (2) inflammatory biomarkers of interest, and (3) specific forms of vascular dysfunction, such as endothelial function and arterial stiffness, and mechanisms by which each may be linked to sPTD. The association of sPTD with subsequent future maternal CVD risk suggests that a woman's abnormal response to pregnancy may serve as her first physiological stress test. These findings suggest that future research is needed to understand why women with sPTD may be at risk for CVD to implement effective interventions earlier in a woman's life.

AB - Natural killer (NK) cells hold potential as a source of allogeneic cytotoxic effector cells for chimeric antigen receptor (CAR)-mediated therapies. Here, we explored the feasibility of transfecting CAR-encoding mRNA into primary NK cells and investigated how the intrinsic potential of discrete NK-cell subsets affects retargeting efficiency. After screening five second- and third-generation anti CD19 CAR constructs with different signaling domains and spacer regions, a third generation CAR with the CH2-domain removed was selected based on its expression and functional profiles. Kinetics experiments revealed that CAR expression was optimal after 3 days of IL15 stimulation prior to transfection, consistently achieving over 80% expression. CAR-engineered NK cells acquired increased degranulation toward CD19+ targets, and maintained their intrinsic degranulation response toward CD19- K562 cells. The response of redirected NK-cell subsets against CD19+ targets was dependent on their intrinsic thresholds for activation determined through both differentiation and education by killer cell immunoglobulin-like receptors (KIR) and/or CD94/NKG2A binding to self HLA class I and HLA-E, respectively. Redirected primary NK cells were insensitive to inhibition through NKG2A/HLA-E interactions but remained sensitive to inhibition through KIR depending on the amount of HLA class I expressed on target cells. Adaptive NK cells, expressing NKG2C, CD57, and self-HLA-specific KIR(s), displayed superior ability to kill CD19+, HLA low, or mismatched tumor cells. These findings support the feasibility of primary allogeneic NK cells for CAR engineering and highlight a need to consider NK-cell diversity when optimizing efficacy of cancer immunotherapies based on CAR-expressing NK cells.

AB - Cytokine-based therapies for cancer have not achieved widespread clinical success because of inherent toxicities. Treatment for pancreatic cancer is limited by the dense stroma that surrounds tumors and by an immunosuppressive tumor microenvironment. To overcome these barriers, we developed constructs of single domain antibodies (VHHs) against PD-L1 fused with IL-2 and IFNgamma. Targeting cytokine delivery in this manner reduced pancreatic tumor burden by 50%, whereas cytokines fused to an irrelevant VHH, or blockade of PD-L1 alone, showed little effect. Targeted delivery of IL-2 increased the number of intratumoral CD8+ T cells, whereas IFNgamma reduced the number of CD11b+ cells and skewed intratumoral macrophages toward the display of M1-like characteristics. Imaging of fluorescent VHH-IFNgamma constructs, as well as transcriptional profiling, demonstrated targeting of IFNgamma to the tumor microenvironment. Many tumors and tumor-infiltrating myeloid cells express PD-L1, rendering them potentially susceptible to this form of targeted immunotherapy. Cancer Immunol Res; 6(4); 389 401. (c)2018 AACR. PMID- 29459480 TI - Occupational exposure to pesticides is associated with differential DNA methylation. AB - OBJECTIVES: Occupational pesticide exposure is associated with a wide range of diseases, including lung diseases, but it is largely unknown how pesticides influence airway disease pathogenesis. A potential mechanism might be through epigenetic mechanisms, like DNA methylation. Therefore, we assessed associations between occupational exposure to pesticides and genome-wide DNA methylation sites. METHODS: 1561 subjects of LifeLines were included with either no (n=1392), low (n=108) or high (n=61) exposure to any type of pesticides (estimated based on current or last held job). Blood DNA methylation levels were measured using Illumina 450K arrays. Associations between pesticide exposure and 420 938 methylation sites (CpGs) were assessed using robust linear regression adjusted for appropriate confounders. In addition, we performed genome-wide stratified and interaction analyses by gender, smoking and airway obstruction status, and assessed associations between gene expression and methylation for genome-wide significant CpGs (n=2802). RESULTS: In total for all analyses, high pesticide exposure was genome-wide significantly (false discovery rate P<0.05) associated with differential DNA methylation of 31 CpGs annotated to 29 genes. Twenty of these CpGs were found in subjects with airway obstruction. Several of the identified genes, for example, RYR1, ALLC, PTPRN2, LRRC3B, PAX2 and VTRNA2-1, are genes previously linked to either pesticide exposure or lung-related diseases. Seven out of 31 CpGs were associated with gene expression levels. CONCLUSIONS: We show for the first time that occupational exposure to pesticides is genome-wide associated with differential DNA methylation. Further research should reveal whether this differential methylation plays a role in the airway disease pathogenesis induced by pesticides.

PMID- 29459481 TI - Catalytic activities of mammalian epoxide hydrolases with cis and trans fatty acid epoxides relevant to skin barrier function. AB - Lipoxygenase (LOX)-catalyzed oxidation of the essential fatty acid, linoleate, represents a vital step in construction of the mammalian epidermal permeability barrier. Analysis of epidermal lipids indicates that linoleate is converted to a trihydroxy derivative by hydrolysis of an epoxy-hydroxy precursor. We evaluated different epoxide hydrolase (EH) enzymes in the hydrolysis of skin-relevant fatty acid epoxides and compared the products to those of acid-catalyzed hydrolysis. In the absence of enzyme, exposure to pH 5 or pH 6 at 37 degrees C for 30 min hydrolyzed fatty acid allylic epoxyalcohols to four trihydroxy products. By contrast, human soluble EH [sEH (EPHX2)] and human or murine epoxide hydrolase-3 [EH3 (EPHX3)] hydrolyzed cis or trans allylic epoxides to single diastereomers, identical to the major isomers detected in epidermis. Microsomal EH [mEH (EPHX1)] was inactive with these substrates. At low substrate concentrations (<10 MUM), EPHX2 hydrolyzed 14,15-epoxyeicosatrienoic acid (EET) at twice the rate of the epidermal epoxyalcohol, 9R,10R-trans-epoxy-11E-13R-hydroxy-octadecenoic acid, whereas human or murine EPHX3 hydrolyzed the allylic epoxyalcohol at 31-fold and 39-fold higher rates, respectively. These data implicate the activities of EPHX2 and EPHX3 in production of the linoleate triols detected as end products of the 12R-LOX pathway in the epidermis and implicate their functioning in formation of the mammalian water permeability barrier.

AB - Omphalitis contributes significantly to morbidity and mortality in neonatal calves. Diagnosis of omphalitis is based on the local signs of inflammation-pain, swelling, local heat and purulent discharge. An abattoir trial identified an optimal, sign-based, scoring system for diagnosis of omphalitis. A sample of 187 calves aged between 7 and 15 days old were clinically examined for signs of umbilical inflammation and compared with postmortem examination of navels. On postmortem findings, 64 calves (34.2 per cent) had omphalitis. In the examined omphalitis cases, the most commonly affected umbilical structure was the urachus (78.1 per cent). Multivariable logistic regression revealed that thickening of the umbilical stump over 1.3 cm (P<0.001), discharge (P<0.001), raised local temperature (P=0.003) and the presence of umbilical hernia (P=0.024) were correlated and positive predictors of omphalitis. Discharge from the umbilical stump was associated with intra-abdominal inflammation (P=0.004). Assigning weights based on the multivariable logistic regression coefficients, a clinical scoring algorithm was developed. The cumulative score ranged from 0 to 9. Using this scoring system, calves were categorised as positive if their total score was >=2. This scoring method had a sensitivity of 85.9 per cent, specificity of 74.8 per cent and correctly classified 78.6 per cent of all calves. PMID- 29459489 TI - Fifteen-month duration of immunity for the serovar Grippotyphosa fraction of a tetravalent canine leptospirosis vaccine. AB - Forty-four specific pathogen-free beagles, median age 65 days, received two subcutaneous doses of either a commercially available, five-way combination vaccine or the same vaccine in combination with a tetravalent Leptospira bacterin (Canicola, Grippotyphosa, Icterohaemorrhagiae, Pomona). They were subsequently challenged with a pathogenic strain L kirschneri serovar Grippotyphosa 470 days following completion of the vaccination protocol. Titres of agglutinating serum antibodies were determined at various time points before and after both vaccination and challenge, along with postchallenge reisolation of the challenge organisms from blood and urine, and evaluation of renal histopathology. Clinical signs of generalised leptospirosis were not observed in any of the dogs after challenge. In order to demonstrate efficacy, leptospirosis was defined as having at least one positive urine sample and a positive renal histopathology score; or, in the absence of renal pathology, multiple positive urine samples. Leptospiremia was not demonstrated in any of the vaccinated dogs versus 27 per cent of the controls; leptospiruria was noted in 5 per cent of the vaccinates compared with 76 per cent of controls; and renal lesions were observed in 15 per cent of the vaccinates and 65 per cent controls. Using these criteria, the vaccine was able to significantly prevent leptospirosis (P=0.0001) in the vaccinated animals. This study establishes duration of immunity of at least 15 months for the prevention of disease and renal excretion of leptospires for the Leptospira serovar Grippotyphosa fraction of a quadrivalent Leptospira vaccine. PMID- 29459486 TI - Perturbing mitosis for anti-cancer therapy: is cell death the only answer? AB - Interfering with mitosis for cancer treatment is an old concept that has proven highly successful in the clinics. Microtubule poisons are used to treat patients with different types of blood or solid cancer since more than 20 years, but how these drugs achieve clinical response is still unclear. Arresting cells in mitosis can promote their demise, at least in a petri dish. Yet, at the molecular level, this type of cell death is poorly defined and cancer cells often find ways to escape. The signaling pathways activated can lead to mitotic slippage, cell death, or senescence. Therefore, any attempt to unravel the mechanistic action of microtubule poisons will have to investigate aspects of cell cycle control, cell death initiation in mitosis and after slippage, at single-cell resolution. Here, we discuss possible mechanisms and signaling pathways controlling cell death in mitosis or after escape from mitotic arrest, as well as secondary consequences of mitotic errors, particularly sterile inflammation, and finally address the question how clinical efficacy of anti-mitotic drugs may come about and could be improved.

PMID- 29459491 TI - SULFATION PATHWAYS: Alternate steroid sulfation pathways targeted by LC-MS/MS analysis of disulfates: application to prenatal diagnosis of steroid synthesis disorders. AB - The steroid disulfates (aka bis-sulfates) are a significant but minor fraction of the urinary steroid metabolome that have not been widely studied because major components are not hydrolyzed by the commercial sulfatases commonly used in steroid metabolomics. In early studies, conjugate fractionation followed by hydrolysis using acidified solvent (solvolysis) was used for the indirect detection of this fraction by GC-MS. This paper describes the application of a specific LC-MS/MS method for the direct identification of disulfates in urine, and their use as markers for the prenatal diagnosis of disorders causing reduced estriol production: STSD (steroid sulfatase deficiency), SLOS (Smith-Lemli-Opitz syndrome) and PORD (P450 oxidoreductase deficiency). Disulfates were detected by monitoring a constant ion loss (CIL) from the molecular di-anion. While focused on disulfates, our methodology included an analysis of intact steroid glucuronides and monosulfates because steroidogenic disorder diagnosis usually requires an examination of the complete steroid profile. In the disorders studied, a few individual steroids (as disulfates) were found particularly informative: pregn-5-ene-3beta,20S-diol, pregn-5-ene-3beta,21-diol (STSD, neonatal PORD) and 5alpha-pregnane-3beta,20S-diol (pregnancy PORD). Authentic steroid disulfates were synthesized for use in this study as aid to characterization. Tentative identification of 5xi-pregn-7-ene-3xi,20S-diol and 5xi-pregn-7-ene-3xi,17,20S-triol disulfates was also obtained in samples from SLOS affected pregnancies. Seven ratios between the detected metabolites were applied to distinguish the three selected disorders from control samples. Our results show the potential of the direct detection of steroid conjugates in the diagnosis of pathologies related with steroid biosynthesis.

PMID- 29459493 TI - Diagnostic strategy in segmentation defect of the vertebrae: a retrospective study of 73 patients. AB - BACKGROUND: Segmentation defects of the vertebrae (SDV) are non-specific features found in various syndromes. The molecular bases of SDV are not fully elucidated due to the wide range of phenotypes and classification issues. The genes involved are in the Notch signalling pathway, which is a key system in somitogenesis. Here we report on mutations identified in a diagnosis cohort of SDV. We focused on spondylocostal dysostosis (SCD) and the phenotype of these patients in order to establish a diagnostic strategy when confronted with SDV. PATIENTS AND METHODS: We used DNA samples from a cohort of 73 patients and performed targeted sequencing of the five known SCD-causing genes (DLL3, MESP2, LFNG, HES7 and TBX6) in the first 48 patients and whole-exome sequencing (WES) in 28 relevant patients. RESULTS: Ten diagnoses, including four biallelic variants in TBX6, two biallelic variants in LFNG and DLL3, and one in MESP2 and HES7, were made with the gene panel, and two diagnoses, including biallelic variants in FLNB and one variant in MEOX1, were made by WES. The diagnostic yield of the gene panel was 10/73 (13.7%) in the global cohort but 8/10 (80%) in the subgroup meeting the SCD criteria; the diagnostic yield of WES was 2/28 (8%). CONCLUSION: After negative array CGH, targeted sequencing of the five known SCD genes should only be performed in patients who meet the diagnostic criteria of SCD. The low proportion of candidate genes identified by WES in our cohort suggests the need to consider more complex genetic architectures in cases of SDV. PMID- 29459495 TI - Aplastic Anemia and Risk of Incident Atrial Fibrillation - A Nationwide Cohort Study. AB - BACKGROUND: This retrospective cohort study sought to follow up patients with aplastic anemia (AA) to evaluate their risk of developing atrial fibrillation (AF).Methods and Results:From the National Health Insurance Research Database of Taiwan, this study identified an AA cohort (n=3,921), a general population cohort (n=17,617,843) and a propensity score-matched none AA cohort (PSM non-AA cohort in brief, n=15,684) in 2000-2010. By the end of 2011, the incident AF was higher in the AA cohort than in the general population and PSM non-AA cohorts (8.94 vs. 1.14 and 6.47 per 1,000 person-years, respectively). The adjusted hazards ratio of AF for the AA cohort was 2.12 (95% confidence interval 1.46-3.08) compared with the PSM non-AA cohort, after controlling for covariates. However, after further controlling for the competing risk of death, adjusted subhazard ratio was 1.21 (95% CI 0.97-1.50). Among those who developed AF, the AA cohort had a higher mortality rate (83.7 vs. 51.1 per 100), but a lower rate of incident stroke (26.0 vs. 41.5 per 100), compared with the PSM non-AA cohort. CONCLUSIONS: Patients with AA could have an elevated risk for AF. The mortality risk increased further for those who develop AF. PMID- 29459494 TI - A dual-mode hemispherical sparse array for 3D passive acoustic mapping and skull localization within a clinical MRI guided focused ultrasound device. AB - Previous work has demonstrated that passive acoustic imaging may be used alongside MRI for monitoring of focused ultrasound therapy. However, past implementations have generally made use of either linear arrays originally designed for diagnostic imaging or custom narrowband arrays specific to in-house therapeutic transducer designs, neither of which is fully compatible with clinical MR-guided focused ultrasound (MRgFUS) devices. Here we have designed an array which is suitable for use within an FDA-approved MR-guided transcranial focused ultrasound device, within the bore of a 3 Tesla clinical MRI scanner. The array is constructed from 5 * 0.4 mm piezoceramic disc elements arranged in pseudorandom fashion on a low-profile laser-cut acrylic frame designed to fit between the therapeutic elements of a 230 kHz InSightec ExAblate 4000 transducer. By exploiting thickness and radial resonance modes of the piezo discs the array is capable of both B-mode imaging at 5 MHz for skull localization, as well as passive reception at the second harmonic of the therapy array for detection of cavitation and 3D passive acoustic imaging. In active mode, the array was able to perform B-mode imaging of a human skull, showing the outer skull surface with good qualitative agreement with MR imaging. Extension to 3D showed the array was able to locate the skull within +/-2 mm/2 degrees of reference points derived from MRI, which could potentially allow registration of a patient to the therapy system without the expense of real-time MRI. In passive mode, the array was able to resolve a point source in 3D within a +/-10 mm region about each axis from the focus, detect cavitation (SNR ~ 12 dB) at burst lengths from 10 cycles to continuous wave, and produce 3D acoustic maps in a flow phantom. Finally, the array was used to detect and map cavitation associated with microbubble activity in the brain in nonhuman primates.

AB - Preventive measures against soil-borne diseases need to be implemented before cultivation because very few countermeasures are available after the development of diseases. Some soils suppress soil-borne diseases despite the presence of a high population density of pathogens. If the suppressiveness of soil against soil borne diseases may be predicted and diagnosed for crop fields, it may be possible to reduce the labor and cost associated with excessive disinfection practices. We herein evaluated the suppressiveness of soils in fields with the long-term application of organic amendments by examining the growth of pathogenic Fusarium oxysporum co-cultivated with indigenous soil microorganisms on agar plates. Soils treated with coffee residue compost or rapeseed meal showed suppressiveness against spinach wilt disease by F. oxysporum f. sp. spinaciae or spinach wilt and lettuce root rot diseases by F. oxysporum f. sp. spinaciae and F. oxysporum f. sp. lactucae, respectively, and the growth of pathogenic Fusarium spp. on agar plates was suppressed when co-cultured with microorganisms in a suspension from these soils before crop cultivation. These results indicate the potential of the growth degree of pathogenic F. oxysporum estimated by this method as a diagnostic indicator of the suppressiveness of soil associated with the inhabiting microorganisms. A correlation was found between the incidence of spinach wilt disease in spinach and the growth degree of F. oxysporum f. sp. spinaciae by this co-cultivation method, indicating that suppressiveness induced by organic amendment applications against F. oxysporum f. sp. spinaciae is evaluable by this method. The co-cultivation method may be useful for predicting and diagnosing suppressiveness against soil-borne diseases.

AB - Many thermophiles thriving in a natural high-temperature environment remain uncultivated, and their ecophysiological functions in the biogeochemical cycle remain unclear. In the present study, we performed long-term continuous cultivation at 65 degrees C and 70 degrees C using a microbial mat sample, collected from a subsurface geothermal stream, as the inoculum, and reconstructed the whole genome of the maintained populations using metagenomics. Some metagenome-assembled genomes (MAGs), affiliated into phylum-level bacterial and archaeal clades without cultivated representatives, contained genes involved in nitrogen metabolism including nitrification and denitrification. Our results show genetic components and their potential interactions for the biogeochemical nitrogen cycle in a subsurface geothermal environment.

AB - We describe a case of choroid plexus carcinoma arising in the cerebrum of a 7 week-old male Sprague-Dawley rat. The tumor mass occupied the right lateral ventricle of the cerebrum. Histological analyses revealed that the epithelial tumor cells had proliferated in tubular, cribriform, papillary and solid growth patterns in the vicinity of the choroid plexus, with slight invasion into the cerebrum parenchyma. We divided the tumor cells into cuboidal, elongated and intermediate cells. Immunohistochemical studies showed that these tumor cells expressed relatively high levels of cytokeratin AE1/AE3, vimentin and glial fibrillary acidic proteins, and low levels of nestin, oligodendrocyte transcription factor and doublecortin proteins. The present case was diagnosed as a choroid plexus carcinoma with neuronal and glial differentiation.

The Rhizobium-cured fungus was prepared thoroughly by an antibiotic treatment, thereby allowing an examination of their effects on organic substrate utilization. Assays with Biolog(r) FF microplates revealed that the respiration potential for 52.6% of the tested compounds were significantly different between Rhizobium-harboring and -cured fungal hosts, indicating that organic substrate utilization by V. simplex Y34 was significantly influenced by the presence of the associated Rhizobium sp.

AB - The purpose of this study was to describe and assess the feasibility of a new intra-articular approach in the treatment of cranial cruciate ligament deficiency in dogs using an artificial ligament and a new bone-anchor system. Twelve canine cadavers weighting 26 to 45 kg were used in this ex-vivo study. Special tibial and femoral screws, two helicoils, and a high resistance artificial fiber compose the implant. Surgery was performed using the cranio-lateral approach to the stifle joint. Helicoil and tibial screw, connected to the fiber, were inserted in the center of the tibial insertion area of the cranial cruciate ligament. The fiber was passed over-the-top, tensioned, and fixed to the femoral screw, previously inserted with the helicoil in the distal part of the femur. Surgery was completed in all the cases. Occasional problems found during the insertion of the helicoils and screws were resolved with simple procedures. Post-operative clinical assessment showed negative cranial drawer test, negative cranial tibial thrust, and normal range of motion. Radiographic evaluation showed an appropriate positioning of both tibial and femoral implants in all the cases. The results of the first surgical appraisal of this new technique are encouraging, although further studies are necessary to demonstrate the in vivo efficacy of this procedure. PMID- 29459503 TI - First report of feline bocavirus associated with severe enteritis of cat in Northeast China, 2015. AB - Feline bocavirus (FBoV) is a newly identified bocavirus of cats in the family Parvoviridae. A novel FBoV HRB2015-LDF was first identified from the cat with severe enteritis in Northeast China, with an overall positive rate of 2.78% (1/36). Phylogenetic and homologous analysis of the complete genome showed that FBoV HRB2015-LDF was clustered into the FBoV branch and closely related to other FBoVs, with 68.7-97.5% identities. And the genes of VP1, NPA and NS1 shared 70.7 97.6, 72.4-98.6 and 67.2-98.0% nucleotide identities with other FBoVs, respectively. The results suggested that the FBoVs could be divided into two distinct lineages, and the difference of nucleotide identities was >20-30% between the lineages. PMID- 29459504 TI - Isolation and molecular characterization of parainfluenza virus 5 in diarrhea affected piglets in China. AB - Recently, parainfluenza virus 5 (PIV5) infection has been increasingly reported in mammals. In this study, five PIV5 strains were isolated from diarrhea-affected piglets from four provinces or municipalities in China. An F-gene-based phylogenetic tree indicated that the five isolated strains were closely related to the PIV5 strain ZJQ-221 from a lesser panda in China, and the PIV5 strain 1168 1 from a dog in South Korea. The new isolates differed genetically from other pig, calf, rhesus macaque kidney cells, human, and dog PIV5 reference strains. Our study reveals the presence of PIV5 in intestinal tissue samples collected from diarrhea-affected piglets, and provides novel information regarding the epidemiology and tissue tropism of PIV5. PMID- 29459505 TI - Acute hemorrhagic diarrhea syndrome associated with contaminated foreign bodies (used feminine hygiene products) in a Golden Retriever dog. AB - A one-year-old male Golden Retriever presented with acute onset of vomiting and hemorrhagic diarrhea since 2 days. The dog was depressed, showing abdominal pain, 12% dehydration, tachycardia, and a bounding pulse. Diagnostic imaging showed severe dilatation and fluid retention of the entire gastrointestinal tract with decreased motility. A foreign body was found in the gastroduodenal region, but there was no obstruction or plication. The dog was tentatively diagnosed with acute hemorrhagic diarrhea syndrome and rapidly recovered after supportive treatment. However, on the morning of day 4, anorexia and vomiting recurred, and diagnostic imaging revealed intestinal plication with free peritoneal fluid, not found on the previous image. An emergency laparotomy revealed the foreign body to be two used feminine hygiene products. These contaminated products were suspected to induce acute hemorrhagic diarrhea syndrome, and led to subsequent complication in this large dog.

AB - In this study, we measured the quantity of marine-derived tocopherol (MDT), a monounsaturated vitamin E (VE), stored in the body tissue of mice fed with a diet containing a VE-rich fraction extracted from salmon roe. We first prepared the calibration curves for the MDT concentration using an HPLC-fluorescence system. Ranging from 0.016 to 50 MUg/mL, the slope was expressed as first-order equations, with R2 values = 0.99. The mice were fed with an AIN-93 based diet containing MDT in doses of 21.4 mg/kg for 4 weeks, and the storage in the heart, lung, liver, stomach, small intestine, large intestine, kidney, pancreas, spleen, testis, skeletal muscle, visceral white adipose tissue (WAT), subcutaneous WAT and brain was quantified. MDT was widely distributed in tissues throughout the whole body, with higher accumulations observed in the adipose tissue, liver and kidney. These results demonstrate means to estimating the MDT concentration in natural products and in the bodies of animals and contribute to the understanding of the physiological functions of MDT in relation to human health.

AB - Fatty acid methyl esters were synthesized from palm fatty acid distillate (PFAD) and methanol in a packed bed reactor via lipase-catalyzed esterification. The PFAD consisted of 91 wt% of free fatty acids, 2 wt% monoacylglycerides, 3 wt% diacylglycerides, and 4 wt% triacylglycerides. t-Butanol was employed as a reaction medium and a mixed enzyme consisting of Lipozyme TL IM from Thermomyces lanuginosus and Novozym 435 from Candida antarctica was employed as the biocatalyst. The effect of mixed enzyme was investigated and the optimum blending ratio (w/w) of Novozym 435 to Lipozyme TL IM was 5:95. Using the mixed enzyme, the optimum molar ratio (PFAD to methanol) and temperature were determined to be 1:6 and 30 degrees C, respectively. Under the optimized conditions, the maximum yield of ca. 96% was achieved. PMID- 29459508 TI - Hepatic Regeneration and Reno-Protection by Fish oil, Nigella sativa Oil and Combined Fish Oil/Nigella sativa Volatiles in CCl4 Treated Rats. AB - The aim of the present research was to investigate the effect of fish oil, crude Nigella sative oil and combined fish oil/Nigella sative volatile oil as hepato regenerative and renal protective supplements. The oils were administered as emulsions to rat model with liver injury induced by CCl4. Plasma activities of transaminases (AST and ALT) were evaluated as liver function indicators, while plasma creatinine and urea and creatinine clearance were determined as markers of kidney function. Plasma malondialdehyde (MDA), nitrite (NO) and tumor necrosis factor-alpha (TNF-alpha) were estimated to assess the exposure to oxidative stress and subsequent inflammation. Liver fat was extracted and their fatty acids' methyl esters were determined using gas chromatography. Results showed that plasma activities of AST and ALT were significantly higher in CCl4 control group compared to control healthy group. Plasma levels of creatinine and urea increased significantly in CCl4 control, while creatinine clearance was reduced significantly in the same group. All rat treated groups given the three oil emulsions showed improvement in liver function pointing to the initiation of liver regeneration. The combination of fish oil/Nigella sative volatiles showed the most promising regenerative activity. Oxidative stress and inflammation which were increased significantly in CCl4 control group showed improvement on administration of the three different oil emulsions. Fatty acids methyl ester of liver fat revealed that rats treated with fish oil/Nigella sative volatile oil presented the highest content of unsaturated fatty acids (45.52% +/- 0.81) while fish oil showed the highest saturated fatty acids (53.28% +/- 1.68). Conclusion; Oral administration of oil emulsions of native fish oil, Nigella sative crude oil and combined fish oil/Nigella sative volatile oil reduced liver and kidney injury in rat model of CCl4 through exerting anti-inflammatory and antioxidant activity. Fish oil/Nigella sative volatile oil emulsion was the most promising hepato regenerative and reno-protective formula among the different groups. PMID- 29459509 TI - Study of Trans Fatty Acid Formation in Oil by Heating Using Model Compounds. AB - The intake of trans fatty acids (TFAs) in foods changes the ratio of low density lipoprotein (LDL) to high density lipoprotein (HDL) cholesterol in blood, which causes cardiovascular disease. TFAs are formed by trans isomerization of unsaturated fatty acids (UFAs). The most recognized formation mechanisms of TFAs are hydrogenation of liquid oil to form partially hydrogenated oil (PHO,) and biohydrogenation of UFAs to form TFA in ruminants. Heating oil also forms TFAs; however, the mechanism of formation, and the TFA isomers formed have not been well investigated. In this study, the trans isomerization mechanism of unsaturated fatty acid formation by heating was examined using the model compounds oleic acid, trioleate, linoleic acid, and trilinoleate for liquid plant oil. The formation of TFAs was found to be suppressed by the addition of an antioxidant and argon gas. Furthermore, the quantity of formed TFAs correlated with the quantity of formed polymer in trioleate heated with air and oxygen. These results suggest that radical reactions form TFAs from UFAs by heating. Furthermore, trans isomerization by heating oleic acid and linoleic acid did not change the original double bond positions. Therefore, the distribution of TFA isomers formed was very simple. In contrast, the mixtures of TFA isomers formed from PHO and ruminant UFAs are complicated because migration of double bonds occurs during hydrogenation and biohydrogenation. These findings suggest that trans isomerization by heating is executed by a completely different mechanism than in hydrogenation and biohydrogenation. PMID- 29459510 TI - Effects of Fatty Acid Addition to Oil-in-water Emulsions Stabilized with Sucrose Fatty Acid Ester. AB - Adding fatty acids to an oil-in-water (O/W) emulsion changes the stability of the emulsion. In this study, we prepared a series of O/W emulsions consisting of oil (triolein/fatty acid mixture), water and a range of surfactants (sucrose fatty acid esters) with varying hydrophilic-lipophilic balance (HLB) in order to determine the effects of alkyl chain length and the degree of unsaturation of the fatty acid molecules on the stability of the emulsions. As a result, sucrose fatty acid esters with HLB = 5-7 were suitable for obtaining O/W emulsions. In addition, the creaming phenomenon was inhibited for 30 days or more when fatty acids having a linear saturated alkyl chain with 14 or more carbon atoms were added. These findings are useful for designing stable O/W emulsions for food and cosmetic products. PMID- 29459511 TI - Optimization of Supercritical Carbon Dioxide Extraction of Eucommia ulmoides Seed Oil and Quality Evaluation of the Oil. AB - Supercritical carbon dioxide extraction (SC-CO2) technology was used to extract oil from Eucommia ulmoides seed. The optimum conditions and significant parameters in SC-CO2 were obtained using response surface methodology (RSM). The qualities of the extracted oil were evaluated by physicochemical properties, fatty acid composition, vitamin E composition. It was found that the optimum extraction parameters were at pressure of 37 MPa, temperature of 40 degrees C, extraction time of 125 min and CO2 flow rate of 2.6 SL/min. Pressure, temperature and time were identified as significant parameter effecting on extraction yield. The importance of evaluated parameters decreased in the order of pressure > extraction time > temperature > CO2 flow rate. GC analysis indicated that E. ulmoides seed oil contained about 61% of linolenic acid and its fatty acid composition was similar with that of flaxseed oil and perilla oil. The content and composition of vitamin E was determined using HPLC. The E. ulmoides seed oil was rich in vitamin E (190.72 mg/100 g), the predominant vitamin E isomers were gamma- tocopherol and delta- tocopherol, which accounted for 70.87% and 24.81% of the total vitamin E, respectively. The high yield and good physicochemical properties of extracted oil support the notion that SC-CO2 technology is an effective technique for extracting oil from E. ulmoides seed.

AB - Ion-pair amphiphiles (IPAs, also known as catanionic surfactants) are lipid-like double-chained molecules potentially used for fabricating liposome-like vesicular drug and gene carriers. Frequently ethanol and cholesterol are added to modulate the properties of their bilayer membranes. Effects of ethanol and cholesterol on the fundamental properties of IPA bilayers such as thermotropic phase behavior, however, is not known. In this work, the bilayer phase transition behavior of two IPAs (decyltrimethylammonium-tetradecyl sulfate, DeTMA-TS, and dodecyltrimethylammonium-dodecyl sulfate, DTMA-DS) in tris buffer with various amounts of ethanol was studied by using differential scanning calorimetry (DSC). Effect of cholesterol (CHOL) addition on bilayer phase transition of IPAs with 20 vol% ethanol was thereafter systematically investigated. The experimental results showed that the main phase transition temperature (Tm) was monotonously decreased with the increase of ethanol concentration up to 30 vol%. The degree of Tm depression by ethanol is essentially the same for the two IPAs regardless of different symmetry in the hydrocarbon chains. Further addition of CHOL, however, caused a slight decrease in Tm on the one hand and a significant decrease in the enthalpy of phase transition on the other hand. When the added CHOL exceeded a specific amount, the phase transition disappeared. More hasty disappearance of phase transition was found for IPA with asymmetric structure than the symmetric one. Possible mechanisms of ethanol effect based on binding in the headgroup region of the bilayers and CHOL effect based on opposite (condensing and disordering) interactions with IPA molecules in bilayers, respectively, were proposed.

AB - A new method for utilization of hydrogel is proposed here for the preparation of solid base catalysts for the transesterification of vegetable oil. When a solution of KF is mixed with a solution of Ca(NO3)2, CaF2 is obtained and inactive as a catalyst in the transesterification of vegetable oils. The catalysts were synthesized by the sequential incorporation of KF and/or Ca(NO3)2 solutions into the hydrogel upon microwave irradiation and then the as-obtained hydrogel was calcined at 800 degrees C for 5 hours to eliminate the template and yield catalysts for the biodiesel productions. The prepared catalysts obtained by the different ways in the incorporation of ions into the hydrogel showed different physical properties and catalytic activities in the transesterification of soybean oil. All catalysts, except the low concentration of Ca(NO3)2, exhibiting the high activity yielding more than 90% FAME after 1 hour at 65 degrees C, using oil to methanol molar ratio of 1:15 and 10 wt% of catalyst amounts. PMID- 29459514 TI - Activation of Macrophages in vitro by Phospholipids from Brain of Katsuwonus pelamis (Skipjack Tuna). AB - The biological activities of phospholipids (PLs) have attracted people's attention, especially marine phospholipids with omega-3 polyunsaturated fatty acids DHA and EPA. In this study, we investigated the immunity activation of macrophages in vitro by phospholipids from skipjack brain. The phospholipids were extracted with hexane and ethanol ultrasonication instead of the traditional method of methanol and chloroform. The content of phospholipids from Skipjack brain was 19.59 g/kg by the method (the ratio of hexane and ethanol 2:1, 40 min, 35 degrees C, 1:9 of the ratio of material to solvent, ultrasonic power 300W, ultrasonic extraction 2 times). The RAW264.7 macrophages were stimulated by the phospholipids from the Skipjack, by which the volume, viability and phagocytosis of macrophages were increased. The concentration of NO and the activity of SOD of the cells were also enhanced. The gene expressions of IL-1beta, IL-6, iNOS and TNF-alpha mRNA assayed by RT-PCR were up-regulated. Phospholipids from brain of Skipjack Tuna could activate macrophages immunity which displayed to induce pro inflammatroy cytokines mRNA expression. PMID- 29459516 TI - Development of a Novel Spontaneous Emulsification Method for Peptide Delivery Using Porous Silica Particles. AB - A new emulsification technique using porous silica particles was studied as a facile and instantaneous formation method for thermodynamically unstable emulsions. In this study, oil encapsulated in silica particles was released instantly upon the addition of a phosphate buffer, forming an oil-in-water (O/W) emulsion. Emulsion formation was inhibited or promoted using lipophilic or hydrophilic surfactant additives, respectively. We concluded that this phenomenon is affected by the wettability of the soybean oil on the silica surface, which is controlled by the surfactant. We prepared submicron size emulsions in a simple method involving the addition of the silica particles to an aqueous solution. This spontaneous emulsification technique could be applied to the formation of solid-in-oil-in-water (S/O/W) emulsions for oral delivery of hydrophilic peptide medicine. PMID- 29459515 TI - Yuzu (Citrus junos Tanaka) Peel Attenuates Dextran Sulfate Sodium-induced Murine Experimental Colitis. AB - Ulcerative colitis is a well-known inflammatory bowel disease. Although there are drugs that are effective against this disease, the prevention and attenuation of ulcerative colitis by food rich in functional ingredients without side effects is desired because some drugs have side effects. In this study, we investigated the effects of yuzu (Citrus junos Tanaka), a citrus fruit native to northeast Asia, on a mouse dextran sulfate sodium (DSS)-induced colitis model. Mice given drinking water containing DSS showed significant weight loss, colon shortening, diarrhea, and visible fecal blood. In contrast, mice fed a diet containing 5% yuzu peel for 14 d before receiving DSS showed significant attenuation of these phenotypes. To clarify the mechanism underlying the attenuation, we investigated the anti-inflammatory and antioxidant effects of yuzu peel. We found that yuzu peel extract suppressed tumor necrosis factor-alpha (TNF-alpha) production in lipopolysaccharide (LPS)-stimulated mice and murine macrophage cell line through suppression of nuclear factor-kappaB (NF-kappaB) activation. In addition, we confirmed that yuzu peel extract had a moderate antioxidant effect. These results suggest that yuzu peel attenuates the pathologies of DSS-induced colitis by coordinately suppressing inflammation and oxidative stress against lipids in vivo.

PMID- 29459517 TI - Reduced Lung Function and Cerebral Small Vessel Disease in Japanese Men: the Shiga Epidemiological Study of Subclinical Atherosclerosis (SESSA). AB - AIM: We aimed to investigate the association between reduced lung function and cerebral small vessel diseases via cranial magnetic resonance imaging (MRI) in the cross-sectional study of the general Japanese population. METHODS: We recruited participants aged >=40 years from the general population of a single city in Japan. We clarified the comorbidities and treatments, smoking habits, second-hand smoke exposure, current alcohol consumption, education level, exercise habits, and occupation. The pulmonary function test was performed to assess the forced expiratory volume in 1 second (FEV1) % predicted and forced vital capacity (FVC) % predicted values. Cranial MRI was performed to evaluate the white matter lesions (WMLs) and lacunar infarcts. We examined the association of the WMLs and lacunar infarcts with a 1-standard deviation (SD) lower in the FEV1 % predicted and FVC % predicted, on the basis of the smoking status. RESULTS: A total of 473 men were examined. The association of WMLs and lacunar infarcts with the spirometry-based indices were significant only in never smokers. The association between lung function impairment and cerebral small vessel disease did not change after further adjusting for second-hand smoke exposure. CONCLUSION: In a community-based sample of Japanese men, we found an association between reduced lung function and WMLs and lacunar infarcts in never smokers. PMID- 29459518 TI - Noninvasive Assessment of Stenotic Severity and Plaque Characteristics by Coronary CT Angiography in Patients Scheduled for Carotid Artery Revascularization. AB - AIMS: Coronary artery atherosclerosis in patients needing carotid revascularization has not been fully clarified. The aim of this study was to evaluate the stenotic severity and plaque characteristics of coronary arteries by coronary computed tomography angiography (CTA) in patients scheduled for carotid artery stenting (CAS) or carotid endarterectomy (CEA). METHODS: We performed coronary CTA after carotid ultrasound (US) in 164 patients (81.7% male, aged 68.1+/- 12.2 years) from 2014 to 2016. Of all, 70 were scheduled for CAS or CEA (CAS/CEA group) and 94 were not (non-CAS/CEA group). Carotid US and coronary CTA were compared for the evaluation of stenotic severity and plaque characteristics of each vessel between CAS/CEA and non-CAS/CEA groups. RESULTS: Between the two groups, there were significant differences in the presence of significant stenosis (SS: >=70% stenosis of coronary artery) (55.7% vs. 39.4%, P=0.038), triple-vessel disease (TVD)/left main trunk (LMT) (SS in each of three epicardial vessels and/or LMT) (24.3% vs. 7.5%, P= 0.0025), and high-risk plaque (HRP: positive remodeling and/or low attenuation) (55.7% vs. 24.5%, P<0.0001). CAS/CEA was independently associated with TVD/LMT (OR=2.30, 95%CI: 1.14-8.59, P=0.026) and HRP (OR=3.17, 95%CI: 1.57-6.54, P=0.0012) in multivariable logistic regression analysis. Similarly, vulnerable plaque (78.6% vs. 2.1%, P<0.0001) as well as severe stenosis of carotid artery (98.6% vs. 0%, P<0.0001) was seen more often in CAS/CEA than in non-CAS/CEA group. CONCLUSIONS: The prevalence of TVD/LMT and HRP determined by coronary CTA is higher in patients needing CAS/CEA than in those without. Management of systemic atherosclerosis is required in the perioperative period of CAS/CEA. PMID- 29459520 TI - [ANAPHYLAXIS GUIDELINE].

AB - BACKGROUND: This study aimed to evaluate the clinical accuracy of specific IgE (sIgE) to Ara h 2 in the diagnosis of peanut allergy (PA). We also investigated the prevalence of complications with other nut allergies in PA patients. METHODS: The Ara h 2-sIgE titer was examined in patients with positive results for sIgE to peanut from April 2014 to March 2015. The presence or absence of PA was diagnosed based on an oral food challenge or a convincing clinical history. The characteristics of 217 patients (including 90 PA patients) were retrospectively evaluated. RESULTS: At >=0.35UA/mL, Ara h 2 showed 85.6% sensitivity in the diagnosis of PA. At the clinically-designated positive cut-off value (>=4.0UA/mL), the positive predictive value was 93.1% and the specificity was 96.9%. However, the Ara h 2-sIgE levels were not correlated with the threshold dose or the severity of the symptoms that were provoked in the peanut challenge (n=42). Nine (10%) of the PA patients also had allergies to other tree nuts. CONCLUSION: The re-evaluation of the clinically-designated positive Ara h 2-sIgE cut-off value revealed that the cut-off value was appropriate. The differential diagnosis of tree nut allergies was suggested to be important in PA patients. PMID- 29459525 TI - [THE CAUSES OF ACUTE COUGH: A SINGLE-CENTER STUDY IN JAPAN]. AB - BACKGROUND: Cough is the most frequent presenting complaint in clinics, and is classified into the following three groups: acute, subacute and chronic. The major causes of acute cough are infectious diseases, however, few observations on acute cough have been reported. METHODS: We retrospectively assessed the causes of acute cough among patients who had visited the respiratory clinic of our hospital because of acute cough from September 2014 to August 2015. RESULTS: Of 374 patients (195 females, mean age 60.3 years) who visited the clinic complaining of cough, 129 patients (63 females, mean age 61.5 years) suffered from acute cough. All acute cases were stratified into two groups based on the presence (n=43) or absence (n=86) of abnormal findings on the chest X-ray. The main causes of acute cough with abnormal findings were pneumonia (46.5%), interstitial pneumonia (18.6%) and lung cancer (16.3%). The main causes of acute cough without abnormal findings were respiratory tract infection (39.5%), post infectious cough (18.6%) and bronchial asthma (17.4%). Acute cough was the primary complaint in 29.5% and 19.6% of all patients diagnosed with bronchial asthma and cough variant asthma, respectively. CONCLUSION: Non-infectious diseases including asthma as well as infectious diseases could be the causes in acute cough without abnormal findings on the chest X-ray. PMID- 29459526 TI - [THE COURSE OF ASTHMA SYMPTOMS IN JAPANESE CHILDREN; THE FIRST REPORT FROM A MULTICENTER PROSPECTIVE COHORT STUDY]. AB - BACKGROUND: The use of asthma control guidelines and anti-inflammatory drugs have significantly decreased the number of severe asthma cases including death from asthma. However, there are few prospective cohort studies among pediatric asthma patients in Japan describing the course of asthma symptoms with the treatment taken into consideration. METHOD: We recruited a total of 851 children diagnosed with asthma through 90 hospitals and clinics in 2004 to 2006. Questionnaires were posted annually to collect data on their asthma symptoms, treatment and environmental exposures. We analyzed the disease course in the first 5 years among the children who were registered at age 4 or younger. RESULTS: The disease course of a total of 641 children, aged 2.8+/-1.1 (mean+/-SD) at registration were analyzed. The proportion of children who had intermittent symptoms increased from 37.6% at registration to 86.5% at 5 years, and the proportion of children with intermittent severity increased from 7.0% to 38.9%, showing a significant decrease in the overall severity. The proportion of children using beta2 stimulants decreased from 87.8% at registration to 53.5% at 5 years, while the use of inhaled cortico-steroids were 41.6% at registration and 38.1% at 5 years. CONCLUSION: Most of the children with pre-school onset asthma had their symptoms controlled, and had decreased severity over 5 years.

AB - A 47-year old man presented to our hospital with a 6-month history of malaise, cough and dyspnea on exertion. Laboratory testing revealed the severe hyponatremia. A chest X-ray showed bilateral diffuse micronodules. Anti Trichosporon asahii antibody and environmental provocation test were positive. Bronchoalveolar lavage fluid showed lymphocytosis and low CD4/8 ratio. The specimens obtained by transbronchial lung biopsy revealed alveolitis. Based on these findings, the patient was diagnosed as having summer-type hypersensitivity pneumonitis (SHP). The patient was treated with antigen avoidance and oral corticosteroid. The hyponatremia caused by syndrome of inappropriate secretion of antidiuretic hormone (SIADH) was treated with normal saline and water restriction. Serum sodium level was improved with treatment of SHP, which suggested the relevance between SHP and SIADH.

AB - BACKGROUND: Japanese cypress pollen is a major causative allergen of seasonal allergic rhinitis in Japan. Although ImmunoCAP-specific immunoglobulin E (IgE) reagent Japanese cypress pollen has been widely used as a diagnostic aid, its sensitivity requires enhancement. This study evaluated an improved version of this reagent. METHODS: Serum samples from 61 subjects who underwent Japanese cypress pollen exposure testing in an environmental challenge chamber in Chiba University were assessed using the conventional ImmunoCAPspecific IgE Japanese cypress pollen product and the improved product. In addition, specific IgE for Cha o 1 and Cha o 2, the primary allergen components of Japanese cypress pollen, was evaluated and their reactivity to specific IgE was compared between the conventional and improved products. RESULTS: The antibody titer of the improved product was approximately 1.8-fold that of the conventional product. In addition, higher correlations with Cha o 1 and Cha o 2 were observed for the improved product than for the conventional product. The clinical sensitivity (>=class 2) in 56 exposure test-positive subjects was better for the improved product (80.4%) than for the conventional product (71.4%). CONCLUSIONS: An improvement of the ImmunoCAP-specific IgE reagent Japanese cypress pollen resulted in enhanced Japanese cypress pollen-specific IgE sensitivity. The primary reason for this appeared to be an improved Cha o 1- and Cha o 2-specific IgE detectability. PMID- 29459529 TI - [galactose-alpha-1,3-galactose (alpha-gal)]. PMID- 29459530 TI - ?

PMID- 29459533 TI - Macromolecular crowded conditions strengthen contacts between mouse oocytes and companion granulosa cells during in vitro growth. AB - Macromolecular crowded culture medium formed by addition of polyvinylpyrrolidone (PVP; molecular weight = 360 000), positively influences the viability, growth, and development of bovine oocytes. Owing to its apparently various effects, uncovering the specific mechanisms of crowding responsible for these outcomes is important. The present study was conducted to determine the effects of crowding on oocytes with a particular focus on the intimacy of contacts between oocyte and cumulus/granulosa cells. Growing mouse oocyte-granulosa cell complexes were cultured for 10 days in a modified alpha-minimum essential medium, supplemented with PVP at a concentration of 0%, 1%, 2%, or 3% (w/v). Although the complexes developed in all groups, 2% and 3% PVP medium induced a substantial morphological modification, and a larger proportion of oocytes associated with cumulus cells survived in 3% PVP medium than in the 0% or 1% PVP medium. No significant difference was found in the frequencies of polar body extrusion (78-88%) and blastocyst formation (approximately 40%) after in vitro fertilization among the experimental groups. Confocal laser scanning microscopy indicated a higher number of transzonal processes reaching the oocyte from cumulus cells in 2% PVP medium than in 0% PVP medium. Transmission electron microscopy depicted close adhesion of the oocyte with cumulus cells in 2% PVP medium -bearing a resemblance to their in vivo counterparts- and loose adhesion in 0% PVP medium. In conclusion, we found that a mechanism for the action of crowded conditions involves the strengthening of contacts and communication between oocytes and companion cumulus/granulosa cells.

AB - Synthetic MRI can provide proton density (PD), T1 value, T2 value for each pixel by only one data acquisition and can create various contrast-weighted images. The aim of this study is to evaluate the effect on the calculation of the T1.T2 value when changing the scan parameters for synthetic MRI. In the phantom study, when changing 1st TE/2nd TE/TR/TSE factor, the effect on the T1.T2 value calculated by synthetic MRI was examined. In the volunteer study, the brain was imaged and compared with known T1.T2 value. In phantom study, the effect on the T2 value by the 1st TE/2nd TE/TSE factor was shown. In volunteer study, there was no problem in the calculated value of brain parenchyma. However, the T2 value of cerebrospinal fluid had the error of known value. The results show that it is necessary to set appropriate scan parameters on synthetic MRI. PMID- 29459538 TI - [Development of a Striatal and Skull Phantom for Quantitative 123I-FP-CIT SPECT]. AB - BACKGROUND: 123Iodine-labelled N-(3-fluoropropyl) -2beta-carbomethoxy-3beta-(4 iodophenyl) nortropane (123I-FP-CIT) single photon emission computerized tomography (SPECT) images are used for differential diagnosis such as Parkinson's disease (PD). Specific binding ratio (SBR) is affected by scattering and attenuation in SPECT imaging, because gender and age lead to changes in skull density. It is necessary to clarify and correct the influence of the phantom simulating the the skull. PURPOSE: The purpose of this study was to develop phantoms that can evaluate scattering and attenuation correction. METHODS: Skull phantoms were prepared based on the measuring the results of the average computed tomography (CT) value, average skull thickness of 12 males and 16 females. 123I FP-CIT SPECT imaging of striatal phantom was performed with these skull phantoms, which reproduced normal and PD. SPECT images, were reconstructed with scattering and attenuation correction. SBR with partial volume effect corrected (SBRact) and conventional SBR (SBRBolt) were measured and compared. RESULTS: The striatum and the skull phantoms along with 123I-FP-CIT were able to reproduce the normal accumulation and disease state of PD and further those reproduced the influence of skull density on SPECT imaging. The error rate with the true SBR, SBRact was much smaller than SBRBolt. CONCLUSION: The effect on SBR could be corrected by scattering and attenuation correction even if the skull density changes with 123I FP-CIT on SPECT imaging. The combination of triple energy window method and CT attenuation correction method would be the best correction method for SBRact. PMID- 29459539 TI - [Optimization of Scan Parameters for Patient without Breath Hold in Chest by Computed Tomography]. AB - This study aims to establish optimal scan parameters by high temporal resolution computed tomography (CT) scan for emergency patients who cannot hold their breath. First, we investigated scan parameters that can reduce the effect of motion by evaluating motion artifacts from the moving phantom scan and the temporal sensitivity profile (TPS) measurement. Second, we confirmed the standard deviation (SD) of the CT values as well as the operating time and exposure dose. As the results, plan C [rotation time: 0.275 s, detector rows: 80, pitch factor (PF): 1.100] and plan E (rotation time: 0.275 s, detector rows: 100, PF: 0.880) demonstrated high temporal resolution. The difference between the two is PF. The noise of plan C increased because PF is higher than plan E. This is also evident from the results of SD measurement. Our study demonstrates that the optimal parameters for patients who cannot hold their breath in the emergency care are plan C and plan E. In conclusion, we clarified necessary optimal scan parameters to provide clinical image that has more diagnostic information by reducing the effect of breath motion for emergency patients. PMID- 29459540 TI - [Coronary Computed Tomography Angiography for Patients with Atrial Fibrillation: Feasibility of Prospective Electrocardiography-gated Diastolic Acquisition with a Manual Exposure-termination Technique]. AB - Coronary computed tomography angiography (CCTA) was performed in 283 patients with atrial fibrillation (Af) using a prospective electocardiogeaphic gated scanning with a manual exposure-termination technique. When preparatory 5-beat scanning contained at least one RR interval longer than 800 ms, 5-beat diastolic scanning (R+800 ms protocol) was selected. When no RR interval longer than 800 ms was observed, 2-beat scanning starting at end-systolic phase (R+210 ms to R protocol) was chosen. In R+800 ms protocol, we manually terminated scanning when motion free real-time reconstruction image was confirmed. R+800 ms protocol was applied in 95% of the cases and required an average of 2 cardiac cycles, providing motion-free images in 91% of the patients. The mean exposure dose was less than that with R+210 ms to R protocol. Using the protocols above, 90% of the all patients with Af provided motion free images and 99% of them were evaluable. PMID- 29459541 TI - [Measurement Accuracy of Fat and Iron Deposits in the Liver Using 1H-MRS (HISTO)]. AB - 1H-MRS, which is a method of measuring fat and iron deposits in the liver, has a single voxel spectroscopy imaging method called high-speed T2-corrected multiecho (HISTO) based on the STEAM method. If HISTO measurement accuracy is high, it will be one of the biomarkers, so the measurement accuracy was examined. We imaged a self-made phantom simulating a known amount of fat and iron deposition in the liver. A regression analysis of HISTO-measured values for hepatic fat phantom was performed. In addition, regression analysis was performed on the hepatic iron phantom for the R2 values obtained from the T2 values measurement and the actually measured value of the HISTO. From the regression analysis, the correlation coefficients were 0.999, 0.992 and 0.977, respectively. The measurement accuracy of HISTO is high, and the reliability of the obtained fat and iron deposit value is high.

AB - Portable radiography is available for the patient who is postoperative, severe condition and old. As they have weak immunity, it is important to prevent from hospital infection. Wrapping of 14*14 inch or 14*17 inch X-ray cassette by a plastic (polyethylene) bag a little bit bigger than the cassette was proposed for infection prevention in portable radiography. How to wrap the cassette easily was devised using the sheath of a polyester bag cutting at the bottom. In radiography with the grid, the plastic bag fastens the X-ray grid to the cassette substantially without any other means. In addition, the wrapped cassette, or the cassette with grid covered by the foamed plastic sheet alleviates patient's discomfort. PMID- 29459544 TI - [Comparison of Organ Dose Calculation Using Monte Carlo Simulation and In-phantom Dosimetry in CT Examination]. AB - Direct measurement of each patient organ dose from computed tomography (CT) is not possible. Most methods to estimate patient organ dose is using Monte Carlo simulation with dedicated software. However, the method and the relative differences between organ dose simulation and measurement is unclear. The purpose of this study was to compare organ doses evaluated by Monte Carlo simulation with doses evaluated by in-phantom dosimetry. The simulation software Radimetrics (Bayer) was used for the calculation of organ dose. Measurement was performed with radio-photoluminescence glass dosimeter (RPLD) set at various organ positions within RANDO phantom. To evaluate difference of CT scanner, two different CT scanners were used in this study. Angular dependence of RPLD and measurement of effective energy were performed for each scanner. The comparison of simulation and measurement was evaluated by relative differences. In the results, angular dependence of RPLD at two scanners was 31.6+/-0.45 mGy for SOMATOM Definition Flash and 29.2+/-0.18 mGy for LightSpeed VCT. The organ dose was 42.2 mGy (range, 29.9-52.7 mGy) by measurements and 37.7 mGy (range, 27.9 48.1 mGy) by simulations. The relative differences of organ dose between measurement and simulation were 13%, excluding of breast's 42%. We found that organ dose by simulation was lower than by measurement. In conclusion, the results of relative differences will be useful for evaluating organ doses for individual patients by simulation software Radimetrics.

AB - Children born small for gestational age (SGA) are at a higher risk for metabolic disorders later in life. In this study, we aimed to characterize young SGA children without catch-up growth and evaluate the effects of GH treatment on endocrinological, metabolic, and immunological parameters. Study design is a one year single hospital-based study included prospective observation of SGA patients during 12 months of GH treatment. Clinical and laboratory profiles of SGA children at baseline were compared with controls born appropriate size for age. Twenty-six SGA children (median age, 3.4 years) and 26 control children (median age, 3.8 years) were enrolled. Anthropometric, hematologic, biochemical, immunological, and endocrinological parameters were assessed at baseline and 1, 3, 6, 9, and 12 months after the start of GH treatment. As a result, median height SD score (SDS) of SGA children increased by +0.42 with 12-month GH treatment. Body mass index SDS was lower in SGA children than in controls. Serum apolipoprotein A1 increased, whereas apolipoprotein B decreased during GH treatment. Serum leptin and resistin levels, which were lower in SGA children than in controls at baseline, did not change remarkably with GH treatment. Monocyte counts, which were lower in SGA patients at baseline, increased after GH treatment. Neutrophil counts significantly increased after GH treatment. Natural killer cell ratios, which were higher in SGA patients, decreased after GH treatment. In conclusion, there was no evidence suggesting metabolic abnormalities in SGA children. Serum apolipoprotein changes might predict the beneficial role of GH treatment in lowering cardiometabolic risk. PMID- 29459554 TI - Effect of sodium glucose cotransporter 2 inhibitors on obstructive sleep apnea in patients with type 2 diabetes. AB - Obstructive sleep apnea syndrome (OSAS) is often associated with metabolic disorders such as obesity and type 2 diabetes and may contribute to cardiovascular events. A novel class of antidiabetic drugs, the sodium glucose cotransporter 2 inhibitors (SGLT2i) reduce body weight (BW), although there is limited data on their impact on OSAS. We therefore evaluated the effect of SGLT2i on OSAS in patients with type 2 diabetes. The presented study was a retrospective design in 18 patients with type 2 diabetes with OSAS (4 males, age range 39-81 yr) administrated a SGLT2i. HbA1c, BW, body mass index (BMI), blood pressure (BP) and apnea hypopnea index (AHI) were evaluated before and after SGLT2i administration. The relationships between the reduction in AHI and the other variables were examined using Pearson correlation analysis. We have got result that SGLT2i reduced AHI from 31.9 +/- 18.0 to 18.8 +/- 11.5 events per hr (p = 0.003). HbA1c, BW and BMI decreased significantly, whereas BP did not. The Pearson correlation analysis showed a significant relationship between the reduction in AHI and pre-administration of AHI. In conclusion, SGLT2i reduced not only HbA1c, BW and BMI but also AHI significantly and therefore has potential as an effective treatment of OSAS.

PMID- 29459556 TI - Concurrent variant type 3 autoimmune polyglandular syndrome and pulmonary arterial hypertension in a Japanese woman. AB - We describe a very rare case of concurrent variant type 3 autoimmune polyglandular syndrome (APS) and pulmonary arterial hypertension (PAH). A previously healthy 65-year-old Japanese woman was referred to our university hospital with a 2-month history of general fatigue and hyperglycemia. Laboratory tests revealed severe hyperglycemia (plasma glucose 543 mg/dL and HbA1c 10.7%) with ketonuria (3+). Glutamic acid decarboxylase (GAD) and IA-2 antibodies were positive, and the serum C peptide level was markedly decreased to 0.2 ng/mL. Accordingly, type 1 diabetes was diagnosed. Hashimoto's thyroiditis was also diagnosed because she had a diffuse goiter and a mild hypothyroidism (TSH 8.20 MUU/mL, and FT4 0.80 ng/mL) with positive autoantibodies for thyroid peroxidase and thyroglobulin. There was neither adrenal insufficiency nor hypocalcemia. In addition, chest X ray showed a suspicious PAH by a dilation of both pulmonary arteries, especially right descending artery, and right heart catheterization confirmed the presence of PAH. HLA Class II genotyping revealed DRB1-DQB1*0901 *0303, a common susceptibility haplotype in Japanese patients with type 3 APS or acute-onset type 1 diabetes. The combination of variant type 3 APS and PAH is extremely rare and to the best of knowledge, this is the first case reported in a Japanese patient.

PMID- 29459562 TI - [The impact of direct-acting antiviral therapy on the diagnosis of hepatitis-C virus-associated hepatocellular carcinoma]. AB - Since the introduction of direct-acting antiviral (DAA)-based combination therapies in September 2014 for patients with chronic hepatitis-C (CH-C), numerous patients have been diagnosed with hepatitis-C virus (HCV)-associated hepatocellular carcinomas (HCCs) during the screening performed prior to DAA therapy. The present study was conducted on the antiviral therapy for CH-C in two phases:i) the interferon (IFN) phase between January 2011 and August 2014 and ii) the DAA phase between September 2014 and September 2016. During the DAA phase, HCCs were detected in eight patients who were referred to our hospital for anti HCV therapy. In contrast, HCCs were detected in only two patients during the IFN phase. The number of patients with newly detected HCC in the DAA phase (20.5%) who were referred for the anti-HCV therapy was significantly higher than that in the IFN phase (1.7%). Owing to the high efficacy and safety of the DAA therapy, the number of patients referred to our hospital for anti-HCV therapy increased from 40.5 persons/year in the IFN phase to 80.3 persons/year in the DAA phase. The average ages of patients in the DAA and IFN phases were 68 and 61 years, respectively. The increase in the number of patients with newly detected HCC referred for the anti-HCV therapy in the DAA phase could be attributed to the increase in the number of referred patients for anti-HCV therapy and the aging of these patients in the DAA phase. All the eight patients with newly detected HCC who were referred for anti-HCV therapy in the DAA phase received curative treatments. The median age, rate of liver cirrhosis, and median tumor size of the patients were 69 years, 13%, and 16mm. Therefore, the findings of this study indicate that DAA therapies not only eradicate HCV infection but also contribute to the early diagnosis of HCC by encouraging the HCV-infected patients to visit hospitals and by promoting active network between hepatologists and family physicians.

AB - A 79-year-old man experiencing sudden abdominal pain was admitted to our hospital. Upper gastrointestinal endoscopy and computed tomography images revealed an 8-cm lesion, suggestive of submucosal tumor in the gastric antrum and a type 0-IIc early gastric cancer in the gastric body. The tumor ruptured during preoperative examinations, which necessitated emergency D1+ distal gastrectomy. Pathological findings confirmed the penetration of the gastric cancer into the submucosa. The cancer comprised well-differentiated tubular carcinoma cells with a low papillary structure. At the submucosa, small clusters of carcinoma cells were surrounded by clear spaces. These clusters displayed a characteristic "inside out pattern" on immunohistochemical examination, suggesting that the clusters were probably incipient lesions of invasive micropapillary carcinoma. The ruptured tumor was identified as a lymph node metastasis from the gastric cancer. We herein report this extremely rare case in which lymph node metastasis from early gastric cancer enlarged and ruptured. The findings of this study suggest that the characteristic pathological type identified in this report, which signified high-grade malignancy, was associated with the rupture. PMID- 29459564 TI - [Retention of patency capsule in a patient with Crohn's disease]. AB - A 40-year-old Japanese man with abdominal pain was referred to our hospital. The patient had been diagnosed with Crohn's disease at the age of 21 years and had since then received treatment with mesalazine and had been advocated an elemental diet. About 30 months before his visit to the hospital, he had swallowed a patency capsule, the retention of which in the ileum was subsequently detected on abdominal ultrasonography. The patient was advised to undergo the evaluation of stenosis, but he refused further investigation at that time. Computed tomography scanning performed at our institution revealed stenosis of the ileum and the presence of a high-density material in the proximal side of the stenosis. Double balloon enteroscopy and enterography with contrast media revealed multiple stenoses of the ileum. The stenotic ileum was surgically resected, and a foreign body was removed. Electron microscopy analysis revealed that the foreign body was the cellophane wall of the PillCamTM patency capsule. Thus, the retention of the cellophane wall of a patency capsule after consumption was diagnosed for the current case on the basis of the study findings.

Although abdominal computed tomography (CT), colonoscopy, and barium enema study indicated suspected duplication of the sigmoid colon, the exact portion of communication between the normal colon and the duplicated colon could not be determined. The patient was released, but followed up due to the lack of symptoms. After 7 months, she was urgently re-hospitalized due to the complaint of abdominal pain. Her abdominal CT revealed the wall thickness and distention of the duplication as well as voluminous stool containing barium. After the improvement of her symptoms and on the basis of the inflammatory findings, laparoscopic surgery was performed on the patient. Finally, the lesion was diagnosed as tubular- and continuous-type colonic duplication. Duplication of the colon is a relatively rare occurrence in adulthood. Herein, we report a case of duplication of the sigmoid colon diagnosed prior to surgery in an adult.

AB - A 53-year-old man was admitted to our hospital with the complaint of neck pain and dyspnea. His blood examination revealed increased C-reactive protein and amylase levels. Enhanced computed tomography (CT) images demonstrated a retropharyngeal and a mediastinal low-density area extending to the portal area. He was diagnosed with pancreatic pseudocyst from the abdominal cavity to the cervical region accompanied by spontaneous rupture into the portal vein. Endoscopic ultrasound-guided cyst drainage (EUS-CD) of the most inferior cavity around the superior mesenteric artery was performed through the gastric wall. No adverse events were recorded during the procedure, and a near-complete resolution of his symptoms and the pseudocyst was achieved. PMID- 29459567 TI - A Giant Cardiac Cavernous Hemangioma Involving the Left Atrial Roof in an Elderly Woman. AB - Cardiac tumors are relatively rare, with primary hemangiomas being a particularly rare benign neoplasm. Herein, we report a case of a symptomatic cardiac tumor detected via echocardiography in an 82-year-old woman. Although we performed advanced imaging examinations for her heart, we could not diagnose the tumor before surgery. Eventually, a tumor involving the left atrial roof was detected, and it was completely resected to relieve her symptoms and establish a precise diagnosis. Histopathological examination indicated a cardiac cavernous hemangioma. The patient exhibited an uneventful recovery without any complications. PMID- 29459568 TI - Endovascular Repair of an Abdominal Aortic Aneurysm with Iliac Vein Compression Syndrome. AB - An 84-year-old man with chronic obstructive pulmonary disease (COPD) was referred to our institution for further treatment of severe swelling of the left lower extremity. The left iliac vein was compressed by the abdominal aortic aneurysm and a right common iliac arterial aneurysm measuring 62 mm and 45 mm in diameter and was partially thrombosed. Multiple pulmonary artery embolisms were also noted. Endovascular repair of the abdominal aortic aneurysm and the right common iliac arterial aneurysm was performed because of his respiratory dysfunction. The left leg edema gradually resolved after endovascular treatment. Six months after the treatment, computed tomography (CT) demonstrated resolution of the venous thrombus of the left lower extremity. Although open surgery is reliable treatment for iliac compression syndrome, endovascular treatment might be a feasible and an adequate therapeutic option for patients who have severe comorbidities, complications, or high frailties. PMID- 29459571 TI - Venous Branching Pattern in a Patient with Hemorrhagic Infarction in the Lingula after the Upper Division Resection of the Left Lung. AB - BACKGROUND: Because left upper division resection is similar to right upper lobectomy, this procedure is frequently employed. Few studies have used the anatomic courses of veins evaluated on preoperative computed tomography (CT) imaging to determine what types of patients are at the highest risk for hemorrhagic pulmonary infarction. CASE: We describe our experience with a patient in whom hemorrhagic pulmonary infarction occurred at 6 days after transecting two superior branches (V1 and V3) of the three branches of the left superior pulmonary vein. We preoperatively confirmed that small-caliber lingular veins were perfused by V3. However, the patient had a poor pulmonary function, and the tumor was located distal to V3. Left upper division resection was therefore performed. CONCLUSION: The division of V3 could be the cause of hemorrhagic infarction in the lingular segment after upper division segmentectomy. PMID- 29459569 TI - Selection of a Surgical Treatment Approach for Aortic Coarctation in Adolescents and Adults. AB - PURPOSE: Coarctation of the aorta (CoA) in adolescents and adults is relatively rare. Several operative techniques for CoA in adolescents and adults have been reported, but there is still no consensus. This study aims to highlight the use of individual patient characteristics to select optimal treatment strategies for CoA in adolescents and adults. METHODS: Surgical repair of CoA was performed in five patients (mean age: 34 +/- 14 years, range: 13-58 years). All patients had primary CoA, and one had aneurysm above the CoA. One patient had undergone previous aortic valve replacement (AVR) and graft replacement of the ascending aorta. One patient underwent resection of the coarctation without cardiopulmonary bypass (CPB) followed by direct end-to-end anastomosis. Three patients underwent CoA resection with an interposition graft through a lateral thoracotomy with partial CPB. One patient underwent AVR with extra-anatomical bypass (ascending descending aorta). RESULTS: No in-hospital deaths occurred, and there were no complications. During the follow-up period, there has been no recurrence of CoA. CONCLUSION: CoA in adolescents and adults is associated with different issues from those encountered in infant patients, and comprehensive surgery should be performed in all cases. PMID- 29459570 TI - Loss of Muscle Mass is a Novel Predictor of Postoperative Early Recurrence in N2 Positive Non-Small-Cell Lung Cancer. AB - BACKGROUND: We often experienced early recurrence in patients with completely resected N2-positive non-small-cell lung cancer (NSCLC). Loss of muscle mass is a poor prognostic factor in patients with several stages of NSCLC. This study aimed to investigate the relationship between preoperative loss of muscle mass and postoperative early recurrence in patients with N2-positive NSCLC. METHODS: We retrospectively analyzed 47 male patients with completely resected pathological N2-positive NSCLC. Early recurrence was defined as that diagnosed within 1 year after the operation. We used the L3 muscle index (cross-sectional area of muscle at the L3 level, normalized for height) as a clinical measurement of loss of muscle mass (cutoff value, 52.4 cm2/m2). RESULTS: In all, 18 patients with early recurrence had significantly poorer outcomes compared with those without (P <0.01). In univariate analysis, loss of muscle mass (P = 0.023), carcinoembryonic antigen (CEA) level >5.0 ng/mL (P = 0.002), and absence of postoperative chemotherapy (P = 0.042) were predictors of postoperative early recurrence. In multivariate analysis, loss of muscle mass (P = 0.004) and CEA level >5.0 ng/mL (P = 0.001) were independent predictors. CONCLUSIONS: Loss of muscle mass is an independent predictor of postoperative early recurrence in pathological N2 positive NSCLC patients. PMID- 29459572 TI - A Rare Case of Multiple Myxoma Involving Both Mitral Valve Leaflets. AB - Mitral valve myxoma is a very rare entity. Multiple myxomas with extensive involvement of the anterior and posterior leaflets of the mitral valve are exceedingly rare. We report a 58-year-old man who was admitted as sudden syncope. Thoracic echocardiography showed several masses adherent to the anterior and posterior leaflets and the mitral annulus with obvious mobility. Intraoperative probing revealed multiple tumors attached to the mitral annulus, valve leaflets, and tendinous cords. Mechanical mitral valve replacement was performed. Histopathological examination confirmed all tumors to be myxomas. PMID- 29459573 TI - Potential Role of ASC, a Proapoptotic Protein, for Determining the Cisplatin Susceptibility of Lung Cancer Cells. AB - Primary lung cancer is the most frequent cause of cancer-related deaths worldwide. Cisplatin has been used as a key drug in the treatment for patients with lung cancer; however, most of the patients failed to respond to cisplatin within several months, and the mechanisms underlying the cisplatin resistance have not been fully elucidated. Apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC) is a key adaptor protein in the formation of inflammasomes. ASC is also involved in apoptotic signaling. Importantly, ASC expression is decreased in lung cancer and various cancers, but its precise function in tumor progression remains unknown. To explore the hitherto unknown role of ASC in lung cancer, we initially searched for lung cancer cell lines with higher expression levels of ASC using Cancer Cell Line Encyclopedia (CCLE) database, thereby identifying the A549 human non-small cell lung cancer cell line. Accordingly, with retroviral shRNA, the expression of ASC was forced to decrease in A549 cells. Stable ASC-knockdown cells, thus established, showed the increased activities of proliferation, motility, and invasion, compared with control cells. Importantly, ASC-knockdown cells also became resistant to cisplatin, but not to other anti-cancer agents, 5 fluorouracil and paclitaxel. Bcl-2 and phospho-Src levels were increased in ASC knockdown cells. A Bcl-2 inhibitor, ABT-199, induced an apoptotic response in ASC knockdown cells, and dasatinib, a Src inhibitor, blocked cell invasiveness. Thus, ASC may be involved in tumor suppression and cell death via Bcl-2 and pSrc. Targeting Bcl-2 and Src in ASC-downregulated populations of lung cancer may improve treatment outcome. PMID- 29459574 TI - Comparison of surgical outcomes after pneumonectomy and pulmonary function preserving surgery for non-small cell lung cancer. AB - BACKGROUND: According to previous reports, lobectomy with bronchoplasty or angioplasty is a more feasible surgery than pneumonectomy for central-type non small cell lung cancer. However, few studies have compared both the short- and long-term outcomes between pneumonectomy and pulmonary function-preserving surgery. METHODS: From January 2004 to December 2015, 18 patients underwent pneumonectomy (Group PN) and 12 patients underwent pulmonary function-preserving surgery (group PS) at Fukushima Medical University Hospital. Clinicopathological factors were statistically compared between the two groups. RESULTS: The operation times in Group PN and Group PS were 285.9+/-27.9 and 271.3+/-99.2 min, respectively (p=0.613), while the amounts of intraoperative bleeding were 324.8+/ 248.9 and 164.5+/-116.6 g, respectively (p=0.020). The duration of chest drainage and hospitalization after surgery in both groups were not significantly different but there was a tendency toward shorter periods of these durations in Group PS. The 5-year disease-free survival (DFS) rate in Group PN and PS was 51.4% and 74.1%, respectively, without a significant difference (p=0.298). The 5-year overall survival (OS) rate in Group PN and PS was 52.5% and 56.6%, respectively, also without a significant difference (p=0.748). The 5-year OS rate was inferior to the 5-year DFS rate in Group PS, and the 5-year OS rate was not better than the 5-year DFS rate in Group PN. CONCLUSIONS: The short-term results were better in Group PS than PN. However, the long-term results in both groups were similar. Other causes of death influenced OS in both groups; this result might have been affected by the surgical procedures. PMID- 29459575 TI - Difficult Stentablation with an Episode of Stuck and Entrapped Burr within the Underexpanded Stent. AB - Stentablation by rotational atherectomy has been reported as an option to correct underexpanded stents. Due to concerns of excessive stent damage, distal embolization of metal particles, excessive heat generation, and burr entrapment in the stent, stentablation has been considered the last choice to manage underexpanded stents. Here, we report a case of a stuck and entrapped atherectomy burr inside an underexpanded and undilatable stent, which made withdrawal of therotablation burr during rotational atherectomy difficult. After successful stentablation by rotational atherectomy, we were able to complete the percutaneous coronary intervention with another stent. PMID- 29459576 TI - A High Level of Blood Urea Nitrogen Is a Significant Predictor for In-hospital Mortality in Patients with Acute Myocardial Infarction. AB - High levels of blood urea nitrogen (BUN) have been demonstrated to significantly predict poor prognosis in patients with acute decompensated heart failure. However, this relationship has not been fully investigated in patients with acute myocardial infarction (AMI). We investigated whether a high level of BUN is a significant predictor for in-hospital mortality and other clinical outcomes in patients with AMI. The Japanese registry of acute Myocardial INfarction diagnosed by Universal dEfiniTion (J-MINUET) is a prospective, observational, multicenter study conducted in 28 institutions, in which 3,283 consecutive AMI patients were enrolled. We excluded 98 patients in whom BUN levels were not recorded at admission and 190 patients who were undergoing hemodialysis. A total of 2,995 patients were retrospectively analyzed. BUN tertiles were 1.5-14.4 mg/dL (tertile 1), 14.5-19.4 mg/dL (tertile 2), and 19.5-240 mg/dL (tertile 3). Increasing tertiles of BUN were associated with stepwise increased risk of in-hospital mortality (2.5, 5.1, and 11%, respectively; P < 0.001). These relationships were also observed after adjusting for reduced estimated glomerular filtration rate (estimated GFR < 60 mL/minute/1.73 m2) or Killip classifications. In multivariable analysis, high levels of BUN significantly predicted in-hospital mortality, after adjusting for creatinine and other known predictors (BUN tertile 3 versus 1, adjusted odds ratio [OR]: 2.59, 95% confidence interval [95% CI]: 1.57-4.25, P < 0.001; BUN tertile 2 versus 1, adjusted OR: 1.60, 95% CI: 0.94 2.73, P = 0.081). A high level of BUN could be a useful predictor of in-hospital mortality in AMI patients. PMID- 29459577 TI - Women among First Authors in Japanese Cardiovascular Journal. AB - The representation of women in Japanese academic medicine is not evident. We aimed to assess trends related to the proportion of female first authors in Japanese cardiovascular journals.We reviewed original research articles in 6 journals published in English by Japanese societies between 2006 and 2015 related to cardiovascular fields. We conducted a multivariable logistic regression analysis to assess the factors associated with the gender of first authors and plotted the trend of predicted probability for female first authors over the study period. Of 7,005 original articles, 1,330 (19.0%) had female first authors. Affiliations located in Japan (adjusted odds ratio [aOR], 0.76; 95% confidence interval [CI], 0.71-0.81), concurrent first and corresponding authors (aOR, 0.69; 95% CI, 0.64-0.74), and the total number of listed authors (aOR, 0.97; 95% CI, 0.95-0.99) were negatively associated with female first authors. The adjusted probability of a female first author increased from 13% to 20% on an average between 2006 and 2009, but the increase reached a plateau after 2010.Female first authors of original research articles published in Japanese cardiovascular journals increased over the examined decade. However, the representation of women is still low and has plateaued in recent years. A gender gap in authorship for Japanese cardiovascular journals remains. PMID- 29459578 TI - Trapping Balloon Technique for Removal of the Burr in Rotational Atherectomy. AB - Because rotational atherectomy (RA) has several unique complications, such as burr entrapment, vessel perforation, and slow flow, it is important for interventional cardiologists to be familiar with bailout procedures for such complications. The principal part of bailout procedures is to keep a guidewire in the target coronary artery during the procedure. However, it is not easy to keep a guidewire in the same position during the removal of a burr because the length of the RA guidewires is 300 cm, and the removal of a burr requires collaboration between the primary operator and an assistant. We describe the case of an 83-year old male with stable angina. We performed RA to the left anterior descending artery, and removed the burr using a KUSABI (Kaneka Medix Corporation, OSAKA, Japan) trapping balloon technique without activating the dynaglide mode. This simple technique would help RA operators remove a burr more reliably than the conventional removal technique. PMID- 29459579 TI - Neonatal Leukemoid Reaction with Fetal Inflammatory Response Syndrome Is Associated with Elevated Serum Granulocyte Colony Stimulating Factor and Interleukin-6. AB - Leukemoid reaction (LR) is a reactive disease that exhibits abnormal blood values similar to leukemia, but not due to leukemia. One report showed that neonatal LR (NLR) was associated with elevated serum granulocyte colony stimulating factor (G CSF) in only 30% of the study neonates. NLR is not always associated with the elevation of serum G-CSF. NLR was defined as a white blood cell count of >= 40 * 103/MUL and/or blast cell concentration of > 2%. We have focused on NLR with fetal inflammatory response syndrome (FIRS), defined as a fetal systemic inflammatory reaction triggered by intrauterine infection. FIRS was diagnosed based on a cord serum interleukin-6 (IL-6) concentration >= 17.5 pg/mL and histopathological chorioamnionitis. Because NLR is highly associated with FIRS, we have hypothesized that NLR is associated with the elevation of both G-CSF and IL-6. This is the first report to measure multiple cytokines in NLR at the same time. The study comprised 19 preterm infants with FIRS: 8 with NLR (study group) and 11 without NLR (control group). Serum G-CSF and IL-6 concentrations were significantly higher in the study group than the control group. There was a positive correlation between G-CSF and IL-6 levels in the study group but not in the control group. These results suggest that elevated serum G-CSF and IL-6 may underlie NLR. Thus, G-CSF and IL-6 concentrations may be predictive of the onset of NLR. Measuring these cytokines is useful for judging the prognosis of preterm infants and for their post-natal clinical management.

Axial velocity change rule of desktop slot exhaust hood can effectively provide the basis of the wind speed needed in order to control the poison. According to gas motion mathematical model, the geometry model and boundary conditions of desktop slot exhaust hood was established, and the influence of the hood sizes to axial velocity were analyzed by Fluent simulation. The changes of relationship between the axial velocity (V) and the distance from the hood mouth (L), the short edge of the hood mouth (a), the long edge of the hood mouth (b), the equivalent diameter of the hood mouth (d) and the square root of the hood mouth area (?A) were comparative analyzed by dimensionless processing. The result is the V/V0 with L/d have better change rule. The axial velocity change rule of different axial velocity were also analyzed using V/V0 with L/d change rule, and the change rule of V/V0 with L/d of desktop slot exhaust hood was obtained, which was verified by experiment. PMID- 29459581 TI - Predictors of Alcohol Relapse Following Liver Transplantation for Alcohol-Induced Liver Failure. Consideration of "A-D" Selection Criteria. AB - Demonstrated abstinence from alcohol for over six months and successful completion of a formal alcohol addictions program are two commonly employed criteria for determining whether an alcoholic patient with liver failure should proceed to liver transplantation. In this systematic review of the medical literature, we review the justification for these criteria and consider other variables that have also been reported to be of predictive value. While abstinence from alcohol for over six months is supported by the medical literature, data are more limited regarding the value of formal alcohol addictions program as selection criteria for proceeding towards liver transplantation. Positive family histories of alcoholism, co-inhabitants drinking alcohol in the presence of the patient and concurrent drug dependencies are more robust predictor variables of post-transplant recidivism. Based on the findings of this review, we propose a simple A-D transplantation selection criteria wherein "A" refers to demonstrated abstention from alcohol for over six months, "B" biology (a negative family history for alcoholism), "C", co-inhabitants not consuming alcohol in the presence of the patient; and "D", no concurrent drug dependency. PMID- 29459582 TI - Paeoniflorin Inhibits Receptor Activator for Nuclear Factor kappaB (RANK) Ligand Induced Osteoclast Differentiation In Vitro and Particle-Induced Osteolysis In Vivo. AB - BACKGROUND Paeoniflorin (PF), a glucoside isolated from the dried root of Paeonia lactiflora Pall, has been reported to have a number of pharmacological properties, including immunity-regulation, anticancer activities, and neuroprotective effect. However, PF's pharmacological role in bone disorder has been seldom reported. Hence, this study was designed to investigate the effects of PF on osteoclast differentiation and osteolysis diseases. MATERIAL AND METHODS The bone marrow macrophages were isolated from C57BL/6 mice and incubated with RANK ligand (RANKL) and various concentrations of PF. After 5 days of incubation, tartrate-resistant acid phosphatase (+) cells and bone resorption pits were counted. Effects of PF on expression of osteoclast-specific protein and gene were investigated via Western blot, q-PCR, and immunofluorescence assay. The osteoprotective effect of PF in vivo was evaluated in a calvarial osteolysis model via micro-CT scan and histological stain. RESULTS In vitro, PF intervention inhibited osteoclast formation and resorption activity. PF also impaired RANKL induced NF-kappaB phosphorylation and immigration to the nucleus. PF suppressed osteoclast-marker protein and gene expression. In vivo, PF inhibited cobalt chromium-molybdenum alloy particle-induced osteolysis and reduced osteoclast number in tissue slice. CONCLUSIONS PF is a potential agent against osteolysis related diseases caused by excessive osteoclast activity.

AB - In the present study hemoglobin concentration were estimated in chronic kidney diseased patient to observe the frequency of low hemoglobin level in chronic kidney diseased (CKD) patient and to assess the incidence of anaemia. This cross sectional study was carried out in the department of Physiology of Mymensingh Medical College, Mymensingh, Bangladesh from July 2014 to June 2015. For this purpose, total 200 subjects with age ranged from 25 to 60 years were selected and divided into100 healthy persons as control group and 100 CKD patients as study group. Both control and study group were further divided into 50 male and 50 female. Hemoglobin concentration was evaluated by the Cyanmethemoglobin (CMG) method. Statistical analysis of data was done by unpaired student's 't' test. The results showed that hemoglobin levels decreased significantly in chronic kidney diseased patients than the normal healthy persons. The decreasing frequency of hemoglobin level in CKD may predispose the patients to anemia and increasing the other complications. PMID- 29459585 TI - Ultrasonographic Evaluation of Malignant Pediatric Abdominal Tumour with Histopathological Correlation. AB - Ultrasonography is a very useful diagnostic tool to evaluate pediatric abdominal mass. This cross sectional study was conducted among clinically suspected patients having malignant abdominal mass attending in the department of Radiology & Imaging, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from January 2008 to December 2009. Total 56 patients were included in this study. Patients were scanned by high resolution gray scale ultrasonography of the abdominal masses. After surgical procedure, biopsy specimen were collected in a container containing 10% formalin and sent for histopathological examination. Mean age of the patients group was 5.91 years with a standard deviation of +/ 3.21 years. All patients were within 2 to 13 years age. Out of all patients, male were 33(58.9%) and 23(41.1%) were female. Male and female ratio was 1.4:1. Ultrasonographic diagnosis as Wilm's tumour were 27(48.2%), hepatoblastoma 8(14.3%), lymphoma 7(12.5%), neuroblastoma 6(10.7%), suspected malignancy 6(10.7%) and lastly teratoma were 2(3.6%). Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of ultrasonography in the evaluation of Wilm's tumour were 100.0%, 90.6%, 88.9%, 100.0% and 94.6% for neuroblastoma 83.3%, 98.0%, 83.3%, 98.0% and 96.4% for lymphoma 83.3%, 96.0%, 71.4%, 98.0% and 94.6% and for hepatoblastoma 100.0%, 100.0%, 100.0%, 100.0% and 100.0% respectively. It is a noninvasive and cost effective modality. Carefully performed ultrasonographic study would give reliable and accurate information needed in the diagnosis of abdominal malignancy in children.

AB - BACKGROUND Cystic artery pseudoaneurysm is rare, and some cases are associated with inflammation of the gallbladder. There is limited information regarding this condition, and the clinical features remain unclear. This report is a case of ruptured cystic artery pseudoaneurysm diagnosed by computed tomography (CT) imaging and treated with urgent cholecystectomy and is supported by a literature review of previous cases. CASE REPORT A 90-year-old man, who had developed acute cholecystitis due to a gallstone one month previously, was referred to our hospital. He developed fever and epigastric pain while waiting for a scheduled elective cholecystectomy. Laboratory investigations showed elevated markers of inflammation and elevated hepatobiliary enzyme levels. Computed tomography (CT) imaging showed cholecystitis and pseudoaneurysm of the cystic artery. The pseudoaneurysm had ruptured and was accompanied by the formation of a hematoma within the gallbladder that involved the liver bed. Having made the preoperative diagnosis, an urgent open laparotomy was performed, during which the gallbladder was found to have perforated. The hematoma penetrated into the liver bed. Cholecystectomy was performed, and the pseudoaneurysm of the cystic artery was extirpated. There were no serious postoperative complications. A literature review identified 50 previously reported case of cystic artery pseudoaneurysm. CONCLUSIONS A case of ruptured cystic artery pseudoaneurysm, successfully treated with urgent cholecystectomy is reported, supported by a literature review of previous cases and characterization of the clinical features of this rare condition. PMID- 29459586 TI - Risk Factors and Immediate Neonatal Outcome of Multiple Pregnancies in a SCANU of A Tertiary Care Hospital, Bangladesh. AB - Multiple pregnancies are a significant risk factor for maternal and perinatal morbidity due to inherent biological risks. The present study was aimed to determine the risk factors and to evaluate the immediate neonatal outcome of multiple pregnancies. This descriptive observational study was conducted in the newly established Special Care Neonatal Unit (SCANU) of Mymensingh Medical College Hospital (MMCH), Bangladesh from January 2015 to March 2015. Total 86 newborns of multiple pregnancies who were admitted during the study period were included in the study. Among them 34 pairs were twin, and 6 sets of triplets were present. Among all infants in the study 79.1% were twin and 20.9% were triplet. According to our observation most of the mother aged between 20-29 years (67.5%) and majorities of them were multi-para (62.5%). Preterm delivery occurred in 70.0% cases. 75% newborns were delivered by caesarian section and remaining by vaginal route. The most common risk factors in present study are use of ovulation induction drugs (52.5%) for sub fertility followed by family history of multiple gestations. In 35.0% cases we did not find any cause. Common morbidities of the infants were preterm low birth weight (95.3%), neonatal jaundice (81.3%), RDS (34.8%), perinatal asphyxia (PNA) (17.4%), neonatal sepsis (25.0%) and congenital anomalies (23.2%). Mortality rate of twin was 30% and for triplets it was 50%. Among total study population mortality rate was 30.2%. Main causes of mortality was preterm low birth weight (76%), RDS (57.6%), septicaemia (26%), PNA (19.0%). Morbidities and mortalities in infants of multiple pregnancies are observed much higher than singleton pregnancy. We hope that in light of our findings regarding risk factors like assisted reproduction and their consequences over mother and newborn, periodic reviews will be done in future to reduce the incidence and the unfavourable outcome of multiple pregnancy.

AB - Chronic kidney disease (CKD) is an international health problem affecting 5-10% of the world population. Patients with chronic kidney disease were known to have higher prevalence of changes in serum calcium, phosphate and parathyroid hormone in Western countries, but data on the impact of CKD on serum calcium, phosphate and parathyroid hormone in our country are scarce. This cross-sectional type of descriptive study was conducted in the Department of Medicine, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from March 2016 to September 2016. The aim of this study is to estimate serum calcium, phosphate and parathyroid hormone levels in chronic kidney disease (CKD) patients for early recognition of abnormalities, understanding of their patho-physiological consequences & planning management strategies to prevent their progression, thus reducing the morbidity & mortality. This study shows Hypocalcemia, hyperphosphataemia and elevated serum PTH levels are noted in later CKD stages & worsen with disease progression. PMID- 29459588 TI - Magnetic Resonance Imaging in Evaluation of Sinonasal Masses with Histopathological Correlation. AB - Sinonasal mass is the abnormal growth of tissue from nasal cavity and mucosa of the paranasal sinuses. The growth may be benign or malignant. The benign lesion grows slowly and does not metastasize. The malignant lesion grows rapidly and metastasizes early. The aim of this study is to evaluate and diagnose the various types of sinonasal masses with MRI and its correlation with histopathological findings. This cross sectional descriptive study was carried out for a period of 02 years, from July 2015 to June 2017. The patients were selected from the ENT outpatient department and from the department Radiology & Imaging of Mymensingh Medical College Hospital, Mymensingh, Bangladesh who were reported as case of sinonasal masses. Thirty three (33) patients (17 males and 16 females) with sinonasal masses were included after fulfilling exclusion & inclusion criteria which was confirmed by proper clinical examination & were subjected to MRI and histopathological examination. The age range was 11 to 85 years. The nasal cavity was the most commonly involved site with sinonasal malignancies (were 4 cases, 12.12%) followed by the maxillary sinuses (were 2 cases, 6.06%). The least commonly affected site was the frontal sinuses (was 1 case, 3.03%). Histopathological findings shows benign sinonasal tumors were present in 25 cases. The most common benign lesion was sinonasal polyposis 10 cases (30.30%), followed by inverted papilloma 6 cases (18.18%) & juvenile nasopharyngeal angiofibroma 6 cases (18.18%), adenoma 02 cases (6.06%), and one case was rhinosporidiosis (3.03%). Malignant sinonasal tumors were present in 8 cases. Most common malignant tumors were nasopharyngeal carcinoma in 4 cases (12.12%), adenoid cystic carcinoma in 3 cases (9.09%) and non-Hodgkin lymphoma was present in 01 case (3.03%). MRI report shows benign masses in 23 cases of which nasopharyngeal polyposis was 10(30.30%), inverted papilloma 6(18.18%), juvenile angiofibroma 4(12.12%), adenoma 02(6.06%) & rhinosporidiosis 1(3.03%). Among 10 malignant tumors nasopharyngeal carcinoma were 6(18.18%), adenoid cystic carcinoma 3(9.09%) & non-Hodgkin lymphoma 1(3.03%). MRI findings of malignant sinonasal masses revealed that sensitivity 87.5%, specificity 40.0%, positive predictive value (PPV) 70% & negative predictive value 66%. Statistically significant association was observed between histopathology & MRI findings, p value was 0.305. Statistically significant association was found between histopathology & MRI findings. PMID- 29459589 TI - Interaction between Hypertension and Asthma in Adult. AB - Asthma has been defined as a chronic inflammatory disorder of the airways that is associated with recruitment of inflammatory cells and the clinical development of wheezing, shortness of breath, chest tightness, and cough. The prevalence of asthma increased steadily over the latter part of the last century, first in the developed and then in the developing world. Current estimates suggest that asthma affects 300 million people worldwide, with a predicted additional 100 million people affected by 2025. This cross sectional study was conducted from January 1999 to August 1999 on 5642 Bangladeshi people and another same study carried out from November 2009 to April 2010 on 8088 subjects. In 1999 the prevalence of asthma was 6.9% whereas in 2010 it is 6.96%. Both asthma and hypertension are spastic disorders of smooth muscle, there is the similarities between these two diseases may predispose the individuals with one disease to the other. This descriptive type of cross-sectional study was done to find the Interaction between hypertension and asthma in adult and carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from July 2014 to January 2016. Fifty (50) male and fifty (50) female adult asthmatic patients aged 18-60 years were included in the study group. They are enrolled from the Department of Medicine, Mymensingh Medical College, Mymensingh and also from locality. For comparison age matched 50 male and 50 female apparently healthy persons were also studied as control. Blood pressure was estimated by auscultatory method by sphygmomanometer. For statistical analysis unpaired student's 't' test was used. Mean blood pressure were significantly increased in study group in comparison to control group and the result was statistically significant (p<0.001). The study findings showed a high prevalence of hypertension among asthmatic patients than non asthmatic healthy persons. From this study, it may be concluded that hypertension and asthma are closely connected. PMID- 29459590 TI - Skin Biopsy and Histopathological Diagnosis of Dermatological Diseases. AB - Microscopic examination of skin and mucous membrane is an established investigation in diagnosis and follow up of many dermatological conditions frequently encountered during practice. Histopathological examination is performed with biopsied specimen from skin and or mucous membrane where required. However neither do all skin biopsies produce neither a conclusive diagnosis nor the dermatologists routinely perform this procedure to every patient they consult. This cross sectional descriptive study conducted by reviewing the records of all biopsied cases studied for histopathology in Mymensingh Medical College, Mymensingh and Shaheed Mansur Ali Medical College, Dhaka, Bangladesh from January 2012 to December 2016. The aim of this study was to investigate the favourable clinical diagnoses set by dermatologists when performing skin biopsy, the diagnoses reached by the dermatopathologists after microscopic examination, and the relationship between them and finally to comment on the instances that skin biopsy fails to fulfill the diagnostic task. Fourteen hundred and thirty six (1436) cases of skin biopsy were reviewed and descriptive statistics were performed. Maximum cases 39.1% (562) were in 2nd decade with almost equal sex distribution. The most frequently proposed clinical diagnoses included papulosquamous dermatoses 28.6% (410), whereas histological confirmation was in 13.1% (188). Histological diagnosis was more as nonspecific dermatitis 31.6% (454). After microscopic examination, a specific histological diagnosis was found in 83.5% (1199) of the cases and a consensus between clinical and histological diagnoses was observed in 69.2% (994). Neither histological diagnosis nor any feature consistent with clinical suspicion was observed in 10.1% (145) cases. Histopathological examination of skin biopsy is still a valuable diagnostic tool in many skin diseases and dermatoses with diagnostic dilemma. There are cases in which diagnostic inefficiency are being faced even after skin biopsy examination. PMID- 29459591 TI - Correlation of Ball Circumference with Body Weight in 5-10 Years Aged Bangladeshi Children. AB - This cross sectional, descriptive and analytic study was conducted among 5-10 years aged 109 Bangladeshi children (70 male and 39 female) at different areas of Mymensingh district (Fulpur, Muktagacha, Fulbaria, Trisal and Haluaghat), Bangladesh from January 2016 to December 2016. Sample collection was done by nonrandom purposive sampling technique. Any kind of congenital and acquired foot deformity was excluded to construct standard measurement. The present anthropometric study was designed to construct data of 5 to 10 years aged Bangladeshi children regarding ball circumference, to measure its correlation with body weight and this attempt has been made out to grow interest among the researchers for future study and also to compare the data with the data of the people of other races. Weight of the subject was measured with the digital weighing machine and ball circumference was measured using flexible measuring tape. The children were asked to stand with weight distributed equally on both feet. The legs were perpendicular to the feet. The mean ball circumference of right side of 5, 6, 7, 8, 9 and 10 years aged male were 16.93+/-1.05cm, 17.00+/ 0.72cm, 18.10+/-1.28cm, 18.33+/-.99cm, 19.37+/-1.12cm and 19.94+/-1.30cm respectively and those of female were 16.27+/-1.10cm, 16.85+/-0.59cm, 17.44+/ 0.92cm, 18.02+/-0.82cm, 18.00+/-1.58cm and 19.23+/-1.40cm respectively. The mean ball circumference of left side of 5, 6, 7, 8, 9 and 10 years aged male were 16.86+/-1.05cm, 16.94+/-.70cm, 18.02+/-1.29cm, 18.26+/-.99cm, 19.27+/-1.12cm and 19.87+/-1.29cm respectively and those of female were 16.18+/-1.10cm, 16.77+/ 0.62cm, 17.36+/-0.92cm, 17.98+/-0.87cm, 17.90+/-1.58cm and 19.13+/-1.40cm respectively. In this study on both sides, ball circumference showed non significant positive correlation with body weight in 5 years old male and female, 6 years old male and female, 7 years old male and female, 8 years old female, 9 years old male and female and 10 years old male and female. In case of 8 years old male, it showed non-significant negative correlation with body weight. PMID- 29459592 TI - Current Trends of Using Systemic Antifungal Drugs and their Comparative Efficacy in Tinea Corporis and Tinea Cruris in Outpatient Department of Dermatology in a Tertiary Level Hospital. AB - Tinea corporis & cruris are one of the earliest known fungal infection and are very common throughout the world. Although tinea corporis and tinea cruris does not cause mortality but causes morbidity and poses a major health problem. This study was conducted to evaluate the Comparative Efficacy of Terbinafine and Fluconazole in the Treatment of Tinea corporis and Tinea cruris. This cross sectional comparative type of analytical study was carried out at the department of Pharmacology & Therapeutics with collaboration of Dermatology and Venereology in Mymensingh Medical College Hospital, Mymensingh, Bangladesh from January 2016 to December 2016. In this study 168 newly diagnosed Tinea corporis and Tinea cruris patient was purposively selected where pattern of comparative efficacy of terbinafine and fluconazole were analyzed. Among 168 patients most of the patients presented with tinea corporis (58.33%). Most patients belong to 21-30 years age group. Male female ratio in this study was 1.15:1. In this study 143 patients were treated by fluconazole 50mg once daily for 4 weeks and 25 patients were treated by terbinafine 250 mg once daily for 4 weeks. After 4 weeks, improvement rate by fluconazole was 86.02% and terbinafine 96.00%. The clinical score of both groups after 4th week of treatment, there was slight more reduction of clinical score in terbinafine using group than fluconazole using group. The difference between these two clinical score was not statistically significant (p>0.05). Although no significant difference was observed between these two groups of patient in clinical aspect, but due to its lower price and availability in the hospital, it is suggested that fluconazole is more suitable for the treatment of tinea corporis and tinea cruris. PMID- 29459593 TI - A study on the Effect of Captopril on Gentamicin Induced Nephrotoxicity in Rats. AB - An experimental study was carried out to evaluate the effect of Captopril on Gentamicin induced nephrotoxicity in rats in the Department of Pharmacology, Mymensingh Medical College and Dhaka Medical College, Bangladesh. Gentamicin antibiotic is most commonly employed clinically because of their potent bactericidal activities against Gram negative bacterial infections, less bacterial resistance, post-antibiotic effects and low cost. Gentamicin is associated with an induction of slow rises in serum creatinine, inflammation and perivascular edema, tubular degeneration and necrosis, tubular debris collection, glomerular atrophy which ultimately show the way to renal dysfunction. In spite of continued attractive efforts during the last decade, antioxidants like medicinal plants and different classes of drugs which were promised to reduce or ameliorate Gentamicin induced nephrotoxicity is yet a matter of debate. This study was aimed at inducing nephrotoxicity by injection Gentamicin and estimating the renal damage biochemically by measuring serum creatinine and perform histopathology of renal cortex in support of biochemical findings both in control groups, nephrotoxic and Captopril treated rats; also to determine the comparison between the concomitant and post effects of Captopril on control and nephrotoxic rats and to estimate the effect of Gentamicin withdrawal, 7 days after last injection in rats. PMID- 29459594 TI - Evaluation of Intraoral Burning Sensation in Response to Heat-Cured and Self Cured Acrylic Resin Denture Base Material. AB - The objective of this prospective experimental clinical trial was to evaluate intraoral burning sensation in response to heat-cured and self-cured acrylic resin denture base material and carried out in the department of Prosthodontics of Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from February 2014 to September 2015. Forty eight patients were evaluated in this study; of them 35(72.92%) patients were male and 13(27.08%) patients were female with age range from 24 to 70 years. In this study 48 patients were evaluated in term of burning sensation, of them 24 patients were provided with heat-cured acrylic resin denture and were considered as Group A and 24 patients were provided with self-cured acrylic resin denture and were considered as Group B. In Group A 14(58.4%) at 1st week, 2(8.4%) at 1st month, 10(41.8%) at 3rd month and 5(21.0%) at 6th month developed burning sensation. On the other hand the values were 18(75.0%), 22(91.6%), 14(58.2%) and 2(8.4%) at 1stweek, 1st month, 3rd month, and 6th month respectively. Chi-square test was done for statistical analysis and p value was <0.05. So, results were statistically significant. PMID- 29459595 TI - Distribution, Management Difficulty and Outcome of Branchial Anomalies. AB - Branchial arch anomalies are one of the most common congenital anomalies of the neck. Developmental anomalies of the branchial apparatus account for 17% of all pediatric cervical masses. This study aimed to focus on proper diagnosis of branchial anomaly and describe occurrence, presentation, management and outcome of usual and unusual types. This ten-year prospective observational study was conducted from November 2005 to November 2015 including 2-year postoperative follow-up of the patients in Department of ENT, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. Total 89 patients were enrolled for this study. Information was recorded on Clinical examination, relevant investigation, Per-operative findings and Histo-pathological findings. After receiving Histo pathological findings 61 cases were proved as branchial arch anomalies. Ultrasonography and Histopathology was done for every patient. Fistulogram and sinogram was done for patient of fistula and sinus respectively. CT scan was needed for 9 patients, MRI for 3 patients and 12 patient undergone FNAC. Outcomes of those patients were described in terms of Hospital stay, Complications and Follow up studies. Data analysis was done by Standard Statistical Method.Presentation of a number of participant's mimics Branchial arch anomalies; 4.91% was syndromal. Second branchial arch anomalies were the highest. Management was exclusively surgical. Recurrence rate was about 6.56%. Surgery is the tool for diagnosis, treatment, preventing complications, avoiding carcinoma for branchial arch anomalies. PMID- 29459596 TI - Irritable Bowel Syndrome: Prevalence and Dietary Factors in the Sylhet District of Bangladesh. AB - Irritable bowel syndrome (IBS) is a common functional bowel disorder. Along with other factors diet plays an important role in the causation of IBS. This population-based study was done to find out the prevalence of IBS and to find out the dietary factors associated with IBS from August 2011 to December 2011 in Sylhet district of Bangladesh. Nineteen hundred apparently healthy subjects selected by cluster sampling methods were interviewed by a validated bowel disease questionnaire. Dietary history of the subjects was also taken. Irritable bowel syndrome was diagnosed according to Rome III criteria. The prevalence of IBS was found 14.2% (n=269, M=15%, F=13.4%, p=0.365). Mean age of the IBS patients were higher than the study population (41.35 years vs. 34.74 years, p=0.000). Irritable bowel syndrome was found more in low education group (16.3%) with lower socioeconomic status (16.5%) and in single person (16.7%). IBSD was the most prevalent subtype (48.7%), IBSM was the next common subtype. Abdominal pain relieved by defecation (81%) and abdominal pain associated with loose stools (81%) were the two commonest symptoms. Age (OR 1.023, p=0.000), less intake of meat (OR 2.281, p=0.000) and pulses (OR 1.648, p=0.001) and more intake of tea (OR 1.524, p=0.009) and spices (OR 0.452, p=0.000) were found as independent predictor of IBS. Irritable bowel syndrome is a common disorder in our community. IBSD is the most prevalent subtype. Less intake of meat, pulses and more intakes of tea and spices are important associated factors for IBS. PMID- 29459597 TI - Prevalence of Metallo-beta-lactamase Producing Non-fermentative Pseudomonas Species from Clinical Isolates in Dhaka, Bangladesh. AB - Antimicrobial drug resistance, a global concern, has been increasing unpredictably in microorganism causing human infections specially among Gram negative non-fermenting Pseudomonas spp. Carbapenems, a beta lactam antibiotics, are the most potent and effective drug usually kept reserved for treating the multi-drug resistant Psedomonas spp and other infections caused by organisms producing Extended Spectrum Beta Lactamase (ESBL) and AmpC. Clinical utility of carbapenem will reduce when resistant bacteria evolve due to production of carbapenem hydrolyzing Metallo-beta-lactamase (MBL) which confers high-level resistance to all beta-lactam antibiotics except aztreonam. The various reports on the prevalence of MBLs are available from many countries but few from Bangladesh. We investigated the prevalence of MBL production in these Pseudomonads obtained from clinical sources in an uraban setting in Dhaka, Bangladesh. A total of 29,136 specimens were processed for culture from January 2011 and December 2015 from non duplicated patients attending diagnostic unit of icddr,b from different settings of Bangladesh. The specimens included urine 14,323; blood 11,378; other body fluid 2,487; sputum 535 and tracheal aspirate 413. All specimens were processed for culture following standard bacteriological methods and the Pseudomonas spp were identified following defined standard biochemical procedures. Metallo-beta-lactamase (MBL) was determined by EDTA disk synergy (EDS) test. Antimicrobial susceptibility test was performed by disk diffusion method and susceptibility pattern was interpreted and reported following Clinical Laboratory Standard Institute (CLSI) guideline. From 29,136 specimens a total of 2,340(8%) were isolated and identified as Pseudomonas spp. Of the identified Pseudomonas spp, 238(57.6%) were from tracheal aspirate, 216(40.4%) from sputum, 902(36.7%) from other body fluids, 463(4.1%) from blood and 521(3.6%) from urine samples. From 2,340 Pseudomonas spp, by selective sampling, imipenem-meropenem resistant and intermediate susceptible 100 strains were tested for MBL production and 92 were found positive. Tracheal aspirate showed 38%, other body fluids 30%, Urine 17%, sputum 4% and blood 3% MBL production respectively. Irrespective of the sources of specimens, Pseudomonas spp showed 71% resistance to cefixime, 70% to ceftriaxone, 64% to gentamicin, 56% to piperecillin+tazobactam, 50% to ciprofloxacin, 49% to amikacin, 46% to netilmicin, 45% to ceftazidime, 30% to meropenem, 26% to imipenem and 19% to polymyxin B. As multi-drug resistant Pseudomonas showed high level of (92%) MBL production, so MBL detection testing facility may be a useful battery to determine MDR producing Pseudomonas from clinical isolates. PMID- 29459598 TI - Abandonment and Outcome of Childhood Acute Myeloid Leukemia in A Tertiary Level Hospital. AB - Acute leukemias are the most common child hood malignancy, of which acute myeloid leukemia (AML) are 15 to 20%. Abandonment is one of the most important causes of treatment failure in AML in developing countries. Lost to follow-up is also a big problem in low income countries. Many patients stop therapy soon after diagnosis due to cost, distance and ignorance. To determine the abandonment, outcome and treatment related mortality (TRM) and morbidity among children with AML. This prospective observational study was conducted in the Department of Pediatric hematology and Oncology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka from February 2013 to January 2014. Fifty (50) patients of AML visited to out patient department (OPD) of Pediatric hematology and Oncology. Among them 11(22%) patients refuse treatment from outdoor. Thirty nine (78%) patients of AML were selected as per inclusion and exclusion criteria. After proper evaluation and clinical examination of these patients, CBC and Bone marrow examination was done for confirmation of diagnosis. A total of 39 patients were recruited in this study. Seventeen (43.6%) patients were male and 22(56.4%) were female. Mean+/-SD of age was 7.80+/-4.42 years and range was 1 year to 18 years. Out of 39 patients, 18(46.1%) patients were abandoned, 15(38.4%) expire, relapse 2(5.2%) & alive 4(10.3%). High abandonment (46.1%) and treatment related toxic death (38.4%) has compromised the outcome of acute myeloid leukemia. However AML can be treated with better outcome if improved the supportive care, reduce toxic death, refusal or abandonment. PMID- 29459599 TI - Erythrocyte Glucose-6-Phosphate Dehydrogenase Level in Type 2 Diabetes Male. AB - The patient with diabetes mellitus (DM) and its complication is increasing in our country and all over the world. There is also significant increase in the prevalence of erythrocyte glucose-6-phosphate dehydrogenase (eG6PD) deficiency in the men with longer duration of diabetes mellitus. To assess the eG6PD in type 2 diabetes male subjects to observe their enzyme status. This cross-sectional study was conducted in the Department of Physiology, Dhaka Medical College, Dhaka, Bangladesh from January 2011 to December 2011. Sixty male subjects with type 2 diabetes mellitus were selected with the age ranging from 40 to 60 years. Out of diabetic subjects, 30 (thirty) were with controlled (B1) and other 30 (thirty) with uncontrolled (B2) type 2 diabetes mellitus were selected from Outpatient Department of BIRDEM Hospital by random basis. And 30 age-matched, healthy non diabetic male subjects were considered as control group for comparison. Erythrocyte G6PD level was measured by spectrophotometric method. Fasting Blood Glucose (FBG), HbA1c were measured by standard laboratory techniques in the laboratory of BIRDEM and Armed Forces Institute of Pathology (AFIP), Dhaka Cantonment, Dhaka. For statistical analysis unpaired Student's 't' test was performed. The result was expressed as Mean+/-SD among the groups. In this study, eG6PD level was significantly lower in both the study groups. This study concludes that eG6PD level decreases in male with diabetes mellitus. PMID- 29459600 TI - Comparative Study of Patellar Tendon Graft versus Hamstrings Graft for Anterior Cruciate Ligament Reconstruction. AB - Graft selection for primary anterior cruciate ligament reconstruction is very important part of knee stability. The purpose of this Qasi experimental study was to compare the clinical outcomes after ACL reconstruction using either a BPTB graft or a four-strand hamstrings graft and conducted from January 2012 to December 2013. Patients presented with a symptomatic unilateral ACL rupture who were underwent ACL reconstruction by using either BPTB or Hamstrings graft, IPD of Department of Orthopedics at Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka as well as in a private hospital in Dhaka, Bangladesh were selected as study population. Patients were divided into Group A who were treated with the patellar tendon bone graft and Group B patients who were received hamstrings tendon graft. All surgery was performed by the same surgeon and the both procedures were arthroscopically assisted. Operation was performed at least three (03) weeks after initial trauma. All patients were assessed by independent examiner before surgery, at 6 months, 12 months and then annually by clinically. A total number of 70 patients were recruited for this study. The mean age with SD of Group A and Group B were 27.31+/-10.91 and 26.97+/-10.10 years respectively (p=0.892). Tegner scores were measured preoperatively and post-operatively. The score were 2.2+/-1.1 and 2.1+/-1.0 in preoperatively (p=0.817). In post operatively the mean score were 6.0+/-1.7 and 5.8+/-1.5 in Group A and Group B respectively (p=0.508). Regarding outcome of the operation excellent was 18(51%) cases in both Group A and Group B, good was 15 (43%) and 16(46%) cases in Group A and Group B respectively (p=0.793). In conclusion there was no significant difference between the two groups of the ACL reconstructions cases. PMID- 29459601 TI - Age Related Variation in the Number of Endometrial Gland in Bangladeshi Cadaver. AB - This cross-sectional descriptive study was done to see the variation in the number of endometrial gland in Bangladeshi cadaver in different age groups to find out the anatomical variation and to compare it with other study findings. For this purpose 30 post mortem specimens containing female genital organs particularly uterus were collected by purposive sampling technique from cadavers of different age groups. All the collected specimens were fixed in 10% formalin solution. This study was carried out in the department of Anatomy, Mymensingh Medical College from July 2006 to June 2007. After dissection of specimen, microscopic study was done to count the number of the endometrial glands. Mean+/ SD numbers of gland per square mm area were 5.88+/-1.56, 14.75+/-6.90, and 7.35+/ 1.79 in age Group A (2-12 years), B (13-45 years) & C (46-80 years) respectively. Highest number of gland was seen in Group B (5.66 to 22.48 per sq mm) & lowest number of gland was seen in Group A (3.30 to 9.95 per sq mm). The present study findings were compared with that of the references. PMID- 29459602 TI - Pattern and Extent of Tricuspid Valve Involvement in Chronic Rheumatic Heart Disease. AB - Rheumatic heart disease causes a significant number of morbidity and mortality in Bangladesh. Although the mitral and the aortic valve are the two most involved valves in rheumatic heart disease, the tricuspid valve disease is not uncommon secondary to, or in association with, mitral or aortic valve disease, but receives less attention as compared to the primary left-sided valve disease. Appropriate treatment of the tricuspid valve disease may improve long-term functional outcome. But the pattern and extent of the tricuspid valve involvement was not studied recently. This study was carried out to observe the pattern and extent of tricuspid valve involvement in Rheumatic Heart Disease patients. This observational analytical study was undertaken in the department of Cardiology, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from December 2010 to September 2011. Considering all ethical issues, data were collected from 173 subjects who underwent Echocardiography for their Chronic Rheumatic heart disease. Pattern of tricuspid valve involvement was observed by using Transthoracic Echocardiography by 2D, M mode and Doppler assessment. One hundred seventy three (173) patients with Rheumatic Heart disease was studied, out of these, 36 patients had evidence of tricuspid valve involvement based on echocardiographic findings. Fifteen (15) patients had Tricuspid stenosis and 36 patients had Tricuspid Regurgitation in the patients with TV involvement. All the patients with TV involvement had thickened leaflets. Doming, restriction of motion and calcification were present in different proportions. From this study, it can be concluded that organic tricuspid valve involvement in RHD is not uncommon in our country.

AB - The purpose of this study was to investigate magnitude, pattern and involvement of previously unheralded coronary artery disease in patients suffering from clinically significant peripheral artery disease of lower limbs. This cross sectional study was carried out in National Institute of Cardiovascular Diseases, Dhaka, Bangladesh from January 2014 to February 2015. Total 58 patients with clinically diagnosed peripheral arterial disease of lower limb undergoing angiographic evaluation. Selective CAG in addition to peripheral arteriography was performed in all the study population as per ACC/AHA guidelines for CAG (class IIa recommendation).In this study, it was documented that the proportion of coronary arterial disease was highest in LAD (63.9%) followed by LCX (55.6%), RCA (52.8%), and lowest LM (11.1%) in lesion with aorto-iliac segment. But the proportion of coronary arterial disease was highest in LCX (41.9%) followed by LAD (38.7%), RCA (35.5%), and lowest LM (12.9%) in lesion with femero-popliteal blood vessels. Similarly, the proportion of coronary arterial disease was highest in LCX (36.4%) followed by RCA (27.3%) and equal percentage in LAD and lowest in LM (9.1%) in tibioperoneal segment. Patients of peripheral arterial disease (PAD) having no symptoms of coronary artery disease (CAD) are more likely to have severe coronary artery involvement. Coronary angiogram should be done in patient with PAD to detect previously undetected CAD and pattern of PAD reflects the severity and involvement of coronary arteries.

AB - Since its inception, the neonatal mechanical ventilator has been considered an essential tool for managing preterm neonates with Respiratory Distress Syndrome (RDS) and is still regarded as an integral component in the neonatal respiratory care continuum. Mechanical ventilation of newborn has been practiced for several years with several advances made in the way. This clinical intervention study was done to analyze immediate outcome of preterm neonates with RDS required mechanical ventilation and conducted on preterm neonates with RDS required mechanical ventilation from July 2014 to June 2015. Total of 31 preterm neonates with RDS were mechanically ventilated during the study period, of which 77.42% (N=24) survived. The survival rate was highest among 30- <34 weeks (100%) gestational age (GA) group and lowest in 27- <30 weeks (56%) GA, (p=0.0036). The neonates with Birth Weight (BW) 1500gm -1800gm were higher rate of recovery which was 100% and gradually declined in 1000-1499gm (93.75%) and 800-999gm (33.33%) BW groups (p=0.00083). In this study most of the neonates were male (61.29%) but recovery rate was relatively better among baby girls (83.33%) than baby boys (73.68%) (p=0.53). RDS with surfactant therapy was better outcome than non surfactant group & survival of neonates who got surfactant were 93.33% & non surfactant neonates were 62.50%, (p=0.040). Majority (71.43%) of RDS with surfactant therapy recovered earlier <7 days than non surfactant therapy neonates (30.00%) and most of non surfactant neonates (70.00%) required prolonged ventilator support >7days (p=0.045). During the period of ventilation a total 17(54.84%) neonates developed different complications, of which ventilator associated pneumonia was (16.13%), sepsis (16.13%), pneumothorax (9.68%), pulmonary hemorrhage (6.45%) and intraventricular hemorrhage (6.45%) and among them 10 neonates recovered. No complications encountered in 14(45.16%) neonates, all of them survived, (p=0.0064). All (N=31) preterm neonates were candidate for surfactant therapy but only 15 neonates got surfactant therapy, remaining (N=16) did not get for their financial issue. As mechanical ventilation with surfactant therapy reduces the neonatal mortality; hence, facilities for neonatal ventilation and cost effective surfactant therapy should be included in the regional and central hospitals providing intensive care for neonates.

AB - High-energy tibial plateau fractures associated with severe soft tissue injury are difficult to manage. The risk of wound complications following open reduction and internal fixation is notably high owing to extensive soft tissue dissection. Alternatively, application of Ilizarov ring fixator minimizes soft tissue dissection and provides adequate fracture stabilization to allow early range of motion and correction of any mal-alignment. With this technique, soft tissue complications particularly surgical site infections are expected to be significantly reduced. This prospective interventional study was conducted from January 2012 to December 2013 at National Institute of Traumatology and Orthopaedic Rehabilitation (NITOR), Dhaka, Bangladesh. Ten patients with tibial plateau fracture Schatzker type VI were treated with Ilizarov ring fixator. Patients were visited routinely and final outcome evaluation done according to Rasmussen's functional grading system and radiological evaluation. Among the 10 patients of type-VI Schatzker tibial plateau fractures, the mean range of knee movement was 95.5 degrees . The mean Rasmussen functional score was 23.6 (range, 16-28): excellent in 3 patients, good in 5 and fair in 2.

AB - Tuberous sclerosis complex (TSC) is a common neurocutaneous disorder characterized by hamartomatous changes in the lungs, brain, kidneys, skin, heart, and other organs. This retrospective study was done to see the clinical presentation and neuro imaging pattern of TSC in a tertiary care centre of Bangladesh and was conducted at Pediatric Neurology Unit of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from January 2013 to December 2013. Among total 10 patients male-female ratio was 3:2. Commonest age group was 1-5 year in 50%. Common cutaneous abnormality was facial angiofibroma in 100%. Commonest neurological presentation was epilepsy in100%, ASD in 20% patient. Common renal manifestation was multicystic kidney disease (20%). CT/MRI findings were periventricular calcifications in 70% patients. In this study facial angiofibroma is the most common skin manifestation and epilepsy is the common neurological presentationandperiventricular calcification is the most common neuro-radiological findings in tuberous sclerosis complex. PMID- 29459607 TI - Forgotten, Encrusted Ureteral Stents: Removal - Multimodal Endourologic Approach. AB - Ureteral stent placement is a common procedure in urologic practice. Forgotten, encrusted D/J stents represent a difficult problem for urologists. The major complications are infection, impaired renal function, migration, encrustation, stone formation and multiple fragmentation of stent. A consensus on the best therapeutic approach is still lacking. Here we present our experience with endoscopic management of this challenging problem and discuss the multimodal endourologic approaches for treating forgotten, encrusted ureteral stents. In this prospective observational study 29 patients (17 males and 12 females), age ranges from 19 to 57 years with 35 (23 unilateral and 6 bilateral) encrusted ureteral stents, indwelling for 5 to 78 months were treated in the Department of Urology, Dhaka Medical College Hospital (DMCH), Dhaka, Bangladesh from January 2011 to December 2015. All patients were evaluated by urine culture and sensitivity, renal function. Stent encrustation and the associated stone burden were estimated by plain radiograph. Treatment decisions were made based on the clinical presentation, degree of encrustation, stone burden and image findings. Patients were followed up to 06 months. The main indications for stenting were pyelolithotomy, ureterolithotomy, ureteroneocystostomy, URS and pyeloplasty. In kidney, mild encrustation was common (48.3%) moderate encrustation (27.6%) was less common; where as in ureter and urinary bladder, moderate encrustation was common (72.4% and 44.8%). Over three-quarters 22(75.9%) of the patients underwent extracorporeal shockwave lithotripsy (ESWL) and 10(34.5%) percuteneousnephrostomy preoperatively. Retrograde ureteroscopy with intracorporeal lithotripsy (URS & ICPL) was done in 29 cases and cystolitholapaxy (CLL) in 16(55%) cases. Cystolithotomy & PCNL was rarely done. The mean number of procedures was 2.8 (range: 1-7). Using these multimodal approaches, all stents and associated stones were eventually removed with minor complications. Nine patients developed haematuria, 5 urosepsis and 4 both haematuria & urosepsis. Multimodal endourologic approaches can safely remove forgotten, encrusted D/J stents, if treatment is tailored to the volume of encrustation and associated stone. Imaging evaluation and documentation of negative urine culture are imperative prior to any attempt to remove the stent. PMID- 29459608 TI - Distribution Pattern and Outcome of the Patients in the Intensive Care Unit of Bangabandhu Sheikh Mujib Medical University: A Short Term Analysis. AB - The aim of the study was to describe the characteristics of patients admitted to intensive care unit and their outcome in Bangabandhu Sheikh Mujib Medical University, Bangladesh. This retrospective, descriptive study was conducted in the intensive care unit of Bangabandhu Sheikh Mujib Medical University (BSMMU) from January 2016 to June 2016. Data was retrieved from hospital records of all admitted patients regarding age, gender, admission source, reason for admission, length of ICU stay, requirement of mechanical ventilation, number of organ failure and their outcome. During this study period, the total number of patients admitted was 225; most of them were males (148, 65.7%). Among the 225 patients, the highest number of admission was comprised of intracranial haemorrhage (22.6%), followed by sepsis (12.4%), acute respiratory distress syndrome (10.2%), acute renal failure (9.3%) malignancy (8.8%) and ischemic stroke (8.0%). Mean age of the patient was 54+/-18 years and mean length of ICU stay was 6.8+/-3 days. Out of 225 patients, 87 expired (38.6%). Majority of the patients required mechanical ventilation (69.3%) and had multi organ failure (59.8%). Most of the expiries were due to intracranial haemorrhage (24.1%); followed by acute respiratory distress syndrome (12.6%), malignancy (12.6%) and sepsis (11.4%). Elderly age (>65 years), requirement of mechanical ventilation and multiorgan failure had significant relationship (p<0.05) with overall ICU mortality. Intracranial haemorrhage, sepsis, acute respiratory distress syndrome were the main reasons for admissions in ICU, while mortality was highest for intracranial haemorrhage. Developing a well equipped neurological ICU with adequately trained staff will help to improve the outcome of patients. PMID- 29459609 TI - Psychiatric Morbidities among Male Juvenile Offenders: A Cross Sectional Comparison in Bangladesh. AB - Inmates of Juvenile Developmental Centers are the special group of youth population who are in conflict with law and are vulnerable to psychiatric disorders. It was aimed to see the variation of prevalence and type of psychiatric disorders in institutionalized male juvenile offenders and non offenders of same age, sex and socioeconomic group in the community. The association of mental disorders was examined in 138 male inmates of Juvenile Development Centers and 138 randomly selected comparison subjects in community. One stage-structured assessment of psychopathology was carried out by using a structured and valid Bangla version of the Development and Well-Being Assessment (DAWBA). Psychiatric diagnosis was established after scoring from DAWBA that is actually corresponds to diagnosis of ICD-10 for research. It was revealed that, of those who were in conflict with law, 57.2% had mental disorder, whereas 9.4% of non-offenders had psychiatric disorder. Among the offenders with psychiatric disorders, most of them (16.7%) suffered from Conduct Disorder (CD), followed by Major Depressive Disorder (MDD). On the other hand, among the non-offenders with psychiatric disorder 2.2% suffered from CD. Study revealed that psychiatric disorders are more prevalent among the male juvenile offenders with comparison to non-offenders. Broad-based multi centered and cross cultural replication study can generalize the findings. PMID- 29459610 TI - Admission Troponin I and Post Thrombolytic ST-Segment Resolution in Prediction of Early Risk Stratification in ST- Elevation Myocardial Infarction. AB - The prognostic value of admission troponin I (tnI) levels and the resolution of the ST-segment elevation in ST-elevation myocardial infarction (STEMI) is well established. However, the combination of these two early available markers for predicting the risk of early mortality has not been evaluated yet. This prospective analytical study conducted in the department of Cardiology, Sir Salimullah Medical College and Mitford Hospital, Dhaka and NICVD, Dhaka, Bangladesh from March 2004 to February 2005. We have evaluated 80 patients with streptokinase treated STEMI who had both admission troponin I and ST-monitoring. We used a prospectively defined cut-off value of troponin I of 0.1ng/ml. For ST segment resolution, a cut-off of 50% measured after 90 minutes was used. Both a troponin I >0.1ng/ml and ST segment resolution <50% was related to higher early mortality; 16.7% vs. 14.3% (p<0.001) and 57.1% vs. 1.7% (p<0.001) respectively. In a multivariate analysis ST-segment resolution was and troponin I showed a strong trend to be independently related to early mortality. The combination of both further improved risk stratification. The early mortality in the group with elevation of troponin I and without ST-segment resolution compared to the group without troponin I elevation and with ST-segment resolution was 55.6% vs. 0%. Both troponin I on admission and ST-segment resolution after 90 minutes are strong predictors of early mortality. The combination of both gives additive early information about prognosis and further improves risk stratification. PMID- 29459611 TI - Non-convulsive Status Epilepticus in Children: Clinical Profile, EEG Characteristics and Treatment. AB - Non-convulsive status epilepticus (NCSE) is a term used to denote a range of conditions in which electrographic seizure activity is prolonged and results in non-convulsive clinical symptoms. This study was done to describe the clinical spectrum, EEG findings and to evaluate the efficacy of different therapeutic agents in children with NCSE in 33 patients from January 2011 to December 2015 period. All patients had EEG before and after treatment. Age range was 6 months to 14 year, 25 were male. Regarding development status, 48% had developmental delay, 21% had normal development, 9% had regression and 21% had both developmental delay and regression. Twenty nine cases were previously diagnosed as epilepsy. EEG diagnosis was as follows: Generalized NCSE 23(69%), focal 9(27%), unknown 1(3%). Eighteen patients were treated with Midazolam drip out of which 1 patient had complete remission in EEG, 6 had >80% remission, 5 had >50% remission and 5 patients had minimal or no response. Thirteen patients were treated with methyl prednisolone bolus out of which 2 patients had complete remission, 4 patients had >80% remission while 4 patients had >50% remission and 3 patients showed no response. NCSE may present with various clinical feature without any convulsion. Midazolam, methyl prednisolone and oral drugs are equally effective for treatment of NCSE. However, further randomized controlled study is needed to chalk out management of NCSE. PMID- 29459612 TI - Review of Uterine Sling after Five Years of Operation in a 40 Years Lady. AB - Uterine sling is a operation, done with own rectus sleeve to correct the uterine descend. If necessary correction of cystocele and/or rectocele and or perineal tear done on the same sitting. After 5 years of such operation abdomen of Mrs. X was opened due to ovarian cyst in Nirapad Hospital, Shantinagar, Dhaka, Bangladesh on August 2016. Uterus was found in normal position and size. Rectus sleeves were found attached with the uterus where it was anchored. Omentum was attached over the rectus sleeves and sealed the weak points at both lateral ends of the rectus sleeves through which the sleeves were taken to the abdominal cavity. Omentum was also attached to the posterior leaf of the broad ligaments where the sleeves were sutured to minimize the dead spaces. During this 5 years period the patient felt no discomfort or pain due to the sling or experiences any further descend of the uterus. PMID- 29459613 TI - Complete Annular Pancreas with Concurrent Entero-Pancreatico-Biliary Symptoms in Adult: A Case Report. AB - Complete Annular pancreas (AP) is a rare congenital anomaly, often presented and operated at the early age of life. Adult presentation group usually presents with either biliary or duodenal or pancreatic symptoms. We report a case of 43 years old female presenting with concurrent enteric, biliary and pancreatic symptoms admitted on April 2016 in Hepatobiliary and Pancreatic Surgery Department of BSMMU, Dhaka, Bangladesh. A complete type of annular pancreas with partial duodenal stenosis and dilated common bile duct was observed during laparotomy. We performed gastrojejunostomy as well as hepaticojejunostomy (Roux-en-Y anastomosis). Patient was discharged in a good symptom free condition. Complete Annular Pancreas can present at any age, with any one or all of the biliary, pancreatic or duodenal symptoms. Surgery is the treatment of choice and has a good outcome. PMID- 29459614 TI - A Case of Severe Coarctation of Aorta Associated With Bicuspid Aortic Valve Managed Surgically. AB - Coarctation of the aorta is a congenital cardiac malformation that can go undiagnosed until old age with only hypertension as a marker of its presence because clinical signs can be subtle and overlooked if a complete physical exam is not performed. Long-term survival is exceptional in patients with untreated aortic coarctation. In this case report, we present a late diagnosis of aortic coarctation in a 45-year-old male. Our patient was relatively asymptomatic until he presented with exertional dyspnea and fatigue in his fourth decade of life in Bangabandhu Sheikh Mujib Medical University (BSMMU), on the month of August, 2016. The patient was managed by surgery of aorta. After the 6 months follow-up visit, the patient was in good clinical condition. PMID- 29459615 TI - Double Heterozygous For Haemoglobin S and Haemoglobin E. AB - Here we present a Bangladeshi family where out of four family members two (mother and son) inherited both haemoglobin (HbS) S and haemoglobin (HbE) E gene confirming the diagnosis of double heterozygous state for HbS and HbE, presented in the Armed Forces Institute of Pathology (AFIP), Dhaka Cantonment, Dhaka, Bangladesh on the month of July 2016. Among other two members, one (daughter) inherited HbS and other (father) HbE. Double heterozygous state for HbS and HbE is a rare condition in this subcontinent especially in Bangladesh. HbS is rare but HbE is prevalent in Bangladesh. Co-inheritance of both HbS and HbE is therefore uncommon in this country in comparison to HbE/beta - thalassaemia. Though the double heterozygous state for HbS and HbE is rare and the patients are usually asymptomatic but their documentation is important for genetic counseling and to determine the reproductive risk of the family. PMID- 29459616 TI - Gliomatosis Cerebri: A Rare Brain Tumor. AB - Gliomatosis Cerebri is a rare brain tumor. There is diversity of presentation in cases due to the nature of its diffuse involvement. Very recently, on February 2016 in the department of Paediatric Neurology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh we encountered a 10 years old boy who initially mimicked as tuberculoma of brain but later on diagnosed as Gliomatosis Cerebri on the basis of brain MRI and brain biopsy. Prognosis is always very gloomy regardless of the treatment strategy adopted. The boy died within one year after confirmation of diagnosis even after getting adequate medical management and radiation therapy. PMID- 29459617 TI - NGAL (Neutrophil Gelatinase-associated Lipocalin) is an Early Predictor of Acute Kidney Injury after Cardiac Surgery and Variation of NGAL Values in Homogenous Study Subject. AB - Isolated CABG (coronary artery bypass grafting) has the lowest incidence of AKI (Acute Kidney Injury), followed by valvular surgery and then, combined CABG with valvular surgery. Due to the difference in baseline characteristics and in surgery type, the range of incidence is between 8.9 and 39% based on RIFLE (Risk Injury failure loss end stage kidney disease) or AKIN (Acute Kidney Injury Network) criteria. The advent of novel biomarkers of kidney injury has opened a new era of early detection and prognosis prediction for AKI. NGAL is a small molecule of 178 amino acids that belongs to the super family of lipocalins, which are proteins specialized in binding and transporting small hydrophobic molecules. The expression of NGAL raises 1000 fold in humans and rodents in response to renal tubular injury and it appears so rapidly in the urine and serum that it is useful as an early biomarker of renal failure. The role of plasma NGAL to classify AKI severity and predict the need for RRT (renal replacement therapy) after cardiac surgery has been suggested. Although study subjects were more or less from same cohort (All undergone cardiac surgery), previous studies showed that NGAL raised differently in different proportion. NGAL as an early AKI marker has successfully passed through the pre-clinical, assay development and initial clinical testing stages. It is badly need to enter in a consensus about the cutoff value of NGAL which should help the physician about leveling a case as AKI or non AKI and their consequence management. PMID- 29459618 TI - Irritable Bowel Syndrome: Is it Rare in Children? AB - Irritable bowel syndrome (IBS) is one of the most common and best studied disorders among the group of functional gastrointestinal disorders. It is a functional bowel disorder in which abdominal pain or discomfort is associated with defecation or a change in bowel habit. Visceral hypersensitivity and increased GIT motility are the main patho-physiological mechanism for developing IBS. IBS present with diarrhea and constipation or both. Investigation is least needed for diagnosis of IBS rather done to exclude differential diagnosis. Diagnosis is done on the basis of Rome-III criteria. Proper counseling, dietary management, anti-spasmotic and antidepressant are the mainstay of treatment. PMID- 29459619 TI - Quality and learning aspects of the first 9000 spirometries of the LifeGene study. AB - Spirometry requires the patient to cooperate and do the manoeuvre 'right' for reliable results. Algorithms to assess test quality as well as educational recommendations for personnel are defined in guidelines. We compared the quality of forced spirometry tests performed by spirometry technicians with little or no previous experience of spirometry using spirometry systems with different modes of feedback. In both cases, the spirometry technician received general feedback on the screen based on ATS/ERS guidelines, such as 'exhale faster' and 'exhale longer'. The major difference was whether quality grading system of the complete session was available simultaneously on screen, or in the printed report afterwards. Two parts of the same population-based study (LifeGene), the pilot (LG1) and the first part (LG2) of the subsequent study, were compared retrospectively. In LG1 (on-screen grading) approved examination quality was achieved for 88% of the 10 first subjects for each spirometry technician compared to 70% in LG2 (printed grading afterwards). The corresponding values after 40 subjects was 94 % in LG1, compared to 73% in LG2, and after the first ten subjects there was no apparent quality improvement in either LG1 or LG2. The quality for LG1 is among the highest reported in the literature even though the spirometry technician were relatively inexperienced. We conclude that on-screen grading in addition to general technical quality feedback is powerful in enhancing the spirometry test session quality. PMID- 29459620 TI - New insights into the cellular responses to iron nanoparticles in Capsicum annuum. AB - In this study, the anatomical and ultrastructural responses of Capsicum annuum to iron nanoparticles (Fe NPs) were determined. The results showed that the bio effects of Fe NPs on plants could be positive or negative, depending on the additive concentrations. Low concentrations of Fe NPs were found to promote plant growth. Light and electron microscope analyses showed that the Fe NPs promoted plant growth by altering the leaf organization, and increasing the chloroplast number and grana stacking, as well as regulating the development of vascular bundles. Meanwhile, it was found that the Fe NPs could be absorbed in the roots, and then transported to the central cylinder in bio-available forms, where they were translocated and utilized by the leaves and stems. In contrast, high concentrations of Fe NPs appeared to be harmful to the plants, and the majority of Fe NPs were aggregated into cell walls and transported via the apoplastic pathway in the roots, which may potentially block the transfer of iron nutrients. Taken together, the aforementioned data showed that the rational use of Fe NPs could alleviate iron deficiency, and Fe NPs could be an ideal supply for Fe2+ ions fertilizers in agriculture. PMID- 29459621 TI - Ultrafast quantum control of ionization dynamics in krypton. AB - Ultrafast spectroscopy with attosecond resolution has enabled the real time observation of ultrafast electron dynamics in atoms, molecules and solids. These experiments employ attosecond pulses or pulse trains and explore dynamical processes in a pump-probe scheme that is selectively sensitive to electronic state of matter via photoelectron or XUV absorption spectroscopy or that includes changes of the ionic state detected via photo-ion mass spectrometry. Here, we demonstrate how the implementation of combined photo-ion and absorption spectroscopy with attosecond resolution enables tracking the complex multidimensional excitation and decay cascade of an Auger auto-ionization process of a few femtoseconds in highly excited krypton. In tandem with theory, our study reveals the role of intermediate electronic states in the formation of multiply charged ions. Amplitude tuning of a dressing laser field addresses different groups of decay channels and allows exerting temporal and quantitative control over the ionization dynamics in rare gas atoms. PMID- 29459622 TI - Effects of predispersal insect seed predation on the early life history stages of a rare cold sand-desert legume. AB - Seed predation by insects is common in seeds of Fabaceae (legume) species with physical dormancy (PY). However, the consequences of insect seed predation on the life history of legumes with PY have been little studied. In the largest genus of seed plants, Astragalus (Fabaceae), only one study has tested the effects of insect predation on germination, and none has tested it directly on seedling survival. Thus, we tested the effects of insect predation on seed germination and seedling growth and survival of Astragalus lehmannianus, a central Asian sand desert endemic. Under laboratory conditions, seeds lightly predated in the natural habitat of this perennial legume germinated to a much higher percentage than intact seeds, and seedlings from predated and nonpredated seeds survived and grew about equally well. Further, in contrast to our prediction seedlings from predated seeds that germinated "out-of-season" under near-natural conditions in NW China survived over winter. The implication of our results is that individual plants from predated seeds that germinate early (in our case autumn) potentially have a fitness advantage over those from nonpredated seeds, which delay germination until spring of a subsequent year. PMID- 29459623 TI - Rapid emergence of independent "chromosomal lineages" in silvered-leaf monkey triggered by Y/autosome translocation. AB - Sex/autosome translocations are rare events. The only known example in catarrhines is in the silvered-leaf monkey. Here the Y chromosome was reciprocally translocated with chromosome 1. The rearrangement produced an X1X2Y1Y2 sex chromosome system. At least three chromosomal variants of the intact chromosome 1 are known to exist. We characterized in high resolution the translocation products (Y1 and Y2) and the polymorphic forms of the intact chromosome 1 with a panel of more than 150 human BAC clones. We showed that the translocation products were extremely rearranged, in contrast to the high level of marker order conservation of the other silvered-leaf monkey chromosomes. Surprisingly, each translocation product appeared to form independent "chromosome lineages"; each having a myriad of distinct rearrangements. We reconstructed the evolutionary history of the translocation products by comparing the homologous chromosomes of two other colobine species: the African mantled guereza and the Indian langur. The results showed a massive reuse of breakpoints: only 12, out of the 40 breaks occurred in domains never reused in other rearrangements, while, strikingly, some domains were used up to four times. Such frequent breakpoint reuse if proved to be a general phenomenon has profound implications for mechanisms of chromosome evolution. PMID- 29459624 TI - Background matching in the brown shrimp Crangon crangon: adaptive camouflage and behavioural-plasticity. AB - A combination of burrowing behaviour and very efficient background matching makes the brown shrimp Crangon crangon almost invisible to potential predators and prey. This raises questions on how shrimp succeed in concealing themselves in the heterogeneous and dynamic estuarine habitats they inhabit and what type of environmental variables and behavioural factors affect their colour change abilities. Using a series of behavioural experiments, we show that the brown shrimp is capable of repeated fast colour adaptations (20% change in dark pigment cover within one hour) and that its background matching ability is mainly influenced by illumination and sediment colour. Novel insights are provided on the occurrence of non-adaptive (possibly stress) responses to background changes after long-time exposure to a constant background colour or during unfavourable conditions for burying. Shrimp showed high levels of intra- and inter-individual variation, demonstrating a complex balance between behavioural-plasticity and environmental adaptation. As such, the study of crustacean colour changes represents a valuable opportunity to investigate colour adaptations in dynamic habitats and can help us to identify the mayor environmental and behavioural factors influencing the evolution of animal background matching. PMID- 29459625 TI - Molecular subtypes of Alzheimer's disease. AB - Protein misfolding and aggregation is a central feature of several neurodegenerative disorders including Alzheimer's disease (AD), in which assemblies of amyloid beta (Abeta) peptides accumulate in the brain in the form of parenchymal and/or vascular amyloid. A widely accepted concept is that AD is characterized by distinct clinical and neuropathological phenotypes. Recent studies revealed that Abeta assemblies might have structural differences among AD brains and that such pleomorphic assemblies can correlate with distinct disease phenotypes. We found that in both sporadic and inherited forms of AD, amyloid aggregates differ in the biochemical composition of Abeta species. These differences affect the physicochemical properties of Abeta assemblies including aggregation kinetics, resistance to degradation by proteases and seeding ability. Abeta-amyloidosis can be induced and propagated in animal models by inoculation of brain extracts containing aggregated Abeta. We found that brain homogenates from AD patients with different molecular profiles of Abeta are able to induce distinct patterns of Abeta-amyloidosis when injected into mice. Overall these data suggest that the assembly of mixtures of Abeta peptides into different Abeta seeds leads to the formation of distinct subtypes of amyloid having distinctive physicochemical and biological properties which result in the generation of distinct AD molecular subgroups. PMID- 29459626 TI - Comparative transcriptomics with self-organizing map reveals cryptic photosynthetic differences between two accessions of North American Lake cress. AB - Because natural variation in wild species is likely the result of local adaptation, it provides a valuable resource for understanding plant-environmental interactions. Rorippa aquatica (Brassicaceae) is a semi-aquatic North American plant with morphological differences between several accessions, but little information available on any physiological differences. Here, we surveyed the transcriptomes of two R. aquatica accessions and identified cryptic physiological differences between them. We first reconstructed a Rorippa phylogeny to confirm relationships between the accessions. We performed large-scale RNA-seq and de novo assembly; the resulting 87,754 unigenes were then annotated via comparisons to different databases. Between-accession physiological variation was identified with transcriptomes from both accessions. Transcriptome data were analyzed with principal component analysis and self-organizing map. Results of analyses suggested that photosynthetic capability differs between the accessions. Indeed, physiological experiments revealed between-accession variation in electron transport rate and the redox state of the plastoquinone pool. These results indicated that one accession may have adapted to differences in temperature or length of the growing season. PMID- 29459628 TI - Submarine slope failures due to pipe structure formation. AB - There is a strong spatial correlation between submarine slope failures and the occurrence of gas hydrates. This has been attributed to the dynamic nature of gas hydrate systems and the potential reduction of slope stability due to bottom water warming or sea level drop. However, 30 years of research into this process found no solid supporting evidence. Here we present new reflection seismic data from the Arctic Ocean and numerical modelling results supporting a different link between hydrates and slope stability. Hydrates reduce sediment permeability and cause build-up of overpressure at the base of the gas hydrate stability zone. Resulting hydro-fracturing forms pipe structures as pathways for overpressured fluids to migrate upward. Where these pipe structures reach shallow permeable beds, this overpressure transfers laterally and destabilises the slope. This process reconciles the spatial correlation of submarine landslides and gas hydrate, and it is independent of environmental change and water depth.

AB - Genistein, a phyto-estrogen, can potentially replace endogenous estrogens in postmenopausal women, but the underlying molecular mechanisms remain incompletely understood. To obtain insight into the effect of genistein on bone differentiation, RNA sequencing (RNA-seq) analysis was used to detect differentially expressed genes (DEGs) in genistein-treated vs. untreated MC3T3-E1 mouse osteoblastic cells. Osteoblastic cell differentiation was monitored by measuring osteoblast differentiation factors (ALP production, bone mineralization, and expression of osteoblast differentiation markers). From RNA seq analysis, a total of 132 DEGs (including 52 up-regulated and 80 down regulated genes) were identified in genistein-treated cells (FDR q-value < 0.05 and fold change > 1.5). KEGG pathway and Gene Ontology (GO) enrichment analyses were performed to estimate the biological functions of DEGs and demonstrated that these DEGs were highly enriched in functions related to chemotactic cytokines. The functional relevance of DEGs to genistein-induced osteoblastic cell differentiation was further evaluated by siRNA-mediated knockdown in MC3T3-E1 cells. These siRNA knockdown experiments (of the DEGs validated by real-time qPCR) demonstrated that two up-regulated genes (Ereg and Efcab2) enhance osteoblastic cell differentiation, while three down-regulated genes (Hrc, Gli, and Ifitm5) suppress the differentiation. These results imply their major functional roles in bone differentiation regulated by genistein. PMID- 29459629 TI - Experimental study of the anti-tumour activity and pharmacokinetics of arctigenin and its valine ester derivative. AB - Arctigenin (ARG) is a functional active component that has important physiological and pharmacological activities. The anti-tumour and anti inflammatory activities of ARG show good potential for application and development, but this material has the defect of low water solubility. In this experiment, the valine derivative of ARG (ARG-V) was designed and synthesized to overcome this disadvantage. The ARG amino acid, EDCI and DMAP were raw materials in the addition reaction, with a molar ratio of 1:2:2:0.5. The yield of ARG-V was up to 80%. ARG-V has strong anti-tumour activity in vivo and in vitro. The inhibitory rate of ARG-V was 69.2%, with less damage to the immune organs and different degrees of increased serum cytotoxicity. Moreover, the pharmacokinetics of ARG following oral administration and ARG-V following oral administration in rats were also studied. The Cmax and AUC values of ARG-V showed significant differences compared to ARG. The relative bioavailabilities of three doses of ARG V compared to ARG were 664.7%, 741.5% and 812.9%. These pharmacokinetic results may be useful for further studies of the bioactive mechanism of ARG and provide a theoretical basic for clinical use. PMID- 29459630 TI - Development of ultra-deep targeted RNA sequencing for analyzing X-chromosome inactivation in female Dent disease. AB - The pattern of X-chromosome inactivation (XCI) can affect the clinical severity of X-linked disorders in females. XCI pattern analysis has been conducted mainly by HUMARA assay, a polymerase chain reaction-based assay using a methylation sensitive restriction enzyme. However, this assay examines the XCI ratio of the androgen receptor gene at the genomic DNA level and does not reflect the ratio of either targeted gene directly or at the mRNA level. Here, we report four females with Dent disease, and we clarified the correlation between XCI and female cases of Dent disease using not only HUMARA assay but also a novel analytical method by RNA sequencing. We constructed genetic analysis for 4 female cases showing high level of urinary low-molecular-weight proteinuria and their parents. Their XCI pattern was analyzed by both HUMARA assay and an ultra-deep targeted RNA sequencing of the CLCN5 gene using genomic DNA and mRNA extracted from both leukocytes and urine sediment. All four cases possessed pathogenic variants of the CLCN5 gene. XCI analysis revealed skewed XCI in only two cases, while the other two showed random XCI. All assay results of HUMARA and targeted RNA sequencing in both leukocytes and urinary sediment were clearly identical in all four cases. We developed a novel XCI analytical assay of ultra-deep targeted RNA sequencing and revealed that skewed XCI explains the mechanism of onset of female Dent disease in only half of such cases.

AB - Kleefstra syndrome (KS) (9q34 deletion syndrome) is a rare autosomal dominant disorder characterized by intellectual disability, frequently coupled with a spectrum of complex physical and clinical manifestations. As the euchromatic histone methyltransferase-1 gene (EHMT1, GLP, or KMT1D) within the 9q34 region is deleted or mutated in most of the individuals with KS, its absence or defect in one allele is speculated to cause the major symptoms of the syndrome. Most of the EHMT1 mutations are frameshift or nonsense mutations, but two individuals with KS were reported to possess EHMT1 missense mutations. These two mutations have been predicted to cause a defective enzymatic function, but precise biochemical validation was not conducted. Therefore, we validated these two mutations by performing in vitro histone methyltransferase (HMT) activity assay and found that C1073Y and R1197W mutations severely affected the HMT activity. Additionally, the same amino-acid substitutions in mouse GLP induced impairment of in vivo GLP function. Furthermore, these two EHMT1 mutants showed defective heterocomplex formation with G9a (partner HMT) which is essential for their in vivo HMT function. Conclusively, our biochemical characterization clearly demonstrates that the previously reported two missense mutations of EHMT1 deteriorate HMT activity and GLP function, which presumably cause KS.

PMID- 29459633 TI - Self-calibrating d-scan: measuring ultrashort laser pulses on-target using an arbitrary pulse compressor. AB - In most applications of ultrashort pulse lasers, temporal compressors are used to achieve a desired pulse duration in a target or sample, and precise temporal characterization is important. The dispersion-scan (d-scan) pulse characterization technique usually involves using glass wedges to impart variable, well-defined amounts of dispersion to the pulses, while measuring the spectrum of a nonlinear signal produced by those pulses. This works very well for broadband few-cycle pulses, but longer, narrower bandwidth pulses are much more difficult to measure this way. Here we demonstrate the concept of self calibrating d-scan, which extends the applicability of the d-scan technique to pulses of arbitrary duration, enabling their complete measurement without prior knowledge of the introduced dispersion. In particular, we show that the pulse compressors already employed in chirped pulse amplification (CPA) systems can be used to simultaneously compress and measure the temporal profile of the output pulses on-target in a simple way, without the need of additional diagnostics or calibrations, while at the same time calibrating the often-unknown differential dispersion of the compressor itself. We demonstrate the technique through simulations and experiments under known conditions. Finally, we apply it to the measurement and compression of 27.5 fs pulses from a CPA laser. PMID- 29459634 TI - Multiple Kernel Learning Model for Relating Structural and Functional Connectivity in the Brain. AB - A challenging problem in cognitive neuroscience is to relate the structural connectivity (SC) to the functional connectivity (FC) to better understand how large-scale network dynamics underlying human cognition emerges from the relatively fixed SC architecture. Recent modeling attempts point to the possibility of a single diffusion kernel giving a good estimate of the FC. We highlight the shortcomings of the single-diffusion-kernel model (SDK) and propose a multi-scale diffusion scheme. Our multi-scale model is formulated as a reaction diffusion system giving rise to spatio-temporal patterns on a fixed topology. We hypothesize the presence of inter-regional co-activations (latent parameters) that combine diffusion kernels at multiple scales to characterize how FC could arise from SC. We formulated a multiple kernel learning (MKL) scheme to estimate the latent parameters from training data. Our model is analytically tractable and complex enough to capture the details of the underlying biological phenomena. The parameters learned by the MKL model lead to highly accurate predictions of subject-specific FCs from test datasets at a rate of 71%, surpassing the performance of the existing linear and non-linear models. We provide an example of how these latent parameters could be used to characterize age-specific reorganization in the brain structure and function. PMID- 29459635 TI - Multiresolution Consensus Clustering in Networks. AB - Networks often exhibit structure at disparate scales. We propose a method for identifying community structure at different scales based on multiresolution modularity and consensus clustering. Our contribution consists of two parts. First, we propose a strategy for sampling the entire range of possible resolutions for the multiresolution modularity quality function. Our approach is directly based on the properties of modularity and, in particular, provides a natural way of avoiding the need to increase the resolution parameter by several orders of magnitude to break a few remaining small communities, necessitating the introduction of ad-hoc limits to the resolution range with standard sampling approaches. Second, we propose a hierarchical consensus clustering procedure, based on a modified modularity, that allows one to construct a hierarchical consensus structure given a set of input partitions. While here we are interested in its application to partitions sampled using multiresolution modularity, this consensus clustering procedure can be applied to the output of any clustering algorithm. As such, we see many potential applications of the individual parts of our multiresolution consensus clustering procedure in addition to using the procedure itself to identify hierarchical structure in networks. PMID- 29459636 TI - On mechanical behaviors of few-layer black phosphorus. AB - This paper investigates the mechanical behaviors of few-layer black phosphorus (FLBP) by using molecular dynamics simulations. Results show that both tensile and compressive behaviors are strongly anisotropic in the armchair and zigzag directions due to the unidirectional puckers in each atomic layer, and that the compressive behavior is dependent on the number of atomic layers. In particular, the compressive and buckling strengths of FLBP can be significantly enhanced by stacking more atomic layers together, while this has little influence on both Young's modulus and tensile strength. It is interesting to found that increasing the number of atomic layers in FLBP or the dimension ratio can lead to a drastically reduced flexibility in armchair direction, showing that both compressive and buckling strengths become higher than those in zigzag direction. It is also demonstrated that the reorientation of FLBP's atomic configuration occurs under certain conditions. The mechanism of deformation underlying the mechanical behaviors of FLBP is also discussed, suggesting that changing the number of atomic layers is an effective way to engineer two-dimensional materials for desired material properties.

AB - Identification of inflammatory mediators that regulate the vascular response to vasopressor molecules may aid in the development of novel therapeutic agents to treat or prevent hypertensive vascular diseases. Leukocytes have recently been shown to be capable of modifying blood pressure responses to vasopressor molecules. The purpose of this study was to test the hypothesis that deficiency of the leukocyte ligand, Psgl-1, would reduce the pressor response to angiotensin II (Ang II). Mice deficient in Psgl-1 (Psgl-1-/-) along with wild-type (WT) controls were treated for 2 weeks with a continuous infusion of Ang II. No differences in blood pressure between the groups were noted at baseline, however after 5 days of Ang II infusion, systolic blood pressures were higher in WT compared to Psgl-1-/- mice. The pressor response to acute administration of high dose Ang II was also attenuated in Psgl-1-/- compared to WT mice. Chimeric mice with hematopoietic deficiency of Psgl-1 similarly showed a reduced pressor response to Ang II. This effect was associated with reduced plasma interleukin-17 (IL-17) levels in Psgl-1-/- mice and the reduced pressor response was restored by administration of recombinant IL-17. In conclusion, hematopoietic deficiency of Psgl-1 attenuates Ang II-induced hypertension, an effect that may be mediated by reduced IL-17.

AB - Metallic nanostructures have become popular for applications in therapeutics, catalysts, imaging, and gene delivery. Molecular dynamics simulations are gaining influence to predict nanostructure assembly and performance; however, instantaneous polarization effects due to induced charges in the free electron gas are not routinely included. Here we present a simple, compatible, and accurate polarizable potential for gold that consists of a Lennard-Jones potential and a harmonically coupled core-shell charge pair for every metal atom. The model reproduces the classical image potential of adsorbed ions as well as surface, bulk, and aqueous interfacial properties in excellent agreement with experiment. Induced charges affect the adsorption of ions onto gold surfaces in the gas phase at a strength similar to chemical bonds while ions and charged peptides in solution are influenced at a strength similar to intermolecular bonds. The proposed model can be applied to complex gold interfaces, electrode processes, and extended to other metals. PMID- 29459639 TI - Imaging genotyping of functional signaling pathways in lung squamous cell carcinoma using a radiomics approach. AB - Imaging features can be useful for identifying distinct genomic differences and have predictive power for certain phenotypes attributed to genomic mutations. We aimed to identify predictive imaging biomarkers that underpin genomic alterations and clinical outcomes in lung squamous cell carcinoma (SQCC) using a radiomics approach. In 57 patients with lung SQCC who underwent preoperative computed tomography (CT) and whole-exome DNA sequencing, 63 quantitative imaging features were extracted from CT and 73 clinicoradiological features including imaging features were classified into 8 categories: clinical, global, histogram-based, lung cancer-specific, shape, local, regional, and emphysema. Mutational profiles for core signaling pathways of lung SQCC were classified into five categories: redox stress, apoptosis, proliferation, differentiation, and chromatin remodelers. Range and right lung volume was significantly associated with alternation of apoptosis and proliferation pathway (p = 0.03, and p = 0.03). Energy was associated with the redox stress pathway (p = 0.06). None of the clinicoradiological features showed any significant association with the alteration of differentiation and chromatin remodelers pathway. This study showed that radiomic features indicating five different functional pathways of lung SQCC were different form one another. Radiomics approaches to lung SQCC have the potential to noninvasively predict alterations in core signaling pathways and clinical outcome. PMID- 29459640 TI - Self-assembled Collagen-Fibrin Hydrogel Reinforces Tissue Engineered Adventitia Vessels Seeded with Human Fibroblasts. AB - Efforts for tissue engineering vascular grafts focuses on the tunica media and intima, although the tunica adventitia serves as the primary structural support for blood vessels. In surgery, during endarterectomies, surgeons can strip the vessel, leaving the adventitia as the main strength layer to close the vessel. Here, we adapted our recently developed technique of forming vascular tissue rings then stacking the rings into a tubular structure, to accommodate human fibroblasts to create adventitia vessels in 8 days. Collagen production and fibril cross-linking was augmented with TGF-beta and ascorbic acid, significantly increasing tensile strength to 57.8 +/- 3.07 kPa (p = 0.008). Collagen type I gel was added to the base fibrin hydrogel to further increase strength. Groups were: Fibrin only; 0.7 mg/ml COL; 1.7 mg/ml COL; and 2.2 mg/ml COL. The 0.7 mg/ml collagen rings resulted in the highest tensile strength at 77.0 +/- 18.1 kPa (p = 0.015). Culture periods of 1-2 weeks resulted in an increase in extracellular matrix deposition and significantly higher failure strength but not ultimate tensile strength. Histological analysis showed the 0.7 mg/ml COL group had significantly more, mature collagen. Thus, a hydrogel of 0.7 mg/ml collagen in fibrin was ideal for creating and strengthening engineered adventitia vessels. PMID- 29459642 TI - Decontamination of Petroleum-Contaminated Soils Using The Electrochemical Technique: Remediation Degree and Energy Consumption. AB - Currently, there are different remediation technologies for contaminated soils, but the selection of the best technology must be not only the treatment efficiency but also the energy consumption (costs) during its application. This paper is focused on assessing energy consumption related to the electrochemical treatment of polluted soil with petroleum hydrocarbons. In the framework of a research project, two types of experiments were conducted using soil that was artificially contaminated with diesel fuel at the same level of contamination. The experimental conditions considered for each experiment were: different amounts of contaminated soils (6 kg and 18 kg, respectively), the same current intensity level (0.25A and 0.5A), three different contamination degrees (1%, 2.5% and 5%) and the same time for application of the electrochemical treatment. The remediation degree concerning the removal of petroleum hydrocarbons from soil increased over time by approximately 20% over 7 days. With regard to energy consumption, the results revealed that with an increase in the quantity of treated soil of approximately three times, the specific energy consumption decreased from 2.94 kWh/kg treated soil to 1.64 kWh/kg treated soil.

AB - The aim of this study was to clarify the mechanism of disuse-induced muscle hyperalgesia through the evaluation of the pharmacological behaviour of muscle hyperalgesia profiles in chronic post-cast pain (CPCP) rats with acute and chronic-phase mirror-image muscle hyperalgesia treated with diclofenac (NSAID), pregabalin (an inhibitor of Ca2+ channel alpha2delta), and duloxetine (SNRI). After 2 weeks of cast immobilization, the peak cross-sectional area and muscle wet weight of the ipsilateral soleus and gastrocnemius muscles decreased more significantly in CPCP rats than in untreated rats. Histological findings revealed disuse-induced muscle atrophy in CPCP rats. The blood biochemical parameters of CPCP rats in acute and chronic phases did not differ significantly from those of untreated rats. The diclofenac and pregabalin-treated groups exhibited no improvement in acute or chronic muscle hyperalgesia. In contrast, the duloxetine treated group exhibited an improvement in acute muscle hyperalgesia, but showed no apparent effect on chronic muscle hyperalgesia on ipsilateral or contralateral sides. However, the chronic muscle hyperalgesia was reversed by intrathecal administration of DAMGO (a MU-opioid receptor agonist). The results suggest that chronic muscle hyperalgesia in CPCP rats did not result from an inflammatory mechanism, and there is only a low probability that it's caused by a neuropathic mechanism. PMID- 29459645 TI - Inhibition of ATG12-mediated autophagy by miR-214 enhances radiosensitivity in colorectal cancer. AB - Radioresistance hampers success in the treatment of patients with advanced colorectal cancer (CRC). Improving our understanding of the underlying mechanisms of radioresistance could increase patients' response to irradiation (IR). MicroRNAs are a class of small RNAs involved in tumor therapy response to radiation. Here we found that miR-214 was markedly decreased in CRC cell lines and blood of CRC patients after IR exposure. Meanwhile, autophagy was enhanced in irradiated CRC cells. Mechanically, ATG12 was predicted and identified as a direct target of miR-214 by dual luciferase assay, qPCR, and Western blot. In vitro and in vivo experiments showed that miR-214 promoted radiosensitivity by inhibiting IR-induced autophagy. Restoration of ATG12 attenuated miR-214-mediated inhibition of cell growth and survival in response to IR. Importantly, miR-214 was highly expressed in radiosensitive CRC specimens and negatively correlated with plasma level of CEA. Moreover, ATG12 and LC3 expressions were increased in radioresistant CRC specimens. Our study elucidates that miR-214 promotes radiosensitivity by inhibition of ATG12-mediated autophagy in CRC. Importantly, miR-214 is a determinant of CRC irradiation response and may serve as a potential therapeutic target in CRC treatment.

AB - In this study, Poly(butylene succinate)/bamboo powder (PBS/BP) was newly applied and tested for 8 months as the carbon source in two moving bed reactors for nitrate removal in real RAS wastewater (fresh/sea water), with the purposes of simultaneous reducing the cost of PBS packing and effluent DOC. Fast start-ups were obtained in both reactors, in which high denitrification rates were observed (0.68 +/- 0.03 and 0.83 +/- 0.11 kg [Formula: see text]-N m-3 d-1 for fresh and sea water, respectively) with no nitrite and low ammonia accumulation. Reduced DOC concentrations in the effluents were also observed compared to pure PBS. The freezing of PBS/BP showed a further slower release of DOC, which might be beneficial to the life of the PBS/BP for the denitrification process, however, microbial activity, especially in high salinity wastewater, was observed to have declined. Illumina sequencing revealed that the autotrophic genus arcobacter was discovered first time in solid-phase denitrification system with salinity. Redundancy analysis (RDA) was used to reveal the relationships between environmental factors and the microbial community. In overall, PBS/BP blends were proven to be an economically attractive carbon source for nitrate removal in RAS.

AB - Diglyphus species are dominant biocontrol agents for suppressing outbreaks of agromyzid leafminers in fields. In July 2015, we collected a new thelytokous species of Diglyphus in Qinghai, China. The wasp is here named as D. wani Liu, Zhu & Yefremova sp. nov., based on morphological and molecular analyses. The life history and biocontrol potential of the wasp were studied in the laboratory and by providing Liriomyza sativae larvae. The intrinsic rate of increase, finite rate of increase, and mean generation time were 0.2373 d-1, 1.2678 d-1, and 15.9 d, respectively. The wasps showed three types of host-killing behaviour, namely parasitism, host feeding and host stinging, resulting in 47.6, 94.4 and 3.4 host larvae killed per wasp over a lifetime, respectively. The finite total host killing rate was 1.0071 and the wasp showed strong synovigeny. The wasp may be a crucial biocontrol agent against agromyzid leafminers.

AB - Anthropogenic activity is now recognised as having profoundly and permanently altered the Earth system, suggesting we have entered a human-dominated geological epoch, the 'Anthropocene'. To formally define the onset of the Anthropocene, a synchronous global signature within geological-forming materials is required. Here we report a series of precisely-dated tree-ring records from Campbell Island (Southern Ocean) that capture peak atmospheric radiocarbon (14C) resulting from Northern Hemisphere-dominated thermonuclear bomb tests during the 1950s and 1960s. The only alien tree on the island, a Sitka spruce (Picea sitchensis), allows us to seasonally-resolve Southern Hemisphere atmospheric 14C, demonstrating the 'bomb peak' in this remote and pristine location occurred in the last-quarter of 1965 (October-December), coincident with the broader changes associated with the post-World War II 'Great Acceleration' in industrial capacity and consumption. Our findings provide a precisely-resolved potential Global Stratotype Section and Point (GSSP) or 'golden spike', marking the onset of the Anthropocene Epoch. PMID- 29459649 TI - Evolving Bacterial Fitness with an Expanded Genetic Code. AB - Since the fixation of the genetic code, evolution has largely been confined to 20 proteinogenic amino acids. The development of orthogonal translation systems that allow for the codon-specific incorporation of noncanonical amino acids may provide a means to expand the code, but these translation systems cannot be simply superimposed on cells that have spent billions of years optimizing their genomes with the canonical code. We have therefore carried out directed evolution experiments with an orthogonal translation system that inserts 3-nitro-L-tyrosine across from amber codons, creating a 21 amino acid genetic code in which the amber stop codon ambiguously encodes either 3-nitro-L-tyrosine or stop. The 21 amino acid code is enforced through the inclusion of an addicted, essential gene, a beta-lactamase dependent upon 3-nitro-L-tyrosine incorporation. After 2000 generations of directed evolution, the fitness deficit of the original strain was largely repaired through mutations that limited the toxicity of the noncanonical. While the evolved lineages had not resolved the ambiguous coding of the amber codon, the improvements in fitness allowed new amber codons to populate protein coding sequences.

AB - Mobile phone microscopes are a natural platform for point-of-care imaging, but current solutions require an externally powered illumination source, thereby adding bulk and cost. We present a mobile phone microscope that uses the internal flash or sunlight as the illumination source, thereby reducing complexity whilst maintaining functionality and performance. The microscope is capable of both brightfield and darkfield imaging modes, enabling microscopic visualisation of samples ranging from plant to mammalian cells. We describe the microscope design principles, assembly process, and demonstrate its imaging capabilities through the visualisation of unlabelled cell nuclei to observing the motility of cattle sperm and zooplankton. PMID- 29459651 TI - Crystal structure of the hydroxylaminopurine resistance protein, YiiM, and its putative molybdenum cofactor-binding catalytic site. AB - The molybdenum cofactor (Moco) is a molybdenum-conjugated prosthetic group that is ubiquitously found in plants, animals, and bacteria. Moco is required for the nitrogen-reducing reaction of the Moco sulfurase C-terminal domain (MOSC) family. Despite the biological significance of MOSC proteins in the conversion of prodrugs and resistance against mutagens, their structural features and Moco mediated catalysis mechanism have not been described in detail. YiiM is a MOSC protein that is involved in reducing mutagenic 6-N-hydroxylaminopurine to nontoxic adenine in bacteria. Here, we report two crystal structures of YiiM: one from Gram-positive Geobacillus stearothermophilus (gsYiiM) and the other from Gram-negative Escherichia coli (ecYiiM). Although gsYiiM and ecYiiM differ in oligomerization state and protein stability, both consist of three structural modules (a beta-barrel and two alpha-helix bundles) and feature a cavity surrounded by the three modules. The cavity is characterized by positive electrostatic potentials and high sequence conservation. Moreover, the ecYiiM cavity houses a phosphate group, which emulates a part of Moco, and contains a highly reactive invariant cysteine residue. We thus propose that the cavity is the catalytic site where Moco binds and the substrate is reduced. Moreover, our comparative structural analysis highlights the common but distinct structural features of MOSC proteins. PMID- 29459652 TI - Light touch.

AB - Reduced dimensionality and interlayer coupling in van der Waals materials gives rise to fundamentally different electronic 1 , optical 2 and many-body quantum3-5 properties in monolayers compared with the bulk. This layer-dependence permits the discovery of novel material properties in the monolayer regime. Ferromagnetic order in two-dimensional materials is a coveted property that would allow fundamental studies of spin behaviour in low dimensions and enable new spintronics applications6-8. Recent studies have shown that for the bulk ferromagnetic layered materials CrI3 (ref. 9 ) and Cr2Ge2Te6 (ref. 10 ), ferromagnetic order is maintained down to the ultrathin limit at low temperatures. Contrary to these observations, we report the emergence of strong ferromagnetic ordering for monolayer VSe2, a material that is paramagnetic in the bulk11,12. Importantly, the ferromagnetic ordering with a large magnetic moment persists to above room temperature, making VSe2 an attractive material for van der Waals spintronics applications. PMID- 29459654 TI - Photoelectrochemical modulation of neuronal activity with free-standing coaxial silicon nanowires. AB - Optical methods for modulating cellular behaviour are promising for both fundamental and clinical applications. However, most available methods are either mechanically invasive, require genetic manipulation of target cells or cannot provide subcellular specificity. Here, we address all these issues by showing optical neuromodulation with free-standing coaxial p-type/intrinsic/n-type silicon nanowires. We reveal the presence of atomic gold on the nanowire surfaces, likely due to gold diffusion during the material growth. To evaluate how surface gold impacts the photoelectrochemical properties of single nanowires, we used modified quartz pipettes from a patch clamp and recorded sustained cathodic photocurrents from single nanowires. We show that these currents can elicit action potentials in primary rat dorsal root ganglion neurons through a primarily atomic gold-enhanced photoelectrochemical process.

AB - Type I interferon (IFN) pathways are significant in SLE pathogenesis. Less is known about the utility of measuring markers of IFN activity in patients, or whether patient subsets with different profiles exist. We explored the longitudinal associations of IFN-induced chemokines with disease activity in a cohort of SLE patients. We calculated a validated composite score (IFN-CK) of three type I IFN-inducible chemokines (CCL2/CXCL10/CCL19) measured in 109 SLE patients (median 7 occasions over 3.2 years). Longitudinal associations of IFN-CK score with disease activity (SLEDAI-2K) and other variables were assessed using general estimating equation (GEE) methods. IFN-CK was detectable in all patients. SLEDAI-2K was significantly associated with IFN-CK, damage score and prednisolone dose. SLEDAI-2K remained significantly associated with IFN-CK over time after adjustment of covariates. Patients with high time-adjusted mean IFN-CK had lower complement and higher time-adjusted disease activity. Concordance between IFN-CK and SLEDAI-2K varied widely among patients, with some individuals having none, others weak, and a subset very high concordance. In summary in our cohort of SLE patients, serum IFN-CK varied over time with disease activity, but with wide variation in concordance. Differing relationships between IFN pathway activation and disease activity may be valuable in assigning patients to emerging IFN pathway targeting treatments. PMID- 29459656 TI - Electromyographic patterns of the rat hindlimb in response to muscle stretch after spinal cord injury. AB - STUDY DESIGN: Experimental Study. OBJECTIVES: To characterize the specific hindlimb electromyographic (EMG) patterns in response to muscle stretch and to measure the applied forces during stretching in the rat model of moderate SCI. SETTING: Kentucky Spinal Cord Injury Research Center, Louisville, KY, USA. METHODS: Female Sprague Dawley rats (n = 4) were instrumented for telemetry-based EMG recording (right rectus femoris and biceps femoris) and received a moderate T10 spinal cord injury (SCI). The major hindlimb muscle groups were stretched using our clinically modeled protocol. The EMG responses were recorded biweekly for 8 weeks. The forces applied during stretching were measured using a custom designed glove. Locomotor function was assessed using the BBB Open Field Locomotor Scale, 3D kinematics and gait analysis. RESULTS: Three main EMG patterns in response to stretch were identified: clonic-like, air-stepping, and spasms. Torques applied during stretching ranged from 0.4-8 N*cm, and with the exception of the quadriceps, did not change significantly over the weeks of stretching. Two stretching sessions a week did not result in a significant disruption to locomotor function. CONCLUSIONS: Stretching evokes EMG patterns in rats similar to those reported in humans including clonus and spasms. The torques used during stretching are comparable, based on the ratio of torque to body weight, to the few previously published studies that measured the forces and/or torques applied by physical therapists when stretching patients. Future studies are warranted to fully explore the impact of muscle stretch on spinal cord function after injury. SPONSORSHIP: DoD, KSCHIRT, NIH.

AB - Children diagnosed with Long-Chain-3-Hydroxy-Acyl-CoA-Dehydrogenase-Deficiency (LCHADD) or Very-Long-Chain-3-Hydroxy-Acyl-CoA-Dehydrogenase-Deficiency (VLCADD) frequently present with hypertrophic cardiomyopathy or muscle weakness which is caused by the accumulation of fatty acid metabolites due to inactivating mutations in the mitochondrial trifunctional protein. By analyzing mitochondrial morphology we uncovered that mutations within the HADHA or the ACADVL gene not only affect fatty acid oxidation, but also cause significant changes in the DNM1L/MFN2 ratio leading to the significant accumulation of truncated and punctate mitochondria in contrast to network-like mitochondrial morphology in controls. These striking morphological abnormalities correlate with changes in OXPHOS, an imbalance in ROS levels, reduced mitochondrial respiration, reduced growth rates and significantly increased glucose uptake per cell, suggesting that HADHA and ACADVL mutations shift cellular energy household into glycolysis. Experiments using the NOX2-specific inhibitor Phox-I2 suggest that NOX2 is activated by accumulating long-chain fatty acids and generates ROS, which in turn changes mitochondrial morphology and activity. We thereby provide novel insights into the cellular energy household of cells from LCHADD/VLCADD patients and demonstrate for the first time a connection between fatty acid metabolism, mitochondrial morphology and ROS in patients with these rare genetic disorders.

AB - The interplay among ferroelectric, magnetic and elastic degrees of freedom in multiferroics is the key issues in condensed matters, which has been widely investigated by various methods. Here, using ultrafast two-color pump-probe spectroscopy, the picosecond electron-phonon and spin-lattice coupling process in Dysprosium doped-BiFeO3 (BDFO) films on SrTiO3 (STO) substrate have been investigated systematically. The Dy-doping induced structural transition and magnetic enhancement in BDFO is observed by ultrafast electron-phonon and spin lattice interaction, respectively. The elastic anomalies in BDFO films are revealed by the photo-induced coherent acoustic phonon. With increasing the Dy doping ratio, the frequencies of the acoustic phonon in the films are modulated, and the phonon transmission coefficient between films and substrate is found to approach unity gradually. The ultrafast observation of the tunability of the ferroelectric, magnetic and the elastic properties in the morphotropic phase boundary of rare-earth doped BFO films provides new insights into the integration of BFO in next-generation high frequency electro-magnetic and electroacoustic devices.

AB - Small interfering RNAs (siRNAs) conjugated to a trivalent N-acetylgalactosamine (GalNAc) ligand are being evaluated in investigational clinical studies for a variety of indications. The typical development candidate selection process includes evaluation of the most active compounds for toxicity in rats at pharmacologically exaggerated doses. The subset of GalNAc-siRNAs that show rat hepatotoxicity is not advanced to clinical development. Potential mechanisms of hepatotoxicity can be associated with the intracellular accumulation of oligonucleotides and their metabolites, RNA interference (RNAi)-mediated hybridization-based off-target effects, and/or perturbation of endogenous RNAi pathways. Here we show that rodent hepatotoxicity observed at supratherapeutic exposures can be largely attributed to RNAi-mediated off-target effects, but not chemical modifications or the perturbation of RNAi pathways. Furthermore, these off-target effects can be mitigated by modulating seed-pairing using a thermally destabilizing chemical modification, which significantly improves the safety profile of a GalNAc-siRNA in rat and may minimize the occurrence of hepatotoxic siRNAs across species. PMID- 29459661 TI - Elements of the complete blood count associated with cardiovascular disease incidence: Findings from the EPIC-NL cohort study. AB - All blood cells (white blood cells [WBC], red blood cells [RBC] and platelets) can play a role in atherosclerosis. Complete blood count (CBC) is widely available in clinical practice but utility as potential risk factors for cardiovascular disease (CVD) is uncertain. Our aim was to assess the associations of pre-diagnostic CBC with incidence of CVD in 14,362 adults free of CVD and aged 47.8 (+/-11.7) years at baseline, followed-up for 11.4 years (992 incident cases). Cox proportional hazards regressions were used to estimate HRs and 95%CI. Comparing the top (T3) to bottom (T1) tertile, increased total WBC, lymphocyte, monocyte and neutrophil counts were associated with higher CVD risk: 1.31 (1.10; 1.55), 1.20 (1.02; 1.41), 1.21 (1.03; 1.41) and 1.24 (1.05; 1.47), as well as mean corpuscular volume (MCV: 1.23 [1.04; 1.46]) and red cell distribution width (RDW: 1.22 [1.03; 1.44]). Platelets displayed an association for count values above the clinically normal range: 1.49 (1.00; 2.22). To conclude, total and differential WBC count, MCV, RDW and platelet count likely play a role in the aetiology of CVD but only WBC provide a modest improvement for the prediction of 10-year CVD risk over traditional CVD risk factors in a general population. PMID- 29459662 TI - Blast phase myeloproliferative neoplasm: Mayo-AGIMM study of 410 patients from two separate cohorts. AB - A total of 410 patients with blast phase myeloproliferative neoplasm (MPN-BP) were retrospectively reviewed: 248 from the Mayo Clinic and 162 from Italy. Median survival was 3.6 months, with no improvement over the last 15 years. Multivariable analysis performed on the Mayo cohort identified high risk karyotype, platelet count < 100 * 109/L, age > 65 years and transfusion need as independent risk factors for survival. Also in the Mayo cohort, intensive chemotherapy resulted in complete remission (CR) or CR with incomplete count recovery (CRi) rates of 35 and 24%, respectively; treatment-specified 3-year/5 year survival rates were 32/10% for patients receiving allogeneic stem cell transplant (AlloSCT) (n = 24), 19/13% for patients achieving CR/CRi but were not transplanted (n = 24), and 1/1% in the absence of both AlloSCT and CR/CRi (n = 200) (p < 0.01). The survival impact of AlloSCT (HR 0.2, 95% CI 0.1-0.3), CR/CRi without AlloSCT (HR 0.3, 95% CI 0.2-0.5), high risk karyotype (HR 1.6, 95% CI 1.1 2.2) and platelet count < 100 * 109/L (HR 1.6, 95% CI 1.1-2.2) were confirmed to be inter-independent. Similar observations were made in the Italian cohort. The current study identifies the setting for improved short-term survival in MPN-BP, but also highlights the limited value of current therapy, including AlloSCT, in securing long-term survival.

AB - We report on the tunable edge-plasmon-enhanced absorption of phosphorene nanoribbons supported on a dielectric substrate. Monolayer anisotropic black phosphorous (phosphorene) nanoribbons are explored for light trapping and absorption enhancement on different dielectric substrates. We show that these phosphorene ribbons support infrared surface plasmons with high spatial confinement. The peak position and bandwidth of the calculated phosphorene absorption spectra are tunable with low loss over a wide wavelength range via the surrounding dielectric environment of the periodic nanoribbons. Simulation results show strong edge plasmon modes and enhanced absorption as well as a red shift of the peak resonance wavelength. The periodic Fabry-Perot grating model was used to analytically evaluate the absorption resonance arising from the edge of the ribbons for comparison with the simulation. The results show promise for the promotion of phosphorene plasmons for both fundamental studies and potential applications in the infrared spectral range. PMID- 29459665 TI - A randomized, placebo-controlled pilot trial of aprepitant combined with standard antiemetic therapy for the prevention of chemotherapy-induced nausea and vomiting in patients undergoing cyclophosphamide-based conditioning regimens prior to hematopoietic stem cell transplant (HSCT). AB - The aim of this study was to evaluate the safety and efficacy of aprepitant when used prophylactically to prevent nausea and vomiting during cyclophosphamide based conditioning regimens. The primary objective of this study was to determine if there was a difference in the number of emesis-free days in patients who received aprepitant as compared to those who received placebo. This prospective, randomized, double blind, placebo-controlled study was performed in 40 adult patients who received a cyclophosphamide-containing HSCT conditioning regimen. Twenty patients were randomized to receive aprepitant, ondansetron, and dexamethasone, and 20 were randomized to receive placebo, ondansetron, and dexamethasone. Complete response (CR) was defined as the absence of emesis and the absence of mild to moderate nausea. The average number of emesis-free days was 14.25 (standard deviation 1.48 days) in the aprepitant group compared to 12.45 days (standard deviation 2.16 days) for patients in the placebo group. Eight patients (40%) in the aprepitant group achieved CR as compared to four patients (20%) in the placebo group. In the setting of cyclophosphamide containing conditioning regimens, the addition of aprepitant to a standard antiemetic regimen decreased the incidence of emesis as compared to placebo. Aprepitant was well tolerated. PMID- 29459664 TI - The putative anti-leukemic effects of anti-thymocyte globulins in patients with CD7-positive acute myeloid leukemia. AB - Polyclonal anti-thymocyte globulins (ATGs) are widely used in allogeneic stem cell transplantation (allo-SCT) for GvHD prophylaxis. ATGs exerted anti-tumor effects in in vitro experiments, but in vivo studies are lacking. We experienced a case of relapsed AML with cells positive for CD7 who underwent haploidentical SCT and unexpectedly achieved a significant reduction of AML cells in the peripheral blood after receiving ATGs before the administration of other drugs in the conditioning regimen. This patient achieved long-term survival after haploidentical SCT. To assess the impact of ATGs on clinical outcomes in patients with AML, we performed a retrospective analysis of allo-SCT for relapsed/refractory AML and divided 132 patients into four groups according to the expression of CD7 in AML cells and use of ATGs as part of the conditioning regimen, as follows: CD7-positive ATG group (n = 15), CD7-positive no-ATG group (n = 32), CD7-negative ATG group (n = 19), and CD7-negative no-ATG group (n = 66). The overall survival rates in the CD7-positive ATG group were significantly higher than those in the CD7-positive no-ATG group, whereas these rates did not differ statistically between the CD7-negative ATG and CD7-negative no-ATG groups. Our results indicate a possible anti-leukemic effect of ATGs against CD7-positive AML in humans.

AB - Biogenic sources contribute to cloud condensation nuclei (CCN) in the clean marine atmosphere, but few measurements exist to constrain climate model simulations of their importance. The chemical composition of individual atmospheric aerosol particles showed two types of sulfate-containing particles in clean marine air masses in addition to mass-based Estimated Salt particles. Both types of sulfate particles lack combustion tracers and correlate, for some conditions, to atmospheric or seawater dimethyl sulfide (DMS) concentrations, which means their source was largely biogenic. The first type is identified as New Sulfate because their large sulfate mass fraction (63% sulfate) and association with entrainment conditions means they could have formed by nucleation in the free troposphere. The second type is Added Sulfate particles (38% sulfate), because they are preexisting particles onto which additional sulfate condensed. New Sulfate particles accounted for 31% (7 cm-3) and 33% (36 cm-3) CCN at 0.1% supersaturation in late-autumn and late-spring, respectively, whereas sea spray provided 55% (13 cm-3) in late-autumn but only 4% (4 cm-3) in late-spring. Our results show a clear seasonal difference in the marine CCN budget, which illustrates how important phytoplankton-produced DMS emissions are for CCN in the North Atlantic. PMID- 29459667 TI - Expedient syntheses of N-heterocycles via intermolecular amphoteric diamination of allenes. AB - Saturated 1,4-diazo heterocycles including piperazines, 1,4-diazepanes, and 1,4 diazocanes, are highly important for therapeutic development, but their syntheses are often tedious. We describe here an amphoteric diamination strategy to unite readily available 1,2-, 1,3- or 1,4-diamine derivatives with electron-deficient allenes via a formal [n + 2] (n = 4, 5, 6) cyclization mode to produce the corresponding 1,4-diazo heterocycles in just one step. This strategy features mild reaction conditions, high functional group tolerance, and scalability (gram scale). The reagents used are cheap and readily available and no transition metal catalysts are needed. More sophisticated products containing trifluoromethyl group or bicyclic ring systems can be accessed via a one-pot procedure as well. Our mechanistic studies support that formation of mono-iodinated or chlorinated diamine intermediates is important for the desired transformation and the commonly proposed chloride-iodide exchange process and a radical N-C bond formation is unlikely when the combination of NCS/KI is used. PMID- 29459668 TI - Photoconductivity of acid exfoliated and flash-light-processed MoS2 films. AB - MoS2 has been studied intensively during recent years as a semiconducting material in several fields, including optoelectronics, for applications such as solar cells and phototransistors. The photoresponse mechanisms of MoS2 have been discussed but are not fully understood, especially the phenomenon in which the photocurrent slowly increases. Here, we report on a study of the photoresponse flash-light-processed MoS2 films of different thicknesses and areas. The photoresponse of such films under different light intensities and bias voltages was measured, showing significant current changes with a quick response followed by a slow one upon exposure to pulsed light. Our in-depth study suggested that the slow response was due to the photothermal effect that heats the MoS2; this hypothesis was supported by the resistivity change at different temperatures. The results obtained from MoS2 films with various thicknesses indicated that the minority-carrier diffusion length was 1.36 um. This study explained the mechanism of the slow response of the MoS2 film and determined the effective thickness of MoS2 for a photoresponse to occur. The method used here for fabricating MoS2 films could be used for fabricating optoelectronic devices due to its simplicity. PMID- 29459669 TI - Isoniazid resistance levels of Mycobacterium tuberculosis can largely be predicted by high-confidence resistance-conferring mutations. AB - The majority of Mycobacterium tuberculosis isolates resistant to isoniazid harbour a mutation in katG. Since these mutations cause a wide range of minimum inhibitory concentrations (MICs), largely below the serum level reached with higher dosing (15 mg/L upon 15-20 mg/kg), the drug might still remain partly active in presence of a katG mutation. We therefore investigated which genetic mutations predict the level of phenotypic isoniazid resistance in clinical M. tuberculosis isolates. To this end, the association between known and unknown isoniazid resistance-conferring mutations in whole genome sequences, and the isoniazid MICs of 176 isolates was examined. We found mostly moderate-level resistance characterized by a mode of 6.4 mg/L for the very common katG Ser315Thr mutation, and always very high MICs (>=19.2 mg/L) for the combination of katG Ser315Thr and inhA c-15t. Contrary to common belief, isolates harbouring inhA c 15t alone, partly also showed moderate-level resistance, particularly when combined with inhA Ser94Ala. No overt association between low-confidence or unknown mutations, except in katG, and isoniazid resistance (level) was found. Except for the rare katG deletion, line probe assay is thus not sufficiently accurate to predict the level of isoniazid resistance for a single mutation in katG or inhA. PMID- 29459670 TI - An unusual type of polymorphism in a liquid crystal. AB - Polymorphism is a remarkable concept in chemistry, materials science, computer science, and biology. Whether it is the ability of a material to exist in two or more crystal structures, a single interface connecting to two different entities, or alternative phenotypes of an organism, polymorphism determines function and properties. In materials science, polymorphism can be found in an impressively wide range of materials, including crystalline materials, minerals, metals, alloys, and polymers. Here we report on polymorphism in a liquid crystal. A bent core liquid crystal with a single chiral side chain forms two structurally and morphologically significantly different liquid crystal phases solely depending on the cooling rate from the isotropic liquid state. On slow cooling, the thermodynamically more stable oblique columnar phase forms, and on rapid cooling, a not heretofore reported helical microfilament phase. Since structure determines function and properties, the structural color for these phases also differs. PMID- 29459671 TI - In silico guided reconstruction and analysis of ICAM-1-binding var genes from Plasmodium falciparum. AB - The Plasmodium falciparum variant surface antigen PfEMP1 expressed on the surface of infected erythrocytes is thought to play a major role in the pathology of severe malaria. As the sequence pool of the var genes encoding PfEMP1 expands there are opportunities, despite the high degree of sequence diversity demonstrated by this gene family, to reconstruct full-length var genes from small sequence tags generated from patient isolates. To test whether this is possible we have used a set of recently laboratory adapted ICAM-1-binding parasite isolates to generate sequence tags and, from these, to identify the full-length PfEMP1 being expressed by them. In a subset of the strains available we were able to produce validated, full-length var gene sequences and use these to conduct biophysical analyses of the ICAM-1 binding regions. PMID- 29459672 TI - Route to high-energy density polymeric nitrogen t-N via He-N compounds. AB - Polymeric nitrogen, stabilized by compressing pure molecular nitrogen, has yet to be recovered to ambient conditions, precluding its application as a high-energy density material. Here we suggest a route for synthesis of a tetragonal polymeric nitrogen, denoted t-N, via He-N compounds at high pressures. Using first principles calculations with structure searching, we predict a class of nitrides with stoichiometry HeN4 that are energetically stable (relative to a mixture of solid He and N2) above 8.5 GPa. At high pressure, HeN4 comprises a polymeric channel-like nitrogen framework filled with linearly arranged helium atoms. The nitrogen framework persists to ambient pressure on decompression after removal of helium, forming pure polymeric nitrogen, t-N. t-N is dynamically and mechanically stable at ambient pressure with an estimated energy density of ~11.31 kJ/g, marking it out as a remarkable high-energy density material. This expands the known polymeric forms of nitrogen and indicates a route to its synthesis. PMID- 29459673 TI - Specific Recognition of Arginine Methylated Histone Tails by JMJD5 and JMJD7. AB - We have reported that JMJD5 and JMJD7 (JMJD5/7) are responsible for the clipping of arginine methylated histone tails to generate "tailless nucleosomes", which could release the pausing RNA polymerase II (Pol II) into productive transcription elongation. JMJD5/7 function as endopeptidases that cleave histone tails specifically adjacent to methylated arginine residues and continue to degrade N-terminal residues of histones via their aminopeptidase activity. Here, we report structural and biochemical studies on JMJD5/7 to understand the basis of substrate recognition and catalysis mechanism by this JmjC subfamily. Recognition between these enzymes and histone substrates is specific, which is reflected by the binding data between enzymes and substrates. High structural similarity between JMJD5 and JMJD7 is reflected by the shared common substrates and high binding affinity. However, JMJD5 does not bind to arginine methylated histone tails with additional lysine acetylation while JMJD7 does not bind to arginine methylated histone tails with additional lysine methylation. Furthermore, the complex structures of JMJD5 and arginine derivatives revealed a Tudor domain-like binding pocket to accommodate the methylated sidechain of arginine, but not lysine. There also exists a glutamine close to the catalytic center, which may suggest a unique imidic acid mediated catalytic mechanism for proteolysis by JMJD5/7. PMID- 29459674 TI - Identification of novel prognosis-related genes associated with cancer using integrative network analysis. AB - Prognosis identifies the seriousness and the chances of survival of a cancer patient. However, it remains a challenge to identify the key cancer genes in prognostic studies. In this study, we collected 2064 genes that were related to prognostic studies by using gene expression measurements curated from published literatures. Among them, 1820 genes were associated with copy number variations (CNVs). The further functional enrichment on 889 genes with frequent copy number gains (CNGs) revealed that these genes were significantly associated with cancer pathways including regulation of cell cycle, cell differentiation and mitogen activated protein kinase (MAPK) cascade. We further conducted integrative analyses of CNV and their target genes expression using the data from matched tumour samples of The Cancer Genome Atlas (TCGA). Ultimately, 95 key prognosis related genes were extracted, with concordant CNG events and increased up regulation in at least 300 tumour samples. These genes, and the number of samples in which they were found, included: ACTL6A (399), ATP6V1C1 (425), EBAG9 (412), FADD (308), MTDH (377), and SENP5 (304). This study provides the first observation of CNV in prognosis-related genes across pan-cancer. The systematic concordance between CNG and up-regulation of gene expression in these novel prognosis-related genes may indicate their prognostic significance. PMID- 29459675 TI - c-Jun N-terminal kinase 1 defective CD4+CD25+FoxP3+ cells prolong islet allograft survival in diabetic mice. AB - CD4+CD25+FoxP3+ cells (Tregs) inhibit inflammatory immune responses to allografts. Here, we found that co-transplantation of allogeneic pancreatic islets with Tregs that are defective in c-Jun N-terminal kinase 1 (JNK1) signaling prolongs islet allograft survival in the liver parenchyma of chemically induced diabetic mice (CDM). Adoptively transferred JNK1-/- but not wild-type (WT) Tregs survive longer in the liver parenchyma of CDM. JNK1-/- Tregs are resistant to apoptosis and express anti-apoptotic molecules. JNK1-/- Tregs express higher levels of lymphocyte activation gene-3 molecule (LAG-3) on their surface and produce higher amounts of the anti-inflammatory cytokine interleukin (IL)-10 compared with WT Tregs. JNK1-/- Tregs inhibit liver alloimmune responses more efficiently than WT Tregs. JNK1-/- but not WT Tregs are able to inhibit IL 17 and IL-21 production through enhanced LAG-3 expression and IL-10 production. Our study identifies a novel role of JNK1 signaling in Tregs that enhances islet allograft survival in the liver parenchyma of CDM. PMID- 29459676 TI - Genomic Variants in NEURL, GJA1 and CUX2 Significantly Increase Genetic Susceptibility to Atrial Fibrillation. AB - Atrial fibrillation (AF) is the most common arrhythmia. In 2014, two new meta GWAS identified 5 AF loci, including the NEURL locus, GJA1 locus, CAND2 locus, and TBX5 locus in the European ancestry populations and the NEURL locus and CUX2 locus in a Japanese population. The TBX5 locus for AF was reported by us in 2013 in the Chinese population. Here we assessed the association between AF and SNPs in the NEURL, GJA1, CAND2 and CUX2 loci in the Chinese Han population. We carried out a large case-control association study with 1,164 AF patients and 1,460 controls. Significant allelic and genotypic associations were identified between NEURL variant rs6584555 and GJA1 variant rs13216675 and AF. Significant genotypic association was found between CUX2 SNP rs6490029 and AF. No association was found between CAND2 variant rs4642101 and AF, which may be due to an insufficient power of the sample size for rs4642101. Together with our previous findings, seven of fifteen AF loci (<50%) identified by GWAS in the European ancestry populations conferred susceptibility to AF in the Chinese population, and explained approximately 14.5% of AF heritability. On the other hand, two AF loci identified in the Japanese population were both replicated in the Chinese population. PMID- 29459677 TI - A CRISPR-based screen for Hedgehog signaling provides insights into ciliary function and ciliopathies. AB - Primary cilia organize Hedgehog signaling and shape embryonic development, and their dysregulation is the unifying cause of ciliopathies. We conducted a functional genomic screen for Hedgehog signaling by engineering antibiotic-based selection of Hedgehog-responsive cells and applying genome-wide CRISPR-mediated gene disruption. The screen can robustly identify factors required for ciliary signaling with few false positives or false negatives. Characterization of hit genes uncovered novel components of several ciliary structures, including a protein complex that contains delta-tubulin and epsilon-tubulin and is required for centriole maintenance. The screen also provides an unbiased tool for classifying ciliopathies and showed that many congenital heart disorders are caused by loss of ciliary signaling. Collectively, our study enables a systematic analysis of ciliary function and of ciliopathies, and also defines a versatile platform for dissecting signaling pathways through CRISPR-based screening. PMID- 29459678 TI - Evolutionary analysis indicates that DNA alkylation damage is a byproduct of cytosine DNA methyltransferase activity. AB - Methylation at the 5 position of cytosine in DNA (5meC) is a key epigenetic mark in eukaryotes. Once introduced, 5meC can be maintained through DNA replication by the activity of 'maintenance' DNA methyltransferases (DNMTs). Despite their ancient origin, DNA methylation pathways differ widely across animals, such that 5meC is either confined to transcribed genes or lost altogether in several lineages. We used comparative epigenomics to investigate the evolution of DNA methylation. Although the model nematode Caenorhabditis elegans lacks DNA methylation, more basal nematodes retain cytosine DNA methylation, which is targeted to repeat loci. We found that DNA methylation coevolved with the DNA alkylation repair enzyme ALKB2 across eukaryotes. In addition, we found that DNMTs introduced the toxic lesion 3-methylcytosine into DNA both in vitro and in vivo. Alkylation damage is therefore intrinsically associated with DNMT activity, and this may promote the loss of DNA methylation in many species. PMID- 29459679 TI - Meta-analysis of genome-wide association studies for cattle stature identifies common genes that regulate body size in mammals. AB - Stature is affected by many polymorphisms of small effect in humans 1 . In contrast, variation in dogs, even within breeds, has been suggested to be largely due to variants in a small number of genes2,3. Here we use data from cattle to compare the genetic architecture of stature to those in humans and dogs. We conducted a meta-analysis for stature using 58,265 cattle from 17 populations with 25.4 million imputed whole-genome sequence variants. Results showed that the genetic architecture of stature in cattle is similar to that in humans, as the lead variants in 163 significantly associated genomic regions (P < 5 * 10-8) explained at most 13.8% of the phenotypic variance. Most of these variants were noncoding, including variants that were also expression quantitative trait loci (eQTLs) and in ChIP-seq peaks. There was significant overlap in loci for stature with humans and dogs, suggesting that a set of common genes regulates body size in mammals. PMID- 29459681 TI - Embryonic defects induced by maternal obesity in mice derive from Stella insufficiency in oocytes. AB - Maternal obesity can impair embryo development and offspring health, yet the mechanisms responsible remain poorly understood. In a high-fat diet (HFD)-based female mouse model of obesity, we identified a marked reduction of Stella (also known as DPPA3 or PGC7) protein in oocytes. Starting with this clue, we found that the establishment of pronuclear epigenetic asymmetry in zygotes from obese mice was severely disrupted, inducing the accumulation of maternal 5 hydroxymethylcytosine modifications and DNA lesions. Furthermore, methylome-wide sequencing analysis detected global hypomethylation across the zygote genome in HFD-fed mice, with a specific enrichment in transposon elements and unique regions. Notably, overexpression of Stella in the oocytes of HFD-fed mice not only restored the epigenetic remodeling in zygotes but also partly ameliorated the maternal-obesity-associated developmental defects in early embryos and fetal growth. Thus, Stella insufficiency in oocytes may represent a critical mechanism that mediates the phenotypic effects of maternal obesity in embryos and offspring. PMID- 29459680 TI - Genome-wide mapping of global-to-local genetic effects on human facial shape. AB - Genome-wide association scans of complex multipartite traits like the human face typically use preselected phenotypic measures. Here we report a data-driven approach to phenotyping facial shape at multiple levels of organization, allowing for an open-ended description of facial variation while preserving statistical power. In a sample of 2,329 persons of European ancestry, we identified 38 loci, 15 of which replicated in an independent European sample (n = 1,719). Four loci were completely new. For the others, additional support (n = 9) or pleiotropic effects (n = 2) were found in the literature, but the results reported here were further refined. All 15 replicated loci highlighted distinctive patterns of global-to-local genetic effects on facial shape and showed enrichment for active chromatin elements in human cranial neural crest cells, suggesting an early developmental origin of the facial variation captured. These results have implications for studies of facial genetics and other complex morphological traits.

Here, we describe cytochrome P450 monooxygenases from marine bacteria that, together with appropriate redox-partner proteins, catalyze the oxidative demethylation of 6-O-methyl-D-galactose, which is an abundant monosaccharide of the algal polysaccharides agarose and porphyran. This previously unknown biological function extends the group of carbohydrate-active enzymes to include the class of cytochrome P450 monooxygenases. PMID- 29459683 TI - Nano-Architecture of nitrogen-doped graphene films synthesized from a solid CN source. AB - New synthesis routes to tailor graphene properties by controlling the concentration and chemical configuration of dopants show great promise. Herein we report the direct reproducible synthesis of 2-3% nitrogen-doped 'few-layer' graphene from a solid state nitrogen carbide a-C:N source synthesized by femtosecond pulsed laser ablation. Analytical investigations, including synchrotron facilities, made it possible to identify the configuration and chemistry of the nitrogen-doped graphene films. Auger mapping successfully quantified the 2D distribution of the number of graphene layers over the surface, and hence offers a new original way to probe the architecture of graphene sheets. The films mainly consist in a Bernal ABA stacking three-layer architecture, with a layer number distribution ranging from 2 to 6. Nitrogen doping affects the charge carrier distribution but has no significant effects on the number of lattice defects or disorders, compared to undoped graphene synthetized in similar conditions. Pyridinic, quaternary and pyrrolic nitrogen are the dominant chemical configurations, pyridinic N being preponderant at the scale of the film architecture. This work opens highly promising perspectives for the development of self-organized nitrogen-doped graphene materials, as synthetized from solid carbon nitride, with various functionalities, and for the characterization of 2D materials using a significant new methodology. PMID- 29459685 TI - Reversible 90-Degree Rotation of Fe Magnetic Moment Using Hydrogen. AB - [Pd/Fe]2 multilayers were deposited on a flat MgO(001) to study the effect of hydrogen on magnetic interlayer coupling. Complex magnetic hysteresis behavior, including single, double, and triple loops, were measured as a function of the azimuthal angle in a longitudinal and transverse direction. With a combination of a 2-fold magnetic anisotropy energy (MAE) in the bottom-Fe and a 4-fold MAE in the top-Fe, the complex magnetic hysteresis behavior could be clearly explained. Two well-split hysteresis loops with almost zero Kerr remanence were measured by choosing a suitable Pd thickness and applying the magnetic field perpendicular to the easy axis of the bottom-Fe. The split double loops originated from the 90 degrees -rotation of the top-Fe moment. On exposure to a hydrogen gas atmosphere, the separation of the two minor loops increased, indicating that Pd-hydride formation enhanced the ferromagnetic coupling between the two Fe layers. Based on these observations, we proposed that, by applying a suitable constant magnetic field, the top-Fe moment could undergo reversible 90 degrees -rotation following hydrogen exposure. The results suggest that the Pd space layer used for mediating the magnetic interlayer coupling is sensitive to hydrogen, and therefore, the multilayer system can function as a giant magnetoresistance-type sensor suitable for hydrogen gas.

AB - The purpose of this study was to quantify the peri-operative blood loss of elderly patients with intertrochanteric fractures treated by unreamed proximal femoral nail anti-rotation (PFNA) and analyze whether the substantial hidden blood loss was induced by initial trauma or the operation. The clinical data of 123 patients with intertrochanteric fracture treated with unreamed PFNA from Jan 2013 to Apr 2017 were analyzed retrospectively. Blood routine on admission day (ADM), pre-operative day one (PRE), post-operative days one and three (POD1 and POD3) and the visible blood loss (VBL) were obtained. The total blood loss (TBL) from ADM to POD1 and POD3 were 693.5 +/- 359.6 ml and 863.8 +/- 429.9 ml, of which the corresponding hidden blood loss (HBL) was 86.8% and 89.4% respectively. The mean TBL and HBL from ADM to PRE (375.5 +/- 242.0 ml, 375.5 +/- 242.0 ml) were higher than that from PRE to POD1 (318.0 +/- 183.4 ml, 226.5 +/- 163.2 ml), p < 0.001 respectively. There was no significant difference between HBL from ADM to PRE and HBL from PRE to POD3 (375.5 +/- 242.0 ml, 396.7 +/- 254.0 ml, p = 0.361). The majority of peri-operative HBL occurred before surgery, it was mainly associated with the initial trauma rather than the operation. PMID- 29459686 TI - Long noncoding RNA Gomafu upregulates Foxo1 expression to promote hepatic insulin resistance by sponging miR-139-5p. AB - Long non-coding RNA Gomafu is involved in diabetes-related diseases. However, its role in insulin resistance (IR) remains unclear. Our objective is to explore the role of Gomafu in hepatic IR and glucose intolerance. Gomafu expression was determined in livers of ob/ob mice and high-fat diet (HFD) mice. The binding activity of NF-kappaB on the Gomafu promoter was measured by chromatin immunoprecipitation and quantitative real-time PCR assays. Increased Gomafu expression was observed in the livers of obese mice. Besides, the binding of NF kappaB on the Gomafu promoter was also observed in hepatocytes from ob/ob mice. Further study showed that knockdown of NF-kappaB p65 alleviated the increase in hepatic Gomafu expression in vivo and in vitro. Knockdown of hepatic Gomafu inhibited hepatic glucose production (HGP) and improved insulin sensitivity in obese mice, whereas, overexpression of hepatic Gomafu resulted in an increase in random and fasting blood glucose levels in lean mice. In addition, we demonstrated that Gomafu functioned as miR-139 sponge and led to the de repression of its target gene Foxo1, which played an important role in gluconeogenesis and HGP in hepatocytes. Finally, silenced Foxo1 expression abolished the effect of Gomafu overexpression on gluconeogenesis and glucose production in hepatocytes. Taken together, our data suggested that the increase in Gomafu expression contributed to hepatic IR in obese mice. PMID- 29459687 TI - Maturation State and Matrix Microstructure Regulate Interstitial Cell Migration in Dense Connective Tissues. AB - Few regenerative approaches exist for the treatment of injuries to adult dense connective tissues. Compared to fetal tissues, adult connective tissues are hypocellular and show limited healing after injury. We hypothesized that robust repair can occur in fetal tissues with an immature extracellular matrix (ECM) that is conducive to cell migration, and that this process fails in adults due to the biophysical barriers imposed by the mature ECM. Using the knee meniscus as a platform, we evaluated the evolving micromechanics and microstructure of fetal and adult tissues, and interrogated the interstitial migratory capacity of adult meniscal cells through fetal and adult tissue microenvironments with or without partial enzymatic digestion. To integrate our findings, a computational model was implemented to determine how changing biophysical parameters impact cell migration through these dense networks. Our results show that the micromechanics and microstructure of the adult meniscus ECM sterically hinder cell mobility, and that modulation of these ECM attributes via an exogenous matrix-degrading enzyme permits migration through this otherwise impenetrable network. By addressing the inherent limitations to repair imposed by the mature ECM, these studies may define new clinical strategies to promote repair of damaged dense connective tissues in adults. PMID- 29459688 TI - iTRAQ-based quantitative proteomic analysis reveals important metabolic pathways for arsenic-induced liver fibrosis in rats. AB - Long-term consumption of sodium arsenite contaminated water can cause endemic arsenic disease. The proteome profile changes of liver fibrosis after exposure to arsenite containing water remain unclear. In this study, Sprague-Dawley (SD) male rats were treated with sodium arsenite (iAs3+), using a daily dose of 1.36 mg/kg body weight (medium dose group, M), 2.73 mg/kg body weight (high dose group, H) or deionized water (control group, C). Isobaric tags for relative and absolute quantitation (iTRAQ) were used to identify the different abundant proteins (DAPs) after arsenic-induced liver fibrosis. A total of 2987 high-quality proteins were detected (95% confident peptides >= 2), 608 of which were differentially expressed (fold change > 2 and p < 0.05) in M group and 475 in H group. Moreover, 431 DAPs were found in both M and H groups and used in subsequent bioinformatic analyses. Gene ontology (GO) analysis revealed 4,709 GO terms could be mapped, among which purine binding, actin filament binding and protein kinase binding were the most enriched terms for molecular function category. In addition, protein-protein interaction analysis showed six clusters of interaction networks. Our data provided new insights into the proteome changes after arsenic-induced liver fibrosis in model rats. PMID- 29459689 TI - The value of hip circumference/heightx ratio for identifying childhood hypertension. AB - To investigate the value of hip circumference related indexes for identifying childhood hypertension. In 2011, 1,352 Han children aged 7-12 years were recruited in our study. Hypertension was defined as systolic blood pressure or diastolic blood pressure >=95th percentile for all three screenings. We set the power value of the hip circumference/heightx ratio (x = 0, 0.8, 1 and 1.5) and studied the association with blood pressure. Hip circumference, hip circumference/height0.8, hip circumference/height and hip circumference/height1.5 all showed a positive correlation with systolic blood pressure and diastolic blood pressure(P < 0.05). Area under the curve (AUC) was used to evaluate the abilities of hip circumference related indexes. Hip circumference/height0.8, hip circumference/height and hip circumference/height1.5 were not superior to hip circumference. The present study demonstrates that hip circumference measurement is a helpful tool to detect the presence of hypertension in Han children 7-12 years old. PMID- 29459690 TI - Scattering resonances in bimolecular collisions between NO radicals and H2 challenge the theoretical gold standard. AB - Over the last 25 years, the formalism known as coupled-cluster (CC) theory has emerged as the method of choice for the ab initio calculation of intermolecular interaction potentials. The implementation known as CCSD(T) is often referred to as the gold standard in quantum chemistry. It gives excellent agreement with experimental observations for a variety of energy-transfer processes in molecular collisions, and it is used to calibrate density functional theory. Here, we present measurements of low-energy collisions between NO radicals and H2 molecules with a resolution that challenges the most sophisticated quantum chemistry calculations at the CCSD(T) level. Using hitherto-unexplored anti seeding techniques to reduce the collision energy in a crossed-beam inelastic scattering experiment, a resonance structure near 14 cm-1 is clearly resolved in the state-to-state integral cross-section, and a unique resonance fingerprint is observed in the corresponding differential cross-section. This resonance structure discriminates between two NO-H2 potentials calculated at the CCSD(T) level and pushes the required accuracy beyond the gold standard. PMID- 29459691 TI - Observation of correlated excitations in bimolecular collisions. AB - Although collisions between atoms and molecules are largely understood, collisions between two molecules have proven much harder to study. In both experiment and theory, our ability to determine quantum-state-resolved bimolecular cross-sections lags behind their atom-molecule counterparts by decades. For many bimolecular systems, even rules of thumb-much less intuitive understanding-of scattering cross sections are lacking. Here, we report the measurement of state-to-state differential cross sections on the collision of state-selected and velocity-controlled nitric oxide (NO) radicals and oxygen (O2) molecules. Using velocity map imaging of the scattered NO radicals, the full product-pair correlations of rotational excitation that occurs in both collision partners from individual encounters are revealed. The correlated cross sections show surprisingly good agreement with quantum scattering calculations using ab initio NO-O2 potential energy surfaces. The observations show that the well-known energy-gap law that governs atom-molecule collisions does not generally apply to bimolecular excitation processes, and reveal a propensity rule for the vector correlation of product angular momenta. PMID- 29459692 TI - Isolation of uracil auxotroph mutants of coral symbiont alga for symbiosis studies. AB - Coral reef ecosystems rely on stable symbiotic relationship between the dinoflagellate Symbiodinium spp. and host cnidarian animals. The collapse of such symbiosis could cause coral 'bleaching' and subsequent host death. Despite huge interest on Symbiodinium, lack of mutant strains and readily available genetic tools have hampered molecular research. A major issue was the tolerance to marker antibiotics. Here, we isolated Symbiodinium mutants requiring uracil for growth, and hence, useful in transformation screening. We cultured Symbiodinium spp. cells in the presence of 5-fluoroorotic acid (5FOA), which inhibits the growth of cells expressing URA3 encoding orotidine-5'-monophosphate decarboxylase, and isolated cells that require uracil for growth. Sequence analyses and genetic complementation tests using yeast demonstrated that one of the mutant cell lines had a point mutation in URA3, resulting in a splicing error at an unusual exon intron junction, and consequently, loss of enzyme activity. This mutant could maintain a symbiotic relationship with the model sea anemone Exaiptasia pallida only in sea water containing uracil. Results show that the URA3 mutant will be a useful tool for screening Symbiodinium transformants, both ex and in hospite, as survival in the absence of uracil is possible only upon successful introduction of URA3. PMID- 29459693 TI - Identification and characterization of SSE15206, a microtubule depolymerizing agent that overcomes multidrug resistance. AB - Microtubules are highly dynamic structures that form spindle fibres during mitosis and are one of the most validated cancer targets. The success of drugs targeting microtubules, however, is often limited by the development of multidrug resistance. Here we describe the discovery and characterization of SSE15206, a pyrazolinethioamide derivative [3-phenyl-5-(3,4,5-trimethoxyphenyl)-4,5-dihydro 1H-pyrazole-1-carbothioamide] that has potent antiproliferative activities in cancer cell lines of different origins and overcomes resistance to microtubule targeting agents. Treatment of cells with SSE15206 causes aberrant mitosis resulting in G2/M arrest due to incomplete spindle formation, a phenotype often associated with drugs that interfere with microtubule dynamics. SSE15206 inhibits microtubule polymerization both in biochemical and cellular assays by binding to colchicine site in tubulin as shown by docking and competition studies. Prolonged treatment of cells with the compound results in apoptotic cell death [increased Poly (ADP-ribose) polymerase cleavage and Annexin V/PI staining] accompanied by p53 induction. More importantly, we demonstrate that SSE15206 is able to overcome resistance to chemotherapeutic drugs in different cancer cell lines including multidrug-resistant KB-V1 and A2780-Pac-Res cell lines overexpressing MDR-1, making it a promising hit for the lead optimization studies to target multidrug resistance. PMID- 29459694 TI - Human antibody responses against non-covalently cell wall-bound Staphylococcus aureus proteins. AB - Human antibody responses to pathogens, like Staphylococcus aureus, are important indicators for in vivo expression and immunogenicity of particular bacterial components. Accordingly, comparing the antibody responses to S. aureus components may serve to predict their potential applicability as antigens for vaccination. The present study was aimed at assessing immunoglobulin G (IgG) responses elicited by non-covalently cell surface-bound proteins of S. aureus, which thus far received relatively little attention. To this end, we applied plasma samples from patients with the genetic blistering disease epidermolysis bullosa (EB) and healthy S. aureus carriers. Of note, wounds of EB patients are highly colonized with S. aureus and accordingly these patients are more seriously exposed to staphylococcal antigens than healthy individuals. Ten non-covalently cell surface bound proteins of S. aureus, namely Atl, Eap, Efb, EMP, IsaA, LukG, LukH, SA0710, Sle1 and SsaA2, were selected by bioinformatics and biochemical approaches. These antigens were recombinantly expressed, purified and tested for specific IgG responses using human plasma. We show that high exposure of EB patients to S. aureus is mirrored by elevated IgG levels against all tested non-covalently cell wall-bound staphylococcal antigens. This implies that these S. aureus cell surface proteins are prime targets for the human immune system. PMID- 29459695 TI - Light action spectrum on oxidative stress and mitochondrial damage in A2E-loaded retinal pigment epithelium cells. AB - AIMS: Blue light is an identified risk factor for age-related macular degeneration (AMD). We investigated oxidative stress markers and mitochondrial changes in A2E-loaded retinal pigment epithelium cells under the blue-green part of the solar spectrum that reaches the retina to better understand the mechanisms underlying light-elicited toxicity. RESULTS: Primary retinal pigment epithelium cells were loaded with a retinal photosensitizer, AE2, to mimic aging. Using a custom-made illumination device that delivers 10 nm-wide light bands, we demonstrated that A2E-loaded RPE cells generated high levels of both hydrogen peroxide (H2O2) and superoxide anion (O2*-) when exposed to blue-violet light. In addition, they exhibited perinuclear clustering of mitochondria with a decrease of both their mitochondrial membrane potential and their respiratory activities. The increase of oxidative stress resulted in increased levels of the oxidized form of glutathione and decreased superoxide dismutase (SOD) and catalase activities. Furthermore, mRNA expression levels of the main antioxidant enzymes (SOD2, catalase, and GPX1) also decreased. CONCLUSIONS: Using an innovative illumination device, we measured the precise action spectrum of the oxidative stress mechanisms on A2E-loaded retinal pigment epithelium cells. We defined 415 455 nm blue-violet light, within the solar spectrum reaching the retina, to be the spectral band that generates the highest amount of reactive oxygen species and produces the highest level of mitochondrial dysfunction, explaining its toxic effect. This study further highlights the need to filter these wavelengths from the eyes of AMD patients. PMID- 29459696 TI - Null Model and Community Structure in Multiplex Networks. AB - The multiple relationships among objects in complex systems can be described well by multiplex networks, which contain rich information of the connections between objects. The null model of networks, which can be used to quantify the specific nature of a network, is a powerful tool for analysing the structural characteristics of complex systems. However, the null model for multiplex networks remains largely unexplored. In this paper, we propose a null model for multiplex networks based on the node redundancy degree, which is a natural measure for describing the multiple relationships in multiplex networks. Based on this model, we define the modularity of multiplex networks to study the community structures in multiplex networks and demonstrate our theory in practice through community detection in four real-world networks. The results show that our model can reveal the community structures in multiplex networks and indicate that our null model is a useful approach for providing new insights into the specific nature of multiplex networks, which are difficult to quantify. PMID- 29459698 TI - Identification of a locus conferring dominant resistance to maize rough dwarf disease in maize. AB - Maize rough dwarf disease (MRDD) is a severe viral disease of maize that occurs worldwide, particularly in the summer maize-growing areas in China, resulting in yield losses and quality deterioration in susceptible maize varieties. An effective solution to control MRDD is to use resistance genes to improve the behavior of susceptible genotypes. Here, we employed maize F2 populations derived from a cross between susceptible line S221 and resistant line K36 for the deep sequencing of the two DNA pools containing extremely resistant and susceptible F2 individuals, and used traditional linkage analysis to locate the resistance related genomic region. The results showed that MRDD resistance in K36 was controlled by a single dominant locus, and an associated region was identified within the genomic interval of 68,396,487 bp and 69,523,478 bp on chromosome 6. Two simple sequence repeat (SSR) markers 6F29R29 and 6F34R34 were tightly linked to the MRDD resistance locus. The findings of the present study improve our understanding of the inheritance patterns of MRDD resistance, and should inform MRDD-resistant maize breeding programs. PMID- 29459697 TI - Serum Metabolomics of Activity Energy Expenditure and its Relation to Metabolic Syndrome and Obesity. AB - Modifiable lifestyle factors, including exercise and activity energy expenditure (AEE), may attenuate the unfavorable health effects of obesity, such as risk factors of metabolic syndrome (MetS). However, the underlying mechanisms are not clear. In this study we sought to investigate whether the metabolite profiles of MetS and adiposity assessed by body mass index (BMI) and central obesity are inversely correlated with AEE and physical activity. We studied 35 men and 47 women, aged 30-60 years, using doubly labeled water to derive AEE and the Sedentary Time and Activity Reporting Questionnaire (STAR-Q) to determine the time spent in moderate and vigorous physical activity. Proton nuclear magnetic resonance spectroscopy was used for serum metabolomics analysis. Serine and glycine were found in lower concentrations in participants with more MetS risk factors and greater adiposity. However, serine and glycine concentrations were higher with increasing activity measures. Metabolic pathway analysis and recent literature suggests that the lower serine and glycine concentrations in the overweight/obese state could be a consequence of serine entering de novo sphingolipid synthesis. Taken together, higher levels of AEE and physical activity may play a crucial part in improving metabolic health in men and women with and without MetS risk factors. PMID- 29459699 TI - Homogenization and impoverishment of taxonomic and functional diversity of ants in Eucalyptus plantations. AB - Despite its negative impacts on the environment and biodiversity, tree plantations can contribute to biodiversity conservation in fragmented landscapes, as they harbor many native species. In this study, we investigated the impact of Eucalyptus plantations on the taxonomic and functional diversity of ant communities, comparing ant communities sampled in managed and unmanaged (abandoned for 28 years) Eucalyptus plantations, and native Atlantic rain forests. Eucalyptus plantations, both managed and unmanaged, reduced the functional diversity and increased the similarity between ant communities leading to functional homogenization. While communities in managed plantations had the lowest values of both taxonomic and functional ant diversities, ant communities from unmanaged plantations had similar values of species richness, functional redundancy and Rao's Q compared to ant communities from forest patches (although functional richness was lower). In addition, communities in unmanaged Eucalyptus plantations were taxonomically and functionally more similar to communities located in managed plantations, indicating that Eucalyptus plantations have a severe long-term impact on ant communities. These results indicate that natural regeneration may mitigate the impact of Eucalyptus management, particularly regarding the functional structure of the community (alpha diversity), although it does not attenuate the effects of long term homogenization in community composition (beta diversity). PMID- 29459700 TI - Split spawning realigns coral reproduction with optimal environmental windows. AB - Split spawning in coral populations occurs when gamete maturation and mass spawning are split over two consecutive months. While split spawning has been observed at many reefs, little is known about the frequency and significance of these events. Here we show that split spawning occurred frequently and predictably over a decade at Scott Reef. Split spawning overlays the biannual spawning pattern in the region and occurs when the full moon falls in the first week of the usual spawning month, or the last week of the previous month. Additionally, in split years most species have their main spawning event after a 13-month lunar cycle, in the month following the usual spawning month. Without split spawning, spawn dates would shift by ~10 days each year to occur outside of optimal environmental windows. Our results suggest that split spawning is driven by a disconnect between lunar and seasonal cues, and is analogous with a 'leap year' in coral reproduction, realigning spawning dates with favourable conditions for reproduction. PMID- 29459702 TI - QFMatch: multidimensional flow and mass cytometry samples alignment. AB - Part of the flow/mass cytometry data analysis process is aligning (matching) cell subsets between relevant samples. Current methods address this cluster-matching problem in ways that are either computationally expensive, affected by the curse of dimensionality, or fail when population patterns significantly vary between samples. Here, we introduce a quadratic form (QF)-based cluster matching algorithm (QFMatch) that is computationally efficient and accommodates cases where population locations differ significantly (or even disappear or appear) from sample to sample. We demonstrate the effectiveness of QFMatch by evaluating sample datasets from immunology studies. The algorithm is based on a novel multivariate extension of the quadratic form distance for the comparison of flow cytometry data sets. We show that this QF distance has attractive computational and statistical properties that make it well suited for analysis tasks that involve the comparison of flow/mass cytometry samples. PMID- 29459701 TI - Imaging of electrical activity in small diameter fibers of the murine peripheral nerve with virally-delivered GCaMP6f. AB - Current neural interfaces are hampered by lack of specificity and selectivity for neural interrogation. A method that might improve these interfaces is an optical peripheral nerve interface which communicates with individual axons via optogenetic reporters. To determine the feasibility of such an interface, we delivered the genetically encoded calcium indicator GCaMP6f to the mouse peripheral nerve by intramuscular injection of adenoassociated viral vector (AAV1) under the control of the CAG (chicken beta actin- cytomegalovirus hybrid promoter). Small diameter axons in the common peroneal nerve were transduced and demonstrated electrically inducible calcium transients ex vivo. Responses to single electrical stimuli were resolvable, and increasing the number of stimuli resulted in a monotonic increase in maximum fluorescence and a prolongation of calcium transient kinetics. This work demonstrates the viability of using a virally-delivered, genetically-encoded calcium indicator to read-out from peripheral nerve axons. PMID- 29459703 TI - Investigation on the role of surfactants in bubble-algae interaction in flotation harvesting of Chlorella vulgaris. AB - In this work, a fundamental study was carried out on the role of surfactants in bubble-algae interaction to improve the understanding of how surfactants influence the flotation performance. Flotation tests for harvesting Chlorella vulgaris were first conducted using two surfactants, hexadecyltrimethyl ammonium bromide (C16TAB) and tea saponin. The effect of surfactants on harvesting efficiency was found to depend on their type and concentration. The present results also indicated that C16TAB exhibited higher harvesting efficiency than tea saponin. The adsorption experiments of surfactants onto C. vulgaris and the characterization measurements of algae surface were then carried out to reveal underlying interaction mechanisms between surfactants and algae in air flotation process. The results confirmed the adsorption process of surfactants onto C. vulgaris was feasible, spontaneous and endothermic. Subsequently, two mechanism models were proposed to qualitatively establish the interaction relationship among algae, surfactants and bubbles in the flotation. According to two models, C16TAB could neutralize the algal potential, while tea saponin converted algal surface from hydrophilic into hydrophobic. Overall, two surfactants used here could facilitate attachment of C. vulgaris onto bubbles, making the algae easier to be harvested, thereby increasing the flotation recovery. PMID- 29459704 TI - Initial meconium microbiome in Chinese neonates delivered naturally or by cesarean section. AB - Previous studies have revealed significant differences in microbiome compositions between infants delivered via cesarean section (C-section) and natural vaginal birth. However, the importance of the delivery mode in the first days of life remains unclear. Importantly, this stage is minimally affected by infant feeding. Here, we used a metagenomic sequencing technique to characterize the meconium microbiome from the feces of a Chinese cohort of vaginally and C-section delivered infants, including in vitro fertilization (IVF) newborns, during the first 24 h after birth. Meconium microbiome diversity was higher in vaginally delivered infants than that in C-section-delivered infants. Propionibacterium species were most abundant in the vaginally delivered infants, whereas the C section group had high levels of Bacillus licheniformis. The two IVF newborns delivered by C-section harbored microbial communities similar to the vaginal microbiome in terms of taxonomic composition. Metabolic functions of the C section group suffered more from the influence of the dominant group (B. licheniformis), whereas the vaginal group was more homogeneous, with a metabolism dominated by multi-microbes. Moreover, different modes of delivery affected the antibiotic resistance gene (ARG) prevalence. These findings provide novel information for the development of strategies to guide a healthy mode of delivery and promote the formation of healthy microbiota. PMID- 29459705 TI - Duplication resolves conflict. PMID- 29459706 TI - Gene-based predictive models of trophic modes suggest Asgard archaea are not phagocytotic. AB - With the current explosion of genomic data, there is a greater need to draw inference on phenotypic information based on DNA sequence alone. We considered complete genomes from 35 diverse eukaryotic lineages, and discovered sets of proteins predictive of trophic mode, including a set of 485 proteins that are enriched among phagocytotic eukaryotes (organisms that internalize large particles). Our model is also predictive of other aspects of trophic mode, including photosynthesis and the ability to synthesize a set of organic compounds needed for growth (prototrophy for those molecules). We applied our model to the Asgard archaea, a group of uncultured microorganisms that show close affinities to eukaryotes, to test whether the organisms are capable of phagocytosis, a phenotypic trait often considered a prerequisite for mitochondrial acquisition. Our analyses suggest that members of the Asgard archaea-despite having some eukaryote-specific protein families not found in other prokaryotes-do not use phagocytosis. Moreover, our data suggest that the process of phagocytosis arose from a combination of both archaeal and bacterial components, but also required additional eukaryote-specific innovations. PMID- 29459708 TI - Patterns of shared signatures of recent positive selection across human populations. AB - Signatures of recent positive selection often overlap across human populations, but the question of how often these overlaps represent a single ancestral event remains unresolved. If a single selective event spread across many populations, the same sweeping haplotype should appear in each population and the selective pressure could be common across populations and environments. Identifying such shared selective events could identify genomic loci and human traits important in recent history across the globe. In addition, genomic annotations that recently became available could help attach these signatures to a potential gene and molecular phenotype selected across populations. Here, we present a catalogue of selective sweeps in humans, and identify those that overlap and share a sweeping haplotype. We connect these sweep overlaps with potential biological mechanisms at several loci, including potential new sites of adaptive introgression, the glycophorin locus associated with malarial resistance and the alcohol dehydrogenase cluster associated with alcohol dependency. PMID- 29459707 TI - Hologenomic adaptations underlying the evolution of sanguivory in the common vampire bat. AB - Adaptation to specialized diets often requires modifications at both genomic and microbiome levels. We applied a hologenomic approach to the common vampire bat (Desmodus rotundus), one of the only three obligate blood-feeding (sanguivorous) mammals, to study the evolution of its complex dietary adaptation. Specifically, we assembled its high-quality reference genome (scaffold N50 = 26.9 Mb, contig N50 = 36.6 kb) and gut metagenome, and compared them against those of insectivorous, frugivorous and carnivorous bats. Our analyses showed a particular common vampire bat genomic landscape regarding integrated viral elements, a dietary and phylogenetic influence on gut microbiome taxonomic and functional profiles, and that both genetic elements harbour key traits related to the nutritional (for example, vitamin and lipid shortage) and non-nutritional (for example, nitrogen waste and osmotic homeostasis) challenges of sanguivory. These findings highlight the value of a holistic study of both the host and its microbiota when attempting to decipher adaptations underlying radical dietary lifestyles. PMID- 29459710 TI - Lack of support for adaptation of post-glacial horses to woodlands. PMID- 29459709 TI - Gene duplicates resolving sexual conflict rapidly evolved essential gametogenesis functions. AB - Males and females have different fitness optima but share the vast majority of their genomes, causing an inherent genetic conflict between the two sexes that must be resolved to achieve maximal population fitness. We show that two tandem duplicate genes found specifically in Drosophila melanogaster are sexually antagonistic, but rapidly evolved sex-specific functions and expression patterns that mitigate their antagonistic effects. We use copy-specific knockouts and rescue experiments to show that Apollo (Apl) is essential for male fertility but detrimental to female fertility, in addition to its important role in development, while Artemis (Arts) is essential for female fertility but detrimental to male fertility. Further analyses show that Apl and Arts have essential roles in spermatogenesis and oogenesis. These duplicates formed ~200,000 years ago, underwent a strong selective sweep and lost most expression in the antagonized sex. These data provide direct evidence that gene duplication allowed rapid mitigation of sexual conflict by allowing Apl and Arts to evolve essential sex-specific reproductive functions and complementary expression in male and female gonads. PMID- 29459711 TI - Broadband terahertz absorber based on multi-band continuous plasmon resonances in geometrically gradient dielectric-loaded graphene plasmon structure. AB - We propose a broadband terahertz absorber consisting of nonstructured graphene loaded with arrays of elliptic dielectric cylinders. The relative bandwidth for the absorption above 90% reaches about 65%. The working mechanism of broad bandwidth mainly comes from two aspects. One is that the nonstructured graphene loaded with elliptic dielectric cylinders provides multiple discrete graphene plasmon resonances with large relative frequency interval. The other is that, for each discrete resonance, there exists a set of continuous plasmon resonances because the width of the dielectric structure varies continuously and gradiently. The broadband terahertz absorber we demonstrate here, based on geometrically gradient dielectric structures and nonstructured graphene, avoids the graphene processing, which shows great potential applications in related devices. PMID- 29459712 TI - The E3 ubiquitin ligase Triad1 influences development of Mll-Ell-induced acute myeloid leukemia. AB - Chromosomal translocations involving the MLL1 gene characterize a poor prognosis subset of acute myeloid leukemia (AML), referred to as 11q23-AML. Transcription of the HOXA9 and HOXA10 genes is enhanced in hematopoietic stem and progenitor cells in these leukemias. We previously found the ARIH2 gene was repressed by HoxA9 in myeloid progenitors, but activated by HoxA10 during granulopoiesis. ARIH2 encodes the Triad1 protein, an anti-proliferative E3 ubiquitin ligase. In the current study, we investigate the role of Triad1 in leukemogenesis induced by an MLL1 fusion protein (Mll-Ell). We found Mll-Ell increased expression of HoxA9, HoxA10, and Triad1 because HoxA9 represses only one of two ARIH2 cis elements that are activated by HoxA10. Although Triad1 antagonized the generally pro proliferative effects of the Mll-Ell oncoprotein, we found blocking HoxA9 and HoxA10 phosphorylation shifted the balance to ARIH2 repression in Mll-Ell+ cells. We investigated the significance of these in vitro results in a murine bone marrow transplant model. We found Triad1 knockdown significantly shortened the latency to development of AML in mice transplanted with Mll-Ell-transduced bone marrow. And, Triad1 expression fell during the prolonged AML latency period in mice transplanted with bone marrow expressing Mll-Ell alone. Our studies identify Triad1 as a leukemia suppressor in 11q23-AML. This suggests defining relevant Triad1 substrates may indicate novel therapeutic targets in this disease. PMID- 29459713 TI - Elevated mitochondrial SLC25A29 in cancer modulates metabolic status by increasing mitochondria-derived nitric oxide. AB - Warburg effect has been recognized as a hallmark of cancer cells for many years, but its modulation mechanism remains a great focus. Our current study found a member of solute carrier family 25 (SLC25A29), the main arginine transporter on mitochondria, significantly elevated in various cancer cells. Knockout of SLC25A29 by CRISPR/Cas9 inhibited proliferation and migration of cancer cells both in vitro and in vivo. SLC25A29-knockout cells also showed an altered metabolic status with enhanced mitochondrial respiration and reduced glycolysis. All of above impacts could be reversed after rescuing SLC25A29 expression in SLC25A29-knockout cells. Arginine is transported into mitochondria partly for nitric oxide (NO) synthesis. Deletion of SLC25A29 resulted in severe decrease of NO production, indicating that the mitochondria is a significant source of NO. SLC25A29-knockout cells dramatically altered the variation of metabolic processes, whereas addition of arginine failed to reverse the effect, highlighting the necessity of transporting arginine into mitochondria by SLC25A29. In conclusion, aberrant elevated SLC25A29 in cancer functioned to transport more arginine into mitochondria, improved mitochondria-derived NO levels, thus modulated metabolic status to facilitate increased cancer progression. PMID- 29459715 TI - Saliva as a medium to detect and measure biomarkers related to pain. AB - Saliva is often neglected as a body fluid of diagnostic or prognostic value, even though generally well accepted by the patients. This is due to lack of a standardized collection procedure. The aim of this study was to identify the ideal saliva collection technique and develop new sensitive methods to detect and analyse markers related to pain in healthy pain-free subjects. Plasma and five different saliva collection approached was evaluated during strictly controlled conditions. Levels of nerve growth factor (NGF), calcitonin gene-related peptide (CGRP) and brain derived neurotropic factor (BDNF) were determined using novel western blotting based technology. Glutamate and substance P (SP) was determined using commercial available methods. Several new isoforms were found for NGF, CGRP and BDNF in saliva. The isoform pattern showed significant variation in both expression and chemiluminescence levels between different collection methods. New sensitive methods to study pain related markers in saliva were developed in this study. Furthermore, we are first to demonstrate a correlation between the Glutamate concentration in stimulated whole saliva and blood. However, the fundamental conclusion drawn is the importance of consistency in the collection method.

AB - Mitochondria are cellular organelles with crucial functions in the generation and distribution of ATP, the buffering of cytosolic Ca2+ and the initiation of apoptosis. Compounds that interfere with these functions are termed mitochondrial toxins, many of which are derived from microbes, such as antimycin A, oligomycin A, and ionomycin. Here, we identify the mycotoxin phomoxanthone A (PXA), derived from the endophytic fungus Phomopsis longicolla, as a mitochondrial toxin. We show that PXA elicits a strong release of Ca2+ from the mitochondria but not from the ER. In addition, PXA depolarises the mitochondria similarly to protonophoric uncouplers such as CCCP, yet unlike these, it does not increase but rather inhibits cellular respiration and electron transport chain activity. The respiration-dependent mitochondrial network structure rapidly collapses into fragments upon PXA treatment. Surprisingly, this fragmentation is independent from the canonical mitochondrial fission and fusion mediators DRP1 and OPA1, and exclusively affects the inner mitochondrial membrane, leading to cristae disruption, release of pro-apoptotic proteins, and apoptosis. Taken together, our results suggest that PXA is a mitochondrial toxin with a novel mode of action that might prove a useful tool for the study of mitochondrial ion homoeostasis and membrane dynamics. PMID- 29459716 TI - Common Deregulation of Seven Biological Processes by MicroRNAs in Gastrointestinal Cancers. AB - MicroRNAs are frequently dysregulated in human neoplasms, including gastrointestinal cancers. Nevertheless, the global influence of microRNA dysregulation on cellular signaling is still unknown. Here we sought to elucidate cellular signaling dysregulation by microRNAs in gastrointestinal cancers at the systems biology level followed by experimental validation. Signature dysregulated microRNAs in gastric, colorectal and liver cancers were defined based on our previous studies. Targets of signature dysregulated miRNAs were predicted using multiple computer algorithms followed by gene enrichment analysis to identify biological processes perturbed by dysregulated microRNAs. Effects of microRNAs on endocytosis were measured by epidermal growth factor (EGF) internalization assay. Our analysis revealed that, aside from well-established cancer-related signaling pathways, several novel pathways, including axon guidance, neurotrophin/nerve growth factor signaling, and endocytosis, were found to be involved in the pathogenesis of gastrointestinal cancers. The regulation of EGF receptor (EGFR) endocytosis by two predicted miRNAs, namely miR-17 and miR-145, was confirmed experimentally. Functionally, miR-145, which blocked EGFR endocytosis, prolonged EGFR membrane signaling and altered responsiveness of colon cancer cells to EGFR targeting drugs. In conclusion, our analysis depicts a comprehensive picture of cellular signaling dysregulation, including endocytosis, by microRNAs in gastrointestinal cancers. PMID- 29459717 TI - Silibinin alleviates inflammation and induces apoptosis in human rheumatoid arthritis fibroblast-like synoviocytes and has a therapeutic effect on arthritis in rats. AB - Silibinin, a natural polyphenolic flavonoid, possesses anti-oxidant, anti inflammation and anti-cancer properties. The present study was designed to investigate the effects of silibinin on rheumatoid arthritis (RA) pathogenesis related cells and collagen-induced arthritis (CIA) and further explore the potential underlying mechanisms. Our results showed that silibinin suppressed cell viability and increased the percentage of apoptotic RA-fibroblast-like synoviocytes (FLS). Furthermore, the production of inflammatory cytokines in RA FLS and a CIA rat model was effectively inhibited by silibinin. Silibinin also induced macrophage M2 polarization in RAW264.7 cells. We further demonstrated that silibinin inhibits Th17 cell differentiation in vitro. The nuclear factor kappa B (NF-kappaB) pathway was suppressed in RA-FLS. In addition, Sirtuin1 (SIRT1) was decreased after silibinin treatment, and RA-FLS transfection with a short hairpin RNA (shRNA) of SIRT1 enhanced silibinin-induced apoptosis. Autophagy was markedly decreased in a dose-dependent manner following silibinin treatment. These findings indicate that silibinin inhibited inflammation by inhibiting the NF-kappaB pathway, and SIRT1 may participate in silibinin-induced apoptosis. Silibinin also inhibited autophagy in RA-FLS. Thus, silibinin may be a potential therapeutic agent for the treatment of RA. PMID- 29459718 TI - Systematic generation of biophysically detailed models for diverse cortical neuron types. AB - The cellular components of mammalian neocortical circuits are diverse, and capturing this diversity in computational models is challenging. Here we report an approach for generating biophysically detailed models of 170 individual neurons in the Allen Cell Types Database to link the systematic experimental characterization of cell types to the construction of cortical models. We build models from 3D morphologies and somatic electrophysiological responses measured in the same cells. Densities of active somatic conductances and additional parameters are optimized with a genetic algorithm to match electrophysiological features. We evaluate the models by applying additional stimuli and comparing model responses to experimental data. Applying this technique across a diverse set of neurons from adult mouse primary visual cortex, we verify that models preserve the distinctiveness of intrinsic properties between subsets of cells observed in experiments. The optimized models are accessible online alongside the experimental data. Code for optimization and simulation is also openly distributed. PMID- 29459719 TI - miR-142-3p regulates autophagy by targeting ATG16L1 in thymic-derived regulatory T cell (tTreg). AB - Thymic-derived regulatory T cell (tTreg) clinical trials show therapeutic promise in the prevention of acute graft-versus-host disease (GVHD) in allogeneic hematopoietic stem cell transplantation patients. However, strategies are needed to improve tTreg proliferative ability and survival as a means to improve tTreg therapy and reduce the requirement for producing large numbers of Treg cells for adoptive tTreg transfer. Autophagy is a self-degradative process for cytosolic components, which is involved in cells death, differentiation, lymphocyte homeostasis, and tTreg function. Studies have shown that mice with tTreg cells that have a disrupted autophagy process have defective tTreg cell generation and function, resulting in autoimmune disease and failed GVHD prevention by adoptively transferred tTreg cells. We found the attenuated autophagy status during ex vivo expansion, which leads us to determine whether tTreg cell survival could be augmented by miR-142-3p, the miRNA which is highly expressed in tTreg cells and potentially targets autophagy-related protein (ATG)-1, ATG16L1. We demonstrate that miR-142-3p downregulates ATG16L1 mRNA and production of ATG16L1, that has been linked to autoimmune diseases. Conversely, miR-142-3p knock-down improved tTreg cell expansion, survival and function in vitro and vivo. In aggregate, these studies provide a new approach that uses miR-142-3p knockdown to increase tTreg cell efficacy by increasing ATG16L1 mRNA and protein and the autophagy process. PMID- 29459720 TI - Controlling striatal function via anterior frontal cortex stimulation. AB - Motivational, cognitive and action goals are processed by distinct, topographically organized, corticostriatal circuits. We aimed to test whether processing in the striatum is under causal control by cortical regions in the human brain by investigating the effects of offline transcranial magnetic stimulation (TMS) over distinct frontal regions associated with motivational, cognitive and action goal processing. Using a three-session counterbalanced within-subject crossover design, continuous theta burst stimulation was applied over the anterior prefrontal cortex (aPFC), dorsolateral prefrontal cortex, or premotor cortex, immediately after which participants (N = 27) performed a paradigm assessing reward anticipation (motivation), task (cognitive) switching, and response (action) switching. Using task-related functional magnetic resonance imaging (fMRI), we assessed the effects of stimulation on processing in distinct regions of the striatum. To account for non-specific effects, each session consisted of a baseline (no-TMS) and a stimulation (post-TMS) fMRI run. Stimulation of the aPFC tended to decrease reward-related processing in the caudate nucleus, while stimulation of the other sites was unsuccessful. A follow up analysis revealed that aPFC stimulation also decreased processing in the putamen as a function of the interaction between all factors (reward, cognition and action), suggesting stimulation modulated the transfer of motivational information to cortico-striatal circuitry associated with action control. PMID- 29459721 TI - Debye formulas for a relaxing system with memory. AB - Rate (master) equations are ubiquitous in statistical physics, yet, to the best of our knowledge, a rate equation with memory has previously never been considered. We write down an integro-differential rate equation for the evolution of a thermally relaxing system with memory. For concreteness we adopt as a model a single-domain magnetic particle driven by a small ac field and derive the modified Debye formulas. For any memory time Theta the in-phase component of the resultant ac susceptibility is positive at small probing frequencies omega, but becomes negative at large omega. The system thus exhibits frequency induced diamagnetism. For comparison we also consider particle pairs with dipolar coupling. The memory effect is found to be enhanced by ferromagnetic coupling and suppressed by antiferromagnetic coupling. Numerical calculations support the prediction of a negative susceptibility which arises from a phase shift induced by the memory effect. It is proposed that the onset of frequency induced diamagnetism represents a viable experimental signature of correlated noise. PMID- 29459722 TI - Vesicle-based secretion in schistosomes: Analysis of protein and microRNA (miRNA) content of exosome-like vesicles derived from Schistosoma mansoni. AB - Exosomes are small vesicles of endocytic origin, which are released into the extracellular environment and mediate a variety of physiological and pathological conditions. Here we show that Schistosoma mansoni releases exosome-like vesicles in vitro. Vesicles were purified from culture medium by sucrose gradient fractionation and fractions containing vesicles verified by western blot analyses and electron microscopy. Proteomic analyses of exosomal contents unveiled 130 schistosome proteins. Among these proteins are common exosomal markers such as heat shock proteins, energy-generating enzymes, cytoskeletal proteins, and others. In addition, the schistosome extracellular vesicles contain proteins of potential importance for host-parasite interaction, notably peptidases, signaling proteins, cell adhesion proteins (e.g., integrins) and previously described vaccine candidates, including glutathione-S-transferase (GST), tetraspanin (TSP 2) and calpain. S. mansoni exosomes also contain 143 microRNAs (miRNA), of which 25 are present at high levels, including miRNAs detected in sera of infected hosts. Quantitative PCR analysis confirmed the presence of schistosome-derived miRNAs in exosomes purified from infected mouse sera. The results provide evidence of vesicle-mediated secretion in these parasites and suggest that schistosome-derived exosomes could play important roles in host-parasite interactions and could be a useful tool in the development of vaccines and therapeutics. PMID- 29459723 TI - Generalized leaky integrate-and-fire models classify multiple neuron types. AB - There is a high diversity of neuronal types in the mammalian neocortex. To facilitate construction of system models with multiple cell types, we generate a database of point models associated with the Allen Cell Types Database. We construct a set of generalized leaky integrate-and-fire (GLIF) models of increasing complexity to reproduce the spiking behaviors of 645 recorded neurons from 16 transgenic lines. The more complex models have an increased capacity to predict spiking behavior of hold-out stimuli. We use unsupervised methods to classify cell types, and find that high level GLIF model parameters are able to differentiate transgenic lines comparable to electrophysiological features. The more complex model parameters also have an increased ability to differentiate between transgenic lines. Thus, creating simple models is an effective dimensionality reduction technique that enables the differentiation of cell types from electrophysiological responses without the need for a priori-defined features. This database will provide a set of simplified models of multiple cell types for the community to use in network models. PMID- 29459725 TI - One effector at a time. PMID- 29459724 TI - Assessment of soil heavy metals for eco-environment and human health in a rapidly urbanization area of the upper Yangtze Basin. AB - Soil pollution with heavy metals (HMs) has been attracting more and more interests, however, assessment of eco-environmental and human risks particularly in a rapidly urbanization area (the upper Yangtze) remains limited. Multiple modern indices were firstly performed for complete risk assessment of eco environment and human health based on a high-spatial-resolution sampling. Averages of HMs were far below grade II threshold level of the Chinese Environmental Quality standards for soils, whereas Cd, As and Hg considerably exceeded the local background values. EF suggested overall moderate enrichments of Cd and Se, resulting in soils uncontaminated to moderately contaminated with them. Potential ecological risk index showed significant differences among Counties that were characterized by moderate risk. However, several sites were moderately to heavily contaminated with As, Cd and Hg by Igeo, resulting in that these sites were categorized as "considerable risk", or "high risk". Moreover, children were more susceptible to the potential health risk irrespective of the carcinogenic or non - carcinogenic risk. There were no significant carcinogenic and non - carcinogenic risks for adults, children however showed significant non carcinogenic effect. Our first assessment provided important information for policy making to reduce the potential effects of soil contamination on human and eco-environment. PMID- 29459726 TI - The systemin receptor SYR1 enhances resistance of tomato against herbivorous insects. AB - The discovery in tomato of systemin, the first plant peptide hormone1,2, was a fundamental change for the concept of plant hormones. Numerous other peptides have since been shown to play regulatory roles in many aspects of the plant life, including growth, development, fertilization and interactions with symbiotic organisms3-6. Systemin, an 18 amino acid peptide derived from a larger precursor protein 7 , was proposed to act as the spreading signal that triggers systemic defence responses observed in plants after wounding or attack by herbivores1,7,8. Further work culminated in the identification of a leucine-rich repeat receptor kinase (LRR-RK) as the systemin receptor 160 (SR160)9,10. SR160 is a tomato homologue of Brassinosteroid Insensitive 1 (BRI1), which mediates the regulation of growth and development in response to the steroid hormone brassinolide11-13. However, a role of SR160/BRI1 as systemin receptor could not be corroborated by others14-16. Here, we demonstrate that perception of systemin depends on a pair of distinct LRR-RKs termed SYR1 and SYR2. SYR1 acts as a genuine systemin receptor that binds systemin with high affinity and specificity. Further, we show that presence of SYR1, although not decisive for local and systemic wound responses, is important for defence against insect herbivory. PMID- 29459727 TI - Farming with crops and rocks to address global climate, food and soil security. AB - The magnitude of future climate change could be moderated by immediately reducing the amount of CO2 entering the atmosphere as a result of energy generation and by adopting strategies that actively remove CO2 from it. Biogeochemical improvement of soils by adding crushed, fast-reacting silicate rocks to croplands is one such CO2-removal strategy. This approach has the potential to improve crop production, increase protection from pests and diseases, and restore soil fertility and structure. Managed croplands worldwide are already equipped for frequent rock dust additions to soils, making rapid adoption at scale feasible, and the potential benefits could generate financial incentives for widespread adoption in the agricultural sector. However, there are still obstacles to be surmounted. Audited field-scale assessments of the efficacy of CO2 capture are urgently required together with detailed environmental monitoring. A cost-effective way to meet the rock requirements for CO2 removal must be found, possibly involving the recycling of silicate waste materials. Finally, issues of public perception, trust and acceptance must also be addressed. PMID- 29459728 TI - Silencing SlMED18, tomato Mediator subunit 18 gene, restricts internode elongation and leaf expansion. AB - Mediator complex, a conserved multi-protein, is necessary for controlling RNA polymerase II (Pol II) transcription in eukaryotes. Given little is known about them in tomato, a tomato Mediator subunit 18 gene was isolated and named SlMED18. To further explore the function of SlMED18, the transgenic tomato plants targeting SlMED18 by RNAi-mediated gene silencing were generated. The SlMED18 RNAi lines exhibited multiple developmental defects, including smaller size and slower growth rate of plant and significantly smaller compound leaves. The contents of endogenous bioactive GA3 in SlMED18 silenced lines were slightly less than that in wild type. Furthermore, qRT-PCR analysis indicated that expression of gibberellins biosynthesis genes such as SlGACPS and SlGA20x2, auxin transport genes (PIN1, PIN4, LAX1 and LAX2) and several key regulators, KNOX1, KNOX2, PHAN and LANCEOLATE(LA), which involved in the leaf morphogenesis were significantly down-regulated in SlMED18-RNAi lines. These results illustrated that SlMED18 plays an essential role in regulating plant internode elongation and leaf expansion in tomato plants and it acts as a key positive regulator of gibberellins biosynthesis and signal transduction as well as auxin proper transport signalling. These findings are the basis for understanding the function of the individual Mediator subunits in tomato. PMID- 29459729 TI - New Zealand glowworm (Arachnocampa luminosa) bioluminescence is produced by a firefly-like luciferase but an entirely new luciferin. AB - The New Zealand glowworm, Arachnocampa luminosa, is well-known for displays of blue-green bioluminescence, but details of its bioluminescent chemistry have been elusive. The glowworm is evolutionarily distant from other bioluminescent creatures studied in detail, including the firefly. We have isolated and characterised the molecular components of the glowworm luciferase-luciferin system using chromatography, mass spectrometry and 1H NMR spectroscopy. The purified luciferase enzyme is in the same protein family as firefly luciferase (31% sequence identity). However, the luciferin substrate of this enzyme is produced from xanthurenic acid and tyrosine, and is entirely different to that of the firefly and known luciferins of other glowing creatures. A candidate luciferin structure is proposed, which needs to be confirmed by chemical synthesis and bioluminescence assays. These findings show that luciferases can evolve independently from the same family of enzymes to produce light using structurally different luciferins. PMID- 29459730 TI - A single NaK channel conformation is not enough for non-selective ion conduction. AB - NaK and other non-selective channels are able to conduct both sodium (Na+) and potassium (K+) with equally high efficiency. In contrast to previous crystallographic results, we show that the selectivity filter (SF) of NaK in native-like lipid membranes adopts two distinct conformations that are stabilized by either Na+ or K+ ions. The atomic differences of these conformations are resolved by solid-state NMR (ssNMR) spectroscopy and molecular dynamics (MD) simulations. Besides the canonical K+ permeation pathway, we identify a side entry ion-conduction pathway for Na+ permeation unique to NaK. Moreover, under otherwise identical conditions ssNMR spectra of the K+ selective NaK mutant (NaK2K) reveal only a single conformational state. Therefore, we propose that structural plasticity within the SF and the selection of these conformations by different ions are key molecular determinants for highly efficient conduction of different ions in non-selective cation channels. PMID- 29459731 TI - Involvement of impaired autophagy and mitophagy in Neuro-2a cell damage under hypoxic and/or high-glucose conditions. AB - Chronic cerebral hypoperfusion (CCH) plays an insidious role in the development of cognitive impairment. Considerable evidence suggests that Diabetes Mellitus (DM) as a vascular risk factor may exacerbate CCH and is closely related to cognitive decline. Dysregulation of autophagy is known to be associated with the pathogenesis of neurodegenerative diseases such as Alzheimer's disease. To elucidate the role of autophagy in CCH- and/or DM-related pathogenesis, mouse neuroblastoma Neuro-2a cells were exposed to hypoxia and/or high glucose for 48 h, mimicking CCH complicated with DM pathologies. Chronic hypoxia reduced cell proliferation and increased levels of cleaved caspase-3, whereas high glucose had no obvious synergistic toxic effect. Accumulation of autophagic vacuoles under hypoxia may be due to both autophagy impairment and induction, with the former accounting for Neuro-2a cell death. Additionally, aberrant accumulation of mitochondria in Neuro-2a cells may be attributed to insufficient BNIP3-mediated mitophagy due to poor interaction between BNIP3 and LC3-II. Despite the lack of a significant cytotoxic effect of high glucose under our experimental conditions, our data indicated for the first time that impaired autophagy degradation and inefficient BNIP3-mediated mitophagy may constitute mechanisms underlying neuronal cell damage during chronic hypoxia. PMID- 29459732 TI - A protease cascade regulates release of the human malaria parasite Plasmodium falciparum from host red blood cells. AB - Malaria parasites replicate within a parasitophorous vacuole in red blood cells (RBCs). Progeny merozoites egress upon rupture of first the parasitophorous vacuole membrane (PVM), then poration and rupture of the RBC membrane (RBCM). Egress is protease-dependent 1 , but none of the effector molecules that mediate membrane rupture have been identified and it is unknown how sequential rupture of the two membranes is controlled. Minutes before egress, the parasite serine protease SUB1 is discharged into the parasitophorous vacuole2-6 where it cleaves multiple substrates2,5,7-9 including SERA6, a putative cysteine protease10-12. Here, we show that Plasmodium falciparum parasites lacking SUB1 undergo none of the morphological transformations that precede egress and fail to rupture the PVM. In contrast, PVM rupture and RBCM poration occur normally in SERA6-null parasites but RBCM rupture does not occur. Complementation studies show that SERA6 is an enzyme that requires processing by SUB1 to function. RBCM rupture is associated with SERA6-dependent proteolytic cleavage within the actin-binding domain of the major RBC cytoskeletal protein beta-spectrin. We conclude that SUB1 and SERA6 play distinct, essential roles in a coordinated proteolytic cascade that enables sequential rupture of the two bounding membranes and culminates in RBCM disruption through rapid, precise, SERA6-mediated disassembly of the RBC cytoskeleton. PMID- 29459733 TI - Conditional toxicity and synergy drive diversity among antibacterial effectors. AB - Bacteria in polymicrobial habitats contend with a persistent barrage of competitors, often under rapidly changing environmental conditions 1 . The direct antagonism of competitor cells is thus an important bacterial survival strategy 2 . Towards this end, many bacterial species employ an arsenal of antimicrobial effectors with multiple activities; however, the benefits conferred by the simultaneous deployment of diverse toxins are unknown. Here we show that the multiple effectors delivered to competitor bacteria by the type VI secretion system (T6SS) of Pseudomonas aeruginosa display conditional efficacy and act synergistically. One of these effectors, Tse4, is most active in high-salinity environments and synergizes with effectors that degrade the cell wall or inactivate intracellular electron carriers. We find Tse4 synergizes with these disparate mechanisms by forming pores that disrupt the DeltaPsi component of the proton motive force. Our results provide evidence that the concomitant delivery of a cocktail of effectors serves as a bet-hedging strategy to promote bacterial competitiveness in the face of unpredictable and variable environmental conditions. PMID- 29459734 TI - The CaV2alpha1 EF-hand F helix tyrosine, a highly conserved locus for GPCR inhibition of CaV2 channels. AB - The sensory neuron of Aplysia californica participates in several forms of presynaptic plasticity including homosynaptic depression, heterosynaptic depression, facilitation and the reversal of depression. The calcium channel triggering neurotransmitter release at most synapses is CaV2, consisting of the pore forming alpha1 subunit (CaV2alpha1), and auxiliary CaVbeta, and CaValpha2delta subunits. To determine the role of the CaV2 channel in presynaptic plasticity in Aplysia, we cloned Aplysia CaV2alpha1, CaVbeta, and CaValpha2delta and over-expressed the proteins in Aplysia sensory neurons (SN). We show expression of exogenous CaV2alpha1 in the neurites of cultured Aplysia SN. One proposed mechanism for heterosynaptic depression in Aplysia is through inhibition of CaV2. Here, we demonstrate that heterosynaptic depression of the CaV2 calcium current is inhibited when a channel with a Y-F mutation at the conserved Src phosphorylation site is expressed, showing the strong conservation of this mechanism over evolution. We also show that the Y-F mutation reduces heterosynaptic inhibition of neurotransmitter release, highlighting the physiological importance of this mechanism for the regulation of synaptic efficacy. These results also demonstrate our ability to replace endogenous CaV2 channels with recombinant channels allowing future examination of the structure function relationship of CaV2 in the regulation of transmitter release in this system. PMID- 29459735 TI - Structural heterogeneity of the rat pulmonary vein myocardium: consequences on intracellular calcium dynamics and arrhythmogenic potential. AB - Mechanisms underlying ectopic activity in the pulmonary vein (PV) which triggers paroxysmal atrial fibrillation are unknown. Although several studies have suggested that calcium signalling might be involved in these arrhythmias, little is known about calcium cycling in PV cardiomyocytes (CM). We found that individual PV CM showed a wide range of transverse tubular incidence and organization, going from their virtual absence, as described in atrial CM, to well transversally organised tubular systems, like in ventricular CM. These different types of CM were found in groups scattered throughout the tissue. The variability of the tubular system was associated with cell to cell heterogeneity of calcium channel (Cav1.2) localisation and, thereby, of Cav1.2-Ryanodine receptor coupling. This was responsible for multiple forms of PV CM calcium transient. Spontaneous calcium sparks and waves were not only more abundant in PV CM than in LA CM but also associated with a higher depolarising current. In conclusion, compared with either the atrium or the ventricle, PV myocardium presents marked structural and functional heterogeneity. PMID- 29459736 TI - Photonic-crystal exciton-polaritons in monolayer semiconductors. AB - Semiconductor microcavity polaritons, formed via strong exciton-photon coupling, provide a quantum many-body system on a chip, featuring rich physics phenomena for better photonic technology. However, conventional polariton cavities are bulky, difficult to integrate, and inflexible for mode control, especially for room-temperature materials. Here we demonstrate sub-wavelength-thick, one dimensional photonic crystals as a designable, compact, and practical platform for strong coupling with atomically thin van der Waals crystals. Polariton dispersions and mode anti-crossings are measured up to room temperature. Non radiative decay to dark excitons is suppressed due to polariton enhancement of the radiative decay. Unusual features, including highly anisotropic dispersions and adjustable Fano resonances in reflectance, may facilitate high temperature polariton condensation in variable dimensions. Combining slab photonic crystals and van der Waals crystals in the strong coupling regime allows unprecedented engineering flexibility for exploring novel polariton phenomena and device concepts. PMID- 29459737 TI - Elevated intracellular cAMP exacerbates vulnerability to oxidative stress in optic nerve head astrocytes. AB - Glaucoma is characterized by a progressive loss of retinal ganglion cells and their axons, but the underlying biological basis for the accompanying neurodegeneration is not known. Accumulating evidence indicates that structural and functional abnormalities of astrocytes within the optic nerve head (ONH) have a role. However, whether the activation of cyclic adenosine 3',5'-monophosphate (cAMP) signaling pathway is associated with astrocyte dysfunction in the ONH remains unknown. We report here that the cAMP/protein kinase A (PKA) pathway is critical to ONH astrocyte dysfunction, leading to caspase-3 activation and cell death via the AKT/Bim/Bax signaling pathway. Furthermore, elevated intracellular cAMP exacerbates vulnerability to oxidative stress in ONH astrocytes, and this may contribute to axonal damage in glaucomatous neurodegeneration. Inhibition of intracellular cAMP/PKA signaling activation protects ONH astrocytes by increasing AKT phosphorylation against oxidative stress. These results strongly indicate that activation of cAMP/PKA pathway has an important role in astrocyte dysfunction, and suggest that modulating cAMP/PKA pathway has therapeutic potential for glaucomatous ONH degeneration. PMID- 29459738 TI - Epistasis between FLG and IL4R Genes on the Risk of Allergic Sensitization: Results from Two Population-Based Birth Cohort Studies. AB - Immune-specific genes as well as genes responsible for the formation and integrity of the epidermal barrier have been implicated in the pathogeneses of allergic sensitization. This study sought to determine whether an epistatic effect (gene-gene interaction) between genetic variants within interleukin 4 receptor (IL4R) and filaggrin (FLG) genes predispose to the development of allergic sensitization. Data from two birth cohort studies were analyzed, namely the Isle of Wight (IOW; n = 1,456) and the Manchester Asthma and Allergy Study (MAAS; n = 1,058). In the IOW study, one interaction term (IL4R rs3024676 * FLG variants) showed statistical significance (interaction term: P = 0.003). To illustrate the observed epistasis, stratified analyses were performed, which showed that FLG variants were associated with allergic sensitization only among IL4R rs3024676 homozygotes (OR, 1.97; 95% CI, 1.27-3.05; P = 0.003). In contrast, FLG variants effect was masked among IL4R rs3024676 heterozygotes (OR, 0.53; 95% CI, 0.22-1.32; P = 0.175). Similar results were demonstrated in the MAAS study. Epistasis between immune (IL4R) and skin (FLG) regulatory genes exist in the pathogenesis of allergic sensitization. Hence, genetic susceptibility towards defective epidermal barrier and deviated immune responses could work together in the development of allergic sensitization.

PMID- 29459739 TI - Localization of adaptive variants in human genomes using averaged one-dependence estimation. AB - Statistical methods for identifying adaptive mutations from population genetic data face several obstacles: assessing the significance of genomic outliers, integrating correlated measures of selection into one analytic framework, and distinguishing adaptive variants from hitchhiking neutral variants. Here, we introduce SWIF(r), a probabilistic method that detects selective sweeps by learning the distributions of multiple selection statistics under different evolutionary scenarios and calculating the posterior probability of a sweep at each genomic site. SWIF(r) is trained using simulations from a user-specified demographic model and explicitly models the joint distributions of selection statistics, thereby increasing its power to both identify regions undergoing sweeps and localize adaptive mutations. Using array and exome data from 45 ?Khomani San hunter-gatherers of southern Africa, we identify an enrichment of adaptive signals in genes associated with metabolism and obesity. SWIF(r) provides a transparent probabilistic framework for localizing beneficial mutations that is extensible to a variety of evolutionary scenarios. PMID- 29459741 TI - A fuzzy feature fusion method for auto-segmentation of gliomas with multi modality diffusion and perfusion magnetic resonance images in radiotherapy. AB - The diffusion and perfusion magnetic resonance (MR) images can provide functional information about tumour and enable more sensitive detection of the tumour extent. We aimed to develop a fuzzy feature fusion method for auto-segmentation of gliomas in radiotherapy planning using multi-parametric functional MR images including apparent diffusion coefficient (ADC), fractional anisotropy (FA) and relative cerebral blood volume (rCBV). For each functional modality, one histogram-based fuzzy model was created to transform image volume into a fuzzy feature space. Based on the fuzzy fusion result of the three fuzzy feature spaces, regions with high possibility belonging to tumour were generated automatically. The auto-segmentations of tumour in structural MR images were added in final auto-segmented gross tumour volume (GTV). For evaluation, one radiation oncologist delineated GTVs for nine patients with all modalities. Comparisons between manually delineated and auto-segmented GTVs showed that, the mean volume difference was 8.69% (+/-5.62%); the mean Dice's similarity coefficient (DSC) was 0.88 (+/-0.02); the mean sensitivity and specificity of auto-segmentation was 0.87 (+/-0.04) and 0.98 (+/-0.01) respectively. High accuracy and efficiency can be achieved with the new method, which shows potential of utilizing functional multi-parametric MR images for target definition in precision radiation treatment planning for patients with gliomas. PMID- 29459742 TI - Impact of aromatase absence on murine intraocular pressure and retinal ganglion cells. AB - We hypothesize that aromatase, an enzyme that regulates estrogen production, plays a significant role in the control of intraocular pressure (IOP) and retinal ganglion cells (RGCs). To begin to test our hypothesis, we examined the impact of aromatase absence, which completely eliminates estrogen synthesis, in male and female mice. Studies were performed with adult, age-matched wild type (WT) and aromatase knockout (ArKO) mice. IOP was measured in a masked fashion in both eyes of conscious mice at 12 and 24 weeks of age. Retinas were obtained and processed for RGC counting with a confocal microscope. IOP levels in both 12- and 24-week old female ArKO mice were significantly higher than those of age- and sex-matched WT controls. The mean increase in IOP was 7.9% in the 12-week-, and 19.7% in the 24-week-old mice, respectively. These changes were accompanied by significant 9% and 7% decreases in RGC numbers in the ArKO female mice, relative to controls, at 12- and 24-weeks, respectively. In contrast, aromatase deficiency did not lead to an increased IOP in male mice. There was a significant reduction in RGC counts in the 12-, but not 24-, week-old male ArKO mice, as compared to their age- and sex matched WT controls. Overall, our findings show that aromatase inhibition in females is associated with elevated IOP and reduced RGC counts. PMID- 29459743 TI - Gray and white matter integrity influence TMS signal propagation: a multimodal evaluation in cocaine-dependent individuals. AB - Transcranial magnetic stimulation (TMS) can stimulate cortical and subcortical brain regions. However, in order to reach subcortical targets, intact monosynaptic connections are required. The goal of this investigation was to evaluate the contribution of white matter integrity and gray matter volume to frontal pole TMS-evoked striatal activity in a large cohort of chronic cocaine users. 49 cocaine users received single pulses of TMS to the frontal pole while BOLD data were acquired - a technique known as interleaved TMS/fMRI. Diffusion tensor imaging and voxel-based morphometry were used to quantify white matter integrity and gray matter volume (GMV), respectively. Stepwise regression was used to evaluate the contribution of clinical and demographic variables to TMS evoked BOLD. Consistent with previous studies, frontal pole TMS evoked activity in striatum and salience circuitry. The size of the TMS-evoked response was related to fractional anisotropy between the frontal pole and putamen and GMV in the left frontal pole and left ACC. This is the first study to demonstrate that the effect of TMS on subcortical activity is dependent upon the structural integrity of the brain. These data suggest that these structural neuroimaging data types are biomarkers for TMS-induced mobilization of the striatum.

AB - Endometriosis (ENDO) is a common gynecological disease that causes infertility in many women. Previous studies noted that the dysregulation of Homeo box A10 (HOXA10) in the endometrium of women with ENDO was involved in the failure of embryo implantation. However, the mechanism by which HOXA10 expression is reduced in women with ENDO is still poorly understood. Here we found that a member of the calcium (Ca2+)-dependent cysteine protease family calpain7 (CAPN7), negatively correlated with HOXA10, was highly expressed in the endometrium of infertile women with ENDO and was significantly downregulated during the window of embryo implantation in mice. Overexpression of CAPN7 in Ishikawa cells or in the uterus of mice inhibited embryo implantation in vitro and in vivo. In the current study, we identified a sequence rich in proline, glutamic acid, serine, and threonine (PEST sequence) that enhanced the Ca2+-dependent degradation of HOXA10 by CAPN7. Furthermore, the interaction between HOXA10 and CAPN7 repressed the transcriptional activity and protein stability of HOXA10. In contrast, the administration of the calpain inhibitor ALLN reversed the CAPN7-induced HOXA10 degradation. Moreover, truncation of the PEST motif in HOXA10 abolished its CAPN7 dependent proteolysis. These studies reveal a novel pattern of HOXA10 regulation via PEST sequence-mediated calpain proteolysis that was demonstrated to be reversed by a calpain inhibitor. Thus, the inhibition of CAPN7-induced HOXA10 degradation may represent a novel potential therapeutic method to improve impaired embryo implantation in women with ENDO.

AB - Central blood pressure level is not always consistent with peripheral blood pressure level, and especially their joint effect on incident hypertension is not well established. A total of 1607 non-hypertensive subjects from an atherosclerosis cohort in Beijing, China were included. Central systolic blood pressure (cSBP) was obtained using Omron HEM-9000AI machine and peripheral systolic blood pressure (pSBP) was measured using Omron HEM-7117 electronic sphygmomanometer, separately. Hypertension was defined as BP >= 140/90 mmHg or self-reported hypertension or taking any antihypertension drugs at the follow-up survey. After a median follow-up of 2.3 years, incident hypertension was 13.1%. Every 1 standard deviation increase of cSBP and pSBP was associated with 1.98 (95%CI: 1.69-2.33) and 2.84 (95%CI: 2.30-3.52) times of incident hypertension after adjustment for confounders. Moreover, hypertension risk in single pSBP >= 120 mmHg group, single cSBP >= 120 mmHg group, and both pSBP and cSBP >= 120 mmHg group was 2.83 (95%CI: 0.98-8.16), 3.28 (95%CI: 1.24-8.70), and 11.47 (95%CI: 4.97-26.46) times higher than both pSBP and cSBP < 120 mmHg group, respectively. The joint effect of cSBP and pSBP is superior to either cSBP or pSBP to predict incident hypertension in a Chinese community-based population. Screening of central blood pressure should be considered in non-hypertensive population for the purpose of primary intervention, especially for subjects with pSBP >= 120 mmHg. PMID- 29459746 TI - Simultaneous Strength-Ductility Enhancement of a Nano-Lamellar AlCoCrFeNi2.1 Eutectic High Entropy Alloy by Cryo-Rolling and Annealing. AB - Nano-lamellar (L12 + B2) AlCoCrFeNi2.1 eutectic high entropy alloy (EHEA) was processed by cryo-rolling and annealing. The EHEA developed a novel hierarchical microstructure featured by fine lamellar regions consisting of FCC lamellae filled with ultrafine FCC grains (average size ~200-250 nm) and B2 lamellae, and coarse non-lamellar regions consisting of ultrafine FCC (average size ~200-250 nm), few coarse recrystallized FCC grains and rather coarse unrecrystallized B2 phase (~2.5 um). This complex and hierarchical microstructure originated from differences in strain-partitioning amongst the constituent phases, affecting the driving force for recrystallization. The hierarchical microstructure of the cryo rolled and annealed material resulted in simultaneous enhancement in strength (Yield Strength/YS: 1437 +/- 26 MPa, Ultimate Tensile Strength/UTS: 1562 +/- 33 MPa) and ductility (elongation to failure/ef ~ 14 +/- 1%) as compared to the as cast as well as cold-rolled and annealed materials. The present study for the first time demonstrated that cryo-deformation and annealing could be a novel microstructural design strategy for overcoming strength-ductility trade off in multiphase high entropy alloys. PMID- 29459747 TI - Universal strategy for Ohmic hole injection into organic semiconductors with high ionization energies. AB - Barrier-free (Ohmic) contacts are a key requirement for efficient organic optoelectronic devices, such as organic light-emitting diodes, solar cells, and field-effect transistors. Here, we propose a simple and robust way of forming an Ohmic hole contact on organic semiconductors with a high ionization energy (IE). The injected hole current from high-work-function metal-oxide electrodes is improved by more than an order of magnitude by using an interlayer for which the sole requirement is that it has a higher IE than the organic semiconductor. Insertion of the interlayer results in electrostatic decoupling of the electrode from the semiconductor and realignment of the Fermi level with the IE of the organic semiconductor. The Ohmic-contact formation is illustrated for a number of material combinations and solves the problem of hole injection into organic semiconductors with a high IE of up to 6 eV. PMID- 29459748 TI - Genesis, challenges and opportunities for colloidal lead halide perovskite nanocrystals. AB - Lead halide perovskites (LHPs) in the form of nanometre-sized colloidal crystals, or nanocrystals (NCs), have attracted the attention of diverse materials scientists due to their unique optical versatility, high photoluminescence quantum yields and facile synthesis. LHP NCs have a 'soft' and predominantly ionic lattice, and their optical and electronic properties are highly tolerant to structural defects and surface states. Therefore, they cannot be approached with the same experimental mindset and theoretical framework as conventional semiconductor NCs. In this Review, we discuss LHP NCs historical and current research pursuits, challenges in applications, and the related present and future mitigation strategies explored. PMID- 29459749 TI - Human Pressures on Natural Reserves in Yunnan Province and Management Implications. AB - The analysis of status and major sources of human pressures on natural reserves (NRs) is important for optimizing their management. This study selected population density, gross domestic product (GDP) density and areal percentage of human land use to reveal the human pressures of national and provincial NRs (NNRs and PNRs) in Yunnan Province, China. We calculated three types of internal and external human pressure index (HPI) and comprehensive HPI (CHPI) for NRs. Human pressures on most of NRs were slight and light, indicating that most of NRs were well protected. Human pressures on PNRs were higher than on NNRs; with respect to five types of NRs, geological relict NRs were facing the highest human pressures, followed by wetland ecosystem NRs. Land use and population density were the main human pressures on these NRs. Yunnan Province should put the highest emphasis on three NNRs and two Ramsar site PNRs with severe CHPI, secondly pay attention to eight conservation-oriented PNRs with extreme or severe CHPI. It's urgent for Yunnan to implement scientific policies and measures to reduce land use and population density pressures of NRs, especially with severe and extreme CHPI, by transforming internal land use and/or implementing residents' eco-migration. PMID- 29459750 TI - Climate variability in the northern and southern Altai Mountains during the past 50 years. AB - The Holocene drying trend in the northern Altai Mountains and the wetting trend in the southern Altai Mountains inferred from the paleoclimatic studies indicated it is needed to understand the modern climatic characters in this region. However, a detailed analysis of modern climate variations in the northern and southern Altai Mountains is lacking. Here, we investigate the monthly temperature and monthly precipitation data from seventeen meteorological stations during 1966 2015 in the northern and southern Altai. The result shows that temperature increases significantly in the northern (0.42 degrees C/10 yr) and in the southern (0.54 degrees C/10 yr). The precipitation decreases insignificantly ( 1.41 mm/10 yr) in the northern, whereas it increases significantly (8.89 mm/10 yr) in the southern. The out-of-phase relationship of precipitation changes is also recorded at different time-scales (i.e., season, year, multi-decades, centennial and millennial scales), indicating the Altai Mountains are an important climatic boundary. Based on the analysis of modern atmosphere circulation, the decreased precipitation in the northern corresponds to the decreasing contribution of 'Northern meridional and Stationary anticyclone' and 'Northern meridional and East zonal' circulation and the increased precipitation in the southern are associated with the increasing contribution of 'West zonal and Southern meridional' circulation. PMID- 29459751 TI - Relevance of electrical current distribution to the forced flow and grain refinement in solidified Al-Si hypoeutectic alloy. AB - Significant grain refinement in cast metals can be achieved through the application of electric currents during the solidification process. The present paper investigates the distribution of electric currents on the grain size of solidified Al-7wt.%Si alloy under the application of electric current with constant parameters flowing through two parallel electrodes into the melt within a cylindrical mould. The distribution of electric current was controlled by applying an electrical insulation material coating, boron nitride (NB), to the sidewall of the electrodes. Experimental results showed that the employment of these insulated electrodes can reduce grain size in comparison with the reference case of electrodes without BN coating. Flow measurements were performed in Ga 20wt.%In-12wt.%Sn liquid metal. Higher intensity forced flow occurred when the sidewall of the electrodes was insulated. In order to understand the underlying mechanism behind the stronger forced flow, corresponding numerical simulations were performed to reveal the distributions of the electric current, magnetic field, Lorentz force, and the resultant forced flow. The results achieved indicate that the mechanism of grain refinement driven by electric current is dendrite fragmentation induced by forced flow. In addition, a novel approach to enhance the grain refinement without additional input of current energy was developed. PMID- 29459753 TI - Cooling aerosols and changes in albedo counteract warming from CO2 and black carbon from forest bioenergy in Norway. AB - Climate impacts of forest bioenergy result from a multitude of warming and cooling effects and vary by location and technology. While past bioenergy studies have analysed a limited number of climate-altering pollutants and activities, no studies have jointly addressed supply chain greenhouse gas emissions, biogenic CO2 fluxes, aerosols and albedo changes at high spatial and process detail. Here, we present a national-level climate impact analysis of stationary bioenergy systems in Norway based on wood-burning stoves and wood biomass-based district heating. We find that cooling aerosols and albedo offset 60-70% of total warming, leaving a net warming of 340 or 69 kg CO2e MWh-1 for stoves or district heating, respectively. Large variations are observed over locations for albedo, and over technology alternatives for aerosols. By demonstrating both notable magnitudes and complexities of different climate warming and cooling effects of forest bioenergy in Norway, our study emphasizes the need to consider multiple forcing agents in climate impact analysis of forest bioenergy. PMID- 29459756 TI - Humility. AB - This paper offers a nuanced discourse on the otherwise ignored topic of humility. It brings together scattered comments within psychoanalysis, secular lay literature, sociocultural studies, and religious thought on humility. The paper also describes pathological variants of humility (excessive, deficient, false, and compartmentalized) and delineates five areas of clinical practice where humility plays an important role: (i) humility in selecting patients to treat, (ii) humility in daily conduct with patients, (iii) humility in the attitude of listening to clinical material, (iv) humility in the manner of intervening, and (v) humility in deciding upon the longevity of our professional careers. PMID- 29459754 TI - Cocaine-induced locomotor sensitization associates with slow oscillatory firing of neurons in the ventral tegmental area. AB - The initiation of psychostimulant sensitization depends on the mesocorticolimbic dopamine (DA) system. Although many cellular adaptations has been reported to be associated with this addictive behavior, the overall influence of these adaptations on the network regulation of DA neurons has not been established. Here, we profile a network-driven slow oscillation (SO) in the firing activity of ventral tegmental area (VTA) putative DA and non-DA neurons and their correlation with locomotor sensitization induced by repeated administration of cocaine. One day after the last cocaine injection, the power of SO (Pso) significantly increased both in DA and non-DA neurons. Interestingly, the Pso in DA neurons was positively correlated, while Pso in non-DA neurons was negatively correlated with the level of locomotor sensitization. On the other hand, the firing rates of DA and non-DA neurons were both elevated, but none exhibited any correlation with the level of sensitization. Fourteen days after the last injection, the Pso of DA neurons dissipated but still positively correlated with the level of sensitization. In contrast, the Pso in non-DA neurons lost correlation with locomotor sensitization. These results suggest that cocaine-induced locomotor sensitization is associated with long-term network adaptation in DA system and that DA and non-DA neurons may corporately facilitate/hamper the initiation of locomotor sensitization. PMID- 29459752 TI - Characterization of viral RNA splicing using whole-transcriptome datasets from host species. AB - RNA alternative splicing (AS) is an important post-transcriptional mechanism enabling single genes to produce multiple proteins. It has been well demonstrated that viruses deploy host AS machinery for viral protein productions. However, knowledge on viral AS is limited to a few disease-causing viruses in model species. Here we report a novel approach to characterizing viral AS using whole transcriptome dataset from host species. Two insect transcriptomes (Acheta domesticus and Planococcus citri) generated in the 1,000 Insect Transcriptome Evolution (1KITE) project were used as a proof of concept using the new pipeline. Two closely related densoviruses (Acheta domesticus densovirus, AdDNV, and Planococcus citri densovirus, PcDNV, Ambidensovirus, Densovirinae, Parvoviridae) were detected and analyzed for AS patterns. The results suggested that although the two viruses shared major AS features, dramatic AS divergences were observed. Detailed analysis of the splicing junctions showed clusters of AS events occurred in two regions of the virus genome, demonstrating that transcriptome analysis could gain valuable insights into viral splicing. When applied to large-scale transcriptomics projects with diverse taxonomic sampling, our new method is expected to rapidly expand our knowledge on RNA splicing mechanisms for a wide range of viruses. PMID- 29459758 TI - Ultrafast evolution of electric fields from high-intensity laser-matter interactions. AB - The interaction of high-power ultra-short lasers with materials offers fascinating wealth of transient phenomena which are in the core of novel scientific research. Deciphering its evolution is a complicated task that strongly depends on the details of the early phase of the interaction, which acts as complex initial conditions. The entire process, moreover, is difficult to probe since it develops close to target on the sub-picosecond timescale and ends after some picoseconds. Here we present experimental results related to the fields and charges generated by the interaction of an ultra-short high-intensity laser with metallic targets. The temporal evolution of the interaction is probed with a novel femtosecond resolution diagnostics that enables the differentiation of the contribution by the high-energy forerunner electrons and the radiated electromagnetic pulses generated by the currents of the remaining charges on the target surface. Our results provide a snapshot of huge pulses, up to 0.6 teravolt per meter, emitted with multi-megaelectronvolt electron bunches with sub picosecond duration and are able to explore the processes involved in laser matter interactions at the femtosecond timescale. PMID- 29459759 TI - Genomics of a pediatric ovarian fibrosarcoma. Association with the DICER1 syndrome. AB - Ovarian fibrosarcomas are extremely rare tumors with little genomic information available to date. In the present report we present the tumoral exome and transcriptome and the germinal exome of an ovarian fibrosarcoma from a 9-years old child. We found a paucity of mutations (0.77/Mb) and CNV alterations. Of these, the most relevant were a point mutation in the metal-binding site of the microRNA-processing DICER1 enzyme and a frame-shift alteration in the tumor suppressor gene NF1. We validated a germinal truncating mutation in DICER1, which was consistent with a DICER1 Syndrome diagnosis, providing the first example of an ovarian fibrosarcoma as the presenting neoplasia in this syndrome. Network and enrichment analyses showed that both a mesenchymal signature and a Hedgehog cascade could be driving the progression of this tumor. We were also able to find a global lincRNA deregulation, as the number of lincRNAs transcripts expressed in the tumor was decreased, with a concomitant upregulation of previously described non-coding transcripts associated with cancer, such as MALAT1, MIR181A1HG, CASC1, XIST and FENDRR. DICER1 Syndrome should be considered as a possible diagnosis in children ovarian fibrosarcoma. The role of lncRNAs in neoplasias associated with DICER1 alterations need to be studied in more detail. PMID- 29459760 TI - Light pollution is greatest within migration passage areas for nocturnally migrating birds around the world. AB - Excessive or misdirected artificial light at night (ALAN) produces light pollution that influences several aspects of the biology and ecology of birds, including disruption of circadian rhythms and disorientation during flight. Many migrating birds traverse large expanses of land twice every year at night when ALAN illuminates the sky. Considering the extensive and increasing encroachment of light pollution around the world, we evaluated the association of the annual mean ALAN intensity over land within the geographic ranges of 298 nocturnally migrating bird species with five factors: phase of annual cycle, mean distance between breeding and non-breeding ranges, range size, global hemisphere of range, and IUCN category of conservation concern. Light pollution within geographic ranges was relatively greater during the migration season, for shorter-distance migrants, for species with smaller ranges, and for species in the western hemisphere. Our results suggest that migratory birds may be subject to the effects of light pollution particularly during migration, the most critical stage in their annual cycle. We hope these results will spur further research on how light pollution affects not only migrating birds, but also other highly mobile animals throughout their annual cycle. PMID- 29459761 TI - Matched case-control study of the influence of inland waters surrounding poultry farms on avian influenza outbreaks in Japan. AB - To successfully control highly pathogenic avian influenza (HPAI), understanding the risk factors related to the incursion of the virus into poultry farms is essential. In this study, we focused on the presence of inland waters surrounding poultry farms as a potential risk factor of incursion of the virus. To evaluate the influence of inland waters surrounding poultry farms on HPAI outbreaks in Japan, a simple matched case-control study was conducted. The results of the conditional regression analyses indicated that the number of farms with neighbouring inland waters was significantly high among the affected farms during the 2016-2017 outbreak period. These results provide good grounds for strengthening biosecurity management at farms located near inland waters. PMID- 29459762 TI - The characteristics of positive and confusing hand X-ray signs in diagnosing Kashin-Beck Disease in children in China. AB - When screening for Kashin-Beck disease (KBD) in children, hand X-ray examination is the most important measure. However, there is high rate of misdiagnosis because of confusing X-ray signs. We studied the characteristics of positive and confusing hand X-ray signs. Clinical and radiological examinations were conducted in all 7- to 12-year-olds in selected villages from some KBD and non-KBD areas. We analysed the radiological and epidemiological characteristics of the X-ray signs of KBD and the confusing signs. Images from 3,193 children were valid. No cases of KBD were found. Seventeen children (0.53%) had X-ray signs positive for KBD. The confusing X-ray signs included closure reaction of metaphysis-epiphysis (CRME, 14.28%), thumb variation (0.22%), little finger variation (8.89%), the second metacarpal-phalangeal variation (0.13%) and cystic change (3.85%). The onset of CRME in children occurred earlier in girls (9) than in boys (10). The onset occurred earlier in KBD areas (9) than in non-KBD areas (10). The onset occurred earlier in Han children (9) than in Tibetan children (11). In summary, KBD was effectively controlled in all investigated KBD endemic villages, and the age range should be adjusted to 7- to 11-year-olds in Han children to reduce the misdiagnosis rates in KBD surveillance. PMID- 29459763 TI - Single excitatory axons form clustered synapses onto CA1 pyramidal cell dendrites. AB - CA1 pyramidal neurons are a major output of the hippocampus and encode features of experience that constitute episodic memories. Feature-selective firing of these neurons results from the dendritic integration of inputs from multiple brain regions. While it is known that synchronous activation of spatially clustered inputs can contribute to firing through the generation of dendritic spikes, there is no established mechanism for spatiotemporal synaptic clustering. Here we show that single presynaptic axons form multiple, spatially clustered inputs onto the distal, but not proximal, dendrites of CA1 pyramidal neurons. These compound connections exhibit ultrastructural features indicative of strong synapses and occur much more commonly in entorhinal than in thalamic afferents. Computational simulations revealed that compound connections depolarize dendrites in a biophysically efficient manner, owing to their inherent spatiotemporal clustering. Our results suggest that distinct afferent projections use different connectivity motifs that differentially contribute to dendritic integration. PMID- 29459764 TI - Shared neural coding for social hierarchy and reward value in primate amygdala. AB - The social brain hypothesis posits that dedicated neural systems process social information. In support of this, neurophysiological data have shown that some brain regions are specialized for representing faces. It remains unknown, however, whether distinct anatomical substrates also represent more complex social variables, such as the hierarchical rank of individuals within a social group. Here we show that the primate amygdala encodes the hierarchical rank of individuals in the same neuronal ensembles that encode the rewards associated with nonsocial stimuli. By contrast, orbitofrontal and anterior cingulate cortices lack strong representations of hierarchical rank while still representing reward values. These results challenge the conventional view that dedicated neural systems process social information. Instead, information about hierarchical rank-which contributes to the assessment of the social value of individuals within a group-is linked in the amygdala to representations of rewards associated with nonsocial stimuli. PMID- 29459765 TI - Filling the Gaps in the Kirromycin Biosynthesis: Deciphering the Role of Genes Involved in Ethylmalonyl-CoA Supply and Tailoring Reactions. AB - Kirromycin is the main product of the soil-dwelling Streptomyces collinus Tu 365. The elucidation of the biosynthetic pathway revealed that the antibiotic is synthesised via a unique combination of trans-/cis-AT type I polyketide synthases and non-ribosomal peptide synthetases (PKS I/NRPS). This was the first example of an assembly line integrating the three biosynthetic principles in one pathway. However, information about other enzymes involved in kirromycin biosynthesis remained scarce. In this study, genes encoding tailoring enzymes KirM, KirHVI, KirOI, and KirOII, and the putative crotonyl-CoA reductase/carboxylase KirN were deleted, complemented, and the emerged products analysed by HPLC-HRMS and MS/MS. Derivatives were identified in mutants DeltakirM, DeltakirHVI, DeltakirOI, and DeltakirOII. The products of DeltakirOI, DeltakirOII, and kirHVI were subjected to 2D-NMR for structure elucidation. Our results enabled functional assignment of those enzymes, demonstrating their involvement in kirromycin tailoring. In the DeltakirN mutant, the production of kirromycin was significantly decreased. The obtained data enabled us to clarify the putative roles of the studied enzymes, ultimately allowing us to fill many of the missing gaps in the biosynthesis of the complex antibiotic. Furthermore, this collection of mutants can serve as a toolbox for generation of new kirromycins. PMID- 29459766 TI - Greater corneal nerve loss at the inferior whorl is related to the presence of diabetic neuropathy and painful diabetic neuropathy. AB - We assessed whether a measure of more distal corneal nerve fibre loss at the inferior whorl(IW) region is better than proximal measures of central corneal nerve damage in relation to the diagnosis of diabetic peripheral neuropathy(DPN), painful DPN and quality of life(QoL). Participants underwent detailed assessment of neuropathy, QoL using the SF36 questionnaire, pain visual analogue score(VAS), and corneal confocal microscopy(CCM). Corneal nerve fibre density (CNFD), branch density (CNBD) and length (CNFL) at the central cornea and inferior whorl length (IWL) and average(ANFL) and total(TNFL) nerve fibre length were compared in patients with and without DPN and between patients with and without painful DPN and in relation to QoL. All CCM parameters were significantly reduced, but IWL was reduced ~three-fold greater than CNFL in patients with and without DPN compared to controls. IWL(p = 0.001), ANFL(p = 0.01) and TNFL(p = 0.02) were significantly lower in patients with painful compared to painless DPN. The VAS score correlated with IWL(r = -0.36, P = 0.004), ANFL(r = -0.32, P = 0.01) and TNFL(r = -0.32, P = 0.01) and QoL correlated with CNFL(r = 0.35, P = 0.01) and IWL(r = 0.4, P = 0.004). Corneal nerve fibre damage is more prominent at the IW, lower in patients with painful compared to painless neuropathy and relates to their QoL. IWL may provide additional clinical utility for CCM in patients with DPN. PMID- 29459767 TI - Mcl-1 and Bcl-xL sequestration of Bak confers differential resistance to BH3-only proteins. AB - The prosurvival Bcl-2 family proteins Mcl-1 and Bcl-xL inhibit apoptosis by sequestering BH3-only proteins such as Bid and Bim (MODE 1) or the effector proteins Bak and Bax (MODE 2). To better understand the contributions of MODE 1 and MODE 2 in blocking cell death, and thus how to bypass resistance to cell death, we examined prescribed mixtures of Bcl-2 family proteins. In a Bim and Bak mixture, Bcl-xL and Mcl-1 each sequestered not only Bim but also Bak as it became activated by Bim. In contrast, in a Bid and Bak mixture, Bcl-xL preferentially sequestered Bid while Mcl-1 preferentially sequestered Bak. Notably, Bcl-xL could sequester Bak in response to the BH3 mimetic ABT-737, despite this molecule targeting Bcl-xL. These findings highlight the importance of Bak sequestration in resistance to anti-cancer treatments, including BH3 mimetics. PMID- 29459768 TI - Oncoprotein Tudor-SN is a key determinant providing survival advantage under DNA damaging stress. AB - Herein, Tudor-SN was identified as a DNA damage response (DDR)-related protein that plays important roles in the early stage of DDR. X-ray or laser irradiation could evoke the accumulation of Tudor-SN to DNA damage sites in a poly(ADP ribosyl)ation-dependent manner via interaction with PARP-1. Additionally, we illustrated that the SN domain of Tudor-SN mediated the association of these two proteins. The accumulated Tudor-SN further recruited SMARCA5 (ATP-dependent chromatin remodeller) and GCN5 (histone acetyltransferase) to DNA damage sites, resulting in chromatin relaxation, and consequently activating the ATM kinase and downstream DNA repair signalling pathways to promote cell survival. Consistently, the loss-of-function of Tudor-SN attenuated the enrichment of SMARCA5, GCN5 and acetylation of histone H3 (acH3) at DNA break sites and abolished chromatin relaxation; as a result, the cells exhibited DNA repair and cell survival deficiency. As Tudor-SN protein is highly expressed in different tumours, it is likely to be involved in the radioresistance of cancer treatment. PMID- 29459770 TI - Polycomb protein family member CBX7 regulates intrinsic axon growth and regeneration. AB - Neurons in the central nervous system (CNS) lose their intrinsic ability and fail to regenerate, but the underlying mechanisms are largely unknown. Polycomb group (PcG) proteins, which include PRC1 and PRC2 complexes function as gene repressors and are involved in many biological processes. Here we report that PRC1 components (polycomb chromobox (CBX) 2, 7, and 8) are novel regulators of axon growth and regeneration. Especially, knockdown of CBX7 in either embryonic cortical neurons or adult dorsal root ganglion (DRG) neurons enhances their axon growth ability. Two important transcription factors GATA4 and SOX11 are functional downstream targets of CBX7 in controlling axon regeneration. Moreover, knockdown of GATA4 or SOX11 in cultured DRG neurons inhibits axon regeneration response from CBX7 downregulation in DRG neurons. These findings suggest that targeting CBX signaling pathway may be a novel approach for promoting the intrinsic regenerative capacity of damaged CNS neurons. PMID- 29459769 TI - Exploring the genetics and non-cell autonomous mechanisms underlying ALS/FTLD. AB - Although amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, was first described in 1874, a flurry of genetic discoveries in the last 10 years has markedly increased our understanding of this disease. These findings have not only enhanced our knowledge of mechanisms leading to ALS, but also have revealed that ALS shares many genetic causes with another neurodegenerative disease, frontotemporal lobar dementia (FTLD). In this review, we survey how recent genetic studies have bridged our mechanistic understanding of these two related diseases and how the genetics behind ALS and FTLD point to complex disorders, implicating non-neuronal cell types in disease pathophysiology. The involvement of non-neuronal cell types is consistent with a non-cell autonomous component in these diseases. This is further supported by studies that identified a critical role of immune-associated genes within ALS/FTLD and other neurodegenerative disorders. The molecular functions of these genes support an emerging concept that various non-autonomous functions are involved in neurodegeneration. Further insights into such a mechanism(s) will ultimately lead to a better understanding of potential routes of therapeutic intervention. Facts ALS and FTLD are severe neurodegenerative disorders on the same disease spectrum. Multiple cellular processes including dysregulation of RNA homeostasis, imbalance of proteostasis, contribute to ALS/FTLD pathogenesis. Aberrant function in non-neuronal cell types, including microglia, contributes to ALS/FTLD. Strong neuroimmune and neuroinflammatory components are associated with ALS/FTLD patients. Open Questions Why can patients with similar mutations have different disease manifestations, i.e., why do C9ORF72 mutations lead to motor neuron loss in some patients while others exhibit loss of neurons in the frontotemporal lobe? Do ALS causal mutations result in microglial dysfunction and contribute to ALS/FTLD pathology? How do microglia normally act to mitigate neurodegeneration in ALS/FTLD? To what extent do cellular signaling pathways mediate non-cell autonomous communications between distinct central nervous system (CNS) cell types during disease? Is it possible to therapeutically target specific cell types in the CNS?

AB - The regeneration of intestinal epithelial are maintained by continuous differentiation and proliferation of intestinal stem cells (ISCs) under physiological and pathological conditions. However, little is known about the regulatory effect of intestinal microbiota on its recovery ability to repair damaged mucosal barrier. In this study, we established intestinal organoids and lamina propria lymphocytes (LPLs) co-cultured system, plus mice experiments, to explore the protective effect of Lactobacillus reuteri D8 on integrity of intestinal mucosa. We found that only live L. reuteri D8 was effective in protecting the morphology of intestinal organoids and normal proliferation of epithelial stained with EdU under TNF-alpha treatment, which was also further verified in mice experiments. L. reuteri D8 colonized in the intestinal mucosa and ameliorated intestinal mucosa damage caused by DSS treatment, including improvement of body weight, colon length, pathological change, and proliferation level. The repair process stimulated by L. reuteri D8 was also accompanied with increased numbers of Lgr5+ and lysozyme+ cells both in intestinal organoids and mice intestine. Furthermore, we demonstrated that D8 metabolite indole-3-aldehyde stimulated LPLs to secret IL-22 through aryl hydrocarbon receptor (AhR) and then induced phosphorylation of STAT3 to accelerate proliferation of intestinal epithelial, thus recovering damaged intestinal mucosa. Our findings indicate L. reuteri protects intestinal barrier and activates intestinal epithelial proliferation, which sheds light on treatment approaches for intestinal inflammation based on ISCs with probiotics Lactobacillus and daily probiotic consumption in heath foods.

AB - Monoamine oxidase (MAO) inhibitors ameliorate contractile function in diabetic animals, but the mechanisms remain unknown. Equally elusive is the interplay between the cardiomyocyte alterations induced by hyperglycemia and the accompanying inflammation. Here we show that exposure of primary cardiomyocytes to high glucose and pro-inflammatory stimuli leads to MAO-dependent increase in reactive oxygen species that causes permeability transition pore opening and mitochondrial dysfunction. These events occur upstream of endoplasmic reticulum (ER) stress and are abolished by the MAO inhibitor pargyline, highlighting the role of these flavoenzymes in the ER/mitochondria cross-talk. In vivo, streptozotocin administration to mice induced oxidative changes and ER stress in the heart, events that were abolished by pargyline. Moreover, MAO inhibition prevented both mast cell degranulation and altered collagen deposition, thereby normalizing diastolic function. Taken together, these results elucidate the mechanisms underlying MAO-induced damage in diabetic cardiomyopathy and provide novel evidence for the role of MAOs in inflammation and inter-organelle communication. MAO inhibitors may be considered as a therapeutic option for diabetic complications as well as for other disorders in which mast cell degranulation is a dominant phenomenon. PMID- 29459773 TI - Erythrocyte glutathione transferase in kidney transplantation: a probe for kidney detoxification efficiency. AB - Erythrocyte glutathione transferase (e-GST) is overexpressed in case of increased blood toxicity and its level correlates with the kidney disease progression. Thus, it represents a probe of kidney efficiency against circulating toxins. We measured the activity of e-GST in patients with transplant kidney from living and cadaver donors, correlated its level to biochemical parameters of kidney function, and measured the level of oxidized albumin as a probe of oxidative stress using a new simple procedure. Interestingly, the activity of e-GST in transplant patients from cadaver donors (N = 153) is very high (11.7 U/gHb) compared to healthy subjects (N = 80) ( 5.6 U/gHb). Lower values were observed in transplant patients with kidney from living donors (N = 16) (9.8 U/gHb). Except for steroids, no correlation has been found with the immunosuppressive therapies and routine clinical and laboratory parameters. Also serum oxidized albumin, which reveals oxidative stress, is significantly higher in transplant patients from cadaver donors (53%) compared to that from living donors (36%). Overall, these data indicate that most of transplant kidneys from cadavers lost part of the detoxifying power against circulating toxins and suffer a relevant oxidative stress compared to those coming from living donors. A case report suggests that e GST could represent a very early marker of incipient graft rejection. In conclusion, e-GST may be used to check the decline or maintenance of the kidney detoxification competence during post-transplantation course. PMID- 29459774 TI - Nonylphenol aggravates non-alcoholic fatty liver disease in high sucrose-high fat diet-treated rats. AB - Exposure to environmental endocrine disruptors (EEDs) contributes to the pathogenesis of many metabolic disorders. Here, we have analyzed the effect of the EED-nonylphenol (NP) on the promotion of non-alcoholic fatty liver disease (NAFLD) in rats fed high sucrose-high fat diet (HSHFD). Fifty Sprague-Dawley rats were divided into five groups: controls fed a normal diet (C-ND); HSHFD-fed controls (C-HSHFD); and rats fed a HSHFD combined with NP at doses of 0.02 MUg/kg/day (NP-L-HSHFD), 0.2 MUg/kg/day (NP-M-HSHFD), and 2 MUg/kg/day (NP-H HSHFD). Subchronic exposure to NP coupled with HSHFD increased daily water and food intake (p < 0.05), hepatic echogenicity and oblique liver diameter (p < 0.05), and plasma levels of alanine aminotransferase, aspartate aminotransferase, total cholesterol, triglycerides, and low density lipoprotein cholesterol (p < 0.05). Combined exposure to NP and HSHFD induced macrovesicular steatosis with dilation and congestion of the central vein, liver inflammatory cell infiltration, and expression of genes regulating lipid metabolism, SREBP-1C, FAS, and Ucp2. These results demonstrate that NP aggravates NAFLD in HSHFD-treated rats by up-regulating lipogenic genes, and that HSHFD increases the toxic effects of NP. Thus subchronic NP exposure may lead to NAFLD, especially when combined with a high-sucrose/high-fat diet. PMID- 29459776 TI - Antibodies in children with malaria to PfEMP1, RIFIN and SURFIN expressed at the Plasmodium falciparum parasitized red blood cell surface. AB - Naturally acquired antibodies to proteins expressed on the Plasmodium falciparum parasitized red blood cell (pRBC) surface steer the course of a malaria infection by reducing sequestration and stimulating phagocytosis of pRBC. Here we have studied a selection of proteins representing three different parasite gene families employing a well-characterized parasite with a severe malaria phenotype (FCR3S1.2). The presence of naturally acquired antibodies, impact on rosetting rate, surface reactivity and opsonization for phagocytosis in relation to different blood groups of the ABO system were assessed in a set of sera from children with mild or complicated malaria from an endemic area. We show that the naturally acquired immune responses, developed during malaria natural infection, have limited access to the pRBCs inside a blood group A rosette. The data also indicate that SURFIN4.2 may have a function at the pRBC surface, particularly during rosette formation, this role however needs to be further validated. Our results also indicate epitopes differentially recognized by rosette-disrupting antibodies on a peptide array. Antibodies towards parasite-derived proteins such as PfEMP1, RIFIN and SURFIN in combination with host factors, essentially the ABO blood group of a malaria patient, are suggested to determine the outcome of a malaria infection. PMID- 29459778 TI - Effects of dipolar interactions on the sensitivity of nonlinear spinor-BEC interterometry. AB - We consider the effects of dipole-dipole interactions on a nonlinear interferometer with spin-1 Bose-Einstein condensates. Compared with the traditional atomic SU(1,1) interferometer, the shot-noise phase sensitivity can be beaten with respect to the input total average number of particles; and the improved sensitivity depends on the effective strength of the dipolar interaction via modifying the trapping geometry. It indicates that the best performance of the interferometer is achieved with highly oblate trap potential. The Bayesian phase estimation strategy is explored to extract the phase information. We show that the Cramer-Rao phase uncertainly bound can saturate, when the ideal dis entangle scheme is applied. The phase average of the phase sensitivity is also discussed. PMID- 29459777 TI - Ceramic Microbial Fuel Cells Stack: power generation in standard and supercapacitive mode. AB - In this work, a microbial fuel cell (MFC) stack containing 28 ceramic MFCs was tested in both standard and supercapacitive modes. The MFCs consisted of carbon veil anodes wrapped around the ceramic separator and air-breathing cathodes based on activated carbon catalyst pressed on a stainless steel mesh. The anodes and cathodes were connected in parallel. The electrolytes utilized had different solution conductivities ranging from 2.0 mScm-1 to 40.1 mScm-1, simulating diverse wastewaters. Polarization curves of MFCs showed a general enhancement in performance with the increase of the electrolyte solution conductivity. The maximum stationary power density was 3.2 mW (3.2 Wm-3) at 2.0 mScm-1 that increased to 10.6 mW (10.6 Wm-3) at the highest solution conductivity (40.1 mScm 1). For the first time, MFCs stack with 1 L operating volume was also tested in supercapacitive mode, where full galvanostatic discharges are presented. Also in the latter case, performance once again improved with the increase in solution conductivity. Particularly, the increase in solution conductivity decreased dramatically the ohmic resistance and therefore the time for complete discharge was elongated, with a resultant increase in power. Maximum power achieved varied between 7.6 mW (7.6 Wm-3) at 2.0 mScm-1 and 27.4 mW (27.4 Wm-3) at 40.1 mScm-1. PMID- 29459775 TI - Formalising recall by genotype as an efficient approach to detailed phenotyping and causal inference. AB - Detailed phenotyping is required to deepen our understanding of the biological mechanisms behind genetic associations. In addition, the impact of potentially modifiable risk factors on disease requires analytical frameworks that allow causal inference. Here, we discuss the characteristics of Recall-by-Genotype (RbG) as a study design aimed at addressing both these needs. We describe two broad scenarios for the application of RbG: studies using single variants and those using multiple variants. We consider the efficacy and practicality of the RbG approach, provide a catalogue of UK-based resources for such studies and present an online RbG study planner. PMID- 29459779 TI - Small molecule metabolite biomarkers for hepatocellular carcinoma with bile duct tumor thrombus diagnosis. AB - Hepatocellular carcinoma with bile duct tumor thrombus (BDTT) is a malignant disease. The most commonly used diagnosis methods for BDTT are MRCP/ERCP, ultrasonic diagnosis or CT scan. However, BDTT is often misdiagnosed as other bile duct diseases, such as extrahepatic cholangiocarcinoma (EHCC), choledochal cyst (Cyst) and common bile duct stone (Stone). Diagnostic methods, which are more accurate and less destructive, are urgently needed. In this paper, we analyzed the small molecule metabolites in the serum of BDTT, Stone, Cyst and EHCC patients and normal people using untargeted GC-MS, and identified 21 metabolites that show different levels among different samples. Using targeted UHPLC-QQQ-MS analysis, we found that several metabolites are significantly changed. ROC curve analysis revealed two metabolites, L-citrulline and D-aspartic acid, as potential biomarkers that can distinguish BDTT from other bile duct diseases. PMID- 29459781 TI - RIPK1-mediated induction of mitophagy compromises the viability of extracellular matrix-detached cells. AB - For cancer cells to survive during extracellular matrix (ECM) detachment, they must inhibit anoikis and rectify metabolic deficiencies that cause non-apoptotic cell death. Previous studies in ECM-detached cells have linked non-apoptotic cell death to reactive oxygen species (ROS) generation, although the mechanistic underpinnings of this link remain poorly defined. Here, we uncover a role for receptor-interacting protein kinase 1 (RIPK1) in the modulation of ROS and cell viability during ECM detachment. We find that RIPK1 activation during ECM detachment results in mitophagy induction through a mechanism dependent on the mitochondrial phosphatase PGAM5. As a consequence of mitophagy, ECM-detached cells experience diminished NADPH production in the mitochondria, and the subsequent elevation in ROS levels leads to non-apoptotic death. Furthermore, we find that antagonizing RIPK1/PGAM5 enhances tumour formation in vivo. Thus, RIPK1 mediated induction of mitophagy may be an efficacious target for therapeutics aimed at eliminating ECM-detached cancer cells. PMID- 29459782 TI - Distinct macular thickness changes after femtosecond laser-assisted cataract surgery of age-related cataract and myopia with cataract. AB - Cataract surgery can cause macular thickness change. We used optical coherence tomography (OCT) to assess the macular thickness of different regions after femtosecond laser-assisted cataract surgery of age-related cataracts (ARC) and myopia cases with cataract (myopia group). Fifty eyes of 50 patients in ARC group and fifty eyes of 50 patients in myopia with cataract group were included. All study underwent femtosecond laser-assisted cataract surgery and macular thickness of was measured at pre-operation and 1 week, 1 month after surgery. There are significant differences of foveal thickness (P = 0.02), foveal volume (P = 0.02) and average retinal thickness (P = 0.02) between two groups before operation. In the myopia group, statistically significant differences were not found in postoperative macular thickness as compared with ARC group. There are differences in macular thickness between pre-operation and 1 month after operation when compared with nasal outer macular ring thickness (P = 0.022), foveal volume (P = 0.005) and average retinal thickness (P = 0.012) in ARC group. The study suggest that femtosecond laser-assisted cataract extraction is safe in myopia group that did not cause significant increase of macular thickness. However, an increased post-operative local macular thickness was recoded while comparing macular thickness with the baseline in ARC group. PMID- 29459783 TI - Nanodiamonds for device applications: An investigation of the properties of boron doped detonation nanodiamonds. AB - The inclusion of boron within nanodiamonds to create semiconducting properties would create a new class of applications in the field of nanodiamond electronics. Theoretical studies have differed in their conclusions as to whether nm-scale NDs would support a stable substitutional boron state, or whether such a state would be unstable, with boron instead aggregating or attaching to edge structures. In the present study detonation-derived NDs with purposefully added boron during the detonation process have been studied with a wide range of experimental techniques. The DNDs are of ~4 nm in size, and have been studied with CL, PL, Raman and IR spectroscopies, AFM and HR-TEM and electrically measured with impedance spectroscopy; it is apparent that the B-DNDs studied here do indeed support substitutional boron species and hence will be acting as semiconducting diamond nanoparticles. Evidence for moderate doping levels in some particles (~1017 B cm-3), is found alongside the observation that some particles are heavily doped (~1020 B cm-3) and likely to be quasi-metallic in character. The current study has therefore shown that substitutional boron doping in nm NDs is in fact possible, opening-up the path to a whole host of new applications for this interesting class of nano-particles. PMID- 29459780 TI - Identification of distinct nanoparticles and subsets of extracellular vesicles by asymmetric flow field-flow fractionation. AB - The heterogeneity of exosomal populations has hindered our understanding of their biogenesis, molecular composition, biodistribution and functions. By employing asymmetric flow field-flow fractionation (AF4), we identified two exosome subpopulations (large exosome vesicles, Exo-L, 90-120 nm; small exosome vesicles, Exo-S, 60-80 nm) and discovered an abundant population of non-membranous nanoparticles termed 'exomeres' (~35 nm). Exomere proteomic profiling revealed an enrichment in metabolic enzymes and hypoxia, microtubule and coagulation proteins as well as specific pathways, such as glycolysis and mTOR signalling. Exo-S and Exo-L contained proteins involved in endosomal function and secretion pathways, and mitotic spindle and IL-2/STAT5 signalling pathways, respectively. Exo-S, Exo L and exomeres each had unique N-glycosylation, protein, lipid, DNA and RNA profiles and biophysical properties. These three nanoparticle subsets demonstrated diverse organ biodistribution patterns, suggesting distinct biological functions. This study demonstrates that AF4 can serve as an improved analytical tool for isolating extracellular vesicles and addressing the complexities of heterogeneous nanoparticle subpopulations. PMID- 29459784 TI - 2'-O-methylation in mRNA disrupts tRNA decoding during translation elongation. AB - Chemical modifications of mRNA may regulate many aspects of mRNA processing and protein synthesis. Recently, 2'-O-methylation of nucleotides was identified as a frequent modification in translated regions of human mRNA, showing enrichment in codons for certain amino acids. Here, using single-molecule, bulk kinetics and structural methods, we show that 2'-O-methylation within coding regions of mRNA disrupts key steps in codon reading during cognate tRNA selection. Our results suggest that 2'-O-methylation sterically perturbs interactions of ribosomal monitoring bases (G530, A1492 and A1493) with cognate codon-anticodon helices, thereby inhibiting downstream GTP hydrolysis by elongation factor Tu (EF-Tu) and A-site tRNA accommodation, leading to excessive rejection of cognate aminoacylated tRNAs in initial selection and proofreading. Our current and prior findings highlight how chemical modifications of mRNA tune the dynamics of protein synthesis at different steps of translation elongation. PMID- 29459785 TI - GlcNAc-1-P-transferase-tunicamycin complex structure reveals basis for inhibition of N-glycosylation. AB - N-linked glycosylation is a predominant post-translational modification of protein in eukaryotes, and its dysregulation is the etiology of several human disorders. The enzyme UDP-N-acetylglucosamine:dolichyl-phosphate N acetylglucosaminephosphotransferase (GlcNAc-1-P-transferase or GPT) catalyzes the first and committed step of N-linked glycosylation in the endoplasmic reticulum membrane, and it is the target of the natural product tunicamycin. Tunicamycin has potent antibacterial activity, inhibiting the bacterial cell wall synthesis enzyme MraY, but its usefulness as an antibiotic is limited by off-target inhibition of human GPT. Our understanding of how tunicamycin inhibits N-linked glycosylation and efforts to selectively target MraY are hampered by a lack of structural information. Here we present crystal structures of human GPT in complex with tunicamycin. Structural and functional analyses reveal the difference between GPT and MraY in their mechanisms of inhibition by tunicamycin. We demonstrate that this difference could be exploited to design MraY-specific inhibitors as potential antibiotics. PMID- 29459786 TI - Are 'fruits and vegetables' intake really what they seem in India? AB - BACKGROUND/OBJECTIVES: Fruits and vegetables are integral parts of a healthy diet. This study evaluated the quantity and diversity of the fruit and vegetable intake in India, with a focus on its distribution across sectors and wealth quintiles. SUBJECTS/METHODS: A secondary data analysis on the nation-wide NSSO Household Consumer Expenditure Survey 2011-2012 was performed to estimate the amount (g/capita/day) and diversity of household intake of fruits and vegetables in the rural and the urban sectors of India. Using the expenditure data, households in both the sectors were further divided into wealth quintiles and differences in the diversity of intake was evaluated across these quintiles separately for each sector. RESULTS: The per capita household vegetable and fruit intake was found to be 145 and 15 g, respectively, for rural India, and 155 and 29 g for urban India. A significant portion of this intake came from energy-dense food items; potatoes and bananas for vegetable and fruit intake respectively. Further, while wealth marginally improved the diversity in vegetable intake, no such trend was observed in fruit intake. CONCLUSIONS: Given the high proportion of energy-dense fruits and vegetables in the Indian total intake, the focus should be on improving the diversity of vegetables, as well as on increasing the intake and diversity of fruits. PMID- 29459787 TI - Nutritional risk screening score is an independent predictive factor of anastomotic leakage after rectal cancer surgery. AB - BACKGROUND/OBJECTIVES: Nutritional risk screening (NRS) score has been reported as a predictor of postoperative outcomes in patients undergoing abdominal surgery, although the correlation between NRS and anastomotic leakage (AL) after rectal cancer surgery is uncertain. This study aimed to evaluate the association between NRS score and AL following rectal cancer surgery. SUBJECT/METHODS: We retrospectively reviewed data of rectal cancer patients from a tertiary referral center in South Korea, and included 1063 patients with primary rectal cancer who underwent sphincter-preserving surgery between January 2011 and December 2015. We utilized the Chonnam National University Hwasun Hospital-Nutritional Risk Screening Tool (CNUHH-NRST), which was developed and cross-validated on the basis of the NRS 2002 and MST, as a screening tool of nutritional risk. Patients with NRS scores >=4 were compared with those with NRS scores <4, and the risk factors for AL were analyzed. RESULTS: One-hundred-nineteen (11.2%) patients had high nutritional risk (NRS score >=4). The patients with a nutritional risk had more advanced tumor stages than those without nutritional risk. AL occurred in 69 (6.5%) patients. The multivariate logistic regression analysis showed high American Society of Anesthesiologists score (odds ratio (OR) = 2.435, 95% confidence interval (CI) = 1.085-5.469), long operative time (OR = 1.975, 95% CI = 1.177-3.313), and high NRS score (OR = 2.044, 95% CI = 1.085-3.851) as independent risk factors of AL. CONCLUSIONS: The NRS score was an independent predictive factor of AL after rectal cancer surgery. Patients with nutritional risks who require rectal cancer surgery should be carefully managed. PMID- 29459788 TI - Balloon-assisted ultrasonic localization: a novel technique for direct percutaneous endoscopic jejunostomy. AB - Direct percutaneous endoscopic jejunostomy (DPEJ) is a useful method for the establishment of enteral nutrition (EN) pathway. However, the identification of stomal puncture points for DPEJ is difficult. Here we present a case treated with an improved technique for DPEJ puncture-point localization, which was named DPEJ with balloon-assisted ultrasonic localization (DPEJ-BAUL). There were four steps after insertion of an endoscope into the jejunum: (1) a balloon dilatation catheter was inserted through the endoscope working channel; (2) the balloon was fully filled with water; (3) the site of puncture was selected with an ultrasonic probe percutaneously locating the water-filled balloon; and (4) a jejunostomy tube was placed by introducer technique. Rapid localization of a puncture site was possible with BAUL and the DPEJ procedure was successful. The patient's nutritional status was improved with EN and no postoperative complications were observed. DPEJ-BAUL is a feasible and effective technique to increase the technical success rate of DPEJ in patients with negative transillumination test results. PMID- 29459789 TI - Retrospective observational cohort study regarding the effect of breastfeeding on challenge-proven food allergy. AB - BACKGROUND/OBJECTIVES: Human breast milk is generally regarded as the best nutrition for infants in their first months of life. Whether breastfeeding has a protective effect on food allergy is a point of debate and the subject of this study. SUBJECTS/METHODS: This retrospective study was conducted in 649 children who underwent a double-blind placebo-controlled food challenge (DBPCFC) as part of routine care in a tertiary care clinic. Food allergy was defined as having at least one positive DBPCFC to any food. The association between both "any" breastfeeding (yes/no) and its duration in months with food allergy was studied by logistic regression analysis with correction for confounding variables. RESULTS: The prevalence of food allergy was 58.9% (n = 382). Of all subjects, 75.8% (n = 492) was breastfed and 24.2% (n = 157) bottle-fed. There was no significant association between food allergy and breastfeeding versus bottle feeding after correction for the confounding effect of increased breastfeeding by atopic parents and a history of asthma in the child (OR = 1.24, 95% CI = 0.85 1.79, p = 0.27). However, in breastfed children, every additional month of breastfeeding lowered the risk for food allergy by ~4% (OR = 0.96, 95% CI = 0.93 0.99, p = 0.02). No confounders were identified in this association. CONCLUSION: These results show for the first time that in children investigated for possible food allergy, every additional month of breastfeeding is associated with a lower risk of developing clinical food allergy as diagnosed by DBPCFC. However, overall, there was no association between the prevalence of food allergy and breastfeeding versus bottle-feeding in this tertiary care population. PMID- 29459790 TI - The simplified nutrient profiling system (SENS) adequately ranks foods in relation to the overall nutritional quality of diets: a validation study. AB - BACKGROUND/OBJECTIVES: We aimed to validate the simplified nutrient profiling system (SENS) algorithm based on its ability to rank foods across the four SENS classes in relation to overall nutritional quality of both observed diets and nutritionally optimized diets. SUBJECTS/METHODS: Foods and beverages from the French nutritional composition database were classified according to SENS. Diets consumed by French adults in the latest national dietary survey (>19 years, n = 1719) were divided into four nutritional quality levels, and average daily frequencies (number of portions per day) of foods from the four SENS classes were compared between the four levels. Then, for each individual observed diet, one iso-caloric and nutritionally adequate diet was optimized, and variations in daily frequencies of foods from each SENS class between observed and optimized diets were estimated. RESULTS: In observed diets, as overall nutritional quality level of diet increased, daily frequency increased for Class-1 foods (3.5 to 8.7 portions/d) and decreased for Class-4 foods (6.8 to 3.0 portions/day). From observed to optimized diets, daily frequency increased for Class-1 foods for 98.4% of individuals and decreased for Class-4 foods for 94.2% of individuals. Class-2 and Class-3 foods also followed patterns that fit the expected ranking. CONCLUSIONS: Results from two WHO-recommended validation approaches showed that the SENS algorithm adequately ranks foods according to their contribution to overall nutritional quality of diets, which is a pre-requisite to use for simplified nutritional labeling in Europe. PMID- 29459791 TI - Different enteral nutrition formulas have no effect on glucose homeostasis but on diet-induced thermogenesis in critically ill medical patients: a randomized controlled trial. AB - BACKGROUND/OBJECTIVES: Hyperglycemia is common in critically ill patients and associated with increased mortality. It has been suggested that different nutrition formulas may beneficially influence glucose levels in surgical intensive care patients. In this prospective randomized clinical cohort study we investigated glucose homeostasis in response to different enteral nutrition formulas in medical critically ill patients. SUBJECTS/METHODS: 60 medical critically ill patients were randomized to receive continuous fat-based (group A, n = 30) or glucose-based enteral nutrition (group B, n = 30) for seven days. Indirect calorimetry was performed to determine energy demand at baseline and on days 3 and 7. Glucose levels and area under the curve (AUC), insulin demand, glucose variability, and calorie and substrate intake per 24 h were assessed for 7 days. RESULTS: Over the course of 7 days patients had similar average daily glucose (p = 0.655), glucose AUC (A: 758 (641-829) mg/dl/day vs B: 780 (733-845) mg/dl/day, p = 0.283), similar overall insulin demand (A: 153.5 (45.3-281.5) IE vs B: 167.9 (82.3-283.8) IE, p = 0.525), and received similar amounts of enteral nutrition per 24 h. Resting energy expenditure was similar at baseline (A: 1556 (1227-1808) kcal/day vs B: 1563 (1306-1789) kcal/day, p = 0.882) but energy expenditure increased substantially over time in group A (p < 0.0001), but not in group B (p = 0.097). CONCLUSION: Fat-based and glucose-based EN influence glucose homeostasis and insulin demand similarly, yet diet-induced thermogenesis was substantially higher in critically ill patients receiving fat-based enteral nutrition. PMID- 29459793 TI - Consequences of SPAK inactivation on Hyperkalemic Hypertension caused by WNK1 mutations: evidence for differential roles of WNK1 and WNK4. AB - Mutations of the gene encoding WNK1 [With No lysine (K) kinase 1] or WNK4 cause Familial Hyperkalemic Hypertension (FHHt). Previous studies have shown that the activation of SPAK (Ste20-related Proline/Alanine-rich Kinase) plays a dominant role in the development of FHHt caused by WNK4 mutations. The implication of SPAK in FHHt caused by WNK1 mutation has never been investigated. To clarify this issue, we crossed WNK1+/FHHt mice with SPAK knock-in mice in which the T-loop Thr243 residue was mutated to alanine to prevent activation by WNK kinases. We show that WNK1+/FHHT:SPAK 243A/243A mice display an intermediate phenotype, between that of control and SPAK 243A/243A mice, with normal blood pressure but hypochloremic metabolic alkalosis. NCC abundance and phosphorylation levels also decrease below the wild-type level in the double-mutant mice but remain higher than in SPAK 243A/243A mice. This is different from what was observed in WNK4 FHHt mice in which SPAK inactivation completely restored the phenotype and NCC expression to wild-type levels. Although these results confirm that FHHt caused by WNK1 mutations is dependent on the activation of SPAK, they suggest that WNK1 and WNK4 play different roles in the distal nephron. PMID- 29459792 TI - C-terminal calcium binding of alpha-synuclein modulates synaptic vesicle interaction. AB - Alpha-synuclein is known to bind to small unilamellar vesicles (SUVs) via its N terminus, which forms an amphipathic alpha-helix upon membrane interaction. Here we show that calcium binds to the C terminus of alpha-synuclein, therewith increasing its lipid-binding capacity. Using CEST-NMR, we reveal that alpha synuclein interacts with isolated synaptic vesicles with two regions, the N terminus, already known from studies on SUVs, and additionally via its C terminus, which is regulated by the binding of calcium. Indeed, dSTORM on synaptosomes shows that calcium mediates the localization of alpha-synuclein at the pre-synaptic terminal, and an imbalance in calcium or alpha-synuclein can cause synaptic vesicle clustering, as seen ex vivo and in vitro. This study provides a new view on the binding of alpha-synuclein to synaptic vesicles, which might also affect our understanding of synucleinopathies. PMID- 29459794 TI - Impaired Cardiac Function in Patients with Multiple Sclerosis by Comparison with Normal Subjects. AB - Multiple sclerosis (MS), neurologic disease affecting young population, may cause cardiovascular dysfunction, due to autonomous nervous dysfunction, physical invalidity, increased oxidative stress, and systemic inflammatory status. However, cardiovascular function is rarely evaluated in these patients. We assessed left and right ventricular (LV and RV) function by 2D, 3D, tissue Doppler, and speckle tracking echocardiography, and vascular function by remodeling, stiffness, and endothelial dysfunction parameters in patients with MS, compared to control subjects. 103 subjects (35 +/- 10 years,70 women) were studied: 67 patients with MS and 36 control subjects. Patients with MS had decreased LV systolic function, confirmed by lower 2D and 3D ejection fraction, mitral annular plane systolic excursion, longitudinal myocardial systolic velocities, and 2D and 3D global longitudinal strain. The RV function was also decreased, as demonstrated by lower fractional area change, tricuspid annular plane systolic excursion, longitudinal systolic velocities, and longitudinal strain. Additionally, LV diastolic and left atrial (LA) function were decreased compared to controls. The parameters of arterial and endothelial function were similar between groups. Patients with MS have impaired biventricular function by comparison with normal subjects, with reduced LA function, but normal arterial and endothelial function. The noninvasive echocardiographic techniques might help to determine patients with MS at risk of developing cardiovascular dysfunction. PMID- 29459795 TI - High sensitization efficiency and energy transfer routes for population inversion at low pump intensity in Er organic complexes for IR amplification. AB - Organic erbium complexes have long been of interest due to their potential for using the strong absorption into the organic to sensitise the erbium emission. Despite this interest there is remarkably little quantitative information on how effective the approach is and the discussion of the energy transfer mechanism is generally vague. Here we accurately quantify the sensitisation as a function of excitation pump density and model it using a rate equation approach. As a result, we can calculate the degree of population inversion for the erbium ions as a function of the pump intensity. We demonstrate that even when we increase the erbium concentration in the films from ~10 to ~80% we find a relatively small decrease in the sensitisation which we attribute to the large (>20 A) Forster radius for the sensitisation process. We show that we can obtain population inversion in our films at very low pump powers ~600 mW/cm2. The calculated Forster radius for the organic erbium complexes suggests design rules for energy transfer between antennas and erbium ions in molecular systems and hybrid organic inorganic nanoparticles.

AB - OBJECTIVE: To determine whether localization and size are related to the presence of high-grade dysplasia of colon adenomas in patients of a Peruvian hospital. MATERIALS AND METHODS: This is a descriptive transversal study. We checked colonoscopyreports of 2014-2015 years of Hospital Daniel Alcides Carrion, we included the polyps found in patients older than 18 years old, and excluded reports from patients with colorectal cancer, an antecedent of oncological surgery, inflammatory bowel disease and polyposis (6 or more). We used data based on localization (proximal and distal colon, based on the splenic angle), size (less than 10 mm and 10 mm or more), shape (pediculate and sessile) and grade of dysplasia (low and high-grade). We calculated the strength of association by OR, and we determined whether there was association by Chi-square test with a significance value less than 0.05. RESULTS: We reviewed a total of 1710 of colonoscopy reports, 378 patients had polyps, so the adenoma detection rate was 22.1%. There were 458 polyps, from which 254 were adenomas. From these adenomas, we found an association between distal colon localization and high-grade dysplasia (OR 2.68 IC 1.12-6.42, p < 0.05); likewise, there was an association between the size of the adenomas and high-grade dysplasia (OR 7.75 IC 3.05-19.69, p<0.05). We did not find any association between the shape and grade of dysplasia. CONCLUSION: This study concludes that there is an association between the size of 10 mm or more and localization in the distal colon with high-grade dysplasia of adenomas.

AB - INTRODUCTION: Patients with large non-pedunculated colorectal polyps (L-NPCP) have been traditionally treated with surgery. Advances in therapeutic endoscopy allow endoscopic resection of these lesions and can be considered as an alternative to surgery. OBJECTIVE: To evaluate the efficacy and safety of endoscopic resection in patients with L-NPCP. METHODS: A prospective multicentric cohort. All patients referred for endoscopic resection with L-NPCP between January 2012 and December 2015, followed until August 2016, were included. Rates of successful resection, recurrence and complications were obtained. Predictive factors associated with unsuccessful resection and recurrence were analyzed. RESULTS: 115 L-NPCP in 107 patients were included. The rate of successful resection was 92%. The most common complications were bleeding (8.7%) and perforation (2.6%). The recurrence rate was 7%, all successfully treated with a new endoscopic session. Predictors of unsuccessful resection were a measure >50 mm of the lesion and the presence of fibrosis; and the only predictor of recurrence was a size of the polyp resected >50 mm. CONCLUSIONS: Endoscopic resection of L-NPCP is very efficacious and safe. PMID- 29459800 TI - [Andean megacolon and sigmoid volvulus in the high altitude.

AB - INTRODUCTION: Celiac disease (CD) is increasingly diagnosed and weight changes are common after adoption of a glutenfree diet (GFD) and there is concern that patients might gain further weight on a GFD. OBJECTIVES: This study examined to evaluate the impact of a GFD on the body mass index (BMI), whether favorable or unfavorable. MATERIALS AND METHODS: In this retrospective study, we reviewed electronic records of 44 patients with serologic study and intestinal biopsy confirmed CD who was visited in Nemazee hospital, Shiraz. All patients were put on GFD for 2 years and followed closely by pediatric gastroenterologist. BMIs were categories to four group underweight, normal weight, overweight and obese. Initial BMI and follow-up BMI was comparing together and also compared with general population. RESULT: At diagnosis, 27.27% of subjects were underweight, 63.64% normal and 9.09% were obese. On a GFD, 66.66% of underweight patients gained weight and became normal weight and 25% of normal weight and 75% of obese patients had increase weight; and the rest of the patients, BMI remained stable. The follow-up BMIs were statistically higher than initial BMIs (mean 17.17 vs. 15.62, p <0.0001). CONCLUSION: Individuals with celiac disease have lower BMI than the regional population at diagnosis. On the GFD, BMI is increased significantly in all categories. PMID- 29459802 TI - Diagnostic and therapeutic cholangioscopy in biliary diseases: a prospective study in Peru. AB - INTRODUCTION: Cholangioscopy is a test that allows the evaluation of the biliary epithelium. It is used for diagnosis and management of biliary diseases. OBJECTIVES: Determine the success rate of complete removal of difficult stones with the use of laser lithotripsy through cholangioscopy as well as its complications. Determine the visual impression accuracy of bile duct injuries. MATERIALS AND METHODS: This is a prospective and descriptive study. We included 39 patients between July 2016 and July 2017 with diagnosis of difficult stones in the biliary tract and indeterminate stenosis of the biliary tract that were submitted to cholangioscopy. RESULTS: Success rate of complete removal of difficult stones was 65.3%, there was one complication. Two laser sessions were required in 4 of the 17 patients who obtained complete removal of the stones. The visual impression accuracy of lesions in the bile duct to determine malignancy coincided in all cases with the final diagnosis of the patient. CONCLUSIONS: Laser lithotripsy allows a safe and effective treatment of the difficult stones of the bile duct. Precession of visual impression of lesions in the bile duct is very high.

AB - INTRODUCTION: Lymphocytic colitis and microscopic enteritis are relatively common causes of chronic diarrhea and it is characterized by an intraepithelial lymphocytic infiltrate. There have been no previous reports of coexistence between these 2 pathologies. OBJECTIVE: To describe histological and clinical characteristic in patients with coexistence of lymphocytic colitis and microscopic enteritis. MATERIAL AND METHODS: All cases with simultaneous diagnosis of lymphocytic duodenosis and lymphocytic colitis were reevaluated during lapse time 2010-2016 in hospital Daniel Carrion. The slides were reviewed by 3 pathologists and clinical information was obtained from clinical records. Expression of CD3 and CD8 was detected in 6 cases by immunohistochemical assays. RESULTS: A total of 35 patients with coexistence of lymphocytic duodenitis and lymphocytic colitis were selected of the pathology archives, 80% were females, Anemia was identified in 28.5% of patients. Blastocysitis hominis infestation was identified in 31.8%. The mean intraepithelial lymphocyte CD8 and CD3 positive was 40% in microscopic enteritis, while the mean intraepithelial lymphocyte CD3 positive was 37.2% and CD8 positive was 29.2% Additionally, lymphocytic ileitis was diagnosed in 11 of our cases. Eosinophilic colitis was diagnosed in 9 cases of lymphocytic colitis Conclusion: We found that lymphocytic colitis, microscopic enteritis and even lymphocytic ileitis can coexist in a group of patients with chronic diarrhea. These findings bring the question if this concurrence of both pathologies constituted a more generalized gastrointestinal disorder, involving both the large and the small intestines.

Often it occurs when the bile duct merges with the cystic duct; and they have been ranked by Strasberg and Bismuth, depending on the degree and level of injury. About third of IBDI recognized during LC, to detect bile leakage. No immediate repair is recommended, especially when the lesion is near the confluence or inflammation is associated. The drain should be established to control leakage of bile and prevent biliary peritonitis, before transferring the patient to a specialist in complex hepatobiliary surgery facility. In patients who are not recognized intraoperatively, the IBDI manifest late postoperative fever, abdominal pain, peritonitis or obstructive jaundice. If there is bile leak, percutaneous cholangiography should be done to define the biliary anatomy, and control leakage through percutaneous biliary stent. The repair is performed six to eight weeks after patient stabilization. If there is biliary obstruction, cholangiography and biliary drainage are indicated to control sepsis before repair. The ultimate aim is to restore the flow of bile into the gastrointestinal tract to prevent the formation of calculi, stenosis, cholangitis and biliary cirrhosis. Hepatojejunostomy with Roux-Y anastomosis termino-lateral without biliary stents long term, is the best choice for the repair of most common bile duct injury.

AB - Primary biliary cholangitis (PBC) is a chronic autoimmune cholangiopathy characterized by a selective destruction of biliary epithelial cells of small and medium caliber hepatic ducts, which mainly affects women. The main symptoms are fatigue and pruritus, however, a large proportion of patients may be asymptomatic. The diagnosis is based on AMA titers >1:40, alkaline phosphatase >1.5 times the upper limit for more than 24 weeks and compatible liver histology. It is associated with multiple autoimmune diseases mainly extrahepatic, thyroid diseases, bone diseases, among others. The first line treatment is ursodeoxycholic acid (UDCA), that improves liver function tests and delay the progression to cirrhosis. Currently, there are new treatments and adjuvant therapies on study. The purpose of this review is to offer an update in this topic, which is very important in gastroenterology and internal medicine.

AB - We report the case of a male patient, 80 years old, with a history of dyspepsia and no family history of neoplasias. In the upper digestive endoscopy in the distal esophagus, a flat depressed lesion with the appearance of early carcinoma, type IIC of Paris classification, was diagnosed by biopsy as a squamous carcinoma in situ, infiltrating, moderately differentiated non-keratinizing grade II carcinoma. He underwent submucosal endoscopic dissection without complications. Histopathology concluded: carcinoma of squamous cells, predominantly in situ of distal esophagus, measuring 0.6 cm, with focus of 0.1 cm of infiltration in the own lamina; absence of angiolymphatic or perineural invasion. The histopathology specimen had margins of surgical resection free of neoplasia. Stage pT1a. Three months later, in the endoscopy control with biopsy of the area, there was no evidence of carcinoma. We present the case because it is still a challenge to establish the diagnosis of esophageal cancer at an early stage, especially in patients without symptoms, highlighting the importance of chromoendoscopy and a good endoscopic examination to reach the diagnosis. Submucosal endoscopy dissection could be considered as a safe and effective alternative treatment to radical surgery.

AB - Pancreatic cancer is the second most common malignancy of the gastrointestinal tract in the US, and adenocarcinoma has been identified as the most common type of pancreatic cancer. Different types of pancreatic cancers have been classified: adenocarcinoma, ductal adenosquamous carcinoma, solid pseudopapillary tumors, endocrine neoplasms, acinar cell carcinoma, squamous cell carcinoma, cystic tumors, primary lymphoma of the pancreas, and metastatic lesions of the pancreas. Adenosquamous carcinoma is extremely rare, behave in a very aggressive way and is responsible for the 1 to 4% of the pancreatic exocrine neoplastic lesions. We describe the case of an 82-years-old African American female, presenting to our institution with quantifiable weight loss (12 kg in 3 months), jaundice and abdominal pain. On admission, laboratory tests were obtained: total bilirubin: 11.07 mg/dl with a direct fraction of 10.32 mg/dl. Cross-sectional abdominal CT scan with contrast, showed a lesion localized in the pancreatic head (hypodense on T1, measuring 3.5 x 3.5 x 2.5 cm), with vascular invasion of the portal vein. EUS showed a solid, hypoechoic, not well-defined lesion (measuring 3.98 x 3.80 cm), localized between the head and neck of the pancreas. EUS-FNA was performed with a 22G needle using the fanning technique. The cytological specimens demonstrated components of both squamous carcinoma and adenocarcinoma. The patient underwent ERCP procedure, and biliary drainage was performed with an entirely covered metallic stent placement. After a month from the procedures, the patient died due to the severity of the disease. Endoscopic ultrasound has proven to be the best method to diagnose solid pancreatic lesions, including rare and aggressive type of tumors like primary adenosquamous cell carcinoma that we described in this very interesting case report.

AB - The giant cystic pheochromocytoma is a rare adrenal tumor in the predominantly asymptomatic course; so many cases are not diagnosed until the time of surgery. The simple mobilization of the tumor is associated with the passage to the blood of large amounts of catecholamines and high morbidity and mortality. So the surgery itself and perioperative management are a huge challenge. This article describes the case of a malignant giant pheochromocytoma (35 cm) which occupied the entire right abdomen. Even with the preoperative diagnosis of pheochromocytoma, pharmacological blockade preoperative and intraoperative measures, the patient died shortly before the end of surgery.

PMID- 29459816 TI - Genetic Algorithm-Based Model Order Reduction of Aeroservoelastic Systems with Consistent States. AB - This paper presents a model order reduction framework to construct linear parameter-varying reduced-order models of flexible aircraft for aeroservoelasticity analysis and control synthesis in broad two-dimensional flight parameter space. Genetic algorithms are used to automatically determine physical states for reduction and to generate reduced-order models at grid points within parameter space while minimizing the trial-and-error process. In addition, balanced truncation for unstable systems is used in conjunction with the congruence transformation technique to achieve locally optimal realization and "weak" fulfillment of state consistency across the entire parameter space. Therefore, aeroservoelasticity reduced-order models at any flight condition can be obtained simply through model interpolation. The methodology is applied to the pitch-plant model of the X-56A Multi-Use Technology Testbed currently being tested at NASA Armstrong Flight Research Center for flutter suppression and gust load alleviation. The present studies indicate that the reduced-order model with more than 12* reduction in the number of states relative to the original model is able to accurately predict system response among all input-output channels. The genetic-algorithm-guided approach exceeds manual and empirical state selection in terms of efficiency and accuracy. The interpolated aeroservoelasticity reduced order models exhibit smooth pole transition and continuously varying gains along a set of prescribed flight conditions, which verifies consistent state representation obtained by congruence transformation. The present model order reduction framework can be used by control engineers for robust aeroservoelasticity controller synthesis and novel vehicle design.

AB - Huntington's disease (HD) is an autosomal dominant neurodegenerative disorder characterized by a progressive movement disorder, psychiatric symptoms, and cognitive impairments. HD is caused by a CAG repeat expansion encoding a stretch of polyglutamine residues in the N-terminus of mutant huntingtin (mHTT) protein. Proteolytic processing of mHTT yields toxic fragments, which cause neurotoxicity and massive neuronal cell death predominantly in the striatum and cortex. Inhibition of mHTT cleavage reduces neuronal toxicity suggesting mHTT proteolysis contributes to HD pathogenesis. A previously conducted unbiased siRNA screen in our lab for known human proteases identified matrix metalloproteinases (MMPs) as modifiers of mHTT proteolysis and toxicity. To further study MMP activation in HD, isogenic HD, and control corrected (C116) neural stem cells (NSCs) prepared from HD patient-derived induced pluripotent stem cells were used to examine the role of MMPs and their endogenous inhibitors in this highly relevant model system. We found altered expression of MMP-2 and MMP-9 (gelatinases), MMP-3/10, and MMP-14, activity in HD-NSCs when compared to control C116-NSCs. Dysregulation in MMP activity was accompanied with concomitant changes in levels of endogenous inhibitors of MMPs, called tissue inhibitors of matrix metalloproteinases (TIMPs). Specifically, we observed decreased levels of TIMP-1 and TIMP-2 in HD NSCs, suggesting part of the altered expression and activity of MMPs is due to lower abundance of these endogenous inhibitors. Immunofluorescence analysis revealed increased MMP/TIMP localization in the nucleus or aggregates of HD-NSCs, suggesting potential interaction with mHTT. TIMP-1 was found to associate with mHTT aggregates in discrete punctate structures in HD-NSCs. These events collectively contribute to increased neurotoxicity in HD. Previous characterization of these NSCs revealed transforming growth factor beta (TGF beta) pathway as the top dysregulated pathway in HD. TGF-beta was significantly upregulated in HD-NSCs and addition of TGF-beta to HD-NSCs was found to be neuroprotective. To determine if TGF-beta regulated MMP and TIMP activity, C116- and HD-NSCs were exogenously treated with recombinant TGF-beta. TIMP-1 levels were found to be elevated in response to TGF-beta treatment, representing a potential mechanism through which elevated TGF-beta levels confer neuroprotection in HD. Studying the mechanism of action of MMPs and TIMPs, and their interactions with mHTT in human isogenic patient-derived NSCs elucidates new mechanisms of HD neurotoxicity and will likely provide novel therapeutics for treatment of HD.

AB - The member of synthetic cathinone family, methylenedioxypyrovalerone (MDPV), is a frequently used psychoactive drug of abuse. The objective of our study was to determine the effect of MDPV (administered from the 8th to the 14th day of gestation) on the behavior of neonatal and adolescent mice, as well as its effect on maternal care. We measured maternal care (pup retrieval test, nest building), locomotor activity (open field test), and motor coordination (grip strength test) of dams, whereas on pups we examined locomotor activity at postnatal day 7 and day 21 (open field test) and motor coordination on day 21 (grip strength test). On fresh-frozen brain samples of the dams we examined the expression of two important peptides implicated in the regulation of maternal behavior and lactation: tuberoinfundibular peptide 39 (TIP39) mRNA in the thalamic posterior intralaminar complex, and amylin mRNA in the medial preoptic nucleus. We detected decreased birth rate and survival of offspring, and reduced maternal care in the drug-treated animals, whereas there was no difference between the motility of treated and control mothers. Locomotor activity of the pups was increased in the MDPV treated group both at 7 and 21 days of age, while motor coordination was unaffected by MDPV treatment. TIP39 and amylin were detected in their typical location but failed to show a significant difference of expression between the drug-treated and control groups. The results suggest that chronic systemic administration of the cathinone agent MDPV to pregnant mice can reduce birth rate and maternal care, and it also enhances motility (without impairment of motor coordination) of the offspring. PMID- 29459819 TI - Ganglioside Metabolism and Parkinson's Disease. AB - Here we advance the hypothesis that Parkinson's disease (PD) is fundamentally a failure of trophic support for specific classes of neurons, primarily catecholaminergic. Evidence from our laboratory provides a framework into which a broad array of findings from many quarters can be integrated into a general theory that offers testable hypotheses to new and established investigators. Mice deficient in the ability to synthesize series-a gangliosides, specifically GM1 ganglioside, develop parkinsonism. We found that this seems to be due to a failure in signaling efficiency by the important catecholaminergic growth factor, GDNF. Interestingly, these mice accumulate alpha-synuclein in nigral neurons. Striatal over-expression of GDNF eliminates these aggregates and also restores normal motor function. These findings bring into question common beliefs about alpha-synuclein pathology and may help us to reinterpret other experimental findings in a new light. The purpose of this article is to provoke new thinking about PD and hopefully encourage younger scientists to explore some of the ideas presented below. PMID- 29459820 TI - High Throughput Measurement of Locomotor Sensitization to Volatilized Cocaine in Drosophila melanogaster. AB - Drosophila melanogaster can be used to identify genes with novel functional roles in neuronal plasticity induced by repeated consumption of addictive drugs. Behavioral sensitization is a relatively simple behavioral output of plastic changes that occur in the brain after repeated exposures to drugs of abuse. The development of screening procedures for genes that control behavioral sensitization has stalled due to a lack of high-throughput behavioral tests that can be used in genetically tractable organism, such as Drosophila. We have developed a new behavioral test, FlyBong, which combines delivery of volatilized cocaine (vCOC) to individually housed flies with objective quantification of their locomotor activity. There are two main advantages of FlyBong: it is high throughput and it allows for comparisons of locomotor activity of individual flies before and after single or multiple exposures. At the population level, exposure to vCOC leads to transient and concentration-dependent increase in locomotor activity, representing sensitivity to an acute dose. A second exposure leads to further increase in locomotion, representing locomotor sensitization. We validate FlyBong by showing that locomotor sensitization at either the population or individual level is absent in the mutants for circadian genes period (per), Clock (Clk), and cycle (cyc). The locomotor sensitization that is present in timeless (tim) and pigment dispersing factor (pdf) mutant flies is in large part not cocaine specific, but derived from increased sensitivity to warm air. Circadian genes are not only integral part of the neural mechanism that is required for development of locomotor sensitization, but in addition, they modulate the intensity of locomotor sensitization as a function of the time of day. Motor-activating effects of cocaine are sexually dimorphic and require a functional dopaminergic transporter. FlyBong is a new and improved method for inducing and measuring locomotor sensitization to cocaine in individual Drosophila. Because of its high-throughput nature, FlyBong can be used in genetic screens or in selection experiments aimed at the unbiased identification of functional genes involved in acute or chronic effects of volatilized psychoactive substances. PMID- 29459821 TI - Pre- and Postsynaptic Activation of GABAB Receptors Modulates Principal Cell Excitation in the Piriform Cortex. AB - The piriform cortex (PC), like other cortical regions, normally operates in a state of dynamic equilibrium between excitation and inhibition. Here we examined the roles played by pre- and postsynaptic GABAB receptors in maintaining this equilibrium in the PC. Using whole-cell recordings in brain slices from the anterior PC of mice, we found that synaptic activation of postsynaptic GABAB receptors hyperpolarized the two major classes of layer 2 principal neurons and reduced the intrinsic electrical excitability of these neurons. Presynaptic GABAB receptors are expressed on the terminals of associational (intracortical) glutamatergic axons in the PC. Heterosynaptic activation of these receptors reduced excitatory associational inputs onto principal cells. Presynaptic GABAB receptors are also expressed on the axons of GABAergic interneurons in the PC, and blockade of these autoreceptors enhanced inhibitory inputs onto principal cells. Hence, presynaptic GABAB autoreceptors produce disinhibition of principal cells. To study the functional consequences of GABAB activation in vivo, we used 2-photon calcium imaging to simultaneously monitor the activity of ~200 layer 2 neurons. Superfusion of the GABAB agonist baclofen reduced spontaneous random firing but also promoted synchronous epileptiform activity. These findings suggest that, while GABAB activation can dampen excitability by engaging pre- and postsynaptic GABAB heteroreceptors on glutamatergic neurons, it can also promote excitability by disinhibiting principal cells by activating presynaptic GABAB autoreceptors on interneurons. Thus, depending on the dynamic balance of hetero- and autoinhibition, GABAB receptors can function as variable modulators of circuit excitability in the PC.

AB - The cerebrospinal fluid (CSF) occupies the brain's ventricles and subarachnoid space and, together with the interstitial fluid (ISF), forms a continuous fluidic network that bathes all cells of the central nervous system (CNS). As such, the CSF is well positioned to actively distribute neuromodulators to neural circuits in vivo via volume transmission. Recent in vitro experimental work in brain slices and neuronal cultures has shown that human CSF indeed contains neuromodulators that strongly influence neuronal activity. Here we briefly summarize these new findings and discuss their potential relevance to neural circuits in health and disease. PMID- 29459823 TI - Effects of Social Experience on the Habituation Rate of Zebrafish Startle Escape Response: Empirical and Computational Analyses. AB - While the effects of social experience on nervous system function have been extensively investigated in both vertebrate and invertebrate systems, our understanding of how social status differentially affects learning remains limited. In the context of habituation, a well-characterized form of non associative learning, we investigated how the learning processes differ between socially dominant and subordinate in zebrafish (Danio rerio). We found that social status and frequency of stimulus inputs influence the habituation rate of short latency C-start escape response that is initiated by the Mauthner neuron (M cell). Socially dominant animals exhibited higher habituation rates compared to socially subordinate animals at a moderate stimulus frequency, but low stimulus frequency eliminated this difference of habituation rates between the two social phenotypes. Moreover, habituation rates of both dominants and subordinates were higher at a moderate stimulus frequency compared to those at a low stimulus frequency. We investigated a potential mechanism underlying these status dependent differences by constructing a simplified neurocomputational model of the M-cell escape circuit. The computational study showed that the change in total net excitability of the model M-cell was able to replicate the experimental results. At moderate stimulus frequency, the model M-cell with lower total net excitability, that mimicked a dominant-like phenotype, exhibited higher habituation rates. On the other hand, the model with higher total net excitability, that mimicked the subordinate-like phenotype, exhibited lower habituation rates. The relationship between habituation rates and characteristics (frequency and amplitude) of the repeated stimulus were also investigated. We found that habituation rates are decreasing functions of amplitude and increasing functions of frequency while these rates depend on social status (higher for dominants and lower for subordinates). Our results show that social status affects habituative learning in zebrafish, which could be mediated by a summative neuromodulatory input to the M-cell escape circuit, which enables animals to readily learn to adapt to changes in their social environment. PMID- 29459824 TI - EGR3 Immediate Early Gene and the Brain-Derived Neurotrophic Factor in Bipolar Disorder. AB - Bipolar disorder (BD) is a severe psychiatric illness with a consistent genetic influence, involving complex interactions between numerous genes and environmental factors. Immediate early genes (IEGs) are activated in the brain in response to environmental stimuli, such as stress. The potential to translate environmental stimuli into long-term changes in brain has led to increased interest in a potential role for these genes influencing risk for psychiatric disorders. Our recent finding using network-based approach has shown that the regulatory unit of early growth response gene 3 (EGR3) of IEGs family was robustly repressed in postmortem prefrontal cortex of BD patients. As a central transcription factor, EGR3 regulates an array of target genes that mediate critical neurobiological processes such as synaptic plasticity, memory and cognition. Considering that EGR3 expression is induced by brain-derived neurotrophic factor (BDNF) that has been consistently related to BD pathophysiology, we suggest a link between BDNF and EGR3 and their potential role in BD. A growing body of data from our group and others has shown that peripheral BDNF levels are reduced during mood episodes and also with illness progression. In this same vein, BDNF has been proposed as an important growth factor in the impaired cellular resilience related to BD. Taken together with the fact that EGR3 regulates the expression of the neurotrophin receptor p75NTR and may also indirectly induce BDNF expression, here we propose a feed-forward gene regulatory network involving EGR3 and BDNF and its potential role in BD. PMID- 29459825 TI - Aging Potentiates Lateral but Not Local Inhibition of Orientation Processing in Primary Visual Cortex. AB - Aging-related declines in vision can decrease well-being of the elderly. Concerning early sensory changes as in the primary visual cortex, physiological and behavioral reports seem contradictory. Neurophysiological studies on orientation tuning properties suggested that neuronal changes might come from decreased cortical local inhibition. However, behavioral results either showed no clear deficits in orientation processing in older adults, or proposed stronger surround suppression. Through psychophysical experiments and computational modeling, we resolved these discrepancies by suggesting that lateral inhibition increased in older adults while neuronal orientation tuning widths, related to local inhibition, stayed globally intact across age. We confirmed this later result by re-analyzing published neurophysiological data, which showed no systematic tuning width changes, but instead displayed a higher neuronal noise with aging. These results suggest a stronger lateral inhibition and mixed effects on local inhibition during aging, revealing a more complex picture of age-related effects in the central visual system than people previously thought. PMID- 29459826 TI - Age Effects in Postural Control Analyzed via a Principal Component Analysis of Kinematic Data and Interpreted in Relation to Predictions of the Optimal Feedback Control Theory. AB - Optimal feedback control theory suggests that control of movement is focused on movement dimensions that are important for the task's success. The current study tested the hypotheses that age effects would emerge in the control of only specific movement components and that these components would be linked to the task relevance. Fifty healthy volunteers, 25 young and 25 older adults, performed a 80s-tandem stance while their postural movements were recorded using a standard motion capture system. The postural movements were decomposed by a principal component analysis into one-dimensional movement components, PMk, whose control was assessed through two variables, Nk and sigmak, which characterized the tightness and the regularity of the neuro-muscular control, respectively. The older volunteers showed less tight and more irregular control in PM2 (N2: -9.2%, p = 0.007; sigma2: +14.3.0%, p = 0.017) but tighter control in PM8 and PM9 (N8: +4.7%, p = 0.020; N9: +2.5%, p = 0.043; sigma9: -8.8%, p = 0.025). These results suggest that aging effects alter the postural control system not as a whole, but emerge in specific, task relevant components. The findings of the current study thus support the hypothesis that the minimal intervention principle, as described in the context of optimal feedback control (OFC), may be relevant when assessing aging effects on postural control. PMID- 29459827 TI - Rosmarinic Acid Activates AMPK to Inhibit Metastasis of Colorectal Cancer. AB - Rosmarinic acid (RA) has been used as an anti-inflammatory, anti-diabetic, and anti-cancer agent. Although RA has also been shown to exert an anti-metastatic effect, the mechanism of this effect has not been reported to be associated with AMP-activated protein kinase (AMPK). The aim of this study was to elucidate whether RA could inhibit the metastatic properties of colorectal cancer (CRC) cells via the phosphorylation of AMPK. RA inhibited the proliferation of CRC cells through the induction of cell cycle arrest and apoptosis. In several metastatic phenotypes of CRC cells, RA regulated epithelial-mesenchymal transition (EMT) through the upregulation of an epithelial marker, E-cadherin, and the downregulation of the mesenchymal markers, N-cadherin, snail, twist, vimentin, and slug. Invasion and migration of CRC cells were inhibited and expressions of matrix metalloproteinase (MMP)-2 and MMP-9 were decreased by RA treatment. Adhesion and adhesion molecules such as ICAM-1 and integrin beta1 expressions were also reduced by RA treatment. In particular, the effects of RA on EMT and MMPs expressions were due to the activation of AMPK. Moreover, RA inhibited lung metastasis of CRC cells by activating AMPK in mouse model. Collectively, these results proved that RA could be potential therapeutic agent against metastasis of CRC. PMID- 29459828 TI - Nature-Based Tourism Elicits a Phenotypic Shift in the Coping Abilities of Fish. AB - Nature-based tourism is gaining extensive popularity, increasing the intensity and frequency of human-wildlife contacts. As a consequence, behavioral and physiological alterations were observed in most exposed animals. However, while the majority of these studies investigated the effects of punctual exposure to tourists, the consequences of constant exposition to humans in the wild remains overlooked. This is an important gap considering the exponential interest for recreational outdoor activities. To infer long-term effects of intensive tourism, we capitalized on Odontostilbe pequira, a short-lived sedentary Tetra fish who spends its life close to humans, on which it feeds on dead skin. Hence, those fish are constantly exposed to tourists throughout their lifecycle. Here we provide an integrated picture of the whole phenomenon by investigating, for the first time, the expression of genes involved in stress response and neurogenesis, as well as behavioral and hormonal responses of animals consistently exposed to tourists. Gene expression of the mineralocorticoid (and cortisol) receptor (mr) and the neurogenic differentiation factor (NeuroD) were significantly higher in fish sampled in the touristic zone compared to those sampled in the control zone. Additionally, after a simulated stress in artificial and controlled conditions, those fish previously exposed to visitors produced more cortisol and presented increased behavioral signs of stress compared to their non-exposed conspecifics. Overall, nature-based tourism appeared to shift selection pressures, favoring a sensitive phenotype that does not thrive under natural conditions. The ecological implications of this change in coping style remain, nevertheless, an open question. PMID- 29459829 TI - Stimulation of JNK Phosphorylation by the PTTH in Prothoracic Glands of the Silkworm, Bombyx mori. AB - In this study, phosphorylation of c-Jun N-terminal kinase (JNK) by the prothoracicotropic hormone (PTTH) was investigated in prothoracic glands (PGs) of the silkworm, Bombyx mori. Results showed that JNK phosphorylation was stimulated by the PTTH in time- and dose-dependent manners. In vitro activation of JNK phosphorylation in PGs by the PTTH was also confirmed in an in vivo experiment, in which a PTTH injection greatly increased JNK phosphorylation in PGs of day-6 last instar larvae. JNK phosphorylation caused by PTTH stimulation was greatly inhibited by U73122, a potent and specific inhibitor of phospholipase C (PLC) and an increase in JNK phosphorylation was also detected when PGs were treated with agents (either A23187 or thapsigargin) that directly elevated the intracellular Ca2+ concentration, thereby indicating involvement of PLC and Ca2+. Pretreatment with an inhibitor (U0126) of mitogen-activated protein kinase (MAPK)/extracellular signal-regulated kinase (ERK) kinase (MEK) and an inhibitor (LY294002) of phosphoinositide 3-kinase (PI3K) failed to significantly inhibit PTTH-stimulated JNK phosphorylation, indicating that ERK and PI3K were not related to JNK. We further investigated the effect of modulation of the redox state on JNK phosphorylation. In the presence of either an antioxidant (N acetylcysteine, NAC) or diphenylene iodonium (DPI), PTTH-stimulated JNK phosphorylation was blocked. The JNK kinase inhibitor, SP600125, markedly inhibited PTTH-stimulated JNK phosphorylation and ecdysteroid synthesis. The kinase assay of JNK in PGs confirmed its stimulation by PTTH and inhibition by SP600125. Moreover, PTTH treatment did not affect JNK or Jun mRNA expressions. Based on these findings, we concluded that PTTH stimulates JNK phosphorylation in Ca2+- and PLC-dependent manners and that the redox-regulated JNK signaling pathway is involved in PTTH-stimulated ecdysteroid synthesis in B. mori PGs. PMID- 29459831 TI - Relative Handgrip Strength Is Inversely Associated with Metabolic Profile and Metabolic Disease in the General Population in China. AB - Background: Absolute handgrip strength has been correlated with metabolic profile and metabolic disease. Whether relative handgrip strength is also associated with metabolic disease has not been assessed. This study aimed at assessing the association of relative handgrip strength with metabolic profile and metabolic disease in the general population in China. Methods: Data were derived from an ongoing cross-sectional survey of the 2013 National Physical and Health in Shanxi Province, which involved 5520 participants. Multiple linear regression or multiple logistic regression analysis were used to assess the association of absolute/relative handgrip strength with the metabolic profile, preclinical, and established stages of metabolic diseases. Results: This study revealed that relative handgrip strength, that is when normalized to BMI, was associated with: (1) in both genders for more favorable blood lipid levels of high-density lipoprotein cholesterol [males: b = 0.19 (0.15, 0.23); females: b = 0.22 (0.17, 0.28)], low-density lipoprotein cholesterol [males: b = -0.14 (-0.23, -0.05); females: b = -0.19 (-0.31, -0.18)], triglycerides [males: b = -0.58 (-0.74, 0.43); females: b = -0.55 (-0.74, -0.36)] and total cholesterol [males: b = -0.20 (-0.31, -0.10); females: b = -0.19 (-0.32, -0.06)]; and better serum glucose levels in males [b = -0.30 (-0.46, -0.15)]. (2) lower risk of impaired fasting glucose in males {third quartile [OR = 0.66 (0.45-0.95)] and fourth quartile [OR = 0.46 (0.30-0.71)] vs. first quartile} and dyslipidemia in both genders {third quartile [males: OR = 0.65 (0.48-0.87); females: OR = 0.68 (0.53-0.86)] and fourth quartile [males: OR = 0.47 (0.35-0.64); females: OR = 0.47(0.36-0.61)] vs. first quartile}. (3) lower risk of hyperlipidemia in both genders third quartile [males: OR = 0.66 (0.50-0.87); females: OR = 0.57 (0.43-0.75)] and fourth quartile [males: OR = 0.35 (0.26-0.47); females: OR = 0.51 (0.38-0.70)] vs. first quartile. However, contrary to relative handgrip strength, higher absolute handgrip strength was associated with unfavorable metabolic profiles and higher risk of metabolic diseases. These paradoxical associations were retained even after adjusted for BMI by employed a multivariate analysis. Conclusion: We conclude that measurement of relative handgrip strength can be used as a reasonable clinical predictor of metabolic health and disease. PMID- 29459830 TI - Coenzyme Q10 Supplementation in Aging and Disease. AB - Coenzyme Q (CoQ) is an essential component of the mitochondrial electron transport chain and an antioxidant in plasma membranes and lipoproteins. It is endogenously produced in all cells by a highly regulated pathway that involves a mitochondrial multiprotein complex. Defects in either the structural and/or regulatory components of CoQ complex or in non-CoQ biosynthetic mitochondrial proteins can result in a decrease in CoQ concentration and/or an increase in oxidative stress. Besides CoQ10 deficiency syndrome and aging, there are chronic diseases in which lower levels of CoQ10 are detected in tissues and organs providing the hypothesis that CoQ10 supplementation could alleviate aging symptoms and/or retard the onset of these diseases. Here, we review the current knowledge of CoQ10 biosynthesis and primary CoQ10 deficiency syndrome, and have collected published results from clinical trials based on CoQ10 supplementation. There is evidence that supplementation positively affects mitochondrial deficiency syndrome and the symptoms of aging based mainly on improvements in bioenergetics. Cardiovascular disease and inflammation are alleviated by the antioxidant effect of CoQ10. There is a need for further studies and clinical trials involving a greater number of participants undergoing longer treatments in order to assess the benefits of CoQ10 treatment in metabolic syndrome and diabetes, neurodegenerative disorders, kidney diseases, and human fertility. PMID- 29459832 TI - Variations of the Functional Brain Network Efficiency in a Young Clinical Sample within the Autism Spectrum: A fNIRS Investigation. AB - Autism is a neurodevelopmental disorder with dimensional behavioral symptoms and various damages in the structural and functional brain. Previous neuroimaging studies focused on exploring the differences of brain development between individuals with and without autism spectrum disorders (ASD). However, few of them have attempted to investigate the individual differences of the brain features among subjects within the Autism spectrum. Our main goal was to explore the individual differences of neurodevelopment in young children with Autism by testing for the association between the functional network efficiency and levels of autistic behaviors, as well as the association between the functional network efficiency and age. Forty-six children with Autism (ages 2.0-8.9 years old) participated in the current study, with levels of autistic behaviors evaluated by their parents. The network efficiency (global and local network efficiency) were obtained from the functional networks based on the oxy-, deoxy-, and total Hemoglobin series, respectively. Results indicated that the network efficiency decreased with age in young children with Autism in the deoxy- and total Hemoglobin-based-networks, and children with a relatively higher level of autistic behaviors showed decreased network efficiency in the oxy-hemoglobin based network. Results suggest individual differences of brain development in young children within the Autism spectrum, providing new insights into the psychopathology of ASD. PMID- 29459834 TI - Suicidal Risk, Psychopathology, and Quality of Life in a Clinical Population of Adolescents. AB - Background: According to literature data, psychopathology is associated with both quality of life (QoL) and suicidal risk in adolescents, but the literature does not fully support a direct association between psychopathology and suicidal thoughts and behaviors. The aim of this study was to investigate the possible mediational role of QoL in the relationship between psychopathology and level of suicidal risk in a clinical sample of adolescents. Method: The authors examined a clinical population of 134 adolescents, aged 13-18 years. Suicidal risk-having any current suicidal ideations and/or previous suicide attempt-was assessed by the Mini International Neuropsychiatric Interview. QoL was evaluated by the adolescent self-rated versions of "Das Intervertar zur Erfassung der Lebensqualitat Kindern und Jugendlichen" (ILK: Measure of Quality of Life for Children and Adolescents) and psychopathology was measured by adolescent self rated versions of the Strengths and Difficulties Questionnaire (SDQ). A mediational model, in which QoL mediated the relationship between psychopathology and suicidal risk controlling for gender and age, was tested by means of regression analyses. Results: Gender and age were both associated with suicidal risk. Self-reported QoL significantly mediated the relationships between emotional problems (=1.846; 95% BCa CI: 0.731-2.577), as well as peer problems (=0.883; 95% BCa CI: 0.055-1.561) and suicidal risk: more emotional and peer problems were associated with lower QoL, which in turn was related to higher level of suicidal risk. Conclusion: Based on this study, which aims to make further steps in suicidal prevention, our findings suggest that clinicians should routinely screen the QoL of their patients, especially in adolescents with emotional and peer problems. Furthermore, it is important to focus intervention and treatment efforts on improving the QoL of adolescents with emotional and peer problems. PMID- 29459833 TI - Potential and Challenges for the Clinical Use of d-Serine As a Cognitive Enhancer. AB - After 25 years of its discovery in the rat brain, d-serine is a recognized modulator of synaptic plasticity and cognitive processes through its actions on the NMDA-glutamate receptor. Importantly, cognitive impairment is a core feature of conditions, such as schizophrenia, Alzheimer's disease, depression, and aging, and is associated to disturbances in NMDA-glutamate receptors. The d-serine pathway has been associated with cognitive deficits and these conditions, and, for this reason, d-serine signaling is subject of intense research to probe its role in aiding diagnosis and therapy. Nevertheless, this has not resulted in new therapies being incorporated into clinical practice. Therefore, in this review we will address many questions that need to be solved by future studies, regarding d serine pharmacokinetics, possible side effects, other strategies to modulate its levels, and combination with other therapies to increase its efficacy. PMID- 29459835 TI - Asymmetric Drug-Induced Parkinsonism and Psychopathology: A Prospective Naturalistic Study in Long-Stay Psychiatric Patients. AB - Background: Drug-induced parkinsonism (DIP) is the most common movement disorder induced by antipsychotics. Although DIP is mostly symmetric, asymmetric DIP is reported in a substantial part of the patients. We investigated the frequency of motor asymmetry in DIP and its relationship to the severity of psychopathology in long-stay psychiatric patients. Methods: We obtained data from a cohort study of 207 long-stay psychiatric patients on the frequency and risk factors of tardive dyskinesia, akathisia, tardive dystonia, and DIP. From July 2003 to May 2007 (mean follow-up, 1.1 year) drug-induced movement disorders were assessed at least two times in each patient, with a frequency of persistent DIP of 56.2%. All patients who had at least one time parkinsonism in the upper/lower limb(s) were included for analyses (190 patients, 79 women; mean age, 48.0 +/- 12.9 years). The Unified Parkinson Disease Rating Scale motor scale was used to calculate the frequency of asymmetric parkinsonism. Multilevel mixed models were built to explore the relationship between asymmetry in parkinsonism and the severity of psychopathology, measured on the Clinical Global Impression-Schizophrenia scale severity index (CGI-SCH SI). Results: The frequency of asymmetric parkinsonism was 20.8%. Asymmetry in parkinsonism was associated with symptom severity on all CGI-SCH SI scales (beta range, 0.37-3.74) and significantly associated with the positive symptom scale (beta, 3.74; 95% CI, 0.35-7.31). Conclusion: DIP is asymmetric in a substantial part of patients. Asymmetric presentation of DIP is of clinical relevance as it is related to the severity of psychopathology and may alert the clinician of more severe psychopathology. Future research is recommended to provide insight into the neuropsychopathology and clinical value of asymmetric parkinsonism for psychiatric patients. PMID- 29459837 TI - Effects of Relaxing and Arousing Music during Imagery Training on Dart-Throwing Performance, Physiological Arousal Indices, and Competitive State Anxiety. AB - Music that is carefully selected to match the requirements of activities and the characteristics of individuals has been shown to produce significant impacts on performance enhancement (Priest et al., 2004). There is also evidence that music can enhance imagery (Grocke and Wigram, 2007), although few studies have investigated the effects of music on imagery in the context of sport skills. In the present study, the effects of relaxing and arousing music during imagery on dart-throwing performance, physiological arousal indices, and competitive state anxiety, were investigated among 63 novice dart throwers. Participants had moderate-to-high imagery ability and were randomly assigned to unfamiliar relaxing music (URM), unfamiliar arousing music (UAM), or no music (NM) groups. Performance was assessed by 40 dart throws at a concentric circles dartboard before and after 12 imagery sessions over 4 weeks. Measures of galvanic skin response (GSR), peripheral temperature (PT), and heart rate (HR) were taken during imagery sessions 1 and 12, and the Competitive State Anxiety Inventory-2 Revised (CSAI-2R) was administered prior to the pre- and post-intervention performance task. Dart-throwing gain scores were significantly higher for URM than for UAM and NM, with no significant difference between UAM and NM (URM = 37.24 +/- 5.66, UAM = 17.57 +/- 5.30, and NM = 13.19 +/- 6.14, F2,62 = 5.03, p = 0.01, eta2 = 0.14). GSR, PT, and HR reflected lower arousal for URM than for UAM or NM. Significant decreases in somatic anxiety were evident for URM and UAM but not NM. Significant decreases in cognitive anxiety were evident for URM and NM but not UAM. Significant increases in self-confidence were evident for URM but not UAM or NM. Performance improved in all three conditions but URM was associated with the largest performance gain, the lowest physiological indices of arousal, and the most positive CSAI-2R profiles. Listening to relaxing music during imagery may have benefits for performance in other fine motor skills. PMID- 29459838 TI - Characterizing and Measuring Maliciousness for Cybersecurity Risk Assessment. AB - Cyber attacks have been increasingly detrimental to networks, systems, and users, and are increasing in number and severity globally. To better predict system vulnerabilities, cybersecurity researchers are developing new and more holistic approaches to characterizing cybersecurity system risk. The process must include characterizing the human factors that contribute to cyber security vulnerabilities and risk. Rationality, expertise, and maliciousness are key human characteristics influencing cyber risk within this context, yet maliciousness is poorly characterized in the literature. There is a clear absence of literature pertaining to human factor maliciousness as it relates to cybersecurity and only limited literature relating to aspects of maliciousness in other disciplinary literatures, such as psychology, sociology, and law. In an attempt to characterize human factors as a contribution to cybersecurity risk, the Cybersecurity Collaborative Research Alliance (CSec-CRA) has developed a Human Factors risk framework. This framework identifies the characteristics of an attacker, user, or defender, all of whom may be adding to or mitigating against cyber risk. The maliciousness literature and the proposed maliciousness assessment metrics are discussed within the context of the Human Factors Framework and Ontology. Maliciousness is defined as the intent to harm. Most maliciousness cyber research to date has focused on detecting malicious software but fails to analyze an individual's intent to do harm to others by deploying malware or performing malicious attacks. Recent efforts to identify malicious human behavior as it relates to cybersecurity, include analyzing motives driving insider threats as well as user profiling analyses. However, cyber-related maliciousness is neither well-studied nor is it well understood because individuals are not forced to expose their true selves to others while performing malicious attacks. Given the difficulty of interviewing malicious-behaving individuals and the potential untrustworthy nature of their responses, we aim to explore the maliciousness as a human factor through the observable behaviors and attributes of an individual from their actions and interactions with society and networks, but to do so we will need to develop a set of analyzable metrics. The purpose of this paper is twofold: (1) to review human maliciousness-related literature in diverse disciplines (sociology, economics, law, psychology, philosophy, informatics, terrorism, and cybersecurity); and (2) to identify an initial set of proposed assessment metrics and instruments that might be culled from in a future effort to characterize human maliciousness within the cyber realm. The future goal is to integrate these assessment metrics into holistic cybersecurity risk analyses to determine the risk an individual poses to themselves as well as other networks, systems, and/or users. PMID- 29459836 TI - Treating Depression with Transcutaneous Auricular Vagus Nerve Stimulation: State of the Art and Future Perspectives. AB - Depression is a highly prevalent disorder, and its treatment is far from satisfactory. There is an urgent need to develop a new treatment for depression. Although still at its early stage, transcutaneous auricular vagus nerve stimulation (taVNS) has shown promising potential for treating depression. In this article, we first summarize the results of clinical studies on the treatment effect of taVNS on depression. Then, we re-analyze a previous study to identify the specific symptoms taVNS can relieve as indicated by subscores of the 24-item Hamilton Depression Scale in patients with depression. We found that taVNS can significantly reduce multiple symptoms of depression patients, including anxiety, psychomotor retardation, sleep disturbance, and hopelessness. Next, we pose several hypotheses on the mechanism of taVNS treatment of depression, including directly and indirectly modulating the activity and connectivity of key brain regions involved in depression and mood regulation; inhibiting neuro-inflammatory sensitization; modulating hippocampal neurogenesis; and regulating the microbiome brain-gut axis. Finally, we outline current challenges and lay out the future directions of taVNS treatment of depression, which include (1) intensively comparing stimulation parameters and "dose effect" (treatment frequency and duration) to maximize the treatment effect of taVNS; (2) exploring the effect of taVNS on disorders comorbid with depression (such as chronic pain disorders, cardiovascular disorder, and autism) to provide new "two-for-one" treatment approaches for patients with these disorders; and (3) applying multiple scale methods to explore the underlying mechanism of taVNS. PMID- 29459839 TI - Psychological Characteristics in Talented Soccer Players - Recommendations on How to Improve Coaches' Assessment. AB - Psychological characteristics, including personality traits and psychological skills, have been shown to be relevant predictors of soccer performance. In research, general and sport specific standardized self-report questionnaires have been applied in psychological diagnostics of sports talent. However, with regard to the assessment of psychological characteristics of talented soccer players, a gap between research and practice is apparent. While soccer clubs often ask their coaches to assess their players on self-designed, unevaluated scouting sheets, research widely neglects expert coaches' and clubs' perspectives on relevant performance characteristics. As we believe that expert coaches' assessments could be a valid predictor of a player's current performance and future success, we provide recommendations on how to improve coaches' assessment of psychological characteristics. As the quality of the assessment of psychological characteristics is crucial, we provide recommendations on how to ensure the central diagnostic standards: objectivity, reliability, and validity in talent assessment. Further, we argue that assessing psychological characteristics should combine self ratings of players and external ratings of coaches in talent development. Sport psychologists should assist clubs and coaches in improving the diagnostics of psychological characteristics as well as in embedding psychological diagnostics and interventions in the talent development process. PMID- 29459840 TI - How Strong Is Your Coffee? The Influence of Visual Metaphors and Textual Claims on Consumers' Flavor Perception and Product Evaluation. AB - This study investigates the relative impact of textual claims and visual metaphors displayed on the product's package on consumers' flavor experience and product evaluation. For consumers, strength is one of the most important sensory attributes of coffee. The 2 * 3 between-subjects experiment (N = 123) compared the effects of visual metaphor of strength (an image of a lion located either on top or on the bottom of the package of coffee beans) and the direct textual claim ("extra strong") on consumers' responses to coffee, including product expectation, flavor evaluation, strength perception and purchase intention. The results demonstrate that both the textual claim and the visual metaphor can be efficient in communicating the product attribute of strength. The presence of the image positively influenced consumers' product expectations before tasting. The textual claim increased the perception of strength of coffee and the purchase intention of the product. The location of the image also played an important role in flavor perception and purchase intention. The image located on the bottom of the package increased the perceived strength of coffee and purchase intention of the product compared to the image on top of the package. This result could be interpreted from the perspective of the grounded cognition theory, which suggests that a picture in the lower part of the package would automatically activate the "strong is heavy" metaphor. As heavy objects are usually associated with a position on the ground, this would explain why perceiving a visually heavy package would lead to the experience of a strong coffee. Further research is needed to better understand the relationships between a metaphorical image and its spatial position in food packaging design. PMID- 29459841 TI - Electrophysiological Response to the Informative Value of Feedback Revealed in a Segmented Wisconsin Card Sorting Test. AB - Feedback has two main components. One is valence that indicates the wrong or correct behavior, and the other is the informative value that refers to what we can learn from feedback. Aimed to explore the neural distinction of these two components, we provided participants with a segmented Wisconsin Card Sorting Task, in which they received either positive or negative feedback at different steps. The informative value was manipulated in terms of the order of feedback presentation. The results of event-related potentials time-locked to the feedback presentation confirmed that valence of feedback was processed in a broad epoch, especially in the time window of feedback-related negativity (FRN), reflecting detection of correct or wrong card sorting behavior. In contrast, the informative value of positive and negative feedback was mainly processed in the P300, possibly reflecting information updating or hypothesis revision. These findings provide new evidence that informative values of feedback are processed by cognitive systems that differ from those of feedback valence. PMID- 29459842 TI - Robot Faces that Follow Gaze Facilitate Attentional Engagement and Increase Their Likeability. AB - Gaze behavior of humanoid robots is an efficient mechanism for cueing our spatial orienting, but less is known about the cognitive-affective consequences of robots responding to human directional cues. Here, we examined how the extent to which a humanoid robot (iCub) avatar directed its gaze to the same objects as our participants affected engagement with the robot, subsequent gaze-cueing, and subjective ratings of the robot's characteristic traits. In a gaze-contingent eyetracking task, participants were asked to indicate a preference for one of two objects with their gaze while an iCub avatar was presented between the object photographs. In one condition, the iCub then shifted its gaze toward the object chosen by a participant in 80% of the trials (joint condition) and in the other condition it looked at the opposite object 80% of the time (disjoint condition). Based on the literature in human-human social cognition, we took the speed with which the participants looked back at the robot as a measure of facilitated reorienting and robot-preference, and found these return saccade onset times to be quicker in the joint condition than in the disjoint condition. As indicated by results from a subsequent gaze-cueing tasks, the gaze-following behavior of the robot had little effect on how our participants responded to gaze cues. Nevertheless, subjective reports suggested that our participants preferred the iCub following participants' gaze to the one with a disjoint attention behavior, rated it as more human-like and as more likeable. Taken together, our findings show a preference for robots who follow our gaze. Importantly, such subtle differences in gaze behavior are sufficient to influence our perception of humanoid agents, which clearly provides hints about the design of behavioral characteristics of humanoid robots in more naturalistic settings. PMID- 29459843 TI - Hypothesis: The Vestibular and Cerebellar Basis of the Mal de Debarquement Syndrome. AB - The Mal de Debarquement syndrome (MdDS) generally follows sea voyages, but it can occur after turbulent flights or spontaneously. The primary features are objective or perceived continuous rocking, swaying, and/or bobbing at 0.2 Hz after sea voyages or 0.3 Hz after flights. The oscillations can continue for months or years and are immensely disturbing. Associated symptoms appear to be secondary to the incessant sensation of movement. We previously suggested that the illness can be attributed to maladaptation of the velocity storage integrator in the vestibular system, but the actual neural mechanisms driving the MdDS are unknown. Here, based on experiments in subhuman primates, we propose a series of postulates through which the MdDS is generated: (1) The MdDS is produced in the velocity storage integrator by activation of vestibular-only (VO) neurons on either side of the brainstem that are oscillating back and forth at 0.2 or 0.3 Hz. (2) The groups of VO neurons are driven by signals that originate in Purkinje cells in the cerebellar nodulus. (3) Prolonged exposure to roll, either on the sea or in the air, conditions the roll-related neurons in the nodulus. (4) The prolonged exposure causes a shift of the pitch orientation vector from its original position aligned with gravity to a position tilted in roll. (5) Successful treatment involves exposure to a full-field optokinetic stimulus rotating around the spatial vertical countering the direction of the vestibular imbalance. This is done while rolling the head at the frequency of the perceived rocking, swaying, or bobbing. We also note experiments that could be used to verify these postulates, as well as considering potential flaws in the logic. Important unanswered questions: (1) Why does the MdDS predominantly affect women? (2) What aspect of roll causes the prolongation of the tilted orientation vector, and why is it so prolonged in some individuals? (3) What produces the increase in symptoms of some patients when returning home after treatment, and how can this be avoided? We also posit that the same mechanisms underlie the less troublesome and shorter duration Mal de Debarquement.

AB - Advances in metabolic imaging techniques have allowed for more precise characterization of gliomas, particularly as it relates to tumor recurrence or pseudoprogression. Furthermore, the emerging field of radiogenomics where radiographic features are systemically correlated with molecular markers has the potential to achieve the holy grail of neuro-oncologic neuro-radiology, namely molecular diagnosis without requiring tissue specimens. In this section, we will review the utility of metabolic imaging and discuss the current state of the art related to the radiogenomics of glioblastoma. PMID- 29459845 TI - Levodopa-Induced Changes in Electromyographic Patterns in Patients with Advanced Parkinson's Disease. AB - Levodopa medication is the most efficient treatment for motor symptoms of Parkinson's disease (PD). Levodopa significantly alleviates rigidity, rest tremor, and bradykinesia in PD. The severity of motor symptoms can be graded with UPDRS-III scale. Levodopa challenge test is routinely used to assess patients' eligibility to deep-brain stimulation (DBS) in PD. Feasible and objective measurements to assess motor symptoms of PD during levodopa challenge test would be helpful in unifying the treatment. Twelve patients with advanced PD who were candidates for DBS treatment were recruited to the study. Measurements were done in four phases before and after levodopa challenge test. Rest tremor and rigidity were evaluated using UPDRS-III score. Electromyographic (EMG) signals from biceps brachii and kinematic signals from forearm were recorded with wireless measurement setup. The patients performed two different tasks: arm isometric tension and arm passive flexion-extension. The electromyographic and the kinematic signals were analyzed with parametric, principal component, and spectrum-based approaches. The principal component approach for isometric tension EMG signals showed significant decline in characteristics related to PD during levodopa challenge test. The spectral approach on passive flexion-extension EMG signals showed a significant decrease on involuntary muscle activity during the levodopa challenge test. Both effects were stronger during the levodopa challenge test compared to that of patients' personal medication. There were no significant changes in the parametric approach for EMG and kinematic signals during the measurement. The results show that a wireless and wearable measurement and analysis can be used to study the effect of levodopa medication in advanced Parkinson's disease. PMID- 29459846 TI - Vestibular Dysfunctions in Sudden Sensorineural Hearing Loss: A Systematic Review and Meta-analysis. AB - Background: Sudden sensorineural hearing loss (SSHL) not only involves cochlear function but might also be accompanied by vestibular disturbances. The assessment of vestibular function could be of great relevance in SSHL. Objective: To investigate the prevalence of vestibulocochlear lesions in SSHL and the correlation of specific vestibular organs with hearing prognosis. Data sources: A complete literature search of eligible studies in the PubMed and EMBASE databases was performed. Study selection: For our aim, studies that focused on vestibular examination in the case of SSHL were retrieved, including caloric tests, cervical vestibular-evoked myogenic potential (cVEMP) tests, or ocular vestibular-evoked myogenic potential (oVEMP) tests. Results: Of the 18 studies included, a caloric test was performed in 16 studies, cVEMP in 13 studies, and oVEMP in 5 studies, and together the studies included a total population of 1,468 subjects. The scores on the Agency for Healthcare Research and Quality (AHRQ) questionnaire ranged from 6 to 11. These results indicated that the most commonly damaged vestibular organ in SSHL was the utricle and superior vestibular pathway (U + S) followed by the lateral semicircular canal and superior vestibular pathway (LSC + S), the saccule and inferior vestibular pathway (S + I), and the cochlea only (C only). The meta-analysis indicated that SSHL patients with vertigo have a statistically increased risk of vestibular organ lesions compared with those without vertigo, including the LSC + S subgroup (OR = 4.89, 95% CI = 1.20-19.93, I2 = 80%, p = 0.03) and the S + I subgroup (OR = 3.58, 95% CI = 1.61-7.95, I2 = 0%, p = 0.002). The pooled possibility of hearing recovery within the LSC + S lesion group was less than half that of the non-LSC + S lesion group (OR = 0.24, 95% CI = 0.11-0.52, I2 = 68%, p = 0.0003). Conclusion: This study shows the relevance of vestibular damage concomitant with SSHL and that SSHL patients with vertigo are at an increased risk of vestibular organ lesions compared with patients without vertigo. LSC + S lesions thus appear to be a critical variable that influence the possibility of hearing improvement in SSHL.

PMID- 29459847 TI - Novel Approaches to the Diagnosis of Chronic Disorders of Consciousness: Detecting Peripersonal Space by Using Ultrasonics. AB - The assessment of behavioral responsiveness in patients suffering from chronic disorders of consciousness (DoC), including Unresponsive Wakefulness Syndrome (UWS) and Minimally Conscious State (MCS), is challenging. Even if a patient is unresponsive, he/she may be covertly aware in reason of a cognitive-motor dissociation, i.e., a preservation of cognitive functions despite a solely reflexive behavioral responsiveness. The approach of an external stimulus to the peripersonal space (PPS) modifies some biological measures (e.g., hand-blink reflex amplitude) to the purpose of defensive responses from threats. Such modulation depends on a top-down control of subcortical neural circuits, which can be explored through changes in cerebral blood flow velocity (CBFV), using functional transcranial Doppler (fTCD) and, thus, gaining useful, indirect information on brain connectivity. These data may be used for the DoC differential diagnosis. We evaluated the changes in CBFV by measuring the pulsatility index (PI) in 21 patients with DoC (10 patients with MCS and 11 with UWS) and 25 healthy controls (HC) during a passive movement and motor imagery (MI) task in which the hand of the subject approached and, then, moved away from the subject's face. In the passive movement task, the PI increased progressively in the HCs when the hand was moved toward the face and, then, it decreased when the hand was removed from the face. The PI increased when the hand was moved toward the face in patients with DoC, but then, it remained high when the hand was removed from the face and up to 30 s after the end of the movement in the patients with MCS (both MCS+ and MCS-) and 1 min in those with UWS, thus differentiating between patients with MCS and UWS. In the MI task, all the HCs, three out of four patients with MCS+, and one out of six patients with MCS- showed an increase-decrease PI change, whereas the remaining patients with MCS and all the patients with UWS showed no PI changes. Even though there is the possibility that our findings will not be replicated in all patients with DoC, we propose fTCD as a rapid and very easy tool to differentiate between patients with MCS and UWS, by identifying residual top-down modulation processes from higher order cortical areas to sensory-motor integration networks related to the PPS, when using passive movement tasks. PMID- 29459849 TI - Widely Used Commercial ELISA Does Not Detect Precursor of Haptoglobin2, but Recognizes Properdin as a Potential Second Member of the Zonulin Family. AB - Background: There is increasing evidence for the role of impaired intestinal permeability in obesity and associated metabolic diseases. Zonulin is an established serum marker for intestinal permeability and identical to pre haptoglobin2. Here, we aimed to investigate the relationship between circulating zonulin and metabolic traits related to obesity. Methods: Serum zonulin was measured by using a widely used commercial ELISA kit in 376 subjects from the metabolically well-characterized cohort of Sorbs from Germany. In addition, haptoglobin genotype was determined in DNA samples from all study subjects. Results: As zonulin concentrations did not correlate to the haptoglobin genotypes, we investigated the specificity of the zonulin ELISA assay using antibody capture experiments, mass spectrometry, and Western blot analysis. Using serum samples that gave the highest or lowest ELISA signals, we detected several proteins that are likely to be captured by the antibody in the present kit. However, none of these proteins corresponds to pre-haptoglobin2. We used increasing concentrations of recombinant pre-haptoglobin2 and complement C3 as one of the representative captured proteins and the ELISA kit did not detect either. Western blot analysis using both the polyclonal antibodies used in this kit and monoclonal antibodies rose against zonulin showed a similar protein recognition pattern but with different intensity of detection. The protein(s) measured using the ELISA kit was (were) significantly increased in patients with diabetes and obesity and correlated strongly with markers of the lipid and glucose metabolism. Combining mass spectrometry and Western blot analysis using the polyclonal antibodies used in the ELISA kit, we identified properdin as another member of the zonulin family. Conclusion: Our study suggests that the zonulin ELISA does not recognize pre-haptoglobin2, rather structural (and possibly functional) analog proteins belonging to the mannose-associated serine protease family, with properdin being the most likely possible candidate. PMID- 29459850 TI - Bacterial Seed Endophytes of Domesticated Cucurbits Antagonize Fungal and Oomycete Pathogens Including Powdery Mildew. AB - The cucurbit vegetables, including cucumbers, melons and pumpkins, have been cultivated for thousands of years without fungicides. However, their seed germination stage is prone to be infected by soil-borne fungal and oomycete pathogens. Endophytes are symbionts that reside inside plant tissues including seeds. Seed endophytes are founders of the juvenile plant microbiome and can promote host defense at seed germination and later stages. We previously isolated 169 bacterial endophytes associated with seeds of diverse cultivated cucurbits. We hypothesized that these endophytes can antagonize major fungal and oomycete pathogens. Here we tested the endophytes for in vitro antagonism (dual culture assays) against important soil-borne pathogens (Rhizoctonia solani, Fusarium graminearum, Phytophthora capsici, Pythium aphanideratum). The endophytes were also assayed in planta (leaf disk and detached leaf bioassays) for antagonism against a foliar pathogen of global importance, Podosphaera fuliginea, the causative agent of cucurbit powdery mildew. The endophytes were further tested in vitro for secretion of volatile organic compounds (VOCs) known to induce plant defense. Extracellular ribonuclease activity was also tested, as a subset of pathogenesis-related (PR) proteins of plant hosts implicated in suppression of fungal pathogens, displays ribonuclease activity. An unexpected majority of the endophytes (70%, 118/169) exhibited antagonism to the five phytopathogens, of which 68% (50/73) of in vitro antagonists belong to the genera Bacillus and Paenibacillus. All Lactococcus and Pantoea endophytes exhibited anti-oomycete activity. However, amongst the most effective inoculants against Podosphaera fuliginea were Pediococcus and Pantoea endophytes. Interestingly, 67% (113/169) of endophytes emitted host defense inducing VOCs (acetoin/diacetyl) and 62% (104/169) secreted extracellular ribonucleases in vitro, respectively. These results show that seeds of cultivated cucurbits package microbes with significant disease-suppression potential. As seeds can act as vectors for genetic transmission of endophytes across host generations, it is interesting to hypothesize whether humans, when selecting seeds of healthy hosts, may have inadvertently selected for disease-suppressing seed endophytes. As the majority of pathogen-suppressing endophytes belong to Bacillus and Paenibacillus, and since Bacilli are widely used as commercial biocontrol agents of vegetables, we propose that these agents are mimicking the ecological niche established by their endophytic cousins. PMID- 29459851 TI - Dynamics of Metabolite Induction in Fungal Co-cultures by Metabolomics at Both Volatile and Non-volatile Levels. AB - Fungal co-cultivation has emerged as a promising way for activating cryptic biosynthetic pathways and discovering novel antimicrobial metabolites. For the success of such studies, a key element remains the development of standardized co cultivation methods compatible with high-throughput analytical procedures. To efficiently highlight induction processes, it is crucial to acquire a holistic view of intermicrobial communication at the molecular level. To tackle this issue, a strategy was developed based on the miniaturization of fungal cultures that allows for a concomitant survey of induction phenomena in volatile and non volatile metabolomes. Fungi were directly grown in vials, and each sample was profiled by head space solid phase microextraction gas chromatography mass spectrometry (HS-SPME-GC-MS), while the corresponding solid culture medium was analyzed by liquid chromatography high resolution mass spectrometry (LC-HRMS) after solvent extraction. This strategy was implemented for the screening of volatile and non-volatile metabolite inductions in an ecologically relevant fungal co-culture of Eutypa lata (Pers.) Tul. & C. Tul. (Diatrypaceae) and Botryosphaeria obtusa (Schwein.) Shoemaker (Botryosphaeriaceae), two wood decaying fungi interacting in the context of esca disease of grapevine. For a comprehensive evaluation of the results, a multivariate data analysis combining Analysis of Variance and Partial Least Squares approaches, namely AMOPLS, was used to explore the complex LC-HRMS and GC-MS datasets and highlight dynamically induced compounds. A time-series study was carried out over 9 days, showing characteristic metabolite induction patterns in both volatile and non-volatile dimensions. Relevant links between the dynamics of expression of specific metabolite production were observed. In addition, the antifungal activity of 2 nonanone, a metabolite incrementally produced over time in the volatile fraction, was assessed against Eutypa lata and Botryosphaeria obtusa in an adapted bioassay set for volatile compounds. This compound has shown antifungal activity on both fungi and was found to be co-expressed with a known antifungal compound, O methylmellein, induced in solid media. This strategy could help elucidate microbial inter- and intra-species cross-talk at various levels. Moreover, it supports the study of concerted defense/communication mechanisms for efficiently identifying original antimicrobials. PMID- 29459852 TI - beta-HPV Infection Correlates with Early Stages of Carcinogenesis in Skin Tumors and Patient-Derived Xenografts from a Kidney Transplant Recipient Cohort. AB - Many malignancies that occur in high excess in kidney transplant recipients (KTRs) are due to viruses that thrive in the setting of immunosuppression. Keratinocyte carcinoma (KC), the most frequently occurring cancer type in KTR, has been associated with skin infection by human papillomavirus (HPV) from the beta genus. In this report, we extend our previous investigation aimed at identifying the presence of active beta-HPV infection in skin tumors from KTRs through detection of viral protein expression. Using a combination of antibodies raised against the E4 and L1 proteins of the beta-genotypes, we were able to visualize infection in five tumors [one keratoacanthoma (KA), three actinic keratoses (AKs), and one seborrheic keratoses (SKs)] that were all removed from two patients who had been both transplanted twice, had developed multiple KCs, and presented with a long history of immunosuppression (>30 years). These infected tissues displayed intraepidermal hyperplasia and increased expression of the DeltaNp63 protein, which extended into the upper epithelial layers. In addition, using a xenograft model system in nude mice displaying a humanized stromal bed in the site of grafting, we successfully engrafted three AKs, two of which were derived from the aforementioned KTRs and displayed beta-HPV infection in the original tumor. Of note, one AK-derived xenograft, along with its ensuing lymph node metastasis, was diagnosed as squamous cell carcinoma (SCC). In the latter, both beta-HPV infection and DeltaNp63 expression were no longer detectable. Although the overall success rate of engrafting was very low, the results of this study show for the first time that beta-HPV+ and DeltaNp63+ intraepidermal hyperplasia can indeed progress to an aggressive SCC able to metastasize. Consistent with a series of reports attributing a causative role of beta-HPV at early stages of skin carcinogenesis through DeltaNp63 induction and increased keratinocytes stemness, here we provide in vivo evidence that these events are also occurring in the affected skin of KTRs. Due to these beta-HPV driven molecular pathways, the nascent tumor cell is able to acquire a high enough number of carcinogenic insults that its proliferation and survival will eventually become independent of viral gene expression. PMID- 29459853 TI - Does Treatment Order Matter? Investigating the Ability of Bacteriophage to Augment Antibiotic Activity against Staphylococcus aureus Biofilms. AB - The inability to effectively treat biofilm-related infections is a major clinical challenge. This has been attributed to the heightened antibiotic tolerance conferred to bacterial cells embedded within biofilms. Lytic bacteriophages (phages) have evolved to effectively infect and eradicate biofilm-associated cells. The current study was designed to investigate the ability of phage treatment to enhance the activity of antibiotics against biofilm-forming Staphylococcus aureus. The biofilm positive S. aureus strain ATCC 35556, the lytic S. aureus phage SATA-8505, and five antibiotics (cefazolin, vancomycin, dicloxacillin, tetracycline, and linezolid), used to treat S. aureus infections, were tested in this study. The ability of the SATA-8505 phage to augment the effect of these antibiotics against biofilm-associated S. aureus cells was assessed by exposing them to one of the five following treatment strategies: (i) antibiotics alone, (ii) phage alone, (iii) a combination of the two treatments simultaneously, (iv) staggered exposure to the phage followed by antibiotics, and (v) staggered exposure to antibiotics followed by exposure to phage. The effect of each treatment strategy on biofilm cells was assessed by enumerating viable bacterial cells. The results demonstrate that the treatment of biofilms with either SATA-8505, antibiotics, or both simultaneously resulted in minimal reduction of viable biofilm-associated cells. However, a significant reduction [up to 3 log colony forming unit (CFU)/mL] was observed when the phage treatment preceded antibiotics. This effect was most pronounced with vancomycin and cefazolin which exhibited synergistic interactions with SATA-8505, particularly at lower antibiotic concentrations. This in vitro study provides proof of principle for the ability of phages to augment the activity of antibiotics against S. aureus biofilms. Our results also demonstrate that therapeutic outcomes can be influenced by the sequence in which these therapeutic agents are administered, and the nature of their interactions. Further investigation into the interactions between lytic phages and antibiotics against various biofilm forming organisms is important to direct future clinical translation of efficacious antibiotic-phage combination therapeutic strategies. PMID- 29459854 TI - The Glutaredoxin Gene, grxB, Affects Acid Tolerance, Surface Hydrophobicity, Auto Aggregation, and Biofilm Formation in Cronobacter sakazakii. AB - Cronobacter species are foodborne pathogens that can cause neonatal meningitis, necrotizing enterocolitis, and sepsis; they have unusual abilities to survive in environmental stresses such as acid stress. However, the factors involved in acid stress responses and biofilm formation in Cronobacter species are poorly understood. In this study, we investigated the role of grxB on cellular morphology, acid tolerance, surface hydrophobicity, auto-aggregation (AAg), motility, and biofilm formation in Cronobacter sakazakii. The deletion of grxB decreased resistance to acid stresses, and notably led to weaker surface hydrophobicity, AAg, and biofilm formation under normal and acid stress conditions, compared with those of the wild type strain; however, motility was unaffected. Therefore, grxB appears to contribute to the survival of C. sakazakii in acid stresses and biofilm formation. This is the first report to provide valuable evidence for the role of grxB in acid stress responses and biofilm formation in C. sakazakii. PMID- 29459855 TI - Severity of Systemic Inflammatory Response Syndrome Affects the Blood Levels of Circulating Inflammatory-Relevant MicroRNAs. AB - The systemic inflammatory response syndrome (SIRS) is a potentially lethal response triggered by diverse forms of tissue injury and infection. When systemic inflammation is triggered by infection, the term sepsis is used. Understanding how inflammation is mediated and regulated is of enormous medical importance. We previously demonstrated that circulating inflammatory-relevant microRNAs (CIR miRNAs) are candidate biomarkers for differentiating sepsis from SIRS. Here, we set out to determine how CIR-miRNA levels reflect SIRS severity and whether they derive from activated immune cells. Clinical disease severity scores and markers of red blood cell (RBC) damage or immune cell activation were correlated with CIR miRNA levels in patients with SIRS and sepsis. The release of CIR-miRNAs modulated during SIRS was assessed in immune cell cultures. We show that severity of non-infective SIRS, but not sepsis is reflected in the levels of miR-378a-3p, miR-30a-5p, miR-30d-5p, and miR-192-5p. These CIR-miRNA levels positively correlate with levels of the redox biomarker, peroxiredoxin-1 (Prdx-1), which has previously been shown to be released by immune cells during inflammation. Furthermore, in vitro activated immune cells produce SIRS-associated miR-378a-3p, miR-30a-5p, miR-30d-5p, and miR-192-5p. Our study furthers the understanding of the origin, role, and trafficking of CIR-miRNAs as potential regulators of inflammation. PMID- 29459856 TI - The Immune and Non-Immune Pathways That Drive Chronic Gastrointestinal Helminth Burdens in the Wild. AB - Parasitic helminths are extremely resilient in their ability to maintain chronic infection burdens despite (or maybe because of) their hosts' immune response. Explaining how parasites maintain these lifelong infections, identifying the protective immune mechanisms that regulate helminth infection burdens, and designing prophylactics and therapeutics that combat helminth infection, while preserving host health requires a far better understanding of how the immune system functions in natural habitats than we have at present. It is, therefore, necessary to complement mechanistic laboratory-based studies with studies on wild populations and their natural parasite communities. Unfortunately, the relative paucity of immunological tools for non-model species has held these types of studies back. Thankfully, recent progress in high-throughput 'omics platforms provide powerful and increasingly practical means for immunologists to move beyond traditional lab-based model organisms. Yet, assigning both metabolic and immune function to genes, transcripts, and proteins in novel species and assessing how they interact with other physiological and environmental factors requires identifying quantitative relationships between their expression and infection. Here, we used supervised machine learning to identify gene networks robustly associated with burdens of the gastrointestinal nematode Heligmosomoides polygyrus in its natural host, the wild wood mice Apodemus sylvaticus. Across 34 mice spanning two wild populations and across two different seasons, we found 17,639 transcripts that clustered in 131 weighted gene networks. These clusters robustly predicted H. polygyrus burden and included well-known effector and regulatory immune genes, but also revealed a number of genes associated with the maintenance of tissue homeostasis and hematopoiesis that have so far received little attention. We then tested the effect of experimentally reducing helminth burdens through drug treatment on those putatively protective immune factors. Despite the near elimination of H. polygyrus worms, the treatment had surprisingly little effect on gene expression. Taken together, these results suggest that hosts balance tissue homeostasis and protective immunity, resulting in relatively stable immune and, consequently, parasitological profiles. In the future, applying our approach to larger numbers of samples from additional populations will help further increase our ability to detect the immune pathways that determine chronic gastrointestinal helminth burdens in the wild. PMID- 29459857 TI - Genome-Wide Bimolecular Fluorescence Complementation-Based Proteomic Analysis of Toxoplasma gondii ROP18's Human Interactome Shows Its Key Role in Regulation of Cell Immunity and Apoptosis. AB - Toxoplasma gondii rhoptry protein ROP18 (TgROP18) is a key virulence factor secreted into the host cell during invasion, where it modulates the host cell response by interacting with its host targets. However, only a few TgROP18 targets have been identified. In this study, we applied a high-throughput protein protein interaction (PPI) screening in human cells using bimolecular fluorescence complementation (BiFC) to identify the targets of Type I strain ROP18 (ROP18I) and Type II strain ROP18 (ROP18II). From a pool of more than 18,000 human proteins, 492 and 141 proteins were identified as the targets of ROP18I and ROP18II, respectively. Gene ontology, search tool for the retrieval of interacting genes/proteins PPI network, and Ingenuity pathway analyses revealed that the majority of these proteins were associated with immune response and apoptosis. This indicates a key role of TgROP18 in manipulating host's immunity and cell apoptosis, which might contribute to the immune escape and successful parasitism of the parasite. Among the proteins identified, the immunity-related proteins N-myc and STAT interactor, IL20RB, IL21, ubiquitin C, and vimentin and the apoptosis-related protein P2RX1 were further verified as ROP18I targets by sensitized emission-fluorescence resonance energy transfer (SE-FRET) and co immunoprecipitation. Our study substantially contributes to the current limited knowledge on human targets of TgROP18 and provides a novel tool to investigate the function of parasite effectors in human cells. PMID- 29459858 TI - Type I Interferon Signaling Is Required for CpG-Oligodesoxynucleotide-Induced Control of Leishmania major, but Not for Spontaneous Cure of Subcutaneous Primary or Secondary L. major Infection. AB - We previously showed that in mice infected with Leishmania major type I interferons (IFNs) initiate the innate immune response to the parasite at day 1 and 2 of infection. Here, we investigated which type I IFN subtypes are expressed during the first 8 weeks of L. major infection and whether type I IFNs are essential for a protective immune response and clinical cure of the disease. In self-healing C57BL/6 mice infected with a high dose of L. major, IFN-alpha4, IFN alpha5, IFN-alpha11, IFN-alpha13, and IFN-beta mRNA were most prominently regulated during the course of infection. In C57BL/6 mice deficient for IFN-beta or the IFN-alpha/beta-receptor chain 1 (IFNAR1), development of skin lesions and parasite loads in skin, draining lymph node, and spleen was indistinguishable from wild-type (WT) mice. In line with the clinical findings, C57BL/6 IFN-beta-/ , IFNAR1-/-, and WT mice exhibited similar mRNA expression levels of IFN-gamma, interleukin (IL)-4, IL-12, IL-13, inducible nitric oxide synthase, and arginase 1 during the acute and late phase of the infection. Also, myeloid dendritic cells from WT and IFNAR1-/- mice produced comparable amounts of IL-12p40/p70 protein upon exposure to L. major in vitro. In non-healing BALB/c WT mice, the mRNAs of IFN-alpha subtypes (alpha2, alpha4, alpha5, alpha6, and alpha9) were rapidly induced after high-dose L. major infection. However, genetic deletion of IFNAR1 or IFN-beta did not alter the progressive course of infection seen in WT BALB/c mice. Finally, we tested whether type I IFNs and/or IL-12 are required for the prophylactic effect of CpG-oligodesoxynucleotides (ODN) in BALB/c mice. Local and systemic administration of CpG-ODN 1668 protected WT and IFN-beta-/- mice equally well from progressive leishmaniasis. By contrast, the protective effect of CpG ODN 1668 was lost in BALB/c IFNAR1-/- (despite a sustained suppression of IL-4) and in BALB/c IL-12p35-/- mice. From these data, we conclude that IFN-beta and IFNAR1 signaling are dispensable for a curative immune response to L. major in C57BL/6 mice and irrelevant for disease development in BALB/c mice, whereas IL-12 and IFN-alpha subtypes are essential for the disease prevention by CpG-ODNs in this mouse strain. PMID- 29459860 TI - Humoral Responses Elicited by Adenovirus Displaying Epitopes Are Induced Independently of the Infection Process and Shaped by the Toll-Like Receptor/MyD88 Pathway. AB - The use of serotype 5 adenovirus (Ad)-derived vectors in vaccination is confronted to preexisting anti-Ad immunity. Epitope display on Ad capsid is currently being investigated as an alternative approach of vaccination. The present study seeks to better understand virus- and host-related factors controlling the efficacy of this new vaccination approach. In contrast to an Ad vector expressing ovalbumin as a transgene, Ad displaying an ovalbumin-derived B cell epitope inserted into the fiber protein was able to elicit antibody responses in both Ad-naive and Ad-immune mice. Moreover, introduction of a set of mutations abrogating Ad interaction with its receptors did not modify the virus capacity to elicit a humoral response against the inserted epitope while reducing its capacity to mount antibody responses against the transgene product. Taken as a whole these data indicate that the efficacy of Ad displaying epitopes requires neither Ad binding to its receptors nor the infection process. In addition, the use of genetically deficient mice demonstrated that both toll-like receptor (TLR)/MyD88 and RIG-I/mitochondrial antiviral-signaling (MAVS) innate immunity pathways were dispensable to mount anti-epitope antibody responses. However, they also revealed that TLR/MyD88 pathway but not RIG-I/MAVS pathway controls the nature of antibodies directed against the displayed epitope. PMID- 29459859 TI - Next-Generation Vaccines Based on Bacille Calmette-Guerin. AB - Tuberculosis (TB), caused by the intracellular bacterium Mycobacterium tuberculosis (Mtb), remains a major health threat. A live, attenuated mycobacterium known as Bacille Calmette-Guerin (BCG), derived from the causative agent of cattle TB, Mycobacterium bovis, has been in clinical use as a vaccine for 90 years. The current incidence of TB demonstrates that BCG fails to protect sufficiently against pulmonary TB, the major disease manifestation and source of dissemination. The protective efficacy of BCG is on average 50% but varies substantially with geographical location and is poorer in those with previous exposure to mycobacteria. BCG can also cause adverse reactions in immunocompromised individuals. However, BCG has contributed to reduced infant TB mortality by protecting against extrapulmonary TB. In addition, BCG has been associated with reduced general childhood mortality by stimulating immune responses. In order to improve the efficacy of BCG, two major strategies have been employed. The first involves the development of recombinant live mycobacterial vaccines with improved efficacy and safety. The second strategy is to boost BCG with subunit vaccines containing Mtb antigens. This article reviews recombinant BCG strains that have been tested against TB in animal models. This includes BCG strains that have been engineered to induce increased immune responses by the insertion of genes for Mtb antigens, mammalian cytokines, or host resistance factors, the insertion of bacterial toxin-derived adjuvants, and the manipulation of bacterial genes in order to increase antigen presentation and immune activation. Subunit vaccines for boosting BCG are also briefly discussed. PMID- 29459861 TI - In-Depth Analysis of Human Neonatal and Adult IgM Antibody Repertoires. AB - Although high-throughput sequencing and associated bioinformatics technologies have enabled the in-depth, sequence-based characterization of human immune repertoires, only a few studies on a relatively small number of sequences explored the characteristics of antibody repertoires in neonates, with contradictory conclusions. To gain a more comprehensive understanding of the human IgM antibody repertoire, we performed Illumina sequencing and IMGT/HighV QUEST analysis of IgM heavy chain repertoire of the B lymphocytes from the cord blood (CB) of neonates, as well as the repertoire from peripheral blood of healthy human adults (HH). The comparative study revealed unexpectedly high levels of similarity between the neonatal and adult repertoires. In both repertoires, the VDJ gene usage showed no significant difference, and the most frequently used VDJ gene was IGHV4-59, IGHD3-10, and IGHJ3. The average amino acid (aa) length of CDR1 (CB: 8.5, HH: 8.4) and CDR2 (CB: 7.6, HH: 7.5), as well as the aa composition and the average hydrophobicity of the CDR3 demonstrated no significant difference between the two repertories. However, the average aa length of CDR3 was longer in the HH repertoire than the CB repertoire (CB: 14.5, HH: 15.5). Besides, the frequencies of aa mutations in CDR1 (CB: 19.33%, HH: 25.84%) and CDR2 (CB: 9.26%, HH: 17.82%) were higher in the HH repertoire compared to the CB repertoire. Interestingly, the most prominent difference between the two repertoires was the occurrence of N2 addition (CB: 64.87%, HH: 85.69%), a process that occurs during V-D-J recombination for introducing random nucleotide additions between D- and J-gene segments. The antibody repertoire of healthy adults was more diverse than that of neonates largely due to the higher occurrence of N2 addition. These findings may lead to a better understanding of antibody development and evolution pathways and may have potential practical value for facilitating the generation of more effective antibody therapeutics and vaccines.

AB - A number of excellent reviews on the potential of canine cancer immunotherapy are available, but many extrapolate from observations in humans when in fact only very few immunotherapies have been developed for canines that have shown efficacy in well-designed studies. Pharmaceutical and biotech companies are aware that the market for more expensive immunotherapies in canines is limited resulting in limited funding for clinical trials. However, dogs and other pets deserve access to this new form of cancer therapy. The purpose of this brief review is to summarize the current status of available immunotherapies for dogs and their near term prospects, provided we can effectively translate discoveries and progress in humans to canines. PMID- 29459863 TI - A Role for the Krebs Cycle Intermediate Citrate in Metabolic Reprogramming in Innate Immunity and Inflammation. AB - Metabolism in immune cells is no longer thought of as merely a process for adenosine triphosphate (ATP) production, biosynthesis, and catabolism. The reprogramming of metabolic pathways upon activation is also for the production of metabolites that can act as immune signaling molecules. Activated dendritic cells (DCs) and macrophages have an altered Krebs cycle, one consequence of which is the accumulation of both citrate and succinate. Citrate is exported from the mitochondria via the mitochondrial citrate- carrier. Cytosolic metabolism of citrate to acetyl-coenzyme A (acetyl-CoA) is important for both fatty-acid synthesis and protein acetylation, both of which have been linked to macrophage and DC activation. Citrate-derived itaconate has a direct antibacterial effect and also has been shown to act as an anti-inflammatory agent, inhibiting succinate dehydrogenase. These findings identify citrate as an important metabolite for macrophage and DC effector function.

AB - We recently demonstrated that lymph nodes (LNs) PD-1+/T follicular helper (Tfh) cells from antiretroviral therapy (ART)-treated HIV-infected individuals were enriched in cells containing replication competent virus. However, the distribution of cells containing inducible replication competent virus has been only partially elucidated in blood memory CD4 T-cell populations including the Tfh cell counterpart circulating in blood (cTfh). In this context, we have investigated the distribution of (1) total HIV-infected cells and (2) cells containing replication competent and infectious virus within various blood and LN memory CD4 T-cell populations of conventional antiretroviral therapy (cART) treated HIV-infected individuals. In the present study, we show that blood CXCR3 expressing memory CD4 T cells are enriched in cells containing inducible replication competent virus and contributed the most to the total pool of cells containing replication competent and infectious virus in blood. Interestingly, subsequent proviral sequence analysis did not indicate virus compartmentalization between blood and LN CD4 T-cell populations, suggesting dynamic interchanges between the two compartments. We then investigated whether the composition of blood HIV reservoir may reflect the polarization of LN CD4 T cells at the time of reservoir seeding and showed that LN PD-1+ CD4 T cells of viremic untreated HIV infected individuals expressed significantly higher levels of CXCR3 as compared to CCR4 and/or CCR6, suggesting that blood CXCR3-expressing CD4 T cells may originate from LN PD-1+ CD4 T cells. Taken together, these results indicate that blood CXCR3-expressing CD4 T cells represent the major blood compartment containing inducible replication competent virus in treated aviremic HIV-infected individuals. PMID- 29459865 TI - The Role of Mst1 in Lymphocyte Homeostasis and Function. AB - The Hippo pathway is an evolutionarily conserved pathway crucial for regulating tissue size and for limiting cancer development. However, recent work has also uncovered key roles for the mammalian Hippo kinases, Mst1/2, in driving appropriate immune responses by directing T cell migration, morphology, survival, differentiation, and activation. In this review, we discuss the classical signaling pathways orchestrated by the Hippo signaling pathway, and describe how Mst1/2 direct T cell function by mechanisms not seeming to involve the classical Hippo pathway. We also discuss why Mst1/2 might have different functions within organ systems and the immune system. Overall, understanding how Mst1/2 transmit signals to discrete biological processes in different cell types might allow for the development of better drug therapies for the treatments of cancers and immune related diseases. PMID- 29459866 TI - Current Status of Gene Engineering Cell Therapeutics. AB - Ex vivo manipulations of autologous patient's cells or gene-engineered cell therapeutics have allowed the development of cell and gene therapy approaches to treat otherwise incurable diseases. These modalities of personalized medicine have already shown great promises including product commercialization for some rare diseases. The transfer of a chimeric antigen receptor or T cell receptor genes into autologous T cells has led to very promising outcomes for some cancers, and particularly for hematological malignancies. In addition, gene engineered cell therapeutics are also being explored to induce tolerance and regulate inflammation. Here, we review the latest gene-engineered cell therapeutic approaches being currently explored to induce an efficient immune response against cancer cells or viruses by engineering T cells, natural killer cells, gamma delta T cells, or cytokine-induced killer cells and to modulate inflammation using regulatory T cells. PMID- 29459868 TI - Characteristics of Infection Immunity Regulated by Toxoplasma gondii to Maintain Chronic Infection in the Brain. AB - To examine the immune environment of chronic Toxoplasma gondii infection in the brain, the characteristics of infection-immunity (premunition) in infection with T. gondii strain ME49 were investigated for 12 weeks postinfection (PI). The results showed that neuronal cell death, microglia infiltration and activation, inflammatory and anti-inflammatory cytokine expression, Stat1 phosphorylation, and microglia activation and inflammatory gene transcripts related to M1 polarization in the brain were increased during the acute infection (AI) stage (within 6 weeks PI), suggesting that innate and cellular inflammatory response activation and neurodegeneration contributed to excessive inflammatory responses. However, these immune responses decreased during the chronic infection (CI) stage (over 6 weeks PI) with reductions in phosphorylated STAT1 (pSTAT1) and eosinophilic neurons. Notably, increases were observed in transcripts of T-cell exhaustion markers (TIM3, LAG3, KLRG1, etc.), suppressor of cytokines signaling 1 protein (SOCS1), inhibitory checkpoint molecules (PD-1 and PD-L1), and Arg1 from the AI stage (3 weeks PI), implying active immune intervention under the immune environment of M1 polarization of microglia and increases in inflammatory cytokine levels. However, when BV-2 microglia were stimulated with T. gondii lysate antigens (strain RH or ME49) in vitro, nitrite production increased and urea production decreased. Furthermore, when BV-2 cells were infected by T. gondii tachyzoites (strain RH or ME49) in vitro, nitric oxide synthase and COX-2 levels decreased, whereas Arg1 levels significantly increased. Moreover, Arg1 expression was higher in ME49 infection than in RH infection, whereas nitrite production was lower in ME49 infection than in RH infection. Accordingly, these results strongly suggest that immune triggering of T. gondii antigens induces M1 polarization and activation of microglia as well as increase NO production, whereas T. gondii infection induces the inhibition of harmful inflammatory responses, even with M1 polarization and activation of microglia and Th1 inflammatory responses, suggesting a host-parasite relationship through immune regulation during CI. This is a characteristic of infection immunity in infection with T. gondii in the central nervous system, and SOCS1, a negative regulator of toxoplasmic encephalitis, may play a role in the increase in Arg1 levels to suppress NO production. PMID- 29459869 TI - Fcu Receptor Promotes the Survival and Activation of Marginal Zone B Cells and Protects Mice against Bacterial Sepsis. AB - The marginal zone B cells (MZB) are located at the interface between the circulation and lymphoid tissue and as a gatekeeper play important roles in both innate and adaptive immune responses. We have previously found that MZB are significantly reduced in mice deficient in the IgM Fc receptor (FcMUR) but how FcMUR regulates the development and function of MZB remains unknown. In this study, we found that both marginal zone precursor (MZP) and MZB were decreased in FcMUR-/- mice. The reduction of MZP and MZB was not due to impaired proliferation of these cells but rather due to their increased death. Further analysis revealed that FcMUR-/- MZB had reduced tonic BCR signal, as evidenced by their decreased levels of phosphorylated SYK and AKT relative to WT MZB. MZB in FcMUR-/- mice responded poorly to LPS in vivo when compared with MZB in WT mice. Consistent with the reduced proportion of MZB and their impaired response to LPS, antibody production against the type 1 T-independent Ag, NP-LPS, was significantly reduced in FcMUR-/- mice. Moreover, FcMUR-/- mice were highly susceptible to Citrobacter rodentium-induced sepsis. These results reveal a critical role for FcMUR in the survival and activation of MZB and in protection against acute bacterial infection. PMID- 29459867 TI - The Multirole of Liposomes in Therapy and Prevention of Infectious Diseases. AB - Liposomes are closed bilayer structures spontaneously formed by hydrated phospholipids that are widely used as efficient delivery systems for drugs or antigens, due to their capability to encapsulate bioactive hydrophilic, amphipathic, and lipophilic molecules into inner water phase or within lipid leaflets. The efficacy of liposomes as drug or antigen carriers has been improved in the last years to ameliorate pharmacokinetics and capacity to release their cargo in selected target organs or cells. Moreover, different formulations and variations in liposome composition have been often proposed to include immunostimulatory molecules, ligands for specific receptors, or stimuli responsive compounds. Intriguingly, independent research has unveiled the capacity of several phospholipids to play critical roles as intracellular messengers in modulating both innate and adaptive immune responses through various mechanisms, including (i) activation of different antimicrobial enzymatic pathways, (ii) driving the fusion-fission events between endosomes with direct consequences to phagosome maturation and/or to antigen presentation pathway, and (iii) modulation of the inflammatory response. These features can be exploited by including selected bioactive phospholipids in the bilayer scaffold of liposomes. This would represent an important step forward since drug or antigen carrying liposomes could be engineered to simultaneously activate different signal transduction pathways and target specific cells or tissues to induce antigen specific T and/or B cell response. This lipid-based host-directed strategy can provide a focused antimicrobial innate and adaptive immune response against specific pathogens and offer a novel prophylactic or therapeutic option against chronic, recurrent, or drug-resistant infections. PMID- 29459870 TI - Is the A-Chain the Engine That Drives the Diversity of C1q Functions? Revisiting Its Unique Structure. AB - The immunopathological functions associated with human C1q are still growing in terms of novelty, diversity, and pathologic relevance. It is, therefore, not surprising that C1q is being recognized as an important molecular bridge between innate and adaptive immunity. The secret of this functional diversity, in turn, resides in the elegant but complex structure of the C1q molecule, which is assembled from three distinct gene products: A, B, and C, each of which has evolved from a separate and unique ancestral gene template. The C1q molecule is made up of 6A, 6B, and 6C polypeptide chains, which are held together through strong covalent and non-covalent bonds to form the 18-chain, bouquet-of-flower like protein that we know today. The assembled C1q protein displays at least two distinct structural and functional regions: the collagen-like region (cC1q) and the globular head region (gC1q), each being capable of driving a diverse range of ligand- or receptor-mediated biological functions. What is most intriguing, however, is the observation that most of the functions appear to be predominantly driven by the A-chain of the molecule, which begs the question: what are the evolutionary modifications or rearrangements that singularly shaped the primordial A-chain gene to become a pluripotent and versatile component of the intact C1q molecule? Here, we revisit and discuss some of the known unique structural and functional features of the A-chain, which may have contributed to its versatility. PMID- 29459871 TI - Staphylococcal Protein A Is a Key Factor in Neutrophil Extracellular Traps Formation. AB - Staphylococcus aureus are strong inducers of neutrophil extracellular traps (NETs), a defense mechanism of neutrophils against pathogens. Our aim was to explore the role of Protein A in S. aureus-induced NETosis. We determined the Protein A production of four different S. aureus strains and found a direct relationship between the degree of NETosis induction and Protein A production: strains producing higher concentrations of Protein A evoke significantly more NETs. A S. aureus strain in which Protein A as well as a second binding protein for immunoglobulins (Sbi) have been knocked-out (DeltaSpA DeltaSbi) induced significantly less NETosis than the wild-type strain. NETosis induction by this knockout strain can be rescued by the addition of purified Protein A. Dead S. aureus did not induce NETosis. In conclusion, Protein A is a determinant for NETosis induction by S. aureus. PMID- 29459872 TI - The Neurokinin-1 Receptor Contributes to the Early Phase of Lipopolysaccharide Induced Fever via Stimulation of Peripheral Cyclooxygenase-2 Protein Expression in Mice. AB - Neurokinin (NK) signaling is involved in various inflammatory processes. A common manifestation of systemic inflammation is fever, which is usually induced in animal models with the administration of bacterial lipopolysaccharide (LPS). A role for the NK1 receptor was shown in LPS-induced fever, but the underlying mechanisms of how the NK1 receptor contributes to febrile response, especially in the early phase, have remained unknown. We administered LPS (120 ug/kg, intraperitoneally) to mice with the Tacr1 gene, i.e., the gene encoding the NK1 receptor, either present (Tacr1+/+ ) or absent (Tacr1-/- ) and measured their thermoregulatory responses, serum cytokine levels, tissue cyclooxygenase-2 (COX 2) expression, and prostaglandin (PG) E2 concentration. We found that the LPS induced febrile response was attenuated in Tacr1-/- compared to their Tacr1+/+ littermates starting from 40 min postinfusion. The febrigenic effect of intracerebroventricularly administered PGE2 was not suppressed in the Tacr1-/- mice. Serum concentration of pyrogenic cytokines did not differ between Tacr1-/- and Tacr1+/+ at 40 min post-LPS infusion. Administration of LPS resulted in amplification of COX-2 mRNA expression in the lungs, liver, and brain of the mice, which was statistically indistinguishable between the genotypes. In contrast, the LPS-induced augmentation of COX-2 protein expression was attenuated in the lungs and tended to be suppressed in the liver of Tacr1-/- mice compared with Tacr1+/+ mice. The Tacr1+/+ mice responded to LPS with a significant surge of PGE2 production in the lungs, whereas Tacr1-/- mice did not. In conclusion, the NK1 receptor is necessary for normal fever genesis. Our results suggest that the NK1 receptor contributes to the early phase of LPS-induced fever by enhancing COX-2 protein expression in the periphery. These findings advance the understanding of the crosstalk between NK signaling and the "cytokine-COX-2 prostaglandin E2" axis in systemic inflammation, thereby open up the possibilities for new therapeutic approaches. PMID- 29459873 TI - Integrase Defective Lentiviral Vector as a Vaccine Platform for Delivering Influenza Antigens. AB - Viral vectors represent an attractive technology for vaccine delivery. We exploited the integrase defective lentiviral vector (IDLV) as a platform for delivering relevant antigens within the context of the ADITEC collaborative research program. In particular, Influenza virus hemagglutinin (HA) and nucleoprotein (NP) were delivered by IDLVs while H1N1 A/California/7/2009 subunit vaccine (HAp) with or without adjuvant was used to compare the immune response in a murine model of immunization. In order to maximize the antibody response against HA, both IDLVs were also pseudotyped with HA (IDLV-HA/HA and IDLV-NP/HA, respectively). Groups of CB6F1 mice were immunized intramuscularly with a single dose of IDLV-NP/HA, IDLV-HA/HA, HAp alone, or with HAp together with the systemic adjuvant MF59. Six months after the vaccine prime all groups were boosted with HAp alone. Cellular and antibody responses to influenza antigens were measured at different time points after the immunizations. Mice immunized with HA-pseudotyped IDLVs showed similar levels of anti-H1N1 IgG over time, evaluated by ELISA, which were comparable to those induced by HAp + MF59 vaccination, but significantly higher than those induced by HAp alone. The boost with HAp alone induced an increase of antibodies in all groups, and the responses were maintained at higher levels up to 18 weeks post-boost. The antibody response was functional and persistent overtime, capable of neutralizing virus infectivity, as evaluated by hemagglutination inhibition and microneutralization assays. Moreover, since neuraminidase (NA)-expressing plasmid was included during IDLV preparation, immunization with IDLV-NP/HA and IDLV-HA/HA also induced functional anti-NA antibodies, evaluated by enzyme-linked lectin assay. IFNgamma-ELISPOT showed evidence of HA-specific response in IDLV-HA/HA immunized animals and persistent NP-specific CD8+ T cell response in IDLV-NP/HA immunized mice. Taken together our results indicate that IDLV can be harnessed for producing a vaccine able to induce a comprehensive immune response, including functional antibodies directed toward HA and NA proteins present on the vector particles in addition to a functional T cell response directed to the protein transcribed from the vector. PMID- 29459875 TI - Decrease in the Photosynthetic Performance of Temperate Grassland Species Does Not Lead to a Decline in the Gross Primary Production of the Ecosystem. AB - Plants, under stressful conditions, can proceed to photosynthetic adjustments in order to acclimatize and alleviate the detrimental impacts on the photosynthetic apparatus. However, it is currently unclear how adjustment of photosynthetic processes under environmental constraints by plants influences CO2 gas exchange at the ecosystem-scale. Over a 2-year period, photosynthetic performance of a temperate grassland ecosystem was characterized by conducting frequent chlorophyll fluorescence (ChlF) measurements on three primary grassland species (Lolium perenne L., Taraxacum sp., and Trifolium repens L.). Ecosystem photosynthetic performance was estimated from measurements performed on the three dominant grassland species weighed based on their relative abundance. In addition, monitoring CO2 fluxes was performed by eddy covariance. The highest decrease in photosynthetic performance was detected in summer, when environmental constraints were combined. Dicot species (Taraxacum sp. and T. repens) presented the strongest capacity to up-regulate PSI and exhibited the highest electron transport efficiency under stressful environmental conditions compared with L. perenne. The decline in ecosystem photosynthetic performance did not lead to a reduction in gross primary productivity, likely because increased light energy was available under these conditions. The carbon amounts fixed at light saturation were not influenced by alterations in photosynthetic processes, suggesting photosynthesis was not impaired. Decreased photosynthetic performance was associated with high respiration flux, but both were influenced by temperature. Our study revealed variation in photosynthetic performance of a grassland ecosystem responded to environmental constraints, but alterations in photosynthetic processes appeared to exhibit a negligible influence on ecosystem CO2 fluxes. PMID- 29459876 TI - Mapping Late Leaf Spot Resistance in Peanut (Arachis hypogaea) Using QTL-seq Reveals Markers for Marker-Assisted Selection. AB - Late leaf spot (LLS; Cercosporidium personatum) is a major fungal disease of cultivated peanut (Arachis hypogaea). A recombinant inbred line population segregating for quantitative field resistance was used to identify quantitative trait loci (QTL) using QTL-seq. High rates of false positive SNP calls using established methods in this allotetraploid crop obscured significant QTLs. To resolve this problem, robust parental SNPs were first identified using polyploid specific SNP identification pipelines, leading to discovery of significant QTLs for LLS resistance. These QTLs were confirmed over 4 years of field data. Selection with markers linked to these QTLs resulted in a significant increase in resistance, showing that these markers can be immediately applied in breeding programs. This study demonstrates that QTL-seq can be used to rapidly identify QTLs controlling highly quantitative traits in polyploid crops with complex genomes. Markers identified can then be deployed in breeding programs, increasing the efficiency of selection using molecular tools. Key Message: Field resistance to late leaf spot is a quantitative trait controlled by many QTLs. Using polyploid-specific methods, QTL-seq is faster and more cost effective than QTL mapping. PMID- 29459874 TI - Traversing the Links between Heavy Metal Stress and Plant Signaling. AB - Plants confront multifarious environmental stresses widely divided into abiotic and biotic stresses, of which heavy metal stress represents one of the most damaging abiotic stresses. Heavy metals cause toxicity by targeting crucial molecules and vital processes in the plant cell. One of the approaches by which heavy metals act in plants is by over production of reactive oxygen species (ROS) either directly or indirectly. Plants act against such overdose of metal in the environment by boosting the defense responses like metal chelation, sequestration into vacuole, regulation of metal intake by transporters, and intensification of antioxidative mechanisms. This response shown by plants is the result of intricate signaling networks functioning in the cell in order to transmit the extracellular stimuli into an intracellular response. The crucial signaling components involved are calcium signaling, hormone signaling, and mitogen activated protein kinase (MAPK) signaling that are discussed in this review. Apart from signaling components other regulators like microRNAs and transcription factors also have a major contribution in regulating heavy metal stress. This review demonstrates the key role of MAPKs in synchronously controlling the other signaling components and regulators in metal stress. Further, attempts have been made to focus on metal transporters and chelators that are regulated by MAPK signaling. PMID- 29459877 TI - Simultaneous Transfer of Leaf Rust and Powdery Mildew Resistance Genes from Hexaploid Triticale Cultivar Sorento into Bread Wheat. AB - Wheat powdery mildew, caused by Blumeria graminis f. sp. tritici, and wheat leaf rust, caused by Puccinia triticina Eriks, are two important diseases that severely threaten wheat production. Sorento, a hexaploid triticale cultivar from Poland, shows high resistance to the wheat powdery mildew isolate E09 and the leaf rust isolate PHT in Beijing, China. To introduce resistance genes into common wheat, Sorento was crossed with wheat line Xuezao, which is susceptible to both diseases, and the F1 hybrids were then backcrossed with Xuezao as the recurrent male parent. By marker analysis, we demonstrate that the long arm of the 2R (2RL) chromosome confers resistance to both the leaf rust and powdery mildew isolates at adult-plant and seedling stages, while the long arm of 4R (4RL) confers resistance only to powdery mildew at both stages. The chromosomal composition of BC2F3 plants containing 2R or 2RL and 4R or 4RL in the form of substitution and translocation were confirmed by GISH (genomic in situ hybridization) and FISH (fluorescence in situ hybridization). Monosomic and disomic substitutions of a wheat chromosome with chromosome 2R or 4R, as well as one 4RS-4DL/4DS-4RL reciprocal translocation homozigote and one 2RL-1DL translocation hemizigote, were recovered. Such germplasms are of great value in wheat improvement. PMID- 29459878 TI - Bemisia tabaci MED Population Density as Affected by Rootstock-Modified Leaf Anatomy and Amino Acid Profiles in Hydroponically Grown Tomato. AB - Bemisia tabaci is one of the most devastating pests in tomato greenhouse production. Insecticide resistance management for B. tabaci requires a novel approach that maximizes non-chemical methods for pest control. The aim of this study was to test the effects of rootstocks on B. tabaci populations in hydroponically grown tomato plants. In order to contribute to the better understanding of the mechanisms defining the attractiveness of plant to the aerial pest, the effects of rootstocks on leaf anatomy and the amino acid composition of phloem sap were assessed. A two-factorial experimental design was adopted using cultivars (rootstock cultivars and Clarabella) grown as either non grafted or grafted with cultivar Clarabella as a scion. The rootstock cultivars included Arnold, Buffon, Emperador, and Maxifort. A reduction in B. tabaci density was observed using all rootstock cultivars. The number of adult individuals per leaf was 2.7-5.4 times lower on rootstock cultivars than on Clarabella. The number of large nymphs per square centimeter was at least 24% higher on non-grafted Clarabella compared with all other treatments. The leaf lamina thickness and mesophyll thickness were lower in self-grafted Clarabella than in non-grafted or in one grafted on rootstock cultivars; however, the extent of this reduction depended on the rootstock. The leaves with thinner laminae were generally less attractive to B. tabaci. Eighteen amino acids were detected in the exudates of phloem sap. In all treatments, the most abundant amino acid was gamma aminobutyric acid (GABA), followed by proline, serine, alanine, and histidine. The scion cultivar Clarabella was the most attractive to B. tabaci and had a higher content of leucine than did rootstock cultivars, and a higher content of lysine compared to Buffon and Maxifort. The features modified by rootstock such are changes in leaf anatomy can affect the attractiveness of plants to B. tabaci. Thus, the grafting of tomato could constitute a valuable tool in an integrated management strategy against this aerial pest. PMID- 29459879 TI - Cold-Induced Male Meiotic Restitution in Arabidopsis thaliana Is Not Mediated by GA-DELLA Signaling. AB - Short periods of cold stress induce male meiotic restitution and diploid pollen formation in Arabidopsis thaliana by specifically interfering with male meiotic cytokinesis. Similar alterations in male meiotic cell division and gametophytic ploidy stability occur when gibberellic acid (GA) signaling is perturbed in developing anthers. In this study, we found that exogenous application of GA primarily induces second division restitution (SDR)-type pollen in Arabidopsis, similar to what cold does. Driven by the close similarity in cellular defects, we tested the hypothesis that cold-induced meiotic restitution is mediated by GA DELLA signaling. Using a combination of chemical, genetic and cytological approaches, however, we found that both exogenously and endogenously altered GA signaling do not affect the cold sensitivity of male meiotic cytokinesis. Moreover, in vivo localization study using a GFP-tagged version of RGA protein revealed that cold does not affect the expression pattern and abundance of DELLA in Arabidopsis anthers at tetrad stage. Expression study found that transcript of RGA appears enhanced in cold-stressed young flower buds. Since our previous work demonstrated that loss of function of DELLA causes irregular male meiotic cytokinesis, we here conclude that cold-induced meiotic restitution is not mediated by DELLA-dependent GA signaling. PMID- 29459881 TI - Fatty Acid and Associated Gene Expression Analyses of Three Tree Peony Species Reveal Key Genes for alpha-Linolenic Acid Synthesis in Seeds. AB - The increasing demand for healthy edible oil has generated the need to identify promising oil crops. Tree peony (Paeonia section Moutan DC.) is a woody oil crop with alpha-linolenic acid (ALA) contributing for 45% of the total fatty acid (FA) content in seeds. Molecular and genetic differences that contribute to varied FA content and composition among the wild peony species are, however, poorly understood. Analyses of FA content and composition during seed development in three tree peony species (Paeonia rockii, P. potaninii, and P. lutea) showed varied FA content among them with highest in P. rockii, followed by P. potaninii, and P. lutea. Total FA content among these species increased with seed development and reached its maximum in its final stage. Seed FA composition analysis of the three species also revealed that ALA (C18:3) was the most abundant, followed by oleic (C18:1) and linoleic (C18:2) acids. Additionally, quantitative real-time RT-PCR analyses of 10 key seed oil synthesis genes in the three tree peony species revealed that FAD3, FAD2, beta-PDHC, LPAAT, and Oleosin gene expression levels positively correlate with total FA content and rate of accumulation. Specifically, the abundance of FAD3 transcripts in P. rockii compared with P. potaninii, and P. lutea suggests that FAD3 might play an important role in synthesis of ALA via phosphatidylcholine-derived pathway. Overall, comparative analyses of FA content and composition in three different peony species revealed a correlation between efficient lipid accumulation and lipid gene expression during seed development. Further characterization and metabolic engineering of these key genes from peonies will allow for subsequent improvement of tree peony oil quality and production. PMID- 29459880 TI - Molecular Phylogeny and Dating of Forsythieae (Oleaceae) Provide Insight into the Miocene History of Eurasian Temperate Shrubs. AB - Tribe Forsythieae (Oleaceae), containing two genera (Abeliophyllum and Forsythia) and 13 species, is economically important plants used as ornamentals and in traditional medicine. This tribe species occur primarily in mountainous regions of Eurasia with the highest species diversity in East Asia. Here, we examine 11 complete chloroplast genome and nuclear cycloidea2 (cyc2) DNA sequences of 10 Forsythia species and Abeliophyllum distichum using Illumina platform to provide the phylogeny and biogeographic history of the tribe. The chloroplast genomes of the 11 Forsythieae species are highly conserved, except for a deletion of about 400 bp in the accD-psaI region detected only in Abeliophyllum. Within Forsythieae species, analysis of repetitive sequences revealed a total of 51 repeats comprising 26 forward repeats, 22 palindromic repeats, and 3 reverse repeats. Of those, 19 repeats were common and 32 were unique to one or more Forsythieae species. Our phylogenetic analyses supported the monophyly of Forsythia and its sister group is Abeliophyllum using the concatenated dataset of 78 chloroplast genes. Within Forsythia, Forsythia likiangensis and F. giraldiana were basal lineages followed by F. europaea; the three species are characterized by minutely serrate or entire leaf margins. The remaining species, which are distributed in East Asia, formed two major clades. One clade included F. ovata, F. velutina, and F. japonica; they are morphologically supported by broadly ovate leaves. Another clade of F. suspensa, F. saxatilis, F. viridissima, and F. koreana characterized by lanceolate leaves (except F. suspensa which have broad ovate leaves). Although cyc2 phylogeny is largely congruent to chloroplast genome phylogeny, we find the discordance between two phylogenies in the position of F. ovata suggesting that introgression of the chloroplast genome from one species into the nuclear background of another by interspecific hybridization in East Asian Forsythia species. Molecular dating and biogeographic reconstructions suggest an origin of the Forsythieae species in East China in the Miocene. Distribution patterns in Forsythia indicated that the species were radially differentiated from East China, and the speciation of the European F. europaea was the result of both vicariance and dispersal in the late Miocene to Pliocene. PMID- 29459882 TI - Identification of a New Mullet Species Complex Based on an Integrative Molecular and Cytogenetic Investigation of Mugil hospes (Mugilidae: Mugiliformes). AB - Mullets are very common fishes included in the family Mugilidae, (Mugiliformes), which are characterized by both a remarkably uniform external morphology and internal anatomy. Recently, within this family, different species complexes were molecularly identified within Mugil, a genus which is characterized by lineages that sometimes show very different karyotypes. Here we report the results of cytogenetic and molecular analyses conducted on Mugil hospes, commonly known as the hospe mullet, from Ecuador. The study aims to verify whether the original described species from the Pacific Ocean corresponds to that identified in the Atlantic Ocean, and to identify species-specific chromosome markers that can add new comparative data about Mugilidae karyotype evolution. The karyotype of M. hospes from Ecuador is composed of 48 acrocentric chromosomes and shows two active nucleolar organizer regions (NORs). In situ hybridization, using different types of repetitive sequences (rDNAs, U1 snDNA, telomeric repeats) as probes, identified species-specific chromosome markers that have been compared with those of other species of the genus Mugil. Cytochrome c oxidase subunit I (COI) sequence analysis shows only 92-93% similarity with sequences previously deposited under this species name in GenBank, all of which were from the Atlantic Ocean. Phylogenetic reconstructions indicate the presence of three well-supported hospe mullet lineages whose molecular divergence is compatible with the presence of distinct species. Indeed, the first lineage includes samples from Ecuador, whereas the other two lineages include the Atlantic samples and correspond to M. brevirostris from Brazil and Mugil sp. R from Belize/Venezuela. Results here provided reiterate the pivotal importance of an integrative molecular and cytogenetic approach in the reconstruction of the relationships within Mugilidae. PMID- 29459884 TI - Ecological Networks and Urban Crime: The Structure of Shared Routine Activity Locations and Neighborhood-Level Informal Control Capacity. AB - Drawing on Jacobs (1961), we hypothesize that public contact among neighborhood residents while engaged in day-to-day routines, captured by the aggregate network structure of shared local exposure, is consequential for crime. Neighborhoods in which residents come into contact more extensively in the course of conventional routines will exhibit higher levels of public familiarity, trust, and collective efficacy with implications for the informal social control of crime. We employ the concept of ecological ("eco-") networks - networks linking households within neighborhoods through shared activity locations - to formalize the notion of overlapping routines. Using micro-simulations of household travel patterns to construct census tract-level eco-networks for Columbus, OH, we examine the hypothesis that eco-network intensity (the probability that households tied through one location in a neighborhood eco-network will also be tied through another visited location) is negatively associated with tract-level crime rates (N=192). Fitted spatial autoregressive models offer evidence that neighborhoods with higher intensity eco-networks exhibit lower levels of violent and property crime. In contrast, a higher prevalence of non-resident visitors to a given tract is positively associated with property crime. These analyses hold the potential to enrich insight into the ecological processes that shape variation in neighborhood crime.

AB - Mammalian olfaction depends on chemosensory neurons of the main olfactory epithelia (MOE), and/or of the accessory olfactory epithelia in the vomeronasal organ (VNO). Thus, we have generated the VNO and MOE transcriptomes and the nasal cavity proteome of the house mouse, Mus musculus musculus. Both transcriptomes had low levels of sexual dimorphisms, while the soluble proteome of the nasal cavity revealed high levels of sexual dimorphism similar to that previously reported in tears and saliva. Due to low levels of sexual dimorphism in the olfactory receptors in MOE and VNO, the sex-specific sensing seems less likely to be dependent on receptor repertoires. However, olfaction may also depend on a continuous removal of background compounds from the sites of detection. Odorant binding proteins (OBPs) are thought to be involved in this process and in our study Obp transcripts were most expressed along other lipocalins (e.g., Lcn13, Lcn14) and antimicrobial proteins. At the level of proteome, OBPs were highly abundant with only few being sexually dimorphic. We have, however, detected the major urinary proteins MUP4 and MUP5 in males and females and the male-biased central/group-B MUPs that were thought to be abundant mainly in the urine. The exocrine gland-secreted peptides ESP1 and ESP22 were male-biased but not male specific in the nose. For the first time, we demonstrate that the expression of nasal lipocalins correlates with antimicrobial proteins thus suggesting that their individual variation may be linked to evolvable mechanisms that regulate natural microbiota and pathogens that regularly enter the body along the 'eyes nose-oral cavity' axis. PMID- 29459885 TI - Platelet-Activating Factor Receptor Ligands Protect Tumor Cells from Radiation Induced Cell Death. AB - Irradiation generates oxidized phospholipids that activate platelet-activating factor receptor (PAFR) associated with pro-tumorigenic effects. Here, we investigated the involvement of PAFR in tumor cell survival after irradiation. Cervical cancer samples presented higher levels of PAF-receptor gene (PTAFR) when compared with normal cervical tissue. In cervical cancer patients submitted to radiotherapy (RT), the expression of PTAFR was significantly increased. Cervical cancer-derived cell lines (C33, SiHa, and HeLa) and squamous carcinoma cell lines (SCC90 and SCC78) express higher levels of PAFR mRNA and protein than immortalized keratinocytes. Gamma radiation increased PAFR expression and induced PAFR ligands and prostaglandin E2 (PGE2) in these tumor cells. The blocking of PAFR with the antagonist CV3938 before irradiation inhibited PGE2 and increased tumor cells death. Similarly, human carcinoma cells transfected with PAFR (KBP) were more resistant to radiation compared to those lacking the receptor (KBM). PGE2 production by irradiated KBP cells was also inhibited by CV3988. These results show that irradiation of carcinoma cells generates PAFR ligands that protect tumor cells from death and suggests that the combination of RT with a PAFR antagonist could be a promising strategy for cancer treatment. PMID- 29459886 TI - DNA Damage, Repair, and Cancer Metabolism. AB - Although there has been a renewed interest in the field of cancer metabolism in the last decade, the link between metabolism and DNA damage/DNA repair in cancer has yet to be appreciably explored. In this review, we examine the evidence connecting DNA damage and repair mechanisms with cell metabolism through three principal links. (1) Regulation of methyl- and acetyl-group donors through different metabolic pathways can impact DNA folding and remodeling, an essential part of accurate double strand break repair. (2) Glutamine, aspartate, and other nutrients are essential for de novo nucleotide synthesis, which dictates the availability of the nucleotide pool, and thereby influences DNA repair and replication. (3) Reactive oxygen species, which can increase oxidative DNA damage and hence the load of the DNA-repair machinery, are regulated through different metabolic pathways. Interestingly, while metabolism affects DNA repair, DNA damage can also induce metabolic rewiring. Activation of the DNA damage response (DDR) triggers an increase in nucleotide synthesis and anabolic glucose metabolism, while also reducing glutamine anaplerosis. Furthermore, mutations in genes involved in the DDR and DNA repair also lead to metabolic rewiring. Links between cancer metabolism and DNA damage/DNA repair are increasingly apparent, yielding opportunities to investigate the mechanistic basis behind potential metabolic vulnerabilities of a substantial fraction of tumors. PMID- 29459887 TI - Role of BRCA Mutations in the Modulation of Response to Platinum Therapy. AB - Recent years have seen cancer emerge as one of the leading cause of mortality worldwide with breast cancer being the second most common cause of death among women. Individuals harboring BRCA mutations are at a higher risk of developing breast and/or ovarian cancers. This risk is much greater in the presence of germline mutations. BRCA1 and BRCA2 play crucial role in the DNA damage response and repair pathway, a function that is critical in preserving the integrity of the genome. Mutations that interfere with normal cellular function of BRCA not only lead to onset and progression of cancer but also modulate therapy outcome of treatment with platinum drugs. In this review, we discuss the structural and functional impact of some of the prevalent BRCA mutations in breast and ovarian cancers and their role in platinum therapy response. Understanding the response of platinum drugs in the context of BRCA mutations may contribute toward developing better therapeutics that can improve survival and quality of life of patients. PMID- 29459888 TI - Genetic Separation of Listeria monocytogenes Causing Central Nervous System Infections in Animals. AB - Listeria monocytogenes is a foodborne pathogen that causes abortion, septicemia, gastroenteritis and central nervous system (CNS) infections in ruminants and humans. L. monocytogenes strains mainly belong to two distinct phylogenetic groups, named lineages I and II. In general, clinical cases in humans and animals, in particular CNS infections, are caused by lineage I strains, while most of the environmental and food strains belong to lineage II. Little is known about why lineage I is more virulent than lineage II, even though various molecular factors and mechanisms associated with pathogenesis are known. In this study, we have used a variety of whole genome sequence analyses and comparative genomic tools in order to find characteristics that distinguish lineage I from lineage II strains and CNS infection strains from non-CNS strains. We analyzed 225 strains and identified single nucleotide variants between lineages I and II, as well as differences in the gene content. Using a novel approach based on Reads Per Kilobase per Million Mapped (RPKM), we identified 167 genes predominantly absent in lineage II but present in lineage I. These genes are mostly encoding for membrane-associated proteins. Additionally, we found 77 genes that are largely absent in the non-CNS associated strains, while 39 genes are especially lacking in our defined "non-clinical" group. Based on the RPKM analysis and the metadata linked to the L. monocytogenes strains, we identified 6 genes potentially associated with CNS cases, which include a transcriptional regulator, an ABC transporter and a non-coding RNA. Although there is not a clear separation between pathogenic and non-pathogenic strains based on phylogenetic lineages, the presence of the genes identified in our study reveals potential pathogenesis traits in ruminant L. monocytogenes strains. Ultimately, the differences that we have found in our study will help steer future studies in understanding the virulence mechanisms of the most pathogenic L. monocytogenes strains. PMID- 29459889 TI - Case Report: A Child with Gross Hematuria and the Importance of Travel History. AB - We report a case of a 5-year-old girl who presented with a 3-month-long history of gross hematuria. She underwent an extensive laboratory workup (including an automated urine microscopy) and a kidney biopsy, all of which were within normal limits. While being prepared for a cystoscopy and more advanced imaging of the urinary tract, the family mentioned history of travel to a schistosomiasis endemic area prompting a more thorough ova and parasite examination of the urine. Urine microscopy confirmed the diagnosis of Schistosoma hematobium. PMID- 29459890 TI - Promoting Local Ownership: Lessons Learned from Process of Transitioning Clinical Mentoring of HIV Care and Treatment in Ethiopia. AB - Introduction: Focus on improving access and quality of HIV care and treatment gained acceptance in Ethiopia through the work of the International Training and Education Center for Health. The initiative deployed mobile field-based teams and capacity building teams to mentor health care providers on clinical services and program delivery in three regions, namely Tigray, Amhara, and Afar. Transitioning of the clinical mentoring program (CMP) began in 2012 through capacity building and transfer of skills and knowledge to local health care providers and management. Objective: The initiative explored the process of transitioning a CMP on HIV care and treatment to local ownership and documented key lessons learned. Methods: A mixed qualitative design was used employing focus group discussions, individual in-depth interviews, and review of secondary data. The participants included regional focal persons, mentors, mentees, multidisciplinary team members, and International Training and Education Center for Health (I-TECH) staff. Three facilities were selected in each region. Data were collected by trained research assistants using customized guides for interviews and with data extraction format. The interviews were recorded and fully transcribed. Open Code software was used for coding and categorizing the data. Results: A total of 16 focus group discussions and 20 individual in-depth interviews were conducted. The critical processes for transitioning a project were: establishment of a mentoring transition task force, development of a roadmap to define steps and directions for implementing the transition, and signing of a memorandum of understanding (MOU) between the respective regional health bureaus and I-TECH Ethiopia to formalize the transition. The elements of implementation included mentorship and capacity building, joint mentoring, supportive supervision, review meetings, and independent mentoring supported by facility-based mechanisms: multidisciplinary team meetings, case-based discussions, and catchment area meetings. Conclusion: The process of transitioning the CMP to local ownership involved signing an MOU, training of mentors, and building capacity of mentoring in each region. The experience shed light on how to transition donor-supported work to local country ownership, with key lessons related to strengthening the structures of regional health bureaus, and other facilities addressing critical issues and ensuring continuity of the facility-based activities. PMID- 29459891 TI - Evaluating the Sporicidal Activity of Disinfectants against Clostridium difficile and Bacillus amyloliquefaciens Spores by Using the Improved Methods Based on ASTM E2197-11. AB - Spore-forming pathogenic bacteria, such as Clostridium difficile, are associated with nosocomial infection, leading to the increased use of sporicidal disinfectants, which impacts socioeconomic costs. However, C. difficile can be prevented using microorganisms such as Bacillus amyloliquefaciens, a prophylactic agent that has been proven to be effective against it in recent tests or it can be controlled by sporicidal disinfectants. These disinfectants against spores should be evaluated according to a known and recommended standard. Unfortunately, some newly manufactured disinfectants like Bioxy products have not yet been tested. ASTM E2197-11 is a standard test that uses stainless steel disks (1 cm in diameter) as carriers, and the performance of the test formulation is calculated by comparing the number of viable test organisms to that on the control carriers. Surface tests are preferable for evaluating disinfectants with sporicidal effects on hard surfaces. This study applies improved methods, based on the ASTM E2197-11 standard, for evaluating and comparing the sporicidal efficacies of several disinfectants against spores of C. difficile and B. amyloliquefaciens, which are used as the test organisms. With the improved method, all spores were recovered through vortexing and membrane filtration. The results show that chlorine-based products are effective in 5 min and Bioxy products at 5% w/v are effective in 10 min. Although Bioxy products may take longer to prove their effectiveness, their non-harmful effects to hospital surfaces and people have been well established in the literature. PMID- 29459892 TI - Mechanisms of Mitotic Kinase Regulation: A Structural Perspective. AB - Protein kinases are major regulators of mitosis, with over 30% of the mitotic proteome phosphorylated on serines, threonines and tyrosines. The human genome encodes for 518 kinases that have a structurally conserved catalytic domain and includes about a dozen of cell division specific ones. Yet each kinase has unique structural features that allow their distinct substrate recognition and modes of regulation. These unique regulatory features determine their accurate spatio temporal activation critical for correct progression through mitosis and are exploited for therapeutic purposes. In this review, we will discuss the principles of mitotic kinase activation and the structural determinants that underlie functional specificity. PMID- 29459893 TI - Biobehavioral Insights into Adaptive Behavior in Complex and Dynamic Operational Settings: Lessons learned from the Soldier Performance and Effective, Adaptable Response Task. AB - The purpose of this study was to explore the biobehavioral correlates of adaptive behavior in the context of a standardized laboratory-based mission-relevant challenge [the Soldier Performance and Effective, Adaptable Response (SPEAR) task]. Participants were 26 healthy male volunteers (M = 34.85 years, SD = 4.12) with active military duty and leadership experience within the last 5 years (i.e., multiple leadership positions, operational deployments in combat, interactions with civilians and partner nation forces on the battlefield, experience making decisions under fire). The SPEAR task simultaneously engages perception, cognition, and action aspects of human performance demands similar to those encountered in the operational setting. Participants must engage with military-relevant text, visual, and auditory stimuli, interpret new information, and retain the commander's intent in working memory to create a new plan of action for mission success. Time-domain measures of heart period and respiratory sinus arrhythmia (RSA) were quantified, and saliva was sampled [later assayed for cortisol and alpha-amylase (sAA)] before-, during-, and post-SPEAR. Results revealed a predictable pattern of withdraw and recovery of the cardiac vagal tone during repeated presentation of battlefield challenges. Recovery of vagal inhibition following executive function challenge was strongly linked to better task-related performance. Rate of RSA recovery was also associated with better recall of the commander's intent. Decreasing magnitude in the skin conductance response prior to the task was positively associated with better overall task related performance. Lower levels of RSA were observed in participants who reported higher rates of combat deployments, and reduced RSA flexibility was associated with higher rates of casualty exposure. Greater RSA flexibility during SPEAR was associated with greater self-reported resilience. There was no consistent pattern of task-related change in cortisol or sAA. We conclude that individual differences in psychophysiological reactivity and regulation in response to an ecologically valid, military-relevant task are associated with performance-related adaptive behavior in this standardized operational setting. The implications for modern day warfare, where advancing our understanding of the nature of individual differences in adaptive problem solving is critical to mission success, fitness for duty, and other occupational health-related outcomes, are discussed. PMID- 29459894 TI - Idiopathic Pulmonary Fibrosis: Aging, Mitochondrial Dysfunction, and Cellular Bioenergetics. AB - At present, the etiology of idiopathic pulmonary fibrosis (IPF) remains elusive. Over the past two decades, however, researchers have identified and described the underlying processes that result in metabolic dysregulation, metabolic reprogramming, and mitochondrial dysfunction observed in the cells of IPF lungs. Metabolic changes and mitochondrial dysfunction in IPF include decreased efficiency of electron transport chain function with increasing production of reactive oxygen species, decreased mitochondrial biogenesis, and impaired mitochondrial macroautophagy, a key pathway for the removal of dysfunctional mitochondria. Metabolic changes in IPF have potential impact on lung cell function, differentiation, and activation of fibrotic responses. These alterations result in activation of TGF-beta and predispose to the development of pulmonary fibrosis. IPF is a disease of the aged, and many of these same bioenergetic changes are present to a lesser extent with normal aging, raising the possibility that these anticipated alterations in metabolic processes play important roles in creating susceptibility to the development of IPF. This review explores what is known regarding the cellular metabolic and mitochondrial changes that are found in IPF, and examines this body of literature to identify future research direction and potential points of intervention in the pathogenesis of IPF. PMID- 29459895 TI - Enhanced Recovery in Thoracic Surgery: A Review. AB - The main goal of enhanced recovery program after thoracic surgery is to minimize stress response, reduce postoperative pulmonary complications, and improve patient outcome, which will in addition decrease hospital stay and reduce hospital costs. As minimally invasive technique, video-assisted thoracoscopic surgery represents an important element of enhanced recovery program in thoracic surgery. Anesthetic management during preoperative, intraoperative and postoperative period is essential for the enhanced recovery. In the era of enhanced recovery protocols, non-intubated thoracoscopic procedures present a step forward. This article focuses on the key elements of the enhanced recovery program in thoracic surgery. Having reviewed recent literature, the authors highlight potential procedures and techniques that might be incorporated into the program. PMID- 29459896 TI - Redox Status, Procoagulant Activity, and Metabolome of Fresh Frozen Plasma in Glucose 6-Phosphate Dehydrogenase Deficiency. AB - Objective: Transfusion of fresh frozen plasma (FFP) helps in maintaining the coagulation parameters in patients with acquired multiple coagulation factor deficiencies and severe bleeding. However, along with coagulation factors and procoagulant extracellular vesicles (EVs), numerous bioactive and probably donor related factors (metabolites, oxidized components, etc.) are also carried to the recipient. The X-linked glucose 6-phosphate dehydrogenase deficiency (G6PD-), the most common human enzyme genetic defect, mainly affects males. By undermining the redox metabolism, the G6PD- cells are susceptible to the deleterious effects of oxidants. Considering the preferential transfusion of FFP from male donors, this study aimed at the assessment of FFP units derived from G6PD- males compared with control, to show whether they are comparable at physiological, metabolic and redox homeostasis levels. Methods: The quality of n = 12 G6PD- and control FFP units was tested after 12 months of storage, by using hemolysis, redox, and procoagulant activity-targeted biochemical assays, flow cytometry for EV enumeration and phenotyping, untargeted metabolomics, in addition to statistical and bioinformatics tools. Results: Higher procoagulant activity, phosphatidylserine positive EVs, RBC-vesiculation, and antioxidant capacity but lower oxidative modifications in lipids and proteins were detected in G6PD- FFP compared with controls. The FFP EVs varied in number, cell origin, and lipid/protein composition. Pathway analysis highlighted the riboflavin, purine, and glycerolipid/glycerophospholipid metabolisms as the most altered pathways with high impact in G6PD-. Multivariate and univariate analysis of FFP metabolomes showed excess of diacylglycerols, glycerophosphoinositol, aconitate, and ornithine but a deficiency in riboflavin, flavin mononucleotide, adenine, and arginine, among others, levels in G6PD- FFPs compared with control. Conclusion: Our results point toward a different redox, lipid metabolism, and EV profile in the G6PD- FFP units. Certain FFP-needed patients may be at greatest benefit of receiving FFP intrinsically endowed by both procoagulant and antioxidant activities. However, the clinical outcome of G6PD- FFP transfusion would likely be affected by various other factors, including the signaling potential of the differentially expressed metabolites and EVs, the degree of G6PD-, the redox status in the recipient, the amount of FFP units transfused, and probably, the storage interval of the FFP, which deserve further investigation by future studies. PMID- 29459897 TI - Toward the Relevance of Platelet Subpopulations for Transfusion Medicine. AB - Circulating platelets consist of subpopulations with different age, maturation state and size. In this review, we address the association between platelet size and platelet function and summarize the current knowledge on platelet subpopulations including reticulated platelets, procoagulant platelets and platelets exposing signals to mediate their clearance. Thereby, we emphasize the impact of platelet turnover as an important condition for platelet production in vivo. Understanding of the features that characterize platelet subpopulations is very relevant for the methods of platelet concentrate production, which may enrich or deplete particular platelet subpopulations. Moreover, the concept of platelet size being associated with platelet function may be attractive for transfusion medicine as it holds the perspective to separate platelet subpopulations with specific functional capabilities. PMID- 29459898 TI - Parotid Quadrantectomy Is a Safe Management for Localized Pleomorphic Adenoma. AB - Aim: Pleomorphic adenoma is the most common benign tumor of the parotid gland and is classically treated with superficial or total parotidectomy. Less radical surgeries have been proposed to minimize the risk of facial nerve injury. The oncological safety of these procedures remains controversial. We conducted this study to evaluate the safety of superficial hemi-lobectomy (quadrantectomy). Patients and methods: Retrospective analysis was conducted on the paraffin sections of archived superficial parotidectomy specimens from 11 male and 6 female patients (median age 33 years). The microscopic extent of extra-capsular extension was determined on pathological revision. In addition, prospective evaluation of 12 quadrantectomy procedures (M/F = 7/5, median age = 36 years) compared to 24 radical surgeries (M = F, median age = 40 years) regarding temporary and persistent facial nerve dysfunction on routine clinical assessment and recurrence rate. Results: On retrospective pathological revision, pleomorphic adenomata had a median microscopic spread of 3 mm beyond capsule in paraffin sections (SD = 3.6). On prospective analysis with a median follow-up of 33 months (range = 18-54 months), quadrantectomy had similar relative risk of temporary facial nerve dysfunction evaluated at the immediate postoperative period as well as persistent nerve dysfunction assessed at 3 months (P = 0.701 and P = 0.902, respectively). Of the whole study population, one case of recurrence after total parotidectomy was observed at mid-term follow-up (P = 1.000). Conclusion: Parotid quadrantectomy is a safe management for smaller pleomorphic adenomata localized close to one of the two divisions of the facial nerve. PMID- 29459899 TI - Structural Changes of RNA in Complex with Proteins in the SRP. AB - The structural flexibility of RNA allows it to exist in several shapes and sizes. Thus, RNA is functionally diverse and is known to be involved in processes such as catalysis, ligand binding, and most importantly, protein recognition. RNA can adopt different structures, which can often dictate its functionality. When RNA binds onto protein to form a ribonucleoprotein complex (RNP), multiple interactions and conformational changes occur with the RNA and protein. However, there is the question of whether there is a specific pattern for these changes to occur upon recognition. In particular when RNP complexity increases with the addition of multiple proteins/RNA, it becomes difficult to structurally characterize the overall changes using the current structural determination techniques. Hence, there is a need to use a combination of biochemical, structural and computational modeling to achieve a better understanding of the processes that RNPs are involved. Nevertheless, there are well-characterized systems that are evolutionarily conserved [such as the signal recognition particle (SRP)] that give us important information on the structural changes of RNA and protein upon complex formation. PMID- 29459901 TI - Mechanisms and Therapeutic Targets of Cardiac Regeneration: Closing the Age Gap. AB - While a regenerative response is limited in the mammalian adult heart, it has been recently shown that the neonatal mammalian heart possesses a marked but transient capacity for regeneration after cardiac injury, including myocardial infarction. These findings evidence that the mammalian heart still retains a regenerative capacity and highlights the concept that the expression of distinct molecular switches (that activate or inhibit cellular mechanisms regulating tissue development and regeneration) vary during different stages of life, indicating that cardiac regeneration is an age-dependent process. Thus, understanding the mechanisms underpinning regeneration in the neonatal-infarcted heart is crucial to develop new treatments aimed at improving cardiovascular regeneration in the adult. The present review summarizes the current knowledge on the pathways and factors that are known to determine cardiac regeneration in the neonatal-infarcted heart. In particular, we will focus on the effects of microRNA manipulation in regulating cardiomyocyte proliferation and regeneration, as well as on the role of the Hippo signaling pathway and Meis1 in the regenerative response of the neonatal-infarcted heart. We will also briefly comment on the role of macrophages in scar formation of the adult-infarcted heart or their contribution for scar-free regeneration of the neonatal mouse heart after myocardial infarction. Although additional research is needed in order to identify other factors that regulate cardiovascular regeneration, these pathways represent potential therapeutic targets for rejuvenation of aging hearts and for improving regeneration of the adult-infarcted heart. PMID- 29459902 TI - Whole Brain Parcellation with Pathology: Validation on Ventriculomegaly Patients. AB - Numerous brain disorders are associated with ventriculomegaly; normal pressure hydrocephalus (NPH) is one example. NPH presents with dementia-like symptoms and is often misdiagnosed as Alzheimer's due to its chronic nature and nonspecific presenting symptoms. However, unlike other forms of dementia NPH can be treated surgically with an over 80% success rate on appropriately selected patients. Accurate assessment of the ventricles, in particular its sub-compartments, is required to diagnose the condition. Existing segmentation algorithms fail to accurately identify the ventricles in patients with such extreme pathology. We present an improvement to a whole brain segmentation approach that accurately identifies the ventricles and parcellates them into four sub-compartments. Our work is a combination of patch-based tissue segmentation and multi-atlas registration-based labeling. We include a validation on NPH patients, demonstrating superior performance against state-of-the-art methods. PMID- 29459903 TI - Editorial: Modifying risk factors - the next step. PMID- 29459900 TI - Kruppel-Like Factors in Vascular Inflammation: Mechanistic Insights and Therapeutic Potential. AB - The role of inflammation in vascular disease is well recognized, involving dysregulation of both circulating immune cells as well as the cells of the vessel wall itself. Unrestrained vascular inflammation leads to pathological remodeling that eventually contributes to atherothrombotic disease and its associated sequelae (e.g., myocardial/cerebral infarction, embolism, and critical limb ischemia). Signaling events during vascular inflammation orchestrate widespread transcriptional programs that affect the functions of vascular and circulating inflammatory cells. The Kruppel-like factors (KLFs) are a family of transcription factors central in regulating vascular biology in states of homeostasis and disease. Given their abundance and diversity of function in cells associated with vascular inflammation, understanding the transcriptional networks regulated by KLFs will further our understanding of the pathogenesis underlying several pervasive health concerns (e.g., atherosclerosis, stroke, etc.) and consequently inform the treatment of cardiovascular disease. Within this review, we will discuss the role of KLFs in coordinating protective and deleterious responses during vascular inflammation, while addressing the potential targeting of these critical transcription factors in future therapies. PMID- 29459904 TI - Evaluating the Clinical Use of Light-emitting Diode vs Halogen Photocuring Units. AB - PURPOSE: To clinically examine the effect of the type of ight-curing unit on the light intensity output and to assess different operator variables which affect light curing of photo-initiated restorative dental materials, in Damascus, Syria. MATERIALS AND METHODS: A total of 185 private dental practices in the Damascus area were visited to invite the clinicians to participate in this study. The intensity of 163 light-curing units (LCUs) was assessed by radiometry in a standard protocol. The age of the curing unit, light tip direction, distance from restoration surface, time of exposure and the presence of adherent composite remnants on the tip of the light pipe were assessed. Independent samples t-tests and ANOVA with Bonferroni post-hoc tests were conducted (p = 0.05). RESULTS: The light intensity was affected significantly by the type of the LCU (p < 0.001). The increased age of light-curing units significantly reduced the emitted light intensity in LED and QTH units (p < 0.05). The presence of adherent resin composite remnants on the pipe tip of the curing unit was monitored in 74 cases out of 163 (45%). The disinfection wipe was the most common method used to ensure infection control of the curing units. CONCLUSION: LED units exhibited a significantly better light intensity output at the tip when compared to the QTH units. It is important for dentists to consider all practical aspects which can influence the efficacy of LCUs in daily practice. PMID- 29459906 TI - Assessment of Oral Health Related Quality of Life Among the Institutionalised Elderly in Delhi, India. AB - PURPOSE: To assess the oral health related quality of life (OHRQoL) among older people residing in old-age homes in Delhi, India. MATERIALS AND METHODS: Oral health related quality of life was measured by using the Hindi version of Geriatric Oral Health Assessment Index (GOHAI) which was tested for its reliability and validity. Sociodemographic data were collected and questions regarding the self-perception of general health, oral health and perceived need for dental treatment were put forward. Clinical assessment was also performed. RESULTS: The mean additive-GOHAI score of the study population was found to be 41.57 +/- 6.07. Statistically significant associations were found between GOHAI and perceived measures. GOHAI scores decreased with a decrease in the number of teeth present and a decrease in the number of teeth having coronal and root caries. Those subjects who were in need of multi-unit prostheses or full prostheses had significantly poorer OHRQoL compared to those without any prosthetic need or need of single-unit prostheses. CONCLUSION: This study revealed the extent of dental problems in old-age home residents and may help to plan appropriate preventive measures. PMID- 29459905 TI - Perception of Treatment Needs and Use of Dental Services for Children and Adolescents with Sickle Cell Disease. AB - PURPOSE: To evaluate the perception of treatment needs and the use of dental services for children/adolescents with sickle cell disease. MATERIALS AND METHODS: A cross-sectional study was conducted with 250 children/adolescents with sickle cell disease at a reference center in the city of Recife, Brazil. Data on the use of dental services were collected using a 13-item questionnaire administered to parents/guardians. The examiner in charge of determining l caries and periodontal status had previously undergone a training and calibration exercise. Descriptive statistics and Poisson regression analysis were also performed (alpha = 5%). RESULTS: A total of 47.2% of the children/adolescents with sickle cell disease were diagnosed with caries and 14.0% were diagnosed with some periodontal problems. The following variables were statistically significantly associated with the perceptions of parents/guardians regarding the treatment needs of their children: caries (PR = 1.24; 95%CI: 1.09-1.42), periodontal problems (PR = 1.10; 95%CI 1.01-1.20) and history of toothache in the previous six months (PR = 1.17; 95%CI 1.06-1.29). Only a lower level of mothers' schooling (PR = 1.64; 95%CI 1.06-2.53) was statistically significantly associated with the mean number of caries among the children/adolescents with sickle cell disease. Mean dmft/DMFT indices were higher among children/adolescents who sought dental care. CONCLUSION: Based on our results, a predomination of curative treatment was found, as seeking out dental treatment was more frequent among children/adolescents with a greater number of caries. PMID- 29459907 TI - Impact of Chronic Kidney Disease Mineral and Bone Disorder on Jaw and Alveolar Bone Metabolism: A Narrative Review. AB - Chronic kidney disease (CKD) has become a worldwide public health problem. It is estimated that nearly 90% of patients with chronic renal failure manifest some symptoms of oral disease. With advances in medical treatment, CKD patients are living longer and require oral care. Chronic kidney disease is often accompanied by disturbances in mineral metabolism which are classified as their own clinical entity known as CKD-mineral and bone disorder (CKD-MBD). CKD-MBD affects all aspects of bone physiology: bone volume, bone turnover and bone mineralization. Jaw bones affected with CKD-MBD can have important clinical implications for the survival and osseointegration of dental implants, success of bone regeneration therapy, and increased risk of bone loss in patients with periodontitis or risk of bone fracture. Assessment of bone turnover is the most important diagnostic tool to monitor progression of CKD-MBD. Bone biomarkers and radiographical examination of bone density may be particularly useful to both, diagnosis and monitoring of bone turnover. Cone beam computed tomography (CBCT) as a reliable method with many advantages over other radiographic methods can be used for analysis of jaw bone micro-architectural changes and may be of a great help in bone quality determination in CKD-MBD. PMID- 29459908 TI - Trends in Early Childhood Caries: An Italian Perspective. AB - PURPOSE: To evaluate the prevalence of early childhood caries (ECC) and severe ECC (S-ECC) among Italian preschool children and its predictors regarding children's lifestyle. MATERIALS AND METHODS: A cross-sectional study was carried out involving 563 preschool children. A questionnaire for children's parents and clinical examinations were conducted by calibrated, blinded examiners. The odds ratios (OR) for ECC or S-ECC and co-presence of risk factors were calculated using univariate and multivariate models. Statistical significance was set at p < 0.05 in all analyses. RESULTS: The prevalence of ECC and S-ECC was 14.4% and 5.9%, respectively. According to the multivariate analysis, the predictors for caries were (p < 0.05): age (OR = 2.5; 95% CI = 1.36 - 4.52), non-Italian ethnic origin (OR = 4.3; 95% CI = 2.83 - 7.37), consumption of sugary beverages more than once per day (OR = 2.1; 95% CI = 1.21 - 5.26) and having inadequate oral hygiene status (OR = 3.6; 95% CI = 2.01 - 5.83). CONCLUSIONS: Dietary habits and dental care are important environmental contributing factors in the development of caries in preschool children. Oral health promotion should include an oral hygiene instruction programme and dietary guidelines focused on daily sugar intake for the preschool children themselves as well as for their parents.

AB - PURPOSE: Dental caries is the primary pathological cause of early tooth loss in children, which may lead to malnutrition and other health problems. Identification of patients with active carious lesions and at high risk for caries can help to dramatically decrease the disease prevalence. Thus, recognising the importance of early diagnosis of caries, the present study was carried out to correlate caries with oral microflora using Oratest among 12- to 15-year-old schoolchildren. MATERIALS AND METHODS: A total of 100 children were divided into control and test groups (n = 50) according to their DMFT scores. The test group was further divided into subgroup 1 (DMFT = 1-3) and subgroup 2 (DMFT > 3). Oratest, a caries activity test, was performed on all the children. Comparison among the variables was done using ANOVA and the independent sample t test. RESULTS: Boys had lower DMFT values (1.35 +/- 0.2) than did girls (1.67 +/- 0.2) (p = 0.38), and the Oratest time was higher among boys (132.8 +/- 0.5 min) than girls (126.4 +/- 0.5 min) (p = 0.53). The control group had the highest mean Oratest time (172.7 +/- 0.3 min), followed by subgroup 1 (97.8 +/- 0.2 min), and subgroup 2 had the lowest Oratest time (68.5 +/- 14.8 min). A statistically significant negative correlation (r = -0.893) was found between the mean DMFT and the Oratest time (p < 0.001), ie, they were inversely related to each other. CONCLUSION: An inverse relationship exists between Oratest and DMFT score. PMID- 29459910 TI - Fabrication of tough epoxy with shape memory effects by UV-assisted direct-ink write printing. AB - 3D printing of epoxy-based shape memory polymers with high mechanical strength, excellent thermal stability and chemical resistance is highly desirable for practical applications. However, thermally cured epoxy in general is difficult to print directly. There have been limited numbers of successes in printing epoxy but they suffer from relatively poor mechanical properties. Here, we present an ultraviolet (UV)-assisted 3D printing of thermally cured epoxy composites with high tensile toughness via a two-stage curing approach. The ink containing UV curable resin and epoxy oligomer is used for UV-assisted direct-ink write (DIW) based 3D printing followed by thermal curing of the part containing the epoxy oligomer. The UV curable resin forms a network by photo polymerization after the 1st stage of UV curing, which can maintain the printed architecture at an elevated temperature. The 2nd stage thermal curing of the epoxy oligomer yields an interpenetrating polymer network (IPN) composite with highly enhanced mechanical properties. It is found that the printed IPN epoxy composites enabled by the two-stage curing show isotropic mechanical properties and high tensile toughness. We demonstrated that the 3D-printed high-toughness epoxy composites show good shape memory properties. This UV-assisted DIW 3D printing via a two stage curing method can broaden the application of 3D printing to fabricate thermoset materials with enhanced tensile toughness and tunable properties for high-performance and functional applications.

AB - The essential omega-3 fatty acid alpha-linolenic acid (ALA, 18:3n3) can be converted into EPA and DHA. The aim of the present study was to determine the effect of a high-ALA diet on EPA and DHA levels in red blood cells (RBCs) and their oxylipins in the plasma of subjects with a low EPA and DHA status. Fatty acid concentrations [MUg mL-1] and relative amounts [% of total fatty acids] in the RBCs of 19 healthy men (mean age 26.4 +/- 4.6 years) were analyzed by means of GC-FID. Free plasma oxylipin concentrations were determined by LC-MS based targeted metabolomics. Samples were collected and analyzed at baseline (week 0) and after 1 (week 1), 3 (week 3), 6 (week 6), and 12 (week 12) weeks of high dietary ALA intake (14.0 +/- 0.45 g day-1). ALA concentrations significantly (p < 0.001) increased from 1.44 +/- 0.10 (week 0) to 4.65 +/- 0.22 (week 1), 5.47 +/- 0.23 (week 3), 6.25 +/- 0.24 (week 6), and 5.80 +/- 0.28 (week 12) MUg mL-1. EPA concentrations increased from 6.13 +/- 0.51 (week 0) to 7.33 +/- 0.33 (week 1), 8.38 +/- 0.42 (p = 0.021, week 3), 10.9 +/- 0.67 (p < 0.001, week 6), and 11.0 +/ 0.64 (p < 0.001, week 12) MUg mL-1. DHA concentrations unexpectedly decreased from 41.0 +/- 1.93 (week 0) to 37.0 +/- 1.32 (week 1), 36.1 +/- 1.37 (week 3), 35.1 +/- 1.06 (p = 0.010, week 6), and 30.4 +/- 1.09 (p < 0.001, week 12) MUg mL 1. Relative SigmaEPA + DHA amounts were unchanged during the intervention (week 0: 4.63 +/- 0.19, week 1: 4.67 +/- 0.16, week 3: 4.61 +/- 0.13, week 6: 4.73 +/- 0.15, week 12: 4.52 +/- 0.11). ALA- and EPA-derived hydroxy- and dihydroxy-PUFA increased similarly to their PUFA precursors, although in the case of ALA-derived oxylipins, the concentrations increased less rapidly and to a lesser extent compared to the concentrations of their precursor FA. LA-derived oxylipins remained unchanged and arachidonic acid and DHA oxylipin concentrations were not significantly changed. Our results confirm that the intake of ALA is not a sufficient source for the increase of EPA + DHA in subjects on a Western diet. Specifically, a high-ALA diet results in increased EPA and declined DHA concentrations. However, the changes effectively balance each other out so that SigmaEPA + DHA in RBCs - which is an established marker for health protective effects of omega-3-PUFA - remains constant. The PUFA levels in RBCs reflect the concentration and its changes in plasma hydroxy- and dihydroxy-PUFA concentrations for ALA and EPA.

AB - While the cytotoxicity of graphene oxide (GO) has been well established, its bactericidal mechanism, however, has yet to be elucidated to advance GO-based biomedical and environmental applications. In an attempt to better understand the bactericidal action of GO, herein we studied the interactions of GO with Gram negative Escherichia coli and Gram-positive Staphylococcus aureus cells using physical techniques and chemical probes, respectively. In particular, a novel laser-induced breakdown spectroscopy (LIBS) based elemental fingerprint analysis revealed notable differences between viable and non-viable cells based on the difference in the concentration of trace inorganic elements in complex bacterial systems, which reflect cellular membrane integrity. Lower emission intensities from essential inorganic ions in the GO-treated cells offered explicit evidence on the efflux of intracellular molecules from the bacteria through damaged cell membranes. Furthermore, a detailed structural and morphological investigation of bacterial membrane integrity confirmed GO-induced membrane stress upon direct contact interactions with bacterial cells, resulting in the disruption of cellular membranes. Moreover, the generation of intracellular reactive oxygen species (ROS) in the presence of an added antioxidant underlined the role of GO mediated oxidative stress in bacterial cell inactivation. Thus, by correlating the changes in the bacterial elemental compositions with the severe morphological alterations and the high ROS production witnessed herein, we propose that the bactericidal mechanism of GO is likely to be the synergy between membrane and oxidative stress towards both tested species. Our findings offer useful guidelines for the future development of GO-based antibacterial surfaces and coatings.

AB - Constructing surface disorder including grain boundaries, stacking faults, and dislocation arrays in nanomaterials is an important strategy to enhance the catalytic activity of nanocatalysts.

PMID- 29459915 TI - Microfluidic label-free selection of mesenchymal stem cell subpopulation during culture expansion extends the chondrogenic potential in vitro. AB - Mesenchymal stem cells (MSCs) have been shown as potential candidates for cell based therapies for a diverse range of tissue regenerative applications. Therapeutic use of MSCs usually requires culture expansion, which increases the heterogeneity of MSCs in vitro, thus affecting the potency of the MSCs for more specific indications. The capacity for identifying and isolating special subsets of MSCs for treatment of specific diseases therefore holds great clinical significance. An important therapeutic application of MSC is for the regeneration of cartilage tissue. We and others have previously developed label-free microfluidic means to isolate subpopulations of culture expanded MSCs based on distinct biophysical characteristics. Here we utilize a spiral micro-channel device to separate culture expanded MSCs into five subgroups according to cell size, and study their proliferation and chondrogenesis at early, middle and late passages. Results show that in all passages, the medium-size subpopulation (cell size of 17-21 MUm), compared to other subpopulations, displays significantly higher proliferation rate and chondrogenic capacity in terms of cartilage extracellular matrix formation. Also, the small cell subpopulation (average cell size of 11-12 MUm) shows lower viability, and large cell subpopulation (average cell size 23-25 MUm) expresses higher level of senescence-associated beta galactosidase. Finally, we show that repeated microfluidic exclusion of MSCs larger than 21 MUm and smaller than 17 MUm at every passage during continuous culture expansion result in selected MSCs with faster proliferation and better chondrogenic potential as compared to MSC derived from conventional expansion approach. This study demonstrates the significant merit and utility of size-based cell selection for the application of MSCs in cartilage regeneration. PMID- 29459916 TI - UV-induced long-lived decays in solvated pyrimidine nucleosides resolved at the MS-CASPT2/MM level. AB - The most relevant 'dark' electronic excited states in DNA/RNA pyrimidine nucleosides are mapped in water employing hybrid MS-CASPT2/MM optimisations with explicit solvation and including the sugar. Conical intersections (CIs) between initially accessed bright 1pipi* and the lowest energy dark 1npi* excited states, involving the lone pair localised on the oxygen and/or nitrogen atoms are characterised. They are found in the vicinities of the Franck-Condon (FC) region and are shown to facilitate non-adiabatic population transfer. The excited state population of the 1nOpi* state, localised in the carbonyl moiety on all pyrimidine nucleosides, is predicted to rapidly evolve to its minimum, displaying non-negligible potential energy barriers along its non-radiative decay, and accounting for the ps signal registered in pump-probe experiments as well as for an efficient population of the triplet state. Cytidine displays an additional 1nNpi* state localised in the N3 atom and that leads to its excited state minimum displaying large potential energy barriers in the pathway connecting to the CI with the ground state. Sugar-to-base hydrogen/proton transfer processes are assessed in solution for the first time, displaying a sizable barrier along its decay and thus being competitive with other slow decay channels in the ps and ns timescales. A unified deactivation scheme for the long-lived channels of pyrimidine nucleosides is delivered, where the 1nOpi* state is found to mediate the long-lived decay in the singlet manifold and act as the doorway for triplet population and thus accounting for the recorded phosphorescence and, more generally, for the transient/photoelectron spectral signals registered up to the ns timescale. PMID- 29459919 TI - Quantifying atom-scale dopant movement and electrical activation in Si:P monolayers. AB - Advanced hydrogen lithography techniques and low-temperature epitaxial overgrowth enable the patterning of highly phosphorus-doped silicon (Si:P) monolayers (ML) with atomic precision. This approach to device fabrication has made Si:P monolayer systems a testbed for multiqubit quantum computing architectures and atomically precise 2-D superlattice designs whose behaviors are directly tied to the deterministic placement of single dopants. However, dopant segregation, diffusion, surface roughening, and defect formation during the encapsulation overgrowth introduce large uncertainties to the exact dopant placement and activation ratio. In this study, we develop a unique method by combining dopant segregation/diffusion models with sputter profiling simulation to monitor and control, at the atomic scale, dopant movement using room-temperature grown locking layers (LLs). We explore the impact of LL growth rate, thickness, rapid thermal annealing, surface accumulation, and growth front roughness on dopant confinement, local crystalline quality, and electrical activation within Si:P 2-D systems. We demonstrate that dopant movement can be more efficiently suppressed by increasing the LL growth rate than by increasing the LL thickness. We find that the dopant segregation length can be suppressed below a single Si lattice constant by increasing the LL growth rates at room temperature while maintaining epitaxy. Although dopant diffusivity within the LL is found to remain high (on the order of 10-17 cm2 s-1) even below the hydrogen desorption temperature, we demonstrate that exceptionally sharp dopant confinement with high electrical quality within Si:P monolayers can be achieved by combining a high LL growth rate with low-temperature LL rapid thermal annealing. The method developed in this study provides a key tool for 2-D fabrication techniques that require precise dopant placement to suppress, quantify, and predict a single dopant's movement at the atomic scale. PMID- 29459920 TI - Amplification-free detection of DNA in a paper-based microfluidic device using electroosmotically balanced isotachophoresis. AB - We present a novel microfluidic paper-based analytical device (MUPAD) which utilizes the native high electroosmotic flow (EOF) in nitrocellulose to achieve stationary isotachophoresis (ITP) focusing. This approach decouples sample accumulation from the length of the channel, resulting in significant focusing over short channel lengths. We provide a brief theory for EOF-balanced ITP focusing under continuous injection from a depleting reservoir and present the design of a short (7 mm) paper-based microfluidic channel, which allows a 200 MUL sample to be processed in approximately 6 min, resulting in a 20 000-fold increase in concentration - a full order of magnitude improvement compared to previous paper-based ITP devices. We show the stability of the assay over longer (40 min) durations of time, and using Morpholino probes, we present the applicability of the device for amplification-free detection of nucleic acids, with a limit-of-detection (LoD) of 5 pM in 10 min. Finally, we utilize the small footprint of the channel and show a multiplexed platform in which 12 assays operate in parallel in a 24-well plate format.

AB - Enclosing functional nanoparticles in stable inorganic supports is important for generating ultra-stable catalytic active sites with good performance and material utilization efficiency. Here we describe a simple method to synthesize ultra-thin Ag nanocrystals with dimensions that are defined by the ~1.4 nm 2D interlayer separating a layered silicate nanostructure. We call the particles "nanoplates" because they are <1.4 nm thick in one direction and their in-plane dimensions are defined by reaction time. The layered silicate is pillared with dialkylurea, which serves both as a reducing agent for the Ag precursor and immobilizes the Ag nanoplates in the interstitial nanospace. The supported Ag nanoplates showed catalytic activity for hydrolysis of NH3BH3 and generation of H2 at room temperature. These supported Ag nanocatalysts had performance much higher than spherical Ag nanoparticles. They, moreover, had performance and stability comparable to costly supported Pt nanoparticles.

PMID- 29459925 TI - Investigation of hydrophobic substrates for solution residue analysis utilizing an ambient desorption liquid sampling-atmospheric pressure glow discharge microplasma. AB - A practical method for preparation of solution residue samples for analysis utilizing the ambient desorption liquid sampling-atmospheric pressure glow discharge optical emission spectroscopy (AD-LS-APGD-OES) microplasma is described. Initial efforts involving placement of solution aliquots in wells drilled into copper substrates, proved unsuccessful. A design-of-experiment (DOE) approach was carried out to determine influential factors during sample deposition including solution volume, solute concentration, number of droplets deposited, and the solution matrix. These various aspects are manifested in the mass of analyte deposited as well as the size/shape of the product residue. Statistical analysis demonstrated that only those initial attributes were significant factors towards the emission response of the analyte. Various approaches were investigated to better control the location/uniformity of the deposited sample. Three alternative substrates, a glass slide, a poly(tetrafluoro)ethylene (PTFE) sheet, and a polydimethylsiloxane (PDMS)-coated glass slide, were evaluated towards the microplasma analytical performance. Co deposition with simple organic dyes provided an accurate means of determining the location of the analyte with only minor influence on emission responses. The PDMS coated glass provided the best performance by virtue of its providing a uniform spatial distribution of the residue material. This uniformity yielded an improved limits of detection by approximately 22* for 20 MUL and 4 x for 2 MUL over the other two substrates. While they operate by fundamentally different processes, this choice of substrate is not restricted to the LS-APGD, but may also be applicable to other AD methods such as DESI, DART, or LIBS. Further developments will be directed towards a field-deployable ambient desorption OES source for quantitative analysis of microvolume solution residues of nuclear forensics importance.

It provides convenient access to a variety of synthetically and pharmaceutically important quinolines in moderate to good yields. Control experiments suggest that the cascade reaction might proceed via the Pd-catalyzed electrophilic cyclization of N-aryl propargylamines followed by a hydroarylation process through trapping of the sigma-quinolinylpalladium intermediate with a second molecule of the substrate.

AB - NIR light-induced imaging-guided cancer therapy is an encouraging route in the cancer theranostic field. Herein, we describe a novel nanoscale proposal, which is established by covalently implanting core-shell structured upconversion nanoparticles (UCNPs) with nanographene oxide (NGO) by a process utilizing polyethylene glycol (PEG), and consequently loading Chlorin e6 (Ce6) onto the surface of NGO. The acquired NGO-UCNP-Ce6 (NUC) nanocomposites can not only be employed as upconversion luminescence (UCL) imaging probes of cells and whole body animals with high contrast for diagnosis, but also can generate reactive oxygen species (ROS) under 808 nm light excitation for photodynamic therapy (PDT); over and above, they can swiftly and proficiently translate the 808 nm photon into thermal energy for photothermal therapy (PTT). An extraordinarily enhanced and synchronized therapeutic effect paralleled to the individual PTT or PDT is achieved, rendering extraordinary therapeutic effectiveness for cancer treatment. Consequently, profiting from this inimitable multifunctional nanohybrid, the NUCs synthesized here are encouraging as a cohesive theranostic probe for impending UCL imaging-guided combinatorial PDT/PTT. PMID- 29459930 TI - Optimizing interfacial transport properties of InO2 single atomic layers in In2O3(ZnO)4 natural superlattices for enhanced high temperature thermoelectrics. AB - In2O3(ZnO)k natural superlattices (where k is an integer), consisting of relatively earth abundant and non-toxic elements with coarsening-resistant nanostructures, are environmentally friendly materials with the potential for high temperature thermoelectric applications. Herein, we report our investigation of the high temperature thermoelectric properties of the In2O3(ZnO)4 superlattice bulk polycrystals that were singly and dually doped with Al and Ce. Transport property measurements revealed that Al and Ce did not only enter the ZnO blocks but also modified the InO2 single atomic layers. The effective electron potential barrier height of the superlattice interfaces can be adjusted by doping, and the optimal value that maximizes the power factor is of the order of kBT above the Fermi level. The interfacial thermal (Kapitza) resistance of the InO2 atomic sheets dramatically increased with doping, primarily accounting for the bulk thermal conductivity reduction. At the optimal crossing of the interfacial thermal resistance and the effective potential barrier height, a maximum ZT of ~0.22 was achieved at 800 degrees C in the 1.6 mol% Al-doped superlattice, which was an enhancement of ~200% over the pristine In2O3(ZnO)4. This work provides a new perspective on enhancing the high temperature thermoelectric performance of nanostructured oxides by synergistically optimizing the interfacial phonon and electron transport properties. PMID- 29459931 TI - Versatile reactivities of rare-earth metal dialkyl complexes supported by a neutral pyrrolyl-functionalized beta-diketiminato ligand. AB - Herein, rare-earth metal dialkyl complexes supported by a neutral pyrrolyl functionalized beta-diketiminato ligand with the formula LRE(CH2SiMe3)2(thf) (RE = Y (1a), Dy (1b), Er (1c), Yb (1d); L = MeC(NDipp)CHC(Me)NCH2CH2NC4H2-2,5-Me2, Dipp = 2,6-iPr2C6H3) were synthesized via the reactions of the beta-diketimine HL with the rare-earth metal trialkyl complexes RE(CH2SiMe3)3(thf)2 in high yields. The reactivities of 1 with pyridine derivatives, unsaturated substrates, and elemental sulfur were investigated, and some interesting chemical transformations were observed. Ligand exchange and activation of sp2 and sp3 C-H bonds occurred during the reactions with pyridine derivatives to afford different types of mononuclear rare-earth metal pyridyl complexes, namely, LEr(CH2SiMe3)2(eta1 NC5H4) (2c), LRE(eta3-CH2-2-NC5H2-4,6-Me2)2 (RE = Y (3a), Er (3c)), and LRE(CH2SiMe3)(eta2-(C,N)-2-(2-C6H4NC5H4)) (RE = Er (4c), Yb = (4d)). Similarly, activation of the sp C-H bond occurred during the reaction of phenylacetylene with 1c to produce the dinuclear erbium alkynyl complex [LEr(CH2SiMe3)(MU C[triple bond, length as m-dash]CPh)]2 (5c). The mixed amidinate-beta diketiminato ytterbium complex LYb[(Dipp)NC(CH2SiMe3)N(Dipp)](CH2SiMe3) (6d) was obtained by the insertion of bis(2,6-diisopropylphenyl)carbodiimide into a Yb alkyl bond, as well as via the direct alkane elimination of a CH2SiMe3 moiety with bis(2,6-diisopropylphenyl)formamidine to afford the erbium complex LEr(DippNCHNDipp)(CH2SiMe3) (7c). A rare sp2 C-H bond oxidation of the beta diketiminato backbone with elemental sulfur insertion was detected to provide the unprecedented dinuclear rare-earth metal thiolate complexes (LRE)2(MU SCH2SiMe3)2(MU-SCC(Me)(NDipp)C(Me)NCH2CH2NC4H2Me2-2,5) (RE = Y (8a), Er (8c)) in the reactions of S8 with 1a and 1c, respectively. The molecular structures of the complexes 1-8 were determined by single-crystal X-ray diffraction analyses.

AB - A stable and porous porphyrinic metal-organic framework, Ru-PMOF-1(Hf), has been prepared through the self-assembly of [5,10,15,20-tetrakis(4 carboxyphenyl)porphyrinato](monocarbonyl)ruthenium (Ru(TCPP)(CO)) and HfCl4. Single-crystal X-ray diffraction analysis reveals that Ru-PMOF-1(Hf) possesses a three-dimensional (3D) structure with orthogonal 1D open channels of 1.9 * 1.9 nm2. The porous nature has been confirmed by gas adsorption measurements. Its catalytic activity for the carbene insertion into N-H bonds has been investigated. The catalytic results indicate that Ru-PMOF-1(Hf) is efficient for the insertion reactions of ethyl 2-diazoacetate (EDA) into a range of secondary amines with up to 92% yield, 938 TON and 2475 h-1 TOF. As an excellent heterogeneous catalyst, Ru-PMOF-1(Hf) can be recovered and reused for at least ten runs with negligible loss of catalytic activity. Due to its uniform microporosity in three orthogonal directions, Ru-PMOF-1(Hf), of which the particle sizes were carefully controlled by sieving, can induce size selectivity regarding the amine substrates. The reactivities of different unbranched dialkylamines, such as diethylamine (NHEt2), dibutylamine (NHBu2) and dipentylamine (NHPent2), have been compared, and the results display an apparent decreasing trend along the chain lengthening. For comparison, the corresponding nonporous and homogeneous catalyst Ru(TMCPP)(CO) (TMCPP = tetrakis(4 methoxycarbonylphenyl)porphyrin) displays negligible difference towards the reactions with these three amines. PMID- 29459933 TI - Urinary benzophenone-type UV filters in people living in South China: rural versus urban areas. AB - Benzophenone (BP)-type UV filters are widely used in sunscreen products to protect human skin from UV radiation. However, only a few studies have been conducted to determine the level of human exposure to BPs in rural areas of China. In this study, we evaluated the exposure levels of people living in three villages and a city in South China to five major BPs (BP-1, BP-2, BP-3, BP-8, and 4-OH-BP). The detection rates of BP-1, BP-3, and 4-OH-BP were 66%, 72%, and 75%, respectively, in rural areas and 85%, 75%, and 80%, correspondingly, in urban areas. BP-2 and BP-8 were rarely detected. The results indicated that people living in South China are extensively exposed to BPs, regardless of sampling sites (rural and urban areas). The observed concentrations of BP-1 (urban vs. rural = 1.04 ng mL-1vs. 0.21 ng mL-1) and BP-3 (0.37 ng mL-1vs. 0.16 ng mL-1) were significantly (one-way ANOVA, p < 0.01) lower in the rural areas than in the urban areas. BP-1 (59%) based on composition profile analysis was the dominant BP derivative in urine samples of urban residents, whereas 4-OH-BP (36%) was the most prevalent BP in rural areas. In the rural areas, significant positive correlations between urinary BP-1 and BP-3 (r = 0.529, p < 0.01) and between urinary BP-1 and 4-OH-BP (r = 0.323, p < 0.05) concentrations were obtained; in the urban areas, we only observed a clear correlation (p < 0.01) between BP-1 and 4-OH-BP. The different composition profiles and associations among urinary BPs indicated that exposure sources of BPs might be different between rural and urban areas. The distribution profiles of BP-1 and its parent compound (i.e., BP-3) in urine decreased with the age of adults (r = -0.410, p < 0.01) in the rural areas.

AB - Three dimensional cell culture systems have witnessed rapid expansion in the fields of tissue engineering and drug testing owing to their inherent ability to mimic native tissue microenvironments. High throughput technologies have also facilitated rapid and reproducible generation of spheroids and subsequently their use as in vitro tissue models in drug screening platforms. However, drug screening technologies are in need of monitoring platforms to study these 3D culture models. In this work we present a novel platform to measure the electrical impedance of 3D spheroids, through the use of a planar organic electrochemical transistor (OECT) and a novel circular-shaped microtrap. A new strategy was generated to overcome incompatibility of the integration of polydimethylsiloxane (PDMS) microdevices with OECT fabrication. The impedance platform for 3D spheroids was tested by using spheroids formed from mono-cultures of fibroblast and epithelial cells, as well as co-culture of the two cell types. We validated the platform by showing its ability to measure the spheroid resistance (Rsph) of the 3D spheroids and differences in Rsph were found to be related to the ion permeability of the spheroid. Additionally, we showed the potential use of the platform for the on-line Rsph monitoring when a co-culture spheroid was exposed to a porogenic agent affecting the integrity of the cell membrane.

Contemporary mortality risk estimates of combustible tobacco product use are needed. Objective: To investigate the mortality risks associated with current and former use of cigars, pipes, and cigarettes. Design, Setting, and Participants: The National Longitudinal Mortality Study is a longitudinal population-based, nationally representative health survey with mortality follow-up that includes demographic and other information from the Current Population Survey, tobacco product use information from the Tobacco Use Supplement, and mortality data from the National Death Index. In this study, participants provided tobacco use information at baseline in surveys starting from 1985 and were followed for mortality through the end of 2011. The study includes 357 420 participants who reported exclusively using cigar, pipes, or cigarettes or reported never using any type of tobacco product. Exposures: Current or former exclusive use of any cigar (little cigar, cigarillos, large cigar), traditional pipe, or cigarette and never tobacco use. Information on current daily and nondaily use was also collected. Estimates adjusted for age, sex, race/ethnicity, education, and survey year. Main Outcomes and Measures: All-cause and cause-specific mortality as identified as the primary cause of death from death certificate information. Results: Of the 357 420 persons included in the analysis, the majority of current and former cigar and pipe smokers were male (79.3%-98.0%), and smokers were more evenly divided by sex (46% of current daily smokers were male). There were 51 150 recorded deaths during follow-up. Exclusive current cigarette smokers (hazard ratio [HR], 1.98; 95% CI, 1.93-2.02) and exclusive current cigar smokers (HR, 1.20; 95% CI, 1.03 1.38) had higher all-cause mortality risks than never tobacco users. Exclusive current cigarette smokers (HR, 4.06; 95% CI, 3.84-4.29), exclusive current cigar smokers (HR, 1.61; 95% CI, 1.11-2.32), and exclusive current pipe smokers (HR, 1.58; 95% CI, 1.05-2.38) had an elevated risk of dying from a tobacco-related cancer (including bladder, esophagus, larynx, lung, oral cavity, and pancreas). Among current nondaily cigarette users, statistically significant associations were observed with deaths from lung cancer (HR, 6.24; 95% CI, 5.17-7.54), oral cancer (HR, 4.62; 95% CI, 1.84-11.58), circulatory death (HR, 1.43; 95% CI, 1.30 1.57), cardiovascular death (HR, 1.24; 95% CI, 1.11-1.39), cerebrovascular death (stroke) (HR, 1.39; 95% CI, 1.12-1.74), and chronic obstructive pulmonary disease (HR, 7.66; 95% CI, 6.09-9.64) as well as for daily smokers. Conclusions and Relevance: This study provides further evidence that exclusive use of cigar, pipes, and cigarettes each confers significant mortality risks.

PMID- 29459939 TI - Cognitive Outcomes of Children Born Extremely or Very Preterm Since the 1990s and Associated Risk Factors: A Meta-analysis and Meta-regression. AB - Importance: Despite apparent progress in perinatal care, children born extremely or very preterm (EP/VP) remain at high risk for cognitive deficits. Insight into factors contributing to cognitive outcome is key to improve outcomes after EP/VP birth. Objective: To examine the cognitive abilities of children of EP/VP birth (EP/VP children) and the role of perinatal and demographic risk factors. Data Sources: PubMed, Web of Science, and PsycINFO were searched without language restriction (last search March 2, 2017). Key search terms included preterm, low birth weight, and intelligence. Study Selection: Peer-reviewed studies reporting intelligence scores of EP/VP children (<32 weeks of gestation) and full-term controls at age 5 years or older, born in the antenatal corticosteroids and surfactant era, were included. A total of 268 studies met selection criteria, of which 71 covered unique cohorts. Data Extraction and Synthesis: MOOSE guidelines were followed. Data were independently extracted by 2 researchers. Standardized mean differences in intelligence per study were pooled using random-effects meta analysis. Heterogeneity in effect size across studies was studied using multivariate, random-effects meta-regression analysis. Main Outcomes and Measures: Primary outcome was intelligence. Covariates included gestational age, birth weight, birth year, age at assessment, sex, race/ethnicity, socioeconomic status, small for gestational age, intraventricular hemorrhage, periventricular leukomalacia, bronchopulmonary dysplasia (BPD), necrotizing enterocolitis, sepsis, and postnatal corticosteroid use. Results: The 71 included studies comprised 7752 EP/VP children and 5155 controls. Median gestational age was 28.5 weeks (interquartile range [IQR], 2.4 weeks) and the mean age at assessment ranged from 5.0 to 20.1 years. The median proportion of males was 50.0% (IQR, 8.7%). Preterm children had a 0.86-SD lower IQ compared with controls (95% CI, 0.94 to -0.78, P < .001). Results were heterogeneous across studies (I2 = 74.13; P < .001). This heterogeneity could not be explained by birth year of the cohort. Multivariate meta-regression analysis with backward elimination revealed that BPD explained 65% of the variance in intelligence across studies, with each percent increase in BPD rate across studies associated with a 0.01-SD decrease in IQ (0.15 IQ points) (P < .001). Conclusions and Relevance: Extremely or very preterm children born in the antenatal corticosteroids and surfactant era show large deficits in intelligence. No improvement in cognitive outcome was observed between 1990 and 2008. These findings emphasize that improving outcomes after EP/VP birth remains a major challenge. Bronchopulmonary dysplasia was found to be a crucial factor for cognitive outcome. Lowering the high incidence of BPD may be key to improving long-term outcomes after EP/VP birth.

PMID- 29459942 TI - Roles of Birth Mode and Infant Gut Microbiota in Intergenerational Transmission of Overweight and Obesity From Mother to Offspring. AB - Importance: Maternal overweight, which often results in cesarean delivery, is a strong risk factor for child overweight. Little is known about the joint contribution of birth mode and microbiota in the infant gut to the association between maternal prepregnancy overweight and child overweight. Objective: To investigate the association of birth mode with microbiota in the infant gut, and whether this mediates the association between maternal and child overweight. Design, Setting, and Participants: An observational study was conducted of 935 full-term infants born between January 1, 2009, and December 31, 2012, in the Canadian Healthy Infant Longitudinal Development (CHILD) birth cohort. Maternal prepregnancy body mass index (BMI) was calculated as weight in kilograms divided by height in meters squared using height and weight data taken from medical records or maternal report. Infant gut microbiota were profiled with 16S ribosomal RNA sequencing in fecal samples collected at a mean (SD) age of 3.7 (1.0) months. At ages 1 and 3 years, BMI z scores adjusted for age and sex were generated according to World Health Organization criteria. Statistical analysis was conducted from January 29 to June 15, 2017. Exposures: Mothers of normal weight (BMI, 18.5-24.9) and overweight or obese (BMI, >=25.0) mothers. Main Outcome and Measures: Risk of overweight and obesity (>97th percentile BMI z scores) among children at ages 1 and 3 years. Results: Of the 935 mother-infant pairs in the study (mean [SD] age, 32.5 [4.5] years) 382 (40.9%) were overweight, 69 of 926 infants (7.5%) were overweight at age 1 year, and 90 of 866 infants (10.4%) were overweight at age 3 years. Compared with being born vaginally to a mother of normal weight, infants born vaginally to overweight or obese mothers were 3 times more likely to become overweight at age 1 year (adjusted odds ratio [OR], 3.33; 95% CI, 1.49-7.41), while cesarean-delivered infants of overweight mothers had a 5-fold risk of overweight at age 1 year (adjusted OR, 5.02; 95% CI, 2.04-12.38). Similar risks were also observed at age 3 years. Multiple mediator path modeling revealed that birth mode and infant gut microbiota (Firmicutes species richness, especially of the Lachnospiraceae family) sequentially mediated the association between maternal prepregnancy overweight and childhood overweight at ages 1 and 3 years. Bacterial genera belonging to the Lachnospiraceae family were more abundant in infants of overweight mothers; however, the participating genera of Lachnospiraceae differed between infants delivered vaginally and those delivered via cesarean birth. Conclusions and Relevance: This study found evidence of a novel sequential mediator pathway involving birth mode and Firmicutes species richness (especially higher abundance of Lachnospiraceae) for the intergenerational transmission of overweight.

PMID- 29459944 TI - Association of Changes in Plasma Neurofilament Light and Tau Levels With Anesthesia and Surgery: Results From the CAPACITY and ARCADIAN Studies. AB - Importance: Anesthesia and surgery are believed to act on the central nervous system by a fully reversible mechanism innocuous to nerve cells. Evidence that neurological sequelae may follow would challenge this belief and would thereby suggest a need to reassess theories of the mechanism of anesthetic action or the response of the central nervous system to surgery. Objective: To measure 2 biomarkers of neurological injury (neurofilament light and tau) in plasma in a series of timed collections before and after anesthesia and surgery. Design, Setting, and Participants: These 2 related observational studies (CAPACITY and ARCADIAN) recruited patients 60 years and older who were undergoing general anesthesia for surgeries performed within a tertiary hospital. Blood samples were taken immediately before surgical anesthesia was administered and then sequentially after surgery at 30-minute, 6-hour, 24-hour, and 48-hour intervals. Sampling took place from January 2014 to August 2015. Data analysis took place from October 2016 to February 2017. Main Outcomes and Measures: Plasma neurofilament light and tau. Results: A total of 30 patients were enrolled (13 from the CAPACITY study and 17 from the ARCADIAN study). The mean (SD) age was 69.1 (7.0) years, and 18 members (59%) of the participant group were female; 22 (73%) were undergoing joint arthroplasty. Mean neurofilament light increased at each measurement from a combined baseline mean (SD) of 22.3 (20.4) pg/mL to a maximal combined mean (SD) level of 35.1 (28.7) pg/mL, a maximum increase of 67% (95% CI, 45%-89%; P < .001), at 48 hours postoperatively. The level of tau increased significantly from baseline at every measurement, from a combined baseline mean (SD) of 3.1 (1.3) pg/mL to a maximal combined mean (SD) of 10.8 (9.5) pg/mL, a peak increase of 257% (95% CI, 154%-361%; P < .001), at 6 hours postoperatively. After 6 hours, the mean level began to return to baseline but remained elevated after 48 hours. Conclusions and Relevance: Neurofilament light is a specific marker of axonal injury and has been shown to indicate neuronal damage in a number of diseases. Tau proteins are an integral component of axonal integrity, and increased tau indicates neuronal damage. The increases in both neurofilament light and tau over 48 hours after surgery suggest that general anesthesia and surgery may be associated with neuronal damage in the short term. Further investigations will be required to study any association with clinical outcomes. These preliminary findings demand that we question the prevailing assumption that anesthesia and surgery are innocuous, transient, and without injurious changes to the central nervous system.

PMID- 29459947 TI - Association of Vegetation Size With Embolic Risk in Patients With Infective Endocarditis: A Systematic Review and Meta-analysis. AB - Importance: Infective endocarditis is a life-threating condition with annual mortality of as much as 40% and is associated with embolic events in as many as 80% of cases. These embolic events have notable prognostic implications and have been linked to increased length of stay in intensive care units and mortality. A vegetation size greater than 10 mm has often been suggested as an optimal cutoff to estimate the risk of embolism, but the evidence is based largely on small observational studies. Objective: To study the association of vegetation size greater than 10 mm with embolic events using meta-analytic techniques. Data Sources: A computerized literature search of all publications in the PubMed and EMBASE databases from inception to May 1, 2017, was performed with search terms including varying combinations of infective endocarditis, emboli, vegetation size, pulmonary infarct, stroke, splenic emboli, renal emboli, retinal emboli, and mesenteric emboli. This search was last assessed as being up to date on May 1, 2017. Study Selection: Observational studies or randomized clinical trials that evaluated the association of vegetation size greater than 10 mm with embolic events in adult patients with infective endocarditis were included. Conference abstracts and non-English language literature were excluded. The search was conducted by 2 independent reviewers blinded to the other's work. Data Extraction and Synthesis: Following PRISMA guidelines, the 2 reviewers independently extracted data; disputes were resolved with consensus or by a third investigator. Categorical dichotomous data were summarized across treatment arms using Mantel Haenszel odds ratios (ORs) with 95% CIs. Heterogeneity of effects was evaluated using the Higgins I2 statistic. Results: The search yielded 21 unique studies published from 1983 to 2016 with a total of 6646 unique patients with infective endocarditis and 5116 vegetations with available dimensions. Patients with a vegetation size greater than 10 mm had increased odds of embolic events (OR, 2.28; 95% CI, 1.71-3.05; P < .001) and mortality (OR, 1.63; 95% CI, 1.13-2.35; P = .009) compared with those with a vegetation size less than 10 mm. Conclusions and Relevance: In this meta-analysis of 21 studies, patients with vegetation size greater than 10 mm had significantly increased odds of embolism and mortality. Understanding the risk of embolization will allow clinicians to adequately risk stratify patients and will also help facilitate discussions regarding surgery in patients with a vegetation size greater than 10 mm.

AB - Background: Treatment-free remission (TFR)-that is, stopping tyrosine kinase inhibitor (TKI) therapy without loss of response-is an emerging treatment goal in chronic myeloid leukemia (CML). Objective: To evaluate TFR after discontinuation of second-line nilotinib therapy. Design: Single-group, phase 2, open-label study. (ClinicalTrials.gov: NCT01698905). Setting: 63 centers in 18 countries. Patients: Adults with CML in chronic phase who received TKI therapy for at least 3 years (>4 weeks with imatinib, then >=2 years with nilotinib) and achieved MR4.5 (BCR-ABL1 <=0.0032% on the International Scale [BCR-ABL1IS]) while receiving nilotinib entered a 1-year consolidation phase. Those with sustained MR4.5 during consolidation were eligible to enter TFR. Interventions: Patients received nilotinib during consolidation; those who entered TFR stopped treatment. Patients with loss of major molecular response (MMR) (BCR-ABL1IS <=0.1%) or confirmed loss of MR4 (BCR-ABL1IS <=0.01%) during TFR reinitiated nilotinib treatment. Measurements: Proportion of patients without loss of MMR, confirmed loss of MR4, or treatment reinitiation within 48 weeks of stopping treatment (primary end point). Results: 163 patients who had switched from imatinib to nilotinib (for reasons including resistance, intolerance, and physician preference) enrolled in the study and entered the consolidation phase. Of these patients, 126 met the criteria for entering the TFR phase, and 73 (58% [95% CI, 49% to 67%]) and 67 (53% [CI, 44% to 62%]) maintained TFR at 48 weeks (primary end point) and 96 weeks, respectively. Of the 56 patients who reinitiated nilotinib therapy, 55 regained MMR or better and 52 regained MR4.5. None had CML progression to accelerated phase or blast crisis. Musculoskeletal pain was more frequent during the first 48 weeks after nilotinib discontinuation. Limitation: The study included a heterogeneous patient population and was not designed to compare outcomes between patients continuing and those stopping treatment. Conclusion: TFR seems achievable in patients with sustained MR4.5 after switching to nilotinib. Primary Funding Source: Novartis Pharmaceuticals Corporation.

AB - : This article has been corrected. To see what has changed, please read the Letter to the Editor and the authors' response. The original version (PDF) is appended to this article as a Supplement. Background: The Severe Sepsis and Septic Shock Early Management Bundle (SEP-1), the sepsis performance measure introduced in 2015 by the Centers for Medicare & Medicaid Services (CMS), requires the reporting of up to 5 hemodynamic interventions, as many as 141 tasks, and 3 hours to document for a single patient. Purpose: To evaluate whether moderate- or high-level evidence shows that use of the 2015 SEP-1 or its hemodynamic interventions improves survival in adults with sepsis. Data Sources: PubMed, Embase, Scopus, Web of Science, and ClinicalTrials.gov from inception to 28 November 2017 with no language restrictions. Study Selection: Randomized and observational studies of death among adults with sepsis who received versus those who did not receive either the entire SEP-1 bundle or 1 or more SEP-1 hemodynamic interventions, including serial lactate measurements; a fluid infusion of 30 mL/kg of body weight; and assessment of volume status and tissue perfusion with a focused examination, bedside cardiovascular ultrasonography, or fluid responsiveness testing. Data Extraction: Two investigators independently extracted study data and assessed each study's risk of bias; 4 authors rated level of evidence by consensus using CMS criteria published in 2013. High- or moderate-level evidence required studies to have no confounders and low risk of bias. Data Synthesis: Of 56 563 references, 20 studies (18 reports) met inclusion criteria. One single-center observational study reported lower in-hospital mortality after implementation of the SEP-1 bundle. Sixteen studies (2 randomized and 14 observational) reported increased survival with serial lactate measurements or 30-mL/kg fluid infusions. None of the 17 studies were free of confounders or at low risk of bias. In 3 randomized trials, fluid responsiveness testing did not alter survival. Limitations: Few trials, poor-quality and confounded studies, and no studies (with survival outcomes) of the focused examination or bedside cardiovascular ultrasonography. Use of the 2015 version of SEP-1 and 2013 version of CMS evidence criteria, both of which were updated in 2017. Conclusion: No high- or moderate-level evidence shows that SEP-1 or its hemodynamic interventions improve survival in adults with sepsis. Primary Funding Source: National Institutes of Health.

AB - Description: The Kidney Disease: Improving Global Outcomes (KDIGO) 2017 Clinical Practice Guideline Update for the Diagnosis, Evaluation, Prevention, and Treatment of Chronic Kidney Disease-Mineral and Bone Disorder (CKD-MBD) is a selective update of the prior CKD-MBD guideline published in 2009. The guideline update and the original publication are intended to assist practitioners caring for adults with CKD and those receiving long-term dialysis. Methods: Development of the guideline update followed an explicit process of evidence review and appraisal. The approach adopted by the Work Group and the evidence review team was based on systematic reviews of relevant trials, appraisal of the quality of the evidence, and rating of the strength of recommendations according to the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach. Searches of the English-language literature were conducted through September 2015 and were supplemented with targeted searches through February 2017. Final modification of the guidelines was informed by a public review process involving numerous stakeholders, including patients, subject matter experts, and industry and national organizations. Recommendations: The update process resulted in the revision of 15 recommendations. This synopsis focuses primarily on recommendations for diagnosis of and testing for CKD-MBD and treatment of CKD-MBD that emphasizes decreasing phosphate levels, maintaining calcium levels, and addressing elevated parathyroid hormone levels in adults with CKD stage G3a to G5 and those receiving dialysis. Key elements include basing treatment on trends in laboratory values rather than a single abnormal result and being cautious to avoid hypercalcemia when treating secondary hyperparathyroidism. PMID- 29459981 TI - Association Between Prenatal Valproate Exposure and Performance on Standardized Language and Mathematics Tests in School-aged Children. AB - Importance: Valproate sodium is used for the treatment of epilepsy and other neuropsychiatric disorders in women of childbearing potential. However, there are concerns about impaired cognitive development in children who have been exposed to valproate during pregnancy. Objective: To estimate the association between long-term school performance and prenatal exposure to valproate and a number of other antiepileptic drugs (AEDs). Design, Setting, and Participants: In a prospective, population-based cohort study conducted from August 1, 2015, to May 31, 2017, data used in the study were provided by Statistics Denmark on April 15, 2016. All children born alive in Denmark between 1997 and 2006 (n = 656 496) were identified. From this cohort, children who did not participate in the national tests, with presumed coding errors in gestational age and children missing information on their mother's educational level or household income were excluded (n = 177 469) leaving 479 027 children for the analyses. Children were identified and linked across national registers that had information on exposure, covariates, and outcome. The primary outcome was performance in national tests, an academic test taken by students in Danish primary and lower secondary state schools. We assessed performance in Danish and mathematics at different grades among valproate-exposed children and compared their performance with that of unexposed children and children exposed to another AED (lamotrigine). Test scores were standardized to z scores and adjusted for risk factors. Main Outcome and Measures: Difference in standardized z scores in Danish and mathematics tests among valproate-exposed children compared with unexposed and lamotrigine-exposed children. Results: Of the 656 496 children identified, 479 027 children who participated in the national tests were evaluated, including children exposed to the following AEDs in monotherapy: valproate, 253; phenobarbital, 86; oxcarbazepine, 236; lamotrigine, 396; clonazepam, 188; and carbamazepine, 294. The mean (SD) age of the 244 095 children completing the sixth-grade Danish test was 12.9 (0.39) years; 122 774 (50.3%; 95% CI, 50.1% to 50.5%) were boys and 121 321 (49.7%; 95% CI, 49.5% to 49.9%) were girls. Valproate-exposed children scored worse on the sixth-grade Danish tests (adjusted difference, -0.27 SD; 95% CI, 0.42 to -0.12) and sixth-grade mathematics tests (adjusted difference, -0.33 SD; (95% CI, -0.47 to -0.19) compared with unexposed children and children exposed to lamotrigine (adjusted difference, -0.33 SD; 95% CI, -0.60 to -0.06). Also, children exposed to clonazepam scored worse in the sixth-grade Danish tests (adjusted difference, -0.07 SD; 95% CI, -0.12 to -0.02). Carbamazepine, lamotrigine, phenobarbital, and oxcarbazepine were not linked to poor school performance compared with unexposed children. Conclusions and Relevance: Maternal use of valproate was associated with a significant decrease in school performance in offspring compared with children unexposed to AEDs and children exposed to lamotrigine. Findings of this study further caution against the use of valproate among women of childbearing potential. PMID- 29459982 TI - Defining Pediatric Sepsis.

An Epidemiological Timeline: A Review. AB - Importance: This article reviews the epidemiological evidence of features of alpha-synucleinopathies that precede clinical onset of disease, proposes a clinical timeline, and attempts to define the different premotor and clinical phenotypes associated with alpha-synucleinopathies. Observations: The pathological hallmarks of the alpha-synucleinopathies (Parkinson disease, Parkinson disease dementia, dementia with Lewy bodies, and multisystem atrophy) begin years before a clinical diagnosis. Epidemiologic studies support the long gap between pathology and symptoms and suggest that certain nonmotor conditions (constipation, anxiety, and rapid eye movement sleep behavior disorder) precede the traditional motor Parkinson disease phenotype by long intervals. Conclusions and Relevance: Characterizing the temporal onset of these conditions will help to better recognize the premotor phase of the alpha-synucleinopathies and specific clinical phenotypes and will guide the search for predictive biomarkers and risk or protective factors for Parkinson disease and other synucleinopathies.

PMID- 29459986 TI - Hydroxychloroquine Effectiveness in Reducing Symptoms of Hand Osteoarthritis: A Randomized Trial. AB - Background: Synovitis is believed to play a role in producing symptoms in persons with hand osteoarthritis, but data on slow-acting anti-inflammatory treatments are sparse. Objective: To determine the effectiveness of hydroxychloroquine versus placebo as an analgesic treatment of hand osteoarthritis. Design: Randomized, double-blind, placebo-controlled clinical trial with 12-month follow up. (ISRCTN registry number: ISRCTN91859104). Setting: 13 primary and secondary care centers in England. Participants: Of 316 patients screened, 248 participants (82% women; mean age, 62.7 years) with symptomatic (pain >=4 on a 0- to 10-point visual analogue scale) and radiographic hand osteoarthritis were randomly assigned and 210 (84.7%) completed the 6-month primary end point. Intervention: Hydroxychloroquine (200 to 400 mg) or placebo (1:1) for 12 months with ongoing usual care. Measurements: The primary end point was average hand pain during the previous 2 weeks (on a 0- to 10-point numerical rating scale [NRS]) at 6 months. Secondary end points included self-reported pain and function, grip strength, quality of life, radiographic structural change, and adverse events. Baseline ultrasonography was done. Results: At 6 months, mean hand pain was 5.49 points in the placebo group and 5.66 points in the hydroxychloroquine group, with a treatment difference of -0.16 point (95% CI, -0.73 to 0.40 point) (P = 0.57). Results were robust to adjustments for adherence, missing data, and use of rescue medication. No significant treatment differences existed at 3, 6, or 12 months for any secondary outcomes. The percentage of participants with at least 1 joint with synovitis was 94% (134 of 143) on grayscale ultrasonography and 59% on power Doppler. Baseline structural damage or synovitis did not affect treatment response. Fifteen serious adverse events were reported (7 in the hydroxychloroquine group [3 defined as possibly related] and 8 in the placebo group). Limitation: Hydroxychloroquine dosage restrictions may have reduced efficacy. Conclusion: Hydroxychloroquine was no more effective than placebo for pain relief in patients with moderate to severe hand pain and radiographic osteoarthritis.

The policy implications of these results for the necessary expansion of mental health services in Argentina are sufficiently great that more direct estimates of the population burdens of common mental disorders are needed. Therefore, the purpose is to present the first results regarding lifetime prevalence, projected lifetime risk up to age 75, age-of-onset, cohort effects and socio-demographic correlates of DSM-IV mental disorders among adults (18+) from the general population of urban areas of Argentina. METHOD: A multistage clustered area probability household survey was administered to 3927 individuals using the World Mental Health Composite International Diagnostic Interview. RESULTS: Lifetime prevalence of any disorder was 29.1% and projected lifetime risk at age 75 was 37.1%. Median age-of-onset of any disorder was 20 years of age. Disorders with highest lifetime prevalence were major depressive disorder (8.7%), alcohol abuse (8.1%), and specific phobia (6.8%). Anxiety disorders were the most prevalent group of disorder (16.4%) followed by mood (12.3%), substance (10.4%), and disruptive behavior disorders (2.5%). Women had greater odds of anxiety and mood disorders; men had greater odds of substance disorders. Age-at interview was inversely associated with lifetime risk of any disorder. DISCUSSION: The results provide direct evidence for high lifetime societal burdens of common mental disorders in Argentina due to a combination of high prevalence and early age-of-onset.

There is clinically sound evidence that a reduction of gait speed can be seen as an early subclinical indicator of cognitive decline of even higher risk of onset of dementia. The dual-task paradigm is a method in which the older person has to simultaneously solve two different task. It is of utmost importance to identify older persons at risk of falls or onset of dementia. The dual-task paradigm seems to be an important method in this process.

AB - About a quarter of a million people in Germany suffer a stroke every year. Stroke is the most dreaded cardiovascular disease, even before myocardial infarction and heart failure. In the last two to three years, significant progress has been made in acute treatment, secondary prophylaxis in patients with patent foramen ovale, and the interdisciplinary evaluation of atrial fibrillation as the cause of the stroke. These new findings allow for more precise treatment. PMID- 29459991 TI - [Infectious diseases - a specialty of internal medicine]. AB - Infectious diseases have recently gained wide public interest. Emerging infections and rising rates of antibiotic resistance are determining this trend. Both challenges will need to be addressed in international and local collaborations between different specialties in medicine and basic science. Infectious diseases as a clinical specialty in this scenario is directly responsible for the care of patients with infectious diseases. Its involvement in the care of patients with complicated infections has proved to be highly effective. Antibiotic stewardship programmes are effective measures in slowing the development of antibiotic resistance and have been widely implemented. But antibiotic stewardship specialists should not be confused with or taken as an alternative to infectious disease experts. Infectious diseases requires appropriate and specific training. It mainly uses the instrumentarium of internal medicine. With the current challenges in modern medicine, infectious diseases in Germany should thus be upgraded from a subspecialty to a clinical specialty, ideally within Internal Medicine. PMID- 29459993 TI - Proposal for an extended pTNM classification of thyroid carcinoma : Commentary on deficits of the 8th edition of the TNM classification. AB - In the 8th edition of the TNM classification of thyroid carcinomas, which was introduced in 2017, carcinomas with minimal extrathyroidal extension are no longer mentioned, which might cause problems. These tumors were explicitly categorized in previous TNM classifications (5-7th editions). Studies on the prognostic relevance of minimal extrathyroidal extension have shown conflicting results. Moreover, the vast majority of these studies retrospectively analyzed only subgroups of thyroid carcinomas (e.g. differentiated thyroid carcinoma, papillary thyroid carcinoma). The proposed subcategorization of the current TNM classification (8th edition) ensures the continuity of the parameter minimal extrathyroidal extension within the TNM categorization of thyroid carcinomas and also offers the possibility to prospectively analyze in a standardized manner the potential biological relevance of minimal extrathyroidal extension in relation to tumor categories (T/pT category). PMID- 29459992 TI - A systematic classification of the vertebral artery variable origin: clinical and surgical implications. AB - Several congenital anomalies regarding the right (RVA) and left (LVA) vertebral artery have been described. The current paper aims to perform a systematic literature review of the variable vertebral artery (VA) origin from the aortic arch (AOA) and its branches. The incidence of these variants and the ensuing AOA branching pattern are highlighted. Atypical origin cases were found more commonly unilaterally, while LVA presented the majority of the aberrancies. The LVA emersion from the AOA (3.6%) and the RVA from the right common carotid artery (RCCA) (0.14%) were the commonest origin variations. Aberrant RVA origin as last branch of the AOA is very rare. Eighteen cases (0.12%) with an aberrant right subclavian artery (ARSCA) were found. Among them, the RVA originated from the RCCA and right subclavian artery in 94.4 and 5.6%, respectively. Sporadic cases had an AOA origin bilaterally; RVA and LVA had a double origin in 0.027 and 0.11%, respectively. A dual origin was detected in 0.0069%, bilaterally. The atypical VA origin may coexist with: (i) an ARSCA, (ii) a common origin of brachiocephalic artery and left common carotid artery (the misnomer bovine arch) and (iii) a bicarotid trunk. The aberrant VA origin favors hemodynamic alterations, predisposing to cerebrovascular disorders and intracranial aneurysm formation. Detailed information of VA variants is crucial for both endovascular interventionists and diagnostic radiologists involved in the treatment of patients with cerebrovascular disease. Such information may prove useful to minimize the risk of VA injury in several procedures.

AB - PURPOSE: Bipolar endoscopic enucleation of the prostate (BEEP) was recommended by the 2016 EAU guidelines as the first choice of surgical treatment in men with a substantially enlarged prostate and moderate-to-severe lower urinary tract symptoms. The main aim of this study was to compare a modified diode laser enucleation of the prostate (DiLEP) to BEEP. METHODS: A total of 114 patients with prostate (20-160 mL) were randomized 1:1 into either DiLEP or BEEP in a dual centre, non-inferiority-design randomized-controlled trial. The primary outcomes included Qmax and IPSS at 12 months. Non-inferiority was evaluated by comparing the two-sided 95% CI for the mean differences of Qmax and IPSS. Secondary endpoints included other perioperative parameters, postoperative micturition variables, and complication rate. RESULTS: A total of 111 patients (97%) had completed the intent-to-treat analysis, The results showed that DiLEP was comparable to BEEP regarding Qmax (28.0 +/- 7.0 vs. 28.1 +/- 7.2 mL/s) and IPSS (3.0 +/- 2.2 vs. 2.9 +/- 2.6) at 12 months, the non-inferiority was met for both Qmax and IPSS. There were also no significant difference between two groups regarding tissue removal rate (71.8 vs. 73.8%), hemoglobin decrease (0.33 +/- 0.66 vs. 0.36 +/- 0.75 g/dL), sodium decrease (1.0 +/- 2.7 vs. 0.3 +/- 2.9 mmol/L), and Clavien III complications (5.3 vs. 1.8%) at 12 months. CONCLUSIONS: This DiLEP is an anatomical endoscopic enucleation technique for the treatment of benign prostatic hyperplasia, it is non-inferior to BEEP regarding Qmax and IPSS at 12 months postoperatively.

AB - INTRODUCTION: There is no information about the evolution of robotic programs in public hospitals of Latin-America. OBJECTIVE: To describe the current status and functioning of robotic programs in Latin-American public hospitals since their beginning to date. METHODS: We conducted a survey among leading urologists working at public hospitals of Latin-America who had acquired the Da Vinci laparoscopic-assisted robotic system. Questions included: date the program started, its utilization by other services, number and kind of surgeries, surgery paying system, surgery related deaths, occurrence and reasons of robotic program interruptions and its use for training purposes. Medians and 25-75 centiles (IQR) were estimated. RESULTS: Since 2009, there are ten public hospitals of four Latin American countries that acquired the Da Vinci robotic system. The median number of months robotic programs has been functioning without considering transitory interruption: 43 (IQR 35, 55). Median number of urologic and total surgeries performed: 140 (IQR 94, 168) and 336 (IQR 292, 621), respectively. The corresponding median number of urologic and total surgeries performed per month: 3 (IQR 2, 5) and 8 (IQR 5, 11). Median number of total surgeries performed per year per institution was 94 (IQR 68,123). The median proportion of urologic cases was 40% (IQR 31, 48), ranging from 24 to 66%. Five of ten institutions had their urology programs transitory or definitively closed due to the high burden costs. CONCLUSION: Adoption and development of robotic surgery in some public hospitals of Latin-America have been hindered by high costs. PMID- 29459997 TI - The effects of intra-arterial chemotherapy on bladder preservation in patients with T1 stage bladder cancer. AB - PURPOSE: To investigate the effects of intra-arterial chemotherapy on T1 stage bladder cancer (Bca) and evaluate patient outcome with bladder-preserving treatment approaches. MATERIALS AND METHODS: A total of 238 patients with T1 stage Bca were retrospectively analyzed. Among them, 35 patients were categorized into the subgroup of highest-risk T1 stage according to the European Association of Urology guidelines and received immediate radical cystectomy (RC group), whereas 62 were classified as being highest-risk T1 patients but were unwilling to undergo RC and were treated with gemcitabine plus cisplatin intra-arterial chemotherapy (GC group). There were 141 T1 patients who had bladder-preserving surgery with intravesical chemotherapy (IVC group). RESULTS: For patients with T1 stage Bca, the GC group had a higher estimated recurrence-free survival rate (44.4 vs. 13.9%, P = 0.087), progression-free survival rate (75.4 vs. 32.8%, P = 0.006), and cancer-specific survival (CSS) rate (78.7 vs. 67.5%, P = 0.399) when compared with the IVC group, respectively. Using the multivariable regression model, the GC intra-arterial chemotherapy was significantly related to bladder preservation (P = 0.004), lower recurrence (P = 0.012), and less progression (P = 0.004). For patients with the highest-risk T1 stage, GC group did not have a poorer CSS rate in comparison with the RC group (P = 0.383). Moreover, immediate RC did not confer a survival benefit in terms of CSS when compared with those who underwent deferred RC after failing GC intra-arterial chemotherapy (P = 0.283). CONCLUSIONS: Gemcitabine plus cisplatin intra-arterial chemotherapy may be an effective bladder-preserving alternative adjuvant treatment for patients with T1 stage Bca with oncologic benefits, good compliance, and low toxicity. PMID- 29459998 TI - Posterior-stabilized inserts are preferable to cruciate-substituting ultracongruent inserts due to more favourable kinematics and stability. AB - PURPOSE: It is unknown whether the conforming superiority of ultracongruent (UC) inserts over posterior stabilized (PS) inserts, due to an increased anterior lip for prevention of anterior displacement of the condyles during knee flexion, leads to better knee scores or greater knee stability in arthroplasty patients. This meta-analysis compared clinical outcomes, intraoperative kinematics, sagittal stability, and range of motion (ROM) between groups with either UC or PS inserts in primary total knee arthroplasty (TKA). METHODS: Studies that recorded clinical outcomes, intraoperative kinematics, sagittal stability, and ROM in patients who underwent primary TKA with UC or PS inserts were included in the meta-analysis. Subgroup analyses based on differences in flexion angles were performed for intraoperative kinematics. RESULTS: Thirteen studies met the criteria for inclusion in the meta-analysis. The UC and PS insert groups reported similar pain scores (95% CI - 0.15 to 0.16; n.s.) and function scores (95% CI - 0.30 to 0.14; n.s.). In contrast, femoral rotation during flexion (95% CI - 0.06 to 6.35; p = 0.05), posterior femoral translation during flexion (95% CI - 2.74 to - 0.15; p = 0.03), tibial sagittal laxity at 90 degrees (95% CI 2.91 to 7.72; p < 0.0001), and ROM (95% CI - 4.84 to - 1.53; p = 0.0002) differed significantly between the groups. Subgroup analyses revealed that the pooled data for femoral rotation were significantly different between groups: 60 degrees , 4.09 (p < 0.00001); 90 degrees , 7.94 (p < 0.00001); and 120 degrees , 8.16 (p < 0.00001). Furthermore, pooled data for posterior femoral translation were significantly different between groups: 90 degrees , - 3.70 (p < 0.00001); and 120 degrees , - 3.96 (p < 0.00001). CONCLUSIONS: There were no significant differences in clinical outcomes between the groups with UC and PS inserts. However, the UC insert group showed significantly greater external femoral rotation, less posterior femoral translation, greater tibial laxity in the sagittal plane, and less ROM than the PS insert group. Based on the results of the current meta analysis, in substituting the PCL, PS inserts are preferable to UC inserts due to more favourable kinematics and stability, even though both inserts have equivalent clinical outcomes. LEVEL OF EVIDENCE: Therapeutic study, Level II. PMID- 29459999 TI - Bioenergy production from sweet sorghum stalks via a biorefinery perspective. AB - Besides free sugars, sweet sorghum stalks contain cellulose and hemicellulose that can be used for biofuel production. The pretreatment of stalks without the extraction of free sugars is more complicated than typical lignocelluloses, because of the degradation of free sugars during most pretreatment processes. In this study, the bioconversion of sweet sorghum stalks into biogas and bioethanol was studied using an improved organosolv pretreatment within a biorefinery framework. The organosolv pretreatment was developed using an aqueous solution of ethanol (EtOH) and isopropanol (IPOH). The process was optimized to obtain a liquor containing free sugars with the least sugar degradations together with a highly degradable solid fraction. The liquor was subjected to anaerobic digestion for biomethane production, while the solid was used for ethanol production via simultaneous saccharification and fermentation (SSF). The most influencing pretreatment parameters, i.e., temperature, time, alcohol to water ratio, EtOH to IPOH ratio, and the presence or absence of sulfuric acid (as a catalyst), were adjusted to achieve the highest yields of bioconversion. The maximum methane and ethanol production yields of 271.2 mL CH4/g VS and 87.8% (equal to the gasoline equivalent of 0.170 and 0.241 L/kg, respectively) were achieved from the liquor and pretreated solid, respectively; however, they were obtained at different optimum conditions. Considering the biorefinery perspective, the highest gasoline equivalent of 0.249 L/kg was efficiently obtained from the whole process after pretreatment at 140 degrees C for 30 min using 60:20 EtOH/IPOH ratio in the presence of 1% sulfuric acid. Further analyses, including enzymatic adsorption/desorption, compositional analysis, FTIR, and SEM, were conducted to investigate the effects of this newly developed pretreatment on the substrate. PMID- 29460000 TI - Biotechnical production of trehalose through the trehalose synthase pathway: current status and future prospects. AB - Trehalose (alpha-D-glucopyranosyl-(1 -> 1)-alpha-D-glucopyranoside) is a non reducing disaccharide composed of two glucose molecules linked by an alpha,alpha 1,1-glycosidic bond. It possesses physicochemical properties, which account for its biological roles in a variety of prokaryotic and eukaryotic organisms and invertebrates. Intensive studies of trehalose gradually uncovered its functions, and its applications in foods, cosmetics, and pharmaceuticals have increased every year. Currently, trehalose is industrially produced by the two-enzyme method, which was first developed in 1995 using maltooligosyltrehalose synthase (EC 5.4.99.15) and subsequently using maltooligosyltrehalose trehalohydrolase (EC 3.2.1.141), with starch as the substrate. This biotechnical method has lowered the price of trehalose and expanded its applications. However, when trehalose synthase (EC 5.4.99.16) was later discovered, this method for trehalose production using maltose as the substrate soon became a popular topic because of its simplicity and potential in industrial production. Since then, many trehalose synthases have been studied. This review summarizes the sources and characteristics of reported trehalose synthases, and the most recent advances on structural analysis of trehalose synthase, catalytic mechanism, molecular modification, and usage in industrial production processes. PMID- 29460001 TI - Detection and discrimination of five E. coli pathotypes using a combinatory SYBR(r) Green qPCR screening system. AB - A detection and discrimination system for five Escherichia coli pathotypes, based on a combination of 13 SYBR(r) Green qPCR, has been developed, i.e., combinatory SYBR(r) Green qPCR screening system for pathogenic E. coli (CoSYPS Path E. coli). It allows the discrimination on isolates and the screening of potential presence in food of the following pathotypes of E. coli: shigatoxigenic (STEC) (including enterohemorrhagic (EHEC)), enteropathogenic (EPEC), enteroaggregative (EAggEC), enteroaggregative shigatoxigenic (EAggSTEC), and enteroinvasive (EIEC) E. coli. The SYBR(r) Green qPCR assays target the uidA, ipaH, eae, aggR, aaiC, stx1, and stx2 genes. uidA controls for E. coli presence and all the other genes are specific targets of E. coli pathotypes. For each gene, two primer pairs have been designed to guarantee a sufficient detection even in case of deletion or polymorphisms in the target gene. Moreover, all the qPCR have been designed to be run together in a single analytical PCR plate. This study includes the primer pairs' design, in silico and in situ selectivity, sensitivity, repeatability, and reproducibility evaluation of the 13 SYBR(r) Green qPCR assays. Each target displayed a selectivity of 100%. The limit of detection of the 13 assays is between 1 and 10 genomic copies. Their repeatability and reproducibility comply with the European requirements. As a preliminary feasibility study on food, the CoSYPS Path E. coli system was subsequently evaluated on four food matrices artificially contaminated with pathogenic E. coli. It allowed the detection of an initial contamination level as low as 2 to 7 cfu of STEC/25 g of food matrix after 24 h of enrichment. PMID- 29460002 TI - Expression of trans-membrane serine protease 3 (TMPRSS3) in the human organ of Corti. AB - TMPRSS3 (Trans-membrane Serine Protease 3) is a type II trans-membrane serine protease that has proteolytic activity essential for hearing. Mutations in the gene cause non-syndromic autosomal recessive deafness (DFNB8/10) in humans. Knowledge about its cellular distribution in the human inner ear may increase our understanding of its physiological role and involvement in deafness, ultimately leading to therapeutic interventions. In this study, we used super-resolution structured illumination microscopy for the first time together with transmission electron microscopy to localize the TMPRSS3 protein in the human organ of Corti. Archival human cochleae were dissected out during petroclival meningioma surgery. Microscopy with Zeiss LSM710 microscope achieved a lateral resolution of approximately 80 nm. TMPRSS3 was found to be associated with actin in both inner and outer hair cells. TMPRSS3 was located in cell surface-associated cytoskeletal bodies (surfoskelosomes) in inner and outer pillar cells and Deiters cells and in subcuticular organelles in outer hair cells. Our results suggest that TMPRSS3 proteolysis is linked to hair cell sterociliary mechanics and to the actin/microtubule networks that support cell motility and integrity. PMID- 29460003 TI - Detection and phylogenetic analysis of a new adenoviral polymerase gene in reptiles in Korea. AB - Over a period of 7 years (2004-2011), samples from 34 diseased reptiles provided by local governments, zoos, and pet shops were tested for viral infection. Animals were diagnosed based on clinical signs, including loss of appetite, diarrhea, rhinorrhea, and unexpected sudden death. Most of the exotic animals had gastrointestinal problems, such as mucosal redness and ulcers, while the native animals had no clinical symptoms. Viral sequences were found in seven animals. Retroviral genes were amplified from samples from five Burmese pythons (Python molurus bivittatus), an adenovirus was detected in a panther chameleon (Furcifer pardalis), and an adenovirus and a paramyxovirus were detected in a tropical girdled lizard (Cordylus tropidosternum). Phylogenetic analysis of retroviruses and paramyxoviruses showed the highest sequence identity to both a Python molurus endogenous retrovirus and a Python curtus endogenous retrovirus and to a lizard isolate, respectively. Partial sequencing of an adenoviral DNA polymerase gene from the lizard isolate suggested that the corresponding virus was a novel isolate different from the reference strain (accession no. AY576677.1). The virus was not isolated but was detected, using molecular genetic techniques, in a lizard raised in a pet shop. This animal was also coinfected with a paramyxovirus. PMID- 29460004 TI - The significance of OLGA and OLGIM staging systems in the risk assessment of gastric cancer: a systematic review and meta-analysis. AB - BACKGROUND: Despite extensive research on the criteria for the assessment of gastric cancer risk using the Operative Link on Gastritis Assessment (OLGA) and Operative Link on Gastritis/Intestinal-Metaplasia Assessment (OLGIM) systems, no comprehensive overview or systematic summary on their use is currently available. AIM: To perform a systematic review and meta-analysis to assess the efficacy of the OLGA and OLGIM staging systems in evaluating gastric cancer risk. METHODS: We searched various databases, including PubMed, EMBASE, Medline, and Cochrane's library, for articles published before March 2017 on the association between OLGA/OLGIM stages and risk of gastric cancer. Statistical analysis was performed using RevMan 5.30 and Stata 14.0, with the odds ratio, risk ratio, and 95% confidence interval as the effect measures. RESULTS: A meta-analysis of six case control studies and two cohort studies, comprising 2700 subjects, was performed. The meta-analysis of prospective case-control studies demonstrated a significant association between the OLGA/OLGIM stages III/IV and gastric cancer. The Newcastle-Ottawa Scale (NOS) score reflected heterogeneity in the case-control studies on OLGA. Subgroup analysis of high-quality (NOS score >= 5) studies showed an association between OLGA stage III/IV and increased risk of gastric cancer; the association was also high in the remaining study with low NOS score. The association between higher stages of gastritis defined by OLGA and risk of gastric cancer was significant. CONCLUSIONS: This correlation implies that close and frequent monitoring of such high-risk patients is necessary to facilitate timely diagnosis of gastric cancer. PMID- 29460005 TI - Impact of pannus formation on hemodynamic dysfunction of prosthetic aortic valve: pannus extent and its relationship to prosthetic valve motion and degree of stenosis. AB - BACKGROUND: Although pannus is an important cause of prosthetic valve dysfunction, the minimum pannus size that can induce hemodynamic dysfunction has not yet been determined. This study investigated the correlation between the limitation of motion (LOM) of the prosthetic valve and pannus extent and determined the pannus extent that could induce severe aortic stenosis. METHODS: This study included 49 patients who underwent mechanical aortic valve replacement (AVR) and showed pannus on cardiac computed tomography (CT). Pannus width, ratio of pannus width to valve diameter, pannus area, effective orifice area, encroachment ratio by pannus, pannus involvement angle and percent LOM of mechanical valves were evaluated on CT. Transvalvular peak velocity (TPV) and transvalvular pressure gradient (TPG) were measured by transesophageal echocardiography to determine the degree of aortic stenosis. The relationship between percent LOM of the prosthetic valve and pannus extent and the cut-off of pannus extent required to induce severe aortic stenosis were evaluated. RESULTS: The mean interval between AVR and pannus formation was 11 years and was longer in patients with than without severe aortic stenosis (14.0 vs. 7.3 years). On CT, the percent LOM of the prosthetic valve was significantly associated with the extent of pannus only in patients with pannus involvement angle > 180 degrees (r = 0.55-0.68, P < 0.01). Pannus width, effective orifice area, and encroachment ratio were significantly associated with increased TPV and TPG (r = 0.51-0.62, P < 0.01). Pannus width > 3.5 mm, pannus width/valve inner diameter > 0.15, and encroachment ratio > 0.14 were significantly associated with severe aortic stenosis (TPV > 4 m/s; mean TPG >= 35 mmHg), with c-indices of 0.74-079 (P < 0.005). CONCLUSION: CT-derived pannus extent parameters are good indicators of significant hemodynamic changes with increased TPV and mean TPG. PMID- 29460006 TI - Mechanical disruption of the blood-brain barrier following experimental concussion. AB - Although concussion is now recognized as a major health issue, its non-lethal nature has limited characterization of the underlying pathophysiology. In particular, potential neuropathological changes have typically been inferred from non-invasive techniques or post-mortem examinations of severe traumatic brain injury (TBI). Here, we used a swine model of head rotational acceleration based on human concussion to examine blood-brain barrier (BBB) integrity after injury in association with diffuse axonal injury and glial responses. We then determined the potential clinical relevance of the swine concussion findings through comparisons with pathological changes in human severe TBI, where post-mortem examinations are possible. At 6-72 h post-injury in swine, we observed multifocal disruption of the BBB, demonstrated by extravasation of serum proteins, fibrinogen and immunoglobulin-G, in the absence of hemorrhage or other focal pathology. BBB disruption was observed in a stereotyped distribution consistent with biomechanical insult. Specifically, extravasated serum proteins were frequently observed at interfaces between regions of tissue with differing material properties, including the gray-white boundary, periventricular and subpial regions. In addition, there was substantial overlap of BBB disruption with regions of axonal pathology in the white matter. Acute perivascular cellular uptake of blood-borne proteins was observed to be prominent in astrocytes (GFAP positive) and neurons (MAP-2-positive), but not microglia (IBA1-positive). Parallel examination of human severe TBI revealed similar patterns of serum extravasation and glial uptake of serum proteins, but to a much greater extent than in the swine model, attributed to the higher injury severity. These data suggest that BBB disruption represents a new and important pathological feature of concussion. PMID- 29460008 TI - Correction to: 12. Deutscher Wirbelsaulenkongress Jahrestagung der Deutschen Wirbelsaulengesellschaft, 30. November - 2. Dezember 2017, Stuttgart. AB - Unfortunately, the abstract from V. PMID- 29460009 TI - The Global Spine Care Initiative: applying evidence-based guidelines on the non invasive management of back and neck pain to low- and middle-income communities. AB - PURPOSE: The purpose of this review was to develop recommendations for the management of spinal disorders in low-income communities, with a focus on non invasive pharmacological and non-pharmacological therapies for non-specific low back and neck pain. METHODS: We synthesized two evidence-based clinical practice guidelines for the management of low back and neck pain. Our recommendations considered benefits, harms, quality of evidence, and costs, with attention to feasibility in medically underserved areas and low- and middle-income countries. RESULTS: Clinicians should provide education and reassurance, advise patients to remain active, and provide information about self-care options. For acute low back and neck pain without serious pathology, primary conservative treatment options are exercise, manual therapy, superficial heat, and nonsteroidal anti inflammatory drugs (NSAIDs). For patients with chronic low back and neck pain without serious pathology, primary treatment options are exercise, yoga, cognitive behavioral therapies, acupuncture, biofeedback, progressive relaxation, massage, manual therapy, interdisciplinary rehabilitation, NSAIDs, acetaminophen, and antidepressants. For patients with spinal pain with radiculopathy, clinicians may consider exercise, spinal manipulation, or NSAIDs; use of other interventions requires extrapolation from evidence regarding effectiveness for non-radicular spinal pain. Clinicians should not offer treatments that are not effective, including benzodiazepines, botulinum toxin injection, systemic corticosteroids, cervical collar, electrical muscle stimulation, short-wave diathermy, transcutaneous electrical nerve stimulation, and traction. CONCLUSION: Guidelines developed for high-income settings were adapted to inform a care pathway and model of care for medically underserved areas and low- and middle-income countries by considering factors such as costs and feasibility, in addition to benefits, harms, and the quality of underlying evidence. The selection of recommended conservative treatments must be finalized through discussion with the involved community and based on a biopsychosocial approach. Decision determinants for selecting recommended treatments include costs, availability of interventions, and cultural and patient preferences.

PMID- 29460007 TI - Diffuse gliomas classified by 1p/19q co-deletion, TERT promoter and IDH mutation status are associated with specific genetic risk loci. AB - Recent genome-wide association studies of glioma have led to the discovery of single nucleotide polymorphisms (SNPs) at 25 loci influencing risk. Gliomas are heterogeneous, hence to investigate the relationship between risk SNPs and glioma subtype we analysed 1659 tumours profiled for IDH mutation, TERT promoter mutation and 1p/19q co-deletion. These data allowed definition of five molecular subgroups of glioma: triple-positive (IDH mutated, 1p/19q co-deletion, TERT promoter mutated); TERT-IDH (IDH mutated, TERT promoter mutated, 1p/19q-wild type); IDH-only (IDH mutated, 1p/19q wild-type, TERT promoter wild-type); triple negative (IDH wild-type, 1p/19q wild-type, TERT promoter wild-type) and TERT-only (TERT promoter mutated, IDH wild-type, 1p/19q wild-type). Most glioma risk loci showed subtype specificity: (1) the 8q24.21 SNP for triple-positive glioma; (2) 5p15.33, 9p21.3, 17p13.1 and 20q13.33 SNPs for TERT-only glioma; (3) 1q44, 2q33.3, 3p14.1, 11q21, 11q23.3, 14q12, and 15q24.2 SNPs for IDH mutated glioma. To link risk SNPs to target candidate genes we analysed Hi-C and gene expression data, highlighting the potential role of IDH1 at 2q33.3, MYC at 8q24.21 and STMN3 at 20q13.33. Our observations provide further insight into the nature of susceptibility to glioma. PMID- 29460010 TI - Type V osteogenesis imperfecta undergoing surgical correction for scoliosis. AB - PURPOSE: The objective of this article is to report a case of type V osteogenesis imperfecta (OI) undergoing posterior instrumented fusion for scoliosis. Type V OI is a moderately severe dysplasia causing primary defects in endochondral bone ossification or mineralisation. It is characterised by hyperplastic callus (HPC) formation, interosseous membrane calcifications, poor bone quality and spinal deformities including scoliosis. Data on the surgical management of spinal deformities in this patient group are lacking. CASE REPORT: A 16-year-old patient with a confirmed diagnosis of type V OI presented with a progressive scoliosis. The patient underwent a T3-L4 posterior instrumented correction and fusion utilising pedicle screws, pedicle hooks and sub-laminar wiring. At 4 months after surgery, the pedicle hooks pulled out and required partial metalwork removal after CT scanning confirmed bony union and no evidence of HPC formation. The patient was successfully discharged with satisfactory correction, confirmed bony union, no neurologic complication and absence of any hyperplastic callus formation. CONCLUSION: Type V OI patients requiring surgical intervention for scoliosis correction can safely undergo posterior instrumented fusion using sublaminar wiring and pedicle hook/screw constructs without apparent risk of HPC formation around neural elements. Surgery in this patient group remains challenging due to the associated poor bone quality. LEVEL OF EVIDENCE: V. PMID- 29460012 TI - ISSLS PRIZE IN BASIC SCIENCE 2018: Growth differentiation factor-6 attenuated pro inflammatory molecular changes in the rabbit anular-puncture model and degenerated disc-induced pain generation in the rat xenograft radiculopathy model. AB - PURPOSE: To elucidate the effects of growth differentiation factor-6 (GDF6) on: (i) gene expression of inflammatory/pain-related molecules and structural integrity in the rabbit intervertebral disc (IVD) degeneration model, and (ii) sensory dysfunction and changes in pain-marker expression in dorsal nerve ganglia (DRGs) in the rat xenograft radiculopathy model. METHODS: Forty-six adolescent rabbits received anular-puncture in two non-consecutive lumbar IVDs. Four weeks later, phosphate-buffered saline (PBS) or GDF6 (1, 10 or 100 ug) was injected into the nucleus pulposus (NP) of punctured discs and followed for 4 weeks for gene expression analysis and 12 weeks for structural analyses. For pain assessment, eight rabbits were sacrificed at 4 weeks post-injection and NP tissues of injected discs were transplanted onto L5 DRGs of 16 nude rats to examine mechanical allodynia. The rat DRGs were analyzed immunohistochemically. RESULTS: In GDF6-treated rabbit NPs, gene expressions of interleukin-6, tumor necrosis factor-alpha, vascular endothelial growth factor, prostaglandin endoperoxide synthase 2, and nerve growth factor were significantly lower than those in the PBS group. GDF6 injections resulted in partial restoration of disc height and improvement of MRI disc degeneration grades with statistical significance in rabbit structural analyses. Allodynia induced by xenograft transplantation of rabbit degenerated NPs onto rat DRGs was significantly reduced by GDF6 injection. Staining intensities for ionized calcium-binding adaptor molecule-1 and calcitonin gene-related peptide in rat DRGs of the GDF6 group were significantly lower than those of the PBS group. CONCLUSION: GDF6 injection may change the pathological status of degenerative discs and attenuate degenerated IVD-induced pain. PMID- 29460011 TI - ISSLS PRIZE IN CLINICAL SCIENCE 2018: longitudinal analysis of inflammatory, psychological, and sleep-related factors following an acute low back pain episode the good, the bad, and the ugly. AB - STUDY DESIGN: Prospective longitudinal study. OBJECTIVE: To determine whether systemic cytokines and C-reactive protein (CRP) during an acute episode of low back pain (LBP) differ between individuals who did and did not recover by 6 months and to identify sub-groups based on patterns of inflammatory, psychological, and sleep features associated with recovery/non-recovery. Systemic inflammation is observed in chronic LBP and may contribute to the transition from acute to persistent LBP. Longitudinal studies are required to determine whether changes present early or develop over time. Psychological and/or sleep-related factors may be related. METHODS: Individuals within 2 weeks of onset of acute LBP (N = 109) and pain-free controls (N = 55) provided blood for assessment of CRP, tumor necrosis factor (TNF), interleukin-6 (IL-6) and interleukin-1beta, and completed questionnaires related to pain, disability, sleep, and psychological status. LBP participants repeated measurements at 6 months. Biomarkers were compared between LBP and control participants at baseline, and in longitudinal (baseline/6 months) analysis, between unrecovered (>=pain and disability), partially recovered (reduced pain and/or disability) and recovered (no pain and disability) participants at 6 months. We assessed baseline patterns of inflammatory, psychological, sleep, and pain data using hierarchical clustering and related the clusters to recovery (% change in pain) at 6 months. RESULTS: CRP was higher in acute LBP than controls at baseline. In LBP, baseline CRP was higher in the recovered than non-recovered groups. Conversely, TNF was higher at both time-points in the non-recovered than recovered groups. Two sub-groups were identified that associated with more ("inflammatory/poor sleep") or less ("high TNF/depression") recovery. CONCLUSIONS: This is the first evidence of a relationship between an "acute-phase" systemic inflammatory response and recovery at 6 months. High inflammation (CRP/IL-6) was associated with good recovery, but specific elevation of TNF, along with depressive symptoms, was associated with bad recovery. Depression and TNF may have a two-way relationship. These slides can be retrieved under Electronic Supplementary Material.

AB - PURPOSE: Studies comparing the outcome of spine surgery with that of large-joint replacement report equivocal findings. The patient-reported outcome measures (PROMs) used in such studies are typically generic and may not be sufficiently sensitive to the successes/failures of treatment. This study compared different indices of "success" in patients undergoing surgery for degenerative disorders of the lumbar spine, hip, or knee, using a validated, multidimensional, and joint specific PROM. METHODS: Preoperatively and 12 months postoperatively, 4594 patients (3937 lumbar spine, 368 hip, 269 knee) undergoing first-time surgery completed a PROM that included the Core Outcome Measures Index (COMI) for the affected joint. The latter comprises a set of single items on pain, function, symptom-specific well-being, quality of life, and disability-all in relation to the specified joint problem. Other single-item ratings of treatment success were made 12 months postoperatively. RESULTS: In multiple regression analyses, controlling for confounders, the mean improvement in COMI at 12 months was greatest for the hip patients and lowest for those with degenerative spinal deformity (= the statistical reference group) (p < 0.05). Compared with spinal deformity, the odds of achieving "success" were: higher for hip (OR 4.6; 95% CI 2.5-8.5) and knee (OR 4.0; 95% CI 2.1-7.7) (no difference between spine subgroups) for "satisfaction with care"; higher for hip (OR 16.9; 95% CI 7.3 39.6), knee (OR 6.3; 95% CI 3.4-11.6), degenerative spondylolisthesis (OR 1.6; 95% CI 1.2-2.2), and herniated disc (OR 1.7; 95% CI 1.2-2.4) for "global treatment outcome"; and higher for hip (OR 13.8; 95% CI 8.8-21.6), knee (OR 5.3; 95% CI 3.6-7.8), degenerative spondylolisthesis (OR 1.6; 95% CI 1.3-2.1), and herniated disc (1.5; 95% CI 1.1-2.0) for "patient-acceptable symptom state". Patient-rated complications were the greatest in degenerative spinal deformity (29%) and the lowest in hip (18%). CONCLUSIONS: The current study is the largest of its kind and the first to use a common, but joint-specific instrument to report patient-reported outcomes after surgery for degenerative disorders of the spine, hip, or knee. The findings provide a sobering account of the significantly poorer outcomes after spine surgery compared with large-joint replacement. Further work is required to hone the indications and patient selection criteria for spine surgery. The data should be used to lobby research funding-bodies, governmental agencies, industry, and charitable foundations to invest more in spine research/registries, in the hope of ultimately improving spine outcomes.

AB - PURPOSE: To report 4 cases undergoing 25-gauge endoscopic vitrectomy for the treatment of proliferative vitreoretinopathy with severe corneal opacity in which a transpupillary view of the fundus was not possible. STUDY DESIGN: A retrospective interventional case series. METHODS: The main outcomes measured were postoperative anatomic status of the retina and subjective improvement of vision. RESULTS: Postoperative reattachment of the retina and subjective improvement of vision were achieved in all 4 eyes. CONCLUSION: Twenty five-gauge endoscopic vitrectomy provides a clear view making it possible conduct pars plana vitrectomy in order to reattach the retina in cases of proliferative vitreoretinopathy with severe corneal opacity. PMID- 29460018 TI - Observation of neovascularization of the disc associated with proliferative diabetic retinopathy using OCT angiography. AB - PURPOSE: To describe the relationship between the vitreous and the neovascularization of the disc (NVD) using swept source optical coherence tomography (SS-OCT) and OCT angiography (OCTA). STUDY DESIGN: Retrospective. METHODS: We examined 17 eyes of 11 consecutive patients diagnosed as NVD associated with proliferative diabetic retinopathy (PDR). The location of the NVD feeder or collector vessels were examined by using RTVue XR Avanti. To determine the condition of the posterior vitreous detachment (PVD) and the proliferative tissue of the NVD, we performed 12 mm horizontal and vertical scans through the disc using SS-OCT. RESULTS: OCT images of all 17 cases indicated there was no PVD on the optic disc. OCTA showed that the locations of the newly formed vessels from the optic disc were overwhelmingly outside the physiological cupping (95%). No cases exhibited formation of neovascularization inside the physiological cupping. OCT images revealed all 17 eyes had proliferative tissues located under the posterior wall of the vitreous, with 12 out of 17 eyes exhibiting additional invasion of the proliferative tissue into the vitreous through the posterior wall. Epiretinal membrane or a thickened posterior wall of the vitreous was present in 10 out of the 17 eyes. CONCLUSIONS: NVD associated with PDR arises from outside the physiological cupping and grows along the posterior wall of the vitreous. The absence of PVD on the optic disc is essential to the growth of NVD. PMID- 29460019 TI - Association between characteristics of foveal cystoid spaces and short-term responsiveness to ranibizumab for diabetic macular edema. AB - PURPOSE: To investigate the association between the characteristics of foveal cystoid spaces and short-term responsiveness to ranibizumab treatment for diabetic macular edema (DME) at 3 months from the initial injection. METHODS: We retrospectively reviewed 66 eyes of 61 patients with center-involved DME who received three consecutive ranibizumab injections and following as-needed administrations. We evaluated the relationship between visual improvement at 3 months and the preoperative optical coherence tomography (OCT) parameters including hyperreflective foci, heterogeneous OCT reflectivity, mean levels of OCT reflectivity and height of foveal cystoid spaces. RESULTS: Twenty-three eyes without preoperative hyperreflective foci in the foveal cystoid spaces had significantly greater improvement in the logarithm of the minimum angle of resolution visual acuity (logMAR VA) at 3 months than 43 eyes with foci (P = 0.006). That was similar to the greater reduction in CSF thickness in eyes without lesions after treatment at the same time point (P < 0.001). VA improvement at 3 months was not associated with the height (R = 0.215, P = 0.083) or the reflectivity levels (R = -0.079, P = 0.538) of foveal cystoid spaces. There were no differences in VA changes between eyes with and without heterogeneous reflectivity in foveal cystoid spaces (P = 0.297). Multivariate analyses showed that logMAR VA and the absence of hyperreflective foci in foveal cystoid spaces were associated with VA improvement at 3 months. CONCLUSION: Hyperreflective foci in foveal cystoid spaces at baseline predict poorer short term responsiveness to ranibizumab injections for DME. PMID- 29460020 TI - Periodontitis May Restrain the Mandibular Bone Healing via Disturbing Osteogenic and Osteoclastic Balance. AB - Periodontitis has been advocated as a systematic chronic low-grade infection burden. However, the relationship between periodontitis and bone defect healing has not been elucidated. One hundred and eight male Wister rats were randomly assigned into three groups: control (healthy) group, periodontitis group, and periodontitis plus human tumor necrosis factor receptorII:IgG Fc fusion protein (rhTNFR:Fc) group. The experimental periodontitis model was established by ligaturing with orthodontic wire and silk suture plus local administration of 20 MUl of lipopolysaccharide (LPS). Mandibular bone defects in size of 4 * 2 * 1 mm were created for all the rats and rhTNFR:Fc subcutaneously injected at neck at a dose of 2.5 mg/kg every 3 days for the periodontitis plus rhTNFR:Fc group. The gene and protein expressions of bone-related markers in the healing tissue were monitored and new bone formation was histologically evaluated. Tartrate-resistant acid phosphatase (TRAP) staining was performed to determine the number of osteoclasts. The results showed that the mRNA and protein expressions of osteogenesis-related markers were significantly lower while nuclear factor of activated T cells, cytoplasmic 1 (NFATc1) gene expression was significantly higher in the periodontitis group. The periodontitis group showed decreased new bone formation and increased number of osteoclasts when compared to the control group. However, there was no significant difference between the periodontitis plus rhTNFR:Fc group and the control group. These results demonstrated that periodontitis may restrain the mandibular bone healing via disturbing osteogenic and osteoclastic balance in which tumor necrosis factor-alpha (TNF-alpha) could act as a leverage. PMID- 29460021 TI - The Role of TNF Family Molecules Light in Cellular Interaction Between Airway Smooth Muscle Cells and T Cells During Chronic Allergic Inflammation. AB - Interaction between T cells and airway smooth muscle (ASM) cells has been identified as an important factor in the development of asthma. LIGHT (known as TNFSF14) -mediated signaling likely contributes to various inflammatory disorders and airway remodeling. The objective of this study was to investigate the roles of LIGHT-mediated pathways in the interaction between ASM cells and T cells during chronic allergic inflammation. Mice were sensitized and challenged by ovalbumin (OVA) to induce chronic airway allergic inflammation. The control group received PBS only. The histological features and LIGHT expressions in lungs were assessed in vivo. Furthermore, T cells and ASM cells derived from the model mice were co-cultured both in the presence and absence of anti-LIGHT Ab for 72 h. The effects of LIGHT blockade on expressions of downstream signaling molecules, proliferation, and apoptosis of ASM cells, differentiation of T cells, and inflammatory cytokines release were evaluated. We demonstrated that LIGHT blockade strikingly inhibited the mRNA and protein expressions of HVEM, c-JUN, and NFkappaB. Additionally, LIGHT blockade resulted in decreased proliferation and increased apoptosis of ASM cells. Moreover, depletion of LIGHT dramatically reduced the differentiation of CD4+ T cells into Th1, Th2, and Th17 cells, as well as inhibited inflammatory cytokines release including IL-13, TGF-beta, and IFN-gamma, which are associated with CD4+ T cell differentiation and ASM cell proliferation. LIGHT plays an important role in the interaction between T cells and ASM cells in chronic allergic asthma. Blockade of LIGHT markedly suppressed ASM hyperplasia and inflammatory responses, which might be modulated through HVEM NFkappaB or c-JUN pathways. Therefore, targeting LIGHT is a promising therapeutic strategy for airway inflammation and remodeling in chronic allergic asthma.

PMID- 29460023 TI - Industry Perspective on Standardizing Food-Effect Studies for New Drug Development. AB - Investigating the effect of food on bioavailability during the development of an oral drug product is of prime importance because it has major implications on the study design of the clinical trials and dosing and administration recommendations. For modified-release formulations that exhibit dose dumping when administered with food, this may result in clinical concerns around safety and efficacy. In this article, we provide an overview of the various considerations in our opinion that impact the design and conduct of food-effect studies. We summarize the various recommendations from the different regulatory agencies and provide specific suggestions on study conduct in terms of statistical design, timing of studies, subject selection, and type and caloric content of the meal. We also discuss the role of modeling and simulation. Finally, we present an interpretation of the results of food-effect studies in addition to dosing and labeling recommendations in relation to regulatory guidance documents. PMID- 29460024 TI - Defining the optimal method for measuring baseline metabolic tumour volume in diffuse large B cell lymphoma. AB - PURPOSE: Metabolic tumour volume (MTV) is a promising prognostic indicator in diffuse large B cell lymphoma (DLBCL). Optimal thresholds to divide patients into 'low' versus 'high' MTV groups depend on clinical characteristics and the measurement method. The aim of this study was to compare in consecutive unselected patients with DLBCL, different software algorithms and published methods of MTV measurement using FDG PET. METHOD: Pretreatment MTV was measured on 147 patients treated at Guy's and St Thomas' Hospital. We compared 3 methods: SUV >=2.5, SUV >=41% of maximum SUV and SUV >= mean liver uptake (PERCIST) and compared 2 software programs for measuring SUV >=2.5; in-house 'PETTRA' software and Hermes commercial software. RESULTS: There was strong correlation between MTV using the 4 methods, although derived thresholds were very different for the 41% method. Optimal cut-offs for predicting PFS ranged from 166-400cm3. All methods predicted survival with similar accuracy. 5y-PFS was 83-87% vs. 42-44% and 5y-OS was 85-89% vs. 55-58% for the low- and high-MTV groups, respectively. Interobserver variation in 50 patients showed excellent agreement, though variation was lowest using the SUV >= 2.5 method. The 41% method was the most complex and took the longest time. CONCLUSION: All methods predicted PFS and OS with similar accuracy, but the derived cut-off separating good from poor prognosis varied markedly depending on the method. The choice of the optimal method should rely primarily on prognostic value, but for clinical use needs to take account of ease of use and reproducibility. In this study, all methods predicted prognosis, but SUV >= 2.5 had the best inter-observer agreement and was easiest to apply. PMID- 29460025 TI - Combined model-based and patient-specific dosimetry for 18F-DCFPyL, a PSMA targeted PET agent. AB - PURPOSE: Prostate-specific membrane antigen (PSMA), a type-II integral membrane protein highly expressed in prostate cancer, has been extensively used as a target for imaging and therapy. Among the available PET radiotracers, the low molecular weight agents that bind to PSMA are proving particularly effective. We present the dosimetry results for 18F-DCFPyL in nine patients with metastatic prostate cancer. METHODS: Nine patients were imaged using sequential PET/CT scans at approximately 1, 12, 35 and 70 min, and a final PET/CT scan at approximately 120 min after intravenous administration of 321 +/- 8 MBq (8.7 +/- 0.2 mCi) of18F DCFPyL. Time-integrated-activity coefficients were calculated and used as input in OLINDA/EXM software to obtain dose estimates for the majority of the major organs. The absorbed doses (AD) to the eye lens and lacrimal glands were calculated using Monte-Carlo models based on idealized anatomy combined with patient-specific volumes and activity from the PET/CT scans. Monte-Carlo based models were also developed for calculation of the dose to two major salivary glands (parotid and submandibular) using CT-based patient-specific gland volumes. RESULTS: The highest calculated mean AD per unit administered activity of 18F was found in the lacrimal glands, followed by the submandibular glands, kidneys, urinary bladder wall, and parotid glands. The S-values for the lacrimal glands to the eye lens (0.42 mGy/MBq h), the tear film to the eye lens (1.78 mGy/MBq h) and the lacrimal gland self-dose (574.10 mGy/MBq h) were calculated. Average S-values for the salivary glands were 3.58 mGy/MBq h for the parotid self-dose and 6.78 mGy/MBq h for the submandibular self-dose. The resultant mean effective dose of 18F-DCFPyL was 0.017 +/- 0.002 mSv/MBq. CONCLUSIONS: 18F-DCFPyL dosimetry in nine patients was obtained using novel models for the lacrimal and salivary glands, two organs with potentially dose-limiting uptake for therapy and diagnosis which lacked pre-existing models.

PMID- 29460027 TI - Could short thyroid hormone withdrawal be an effective strategy for radioiodine remnant ablation in differentiated thyroid cancer patients? AB - PURPOSE: Current guidelines recommend thyroid hormone withdrawal (THW) of 3-4 weeks before radioiodine remnant ablation (RRA) of differentiated thyroid carcinoma (DTC). We aimed to evaluate (1) the reliability of a shorter THW (i.e., 14 days) to achieve adequate TSH levels (i.e., 30 mU/l), (2) the association between length of THW and response to therapy, and (3) the potential association between pre-ablation TSH levels and patients' outcome. METHODS: After thyroidectomy, all patients started LT4 therapy, which was subsequently discontinued in order to perform RRA. Patients were broken down into two groups according to the length of THW: group A, 2 weeks of THW, and group B, 3-4 weeks of THW. We used clinical, biochemical, and imaging data to evaluate patients' outcome. By means of univariate and multivariate analysis, including main DTC prognostic factors, we assessed the impact of THW length and TSH levels on patients' outcome. RESULTS: We evaluated 222 patients, 85 of whom were treated with RRA after a THW period of 2 weeks (group A). All other 137 patients underwent RRA after 3-4 weeks THW (group B). At the time of RRA all patients presented TSH levels >=30 mU/l. After a median follow-up time of 3.4 years, we found 183 patients (82%) with excellent response to treatment and 39 patients (18%) showing incomplete response. Kaplan-Meier response to therapy curves showed that ablation-Tg, tumor size, and lymph node status were significantly associated with prognosis; no associations were found between THW length, TSH levels, and prognosis. Multivariate Cox model showed that only ablation-Tg was significantly associated with treatment response. CONCLUSIONS: Prior to RRA, a short 2-week THW is an effective method to stimulate TSH levels. No difference in terms of incomplete response to treatment was observed between DTC patients prepared for RRA with a short THW and those with the long THW. PMID- 29460028 TI - Hydrodynamics affect predator controls through physical and sensory stressors. AB - Predators influence communities through either consuming prey (consumptive effects, CEs) or altering prey traits (non-consumptive effects, NCEs), which has cascading effects on lower trophic levels. CEs are well known to decrease in physically stressful environments, but NCEs may be reduced at physically benign levels that affect the ability of prey to detect and respond to predators (i.e., sensory stress). We investigated the influence of physical and sensory stressors created by spatial and temporal differences in tidal flow on predator controls in a tritrophic system. We estimated mud crab reactive ranges to blue crab NCEs by evaluating mud crab CEs on juvenile oysters at different distances away from caged blue crabs across flow conditions. Mud crab reactive ranges were large at lower physical and sensory stress levels and blue crabs had a positive cascading effect on oyster survival. Blue crab NCEs were not important at higher flow conditions. Oyster survival was a complicated function of both types of stressors. Physical stress (i.e., current speed) had a positive effect on oyster survival by physically limiting mud crab CEs at high current speeds. Sensory stress (i.e., turbulence) interfered with the propagation of blue crab chemical cues used by mud crabs for predator detection, which removed blue crab NCEs. Mud crab CEs increased as a result and had a negative effect on oyster survival in turbulent conditions. Thus, environmental properties, such as fluid flow, can inflict physical and sensory stressors that have distinct effects on basal prey performance through impacts on different predator effects. PMID- 29460029 TI - Outcome of adult patients with X-linked hypophosphatemia caused by PHEX gene mutations. AB - X-linked hypophosphatemia (XLH) is the most common monogenic disorder causing hypophosphatemia. This case-note review documents the clinical features and the complications of treatment in 59 adults (19 male, 40 female) with XLH. XLH is associated with a large number of private mutations; 37 different mutations in the PHEX gene were identified in this cohort, 14 of which have not been previously reported. Orthopaedic involvement requiring surgical intervention (osteotomy) was frequent. Joint replacement and decompressive laminectomy were observed in those older than 40 years. Dental disease (63%), nephrocalcinosis (42%), and hearing impairment (14%) were also common. The rarity of the disease and the large number of variants make it difficult to discern specific genotype phenotype relationships. A new treatment, an anti-FGF23 antibody, that may affect the natural history of the disease is currently being investigated in clinical trials. PMID- 29460030 TI - Succinic semialdehyde dehydrogenase deficiency, a disorder of GABA metabolism: an update on pharmacological and enzyme-replacement therapeutic strategies. AB - We present an update to the status of research on succinic semialdehyde dehydrogenase (SSADH) deficiency (SSADHD), a rare disorder of GABA metabolism. This is an unusual disorder featuring the accumulation of both GABA and its neuromodulatory analog, gamma-hydroxybutyric acid (GHB), and recent studies have advanced the potential clinical application of NCS-382, a putative GHB receptor antagonist. Animal studies have provided proof-of-concept that enzyme replacement therapy could represent a long-term therapeutic option. The characterization of neuronal stem cells (NSCs) derived from aldehyde dehydrogenase 5a1-/- (aldh5a1-/ ) mice, the murine model of SSADHD, has highlighted NSC utility as an in vitro system in which to study therapeutics and associated toxicological properties. Gene expression analyses have revealed that transcripts encoding GABAA receptors are down-regulated and may remain largely immature in aldh5a1-/- brain, characterized by excitatory as opposed to inhibitory outputs, the latter being the expected action in the mature central nervous system. This indicates that agents altering chloride channel activity may be therapeutically relevant in SSADHD. The most recent therapeutic prospects include mTOR (mechanistic target of rapamycin) inhibitors, drugs that have received attention with the elucidation of the effects of elevated GABA on autophagy. The outlook for novel therapeutic trials in SSADHD continues to improve. PMID- 29460032 TI - Metastasis of breast cancer prior to invasion. PMID- 29460031 TI - Acute toxicity of intraoperative radiotherapy and external beam-accelerated partial breast irradiation in elderly breast cancer patients. AB - BACKGROUND AND PURPOSE: We investigated the acute toxicity of accelerated partial breast irradiation using external beam (EB-APBI) or intraoperative radiotherapy (IORT) techniques in elderly breast cancer patients. MATERIALS AND METHODS: Women >= 60 years with unifocal breast tumors of <= 30 mm were eligible for this prospective multi-center cohort study. IORT was applied with electrons following lumpectomy (23.3 Gy). EB-APBI was delivered using 3D-CRT or IMRT in 10 daily fractions of 3.85 Gy within 6 weeks after surgery. Acute toxicity was scored using the CTCAE v3.0 at 3 months after treatment. Patient-reported symptoms were analyzed using visual analogue scales (VAS) for pain and fatigue (scale 0-10), and single items from the EORTC QLQ-C30 and Breast Cancer questionnaires. RESULTS: In total, 267 (IORT) and 206 (EB-APBI) patients were available for toxicity analysis. More patients experienced >= grade 2 CTCAE acute toxicity in the IORT group (10.4% IORT and 4.9% EB-APBI; p = 0.03); grade 3 toxicity was low (3.3% IORT and 1.5% EB-APBI; ns); and no grade 4 toxicity occurred. EB-APBI patients experienced less fatigue direct postoperatively (EORTC p < 0.00, VAS p < 0.00). After 3 months only pain, according to the VAS scale, was significantly worse in the EB-APBI group (p < 0.00). CONCLUSION: Acute toxicity after IORT and EB-APBI treatment is acceptable. PMID- 29460033 TI - Factors associated with improved outcomes for metastatic inflammatory breast cancer patients. AB - PURPOSE: Controversy exists regarding the role of locoregional therapy for stage IV inflammatory breast cancer (IBC). This study aims to determine indicators of prognosis, including primary tumor resection, for stage IV IBC patients. METHODS: Using the National Cancer Data Base, female patients diagnosed 2010-2013 with unilateral a priori metastatic T4d invasive adenocarcinoma of the breast were identified. We conducted propensity score matched analysis to balance confounders of surgery versus no-surgery. Stratified log-rank test and double-robust estimation under the Cox model were used to assess the effect of surgery, and margins, on overall survival (OS) in the propensity score matched cohort. RESULTS: Of 1266 patients, 41% underwent surgery. In the unmatched cohort, median OS of the surgery and no-surgery groups was 36 and 20 months, respectively (p < 0.001). In the matched cohort (n = 588), the median OS of surgery and no-surgery groups was 29 and 27 months, respectively (p = 0.052). Patients with negative margin surgery (p = 0.024), hormone receptor-positive (p = 0.019), HER2-positive disease (p < 0.0001), treated with chemotherapy (p < 0.0001) and hormonal therapy (p < 0.0001), had better survival. Those with brain metastases had increased risk of death (p < 0.0001). CONCLUSION: This study represents the largest cohort of metastatic IBC patients, and identified negative margin surgery, systemic therapy, hormone receptor and HER2-positive disease as factors associated with improved outcomes. While these findings should be interpreted cautiously, they may be used to guide further investigations into local control and quality of life in this patient population with limited treatment options. PMID- 29460034 TI - Remembering John M. Olson (1929-2017). AB - Here we provide reflections of and a tribute to John M. Olson, a pioneering researcher in photosynthesis. We trace his career, which began at Wesleyan University and the University of Pennsylvania, and continued at Utrech in The Netherlands, Brookhaven National Laboratory, and Odense University in Denmark. He was the world expert on pigment organization in the green photosynthetic bacteria, and discovered and characterized the first chlorophyll-containing protein, which has come to be known as the Fenna-Matthews-Olson (FMO) protein. He also thought and wrote extensively on the origin and early evolution of photosynthesis. We include personal comments from Brian Matthews, Raymond Cox, Paolo Gerola, Beverly Pierson and Jon Olson. PMID- 29460035 TI - Frequent genomic alterations and better prognosis among young patients with non small-cell lung cancer aged 40 years or younger. AB - BACKGROUND: The subgroup of young patients with non-small-cell lung cancer (NSCLC) is poorly understood. We retrospectively studied the clinical characteristics, gene mutations, and outcomes of patients with NSCLC (aged <= 40 years). RESULTS: Of the 7494 patients with lung cancer diagnosed from February 2001 to October 2016, 252 aged <= 40 years showed NSCLC. We divided their cases into non-squamous cell carcinoma and squamous cell carcinoma groups according to their histology results. Of the 252 young NSCLC patients, 173 (69%) patients had stage IIIB or IV, and 196 (78%) had never smoked. The four most common metastases were intrapulmonary lesions, pleura, bone, and brain. Among patients with adenocarcinoma, 29 (40%, n = 73) harbored epidermal growth factor receptor (EGFR) mutations, 25 (34%, n = 74) harbored anaplastic lymphoma kinase (ALK) translations, and 1 (14%, n = 7) harbored ROS proto-oncogene 1 receptor tyrosine kinase (ROS1) translations. The median progression-free survival (PFS) and overall survival (OS) were 3.3 and 27.6 months for patients receiving chemotherapy (n = 65), and 12.1 and 33.6 months for patients receiving EGFR tyrosine kinase inhibitors (TKIs) (n = 13), respectively. Patients receiving crizotinib had a median PFS time of 21.9 months (n = 8). CONCLUSIONS: Young patients are associated with an increased likelihood of gene mutations and can receive a better prognosis when patients harboring gene mutations are treated with EGFR-TKIs or ALK inhibitors. PMID- 29460037 TI - Incremental rate of prefrontal oxygenation determines performance speed during cognitive Stroop test: the effect of ageing. AB - Cognitive function declines with age. The underlying mechanisms responsible for the deterioration of cognitive performance, however, remain poorly understood. We hypothesized that an incremental rate of prefrontal oxygenation during a cognitive Stroop test decreases in progress of ageing, resulting in a slowdown of cognitive performance. To test this hypothesis, we identified, using multichannel near-infrared spectroscopy, the characteristics of the oxygenated-hemoglobin concentration (Oxy-Hb) responses of the prefrontal cortex to both incongruent Stroop and congruent word-reading test. Spatial distributions of the significant changes in the three components (initial slope, peak amplitude, and area under the curve) of the Oxy-Hb response were compared between young and elderly subjects. The Stroop interference time (as a difference in total periods for executing Stroop and word-reading test, respectively) approximately doubled in elderly as compared to young subjects. The Oxy-Hb in the rostrolateral, but not caudal, prefrontal cortex increased during the Stroop test in both age groups. The initial slope of the Oxy-Hb response, rather than the peak and area under the curve, had a strong correlation with cognitive performance speed. Taken together, it is likely that the incremental rate of prefrontal oxygenation may decrease in progress of ageing, resulting in a decline in cognitive performance. PMID- 29460036 TI - The mammalian circadian system: a hierarchical multi-oscillator structure for generating circadian rhythm. AB - The circadian nature of physiology and behavior is regulated by a circadian clock that generates intrinsic rhythms with a periodicity of approximately 24 h. The mammalian circadian system is composed of a hierarchical multi-oscillator structure, with the central clock located in the suprachiasmatic nucleus (SCN) of the hypothalamus regulating the peripheral clocks found throughout the body. In the past two decades, key clock genes have been discovered in mammals and shown to be interlocked in transcriptional and translational feedback loops. At the cellular level, each cell is governed by its own independent clock; and yet, these cellular circadian clocks in the SCN form regional oscillators that are further coupled to one another to generate a single rhythm for the tissue. The oscillatory coupling within and between the regional oscillators appears to be critical for the extraordinary stability and the wide range of adaptability of the circadian clock, the mechanism of which is now being elucidated with newly advanced molecular tools.

AB - Despite impressive advancements in technological and theoretical tools, construction of phylogenetic (evolutionary) trees is still a challenging task. The availability of enormous quantities of molecular data has made large-scale phylogenetic reconstruction involving thousands of species, a more viable goal. For this goal, separate trees over different, overlapping subsets of species, representing histories of various markers of these species, are collected. These trees, typically with conflicting signals, are subsequently combined into a single tree over the full set, an operation denoted as supertree construction. The amalgamation of such trees into a single tree lies at the heart of many tasks in phylogenetics, yet remains a daunting endeavor, especially in light of conflicting signals. In this work, we study the performance of matrix representation with parsimony (MRP), the most widely used supertree method to date, when confronted with quartet trees. Quartet trees are the most basic informational unit when amalgamation of unrooted trees is attempted, and they remain relevant in more general settings even though standard supertree methods are not necessarily confined to quartets. This study involves both real and simulated data, and the effects of several parameters on the results are evaluated, revealing a number of anomalies associated with MRP. We show that these anomalies are surmountable when using a recently introduced supertree method, weighted quartet MaxCut (wQMC). PMID- 29460040 TI - Benign and malignant hepatocellular lesions in patients with vascular liver diseases. AB - A variety of vascular liver disorders can induce hepatocellular tumors. They may be related to portal venous deprivation, venous outflow obstruction, or arterial diseases. Their common feature is an imbalance between hepatic arterial and portal venous blood flow leading to an increased hepatic arterial inflow. Consequently, hepatocellular tumors may arise, most commonly focal nodular hyperplasia-like lesions but hepatocellular adenomas and hepatocellular carcinoma may be seen as well. This article will review the most common vascular liver diseases associated with hepatocellular nodules (Budd-Chiari syndrome, congenital portosystemic shunt, hereditary hemorrhagic telangiectasia, and portal cavernoma). For each condition, imaging findings will be described as well as the differential diagnosis and the diagnostic clues. PMID- 29460041 TI - Building a high-resolution T2-weighted MR-based probabilistic model of tumor occurrence in the prostate. AB - PURPOSE: We present a method for generating a T2 MR-based probabilistic model of tumor occurrence in the prostate to guide the selection of anatomical sites for targeted biopsies and serve as a diagnostic tool to aid radiological evaluation of prostate cancer. MATERIALS AND METHODS: In our study, the prostate and any radiological findings within were segmented retrospectively on 3D T2-weighted MR images of 266 subjects who underwent radical prostatectomy. Subsequent histopathological analysis determined both the ground truth and the Gleason grade of the tumors. A randomly chosen subset of 19 subjects was used to generate a multi-subject-derived prostate template. Subsequently, a cascading registration algorithm involving both affine and non-rigid B-spline transforms was used to register the prostate of every subject to the template. Corresponding transformation of radiological findings yielded a population-based probabilistic model of tumor occurrence. The quality of our probabilistic model building approach was statistically evaluated by measuring the proportion of correct placements of tumors in the prostate template, i.e., the number of tumors that maintained their anatomical location within the prostate after their transformation into the prostate template space. RESULTS: Probabilistic model built with tumors deemed clinically significant demonstrated a heterogeneous distribution of tumors, with higher likelihood of tumor occurrence at the mid gland anterior transition zone and the base-to-mid-gland posterior peripheral zones. Of 250 MR lesions analyzed, 248 maintained their original anatomical location with respect to the prostate zones after transformation to the prostate. CONCLUSION: We present a robust method for generating a probabilistic model of tumor occurrence in the prostate that could aid clinical decision making, such as selection of anatomical sites for MR-guided prostate biopsies. PMID- 29460042 TI - Spleen enlargement assessment using computed tomography: which coefficient correlates the strongest with the real volume of the spleen? AB - PURPOSE: The aim of the study was to find which linear measurements, field and volume coefficients correlate the best with real volume of the spleen and can be further used for identification of splenomegaly. METHODS: Abdominal computed tomography (CT) examinations of 264 patients were retrospectively analyzed in terms of maximal length, maximal thickness, hilum thickness, maximal height, vertical height and estimated height. Spleen volume was manually measured in Vitrea software. Two- and three-dimensional coefficients were calculated through proper mathematical formulas from linear measurements. Splenomegaly cut-off: 314.5 cm3. Data were analyzed with use of Pearson correlation and chi2 test with statistical significance at p < 0.05. RESULTS: For single measurements, the correlation with real spleen volume was the strongest for maximal height (r = 0.804; p < 0.05). Among two-dimensional indexes, multiplication product of maximal length and vertical height reached the highest level of correlation with spleen volume (r = 0.923; p < 0.05) and had the highest sensitivity and specificity (94.3% and 93.0%, respectively) for splenomegaly detection (threshold 115 cm2). In case of three-dimensional ones, the coefficient calculated from maximal length, vertical height and hilum thickness established the strongest link with spleen volume (r = 0.956; p < 0.05). CONCLUSIONS: Coefficient calculated from maximal length, vertical height and hilum thickness correlates the strongest with spleen volume and can be utilized for monitoring of spleen volume instead of obsolete splenic index. The most suitable for quick splenomegaly screening is two-dimensional coefficient (maximal length * vertical height), with the cut-off 115 cm2. PMID- 29460044 TI - MRI features of primary hepatic lymphoma. AB - PURPOSE: Our retrospective study sought to describe the spectrum of magnetic resonance imaging (MRI) features of primary hepatic lymphoma (PHL) by analyzing its morphological aspects, signal intensity before and after contrast agent (CA) administration, and diffusion-weighted imaging (DwI) with the apparent diffusion coefficient (ADC) values. METHODS: A retrospective analysis was conducted on 25 patients with pathologically proven PHL who underwent MRI between January 2011 and December 2016. For the evaluation of the ADC, we used a control group of 87 patients (22 with hepatocellular carcinoma, 15 with cholangiocellular carcinoma, 23 with liver metastasis, 22 with focal nodular hyperplasia, and 5 with adenoma). Two radiologists evaluated the morphological features, the signal intensity before and after CA administration, and the DwI. The sensitivity and specificity of the ADC values in distinguishing the PHL lesions from other hepatic lesions were calculated by analyzing the receiver operating characteristic (ROC) curves. RESULTS: Twenty-one patients had non-Hodgkin's lymphoma (18 had diffuse large B cell lymphoma and three had mucosa-associated lymphoid tissue) and four had Hodgkin's lymphoma (nodular sclerosis). The PHL had a variable morphologic distribution (17 focal mass and eight multiple nodules) and mainly an insinuative growth (24/25). Usually, PHL was usually hypointense on the T1-weighted images (23/25) and hyperintense on the T2-weighted images (21/25); non-specific dynamic enhancement was found after CA administration, but in the hepatobiliary phase, PHL is mainly hypointense (92%). All PHLs showed a signal restriction in the DwI. The sensitivity and specificity in the differential diagnosis between PHL and the other malignant lesions were respectively 81.7% and 100%, with applying an ADC cut-off value of 0.918 * 10-3 mm2/s. CONCLUSION: Although PHL is a rare disease and biopsy is still required, an MRI could be indicative. In our series, PHL showed an insinuative growth, hypointense signal in the hepatobiliary phase, signal restriction in the DwI, and an ADC value lower than that of the other hepatic lesions analyzed. PMID- 29460043 TI - Low rate of spleen involvement in sporadic Burkitt lymphoma at staging on PET-CT. AB - BACKGROUND: Burkitt lymphoma is a highly aggressive B cell non-Hodgkin lymphoma. Cross-sectional imaging techniques that are used to detect liver and spleen involvement by lymphoma have high rates of false negative and false positive findings, and as such may reduce the accuracy of staging. PURPOSE: This retrospective study evaluated the use of FDG PET-CT in determining splenic involvement at staging, in a relatively large cohort of adult patients with the sporadic form of Burkitt lymphoma (SBL). PATIENTS AND METHODS: All adult patients who underwent FDG PET-CT for staging of SBL at one medical center during 2005 2014 were enrolled for this retrospective study. RESULTS: Data were analyzed of 20 patients, with median age 49 years; 17 were male. PET-CT revealed highly intense FDG uptake, mean SUV max 11.4 +/- 7.49 (range 4.3-38) in various tissues. None of the 20 patients had either focal or diffuse increased uptake of FDG in the spleen parenchyma. In 2 patients, there were highly FDG-avid soft tissue masses adjacent to the spleen, both in the context of direct peritoneal disease extension. CONCLUSION: The spleen is rarely involved in SBL at the time of staging, according to PET-CT, except in cases with direct extension from adjacent peritoneal mass. The low rate of spleen involvement according to PET-CT may serve as a specific characteristic of SBL. Larger-scale clinical studies incorporating PET-CT scans in SBL are needed to confirm our observation. PMID- 29460045 TI - Splenic contraction: a new member of the hypovolemic shock complex. AB - OBJECTIVE: The objective of the article is to assess changes in splenic volume in the setting of hypovolemic shock; splenic enhancement in hypovolemic shock is also assessed. MATERIALS/METHODS: 71 consecutive adult patients with the hypovolemic shock complex on computed tomography (CT) were identified. Spleen volume and enhancement were compared to a baseline CT scan (without shock) or to height- and sex-corrected normal values and a control population when a comparison CT was unavailable. RESULTS: Splenic volume was significantly lower in the setting of shock. Average splenic volume in adult patients with shock was 107 +/- 63 cm3 compared to 220 +/- 164 cm3 in the control population (P < 0.001). All shock patients with a comparison CT (n = 35) had decreased splenic volume in the setting of shock. The area under the receiver operating characteristic (ROC) curve for spleen volume predicting shock was 0.83. Splenic enhancement was also significantly lower in the setting of shock. Mean splenic attenuation value in our shock population was 105 +/- 34 HU compared to 134 +/- 25 HU in the control population (P < 0.001). Decreased splenic enhancement was present in 25 of 71 shock patients and in none of the control patients (P < 0.001). CONCLUSION: Decreased splenic volume is a ubiquitous and reliable sign of hypovolemic shock and should be considered a member of the hypovolemic shock complex. It is of particular utility when a prior study is available. Splenic hypoenhancement has high specificity and a high positive predictive value for hypovolemic shock in the correct patient population. PMID- 29460046 TI - Multiparametric US for scrotal diseases. AB - Multiparametric US is increasingly recognized as a valuable problem-solving technique in scrotal pathologies. Compared to conventional Doppler modes, contrast-enhanced ultrasonography (CEUS) has higher sensitivity in assessing the presence or absence of flows, and to improve differentiation between poorly vascularized tumors and non-neoplastic, avascular lesions. Characterization of benign and malignant complex cysts is improved. In trauma patients, CEUS can help evaluating the viability of testicular parenchyma. In patients with severe epididymo-orchitis, it allows unequivocal assessment of post-inflammatory ischemic changes and abscess formation. CEUS does not add significantly to conventional Doppler modes in spermatic cord torsion. Attempt of differentiating benign and malignant tumors remains a research tool. In the clinical practice, elastography has a limited role for tumor characterization. The majority of malignant tumors are stiff at elastography, but they may display soft areas, or appear globally soft. A quantitative evaluation of testicular stiffness is feasible using shear-wave elastography. Potential clinical applications for elastographic modes could include work-up of infertile patients. PMID- 29460047 TI - Point shear wave elastography of the pancreas in patients with cystic fibrosis: a comparison with healthy controls. AB - PURPOSE: Manifestations of cystic fibrosis in the pancreas are gaining in clinical importance as patients live longer. Conventional ultrasonography and point shear wave elastography (pSWE) imaging are non-invasive and readily available diagnostic methods that are easy to perform. The aim of this study was to perform conventional ultrasonography and obtain pSWE values in the pancreases of patients with cystic fibrosis and to compare the findings with those of healthy controls. METHODS: 27 patients with cystic fibrosis (13 women/14 men; mean age 27.7 +/- 13.7 years; range 9-58 years) and 60 healthy control subjects (30 women/30 men; mean age 30.3 +/- 10.0 years; range 22-55 years) underwent examinations of the pancreas with conventional ultrasound and pSWE imaging. RESULTS: Patients with cystic fibrosis have an echogenic pancreatic parenchyma. We found cystic lesions of the pancreas in six patients. pSWE imaging of the pancreatic parenchyma gave significantly lower shear wave velocities in patients with cystic fibrosis than in the control group (1.01 m/s vs 1.30 m/s; p < 0.001). CONCLUSIONS: Using pSWE imaging in vivo, we have shown that the pancreas is considerably softer in patients with cystic fibrosis than in a healthy control population. PMID- 29460048 TI - Abdominal aortic aneurysms: pre- and post-procedural imaging. AB - Abdominal aortic aneurysm (AAA) is a relatively common, potentially life threatening disorder. Rupture of AAA is potentially catastrophic with high mortality. Intervention for AAA is indicated when the aneurysm reaches 5.0-5.5 cm or more, when symptomatic, or when increasing in size > 10 mm/year. AAA can be accurately assessed by cross-sectional imaging including computed tomography angiography and magnetic resonance angiography. Current options for intervention in AAA patients include open surgery and endovascular aneurysm repair (EVAR), with EVAR becoming more prevalent over time. Cross-sectional imaging plays a crucial role in AAA surveillance, pre-procedural assessment, and post-EVAR management. This paper will discuss the current role of imaging in the assessment of AAA patients prior to intervention, in evaluation of procedural complications, and in long-term follow-up of EVAR patients. PMID- 29460049 TI - Double Blind Study Investigating the Effect of Different Voice Prostheses on Ease of Swallowing and Residue Post Laryngectomy. AB - Voice prostheses have been examined for their effect on voice production but there is little datum on their effect on swallow function. This study investigated the difference between six commonly available voice prostheses in terms of swallowing. Laryngectomy patients had up to six voice prostheses placed in a random order over two visits. Swallowing was evaluated for each prosthesis using FEES (Fibreoptic Endoscopic Evaluation of Swallowing). After each prosthesis trial, patients self-evaluated their experience of swallowing. Three independent experts indicated which prosthesis they considered best for swallowing for each patient and judged residue on the voice prosthesis and in the upper esophagus. Raters were blinded to participant details, voice prosthesis type and scores of other raters. On patient self-evaluation, scores were equally distributed across all prostheses for swallowing. Experts most frequently chose the Blom Singer Low pressure and Blom Singer Classic Indwelling voice prostheses as best for swallowing but consensus was poor for most patients. Experts found that the Blom Singer Classic Indwelling and the Provox Vega had least residue on the voice prosthesis on thin liquid (p <= 0.001) and soft (p = 0.001), respectively. Experts also found that the Blom Singer Low Pressure had least residue in the upper esophagus on soft consistency (p <= 0.001). While self evaluation by patients did not identify a consistently preferred prosthesis for swallow, many patients expressed personal preferences, suggesting benefits to involving patients in the choice of prosthesis. Some voice prostheses may be associated with lower levels of residue on the prosthesis and upper esophagus with certain consistencies. PMID- 29460050 TI - Imaging of cytotoxic antiviral immunity while considering the 3R principle of animal research. AB - : Adoptive cell transfer approaches for antigen-specific CD8+ T cells are used widely to study their effector potential during infections or cancer. However, contemporary methodological adaptations regarding transferred cell numbers, advanced imaging, and the 3R principle of animal research have been largely omitted. Here, we introduce an improved cell transfer method that reduces the number of donor animals substantially and fulfills the requirements for intravital imaging under physiological conditions. For this, we analyzed the well established Friend retrovirus (FV) mouse model. Donor mice that expressed a FV specific T cell receptor (TCRtg) and the fluorescent protein tdTomato were used as source of antigen-specific CD8+ T cells. Only a few drops of peripheral blood were sufficient to isolate ~ 150,000 naive reporter cells from which 1000 were adoptively transferred into recently FV-infected recipients. The cells became activated and functional and expanded strongly in the spleen and bone marrow within 10 days post infection. Transferred CD8+ T cells participated in the antiviral host response within a natural range and developed an effector phenotype indistinguishable from endogenous effector CD8+ T cells. Additionally, the generated reporter cell frequency allowed single cell visualization and tracking of a physiological antiretroviral CD8+ T cell response by intravital two photon microscopy. Highly reproducible results were obtained in independent experiments by reusing the same donors repetitively for multiple transfers. Our approach allows a strong reduction of experimental animals required for studies on antigen-specific CD8+ T cell function and should be applicable to other transfer models. KEY MESSAGES: TCRtg CD8+ T cells are obtained repetitively from the blood samples of single donors. One thousand transferred TCRtg CD8+ T cells get activated, are functional, and proliferate. Several adoptive cell transfers from the same donor show reproducible results. One thousand transferred cells take part in the FV immune response without modifying it. Use of fluorescent transfer cells allows in vivo imaging and single cell tracking. PMID- 29460051 TI - Brain STAT5 signaling modulates learning and memory formation. AB - The signal transducer and activator of transcription 5 (STAT5) is a transcription factor recruited by numerous cytokines. STAT5 is important for several physiological functions, including body and tissue growth, mammary gland development, immune system and lipid metabolism. However, the role of STAT5 signaling for brain functions is still poorly investigated, especially regarding cognitive aspects. Therefore, the objective of the present study was to investigate whether brain STAT5 signaling modulates learning and memory formation. For this purpose, brain-specific STAT5 knockout (STAT5 KO) mice were studied in well-established memory tests. Initially, we confirmed a robust reduction in STAT5a and STAT5b mRNA levels in different brain structures of STAT5 KO mice. STAT5 KO mice showed no significant alterations in metabolism, growth, somatotropic axis and spontaneous locomotor activity. In contrast, brain-specific STAT5 ablation impaired learning and memory formation in the novel object recognition, Barnes maze and contextual fear conditioning tests. To unravel possible mechanisms that might underlie the memory deficits of STAT5 KO mice, we assessed neurogenesis in the hippocampus, but no significant differences were observed between groups. On the other hand, reduced insulin-like growth factor-1 (IGF-1) mRNA expression was found in the hippocampus and hypothalamus of STAT5 KO mice. These findings collectively indicate that brain STAT5 signaling is required to attain normal learning and memory. Therefore, STAT5 is an important downstream cellular mechanism shared by several cytokines to regulate cognitive functions. PMID- 29460052 TI - Dorsal raphe projection inhibits the excitatory inputs on lateral habenula and alleviates depressive behaviors in rats. AB - Hypofunction of the serotonergic (5-HT) system has close relationship with the symptoms in major depressive disorders (MDD), however, the underlying neural circuitry mechanisms are not fully understood. Lateral habenula (LHb) plays a crucial role in aversive behaviors and is activated in conditions of depression. It has been reported that 5-HT inhibits the excitability of LHb neurons, leading to the hypothesis that decreased transmission of 5-HT would elevate the activity of LHb and therefore mediates depressive symptoms. Using retrograde tract tracing with cholera toxin subunit B, we find that dorsal raphe nucleus (DRN) sends primary 5-HT projection to the LHb. In vitro slice patch-clamp recording reveals that opto-stimulation of DRN inputs to the LHb suppresses the frequency of miniature excitatory postsynaptic current, while increases paired pulse ratio in LHb neurons, indicating 5-HT projection presynaptically suppresses the excitability of LHb neurons. In chronic unpredictable mild stress (CUMS) rat model of depression, optogenetic stimulation of DRN-LHb projection alleviates the depressive symptoms in CUMS models. Meanwhile, opto-inhibition of this circuit results in elevated c-fos expression in LHb and induces depression-like behaviors. This study demonstrates that the 5-HT projection from DRN to LHb suppresses the excitability of LHb neurons, and hypofunction of 5-HT transmission induces depressive behavior via the activation of LHb. Our results reveal the functional connectivity of DRN-LHb circuit and its antidepressant action, which may provide a novel target for the treatment of depression. PMID- 29460053 TI - Extrasynaptic homomeric glycine receptors in neurons of the rat trigeminal mesencephalic nucleus. AB - The neurons in the trigeminal mesencephalic nucleus (Vmes) innervate jaw-closing muscle spindles and periodontal ligaments, and play a crucial role in the regulation of jaw movements. Recently, it was shown that many boutons that form synapses on them are immunopositive for glycine (Gly+), suggesting that these neurons receive glycinergic input. Information about the glycine receptors that mediate this input is needed to help understand the role of glycine in controlling Vmes neuron excitability. For this, we investigated the expression of glycine receptor subunit alpha 3 (GlyRalpha3) and gephyrin in neurons in Vmes and the trigeminal motor nucleus (Vmo), and the Gly+ boutons that contact them by light- and electron-microscopic immunocytochemistry and quantitative ultrastructural analysis. The somata of the Vmes neurons were immunostained for GlyRalpha3, but not gephyrin, indicating expression of homomeric GlyR. The immunostaining for GlyRalpha3 was localized away from the synapses in the Vmes neuron somata, in contrast to the Vmo neurons, where the staining for GlyRalpha3 and gephyrin were localized at the subsynaptic zones in somata and dendrites. Additionally, the ultrastructural determinants of synaptic strength, bouton volume, mitochondrial volume, and active zone area, were significantly smaller in Gly+ boutons on the Vmes neurons than in those on the Vmo neurons. These findings support the notion that the Vmes neurons receive glycinergic input via putative extrasynaptic homomeric glycine receptors, likely mediating a slow, tonic modulation of the Vmes neuron excitability. PMID- 29460054 TI - Improved urethral fluorescence during low rectal surgery: a new dye and a new method. AB - BACKGROUND: The aim of this study was to demonstrate highlighting of the urethra during surgery through the use of two different methods: a new near-infrared fluorophore IRDye800BK, and indocyanine green (ICG) mixed with silicone. METHODS: Male cadavers from the department of anatomy at the University of Oxford were used to visualise the urethra during near-infrared fluorescence excitation. To assess IRDye800BK, a perineal incision was utilised after infiltrating the urethra directly with an IRDye800BK solution mixed with Instillagel. ICG-silicone was assessed when the urethra was purposely exposed as part of a simulated transanal total mesorectal dissection. ICG was previously mixed with ethanol and silicone and left to set in a Foley catheter. Fluorescence was visualised using an in-house manufactured fluorescence-enabled laparoscopic system. RESULTS: IRDye800BK demonstrated excellent penetration and visualisation of the urethra under fluorescence at an estimated tissue depth of 2 cm. An ICG-silicone catheter demonstrated excellent fluorescence without leaving any residual solution behind in the urethra after its removal. CONCLUSIONS: The newly described ICG-silicone method opens up the possibility of new technologies in this area of fluorescence guided surgery. IRDye800BK is a promising alternative to ICG in visualising the urethra using fluorescence imaging. Its greater depth of penetration may allow earlier detection of the urethra during surgery and prevent wrong plane surgery sooner. PMID- 29460055 TI - An assessment of the risk of element contamination of urban and industrial areas using Taraxacum sect. Ruderalia as a bioindicator. AB - Central Bohemia (Czech Republic) has highly developed industry and a dense rail network. Here, we aimed to determine the content of risk elements in dandelion plants (Taraxacum sect. Ruderalia) growing near train stations, industrial enterprises, and in the city parks of 16 cities in the Central Bohemian region. The highest element contents in the soils were found in industrial areas affected by the historical mining and smelting activities; contemporary industry showed no substantial effect on the soil element contents. The median values of element contents (As, Be, Cd, Co, Cr, Cu, Ni, Pb, and Zn) at the railway station sites were the highest among the monitored sites, where the differences between park and station sites were significant for Be, Co, and Zn. Although the intensity of the traffic at the individual stations differed, we found that long-term regular traffic enhanced the element contents in the soils and, subsequently, in the plants. For Cd, Co, Cr, Cu, Pb, V, and Zn, the highest median element contents were found in plant roots, regardless of the sampling site. For Cd and Zn, the contents in leaves were higher than in the inflorescences, and the opposite pattern was recorded for Co and Cu. As and Be were distributed equally among the plant parts. Among the sampling sites, the As, Be, Cd, Zn, and Pb contents in the plant roots tended to have higher median values at the station sites, confirming the results of our soil analyses. We detected a fairly good correlation between soil and plant content for cadmium, regardless of the sampling site, soil element content, or analyzed part of the plant. Thus, we propose that dandelion is a suitable bioindicator of cadmium pollution of soil. PMID- 29460056 TI - Testicular piRNA profile comparison between successful and unsuccessful micro TESE retrieval in NOA patients. AB - PURPOSE: PIWI-interacting RNA (piRNA) is a sub-group of small RNAs about 30 nucleotides length which specifically expressed in mammalian germ cells. Although piRNAs play pivotal roles in spermatogenesis regulation, little is known in the testicular tissues of infertile men. To explore whether piRNA profile could serve as a biomarker for male infertility diagnosis in a clinic, in this study, we systematically investigated the expression profile of piRNAs in testicular tissues from the patients with non-obstructive azoospermia (NOA) between successful and unsuccessful sperm retrieval before micro-dissection testicular sperm extraction (micro-TESE). METHODS: The differential expression levels of piRNAs were evaluated using small RNA-Seq method. Ontologic analyses were performed to determine the presence of enriched biological processes. RESULTS: A total of 18,324 Homo sapiens piRNAs were identified by small RNA-Seq from NOA patient testicular tissues; among them, 959 piRNAs were significantly altered between successful and unsuccessful sperm retrieval groups, of which 951 testicular piRNAs were significantly downregulated and 8 piRNAs were upregulated in NOA patients with unsuccessful sperm retrieval (USR) groups compared to those with successful sperm retrieval (SSR) groups, respectively. Unexpectedly, 553 testicular piRNAs were found completely absent in USR but showing abundant in SSR, which suggests that those piRNAs might serve as a biomarker for micro-TESE application. A total of 20 significantly differential piRNAs (hsa-piR-20830, hsa piR-4731, hsa-piR-6254, hsa-piR-419, hsa-piR-7152, hsa-piR-7548, hsa-piR-14195, hsa-piR-5026, hsa-piR-11482, hsa-piR-17765, hsa-piR-17102, hsa-piR-4484, hsa-piR 17260, hsa-piR-17098, hsa-piR-20511, hsa-piR-5802, hsa-piR-19121, hsa-piR-2510, hsa-piR-4745, hsa-piR-11873) were selected to further validate the RNA-Seq data by quantitative real-time polymerase chain reaction. In addition, bioinformatic analyses revealed that those altered piRNAs were involved in many important biological pathways, including apoptosis, cell proliferation, and differentiation. CONCLUSIONS: Our results demonstrate that testicular tissues from NOA patients with successful and unsuccessful spermatozoa retrieval exhibit differential piRNA profiles. This study provides a useful resource to further elucidate the regulatory role of piRNAs in spermatogenesis and provides a profound clue to identify useful biomarkers for predicting residual spermatogenic loci in NOA patients during assisted reproductive treatment. PMID- 29460057 TI - What happens after no contralateral exploration in total extraperitoneal (TEP) herniorrhaphy of clinical unilateral inguinal hernias? AB - BACKGROUND: While performing unilateral TEP herniorrhaphy, controversy still exists about whether to do contralateral exploration or not. Routine contralateral exploration has been proposed to prevent metachronous contralateral hernias by the repair of incidental contralateral occult hernias. Some surgeons have even proposed to do prophylactic bilateral TEP herniorrhaphy for unilateral hernia patients. To evaluate the appropriateness of not doing contralateral exploration in unilateral TEP herniorrhaphy, we reviewed our experiences under our practice of no contralateral exploration and we also reviewed other published literature. METHODS: A total of 305 patients who underwent 313 TEP herniorrhaphies for inguinal hernias by a single surgeon during August 2012-July 2016 at Chia-Yi Christian Hospital were enrolled in this retrospective study. Demographic, perioperative and follow-up data were obtained for analysis and review. RESULTS: Of the 305 patients, 261 patients had unilateral TEP herniorrhaphy and 44 patients had bilateral TEP herniorrhaphy. The mean operation time for the unilateral TEP herniorrhaphy group was 59.8 min, and for the bilateral TEP herniorrhaphy group it was 85.2 min (p < 0.001). Seven of 261 (2.7%) patients had metachronous contralateral hernia after unilateral TEP herniorrhaphy. There were no statistically significant differences in any of the outcome variables when comparing the sequential and simultaneous primary bilateral TEP herniorrhaphies. CONCLUSIONS: Without routine contralateral exploration, the incidence of metachronous contralateral hernia was 2.7% (7/261) in unilateral hernia patients. This is acceptable as metachronous hernia also occurred in 3.2% of patients with negative contralateral exploration according to our literature review. Sequential and simultaneous bilateral primary TEP herniorrhaphy outcomes were similar. We conclude that no exploration for the other groin is a justified decision for unilateral inguinal hernia patients.

PMID- 29460058 TI - The Immunologic Paradoxes of IgG4-Related Disease. AB - IgG4-related disease (IgG4-RD), which usually occurs in middle-aged and elderly men, is a newly recognized fibroinflammatory condition characterized by swelling and sclerosis of involved organs, increased IgG4-positive plasma cell infiltration in lesions, and elevated IgG4 concentration in serum. Despite growing interest in the research, the pathophysiological mechanism remains elusive. Most IgG4-RD patients respond well to steroid therapy initially, but recurrent and refractory cases are common, especially in advanced fibrotic stage. Recent studies have documented the heterogeneity of the B cell lineages, which suggests their multiple functions in IgG4-RD beyond IgG4 production, such as cytokine secretion, antigen presentation, autoantibody production, and modulation of T and B cell interactions. Thus, a critical balance exists between pathogenic and regulatory B subsets to prevent immunopathology. A prompt response to B cell depletion therapy reported in recent cases strongly suggests the imbalance within B cell lineages in IgG4-RD. A more precise understanding of the pathogenesis of IgG4-RD will open up new perspectives for therapeutic strategy. With a particular emphasis on the novel B cell-targeted therapeutic strategies, this review highlights the immunologic features of IgG4-RD and the possible roles of B cell lineages in the pathogenesis of IgG4-RD.

AB - To control crop pests, parasitoid wasps of the genus Trichogramma are one alternative to the use of insecticides. Since a wide variety of agrochemicals may be applied to the same crops, it is essential to assess the selectivity of insecticides used for pest control on Trichogramma pretiosum. Information on which insecticides are less harmful to T. pretiosum can improve biological control using this insect, an important tactic in IPM programs for field crops. This study aimed to determine the effects of insecticides on the pupal stage and on the parasitism capacity of T. pretiosum. Lambda-cyhalothrin + thiamethoxam were slightly harmful and chlorpyriphos was moderately harmful to the pupal stage, while acephate, chlorfenapyr and flubendiamide, although considered innocuous, affected the succeeding generations of wasps, with low emergence of F1. Chlorfenapyr, chlorpyriphos and lambda-cyhalothrin + thiamethoxam reduced the parasitism, and acephate had a deleterious effect on the generation that contacted the insecticide residue. For an effective IPM program, it is important to apply selective insecticides. Further studies are needed to determine the selectivity of these insecticides under field conditions.

AB - INTRODUCTION: Craniosynostosis is the premature fusion of one or more cranial sutures. The cause of non-syndromic craniosynostosis has been attributed to a complex interaction among genetic, epigenetic, and environmental factors. Increased concordance rates in monozygotic twins support a genetic etiology while a concordance rate less than 100% suggests environmental and/or epigenetic influences. Here, we describe the first reported occurrence of all three children in a triplet set with non-syndromic single-suture craniosynostosis. CASE REPORT: The dichorionic triamniotic triplets were the product of a non-consanguineous marriage delivered at 35 weeks' gestation by a 38-year-old mother and consisted of a monochorionic-diamniotic pair (A and B) and a fraternal triplet (C). Three dimensional computed tomography scans confirmed sagittal synostosis in A and B and metopic synostosis in C. All patients underwent endoscopic strip craniectomy and were discharged on the second postoperative day with helmet orthoses. Comparative genetic hybridization (CGH) and whole-exome sequencing (WES) failed to identify pathogenic copy number variants or gene mutations, respectively. DISCUSSION AND CONCLUSION: The results of the genetic testing suggest the possibility of a rare variant contributing to the risk of midline craniosynostosis shared among the triplets, with potential modifiers at other genetic loci affecting the phenotype. We speculate mutations at loci within non coding regions not captured by our genetic analysis may have been involved. Moreover, epigenetic factors as well as environmental factors including, but not limited to, in utero head constraint could have contributed to the observed phenotype. PMID- 29460063 TI - Virtual modeling, stereolithography, and intraoperative CT guidance for the optimization of sagittal synostosis reconstruction: a technical note. AB - INTRODUCTION: Sagittal synostosis affects 1 in 1000 live births and may result in increased intracranial pressure, hindrance of normal neural development, and cosmetic deformity due to scaphocephaly. Historically, several approaches have been utilized for surgical correction and recently, computed tomography (CT) guided reconstruction procedures are increasingly used. In this report, the authors describe the use of a CT-derived virtual and stereolithographic (3D printed) craniofacial models, which are used to guide intraoperative bone placement, and intraoperative CT guidance for confirmation of bone placement, to ensure the accuracy of surgical correction of scaphocephaly, as demonstrated to parents. METHODS: Preoperative high-resolution CT imaging was used to construct 3D image sets of the skulls of two infants (a 14-month-old female and a 6-month old male) with scaphocephaly. These 3D image sets were then used to create a virtual model of the proposed surgical correction for each of the infants' deformities, which was then printed and made available for use intraoperatively to plan the bone flap, fashion the bone cuts, and optimize graft placement. After the remodeling, adherence to the preoperative plan was assessed by overlaying a CT scan of the remodeled skull with the virtual model. Deviations from the preoperative model were noted. RESULTS: Both patients had excellent postoperative cosmetic correction of head shape and contouring. The mean operative time was 5 h, blood loss was 100 ml, and one child required modification of the subocciput after intraoperative imaging showed a deviation of the reconstruction from the surgical goal as depicted by the preoperative model. CONCLUSION: The addition of neuro-navigation to stereolithographic modeling ensured the accuracy of the reconstruction for our patients and provided greater confidence to both surgeons and parents. While unisutural cases are presented for clarity, correction was still required for one patient. The cost of the models and the additional CT required must be weighed against the complexity of the procedure and possibly reserved for patients with potentially complicated corrections.

PMID- 29460065 TI - The impact of intraoperative magnetic resonance in routine pediatric neurosurgical practice-a 6-year appraisal. AB - BACKGROUND: The intraoperative magnetic resonance scanner (ioMR) was introduced in our unit in 2009, and has been used routinely since then. OBJECTIVE: This study aims to describe indications, radiological features, and clinical outcomes of the patients operated on with ioMRI and analyze our experience. METHODS: A retrospective analysis of a prospective surgical database has been performed, including surgical procedure, intent, radiological reports, need for second-look surgery, and complications, supplemented by further review of the clinical notes and the scans. RESULTS: From 2009 to 2015, 255 surgical procedures with ioMR were performed: 175 were craniotomies for tumor excision, 65 were epilepsy related, and 15 were biopsies or cyst drainages. The mean age was 9.4 years. One ioMR was performed in 79.5% patients; the mean duration of the MR was 41 min. In 172 cases (67.4%), no actions followed the ioMR. When the aim of the surgery was debulking of the tumor, the percentage of patients in which the ioMR was followed by resection was higher than when complete resection was the aim (56 vs 27.5%). The complication rate was not increased when compared with our previous results (infection 1%, neurological deficits 12%). CONCLUSION: This is the largest published series of ioMRI-aided pediatric neurosurgery to date. We have demonstrated that it can be used safely and routinely in pediatric neurosurgical procedures at any age, assisting the surgeon in achieving the best extent of resection and aiding in intra-operative decision-making for tumor- and non-tumor related intracranial pathology.

As the first country to do so, the study design used the improved EQ-5D-5L valuation protocol 2.0 developed by the EuroQol Group, including a feedback module as internal validation and a quality control process that was missing in the first wave of EQ 5D-5L valuation studies. METHODS: A representative sample of the general German population (n = 1158) was interviewed using a composite time trade-off and a discrete choice experiment under close quality control. Econometric modeling was used to estimate values for all 3125 possible health states described by EQ-5D 5L. The value set was based on a hybrid model including all available information from the composite time trade-off and discrete choice experiment valuations without any exclusions due to data issues. RESULTS: The final German value set was constructed from a combination of a conditional logit model for the discrete choice experiment data and a censored at -1 Tobit model for the composite time trade-off data, correcting for heteroskedasticity. The value set had logically consistent parameter estimates (p < 0.001 for all coefficients). The predicted EQ 5D-5L index values ranged from -0.661 to 1. CONCLUSIONS: This study provided values for the health states of the German version of EQ-5D-5L representing the preferences of the German population. The study successfully employed for the first time worldwide the improved protocol 2.0. The value set enables the use of the EQ-5D-5L instrument in economic evaluations and in clinical studies. PMID- 29460067 TI - A Systematic Review of Physical Activity Interventions in Individuals with Binge Eating Disorders. AB - PURPOSE OF REVIEW: Our systematic review aims to assess the overall evidence available in the literature regarding the role of physical activity (PA) in individuals with binge eating disorder (BED) and better understand the potential underlying mechanisms of action. RECENT FINDINGS: Currently, the most effective and well-established psychological treatment for BED is cognitive behavioral therapy (CBT) with a remission rate around 80%. CBT is sometimes combined with pharmacotherapy targeting comorbidities associated with BED, such as obesity and depression. Another avenue of treatment that has been less studied is PA. It has been suggested that PA addresses the underlying mechanisms of BED and, thus, increases treatment efficiency. This systematic review provides additional knowledge concerning the benefits of PA in the treatment of individuals with BED including reduction of binge eating (BE) episodes and improvement in other associated comorbidities. Potential mechanisms of action of PA include neurochemical alterations affecting the reward system, reduction of negative affect, and its anorexigenic effects. PMID- 29460068 TI - Decanethiol functionalized silver nanoparticles are new powerful leishmanicidals in vitro. AB - We evaluated, for the first time, the leishmanicidal potential of decanethiol functionalized silver nanoparticles (AgNps-SCH) on promastigotes and amastigotes of different strains and species of Leishmania: L. mexicana and L. major isolated from different patients suffering from localized cutaneous leishmaniasis (CL) and L. mexicana isolated from a patient suffering from diffuse cutaneous leishmaniasis (DCL). We recorded the kinetics of promastigote growth by daily parasite counting for 5 days, promastigote mobility, parasite reproduction by CFSE staining's protocol and promastigote killing using the propidium iodide assay. We also recorded IC50's of promastigotes and amastigotes, therapeutic index, and cytotoxicity by co-culturing macrophages with AgNps-SCH or sodium stibogluconate (Sb) used as reference drug. We used Sb as a reference drug since it is used as the first line treatment for all different types of leishmaniasis. At concentrations 10,000 times lower than those used with Sb, AgNps-SCH had a remarkable leishmanicidal effect in all tested strains of parasites and there was no toxicity to J774A.1 macrophages since > 85% were viable at the concentrations used. Therapeutic index was about 20,000 fold greater than the corresponding one for Sb treated cells. AgNps-SCH inhibited > 80% promastigote proliferation in all tested parasites. These results demonstrate there is a high leishmanicidal potential of AgNps-SCH at concentrations of 0.04 uM. Although more studies are needed, including in vivo testing of AgNps-SCH against different types of leishmaniasis, they can be considered a potential new treatment alternative. PMID- 29460069 TI - Experimental feasibility of spectral photon-counting computed tomography with two contrast agents for the detection of endoleaks following endovascular aortic repair. AB - OBJECTIVES: After endovascular aortic repair (EVAR), discrimination of endoleaks and intra-aneurysmatic calcifications within the aneurysm often requires multiphase computed tomography (CT). Spectral photon-counting CT (SPCCT) in combination with a two-contrast agent injection protocol may provide reliable detection of endoleaks with a single CT acquisition. METHODS: To evaluate the feasibility of SPCCT, the stent-lined compartment of an abdominal aortic aneurysm phantom was filled with a mixture of iodine and gadolinium mimicking enhanced blood. To represent endoleaks of different flow rates, the adjacent compartments contained either one of the contrast agents or calcium chloride to mimic intra aneurysmatic calcifications. After data acquisition with a SPCCT prototype scanner with multi-energy bins, material decomposition was performed to generate iodine, gadolinium and calcium maps. RESULTS: In a conventional CT slice, Hounsfield units (HU) of the compartments were similar ranging from 147 to 168 HU. Material-specific maps differentiate the distributions within the compartments filled with iodine, gadolinium or calcium. CONCLUSION: SPCCT may replace multiphase CT to detect endoleaks without sacrificing diagnostic accuracy. It is a unique feature of our method to capture endoleak dynamics and allow reliable distinction from intra-aneurysmatic calcifications in a single scan, thereby enabling a significant reduction of radiation exposure. KEY POINTS: * SPCCT might enable advanced endoleak detection. * Material maps derived from SPCCT can differentiate iodine, gadolinium and calcium. * SPCCT may potentially reduce radiation burden for EVAR patients under post-interventional surveillance. PMID- 29460070 TI - Comparison of image quality and radiation dose between split-filter dual-energy images and single-energy images in single-source abdominal CT. AB - OBJECTIVES: To compare image quality and radiation dose of abdominal split-filter dual-energy CT (SF-DECT) combined with monoenergetic imaging to single-energy CT (SECT) with automatic tube voltage selection (ATVS). METHODS: Two-hundred single source abdominal CT scans were performed as SECT with ATVS (n = 100) and SF-DECT (n = 100). SF-DECT scans were reconstructed and subdivided into composed images (SF-CI) and monoenergetic images at 55 keV (SF-MI). Objective and subjective image quality were compared among single-energy images (SEI), SF-CI and SF-MI. CNR and FOM were separately calculated for the liver (e.g. CNRliv) and the portal vein (CNRpv). Radiation dose was compared using size-specific dose estimate (SSDE). Results of the three groups were compared using non-parametric tests. RESULTS: Image noise of SF-CI was 18% lower compared to SEI and 48% lower compared to SF-MI (p < 0.001). Composed images yielded higher CNRliv over single energy images (23.4 vs. 20.9; p < 0.001), whereas CNRpv was significantly lower (3.5 vs. 5.2; p < 0.001). Monoenergetic images overcame this inferiority in CNRpv and achieved similar results compared to single-energy images (5.1 vs. 5.2; p > 0.628). Subjective sharpness was equal between single-energy and monoenergetic images and diagnostic confidence was equal between single-energy and composed images. FOMliv was highest for SF-CI. FOMpv was equal for SEI and SF-MI (p = 0.78). SSDE was significant lower for SF-DECT compared to SECT (p < 0.022). CONCLUSIONS: The combined use of split-filter dual-energy CT images provides comparable objective and subjective image quality at lower radiation dose compared to single-energy CT with ATVS. KEY POINTS: * Split-filter dual-energy results in 18% lower noise compared to single-energy with ATVS. * Split-filter dual-energy results in 11% lower SSDE compared to single-energy with ATVS. * Spectral shaping of split-filter dual-energy leads to an increased dose efficiency. PMID- 29460071 TI - Transjugular intrahepatic portosystemic shunt creation: three-dimensional roadmap versus CO2 wedged hepatic venography. AB - OBJECTIVES: The blind portal vein puncture remains the most challenging step during transjugular intrahepatic portosystemic shunt (TIPS) creation. We performed a prospective randomised clinical trial to compare three-dimensional (3D) roadmap with CO2 wedged hepatic vein portography for portal vein puncture guidance. METHODS: Between March 2017 and May 2017, 30 patients were enrolled and randomly allocated to the study group (3D roadmap) or the control group (CO2 wedged hepatic vein portography). RESULTS: Technical success of TIPS procedures was achieved in all 30 patients. The mean number of needle passes was significantly lower in the study group (2.0 +/- 1.0) compared to the control group (3.7 +/- 2.5; p = 0.021). A total of six (40%) patients in the study group and three (20%) in the control group required only one puncture for the establishment of TIPS. There were no significant differences in total fluoroscopy time (p = 0.905), total procedure time (p = 0.199) and dose-area product (p = 0.870) between the two groups. CONCLUSIONS: 3D roadmap is a safe and technically feasible means for portal vein puncture guidance during TIPS creation, equivalent in efficacy to CO2 wedged hepatic vein portography. This technique could reduce the number of needle passes, thereby simplifying the TIPS procedure. KEY POINTS: * 3D roadmap can be used to guide portal vein puncture. * Compared with CO 2 venography, 3D roadmap reduced the number of needle passes. * 3D roadmap has a potential to simplify the TIPS procedure. PMID- 29460072 TI - New MRI muscle classification systems and associations with return to sport after acute hamstring injuries: a prospective study. AB - OBJECTIVES: To determine agreement between modified Peetrons, Chan acute muscle strain injury classification and British Athletics Muscle Injury Classification (BAMIC) and to investigate their associations and ability to predict time to return to sport (RTS). METHODS: Male athletes (n=176) with acute hamstring injury and MRI (1.5T) <=5 days were followed until RTS. MRIs were scored using standardised forms. RESULTS: For MRI-positive injuries there was moderate agreement in severity grading (kappa = 0.50-0.56). Substantial variance in RTS was demonstrated within and between MRI categories. Mean differences showed an overall main effect for severity grading (p < 0.001), but post hoc pairwise comparisons for BAMIC (grade 0a/b vs. 1, p = 0.312; 1 vs 2, p = 0.054; 0a/b vs 2, p < 0.001; 1 vs 3, p < 0.001) and mean differences for anatomical sites (BAMIC a c, p < 0.001 [a vs b, p = 0.974; a vs c, p = 0.065; b vs c, p = 0.007]; Chan anatomical sites 1-5, p < 0.077; 2A-C, p = 0.373; 2a-e, p = 0.008; combined BAMIC, p < 0.001) varied. For MRI-positive injuries, total explained RTS variance was 7.6-11.9% for severity grading and BAMIC anatomical sites. CONCLUSIONS: There was wide overlap between/variation within the grading/classification categories. Therefore, none of the classification systems could be used to predict RTS in our sample of MRI-positive hamstring injuries. KEY POINTS: * Days to RTS varied greatly within the grading and classification categories. * Days to RTS varied greatly between the grading and classification categories. * Using MRI classification systems alone to predict RTS cannot be recommended. * The specific MRI classification used should be reported to avoid miscommunication. PMID- 29460073 TI - Progressive supranuclear palsy and idiopathic Parkinson's disease are associated with local reduction of in vivo brain viscoelasticity. AB - OBJECTIVES: To apply three-dimensional multifrequency MR-elastography (3DMRE) for the measurement of local cerebral viscoelasticity changes in patients with Parkinson's disease (PD) and progressive supranuclear palsy (PSP). METHODS: T1 weighted anatomical imaging and 3DMRE were performed in 17 PD and 20 PSP patients as well as 12 controls. Two independent viscoelasticity parameters, |G*| and phi, were reconstructed combining seven harmonic vibration frequencies (30-60 Hz). Spatially averaged values were compared by one-way ANOVA, groups were compared using unpaired t test and Mann-Whitney test, respectively. Correlation between clinical data and parameters of brain elasticity and volume were calculated by Pearson's correlation coefficient. RESULTS: In patients, |G*| was significantly reduced in the frontal and mesencephalic regions (p < 0.05). Beyond that, reduced mesencephalic |G*| discriminated PSP from PD (p < 0.05). Neurodegeneration causes significant brain atrophy (p < 0.01) and is pronounced in PSP patients (p < 0.05 vs. PD). Reduced brain viscoelasticity is correlated with brain atrophy in PSP (r=0.64, p=0.002) and PD (r=0.65, p=0.005) patients but not in controls. CONCLUSIONS: MRE-measured viscoelasticity reflects local structural changes of brain tissue in PSP and in PD and provides a useful parameter to differentiate neurodegenerative movement disorders based on imaging examinations. KEY POINTS: * 3D multifrequency MR-elastography reveals diffuse regional changes in brain viscoelasticity in neurodegenerative disorders. * Reduced mesencephalic viscoelasticity separates PD and PSP. * Reduced brain viscoelasticity and brain atrophy as independent hallmarks of neurodegeneration hypothesized. PMID- 29460074 TI - The role of breast tomosynthesis in a predominantly dense breast population at a tertiary breast centre: breast density assessment and diagnostic performance in comparison with MRI. AB - OBJECTIVES: To compare breast density measured on digital breast tomosynthesis (DBT) (BI-RADS-based breast composition and fully-automatic estimation) and magnetic resonance imaging (MRI) (BI-RADS amount of fibroglandular tissue), and to evaluate the diagnostic performance in terms of sensitivity and specificity of DBT and MRI in a predominantly dense breast population. METHODS: Between 2015 and 2016, 152 women with 103 breast malignancies, who underwent 3-T breast MRI and DBT within 2 months' time, were enrolled in this study. Breast composition/fibroglandular tissue and findings on DBT (two readers) and MRI were reported using BI-RADS 5th edition. Digital mammography images were analysed for breast percent density (PD) using the Libra software tool. RESULTS: A majority of women had dense breasts as categorised by breast composition c (heterogeneously dense) (68%) and d (extremely dense) (15%). The mean PD was 44% (range, 18-89%) and the correlation between breast composition and PD was r = 0.6. The diagnostic performance of MRI was significantly higher compared to DBT for one reader as described by the area under the receiver operating characteristic (ROC) curve (p = 0.004) and of borderline significance for the other reader (p = 0.052). CONCLUSIONS: MRI had higher diagnostic performance than DBT in a dense breast population in the tertiary setting. KEY POINTS: * MRI had higher diagnostic performance than DBT in a dense breast population * Diagnostic performance of DBT was comparable to MRI in women with fatty breasts * MRI was superior to DBT in preoperative breast cancer size assessment. PMID- 29460075 TI - A noise-optimized virtual monoenergetic reconstruction algorithm improves the diagnostic accuracy of late hepatic arterial phase dual-energy CT for the detection of hypervascular liver lesions. AB - OBJECTIVES: To assess the image quality and diagnostic accuracy of a noise optimized virtual monoenergetic imaging (VMI+) algorithm compared with standard virtual monoenergetic imaging (VMI) and linearly-blended (M_0.6) reconstructions for the detection of hypervascular liver lesions in dual-energy CT (DECT). METHODS: Thirty patients who underwent clinical liver MRI were prospectively enrolled. Within 60 days of MRI, arterial phase DECT images were acquired on a third-generation dual-source CT and reconstructed with M_0.6, VMI and VMI+ algorithms from 40 to 100 keV in 5-keV intervals. Liver parenchyma and lesion contrast-to-noise-ratios (CNR) were calculated. Two radiologists assessed image quality. Lesion sensitivity, specificity and area under the receiver operating characteristic curves (AUCs) were calculated for the three algorithms with MRI as the reference standard. RESULTS: VMI+ datasets from 40 to 60 keV provided the highest liver parenchyma and lesion CNR (p <=0.021); 50 keV VMI+ provided the highest subjective image quality (4.40+/-0.54), significantly higher compared to VMI and M_0.6 (all p <0.001), and the best diagnostic accuracy in < 1-cm diameter lesions (AUC=0.833 vs. 0.777 and 0.749, respectively; p <=0.003). CONCLUSIONS: 50 keV VMI+ provides superior image quality and diagnostic accuracy for the detection of hypervascular liver lesions with a diameter < 1cm compared to VMI or M_0.6 reconstructions. KEY POINTS: * Low-keV VMI+ are characterized by higher contrast resulting from maximum iodine attenuation. * VMI+ provides superior image quality compared with VMI or M_0.6. * 50-keV_VMI+ provides higher accuracy for the detection of hypervascular liver lesions < 1cm. PMID- 29460077 TI - Orofacial antinociceptive effect of sulphated polysaccharide from the marine algae Hypnea pseudomusciformis in rodents. AB - This study aimed to evaluate the antinociceptive effect of sulphated polysaccharide from the marine algae Hypnea pseudomusciformis (PLS) using rodent models of orofacial pain. Acute pain was induced by formalin, capsaicin, cinnamaldehyde, acidified saline or glutamate (cutaneous modes) and hypertonic saline (corneal model). In one experiment, animals were pretreated with ruthenium red, glibenclamide, naloxone, L-NAME, methylene blue or ketamine to investigate the mechanism of antinociception. In another experiment, animals pretreated with PLS or saline were submitted to the temporomandibular joint formalin test. In yet another, animals were submitted to craniofacial pain induced by mustard oil. Motor activity was evaluated with the open-field test. Cytotoxicity and antioxidant activities were also assessed. Pre-treatment with PLS significantly reduced nociceptive behavior associated with acute pain. Antinociception was effectively reduced, but not inhibited, by ruthenium red and ketamine. L-NAME and glibenclamide enhanced the PLS effect. PLS antinociception was resistant to methylene blue, naloxone and heating. PLS presented no cytotoxicity or antioxidant properties. Our results confirm the potential pharmacological relevance of PLS as an inhibitor of orofacial nociception in acute pain probably mediated by glutamatergic, nitrergic, TRPs and K + ATP pathways. PMID- 29460076 TI - Visual grading analysis of digital neonatal chest phantom X-ray images: Impact of detector type, dose and image processing on image quality. AB - OBJECTIVES: To evaluate the impact of digital detector, dose level and post processing on neonatal chest phantom X-ray image quality (IQ). METHODS: A neonatal phantom was imaged using four different detectors: a CR powder phosphor (PIP), a CR needle phosphor (NIP) and two wireless CsI DR detectors (DXD and DRX). Five different dose levels were studied for each detector and two post processing algorithms evaluated for each vendor. Three paediatric radiologists scored the images using European quality criteria plus additional questions on vascular lines, noise and disease simulation. Visual grading characteristics and ordinal regression statistics were used to evaluate the effect of detector type, post-processing and dose on VGA score (VGAS). RESULTS: No significant differences were found between the NIP, DXD and CRX detectors (p>0.05) whereas the PIP detector had significantly lower VGAS (p< 0.0001). Processing did not influence VGAS (p=0.819). Increasing dose resulted in significantly higher VGAS (p<0.0001). Visual grading analysis (VGA) identified a detector air kerma/image (DAK/image) of ~2.4 MUGy as an ideal working point for NIP, DXD and DRX detectors. CONCLUSIONS: VGAS tracked IQ differences between detectors and dose levels but not image post-processing changes. VGA showed a DAK/image value above which perceived IQ did not improve, potentially useful for commissioning. KEY POINTS: * A VGA study detects IQ differences between detectors and dose levels. * The NIP detector matched the VGAS of the CsI DR detectors. * VGA data are useful in setting initial detector air kerma level. * Differences in NNPS were consistent with changes in VGAS.

AB - The tropical herb Labisia pumila is traditionally used in facilitating childbirth and post-partum care. The effects of L. pumila leaf extract (LP) in explant cartilage culture and on postmenopausal osteoarthritis (OA) rat model were assessed. The LP (10, 25 and 50 ug/ml) or diclofenac (10 ug/ml) was added to the cartilage explants containing bovine IL-1beta (20 ng/ml), to evaluate their direct effects on cartilage degradation. In the preclinical study, rats were grouped (n = 8) into: non-treated OA; OA + diclofenac (5 mg/kg); OA + LP extract (150 and 300 mg/kg); and healthy control. To induce OA, monosodium iodoacetate was injected into the ovariectomised female rats' intra-articular knee joints and evaluated for OA severity after 8 weeks via physical (radiological, macroscopic and histological observations), biochemical, ELISA and mRNA expression analysis (for inflammation and cartilage degradation biomarkers). The LP reduced the nitric oxide and proteoglycan release from the cartilage explants under IL-1beta induction. The radiological, macroscopic, microscopic and histological images showed the OA rats treated with LP and diclofenac had significantly reduced osteophytes and cartilage erosions compared to non-treated OA rats. The extract significantly up-regulated the anti-inflammatory interleukin-10, collagen type II and down-regulated pro-inflammatory PTGS2 (prostaglandin-endoperoxide synthase 2) mRNA expressions compared to non-treated control. The LP treatment significantly reduced serum collagenases (MMP-1 and MMP-3) and collagen type II degradation biomarker (CTX-II) levels in OA rats. The LP containing myricetin and gallic acid suppressed inflammation, collagenases and cartilage degradation, and helped cartilage matrix synthesis, to prevent OA at the dose equivalent to 30-60 mg/kg daily for humans. PMID- 29460079 TI - The Biological Contributions to Gender Identity and Gender Diversity: Bringing Data to the Table. AB - The American Psychological Association defines gender identity as, "A person's deeply-felt, inherent sense of being a boy, a man, or a male; a girl, a woman, or a female; or an alternative gender (e.g., genderqueer, gender nonconforming, gender neutral) that may or may not correspond to a person's sex assigned at birth or to a person's primary or secondary sex characteristics" (American Psychological Association, Am Psychol 70(9):832-864, 2015). Here we review the evidence that gender identity and related socially defined gender constructs are influenced in part by innate factors including genes. Based on the data reviewed, we hypothesize that gender identity is a multifactorial complex trait with a heritable polygenic component. We argue that increasing the awareness of the biological diversity underlying gender identity development is relevant to all domains of social, medical, and neuroscience research and foundational for reducing health disparities and promoting human-rights protections for gender minorities.

AB - AIMS: To assess the metabolic health of obese and non-obese women at high GDM risk 5 years postpartum. METHODS: This is a secondary analysis of the 5-year follow-up of the RADIEL GDM prevention study including 333 women at high GDM risk (BMI >= 30 kg/m2 and/or previous GDM). Five years postpartum metabolic health was assessed including anthropometric measurements, oral glucose tolerance test, lipid metabolism, and body composition as well as medical history questionnaires. For the analysis, we divided the women into four groups based on parity, BMI, and previous history of GDM. RESULTS: Five years postpartum impaired glucose regulation (IFG, IGT, or diabetes) was diagnosed in 15% of the women; 3.6% had type 2 diabetes. The highest prevalence was observed among obese women with a history of GDM (26%), and the lowest prevalence (8%) among primiparous obese women (p = 0.021). At follow-up 25-39% of the obese women fulfilled the diagnostic criteria for the metabolic syndrome, in the non-obese group 11% (p < 0.001). This was associated with body fat percentage. The non-obese group, however, faced metabolic disturbances (IFG, IGT, diabetes, or metabolic syndrome) at a significantly lower BMI (p < 0.001). Among women who were non-obese before pregnancy, 5 years postpartum, the obesity prevalence based on BMI was 14% and based on body fat percentage 58%. CONCLUSIONS: The prevalence of impaired glucose regulation and metabolic syndrome is high 5 years postpartum among women at high risk of GDM. There are high-risk women also among the non-obese, who develop metabolic derangements already at a lower BMI. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov, www.clinicaltrials.com , NCT01698385.

AB - Many industry leaders and academics from the field of machine ethics would have us believe that the inevitability of robots coming to have a larger role in our lives demands that robots be endowed with moral reasoning capabilities. Robots endowed in this way may be referred to as artificial moral agents (AMA). Reasons often given for developing AMAs are: the prevention of harm, the necessity for public trust, the prevention of immoral use, such machines are better moral reasoners than humans, and building these machines would lead to a better understanding of human morality. Although some scholars have challenged the very initiative to develop AMAs, what is currently missing from the debate is a closer examination of the reasons offered by machine ethicists to justify the development of AMAs. This closer examination is especially needed because of the amount of funding currently being allocated to the development of AMAs (from funders like Elon Musk) coupled with the amount of attention researchers and industry leaders receive in the media for their efforts in this direction. The stakes in this debate are high because moral robots would make demands on society; answers to a host of pending questions about what counts as an AMA and whether they are morally responsible for their behavior or not. This paper shifts the burden of proof back to the machine ethicists demanding that they give good reasons to build AMAs. The paper argues that until this is done, the development of commercially available AMAs should not proceed further. PMID- 29460082 TI - Testing Hypotheses on Risk Factors for Scientific Misconduct via Matched-Control Analysis of Papers Containing Problematic Image Duplications. AB - It is commonly hypothesized that scientists are more likely to engage in data falsification and fabrication when they are subject to pressures to publish, when they are not restrained by forms of social control, when they work in countries lacking policies to tackle scientific misconduct, and when they are male. Evidence to test these hypotheses, however, is inconclusive due to the difficulties of obtaining unbiased data. Here we report a pre-registered test of these four hypotheses, conducted on papers that were identified in a previous study as containing problematic image duplications through a systematic screening of the journal PLoS ONE. Image duplications were classified into three categories based on their complexity, with category 1 being most likely to reflect unintentional error and category 3 being most likely to reflect intentional fabrication. We tested multiple parameters connected to the hypotheses above with a matched-control paradigm, by collecting two controls for each paper containing duplications. Category 1 duplications were mostly not associated with any of the parameters tested, as was predicted based on the assumption that these duplications were mostly not due to misconduct. Categories 2 and 3, however, exhibited numerous statistically significant associations. Results of univariable and multivariable analyses support the hypotheses that academic culture, peer control, cash-based publication incentives and national misconduct policies might affect scientific integrity. No clear support was found for the "pressures to publish" hypothesis. Female authors were found to be equally likely to publish duplicated images compared to males. Country-level parameters generally exhibited stronger effects than individual-level parameters, because developing countries were significantly more likely to produce problematic image duplications. This suggests that promoting good research practices in all countries should be a priority for the international research integrity agenda. PMID- 29460083 TI - Kidney function and use of nonsteroidal anti-inflammatory drugs among elderly people: a cross-sectional study on potential hazards for an at risk population. AB - : Background Renal elimination normally decreases with age. Nonsteroidal antiinflammatory drugs (NSAIDs) carry a risk of additional kidney damage. Objective The aims of this study were to assess the prevalence of NSAIDs in the elderly (aged >= 65) population in Sweden, explore reasons for any possible differences in the level of use and assess their kidney functions. Setting Data were obtained from the cohort study Good Aging in Skane, Sweden. Patients aged 65 or more were included. Methods Medication lists were collected as well as variables such as cognition and education levels. Glomerular filtration rate was estimated from creatinine and cystatin C. Descriptive statistics and multiple linear regression analysis were used. MAIN OUTCOME MEASURE: NSAID use among the general elderly population. Results A total of 1798 patients were included. Approximately six percent (n = 105) of the people in the study group were using NSAIDs and of those 82 (78%) bought NSAIDs over the counter (OTC). 42% of those buying NSAIDs OTC showed an estimated glomerular filtration rate below 60 ml/min/1.73 m2. Education level did not affect the use of nonsteroidal anti inflammatory drugs, nor did age. NSAIDs were more commonly used than other recommended analgesics. Conclusion Many people are unaware of the risks associated with the use of NSAIDs. The findings imply that the frailest elderly use NSAIDs to the same extent as the younger elderly do. It is important that information about safety of these drugs be communicated to both patients and healthcare professionals. PMID- 29460084 TI - Persistent Organic Pollutants Residues in Human Breast Milk from Bathinda and Ludhiana Districts of Punjab, India. AB - In the present study, persistent organic pollutants (POPs), including six congeners of polychlorinated biphenyls (PCBs) and organochlorine pesticides, were estimated in human breast milk samples collected from two districts of Punjab (India). The mean concentrations of POP residues were recorded higher in Bathinda district (PCBs: 33.7; DDTs: 519.2; HCHs: 46.6 ng g-1 lipid wt.) than Ludhiana (PCBs: 24.2; DDTs; 415.3; HCHs; 35.5 ng g-1 lipid wt.). Levels of PCBs and DDTs were observed higher in primiparas, whereas HCHs residues were seen more in multiparas. Risk analysis to POPs exposure through breast milk reflected that the daily intake for some infants was close to or above the tolerable daily intake limit for detrimental effects, which may raise a health concern. Comparative evaluation of present data indicated that DDT and HCHs residue levels in human breast milk from Punjab, India were among the lowest values reported for developing countries. The first-order kinetic reaction at a steady-state condition used to estimate the half-life of DDT and HCH suggested that DDT levels have declined from 18,211 to 490 ng g-1 lipid wt. with a half-life (Tdec1/2) of 3.25 years over a span of 15 years. Similarly, HCH levels have decreased from 8609 to 46.6 ng g-1 in this duration with Tdec1/2 of 2.25 years. Because some infants are still at risk, continuous monitoring of POPs in human milk is needed for surveillance and interpretation of time trends and for linkage to strict enforcement of agricultural regulations. PMID- 29460085 TI - Bioaccumulation Study of Produced Water Discharges from Southeastern Brazilian Offshore Petroleum Industry Using Feral Fishes. AB - The main effluent of oil and gas production is the discharge of produced water (PW). Despite the potential environmental impact, the structure of oil and gas platforms can act as artificial reefs. Two species of fish, Caranx crysos and Tylosurus acus, were captured under two discharging platforms at Campos Basin, P19 and P40. A nondischarging platform, P25, was taken as reference. The highest median concentration of PAH in muscle tissue was observed for C. Crysos at P40 (219.38 ng g-1) followed by P19 (68.26 ng g-1). For T. acus, the highest median concentrations were 40.07 and 42.21 ng g-1 from P19 and P40 respectively. P25 presented the smallest recorded concentrations. The results of PAH in the muscle tissue of C. crysos enabled to distinguish the platforms with PW discharge from the platform without discharge. Trace elements concentrations reflected the background levels and were not influenced by the PW release. PMID- 29460086 TI - Systematic Analysis of Primary Sequence Domain Segments for the Discrimination Between Class C GPCR Subtypes. AB - G-protein-coupled receptors (GPCRs) are a large and diverse super-family of eukaryotic cell membrane proteins that play an important physiological role as transmitters of extracellular signal. In this paper, we investigate Class C, a member of this super-family that has attracted much attention in pharmacology. The limited knowledge about the complete 3D crystal structure of Class C receptors makes necessary the use of their primary amino acid sequences for analytical purposes. Here, we provide a systematic analysis of distinct receptor sequence segments with regard to their ability to differentiate between seven class C GPCR subtypes according to their topological location in the extracellular, transmembrane, or intracellular domains. We build on the results from the previous research that provided preliminary evidence of the potential use of separated domains of complete class C GPCR sequences as the basis for subtype classification. The use of the extracellular N-terminus domain alone was shown to result in a minor decrease in subtype discrimination in comparison with the complete sequence, despite discarding much of the sequence information. In this paper, we describe the use of Support Vector Machine-based classification models to evaluate the subtype-discriminating capacity of the specific topological sequence segments. PMID- 29460087 TI - Prescription Changes During Geriatric Care Episodes: A Trend Analysis Conducted in Sweden. AB - BACKGROUND: The number of drugs prescribed for old people has been rising in recent decades. With increasing age and multiple medications, the risk of complications and drug prescription complexity increases. Multiple changes to prescriptions could be a factor that improves treatment quality. OBJECTIVES: Our objective was to investigate trends in drug prescriptions and factors that contribute to prescription changes. Specific objectives were to find out whether high numbers of prescription changes are significantly correlated with age, sex, comorbidity, length of care episode, and number of drugs. METHODS: Data were extracted from geriatric clinic records in Stockholm in 2005, 2010, and 2015. Indicators for good drug therapy were used to assess the effects of prescription changes on quality, using an index of inappropriate drug use (IDU). Data were analyzed with Student's t-test, PR test, Wilcoxon's rank sum test, and linear regression. RESULTS: Patients had more comorbidities and used more drugs but had shorter hospital stays and significantly fewer prescription changes in 2015 than in 2005. Length of care episode was significantly associated with prevalence of prescription changes. Our model showed that, for each day by which the length of care episode decreased, the number of prescription changes decreased by 8%. The number of prescription changes was negatively correlated to the IDU index score. CONCLUSIONS: The study showed that more prescription changes were associated with longer care episodes and improved drug prescribing quality as per the IDU index. Given prescription changes are regarded as a quality factor in geriatric care, quality may have decreased along with the length of care episodes between 2005 and 2015. PMID- 29460088 TI - Vascular deficiency of Smad4 causes arteriovenous malformations: a mouse model of Hereditary Hemorrhagic Telangiectasia. AB - Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant vascular disorder that leads to abnormal connections between arteries and veins termed arteriovenous malformations (AVM). Mutations in TGFbeta pathway members ALK1, ENG and SMAD4 lead to HHT. However, a Smad4 mouse model of HHT does not currently exist. We aimed to create and characterize a Smad4 endothelial cell (EC) specific, inducible knockout mouse (Smad4f/f;Cdh5-CreERT2) that could be used to study AVM development in HHT. We found that postnatal ablation of Smad4 caused various vascular defects, including the formation of distinct AVMs in the neonate retina. Our analyses demonstrated that increased EC proliferation and size, altered mural cell coverage and distorted artery-vein gene expression are associated with Smad4 deficiency in the vasculature. Furthermore, we show that depletion of Smad4 leads to decreased Vegfr2 expression, and concurrent loss of endothelial Smad4 and Vegfr2 in vivo leads to AVM enlargement. Our work provides a new model in which to study HHT-associated phenotypes and links the TGFbeta and VEGF signaling pathways in AVM pathogenesis. PMID- 29460089 TI - Competing nomograms help in the selection of elderly patients with colon cancer for adjuvant chemotherapy. AB - PURPOSE: The extent to which >= 70 year patients with colon cancer benefit from adjuvant chemotherapy in the presence of competing risks remains controversial. METHODS: 18,937 patients >= 70 years with high-risk stage II and stage III colon cancer were retrospectively reviewed from SEER database. Propensity score matching (PSM) was used to adjust for potential baseline confounding. The nomograms were developed based on the competing model to describe the individual probability of colon cancer-specific death (CCSD) and non-CCSD. The subpopulation treatment-effect pattern plot (STEPP) was used to estimate the treatment-effect heterogeneity. RESULTS: In the high-risk stage II subgroup, compared to the non recipients, the hazard ratios (HR) of overall mortality for recipients were 0.83 (P = 0.001). The subdistribution hazard ratio (SHR) of CCSD for receipts was 1.22 (P = 0.021). The SHR of non-CCSD was 0.63 (P < 0.001). In the stage III subgroup, compared to non-recipients, the HR of the overall mortality for the recipients was 0.62 (P < 0.001). The SHR of CCSD was 0.77 (P < 0.001). The SHR of non-CCSD was 0.58 (P < 0.001). The chemotherapy efficacy differed significantly by risk score of non-CCSD (non-CCSD-RS) (P < 0.001). Recipients with high non-CCSD-RS had a rate of CCSD comparative to that of non-recipients (SHR 0.90, P = 0.150) in the stage III subgroup. CONCLUSIONS: A survival analysis based on the overall mortality did not correctly interpret the effect of chemotherapy. Adjuvant chemotherapy did not provide an additional benefit to patients with high-risk stage II or patients with stage III at high risk of non-cancer death. PMID- 29460090 TI - Medical Big Data Warehouse: Architecture and System Design, a Case Study: Improving Healthcare Resources Distribution. AB - The huge increases in medical devices and clinical applications which generate enormous data have raised a big issue in managing, processing, and mining this massive amount of data. Indeed, traditional data warehousing frameworks can not be effective when managing the volume, variety, and velocity of current medical applications. As a result, several data warehouses face many issues over medical data and many challenges need to be addressed. New solutions have emerged and Hadoop is one of the best examples, it can be used to process these streams of medical data. However, without an efficient system design and architecture, these performances will not be significant and valuable for medical managers. In this paper, we provide a short review of the literature about research issues of traditional data warehouses and we present some important Hadoop-based data warehouses. In addition, a Hadoop-based architecture and a conceptual data model for designing medical Big Data warehouse are given. In our case study, we provide implementation detail of big data warehouse based on the proposed architecture and data model in the Apache Hadoop platform to ensure an optimal allocation of health resources. PMID- 29460091 TI - Factors in Removing Job Restrictions for Cancer Survivors in the United Kingdom Royal Air Force. AB - Purpose To identify personal, occupational and clinical factors associated with the lifting of restrictions on duties among Royal Air Force (RAF) personnel who have returned to work after surviving primary cancer treatment. Methods A retrospective cohort of 205 RAF personnel aged 18-58 with cancer diagnosed between 2001 and 2011 was followed-up until May 2012. Personal, occupational, and clinical information was extracted from occupational health and primary care records. Predictors of the lifting of (a) employment restrictions on UK duties at 18 months after diagnosis and (b) the lifting of all deployment restrictions at the end of the study were analysed using logistic and Cox regression models. Results At 18 months, 62% of the cancer survivors had restrictions on their UK duties lifted. The positive independent predictors of unrestricted UK duties are testicular cancer (OR 5.34; 95% CI 1.21-23.6) and no treatment being required (16.8; 1.11-255.2). The lifting of all employment restrictions and return to full deployability was achieved by 41% of the participants (median time 2.1 years), with testicular cancer (HR 2.69; 95% CI 1.38-5.26) and age at diagnosis (1.05; 1.01-1.09) being the positive independent predictors of faster lifting of all restrictions. Conclusion Diagnostic group, prognosis and type of treatment are not the only predictor of employment outcome after cancer. Patient-centred factors such as smoking, age, fatigue, job status, job type and length of employment are also important predictors of return to pre-morbid job function in cancer survivors in the RAF. PMID- 29460093 TI - Vitamin D testing: finding a balance. PMID- 29460092 TI - Balancing in- and out-breeding by the predatory mite Phytoseiulus persimilis. AB - In- and out-breeding depressions are commonly observed phenomena in sexually reproducing organisms with a patchy distribution pattern, and spatial segmentation and/or isolation of groups. At the genetic level, inbreeding depression is due to increased homozygosity, whereas outbreeding depression is due to inferior genetic compatibility of mates. Optimal outbreeding theory suggests that intermediate levels of mate relatedness should provide for the highest fitness gains. Here, we assessed the fitness consequences of genetic relatedness between mates in plant-inhabiting predatory mites Phytoseiulus persimilis, which are obligatory sexually reproducing but haplo-diploid. Both females and males arise from fertilized eggs but males lose the paternal chromosome set during embryogenesis, dubbed pseudo-arrhenotoky. Phytoseiulus persimilis are highly efficacious in reducing crop-damaging spider mite populations and widely used in biological control. Using iso-female lines of two populations, from Sicily and Greece, we assessed the fecundity of females, and sex ratio of their offspring, that mated with either a sibling, a male from the same population or a male from the other population. Additionally, we recorded mating latency and duration. Females mating with a male from the same population produced more eggs, with a lower female bias, over a longer time than females mating with a sibling or with a male from the other population. Mating latency was unaffected by mate relatedness; mating duration was disproportionally long in sibling couples, likely indicating female reluctance to mate and sub-optimal spermatophore transfer. Our study provides a rare example of in- and out-breeding depression in a haplo-diploid arthropod, supporting the optimal outbreeding theory. PMID- 29460094 TI - Ear, nose and throat involvement in granulomatosis with polyangiitis: how it presents and how it determines disease severity and long-term outcomes. AB - Ear, nose and throat (ENT) manifestations in granulomatosis with polyangiitis (GPA) represent the most frequent symptoms at disease onset. The aim of the study was to analyse ENT involvement at diagnosis, as well as how it could influence relapse rate, mortality and disease severity. A retrospective non-controlled cohort study was performed including all consecutive diagnosed GPA from 1996 to 2016 in two rheumatology centres of Northern Italy, focusing particularly on ENT presenting signs and symptoms at baseline. Eighty-nine patients (48.3% females) with new onset GPA were evaluated. They were mostly Caucasian (97.7%), middle aged (mean 54.5 years) and more frequently anti-neutrophil cytoplasmic antibodies (ANCA) positive (78.6%) with PR3 specificity (81.4%). At diagnosis, ENT involvement was reported in 71.9% patients, second only to systemic symptoms. These patients were significantly younger at disease onset (0.013), with less frequent renal involvement (0.014) irrespectively to ANCA status, but with significantly higher Vasculitis Damage Index (VDI) (0.001). The most frequent ENT manifestation was sinonasal involvement (58.4%, 73% of which with nasal inflammation/chronic sinusitis and 48% with nasal crusting), while otologic involvement (mainly otitis media/otomastoiditis) was observed in 34.8%. ENT-GPA patients presented a higher survival rate at 5 years (98.1 vs 77.7%, 0.049), and ENT involvement resulted to be an independent predictor of better outcome (OR 0.37, 95% CI 0.2-0.8, 0.019). Our data confirms that ENT involvement is not only one of the key clinical features of GPA, but also could point out a milder GPA subset with lower renal involvement and lower mortality rate, irrespectively to ANCA status. PMID- 29460095 TI - Diagnosis, characteristics, and treatment of breast carcinomas within benign fibroepithelial tumors. AB - BACKGROUND: Breast carcinoma arising in a benign fibroepithelial tumor is rare, and is usually discovered incidentally during examination of the breast mass. METHODS: We evaluated the clinicopathological features, treatment, and prognosis of seven women with breast carcinomas within benign fibroepithelial tumors, diagnosed and treated at a single institution between 2011 and 2015. RESULTS: Seven women, aged 21-64 years, visited our hospital complaining of a breast mass detected by self-checking or screening examination. All patients had well demarcated movable breast masses. Ultrasonography showed circumscribed masses suggesting benign tumors in all cases, and mammography revealed well-defined, high-density masses, with or without calcification. The masses progressed in two patients. A preoperative histological diagnosis of carcinoma was made following needle biopsy in four patients. Tumorectomy, breast-conserving surgery, and mastectomy were performed in three, two, and two patients, respectively. One patient underwent lymph node dissection and another underwent sentinel node biopsy. Histologically, the masses were diagnosed as invasive ductal carcinoma, ductal carcinoma in situ or lobular carcinoma in situ, arising in a benign phyllodes tumor, fibroadenoma, or fibroadenomatoid mastopathy. Lymph node metastasis was detected in two patients. There was no recurrence in any of the patients. CONCLUSIONS: Although a carcinoma within a preexisting benign fibroepithelial tumor is extremely rare, it is important to be aware of the possibility of invasive and metastatic disease. PMID- 29460096 TI - Body mass index and age at natural menopause: an international pooled analysis of 11 prospective studies. AB - Current evidence on the association between body mass index (BMI) and age at menopause remains unclear. We investigated the relationship between BMI and age at menopause using data from 11 prospective studies. A total of 24,196 women who experienced menopause after recruitment was included. Baseline BMI was categorised according to the WHO criteria. Age at menopause, confirmed by natural cessation of menses for >= 12 months, was categorised as < 45 years (early menopause), 45-49, 50-51 (reference category), 52-53, 54-55, and >= 56 years (late age at menopause). We used multinomial logistic regression models to estimate multivariable relative risk ratios (RRRs) and 95% confidence intervals (CI) for the associations between BMI and age at menopause. The mean (standard deviation) age at menopause was 51.4 (3.3) years, with 2.5% of the women having early and 8.1% late menopause. Compared with those with normal BMI (18.5-24.9 kg/m2), underweight women were at a higher risk of early menopause (RRR 2.15, 95% CI 1.50-3.06), while overweight (1.52, 1.31-1.77) and obese women (1.54, 1.18 2.01) were at increased risk of late menopause. Overweight and obesity were also significantly associated with around 20% increased risk of menopause at ages 52 53 and 54-55 years. We observed no association between underweight and late menopause. The risk of early menopause was higher among obese women albeit not significant (1.23, 0.89-1.71). Underweight women had over twice the risk of experiencing early menopause, while overweight and obese women had over 50% higher risk of experiencing late menopause. PMID- 29460097 TI - Prognostic role of high sensitivity C-reactive protein and interleukin-6 in glioma and meningioma patients. AB - High sensitivity C-reactive protein (hsCRP) and interleukin-6 (IL-6) can be important prognostic indicators of brain tumor patients. We investigated the association of circulating IL-6 and hsCRP concentrations with discharge outcomes and survival of glioma and meningioma patients. One-hundred and sixty-three (115 women; median age 57 years) patients admitted for meningioma (n = 94), high-grade glioma (n = 48) and low-grade glioma (n = 21) surgery were enrolled in this prospective cohort study. Serum samples were collected within 24 h of admission. Discharge outcome was evaluated using the Glasgow Outcome Scale (unfavorable outcome = score from 1 to 3). Follow-up continued until November, 2016. Elevated IL-6 (>= 2 pg/ml) and hsCRP (>= 1 mg/l) concentrations were present in 25 and 35% of brain tumor patients, respectively. Elevated IL-6 concentrations were associated with unfavorable outcome at hospital discharge, adjusting for brain tumor histological diagnosis, patient age and gender (OR 2.39, 95% CI 0.97-5.91, p = 0.05). Elevated hsCRP concentrations were not associated with discharge outcome (p = 0.13). In multivariate Cox regression analyses adjusted for patient age, gender, extent of tumor resection and adjuvant treatment, elevated IL-6 concentration was associated with greater mortality risk in high-grade glioma patients (OR 2.623; 95% CI 1.129-5.597; p = 0.01), while elevated hsCRP concentration was associated with greater mortality risk in meningioma patients (OR 3.650; 95% CI 1.038-12.831; p = 0.04). Elevated IL-6 concentration is associated with greater unfavorable outcome risk in brain tumor patients and with greater mortality in high-grade glioma patients, while elevated hsCRP concentration is associated with greater mortality in meningioma patients. PMID- 29460099 TI - R0: Host Longevity Matters. AB - The basic reproduction ratio, R0, is a fundamental concept in epidemiology. It is defined as the total number of secondary infections brought on by a single primary infection, in a totally susceptible population. The value of R0 indicates whether a starting epidemic reaches a considerable part of the population and causes a lot of damage, or whether it remains restricted to a relatively small number of individuals. To calculate R0 one has to evaluate an integral that ranges over the duration of the infection of the host. This duration is, of course, limited by remaining host longevity. So, R0 depends on remaining host longevity and in this paper we show that for long-lived hosts this aspect may not be ignored for long-lasting infections. We investigate in particular how this epidemiological measure of pathogen fitness depends on host longevity. For our analyses we adopt and combine a generic within- and between-host model from the literature. To find the optimal strategy for a pathogen from an evolutionary point of view, we focus on the indicator [Formula: see text], i.e., the optimum of R0 as a function of its replication and mutation rates. These are the within host parameters that the pathogen has at its disposal to optimize its strategy. We show that [Formula: see text] is highly influenced by remaining host longevity in combination with the contact rate between hosts in a susceptible population. In addition, these two parameters determine whether a killer-like or a milker like strategy is optimal for a given pathogen. In the killer-like strategy the pathogen has a high rate of reproduction within the host in a short time span causing a relatively short disease, whereas in the milker-like strategy the pathogen multiplies relatively slowly, producing a continuous small amount of offspring over time with a small effect on host health. The present research allows for the determination of a bifurcation line in the plane of host longevity versus contact rate that forms the boundary between the milker-like and killer like regions. This plot shows that for short remaining host longevities the killer-like strategy is optimal, whereas for very long remaining host longevities the milker-like strategy is advantageous. For in-between values of host longevity, the contact rate determines which of both strategies is optimal.

PMID- 29460101 TI - Pulse-echo ultrasound method for detection of post-menopausal women with osteoporotic BMD. AB - : We lack effective diagnostics of osteoporosis at the primary health care level. An ultrasound device was used to identify subjects in the osteoporotic range as defined by DXA. A case finding strategy combining ultrasound results with DXA measurements for patients with intermediate ultrasound results is presented. INTRODUCTION: We lack effective screening and diagnostics of osteoporosis at primary health care. In this study, a pulse-echo ultrasound (US) method is investigated for osteoporosis screening. METHODS: A total of 1091 Caucasian women (aged 50-80 years) were recruited for the study and measured with US in the tibia and radius. This method measures cortical thickness and provides an estimate of bone mineral density (BMD) and density index (DI). BMD assessment of the hip was available for 988 women. A total of 888 women had one or more risk factors for osteoporosis (OP susp ), and 100 women were classified healthy. Previously determined thresholds for the DI were evaluated for assessment of efficacy of the technique to detect hip BMD at osteoporotic range (T-score at or below - 2.5). RESULTS: In the OP susp group, the application of thresholds for the DI showed that approximately 32% of the subjects would require an additional DXA measurement. The multi-site ultrasound (US) measurement-based DI showed 93.7% sensitivity and 81.6% specificity, whereas the corresponding values for single site US measurement-based DI were 84.7 and 82.0%, respectively. The ultrasound measurements showed a high negative predictive value 97.7 to 99.2% in every age decade examined (ages 50-59, 60-69, 70-79 years). CONCLUSIONS: The study data demonstrate that a strategy of combining ultrasound measurement with added DXA measurements in cases with intermediate ultrasound results (about 30%) can be useful for identifying subjects at risk for a low bone mineral density in the osteoporotic range. PMID- 29460102 TI - Economic impact and cost-effectiveness of fracture liaison services: a systematic review of the literature. AB - Fracture liaison services (FLS), implemented in different ways and countries, are reported to be a cost-effective or even a cost-saving secondary fracture prevention strategy. This presumed favorable cost-benefit relationship is encouraging and lends support to expanded implementation of FLS per International Osteoporosis Foundation Best Practice Standards. This study summarizes the economic impact and cost-effectiveness of FLS implemented to reduce subsequent fractures in individuals with osteoporosis. This systematic review identified studies reporting economic outcomes for FLS in osteoporotic patients aged 50 and older through a comprehensive search of MEDLINE, EMBASE, Cochrane Central, and PubMed of studies published January, 2000 to December, 2016. Grey literature (e.g., Google scholar, conference abstracts/posters) were also hand searched through February 2017. Two independent reviewers screened titles and abstracts and conducted full-text review on qualified articles. All disagreements were resolved by discussion between reviewers to reach consensus or by a third reviewer. In total, 23 qualified studies that evaluated the economic aspects of FLS were included: 16 cost-effectiveness studies, 2 cost-benefit analyses, and 5 studies of cost savings. Patient populations varied (prior fragility fracture, non-vertebral fracture, hip fracture, wrist fracture), and FLS strategies ranged from mail-based interventions to comprehensive nurse/physician-coordinated programs. Cost-effectiveness studies were conducted in Canada, Australia, USA, UK, Japan, Taiwan, and Sweden. FLS was cost-effective in comparisons with usual care or no treatment, regardless of the program intensity or the country in which the FLS was implemented (cost/QALY from $3023-$28,800 US dollars (USD) in Japan to $14,513-$112,877 USD in USA. Several studies documented cost savings. FLS, implemented in different ways and countries, are reported to be cost-effective or even cost-saving. This presumed favorable cost-benefit relationship is encouraging and lends support to expanded implementation of FLS per International Osteoporosis Foundation Best Practice Standards. PMID- 29460103 TI - Parkinson's disease and the risk of osteoporotic vertebral compression fracture: a nationwide population-based study. AB - : Patients with Parkinson's disease (PD) were at higher risk of osteoporotic vertebral compression fractures (OVCF) compared to controls and had elevated mortality rates. Compared to conservative treatment, surgical treatment for OVCF in PD patients seemed to be associated with better outcomes. INTRODUCTION: The purpose of this study was to evaluate the risk of OVCF in patients with PD. METHODS: Data from patients over the age of 60 years who were diagnosed with PD were collected between 2004 and 2013 from the Korean National Health Insurance Database (n = 3370). The comparison group (non-PD) consisted of randomly selected patients (five per patient with PD; n = 16,850) matched to the PD group, who were newly diagnosed annually according to age and sex. Cox proportional hazard regressions were used to examine the relationships between osteoporosis, OVCF, surgery for OVCF, and PD. Household income and residential area of patients were also assessed. Overall survival rates were calculated after adjusting for confounding factors, such as hypertension, diabetes mellitus, and chronic kidney disease. RESULTS: OVCF was developed in 12.5% of patients in the PD group and in 7.4% of patients in the control group. PD was associated with increased risk of osteoporosis (hazard ratio [HR], 1.32; 95% confidence interval [CI], 1.21-1.43; p < 0.001), OVCF (HR 1.66; 95% CI, 1.47-1.87; p < 0.001), and surgery for OVCF (HR 2.69; 95% CI, 1.78-4.08; p < 0.001). Household income was not significantly related with development of osteoporosis, incidence of OVCF, or surgery for OVCF. Residential area was statistically associated with osteoporosis, OVCF, and surgery for OVCF. The mortality rate of the PD group was about 1.7 times higher than that of the non-PD group after adjusting for potential confounders, and the mortality rate of the PD with OVCF group was higher than that of the non-PD group, but not significantly (p = 0.09). The survival rate of the PD group with surgery for OVCF showed a trend toward a more positive prognosis compared with that of the PD group with conservative treatment. CONCLUSIONS: Patients with PD had significantly increased risk of osteoporosis and OVCF. Surgical treatment for OVCF in PD patients was associated with a better prognosis than conservative treatment.

PMID- 29460105 TI - The importance of standardisation of measurement and reference intervals for detection of phaeochromocytoma and paraganglioma (PPGL). AB - A 51-year-old male presented 25 years ago with excessive sweating and haematuria. Blood pressure was labile. CT abdomen showed a large right-sided adrenal mass. Two 24-h urine collections showed elevated urinary catecholamines. Right adrenal resection was performed; a phaeochromocytoma (PC) was confirmed histologically. Two decades later, the patient represented with excessive sweating and measured variable blood pressure readings. Measurement of plasma metanephrines (PMets) showed elevated normetanephrine (NMN) [50,250 (R.I. 0-1180) pmol/L] and metanephrine (MN) [1030 (R.I. 0-510) pmol/L] values. CT abdomen showed a 100 * 90 * 63 mm enhancing mass in the right retroperitoneum. Curative resection was undertaken confirming recurrent PC. Follow-up post-resection, plasma NMN was discordant, 1314 pmol/L (above decision threshold) at 30 min and 911 pmol/L (below decision threshold) at 40 min. Acute clinical awareness of persistent disease mandated the performance of a metaiodobenzylguanidine (MIBG) scan and CT abdomen. These confirmed residual disease in the upper right side of the retroperitoneum. Persistent disease following redo surgery could have been missed if only seated-sampling upper reference limits were applied to PMets collected at 40 min. Our experience with this patient triggered a review of our PMets sampling strategy. There was no statistically significant difference in PMets sampled at 30 and at 40 min seated-rest. Optimum diagnostic test accuracy was achieved using a supine-sampling strategy at a single time point (30 min). Our case highlights the importance of maintaining a high index of clinical suspicion for residual/recurrent disease in the face of inconclusive biochemistry, followed by appropriate targeted radiology using MIBG or PET-CT in patients with PPGL. PMID- 29460106 TI - Assessment of Chronic Illness-Related Cognitive Fusion: Preliminary Development and Validation of a New Scale with an IBD Sample. AB - Although research recognizes the advantages of creating specific content measures, no specific measure of chronic illness-related cognitive fusion had been developed to date. The current study presents the development and validation of the Cognitive Fusion Questionnaire-Chronic Illness (CFQ-CI) in a sample of inflammatory bowel disease (IBD) patients and the analysis of the role of this construct in the psychological health of those patients. Results indicated that the 7-item CFQ-CI was a unidimensional measure of cognitive fusion in patients with chronic illnesses, and that scores had adequate/good internal consistency and construct, convergent, and discriminant validity. This study also showed that chronic illness-related cognitive fusion as assessed by the CFQ-CI acted as a mediator in the association between both IBD-related symptoms and shame with quality of life. The development of the CFQ-CI may thus contribute to a better understanding of the mechanisms influencing functional outcomes in chronic illness. PMID- 29460107 TI - Assessing Psychiatric Symptoms in Youth Affected by HIV: Comparing a Brief Self Administered Rating Scale with a Structured Diagnostic Interview. AB - Brief psychiatric assessment tools are needed for evaluating children affected by HIV for emotional and behavioral problems. We compared a self-administered symptom rating scale (CASI-4R) to a semi-structured diagnostic interview (DICA-P) in 136 U.S. children affected by HIV. Agreement and performance measures for the two instruments were computed for attention deficit hyperactivity disorder, depression, anxiety, and disruptive behavior. Correlations and regression analyses were conducted to compare the two instruments, and to evaluate their associations with social, academic, and global function. Higher CASI-4R symptom severity scores were associated with DICA diagnoses (p < 0.02 for all disorders). Agreement (kappa) between DICA diagnoses and CASI-4R Clinical Cutoffs (which incorporated symptoms and impairment) was low to moderate (0.19-0.40 for all disorders). Thirty-two percent of cases with a DICA diagnosis were identified by the CASI-4R Clinical Cutoff (sensitivity), yet over 90% of DICA-negative cases were negative by the CASI-4R (specificity). Sensitivity was higher using CASI-4R Severity Score thresholds based on median scores compared to the DICA diagnoses. The presence and severity of psychiatric symptoms and impairment were associated with poorer academic, social, and global function. The CASI-4R symptom checklist can be used to inexpensively screen youth affected by HIV for emotional and behavioral problems, although it is important that there be appropriate mental health evaluation follow-up. PMID- 29460108 TI - Stressors increase leptin receptor-expressing thymic epithelial cells in the infant/child thymus. AB - The thymus, the organ that is the most sensitive to stress, presents acute involution as a result of exposure to strong stress in childhood. Thymic involution is thus often considered evidence of child abuse/neglect in forensic autopsies. A portion of the thymic epithelial cells express leptin receptor, and leptin showed a thymo-protective function against stress-induced thymic involution in an animal model. Leptin receptor-expressing thymic epithelial cells (LR-TECs) may play a key role in the thymic remodeling provoked by a stressful environment. Here, we sought to clarify the changes of histopathological findings and human LR-TECs in stressful environment. We examined human thymus specimens obtained from 40 forensic autopsy cases (26 male, 14 female; age 21 to 3221 days). We divided the cases into stressor-positive (SP, n = 29) and stressor negative (SN, n = 11) groups. Cases were classified according to the histological classification of thymic involution and investigated by leptin receptor immunostaining. The results revealed that (1) the SP group showed obvious histological thymic involution (p < 0.01) and (2) the LR-TECs/TECs ratio in the cortex was markedly and significantly increased in the SP group compared to the SN group (p < 0.01). The increase in the cortical LR-TECs/TECs ratio in the SP group may be part of the stress response mechanism in the human thymus. We thus speculate that the quantification of LR-TECs in the thymic cortex is a valuable stress marker for forensic autopsy cases. PMID- 29460109 TI - Online selling of wildlife part with spurious name: a serious challenge for wildlife crime enforcement. AB - We examined an online sold product "Hatha Jodi" synonym of "paired arm" for the confirmation of its biological source. It was declared as a plant root. The morphological features of these samples were matched with the "intromittent organs" or "hemi penis" of the monitor lizard. For further confirmation, we used sequencing of a partial fragment of mitochondrial DNA cytochrome b gene. Sequence comparison indicated that these claimed plant products were actually biological samples of a common monitor lizard, Varanus bengalensis. Hence, it exhibited the ongoing illegal trade of the intromittent organ of a prohibited species with a misleading name using low risk and widely adopted modern trading method that imposes a severe challenge for combating against the wildlife crime. PMID- 29460112 TI - Association between oral contraceptives and risk of hemorrhagic stroke: a meta analysis of observational studies. AB - OBJECTIVES: To estimate the risk of hemorrhagic stroke associated with current use of oral contraceptives (OCs), and to further depict how the risk was affected by study characteristics. METHODS: We searched PubMed, Embase, and Cochrane Library for relevant articles published up to February 2017 that examined the association between OC use and risk of hemorrhagic stroke. Two investigators independently reviewed articles based on inclusion criteria. The Newcastle-Ottawa scale was employed to evaluate quality of studies. Random-effects meta-analysis model was used to generate summary risk estimates. RESULTS: Fifteen independent studies (5 cohort studies and 10 case-control studies) with 4271 hemorrhagic stroke cases were included in this meta-analysis. The overall summary odds ratio (OR) for hemorrhagic stroke (HS) in relation to current OC use was 1.39 [95% confidence interval (CI), 1.05-1.83]. Subgroup analyses on hemorrhagic stroke types showed that OC use was associated with subarachnoid hemorrhage (SAH) (OR 1.68; 95% CI 1.21-2.12), but not with intracerebral hemorrhage (ICH) (OR 0.92; 95% CI 0.33-2.54). The risk of hemorrhagic stroke was increased slightly among current OC users with high-dose estrogen (OR 1.60; 95% CI 1.12-2.27). The risk of hemorrhagic stroke was further increased in OC users with additional risk factors including current smoking, hypertension, and history of migraine. CONCLUSIONS: This meta-analysis of observational studies suggests that current use of OCs could contribute to a small increased risk of hemorrhagic stroke, and the increased risk is related to subarachnoid hemorrhage, but not intracerebral hemorrhage. PMID- 29460111 TI - The Changing Age of Individuals Seeking Presymptomatic Genetic Testing for Huntington Disease. AB - Huntington disease (HD) is a progressive neurodegenerative disorder. Presymptomatic genetic testing allows at-risk individuals to clarify their risk status. Understanding the characteristics and motivations of individuals seeking HD presymptomatic genetic testing better equips genetic counselors and other healthcare professionals to provide comprehensive and personalized care. The aims of this study were to (1) determine whether the average age when individuals seek presymptomatic HD genetic testing has decreased over time, (2) assess motivations for seeking testing, (3) explore whether there is a relationship between age and motivations, and (4) explore genetic counselors' perceptions of the shift in age. Data from the US HD testing centers (N = 4) were analyzed. A small but statistically significant decrease in age of individuals seeking presymptomatic testing was observed (p = 0.045). HD community members (N = 77) were surveyed regarding presymptomatic testing motivations. Younger individuals were more likely than older individuals to cite "To learn whether or not you would develop HD" and "To make choices about further education or a career" compared to older individuals (p < 0.05). Conversely, older individuals more frequently cited "To give children a better idea of their risk" (p < 0.002). Sixteen percent of genetic counselors surveyed (6/37) perceived a change in age of testing. All of these respondents had provided HD testing for ten or more years and anecdotally believed the age at testing has decreased over time. Study results help providers personalize counseling based on patient's age and serve as a starting point for more research into the relationship between age at testing and motivations for testing. PMID- 29460110 TI - Operationalizing the Reciprocal Engagement Model of Genetic Counseling Practice: a Framework for the Scalable Delivery of Genomic Counseling and Testing. AB - With the advent of widespread genomic testing for diagnostic indications and disease risk assessment, there is increased need to optimize genetic counseling services to support the scalable delivery of precision medicine. Here, we describe how we operationalized the reciprocal engagement model of genetic counseling practice to develop a framework of counseling components and strategies for the delivery of genomic results. This framework was constructed based upon qualitative research with patients receiving genomic counseling following online receipt of potentially actionable complex disease and pharmacogenomics reports. Consultation with a transdisciplinary group of investigators, including practicing genetic counselors, was sought to ensure broad scope and applicability of these strategies for use with any large-scale genomic testing effort. We preserve the provision of pre-test education and informed consent as established in Mendelian/single-gene disease genetic counseling practice. Following receipt of genomic results, patients are afforded the opportunity to tailor the counseling agenda by selecting the specific test results they wish to discuss, specifying questions for discussion, and indicating their preference for counseling modality. The genetic counselor uses these patient preferences to set the genomic counseling session and to personalize result communication and risk reduction recommendations. Tailored visual aids and result summary reports divide areas of risk (genetic variant, family history, lifestyle) for each disease to facilitate discussion of multiple disease risks. Post-counseling, session summary reports are actively routed to both the patient and their physician team to encourage review and follow-up. Given the breadth of genomic information potentially resulting from genomic testing, this framework is put forth as a starting point to meet the need for scalable genetic counseling services in the delivery of precision medicine. PMID- 29460113 TI - Transcriptome-Wide Identification of Differentially Expressed Genes and Long Non coding RNAs in Aluminum-Treated Rat Hippocampus. AB - Aluminum (Al) is an environmental neurotoxicant with a wide exposure, but the molecular mechanism underlying its toxicity remains unclear. We used RNA sequencing (RNA-seq) in the hippocampus of Al-treated rats to identify 96 upregulated and 652 downregulated mRNAs, and 37 dysregulated long non-coding (lnc)RNAs. Gene ontology analysis showed that dysregulated genes were involved in glial cell differentiation, neural transmission, and vesicle trafficking. Kyoto Encyclopedia of Genes and Genomes pathway analysis revealed clustering of differentially expressed mRNAs and lncRNA target genes in several pathways, including the "adenosine monophosphate-activated protein kinase signaling pathway," "extracellular matrix receptor interaction," "the phosphatidylinositol 3 kinase-protein kinase B signaling pathway," and "focal adhesion" signaling pathway. RNA-seq results were validated by reverse transcription (RT)-PCR. Additionally, Al induced changes to the number and morphology of glial cells in the hippocampus of rats, as shown by glial fibrillary acidic protein (GFAP) and ionized calcium binding adaptor molecule 1 (Iba1) immunochemistry. RT-PCR and western blotting validated the significant increase in expression of glial cell related genes GFAP and SOX10 following Al exposure compared with control rats, consistent with RNA-seq results. Collectively, these results suggest that aberrant mRNAs and lncRNAs respond to Al neurotoxicity, and that glial cell related genes play important roles in the Al neurotoxicity mechanism. These findings provide the basis for designing targeted approaches for the treatment or prevention of Al-induced neurotoxicity. PMID- 29460114 TI - Peripheral Administration of Tetanus Toxin Hc Fragment Prevents MPP+ Toxicity In Vivo. AB - Several studies have shown that intrastriatal application of 1-methyl-4 phenylpyridinium (MPP+) produces similar biochemical changes in rat to those seen in Parkinson's disease (PD), such as dopaminergic terminal degeneration and consequent appearance of motor deficits, making the MPP+ lesion a widely used model of parkinsonism in rodents. Previous results from our group have shown a neuroprotective effect of the carboxyl-terminal domain of the heavy chain of tetanus toxin (Hc-TeTx) under different types of stress. In the present study, pretreatment with the intraperitoneal injection of Hc-TeTx in rats prevents the decrease of tyrosine hydroxylase immunoreactivity in the striatum due to injury with MPP+, when applied stereotaxically in the striatum. Similarly, striatal catecholamine contents are restored, as well as the levels of two other dopaminergic markers, the dopamine transporter (DAT) and the vesicular monoamine transporter-2 (VMAT-2). Additionally, uptake studies of [3H]-dopamine and [3H] MPP+ reveal that DAT action is not affected by Hc-TeTx, discarding a protective effect due to a reduced entry of MPP+ into nerve terminals. Behavioral assessments show that Hc-TeTx pretreatment improves the motor skills (amphetamine induced rotation, forelimb use, and adjusting steps) of MPP+-treated rats. Our results lead us to consider Hc-TeTx as a potential therapeutic tool in pathologies caused by impairment of dopaminergic innervation in the striatum, as is the case of PD.

AB - Solid-state nanopore has captured the attention of many researchers due to its characteristic of nanoscale. Now, different fabrication methods have been reported, which can be summarized into two broad categories: "top-down" etching technology and "bottom-up" shrinkage technology. Ion track etching method, mask etching method chemical solution etching method, and high-energy particle etching and shrinkage method are exhibited in this report. Besides, we also discussed applications of solid-state nanopore fabrication technology in DNA sequencing, protein detection, and energy conversion.

AB - We explored the possibility of the cryo-storage of cord blood hematopoietic stem cells (CBHPSC) with respect to the quantity, quality and biologic efficacy of high altitude (HA) region Abha against sea level (SL) region. The results of the post-processed total nucleated cell count was 8.03 +/- 0.31 * 107 and 8.44 +/- 0.23 * 107 cells in the HA and SL regions respectively. The mean post processing viability of the nucleated cells was about 87.03 +/- 1.39 (HA) and 88.33 +/- 1.55% (SL) while post thaw cells were 85.61 +/- 1.44 (HA) and 86.58 +/- 1.61% (SL) after transient cryo-storage. The proliferation of CBHSCs after thawing were comparable between the HA and SL regions. The results of the colony forming unit (CFU) assays of CFU-E, CFU-GEMM, CFU-GM and BFU-E were comparable between HA and SL in both fresh and post thaw, while a declining trend with viability was significant. The differentiation capability of post thaw samples into adipocytes and osteocytes were comparable between HA and SL regions. Overall from the results, it can be evidenced that HA cord blood collection, processing or storage does not hinder the quality or biological efficacy of the CBHPSC. PMID- 29460119 TI - Curcumin Inhibits Monocyte Chemoattractant Protein-1 Expression in TNF-alpha induced Astrocytes Through AMPK Pathway. AB - Curcumin, a phenolic pigment, plays an inhibitory role in astrocytes activation, a key step for neuropathic pain (NP). The present study aimed to investigate the mechanism behind the therapeutic effect of Curcumin on NP in vitro. Specifically, we investigated the inhibitory effect of Curcumin on tumor necrosis factor-alpha (TNF-alpha)-induced astrocyte migration. We also studied the effects of Curcumin on monocyte chemoattractant protein-1(MCP-1) expression and activity, as well as super oxide dismutase-2 (SOD2) expression and activity in TNF-alpha-induced astrocytes. Additionally, we investigated whether the adenosine-monophosphate activated protein kinase signaling (AMPK) pathway was involved in this process. Our data demonstrated that Curcumin inhibited TNF-alpha-induced astrocytes migration, decreased MCP-1 expression, and up-regulated SOD2 expression in TNF alpha-induced astrocytes in vitro. Our study also indicated that this process was mediated through the AMPK signaling pathway, as addition of Curcumin significantly increased the level of phosphorylated AMPK protein. Furthermore, the specific AMPK activator AICAR (5-aminoimidazole-4-carboxamide 1-D ribofuranoside) mimicked the effects of Curcumin, whereas a selective AMPK inhibitor Compound C (also called dorsomorphin) partially blocked its function. These results could shed light on understanding of the molecular basis for the inhibition of Curcumin on MCP-1 expression during the process of astrocyte activation, and provide a molecular mechanism for using Curcumin in neuropathic pain. PMID- 29460120 TI - New Insights into CO2 Adsorption on Layered Double Hydroxide (LDH)-Based Nanomaterials. AB - The interlamellar spacing of layered double hydroxides (LDHs) was enlarged by dodecyl sulfonate ions firstly, and then, (3-aminopropyl)triethoxysilane (APS) was chemically grafted (APS/LDHs). The structural characteristics and thermal stability of these prepared samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), reflectance Fourier transform infrared spectrometer (FTIR), thermogravimetric analysis (TG), and elemental analysis (EA) respectively. The CO2 adsorption performance was investigated adopting TG and diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS). The results presented that the CO2 adsorption capacity on APS/LDHs was as high as 90 mg/g and showed no obvious reduction during a five cyclic adsorption-desorption test, indicating its superior performance stability. The DRIFTS results showed that both carbamates and weakly bounded CO2 species were generated on APS/LDHs. The weakly adsorbed species was due to the different local chemical environment for CO2 capture provided by the surface moieties of LDHs like free silanol and hydrogen bonds. PMID- 29460121 TI - PACAP and its receptors in cranial arteries and mast cells. AB - BACKGROUND: In migraineurs pituitary adenylate cyclase activating peptide1-38 (PACAP1-38) is a potent migraine provoking substance and the accompanying long lasting flushing suggests degranulation of mast cells. Infusion of the closely related vasoactive intestinal peptide (VIP) either induces headache or flushing. This implicates the pituitary adenylate cyclase activating peptide type I receptor (PAC1) to be involved in the pathophysiology of PACAP1-38 provoked headaches. Here we review studies characterizing the effects of mainly PACAP but also of VIP on cerebral and meningeal arteries and mast cells. DISCUSSION: PACAP1 38, PACAP1-27 and VIP dilate cerebral and meningeal arteries from several species including man. In rat cerebral and meningeal arteries the dilation seems to be mediated preferably via vasoactive intestinal peptide receptor type 1 (VPAC1) receptors while, in human, middle meningeal artery dilation induced via vasoactive intestinal peptide receptor type 2 (VPAC2) receptors cannot be ruled out. PACAP1-38 is a strong degranulator of peritoneal and dural mast cells while PACAP1-27 and VIP only have weak effects. More detailed characterization studies suggest that mast cell degranulation is not mediated via the known receptors for PACAP1-38 but rather via a still unknown receptor coupled to phospholipase C. CONCLUSION: It is suggested that PACAP1-38 might induce migraine via degranulation of dural mast cells via a yet unknown receptor.

PMID- 29460124 TI - Accuracy of cardiac CT in evaluating severity of left atrial appendage spontaneous echo contrast: comparison with transesophageal echocardiography. AB - To investigate the capacity of biphasic cardiac CT (CCT) for qualitative and quantitative evaluation of different grades of left atrial appendage spontaneous echo contrast (LAASEC). The study included 267 inpatients with confirmed atrial fibrillation who underwent both CCT and transesophageal echocardiography (TEE). CT numbers for LAA, ascending aorta (AA), and left atrium (LA) were identified, and ROC curves for LAA, LAA/AA, and LAA/LA were plotted. With TEE as the standard, the sensitivity, specificity, PPV, NPV, and accuracy of CCT for LAASEC grade >= 1 were 60.3, 92.9, 92.4, 64.8, and 75.7%; and for grade >= 2 were 100.0, 84.4, 71.4, 100.0, and 88.8% respectively. The values of LAA, LAA/AA, and LAA/LA were significantly larger in LAASEC grade 0 versus 1 and in grade 1 versus 2, but were similar in grades 2 and 3 or in grades 3 and 4. The values of LAA/AA were larger in grade 2 versus 4. When the cutoff value for LAA/AA = 0.897, sensitivity, specificity, PPV, NPV, and accuracy of CCT for LAASEC grade >= 1 was 89.6, 83.2, 87.9, 85.5, and 86.9% and with a cutoff for LAA/AA of 0.524, the sensitivity, specificity, PPV, NPV, and accuracy for LAASEC grade >= 2 was 98.7, 92.7, 84.1, 99.4, and 94.4%. Although CCT showed limited diagnostic accuracy for grade 1 LAASEC, grade >= 2 LAASEC could be excluded when there was no LAA filling defect on first-phase CCT, and TEE can be avoided. CCT has an excellent accuracy in diagnosing LAASEC, and quantitative analysis (in particular LAA/AA) is superior. PMID- 29460125 TI - Bile duct angulation and tumor vascularity are useful radiographic features for differentiating pancreatic head cancer and intrapancreatic bile duct cancer. AB - BACKGROUND AND PURPOSE: To perform radical resection without leaving residual cancer, surgeons must distinguish between pancreatic head cancer (PHC) and intrapancreatic bile duct cancer (IPBDC) preoperatively. The aim of this study was to establish the points of difference between these two cancers, especially on preoperative multi-detector computed tomography (MDCT) images. METHODS: The subjects of this study were 28 patients with PHC and proven bile duct invasion who underwent pancreatoduodenectomy (PHC group) and 22 patients with IPBDC and upstream bile duct dilation (IPBDC group). We compared the preoperative clinical and radiographic features, including the bile duct angle, calculated on coronal images of MDCT, and the vascularity of the tumor. RESULTS: The optimal cut-off values for the bile duct angle, the CT value ratio of the tumor (late arterial phase/non-enhanced), and the main pancreatic duct (MPD) ratio (diameter of MPD/diameter of parenchyma) were 110 degrees , 3.0, and 0.2, respectively. Multivariate analysis revealed that a bile duct angle < 110 degrees , a CT value ratio of the tumor < 3, and an MPD ratio >= 0.2 were independently associated with PHC. CONCLUSIONS: A bile duct angle and CT value reflecting the vascularity of the tumor might be useful radiographic features for differentiating PHC and IPBDC, in addition to MPD dilatation. PMID- 29460126 TI - Incidence and treatment of metachronous gastric cancer after proximal gastrectomy. AB - BACKGROUND AND PURPOSE: Proximal gastrectomy (PG) is a widely accepted function preserving surgical procedure; however, the incidence and treatment of metachronous gastric cancer (MGC) after PG have been the subject of a number of reports. METHODS: We collected data from 1576 consecutive patients who underwent gastrectomy for gastric cancer between January, 2003 and December, 2010, and analyzed the outcomes of 671 patients treated with PG or distal gastrectomy (DG) for cT1N0 disease. We also discuss the treatments for MGC. RESULTS: MGC was diagnosed within a median follow-up of 52.8 months after PG and DG in six (6.6%) and nine (1.8%) patients, respectively. The cumulative prevalence of MGC after PG was significantly higher than that after DG; P = 0.005. Univariate and multivariate analysis revealed male sex and PG as significant risk factors for MGC (P = 0.014 and P = 0.026, respectively). Five of the six patients who underwent PG were treated by endoscopic submucosal dissection. CONCLUSIONS: The incidence of MGC after PG was significantly higher than that after DG. However, most of the MGCs that developed after PG could be treated by endoscopic submucosal dissection. PMID- 29460123 TI - Warning SINEs: Alu elements, evolution of the human brain, and the spectrum of neurological disease. AB - Alu elements are a highly successful family of primate-specific retrotransposons that have fundamentally shaped primate evolution, including the evolution of our own species. Alus play critical roles in the formation of neurological networks and the epigenetic regulation of biochemical processes throughout the central nervous system (CNS), and thus are hypothesized to have contributed to the origin of human cognition. Despite the benefits that Alus provide, deleterious Alu activity is associated with a number of neurological and neurodegenerative disorders. In particular, neurological networks are potentially vulnerable to the epigenetic dysregulation of Alu elements operating across the suite of nuclear encoded mitochondrial genes that are critical for both mitochondrial and CNS function. Here, we highlight the beneficial neurological aspects of Alu elements as well as their potential to cause disease by disrupting key cellular processes across the CNS. We identify at least 37 neurological and neurodegenerative disorders wherein deleterious Alu activity has been implicated as a contributing factor for the manifestation of disease, and for many of these disorders, this activity is operating on genes that are essential for proper mitochondrial function. We conclude that the epigenetic dysregulation of Alu elements can ultimately disrupt mitochondrial homeostasis within the CNS. This mechanism is a plausible source for the incipient neuronal stress that is consistently observed across a spectrum of sporadic neurological and neurodegenerative disorders.

PMID- 29460128 TI - Molecular characterization of Plum pox virus Rec isolates from Russia suggests a new insight into evolution of the strain. AB - Field isolates of Plum pox virus (PPV), belonging to the strain Rec, have been found for the first time in Russia. Full-size genomes of the isolates K28 and Kisl-1pl from myrobalan and plum, respectively, were sequenced on the 454 platform. Analysis of all known PPV-Rec complete genomes using the Recombination Detection Program (RDP4) revealed yet another recombination event in the 5' terminal region. This event was detected by seven algorithms, implemented in the RDP4, with statistically significant P values and supported by a phylogenetic analysis with the bootstrap value of 87%. A putative PPV-M-derived segment, encompassing the C-terminus of the P1 gene and approximately two-thirds of the HcPro gene, is bordered by breakpoints at positions 760-940 and 1838-1964, depending on the recombinant isolate. The predicted 5'-distal breakpoint for the isolate Valjevka is located at position 2804. The Dideron (strain D) and SK68 (strain M) isolates were inferred as major and minor parents, respectively. Finding of another recombination event suggests more complex evolutionary history of PPV-Rec than previously assumed. Perhaps the first recombination event led to the formation of a PPV-D variant harboring the PPV-M-derived fragment within the 5'-proximal part of the genome. Subsequent recombination of its descendant with PPV-M in the 3'-proximal genomic region resulted in the emergence of the evolutionary successful strain Rec.

AB - : Structured reporting is emerging as a key element of optimising radiology's contribution to patient outcomes and ensuring the value of radiologists' work. It is being developed and supported by many national and international radiology societies, based on the recognised need to use uniform language and structure to accurately describe radiology findings. Standardisation of report structures ensures that all relevant areas are addressed. Standardisation of terminology prevents ambiguity in reports and facilitates comparability of reports. The use of key data elements and quantified parameters in structured reports ("radiomics") permits automatic functions (e.g. TNM staging), potential integration with other clinical parameters (e.g. laboratory results), data sharing (e.g. registries, biobanks) and data mining for research, teaching and other purposes. This article outlines the requirements for a successful structured reporting strategy (definition of content and structure, standard terminologies, tools and protocols). A potential implementation strategy is outlined. Moving from conventional prose reports to structured reporting is endorsed as a positive development, and must be an international effort, with international design and adoption of structured reporting templates that can be translated and adapted in local environments as needed. Industry involvement is key to success, based on international data standards and guidelines. KEY POINTS: * Standardisation of radiology report structure ensures completeness and comparability of reports. * Use of standardised language in reports minimises ambiguity. * Structured reporting facilitates automatic functions, integration with other clinical parameters and data sharing. * International and inter society cooperation is key to developing successful structured report templates. * Integration with industry providers of radiology-reporting software is also crucial.

AB - We used the World Health Organization's Composite International Diagnostic Interview to determine the prevalence, comorbidity, and correlates of lifetime and 12-month behavioral health disorders in a multisite cohort of 1027 women living with HIV in the United States. Most (82.6%) had one or more lifetime disorders including 34.2% with mood disorders, 61.6% with anxiety disorders, and 58.3% with substance use disorders. Over half (53.9%) had at least one 12-month disorder, including 22.1% with mood disorders, 45.4% with anxiety disorders, and 11.1% with substance use disorders. Behavioral health disorder onset preceded HIV diagnosis by an average of 19 years. In multivariable models, likelihood of disorders was associated with women's race/ethnicity, employment status, and income. Women with 12-month behavioral health disorders were significantly more likely than their counterparts to engage in subsequent sexual and substance use HIV risk behaviors. We discuss the complex physical and behavioral health needs of women living with HIV. PMID- 29460132 TI - The role of HCN channels in peristaltic dysfunction in human ureteral tuberculosis. AB - OBJECTIVE: To explore the role of HCN channels in ureteral peristaltic dysfunction by comparing the changes in HCN channel levels between normal and tuberculous ureters. METHODS: A total of 32 specimens of human upper ureters were collected by nephrectomy from patients with renal tumor (control group, n = 16) or from patients with renal tuberculosis (experimental group, n = 16); the two groups did not receive radiotherapy, chemotherapy, immunotherapy, or any other special treatment before the surgical procedure. An experimental study on smooth muscle strips of human upper ureters showed variation in contraction amplitude and frequency after adding ZD7288, a specific blocker of HCN channels. The expression of HCN channels in the ureter was confirmed by Western blot (WB) and by confocal analysis of double immunostaining for c-kit and HCN channel proteins. RESULTS: Before the addition of ZD7288, the experimental and control groups showed significant differences in the frequency and amplitude of the spontaneous contraction of isolated ureteral smooth muscle strips. After ZD7288 was added, the frequency and amplitude of the contractions of the ureteral smooth muscle strips were significantly lower in both groups. The differences observed before and after ZD7288 treatment in each group were significant (P < 0.001), and the difference in contraction amplitude observed between the two groups before ZD7288 was also significantly different (P < 0.001). By using WB technology, we showed that the expression of HCN channels was present in normal human ureters, with the expression of HCN4 and HCN1 being the highest; the expression of HCN4 and HCN1 in the control and experimental groups were both statistically significant (P < 0.001). HCN4 and HCN1 were expressed in the mucosal and smooth muscle layers of human control ureters and tuberculous ureters, as revealed by a confocal analysis of double immunostaining for c-kit and HCNs proteins; there were significant differences between the two groups (P < 0.001). CONCLUSION: Four HCN channels are expressed in the ureter, mainly HCN4 and HCN1, suggesting that HCN channels are involved in the peristaltic contraction of ureteral ICCs, which may be an important reason for peristaltic dysfunction in ureteric tuberculosis. PMID- 29460131 TI - Inhibiting autophagy overcomes docetaxel resistance in castration-resistant prostate cancer cells. AB - BACKGROUND: This study investigates the docetaxel-resistant mechanism and explores the effect of tea polyphenols (TP) on autophagy and its related mechanism in human castration-resistant prostate cancer (CRPC) cell lines PC3 and DU145. METHODS: Immunofluorescence assay and annexin V-FITC/PI double staining flow cytometry were used to analyze the apoptosis and autophagy of PC3 and DU145 cells. The expression of autophagy-related proteins was detected by western bolt. RESULTS: Docetaxel could induce autophagy and apoptosis, together with the expression increase in p-JNK, p-Bcl-2 and Beclin1. The level of autophagy was remarkably decreased, but apoptosis was increased after combining with TP. In addition, the expression of p-mTOR was increased after combining with TP. CONCLUSION: Docetaxel induces protective autophagy in CRPC cells by JNK pathway activation and then Bcl-2 phosphorylation and Beclin1 dissociation. TP activates mTOR pathway, which ultimately inhibits docetaxel-induced autophagy and improves therapeutic efficacy of docetaxel in CRPC cells.

AB - OBJECTIVES: To investigate the efficacy of insulin sensitizer on prostatic tissue in animal model with benign prostatic hyperplasia (BPH) secondary to metabolic syndrome (MetS). METHODS: Models were established by providing Sprague-Dawley rats with high fat diet (HFD) combined with metformin or not. All objects were killed 40 days later with prostatic tissue being removed, weighed before stained, as well as the expression level of insulin-like growth factor I (IGF-1) and receptor (IGF-1R) being measured, and the level of insulin resistance (IR) has also been evaluated. RESULTS: Model has been successfully established. Level of prostatic hyperplasia and IR as well as IGF-1 and IGF-1R expressions in the blank and saline control subunits of HFD group was higher than that of normal diet group (P < 0.05). In the subunit of metformin, along with the suppression of IR, the level of prostatic hyperplasia and the expression of IGF-1 pathway have both decreased (P < 0.05). CONCLUSION: MetS can promote the growth of prostate during the formation of central obesity and IR. IGF-1 pathway may have an important role in the induction of BPH following IR. The application of metformin can suppress the expression of IGF-1 and IGF-1R, thus preventing the promotive effect of IR on prostate tissue in animal model of MetS.

AB - The present study examined the role of anxiety sensitivity (AS; fear of the negative consequences of anxiety) in the relation between perceived racial discrimination and pain-related problems among Latinos seeking health services at a Federally Qualified Health Center. Participants included 145 adult Latinos (87.80% female, Mage = 38.07 years, SD = 11.98, and 96.2% reported Spanish as their first language). Results indicated that perceived racial discrimination was indirectly related to the pain intensity and pain disability through AS. These effects were evident above and beyond the variance accounted for by gender, age, marital status, educational status, employment status, years living in the United States, and number of axis I diagnoses. Overall, the present findings highlight the merit in focusing further scientific attention on the interplay between perceived racial discrimination and AS to better understand and inform interventions to reduce pain problems among Latinos in primary care. PMID- 29460135 TI - Simvastatin reduces adrenal catecholamine secretion evoked by stimulation of cholinergic nicotinic and angiotensinergic AT1 receptors. AB - We investigated the influence of simvastatin, a statin, on the secretion of catecholamines (CA) in rat adrenal glands, and clarified its action mechanism. Simvastatin suppressed acetylcholine (ACh)-evoked CA release in a dose- and time dependent fashion. In the presence of simvastatin, CA secretion evoked by 1.1 dimethyl-4-phenyl piperazinium iodide (DMPP), angiotensin II, high K+, veratridine, and Bay-K-8644 was time-dependently inhibited. However, in the simultaneous presence of simvastatin and Nomega-nitro-L-arginine methyl ester hydrochloride, CA secretion evoked by angiotensin II and DMPP recovered to control levels. Adrenal NO release was increased by simvastatin-treatment. Simvastatin-inhibited CA secretion was not affected by treatment with mevalonate. Pravastatin did not influence ACh-evoked CA secretion, while atorvastatin reduced it. In the simultaneous presence of simvastatin and fimasartan, ACh-induced CA release was markedly reduced compared to that of fimasartan-treatment alone. We present the first evidence that simvastatin reduces adrenal CA secretion induced by stimulation of nicotinic and AT1-receptors. Simvastatin-induced inhibition seems to involve reducing the influx of both Ca2+ and Na+ into adrenochromaffin cells, partly via the elevation of NO production by NO synthase activation, without inhibition of 3-hydroxy-methylglutaryl coenzyme A reductase. Co administration of simvastatin and fimasartan may be clinically helpful for the treatment of cardiovascular diseases.

AB - Rodents are intermediate hosts for many species of Sarcocystis. Little is known of Sarcocystis cymruensis that uses the Brown rat (Rattus norvegicus) as intermediate hosts and the domestic cat (Felis catus) as experimental definitive host. Here, we identified and described Sarcocystis cymruensis in naturally infected R. norvegicus from Grenada, West Indies. Rats (n = 167) were trapped in various locations in two parishes (St. George and St. David). Microscopic, thin (< 1 MUm) walled, slender sarcocysts were found in 11 of 156 (7.0%) rats skeletal muscles by squash examination. A laboratory-raised cat fed naturally infected rat tissues excreted sporocysts that were infectious for interferon gamma gene knockout (KO) mice, but not to Swiss Webster outbred albino mice. All inoculated mice remained asymptomatic, and microscopic S. cymruensis-like sarcocysts were found in the muscles of KO mice euthanized on day 70, 116, and 189 post inoculation (p.i.). Sarcocysts from infected KO mice were infective for cats at day 116 but not at 70 days p.i. By transmission electron microscopy, the sarcocyst wall was "type 1a." Detailed morphological description of the cyst wall, metrocytes, and bradyzoites is given for the first time. Additionally, molecular data on S. cymruensis are presented also for the first time. Molecular characterization of sarcocysts 18S rDNA and 28S rDNA, ITS-1, and cox1 loci showed the highest similarity with S. rodentifelis and S. muris. In conclusion, the present study described the natural infection of S. cymruensis in Brown rat for the first time in a Caribbean country and provided its molecular characteristics. PMID- 29460141 TI - Complete Restitution of the Ischemic Penumbra after Successful Thrombectomy : A Pilot Study Using Quantitative MRI. AB - PURPOSE: Endovascular thrombectomy is highly effective in patients with proximal large artery occlusion but the relevance of reperfusion injury after recanalization is a matter of debate. The aim of this study was to investigate potential residual metabolic distress and microstructural tissue damage or edema after reperfusion using quantitative oxygen-sensitive T2' and T2-mapping in patients successfully treated by thrombectomy. METHODS: Included in this study were 11 patients (mean age 70 +/- 11.4 years) with acute ischemic stroke due to internal carotid artery and/or middle cerebral artery occlusion. Quantitative T2 and T2' (1/T2' = 1/T2* - 1/T2) were determined within the ischemic core and hypoperfused but salvaged tissue with delayed time-to-peak (TTP) in patients before and after successful thrombectomy and compared to a control region within the unaffected hemisphere. RESULTS: Decreased T2' values within hypoperfused tissue before thrombectomy showed a normalization after recanalization (p < 0.01). In formerly hypoperfused but salvaged tissue, T2 values increased significantly after thrombectomy (p < 0.05) but did not differ from reference values in the control region. In salvaged tissue, increases of quantitative T2' and T2 to follow-up were more pronounced in areas with severe TTP delay. CONCLUSION: After successful recanalization, T2' re-increased back to normal in formerly hypoperfused areas as a sign of prompt normalization of oxygen metabolism. Furthermore, quantitative T2 in the formerly hypoperfused tissue did not differ from reference values in unaffected tissue. These results indicate complete restitution of salvaged tissue after reperfusion and support the overall safety of endovascular thrombectomy with respect to microstructural tissue integrity. PMID- 29460142 TI - Investigation of Neurodegenerative Processes in Amyotrophic Lateral Sclerosis Using White Matter Fiber Density. AB - In the current work two novel parameters, fiber density (FD) and mean diffusion signal (MDS) are investigated for evaluating neurodegenerative processes in amyotrophic lateral sclerosis (ALS). The MDS provides a measure of the FD but is derived directly from the diffusion signal. Using tract-based spatial statistics (TBSS), pathological changes across the entire white matter and changes in the parameters over time were evaluated. The results were related to those obtained using the fractional anisotropy (FA) value. A widespread pattern of significantly decreased FD and MDS values was observed. A strong trend towards statistical significance was seen in similar white matter structures using TBSS analysis based on the FA value. Longitudinal analysis of the FD values demonstrated continuing deterioration of the same fiber tracts that were shown to be impaired in the group analysis. The findings suggest that MDS and in particular FD show great promise for evaluating microstructural white matter changes in ALS and may be more sensitive than the more commonly used FA value. PMID- 29460143 TI - Listening in the bog: II. Neural correlates for acoustic interactions and spacing between Sphagniana sphagnorum males. AB - Males of the katydid Sphagniana sphagnorum maintain inter-male distances from one another using agonistic song interactions with a frequency-modulated song that consists of alternating audio and ultrasonic parts. We studied the neuronal representation of this song in auditory receptors and interneurons of receivers, using playbacks of songs that mimicked the absolute and relative sound pressure levels of the two song modes varying with distance. The tuning and sensitivity of both receptors and interneurons strongly determine their responses to the two song modes at different distances. Low-frequency interneurons respond preferentially to the audio mode of the song at larger distances. High-frequency (HF) interneurons respond preferentially to the HF component of the song at close range. 'Switch interneurons' are sensitive to both spectral song components, but exhibit a typical activity switch towards the high-frequency mode at distances nearer than 3-6 m. The activity of the latter two groups of interneurons correlates with the distance in the field at which males begin to interact acoustically with their neighbours. Important information about the rate of changes in the song mode is represented by the afferent activity despite the influence of the masking song produced by a sympatric katydid species. PMID- 29460144 TI - Negative errors in time reproduction tasks. AB - In time reproduction tasks, the reaction time of motor responses is intrinsically linked to the measure of perceptual timing. Decisions are based on a continuous comparison between elapsed time and a memory trace of the to-be-reproduced interval. Here, we investigate the possibility that negative reproduction errors can be explained by the tendency to prefer earlier over later response times, or whether the whole range of possible response times is shifted. In experiment 1, we directly compared point reproduction (participants indicate the exact time point of equality) and range reproduction (participants bracket an interval containing this time point). In experiment 2, participants indicated, in three separate tasks, the exact time point at which the reproduction phase was equal to the standard duration (point reproduction), the earliest (start reproduction), or the latest moment (stop reproduction) at which the exact time point of equality might have been reached. The results demonstrate that the bias towards earlier responses not only affects reproduction of the exact time point of equality. Rather, even if the decision threshold is changed in favor of late responses, they exhibit a continuous shift towards negative errors that increases with the length of the standard duration. The findings are discussed in the context of the hypothesis that systematic errors in time reproduction tasks reflect a dimension unspecific tendency towards earlier responses caused by the psychophysical method rather than by a time-specific perceptual distortion. PMID- 29460145 TI - A Paper-Based Analytical Device Based on Combination of Thin Film Microextraction and Reflection Scanometry for Sensitive Colorimetric Determination of Ni(II) in Aqueous Matrix. AB - In this research, the thin film microextraction method was applied for the extraction of Ni(II) ion from aqueous matrixes. Chemically modified cellulosic filter paper with phosphorus was used as a thin film extractor. After extraction, the thin film was treated with a solution of dimethylglyoxime. The colored film was captured by flatbed scanner and the absorbance of the images was extracted by some suitable software. Under the optimum conditions and at the pH 7.0, with the sample volume of 100 mL, the stirring rate of 800 rpm, and the extraction time of 50 min, the calibration curve was obtained in the range of 0.05-5 mg/L Ni(II) (R2 = 0.989). Limit and relative standard deviation were achieved to be 18 ug/L and less than 6.7%, respectively. Relative recoveries were obtained in the range of 87%-105%. Finally, the proposed method was found to be simple and cost-effective, with adequate analytical performance for the rapid detection of Ni(II) in river and wastewater samples. PMID- 29460146 TI - Sex-specific thermal sensitivities of performance and activity in the asian house gecko, Hemidactylus frenatus. AB - Studies of sexual selection primarily focus on morphological traits such as body size and secondary trait dimorphism, with less attention been given to the functional differences between the sexes and even more so their thermal performance capacities. Each sex may benefit from possessing different thermal performance capacities that would allow them to maximise their fitness relative to their different reproductive roles; especially when performances are closely related to reproductive success. Here, we examine sexual divergence in thermal sensitivities of performance across three populations of the Asian house gecko (Hemidactylus frenatus) over an extensive latitudinal cline. Using analyses of the thermal sensitivity of routine activity, bite force and sprint speed, we explored whether: (i) males and females differed in their optimal temperatures for performance, (ii) the sexes differed in their thermal sensitivities of performance, and (iii) the degree of sexual divergence in thermal sensitivity varied among the populations. Because male H. frenatus are highly aggressive and frequently engage in combat to gain territories and mating opportunities, we expected males would be active over a wider range of temperatures than females and this would favour broad thermal sensitivity curves for males. In addition, we expected a greater divergence between the sexes in thermal sensitivities for the temperate populations that experience greater daily and seasonal thermal variation. We found that males were more active, and had greater bite forces and faster sprint speeds than females, independent of body size. In addition, we found differences between the sexes in thermal sensitivities for the tropical population; female H. frenatus were less active and possessed lower sprint speeds at higher temperatures than males. Although H. frenatus from the most variable thermal environments also displayed the broadest thermal performance range, it was the more stable tropical population that exhibited the greatest divergence between the sexes in thermal sensitivity of performance. The divergence in thermal physiology that we detected between the sexes of H. frenatus is consistent with the idea that males will derive mating and territorial advantages for maintaining function over a broader range of temperatures.

AB - OBJECTIVE: To determine if patients with rheumatoid arthritis (RA) are at risk of vitamin D deficiency and whether the levels of vitamin D are correlated with clinical parameters in RA. METHODS: A total of 280 treatment-naive RA patients, and 140 age- and sex-matched healthy volunteers were enrolled. Serum levels of 1,25-dihydroxycholecalciferol (1,25(OH)2D3), the active form of vitamin D, were measured by enzyme-linked immunosorbent assay (ELISA). Concentrations of 1,25(OH)2D3 less than 25 ng/mL were defined as insufficient. Linear regression was performed to evaluate correlations as (modifying and) confounding factors were controlled. RESULTS: The levels of serum 1,25(OH)2D3 in RA individuals (12.24 +/- 6.68 ng/ml) were significantly lower than in healthy controls (21.08 +/- 7.14 ng/ml; p < 0.05). An inverse association was found between the levels of 1,25(OH)2D3 and ESR in obese and overweight individuals with RA (betaobese = 0.385, betaoverweight = -0.395, both p < 0.05), but not in normal and underweight subjects. A significant negative association between levels of 1,25(OH)2D3 and DAS28 score (beta = -0.164, p = 0.018) was observed. The levels of 1,25(OH)2D3 were associated moderately and inversely with the absolute numbers of Th-17 (beta = -0.158, p = 0.019) and positively with those of CD4+ regulatory T (Treg) cell (beta = 0.146, p = 0.025). The levels of 1,25(OH)2D3 in anti-cyclic citrullinated peptide (anti-CCP)-positive patients with RA were lower than in the anti-CCP negative RA patients (10.86 ng/ml versus 15.98 ng/ml; t = -3.08, p < 0.01). CONCLUSIONS: A significant association was observed between levels of vitamin D and parameters of disease, including body mass index (BMI), DAS28, Th17 cell counts, Treg cell counts, and presence of anti-CCP antibody in RA patients. PMID- 29460147 TI - Self-reported history of stroke and long-term living conditions near air pollution sources: results of a national epidemiological study in Lebanon. AB - Stroke is a disease related to high mortality and morbidity, particularly in developing countries. Some studies have linked self-reported indoor and outdoor pollution to stroke and mini-stroke, while some others showed no association. Our objective was to assess this association in Lebanon, a Middle Eastern developing country. A national cross-sectional study was conducted all over Lebanon. In addition to self-reported items of pollution exposure, we assessed potential predictors of stroke and mini-stroke, including sociodemographic characteristics, self-reported health information, and biological measurements. Moreover, we assessed dose-effect relationship of pollution items in relation with stroke. Self-reported indoor pollution exposure was associated with stroke and mini stroke, with or without taking biological values into account. Moreover, we found a dose-effect relationship of exposure with risk of disease, but this effect did not reach statistical significance after adjustment for sociodemographics and biological characteristics. No association was found for any outdoor pollution item. Although additional studies would be necessary to confirm these findings, sensitizing the population about the effect of pollution on chronic diseases, working on reducing pollution, and improving air quality should be implemented to decrease the burden of the disease on the population and health system. PMID- 29460149 TI - Inferring causal relationships between phenotypes using summary statistics from genome-wide association studies. AB - Genome-wide association studies (GWAS) have successfully identified numerous genetic variants associated with diverse complex phenotypes and diseases, and provided tremendous opportunities for further analyses using summary association statistics. Recently, Pickrell et al. developed a robust method for causal inference using independent putative causal SNPs. However, this method may fail to infer the causal relationship between two phenotypes when only a limited number of independent putative causal SNPs identified. Here, we extended Pickrell's method to make it more applicable for the general situations. We extended the causal inference method by replacing the putative causal SNPs with the lead SNPs (the set of the most significant SNPs in each independent locus) and tested the performance of our extended method using both simulation and empirical data. Simulations suggested that when the same number of genetic variants is used, our extended method had similar distribution of test statistic under the null model as well as comparable power under the causal model compared with the original method by Pickrell et al. But in practice, our extended method would generally be more powerful because the number of independent lead SNPs was often larger than the number of independent putative causal SNPs. And including more SNPs, on the other hand, would not cause more false positives. By applying our extended method to summary statistics from GWAS for blood metabolites and femoral neck bone mineral density (FN-BMD), we successfully identified ten blood metabolites that may causally influence FN-BMD. We extended a causal inference method for inferring putative causal relationship between two phenotypes using summary statistics from GWAS, and identified a number of potential causal metabolites for FN-BMD, which may provide novel insights into the pathophysiological mechanisms underlying osteoporosis. PMID- 29460150 TI - pH Modulation of Voltage-Gated Sodium Channels. AB - Changes in blood and tissue pH accompany physiological and pathophysiological conditions including exercise, cardiac ischemia, ischemic stroke, and cocaine ingestion. These conditions are known to trigger the symptoms of electrical diseases in patients carrying sodium channel mutations. Protons cause a diverse set of changes to sodium channel gating, which generally lead to decreases in the amplitude of the transient sodium current and increases in the fraction of non inactivating channels that pass persistent currents. These effects are shared with disease-causing mutants in neuronal, skeletal muscle, and cardiac tissue and may be compounded in mutants that impart greater proton sensitivity to sodium channels, suggesting a role of protons in triggering acute symptoms of electrical disease.In this chapter, we review the mechanisms of proton block of the sodium channel pore and a suggested mode of action by which protons alter channel gating. We discuss the available data on isoform specificity of proton effects and tissue level effects. Finally, we review the role that protons play in disease and our own recent studies on proton-sensitizing mutants in cardiac and skeletal muscle sodium channels. PMID- 29460151 TI - Sphingosine Kinases as Druggable Targets. AB - There is substantial evidence that the enzymes, sphingosine kinase 1 and 2, which catalyse the formation of the bioactive lipid sphingosine 1-phosphate, are involved in pathophysiological processes. In this chapter, we appraise the evidence that both enzymes are druggable and describe how isoform-specific inhibitors can be developed based on the plasticity of the sphingosine-binding site. This is contextualised with the effect of sphingosine kinase inhibitors in cancer, pulmonary hypertension, neurodegeneration, inflammation and sickling. PMID- 29460152 TI - Cystic Fibrosis, Cystic Fibrosis Transmembrane Conductance Regulator and Drugs: Insights from Cellular Trafficking. AB - The eukaryotic cell is organized into membrane-delineated compartments that are characterized by specific cadres of proteins sustaining biochemically distinct cellular processes. The appropriate subcellular localization of proteins is key to proper organelle function and provides a physiological context for cellular processes. Disruption of normal trafficking pathways for proteins is seen in several genetic diseases, where a protein's absence for a specific subcellular compartment leads to organelle disruption, and in the context of an individual, a disruption of normal physiology. Importantly, several drug therapies can also alter protein trafficking, causing unwanted side effects. Thus, a deeper understanding of trafficking pathways needs to be appreciated as novel therapeutic modalities are proposed. Despite the promising efficacy of novel therapeutic agents, the intracellular bioavailability of these compounds has proved to be a potential barrier, leading to failures in treatments for various diseases and disorders. While endocytosis of drug moieties provides an efficient means of getting material into cells, the subsequent release and endosomal escape of materials into the cytosol where they need to act has been a barrier. An understanding of cellular protein/lipid trafficking pathways has opened up strategies for increasing drug bioavailability. Approaches to enhance endosomal exit have greatly increased the cytosolic bioavailability of drugs and will provide a means of investigating previous drugs that may have been shelved due to their low cytosolic concentration. PMID- 29460153 TI - GABA and Glutamate Synaptic Coadaptations to Chronic Ethanol in the Striatum. AB - Alcohol (ethanol) is a widely used and abused drug with approximately 90% of adults over the age of 18 consuming alcohol at some point in their lifetime. Alcohol exerts its actions through multiple neurotransmitter systems within the brain, most notably the GABAergic and glutamatergic systems. Alcohol's actions on GABAergic and glutamatergic neurotransmission have been suggested to underlie the acute behavioral effects of ethanol. The striatum is the primary input nucleus of the basal ganglia that plays a role in motor and reward systems. The effect of ethanol on GABAergic and glutamatergic neurotransmission within striatal circuitry has been thought to underlie ethanol taking, seeking, withdrawal and relapse. This chapter reviews the effects of ethanol on GABAergic and glutamatergic transmission, highlighting the dynamic changes in striatal circuitry from acute to chronic exposure and withdrawal. PMID- 29460154 TI - Comparison of single versus two non-compression miniplates in the management of unfavourable angle fracture of the mandible: a prospective randomized clinical study. AB - PURPOSE: The purpose of this study was to compare the efficacy of single versus two non-compression miniplates in the management of unfavourable angle fracture of mandible. MATERIALS AND METHODS: A total of 28 patients who required open reduction of mandibular angle fracture were included in the study. The patients were randomly divided into two groups. Group I comprised of patients treated with two miniplates and those in group II were treated with single non-compression miniplate. The parameters of assessment were malocclusion, surgical site infection, need for implant removal, duration of surgery, inter-incisal mouth opening and cost of implants used, in both the groups. Statistical analysis was carried out to compare all the parameters. RESULTS: Out of 14 patients in group II, inadequate reduction was noticed in three patients, whereas screw loosening had occurred in two cases. Screw loosening was always associated with chronic infection. In these cases, hardware removal was deemed necessary. Plate bending was observed in two cases resulting in malocclusion and difficulty in eating. Non union of fracture occurred in one patient treated in group II. In group I, no plate bending, screw loosening, surgical site infection, non-union or malocclusion was observed. No patient had to undergo implant removal in group I. CONCLUSION: In the management of unfavourable mandibular angle fracture, two miniplates must be preferred over the use of single miniplate as using two miniplates results in better results with minimal complications. PMID- 29460155 TI - Pelvic reconstructions following peri-acetabular bone tumour resections using a cementless ice-cream cone prosthesis with dual mobility cup. AB - PURPOSE: Despite numerous reconstructive techniques and prosthetic devices, pelvic reconstructions following peri-acetabular malignant tumours resections are highly challenging. In the present study, we describe our experience with the Integra(r) (Lepine, Genay, France) ice-cream cone prosthesis in such indications. The objective was to assess the mid-term outcomes of this device. METHODS: Twenty four patients' chart with peri-acetabular malignant tumours, who underwent types II or II + III peri-acetabular resections according to Enneking and Dunham with subsequent reconstruction using the Integra(r) prosthesis between February 2009 and February 2015, were reviewed. Seventeen cases were primary surgeries and seven cases were revisions (i.e., failures of previous reconstructions for pelvic tumours). All living patients with the prosthesis implanted were functionally assessed, using the musculoskeletal tumour society (MSTS) and Postel-Merle d'Aubigne (PMA) scores. RESULTS: After a mean follow-up of 49 +/- 26 months (range, 8 to 94 months), 21 patients were alive (88%), including 15 patients continuously disease-free (63%). MSTS and PMA scores averaged 72 +/- 13% (range, 43 to 87%) and 14.6 +/- 2.6 (range, 9 to 18), respectively. Fourteen patients (58%) presented at least one complication during follow-up, including four cases of deep infection (17%), four cases of dislocation (17%), and two mechanical failures (8%). At 5 years, the implant survival rate was 75%. CONCLUSIONS: In comparison to previous reconstructive techniques that we used in similar indications, functional and oncologic outcomes were improved with the Integra(r) implant. However, as commonly observed in pelvic bone tumour surgery, complication rates remain significant. LEVEL OF EVIDENCE: Therapeutic, Level IV Retrospective Cases Series.

AB - Understanding the historical foundations of ethics in human research are key to illuminating future human research and clinical trials. This paper gives an overview of the most remarkable unethical human research and how past misconducts helped develop ethical guidelines on human experimentation such as The Nuremberg Code 1947 following WWII. Unethical research in the field of neuroscience also proved to be incredibly distressing. Participants were often left with life-long cognitive disabilities. This emphasizes the importance of implicating strict rules and ethical guidelines in neuroscience research that protect participants and respects their dignity. The experiments conducted by German Nazi in the concentration camps during WWII are probably the most inhumane and brutal ever conducted. The Nuremberg Code of 1947, one of the few positive outcomes of the Nazi experiments, is often considered the first document to set out ethical regulations of human research. It consists of numerous necessary criteria, to highlight a few, the subject must give informed consent, there must be a concrete scientific basis for the experiment, and the experiment should yield positive results that cannot be obtained in any other way. In the end, we must remember, the interest of the patient must always prevail over the interest of science or society.

AB - BACKGROUND AND AIMS: Esophageal food impaction (EFI) is a gastrointestinal emergency requiring immediate evaluation in the emergency room (ER) and an esophagogastroduodenoscopy (EGD) for disimpaction. EFI is also a distinct presenting feature of eosinophilic esophagitis (EoE). This study aimed at understanding the management of EFI among gastroenterologists (GIs) and estimated its impact on identification of EoE in USA. METHODS: GIs associated with three major gastroenterology societies based in USA were invited to participate in a web-based survey. Information on the resources available and utilized, and the clinical decision-making process related to management of EFI cases was collected and analyzed. RESULTS: Of 428 responses, 49% were from pediatric GIs, 86% practiced in the USA, and 78% practiced in an academic setting. Compared to the pediatric GIs, adult GIs were more likely to perform EGD in the emergency room [OR 87.96 (25.43-304.16)] and advance the food bolus into stomach [5.58 (3.08 10.12)]. Only 34% of respondents obtained esophageal biopsies during EGD, and pediatric GIs were more likely to obtain esophageal biopsies [3.49 (1.12-10.84)] compared to adult GIs. In USA, by our conservative estimates, 10,494 patients presenting to ER with EFI and at risk of EoE are likely being missed each year. CONCLUSIONS: EFI management varies substantially among GIs associated with three major gastroenterology societies in USA. Based on their practice patterns, the GIs in USA are likely to miss numerous EoE patients presenting to ER with EFI. Our findings highlight the need for developing and disseminating evidence-based EFI management practice guidelines.

AB - Patients with Parkinson's disease (PD) are compromised by poor oral condition due to oropharyngeal bradykinesia, dysphagia, and the side effects of treatment. Intrasalivary gland injections of Botulinum neurotoxin type A (BNT-A) have been known to treat sialorrhea effectively in these patients. However, the decreased amount of saliva reduces self-cleaning ability that deteriorates oral hygiene and increases dental caries. The aim of this study was to determine the changes in the oral microflora and saliva in patients with PD treated for sialorrhea by means of sonography-controlled BNT-A injections into the bilateral parotid and submandibular glands. Altogether, 38 persons participated in the study: 12 PD patients who were injected with BNT-A for treatment of sialorrhea and passed salivary tests before and 1 month after the injections; and 13 PD patients and 13 healthy subjects who were not injected with BNT-A and passed salivary tests once. The condition of oral health was measured by the amount of saliva, salivary flow rate, and salivary composition. A good outcome with a significant decrease in salivary flow rate occurred at 1-month follow-up in the BNT-A-treated group while no significant change was found in salivary composition. BNT-A treatment did not change the Streptococcus mutans levels in saliva but there was statistically significant increase in levels of Lactobacilli. BNT-A injections can effectively treat sialorrhea while considering the change of oral microflora, and the patients should be under dentists' care more frequently.

AB - Examining therapist evidence-based practice (EBP) knowledge seems an important step for supporting successful implementation. Advances in implementation science suggest a distinction between practice specific (i.e., knowing which practices are derived from the evidence base) and EBP process (i.e., integrating research evidence, clinical experience, client characteristics, and monitoring outcomes) knowledge. An examination of how these knowledge types are measured and relate to attitudes appears warranted. In our sample of 58 youth community therapists, both practice specific and EBP process knowledge accounted for EBP attitude scores, which varied by therapist demographic variables. Implications for measurement of therapist constructs and future research in identifying therapist predictors of EBP use and youth clinical improvement are discussed. PMID- 29460163 TI - Noradrenergic targets for the treatment of alcohol use disorder. AB - The role of norepinephrine (NE) in the development of alcohol use disorder (AUD) has been studied over the past several decades. However, the NE system has been largely ignored for many years as a potential target for medication development for AUD. More recently, preclinical and clinical studies have demonstrated the potential value of targeting NE signaling for developing new pharmacological treatments for AUD. This review contributes to a special issue of Psychopharmacology focused on promising targets for alcohol addiction. Specifically, this review coalesces preclinical and clinical neuroscience that re evaluate the noradrenergic system, and in particular the alpha-1 receptor, as a potential target for AUD. PMID- 29460164 TI - Assessing the risk of type 2 diabetes mellitus among children and adolescents with psychiatric disorders treated with atypical antipsychotics: a population based nested case-control study. AB - To examine the associations between atypical antipsychotic (AAP) exposure and the development of type 2 diabetes mellitus (T2DM) in Korean pediatric patients with psychiatric disorders, we conducted a nested case-control study using the claims data of the National Health Insurance system of Korea between 2010 and 2014. A cohort of patients with psychiatric disorders was identified, and enrollment was taken as the date of the first psychiatric diagnosis. Cases involved patients with a diagnosis of T2DM or prescriptions for glucose lowering drugs after enrollment, and the identification of T2DM was defined as the index date. We performed a conditional logistic regression analysis for matched case-control data to assess associations between AAP exposure and T2DM, and adjusted odds ratios (aORs) with 95% confidence intervals (CIs) are presented. From 1,092,019 patients aged 2-19 years, we identified 20,263 cases with T2DM and 80,043 controls, matched by sex, age, enrollment date, and primary psychiatric diagnosis. After adjusting for comorbidities, psychotropic medication history, and the healthcare institution characteristics, the aOR of having T2DM was significantly higher in multi-AAP users compared with non-users (aOR 1.89; 95% CI 1.63-2.20). Particularly high ORs for T2DM were observed in clozapine users compared with non-users (aOR 3.47; 95% CI 1.88-6.41). We observed a linear relationship between the increase in risperidone dose and the increase in the risk of developing T2DM. Our findings suggest a significantly increased risk of developing T2DM in child or adolescent patients with psychiatric disorders exposed to AAPs compared with those not exposed to AAPs. PMID- 29460166 TI - Common and distinct changes of default mode and salience network in schizophrenia and major depression. AB - Brain imaging reveals schizophrenia as a disorder of macroscopic brain networks. In particular, default mode and salience network (DMN, SN) show highly consistent alterations in both interacting brain activity and underlying brain structure. However, the same networks are also altered in major depression. This overlap in network alterations induces the question whether DMN and SN changes are different across both disorders, potentially indicating distinct underlying pathophysiological mechanisms. To address this question, we acquired T1-weighted, diffusion-weighted, and resting-state functional MRI in patients with schizophrenia, patients with major depression, and healthy controls. We measured regional gray matter volume, inter-regional structural and intrinsic functional connectivity of DMN and SN, and compared these measures across groups by generalized Wilcoxon rank tests, while controlling for symptoms and medication. When comparing patients with controls, we found in each patient group SN volume loss, impaired DMN structural connectivity, and aberrant DMN and SN functional connectivity. When comparing patient groups, SN gray matter volume loss and DMN structural connectivity reduction did not differ between groups, but in schizophrenic patients, functional hyperconnectivity between DMN and SN was less in comparison to depressed patients. Results provide evidence for distinct functional hyperconnectivity between DMN and SN in schizophrenia and major depression, while structural changes in DMN and SN were similar. Distinct hyperconnectivity suggests different pathophysiological mechanism underlying aberrant DMN-SN interactions in schizophrenia and depression. PMID- 29460167 TI - Alzheimer disease detection from structural MR images using FCM based weighted probabilistic neural network. AB - An early intervention of Alzheimer's disease (AD) is highly essential due to the fact that this neuro degenerative disease generates major life-threatening issues, especially memory loss among patients in society. Moreover, categorizing NC (Normal Control), MCI (Mild Cognitive Impairment) and AD early in course allows the patients to experience benefits from new treatments. Therefore, it is important to construct a reliable classification technique to discriminate the patients with or without AD from the bio medical imaging modality. Hence, we developed a novel FCM based Weighted Probabilistic Neural Network (FWPNN) classification algorithm and analyzed the brain images related to structural MRI modality for better discrimination of class labels. Initially our proposed framework begins with brain image normalization stage. In this stage, ROI regions related to Hippo-Campus (HC) and Posterior Cingulate Cortex (PCC) from the brain images are extracted using Automated Anatomical Labeling (AAL) method. Subsequently, nineteen highly relevant AD related features are selected through Multiple-criterion feature selection method. At last, our novel FWPNN classification algorithm is imposed to remove suspicious samples from the training data with an end goal to enhance the classification performance. This newly developed classification algorithm combines both the goodness of supervised and unsupervised learning techniques. The experimental validation is carried out with the ADNI subset and then to the Bordex-3 city dataset. Our proposed classification approach achieves an accuracy of about 98.63%, 95.4%, 96.4% in terms of classification with AD vs NC, MCI vs NC and AD vs MCI. The experimental results suggest that the removal of noisy samples from the training data can enhance the decision generation process of the expert systems. PMID- 29460165 TI - Efficacy and safety of drugs for attention deficit hyperactivity disorder in children and adolescents: a network meta-analysis. AB - The aim of this study is to gather evidence of head-to-head double-blind randomized-controlled trials on the efficacy and safety of available treatments for attention deficit hyperactivity disorder (ADHD) in children and adolescents. A systematic review was conducted by two independent reviewers in ten electronic databases (PROSPERO register CRD42016043239). Methodological quality of included studies was evaluated according to the Jadad scale. Network meta-analyses were performed including double-blinded head-to-head trials comparing active allopathic drugs in patients (0-18 years old) diagnosed with ADHD. The results of efficacy and safety of atomoxetine (ATX), bupropion, buspirone (BSP), dexamphetamine, edivoxetine (EDX), guanfacine (GXR), lisdexamfetamine (LDX), methylphenidate (MPH), mixed amphetamine salts, modafinil, pindolol (PDL), reboxetine (RBX), selegiline, and venlafaxine were analyzed using ADDIS software v.1.16.5. Forty-eight trials were identified (n = 4169 participants), of which 12 were used for efficacy analysis and 33 for safety analysis. On the CGI-I scale, the analysis revealed that MPH was more effective than ATX and GXR. For the safety outcomes, according to drug ranks, LDX was more likely to cause sleep disorders (39%) as well as loss of appetite (65%) and behavior problems such as irritability (60%). BSP (71%) and EDX (44%) caused less appetite decrease. For behavioral effects, PDL was considered safest (50%). For any adverse events, RBX (89%) was the safest alternative. The lack of head-to-head trials properly reporting outcomes of interest limited some comparisons. Network meta-analysis offered a broader overview on the available treatments for ADHD, especially for safety issues, and contributes towards evidence gathering and clinical practice decisions. A core outcome set for ADHD should be designed to guide the conduction and report of clinical trials. PMID- 29460168 TI - Multimethodology applied to the evaluation of Healthcare in Brazilian municipalities. AB - The integration of quantitative indicators with qualitative descriptions of context is a noticeable demand from many different scientific disciplines, since it contributes to linking theoretical and practical approaches to problem solving. Amongst them are the problem structuring methods, systems thinking and multimethodology. This work presents a mixed quantitative and qualitative methodological approach to aid formulation and structuring of performance measurement of health care in 5565 Brazilian municipalities. Data mining and data envelopment analysis (DEA) are applied in the context of conceptual mapping, thus shedding light on both quantitative and qualitative factors that influence health performance. Our aim is to propose a methodology for performance indicators to support health care policy making in Brazil, using quantitative indicators. However, the approach does not lose track of the role of important qualitative factors in the attribution of meaning to performance assessments. The methodological and analytical results can strengthen mutual understanding by analysts and stakeholders of the problem at hand. Quantitative results allow inefficient municipalities to understand the causes of their overall efficiency in terms of particular low partial DEA efficiencies combined with high deathrates. PMID- 29460169 TI - Spatial and Temporal Characteristics of Set-Related Inhibitory and Excitatory Inputs from the Dorsal Premotor Cortex to the Ipsilateral Motor Cortex Assessed by Dual-Coil Transcranial Magnetic Stimulation. AB - The capacity to produce movements only at appropriate times is fundamental in successful behavior and requires a fine interplay between motor inhibition and facilitation. Evidence in humans indicates that the dorsal premotor cortex (PMCd) is involved in such preparatory and inhibitory processes, but how PMCd modulates motor output in humans is still unclear. We investigated this issue in healthy human volunteers, using a variant of the dual-coil transcranial magnetic stimulation (TMS) technique that allows testing the short-latency effects of conditioning TMS to the left PMCd on test TMS applied to the ipsilateral orofacial primary motor cortex (M1). Participants performed a delayed cued simple reaction time task. They were asked to produce a lip movement cued by an imperative GO-signal presented after a predictable SET-period, during which TMS was applied at different intervals. Results showed that the area of motor evoked potentials (MEPs) to test TMS was modulated by conditioning TMS. A transient inhibition cortico-bulbar excitability by PMCd stimulation was observed around the middle of the SET-period. Conversely, a ramping excitatory effect of PMCd stimulation appeared towards the end of the SET-period, as the time of the predicted GO-signal approached. The time-course of PMCd-M1 activity scaled to the varying SET-period duration. Our data indicate that inhibition and excitation of motor output during a delayed reaction time task are two distinct neural phenomena. They both originate in PMCd and are conveyed via cortico-cortical connections to the ipsilateral M1, where they are integrated to produce harmonic fluctuations of motor output. PMID- 29460170 TI - [Epidemiology and diagnostic assessment of small renal masses]. AB - BACKGROUND: The incidence of small renal masses has been rising over the last few decades. At the same time, mortality of renal cell carcinoma (RCC) is decreasing. These trends can be explained by the availability of improved therapeutic measures and the good prognosis of small renal masses (SRM) turning out to be histopathologically benign or of low malignancy in many cases. OBJECTIVES: The aim of this article is to present epidemiology and diagnostic assessment of SRM. MATERIALS AND METHODS: Statistics, basic research, guidelines. RESULTS: The incidence of SRM is rising due to the widespread use of imaging techniques such as computed tomography (CT), magnetic resonance imaging (MRI), and contrast enhanced ultrasound (CEUS). Sensitivity is excellent for CEUS and for CECT in the characterization of SRM, while good specificity values can be reached by MRI. For characterization of complex cystic renal masses, CEUS has good diagnostic accuracy. CONCLUSIONS: Due to improved diagnostic possibilities, SRMs can be diagnosed in early asymptomatic stages. As SRM have a good prognosis and often are of low malignancy therapy, options should be carefully considered; especially in older patients, active surveillance should considered.

AB - Transformation is a memorable feature of some of the most iconic works of science fiction. These works feature characters who begin as humans and change into radically different kinds of being. This paper examines transformative change in the context of the Invasion of the Body Snatchers movies. I discuss how humans should approach the prospect of being body snatched. I argue that we shouldn't welcome the transformation even if we are convinced that we will have very positive experiences as pod aliens. When considering a transformative change, it is appropriate to give priority to your pre-transformation attitudes to potential future experiences and achievements over your predicted post-transformation attitudes. PMID- 29460173 TI - Changes in the axo-glial junctions of the optic nerves of cuprizone-treated mice. AB - Demyelination induced by cuprizone in mice has served a useful model system for the study of demyelinating diseases, such as multiple sclerosis. Severity of demyelination by cuprizone, however, varies across different regions of the central nervous system; the corpus callosum is sensitive, while the optic nerves are resistant. Here, we investigated the effects of cuprizone on optic nerves, focusing on the axo-glial junctions. Immunostaining for sodium channels, contactin-associated protein, neurofascins, and potassium channels revealed that there were no massive changes in the density and morphology of the axo-glial junctions in cuprizone-treated optic nerves. However, when we counted the number of incomplete junctional complexes, we observed increased numbers of isolated paranodes. These isolated paranodes were immunopositive for both axonal and glial membrane proteins, indicating that they were the contact sites between axons and glia. These were not associated with sodium channels or potassium channels, suggesting the absence of physiological functions. When teased axons from cuprizone-treated optic nerves were immunostained, the isolated paranodes were found at the internode region of the myelin. From these observations, we conclude that cuprizone induces new contacts between axons and myelins at the internode region. PMID- 29460174 TI - Management of closed sternal incision after bilateral internal thoracic artery grafting with a single-use negative pressure system. AB - Single-use, closed incision management (CIM) systems offer a practical means of delivering negative pressure wound therapy to patients. This prospective study evaluates the PrevenaTM Therapy system in a cohort of coronary patients at high risk of deep sternal wound infection (DSWI). Fifty-three consecutive patients undergoing bilateral internal thoracic artery (BITA) grafting were preoperatively elected for CIM with the PrevenaTM Therapy system, which was applied immediately after surgery. The actual rate of DSWI in these patients was compared with the expected risk of DSWI according to two scoring systems specifically created to predict either DSWI after BITA grafting (Gatti score) or major infections after cardiac surgery (Fowler score). The actual rate of DSWI was lower than the expected risk of DSWI by the Gatti score (3.8 vs. 5.8%, p = 0.047) but higher than by the Fowler score (2.3%, p = 0.069). However, while the Gatti score showed very good calibration (chi2 = 4.8, p = 0.69) and discriminatory power (area under the receiver-operating characteristic curve 0.838), the Fowler score showed discrete calibration (chi2 = 10.5, p = 0.23) and low discriminatory power (area under the receiver-operating characteristic curve 0.608). Single-use CIM systems appear to be useful to reduce the risk of DSWI after BITA grafting. More studies have to be performed to make stronger this finding. PMID- 29460176 TI - Marrow Fat-a New Target to Treat Bone Diseases? AB - PURPOSE OF REVIEW: The goal of this review is to summarize recent findings on marrow adipose tissue (MAT) function and to discuss the possibility of targeting MAT for therapeutic purposes. RECENT FINDINGS: MAT is characterized with high heterogeneity which may suggest both that marrow adipocytes originate from multiple different progenitors and/or their phenotype is determined by skeletal location and environmental cues. Close relationship to osteoblasts and heterogeneity suggests that MAT consists of cells representing spectrum of phenotypes ranging from lipid-filled adipocytes to pre-osteoblasts. We propose a term of adiposteoblast for describing phenotypic spectrum of MAT. Manipulating with MAT activity in diseases where impairment in energy metabolism correlates with bone functional deficit, such as aging and diabetes, may be beneficial for both. Paracrine activities of MAT might be considered for treatment of bone diseases. MAT has unrecognized potential, either beneficial or detrimental, to regulate bone homeostasis in physiological and pathological conditions. More research is required to harness this potential for therapeutic purposes. PMID- 29460175 TI - Preclinical and Translational Studies in Small Ruminants (Sheep and Goat) as Models for Osteoporosis Research. AB - PURPOSE OF THE REVIEW: This review summarizes research on the use of sheep and goats as large animal models of human osteoporosis for preclinical and translational studies. RECENT FINDINGS: The most frequent osteoporotic sheep model used is the ovariectomized sheep with 12 months post-operatively or more and the combined treatment of ovariectomized sheep associated to calcium/vitamin D-deficient diet and glucocorticoid applications for 6 months, but other methods are also described, like pinealectomy or hypothalamic-pituitary disconnection in ovariectomized sheep. The goat model for osteoporosis research has been used in a very limited number of studies in osteoporosis research relative to sheep. These osteoporotic small ruminant models are applied for biomaterial research, bone augmentation, efficacy of implant fixation, fragility fracture-healing process improvement, or bone-defect repair studies in the osteopenic or osteoporotic bone. Sheep are a recognized large animal model for preclinical and translational studies in osteoporosis research and the goat to a lesser extent. Recently, the pathophysiological mechanism underlying induction of osteoporosis in glucocorticoid-treated ovariectomized aged sheep was clarified, being similar to what occurs in postmenopausal women with glucocorticoid-induced osteoporosis. It was also concluded that the receptor activator of NF-kappaB ligand was stimulated in the late progressive phase of the osteoporosis induced by steroids in sheep. The knowledge of the pathophysiological mechanisms at the cellular and molecular levels of the induction of osteoporosis in small ruminants, if identical to humans, will allow in the future, the use of these animal models with greater confidence in the preclinical and translational studies for osteoporosis research. PMID- 29460177 TI - Simple diverticulectomy is adequate for management of bleeding Meckel diverticulum. AB - PURPOSE: It is unclear whether simple diverticulectomy, rather than segmental bowel resection (SBR), is adequate treatment for gastrointestinal bleeding (GIB) secondary to Meckel diverticulum (MD). There is concern that ulcers in the adjacent bowel may continue to bleed if only the diverticulum is removed. This study seeks to determine if diverticulectomy is satisfactory treatment for bleeding MD. METHODS: A multi-institution, retrospective review was performed for patients with a diagnosis of MD and GIB who underwent simple diverticulectomy or small bowel resection. Exclusion criteria were comorbid surgical conditions and other causes of GIB. The primary outcome was post-operative bleeding during the initial hospitalization. Secondary outcomes were bleeding after discharge, transfusion or additional procedure requirement, re-admission, and overall complications. RESULTS: There were 59 patients who met study criteria (42 diverticulectomy, 17 SBR). One patient in the SBR group had early post-operative bleeding (p = 0.288). There was one re-admission (p = 0.288) and three total complications in the SBR group (p = 0.021). There were no cases of bleeding or other complications in the diverticulectomy group. CONCLUSION: This study suggests that simple diverticulectomy is adequate for treatment of GIB caused by MD. Furthermore, diverticulectomy appears to have a lower overall complication rate. PMID- 29460178 TI - A cooperation of catheters and guidewires-based novel remote-controlled vascular interventional robot. AB - Remote-controlled vascular interventional robots (RVIRs) are being developed to increase the overall accuracy of surgical operations and reduce the occupational risks of intervening physicians, such as radiation exposure and chronic neck/back pain. Several RVIRs have been used to operate catheters or guidewires accurately. However, a lack of cooperation between the catheters and guidewires results in the surgeon being unable to complete complex surgery by propelling the catheter/guidewire to the target position. Furthermore, it is a significant challenge to operate the catheter/guidewire accurately and detect their proximal force without damaging their surfaces. In this study, we introduce a novel method that allows catheters and guidewires to be operated simultaneously in complex surgery. Our method accurately captures force measurements and enables precisely controlled catheter and guidewire operation. A prototype is validated through various experiments. The results demonstrate the feasibility of the proposed RVIR to operate a catheter and guidewire accurately, detect the resistance forces, and complete complex surgical operations in a cooperative manner. PMID- 29460179 TI - A siphonous morphology affects light-harvesting modulation in the intertidal green macroalga Bryopsis corticulans (Ulvophyceae). AB - MAIN CONCLUSION: The macroalga Bryopsis corticulans relies on a sustained protective NPQ and a peculiar body architecture to efficiently adapt to the extreme light changes of intertidal shores. During low tides, intertidal algae experience prolonged high light stress. Efficient dissipation of excess light energy, measured as non-photochemical quenching (NPQ) of chlorophyll fluorescence, is therefore required to avoid photodamage. Light-harvesting regulation was studied in the intertidal macroalga Bryopsis corticulans, during high light and air exposure. Photosynthetic capacity and NPQ kinetics were assessed in different filament layers of the algal tufts and in intact chloroplasts to unravel the nature of NPQ in this siphonous green alga. We found that the morphology and pigment composition of the B. corticulans body provides functional segregation between surface sunlit filaments (protective state) and those that are underneath and undergo severe light attenuation (light-harvesting state). In the surface filaments, very high and sustained NPQ gradually formed. NPQ induction was triggered by the formation of transthylakoid proton gradient and independent of the xanthophyll cycle. PsbS and LHCSR proteins seem not to be active in the NPQ mechanism activated by this alga. Our results show that B. corticulans endures excess light energy pressure through a sustained protective NPQ, not related to photodamage, as revealed by the unusually quick restoration of photosystem II (PSII) function in the dark. This might suggest either the occurrence of transient PSII photoinactivation or a fast rate of PSII repair cycle. PMID- 29460180 TI - Solidification of hydatid cyst fluid with an injectable chitosan/carboxymethylcellulose/beta-glycerophosphate hydrogel for effective control of spillage during aspiration of hydatid cysts. AB - Cystic echinococcosis (CE)/hydatid cyst is one of the most important helminthic diseases in the world. The treatment of hydatid cyst ranges from surgical intervention to chemotherapy, although the efficacy of chemotherapy is still unclear. Postoperative complication which results from the spillage of cysts during surgical operation is one of the most important concerns in surgical treatment of hydatid cyst. The aim of the current study was to solidify the hydatid cyst fluid (HCF) with an injectable and thermosensitive chitosan (CS)/carboxymethyl cellulose (CMC)/beta-glycerol phosphate (BGP) hydrogel for effective control of spillage during the aspiration of hydatid cysts. Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), water uptake, rheological analysis, and Alamar Blue cytotoxicity assay were employed to characterize the hydrogel. A five level with three times replication at the central point using a central composite design (CCD), which is a response surface methodology (RSM), was used to optimize the experimental conditions. Assessment of the produced hydrogel showed that the intermolecular interactions of amino groups of chitosan and hydrogen groups of CMC were correctively established and appreciable swelling with a good strength was obtained. Hydrogels morphology had a porous structure. Rheological analysis showed that CS/CMC/BGP blends had a phase transition (32-35 degrees C) of sol-gel close to the body temperature. Alamar Blue cytotoxicity assay showed that CS (1.75%)/CMC (1.4%)/BGP (2.9%) had IC50 values of 0.598, 0.235 and 0.138 (ug/uL) for 24, 48 and 72 h, which indicated that the produced polymer solution had no significant cytotoxic effect for human fibroblast cell line. In vitro injection of the polymer solution of CS/CMC/BGP with CS/CMC ratio of 1.75/1.4 was done on HCF (1 mL polymer solution to 3 mL of HCF) at 37 degrees C with a final concentration of 2.9% for BGP resulting in solidification of HCF in less than 45 min. PMID- 29460181 TI - Immunoisolation of stem cells by simultaneous encapsulation and PEGylation. AB - Today, cell therapy is known as an important tool in the treatment of chronic diseases where cells lose their normal function. Immunoisolation systems using microencapsulation or PEGylation have been developed to evade the problem of rejection by the immune system. The aim of the present study was to investigate a combination of microencapsulation and PEGylation methods in coating mouse embryonic stem cells (mESCs) to determine its effect in reducing the host's immune response. Therefore, methoxy polyethylene glycol (mPEG) binding on alginate-trimethyl chitosan (TMC) microcapsules was investigated using FTIR. Furthermore, survival of the microencapsulated mESCs was confirmed using AO/PI staining and MTT assays. In addition, the effect of mESCs co-cultured with foreign lymphocytes was evaluated. Overall, interleukin-2 (IL-2) secretions as a response of the immune system revealed that mESCs microencapsulation in alginate TMC-PEG, reduced the immune system response. The results suggested that IL-2 secretion was reduced to 62% at seventh day. PMID- 29460182 TI - The Time Point-Specific Effect of Beta-Adrenergic Blockade in Attenuating High Fat Diet-Induced Obesity and Bone Loss. AB - We aimed to clarify the key factor determining the effect of beta blocker attenuating high fat diet- induced obesity and bone loss. Six-week-old C57BL/6 male mice were assigned to groups reflecting different relative onset of obesity and beta blocker administration, different diet (control vs. high fat), and treatment (vehicle vs. beta blocker: propranolol). Mice in Group 1 were fed a control diet (CON) or high fat diet (HIGH) with vehicle or propranolol for 12 weeks. Mice in Group 2 were fed a CON or HIGH without pharmaceutical treatment for the first 12 weeks, followed by another 12 weeks of treatment with vehicle or propranolol. Mice in Group 3 were fed a CON without pharmaceutical treatment for the first 12 weeks, followed by stratification into diet-based subgroups and another 12 weeks of treatment with vehicle or propranolol. Propranolol attenuated the HIGH-induced increase in body weight/fat mass in Group 1 mice and in Group 3 mice, but not in Group 2 mice. Propranolol mitigated HIGH-induced reduction in femoral trabecular bone mineral density and bone architecture deterioration in Group 1 mice but not in Group 2 mice. HIGH feeding in Group 3 did not compromise skeletal integrity. Taken together, propranolol attenuates HIGH-induced body weight increases while weight gain is in progress but not once obesity has already been established. HIGH feeding during the growth period results in compromised bone mass/architecture; which can be attenuated by propranolol administration during the growth period, but not by propranolol administration after obesity has already been established. PMID- 29460183 TI - Nutritional history does not modulate hepatic oxidative status of European sea bass (Dicentrarchus labrax) submitted to handling stress. AB - The aim of the present study was to assess the impact of an acute handling stress on hepatic oxidative status of European sea bass (Dicentrarchus labrax) juveniles fed diets differing in lipid so urce and carbohydrate content. For that purpose, four diets were formulated with fish oil (FO) and vegetable oils (VO) as lipid source and with 20 or 0% gelatinized starch as carbohydrate source. Triplicate groups of fish with 74 g were fed each diet during 13 weeks and then subjected to an acute handling stress. Stress exposure decreased hematocrit (Ht) and hemoglobin (Hb) levels. Independent of dietary treatment, stress exposure increased hepatic lipid peroxidation (LPO). Stressed fish exhibited lower glucose 6-phosphate dehydrogenase (G6PD), catalase (CAT), and superoxide dismutase (SOD) activities, independent of previous nutritional history. In the VO groups, stress exposure increased glutathione peroxidase (GPX) activity. Diet composition had no effect on Ht and Hb levels. In contrast, dietary carbohydrate decreased hepatic LPO and CAT activity and increased glutathione reductase (GR) and G6PD activities. Dietary lipids had no effect on LPO. Fish fed the VO diets exhibited higher G6PD activity than fish fed the FO diets. In conclusion, dietary carbohydrates contributed to the reduction of oxidative stress in fish. However, under the imposed handling stress conditions, liver enzymatic antioxidant mechanisms were not enhanced, which may explain the overall increased oxidative stress.

AB - White Spot Syndrome Virus (WSSV), the etiological agent of White Spot Disease (WSD) is a major impediment for shrimp aquaculture in the worldwide. A critical threshold level of WSSV load in infected shrimp is an important trait for disease manifestation and WSSV transmission in cultured shrimp and subsequently make outbreaks. The present study investigated 120 naturally infected cultured shrimp samples by SYBR Green based qPCR assay for WSD diagnosis and quantification of WSSV load. Among them, 94 samples resulted a variable count of WSSV load ranging from 2.1 * 108 to 2.64 * 1014 copies/g of shrimp tissue. The severity of WSSV infection was assessed based on the established critical threshold load of WSSV in shrimp tissue. Compared to the established critical threshold value of WSSV load in shrimp tissue, our findings showed the horrifying scenario of the severity of WSSV infection in cultured shrimps of Bangladesh that was found to be above the critical limit to initiate an outbreak in the Bangladeshi shrimp aquaculture industry. The latest phylogenetic pattern was altered from the former monophyletic history among WSSVs of Bangladesh due to a variation at 500th nucleotide of VP28 coding gene. Viruses characterized from recent outbreaks in 2015 and 2017 displayed amino acid substitution at position 167 (G->E) on the surface of VP28 protein which has demonstrated the probable replacement of indigenous virus pool. Therefore, it is imperative to take initiative for the management and prevention of WSSV outbreak to sustain shrimp aquaculture in South West region of Bangladesh.

AB - Key environmental factors and the mechanisms of their influence on the physicochemical habitats and macroinvertebrate communities of streams may vary among ecoregions. We studied the differences in environmental (land use and physicochemical) factors and the mechanisms of their influence on macroinvertebrate assemblages between mountain and lowland ecoregions in central China. We applied generalized linear models to identify key environmental factors that influence macroinvertebrate metrics consisting of taxa richness, Ephemeroptera, Plecoptera, and Trichoptera (EPT) taxa, percentages of EPT and intolerant individuals, and the Shannon-Wiener diversity index. Environmental factors and macroinvertebrate metrics significantly differed between the ecoregions. Mountain streams had significantly lower nutrients and %silt, but had twice higher total taxa richness than lowland streams. Watershed land uses were key drivers that influenced the physical habitat in the mountain ecoregion and were the main drivers that influenced both physical and chemical conditions in the lowland ecoregion. Correspondingly, watershed scale land uses, as well as physical and chemical variables, explained more variance in macroinvertebrate metrics than local-scale land uses in both mountain and lowland ecoregions. The overall biological variation was explained better by watershed-scale than by reach-scale land uses, whereas the spatial scale over which land use and physicochemical variables influence streams varied across ecoregions. Our results suggest that better landscape planning should be adopted for watershed management to improve water quality and physical habitat, and thus the conservation and restoration of macroinvertebrate biodiversity.

AB - Subcritical co-solvents of n-hexane/isopropanol were primarily utilized to extract lipid from wet microalgal pastes of Scenedesmus obliquus. The effects of key operational parameters were investigated, and the optimal parameters were obtained: solvent ratio of n-hexane to isopropanol was 3:2 (V:V), phase ratio of co-solvents to microalgal biomass was 35:1 (mL:g), reactor stirring speed was 900 rpm, extraction time was 60 min. Additional pretreatment with acid, ultrasonic and microwave as well as enhanced subcritical pressure/heating treatments were also applied to further study their effects on lipid extraction. The results showed that the lipid recovery rate with acid pretreatment was 8.6 and 6.2% higher than ultrasonic and microwave pretreatment; the optimum enhanced subcritical condition was 55 degrees C with atmospheric pressure. Under optimal operating conditions, the lipid and FAME yield were 13.5 and 7.2%, which was 82.6 and 135.1% higher than the traditional method. The results indicated that the subcritical n-hexane/isopropanol extraction process had promising application potential. PMID- 29460188 TI - Motivational Factors in Women Seeking Augmentation Mammoplasty Across Different Age Groups: A Cross-Sectional Survey. AB - BACKGROUND: Augmentation mammoplasty is one of the most common esthetic procedures worldwide. A wide range of motivations leads women to undergo this procedure, among them socioeconomic status and age group. The aim of this study was to identify the motivation spectrum for augmentation mammoplasty through different age groups. METHODS: We conducted a cross-sectional prospective survey given to Israeli women seeking augmentation mammoplasty consults in a hospital and private clinic settings, using a 17-item Motivation for Augmentation questionnaire. Three motivation domains were examined: appearance, sexuality and social. Study participants were divided into three age groups: 18-29, 30-39 and over 40 years. RESULTS: A total of 101 women participated in the study. Motivations were rated similar among all age groups. Appearance and sexuality domains were rated significantly higher compared with the social domain throughout all age groups (3.28 +/- 0.91 and 3.15 +/- 1.03 vs. 1.88 +/- 1.16, p < 0.001, respectively). CONCLUSIONS: Motivations in Israeli women seeking breast augmentation do not change with age. The desire to improve one's appearance and sexuality is more prominent than improving social and work status.

PMID- 29460189 TI - Response to Time-Out Among Preschoolers with Externalizing Behavior Problems: The Role of Callous-Unemotional Traits. AB - This study examined the role of callous-unemotional (CU) traits in preschoolers with externalizing behavior problems (EBP) and their response to time-out (TO). One hundred ninety preschoolers (76% boys, Mage = 4.92) with at-risk/clinically elevated levels of EBP participated in an 8-week summer treatment program (STP PreK). Total number of minutes spent daily in TO for intentional aggression (IA) and repeated non-compliance (RNC) were recorded during the initial (T1) and final (T2) phases of the STP-PreK. After accounting for severity of EBP and levels of TO at T1, higher levels of CU traits predicted greater total levels of TO at T2. An interaction also emerged between symptoms of oppositional defiant disorder (ODD) and CU traits in predicting IA. Specifically, greater ODD symptoms predicted fewer number of IA related TO at T2, but only for children with low CU traits. Implications for treatment are discussed. PMID- 29460190 TI - Quantitative analysis of phantom studies of 111In and 68Ga imaging of neuroendocrine tumours. AB - BACKGROUND: Nuclear medicine imaging of neuroendocrine tumours is performed either by SPECT/CT imaging, using 111In-octreotide or by PET/CT imaging using 68Ga-radiolabelled somatostatin analogs. These imaging techniques will give different image quality and different detection thresholds for tumours, depending on size and activity uptake. The aim was to evaluate the image quality for 111In SPECT and 68Ga-PET imaging, i.e. the smallest volume possible to visualize for different source-to-background activity ratios. The accuracy of quantification of lesion volume and activity was also investigated to develop an objective evaluation for radionuclide therapy eligibility. The phantom study was performed using the NEMA IEC Body Phantom with six hot spheres having inner diameters of 10, 13, 17, 22, 28, and 37 mm, filled with either 68Ga or 111In with sphere-to background ratios (SBRs) of no background activity, 5:1, 2.5:1, and 1.25:1. Activity ratios of 1.25:1 and 2.5:1 are clinically found for lesions close to the liver and spleen. Clinical acquisition and reconstruction protocols were applied. Line profiles were drawn to evaluate the smallest detectable volume within a given SBR. Recovery curves based on threshold-based VOIs, threshold-based VOIs adapted to the background and CT-based ROIs were obtained for all SBRs and sphere diameters, allowing for quantification. RESULTS: The 10-mm sphere was not possible to detect in SPECT images. It was detectable in PET images for SBRs of 2.5:1 and higher. In a background corresponding to the activity uptake in the liver, spheres larger than 22-37 mm were detectable in the 111In-SPECT images and spheres larger than 13-22 mm were detectable in the 68Ga-PET images. The maximum activity concentration was accurately quantified for spheres larger than 22 mm in the PET images; however, the quantification was impaired by sphere size and background activity. CONCLUSIONS: It was not possible to detect the 10-mm sphere in any of the SPECT images. In a background corresponding to the activity uptake in the liver, spheres larger than approximately 30 mm were visible in the 111In SPECT images and spheres larger than approximately 17 mm were visible in the 68Ga PET images. Sphere diameter and background activity strongly affect the possibility of a correct quantification. PMID- 29460191 TI - Multivariate analysis and health risk assessment of heavy metal contents in foodstuffs of Durban, South Africa. AB - This study presented a comprehensive analysis of heavy metal contents in foodstuffs and the associated health risk for the residential population in Durban, South Africa. The concentrations of elements in fruits and vegetables, respectively, were (in mg kg-1 dry weight) Cu, 0.52-1.47 and 0.27-2.25; Zn, 0.30 3.05 and 0.56-6.24, Fe, 1.70-22.60 and 0.73-44.90; Mn, 0.37-28.50 and 0.67-13.70; Cr, 0.47-1.47 and 0.37-3.06; Ni 0.03-1.14 and 0.11-2.5;, and Pb, 1.52-3.45 and 1.57-4.52. Multivariate analysis revealed that pineapple in fruits and turnip and carrot in vegetables contained remarkable components of trace metals. The target hazard quotient (THQ) values for heavy metals were arranged in the order of Pb > Mn > Cu > Ni > Zn > Cr. No potential health risks were reported for individual elements over a lifetime of exposure, except children's exposure to Mn in pineapple and Pb in banana, orange small, guava, grape green, grape red, yellow orange, and kiwifruit. The total THQ due to the dietary intake of multiple metals demonstrated unsafe limits in banana, pineapple, orange small, guava, grape green, grape red, yellow-orange, kiwifruit, and spinach leaf for children and pineapple for adults. PMID- 29460192 TI - Aberrant Expression of Some Circulating miRNAs in Childhood Acute Lymphoblastic Leukemia. AB - Acute lymphoblastic leukemia (ALL) is a heterogeneous cancer commonly affecting children due to dysregulation of miRNA expression. In the current study, authors investigated the expression profile for miRNA-125b-1 and miRNA-203 among childhood ALL. Blood samples were collected from newly diagnosed childhood ALL and healthy control children. The expression profile for candidate miRNAs was detected using quantitative RT-PCR analysis. Statistical analysis were performed using receiver operating characteristic curve (ROC) to examine the diagnostic efficacy of the two miRNA and their levels among ALL clinicopathological factors and phenotypes. The median expression level for miRNA-125b-1 was significantly high in childhood ALL; while miRNA-203 level was significantly low in childhood ALL as compared to control ones. MiRNA-125-1 reported significant increase in T ALL as compared to other ALL phenotypes. Median miRNA-203 level was high in T-ALL followed by pre-B-ALL although no significant difference was reported. Clinicopathological factors did not emphasize significance with either detected miRNAs. Using ROC curve the diagnostic efficacy was significant with an area under the curve 0.858 for miRNA-125b-1 (83.72, 100%) and 0.878 for miRNA-203 (97.67, 86.96%). The combination of the two key miRNAs revealed absolute sensitivity (100%). MiRNA-125b-1 and miRNA-203 can be useful molecular markers for diagnosis of ALL. Further studies with large cohort are warranted to validate these results. PMID- 29460193 TI - Use of compression garments by women with lymphoedema secondary to breast cancer treatment. AB - PURPOSE: This aim of this study was to determine the use of compression garments by women with lymphoedema secondary to breast cancer treatment and factors which underpin use. METHODS: An online survey was distributed to the Survey and Review group of the Breast Cancer Network Australia. The survey included questions related to the participants' demographics, breast cancer and lymphoedema medical history, prescription and use of compression garments and their beliefs about compression and lymphoedema. Data were analysed using principal component analysis and multivariable logistic regression. RESULTS: Compression garments had been prescribed to 83% of 201 women with lymphoedema within the last 5 years, although 37 women had discontinued their use. Even when accounting for severity of swelling, type of garment(s) and advice given for use varied across participants. Use of compression garments was driven by women's beliefs that they were vulnerable to progression of their disease and that compression would prevent its worsening. Common reasons given as to why women had discontinued their use included discomfort, and their lymphoedema was stable. Participant characteristics associated with discontinuance of compression garments included their belief that (i) the garments were not effective in managing their condition, (ii) experienced mild-moderate swelling and/or (iii) had experienced swelling for greater than 5 years. CONCLUSION: The prescription of compression garments for lymphoedema is highly varied and may be due to lack of underpinning evidence to inform treatment. PMID- 29460194 TI - Spiritual well-being associated with personality traits and quality of life in family caregivers of cancer patients. AB - PURPOSE: This study focuses on the spiritual well-being (SWB) of the family caregivers of cancer patients, examining the relationship with personality traits and quality of life (QoL) in palliative and curative care settings. METHODS: All participants (n = 199) underwent the following self-report questionnaires: the Structural Analysis of Social Behavior (SASB)-Form A, the SWB Index, and the Medical Outcomes Study Short Form (SF-36). SWB scores were dichotomized at a cutoff corresponding to the 75th percentile. STATISTICAL ANALYSIS: Student's t test or by chi squared tests to compare high and low SWB and multivariate linear regression to estimate relations between SWB, SASB clusters (Cl), and QoL dimensions. RESULTS: Caregivers with high SWB reported significantly better scores than low SWB caregivers in the following SF-36 subscales: bodily pain (p = 0.035), vitality (p < 0.001), social activities (p < 0.001), mental health subscales (p < 0.001), and standardized mental component (p < 0.001) in the SASB Cl2 (p < 0.005), SASB Cl7 (p = 0.007), and SASB Cl8 (p < 0.001). Multivariate linear regression was performed with vitality, standardized mental component, SASB Cl2, SASB Cl7, and SASB Cl8. Greater SWB is associated with greater vitality (p < 0.001), mental standardized component (p < 0.001), and SASB Cl2 (p < 0.001), but lower SASB Cl7 (p < 0.05) and SASB Cl8 (p < 0.05); palliative care is associated with greater SASB Cl8 (p < 0.05) and lower standardized mental component compared with the caregivers in active care. CONCLUSIONS: This study points out that caregivers who experience low SWB have a poorer QoL and more problematic intrapsychic aspects of personality, such as low self-acceptance of their own emotions, are self-refusing and unable to be in contact with their own feelings. This suggests that spirituality could be a source of strength and a potential avenue for therapeutic intervention. PMID- 29460195 TI - High risk for obstructive sleep apnea hypopnea syndrome predicts new onset atrial fibrillation after cardiac surgery: a retrospective analysis. AB - PURPOSE: Obstructive sleep apnea hypopnea syndrome (OSAHS) is highly prevalent in patients undergoing coronary artery bypass surgery (CABG). OSAHS is a risk factor for the development of atrial fibrillation (AF), but the risk of AF in patients who are high risk for OSAHS is unclear. METHODS: A retrospective study was conducted on consecutive patients undergoing CABG from 2013 to 2015 without AF pre-operatively. Patients were categorized as low risk for OSAHS, high risk for OSAHS, or diagnosed OSAHS based on medical records review. All diagnosed OSAHS patients were on active treatment with positive airway pressure. Outcomes assessed were postoperative AF (POAF), postoperative length of stay, re intubation, in-hospital mortality, and cost of hospitalization. RESULTS: Out of 209 eligible patients, 66.5% were low-risk for OSAHS, 18.7% high-risk for OSAHS, and 14.8% diagnosed/treated for OSAHS. POAF developed in 96 patients (45.9%) with greater frequency in high-risk OSAHS patients (69.2% high risk, 41.9% low risk, 40.3% diagnosed/treated, p = 0.01). In analyses adjusted for age, sex, ethnicity and comorbidities, high risk for OSAHS was associated with 2.9 greater odds (95% CI [1.2, 7.3], p = 0.02) for POAF while diagnosed/treated OSAHS was not associated with elevated risk (OR = 1.4, 95% CI [0.6, 3.6], p = 0.50) compared to patients at low risk for OSAHS. CONCLUSIONS: High risk for OSAHS is an independent predictor for POAF in patients undergoing CABG. In contrast, patients diagnosed and treated for their OSAHS are not at elevated risk of POAF. These findings support evaluation of a standardized OSAHS screening and treatment program as part of the pre-operative evaluation for elective CABG. PMID- 29460196 TI - A comparative study of biotechnological approaches for producing valuable flavonoids in Prosopis farcta. AB - The callus and hairy root cultures of Prosopis farcta were established to develop effective strategies to enhance its valuable and medicinally important flavonoid compounds. For callus induction, the hypocotyl, cotyledon and shoot explants were subjected to different plant hormones, naphthalene acetic acid (NAA), benzylaminopurine (BAP), kinetin and dichlorophenoxyacetic acid (2,4-D). Greater callus induction was obtained from hypocotyl explants on MS medium containing 3.0 mg L-1 NAA + 2.0 mg L-1 BAP. With the addition of 0.5 mg L-1 asparagine to this medium, the maximum callus growth was achieved. Hairy root culture of P. farcta was performed using transformation of different explants with strains of Agrobacterium rhizogenes LBA9404, A4, AR15834. The AR15834 strain was more effective for hairy root induction where it caused hairy root formation on 59% of the infected cotyledon explants. We compared profiles of flavonoids isolated from seedling roots, hairy roots, and callus cultures of P. farcta. The colorimetric analysis showed that the content of total flavonoids of hairy roots was 1.54 and 2.52 times higher than in seedling roots and callus, respectively. The presence of flavonoids was verified by LC/MS in positive ion mode. The results showed that flavonoid composition was different in the roots and callus. Naringenin was the major constituent in callus, whereas resveratrol, quercetin and myricetin were the most abundant compounds found in hairy roots. The main objective of this research was to establish hairy roots in P. farcta to synthesize flavonoids at levels comparable to in vitro-grown roots. The present study also opens up a way to further improve the production of pharmaceutically valuable flavonoids and to produce desired metabolites using the hairy root culture system. PMID- 29460197 TI - Anti inflammatory effect of asiaticoside on human umbilical vein endothelial cells induced by ox-LDL. AB - Early diagnosis and changes associated with atherosclerosis are crucial in clinical medicine. However, atherosclerosis is a multifactorial disease. Asiaticoside (AA), a triterpenoid derived from Centella asiatica, has anti inflammatory activity. Endothelium-derived nitric oxide is important in modulating vascular tone in a distinct vessel size-dependent manner; it plays a dominant role in conduit arteries and endothelium-dependent hyperpolarisation in resistance vessels. This study evaluated the effects of AA administration on human umbilical endothelial cells with oxidised low-density lipoprotein-induced inflammation. We measured the levels of intercellular adhesion molecule-1 (ICAM 1) and vascular cell adhesion molecule-1 (VCAM-1). Our results indicated that 10 30 MUM AA modulated endothelial hyper permeability, adenosine triphosphate levels, ICAM-1 expression, VCAM-1 expression, E-selectin levels, and PECAM-1 expression to 90% (p < 0.005), 80% (p < 0.05), 105% (p < 0.01), 65% (p < 0.005), 70% (p < 0.05), and 105% (p < 0.01), respectively. Taken together, our data suggest that AA inhibits the augmentation of endothelial permeability, thus preventing the early events of atherosclerosis. PMID- 29460198 TI - Collaborative environmental DNA sampling from petal surfaces of flowering cherry Cerasus * yedoensis 'Somei-yoshino' across the Japanese archipelago. AB - Recent studies have shown that environmental DNA is found almost everywhere. Flower petal surfaces are an attractive tissue to use for investigation of the dispersal of environmental DNA in nature as they are isolated from the external environment until the bud opens and only then can the petal surface accumulate environmental DNA. Here, we performed a crowdsourced experiment, the "Ohanami Project", to obtain environmental DNA samples from petal surfaces of Cerasus * yedoensis 'Somei-yoshino' across the Japanese archipelago during spring 2015. C. * yedoensis is the most popular garden cherry species in Japan and clones of this cultivar bloom simultaneously every spring. Data collection spanned almost every prefecture and totaled 577 DNA samples from 149 collaborators. Preliminary amplicon-sequencing analysis showed the rapid attachment of environmental DNA onto the petal surfaces. Notably, we found DNA of other common plant species in samples obtained from a wide distribution; this DNA likely originated from the pollen of the Japanese cedar. Our analysis supports our belief that petal surfaces after blossoming are a promising target to reveal the dynamics of environmental DNA in nature. The success of our experiment also shows that crowdsourced environmental DNA analyses have considerable value in ecological studies. PMID- 29460199 TI - Delayed selfing ensures reproductive assurance in Utricularia praeterita and Utricularia babui in Western Ghats. AB - Numerous bladderwort (Utricularia) species are distributed worldwide, but their reproductive biology is rarely investigated. Bladderworts are known to depend on tiny organisms to meet a significant proportion of their energy requirement by trapping them in bladders. However, information on the extent of their reliance on insects for pollination success is limited. We examined the reproductive strategy of two Utricularia species viz. Utricularia praeterita and U. babui, endemic to Western Ghats, India. The main aspects of the investigation involved floral biology, breeding system, pollination mechanism, and reproductive success. Flowers of both the species are structured for outbreeding through entomophilous floral suites, herkogamy, protandrous dichogamy and sensitive lobes of the stigma. With nearly 65% natural fruit-set, both the species appeared to be sufficiently open-pollinated. However, pollinators failed to show in plants of U. praeterita while in U. babui there was an apparent mismatch between the extent of fruit-set and pollinator visits. The study demonstrated that in the absence/insufficient visits of pollinators, the two species resort to autonomous selfing. In U. babui, denser patches of plants appeared to be crucial for attracting the pollinators. Both species are self-compatible, and reproductive success is predominantly achieved by delayed autonomous selfing. The sensitive stigma in the species fails to prevent selfing due to diminished herkogamy during the late anthetic stages. It is inferred that in the pollinator-limited environment, delayed selfing contributes to absolute natural fecundity in U. praeterita, while it produces a mixed progeny in U. babui. PMID- 29460200 TI - A novel high-sensitivity assay to detect a small fraction of mutant IDH1 using droplet digital PCR. AB - Detection of mutations in the isocitrate dehydrogenase 1 (IDH1) gene is useful for accurate diagnosis of lower grade gliomas, as described in the 2016 World Health Organization classification of tumors of the central nervous system. Conventional analysis tools, including Sanger DNA sequencing and immunohistochemistry, might fail to detect a small fraction of mutant IDH1 owing to their limited sensitivity. Considering that lower grade gliomas are infiltrative in nature, a highly sensitive detection assay for IDH1 mutation is required for their accurate diagnosis. In this study, we successfully established a droplet digital PCR (ddPCR) system to detect a small fraction of IDH1 mutation. We could detect 0.05% of mutant IDH1 allele in 30 ng DNA. Using this assay, we could detect a small fraction of mutant IDH1 in a glioma case, identified as a wildtype tumor according to the conventional assays. Additionally, in a small amount of DNA derived from the cerebrospinal fluid, we could detect an IDH1 mutation. In conclusion, the ddPCR system is useful to identify a small fraction of IDH1 mutation in diffuse infiltrative gliomas. This might be useful for precision medicine of these gliomas in the near future and also for the non invasive diagnosis of these gliomas. PMID- 29460201 TI - Patients with refractory ascites treated with alfapump(r) system have better health-related quality of life as compared to those treated with large volume paracentesis: the results of a multicenter randomized controlled study. AB - BACKGROUND: Refractory ascites (RA) is a complication of cirrhosis which is treated with large volume paracentesis (LVP) as the standard of care. Alfapump(r) system is a fully implantable pump system which reduces the need for LVP. The aim was to assess health-related quality of life (HRQL) in patients treated with alfapump(r) versus LVP. METHODS: The data were collected in a multicenter open label randomized controlled trial (clinicaltrials.gov #NCT01528410). Subjects with cirrhosis Child-Pugh class B or C accompanied by RA were randomized to receive alfapump(r) or LVP. The SF-36v2 and CLDQ scores were compared between the two treatment arms at screening and monthly during treatment. RESULTS: Of 60 subjects randomized, HRQL data were available for 58 (N = 27 received alfapump(r) and N = 31 received LVP only). At baseline, no differences were seen between the treatment arms (all p > 0.05): age 61.9 +/- 8.4, 79.3% male, MELD scores 11.7 +/- 3.3, 85.2% Child-Pugh class B, 70.7% had alcoholic cirrhosis. The mean number of LVP events/subject was lower in alfapump(r) than LVP (1.1 vs. 8.6, p < 0.001). The HRQL scores showed a moderate improvement from the baseline levels in subjects treated with alfapump(r) (p < 0.05 for abdominal and activity scores of CLDQ) but not with LVP (all one-sided p > 0.05) in the first 3 months. Multivariate analysis showed that treatment with alfapump(r) was independently associated with better HRQL at 3 months (total CLDQ score: beta = 0.67 +/- 0.33, p = 0.05). CONCLUSION: As compared to LVP, the use of alfapump(r) system is associated with both a reduction in the number of LVP events and improvement of health-related quality of life. PMID- 29460203 TI - Time Is Cerebellum. AB - The cerebellum characteristically has the capacity to compensate for and restore lost functions. These compensatory/restorative properties are explained by an abundant synaptic plasticity and the convergence of multimodal central and peripheral signals. In addition, extra-cerebellar structures contribute also to the recovery after a cerebellar injury. Clinically, some patients show remarkable improvement of severe ataxic symptoms associated with trauma, stroke, metabolism, or immune-mediated cerebellar ataxia (IMCA, e.g., multiple sclerosis, paraneoplastic cerebellar degeneration, gluten ataxia, anti-GAD65 antibody associated cerebellar ataxia). However, extension of a cerebellar lesion can impact upon the fourth ventricle or the brainstem, either by direct or indirect mechanisms, leading to serious complications. Moreover, cerebellar reserve itself is affected by advanced cell loss and, at some point of disease progression, deficits become irreversible. Such phase transition from a treatable/restorable state (the reserve is still sufficient) to an untreatable state (the reserve is severely affected) is a loss of therapeutic opportunity, highlighting the need for early treatment during the restorable stage. Based on the motto of "Time is Brain," a warning that stresses the importance of early therapeutic intervention in ischemic diseases, we propose "Time is Cerebellum" as a principle in the management of patients with cerebellar diseases, especially immune ataxias whose complexity often delay the therapeutic intervention. Indeed, this concept should not be restricted to ischemic cerebellar diseases. We argue that every effort should be made to reduce the diagnostic delay and to initiate early therapy to avoid the risk of transition from a treatable state to an irreversible condition and an associated accumulation of disability. The myriad of disorders affecting the cerebellum is a challenging factor that may contribute to irreversible disability if the window of therapeutic opportunity is missed. PMID- 29460202 TI - Clinicopathological significance of baseline T2-weighted signal intensity in functional pituitary adenomas. AB - PURPOSE: To assess baseline T2-weighted signal intensity (T2-WSI) of functional pituitary adenomas (FPA), and to investigate the relationship of baseline T2-WSI with clinical features, histopathological granulation patterns, and response to treatment in patients with acromegaly, prolactinoma and Cushing's disease (CD). METHODS: Somatotroph adenomas (n = 87), prolactinomas (n = 78) and corticotroph adenomas (n = 29) were included in the study. Baseline T2-WSI findings (grouped as hypo-, iso- and hyperintense) were compared with hormone levels, tumor diameter, granulation patterns and response to treatment. RESULTS: Somatotroph adenomas were mostly hypointense (53%), prolactinomas were dominantly hyperintense (55%), and corticotroph adenomas were generally hyperintense (45%). Hyperintense somatotroph adenomas were larger in size with sparsely granulated pattern and tumor shrinkage rate was lower after somatostatin analogues (SSA) (p = 0.007, p = 0.035, p = 0.029, respectively). T2 hypointensity was related with higher baseline IGF-1% ULN (upper limit of normal) levels and a better response to SSA treatment (p = 0.02, p = 0.045, respectively). In female prolactinomas, hyperintensity was correlated with a smaller adenoma diameter (p = 0.001). Hypointense female prolactinomas were related to younger age at diagnosis, higher baseline PRL levels and dopamine agonist (DA) resistance (p = 0.009, p = 0.022, p < 0.001, respectively). Hyperintense corticotroph adenomas were related to larger adenoma size and sparsely granulated pattern (p = 0.04, p = 0.017, respectively). There was no significant difference in the recurrence with T2WSI in CD. CONCLUSION: Baseline hypointense somatotroph adenomas show a better response to SSA, whereas hypointensity was related to DA resistance in female prolactinomas. PMID- 29460204 TI - Development of a Psychiatric Disorder Linked to Cerebellar Lesions. AB - Cerebellar dysfunction plays a critical role in neurodevelopmental disorders with long-term behavioral and neuropsychiatric symptoms. A 43-year-old woman with a cerebellum arteriovenous malformation and history of behavioral dysregulation since childhood is described. After the rupture of the cerebellar malformation in adulthood, her behavior morphed into specific psychiatric symptoms and cognitive deficits occurred. The neuropsychological assessment evidenced impaired performance in attention, visuospatial, memory, and language domains. Moreover, psychiatric assessment indicated a borderline personality disorder. Brain MRI examination detected macroscopic abnormalities in the cerebellar posterior lobules VI, VIIa (Crus I), and IX, and in the posterior area of the vermis, regions usually involved in cognitive and emotional processing. The described patient suffered from cognitive and behavioral symptoms that are part of the cerebellar cognitive affective syndrome. This case supports the hypothesis of a cerebellar role in personality disorders emphasizing the importance of also examining the cerebellum in the presence of behavioral disturbances in children and adults. PMID- 29460205 TI - Phylogeny and bioactivity of epiphytic Gram-positive bacteria isolated from three co-occurring antarctic macroalgae. AB - Marine macroalgae are emerging as an untapped source of novel microbial diversity and, therefore, of new bioactive secondary metabolites. This study was aimed at assessing the diversity and antimicrobial activity of the culturable Gram positive bacteria associated with the surface of three co-occurring Antarctic macroalgae. Specimens of Adenocystis utricularis (brown alga), Iridaea cordata (red alga) and Monostroma hariotii (green alga) were collected from the intertidal zone of King George Island, Antarctica. Gram-positive bacteria were investigated by cultivation-based methods and 16S rRNA gene sequencing, and screened for antimicrobial activity against a panel of pathogenic microorganisms. Isolates were found to belong to 12 families, with a dominance of Microbacteriaceae and Micrococcaceae. Seventeen genera of Actinobacteria and 2 of Firmicutes were cultured from the three macroalgae, containing 29 phylotypes. Three phylotypes within Actinobacteria were regarded as potentially novel species. Sixteen isolates belonging to the genera Agrococcus, Arthrobacter, Micrococcus, Pseudarthrobacter, Pseudonocardia, Sanguibacter, Staphylococcus, Streptomyces and Tessaracoccus exhibited antibiotic activity against at least one of the indicator strains. The bacterial phylotype composition was distinct among the three macroalgae species, suggesting that these macroalgae host species specific Gram-positive associates. The results highlight the importance of Antarctic macroalgae as a rich source of Gram-positive bacterial diversity and potentially novel species, and a reservoir of bacteria producing biologically active compounds with pharmacological potential. PMID- 29460206 TI - Deciphering the trophic interaction between Akkermansia muciniphila and the butyrogenic gut commensal Anaerostipes caccae using a metatranscriptomic approach. AB - Host glycans are paramount in regulating the symbiotic relationship between humans and their gut bacteria. The constant flux of host-secreted mucin at the mucosal layer creates a steady niche for bacterial colonization. Mucin degradation by keystone species subsequently shapes the microbial community. This study investigated the transcriptional response during mucin-driven trophic interaction between the specialised mucin-degrader Akkermansia muciniphila and a butyrogenic gut commensal Anaerostipes caccae. A. muciniphila monocultures and co cultures with non-mucolytic A. caccae from the Lachnospiraceae family were grown anaerobically in minimal media supplemented with mucin. We analysed for growth, metabolites (HPLC analysis), microbial composition (quantitative reverse transcription PCR), and transcriptional response (RNA-seq). Mucin degradation by A. muciniphila supported the growth of A. caccae and concomitant butyrate production predominantly via the acetyl-CoA pathway. Differential expression analysis (DESeq 2) showed the presence of A. caccae induced changes in the A. muciniphila transcriptional response with increased expression of mucin degradation genes and reduced expression of ribosomal genes. Two putative operons that encode for uncharacterised proteins and an efflux system, and several two component systems were also differentially regulated. This indicated A. muciniphila changed its transcriptional regulation in response to A. caccae. This study provides insight to understand the mucin-driven microbial ecology using metatranscriptomics. Our findings show that the expression of mucolytic enzymes by A. muciniphila increases upon the presence of a community member. This could indicate its role as a keystone species that supports the microbial community in the mucosal environment by increasing the availability of mucin sugars. PMID- 29460208 TI - A statistical approach to explore cemented total hip reconstruction performance. AB - This study was carried out to determine mechanical behavior and bone adaptation of total hip arthroplasty (THA) subject to concentrated and distributed muscle loads and hip contact forces during activities of walking and stair climbing. Finite element modeling of THA with different prostheses, activity and loading types was developed by adopting a statistical method. Two levels of prostheses, activity, and loading types were selected for the study. 23 factorial method was then pursued to design input and output data of finite element analysis. Maximum von Mises stresses were chosen to be output data on which statistical investigation was performed to investigate contribution and interaction of main factors on mechanical failure of cemented THA reconstructions by utilizing analysis of variance method (ANOVA). This study illustrated that the maximum von Mises stresses of THA showed considerable variation for main factors and their two-factor interactions. PMID- 29460207 TI - Bird feathers as potential sources of pathogenic microorganisms: a new look at old diseases. AB - This article describes methods of treatment for avian zoonoses, modern antibiotic therapy and drug resistance of selected pathogens, which pose a threat to the population's health. A tabular form has been used to present the current data from the European Union from 2011 to 2017 regarding human morbidity and mortality and the costs incurred by national health systems for the treatment of zoonoses occurring in humans and animals. Moreover, the paper includes descriptions of selected diseases, which indirectly affect birds. Scientists can obtain information regarding the occurrence of particular diseases, their aetiology, epidemiology, incubation period and symptoms caused by dangerous microorganisms and parasites. This information should be of particular interest for people who have frequent contact with birds, such as ornithologists, as well as veterinarians, farm staff, owners of accompanying animals and zoological workers. This paper presents a review used for identification and genetic characterization of bacterial strains isolated from a variety of environmental sources, e.g., bird feathers along with their practical application. We describe the bacterial, viral and fungal serotypes present on avian feathers after the slaughter process. This review also enables us to effectively identify several of the early stages of infectious diseases from heterogeneous avian research material. PMID- 29460209 TI - PCA-based selection of distinctive stability criteria and classification of post stroke pathological postural behaviour. AB - In this paper, we study the postural behaviour of two categories of people: Post CVA subjects suffering from cerebrovascular accident syndromes and healthy individuals under several levels of anterior-posterior and medial-lateral sinusoidal disturbances (0.1-0.5 Hz). These perturbations were produced from an omnidirectional platform called Isiskate. Afterwards, we have quantified seventy postural parameters, they were combined of linear stabilometric parameters and non-linear time dependent stochastic parameters using stabilogram diffusion analysis and some spectral attributes using power spectral density. The aim of our analysis is to reduce data dimensionality using principal component analysis (PCA). Furthermore, we proposed a new PCA-related criterion named: criterion of contribution in order to evaluate the contribution of every variable in the resulted system structure, and thus to eliminate the redundant postural characteristics. Afterwards, we highlighted some interesting distinctive parameters. The selected parameters were used thereafter in comparison between the studied groups. Finally, we created a classification model using support vector machines to distinguish stroke patients. Our proposed techniques help in understanding the human postural dynamics and facilitate the diagnosis of pathologies related to equilibrium which can be used to improve the rehabilitation services.

PMID- 29460211 TI - Validation of a Social Networks and Support Measurement Tool for Use in International Aging Research: The International Mobility in Aging Study. AB - The purpose of this study was to develop and validate a new instrument to assess social networks and social support (IMIAS-SNSS) for different types of social ties in an international sample of older adults. The study sample included n = 1995 community dwelling older people aged between 65 and 74 years from the baseline of the longitudinal International Mobility in Aging Study (IMIAS). In order to measure social networks for each type of social tie, participants were asked about the number of contacts, the number of contacts they see at least once a month or have a very good relationship with, or speak with at least once a month. For social support, participants had to rate the level of social support provided by the four types of contacts for five Likert scale items. Confirmatory Factor Analysis was conducted to determine the goodness of fit of the measurement models. Satisfactory goodness-of-fit indices confirmed the satisfactory factorial structure of the IMIAS-SNSS instrument. Reliability coefficients were 0.80, 0.81, 0.85, and 0.88 for friends, children, family, and partner models, respectively. The models were confirmed by CFA for each type of social tie. Moreover, IMIAS SNSS detected gender differences in the older adult populations of IMIAS. These results provide evidence supporting that IMIAS-SNSS is a psychometrically sound instrument and of its validity and reliability for international populations of older adults. PMID- 29460212 TI - Involvement of NF-kappaB in mediating the anti-tumour effects of combretastatins in T cells. AB - Purpose The combretastatins (CAs) are known to exhibit anti-tumour activity but the underlying mechanism remains to be fully elucidated. Inflammation plays a critical role in altering the function of cancer cells and evasion of cell death and increased proliferation are characteristics of transformed malignancies. Many of the proteins involved in these pathways are regulated by the transcription factor NF-kappaB which can be activated by tumour necrosis factor (TNF-alpha), a pro-inflammatory cytokine released by both malignant and immune cells within the tumour microenvironment. In this study, we examined the ability of combretastatin A-4 (CA-4) and its novel, cis-restricted analogue CA-432 to target the NF-kappaB signalling pathway in T cells. Methods Effects of the CAs on the viability of DND 41 leukaemia and Jurkat lymphoma T-cell lines was assessed by the alamar blue assay. Induction of apoptosis and effects on expression levels of key apoptotic proteins was established though flow cytometry and western blotting. Modulation of the NF-kappaB signalling pathway was determined through western blotting and through assessment of NF-kappaB reporter gene activity. Results CA-4 and CA-432 reduced cell viability and induced apoptosis in DND-41 and Jurkat T cells and sensitised the cells to TNF-alpha-induced apoptosis through inhibition of the NF kappaB signalling pathway. Suppression of the NF-kappaB pathway downregulated NF kappaB-dependent gene products involved in cell survival (IAPs, Bcl-2 and Mcl-1), proliferation (cyclin D1) and inflammation (COX-2). Furthermore, both CA-4 and CA 432 inhibited TNF-alpha-induced NF-kappaB activation through the inhibition of IkappaBalpha degradation and p65 nuclear translocation and decreased NF-kappaB reporter gene activity. Conclusions Our data indicate that the anti-cancer properties of comebretastatins may be mediated in part through targeting the NF kappaB pathway. This study provides new insights into the molecular mechanisms of CA compounds and a potential application of combretastatins for inflammatory diseases such as cancers, which are associated with abnormal NF-kappaB activation. PMID- 29460213 TI - Evaluating the Probiotic Potential of Lactobacillus plantarum Strains from Algerian Infant Feces: Towards the Design of Probiotic Starter Cultures Tailored for Developing Countries. AB - Lactobacilli naturally present in the neonatal gut are believed to be beneficial for the human hosts and are investigated as potential probiotics. In this study, we aimed to characterize six Lactobacillus plantarum strains derived from the feces of a breast-fed infant, for the development of new probiotic cultures. Our attention was focused on L. plantarum in reason of the presence, within such species, of both pro-technological and probiotic strains, i.e., a combination of particular interest to design tailored probiotic starter cultures for developing countries. The bacterial isolates exhibiting lactobacilli-like phenotypic characteristics were identified as members of the L. plantarum group by 16S rRNA gene sequencing, and their diversity was evaluated by randomly amplified polymorphic DNA (RAPD) PCR patterns. The selected strains were screened for probiotic potential through in vitro tests. Firstly, bacterial survival was evaluated in an in vitro system simulating the human oro-gastrointestinal tract, using also milk as a carrier matrix. Besides, physiological traits such as antibiotic susceptibility, antimicrobial activity against selected enteric pathogens, and adhesion to abiotic surfaces and to gastric mucin were studied. Considering the resistance to simulated gastrointestinal digestion and the results from the biofilm and mucin adhesion tests, a strain-denominated L. plantarum LSC3 was selected for further evaluation of in vitro adhesion ability to intestinal mucosa and immunomodulatory activities. L. plantarum LSC3 was able to adhere efficiently to human enterocyte-like cells (Caco-2 cells), and decreased IL-8 transcription while increasing IL-10 mRNA level, as revealed by transcriptional analysis on LPS-stimulated human (THP-1) macrophages. Our results highlight that L. plantarum LSC3 fulfills major in vitro probiotic criteria as well as interesting immunostimulatory properties, and thus may be a promising candidate for further in vivo studies aiming at the development of novel probiotic starter cultures. PMID- 29460214 TI - Rational design and analysis of an Escherichia coli strain for high-efficiency tryptophan production. AB - L-tryptophan (L-trp) is a precursor of various bioactive components and has great pharmaceutical interest. However, due to the requirement of several precursors and complex regulation of the pathways involved, the development of an efficient L-trp production strain is challenging. In this study, Escherichia coli (E. coli) strain KW001 was designed to overexpress the L-trp operator sequences (trpEDCBA) and 3-deoxy-D-arabinoheptulosonate-7-phosphate synthase (aroG fbr ). To further improve the production of L-trp, pyruvate kinase (pykF) and the phosphotransferase system HPr (ptsH) were deleted after inactivation of repression (trpR) and attenuation (attenuator) to produce strain KW006. To overcome the relatively slow growth and to increase the transport rate of glucose, strain KW018 was generated by combinatorial regulation of glucokinase (galP) and galactose permease (glk) expression. To reduce the production of acetic acid, strain KW023 was created by repressive regulation of phosphate acetyltransferase (pta) expression. In conclusion, strain KW023 efficiently produced 39.7 g/L of L-trp with a conversion rate of 16.7% and a productivity of 1.6 g/L/h in a 5 L fed-batch fermentation system. PMID- 29460215 TI - Potential of biogenic methane for pilot-scale fermentation ex situ with lump anthracite and the changes of methanogenic consortia. AB - Pilot-scale fermentation is one of the important processes for achieving industrialization of biogenic coalbed methane (CBM), although the mechanism of biogenic CBM remains unknown. In this study, 16 samples of formation water from CBM production wells were collected and enriched for methane production, and the methane content was between 3.1 and 21.4%. The formation water of maximum methane production was used as inoculum source for pilot-scale fermentation. The maximum methane yield of the pilot-scale fermentation with lump anthracite amendment reached 13.66 MUmol CH4/mL, suggesting that indigenous microorganisms from formation water degraded coal to produce methane. Illumina high-throughput sequencing analysis revealed that the bacterial and archaeal communities in the formation water sample differed greatly from the methanogic water enrichment culture. The hydrogenotrophic methanogen Methanocalculus dominated the formation water. Acetoclastic methanogens, from the order Methanosarcinales, dominated coal bioconversion. Thus, the biogenic methanogenic pathway ex situ cannot be simply identified according to methanogenic archaea in the original inoculum. Importantly, this study was the first time to successfully simulate methanogenesis in large-capacity fermentors (160 L) with lump anthracite amendment, and the result was also a realistic case for methane generation in pilot-scale ex situ. PMID- 29460216 TI - Methodological Considerations in Couples' Fertility Intentions: Missing Men and the Viability of Women's Proxy Reports. AB - Introduction Recent efforts show potential to advance research on unintended childbearing by taking a couple-level approach. However, this work has neither adequately addressed methodological concerns stemming from the challenges associated with male fertility data nor considered the viability of women's proxy reports of fathers intentions. Methods Data from the Early Childhood Longitudinal Study, Birth Cohort (ECLS-B) were used to assess the implications of low response rates among men on couples' unintended childbearing. Then, the accuracy of women's proxy reports of fathers intentions was assessed. Weighted logistic regression analyses were conducted to determine how women's characteristics were associated with men's survey participation whereas weighted multinomial logistic regression analyses were applied to determine how women's characteristics were linked with the accuracy of her proxy report. Results Almost half (46%) of women cannot be matched with data from the child's father, and this discrepancy is most problematic for women who are black, foreign-born, less educated, and unmarried at birth. Women's proxy reports appear viable as 75% of women's reports are consistent with men's responses. Yet, proxy reports underestimate disagreement in couples' intentions as mothers who intended the birth are at an increased risk of "inaccurately" reporting that fathers share their intentions. Discussion Direct approaches to couples' intentions yield privileged samples and systematically omit women at the greatest risk of an unintended birth. However, proxies underestimate disagreement in couples' intentions-a key contribution to the couple approach. Accordingly each approach has its own merits which must be considered in light of specified research questions. PMID- 29460217 TI - Maternal Sociodemographic Characteristics, Experiences and Health Behaviors Associated with Postpartum Care Utilization: Evidence from Maryland PRAMS Dataset, 2012-2013. AB - Objectives Postpartum visits are increasingly recognized as a window of opportunity for health care providers to counsel new mothers and promote healthy behaviors, including increasing contraceptive use and screening for postpartum depression. In Maryland, there is a lack of research on postpartum visit (PPV) attendance and the specific risk factors associated with not receiving postpartum care. In this study, we estimated the proportion of mothers in Maryland who attended a PPV and assessed maternal sociodemographic characteristics and health behaviors associated with PPV non-attendance. Methods Data were analyzed from the 2012 and 2013 Maryland Pregnancy Risk Assessment Monitoring System (n = 2204). Bivariate and multivariable logistic regression were performed to examine the association between covariates and PPV non-attendance. Results Overall, 89.6% of women reported PPV attendance. Bivariate analyses between maternal sociodemographic and health behavior characteristics and PPV non-attendance indicated that being unmarried (OR 3.03, 95% CI 2.12-4.31), experiencing infant loss (OR 7.17, 95% CI 2.57-19.97), working during pregnancy (OR 0.44, 95% CI 0.31 0.63) and not receiving dental care (OR 2.03, 95% CI 1.43-2.88) as significant risk factors for PPV non-attendance. After controlling for known and theoretical confounders, experiencing an infant loss (aOR 5.18, 95% CI 1.54-17.4), not receiving dental care (aOR 1.54, 95% CI 1.06-2.26) and working during pregnancy (aOR 0.61, 95% CI 0.41-0.93) emerged as strong predictors of PPV non-attendance. Conclusions for Practice Mothers who recently experienced an infant death were at greatest risk for not attending a PPV, suggesting the need to establish comprehensive support networks, including grief counseling and additional service reminders for mothers who experienced an infant death. PMID- 29460218 TI - Hypoglycemia in type 2 diabetes: understanding patients' and physicians' knowledge and experience. AB - PURPOSE: The aim of the current study is to assess the patient and physician experience and knowledge of hypoglycemia in the management of type 2 diabetes (T2DM). METHODS: T2DM patients (N = 1002) completed questionnaires on hypoglycemia experience, familiarity, and fear. Their responses were compared across various antihyperglycemic treatment regimens; specifically, (1) insulin only or insulin combined with sulfonylurea [SU] and/or metformin, (2) SU only with/without metformin, and (3) neither insulin nor SU. Physicians (N = 1003) completed questionnaires on hypoglycemia knowledge and decision-making, and their responses were compared by specialty [75% primary care providers (PCPs) and 25% endocrinologists]. RESULTS: T2DM patients treated with, (1) insulin only, or (2) insulin plus SU or metformin, reported the most experience and familiarity with but also fear of-hypoglycemic events. Insulin-treated patients (insulin alone or insulin plus SU/metformin) also reported experiencing more hypoglycemia (all p values <0.012). For physicians, endocrinology specialty was significantly associated with higher hypoglycemia knowledge scores (all p-values <.001). Irrespective of specialty, physician hypoglycemia knowledge, in turn, was associated with correct treatment decision-making (all p-values <0.001). CONCLUSIONS: Insulin-based antihyperglycemic regimens were associated with high prevalence, severity, familiarity, and fear of hypoglycemia. An effective strategy to mitigate the burden of hypoglycemia may be to optimize pharmacological therapy to prevent these events. Since physician hypoglycemia knowledge was highly correlated to correct therapeutic decision-making, continued physician education regarding this acute complication of diabetes treatment should be prioritized for those managing patients with T2DM. PMID- 29460220 TI - Molecular identification of common Salmonella serovars using multiplex DNA sensor based suspension array. AB - Salmonella is one of major foodborne pathogens and the leading cause of foodborne illness-related hospitalizations and deaths. It is critical to develop a sensitive and rapid detection assay that can identify Salmonella to ensure food safety. In this study, a DNA sensor-based suspension array system of high multiplexing ability was developed to identify eight Salmonella serovars commonly associated with foodborne outbreaks to the serotype level. Each DNA sensor was prepared by activating pre-encoded microspheres with oligonucleotide probes that are targeting virulence genes and serovar-specific regions. The mixture of 12 different types of DNA sensors were loaded into a 96-well microplate and used as a 12-plex DNA sensor array platform. DNA isolated from Salmonella was amplified by multiplex polymerase chain reaction (mPCR), and the presence of Salmonella was determined by reading fluorescent signals from hybridization between probes on DNA sensors and fluorescently labeled target DNA using the Bio-Plex(r) system. The developed multiplex array was able to detect synthetic DNA at the concentration as low as 100 fM and various Salmonella serovars as low as 100 CFU/mL within 1 h post-PCR. Sensitivity of this assay was further improved to 1 CFU/mL with 6-h enrichment. The array system also correctly and specifically identified serotype of tested Salmonella strains without any cross-reactivity with other common foodborne pathogens. Our results indicate the developed DNA sensor suspension array can be a rapid and reliable high-throughput method for simultaneous detection and molecular identification of common Salmonella serotypes. PMID- 29460221 TI - The genetics of aniridia - simple things become complicated. AB - Aniridia is a rare, panocular disorder characterized by a variable degree of hypoplasia or the absence of iris tissue associated with additional ocular abnormalities. It is inherited in an autosomal dominant manner, with high penetrance and variable expression even within the same family. In most cases the disease is caused by haploinsufficiency truncating mutations in the PAX6 gene; however, in up to 30% of aniridia patients, disease results from chromosomal rearrangements at the 11p13 region. The aim of this review is to present the clinical and genetic aspects of the disease. Furthermore, we present a molecular diagnostic strategy in the aniridia patients. Recent improvement in the genetic diagnostic approach will precisely diagnosis aniridia patients, which is essential especially for children with aniridia in order to determine the risk of developing a Wilms tumor or neurodevelopmental disorder. Finally, based on the previous studies we describe the current knowledge and latest research findings in the topic of pathogenesis of aniridia and possible future treatment. PMID- 29460222 TI - Heavy Metal Exposure and Metabolic Syndrome: Evidence from Human and Model System Studies. AB - PURPOSE OF REVIEW: Metabolic syndrome (MS) describes the co-occurrence of conditions that increase one's risk for heart disease and other disorders such as diabetes and stroke. The worldwide increase in the prevalence of MS cannot be fully explained by lifestyle factors such as sedentary behavior and caloric intake alone. Environmental exposures, such as heavy metals, have been implicated, but results are conflicting and possible mechanisms remain unclear. To assess recent progress in determining a possible role between heavy metal exposure and MS, we reviewed epidemiological and model system data for cadmium (Cd), lead (Pb), and mercury (Hg) from the last decade. RECENT FINDINGS: Data from 36 epidemiological studies involving 17 unique countries/regions and 13 studies leveraging model systems are included in this review. Epidemiological and model system studies support a possible association between heavy metal exposure and MS or comorbid conditions; however, results remain conflicting. Epidemiological studies were predominantly cross-sectional and collectively, they highlight a global interest in this question and reveal evidence of differential susceptibility by sex and age to heavy metal exposures. In vivo studies in rats and mice and in vitro cell-based assays provide insights into potential mechanisms of action relevant to MS including altered regulation of lipid and glucose homeostasis, adipogenesis, and oxidative stress. Heavy metal exposure may contribute to MS or comorbid conditions; however, available data are conflicting. Causal inference remains challenging as epidemiological data are largely cross sectional; and variation in study design, including samples used for heavy metal measurements, age of subjects at which MS outcomes are measured; the scope and treatment of confounding factors; and the population demographics vary widely. Prospective studies, standardization or increased consistency across study designs and reporting, and consideration of molecular mechanisms informed by model system studies are needed to better assess potential causal links between heavy metal exposure and MS. PMID- 29460223 TI - PrEP Stigma: Implicit and Explicit Drivers of Disparity. AB - PURPOSE OF REVIEW: Despite its promise as an HIV prevention strategy, PrEP uptake remains slow, especially among highest priority populations. One factor that may be impeding implementation and driving disparities is PrEP-related stigma. This paper reviews the role of PrEP-related stigma in PrEP access, adherence, and persistence and examines its antecedents and consequences. RECENT FINDINGS: Although PrEP stigma is often experienced at the community level (i.e., by potential and current users), it can be reinforced and even amplified by public health programs, policy, and research. PrEP stigma disproportionately impacts disadvantaged groups and impedes scalability by influencing behavior of both patients and providers. Reducing PrEP stigma and its negative impact on the epidemic requires a significant shift in perspective, language, and programs. Such a shift is necessary to ensure broader reach of PrEP as a prevention strategy and improve its utilization by the individuals who need it most. PMID- 29460224 TI - Molecular Signatures of HIV-1 Envelope Associated with HIV-Associated Neurocognitive Disorders. AB - PURPOSE OF REVIEW: The HIV-1 envelope gene (env) has been an intense focus of investigation in the search for genetic determinants of viral entry and persistence in the central nervous system (CNS). RECENT FINDINGS: Molecular signatures of CNS-derived HIV-1 env reflect the immune characteristics and cellular constraints of the CNS compartment. Although more readily found in those with advanced HIV-1 and HIV-associated neurocognitive disorders (HAND), molecular signatures distinguishing CNS-derived quasispecies can be identified early in HIV 1 infection, in the presence or absence of combination antiretroviral therapy (cART), and are dynamic. Amino acid signatures of CNS-compartmentalization and HAND have been identified across populations. While some significant overlap exists, none are universal. Detailed analyses of CNS-derived HIV-1 env have allowed researchers to identify a number of molecular determinants associated with neuroadaptation. Future investigations using comprehensive cohorts and longitudinal databases have the greatest potential for the identification of robust, validated signatures of HAND in the cART era. PMID- 29460225 TI - The Syndemic of Opioid Misuse, Overdose, HCV, and HIV: Structural-Level Causes and Interventions. AB - PURPOSE OF REVIEW: This article reviews the case for recognizing (1) the epidemics of opioid misuse, overdose, hepatitis C virus, and HIV as a syndemic and (2) the importance of examining and addressing structural factors in responses to this syndemic. We focus on the current syndemic in the US, but also consider data from other locations to highlight the issues existing and arising in various contexts. RECENT FINDINGS: Advances in multi-level theory and statistical methods allow sound ecologic and multi-level analyses of the impact of structural factors on the syndemic. Studies of opioid misuse, overdoses, hepatitis C virus, and HIV demonstrate that area-level access to healthcare, medication-assisted treatment of opioid use disorders, sterile injection equipment, and overdose prevention with naloxone, as well as factors such as opioid marketing, income inequality, intensity of policing activities, and health care policies, are related to the prevalence of substance misuse, overdoses, infection risk, and morbidity. Structural variables can predict area-level vulnerability to the syndemic. The implementation of combined prevention and treatment interventions can control and reverse components of the syndemic. Recognizing and monitoring potent structural factors can facilitate the identification of areas at risk of vulnerability to the syndemic. Further, many structural factors are modifiable through intervention and policy to reduce structural vulnerability and create health-enabling environments. Evidence supports the immediate implementation of broader HCV and HIV testing and substance use screening, medication-assisted treatment, needle/syringe exchange programs, naloxone programs, increased population-level implementation of HCV treatment, and further attention to structural-level factors predicting, and contributing to, area-level vulnerability, such as degrees of opioid marketing, distribution, and prescribing. PMID- 29460226 TI - Genetic Cluster Analysis for HIV Prevention. AB - PURPOSE OF REVIEW: This review summarizes the use of genetic similarity clusters to understand HIV transmission and inform prevention efforts. RECENT FINDINGS: Recent emphases include the development of real-time cluster identification in order to interrupt transmission chains, the use of clusters to estimate rates of transmission along the HIV care cascade, and the extension of cluster analyses to understand transmission in the generalized epidemics of sub-Saharan Africa. Importantly, this recent empirical work has been accompanied by theoretical work that elucidates the processes that underlie HIV genetic similarity clusters; multiple studies suggest that clusters are not necessarily enriched with individuals with high transmission rates, but rather can reflect variation in sampling times within a population, with individuals sampled early in infection more likely to cluster. Analyses of genetic similarity clusters have great promise to inform HIV epidemiology and prevention. Future emphases should include the collection of additional sequence data from underrepresented populations, such as those in sub-Saharan Africa, and further development and evaluation of clustering methods. PMID- 29460227 TI - Do frequent exposures to threats and violence at work affect later workforce participation? AB - PURPOSE: Threats and violence at work are common problems in the human service sector. It can result in physical and psychological health symptoms. The aim of this study was to examine the association between exposure to threats and violence and workforce participation in four human service sectors. METHODS: 5170 employees answered questionnaires about threats and violence in 2010 and were followed in a register for public transfer incomes for 3.5 years to identify episodes of sick leave, general workforce participation, and permanent health related benefits. RESULTS: We found associations between exposures to threats and violence at work and workforce participation, though only a few specific types of threats and violence were associated on their own. Self-rated severity of both threatening and violent episodes was associated with overall low workforce participation, new sick leave episodes, and permanent health-related benefits. However, the latter was not statistically significant. The same pattern seems to be present in the relation between the total amount of exposure to threats and violence (threats score and violence score), respectively, and overall low workforce participation and new sick leave episodes. The threats score was also related to permanent health-related benefits. CONCLUSION: Exposure to threats and violence is associated with temporary and permanent health-related benefits as well as with low workforce participation in general, although some of the associations were not statistically significant. PMID- 29460228 TI - Prevalence of asymptomatic sexually transmitted infections in HIV-positive men who have sex with men in Germany: results of a multicentre cross-sectional study. AB - PURPOSE: Sexually transmitted infections (STIs) occur frequently in risk populations. Hereby, the role of screening-programmes remains controversial. Our study aimed to determine the prevalence of STI infections in HIV-positive men-who have-sex-with-men (MSM). METHODS: We enrolled asymptomatic, HIV-MSM in a prospective cross-sectional study from February to August 2016 at seven German HIV-centres. All subjects were screened for Treponema-pallidum (TP) and hepatitis B/C-infection. HIV RNA and screening for oral, rectal and urethral colonisation by Chlamydia-trachomatis (CT) and/or Neisseria-gonorrhoeae (NG) was performed. All subjects were asked to complete a sexual-risk-behaviour-questionnaire. RESULTS: In total, 296 subjects with a median age of 43.2 (36.2-49.5) years were enrolled; 99.3% were on ART for 5.5 (2.3-11.2) years. HIV RNA was < 50 copies/mL in 93.6%. Active syphilis infection was found in 5.0% of all patients, whereas 55.4% had history of infection. HCV seropositivity was found in 33 patients (13.2%) and positive HCV RNA was available in 39.4%. 66/294 (22.5%) showed negative anti-HBs-antibodies, indicating lack of immunity. Overall, 40/296 (13.5%) had positive CT/NG swabs (CT in 8.8%; 7.3% anorectal, 1.7% oropharyngeal, 1.0% urethral and NG in 6.8%; 4.5% anal, 2.0% oropharyngeal, 1.4% urethral). Time since HIV infection < 7 years (OR 2.6 (1.2-5.5); p = 0.012), the use of inhalative nitrites ("poppers") (OR 2.8 (1.3-5.9; p = 0.008) and reporting unprotected intercourse with > 20 partners within the last 6 months [OR 3.0 (1.2 7.8); p = 0.003] were significantly associated in multivariate analysis. CONCLUSION: We found high numbers of asymptomatic syphilis, hepatitis-C and CT/NG infections in HIV-MSM, remarkably in patients with shorter duration of HIV infection with more sexual partners within last 6 months.

AB - The cuff electrode provides a stable interface with peripheral nerves, which has been widely used in basic research and clinical practice. Currently, the cuff electrodes are limited by the planar processing of microfabrication. This paper presents a novel cuff electrode using high-aspect ratio carbon nanotubes (CNTs) integrated on a flexible biocompatible parylene. The microfabrication process unites the high quality vertical CNTs grown at high temperature with the heat sensitive parylene substrate in a highly controllable manner. The fabricated cuff electrodes have been utilized for extracellular nerve stimulation in rats. The experimental results demonstrate the proposed CNT electrode has a better performance than Pt electrode in nerve stimulation. Moreover, the effect of electrode position and stimulation frequency is demonstrated in this paper. This preliminary data indicates that flexible 3D CNTs cuff electrode provides an excellent platform for functional electrical stimulation.

AB - Multidrug-resistant (MDR) Pseudomonas aeruginosa infection causes significant mortality among patients with hematologic malignancies and hematopoietic-cell transplant recipients. Ceftolozane-tazobactam (C-T) is a novel therapeutic option for MDR-P. aeruginosa infections but clinical experience in these patients is limited. We report favorable clinical outcomes and lack of limiting toxicities using C-T monotherapy to treat invasive MDR-P. aeruginosa infections in these patient populations. PMID- 29460231 TI - A biocompatible sol-gel derived titania coating for medical implants with antibacterial modification by copper integration. AB - Implant-associated infections are dangerous complications and may cause dramatic illness with hematogeneous spread of bacteria and secondary infections. Since treatment of these infections remains most challenging and commonly requires implant removal, prevention is of utmost importance. In the present work a titania-sol was equipped with a copper salt resulting after calcination in a titania coating (TiO2) with antibacterial properties combined with good cytocompatibility. In vitro tests with bacteria as well as tissue cells were carried out under corresponding conditions. Mouse fibroblasts and different staphylococcal strains were used for growth inhibition assays with serial dilutions of CuCl2. Cultivation on the surface of bare Ti6Al4V, TiO2-coated and copper-filled TiO2-coated Ti6Al4V samples was performed with both bacteria and tissue cells. Bacterial and cellular proliferation and mitochondrial activity were hereby determined. Coating of Ti6Al4V with pure TiO2 significantly improved cytocompatibility compared to the uncoated alloy. In the growth inhibition assays, fibroblasts tolerated higher concentrations of copper ions than did bacteria. Nevertheless, copper integration reduced fibroblast proliferation and mitochondrial activity on the surface coating. On the other hand, integration of copper into the TiO2-coating significantly reduced adhesion of viable bacteria resulting in a promising combination of cytocompatibility and antibacterial properties. Additionally, significant bacterial growth inhibition by antibacterial amounts of copper was also demonstrated in the supernatant. In conclusion, the copper-loaded TiO2-coatings for medical implants may be a promising approach to reduce the rate of implant-associated infections. PMID- 29460232 TI - Atrial fibrillation ablation using very short duration 50 W ablations and contact force sensing catheters. AB - PURPOSE: The optimal radiofrequency (RF) power and lesion duration using contact force (CF) sensing catheters for atrial fibrillation (AF) ablation are unknown. We evaluate 50 W RF power for very short durations using CF sensing catheters during AF ablation. METHODS: We evaluated 51 patients with paroxysmal (n = 20) or persistent (n = 31) AF undergoing initial RF ablation. RESULTS: A total of 3961 50 W RF lesions were given (average 77.6 +/- 19.1/patient) for an average duration of only 11.2 +/- 3.7 s. As CF increased from < 10 to > 40 g, the RF application duration decreased from 13.7 +/- 4.4 to 8.6 +/- 2.5 s (p < 0.0005). Impedance drops occurred in all ablations, and for patients in sinus rhythm, there was loss of pacing capture during RF delivery suggesting lesion creation. Only 3% of the ablation lesions were at < 5 g and 1% at > 40 g of force. As CF increased, the force time integral (FTI) increased from 47 +/- 24 to 376 +/- 102 gs (p < 0.0005) and the lesion index (LSI) increased from 4.10 +/- 0.51 to 7.63 +/- 0.50 (p < 0.0005). Both procedure time (101 +/- 19.7 min) and total RF energy time (895 +/- 258 s) were very short. For paroxysmal AF, the single procedure freedom from AF was 86% at 1 and 2 years. For persistent AF, it was 83% at 1 year and 72% at 2 years. There were no complications. CONCLUSIONS: Short duration 50 W ablations using CF sensing catheters are safe and result in excellent long-term freedom from AF for both paroxysmal and persistent AF with short procedure times and small amounts of total RF energy delivery. PMID- 29460233 TI - Late cure of focal ventricular arrhythmias post-catheter ablation: electrophysiological characteristics and long-term outcome. AB - PURPOSE: Late cure after a previously failed ablation of ventricular arrhythmias (VAs) is a relatively common phenomenon. The present study sought to delineate the incidence and electrophysiological characteristics of late cure in idiopathic VA patients. METHODS: Totally, 45 idiopathic VA cases (mean age 44 +/- 18 years, 27 males) either failed acutely or recurred within 12 h were enrolled in this study. Based on intensive clinical observations in the acute period, 19 (42%) patients demonstrated late cure in the first week after the procedure. RESULTS: The late cure patients had significantly better acute and cumulative ablation effects during the procedure than did those without a late cure. Additionally, they had a prediction that originated from the right ventricular outflow tract, aortic-mitral continuum, and left summit area relative to other sites (13/18 vs 6/27, p < 0.01). In a median follow-up of 24 [14, 46] months, 7/19 (37%) patients had their VAs recurred. The late cure group had significantly more patients cured at long-term follow-up than those without (12/19 vs 0/26, p < 0.01). A cutoff value of the "time to eliminate VAs" > 7.0 s was able to predict a long-term recurrence of the VAs with 62.5% sensitivity and 85.7% specificity. CONCLUSIONS: The late cure of VAs occurs in more than one third of patients who have a seemingly unsuccessful ablation session, which is clustered in the first week after the procedure. However, long-term recurrence of VAs occurred in 37% of the late cure patients, emphasizing the importance of long-term follow-up. PMID- 29460234 TI - Implementation of a near-zero fluoroscopy approach in interventional electrophysiology: impact of operator experience. AB - PURPOSE: Catheter ablation is performed under fluoroscopic guidance. Reduction of radiation dose for patients and staff is emphasized by current recommendations. Previous studies have shown that lower operator experience leads to increased radiation dose. On the other hand, less experienced operators may depend even more on fluoroscopic guidance. Our study aimed to evaluate feasibility and efficacy of a non-fluoroscopic approach in different training levels. METHODS: From January 2017, a near-zero fluoroscopy approach was established in two centers. Four operators (beginner, 1st year fellow, 2nd year fellow, expert) were instructed to perform the complete procedure with the use of a 3-D mapping system without fluoroscopy. A historical cohort that underwent procedures with fluoroscopy use served as control group. Dose area product (DPA), procedure duration, acute procedural success, and complications were compared between the groups and for each operator. RESULTS: Procedures were performed in 157 patients. The first 100 patients underwent procedures with fluoroscopic guidance, the following 57 procedures were performed with the near-zero fluoroscopy approach. The results show a significant reduction in DPA for all operators immediately after implementation of the near-zero fluoroscopy protocol (control 637 +/- 611 MUGy/m2; beginner 44.1 +/- 79.5 MUGy/m2, p = 0.002; 1st year fellow 24.3 +/- 46.4.5 MUGy/m2, p = 0.001; 2nd year fellow 130.3 +/- 233.3 MUGy/m2, p = 0.003; expert 9.3 +/- 37.4 MUGy/m2, P < 0.001). Procedure duration, acute success, and complications were not significantly different between the groups. CONCLUSION: Our results show a 90% reduction of DPA shortly after implementation of a near zero fluoroscopy approach in interventional electrophysiology even in operators in training. PMID- 29460235 TI - Response and outcomes of cardiac resynchronization therapy in patients with renal dysfunction. AB - PURPOSE: Renal dysfunction is often associated with chronic heart failure, leading to increased morbi-mortality. However, data regarding these patients after cardiac resynchronization therapy (CRT) is sparse. We sought to evaluate response and long-term mortality in patients with heart failure and renal dysfunction and assess renal improvement after CRT. METHODS: We analyzed 178 consecutive patients who underwent successful CRT device implantation (age 64 +/- 11 years; 69% male; 92% in New York Heart Association (NYHA) functional class >= III; 34% with ischemic cardiomyopathy). Echocardiographic response was defined as >= 15% reduction in left ventricular end-systolic diameter and clinical response as a sustained improvement of at least one NYHA functional class. Renal dysfunction was defined as an estimated glomerular filtration rate (eGFR) below 60 mL/min/1.73 m2. RESULTS: Renal dysfunction was present in 34.7%. Renal dysfunction was not an independent predictor of echocardiographic response (OR 1.109, 95% CI 0.713-1.725, p 0.646) nor clinical response (OR 1.003; 95% CI 0.997 1.010; p 0.324). During follow-up (mean 55.2 +/- 32 months), patients with eGFR < 60mL/min/1.73 m2 had higher overall mortality (HR 4.902, 95% CI 1.118-21.482, p 0.035). However, clinical response in patients with renal dysfunction was independently associated with better long-term survival (HR 0.236, 95% CI 0.073 0.767, p 0.016). Renal function was significantly improved in patients who respond to CRT (DeltaeGFR + 5.5 mL/min/1.73 m2 at baseline vs. follow-up, p 0.049), while this was not evident in nonresponders. Improvements in eGFR of at least 10 mL/min/1.73 m2 were associated with improved survival in renal dysfunction patients (log-rank p 0.036). CONCLUSION: Renal dysfunction was associated with higher long-term mortality in CRT patients, though, it did not influence echocardiographic nor functional response. Despite worse overall prognosis, renal dysfunction patients who are responders showed long-term survival benefit and improvement in renal function following CRT. PMID- 29460236 TI - A double-blind, randomised, placebo-controlled, cross-over study assessing the use of XEN-D0103 in patients with paroxysmal atrial fibrillation and implanted pacemakers allowing continuous beat-to-beat monitoring of drug efficacy. AB - PURPOSE: The ultrarapid delayed rectifier current (IKur) carried by Kv1.5 channels, which are solely expressed in the atrium, is a potential target for safer treatment of paroxysmal atrial fibrillation (PAF). XEN-D0103 is a nanomolar ion channel blocker that selectively inhibits potassium ion flux through the Kv1.5 ion channel. The efficacy of XEN-D0103 in reducing AF burden was assessed in patients with DDDRp permanent pacemakers (PPMs) and PAF. METHODS: A double blind, placebo-controlled, cross-over study was performed in patients with PAF and DDDRp PPMs with advanced atrial and ventricular Holters allowing beat-to-beat arrhythmia follow-up. All anti-arrhythmic drugs were withdrawn before randomised treatment. After baseline assessment, patients were randomly assigned to two treatment periods of placebo then XEN-D0103 50 mg bd, or XEN-D0103 50 mg bd then placebo. RESULTS: Fifty-four patients were screened and 21 patients were eligible and included in the randomised trial. All 21 patients completed both treatment periods. The primary endpoint was change in AF burden assessed by PPM. There was no significant difference in AF burden on treatment with XEN-D0103 versus placebo. There was a reduction in the mean frequency of AF episodes (relative reduction 0.72, 95% CI 0.66 to 0.77; p < 0.0001). XEN-D0103 was safe and well tolerated, and there were no serious adverse events. XEN-D0103 did not have any apparent effect on heart rate compared to placebo. CONCLUSIONS: XEN-D0103 did not reduce AF burden in patients with PAF and dual chamber pacemakers providing beat to-beat monitoring. XEN-D0103 was well tolerated and did not have any apparent effect on heart rate. Although single-ion channel blockade with XEN-D0103 did not affect AF in this study, there might be a potential for this agent to be used in combination with other atrially specific drugs in the treatment of AF. EUDRACT TRIAL REGISTRATION NUMBER: 2013-004456-38. PMID- 29460237 TI - A Comparison of the Impacts of Wind Energy and Unconventional Gas Development on Land-use and Ecosystem Services: An Example from the Anadarko Basin of Oklahoma, USA. AB - The United States energy industry is transforming with the rapid development of alternative energy sources and technological advancements in fossil fuels. Two major changes include the growth of wind turbines and unconventional oil and gas. We measured land-use impacts and associated ecosystem services costs of unconventional gas and wind energy development within the Anadarko Basin of the Oklahoma Woodford Shale, an area that has experienced large increases in both energy sectors. Unconventional gas wells developed three times as much land compared to wind turbines (on a per unit basis), resulting in higher ecosystem services costs for gas. Gas wells had higher impacts on intensive agricultural lands (i.e., row crops) compared to wind turbines that had higher impacts on natural grasslands/pastures. Because wind turbines produced on average less energy compared to gas wells, the average land-use-related ecosystem cost per gigajoule of energy produced was almost the same. Our results demonstrate that both unconventional gas and wind energy have substantial impacts on land use, which likely affect wildlife populations and land-use-related ecosystem services. Although wind energy does not have the associated greenhouse gas emissions, we suggest that the direct impacts on ecosystems in terms of land use are similar to unconventional fossil fuels. Considering the expected rapid global expansion of these two forms of energy production, many ecosystems are likely to be at risk. PMID- 29460238 TI - Forward-looking farmers owning multiple potential wetland restoration sites: implications for efficient restoration. AB - Wetland restoration can increase the provision of multiple non-market ecosystem services. Environmental and socio-economic factors need to be accounted for when land is withdrawn from agriculture and wetlands are restored. We build multi objective optimization models to provide decision support for wetland restoration in the Le Sueur river watershed in Southern Minnesota. We integrate environmental objectives of sediment reduction and habitat protection with socio-economic factors associated with the overlap of private land with potential wetland restoration sites in the watershed and the costs representing forward-looking farmers voluntarily taking land out of agricultural production in favor of wetland restoration. Our results demonstrate that the inclusion of these factors early on in the restoration planning process affects both the total costs of the restoration project and the spatial distribution of optimally selected wetland restoration sites. PMID- 29460239 TI - Clinical and pathophysiological aspects of type 1 autoimmune pancreatitis. AB - In 1995, Yoshida and colleagues proposed the concept of "autoimmune pancreatitis" (AIP), which has recently been recognized as a new pancreatic inflammatory disease. Recent studies have suggested the existence of two subtypes of AIP: type 1, which involves immunoglobulin G4 (IgG4) and is the pancreatic manifestation of IgG4-related disease (IgG4-RD); and type 2, which is characterized by granulocytic epithelial lesions. Type 2 AIP is thought to be rare in Japan. Type 1 AIP is characterized by increased serum IgG4 concentrations, lymphoplasmacytic infiltrations, storiform fibrosis, and obliterative phlebitis. However, although type 1 AIP has become increasingly recognized, many clinical and basic issues remain to be solved. This review provides an overview of the recent clinical and basic knowledge of type 1 AIP.

PMID- 29460242 TI - Revisiting energy intensity convergence: new evidence from OECD countries. AB - In this study, we examine the energy intensity convergence in OECD countries within the context of recent developments in unit root analysis by paying attention to modeling structural shifts. We collect the total primary energy consumption/GDP data of 27 OECD countries during the period 1980-2014. The findings indicate that controlling for shifts plays a crucial role, and different approximations in modeling breaks lead to changes in inferences. In conclusion, we present some policy proposals. PMID- 29460241 TI - Ecological and human health risks arising from exposure to metals in urban soils under different land use in Nigeria. AB - The concentrations of eight metals (Cd, Pb, Cr, Ni, Cu, Mn, Zn and Fe) were measured in soils under different land use in an urban environment of the Niger Delta in Nigeria. The aim was to provide information on the potential ecological and human health risks associated with human exposure to metals in these soils. The potential ecological risk due to metals in soils of these land use types falls in the range of low to moderate ecological risk with a significant contribution from Cd. The severity of the individual metals to ecological risk in these land use types followed the order Cd > Pb > Zn > Cu > Ni > Cr > Mn. The non carcinogenic risk, expressed in terms of the hazard index (HI), arising through exposure to metals through oral, dermal and inhalation pathways, was greater than 1 for children in the majority of the land use types and less than 1 for adults for all land use types. This indicated that there are considerable non-cancer risks arising from childhood exposure to metals in soils of these land use types. The cancer risk values were within acceptable threshold values indicating a negligible cancer risk for both children and adults exposed to metals in these urban soils. PMID- 29460243 TI - Effect of spent mushroom substrate as a bulking agent on gaseous emissions and compost quality during pig manure composting. AB - The aim of this study was to investigate the gaseous emissions (CH4, N2O, and NH3) and compost quality during the pig manure composting by adding spent mushroom substrate (SMS) as a bulking agent. The control treatment was also studied using corn stalk (CS) as a bulking agent. The experiment was conducted in a pilot scale composting reactor under aerobic condition with the initial C/N ratio of 20. Results showed that bulking agents significantly affected gaseous emissions and compost quality. Using SMS as a bulking agent improved composting efficiency by shortening the time for maturity. SMS increased germination index and humic acid of the final compost (by 13.44 and 41.94%, respectively) compared with CS. Furthermore, composting with SMS as a bulking agent could reduce nitrogen loss, NH3, and N2O emissions (by 13.57, 35.56, and 46.48%, respectively) compared with the control. SMS slightly increased CH4 emission about 1.1 times of the CS. However, a 33.95% decrease in the global warming potential of CH4 and N2O was obtained by adding SMS treatment. These results indicate that SMS is a favorable bulking agent for reducing gaseous emissions and increasing compost quality. PMID- 29460244 TI - Rhizospheric effects on atrazine speciation and degradation in laterite soils of Pennisetum alopecuroides (L.) Spreng. AB - Atrazine (2-chloro-4-ethylamino-6-isopropylamino-1,3,5-triazine) is a worldwide used herbicide and often detected in agricultural soils and groundwater at concentrations above the permitted limit, because of its high mobility, persistence, and massive application. This study applied pot experiments to investigate the atrazine contents and speciation during the phytoremediation process by Pennisetum alopecuroides (L.) Spreng. in laterite soils. From the change of the total atrazine and bioavailable atrazine measured by diffusive gradients in thin film (DGT), P. alopecuroides significantly improved atrazine degradation efficiency from 15.22 to 51.46%, attributing to the increasing bioavailable atrazine in rhizosphere. Only a small amount of atrazine was taken up by P. alopecuroides root and the acropetal translocation from roots to shoots was limited. The atrazine speciation was significantly different between rhizosphere and non-rhizosphere, attributing to the declining pH and organic matters in rhizosphere. The relationship between pH and soil-bound/humus-fixed atrazine illustrated the pH-dependant release of the atrazine from soils and the competition between humus adsorption and uptake by P. alopecuroides. The present study reveals the important roles of soil pH and organic matters in atrazine speciation and availability in laterite soils, and provides new insights in the rhizospheric effects on effective phytoremediation of atrazine. PMID- 29460245 TI - Larvicidal activity of selected plant extracts and their combination against the mosquito vectors Culex quinquefasciatus and Aedes aegypti. AB - In order to develop an environment-friendly botanical mosquito larvicide alternative to the chemical larvicides, extracts were made from the leaves of Hyptis suaveolens, Lantana camara, Nerium oleander, and Tecoma stans with three organic solvents such as methanol (ME), chloroform (CH), and petroleum ether (PE) using a Soxhlet extractor. The plant extracts were screened for larvicidal activity individually and in combination against the larvae of Aedes aegypti and Culex quinquefasciatus as per WHO protocol. Among the extracts, the maximum larvicidal activity was shown by the PE extract of L. camara (LC50 10.63 mg/L) followed by the PE extract of T. stans (LC50 19.26 mg/L), ME extract of N. oleander (LC50 35.82 mg/L), and PE extract of H. suaveolens (LC50 38.39 mg/L) against Cx. quinquefasciatus. In the case of Ae. aegypti, the PE extract of T. stans showed maximum activity with LC50 value of 55.41 mg/L followed by H. suaveolens (LC50 64.49 mg/L), PE extract of L. camara (LC50 74.93 mg/L), and ME extract of N. oleander (LC50 84.09). A blend of these four extracts resulted in a combination with corresponding LC50 values of 4.32 and 7.19 mg/L against Cx. quinquefasciatus and Ae. aegypti. The predator safety factors were 12.55 and 20.88 for Gambusia affinis with respect to Aedes and Culex larvae for the extract combination. Chemical constituents in extracts were also identified by FT-IR and GC-MS data. The present investigations suggest the possible use of this blend of botanical extracts as an ideal ecofriendly, larvicide against Ae. aegypti and Cx. quinquefasciatus larvae. PMID- 29460246 TI - Fluorescence quenching of MoS2 nanosheets/DNA/silicon dot nanoassembly: effective and rapid detection of Hg2+ ions in aqueous solution. AB - Mercury (Hg) contamination of aquatic sites represents a serious risk for human health and the environment. Therefore, effective and rapid monitoring of Hg in aqueous samples is a challenge of timely importance nowadays. In the present study, a rapid and sensitive mercury sensor based on the fluorescence quenching of MoS2 nanosheets/DNA/silicon dot nanoassembly has been developed for the efficient detection of mercury(II) in aquatic environments. In this process, silicon dots were synthesized through one-step high-temperature calcinations and thermomagnesium reduction method at 900 degrees C using rice husk as a silicon source, which demonstrates superior photophysical properties and excitation dependent fluorescence behavior. The interaction between MoS2 nanosheets/DNA/silicon dot nanoassembly and Hg2+ ions was studied using photoluminescence spectroscopy. The addition of Hg2+ ions to the assay solution induced the detachment of fluorescent probe from the surface of MoS2 nanosheets. Thus, the fluorescent probes sustained its fluorescence intensity. The developed sensor was tested on various concentrations of Hg2+ ions ranging from 0 to 1000 nM as well as on various metal ions. In addition, MoS2 nanosheets/DNA/silicon dot nanoassembly fluorescent Hg sensor efficiently detected the presence of Hg2+ ions in real-time water samples, which was comparably detected by the conventional atomic absorbance spectrometer (AAS). Overall, our results highlighted the high reliability of the present approach for environmental monitoring of Hg2+ ions, if compared to that of the customary method with a lowest detection limit of 0.86 nM. PMID- 29460247 TI - Role of soil physicochemical properties in quantifying the fate of diuron, hexazinone, and metribuzin. AB - The physicochemical properties of soil are fundamental to quantification of the fate of herbicides. Thus, the aim of this research was to evaluate the fate of diuron, hexazinone, and metribuzin in five soils (Clay-1, Clay-2, Loam-1, Loam-2, and Sand), presenting variation in clay content, cation exchange capacity (CEC), pH, and organic carbon (OC). Herbicides radiolabeled with 14C were applied, and the 14C-CO2 released from mineralization was trapped in 0.2 mol L-1 sodium hydroxide solution. The degradation ratio, as well as herbicide-bound residues (non-extractable), transformation products, and residues extractable from soil, was also evaluated. Average 14C-CO2 evolution accumulated for diuron mineralization was higher (22.24%) than hexazinone (7.73%) and metribuzin (3.20%). The degradation time half-life (DT50) values for hexazinone correlated with soil OC content. Although no correlation between soil properties and DT50 values was found for metribuzin, the degradation rate and total degree of mineralization were low in sand soil for metribuzin. Regarding diuron, OC content and CEC value appear to be related to mineralization and degradation rate, respectively. Differences in soil properties can influence the persistence and fate of herbicides, affecting their impact on the environment, weed control, and possible effects on subsequent crops. PMID- 29460248 TI - Mediative mechanism of bicarbonate on anaerobic propionate degradation revealed by microbial community and thermodynamics. AB - Syntrophic acetogenesis of volatile fatty acids (VFAs) such as propionate and butyrate is considered as the rate-limiting step of anaerobic digestion. Though being extensively researched, the mechanism is not well understood as the main constraint on developing effective solutions to the practical problem. In the present research work, the mediation of methanogenic propionate degradation by exogenous bicarbonate was evaluated, while the mechanism was revealed by microbial community and thermodynamics. It was found that the exogenous bicarbonate not more than 0.10 mol/L acted as a mediative role to enrich syntrophic acetogenic bacteria and decrease the actual Gibbs free energy change (DeltaG) of syntrophic acetogenesis reaction, resulted in the increased degradation rate and methane production rate of propionate. The remarkably increased DeltaG of methanogenic propionate degradation by the exogenous bicarbonate more than 0.15 mol/L decreased the degradation rate and methane production rate of propionate, though the DeltaG of syntrophic acetogenesis reaction was also decreased by the exogenous bicarbonate. This research work provided a control strategy to enhance syntrophic acetogenesis, as well as the methanogenic VFAs degradation. PMID- 29460250 TI - Metals in Racomitrium lanuginosum from Arctic (SW Spitsbergen, Svalbard archipelago) and alpine (Karkonosze, SW Poland) tundra. AB - Arctic-alpine tundra habitats are very vulnerable to the input of relatively small amounts of xenobiotics, and thus their level in such areas must be carefully controlled. Therefore, we collected the terrestrial widespread moss Racomitrium lanuginosum (Hedw.) Brid. in Spitsbergen in the Arctic moss lichen tundra and, for comparison, in the Arctic-alpine tundra in the Karkonosze (SW Poland). Concentrations of the elements Cd, Co, Cr, Cu, Fe, Hg, Li, Mn, Mo, Na, Ni, Pb, V, and Zn in this species and in the parent rock material were measured. We tested the following hypothesis: R. lanuginosum from Spitsbergen contains lower metal levels than the species from the Karkonosze collected at altitudes influenced by long-range transport from former Black Triangle industry. Principal component and classification analysis (PCCA) ordination revealed that mosses of Spitsbergen were distinguished by a significantly higher Na concentration of marine spray origin and mosses of Karkonosze were distinguished by significantly higher concentrations of Cd, Cr, Cu, Fe, Hg, Li, Mn, Pb, V, and Zn probably from long-range atmospheric transport. The influence of the polar station with a waste incinerator resulted in significantly higher Co, Li, and Ni concentrations in neighbouring mosses in comparison with this species from other sites. This investigation contributes to the use of R. lanuginosum as a bioindicator for metal contamination in Arctic and alpine tundra regions characterised by severe climate habitats with a restricted number of species. This moss enables the control of pollution usually brought solely by long-range atmospheric transport in high mountains as well as in Arctic areas. PMID- 29460249 TI - Improving photoelectrochemical reduction of Cr(VI) ions by building alpha Fe2O3/TiO2 electrode. AB - Photoelectrochemical process is an environmentally friendly technology and has a wide application in the control of environmental pollutants. Efficient nanophotocatalysts responsive to visible light are still highly attractive. In this work, alpha-Fe2O3/TiO2 were grown on fluorine doped tin oxide (FTO) substrates by hydrothermal method for photoelectrochemical reduction of Cr(VI). Compared with the separate alpha-Fe2O3 and TiO2 electrodes, the composite alpha Fe2O3/TiO2 electrodes show higher photocurrent density. Under visible light irradiation, 100% removal efficiency of Cr(VI) was obtained after 40 min treatment. The composite alpha-Fe2O3/TiO2 electrodes showed an enhanced absorbance in visible light region and had good stability to photoelectrochemical reduction of Cr(VI). The role of hole scavengers (citric acid and oxalic acid) and pH values was systematically investigated. This novel intensification approach provides new insight on the application of photoelectrochemical reduction in environmental remediation. PMID- 29460251 TI - Comparison of emerging contaminants in receiving waters downstream of a conventional wastewater treatment plant and a forest-water reuse system. AB - Forest-water reuse (FWR) systems treat municipal, industrial, and agricultural wastewaters via land application to forest soils. Previous studies have shown that both large-scale conventional wastewater treatment plants (WWTPs) and FWR systems do not completely remove many contaminants of emerging concern (CECs) before release of treated wastewater. To better characterize CECs and potential for increased implementation of FWR systems, FWR systems need to be directly compared to conventional WWTPs. In this study, both a quantitative, targeted analysis and a nontargeted analysis were utilized to better understand how CECs release to waterways from an FWR system compared to a conventional treatment system. Quantitatively, greater concentrations and total mass load of CECs was exhibited downstream of the conventional WWTP compared to the FWR. Average summed concentrations of 33 targeted CECs downstream of the conventional system were ~ 1000 ng/L and downstream of the FWR were ~ 30 ng/L. From a nontargeted chemical standpoint, more tentatively identified chemicals were present, and at a greater relative abundance, downstream of the conventional system as well. Frequently occurring contaminants included phthalates, pharmaceuticals, and industrial chemicals. These data indicate that FWR systems represent a sustainable wastewater treatment alternative and that emerging contaminant release to waterways was lower at a FWR system than a conventional WWTP.

AB - The extent of heavy metal pollution and their impact on the various component of urban aquaculture pond (India) were investigated on the basis of seasonal variation. The water, sediment, and fish samples (Labeo rohita and Labeo bata) were collected and analyzed to assess the metal toxicity. In the sediment, geoaccumulation index (Igeo), contamination factor (CF), pollution load index (PLI), and ecological risk index (ERI) were calculated. The estimated daily dietary intake (EDI) for As, Cd, Cr, Mn, Pb, and Zn was estimated in adult and children on the basis an average amount of fish consumed by the Indian people and its associated health hazard with was also assessed in terms of target hazard quotients (THQs). The concentration of metals in all the analyzed samples was found higher during pre-monsoon season. While, in case of fish, L. bata species has higher metal accumulation rate during both the seasons than the L. rohita because of their bottom dweller feeding habit. The order of metals in L. bata muscles is Zn > Mn > Pb > Cr > As > Cd. The Igeo value for Zn (2.66 to 3.68) was found to be highest and followed by Cd (1.65 to 3.52) and Pb (1.52 to 2.55) indicating moderate to highly polluted sediment quality. The values of ERI were significantly high during pre-monsoon period and varied from 319 to 557, representing very high metal contamination. From the human health perspective, present study highlighted that the local inhabitants who rely on this valuable pond for fish consumption are exposed chronically to As and Pb pollution due to higher THQ values, especially from the intake of L. bata. PMID- 29460253 TI - Neuronal apoptosis in the brainstem medulla of sudden unexpected death in infancy (SUDI), and the importance of standardized SUDI classification. AB - The purpose of this study was to examine the neuronal expression of apoptotic markers in the rostral medulla of a newly characterized dataset of sudden unexpected death in infancy (SUDI), and to determine the impact of diagnostic groupings on these findings and whether they pertain to the intrinsic apoptotic pathway. Immunohistochemical staining was quantified to determine the percentage of neurons positive for active caspase-9 (specific to the intrinsic apoptotic pathway), active caspase-3 (common to the intrinsic and extrinsic apoptotic pathways) and Terminal deoxynucleotidyl transferase mediated dUTP nick-end labelling (TUNEL) (labels DNA fragmentation) in nine nuclei of the rostral medulla. Expression was compared between groups of SUDI infants where the cause of death was initially classified by a forensic pathologist or subsequently after reclassification by an expert panel using the San Diego Criteria. 68 SUDI infants were studied and originally classified as explained SUDI (n = 12), Sudden Infant Death Syndrome (SIDS) (n = 27) and undetermined (n = 29). Reclassification resulted in a decrease in the number of explained SUDI cases to 7 and a decrease in the number of undetermined cases to 4, with a corresponding increase in the number of SIDS cases to 57 (8 SIDS I; 49 SIDS II). The expression of apoptotic markers was similar in explained SUDI and SIDS I infants. However, TUNEL expression was greater in the cuneate (p < 0.001), vestibular (p = 0.01) and hypoglossal (p < 0.001) nuclei and active caspase-3 expression was lower in the arcuate nucleus (p = 0.037) in SIDS II compared to explained Sudden Unexpected Death in Infancy (eSUDI) infants. Compared to SIDS I infants, SIDS II infants had greater TUNEL expression in the dorsal motor nucleus of the vagus (p < 0.01) and greater active caspase-9 expression in the medial and spinal vestibular nuclei (p = <0.01). Changes in apoptotic expression predominated in SIDS II infants. We postulate that these are due to a combination of contributing risk factors including the presence of an upper respiratory tract infection and bed-sharing/co sleeping. The absence of changes in active caspase-9 expression compared to eSUDI indicates that the intrinsic apoptotic pathway is not upregulated in SIDS. PMID- 29460254 TI - Diagnosis of arterial gas embolism in SCUBA diving: modification suggestion of autopsy techniques and experience in eight cases. AB - The purpose of this study was to suggest modifications of autopsy techniques in order to improve post-mortem diagnosis of arterial gas embolism (AGE) based on multidisciplinary investigation of SCUBA diving fatalities. Five adult human cadavers from the voluntary donation program of the Human Anatomy Laboratory, and eight judicial autopsied bodies of SCUBA divers from the Forensic Pathology Service were assessed. Before performing any autopsies, we accessed the diving plan and the divers' profiles for each case. We then introduced a new dissection procedure that included identification, isolation, and manipulation of carotid, vertebral and thoracic arterial systems. The dissected vascular structures that allowed optimall isolation of the systemic arterial circulation were identified and ligated. In three of the eight judicial cases, we had a strongly suggestive history of arterial gas embolism following pulmonary barotrauma (PBt/AGE). In these cases, the additional arterial dissection allowed us to clearly diagnose AGE in one of them. The autopsy of the rest of the cases showed other causes of death such as asphyxia by drowning and heart attack. In all cases we were able to reject decompression sickness, and in some of them we showed the presence of artefacts secondary to decomposition and resuscitation maneuvers. These results allow us to suggest a specific autopsy technique divided into four steps, aimed at confirming or excluding some evidence of dysbaric disorders according to a re enactment of the incident. We have demonstrated the presence of large volumes of intravascular air, which is typical of PBt/AGE. PMID- 29460255 TI - Large-scale environmental degradation results in inequitable impacts to already impoverished communities: A case study from the floating villages of Cambodia. AB - Cambodian subsistence communities within the Tonle Sap Great Lake area rely on resource extraction from the lake to meet livelihood needs. These fishing communities-many of which consist of dwellings floating on the lake-face potentially profound livelihood challenges because of climate change and changing hydrology due to dam construction for hydroelectricity within the Mekong Basin. We conducted interviews across five village communities, with local subsistence fisher people in the Tonle Sap in 2015, and used thematic analysis methods to reveal a fishery system that is undergoing rapid ecological decline, with local fishing communities increasingly experiencing reductions in available fish stocks. As a result, over 100 000 people living in these communities are experiencing a direct loss of well-being and livelihood. We discuss these losses and consider their implications for the future viability of Cambodian floating village communities. PMID- 29460256 TI - Post-disaster agricultural transitions in Nepal. AB - In Spring 2015, a series of earthquakes and aftershocks struck Nepal. The earthquakes caused significant changes in labor and land availability, cash income needs, and land quality. We examine how these post-earthquake impacts converged with ongoing agricultural shifts. Earthquake-related socio-economic and landscape changes specifically motivate the adoption of cardamom, Amomum subulatum, a high-value ecologically beneficial, and low labor commercial crop. We investigate reasons for the increased interest in cardamom post-earthquake, and challenges associated with it. We find that adopting cardamom serves as an important post-disaster adaptation. However, more broadly, unevenly distributed interventions coupled with the high capital costs of agricultural transition exacerbate social differentiation in communities after the disaster. Adoption is often limited to economically better off smallholder farmers. This paper extends previous research on disasters and smallholder farming by highlighting the specific potential of disasters to accelerate agricultural transitions and resulting inequality from the changes. PMID- 29460257 TI - Analysis of Postprandial Glycemia in Relation to Metabolic Compensation and Other Observed Parameters of Outpatients with Type 2 Diabetes Mellitus in the Czech Republic. AB - INTRODUCTION: The goal of the study was to determine the level of metabolic compensation expressed by glycosylated hemoglobin, fasting plasma glucose, and postprandial glucose as determined after a standardized breakfast; further, to evaluate interrelationships between the studied parameters and postprandial glucose levels. METHODS: The study included 1055 patients with type 2 diabetes mellitus. Their fasting plasma glucose and postprandial glucose were measured before and after a standardized breakfast. Attending diabetologists completed a uniform questionnaire that included demographic data, type of antidiabetic treatment, duration of diabetes, latest glycosylated hemoglobin value, presence of dyslipidemia, and organic complications. RESULTS: Glycosylated hemoglobin < 53 mmol/mol was achieved in 363 (34.2%), postprandial glucose < 7.5 mmol/l in 211 (19.9%), and fasting plasma glucose < 6 mmol/l in 251 (23.7%) patients. Excellent metabolic compensation, indicated by all the above mentioned glycosylated hemoglobin, fasting plasma glucose, and postprandial glucose values simultaneously, was achieved in only 71 (6.7%) patients. Comparable to fasting plasma glucose and postprandial glucose values, correlation with glycosylated hemoglobin levels is statistically significant; however, there is no difference at different glycosylated hemoglobin levels. There was a significant correlation between dyslipidemia and postprandial glycemia (p = 0.013). CONCLUSION: The objective of care for patients with diabetes mellitus is to improve their long term metabolic compensation; to that end, both fasting plasma glucose and postprandial glucose deserve equal attention. PMID- 29460258 TI - Diabetes in the Elderly. AB - The elderly are an important and distinct yet heterogeneous group of persons living with diabetes. The elderly have a unique biomedical, psychological, and social constitution. Their needs are different from those of younger adults. This implies that special care must be taken while evaluating and planning their nursing and management. Diabetes management in the elderly should focus on prevention and limitation of geriatric syndromes (medical conditions encountered in elderly persons), hypoglycemia (low blood glucose), and neurocognitive dysfunction (impairment in the functioning of the nervous system and brain). This review takes a practical approach to the assessment, nursing care, and medical treatment of diabetes in the elderly. It highlights major challenges and suggests solutions to these commonly encountered clinical problems. PMID- 29460259 TI - Glucagon-Like Peptide-1 Receptor Agonist Use and Renal Impairment: A Retrospective Analysis of an Electronic Health Records Database in the U.S. Population. AB - INTRODUCTION: The study characterizes the use of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) in patients with type 2 diabetes (T2D) with and without renal impairment and examines the effects of such use on the clinical outcomes of estimated glomerular filtration rate (eGFR) and glycated hemoglobin (A1c). METHODS: Data from the Practice Fusion electronic health records database from 1 January 2012 through 30 April 2015 were used. Adults with T2D who received serum creatinine laboratory tests and initiated therapy with a GLP-1 RA (N = 3225) or other glucose-lowering agent (GLA) (N = 37,074) were included in the analysis. The GLP-1 RA cohort was matched to cohorts initiating therapy any other GLA, and multivariable analyses examined the association between GLP-1 RA use and changes in eGFR or A1c at 1 year after therapy initiation. RESULTS: In this study, only 5.7% of patients with an eGFR of < 30 and >= 15 mL/min/1.73 m2 and 3.6% of patients with an eGFR of < 15 mL/min/1.73 m2 initiated therapy with a GLP-1 RA. Compared to other GLAs, at 1-year after initiation of therapy the use of a GLP-1 RA was associated with a significantly smaller decline in eGFR (- 0.80 vs. - 1.03 mL/min/1.73 m2; P = 0.0005), a significantly smaller likelihood of having a >= 30% reduction in eGFR (2.19 vs. 3.14%; P < 0.0001), and a significantly larger reduction in A1c (- 0.48 vs. - 0.43; P = 0.0064). CONCLUSION: In clinical practice, the use of GLP-1 RAs in patients with a higher degree of renal impairment disease was limited. Compared to other GLAs, the use of GLP-1 RAs was associated with a significantly smaller decline in eGFR and a larger reduction in A1c over the 1 year following therapy initiation.

PMID- 29460260 TI - Clinical Benefit of Basal Insulin Analogue Treatment in Persons with Type 2 Diabetes Inadequately Controlled on Prior Insulin Therapy: A Prospective, Noninterventional, Multicenter Study. AB - INTRODUCTION: Basal insulin analogues offer persons with type 2 diabetes mellitus (T2DM) adequate glycemic control combined with a favorable safety profile. BASAL BALI-a prospective, noninterventional, multicenter disease registry-assessed the effectiveness and safety of basal insulin analogues in adult Serbians with T2DM previously inadequately controlled on other insulin types. METHODS: The primary objective was to assess the reduction in glycated hemoglobin (HbA1c) from basal insulin analogue initiation to the end of a 6-month observation period. Data collection was performed at three study visits: baseline, 3 months, and 6 months. All treatments and procedures were performed at the physicians' discretion. RESULTS: In total, 460 subjects were included. Mean diabetes duration was 11.6 +/ 6.6 years. Late complications of diabetes were present in 67% of subjects and comorbidities in 85%. After 6 months, the mean reduction in HbA1c was 1.8% (p < 0.01 vs. baseline); body weight (mean reduction of 0.9 kg, p < 0.01), waist circumference (1.5 cm, p < 0.01), and BMI (0.2 kg/m2, p < 0.01) were also reduced. A total of 49.1% of subjects reached their individualized HbA1c treatment target, and 42.0% met the composite HbA1c and fasting plasma glucose (FPG) target. The incidence of symptomatic hypoglycemia was reduced from 96.3% in the 6 months prior to initiating basal insulin analogues to 15.4% over the 6 month treatment period. CONCLUSION: Introducing basal insulin analogues in persons with T2DM previously inadequately controlled on other insulin types can significantly improve glycemic control and reduce the risk of hypoglycemia, without adversely affecting body weight.

AB - INTRODUCTION: Metabolic syndrome (MetS) is associated with an increased risk of major cardiovascular events. In women, increased serum uric acid (SUA) levels are associated with MetS and its components. However, whether baseline and changes in SUA predict incidence of MetS and its components remains unclear. METHODS: The subjects comprised 407 women aged 71 +/- 8 years from a rural village. We have identified participants who underwent a similar examination 11 years ago, and examined the relationship between baseline and changes in SUA, and MetS based on the modified criteria of the National Cholesterol Education Program's Adult Treatment Panel (NCEP-ATP) III report. RESULTS: Of these subjects, 83 (20.4%) women at baseline and 190 (46.7%) women at follow-up had MetS. Multiple linear regression analysis was performed to evaluate the contribution of each confounding factor for MetS; both baseline and changes in SUA as well as history of cardiovascular disease, low-density lipoprotein cholesterol, and estimated glomerular filtration ratio (eGFR) were independently and significantly associated with the number of MetS components during an 11-year follow-up. The adjusted odds ratios (ORs) (95% confidence interval) for incident MetS across tertiles of baseline SUA and changes in SUA were 1.00, 1.47 (0.82-2.65), and 3.11 (1.66-5.83), and 1.00, 1.88 (1.03-3.40), and 2.49 (1.38-4.47), respectively. In addition, the combined effect between increased baseline and changes in SUA was also a significant and independent determinant for the accumulation of MetS components (F = 20.29, p < 0.001). The ORs for incident MetS were significant only in subjects with age >= 55 years, decline in eGFR, and no baseline MetS. CONCLUSIONS: These results suggested that combined assessment of baseline and changes in SUA levels provides increased information for incident MetS, independent of other confounding factors in community-dwelling women. PMID- 29460263 TI - Methadone as anticancer treatment: hype, hope, or hazard? : A series of case reports and a short review of the current literature and recommendations of the societies. AB - Recently, the use of methadone in cancer patients has increased due to in vitro studies indicating that methadone is capable of inducing cell death. However, thus far there are no relevant clinical studies indicating that the use of methadone can prolong survival in cancer patients. Based on low-quality evidence, methadone is a drug that has similar analgesic benefits to morphine and has a role in the management of cancer pain in adults. Other opioids such as morphine, hydromorphone, and fentanyl are easier to manage but may be more expensive than methadone in many economies. Methadone is an opioid that is only approved for replacement therapy in Austria. Methadone can be used as a second- or third-line agent for severe cancer-related pain, but its use should be restricted to experts. Here we report a series of cases of patients who developed problems when using methadone as an antitumor treatment, with a brief review on the role of methadone as a pain medication and the current lack of value as an anti-tumor therapy. Methadone is not approved or recommended as an anticancer treatment in Austria or Germany. The Austrian Association for Hemato-oncology (OeGHO), the Austrian Association for the Management of Pain (OSG), and the Austrian Association for Palliative Care (OPG) do not recommend the use of methadone as an anticancer treatment. Thus, from a medical and ethical point of view, the use of methadone as an antitumor therapy is to be rejected, based on the views of various Austrian (OeGHO, OSG, OPG) and German specialists. Unqualified use of methadone by nonexperienced pain therapists is dangerous and must also be rejected. PMID- 29460264 TI - Acute myopathy as a side effect of electrostimulation. PMID- 29460262 TI - Physiologic effects of voice stimuli in conscious and unconscious palliative patients-a pilot study. AB - BACKGROUND: Sounds and acoustic stimuli can have an effect on human beings. In medical care, sounds are often used as parts of therapies, e. g., in different types of music therapies. Also, human speech greatly affects the mental status. Although calming sounds and music are widely established in the medical field, clear evidence for the effect of sounds in palliative care is scare, and data about effects of the human voice in general are still missing. Thus, the aim of this study was to evaluate the effects of different voice stimuli on palliative patients. METHODS: Two different voice stimuli (one calm, the other turbulent) were presented in a randomized sequence, and physiological parameters (blood pressure, heart frequency, oxygen saturation, respiratory rate) were recorded. RESULTS: Twenty patients (14 conscious and 6 unconscious) participated in this study. There was a decrease of heart frequency as well as an increase of oxygen saturation in the group of conscious patients, whereas no significant change of blood pressure or respiratory rate were detected in either group, conscious and unconscious patients. CONCLUSIONS: Although our dataset is heterogeneous, it can be concluded that voice stimuli can influence conscious patients. However, in this setting, no effect on unconscious patients was demonstrated. More clinical research on this topic with larger groups and a broader spectrum of parameters is needed. PMID- 29460265 TI - miRNA Editing: New Insights into the Fast Control of Gene Expression in Health and Disease. AB - Post-transcriptional modifications are essential mechanisms for mRNA biogenesis and function in eukaryotic cells. Beyond well-characterized events such as splicing, capping, and polyadenylation, there are several others, as RNA editing mechanisms and regulation of transcription mediated by miRNAs that are taking increasing attention in the last years. RNA editing through A-to-I deamination increases transcriptomic complexity, generating different proteins with amino acid substitution from the same transcript. On the other hand, miRNAs can regulate gene expression modulating target mRNA decay and translation. Interestingly, recent studies highlight the possibility that miRNAs might undergo editing themselves. This mainly translates in the degradation or uncorrected maturation of miRNAs but also in the recognition of different targets. The presence of edited and unedited forms of the same miRNA may have important biological implications in both health and disease. Here we review ongoing investigations on miRNA RNA editing with the aim to shed light on the growing importance of this mechanism in adding complexity to post-transcriptional regulation of gene expression. PMID- 29460266 TI - Increased Levels of Rictor Prevent Mutant Huntingtin-Induced Neuronal Degeneration. AB - Rictor associates with mTOR to form the mTORC2 complex, which activity regulates neuronal function and survival. Neurodegenerative diseases are characterized by the presence of neuronal dysfunction and cell death in specific brain regions such as for example Huntington's disease (HD), which is characterized by the loss of striatal projection neurons leading to motor dysfunction. Although HD is caused by the expression of mutant huntingtin, cell death occurs gradually suggesting that neurons have the capability to activate compensatory mechanisms to deal with neuronal dysfunction and later cell death. Here, we analyzed whether mTORC2 activity could be altered by the presence of mutant huntingtin. We observed that Rictor levels are specifically increased in the striatum of HD mouse models and in the putamen of HD patients. Rictor-mTOR interaction and the phosphorylation levels of Akt, one of the targets of the mTORC2 complex, were increased in the striatum of the R6/1 mouse model of HD suggesting increased mTORC2 signaling. Interestingly, acute downregulation of Rictor in striatal cells in vitro reduced mTORC2 activity, as shown by reduced levels of phospho-Akt, and increased mutant huntingtin-induced cell death. Accordingly, overexpression of Rictor increased mTORC2 activity counteracting cell death. Furthermore, normalization of endogenous Rictor levels in the striatum of R6/1 mouse worsened motor symptoms suggesting an induction of neuronal dysfunction. In conclusion, our results suggest that increased Rictor striatal levels could counteract neuronal dysfunction induced by mutant huntingtin. PMID- 29460267 TI - Hypoxia-Preconditioned Human Umbilical Vein Endothelial Cells Protect Against Neurovascular Damage After Hypoxic Ischemia in Neonatal Brain. AB - Therapy targeting the neurovascular unit may provide effective neuroprotection against neonatal hypoxia-ischemia (HI). We hypothesized that the peripheral injection of hypoxia-preconditioned human umbilical vein endothelial cells (HUVECs) following HI protects against neurovascular damage and provides long term neuroprotection in a postpartum (P) day-7 rat pup model. Compared with normoxic HUVECs, hypoxic HUVECs showed enhanced migration and angiogenesis in vitro and had augmented migration effects into the brain when administered intraperitoneally in vivo after HI. Moreover, 24 and 72 h post-HI, the hypoxic HUVECs group but not the normoxic HUVECs or culture-medium groups had significantly higher preservation of microvessels and neurons, and attenuation of blood-brain barrier damage than the normal-saline group. Compared to control or normal-saline groups, only the hypoxic HUVECs group had no impaired foot steps and showed a significant reduction of brain area loss at P42. Next-generation sequencing showed hypoxia-induced upregulation and downregulation of 209 and 215 genes in HUVECs, respectively. Upstream regulator analysis by ingenuity pathway analysis (IPA) identified hypoxia-inducible factor 1-alpha as the key predicted activated transcription regulator. After hypoxia, 12 genes (ADAMTS1, EFNA1, HIF1A, LOX, MEOX2, SELE, VEGFA, VEGFC, CX3CL1, HMMR, SDC, and SERPINE) associated with migration and/or angiogenesis were regulated in HUVECs. In addition, 6 genes (VEGFA, VEGFC, NTN4, TGFA, SERPINE1, and CX3CL1) involved in the survival of endothelial and neuronal cells were also markedly altered in hypoxic HUVECs. Thus, cell therapy by using hypoxic HUVECs that enhance migration and neurovascular protection may provide an effective therapeutic strategy for treating neonatal asphyxia. PMID- 29460268 TI - Interaction of Peptide Aptamers with Prion Protein Central Domain Promotes alpha Cleavage of PrPC. AB - Prion diseases are infectious and fatal neurodegenerative diseases affecting humans and animals. Transmission is possible within and between species with zoonotic potential. Currently, no prophylaxis or treatment exists. Prions are composed of the misfolded isoform PrPSc of the cellular prion protein PrPC. Expression of PrPC is a prerequisite for prion infection, and conformational conversion of PrPC is induced upon its direct interaction with PrPSc. Inhibition of this interaction can abrogate prion propagation, and we have previously established peptide aptamers (PAs) binding to PrPC as new anti-prion compounds. Here, we mapped the interaction site of PA8 in PrP and modeled the complex in silico to design targeted mutations in PA8 which presumably enhance binding properties. Using these PA8 variants, we could improve PA-mediated inhibition of PrPSc replication and de novo infection of neuronal cells. Furthermore, we demonstrate that binding of PA8 and its variants increases PrPC alpha-cleavage and interferes with its internalization. This gives rise to high levels of the membrane-anchored PrP-C1 fragment, a transdominant negative inhibitor of prion replication. PA8 and its variants interact with PrPC at its central and most highly conserved domain, a region which is crucial for prion conversion and facilitates toxic signaling of Abeta oligomers characteristic for Alzheimer's disease. Our strategy allows for the first time to induce alpha-cleavage, which occurs within this central domain, independent of targeting the responsible protease. Therefore, interaction of PAs with PrPC and enhancement of alpha cleavage represent mechanisms that can be beneficial for the treatment of prion and other neurodegenerative diseases. PMID- 29460269 TI - Novel Defense by Metallothionein Induction Against Cognitive Decline: From Amyloid beta1-42-Induced Excess Zn2+ to Functional Zn2+ Deficiency. AB - The role of metallothioneins (MTs) in cognitive decline associated with intracellular Zn2+ dysregulation remains unclear. Here, we report that hippocampal MT induction defends cognitive decline, which was induced by amyloid beta1-42 (Abeta1-42)-mediated excess Zn2+ and functional Zn2+ deficiency. Excess increase in intracellular Zn2+, which was induced by local injection of Abeta1-42 into the dentate granule cell layer, attenuated in vivo perforant pathway LTP, while the attenuation was rescued by preinjection of MT inducers into the same region. Intraperitoneal injection of dexamethasone, which increased hippocampal MT proteins and blocked Abeta1-42-mediated Zn2+ uptake, but not Abeta1-42 uptake, into dentate granule cells, also rescued Abeta1-42-induced impairment of memory via attenuated LTP. The present study indicates that hippocampal MT induction blocks rapid excess increase in intracellular Zn2+ in dentate granule cells, which originates in Zn2+ released from Abeta1-42, followed by rescuing Abeta1-42 induced cognitive decline. Furthermore, LTP was vulnerable to Abeta1-42 in the aged dentate gyrus, consistent with enhanced Abeta1-42-mediated Zn2+ uptake into aged dentate granule cells, suggesting that Abeta1-42-induced cognitive decline, which is caused by excess intracellular Zn2+, can more frequently occur along with aging. On the other hand, attenuated LTP under functional Zn2+ deficiency in dentate granule cells was also rescued by MT induction. Hippocampal MT induction may rescue cognitive decline under lack of cellular transient changes in functional Zn2+ concentration, while its induction is an attractive defense strategy against Abeta1-42-induced cognitive decline. PMID- 29460271 TI - SERPINA1 Gene Variants in Granulomatosis with Polyangiitis. AB - Alpha-1 antitrypsin (A1AT) deficiency is one of the most common genetic disorders in Caucasian population. There is a link between granulomatosis with polyangiitis (GPA) and most frequent variants of SERPINA1 gene encoding severe alpha-1 antitripsin deficiency. However, the potential effect of Pi*Z, Pi*S as well as other SERPINA1 variants on clinical course of vasculitis are not well understood. The aim of the study was to analyze the potential effect of A1AT protein phenotype representing the SERPINA1 gene variants on the clinical course of GPA. The study group consisted of 64 subjects with GPA, stratified according to the disease severity: patients in active phase (group I, n = 12), patients during remission on treatment (group II, n = 40) or untreated (group III, n = 12). Normal Pi*MM SERPINA1 genotype was detected by means of real-time polymerase chain reaction (PCR) or direct sequencing in 59 patients, Pi*MZ genotype in 2, and Pi*IM, Pi*MS or Pi*SZ in 1 patient respectively. The patients with abnormal Pi*Z, Pi*S, or Pi*I allele constituted 17% in group I, 5% in group II, and 8% in group III. The serum content of A1AT and high sensitivity C-reactive protein (hsCRP) assessed by nephelometry did not differ between the groups. Interestingly, the mean serum antiPR3-antibodies level detected by Elisa method was significantly greater in the GPA patients with Pi*Z, Pi*S, or Pi*I SERPINA1 variants than in the Pi*MM homozygotes. In summary, heterozygous Pi*MZ, Pi*MS, and Pi*SZ genotype was detected in 7.8% of total group of GPA patients, and in 10.5% of those with lung lesions. The abnormal alleles of Pi*S and Pi*Z may affect the clinical course of the disease. PMID- 29460270 TI - Towards a TDP-43-Based Biomarker for ALS and FTLD. AB - TDP-43 accumulates in nerve cells of nearly all cases of amyotrophic lateral sclerosis (ALS; the commonest form of motor neuron disease) and in the majority of Tau-negative frontotemporal lobar degeneration (FTLD). There is currently no biochemical test or marker of disease activity for ALS or FTLD, and the clinical diagnosis depends on the opinion of an experienced neurologist. TDP-43 has a key role in the pathogenesis of ALS/FTLD. Measuring TDP-43 in easily accessible biofluids, such as blood or cerebrospinal fluid, might reduce diagnostic delay and offer a readout for use in future drug trials. However, attempts at measuring disease-specific forms of TDP-43 in peripheral biofluids of ALS and FTLD patients have not yielded consistent results, and only some of the pathological biochemical features of TDP-43 found in human brain tissue have been detected in clinical biofluids to date. Reflecting on the molecular pathology of TDP-43, this review provides a critical overview on biofluid studies and future directions to develop a TDP-43-based clinical biomarker for ALS and FTLD. PMID- 29460272 TI - Hyperglycemia in Children Hospitalized with Acute Asthma. AB - Hyperglycemia is frequently observed in adults with acute asthma. We aimed to assess the frequency of hyperglycemia and its relation to outcomes in children admitted with acute asthma. In this retrospective study, we reviewed medical records of non-diabetic 166 children (66 girls) with the mean age of 5.4 +/- 2.6 years (range of 2-12 years), who were hospitalized with acute asthma between January 2012 through December 2014. Data pertaining to demographics, vital signs, oxygen saturation, serum blood glucose level, electrolytes, blood gases, and admission were collected. Children with other chronic conditions were excluded. The findings were that hyperglycemia (blood glucose >= 11.1 mmol/l) was observed in 38.6% of children. The median baseline blood glucose (IQR) was 9.8 mmol/l (7.2 13.3 mmol/l). Blood glucose level was associated with the length of hospitalization, with a median extension of 1.8 days, but was inversely associated with the serum potassium and bicarbonate levels. There were no associations between baseline blood glucose and age, gender, baseline respiratory rate, oxygen saturation, or intensive care admission. Hyperglycemia resolved spontaneously in all affected children. We conclude that hyperglycemia is common in children hospitalized with acute asthma. Hyperglycemia could be considered as a marker of a longer hospital stay. PMID- 29460273 TI - Pharmacogenetic Information in Clinical Guidelines: The European Perspective.

AB - Transepithelial electrical measurements in the renal tubule have provided a better understanding of how kidney regulates electrolyte and water homeostasis through the reabsorption of molecules and ions (e.g., H2 O and NaCl). While experiments and measurement techniques using native tissue are difficult to prepare and to reproduce, cell cultures conducted largely with the Ussing chamber lack the effect of fluid shear stress which is a key physiological stimulus in the renal tubule. To overcome these limitations, we present a modular perfusion chamber for long-term culture of renal epithelial cells under flow that allows the continuous and simultaneous monitoring of both transepithelial electrical parameters and transepithelial NaCl transport. The latter is obtained from electrical conductivity measurements since Na+ and Cl- are the ions that contribute most to the electrical conductivity of a standard physiological solution. The system was validated with epithelial monolayers of raTAL and NRK 52E cells that were characterized electrophysiologically for 5 days under different flow conditions (i.e., apical perfusion, basal, or both). In addition, apical to basal chemical gradients of NaCl (140/70 and 70/140 mM) were imposed in order to demonstrate the feasibility of this methodology for quantifying and monitoring in real time the transepithelial reabsorption of NaCl, which is a primary function of the renal tubule. PMID- 29460275 TI - Community screening for visual impairment in older people. AB - BACKGROUND: Visual problems in older people are common and frequently under reported. The effects of poor vision in older people are wide reaching and include falls, confusion and reduced quality of life. Much of the visual impairment in older ages can be treated (e.g. cataract surgery, correction of refractive error). Vision screening may therefore reduce the number of older people living with sight loss. OBJECTIVES: The objective of this review was to assess the effects on vision of community vision screening of older people for visual impairment. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2017, Issue 10); Ovid MEDLINE; Ovid Embase; the ISRCTN registry; ClinicalTrials.gov and the ICTRP. The date of the search was 23 November 2017. SELECTION CRITERIA: We included randomised controlled trials (RCTs) that compared vision screening alone or as part of a multi-component screening package as compared to no vision screening or standard care, on the vision of people aged 65 years or over in a community setting. We included trials that used self-reported visual problems or visual acuity testing as the screening tool. DATA COLLECTION AND ANALYSIS: We used standard methods expected by Cochrane. We graded the certainty of the evidence using GRADE. MAIN RESULTS: Visual outcome data were available for 10,608 people in 10 trials. Four trials took place in the UK, two in Australia, two in the United States and two in the Netherlands. Length of follow-up ranged from one to five years. Three of these studies were cluster randomised trials whereby general practitioners or family physicians were randomly allocated to undertake vision screening or no vision screening. All studies were funded by government agencies. Overall we judged the studies to be at low risk of bias and only downgraded the certainty of the evidence (GRADE) for imprecision.Seven trials compared vision screening as part of a multi-component screening versus no screening. Six of these studies used self-reported vision as both screening tool and outcome measure, but did not directly measure vision. One study used a combination of self-reported vision and visual acuity measurement: participants reporting vision problems at screening were treated by the attending doctor, referred to an eye care specialist or given information about resources that were available to assist with poor vision. There was a similar risk of "not seeing well" at follow-up in people screened compared with people not screened in meta-analysis of six studies (risk ratio (RR) 1.05, 95% confidence interval (CI) 0.97 to 1.14, 4522 participants high-certainty evidence). One trial reported "improvement in vision" and this occurred slightly less frequently in the screened group (RR 0.85, 95% CI 0.52 to 1.40, 230 participants, moderate certainty evidence).Two trials compared vision screening (visual acuity testing) alone with no vision screening. In one study, distance visual acuity was similar in the two groups at follow-up (mean difference (MD) 0.02 logMAR, 95% CI -0.02 to 0.05, 532 participants, high-certainty evidence). There was also little difference in near acuity (MD 0.02 logMAR, 95% CI -0.03 to 0.07, 532 participants, high-certainty evidence). There was no evidence of any important difference in quality of life (MD -0.06 National Eye Institute 25-item visual function questionnaire (VFQ-25) score adjusted for baseline VFQ-25 score, 95% CI 2.3 to 1.1, 532 participants, high-certainty evidence). The other study could not be included in the data analysis as the number of participants in each of the arms at follow-up could not be determined. However the authors stated that there was no significant difference in mean visual acuity in participants who had visual acuity assessed at baseline (39 letters) as compared to those who did not have their visual acuity assessed (35 letters, P = 0.25, 121 participants).One trial compared a detailed health assessment including measurement of visual acuity (intervention) with a brief health assessment including one question about vision (standard care). People given the detailed health assessment had a similar risk of visual impairment (visual acuity worse than 6/18 in either eye) at follow up compared with people given the brief assessment (RR 1.07, 95% CI 0.84 to 1.36, 1807 participants, moderate-certainty evidence). The mean composite score of the VFQ-25 was 86.0 in the group that underwent visual acuity screening compared with 85.6 in the standard care group, a difference of 0.40 (95% CI -1.70 to 2.50, 1807 participants, high-certainty evidence). AUTHORS' CONCLUSIONS: The evidence from RCTs undertaken to date does not support vision screening for older people living independently in a community setting, whether in isolation or as part of a multi component screening package. This is true for screening programmes involving questions about visual problems, or direct measurements of visual acuity.The most likely reason for this negative review is that the populations within the trials often did not take up the offered intervention as a result of the vision screening and large proportions of those who did not have vision screening appeared to seek their own intervention. Also, trials that use questions about vision have a lower sensitivity and specificity than formal visual acuity testing. Given the importance of visual impairment among older people, further research into strategies to improve vision of older people is needed. The effectiveness of an optimised primary care-based screening intervention that overcomes possible factors contributing to the observed lack of benefit in trials to date warrants assessment; trials should consider including more dependent participants, rather than those living independently in the community. PMID- 29460276 TI - Surgery for trigger finger. AB - BACKGROUND: Trigger finger is a common clinical disorder, characterised by pain and catching as the patient flexes and extends digits because of disproportion between the diameter of flexor tendons and the A1 pulley. The treatment approach may include non-surgical or surgical treatments. Currently there is no consensus about the best surgical treatment approach (open, percutaneous or endoscopic approaches). OBJECTIVES: To evaluate the effectiveness and safety of different methods of surgical treatment for trigger finger (open, percutaneous or endoscopic approaches) in adults at any stage of the disease. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase and LILACS up to August 2017. SELECTION CRITERIA: We included randomised or quasi-randomised controlled trials that assessed adults with trigger finger and compared any type of surgical treatment with each other or with any other non-surgical intervention. The major outcomes were the resolution of trigger finger, pain, hand function, participant-reported treatment success or satisfaction, recurrence of triggering, adverse events and neurovascular injury. DATA COLLECTION AND ANALYSIS: Two review authors independently selected the trial reports, extracted the data and assessed the risk of bias. Measures of treatment effect for dichotomous outcomes calculated risk ratios (RRs), and mean differences (MDs) or standardised mean differences (SMD) for continuous outcomes, with 95% confidence intervals (CIs). When possible, the data were pooled into meta-analysis using the random-effects model. GRADE was used to assess the quality of evidence for each outcome. MAIN RESULTS: Fourteen trials were included, totalling 1260 participants, with 1361 trigger fingers. The age of participants included in the studies ranged from 16 to 88 years; and the majority of participants were women (approximately 70%). The average duration of symptoms ranged from three to 15 months, and the follow-up after the procedure ranged from eight weeks to 23 months.The studies reported nine types of comparisons: open surgery versus steroid injections (two studies); percutaneous surgery versus steroid injection (five studies); open surgery versus steroid injection plus ultrasound-guided hyaluronic acid injection (one study); percutaneous surgery plus steroid injection versus steroid injection (one study); percutaneous surgery versus open surgery (five studies); endoscopic surgery versus open surgery (one study); and three comparisons of types of incision for open surgery (transverse incision of the skin in the distal palmar crease, transverse incision of the skin about 2-3 mm distally from distal palmar crease, and longitudinal incision of the skin) (one study).Most studies had significant methodological flaws and were considered at high or unclear risk of selection bias, performance bias, detection bias and reporting bias. The primary comparison was open surgery versus steroid injections, because open surgery is the oldest and the most widely used treatment method and considered as standard surgery, whereas steroid injection is the least invasive control treatment method as reported in the studies in this review and is often used as first-line treatment in clinical practice.Compared with steroid injection, there was low-quality evidence that open surgery provides benefits with respect to less triggering recurrence, although it has the disadvantage of being more painful. Evidence was downgraded due to study design flaws and imprecision.Based on two trials (270 participants) from six up to 12 months, 50/130 (or 385 per 1000) individuals had recurrence of trigger finger in the steroid injection group compared with 8/140 (or 65 per 1000; range 35 to 127) in the open surgery group, RR 0.17 (95% CI 0.09 to 0.33), for an absolute risk difference that 29% fewer people had recurrence of symptoms with open surgery (60% fewer to 3% more individuals); relative change translates to improvement of 83% in the open surgery group (67% to 91% better).At one week, 9/49 (184 per 1000) people had pain on the palm of the hand in the steroid injection group compared with 38/56 (or 678 per 1000; ranging from 366 to 1000) in the open surgery group, RR 3.69 (95% CI 1.99 to 6.85), for an absolute risk difference that 49% more had pain with open surgery (33% to 66% more); relative change translates to worsening of 269% (585% to 99% worse) (one trial, 105 participants).Because of very low quality evidence from two trials we are uncertain whether open surgery improve resolution of trigger finger in the follow up at six to 12 months, when compared with steroid injection (131/140 observed in the open surgery group compared with 80/130 in the control group; RR 1.48, 95% CI 0.79 to 2.76); evidence was downgraded due to study design flaws, inconsistency and imprecision. Low-quality evidence from two trials and few event rates (270 participants) from six up to 12 months of follow-up, we are uncertain whether open surgery increased the risk of adverse events (incidence of infection, tendon injury, flare, cutaneous discomfort and fat necrosis) (18/140 observed in the open surgery group compared with 17/130 in the control group; RR 1.02, 95% CI 0.57 to 1.84) and neurovascular injury (9/140 observed in the open surgery group compared with 4/130 in the control group; RR 2.17, 95% CI 0.7 to 6.77). Twelve participants (8 versus 4) did not complete the follow-up, and it was considered that they did not have a positive outcome in the data analysis. We are uncertain whether open surgery was more effective than steroid injection in improving hand function or participant satisfaction as studies did not report these outcomes. AUTHORS' CONCLUSIONS: Low-quality evidence indicates that, compared with steroid injection, open surgical treatment in people with trigger finger, may result in a less recurrence rate from six up to 12 months following the treatment, although it increases the incidence of pain during the first follow-up week. We are uncertain about the effect of open surgery with regard to the resolution rate in follow-up at six to 12 months, compared with steroid injections, due high heterogeneity and few events occurred in the trials; we are uncertain too about the risk of adverse events and neurovascular injury because of a few events occurred in the studies. Hand function or participant satisfaction were not reported. PMID- 29460277 TI - Plant responses to fertilization experiments in lowland, species-rich, tropical forests. AB - We present a meta-analysis of plant responses to fertilization experiments conducted in lowland, species-rich, tropical forests. We also update a key result and present the first species-level analyses of tree growth rates for a 15-yr factorial nitrogen (N), phosphorus (P), and potassium (K) experiment conducted in central Panama. The update concerns community-level tree growth rates, which responded significantly to the addition of N and K together after 10 yr of fertilization but not after 15 yr. Our experimental soils are infertile for the region, and species whose regional distributions are strongly associated with low soil P availability dominate the local tree flora. Under these circumstances, we expect muted responses to fertilization, and we predicted species associated with low-P soils would respond most slowly. The data did not support this prediction, species-level tree growth responses to P addition were unrelated to species-level soil P associations. The meta-analysis demonstrated that nutrient limitation is widespread in lowland tropical forests and evaluated two directional hypotheses concerning plant responses to N addition and to P addition. The meta-analysis supported the hypothesis that tree (or biomass) growth rate responses to fertilization are weaker in old growth forests and stronger in secondary forests, where rapid biomass accumulation provides a nutrient sink. The meta-analysis found no support for the long-standing hypothesis that plant responses are stronger for P addition and weaker for N addition. We do not advocate discarding the latter hypothesis. There are only 14 fertilization experiments from lowland, species-rich, tropical forests, 13 of the 14 experiments added nutrients for five or fewer years, and responses vary widely among experiments. Potential fertilization responses should be muted when the species present are well adapted to nutrient-poor soils, as is the case in our experiment, and when pest pressure increases with fertilization, as it does in our experiment. The statistical power and especially the duration of fertilization experiments conducted in old growth, tropical forests might be insufficient to detect the slow, modest growth responses that are to be expected.

AB - Biofilms alter their metabolism in response to environmental stress. This study explores the effect of a hyperosmotic agent-antibiotic treatment on the metabolism of Staphylococcus aureus biofilms through the use of nuclear magnetic resonance (NMR) techniques. To determine the metabolic activity of S. aureus, we quantified the concentrations of metabolites in spent medium using high resolution NMR spectroscopy. Biofilm porosity, thickness, biovolume, and relative diffusion coefficient depth profiles were obtained using NMR microimaging. Dissolved oxygen concentration was measured to determine the availability of oxygen within the biofilm. Under vancomycin-only treatment, the biofilm communities switched to fermentation under anaerobic condition, as evidenced by high concentrations of formate (7.4 +/- 2.7 mM), acetate (13.1 +/- 0.9 mM), and lactate (3.0 +/- 0.8 mM), and there was no detectable dissolved oxygen in the biofilm. In addition, we observed the highest consumption of pyruvate (0.19 mM remaining from an initial 40 mM concentration), the sole carbon source, under the vancomycin-only treatment. On the other hand, relative effective diffusion coefficients increased from 0.73 +/- 0.08 to 0.88 +/- 0.08 under vancomycin-only treatment but decreased from 0.71 +/- 0.04 to 0.60 +/- 0.07 under maltodextrin only and from 0.73 +/- 0.06 to 0.56 +/- 0.08 under combined treatments. There was an increase in biovolume, from 2.5 +/- 1 mm3 to 7 +/- 1 mm3 , under the vancomycin-only treatment, while the maltodextrin-only and combined treatments showed no significant change in biovolume over time. This indicated that physical biofilm growth was halted during maltodextrin-only and combined treatments. PMID- 29460280 TI - The protective effects of Sauropus spatulifolius on acute lung injury induced by lipopolysaccharide. AB - BACKGROUND: Sauropus spatulifolius Beille (named 'Long-Li-Ye' in China) is used to make 'herbal tea' to prevent pneumonia. This study aimed to evaluate the antioxidant activities in vitro and the protective effects of Long-Li-Ye on acute lung injury (ALI) induced by lipopolysaccharide (LPS). RESULTS: The supernatant after ethanol addition to Long-Li-Ye water extract (LLYCSL) and the resin eluting fraction of LLYCSL (LLY40) showed strong antioxidant activities in vitro. LLYCSL and LLY40 could attenuate ALI via decreasing myeloperoxidase activity, increasing superoxide dismutase activity and decreasing the levels of tumor necrosis factor alpha (TNF-alpha), interleukin 1beta (IL-1beta) and IL-6. In addition, LLY40 could increase catalase activity, increase the levels of IL-10, IL-4 and IL-13 and decrease the TNF-alpha/IL-10 ratio. CONCLUSION: Long-Li-Ye could be used as a natural antioxidant for food production and functional food or dietary supplementation for people with ALI. (c) 2018 Society of Chemical Industry. PMID- 29460281 TI - Alexithymia and risk preferences: Predicting risk behaviour across decision domains. AB - Risk-taking is a critical health factor as it plays a key role in several diseases and is related to a number of health risk factors. The aim of the present study is to investigate the role of alexithymia in predicting risk preferences across decision domains. One hundred and thirteen participants filled out an alexithymia scale (Toronto Alexithymia Scale-TAS-20), impulsivity and venturesomeness measures (I7 scale), and-1 month later-the Cognitive Appraisal of Risky Events (CARE questionnaire). The hierarchical regression analyses showed that alexithymia positively predicted risk preferences in two domains: aggressive/illegal behaviour and irresponsible academic/work behaviour. The results also highlighted a significant association of the alexithymia facet, externally oriented thinking (EOT), with risky sexual activities. EOT also significantly predicted aggressive/illegal behaviour and irresponsible academic/work behaviour. The alexithymia facet, Difficulty Identifying Feelings, significantly predicted irresponsible academic/work behaviour. The results of the present study provide interesting insights into the connection between alexithymia and risk preferences across different decision domains. Implications for future studies and applied interventions are discussed.

PMID- 29460282 TI - The versatility of the CD1 lipid antigen presentation pathway. AB - The family of non-classical major histocompatibility complex (MHC) class-I like CD1 molecules has an emerging role in human disease. Group 1 CD1 includes CD1a, CD1b and CD1c, which function to display lipids on the cell surface of antigen presenting cells for direct recognition by T-cells. The recent advent of CD1 tetramers and the identification of novel lipid ligands has contributed towards the increasing number of CD1-restricted T-cell clones captured. These advances have helped to identify novel donor unrestricted and semi-invariant T-cell populations in humans and new mechanisms of T-cell recognition. However, although there is an opportunity to design broadly acting lipids and harness the therapeutic potential of conserved T-cells, knowledge of their role in health and disease is lacking. We briefly summarize the current evidence implicating group 1 CD1 molecules in infection, cancer and autoimmunity and show that although CD1 are not as diverse as MHC, recent discoveries highlight their versatility as they exhibit intricate mechanisms of antigen presentation. PMID- 29460284 TI - Dementia and Risk of 30-Day Readmission in Older Adults After Discharge from Acute Care Hospitals. AB - OBJECTIVES: To assess the association between dementia and risk of hospital readmission and to evaluate whether the effect of dementia on hospital readmission varies according to primary diagnosis. DESIGN: Retrospective cohort study. SETTING: Nationwide discharge database of acute care hospitals in Japan. PARTICIPANTS: Individuals aged 65 and older diagnosed with one of the 30 most common diagnoses and discharged from 987 hospitals between April 2014 and September 2015 (N = 1,834,378). MEASUREMENTS: The primary outcome was unplanned hospital readmission within 30 days. Poisson generalized estimating equation models were fitted to assess the risks of readmission for individuals with and without dementia, using primary diagnosis as a possible effect modifier and clinical factors as potential confounders. RESULTS: The overall prevalence of dementia was 14.7% and varied according to primary diagnosis, ranging from 3.0% in individuals with prostate cancer to 69.4% in those with aspiration pneumonia. Overall, individuals with dementia had a higher risk of hospital readmission (8.3%) than those without (4.1%) (adjusted risk ratio (aRR])=1.46, 95% confidence interval (CI)=1.44-1.49), although diagnostic category substantially modified the relationship between dementia and hospital readmission. For hip fracture, dementia was associated with greater risk of hospital readmission (adjusted risk 11.5% vs 7.9%; aRR=1.46; 95% CI=1.28-1.68); this risk was attenuated for cholecystitis (adjusted risk 12.8% vs 12.4%; aRR=1.03; 95% CI=0.90-1.18). CONCLUSION: Risk of hospital readmission associated with dementia varied according to primary diagnosis. Healthcare providers could enforce interventions to minimize readmission by focusing on comorbid conditions in individuals with dementia and specific primary diagnoses that increase their risk of readmission.

AB - Xylose is a major component of lignocellulosic biomass, one of the most abundant feedstocks for biofuel production. Therefore, efficient and rapid conversion of xylose to ethanol is crucial in the viability of lignocellulosic biofuel plants. In this study, RNAi Assisted Genome Evolution (RAGE) was used to improve the xylose utilization rate in SR8, one of the most efficient publicly available xylose utilizing Saccharomyces cerevisiae strains. To identify gene targets for further improvement, we created a genome-scale library consisting of both genetic over-expression and down-regulation mutations in SR8. Followed by screening in media containing xylose as the sole carbon source, yeast mutants with 29% faster xylose utilization, and 45% higher ethanol productivity were obtained relative to the parent strain. Two known and two new effector genes were identified in these mutant strains. Notably, down-regulation of CDC11, an essential gene, resulted in faster xylose utilization, and this gene target cannot be identified in genetic knock-out screens. PMID- 29460287 TI - Chromosomal aberrations and CNVs in twin fetuses with cardiovascular anomalies: Comparison between monochorionic diamniotic and dichorionic diamniotic twins. AB - OBJECTIVE: To investigate the types of cardiovascular anomalies and the results of invasive prenatal diagnosis in twin fetuses. METHODS: A total of 298 fetuses in 149 twin pairs were enrolled, in which 1 or 2 fetuses of a twin pair had cardiovascular anomalies. Prenatal diagnosis was performed on 290 fetuses of 149 twin pairs, including 150 monochorionic diamniotic (MCDA) fetuses (79 pairs) and 140 dichorionic diamniotic (DCDA) fetuses (70 pairs). G-Banding karyotyping and/or chromosomal microarray analysis were performed. The types of cardiovascular anomalies and the results of prenatal diagnosis were analyzed. RESULTS: Fifty percent (79/158) fetuses in MCDA group and 52.1% (73/140) fetuses in DCDA group were diagnosed with cardiovascular anomalies by ultrasound. Primary cardiac structural defects such as septal defects and tetralogy of Fallot were more common in DCDA group than in MCDA group, while acardiac anomaly was the most common in MCDA group. Chromosomal aberrations were identified in 7.7% fetuses (11/142) of MCDA group and in 18.3% fetuses (22/120) of DCDA group by G-banding karyotyping. Except benign copy number variations (CNVs), 37 CNVs (pathogenic, likely pathogenic, and variant of uncertain significance) and chromosomal aberrations were detected in 21.3% (32/150) fetuses of MCDA group and 47 CNVs (pathogenic, likely pathogenic, and variant of uncertain significance) and chromosomal aberrations were detected in 32.1% (45/140) fetuses of DCDA group by chromosomal microarray analysis. CONCLUSIONS: Most of cardiovascular anomalies were identified in one fetus of a twin pair no matter in MCDA or DCDA twin. Primary cardiac structural defects were more common in DCDA group. Monozygotic twins may have discordant phenotypes, karyotypes, and CNVs between 2 fetuses of each pair. PMID- 29460288 TI - Pharmacokinetics of multiple doses of transdermal flunixin meglumine in adult Holstein dairy cows. AB - A transdermal formulation of the nonsteroidal anti-inflammatory drug, flunixin meglumine, has been approved in the United States and Canada for single-dose administration. Transdermal flunixin meglumine was administered to 10 adult Holstein cows in their second or third lactation at the label dose of 3.33 mg/kg every 24 hr for three total treatments. Plasma flunixin concentrations were determined using high-pressure liquid chromatography with mass spectroscopy (HPLC MS). Pharmacokinetic analysis was completed on each individual animal with noncompartmental methods using computer software. The time to maximum drug concentration (Tmax) was 2.81 hr, and the maximum drug concentration was 1.08 MUg/ml. The mean terminal half-life (T1/2) was determined to be 5.20 hr. Clearance per fraction absorbed (Cl/F) was calculated to be 0.294 L/hr kg-1 , and volume of distribution of fraction (Vz/F) absorbed was 2.20 L/kg. The mean accumulation factor was 1.10 after three doses. This indicates changes in dosing may not be required when giving multiple doses of flunixin transdermal. Further work is required to investigate the clinical efficacy of transdermal flunixin after multiple daily doses. PMID- 29460289 TI - Endogenous factors and mechanisms of renoprotection and renal repair. AB - BACKGROUND: An imbalance between renal damaging molecules and nephroprotective factors contributes to the development and progression of kidney diseases. Molecules with renoprotective properties might serve as biomarkers, drug targets as well as therapeutic options themselves. MATERIALS AND METHODS: For this review, we generated a set of renoprotective factors based on GeneRIF (Gene Reference Into Function) information available at NCBI's PubMed. The final set of manually curated renoprotective factors was investigated with respect to tissue specific expression, subcellular location distribution and involvement in biological processes using information from gene ontology as well as information from protein-protein interaction databases. We furthermore investigated the factors in the context of clinical trials of renal disease and diabetes. RESULTS: One hundred and ninety-three factors could be retrieved from the set of GeneRIFs on nephroprotection and renal repair. A large number of factors were either secretory molecules or plasma membrane receptors. Next to the elevated expression in renal tissue, also higher expression in connective tissue and pancreas was observed. The proteins could be assigned to the broad functional categories of cell proliferation and signalling, inflammatory response, apoptosis, blood pressure regulation as well as cellular response to different kinds of insults such as hypoxia, heat or mechanical stimulus. Eight factors are studied in clinical trials with additional ones being targeted by compounds. CONCLUSIONS: We have generated a set of renoprotective factors based on the literature information, which was functionally annotated and evaluated with respect to tested compounds in kidney disease and diabetes clinical trials. PMID- 29460290 TI - Extent of lymph node dissection improves survival in prostate cancer patients treated with radical prostatectomy without lymph node invasion. AB - PURPOSE: To assess the effect of pelvic lymph node dissection (PLND) extent on cancer-specific mortality (CSM) in prostate cancer (PCa) patients without lymph node invasion (LNI) treated with radical prostatectomy (RP). METHODS: Within the Surveillance, Epidemiology, and End results (SEER) database (2004-2014), we identified patients with D'Amico intermediate- or high-risk characteristics who underwent RP with PLND, without evidence of LNI. First, multivariable logistic regression models tested for predictors of more extensive PLND, defined as removed lymph node count (NRN) >=75th percentile. Second, Kaplan-Meier analyses and multivariable Cox regression models tested the effect of NRN >=75th percentile on CSM. Finally, survival analyses were repeated using continuously coded NRN. RESULTS: In 28 147 RP and PLND patients without LNI, 67.3% versus 32.7% exhibited D'Amico intermediate- or high-risk characteristics. The median NRN was 6 (IQR 3-10), the 75th percentile defined patients with NRN >=11. Patients with NRN >=11 had higher rate of cT2/3 stage (29.8 vs 26.1%), GS >=8 (25.7 vs 22.4%), and respectively more frequently exhibited D'Amico high-risk characteristics (34.6 vs 32.1%). In multivariable logistic regression models predicting the probability of more extensive PLND (NRN >=11), higher biopsy GS, higher cT stage, higher PSA, more recent year of diagnosis, and younger age at diagnosis represented independent predictors. At 72 months after RP, CSM-free rates were 99.5 versus 98.1% for NRN >=11 and NRN <=10, respectively and resulted in a HR of 0.50 (P = 0.01), after adjustment for all covariates. Similarly, continuously coded NRN achieved independent predictor status (HR: 0.955, P = 0.01), where each additional removed lymph node reduced CSM risk by 4.5%. CONCLUSION: More extensive PLND at RP provides improved staging information and consequently is associated with lower CSM in D'Amico intermediate- and high-risk PCa patients without evidence of LNI. Hence, more extensive PLND should be recommended in such individuals. PMID- 29460291 TI - Theoretical study of the effect of piezoelectric bone matrix on transient fluid flow in the osteonal lacunocanaliculae. AB - A new theoretical generation mechanism of the transient streaming potential considering variations in the surface potential on the wall in a lacunocanalicular system, is proposed based on the assumption of the piezoelectric bone matrix. To obtain the streaming potential analytically, a modified transient charge density equation is proposed. An osteon is modeled as a piezoelectric solid phase having fluid-filled cavities (lacunae) connected by channels (canaliculae) to obtain the pressure gradients in the canaliculae and the electric boundary conditions on the canalicular walls. In addition, this study focused on modeling of the negatively charged glycocalyx that fills the annular fluid space between the osteocytic process and the canalicular wall. It is assumed that the annular fluid space of the canaliculi can be represented as a two-layer configuration for flow through a gap (between the tips of the glycocalyx and the canalicular wall) overlaying the porous glycocalyx. The transient streaming potential and bone fluid flow affected by the generated total potential are analyzed using the one-dimensional lacunocanalicular fluid path, which is surrounded by the piezoelectric bone matrix. A significant increase in the streaming potential is predicted for the case with piezoelectricity. The peak streaming potential value with the piezoelectricity is found to be up to 58.8% greater compared with that without piezoelectricity. The electroviscous effect due to the total electric potential gradients on the fluid velocities in the canaliculi is negligible. These findings imply that the piezoelectric effect caused by deformation of the bone matrix should be considered for prediction of the streaming potential in the lacunocanaliculae.

We compared the rate of clinical outcomes between 2-7 and >=8 days of SAP in first fresh embryo transfer after intracytoplasmic sperm injection (ICSI) in groups of young maternal age (YMA: <38 years) and old maternal age (OMA: >=38 years). We conducted a retrospective study of 449 first ICSI cycles with a normal ovarian response. SAP was identified before collecting the semen samples. Semen analysis was performed based on the guidelines recommended by WHO (2010). Sperm preparation was made using the swim-up method. Patients' baseline characteristics in the YMA and OMA groups did not differ. The rates of fertilisation, top-quality embryos on day 3, biochemical pregnancy, clinical pregnancy, ongoing pregnancy, abortion and implantation per cycle were not significantly different between 2-7 and >=8 days of SAP in the YMA or OMA group. In conclusion, SAP beyond the recommended period by WHO was not associated with the rates of a lower fertilisation and pregnancy in human in vitro fertilisation (IVF). We think that a new criterion of SAP for clinical application in human IVF needs to be considered by WHO. PMID- 29460294 TI - Varicocelectomy with primary gubernaculum veins closure: A randomised clinical trial. AB - To evaluate the effect of microsurgical inguinal varicocelectomy with testicular delivery on semen parameters. A total of 416 patients, diagnosed with grade III varicocele, were randomised into two groups. One group underwent microsurgical inguinal varicocelectomy without testicular delivery. For the other group, testicular delivery and ligation of gubernacular and all collateral veins were performed. A semen analysis was performed before and 6 months after the procedure. Mean age of the patients in the case and control groups was 27.3 +/- 6.1 years and 25.9 +/- 4.6 years respectively (p = .1). The total number of recurrence after 6 months in the conventional and testicular delivery groups was 13 (6.5%) and 3 (1.5%) (p < .05). No case of hydrocele formation was observed in any of the groups. All sperm parameters were improved 6 months after the surgery in both groups. But comparing the mean improved difference between the two groups revealed a significant difference in improvement in sperm motility for patients who had undergone varicocelectomy with testicular delivery (p = .05). Microsurgical inguinal varicocelectomy is a safe and efficient technique with a minimum chance of post-operative complications and recurrence and also may have role in improvement of sperm motility compared with conventional techniques.

AB - OBJECTIVES: Health systems face resource and time barriers to developing and implementing cancer survivorship care plans (SCPs) when active cancer treatment is completed. To address this problem, the South Dakota (SD) Department of Health partnered with two of SD's largest health systems to create the SD Survivorship Program. The purpose of this program evaluation study was to describe and compare SCP development and implementation at the two health systems. DESIGN & SAMPLE: A descriptive qualitative design was used. Interview participants were instrumental in the development and implementation of SCPs within their respective health system. MEASURES: Content analysis was used to analyze the interview data. RESULTS: The two health systems used similar processes for (a) early designation of program personnel, (b) developing SCP templates, (c) provider/staff input, and (d) identifying/tracking eligible patients. In contrast, they developed differing processes for SCP completion and delivery. The two health systems also identified effective strategies and challenges in SCP development and implementation. CONCLUSION: This evaluation suggests that partnerships between state health departments and local health systems could be key for meeting the nation-wide goal of universal SCP implementation. Particularly, other low-population rural states like SD can use the findings to help build their SCP programs.

AB - Knowledge on genetic and environmental (G * E) interaction effects on cardiometabolic risk factors (CMRFs) in children is limited. The purpose of this study was to examine the impact of G * E interaction effects on CMRFs in Mexican American (MA) children (n = 617, ages 6-17 years). The environments examined were sedentary activity (SA), assessed by recalls from "yesterday" (SAy) and "usually" (SAu) and physical fitness (PF) assessed by Harvard PF scores (HPFS). CMRF data included body mass index (BMI), waist circumference (WC), fat mass (FM), fasting insulin (FI), homeostasis model of assessment-insulin resistance (HOMA-IR), high density lipoprotein cholesterol (HDL-C), triglycerides (TG), systolic (SBP) and diastolic (DBP) blood pressure, and number of metabolic syndrome components (MSC). We examined potential G * E interaction in the phenotypic expression of CMRFs using variance component models and likelihood-based statistical inference. Significant G * SA interactions were identified for six CMRFs: BMI, WC, FI, HOMA IR, MSC, and HDL, and significant G * HPFS interactions were observed for four CMRFs: BMI, WC, FM, and HOMA-IR. However, after correcting for multiple hypothesis testing, only WC * SAy, FM * SAy, and FI * SAu interactions became marginally significant. After correcting for multiple testing, most of CMRFs exhibited significant G * E interactions (Reduced G * E model vs. Constrained model). These findings provide evidence that genetic factors interact with SA and PF to influence variation in CMRFs, and underscore the need for better understanding of these relationships to develop strategies and interventions to effectively reduce or prevent cardiometabolic risk in children.

PMID- 29460296 TI - An exploratory analysis of the influence of personality and emotional factors on cerebral blood flow responses during painful stimulation in Fibromyalgia. AB - This study explored the influence of certain personality traits (neuroticism, extraversion, psychoticism, alexithymia), emotional variables (depression, catastrophizing), and insomnia on cerebral blood flow (CBF) responses to painful stimulation in fibromyalgia, using functional transcranial Doppler sonography. CBF velocities were recorded bilaterally in the anterior cerebral arteries (ACA) and middle cerebral arteries (MCA) of 24 fibromyalgia patients during exposure to two painful pressure conditions: (1) fixed pressure (2.4 kg) and (2) an individually calibrated pressure to produce an equal-moderate subjective pain intensity in all participants (average, 3.5 kg). Psychological factors were assessed by means of questionnaires. Neuroticism, and the externally-oriented thinking dimension of alexithymia were positively, and extraversion was inversely, associated with specific components of ACA and MCA CBF responses. Regarding catastrophizing and depression, correlations were positive for the fixed pressure condition and negative for the equal subjective intensity condition. The findings suggest that alterations in central nervous pain processing in fibromyalgia vary according to psychological factors. While most of the observed associations reflect a linear increase in nociceptive processing with the magnitude of negative cognitive and emotional states, the inverse associations for catastrophizing and depression during more intense painful stimulation may be ascribed to anti-nociceptive effects due to activation of the defense reflex. PMID- 29460298 TI - Inverse association of insulin antibody levels with insulin sensitivity in adults with Type 1 diabetes. AB - AIMS: Insulin resistance may contribute to the pathogenesis of autoimmune mediated diabetes. Antibodies against beta-cell-associated molecules, comprising islet cell antigen (ICA), glutamic acid decarboxylase (GAD) and insulin, characterize the autoimmune process. Because the link between insulin resistance and autoimmunity might be relevant for disease progression and treatment, we hypothesized that insulin resistance associates positively with beta-cell directed antibodies in newly diagnosed Type 1 diabetes. METHODS: Within the German Diabetes Study, an observational study including adults with newly diagnosed diabetes, 142 adults [84 men, 58 women; age 33.1 (26.4, 41.9) years; diabetes duration 6.3 (4.2, 9.1) months] positive for at least one antibody against ICA, GAD or insulin underwent hyperinsulinaemic-euglycaemic clamp tests to assess insulin sensitivity (M-value) in a cross-sectional setting. RESULTS: Insulin-directed antibodies were inversely correlated with M-values (beta = 0.039). Albeit not strong, the association persisted after adjustment for age, sex and BMI, and even after further adjustment for confounders reflecting exposure to exogenous insulin and residual beta-cell secretory capacity. Correlation network-based analyses revealed a complex interaction between levels of fasting insulin and of insulin antibodies with respect to their relationship with the M-value. GAD- or ICA-directed antibodies did not correlate with insulin sensitivity. CONCLUSIONS: In adults with recent-onset Type 1 diabetes expressing at least one beta-cell-directed antibody, insulin sensitivity is inversely related to insulin antibody titres, but not to other autoantibodies. Our finding may allow for the identification of insulin resistance in adults with high levels of insulin antibodies. PMID- 29460299 TI - Postnatal depression in a community-based study of women with polycystic ovary syndrome. AB - INTRODUCTION: Women with polycystic ovary syndrome are susceptible to depression and anxiety and so may also be at risk for postnatal depression. This study investigates whether women with polycystic ovary syndrome have an elevated risk of postnatal depression. MATERIAL AND METHODS: Cross-sectional data for parous women (n = 566) were available from a birth cohort. Polycystic ovary syndrome was diagnosed using the Rotterdam criteria. Details of reproductive history, pregnancy, birth, and postnatal depression were obtained through structured interview. Comparisons were made between women with and without polycystic ovary syndrome using logistic regression analysis, including the investigation of interactions. RESULTS: A positive but statistically non-significant association was found between polycystic ovary syndrome and postnatal depression (odds ratio 1.6, 95% confidence interval 0.9-2.9). Compared with their counterparts, women with polycystic ovary syndrome were substantially more likely: to have difficulty conceiving (odds ratio 5.2, 95% confidence interval 2.9-9.4), to have conceived with medical assistance (odds ratio 11.6, 95% confidence interval 5.5-24.4), and to have pregnancy complications (gestational diabetes, pregnancy-induced hypertension, or preeclampsia; odds ratio 2.0, 95% confidence interval 1.1-3.5). Where women with polycystic ovary syndrome had a history of miscarriage or conceived with medical assistance, the combination interacted (p = 0.06 and p < 0.05, respectively), with over half of such women having postnatal depression. CONCLUSIONS: Although women with polycystic ovary syndrome may not have an excess risk of postnatal depression overall, those who had suffered a miscarriage or required medical assistance to conceive were at substantially elevated risk. Findings point to vulnerability inherent in polycystic ovary syndrome being amplified, either by stressful experiences on the pathway to pregnancy/childbirth or by specific fertility treatment regimens. PMID- 29460300 TI - Catheter-associated venous air embolism in hospitalized horses: 32 cases. AB - BACKGROUND: Venous air embolism is a potentially life-threatening complication of IV catheter use in horses. Despite widespread anecdotal reports of their occurrence, few cases have been reported in the literature and the prognosis is currently unknown. HYPOTHESIS/OBJECTIVES: Our objective was to describe the surrounding circumstances, clinical signs, treatment, progression, and outcome of venous air embolism in hospitalized horses. ANIMALS: Thirty-two horses with acute onset of compatible clinical signs associated with IV catheter disconnection or damage. METHODS: Multicenter retrospective study. Data extracted from clinical records included signalment, presenting complaint, catheter details, clinical signs, treatments, and outcome. RESULTS: Most cases resulted from extension set disconnection occurring within approximately 24 hours after catheter placement. In fewer horses, extension set damage was cited as a cause. Common clinical signs included tachycardia, tachypnea, recumbency, muscle fasciculations and agitation, with abnormal behavior including kicking and flank biting. Less commonly, pathological arrhythmias or more severe neurologic signs, including blindness and seizures, were noted. Progression was unpredictable, with some affected horses developing delayed-onset neurologic signs. Mortality was 6/32 (19%), including 2 cases of sudden death and other horses euthanized because of persistent neurologic deficits. Negative outcomes were more common in horses with recorded blindness, sweating or recumbency, but blindness resolved in 5/8 affected horses. CONCLUSIONS AND CLINICAL IMPORTANCE: The prognosis for resolution of clinical signs after air embolism is fair, but permanent neurologic deficits or pathologic cardiac arrhythmias can arise. Unpredictable progression warrants close monitoring. Systematic clinic-based surveillance could provide additional useful information to aid prevention.

PMID- 29460302 TI - Fecal microbiota transplantation in puppies with canine parvovirus infection. AB - BACKGROUND: Diarrhea associated with parvovirus infection is common in dogs. Supportive care is the mainstay of treatment, but recovery may be prolonged and mortality rate can be high. Modification of the intestinal bacterial microbiota has been promising in human and veterinary medicine as an adjunctive treatment of various enteric diseases. OBJECTIVES: To investigate the safety and efficacy of fecal microbiota transplantation (FMT) on the clinical recovery of puppies with acute hemorrhagic diarrhea syndrome. ANIMALS: Sixty-six puppies with parvovirus infection were evaluated at 2 veterinary hospitals. METHODS: Randomized clinical trial. Puppies were randomly distributed into 2 groups: standard treatment (STD) and standard treatment + FMT (STD + FMT). The STD puppies (n = 33) received only treatment with IV fluids and antimicrobials and the STD + FMT puppies (n = 33) received FMT in addition to standard treatment. For FMT, 10 g of feces from a healthy dog diluted in 10 mL of saline were administered rectally 6-12 hours post admission. RESULTS: Among survivors, treatment with FMT was associated with faster resolution of diarrhea (P < .001) and shorter hospitalization time (P = .001; median, 3 days in STD + FMT; median, 6 days in STD) compared to standard treatment. Mortality in STD was 36.4% (12/33) as compared to 21.2% (7/33) in puppies treated with FMT, but there was no statistical difference between groups (P = .174). Polymerase chain reaction indicated that all animals carried canine parvovirus, strain CPV-2b. CONCLUSIONS: Fecal microbiota transplantation in parvovirus-infected puppies was associated with faster resolution of diarrhea. PMID- 29460303 TI - Polycystic ovary syndrome and adverse pregnancy outcomes: Current state of knowledge, challenges and potential implications for practice. AB - Although there is a growing body of literature reporting that pregnancies in women with polycystic ovary syndrome (PCOS) are associated with greater complications than those without PCOS, methodological differences across studies make these results difficult to consolidate. This narrative review outlines potential mechanisms involved in adverse pregnancy outcomes in PCOS and the nature of the complications. It covers limitations of current evidence and future research directions. Future research should include prospective studies with phenotypic stratification of PCOS and matching or consideration of specific PCOS manifestations and risk factors specific to each pregnancy complication. This review also emphasizes the importance of following a healthy lifestyle for women with PCOS and of individualized care according to overall risk factors for pregnancy complications.

AB - Klinefelter syndrome is the most frequent chromosomal abnormality in patients with nonobstructive azoospermia. The development of advanced assisted reproductive techniques, such as testicular sperm extraction and intracytoplasmic sperm injection, has provided the possibility of biological fathering in nonobstructive azoospermic patients with Klinefelter syndrome. We aimed to evaluate our sperm retrieval rate by microdissection testicular sperm extraction and to analyse the intracytoplasmic sperm injection outcomes in these patients. Medical records of 110 nonobstructive azoospermic patients with Klinefelter syndrome were retrospectively reviewed. We found that the sperm retrieval rate by microdissection testicular sperm extraction is lower than published reports on other types of secretory azoospermia. The statistical analyses yielded that age, FSH and testosterone levels as predictive factors for successful sperm retrieval. PMID- 29460305 TI - Photochemical inhibition of Trichophyton rubrum by different compoundings of curcumin. AB - Recently, we had shown that conidia-derived growth of many dermatophytes can be inhibited by curcumin plus exposure to visible light. This method of photo inactivation should be developed further aiming for an option to stop mycelial growth in superficial tinea. Wells of microtitre plates were inoculated with either mycelial or conidial elements collected from 5 strains of Trichophyton rubrum. Then either micellar curcumin or curcumin dissolved with DMSO was added and after 20 min the wells were filled up with Sabouraud broth. Thereafter the assays were irradiated once with visible light (wave length 420 nm, 20 J/cm2 ) and fungal growth was monitored photometrically. Identical effects were measured with conidia and mycelial elements of all 5 T. rubrum strains. Curcumin dissolved with DMSO plus irradiation had a marked dose-dependent inhibitory effect on fungal growth that was almost complete with 5.0 mg/L (P < .01) over a period of 9 days. In contrast, the same procedure with micellar curcumin had no inhibitory effect on growth obtained from conidia or mycelial elements. Mycelial elements of T. rubrum and its conidia are equally sensitive to photochemical inactivation with curcumin and the galenic compounding of curcumin is essential to achieve this photochemical effect. PMID- 29460306 TI - Pathophysiology of axial spondyloarthritis: Consensus and controversies. AB - BACKGROUND: Axial spondyloarthritis (axSpA) is a common inflammatory arthritis of the sacroiliac joints and the spine. The best-known and most studied form of axSpA is ankylosing spondylitis. DESIGN: In this review, we provide a brief overview of the pathophysiology of axSpA. In addition, we performed a quantitative text analysis of reviews on the pathogenesis of axSpA published in the last 10 years to establish the current consensus in various fields of research into the pathogenesis of axSpA. RESULTS: There appears to be broad consensus on genetic risk factors and the involvement of the immune system in the initiation phase of the disease although little consensus was found on which specific immune cells drive disease. Moreover, despite relatively little data available, alterations in the microbiome are commonly thought to be involved in disease. Abnormal bone formation is the most prominent pathogenic factor thought to be involved in disease progression. CONCLUSION: So, although the pathophysiology of axSpA remains incompletely understood, the progress in recent years in several fields of research in axSpA including genetics, diagnosis, imaging and therapeutics, hold great promise for the future. PMID- 29460307 TI - Antibodies to human platelet antigens form a significant proportion of platelet antibodies detected in Indian patients with refractoriness to platelet transfusions. AB - BACKGROUND: The transfusion of platelets is an important therapeutic strategy in bleeding patients with thrombocytopenia. However, some chronically transfused patients fail to achieve the appropriate platelet count increment following transfusion due to the presence of platelet alloantibodies. OBJECTIVES: The aims of this research were to study the prevalence of platelet alloimmunisation and to characterise the platelet-reactive (PR) antibodies in haematology patients refractory to platelet transfusions in an Indian setting. PATIENTS AND METHODS: A total of 80 patients with a prior history of multiple transfusions (minimum of five cellular transfusions) were included in the study if they did not achieve an adequate corrected count increment within 24 h of the platelet transfusion. Patients with non-immunological causes of platelet refractoriness were excluded from the study. The test was performed on a blood sample of 4 mL of Ethylenediaminetetraacetic acid (EDTA) blood sample in which plasma was separated and stored at -80 degrees C and underwent batch testing in PAK-2LE. RESULTS: The overall prevalence of platelet alloimmunisation in our study was 60%. Of the 48 patients who were detected to have platelet antibodies, the combination of anti human leucocyte antigen (HLA) and platelet-specific (PS) antibodies together constituted the majority of 54.2%. The overall prevalence of anti-HLA antibodies was 51.25% and of PS antibodies was 41.25% in the total study population of 80. CONCLUSION: The overall prevalence of PS antibodies in our study was greater than that reported by other groups in India and other countries. This needs to be considered, particularly in the management of patients refractory to platelet transfusions, where HLA-matched platelets constitute current best practice. PMID- 29460308 TI - Parental Depression, Overreactive Parenting, and Early Childhood Externalizing Problems: Moderation by Social Support. AB - This study used a large (N = 519), longitudinal sample of adoptive families to test overreactive parenting as a mediator of associations between parental depressive symptoms and early childhood externalizing, and parents' social support satisfaction as a moderator. Maternal parenting (18 months) mediated the association between maternal depressive symptoms (9 months) and child externalizing problems (27 months). Paternal parenting was not a significant mediator. Unexpectedly, we found a cross-over effect for the moderating role of social support satisfaction, such that partners' social support satisfaction reduced the strength of the association between each parent's own depressive symptoms and overreactive parenting. Results point to the importance of accounting for broader family context in predicting early childhood parenting and child outcomes. PMID- 29460309 TI - Entrapment of LTB protein in alginate nanoparticles protects against Enterotoxigenic Escherichia coli. AB - Vaccine delivery vehicles are just as important in vaccine efficiency. Through the progress in nanotechnology, various nanoparticles have been evaluated as carriers for these substances. Among them, alginate nanoparticles are a good choice because of their biodegradability, biocompatibility, ease of production, etc. In this study, feasibility of alginate nanoparticles (NPs) such as recombinant LTB from Enterotoxigenic Escherichia coli (ETEC) carrier was investigated. To do this, the eltb gene was cloned and expressed in E. coli BL21 (DE3) host cells, and a Ni-NTA column purified the protein. NPs were achieved through ion gelation method in the presence of LTB protein and CaCl2 as the cross Linker and NPs were characterized physicochemically. Balb/C mice groups were immunized with LTB-entrapped NPs or LTB with adjuvant and immunogenicity was assessed by evaluating IgG titer. Finally, the neutralization of antibodies was evaluated by GM1 binding and loop assays. LTB protein was expressed and efficiently entrapped into the alginate NPs. The size of NPs was less than 50 nm, and entrapment efficiency was 80%. Western blotting showed maintenance of the molecular weight and antigenicity of the released protein from NPs. Administration of LTB-entrapped NPs stimulated antibody responses in immunized mice. Immunization induced protection against LT toxin of ETEC in ileal loops and inhibits enterotoxin binding to GM1-gangliosides. Alginate NPs are also appropriate vehicle for antigen delivery purpose. Moreover because of their astonishing properties, they have the potential to serve as an adjuvant. PMID- 29460310 TI - LC-MS based metabolic and metabonomic studies of Panax ginseng. AB - INTRODUCTION: Panax ginseng has received much attention as a valuable health supplement with medicinal potential. Its chemical diversity and multiple pharmacological properties call for comprehensive methods to better understand the effects of ginseng and ginsenosides. Liquid chromatography-mass spectrometry (LC-MS) based metabonomic approaches just fit the purpose. OBJECTIVE: Aims to give a review of recent progress on LC-MS based pharmacokinetic, metabolic, and phytochemical metabolomic studies of ginseng, and metabonomic studies of ginseng intervention effects. METHODS: The review has four sections: the first section discusses metabolic studies of ginsenosides based on LC-MS, the second focuses on ginsenoside-drug interactions and pharmacokinetic interaction between herb compounds based on LC-MS, the third is phytochemical metabolomic studies of ginseng based on LC-MS, and the fourth deals with metabonomic studies of ginseng intervention effects based on LC-MS. RESULTS: LC-MS based metabonomic research on ginseng include analysis of single ginsenoside and total ginsenosides. The theory of multi-components and multi-targeted mechanisms helps to explain ginseng effects. CONCLUSION: LC-MS based metabonomics is a promising way to comprehensively assess ginseng. It is valuable for quality control and mechanism studies of ginseng.

AB - Engineered cytochrome P450s are emerging as powerful synthetic tools due to their ability catalyze non-native metallocarbenoid and -nitrenoid insertion reactions. P450-mediated cyclopropanation has garnered particular interest due to the high selectivity demonstrated by engineered scaffolds and their application towards the synthesis of therapeutic agents. We previously reported that mutation of a conserved, first-shell heme-ligating Cys to Ser led to significant improvements in cyclopropanation activity in a model enzyme, P450BM3h . Here, we demonstrate that mutation of a ubiquitously conserved second-shell Phe (F393) to His or Ala, provides complementary increases in the P450 heme reduction potential and conversion to cyclopropanation products when compared to first-shell Cys to Ser mutations. Furthermore, we show that these mutations confer improved non-natural catalysis in 4 diverse P450 scaffolds. PMID- 29460312 TI - Eigenstate versus Zeeman-based approaches to the solid effect. AB - The solid effect is one of the simplest and most effective mechanisms for dynamic nuclear polarization. It involves the exchange of polarization between one electron and one nuclear spin coupled via the hyperfine interaction. Even for such a small spin system, the theoretical understanding is complicated by the contact with the lattice and the microwave irradiation. Both being weak, they can be treated within perturbation theory. In this work, we analyze the two most popular perturbation schemes: the Zeeman and the eigenstate-based approaches, which differ in the way the hyperfine interaction is treated. For both schemes, we derive from first principles an effective Liouville equation that describes the density matrix of the spin system; we then study numerically the behavior of the nuclear polarization for several values of the hyperfine coupling. In general, we obtain that the Zeeman-based approach underestimates the value of the nuclear polarization. By performing a projection onto the diagonal part of the spin-system density matrix, we are able to understand the origin of the discrepancy, which is due to the presence of parasite leakage transitions appearing whenever the Zeeman basis is employed.

PMID- 29460314 TI - Brooding as moderator of depressive symptoms after a work accident: A longitudinal study. AB - This study analyzes the relationship between having experienced a work accident and developing depressive symptoms six months later, considering the subjective severity of accidents, the use of both positive and negative religious coping strategies, and brooding as predictors variables. Fifty seven women and 187 men were evaluated during the month following their accident (T1) and six months later (T2). The results show that after controlling for initial depressive symptoms, all predictors showed a statistically significant relationship with depression at six months, including the interaction between brooding and subjective severity of accident. Forty nine percent of resilient participants exhibited low symptoms at T1 and T2, 22% of recovered individuals showed high symptoms at T1 and low symptoms afterwards, 20% of depressive individuals had high symptoms at T1 and T2, and 8% exhibited high symptoms only at T2. High severity, brooding and religious coping at T1 differentiated those who exhibited stable symptoms from those who were resilient. Resilience was specifically predicted with a negative coefficient by the interaction of brooding with subjective severity of accident. We conclude that brooding is a variable that moderates the relationship between subjective severity of accident and the development and maintenance of depressive symptoms. Subjective severity of accident, brooding and negative religious coping are risk factors, while positive religious coping is not a sufficient protection factor. PMID- 29460315 TI - Sealed osteons in animals and humans: low prevalence and lack of relationship with age. AB - Sealed osteons are unusual variants of secondary osteons that have received little attention, especially in non-human bones. Sealed osteons are characterized by central canals that are plugged with bone tissue. As with other variants of secondary osteons (e.g. drifting, dumbbell, multi-canal), understanding how and why sealed osteons form can shed light on the mechanisms that regulate normal bone remodeling and how this process can be perturbed with aging and some diseases. In a recent microscopic evaluation of human tibiae obtained after traumatic amputations, 4-5% of the osteons were sealed. It is suggested that this high prevalence reflects occasional localized microscopic ischemia from normal osteonal remodeling; hence sealed osteons are implicated in human skeletal fragility. Therefore, osteon prevalence would be expected to correlate with the bone remodeling seen with aging; for example, showing positive relationships between sealed osteons and the population density of typical secondary osteons (OPD). We evaluated the prevalence of partially sealed (80-99% sealed) and fully sealed osteons with respect to age and variations in OPD in 10 adult human femora (34-71 years) and in various non-human appendicular bones of mature animals that were not of advanced age, including deer calcanei, equine radii and equine third metacarpals. An additional sample of 10 bilateral human femora with unilateral non-cemented total hip replacements (F,+HR) and non-implanted contralateral femora (F,-HR) were evaluated (10 patients; 52-94 years). In non-human bones, sealed + partially sealed osteons were rare (~0.1%) even when having relatively high OPD. When considering sealed + partially sealed osteons in femora from patients without any HR, results showed that 1.6% of the osteons were sealed or partially sealed, which was much lower than anticipated, but this is 10- to 20 fold more than in any of the non-human bones. Additionally, in all bones, sealed + partially sealed osteons were significantly smaller than typical secondary osteons (mean diameters: 125 vs. 272 MUm; P < 0.005). In the patients with HR, the percentage of sealed + partially sealed osteons: (i) did not correlate with age, (ii) showed no significant difference between F,-HR and F,+HR (1.9 vs. 2.1%; P = 0.2), and (iii) was positively correlated with OPD (r = 0.67, P = 0.001), which differs from the very weak or lack of correlations in the non-human bones and the other human femur sample. The lack of an age-related relationship, in addition to the very low prevalence of sealed + partially sealed osteons are inconsistent with the idea that they contribute to reduced bone quality seen in aging humans. The small size of sealed and partially sealed osteons, regardless of species affiliation, suggests that they represent closing cones at the termini of some osteons. Available evidence suggests that osteons of primates might have a greater capacity for branching that is associated with closing cones, which might explain the 10-20 times higher prevalence of sealed + partially sealed osteons in the human bones examined in this study. PMID- 29460316 TI - Light and scanning electron microscopy of the olfactory mucosa in the rufous sengi (Elephantulus rufescens). AB - Sengis are eutherian insectivores belonging to superorder Afrotheria, a recently defined clade of mammals that diverged from other placentals over 100 million years ago. In this study, a histological and ultrastructural analysis was carried out on the olfactory mucosa (OM) of the rufous sengi (Elephantulus rufescens) and the data were compared with those reported earlier in the dog (Canis familiaris) and the sheep (Ovis aries), whose dietary lifestyles are carnivorous and herbivorous, respectively. Qualitatively, the microstructure of the sengi's OM was basically similar to that of the other eutherian mammals except for differences in the pattern of cilia projection from the dendritic knobs of the olfactory receptor neurons (ORNs) and distribution of Bowman's glands within the lamina propria of the OM. On morphometry, significant differences (p < .05) were recorded with respect to olfactory epithelial (OE) thickness between the sengi (65.4 +/- 2.6 MUm) and the other species. ORN packing density and cilia number/ORN knob varied markedly only between the sengi (73.8 +/- 5.4 mm-2 * 103 and 15 +/- 4, respectively) and the sheep. No remarkable differences were noted in regard to ORN bundle diameters between sengis (62.7 +/- 12.5 MUm) and the other species. The observed differences in OM structural refinement may be attributed to olfactory function demand levels related to feeding lifestyles and ecology. Myrmecophagous insectivory, social monogamy, absentee maternal care and exposed sheltering habits are behavioural features that may warrant substantial OM modification in sengis. PMID- 29460317 TI - Effects of aldehyde products of lipid oxidation on the color stability and metmyoglobin reducing ability of bovine Longissimus muscle. AB - Lipid oxidation and metmyoglobin (MMb) reduction are popular issues in meat color research. This study evaluated the effects of aldehyde products, particularly 4 hydroxy-2-nonenal (HNE) and hexenal, of lipid oxidation on the oxymyoglobin stability, mitochondrial membrane permeability, MMb reduction ability, electron transport chain-mediated MMb reduction, and nicotinamide adenine dinucleotide reduced form (NADH)-dependent MMb reductase activity of bovine Longissimus muscle. The results indicated that HNE and hexenal accelerate the oxidation rate of oxymyoglobin, significantly increase the permeability of the mitochondrial membrane, and inhibit electron transport chain-mediated MMb reduction. However, HNE and hexenal were found to exert no effect on the activity of NADH-dependent MMb reductase. Thus, the aldehyde products of lipid oxidation could damage the microstructure of mitochondria and inhibit mitochondria-mediated MMb reduction, which is disadvantageous in terms of the color stability of fresh bovine Longissimus muscle. PMID- 29460318 TI - Antagonistic effects of growing season and autumn temperatures on the timing of leaf coloration in winter deciduous trees. AB - Autumn phenology remains a relatively neglected aspect in climate change research, which hinders an accurate assessment of the global carbon cycle and its sensitivity to climate change. Leaf coloration, a key indicator of the growing season end, is thought to be triggered mainly by high or low temperature and drought. However, how the control of leaf coloration is split between temperature and drought is not known for many species. Moreover, whether growing season and autumn temperatures interact in influencing the timing of leaf coloration is not clear. Here, we revealed major climate drivers of leaf coloration dates and their interactions using 154 phenological datasets for four winter deciduous tree species at 89 stations, and the corresponding daily mean/minimum air temperature and precipitation data across China's temperate zone from 1981 to 2012. Results show that temperature is more decisive than drought in causing leaf coloration, and the growing season mean temperature plays a more important role than the autumn mean minimum temperature. Higher growing season temperature and lower autumn minimum temperature would induce earlier leaf coloration date. Moreover, the mean temperature over the growing season correlates positively with the autumn minimum temperature. This implies that growing season mean temperature may offset the requirement of autumn minimum temperature in triggering leaf coloration. Our findings deepen the understanding of leaf coloration mechanisms in winter deciduous trees and suggest that leaf life-span control depended on growing season mean temperature and autumn low temperature control and their interaction are major environmental cues. In the context of climate change, whether leaf coloration date advances or is delayed may depend on intensity of the offset effect of growing season temperature on autumn low temperature.

AB - To examine the validity of popular smartphone accelerometer applications and a consumer activity wristband compared to a widely used research accelerometer while assessing the impact of the phone's position on the accuracy of step detection. Twenty volunteers from 2 different age groups (Group A: 18-25 years, n = 10; Group B 45-70 years, n = 10) were equipped with 3 iPhone SE smartphones (placed in pants pocket, shoulder bag, and backpack), 1 Samsung Galaxy S6 Edge (pants pocket), 1 Garmin Vivofit 2 wristband, and 2 ActiGraph wGTX+ devices (worn at wrist and hip) while walking on a treadmill (1.6, 3.2, 4.8, and 6.0 km/h) and completing a walking course. All smartphones included 6 accelerometer applications. Video observation was used as gold standard. Validity was evaluated by comparing each device with the gold standard using mean absolute percentage errors (MAPE). The MAPE of the iPhone SE (all positions) and the Garmin Vivofit was small (<3) for treadmill walking >=3.2 km/h and for free walking. The Samsung Galaxy and hip-worn ActiGraph showed small MAPE only for treadmill walking at 4.8 and 6.0 km/h and for free walking. The wrist-worn ActiGraph showed high MAPE (17 47) for all walking conditions. The iPhone SE and the Garmin Vivofit 2 are accurate tools for step counting in different age groups and during various walking conditions, even during slow walking. The phone's position does not impact the accuracy of step detection, which substantially improves the versatility for physical activity assessment in clinical and research settings.

AB - RATIONAL, AIMS, AND OBJECTIVES: Registries are a powerful tool to assess specific performance measurements and quality of care in acute coronary syndromes (ACSs). In Portugal, ProACS is a nationwide registry of ACS that has been active for the past 15 years, and our objective was to assess specific quality indicators for the treatment of ACS. METHODS: Descriptive analysis of data from ProACS registry in specific quality indicators previously defined by international scientific societies. RESULTS: A total of 45,141 patients were included since 2002, 43.5% with ST-segment elevation myocardial infarction. In ST-segment elevation myocardial infarction, reperfusion rates, particularly by primary angioplasty, have increased dramatically with 85% being submitted to any form of reperfusion presently. In-hospital time delays are, however, suboptimal, particularly in patients admitted first to hospitals without catheterization facilities. For non ST elevation ACS, invasive strategy also showed important improvements, with more than 80% of patients being submitted to catheterization. Although there was also improvement in the use of guideline recommended medication, particularly statins, it is also suboptimal, requiring additional specific interventions. CONCLUSION: The quality of care of ACS improved dramatically in the last 15 years in Portugal, with major improvements in hospital mortality. It is, however, suboptimal in specific points that have been identified and that require additional measures. PMID- 29460321 TI - Factors associated with delayed infant immunization in a nationally representative cohort study. AB - BACKGROUND: Many children in developed countries do not receive recommended vaccines on time. However, knowledge about factors related to timeliness remains limited. Quantifying the relative impact of parental attitudes compared with socio-demographic factors for delayed immunization would inform policy responses. METHODS: Participants in the nationally representative Longitudinal Study of Australian Children were matched with their vaccination histories in the Australian Childhood Immunisation Register (N = 4,121). Information about the children and their families were collected in face-to-face interviews in 2003 2004. We considered whether children had completed the primary course for each recommended antigen due by 6 months old. Children were categorized as either fully immunized, delayed, or totally non-immunized. The outcome was examined using logistic regression. Population attributable fractions were estimated for key predictors. RESULTS: Delayed immunization was significantly associated with indicators of social disadvantage as well as parental disagreement with immunization. Attributable fractions for delayed immunization included lone motherhood (3.8%; 95% confidence interval CI [0.8, 6.7]), larger family size (39.5%; 95% CI [31.2, 46.8]), residential mobility (3.3%; 95% CI [0.1, 6.5]), lack of private hospital insurance (9.4%; 95% CI [0.7, 17.3]), a medical condition in the child (2.0%; 95% CI [0.2, 3.9]), and parental disagreement with immunization (2.1%; 95% CI [0.3, 3.9]). CONCLUSIONS: Parental attitudes accounted for a relatively small percentage of delayed infant immunization. In contrast, many children who did not receive vaccines on time were characterized by social disadvantage, especially larger family size. Researchers and policy-makers should consider how to make timely immunization easier for busy parents.

AB - In nature, proteins serve as media for long-distance electron transfer (ET) to carry out redox reactions in distant compartments. This ET occurs either by a single-step superexchange or through a multi-step charge hopping process, which uses side chains of amino acids as stepping stones. In this study we demonstrate that Phe can act as a relay amino acid for long-distance electron hole transfer through peptides. The considerably increased susceptibility of the aromatic ring to oxidation is caused by the lone pairs of neighbouring amide carbonyl groups, which stabilise the Phe radical cation. This neighbouring-amide-group effect helps improve understanding of the mechanism of extracellular electron transfer through conductive protein filaments (pili) of anaerobic bacteria during mineral respiration. PMID- 29460323 TI - Clinical guidelines for prevention and management of preterm birth: a systematic review. AB - BACKGROUND: Clinical practice guidelines (CPG) endorse multiple strategies to prevent or manage preterm birth (PTB). OBJECTIVES: To summarise CPG recommendations for PTB and identify areas of international consensus. SEARCH STRATEGY: In May 2017 we searched for all CPG relevant to PTB without language restrictions. SELECTION CRITERIA: CPG were eligible if the following criteria were met: (1) the guideline was published or current from June 2013; (2) the guideline recommended practices for the prevention or management of PTB relevant to our prespecified clinical questions for screening, medications or surgery and other interventions; (3) publications on methods of guideline development for eligible CPG were included to enable quality assessment. DATA COLLECTION AND ANALYSIS: Two authors classified CPG recommendations relevant to prespecified clinical questions. When more than 70% of CPGs reporting on a topic recommended or rejected an intervention, we regarded this as consensus. We summarised recommendations in tables. MAIN RESULTS: We identified 49 guidelines from 16 guideline developers. We found consensus for several clinical practices: cervical length screening for high-risk women; short-term tocolysis; steroids for fetal lung maturation; and magnesium sulphate for fetal neuroprotection. We found discrepant recommendations for progesterone and fibronectin. No guideline identified an effective strategy for women with multiple pregnancy. CONCLUSIONS: We identified interventions for which there is an international consensus on benefit for PTB. Systematic reviews of CPG using standardised methodology will help avoid duplication and target scarce resources for guideline developers globally. TWEETABLE ABSTRACT: International clinical guidelines agree on the benefits and harmful effects of several important interventions to prevent preterm birth. PMID- 29460324 TI - Peri-prostatic adipose tissue: the metabolic microenvironment of prostate cancer. AB - Emerging data have linked certain features of clinical prostate cancer (PCa) to obesity and, more specifically, increased adiposity. Whereas the large number of clinical studies and meta-analyses that have explored the associations between PCa and obesity have shown considerable variability, particularly in relation to prostate cancer risk, there is an accumulating weight of evidence consistently linking obesity to greater aggressiveness of disease. In probing this association mechanistically, it has been posited that peri-prostatic adipose tissue (PPAT), a significant component of the prostate microenvironment, may be a critical source of fatty acids and other mitogens and thereby influences PCa pathogenesis and progression. Notably, several recent studies have identified secreted factors from both PPAT and PCa that potentially mediate the two-way communication between these intimately linked tissues. In the present review, we summarize the available literature regarding the relationship between PPAT and PCa, including the potential biological mediators of that relationship, and explore emerging areas of interest for future research endeavours.

AB - The estrogenic and anti-estrogenic effects of butylparaben (BuPB), butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT) and propyl gallate (PG) were evaluated for individual compounds as well as for binary mixtures, using an estrogen-dependent reporter gene assay in T47D-Kbluc breast cancer cells and an estrogen-dependent proliferation assay in MCF-7 breast cancer cells. In terms of estrogenicity the potency of the selected compounds increased from BHA < PG < BuPB in the luciferase assay (with BHT showing no significant estrogenic activity), while in the proliferation assay the following order was observed: BHT < BHA < BuPB (with PG showing no significant estrogenic activity). Non-monotonic dose-response curves were obtained for BuPB (in both assays) and PG (in the luciferase assay), respectively. In the presence of estradiol, a significant anti estrogenic activity was observed in both cell lines for PG, BuPB and BHA, while BHT showed weak anti-estrogenic activity only in T47D-Kbluc cells. The evaluation of binary mixtures confirmed the endocrine disruptive potential of the compounds, their individual potency being correlated with that of the mixtures. All mixtures were able to reduce the estradiol-induced luminescence or cell proliferation, an effect that was accurately predicted by the dose addition mathematical model, suggesting the same (or at least partially overlapping) modes of action for the tested compounds. The results of the present study emphasize the importance of a cumulative risk assessment of endocrine disruptors.

AB - OBJECTIVES: Accurate sex estimation is an essential step for the reconstruction of the biological profile of human remains. Earlier studies have shown that elements of the human permanent dentition are sexually dimorphic. The aims of this study are to determine the degree of sexual dimorphism in the dental tissue volumes and surface areas of mandibular canines and to explore its potential for reliable sex determination. METHOD: The teeth included in this study (n = 69) were selected from anthropological collections from Spain, South Africa and Sudan. In all cases, the sex of the individuals was known. The teeth were scanned and three-dimensional (3D) measurements (volumes and surfaces areas) were obtained. Finally, a dsicriminant function analysis was applied. RESULTS: Our results showed that sexual dimorphism in canine size is due to males having greater amounts of dentine, whereas enamel volume does not contribute significantly to overall tooth size dimorphism. Classification accuracy of the multivariable equations tested on slightly worn teeth ranged from 78 to 90.2% for the crossvalidation, and from 71.43 to 84.62% for the hold-out sample validation. When all functions were applied together, the sex was correctly assigned 92.30% of the time. CONCLUSIONS: Our results suggest that the 3D variables from mandibular canine dental tissues are useful for sex determination as they present a high degree of dimorphism. The results obtained show the importance of 3D dental tissue measurements as a methodology in sex determination, which application should be considered as a supplemental method to others.

AB - BACKGROUND: Despite multiple dilatation procedures, benign esophageal strictures (BES) remain a recurring cause of morbidity and mortality in dogs and cats. OBJECTIVE: Investigate the use of an indwelling Balloon Dilatation esophagostomy tube (B-Tube) for treatment of BES in dogs and cats. ANIMALS: Nine dogs and 3 cats. METHODS: Animals with BES were recruited for our prospective study. Endoscopic and fluoroscopic evaluation of the esophagus and balloon dilatation were performed under general anesthesia, followed by placement of an indwelling B Tube. The animals' owners performed twice daily at-home inflations for approximately 6 weeks. Repeat endoscopy was performed before B-Tube removal. Animals were reevaluated for changes in modified dysphagia score (MDS) after B Tube removal. RESULTS: The B-Tube management was relatively well tolerated and effective in maintaining dilatation of a BES while in place. These animals underwent a median of 2 anesthetic episodes and were monitored for a median of 472 days (range, 358-1736 days). The mean MDS before treatment was 3.1 +/- 0.5/4.0 and final follow-up MDS were significantly (P < .0001) improved at 0.36 +/- 0.65/4.0. Eleven of 12 animals (91.7%) had improved MDS at the end of the follow-up period, with 8/12 (66.7%) having an MDS of 0/4, 2/12 (16.7%) an MDS of 1/4, and 1/12 (8.3%) an MDS of 2/4. One dog died. CONCLUSIONS AND CLINICAL IMPORTANCE: The B-Tube offers an effective, and more economical method, and often decreased anesthetic time to repeated balloon dilatation procedures for the treatment of BES in dogs and cats. PMID- 29460331 TI - Clinical and Neuroimaging Findings in Thalamic Territory Infarctions: A Review. AB - The thalamus is a part of the diencephalon, containing numerous connections between the forebrain and subcortical structures. It serves an important function as a relay center between the cerebral cortex and the subcortical regions, particularly with sensory information. The thalamus also plays a major role in regulating arousal and the levels of awareness. Distinct vascular distribution of the thalamus give rises to different syndromic presentation of thalamic nuclei infarcts. The clinical records and available imaging studies of patients with confirmed thalamic territory infarcts on magnetic resonance imaging (MRI) at the University Hospital of Rochester were reviewed and analyzed. This analysis was then used to provide an effective summary of thalamic vascular anatomy, the clinical symptoms, and syndromes associated with strokes in the affected territories. Specifically, we review the syndromes associated with classic vascular territories, including the anterior, paramedian, inferolateral, and posterior thalamic nuclei, that are supplied by the polar (tuberothalamic), paramedian, inferolateral (thalamogeniculate), and posterior choroidal arteries, respectively. In addition, we will also review the variant thalamic territories and associated infarction syndromes of the anteromedian, central, and posterolateral territories. This review article is aimed to better the clinical and radiologic understanding as well as the diagnosis of classic and variant thalamic territory infarcts. This article will also briefly touch on the recovery of function after thalamic infarcts. PMID- 29460332 TI - Vitamin D levels in acne vulgaris patients treated with oral isotretinoin. AB - BACKGROUND/OBJECTIVES: Acne vulgaris is a common inflammatory skin disease. Vitamin D deficiency plays a role in many inflammatory skin diseases. It may play a role in pathogenesis of acne vulgaris. This study aimed to assess serum levels of 25 hydroxy vitamin D in patients with acne vulgaris before and after treatment with isotretinoin and its relation with acne vulgaris severity. METHODS: Ninety patients with acne vulgaris and 60 age-sex matched healthy subject as controls have been recruited in this study. Patients were treated with 0.75 mg/kg/d isotretinoin for 3 months. Serum level of 25 hydroxy vitamin D has been measured at baseline and after treatment. RESULTS: Serum levels of 25 hydroxy vitamin D were significantly higher in patients with acne vulgaris than healthy controls (P = .001). There was a significant inverse relation between level of 25 hydroxy vitamin D and severity of acne vulgaris before treatment (P = .001). Serum levels of 25 hydroxy vitamin D were significantly increased after isotretinoin treatment in patients with acne vulgaris (P = .001). CONCLUSION: This study concluded that vitamin D may play a potential role in pathogenesis of acne vulgaris or acne vulgaris may have a negative effect on vitamin D synthesis. Further studies are needed to confirm these potential relations. PMID- 29460333 TI - Comparison of diagnostic accuracy of laparoscopic 3 mm and 5 mm cup biopsies to wedge biopsies of canine livers. AB - BACKGROUND: Diagnostic accuracy of the 3 mm laparoscopic cup biopsy forceps for collection of tissue samples from canine livers is unproven. HYPOTHESES/OBJECTIVES: Compare sample surface area and portal triad count between 3 mm and 5 mm laparoscopic cup biopsies and compare the histologic diagnosis obtained by each instrument to a standard necropsy wedge. The hypothesis was that more portal triads and greater sample surface area would be found with the 5 mm samples and the laparoscopic instruments would not have significantly different levels of agreement with necropsy wedge diagnosis. ANIMALS: Twenty-one client owned dogs undergoing necropsy. METHODS: Prospective ex vivo study. Three samples (3 mm, 5 mm, and wedge) were taken of 2 different hepatic divisions within 24 hours of death. Morphologic diagnosis, World Small Animal Veterinary Association histologic features, surface area, and portal triad numbers were compared among the 3 samples. RESULTS: There were significantly more portal triads (mean 21.4 versus 13.8; P < .0001) and a higher surface area (20.3 mm2 versus 11.5 mm2 ; P < .0001) in the 5 mm samples compared to 3 mm samples. Kappa coefficients and percent agreement for histologic diagnosis as compared to the wedge biopsy were not significantly different between the 2 instrument sizes (kappa = 0.383 and 0.436, respectively; 67% and 69%, respectively). CONCLUSIONS AND CLINICAL IMPORTANCE: Despite yielding smaller sample sizes, the 3 mm laparoscopic cup biopsy has a similar level of histologic diagnostic accuracy to the 5 mm instrument. PMID- 29460334 TI - Variation of renal function over time is associated with major bleeding in patients treated with direct oral anticoagulants for atrial fibrillation. AB - : Essential In patients on treatment with direct anticoagulants (DOACs) variation of renal function is common. The effect of variations of renal function over time on major bleeding is not well defined. Variation of renal function over time is an independent predictor of major bleeding. Identifying conditions associated with variation of renal function may increase safety of DOACs. SUMMARY: Background Chronic kidney disease is a risk factor for major bleeding in patients with atrial fibrillation (AF) treated with warfarin. Objective To assess the effect of variations in renal function over time on the risk of major bleeding during treatment with direct oral anticoagulants (DOACs) in patients with non valvular AF. Methods Consecutive AF patients were prospectively followed after they had received the first DOAC prescription. Estimated glomerular filtration rate (eGFR) was periodically assessed, and the incidence of major bleeding was recorded. A joint survival model was used to estimate the association between variation in eGFR and the risk of major bleeding. Results During a mean follow-up of 575 days, 44 major bleeds occurred in 449 patients (6.1% per patient-year). eGFR over time was inversely and independently associated with the risk of major bleeding; every 1 mL min-1 absolute decrease in eGFR was associated with a 2% increase in the risk of major bleeding (hazard ratio [HR] 1.02, 95% confidence interval [CI] 1.01-1.04). A similar effect of the variation in eGFR over time was observed on the risk of clinically relevant non-major bleeding (HR 1.02, 95% CI 1.01-1.03). Deterioration of renal function leading to a change in eGFR staging was associated with an increase in the risk of major bleeding (HR 2.43, 95% CI 1.33-4.45). Conclusions Variation in renal function over time is associated with the risk of major bleeding in AF patients treated with DOACs in real life. Identification of intervening clinical conditions associated with variation in renal function is essential to reduce the risk of major bleeding and to make DOAC treatment more safe. PMID- 29460335 TI - Liposomal Treatment of Cancer Cells Modulates Uptake Pathway of Polymeric Nanoparticles by Altering Membrane Stiffness. AB - Nanomedicines can be taken up by cells via nonspecific and dynamin-dependent (energy-dependent) clathrin and caveolae-mediated endocytosis. While significant effort has focused on targeting pathway-specific transporters, the role of nanobiophysics in the cell lipid bilayer nanoparticle uptake pathway remains largely unexplored. In this study, it is demonstrated that stiffness of lipid bilayer is a key determinant of uptake of liposomes by mammalian cells. Dynamin mediated endocytosis (DME) of liposomes is found to correlate with its phase behavior, with transition toward solid phase promoting DME, and transition toward fluidic phase resulting in dynamin-independent endocytosis. Since liposomes can transfer lipids to cell membrane, it is sought to engineer the biophysical properties of the membrane of breast epithelial tumor cells (MD-MBA-231) by treatment with phosphatidylcholine liposomes, and elucidate its effect on the uptake of polymeric nanoparticles. Analysis of the giant plasma membrane vesicles derived from treated cells using flicker spectroscopy reveals that liposome treatment alters membrane stiffness and DME of nanoparticles. Since liposomes have a history of use in drug delivery, localized priming of tumors with liposomes may present a hitherto unexploited means of targeting tumors based on biophysical interactions. PMID- 29460336 TI - Emollient product design: objective measurements of formulation structure, texture and performance, and subjective assessments of user acceptability. AB - BACKGROUND: The choice of prescribed emollients is usually based on cost and patient preference. Differences in formulations can affect user acceptability. AIM: To compare the physical performance, user acceptability and various product design features of two emollient gels that are prescribed in the UK and alleged to be therapeutically interchangeable because their formulations are described as having the same contents of oily ingredients. RESULTS: We found that here are in fact significant measurable differences between the structure and performance of the two formulations, which materially affect their user acceptability. These differences are attributed to the use of different types of gelling agents and other ingredients of differing grades/quality and concentrations, and probably due to the formulations being made by different manufacturing processes. We also identified other product design features that are important to user appeal, including the type of container in which the formulations are presented, the type of dispensing devices provided, and the nature and form of the supplied user instructions. CONCLUSION: Patients and prescribers should be aware that there can be important differences in performance and user appeal between emollients, even between products that, superficially, may appear to be very similar. These important performance aspects should be characterized for new emollient introductions to encourage better informed product selection. PMID- 29460337 TI - A pilot study to evaluate the effectiveness of an individualized and cognitive behavioural communication intervention for informal carers of people with dementia: The Talking Sense programme. AB - BACKGROUND: People with dementia and family carers often experience difficulties communicating together. These difficulties are considered to contribute significantly to the depression, anxiety and negative feelings such as guilt often reported by dementia family carers. AIMS: To develop and contribute to the theory and evidence base for single-component, psychosocial interventions that address these difficulties by evaluating the effectiveness of the Talking Sense programme which was designed to reflect existing best evidence. METHODS & PROCEDURES: Talking Sense was delivered as an individualized, one to one, cognitive behavioural approach for developing knowledge, skills, thinking and behaviour of dementia family carers in managing communication difficulties. In this study, a randomized controlled trial compared 27 carers who completed three one-to-one individualized sessions using Talking Sense with 25 carers who received a single, knowledge-only, control discussion. OUTCOMES & RESULTS: There were no significant differences for the primary outcome measure of carer anxiety and depression as well as carer quality of life and general self-efficacy. Statistically significant results suggested carers receiving the Talking Sense intervention had fewer communication difficulties happening (p = 0.046) and felt more valued by their relatives (p = 0.046). A score close to significance (p = 0.052) suggested they perceived their relatives to be more communicatively competent. CONCLUSIONS & IMPLICATIONS: The intervention and research design were shown to be effective with low attrition and high adherence to treatment. A non significant finding for the primary outcome measure does not support the potential for this intervention to effect carer anxiety and depression. The potential for perceived change in the person with dementia, with statistically fewer communication difficulties happening and the carer feeling more valued by their relative, was the most significant finding from this programme of research. Recommendations for further research are made. PMID- 29460339 TI - Protective effect of ghrelin on testicular damages caused by chronic hypoxia in rats: A histopathological study. AB - Hypoxia can lead to changes in the blood flow, nutrition and oxygenation of male germ cells and results in fertility reduction through the increase in oxidative stress. This study aims to evaluate the effect of ghrelin on testicular damage induced by hypoxia in rats. In this experimental study, 24 male rats were randomly divided into four groups: control, hypoxia, hypoxia + ghrelin and ghrelin. Animals in the control and ghrelin groups were kept in room air with 21% oxygen. The animals in the groups of hypoxia and hypoxia + ghrelin were subjected to 11% oxygen for 14 consecutive days in the hypoxia chamber. At the end of the study, the testes were removed and histological changes, as well as the apoptotic index, were investigated. Morphometrical analysis showed that hypoxia caused a significant decrease in the seminiferous tubules diameter, the germinal epithelium thickness and main Johnson's score compared to the control group (p < .05). In addition, statistical comparisons revealed a significant increase in the apoptotic index in the hypoxia group (p < .05). Administration of ghrelin + hypoxia improved the parameters mentioned above (p < .05). The results of this study indicated that ghrelin decreases the testicular damages caused by hypoxia in the rats by antioxidative activity. PMID- 29460338 TI - MDSCs drive the process of endometriosis by enhancing angiogenesis and are a new potential therapeutic target. AB - Endometriosis affects women of reproductive age via unclear immunological mechanism(s). Myeloid-derived suppressor cells (MDSCs) are a heterogeneous group of myeloid cells with potent immunosuppressive and angiogenic properties. Here, we found MDSCs significantly increased in the peripheral blood of patients with endometriosis and in the peritoneal cavity of a mouse model of surgically induced endometriosis. Majority of MDSCs were granulocytic, produced ROS, and arginase, and suppressed T-cell proliferation. Depletion of MDSCs by antiGr-1 antibody dramatically suppressed development of endometrial lesions in mice. The chemokines CXCL1, 2, and 5 were expressed at sites of lesion while MDSCs expressed CXCR-2. These CXC-chemokines promoted MDSC migration toward endometriotic implants both in vitro and in vivo. Also, CXCR2-deficient mice show significantly decreased MDSC induction, endometrial lesions, and angiogenesis. Importantly, adoptive transfer of MDSCs into CXCR2-KO mice restored endometriotic growth and angiogenesis. Together, this study demonstrates that MDSCs play a role in the pathogenesis of endometriosis and identifies a novel CXC-chemokine and receptor for the recruitment of MDSCs, thereby providing a potential target for endometriosis treatment. PMID- 29460340 TI - Evaluation of In Vitro alpha-Amylase and alpha-Glucosidase Inhibitory Potentials of 14 Medicinal Plants Constituted in Thai Folk Antidiabetic Formularies. AB - The sporadic increase in the occurrence and prevalence of diabetes mellitus have compelled and vigorous search for alternative anti-diabetic therapeutic approach from medicinal plants and its bioactive. One of the major approach employed is the reduction of gastrointestinal glucose levels through the inhibition of carbohydrate digesting enzymes notably alpha-amylase and alpha-glucosidase. In this study, the ethanol extracts of 14 selected plants from Mor Porn's recipe were screened for their alpha-amylase and alpha-glucosidase inhibitory activity. The ethanolic extract from the stem of Vitex glabrata displayed the highest percentage inhibitory activity of 84.98 +/- 0.59 and 84.71 +/- 1.51 against alpha glucosidase and alpha-amylase enzymes, respectively. Chemical investigation of the active extract of V. glabrata indicated that pentacyclic triterpenes were the major compounds responsible for the activity. The result obtained from this study suggests the potential use of V. glabrata as an alternative natural source for the treatment of diabetes mellitus. PMID- 29460341 TI - Continuing rise of Type 2 diabetes incidence in children and young people in the UK. AB - AIMS: To estimate the incidence of Type 2 diabetes in children aged <17 years, compare this with similar data 10 years ago, and characterize clinical features at diagnosis in the UK and Republic of Ireland. METHODS: Using the British Paediatric Surveillance Unit reporting framework, cases of Type 2 diabetes diagnosed in children aged <17 years between 1 April 2015 and 30 April 2016 were reported each month. RESULTS: A total of 106 cases were reported, giving a UK incidence of 0.72/100 000 (95% CI 0.58-0.88). Children from ethnic minorities had significantly higher incidence compared with white children (0.44/100 000) with rates of 2.92/100 000 and 1.67/100 000, in Asian and BACBB (black/African/Caribbean/black British) children respectively. Sixty-seven percent were girls and 81% had a family history of Type 2 diabetes. The mean BMI sd score at diagnosis was 2.89 (2.88, girls; 2.92, boys); 81% were obese. Children of Asian ethnicity had a significantly lower BMI sd score compared with white children (P<0.001). There was a trend in increased incidence from 2005 to 2015, with a rate ratio of 1.35 (95% CI 0.99-1.84), although this was not statistically significant (P=0.062). There was statistical evidence of increased incidence among girls (P=0.03) and children of South-Asian ethnicity (P=0.01) when comparing the 2005 and 2015 surveys. CONCLUSIONS: Type 2 diabetes remains far less common than Type 1 diabetes in childhood in the UK, but the number of cases continues to rise, with significantly increased incidence among girls and South-Asian children over a decade. Female gender, family history, non-white ethnicity and obesity were found to be strongly associated with the condition.

AB - The terminal-selective, remote C(sp3 )-H alkylation of alkenes was achieved by a relay process combining NiH-catalyzed hydrometalation, chain walking, and alkylation. This method enables the construction of unfunctionalized C(sp3 ) C(sp3 ) bonds under mild conditions from two simple feedstock chemicals, namely olefins and alkyl halides. The practical value of this transformation is further demonstrated by the large-scale and regioconvergent alkylation of isomeric mixtures of olefins at low catalyst loadings.

Due to scarce clinical and experimental data on the pathogenicity of Candida auris, the aim of this study was to evaluate and compare the virulence of two rare clinically relevant species, C. auris and Candida haemulonii with Candida glabrata and Candida albicans in an immunocompetent murine model of disseminated infection. Immunocompetent ICR female mice were infected with three inoculum sizes (1 * 105 , 1 * 106 and 1 * 107 CFU/mouse) of two C. auris strains and one isolate of C. haemulonii, C. glabrata and C. albicans. Tissue burden on days 5 and 10 postchallenge and mortality rate were used as virulence markers. A high virulence was found for C. albicans, followed by C. auris, C. glabrata and C. haemulonii, respectively. Candida albicans showed high virulence with a medium survival time of 9.5 days for mice infected with 1 * 107 CFU/mouse. For inocula at 1 * 106 and 1 * 107 CFU/mouse, there were significant differences in fungal burden at day 10 between C. albicans, C. auris and C. glabrata isolates compared with C. haemulonii (P < .0001). Overall, no significant differences between C. albicans with C. auris and C. glabrata were observed in mice infected with three different inocula (P > .05). In general, the highest fungal load of all isolates was detected in kidney followed by spleen, liver and lung tested with three different inocula on the two different experimental days. Histopathological examination revealed the abundant presence of yeast cells with pseudohyphae for C. albicans and only yeast cells for C. auris, C. glabrata and C. haemulonii, in all the kidney tissue samples. In conclusion, C. albicans is a highly virulent opportunistic fungus, as the clinical and experimental data demonstrate, and also our results demonstrate a low virulence of C. haemulonii in immunocompetent animals. Altogether, this study highlights the pathogenic potential of C. auris. PMID- 29460347 TI - Human skin in vivo has a higher skin barrier function than porcine skin ex vivo comprehensive Raman microscopic study of the stratum corneum. AB - Porcine skin is widely used as a human skin model in dermatology. For both, porcine stratum corneum (SC) ex vivo and human SC in vivo, the hydrogen bonding states of water, the secondary and tertiary structures of keratin, the natural moisturizing factor (NMF) concentrations and the intercellular lipids' (ICL) lateral organization are investigated depth-dependently using confocal Raman microscopy. The SC depth profiles show that porcine SC ex vivo is characterized by lower hydrogen bonding states of water (10%-30% SC depth), lower NMF concentration in the whole SC, more beta-sheet form of keratin (10%-90% SC depth), more folded tertiary keratin structures (30%-70% SC depth) and higher hexagonal lateral packing order of ICL (10%-50% SC depth) compared to human SC in vivo. The results clearly show a higher value of skin barrier function of human SC in vivo than of porcine SC ex vivo. Thus, the human SC in vivo is less permeable for lipophilic and hydrophilic substances than porcine SC ex vivo. Considering the porcine SC as an ex vivo model of human SC in vivo, these findings should be taken into consideration. PMID- 29460349 TI - Adolescent Brain Development: Implications for Understanding Risk and Resilience Processes Through Neuroimaging Research. AB - This special section focuses on research that utilizes neuroimaging methods to examine the impact of social relationships and socioemotional development on adolescent brain function. Studies include novel neuroimaging methods that further our understanding of adolescent brain development. This special section has a particular focus on how study findings add to our understanding of risk and resilience. In this introduction to the special section, we discuss the role of neuroimaging in developmental science and provide a brief review of neuroimaging methods. We present key themes that are covered in the special section articles including: (1) emerging methods in developmental neuroscience, (2) emotion cognition interaction, and (3) the role of social relationships in brain function. We conclude our introduction with future directions for integrating developmental neuroscience into the study of adolescence, and highlight key points from the special section's commentaries which include information on the landmark Adolescent Brain Cognitive Development (ABCD) study. PMID- 29460348 TI - Positive and Negative Affect and Adolescent Adjustment: Moderation Effects of Prefrontal Functioning. AB - We examined whether cognitive control moderates the effects of emotion on adolescent internalizing and externalizing symptomatology in a longitudinal study of 138 adolescents. Self-reported positive affect (PA) and negative affect and behavioral and neural indicators of cognitive control, indexed by performance and prefrontal hemodynamic response during a cognitive interference task, were collected at Time 1. Self-reported internalizing and externalizing symptomatology were collected at Time 1 and Time 2 (1 year later). Results indicated that higher PA predicted decreases in externalizing symptomatology, but only for adolescents with poor neural cognitive control. No moderation effects were found for behavioral cognitive control. Findings imply the beneficial effects of PA on the development of externalizing problems among adolescents with poor prefrontal functioning. PMID- 29460351 TI - Dyadic Neural Similarity During Stress in Mother-Child Dyads. AB - Shared psychological processes between individuals occur most between a mother and her child because the mother-child bond is one of the closest forms of human attachment, in which a mother and her child are essentially wired to connect. We recruited mother-child pairs (Ndyad = 19; adolescent: Mage = 13.74, 11 males; mothers: Mage = 44.26), who each completed an fMRI scan. We examined dyadic neural representational similarity as adolescents completed a stress task and mothers observed their child's performance during the same task. On average, mothers and their children did not show similar neural patterns during stress. However, neural similarity varied depending on family connectedness, such that only dyads reporting high family connectedness showed similar neural profiles. Importantly, increased neural similarity was associated with reduced stress in youth, suggesting that shared neural profiles in mother-child dyads enhance adolescents' psychological well-being. PMID- 29460350 TI - Pathways to Youth Behavior: The Role of Genetic, Neural, and Behavioral Markers. AB - Neural and temperamental mechanisms through which a genetic risk marker in the gamma-amino butyric acid alpha2 receptor subunit (GABRA2) impacts adolescent functioning were investigated. Participants (N = 80; 29 female) completed an emotional word task during functional magnetic resonance imaging. Behavioral control, negative emotionality, and resiliency temperament constructs were assessed. Externalizing and internalizing problems were the outcomes. Those with the GABRA2 minor allele had reduced activation to positive words in the angular gyrus, middle temporal gyrus, and cerebellum, and to negative words in frontal, parietal, and occipital cortices. Reduced activation in the angular gyrus predicted greater negative emotionality and, in turn, elevated externalizing problems. Reduced activation in the inferior parietal cortex predicted greater resiliency and, in turn, low externalizing problems. PMID- 29460352 TI - The Adolescent Brain Cognitive Development Study. PMID- 29460353 TI - A Ripe Time for Adolescent Research. PMID- 29460354 TI - Longitudinal Associations Between Family Aggression, Externalizing Behavior, and the Structure and Function of the Amygdala. AB - Using longitudinal data from 21 adolescents, we assessed family aggression (via mother, father, and youth report) in early adolescence, externalizing behavior in mid-adolescence, and magnetic resonance imaging (MRI) data in late adolescence. Amygdalae were manually traced, and used as seed regions for resting state analyses. Both family aggression and subsequent externalizing behavior predicted larger right amygdala volumes and stronger amygdala-frontolimbic/salience network connectivity and weaker amygdala-posterior cingulate connectivity. Externalizing behavior in mid-adolescence mediated associations between family aggression in early adolescence and resting state connectivity between the amygdala and the subgenual anterior cingulate cortex, medial prefrontal cortex, orbitofrontal cortex, and posterior cingulate cortex in late adolescence. Family adversity and adolescent behavior problems may share common neural correlates. PMID- 29460356 TI - Broadening the Impact of Developmental Neuroscience on the Study of Adolescence. AB - Having been a significance source of the renewed interested in the adolescent period, developmental neuroscience now needs to build upon its achievements to date and expand in several areas in order to broaden its impact upon the field. Addressing both typical and atypical development, examining the interaction between brain development and the social environment, studying change over time, and including attention to population diversity can help to produce a truly integrative science of adolescent development. The papers in the special section provide nice examples of how developmental neuroscience can make such expansions and continue to contribute to the field in the years to come. PMID- 29460355 TI - Do Hostile School Environments Promote Social Deviance by Shaping Neural Responses to Social Exclusion? AB - The present study examined adolescents' neural responses to social exclusion as a mediator of past exposure to a hostile school environment (HSE) and later social deviance, and whether family connectedness buffered these associations. Participants (166 Mexican-origin adolescents, 54.4% female) reported on their HSE exposure and family connectedness across Grades 9-11. Six months later, neural responses to social exclusion were measured. Finally, social deviance was self reported in Grades 9 and 12. The HSE-social deviance link was mediated by greater reactivity to social deviance in subgenual anterior cingulate cortex, a region from the social pain network also implicated in social susceptibility. However, youths with stronger family bonds were protected from this neurobiologically mediated path. These findings suggest a complex interplay of risk and protective factors that impact adolescent behavior through the brain. PMID- 29460357 TI - Neural Correlates of Risky Sex and Response Inhibition in High-Risk Adolescents. AB - Adolescence is a neurodevelopmental period of heightened sexual risk taking. Neuroimaging can help elucidate crucial neurocognitive mechanisms underlying adolescent sexual risk behavior, yet few empirical studies have investigated this neural link. To address this gap in the literature, we examined the association between neurocognitive function during response inhibition-a known correlate of risk behaviors-and frequency of intercourse without a condom among adolescents. We examined the correlation between condom use and fMRI-based Stroop response in a large ethnically diverse sample of high-risk adolescents (n = 171). Partially replicating previous literature, sexual risk was positively correlated with blood oxygen-level-dependent (BOLD) activation in the middle frontal gyrus during response inhibition, highlighting the relevance of this region during risky sexual decision making within this age group. PMID- 29460358 TI - Role of Social Environmental Protective Factors on Anxiety and Depressive Symptoms Among Midwestern Homeless Youth. AB - We employ a social stress framework, which examines the influence of multiple stressors (e.g., physical abuse, foster care placement) on an individual's ability to function (e.g., mental well-being), to longitudinally examine the effects of stressful life events on mental health and the role of the social environment in this process among 150 homeless youth. Results revealed that numerous stressors, such as physical abuse and running away from home more frequently, were associated with greater depressive symptoms and elevated anxiety. Having mentors and family and friends from home that youth can rely on resulted in more positive social support, which subsequently lowered the risk for depressive symptoms and anxiety at wave 2. PMID- 29460359 TI - Connecting Theory and Methods in Adolescent Brain Research. AB - Networks are often implicated in theories of adolescent brain development, but they are not regularly examined in empirical studies. The aim of this article is to address this disconnect between theory and quantitative methodology, using the dual systems model of adolescent decision making as a prototype. After reviewing the key task-related connectivity methods that have been applied in the adolescent neuroimaging literature (seed-based correlations, psychophysiological interactions, and dynamic causal modeling), a novel connectivity method is introduced (extended unified structural equation modeling). The potential of this method for understanding adolescent brain development is showcased with a simulation study: It creates person-specific networks that have direct and time lagged connections that can be modulated by behavior. PMID- 29460360 TI - A Three-Year Emotional Intelligence Intervention to Reduce Adolescent Aggression: The Mediating Role of Unpleasant Affectivity. AB - Adolescents' aggressive behavior is a growing social problem with important implications for psychosocial adjustment. The teaching of emotional skills has an important impact on reducing aggression in schools. However, little scientific evidence has shown the explanatory mechanism through which this training reduces aggression during adolescence. This article aims to provide evidence for the effectiveness of a 3-year longitudinal intervention among adolescents in nine Spanish schools. A total of 476 adolescents participated. Results showed a reduction in physical and verbal aggression in Time 2 through the reduction in negative affect, anger, and hostile feelings, compared with an active control group. The training seems to be crucial for dealing with the emotional and cognitive components of aggression and, thus, their behavioral manifestations. PMID- 29460361 TI - Attentional Bias for Academic Stressors and Classroom Climate Predict Adolescents' Grades and Socioemotional Functioning. AB - Using a dot-probe detection task, this longitudinal study investigated whether adolescents show an attentional bias for academic stressors at the beginning of the school year (T1), and if such allocation of attention interacts with classroom climate (CC) to predict grades and socioemotional functioning at the end of the term (T2). Among 133 eighth-graders, the majority showed a perceptual bias toward academic threats. Regression analyses indicated that a greater bias at T1 predicted lower grades and more socioemotional problems at T2, and that CC moderated these relationships. Students perceiving low CC and displaying greater attentional bias reported lower grades and more socioemotional problems. Teachers may promote a positive CC to prevent the negative effects of a biased attention on youths' school adjustment. PMID- 29460363 TI - Neural Substrates of Counterfactual Emotions After Risky Decisions in Late Adolescents and Young Adults. AB - Adolescents' neural substrates of emotional reactions to the consequences of risky decisions are poorly understood. In this functional magnetic resonance imaging study, 30 late adolescents and 30 young adults made risky and neutral decisions in social scenarios and received valenced outcomes. Negative outcomes in risky decisions eliciting regret, as compared with negative outcomes in neutral decisions eliciting disappointment, activated executive control (orbitofrontal cortex) and self-relevance regions (middle temporal gyrus [MTG], posterior cingulate cortex, and precuneus) for both age groups. Young adults showed more activation than adolescents in regret and disappointment as compared with relief and elation conditions in the avoidance (insula), action monitoring (inferior frontal gyrus, pre-SMA, and caudate), and social-cognition regions (superior temporal sulcus and MTG). These late socio-emotional developments may pave the way for more adaptive decision-making behavior in social contexts. PMID- 29460364 TI - Longitudinal Transmission of Conflict Management Styles Across Inter-Parental and Adolescent Relationships. AB - This study longitudinally investigated transmission of conflict management styles across inter-parental, adolescent-parent, adolescent-friend, and adolescent partner relationships. During four waves, 799 middle-to-late adolescents (Mage-t1 = 15.80; 54% boys) and their parents completed the Conflict Resolution Style Inventory. Cross-lagged path analyses indicated transmission of adolescent conflict management styles in relationships with parents to relationships with friends and romantic partners: Positive problem solving and conflict engagement utilized by adolescents in conflicts with parents were significantly, positively related to, respectively, adolescent positive problem solving and conflict engagement in relationships with friends 1 year later and relationships with partners 2 years later. Thus, the study showed that the way adolescents manage conflicts with parents predicts how they handle conflicts later in relationships outside the family. PMID- 29460362 TI - Prefrontal Cortical Response to Negative Social Words Links Social Risk to Depressive Symptoms in Adolescence. AB - Research suggests that altered emotion processing may be one important pathway linking social risk factors and depressive symptoms. We examined the extent to which neural response to negatively valenced social information might help to account for the relationship between social risk and depressive symptoms in youth. Forty-nine youth were scanned while identifying the emotional valence of words that connoted social status. They also completed questionnaires assessing self-reported social risk factors and depressive symptoms. Mediation analysis revealed that reduced dorsolateral prefrontal cortex activity in response to negative social status words explained the positive association between social risk and depressive symptoms. These findings suggest that social risk factors present during adolescence may contribute to depressive symptoms by influencing the neural substrates of emotion processing. PMID- 29460365 TI - A Capsule-Type Microrobot with Pick-and-Drop Motion for Targeted Drug and Cell Delivery. AB - A capsule-type microrobot exhibits "pick-and-drop" (P&D) motion to hold a particle within a confined volume and transports it via a corkscrewing motion. The P&D motion is possible because the capsule-type microrobot has two parts: a plunger and a cap. The fabricated microrobots are wirelessly controlled by a magnetic manipulator. Drugs or cells can be encapsulated in the container of the capsule-type microrobot by the P&D motion or attached to the surface of the cap, which can be used as a supporting structure. Therefore, the capsule-type microrobot can deliver suspended or adherent cells. The drug or cells are minimally exposed or not completely exposed to the surrounding fluid and do not experience shear force when encapsulated in the container. As a proof-of-concept, secure transportation of microparticles in the confined volume of the capsule via P&D motion is demonstrated. In addition, the cap is used as a scaffold for neuronal cell culture on a rat brain slice to demonstrate its biocompatibility and feasibility for targeted cell delivery. The proposed capsule-type microrobot is suitable for diverse applications, as it protects the encapsulated materials. PMID- 29460366 TI - Ejection fraction as a statistical index of left ventricular systolic function: the first full allometric scrutiny of its appropriateness and accuracy. AB - Left ventricular ejection fraction (EF) is a ratio that is deemed to accurately normalize stroke volume (SV) to end-diastolic volume (EDV). Ratios are now well recognized for not normalizing the numerator, in this case SV, consistently for the denominator, EDV. We aimed to provide the first allometric-based scrutiny of the conventional assumptions that underpin the EF ratio. We allometrically modelled untransformed SV and EDV measurements from 112 preclinical heart failure patients in the Multi-Ethnic Study of Atherosclerosis (MESA), and 864 chronic heart failure patients in the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist (TOPCAT) study. An information-theoretic approach was adopted to assess the relative quality of twelve candidate models for normalizing SV to EDV. None of the conventional underlying assumptions for accurate ratio normalization, for example an allometric exponent ~1, were upheld for EF. A two-parameter power function with normal, heteroscedastic error was the best model for scaling SV to EDV in both samples. The allometric exponent (95% confidence interval) was 0.776 (0.682 to 0.869) in MESA, and 0.860 (0.857 to 0.864) in TOPCAT. EF was inversely correlated with EDV in MESA (r = -0.67, 95% CI: -0.76 to -0.55) and TOPCAT (r = -0.41, 95% CI: -0.46 to -0.35). Consequently, for fundamental statistical reasons, EF was biased low for people with generally larger EDVs, and vice versa. For the first time, we have demonstrated that EF is an inaccurate statistic for scaling SV to EDV, leading to potential biased inferences for research and individual patients.

PMID- 29460368 TI - Immediate, short-, and long-term changes in tracheal stent diameter, length, and positioning after placement in dogs with tracheal collapse syndrome. AB - BACKGROUND: Intraluminal tracheal stenting is a minimally invasive procedure shown to have variable degrees of success in managing clinical signs associated with tracheal collapse syndrome (CTCS) in dogs. OBJECTIVES: Identify immediate post-stent changes in tracheal diameter, determine the extent of stent migration, and stent shortening after stent placement in the immediate-, short-, and long term periods, and evaluate inter-observer reliability of radiographic measurements. ANIMALS: Fifty client-owned dogs. METHODS: Retrospective study in which medical records were reviewed in dogs with CTCS treated with an intraluminal tracheal stent. Data collected included signalment, location, and type of collapse, stent diameter and length, and post-stent placement radiographic follow-up times. Radiographs were used to obtain pre-stent tracheal measurements and post-stent placement measurements. RESULTS: Immediate mean percentage change was 5.14%, 5.49%, and 21.64% for cervical, thoracic inlet, and intra-thoracic tracheal diameters, respectively. Ultimate mean follow-up time was 446 days, with mean percentage change of 2.55%, 15.09%, and 8.65% for cervical, thoracic inlet, and intra-thoracic tracheal diameters, respectively. Initial mean stent length was 26.72% higher than nominal length and ultimate long-term tracheal mean stent shortening was only 9.90%. No significant stent migration was identified in the immediate, short-, or long-term periods. Good inter-observer agreement of radiographic measurements was found among observers of variable experience level. CONCLUSIONS AND CLINICAL IMPORTANCE: Use of an intraluminal tracheal stent for CTCS is associated with minimal stent shortening with no clinically relevant stent migration after fluoroscopic placement. Precise stent sizing and placement techniques likely play important roles in avoiding these reported complications. PMID- 29460369 TI - Drought timing and local climate determine the sensitivity of eastern temperate forests to drought. AB - Projected changes in temperature and drought regime are likely to reduce carbon (C) storage in forests, thereby amplifying rates of climate change. While such reductions are often presumed to be greatest in semi-arid forests that experience widespread tree mortality, the consequences of drought may also be important in temperate mesic forests of Eastern North America (ENA) if tree growth is significantly curtailed by drought. Investigations of the environmental conditions that determine drought sensitivity are critically needed to accurately predict ecosystem feedbacks to climate change. We matched site factors with the growth responses to drought of 10,753 trees across mesic forests of ENA, representing 24 species and 346 stands, to determine the broad-scale drivers of drought sensitivity for the dominant trees in ENA. Here we show that two factors the timing of drought, and the atmospheric demand for water (i.e., local potential evapotranspiration; PET)-are stronger drivers of drought sensitivity than soil and stand characteristics. Drought-induced reductions in tree growth were greatest when the droughts occurred during early-season peaks in radial growth, especially for trees growing in the warmest, driest regions (i.e., highest PET). Further, mean species trait values (rooting depth and psi50 ) were poor predictors of drought sensitivity, as intraspecific variation in sensitivity was equal to or greater than interspecific variation in 17 of 24 species. From a general circulation model ensemble, we find that future increases in early-season PET may exacerbate these effects, and potentially offset gains in C uptake and storage in ENA owing to other global change factors. PMID- 29460370 TI - The association between team-level social capital and individual-level work engagement: Differences between subtypes of social capital and the impact of intra-team agreement. AB - The study explored the association between team-level social capital and individual-level work engagement. Questionnaire data were collected from six companies in the dairy industry. Seven hundred seventy-two participants divided into 65 teams were included. In confirmatory factor analyses, we found a superior model fit to a four dimensional model of social capital: bonding social capital, bridging social capital and two types of linking social capital. The results showed a positive association between all subtypes of social capital at the team level and work engagement at the individual level. However, this association only remained significant for linking social capital in relation the workplace as a whole when we adjusted for psychosocial working conditions. The level of intra team agreement in social capital score did not moderate the association between social capital and work engagement. In conclusion, the results provide further support for previous findings suggesting a positive association between social capital and work engagement. They add to the existing knowledge by suggesting that linking social capital in relation to the workplace is the most important explanatory variable for work engagement, thus emphasizing the need to distinguish between subtypes of social capital in research and practice.

PMID- 29460373 TI - Examining regional variability in work ethic within Mexico: Individual difference or shared value. AB - Despite the acceptance of work ethic as an important individual difference, little research has examined the extent to which work ethic may reflect shared environmental or socio-economic factors. This research addresses this concern by examining the influence of geographic proximity on the work ethic experienced by 254 employees from Mexico, working in 11 different cities in the Northern, Central and Southern regions of the country. Using a sequence of complementary analyses to assess the main source of variance on seven dimensions of work ethic, our results indicate that work ethic is most appropriately considered at the individual level. PMID- 29460372 TI - Effects of a rice diet and phytase addition on growth performance, tissue weights, phosphorus and nitrogen retention, and on liver threonine dehydrogenase, malic enzyme and fatty acid synthase activities in broiler chicks. AB - This experiment was conducted to clarify the nutritional functions of rice and phytase addition for broiler chicks. Thirty-six 7-day-old male chicks (ROSS 308 strain) were assigned to one of the four treatment groups: corn- or rice-based diet groups and each diet with added phytase (2000 phytase units/kg diet) groups (corn + P or rice + P groups). The non-phytate phosphorus (npP) content in the diets with added phytase was approximately half of the requirement. Body weight gain and feed intake in the rice group was significantly higher than those in the corn group. Breast and thigh muscle weights and nitrogen retention in the rice group were significantly higher than that in the corn group. Although the efficiency of phosphorus retention (%) in the corn + P group was significantly higher than that in the corn group, no significant difference was observed between the rice and rice + P groups. Liver threonine dehydrogenase activity in the corn group was significantly higher than in the other three groups. These results indicate that rice is superior to corn as a starter diet in broiler chicks, and that phytase action in the rice-based diet was less than that in the corn-based diet. PMID- 29460374 TI - Del Nido cardioplegia for minimally invasive aortic valve replacement. AB - BACKGROUND: We analyzed the impact and safety of del Nido Cardioplegia (DNC) in patients undergoing minimally invasive aortic valve replacement (MIAVR). METHODS: We analyzed all isolated MIAVR replacements from 5/2013-6/2015 excluding re operative patients. The approach was a hemi-median sternotomy in all patients. Patients were divided into two cohorts, those who received 4:1 crystalloid:blood DNC solution and those in whom standard 1:4 Buckberg-based cardioplegia (WBC) was used. One-to-one propensity case matching of DNC to WBC was performed based on standard risk factors and differences between groups were analyzed using chi square and non-parametric methods. RESULTS: MIAVR was performed in 181 patients; DNC was used in 59 and WBC in 122. Case matching resulted in 59 patients per cohort. DNC was associated with reduced re-dosing (5/59 (8.5%) versus 39/59 (61.0%), P < 0.001) and less total cardioplegia volume (1290 +/- 347 mL vs 2284 +/- 828 mL, P < 0.001). Antegrade cardioplegia alone was used in 89.8% (53/59) of DNC patients versus 33.9% (20/59) of WBC patients (P < 0.001). Median bypass and aortic cross-clamp times were similar. Clinical outcomes were similar with respect to post-operative hematocrit, transfusion requirements, need for inotropic/pressor support, duration of intensive care unit stay, re-intubation, length of stay, new onset atrial fibrillation, and mortality. CONCLUSIONS: Del Nido cardioplegia usage during MIAVR minimized re-dosing and the need for retrograde delivery. Patient safety was not compromised with this technique in this group of low-risk patients undergoing MIAVR. PMID- 29460376 TI - Large Negative Differential Resistance and Rectification from a Donor-sigma Acceptor Molecule in the Presence of Dissimilar Electrodes. AB - A multifunctional spin quantum device obtained by sandwiching 11-mercaptoundeca 2,4,8,10-tetraenenitrile, a donor-sigma-acceptor molecule, between gold and iron electrodes is proposed. The device can act as a spin rectifier at lower bias and also exhibits negative differential resistance (NDR) after attaining a bias of 1.3 V. The rectification feature is quite prominent in the spin-up channel, with an appreciable rectification ratio of 68, whereas the NDR indicator, that is, the peak to valley ratio (~10) of the current-voltage characteristics after 1.3 V, is also quite significant. To understand the origin of this in silico observation, nonequilibrium green's function based DFT calculations have been performed. Analyses reveal that both properties originate from the bias-independent energy offset between the frontier orbitals and electrode Fermi levels, popularly known as Fermi-level pinning. More precisely, rectification results from the Fermi level pinning of the HOMO and LUMO with the gold and iron electrodes, respectively; the Fermi-level pinning forces a HOMO-LUMO crossover that helps to explain the origin of the NDR. PMID- 29460375 TI - Periodontal education and assessment in the undergraduate dental curriculum-A questionnaire-based survey in European countries. AB - OBJECTIVES: This survey aimed to evaluate whether periodontal education and assessment in undergraduate dental curricula amongst the member countries of the European Federation of Periodontology (EFP) follow the competency-based curricular guidelines and recommendations developed by the Association for Dental Education in Europe. MATERIALS AND METHODS: A multiple-choice questionnaire was emailed to 244 dental institutes amongst the 24 EFP member countries between November 2014 and July 2015. RESULTS: Data were received from 16 (66.7%) EFP member countries. Out of 117 responding dental institutes, 76 (64.95%) were included as valid responders. In most of the institutes (86.3%), a minimum set of competencies in periodontology was taken into account when constructing their dental education programmes. Out of 76 responders, 98.1% included lecture-based, 74.1% case-based and 57.1% problem-based teaching in their periodontal curricula, whilst a minority (15.9%) also used other methods. A similar pattern was also seen in the time allocation for these four educational methods, that is, the highest proportion (51.8%) was dedicated to lecture-based teaching and only a small proportion (5.7%) to other methods. Periodontal competencies and skills were most frequently assessed by clinical grading on clinic, multiple-choice examination (written examination) and oral examination, whereas competency tests and self-assessment were rarely used. Only in 11 (14.5%) cases, access flap procedures were performed by students. CONCLUSION: Great diversity in teaching methodology amongst the surveyed schools was demonstrated, and thus, to harmonise undergraduate periodontal education and assessment across Europe, a minimum set of recommendations could be developed and disseminated by the EFP.

PMID- 29460378 TI - Bone mineral density and body composition in children with congenital adrenal hyperplasia. AB - OBJECTIVE: Children with congenital adrenal hyperplasia (CAH) are exposed to fluctuating cortisol and androgen levels. The effects these hormonal states have on bone mineral density (BMD) and body composition are not well studied. The study's objective was to compare BMD and body composition, including visceral adipose tissue (VAT) and Android:Gynoid (A:G) ratio, in children with CAH vs healthy age-matched, sex-matched and BMI-matched controls. DESIGN: Total body BMD (TBMD) Z-scores were adjusted for height-for-age Z-scores (TBMDHAZ). Hydrocortisone dose (mg/m2/d) was averaged over the past year. Bone age Z-scores were used as a surrogate for long-term androgen exposure in cases. Statistical analyses comparing cases and controls accounted for matched groups using mixed linear models. PATIENTS: Forty-two cases with CAH (average age 12.3 years [SE 3]; 17 males) and 101 controls underwent a dual-energy X-ray absorptiometry scan. RESULTS: Children with CAH had lower TBMD (0.81 vs 1.27, P = .003) and TBMDHAZ Z scores (-0.51 vs -0.01, P = .001) than controls. In CAH cases, TBMD and TBMDHAZ Z scores were positively correlated with bone age Z-scores (r = .63, P < .0001; r = .51, P = .001, respectively) but were not associated with HC dose. VAT and the A:G ratio did not differ significantly between children with CAH and controls and neither was associated with HC dose.VAT was not associated with bone age Z-score. CONCLUSION: Lower BMD was observed in CAH cases compared with controls although no differences in body composition were identified. Among CAH cases, increased chronic androgen exposure, as measured by bone age Z-scores, was associated with higher BMD but was not associated with VAT. PMID- 29460379 TI - Five-year long-term clinical outcome after bariatric metabolic surgery: A multi ethnic Asian population in Singapore. AB - Bariatric surgery is an effective treatment for morbid obesity and its metabolic related comorbidities; type 2 diabetes, hypertension and hyperlipidaemia.1 However, the literature is scarce regarding the long-term outcome after bariatric surgery, especially among multi-ethnic Asian populations. Considering the growing number of bariatric metabolic surgeries in Asia, we have attempted to provide a regional perspective on 5-year long-term clinical outcomes post bariatric surgery in Singapore. Between 2010 and 2016, all bariatric operative cases were included, and these comprised: laparoscopic sleeve gastrectomy (LSG), 393; laparoscopic Roux-En-Y gastric bypass (RYGB), 125; laparoscopic mini-gastric bypass (MGB), 43. The primary outcome measure was the percentage of excess weight loss (% EWL) at 6 months, 1, 2, 3, 4 and 5 years, with % remission of type 2 diabetes mellitus (T2DM) at 1 year following LSG (49.7%, 61.2%, 56.1%, 47.8%, 40.8% and 47.3%; 82.2%), RYGB (60.2%, 62.1%, 57.6%, 50.1%, 48.7% and 47.7%; 86.9%) and MGB (58%, 68.1%, 62.7%, 66.2%, 64.0%, 65.2%; 71.9%). In conclusion, MGB and RYGB showed the greatest % EWL at 5 years and are recommended for moderate T2DM. LSG is an effective bariatric operation with a high % EWL up to 2 years, and a high remission rate of mild T2DM. The remission rate of T2DM was equally high in all 3 surgical groups, independent of ethnic differences.

AB - The scarcity of precious metals has led to the development of sustainable strategies for metal-catalyzed cross-coupling reactions. The establishment of new catalytic methods using iron is attractive owing to the low cost, abundance, ready availability, and very low toxicity of iron. In the last few years, sustainable methods for iron-catalyzed cross-couplings have entered the critical area of pharmaceutical research. Most notably, iron is one of the very few metals that have been successfully field-tested as highly effective base-metal catalysts in practical, kilogram-scale industrial cross-couplings. In this Minireview, we critically discuss the strategic benefits of using iron catalysts as green and sustainable alternatives to precious metals in cross-coupling applications for the synthesis of pharmaceuticals. The Minireview provides an essential introduction to the fundamental aspects of practical iron catalysis, highlights areas for improvement, and identifies new fields to be explored.

AB - This study utilized actor-partner interdependence modeling to examine the bidirectional effects of younger (Mage = 18 months) and older siblings (Mage = 48 months) on later empathy development in a large (n = 452 families), diverse (42% immigrant) Canadian sample. Controlling for parenting, demographic characteristics, sibling relationship quality, and within-child stability in empathic concern, both younger and older siblings' observed empathic concern uniquely predicted relative increases in the other's empathy over a period of 18 months. The strength of the partner effects did not differ by birth order. Sex composition moderated the younger sibling partner effect, whereas age gap moderated the older sibling partner effect. This study highlights the important role that siblings play in enhancing the development of care and concern for others. PMID- 29460382 TI - An algorithm for predicting Robin sequence from fetal MRI. AB - BACKGROUND: Infants with Robin sequence (RS) may present with airway compromise at delivery. Prenatal diagnosis would improve preparation and postnatal care. The purpose of this study was to devise a predictive algorithm for RS based on fetal magnetic resonance imaging (MRI). METHODS: Retrospective case-control study including fetal MRIs from 2002 to 2017. Inclusion criteria were (1) MRI of adequate quality, (2) live-born infant, and (3) postnatal evaluation. Subjects were grouped on the basis of postnatal diagnosis: (1) RS (micrognathia, glossoptosis, airway obstruction), (2) micrognathia without airway obstruction ("micrognathia"), (3) cleft lip and palate ("CLP"), and (4) gestational age matched controls. A series of possible predictive variables were assessed on MRI. Receiver operator curves were applied to identify cut-off values, and a multivariable algorithm was developed. RESULTS: A total of 162 subjects with mean gestational age at MRI of 25.6 +/- 4.9 weeks were included: RS, n = 27 (17%); micrognathia, n = 35 (22%); CLP, n = 46 (28%); control, n = 54 (33%). Three variables were independent predictors of RS: (1) Veau I/II cleft palate (OR = 38.8), (2) tongue shape index (>80%; OR = 8.7), and (3) inferior facial angle (<48 degrees ; OR = 14.5). CONCLUSION: MRI findings of cleft palate, TSI >80% and IFA <48 degrees indicate a 98% probability of RS, whereas a lack of all 3 features denotes a likelihood of 1%.

AB - RATIONALE, AIMS AND OBJECTIVES: Interrupted time series analysis (ITSA) is an evaluation methodology in which a single treatment unit's outcome is studied serially over time and the intervention is expected to "interrupt" the level and/or trend of that outcome. The internal validity is strengthened considerably when the treated unit is contrasted with a comparable control group. In this paper, we introduce a robustness check based on permutation tests to further improve causal inference. METHOD: We evaluate the effect of California's Proposition 99 for reducing cigarette sales by iteratively casting each nontreated state into the role of "treated," creating a comparable control group using the ITSAMATCH package in Stata, and then evaluating treatment effects using ITSA regression. If statistically significant "treatment effects" are estimated for pseudotreated states, then any significant changes in the outcome of the actual treatment unit (California) cannot be attributed to the intervention. We perform these analyses setting the cutpoint significance level to P > .40 for identifying balanced matches (the highest threshold possible for which controls could still be found for California) and use the difference in differences of trends as the treatment effect estimator. RESULTS: Only California attained a statistically significant treatment effect, strengthening confidence in the conclusion that Proposition 99 reduced cigarette sales. CONCLUSIONS: The proposed permutation testing framework provides an additional robustness check to either support or refute a treatment effect identified in for the true treated unit in ITSA. Given its value and ease of implementation, this framework should be considered as a standard robustness test in all multiple group interrupted time series analyses. PMID- 29460384 TI - Quantum-rotor-induced polarization. AB - Quantum-rotor-induced polarization is closely related to para-hydrogen-induced polarization. In both cases, the hyperpolarized spin order derives from rotational interaction and the Pauli principle by which the symmetry of the rotational ground state dictates the symmetry of the associated nuclear spin state. In quantum-rotor-induced polarization, there may be several spin states associated with the rotational ground state, and the hyperpolarization is typically generated by hetero-nuclear cross-relaxation. This review discusses preconditions for quantum-rotor-induced polarization for both the 1-dimensional methyl rotor and the asymmetric rotor H217 O@C60 , that is, a single water molecule encapsulated in fullerene C60 . Experimental results are presented for both rotors. PMID- 29460386 TI - Amino acid racemization and its relation to geochronology and archaeometry.

PMID- 29460387 TI - Optimizing Water Exchange Rates and Rotational Mobility for High-Relaxivity of a Novel Gd-DO3A Derivative Complex Conjugated to Inulin as Macromolecular Contrast Agents for MRI. AB - Thanks to the understanding of the relationships between the residence lifetime tauM of the coordinated water molecules to macrocyclic Gd-complexes and the rotational mobility tauR of these structures, and according to the theory for paramagnetic relaxation, it is now possible to design macromolecular contrast agents with enhanced relaxivities by optimizing these two parameters through ligand structural modification. We succeeded in accelerating the water exchange rate by inducing steric compression around the water binding site, and by removing the amide function from the DOTA-AA ligand [1,4,7,10 tetraazacyclododecane-1,4,7,10-tetraacetic acid mono(p-aminoanilide)] (L) previously designed. This new ligand 10[2(1-oxo-1-p-propylthioureidophenylpropyl] 1,4,7,10-tetraazacyclodecane-1,4,7-tetraacetic acid (L1 ) was then covalently conjugated to API [O-(aminopropyl)inulin] to get the complex API-(GdL1 )x with intent to slow down the rotational correlation time (tauR ) of the macromolecular complex. The evaluation of the longitudinal relaxivity at different magnetic fields and the study of the 17 O-NMR at variable temperature of the low-molecular weight compound (GdL1 ) showed a slight decrease of the tauM value (tauM310 = 331 ns vs. tauM310 = 450 ns for the GdL complex). Consequently to the increase of the size of the API-(GdL1 )x complex, the rotational correlation time becomes about 360 times longer compared to the monomeric GdL1 complex (tauR = 33,700 ps), which results in an enhanced proton relaxivity.

AB - : Essentials Plasma-derived factor X concentrate (pdFX) is used to treat hereditary factor X deficiency. pdFX pharmacokinetics, safety and efficacy were assessed in factor X-deficient women/girls. Treatment success rate was 98%; only 6 adverse events in 2 subjects were possibly pdFX related. On-demand pdFX 25 IU kg-1 was effective and safe in women/girls with factor X deficiency. SUMMARY: Background A high-purity, plasma-derived factor X concentrate (pdFX) has been approved for the treatment of hereditary FX deficiency, an autosomal recessive disorder. Objective To perform post hoc assessments of pdFX pharmacokinetics, safety and efficacy in women and girls with hereditary FX deficiency. Patients/Methods Subjects aged >= 12 years with moderate/severe FX deficiency (plasma FX activity of < 5 IU dL-1 ) received on-demand or preventive pdFX (25 IU kg-1 ) for <= 2 years. Results Of 16 enrolled subjects, 10 women and girls (aged 14-58 years [median, 25.5 years]) received 267 pdFX infusions. Mean monthly infusions per subject were higher among women and girls (2.48) than among men and boys (1.62). In women and girls, 132 assessable bleeding episodes (61 heavy menstrual bleeds, 47 joint bleeds, 15 muscle bleeds, and nine other bleeds) were treated with pdFX, with a 98% treatment success rate versus 100% in men and boys. Mean pdFX incremental recovery was similar in the two groups (2.05 IU dL-1 versus 1.91 IU dL-1 per IU kg-1 ), as was the mean half-life (29.3 h versus 29.5 h). Of 142 adverse events in women and girls, headache was the most common (12 events in six subjects). Six events (two infusion-site erythema, two fatigue, one back pain, one infusion-site pain) in two subjects were considered to be possibly pdFX related. Following the trial, pdFX was used to successfully maintain hemostasis in two subjects undergoing obstetric delivery. Conclusions pdFX was well tolerated and effective in women and girls with FX deficiency. Although women and girls had different bleeding symptoms and sites than men and boys, their pdFX pharmacokinetic profile was comparable. PMID- 29460389 TI - The remarkable vocal anatomy of the koala (Phascolarctos cinereus): insights into low-frequency sound production in a marsupial species. AB - Koalas are characterised by a highly unusual vocal anatomy, with a descended larynx and velar vocal folds, allowing them to produce calls at disproportionately low frequencies. Here we use advanced imaging techniques, histological data, classical macroscopic dissection and behavioural observations to provide the first detailed description and interpretation of male and female koala vocal anatomy. We show that both males and females have an elongated pharynx and soft palate, resulting in a permanently descended larynx. In addition, the hyoid apparatus has a human-like configuration in which paired dorsal, resilient ligaments suspend the hyoid apparatus from the skull, while the ventral parts tightly connect to the descended larynx. We also show that koalas can retract the larynx down into the thoracic inlet, facilitated by a dramatic evolutionary transformation of the ventral neck muscles. First, the usual retractors of the larynx and the hyoid have their origins deep in the thorax. Secondly, three hyoid muscles have lost their connection to the hyoid skeleton. Thirdly, the genioglossus and geniohyoid muscles are greatly increased in length. Finally, the digastric, omohyoid and sternohyoid muscles, connected by a common tendinous intersection, form a guiding channel for the dynamic down-and-up movements of the ventral hyoid parts and the larynx. We suggest that these features evolved to accommodate the low resting position of the larynx and assist in its retraction during call production. We also confirm that the edges of the intra-pharyngeal ostium have specialised to form the novel, extra-laryngeal velar vocal folds, which are much larger than the true intra-laryngeal vocal folds in both sexes, but more developed and specialised for low frequency sound production in males than in females. Our findings illustrate that strong selection pressures on acoustic signalling not only lead to the specialisation of existing vocal organs but can also result in the evolution of novel vocal structures in both sexes.

AB - OBJECTIVE: Currently, the cosmetic and medical industries are paying considerable attention to solve or prevent skin damage or diseases, such as hyperpigmentation and oxidation and free radical damage. In this study, the effective compounds in Myrica rubra fruit were extracted and studied the biological effects of these M. rubra fruit extracts. METHODS: In this study, we extracted M. rubra fruit using solutions with various ratios of water to ethanol (100:0, 50:50, 5:95) and studied the anti-melanogenesis, anti-oxidation and radical scavenging effects of these M. rubra fruit extracts on two melanoma cell lines: mouse melanoma (B16-F0) and human melanoma (A2058). The cytotoxicity, melanin synthesis, mushroom and cellular tyrosinase activities, enzyme kinetics, melanogenesis-related gene expression, melanogenesis-related protein secretion, radical DPPH scavenging activity and ROS inhibition after treatment with M. rubra fruit extracts were determined. RESULTS: The results showed that the water extract of M. rubra fruit was less cytotoxic to the melanoma cell lines, effectively inhibited melanin synthesis and tyrosinase activity and down-regulated the gene expression and protein secretion of MITF and TRP-1. In addition, the M. rubra fruit extracts also showed the abilities to scavenge DPPH free radicals and suppress ROS production. Finally, the effective compounds in the water extract were Myricetin O-deoxyhexoside, Quercetin-O-deoxyhexoside, and Kaempferol-O-hexoside determined by LC/MS/MS assay. CONCLUSION: Overall, the water extract of M. rubra fruit is a safe and effective melanin inhibitor and anti-oxidant and can be applied widely in the fields of cosmetics and medicine. PMID- 29460391 TI - Counting the Clicks in Fluorescent Polymer Networks. AB - We introduce a fluorescence-based methodology enabling the quantification of ligation points in photochemically prepared polymer networks. Well-defined alpha,omega-tetrazole-capped polymer strands prepared via RAFT polymerization are crosslinked under UV irradiation by a trimaleimide via nitrile imine mediated tetrazole-ene cycloaddition. Thus, for each linkage point a fluorescent pyrazoline ring is formed, resulting in fluorescent networks, which are degradable by aminolysis of the trithiocarbonate functionalities, leading to soluble fragments. The fluorescence emission of the soluble network fragments correlates directly with the number of pyrazoline moieties originally present in the network, thus providing a direct measure of the number of ligation points constituting the network. The herein introduced strategy based on a fluorescence readout is a powerful yet simple approach to quantify network formation processes applicable to a wide class of polymers accessible via RAFT.

AB - Dietary supplement and natural product use is increasing within the United States, resulting in growing concern for exposure in vulnerable populations, including young adults and women of child-bearing potential. Vinpocetine is a semisynthetic derivative of the Vinca minor extract, vincamine. Human exposure to vinpocetine occurs through its use as a dietary supplement for its purported nootropic and neuroprotective effects. To investigate the effects of vinpocetine on embryo-fetal development, groups of 25 pregnant Sprague-Dawley rats and 8 pregnant New Zealand White rabbits were orally administered 0, 5, 20, or 60 mg vinpocetine/kg and 0, 25, 75, 150, or 300 mg/kg daily from gestational day (GD) 6 20 and GD 7-28, respectively. Pregnant rats dosed with vinpocetine demonstrated dose-dependent increases in postimplantation loss, higher frequency of early and total resorptions, lower fetal body weights, and fewer live fetuses following administration of 60 mg/kg, in the absence of maternal toxicity. Additionally, the rat fetuses displayed dose-dependent increases in the incidences of ventricular septum defects and full supernumerary thoracolumbar ribs. Similarly, albeit at higher doses than the rats, pregnant rabbits administered vinpocetine displayed an increase in postimplantation loss and fewer live fetuses (300 mg/kg), in addition to significantly lower fetal body weights (>=75 mg/kg). In conclusion, vinpocetine exposure resulted in similar effects on embryo-fetal development in the rat and rabbit. The species differences in sensitivity and magnitude of response is likely attributable to a species difference in metabolism. Taken together, these data suggest a potential hazard for pregnant women who may be taking vinpocetine. PMID- 29460396 TI - Lower sperm quality and testicular and epididymal structural impairment in adult rats exposed to rosuvastatin during prepuberty. AB - The increase of obesity, bad eating habits and the lack of physical exercises are highly related to dyslipidemias. Rosuvastatin is a lipid-lowering drug and has been indicated to prevent cardiovascular diseases and to treat dyslipidemias due to its higher efficiency to reduce serum cholesterol concentrations. This study aimed to evaluate the reproductive adverse effects on sexual maturity due to rosuvastatin exposure in juvenile male rats during prepuberty. Three groups were randomly formed with newly weaned rats: control, whose rats received saline solution 0.9% and rosuvastatin at doses of 3 or 10 mg kg-1 day-1 , administered orally by gavage, from postnatal day 21 until preputial separation (average of 45 days for controls and 49 days for statin-treated animals), indicative of puberty onset. Male rats were maintained until sexual maturity and were killed on postnatal day 110. In the rosuvastatin-treated groups, the results showed diminished follicle-stimulating hormone, luteinizing hormone and testosterone concentrations, increased estradiol and prolactin concentrations, histopathologic alterations on testis and epididymis and decreased sperm quality. Moreover, statin-exposed groups showed decreased expression of androgen receptor on testis and epididymis and lower expression of aquaporin-9 on epididymal epithelium. In conclusion, administration of rosuvastatin to prepubertal male rats provoked long term hormonal deregulation and impaired reproduction at adulthood. PMID- 29460397 TI - Reporting quality of trial abstracts-improved yet suboptimal: A systematic review and meta-analysis. AB - OBJECTIVES: We conducted a systematic review and meta-analysis of literature to determine if the publication of the Consolidated Standards of Reporting Trials (CONSORT) abstract guideline in 2008 was followed by change in reporting quality of randomized controlled trial (RCT) abstracts. STUDY DESIGN AND SETTINGS: Evaluations were included if they compared reporting quality of RCT abstracts before and after the publication of CONSORT-abstract guideline. The literature search was performed (January 2008 to April 2017) in Medline (Ovid), EMbase, CINAHL plus and Cochrane methodologies register. We assessed study validity with a special validity tool, adapted from a previous Cochrane review. RESULTS: Initial search identified 4142 articles, of which total 10 evaluations including 5184 abstracts were included. Total 22 outcomes related to individual items of CONSORT-abstract guideline were assessed, and 14 showed significant effect sizes favoring CONSORT-abstract guideline. Despite significant effect size, the overall post-CONSORT reporting (PCR) was suboptimal for ten items: title (RR = 1.40, 95% CI 1.23 to 1.59, PCR = 53.4%), participants (RR = 1.58, 95% CI 1.11 to 2.26, PCR = 24.5%), primary outcome (RR = 1.12, 95% CI 1.02 to 1.23, PCR = 65%), blinding (RR = 2.13, 95% CI 1.20 to 3.76, PCR = 13.9%), trial status (RR = 1.81, 95% 1.39 to 2.35, PCR = 10.6%), numbers analyzed (RR = 1.51, 95% CI 1.15 to 1.98, PCR = 26.5%), outcome (RR = 1.40, 95% 1.05 to 1.86, PCR = 21.9%), effect size and precision (RR = 1.59, 95% CI 1.15 to 2.19, PCR = 58.9%), harms (RR = 1.24, 95% CI 1.04 to 1.48, PCR = 41.8%), trial registration (RR = 2.02, 95% CI 1.63 to 2.50, PCR = 33.8%). Three items with favorable effect size in addition had wide CIs: randomization (RR = -4.28, 95% CI 1.56 to 11.75, PCR = -3.3%), allocation concealment (RR = -19.89, 95% CI 1.54 to 256.69, PCR = -5.7%), and funding (RR = 22.61, 95% CI 8.13 to 62.67, PCR = -11.32%). CONCLUSION: The change in reporting quality of RCT abstracts is far from satisfactory, as evidenced by suboptimal post-CONSORT rates and wide CIs of effect sizes for majority of improved items. Mere publication of CONSORT-abstract guideline, without strict endorsement has failed to translate into good quality abstracts. PMID- 29460399 TI - Recent Progress in the Development of Conducting Polymer-Based Nanocomposites for Electrochemical Biosensors Applications: A Mini-Review. AB - Among various immobilizing materials, conductive polymer-based nanocomposites have been widely applied to fabricate the biosensors, because of their outstanding properties such as excellent electrocatalytic activity, high conductivity, and strong adsorptive ability compared to conventional conductive polymers. Electrochemical biosensors have played a significant role in delivering the diagnostic information and therapy monitoring in a rapid, simple, and low cost portable device. This paper reviews the recent developments in conductive polymer-based nanocomposites and their applications in electrochemical biosensors. The article starts with a general and concise comparison between the properties of conducting polymers and conducting polymer nanocomposites. Next, the current applications of conductive polymer-based nanocomposites of some important conducting polymers such as PANI, PPy, and PEDOT in enzymatic and nonenzymatic electrochemical biosensors are overviewed. This review article covers an 8-year period beginning in 2010. PMID- 29460398 TI - Centralization errors in comparative genomic hybridization array analysis of pituitary tumor samples. AB - Reliable interpretation of comparative genomic hybridization array (aCGH) results requires centralization and normalization of the data. We evaluated the reliability of aCGH centralization by comparing aCGH results (with classical centralization-normalization steps) to fluorescence in situ hybridization (FISH) results. In addition, we propose a method to correct centralization bias. Sixty six pituitary tumors were analyzed (Agilent aCGH + SNP 4 * 180K microarray). For each tumor, the FISH-based log2 (ratios) of a subset of chromosomes were compared with the corresponding aCGH raw log2 (ratios). With our new normalization centralization process, this difference was added to all log2 (ratios), before performing loess regression on non-altered probes only. Finally, the mean log2 (ratio) and the percentage of normal probes were compared between CGHnormaliter and our new FISH-based method. For 11 tumors, FISH results and raw CGH log2 (ratios) differed significantly. In addition, nine tumors showed discrepancies between results generated by CGHnormaliter and our new-method. Such discrepancies seemed to occur with tumours with many abnormalities (0%-40% normal probes), rather than in those tumours with fewer abnormalities (31%-100% normal probes). Five tumors had too few normal probes to allow normalization. In these tumors, which can exhibit many changes in DNA copy number, we found that centralization bias was frequent and uncorrected by current normalization methods. Therefore, an external control for centralization, such as FISH analysis, is required to insure reliable interpretation of aCGH data.

AB - Peptide-based materials are one of the most important biomaterials, with diverse structures and functionalities. Over the past few decades, a self-assembly strategy is introduced to construct peptide-based nanomaterials, which can form well-controlled superstructures with high stability and multivalent effect. More recently, peptide-based functional biomaterials are widely utilized in clinical applications. However, there is no comprehensive review article that summarizes this growing area, from fundamental research to clinic translation. In this review, the recent progress of peptide-based materials, from molecular building block peptides and self-assembly driving forces, to biomedical and clinical applications is systematically summarized. Ex situ and in situ constructed nanomaterials based on functional peptides are presented. The advantages of intelligent in situ construction of peptide-based nanomaterials in vivo are emphasized, including construction strategy, nanostructure modulation, and biomedical effects. This review highlights the importance of self-assembled peptide nanostructures for nanomedicine and can facilitate further knowledge and understanding of these nanosystems toward clinical translation.

AB - INTRODUCTION: Within higher education, there is increasing recognition that understanding the ways students experience the educational environment is critical to developing programmes that can educate our future professionals. There is a small body of literature about how students experience the dental educational environment; however, none that adopts a qualitative phenomenographic approach. This study aims to contribute to our understanding by asking what is the variation in the ways dental students experience their curriculum? METHODS: This study uses a phenomenographic methodology. Phenomenography investigates the variation in the way a group of people experience a situation, and how they ascribe meaning to it. Interviews were conducted with 14 senior dental students at the University of Sydney. Transcripts were analysed using a phenomenographic approach. RESULTS: Six increasingly sophisticated, qualitatively distinct categories of description were identified from the collective of transcripts: surviving the education system; following a guide or manual, learning how to treat teeth, learning how to meet patient treatment needs, learning how to relate with patients and understanding the complexities of dental practice. The outcome space consists of ways the categories of description are related; considering interactions with teachers, ways of coping with multiple opinions and integration of disciplinary learning. CONCLUSION: This study provides new insights into the multifaceted and relational ways that dental students experience their educational environment. It could point curriculum designers towards strategies that assist students develop sophisticated understandings about themselves as practitioners, patients and the complexities of dental practice. Suggestions about the practical implications of the findings of this research are given. PMID- 29460403 TI - Effects of ivabradine on endothelial function, aortic properties and ventricular arterial coupling in chronic systolic heart failure patients. AB - AIM: Heart rate (HR) is an important prognostic factor in patients affected by chronic heart failure (CHF); ivabradine has been demonstrated to significantly reduce nonfatal myocardial infarction and hospitalization rate for acute heart failure and to improve left ventricular (LV) reverse remodeling, quality of life, exercise capacity, and arterial elastance (Ea) in these patients. We aimed at evaluating the short-term effects of ivabradine on ventricular-arterial coupling (VAC), aortic stiffness, and endothelial function in stable patients with CHF. METHODS: We evaluated 30 consecutive CHF patients (LVEF<= 35%, NYHA class II) with sinus rhythm and HR >= 70 bpm on optimized pharmacological therapy. All of them underwent both transthoracic echocardiogram to assess aortic elastic properties (aortic distensibility, AD; aortic stiffness index, ASI; systolic aortic strain, SAS) and VAC, and peripheral arterial tonometry to measure endothelial function. Therapy with ivabradine 5 mg bid was added and each patient was evaluated with the same examinations after 4 months. RESULTS: At the baseline, 73% of patients had impaired VAC and 63% endothelial dysfunction. After 4 months, there was a significant improvement in the VAC value (DeltaVAC -0.10 +/ 0.18, P = .021), mainly linked to Ea (DeltaEa -0.40 +/- 0.23 mm Hg/mL; P = .003). All the parameters of aortic elasticity underwent significant improvement (DeltaAD 1.82 +/- 1.43 cm2 * dyn- 1, P = .004; DeltaASI -4.73 +/- 6.07, P = .033; DeltaSAS -7.98 +/- 4.37%, P = .003). Lastly, we also noted a significant improvement of endothelial function (Delta RHI 0.35 +/- 0.35; P < .001). At follow-up 40% of patients had impaired VAC (P = .018) and 33% endothelial dysfunction (P = .038). CONCLUSION: In patients with CHF adding ivabradine on top to the standard optimized medical therapy, when indicated, seems to improve endothelial function, aortic properties, and VAC.

For carotid artery stenting (CAS), computed tomography angiography is the best imaging tool to assess arch, carotid, and lesion-specific anatomy, including vessel dimensions and calcification. OCT is a coherent strategy after CAS to assess ambiguous angiographic findings and to guide appropriate therapy for dissection, thrombosis, and plaque prolapse.

AB - The current meta-analysis evaluates the relationship of late incomplete stent apposition (LISA) observed either by IVUS or OCT 6-18 months after PCI and long term outcomes, particularly in regard to stent thrombosis (ST) and has demonstrated a small but significant increase in ST with LISA. The results of the current study do not apply to acute stent malapposition whose relevance to adverse outcomes is uncertain based on current evidence and a malapposition classification based on presence, length, and severity of malapposed struts. A classification of stent malapposition based on cause of malapposition is proposed as a method to determine prognostic importance of acute incomplete stent apposition.

PMID- 29460411 TI - Associations of sleep quality with incident atrial fibrillation: a meta-analysis. AB - BACKGROUND: The strong relationship between sleep apnoea and atrial fibrillation (AF) is well known. However, it remains unclear whether the sleep quality is related with AF. AIM: To evaluate the associations of sleep duration, insomnia and frequent awakening with AF. METHODS: A systematic review was conducted in MEDLINE, EMBASE, Cochrane databases from inception through September 2017 to identify studies that evaluate the risk of AF in adults with short sleep duration, long sleep duration, insomnia and/or frequent awakening. Effect estimates from the individual study were extracted and combined using random effect, generic inverse variance method of DerSimonian and Laird. RESULTS: Ten observational studies (14 296 314 patients) were enrolled. The pooled odds ratios (ORs) of AF in individuals with short sleep (<6 h) and long sleep (>8 h) were 1.20 (95% confidence interval (CI) 0.93-1.55, I2 = 66%) and 1.24 (95% CI 0.96 1.62, I2 = 58%), respectively. There was no association between increase in sleep duration and AF, with a pooled OR of 0.97 (95% CI 0.84-1.12, I2 = 0%). However, there were significant associations of AF with insomnia and frequent awakening, with pooled ORs of 1.30 (95% CI 1.26-1.35, I2 = 3%) and 1.36 (95% CI 1.13-1.63, I2 = 55%), respectively. CONCLUSIONS: Our findings suggest an absence in association between AF and sleep duration but reveal the potential association between AF and both insomnia and frequent nocturnal awakening. As such, the further studies on association of AF and sleep qualities are warranted.

AB - This perspective covers a novel area of research describing the inadequacies of current approaches for diagnosing dysglycaemia and proposes that the 1-hour post load glucose level during the 75-g oral glucose tolerance test may serve as a novel biomarker to detect dysglycaemia earlier than currently recommended screening criteria for glucose disorders. Considerable evidence suggests that a 1 hour post-load plasma glucose value >=155 mg/dl (8.6 mmol/L) may identify individuals with reduced beta-cell function prior to progressing to prediabetes and diabetes and is highly predictive of those likely to progress to diabetes more than the HbA1c or 2-hour post-load glucose values. An elevated 1-hour post load glucose level was a better predictor of type 2 diabetes than isolated 2-hour post-load levels in Indian, Japanese, and Israeli and Nordic populations. Furthermore, epidemiological studies have shown that a 1-hour PG >=155 mg/dl (8.6 mmol/L) predicted progression to diabetes as well as increased risk for microvascular disease and mortality when the 2-hour level was <140 mg/dl (7.8 mmol/L). The risk of myocardial infarction or fatal ischemic heart disease was also greater among subjects with elevated 1-hour glucose levels as were risks of retinopathy and peripheral vascular complications in a Swedish cohort. The authors believe that the considerable evidence base supports redefining current screening and diagnostic recommendations with the 1-hour post-load level. Measurement of the 1-hour PG level would increase the likelihood of identifying a larger, high-risk group with the additional practical advantage of potentially replacing the conventional 2-hour oral glucose tolerance test making it more acceptable in a clinical setting.

AB - It is well documented that the modelling of health-related quality of life data is difficult as the distribution of such data is often strongly right/left skewed and it includes a significant percentage of observations at one. The objective of this study is to develop a series of two-part models (TPMs) that deal with these issues. Data from the UK Medical Research Council Myeloma IX trial were used to examine the relationship between the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30/QLQ-MY20 scores and the European QoL-5 Dimensions (EQ-5D) utility score. Four different TPMs were developed. The models fitted included TPM with normal regression, TPM with normal regression with variance a function of participant characteristics, TPM with log-transformed data, and TPM with gamma regression and a log link. The cohort of 1839 patients was divided into 75% derivation sample, to fit the different models, and 25% validation sample to assess the predictive ability of these models by comparing predicted and observed mean EQ-5D scores in the validation set, unadjusted R2 , and root mean square error. Predictive performance in the derivation dataset depended on the criterion used, with R2 /adjusted-R2 favouring the TPM with normal regression and mean predicted error favouring the TPM with gamma regression. The TPM with gamma regression performs best within the validation dataset under all criteria. TPM regression models provide flexible approaches to estimate mean EQ-5D utility weights from the EORTC QLQ-C30/QLQ-MY20 for use in economic evaluation. PMID- 29460412 TI - The relationship between haemoglobin level and type 1 diabetic nephropathy in Han patients in Anhui, China. AB - BACKGROUND/AIM: Recent studies have shown that low haemoglobin (Hb) levels promote the progression of chronic kidney disease. This study assessed the relationship between Hb level and type 1 diabetic nephropathy (DN) in Han patients in Anhui, China. METHODS: There was a total of 236 patients diagnosed with type 1 diabetes mellitus (T1DM) seen between January 2014 and December 2016 in our centre. Haemoglobin levels in patients with DN were compared with those without DN. The relationship between Hb level and the urinary albumin-creatinine ratio (ACR) was examined by Spearman's correlational analysis and multiple stepwise regression analysis. The binary logistic multivariate regression analysis was performed to analyse the correlated factors for type 1 DN, calculate the odds ratio (OR) and 95% confidence interval (CI). The predicting value of Hb level for DN was evaluated by area under receiver operation characteristic curve (AUROC) for discrimination and Hosmer-Lemeshow goodness-of-fit test for calibration. RESULTS: The average Hb levels in the DN group (116.1 +/- 20.8 g/L) were significantly lower than the non-DN group (131.9 +/- 14.4 g/L), P < 0.001. Hb levels were independently correlated with the urinary ACR in multiple stepwise regression analysis. The logistic multivariate regression analysis showed that the Hb level (OR: 0.936, 95% CI: 0.910-0.963, P < 0.001) was inversely correlated with DN in patients with T1DM. In sub-analysis, low Hb level (Hb < 120 g/L in female, Hb < 130 g/L in male) was still negatively associated with DN in patients with T1DM. The AUROC was 0.721 (95% CI: 0.655-0.787) in assessing the discrimination of the Hb level for DN. The value of P was 0.593 in Hosmer Lemeshow goodness-of-fit test. CONCLUSIONS: In patients with T1DM, the Hb level is inversely correlated with urinary ACR and DN.

AB - Tissue engineered constructs with rapid restoration of mechanical and biological properties remain a challenge, emphasizing the need to develop novel scaffolds. Here, we present a multicomponent composite three-dimensional scaffold structure with biomimetic reinforcement and biomolecule functionalization for meniscus tissue engineering. The scaffold structure was developed using 3:1 silk fibroin (SF) and polyvinyl alcohol (PVA). Autoclaved eggshell membrane (AESM) powder (1 3%w/v) was used as reinforcement to enhance biomechanical properties. Further to improve cell attachment and proliferation, these scaffolds were functionalized using an optimized unique combination of biomolecules. Comprehensive analysis of scaffolds was carried out on morphological, structural, mechanical and biological functionalities. Their mechanical properties were compared with different native human menisci. The results indicated that, functionalized SF-PVA with 3%AESM has shown similar order of magnitude of compressive and dynamic mechanical properties as in human meniscus. Moreover, 3% AESM based scaffolds were found to support better primary human meniscal cellular proliferation and extracellular matrix secretion. Immunohistochemical analysis revealed angiogenesis and biocompatibility with minimal inflammatory response for subcutaneously implanted scaffolds in New Zealand white rabbits. The developed reinforced and functionalized SF-PVA scaffolds can uniquely combine the potential for load bearing properties with improved in vitro and in vivo support for meniscus tissue regeneration.

PMID- 29460416 TI - Sufficient Utilization of Zirconium Ions to Improve the Structure and Surface properties of Nickel-Rich Cathode Materials for Lithium-Ion Batteries. AB - We doped Zr4+ ions in the outer layer of Ni0.8 Co0.1 Mn0.1 (OH)2 by coprecipitation. The distribution of Zr4+ in the final cathode materials showed a gradient distribution because of ion migration during the thermal treatment. The doped layer was confirmed by using various analysis methods (energy-dispersive X ray spectroscopy, XRD, X-ray photoelectron spectroscopy, and TEM), which implies that Zr4+ can not only occupy both the transition metal slabs and Li slabs but also form a Li2 ZrO3 layer on the surface as a highly ion-conductive layer. The doped Zr4+ in the transition metal slabs can stabilize the crystal structure because of the strong Zr-O bond energy, and the doped Zr4+ in the Li slabs can act as pillar ions to improve the structural stability and reduce cation mixing. The gradient doping can take advantage of the "pillar effect" and restrain the "blocking effect" of the pillar ions, which reduces irreversible capacity loss and improves the cycling and rate performance of the Ni-rich cathode materials. The capacity retention of the modified sample reached 83.2 % after 200 cycles at 1C (200 mA g-1 ) at 2.8-4.5 V, and the discharge capacity was up to 164.7 mAh g-1 at 10C. This effective strategy can improve the structure stability of the cathode material while reducing the amount of non-electrochemical active dopant because of the gradient distribution of the dopant. In addition, the highly ion conductive layer of Li2 ZrO3 on the surface can improve the rate performance of the cathode.

AB - Response to a drug often differs widely among individual patients. This variability is frequently observed not only with respect to effective responses but also with adverse drug reactions. Matching patients to the drugs that are most likely to be effective and least likely to cause harm is the goal of effective therapeutics. Pharmacogenomics (PGx) holds the promise of precision medicine through elucidating the genetic determinants responsible for pharmacological outcomes and using them to guide drug selection and dosing. Here we survey the US landscape of research programs in PGx implementation, review current advances and clinical applications of PGx, summarize the obstacles that have hindered PGx implementation, and identify the critical knowledge gaps and possible studies needed to help to address them. PMID- 29460417 TI - Seroprevalence of brucellosis in goats and sheep in Thailand: Results from the Thai National Brucellosis Surveillance System from 2013 to 2015. AB - In Thailand, brucellosis re-emerged in humans in 2003 and is considered a public health risk to goat farmers as the disease is endemic in small ruminants. The Thai Department of Livestock Development (DLD) established a nationwide surveillance system for brucellosis in goats and sheep in 1997. Using data from this surveillance system, we describe the seroprevalence of brucellosis from 2013 to 2015 in small ruminants and the spatial distribution of the disease throughout Thailand. Surveillance data collected included the number of animals and herds tested, the province of the animal and herd and the laboratory results. Seroprevalence was estimated at both the animal and herd levels. During the 3 year period, 443,561 goats and sheep were tested for brucellosis by the DLD throughout Thailand using the Rose Bengal Plate Test (RBPT) and the enzyme-linked immunosorbent assay test for Brucella. Among the 3 years, 2013 had the highest proportion of herds that tested positive for brucellosis at 13.80% (95% CI, 12.52, 15.16). Overall, this study found that brucellosis seroprevalence in small ruminants is decreasing throughout Thailand. However, there is variability in the spread of the disease with provinces in the eastern and western regions of Thailand having higher proportions of animals and herds testing positive. Overall provinces in the south had the lowest proportion of animals and herds testing positive for brucellosis. Periodic review of surveillance data documents the impact of the current brucellosis control programme and supports a targeted response in higher prevalence regions when there are limited financial resources for control measures. PMID- 29460418 TI - Reliability of histologic assessment in patients with eosinophilic oesophagitis. AB - BACKGROUND: The validity of the eosinophilic oesophagitis (EoE) histologic scoring system (EoEHSS) has been demonstrated, but only preliminary reliability data exist. AIM: Formally assess the reliability of the EoEHSS and additional histologic features. METHODS: Four expert gastrointestinal pathologists independently reviewed slides from adult patients with EoE (N = 45) twice, in random order, using standardised training materials and scoring conventions for the EoEHSS and additional histologic features agreed upon during a modified Delphi process. Intra- and inter-rater reliability for scoring the EoEHSS, a visual analogue scale (VAS) of overall histopathologic disease severity, and additional histologic features were assessed using intra-class correlation coefficients (ICCs). RESULTS: Almost perfect intra-rater reliability was observed for the composite EoEHSS scores and the VAS. Inter-rater reliability was also almost perfect for the composite EoEHSS scores and substantial for the VAS. Of the EoEHSS items, eosinophilic inflammation was associated with the highest ICC estimates and consistent with almost perfect intra- and inter-rater reliability. With the exception of dyskeratotic epithelial cells and surface epithelial alteration, ICC estimates for the remaining EoEHSS items were above the benchmarks for substantial intra-rater, and moderate inter-rater reliability. Estimation of peak eosinophil count and number of lamina propria eosinophils were associated with the highest ICC estimates among the exploratory items. CONCLUSION: The composite EoEHSS and most component items are associated with substantial reliability when assessed by central pathologists. Future studies should assess responsiveness of the score to change after a therapeutic intervention to facilitate its use in clinical trials. PMID- 29460420 TI - Goat milk: Non-invasive source for mammary epithelial cell isolation and in vitro culture. AB - Mammary epithelial cells (MECs) used to study mammary gland function in vitro are typically isolated from mammary tissue. Breast milk offers an alternative source of MECs to replace mammary gland tissue. This study aimed to isolate and culture MECs from goat milk. Samples of fresh goat milk were collected from early and late-lactating Saanen goats. Samples were subjected to isolation, culture and characterization for putative MECs. The cells adhered to the culture dishes 1 day after isolation and displayed a monolayer pattern, epithelial-like cobblestone morphology, and formed alveoli-like structures that are typical of MECs. We identified the epithelial origin of the isolated cell by staining with antibodies against cytokeratin 8, 18 and alkaline phosphatase. Moreover, some of the isolated cells expressed the stem cell marker stage-specific embryonic antigen-4. The transcription of Capra hircus beta-casein (CNS2) gene, a candidate gene for analysis of lactational function, was detected in MECs after induced differentiation. In addition, green fluorescence protein (GFP)-expressing cells could be generated from goat milk-derived MECs. This study demonstrated that goat MECs can be easily isolated from milk samples collected from early and late lactating goats. Our MECs model could be an effective model for in vitro studies of milk synthesis and gene targeting in the goat mammary gland. Isolation of MECs from goat milk rather than mammary tissue improves animal welfare and can be used as a replacement for the animal in future studies. PMID- 29460419 TI - Deafness and vestibular dysfunction in a Doberman Pinscher puppy associated with a mutation in the PTPRQ gene. AB - BACKGROUND: A congenital syndrome of hearing loss and vestibular dysfunction affects Doberman Pinschers. Its inheritance pattern is suspected to be autosomal recessive and it potentially represents a spontaneous animal model of an autosomal recessive syndromic hearing loss. HYPOTHESIS/OBJECTIVES: The objectives of this study were to use whole genome sequencing (WGS) to identify deleterious genetic variants in candidate genes associated with the syndrome and to study the prevalence of candidate variants among a population of unaffected Doberman Pinschers. ANIMALS: One affected Doberman Pinscher and 202 unaffected Doberman Pinschers. METHODS: WGS of the affected dog with filtering of variants against a database of 154 unaffected dogs of diverse breeds was performed. Confirmation of candidate variants was achieved by Sanger sequencing followed by genotyping of the control population of unaffected Doberman Pinschers. RESULTS: WGS and variant filtering identified an alteration in a gene associated with both deafness and vestibular disease in humans: protein tyrosine phosphatase, receptor type Q (PTPRQ). There was a homozygous A insertion at CFA15: 22 989 894, causing a frameshift mutation in exon 39 of the gene. This insertion is predicted to cause a protein truncation with a premature stop codon occurring after position 2054 of the protein sequence that causes 279 C-terminal amino acids to be eliminated. Prevalence of the variant was 1.5% in a cohort of 202 unaffected Doberman Pinschers; all unaffected Doberman Pinschers were heterozygous or heterozygous for the reference allele. CONCLUSION AND CLINICAL IMPORTANCE: We report the identification of a genetic alteration on the PTPRQ gene that is associated with congenital hearing and vestibular disorder in a young Doberman Pinscher dog. PMID- 29460421 TI - Tattoo-Paper Transfer as a Versatile Platform for All-Printed Organic Edible Electronics. AB - The use of natural or bioinspired materials to develop edible electronic devices is a potentially disruptive technology that can boost point-of-care testing. The technology exploits devices that can be safely ingested, along with pills or even food, and operated from within the gastrointestinal tract. Ingestible electronics can potentially target a significant number of biomedical applications, both as therapeutic and diagnostic tool, and this technology may also impact the food industry, by providing ingestible or food-compatible electronic tags that can "smart" track goods and monitor their quality along the distribution chain. Temporary tattoo-paper is hereby proposed as a simple and versatile platform for the integration of electronics onto food and pharmaceutical capsules. In particular, the fabrication of all-printed organic field-effect transistors on untreated commercial tattoo-paper, and their subsequent transfer and operation on edible substrates with a complex nonplanar geometry is demonstrated. PMID- 29460422 TI - Engineered CRISPR/Cas9 system for multiplex genome engineering of polyploid industrial yeast strains. AB - The CRISPR/Cas9 system has been widely used for multiplex genome engineering of Saccharomyces cerevisiae. However, its application in manipulating industrial yeast strains is less successful, probably due to the genome complexity and low copy numbers of gRNA expression plasmids. Here we developed an efficient CRISPR/Cas9 system for industrial yeast strain engineering by using our previously engineered plasmids with increased copy numbers. Four genes in both a diploid strain (Ethanol Red, 8 alleles in total) and a triploid strain (ATCC 4124, 12 alleles in total) were knocked out in a single step with 100% efficiency. This system was used to construct xylose-fermenting, lactate producing industrial yeast strains, in which ALD6, PHO13, LEU2, and URA3 were disrupted in a single step followed by the introduction of a xylose utilization pathway and a lactate biosynthetic pathway on auxotrophic marker plasmids. The optimized CRISPR/Cas9 system provides a powerful tool for the development of industrial yeast based microbial cell factories. PMID- 29460423 TI - Excess pneumonia and influenza hospitalizations associated with influenza epidemics in Portugal from season 1998/1999 to 2014/2015. AB - BACKGROUND: The aim of this study was to estimate excess pneumonia and influenza (P&I) hospitalizations during influenza epidemics and measure their correlation with influenza vaccine coverage in the 65 and more years old, according to the type/subtype of influenza virus. METHODS: The study period comprised week 40/1998 40/2015. Age-specific weekly P&I hospitalizations (ICD-9: 480-487) as main diagnosis were extracted from the National Hospital Discharge database. Age specific baseline hospitalization rates were estimated by autoregressive integrated moving average (ARIMA) model without time periods with excess hospitalizations. Excess hospitalizations were calculated by subtracting expected hospitalization rates from the observed during influenza epidemic periods. Correlation between excess P&I hospitalizations and influenza vaccine coverage in the elderly was measured with Pearson correlation coefficient. RESULTS: The average excess P&I hospitalizations/season was 19.4/105 (range 0-46.1/105 ), and higher excess was observed in young children with <2 years (79.8/105 ) and >=65 years (68.3/105 ). In epidemics with A(H3) dominant, the highest excess hospitalizations were observed among 65 and over. Seasons which influenza B or A(H1)pdm09 dominance the highest excess was observed in children with <2 years. High negative correlation was estimated between excess hospitalizations associated with A(H3) circulation and vaccine coverage in the elderly (r = -.653; 95% CI: -0.950 to -0.137). CONCLUSION: Over 80% of the influenza epidemics were associated with excess hospitalizations. However, excess P&I hospitalizations pattern differed from age group and circulating virus. This ecologic approach also identified a reduction in excess P&I associated with A(H3) circulation with increasing vaccine coverage in the elderly.

AB - BACKGROUND: Accurately assessing the morphology and shape of the patent ductus arteriosus (PDA) and obtaining measurements are important to avoid procedural complications. OBJECTIVES: To characterize and compare PDA morphology, shape, and dimensions with angiography and echocardiography. ANIMALS: 25 client-owned dogs with echocardiographically confirmed PDA. METHODS: Prospective case series. Imaging consisted of single plane angiography, transthoracic echocardiography from the right (TTE-R) and left (TTE-L), and two-dimensional, biplane, and three dimensional transesophageal echocardiography (TEE-2D and TEE-3D). Measurements included angiographic minimal ductal diameter (MDD), echocardiographic pulmonary ostium in a single dimension (TTE-R, TTE-L, and TEE-2D) and in perpendicular dimensions (TEE-3D) with similar measurements of the ampulla 3 mm above the MDD or pulmonary ostium. The morphology and shape of the PDA were characterized. RESULTS: Catheter-based occlusion (N = 20) and surgical ligation (N = 5) were performed without complication. Angiographic morphology was classified as type II (N = 19), type III (N = 1), and other (N = 1). Angiographic MDD and TEE-2D pulmonary ostium measurements were significantly (P = .008) but weakly correlated (r = .56); similar relationships were found for ampulla diameter measurements (P < .0001; r = .75). In general, TEE-2D did not correlate with other imaging modalities measurements. Based on TEE-3D measurements, the majority of pulmonary ostium (17/24; 71%) and ampulla (19/24; 79%) were oval. CONCLUSIONS AND CLINICAL IMPORTANCE: Measurements using different imaging modalities are not interchangeable. TEE-3D provided an en face view of the PDA that cannot be replicated with other echocardiographic techniques and demonstrated an oval shape in the majority of dogs. We propose an update to the current classification system to include additional PDA morphologies. PMID- 29460427 TI - Alcohol consumption and risk of hematological malignancies: A meta-analysis of prospective studies. AB - Current convincing evidence suggests that alcohol intake increases the risk of several carcinomas, which might subsequently lead to a recommendation toward limiting alcohol consumption. However, there are accumulating data worth meta analyzing that show a different effect on the risk of hematological malignancies. Eligible cohort studies were sought in PubMed database up to August 31, 2016. Separate analyses were performed by subtype of hematological malignancy (non Hodgkin lymphoma [NHL] and subtypes, Hodgkin lymphoma [HL], leukemia and subtypes), time status (ever, current, former), level of consumption (light, moderate, heavy), alcoholic beverage (total alcohol, beer, liquor, wine) and gender. Moderate and heavy alcohol consumption were significantly associated with reduced risk of NHL (relative risk [RR] = 0.85, 95% confidence interval [CI]: 0.80-0.90 and RR = 0.73, 95%CI: 0.60-0.89, respectively); a protective trend was also shown for light alcohol intake (RR = 0.93, 95%CI: 0.87-1.00). Specifically, beer consumption was associated with reduced NHL risk (RR = 0.88, 95%CI: 0.81 0.95). However, the association regarding other alcoholic beverages seemed null. The beneficial effects of alcohol mainly pertained to Diffuse Large B-Cell Lymphoma (DLBCL) (RR = 0.83, 95%CI: 0.77-0.89) and Follicular Lymphoma (FL) (RR = 0.85, 95%CI: 0.78-0.93). There was also no association between alcohol consumption and risk of HL or leukemias. In contrast to most solid malignancies, alcohol seems to confer a protective effect on NHL risk, especially on DLBCL and FL subtypes, with beer being notably beneficial. PMID- 29460428 TI - Genomewide Association Study of Alcohol Dependence and Related Traits in a Thai Population. AB - BACKGROUND: Alcohol use (both quantity and dependence) is moderately heritable, and genomewide association studies (GWAS) have identified risk genes in European, African, and Asian populations. The most reproducibly identified risk genes affect alcohol metabolism. Well-known functional variants at the gene encoding alcohol dehydrogenase B and other alcohol dehydrogenases affect risk in European and African ancestry populations. Similarly, variants mapped to these same genes and a well-known null variant that maps to the gene that encodes aldehyde dehydrogenase 2 (ALDH2) also affect risk in various Asian populations. In this study, we completed the first GWAS for 3 traits related to alcohol use in a Thai population recruited initially for studies of methamphetamine dependence. METHODS: All subjects were evaluated with the Thai version of the Semi-Structured Assessment for Drug Dependence and Alcoholism (SSADDA). A total of 1,045 subjects were available for analysis. Three traits were analyzed: flushing, maximum number of alcoholic beverages consumed in any lifetime 24-hour period ("MAXDRINKS"), and DSM-IV alcohol dependence criterion count. We also conducted a pleiotropy analysis with major depression, the only other psychiatric trait where summary statistics from a large-scale Asian-population GWAS are available. RESULTS: All 3 traits showed genomewide significant association with variants near ALDH2, with significance ranging from 2.01 * 10-14 (for flushing; lead single nucleotide polymorphism (SNP) PTPN11* rs143894582) to pmeta = 5.80 * 10-10 (for alcohol dependence criterion count; lead SNP rs149212747). These lead SNPs flank rs671 and span a region of over a megabase, illustrating the need for prior biological information in identifying the actual effect SNP, rs671. We also identified significant pleiotropy between major depression and flushing. CONCLUSIONS: These results are consistent with prior findings in Asian populations and add new information regarding alcohol use-depression pleiotropy. PMID- 29460429 TI - Treatment outcomes after the introduction of a new seizure management protocol. AB - BACKGROUND/AIM: The present study aims to determine qualitative outcomes of presentations with acute recurrent seizures or status epilepticus to the emergency department of our institution after the introduction of a new seizure management protocol. METHODS: We performed a retrospective analysis on two cohorts of patients for all presentations to the emergency department of our institution. Presentations were reviewed from January to July pre-protocol introduction and the same period post-protocol. Patients were included if they were treated for acute recurrent seizures or status epilepticus. The protocol applied a strict treatment regimen and used levetiracetam, valproate and phenobarbitone in place of phenytoin. RESULTS: A total of 77 patients was included from the pre-protocol cohort and 72 from the post-protocol group. There was a significant reduction in intensive care unit (ICU) admission (seven patients in cohort 1 and 0 patients in cohort 2) and adverse drug reactions (18 patients in cohort 1 and four patients in cohort 2). There was a trend towards fewer deaths. CONCLUSION: The introduction of the new seizure management protocol assessed in this study has resulted in fewer ICU admissions, adverse drug reactions and most importantly fewer patient deaths. This is likely attributable to a combination of improved efficacy of the newer antiepileptic agents and a clearly defined protocol directed therapy. PMID- 29460430 TI - Profiling children's emotion regulation behaviours. AB - Callear, Harvey, and Bimler (2016, International Journal of Behavioral Development, 41, 456) organized children's emotion regulation behaviours into a coherent structure. However, further investigation is needed to identify core patterns of these emotion regulation behaviours. To identify clusters and prototypal constellations of emotion regulation behaviours, the 85 behavioural items comprising the Children's Emotion Regulation Inventory (ChERI) were ranked by 151 parents in order of applicability, using an ordinal sorting procedure (Method of Successive Sorts). Responses were aggregated in empirical scales, for classification of the cases using hierarchical and k-means clustering. The scales were based on nine key 'hotspots' of children's emotion regulation behaviours, interpreted as Outward Engagement, Inward or Somatic Focus, Disengagement, Disruptive, Impulsive/Labile, Social Connectedness/Compliance, Generating Closeness/Intimacy, Establishing Order and Generating Disorder. Five summary styles of children's emotion regulation emerged and are characterized on those scales. These hotspots and styles provide guidance to clinicians, parents, teachers, and other invested adults to assess and support children's emotional development. Statement of contribution What is already known on this subject? Measurements of children's emotion regulation predominantly focus on internal processes and/or isolated expressions of emotion regulation behaviours. Research detailing anger and anxiety emotion regulation styles exists (e.g., Carthy, Horesh, Apter, & Gross, 2010, Journal of Psychopathology and Behavioral Assessment, 32, 23; Zalewski, Lengua, Wilson, Trancik, & Bazinet, 2011, Journal of Experimental Child Psychology, 110, 141). Callear, Harvey, and Bimler (2016, International Journal of Behavioral Development, 41, 456) developed the Children's Emotion Regulation Inventory to identify children's observable emotion regulation strategies. What does this study add? Research does not investigate which clusters of children's emotion regulation behaviours are most commonly exhibited and nor does it investigate emotion regulation behavioural styles. Examines how children's emotion regulation behaviours co-occur. Identifies nine core clusters (groupings) of emotion regulation behaviours most commonly observed to be exhibited in children. Identifies five emotion regulation behavioural styles (common co-occurring patterns of emotion regulation behaviour clusters) in children. PMID- 29460431 TI - Estimating dispersal in spatiotemporally variable environments using multievent capture-recapture modeling. AB - Dispersal is a key process in ecological and evolutionary dynamics. Spatiotemporal variation in habitat availability and characteristics has been suggested to be one of the main cause involved in dispersal evolution and has a strong influence on metapopulation dynamics. In recent decades, the study of dispersal has led to the development of capture-recapture (CR) models that allow movement between sites to be quantified, while handling imperfect detection. For studies involving numerous recapture sites, Lagrange et al. () proposed a multievent CR model that allows dispersal to be estimated while omitting site identity by distinguishing between individuals that stay and individuals that move. More recently, Cayuela et al. () extended this model to allow survival and dispersal probabilities to differ for the different types of habitat represented by several sites within a study area. Yet in both of these modeling systems, the state of sites is assumed to be static over time, which is not a realistic assumption in dynamic landscapes. For that purpose, we generalized the multievent CR model proposed by Cayuela et al. () to allow the estimation of dispersal, survival and recapture probabilities when a site may appear or disappear over time (MODEL 1) or when the characteristics of a site fluctuate over space and time (MODEL 2). This paper first presents these two new modeling systems, and then provides an illustration of their efficacy and usefulness by applying them to simulated CR data and data collected on two metapopulations of amphibians. MODEL 1 was tested using CR data recorded on a metapopulation of yellow-bellied toads (Bombina variegata). In this first empirical case, we examined whether the drying-out dynamics of ponds and the past dispersal status of an individual might affect dispersal behavior. Our study revealed that the probability of facultative dispersal (i.e., from a pond group that remained available/flooded) fluctuated between years and was higher in individuals that had previously dispersed. MODEL 2 was tested using CR data collected on a metapopulation of great crested newts (Triturus cristatus). In this second empirical example, we investigated whether the density of alpine newts (Ichthyosaura alpestris), a potential competitor, might affect the dispersal and survival of the crested newt. Our study revealed that the departure rate was lower in ponds with a high density of heterospecifics than in ponds with a low density of heterospecifics at both inter-annual and intra-annual scales. Moreover, annual survival was slightly higher in ponds with a high density of heterospecifics. Overall, our findings indicate that these multievent CR models provide a highly flexible means of modeling dispersal in dynamic landscapes.

AB - Acute scrotum, especially testicular torsion, is a common surgical emergency. A delay in diagnosis or management may lead to permanent testicular ischaemic damage. Thus, it is particularly important to differentiate testicular torsion from other acute scrotum conditions as soon as possible. Our study has retrospectively investigated 358 patients with acute scrotum admitted to our hospital from the year 2007 to 2016. We have collected a thorough history and clinical data and drew the conclusion by comparing clinical features of different acute scrotum cases, medical history, imaging and surgical findings. Therefore, we propose an innovative "Testicular Torsion (TT) Green Channel" concept. Through the combination of a comprehensive medical history, physical examination and auxiliary colour-Doppler ultrasonography, the diagnosis of testicular torsion is definite in most circumstances. Testis scintigraphy is a novel and complementary diagnostic modality that can reduce the negative exploration rate in ambiguous and certain cases. The TT Green Channel is a new concept in the management of testicular torsion.

AB - Articular cartilage (AC) has gradient features in both mechanics and histology as well as a poor regeneration ability. The repair of AC poses difficulties in both research and the clinic. In this paper, a gradient scaffold based on poly(lactic co-glycolic acid) (PLGA)-extracellular matrix was proposed. Cartilage scaffolds with a three-layer gradient structure were fabricated by PLGA through three dimensional printing, and the microstructure orientation and pore fabrication were made by decellularized extracellular matrix injection and directional freezing. The manufactured scaffold has a mechanical strength close to that of real cartilage. A quantitative optimization of the Young's modulus and shear modulus was achieved by material mechanics formulas, which achieved a more accurate mechanical bionic and a more stable interface performance because of the one-time molding process. At the same time, the scaffolds have a bionic and gradient microstructure orientation and pore size, and the stratification ratio can be quantitatively optimized by design of the freeze box and temperature simulation. In general, this paper provides a method to optimize AC scaffolds by both mechanics and histology as well as a bionic multimaterial scaffold. This paper is of significance for cell culture and clinical transplantation experiments. (c) 2018 Wiley Periodicals, Inc. J Biomed Mater Res Part A: 106A: 1664-1676, 2018. PMID- 29460434 TI - Effects of a wax organogel and alginate gel complex on holy basil (Ocimum sanctum) in vitro ruminal dry matter disappearance and gas production. AB - BACKGROUND: The objectives of this study were to: (a) select an ideal organogel for the oil phase of a novel gel encapsulation technology, (b) optimize the formulation of an organogel and sodium alginate-based gel complex, and (c) examine the rumen protective ability of the gel by measuring 48-h in vitro ruminal dry matter disappearance and gas production from encapsulated dried and ground holy basil leaves. RESULTS: A rice-bran wax and canola oil organogel was selected for the oil phase of the gel complex as this combination had a 48-h dry matter disappearance of 6%, the lowest of all organogels analyzed. The gel complex was formulated by homogenizing the organogel with a sodium alginate solution to create a low-viscosity oil-in-water emulsion. Average dry matter disappearance of gel-encapsulated holy basil was 19%, compared to 42% for the free, unprotected holy basil. However, gel encapsulation of holy basil stimulated gas production. Specifically, gas production of encapsulated holy basil was four times higher than the treatment with holy basil added on top of the gel prior to incubation rather than encapsulated within the gel. CONCLUSION: Although the gel itself was highly degradable, it is speculated encapsulation thwarted holy basil's antimicrobial activity. (c) 2018 Society of Chemical Industry. PMID- 29460435 TI - Topical pimecrolimus for paediatric cutaneous mastocytosis. AB - BACKGROUND: Most cases of paediatric cutaneous mastocytosis (CM) occur before the age of 2 years, and regression occurs in only 67% of children. Given the absence of any specific therapy, CM is usually treated symptomatically. A few publications have reported the beneficial effect of calcineurin inhibitors for CM. AIM: We sought to evaluate the clinical effectiveness and safety profile of topical pimecrolimus cream for the treatment of CM. METHODS: We performed a retrospective study of all diagnosed cases of CM treated with topical pimecrolimus 1% cream between 2013 and 2015. All patients were evaluated in a paediatric dermatology unit of a tertiary medical centre. Epidemiological, clinical and treatment data, including effectiveness and safety, were reviewed. RESULTS: In total, 18 children (11 male, 7 female; age range 3-42 months) with CM were evaluated. Of the 146 treated lesions, 39 (26.7%) disappeared and 98 (67%) faded or developed postinflammatory hyperpigmentation. Of the 119 papular lesions, 24 (16.4%) showed partial flattening and 56 (47%) became macular. Darier sign became negative in 14 (82%) of 17 patients. No topical or systemic complications were observed. CONCLUSIONS: Topical therapy with pimecrolimus 1% cream should be considered in the treatment of CM. PMID- 29460436 TI - Truncating variants of the DLG4 gene are responsible for intellectual disability with marfanoid features. AB - Marfanoid habitus (MH) combined with intellectual disability (ID) is a genetically and clinically heterogeneous group of overlapping disorders. We performed exome sequencing in 33 trios and 31 single probands to identify novel genes specific to MH-ID. After the search for variants in known disease-causing genes and non-disease-causing genes with classical approaches, we searched for variants in non-disease-causing genes whose pLI was above 0.9 (ExAC Consortium data), in which truncating variants were found in at least 3 unrelated patients. Only DLG4 gene met these criteria. Data from the literature and various databases also indicated its implication in ID. DLG4 encodes post-synaptic density protein 95 (PSD-95), a protein expressed in various tissues, including the brain. In neurons, PSD-95 is located at the post-synaptic density, and is associated with glutamatergic receptor signaling (NMDA and AMPA). PSD-95 probably participates in dendritogenesis. Two patients were heterozygous for de novo frameshift variants and one patient carried a a consensus splice site variant. Gene expression studies supported their pathogenicity through haploinsufficiency and loss-of function. Patients exhibited mild-to-moderate ID, similar marfanoid features, including a long face, high-arched palate, long and thin fingers, pectus excavatum, scoliosis and ophthalmological manifestations (nystagmus or strabismus). Our study emphasizes the role of DLG4 as a novel post-synaptic associated gene involved in syndromic ID associated with MH. PMID- 29460437 TI - Examining changes in procedural justice and their influence on problem-solving court outcomes. AB - The number of problem-solving courts has grown substantially since the mid-1990s. Research consistently indicates that participation in these courts lowers recidivism, which is often attributed to defendants' increased perceptions of procedural justice in these programs. Yet, prior studies are limited in their focus, often examining interactions with the judge in a single court or examining defendant perceptions and outcomes at a single time point. In the present study, we investigate defendant perceptions of procedural justice with judges and case managers across multiple problem-solving courts over time. Findings indicate that procedural justice varies across court actors and over time. Procedural justice is lower among judges than among case managers; however, changes in perceptions of procedural justice with the judge are associated with improved court outcomes. We suggest that defendant perceptions are variable and complex but important in explaining variations in outcomes. PMID- 29460438 TI - Does parental coaching affect children's false reports? Comparing verbal markers of deception. AB - The present study examined differences in children's true and false narratives as a function of parental coaching by comparing the verbal markers associated with deception. Children (N = 65, 4-7 years old) played the same game with an adult stranger over three consecutive days. Parents coached their children to falsely allege that they had played a second game and to generate details for the fabricated event. One week after the last play session, children were interviewed about their experiences. For children with the least amount of parental coaching, true and false reports could be distinguished by multiple verbal markers of deception (e.g., cognitive processes, temporal information, self-references). The fabricated reports of children who spent more time being coaching by a parent resembled their truthful reports. These findings have implications for real-world forensic contexts when children have been coached to make false allegations and fabricate information at the behest of a parent. PMID- 29460439 TI - The MRCI with juvenile detainees: optimizing performance or emphasizing ecological validity? AB - The Miranda Rights Comprehension Instruments (MRCI) are intended to be administered to legally involved youths in a setting free from distractions and stressors with the explicit goal of assessing the examinee's best understanding. However, marked disparities have been observed between juveniles' MRCI performance and their unassisted recall of a representative Miranda warning. We hypothesized that youths' very strong MRCI performance might be partially due to prompts and clarifications used whenever incomplete or ambiguous answers are provided. In this archival study, we systematically re-scored three MRCI instruments from 231 legally involved youths to evaluate their original responses (i.e., non-queried scoring). This approach is viewed as more ecologically valid because actual Miranda warnings are typically provided in a routine manner without assistance following each Miranda component. For the large majority of legally involved juveniles, only small differences were noted between standard and non-queried scoring. However, some dramatic decrements were observed, especially on the Comprehension of Miranda Rights-II (CMR-II). More specifically, 15.7% of CMR-II percentiles dropped precipitously by 60% or more, when using the non-queried scores. The results are discussed within the context of optimized performances versus ecological validity as applied to Miranda evaluations. PMID- 29460440 TI - Effect of continuing care for people with cocaine dependence on criminal justice sentences. AB - While continuing care for substance use treatment has been associated with reduced involvement in the criminal justice system, much of this research lacks random assignment to continuing care and so is limited by self-selection bias. This study sought to determine the impact of adding telephone-based continuing care to intensive outpatient programs on criminal justice outcomes for people with cocaine dependence. In three continuing care studies, spanning 1998-2008, participants were randomly assigned to an intensive outpatient program or an intensive outpatient program plus a telephone-based continuing care intervention. Cocaine-dependent participants from these three studies were included in the analyses, with outcomes derived from a dataset of jurisdiction-wide criminal sentences from a state sentencing agency. Multiple logistic regression was employed to examine the odds of a criminal conviction occurring in the 4 years after enrollment in a continuing care study. The results showed that, controlling for a criminal sentence in the previous year, gender, age, and continuing care study, people with cocaine dependence randomized to an intensive outpatient program plus a telephone-based continuing care intervention had 54% lower odds (p = 0.05, odds ratio = 0.46, 95% CI: 0.20-1.02) of a criminal sentence in the 4 years after enrollment in the continuing care study, compared with those randomized to an intensive outpatient program alone. We can conclude that adding telephone monitoring and counseling to intensive outpatient programs is associated with fewer criminal convictions over a 4-year follow-up period compared with intensive outpatient programs alone. PMID- 29460441 TI - The prevalence of false confessions in experimental laboratory simulations: A meta-analysis. AB - We assessed experimental false confession studies using a meta-analysis to evaluate the prevalence of false confessions across methodologies and several moderator variables. False confessions were more likely in typing task studies than in collaborative or individual cheating studies. In typing studies, speed of typing did not affect false confession rates, but placement of the forbidden key in locations that rendered errors less plausible lowered the false confession rates. False-evidence ploys increased the likelihood of false confessions. We explore implications for courts, expert witnesses, scholars, and police interrogators. PMID- 29460443 TI - Aqueous Hydrogenation of Levulinic Acid to 1,4-Pentanediol over Mo-Modified Ru/Activated Carbon Catalyst. AB - A highly efficient and green process was developed for direct conversion of levulinic acid into 1,4-pentanediol over Mo-modified Ru/activated carbon (AC) catalyst in a continuous fixed-bed reactor. The Ru-MoOx /AC catalyst was found to be efficient for the aqueous-phase hydrogenation of levulinic acid to 1,4 pentanediol, whereby a high yield (96.7 mol %) of 1,4-pentanediol was obtained under mild reaction conditions (70 degrees C, 4 MPa H2 ). PMID- 29460442 TI - Fluorescent nanodiamond-bacteriophage conjugates maintain host specificity. AB - Rapid identification of specific bacterial strains within clinical, environmental, and food samples can facilitate the prevention and treatment of disease. Fluorescent nanodiamonds (FNDs) are being developed as biomarkers in biology and medicine, due to their excellent imaging properties, ability to accept surface modifications, and lack of toxicity. Bacteriophages, the viruses of bacteria, can have exquisite specificity for certain hosts. We propose to exploit the properties of FNDs and phages to develop phages conjugated with FNDs as long-lived fluorescent diagnostic reagents. In this study, we develop a simple procedure to create such fluorescent probes by functionalizing the FNDs and phages with streptavidin and biotin, respectively. We find that the FND-phage conjugates retain the favorable characteristics of the individual components and can discern their proper host within a mixture. This technology may be further explored using different phage/bacteria systems, different FND color centers and alternate chemical labeling schemes for additional means of bacterial identification and new single-cell/virus studies. PMID- 29460444 TI - Association of fecal calprotectin concentrations with disease severity, response to treatment, and other biomarkers in dogs with chronic inflammatory enteropathies. AB - BACKGROUND: Calprotectin is a marker of inflammation, but its clinical utility in dogs with chronic inflammatory enteropathies (CIE) is unknown. OBJECTIVE: Evaluation of fecal calprotectin in dogs with biopsy-confirmed CIE. ANIMALS: 127 dogs. METHODS: Prospective case-control study. Dogs were assigned a canine chronic enteropathy clinical activity index (CCECAI) score, and histologic lesions severity was assessed. Fecal calprotectin, fecal S100A12, and serum C reactive protein (CRP) were measured. Food- or antibiotic-responsive cases (FRE/ARE, n = 13) were distinguished from steroid-/immunosuppressant-responsive or -refractory cases (SRE/IRE, n = 20). Clinical response to treatment in SRE/IRE dogs was classified as complete remission (CR), partial response (PR), or no response (NR). RESULTS: Fecal calprotectin correlated with CCECAI (rho = 0.27, P = .0065) and fecal S100A12 (rho = 0.90, P < .0001), some inflammatory criteria, and cumulative inflammation scores, but not serum CRP (rho = 0.16, P = .12). Dogs with SRE/IRE had higher fecal calprotectin concentrations (median: 2.0 MUg/g) than FRE/ARE dogs (median: 1.4 MUg/g), and within the SRE/IRE group, dogs with PR/NR had higher fecal calprotectin (median: 37.0 MUg/g) than dogs with CR (median: 1.6 MUg/g). However, both differences did not reach statistical significance (both P = .10). A fecal calprotectin >=15.2 MUg/g separated both groups with 80% sensitivity (95% confidence interval [95%CI]: 28%-100%) and 75% specificity (95%CI: 43%-95%). CONCLUSIONS AND CLINICAL IMPORTANCE: Fecal calprotectin could be a useful surrogate marker of disease severity in dogs with CIE, but larger longitudinal studies are needed to evaluate its utility in predicting the response to treatment. PMID- 29460445 TI - Microvesicles in hepatic and peripheral vein can predict nonresponse to corticosteroid therapy in severe alcoholic hepatitis. AB - BACKGROUND: Severe alcoholic hepatitis patients have high mortality and limited response to corticosteroids. Microvesicles reflect cellular stress and disease conditions. AIMS: To investigate whether microvesicles are associated with severity, response to steroid therapy and inflammation in severe alcoholic hepatitis. METHODS: Microvesicles originating from different cells were studied pre-therapy in 101 patients; (71 responder to corticosteroid therapy and 30 nonresponders) and 20 healthy controls. Microvesicles and cells were determined in peripheral and hepatic vein samples using flow cytometry and correlated with outcomes. Inflammatory signalling pathways and functional alterations of immune cells after stimulation with microvesicles were also investigated. RESULTS: Microvesicles mean levels were higher in nonresponders for T cells (CD3+ CD4+ ; 10.1 MV/MUL vs 5.4; P = 0.06), macrophages (CD68+ CD11b+ ; 136.5 vs 121.9 MV/MUL; P = 0.01), haematopoietic stem-cells (CD45+ CD34+ ; 116.8 vs 13.4 MV/MUL; P = 0.0001) and hepatocytes (ASGPR+ ; 470 vs 361 MV/MUL; P = 0.01); the latter two predicting steroid nonresponse in 94% patients at baseline in peripheral plasma. Microvesicle levels correlated with histological and liver disease severity indices. Whereas, in non-responders hepatic vein CD34+ cells were lower (P = 0.02), the CD34+ microvesicles there from were higher (P = 0.04), thus suggesting impaired regeneration. Also, microvesicles of 0.2-0.4 MUm size were higher in nonresponders (P < 0.03) at baseline. Microvesicles from patients trigger more (P = 0.04) ROS generation, TNF-alpha production (P = 0.04) and up-regulate pro inflammatory cytokine related genes in neutrophils in vitro. CONCLUSIONS: Pre therapy peripheral plasma levels of CD34+ and ASGPR+ microvesicles are reliable non-invasive markers of steroid nonresponse and mortality in patients with severe alcoholic hepatitis.

PMID- 29460446 TI - Effect of sotalol on heart rate, QT interval, and atrial fibrillation cycle length in horses with atrial fibrillation. AB - BACKGROUND: Based on its pharmacokinetic profile and electrophysiological effects in healthy horses, sotalol potentially could be used as a long-term PO antiarrhythmic drug in horses. OBJECTIVES: To evaluate the effect of sotalol on heart rate (HR), QT interval, atrial fibrillatory rate, and success of cardioversion in horses with naturally occurring chronic atrial fibrillation (AF). ANIMALS: Twenty-eight horses referred for transvenous electrical cardioversion of AF were treated with 2 mg/kg sotalol PO q12h for 3 days before cardioversion, and 13 horses underwent the same protocol without sotalol administration. METHODS: Retrospective study. Before and after sotalol or no treatment, the HR was measured at rest and during an exercise test. The QT interval and atrial fibrillation cycle length (AFCL) were measured at rest using tissue Doppler velocity imaging. RESULTS: In the control group, no significant differences were found between the 2 examinations. In the sotalol group, the HR at rest and during exercise was significantly lower after sotalol treatment, whereas the QT interval and AFCL measured by tissue Doppler increased significantly. Cardioversion to sinus rhythm was achieved in 25/28 horses in the sotalol group and all horses in the control group, but the median number of shocks and energy at cardioversion were significantly lower in the sotalol group. CONCLUSIONS AND CLINICAL IMPORTANCE: In horses with AF, sotalol administration results in class III antiarrhythmic effects and beta-blocking activity, with moderate HR reduction during exercise. PMID- 29460448 TI - T-cell modulation by cyclophosphamide for tumour therapy. AB - The power of T cells for cancer treatment has been demonstrated by the success of co-inhibitory receptor blockade and adoptive T-cell immunotherapies. These treatments are highly successful for certain cancers, but are often personalized, expensive and associated with harmful side effects. Other T-cell-modulating drugs may provide additional means of improving immune responses to tumours without these disadvantages. Conventional chemotherapeutic drugs are traditionally used to target cancers directly; however, it is clear that some also have significant immune-modulating effects that can be harnessed to target tumours. Cyclophosphamide is one such drug; used at lower doses than in mainstream chemotherapy, it can perturb immune homeostasis, tipping the balance towards generation of anti-tumour T-cell responses and control of cancer growth. This review discusses its growing reputation as an immune-modulator whose multiple effects synergize with the microbiota to tip the balance towards tumour immunity offering widespread benefits as a safe, and relatively inexpensive component of cancer immunotherapy. PMID- 29460449 TI - Powerful and robust cross-phenotype association test for case-parent trios. AB - There has been increasing interest in identifying genes within the human genome that influence multiple diverse phenotypes. In the presence of pleiotropy, joint testing of these phenotypes is not only biologically meaningful but also statistically more powerful than univariate analysis of each separate phenotype accounting for multiple testing. Although many cross-phenotype association tests exist, the majority of such methods assume samples composed of unrelated subjects and therefore are not applicable to family-based designs, including the valuable case-parent trio design. In this paper, we describe a robust gene-based association test of multiple phenotypes collected in a case-parent trio study. Our method is based on the kernel distance covariance (KDC) method, where we first construct a similarity matrix for multiple phenotypes and a similarity matrix for genetic variants in a gene; we then test the dependency between the two similarity matrices. The method is applicable to either common variants or rare variants in a gene, and resulting tests from the method are by design robust to confounding due to population stratification. We evaluated our method through simulation studies and observed that the method is substantially more powerful than standard univariate testing of each separate phenotype. We also applied our method to phenotypic and genotypic data collected in case-parent trios as part of the Genetics of Kidneys in Diabetes (GoKinD) study and identified a genome-wide significant gene demonstrating cross-phenotype effects that was not identified using standard univariate approaches.

AB - The newly developed AspID PCR assay for detection of Aspergillus spp. was evaluated with an interlaboratory quality control programme panel and human bronchoalveolar lavage fluid (BALF) samples. With the quality control programme, 8 out of 9 panel members were correctly identified. With the clinical study, 36 BALF samples that had been obtained from 18 patients with invasive pulmonary aspergillosis (IPA) and 18 without IPA were investigated. Sensitivity, specificity, positive and negative likelihood ratio for the AspID assay were 94.1% (95% CI 73.3-99.9), 76.5% (95% CI 50.1-93.2), 4 (95% CI 1.7-9.5) and 0.1 (95% CI 0.01-0.5) respectively. PMID- 29460451 TI - Muscles and fascial elements of the antebrachium and manus of the African elephant (Loxodonta africana, Blumenbach 1797): starring comparative and functional considerations. AB - The structure of the limbs of elephants is unusual among mammals. In African elephants (Loxodonta africana, Blumenbach 1797), the front limbs serve to support the greatest part of the body mass of the largest land animal. In this study, we present new and detailed anatomical data regarding muscular and specific fascial structures of the lower front limb which were examined by means of standard anatomical and histological techniques. The muscles and tendons of the forearm (antebrachium) and hand (manus) are tightly surrounded by thick, highly elastic fascial layers which fuse with the lacertus (lac.) fibrosus and the so-called ligamentum (lig.) humeroulnare. A well-developed musculus (m.) brachioradialis occupies the proximolateral aspect of the forearm and its tendon inserts together with the lac. fibrosus on the os carpi intermedium. The lac. fibrosus, the lig. humeroulnare and the m. flexor carpi radialis reveal a large proportion of elastic fibres. These three structures may play an important role in storing strain energy thus promoting energy-saving locomotion. On the palmar aspect of the carpus, metacarpus and digits, short flexor, abductor, adductor, lumbricales and interossei muscles are present, whereas supinator muscles are absent in all specimens. The short muscles of the hand together with specific dorsal tendons enable precise movements of specific toes. PMID- 29460452 TI - The effect of digital rectal exam on the 4Kscore for aggressive prostate cancer. AB - BACKGROUND: The 4Kscore is a new commercially available blood-based diagnostic test which predicts risk for aggressive, clinically significant prostate cancer on prostate biopsy. The 4Kscore is currently restricted to patients who have not had a digital rectal exam (DRE) in the previous 96 h, owing to prior mixed data suggesting that prostate specific antigen (PSA) isoforms may increase by a statistically significant-if not necessarily clinically significant-amount shortly after DRE. Our primary objective was to determine if 4Kscore test results are affected by a preceding DRE. METHODS: Participants at a Prostate Cancer Awareness Week screening event sponsored by the Prostate Conditions Education Council filled out clinical history questionnaires and had blood samples for 4Kscore testing drawn prior to DRE, then 15-45 min following DRE. Patients with prior cancer diagnosis, 5-alpha reductase inhibitor medication use, or lower urinary tract procedures in the prior 6 months were excluded, resulting in a population of 162 participants for analysis. Values were then compared to determine if there was a significant difference in 4Kscore following DRE. RESULTS: A statistically significant increase was seen in levels of 3 kallikreins measured (total PSA, free PSA, and intact PSA; median <0.03 ng/mL for all). This resulted in a small but statistically significant decrease in post-DRE 4Kscore (median absolute score decrease 0.43%). Using a 4Kscore cutoff of 7.5% resulted in reclassification of 10 patients (6.2%), nine of whom were "downgraded" from above the cutoff to below. CONCLUSIONS: If the blood draw for the 4 K score is performed after a screening DRE, there is a statistically significant difference in the 4 K score results, but in the vast majority of cases it would not affect clinical decision making.

PMID- 29460453 TI - Severe maternal morbidity due to sepsis: The burden and preventability of disease in New Zealand. AB - BACKGROUND: Sepsis is a life-threatening systemic condition that appears to be increasing in the obstetric population. Clinical detection can be difficult and may result in increased morbidity via delays in the continuum of patient care. AIMS: To describe the burden of severe maternal morbidity (SMM) caused by sepsis in New Zealand and investigate the potential preventability. METHODS: A multidisciplinary expert review panel was established to review cases of obstetric sepsis admitted to intensive care or high-dependency units over an 18 month span in New Zealand. Cases were then analysed for the characteristics of infection and their preventability. RESULTS: Fifty cases met the inclusion criteria, most commonly due to uterine, respiratory or kidney infection. Fifty per cent (25) of these cases were deemed potentially preventable, predominantly due to delays in diagnosis and treatment. CONCLUSIONS: A high index of suspicion, development of early recognition systems and multi-disciplinary training are recommended to decrease preventable cases of maternal sepsis. PMID- 29460455 TI - Brain Quantitative MRI Metrics in Astronauts as a Unique Professional Group. AB - BACKGROUND AND PURPOSE: As part of its technological sophistication, the International Space Station (ISS) Program operates a robust medical surveillance schedule for its rotating 6-person crew to control the known health risks and to address knowledge gaps related to human health in space flight environment. Recent evidence on visual impairment in a subset of ISS crew has renewed the interest in the effects of long-duration space flight on the central nervous system (CNS). Through retrospective analysis in a sample of 10 healthy astronauts, we demonstrate the utility of multimodal quantitative magnetic resonance imaging (qMRI) with diffusion tensor imaging (DTI)-based customized brain templates to examine the structural attributes of various CNS compartments in this occupational group. METHODS: The study included 10 healthy astronauts (45 55 years). All subjects had previous space flights with the median duration of 110 days. Multimodal quantitative structural imaging modalities performed and used in analyses. RESULTS: A host of CNS features are presented, which are largely commensurate with the available normative data. Remarkably, some of our findings demonstrate statistically significant positive features suggestive of structural neuroplasticity conceivably associated with the professional activities of astronauts, and compensatory neurogenesis that counterweighs the expected normative volume loss with age. CONCLUSIONS: The novelty of this exploratory report is in the demonstration of a qMRI toolset as a potential capability for characterization and surveillance of unique professional groups, and for future prospective examinations of the effects of various long-term exposures on CNS. PMID- 29460456 TI - Acute haemolysis, DIC and renal failure after transfusion of uncross-matched blood during trauma resuscitation: illustrative case and literature review. AB - AIMS/OBJECTIVES: The aims of this study were to report a patient with acute haemolytic transfusion reaction (HTR) after transfusing uncross-matched red blood cell (RBC) units and to identify the frequency of this complication. BACKGROUND: Uncross-matched RBC units are commonly transfused in emergencies, but the frequency of acute HTR is unknown. METHODS: We describe a male stabbing victim who received three units of uncross-matched RBC units complicated by acute intravascular HTR, disseminated intravascular coagulation (DIC) and renal failure. We identified 14 studies evaluating the frequency of acute HTR post emergency transfusion of uncross-matched RBC units. RESULTS: Acute HTR was shown by haemoglobinuria, free-plasma haemoglobin and methemalbumin, with anti-K and anti-Fya eluted from recipient red cells; acute DIC featured severe hypofibrinogenemia, thrombocytopenia, elevated fibrin D-dimer and multiple bilateral renal infarcts. Two of the three transfused units reacted with pre existing RBC alloantibodies [anti-K (titre, 128), anti-Fya (titre, 512)], explained by transfusion 25 years earlier. Our literature review found the frequency of acute HTR following emergency transfusion of uncross-matched RBC units to be 2/3998 [0.06% (95% CI, 0.01-0.21%)]. CONCLUSIONS: Although emergency transfusion of uncross-matched blood is commonly practiced at trauma centres worldwide, with low risk of acute HTR (<1/1000), our well-documented patient case demonstrates the potential for acute HTR with severe complications. PMID- 29460457 TI - Aberrant migration and surgical removal of a heartworm (Dirofilaria immitis) from the femoral artery of a cat. AB - A cat was evaluated for an acute-onset of right pelvic limb paresis. Thoracic radiographs revealed normal cardiac size and tortuous pulmonary arteries. Abdominal ultrasound identified a heartworm (HW) extending from the caudal abdominal aorta into the right external iliac artery and right femoral artery. The cat was HW-antigen positive. Echocardiography revealed a HW within the right branch of the main pulmonary artery and evidence of pulmonary hypertension. An agitated-saline contrast echocardiogram revealed a small right to left intracardiac shunt at the level of the atria. Surgical removal of the HW was performed with no substantial postoperative complications. There was return of blood flow and improved motor function to the limb. The cat remains mildly paretic on the affected limb with no other clinical signs. PMID- 29460458 TI - Thyroid function in asphyxiated newborns who received hypothermia therapy. AB - BACKGROUND: Thyroid function in asphyxiated newborns who received hypothermia therapy and its relation to neurological outcome are not well described. METHODS: We performed a prospective study to measure thyroid function in 12 asphyxiated newborns who received hypothermia therapy. We measured serum thyroid-stimulating hormone (TSH), free triiodothyronine (FT3), and free thyroxine (FT4) on admission, at 24, 72, and 96 h after birth, and at discharge (range, 17-54 days). The 12 newborns were divided into two groups based on the presence of brain injury on head magnetic resonance imaging (six in the abnormal imaging group and six in the normal imaging group), and thyroid function was compared between the two groups. RESULTS: Serum TSH was within the normal range in the 12 newborns. Serum FT3 and FT4 remained low at 24, 72, and 96 h after birth, and returned to normal range at discharge in the 12 newborns. There was no significant difference in serum TSH between the two groups, but serum FT3 at 96 h after birth, and serum FT4 at 72 and 96 h after birth, were significantly lower in the abnormal imaging group than in the normal imaging group (P = 0.02; P = 0.03; and P = 0.01, respectively). CONCLUSIONS: Asphyxiated newborns have transient low thyroid hormone levels at 24-96 h after birth. Serum FT3 and FT4 between 72 and 96 h after birth may predict brain injury in asphyxiated newborns. PMID- 29460459 TI - Prevalence of neuropathic pain and sensory alterations after dental implant placement in a university-based oral surgery department: A retrospective cohort study. AB - OBJECTIVE: To determine the prevalence and the clinical features of patients with neuropathic pain and sensory alterations after dental implant placement. BACKGROUND: Literature is very scarce concerning the prevalence of neuropathic pain after dental implant placement. PATIENTS AND METHODS: A retrospective cohort study was made in patients submitted to dental implant placement in the Dental Hospital of the University of Barcelona. A descriptive analysis of the data was made, and the 95% confidence intervals (95% CI) were calculated for the prevalences. RESULTS: The study sample was composed of 1156 subjects of whom, 1012 patients (3743 dental implants) met the study inclusion criteria. Four hundred and seventeen patients (41.2%) were male and 595 (58.8%) were female, with a mean age of 60.7 years (range 16-90 years). Three patients were diagnosed as having painful post-traumatic trigeminal neuropathy (PPTN), which corresponds to a prevalence of 0.3% (95% CI: 0%-0.6%). Additionally, 5 patients (0.5%; 95% CI: 0%-1.07%) presented trigeminal neuropathy without pain (TNWP). The combined prevalence of both disorders was 0.8% (95% CI: 0.02%-1.3%). All patients with PPTN and TNWP were 60 years old or older, with a total combined prevalence of 1.48% (95% CI: 0.46%-2.5%) in this age group. Additionally, the prevalence in this age group for women was 1.85% (95%CI: 0.38%-3.31%). CONCLUSIONS: Neuropathic pain after dental implant placement is very infrequent (0.3%) in a University Oral Surgery department. However, the presence of trigeminal neuropathies can be slightly higher and can affect up to 0.5% of patients. Older female patients seem to be more prone to this rare and disabling complication. PMID- 29460460 TI - Phosphoric Acid Catalyzed Asymmetric [2+2] Cyclization/Penicillin-Penillonic Acid Rearrangement. AB - Enantioselective synthesis of imidazolidin-5-ones through a phosphoric acid catalyzed reaction between azlactones and N-substituted beta-carbolines is reported. The reaction takes place via an initial formal [2+2] cycloaddition to generate an alpha-amino-beta-lactam, which subsequently undergoes an acid catalyzed asymmetric penicillin-penillonic acid (PPA) rearrangement with high diastereo- and enantioselectivity. To the best of our knowledge, this represents the first [2+2] cyclization of azlactones with imines and the first asymmetric PPA rearrangement, which are linked together by the phosphoric acid catalyst. PMID- 29460462 TI - Cri du Chat syndrome: Characteristics of 73 Brazilian patients. AB - BACKGROUND: Cri du Chat syndrome (CdCS) is a genetic syndrome caused by deletions in the short arm of chromosome 5. Although the main clinical features of CdCS are well known, the neurocognitive and behavioural characteristics of the phenotype are rarely described in detail in the literature. In this study, we analysed the main phenotypic features of CdCS from a parental perspective. METHOD: A questionnaire was sent to 700 Brazilian families that were registered in the Brazilian Association of CdCS. The questions involved specific domains of CdCS, such as pregnancy and birth conditions, recurrence of the disease in the family, current major health problems, and aspects of cognitive development. RESULTS: In total, 73 questionnaires were completed: 44 females and 29 males, ranging from 9.5 months old to 40 years old (mean = 13.8 years; median = 12 years). Most of the parents noticed the typical cat-like cry at birth (94.4%). The age at diagnosis of CdCS ranged from the time of birth to 180 months (mean = 14 months; median = 6 months), while one case was diagnosed during pregnancy. In all of the cases, the diagnosis of CdCS was made by G-banding karyotype analysis. In 66.2% of the cases, the parents underwent cytogenetic investigation. A total of 52.1% of the parents answered that they did not remember what the recurrence risk of CdCS was in their family. The main health problems that were reported were as follows: swallowing problems (80.3%), feeding problems (80.3%), congenital heart disease (31.5%), spine abnormalities (28.8%), and neurological symptoms (20.5%), including seizures (11%). The behavioural problems that were reported were as follows: aggressive behaviour, stereotypies, anxiety, phobias, and genital manipulation/masturbation. Neurodevelopmental delay was reported in all of the cases. Independent walking was achieved in 72.2% of the patients. Approximately 50% of the patients never presented expressive language, and most of the patients are dependent on others for their daily activities. CONCLUSIONS: The questionnaire was a pioneer initiative in the CdCS support group, and the answers used in this study can improve the health care assistance to these patients because they focus attention on the demands from a parental perspective. In addition, nearly half of the families stated that they did not remember information regarding recurrence risk, which reinforces the importance of genetic counselling follow-up and the need for the expansion of genetic services in Brazil. PMID- 29460461 TI - Expressive suppression is associated with state paranoia in psychosis: An experience sampling study on the association between adaptive and maladaptive emotion regulation strategies and paranoia. AB - OBJECTIVES: Although emotional instability and problems in emotion regulation (ER) are known to be linked to the formation and maintenance of psychosis and paranoia, it remains unclear whether the use of specific ER strategies is associated with it. The first aim of the study was to explore the association between emotional instability and paranoia. The second and third aims were to investigate whether the use of maladaptive ER strategies leads to paranoia in patients with psychosis in daily life and whether the use of more adaptive ER strategies reduces paranoia. DESIGN: A prospective momentary assessment study over the course of 6 days was performed. METHOD: Participants with psychosis (n = 32) reported repeatedly over six consecutive days on the presence and instability of positive and negative emotions, their use of adaptive (reappraisal, acceptance, distraction, social sharing, reflection) and maladaptive ER strategies (rumination, expressive suppression) and momentary paranoia in their daily life. RESULTS: Hierarchical linear regression analysis revealed that patients with psychosis who presented pronounced instability of negative emotions showed more severe levels of state paranoia. In addition, patients with psychosis who used expressive suppression when confronted with negative emotions at one point in time presented more pronounced levels of state paranoia at the following point in time. CONCLUSION: The results presented here suggest that both emotional instability and the use of expressive suppression might cause state paranoia and thus add to our understanding of causal mechanisms related to paranoia such as instability of negative emotions and the use of less adaptive ER strategies. PRACTITIONER POINTS: Maladaptive emotion regulation strategies and more pronounced instability of negative emotions are relevant to paranoia in patients with psychosis and should be a special focus of CBTp interventions. Future interventions designed for patients suffering from paranoia should promote coping with unstable negative emotions and replacing or reducing maladaptive emotion regulation strategies with adaptive ones. PMID- 29460463 TI - Association of peak atrial longitudinal strain with atrial fibrillation recurrence in patients with chronic lung diseases following radiofrequency ablation. AB - BACKGROUND: Strain was shown associated with atrial fibrillation (AF) recurrence after radiofrequency ablation (RFA), but data on AF patients complicated with chronic lung diseases (CLD) were rare. AIM: This study was designed to evaluate the relationship of baseline atrial function with AF recurrence in these patients using speckle-tracking echocardiography. METHODS: Average strain values (median: 2 days before RFA) were calculated for 87 AF patients (Mean age: 61.91 years, male: 71.26%) with CLD undergoing RFA from 2013 to 2014. Of these patients, 25 (28.74%) experienced AF recurrence during a mean follow up of 10.3 months. RESULTS: Peak right atrial longitudinal strain (R-PALS) was associated with peak left atrial longitudinal strain (L-PALS, Standardised beta = 0.45, P < 0.001) in multivariate linear regression. Multivariate Cox regression analysis showed R PALS was associated with AF recurrence (hazard ratio, 0.86; 95% confidence interval (CI), 0.78-0.96, P = 0.005) in CLD. Patients with R-PALS >=14.69% had higher AF free rate compared with R-PALS<14.69% using Kaplan-Meier analysis (log rank, P < 0.001). R-PALS had similar C-index compared to L-PALS (difference: 0.03, 95%CI: -0.06-0.12, P = 0.53) and combined R-PALS and L-PALS (difference: 0.005, 95%CI: -0.04-0.05, P = 0.84) associated with AF recurrence in CLD. CONCLUSION: R-PALS, L-PALS and combined R-PALS and L-PALS are important factors associated with AF recurrence following RFA in patients with CLD. PMID- 29460464 TI - Effect of sucralfate on gastric permeability in an ex vivo model of stress related mucosal disease in dogs. AB - BACKGROUND: Sucralfate is a gastroprotectant with no known systemic effects. The efficacy of sucralfate for prevention and treatment of stress-related mucosal diseases (SRMD) in dogs is unknown. HYPOTHESIS/OBJECTIVES: To develop a canine ex vivo model of SRMD and to determine the effect of sucralfate on mucosal barrier function in this model. ANIMALS: Gastric antral mucosa was collected immediately postmortem from 29 random-source apparently healthy dogs euthanized at a local animal control facility. METHODS: Randomized experimental trial. Sucralfate (100 mg/mL) was applied to ex vivo canine gastric mucosa concurrent with and after acid injury. Barrier function was assessed by measurement of transepithelial electrical resistance (TER) and radiolabeled mannitol flux. RESULTS: Application of acidified Ringers solution to the mucosal side of gastric antrum caused a reduction in gastric barrier function, and washout of acidified Ringers solution allowed recovery of barrier function (TER: 34.0 +/- 2.8% of control at maximum injury, 71.3 +/- 5.5% at recovery, P < .001). Sucralfate application at the time of injury or after injury significantly hastened recovery of barrier function (TER: 118.0 +/- 15.2% of control at maximum injury, P < .001 and 111.0 +/- 15.5% at recovery, P = .35). CONCLUSIONS AND CLINICAL IMPORTANCE: Sucralfate appeared effective at restoring defects in gastric barrier function induced by acid and accelerating repair of tissues subjected to acid in this model, suggesting that sucralfate could have utility for the treatment and prevention of SRMD in dogs. PMID- 29460465 TI - A study on the effect of detector resolution on gamma index passing rate for VMAT and IMRT QA. AB - The main objectives of this study are to (1) analyze the sensitivity of various gamma index passing rates using different types of detectors having different resolutions and (2) investigate the sensitivity of various gamma criteria in intensity-modulated radiation therapy (IMRT) and volumetrically modulated arc therapy (VMAT) quality assurance (QA) for the detection of systematic multileaf collimator (MLC) errors using an electronic portal imaging device (EPID) and planar (MapCheck2) and cylindrical (ArcCheck) diode arrays. We also evaluated whether the correlation between the gamma passing rate (%GP) and the percentage dose error (%DE) of the dose-volume histogram (DVH) metrics was affected by the finite spatial resolution of the array detectors. We deliberately simulated systematic MLC errors of 0.25 mm, 0.50 mm, 0.75 mm, and 1 mm in five clinical nasopharyngeal carcinoma cases, thus creating 40 plans with systematic MLC errors. All measurements were analyzed field by field using gamma criteria of 3%/3 mm, 3%/2 mm, 3%/1 mm, and 2%/2 mm, with a passing rate of 90% applied as the action level. Our results showed that 3%/1 mm is the most sensitive criterion for the detection of systematic MLC errors when using EPID, with the steepest slope from the best-fit line and an area under the receiver operating characteristic (ROC) curve >0.95. With respect to the 3%/1 mm criterion, a strong correlation between %GP and %DE of the DVH metrics was observed only when using the EPID. However, with respect to the same criteria, a 0.75 mm systematic MLC error can go undetected when using MapCheck2 and ArcCheck, with an area under the ROC curve <0.75. Furthermore, a lack of correlation between %GP and %DE of the DVH metrics was observed in MapCheck2 and ArcCheck. In conclusion, low-spatial resolution detectors can affect the results of a per-field gamma analysis and render the analysis unable to accurately separate erroneous and non-erroneous plans. Meeting these new sensitive criteria is expected to ensure clinically acceptable dose errors. PMID- 29460466 TI - The role of NFkappaB in the three stages of pregnancy - implantation, maintenance, and labour: a review article. AB - : The transcription factor nuclear factor kappa B (NFkappaB) controls the expression of over 400 genes, some of which are associated with reproductive events. During implantation, immune cells accumulate in the maternal-fetal interface; they secrete inflammatory mediators under the control of NFKB, the level of which also rises. NFKB is then downregulated to maintain gestation, but its level rises again before birth to manage prostaglandin, cytokine, and chemokine synthesis, and to stimulate uterine contraction. This review summarises the current state of knowledge about NFkappaB and its role in the molecular regulation of processes related to pregnancy development. TWEETABLE ABSTRACT: This review examines the current state of knowledge about role of NFkappaB in the development of pregnancy. PMID- 29460467 TI - Variability of sun-induced chlorophyll fluorescence according to stand age related processes in a managed loblolly pine forest. AB - Leaf fluorescence can be used to track plant development and stress, and is considered the most direct measurement of photosynthetic activity available from remote sensing techniques. Red and far-red sun-induced chlorophyll fluorescence (SIF) maps were generated from high spatial resolution images collected with the HyPlant airborne spectrometer over even-aged loblolly pine plantations in North Carolina (United States). Canopy fluorescence yield (i.e., the fluorescence flux normalized by the light absorbed) in the red and far-red peaks was computed. This quantifies the fluorescence emission efficiencies that are more directly linked to canopy function compared to SIF radiances. Fluorescence fluxes and yields were investigated in relation to tree age to infer new insights on the potential of those measurements in better describing ecosystem processes. The results showed that red fluorescence yield varies with stand age. Young stands exhibited a nearly twofold higher red fluorescence yield than mature forest plantations, while the far-red fluorescence yield remained constant. We interpreted this finding in a context of photosynthetic stomatal limitation in aging loblolly pine stands. Current and future satellite missions provide global datasets of SIF at coarse spatial resolution, resulting in intrapixel mixture effects, which could be a confounding factor for fluorescence signal interpretation. To mitigate this effect, we propose a surrogate of the fluorescence yield, namely the Canopy Cover Fluorescence Index (CCFI) that accounts for the spatial variability in canopy structure by exploiting the vegetation fractional cover. It was found that spatial aggregation tended to mask the effective relationships, while the CCFI was still able to maintain this link. This study is a first attempt in interpreting the fluorescence variability in aging forest stands and it may open new perspectives in understanding long-term forest dynamics in response to future climatic conditions from remote sensing of SIF. PMID- 29460468 TI - Review of the role of leptin in the regulation of male reproductive function. AB - Since discovered in 1994, leptin has been thought to be a pleiotropic hormone that regulates food intake, controls energy balance in the body and influences multiple tissues in the body. Leptin plays an important mediating role in the regulation of neuroendocrine and can transmit the nutritional status signals to the reproductive-related central nervous system. Many studies have shown that leptin may play an important role in the control of reproductive function. Leptin can act on all levels of the hypothalamus-pituitary-gonadal (HPG) axis and may have local effects on the function of testis and spermatogenesis. Leptin is critical for puberty initiation and can also modulate testosterone synthesis by downregulating cAMP-dependent activation of steroidogenic genes expressions. Leptin is found to be higher in infertile men than in normal subjects. Yet, the exact role of leptin in the regulation of male reproductive function remains incomplete. The purpose of this review was to summarise the recent research about the biological effects of leptin on male reproductive system. In-depth study of leptin in reproductive system will help to reveal the pathogenesis of infertility and provide new treatment ideas for human assisted reproductive technology. PMID- 29460469 TI - Further delineation of an entity caused by CREBBP and EP300 mutations but not resembling Rubinstein-Taybi syndrome. AB - In 2016, we described that missense variants in parts of exons 30 and 31 of CREBBP can cause a phenotype that differs from Rubinstein-Taybi syndrome (RSTS). Here we report on another 11 patients with variants in this region of CREBBP (between bp 5,128 and 5,614) and two with variants in the homologous region of EP300. None of the patients show characteristics typical for RSTS. The variants were detected by exome sequencing using a panel for intellectual disability in all but one individual, in whom Sanger sequencing was performed upon clinical recognition of the entity. The main characteristics of the patients are developmental delay (90%), autistic behavior (65%), short stature (42%), and microcephaly (43%). Medical problems include feeding problems (75%), vision (50%), and hearing (54%) impairments, recurrent upper airway infections (42%), and epilepsy (21%). Major malformations are less common except for cryptorchidism (46% of males), and cerebral anomalies (70%). Individuals with variants between bp 5,595 and 5,614 of CREBBP show a specific phenotype (ptosis, telecanthi, short and upslanted palpebral fissures, depressed nasal ridge, short nose, anteverted nares, short columella, and long philtrum). 3D face shape demonstrated resemblance to individuals with a duplication of 16p13.3 (the region that includes CREBBP), possibly indicating a gain of function. The other affected individuals show a less specific phenotype. We conclude that there is now more firm evidence that variants in these specific regions of CREBBP and EP300 result in a phenotype that differs from RSTS, and that this phenotype may be heterogeneous. PMID- 29460470 TI - The inspired sine-wave technique: A novel method to measure lung volume and ventilatory heterogeneity. AB - NEW FINDINGS: What is the central question of this study? We present a new non invasive medical technology, the inspired sine-wave technique, which involves inhalation of sinusoidally fluctuating concentrations of a tracer gas. The technique requires only passive patient cooperation and can monitor different cardiorespiratory variables, such as end-expired lung volume, ventilatory heterogeneity and pulmonary blood flow. What is the main finding and its importance? In this article, we demonstrate that the measurements of end-expired lung volume are repeatable and accurate, in comparison to whole-body plethysmography, and the technique is sensitive to the changes in ventilatory heterogeneity associated with advancing age. As such, it has the potential to provide clinically valuable information. ABSTRACT: The inspired sine-wave technique (IST) is a new method that can provide simple, non-invasive cardiopulmonary measurements. Over successive tidal breaths, the concentration of a tracer gas (i.e. nitrous oxide, N2 O) is sinusoidally modulated in inspired air. Using a single-compartment tidal-ventilation lung model, the resulting amplitude/phase of the expired sine wave allows estimation of end-expired lung volume (ELV), pulmonary blood flow and three indices for ventilatory heterogeneity (VH; ELV180 /FRCpleth , ELV180 /FRCpred and ELV60 /ELV180 ). This investigation aimed to determine the repeatability and agreement of ELV with FRCpleth and, as normal ageing results in well-established changes in pulmonary structure and function, whether the IST estimates of ELV and VH are age dependent. Forty-eight healthy never-smoker participants (20-86 years) underwent traditional pulmonary function testing (e.g. spirometry, body plethysmography) and the IST test, which consisted of 4 min of quiet breathing through a face mask while inspired N2 O concentrations were oscillated in a sine-wave pattern with a fixed mean (4%) and amplitude (3%) and a period of either 180 or 60 s. The ELV180 /FRCpleth and ELV180 /FRCpred were age dependent (average decreases of 0.58 and 0.48% year-1 ), suggesting an increase in VH with advancing age. The ELV showed a mean bias of -1.09 litres versus FRCpleth , but when normalized for the effects of age this bias reduced to -0.35 litres. The IST test has potential to provide clinically useful information necessitating further study (e.g. for mechanically ventilated or obstructive lung disease patients), but these findings suggest that the increases in VH with healthy ageing must be taken into account in clinical investigations. PMID- 29460471 TI - Generation of anti-porcine CD69 monoclonal antibodies and their usefulness to evaluate early activation of cellular immunity by flow cytometric analysis. AB - T cell-mediated cellular immunity and humoral immunity are equally important for the prevention of diseases. To assess activation of human and mouse cellular immunity, early activation markers of lymphocytes are often used in flow cytometry targeting expression of CD69 molecules. Response of humoral immunity against infection or vaccination has been well investigated in pigs, but that of cellular immunity has been largely neglected due to lack of direct evaluation tools. Thus, in pig research a proper assay of antibody reacted with porcine CD69 is still unavailable. In the present study, two anti-porcine CD69 mAb-producing mouse hybridomas, 01-14-22-51 (IgG2b-kappa) and 01-22-44-102 (IgG2a-kappa), both showing fine reactivity with phorbol 12-myristate 13-acetate (PMA) and ionomycin stimulated porcine peripheral blood lymphocytes in flow cytometry, were established. When porcine peripheral blood lymphocytes were activated with PMA and ionomycin and analyzed by flow cytometry, it was found that both mAbs generated in this study stained about 70% of lymphocytes. In contrast, after an identical procedure, only 5% and 13.5% of lymphocytes were stained with anti interferon-gamma mAb and anti-tumor necrosis factor-alpha mAb, respectively. These results indicate that evaluation of cellular immunity activation turns more sensitive after using our newly generated mAbs. PMID- 29460472 TI - Dual-Native Vacancy Activated Basal Plane and Conductivity of MoSe2 with High Efficiency Hydrogen Evolution Reaction. AB - Although transition metal dichalcogenide MoSe2 is recognized as one of the low cost and efficient electrocatalysts for the hydrogen evolution reaction (HER), its thermodynamically stable basal plane and semiconducting property still hamper the electrocatalytic activity. Here, it is demonstrated that the basal plane and edges of 2H-MoSe2 toward HER can be activated by introducing dual-native vacancy. The first-principle calculations indicate that both the Se and Mo vacancies together activate the electrocatalytic sites in the basal plane and edges of MoSe2 with the optimal hydrogen adsorption free energy (DeltaGH* ) of 0 eV. Experimentally, 2D MoSe2 nanosheet arrays with a large amount of dual-native vacancies are fabricated as a catalytic working electrode, which possesses an overpotential of 126 mV at a current density of 100 mV cm-2 , a Tafel slope of 38 mV dec-1 , and an excellent long-term durability. The findings pave a rational pathway to trigger the activity of inert MoSe2 toward HER and also can be extended to other layered dichalcogenide. PMID- 29460473 TI - When a physician and a clinical ethicist collaborate for better patient care. AB - Bioethics is a relatively new addition to bedside medical care in Arab world which is characterized by a special culture that often makes blind adaptation of western ethics codes and principles; a challenge that has to be faced. To date, the American University of Beirut Medical Center is the only hospital that offers bedside ethics consultations in the Arab Region aiming towards better patient centered care. This article tackles the role of the bedside clinical ethics consultant as an active member of the medical team and the impact of such consultations on decision-making and patient-centered care. Using the case of a child with multiple medical problems and a futile medical condition, we describe how the collaboration of the medical team and the clinical ethics consultant took a comprehensive approach to accompany and lead the parents and the medical team in their decision-making process and how the consultations allowed several salient issues to be addressed. This approach proved to be effective in the Arab cultural setting and indeed did lead to better patientcentered care. PMID- 29460476 TI - Chloroquine-induced cardiomyopathy: a reversible cause of heart failure. AB - Chloroquine (CQ) and hydroxychloroquine (HCQ) are anti-rheumatic medications frequently used in the treatment of connective tissue disorders. We present the case of a 45-year-old woman with CQ-induced cardiomyopathy leading to severe heart failure. Electrocardiographic abnormalities included bifascicular block, while structural disease consisted of severe biventricular and biatrial hypertrophy. Appropriate diagnosis via endomyocardial biopsy led to cessation of CQ and subsequent dramatic improvement in symptoms and structural heart disease. Cardiac toxicity is an under-recognized adverse effect of CQ/HCQ leading to cardiomyopathy with concentric hypertrophy and conduction abnormalities, with the potential for significant morbidity and mortality. Predisposing factors for CQ/HCQ-induced cardiomyopathy have been proposed. CQ/HCQ cardiomyopathy is a phenocopy of Fabry disease, and alpha-galactosidase A polymorphism may account for some heterogeneity of disease presentation. PMID- 29460474 TI - Specific synbiotics in early life protect against diet-induced obesity in adult mice. AB - AIMS: The metabolic state of human adults is associated with their gut microbiome. The symbiosis between host and microbiome is initiated at birth, and early life microbiome perturbation can disturb health throughout life. Here, we determined how beneficial microbiome interventions in early life affect metabolic health in adulthood. METHODS: Postnatal diets were supplemented with either prebiotics (scGOS/lcFOS) or synbiotics (scGOS/lcFOS with Bifidobacterium breve M 16 V) until post-natal (PN) day 42 in a well-established rodent model for nutritional programming. Mice were subsequently challenged with a high-fat Western-style diet (WSD) for 8 weeks. Body weight and composition were monitored, as was gut microbiota composition at PN21, 42 and 98. Markers of glucose homeostasis, lipid metabolism and host transcriptomics of 6 target tissues were determined in adulthood (PN98). RESULTS: Early life synbiotics protected mice against WSD-induced excessive fat accumulation throughout life, replicable in 2 independent European animal facilities. Adult insulin sensitivity and dyslipidaemia were improved and most pronounced changes in gene expression were observed in the ileum. We observed subtle changes in faecal microbiota composition, both in early life and in adulthood, including increased abundance of Bifidobacterium. Microbiota transplantation using samples collected from synbiotics-supplemented adolescent mice at PN42 to age-matched germ-free recipients did not transfer the beneficial phenotype, indicating that synbiotics modified microbiota at PN42 is not sufficient to transfer long-lasting protection of metabolic health status. CONCLUSION: Together, these findings show the potential and importance of timing of synbiotic interventions in early life during crucial microbiota development as a preventive measure to lower the risk of obesity and improve metabolic health throughout life. PMID- 29460477 TI - A pilot evaluation of a novel First Episode and Rapid Early Intervention service for Eating Disorders (FREED). AB - This pilot study assesses the impact of FREED (First Episode Rapid Early Intervention for Eating Disorders [ED]), a novel transdiagnostic service for emerging adults with recent ED onset, on clinical outcomes. Data were collected from 56 patients and 19 carers for 12 months following enrolment. FREED patients showed significant improvements in ED and other symptoms across time. Carers also showed psychological improvements. For FREED anorexia nervosa (AN) patients, body mass index (BMI) at initial clinical assessment was similar to that of comparable patients (audit cohort) seen in our service before (16.4 vs 16.1 kg/m2 ). By start of treatment, because of their shorter wait, FREED-AN had gained weight whereas audit patients had lost (16.7 vs 15.8 kg/m2 ). This difference continued throughout treatment, and at 12 months, nearly 60% FREED-AN patients returned to a BMI of 18.5 or greater. FREED shows promise as a service model for emerging adults with EDs. PMID- 29460479 TI - Label-Free Quantitative Phosphoproteomics Reveals Regulation of Vasodilator Stimulated Phosphoprotein upon Stathmin-1 Silencing in a Pair of Isogenic Colorectal Cancer Cell Lines. AB - In this communication, we present the phosphoproteome changes in an isogenic pair of colorectal cancer cell lines, viz., the poorly metastatic HCT-116 and the highly metastatic derivative E1, upon stathmin-1 (STMN1) knockdown. The aim was to better understand how the alterations of the phosphoproteins in these cells are involved in cancer metastasis. After the phosphopeptides were enriched using the TiO2 HAMMOC approach, comparative proteomics analysis was carried out using sequential window acquisition of all theoretical mass spectra-MS. Following bioinformatics analysis using MarkerView and OneOmics platforms, we identified a list of regulated phosphoproteins that may play a potential role in signaling, maintenance of cytoskeletal structure, and focal adhesion. Among these phosphoproteins, was the actin cytoskeleton regulator protein, vasodilator stimulated phosphoprotein (VASP), where its change in phosphorylation status was found to be concomitant with STMN1-associated roles in metastasis. We further showed that silencing of stathmin-1 altered the expression, subcellular localization and phosphorylation status of VASP, which suggested that it might be associated with remodeling of the cell cytoskeleton in colorectal cancer metastasis. PMID- 29460478 TI - Routine germline BRCA1 and BRCA2 testing in patients with ovarian carcinoma: analysis of the Scottish real-life experience. AB - OBJECTIVE: To determine the rates of germline BRCA1 and BRCA2 mutations in Scottish patients with ovarian cancer, before and after a change in testing policy. DESIGN: Retrospective cohort study. SETTING: Four cancer/genetics centres in Scotland. POPULATION: Patients with ovarian cancer undergoing germline BRCA1 and BRCA2 (gBRCA1/2) sequencing before 2013 (under the 'old criteria', with selection based solely on family history), after 2013 (under the 'new criteria', with sequencing offered to newly presenting patients with non-mucinous ovarian cancer), and in the 'prevalent population' (who presented before 2013, but were not eligible for sequencing under the old criteria but were sequenced under the new criteria). METHODS: Clinicopathological and sequence data were collected before and for 18 months after this change in selection criteria. MAIN OUTCOME MEASURES: Frequency of germline BRCA1, BRCA2, RAD51C, and RAD51D mutations. RESULTS: Of 599 patients sequenced, 205, 236, and 158 were in the 'old criteria', 'new criteria', and 'prevalent' populations, respectively. The frequency of gBRCA1/2 mutations was 30.7, 13.1, and 12.7%, respectively. The annual rate of gBRCA1/2 mutation detection was 4.2 before and 20.7 after the policy change. A total of 48% (15/31) 'new criteria' patients with gBRCA1/2 mutations had a Manchester score of <15 and would not have been offered sequencing based on family history criteria. In addition, 20 patients with gBRCA1/2 were identified in the prevalent population. The prevalence of gBRCA1/2 mutations in patients aged >70 years was 8.2%. CONCLUSIONS: Sequencing all patients with non-mucinous ovarian cancer gives a much higher annual gBRCA1/2 mutation detection rate, with the frequency of positive tests still exceeding the 10% threshold upon which many family history-based models operate. TWEETABLE ABSTRACT: BRCA sequencing all non mucinous cancer patients increases mutation detection five fold.

AB - AIMS: To explore 40 years of Child Development Centre (CDC) activity and outcomes at Northampton General Hospital 1974-2014. METHODS: The study comprises 3 data sets: a published report from 1974 to 1999, an internal audit from 2001 to 2004, and more recent data collected from 2005 to 2014. The medical notes of all children who were assessed by the CDC in 2014 were reviewed, along with referral data collected by the CDC manager from this year and the preceding 10 years. RESULTS: From January 1, 1974 to December 31, 2014, 3,786 children were assessed. The male to female ratio is 2.8:1 from 2005 to 2014. Referrals for behavioural difficulties increased from 10% (10/100 referrals) in 1999-2004 to 17.8% (18/101 referrals) in 2014. Similarly, referrals for social and communication problems, "interaction" increased two and a half fold from 10% (10/100 referrals) in 1999 2004 to 26.7% (27/101 referrals) in 2014. Between 2004 and 2014, numbers of referrals for "developmental delay" halved (22.2% to 12%). CONCLUSION: We are aware of no other comparable extant UK CDC database. Services should plan for a referral rate of 6.5 per 1,000 preschool children. Between 1974 and 2014, there has clearly been a change in recorded assessment outcomes. From the mid-1980s, this reflects the change to a preschool assessment role and a shift away from purely educational outcome to include medical conditions. Covering 1974-2014, we demonstrate a clear increase in the number of referrals together with an increasing demand for assessments for social interaction and behavioural difficulties. This reflects the increased awareness of these neurodevelopmental difficulties and the changing diagnostic criteria which will now more likely result in an Autistic Spectrum Disorder diagnosis than previously. Together, these two features are most likely to have considerable implications for service development within Child Development Centres (CDCs) and Child Development Teams (CDTs). PMID- 29460481 TI - Evaluation of the benefit and use of the new terminology in endometrial cytology reporting system. AB - OBJECTIVE: The introduction and establishment of a new classification system for endometrial cytology, the "New Terminology in Endometrial Cytology (NTEMC) system," which is based on the Bethesda System for uterine cervical cytology, has recently been reported. However, the clinical management for new categories in the NTEMC system, particularly atypical endometrial cells (ATEC), has not been clarified. The objective of the present study is to determine how the ATEC category should be treated and whether the introduction of the system has decreased the number of unnecessary endometrial biopsies. METHODS: Fifty-nine cases were diagnosed as "suspicious positive" according to the three-tier reporting (TTR) system, which was adopted in Japan. The specimens were re evaluated according to the NTEMC system. Thirty-seven of the 59 patients underwent endometrial biopsy. We correlated the pathological diagnosis with the NTEMC system category. RESULTS: The 59 cases were classified according to the NTEMC system as follows: 36 cases were classified as ATEC of undetermined significance (ATEC-US), 21 cases were classified as ATEC for which atypical endometrial hyperplasia or worse cannot be excluded (ATEC-A), and 2 cases were classified as endometrial hyperplasia. The ratio of atypical endometrial hyperplasia or malignancy in ATEC-US category was significantly lower than that in ATEC-A category. Fifteen cases in ATEC-US category did not show atypical endometrial hyperplasia lesions or malignancy after 3 months. CONCLUSIONS: These data suggest that patients with ATEC-US results can be followed up for at least three months, and the introduction of the NTEMC system decreased the number of unnecessary endometrial biopsies. PMID- 29460482 TI - Electrocorticographic high-gamma modulation with passive listening paradigm for pediatric extraoperative language mapping. AB - OBJECTIVE: This prospective study compared the topography of high-gamma modulation (HGM) during a story-listening task requiring negligible patient cooperation, with the conventional electrical stimulation mapping (ESM) using a picture-naming task, for presurgical language localization in pediatric drug resistant epilepsy. METHODS: Patients undergoing extraoperative monitoring with subdural electrodes were included. Electrocorticographic signals were recorded during quiet baseline and a story-listening task. The likelihood of 70- to 150-Hz power modulation during the listening task relative to the baseline was estimated for each electrode and plotted on a cortical surface model. Sensitivity, specificity, accuracy, and diagnostic odds ratio (DOR) were estimated compared to ESM, using a meta-analytic framework. RESULTS: Nineteen patients (10 with left hemisphere electrodes) aged 4-19 years were analyzed. HGM during story listening was observed in bilateral posterior superior temporal, angular, supramarginal, and inferior frontal gyri, along with anatomically defined language association areas. Compared to either cognitive or both cognitive and orofacial sensorimotor interference with naming during ESM, left hemisphere HGM showed high specificity (0.82-0.84), good accuracy (0.66-0.70), and DOR of 2.23 and 3.24, respectively. HGM was a better classifier of ESM language sites in the left temporoparietal cortex compared to the frontal lobe. Incorporating visual naming with the story listening task substantially improved the accuracy (0.80) and DOR (13.61) of HGM mapping, while the high specificity (0.85) was retained. In the right hemisphere, no ESM sites for aphasia were seen, and the results of HGM and ESM comparisons were not significant. SIGNIFICANCE: HGM associated with story listening is a specific determinant of left hemisphere ESM language sites. It can be used for presurgical language mapping in children who cannot cooperate with conventional language tasks requiring active engagement. Incorporation of additional language tasks, if feasible, can further improve the diagnostic accuracy of language localization with HGM. PMID- 29460483 TI - Molecular cloning and expression analysis of tyr and tyrp1 genes in normal and albino yellow catfish Tachysurus fulvidraco. AB - The full-length complementary DNA of two genes related to vertebrate albinism, the tyrosinase gene tyr and tyrosinase-related protein 1 gene tyrp1, were cloned and analysed from normal and albino yellow catfish Tachysurus fulvidraco. The open reading frames (ORF) of tyr and tyrp1 encode putative peptides of 533 and 526 amino acids (amino-acid), both of which possess two conserved copper binding sites. The homologous identities of deduced amino-acid sequences showed that both Tyr and Tyrp1 of T. fulvidraco share considerable similarity with that of channel catfish Ictalurus punctatus. Both tyr and tyrp1 were expressed in a wide range of adult tissues. Tyr gene had the highest expression level in the brain of both normal and albino T. fulvidraco. Tyrp1 had the highest expression level in the skin of normal groups, and the fin of albino groups. The messenger (m)RNA expressions of tyr and tyrp1 were detectable at different early developmental stages and varied with embryonic and larval growth. Tyr and tyrp1 mRNA have obvious tissue specificity both in normal and albino T. fulvidraco and higher expression levels were detected in the normal group revealing that tyr and tyrp1 may have an important role in pigmentation. These results will provide useful data for understanding the molecular mechanism of melanin formation and the occurrence of albinism in T. fulvidraco. PMID- 29460484 TI - Sex-specific performance of pre-imaging diagnostic algorithms for pulmonary embolism. AB - : Essentials Decision rules for pulmonary embolism are used indiscriminately despite possible sex-differences. Various pre-imaging diagnostic algorithms have been investigated in several prospective studies. When analysed at an individual patient data level the algorithms perform similarly in both sexes. Estrogen use and male sex were associated with a higher prevalence in suspected pulmonary embolism. SUMMARY: Background In patients suspected of pulmonary embolism (PE), clinical decision rules are combined with D-dimer testing to rule out PE, avoiding the need for imaging in those at low risk. Despite sex differences in several aspects of the disease, including its diagnosis, these algorithms are used indiscriminately in women and men. Objectives To compare the performance, defined as efficiency and failure rate, of three pre-imaging diagnostic algorithms for PE between women and men: the Wells rule with fixed or with age adjusted D-dimer cut-off, and a recently validated algorithm (YEARS). A secondary aim was to determine the sex-specific prevalence of PE. Methods Individual patient data were obtained from six studies using the Wells rule (fixed D-dimer, n = 5; age adjusted, n = 1) and from one study using the YEARS algorithm. All studies prospectively enrolled consecutive patients with suspected PE. Main outcomes were efficiency (proportion of patients in which the algorithm ruled out PE without imaging) and failure rate (proportion of patients with PE not detected by the algorithm). Outcomes were estimated using (multilevel) logistic regression models. Results The main outcomes showed no sex differences in any of the separate algorithms. With all three, the prevalence of PE was lower in women (OR, 0.66, 0.68 and 0.74). In women, estrogen use, adjusted for age, was associated with lower efficiency and higher prevalence and D-dimer levels. Conclusions The investigated pre-imaging diagnostic algorithms for patients suspected of PE show no sex differences in performance. Male sex and estrogen use are both associated with a higher probability of having the disease. PMID- 29460485 TI - Saudi Arabian children's reasoning about religion-based exclusion. AB - This study examined how Saudi Arabian children (M = 10.50 years, SD = 1.61, Range = 8-10 years) evaluate peer exclusion based on religion when the perpetrator of exclusion was a peer or a father. Children believed that it was more acceptable for fathers than for peers to enforce exclusion and were more likely to use social conventional reasons to justify exclusion when the perpetrator was a father. The discussion focuses on how social domain theory needs to take children's cultural community into account. Statement of contribution What is already known on this subject? Research suggests that children do not defer to authority in making decisions about peer exclusion. Children tend to believe that authority figures should not order peer exclusion because it is a moral decision. What does this study add? Unlike children in other collectivist countries, children in Saudi Arabia support peer exclusion ordered by a father more than a peer. Saudi children use social conventional reasoning to justify fathers' support for peer exclusion. PMID- 29460486 TI - 2 H-fractionations during the biosynthesis of carbohydrates and lipids imprint a metabolic signal on the delta2 H values of plant organic compounds. AB - Hydrogen (H) isotope ratio (delta2 H) analyses of plant organic compounds have been applied to assess ecohydrological processes in the environment despite a large part of the delta2 H variability observed in plant compounds not being fully elucidated. We present a conceptual biochemical model based on empirical H isotope data that we generated in two complementary experiments that clarifies a large part of the unexplained variability in the delta2 H values of plant organic compounds. The experiments demonstrate that information recorded in the delta2 H values of plant organic compounds goes beyond hydrological signals and can also contain important information on the carbon and energy metabolism of plants. Our model explains where 2 H-fractionations occur in the biosynthesis of plant organic compounds and how these 2 H-fractionations are tightly coupled to a plant's carbon and energy metabolism. Our model also provides a mechanistic basis to introduce H isotopes in plant organic compounds as a new metabolic proxy for the carbon and energy metabolism of plants and ecosystems. Such a new metabolic proxy has the potential to be applied in a broad range of disciplines, including plant and ecosystem physiology, biogeochemistry and palaeoecology. PMID- 29460488 TI - Effects of cell state and staining on femtosecond laser nanosurgery. AB - Femtosecond laser nanosurgery enables precise manipulation of subcellular elements to study regeneration. However, currently it is not frequently employed probably because of its unknown consequences on the whole cell level. To better understand the associated biological response of the cell, especially in the context of different cell states and cell staining, we manipulated C2C12 myoblasts and myotubes, which were either unstained (nicotinamide adenine dinucleotide signal) or stained with MitoTracker Red. Both signals overlap well and stain similar areas in untreated cells. We chose 3 different cutting lengths and performed surgery in the cytosol along the major cell axis. The cuts resealed within several minutes independent of the cutting length. We analyzed cell area, perimeter, major and minor axis on long term. We observed significant changes in the cell area and perimeter, dependent on the staining and more pronounced in differentiated myotubes. We conclude, that laser parameters must be chosen carefully, depending on the staining of the cell, its (differentiation) state, and the extent of the cut region, such that unwanted cell responses can be avoided. Laser manipulation of C2C12 myotubes with small ablation (0.8 MUm) and large ablation (3.0 MUm). While small damages recover, larger damages lead to elimination from the syncytium. Scale bar: 20 MUm. PMID- 29460487 TI - Systematic review: probiotics in the management of lower gastrointestinal symptoms - an updated evidence-based international consensus. AB - BACKGROUND: In 2013, a systematic review and Delphi consensus reported that specific probiotics can benefit adult patients with irritable bowel syndrome (IBS) and other gastrointestinal (GI) problems. AIM: To update the consensus with new evidence. METHODS: A systematic review identified randomised, placebo controlled trials published between January 2012 and June 2017. Evidence was graded, previously developed statements were reassessed by an 8-expert panel, and agreement was reached via Delphi consensus. RESULTS: A total of 70 studies were included (IBS, 34; diarrhoea associated with antibiotics, 13; diarrhoea associated with Helicobacter pylori eradication therapy, 7; other conditions, 16). Of 15 studies that examined global IBS symptoms as a primary endpoint, 8 reported significant benefits of probiotics vs placebo. Consensus statements with 100% agreement and "high" evidence level indicated that specific probiotics help reduce overall symptom burden and abdominal pain in some patients with IBS and duration/intensity of diarrhoea in patients prescribed antibiotics or H. pylori eradication therapy, and have favourable safety. Statements with 70%-100% agreement and "moderate" evidence indicated that, in some patients with IBS, specific probiotics help reduce bloating/distension and improve bowel movement frequency/consistency. CONCLUSIONS: This updated review indicates that specific probiotics are beneficial in certain lower GI problems, although many of the new publications did not report benefits of probiotics, possibly due to inclusion of new, less efficacious preparations. Specific probiotics can relieve lower GI symptoms in IBS, prevent diarrhoea associated with antibiotics and H. pylori eradication therapy, and show favourable safety. This study will help clinicians recommend/prescribe probiotics for specific symptoms. PMID- 29460489 TI - Exercise-induced pulmonary hemorrhage in barrel racing horses in the Pacific Northwest region of the United States. AB - BACKGROUND: Exercise-induced pulmonary hemorrhage (EIPH) refers to bleeding from the lungs in association with strenuous exercise. It has been documented in race horses but little information exists on EIPH in barrel racing horses. HYPOTHESIS/OBJECTIVES: Our goals were to evaluate the presence of EIPH in barrel racing horses and estimate its prevalence in the Pacific Northwest. ANIMALS: 149 barrel racing horses enrolled at events in WA (11), ID (3), and MT (33). METHODS: Observational cross-sectional study. Data collected included signalment, history of illness, respiratory disease, race division, and pre-race medications. Endoscopy was performed and tracheobronchoscopic (TBE) EIPH score was assigned based on quantity of blood in the trachea (0 = no blood to 4 = abundance of blood within the trachea). After TBE, bronchoalveolar lavage (BAL) was performed. Erythrocyte (red blood cell, RBC) counts were obtained from bronchoalveolar lavage fluid (BALF). Statistical analysis included linear and logistic regression, Fisher's exact t test, and calculation of correlation coefficient. Significance was set at P < .05. RESULTS: The prevalence of EIPH based on TBE EIPH score was 54%. When based on BALF RBC count >1,000 cells, EIPH prevalence was 66%. Race time did not significantly affect the presence of EIPH. A significant (P < .0001) positive linear relationship between the TBE and BAL erythrocyte count was identified, but its strength was poor (r2 = .15). CONCLUSIONS AND CLINICAL IMPORTANCE: EIPH occurs in over 50% of barrel racing horses in the Pacific Northwest. Precise determination of the impact of EIPH on health of barrel racers requires further study. PMID- 29460491 TI - Corrigendum. PMID- 29460490 TI - Evaluation of sex differences in the relationship between diastolic dysfunction and thromboembolism using propensity score analysis. AB - BACKGROUND: Female sex is a risk factor for thromboembolism (TE) in atrial fibrillation (AF); however, the underlying mechanisms are unclear. We postulated that left ventricular (LV) diastolic dysfunction (LVDD) could be associated with increased thromboembolic risk in women. METHODS: From a retrospective cohort, 158 patients (female : male = 79:79) with nonvalvular AF were propensity score matched for age, presence of diabetes, hypertension, coronary artery disease, congestive heart failure, embolic history, AF type, and AF duration. Cardiac size and function and central aortic stiffness parameters were evaluated. Diastolic function was classified as normal, indeterminate, and LVDD according to recent guidelines. Surrogate markers for thromboembolism (dense spontaneous echo contrast and thrombus) were evaluated using transesophageal echocardiography. RESULTS: Surrogate markers for TE showed a trend to be more frequent in women than in men (21.5% vs 11.4%, P = .086). LVDD was more prevalent in women than in men (22.8% vs 2.5%, P < .001); however, the prevalence of indeterminate diastolic function was not different between sexes (26.6% vs 20.3%, P = .453). Surrogate markers for TE were detected mostly in women with LVDD. LV diastolic parameters showed a restrictive pattern, and aortic stiffness parameters were worse in women than in men. Women with LVDD had increased aortic stiffness compared to women with indeterminate and normal function, whereas aortic stiffness did not differ among men in all groups. Significant relations between LV diastolic function and aortic stiffness parameters were observed only in women. CONCLUSION: LVDD due to increased aortic stiffness could be related to a higher thromboembolic risk in women with AF. PMID- 29460493 TI - Changes at Molecular Microbiology for 2018. PMID- 29460492 TI - Cerebrospinal fluid Lyme multiplex assay results are not diagnostic in horses with neuroborreliosis. AB - BACKGROUND: The accuracy of the Lyme multiplex assay for the diagnosis of neuroborreliosis in horses is unknown. HYPOTHESIS/OBJECTIVES: To describe Lyme multiplex results in horses with a postmortem diagnosis of neuroborreliosis. The hypothesis was that paired serum and cerebrospinal fluid (CSF) results and a CSF : serum ratio would allow differentiation of horses with neuroborreliosis from those with other neurologic diseases. ANIMALS: Ninety horses that had neurologic examinations, serum and CSF Lyme multiplex analyses, and postmortem examination of the nervous system performed. METHODS: Retrospective study. Data collected included signalment, ante- and postmortem diagnoses, and serum and CSF Lyme multiplex results. The CSF : serum ratio was calculated by dividing CSF median fluorescent intensity (MFI) by serum MFI for each result. RESULTS: Ten horses had a final diagnosis of neuroborreliosis, 70 were diagnosed with other neurologic diseases, and 10 had no neurologic disease. Not all horses with neuroborreliosis had positive results: 4/10 had at least 1 positive serum result, 5/10 had at least 1 positive CSF result, and 3/10 had at least 1 CSF result 4-fold higher than the corresponding serum result. Results were similar for the 70 horses with other neurologic diseases: 53% had at least 1 positive serum result, 50% had at least 1 positive CSF result, and 16% had at least 1 CSF result 4-fold higher than the corresponding serum result. CONCLUSIONS AND CLINICAL IMPORTANCE: Positive Lyme multiplex results were common in horses with neurologic diseases and did not adequately differentiate horses with neuroborreliosis from horses with other disorders. PMID- 29460494 TI - The effects of prescribing varenicline on two-year health outcomes: an observational cohort study using electronic medical records. AB - AIMS: To investigate whether smokers prescribed varenicline had lower risks of serious ill-health during the 4 years following treatment compared with those prescribed nicotine replacement therapy (NRT). DESIGN: Observational cohort study of electronic medical records. SETTING: A total of 370 UK general practices sampled from the Clinical Practice Research Datalink. PARTICIPANTS: A total of 126 718 patients aged 18 and over who were issued smoking cessation prescriptions between 1 September 2006 and 31 March 2014. MEASUREMENTS: Our primary outcome was all-cause mortality within 2 years of first prescription as indicated by linked Office of National Statistics data. Our secondary outcomes were cause-specific mortality, all-cause, cause-specific hospitalization, primary care diagnosis of myocardial infarction or chronic obstructive pulmonary disease (COPD), body mass index and attendance rate to primary care within 2 years of first prescription. Risk differences and 95% confidence intervals were estimated by multivariable adjusted regression and propensity score matched regression. We used instrumental variable analysis to overcome residual confounding. FINDINGS: People prescribed varenicline were healthier at baseline than those prescribed NRT in almost all characteristics, highlighting the potential for residual confounding. Our instrumental variable analysis results found that people prescribed varenicline had a similar risk of mortality at 2 years [risk difference per 100 patients treated = 0.67, 95% confidence interval (CI) = -0.11 to 1.46)] to those prescribed NRT, and there were similar rates of all-cause hospitalization, incident primary-care diagnoses of myocardial infarction and COPD. People prescribed varenicline subsequently attended primary care less frequently. CONCLUSIONS: Smokers prescribed varenicline in primary care in the United Kingdom do not appear to be less likely to die, be hospitalized or experience a myocardial infarction or chronic obstructive pulmonary disease during the following 2 years compared with smokers prescribed nicotine replacement therapy, but they gain more weight and attend primary care less frequently. PMID- 29460496 TI - When things don't add up: quantifying impacts of multiple stressors from individual metabolism to ecosystem processing. AB - Ecosystems are exposed to multiple stressors which can compromise functioning and service delivery. These stressors often co-occur and interact in different ways which are not yet fully understood. Here, we applied a population model representing a freshwater amphipod feeding on leaf litter in forested streams. We simulated impacts of hypothetical stressors, individually and in pairwise combinations that target the individuals' feeding, maintenance, growth and reproduction. Impacts were quantified by examining responses at three levels of biological organisation: individual-level body sizes and cumulative reproduction, population-level abundance and biomass and ecosystem-level leaf litter decomposition. Interactive effects of multiple stressors at the individual level were mostly antagonistic, that is, less negative than expected. Most population- and ecosystem-level responses to multiple stressors were stronger than expected from an additive model, that is, synergistic. Our results suggest that across levels of biological organisation responses to multiple stressors are rarely only additive. We suggest methods for efficiently quantifying impacts of multiple stressors at different levels of biological organisation. PMID- 29460495 TI - Association between sleep-disordered breathing and arterial stiffness in heart failure patients with reduced or preserved ejection fraction. AB - AIMS: Sleep-disordered breathing (SDB) is associated with arterial stiffness, which may be one of the factors that lead to heart failure (HF). We examined the relationship between pulse wave velocity (PWV) and SDB in patients who have HF with reduced ejection fraction (HFrEF) and HF with preserved ejection fraction (HFpEF). METHODS AND RESULTS: We measured the apnoea-hypopnoea index (AHI) by polysomnography, echocardiographic parameters, and PWV in 221 HF patients. Age, blood pressure, and PWV were higher in HFpEF (ejection fraction > 50%, n = 70) patients than in HFrEF (ejection fraction < 50%, n = 151) patients. All HF patients were divided into three groups according to AHI: none-to-mild SDB group (AHI < 15 times/h, n = 77), moderate SDB group (15 < AHI < 30 times/h, n = 59), and severe SDB group (AHI > 30 times/h, n = 85). Although blood pressure and echocardiographic parameters did not differ among the three groups, PWV was significantly higher in the severe SDB group than in the none-to-mild and moderate SDB groups (P = 0.002). When the HFrEF and HFpEF patients were analysed separately, PWV was significantly higher in the severe SDB group than in the none to-mild and moderate SDB groups in patients with HFpEF (P = 0.002), but not in those with HFrEF (P = 0.068). In the multiple regression analysis to determine PWV, the presence of severe SDB was found to be an independent predictor of high PWV in HFpEF (beta = 0.234, P = 0.005), but not in HFrEF patients. CONCLUSIONS: Severe SDB is associated with elevated arterial stiffness and may be related to the pathophysiology of HF, especially in HFpEF patients. PMID- 29460497 TI - Atomically Dispersed Metal Sites in MOF-Based Materials for Electrocatalytic and Photocatalytic Energy Conversion. AB - Metal sites play an essential role in both electrocatalytic and photocatalytic energy conversion. The highly ordered arrangements of the organic linkers and metal nodes as well as the well-defined pore structures of metal-organic frameworks (MOFs) make them ideal substrates to support atomically dispersed metal sites (ADMSs) located in their metal nodes, linkers, and pores. Porous carbon materials doped with ADMSs can be derived from these ADMS-incorporating MOF precursors through controlled treatments. These ADMSs incorporated in pristine MOFs and MOF-derived carbon materials possess unique advantages over molecular or bulk metal-based catalysts and bridge the gap between homogeneous and heterogeneous catalysts for energy-conversion applications. This Review presents recent progress in the design and incorporation of ADMSs in MOFs and MOF derived materials for energy-conversion applications. PMID- 29460499 TI - Implications of Odera Oruka's ethics of consumerism for reducing globesity. AB - In this paper, I advance Odera Oruka's insights on the ethics of consumerism in order to draw relevant implications of his thoughts on rethinking the problem of obesity. I argue that Oruka's ethics of consumerism and his right to human minimum theory entail some salient ideas that might serve as a better ethical model for reducing the global obesity prevalence. Though Oruka's African moral philosophy is yet to receive universal attention it arguably deserves, the interests of the international and 'globesity' community would be better served learning from the contributions of an African moral theory to contemporary bioethical discourse on obesity. Oruka's moral thoughts are by constitution, a deontological and cosmopolitan call for reducing hunger in globalized world, while also indirectly, addressing obesity of the poor. I show the limitations of his ethics of consumerism, and the shortcomings of such ethics in the context of obesity of the poor. Consequently, I develop a neo-Orukan virtue based ethics that is worthy of attention in efforts towards addressing the obesity tide. No such perspective currently exists in the context of obesity; yet the exigent need for one is necessitated by the defects of the libertarian and harm principle approaches in Western bioethical discourse. PMID- 29460498 TI - The molecular epidemiology of Huntington disease is related to intermediate allele frequency and haplotype in the general population. AB - Huntington disease (HD) is the most common monogenic neurodegenerative disorder in populations of European ancestry, but occurs at lower prevalence in populations of East Asian or black African descent. New mutations for HD result from CAG repeat expansions of intermediate alleles (IAs), usually of paternal origin. The differing prevalence of HD may be related to the rate of new mutations in a population, but no comparative estimates of IA frequency or the HD new mutation rate are available. In this study, we characterize IA frequency and the CAG repeat distribution in fifteen populations of diverse ethnic origin. We estimate the HD new mutation rate in a series of populations using molecular IA expansion rates. The frequency of IAs was highest in Hispanic Americans and Northern Europeans, and lowest in black Africans and East Asians. The prevalence of HD correlated with the frequency of IAs by population and with the proportion of IAs found on the HD-associated A1 haplotype. The HD new mutation rate was estimated to be highest in populations with the highest frequency of IAs. In European ancestry populations, one in 5,372 individuals from the general population and 7.1% of individuals with an expanded CAG repeat in the HD range are estimated to have a molecular new mutation. Our data suggest that the new mutation rate for HD varies substantially between populations, and that IA frequency and haplotype are closely linked to observed epidemiological differences in the prevalence of HD across major ancestry groups in different countries. PMID- 29460500 TI - Auto- and alloantibodies against factor XIII: laboratory diagnosis and clinical consequences. AB - Acquired FXIII deficiencies caused by autoantibodies against FXIII subunits represent rare but very severe bleeding diatheses. Alloantibodies in FXIII deficient patients also cause life-threatening bleeding complications, but they develop extremely rarely. In this review we provide an overview of the diagnosis and classification of anti-FXIII antibodies and analyze 48 patients with autoimmune FXIII deficiency and four additional FXIII-deficient patients who developed anti-FXIII alloantibody. The patients were collected from peer-reviewed publications from which relevant data could be extracted. With the exception of two cases the antibodies were directed against FXIII-A. The difficulties in the diagnosis of FXIII deficiency in the presence of anti-FXIII antibodies are discussed and a scheme for the functional classification of the anti-FXIII antibodies is recommended. The three main categories are neutralizing and non neutralizing antibodies and antibodies with combined effect. The methods being used for detecting and quantifying the inhibitory effect on FXIII activation and on the transglutaminase activity of activated FXIII are summarized and techniques for the classification of neutralizing anti-FXIII antibodies are outlined. The importance of clearance studies in these cases is emphasized. Binding assays, useful for the identification of non-neutralizing and combined type antibodies, were collected from the literature and their informative power is demonstrated by examples. The most frequently occurring bleeding symptoms in patients with anti FXIII antibodies were soft tissue bleeding; intracranial bleedings also occurred, but less frequently than in inherited FXIII deficiency. Treatment of such patients is extremely challenging; the main aim should be eradication of the antibody. PMID- 29460501 TI - Implementation of a new patient education programme for renal transplant recipients. AB - BACKGROUND: Nurses' strategies regarding patient education should be informed by the best available research evidence. Clinical nurses play an essential role in implementing new patient education programmes for renal transplant recipients. AIM: This study investigated transplant nurse job satisfaction, competence, training and perceptions of quality of care in relation to the implementation of a new, evidence-based, patient education programme. This paper reports the results from the first part of an implementation study. METHODS: Data were collected in the form of a survey from 50 clinical transplant nurses at a single national transplant centre in Norway in 2015, six months after the patient education programme was implemented. A descriptive, cross-sectional design was used. RESULTS: Seventy-two percent of the respondents reported that they had sufficient knowledge about the new programme; 54.4 % stated that the new programme resulted in renal transplant recipients being better educated. The new programme was found to be more structured, patient-centered and visible for the nurses across the wards, as compared with their previous practice. Nurses with less nursing experience were significantly more motivated about the new patient education programme, than the more experienced nurses (p = 0.05). CONCLUSIONS: Nurses were generally satisfied with their new patient education practice. Knowledge derived from the research evidence on patient education was found to be valuable and transferable to everyday clinical nursing practice. PMID- 29460502 TI - Immediate biopsy of cervical cytology-negative and non-HPV-16/18 oncogenic types positive patients. AB - BACKGROUND: According to the American Society of Colposcopy and Cervical Pathology (ASCCP), a co-test is recommended for patients one year after the detection of non-HPV 16/18 viral types in association with a negative cervical cytology. In this study, we used immediate colposcopy to evaluate the risks to the patient during the one year waiting period. METHODS: We included 544 Hpv positive/cervical cytology-negative patients who underwent cervical cancer screening from June 2015 to June 2017. Cytological specimens were classified using the Bethesta method on a liquid based preparation. We used the Hybrid Capture 2 system to define HPV DNA. Biopsies were performed on all patients under colposcopy. RESULTS: Three hundred and seventy-five patients had HPV types 16/18 and 169 had non-HPV-16/18 oncogenic types. Of the 169 patients who had non-HPV 16/18 oncogenic types, 151 (89%) had no dysplasia, 16 (9.4%) had CIN 1, and 2 (1.1%) had CIN 2/CIN 3. CONCLUSION: For the patients who had cervical cytology negative/non-HPV-16/18 positive, we detected that 1.1% of these women had CIN 2 3. For this reason, by chasing the algorithm recommended by guidelines, gynecologists take risk missing a diagnosis of CIN 2 plus lesion in 1.1% of patients. PMID- 29460503 TI - Urinary liver-type fatty acid-binding protein in pediatric nephrotic syndrome and tubular dysfunction. AB - BACKGROUND: Urinary liver-type fatty acid-binding protein (uL-FABP) has recently been identified as a biomarker for kidney injury. uL-FABP excretion in pediatric relapsing nephrotic syndrome and tubular dysfunction, however, has not been reported previously. METHODS: We measured uL-FABP level in children with steroid sensitive nephrotic syndrome (SSNS), in those with tubular dysfunction, and in control subjects. RESULTS: uL-FABP was markedly increased in relapsing SSNS (median, 30.3 MUg/gCr; range, 12.6-171.0 MUg/gCr; n = 13), and also in the tubular dysfunction group (median, 164.8 MUg/gCr; range, 41.6-834.5 MUg/gCr; n = 7), compared with the control subjects (median, 3.0 MUg/gCr; range, 1.1-13.9 MUg/gCr; n = 21). uL-FABP level was significantly correlated with urinary protein excretion in the SSNS group, and in the total group. Additionally, in the SSNS group, elevated uL-FABP in the relapsing stage returned to a level similar to that in the control group on remission of NS. In the tubular dysfunction group, uL-FABP was significantly correlated with urinary beta2-microglobulin. CONCLUSION: Urinary protein amount, and the ability of the proximal tubules to reabsorb low-molecular-weight proteins, should also be considered when evaluating the clinical significance of uL-FABP as a biomarker for kidney injury in children.

AB - Saura () claims that studies using the Probability of Connectivity metric (PC) had already demonstrated the importance of including node self-connections in network metrics. As originally defined and used, PC cannot test the importance of self-connections. However, with key terms redefined, PC could be a useful tool in future work. PMID- 29460505 TI - Identification of an algal xylan synthase indicates that there is functional orthology between algal and plant cell wall biosynthesis. AB - Insights into the evolution of plant cell walls have important implications for comprehending these diverse and abundant biological structures. In order to understand the evolving structure-function relationships of the plant cell wall, it is imperative to trace the origin of its different components. The present study is focused on plant 1,4-beta-xylan, tracing its evolutionary origin by genome and transcriptome mining followed by phylogenetic analysis, utilizing a large selection of plants and algae. It substantiates the findings by heterologous expression and biochemical characterization of a charophyte alga xylan synthase. Of the 12 known gene classes involved in 1,4-beta-xylan formation, XYS1/IRX10 in plants, IRX7, IRX8, IRX9, IRX14 and GUX occurred for the first time in charophyte algae. An XYS1/IRX10 ortholog from Klebsormidium flaccidum, designated K. flaccidumXYLAN SYNTHASE-1 (KfXYS1), possesses 1,4-beta xylan synthase activity, and 1,4-beta-xylan occurs in the K. flaccidum cell wall. These data suggest that plant 1,4-beta-xylan originated in charophytes and shed light on the origin of one of the key cell wall innovations to occur in charophyte algae, facilitating terrestrialization and emergence of polysaccharide based plant cell walls. PMID- 29460506 TI - Investigating the longitudinal association between diabetes and anxiety: a systematic review and meta-analysis. AB - AIM: Previous research has indicated an association between diabetes and anxiety. However, no synthesis has determined the direction of this association. The aim of this study was to determine the longitudinal relationship between anxiety and diabetes. METHODS: We searched seven databases for studies examining the longitudinal relationship between anxiety and diabetes. Two independent reviewers screened studies from a population aged 16 or older that examined either anxiety as a risk factor for incident diabetes or diabetes as a risk factor for incident anxiety. Studies that met eligibility criteria were put forward for data extraction and meta-analysis. RESULTS: In total 14 studies (n = 1 760 800) that examined anxiety as a risk factor for incident diabetes and two (n = 88 109) that examined diabetes as a risk factor for incident anxiety were eligible for inclusion in the review. Only studies examining anxiety as a risk factor for incident diabetes were put forward for the meta-analysis. The least adjusted (unadjusted or adjusted for age only) estimate indicated a significant association between baseline anxiety with incident diabetes (odds ratio 1.47, 1.23-1.75). Furthermore, most-adjusted analyses indicated a significant association between baseline anxiety and incident diabetes. Included studies that examined diabetes to incident anxiety found no association. CONCLUSIONS: There was an association between baseline anxiety and incident diabetes. The results also indicate the need for more research to examine the direction of association from diabetes to incident anxiety. This work adds to the growing body of evidence that poor mental health increases the risk of developing diabetes. PMID- 29460508 TI - Predatory strategies and behaviours in cephalopods are altered by elevated CO2. AB - There is increasing evidence that projected near-future carbon dioxide (CO2 ) levels can alter predator avoidance behaviour in marine invertebrates, yet little is known about the possible effects on predatory behaviours. Here we tested the effects of elevated CO2 on the predatory behaviours of two ecologically distinct cephalopod species, the pygmy squid, Idiosepius pygmaeus, and the bigfin reef squid, Sepioteuthis lessoniana. Both species exhibited an increased latency to attack and altered body pattern choice during the attack sequence at elevated CO2 . I. pygmaeus also exhibited a 20% decrease in predation rate, an increased striking distance, and reduced preference for attacking the posterior end of prey at elevated CO2 . Elevated CO2 increased activity levels of S. lessoniana comparable to those previously shown in I. pygmaeus, which could adversely affect their energy budget and increase their potential to be preyed upon. The effects of elevated CO2 on predatory behaviours, predation strategies and activity levels of cephalopods reported here could have far-reaching consequences in marine ecosystems due to the ecological importance of cephalopods in the marine food web. PMID- 29460507 TI - Bloody-minded parasites and sex: the effects of fluctuating virulence. AB - Asexual lineages can grow at a faster rate than sexual lineages. Why then is sexual reproduction so widespread? Much empirical evidence supports the Red Queen hypothesis. Under this hypothesis, coevolving parasites favour sexual reproduction by adapting to infect common asexual clones and driving them down in frequency. One limitation, however, seems to challenge the generality of the Red Queen: in theoretical models, parasites must be very virulent to maintain sex. Moreover, experiments show virulence to be unstable, readily shifting in response to environmental conditions. Does variation in virulence further limit the ability of coevolving parasites to maintain sex? To address this question, we simulated temporal variation in virulence and evaluated the outcome of competition between sexual and asexual females. We found that variation in virulence did not limit the ability of coevolving parasites to maintain sex. In fact, relatively high variation in virulence promoted parasite-mediated maintenance of sex. With sufficient variation, sexual females persisted even when mean virulence fell well below the threshold virulence required to maintain sex under constant conditions. We conclude that natural variation in virulence does not limit the relevance of the Red Queen hypothesis for natural populations; on the contrary, it could expand the range of conditions over which coevolving parasites can maintain sex. PMID- 29460509 TI - Study of the efficacy of carboxytherapy in alopecia. AB - BACKGROUND: Management of alopecia areata (AA) and androgenetic alopecia (AGA) is often challenging. The use of carboxytherapy may be a novel therapeutic option for such cases. OBJECTIVE: To evaluate the clinical efficacy and safety of carboxytherapy in alopecia areata and androgenetic alopecia. PATIENTS AND METHODS: This study was conducted on 80 patients with alopecia divided into two groups; Group I included 40 AA patients (Group IA received carboxytherapy and Group IB control received placebo), and Group II included 40 AGA patients (Group IIA received carboxytherapy and Group IIB control received placebo), and followed up monthly for 3 months. They were evaluated clinically (by assessment of Severity of Alopecia Tool (SALT) score in group I, and Sinclair scale and Norwood Hamilton scale in group II), by dermoscopy and digital dermoscopy at each visit. RESULTS: Group IA patients showed significant clinical improvement in SALT score and dermoscopic improvement after carboxytherapy and at the end of follow-up period with significant reduction in dystrophic hair, black dots, yellow dots, and tapered hair coinciding with significant emergence of regrowing hair. Group IIA patients showed significant clinical and dermoscopic improvement after carboxytherapy with significant increase in hair density measured by digital dermoscopy. However, regression of these results was observed during the follow up period but was still significantly better than before treatment. There were statistically significant improvements in clinical score, global assessments, dermoscopic, and digital dermoscopic findings in both group IA and group IIA received carboxytherapy in comparison with group IB and group IIB received placebo injections, respectively. CONCLUSION: Carboxytherapy seems to be a promising therapeutic option for patchy AA and could be helpful as an adjuvant therapy of AGA but more than 6 sessions are required and adjuvants are recommended for maintenance of the results. PMID- 29460510 TI - Confocal multispot microscope for fast and deep imaging in semicleared tissues. AB - Although perfectly transparent specimens are imaged faster with light-sheet microscopy, less transparent samples are often imaged with two-photon microscopy leveraging its robustness to scattering; however, at the price of increased acquisition times. Clearing methods that are capable of rendering strongly scattering samples such as brain tissue perfectly transparent specimens are often complex, costly, and time intensive, even though for many applications a slightly lower level of tissue transparency is sufficient and easily achieved with simpler and faster methods. Here, we present a microscope type that has been geared toward the imaging of semicleared tissue by combining multispot two-photon excitation with rolling shutter wide-field detection to image deep and fast inside semicleared mouse brain. We present a theoretical and experimental evaluation of the point spread function and contrast as a function of shutter size. Finally, we demonstrate microscope performance in fixed brain slices by imaging dendritic spines up to 400-MUm deep.

AB - This erratum corrects errors with the figure citations in https://doi.org/10.1117/1.JBO.23.1.016010. PMID- 29460512 TI - Coverage of multiple recessions using the tunnel technique and a collagen matrix in the maxilla or mandible: a 6-month study. AB - Multiple recession defects in the dentition of the patients are routinely encountered in clinical practice and as such present a challenge for clinicians. Periodontal plastic surgical procedures aim to restore both esthetics as function in periodontal tissues. The objective of this study was to evaluate and compare the clinical efficacy of using a tunnel technique with a collagen matrix to cover multiple recessions in the maxilla or mandible. Fourteen patients were enrolled in the study. Patients in the maxilla-group and mandible-group were treated with xenogeneic collagen matrix using the tunnel technique. Clinical recordings were obtained at baseline and after 3 and 6 months. The percentage of average recession coverage (ARC), the percentage rate of patients with complete coverage of all recessions (CRC-1) and the percentage rate of complete coverage of recession defects (CRC-2) were evaluated after 3 and 6 months after the surgery. Statistically significant differences were observed in every parameter except probing depth between the baseline values compared to the values 3 and 6 months after the procedure in both groups. The mean ARC 6 months after the procedure was 96.8% in the maxilla and 81.3% in the mandible. At 6 months after the procedure, a complete root coverage was obtained in 2 out of 9 patients and 31 out of 39 recessions (79%) in the maxilla and 0 out of 5 patients and 10 out of 20 recessions (50%) in the mandible. A collagen matrix combined with the tunnel technique led to a satisfactory ARC, CRC- 2 and resulted in an unsatisfactory CRC 1. PMID- 29460513 TI - The effect of gingival wall location on the marginal seal of class ii restorations prepared with a flowable bulk-fill resin-based composite. AB - SureFil SDR is a flowable resin-based composite that allows a single incremental bulk placement. The marginal seal of SureFil SDR at the gingival margins of class II restorations located apical to the cemento-enamel-junction (CEJ) has not been adequately evaluated compared to those located occlusal to the CEJ. Forty class II cavities were prepared in human molars. The gingival margins of 20 preparations were located 0.5 mm occlusal to the CEJ, and the other 20 preparations were located 0.5 mm apical to the CEJ. The cavities surfaces were bonded with XenoV dental adhesive and filled with SDR in one bulk increment up to 4 mm, after which they were covered with CeramX. The teeth were subjected to thermo-and load-cycling, and their gingival margins were exposed to 0.5% basic fuchsin solution. The specimens were sectioned mesio-distally and scored for microleakage. A Wilcoxon test for pairwise comparison was performed to determine significance. Dye penetration was observed in 30% of the 20 restorations with cavo-surface margins located occlusal to the CEJ and in 55% of the 20 restorations with cavo-surface margins located apical to the CEJ. The bulk-fill flowable resin base SureFil SDR with XenoV dental adhesive provided a better marginal seal in class II restorations with gingival margins above the CEJ compared to restorations with gingival margins below the CEJ. SDR should not be recommended for class II cavity preparations with gingival margins located below the CEJ. PMID- 29460514 TI - Rehabilitations with immediate loading of one-piece implants stabilized with intraoral welding. AB - The authors present an implant prosthesis procedure that uses screws on one-piece implants connected with a titanium pin at their abutment level and one supporter titanium bar in order to guarantee immediate stabilization. These can be implanted and fitted with customized temporary crowns in a single surgical procedure, restoring function and aesthetics and consenting recovery of the bone deficit with reduced healing times and limited patient discomfort. One-piece wide diameter titanium screw implants with thread measurements of 2.1 and 2.6 mm (smaller diameter) up to diameter of 4.5 mm with one abutment of 2.0 and 2.5 mm respectively, were positioned and splinted by intraoral welding. One-piece titanium implants were used together with a pin (needle) titanium implant as supporting structure to achieve deep stabilization. The Scialom-like pin has a diameter of 1.2 mm and it is long enough to reach deep cortical bone that is ?bicorticalism?. The One-piece implant is tightly connected to the needle implant by means of Mondani intra-oral welding technique. In severely atrophic anterior maxilla, the use of this method allows the immediate loading of a fixed resin prosthesis soon after surgery. These implants yielded satisfactory functional and aesthetic outcome in bone-deficient upper anterior sectors, without invasive regenerative procedures. The low invasiveness of this approach also consents rapid healing, reduced biological burden and greater patient benefit. PMID- 29460515 TI - The importance of occlusal trauma in the primary etiology of periodontal disease. AB - The presence of periodontal disease can be ascertained by clinical examination (redness, edema and probe depth, bleeding-on-probing). Occlusal adjustment can lead to a marked, stable improvement in periodontal health in terms of bacterial profile and clinical appearance, presumably by obviating tissue distress caused by occlusal dysfunction, thereby providing unfavorable conditions for bacterial growth. Therefore, occlusal trauma can be an essential indicator of the periodontal disease and, if not corrected, could lead to a relapse. PMID- 29460516 TI - Clinical applications of Natural Bone Morphoproteins in dentistry: a narrative review. AB - The need to restore bone loss in maxilla and mandible has led to find natural bone substitutes, such as fresh autogenous bone grafts. Fresh autogenous bone grafts (FABGs) have a remarkable capacity to induce new bone formation, a phenomenon called ?osteoinduction.? FABGs are useful in craniomaxillofacial and oral applications to restore bone deficiencies. The isolation of those proteins believed to be responsible for the osteoinductive activity of FABGs, namely Natural Bone Morphogenetic Proteins (NBMPs), led to a new era in bone regeneration. NBMPs have been approved for use in specific oral and maxillofacial applications. Clinical trials and studies of oral and craniofacial surgery have indicated that NBMPs can promote bone repair. Information about the biology, chemistry, and actions of NBMPs has called into question whether NBMPs would result in clinically useful bone induction and morphogenesis. Preclinical and specific clinical trials have indicated the efficacy of NBMPs either combined with autograft or compared with an autograft alone. In light of questions about potency and safety of NBMPs, however, additional high-level evidence is needed for specific clinical indications and appropriate patient populations that would benefit from their use. PMID- 29460517 TI - Peri-implant test is a proposal of a new procedure to prevent peri-implantitis and forensic claims. AB - Implant dentistry has become one of the most successful techniques for oral rehabilitation over the last 20 years. The success rate of implant oral rehabilitation is above 80% while peri-implant disease (PID) is the most important complication of implant dentistry. The main cause of PID is considered bacterial leakage at the implant-abutment connection of a two-piece implant system. Prevention and control of bacterial leakage at the implant-abutment connection is mandatory for reducing inflammation process around implants neck and achieving bone stability. Since bacteria leakage at implant-abutment connection level is the main cause of PID, a microbiological test should be important to identify bacteria that cause PID. According with the conclusion of workshop of the European Federation on Periodontology, a test that detects the most frequent bacterial species involved in the onset of PID (Actinobacillus actinomycetecomitans, Porphyromonas gengivalis, Tannnerella forsythia, Treponema denticola) should be used in clinical practice. In fact, PID progression depends on the typology, quantity and composition of bacterial flora in peri-implant pockets, so controlling PID onset and progression, is a keystone for preventing implant failures and consequently forensic conflicts. The effort to prevent PID and consequently assurance or forensic conflicts have become one of the main focal points of all dental professionals. Behind these efforts lie, above all, ethical but also economic reasons, as well as a desire to prevent PID, improving implant care quality and increasing the legal security of health care professionals themselves. Since the legal decisions in our society influence how we practice dentistry, especially in the fast-evolving field of implant dentistry, using diagnostic tools that will allow dentists to demonstrate that they have acted correctly in accordance with the knowledge of modern medicine, it is of great importance to defend themselves in the case of legal-legal disputes. PMID- 29460518 TI - Prevalence of HIV-related oral manifestations and their association with HAART and CD4+ T cell count: a review. AB - HIV infection is one of the major health problem of the last decades. This disease causes a chronic infection that can lead to acquired immunodeficiency syndrome (AIDS). According to the Global AIDS update, released in 2016 by HIV department of World Health Organization (WHO) and by the Joint United Nations Program on HIV/AIDS (UNAIDS), at the end of 2015, 36.7 million people were infected by HIV: 34.9 million of these were adults and 1.8 million were children under 15 years of age. The same report shows that during 2015, 2.1 million of new infection cases have occurred all over the world and about 1.1 million people have died for HIV. The aim of this short review is to up-date of the main HIV related oral manifestations and their correlation with HAART (Highly Active Antiretroviral Therapy) and CD4+ T-cell count. Despite that more than 20 years have elapsed, this classification still remains valid: even today, group 1 lesions are found in the majority of HIV-positive patients with oral manifestations. Group 1 includes the following conditions: oral candidiasis (pseudomembranous candidiasis, erythematous candidiasis, angle cheilitis), oral hairy leukoplakia, periodontal diseases (necrotizing gingivitis, necrotizing periodontitis, linear gingival erythema), Kaposi?s sarcoma, and non-Hodgkin?s lymphoma. Melanotic hyperpigmentation, HSV infection and HPV infection, which are included in group 2, are also common. Oral candidiasis, oral hairy leukoplakia, Kaposi?s sarcoma and HSV infection are the lesions that have seen the major drop in their incidence after the HAART introduction. The increase in CD4+ T-cell count is not significantly correlated to the decrease of every type of oral lesions, but it is statistically significant only in relation to oral candidiasis (p-value less than 0.001). Oral lesions are an important sign of immunodepression and with the introduction of HAART their incidence has strongly decreased, particularly in urban areas. Nevertheless, developing countries still have a high prevalence of these manifestations because of the persistence of many risk factors, like the difficulty to access treatment, poor oral hygiene, low socioeconomic status and late diagnosis. PMID- 29460519 TI - Human Papilloma Virus associated with oral cancer and preventive strategies: the role of vaccines. AB - The aim of this paper is to describe the efficacy of Human Papilloma Virus (HPV) vaccines for preventing oral cancer. A systematic review of the literature was conducted to describe the state of the art about HPV vaccines for preventing oral cancer. The aspects of prevention and control of infection by administering vaccines and the diffusion of sexual education campaigns are discussed also. In recent years there has been a growing interest in HPV in dentistry, suggesting a role of such a family of viruses in the development of oral cancers as well as of the uterine cervix. Even if the mass media have increasingly faced the problem, causing frequent alarming among patients, the dentist therefore needs a complete and up-to-date knowledge of this infectious condition that is one of the most common causes of sexually transmitted mucous membrane infections (eg genital, anal and oral). Recent studies about HPV infection are a basic requirement in order to promote the HPV vaccinations and patient?s health. PMID- 29460520 TI - Hypnotic approach during dental treatment: analysis of descriptive data of a case series. AB - Anxiety and worry are important components that affect the patient?s behaviour during dental sessions and influence the effectiveness of dental treatment. Psychological approach and hypnotic approach (HA) have in recent years assumed increasing prominence as effective treatment regimes. Dentists have used a number of methods in the management of dental phobic disorders through HA. However the efficacy of HA in controlling anxiety and worry is controversial. The aim of the present study is to describe the response of patient to HA during dental treatment. The study of the population consisted of 42 patients, these being 50% random sample of consecutive patients presenting to a private practise over an 8 year period. In 38 patients HA was induced. 4 patients were not susceptible to HA. There were 20 women (52.6%) and 18 men (47.3%) with a mean age of 47.2 years (range 30-69 years). At the end of dental sessions with HA all the patients were asked to answer the following questions: 1) Have you been hypnotized in the past? 2) Were you aware of dental applications of HA? 3) How do you evaluate the use of this technique in the field of dental care? 4) Do you think that you can use this procedure in the future too? The answers were as follows: question 1: 34 patients answered yes, 4 no; question 2: 34 answered yes, 4 no; question 3: the choice was between ?very useful?, ?useful?, ?Indifferent?, ?to avoid?. Twenty-nine patients indicated ?very useful?, and 9 ?useful?; question 4: the choice was between yes and no. All patients answered yes. This study adds further support to a growing body of evidence relating HA to a better compliance to dental treatment. The dental situation in particular lends itself to carefully controlled investigation providing further evidence to support a robust theory. PMID- 29460521 TI - HPV acting on E-cadherin, p53 and p16: literature review. AB - In addition to tobacco and alcohol consumption, the two main risk factors for oral squamous cell carcinoma (OSCC), recent studies have revealed infections with human papilloma virus (HPV) as an additional risk factor for OSCC development. In the field of head and neck malignancies, the prevalence of HPV infections in oropharyngeal cancer (OC) ranges in different studies up to 84%. While HPV infection is discussed as an independent risk factor in this region, its distinguished role in carcinogenesis of tumours localized to the oral cavity remains uncertain. A systematic literature search was performed using PubMed, Cochrane library, Science Direct, and the Internet search, with language restricted to English. The search included published studies which dealt with detection methods of HPV-related oral and oropharyngeal cancers and biomolecular studies, particularly regarding the compromising of p53 p16 and e-cadherin?s. P53 Tumour suppressor protein p53 has several functions that are related to maintaining genomic stability and inhibiting cell proliferation in response to DNA damage. For preventing neoplasia to occur, the most important of these functions are cessation of cell growth and induction of either apoptosis or senescence. P16 is a cellular protein involved in cell cycle regulation. It is a cyclin-dependent kinase 4 (CDK4) inhibitor, and is integral to Rb mediated regulation of G1-S phase of the cell cycle. P16 is expressed at a very low level in normal cell as Rb inhibits transcription of p16. Various detection methods ranging from immunohistochemistry (IHC) to molecular techniques have been used to determine the HPV status of HNSCC. E-cadherin, a 120 kDa Type I classical cadherin, is expressed primarily on epithelial cells. It is found on the surface of keratinocytesand Langerhans cells (LC) and E-cadherin mediated adhesion between these cell types is required for LC retention in the epidermis. It is also an important tumour suppressor protein: its loss or inactivation is associated with epithelial-to-mesenchymal transition (EMT), a process involving dedifferentiation, infiltration and metastasis of tumours. Oral carcinogenesis is a multi-factorial process involving socioeconomic, environmental and microbial factors leading to multistep changes. Smoking and tobacco exposure seems to modify the survival and recurrence of HPV positive tumours and should be considered in future trials for risk stratification of HPV positive patients. HPV associated oropharynx cancer represents a distinct clinical and biologic entity with many unresolved issues that will be investigated in future translational, clinical research. We need to further explore and understand why the disease occurs predominantly in males, and whether the natural history of oral HPV infection differences in men and women. PMID- 29460522 TI - Mechanical, chemical and biological aspects of titanium and titanium alloys in implant dentistry. AB - Implant dentistry has become a popular restorative option in clinical practice. Titanium and titanium alloys are the gold standard for endo-osseus dental implants production, thanks to their biocompatibility, resistance to corrosion and mechanical properties. The characteristics of the titanium implant surface seem to be particularly relevant in the early phase of osseointegration. Furthermore, the microstructure of implant surface can largely influence the bone remodelling at the level of the bone-implant surface. Recently, research has stated on the long-term of both survival and success rates of osseointegrated implants and mainly on biomechanical aspects, such as load distribution and biochemical and histological processes at the bone-implant interface. This short review reports recent knowledge on chemical and mechanical properties, biological aspects, innovations in preventing peri-implantitis, describing clinical applications and recent improvements of titanium dental implants. In addition, it highlights current knowledge about a new implant coating that has been demonstrated to reduce the number of initially adhering bacteria and peri implantitis. PMID- 29460523 TI - Depression and distress in burning mouth syndrome: A case control study. AB - To compare the results of psychometric tests in patients with BMS and controls, participants were tested for depression, anxiety, fatigue and distress. Patients with BMS had noticeably higher scores for depression, fatigue and distress, compared to controls. Depression and distress were significantly correlated with the burning symptom. Moreover, distress and burning symptoms proved to be interdependent. Depression seems to play a specific role in BMS. Burning symptoms affect quality of life of patients and they could be a predictor of distress. PMID- 29460524 TI - Psychiatric disorders in oral lichen planus: a preliminary case control study. AB - The aim of this study was to evaluate the prevalence of psychiatric symptoms in patients with oral lichen planus (OLP) compared to a control group. Eleven patients (mean age 65.2 years-old), with diagnosis of OLP and 13 controls (mean age 64.8 years-old) underwent a psychiatric evaluation with five psychometric scales: Visual Analogue Scale (VAS), Hamilton Rating Scale for Depression (HAM D), State-Trait Anxiety Inventory (STAI 1-2), Distress Thermometer (DT) and Brief Fatigue Inventory (BFI). Seventy-three % of OLP group presented a VAS score of mild type; 9% had depressive symptoms; 100% of the sample had a score above the cut-off for state and trait anxiety; 45% presented Distress (36% moderate type). However, no statistical difference was found in comparison with the control group. In this study, there was no difference in these parameters between the OLP group and the control group. Perhaps, a larger cohort of patients could give different results. PMID- 29460525 TI - How social media meet patients? questions: YouTube? review for children oral thrush. AB - YouTube? is increasingly being used by patients to obtain health-related information. No studies have evaluated the content of YouTube? videos on children oral thrush. The aim of this work is to examine the quality of information offered by this platform about oral thrush in children. Searching term ?oral thrush in children? (OTC) displayed a total of 2.790 results. Of the top 60 videos analyzed, 27 were excluded. The main source of upload was from generalist information YouTube(r) channels (GC) followed by healthcare professionals (HP), individual users (IU), and healthcare information channels (HC); usefulness of videos is successfully correlated with the number of visualization, number of likes and viewing rate and was interdependent with the number of visualizations, number of likes and VR. However, videos on the oral thrush do not have satisfactory quality information. HP themselves, along with HC, do not seem to provide more appropriate information on COT, than GC or IU. PMID- 29460526 TI - Analysis of saliva samples in patients with Prader-Willi syndrome. AB - Patients affected by Prader-Willi Syndrome (PWS) usually show orofacial dysfunction, poor oral hygiene, severe tooth wear, generalized caries and thick sticky saliva. The aim of this study was to evaluate molecular/ionic changings in PWS patients compared to controls, as well as unstimulated salivary flow rate (SFR); 7 patients with a mean age of 20.0+/-5.45 years were enrolled in the study group (PWS group) and 5 patients with a mean age of 22.6+/-3.05 years, in the control group. Results showed a greater Na+ (p=0.003), Cl+ (p=0.004) and P (p=0.001) concentration in saliva of PWS group as well as a greater concentration of secretory IgA (p=0.003) with a reduction of SFR (p=0.004) compared to controls. A Spearman?s analysis (based on the SFR of both groups) revealed an inverse correlation with Na (rho=-0.747), Cl (rho=-0.723), P (rho=-0.637) and sIgA (rho=-0.707) concentration and SFR, when linear regression model was performed only P and SFR were interdependent (beta=-0.748; p=0.005).

The major source of upload was from healthcare information channels (HC-41,38%), followed by individual users (HP-25.59%), healthcare professionals (IU-17.24%) and generalist information channels (HC-13.78%); 20.69% of them deal with predisposing factors, and related pathologies, the majority of these propose home remedies (60.72%) rather than topical analgesic drugs (21.43%), antimicrobials (7.14%) and topical steroids (3.57). Most of the videos analyzed were slightly useful (68.97%). Information about mouth sores in children on YouTube? was poor regardless of the upload source. Analyzing health content on social platforms is a starting point for providing greater quality of health-related information. PMID- 29460529 TI - Systemic and topical photodynamic therapy (PDT) on oral mucosa lesions: an overview. AB - Photodynamic Therapy (PDT) is a minimally invasive treatment that has shown promising results in treating preneoplasticlesions. PDT reckons on the administration of a drug (photosensitizer), which can be used in a topical or systemic form. Photodynamic therapy has been successfully used in the management of a variety of pathologies from different anatomical sites, including the head, neck, brain and lungs, hepatobiliary tree and other gastrointestinal and urological pathologies, skin, gynaecological conditions and in vascular anomalies. Starting from these same considerations, PDT has also been adopted for oral malignant and premalignant lesions? treatment, and should be kept under investigation as a promising therapeutic management of leukoplakia and preneoplastic lesions of the oral cavity. PMID- 29460530 TI - Oral-facial-digital syndrome (OFD): 31-year follow-up management and monitoring. AB - Orofaciodigital syndrome (OFD) is a group of hereditary disorders identified by malformations of the mouth (oris), face (facies), hands and feet (digitus=finger and toe). Although there are several different types reported in the literature, there is a great overlap in their clinical presentation. The full spectrum of all disorders due to OFD is not yet fully understood, since each patient shows variations in the expression of the syndrome. In the oral cavity, teeth are often affected by various alterations, such as dental caries, abnormal teeth, enamel hypoplasia, supernumerary teeth and dental agenesis. Treatment of a syndromic patient with a complex picture showing conditions such as palatine fissures and a severe hypodontia involves a multidisciplinary approach and a careful periodical follow-up. PMID- 29460531 TI - Telescopic overdenture on natural teeth: prosthetic rehabilitation on (OFD) syndromic patient and a review on available literature. AB - Orofaciodigital syndromes (OFD) are rare genetical disorders characterized by malformations of the mouth (oris), face (facies), hands and feet (digitus = finger, toe). It is still impossible to fully understand the whole spectrum of all dysfunctions due to OFD, since the expressions of the syndrome vary in each patient. There are various alterations, thoroughly described in literature that can affect the oral cavity such as dental caries, abnormal teeth, enamel hypoplasia, supernumerary teeth and dental agenesis. A syndromic patient with a complex picture showing conditions such as palatine fissures and a severe hypodontia has to be treated using a multidisciplinary approach, and in particular, needs a prosthetic rehabilitation for the restoration of missing dental elements in the arch. PMID- 29460532 TI - Lichen planus: molecular pathway and clinical implications in oral disorders. AB - Stem cells play a role in many mucosal disorders characterised by abnormal proliferation and differentiation of keratinocytes, such as oral lichen planus (OLP). In OLP there were changes in stem cell markers as component of integrin complexes alpha6 and beta1 integrin increased along with increase of melanoma associated chondroitin sulphate proteoglycan (MCSP) and decreased of notch1 (N1) and keratin 15 (K15). Stem cell marker expression may be altered by pathological signalling in these lesions. Cadherins are transmembrane receptors that provide cell-cell contact and communication function through calcium-dependent homophilic and heterophilic interactions. In actively diseased areas of OLP lesions, basal keratinocytes downregulate CD40 and were focally E-cadherin-negative, in contrast to non-diseased areas and normal oral mucosa. This loss of E-cadherin expression may contribute to epithelial basal cell destruction and T-cell migration into the epithelial compartment in OLP. In addition, Growth factor pathways as a role in OLP and has been analyzed in this review. PMID- 29460533 TI - Colonization of Legionella spp. In dental unit waterlines. AB - Legionella spp. are ubiquitous in aquatic habitats and water distribution systems, including dental unit waterlines. Surveys have shown that the percentage of samples taken at different dental sites that were positive for Legionella spp. were highly variable and ranged from 0% to 100%. Cultivation is the principal approach to evaluating bacterial contamination employed in the past, but applying this approach to testing for Legionella spp. may result in false-negative data or underestimated bacterial counts. PCR and direct fluorescent counts can detect viable non-cultivable bacteria, which are not counted by plating procedures. Legionella spp., commonly form such viable non-culturable cells and it is likely that they contribute to the difference between plate count results and those of PCR and fluorescent-antibody detection. However, studies have shown that Legionella is present in the municipal water source in spite of the current filtration and chlorination procedures. Once Legionella reaches the building water system, it settles down into a biofilm layer of stagnant water. By means of this layer, Legionella can protect itself from antimicrobial agents and then multiply. Dental unit waterlines may be contaminated with opportunistic bacteria. The water quality in the dental units should be controlled to eliminate opportunistic pathogens and to provide water for dental treatment that meets public health standards for potable water. PMID- 29460534 TI - Focus on periodontal disease and development of endocarditis. AB - : Infective endocarditis is a devastating disease with high morbidity and mortality. The link to oral bacteria has been known for many decades and has caused ongoing concern for dentists, patients and cardiologists. The microbiota of the mouth is extremely diverse and more than 700 bacterial species have been detected. Half of them are uncultivable so far. Oral microbiota is not uniform, specific sites exist in the mouth such as tongue, palate, cheek, teeth and periodontal pockets that have their own microbiota. Factors involved in the development of a bacterial endocarditis are difficult to define but a vulnerable surface (i.e. a damaged endocardium) and a high bacterial load in the blood seems to be decisive. The cause of microorganisms, in 90% of cases, are staphylococcus, streptococcus and enterococcus. Oral streptococci belong to viridans group (streptococcus mutans and streptococcus sanguis). As they are part of dental plaque, they could enter the bloodstream causing bacteraemia through daily habits like chewing or tooth brushing. Effective treatment of periodontal infections is important to reduce local inflammation and bacteraemia. In addition, poor periodontal health appears to increase the risk of cardiovascular disease, pulmonary disease, and preterm and low birth weight. CONCLUSIONS: Long-standing oral disease prevention protocols reduce the risk of developing periodontal disease. Data suggests that methods used to prevent cases of IE that originate from oral bacteria should focus on improving oral hygiene and reducing or eliminating gingivitis, which should reduce the incidence of bacteraemia after tooth-brushing and the need to extract teeth owing to periodontal disease and caries. PMID- 29460535 TI - Analyze my face. AB - Plastic surgery is gaining more and more popularity, while stigma and popular myths about it are gradually decreasing. Analyze My Face conjunctly deals with the two main problems of facial plastic surgery: the excessive rate of dissatisfaction, which results in high revision requests and negative psychological side-effects and the ?diagnosis by procedure? approach, which leads to erroneous measurements. This new and innovative method of Digital Facial Analysis is a direct non-expensive online service that provides professional and documented in-depth consultation to patients before they decide to undergo any type of facial intervention. The paper thoroughly explains the scientific method with which professionals provide customers with a facial assessment based on specific parameters which will be discussed (height, width, proportions, direction of facial growth, the way they assess each facial area in detail (eyes, mouth, cartilage), and the motivations for which they suggest to correct eventual defects through precise measurements, indicators and suggested interventions. Long-term evaluation of stability of surgical results and patient satisfaction achieved with digital facial analysis has not yet been established and needs further research. However, it is important to underline that the AMF approach tends to consider exclusively possible and feasible procedures that do not compromise functionality and that do not put patients in danger of serious damage. Problems or deformities that cannot be treated are always indicated. AMF aims to maximize professionality by giving practitioners an additional tool to aid their work, give unbiased opinions and look at the overall picture. It also aims to help patients by soothing their way into the complicated world of aesthetic surgery. PMID- 29460536 TI - Traumatic and surgical scars: successful treatment with a 1,565nm erbium-glass NAFL combined with IPL. AB - Scars are a very common condition of the general population and can have a profound impact on the psyche of the patient such as low self-esteem and feelings of psychosocial isolation. Various therapeutic approaches have been proposed for improving the clinical appearance of scars. Fractional mode of ablative and non ablative lasers has become a novel strategy for the treatment of scars. A total of 43 patients (Fitzpatrick skin type II to IV), clinically diagnosed of surgical and post-traumatic scars from January 2015 to December 2016, were treated. Each treatment comprised of several passes over the scars with different devices, using a 1.565nm scanned erbium-doped fiber NAFL and an IPL. All patients noted subjective improvement in cosmesis and functionality after treatment, also with a decreased pain and an increased mobility on the underlying plans. Numerous therapeutic strategies for traumatic and surgical scars have been suggested to date, but no consistent treatment modality has been established yet. In our study, we have shown that there was a significant collagen remodelling with decrease of scar vascularity and significant improvement of pliability of scar after combined treatment with non-ablative fractional resurfacing and IPL resulting in a remarkable improvement in scar vascularity, pigmentation and height. PMID- 29460537 TI - Pre-treatment with berberine enhances effect of 5-fluorouracil and cisplatin in HEP2 laryngeal cancer cell line. AB - Larynx squamous cell carcinoma represents one of the most common head and neck cancers in the world. Herbal drugs are popularly emerging as complementary and alternative therapies in cancer because of their cost effectiveness and minimal side effects. The present study was undertaken to explore the anti-tumor potential of berberine, an isoquinolone present in the extract of Tinospora cordifolia in HEP2 human laryngeal cancer cell line. Besides, it was aimed to investigate whether berberine could enhance the anti-cancer effect of 5 fluorouracil and cisplatin in HEP2. Our data seem to support a role for berberine in decreasing the expression of genes usually seen overexpressed in larynx squamous cell carcinoma and involved in pathways such as those of cell cycle and regulation, differentiation, and epithelial-mesenchymal transition. Moreover, a down regulation of these genes caused by cisplatin or 5-fluorouracil, treatment of election in laryngeal cancers was enhanced by a 4h pre-treatment with berberine. PMID- 29460539 TI - Human polyomavirus in tonsillar microbiota of an Afghan population group. AB - Some studies have evidenced the role of human polyomaviruses in head and neck squamous cell carcinoma. BK, JC and SV40 human polyoma viruses are widely recognized as etiological agents associated with malignancies. The aim of this study was to analyse the prevalence of BK, IC and SV40 in tonsillar microbiota in a group of Afghan volunteers. A sample of the tonsillar microbiota was taken from a single site using a sterile oral swab paper stick. A fixed volume of purified DNA from each sample was tested by quantitative real-time polymerase chain reactions to evaluate the number of human cells and the number of viral genomes in each sample. The cell number was evaluated via the quantification of a single copy genomic sequence, which is located in the HMBS locus. The median analyzed cell number in each reaction was 4343 (interquartile range 2074-8470). SV40 was never detected, while prevalence rate was 0.11 (C.I. 0.06-0.20) for BK and 0.10 (C.I. 0.05-0.19) for JC. Further studies are necessary to clarify whether polyomaviruses can be considered a risk factor of oral, oropharyngeal and laryngeal malignancies. PMID- 29460538 TI - Detection of endocarditis bacteria in tonsillar mucosa of Afghan population. AB - Endocarditis is a cardiovascular disease caused by the inflammation of the inner tissues of the heart, the endocardium, usually of the valves. Bacteraemia is essential in the development of endocarditis, and there are some findings that the main pathogens of endocarditis are viridans group streptococci: Streptococcus oralis, Streptococcus sanguinis, and Enterococcus faecalis. There is strong evidence that endocarditis bacteria are present in the tonsillar microbiota, so that tonsillar infection is associated with an increased risk of endocarditis. The aim of this manuscript is to investigate the presence of the main pathogens of endocarditis in tonsillar microbiota of an Afghan population group. A sample of 80 tonsil swabs were analyzed by quantitative real time PCR to detect endocarditis pathogens and an estimation of the total bacterial load. The median bacterial load in PCR reaction was 1.4x106 (interquartile range 4,7x105 - 2,9x106). Three species, S. Oralis, S. Sanguinis, and E. Faecalis were found in large amounts in all specimens. On the other hand, S. Mitis was never detected. The S. Aureus was found in 3 samples with a prevalence of 0.04 (C.I. 0.01-0.10). The S. Mutans was found in 33 samples with a prevalence of 0.41 (C.I. 0.31-0.52). Endocarditis bacteria has been found into the tonsillar microbiota, so there is sufficient evidence to justify that the oral cavity is a reservoir of endocarditis bacteria that can have a significant impact on the cardiovascular function. PMID- 29460540 TI - Human papilloma virus in the tonsillar microbiota of an Afghan population group. AB - Cancer of the oral cavity is known to have a diverse aetiology that includes infectious agents. Human papilloma virus has been found to be associated with several types of human cancer, inclusive of cervical, vulvar, vaginal, penile, anal, and cancer of tonsil. The aim of this manuscript is to investigate the presence of human papilloma virus in tonsillar microbiota of an Afghan population group. A sample of the tonsillar microbiota was collected by oral swab paper stick from 80 healthy donors. The sample was investigated for the presence of high-risk human papillomavirus types 16, 18, 31 and 45 by real time PCR. Eight samples produced some positive endpoint signals for human papillomaviruses. The human papillomavirus 31 was the unique papillomavirus detected; its calculated prevalence rate was 0.10 (C.I. 0.05-0.19). However, the viral load was always very low, in the order of 10-3 viral genomes per cell. The high prevalence of high-risk human papillomavirus in healthy population suggest a need for further investigation on virus spreading and supports the development of vaccination strategies. PMID- 29460541 TI - Radiosurgery-assisted gingival displacement: a proof of concept technique to enhance the efficiency of intraoral digital impression. AB - Nowadays, an increasing number of dentists are using intraoral scanners (IOS) in their daily practice as an alternative to conventional impression taking. One of the main concerns is related to the capability of scanning the subgingival anatomy of the die, usually very challenging due to the limited operative field and the presence of oral fluids. The radiosurgery assisted gingival displacement technique (RAGD) may enhance the intraoral optical scanning of the finish line and neighbor tooth anatomy. The contour of the interim prosthesis is used to drive the tip of radiosurgery electrode along the tooth surface and open selectively the gingival crevice with a prosthetically-driven and minimally invasive approach. The clinical implication of this technique is related to increasing the efficiency and accuracy of the digital impression technique in the critical zone of the prosthetic shoulder. PMID- 29460542 TI - Temporomandibular joint and related structures: anatomical and Histological aspects. AB - In literature, there is no unanimous agreement about the anatomical and functional characteristics of the temporomandibular joint (TMJ) and its components. The aim of this work is to increase the knowledge about components of the temporomandibular joint, starting from the revision of classical anatomy, through macroscopic and microscopic study, 20 samples of human dissected temporomandibular joints. PMID- 29460543 TI - Anatomic relationship between temporomandibular joint and middle ear. AB - The present study was designed to identify a relationship between temporomandibular joint and tympanic cavity and potentially justify the possible clinical correlations between these two anatomical entities. For this reason the authors conducted an anatomic-pathological study about the temporomandibular joint (TMJ) and the neighboring anatomical areas of the middle ear by autopsy finds of human adults. PMID- 29460544 TI - TMJ?s capsule histological and macroscopical study: relationship between ligamentous laxity and TMI dysfunctions.

PMID- 29460545 TI - Hyperbaric oxygen therapy (HBOT) and peridontal health. AB - This study has tested the effects of hyperbaric oxygen in periodontal structures in agreement with the theories supported by literature research. Eight patients, from 30 to 50 years-of-age, were tested with pure oxygen inhalation, at the 2.5 ATA absolute pressure. Main approved tests of periodontal health were evaluated before and after HBOT?s cycles. The results in all patients treated with HBOT, have founded clear improvement of clinical and instrumental parameters. PMID- 29460546 TI - FDPS finish line design and tooth preparation technique. AB - The purpose of this research is to perform and verify the ?modified 50 degrees preparation? suggested by the authors. This procedure was performed with a scrupulous standardization of the tooth?s preparation and then of the laboratory techniques to produce a metal-ceramic crown, and the same for the crown cementation technique of on the preparation of the original sample. After the esthetic evaluations, the obtained sample was included in EPON resin and sectioned in the lingual-vestibular sense. The sections were then observed with an optical microscope in different magnifications for the final evaluations. The geometric design proposed presents the advantages of two great preparation techniques: 50 degrees preparation and circumferential shoulder. The 50 degrees bevel designed in first phase of preparation and the second phase of the circumferential 27 degrees shoulder, together allowed to satisfy the following requirements: aesthetic, marginal accuracy, periodontal compliance, conservation and stability. However, this type of prosthetic preparation is not the only one, but it is one of the marginal designs in prosthetic dentistry. PMID- 29460547 TI - Zinc plus octenidine: a new formulation for treating periodontal pathogens. A single blind study. AB - Periodontal treatment has the aim to reduce oral infection, and prevent the progression of the disease. The potential benefits of new chemical devices for periodontal therapy, include improved patient compliance, an easier access to periodontal pocket and a lower dosage of antimicrobial agent. The objective of this study was to explore the efficacy of a chemical device containing zinc and octenidine in the treatment of chronic periodontitis in adult patients. Ten patients with a diagnosis of chronic periodontitis (20 localized chronic periodontitis sites) in the age group of 35 to 55 were selected. None of these patients received any surgical or non-surgical periodontal therapy and demonstrated radiographic evidence of moderate bone loss. The chemical device zinc plus octenedine was used by each patient after daily oral hygiene. Microbial analysis were analyzed at baseline and on the 15th day. After the treatment, a remarkable decrease in bacteria amount, both for some species and for the total count was observed in the study group. Specifically T. Forsythia and T. Denticola were eradicated whereas Total Bacteria Loading and Fusobacterium Nucleatum showed a reduction of 38% and 55%, respectively. Our study demonstrated the efficacy of the new chemical device containing zinc and octenidine in a sustained release drug delivery system in the management of moderate to severe chronic periodontitis. PMID- 29460548 TI - The role of zinc plus octenidine in the regulation of gene expression: an in vitro study. AB - Zinc was known in ancient times, and is diffused in the environment. The potential benefits offered by zinc supplementary therapy have been demonstrated in numerous clinical trials using oral or topical zinc products. The benefit of zinc can be in principle increased through association with other actives. The aim of this study is to evaluate the effect on primary human gingival fibroblast cell of a new formulation containing zinc and octenidine cations. Human gingival fibroblast cells were obtained from three healthy patients (14-year-old man, 15 year-old woman and 20-year-old man) during extraction of teeth. The gene expression of 14 genes (ELANE, FN1, FBN, ITGA1, HAS1, ELN, DSP, ITGB1, HYAL1,TGFB1, TGFB2, TGFB3, TGFBR1 and TGFBR2) was investigated in HGF cell culture treated with 80MUm of Octenidine, 1000MUm of Zinc, 80MUm Octenidine + Zinc solution and the medium alone at 30 min. Prestoblue? data showed that as the active concentration increases (Octenidine, Zinc and Octenidine + Zinc) the percentage of cell vitality compared to that of untreated cells decrease. In this study, no statistically significant gene expression was observed between cells, treated with difference substances, and control cells. Our results points out that zinc plus octenidine shows a positive potential in periodontal disease treatment. PMID- 29460549 TI - IgM and IgA enriched polyclonal immunoglobulins reduce short term mortality in extremely low birth weight infants (ELBW) with sepsis: a retrospective cohort study. AB - BACKGROUND: Immunoglobulin supplementation is a debated strategy in fighting sepsis. We evaluated a polyclonal IgM and IgA enriched immunoglobulin (IgMeIVIG) preparation in reducing the short term mortality in extremely low birth weight neonates (ELBW) with proven infection. METHODS: ELBW infants born from January 2008 to December 2014 were eligible for this retrospective casecontrol analysis if they were symptomatic and had a positive blood culture after 72hours of life. Patients received antibiotic treatment with or without IgMeIVIG (intravenously,250mg/kg/day for 3 days) within the 24 hours from clinical suspicion as per indication of the attending physician. Shortterm (7 and 21 days) mortality was the study primary outcome while secondary outcomes were: mortality at discharge, intraventricular hemorrhage, necrotizing enterocolitis, bronchopulmonary dysplasia, periventricular leukomalacia, and retinopathy of prematurity. RESULTS: Each group was composed by thirtynine infants. Both groups were similar for antenatal steroids, mode of delivery, birth weight, gestational age and SNAPII score as indicator of disease severity. Infants receiving IgMeIVIG had a significantly lower shortterm mortality compared with neonates receiving antibiotics alone: 6/39 (15%) vs 14/39 (36%); p = 0.038. No differences in other outcomes were found. CONCLUSIONS: This study shows that IgMeIVIG may have a role as adjuvant therapy in ELBW infants with proven sepsis. We warrant future prospective, blinded RCT studies where IgMeIVIG can be consistently used if needed throughout the NICU admission in ELBW septic neonates to appropriately evaluate its effect on mortality at discharge. PMID- 29460550 TI - Prevalence of overweight and obesity among Kuwaiti adolescents and associations with socioeconomic indicators: the study of health and activity among adolescents in Kuwait. AB - BACKGROUND: Kuwait is one of the Arab countries with the highest prevalence of overweight or obesity. However, few studies have described the prevalence of obesity in this country. AIM: To describe the prevalence of overweight and obesity among Kuwaiti adolescents; and to examine the association of overweight and obesity status with familial socioeconomic status (SES). METHODS: Cross sectional data from 591 adolescent students (47% boys, median age: 16 years) from the Study of Health and Activity among Adolescents in Kuwait in 2012 and 2013. Body weight status was determined using the International Obesity Task Force (IOTF) body mass index standards. SES was based on parental education. Odds ratio for overweight and obesity were calculated using multiple logistic regression. RESULTS: In our study, over half of the adolescents were overweight or obese 54.3% (95% CI: 49.9-58.4). The prevalence of overweight (including obesity) was higher in boys (59.8%, 54.3- 66.3) than girls (49.2%, 43.5-54.8). No association between parental education and the risk of overweight/obesity was found. CONCLUSIONS: There is an alarmingly high rate of overweight/obesity among Kuwaiti adolescents, but we did not find evidence of a social gradient in obesity risk. Urgent actions are needed to reverse this epidemic across all social groups. PMID- 29460551 TI - Psychopathological risk in a sample of immigrant preadolescents in Italy. AB - BACKGROUND: Aim of the study is to collect information about emotional features in a sample of immigrant preadolescents in order to identify traits of emotional fragility or psychopathological risk factors. METHODS: The sample consists of 1206 preadolescents (180 immigrants, 1026 Italian natives) attending the third year of the middle schools. In order to assess anxiety levels and the presence of depressive symptoms the Self- Administered Psychiatric Scale (SAFA-A) and the Children's Depression Inventory (CDI) were administered. Coping strategies and behavior problems were evaluated by the Coping Inventory for Stressful Situation (CISS) and the Youth Self Report scale (YRS). All teachers filled out the Teacher's Report Form (TRF). Parents were asked to fill out a form on social demographic features and the Multidimensional Scale of Perceived Social Support (MSPSS). RESULTS: Immigration resulted a risk factor for development of anxiety (OR=0,702), depression (OR=0,644), internalizing problems (OR=0,685), behavior problems (OR=0,622) and total problems (OR=0,719). Teachers observed more behavior problems and lower competences in immigrants than natives. Immigrants relied significantly more often on emotion-oriented coping strategies to resolve stressful situation than natives (p=0,045). Analyzing the immigrants sample, second generation children reported significantly higher levels in total competence (school, activity and relationship) than first generation ones (p=<00,1); on the contrary there were no significant differences between the two groups concerning other behavioral and emotional problems or the preferred coping style. Natives' families reported significantly higher levels of perceived support than immigrant ones. CONCLUSIONS: Our findings confirms the hypothesis that preadolescent immigrants are more at risk for psychopathological risk factors than native peers.

PMID- 29460553 TI - Can early physical therapy positively affect the onset of independent walking in infants with Down syndrome? A retrospective cohort study. AB - BACKGROUND: The development of both gross and fine motor skills in a child with Down syndrome is generally delayed. The most seriously affected stage is the achievement of independent walking ability, which influences the onset of all following motor and cognityive skills. The study objectives were (a) to assess the time taken to achieve independent walking ability in a cohort of children with Down syndrome, (b) to examine differences in walking onset by patient characteristics, (c) to verify the effect of early physical therapy (Neurodevelopmental Treatment on the basis of Bobath Concept practised within the first months of life) in the achievement of that skill. METHODS: A retrospective study was carried out on a cohort of 86 children with Down Syndrome. The knowledge of the exact age of walking onset and information about comorobities and rehabilitation practised since birth were the eligibility criteria. RESULTS: The average age at which walking began in the sample was 26 months (Standard Deviation = 9.66). Some patient characteristics proved to be related negatively to the walking onset: gender male, trisomy 21, improved joint ligamentous laxity. When practised, early physical therapy was able to contrast the delay in walking. CONCLUSIONS: NDT-Bobath is a well-known and valid instrument for a child with Down syndrome to attain his highest possible psychomotor functioning level. This study pointed out for the first time ever its capability to contrast the delay on walking onset, which can influences positively the development of the following motor and cognitive skills.

PMID- 29460555 TI - [Editorial.Reflect on the past to project us to the future]. PMID- 29460556 TI - [Clinical training and perception of its effects on the first novice nurse work experience: a phenomenological study]. AB - AIM: The aim of this study was investigating, analysing and evaluating which aspects of the clinical training would be most useful to newly degreed nurses in carrying out their work activities post-graduation, based on their experience. METHODS: This is a phenomenological qualitative study, with semi-structured, face-to-face, in depth interviews. We used purposive sample. Recruiting of interviewees stopped at achievement of data saturation. Interviews were all audio recorded and transcribed verbatim and analysed in double blind, in order to identify the main themes that emerged. The Van Kaam method was used to analyse interview content. RESULTS: Fourteen nurses, just graduated from Milan University, were involved in the study. Five themes emerged: the relation between theory-practice and the development of clinical thinking, the "time factor" in clinical training duration, the clinical nurse teacher as a professional model, the first days as a nurse: beautiful, traumatic and with loads of responsibility, and finally improvement strategies for a continuously evolving profession. CONCLUSION: Clinical training is confirmed as a key moment in the link of theory with practice and to infuse the newly qualified professional with the necessary autonomy, self-confidence and practical knowledge. Novice nurses highlighted many positive aspects of their training obtained by means of the clinical training experience, but also that they need time in order to develop confidence and learn to handle responsibility; in this respect, the clinical nurse teacher is seen as a fundamental figure. PMID- 29460557 TI - [Errors in Medicine: perceptions of nursing students in Rome]. AB - INTRODUCTION: The error in medicine has long been discussed in scientific debates. The purpose of this study is to evaluate the degree knowledge, attitude and behavior of students in Nursing for the failure in the health sector. METHODS: It was administered to 231 students of Nursing of the Sapienza University of Rome (171 females and 60 males), aged between 21 and 45 years, a structured questionnaire in three questions that explore the experiences and opinions about the errors found in medical practice, the causes underlying them and the mistakes that should never be committed. Data were collected, stratified by sex, age, marital status, and analyzed using the chi2 test. Significance was set at p<=0.05. RESULTS: The 5 errors found more frequently in clinical practice by the students were the following: Errors that favors the onset of hospital infections (58.9%); Non adherence to protocols (50.2%); Patient care (45.9%); Errors due to the administration of therapies and drugs (45.9%); Errors relating to the execution of withdrawals (35.9%). The five cases considered most frequently responsible for such errors were: the rush (70.1%), followed by neglect / superficial (55%); disorganization (51.5%); not hygienically / infertility (50.6%) and inattention (42.9%). With regard to the errors that you should never commit, students have shown more frequently: the errors of administration of therapies / medications (69.3%); errors of prescription therapies / medications (58.9%); errors related to surgery (52.8%); the exchange of patient or misidentification of the patient (50.6%); errors that favor the occurrence of hospital infections (48.1%). CONCLUSIONS: The results of this study shows the importance of a culture of error in medicine, also as part of undergraduate education, in order to train and educate future health professionals to this issue in order to promoting patient safety and quality of health. PMID- 29460558 TI - [The impact of Reiki on side effects in patients with head-neck neoplasia undergoing radiotherapy: a pilot study]. AB - BACKGROUND: Cancer patients often report symptoms related to therapeutic treatment, whose management is based on traditional medicine. In recent years, however, there has been growing interest towards adopting some form of complementary medicine, among these, Reiki. The aim of this study is to evaluate how this type of discipline can contribute to managing radiotherapy-related symptoms in patients with head and neck cancer. METHOD: The study was performed in the Radiotherapy Department at the Regina Elena National Cancer Institute in Rome. To assess QoL, the FACT-H N questionnaire was used, while the CTCAE Scale was adopted to evaluate mucositis, cutaneous toxicity and salivation. RESULTS: 10.5% of patients were reported to experience strong pain in the fifth week, compared to 21.1% of patients in the previous week; a degree of mucositis equal to G3 was also found in 15.5% of cases according to the clinical evaluation, as well as in 10.5% of patients according to the functional one. Only one case (5.3%) of grade 3 cutaneous toxicity was registered. CONCLUSION: The study shows how the Reiki treatment benefits patients in most cases, with both psychological support to help deal with the therapeutic process together with integrated support towards pain therapy. PMID- 29460559 TI - [How the bed rest period and the posture assumed by the patient post lumbar puncture caninfluence the onset of complications: a rapid evidence assessment]. AB - AIM: To identify how the bed rest period and the posture assumed by the patient after lumbar puncture can influence the onset of complications, and which nursing interventions to adopt in order to reduce the complications. METHOD: A rapid assessment review was performed and the electronic databases PubMed, CINAHL, and the Cochrane Central Register of Controlled Trials were searched between 2001 and 2015. RESULTS: Initially, 407 studies were retrieved, and 5 of these publications were considered to be eligible for the purpose of the study,4 comparing different periods of bed rest and 1 comparing patients position. Headache, nausea, vomiting and other symptoms, do not seem to reduce with a 24 hours longer bed rest. There is a lack of evidence on the effectiveness of early mobilization, as well as on the effects of different postures after the procedure performed to reduce the incidence of complications. Only a statistically significant gender difference in the onset of the headache was found: women seem to be more at risk. The selected studies showed a medium-low methodological quality and a high heterogeneity in the systems used to measure the symptoms, in the features and dimensions of the investigated populations. CONCLUSIONS: Currently available data do not permit to identify care interventions related to effective bed rest period based on scientific evidences in order to prevent post rachicentesis complications. It is therefore considered necessary to conduct further experimental and observational studies, with a high methodological rigor in order to maximize the effectiveness of nursing care. PMID- 29460560 TI - [Isolation precautions in multi drug resistent infections and nursing workload in a general intensive care unit]. AB - BACKGROUND: Critically ill patients in ICU are exposed to high risk of hospital acquired infections. In recent years, the multi drug resistant microorganisms (MDR) represent the most worrying epidemiological problem. AIM: The aim of this study is to evaluate the relationship between isolation precautions and nursing workload. METHODS: We studied patients who had an infection by MDR, subject to isolation precautions, and measured their NAS score during stay in ICU. MDR infections of studied patients were: Acinetobacter Baumannii, Klebsiella KPC, MRSA, Pseudomonas, Escherichia coli, Serratia marcescens e Clostridium difficile. Isolation precutions wer identified by color code (green, yellow, red). RESULTS: We studied 44 patients during the year 2012. NAS average was 81.54 +/- 10.25. NAS average for "green code" patients was 81.25 +/- 22.12, for "yellow code" patients was 82.57 +/- 11.25 and for "red code" patients was 79.06 +/- 29.12. DISCUSSION: the presence of isolation precautions seems to have no influence on nursing workload measured by NAS score, except for Acinetobacter Baumannii infection. Further research will be needed for better evaluation of this topic. PMID- 29460561 TI - Modified Moral Distress Scale (MDS-11): Validation Study Among Italian Nurses. AB - BACKGROUND: Moral distress (MD) has significant implications on individual and organizational health. However there is a lack of an instrument to assess it among Italian nurses. AIM: The main aim of this study was to validate a brief instrument to assess MD, developed from the Corley's Moral Distress Scale (MDS). METHOD: The modified MDS scale was subjected to content and cultural validity. The scale was administered to 347 nurses. Psychometric analysis were performed to assess construct validity. RESULTS: The scale consists of 11 items, investigating MD in nursing practice in different clinical settings. The dimensionality of the scale was investigated through exploratory factor analysis (EFA), which showed a two-dimensional structure labeled futility and potential damage. The futility refers to feelings of powerlessness and ineffectiveness in some clinical situations; the potential damage dimension captures feelings of powerlessness when nurses are forced to tolerate or perform perceived abusive clinical proceedings. Nurses who experienced higher MD, were more lilely to experience burnout. CONCLUSIONS: The modified MDS showed good psychometric properties, and it is valid and reliable for assessing moral distress among Italian nurses. Hence, the modified MDS allows to monitor the distress experienced by nurses and it is an important contribution to the scientific community and all those dealing with well-being of health workers.

For barn under skolealder finnes det fa tilgjengelige objektive diagnostiske undersokelser, og retningslinjene for diagnose og behandling er basert pa sykehistorie og klinisk undersokelse. Dette kan gi rom for varierende behandlingspraksis. MATERIALE OG METODE: Data fra Reseptregisteret ble brukt til a studere forskrivning av legemidler mot astma til barn i aldersgruppene 0-4 ar og 5-9 ar fordelt pa fylker fra 2004-15. RESULTATER: Det var stor variasjon mellom fylkene i andelen per 1 000 barn som fikk forskrevet legemidler mot astma i perioden 2012-14 (aldersgruppen 0-4 ar: median: 104/1 000; ekstremverdier: 64-147, aldersgruppen 5 9 ar: 68/1000; 46-86). Inhalasjonssteroider var hyppigst forskrevet, og det var her variasjonen mellom fylkene var storst i begge aldersgruppene (aldersgruppen 0 4 ar: 85/1 000; 42-116, aldersgruppen 5-9 ar: 51/1 000; 31-70).

PMID- 29460607 TI - Battered child syndrome in the records of the Department of Forensic Medicine, Medical University of Bialystok. AB - Violence against children has been until now recognised as physical aggression escalating from corporal punishment, hard physical labour to homicide. Nowadays child abuse is considered as maltreatment occurring in four different aspects: physical abuse, psychological abuse, sexual abuse and neglect. Child abuse is difficult to disclose, as it is concealed both by the perpetrators and the victims. The child is afraid and at the same time, almost always ashamed of looking for help. The victim frequently feels guilty, considers the violence as a norm, but in many cases is not able to speek precisely and very often has problems in contacting the required person. The objective of this study is to analyse the phenomenon of child abuse on the basis of Department of Forensic Medicine records. The victims were characterized in terms of their age, sex, place of residence and the type and location of injuries. The kind of abuse and perpetrators were also determined by researchers. PMID- 29460608 TI - Estimation of stature from sternal lengths. A correlation meta-analysis. AB - AIM OF THE STUDY:: Methods based on the positive linear relationship existing between stature and long bones are most commonly used to estimate living stature in forensic anthropology. The length of the sternum and its parts has been advanced as a plausible alternative to estimate stature when such long bones are missing or damaged. MATERIAL AND METHODS: This meta-analysis aims to quantify evidence on the correlation between the sternum/sternal parts length and stature. Nine studies were included with 1118 sternal bones. RESULTS: Analyses showed that the length of the meso-sternum (manubrium + body) yielded the best correlation with stature; 53.5% and 55.42% for men and women, respectively. The second best variable is the total sternal length with correlations of 44.3% and 55% for men and women, respectively. Subgroup analysis of autopsy studies demonstrated even a higher correlation of 58.2% for the meso-sternal length. Manubrium and body lengths showed the least correlation values. Except for the body length, females exhibit a better correlation than man between all other sternal lengths and stature. CONCLUSIONS: While the meso-sternal length is found to be the most correlated variable with stature, all sternal lengths are to be considered with caution when estimating stature. The relatively low values of the weighted correlation results should raise the question of reliability and limit the use of sternal length when long bones are available. Future research using larger samples from different populations and taking into account the fusion status of the sternum are needed.

MATERIAL AND METHODS: The prepared samples were identified employing an analytical procedure where the analytes were investigated by gas chromatography-electron impact mass spectrometry (GC-EI-MS) using a created library of mass spectra. RESULTS: The analysis revealed the following substances in the investigated products: piperazine derivatives (including BZP, MPMP, TFMPP), cathinone derivatives (including: pentedrone, 3 MMC, butylone, 4-MEC), pyrovalerone derivatives (MDPV, naphyrone, alpha-PVP, alpha-PVT), synthetic cannabinoids (such as AM-2201, UR-144, XLR-11, JWH073, JWH081, PB-22, AB-CHMINACA). Research conducted in 2010-2015 made it possible to track changes in the composition of investigated preparations. CONCLUSIONS: The following relationships has been shown: number of components decreased and in the end of 2015 dominated preparations with single component; introduction of amendments Act on Preventing Drug Addictionn affect the elimination from the market of one compounds and replacing them by their derivatives; since 2011 on the market of 'legal highs' we did not observe occurrence of compounds of piperazine group. PMID- 29460610 TI - Vitreous humour - routine or alternative material for analysis in forensic medicine. AB - Biological materials used in toxicological analyses in forensic medicine traditionally include blood, urine and vitreous humour. Forensic use of the vitreous body is mostly due to the need to assess the endogenous concentration of ethyl alcohol in the process of human body decomposition. The vitreous body is an underestimated biological material, even though its biochemical properties and anatomical location make it suitable for specific forensic toxicology tests as a reliable material for the preparation of forensic expert opinions. Based on the available literature the paper gathers information on the biochemical structure of the vitreous body, ways to secure the material after collection and its use in postmortem diagnostics. Specific applications of the vitreous humour for biochemical and toxicological tests are discussed, with a focus on its advantages and limitations in forensic medical assessment which are attributable to its biochemical properties, anatomical location and limited scientific studies on the distribution of xenobiotics in the vitreous body. PMID- 29460611 TI - Defendant's or convict's competency to stand trial - forensic psychiatric evaluation. AB - The purpose of this paper was to draw attention to particularly important aspects of pronouncing forensic psychiatric judgment regarding the accused or convicted individuals' competency to stand trial. The level of a person's mental capacity should be established using a structured psychiatric interview concerning a variety of aspects of a trial. Emphasis should be placed on evaluating the defendant's consciousness of the charges, knowledge of the potential punishment, ability to make significant decisions and be engaged in defense, knowledge about the role that particular people present in the courtroom play, understanding of the meaning of the evidence gathered in the case, the risk of aggression. The analysis should take into account the specificity of the mental disorder, the influence of proceedings on the course of disorder, as well as the presence of reactive disorders. Using testing tools by the expert can facilitate the process of evaluation to a certain degree. Forensic psychiatric evaluations can give rise to difficulties for the experts, what with the changing legal regulations and their interpretations. It would be justified to develop the standards of evaluation in this kind of cases, which would on the one hand apply to experts but which would also be respected by the judicial organ. PMID- 29460612 TI - SNPs and STRs in forensic medicine. A strategy for kinship evaluation. AB - Some emerging technologies are used as strategies for the analyses of single nucleotide polymorphisms (SNPs) that have attracted much interest in recent years, applied to various scientific areas. They have been extensively used as markers to identify genes that underlie complex diseases and also to realize the potential of pharmacogenomics in relation to different drug responses. Additionally, SNPs have been shown to be very useful in forensic genetics resolving all kinds of legal problems, namely crime cases, disaster victim identification and paternity and kinship investigation testing. The low mutation rate of SNPs, makes these markers very suitable for relationship testing. In the great majority of the cases, analyses with the widely used sets of STR markers provide powerful statistical evidence but some of them remain with ambiguous results. Those include cases with complex pedigrees or cases with some problems, like mutations, that are inherent to the use of STRs. At this time several forensic laboratories are using SNPs especially to complement the study of STRs in some of their casework cases. This paper intends to analyze some of our casework examples and to providea data update on the joint use of STRs and autosomal SNPs in the evaluation and kinship calculation, one of the strategies currently used for this purpose, namely reviewing and comparing results published by various working groups.

PMID- 29460614 TI - Influences of Conjugation Length on Organic Field-Effect Transistor Performances and Thin Film Structures of Diketopyrrolopyrrole-Oligomers. AB - Here, two diketopyrrolopyrrole (DPP)-based oligomers, DPP-4T and DPP-6T, are studied to reveal the influences of conjugation length on thin-film morphology and organic field-effect transistor (OFET) performances. PDMS-assisted crystallization in a solvent-annealing chamber is applied to prepare crystal arrays of DPP-4T and DPP-6T to optimize the quality of charge channels for OFET characterizations. To deliver insights into microstructure and morphology of thin films, a characterization procedure for determining molecular packing in thin film and crystallinity of the crystal arrays is presented via grazing incidence wide-angle X-ray scattering, electron diffraction, and lattice simulation software package (Cerius2). With the lattice parameters derived from analyses of grazing incidence wide-angle X-ray scattering (GIWAXS) and electron diffraction (ED), the lattice modeling results indicate that the inferior organic field effect transistor (OFET) performances of DPP-6T are attributed to longer pi stacking distance. Also, less-ordered molecular arrangement and lower continuity of crystalline domains, both of which are revealed from crystallinity results, lead to lower mobility of DPP-6T. In this case, longer conjugated backbones with more conformational degrees of freedom thus cause inherent crystal defects during the crystal growth process, despite the potential to enhance intermolecular pi orbital overlap. Therefore, to achieve better OFET performance, suitable backbone length makes conjugated oligomers give high intermolecular pi-orbital overlap and low density of structural disorder, which are the priorities for constructing good charge channel.

AB - Thermoelectric Bi2Te3 and Sb2Te3 thin films with high power factor were successfully obtained by pulsed laser deposition (PLD). Here, we demonstrate a well-controlled deposition of Bi2Te3/Sb2Te3 structures on glass substrates, through a shadow mask with micrometer-scale features. We establish an optimal growth temperature of 45 degrees C to attain compounds with suitable stoichiometric composition, as well as structural and electrical properties, to achieve high thermoelectric power factor. These films are produced without additional postannealing treatment or added gases. Indeed, crystalline films with Seebeck coefficients of 624 and -78 MUV K-1 are obtained for Sb2Te3 and Bi2Te3, respectively. Microgenerators consisting of four pairs of n-type Bi2Te3 and p type Sb2Te3 legs connected in series generate a maximum voltage of 50 mV and a power density of around 120 MUW cm-2 for a temperature difference of 30 K across the hot and cold ends of the device. This low-temperature and simple PLD deposited device represents an important step toward practical thermoelectric materials as well as efficient and compact microgenerators for low-temperature energy-harvesting applications. PMID- 29460617 TI - Pharmacological Inhibition of O-GlcNAcase Enhances Autophagy in Brain through an mTOR-Independent Pathway. AB - The glycosylation of nucleocytoplasmic proteins with O-linked N-acetylglucosamine residues (O-GlcNAc) is conserved among metazoans and is particularly abundant within brain. O-GlcNAc is involved in diverse cellular processes ranging from the regulation of gene expression to stress response. Moreover, O-GlcNAc is implicated in various diseases including cancers, diabetes, cardiac dysfunction, and neurodegenerative diseases. Pharmacological inhibition of O-GlcNAcase (OGA), the sole enzyme that removes O-GlcNAc, reproducibly slows neurodegeneration in various Alzheimer's disease (AD) mouse models manifesting either tau or amyloid pathology. These data have stimulated interest in the possibility of using OGA selective inhibitors as pharmaceuticals to alter the progression of AD. The mechanisms mediating the neuroprotective effects of OGA inhibitors, however, remain poorly understood. Here we show, using a range of methods in neuroblastoma N2a cells, in primary rat neurons, and in mouse brain, that selective OGA inhibitors stimulate autophagy through an mTOR-independent pathway without obvious toxicity. Additionally, OGA inhibition significantly decreased the levels of toxic protein species associated with AD pathogenesis in the JNPL3 tauopathy mouse model as well as the 3*Tg-AD mouse model. These results strongly suggest that OGA inhibitors act within brain through a mechanism involving enhancement of autophagy, which aids the brain in combatting the accumulation of toxic protein species. Our study supports OGA inhibition being a feasible therapeutic strategy for hindering the progression of AD and other neurodegenerative diseases. Moreover, these data suggest more targeted strategies to stimulate autophagy in an mTOR-independent manner may be found within the O-GlcNAc pathway. These findings should aid the advancement of OGA inhibitors within the clinic.

AB - The twin arginine translocation (Tat) system moves folded proteins across the cytoplasmic membrane of bacteria and the thylakoid membrane of plant chloroplasts. Signal peptide-bearing substrates of the Tat pathway (precursor proteins) are recognized at the membrane by the TatBC receptor complex. The only established preparation of the TatBC complex uses the detergent digitonin, rendering it unsuitable for biophysical analysis. Here we show that the detergent glyco-diosgenin (GDN) can be used in place of digitonin to isolate homogeneous TatBC complexes that bind precursor proteins with physiological specificity. We use this new preparation to quantitatively characterize TatBC-precursor interactions in a fully defined system. Additionally, we show that the GDN solubilized TatBC complex co-purifies with substantial quantities of phospholipids. PMID- 29460618 TI - Biosynthesis of Phenylglyoxylic Acid by LhDMDH, a Novel d-Mandelate Dehydrogenase with High Catalytic Activity. AB - d-Mandelate dehydrogenase (DMDH) has the potential to convert d-mandelic acid to phenylglyoxylic acid (PGA), which is a key building block in the field of chemical synthesis and is widely used to synthesize pharmaceutical intermediates or food additives. A novel NAD+-dependent d-mandelate dehydrogenase was cloned from Lactobacillus harbinensi (LhDMDH) by genome mining and expressed in Escherichia coli BL21. After being purified to homogeneity, the oxidation activity of LhDMDH toward d-mandelic acid was approximately 1200 U.mg-1, which was close to four times the activity of the probe. Meanwhile, the kcat/ Km value of LhDMDH was 28.80 S-1.mM-1, which was distinctly higher than the probe. By coculturing two E. coli strains expressing LhDMDH and LcLDH, we developed a system for the efficient synthesis of PGA, achieving a 60% theoretical yield and 99% purity without adding coenzyme or cosubstrate. Our data supports the implementation of a promising strategy for the chiral resolution of racemic mandelic acid and the biosynthesis of PGA.

AB - We report the preparation of alkali and alkaline earth (Ae) metal complexes supported by 2-picolylamino-diphenylphosphane chalcogenide [(Ph2P(=E)NHCH2(C5H4N)] [E = S (1-H); Se (2-H)] ligands. The treatment of the protic ligand, 1-H or 2-H, with alkali metal hexamethyldisilazides at room temperature afforded the corresponding alkali metal salts [M(THF)2(Ph2P(=E)NCH2(C5H4N)] [M = Li, E = S (3a), Se (3b)] and [{M(THF) n(Ph2P(=E)NCH2(C5H4N)}2] [M = Na, E = S (4a), Se (4b); M = K, E = Se (5b)] in good yield. The homoleptic Ae metal complexes [kappa2 (Ph2P(=Se)NCH2(C5H4N)Mg(THF)] (6b) and [kappa3-{(Ph2P(=Se)NCH2(C5H4N)}2M(THF) n] (M = Ca (7b), Sr (8b), Ba (9b)] were synthesized by the one-pot reaction of 2-H with [KN(SiMe3)2] and MI2 in a 2:2:1 molar ratio at room temperature. The molecular structures of the protic-ligands 1-H and 2-H, as well as complexes 3a,b 5a,b and 6b-9b were established using single-crystal X-ray analysis. The Ae metal complexes 6b-9b were tested for ring-opening polymerization (ROP) of racemic lactide ( rac-LA) and copolymerization of rac-LA and epsilon-caprolactone (epsilon-CL) at room temperature. In the ROP of rac-LA, the calcium complex 7b exhibited high isoselectivity, with Pi = 0.89, whereas both the barium and strontium complexes showed lower isoselectivity with Pi = 0.78-0.62. In the copolymerization of rac-LA and epsilon-CL, both barium and strontium complexes proved to be efficient precatalysts for the formation of the block copolymer rac LA-CL, but the reactivity of 9b was found to be better than that of 8b. All the polymers were fully characterized using differential scanning calorimetry, thermogravimetric analysis, and gel permeation chromatography analyses. Kinetic studies on the ROP reaction of LA confirmed that the rate of polymerization followed the order Ba ? Sr ~ Ca. PMID- 29460620 TI - Development of Smart Optical Gels with Highly Magnetically Responsive Bicelles. AB - Hydrogels delivering on-demand tailorable optical properties are formidable smart materials with promising perspectives in numerous fields, including the development of modern sensors and switches, the essential quality criterion being a defined and readily measured response to environmental changes. Lanthanide ion (Ln3+)-chelating bicelles are interesting building blocks for such materials because of their magnetic responsive nature. Imbedding these phospholipid-based nanodiscs in a magnetically aligned state in gelatin permits an orientation dependent retardation of polarized light. The resulting tailorable anisotropy gives the gel a well-defined optical signature observed as a birefringence signal. These phenomena were only reported for a single bicelle-gelatin pair and required high magnetic field strengths of 8 T. Herein, we demonstrate the versatility and enhance the viability of this technology with a new generation of aminocholesterol (Chol-NH2)-doped bicelles imbedded in two different types of gelatin. The highly magnetically responsive nature of the bicelles allowed to gel the anisotropy at commercially viable magnetic field strengths between 1 and 3 T. Thermoreversible gels with a unique optical signature were generated by exposing the system to various temperature conditions and external magnetic field strengths. The resulting optical properties were a signature of the gel's environmental history, effectively acting as a sensor. Solutions containing the bicelles simultaneously aligning parallel and perpendicular to the magnetic field directions were obtained by mixing samples chelating Tm3+ and Dy3+. These systems were successfully gelled, providing a material with two distinct temperature dependent optical characteristics. The high degree of tunability in the magnetic response of the bicelles enables encryption of the gel's optical properties. The proposed gels are viable candidates for temperature tracking of sensitive goods and provide numerous perspectives for future development of tomorrow's smart materials and technologies. PMID- 29460621 TI - Differential Protein Dynamics of Regulators of G-Protein Signaling: Role in Specificity of Small-Molecule Inhibitors. AB - Small-molecule inhibitor selectivity may be influenced by variation in dynamics among members of a protein family. Regulator of G-protein Signaling (RGS) proteins are a family that plays a key role in G-Protein Coupled Receptor (GPCR) signaling by binding to active Galpha subunits and accelerating GTP hydrolysis, thereby terminating activity. Thiadiazolidinones (TDZDs) inhibit the RGS-Galpha interaction by covalent modification of cysteine residues in RGS proteins. Some differences in specificity may be explained by differences in the complement of cysteines among RGS proteins. However, key cysteines shared by RGS proteins inhibited by TDZDs are not exposed on the protein surface, and differences in potency exist among RGS proteins containing only buried cysteines. We hypothesize that differential exposure of buried cysteine residues among RGS proteins partially drives TDZD selectivity. Hydrogen-deuterium exchange (HDX) studies and molecular dynamics (MD) simulations were used to probe the dynamics of RGS4, RGS8, and RGS19, three RGS proteins inhibited at a range of potencies by TDZDs. When these proteins were mutated to contain a single, shared cysteine, RGS19 was found to be most potently inhibited. HDX studies revealed differences in alpha4 and alpha6 helix flexibility among RGS isoforms, with particularly high flexibility in RGS19. This could cause differences in cysteine exposure and lead to differences in potency of TDZD inhibition. MD simulations of RGS proteins revealed motions that correspond to solvent exposure observed in HDX, providing further evidence for a role of protein dynamics in TDZD selectivity.

AB - At similar smoking levels, African American's lung cancer risk is as much as twice that of whites. We hypothesized that racial/ethnic differences in UDP glucuronosyltransferase (UGT)-catalyzed glucuronidation of 4-(methylnitrosamino) 1-(3-pyridyl)-1-butanol (NNAL), a detoxication pathway for the tobacco-specific lung carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) may contribute to this variable risk. UGT2B10 catalyzes NNAL- N-glucuronidation, and a UGT2B10 splice variant is common among African Americans. Smokers from two independent studies were genotyped for this variant (rs116294140) and an Asp67Tyr variant (rs61750900), and urinary NNAL and NNAL-glucuronide concentrations were quantified. In the first, no significant differences in NNAL- N-glucuronidation between African Americans ( n = 257) and whites ( n = 354) or between homozygous carriers of UGT2B10 variants (genetic score 2) and noncarriers (score 0) were detected. However, total NNAL glucuronidation by score 2 compared to score 0 smokers was lower (68.9 vs 71.2%, p < 0.0001). For NNAL- N-glucuronide to be more precisely quantified in a second study, a sensitive high-resolution LC-MS/MS based method, which separated NNAL, NNAL- O-glucuronide, and NNAL- N-glucuronide prior to analysis, was developed. In this study, the excretion of total NNAL (free plus glucuronides) by African American ( n = 52) and white ( n = 54) smokers was not different; however, total NNAL glucuronidation by African Americans (64.0%) was slightly less than by whites (68.3%, p = 0.05). The mean NNAL- N-glucuronidation by African Americans was much lower than for whites (14 vs 24.9%, p < 0.00001), but the NNAL- O-glucuronidation was greater (50.0 vs 43.3%, p = 0.013). UGT2B10 genotype influenced NNAL- N-glucuronidation; the geometric mean percentage N-glucuronidation was 22.5% for smokers with genetic score 0 ( n = 57) and 11.2% for score 2 ( n = 11). In summary, the high prevalence of a UGT2B10 splice variant among African Americans results in lower NNAL- N-glucuronidation but only a small decrease in total NNAL glucuronidation. Therefore, despite the significant contribution of UGT2B10 to NNAL- N glucuronidation, the UGT2B10 genotype does not play a large role in NNAL detoxication. Any decrease in N-glucuronidation was accompanied by a parallel increase in O-glucuronidation.

AB - The reactive nature of carbenes can be modulated, and ultimately reversed, by receiving additional electron density from a metal. Here, it is shown that Au nanoparticles (NPs) generate an electron-rich carbene on surface after transferring electron density to the carbonyl group of an in situ activated diazoacetate, as assessed by Fourier transformed infrared (FT-IR) spectroscopy, magic angle spinning nuclear magnetic resonance (MAS NMR), and Raman spectroscopy. Density functional theory (DFT) calculations support the observed experimental values and unveil the participation of at least three different Au atoms during carbene stabilization. The surface stabilized carbene shows an extraordinary stability against nucleophiles and reacts with electrophiles to give new products. These findings showcase the ability of catalytic Au NPs to inject electron density in energetically high but symmetrically allowed valence orbitals of sluggish molecules. PMID- 29460624 TI - Multifunctional Nickel Phosphate Nano/Microflakes 3D Electrode for Electrochemical Energy Storage, Nonenzymatic Glucose, and Sweat pH Sensors. AB - Multifunctional, low-cost electrodes and catalysts are desirable for next generation electrochemical energy-storage and sensor applications. In this study, we demonstrate the fabrication of Ni3(PO4)2.8H2O nano/microflakes layer on nickel foam (NF) by a facile one-pot hydrothermal approach and investigate this electrode for multiple applications, including sweat-based glucose and pH sensor as well as hybrid energy-storage device, e.g., supercapattery. The electrode displays a specific capacity of 301.8 mAh g-1 (1552 F g-1) at an applied current of 5 mA cm-2 and can retain 84% of its initial capacity after 10 000 cycles. Furthermore, the supercapattery composed of Ni3(PO4)2.8H2O/NF as positive electrode and activated carbon as negative electrode can offer a high specific energy of 33.4 Wh kg-1 with the power of 165.5 W kg-1. As an electrocatalyst for nonenzymatic glucose sensor, Ni3(PO4)2.8H2O/NF shows an exceptional sensitivity (24.39 mA mM-1cm-2) with a low detection limit of 97 nM (S/N = 3). Moreover, as a sweat-based pH sensor, the electrode is capable of detecting human sweat pH values ranging from 4 to 7. Therefore, this three-dimensional nanoporous Ni3(PO4)2.8H2O/NF electrode, due to its excellent electrochemical performance, can be successfully applied in electrochemical energy-storage and biosensor applications.

AB - Siderophores are a structurally diverse class of natural products common to most bacteria and fungi as iron(III)-chelating ligands. Siderophores, including trihydroxamate ferrioxamines, are used clinically to treat iron overload diseases and show promising activity against many other iron-related human diseases. Here, we present a new method for the isolation of ferrioxamine siderophores from complex mixtures using affinity chromatography based on resin-immobilized FhuD2, a siderophore-binding protein (SBP) from Staphylococcus aureus. The SBP-resin enabled purification of charge positive, charge negative, and neutral ferrioxamine siderophores. Treatment of culture supernatants from Streptomyces violaceus DSM 8286 with SBP-resin provided an analytically pure sample of the salmycins, a mixture of structurally complex glycosylated sideromycins (siderophore-antibiotic conjugates) with potent antibacterial activity toward human pathogenic Staphylococcus aureus (minimum inhibitory concentration (MIC) = 7 nM). Siderophore affinity chromatography could enable the rapid discovery of new siderophore and sideromycin natural products from complex mixtures to aid drug discovery and metabolite identification efforts in a broad range of therapeutic areas. PMID- 29460626 TI - Correlation of Device Performance and Fermi Level Shift in the Emitting Layer of Organic Light-Emitting Diodes with Amine-Based Electron Injection Layers. AB - We investigate three amine-based polymers, polyethylenimine and two amino functionalized polyfluorenes, as electron injection layers (EILs) in organic light-emitting diodes (OLEDs) and find correlations between the molecular structure of the polymers, the electronic alignment at the emitter/EIL interface, and the resulting device performance. X-ray photoelectron spectroscopy measurements of the emitter/EIL interface indicate that all three EIL polymers induce an upward shift of the Fermi level in the emitting layer close to the interface similar to n-type doping. The absolute value of this Fermi level shift, which can be explained by an electron transfer from the EIL polymers into the emitting layer, correlates with the number of nitrogen-containing groups in the side chains of the polymers. Whereas polyethylenimine (PEI) and one of the investigated polyfluorenes (PFCON-C) have six such groups per monomer unit, the second investigated polyfluorene (PFN) only possesses two. Consequently, we measure Fermi level shifts of 0.5-0.7 eV for PEI and PFCON-C and only 0.2 eV for PFN. As a result of these Fermi level shifts, the energetic barrier for electron injection is significantly lowered and OLEDs which comprise PEI or PFCON-C as an EIL exhibit a more than twofold higher luminous efficacy than OLEDs with PFN. PMID- 29460627 TI - Pd Metal Catalysts for Cross-Couplings and Related Reactions in the 21st Century: A Critical Review. AB - Cross-couplings and related reactions are a class of highly efficient synthetic protocols that are generally promoted by molecular Pd species as catalysts. However, catalysts based on more or less highly dispersed Pd metal have been also employed for this purpose, and their use, which was largely limited to the Heck reaction until the turn of the century, has been extended in recent years to most reactions of this class. This review provides a critical overview on these recent applications of Pd metal catalysts. Particular attention is devoted to the discussion of the mechanistic pathways that have been proposed to explain the catalytic role of Pd metal. Furthermore, the most outstanding Pd metal based catalytic systems that have emerged are illustrated, together with the development of novel approaches to boost the reactivity of Pd metal. A section summarizing the current industrial applications of Pd metal catalyzed reactions of this kind concludes the review. PMID- 29460628 TI - Eight Inch Wafer-Scale Flexible Polarization-Dependent Color Filters with Ag-TiO2 Composite Nanowires. AB - In this study, 8 in. wafer-scale flexible polarization-dependent color filters with Ag-TiO2 composite nanowires have been fabricated using nanoimprint and E beam evaporation. The filters change their color via a simple rotation of the polarizer. In addition, the color of the filter can be controlled by altering the thickness of the Ag and TiO2 nanowires deposited on the polymer patterns. Polarization-dependent color filters were realized by selective inhibition of transmission using the plasmonic resonance at the insulator/metal/insulator nanostructure interface, which occurs at particular wavelengths for the transverse magnetic polarizations. Special colors, including purple, blue, green, yellow, and pink, could be obtained with high transmission beyond 65% by varying the thickness of the deposited Ag and TiO2 nanowires on the periodic polymer pattern under transverse magnetic polarization. In addition, a continuous color change was achieved by varying the polarization angle. Last, numerical simulations were implemented in comparison with the experimental results, and the mechanism was explained. We believe that this simple and cost-effective method can be applied to processes such as anticounterfeiting and holographic imaging as well as to color displays. PMID- 29460629 TI - Structural Evolution of a Retinal Chromophore in the Photocycle of Halorhodopsin from Natronobacterium pharaonis. AB - We revealed the chloride ion pumping mechanism in halorhodopsin from Natronobacterium pharaonis ( pHR) by exploring sequential structural changes in the retinal chromophore during its photocycle using time-resolved resonance Raman (RR) spectroscopy on the nanosecond to millisecond time scales. A series of RR spectra of the retinal chromophore in the unphotolyzed state and of the three intermediates of pHR were obtained. Using singular value decomposition analysis of the C?C and C-C stretch bands in the time-resolved RR spectra, we identified the spectra of the K, L, and N intermediates. We focused on structural markers of the RR bands to explore the structure of the retinal chromophore. In the unphotolyzed state, the retinal chromophore is in the planar all- trans, 15- anti geometry. The bound ion affects the polyene chain but does not interact with the protonated Schiff base. In the observed intermediates, the chromophore is in the 13- cis configuration. The chromophore in the K intermediate is distorted due to the photoisomerization of retinal. The hydrogen bond is weak in the unphotolyzed state and in the K intermediate, resulting in exchange of the hydrogen-bond acceptor to a water molecule in the K-to-L transition, relaxation of the polyene chain distortion, and generation of an alternative distortion near the Schiff base. The bound halide ion interacts with the protonated Schiff base through the water molecule bound to the protonated Schiff base. In the L-to-N transition, the hydrogen acceptor of the protonated Schiff base switches from the water molecule to another species, although the strong hydrogen bond of the protonated Schiff base remains. This paper reports the first observation of sequential changes in the RR spectra in the pHR photocycle, provides information on the structural evolution of the retinal chromophore, and proposes a model for chloride ion translocation in pHR. PMID- 29460630 TI - Insights on the Origin of Catalysis on Glycine N-Methyltransferase from Computational Modeling. AB - The origin of enzyme catalysis remains a question of debate despite much intense study. We report a QM/MM theoretical study of the SN2 methyl transfer reaction catalyzed by a glycine N-methyltransferase (GNMT) and three mutants to test whether recent experimental observations of rate-constant reductions and variations in inverse secondary alpha-3H kinetic isotope effects (KIEs) should be attributed to changes in the methyl donor-acceptor distance (DAD): Is catalysis due to a compression effect? Semiempirical (AM1) and DFT (M06-2X) methods were used to describe the QM subset of atoms, while OPLS-AA and TIP3P classical force fields were used for the protein and water molecules, respectively. The computed activation free energies and KIEs are in good agreement with experimental data, but the mutations do not meaningfully affect the DAD: Compression cannot explain the experimental variations on KIEs. On the contrary, electrostatic properties in the active site correlate with the catalytic activity of wild type and mutants. The plasticity of the enzyme moderates the effects of the mutations, explaining the rather small degree of variation in KIEs and reactivities.

AB - Molybdenum disulfide (MoS2) is a well-known and effective lubricant that provides extremely low values of coefficient of friction. It is known that the sliding process may induce structural transformations of amorphous or disordered MoS2 to the crystalline phase with basal planes oriented parallel to the sliding direction, which is optimal for reducing friction. However, the key reaction parameters and conditions promoting this structural transformation are still largely unknown. We investigate, by employing reactive molecular dynamics simulations, the formation of MoS2 layers from an amorphous phase as a function of temperature, initial sample density, and sliding velocity. We show that the formation of ordered crystalline structures can be explained in the framework of classical nucleation theory as it predicts the conditions for their nucleation and growth. These results may have important implications in the fields of coating and thin-film deposition, tribology, and in all technological applications where a fast and effective structural transition to an ordered phase is needed.

AB - A novel enantioselective approach to the synthesis of a compound collection inspired by natural pyrrolizidine alkaloids was developed, employing an enantioselectively catalyzed 1,3-dipolar cycloaddition as the key step. The cycloadducts were obtained with excellent enantio- and diastereoselectivity. Biological evaluation of the resulting compound collection revealed that the compound class has multiple bioactivities, including activity against Plasmodium falciparum 3D7 and inhibition of Hedgehog signaling. PMID- 29460634 TI - Serum Metabolomics Study of Gliclazide-Modified-Release-Treated Type 2 Diabetes Mellitus Patients Using a Gas Chromatography-Mass Spectrometry Method. AB - Sulfonylureas are one of the commonly used drugs in type 2 diabetes mellitus (T2DM) but with considerable incidence of monotherapy failure. However, the mechanism of patients' drug response is unclear, and suitability evaluation biomarkers are in urgent need for precision medicine. In this study, a pseudotargeted gas chromatography-mass spectrometry method was employed to investigate the serum metabolic profiling of 66 significant responders and 24 nonsignificant responders at baseline and 16 weeks after gliclazide modified release (MR) monotherapy. Clinical improvements in blood glucose level and insulin sensitivity were closely associated with the alterations of TCA cycle, ketone body metabolism, lipid oxidation, branched-chain amino acid catabolism, and gut flora metabolism. The different baseline metabolic profiling observed in the two groups implied that patients with lower dyslipidemia level may be more suitable for sulfonylurea therapy. The biomarker panel consisting of HbA1c, 5,8,11,14,17-eicosapentaenoic acid, methyl 8,11,14-eicosatrienoate, and methyl hexadecanoate shows a very good prediction ability for the suitability of gliclazide treatment, and it may be meaningful in personalized medicine of T2DM patients by sulfonylurea therapy. PMID- 29460635 TI - Nivolumab in the treatment of advanced renal cell carcinoma. AB - Renal cell carcinoma (RCC) has typically been considered an immunogenic malignancy with responses seen to IL-2 and IFN-alpha. Response rates, however, were low and at the cost of considerable toxicity and as such, agents targeting angiogenesis have become the mainstay of treatment. Nivolumab is an immune checkpoint inhibitor targeting PD-1 thereby upregulating the host immune response against tumor cells. Nivolumab has emerged as a promising new therapy in advanced malignancies, and the first agent to show survival advantage in patients failing prior VEGFR-targeted therapy in metastatic RCC. This review summarizes the present evidence, toxicity profile, potential predictive biomarkers and promising future strategies with nivolumab in metastatic RCC. PMID- 29460636 TI - Neurological, physical and sociodemographic correlates of employment in multiple sclerosis: A meta-analysis. AB - Illness severity and sociodemographic characteristics of 7,053 employees with multiple sclerosis and 11,043 peers not in the workforce were compared (Hedges' g with 95% confidence interval and p values). Pooled findings from 25 studies confirmed the main role of a relapsing-remitting disease course and higher education to employment. To a lesser extent, disease duration, fatigue and pain symptoms and age also differentiated the two groups. Vocational interventions for persons with multiple sclerosis should focus on job retention, including mechanisms to accommodate and facilitate functional independence. Longitudinal data are needed to distinguish the characteristics of those who achieve and maintain competitive employment. PMID- 29460637 TI - Hospital usage of TOXBASE in Great Britain: Temporal trends in accesses 2008 to 2015. AB - AIM: To examine temporal trends in accesses to the UK's National Poison Information Service's TOXBASE database in Britain. METHODS: Generalized additive models were used to examine trends in daily numbers of accesses to TOXBASE from British emergency departments between January 2008 and December 2015. Day-of-the week, seasonality and long-term trends were analysed at national and regional levels (Wales, Scotland and the nine English Government Office Regions). RESULTS: The long-term trend in daily accesses increases from 2.8 (95% confidence interval (CI): 2.6-3.0) per user on 1 January 2008 to 4.6 (95% CI: 4.3-4.9) on 31 December 2015, with small but significant differences in population-corrected accesses by region ( p < 0.001). There are statistically significant seasonal and day of the week patterns ( p < 0.001) across all regions. Accesses are 18% (95% CI: 14-22%) higher in summer than in January and at the weekend compared to weekdays in all regions; there is a 7.5% (95% CI: 6.1-8.9%) increase between Friday and Sunday. CONCLUSIONS: There are consistent in-year patterns in access to TOXBASE indicating potential seasonal patterns in poisonings in Britain, with location dependent rates of usage. This novel descriptive work lays the basis for future work on the interaction of TOXBASE use with emergency admission of patients into hospital. PMID- 29460638 TI - Effectiveness of a Pediatric Abusive Head Trauma Prevention Program Among Spanish Speaking Mothers. AB - INTRODUCTION: This study aimed to evaluate participants' knowledge of and intent to share key messages of the Period of PURPLE Crying abusive head trauma prevention program among a majority Spanish-speaking population. METHODS: This study was a retrospective review of a postintervention survey administered in the perinatal unit of a community birthing hospital. Surveys were administered to mothers of newborns by perinatal nurses as part of routine process evaluation prior to hospital discharge between May 30, 2014, and May 15, 2015. RESULTS: A majority of participants (86.4%) answered all six knowledge questions correctly. Among participants who reported that the father or significant other was not present during the PURPLE education (44.1%), all (100%) reported intending to share the PURPLE information with their partners. The majority of participants (88.1%) intended to share the information with others who take care of their infants. CONCLUSION: The PURPLE abusive head trauma prevention program demonstrated positive preliminary results in knowledge and intended behavior among a population of majority Spanish-speaking participants. These findings offer an important first step toward provision of effective universal abusive head trauma prevention among growing Spanish-speaking populations. Further evaluation is needed of acceptability, retention of messages, and postintervention behavior change among Spanish-speaking participants and nurses. PMID- 29460639 TI - Planning Telehealth for Older Adults With Atrial Fibrillation in Rural Communities: Understanding Stakeholder Perspectives. AB - Older adults with atrial fibrillation (AF) in rural communities have less access to cardiac specialty care. Telehealth offers a viable approach to provide cardiac care, yet little is known about patients' and providers' views on telehealth's potential to support rural patients with AF. This qualitative descriptive study examines patient and health providers' perspectives, an important first step in planning a telehealth initiative. Eight patients with AF, along with one partner from rural communities, were recruited through an urban-based AF clinic. Five providers were recruited through professional practice leads in the health region. Semistructured telephone interviews were conducted with both stakeholder groups. The overriding theme was variability in patient and provider receptiveness to telehealth. Receptiveness reflected differences in past experience with telehealth, in perceived adequacy of rural health services, and in perceived gaps in AF care. These are important considerations in planning effective and sustainable telehealth in rural communities. PMID- 29460640 TI - Implications of HLA-allele associations for the study of type IV drug hypersensitivity reactions. AB - INTRODUCTION: Type IV drug hypersensitivity remains an important clinical problem and an obstacle to the development of new drugs. Several forms of drug hypersensitivity are associated with expression of specific HLA alleles. Furthermore, drug-specific T-lymphocytes have been isolated from patients with reactions. Despite this, controversy remains as to how drugs interact with immune receptors to stimulate a T-cell response. Areas covered: This article reviews the pathways of T-cell activation by drugs and how the ever increasing number of associations between expression of HLA alleles and susceptibility to hypersensitivity is impacting on our research effort to understanding this form of iatrogenic disease. Expert opinion: For a drug to activate a T-cell, a complex is formed between HLA molecules, an HLA binding peptide, the drug and the T-cell receptor. T-cell responses can involve drugs and stable or reactive metabolites bound covalently or non-covalently to any component of this complex. Recent research has linked the HLA associations to the disease through the characterization of drug-specific T-cell responses restricted to specific alleles. However, there is now a need to identify the additional genetic or environment factors that determine susceptibility and use our increased knowledge to develop predictive immunogenicity tests that offer benefit to Pharma developing new drugs. PMID- 29460641 TI - Novel blood glucose lowering therapies for managing type 1 diabetes in paediatric patients. AB - INTRODUCTION: Therapy for type 1 diabetes (T1D) is mainly restricted to insulin treatment. The management of paediatric patients with T1D should tackle not only glucose control, but also insulin resistance, beta-cell preservation, quality of life and cardiovascular disease risk factors, which are increasingly recognized to occur in adolescents with T1D. Areas covered: This review examines the recently published literature from PubMed on non-insulin agents for the management of T1D in paediatric patients. Expert opinion: Few paediatric patients with T1D are achieving their metabolic targets. Current data support the need for new strategies and the consideration of additional therapies that not only may help patients, their families and their physicians to meet HbA1c targets, but also may preserve residual islet mass and good quality of life and prevent microvascular and macrovascular complications, thereby, reducing hypoglycaemic episodes. Non-insulin adjunctive therapies may improve not only glucose control, but also insulin sensitivity, in addition to preserving beta-cell function in T1D patients. Thus, more studies are required to define the potential role of these therapies in the management of paediatric patients. PMID- 29460642 TI - Novel targeted therapy strategies for biliary tract cancers and hepatocellular carcinoma. AB - Worldwide hepatobiliary cancers are the second leading cause of cancer related death. Despite their relevance, hepatobiliary cancers have a paucity of approved systemic therapy options. However, there are a number of emerging therapeutic biomarkers and therapeutic concepts that show promise. In hepatocellular carcinoma, nivolumab appears particularly promising and recently received US FDA approval. In intrahepatic cholangiocarcinoma, therapies targeting FGFR2 and IDH1 and immune checkpoint inhibitors are the furthest along and generating the most excitement. There are additional biomarkers that merit further exploration in hepatobiliary cancers including FGF19, ERRFI1, TERT, BAP1, BRAF, CDKN2A, tumor mutational burden and ERBB2 (HER2/neu). Development of new and innovative therapies would help address the unmet need for effective systemic therapies in advanced and metastatic hepatobiliary cancers. PMID- 29460643 TI - Para-ovarian adrenal rest tumors: gynecologic manifestations of untreated congenital adrenal hyperplasia. AB - Congenital adrenal hyperplasia (CAH) is an inherited disorder of adrenal steroidogenesis often diagnosed in infancy. Gynecologists may encounter adult patients with CAH due to the clinical effects of increased androgens, e.g. hirsutism, clitoromegaly, oligomenorrhea, or, rarely, pelvic masses. This case report reviews the association of para-ovarian adrenal rest tumors with CAH, and the role of gynecologists in their evaluation and treatment. A 23-year-old woman with CAH (21-hydroxyase deficiency) untreated for the past 5 years presented with a pelvic mass and elevated serum testosterone (1433 ng/dL) and plasma ACTH (1117 pg/mL). Intraoperative findings revealed multiple retroperitoneal masses. Final pathology demonstrated adrenal rest tissue. Para-ovarian and ovarian adrenal rest tumors may present as a rare gynecologic manifestation in patients with untreated CAH. PMID- 29460644 TI - Functional Outcomes of Symptomatic Implant Removal Following Ankle Fracture Open Reduction and Internal Fixation. AB - BACKGROUND: Orthopedic implant removal following open reduction internal fixation of a fracture is a common procedure, especially in the foot and ankle. The purpose of this study was to evaluate functional change after the removal of symptomatic implants following ankle fracture open reduction internal fixation (ORIF) using the Short Musculoskeletal Function Assessment (SMFA) outcome score. We hypothesized that implant removal after ankle fracture would result in improved functional outcomes. METHODS: Retrospective review of prospectively collected data on patients with a closed ankle fracture between 2013 and 2016 was performed. Inclusion criteria were skeletal maturity, symptomatic ankle implants and completion of the SMFA questionnaire prior to and 6 months after removal. Exclusion criteria were development of a nonunion, prior or current infection, peripheral neuropathy or ongoing litigation surrounding the surgery. The primary outcome was change in SMFA score from baseline to follow-up using Wilcoxon signed rank test. Additional logistic regression models evaluated the effects of age, sex, body mass index, smoking status, and patient American Society of Anesthesiologists scores. RESULTS: The study population consisted of 43 patients. There was a statistically significant improvement in function, represented by a decrease in SMFA scores from baseline to the 6-month follow-up period (? = -4.1 [95% confidence interval, -7.0, -1.3]; P = .003). Secondary outcome measures of the bother index and daily activities domain also demonstrated significant improvements ( P = .005 and P = .002, respectively). Additional logistical regression models identified no significant effects by assessed covariates for change in SMFA scores. CONCLUSION: Patients with symptomatic implants following ankle fracture ORIF had a statistically significant improvement in function following implant removal. There appears to be value in removing implants from the ankle in patients who report discomfort during daily activities. Further investigation into the specific indications for implant removal and the impact of injury and fracture pattern on outcomes is warranted. LEVEL OF EVIDENCE: Level IV, case series. PMID- 29460645 TI - Biomechanical Evaluation of Suture Configurations in Lesser Toe Plantar Plate Repairs. AB - BACKGROUND: Lesser toe metatarsal-phalangeal (MTP) joint instability can be a major source of pain and dysfunction. Instability occurs when there is incompetence of the plantar plate and/or collateral ligaments. Newer operative treatments focus on performing anatomic repairs of the plantar plate. The goal of this study was to compare the biomechanical properties of 3 suture configurations that may be used for plantar plate repairs. METHODS: Biomechanical analysis of 27 lesser toe plantar plates from fresh frozen human cadavers was completed. The plantar plate was detached from the proximal phalanx, and suture was placed in the distal plantar plate in a horizontal mattress, luggage-tag, or Mason-Allen suture configuration. Cyclic loading followed by load-to-failure testing was performed. RESULTS: There was a significant difference in peak load-to-failure force between constructs (mattress: 115.53 +/- 15.95 N; luggage-tag 102.42 +/- 19.33 N; Mason-Allen: 89.96 +/- 15.78 N; P = .015). Post hoc analysis demonstrated that the mattress configuration had significantly higher load-to failure force compared with the Mason-Allen configuration ( P = .004). There were no significant differences between the mattress and the luggage-tag configurations or the luggage-tag and the Mason-Allen configurations. There were no differences in construct stiffness, axial displacement at the time of failure, or number of cycles required to produce 2 mm of displacement. CONCLUSION: The mattress configuration demonstrated better peak load-to-failure force compared with the Mason-Allen configuration but was not statistically different from the luggage-tag configuration. Although not significant, the mattress configuration trended toward higher load-to-failure force compared with the luggage-tag. CLINICAL RELEVANCE: The horizontal mattress stitch may be the biomechanically superior configuration in plantar plate repairs. PMID- 29460646 TI - Sex hormone-binding globulin levels during the first trimester may predict gestational diabetes mellitus development. AB - AIM: To investigate the association of sex hormone-binding globulin (SHBG) levels of early pregnancy with gestational diabetes mellitus (GDM) development. METHODS: A total of 443 pregnant women during the first trimester (<12 weeks) were enrolled. SHBG levels were measured. RESULTS: SHBG level was lower in women with GDM than in women without GDM (93.9 +/- 34.4 nmol/l vs 128.1 +/- 60.3 nmol/l; p = 0.001). Among the four quartiles (Q1-Q4) according to SHBG levels, GDM incidences were 17.5, 27.8, 5.1 and 2.6%, respectively. No differences were found between Q1 and Q2, and Q3 and Q4. The risk of developing GDM among women in Q1 + Q2 compared with Q3 + Q4 was 5.7. CONCLUSION: Decreased SHBG concentrations during the first trimester may predict GDM development. PMID- 29460647 TI - Biomarkers for Sjogren's syndrome. AB - Sjogren's syndrome (pSS) is a complex and heterogeneous disorder characterized by different clinical subsets. Recently, great efforts have been made searching for reliable biomarkers able to ameliorate the diagnostic algorithm and the prognostic stratification of pSS patients and ultimately allowing the scientific community to address some of the unmet needs for the disease. In this review, we have summarized the state of the art of 'traditional' widely acknowledged clinical, serological and histologic biomarkers for pSS with the aim of highlighting their relevance and limitations in clinical practice. We have also explored some of the novel potential biomarkers that have been proposed more recently, potentially able to open new ways in the assessment of the disease. PMID- 29460648 TI - Telemonitoring and home hospitalization in patients with chronic obstructive pulmonary disease: study TELEPOC. AB - BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a major consumer of healthcare resources, with most costs related to disease exacerbations. Telemonitoring of patients with COPD may help to reduce the number of exacerbations and/or the related costs. On the other hand, home hospitalization is a cost-saving alternative to inpatient hospitalization associated with increased comfort for patients. The results are reported regarding using telemonitoring and home hospitalization for the management of patients with COPD. METHODS: Twenty-eight patients monitored their health parameters at home for six months. A nurse remotely revised the collected parameters and followed the patients as programmed. A home care unit was dispatched to the patients' home if an alarm signal was detected. The outcomes were compared to historical data from the same patients. RESULTS: The number of COPD exacerbations during the study period did not reduce but the number of hospital admissions decreased by 60% and the number of emergency room visits by 38%. On average, costs related to utilization of healthcare resources were reduced by ?1,860.80 per patient per year. CONCLUSIONS: Telemonitoring of patients with COPD combined with home hospitalization may allow for a reduction in healthcare costs, although its usefulness in preventing exacerbations is still unclear.

AB - CONTEXT: Human health is complex and multifaceted; there is a need for biomarkers that reflect the multidimensional nature of health. OBJECTIVE: To identify potential epigenomic biomarkers of health in women aged 18-40 participating in a six-month lifestyle intervention, next level health. MATERIALS AND METHODS: Methylation data were obtained by reduced representation bisulphite sequencing of 21 female intervention participants as well as three non-participants. The Differential Methylation Analysis Package (DMAP) was used to investigate inter- and intra-individual variability and to identify potential targets of transient epigenetic control in the population studied. RESULTS: Eleven genes were identified as significantly differentially methylated post- intervention in all 21 participants. 1884 genomic locations were found to be differentially methylated amongst the total female population studied representing potential epigenomic biomarkers. CONCLUSIONS: The ability to demonstrate epigenetic changes arising from a lifestyle intervention can provide key information on the relationship between gene regulation, human behaviour and health. PMID- 29460650 TI - A comparison of human natural monoclonal antibodies and aptamer conjugates for promotion of CNS remyelination: where are we now and what comes next? AB - INTRODUCTION: Multiple sclerosis (MS) is a chronic and progressive inflammatory demyelinating disease of the human central nervous system (CNS) and is the most common disabling neurological condition in young adults, resulting in severe neurological defects. No curative or long-term progression-inhibiting therapy has yet been developed. However, recent investigation has revealed potential strategies that do not merely modulate potentially pathogenic autoimmune responses, but stimulate remyelination within CNS lesions. Areas covered: We discuss the history and development of natural human IgM-isotype immunoglobulins (HIgMs) and recently-identified aptamer-conjugates that have been shown to enhance endogenous myelin repair in animal models of demyelination by acting on myelin-producing oligodendrocytes (OLs) or oligodendrocyte progenitor cells (OPCs) within CNS lesions. We also discuss future development aims and applications for these important novel technologies. Expert opinion: Aptamer conjugate Myaptavin-3064 and recombinant human IgM-isotype antibody rHIgM22 regenerate CNS myelin, thereby reducing axonal degeneration and offering the potential of recovery from MS relapses, reversal of disability and prevention of disease progression. Advancement of these technologies into the clinic for MS treatment is therefore a top priority. It remains unclear to what extent the therapeutic modalities of remyelinating antibodies and aptamers may synergize with other currently-approved therapies to yield enhanced therapeutic effects. PMID- 29460653 TI - Risk of osteoporosis in microscopic colitis. AB - OBJECTIVES: Patients with microscopic colitis (MC) have several risk factors for osteoporosis. The prevalence of osteopenia and osteoporosis in MC is unknown. The primary purpose of this study was to evaluate bone mineral status in MC. METHODS: Patients with MC and disease activity within the last 2 years were included. Bone turnover markers were analyzed and bone mineral density (BMD) was measured with Dual Energy X-ray Absorptiometry (DXA) at inclusion and after one year. Medical history, demographics, risk factors for osteoporosis, disease activity and treatment with cumulative budesonide dosage at least 3 years before inclusion was registered. Adrenal function was tested by adrenocortico-tropic hormone (ACTH) and an ACTH stimulation test at inclusion. Results were compared with age and sex matched controls. RESULTS: Fifty MC patients (44 women) were included. Median age 67 (range 45-93); median disease duration 28 month (range 2-163); median cumulative budesonide dosage 702 mg (range 0-5400). No difference in number of patients with osteoporosis or osteopenia and BMD was detected between groups. The bone mineral formation marker specific alkaline phosphatase was lower in MC than controls 12 (5-69) ug/l versus 16 (10-35) ug/l (p < 0.005). Patients more often smoked (34% versus 10%, p = 0.001). Disease duration and cumulative budesonide dose was associated with lower BMD and T-score in hip (Spearman's rho; p < 0.05) with a cut of point of 2500 mg budesonide predicting osteopenia. Budesonide treatment did not affect adrenal gland function. CONCLUSION: The risk of osteoporosis in patients with MC is not increased. However, DXA scan is recommended in MC patients with known risk factors or active disease requiring longstanding budesonide treatment. Supplementation of calcium and vitamin-D in patients treated with budesonide is recommended. PMID- 29460654 TI - Cumulative experience and long term follow-up of pentostatin-based chemoimmunotherapy trials for patients with chronic lymphocytic leukemia. AB - BACKGROUND: 7 regimens of pentostatin based chemoimmunotherapy (CIT) for progressive previously untreated CLL primarily with long term follow-up to update both efficacy and toxicity. RESEARCH DESIGN AND METHODS: Prognostic markers including assessment of IGVH and FISH status were done on all. Response rates and 95% binomial confidence intervals were calculated for each regimen and in the combined cohort. Overall survival and treatment-free survival were evaluated using Kaplan-Meier methods. RESULTS: The initial CIT trial was pentostatin (2 mgs/m2), cyclophosphamide (600 mg/m2) and rituximab (PCR) but subsequent P based CIT trials with modifications in subsequent trials. The cohort (n = 288) included 52% with unmutated IGVH status and del17p (4.5%) and del11q (14.9%). Toxicity profiles were primarily hematologic and no patient has developed MDS or AML after a median follow-up of 6.4 years. The overall response rate across all trials was found to be over 90% with a 41% complete response rate. We validated that the CLL IPI model segregates progressive CLL patients into 4 risk groups associated with OS and TFS. CONCLUSIONS: The high overall and complete response levels in favorable genetic risk CLL along with favorable toxicity profiles provide rationale for consideration of a PC based strategy for previously untreated progressive CLL. PMID- 29460655 TI - Clinical evidence for washing and cleansers in acne vulgaris: a systematic review. AB - PURPOSE: Washing and over-the-counter cleansers are common interventions in acne vulgaris (AV), but the clinical evidence for their benefit is poorly understood. This systematic review presents clinical studies of washing and cleanser efficacy in acne vulgaris to guide treatment recommendations of dermatologists. MATERIALS AND METHODS: We surveyed English-language articles indexed in MEDLINE (1951-March 2017) and EMBASE (1974-March 2017). Articles were required to be prospective studies of a single over-the-counter cleanser or washing intervention in AV with an objective AV outcome measurement published in a peer-reviewed journal. RESULTS AND CONCLUSIONS: Fourteen prospective studies representing 671 participants were included in this review. Modalities investigated included face washing frequency, true soap/syndet cleansing bars, antiseptic cleansers, alpha and beta-hydroxy (i.e. salicylic) acid cleansers, and several proprietary formulations. Given the low number of well-performed clinical studies of cleansers and washing, it is difficult to formulate reliable recommendations. We hope that our findings highlight the necessity of further investigation in this area. PMID- 29460656 TI - Are skin equipment for assessing childhood eczema any good? AB - AIM: Symptomatology and severity of atopic dermatitis (AD) can be objectively measured with equipment. This study aimed to compare skin measurements and investigate their correlations with various clinical severity scores. METHODS: Skin hydration (SH), transepidermal water loss (TEWL), pH, erythema, pigmentation and ITA (individual typology angle) were measured (using Delfin, Courage+Khazaka and Mettler Toledo equipment), and correlated with Patient-Oriented Eczema Measure (POEM, a short-term subjective-symptom score), Scoring Atopic Dermatitis (SCORAD, a short-term subjective-symptom and objective-sign score), Nottingham Eczema Severity Score (NESS, a long-term subjective-symptom score), Children Dermatology Life Quality Index (CDLQI, a short-term subjective-symptom score) with Spearman's rho coefficient. RESULTS: 80 sets of clinical scores from eczema patients (mean age: 10.8 +/-4.9years; 44.6% male) were evaluated. The POEM, objective SCORAD, CDLQI correlated well with each other. Skin pH ranged from 4.3 7.0 (mean 5.7+/-0.61). Skin pH, were correlated with Objective SCORAD components, including area (rho= 0.269, p = 0.036), erythema (rho= 0.302, p = 0.018) and lichenification (rho = 0.365, p = 0.026) and with the usage frequency of topical antibiotics. Skin pH was also correlated with other skin measurements, including SH (Delfin equipment: rho=-0.38, p < 0.001). SH and TEWL as measured by Delfin equipment correlated better with a number of symptoms and signs than Courage+Khazaka equipmnt. Other clinical measurements including erythema, melanin, and skin colour did not demonstrate strong correlations with clinical symptom scores. CONCLUSION: Skin pH (using Mettler Toledo), SH and TEWL (using Delfin equipment) correlated well with various clinical symptomatology scores. Less acidic pH appears to be associated with worse clinical scores of symptomatology, and increase usage of topical antibiotics, These findings not only support the supplementary usage of equipment in aiding objective documentation of clinical symptomatology in eczema therapeutic research but also the advocacy of maintaining more acidic skin and avoiding alkaline soap and emollient products. PMID- 29460657 TI - Introductory paragraph. PMID- 29460659 TI - Video assisted patient education improves compliance with follow up and depression scores in Inflammatory Bowel Diseases. AB - OBJECTIVES: Patients with inflammatory bowel diseases (IBD) have to deal with a poor quality of life (QOL) and psychomorbidity resulting from an incurable illness. We aimed to study the effect of patient education on QOL, compliance, anxiety and depression in IBD. METHODS: Patients were prospectively enrolled over two years beginning July 2014 and divided into an interventional and usual care group. Both received the standard of care, but the former in addition received an 8 min session of video-assisted education. Compliance to drugs was defined as drug intake of > 80% of the prescribed dose, and adherence to scheduled follow up visits were also compared. Self-administered questionnaires namely Short IBD questionnaire (SIBDQ), Beck Anxiety and Depression Inventory (BAI, BDI-II), Hospital Anxiety and Depression Scale (HADS) were used to assess QOL, anxiety and depression respectively at baseline, 6 months and 1 year. RESULTS: Of the 91 patients enrolled, 84 [92.3%; male = 66 (78.57%)] completed the follow up. Significantly more patients were compliant to follow up visits in the intervention and usual care groups respectively at 6 months (88.4% versus 65.8% respectively; p < 0.01) and 1 year (72.1% versus 46.3% respectively; p < 0.01). The median (IQR) scores for HADS-Depression over 1 year were significantly better in the interventional group than usual care (p < 0.049). The differences in SIBDQ, BDI-II, BAI, HADS-Anxiety and compliance to drug therapy between the groups did not reach statistical significance. CONCLUSION: Video assisted patient education improved compliance to follow up visits and depression scores in IBD. Further modifications in the educational video content and delivery might improve compliance to drug therapy, QOL and anxiety scores. PMID- 29460660 TI - Early repolarization pattern in the coronary slow flow phenomenon. AB - BACKGROUND: The coronary slow flow phenomenon (CSFP) is well-documented, and the early repolarization pattern (ERP) has recently been shown to be a risk factor for the development of malignant ventricular arrhythmias. METHODS: Those with true CSFP were included as cases and those with normal angiograms were included as controls. We assessed J-point elevation on surface electrocardiograms (ECGs) and defined ERP as notching or slurring of the terminal portion of the QRS takeoff. RESULTS: We enrolled 115 cases (33 females, 82 males; mean age, 51.9 +/- 11.5 years) and 45 controls (13 females, 32 males; mean age, 50.8 +/- 11.7 years). ERP was more common among cases than among controls (65% vs. 28%, p = .001). Compared with the controls, cases were more likely to have J-point elevation in the inferior leads (25% vs. 13%, p = .002), in the D1 to aVL leads (22% vs. 15%, p = .001), and in the lateral leads (17.3% vs. 0%), p = .001). Notching was also significantly more common in cases than in controls (26.0% vs. 2.2%, p = .0001). Finally, concave/ascendant ST segment (33.9% vs. 5.2%, p = .006), horizontal/non-ascendant ST segment (14.7% vs. 1.7%, p = .054), and horizontal/non-ascendant ST segment and notching (15.6% vs. 2.2%, p = .012) patterns were more common in cases than in controls. CONCLUSIONS: We report that CSFP is associated with J-wave and slurring ERPs. However, the clinical significance of these changes needs to be clarified. PMID- 29460661 TI - Effective environmental factors on geographical distribution of traffic accidents on pedestrians, downtown of Tehran City. AB - The aim of this study was to geographically analyse the traffic casualties in pedestrians in downtown of Tehran City. Study population consisted of pedestrians who had traffic injury accidents from April 2014 to March 2015 in Tehran City. Data were extracted from the offices of traffic police and municipality. For analysis of environmental factors and site of accidents, Ordinary Least Square (OLS) regression models and Geographically Weighted Regression (GWR) were used. All pedestrian accidents including 514 accidents were assessed in this study in which the site of accidents included arterial streets in 370 (71.9%) cases, collector streets in 133 cases (25.2%) and highways in 11 cases (2.1%). Geographical units of traffic accidents in pedestrians had statistically significant relationship with the number of bus stations, number of crossroads and recreational areas. Neighbourhoods close to markets are considered as the most dangerous places for injury in traffic accidents. PMID- 29460662 TI - Metabolic disposition of WTX101 (bis-choline tetrathiomolybdate) in a rat model of Wilson disease. AB - 1. WTX101 (bis-choline tetrathiomolybdate) is an investigational copper (Cu) protein-binding agent developed for the treatment of Wilson disease (WD), a rare genetic disorder caused by mutations in the ATP7B Cu-transporter and resulting in toxic Cu accumulation. 2. Mass balance of a single intravenous WTX101 dose, measured as molybdenum (Mo), was assessed over 168 h in control (Long Evans Agouti [LEA]) and Long-Evans Cinnamon (LEC) rats, a WD model. 3. In LEC rats, Mo was partially excreted (up to 45%); 29% by renal clearance, and faecal clearance, still ongoing at 168 h, accounted for 16%. In contrast, in LEA rats, Mo was almost fully excreted (~87%); 79% was renally cleared with only 7% faecal excretion. 4. In LEC rats, the proportion of faecal to renal Mo excretion was enhanced (4:6) compared to controls (1:9). 5. Substantially more Mo was found in LEC liver and kidney compared with LEA tissues, in line with tissue Cu distribution. 6. These findings are consistent with the WTX101 mechanism of action: in the WD model, excess Cu is removed from hepatic metallothionein and retained within the stable tetrathiomolybdate-Cu-albumin tripartite complex, preventing tetrathiomolybdate degradation and resulting in less urinary elimination and greater faecal excretion than in controls.

PMID- 29460665 TI - Under the British Roof: The British Contribution to the Development of Hospice and Palliative Care in Poland. AB - The article focuses on British contribution to the development of palliative and hospice care in Poland in the 1980s and beyond. It is based on archival research in the hospices in Cracow and Poznan and broad-scoped Polish journals' review. The social background of the hospice movement in Poland is described. We explore the role of inspiration and help of Dame Cicely Saunders and other British leaders in the transfer of British hospice philosophy and practice of palliative care to the medical community in Poland. This study demonstrates the importance of institutions for the formal exchange of medical information. PMID- 29460666 TI - Effects of Common Ear Drops on Tympanic Membrane Healing in Rats. AB - Objective Ciprofloxacin + dexamethasone ear drops have been associated with higher rates of tympanic membrane perforations than ofloxacin. This was thought to be an effect of the steroid; however, ciprofloxacin (sans steroid) has been found to be more toxic to tympanic membrane fibroblasts than ofloxacin in vitro. This study aimed to compare the effect of these agents on tympanic membrane healing in vivo. Study Design Controlled animal study. Setting Academic research laboratory. Methods Perforations were created in 54 rats with a carbon dioxide laser. Rats were randomized to 6 groups (9/group), with 1 ear receiving ofloxacin, ciprofloxacin, dexamethasone, ofloxacin + dexamethasone, ciprofloxacin + dexamethasone, or neomycin, and the contralateral ear receiving saline twice daily for 10 days. Healing was assessed over 40 days. Results Ofloxacin did not delay healing relative to saline. All other treatments delayed healing relative to ofloxacin at day 10 ( P < .0001). Dexamethasone and ofloxacin + dexamethasone delayed healing up to day 14 ( P < .0001). Neomycin and ciprofloxacin + dexamethasone further delayed healing up to day 28 ( P = .009) and day 35 ( P = .043), respectively. All eardrums healed by day 10 with ofloxacin, day 20 with ciprofloxacin, day 28 for dexamethasone, and day 35 for ofloxacin + dexamethasone. At day 40, 2 of 9 ciprofloxacin + dexamethasone-treated eardrums had not healed. All saline-treated eardrums in the ofloxacin, ciprofloxacin, dexamethasone, and ofloxacin + dexamethasone groups were healed by day 14, but this was delayed to day 20 in the ciprofloxacin + dexamethasone group ( P = .007). Conclusions Ototopical quinolones delay rat tympanic membrane healing in a drug-specific manner, with ciprofloxacin having a greater impact than ofloxacin. This effect is potentiated by steroids.

PMID- 29460668 TI - Personal Control Over Decisions to Participate in Research by Persons With Histories of Both Substance Use Disorders and Criminal Justice Supervision. AB - Individuals must feel free to exert personal control over decisions regarding research participation. We present an examination of participants' perceived personal control over, as well as reported pressures and threats from others, influencing their decision to join a study assessing the effectiveness of extended-release naltrexone in preventing opioid dependence relapse. Most participants endorsed a strong sense of control over the decision; few reported pressures or threats. Although few in number, participants' brief narrative descriptions of the pressures and threats are illuminating and provide context for their perceptions of personal control. Based on this work, we propose a useful set of tools to help ascertain participants' sense of personal control in joining research. PMID- 29460669 TI - Treatment Times in Salivary Gland Cancer: National Patterns and Association with Survival. AB - Objective To characterize treatment times in salivary cancer; associate treatment times with patient, tumor, and treatment characteristics; and examine the association of treatment times and overall survival. Study Design Retrospective cohort. Setting Commission-on-Cancer Accredited Hospitals 2004-2013. Subjects and Methods In total, 5953 patients with salivary cancer included in the National Cancer Database were identified. For each treatment interval, patients in the fourth quartile ("prolonged") were compared to patients in the first and second quartiles ("not prolonged"). Patient, tumor, and treatment characteristics were associated with prolonged times via multivariable binary logistic regression. Prolongation of each interval was associated with overall survival via multivariable Cox proportional hazards regression, controlling for clinically relevant factors. Results Median durations for diagnosis-to-treatment initiation, surgery-to-radiation treatment (RT), RT duration, total treatment package, and diagnosis-to-treatment end were 31, 44, 47, 92, and 110 days, respectively. Race, insurance status, comorbidities, age, T and N stage, facility volume and location, and a facility care transition from diagnosis to initial treatment were associated with prolonged treatment time. Prolonged RT duration was associated with decreased overall survival (OS) (62% vs 75% 5-year OS, HR = 1.26 [95% confidence interval (CI), 1.09-1.47]; P = .002), but prolonged diagnosis-to treatment initiation, surgery-to-RT, total treatment package, and diagnosis-to treatment end intervals were not (70% vs 67% 5-year OS, HR = 1.11 [95% CI, 0.92 1.34], P = .284; 72% vs 68%, HR = 0.93 [95% CI, 0.79-1.09], P = .370; 70% vs 70%, HR = 1.00 [95% CI, 0.84-1.20], P = .974; 66% vs 71%, HR = 0.99 [95% CI, 0.84 1.18], P = .920, respectively). Conclusion The median durations identified here can serve as reference points. Radiation therapy duration is associated with overall survival in salivary cancer and could be considered a quality indicator. PMID- 29460670 TI - Opioid Prescribing Patterns among Otolaryngologists. AB - Objectives To evaluate national trends in opioid prescribing patterns by otolaryngologists for postoperative pain control after common otolaryngologic procedures. Study Design Cross-sectional; survey. Subjects and Methods A survey to determine opioid prescribing patterns for the treatment of postoperative pain following common otolaryngologic procedures was distributed to all members of the American Academy of Otolaryngology-Head and Neck Surgery. Results The most common pain medication prescribed for adults postoperatively was hydrocodone acetaminophen (73%), followed by oxycodone-acetaminophen (39%). The most common pain medication prescribed postoperatively for children was acetaminophen (67%), followed by nonsteroidal anti-inflammatory drugs (65%). Overall, there was a wide variation in quantity of opioids prescribed for each surgery, ranging from 0 to more than 60 doses. Mean opioid prescriptions were greatest for tonsillectomy (37 tablets) and least for direct laryngoscopy (5.3 tablets). Conclusion This study identifies nationwide variations in opioid prescribing patterns among otolaryngologists. While otolaryngology is a relatively small specialty, we still have an obligation to work with all physicians to help combat the current opioid epidemic. By evaluating nationwide postoperative pain regimens, we are moving closer toward understanding how to reduce the opioid burden. PMID- 29460671 TI - Targeted delivery of miRNA-204-5p by PEGylated polymer nanoparticles for colon cancer therapy. AB - AIM: miRNAs have been recognized for their potential in cancer therapeutics, and multiple miRNAs were suggested to affect target genes expression. To overcome limitations of free synthetic miRNAs, such as easily degraded in biofluids and limited in cellular uptake, novel miRNAs delivery systems need to be developed. MATERIALS & METHODS: Using surface-functionalizing technique, poly(D,L-lactide-co glycolide)/poly(L-lactide)-block-poly(ethylene glycol)-folate polymer nanoparticle (PLGA/PLA-PEG-FA) loaded with miR-204-5p (FA-NPs-miR-204) was developed. The therapeutic efficacy of FA-NPs-miR-204 was evaluated in the Luc-HT 29 xenograft tumor model in vivo. RESULTS: FA-NPs-miR-204 could be taken up by HT 29 and HCT-116 cells efficiently, resulting in significant inhibitory effect on cell proliferation and promotive effect on cell apoptosis. In vivo study showed that FA-NPs-miR-204 could exert tumor suppressive function in Luc-HT-29 xenograft model. CONCLUSION: Our study demonstrates a convenient miRNA delivery system that targets tumor tissue and exerts tumor suppressive function, thus demonstrating a potential new therapeutic option for colon cancer. PMID- 29460672 TI - Effects of distance and rescue time to medical facilities on traffic mortality utilizing GIS. AB - Although supported by little scientific evidence, the concept of 'golden hour,' which claims that mortality for trauma patients rises significantly over rescue time, plays a vital role in the design of our current trauma system. Only the contrary results could be found by using Fatality Analysis Reporting System data from 2010 to 2012. The results of logistic regression showed that longer total time intervals were associated with lower traffic mortality, with an odds ratio (OR) of 0.993 per minute. Utilizing the closest facility solver in the Geographic Information System, the effect of 'reverse causation' and the difference between trauma centre and non-trauma centre on the time-mortality relationship were discussed. Furthermore, based on the Kentucky Collision Analysis for the Public data from 2010 to 2012, the results of logistic regression showed that the mortality increased with each additional mile to the trauma centre with an OR of 1.011 per mile. PMID- 29460673 TI - Religion, Religious Heterogeneity, and Intimate Partner Violence Among Korean Immigrant Women. AB - This study examined the role of religious affiliations and frequency of religious service attendance-such as church, Bible studies, and temples-as well as religious heterogeneity between couples on intimate partner violence (IPV) among Korean immigrant women in the United States. Through a case-control design, this study compared 64 Korean immigrant IPV victims with 63 Korean immigrant non-IPV victims. This study's findings reveal that for Korean immigrant women, a high frequency of religious service attendance was associated with higher IPV victimization, while their partners' high religious service attendance was associated with lower IPV victimization. When women's partners were religious compared with when they were not religious, they were less likely to perpetrate IPV even when the partners' alcohol consumption frequency increased. Also, when there was a gap between couples regarding frequency of religious attendance, IPV victimization increased. This discussion concludes by suggesting some policy implications based on these findings. PMID- 29460674 TI - Exploring Reproductive Coercion in Relationship Contexts Among Young Adult, Primarily African American Women at Three Women's Health Clinics. AB - Understanding reproductive coercion experiences in marginalized populations is important to assist in tailoring care and services. Reproductive coercion is consistently associated with intimate partner violence (IPV), engaging in sexual risk-taking, and is more commonly reported among non-White women. We conducted a secondary analysis of data from a mixed methods study to examine reproductive coercion in relationship contexts among a sample ( N = 130) of young adult, primarily African American women recruited from three women's health clinics; 12 also participated in an in-depth interview. Thirty-six women (27.7%) reported reproductive coercion in the past year. Past-year reproductive coercion was associated with relationship trust, ( t(128) = -3.01, p = .003), and past-year IPV (Fisher's exact test, p = .005). In the best-fit model, odds of past-year reproductive coercion increased by 4% with each one-point increase in relationship trust score (indicating reproductive coercion increased with lower trust; adjusted odds ratio [AOR] = 1.04; 95% confidence interval [CI] = [1.00, 1.08]), and by more than 4 times with past experience of IPV (AOR = 4.74; 95% CI = [1.07, 20.86]). Qualitative analysis revealed women's awareness of reproductive coercion whether or not they personally experienced it. Those who experienced reproductive coercion identified it as a form of abuse and additionally described experiences of pressure to conceive from the partner's family. Our results support routine screening for IPV and reproductive coercion. Furthermore, the intersection of partner reproductive coercion with family pressure related to reproductive decision making should be explored to better inform clinical interventions. PMID- 29460675 TI - Risk Stratification for Postoperative Venous Thromboembolism after Endoscopic Sinus Surgery. AB - Objectives Venous thromboembolism (VTE) contributes to significant patient morbidity, yet the incidence of VTE following endoscopic sinus surgery (ESS) is unknown. Quality improvement criteria are prompting increased standardization of perioperative VTE prophylaxis. Risk stratification for VTE may better define best practice measures to balance limiting VTE development with avoiding unnecessary chemoprophylaxis. Study Design Retrospective cohort study. Setting Tertiary institution. Subjects and Methods Adult patients who underwent ESS without perioperative chemoprophylaxis from 2008 to 2016 were evaluated. Identification of VTE was performed via screening diagnosis and procedure codes and clinical records, with subsequent confirmation of true-positive VTE. Data for individual Caprini scores were abstracted from electronic medical records. The primary outcome was development of VTE within 30 days following ESS relative to the Caprini score. Results A total of 2369 ESS cases were evaluated. While initial screening identified multiple potential VTE events, in-depth medical record review confirmed only 4 true VTE (0.17%). The VTE rate among cases with a Caprini score of <8 (0.09%, 2/2278) was significantly less ( P = .008) than the rate with a score of >=8 (2.2%, 2/91). Beyond overall score, specific risk factors associated with development of postoperative VTE included stroke, central venous access, sepsis, and inpatient status (all P < .025), while prior VTE and hypercoagulability were not associated with postoperative VTE (all P > .5). Conclusions In the absence of perioperative chemoprophylaxis, postoperative VTE following ESS is extremely rare, particularly for patients carrying low-to moderate Caprini scores. Risk stratification based on these data can assist in the design of VTE prophylaxis guidelines for ESS patients. PMID- 29460677 TI - Regulation of Hydroxycinnamic Acid Degradation Drives Agrobacterium fabrum Lifestyles. AB - Regulatory factors are key components for the transition between different lifestyles to ensure rapid and appropriate gene expression upon perceiving environmental cues. Agrobacterium fabrum C58 (formerly called A. tumefaciens C58) has two contrasting lifestyles: it can interact with plants as either a rhizosphere inhabitant (rhizospheric lifestyle) or a pathogen that creates its own ecological niche in a plant tumor via its tumor-inducing plasmid (pathogenic lifestyle). Hydroxycinnamic acids are known to play an important role in the pathogenic lifestyle of Agrobacterium spp. but can be degraded in A. fabrum species. We investigated the molecular and ecological mechanisms involved in the regulation of A. fabrum species-specific genes responsible for hydroxycinnamic acid degradation. We characterized the effectors (feruloyl-CoA and p-coumaroyl CoA) and the DNA targets of the MarR transcriptional repressor, which we named HcaR, which regulates hydroxycinnamic acid degradation. Using an hcaR-deleted strain, we further revealed that hydroxycinnamic acid degradation interfere with virulence gene expression. The HcaR deletion mutant shows a contrasting competitive colonization ability, being less abundant than the wild-type strain in tumors but more abundant in the rhizosphere. This supports the view that A. fabrum C58 HcaR regulation through ferulic and p-coumaric acid perception is important for the transition between lifestyles. PMID- 29460678 TI - A Systematic Review of the Association between Cigarette Smoke Exposure and Chronic Rhinosinusitis. AB - Objectives Cigarette smoking and passive smoke exposure have been associated with chronic rhinosinusitis (CRS). Our goal in this systematic review was to (1) determine if there was a strong correlative effect in large population studies between cigarette smoke exposure and the prevalence of CRS, (2) investigate pathogenic mechanisms of cigarette smoke in the upper airway, and (3) determine if a history of cigarette smoking affects the medical and surgical outcomes of CRS. Data Sources MEDLINE, Embase, Cochrane CENTRAL, Web of Science SCI and CPCI S, and websites. Methods A comprehensive literature review and quantitative meta analysis of studies based on the PRISMA protocol and examining the relationship between cigarette smoke exposure and CRS was performed. A search strategy was developed using various terms such as sinusitis, rhinitis, rhinosinusitis, and smoking. The articles were categorized by (1) epidemiology, (2) pathophysiology, and (3) outcomes. Data regarding study design, population/setting, methods, and bias were collected. Results The initial search generated 2621 titles/abstracts with 309 articles undergoing secondary review and 112 articles for final review. We determined that there is a strong correlation between active and passive cigarette smoke with the prevalence of CRS. Cigarette smoke challenge to sinonasal epithelia results in the release of inflammatory mediators and altered ciliary beat frequency. Pediatric patients exposed to secondhand smoke appear to have particularly poor outcomes. Conclusion There is clear evidence that cigarette smoke is related to CRS, but longitudinal and mechanistic studies are required to determine a causative effect. This information is critical for greater understanding of CRS health outcomes.

AB - Pattern-triggered immunity (PTI) can confer broad defense against diverse microbes and pathogens with disparate lifestyles through the detection of microbial extracellular signatures by surface-exposed pattern recognition receptors. However, unlike recognition of pathogen effectors by cytosolic resistance proteins, PTI is typically not associated with a host-cell programmed cell death response. Although host PTI signaling has been extensively studied, the mechanisms by which it restricts microbial colonization are poorly understood. We sought to gain insight into the mechanisms of PTI action by using bacterial transcriptomics analysis during exposure to PTI. Here, we describe a method for bacterial cell extraction from inoculated leaves that was used to analyze a time course of genome-wide transcriptional responses in the pathogen Pseudomonas syringae pv. tomato DC3000 during early naive host infection and exposure to pre-induced PTI in Arabidopsis thaliana. Our analysis revealed early transcriptional regulation of important bacterial metabolic processes and host interaction pathways. We observed peak induction of P. syringae virulence genes at 3 h postinoculation and that exposure to PTI was associated with significant reductions in the expression of virulence genes. We also observed the induction of P. syringae sulfur starvation response genes such as sulfate and sulfonate importers only during exposure to PTI. PMID- 29460679 TI - AMCP Partnership Forum: Improving Quality, Value, and Outcomes with Patient Reported Outcomes. AB - : Patient-reported outcomes (PROs), which provide a direct measure of a patient's health status or treatment preferences, represent a key component of the shift toward patient-centered health care. PROs can measure the state of a patient's disease-specific and overall health throughout the care continuum, enabling them to have a variety of uses for key health care stakeholders. Currently, PROs are used in drug development, aligning patient and clinician goals in care, quality of-care measures, and coverage and reimbursement decisions. While there have been significant strides by key health care stakeholders to further the development and use of PROs, there are a number of challenges limiting more widespread use. In light of these current challenges and the potential for PROs to improve health care quality and value, on October 19, 2017, the Academy of Managed Care Pharmacy convened a forum of key stakeholders representing patients, payers, providers, government, and pharmaceutical companies to discuss and identify solutions to the current challenges and barriers to further use of PROs. These discussions informed the development of participants' ideal future state in which PROs maximize the goals of all health care stakeholders and the actionable steps required to make the future state a reality. While stakeholders shared unique perspectives throughout the forum, they had consensus on 2 overarching issues: the importance of PROs in defining value, improving patient care, and implementing value-based payment models and the need for strong organizational and operational systems to achieve optimal adoption and use. Participants identified several key challenges in PRO use and adoption: achieving a representative patient population, inclusion of PRO data in medication labels, the necessity for both standardized and customizable PROs, and operational and organizational barriers to collecting and analyzing PROs. To overcome these challenges, participants recommended that manufacturers should engage key stakeholders early and throughout the drug development process to ensure the most valid and representative PROs and patient populations will be included. To streamline the PRO collection process, participants suggested engaging pharmacists and other providers who may have more frequent interaction with patients. Participants also recommended that PRO collection and analysis should use common technology platforms, streamline components of clinician care to reduce workflow, and be integrated with claims data to provider payers a better understanding of patient health in real time. Finally, additional work should be done to develop patient-reported outcome measures that contain relevant measures for all healthcare stakeholders. While significant challenges remain in PRO development and adoption, participants agreed that greater use can only be achieved through collaboration and patient-centered care.

PMID- 29460680 TI - Effect of Piecemeal vs En Bloc Approaches to the Lateral Temporal Bone on Survival Outcomes. AB - Objectives Lateral temporal bone resection (LTBR) has traditionally been performed en bloc in accordance with oncologic principles. Occasionally, this is not possible due to a low tegmen or lateralized vasculature. We sought to determine if outcomes of piecemeal and en bloc LTBR are comparable. Study Design Retrospective review. Setting Two academic medical centers. Subjects and Methods Multi-institutional retrospective cohort study. Current Procedural Terminology codes were used to identify patients with T1 to T3 squamous cell carcinoma of the external auditory canal (EAC) who underwent LTBR from 2005 to 2015. Kaplan-Meier curves were constructed to compare total survival between the 2 treatment approaches. Pairwise comparisons were performed using chi2 and Fisher exact tests (significance at P = .05), as appropriate. Results Twenty-five patients were identified. Ten patients underwent en bloc LTBR; 15 underwent piecemeal LTBR. Median follow-up time was 11 months (range, 1-60 months). There was not a significant difference in overall survival between en bloc (38.9 months; 95% confidence interval [CI], 22.7-55.2) compared to piecemeal (37.5 months; 95% CI, 21.1-53.9) procedures ( P = .519). Estimates of disease-free survival also did not reveal statistically significant differences: estimated mean disease-free survival was 48.1 months (95% CI, 33.7-62.6) in en bloc patients and 32.5 months (95% CI, 17.1-47.8) in piecemeal patients ( P = .246). Conclusion These data suggest that piecemeal resection can be considered for cases of squamous cell carcinoma involving the external auditory canal where anatomic constraints preclude a safe en bloc resection. Larger studies or studies with a longer follow up time may provide improved insight into survival comparisons. PMID- 29460681 TI - Assessment of Disease-Specific and General Patient-Reported Outcome Measures of Hearing Health. AB - Objective To assess disease-specific (Inner EAR) and general (Patient-Reported Outcomes Measurement Information System [PROMIS]) health status in patients reporting hearing loss and whether there is enough correlation between scales such that the general instrument alone could suffice. Study Design Correlation analysis of prospective cohort data. Setting Tertiary care academic medical center. Methods Adults presenting with a chief complaint of hearing loss completed the Inner EAR scale and the PROMIS instrument. Summary statistics, including means, percentiles, and measures of variance, were calculated. The Spearman rho statistic was used to test the null hypothesis that there were no correlations between the Inner EAR composite or global score and PROMIS scores. Results The mean Inner EAR composite score was 35.6, while the global item had a mean score of 4.8. Mean PROMIS-10 scores were 16.0 for physical health and 15.3 for mental health. The global item and social item had mean scores of 3.6 and 3.8, respectively. Inner EAR composite scores were significantly correlated with the PROMIS mental health summary scores (Spearman rho = 0.3, P = .0066) and the PROMIS social item score (Spearman rho = 0.4, P = .0005). The Inner EAR global item was moderately correlated with the PROMIS social item score (Spearman rho = 0.3, P = .0118), while there was no significant correlation between the Inner EAR global item and the PROMIS physical health, mental health, or global item scores. Conclusions Inner EAR and a subset of PROMIS scores have weak to moderate correlations. Disease-specific assessment still confers independent value. PMID- 29460682 TI - Match 2017: Blindsided or Fumbled? AB - The field of otolaryngology has historically enjoyed extreme interest among residency applicants. However, in the past few years, the number of applicants has precipitously dropped, so that there is no longer a significant excess of applications. It remains important for academic programs to promote student interest in otolaryngology, to break down barriers that may dissuade excellent candidates, and to widen the welcome. PMID- 29460683 TI - Writing abilities and the role of working memory in children with symptoms of attention deficit and hyperactivity disorder. AB - The writing abilities of children with ADHD symptoms were examined in a simple dictation task, and then in two conditions with concurrent verbal or visuospatial working memory (WM) loads. The children with ADHD symptoms generally made more spelling mistakes than controls, and the concurrent loads impaired their performance, but with partly different effects. The concurrent verbal WM task prompted an increase in the phonological errors, while the concurrent visuospatial WM task prompted more non-phonological errors, matching the Italian phonology, but not the Italian orthography. In the ADHD group, the children proving better able to cope with a concurrent verbal WM load had a better spelling performance too. The ADHD and control groups had a similar handwriting speed, but the former group's writing quality was poorer. Our results suggest that WM supports writing skills, and that children with ADHD symptoms have general writing difficulties, but strength in coping with concurrent verbal information may support their spelling performance. PMID- 29460685 TI - Prognostic Value of Lymph Node Yield and Density in Head and Neck Malignancies. AB - Objective Studies have suggested that the lymph node yield and lymph node density from selective or elective neck dissections are predictive of patient outcomes and may be used for patient counseling, treatment planning, or quality measurement. Our objective was to systematically review the literature and conduct a meta-analysis of studies that investigated the prognostic significance of lymph node yield and/or lymph node density after neck dissection for patients with head and neck cancer. Data Sources The Ovid/Medline, Ovid/Embase, and NLM PubMed databases were systematically searched on January 23, 2017, for articles published between January 1, 1946, and January 23, 2017. Review Methods We reviewed English-language original research that included survival analysis of patients undergoing neck dissection for a head and neck malignancy stratified by lymph node yield and/or lymph node density. Study data were extracted by 2 independent researchers (S.C. and M.O.). We utilized the DerSimonian and Laird random effects model to account for heterogeneity of studies. Results Our search yielded 350 nonduplicate articles, with 23 studies included in the final synthesis. Pooled results demonstrated that increased lymph node yield was associated with a significant improvement in survival (hazard ratio, 0.833; 95% CI, 0.790-0.879). Additionally, we found that increased lymph node density was associated with poorer survival (hazard ratio, 1.916; 95% CI, 1.637-2.241). Conclusions Increased nodal yield portends improved outcomes and may be a valuable quality indicator for neck dissections, while increased lymph node density is associated with diminished survival and may be used for postsurgical counseling and planning for adjuvant therapy. PMID- 29460684 TI - A negative feedback regulation of MTORC1 activity by the lysosomal Ca2+ channel MCOLN1 (mucolipin 1) using a CALM (calmodulin)-dependent mechanism. AB - Macroautophagy/autophagy is an evolutionarily conserved pathway that is required for cellular homeostasis, growth and survival. The lysosome plays an essential role in autophagy regulation. For example, the activity of MTORC1, a master regulator of autophagy, is regulated by nutrients within the lysosome. Starvation inhibits MTORC1 causing autophagy induction. Given that MTORC1 is critical for protein synthesis and cellular homeostasis, a feedback regulatory mechanism must exist to restore MTORC1 during starvation. However, the molecular mechanism underlying this feedback regulation is unclear. In this study, we report that starvation activates the lysosomal Ca2+ release channel MCOLN1 (mucolipin 1) by relieving MTORC1's inhibition of the channel. Activated MCOLN1 in turn facilitates MTORC1 activity that requires CALM (calmodulin). Moreover, both MCOLN1 and CALM are necessary for MTORC1 reactivation during prolonged starvation. Our data suggest that lysosomal Ca2+ signaling is an essential component of the canonical MTORC1-dependent autophagy pathway and MCOLN1 provides a negative feedback regulation of MTORC1 to prevent excessive loss of MTORC1 function during starvation. The feedback regulation may be important for maintaining cellular homeostasis during starvation, as well as many other stressful or disease conditions. PMID- 29460686 TI - Anatomical Pathology of the Umbilical Cord and Its Maternal and Fetal Clinical Associations in 434 Newborns. AB - Introduction Umbilical cord (UC) abnormalities and their clinical relations in 434 newborns were analyzed. We had previously reported on clinical associations of long and short UCs with any kind of malformation. This study focuses on other UC features (insertion, vessels, entanglements, coiling, and knots) and their associations with clinical characteristics and neonatal prognosis. Methods An observational analytic study was performed on placentas from consecutive deliveries. Ordered logistic regression with bivariate and multivariate analysis was performed to evaluate the relationship between variables of interest concerning UC abnormalities. Results A total of 434 placentas made up the study. UC abnormalities were abnormal insertion, 82 (18.86%); coiling (hypo and hypercoiled), 177 (40.78%); single umbilical artery (SUA), 4 (0.92%); entanglements, 8 (1.84%); true knots, 3 (0.69%); webs in UC base, 9 (2.07%); and right twist, 68 (15.67%). After analyzing maternal and fetal complications during pregnancy, multivariate analysis confirmed the recognized association between malformations and SUA and male gender; further confirmation was also made between hypertensive disorders of pregnancy and true knots. Discussion UC abnormalities associated with undesirable outcomes are varied and should be recognized and described. Clinical factors associated with anatomical UC abnormalities are not completely understood and justify forthcoming studies. PMID- 29460687 TI - Is Graphology Useful in Assessing Major Depression? AB - This study aimed to develop a handwriting analysis protocol for assessing severe major depressive disorder, in order to evaluate whether graphological analysis could be considered an objective tool and hence if it could be useful for clinicians in their early diagnosis. We modified and improved the methodology described by Lorusso et al. by proposing different graphic indexes based both on the literature and on the observation of a preliminary sample of 13 handwritings of patients affected by major depressive disorder. Then, we recruited 80 participants, divided into two groups: clinical sample ( n = 44) and control group ( n = 36). We used Cohen's Kappa to evaluate the reliability of agreement among four professional graphologists and the consensus between the psychiatric assessment and the ratings given by the judges. We found satisfactory results. Using our protocol, we obtained higher values for Cohen's Kappa as compared with Lorusso et al. The agreement among graphologists is K = .62, while the K values for the agreement between psychiatric assessment and graphologists range between .47 and .60. The substantial improvements obtained in comparison with Lorusso et al. are encouraging and support further attempts. PMID- 29460688 TI - Flourishing-at-Work: The Role of Positive Organizational Practices. AB - The first aim of the study was to investigate the effects of flourishing at work (as measured by the Flourishing-at-Work Scale-Short Form) on intention to leave, performance, and organizational citizenship behavior. The second aim was to determine the prevalence of workplace flourishing and to examine differences in the perceived flourishing levels of teachers based on the positive practices they experience in their organization. A sample of 258 secondary school educators in the Gauteng province of South Africa was used in the cross-sectional design. The Flourishing-at-Work Scale-Short Form, Turnover Intention Scale, In-Role Behavior Scale, Organizational Citizenship Behavior Scale, and the Positive Practices Questionnaire were administered. The results showed acceptable psychometric properties for the short scale which measures flourishing. Workplace flourishing negatively predicted intention to leave, while positively predicting in-role performance and organizational citizenship behavior. A total of 44.19% of the population flourished, while 49.22% were moderately mentally healthy and 6.59% languished. Positive organizational practices were associated with flourishing at work. PMID- 29460689 TI - Exploring Characteristics and Health Care Utilization Trends Among Individuals Who Fall in the Health Insurance Assistance Gap in a Medicaid Nonexpansion State. AB - States that did not expand Medicaid under the Affordable Care Act (ACA) in the United States have seen a growth in the number of individuals who fall in the assistance gap, defined as having incomes above the Medicaid eligibility limit (>=44% of the federal poverty level) but below the lower limit (<100%) to be eligible for tax credits for premium subsidies or cost-sharing reductions in the marketplace. The purpose of this article is to present findings from a secondary data analysis examining the characteristics of those who fell in the assistance gap ( n = 166) in Missouri, a Medicaid nonexpansion state, by comparing them with those who did not fall in the assistance gap ( n = 157). Participants completed online demographic questionnaires and self-reported measures of health and insurance status, health literacy, numeracy, and health insurance literacy. A select group completed a 1-year follow-up survey about health insurance enrollment and health care utilization. Compared with the nonassistance gap group, individuals in the assistance gap were more likely to have lower levels of education, have at least one chronic condition, be uninsured at baseline, and be seeking health care coverage for additional dependents. Individuals in the assistance gap had significantly lower annual incomes and higher annual premiums when compared with the nonassistance gap group and were less likely to be insured through the marketplace or other private insurance at the 1-year follow-up. Findings provide several practice and policy implications for expanding health insurance coverage, reducing costs, and improving access to care for underserved populations. PMID- 29460690 TI - Improving mental health knowledge of the Charedi Orthodox Jewish Community in North London: A partnership project. AB - INTRODUCTION: This article describes a successful community-based partnership project between statutory and third-sector services targeting the strictly Orthodox Jewish community (OJC). METHODS: The City and Hackney Black and Minority Ethnic (BME) Access Service (East London NHS Foundation Trust (ELFT)) collaborated with Bikur Cholim, a local third-sector organisation based in the heart of a north London Charedi OJC, to develop a brief culturally tailored psychoeducational group intervention focusing on mental health promotion and prevention. In total, 34 carers in the Charedi OJC were provided with general information on mental health, the availability of support services and self-care. RESULTS: Overall improvements in well-being, increased intentions to access services, particularly talking therapies, and qualitative feedback indicated that the group was very well received. CONCLUSION: The project endorses the value of culturally relevant psychoeducation, enabling suggestions for culturally appropriate service development. PMID- 29460691 TI - A New Needle Holder Design to Facilitate Intracorporeal Knot Tying. AB - PURPOSE: Intracorporeal knot tying in laparoscopic surgery continues to be a problem especially for beginners and inexperienced surgeons. A wide-angle needle holder was designed to make the knot maneuver easier while also ensuring that the knot does not come out of the needle holder. In this study, it was planned to compare the wide-angle needle holder with the classic needle holder in regard to knot tying time. MATERIAL AND METHOD: A total of 11 male volunteers were randomly selected from freshmen students of the faculty of medicine, who had no experience of surgery or laparoscopic surgery. After the required training and practice, candidates were asked to tie 3 knots each in the training box using a classic needle holder and a wide-angle needle holder. Their knot tying times were recorded. RESULTS: Although the students had no experience, it was observed that they tied knots more easily and more comfortably using the wide-angle needle holder. It was found that the knot tying times with the wide-angle needle holder were quite short compared with the classic needle holder in all candidates. This difference was also statistically significant ( P = .01). CONCLUSION: We believe and claim that the use of a wide-angle needle holder during knot tying in laparoscopic surgery can facilitate knot tying and shorten the duration of the knotting, especially for inexperienced surgeons.

AB - Suicide has been the second leading cause of death for 18- to 24-year-olds in the United States since 2011. The stress experienced by undergraduate college students has the potential to increase one's risk for suicide. Resilience theory was used as a theoretical framework to examine the interplay between risk and protective factors. A cross-sectional and correlational design was used to assess the mediating effects of positive thinking and/or social support on suicide resilience in 131 college students 18 to 24 years old who completed an online survey. The study found an indirect effect of self-esteem on suicide resilience through positive thinking and social support indicating that as self-esteem increases, positive thinking and social support also increase, which leads to an increase in resilience. The study also found a direct effect of self-esteem, positive thinking, and social support on suicide resilience. The findings inform the development of tailored interventions to build suicide resilience in college students. PMID- 29460694 TI - Control of exposure to hexavalent chromium concentration in shielded metal arc welding fumes by nano-coating of electrodes. AB - Background Cr(VI) is a suspected human carcinogen formed as a by-product of stainless steel welding. Nano-alumina and nano-titania coating of electrodes reduced the welding fume levels. Objective To investigate the effect of nano coating of welding electrodes on Cr(VI) formation rate (Cr(VI) FR) from a shielded metal arc welding process. Methods The core welding wires were coated with nano-alumina and nano-titania using the sol-gel dip coating technique. Bead on plate welds were deposited on SS 316 LN plates kept inside a fume test chamber. Cr(VI) analysis was done using an atomic absorption spectrometer (AAS). Results A reduction of 40% and 76%, respectively, in the Cr(VI) FR was observed from nano-alumina and nano-titania coated electrodes. Increase in the fume level decreased the Cr(VI) FR. Discussion Increase in fume levels blocked the UV radiation responsible for the formation of ozone thereby preventing the formation of Cr(VI). PMID- 29460695 TI - High seroprevalence and peripheral spatial distribution of visceral leishmaniasis among domestic dogs in an emerging urban focus in Central Brazil: a cross sectional study. AB - The Brazilian municipality of Rondonopolis is an emerging urban focus of intense transmission of visceral leishmaniasis (VL), where few investigations have addressed canine reservoirs. This study assessed the seroprevalence and spatial distribution of canine visceral leishmaniasis (CVL) in the urban area of Rondonopolis. A CVL serosurvey was conducted between October 2016 and February 2017 using an immunochromatographic rapid test and enzyme-linked immunosorbent assay. Domestic dogs were sampled from 25 heterogeneous regions previously defined by the Spatial 'K'luster Analysis by Tree Edge Removal algorithm, which considered the socioeconomic and environmental features from the last demographic census. The CVL spatial distribution was analyzed by kernel density estimation (KDE) and spatial scan statistic. All the autochthonous human VL cases reported between 2014 and 2016 were georeferenced. Of the 600 dogs tested, 115 were seropositive in both tests. The overall CVL prevalence was 19.2% (95%CI: 16.1 22.3%), which varied widely among the evaluated regions (0.0-35.1%). Almost 25% of the sampled households (n = 405) had at least one infected dog. KDE demonstrated that positive CVL households were concentrated in the peripheral areas of the city. Spatial scan statistics detected a spatial cluster with significantly low CVL prevalence in the central region (relative risk = 0.37; p = 0.04), where only one human VL case was reported. Thus, we demonstrated a high prevalence of CVL in domestic dogs from diverse socioeconomic and environmental urban contexts in Rondonopolis. The CVL cases were peripherally distributed and occurred more frequently in areas that had reported human VL. PMID- 29460696 TI - National health inequality monitoring: current challenges and opportunities. AB - National health inequality monitoring needs considerably more investment to realize equity-oriented health improvements in countries, including advancement towards the Sustainable Development Goals. Following an overview of national health inequality monitoring and the associated resource requirements, we highlight challenges that countries may encounter when setting up, expanding or strengthening national health inequality monitoring systems, and discuss opportunities and key initiatives that aim to address these challenges. We provide specific proposals on what is needed to ensure that national health inequality monitoring systems are harnessed to guide the reduction of health inequalities. PMID- 29460697 TI - Use of information communication technology and stress, burnout, and mental health in older, middle-aged, and younger workers - results from a systematic review. AB - The aim of this systematic review is to summarise quantitative studies in occupational settings observing the association between Information communication technology (ICT) and stress, and burnout, considering age as an effect modifier. A systematic review using PRISMA guidelines was conducted through the following bibliographic databases: PubMed, Web of Science, Psycinfo, and the Cochrane Library. Inclusion criteria were occupational settings and content relevant to our research question. Risk of bias was assessed using the Newcastle-Ottawa scale. Two interventional, 4 cohorts, and 29 cross-sectional studies were found. ICT use in occupational settings was associated with stress seen in cross sectional studies, but not in interventional studies. There was a concordant association with ICT and burnout in different study designs. Overall, there were no linear trends between age and technostress. We suggest that the observed associations were mostly present in the middle-aged working population and that these associations need to be supported in further studies. PMID- 29460698 TI - "Life Goes On." Everyday Tasks, Coping Self-Efficacy, and Independence: Exploring Older Adults' Recovery From Hip Fracture. AB - Older adults face many challenges in the first few months after hip fracture. Rehabilitation holds promise to assist the recovery process. Therefore, we used semistructured interviews to explore older adults' and allied health professionals' acceptance of a rehabilitation intervention for hip fracture, and we described perceptions of the early recovery period (<4 months). Interviews were recorded and transcribed verbatim; three authors independently read the transcripts multiple times and together developed themes guided by Interpretive Description. Older adults described the intervention as acceptable and provided valuable feedback for its future implementation. Older adults also provided reflections on their experience of fracture recovery. Themes that emerged included physical limitations and loss of independence, the long recovery time, and coping with additional complications of living with multimorbidity. To overcome challenges, older adults identified the need for social support and physical activity, balanced by their own personal outlook. PMID- 29460699 TI - Systemic Lupus Erythematosus (SLE) Responder Index response is associated with global benefit for patients with SLE. AB - A post-hoc analysis of pooled data from two Phase IIb trials (sifalimumab; NCT01283139, anifrolumab; NCT01438489) assessed the clinical significance of a Systemic Lupus Erythematosus (SLE) Responder Index (SRI(4)) response (Week 52) for 736 patients with moderate to severe SLE disease activity (study entry). SRI(4) responders achieved significantly greater improvements in clinical outcome measures (including percentages of patients with a >= 7-point reduction in SLE Disease Activity Index (SLEDAI)-2000 (2K), British Isles Lupus Assessment Group "A" or "2B" flare rate, and oral corticosteroid reduction to <=7.5 mg/day; change from baseline in Physician's Global Assessment; and numbers of SLEDAI-2K organ domains with improvement), as well as in patient-reported outcomes (Patient's Global Assessment, Functional Assessment of Chronic Illness Therapy-Fatigue; Short-Form 36 Health Survey Physical Component Summary, Mental Component Summary, Vitality domain scores) vs. nonresponders. Of patients with abnormal serologies, SRI(4) responders had numerically greater improvements (baseline to Week 52) in anti-double-stranded DNA concentrations vs. nonresponders ( p = 0.051), but there were no differences in C3/C4 concentration changes between the two groups. These results confirm previous findings in a different cohort, indicating that an SRI(4) response is associated with global clinical benefit. PMID- 29460700 TI - The lupus patient with positive rheumatoid factor. AB - Background Patients with systemic lupus erythematosus (SLE) may form clusters with clinical manifestations and autoantibodies. Objective The objective of this report is to study whether SLE patients with positive rheumatoid factor (RF) have a special clinical and/or serological profile. Methods A retrospective study of 467 SLE patients seen at a single rheumatology unit was conducted. Epidemiological data (age, gender, age at disease onset, ethnic background and tobacco use), clinical data (malar rash, photosensitivity, oral ulcers, discoid lesions, serositis, glomerulonephritis, convulsions, psychosis, hemolytic anemia, leukopenia, lymphocytopenia, arthritis and hypothyroidism) and serological profile (anti-dsDNA, anti-Ro/SS-A, anti-La/SS-B, anti-RNP, anti-Sm, IgG aCL, IgM aCL, lupus anticoagulant, direct Coombs and RF) were collected. Patients with positive and negative RF were compared. Results RF was found in 24.9% of the sample. In univariate analysis, RF was positively associated with butterfly rash ( p = 0.04), anti-Ro ( p = 0.03), anti-Sm antibodies ( p = 0.01) and hypothyroidism ( p = 0.01) and negatively associated with glomerulonephritis ( p = 0.003). Logistic regression showed that only glomerulonephritis ( p = 0.03; OR = 0.45; 95% CI = 0.21-0.93) and anti-Ro ( p = 0.009; OR = 2.3; 95% CI = 1.24 4.57) were independent associations. Conclusion In our sample RF was associated with protection from glomerulonephritis and with higher prevalence of anti-Ro antibodies. PMID- 29460701 TI - Anti-dsDNA titre in female systemic lupus erythematosus patients: relation to disease manifestations, damage and antiphospholipid antibodies. AB - Background Attempts are ongoing to unveil unresolved queries about anti-double stranded deoxyribonucleic acid (anti-dsDNA), their precise pathogenic effects and to what extent blocking them would be a useful therapeutic goal. Objectives The aim of the present study was to determine the anti-dsDNA antibodies titre in systemic lupus erythematosus (SLE) patients and investigate their relation to the disease characteristics, activity, damage and antiphospholipid autoantibodies (aPL). Methods Seventy female SLE patients and 35 age- and sex-matched controls were included. The anti-dsDNA level and aPL were measured. Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) and Systemic Lupus International Collaborative Clinics/American College of Rheumatology Damage Index (SLICC/ACR DI) were assessed. Results The mean age of the patients was 27.5 +/- 5.1 years, disease duration 7.7 +/- 5.4 years, and SLEDAI and SLICC/ACR-DI scores were 6.8 +/- 8.04 and 1.2 +/- 1.3, respectively. Anti-dsDNA was positive in 61.4% of the patients and the titre (133.2 +/- 100.5 IU/ml) was significantly higher compared to controls (22.03 +/- 17.2 IU/ml) ( p < 0.0001). The anti-dsDNA level was significantly increased in those with musculoskeletal manifestations ( p = 0.007) and positive anti-beta2 glycoprotein (anti-beta2GP) ( p = 0.037) and decreased in those with neuropsychiatric manifestations ( p = 0.004) and those receiving cyclophosphamide (CYC) ( p = 0.013). The anti-dsDNA level tended to be higher in active patients. The anti-dsDNA titre significantly correlated with the erythrocyte sedimentation rate ( p = 0.001), anticardiolipin IgG and IgA antibodies ( p = 0.008) and anti-beta2GP IgG ( p = 0.03) and IgA ( p = 0.002) and inversely with the total leucocytic count ( p < 0.0001) and SLICC/ACR-DI ( p = 0.001). Conclusion Anti-dsDNA is remarkably increased in SLE patients especially those with musculoskeletal manifestations and aPL. A protective role seems likely in those with neuropsychiatric manifestations and those receiving CYC and may form a shield against disease tissue damage. PMID- 29460702 TI - Comparison between disease onset patterns of Egyptian juvenile and adult systemic lupus erythematosus (single centre experience). AB - Background Systemic lupus erythematosus (SLE) is a complex autoimmune disease that occurs worldwide in both children and adults, with different disease manifestations, activity and severity between them. Objectives To analyse the difference in disease onset patterns and activity in Egyptian children and adults with SLE. Methods A retrospective cohort study conducted on 298 Egyptian SLE patients, 215 adults (a-SLE) (>18 years) and 83 children (j-SLE) (<=18 years). Disease onset, clinical manifestations and laboratory investigations were recorded. The systemic lupus erythematosus disease activity index (SLEDAI) was used to assess disease onset activity; renal biopsy was performed for all cases affected with renal symptoms. Results A total of 215 a-SLE (F/M: 14.4/1), mean age 29.65 +/- 10.235 years, and 83 j-SLE (F/M: 5.4/1), mean age at diagnosis 12.63 +/- 3.112 years. The most frequent initial a-SLE symptoms were constitutional (88.8%), mucocutaneous (71.2%), haematological (64.2%), articular (62.3%), renal (43.7%), vascular (15.3%), serositis (14.4%) and finally central nervous system (11.6%). There were no significant differences between a-SLE and j SLE with regard to constitutional, mucocutaneous, renal, vascular and serositis manifestations, which were 92.8%, 74.7%, 53%, 16.9% and 10.8%, respectively, but the j-SLE haematological (88%) and central nervous system (30.1%) manifestations were significantly higher than a-SLE and articular manifestations were significantly lower in j-SLE (14.5%) than a-SLE. Antinuclear antibodies were positive for 95.3% of a-SLE and 97.6% of j-SLE. Anti-dsDNA was positive for 84.7% a-SLE and was significantly higher in j-SLE (92.8%). The SLEDAI score was 12.23 +/- 4.966 in a-SLE and was significantly higher in j-SLE (27.13 +/- 19.968). International Society of Nephrology lupus nephritis classes III and IV (42.4%) were the commonest findings in a-SLE; however, classes I and III (57.9%) were the commonest in j-SLE. Conclusions SLE had a wide variety of clinical and immunological manifestations, with some similarity and differences between a-SLE and j-SLE; juvenile onset lupus had a higher SLEDAI with more aggressive initial manifestations than a-SLE.

AB - Aim To offer a practice insight for the management of chemoradiation toxic mucositis. Method Review chemoradiation toxic mucositis, its pathobiology and breadth of symptom presentation. Review mucositis guidelines and guideline supported anti-mucositis therapies. Offer guidance on guidelines and an abbreviated review of high potency cross-linked sucralfate for management of chemoradiation toxic mucositis. Result There are six major mucositis guidelines but only one that is current and regularly updated. Guidelines from the Multinational Association Supportive Cancer Care suggest 14 interventions gleaned from controlled trials, 12 of which are off-label uses of therapies that offer statistically significant but incrementally beneficial outcomes. Several evidence based limitations of guidelines are discussed. Data on high potency polymerized cross-linked sucralfate confirming complete prevention and rapid (2-3 days) elimination, sustained throughout cancer treatment is verified as high quality evidence in accordance to standards adopted by Agency for Healthcare Research and Quality. A 96-97% reduction in mucositis duration qualifies as a positive Glasziou treatment effect, which is discussed as an additional measure of evidence-based medicine. Conclusion Statistically significant but fractional treatment effects of guideline-supported interventions are not likely to substantially alter the course of mucositis when it occurs nor completely prevent its onset. Complete prevention and rapid sustained elimination should be the goal, therefore high potency polymerized cross-linked sucralfate may be useful. Where guidelines fail, institution-based protocols led by oncology pharmacists could succeed. In an effort to eliminate toxic mucositis, enhance compliance to chemoradiation regimens, and improve survival, such protocols for practice may verify pharmacoeconomic benefits, if any, in using high potency polymerized cross linked sucralfate to manage toxic mucositis.

PMID- 29460705 TI - A single center retrospective cohort study comparing low-molecular-weight heparins to direct oral anticoagulants for the treatment of venous thromboembolism in patients with cancer - A real world experience. AB - Introduction Low-molecular-weight heparins are the standard treatment for cancer associated thrombosis. Recently, direct oral anticoagulants are a new option for thrombosis treatment; however, data supporting the use of direct oral anticoagulants for cancer-associated thrombosis are limited. Objectives The primary objective of this study was to determine the rate of recurrent cancer associated thrombosis and major bleeding within 6 months of starting either low molecular-weight heparin or direct oral anticoagulant for treatment of cancer associated thrombosis. Secondary objectives were to determine the rates of clinically relevant-non-major bleeding and all-cause mortality. Patients/methods This is a retrospective cohort study including adults with cancer-associated thrombosis treated with low-molecular-weight heparin or direct oral anticoagulant between 2010 and 2016 at the Ohio State University. Medical records were reviewed for 6 months after initiation of anticoagulation or until the occurrence of recurrent cancer-associated thrombosis, major bleeding, cessation of anticoagulation of interest, or death, whichever occurred first. Results Four hundred and eighty patients were included (290 low-molecular-weight heparin and 190 direct oral anticoagulant). Patients treated with direct oral anticoagulant were found to carry "lower risk" features including cancer with lower VTE risk and lower rate of metastatic disease. After adjustment for baseline differences, there was no significant difference in the rate of recurrent cancer-associated thrombosis (7.2% low-molecular-weight heparin vs 6.3% direct oral anticoagulant, p = 0.71) or major bleeding (7.6% low-molecular-weight heparin vs 2.6% direct oral anticoagulant, p = 0.08). Conclusions Our study demonstrates that in a select population of cancer patients with VTE, direct oral anticoagulant use can be as effective and safe compared to the standard therapy with low-molecular weight heparin. PMID- 29460706 TI - Using a treatment diary to improve the medication adherence in patients with chronic myeloid leukaemia. AB - Purpose The aim of this study was to verify whether the distribution of a treatment diary by a pharmacist could influence the adherence to oral treatment with imatinib, nilotinib, and dasatinib in patients with chronic myeloid leukaemia. Methods The level of adherence was calculated using the received daily dose/prescribed daily dose ratio and compared between patients who used a diary and those who did not. Results Forty-four (35.8%) of 123 patients with chronic myeloid leukaemia completed the diary: 20 (45.4%) receiving imatinib, 17 (38.6%) receiving nilotinib, and seven (15.9%) receiving dasatinib. Treatment adherence with the diary calculated using received daily dose/prescribed daily dose method was 93.6% (imatinib 94.9%, nilotinib 91.1%, and dasatinib 95.8%). Adherence during the period without a diary was 86.5% (84.9, 87.4, and 90%). Adherence was significantly greater with than without a diary (p < 0.0001). Conclusions The findings of this study that, in the case of chronic diseases, direct pharmacist patient contact is important in order to maintain high levels of adherence, and a treatment diary is a valid means of doing this. According to these data, it is necessary to support similar patient-oriented programmes in order to ensure high levels of adherence and optimize drug management. PMID- 29460707 TI - Using Microscale Thermophoresis to Characterize Hits from High-Throughput Screening: A European Lead Factory Perspective. AB - High-throughput screening (HTS) is a proven method for discovering new lead matter for drug discovery and chemical biology. To maximize the likelihood of identifying genuine binders to a molecular target, and avoid wasting resources following up compounds with unproductive/nonspecific mechanisms of action, it is important to employ a range of assays during an HTS campaign that build confidence of target engagement for hit compounds. Biophysical methods that measure direct target/compound engagement have established themselves as key techniques in generating this confidence, and they are now integral to the latter stages of HTS triage at the European Lead Factory (ELF). One relatively new technique that the ELF is using is microscale thermophoresis (MST), which measures the differences in rate of movement through a temperature gradient that are caused when single molecular species form complexes. Here we provide an overview of the MST assay development workflow that the ELF employs and a perspective of our experience to date of using MST to triage the output of HTS campaigns and how it compares and contrasts with the use of other biophysical techniques.

AB - In this study, collagen/alginate/hydroxyapatite beads having different proportions were prepared as bone fillers for the restoration of osteological defects. Ionic liquid was used to dissolve the collagen and subsequently the solution was mixed with sodium alginate solution. Hydroxyapatite was added in different proportions, with the rationale to enhance mechanical as well as biological properties. The prepared solutions were given characteristic bead shapes by dropwise addition into calcium chloride solution. The prepared beads were characterized using FTIR, XRD, TGA and SEM analysis. Microhardness testing was used to evaluate the mechanical properties. The prepared beads were investigated for water adsorption behavior to ascertain its ability for body fluid uptake and adjusted accordingly to the bone cavity. Drug loading and subsequently the antibacterial activity was investigated for the prepared beads. The biocompatibility was assessed using the hemolysis testing and cell proliferation assay. The prepared collagen-alginate-HA beads, having biocompatibility and good mechanical properties, have showed an option of promising biologically active bone fillers for bone regeneration.

AB - Physicians are deeply involved in Canadian medicare because it is through medicare that they are paid. However, from its origins to the present physicians as a profession - have not been strong supporters of medicare. Fearing loss of income and individual autonomy, they have frequently opposed it with criticisms, strikes, threatened job action and lawsuits. Some opponents are unaware that medicare was a boon to physician income, and many fail to connect medicare with responsibility for improving the health status of the country. This paper will trace physician involvement, support and opposition to medicare from its inception to the present, with special attention to small physician organizations that have supported medicare. It will close with a proposal for how doctors could display greater stewardship.

PMID- 29460712 TI - Rhythmic low-field magnetic stimulation may improve depression by increasing brain-derived neurotrophic factor. AB - BACKGROUND: Low-field magnetic stimulation (LFMS) has mood-elevating effect, and the increase of brain-derived neurotrophic factor (BDNF) is associated with antidepressant treatment. We evaluated the effects and association with BDNF of rhythmic LFMS in the treatment of major depressive disorder (MDD). METHODS: A total of 22 MDD patients were randomized to rhythmic alpha stimulation (RAS) or rhythmic delta stimulation (RDS), with 5 sessions per week, lasting for 6 weeks. Outcomes assessments included the 17-item Hamilton Depression Rating Scale (HAMD 17), the Hamilton Anxiety Rating Scale (HAMA), and the Clinical Global Impressions-Severity scale (CGI-S) at baseline and at weeks 1, 2, 3, 4, and 6. Serum BDNF level was measured at baseline and at weeks 2, 4, and 6. RESULTS: HAMD 17, HAMA, and CGI-S scores were significantly reduced with both RAS and RDS. RAS patients had numerically greater reductions in HAMD-17 scores than RDS patients (8.9 +/- 7.4 vs. 6.2 +/- 6.2, effect size [ES]=0.40), while RDS patients had greater improvement in HAMA scores (8.2 +/- 8.0 vs. 5.3 +/- 5.8, ES=0.42). RAS was associated with clinically relevant advantages in response (54.5% vs. 18.2%, number-needed-to-treat [NNT]=3) and remission (36.4% vs. 9.1%, NNT=4). BDNF increased significantly during the 6-week study period (p<0.05), with greater increases in RAS at weeks 4 and 6 (ES=0.66-0.76) and statistical superiority at week 2 (p=0.034, ES=1.23). Baseline BDNF in the 8 responders (24.8+/-9.0 ng/ml) was lower than in the 14 nonresponders (31.1+/-7.3 ng/ml, p=0.083, ES=-0.79), and BDNF increased more in responders (8.9+/-7.8 ng/ml) than in nonresponders (1.8+/ 3.5 ng/ml, p=0.044). The change in BDNF at week 2 was the most strongly predicted response (p=0.016). CONCLUSIONS: Rhythmic LFMS was effective for MDD. BDNF may moderate/mediate the efficacy of LFMS. PMID- 29460713 TI - Assessing the Ability of Hospital Diagnosis Codes to Detect Inpatient Exposure to Antibacterial Agents. AB - OBJECTIVE Because antibacterial history is difficult to obtain, especially when the exposure occurred at an outside hospital, we assessed whether infection related diagnostic billing codes, which are more readily available through hospital discharge databases, could infer prior antibacterial receipt. DESIGN Retrospective cohort study. PARTICIPANTS This study included 121,916 hospitalizations representing 78,094 patients across the 3 hospitals. METHODS We obtained hospital inpatient data from 3 Chicago-area hospitals. Encounters were categorized as "infection" if at least 1 International Classification of Disease, Ninth Revision, Clinical Modification (ICD-9-CM) code indicated a bacterial infection. From medication administration records, we categorized antibacterial agents and calculated total therapy days using Centers for Disease Control and Prevention (CDC) definitions. We evaluated bivariate associations between infection encounters and 3 categories of antibacterial exposure: any, broad spectrum, or surgical prophylaxis. We constructed multivariable models to evaluate adjusted risk ratios for antibacterial receipt. RESULTS Of the 121,916 inpatient encounters (78,094 patients) across the 3 hospitals, 24% had an associated infection code, 47% received an antibacterial, and 13% received a broad-spectrum antibacterial. Infection-related ICD-9-CM codes were associated with a 2-fold increase in antibacterial administration compared to those lacking such codes (RR, 2.29; 95% confidence interval [CI], 2.27-2.31) and a 5-fold increased risk for broad-spectrum antibacterial administration (RR, 5.52; 95% CI, 5.37-5.67). Encounters with infection codes had 3 times the number of antibacterial days. CONCLUSIONS Infection diagnostic billing codes are strong surrogate markers for prior antibacterial exposure, especially to broad-spectrum antibacterial agents; such an association can be used to enhance early identification of patients at risk of multidrug-resistant organism (MDRO) carriage at the time of admission.

PMID- 29460714 TI - Seroprevalence of Dengue Antibodies in Three Urban Settings in Yucatan, Mexico. AB - Dengue transmission in Mexico has become a major public health problem. Few epidemiological studies have examined the seroprevalence of dengue in Mexico, and recent estimates are needed to better understand dengue transmission dynamics. We conducted a dengue seroprevalence survey among 1,668 individuals including all age groups in three urban settings in Yucatan, Mexico. Children (< 19 years old) were selected randomly from schools. The adults (>= 19 years old) were selected from healthcare facilities. Participants were asked to provide a venous blood sample and to answer a brief questionnaire with demographic information. Previous exposure to dengue was determined using indirect immunoglobulin G enzyme-linked immunosorbent assay. The overall seroprevalence was 73.6%. The age-specific seroprevalence increased with age, going from 51.4% (95% confidence interval [CI] = 45.0-57.9%) in children <= 8 years to 72% (95% CI = 66.3-77.2%) in the 9- to 14 years old. The highest seroprevalence was 83.4% (95% CI = 77-82.2%) in adults greater than 50 years. The seroprevalence in Merida was 68.6% (95% CI = 65-72%), in Progreso 68.7% (95% CI = 64.2-72.8%), and in Ticul 85.3% (95% CI = 81.9 88.3%). Ticul had the highest seroprevalence in all age groups. Logistic regression analysis showed that age and city of residence were associated with greater risk of prior dengue exposure. The results highlight the level of past exposure to dengue virus including young children. Similar studies should be conducted elsewhere in Mexico and other endemic countries to better understand the transmission dynamics of dengue. PMID- 29460716 TI - Role of Wild-type and Recombinant Human T-cell Leukemia Viruses in Lymphoproliferative Disease in Humanized NSG Mice. AB - Chronic infection with human T-cell leukemia virus type 1 (HTLV1) can lead to adult T-cell leukemia (ATL). In contrast, infection with HTLV2 does not lead to leukemia, potentially because of distinct virus-host interactions and an active immune response that controls virus replication and, therefore, leukemia development. We created a humanized mouse model by injecting human umbilical-cord stem cells into the livers of immunodeficient neonatal NSG mice, resulting in the development of human lymphocytes that cannot mount an adaptive immune response. We used these mice to compare the ability of molecular clones of HTLV1, HTLV2, and select recombinant viruses to induce leukemia-lymphoma in vivo. Infection with HTLV1 strongly stimulated the proliferation of CD4+ T cells, whereas HTLV2 preferentially stimulated the proliferation of CD8+ T cells; both HTLV1 and HTLV2 induced lymphoproliferative disease. Uninfected and HTLV-infected humanized mice both showed granulomatous inflammation as a background lesion. Similarly, recombinant viruses that expressed the HTLV1 envelope protein (Env) on an HTLV2 background (HTLV2-Env1) or Env2 on an HTLV1 background (HTLV1-Env2) induced lymphoproliferative disease. HTLV2-Env1 stimulated the proliferation of CD4+ T cells, whereas HTLV1-Env2 stimulated both CD4+ and CD8+ T-cell subsets. Our results show that T-cell transformation in vivo is guided by the Env protein of the virus. Furthermore, our humanized mouse model is useful for exploring the preferred T-cell tropisms of HTLV1 and HTLV2. PMID- 29460717 TI - Strain-specific Differences in the Effects of Lymphocytes on the Development of Insulin Resistance and Obesity in Mice. AB - Obesity is characterized as a chronic, low-grade inflammatory disease owing to the infiltration of the adipose tissue by macrophages. Although the role of macrophages in this process is well established, the role of lymphocytes in the development of obesity and metabolism remains less well defined. In the current study, we fed WT and Rag1-/- male mice, of C57BL/6J and BALB/c backgrounds, high fat diet (HFD) or normal diet for 15 wk. Compared with WT mice, Rag1-/- mice of either of the examined strains were found less prone to insulin resistance after HFD, had higher metabolic rates, and used lipids more efficiently, as shown by the increased expression of genes related to fatty acid oxidation in epidydimal white adipose tissue. Furthermore, Rag1-/- mice had increased Ucp1 protein expression and associated phenotypic characteristics indicative of beige adipose tissue in subcutaneous white adipose tissue and increased Ucp1 expression in brown adipose tissue. As with inflammatory and other physiologic responses previously reported, the responses of mice to HFD show strain-specific differences, with increased susceptibility of C57BL/6J as compared with BALB/c strain. Our findings unmask a crucial role for lymphocytes in the development of obesity and insulin resistance, in that lymphocytes inhibit efficient dissipation of energy by adipose tissue. These strain-associated differences highlight important metabolic factors that should be accommodated in disease modeling and drug testing. PMID- 29460718 TI - Cutaneous Dermatophilosis in a Meadow Jumping Mouse (Zapus hudsonius). AB - A laboratory-housed, wild-caught, subadult, male meadow jumping mouse (Zapus hudsonius) presented with extensive scaling of the face, limbs, and tail and severe edema of the paws. Postmortem examination revealed marked distal limb edema with focal digital hematomas and white scales, scabs, and crusts affecting the majority of nonhaired skin. Histopathologic analysis revealed severe, multifocal, chronic-active exudative and proliferative dermatitis characterized by multilaminated crusts covering the epidermis. The epidermis was expanded by hyperkeratosis, acanthosis, and hyperplasia. The superficial dermis contained moderate edema, hemorrhage, and pigmentary incontinence, and was infiltrated by granulocytes and mononuclear cells. The laminated crusts contained numerous branching filaments of gram-positive coccoid bodies arranged in parallel rows, consistent with cutaneous Dermatophilus congolensis infection. This diagnosis was confirmed through bacterial culture and 16S rRNA PCR analysis. In the presented case, factors that might have contributed to disease progression include climatic conditions at the capture site and stress associated with trapping and laboratory housing. PMID- 29460719 TI - Characterization of Cotton Rat (Sigmodon hispidus) Eosinophils, Including Their Response to Respiratory Syncytial Virus Infection. AB - Eosinophils have been postulated to play a protective role against infection with respiratory syncytial virus (RSV), increase the severity of allergic asthma during respiratory viral infection, and drive vaccine-enhanced disease. To address these questions in the cotton rat model of RSV infection, we characterized cotton rat eosinophils by electron microscopy as well as by bronchoalveolar lavage and histology of lung sections. Using these methods, we demonstrated that eosinophils comprise approximately half of all cells in the bronchoalveolar lavage fluids from cotton rats. The function of these cells was comparable to that of eosinophils of other species. Ex vivo, eosinophils stimulated with calcium ionophores secreted eosinophil peroxidase. In vivo, treatment with house dust mite antigen increased eosinophil numbers in lung. Infection with Staphylococcus aureus lead to a marked increase in neutrophils without an increase in eosinophils, and eosinophil numbers were not influenced by infection with influenza virus or measles virus. Similarly, infection with RSV did not result in an increase in eosinophils. Lastly, RSV infection did not increase eosinophil recruitment into the lung after challenge with house dust mite antigen, but it did increase eosinophil recruitment into the lungs of cotton rats previously immunized with formalin-inactivated RSV vaccine, thus contributing to vaccine-enhanced disease. PMID- 29460720 TI - Humane Endpoints for Guinea Pigs Used for Mycobacterium tuberculosis Vaccine Research. AB - Guinea pigs are a commonly used model for tuberculosis vaccine research. Loss of body weight is the most frequently described humane endpoint for animals used in these studies. During a chronic study, we noted labored breathing in some tuberculosis-infected guinea pigs. To develop consistent humane endpoints for these guinea pigs, we performed an observational study using multiple clinical signs. A combination of body weight loss, labored breathing, and activity level during handling estimated the time to euthanasia within approximately 7 d. Histologic severity scores of lesions in the cranial or caudal lung lobe (or both) supported clinical endpoints. This study presents humane endpoints for the refinement of studies using guinea pigs in tuberculosis research. PMID- 29460721 TI - Duodenal Cannulation in Pigs (Sus scrofa) as a Drug Delivery Method. AB - Currently available animal models for delivery of drug capsules and pharmacokinetic testing are limited by either intersubject variability in gastric emptying time or the need to sedate animals when using targeted delivery methods of drug capsules. With the increasing development of large-molecule biologics, better in vivo models for testing the pharmacokinetics of capsule-delivered drugs are urgently needed. To this end, we made engineering modifications to an existing bovine surgical cannula device, successfully implanted this modified cannula into pigs, and delivered drug capsules directly to the proximal duodenum. In our porcine model, capsule insertion and serial blood samples were all acquired without the use of sedatives. Furthermore, we were able to maintain cannulated pigs for weekly pharmacokinetic testing for more than 18 mo, with minimal postoperative complications. This study demonstrates a novel and effective porcine model of sedation-free drug delivery and blood collection that eliminates inconsistencies associated with models that require either gastric emptying or animal sedation. PMID- 29460722 TI - Cutaneous Toxicity in a Laboratory Beagle (Canis lupus familiaris) after Chronic Administration of Doxorubicin Hydrochloride. AB - An adult female beagle (Canis lupus familiaris) used in a model of doxorubicin induced cardiomyopathy presented with epithelial desquamation on the shoulders and ventrum after receiving the 8th weekly intravenous dose of the free form of doxorubicin (20 mg/m2; total accumulation, 160 mg/m2). The lesions were empirically treated with topical disinfectants and topical and systemic antibiotics. Despite treatment, the lesions progressed and ulcerated. Bacterial culture revealed Staphylococcus aureus, but trichogram, skin scraping, and fungal culture were negative for microorganisms. Skin biopsies revealed epidermal and apocrine gland hyperplasia, apocrine gland dilation, abnormal maturation of epithelial keratinocytes, and perivascular lymphocytic infiltration. These histopathologic findings resemble those in humans and canines after chronic administration of doxorubicin-containing pegylated liposomes. Here we report a clinical presentation after chronic administration of the free form of doxorubicin. In dogs, cutaneous toxicity after administration of pegylated liposomal doxorubicin is most often localized to the footpads, limbs, and axillary and urogenital regions. In the current case, lesions affected the ventrum and trunk but did not involve the footpads or axillary or urogenital regions. PMID- 29460723 TI - Model of Traumatic Spinal Cord Injury for Evaluating Pharmacologic Treatments in Cynomolgus Macaques (Macaca fasicularis). AB - Here we present the results of experiments involving cynomolgus macaques, in which a model of traumatic spinal cord injury (TSCI) was created by using a balloon catheter inserted into the epidural space. Prior to the creation of the lesion, we inserted an EMG recording device to facilitate measurement of tail movement and muscle activity before and after TSCI. This model is unique in that the impairment is limited to the tail: the subjects do not experience limb weakness, bladder impairment, or bowel dysfunction. In addition, 4 of the 6 subjects received a combination treatment comprising thyrotropin releasing hormone, selenium, and vitamin E after induction of experimental TSCI. The subjects tolerated the implantation of the recording device and did not experience adverse effects due the medications administered. The EMG data were transformed into a metric of volitional tail moment, which appeared to be valid measure of initial impairment and subsequent natural or treatment-related recovery. The histopathologic assessment demonstrated widespread axon loss at the site of injury and areas cephalad and caudad. Histopathology revealed evidence of continuing inflammation, with macrophage activation. The EMG data did not demonstrate evidence of a statistically significant treatment effect.

AB - A 13-y-old, multiparous female black-crested mangabey (Lophocebus aterrimus) underwent surgical treatment for chronically recurring rectal prolapse by laparotomy and subsequent colopexy. Initially, a laparoscopic approach was attempted but was converted to an open approach after intraabdominal adhesions were noted. The colopexy was performed through a ventral midline incision, with no complications intraoperatively or postoperatively. The predisposing factors responsible for the development of this condition likely were related to pelvic floor weakness due to multiple past pregnancies. Transport-associated stressors likely contributed to the acute worsening of this patient's condition. Rectal prolapse is a common condition in laboratory-housed NHP. This case report describes an effective surgical treatment for recurring or otherwise nonreducible rectal prolapse in these species. PMID- 29460727 TI - A Comparative Analysis of Economic Cost of Podoconiosis and Leprosy on Affected Households in the Northwest Region of Cameroon. AB - Leprosy and podoconiosis (podo) are neglected tropical diseases that cause severe disfigurement and disability, and may lead to catastrophic health expenditure and hinder economic development of affected persons and households. This study compared economic costs of both diseases on affected households with unaffected neighboring households in the Northwest Region (N.W.R.) of Cameroon. A matched comparative cross-sectional design was used enrolling 170 households (43 podo case households, 41 podo control households, 43 leprosy case households, and 43 leprosy control households) from three health districts in the N.W.R. Direct treatment costs for podo averaged 142 United State dollar (USD), compared with zero for leprosy (P < 0.001). This was also reflected in the proportion of annual household income consumed (0.4 versus 0.0, respectively, P < 0.001). Both diseases caused considerable reductions in working days (leprosy 115 versus podo 135 days. P for comparison < 0.001). The average household income was considerably lower in podo-affected households than unaffected households (410 versus 913 USD, P = 0.01), whereas income of leprosy-affected households was comparable to unaffected households (329 versus 399 USD, P = 0.23). Both leprosy and podo cause financial burdens on affected households, but those on podo affected families are much greater. These burdens occur through direct treatment costs and reduced ability to work. Improved access to public health interventions for podo including prevention, morbidity management and disability prevention are likely to result in economic returns to affected families. In Cameroon, one approach to this would be through subsidized health insurance for these economically vulnerable households. PMID- 29460729 TI - Use of Genome Sequencing to Define Institutional Influenza Outbreaks, Toronto, Ontario, Canada, 2014-15. AB - Adequacy of the current clinical definition of institutional influenza outbreaks is unclear. We performed a retrospective genome sequencing and epidemiologic analysis of institutional influenza outbreaks that occurred during the 2014-15 influenza season in Toronto, Canada. We sequenced the 2 earliest submitted samples positive for influenza A(H3N2) from each of 38 reported institutional outbreaks in long-term care facilities. Genome sequencing showed most outbreak pairs identified by using the current clinical definition were highly related. Inclusion of surveillance samples demonstrated that outbreak sources were likely introductions from broader circulating lineages. Pairwise distance analysis using majority genome and hemagglutinin-specific genes enabled identification of thresholds for discrimination of within and between outbreak pairs; the area under the curve ranged 0.93-0.95. Routine genome sequencing for defining influenza outbreaks in long-term care facilities is unlikely to add significantly to the current clinical definition. Sequencing may prove most useful for investigating sources of outbreak introductions.

AB - Encapsulated Haemophilus influenzae strains belong to type-specific genetic lineages. Reliable capsule typing requires PCR, but a more efficient method would be useful. We evaluated capsule typing by using matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry. Isolates of all capsule types (a-f and nontypeable; n = 258) and isogenic capsule transformants (types a-d) were investigated. Principal component and biomarker analyses of mass spectra showed clustering, and mass peaks correlated with capsule type-specific genetic lineages. We used 31 selected isolates to construct a capsule typing database. Validation with the remaining isolates (n = 227) showed 100% sensitivity and 92.2% specificity for encapsulated strains (a-f; n = 61). Blinded validation of a supplemented database (n = 50) using clinical isolates (n = 126) showed 100% sensitivity and 100% specificity for encapsulated strains (b, e, and f; n = 28). MALDI-TOF mass spectrometry is an accurate method for capsule typing of H. influenzae.

We showed that 80.8% (21/26) of patients at Ghindae Hospital and 41.7% (10/24) at Massawa Hospital were infected with pfhrp2-negative parasites and 92.3% (24/26) of patients at Ghindae Hospital and 70.8% (17/24) at Massawa Hospital were infected with pfhrp3-negative parasites. Parasite densities between pfhrp2 positive and pfhrp2-negative patients were comparable. All pfhrp2-negative samples had no detectable HRP2/3 antigen and showed negative results for HRP2 based RDTs. pfhrp2-negative parasites were genetically less diverse and formed 2 clusters with no close relationships to parasites from Peru. These parasites probably emerged independently by selection in Eritrea. High prevalence of pfhrp2 negative parasites caused a high rate of false-negative results for RDTs. Determining prevalence of pfhrp2-negative parasites is urgently needed in neighboring countries to assist case management policies. PMID- 29460731 TI - Multistate Epidemiology of Histoplasmosis, United States, 2011-2014 AB - Histoplasmosis is one of the most common mycoses endemic to the United States, but it was reportable in only 10 states during 2016, when a national case definition was approved. To better characterize the epidemiologic features of histoplasmosis, we analyzed deidentified surveillance data for 2011-2014 from the following 12 states: Alabama, Arkansas, Delaware, Illinois, Indiana, Kentucky, Michigan, Minnesota, Mississippi, Nebraska, Pennsylvania, and Wisconsin. We examined epidemiologic and laboratory features and calculated state-specific annual and county-specific mean annual incidence rates. A total of 3,409 cases were reported. Median patient age was 49 (interquartile range 33-61) years, 2,079 (61%) patients were male, 1,273 (57%) patients were hospitalized, and 76 (7%) patients died. Incidence rates varied markedly between and within states. The high hospitalization rate suggests that histoplasmosis surveillance underestimates the true number of cases. Improved surveillance standardization and surveillance by additional states would provide more comprehensive knowledge of histoplasmosis in the United States. PMID- 29460732 TI - Emergence of Streptococcus pneumoniae Serotype 12F after Sequential Introduction of 7- and 13-Valent Vaccines, Israel. AB - Israel implemented use of 7- and 13-valent pneumococcal vaccine in 2009 and 2010, respectively. We describe results of prospective, population-based, nationwide active surveillance of Streptococcus pneumoniae serotype 12F (Sp12F) invasive pneumococcal disease (IPD) dynamics in the 7 years after vaccine introduction. Of 4,573 IPD episodes during July 2009-June 2016, a total of 434 (9.5%) were caused by Sp12F. Sp12F IPD rates (cases/100,000 population) increased in children <5 years of age, from 1.44 in 2009-2010 to >3.9 since 2011-2012, followed by an increase in all ages. During 2011-2016, Sp12F was the most prevalent IPD serotype. Sp12F isolates were mostly penicillin nonsusceptible (MIC >0.06 ug/mL; MIC50 = 0.12) and predominantly of sequence type 3774), a clone exclusively found in Israel (constituting ~90% of isolates in 2000-2009). The sharp increase, long duration, and predominance of Sp12F IPD after vaccine implementation reflect a single clone expansion and may represent more than a transient outbreak. PMID- 29460733 TI - Influenza Vaccination and Incident Tuberculosis among Elderly Persons, Taiwan1. AB - Experimental studies have demonstrated that influenza vaccination may protect against tuberculosis (TB) through a Th17 response. This nationwide cohort study aimed to evaluate the association of influenza vaccination with incident TB among elderly persons in Taiwan. This 2005-2012 study included 99,982 elderly persons (64,290 vaccinated and 35,692 unvaccinated) from the Taiwan National Health Insurance Research Database. During the 738,367 person-years of follow-up, 1,141 (1.14%) persons had incident TB. The cumulative incidences of TB were 145.2 cases/100,000 person-years among vaccinated elderly persons and 175.5 cases/100,000 person-years among unvaccinated elderly persons (p = 0.002). The time-dependent Cox proportional hazards model revealed that influenza vaccination was an independent protective factor for incident TB. Our results suggest that influenza vaccination is associated with a lower risk of incident TB among elderly persons in Taiwan. Further investigation of biologic mechanisms is warranted. PMID- 29460734 TI - Increasing Prevalence of Nontuberculous Mycobacteria in Respiratory Specimens from US-Affiliated Pacific Island Jurisdictions1. AB - Nontuberculous mycobacteria (NTM) respiratory infections represent a growing public health problem in many countries. However, there are limited published epidemiologic studies for the Western Pacific region. We reviewed respiratory specimens submitted to Diagnostic Laboratory Services in Hawaii, USA, for culture of Mycobacterium tuberculosis during August 2007-December 2011 to determine the NTM isolation rate. We observed a statistically significant increase in the rate of specimens with NTM isolated in respiratory culture (adjusted rate ratio per year 1.65, 95% CI 1.54-1.77; p<0.01). In contrast, the number of patients with respiratory cultures positive for M. tuberculosis showed no increase (adjusted rate ratio per year 0.98, 95% CI 0.94-1.01; p = 0.19). A 6-month subset of NTM isolates was identified by using a nucleic acid probe or 16S rRNA sequencing. M. avium complex and M. fortuitum were the most common NTM identified. PMID- 29460735 TI - Acquired Resistance to Antituberculosis Drugs in England, Wales, and Northern Ireland, 2000-2015. AB - Among tuberculosis (TB) patients, acquired resistance to anti-TB drugs represents a failure in the treatment pathway. To improve diagnosis and care for patients with drug-resistant TB, we examined the epidemiology and risk factors associated with acquired drug resistance during 2000-2015 among TB patients in England, Wales, and Northern Ireland. We found acquired resistance in 0.2% (158/67,710) of patients with culture-confirmed TB. Using multivariate logistic regression, we identified the following factors associated with acquired drug resistance: having pulmonary disease; initial resistance to isoniazid, rifampin, or both; a previous TB episode; and being born in China or South Africa. Treatment outcomes were worse for patients with than without acquired resistance. Although acquired resistance is rare in the study area, certain patient groups are at higher risk. Identifying these patients and ensuring that adequate resources are available for treatment may prevent acquisition of resistance, thereby limiting transmission of drug-resistant strains of mycobacteria. PMID- 29460737 TI - Use of Verbal Autopsy to Determine Underlying Cause of Death during Treatment of Multidrug-Resistant Tuberculosis, India. AB - Of patients with multidrug-resistant tuberculosis (MDR TB), <50% complete treatment. Most treatment failures for patients with MDR TB are due to death during TB treatment. We sought to determine the proportion of deaths during MDR TB treatment attributable to TB itself. We used a structured verbal autopsy tool to interview family members of patients who died during MDR TB treatment in India during January-December 2016. A committee triangulated information from verbal autopsy, death certificate, or other medical records available with the family members to ascertain the underlying cause of death. For 66% of patient deaths (47/71), TB was the underlying cause of death. We assigned TB as the underlying cause of death for an additional 6 patients who died of suicide and 2 of pulmonary embolism. Deaths during TB treatment signify program failure; accurately determining the cause of death is the first step to designing appropriate, timely interventions to prevent premature deaths. PMID- 29460736 TI - Epidemiology and Molecular Identification and Characterization of Mycoplasma pneumoniae, South Africa, 2012-2015. AB - During 2012-2015, we tested respiratory specimens from patients with severe respiratory illness (SRI), patients with influenza-like illness (ILI), and controls in South Africa by real-time PCR for Mycoplasma pneumoniae, followed by culture and molecular characterization of positive samples. M. pneumoniae prevalence was 1.6% among SRI patients, 0.7% among ILI patients, and 0.2% among controls (p<0.001). Age <5 years (adjusted odd ratio 7.1; 95% CI 1.7-28.7) and HIV infection (adjusted odds ratio 23.8; 95% CI 4.1-138.2) among M. pneumonia positive persons were associated with severe disease. The detection rate attributable to illness was 93.9% (95% CI 74.4%-98.5%) in SRI patients and 80.7% (95% CI 16.7%-95.6%) in ILI patients. The hospitalization rate was 28 cases/100,000 population. We observed the macrolide-susceptible M. pneumoniae genotype in all cases and found P1 types 1, 2, and a type 2 variant with multilocus variable number tandem repeat types 3/6/6/2, 3/5/6/2, and 4/5/7/2. PMID- 29460739 TI - Use of Influenza Risk Assessment Tool for Prepandemic Preparedness. AB - In 2010, the Centers for Disease Control and Prevention began to develop an Influenza Risk Assessment Tool (IRAT) to methodically capture and assess information relating to influenza A viruses not currently circulating among humans. The IRAT uses a multiattribute, additive model to generate a summary risk score for each virus. Although the IRAT is not intended to predict the next pandemic influenza A virus, it has provided input into prepandemic preparedness decisions. PMID- 29460738 TI - Prospective Observational Study of Incidence and Preventable Burden of Childhood Tuberculosis, Kenya. PMID- 29460740 TI - Ending the HIV/AIDS Pandemic1. AB - The goal of ending the HIV/AIDS pandemic is theoretically achievable and would require addressing this global health catastrophe on individual and global levels by providing optimal prevention strategies and treatment regimens for individual persons living with or at risk for HIV, as well as ending the pandemic as an epidemiologic and global health phenomenon. However, from a practical standpoint, the pathway to ending the HIV/AIDS pandemic will be difficult and will require aggressive implementation of the biomedical research advances that have been made in the areas of treatment and prevention; development of additional tools, such as a moderately effective HIV vaccine; and attention to critical behavioral and social determinants. An end to the HIV/AIDS pandemic can be achieved only with provision of sustained and additional resources at the local, regional, national, and global levels. PMID- 29460741 TI - Coccidioidomycosis Outbreaks, United States and Worldwide, 1940-2015. AB - Coccidioidomycosis causes substantial illness and death in the United States each year. Although most cases are sporadic, outbreaks provide insight into the clinical and environmental features of coccidioidomycosis, high-risk activities, and the geographic range of Coccidioides fungi. We identified reports published in English of 47 coccidioidomycosis outbreaks worldwide that resulted in 1,464 cases during 1940-2015. Most (85%) outbreaks were associated with environmental exposures; the 2 largest outbreaks resulted from an earthquake and a large dust storm. More than one third of outbreaks occurred in areas where the fungus was not previously known to be endemic, and more than half of outbreaks involved occupational exposures. Coccidioidomycosis outbreaks can be difficult to detect and challenging to prevent given the unknown effectiveness of environmental control methods and personal protective equipment; therefore, increased awareness of coccidioidomycosis outbreaks is needed among public health professionals, healthcare providers, and the public. PMID- 29460742 TI - Invasive Infections Caused by Nannizziopsis spp. Molds in Immunocompromised Patients. AB - We report 2 new cases of invasive infections caused by Nannizziopsis spp. molds in France. Both patients had cerebral abscesses and were immunocompromised. Both patients had recently spent time in Africa. PMID- 29460743 TI - Genetic Spatiotemporal Anatomy of Plasmodium vivax Malaria Episodes in Greece, 2009-2013. AB - An influx of immigrants is contributing to the reemergence of Plasmodium vivax malaria in Greece; 1 persistent focus of transmission is in Laconia, Peloponnese. We genotyped archived blood samples from a substantial proportion of malaria cases recorded in Greece in 2009-2013 using 8 microsatellite markers and a PvMSP 3alpha gene fragment and plotted their spatiotemporal distribution. High parasite genetic diversity with low multiplicity of infection was observed. A subset of genetically identical/related parasites was restricted to 3 areas in migrants and Greek residents, with some persisting over 2 consecutive transmission periods. We identified 2 hitherto unsuspected additional foci of local transmission: Kardhitsa and Attica. Furthermore, this analysis indicates that several cases in migrants initially classified as imported malaria were actually locally acquired. This study shows the potential for P. vivax to reestablish transmission and counsels public health authorities about the need for vigilance to achieve or maintain sustainable malaria elimination. PMID- 29460744 TI - Increase in Hospital Admissions for Severe Influenza A/B among Travelers on Cruise Ships to Alaska, 2015. AB - An increase in hospital admissions for influenza occurred during the summer of 2015 at an acute care facility in Vancouver, British Columbia, Canada. Investigation identified 25 patients with recent history of cruise ship travel to Alaska. All characterized influenza A viruses were A(H3N2). We describe patient treatment regimens and outcomes. PMID- 29460745 TI - Seroprevalence of Dengue and Chikungunya Virus Antibodies, French Polynesia, 2014 2015. AB - We investigated dengue and chikungunya virus antibody seroprevalence in French Polynesia during 2014-2015. Dengue virus seroprevalence was ~60% among schoolchildren and >83% among the general population; chikungunya virus seroprevalence was <3% before and 76% after Zika virus emergence (2013). Dengue virus herd immunity may affect Zika virus infection and pathogenesis. PMID- 29460746 TI - Global Health Estimate of Invasive Mycobacterium chimaera Infections Associated with Heater-Cooler Devices in Cardiac Surgery. AB - Investigations of a worldwide epidemic of invasive Mycobacterium chimaera associated with heater-cooler devices in cardiac surgery have been hampered by low clinical awareness and challenging diagnoses. Using data from Switzerland, we estimated the burden of invasive M. chimaera to be 156-282 cases/year in 10 major cardiac valve replacement market countries. PMID- 29460747 TI - Epidemiology of Recurrent Hand, Foot and Mouth Disease, China, 2008-2015. AB - Using China's national surveillance data on hand, foot and mouth disease (HFMD) for 2008-2015, we described the epidemiologic and virologic features of recurrent HFMD. A total of 398,010 patients had HFMD recurrence; 1,767 patients had 1,814 cases of recurrent laboratory-confirmed HFMD: 99 reinfections of enterovirus A71 (EV-A71) with EV-A71, 45 of coxsackievirus A16 (CV-A16) with CV-A16, 364 of other enteroviruses with other enteroviruses, 383 of EV-A71 with CV-A16 and CV-A16 with EV-A71, and 923 of EV-A71 or CV-A16 with other enteroviruses and other enteroviruses with EV-A71 or CV-A16. The probability of HFMD recurrence was 1.9% at 12 months, 3.3% at 24 months, 3.9% at 36 months, and 4.0% at 38.8 months after the primary episode. HFMD severity was not associated with recurrent episodes or time interval between episodes. Elucidation of the mechanism underlying HFMD recurrence with the same enterovirus serotype and confirmation that HFMD recurrence is not associated with disease severity is needed. PMID- 29460748 TI - Drug Resistance of Mycobacterium tuberculosis Complex in a Rural Setting, Angola. AB - We found high prevalence rates of multidrug-resistant tuberculosis among retreatment patients (71.1%) and persons with new cases (8.0%) in Angola. These findings are of concern but should be interpreted with caution. A national drug resistance survey is urgently needed to determine the actual prevalence of multidrug-resistant tuberculosis in Angola. PMID- 29460749 TI - Statistical Method to Detect Tuberculosis Outbreaks among Endemic Clusters in a Low-Incidence Setting. AB - We previously reported use of genotype surveillance data to predict outbreaks among incident tuberculosis clusters. We propose a method to detect possible outbreaks among endemic tuberculosis clusters. We detected 15 possible outbreaks, of which 10 had epidemiologic data or whole-genome sequencing results. Eight outbreaks were corroborated. PMID- 29460750 TI - Whole-Genome Analysis of Mycobacterium tuberculosis from Patients with Tuberculous Spondylitis, Russia. AB - Whole-genome analysis of Mycobacterium tuberculosis isolates collected in Russia (N = 71) from patients with tuberculous spondylitis supports a detailed characterization of pathogen strain distributions and drug resistance phenotype, plus distinguished occurrence and association of known resistance mutations. We identify known and novel genome determinants related to bacterial virulence, pathogenicity, and drug resistance. PMID- 29460751 TI - Mycobacterium avium subsp. hominissuis Infection in a Domestic Rabbit, Germany. AB - Mycobacterium avium subsp. hominissuis is an opportunistic pathogen present in soil and dust.

This introduction underscores the risk for local malaria transmission and the vulnerability of New Caledonia to vector introduction. PMID- 29460753 TI - Fishborne Zoonotic Trematodes Transmitted by Melanoides tuberculata Snails, Peru. AB - We investigated the transmission of the fishborne trematodes Centrocestus formosanus and Haplorchis pumilio by Melanoides tuberculata snails in Peru. We report on results of experimental, morphological, and molecular approaches and discuss the potential risk for future human cases, given the existence of food habits in the country involving the ingestion of raw fish. PMID- 29460754 TI - Delftia tsuruhatensis, an Emergent Opportunistic Healthcare-Associated Pathogen. AB - Delftia tsuruhatensis, which was first isolated in environmental samples, was rarely associated with human infections. We report on pneumonia caused by D. tsuruhatensis in an infant who underwent cardiac surgery. Retrospective analyses detected 9 other isolates from 8 patients. D. tsuruhatensis is an emergent pathogen, at least for immunocompromised patients. PMID- 29460755 TI - Severe Pneumonia Caused by Toxigenic Corynebacterium ulcerans Infection, Japan. AB - Corynebacterium ulcerans infection was recently recognized as a zoonosis. We present 2 cases of severe pneumonia complicated by diffuse pseudomembrane formation on the bronchus caused by C. ulcerans-producing diphtheria toxin. Our purpose is to alert medical professionals to the virulence of Corynebacterium species other than C. diphtheriae. PMID- 29460756 TI - Characteristics Associated with Negative Interferon-gamma Release Assay Results in Culture-Confirmed Tuberculosis Patients, Texas, USA, 2013-2015. AB - Interferon-gamma release assays (IGRAs) are the preferred diagnostic test for tuberculosis (TB) infection in at-risk populations in developed countries. However, IGRAs have high false-negative rates in patients with TB disease. Population-based studies assessing the factors associated with negative IGRA results in TB patients have not been performed. Using statewide TB surveillance data of culture-confirmed TB patients in Texas, USA, during 2013-2015, we describe the patient characteristics and treatment outcomes associated with false negative IGRA results. Among 2,854 TB patients, 1,527 (53.5%) had an IGRA result; 97.4% (1,487/1,527) of those had a positive (87.7%) or negative (12.3%) result. Older age, HIV co-infection, non-Hispanic white race/ethnicity, and being tested with T-SPOT.TB were associated with negative IGRA results. TB patients with negative IGRA results had a higher mortality, potentially due to delayed treatment. Healthcare providers should consider these risk factors when making decisions for patients with suspected TB and negative IGRA results and potentially provide treatment. PMID- 29460757 TI - Acetobacter indonesiensis Pneumonia after Lung Transplantation. AB - We report a case of Acetobacter indonesiensis pneumonia in a 51-year-old woman after bilateral lung transplantation. We found 2 other A. indonesiensis pneumonia cases reported in the literature. All 3 cases involved complex patients exposed to broad-spectrum antimicrobial drugs, suggesting that this pathogen may be opportunistic and highly drug-resistant. PMID- 29460758 TI - New Lineage of Lassa Virus, Togo, 2016. AB - We describe a strain of Lassa virus representing a putative new lineage that was isolated from a cluster of human infections with an epidemiologic link to Togo. This finding extends the known range of Lassa virus to Togo. PMID- 29460759 TI - Molecular and Epidemiologic Analysis of Reemergent Salmonella enterica Serovar Napoli, Italy, 2011-2015. AB - Human infections with Salmonella enterica serovar Napoli are uncommon in Europe. However, these infections represented 5.9% of salmonellosis cases in Italy during 2014-2015. The source of infection is unknown. We analyzed surveillance data and compared strain genetic similarities and found that contaminated vegetables and surface water are probable sources of human infection. PMID- 29460760 TI - Artificial Differences in Clostridium difficile Infection Rates Associated with Disparity in Testing. AB - In 2015, Clostridium difficile testing rates among 30 US community, multispecialty, and cancer hospitals were 14.0, 16.3, and 33.9/1,000 patient days, respectively. Pooled hospital onset rates were 0.56, 0.84, and 1.57/1,000 patient-days, respectively. Higher testing rates may artificially inflate reported rates of C. difficile infection. C. difficile surveillance should consider testing frequency. PMID- 29460761 TI - Evidence for Previously Unidentified Sexual Transmission of Protozoan Parasites. AB - Knowing the mode of transmission of a disease can affect its control and prevention. Here, we identify 5 protozoan parasites with demonstrated presence in seminal fluid, only 1 of which has been identified as a sexually transmitted disease among humans. PMID- 29460763 TI - Roles of Graphic Pathographies in Clinical Training. AB - Although graphic pathographies have recently been recognized as playing an important role in medical care, they have not been formally incorporated in many medical school curricula. In this paper, I discuss current applications of graphic pathographies in medicine as well as some potential ethical and epistemological challenges that can arise when using these narratives. Health professionals and medical educators should understand when, why, and how to use graphic pathographies with the goal of enhancing medical education and patient care. PMID- 29460762 TI - Cache Valley Virus in Aedes japonicus japonicus Mosquitoes, Appalachian Region, United States. AB - We detected Cache Valley virus in Aedes japonicus, a widely distributed invasive mosquito species, in an Appalachian forest in the United States. The forest contained abundant white-tailed deer, a major host of the mosquito and virus. Vector competence trials indicated that Ae. j. japonicus mosquitoes can transmit this virus in this region. PMID- 29460764 TI - Representations of Patients' Experiences of Autonomy in Graphic Medicine. AB - I advocate using graphic medicine in introductory medical ethics courses to help trainees learn about patients' experiences of autonomy. Graphic narratives about this content offer trainees opportunities to gain insights into making diagnoses and recommending treatments. Graphic medicine can also illuminate aspects of patients' experiences of autonomy differently than other genres. Specifically, comics allow readers to consider visual and text-based representations of a patient's actions, speech, thoughts, and emotions. Here, I use Ellen Forney's Marbles: Mania, Depression, Michelangelo, and Me: A Graphic Memoir and Peter Dunlap-Shohl's My Degeneration: A Journey Through Parkinson's as two examples that can serve as pedagogical resources. PMID- 29460765 TI - Are Comic Books Appropriate Health Education Formats to Offer Adult Patients? AB - Physicians who recommend patient education comics should consider that some patients might question the appropriateness of this format, especially in the US, where a dominant cultural view of comics is that they are juvenile and intended to be funny. In this case, Dr. S might have approached communication with Mrs. T differently, even without knowing her attitude toward comics as a format for delivering health information. Dr. S could acknowledge that though some people might not expect useful medical information in a comic format, it has unique aspects and new research on patient education comics shows that even adults are finding this medium to be effective, educational, and engaging. Offering comics to patients, however, does potentially require patient educators to invest additional time to review and assess their accuracy and relevance. PMID- 29460766 TI - Go Home, Med Student: Comics as Visual Media for Students' Traumatic Medical Education Experiences. AB - A comic created by a medical student allows the reader to share the student's own unique perception of the medical education experience. Through the process of comic creation, medical students have opportunities to gain insight into how their relationships with patients and supervising physicians have shaped the physician they will become. The comic itself can be a safe space for expression and provides an opportunity for students and educators to share experiences. PMID- 29460767 TI - How Should a Stigmatized Diagnosis Be Conveyed? How What Went Wrong Is Represented in Swallow Me Whole. AB - This essay considers the ethical problems raised by a scene of diagnosis presentation in Nate Powell's graphic novel Swallow Me Whole, in which the patient is not only not engaged by the physician, but also effectively marginalized from the moment that her condition is named and medicalized. Put in the context of the book as a whole and in relationship to the unique affordances of the comics form, however, we see that though the physician made a correct diagnosis, the case did not end well due to the poor delivery of that diagnosis and the lack of support from members of the patient's extended community. PMID- 29460768 TI - Teaching Confidentiality through Comics at One Spanish Medical School. AB - At the University of Zaragoza in Spain we developed an innovative way to teach the concept of confidentiality to medical students, which we tested by comparing the use of customized comics with more traditional methods. We proved that using comics is more attractive to students than lectures and class discussions, that it increases class participation and students' self-awareness of learning, and that it maintains the same academic results. We share our experience visually in a two-page comic. PMID- 29460769 TI - Graphic Pathographies and the Ethical Practice of Person-Centered Medicine. AB - Graphic medicine is a swiftly growing movement that explores, theoretically and practically, the use of comics in medical education and patient care. At the heart of graphic medicine are graphic pathographies, stories of illness conveyed in comic form. These stories are helpful tools for health care professionals who seek new insight into the personal, lived experience of illness and for patients who want to learn more about their disease from others who have actually experienced it. Featuring excerpts from five graphic pathographies, this essay illustrates how the medium can be used to educate patients and enhance empathy in health care professionals, particularly with regard to informed consent and end of-life issues. PMID- 29460770 TI - Parasites! Graphic Exploration of Tropical Disease Drug Development. AB - Parasites!, a 2010 comic sponsored by the Wellcome Trust Centre for Molecular Parasitology, demonstrates that a graphic narrative can play a role in energizing public debate. Part of the genre known as graphic medicine-comics about illness, treatment, disability, and caregiving-Parasites! is intended to educate readers of all ages about illnesses less known in the developed world. Two visual strategies in particular enable the comic to offer an alternative and aesthetic response to questions about developing drugs to treat tropical diseases for profit. By including visuals and text, and not just one of these formats, viewers must reorient themselves aesthetically and epistemologically to ethical, social, cultural, and political structures that adversely affect human health. PMID- 29460771 TI - How Should We Judge the Ethics of Illustrations in Graphic Medicine Novels? AB - This essay argues that we should judge the illustrations in a graphic novel (often a memoir) in the context of the entire work. Judging a work on its emotive effects and the values it expresses, we can consider the ways a graphic novel represents the experience of illness, disability, or injury. PMID- 29460772 TI - Of Cornopleezeepi and Party Poopers: A Brief History of Physicians in Comics. AB - The representations of physicians and medical practice found in comic strips, comic books, and graphic novels throughout the past century reflect broader representational trends in popular visual media. Drawing on examples including Winsor McCay's Dream of the Rarebit Fiend, the superhero comics character Stephen Strange/Doctor Strange, and contemporary graphic medicine, this article outlines the shifting models for depicting physicians and medical ethics in comics. It concludes that contemporary representations are often more realistic and nuanced, although gender and racial diversity along with diversity in medical specializations remains problematic. PMID- 29460773 TI - The Crisis in Our Neighborhood. AB - This comic represents various clinical and ethical dimensions of the skyrocketing incidence of opioid overdose. The comic also seeks to represent the humanity of patients struggling with addiction and to highlight the importance of clinicians' roles in helping mitigate the harms of opioid dependence. PMID- 29460774 TI - Reviewing Systems. AB - This poster represents the experience of a clinician-in-training with a diagnostic screening method typically called "review of systems." Although at times executing this method can feel onerous, it is intended to reveal key symptoms, promote inquiry, and enhance communication. It also sometimes generates unexpected and important insights, and that experience is conveyed here with a combination of text and images. PMID- 29460775 TI - Representing AIDS in Comics. AB - Matthew P. McAllister wrote: "Comic books can and have contributed positively to the discourse about AIDS: images that encourage true education, understanding and compassion can help cope with a biomedical condition which has more than a biomedical relevance" [1]. With this in mind, I combined a 23-narrator oral history and my personal memoir about an inpatient Chicago AIDS hospital unit in my book, Taking Turns: Stories from HIV/AIDS Care Unit 371. In doing so, I built upon the existing rich history of HIV/AIDS in comics, which this article will briefly describe. Although not a comprehensive review of the intersection of AIDS and comics, the book is a tour through influences that proved useful to me. In addition, in making my book, I faced a distinct ethical issue with regard to representing patient experiences with HIV/AIDS, and I describe here how I addressed it. PMID- 29460776 TI - Preserving neuromuscular synapses in ALS by stimulating MuSK with a therapeutic agonist antibody. AB - In amyotrophic lateral sclerosis (ALS) and animal models of ALS, including SOD1 G93A mice, disassembly of the neuromuscular synapse precedes motor neuron loss and is sufficient to cause a decline in motor function that culminates in lethal respiratory paralysis. We treated SOD1-G93A mice with an agonist antibody to MuSK, a receptor tyrosine kinase essential for maintaining neuromuscular synapses, to determine whether increasing muscle retrograde signaling would slow nerve terminal detachment from muscle. The agonist antibody, delivered after disease onset, slowed muscle denervation, promoting motor neuron survival, improving motor system output, and extending the lifespan of SOD1-G93A mice. These findings suggest a novel therapeutic strategy for ALS, using an antibody format with clinical precedence, which targets a pathway essential for maintaining attachment of nerve terminals to muscle. PMID- 29460777 TI - Confirmation for conformational selection. AB - NMR studies settle part of a long-standing debate about the mechanism used by the Hsp70 chaperone to recognize substrates. PMID- 29460778 TI - Conserved conformational selection mechanism of Hsp70 chaperone-substrate interactions. AB - Molecular recognition is integral to biological function and frequently involves preferred binding of a molecule to one of several exchanging ligand conformations in solution. In such a process the bound structure can be selected from the ensemble of interconverting ligands a priori (conformational selection, CS) or may form once the ligand is bound (induced fit, IF). Here we focus on the ubiquitous and conserved Hsp70 chaperone which oversees the integrity of the cellular proteome through its ATP-dependent interaction with client proteins. We directly quantify the flux along CS and IF pathways using solution NMR spectroscopy that exploits a methyl TROSY effect and selective isotope-labeling methodologies. Our measurements establish that both bacterial and human Hsp70 chaperones interact with clients by selecting the unfolded state from a pre existing array of interconverting structures, suggesting a conserved mode of client recognition among Hsp70s and highlighting the importance of molecular dynamics in this recognition event.

AB - Recent work has estimated that sub-Saharan Africa could lose US$3.5 billion of economic productivity every year as a result of schistosomiasis and soil transmitted helminthiasis. One of the main interventions to control schistosomiasis is the provision of safe water to limit the contact with infected water bodies and break the cycle of transmission. To date, a rigorous quantification of the impact of safe water supplies on schistosomiasis is lacking. Using data from one of Africa's largest population-based cohorts, we establish the impact of the scale-up of piped water in a typical rural South African population over a seven-year time horizon. High coverage of piped water in the community decreased a child's risk of urogenital schistosomiasis infection eight-fold (adjusted odds ratio = 0.12, 95% CI 0.06-0.26, p<0.001). The provision of safe water could drive levels of urogenital schistosomiasis infection to low levels of endemicity in rural African settings. PMID- 29460781 TI - The burden and nature of malnutrition among patients in regional hospital settings: A cross-sectional survey. AB - BACKGROUND/AIMS: Indigenous people experience a higher burden of nutrition related conditions and are more likely to experience food insecurity compared to non-Indigenous people. Consequently, they remain at increased risk of malnutrition; particularly when residing in regional or remote areas. This study aims to compare and characterise the burden and nature of malnutrition among a representative cohort of Indigenous and non-Indigenous Australians admitted to regional hospitals for medical inpatient care. METHODS: This was a cross sectional survey conducted in three regional hospitals in the Northern Territory and Far North Queensland of Australia from February 2015 to September 2015. A total of 1606 adult medical inpatients were screened for eligibility. Of these, 608 eligible patients were screened for malnutrition using the validated Malnutrition Screening Tool and assessed for malnutrition using the Subjective Global Assessment. Socio-economic and health-related variables and anthropometric measurements were collected to identify the correlates of malnutrition. RESULTS: Of the 271 Indigenous patients and 337 non-Indigenous patients screened and assessed for malnutrition, 250/608 (41.7%, 95% CI 40.1-52.3%) were found to be malnourished. Significantly higher rates of malnutrition (46.1%, 95% CI 40.1 52.3% versus 37.1%, 95% CI 31.9-42.5%) were found in Indigenous patients compared to non-Indigenous patients (P = 0.024). Higher rates of malnutrition were observed in Indigenous patients residing in Central Australia (56.7%, 95% CI 46.7 66.4%) than in the Top End of the Northern Territory (40.7%, 95% CI 31.7-50.1%) and in Far North Queensland (36.7%, 95% CI 23.4-51.7%). Factors independently predictive of malnutrition for both Indigenous and non-Indigenous participants included residence in Central Australia (OR 4.31, 95% CI 2.63-7.90, P < 0.001); an increased Charlson Comorbidity Index prognostic score (OR 1.37 [per incremental score], 95% CI 1.19-1.59, P < 0.001); and an underweight Body Mass Index (OR 29.97, 95% CI 3.68-244.0, P < 0.001). Of the 250/608 patients who were malnourished, the positive predictor value (PPV) for malnourished patients who were underweight was 96.6% (95% CI 88.3-99.6%); for Indigenous Australians who were malnourished and underweight, the PPV was 100%. A mid-upper arm circumference of less than 23 cm demonstrated a strong PPV for all patients who were malnourished (96.1%, 95% CI 89.0-99.2%). CONCLUSION: This is the first study to characterise malnutrition in adult Indigenous Australians in a hospital inpatient setting. Compared to non-Indigenous patients the burden and pattern of malnutrition was both higher and markedly different among Indigenous patients. These data highlight the critical importance for actively screening for and responding to malnutrition in this vulnerable patient population in regional and remote settings.

AB - Ribonucleotide reductases (RNRs) convert ribonucleotides into deoxyribonucleotides, a reaction essential for DNA replication and repair. Human RNR requires two subunits for activity, the alpha subunit contains the active site, and the beta subunit houses the radical cofactor. Here, we present a 3.3-A resolution structure by cryo-electron microscopy (EM) of a dATP-inhibited state of human RNR. This structure, which was determined in the presence of substrate CDP and allosteric regulators ATP and dATP, has three alpha2 units arranged in an alpha6 ring. At near-atomic resolution, these data provide insight into the molecular basis for CDP recognition by allosteric specificity effectors dATP/ATP. Additionally, we present lower-resolution EM structures of human alpha6 in the presence of both the anticancer drug clofarabine triphosphate and beta2. Together, these structures support a model for RNR inhibition in which beta2 is excluded from binding in a radical transfer competent position when alpha exists as a stable hexamer. PMID- 29460782 TI - Dietary acid load and risk of type 2 diabetes: A systematic review and dose response meta-analysis of prospective observational studies. AB - BACKGROUND & AIMS: Existing evidence suggests a link between acid-forming potential of diet and type 2 diabetes. But the degree of the associations and shape of the dose-response relations across different indices of diet-dependent acid load and risk of type 2 diabetes and potential confounding by sex have not been established. We aimed to test the dose-response association of different measures of dietary acid load and risk of incident type 2 diabetes, with considering the sex as a potential confounder. METHODS: Systematic search was done using PubMed and Scopus, from inception up to September 2017. Prospective observational studies reporting the risk estimates of type 2 diabetes for three or more quantitative categories of potential renal acid load (PRAL), net endogenous acid production (NEAP) and animal protein-to-potassium ratio (A:P) scores were included. Pooled relative risks (RRs) were calculated using random effects models. RESULTS: Seven prospective cohort studies with 319,542 participants and 17,986 incident cases of type 2 diabetes were included. Pooled RRs for a 5 unit increment in dietary PRAL, NEAP and A:P was 1.04 (95% CI: 1.01, 1.06; I2 = 79%, n = 7), 1.03 (95% CI: 1.01, 1.04; I2 = 54%, n = 7), and 1.11 (95% CI: 1.07, 1.15; I2 = 41%, n = 3), respectively. Subgroup analysis resulted in significant positive relationship only among women, compared with men. There was a linear association between NEAP and A:P scores and risk of type 2 diabetes, whereas the association appeared to be U-shaped in analysis of PRAL. CONCLUSIONS: Adherence to a diet with high acid-forming potential might increase the risk of type 2 diabetes. Shape of the dose-response relations across different indices of dietary acid load and potential sex differences in the associations need to be further explored. The interpretation of the results is limited by low number of studies. PMID- 29460783 TI - Zusto: A new sweetening agent with low glycemic index. AB - BACKGROUND & AIMS: Sweetening agents are sugar substitutes with a low glycemic index, used to obtain a better glycemic control in diabetes patients. However, they also may have a role in other subjects, as a high glycemic index is thought to cause many pathological conditions. Unfortunately, not all artificial sweeteners are perceived as sweet as sugar by patients. Consumers refer often to an after taste present in foods sweetened with intensive sweeteners. The objective of this study was to explore whether Zusto(r) had a low glycemic index, to replace glucose as a sweetener. METHODS: In this study, the glycemic index (GI) of a new sweetening agent, Zusto(r), is compared to that of glucose 25 g, a standard sugar-loaded drink used in the oral glucose tolerance test to detect diabetes, as primary endpoint. Zusto(r) is composed of non-digestible, water soluble fibers and sweeteners. 10 healthy, female non-obese volunteers received glucose and Zusto(r), albeit by an interval of a week. Evolution of glycemia, C peptide and insulin release was measured at different time-points after intake. RESULTS: The results show that, when calculating the mean incremental Area Under the Curve (AUC), the AUC of glucose was around five times as high as that of Zusto(r); a GI of 22 for Zusto(r) was calculated. Furthermore, Zusto(r) had no significant effect on the glycemia, contrary to glucose, for at least 60'. This was also the case concerning C-peptide and insulin release, but the difference lasted even for 180'. Moreover, Zusto(r) was perceived as sweet by all volunteers, with no particular aftertaste. CONCLUSION: Zusto(r) could be a viable alternative for fast sugars and other sweetening agents, both for diabetic patients and other subjects, requiring however a larger trial to confirm these results.

AB - BACKGROUND: Skin cancers are the most prevalent malignancy worldwide and Basal Cell Carcinoma (BCC) include the major type of nonmelanoma skin cancers. Fatty acids (FA) have a structural role in cell membranes and play an important role for many physiological and pathological immunologic pathways. Several prospective studies have been conducted on circulating fatty acids and the risk of prostate, breast and other cancers. The present study aimed to determine the saturated fatty acid composition differences of red blood cells (RBCs) in BCC patients and healthy control. METHODS: A hospital-based case-control study was conducted on new cases diagnosed of BCC patients. All subjects completed dietary recalls for dietary assessment. After fatty acids extraction, purification and preparation, gas chromatography was performed. The results were expressed in relative values (percent). RESULTS: Cases had lower RBC levels of Caproic acid (6:0) (P < 0.001), Caprylic acid (8:0) (P = 0.01), Capric acid (10:0) (P = 0.01), Palmitic acid (16:0) (P = 0.02) and higher RBC level of Pentadecanoic acid (15:0) (P = 0.04) and Stearic acid (18:0) (P = 0.01) compared with controls but did not differ in the level of the other primary saturated fatty acids. Saturation Index as defined by Stearic to Oleic acid ratio was significantly lower in BCC patients in comparison with Control group (P = 0.02). CONCLUSION: Here we showed that BCC patient had considerable differences in the SFA profiles in comparison with healthy subjects. PMID- 29460785 TI - The association between nutritional status and frailty characteristics among geriatric outpatients. AB - BACKGROUND: Frailty is a common clinical syndrome in older adults and is associated with an increased risk of poor health outcomes, e.g. falls, disability, hospitalization, and mortality. Nutritional status might be an important factor contributing to frailty. This study aims to describe the association between nutritional status and characteristics of frailty in patients attending a geriatric outpatient clinic. METHODS: Clinical data was collected of 475 patients who visited the geriatric outpatient department of a Dutch hospital between 2005 and 2010. Frailty was determined by: incontinence, Activities of Daily Living (ADL), Instrumental Activities of Daily Living (IADL), mobility, Geriatric Depression Scale (GDS) and Mini Mental State Exam (MMSE). Nutritional status was represented by the Mini Nutritional Assessment (MNA) and plasma concentrations of several micronutrients, whereby MNA< 17 indicated malnutrition and MNA 17-23.5 indicated risk of malnutrition. 'More frail' patients (>=3 frailty characteristics) were compared to 'less frail' patients (<3 frailty characteristics) with logistic regression analyses, adjusted for age, sex and other important covariates. RESULTS: Of 404 patients with complete data, mean age (SD) was 80 (7) years and 34% was male. Prevalence of 'more frail' patients was 47%. Prevalence of malnutrition and risk of malnutrition was 16% and 56% respectively. Malnutrition and risk of malnutrition were both independently related to being 'more frail', with ORs (95% CI) of 8.1 [3.5-18.8] and 3.1 [1.7 5.5] respectively. This association was driven by functional decline (ADL, IADL and mobility) and depression (GDS), but not by cognitive impairment (MMSE). None of the micronutrient plasma concentrations were related to frailty. CONCLUSION: In geriatric outpatients, malnutrition is independently related to having >=3 frailty characteristics. Assessing nutritional status could prove usefulness in early clinical detection and prevention of frailty. PMID- 29460786 TI - Appropriateness of peripheral parenteral nutrition use in adult patients at an academic medical center. AB - BACKGROUND & AIMS: Current evidence and guidelines identify patient populations who may benefit from parenteral nutrition. Peripheral parenteral nutrition (PPN) may be indicated for a subset of patients; however, PPN therapy carries a risk of associated adverse effects. The purpose of this project was to assess appropriateness of current PPN prescribing practices at an academic medical center to determine whether additional guidance and oversight may be beneficial. METHODS: Adult patients admitted from August 1, 2015 to November 30, 2015 with at least one order of PPN administered were included. PPN use was evaluated for appropriateness using definitions derived from clinical practice guidelines and standard of practice. Adverse events, including phlebitis and bacteremia, were also examined. RESULTS: Of the 159 patients included, 51 (32.1%) received appropriate PPN therapy, in which all four criteria for appropriateness were met. In regards to the criteria for appropriateness, 128 (80.5%) had an appropriate indication, 85 (53.5%) had appropriate time to PPN initiation, 157 (98.7%) had an appropriate duration of therapy, and 112 (70.4%) achieved an appropriate percentage of goal daily calories. In terms of complications associated with PPN therapy, 69 (43.4%) patients had documented phlebitis and bacteremia occurred in 5 (3.1%) of the patients. CONCLUSION: During the study period, PPN was appropriately utilized in only one-third of patients and phlebitis occurred in almost half of all patients. Restrictions on PPN prescribing may allow nutrition support clinicians to prospectively evaluate patients to optimize nutrition therapy and minimize the incidence of inappropriate PPN use. PMID- 29460787 TI - Accuracy of the visual estimation method as a predictor of food intake in Alzheimer's patients provided with different types of food. AB - BACKGROUND & AIMS: The visual estimation method is commonly used in hospitals and other care facilities to evaluate food intake through estimation of plate waste. In Japan, no previous studies have investigated the validity and reliability of this method under the routine conditions of a hospital setting. The present study aimed to evaluate the validity and reliability of the visual estimation method, in long-term inpatients with different levels of eating disability caused by Alzheimer's disease. The patients were provided different therapeutic diets presented in various food types. METHODS: This study was performed between February and April 2013, and 82 patients with Alzheimer's disease were included. Plate waste was evaluated for the 3 main daily meals, for a total of 21 days, 7 consecutive days during each of the 3 months, originating a total of 4851 meals, from which 3984 were included. Plate waste was measured by the nurses through the visual estimation method, and by the hospital's registered dietitians through the actual measurement method. The actual measurement method was first validated to serve as a reference, and the level of agreement between both methods was then determined. The month, time of day, type of food provided, and patients' physical characteristics were considered for analysis. RESULTS: For the 3984 meals included in the analysis, the level of agreement between the measurement methods was 78.4%. Disagreement of measurements consisted of 3.8% of underestimation and 17.8% of overestimation. Cronbach's alpha (0.60, P < 0.001) indicated that the reliability of the visual estimation method was within the acceptable range. CONCLUSION: The visual estimation method was found to be a valid and reliable method for estimating food intake in patients with different levels of eating impairment. The successful implementation and use of the method depends upon adequate training and motivation of the nurses and care staff involved. PMID- 29460788 TI - Metabolic syndrome among rural Indian adults. AB - BACKGROUND & AIMS: To prevent an increasing level of mortality due to type 2 diabetes mellitus and cardiovascular disease among the rural Indian population, a management strategy of the metabolic syndrome (MetS) should be devised. This study aims to estimate the burden of MetS and its associated risk factors. METHODS: Data from the Birbhum Population Project covering 9886 individuals (4810 male and 5076 female population) aged >=18 years were used. The burden of metabolic syndrome, as defined by the Third Report of the National Cholesterol Education Program Adult Treatment Panel, was determined. Bivariate and multivariate (logistic regression) analyses were used to attain the study objective. RESULTS: Over 10.7% of the males and 20.3% of the females were diagnosed with MetS. Irrespective of sex, older individuals, being overweight/obese (body mass index of >=23 kg/m2) had higher probability of developing MetS, whereas being underweight is deemed a protective factor against MetS. Low physical activity among women appeared to be a risk factor for MetS. CONCLUSION: The prevalence of MetS is concerning even in rural India. Any intervention designed to address the issue could emphasize on weight loss, and physical activity, focusing on women and people at an advanced stage of life. PMID- 29460789 TI - Percutaneous endoscopic gastrostomy (PEG) versus radiologically inserted gastrostomy (RIG): A comparison of outcomes at an Australian teaching hospital. AB - OBJECTIVE: Gastrostomy tubes for enteral nutrition are most commonly inserted via percutaneous endoscopic gastrostomy (PEG) or radiologically inserted gastrostomy (RIG) techniques. The current study aimed to compare clinical outcomes and complication rates in patients who underwent PEG and RIG procedures at a tertiary teaching hospital in Australia. METHODS: A retrospective review was conducted on patients who underwent PEG or RIG tube insertion between February 2013 and February 2015 at Flinders Medical Centre, Australia. The primary outcome studied was the tube dislodgement rate. Secondary outcomes measured included hospital length of stay, 30 day and 1 year mortality and peri- and post-procedural complications such as hypoxia, bleeding, stoma site infection and haematoma. Baseline comparisons were conducted using the Mann-Whitney test and chi square test. RESULTS: 137 patients (PEG = 85, RIG = 52) underwent gastrostomy tube insertion. Indications for insertion were head and neck cancer (PEG = 30, RIG = 21), stroke (PEG = 27, RIG = 11), post-trauma (PEG = 6, RIG = 3) and neuromuscular pathologies (PEG = 9, RIG = 0). There was a significantly higher tube dislodgement rate in RIG (26.5%) compared to PEG (2.4%), p < 0.001. The 1 year mortality was also significantly higher after RIG (46.2%) compared to the PEG group (16.7%), p < 0.05. No differences were seen in other peri- and post procedural complications. CONCLUSION: Although both PEG and RIG insertion techniques compare favourably in terms of the majority of peri and post procedural complications, the rates of tube dislodgement were significantly higher in the RIG group. The higher mortality rate at 1 year after RIG placement may be related to patient selection particularly as no differences were seen at 30 days. PMID- 29460790 TI - Protein and micronutrient deficiencies in patients with radiation cystitis and outcome after hyperbaric oxygen therapy. AB - BACKGROUND & AIMS: Haemorrhagic radiation cystitis (HRC) is a late complication of pelvic radiotherapy. Severe cases are difficult to treat due to persistent or recurrent bleeding, despite urological and hyperbaric oxygen therapy (HBOT). However, wound healing requires a good nutritional status. In this respect, we aimed at analysing the nutritional status of patients with HRC prior to the onset of HBOT and at highlighting predictive nutritional factors of outcome. METHODS: Data were retrospectively collected from a cohort of 179 patients with HRC (between 2011 and 2015). Haematuria was graded according to the Subjective, Objective, Management, Analytic scale (SOMA): grade-4 (n = 46) was compared with grade-3 (n = 56), and with grades 1 and 2 (n = 77). S-albumin, prealbumin, vitamins C, D and B6, zinc, selenium, and essential fatty acids were evaluated before HBOT. HBOT response was measured at 3 months according to the haematuria SOMA grade. The Mann-Whitney test, Fisher's exact test and principal-component analysis were used to compare groups. RESULTS: Patients with higher haematuria grades (3 and 4) harboured significant deficiencies in S-albumin, prealbumin, vitamins C, D and B6, zinc, selenium and essential fatty acids. Moreover, grade-4 patients without improvement after 3 months of HBOT had significant lower initial levels of S-albumin, vitamin C, selenium and linoleic acid. Vitamin C levels <2.5 mg/L were strongly associated with HBOT non-response (OR 23.14, 95% CI 3.73 143.69, p = 0.002). CONCLUSIONS: Our analyses show serious nutritional deficiencies associated with higher grades of HRC and worse prognoses. Patients with haemorrhagic cystitis might benefit from an adequate dietary supplementation to support healing of their bladder mucosa. PMID- 29460791 TI - Hypercholesterolemia and hypertriglyceridemia as risk factors of liver dysfunction in children with inflammation receiving total parenteral nutrition. AB - BACKGROUND AND AIMS: Hepatic dysfunction, due to parenteral nutrition, may become severe and lead to cirrhosis and hepatic failure, especially in newborns and infants. This study aimed to evaluate the association between the exclusive use of total parenteral nutrition (TPN) and changes in the hepatic profile, and to investigate the relationship between age, hypertriglyceridemia, and hypercholesterolemia, and the occurrence of laboratory liver dysfunction. METHODS: A descriptive and historical cohort study was conducted, evaluating 195 pediatric patients (age: 1 month to 19 years) who received TPN. The following hepatic and lipid profiles were assessed: alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase, gamma-glutamyl transferase (GGT), bilirubin, triglycerides (TGs), cholesterol, high-density lipoprotein (HDL), albumin, and transthyretin. High C-reactive protein and/or low HDL were considered indicative of inflammatory process. RESULTS: The majority of patients presented normal values of AST (79.2%), ALT (74.9%), GGT (56.4%), and alkaline phosphatase (68.1%). Total bilirubin changed in 68.5% of patients, and transthyretin and albumin were low in 87.3% and 65.1% of the patients, respectively. Incidences of high GGT values were related to age (odds ratio [OR], 2.46; confidence interval [CI] 1.28-4.76; p = 0.007), hypercholesterolemia (OR, 3.00; 95% CI, 1.24-7.25; p = 0.015), and hypertriglyceridemia (OR, 2.39; 95% CI, 1.02-5.60; p = 0.046). Incidences of elevated ALT values were associated with hypercholesterolemia (OR, 4.57; 95% CI, 2.03-10.30; p < 0.001). CONCLUSION: Monitoring the hepatic profile from the early stage of TPN is necessary. Changes in the plasma lipid and hepatic profiles were frequently observed during the infusion of TPN, in patients with inflammation. Patients >2 years old and those with high TG and HDL levels were more likely to have elevated GGT levels. Hypercholesterolemia was associated with ALT alterations. Strategies to attenuate these issues should be considered in the early stages, in patients with TPN. PMID- 29460792 TI - Comparing assessment tools for detecting undernutrition in patients with liver cirrhosis. AB - BACKGROUND AND AIMS: Undernutrition in cirrhotic patients is often poorly recognised until late-stages. The current UK screening tool, the Malnutrition Universal Screening Tool, can miss undernutrition in patients with ascites/fluid retention. A 6-question Liver Disease Undernutrition Screening Tool (LDUST) has been developed in America. METHODS: We sought to compare LDUST with MUST in the detection of undernutrition in 50 inpatients and 50 outpatients with liver cirrhosis in a secondary care setting. This was then validated by a dietitian assessment. RESULTS: Similar patient demographics and liver disease aetiologies were found in the two cohorts. Mean Child-Pugh scores were higher for inpatients, 8.3 (SD 1.9) vs 5.9 (SD 1.2). LDUST detected undernutrition in 45/50 inpatients (90%) and 34/50 outpatients (68%). MUST scores >=2 were present in 19/50 (38%) inpatients and 9/50 (18%) outpatients. In those with a MUST score <2, LDUST detected undernutrition in 26/31 (84%) inpatients and 27/41 (66%) outpatients. 26 inpatients had undernutrition using LDUST but had a MUST score <2, 20 (76%) of these were deemed to be undernourished by dietetics assessment. LDUST was mostly completed independently or with minimal assistance (80% inpatients, 100% outpatients), with mean completion times of 4 and 3 min for in- and outpatients respectively. CONCLUSION: LDUST is a quick and easy screening tool, which appears better able than MUST to detect undernutrition in cirrhotic patients, including undernutrition missed by MUST. Importantly the tool was validated against dietitian assessments. The high rates of undernutrition among cirrhotic inpatients suggest that screening this cohort is unnecessary, and instead all should undergo dietitian review, with LDUST utilised in an outpatient setting. PMID- 29460793 TI - A prospective study of energy and protein intakes in critically ill patients. AB - BACKGROUND & AIMS: Providing adequate and appropriate food and nutrients satisfying the patients' safe nutritional need is one of the most important care practices for critically ill patients (CIPs) in ICU settings, and is strongly related to the patients' safety. METHODS: In this prospective cross-sectional study data were collected from a 52-bed medical intensive care unit on 777 consecutive patients in six different ICUs. The patients' weights and heights were measured based on ulna length, knee height, MAC, Calf C, and Wrist C. Also, patient weight change history was asked for. All currently in-use dietary supplements and formulas in the ICU settings were checked for their ingredients. The patients' nutritional need was calculated individually for the disease state based on dietary ESPEN guidelines. RESULTS: Mean ICU and hospital stay duration was 14.45 +/- 11.81 and 15.38 +/- 11.88 days respectively. Mean energy and protein requirements in the target population were 1804.61 +/- 201.76 Kcal/day and 77.94 +/- 12.72 gr/day, respectively. Mean actual energy and protein intakes were 1052.75 +/- 561.25 Kcal/day and 35.38 +/- 23.19 gr/day, respectively. Satisfaction percents for mean energy and protein requirement in the total population were 58.34% (1052.75/1804.4) and 45.41% (35.38/77.9), respectively. In 21.4% and 4.4% of the studied group, energy and protein intakes were about 75 100% of the patients' actual need, respectively. Another data analysis for patients with over 10 days of inpatient time showed that only 14.2% of patients had energy intakes, and only 3.2% of them had protein intakes in the range of 75 100% of their requirements. CONCLUSION: Results showed that energy and protein intakes in CIPs are low, disproportionate to their requirements. Therefore, actual dietary intake records, individual dietary requirement calculation, and individual dietary planning in relation with the patients' disease and stress should be considered. Such an accurate nutritional care process can promote patient safety. PMID- 29460794 TI - Definitions of hunger and fullness among youth enrolled in a pediatric weight management program. AB - The development and maintenance of obesity is multifactorial and involves the interplay of environmental, cultural, social, and biological influences. The purpose of the current paper was to describe hunger and fullness in a sample of pediatric patients seeking treatment for obesity. The goals of this study were to gain information about how youth with obesity describe their experience of being hungry and full and to explore common themes within these descriptions. Twenty five patients entering a Stage 3 pediatric obesity program responded to the open ended questions: "how do you know when you are hungry" and "how do you know when you are full?" The results found that the majority of youth used physical cues as a way to identify hunger and fullness cues. For identifying hunger, participants most frequently reported using cues such as their stomach growling or stomach pain as an indication that they are hungry. For identifying fullness, the majority of participants relied on discomfort. The current findings suggest that youth with obesity are able to attend to extreme physical cues (e.g., pain, sickness) of fullness but may not be aware of subtle cues that allow them to stop eating once they are satisfied. PMID- 29460795 TI - Evidence the U.S. autism epidemic initiated by acetaminophen (Tylenol) is aggravated by oral antibiotic amoxicillin/clavulanate (Augmentin) and now exponentially by herbicide glyphosate (Roundup). AB - Because certain hereditary diseases show autistic behavior, and autism often runs in families, researchers seek genes underlying the pathophysiology of autism, thus core behaviors. Other researchers argue environmental factors are decisive, citing compelling evidence of an autism epidemic in the United States beginning about 1980. Recognition that environmental factors influence gene expression led to synthesis of these views - an 'epigenetic epidemic' provoked by pervasive environmental agents altering expression of vulnerable genes, inducing characteristic autistic biochemistries in many mothers and infants. Two toxins most implicated in the U.S. autism epidemic are analgesic/antipyretic acetaminophen (Tylenol) and oral antibiotic amoxicillin/clavulanate (Augmentin). Recently herbicide glyphosate (Roundup) was exponentially implicated. What do these toxins have in common? Acetaminophen depletes sulfate and glutathione required to detoxify it. Oral antibiotics kill and glyphosate inhibits intestinal bacteria that synthesize methionine (precursor of sulfate and glutathione, and required to methylate DNA), bacteria that synthesize tryptophan (sole precursor of neuroinhibitor serotonin), and bacteria that restrain ammonia-generating anaerobes. Sulfate plus glutathione normally sulfate fetal adrenal androgen dehydroepiandrosterone to DHEAS - major precursor of placental/postnatal estrogens. Glyphosate (and heavy metals) also inhibit aromatase that turns androgens to estrogens. Placental/postnatal estrogens dehydrate/mature brain myelin sheaths, mature corpus callosum and left hemisphere preferentially, dilate brain blood vessels, and elevate brain serotonin and oxytocin. Stress-induced weak androgens and estrogen depletion coherently explain white matter asymmetry and dysconnection in autism, extreme male brain, low brain blood flow, hyperexcitability, social anxiety, and insufficient maternal oxytocin at birth to limit fetal brain chloride/water and mature GABA. PMID- 29460796 TI - Effects of goal-directed fluid therapy on enhanced postoperative recovery: An interventional comparative observational study with a historical control group on oesophagectomy combined with ERAS program. AB - BACKGROUND AND AIMS: The Enhanced Recovery after Surgery (ERAS) program has been proposed as a postoperative recovery-enhancing strategy. We frequently apply the Modified-ERAS program following oesophagectomy. This study aims to elucidate the impact of goal-directed fluid therapy (GDT) for the perioperative management of oesophageal cancer on the postoperative recovery of patients undergoing oesophagectomy. METHODS: This is an interventional before-after comparative observational study conducted at Kanagawa Cancer Centre, Japan. Patients who underwent elective oesophagectomy for oesophageal cancer were recruited. Group H (retrospectively collected) received intraoperative and postoperative management consisting of fluid administration without haemodynamic monitoring and the M-ERAS program, while Group S prospectively received management consisting of GDT and the M-ERAS program. The primary endpoint was the speed of gastrointestinal functional recovery, while secondary endpoints were the level of postoperative mobilisation, incidence of complications, postoperative length of hospital stay (LOS), and nutritional status after discharge. RESULTS: The proportion of patients who completely egested Gastrografin by postoperative day 4, the level of postoperative mobilisation, and achievement ratio for a 100-m walk on the first postoperative attempt were significantly higher in Group S than in Group H (P = 0.034, P = 0.0197, and P < 0.0001, respectively). No significant differences were observed in the postoperative LOS and incidence of complications within 30 days between the groups. The serum albumin levels at 6 months after discharge was higher in Group S than in Group H (P = 0.0002). CONCLUSIONS: The GDT-ERAS program enhanced postoperative gastrointestinal recovery and mobilisation, as well as postoperative nutritional status and protein synthesis. The program did not affect either postoperative LOS or the incidence of complications.

PMID- 29460797 TI - Insights of hypercarotenaemia: A brief review. AB - Carotenoids are generally 40-carbon tetraterpenoids responsible for most of the yellow, orange and red colours throughout the natural world. Pro-vitamin A carotenoids serve as the precursors of vitamin A. In addition to that, carotenoids exhibit range of important protective mechanisms in human health. Hypercarotenaemia is characterized by carotenodermia resulting in yellowing of the skin specially palms and soles. Hypercarotenaemia develops in subjects consuming high levels of carotenoid rich foods or beta-carotene supplements (>30 mg day-1) over a period of months. Less or normal intake of carotenoids very rarely gives rise to metabolic carotenaemia due to genetic defects of the enzyme 15-15'-carotenoid dioxygenase. Moreover, it is known that those with hypothyroidism and diabetes mellitus tend to develop hypercarotenaemia with the normal intake of carotenoid rich foods. Further, hypercarotenaemia has been reported in anorexia nervosa. However, recently some studies have been shown that there is no major correlation between carotenoid intake and hypercarotenaemia indicating that a genetic factor is at play in development of hypercarotenaemia. Therefore, the subjects appear to need to be genetically pre-disposed to hypercarotenaemia. PMID- 29460798 TI - Major liver resection reduces nonprotein respiratory quotient and increases nonesterified fatty acid at postoperative day 14 in patients with hepatocellular carcinoma. AB - BACKGROUND & AIMS: We reported decreased nonprotein respiratory quotient (npRQ) after liver resection in patients with hepatocellular carcinoma (HCC); however, whether liver resection volume affects energy metabolism in these patients is unclear. We aimed to examine the relationship between liver resection and energy metabolism indices. METHODS: NpRQ was measured in 53 patients with HCC and seven with at the pre- and postoperative days. Patients were classified into four groups: Minor-lowICG group (n = 17): minor (subsegment or less) resection and low indocyanine green retention rate at 15 min (ICGR15) (<15%); Minor-highICG group (n = 18): minor resection and high ICGR15 (>=15%) and Major-lowICG group (n = 18): major (lobe) resection and low ICGR15 (<15%). We investigated dietary intake and blood biochemistry at energy measurement. The difference in npRQ and nonesterified fatty acid (NEFA) pre- and post-hepatectomy was shown as DeltanpRQ and DeltaNEFA, respectively. RESULTS: Compared with the preoperative values, npRQ significantly decreased in the Minor-highICG and Major-lowICG groups and NEFA significantly increased in the Major-lowICG group at postoperative day 14. In single regression analysis, DeltanpRQ significantly correlated with HCV infection and DeltaNEFA with resection volume, HCV infection, and ICGR15. In multiple regression analysis, DeltaNEFA significantly correlated with resection volume after adjusting for age, etiology, and ICGR15. CONCLUSIONS: These results suggest that postoperative nutritional recovery is slower in major resection than in minor resection patients. Hence, nutritional care to prevent starvation is needed in major resection patients. PMID- 29460799 TI - Customized nutrition intervention and personalized counseling helps achieve nutrition targets in perioperative liver transplant patients. AB - BACKGROUND AND AIM: Nutritional therapy is an integral part of care in all phases of liver transplantation (LTx). However, there are several factors that make it a challenge to manage malnutrition in these patients including, but not limited to, loss of appetite, dietary restrictions and dietary habits. Dietary habits are guided by personal choice, social, cultural and regional background with diversity ranging from veganism to vegetarianism with the latter predominant in Indian population. Therefore, it is difficult to improve nutritional intake of patients with standard dietary recommendations. We evaluated the effects of implementing personalized dietary counseling and a customized nutrition plan on its ability to enhance oral intake and, thereby improve nutritional status of patients with end stage liver disease (ESLD) being evaluated for LTx. We compared the outcomes with a matched group of patients who were prescribed standard dietary recommendations from a historic database. Primary outcome was measured by number of patients achieving >=75% of recommended energy and protein requirements during hospitalization for LTx. Secondary outcomes included mean energy and protein intake, hours of ventilation, length of stay in Intensive Care Unit (ICU) and hospital, mortality and readmission rate in the acute phase (3months) after LTx. METHODS: This was a prospective observational study, performed at a single LTx centre. All patients >18years who enrolled for LTx and consented for the study were included. The study was conducted after obtaining institutional ethics committee approval. A protocol based nutrition planning was implemented from April'14. According to this protocol, all patients being evaluated for LTx underwent a detailed nutritional assessment by a qualified Clinical Dietitian (CD) and regularly followed up with until LTx. Nutritional intervention, including a customized nutrition care plan and personalized dietary counseling, was provided based on the severity of malnutrition. To evaluate the efficacy of this protocol, we compared the nutritional adequacy (calorie and protein intake) of 65 consecutive patients who underwent LTx between August'14-October'15 (group 1) with a historic database of 65 patients who underwent LTx between January'13 and April'14 (group 2). Patients' demographics, disease severity score, baseline markers of nutritional status (subjective global assessment (SGA), and body mass index (BMI)), were recorded. First, assessment of individual patient's oral energy and protein intake was determined by the daily calorie count during hospitalization. Then the nutritional intervention (oral nutrition supplement (ONS)/enteral nutrition (EN)/parenteral nutrition (PN)) plan was customized according to their spontaneous oral intake. As part of the protocol, health related quality of life was also assessed using short form 8 (SF-8) in group 1. Statistical analyses using Pearson's correlation, Chi-Square test were applied with SPSS version 20.0. RESULTS: The mean age of group 1 and 2 were 52.6 +/- 9.8, 51.9 +/- 10.5 (range 25-70years) with BMI of 26.8 +/- 6.0, 26.5 +/- 5.4 respectively. According to SGA, there was significant improvement in the nutritional status of group 1 patients compared to group 2 on admission for LTx. It was indicated that 88% of group 1 individuals in comparison to 98% in group 2 were malnourished. The calorie intake of group 1 (1740.2 +/- 254.8) was significantly higher than group 2 (1568.5 +/- 321.6) (p = 0.005). The marked improvement in protein intake in group 1 (63.1 +/- 12.1) when compared with group 2 (53.1 +/- 13.4) was statistically significant (p = 0.008). A subset analysis showed that non-vegetarians (consuming meat and dairy products) between the groups showed that group 1 had a significantly higher calorie (p = 0.004) and protein (p = 0.0001) intake compared to individuals in group 2. Following implementation of study's protocol, the goal of achieving >=75% of the prescribed calories (p = 0.013) and protein (p = 0.0001) was significantly higher in group 1. CONCLUSION: When compared to the standard prescription, an individualized protocol to diagnose, stratify the severity of malnutrition early, and follow up by customized nutrition planning for patients helped to achieve nutritional targets more effectively. Inspite of patients' diversity in nutritional habits and reluctance to accept change, it is clear that a qualified and dedicated transplant nutrition team can successfully implement perioperative nutrition protocol to achieve better nutritional targets. PMID- 29460800 TI - Diet and cardiometabolic side effects in children treated with second-generation antipsychotics. AB - BACKGROUND: Second-generation antipsychotic (SGA) treatment in children is associated with metabolic side effects including weight gain, dyslipidemia, and insulin resistance. The objective of this study is to determine if SGA treatment in children affects dietary intakes and relationship to metabolic side effects. METHODS: Three-day food records assessed dietary energy and macronutrient intakes in a cross-sectional population of SGA-treated (n = 35) and SGA-naive (n = 29) children. RESULTS: SGA-treated children had more overweight/obesity (BMI >= 85th percentile for age and sex, p = 0.001); waist circumference (WC) >= 90th percentile for age and sex (p = 0.007); waist:height ratio (WHtR) >= 85th percentile for age and sex (p = 0.004), greater HOMA-IR, (p = 0.001) and plasma triglycerides (p = 0.017), and lower plasma HDL (p = 0.029). Dietary energy intakes were not different between SGA-naive and SGA-treated children [1734 +/- 486 vs 1971 +/- 649 (-135, 408) kcal/day, mean +/- SD (95% CI)] after adjustments for sex, age, Tanner stage, psychostimulant use, and height. Similarly, no differences in macronutrient intakes were observed. In models adjusted for SGA treatment and physical activity, no relationships between dietary intakes and BMI were found, but dietary total energy intakes were positively associated with waist circumference z-scores (p = 0.019), systolic blood pressure z-scores (p = 0.028, also adjusted for BMI) and HOMA-IR (p = 0.013, also adjusted for age, sex, BMI). All of the children had poor diets with 87.5% having >7% of daily energy from saturated fat; 62.5% having >20% of daily energy from sugar; and almost 60% having sodium intakes above the tolerable upper intake level. CONCLUSIONS: SGA treatment is not associated with greater dietary energy intakes in children. However, dietary energy intakes are associated with greater waist circumference and systolic blood pressure z-scores and HOMA-IR in children with mental health conditions. PMID- 29460801 TI - Effects of glucocorticoids on serum amino acid levels during cardiac surgery in children. AB - BACKGROUND AND AIMS: Children undergoing cardiac surgery with cardio pulmonary bypass often receive glucocorticoids to reduce the systemic inflammatory response. Glucocorticoids stimulate protein breakdown and increase amino acid availability. We studied whether glucocorticoid treatment influences the availability of amino acids, specifically those involved in the nitric oxide pathway. METHODS: We prospectively studied 49 children with congenital heart disease undergoing cardiac surgery. Serum cortisol and amino acid levels were measured in arterial blood sampled before surgery (t = -5 min), directly after surgery (t = 0 h) and at t = 12 h and t = 24 h after surgery. Serum cortisol and amino acid levels were compared between children who had received glucocorticoids (G+) and children who had not (G-). RESULTS: Of 49 patients included ((49% male, age 1.7 (0.5-8.7) y)), 33 (67%) received glucocorticoids. Baseline characteristics were not different between groups, except a higher weighted inotropic score in the G+ group. At t = 0 h, serum cortisol levels in the G+ group were significantly higher than in the G- group (7218 vs. 660 nmol/L; (p < 0.05)), but not different at the other time points. The levels of plasma amino acids had dropped after surgery. Compared to the G- group, in the G+ group the total amount of amino acids was significantly higher at t = 12 and t = 24; citrulline levels were higher at t = 12 and t = 24; and glutamine and arginine levels were higher at t = 12. CONCLUSIONS: Glucocorticoid treatment during cardiac surgery in children preserves serum amino acid levels post-surgery. The preservation of glutamine, citrulline and arginine levels might have a beneficial effect on the related NO metabolism. PMID- 29460802 TI - Can Quantab titrator sticks reliably predict urinary sodium? AB - BACKGROUND & AIMS: Urinary sodium concentration is a commonly used marker for extracellular fluid depletion which is often associated with dehydration. A point of care test for urinary sodium may reduce delays in clinical decision making by offering more timely guidance leading to improved salt and fluid management. We compared laboratory assessed urinary sodium with a potential point of care measure of urinary chloride in a variety of in- and outpatient specialities, to explore its use as an indicator of low urine sodium. METHODS: Urinary chloride concentrations were estimated using a Quantab titrator stick in samples from patients that had been sent for urinary sodium assays. We validated the results of this titrator stick with laboratory-assessed sodium concentrations by deriving correlation coefficients between these methods and using limits of agreement testing. We determined the optimal titrator stick cut-point for identifying low urinary sodium (urinary sodium <20 mmol/L) by maximising the product of the sensitivity and specificity. This level of urinary sodium was used to mirror the British Society of Gastroenterology guidance on short bowel patients Nightingale and Woodward, 2006. RESULTS: We obtained laboratory urinary sodium concentration and Quantab stick chloride measures on 127 samples. Twenty three percent had a urinary sodium below 20 mmol/L so were regarded as biochemically dehydrated. A threshold of <4.3 on the Quantab scale had a positive predictive value for low sodium of 56% (95%CI 40%-71%) and a negative predictive value of 94% (95%CI 87% 98%). CONCLUSIONS: These data suggest that the Quantab stick could be used as a point of care test to aid fluid and salt management decisions in an outpatient setting. Further work to explore the use of the titrator stick in specific patient populations at risk of salt and water depletion is justified. PMID- 29460803 TI - Vitamin D status in children with headache: A case-control study. AB - BACKGROUND: Vitamin D is a fat soluble vitamin with hormonal properties, plays crucial functions in bone and mineral metabolism and has important regulatory functions in brain development, cell differentiation and apoptosis. Some studies have shown a link between vitamin D deficiency and headache. MATERIAL AND METHODS: In this study, 147 patients with headache (migraine or either tension type headache (TTH)) and 69 healthy controls, aged 5 to 16 years, were evaluated. Each group was also divided into two separate sub-groups based on presentation to the clinic in either high solar-exposure (HSE) and low solar-exposure (LSE).We retrospectively evaluated the levels of calcium, phosphorus, alkaline phosphatase, parathyroid hormone, and 25-OH vitamin-D3. Levels below 20 ng/ml were described as vitamin D deficiency and levels of 2030 ng/ml as vitamin D insufficiency. RESULTS: The levels of 25-OH vitamin-D3 were statistically significantly lower when compared to the control group (17.1+/-9.4 vs. 25.8 +/- 12.8 ng/mL, respectively; p < 0.001). This held true for both the HSE and LSE group compared to the control group (for the group 1; 24.6 +/- 11.8 vs. 32.1 +/- 10.6 ng/mL, respectively; p = 0.007, and for the group 2; 14.5 +/- 6.8 vs. 19.6 +/- 13.5 ng/mL, respectively; p = 0.003). Also in headache subgroups (migraine and TTH), vitamin D levels were significantly lower than the control group (17.3 +/- 9.0, 16.9 +/- 9.9 and 25.8 +/- 12.8 ng/mL respectively; p < 0.001). CONCLUSION: There may be a relationship between vitamin D deficiency and headache, with particular significance in LSE. We suggest that this conclusion needs to be supported with randomised clinical studies containing a larger numbers of samples and controls. PMID- 29460804 TI - The costs of disease related malnutrition in hospitalized children. AB - INTRODUCTION: Disease related malnutrition (DRM) is a serious medical condition which is associated with an increase in morbidity and mortality, augmenting resource use and associated costs. DRM can be detected by actively and fully assessing the nutritional status. Studies in adult malnourished patients have shown that the additional health care costs are about ? 2 billion (? 2000 million) per year. The objective of the current study was to estimate the annual additional costs of DRM for pediatric patients as was done for adults. METHODS: A cost-of-illness analysis was performed to calculate the annual additional costs of DRM in 2015 pediatric patients (aged 1 month up to and including 17 years) admitted to non-academic hospitals in The Netherlands. DRM was assessed with weight-for-age, weight-for-height and height-for-age. Input variables in the formula used were length of stay and prevalence of DRM. The costs were estimated per disease as classified in the International Classification of Diseases by the WHO (ICD-10), per gender and age group. The results were expressed as an absolute monetary value as well as a percentage of the Dutch national health expenditure. Robustness of the results was checked by a sensitivity analysis. RESULTS: The total additional direct medical costs of DRM in pediatric patients in 2013 were estimated to be ? 51 million for acute malnutrition, ? 46 million when focused on chronic malnutrition and ? 80 million in case of overall malnourished children. This equals 5.6% of the total Dutch hospital costs for these hospitalized children. CONCLUSIONS: This study has shown that DRM in hospitalized children is associated with an increase in annual hospital costs with an additional amount of ? 80 million, of which acute malnutrition account for the largest part. PMID- 29460805 TI - Incidence of metabolic bone disease in preterm infants of birth weight <1250 g and in those suffering from bronchopulmonary dysplasia. AB - BACKGROUND & AIMS: Preterm infants are exposed to a higher risk of developing Metabolic Bone Disease (MBD) with an increased bone fragility, a higher fracture risk and a long-term reduced linear growth and childhood height. Monitoring bone growth has become mandatory in neonatology. Several risk factors have been identified among the population of extremely low birth weight infants, but we still do not know which is the real incidence of MBD since its evaluation is not routinely performed worldwide. The aim of this study was to evaluate the incidence of MBD in preterm infants and in those suffering from bronchopulmonary dysplasia (BPD). METHODS: Prospective evaluation of patients who developed BPD (BPD group) versus infants who did not develop it (no-BPD group). We examined, in preterms <1.250 g, the metacarpus bone transmission time (mc-BTT) at birth, 21 days and 36 weeks of gestational age (GA) together with biochemical markers of bone status. RESULTS: We included 135 patients, 55 with BPD. BPD patients received less total proteins in the first two weeks and less energy in the first month of life (p = 0.007 and p < 0.001 respectively). BPD patients had a worse growth velocity at two weeks of age (12.36 +/- 7.86 vs 16.59 +/- 7.05 g/kg/day, p = 0.001). At 21 days, BPD patients had lower phosphatemia (1.65 +/- 0.031 mmol/L vs 1.85 +/- 0.034 mmol/L, p = 0.007) and higher alkaline phosphatase levels (411.62 +/- 135.31 IU/l vs 338.98 +/- 102.20 IU/l, p = 0.005). BPD patients had significantly worse mc-BTT at 36 weeks GA (0.45 +/- 0.06 vs 0.50 +/- 0.08 MUsec, p < 0.001) and a higher incidence of MBD (60% vs 34%; p = 0.012). CONCLUSIONS: BPD infants are a special subset of patients among preterms who receive, in the first month of life, a lower energy intake than patients without BPD. BPD patients have a suboptimal bone growth and a higher incidence of MBD. Monitoring growth, bone status and optimizing nutritional intakes need to be further improved in preterm infants with BPD. PMID- 29460806 TI - Vitamin D deficiency and associated factors among pregnant women of a sunny city in Northeast of Brazil. AB - OBJECTIVE: We analyzed the serum vitamin D concentrations and identified the factors associated with vitamin D deficiency in Brazilian pregnant women, in a city with a high solar exposure. METHODS: Cross-sectional study with a sample of 190 pregnant women in a municipality in the Brazilian state of Bahia. Socio environmental information, regarding the lifestyle and biological factors of participants, was collected and recorded in a questionnaire, and serum concentrations of 25(OH)D was determined (PR). RESULTS: The deficient and insufficient vitamin D concentrations were found in 14.21% and 44.74% of the pregnant women, respectively. Vitamin D deficiency was associated with commuting to work via motor vehicles (PR: 2.79; 95% CI: 1.06-7.31), with winter (prevalence ratio - PR: 1.54; 95% CI: 1.01-2.35), exposure to the sun only on the face and hands (PR: 2.99; 95% CI: 1.35-6.63) and single pregnant women (PR: 2.53; 95% CI: 1.01-6.35). CONCLUSIONS: We detected a high proportion of pregnant women with vitamin deficient and insufficient vitamin D levels among pregnant women of a sunny city. These data suggest the necessity to monitor serum vitamin D levels during pregnancy and the adequate orientation in prenatal care to adoption healthy lifestyle for the prevention of vitamin D deficiency in this population. PMID- 29460807 TI - Improved nutrition for extremely preterm infants - A population based observational study. AB - BACKGROUND AND AIMS: Extremely preterm (EPT) infants are at high risk for malnutrition due to immaturity and medical complications and they often accumulate nutritional deficits and experience growth faltering during treatment at neonatal intensive care units (NICUs). Enhanced intake of energy and protein during the first weeks of life improves weight gain and head circumference growth. The optimal nutritional strategy for these infants' health and long-term development remains unknown. Nutritional regiments have been identified as a potential area for improvement in Swedish NICUs. The aim of this study was to evaluate changes in nutritional intake over time during the first 56 postnatal days in EPT (<27 gestational weeks; n = 316) infants, who were treated in NICUs during 2004-2011 in Stockholm, using a population-based study approach. METHODS: Several different nutritional interventions were implemented over the 8-year period. Nutrition and growth data were obtained retrospectively from hospital records. All intakes of enteral and parenteral nutrients were retrieved daily during the first 28 postnatal days and on days 35, 42, 49 and 56. RESULTS: Energy intake (median) increased from 77 kcal/kg/d during the 2004-2005 period to 98 kcal/kg/d during the 2010-2011 period on days 4-6. Median protein intake increased from 2.4 g/kg/d during 2004-2005 to 3.6 g/kg/d during 2010-2011. Energy and protein intake during postnatal days 0-6 increased continuously over the 8 years and protein intake increased during all 56 postnatal days. Full enteral feeds were reached earlier and the proportion of enteral feeds during the first week was higher during 2008-2009 compared to all other years. A significant improvement in growth was primarily noted by comparing the 2004-2005 period to subsequent years. CONCLUSIONS: Neonatal nutrition improved significantly in Stockholm from 2004 to 2011. Above all, parenteral nutrition was initiated more promptly during the first week and was provided at higher quantities. However, many of the EPT infants born during the later years still did not reach the recommended macronutrient intake levels. A significant weight gain improvement was observed between 2004-2005 and 2006-2011. PMID- 29460808 TI - Dietary poultry intake and the risk of stroke: A dose-response meta-analysis of prospective cohort studies. AB - BACKGROUND & AIMS: We performed a meta-analysis to illuminate and quantify the potential relationship between poultry intake and risk of stroke through summarizing available evidence using a dose-response meta-analysis of prospective cohort studies. METHODS: Pertinent prospective cohort studies attained using electronic searches through PubMed, and Scopus up to September 25th, 2017. Relative risks (RR) s with corresponding 95% confidence intervals (CIs) of the highest versus the lowest for cohort studies were evaluated using DerSimonian and Laird random-effects models to find combined RRs. We also assessed the dose response effect of this relationship. RESULTS: A total of 7 studies involving 354 718 participants were met inclusion criteria. The pooled RR of total stroke risk was [RR = 0.92 95% CI, 0.82, 1.03, I2 = 19.8%, Pheterogeneity = 0.28] for the highest versus lowest categories of poultry intake. Subgroup analysis showed an inverse associations for the US people [RR = 0.86 95% CI, 0.77, 0.95, I2 = 0.0%, Pheterogeneity = 0.38] and women [RR = 0.83, 95% CI, 0.72, 0.93, I2 = 0.0%, Pheterogeneity = 0.63]. We did not obtain any significant association in the subtypes of strokes with highest versus lowest poultry intake [Ischemic stroke (RR = 0.91; 95% CI: 0.79, 1.02, I2 = 0.0%, p = 0.93), Hemorrhagic (RR = 0.82; 95% CI: 0.59, 1.04, I2 = 20.5%, Pheterogeneity = 0.28)]. One serving per week increment in poultry intake was not associated with the risk of stroke (RR: 1.00, 95% CI: 0.96, 1.03, I2 = 69.0%, Pheterogeneity = 0.004). Nonlinear dose-response meta-analysis showed lower risk of stroke at consumption ~1 serving/week. CONCLUSION: Our meta-analysis revealed that poultry intake is not associated with total stroke risk; furthermore, an inverse relationship in US population and females must be interpreted with caution.

PMID- 29460810 TI - Consequences of an extreme diet in the professional sport: Refeeding syndrome to a bodybuilder. AB - Refeeding syndrome, as a life-threatening condition, is well known among severely malnourished or deeply metabolically stressed patients. This case presents an atypical manifestation of the syndrome to a young bodybuilder, whose extreme diet, including 5 months of insufficient nourishment before the sport competition and 6 days of carbohydrates overload afterwards, has led him to a bilateral lower - limb paralysis and drastic homeostatic disturbances. Severe hypokalemia, hypophosphatemia, hypomagnesemia and hyperglycemia with mildly elevated liver enzymes have occurred. The patient could barely move his legs and arms, and his state has been followed by a hypertensive crisis, which required an immediate intravenous treatment. Although his weight was 112,5 kg with a body mass index of 32,2 kg per square meter, and his blood serum albumin concentration resulted inside the normal range, the overall condition was corresponding to the state of extenuated and malnourished patients. This case reflects to high prevalence of eating disorders or non-adequate nutrition among weight-sensitive sport athletes. The importance of prevention and opportune diagnostics of refeeding syndrome among special vulnerable groups should be considered. PMID- 29460811 TI - Effects of a novel method for enteral nutrition infusion involving a viscosity regulating pectin solution: A multicenter randomized controlled trial. AB - BACKGROUND & AIMS: The initial complications associated with infusion of enteral nutrition (EN) for clinical and nutritional care are vomiting, aspiration pneumonia, and diarrhea. There are many recommendations to prevent these complications. A novel method involving a viscosity-regulating pectin solution has been demonstrated. In Japan, this method along with the other so-called "semi solid EN" approaches has been widely used in practice. However, there has been no randomized clinical trial to prove the efficiency and safety of a viscosity regulating pectin solution in EN management. Therefore, we planned and initiated a multicenter randomized controlled trial to determine the efficiency and safety. METHODS: This study included 34 patients from 7 medical institutions who participated. Institutional review board (IRB) approval was obtained from all participating institutions. Patients who required EN management were enrolled and randomly assigned to the viscosity regulation of enteral feeding (VREF) group and control group. The VREF group (n = 15) was managed with the addition of a viscosity-regulating pectin solution. The control group (n = 12) was managed with conventional EN administration, usually in a gradual step-up method. Daily clinical symptoms of pneumonia, fever, vomiting, and diarrhea; defecation frequency; and stool form were observed in the 2 week trial period. The dose of EN and duration of infusion were also examined. RESULTS: A favorable trend for clinical symptoms was noticed in the VREF group. No significant differences were observed in episodes of pneumonia, fever, vomiting, and diarrhea between the 2 groups. An apparent reduction in infusion duration and hardening of stool form were noted in the VREF group. CONCLUSIONS: The novel method involving a viscosity regulating pectin solution with EN administration can be clinically performed safely and efficiently, similar to the conventional method. Moreover, there were benefits, such as improvement in stool form, a short time for EN infusion, and a reduction in vomiting episodes, with the use of the novel method. This indicates some potential advantages in the quality of life among patients receiving this novel method. PMID- 29460812 TI - The acute effect of black tea consumption on resistance artery endothelial function in healthy subjects. A randomized controlled trial. AB - BACKGROUND & AIMS: Black tea is a main source of flavonoids in the Western diet and has been associated with reduced risk for cardiovascular disease, possibly through lowering blood pressure. These effects may be mediated through improving endothelial function of resistance arteries. The aim of this study was therefore to examine the acute impact of black tea on forearm resistance artery endothelial function in healthy, normotensive middle-aged subjects. METHODS: Twenty middle aged men and women (age-range 45-75 years) were recruited into a double-blind, randomized, placebo-controlled crossover intervention study. Forearm resistance artery blood flow (FBF, measured using venous occlusion plethysmography) in response to incremental doses of acetylcholine, sodium nitroprusside and L-NG monomethyl arginine were determined 2 h after consumption of either black tea containing ~400 mg flavonoids (equivalent to 2-3 cups of tea) or a taste- and color-matched placebo. RESULTS: The mean FBF-response to acetylcholine after tea consumption was 23% higher compared to the response after placebo (95% CI: -20%, +88%), but this difference did not reach statistical significance (P = 0.32). No significant differences in the FBF-responses to sodium nitroprusside and L-NG monomethyl arginine were found between the tea and placebo interventions (P = 0.96 and 0.74, respectively). Correcting FBF for changes in blood pressure did not alter the outcomes. CONCLUSIONS: We found no evidence that acute intake of black tea significantly altered endothelium-dependent vasodilation of forearm resistance arteries in healthy middle-aged subjects. Interventions with a longer duration of tea ingestion are required to further explore the (long-term) impact of tea flavonoids on blood pressure regulatory mechanisms. This trial was registered at clinicaltrials.gov as NCT02328339. PMID- 29460813 TI - Surplus vitamin B12 use does not reduce fatigue in patients with Irritable Bowel Syndrome or inflammatory bowel disease: A randomized double-blind placebo controlled trial. AB - OBJECTIVE: In non-conventional care, high doses of vitamin B12 supplementation are used for the treatment of fatigue even in case of normal vitamin B12 blood levels. We performed a randomized placebo controlled trial to investigate the effect of surplus oral vitamin B12 supplementation on fatigue in patients with IBS or IBD. METHODS: This randomized double-blind, placebo-controlled trial included 95 out-clinic IBS and IBD patients with deactivating fatigue and normal vitamin B12 blood levels (>=150 pmol/l) aged 18-65 years. Participants were randomly assigned to receive 1000 MUg vitamin B12 daily or a placebo supplement for 8 weeks. The primary outcome measure was fatigue (Checklist Individual Strength (CIS)). In addition, measures of quality of life and depression were examined. RESULTS: No significant difference in scores of the CIS subscale 'subjective fatigue' was observed between the intervention group and the control group with changes in scores of -8.1 +/- 9.5 and -8.3 +/- 10.6 (95% CI -11.65 to 6.71), respectively. The scores on the CIS subscale 'motivation' improved with a significant change in scores of -2.2 +/- 4.6 (95% CI -4.4 to -0.04). No significantly increased scores were observed for depression or quality of life in the intervention group compared to the control group. CONCLUSION: This study did not confirm the expected effect of non-conventional surplus vit B12 supplementation on fatigue in IBS or IBD patients. In addition, no positive effect was observed on depression or quality of life. We conclude that surplus treatment with vitamin B12 in IBS and IBD patients suffering from fatigue has no beneficial clinical effect. PMID- 29460814 TI - Smoking cessation contributes to weight gain in patients with hepatobiliopancreatic malignancy. AB - BACKGROUND & AIMS: The relationship between smoking cessation and weight gain is well recognized. However, there is no data currently available on the effect of smoking cessation on weight gain in patients with malignancy. The aim of this study was to clarify the body weight (BW) change after smoking cessation in patients with malignancy. METHODS: We retrospectively analyzed 159 subjects who underwent hepatobiliopancreatic surgery. The smoking status was determined using questionnaires administered at the initial presentation, and the candidates were divided into two groups: recent quitters and nonsmokers. The change in the BW was compared between these two groups. RESULTS: There were 134 subjects with malignant disease (84.3%), with a median age of 68 (range: 26-84) years. In the nonsmoker group, 28 of 116 subjects (24.1%) gained weight between the initial presentation and admission. In the recent quitter group, 12 of 18 subjects (66.7%) gained weight in the same period (P < 0.01). Regarding the change in the BW from the initial presentation, recent quitters gained more weight than nonsmokers (+1.7 kg [+2.7%] vs. -1.0 kg [-2.0%], P < 0.01). Furthermore, the improvement from the initial presentation was seen in a higher percentage of recent quitters than nonsmokers with respect to Onodera's prognostic nutritional index (61.1% vs. 36.2%, P = 0.04) and the controlling nutritional status score (38.9% vs. 19.3%, P = 0.07). CONCLUSIONS: Weight gain due to smoking cessation was observed even in patients with hepatobiliopancreatic malignancy. PMID- 29460815 TI - Phase angle is related to outcome after ICU admission; an observational study. AB - INTRODUCTION: Malnutrition at the time of ICU admission is associated with an increased morbidity and mortality. Malnutrition is most often assessed by a questionnaire but can also be determined with bio-impedance and measurement of phase angle. In a single-centre observational study we compared the percentage of malnutrition in patients admitted to our ICU, according to the Short Nutritional Assessment Questionnaire (SNAQ) with the phase angle measured with bio-impedance. Furthermore, we questioned whether malnutrition is related to outcome parameters. METHODS: In a 15 week period consecutive patients admitted to the ICU were included. Exclusion criteria included age <18 years, anatomical and/or neurological abnormalities of the limbs and an ICU stay less than 6 h. Bio impedance measurements were performed shortly after admission, the SNAQ was obtained from the patient or legal representative. Malnutrition is considered with a SNAQ >=2 or a phase angle of <5 degrees for men and <4.6 degrees for women. The study was approved by our local ethical committee (MCL, nWMO 77, April 18, 2015). RESULTS: 299 Patients were included (66% male, age 66 +/- 12 year, BMI 27 +/- 4 kg/m2 and APACHE II score 14 [11-17]), of which 64% elective and 36% acute admissions. Hospital mortality was 7.4%. Malnutrition was present in 16% according to the SNAQ and in 36% according to phase angle. There was a fair accordance between the SNAQ and phase angle. Phase angle was significantly higher in patients with a SNAQ score of 0-1 (5.5 degrees +/-1.3) in comparison with patients with a SNAQ score >=2 (4.4 degrees +/- 1.1) (p < 0.001). Logistic regression analysis showed a significant relation between SNAQ and BMI, malignant disease and hospital length of stay and between phase angle and age, sex, BMI, malignant disease, hospital length of stay and hospital mortality. CONCLUSION: Malnutrition was present in 16% according to the SNAQ and in 36% according to phase angle in our IC population. Malnutrition was associated with prolonged hospital length of stay. In this small population of mixed ICU patients, a low phase angle was found to independently predict hospital mortality. CLINICAL TRIALS. GOV NUMBER: NCT02911181. PMID- 29460816 TI - Chilli intake is inversely associated with hypertension among adults. AB - BACKGROUND & AIMS: This study aimed to examine the association between chilli intake and the incidence of hypertension in a Chinese adult population. METHODS: Adults aged 20-75 years in the China Health and Nutrition Survey were followed from 1991 to 2011. Dietary data were collected during home visits using a 3-day food record in 1991, 1993, 1997, 2000, 2004, 2006, 2009 and 2011. Cox regression was used in the analysis. Blood pressure was measured at each data collection point. RESULTS: 13,670 adults were followed for a median of 9.0 years. During 132,089 person years of follow-up 4040 subjects developed hypertension. Chilli consumption was inversely associated with the incidence of hypertension. The incidence rate of hypertension was 30.5, 33.4, 31.9, and 24.0 per 1000 person years among those who consumed no chilli or 1-20, 20.1-50, >=50.1 g/day respectively. Adjusting for age, gender, energy intake, sodium and fat intake, smoking, alcohol consumption and physical activity, those with increasing cumulative average chilli intake were less likely to develop hypertension: 0, 1 20, 20.1-50 and >=50.1 g/day had a hazard ratio (HR) for hypertension of 1.00, 0.80 (95%CI 0.73-0.88), 0.81 (0.73-0.89) and 0.65 (0.57-0.75) (p for trend <0.001) respectively. The association was independent of overall dietary patterns and BMI. There was no significant interaction between chilli intake and gender, income, education and residence (urban/rural) in relation to the risk of hypertension. CONCLUSIONS: Chilli intake is inversely associated with the risk of developing hypertension in Chinese adults. PMID- 29460817 TI - MaFOS-GDM trial: Maternal fish oil supplementation in women with gestational diabetes and cord blood DNA methylation at insulin like growth factor-1 (IGF-1) gene. AB - BACKGROUND: To evaluate the effects of maternal fish oil supplementation in women with gestational diabetes mellitus (GDM) on birthweight and DNA methylation at insulin like growth factor-1 (IGF-1) gene in their offspring. METHODS: Randomized controlled trial. A total of 120 women with GDM were randomized to one of the two groups between 24 and 28 weeks of the pregnancy: Group 1 (n = 52) received fish oil liquid softgel (Ocean plus(r)) and Group 2 (Placebo) (n = 68) sunflower oil liquid softgel. The birthweight and DNA methylation at IGF-1 gene of the offsprings were assessed. RESULTS: We observed a significant inverse association between fish oil use during pregnancy and birthweight (beta = -0.18, s.e.:125, P = .04), corresponding to a 250 g lower birthweight among infants born to fish oil users. This association didn't persist in multivariate analysis. Cord blood IGF-1 was lower in fish oil group (P = .001). Cord blood DNA methylation percentages at CpG-1044 and CpG-611 sites of IGF-1 gene promoter 1 (P1) region were higher in fish oil group compared to placebo group (P = .02 and P = .001, respectively). However, CpG-1044 and CpG-611 methylations were not associated to birthweight (beta = 0.04, s.e: 25.1, P = .66 and beta = 0.04, s.e: 22.7, P = 0.66, respectively). CONCLUSIONS: Maternal fish oil use has small effects on birthweight and DNA methylation when given to mothers with GDM at late pregnancy. Future studies are needed to show associations between maternal fish oil use and neonatal DNA methylations. CLINICAL TRIAL REGISTRATION: "Fish Oil Supplementation in Women with Gestational Diabetes". IDENTIFIER: NCT02371343. PMID- 29460818 TI - Sarcopenic obesity and health outcomes in patients seeking weight loss treatment. AB - AIM: To investigate the prevalence of sarcopenic obesity (SO) and its association with health outcomes in patients seeking weight loss treatment from a bariatric center. METHODS: In this retrospective study, patients [>=18 years old, body mass index (BMI) >=30 kg/m2] from the Tallahassee Memorial Bariatric Center and with baseline body composition assessment by bioelectrical impedance analysis were included. Fat mass index (FMI = fat mass/height2) and fat-free mass index (FFMI = fat free mass/height2) were calculated. SO was defined by a FMI/FFMI ratio greater than the 95 percentile of sex, BMI and ethnicity specific population representative references. Medical records were reviewed for biochemical and comorbidity measures. RESULTS: One hundred and forty-four patients (~69% females, mean age 55.6 years, mean BMI 46.6 kg/m2) were included. Patients' FMI/FFMI ratios ranged from 0.35 to 1.60 kg/m2 across body weight spectrum, with 51% having SO. Blood pressure, fasting glucose, triglycerides, HDL or LDL were not different between patients with and without SO. However, the prevalence of high cholesterol, asthma, alcoholism and hernia were higher in patients with SO. SO was the strongest univariate predictor of high cholesterol (OR = 2.08, 95% CI 1.07-4.04) and asthma (OR = 2.77, 95% CI = 1.12-6.83). CONCLUSION: SO was prevalent and associated with adverse health outcomes, beyond that captured by anthropometric measures in the present study. PMID- 29460819 TI - Effect of high dose vitamin D3 therapy on serum vitamin D3 levels in vitamin D insufficient adults with cystic fibrosis. AB - BACKGROUND: The effect of a high dose oral cholecalciferol repletion strategy in Vitamin D insufficient adults with CF is still unknown. Therefore, we assessed the effectiveness of our current approach, giving oral vitamin D3 supplementation at a dose of 10,000 IU from Monday to Friday for a total of 50,000 IU D3 weekly in vitamin D insufficient adult with CF. METHODS: We performed a retrospective chart review of all 59 adult CF patients between the ages of 17 and 64 years routinely followed at the CF Adult Program of Winnipeg Health Sciences Centre. Through consultation with the endocrinologist, our clinic vitamin D repletion protocol for treating CF adult patients who have serum 25-hydroxyvitamin D (25 OHD) < 30 ng/ml (<75 nmol/L) was to prescribe vitamin D3 10,000 IU orally from Monday to Friday (or the weekly equivalent of 50,000 IU) for 12 weeks in addition to their regular CF vitamin that supplied from 800 to 2000 IU vitamin D3 daily. Cholecalciferol was conveniently administered orally as either one capsule (oil based) 10,000 IU or one tablet (powder-based) 10,000 IU. All patients were instructed to obtain follow-up serum 25-OHD levels post completion of treatment. RESULTS: Of the 59 adult patients at our CF Clinic, 35 patients (59%) had below optimal serum 25-OHD levels. Of the 35 patients identified, 10 patients with insufficient serum 25-OHD levels between 10 and 30 ng/ml (25-75 nmol/L) fulfilled the inclusion criteria. A significant increase in serum 25-OHD levels was observed (P < 0.01) from mean value of 21.6 +/- 5.9 ng/ml (54.1 +/- 14.8 nmol/L) at baseline to 31.7 +/- 9.1 ng/ml (79.3 +/- 22.8 nmol/L) >= 2 months post intervention. The current treatment approach was successful in treating Vitamin D insufficiency in 70% of the patients with low 25-OHD levels. CONCLUSION: The results of this study demonstrate that a large number of adults attending Winnipeg Health Sciences Centre CF Clinic have serum 25-OHD levels below 30 ng/ml (75 nmol/L). This supports the need for dedicated and individualized approach to manage this condition. High dose therapy of vitamin D3, although a more aggressive treatment approach, may result in achieving optimal levels of serum 25 OHD in adults with CF. PMID- 29460820 TI - Association between mental disorders, cognitive disturbances and vitamin D serum level: Current state. AB - BACKGROUND & AIMS: Vitamin D deficiency has been identified as a global problem. Approximately 14% of the world population has inadequate vitamin D levels. This vitamin has been usually associated with bone disorders such as rickets, osteomalacia, and osteoporosis. However, these disorders present only a small part of all the disturbances which can be induced by its deficiency. Low serum vitamin D is associated with development of cardiovascular diseases, hypertension, neurodegenerative diseases, diabetes mellitus, metabolic syndrome and even cancer. This vitamin may be an important factor in the development of psychiatric illnesses, therefore clinicians should not leave this serious issue unresolved. The aim of this review is to describe the current data concerning the association between vitamin D serum levels, cognition and mental disorders. METHODS: We conducted a systematic bibliographical research, of PubMed, MedLine literature and Cochrane database without language restriction to identify all publications concerning this issue from 1995 to the first quarter of 2017. RESULTS: We found 48,937 articles concerning vitamin D, published during the last 22 years and 3 months (1995-2017). We selected only those publications focused on the association between vitamin D serum deficiency and mental disturbances (depression, schizophrenia, cognitive disturbances, attention deficit disorder, and autism). One hundred and sixty-seven papers were found suitable to our selection criteria. Careful evaluation of the relevant literature demonstrates that addition of vitamin D to conventional antidepressive agents can improve antidepressive effect in contrast to placebo. Regarding other mental conditions there are no clear-cut conclusions. CONCLUSIONS: An association between low vitamin D serum levels and different mental disorders was found. Yet, nonetheless there is no clear consensus that addition of vitamin D improves or is related to a beneficial effect on mental health. More randomized clinical control trials should be performed in order to reach evidence based conclusions. PMID- 29460822 TI - Optimum Number of Sweeps in Clinical OVEMP Recording; How Many Sweeps are Necessary? AB - OBJECTIVE: Ocular vestibular-evoked myogenic potentials (OVEMPs) in our hands provide us with reproducible and consistent results; however, it has been shown that the OVEMP amplitude decreases with increased stimulus duration. The exact number of stimuli for OVEMP recording is not consistent among the published papers describing this test. We aimed to determine the number of stimuli needed to produce a satisfactory OVEMP response and the consequences of a more prolonged stimulation to the OVEMP response. MATERIALS AND METHODS: We retrospectively analyzed 50 OVEMP patient recordings and found that the average number of sweeps carried out was 26. We carried out three different OVEMP recordings using our standard protocol of (1) a "standard" OVEMP protocol, in which we record until the OVEMP wave becomes obvious; (2) an OVEMP recording using our average of 26 sweeps; and (3) an OVEMP recording with twice as many sweeps. RESULTS: OVEMP latencies did not change when using different number of sweeps; however, the amplitudes showed a significant decrease with an increasing number of sweeps. CONCLUSION: OVEMPs can be completed in a satisfactory manner with a much lower number of stimuli than those usually carried out. Reducing the stimulus number reduces the time taken for the test, minimizes the cochlear insult while not reducing the valuable information obtained, and maximizes the amplitude of the stimulus, possibly increasing the accuracy of measuring interaural amplitudes and helping to measure asymmetry. PMID- 29460823 TI - Effect of Body Mass Index on Middle Ear Resonance Frequency. AB - OBJECTIVE: Multifrequency tympanometry (MFT) analyzes tympanograms obtained using different probe tones between 226 and 2000 Hz. An important parameter of MFT is resonance frequency (RF). Studies have recently demonstrated that the RF value can vary depending on many factors. To provide new data regarding MFT, middle ear RF values were investigated with regard to body mass index (BMI). MATERIALS AND METHODS: This study included 78 volunteers (i.e., 156 ears) aged 18-40 years who did not have hearing loss and whose otoscopic examinations were normal. Hearing thresholds were measured using pure tone audiometry, and RF values were recorded with immitansmetric measurements. The participants were divided into the following three groups according to their BMI: <18.5 kg/m2, Group 1; 18.5-24.9 kg/m2, Group 2; and >25 kg/m2, Group 3. The RF values were also analyzed. RESULTS: Although there was no significant difference between Groups 1 and 2 in terms of RF values, a significant difference was observed between Groups 1 and 3 and between Groups 2 and 3. CONCLUSION: In the light of these data, BMI values should be considered when middle ear RF values are assessed. PMID- 29460824 TI - Comparison of Cisplatin with Lipoplatin in Terms of Ototoxicity. AB - OBJECTIVE: Cisplatin (CDDP) is an anti-neoplastic agent that has been used in treatments of both pediatric and adult cancers. It has many side effects, such as ototoxicity, nephrotoxicity, and neurotoxicity. Lipoplatin (LIPO) is a nanomolecule with 110 nm diameter and composed of lipids and CDDP. In this study, we aimed to compare the toxic effects of LIPO with CDDP in the cochlear cells with anti-tumoral doses determined in neuroblastoma cells. MATERIALS AND METHODS: House Ear Institute Organ Corti 1 (HEI-OC1), MYC-N amplified KELLY, and MYC-N non amplified SH-SY5Y human neuroblastoma cells were used in this study. Firstly, anti-tumoral lethal dose 50 (LD50) of LIPO and CDDP were determined using the WST 1 assay in both neuroblastoma cells. Then anti-tumoral doses of CDDP and LIPO were applied on HEI-OC1 cells for evaluating the toxic effects. The apoptotic cell death was measured using flow cytometric analysis of annexin-V/7-amino actinomycin (7-AAD) and cell cycle tests. RESULTS: LIPO or CDDP inhibited cell viability in a dose- and time-dependent manner in both neuroblastoma and HEI-OC1 cells. LD50 values were selected as 20 mM for CDDP and 750 mM for LIPO in neuroblastoma cells. After the 48-hour incubation, KELLY cells treated with 20 mM CDDP and 750 mM LIPO had a 53% viability; SH-SY5Y cells treated 20 mM CDDP and 750 mM LIPO had a 45% and 58% viability, respectively; and HEI-OC1 cells treated with 20 mM CDDP and 750 mM LIPO had a 65% and 82% viability, respectively. CONCLUSION: LIPO showed less toxic effects in the HEI-OC1 cells compared to CDDP at anti-tumoral doses. PMID- 29460825 TI - The Predictability Precision of Superior Semicircular Canal Through Radiological Assessment and Microanatomical Dissection. AB - OBJECTIVE: There is still ongoing research on the relationship of arcuate eminence (AE) and superior semicircular canal (SSC). We aimed to evaluate the precision of predictability of SSC through the morphology of AE via radiological means. MATERIALS AND METHODS: This investigation is performed on 12 dry skulls belonging to Mersin University Medical Faculty department of anatomy. Computed tomography (CT) assessment is performed with 0.5-mm-thin sections temporal bone algorithm on dry skulls which were marked with fixated copper wire by scotch tapes on the most prominent part of the middle fossa floor assuming the location of AE. The data are reformatted on the workstation with vitrea 2.0. The distances of the determined three points including lateral (A), apical (B), and medial (C) of the SSC and the copper wire are measured radiologically. Also, the height between the most apical part of the SSC to the floor of the skullbase (H) is measured. The angles between the placed copper wires and the SSC (E) are calculated. The angle between SSC and the midpoint of the IAC (F) and SSC to the sulcus of the greater GSPN (G) were measured. The nearest distance was measured between the most posterior part of the SSC and the point marked by the perpendicular line drawn from the medial border of the petrous bone to the most posterior part of the internal auditory canal (IAC) (D). RESULTS: The right and left A, B, and C distances are 2.54+/- 2.75, 3.67+/-3.16, 5.85+/-3.77; 2.92+/ 2.24, 3.68+/-2.93, 6.09+/-3.40, respectively. We could not find any statistical significance when the right A, B, and C distances were compared with the left values. Examination of the values revealed that C distance is greater than the A distance of the same side both for right (p=0.040) and left (p=0.022) measurements. The calculated left and right E angles are 30.313+/-12.838, and 35.558+/-18.437 degrees, respectively. Statistical significance was not found between the right and left angles. The right and left F, G angles were 53.17, 47.25; 93.58, 100.92 degrees; and D distances are 8.01, 8.13 millimeters, respectively. Statistical significance was not found when right and left E, F, G angles and D distances were compared. Among 12 left and 12 right sides, the copper wire was found to be nearly overlapping to SSC in two in the right and only one in the left. CONCLUSION: This study reveals that there is a great variability predicting the exact location of SSC through the prominence of AE. Complementary studies are needed with greater number of dry skulls and cadavers. Comparison of different hypothesis including the effect of temporal lobe sulcus is to be discussed to better enlighten the exact relationship of the aforementioned anatomical structures. PMID- 29460826 TI - Defining Clinical-Posturographic and Intra-Posturographic Discordances: What Do These Two Concepts Mean? AB - The European Society for Clinical Evaluation of Balance Disorders - ESCEBD - Executive Committee meets yearly to identify and address clinical equilibrium problems that are not yet well understood. This particular discussion addressed "discordances" (defined as "lack of agreement") in clinical assessment. Sometimes there is disagreement between a clinical assessment and measured abnormality (ies); sometimes the results within the assessment do not agree. This is sometimes thought of as "malingering" or an attempt to exaggerate what is wrong, but this is not always the case. The Committee discussed the clinical significance of unexpected findings in a patient's assessment. For example intraposturographic discordances sometimes exhibit findings (eg performance on more difficult trials may sometimes be better than on simpler trials). This can be suggestive of malingering, but in some situations can be a legitimate finding. The extreme malingerer and the genuine patient are at opposite ends of a spectrum but there are many variations along this spectrum and clinicians need to be cautious, as a posturography assessment may or may not be diagnostically helpful. Sometimes there is poor correlation between symptom severity and test results. Interpretation of posturography performance can at times be difficult and a patient's results must be correlated with clinical findings without stereotyping the patient. It is only in this situation that assessment in a diagnostic setting can be carried out in an accurate and unbiased manner. PMID- 29460827 TI - Repeated Attacks of Dizziness Caused by a Rare Mitochondrial Encephalomyopathy. AB - Cases of dizziness caused by multiple sclerosis are commonly reported, but those caused by mitochondrial encephalomyopathy have been rarely reported. Particularly, the description of eye nystagmography (ENG) using caloric and optokinetic nystagmus tests has not been reported to date. We encountered the case of a 40-year-old woman with mitochondrial encephalomyopathy who visited us with the chief complaint of dizziness. At first, we considered multiple sclerosis based on the magnetic resonance imaging (MRI) findings and dizziness. Repeated attacks of dizziness and serum lactic acid levels suggested mitochondrial encephalomyopathy. A muscle biopsy confirmed the diagnosis. ENG findings suggested central vestibular disorder of the cerebellum and brainstem. This case suggests that we should not rule out the differential diagnosis of a very rare mitochondrial encephalomyopathy in patients who experience dizziness with MRI findings indicative of multiple sclerosis.

AB - The relationship between the amount of a target protein in a complex biological sample and its amount measured by selected reaction monitoring (SRM) mass spectrometry upon the affinity enrichment of target protein with aptamers immobilized on a solid phase was studied. Human thrombin added in known concentrations to cellular extracts derived from bacterial cells was used as model target protein. It has been demonstrated that the affinity enrichment of thrombin in cellular extracts by means of the thrombin-binding aptamer immobilized on the surface of magnetic microbeads results in an approximately 10 fold increase of the concentration of target protein and a 100-fold decrease of the low limit of a target protein concentration range where its quantitative detection by SRM is possible without an interference from other peptides present in a tryptic digest. PMID- 29460829 TI - [Quality control study of engineered skin tissue]. AB - OMERO service was used to annotate the cell line HaCaT microscope images by two independent expert groups. The images were obtained in the course of developing tissue-engineered epithelium which consisted of several layers of the keratinocytes. Evaluation of expert opinions was performed by calculation of specificity, sensitivity and accuracy. The best convergence of opinions (91%) was achieved for the confluence of the cell monolayers. Accuracy 70% was observed in determining the extent of cell differentiation after 10 days of incubation. The paper illustrates the usefulness of OMERO service for dynamic cross-validation of quality in the development and standardization of cell preparations. PMID- 29460830 TI - [Exocytosis of myeloperoxidase from activated neutrophils in the presence of heparin]. AB - Exocytosis of myeloperoxidase (MPO) from activated neutrophils in the presence of the anionic polysaccharide heparin was studied. It was determined that the optimal concentration of heparin (0.1 u/ml), at which there is no additional activation of cells (absence of amplification of exocytosis of lysozyme contained in specific and azurophilic granules). It was found that after preincubation of cells with heparin (0.1 u/ml) the exocytosis of MPO from neutrophils activated by various stimulants (fMLP, PMA, plant lectins CABA and PHA-L) increased compared to that under the action of activators alone. In addition, it was shown that heparin in the range of concentrations 0.1-50 u/ml did not affect on the peroxidase activity of the MPO isolated from leukocytes. Thus, the use of heparin at a concentration of 0.1 u/ml avoids the artifact caused by the "loss" of MPO in a result of its binding to neutrophils, and increases the accuracy of the method of registration the degranulation of azurophilic granules of neutrophils based on determination of the concentration or peroxidase activity of MPO in cell supernatants. PMID- 29460831 TI - [Isolation of extracellular micro-vesicles from cell culture medium: comparative evaluation of methods]. AB - Extracellular vesicles (EV) are secreted by cells of multicellular organisms. EV mediate specific mode of intercellular communication by "horizontal" exchange of substances and information. This phenomenon seems to have an essential biological significance and became a subject of intensive research. Biogenesis, structural and functional features of the EV is being commonly studies in in vitro condition. Several methods of EV isolation from cell culture medium are established, however selection of method might influence on obtained results. The choice of the optimal method depends usually from the amount of medium and the aims of the research while is still challenging issue. We performed a comparative analysis of four different methods of EV isolation from cell culture medium: differential ultracentrifugation, ultracentrifugation with a 30% sucrose/D2O "cushion", precipitation with plant proteins and immune-affinity capturing. EV isolated by different approaches were compared in terms of following parameters: size, concentration, morphology of EV, contamination by non-vesicular particles, content of exosomal tetraspanins on the EV surface, content of total proteins, RNA, and several glioma-associated miRNAs. Applied methods included nano-patricle tracking analysis (NTA), dynamic light scattering (DLS), cryo-electron microscopy, flow cytometry and RT-qPCR. On the base of obtained results, we developed practical recommendations that may help researchers to make a best choice of EV isolation method. PMID- 29460832 TI - [The effect of the biologically active additive epiphamine on antioxidant and NADPH-generating enzymes activity under experimental cerebral ischemia/reperfusion in rats]. AB - The effect of biologically active additive with immunomodulator properties epiphamine on the activity of antioxidant (superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, glutathione transferase) and NADPH generating (glucose-6-phosphate dehydrogenase, NADP-isocitrate dehydrogenase) enzymes has been investigated at experimental cerebral ischemia/reperfusion in rats. The results obtained indicate epiphamine-induced changes of these enzymes activities towards control values. Changes in the content of lactate, a marker of the pathology development, have also been found in experimental animals under ischemia and epiphamine administration caused changes similar to those observed in the case of enzyme activities studied. In most cases, the changes were dose dependent. Thus, epiphamine can be of considerable interest from the point of view of metabolic changes pharmacological correction at the development of the pathology accompanied by oxidative stress. PMID- 29460833 TI - [Representation analysis of miRNA from clarified urine and urine microvesicles in prostate malignancies and non-malignant neoplasms]. AB - Urine of prostate cancer patients contains tumor-specific biopolymers, including protein- and microvesiclesassociated miRNAs that can potentially be used as oncomarkers. Previously we have characterized urine extracellular vesicles and demonstrated diagnostic potential of their miRNA cargo. In this study, we have performed a comparative analysis of the expression of 84 miRNA in paired samples of urine microvesicles and clarified urine from healthy men, patients with benign hyperplasia and cancer of the prostate using miRCURY LNA miRNA qPCR Panels. Subsets of miRNAs with differences in expression between the fractions of the urine were found in all three groups. Two groups of miRNA were identified based on the patterns of their differential expression. They regulate several key signaling pathways associated with prostate cancer development.

AB - Matrix metalloproteinases (MMPs) responsible for the extracellular matrix remodeling, the activation of various growth factors, and angiogenesis play an important role in the colorectal cancer (CRC) development. In the present work the comparative analysis of MMP-7, -8, -9, and -11 mRNA as well mRNA of the Ki-67 proliferation marker in tissue samples obtained from CRC patients and healthy individuals. Employing the real time PCR method the expression levels of several MMPs (MMP-7, -8, -9, and -11) and cell proliferation marker, Ki-67, were simultaneously measured in 256 tissue samples obtained from 112 patients with CRC: 112 samples of the primary tumor (CRC), 112 samples of the most distant border of morphologically normal colonic mucosa (MNT), 16 samples of liver metastases) and from 16 healthy volunteers who underwent colonoscopy and biopsy. The expression of both MMPs studied and Ki-67 was found to be elevated in CRC primary tumors and liver metastases compared with the normal mucosa. CRC tumor and metastatic cells exhibited similar proliferative activity. The metastases are characterized by the highest cross-correlation of MMPs among tissue types tested. For the first time it was shown that normal mucosa from healthy individuals and CRC patients varied in the MMP-8 expression level. They also had dissimilar MMP correlation patterns thus suggesting that epithelial cells adjusted to CRC tumor differ from mucosal epithelial cells of healthy individuals.

AB - In the work a recombinant chemotaxis protein CheW from Thermotoga petrophila RKU 1 (TpeCheW) and its mutant homolog (TpeCheW-mut) were created. It was shown that, despite the low homology with CheW prototypes from intestinal bacteria, these proteins didn't cause metabolic overload and were well expressed by cells of E. coli laboratory strains. We have discovered a broad spectrum of industrial valuable properties of the TpeCheW-mut protein such as stability in a wide range of temperatures and pH, high expression level, solubility and possibility of the application of a simple low-stage purification methodology with the use of preliminary heat treatment. Possible directions of the scientific and industrial application of this protein were claimed. PMID- 29460836 TI - [Study specificity of isatin interactions with P450 cytochromes]. AB - Cytochrome P450-dependent monooxygenase systems exist basically in all living organisms, where they perform various important functions. The coordinated functioning of these systems involves many proteins participating in different protein-protein interactions (PPI). Previously, we have found that the endogenous non-peptide bioregulator isatin (indoledione-2,3), synthesized from indole by means of certain cytochromes P450 (e.g. P450 2E1, P450 2C19, P450 2A6) regulates affinity of some PPI. In this work, an attempt has been undertaken to register a direct interaction of isatin with a set of different proteins related to the functioning of cytochrome P450-dependent monooxygenase: five isoforms of cytochromes P450, two isoforms of cytochrome b5, cytochrome P450 reductase, adrenodoxin, adrenodoxin reductase and ferrochelatase. The study has shown that isatin binds specifically only to cytochromes P450 with high affinity (the equilibrium dissociation constant (Kd) is about 10-8 M).

AB - Literature data on influence of existing and new groups of drug preparations for dyslipidemias correction are systemized, and molecular mechanisms of their effects are reviewed. The results of experimental and clinical investigations aimed at revealing of new pharmacological targets of dyslipidemias correction were analyzed. The approaches for activation of high density lipoproteins functionality are described. The implementation of alternative preparations with new alternative mechanisms of action may be suggested to improve the effectiveness of traditional treatment in the future.

AB - Phospholipase D (PLD) is one of the key enzymes that catalyzes the hydrolysis of cell membrane phospholipids. In this review current knowledge about six human PLD isoforms, their structure and role in physiological and pathological processes is summarized. Comparative analysis of PLD isoforms structure is presented. The mechanism of the hydrolysis and transphosphatidylation performed by PLD is described. The PLD1 and PLD2 role in the pathogenesis of some cancer, infectious, thrombotic and neurodegenerative diseases is analyzed. The prospects of PLD isoform-selective inhibitors development are shown in the context of the clinical usage and the already-existing inhibitors are characterized. Moreover, the formation of phosphatidylethanol (PEth), the alcohol abuse biomarker, as the result of PLD-catalyzed phospholipid transphosphatidylation is considered.

The study of amyloid structures and their formation process was carried out for synthetic and recombinant Ab(1-40) and Ab(1-42) peptide preparations. In the study of these peptides, we recognized fibrils of different morphologies. We observed fibrillar formations in the form of single fibrils, ribbons, bundles, bunches, and clusters. Polymorphism of fibrils was observed not only when the environmental conditions changed, but under the same conditions and this was a common characteristics of all amyloid formations. Fibrils of Ab(1-40) peptides tended to form aggregates of fibrils in the form of ribbons, while Ab(1-42) peptide under the same conditions polymerized in the form of rough fibrils of different diameters and tends to branch. We assume that the formation of fibrils of Ab(1 40) and Ab(1-42) peptides occurs according to a simplified scheme: a destabilized monomer (r) a ring oligomer (r) a mature fibril consisting of ring oligomers. Proceeding from the proposition that the ring oligomer is the main building block of amyloid fibril (similar to the cell in the body), it is easy to explain fibril polymorphism, as well as fragmentation of mature fibrils under various external influences, branching and irregularity of diameter (surface roughness) of fibrils. One aspect of the study of amyloidogenesis is the determination of the regions of the protein chain forming the core of the amyloid fibril. We theoretically predicted amyloidogenic regions for two isoforms of Ab peptides capable of forming an amyloid structure: 16-21 and 32-36 residues. Using the method of tandem mass spectrometry, these regions were determined experimentally. It was shown that the regions of Ab(1-40) peptide from 16 to 22 and from 28 to 40 residues were resistant to the action of proteases, i.e. its formed the core of the amyloid fibril. For Ab(1-42) peptide the whole sequence is not available for the action of proteases, which indicates a different way of associating ring oligomers in the formation of fibrils. Based on electron microscopy and mass spectrometry data we proposed a molecular model of the fibril formed by Ab(1-40) and Ab(1-42) peptides.

AB - To increase the sensitivity and specificity of the developed methods for diagnosis of oncological diseases using exosomes of blood, a stage of pre selection of tumor exosomes from a common pool of circulating microvesicles is required. In the present work, universal proteins have been identified, their expression has been increased in the exosomes of patients with colorectal cancer, head and neck squamous cell carcinomas, and lung cancer. The use of antibodies against major exosomal proteins will further develop a simple and high performance method of affinity isolation of tumor exosomes.

AB - It was shown that the activator activity of protein C, determined in normal plasma using Aspergillus ochraceus protease, is comparable with the activity of commercial protease analogue from the South American copperhead venom (ProtacO). It was found that protease of A. ochraceus can be used to determine protein C in plasma with its reduced content similar to ProtacO. Comparison of the activator protein C activity of A. ochraceus protease and the commercial analogue showed some excess of the activator activity of the fungal preparation, which may make it a promising substitute for the snake activator in diagnostical kits for determining the protein C content in clinical laboratories.

AB - A change in the Kondo lattice behavior of bulk YbAl3 has been observed when the alloy is shaped into nanoparticles (~12 nm). Measurements of the electrical resistivity show inhibited coherence effects and deviation from the standard Fermi liquid behavior (T 2-dependence). These results are interpreted as being due to the effect of the disruption of the periodicity of the array of Kondo ions provoked by the size reduction process. Additionally, the ensemble of randomly placed nanoparticles also triggers an extra source of electronic scattering at very low temperatures (~15 K) due to quantum interference effects. PMID- 29460844 TI - Theoretical investigation of excitonic magnetism in LaSrCoO4. AB - We use the LDA+U approach to search for possible ordered ground states of LaSrCoO4. We find a staggered arrangement of magnetic multipoles to be stable over a broad range of Co 3d interaction parameters. This ordered state can be described as a spin-density-wave-type condensate of [Formula: see text] excitons carrying spin S = 1. Further, we construct an effective strong-coupling model, calculate the exciton dispersion and investigate closing of the exciton gap, which marks the exciton condensation instability. Comparing the layered LaSrCoO4 with its pseudo cubic analog LaCoO3, we find that for the same interaction parameters the excitonic gap is smaller (possibly vanishing) in the layered cobaltite.

AB - The thermal expansion coefficient of technologically relevant multicomponent cubic nitride alloys are predicted using the Debye model with ab initio elastic constants calculated at 0 K and an isotropic approximation for the Gruneisen parameter. Our method is benchmarked against measured thermal expansion of TiN and Ti(1-x)Al x N as well as against results of molecular dynamics simulations. We show that the thermal expansion coefficients of Ti(1-x-y)X y Al x N (X = Zr, Hf, Nb, V, Ta) solid solutions monotonously increase with the amount of alloying element X at all temperatures except for Zr and Hf, for which they instead decrease for [Formula: see text]. PMID- 29460842 TI - Engineering principles for guiding spheroid function in the regeneration of bone, cartilage, and skin. AB - There is a critical need for strategies that effectively enhance cell viability and post-implantation performance in order to advance cell-based therapies. Spheroids, which are dense cellular aggregates, overcome many current limitations with transplanting individual cells. Compared to individual cells, the aggregation of cells into spheroids results in increased cell viability, together with enhanced proangiogenic, anti-inflammatory, and tissue-forming potential. Furthermore, the transplantation of cells using engineered materials enables localized delivery to the target site while providing an opportunity to guide cell fate in situ, resulting in improved therapeutic outcomes compared to systemic or localized injection. Despite promising early results achieved by freely injecting spheroids into damaged tissues, growing evidence demonstrates the advantages of entrapping spheroids within a biomaterial prior to implantation. This review will highlight the basic characteristics and qualities of spheroids, describe the underlying principles for how biomaterials influence spheroid behavior, with an emphasis on hydrogels, and provide examples of synergistic approaches using spheroids and biomaterials for tissue engineering applications. PMID- 29460846 TI - Construction of a liver sinusoid based on the laminar flow on chip and self assembly of endothelial cells. AB - The liver is one of the main metabolic organs, and nearly all ingested drugs will be metabolized by the liver. Only a small fraction of drugs are able to come onto the market during drug development, and hepatic toxicity is a major cause for drug failure. Since drug development is costly in both time and materials, an in vitro liver model that can accelerate bioreactions in the liver and reduce drug consumption is imperative in the pharmaceutical industry. The liver on a chip is an ideal alternative for its controllable environment and tiny size, which means constructing a more biomimetic model, reducing material consumption as well as promoting drug diffusion and reaction. In this study, taking advantage of the laminar flow on chips and using natural degradable gel rat tail Collagen-I, we constructed a liver sinusoid on a chip. By synchronously injecting two kinds of cell-laden collagen, HepG2-laden collagen and HUVEC-laden collagen, we formed two collagen layers with a clear borderline. By controlling the HUVEC density and injection of growth factors, HUVECs in collagen formed a monolayer through self assembly. Thus, a liver sinusoid on a chip was achieved in a more biomimetic environment with a more controllable and uniform distribution of discrete HUVECs. Viability, album secretion and urea synthesis of the live sinusoid on a chip were analysed on days 3, 5 and 7 after collagen injection with acetaminophen treatment at 0 (control), 10 and 20 mM. The results indicated that our liver sinusoid on a chip was able to maintain bioactivity and function for at least 7 d and was beneficial for hepatotoxic drug screening. PMID- 29460847 TI - Local order and crystallization of dense polydisperse hard spheres. AB - Computer simulations give precious insight into the microscopic behavior of supercooled liquids and glasses, but their typical time scales are orders of magnitude shorter than the experimentally relevant ones. We recently closed this gap for a class of models of size polydisperse fluids, which we successfully equilibrate beyond laboratory time scales by means of the swap Monte Carlo algorithm. In this contribution, we study the interplay between compositional and geometric local orders in a model of polydisperse hard spheres equilibrated with this algorithm. Local compositional order has a weak state dependence, while local geometric order associated to icosahedral arrangements grows more markedly but only at very high density. We quantify the correlation lengths and the degree of sphericity associated to icosahedral structures and compare these results to those for the Wahnstrom Lennard-Jones mixture. Finally, we analyze the structure of very dense samples that partially crystallized following a pattern incompatible with conventional fractionation scenarios. The crystal structure has the symmetry of aluminum diboride and involves a subset of small and large particles with size ratio approximately equal to 0.5.

AB - We report on the nature of electron correlations in Fe1-x Co x Si ([Formula: see text]) using combined results of magnetization, specific heat and transport properties. Doping driven quantum critical point is observed to occur at [Formula: see text]. The magnetically unstable regime is identified to be centered around [Formula: see text] [[Formula: see text]]. The emergence of non Fermi liquid behaviors in x = 0.8 (near to ferromagnetic quantum critical point) and x = 0.9 (disorder-induced) compositions are discussed on the basis of the power-law dependence of susceptibility [Formula: see text] ([Formula: see text] for x = 0.8 and 0.55 for x = 0.9), specific heat [Formula: see text] ([Formula: see text] for x = 0.8 and 0.9) and resistivity [Formula: see text] ([Formula: see text] for x = 0.8 and 1.38 for x = 0.9). Further, a comprehensive classification of doping dependent physical properties of Fe1-x Co x Si is presented in the revisited temperature-composition (T-x) phase diagram. PMID- 29460850 TI - Self consistent field theory of virus assembly. AB - The ground state dominance approximation (GSDA) has been extensively used to study the assembly of viral shells. In this work we employ the self-consistent field theory (SCFT) to investigate the adsorption of RNA onto positively charged spherical viral shells and examine the conditions when GSDA does not apply and SCFT has to be used to obtain a reliable solution. We find that there are two regimes in which GSDA does work. First, when the genomic RNA length is long enough compared to the capsid radius, and second, when the interaction between the genome and capsid is so strong that the genome is basically localized next to the wall. We find that for the case in which RNA is more or less distributed uniformly in the shell, regardless of the length of RNA, GSDA is not a good approximation. We observe that as the polymer-shell interaction becomes stronger, the energy gap between the ground state and first excited state increases and thus GSDA becomes a better approximation. We also present our results corresponding to the genome persistence length obtained through the tangent tangent correlation length and show that it is zero in case of GSDA but is equal to the inverse of the energy gap when using SCFT. PMID- 29460849 TI - Calculations of spin-polarized Goos-Hanchen displacement in magnetically confined GaAs/Al x Ga1-x As nanostructure modulated by spin-orbit couplings. AB - We theoretically investigate Goos-Hanchen (GH) displacement by modelling the spin transport in an archetypal device structure-a magnetically confined GaAs/Al x Ga1 x As nanostructure modulated by spin-orbit coupling (SOC). Both Rashba and Dresselhaus SOCs are taken into account. The degree of spin-polarized GH displacement can be tuned by Rashba or Dresselhaus SOC, i.e. interfacial confining electric field or strain engineering. Based on such a semiconductor nanostructure, a controllable spatial spin splitter can be proposed for spintronics applications. PMID- 29460851 TI - Robust tunable excitonic features in monolayer transition metal dichalcogenide quantum dots. AB - The effects of quantum confinement on excitons in parabolic quantum dots of monolayer transition metal dichalcogenides (TMDC QDs) are investigated within a massive Dirac fermion model. A giant spin-valley coupling of the TMDC QDs is obtained, larger than that of monolayer TMDC sheets and consistent with recent experimental measurements. The exciton transition energy and the binding energy are calculated, and it is found that the strong quantum confinement results in extremely high exciton binding energies. The enormously large exciton binding energy in TMDC QDs ([Formula: see text] for different kinds of TMDC QDs) ensures that the many body interactions play a significant role in the investigation of the optical properties of these novel nanostructures. The estimated oscillator strength and radiative lifetime of excitons are strongly size-dependent and indicate a giant oscillator strength enhancement and ultrafast radiative annihilation of excitons, varying from a few tens of femtoseconds to a few picoseconds. We found that the spin-dependent band gap, spin-valley coupling, binding energy and excitonic effects can be tuned by quantum confinements, leading to tunable quantum dots in monolayer TMDCs. This finding offers new functionality in engineering the interaction of a 2D material with light and creates promise for the quantum manipulation of spin and valley degrees of freedom in TMDC nanostructures, enabling versatile novel 2D quantum photonic and optoelectronic nanodevices. PMID- 29460852 TI - Friction fluctuations of gold nanoparticles in the superlubric regime. AB - Superlubricity, or alternatively termed structural (super)lubrictiy, is a concept where ultra-low friction is expected at the interface between sliding surfaces if these surfaces are incommensurate and thus unable to interlock. In this work, we now report on sudden, reversible, friction changes that have been observed during AFM-based nanomanipulation experiments of gold nanoparticles sliding on highly oriented pyrolythic graphite. These effects can be explained by rotations of the gold nanoparticles within the concept of structural superlubricity, where the occurrence of ultra-low friction can depend extremely sensitively on the relative orientation between the slider and the substrate. From our theoretical simulations it will become apparent how even miniscule magnitudes of rotation are compatible to the observed effects and how size and shape of the particles can influence the dependence between friction and relative orientation. PMID- 29460853 TI - On-surface synthesis on a bulk insulator surface. AB - On-surface synthesis has rapidly emerged as a most promising approach to prepare functional molecular structures directly on a support surface. Compared to solution synthesis, performing chemical reactions on a surface offers several exciting new options: due to the absence of a solvent, reactions can be envisioned that are otherwise not feasible due to the insolubility of the reaction product. Perhaps even more important, the confinement to a two dimensional surface might enable reaction pathways that are not accessible otherwise. Consequently, on-surface synthesis has attracted great attention in the last decade, with an impressive number of classical reactions transferred to a surface as well as new reactions demonstrated that have no classical analogue. So far, the majority of the work has been carried out on conducting surfaces. However, when aiming for electronic decoupling of the resulting structures, e.g. for the use in future molecular electronic devices, non-conducting surfaces are highly desired. Here, we review the current status of on-surface reactions demonstrated on the (10.4) surface of the bulk insulator calcite. Besides thermally induced C-C coupling of halogen-substituted aryls, photochemically induced [2 + 2] cycloaddition has been proven possible on this surface. Moreover, experimental evidence exists for coupling of terminal alkynes as well as diacetylene polymerization. While imaging of the resulting structures with dynamic atomic force microscopy provides a direct means of reaction verification, the detailed reaction pathway often remains unclear. Especially in cases where the presence of metal atoms is known to catalyze the corresponding solution chemistry reaction (e.g. in the case of the Ullmann reaction), disclosing the precise reaction pathway is of importance to understand and generalize on-surface reactivity on a bulk insulator surface. To this end, density-functional theory calculations have proven to provide atomic-scale insights that have greatly contributed to unravelling the details of on-surface synthesis on a bulk insulator surface. PMID- 29460854 TI - Band structure and unconventional electronic topology of CoSi. AB - Semimetals with certain crystal symmetries may possess unusual electronic structure topology, distinct from that of the conventional Weyl and Dirac semimetals. Characteristic property of these materials is the existence of band touching points with multiple (higher than two-fold) degeneracy and nonzero Chern number. CoSi is a representative of this group of materials exhibiting the so called 'new fermions'. We report on an ab initio calculation of the electronic structure of CoSi using density functional methods, taking into account the spin orbit interactions. The linearized [Formula: see text] Hamiltonian, describing the anisotropic electronic structure of CoSi near the Gamma point is derived. The topological features of band-touching nodes with four- and six-fold degeneracy located at the Gamma and R points in the first Brillouin zone are analysed using the linearized Hamiltonians and first principle calculations. In particular, we show, using the non-Abelian Berry curvature, that these band-touching points carry topological charges of [Formula: see text], which change signs at certain values of parameters of the Hamiltonians. We describe the resulting Fermi arc surface states and their spin texture. We also discuss the influence of many body [Formula: see text] corrections on the electronic band structure and the topological properties of CoSi.

AB - Semiconductors composed of organic molecules are promising as components for flexible and inexpensive optoelectronic devices, with many recent studies aimed at understanding their electronic and optical properties. In particular, computational modeling of these complex materials has provided new understanding of the underlying properties which give rise to their excited-state phenomena. This article provides an overview of recent many-body perturbation theory (MBPT) studies of optical excitations within organic molecules and solids. We discuss the accuracy of MBPT within the GW/BSE approach in predicting excitation energies and absorption spectra, and assess the impact of two commonly used approximations, the DFT starting point and the Tamm-Dancoff approximation. Moreover, we summarize studies that elucidate the role of solid-state structure on the nature of excitons in organic crystals. These studies show that a rich physical understanding of organic materials can be obtained from GW/BSE.

AB - 7,8,15,16-tetraazaterrylene (TAT) thin films grown on highly oriented pyrolytic graphite (HOPG) substrates were studied extensively with regard to their intrinsic and interfacial electronic properties by means of ultraviolet photoelectron spectroscopy (UPS). Merely weak substrate-adsorbate interaction occurs at the TAT/HOPG interface, with interface energetics being only little affected by the nominal film thickness. Photon energy-dependent UPS performed perpendicular to the molecular planes of TAT multilayer films at room temperature clearly reveals band-like intermolecular dispersion of the TAT highest occupied molecular orbital (HOMO) energy. Based on a comparison with a tight-binding model, a relatively narrow bandwidth of 54 meV is derived, which points to the presence of an intermediate regime between hopping and band-like hole transport. Upon additional deposition of 2,2':5',2":5",2"'-quaterthiophene (4T), a 4T:TAT donor-acceptor bulk heterojunction with a considerable HOMO-level offset at the donor-acceptor interface is formed. The 4T:TAT bulk heterojunction likewise exhibits intermolecular dispersion of the TAT HOMO energy, yet with a significant decreased bandwidth. PMID- 29460857 TI - New developments in laser-based photoemission spectroscopy and its scientific applications: a key issues review. AB - The significant progress in angle-resolved photoemission spectroscopy (ARPES) in last three decades has elevated it from a traditional band mapping tool to a precise probe of many-body interactions and dynamics of quasiparticles in complex quantum systems. The recent developments of deep ultraviolet (DUV, including ultraviolet and vacuum ultraviolet) laser-based ARPES have further pushed this technique to a new level. In this paper, we review some latest developments in DUV laser-based photoemission systems, including the super-high energy and momentum resolution ARPES, the spin-resolved ARPES, the time-of-flight ARPES, and the time-resolved ARPES. We also highlight some scientific applications in the study of electronic structure in unconventional superconductors and topological materials using these state-of-the-art DUV laser-based ARPES. Finally we provide our perspectives on the future directions in the development of laser-based photoemission systems. PMID- 29460858 TI - Aedes vittatus (Bigot) mosquito: An emerging threat to public health. AB - Aedes vittatus (Bigot) mosquito is a voracious biter of humans and has a geographical distribution throughout tropical Asia, Africa and the Mediterranean region of Europe. It is predominantly a rock-hole breeder, though it can breed in diverse macro- and micro-habitats. The mosquito plays an important role in the maintenance and transmission of yellow fever (YFV), dengue (DENV), chikungunya (CHIKV) and Zika (ZIKV) viruses. It has been implicated as an important vector of YFV in several African countries as evidenced by repeated virus isolations from the mosquito and its potential to transmit the virus experimentally. Similarly, DENV-2 has been isolated from wild caught Ae. vittatus mosquitoes in Senegal, Africa which has been shown to circulate the virus in sylvatic populations without causing human infection. Experimental studies have shown replication of the virus at a low scale in naturally infected mosquitoes while high rate of infection and dissemination have been reported in parenterally infected mosquitoes. Natural isolation of ZIKV has been reported from Senegal and Cote d'Ivoire from these mosquitoes. They were found highly competent to transmit the virus experimentally and the transmission rate is at par with Ae. leuteocephalus, the primary vector of ZIKV. A few CHIKV isolations have also been reported from the mosquitoes in Senegal and other countries in Africa. Experimental studies have demonstrated high susceptibility, early dissemination and efficient transmission of CHIKV by Ae. vittatus mosquitoes. The mosquitoes with their high susceptibility and competence to transmit important viruses, viz. YFV, DENV, CHIKV and ZIKV pose a major threat to public health due to their abundance and anthropophilic behaviour. PMID- 29460859 TI - Improving vector-borne pathogen surveillance: A laboratory-based study exploring the potential to detect dengue virus and malaria parasites in mosquito saliva. AB - Background & objectives: Vector-borne pathogen surveillance programmes typically rely on the collection of large numbers of potential vectors followed by screening protocols focused on detecting pathogens in the arthropods. These processes are laborious, time consuming, expensive, and require screening of large numbers of samples. To streamline the surveillance process, increase sample throughput, and improve cost-effectiveness, a method to detect dengue virus and malaria parasites (Plasmodium falciparum) by leveraging the sugar-feeding behaviour of mosquitoes and their habit of expectorating infectious agents in their saliva during feeding was investigated in this study. Methods: Dengue virus 2 (DENV-2) infected female Aedes aegypti mosquitoes and P. falciparum infected female Anopheles stephensi mosquitoes were allowed to feed on honey coated Flinders Technical Associates -FTA(r) cards dyed with blue food colouring. The feeding resulted in deposition of saliva containing either DENV-2 particles or P. falciparum sporozoites onto the FTA card. Nucleic acid was extracted from each card and the appropriate real-time PCR (qPCR) assay was run to detect the pathogen of interest. Results: As little as one plaque forming unit (PFU) of DENV 2 and as few as 60 P. falciparum parasites deposited on FTA cards from infected mosquitoes were detected via qPCR. Hence, their use to collect mosquito saliva for pathogen detection is a relevant technique for vector surveillance. Interpretation & conclusion: This study provides laboratory confirmation that FTA cards can be used to capture and stabilize expectorated DENV-2 particles and P. falciparum sporozoites from infectious, sugar-feeding mosquitoes in very low numbers. Thus, the FTA card-based mosquito saliva capture method offers promise to overcome current limitations and revolutionize traditional mosquito-based pathogen surveillance programmes. Field testing and further method development are required to optimize this strategy. PMID- 29460860 TI - Aetiology of acute encephalitis syndrome in Uttar Pradesh, India from 2014 to 2016. AB - Background & objectives: It is imperative to know the aetiology of acute encephalitis syndrome (AES) for patient management and policy making. The present study was carried out to determine the prevalence of common aetiological agents of AES in Uttar Pradesh (UP) state of India. Methods: Serum and/or CSF samples were collected from AES patients admitted at Gandhi Memorial and Associated Hospital, King George's Medical University, Lucknow, a tertiary care centre, UP during 2014-16. Cerebrospinal fluid (CSF) and serum samples from cases were tested for IgM antibodies against Japanese encephalitis virus (anti-JEV), and dengue virus (anti-DENV) by ELISA; and for enterovirus, herpes simplex virus (HSV) and varicella zoster virus (VZV) by real-time PCR. Serum samples of cases having sufficient CSF volume, were also tested for anti-scrub typhus IgM antibodies and for Neisseria meningitides, Streptococcus pneumoniae and Haemophilus influenzae. Results: JEV and DENV (8% each) were the most common identified aetiology from the 4092 enrolled patients. Enterovirus, HSV and VZV, each were detected in <1% AES cases. Co-positivity occurred in 48 cases. Scrub typhus (31.8%) was the most common aetiology detected. Haemophilus influenzae and S. pneumoniae were detected in 0.97 and 0.94% cases, respectively, however, N. meningitides was not detected in any of the cases. About 40% of the JEV/DENV positive AES cases were adults. The gap between the total number of AES cases and those with JEV/ DENV infection increased during monsoon and post-monsoon seasons. Interpretation & conclusion: Scrub typhus, JEV and DENV are the main aetiological agents of AES in UP. DENV and JEV can no longer be considered paediatric diseases. The prevalence of non-JEV/DENV aetiology of AES increases in the monsoon and post-monsoon seasons. PMID- 29460861 TI - Immunogenicity of OmpA and OmpB antigens from Rickettsia rickettsii on mononuclear cells from Rickettsia positive Mexican patients. AB - Background & objectives: The nature of the rickettsial antigens and the immune response generated by them, have been the subject of exhaustive research so that a suitable vaccine can be developed. Till date evaluations of Rickettsia rickettsii antigens that induce both humoral and cellular responses in animal models have only shown partial protection and short-term immunological memory. This study was aimed to evaluate the immune response induced by DNA plasmids generated from the OmpA and OmpB genes of R. rickettsii in peripheral blood mononuclear cells of rickettsial (sensitized) patients compared to healthy subjects. Methods: Plasmids OmpA-49, OmpB-15 and OmpB-24 were generated in the pVAX vector. Macrophages derived from the THP-1 cell line were transfected in vitro with the plasmids and were co-cultured with T-lymphocytes from sensitized subjects and healthy subjects to evaluate cell proliferation and cytokine production. Results: The OmpB-24 plasmid induced proliferative response in human lymphocytes, with production of IL-2, IFN-gamma, IL-12p70, IL-6 and TNF-alpha, likely due to the presence of conserved epitopes among R. rickettsii, R. typhi and R. felis (differing from 1 to 3 amino acids) during the construction of the plasmids. Interpretation & conclusion: DNA sequences of rickettsial epitopes can be cloned into the pVAX vector. Constructed plasmids can generate a proliferative response and produce cytokines in vitro, in co-culture of transfected macrophages with sensitized human lymphocytes. Plasmid OmpB-24 proved to be the most immunogenic with respect to plasmids OmpA-49 and OmpB-15. PMID- 29460862 TI - Host preferences and feeding patterns of Anopheles sinensis Wiedemann in three sites of Shandong province, China. AB - Background & objectives: Anopheles sinensis Wiedemann is a major vector of malaria and is among the dominant species in Shandong province of China. Knowledge of the blood-feeding patterns of mosquitoes is crucial for elimination of malaria vectors. However, little information is available on the blood-feeding behaviour of An. sinensis mosquitoes in Shandong province. This study was carried out to compare the blood-feeding behaviour of An. sinensis in malaria-endemic areas of Shandong province China. Methods: Adult Anopheles mosquitoes were collected from three malaria-endemic areas (Jimo, Yinan and Shanxian), during the peak months of mosquito population (August and September) from 2014 to 2015. Indoor-resting mosquitoes and outdoor-resting blood-fed females were sampled in the morning hours (0600 to 0900 hrs) from 10 randomly selected houses using pyrethrum spray catch method, and sweeping with an insect net. ELISA was used for the identification of blood meal. The blood meal of each mosquito was tested against antisera specific to human, pig, dog, cow, goat, horse (mule) and fowl. Results: At all indoor study locations of Jimo, Yinan and Shanxian, 59.4, 68.1 and 98.8% blood-engorged female An. sinensis collected from cattle sheds fed almost exclusively on bovines, respectively. For outdoor locations, at Jimo site, 27.27 and 49.55% An. sinensis fed on cattle and pigs; at Yinan, 30.42% fed on cattle and 36.88% fed both on cattle and goats, while no pig antibodies were detected. At Shanxian, percent of An. sinensis that fed on cattle, pigs and cattle-goat was 20.72, 27.62 and 21.78%, respectively. Interpretation & conclusion: The analysis of An. sinensis blood meals in all the three studied areas from human houses, cattle sheds, pig sheds and mixed dwellings revealed that An. sinensis prefers cattle hosts, and can feed on other available animal hosts if the cattle hosts are absent, and the mosquitoes readily feed on humans when domestic animals (cattle and pigs) are not nearby for feeding. The analysis of blood meal revealed that An. sinensis follow opportunistic feeding in Shandong province, China. PMID- 29460863 TI - Entomological determinants of malaria transmission in an epidemic prone area of District Nuh (Haryana state), India. AB - Background & objectives: Entomological investigations were carried out in highly malarious villages under Ujina PHC of District Nuh (Haryana state) which is an epidemic prone area in northwestern region of India. The study was aimed to have an in-depth understanding of the entomological parameters influencing malaria transmission in the study area. Methods: The seasonal prevalence and biological attributes of vector mosquitoes were investigated during 2015 and 2016. Indoor resting vector mosquitoes were collected from human dwellings/cattle sheds and morphologically identified. Anopheles culicifacies were categorized to sibling species by species-specific inversions in polytene chromosomes and An. stephensi to ecological races on the basis of ridge number on egg float. The blood meal source analysis and incrimination studies of vectors were done by counter-current immunoelectrophoresis and enzyme-linked immunosorbent assay, respectively. Insecticide susceptibility test on vectors was performed as per WHO guidelines. Results: Seasonal abundance of An. culicifacies and An. stephensi in the study area showed variation; the peak densities of both the vectors were observed during monsoon months which correlated well with the average monthly rainfall data. Though both vectors were found to be primarily zoophagic, the human blood index of An. culicifacies (HBI = 0.17) was significantly higher than that of An. stephensi (HBI= 0.02). Analysis of sibling species composition of An. culicifacies population showed that it comprised almost of sibling species A (>98%) which is an established malaria vector. Anopheles culicifacies was incriminated for Plasmodium vivax and P. falciparum circumsporozoite (CS) antigen during monsoon months in 2015 and 2016. Assessment of insecticide susceptibility status of malaria vectors against 0.5% deltamethrin revealed that An. culicifacies is more susceptible (95% mortality) than An. stephensi (85% mortality). Interpretation & conclusion: The results suggest that An. culicifacies (species A) is playing a major role in malaria transmission in the study area and is almost susceptible to deltamethrin. Timely two rounds of indoor residual spray of synthetic pyrethroid with proper dosage and good coverage would be helpful in reducing vector population and consequently the malaria incidence. In addition, personal protection measures by the community would supplement the major intervention tool (IRS) in decreasing the man-vector contact. PMID- 29460864 TI - Serosurvey of Coxiella burnetii in high risk population in Turkey, endemic to Crimean-Congo haemorrhagic fever virus. AB - Background & objectives: Q fever caused by Coxiella burnetii is a zoonotic infection that spreads to human beings from animals. This study was aimed to demographically examine the C. burnetii seroprevalence in the people living in villages where Crimean-Congo haemorrhagic fever virus (CCHFV) is endemic, in terms of various risk factors such as tick bites, tick contact, and occupational groups. Methods: A total of 440 serum samples from those living in rural areas of Sivas and Tokat regions in Turkey were included in the study as a risk group; 387of them were serologically CCHFV positive (as confirmed in our previous research). Serums of the control group composed of 110 people living in urban areas. In all serum samples, IgG antibodies of C. burnetii against phase-I and phase-II antigens were diagnosed using the ELISA method. Results: Coxiella burnetii seropositivity was detected in 19.09% of those living in rural areas and 4.55% of those living in urban areas (p < 0.001, OR = 4.96). In terms of their approach to the ticks, no statistical difference was observed between the risk groups in the chi-square test (p = 0.787). However, according to univariate analysis, the absorbance means of antibodies reactive to C. burnetii was statistically higher for the rural people who have made contact with ticks than those who have not (p = 0.017). No seroepidemiological relation was found between CCHFV and C. burnetii serology (p = 0.787), and the rate of co-seropositivity between them was 5.43% (21/387). Interpretation & conclusion: The findings of the study showed that C. burnetii infection is epidemic especially in the people living in rural areas. Contact with ticks in various ways might have resulted in the increased risk of C. burnetii infection in the study. Personal protective measures against tick bites may be important for reducing Q fever risk as in other tick-borne infectious disease. PMID- 29460865 TI - The first positive serological study on rift valley fever in ruminants of Iran. AB - Background & objectives: Rift Valley fever (RVF) is a zoonotic vector-borne disease that primarily affects domestic animals but can also infect humans. The purpose of the present study was to investigate the presence of antibodies against RVF virus (RVFV) in ruminants, viz. cattle, sheep, and goats in Kurdistan Province of western Iran. Methods: Blood samples were collected from 288 ruminants (118 cattle, 142 sheep and 28 goats) of both sexes, under age groups <=1, 1-3, 3-5 and >=5 yr, from January 2016 to December 2016. Clinical symptoms and history of abortion were recorded. The presence of RVFV-specific antibodies was investigated by using ELISA (competitive) and indirect immunofluorescence assay (IIFA) after separation of serum. Results: The results of two tests were positive for five (1.74%) of total 288 animals which included two cattle of 118 (1.7%), and three sheep of 142 (2.11%). The results of IIFA were correlated with the ELISA results. All animals were clinically normal. No significant relationship between the RVFV infection rate and the variable considered, i.e. season, animal's age or sex, and the species of the animal (p >= 0.05), although there were four seropositive animals in the age group 1-3 and five seropositive animals in the spring season. Interpretation & conclusion: The results of the study revealed the presence of low-level RVFV circulation among the ruminants of Kurdistan Province in Iran indicating that they are at risk of exposure to the virus during their lifetime. Since the present study was the first serological study on RVF in Iran with positive results, further studies are suggested including other areas of Iran. PMID- 29460866 TI - Vector prevalence and detection of Crimean-Congo haemorrhagic fever virus in Golestan Province, Iran. AB - Background & objectives: Crimean-Congo haemorrhagic fever virus (CCHFV) causes severe disease with fatality rate of 30%. The virus is transmitted to humans through the bite of an infected tick, direct contact with the products of infected livestock as well as nosocomially. The disease occurs sporadically throughout many of African, Asian and European countries. Different species of ticks serve either as vector or reservoir for CCHFV. This study was aimed to determine the prevalence of CCHFV in hard ticks (Ixodidae) in the Golestan Province of Iran. Methods: A molecular survey was conducted on hard ticks (Ixodidae) isolated from six counties in Golestan Province, north of Iran during 2014-15. The ticks were identified using morphological characteristics and presence of CCHFV RNA was detected using RT-PCR. Results: Data revealed the presence of CCHFV in 5.3% of the ticks selected for screening. The infected ticks belonged to Hyalomma dromedarii, Hy. anatolicum, Hy. marginatum and Rhipicephalus sanguineus species. Interpretation & conclusion: The study demonstrated that Hyalomma ticks are the main vectors of CCHFV in Golestan Province. Thus, preventive strategies such as using acaricides and repellents in order to avoid contact with Hyalomma ticks are proposed.

PMID- 29460867 TI - Leishmaniasis in northern Cyprus: Human cases and their association with risk factors. AB - Background & objectives: Cyprus is located in the eastern part of the Mediterranean Region where leishmaniasis is endemic. The primary objective of this study was to investigate human visceral leishmaniasis (VL) in the northern region of Cyprus where presence of canine leishmaniasis (CanL) and sandflies has been documented in earlier studies. The secondary objective was to assess the association of leishmaniasis with demographic and epidemiological variables. Methods: Intravenous blood samples were collected from 249 volunteers in Kyrenia district (located in the northern coastal region of Cyprus). Whole blood samples were tested for DNA of Leishmania spp by polymerase chain reaction (PCR), while serum samples were analyzed using direct agglutination test (DAT) and rK39 test. For evaluation of possible risk factors, a questionnaire was applied to the participants. Results: Only three (1.2%) of 249 participants were found seropositive by DAT (n = 2) or rK39 test (n = 1). The remaining samples were negative in serology, and no PCR positivity was detected in any of the 249 participants. Seven individuals, including the seropositive cases, had a history of cutaneous leishmaniasis (CL). Seropositivity and CL were not significantly related with gender (M/F: 40.2/59.8%), age [Mean: 42.85 +/- 17.45, Median: 40 (7 86)], occupation (Indoor/Outdoor: 84.7/12.9%), dog ownership (52.6%), and CanL history (5.3%). However, a statistical association was found between seropositivity and past CL infection. Also, a significant relation was observed between participants living in peripheral area (63.1%) and CL infection. Furthermore, leishmaniasis awareness (28.1%) among the study population was statistically correlated with past CL infection and dog ownership. Interpretation & conclusion: This study demonstrates the presence of leishmaniasis and highlight the need for implementation of efficient control measures on the northern coast of Cyprus.

PMID- 29460873 TI - Thoracoscope-Assisted Mitral Valve Replacement with a Small Incision in the Right Chest: A Chinese Single Cardiac Center Experience. AB - BACKGROUND The aim of this study was to investigate the safety, feasibility, and clinical effectiveness of thoracoscopy-assisted mitral valve replacement via thoracic right-anterior minimal incision. MATERIAL AND METHODS A retrospective analysis was conducted of 225 patients with mitral valve lesions who were treated in our hospital from August 2012 to August 2015. Group A included 105 patients undergoing thoracoscopy-assisted mitral valve replacement via a thoracic right anterior minimal incision, and group B included 120 patients undergoing conventional mitral valve replacement. We collected and analyzed clinical data from both groups. RESULTS The procedures were successful in patients of both groups. No severe complications or mortality were reported. Postoperative mechanical ventilation time (8.6+/-2.4 h vs. 12.4+/-3.2 h), duration of intensive care (1.7+/-1.2 d vs. 2.8+/-1.3 d), duration of postoperative analgesia use (28.7+/-8.9 h vs. 36.3+/-7.5 h), postoperative length of hospital stay (8.2+/-2.2 d vs. 12.8+/-2.1 d), pleural fluid drainage (210.5+/-60.5 ml vs. 425.4+/-75.6 ml), blood transfusion amount (420.5+/-80.4 ml vs. 658.3+/-96.7 ml), and operative incision length (4.7+/-1.1 cm vs. 22.4+/-2.5 cm) were significantly shorter (or lower) in group A than in group B. There were different advantages and disadvantages in the 2 kinds of operative procedure in terms of postoperative complications. CONCLUSIONS Thoracoscopy-assisted mitral valve replacement via thoracic right-anterior minimal incision has the same clinical efficacy, safety, and feasibility as conventional mitral valve replacement. PMID- 29460874 TI - [Robot-assisted atrial septal defect closure in adults: first experience in Russia]. AB - AIM: To analyze immediate results of minimally invasive robot-assisted atrial septal defect (ASD) closure in adults. MATERIAL AND METHODS: For the period from March 2012 to November 2016 sixty patients with contraindications to endovascular procedure have undergone robot-assisted atrial septal defect closure at Meshalkin Siberian Federal Biomedical Research Center. Mean age was 34.5+/-11.3 years, body mass index - 24.6+/-4.0 kg/m2. 48 (80%) patients had NYHA class II before surgery. In 37 (61.7%) patients isolated ASD with deficiency or absence of one edge was diagnosed, isolated ASD with primary septum aneurysm - in 16 (26.7%) cases, 7 (11.6%) patients had reticulate ASD. 5 (8.3%) patients had concomitant tricuspid valve insufficiency required surgical repair (suture annuloplasty). All operations were performed under cardiopulmonary bypass with peripheral cannulation. Right-sided anterolateral mini-thoracotomy was used in the first 43 patients. Following 17 patients underwent completely endoscopic procedure. Depending on the shape, size and anatomical features of the defect we performed suturing (14 patients, 23.3%) or repair with xenopericardial patch (46%, 76.6%). RESULTS: Mean CPB and aortic cross-clamping time was 89.1+/-28.7 and 24.8+/-9.5 min, respectively. Postoperative variables: mechanical ventilation 3.3+/-1.5 hours, ICU-stay - 18.2+/-3.7 hours, postoperative hospital-stay - 13.4+/-5.7 days. There were no mortality and any life-threatening intra- and postoperative complications. Cases of conversion to thoraco-/sternotomy and postoperative bleeding followed by redo surgery were also absent. 23 patients were followed-up within 1 year, 6 patients - within 2 years, 3 patients - within 3 years. All patients were in NYHA class I-II with 100% freedom from ASD recanalization and redo surgery. According to echocardiography data there were decreased right heart, pulmonary artery pressure and preserved left ventricular function in early postoperative period and 1 year after surgery. CONCLUSION: In view of favorable course of postoperative period, no significant specific complications and encouraging immediate results we can talk about endoscopic robot-assisted ASD closure in adults as a safe and effective alternative to surgical treatment. PMID- 29460876 TI - [Thoracoscopic repair of postoperative intrapleural complications]. AB - AIM: To justify and develop the indications for thoracoscopic procedures in patients with complications after advanced cardiothoracic surgery including combined and simultaneous operations. MATERIAL AND METHODS: From 2013 to 2017 was performed treatment of complication in 27 patients undergoing various cardiothoracic intervention with the use of thoracoscopic technology. RESULTS: We have analyzed immediate results of thoracoscopic operations in 27 patients with various intrapleural complications after advanced cardiothoracic surgery. Satisfactory results of these interventions confirm safety of thoracoscopic technologies and serve as an argument in favor of this direction in thoracic surgery. PMID- 29460875 TI - [Staged approach for hybrid thoracoabdominal aortic replacement]. AB - AIM: To generalize our experience of step-by-step hybrid thoracoabdominal aortic replacement. MATERIAL AND METHODS: Twenty-three patients were enrolled who underwent staged hybrid treatment of thoracoabdominal aortic aneurysm. There were 5 (21.7%) women and 18 (78.3%) men aged 61.4+/-8.3 years (37-74 years). The first stage was proximal debranching, the second - distal (abdominal) procedure and the third - stenting of the thoracoabdominal aorta. RESULTS: There were no any complications after proximal debranching and aortic stenting. Abdominal debranching was followed by lethal outcome in 3 (13.0%) patients and early postoperative occlusion of the prosthesis brunch in 3 out of 87 cases. CONCLUSION: Staged approach for hybrid surgical treatment is optimal solution, especially in high risk patients. In our opinion no necessity for cardiopulmonary bypass is the main advantage of this technique. PMID- 29460877 TI - [Associated Liver Partition and Portal vein ligation for Staged hepatectomy (ALPPS) in focal liver diseases management]. AB - AIM: To determine ALPPS advisability in small future remnant liver. MATERIAL AND METHODS: 22 ALPPS procedures were performed at the Center for Surgery and Transplantology for the period from 2011 to 2016. Indications were both tumoral and non-tumoral unresectable liver diseases. Postoperative complications were classified according to Clavien-Dindo, ISGLS. RESULTS: According to CT-volumetry future remnant liver before the 1st stage of ALPPS was from 17 to 25%, before the 2nd stage - from 28 to 49%. Both stages were carried out in all patients with R0 resection in 100%. Postoperative complications were diagnosed in 40.9%, 1 death was caused by severe pulmonary embolism. Follow-up varied from 3 to 48 months (median 17.5), 86% of patients are alive at present. CONCLUSION: ALPPS provides rapid and effective FLR growth and can be used for both tumoral and non-tumoral unresectable liver diseases. However, ALPPS should be performed strictly according to indications and only in specialized centers with extensive experience of advanced liver resection and transplantation after previous comprehensive selection of patients.

MATERIAL AND METHODS: For the period from August 2012 to May 2017 Frey procedure was carried out in 31 patients with chronic calculous pancreatitis Buchler type C. There were 20 men and 11 women aged 48.6+/-9 years. Mean pancreatic head dimension was 35.5+/-14 mm, diameter of the main pancreatic duct - 9.6+/-2.7 mm. RESULTS: Completely laparoscopic procedure was made in 28 (90.3%) cases. One patient required intraoperatively Beger's technique without conversion. The last was need in 2 (6.5%) cases. Time of surgery and blood loss were 447.3+/-90.4 min and 215+/-177.7 ml respectively. Mean postoperative hospital-stay was 8.4+/-4.5 days. Postoperative complications occurred in 7 patients. Mortality was absent. Follow-up was 1-41 months. Recurrent pain syndrome was observed in 1 case. However, it was less severe and does not require analgesia. PMID- 29460879 TI - [Non-functioning gallbladder as a risk factor for bile ducts injury during laparoscopic cholecystectomy]. AB - AIM: To analyze the effect of gallbladder's morpho-functional changes as a risk factor for injury of extrahepatic bile ducts during cholecystectomy. MATERIAL AND METHODS: Laparoscopic cholecystectomy was performed in 20 564 patients. There were 147 64 (71.8%) patients with chronic gallbladder inflammation and 5800 (28.2%) - with acute process. It was performed a retrospective analysis of the incidence and causes of intraoperative trauma of extrahepatic bile ducts and bile outflow. Two groups of comparison were distinguished: acute calculous cholecystitis and chronic inflammation. RESULTS: There were 93 (0.04%) complications followed by bile outflow (55 (0.94%) in the 1st group and 38 (0.25%) in the 2nd group). Marginal injury of the ducts was interoperatively detected in 5 patients of group 1 and 3 patients of 2 groups. In postoperative period it was found in 6 patients of the 1st group due to electric trauma of common bile duct. Complete transection of common bile duct occurred in 10 (8.8%) cases, while chronic calculous cholecystitis was observed in 8 of them. At the same time, in 6 patients these were surgical interventions in scleroatrophic gallbladder. As a results, we determined the forms of non-functioning gallbladder with morphofunctional changes which promote trauma of extrahepatic bile ducts. CONCLUSION: Long-term non-functioning gallbladder leads to cicatricial and adhesive processes in its wall and surrounding tissues that significantly complicates cholecystectomy and increases the risk of bile ducts trauma. Scleroatrophic gallbladder is the most dangerous which occurs in 4.1% of patients with chronic calculous cholecystitis. Further trials are advisable to develop optimal therapeutic and diagnostic tactics for various forms of long-term non functioning gallbladder. PMID- 29460880 TI - [Outcomes of cardiac achalasia grade II-III management]. AB - AIM: To analyze early and remote results of the new method of cardiac achalasia grade II-III management. MATERIAL AND METHODS: Original surgical approach was applied in 21 patients with cardiac achalasia grade II-III. RESULTS: There were no any specific postoperative complications and deaths. Exacerbation of chronic pancreatitis, acute stomach ulcer and biliary peritonitis were observed in 3 cases respectively. All patients were followed-up within the period from 1.5 months to 5 years after surgery. Recurrent disease was absent. All employable patients have backed to work. CONCLUSION: According to clinical and instrumental data original surgical repair completely cures the symptoms of cardiac achalasia and restores normal esophageal dimensions and structure early after intervention.

MATERIAL AND METHODS: The procedure was performed in 50 women aged 22 to 51 years (35.1+/ 2.6 years). RESULTS: There were no any complications immediately after vacuum resection. Tissue of the neoplasm was removed in full in all patients. Benign and malignant tumors were observed in 94 and 6% cases respectively. All cases were identified in BIRADS category 3. CONCLUSION: Vacuum-aspiration resection is of great importance in the diagnosis and treatment of focal dysplasia of the mammary glands. It has a high diagnostic accuracy, allows you to remove focal disease in full without serious complications. PMID- 29460882 TI - [Results of video-assisted technologies in colorectal surgery]. AB - AIM: To analyze immediate outcomes of 286 laparoscopic and robot-assisted interventions on the colon and rectum. MATERIAL AND METHODS: There were 256 (89.51%) laparoscopic and 30 (10.49%) robot-assisted procedures. 233 (81.46%) operations were performed for rectum and colon cancer. Postoperative complications after colon cancer surgery were revealed in 11.11%, including anastomosis failure in 2.08% of cases. Postoperative complications after rectal cancer surgery occurred in 32.58% of cases including anastomosis failure after anterior rectectomy in 11.67%. CONCLUSION: Robot-assisted surgery is not advisable for colon diseases according to price-effectiveness ratio due to available laparoscopic approach. Preventive intestinal stoma in endoscopic low and ultra-low anterior rectal resection allows you to avoid clinically significant inconsistency of colorectal anastomosis. Laparoscopic procedure should be performed with Contour stitching-cutting device in low and ultra-low anterior rectal resection if there is technical complexity of one-stage rectum intersection below the tumor. Robot-assisted operations for rectal cancer have advantages due to three-dimensional imaging and better orientation, greater freedom of manipulation in confined spaces, and simplicity of lymphadenectomy. PMID- 29460883 TI - [Efficacy of video-assisted procedures in advanced age patients with colorectal cancer]. AB - AIM: To assess advisability of video-assisted surgery in advanced age patients with colorectal cancer. MATERIAL AND METHODS: The study involved 44 patients with large intestine tumors. There were 30 patients with colon cancer aged 78.0+/-1.1 years and 14 patients with rectal neoplasms aged 75.0+/-1.8 years. All of them underwent elective video-assisted resections without conversion of the approach. RESULTS: Good and satisfactory results were achieved in 95.5% of patients. Postoperative complications occurred in 5 (11.4%) cases followed by redo surgery in 2 (4.5%) patients. Mortality was absent. CONCLUSION: Video-assisted procedures are preferable in elective surgery of colorectal cancer in advanced age patients regardless stage and localization of the process. PMID- 29460884 TI - [A new approach in the compression therapy of postoperative scars]. AB - : The aim of the study was to evaluate the effectiveness of compression therapy with a prolonged plaster of Contractubex in the formation of skin scarring in children after surgery. MATERIAL AND METHODS: In a prospective open-label randomized trial, 109 patients aged 5.3+/-2.1 years after surgery: boys - 73, girls - 36. Patients were divided into 2 groups: in the main group (54 children) the application of the prolonged plaster Contractubex was performed; in the control group (55 patients) - dynamic observation. The scar deformation was assessed according to the Vancouver scale for 10, 30 and 90 postoperative days. RESULTS: 94.4% patients had good compliance; in 2 (3.7%) - satisfactory; in 1 (1.9%) - unsatisfactory compliance. In our study, the formation of hypertrophic scars in the main group was significantly less frequent than in the control group (1 and 8 patients, respectively, chi2=4.241, p=0.042). CONCLUSION: Thus, the use of the prolonged plaster Contractubex in the near and distant period a good cosmetic and functional result in the formation of a postoperative scar was provided.

MATERIAL AND METHODS: For the period 1985 2010 diagnostic laparoscopy was performed in 5548 patients with suspected acute appendicitis. Acute phlegmonous or gangrenous appendicitis was observed in 2275 (41.0%) patients who underwent laparoscopic appendectomy. Other acute diseases occurred in 2458 (44.3%) patients. Acute catarrhal appendicitis or secondary inflammation of the appendix were diagnosed in 815 (14.7%) patients; they did not get appendectomy. In-hospital antibacterial therapy has been administered for 1-2 days followed by discharge for outpatient treatment. One patient with acute destructive appendicitis who refused surgery was treated with antibiotics. RESULTS: Antibacterial therapy in 815 patients with acute catarrhal appendicitis allowed to avoid surgical treatment. Complications (appendicular infiltration, abscess), repeated hospitalizations within 1 month were absent. Antibacterial treatment provided recovery in 1 patient with destructive appendicitis who refused surgical treatment. CONCLUSION: Patients with acute catarrhal appendicitis diagnosed with laparoscopy do not need for appendectomy and can be cured by antibacterial therapy. PMID- 29460889 TI - [Cerebral infarctions in vertebrobasilar artery atherosclerosis]. AB - AIM: to obtain more specific information on the morphology and pathogenesis of cerebral infarctions occurring in vertebrobasilar artery (VBA) atherosclerosis. MATERIAL AND METHODS: Macro- and microscopic investigations of the brain, its arterial system, and heart were conducted in 69 autopsy cases with infarctions located in the vertebrobasilar system (VBS) in atherosclerosis. RESULTS: 69 cases were found to have 206 VBA infarctions of various extent and locations. The detected infarctions were single and multiple in 27 and 42 cases, respectively. The detected infarctions included extensive (n=7), large (n=9), medium (n=63), small deep (lacunar) (n=97), and small superficial (n=30). The brain stem showed lacunar infarctions most frequently (76% of the infarctions at this site). Medium and small infarctions were identified at the same frequency in the cerebral hemispheres and cerebellum. The occurrence of 94% of the extensive and large infarctions was ascertained to be pathogenetically associated with atherothrombotic occlusion of the intracranial arteries in the VBS. 76% of the small infarctions occurred through the mechanism of cerebral vascular insufficiency in tandem atherostenosis of VBAs in conjunction with an additional decrease in cerebral blood flow under the influence of an extracerebral factor (coronary heart disease). Medium infarctions were approximately equifrequently due to the two aforementioned causes and, in some cases, to cardiogenic thromboembolism of VBAs. Infarctions were multiple in most cases; while recent large atherothrombotic infarctions were frequently concurrent with small organized infarctions resulting from tandem atherostenosis of VBAs. CONCLUSION: This investigation could establish the relationship between the site, extent, and pathogenetic factors of infarctions in the VBA bed in atherosclerosis, as well as the prognostic value of small infarctions as predictors for severe ischemic stroke. PMID- 29460890 TI - [Increased myocardial expression of Toll-like receptors 2 and 9 as a marker of active myocarditis and a possible predictor of therapeutic effectiveness]. AB - AIM: to investigate the myocardial expression of some structural proteins and markers of cellular proliferation and innate immunity for assessing their possible diagnostic and prognostic role in patients with chronic myocarditis. SUBJECTS AND METHODS: The investigation enrolled 23 patients (16 men; mean age, 52.0+/-12.4 years (range, 27 to 73) with various forms of noncoronarogenic myocardial injury who underwent right ventricular endomyocardial biopsy (n=4), intraoperative left ventricular biopsy (n=17) or autopsy (n=2). Prior to their morphological examination, the patients were divided into two groups: 1) 10 patients with dilated cardiomyopathy and presumptive myocarditis; 2) 13 patients with valvular heart disease, hypertrophic cardiomyopathy, myxoma, and chronic pulmonary thromboembolism, presumptively without myocarditis. Along with myocardial histological and immunohistochemical (IHC) examinations, the expression of vimentin, desmin, c-kit, Ki-67, and Toll-like receptors (TLR) 2 and 9 was determined. Polymerase chain reaction was used to identify whether herpes viruses of and parvovirus B19 genomes were present in the blood and myocardial samples; indirect ELISA was applied to estimate the blood level of antibodies against various cardiac antigens. RESULTS: According to the histological findings, active/borderline lymphocytic myocarditis was diagnosed in all the patients (Group 1) and in 6 patients (Group 2) in conjunction with the underlying disease (only in 9 and 7 patients, respectively), viral genome was detected in the myocardium of 15 patients, including in 5 without morphological signs of myocarditis (parvovirus B19 (n=11), herpesvirus 6 (n=4), herpes simplex virus types 1 and 2 (n=1), Epstein-Barr virus (n=2), and cytomegalovirus (n=1)), and in the blood (n=4). A marked correlation was found between TLR2 and TLR9 expressions and the morphological pattern of active myocarditis in the absence of this correlation with the expression level of other studied markers. The expression level of TLR2 in patients with and without borderline myocarditis was 0 [0; 0,75] and in those with active myocarditis was 1.5 [1; 1,5] points; that of TLR9 was 2 [2; 2] and 4 [3; 4] points, respectively (p<0.001). The expression of TLR2 and TLR9 in patients with borderline myocarditis was lower than in those without myocarditis (0 [0; 0] versus 0 [0; 1] and 2 [1,5; 2] versus 2 [2; 3] points), which can reflect cardiomyocyte destruction/depletion at later stages of the disease. There was also a close correlation between the expression level of TLR2 and that of TLR9 (r=0.824; p<0.001) and with Ki-67 levels (r=-0.531 and r=-0.702; p<0.01). There was also a correlation of the expression of the studied markers with viral persistence (desmin), the degree of myocardial dysfunction and cardiosclerosis (c-kit), which calls for further investigations. CONCLUSION: Determination of the myocardial expression level of TLR2 and TLR9 may serve as an immunohistochemical marker for myocarditis and preservation of its activity, which is especially valuable in patients with borderline forms. The marked expression of these markers for innate immunity may reflect both one of the mechanisms of genetic predisposition to myocarditis and its severe course and their secondary activation in the pathogenesis of the disease and is a potential target of therapy.

AB - AIM: to investigate the proliferative activity and distribution of pluripotent stem cells in various histological types of amelobrastoma. MATERIAL AND METHODS: The surgical and archival materials of 76 patients with ameloblastoma from the Central Research Institute of Dentistry and Oral Surgery, Ministry of Health of the Russian Federation, were used. Tissue antigens were determined using a rabbit monoclonal antibody against to Ki-67 and SOX2. RESULTS: Proliferating (Ki-67) and pluripotent (SOX2) cells were identified in various histological types of ameloblastoma. A weak significant correlation was found between tumor size, pluripotent stem cells, and cellular proliferative activity. Enhanced cell proliferative activity and extensive bone tissue destruction significantly correlated with the development of recurrent ameloblastoma. CONCLUSION: The presence of pluripotent stem cells, the proliferative activity of ameloblastoma cells, and the extensiveness of bone tissue destruction allow basal-cell and plexiform options to be considered as the most aggressive indicators.

AB - AIM: the evaluation of Ki-67 and CD44 expression in the 'serrated' polyps of the colon and comparison them with adenocarcinomas and tubular and tubule-villous adenomas of the colon. MATERIAL AND METHODS: The study is including 49 'serrated' polyps, 34 tubular (AT) and tubulo-villous (ATV) adenomas and 32 adenocarcinomas of the colon. Antibodies CD44 and Ki-67 were used as immunohistochemical markers in this study. RESULTS: A statistically significant difference (p<0.01) was observed between traditional serrated adenomas (TSA) from hyperplastic polyps (HP) and sessile serrated adenomas (SSA) in the Ki-67 level and the localization of the Ki-67 and CD44 reaction: surface areas of the crypts (upper third) in TSA and base of crypts (lower third) in HP and SSA. There was no difference between HP and SSA (p>0.05), neither by marker localization, nor by their level. In all 'serrated' polyps of the colon, the Ki-67 reaction was nuclear; CD44 - membrane (except for 1 TSA). CONCLUSION: we are the first ones who suggested to evaluate not the overall level of reactions of CD44 and Ki-67, but particular level for each third part of crypts. The similarities of TSA, AT and ATV and between HP and SSA are shown as well as the principal statistical difference between these two groups. The cytoplasmic reaction of CD44 in adenocarcinomas and the membrane reaction of CD44 in 98% of the 'serrated' polyps of the colon are described. For the first time coexpression of CD44 and Ki-67 on particulate thirds of crypts in neoplasms of the colon is shown and the potential reasons for this phenomenon are discussed.

AB - AIM: To analyze the clinical and social outcomes of organic mental disorders (OMD), diagnosed in children and teens; establish the factors that are relevant for the formation of the clinical picture of OMD in different sexes; the circumstances that determine the dynamics of remote OMD and the level of social adaptation of patients in adulthood. MATERIAL AND METHODS: Four hundred and ninety-eight children with organic mental disorders were followed-up in one of neuropsychiatric outpatient clinics of Moscow, until they reached 23-25 years of age. The total duration of observation was from 7.5 to 22 years (M+/-sigma: 17.3+/-3.5 years). Clinical-psychopathological and follow-up methods were used. To assess social functioning of patients, a form for recording social skills of adolescents and a questionnaire for assessment of social functioning and quality of life were used. RESULTS AND CONCLUSION: In 82% of patients, OMD reduced by the time of adulthood. Disorders with severe intellectual impairment, paroxysmal disorders, psychopathic syndrome, mixed forms of the disease were the causes of a lifelong disability in 3.6% of cases.

AB - AIM: To study the parameters of vestibular evoked myogenic potentials (VEMPs) in different types of vertigo. MATERIAL AND METHODS: Seventy-seven patients, 35 men and 42 women, aged 43.7+/-12.5 years, with vestibular vertigo and unsteadiness were examined. The activity of the stemocleidomastoid muscle in response to auditory stimulation of the ipsilateral ear was recorded using surface electromyography. RESULTS: There were a trend towards the increase in the N2 latency, the significant reduction of the P1-N2 amplitude (p<0,005) on both sides and significant changes in the coefficient of asymmetry. Compared to healthy people, the P1 latency and asymmetry in P1 latency were significantly increased in patients with peripheral type of vertigo (p<0,005 and r=0,0007, respectively). There were no differences in the P1 latency and N2 in patients with unsteadiness. CONCLUSION: In patients with peripheral vertigo, central vertigo and unsteadiness, vestibular-spinal reflex was disturbed at different levels of vestibular analyzer. PMID- 29460900 TI - [The study of the membrane-protective potential of the combination of 2-ethyl-6 methyl-3-hydroxypyridine-succinate and citicoline]. AB - AIM: To assess the changes in the composition of plasma phospholipids in patients with chronic cerebrovascular disease treated with neuroprotectors 2-ethyl-6 methyl-3-hydroxypyridine succinate (neurox) and citicoline (neipilept), the natural metabolites involved in biochemical processes in the body, and their composition. MATERIAL AND METHODS: The study included 40 patients, 18 men and 22 women, aged from 54 to 72 years, with chronic cerebrovascular disease at the decompensation stage complicated with the hypertensive crisis and/or arrhythmia. RESULTS AND CONCLUSION: During extraction of phospholipids from blood cells, a significant decrease in the amount of total lipids was found to the end of treatment of patients who received neurox or neipilept or their combination. The study of quantitative composition of phospholipids showed no significant changes in patients treated with neurox, while the use of citicoline or combination of citicoline with 2-ethyl-6-methyl-3-hydroxypyridine succinate resulted in the increase of their total mass. There were no significant changes in the qualitative composition of phospholipid classes in blood plasma in patients treated with neurox. In patients treated with neipilept or with the combination of citicoline with 2-ethyl-6-methyl-3-hydroxypyridine succinate, plasma phosphatidylcholine was significantly increased. No significant changes in the content of phosphatidylinositol, phosphatidylserine and sphingomyelin were observed. PMID- 29460901 TI - [The clinical significance of the lamotrigine pharmacokinetic variability]. AB - AIM: To estimate pharmacokinetic variability of lamotrigine (LTG) and its clinical significance. MATERIAL AND METHODS: One hundred patients, including 74 women, aged from 18 to 77 years (38.23+/-14.37 years), with focal epilepsy were examined. Monotherapy with LTG was administered to 54 patients, duotherapy to 46 patients (LTG and valproic acid combination to 27 patients, LTG and liver enzymes inducers to 19 patients). Patients underwent procedures of therapeutic drug monitoring (TDM). Minimal (Cssmin) and maximal (Cssmax) steady-state LTG plasma concentrations, and concentration-to-weight ratio (CDR) were calculated. RESULTS AND CONCLUSION: In patients who used LTG in monotherapy, LTG Cssmin was 5.6+/ 4.65 mg/l, Cssmax 7.59+/-5.54 mg/l. In the group that received LTG in combination with valproate, LTG Sssmin was 7.8 [5.4; 11.8] mg / l and Cssmax 11.4 [7.3; 15.3] mg/l. In the group that received LTG in combination with drug-inducers of glucuronidation, Cssmin was 2.5 [1.99; 4.32] mg/l, Cssmax 4.73 [2.91; 6.70] mg/l. Statistically significant differences in CDR parameter between groups with LTG monotherapy and duotherapy, both with inducer and with inhibitors, as well as between groups of duotherapy with inductors and with inhibitors were obtained. The results of the study indicate a pronounced pharmacokinetic variability of the LTG. Conducting TDM allows the establishment of individual therapeutic concentrations of LTG in blood plasma and setting a correction vector for antiepileptic therapy.

AB - AIM: To study the dynamics of cognitive impairment in patients with chronic cerebral ischemia (CCI) treated with cortexin and memantinol (memantine). MATERIAL AND METHODS: The authors present the results of the multicenter observational program 'KORMEN' that studied the efficacy of cortexin and memantinol in the treatment of cognitive impairment in patients with CCI. The study included 495 patients, 204 (41.2%) men and 291 (58.8%) women. Patients were stratified into two groups: cortexin group (n=388 (78.4%)) and cortexin + memantinol group. RESULTS AND CONCLUSION: A significant positive effect of treatment based on the scores on 4 cognitive scales was shown in both groups of patients. The addition of memantinol significantly improved cognitive functions in patients with severe cognitive impairment (r<0.05). The safety profile of the drugs was confirmed.

AB - AIM: To study the efficacy of the complex therapy, including cocarnit (group B vitamins, triphosadenine and nicotinamide), of diabetic neuropathy. MATERIAL AND METHODS: Forty-one patients with diabetes mellitus type 2 and distal symmetric sensorimotor polyneuropathy were examined. Patients were divided into 2 groups. Patients of the main group (n=26) received complex therapy, including cocarnit, and patients of the comparison group (n=15) received standard treatment. RESULTS AND CONCLUSION: The positive dynamics based on the VAS (r=0.0001), TSS (r=0.0001), NSS (r=0.001), NDS (r=0.0431), SF-36 (r=0.0008), electroneuromyographic results and glycated hemoglobin levels was observed in the main group. In patients of the comparison group, the positive dynamics was instable; the scores of clinical scales did not reach statistical significance. The results suggest the use of cocarnit in the complex treatment of patients with diabetic neuropathy. PMID- 29460904 TI - [Syndrome of autonomic dysfunction in children and adolescents]. AB - AIM: To study clinical and pathophysiological symptoms of autonomic dysfunction syndrome in children and adolescents and assess the efficacy of its treatment with nooclerin. MATERIAL AND METHODS: Fifty-three patients, aged from 10 to 15 years, with autonomic dysfunction syndrome were examined. All patients underwent neurological examination, assessment with the A.M. Vein's questionnaire of autonomic disorders, the 10 point Visual Analogous scale for headache and fatigue, the Spielberger-Khanin scale for anxiety, Kerdo index, Hildebrandt's coefficient, electrocardiography with clinoorthostatic test, electroencephalography, and TOVA psychophysiological test. RESULTS AND CONCLUSION: The signs of the asthenic-autonomic syndrome were characteristic of the clinical picture of disease. EEG results demonstrated the deficit of activation effects, predominance of synchronized effects of thalamic structures which led to the insufficient activation of cortical structures. These data support the high efficacy of nooclerin. PMID- 29460905 TI - [Multi-centre clinical assessment of the Russian language version of the Diagnostic Interview for Psychoses]. AB - OBJECTIVES: The Diagnostic Interview for Psychoses (DIP) was developed to enhance the quality of diagnostic assessment of psychotic disorders. The aim of the study was the adaptation of the Russian language version and evaluation of its validity and reliability. MATERIAL AND METHODS: Ninety-eight patients with psychotic disorders (89 video recordings) were assessed by 12 interviewers using the Russian version of DIP at 7 clinical sites (in 6 cities of the Russian Federation). DIP ratings on 32 cases of a randomized case sample were made by 9 interviewers and the inter-rater reliability was compared with the researchers' DIP ratings. Overall pairwise agreement and Cohen's kappa were calculated. Diagnostic validity was evaluated on the basis of comparing the researchers' ratings using the Russian version of DIP with the 'gold standard' ratings of the same 62 clinical cases from the Western Australia Family Study Schizophrenia (WAFSS). RESULTS: The mean duration of the interview was 47+/-21 minutes. The Kappa statistic demonstrated a significant or almost perfect level of agreement on the majority of DIP items (84.54%) and a significant agreement for the ICD-10 diagnoses generated by the DIP computer diagnostic algorithm (kappa=0.68; 95% CI 0.53,0.93). The level of agreement on the researchers' diagnoses was considerably lower (kappa=0.31; 95% CI 0.06,0.56). The agreement on affective and positive psychotic symptoms was significantly higher than agreement on negative symptoms (F(2,44)=20.72, p<0.001, eta2=0.485). The diagnostic validity of the Russian language version of DIP was confirmed by 73% (45/62) of the Russian DIP diagnoses matching the original WAFSS diagnoses. Among the mismatched diagnoses were 80 cases with a diagnosis of F20 Schizophrenia in the medical documentation compared to the researchers' F20 diagnoses in only 68 patients and in 62 of the DIP computerized diagnostic outputs. The reported level of subjective difficulties experienced when using the DIP was low to moderate. CONCLUSION: The results of the study confirm the validity and reliability of the Russian version of the DIP for evaluating psychotic disorders. DIP can be recommended for use in education and training, clinical practice and research as an important diagnostic resource. PMID- 29460906 TI - [Changes in spatial relationships between catecholamine- and nitroxidergic neurons in the nuclei of the caudal brain stem in the development of hypertension]. AB - AIM: To obtain the data on the spatial relationships between catecholamine (TH positive) and nitroxidergic (nNOS-positive) neurons in vasomotor nuclei of the medulla in different periods of hypertension development. MATERIAL AND METHODS: The experiment was performed on male Wistar rats (n=45) with induced renovascular hypertension (RVH). TH and nNOS in neurons of solitary tract nuclei, reticular small-and giant cell nuclei were detected using immunohistochemical methods. RESULTS AND CONCLUSION: The most early and severe changes in the intensity of reaction and amount of nNOS-positive neurons were noted in the solitary tract nucleus. Significant changes in the quantitative parameters of TH-positive neurons in RVH were identified only in the reticular giant cell nucleus but they appeared later and were less expressed compared to nNOS-positive cells. This resulted in the changes of spatial relationships between two types of neurons and remodeling of the bulbar region of the cardiovascular center. PMID- 29460907 TI - [Maturation of integrative sleep apparatus in children in normal and pathological condition]. AB - AIM: To study and compare clinical characteristics of sleep macrostructure and sleep cycle organization during the night polysomnographic study in children with attention deficit hyperactivity disorder (ADHD) and obstructive sleep apnea syndrome (OSAS) aged from 6 to 9 years. MATERIAL AND METHODS: Polysomnography was performed in 40 children with ADHD and 20 children with OSAS. The control group included 20 healthy children. RESULTS AND CONCLUSION: The changes in sleep architectonics were unidirectional. Typical for the two groups of children was an increase in the latency of REM sleep and a reduction of its duration in total time of sleep. In children with ADHD, there was a significant decrease in the total number of sleep cycles, with a significant increase in the duration of the first sleep cycle. For an objective assessment of the rhythmic organization of ultradian rhythms, the authors propose a formula to calculate the maturity index of sleep in children older than 6 years. From the standpoint of evolutionary neuroscience, results should be considered as manifestations of dysontogenesis. PMID- 29460908 TI - [Association of sleep disorders with headache]. AB - AIM: The aim of the present study was to investigate the connection of sleep disorders (SD) with a headache (HA) among the representative sample of population. MATERIAL AND METHODS: 1115 inhabitants of Chuvashia (491 men and 624 women) aged from 18 to 70 years old have been interviewed (middle age 38.7+/-13.9 years old); respondents under 18 and over 70 years old were not included into the research. There were 690 city residents, and 425 residents of the rural areas. The questionnaire approved earlier in the research of HA, and also the questions directed to identification of SD were used. One-way ANOVA, Chi-square test were used to compare variables of the groups. RESULTS: There were 718 (64.4%) respondents with SD and HA (the main group), 366 (23.8%) with HA without SD (comparative group), 16 (1.4%) with SD without HA, and 15 (1.3%) without SD and HA. The main group of the respondents authentically differed from other groups in older age, a larger number of women and villagers, presence of concomitant diseases in them. In the respondents with SD arose more often, pain had the combined (polymorphic) character, HA were more severe, localized in several areas of the head, but were of smaller duration. Among them there were more people with short sleep duration (<5 hours of night dream) and accepting sedative-hypnotic medications. HA without SD had a pricking character more often; the respondents more often slept in the afternoon, differed in higher level of education, and a rarer occurrence of cases of the increased arterial pressure. CONCLUSION: SD are often connected with HA, with their frequency, expressiveness and localization. Development of SD from HA are influenced by existence of concomitant diseases, age, gender and the place a residence. SD make the current of HA more severe.

AB - Alzheimer's disease (AD) is a serious medical and social problem of our time, while remaining the most common cause of dementia in the elderly. The leading symptom in the clinical picture of the disease is a progressive loss of memory with further development of behavioral disorders. In the early stages of AD, patients are mostly managed by neurologists and differential diagnosis is carried out with a variety of neurodegenerative diseases. The authors present clinical criteria of AD diagnosis and consider diagnostic possibilities in the predementia stage using biological markers. With this purpose, modern concepts of the etiology and pathogenesis of AD and genetic aspects of pathology are considered. Contribution of many environmental factors to the initiation and progression of the disease process is evaluated. Mechanisms of cerebral amyloidosis and its characteristic neurological manifestations are considered. PMID- 29460911 TI - ['Masks' of acute neuroinfections and markers of differencial diagnosis]. AB - AIM: To compare the medical history, clinical features, composition of cerebrospinal fluid (CSF), results of laboratory and instrumental examinations of patients with acute neuroinfections and differentiable diseases including a pseudoinflammatory variant of the acute stage of uncomplicated subarachnoid hemorrhage (SAH), consequences of traumatic brain injury (traumatic SAH, SAN combination with secondary purulent meningitis, posttraumatic nasal liquorrhea, intracerebral hematomas), abscesses and tumors of the brain, lymphoma with proven CNS. These diagnoses were mistakenly made to patients admitted to an infectious department. MATERIAL AND METHODS: Forty-six patients, aged from 18 to 83 years, hospitalized in the Department of neuroinfections and intensive care in 2010-2016 were examined. Conventional clinical neurological, laboratory, instrumental (including MRI) examinations of patients, comprehensive examination of CSF samples, the study of markers of inflammation (C - reactive protein, CSF lactate), immunophenotyping of CSF cells were performed. RESULTS AND CONCLUSION: The misdiagnosis can be explained by the overestimation of such symptoms as the acute (in most cases) onset of the disease with increased body temperature to febrile levels, presence of meningeal syndrome, disorders of consciousness and focal symptoms of varying severity. The authors showed the errors and difficulties in the diagnosis, the role and importance of an integrated, interdisciplinary approach taking into account history, clinical data, results of CSF study, conventional and special methods of laboratory and instrumental examination of patients.

On the one hand, some diseases can produce symptoms similar to migraine (cerebral aneurysm before rupture, reversible cerebral vasoconstriction syndrome). On the other hand, migraine with aura and some other disorders are conditions that have common pathophysiological mechanisms (e.g., CADASIL and MELAS syndrome, antiphospholipid syndrome). Thirdly, clinical presentations of migraine are often difficult to distinguish from features of other headache conditions (migraine with aura - transient ischemic attack, migraine with visual aura - occipital epilepsy). The author discusses the differential diagnosis of acute headache, especially thunderclap headache, and main strategies of effective treatment of migraine attacks.

PMID- 29460915 TI - [Nutritional support to patients with severe blood circulation disorders]. AB - Eating disorders in stroke patients are always accompanied by structural and functional changes in the body, which leads to violations of adaptive reserves and trophic homeostasis. It is known that trophic homeostasis, together with optimal oxygen supply, forms the basis of the vital activity of the organism and is a necessary condition for overcoming of many pathological conditions. Insufficient nutrition leads to a slower recovery of patients, increases the risk of complications, predicts prolonged hospital stay, increases mortality. Inability of adequate feeding causes the necessity of obligatory administration of nutritional support to patients in a severe condition. The article provides a review of the main principles of organization of nutritional support in stroke patients and ways to assess its effectiveness.

PMID- 29460918 TI - Treatment of supragastric belching with cognitive behavioral therapy improves quality of life and reduces acid gastroesophageal reflux. AB - OBJECTIVES: Excessive supragastric belching (SGB) manifests as troublesome belching, and can be associated with reflux and significant impact on quality of life (QOL). In some GERD patients, SGB-associated reflux contributes to up to 1/3 of the total esophageal acid exposure. We hypothesized that a cognitive behavioral intervention (CBT) might reduce SGB, improve QOL, and reduce acid gastroesophageal reflux (GOR). We aimed to assess the effectiveness of CBT in patients with pathological SGB. METHODS: Patients with SGB were recruited at the Royal London Hospital. Patients attended CBT sessions focused on recognition of warning signals and preventative exercises. Objective outcomes were the number of SGBs, esophageal acid exposure time (AET), and proportion of AET related to SGBs. Subjective evaluation was by patient-reported questionnaires. RESULTS: Of 51 patients who started treatment, 39 completed the protocol, of whom 31 had a follow-up MII-pH study. The mean number of SGBs decreased significantly after CBT (before: 116 (47-323) vs. after 45 (22-139), P<0.0003). Sixteen of 31 patients were shown to have a reduction in SGB by >50%. In patients with increased AET at baseline, AET after CBT was decreased: 9.0-6.1% (P=0.005). Mean visual analog scale severity scores decreased after CBT (before: 260 (210-320) mm vs. after: 140 (80-210) mm, P<0.0001). CONCLUSIONS: Cognitive behavioral therapy reduced the number of SGB and improved social and daily activities. Careful analysis of MII pH allows identification of a subgroup of GERD patients with acid reflux predominantly driven by SGB. In these patients, CBT can reduce esophageal acid exposure.

PMID- 29460921 TI - Measuring Change In Small Intestinal Histology In Patients With Celiac Disease. AB - Small intestinal histologic abnormalities in celiac disease include atrophy of the intestinal villi, hypertrophy of the crypts and lymphocytic infiltration of intraepithelial spaces and lamina propria. These findings are central to diagnosis and their severity and change over time are valuable to monitor disease course and response to therapy. Subjective methods to grade celiac disease histological severity include the Marsh-Oberhuber and Corazza-Villanacci systems. Quantitative histology uses villus height (Vh), crypt depth (Cd), and intra epithelial lymphocyte count (per 100 enterocytes) to provide objective measures of histologic changes including Vh:Cd ratio. Here we examine the available literature regarding these methodologies and support the use of quantitative histology as the preferred method for accurately and reproducibly demonstrating change of relevant histologic end points over time. We also propose a Quantitative-Mucosal Algorithmic Rules for Scoring Histology (Q-MARSH) system to partially align quantitative histology results with the traditional Marsh, Marsh Oberhuber, and Corazza-Villanacci systems. Q-MARSH can provide a standardized, objective, and quantitative histology scoring system for use as a clinical or research application. PMID- 29460920 TI - Long-Term Safety of In Utero Exposure to Anti-TNFalpha Drugs for the Treatment of Inflammatory Bowel Disease: Results from the Multicenter European TEDDY Study. AB - OBJECTIVES: The long-term safety of exposure to anti-tumor necrosis factor (anti TNFalpha) drugs during pregnancy has received little attention. We aimed to compare the relative risk of severe infections in children of mothers with inflammatory bowel disease (IBD) who were exposed to anti-TNFalpha drugs in utero with that of children who were not exposed to the drugs. METHODS: Retrospective multicenter cohort study. Exposed cohort: children from mothers with IBD receiving anti-TNFalpha medication (with or without thiopurines) at any time during pregnancy or during the 3 months before conception. Non-exposed cohort: children from mothers with IBD not treated with anti-TNFalpha agents or thiopurines at any time during pregnancy or the 3 months before conception. The cumulative incidence of severe infections after birth was estimated using Kaplan Meier curves, which were compared using the log-rank test. Cox-regression analysis was performed to identify potential predictive factors for severe infections in the offspring. RESULTS: The study population comprised 841 children, of whom 388 (46%) had been exposed to anti-TNFalpha agents. Median follow-up after delivery was 47 months in the exposed group and 68 months in the non-exposed group. Both univariate and multivariate analysis showed the incidence rate of severe infections to be similar in non-exposed and exposed children (1.6% vs. 2.8% per person-year, hazard ratio 1.2 (95% confidence interval 0.8-1.8)). In the multivariate analysis, preterm delivery was the only variable associated with a higher risk of severe infection (2.5% (1.5-4.3)). CONCLUSIONS: In utero exposure to anti-TNFalpha drugs does not seem to be associated with increased short-term or long-term risk of severe infections in children.

AB - The success of next-generation androgen receptor (AR) pathway inhibitors, such as abiraterone acetate and enzalutamide, in treating prostate cancer has been hampered by the emergence of drug resistance. This acquired drug resistance is driven, in part, by the ability of prostate cancer cells to change their phenotype to adopt AR-independent pathways for growth and survival. Around one quarter of resistant prostate tumours comprise cells that have undergone cellular reprogramming to become AR-independent and to acquire a continuum of neuroendocrine characteristics. These highly aggressive and lethal tumours, termed neuroendocrine prostate cancer (NEPC), exhibit reactivation of developmental programmes that are associated with epithelial-mesenchymal plasticity and acquisition of stem-like cell properties. In the past few years, our understanding of the link between lineage plasticity and an emergent NEPC phenotype has considerably increased. This new knowledge can contribute to novel therapeutic modalities that are likely to improve the treatment and clinical management of aggressive prostate cancer.

PMID- 29460927 TI - Semiautomatic determination of arterial input function in DCE-MRI of the abdomen. AB - The goal of this study was to develop a semiautomatic segmentation technique of the abdominal aorta to determine the arterial input function (AIF). A total of 24 patients having therapy naive abdominal cancers were imaged using DCE-MRI on a 3T MR scanner. DCE-MRI continued for 4.2 minutes with 2.1 seconds temporal resolution (120 acquisitions). Gadoteridol (0.1 mmol/kg) was infused intravenously at 30 seconds after starting DCE-MRI, and flushed with 20-ml saline (2 ml/s). Patients were instructed to hold breath after maximal inhalation, and repeat as needed to full inspiration. The location of the abdominal aorta was manually identified, but its segmentation and motion tracking were automatically implemented. AIFs determined in the aortic region with and without tracking motion were statistically compared. The aortic region was further segmented into multiple smaller regions, and the AIF change according to the size of the region of interest (ROI) was examined. The displacement of the abdominal aorta during DCE-MRI was 3.4+/-2.3 (mean+/-SD) mm. The root mean square error (RMSE) of AIF from the best fitting curve was 0.110+/-0.010 mM after motion correction, which was significantly smaller than that before motion correction (0.134+/-0.016 mM; p<0.001). The amplitude of AIF varied up to 15% according to the ROI size. However, when the radius of ROI was reduced more than 3 mm, the variation in AIF amplitude was less than 5%. Therefore the ROI having smaller radius than that of aorta will need to be used to determine a reliable AIF in abdominal DCE-MRI.

AB - Inspired by nature, collagen is an outstanding polypeptide utilized to exploit its bioactivity and material design for healthcare technologies. In this study, we describe the self-aggregation of water-dispersible nanocollagen helices upon solidification to fabricate different forms of natural collagen materials. Chemically extracted native collagen fibrils are uniform anisotropic nanoparticles with an average diameter of about 50 nm and a high aspect ratio. The as-prepared collagen nanofibrils are soluble in sodium acetate-acetic acid buffer and are dispersible in water, thus generating collagen liquids that are used as distinct biopolymer precursors for materials development. Our interesting findings indicate that water-dispersible collagen-derived alcogels undergo critical point drying to self-arrange hierarchical nanofibrils into helix bundles in collagen sponge-like aerogels. Notably, using lyophilization to remove water in the biopolymer dispersion, a full regeneration of solidified fibers is achieved, producing collagen aerogels with lightweight characteristics similar to natural cottons. The self-aggregation of water-dispersible collagen occurs under freeze-drying conditions to turn individual nanofibrils into sheets with layered structures in the aerogel networks. The development of transparent, water resistant collagen bioplastic-like membranes was achieved by supramolecular self assembly of water-dispersible collagen nanofibrils. Our efforts present a reliable concept in soft matter for creating promising collagen examples of liquids, hydrogels, aerogels, and membranes to increase utilization value of native collagen for biomedicine, pharmaceuticals, cosmetics, and nutrients. PMID- 29460925 TI - Clinical implications of PTEN loss in prostate cancer. AB - Genomic aberrations of the PTEN tumour suppressor gene are among the most common in prostate cancer. Inactivation of PTEN by deletion or mutation is identified in ~20% of primary prostate tumour samples at radical prostatectomy and in as many as 50% of castration-resistant tumours. Loss of phosphatase and tensin homologue (PTEN) function leads to activation of the PI3K-AKT (phosphoinositide 3-kinase RAC-alpha serine/threonine-protein kinase) pathway and is strongly associated with adverse oncological outcomes, making PTEN a potentially useful genomic marker to distinguish indolent from aggressive disease in patients with clinically localized tumours. At the other end of the disease spectrum, therapeutic compounds targeting nodes in the PI3K-AKT-mTOR (mechanistic target of rapamycin) signalling pathway are being tested in clinical trials for patients with metastatic castration-resistant prostate cancer. Knowledge of PTEN status might be helpful to identify patients who are more likely to benefit from these therapies. To enable the use of PTEN status as a prognostic and predictive biomarker, analytically validated assays have been developed for reliable and reproducible detection of PTEN loss in tumour tissue and in blood liquid biopsies. The use of clinical-grade assays in tumour tissue has shown a robust correlation between loss of PTEN and its protein as well as a strong association between PTEN loss and adverse pathological features and oncological outcomes. In advanced disease, assessing PTEN status in liquid biopsies shows promise in predicting response to targeted therapy. Finally, studies have shown that PTEN might have additional functions that are independent of the PI3K-AKT pathway, including those affecting tumour growth through modulation of the immune response and tumour microenvironment. PMID- 29460929 TI - Practical immune-barometer sensor for trivalent chromium ion detection using gold core platinum shell nanoparticle probes. AB - The technology progress of biosensors has markedly improved healthcare, disease diagnosis, environment monitoring, and food safety control over the past few decades. However, development of sensitive, robust, low-cost and portable assays for on-site bioanalysis is still a great challenge. In this study, we described a portable, feasible and miniaturized immune-barometer sensor (IBS), which can be used to sensitively measure the changes in a pressure signal, and we applied this IBS in the detection of Cr(iii). In this system, a competitive immunoassay was incorporated as a signaling technique for Cr(iii) detection. To generate a signal of pressure changes (DeltaP), Au@PtNPs (gold core platinum shell nanoparticles) were prepared for decomposing H2O2 to generate O2 in a sealed chamber. The expansion of gas volume was accurately detected using a sensitive barometer in the sealed reaction chamber. The DeltaP correlated well with Cr(iii) concentrations ranging from 0.39 to 25 ng mL-1. The limit of detection (LOD) of the IBS was estimated to be as low as 0.35 ng mL-1. Furthermore, the IBS has high specificity and high recovery for Cr(iii) detection in tap water samples (97.5% 108.7%) and in the Pearl River water samples (95.6%-110.2%). Compared with the traditional enzyme-linked immunosorbent assay (ELISA), the IBS was observed to be more sensitive, of low-cost and portable for the on-site detection of Cr(iii). Therefore, the IBS is a promising potential method for the detection of heavy metals in aqueous solutions and many other fields. PMID- 29460930 TI - Transport and accumulation of plasma generated species in aqueous solution. AB - The interaction between cold atmospheric pressure plasma and liquids is receiving increasing attention for various applications. In particular, the use of plasma treated liquids (PTL) for biomedical applications is of growing importance, in particular for sterilization and cancer treatment. However, insight into the underlying mechanisms of plasma-liquid interactions is still scarce. Here, we present a 2D fluid dynamics model for the interaction between a plasma jet and liquid water. Our results indicate that the formed reactive species originate from either the gas phase (with further solvation) or are formed at the liquid interface. A clear increase in the aqueous density of H2O2, HNO2/NO2- and NO3- is observed as a function of time, while the densities of O3, HO2/O2- and ONOOH/ONOO are found to quickly reach a maximum due to chemical reactions in solution. The trends observed in our model correlate well with experimental observations from the literature. PMID- 29460931 TI - Nanocatalysts for hydrogen evolution reactions. AB - Hydrogen fuel is among the cleanest renewable resources and is the best alternative to fossil fuels for the future. Hydrogen can be best produced by means of electrolysis or photoelectrolysis of water among the various routes available for hydrogen production. So far, Pt has been recognized as the best electrode material for electrochemical hydrogen production. However, the cost of the catalyst, activity, and durability make Pt-catalyzed hydrogen production unsuitable on a commercial scale. It has hence become imperative to explore low cost, highly active and durable HER catalysts to replace platinum as a catalyst. This perspective provides key concepts and the current status of the research on the properties of nanocatalysts that influence the hydrogen evolution reaction. Important structural features controlling the surface chemistry (i.e. facets, defects, dopants), nature of supports (graphene, CNTs, black phosphorus), role of heteroatoms, media and morphology are the key points of discussion in this perspective. PMID- 29460932 TI - Site-specific binding of a water molecule to the sulfa drugs sulfamethoxazole and sulfisoxazole: a laser-desorption isomer-specific UV and IR study. AB - To determine the preferred water molecule binding sites of the polybasic sulfa drugs sulfamethoxazole (SMX) and sulfisoxazole (SIX), we have studied their monomers and monohydrated complexes through laser-desorption conformer-specific UV and IR spectroscopy. Both the SMX and SIX monomer adopt a single conformer in the molecular beam. On the basis of their conformer-specific IR spectra in the NH stretch region, these conformers were assigned to the SMX and SIX global minimum structures, both exhibiting a staggered sulfonamide group and an intramolecular C HO[double bond, length as m-dash]S hydrogen bond. The SMX-H2O and SIX-H2O complexes each adopt a single isomer in the molecular beam. Their isomeric structures were determined based on their isomer-specific IR spectra in the NH/OH stretch region. Quantum Theory of Atoms in Molecules analysis of the calculated electron densities revealed that in the SMX-H2O complex the water molecule donates an O-HN hydrogen bond to the heterocycle nitrogen atom and accepts an N HO hydrogen bond from the sulfonamide NH group. In the SIX-H2O complex, however, the water molecule does not bind to the heterocycle but instead donates an O HO[double bond, length as m-dash]S hydrogen bond to the sulfonamide group and accepts an N-HO hydrogen bond from the sulfonamide NH group. Both water complexes are additionally stabilized by a Cph-HOH2 hydrogen bond. Interacting Quantum Atoms analysis suggests that all intermolecular hydrogen bonds are dominated by the short-range exchange-correlation contribution.

AB - Due to increasing interest in the development of advanced nanomaterials from nanosheets as building blocks, methods for the preparation of nanosheet materials and their hybrids have been studied carefully and extensively. In this review, studies of mechanochemical methods (solid-solid reactions under ambient conditions or solvent-free synthesis) for the preparation of intercalation compounds are summarized. Mechanochemical reactions without using solvent have operational advantages, such as their environmentally benign nature and the fact that separating and drying the products is not necessary. In addition to their advantages from green chemistry viewpoints, solid-state reactions have potential for the preparation of novel intercalation compounds which are not accessible by conventional solution-based methods.

AB - A novel C16 tetranorditerpenoid, norcrassin A (1), and an unusual dimeric labdane type diterpenoid, bicrotonol A (2), were isolated from the roots of Croton crassifolius. Norcrassin A (1) featured a new carbon skeleton with an unprecedented 5/5/5/6 tetracyclic system. Bicrotonol A (2) possessed an unusual tetrahydroxypyran ring linkage connecting two labdane diterpenoid monomers. The structures of all compounds, including the absolute configuration, were elucidated by the interpretation of their NMR spectroscopic data, high resolution mass spectrometry, and single-crystal X-ray diffraction. A plausible biosynthetic pathway of 1 is proposed. The anti-Alzheimer's Disease (AD) activities of 1 and 2 are also evaluated using the AD pathological model.

AB - Selective carbon dioxide photoreduction to produce formic acid was achieved under visible light irradiation using water molecules as electron donors, similar to natural plants, based on the construction of a Z-scheme light harvesting system modified with a Cu-Zn alloy nanoparticle co-catalyst. The faradaic efficiency of our Z-scheme system for HCOOH generation was over 50% under visible light irradiation. PMID- 29460938 TI - Spin-encoded subwavelength all-optical logic gates based on single-element optical slot nanoantennas. AB - Optical logic gates are important elements in optical computing and optical circuits. However, the footprints of the present optical logic gates are still on the micrometer scale. Further miniaturization of the logic gates to nanometer scale remains challenging. Here we propose, and demonstrate experimentally, subwavelength all-optical logic gates based on single-element optical slot nanoantennas. By employing a spin-encoded scheme, we achieve OR, AND, NOT, NAND and NOR logic gates via an L-shaped optical slot nanoantenna with a footprint of 300 nm by 300 nm, and a XNOR logic gate via a rectangle optical slot nanoantenna with a footprint of 220 nm by 60 nm. The SPP launching and logic operation via mode coupling instead of path interference are integrated together at a single element nanoantenna, which considerably shrinks the dimensions of the device. The experimental results show the potential of the single optical slot nanoantenna in subwavelength all-optical logic computing and nanophotonic information processing.

AB - A novel cucurbit[6]uril-based (Q[6]) supramolecular assembly {(NH4)2.Q[6].(HDTNB)2.2H2O} (1) with a three-dimensional (3D) framework structure was successfully constructed via outer-surface interactions between Q[6] and a flexible aromatic compound, 5,5'-dithiobis-(2-nitrobenzoic acid) (H2DTNB), as a structure-directing agent. It is interesting to find that assembly 1 can selectively capture Ba(ii) cations among the common alkaline-earth metal ions of Mg(ii), Ca(ii), Sr(ii) and Ba(ii), resulting in the formation of an isomorphic 3D assembly {Ba(H2O)2Q[6]}.(HDTNB)2 (2). Furthermore, both assemblies 1 and 2 exhibit the selective sensing of Fe(iii) ions through fluorescence quenching, which has rarely been reported for Q[n]-based supramolecular assemblies. PMID- 29460940 TI - Copper-mediated domino C-H iodination and nitration of indoles. AB - An efficient and cost-effective copper-mediated aerobic oxidative C-H iodination and nitration of indoles via double C-H functionalization is reported. The domino process proceeds smoothly under mild aerobic conditions to give 3-iodo-2 nitroindoles in one step with high regioselectivity and a broad substrate scope. The mechanism of the iodination step is proposed to proceed via a Cu(iii)-iodide species that undergoes electrophilic addition at the C3 position of the indole motif. The subsequent nitration step involves a sequence of C-H activation, nitro radical oxidative addition, and reductive elimination. PMID- 29460941 TI - Water-soluble platinum nanoparticles stabilized by sulfonated N-heterocyclic carbenes: influence of the synthetic approach. AB - The synthesis of metal nanoparticles (NPs) under controlled conditions in water remains a challenge in nanochemistry. Two different approaches to obtain platinum NPs, which involve the treatment of aqueous solutions of preformed sulfonated (NHC)Pt(ii) dimethyl complexes with carbon monoxide, and of (NHC)Pt(0) diolefin complexes with dihydrogen (NHC = N-heterocyclic carbene), are disclosed here. The resulting NPs were found to be highly stable in water under air for an indefinite time period. Coordination of the NHC ligands to the platinum surface via the carbenic carbon was monitored by solid-state NMR spectroscopy, and the presence of a platinum-carbon bond was unambiguously evidenced by the determination of a 13C-195Pt coupling constant (1106 and 1050 Hz for NPs containing 13C labeled-NHC ligands and prepared under CO and H2, respectively). The coordination of CO to the (NHC)Pt(ii) precursors prior to formation of the NPs was confirmed by NMR spectroscopy. When using a disulfonated NHC ligand, a second coordination sphere containing bis(NHC)Pt(ii) complexes is described. Under CO, the formation of NPs was found to be slower than in a previously reported thermal method (Angew. Chem., Int. Ed., 2014, 53, 13220-13224), but led to NPs of similar sizes, whereas under H2, the synthesis of platinum NPs progressed even more slowly and produced larger NPs. In addition to the influence of the synthetic approach, the present study highlights the importance of ligand design for NP stabilization.

AB - As a fascinating conjugated polymer, graphitic carbon nitride (g-C3N4) has attracted much attention for solving the worldwide energy shortage and environmental pollution. In this work, for the first time we report oxygen self doping of solvothermally synthesized g-C3N4 nanospheres with tunable electronic band structure via ambient air exposure for unprecedentedly enhanced photocatalytic performance. Various measurements, such as XPS, Mott-Schottky plots, and density functional theory (DFT) calculations reveal that such oxygen doping can tune the intrinsic electronic state and band structure of g-C3N4via the formation of C-O-C bond. Our results show that the oxygen doping content can be controlled by the copolymerization of the precursors. As a consequence, the oxygen doped g-C3N4 shows excellent photocatalytic performance, with an RhB photodegradation rate of 0.249 min-1 and a hydrogen evolution rate of 3174 MUmol h-1 g-1, >35 times and ~4 times higher than that of conventional thermally made pure g-C3N4 (0.007 min-1 and 846 MUmol h-1 g-1, respectively) under visible light. Our work introduces a new route for the rational design and fabrication of doping modified g-C3N4 photocatalyst for efficient degradation of organic pollutants and H2 production. PMID- 29460946 TI - Lattice self-consistent field calculations of ring polymer brushes. AB - We reported the first systematic study using lattice self-consistent field (LSCF) calculations of ring homopolymer brushes grafted onto a flat and homogeneous surface and immersed in an explicit and athermal solvent, which are either uncompressed, compressed by a flat and impenetrable surface, or compressed by an identical brush. Our results clearly show that ring brushes are slightly less stretched than, thus nearly but not completely identical to, the "equivalent" linear brushes having half the chain length and double the grafting density. Our LSCF results are consistent with the molecular simulation results reported in the literature (Reith et al., Europhys. Lett., 2011, 95, 28003; Erbas and Paturej, Soft Matter, 2015, 11, 3139), except that Erbas and Paturej reported that the normal pressure of two opposing ring brushes is only half of the "equivalent" linear brushes at melt density.

AB - pseudo[1]Catenane 3 is in a self-included conformation in chloroform, but in dichloromethane, it exists in an equilibrium between the self-included conformational state and a de-threading one. The planar chirality inversion of 3 can be triggered by the host-guest complexation of 3 with adiponitrile G, but the extent of such chiral switching depends on the length of self-included bis(pyrazin-2-yloxy)alkane chains in 3 - longer chains are more favored than shorter ones in the inversion. PMID- 29460949 TI - An on-chip hybrid plasmonic light steering concentrator with ~96% coupling efficiency. AB - We, for the first time, propose and theoretically study a plasmonic light steering concentrator (PLSC) that is based on a hybrid photonic-plasmonic sandwich structure. In this device, a transverse electric (TE) polarization guided mode supported by a silicon-on-insulator (SOI) waveguide is vertically coupled to a metal-dielectric-metal sandwich structure, while the structure steers the light to a perpendicular metal taper and focuses the light on the apex of the taper with a small radius of 15 nm. Based on the coupled-mode theory, the two supermodes (quasi-TM modes) are clarified to illustrate the coupling mechanism of the device. We numerically obtain over 96% coupling efficiency at the 1500 nm telecommunication wavelength, and the mode width supported by the apex is limited laterally within the range of ~110 nm, where the field enhancement calculated is found to be more than 107 compared to that of light in the silicon waveguide. PMID- 29460950 TI - Thrombocytopenia in leukemia: Pathogenesis and prognosis. AB - Leukemias, a heterogeneous group of hematological disorders, are characterized by ineffective hematopoiesis and morphologic abnormalities of hematopoietic cells. Thrombocytopenia is a common problem among leukemia types that can lead to hemorrhagic complications in patients. The purpose of this review article is to identify the conditions associated with the incidence of thrombocytopenia in leukemias. It can be stated that although translocations have been considered responsible for this complication in many studies, other factors such as bone marrow failure, genes polymorphism, a mutation in some transcription factors, and the adverse effects of treatment could be associated with pathogenesis and poor prognosis of thrombocytopenia in leukemias. Considering the importance of thrombocytopenia in leukemias, it is hoped that the recognition of risk factors increasing the incidence of this complication in leukemic patients would be useful for prevention and treatment of this disorder. PMID- 29460951 TI - Quantifying linear enamel hypoplasia in Virunga Mountain gorillas and other great apes. AB - OBJECTIVE: Linear enamel hypoplasia (LEH) is a condition marked by localized reductions in enamel thickness, resulting from growth disruptions during dental development. We use quantitative criteria to characterize the depth of LEH defects and "normal" perikymata in great apes. We test the hypothesis that mountain gorillas have shallow defects compared to other taxa, which may have led to their underestimation in previous studies. MATERIALS AND METHODS: Previous attempts to characterize LEH morphology quantitatively have been limited in sample size and scope. We generated digital elevation models using optical profilometry (Sensofar PLu Neox) and extracted 2D coordinates using ImageJ to quantify depths in canines from three great ape genera (N = 75 perikymata; 255 defects). RESULTS: All defect depths fall outside the distribution of perikymata depths. Mountain gorilla defects are significantly shallower than those of other great ape taxa examined, including western lowland gorillas. Females have significantly deeper defects than males in all taxa. The deepest defect belongs to a wild-captured zoo gorilla. Virunga mountain gorilla specimens collected by Dian Fossey exhibit deeper defects than those collected recently. DISCUSSION: Shallow defect morphology in mountain gorillas may have led to an underestimation of LEH prevalence in past studies. Defect depth is used as a proxy for insult severity, but depth might be influenced by inter- and intra-specific variation in enamel growth. Future studies should test whether severe insults are associated with deeper defects, as might be the case with Haloko, a wild-captured gorilla. Ongoing histologic studies incorporating associated behavioral records will test possible factors that underlie differences in defect morphology. PMID- 29460952 TI - Effects of hyaluronate-carboxymethylcellulose membranes on the clinical outcome of horses undergoing emergency exploratory celiotomy. AB - OBJECTIVE: To determine the influence of hyaluronate-carboxymethylcellulose (HA CMC) membranes applied to intestinal anastomoses or enterotomies on postoperative complications after emergency exploratory celiotomy. STUDY DESIGN: Multicenter retrospective case-controlled series. ANIMALS: Adult horses (59 in the HA-CMC group and 91 controls). METHODS: Medical records from 4 referral hospitals were searched for horses >=1 year of age, treated between 2008 and 2014 with emergency exploratory celiotomy, and surviving at least 24 hours postoperatively. Horses receiving repeat celiotomy during the same hospitalization were excluded. Horses who received HA-CMC were matched with controls who did not receive HA-CMC but had similar intestinal lesions and procedures at the same referral hospital. Postoperative complications (colic, nasogastric reflux, fever, incisional infection, and septic peritonitis), duration of hospitalization, and survival were compared between groups. Data were compared between horses by t test, Wilcoxon signed rank test, and chi2 test. RESULTS: The volume of nasogastric reflux at admission (P = .02) and the duration of administration of lidocaine after surgery (P = .02) were greater in horses with HA-CMC membranes than in controls. No difference in postoperative complications or survival was detected between groups: 48 of 59 (81%) horses treated with HA-CMC survived until discharge from the hospital compared with 80 of 91 (88%) horses in the control group (P = .27). Fifteen of 21 horses treated with HA-CMC and 30 of 43 horses in the control group survived >12 months after hospital discharge. CONCLUSION: Application of HA-CMC membranes to anastomoses or intestinal incisions did not influence postoperative complications or survival after emergency celiotomy compared with controls. CLINICAL SIGNIFICANCE: The safety and efficacy of HA-CMC membrane application to intestinal sites during colic surgery in horses is equivocal.

AB - Cantharellus tubaeformis was processed by pressurized hot water extraction (80 240 degrees C) with the aim of maximizing the extraction of oligomeric fractions, beta-glucans, and the in vitro antioxidant properties of the extracts. Increased severity of treatment enhanced the extraction yields above 62% at temperatures of 210oC or higher, corresponding to the maximum beta-glucan yields. The highest antioxidant capacity was obtained at 170oC, although the highest content of phenolic compounds was obtained at the highest severity studied. This hydrothermal treatment can be considered a suitable process to obtain extracts with antioxidant properties and rich in beta-glucans. PMID- 29460954 TI - Peptide ligand-mediated endocytosis of nanoparticles to cancer cells: Cell receptor-binding- versus cell membrane-penetrating peptides. AB - The endocytosis-mediating performances of two types of peptide ligands, cell receptor binding peptide (CRBP) and cell membrane penetrating peptide (CMPP), were analyzed and compared using a common carrier of peptide ligands-human ferritin heavy chain (hFTH) nanoparticle. Twenty-four copies of a CMPP(human immunodeficiency virus-derived TAT peptide) and/or a CRBP (peptide ligand with strong and specific affinity for either human integrin(alphav beta3 ) or epidermal growth factor receptor I (EGFR) that is overexpressed on various cancer cells) were genetically presented on the surface of each hFTH nanopariticle. The quantitative level of endocytosis and intracellular localization of fluorescence dye-labeled CRBP- and CMPP-presenting nanoparticles were estimated in the in vitro cultures of integrin- and EGFR-overexpressing cancer and human dermal fibroblast cells(control). From the cancer cell cultures treated with the CMPP- and CRBP-presenting nanoparticles, it was notable that CRBPs resulted in quantitatively higher level of endocytosis than CMPP (TAT) and successfully transported the nanoparticles to the cytosol of cancer cells depending on concentration and treatment period of time, whereas TAT-mediated endocytosis localized most of the nanoparticles within endosomal vesicles under the same conditions. These novel findings provide highly useful informations to many researchers both in academia and in industry who are interested in developing anticancer drug delivery systems/carriers. PMID- 29460955 TI - A pilot study: Can the UFOV assessment be used as a repeated measure to determine timing of on-road assessment in stroke? AB - BACKGROUND/AIMS: Useful Field of View scores are predictive of on-road performance post-stroke. No objective data exist to determine if the Useful Field of View (UFOV) assessment can be used as a repeated measure in the post-stroke population to determine timing of occupational therapy on-road assessment as recovery occurs. The aims of this study were to determine whether there is a practice effect if the UFOV is administered at one, two and three months' post stroke and to assess optimal time post-stroke to refer to an on-road assessment. METHOD: Forty-two participants, 17 men (40.5%), with a mean age of 71 years (SD 9.33) were randomly allocated to 1. Assessment group - UFOV at one, two and three months' post-stroke, 2. Control group-UFOV at three months' post-stroke. Parametric and non-parametric tests were utilised depending on data distribution. RESULTS: No significance was found between; three months' subtest 1 (P = 0.463), three months' subtest 2 (P = 0.729) and three months' subtest 3 (P = 0.534) between the assessment and control groups. Both group's scores were combined to examine pass/fail rates of UFOV assessment to indicate timing of referral to on road assessments. At one month, 16.9% stroke survivors passed the UFOV, when reassessed at three months 69.1% passed and 28.6% again failed. CONCLUSION: Improvements in scores at one month intervals over three months are due to improvements in abilities assessed by the UFOV as no practice effect was found to influence scores. UFOV scores performed at monthly intervals post-stroke can be used to guide the timing of an occupational therapy on-road assessment, with an increased likelihood of passing, as recovery occurs. This repeated use of the UFOV assessment can assist referral practices that best utilise driving rehabilitation programmes. Larger studies need to be conducted to confirm these results.

PMID- 29460957 TI - Mosaicism of de novo pathogenic SCN1A variants in epilepsy is a frequent phenomenon that correlates with variable phenotypes. AB - OBJECTIVE: Phenotypes caused by de novo SCN1A pathogenic variants are very variable, ranging from severely affected patients with Dravet syndrome to much milder genetic epilepsy febrile seizures plus cases. The most important determinant of disease severity is the type of variant, with variants that cause a complete loss of function of the SCN1A protein (alpha-subunit of the neuronal sodium channel Nav1.1) being detected almost exclusively in Dravet syndrome patients. However, even within Dravet syndrome disease severity ranges greatly, and consequently other disease modifiers must exist. A better prediction of disease severity is very much needed in daily practice to improve counseling, stressing the importance of identifying modifying factors in this patient group. We evaluated 128 participants with de novo, pathogenic SCN1A variants to investigate whether mosaicism, caused by postzygotic mutation, is a major modifier in SCN1A-related epilepsy. METHODS: Mosaicism was investigated by reanalysis of the pathogenic SCN1A variants using single molecule molecular inversion probes and next generation sequencing with high coverage. Allelic ratios of pathogenic variants were used to determine whether mosaicism was likely. Selected mosaic variants were confirmed by droplet digital polymerase chain reaction and sequencing of different tissues. Developmental outcome was classified based on available data on intelligence quotient and school functioning/education. RESULTS: Mosaicism was present for 7.5% of de novo pathogenic SCN1A variants in symptomatic patients. Mosaic participants were less severely affected than nonmosaic participants if only participants with truncating variants are considered (distribution of developmental outcome scores, Mann-Whitney U, P = .023). SIGNIFICANCE: Postzygotic mutation is a common phenomenon in SCN1A-related epilepsies. Participants with mosaicism have on average milder phenotypes, suggesting that mosaicism can be a major modifier of SCN1A-related diseases. Detection of mosaicism has important implications for genetic counseling and can be achieved by deep sequencing of unique reads.

AB - BACKGROUND: Despite the increasing population of elderly individuals in Korea, there are no evidence-based geriatric nursing practice guidelines. AIM: This study aimed to identify and prioritize topics related to the development of evidence-based geriatric nursing practice guidelines in long-term care facilities in Korea. METHODS: To identify potential topics, 89 nurses responded to a questionnaire on activities that require further evidence and/or standardization in the long-term care facility setting. To prioritize these topics, 14 geriatric nursing experts completed surveys to prioritize five categories. RESULTS: The collected data included 240 clinical topics, which were classified into 41 subcategories and 18 main categories. According to topic prioritization by the geriatric nursing experts, the following were the most heavily weighted categories: fall prevention, position change and prevention of pressure ulcers. CONCLUSIONS: The development of standardized guidelines based on these results may help improve the quality of geriatric care and quality of life of older individuals. The small number of respondents may be a limitation of this study, and further study is needed to expand the population. IMPLICATIONS FOR NURSING AND HEALTH POLICY: The development of evidence-based nursing guidelines based on the present findings will help improve the quality of nursing in long-term care facilities. Additionally, health policies and systems, such as introduction of a fee for nursing services for older individuals based on the evidence, are worth considering.

PMID- 29460958 TI - Harnessing a methane-fueled, sediment-free mixed microbial community for utilization of distributed sources of natural gas. AB - Harnessing the metabolic potential of uncultured microbial communities is a compelling opportunity for the biotechnology industry, an approach that would vastly expand the portfolio of usable feedstocks. Methane is particularly promising because it is abundant and energy-rich, yet the most efficient methane activating metabolic pathways involve mixed communities of anaerobic methanotrophic archaea and sulfate reducing bacteria. These communities oxidize methane at high catabolic efficiency and produce chemically reduced by-products at a comparable rate and in near-stoichiometric proportion to methane consumption. These reduced compounds can be used for feedstock and downstream chemical production, and at the production rates observed in situ they are an appealing, cost-effective prospect. Notably, the microbial constituents responsible for this bioconversion are most prominent in select deep-sea sediments, and while they can be kept active at surface pressures, they have not yet been cultured in the lab. In an industrial capacity, deep-sea sediments could be periodically recovered and replenished, but the associated technical challenges and substantial costs make this an untenable approach for full-scale operations. In this study, we present a novel method for incorporating methanotrophic communities into bioindustrial processes through abstraction onto low mass, easily transportable carbon cloth artificial substrates. Using Gulf of Mexico methane seep sediment as inoculum, optimal physicochemical parameters were established for methane-oxidizing, sulfide-generating mesocosm incubations. Metabolic activity required >~40% seawater salinity, peaking at 100% salinity and 35 degrees C. Microbial communities were successfully transferred to a carbon cloth substrate, and rates of methane-dependent sulfide production increased more than threefold per unit volume. Phylogenetic analyses indicated that carbon cloth based communities were substantially streamlined and were dominated by Desulfotomaculum geothermicum. Fluorescence in situ hybridization microscopy with carbon cloth fibers revealed a novel spatial arrangement of anaerobic methanotrophs and sulfate reducing bacteria suggestive of an electronic coupling enabled by the artificial substrate. This system: 1) enables a more targeted manipulation of methane-activating microbial communities using a low-mass and sediment-free substrate; 2) holds promise for the simultaneous consumption of a strong greenhouse gas and the generation of usable downstream products; and 3) furthers the broader adoption of uncultured, mixed microbial communities for biotechnological use.

PMID- 29460962 TI - Glycosphingolipidomics of donkey milk by hydrophilic interaction liquid chromatography coupled to ESI and multistage MS. AB - Hydrophilic interaction liquid chromatography coupled to negative-ion electrospray linear ion-trap multiple-stage MS (HILIC-ESI-MSn , n = 2,3) was used to characterize polar lipids occurring in donkey milk. Besides the detection of abundant phospholipids, the structural characterization and content evaluation of minor glycosphingolipids (GSLs) were assessed. We report an unprecedented characterization of 11 hexosyl-ceramides (HexCer), 10 Hex2 Cer, and 4 Hex3 Cer. CID-MS/MS spectra in negative ion mode mainly afford information on the monosaccharide number and ceramide constitution (i.e., N-acyl residue and long chain base), whereas MS/MS/MS spectra on the ceramide anions allow to recognize for each GSL the sphingoid base. The occurrence of sphingosine (S), sphinganine (DS), and phytosphingosine (P) was inferred from the fragmentation patterns. The milk samples exhibit a relatively high number of phytosphingosine substitutes, perhaps because of the feeding of donkeys, mainly based on pasture grass. However, the incidence of hydroxylated species on the alpha-carbon of the acyl chain was also revealed. The fatty acid composition of N-acyl chains showed high values of long-chain saturated fatty acids such as 20:0, 22:0, 23:0, and 24:0. An average content of GSL is also provided and three representative mono-, di-, and tri-HexCer in donkey milk are the following: HexCer 18:0/24:1 phytosphingosine nonhydroxylated [PN] at m/z 862.6 as chloride adduct [M+Cl]- , and content 225.9 +/- 2.8 MUg 100 mL-1 ; Hex2 Cer 18:0/16:0 sphinganine nonhydroxylated [DSN] at m/z 862.7 as deprotonated adduct [M-H]- , and content 70.8 +/- 1.4 MUg 100 mL-1 ; and Hex3 Cer 18:1/24:1 [SN] at m/z 1132.8 as [M-H]- , and content 38.5 +/- 0.7 MUg 100 mL-1 .

AB - Water acquisition is thought to be limited to the unsuberized surface located close to root tips. However, there are recurring periods when the unsuberized surfaces are limited in woody root systems, and radial water uptake across the bark of woody roots might play an important physiological role in hydraulic functioning. Using X-ray microcomputed tomography (microCT) and hydraulic conductivity measurements (Lpr ), we examined water uptake capacity of suberized woody roots in vivo and in excised samples. Bark hydration in grapevine woody roots occurred quickly upon exposure to water (c. 4 h). Lpr measurements through the bark of woody roots showed that it is permeable to water and becomes more so upon wetting. After bark hydration, microCT analysis showed that absorbed water was utilized to remove embolism locally, where c. 20% of root xylem vessels refilled completely within 15 h. Embolism removal did not occur in control roots without water. Water uptake through the bark of woody roots probably plays an important role when unsuberized tissue is scarce/absent, and would be particularly relevant following large irrigation events or in late winter when soils are saturated, re-establishing hydraulic functionality before bud break. PMID- 29460964 TI - Comparison between 8-methoxypsoralen and 5-aminolevulinic acid in killing T cells of photopheresis patients ex vivo. AB - BACKGROUND AND OBJECTIVE: Extracorporeal photopheresis (ECP), an established modality for cutaneous T-cell lymphoma (CTCL) and graft-versus-host disease, involves ex vivo treatment of isolated leukocytes of a patient with the photosensitizing drug 8-methoxypsoralen (8-MOP) and ultraviolet-A (UV-A) exposure before reinfusion back to the patient. However, 8-MOP binds to both diseased and normal cells and thus kills both types of the cells after UV-A illumination with little selectivity. Clinically, this modality gives only partial response in the majority of treated patients. 5-Aminolevulinic acid (5-ALA), a precursor of the potent photosensitizer protoporphyrin IX (PpIX), has been shown to selectively induce PpIX in activated T lymphocytes (T cells) and could be an alternative for 8-MOP. The objectives of this study were to investigate ex vivo 5-ALA dark toxicity, 5-ALA-induced PpIX production, and photodynamic effect on T cells obtained from clinical ECP patients after the treatment of 5-ALA or 8-MOP plus a built-in certified UV-A source in the commercial TherakosTM Photopheresis System. MATERIALS AND METHODS: Flow cytometry was used to study dark cytotoxic effects of 5-ALA on human leukocytes, to measure the production of 5-ALA-induced PpIX in CD25+ activated T cells from both diluted mononuclear cells and undiluted buffy coat samples of ECP patients and to compare photodynamic effects on CD4+ and CD8+ T cells with 5-ALA/UV-A or 8-MOP/UV-A. RESULTS: No dark toxicity of 5-ALA on the leukocytes of ECP patients was seen at concentrations up to 10 mM for an incubation of up to 20 hours. 5-ALA-induced PpIX was produced more in CD25+ activated T cells than resting T cells in both diluted mononuclear cells and undiluted buffy coat samples, although there was a huge variation of samples from different individual patients. The CD4+ and CD8+ T cells treated with 5-ALA/UV-A were killed more than those treated with 8-MOP/UV-A. CONCLUSION: These results suggest that 5-ALA/UV-A may have the potential for improving the efficacy of ECP. Lasers Surg. Med. 50:469-475, 2018. (c) 2018 Wiley Periodicals, Inc.

AB - Previous research has examined how the talk of mediums attends to the epistemological status of their readings. Such work has identified that mediums frequently use question-framed propositions that are typically confirmed by the sitter, thereby conferring epistemological status on the medium. This study seeks to investigate what happens when the sitter disconfirms the propositions of the medium. The study focuses on the ways in which such disconfirmation can be responded to such that it is reconstrued as evidence of the psychic nature of the medium's reading. Televised demonstrations of psychic readings involving British and US mediums and their sitters are analysed. The results suggest that mediums rework disconfirmation as proof in several ways: first, by emphasizing the different access that sitter and medium have to knowledge (e.g., about the future); second, as evidence that the medium has access to the actual voice of the deceased (and may therefore mishear what the deceased has said to them); and third, as revealing an important truth that has hitherto been concealed from the sitter. The implications of these findings are considered for cases where speakers bring different and potentially competing, epistemological resources to an interaction. PMID- 29460967 TI - Tumescent contravenom: murine model for prehospital treatment of Naja naja neurotoxic snake envenomation. AB - BACKGROUND: Snake envenomation is a neglected global health problem. There is a need for a prehospital treatment of neurotoxic snakebite that prolongs survival and allows time for a victim to reach a hospital for antivenom therapy. Tumescent epinephrine consists of a large volume of dilute epinephrine (2 mg/l) injected subcutaneously. It functions as "contravenom" by causing capillary vasoconstriction and delaying venom absorption. METHODS: A murine model of neurotoxic envenomation using lidocaine as a surrogate for neurotoxic snake venom was first developed in a pilot study. A lethal dose of lidocaine was injected subcutaneously into control and treatment groups. Mice in the treatment group were then treated with a tumescent infiltration of dilute epinephrine in saline, while control mice either received no treatment or tumescent infiltration with saline alone. The experiment was repeated using lethal doses of neurotoxic Naja naja cobra venom. The main end-points were survival rate and survival time. RESULTS: None of the control mice survived a lethal (LD100 ) dosage of subcutaneous lidocaine. Mice given an LD100 of subcutaneous lidocaine and treated immediately with tumescent epinephrine had 80% survival. Following LD50 doses of Naja naja venom, 50% of control mice survived, while 94% survived when treated immediately with tumescent epinephrine (P < 0.01). All animals died following LD100 doses of Naja naja venom, but survival was significantly prolonged (P < 0.0001) by immediate tumescent epinephrine. CONCLUSIONS: Tumescent epinephrine, when given immediately after toxin injection, improves survival rates in mice following neurotoxic doses of lidocaine or Naja naja cobra venom. PMID- 29460969 TI - Exploring complaints by female and male patients at Swedish hospitals using a probabilistic graphical model. AB - BACKGROUND: Patients' complaints have been highlighted as important for constructively improving healthcare services. In so doing, it may be important to identify disparities in experiences based on patients' demographics, such as sex. AIM: To explore hospital recorded complaints addressing potential sex differences and whether complaints were reported by the patient or a relative. METHODS: Quantitative study of all 835 closed patient complaints during 2013 at three mid sized hospitals in Sweden. The complaints were categorisation based on perceived quality theory and analysed using a probabilistic graphical model. The findings were validated through qualitative interviews. FINDINGS: Female patients were more likely than male patients to report dissatisfaction with interpersonal issues, whereas male patients were more likely to report dissatisfaction with administration. If a complaint from a male patient had been reported by a relative, the matter was more likely to be interpersonal. Improvement suggestions were predominantly reported by staff. However, patients and relatives proved more likely than staff to report improvement suggestions when dissatisfied with interpersonal matters. CONCLUSION: Using a Bayesian network, this article suggests that complaints in health care should be more holistically understood and the factors should be viewed as interconnected. This article addresses complaints as an important source of identifying not only perceived healthcare deficiencies and sex disparities, but also improvement suggestions. PMID- 29460968 TI - Angioedema in chronic spontaneous urticaria is underdiagnosed and has a substantial impact: Analyses from ASSURE-CSU. AB - BACKGROUND: ASSURE-CSU revealed differences in physician and patient reporting of angioedema. This post hoc analysis was conducted to evaluate the actual rate of angioedema in the study population and explore differences between patients with and without angioedema. METHODS: This international observational study assessed 673 patients with inadequately controlled chronic spontaneous urticaria (CSU). Physicians abstracted angioedema data from medical records, which were compared with patient-reported data. Patients in the Yes-angioedema category had angioedema reported in the medical record and a patient-reported source. For those in the No-angioedema category, angioedema was reported in neither the medical record nor a patient-reported source. Those in the Misaligned category had angioedema reported in only one source. Statistical comparisons between Yes angioedema and No-angioedema categories were conducted for measures of CSU activity, health-related quality of life (HRQoL), productivity and healthcare resource utilization (HCRU). Regression analyses explored the relationship between Dermatology Life Quality Index (DLQI) score and angioedema, adjusting for important covariates. RESULTS: Among evaluable patients, 259 (40.3%), 173 (26.9%) and 211 (32.8%) were in the Yes-angioedema, No-angioedema and Misaligned category, respectively. CSU activity and impact on HRQoL, productivity, and HCRU was greater for Yes-angioedema patients than No-angioedema patients. After covariate adjustment, mean DLQI score was significantly higher (indicating worse HRQoL) for patients with angioedema versus no angioedema (9.88 vs 7.27, P < .001). The Misaligned category had similar results with Yes-angioedema on all outcomes. CONCLUSIONS: Angioedema in CSU seems to be under-reported but has significant negative impacts on HRQoL, daily activities, HCRU and work compared with no angioedema. PMID- 29460970 TI - Clinical application research through reflection, interpretation and new understanding - a hermeneutic design. AB - The implementation of theoretical knowledge in clinical practice and the implementation of good clinical practice into theory have been of interest in caring science for the last 30 years. The aim of this article was to elaborate and discuss a methodology named clinical application research. The method is grounded in a hermeneutical design inspired by Gadamer's philosophy. The methodology, clinical application research, has been used in a research project A life in dignity and experiences from the researchers forms the bases for the elaboration and discussion. The project was performed in collaboration with residents, family caregivers and healthcare providers at six nursing homes in Scandinavia. The material for this article is based on the previous research, that is the results from 10 different articles showing the meaning of dignity and indignity in daily life in nursing homes. Data were generated from 56 individual interviews and 18 focus-group interviews with a total of 40 staff members with five to eight participants at every interview session. By reflection, interpretation and new understanding our results provide knowledge about dignity and how to preserve dignity for older people in an appropriate ethical way. The methodology was relevant for the research project A life in dignity and relevant to caring practice in nursing homes as it opens new possibilities and new ways of thinking when performing dignified care to older people. PMID- 29460972 TI - Alteration of renal excretion pathways in gentamicin-induced renal injury in rats. AB - The kidney plays a major part in the elimination of many drugs and their metabolites, and drug-induced kidney injury commonly alters either glomerular filtration or tubular transport, or both. However, the renal excretion pathway of drugs has not been fully elucidated at different stages of renal injury. This study aimed to evaluate the alteration of renal excretion pathways in gentamicin (GEN)-induced renal injury in rats. Results showed that serum cystatin C, creatinine and urea nitrogen levels were greatly increased by the exposure of GEN (100 mg kg-1 ), and creatinine concentration was increased by 39.7% by GEN (50 mg kg-1 ). GEN dose-dependently upregulated the protein expression of rOCT1, downregulated rOCT2 and rOAT1, but not affected rOAT2. Efflux transporters, rMRP2, rMRP4 and rBCRP expressions were significantly increased by GEN(100), and the rMATE1 level was markedly increased by GEN(50) but decreased by GEN(100). GEN(50) did not alter the urinary excretion of inulin, but increased metformin and furosemide excretion. However, GEN(100) resulted in a significant decrease of the urinary excretion of inulin, metformin and p-aminohippurate. In addition, urinary metformin excretions in vivo were significantly decreased by GEN(100), but slightly increased by GEN(50). These results suggested that GEN(50) resulted in the induction of rOCTs-rMATE1 and rOAT3-rMRPs pathway, but not changed the glomerular filtration rate, and GEN(100)-induced acute kidney injury caused the downregulated function of glomerular filtration -rOCTs-rMATE1 and -rOAT1-rMRPs pathway. PMID- 29460971 TI - Quantification of Muscle Tissue Properties by Modeling the Statistics of Ultrasound Image Intensities Using a Mixture of Gamma Distributions in Children With and Without Cerebral Palsy. AB - OBJECTIVES: To investigate whether quantitative ultrasound (US) imaging, based on the envelope statistics of the backscattered US signal, can describe muscle properties in typically developing children and those with cerebral palsy (CP). METHODS: Radiofrequency US data were acquired from the rectus femoris muscle of children with CP (n = 22) and an age-matched cohort without CP (n = 14) at rest and during maximal voluntary isometric contraction. A mixture of gamma distributions was used to model the histogram of the echo intensities within a region of interest in the muscle. RESULTS: Muscle in CP had a heterogeneous echo texture that was significantly different from that in healthy controls (P < .001), with larger deviations from Rayleigh scattering. A mixture of 2 gamma distributions showed an excellent fit to the US intensity, and the shape and rate parameters were significantly different between CP and control groups (P < .05). The rate parameters for both the single gamma distribution and mixture of gamma distributions were significantly higher for contracted muscles compared to resting muscles, but there was no significant interaction between these factors (CP and muscle contraction) for a mixed-model analysis of variance. CONCLUSIONS: Ultrasound tissue characterization indicates a more disorganized architecture and increased echogenicity in muscles in CP, consistent with previously documented increases in fibrous infiltration and connective tissue changes in this population. Our results indicate that quantitative US can be used to objectively differentiate muscle architecture and tissue properties. PMID- 29460973 TI - Towards an analytic solution for pulsed CEST. AB - Chemical exchange saturation transfer (CEST) is an imaging method based on magnetization exchange between solutes and water. This exchange generates changes in the measured signal after off-resonance radiofrequency irradiation. Although the analytic solution for CEST with continuous wave (CW) irradiation has been determined, most studies are performed using pulsed irradiation. In this work, we derive an analytic solution for the CEST signal after pulsed irradiation that includes both short-time rotation effects and long-time saturation effects in a two-pool system corresponding to water and a low-concentration exchanging solute pool. Several approximations are made to balance the accuracy and simplicity of the resulting analytic form, which is tested against numerical solutions of the coupled Bloch equations and is found to be largely accurate for amides at high fields, but less accurate at the higher exchange rates, lower offsets and typically higher irradiation powers of amines.

AB - To investigate the level variation of correlative factors between the spermatic vein plexus and peripheral blood in patients with varicocele, a total of 22 patients diagnosed with varicocele were enrolled in the study. All patients were performed a testicular artery-sparing microsurgical varicocelectomy. During the operation, a blood sample from the left spermatic vein plexus and a peripheral blood sample were collected. A radioimmunoassay was used to determine the 6-keto prostaglandin F1a (6-keto-PGF1a ). A colorimetric method was performed to determine the NO. The enzyme immunoassay method was used to determine the creatinine, urea nitrogen, adrenaline, noradrenaline, dopamine and 5-HT. The mean age of all patients was 29.3 +/- 7.8 years. Compared with the level of 6-keto PGF1a and NO in the peripheral blood, 6-keto-PGF1a and NO were significantly increased in left spermatic vein plexus (347.3 (230.8-415.1) versus 99.7 (80.4 119.9) pg/ml and 192.3 +/- 178.5 versus 107.1 +/- 73.6 MUmol/L, p < .05). There were no differences in the level of creatinine, urea nitrogen, adrenaline, noradrenaline, dopamine and 5-HT between the peripheral blood and left spermatic vein plexus (p > .05). The 6-keto-PGF1a and NO concentrations in left spermatic vein plexus were significantly higher than that in peripheral blood patients with varicocele.

PMID- 29460976 TI - Vein wrapping promotes M2 macrophage polarization in a rat chronic constriction injury model. AB - Although the therapeutic potential of vein wrapping (VW) for recurrent compressive neuropathy has been widely reported, the mechanisms underlying this technique have not been characterized. M2 macrophages induced by interleukin-4 (IL-4) or interleukin-10 (IL-10) have an anti-inflammatory function and play an important role in peripheral nerve repair. To evaluate whether VW promotes M2 polarization, we divided chronic constriction injury (CCI) rats into untreated and VW (CCI + VW)-treated groups. Pain withdrawal thresholds in both groups were evaluated using von Frey filaments. Expression of the anti-inflammatory cytokines IL-4 and IL-10 in vein and nerve were quantified using real time polymerase chain reaction (RT-PCR), and expression of the anti-inflammatory M2 macrophage markers CD206 and arginase-1 (Arg1) after VW was assessed by RT-PCR and immunohistochemistry. To evaluate the effect of exogenous IL-4 or IL-10 on M2 macrophage-marker expression, CD11b-positive macrophages isolated from sciatic nerve were stimulated with recombinant IL-4 and IL-10. VW significantly increased the pain withdrawal threshold. IL-4 and IL-10 mRNA expression was higher in veins than in the sciatic nerve. VW significantly increased CD206 and Arg1 mRNA expression compared to the CCI group. The number of CD206- and Arg1 immunoreactive cells in nerve bundles was twofold higher in the CCI + VW than CCI group. Application of exogenous IL-4 doubled CD206 and Arg1 mRNA expression in CD11b-positive macrophages. These results show that vein-derived IL-4 potentiates the benefit of VW through the activation of M2 macrophages in the sciatic nerve. Our results may help to optimize current procedures for treating recurrent compressive neuropathy. (c) 2018 Orthopaedic Research Society. Published by Wiley Periodicals, Inc. J Orthop Res. PMID- 29460977 TI - Development of a screening tool using electronic health records for undiagnosed Type 2 diabetes mellitus and impaired fasting glucose detection in the Slovenian population. AB - AIM: To develop and validate a simplified screening test for undiagnosed Type 2 diabetes mellitus and impaired fasting glucose for the Slovenian population (SloRisk) to be used in the general population. METHODS: Data on 11 391 people were collected from the electronic health records of comprehensive medical examinations in five Slovenian healthcare centres. Fasting plasma glucose as well as information related to the Finnish Diabetes Risk Score questionnaire, FINDRISC, were collected for 2073 people to build predictive models. Bootstrapping-based evaluation was used to estimate the area under the receiver operating characteristic curve performance metric of two proposed logistic regression models as well as the Finnish Diabetes Risk Score model both at recommended and at alternative cut-off values. RESULTS: The final model contained five questions for undiagnosed Type 2 diabetes prediction and achieved an area under the receiver-operating characteristic curve of 0.851 (95% CI 0.850-0.853). The impaired fasting glucose prediction model included six questions and achieved an area under the receiver-operating characteristic curve of 0.840 (95% CI 0.839 0.840). There were four questions that were included in both models (age, sex, waist circumference and blood sugar history), with physical activity selected only for undiagnosed Type 2 diabetes and questions on family history and hypertension drug use selected only for the impaired fasting glucose prediction model. CONCLUSIONS: This study proposes two simplified models based on FINDRISC questions for screening of undiagnosed Type 2 diabetes and impaired fasting glucose in the Slovenian population. A significant improvement in performance was achieved compared with the original FINDRISC questionnaire. Both models include waist circumference instead of BMI.

AB - Naevus sebaceous (NS) is a congenital cutaneous hamartoma, which typically occurs on the head and neck. Historically, the treatment of choice was excision in infancy because of the potential for malignant transformation; however, recent studies suggest that this risk is < 1% and unlikely in childhood. We sent a questionnaire to UK dermatologists and plastic surgeons to investigate current management practice of NS. We found that almost a third of dermatologists still recommend excision for malignancy prevention, while over 90% of plastic surgeons consider excision, with 64% citing malignancy prevention as the reason. Plastic surgeons most commonly recommended excision in childhood, whereas dermatologists waited until adulthood. We have shown there is significant variation in practice across the UK in the management of naevus NS. It is important that patients across the UK receive the same standard of care, and therefore we advocate the development of evidence-based guidance for treatment of naevus NS.

AB - BACKGROUND: Focal embouchure dystonia impairs orofacial motor control in wind musicians and causes professional disability. A paucity of quantitative measures or rating scales impedes the objective assessment of treatment efficacy. OBJECTIVES: We quantified specific features of focal embouchure dystonia using acoustic measures and developed a metric to assess severity across multiple domains of symptomatic impairment. METHODS: We recruited 9 brass musicians with and 6 without embouchure dystonia. The following 4 domains of symptomatic dysfunction in focal embouchure dystonia were identified: pitch inaccuracy, sound instability and tremor, sound breaks, and timing variability. Musicians performed sustained tones and sequences, and then acoustic variables within each domain were quantified. A composite brass acoustic severity score composed of these variables was validated against clinical global impressions of severity. RESULTS: Musicians with dystonia performed worse in acoustic domains of pitch inaccuracy (median: dystonia = 100%, control = 62%), instability (median shimmer: dystonia = 3%, control = 2%), and breaks (median: dystonia = 0.34%, control = 0.05%). Tremor in embouchure dystonia was 5 to 8 Hz, intermittent, and variable in amplitude. Rhythmic variability did not differ between groups. Participants with embouchure dystonia had different patterns of impairment across variables. Composite severity scores strongly predicted clinical global impression of severity (R2 = 0.95). CONCLUSIONS: Acoustic variables distinguish musicians with embouchure dystonia from controls and reflect different types of symptomatic impairments. Our composite acoustic severity score predicts severity of clinical global impression for musicians with different patterns of symptomatic impairment and may provide a foundation for developing a clinical rating scale.

AB - Previous evidence highlighted the multisensory-motor origin of embodiment - that is, the experience of having a body and of being in control of it - and the possibility of experimentally manipulating it. For instance, an illusory feeling of embodiment towards a fake hand can be triggered by providing synchronous visuo tactile stimulation to the hand of participants and to a fake hand or by asking participants to move their hand and observe a fake hand moving accordingly (rubber hand illusion). Here, we tested whether it is possible to manipulate embodiment not through stimulation of the participant's hand, but by directly tapping into the brain's hand representation via non-invasive brain stimulation. To this aim, we combined transcranial magnetic stimulation (TMS), to activate the hand corticospinal representation, with virtual reality (VR), to provide matching (as contrasted to non-matching) visual feedback, mimicking involuntary hand movements evoked by TMS. We show that the illusory embodiment occurred when TMS pulses were temporally matched with VR feedback, but not when TMS was administered outside primary motor cortex, (over the vertex) or when stimulating motor cortex at a lower intensity (that did not activate peripheral muscles). Behavioural (questionnaires) and neurophysiological (motor-evoked-potentials, TMS evoked-movements) measures further indicated that embodiment was not explained by stimulation per se, but depended on the temporal coherence between TMS-induced activation of hand corticospinal representation and the virtual bodily feedback. This reveals that non-invasive brain stimulation may replace the application of external tactile hand cues and motor components related to volition, planning and anticipation. PMID- 29460983 TI - Transcriptional profiling of synovium in a porcine model of early post-traumatic osteoarthritis. AB - To determine the transcriptional profile of synovium during the molecular phase of post-traumatic osteoarthritis, anterior cruciate ligament transections (ACL) were performed in 36 Yucatan minipigs. Equal numbers were randomly assigned to no further treatment, ACL reconstruction or repair. Perimeniscal synovium for histopathology and RNA-sequencing was harvested at 1 and 4 weeks post-operatively and from six healthy control animals. Microscopic synovitis scores significantly worsened at 1 (p < 0.001) and 4 weeks (p = 0.003) post-surgery relative to controls, and were driven by intimal hyperplasia and increased stromal cellularity without inflammatory infiltrates. Synovitis scores were similar between no treatment, reconstruction, and repair groups (p >= 0.668). Relative to no treatment at 1 week, 88 and 367 genes were differentially expressed in the reconstruction and repair groups, respectively (227 and 277 at 4 weeks). Relative to controls and with the treatment groups pooled, 1,683 transcripts were concordantly differentially expressed throughout the post-surgery time-course. Affected pathways included, proteolysis_connective tissue degradation (including upregulations of protease-encoding MMP1, MMP13, and ADAMTS4), and development_cartilage development (including upregulations of ACAN, SOX9, and RUNX2), among others. Using linear regression, significant associations of post surgery synovial expression levels of 20 genes with the articular cartilage glycosaminoglycan loss were identified. These genes were predominantly related to embryonic skeletal system development and included RUNX2. In conclusion, this study confirmed an increased synovial expression of genes that may serve as targets to prevent cartilage degradation, including MMP1, MMP13, and ADAMTS4, in knees with microscopic synovitis and cartilage proteoglycan loss. Attractive novel targets include regulators of embryonic developmental processes in synovium. (c) 2018 Orthopaedic Research Society. Published by Wiley Periodicals, Inc. J Orthop Res.

AB - BACKGROUND: Studies suggesting a protective effect of estrogen in neurodegenerative diseases prompted us to investigate this relationship in progressive supranuclear palsy (PSP). METHODS: This case-control study evaluated the self-reported reproductive characteristics and estrogen of 150 women with PSP and 150 age-matched female controls who participated in the Environmental Genetic PSP study. Conditional logistic regression models were generated to examine associations of PSP with estrogen. RESULTS: There was no association between years of estrogen exposure duration and PSP. There was a suggestion of an inverse association between composite estrogen score and PSP that did not reach statistical significance (P = .06). Any exposure to estrogen replacement therapy halved the risk of PSP (odds ratio = 0.52; 95% confidence interval = 0.30-0.92; P = .03). Among PSP cases, earlier age at menarche was associated with better performance on Hoehn and Yahr stage (beta = -0.60; SE = 0.26; P = .02) and Unified Parkinson's Disease Rating Scale II score (beta = -5.19; SE = 2.48; P = .04) at clinical examination. CONCLUSIONS: This case-control study suggests a protective role of lifetime estrogen exposure in PSP. Future studies will be needed to confirm this association.

AB - Osteochondritis dissecans is a joint disease that is observed in several species. The disease can develop as a cause of ischemic chondronecrosis in the epiphyseal growth cartilage. Some lesions of chondronecrosis undergo spontaneous resolution, but it is not possible to predict whether a lesion will resolve or progress and require intervention. Proliferation of cells into clusters occurs at the lesion margin, but it is unclear if the clusters have a repair function. The aims of the current study were to examine clusters and potential matrix changes in response to ischemic chondronecrosis in the distal femur of 10 pigs aged 70-180 days using advanced microscopy based on two-photon excitation fluorescence and second harmonic generation. These microscopy techniques can perform 3D imaging of cells and collagen without staining. The results indicated a lower collagen density in the chondronecrotic areas compared to the normal growth cartilage, and fissures and breaks in the matrix integrity were demonstrated that potentially can propagate and cause osteochondritis dissecans. A higher number of cells in clusters was correlated with reduction in collagen density in the lesions. Some of the cells in the clusters had a morphology similar to progenitor cells, suggesting a potential repair role of the clusters. The study has shed further light on the secondary responses after initial lesion formation, which information can be of potential use to create models that can predict lesion progression and that may hence avoid unnecessary interventions in the future.

AB - INTRODUCTION: The dynamic headspace sampling technique using thermal desorption, gas chromatography-mass spectrometry (TD-GC/MS) is a powerful method for analysing plant emissions of volatile organic compounds (VOCs), and experiments performed in sterile and controlled conditions can be useful for VOC metabolism investigations. OBJECTIVE: The main purpose of this study was to set up a laboratory high-throughput glass chamber for whole plant volatiles analysis. Brassica napus L. plantlets were tested with the developed system to better understand the relationship between low emission of induced terpene and cadmium (Cd)-related abiotic stress. METHODOLOGY: VOCs emitted by 28-day-old Brassica napus L. plantlets cultivated in vitro were trapped with our device using adsorbent cartridges that were desorbed with a thermal desorption unit before cryofocusing with a cooled injection system and programmable temperature vaporising inlet into an HP-5 ms GC column. Terpene detection and quantitation from chromatogram profiles were acquired using selected ion monitoring (SIM) mode during full scan analysis and mass spectra were obtained with a quadrupole-type mass spectrometer. RESULTS: The new trapping method produced reliable qualitative profiles of oilseed rape VOCs. Typical emissions of monoterpenes (myrcene, limonene) and sesquiterpenes (beta-elemene, (E,E)-alpha-farnesene) were found for the different concentrations tested. One-way analysis of variance for quantitative results of (E,E)-alpha-farnesene emission rates showed a Cd concentration effect. CONCLUSION: This inexpensive glass chamber has potential for wide application in laboratory sterile approach and replicated research. Moreover, the non-invasive dynamic sampling technique could also be used to analyse volatiles under both abiotic and biotic stresses. PMID- 29460986 TI - Text-mined phenotype annotation and vector-based similarity to improve identification of similar phenotypes and causative genes in monogenic disease patients. AB - The genetic diagnosis of rare monogenic diseases using exome/genome sequencing requires the true causal variant(s) to be identified from tens of thousands of observed variants. Typically a virtual gene panel approach is taken whereby only variants in genes known to cause phenotypes resembling the patient under investigation are considered. With the number of known monogenic gene-disease pairs exceeding 5,000, manual curation of personalized virtual panels using exhaustive knowledge of the genetic basis of the human monogenic phenotypic spectrum is challenging. We present improved probabilistic methods for estimating phenotypic similarity based on Human Phenotype Ontology annotation. A limitation of existing methods for evaluating a disease's similarity to a reference set is that reference diseases are typically represented as a series of binary (present/absent) observations of phenotypic terms. We evaluate a quantified disease reference set, using term frequency in phenotypic text descriptions to approximate term relevance. We demonstrate an improved ability to identify related diseases through the use of a quantified reference set, and that vector space similarity measures perform better than established information content based measures. These improvements enable the generation of bespoke virtual gene panels, facilitating more accurate and efficient interpretation of genomic variant profiles from individuals with rare Mendelian disorders. These methods are available online at https://atlas.genetics.kcl.ac.uk/~jake/cgi bin/patient_sim.py. PMID- 29460987 TI - MoCA for cognitive screening in Parkinson's disease: Beware of floor effect.

PMID- 29460989 TI - Attitudes toward adolescent self-harm and its prevention: The views of those who self-harm and their peers. AB - PROBLEM: Adolescent self-harm is a common phenomenon; however, little is known about young peoples' attitudes toward self-harm and what they believe can be done to prevent it. This study aimed to identify adolescents' attitudes about self harm and their perspectives on preventing it. METHODS: A cross-sectional anonymous survey was administered to 856 post-primary school students across 11 schools in Dublin, Ireland. Attitudes toward self-harm were captured through a five-item scale and views on prevention of self-harm were captured through an open-ended survey question. Responses from those who self-harmed and those who did not were compared to identify differences. FINDINGS: Significant differences were identified between those who self-harmed and their peers. Those who self harmed were less likely to believe that self-harm was carried out to get attention or was a result of loneliness or depression; they were more likely to believe that self-harm was impulsive. Findings demonstrated that a majority of young people believed that self-harm could be prevented and a number of preventative strategies were identified. CONCLUSIONS: It is important that the views of adolescents are incorporated into the design and delivery of youth friendly services and that there is a focus on increasing awareness of the youth orientated services that currently exist.

AB - The cerebellum displays various sorts of rhythmic activities covering both low- and high-frequency oscillations. These cerebellar high-frequency oscillations were observed in the cerebellar cortex. Here, we hypothesised that not only is the cerebellar cortex a generator of high-frequency oscillations but also that the deep cerebellar nuclei may also play a similar role. Thus, we analysed local field potentials and single-unit activities in the deep cerebellar nuclei before, during and after electric stimulation in the inferior olive of awake mice. A high frequency oscillation of 350 Hz triggered by the stimulation of the inferior olive, within the beta-gamma range, was observed in the deep cerebellar nuclei. The amplitude and frequency of the oscillation were independent of the frequency of stimulation. This oscillation emerged during the period of stimulation and persisted after the end of the stimulation. The oscillation coincided with the inhibition of deep cerebellar neurons. As the inhibition of the deep cerebellar nuclei is related to inhibitory inputs from Purkinje cells, we speculate that the oscillation represents the unmasking of the synchronous activation of another subtype of deep cerebellar neuronal subtype, devoid of GABA receptors and under the direct control of the climbing fibres from the inferior olive. Still, the mechanism sustaining this oscillation remains to be deciphered. Our study sheds new light on the role of the olivo-cerebellar loop as the final output control of the intercerebellar circuitry.

AB - OBJECTIVE: To describe the trends and occupational variation in the incidence of testicular cancer in the Nordic countries utilising national cancer registries, NORDCAN (NORDCAN project/database presents the incidence, mortality, prevalence and survival from >50 cancers in the Nordic countries) and NOCCA (Nordic Occupational Cancer) databases. PATIENTS AND METHODS: We obtained the incidence data of testicular cancer for 5-year periods from 1960-1964 to 2000-2014 and for 5-year age-groups from the NORDCAN database. Morphological data on incident cases of seminoma and non-seminoma were obtained from national cancer registries. Age standardised incidence rates (ASR) were calculated per 100 000 person-years (World Standard). Regression analysis was used to evaluate the annual change in the incidence of testicular cancer in each of the Nordic countries. The risk of testicular cancer in different professions was described based on NOCCA information and expressed as standardised incidence ratios (SIRs). RESULTS: During 2010-2014 the ASR for testicular cancer varied from 11.3 in Norway to 5.8 in Finland. Until 1998, the incidence was highest in Denmark. There has not been an increase in Denmark and Iceland since the 1990s, whilst the incidence is still strongly increasing in Norway, Sweden, and Finland. There were no remarkable changes in the ratio of seminoma and non-seminoma incidences during the past 50 years. There was no increase in the incidences in children and those of pension age. The highest significant excess risks of testicular seminoma were found in physicians (SIR 1.48, 95% confidence interval [CI] 1.07-1.99), artistic workers (SIR 1.47, 95% CI 1.06-1.99) and religious workers etc. (SIR 1.33, 95% CI 1.14 1.56). The lowest SIRs of testicular seminoma were seen amongst cooks and stewards (SIR 0.56, 95% CI 0.29-0.98), and forestry workers (SIR 0.64, 95% CI 0.47-0.86). The occupational category of administrators was the only one with a significantly elevated SIR for testicular non-seminoma (SIR 1.21, 95% CI 1.04 1.42). The only SIRs significantly <1.0 were seen amongst engine operators (SIR 0.60, 95% CI 0.41-0.84) and public safety workers (SIR 0.67, 95% CI 0.43-0.99). CONCLUSIONS: There have always been differences in the incidence of testicular cancer between the Nordic countries. There is also some divergence in the incidences in different age groups and in the trends of the incidence. The effect of occupation-related factors on incidence of testicular cancer is only moderate. Our study describes the differences, but provides no explanation for this variation. PMID- 29460992 TI - Formation Mechanism of Atmospheric Ammonium Bisulfate: Hydrogen-Bond-Promoted Nearly Barrierless Reactions of SO3 with NH3 and H2 O. AB - Particulate matter (PM) air pollution threatens the health of people and ecosystems worldwide. As the key component of PM, ammonium sulfate plays a critical role in the formation of aerosol particles; thus, there is an urgent need to know the detailed mechanisms for its formation in the atmosphere. Through a quantum chemistry study, we reveal a series of nearly barrierless reactions that may occur in clusters/droplets in the atmosphere leading to the formation of ammonium bisulfate (NH4 HSO4 ), the precursor of ammonium sulfate. In this mechanism, NH4 HSO4 is directly formed through one-step reactions of SO3 with H2 O and NH3 promoted by surrounding molecule(s) that substantially lower the reaction activation barrier to ~0 kcal mol-1 . The promoters of these reactions are found to be various common atmospheric molecules, such as water, ammonia, and sulfuric acid, which can form relatively strong hydrogen bonds with the reaction center. Our results suggest many more similar pathways that can be facilitated by other ambient molecules. Due to its one-step and barrierless reaction characteristics and the great abundance of potential reactions, this mechanism has great implications on the formation of atmospheric ammonium sulfate as well as on the growth of aerosol particles.

AB - On-surface synthesis shows significant potential in constructing novel nanostructures/nanomaterials, which has been intensely studied in recent years. The formation of acetylenic scaffolds provides an important route to the fabrication of emerging carbon nanostructures, including carbyne, graphyne, and graphdiyne, which feature chemically vulnerable sp-hybridized carbon atoms. Herein, we designed and synthesized a tribromomethyl-substituted compound. By using a combination of high-resolution scanning tunneling microscopy, non-contact atomic force microscopy, and density functional theory calculations, we demonstrated that it is feasible to convert these compounds directly into C-C triple-bonded structural motifs by on-surface dehalogenative homocoupling reactions. Concurrently, sp3 -hybridized carbon atoms are converted into sp hybridized ones, that is, an alkyl group is transformed into an alkynyl moiety. Moreover, we achieved the formation of dimer structures, one-dimensional molecular wires, and two-dimensional molecular networks on Au(111) surfaces, which should inspire further studies towards two-dimensional graphyne structures. PMID- 29460994 TI - Sexual habits of men with ED who take phosphodiesterase 5 inhibitors: a survey conducted in 7 countries. AB - INTRODUCTION: Western cultural perceptions that favour spontaneous sex may create unrealistic expectations for erectile dysfunction (ED) treatment. Little is known about how users of phosphodiesterase type 5 inhibitors (PDE5Is) plan sexual activity and timing of their preactivity PDE5I ingestion. Because various PDE5Is vary in their duration of action and dosage regimen, this may be an important consideration in selecting the optimal agent for the ED patient. AIM: To better understand the sexual habits of PDE5I users. METHODS: Men from 7 countries (Brazil, China, Italy, Japan, Russia, Taiwan, Turkey) were screened online for age, self-reported comorbidities and ED medication use in the prior 3 months. After screening, eligible participants were asked to complete a 7-question, self administered online survey containing questions regarding sexual habits and behaviours. MAIN OUTCOME MEASURES: Survey questions focused primarily on advanced planning of sexual intercourse and timing of PDE5I ingestion but also addressed the frequency of sexual intercourse and ED medication use. RESULTS: Of the 1458 respondents (response rate: 48%; median age: 48 years [interquartile range (IQR), 44-55]), 83% always/sometimes planned a specific time for intercourse in advance; 72% planned a specific time for sexual intercourse up to several hours in advance. Of respondents who planned in advance, more than half planned specific days of the week (55%) and times of the day (60%) for sexual intercourse. The time to sexual intercourse after dosing was <=1 hour for 70% and <=4 hours for 96% of men. The median frequency of sexual intercourse was 6 times/month (IQR, 4 10), with ED medication taken a median of 5 times/month (IQR, 3-8). CONCLUSIONS: Sexual activity is usually planned by ED medication users several hours in advance, and the vast majority are attempting activity within a short time after ingestion of the agent. These data should aid clinicians in the selection of the optimal PDE5I. PMID- 29460996 TI - Fluorine-Mediated Editing of a G-Quadruplex Folding Pathway. AB - A (3+1)-hybrid-type G-quadruplex was substituted within its central tetrad by a single 2'-fluoro-modified guanosine. Driven by the anti-favoring nucleoside analogue, a novel quadruplex fold with inversion of a single G-tract and conversion of a propeller loop into a lateral loop emerges. In addition, scalar couplings across hydrogen bonds demonstrate the formation of intra- and inter residual F???H8-C8 pseudo-hydrogen bonds within the modified quadruplexes. Alternative folding can be rationalized by the impact of fluorine on intermediate species on the basis of a kinetic partitioning mechanism. Apparently, chemical or other environmental perturbations are able to redirect folding of a quadruplex, possibly modulating its regulatory role in physiological processes.

AB - AIM: Quality of life (QoL) and functional outcomes are at risk of being impaired after rectal surgery, but there has been no large prospective study to thoroughly assess QoL according to surgical approach. We have investigated the impact of laparoscopic and robotic total mesorectal excision (TME) on QoL and functional outcomes. METHOD: Patients undergoing laparoscopic or robotic TME for rectal cancer between 2009 and 2013 were prospectively included in this questionnaire based survey of QoL together with variations in urinary and sexual function. A propensity score analysis was retrospectively conducted to compare outcomes between groups in a cohort matched 1:1 for age, sex, body mass index, preoperative chemoradiation status and tumour height. The survey was performed preoperatively and 3, 6 and 12 months after surgery. RESULTS: Global health status/QoL was similar between the two groups for 130 matched pairs, but the robotic group showed better role, emotional and social functioning and experienced less fatigue and financial difficulty. International Prostatic Symptom Scores in men increased postoperatively, with significantly less impairment in the robotic group at 6 months. These scores were comparable to preoperative scores at 6 months in the robotic group and at 12 months in the laparoscopic group. Of 48 sexually active men in each group, International Index of Erectile Function-5 scores decreased postoperatively, returning to preoperative levels at 6 months in the robotic group and at 12 months in the laparoscopic groups. CONCLUSION: The robotic approach for TME was associated with less impairment of urinary and sexual function; QoL was comparable to the laparoscopic approach. PMID- 29460998 TI - Corrigendum.

AB - Although the spliceogenic nature of the BRCA2 c.68-7T > A variant has been demonstrated, its association with cancer risk remains controversial. In this study, we accurately quantified by real-time PCR and digital PCR (dPCR), the BRCA2 isoforms retaining or missing exon 3. In addition, the combined odds ratio for causality of the variant was estimated using genetic and clinical data, and its associated cancer risk was estimated by case-control analysis in 83,636 individuals. Co-occurrence in trans with pathogenic BRCA2 variants was assessed in 5,382 families. Exon 3 exclusion rate was 4.5-fold higher in variant carriers (13%) than controls (3%), indicating an exclusion rate for the c.68-7T > A allele of approximately 20%. The posterior probability of pathogenicity was 7.44 * 10 115 . There was neither evidence for increased risk of breast cancer (OR 1.03; 95% CI 0.86-1.24) nor for a deleterious effect of the variant when co-occurring with pathogenic variants. Our data provide for the first time robust evidence of the nonpathogenicity of the BRCA2 c.68-7T > A. Genetic and quantitative transcript analyses together inform the threshold for the ratio between functional and altered BRCA2 isoforms compatible with normal cell function. These findings might be exploited to assess the relevance for cancer risk of other BRCA2 spliceogenic variants.

AB - OBJECTIVE: To estimate the prevalence of ocular disease and obtain normative ocular data for free-living hummingbirds. ANIMALS STUDIED: Two hundred and sixty three free-living, adult Hummingbirds from coastal and inland central California were studied, including Anna's (Calypte anna, n = 186) and Black-chinned (Archilochus alexandri; n = 77) hummingbirds. PROCEDURES: Slit lamp biomicroscopy and indirect ophthalmoscopy were performed on all individuals. Rebound tonometry, measurement of horizontal palpebral fissure length, and streak retinoscopy were performed on select individuals. Five conscious Anna's Hummingbirds underwent ocular imaging including fundus photography, digital slit lamp photography, and anterior segment and retinal optical coherence tomography. RESULTS: The prevalence of ocular disease in this population was 2.28%. Ocular imaging revealed a thin cornea, shallow anterior chamber, large lens, and a single central, deep convexiclivate fovea. Mean +/- SD intraocular pressure was 11.21 +/ 2.23 mm Hg. Mean +/- SD eyelid length was 2.59 +/- 0.19 mm. All eyes were emmetropic or mildly hyperopic with a mean (range) +/- SD refractive error of +0.32 (-0.25 to +1) +/- 0.33 diopters. CONCLUSIONS: Consistent with previous reports, these data suggest that hummingbirds have visual characteristics found in predatory and prey species, as well as a low prevalence of spontaneous ocular disease. This work provides a set of reference values and clinical findings that can be used in the future research on hummingbird vision and ocular disease. It also provides representative diagnostic images of normal birds and demonstrates that advanced ocular imaging can be performed on manually restrained hummingbirds without pharmacologic dilation.

AB - INTRODUCTION: The use of pre-analytical heat treatment (PHT) with the Nijmegen Bethesda assay (NBA) for inhibitors to factor VIII (FVIII) can remove/destroy infused or endogenous FVIII from patient plasma samples, allowing testing of recently infused patients with haemophilia. Two PHT methods have been described as follows: heating to 56 degrees C for 30 minutes and heating to 58 degrees C for 90 minutes. Data examining the effects of PHT on anti-FVIII IgG4 , the antibodies known to correlate most closely with the presence of FVIII inhibitors, are limited. AIM: To assess the effect of PHT on the levels of detectable anti FVIII IgG4 . METHODS: Nijmegen-Bethesda assay-positive specimens were incubated at 56, 58 or 60 degrees C for 90 minutes, and anti-FVIII IgG4 was measured by fluorescence immunoassay (FLI) at 30-minute intervals. The effects of PHT on the ability of recombinant FVIII (rFVIII) to inhibit detection of patient antibodies by FLI was also examined to assess the stability of rFVIII under the various PHT conditions tested. RESULTS: Levels of anti-FVIII IgG4 showed little change following incubations at 56 degrees C (mean 101% of original value at 30 minutes and 100% at 60 minutes) but decreased upon exposure to 58 degrees C (mean 85% at 30 minutes and 66% at 60 minutes). In addition, heating to 56 degrees C effectively decreased the ability of rFVIII to block antibody binding compared to unheated rFVIII. CONCLUSION: The optimal temperature for PHT in the FVIII NBA is 56 degrees C. Higher temperatures may lead to loss of inhibitory antibodies. PMID- 29461006 TI - Left ventricular geometric patterns in end-stage kidney disease: Determinants and course over time. AB - INTRODUCTION: While concentric left ventricular hypertrophy (cLVH) predominates in non-dialysis-dependent chronic kidney disease (CKD), eccentric left ventricular hypertrophy (eLVH) is most prevalent in dialysis-dependent CKD stage 5 (CKD5D). In these patients, the risk of sudden death is 5* higher than in individuals with cLVH. Currently, it is unknown which factors determine left ventricular (LV) geometry and how it changes over time in CKD5D. METHODS: Data from participants of the CONvective TRAnsport Study who underwent serial transthoracic echocardiography were used. Based on left ventricular mass (LVM) and relative wall thickness (RWT), 4 types of left ventricular geometry were distinguished: normal, concentric remodeling, eLVH, and cLVH. Determinants of eLVH were assessed with logistic regression. Left ventricular geometry of patients who died and survived were compared. Long-term changes in RWT and LVM were evaluated with a linear mixed model. FINDINGS: Three hundred twenty-two patients (63.1 +/- 13.3 years) were included. At baseline, LVH was present in 71% (cLVH: 27%; eLVH: 44%). Prior cardiovascular disease (CVD) was positively associated with eLVH and beta-blocker use inversely. None of the putative volume parameters showed any relationship with eLVH. Although eLVH was most prevalent in non-survivors, the distribution of left ventricular geometry did not vary over time. DISCUSSION: The finding that previous CVD was positively associated with eLVH may result from the permanent high cardiac output and the strong tendency for aortic valve calcification in this group of long-term hemodialysis patients, who suffer generally also from chronic anemia and various other metabolic derangements. No association was found between eLVH and parameters of fluid balance. The distribution of left ventricular geometry did not alter over time. The assumption that LV geometry worsens over time in susceptible individuals, who then suffer from a high risk of dying, may explain these findings.

AB - Dysfunction of arteriovenous access for hemodialysis is a challenge for the vascular surgeon. Some patients have complex vascular access with problems that are difficult to solve. Careful analysis of the vascular network with ultrasound and dissection of the veins during surgery can help to identify the best option for each access.

This technique enables extending fistula patency, arterializing the brachial vein, and improves cost efficiency. PMID- 29461008 TI - Propofol exposure during early gestation impairs learning and memory in rat offspring by inhibiting the acetylation of histone. AB - Propofol is widely used in clinical practice, including non-obstetric surgery in pregnant women. Previously, we found that propofol anaesthesia in maternal rats during the third trimester (E18) caused learning and memory impairment to the offspring rats, but how about the exposure during early pregnancy and the underlying mechanisms? Histone acetylation plays an important role in synaptic plasticity. In this study, propofol was administered to the pregnant rats in the early pregnancy (E7). The learning and memory function of the offspring were tested by Morris water maze (MWM) test on post-natal day 30. Two hours before each MWM trial, histone deacetylase 2 (HDAC2) inhibitor, suberoylanilide hydroxamic acid (SAHA), Senegenin (SEN, traditional Chinese medicine), hippyragranin (HGN) antisense oligonucleotide (HGNA) or vehicle were given to the offspring. The protein levels of HDAC2, acetylated histone 3 (H3) and 4 (H4), cyclic adenosine monophosphate (cAMP) response element-binding protein (CREB), N methyl-D-aspartate receptor (NMDAR) 2 subunit B (NR2B), HGN and synaptophysin in offspring's hippocampus were determined by Western blot or immunofluorescence test. It was discovered that infusion with propofol in maternal rats on E7 leads to impairment of learning and memory in offspring, increased the protein levels of HDAC2 and HGN, decreased the levels of acetylated H3 and H4 and phosphorylated CREB, NR2B and synaptophysin. HDAC2 inhibitor SAHA, Senegenin or HGN antisense oligonucleotide reversed all the changes. Thus, present results indicate exposure to propofol during the early gestation impairs offspring's learning and memory via inhibiting histone acetylation. SAHA, Senegenin and HGN antisense oligonucleotide might have therapeutic value for the adverse effect of propofol. PMID- 29461009 TI - Metabolomic responses to lumacaftor/ivacaftor in cystic fibrosis. AB - BACKGROUND: Cystic fibrosis (CF) is a life-limiting disease caused by a defect in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. Lumacaftor/Ivacaftor is a novel CFTR modulator approved for patients that are homozygous for Phe508del CFTR, but its clinical effectiveness varies amongst patients, making it difficult to determine clinical responders. Therefore, identifying biochemical biomarkers associated with drug response are clinically important for follow-up studies. METHODS: Serum metabolomics was performed on twenty patients with CF pre- and 6-month post-Lumacaftor/Ivacaftor response via Ultrahigh Performance Liquid Chromatography-Tandem Mass Spectroscopy (UPLC MS/MS). Correlation with clinical variables was performed. RESULTS: Metabolomics analysis demonstrated 188 differentially regulated metabolites between patients pre- and post-Lumacaftor/Ivacaftor initiation, with a predominance of lipid and amino acid alterations. The top 30 metabolites were able to differentiate pre- and post-Lumacaftor/Ivacaftor status in greater than 90% of patients via a random forest confusion matrix. Alterations in bile acids, phospholipids, and bacteria associated metabolites were the predominant changes associated with drug response. Importantly, changes in metabolic patterns were associated with clinical responders. CONCLUSIONS: Selected key lipid and amino acid metabolic pathways were significantly affected by Lumacaftor/Ivacaftor initiation and similar pathways were affected in clinical responders. Targeted metabolomics may provide useful and relevant biomarkers of CFTR modulator responses.

AB - From June to July 2017, six Seneca Valley virus (SVV) strains were isolated from swine herds exhibiting SVV-associated porcine idiopathic vesicular disease (PIVD) in Guangdong province, China. Complete genomic sequences of these six newly identified strains were genetically and phylogenetically analysed. The results revealed that these six SVV strains were genetically closely related to USA/GBI29/2015 and notably distinct from all previous Chinese strains, indicating the reemergence of new SVV strains in Guangdong province.

The quantity of drug required for a LDDS is much smaller than that needed for systemic chemotherapy. However, the relationship between the rate of drug injection into a SLN and the amount of drug reaching the secondary LNs has not been investigated. In this study, we used an MXH10/Mo-lpr/lpr mouse model to show that the optimal rate for the injection of a fluorescent dye by a LDDS was 10 to 80 MUL/min. An injection rate of 10 to 80 MUL/min was able to fill the downstream LN. However, an injection rate of 100 MUL/min drove the fluorescent dye into the efferent lymphatic vessels and thoracoepigastric vein, decreasing the amount of dye retained in the downstream LN. Bolus injection (defined as an injection rate of 2400 MUL/min) was unable to deliver fluorescent dye into the downstream LN. These results agree with the impulse values calculated from the injection pressures in the upstream LN. We anticipate that our findings will facilitate the development of a LDDS for use in the clinic.

AB - INTRODUCTION: Most patients take time to recover after a hemodialysis (HD) session. It has been suggested that recovery time is associated with intradialytic hypotension and rapid solute clearances. Other studies have reported a linkage to depression. We investigated the association between recovery time and intradialytic hypotension and depression. METHODS: In five UK HD units, we screened for depressive symptoms using the Beck depression inventory II, Patient Health Questionnaire, and recorded sessional blood pressures and Kt/Vurea. FINDINGS: Seven hundred and one HD patients were studied; 63.6% male, mean age 64.1 +/- 16.6 years, 33.5% diabetic. About 24.1% recovered in <1 hour, 27% 1-4 hours, 15.4% 4-8 hours, 10.7% 8-12 hours, and 22.8% after 12 hours. Systolic blood pressure fell by >=20 mmHg in 30.9% postdialysis, and to <100 mmHg in 7.6%. In multivariate analysis, patients with recovery times >1 hour were more likely to be female, have high self-reported Beck depression inventory-II scores, a past medical history of depression, and be living without a partner. Longer recovery times were also associated with very low postdialysis systolic blood pressures (<100 mmHg), and higher body weight. However, the model predicted only 18% of the variation in recovery times. We found no association between recovery times and short-term mortality risk. DISCUSSION: Prolonged postdialysis recovery times are associated with higher self-reported depression scores, and very low postdialysis blood pressure. Future studies investigating changes in dialysis practice and recovery times will need to target strategies to prevent intradialytic hypotension and adjust for patient psychological status.

AB - OBJECTIVE: To provide a systematic review of correlates of adherence to inhaled corticosteroids (ICS) in pediatric asthma across the individual, family, community, and healthcare system domains. METHODS: Articles assessing medication adherence in pediatric asthma published from 1997 to 2016 were identified using PsychINFO, Medline, and CINAHL. Search terms included asthma, compliance, self management, adherence, child, and youth. Search results were limited to articles: 1) published in the US; 2) using a pediatric population (0-25 years old); and 3) presenting original data related to ICS adherence. Correlates of adherence were categorized according to the domains of the Pediatric Self-Management Model. Each article was evaluated for study quality. RESULTS: Seventy-nine articles were included in the review. Family-level correlates were most commonly reported (N = 51) and included socioeconomic status, race/ethnicity, health behaviors, and asthma knowledge. Individual-level correlates were second-most common (N = 37), with age being the most frequently identified negative correlate of adherence. Health care system correlates (N = 24) included enhanced asthma care and patient provider communication. Few studies (N = 10) examined community correlates of adherence. Overall study quality was moderate, with few quantitative articles (26.38%) and qualitative articles (21.4%) referencing a theoretical basis for their studies. CONCLUSIONS: All Pediatric Self-Management Model domains were correlated with youth adherence, which suggests medication adherence is influenced across multiple systems; however, most studies assessed adherence correlates within a single domain. Future research is needed that cuts across multiple domains to advance understanding of determinants of adherence.

AB - New psychoactive substances represent serious social and health problem as tens of new compounds are detected in Europe annually. They often show structural proximity or even isomerism, which complicates their analysis. Two methods based on ultra high performance supercritical fluid chromatography and ultra high performance liquid chromatography with mass spectrometric detection were validated and compared. A simple dilute-filter-and-shoot protocol utilizing propan-2-ol or methanol for supercritical fluid or liquid chromatography, respectively, was proposed to detect and quantify 15 cathinones and phenethylamines in human urine. Both methods offered fast separation (<3 min) and short total analysis time. Precision was well <15% with a few exceptions in liquid chromatography. Limits of detection in urine ranged from 0.01 to 2.3 ng/mL, except for cathinone (5 ng/mL) in supercritical fluid chromatography. Nevertheless, this technique distinguished all analytes including four pairs of isomers, while liquid chromatography was unable to resolve fluoromethcathinone regioisomers. Concerning matrix effects and recoveries, supercritical fluid chromatography produced more uniform results for different compounds and at different concentration levels. This work demonstrates the performance and reliability of supercritical fluid chromatography and corroborates its applicability as an alternative tool for analysis of new psychoactive substances in biological matrixes.

AB - OBJECTIVE: Childhood asthma is a chronic inflammatory airway disorder with increasing prevalence even in Africa. Vitamin D, with anti-inflammatory and immune-modulatory properties, may have effects on the severity and level of symptoms control in childhood asthma. We aimed to assess the serum vitamin D levels in children with asthma as related to disease severity and control in a tropical region. METHODS: A hospital based comparative cross sectional study was conducted in western Nigeria. Serum vitamin D (25-OH-D) levels of all the children, assayed using high-performance liquid chromatography (HPLC), were compared to the various disease severity and levels of asthma control as well as between the asthmatic and non-asthmatic children. RESULTS: A total of 206 children (103 asthmatics and 103 non-asthmatics) were recruited with a mean (SD) age of 6.6 (3.7) years. The majority (82.5%) of the children with asthma had mild intermittent form, 63.1% had well controlled symptoms while 33.0% and 3.9% had partly controlled and uncontrolled symptoms, respectively. None of the children were deficient in vitamin D. The mean (SD) serum vitamin D levels of the children with asthma (49.2 [7.2] ng/mL) was significantly lower than those without asthma (51.2 [6.9] ng/mL, P = 0.043). Varying degrees of asthma severity and levels of symptoms control were not affected by serum vitamin D levels. CONCLUSION: Children with asthma in Nigeria had marginally but significantly lower mean serum vitamin D levels when compared with their counterparts without asthma. However, serum vitamin D level does not seem to be associated with childhood asthma severity and control in these children with normal serum vitamin D levels.

AB - Respiratory syncytial virus (RSV), responsible for more than three million yearly hospitalizations and up to 118 000 deaths in children under 5 years, is the leading pulmonary cause of death for this age group that lacks a licensed vaccine. Ninety-nine percent of deaths due to the virus occur in developing countries. In-hospital RSV fatalities affect previously healthy term infants in association with bacterial sepsis, clinically significant pneumothoraxes and, to a lesser extent, comorbid conditions. Community deaths affect low-income children from socially vulnerable families and appear to be as frequent as inpatient fatalities. In industrialized countries, RSV deaths occur almost exclusively in children with premorbid conditions. In a sense, RSV is an "opportunistic" killer. It needs a synergistic premorbid, medical practice-related, infectious, or social co-factor to cause a fatal outcome. But while the complex problems associated with these co-factors await solutions, candidate vaccines, long-lived monoclonal antibodies and antivirals against RSV are under clinical evaluation. It seems reasonable to predict that the landscape of RSV infections will look different in the next decade.

Extension of temporary moratoria. AB - This document announces the extension of statewide temporary moratoria on the enrollment of new Medicare Part B non-emergency ground ambulance providers and suppliers and Medicare home health agencies, subunits, and branch locations in Florida, Illinois, Michigan, Texas, Pennsylvania, and New Jersey, as applicable, to prevent and combat fraud, waste, and abuse. This extension also applies to the enrollment of new non-emergency ground ambulance suppliers and home health agencies, subunits, and branch locations in Medicaid and the Children's Health Insurance Program in those states. For purposes of these moratoria, providers that were participating as network providers in one or more Medicaid managed care organizations prior to January 1, 2018 will not be considered "newly enrolling" when they are required to enroll with the State Medicaid agency pursuant to a new statutory requirement, and thus will not be subject to the moratoria.

PMID- 29461025 TI - Older Californians and the Mental Health Services Act: Is an Older Adult System of Care Supported? AB - This policy brief summarizes findings from the first study to evaluate how California's public mental health delivery system has served older adults (60 years of age and over) since the passage of the Mental Health Services Act (MHSA) in 2004. Study findings indicate that there are unmet needs among older adults with mental illness in the public mental health delivery system. There are deficits in the involvement of older adults in the required MHSA planning processes and in outreach and service delivery, workforce development, and outcomes measurement and reporting. There is also evidence of promising programs and strategies that counties have advanced to address these deficits. Recommendations for improving mental health services for older adults include designating a distinct administrative and leadership structure for older adult services in each county; enhancing older adult outreach and documentation of unmet need; promoting standardized geriatric training of providers; instituting standardized data-reporting requirements; and increasing service integration efforts, especially between medical, behavioral health, aging, and substance use disorder services. PMID- 29461026 TI - Mental Health Services for Older Adults: Creating a System That Tells the Story. AB - In 2004, voters in California approved Proposition 63 for passage of the Mental Health Services Act (MHSA). From thattime until 2014, over $13 billion in the state's tax revenue was allocated for public mental health services. There is very little information available to answer critical questions such as these: How much of this amount was spent in the interests of older adult mental health? What benefits were gained from services delivered to older adults? This policy brief promotes recommendations for specific age-relevant indicator utilization and for an expanded system of uniform and transparent data for all types of MHSA-funded programs. These two policy directions are necessary in order to document the older adult mental health care services provided and to track outcomes at the state level for MHSA programs. A third recommendation centers on assuring that the mental health workforce is prepared to utilize and report age-relevant data indicators. PMID- 29461027 TI - [Effect of forest management on the herpetofauna of a temperate forest of western Oaxaca, Mexico]. AB - The development of silvicultural techniques has as main objective to maximize the production of timber, whereas at the same time minimize the impact generated during and after forest intervention in the local diversity. However, these activities change local climate, and this, in turn, alter the composition of natural communities. The effect of these changes may be greater in those taxonomic groups with high sensitivity to habitat disturbance, such as amphibians and reptiles, which are the unique terrestrial ectothermic vertebrates. The present study aims to know the differences in diversity of amphibians and reptiles in a temperate forest under two silvicultural treatments, one of low and the other of high intensity, as well as from one, five and ten years of regeneration since the last logging event, Sierra Sur of Oaxaca, Mexico. Records of 21 species of herpetofauna (six amphibians and 15 reptiles) were obtained. The total species richness was similar in both treatments; however, the composition varied between sites with different recovery times. Higher abundance of amphibian was presented on sites with the low-intensity treatment, while reptiles were more abundant at sites with intensive treatment. Compared to a mature forest without management, sites with intensive treatment have more rare species, although the values of true diversity of amphibians were similar between treatments with different intensities, while for reptiles sites under treatment showed less diversity that unmanaged site: 33 % for intensive treatment and 28 % at sites with low intensity with respect to one control site. Complementary Analysis showed a difference of 86 % between the compositions of species in sites with intensive treatment. The treatment intensity was associated with an increase in the number of species, but the way they respond to changes in habitat depends largely on the population characteristics of each species and its ability to adapt to new conditions. PMID- 29461028 TI - Dung removal by dung beetles (Coleoptera: Scarabaeidae) and macrocyclic lactone use on cattle ranches of Yucatan, Mexico. AB - The expanded use of macrocyclic lactones (ML) to treat endo- and ectoparasites in cattle in tropical regions, can reduce dung beetle populations, and thus interrupt the dung removal process in cattle pasture ecosystems. During the reproductive period (the rainy season) of two functional groups of dung beetles (paracoprid and telocoprid Scarabaeinae), we compared dung removal amount in ranches where ML are and are not used in Yucatan, Mexico, through exclusion traps baited with 500 g of ML-free cow dung. On each ranch, two transects (separated by 500 m) with six traps each, were set up for 24 hours. After this time, all the dung remnants in each trap were obtained and weighed in order to record the dung removal. Results showed that dung removal amounts were similar in ranches with and without ML use. Dung beetles removed 40.1 % of all cow dung weighed. Paracoprids removed 87.46 % and telocoprids 12.54 % of all the dung that was removed. Our results indicated that the ecological function of dung beetles in the pastures studied, does not seem to be affected by the ML use, and that paracoprid species removed most of the dung. For both types of ranch, further studies that take into account the population dynamics and movement of the most important dung beetle species in the region are required, coupled with laboratory studies evaluating the effect of ML on their reproductive success. This could give some light on the effect of ML on the ecological function of this important insect group in the sustainability of cattle production systems. PMID- 29461029 TI - Molecular Sieve Induced Solution Growth of Li2O2 in the Li-O2 Battery with Largely Enhanced Discharge Capacity. AB - The formation of the insulated film-like discharge products (Li2O2) on the surface of the carbon cathode gradually hinders the oxygen reduction reaction (ORR) process, which usually leads to the premature death of the Li-O2 battery. In this work, by introducing the molecular sieve powder into the ether electrolyte, the Li-O2 battery exhibits a largely improved discharge capacity (63 times) compared with the one in the absence of this inorganic oxide additive. Meanwhile, XRD and SEM results qualitatively demonstrate the generation of the toroid Li2O2 as the dominated discharge products, and the chemical titration quantifies a higher yield of the Li2O2 with the presence of the molecular sieve additive. The addition of the molecular sieve controls the amount of the free water in the electrolyte, which distinguishes the effect of the molecular sieve and the free water on the discharge process. Hence, a possible mechanism has been proposed that the adsorption of the molecular sieves toward the soluble lithium superoxides improves the disproportionation of the lithium superoxides and consequently enhances the solution-growth of the lithium peroxides in the low donor number ether electrolyte. In general, the application of the molecular sieve triggers further studies concerning the improvement of the discharge performance in the Li-O2 battery by adding the inorganic additives. PMID- 29461030 TI - Synthesis and Characterization of CuFe2O4 Nano/Submicron Wire-Carbon Nanotube Composites as Binder-free Anodes for Li-Ion Batteries. AB - A series of one-dimensional CuFe2O4 (CFO) nano/submicron wires possessing different diameters, crystal phases, and crystal sizes have been successfully generated using a facile template-assisted coprecipitation reaction at room temperature, followed by a short postannealing process. The diameter and crystal structure of the resulting CuFe2O4 (CFO) wires were judiciously tuned by varying the pore size of the template and the postannealing temperature, respectively. Carbon nanotubes (CNTs) were incorporated to generate CFO-CNT binder-free anodes, and multiple characterization techniques were employed with the goal of delineating the relationships between electrochemical behavior and the properties of both the CFO wires (crystal phase, wire diameter, crystal size) and the electrode architecture (binder-free vs conventionally prepared approaches). The study reveals several notable findings. First, the crystal phase (cubic or tetragonal) did not influence the electrochemical behavior in this CFO system. Second, regarding crystallite size and wire diameter, CFO wires with larger crystallite sizes exhibit improved cycling stability, whereas wires possessing smaller diameters exhibit higher capacities. Finally, the electrochemical behavior is strongly influenced by the electrode architecture, with CFO-CNT binder-free electrodes demonstrating significantly higher capacities and cycling stability compared to conventionally prepared coatings. The mechanism(s) associated with the high capacities under low current density but limited electrochemical reversibility of CFO electrodes under high current density were probed via X-ray absorption spectroscopy mapping with submicron spatial resolution for the first time. Results suggest that the capacity of the binder free electrodes under high rate is limited by the irreversible formation of Cu0, as well as limited reduction of Fe3+ to Fe2+, not Fe0. The results (1) shed fundamental insight into the reversibility of CuFe2O4 materials cycled at high current density and (2) demonstrate that a synergistic effort to control both active material morphology and electrode architecture is an effective strategy for optimizing electrochemical behavior. PMID- 29461031 TI - Redox Additive-Improved Electrochemically and Structurally Robust Binder-Free Nickel Pyrophosphate Nanorods as Superior Cathode for Hybrid Supercapacitors. AB - For several decades, one of the great challenges for constructing a high-energy supercapacitor has been designing electrode materials with high performance. Herein, we report for the first time to our knowledge a novel hybrid supercapacitor composed of battery-type nickel pyrophosphate one-dimensional (1D) nanorods and capacitive-type N-doped reduced graphene oxide as the cathode and anode, respectively, in an aqueous redox-added electrolyte. More importantly, ex situ microscopic images of the nickel pyrophosphate 1D nanorods revealed that the presence of the battery-type redox additive enhanced the charge storage capacity and cycling life as a result of the microstructure stability. The nickel pyrophosphate 1D nanorods exhibited their maximum specific capacitance (8120 mF cm-2 at 5 mV s-1) and energy density (0.22 mWh cm-2 at a power density of 1.375 mW cm-2) in 1 M KOH + 75 mg K3[Fe(CN)6] electrolyte. On the other side, the N doped reduced graphene oxide delivered an excellent electrochemical performance, demonstrating that it was an appropriate anode. A hybrid supercapacitor showed a high specific capacitance (224 F g-1 at a current density of 1 A g-1) and high energy density (70 Wh kg-1 at a power density of 750 W kg-1), as well as a long cycle life (a Coulombic efficiency of 96% over 5000 cycles), which was a higher performance than most of those in recent reports. Our results suggested that the materials and redox additive in this novel design hold great promise for potential applications in a next-generation hybrid supercapacitor. PMID- 29461033 TI - >1000-Fold Lifetime Extension of a Nickel Electromechanical Contact Device via Graphene. AB - Micro-/nano-electromechanical (M/NEM) switches have received significant attention as promising switching devices for a wide range of applications such as computing, radio frequency communication, and power gating devices. However, M/NEM switches still suffer from unacceptably low reliability because of irreversible degradation at the contacting interfaces, hindering adoption in practical applications and further development. Here, we evaluate and verify graphene as a contact material for reliability-enhanced M/NEM switching devices. Atomic force microscopy experiments and quantum mechanics calculations reveal that energy-efficient mechanical contact-separation characteristics are achieved when a few layers of graphene are used as a contact material on a nickel surface, reducing the energy dissipation by 96.6% relative to that of a bare nickel surface. Importantly, graphene displays almost elastic contact-separation, indicating that little atomic-scale wear, including plastic deformation, fracture, and atomic attrition, is generated. We also develop a feasible fabrication method to demonstrate a MEM switch, which has high-quality graphene as the contact material, and verify that the devices with graphene show mechanically stable and elastic-like contact properties, consistent with our nanoscale contact experiment. The graphene coating extends the switch lifetime >103 times under hot switching conditions. PMID- 29461032 TI - Novel Cyclosilazane-Type Silicon Precursor and Two-Step Plasma for Plasma Enhanced Atomic Layer Deposition of Silicon Nitride. AB - We designed cyclosilazane-type silicon precursors and proposed a three-step plasma-enhanced atomic layer deposition (PEALD) process to prepare silicon nitride films with high quality and excellent step coverage. The cyclosilazane type precursor, 1,3-di-isopropylamino-2,4-dimethylcyclosilazane (CSN-2), has a closed ring structure for good thermal stability and high reactivity. CSN-2 showed thermal stability up to 450 degrees C and a sufficient vapor pressure of 4 Torr at 60 degrees C. The energy for the chemisorption of CSN-2 on the undercoordinated silicon nitride surface as calculated by density functional theory method was -7.38 eV. The PEALD process window was between 200 and 500 degrees C, with a growth rate of 0.43 A/cycle. The best film quality was obtained at 500 degrees C, with hydrogen impurity of ~7 atom %, oxygen impurity less than 2 atom %, low wet etching rate, and excellent step coverage of ~95%. At 300 degrees C and lower temperatures, the wet etching rate was high especially at the lower sidewall of the trench pattern. We introduced the three-step PEALD process to improve the film quality and the step coverage on the lower sidewall. The sequence of the three-step PEALD process consists of the CSN-2 feeding step, the NH3/N2 plasma step, and the N2 plasma step. The H radicals in NH3/N2 plasma efficiently remove the ligands from the precursor, and the N2 plasma after the NH3 plasma removes the surface hydrogen atoms to activate the adsorption of the precursor. The films deposited at 300 degrees C using the novel precursor and the three-step PEALD process showed a significantly improved step coverage of ~95% and an excellent wet etching resistance at the lower sidewall, which is only twice as high as that of the blanket film prepared by low-pressure chemical vapor deposition.

AB - CXC chemokine receptor 4 (CXCR4) is involved in multiple physiological and pathological processes, notably as a coreceptor for human immunodeficiency virus (HIV) cell entry. Its broad expression pattern and vital biological importance make CXCR4 a troublesome drug target, as disruption of the interaction with its endogenous ligand, CXC chemokine ligand 12 (CXCL12), has severe consequences. In fact, only one CXCR4 drug, the bicyclam antagonist and HIV entry inhibitor AMD3100 (Plerixafor/Mozobil), has been approved for clinical use, however only for stem cell mobilization-a consequence of CXCR4 antagonism. Here, we report the engineering of an efficacy switch mutation in CXCR4-F292A7.43 in the middle of transmembrane helix 7-that converted the antagonists AMD3100 and AMD11070 into partial agonists. As agonists on F292A CXCR4, AMD3100 and AMD11070 were less disruptive to CXCR4 signaling while they remained efficient inhibitors of HIV fusion. This demonstrates that small molecule CXCR4 agonists can have a therapeutic potential as HIV entry inhibitors. PMID- 29461036 TI - Patterning Multi-Nanostructured Poly(l-lactic acid) Fibrous Matrices to Manipulate Biomolecule Distribution and Functions. AB - Precise manipulation of biomolecule distribution and functions via biomolecule matrix interaction is very important and challenging for tissue engineering and regenerative medicine. As a well-known biomimetic matrix, electrospun fibers often lack the unique spatial complexity compared to their natural counterparts in vivo and thus cannot deliver fully the regulatory cues to biomolecules. In this paper, we report a facile and reliable method to fabricate micro- and nanostructured poly(l-lactic acid) (PLLA) fibrous matrices with spatial complexity by a combination of advanced electrospinning and agarose hydrogel stamp-based micropatterning. Specifically, advanced electrospinning is used to construct multi-nanostructures of fibrous matrices while solvent-loaded agarose hydrogel stamps are used to create microstructures. Compared with other methods, our method shows extreme simplicity and flexibility originated from the mono /multi-spinneret conversion and limitless micropatterns of agarose hydrogel stamps. Three types of PLLA fibrous matrices including patterned nano-Ag/PLLA hybrid fibers, patterned bicompartment polyethylene terephthalate/PLLA fibers, and patterned hollow PLLA fibers are fabricated and their capability to manipulate biomolecule distribution and functions, that is, bacterial distribution and antibacterial performance, cell patterning and adhesion/spreading behaviors, and protein adsorption and delivery, is demonstrated in detail. The method described in our paper provides a powerful tool to restore spatial complexity in biomimetic matrices and would have promising applications in the field of biomedical engineering. PMID- 29461035 TI - Heparin-Eluting Electrospun Nanofiber Yarns for Antithrombotic Vascular Sutures. AB - The surgical connection of blood vessels, anastomosis, is a critical procedure in many reparative, transplantation, and reconstructive surgical procedures. However, effective restoration of circulation is complicated by pathological clotting (thrombosis) or progressive occlusion due to excess cell proliferation that often leads to additional surgeries and increases morbidity and mortality risk for patients. Pharmaceutical agents have been tested to prevent these complications, but many have unacceptable systemic side effects. Therefore, an alternative approach to deliver these drugs at the site of injury in a controlled manner is necessary. The objective of this study was to develop electrospun nanofibers composed of polyester poly(lactide- co-glycolide) (PLGA), poly(ethylene oxide) (PEO), and positively charged copolymer, poly(lactide- co glycolide)- graft-polyethylenimine (PgP) for electrostatic binding and release of heparin for application as an antithrombotic microvascular suture. PgP was synthesized with different coupling ratios between PLGA and branched polyethylenimine (bPEI) to obtain PgP1 (~1 PLGA grafted to 1 bPEI) and PgP3.7 (~3.7 PLGA grafted to 1 bPEI). Nanofiber yarns (PLGA/PEO/PgP1 and PLGA/PEO/PgP3.7) were fabricated by electrospinning. Heparin immobilization on the positively charged nanofiber yarns was visualized using fluorescein conjugated heparin (F-Hep), and the amount of immobilized F-Hep was higher on both PLGA/PEO/PgP3.7 and PLGA/PEO/PgP1 than yarns without PgP (PLGA/PEO). We also found that F-Hep was released from both PgP-containing yarns in a sustained manner over 20 days, while over 60% of F-Hep was released within 4 h from PLGA/PEO. Finally, we observed that heparin-eluting nanofiber yarns with both PgP1 and PgP3.7 showed significantly longer clotting times than nanofiber yarns without PgP. The clotting time of PLGA/PEO/PgP3.7 was not significantly different than that of free heparin (0.5 MUg/mL). These results show that heparin-eluting electrospun nanofiber yarns may offer a basis for the development of microvascular sutures with anticoagulant activity.

AB - A new type of thermosensitive dual-template epitope molecular imprinting polymer was prepared and coated on magnetic carbon nanotubes (MCNTs@D-EMIP) for simultaneous recognition of human serum albumin (HSA) and transferrin (Trf) via the strategies of dual-template epitope imprinting, metal chelation imprinting, and distillation-precipitation polymerization (DPP). C-terminal peptides of HSA and C-terminal peptides of Trf were selected as templates, zinc acrylate and N isopropylacrylamide were used as functional monomers, and MCNTs@D-EMIP was prepared by the method of DPP. The two types of template epitopes were immobilized by metal chelation and six-membered ring formed with zinc acylate. MCNTs@D-EMIP was prepared in only 30 min, which was much shorter than other polymerization methods. The resultant MCNTs@D-EMIP showed excellent specific recognition ability toward HSA and Trf. The adsorption amounts of MCNTs@D-EMIP for HSA and Trf were 103.67 and 68.48 mg g-1 and the imprinting factors were 2.57 and 2.17, respectively. In addition, MCNTs@D-EMIP displayed a thermosensitive property to realize temperature-controlled recognition and release of target proteins. Furthermore, the results of high-performance liquid chromatography analysis proved that MCNTs@D-EMIP could be applied to specifically recognize two types of targets simultaneously in the biosample. The proposed strategy provided a preparation method for the thermosensitive dual-template epitope imprinting polymer via dual-template imprinting, metal chelation imprinting, and DPP. PMID- 29461038 TI - Portable Photoelectrochemical Device Integrated with Self-Powered Electrochromic Tablet for Visual Analysis. AB - A portable photoelectrochemical (PEC) device is developed by intergating a self powered electrochromic tablet for visual analysis. The tablet consists of an electron-injector (EI) part for photo-to-electric conversion and an electrochromic (EC) part for visualized readout, which are coated with dye sensitized titanium dioxide film and Ni-doped tungsten trioxide (WO3) film, respectively. Under the illumination of a white LED light, the photoexcited electrons generated from EI part convey to EC part through the conductive inner side of indium tin oxide slide and would cause color change of the Ni-doped WO3 film in the presence of protons. Furthermore, the Ni-doped WO3 film exhibits excellent transmittance modulation of more than 80%, providing an enhanced signal for visual analysis. Using pyrophosphate ion (PPi) as a model analyte, we have successfully constructed a visualized PEC sensing platform based on the formation of blue-colored hydrogen tungsten bronzes via the hydrolysis reaction of PPi. Being equipped with a small light source and a dark box, the PEC tablet as a portable device can perform colorimetric measurement with good reversibility and stability. This smart PEC device provides important reference for future studies on the visual application in practice. PMID- 29461039 TI - Dark Classics in Chemical Neuroscience: Lysergic Acid Diethylamide (LSD). AB - Lysergic acid diethylamide (LSD) is one of the most potent psychoactive agents known, producing dramatic alterations of consciousness after submilligram (>=20 MUg) oral doses. Following the accidental discovery of its potent psychoactive effects in 1943, it was supplied by Sandoz Laboratories as an experimental drug that might be useful as an adjunct for psychotherapy, or to give psychiatrists insight into the mental processes in their patients. The finding of serotonin in the mammalian brain in 1953, and its structural resemblance to LSD, quickly led to ideas that serotonin in the brain might be involved in mental disorders, initiating rapid research interest in the neurochemistry of serotonin. LSD proved to be physiologically very safe and nonaddictive, with a very low incidence of adverse events when used in controlled experiments. Widely hailed by psychiatry as a breakthrough in the 1950s and early 1960s, clinical research with LSD ended by about 1970, when it was formally placed into Schedule 1 of the Controlled Substances Act of 1970 following its growing popularity as a recreational drug. Within the past 5 years, clinical research with LSD has begun in Europe, but there has been none in the United States. LSD is proving to be a powerful tool to help understand brain dynamics when combined with modern brain imaging methods. It remains to be seen whether therapeutic value for LSD can be confirmed in controlled clinical trials, but promising results have been obtained in small pilot trials of depression, anxiety, and addictions using psilocybin, a related psychedelic molecule.

AB - Controlling graphene's doping will be critically important for its incorporation into future electronic and optoelectronic devices. Noncovalent functionalization through adsorption of organic molecules on graphene's surface has proved to be a promising route for achieving p- or n-type doping. However, due to the poor adhesion of the molecules, these tend to desorb over time under standard environmental conditions or in the presence of certain solvents. The resulting reversal in the achieved chemical doping is a major obstacle to using organic molecules as noncovalent graphene dopants. In this work, we present a simple method for achieving long-term p- and n-doping of graphene devices through vapor phase evaporation of organic molecules, followed by encapsulation under an inert Al2O3 film. This film, grown via an optimized atomic layer deposition process, ensures long-term doping stability, as confirmed by electrical transport and Raman spectroscopy measurements. The doping is maintained even after storing the devices for six weeks in ambient conditions and immersing them in a dopant removing solvent, demonstrating that the film is as an effective barrier against environmental degradation of the doped devices. PMID- 29461041 TI - Development of Graphene Oxide Composite Aerogel with Proanthocyanidins with Hemostatic Properties As a Delivery System. AB - The graphene aerogels' potential for use as both a hemostatic agent and dermal delivery system has scarcely been investigated. In this study, we used a sol-gel process for generating dry and stable composite aerogels based on graphene oxide (GO) and poly(vinyl alcohol) (PVA). Furthermore, we incorporated natural extract of Pais grape seed (SD) and skin (SK), rich in proanthocyanidins (PAs or condensed tannins). The effect of the incorporation of the grape extracts was investigated in relation to the aerogels' structure, coagulation performance and the release of the extracts. The results demonstrated that they have a porous structure and low density, capable of absorbing water and blood. The incorporation of 12% (w/w) of PA extracts into the aerogel increased the negative zeta potential of the material by 33% (-18.3 +/- 1.3 mV), and the coagulation time was reduced by 37% and 28% during the first 30 and 60 s of contact between the aerogel and whole blood, respectively. The release of extracts from the GO PVA-SD and GO-PVA-SK aerogels was prolonged to 3 h with 20%, probably due to the existence of strong binding between PAs andGO-PVA, both characterized by the presence of aromatic and hydroxyl groups that can form noncovalent bonds but are strong and stable enough to avoid a greater release into the medium. This study provides a new GO-based aerogel, which has a great potential use in the field of dermal delivery, wound healing and/or the treatment of trauma bleeding. PMID- 29461042 TI - Rational Design of Magnetic Micronanoelectrodes for Recognition and Ultrasensitive Quantification of Cysteine Enantiomers. AB - Driven by the urgent need for recognition and quantification of trace amino acids enantiomers in various biologic samples, we demonstrate for the first time an ultrasensitive electrochemical chiral biosensor for cysteine (Cys) based on magnetic nanoparticles (Fe3O4@PDA/Cu xO) as electrode units. d-Cys-Cu2+-d-Cys formed in the presence of cysteine exhibits strong stability and a shielding effect on the redox current of indicator Cu2+, which can be used to quantify and recognize d-Cys by square wave voltammetry. Simultaneous detection of d-Cys and homocysteine (Hcy) is achieved in the presence of other amino acids, demonstrating an excellent selectivity of the sensor. Moreover, aided by the enrichment treatment effect of magnetic micronanoelectrodes, an ultrahigh sensitivity up to 102 MUA MUM-1 cm-2 was achieved, the detection limit is reduced to picomolar level (83 pM) for d-Cys and can be used for the recognition of cysteine enantiomers. The proposed method has been verified by real sample analysis with satisfactory results. The results highlight the feasibility of our proposed strategy for magnetic micronanoelectrode sensor, electrochemical recognition, and quantification of d-Cys, which can be more broadly applicable than that with traditional electrode structures and further advance the field of electrochemical sensors. PMID- 29461044 TI - Antibiotic Susceptibility Determination within One Cell Cycle at Single-Bacterium Level by Stimulated Raman Metabolic Imaging. AB - The widespread use of antibiotics has significantly increased the number of resistant bacteria, which has also increased the urgency of rapid bacterial detection and profiling their antibiotic response. Current clinical methods for antibiotic susceptibility testing (AST) rely on culture and require at least 16 to 24 h to conduct. Therefore, there is an urgent need for a rapid method that can test the susceptibility of bacteria in a culture-free manner. Here we demonstrate a rapid AST method by monitoring the glucose metabolic activity of live bacteria at the single-cell level with hyperspectral stimulated Raman scattering (SRS) imaging. Using vancomycin-susceptible and -resistant enterococci E. faecalis as models, we demonstrate that the metabolic uptake of deuterated glucose in a single living bacterium can be quantitatively monitored via hyperspectral SRS imaging. Remarkably, the metabolic activity of susceptible bacteria responds differently to antibiotics from the resistant strain within only 0.5 h from the addition of antibiotics. Therefore, bacterial susceptibility and the minimum inhibitory concentration (MIC) of antibiotics can be determined within one cell cycle. Our metabolic imaging method is applicable to other bacteria species including E. coli, K. Pneumoniae, and S. aureus as well as different antibiotics, regardless of their mechanisms of inhibiting or killing bacteria. PMID- 29461043 TI - Li4SiO4-Based Artificial Passivation Thin Film for Improving Interfacial Stability of Li Metal Anodes. AB - An amorphous SiO2 (a-SiO2) thin film was developed as an artificial passivation layer to stabilize Li metal anodes during electrochemical reactions. The thin film was prepared using an electron cyclotron resonance-chemical vapor deposition apparatus. The obtained passivation layer has a hierarchical structure, which is composed of lithium silicide, lithiated silicon oxide, and a-SiO2. The thickness of the a-SiO2 passivation layer could be varied by changing the processing time, whereas that of the lithium silicide and lithiated silicon oxide layers was almost constant. During cycling, the surface of the a-SiO2 passivation layer is converted into lithium silicate (Li4SiO4), and the portion of Li4SiO4 depends on the thickness of a-SiO2. A minimum overpotential of 21.7 mV was observed at the Li metal electrode at a current density of 3 mA cm-2 with flat voltage profiles, when an a-SiO2 passivation layer of 92.5 nm was used. The Li metal with this optimized thin passivation layer also showed the lowest charge-transfer resistance (3.948 Omega cm) and the highest Li ion diffusivity (7.06 * 10-14 cm2 s-1) after cycling in a Li-S battery. The existence of the Li4SiO4 artificial passivation layer prevents the corrosion of Li metal by suppressing Li dendritic growth and improving the ionic conductivity, which contribute to the low charge transfer resistance and high Li ion diffusivity of the electrode. PMID- 29461045 TI - Electrochemical Sensing of Bisphenol A on Facet-Tailored TiO2 Single Crystals Engineered by Inorganic-Framework Molecular Imprinting Sites. AB - Noble metals, nanostructured carbon, and their hybrids are widely used for electrochemical detection of persistent organic pollutants. However, despite of the rapid detection process and high accuracy, these materials generally suffer from high costs, metallic impurity, heterogeneity, irreversible adsorption and poor sensitivity. Herein, the high-energy {001}-exposed TiO2 single crystals with specific inorganic-framework molecular recognition ability was prepared as the electrode material to detect bisphenol A (BPA), a typical and widely present organic pollutant in the environment. The oxidation peak current was linearly correlated to the BPA concentration from 10.0 nM to 20.0 MUM ( R2 = 0.9987), with a low detection limit of 3.0 nM (S/N = 3). Furthermore, it exhibited excellent discriminating ability, high anti-interference capacity, and good long-term stability. Its good performance for BPA detection in real environmental samples, including tap water, lake and river waters, domestic wastewater, and municipal sludge, was also demonstrated. This work extends the applications of TiO2 semiconductor and suggests that this material could be used as a highly active, stable, low-cost, and environmentally benign electrode material for electrochemical sensing. PMID- 29461046 TI - Three-Dimensional-Bioprinted Dopamine-Based Matrix for Promoting Neural Regeneration. AB - Central nerve repair and regeneration remain challenging problems worldwide, largely because of the extremely weak inherent regenerative capacity and accompanying fibrosis of native nerves. Inadequate solutions to the unmet needs for clinical therapeutics encourage the development of novel strategies to promote nerve regeneration. Recently, 3D bioprinting techniques, as one of a set of valuable tissue engineering technologies, have shown great promise toward fabricating complex and customizable artificial tissue scaffolds. Gelatin methacrylate (GelMA) possesses excellent biocompatible and biodegradable properties because it contains many arginine-glycine-aspartic acids (RGD) and matrix metalloproteinase sequences. Dopamine (DA), as an essential neurotransmitter, has proven effective in regulating neuronal development and enhancing neurite outgrowth. In this study, GelMA-DA neural scaffolds with hierarchical structures were 3D-fabricated using our custom-designed stereolithography-based printer. DA was functionalized on GelMA to synthesize a biocompatible printable ink (GelMA-DA) for improving neural differentiation. Additionally, neural stem cells (NSCs) were employed as the primary cell source for these scaffolds because of their ability to terminally differentiate into a variety of cell types including neurons, astrocytes, and oligodendrocytes. The resultant GelMA-DA scaffolds exhibited a highly porous and interconnected 3D environment, which is favorable for supporting NSC growth. Confocal microscopy analysis of neural differentiation demonstrated that a distinct neural network was formed on the GelMA-DA scaffolds. In particular, the most significant improvements were the enhanced neuron gene expression of TUJ1 and MAP2. Overall, our results demonstrated that 3D-printed customizable GelMA-DA scaffolds have a positive role in promoting neural differentiation, which is promising for advancing nerve repair and regeneration in the future.

AB - Ag2[W6I14] and A2- x[W6I14] compounds with A = Na, Li were prepared from binary tungsten iodides (W3I12) and corresponding metal iodides. Their crystal structures are analyzed on the basis of X-ray diffraction data. 7Li and 23Na solid-state NMR measurements reveal that Li+ and Na+ ions are distributed over two sites in the respective structures. These results shed some new light on A x[M6I14] with A = alkali and M = Mo, W compounds being reported with x = 1 and 2, which exhibit photophysical properties. The lithium compound is an exception in the series of A2- x[W6I14] compounds, because it is the only compound which is soluble in water. PMID- 29461048 TI - Selective Recognition of Hg2+ ion in Water by a Functionalized Metal-Organic Framework (MOF) Based Chemodosimeter. AB - A metal-organic framework (MOF)-based highly selective and sensitive probe (UiO 66@Butyne) for the detection of Hg(II) ion has been developed. To the best our knowledge, this is the foremost example of a chemodosimeter-based approach to sense Hg(II) ion using a MOF-based probe. The chemical stability of UiO-66@Butyne renders the sensitive detection of Hg2+ ion in an aqueous phase. UiO-66@Butyne has been found to be selective for Hg(II) ions even in the presence of other metal ions. PMID- 29461049 TI - Emerging Biodegradation of the Previously Persistent Artificial Sweetener Acesulfame in Biological Wastewater Treatment. AB - The persistence of acesulfame (ACE) in wastewater treatment (and subsequently the aquatic environment) has led to its use as a marker substance for wastewater input into surface water and groundwater. However, ACE degradation of >85% during summer and autumn was observed in nine German wastewater treatment plants (WWTPs). Annual removal performance was more stable in larger plants, enhanced by low biological oxygen demand and impeded by water temperatures below 10 degrees C. Literature data suggest that the potential to degrade ACE emerged in WWTPs around the year 2010. This development is ongoing, as illustrated by ACE content in the German rivers Elbe and Mulde: Between 2013 and 2016 the ACE mass load decreased by 70-80%. In enrichment cultures with ACE as sole carbon source the carbonaceous fraction of ACE was removed completely, indicating catabolic biotransformation and the inorganic compound sulfamic acid formed in quantitative amounts. Sequencing of bacterial 16S rRNA genes suggests that several species are involved in ACE degradation, with proteobacterial species affiliated to Phyllobacteriaceae, Methylophilaceae, Bradyrhizobiaceae, and Pseudomonas becoming specifically enriched. ACE appears to be the first micropollutant for which the evolution of a catabolic pathway in WWTPs has been witnessed. It can yet only be speculated whether the emergence of ACE removal in WWTPs in different regions of the world is due to independent evolution or to global spreading of genes or adapted microorganisms. PMID- 29461050 TI - Modular Access to Azepines by Directed Carbonylative C-C Bond Activation of Aminocyclopropanes. AB - A modular Rh-catalyzed entry to azepines is outlined. Under a CO atmosphere, protecting group directed C-C bond activation of aminocyclopropanes provides rhodacyclopentanones. These intermediates are effective for intramolecular C-H metalation of either an N-aryl or N-vinyl unit en route to azepine ring systems. Thus, byproduct-free heterocyclizations are enabled by sequential C-C activation and C-H functionalization steps. PMID- 29461051 TI - Mechanistic Investigations of Photoinduced Oxygenation of Ru(II) Bis-bipyridyl Flavonolate Complexes. AB - We previously reported that a Ru-bound flavonolate model of flavonol dioxygenases, [RuII(bpy)2(3-hydroxyfla)][PF6], photochemically reacts with dioxygen in two different manners. Broad-band excitation generates mixtures of products characteristic of 1,3-addition of dioxygen across the central pyrone ring, as is observed in enzymatic reactions. However, low temperature excitation at wavelengths longer than 400 nm generates a unique Ru-bound 2 benzoatophenylglyoxylate product resulting from a 1,2-dioxetane intermediate. Herein, we investigate this reactivity in a series of Ru(II)bis-bipyridyl flavonolate complexes [RuII(bpy)2(3-hydroxyflaR)][PF6] (bpy = 2,2'-bipyridine; fla = flavonolate; R = p-OMe (1), p-Me (2), p-H (3), p-Cl (4)), and [RuII(bpy)2(5 hydroxyfla)][PF6] (5). The complexes' structures, photophysical and electrochemical properties, and photochemical reactivity with oxygen were investigated in detail. Two different reaction product mixtures, from 1,2- and 1,3-additions of dioxygen, are observed by illumination into distinct excitation/emission manifolds. By analogy to previous reports of excited state intramolecular proton transfer, the two manifolds are attributed to tautomeric diradicals that predict the observed reactivity patterns. PMID- 29461052 TI - Insights into B-Site Ordering in Double Perovskite-Type Ba3Ca1+ xNb2- xO9-delta (0 <= x <= 0.45): Combined Synchrotron and Neutron Diffraction and Electrical Transport Analyses. AB - Perovskite-type metal oxides are being used in a wide range of technologies, including fuel cells, batteries, electrolyzers, dielectric capacitors, and sensors. One of their remarkable structural properties is cationic ordering in A or B sites, which affects electrical transport properties under different gaseous atmospheres, and chemical stability under CO2 and humid conditions. For example, a simple-perovskite-type Y-doped BaCeO3 forms BaCO3 and ((Ce,Y)O2-delta) under CO2 at elevated temperature, while B-site-ordered double-perovskite-type Ba3Ca1.18Nb1.82O9-delta remains chemically stable under the same conditions. Early structural studies on Ba3Ca1+ xNb2- xO9-delta (BCN) showed that the B-site ordering (1:1) is sensitive to the Ca content. However, ambiguity rises, as 1:2 B site ordering was not observed in the parent and doped analogues when x was varied, which motivated us to revisit the complex oxides BCN ( x = 0-0.45) to determine the atomic structure by a mean of combined synchrotron X-ray and neutron diffraction methods. Surprisingly, the B-site ordering increases with increasing Ca/Nb mixing in the B-sites in BCN. In addition, the electrical conductivity of BCN was found to be the highest at x = ~0.18, and it decreased as the Ca/Nb ratio further increased in BCN. Such a result was very similar to that for the Y-doped BaZrO3, where the mobility of proton carriers was found to decrease as the dopant (Y) increased. A higher Ca/Nb ratio also promotes the growth of grain size, as Ca ions could serve as a sintering aid, improving the structural integrity. PMID- 29461053 TI - Research Progress of Polycyclic Polyprenylated Acylphloroglucinols. AB - Polycyclic polyprenylated acylphloroglucinols (PPAPs) are a class of hybrid natural products sharing the mevalonate/methylerythritol phosphate and polyketide biosynthetic pathways and showing considerable structure and bioactivity diversity. This review discusses the progress of research into the chemistry and biological activity of 421 natural PPAPs in the past 11 years as well as in-depth studies of biological activities and total synthesis of some PPAPs isolated before 2006. We created an online database of all PPAPs known to date at http://www.chem.uky.edu/research/grossman/PPAPs . Two subclasses of biosynthetically related metabolites, spirocyclic PPAPs with octahydrospiro[cyclohexan-1,5'-indene]-2,4,6-trione core and complicated PPAPs produced by intramolecular [4 + 2] cycloadditions of MPAPs, are brought into the PPAP family. Some PPAPs' relative or absolute configurations are reassigned or critically discussed, and the confusing trivial names in PPAPs investigations are clarified. Pharmacologic studies have revealed a new molecular mechanism whereby hyperforin and its derivatives regulate neurotransmitter levels by activating TRPC6 as well as the antitumor mechanism of garcinol and its analogues. The antineoplastic potential of some type B PPAPs such as oblongifolin C and guttiferone K has increased significantly. As a result of the recent appearances of innovative synthetic methods and strategies, the total syntheses of 22 natural PPAPs including hyperforin, garcinol, and plukenetione A have been accomplished.

PMID- 29461055 TI - Bidirectional Degradation of DNA Cleavage Products Catalyzed by CRISPR/Cas9. AB - Since the initial characterization of Streptococcus pyogenes CRISPR/Cas9 as a powerful gene-editing tool, it has been widely accepted that Cas9 generates blunt ended DNA products by concerted cleavage of the target (tDNA) and non-target (ntDNA) strands three nucleotides away from the protospacer adjacent motif (PAM) by HNH and RuvC nuclease active sites, respectively. Following initial DNA cleavage, RuvC catalyzes 3'->5' degradation of the ntDNA resulting in DNA products of various lengths. Here, we found that Cas9 selects multiple sites for initial ntDNA cleavage and preferentially generates staggered-ended DNA products containing single-nucleotide 5'-overhangs. We also quantitatively evaluated 3' >5' post-cleavage trimming (PCT) activity of RuvC to find that ntDNA degradation continues up to the -10 position on the PAM distal DNA product and is kinetically significant when compared to extremely slow DNA product release. We also discovered a previously unidentified 5'->3' PCT activity of RuvC which can shorten the PAM proximal ntDNA product by precisely one nucleotide with a comparable rate as the 3'->5' PCT activity. Taken together, our results demonstrate that RuvC-catalyzed PCT ultimately generates DNA fragments with heterogeneous ends following initial DNA cleavage including a PAM proximal fragment with a blunt end and a PAM distal fragment with a staggered-end, 3' recessed on the ntDNA strand. These kinetic and biochemical findings underline the importance of temporal control of Cas9 during gene-editing experiments and help explain the patterns of nucleotide insertions at sites of Cas9-catalyzed gene modification in vivo.

AB - Total synthesis of (+/-)-adunctin B, a natural product isolated from Piper aduncum (Piperaceae), has been achieved using two different strategies, in seven and three steps. The efficient approach features highly atom economical and diastereoselective Friedel-Crafts acylation, alkylation reaction and palladium catalyzed Wacker type oxidative cyclization. PMID- 29461057 TI - Elaboration of Cellulose Nanocrystal/Ge-Imogolite Nanotube Multilayered Thin Films. AB - Multilayered thin films combining two oppositely charged nanoparticles (NPs), i.e., cellulose nanocrystals (CNCs) and Ge-imogolites, have been successfully obtained by the layer-by-layer method. CNC/Ge-imogolite (NP/NP) film growth patterns were studied by comparing growth mode of all of the nanoparticles thin films to that of films composed of CNC or Ge-imogolites combined with polyelectrolytes (PEs), i.e., cationic poly(allylamine hydrochloride) and anionic poly-4-styrene sulfonate (NP/PE films). NP/NP and NP/PE films growth patterns were found to be different. To get a deeper understanding of the growth mode of NP/NP, impact of different parameters, such as imogolites aspect ratio, adsorption time, ionic strength, and repeated immersion/drying, was evaluated and influence of the drying step is emphasized. The aspect ratio of imogolites was identified as an important feature for the film's architecture. The short Ge imogolites form denser films because the surface packing was more efficient. PMID- 29461058 TI - Intramolecular Photocycloaddition of 2(5 H)-Furanones to Temporarily Tethered Terminal Alkenes as a Stereoselective Source of Enantiomerically Pure Polyfunctionalyzed Cyclobutanes. AB - Allyloxymethyloxymethyl and 4-pentenoyloxymethyl substituents have been used as tethering groups to study the intramolecular [2 + 2] photocycloaddition of chiral 5-substituted 2(5 H)-furanones. The photoreactions proceed in good yield and provide the expected regio- and diastereoselective tricyclic compounds with complementary regioselectivity, which depends on whether the vinyl chain is attached to the furanone by an acetal or an ester linkage. Computational simulations agree with experimental observations and indicate that the origin of the different observed regioselectivity in the intramolecular photochemical reaction of lactones 5 and 6 arises from the relative stability of the initial conformers. The synthetic potential of the enantiomerically pure photoadducts is illustrated by preparing an all- cis 1,2,3-trisubstituted cyclobutane bearing fully orthogonally protected hydroxyl groups. PMID- 29461059 TI - Role of Dimers in the cAMP-Dependent Activation of Hyperpolarization-Activated Cyclic-Nucleotide-Modulated (HCN) Ion Channels. AB - Hyperpolarization-activated cyclic-nucleotide-modulated (HCN) ion channels control rhythmicity in neurons and cardiomyocytes. Cyclic AMP (cAMP) modulates HCN activity through the cAMP-induced formation of a tetrameric gating ring spanning the intracellular region (IR) of HCN. Although evidence from confocal patch-clamp fluorometry indicates that the cAMP-dependent gating of HCN occurs through a dimer of dimers, the structural and dynamical basis of cAMP allostery in HCN dimers has so far remained elusive. Thus, here we examine how dimers influence IR structural dynamics, and the role that such structural dynamics play in HCN allostery. To this end, we performed molecular dynamics (MD) simulations of HCN4 IR dimers in their fully apo, fully holo, and partially cAMP-bound states, resulting in a total simulated time of 1.2 MUs. Comparative analyses of these MD trajectories, as well as previous monomer and tetramer simulations utilized as benchmarks for comparison, reveal that dimers markedly sensitize the HCN IR to cAMP-modulated allostery. Our results indicate that dimerization fine tunes the IR dynamics to enhance, relative to both monomers and tetramers, the allosteric intra- and interprotomer coupling between the cAMP-binding domain and tetramerization domain components of the IR. The resulting allosteric model provides a viable rationalization of electrophysiological data on the role of IR dimers in HCN activation. PMID- 29461060 TI - Anomalous Solubility of an Inert Solid in a Binary Liquid Mixture with a Critical Point of Solution. AB - We consider the dissolution of a chemically inert solid in a binary liquid mixture with a critical point of solution. When the mixture, acting as the solvent, has come to equilibrium with the solid, the state of the system is completely described by the temperature, pressure, and a concentration variable formed by dividing the molar amount of one solvent component by that of the other. Under conditions of fixed pressure, the principle of critical point isomorphism predicts that the slope of a van't Hoff plot of the solubility of the solid should diverge toward infinity as the temperature enters the critical region. The sign of the divergence is negative when the dissolution is endothermic, whereas it is positive when the dissolution is exothermic. In experiments where excess solid phenolphthalein dissolves in a binary mixture of nitrobenzene + dodecane, we have observed exothermic dissolution concurrently with a positive divergence of the van't Hoff slope. The data are insufficiently precise to compute an accurate numerical value for the exponent of the temperature power law expected to govern this divergence; nevertheless, on the basis of Widom scaling theory, we argue that the exponent should be equal to 0.326, which is identical to the value of the exponent that governs the temperature dependence of the shape of the liquid-liquid coexistence curve. Being entirely physical in nature, the anomalous solubility effect should be observable in the case of any chemically inert solid dissolving in any one of the more than 1000 liquid pairs known to have a critical point of solution. PMID- 29461061 TI - Electrical Stressing Induced Monolayer Vacancy Island Growth on TiSe2. AB - To ensure practical applications of atomically thin transition metal dichalcogenides, it is essential to characterize their structural stability under external stimuli such as electric fields and currents. Using vacancy monolayer islands on TiSe2 surfaces as a model system, we have observed nonlinear area evolution and growth from triangular to hexagonal driven by scanning tunneling microscopy (STM) subjected electrical stressing. The observed growth dynamics represent a 2D departure from the linear area growth law expected for bulk vacancy clustering. Our simulations of monolayer island evolution using phase field modeling and first-principles calculations are in good agreement with our experimental observations, and point toward preferential edge atom dissociation under STM scanning driving the observed nonlinear area growth. We further quantified a parabolic growth rate dependence with respect to the tunneling current magnitude. The results could be potentially important for device reliability in systems containing ultrathin transition metal dichalcogenides and related 2D materials subject to electrical stressing. PMID- 29461062 TI - Understanding the MXene Pseudocapacitance. AB - MXenes have attracted great attention as next-generation capacitive energy storage materials, but the mechanisms underlying their pseudocapacitive behavior are not well understood. Here we provide a theoretical description of the surface redox process of Ti3C2T x (T = O, OH), a prototypical MXene, in 1 M H2SO4 electrolyte, based on joint density functional theory with an implicit solvation model and the analysis of Gibbs free energy under a constant-electrode potential. From the dependence of the O/OH ratio (or the surface H coverage) and the surface charge on the applied potential, we obtain a clear picture of the capacitive energy-storage mechanism of Ti3C2T x that shows good agreement with previous experimental findings in terms of the integral capacitance and Ti valence change. We find a voltage-dependent redox/double-layer co-charging behavior: the capacitive mechanism is dominated by the redox process, but the electric double layer charge works against the redox process. This new insight may be useful in improving the capacitance of MXenes. PMID- 29461063 TI - Nickel-Catalyzed Reductive Bis-Allylation of Alkynes.

AB - Enantioselective synthesis of alpha-aryl and alpha-heteroaryl piperidines is reported. The key step is an iridium-catalyzed asymmetric hydrogenation of substituted N-benzylpyridinium salts. High levels of enantioselectivity up to 99.3:0.7 er were obtained for a range of alpha-heteroaryl piperidines. DFT calculations support an outersphere dissociative mechanism for the pyridinium reduction. Notably, initial protonation of the final enamine intermediate determines the stereochemical outcome of the transformation rather than hydride reduction of the resultant iminium intermediate.

AB - The use of selenocysteines and various cross-linkers to induce helicity in a bioactive peptide is described. The higher reactivity of selenocysteine, relative to cysteine, facilitates rapid cross-linking within unprotected linear peptides under mild aqueous conditions. Alkylating agents of variable topology and electrophilicity were used to link pairs of selenocysteines within a p53 peptide. Facile selenoether formation enables diverse tailoring of the helical peptide structure. PMID- 29461068 TI - Social learning and associative processes: A synthesis. AB - Social learning is often considered different from asocial learning in both its characteristics and mechanisms. I presented pigeons with a concurrent discrimination task in which they received artificial social information, consisting of simple shapes that distributed themselves between two options similarly to how conspecifics might. Subjects in some conditions combined personal information about the two options with this social-like information, but subjects in conditions in which personal information was very reliable ignored the social cues, much like cases in which animals only choose to copy choices of others under certain conditions. I present a modification of a popular associative model of individual learning that can replicate these results, despite not distinguishing between social and asocial cues. The model suggests that the adaptive use of social information does not require the assumption of specifically social learning strategies, but may be driven by the overshadowing of less reliable asocial cues by more reliable social cues. (PsycINFO Database Record PMID- 29461067 TI - Perceptual boundaries cause mnemonic trade-offs between local boundary processing and across-trial associative binding. AB - Episodic memories are not veridical records of our lives, but rather are better described as organized summaries of experience. Theories and empirical research suggest that shifts in perceptual, temporal, and semantic information lead to a chunking of our continuous experiences into segments, or "events." However, the consequences of these contextual shifts on memory formation and organization remains unclear. In a series of 3 behavioral studies, we introduced context shifts (or "event boundaries") between trains of stimuli and then examined the influence of the boundaries on several measures of associative memory. In Experiment 1, we found that perceptual event boundaries strengthened associative binding of item-context pairings present at event boundaries. In Experiment 2, we observed reduced temporal order memory for items encoded in distinct events relative to items encoded within the same event, and a trade-off between the speed of processing at boundaries, and temporal order memory for items that flanked those boundaries. Finally, in Experiment 3 we found that event organization imprinted structure on the order in which items were freely recalled. These results provide insight into how boundary- and event-related organizational processes during encoding shape subsequent representations of events in episodic memory.

AB - Determination of a direction of travel is a necessary component of successful navigation, and various species appear to use the geometric shape (global geometric cues) of an environment to determine direction. Yet, debate remains concerning which objective shape parameter is responsible for spatial reorientation via global geometric cues. For example, the principal axis of space, which runs through the centroid and approximate length of the space, and the medial axis of space, a trunk and branch system that fills the shape, have each been suggested as a basis to explain global spatial reorientation. As the principal- and medial-axis accounts appear to have substantial theoretical implications regarding the nature of shape perception, spatial memory, and the underlying psychological representations of space, it appears critical to empirically differentiate between these global geometric accounts. The present experiment explicitly placed predictions from the principal- and medial-axis based accounts of global spatial reorientation in conflict for theoretical diagnostic purposes. We used a standard reorientation paradigm in which human participants first reoriented in a rectangular environment; subsequent testing in a critical I-shaped enclosure allowed dissociation of the principal- or medial axis-based accounts. We show that reorientation in the I-shaped enclosure was consistent with the principal-axis account and inconsistent with the medial-axis account. We suggest that the use of the principal axis for spatial reorientation is a relatively simple and efficient way to establish directionality that would be advantageous over a more complex and less efficient medial-axis-based account. (PsycINFO Database Record PMID- 29461070 TI - A randomized trial of contingency management for smoking cessation in the homeless. AB - Smoking-cessation services are an unmet need among the homeless, who smoke at rates more than 4 times the national estimate. Successful interventions have high potential for improving tobacco-related health disparities among homeless smokers. Contingency management (CM) is a behavioral intervention with efficacy in a number of substance-use disorder populations, including smokers. However, no randomized studies have evaluated the effect of CM in homeless smokers. We examined smoking-related outcomes in homeless smokers (N = 70) randomized to standard-care (SC) smoking cessation involving transdermal nicotine-replacement therapy (NRT), standard counseling, and carbon monoxide (CO) monitoring or the same SC plus CM for negative CO sample submissions. Participants randomized to CM achieved significantly longer durations of consecutive abstinence and submitted a significantly higher proportion of CO-negative samples relative to standard-care participants. At 4 weeks postquit day, 22% were abstinent in the CM condition and 9% were abstinent in the SC condition. At the 6-month follow-up, about 10% of smokers in both conditions were abstinent. This study demonstrates that CM is an efficacious option to increase initial quit rates in homeless smokers, but methods to extend effects are needed. (PsycINFO Database Record PMID- 29461072 TI - Nurturing the hope of youth in care: The contribution of mentoring. AB - Hope has long been viewed as important to individuals attempting to overcome obstacles. Overall hope is the combination of one's appraisal of capability and determination to achieve goals (Agency) and identifying viable routes to reach them (Pathway) (Snyder, 1994). The main goal of this study was to examine the incremental contribution of mentoring to hope among youth on the verge of leaving care above and beyond related personal characteristics and placement history. The sample included 148 adolescents in residential care in Israel who had adult mentors (ages 16-19). Results showed that lower levels of parental education and being in a welfare residential placement were associated with decreased levels of hope. Mentoring length and various mentoring functions ("role model," "parental figure," and "independence promoter") were found to have a significant contribution to the prediction of hope above and beyond associated individual and placement variables. Based upon these findings, residential care leaders should recruit and select mentors for longevity, and train mentors to serve as role models and parental figures who focus on independent living in order to influence hope among youth who are about to leave care. (PsycINFO Database Record PMID- 29461071 TI - Borderline personality disorder affective instability: What you know impacts how you feel. AB - The current study examined the role of conceptual knowledge and language in affective instability (AI) associated with borderline personality disorder (BPD). Forty-six females meeting criteria for BPD and 51 nonclinical female control participants without BPD completed a measure of general vocabulary and a semantic similarities task that provided estimates of the degree to which participants weighted information about valence and arousal in their understanding of emotion language. Feelings of valence and arousal were assessed using the Self-Assessment Manikin in response to 62 emotionally evocative images, which was used to derive estimates of AI. BPD status was associated with valence and arousal AI at a bivariate level, but not after controlling for language variables (general vocabulary and semantic valence and arousal foci). Participants with stronger as opposed to weaker vocabularies exhibited less AI, and participants who emphasized arousal more in their conceptual representations of emotions exhibited less AI than those who emphasized it to a lesser degree. With the inclusion of language variables in a regression equation with BPD status predicting AI, semantic arousal focus, but not general vocabulary, was a significant predictor of AI. Consistent with psychological constructionist models of emotion that specify an active role of language throughout the emotion generation process, these findings suggest that language capacity (general vocabulary and the degree to which arousal influences understanding of emotion words) is an important determinant of the AI associated with BPD. (PsycINFO Database Record PMID- 29461073 TI - Rethinking the acculturation gap-distress theory among asian americans: Testing bidirectional indirect relations. AB - The acculturation gap-distress theory postulates that parent-offspring acculturation mismatch precipitates greater intergenerational conflict in immigrant families, which in turn increases the risk for psychological problems among offspring. Whereas cross-sectional studies have shown support for these theory-informed relations, comparatively little is known about whether acculturation mismatch negatively affects psychological functioning, or whether offspring's psychological problems precipitate greater perceived acculturation mismatch via intergenerational cultural conflict. Furthermore, more research is needed to investigate how acculturation and family conflict affect Asian Americans transitioning into college and emerging adulthood. Across two measurement occasions, two cohorts of Asian American first-year college students (N = 555, Mage = 17.99, 56.0% women) completed survey questionnaires assessing their perception of parent-offspring acculturation discrepancies, acculturation related intergenerational conflict, and internalizing and externalizing symptoms. For both sets of psychological functioning, gender invariant structural equation models testing the bidirectional relations demonstrated adequate fit for the data. In the case of externalizing symptoms, acculturation mismatch marginally significantly predicted subsequent intergenerational conflict, but acculturation mismatch did not predict externalizing symptoms via intergenerational cultural conflict. By contrast, offspring's internalizing and externalizing symptoms respectively predicted greater self-reported intergenerational cultural conflict, which in turn predicted perceived parent-offspring acculturation mismatch over time. These indirect relations suggested that both internalizing and externalizing symptoms indirectly contributed to greater acculturation mismatch through the presence of intergenerational cultural conflict, but data did not support the acculturation gap-distress theory. Theoretical and clinical implications as they pertain to Asian American emerging adults are discussed. (PsycINFO Database Record PMID- 29461074 TI - Top-down contributions to attention shifting and disengagement: A template model of visual attention. AB - Two separate systems are involved in the control of spatial attention; one that is driven by a goal, and the other that is driven by stimuli. While the goal- and stimulus-driven systems follow different general principles, they also interplay with each other. However, the mechanism by which the goal-driven system influences the stimulus-driven system is still debated. The present study examined top-down contributions to two components of attention orienting, shifting and disengagement, with an experimental paradigm in which participants held a visual item in short-term memory (STM) and performed a prosaccade task with a manipulation of the gap between fixation offset and target onset. Four experiments showed that the STM content accelerated shifting and impaired disengagement, but the influence on disengagement depended on the utility of STM in guiding attention toward the target. Thus, the use of STM was strategic. Computational models of visual attention were fitted to the experimental data, which suggested that the top-down contributions to shifting was more prominent than those to disengagement. The results indicate that the current modeling framework was particularly useful when examining the contributions of theoretical constructs for the control of visual attention, but it also suggests limitations.

(PsycINFO Database Record PMID- 29461076 TI - The single lineup paradigm: A new way to manipulate target presence in eyewitness identification experiments. AB - The suspect in eyewitness lineups may be guilty or innocent. These possibilities are traditionally simulated in eyewitness identification studies using a dual lineup paradigm: All witnesses observe the same perpetrator and then receive one of two lineups. In this paradigm, the suspect's guilt is manipulated by including the perpetrator in one lineup and an innocent suspect in the other. The lineup is then filled with people matched to either the suspect (resulting in different fillers in perpetrator-present and perpetrator-absent lineups) or to the perpetrator (resulting in the same fillers in each lineup). An inescapable feature of the dual-lineup paradigm is that the perpetrator-present and perpetrator-absent lineups differ not only in the suspect's guilt, but also in their composition. Here, we describe a single-lineup paradigm: Subjects observe one of two perpetrators and then all subjects receive the same lineup containing one of the perpetrators. This alternative paradigm allows manipulation of the suspect's guilt without changing the lineup's composition. In three experiments, we applied the single-lineup paradigm to explore suspect-filler similarity and consistently found that increasing similarity reduced perpetrator identifications but did little to prevent innocent suspect misidentifications. Conversely, when fillers were matched to the perpetrator using a dual-lineup paradigm, increasing similarity reduced identification of perpetrators and innocent suspects. This finding suggests that the effect of filler similarity may depend on the person to whom the fillers are matched. We suggest that the single-lineup paradigm is a more ecologically valid and better controlled approach to creating suspect matched lineups in laboratory investigations of eyewitness memory than existing procedures. (PsycINFO Database Record PMID- 29461077 TI - Who deserves basic rights? People condone violations of procedural and physical rights in the treatment of terrorist suspects. AB - Public discourse regarding the treatment of terrorist suspects typically emphasizes utilitarian "greater-good" justifications related to ensuring public safety. By contrast, we hypothesized that laypeople's judgments of how suspected terrorists ought to be treated are more strongly informed by retributive concerns related to deservingness. Participants (N = 607, Mage = 34.25, recruited via Mechanical Turk) read about a terrorist suspect who was (vs. was not) presented as deserving of punishment and described as posing (vs. not posing) a continued threat to public safety. Participants rated the acceptability of procedural and physical rights violations occurring during the arrest and interrogation of the suspect and provided their perceptions of the suspect's dangerousness and deservingness of lawful treatment. We found that participants were more willing to condone rights violations when the suspect was (vs. was not) deserving of punishment. This willingness was not affected by the continued threat manipulation. Moreover, the effect of the punishment deservingness manipulation was mediated by perceptions that suspected terrorists are less deserving of having their rights upheld, but not by perceived dangerousness. Retributive concerns related to deservingness can thus lead people to condone the denial of suspected terrorists' basic rights, which may have consequences for the curtailment of all citizens' civil liberties. (PsycINFO Database Record PMID- 29461078 TI - Police managers' self-control and support for organizational justice. AB - Recent policing research has identified a positive relationship between line level officers' perceptions of organizational justice and their adherence to agency goals and job satisfaction. However, we have little understanding of the factors that are related to police managers' support for organizational justice when interacting with employees. We collected survey data from a sample of U.S. command-level officers (N = 211) who attended a training program in a southern state to address this gap in the literature. The anonymous survey was administered in-person to participating command-level police officers prior to their training program. Our multivariate regression analysis revealed that police managers who reported higher levels of self-control were more supportive of organizational justice (b = .26, p < .01). Additionally, police managers who reported higher quality relationships with their colleagues expressed greater support for organizational justice (b = .02, p = .02). Respondents' self legitimacy was not significantly associated with their support for organizational justice. This study contributes to the organizational justice literature by presenting the first analysis that links police commanders' self-control to support for organizational justice within their management practices. The findings help pinpoint the types of individuals who may be best equipped to be fair police managers. (PsycINFO Database Record PMID- 29461079 TI - Neural activity in the reward-related brain regions predicts implicit self esteem: A novel validity test of psychological measures using neuroimaging. AB - Self-esteem, arguably the most important attitudes an individual possesses, has been a premier research topic in psychology for more than a century. Following a surge of interest in implicit attitude measures in the 90s, researchers have tried to assess self-esteem implicitly to circumvent the influence of biases inherent in explicit measures. However, the validity of implicit self-esteem measures remains elusive. Critical tests are often inconclusive, as the validity of such measures is examined in the backdrop of imperfect behavioral measures. To overcome this serious limitation, we tested the neural validity of the most widely used implicit self-esteem measure, the implicit association test (IAT). Given the conceptualization of self-esteem as attitude toward the self, and neuroscience findings that the reward-related brain regions represent an individual's attitude or preference for an object when viewing its image, individual differences in implicit self-esteem should be associated with neural signals in the reward-related regions during passive-viewing of self-face (the most obvious representation of the self). Using multi-voxel pattern analysis (MVPA) on functional MRI (fMRI) data, we demonstrate that the neural signals in the reward-related regions were robustly associated with implicit (but not explicit) self-esteem, thus providing unique evidence for the neural validity of the self-esteem IAT. In addition, both implicit and explicit self-esteem were related, although differently, to neural signals in regions involved in self processing. Our finding highlights the utility of neuroscience methods in addressing fundamental psychological questions and providing unique insights into important psychological constructs. (PsycINFO Database Record PMID- 29461080 TI - Appraisal-driven facial actions as building blocks for emotion inference. AB - Although research on facial emotion recognition abounds, there has been little attention on the nature of the underlying mechanisms. In this article, using a "reverse engineering" approach, we suggest that emotion inference from facial expression mirrors the expression process. As a strong case can be made for an appraisal theory account of emotional expression, which holds that appraisal results directly determine the nature of facial muscle actions, we claim that observers first detect specific appraisals from different facial muscle actions and then use implicit inference rules to categorize and name specific emotions. We report three experiments in which, guided by theoretical predictions and past empirical evidence, we systematically manipulated specific facial action units individually and in different configurations via synthesized avatar expressions. Large, diverse groups of participants judged the resulting videos for the underlying appraisals and/or the ensuing emotions. The results confirm that participants can infer targeted appraisals and emotions from synthesized facial actions based on appraisal predictions. We also report evidence that the ability to correctly interpret the synthesized stimuli is highly correlated with emotion recognition ability as part of emotional competence. We conclude by highlighting the importance of adopting a theory-based experimental approach in future research, focusing on the dynamic unfolding of facial expressions of emotion. (PsycINFO Database Record PMID- 29461081 TI - The description of situations: Towards replicable domains of psychological situation characteristics. AB - Using the most comprehensive lexical approach with English adjectives to date, Parrigon et al. (2017) found 7 major dimensions of psychological situation characteristics (CAPTION: Complexity, Adversity, Positive Valence, Typicality, Importance, humOr, Negative Valence). Researchers using or studying situations may be interested in how well these dimensions empirically overlap with dimensions from other taxonomies, such as the DIAMONDS (Duty, Intellect, Adversity, Mating, pOsitivity, Negativity, Deception, Sociality). This comment highlights empirical and theoretical convergences between CAPTION and DIAMONDS scales, yielding evidence for 5 replicable dimensions. In general, average convergent correlations were substantial (.47-.69), much larger than discriminant ones (.18-.30), and as high as or higher than those typically found for Big Five scales. We highlight the opportunity to integrate different situation characteristics taxonomies and conclude with the plea for large-scale, cross cultural research that can further expand our knowledge on the structures of situation characteristics. (PsycINFO Database Record PMID- 29461082 TI - Why bottom-up taxonomies are unlikely to satisfy the quest for a definitive taxonomy of situations. AB - The recent advent of methods for large-scale data collection has provided an unprecedented opportunity for researchers who seek to develop a taxonomy of situations. Parrigon, Woo, Tay, and Wang's (2017) CAPTIONs model is the latest such effort. In this comment, I argue that although bottom-up approaches of this sort have clear value, they are unlikely to provide the sort of definitive, comprehensive, and theoretically integrative taxonomy that the field wants and needs. In large part, this is because bottom-up taxonomies represent what is common about situations and not what is theoretically important and influential about them. (PsycINFO Database Record PMID- 29461083 TI - Towards a comprehensive science of situations: On the importance of typicality and the lexical approach. AB - The two commentaries to the CAPTION derivation paper (Parrigon, Woo, Tay, & Wang, 2017) provided insightful points regarding the consistency of emergent dimensional structures in the extant literature (Rauthmann & Sherman, 2018, p. 482) and potential concerns regarding the use of the lexical approach to identify psychologically important situation dimensions (Reis, 2018, p. 489). In this rejoinder, we seek to further these important discussions by (a) emphasizing the importance of Typicality in understanding a broad range of psychological processes, (b) clarifying the utility of broad, dimensional-based situation taxonomies such as the CAPTION model for providing key theoretical and empirical linkages across discrete situations, as well as for capturing a broad range of psychologically meaningful dimensions of situations, and (c) reaffirming the need for cross-cultural/language and facet-level investigations of the CAPTION dimensions in future research. We hope that these discussions continue to advance the field toward a more comprehensive science of situations.

AB - Background and aims Recent research has suggested that social networking site use can be addictive. Although extensive research has been carried out on potential addiction to social networking sites, such as Facebook, Twitter, YouTube, and Tinder, only one very small study has previously examined potential addiction to Instagram. Consequently, the objectives of this study were to examine the relationships between personality, self-liking, daily Internet use, and Instagram addiction, as well as exploring the mediating role of self-liking between personality and Instagram addiction using path analysis. Methods A total of 752 university students completed a self-report survey, including the Instagram Addiction Scale (IAS), the Big Five Inventory (BFI), and the Self-Liking Scale. Results Results indicated that agreeableness, conscientiousness, and self-liking were negatively associated with Instagram addiction, whereas daily Internet use was positively associated with Instagram addiction. The results also showed that self-liking partially mediated the relationship of Instagram addiction with agreeableness and fully mediated the relationship between Instagram addiction with conscientiousness. Discussion and conclusions This study contributes to the small body of literature that has examined the relationship between personality and social networking site addiction and is one of only two studies to examine the addictive use of Instagram and the underlying factors related to it. PMID- 29461088 TI - Oral health and later coronary heart disease: Cohort study of one million people. AB - Aims Systematic reviews report an association between poorer oral health and an increased risk of coronary heart disease. This contentious relationship may not be causal but existing studies have been insufficiently well powered comprehensively to examine the role of confounding, particularly by cigarette smoking. Accordingly, we sought to examine the role of smoking in generating the relationship between oral health and coronary heart disease in life-long non smokers. Methods and results In the Korean Cancer Prevention Study, 975,685 individuals (349,579 women) aged 30-95 years had an oral examination when tooth loss, a widely used indicator of oral health, was ascertained. Linkage to national mortality and hospital registers over 21 years of follow-up gave rise to 64,784 coronary heart disease events (19,502 in women). In the whole cohort, after statistical adjustment for age, there was a moderate, positive association between tooth loss and coronary heart disease in both men (hazard ratio for seven or more missing teeth vs. none; 95% confidence interval 1.08; 1.02, 1.14; Ptrend across tooth loss groups <0.0001) and women (1.09; 1.01, 1.18; Ptrend 0.0016). Restricting analyses to a subgroup of 464,145 never smokers (25,765 coronary heart disease events), however, resulted in an elimination of this association in men (1.01; 0.85, 1.19); Ptrend 0.7506) but not women (1.08; 0.99, 1.18; Ptrend 0.0086). Conclusion In men in the present study, the relationship between poor oral health and coronary heart disease risk appeared to be explained by confounding by cigarette smoking so raising questions about a causal link.

PMID- 29461087 TI - Ufmylation Is Activated in Vascular Remodeling and Lipopolysaccharide-Induced Endothelial Cell Injury. AB - Vascular remodeling is a key process leading to arterial stenosis. Ufmylation, a novel ubiquitin-like modification, was observed to be associated with many biological processes. However, whether ufmylation is involved in the regulation of vascular remodeling remains unclear. Therefore, the present study focused on the role of ufmylation in vascular remodeling. Mouse femoral artery guidewire injury models were used for inducing vascular remodeling. We found that the expression of Ufm1 was upregulated in hyperplastic neointima. By treating vascular smooth muscle cells (VSMCs) with platelet-derived growth factor BB (PDGF BB) for 3, 6, 12, and 24 h, respectively, we observed that ufmylation was significantly activated in a time-dependent manner. Consistently, the expression levels of Ufc1, Ufl1, and Ufbp1, as key components of the ufmylation system, were all upregulated by PDGF-BB. In contrast, knockdown of Ufm1 expression attenuated PDGF-BB-induced VSMC proliferation. In addition, we observed that ufmylation was activated by lipopolysaccharide (LPS) in endothelial cells, whereas knockdown of Ufm1 was synergized with LPS-induced endothelial cell injury. These findings indicate that ufmylation may participate in regulation of the VSMC phenotypic switch and endothelial cell injury, which may help in the understanding of vascular remodeling. PMID- 29461094 TI - Utilizing neuronavigation for virtual electrode representation and safe resection following SEEG; a technical report. AB - PURPOSE: One of the most effective treatments for epilepsy is resection, but it remains underutilized. Efforts must be made to increase the ease, safety, and efficacy of epilepsy resection to improve utilization. Studies have shown an improved risk profile of stereoelectroencephalography (SEEG) over subdural grids (SDG) for invasive monitoring. One limitation to increased adoption of SEEG at epilepsy centers is the theoretical difficulty of planning a delayed resection once electrodes are removed. Our objective was to develop and present a technique using readily available neuronavigation technology to guide a cortical, non lesional epilepsy resection with co-registration of imaging during invasive monitoring to imaging in an explanted patient, allowing for virtual visualization of electrodes. METHODS: An example case taking advantage of the technique described above as an adjunct for an anatomically guided resection is presented with technical details and images. RESULTS: Intraoperative neuronavigation was successfully used to virtually represent previously removed SEEG electrodes and accuracy could be easily verified by examining scars on the scalp, bone, dura and pia. CONCLUSIONS: The simple technique presented can be a useful adjunct to resection following SEEG. This may help increase the adoption of SEEG, even when resection is planned. PMID- 29461095 TI - Differential Effects of Parental "drug talk" Styles and Family Communication Environments on Adolescent Substance Use. AB - The current study examines the relationships among adolescent reports of parent adolescent drug talk styles, family communication environments (e.g., expressiveness, structural traditionalism, and conflict avoidance), and adolescent substance use. ANCOVAs revealed that the 9th grade adolescents (N = 718) engaged in four styles of "drug talks" with parents (e.g., situated direct, ongoing direct, situated indirect, and ongoing indirect style) and these styles differed in their effect on adolescent substance use. Multiple regression analyses showed that expressiveness and structural traditionalism were negatively related to adolescent substance use, whereas conflict avoidance was positively associated with substance use. When controlling for family communication environments and gender, adolescents with an ongoing indirect style reported the lowest use of substance. The findings suggest implications and future directions for theory and practice. PMID- 29461096 TI - Associations Among Trajectories of Sleep Disturbance, Depressive Symptomology and 24-Hour Urinary Cortisol in HIV+ Women Following a Stress Management Intervention. AB - OBJECTIVE: The burden of sleep disturbance and depressive symptomology is high for persons living with HIV and particularly so for women. While cognitive behavioral stress management (CBSM) is shown to reduce symptoms of depression and 24-hr urinary free cortisol output (CORT) in HIV+ men, less is known about the effects of CBSM on mood and concomitant sleep disturbance in HIV+ women. The study aim is to model longitudinal change in sleep disturbance, depressive symptomology, and CORT for HIV+ women exposed to a 12-week CBSM intervention or control condition. METHODS: Self-reported sleep quality and depressive symptomology, along with CORT, was collected from surveys at baseline and approximately every three months thereafter for nine months from 130 HIV+ women (Mage = 38.44, SD = 7.73). The data was used to specify a parallel process latent growth model with CORT as a time-varying covariate. RESULTS: The model showed acceptable fit. There was a linear decline in sleep disturbance (beta = -0.32, p < .05) and logarithmic decline in depressive symptomology (beta = -0.33, p < .05) for those receiving the intervention. Decline in sleep disturbance predicted lower CORT at nine months. Furthermore, having less depressive symptoms at baseline was associated with lower initial levels of sleep disturbance and greater improvement in sleep quality over time. There was no discernible association between sleep and mood disturbance in the control group. Across groups, there was a consistent association between older age and greater sleep disturbance (r = 0.34, p < .01). CONCLUSION: Sleep disturbance appears to be a behavioral target for CBSM in HIV+ women although older age, preintervention levels of depressive mood, and time-varying levels of CORT output may limit improvement in sleep quality over time. PMID- 29461098 TI - Transcriptional regulators: valuable targets for novel antibacterial strategies. AB - Antibiotics have saved millions of lives over the past decades. However, the accumulation of so many antibiotic resistance genes by some clinically relevant pathogens has begun to lead to untreatable infections worldwide. The current antibiotic resistance crisis will require greater efforts by governments and the scientific community to increase the research and development of new antibacterial drugs with new mechanisms of action. A major challenge is the identification of novel microbial targets, essential for in vivo growth or pathogenicity, whose inhibitors can overcome the currently circulating resistome of human pathogens. In this article, we focus on the potential high value of bacterial transcriptional regulators as targets for the development of new antibiotics, discussing in depth the molecular role of these regulatory proteins in bacterial physiology and pathogenesis. Recent advances in the search for novel compounds that inhibit the biological activity of relevant transcriptional regulators in pathogenic bacteria are reviewed. PMID- 29461099 TI - Trends of Parent-Adolescent Drug Talk Styles in Early Adolescence. AB - The present study seeks to understand how parents as prevention agents approach substance use prevention messages during the period of early adolescence. Students (N = 410) in a drug prevention trial completed surveys from 7th to 9th grade. Using longitudinal data, a series of latent transition analyses was conducted to identify major trends of parent-adolescent drug talk styles (i.e., never talked, situated direct, ongoing direct, situated indirect, and ongoing indirect) in control and treatment conditions. Findings demonstrate a developmental trend in drug talk styles toward a situated style of talk as youth transitioned from 7th grade to 9th grade. Findings also show that even though the drug prevention trial did not specifically target parental communication, parents in the treatment condition provide more ongoing substance use prevention messages to their adolescent children than do parents in the control condition. The present study discusses relevant developmental issues, potential intervention effects, and future research directions for communication research in substance use prevention. PMID- 29461101 TI - The Relationships Between Doctor-Patient Affectionate Communication and Patient Perceptions and Outcomes. AB - The current article combines the literature on doctor-patient communication and affectionate communication. Using Affection Exchange Theory (AET), the study predicts that the need for affection and the benefits of affectionate communication translate to the doctor-patient setting, proposing a series of relationships from both perceived doctor affectionate communication and affection deprivation to several patient outcome variables (patient perception of the doctor, patient communication with the doctor, and patient satisfaction/adherence). The results strongly supported the predictions for both affectionate communication and affection deprivation, with affectionate communication positively relating to most outcome measures and affection deprivation negatively relating to most outcome measures. Affection deprivation served as a moderator for the relationship between provider competence and patient satisfaction, although affectionate communication moderated the relationship between provider competence and patient adherence. Implications and possible directions for future research are discussed. PMID- 29461104 TI - Review of Fluoride Intake and Appropriateness of Current Guidelines. AB - Since the classical epidemiological studies by Dean, it has been known that there should be an optimum level of exposure to fluoride that would be able to provide the maximum protection against caries, with minimum dental fluorosis. The "optimal" daily intake of fluoride for children (0.05-0.07 mg per kilogram bodyweight) that is still accepted worldwide was empirically determined. In the present review, we discuss the appropriateness of the current guidance for fluoride intake, in light of the windows of susceptibility to caries and fluorosis, the modern trends of fluoride intake from multiple sources, individual variations in fluoride metabolism, and recent epidemiological data. The main conclusion is that it is very difficult to think about a strict recommendation for an "optimal" range of fluoride intake at the individual level in light of existing knowledge of 1) the mechanisms of action of fluoride to control caries, 2) the mechanisms involved in dental fluorosis development, 3) the distinct factors that interfere in the metabolism of fluoride, and 4) the windows of susceptibility to both dental caries and fluorosis development. An "optimal" range of fluoride intake is, however, desirable at the population level to guide programs of community fluoridation, but further research is necessary to provide additional support for future decisions on guidance in this area. This list includes the effect of factors affecting fluoride metabolism, clinical trials on the effectiveness of low-fluoride dentifrices to prevent caries in the primary dentition, and validation of biomarkers of exposure to fluoride.

AB - Impaired cognitive control is a consequence of cocaine exposure. Difficulty with feedback processing may underlie this impairment. We examined neural correlates of feedback processing using event-related potentials (ERPs) in 49 prenatally cocaine-exposed (PCE) and 34 nondrug exposed (NDE) adolescents. Adolescents performed a reward-feedback task with win/no-win feedback in a chance-based task. We investigated amplitude and latency of the feedback-related negativity (FRN) and P300 ERP components and source-based estimates elicited during feedback processing. PCE adolescents had smaller P300 amplitudes for no-win feedback, and source analysis in the P300 time window revealed differences between groups localized to the dorsal anterior cingulate cortex. PMID- 29461106 TI - Current Guidance for Fluoride Intake: Is It Appropriate? AB - The purpose of this report is to examine critically the appropriateness of the current guidance for fluoride intake in the population (0.05-0.07 mg F/kg bodyweight/d), consider whether changes to the current guidance are desirable, and suggest further research that will strengthen the evidence base for future decisions on guidance/advice in this area. The benefits and the risks of using fluoride particularly concern preschool children because it is at this age that excessive fluoride intake may result in dental fluorosis. Data from mostly cross sectional studies show a wide variation in exposure and a considerable variation in the amount of fluoride ingested. Fluorosis, mostly mild, is commonly observed. For considering changes in current guidance, there is a need for more knowledge on the relationship between exposure to fluoride at an early age and the development of fluorosis. For that, prospective epidemiological studies with sufficiently large and representative samples of children are required. It is also important to study children in communities both with and without water fluoridation and to include populations where salt or milk fluoridation is used. There is also a need for professional agreement on acceptable levels of mild and moderate/severe fluorosis and a more comprehensive knowledge on the appreciation of mild fluorosis among the public.

PMID- 29461108 TI - Understanding Optimum Fluoride Intake from Population-Level Evidence. AB - Policy on fluoride intake involves balancing caries against dental fluorosis in populations. The origin of this balance lies with Dean's research on fluoride concentration in water supplies, caries, and fluorosis. Dean identified cut points in the Index of Dental Fluorosis of 0.4 and 0.6 as critical. These equate to 1.3 and 1.6 mg fluoride (F)/L. However, 1.0 mg F/L, initially called a permissible level, was adopted for fluoridation programs. McClure, in 1943, derived an "optimum" fluoride intake based on this permissible concentration. It was not until 1944 that Dean referred to this concentration as the "optimal" concentration. These were critical steps that have informed health authorities through to today. Several countries have derived toxicological estimates of an adequate and an upper level of intake of fluoride as an important nutrient. The US Institute of Medicine (IOM) in 1997 estimated an Adequate Intake (AI) of 0.05 mg F/kg bodyweight (bw)/d and a Tolerable Upper Intake Level (UL) of 0.10 mg F/kg bw/d. These have been widely promulgated. However, a conundrum has existed with estimates of actual fluoride intake that exceed the UL without the expected adverse fluorosis effects being observed. Both the AI and UL need review. Fluoride intake at an individual level should be interpreted to inform more nuanced guidelines for individual behavior. An "optimum" intake should be based on community perceptions of caries and fluorosis, while the ultimate test for fluoride intake is monitoring caries and fluorosis in populations.

AB - A group of 126 typically developing children (aged 5-12 years) completed three cool executive function tasks (spatial working memory, stop signal, intra-extra dimensional shift), two hot executive function tasks (gambling, delay of gratification), one advanced theory of mind task (strange stories with high versus low affective tone), and a vocabulary test. Older children performed better than younger children, consistent with the protracted development of hot and cool executive functions and theory of mind. Multiple regression analyses showed that hot and cool executive functions were correlated but they predicted theory of mind in different ways. PMID- 29461112 TI - "Self" Takes it All in Mental Illness: Examining the Dynamic Role of Health Consciousness, Negative Emotions, and Efficacy in Information Seeking. AB - Mental illness such as depression, stress, and anxiety disorder is prevalent in our everyday lives. Yet, little is known about how health-related variables operate in the mental illness context. Centering on health consciousness, this study systematically examines how health consciousness affects information seeking and whether negative emotions and efficacy intervene in the relationship in mental illness. The results of the survey (N = 614) suggest that health consciousness relates to fear, anxiety, self-efficacy, and response efficacy but does not relate to information seeking. Interestingly, self-efficacy is the only mediator in the relationship between health consciousness and information seeking on mental illness. Implications are discussed.

PMID- 29461114 TI - Picture Yourself Healthy-How Users Select Mediated Images to Shape Health Intentions and Behaviors. AB - Hypotheses on how selective viewing of mediated images may sustain eating habits and aid healthier eating were derived from the Selective Exposure Self- and Affect Management model. The model posits that individuals select to view media to manage their self-concepts-and that this exposure affects subsequent intentions and behaviors. Participants (N = 265) selectively viewed Instagram like postings featuring healthy or unhealthy food imagery. Beforehand, participants reported habits and perceived expert recommendations regarding food intake. After viewing postings, participants chose gift cards representing healthy or unhealthy food purchases and indicated food intake intentions. Results show that existing eating behavior predicts selective exposure to healthy or unhealthy food imagery, which in turn shapes gift card choices and (both healthy and unhealthy) food intake intentions. PMID- 29461118 TI - Emotional face recognition in individuals withattention-deficit/hyperactivity disorder: a review article. AB - This review focuses on facial emotion recognition (FER) in individuals with attention- deficit/hyperactivity disorder (ADHD). Behavioral studies of FER in ADHD have resulted in inconsistent findings. Here, we discuss the factors that vary across studies and the way that they influence FER processes in ADHD. Across reviewed studies, fear was the most deficient facial expression to be recognized. Our review suggested that FER deficit in ADHD does not alleviate across development and is partially distinct from ADHD symptoms. In conclusion, assessment of FER in ADHD and targeting that in interventional plans could lead to social skills improvement in ADHD. PMID- 29461119 TI - Reconsidering the relation between serum homocysteine and red blood cell distribution width: a cross-sectional study of a large cohort. AB - PURPOSE: In a recent small sample study, red blood cell distribution width (RDW) was suggested as a predictor of homocysteine levels. The current study was aimed to reexamine this association in a large scale sample. METHODS: A retrospective cross-sectional study of healthy adults, conducted at Rabin Medical Center, during 2000-2014. Data were retrieved from the medical charts and a logistic regression controlling for interfering factors was carried out. Sensitivity analysis was implemented by exclusion of individuals with anaemia. RESULTS: Five thousand, five hundred fifty-four healthy individuals were included. Mean serum homocysteine level was 10.10 (SD 2.72) MUmol/L. 34.4% of the study population had a homocysteine level higher than the upper limit of normal (10.8 MUmol/L). Homocysteine showed no association with RDW (OR 1.00; 95% CI 0.97-1.03), but increased with age (OR 1.05; 95% CI 1.04-1.06) and decreased with a rise in haemoglobin (OR 0.77; 95% CI 0.71-0.83), and in the mean corpuscular volume (OR 0.86; 95% CI 0.85-0.88). Exclusion of individuals with anaemia did not reveal an association between homocysteine and RDW but found a somewhat smaller association between haemoglobin and RDW [OR 0.82; 95% CI 0.73-0.91]. CONCLUSIONS: In our large scale sample we did not find an association between RDW and serum homocysteine. PMID- 29461121 TI - Topical 3% tranexamic acid enhances the efficacy of 1064-nm Q-switched neodymium doped yttrium aluminum garnet laser in the treatment of melasma. AB - BACKGROUND: A QS-NdYAG laser (QSNYL) and topical tranexamic acid (TA) have been widely used. However, no study has yet reported the efficacy of using both QSNYL and TA as a combined treatment for melasma. OBJECTIVES: To evaluate the efficacy and adverse effects of topical 3% TA combined with 1064-nm QSNYL as a treatment for melasma. METHODS: A randomized, prospective, split-face, controlled trial was conducted. A 1064-nm QSNYL was performed on the entire face at baseline and 4 weeks later. The participants were randomly selected for application of topical 3% TA on one side of the face and the vehicle treatment on the other side of the face for 8 weeks. Clinical responses were determined by mMASI scores, MexameterTM, and participants' evaluation. RESULTS: Twenty-five participants completed the study. At the end of the study, the mMASI score significantly decreased in the combination treatment (p < 0.05), while no significant changes were observed in the laser-alone treatment. More than 80% of the participants noticed a >50% improvement on the side with combination therapy at every follow up visit. No serious adverse events were reported. CONCLUSION: Topical TA as an adjuvant demonstrated trends of better outcomes than QSNYL alone for the treatment of melasma. PMID- 29461120 TI - Follicle-stimulating hormone peptide-conjugated nanoparticles for targeted shRNA delivery lead to effective gro-alpha silencing and antitumor activity against ovarian cancer. AB - The distinct hormone molecules and receptors, such as follicle-stimulating hormone receptor (FSHR) in ovarian cancer, provide opportunities for more precisely targeted therapy. We previously developed FSHR-mediated nanoparticles and found that FSH peptides on the surface of nanoparticles improved the delivery of short interfering RNA (siRNA) into ovarian cancer cells. However, the high toxicity of the nanoparticles and the transient silencing of the siRNA in vivo limited further study. Here, we developed FSH peptide-conjugated nanoparticles with an increased amount of polyethylene glycol (PEG) grafting and encapsulated short hairpin RNA (shRNA) to silence the target gene, growth-regulated oncogene alpha (gro-alpha). The nanoparticle complexes exhibited good stability over three weeks. Expression of the target gene, gro-alpha, was significantly down-regulated by gro-alpha shRNA-loaded nanoparticles conjugated with FSH peptides (FSH33-G-NP) in FSHR-positive HEY cells. Cell proliferation, migration, and invasion were also inhibited by FSH33-G-NP. Tumor growth was delayed significantly in the mice treated with FSH33-G-NP. No significant loss of body weight or severe toxic effects were observed in any groups. In conclusion, gro-alpha shRNA-loaded nanoparticles conjugated with FSH peptides overcame the drawbacks of the in vivo application of RNAi therapeutics and polymer-based nanocarriers and showed safe antitumor efficacy. Our study might contribute to the application of FSHR-based targeted therapy and imaging in cancer.

PMID- 29461125 TI - The long-term effect of pulsed dye laser on Necrobiosis Lipoidica: A case study. AB - A 57-year-old female was presented with an irrepressible case of Necrobiosis Lipoidica considering the possibility of a surgical skin graft. Instead, a pulsed dye laser treatment was used as an alternate treatment. Previous case studies have been found in the literature on the effect of pulsed dye laser on Necrobiosis Lipoidica. The use of a pulsed dye laser in this case resulted in rendering the lesions asymptomatic for pain and a reduction in volume. Prolonged control was exhibited. From this case, we conclude that pulsed dye laser therapy is effective when increasing the number of treatments of laser therapy, and can be used as a treatment for Necrobiosis Lipoidica. PMID- 29461124 TI - Improving mandibular contour: A pilot study for indication of PPLA traction thread use. AB - BACKGROUND: The request for less-aggressive procedures to improve mandibular contour is increasing. Several kinds of threads have been used for this purpose. Nevertheless, PLLA (poly-L-Lactic acid) traction thread procedure has not been previously described. AIM: To investigate the role of PLLA traction threads in improving mandibular contour. METHODS: Twenty women were enrolled in the study. They were differentially classified for skin laxity. Patients were treated in a single session with two PLLA traction threads per side. Specific post-procedure instructions were given to patients, and complications occurred after the procedures were estimated. A Fisher's t-test was performed to identify criteria related to longevity of results. RESULTS: We found longevity of results to be associated with younger age (p = 0.001), absence of severe skin laxity of jawline and neck (p = 0.001), and aesthetic satisfaction (p = 0.024). Edema, swelling, and temporary skin contour irregularities were found in most cases (N = 16; 80%), whereas paresthesia resolving without sequelae in 2-4 weeks was found in two cases (10%). CONCLUSIONS: Our results show that selected patients, younger than 51 and showing a mild-moderate degree of skin laxity of jawline and neck angle represent ideal candidates for PLLA traction thread treatment. Further studies will be performed to confirm our results. PMID- 29461122 TI - Synchronous delivery of oxygen and photosensitizer for alleviation of hypoxia tumor microenvironment and dramatically enhanced photodynamic therapy. AB - Photosensitizer, proper laser irradiation, and oxygen are essential components for effective photodynamic therapy (PDT) in clinical cancer therapy. However, native hypoxic tumoral microenvironment is a major barrier hindering photodynamic reactions in vivo. Thus, we have prepared biocompatible liposomes by loading complexes of oxygen-carrier (hemoglobin, Hb) and photosensitizer (indocyanine green, ICG) for enhanced PDT against hypoxic tumor. Ideal oxygen donor Hb, which is an oxygen-carried protein in red blood cells, makes such liposome which provide stable oxygen supply. ICG, as a photosensitizer, could transfer energy from lasers to oxygen to generate cytotoxic reactive oxygen species (ROS) for treatment. The liposomes loading ICG and Hb (LIH) exhibited efficient tumor homing upon intravenous injection. As revealed by T2-weighted magnetic resonance imaging and immunohistochemical analysis, the intratumoral hypoxia was greatly alleviated, and the level of hypoxia inducible factor-1alpha (HIF-1alpha) and vascular endothelial growth factor (VEGF) in tumor was obviously down-regulated. A weak PDT efficiency was found in cells incubated in simulated hypoxia condition in vitro, while PDT effect was dramatically enhanced in LIH treated hypoxia cells under near-infrared (NIR) laser, which was mainly attributed to massive generation of ROS with sufficient oxygen supply. ROS trigger oxidative damage of tumors and induce complete suppression of tumor growth and 100% survival rate of mice, which were also in good health condition. Our work highlights a liposome based nanomedicine that could effectively deliver oxygen to tumor and alleviate tumor hypoxia state, inducing greatly improved efficacy compared to conventional cancer PDT and demonstrates the promise of modulating unfavorable tumor microenvironment with nanotechnology to overcome limitations of cancer therapies. PMID- 29461126 TI - Network and Individual Factors Associated with Drug Use among Female Sex Workers (FSWs) in Southern China: A Mixed-Method Approach. AB - Research on women who engage both in drug use and sex work has been limited, as most previous studies have focused on these risk behaviors separately. The current study examines the network properties as well as the demographic and behavioral factors associated with drug use among female sex workers (FSWs) in southern China. We collected survey data (n = 175) in the Hainan province during our 26 months of ethnographic fieldwork in China. Our analyses included Fisher's exact chi-square tests, independent-samples t-tests, Mann-Whitney U, binary logistic regression (LR), as well as ethnographic data analysis. Multivariate analysis showed that women who were younger age, single, more educated, and earning a higher income were more likely to use drugs. Pertaining to network properties, FSWs with a lower percentage of long-term clients (and men) in ego networks were more likely to use drugs; this would imply a mechanism by which drug-using FSWs are more at risk, as the women take a greater number of transient clients. In addition, FSWs who were influential network members (i.e., higher betweenness centrality) and were closely related to other network members (i.e., higher closeness centrality) were more likely to use drugs; this may suggest that drug use is a means of sustaining the high functionality of the workers. Our ethnographic data also showed that club drug use was easily accessible in entertainment venues and was often a means of socialization in FSW communities. Network characteristics correlated to HIV-related risks among FSWs should be further examined in future studies. PMID- 29461127 TI - MIBI scintigraphy of parathyroid adenomas: correlation with biochemical and histological markers. AB - PURPOSE: In this study, we tested the hypothesis that MIBI-positive and MIBI negative adenomas of parathyroid glands (APGs) have distinct biochemical and histological markers that could help differentiate MIBI-positive from MIBI negative APGs. PATIENTS AND METHODS: 40 patients with 41 APGs were included in the study. Patients were enrolled in the study after MIBI scintigraphy examinations had been carried out. Biochemical analyses included serum levels of calcium (Ca), intact parathyroid hormone (iPTH), and 25-hydroxyvitamin D3 (25-OH D3). All patients had neck ultrasound and MIBI examinations. After surgical resection the APGs were examined histologically. RESULTS: In each of 39 patients one APG could be confirmed by histology, and in one patient, two contralateral APGs were identified. MIBI studies were positive in 73 % and negative in 27 % of the APGs. False-positive cases were not observed. MIBI-negative APGs were only present in patients with iPTH values below 150 pg/ml. In 82 % of MIBI negative studies oxyphilic cells were absent, and this cell type was present in only 18 % of MIBI negative cases (p < 0.001). Regarding cysts within the APGs, no differences were demonstrated between MIBI positive or negative studies (p = 0.32). Fat cells were seen in none of the MIBI -negative studies and in only 3 % of MIBI positive studies (p = 0.08). CONCLUSIONS: For APGs, MIBI positivity correlates with serum iPTH concentration. The absence of oxyphilic cells with large numbers of mitochondria in APGs contributes to MIBI negativity, probably because of the reduced binding sites for the radiotracer. PMID- 29461128 TI - Ocular complications after cosmetic periocular diode laser application to the eyelids. AB - A 25-year-old woman underwent diode laser application on the both upper eyelids in the dermatology department of a private hospital to obtain a cosmetic healing of the reddish look on her eyelids without any protective lenses. The patient experienced severe uveitis, atonic pupils, raised intraocular pressure, and increased sensitivity to light in her eyes on the following day of the procedure. Topical steroids and pressure-lowering agents were able to treat the acute uveitis and glaucoma, unfortunately the patient suffered from irreversible atonic and atrophic pupils and photosensitivity. It is recommended that cosmetic laser application on the periocular area should be avoided, and if it is still to be performed, it should be applied cautiously and the patient should be informed of the potential ocular complications. PMID- 29461129 TI - Functioning and primary healthcare utilization in older adults: a 1-year follow up study. AB - BACKGROUND/PURPOSE: Older adults are high users of healthcare services, mainly due to health conditions and their impact on daily activities, challenging the ability of health systems to provide timely and high-quality care. Conceivably, using disability-related variables to predict future healthcare utilization could contribute to reduce both older adults' disability and healthcare costs. This study aimed to explore the association between aspects of disability and older adults' primary healthcare utilization and hospitalization over a period of 1 year. METHODS: Older adults (n = 129) were assessed for self-reported disability, lower limb performance, pain intensity and number of painful body sites, depressive symptoms, and self-reported physical activity. Data on primary healthcare utilization and hospitalization were collected for the period of 1 year through registries and phone interviews. RESULTS: Regression analysis, adjusted for potential confounders, showed that self-reported disability and pain intensity were significantly associated with total primary healthcare utilization and together with a confounding variable (number of chronic conditions) explained 16% of its variance (p < 0.05). Increased physical activity was significantly associated with a decreased likelihood of being admitted to hospital (95% CI for exponentiation (B) = 0.27-0.81). DISCUSSION: Data suggest that decreasing self reported disability and increasing physical activity may decrease primary healthcare utilization and hospitalization, respectively. PMID- 29461130 TI - Treatment of facial telangiectasia with narrow-band intense pulsed light in Chinese patients. AB - OBJECTIVE: To evaluate the efficacy and safety of narrow-band intense pulsed light (DPL) in treating facial telangiectasia. METHOD: Thirty patients with facial telangiectasia underwent five sessions of treatment with DPL (500 nm~600 nm) at 4-week interval. The erythema index (EI), temperature, transepidermal water loss (TEWL), and lightness of the skin (L) were measured before each treatment session and at each follow-up. RESULT: Thirty cases completed treatment and follow-ups. Twenty-seven cases (90%) got more than 50% clearance post treatment and among them eight cases (27%) got more than 75% clearance. The average of the mean EI value decreased with the number of treatment sessions; the EI observed after two treatment sessions was significantly different from that observed before treatment (P = 0.012, P < 0.05). The decrease in skin temperature and TEWL values post-treatment was statistically significant (P = 0.000, P = 0.027, P < 0.05), while the L value increased significantly (P = 0.025, P < 0.05). Thirty percent cases had reccurence at 6-month follow-up. While burning sensation, erythema, and swelling were usually seen during the treatment, no severe side effects were observed during treatment and follow-ups. CONCLUSION: Narrow-band intense pulsed light DPL is effective and safe in treating facial telangiectasia. PMID- 29461131 TI - Interprofessional transformation of clinical education: The first six years of the Veterans Affairs Centers of Excellence in Primary Care Education. AB - This paper describes the Centers of Excellence in Primary Care Education (CoEPCE), a seven-site collaborative project funded by the Office of Academic Affiliations (OAA) within the Veterans Health Administration of the United States Department of Veterans Affairs (VA). The CoEPCE was established to fulfill OAA's vision of large-scale transformation of the clinical learning environment within VA primary care settings. This was accomplished by funding new Centers within VA facilities to develop models of interprofessional education (IPE) to teach health professions trainees to deliver high quality interprofessional team-based primary care to Veterans. Using reports and data collected and maintained by the National Coordinating Center over the first six years of the project, we describe program inputs, the multicomponent intervention, activities undertaken to develop the intervention, and short-term outcomes. The findings have implications for lessons learned that can be considered by others seeking large-scale transformation of education within the clinical workplace and the development of interprofessional clinical learning environments. Within the VA, the CoEPCE has laid the foundation for IPE and collaborative practice, but much work remains to disseminate this work throughout the national VA system. PMID- 29461132 TI - Heavy Alcohol Use Among Migrant and Non-Migrant Male Sex Workers in Thailand: A Neglected HIV/STI Vulnerability. AB - BACKGROUND: There is scarce research on male sex workers in the context of alcohol use. While heavy alcohol use has been established as a risk factor for HIV and STI infections among men who have sex with men (MSM), men who engage in sex work with other men, particularly from the Global South, have not been included in these studies. Moreover, studies among male sex workers in Asia often do not explore migration contexts of these men. OBJECTIVES: The objective of this exploratory study is to examine the prevalence and correlates of heavy alcohol use among migrant and non-migrant male sex workers in Bangkok and Pattaya, Central Thailand. METHODS: Between August and October 2015, 18-24 year-old migrant and non-migrant male sex workers (n = 212) were recruited from various male sex work-identified venues (bars, clubs, massage parlors, and go-go bars) to take an interviewer-administered cross-sectional survey in Bangkok and Pattaya, Thailand. Measures were adapted from previous studies in similar populations and included structured questions across four domains, including demographic characteristics, alcohol use, stimulant use, and sexual behaviors. Multivariable logistic regression assessed the independent associations between heavy alcohol use (heavy versus not heavy) and demographic characteristics, stimulant use and sexual behavior. RESULTS: Heavy alcohol use was prevalent among one-third of participants. Heavy alcohol use was positively associated with male sex workers who were non-migrant and Thai, currently using stimulants, having 15 or more male clients in the past month and having first consumed alcohol at age 15 years or younger. CONCLUSIONS: Current HIV prevention efforts should consider subpopulations of MSM, including male sex workers and migrants, as well as other risk behaviors like alcohol, as important contexts for HIV and STI risks. PMID- 29461133 TI - Natural options for management of melasma, a review. AB - A blemish free, even-toned skin is universally associated with healthy skin. This reasoning makes people desire to have a flawless skin. Melanin is a naturally occurring pigment in humans. This pigment is responsible for skin, hair, and eye color, therefore determines our race and phenotypic appearance. On darker skin types, it is common that melanin production processes malfunctions. These malfunctions often lead to overproduction and secretion of melanin. As a result, unwanted pigmentary problems such melasma occur. Due to unknown etiology and its recurrence in nature, melasma is challenging to treat. The current available melasma treatment options often produce undesired side effects and suboptimum results. First-line topical treatments usually involve hydroquinone or topical steroids. Apart from the irritant reactions, this treatment mode is not suitable for all skin types. Skin care specialists are in search of an effective long-term cosmetics and cosmeceuticals to address hypermelanosis problems. Understanding of naturally occurring depigmenting agents provides an opportunity for more effective ways to manage melasma in all skin types. This review considers the benefits of naturally occurring ingredients which could help address skin pigmentation problems and broaden the choice for skin-lightening treatments. PMID- 29461134 TI - Correlates of Validity of Self-Reported Methamphetamine Use among a Sample of Dependent Adults. AB - BACKGROUND: Self-reported data are widely used in substance-use research, yet few studies have assessed the validity of self-reported methamphetamine use compared to biological assays. OBJECTIVES: We sought to assess the validity and correlates of validity of self-reported methamphetamine use compared to urine toxicology (UTOX). METHODS: Using a sample of methamphetamine-dependent individuals enrolled in a randomized controlled pharmacotherapy trial in the United States (n = 327 visits among 90 participants), we calculated sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and the kappa coefficient of self-reported methamphetamine use in the past 3 days compared to UTOX, as well as the NPV of self-reported methamphetamine use over an extended recall period of 1 month. We used multivariable logistic regression models to assess correlates of concordance between self-reported methamphetamine use and UTOX. RESULTS: The sensitivity of self-reported methamphetamine use in the past 3 days was 86.7% (95% confidence intervals (95%CI): 81.4%-91.4%), the specificity was 85.3% (77.7-91.3), the PPV was 91.5% (86.9-94.8), and the NPV was 78.0% (69.4 86.1), compared to UTOX (kappa = 0.71). The NPV over the extended recall period was 70.6% (48.0-85.7). In multivariable analyses, validity of self-reported methamphetamine use was higher for older participants but lower during follow-up compared to baseline and when polysubstance use or depressive symptoms were reported. Conclusions/Importance: Our sample of methamphetamine-dependent adults reported recent methamphetamine use with high validity compared to UTOX. Validity increased with age but decreased when participants reported depressive symptoms or polysubstance use as well as later in the study timeline and during longer recall periods. PMID- 29461135 TI - Teamwork and Adherence to Recommendations Explain the Effect of a Care Pathway on Reduced 30-day Readmission for Patients with a COPD Exacerbation. AB - This study aimed to increase our understanding of processes that underlie the effect of care pathway implementation on reduced 30-day readmission rate. Adherence to evidence-based recommendations, teamwork and burnout have previously been identified as potential mechanisms in this association. We conducted a secondary data analysis of 257 patients admitted with chronic obstructive pulmonary disease exacerbation and 284 team members caring for these patients in 19 Belgian, Italian and Portuguese hospitals. Clinical measures included 30-day readmission and adherence to a specific set of five care activities. Teamwork measures included team climate for innovation, level of organized care and burnout (emotional exhaustion, level of competence and mental detachment). Care pathway implementation was significantly associated with better adherence and reduced 30-day readmission. Better adherence and higher level of competence were also related to reduced 30-day readmission. Only better adherence fully mediated the association between care pathway implementation and reduced 30-day readmission. Better team climate for innovation and level of organized care, although both improved after care pathway implementation, did not show any explanatory mechanisms in the association between care pathway implementation and reduced 30-day readmission. Implementation of a care pathway had an impact on clinical and team indicators. To reduce 30-day readmission rates, in the development and implementation of a care pathway, hospitals should measure adherence to evidence-based recommendations during the whole process, as this can give information regarding the success of implementation. PMID- 29461136 TI - Working With Clients With Limited English Proficiency: Mapping Language Access in Occupational Therapy. AB - Nearly one in ten US residents have difficulty speaking and understanding English and are deemed to have limited English proficiency (LEP). Despite federal mandates for provision of interpreters and other language access services, individuals with LEP experience notable health disparities. Occupational therapists must be prepared to equitably serve this population, however there is a dearth of research evidence and practical recommendations about our profession's readiness to serve this growing population. This paper maps the current healthcare policy environment and existing language access research relevant to occupational therapy. Implications for the future of occupational therapy research, education and practice are discussed. PMID- 29461137 TI - Getting on the same page: an interprofessional common reading program as foundation for patient-centered care. AB - A primary goal of interprofessional education is to produce clinicians who practice collaboratively to provide patient-centered care. This exploratory study evaluated whether students' attitudes about a literary account of an illness experience endured after a year of professional and clinical education and if students applied lessons learned from a common reading to the delivery of patient centered care. Six focus groups were completed with health professions students and five main themes emerged from the focus group data. Themes include: Seeing family members as stakeholders; Establishing common ground with peers and the larger reason for graduate school; Applying lessons to clinical practice that see the patient as a person; Experiencing an emotional connection with a story and its characters; and Taking alternative perspectives/stepping into the shoes of the patient. Study results are discussed in relation to the interprofessional education literature, with implications for educators and interprofessional curricula also presented. We conclude that a common reading program may provide an effective means for developing health professions students' knowledge and attitudes in the tenets of patient-centered collaborative care. It has the potential to build community through shared intellectual experience, facilitating meaningful reflection and perspective-taking in interprofessional learners. PMID- 29461138 TI - Enablers and barriers to the development of interprofessional collaboration between physicians and osteopaths: A mixed methods study. AB - Osteopathy is a complementary and alternative medicine (CAM) that is growing in popularity. Increasing numbers of parents are seeking pediatric osteopathic care in addition to conventional medical care. Information about the development of interprofessional collaboration (IPC) between these practitioners is scarce. This explanatory sequential mixed methods study aimed to explore enablers of and barriers to the development of IPC between physicians and osteopaths involved with pediatric patients in primary care in Quebec, Canada. Postal questionnaires about collaborative practices were first sent to all physicians and osteopaths working with pediatric patients in Quebec. Semi-structured individual interviews were then conducted with a subset of 10 physicians and 11 osteopaths. A total of 274 physicians (14%) and 297 osteopaths (42%) completed the survey. Forty-five percent (n = 122) of physicians reported that they referred at least one pediatric patient per month to an osteopath. Thirty-six percent (n = 96) of physicians and 41% (n = 122) of osteopaths indicated having professional relationships. Personal consultation, professional relationship, perceived utility of osteopathy and community practice were positively associated with osteopathic referrals. According to participants, the strongest enabler of the development of collaboration was positive clinical results reported by parents. Additional enablers included the osteopath having previous health professionals training such as physiotherapist, pediatric experience, mutual respect for professional boundaries and complementarity, perceived safety of osteopathy, and parents' requests for collaboration. Barriers were the absence of a common language, the organizational and legal context, uncertainty regarding one another's roles, lack of interprofessional interactions, and limited scientific evidence. These results related to enablers of and barriers to collaboration between physicians and osteopaths and the illustration of their dynamic interaction could be used to guide efforts to promote productive collaboration and safe patient-oriented care. PMID- 29461139 TI - Placebo effect of facilitatory Kinesio tape on muscle activity and muscle strength. AB - PURPOSE: Kinesio tape (KT) is claimed to be able to facilitate muscle activation and promote muscle strength. Previous studies have proposed that placebo effect could be a major attributing factor. This study sought to compare the effects of facilitatory KT on muscle activity and performance between regular KT-users and non-users. METHODS: Sixty participants, including 27 regular KT-users and 33 non users, performed maximal grip assessment with and without facilitatory KT, which was applied to their wrist extensor muscles of the dominant forearm from the direction of origin to insertion at 75% of its maximal tension. Within-subject comparisons of normalized root mean square of the wrist extensors electromyographic activity, maximal grip strength, and perceived performance were conducted. RESULTS: KT-users showed an increase in grip strength with application of facilitatory KT, when compared to tapeless condition (p = 0.030, Cohen's d = 0.16). Non-users demonstrated similar grip strength with and with KT application (p = 0.232). No significant differences were found in the muscle activity (p > 0.198) and perceived performance (p > 0.400) in both groups. CONCLUSIONS: Facilitatory KT promotes maximal grip strength only among regular KT users, but its effect is trivial. Interestingly, such effect is not related to any electrophysiological change in the KT applying muscle, which may indicate an indirect working mechanism leading to the increased grip strength. PMID- 29461140 TI - Genetic investigation of ocular developmental genes in 52 patients with anophthalmia/microphthalmia. AB - BACKGROUND: Mutation in eye developmental genes has been reported to cause anophthalmia and microphthalmia. However, in India, especially in the Western Indian population, such reports are scarce. Hence, the present study aims to investigate mutations in 15 ocular developmental genes in patients with anophthalmia and microphthalmia in the western region of India. MATERIALS AND METHODS: Genomic DNA was isolated from the blood of 52 individuals affected with microphthalmia and anophthalmia, and 50 healthy normal controls. Polymerase chain reaction (PCR) was carried out for 15 genes including BMP4, CRYBA4, FOXE3, GDF6, GJA3, GJA8, MITF, OTX2, PAX6, PITX3, RAX, SIX3, SIX6, SOX2, and VSX2 using gene specific primers spanning the exon-intron boundaries and part of a promoter region. The amplified PCR products were purified and then subjected to Sanger's bi-directional sequencing. Nucleotide variations were examined using a basic local alignment search tool (BLAST). RESULTS: Bi-directional sequencing identified 8 novel and 14 known variations. Out of this, the variations GJA3 c.92T>A; p.Ile31Asn, SOX2-c.542C>A; p.Pro181Gln and SOX2-c.541_542delinsGA; p.Pro181Glu were found to be deleterious by in silico analysis. The GJA3 p.Ile31Asn mutation was identified in a patient with bilateral microphthalmia, microcornea, and membranous cataract. The SOX2-p.Pro181Gln and SOX2-p.Pro181Glu mutations were identified in patients with isolated bilateral microphthalmia and microphthalmia with microcornea, respectively. A novel nondeleterious missense variation was identified in the GJA8 gene in a patient with anophthalmia. CONCLUSION: These results support the crucial role of GJA3 and SOX2 in eye development and indicate a detailed functional study to understand the molecular mechanisms underlying the disease pathology.

PMID- 29461142 TI - Reweighting anthropometric data using a nearest neighbour approach. AB - When designing products and environments, detailed data on body size and shape are seldom available for the specific user population. One way to mitigate this issue is to reweight available data such that they provide an accurate estimate of the target population of interest. This is done by assigning a statistical weight to each individual in the reference data, increasing or decreasing their influence on statistical models of the whole. This paper presents a new approach to reweighting these data. Instead of stratified sampling, the proposed method uses a clustering algorithm to identify relationships between the detailed and reference populations using their height, mass, and body mass index (BMI). The newly weighted data are shown to provide more accurate estimates than traditional approaches. The improved accuracy that accompanies this method provides designers with an alternative to data synthesis techniques as they seek appropriate data to guide their design practice.Practitioner Summary: Design practice is best guided by data on body size and shape that accurately represents the target user population. This research presents an alternative to data synthesis (e.g. regression or proportionality constants) for adapting data from one population for use in modelling another. PMID- 29461143 TI - ?

AB - On-pack tobacco warnings typically feature long-term health risks, which many young adults rationalize or reject. We examined the emotions generated by more proximal warnings to see if we could identify common features among the most effective warnings. Respondents in a sample of 474 smokers and 476 susceptible non-smokers used a modified Geneva Emotion Wheel (GEW) to assess cigarette packs displaying 12 test warnings and one current warning. The strongest emotions aroused in smokers were disgust, disappointment, and regret. Three warnings showing the effect of smoking on babies and animals had significantly higher emotional potency scores than a current health warning. Among susceptible non smokers, warnings showing harm to animals, child labor, and a dying smoker had the highest emotional potency. Stronger negative emotions were elicited from both smokers and susceptible non-smokers by warnings that featured more proximal outcomes than are typically shown in on-pack tobacco warnings. On-pack warnings that resonate with young people, the group most at risk of smoking and most likely to benefit from quitting, could promote cessation and deter initiation more effectively than warnings depicting long-term health outcomes. The GEW could be used to screen potential warning images to identify those most likely to be worth evaluating. PMID- 29461153 TI - The Role of Masculinity and Depressive Symptoms in Predicting Suicidal Ideation in Homeless Men. AB - Men's suicide rates may be influenced by difficulties recognizing externalizing depressive symptoms in men that adhere to hegemonic masculine gender role norms. The purpose of this study was to investigate the ability of externalizing depressive symptoms, internalizing depressive symptoms, and hegemonic masculinity in predicting the existence and severity of suicidal ideation. Homeless men (n = 94) completed questionnaires at a resource center in the Rocky Mountain Western United States. Internalizing symptoms predicted the existence of suicidal ideation, and both externalizing and internalizing symptoms predicted increased severity of suicidal ideation. The masculine norms violence and playboy were correlated with men's suicidal ideation. An externalizing-internalizing model of predicting suicide in men and men's adherence to certain masculine gender role norms may be valuable to further efforts in suicide assessment and prevention.

While a number of studies applying different approaches regarding polypill have been performed, none of them has had a focus on stroke as the main outcome. A combination pill containing drugs such as statins, diuretics, and other antihypertensives is currently available in various formats. Estimates focusing mostly on primary prevention show that using such a combination drug a reduction in the 5-year stroke incidence by 50% can be achieved - especially in low- and middle-income countries with a high prevalence of risk factors even among people at young ages. A combination of a large supporting population-wide program with a registry-based quality control is the most likely perspective and can be achieved within a reasonable time frame and potentially have significant influence in young stroke populations.

AB - CASE DESCRIPTION A 7-year-old 44-kg (97-lb) neutered male Great Pyrenees was referred for evaluation because of episodic dyspnea with cyanosis of 1 to 2 weeks' duration. Three days prior to evaluation, the clinical signs had worsened, including 1 episode of collapse. CLINICAL FINDINGS Thoracic radiography and CT revealed a well-delineated soft tissue mass, located approximately 1.5 cm cranial to the carina and occupying almost 90% of the tracheal lumen. A CBC and serum biochemical analysis were performed, and all results were within reference limits. TREATMENT AND OUTCOME Tracheoscopy confirmed the presence of a broad based bilobate mass that was protruding from the right dorsal aspect of the trachea and occupied almost the entire tracheal lumen. The mass was successfully resected by endoscopic-guided electrocautery ablation. Findings of histologic evaluation were consistent with a diagnosis of liposarcoma. Immediately following the ablation procedure, the previously noted clinical signs of respiratory tract disease resolved. On follow-up examination 12 months later, no regrowth of the mass was evident on thoracic helical CT and tracheoscopy. CLINICAL RELEVANCE Endoscopic-guided electrocautery ablation of tracheal liposarcoma was a safe and effective minimally invasive treatment for the dog of this report. The procedure was brief and appeared to be well tolerated, resulting in immediate improvement of clinical signs. PMID- 29461159 TI - Evaluation of tramadol for treatment of osteoarthritis in geriatric cats. AB - OBJECTIVE To evaluate tramadol for treatment of signs of pain and impaired mobility in geriatric cats with osteoarthritis. DESIGN Randomized controlled crossover trial. ANIMALS 24 client-owned geriatric (>= 10 years old) cats with osteoarthritis. PROCEDURES Otherwise healthy cats with owner-identified mobility impairment and clinical and radiographic evidence of osteoarthritis involving at least 1 appendicular joint were enrolled in the study. Cats were treated with tramadol orally at dosages of 0 (placebo), 1, 2, and 4 mg/kg (0, 0.45, 0.9, and 1.8 mg/lb) twice a day for 5 days, with a 2-day (weekend) washout period between treatments. Mobility was assessed with a collar-mounted activity monitor system, and impairments in activity were assessed with a client-completed questionnaire. RESULTS 17 cats completed the study; 7 cats were withdrawn. There was a significant increase in activity with the 2-mg/kg dosage of tramadol, compared with activity when cats received the placebo. Significantly more owners (11/18) considered their cats to have improved with the 2-mg/kg treatment, compared with all other dosages (6/19 to 8/21). Most owners (17/20 [85%]) considered their cat's global quality of life to have improved during the study. Adverse events, predominantly euphoria, dysphoria, sedation, decreased appetite, and diarrhea, were significantly more frequent with the 4-mg/kg (8/19) and 2-mg/kg (6/18) treatments but not with the 1-mg/kg (2/21) treatment, compared with frequency of adverse events with the placebo (0/21). CONCLUSIONS AND CLINICAL RELEVANCE Results suggested a beneficial effect of twice-daily oral administration of tramadol at a dosage of 2 mg/kg in geriatric cats with osteoarthritis. Adverse events were dose dependent, and caution should be exercised in cats that have concurrent disease or are receiving other drugs that may produce adverse gastrointestinal effects.

AB - OBJECTIVE To assess the prevalence of medical errors (specifically, near misses [NMs] and adverse events [AEs]) and their personal and professional impact on veterinarians. DESIGN Cross-sectional study. SAMPLE Members of the Veterinary Information Network (n = 46,481). PROCEDURES An electronic survey regarding veterinarians' experiences with NMs and AEs was distributed via email to an online veterinary community between September 24 and October 21, 2015. Responses were summarized and compared between genders by means of the chi2 test. RESULTS 606 veterinarians completed the survey (1.3% response rate). Overall, 447 (73.8%) respondents reported involvement in >= 1 NM (n = 389 [64.2%]) or AE (179 [29.5%]). The NMs had a short-term (<= 1 week) adverse impact on professional life for 68.0% (261/384) of respondents and longer-term negative impact for 36.4% (140/385). The impact on respondents' personal lives was similar (63.6% [245/385] and 33.5% [129/385], respectively). For AEs, these numbers were 84.1% (148/176), 56.2% (99/177), 77.8% (137/176), and 50.6% (89/175), respectively. Both NMs and AEs were more likely to negatively impact female veterinarians than male veterinarians. CONCLUSIONS AND CLINICAL RELEVANCE These findings suggested that many veterinarians experience emotional distress after a medical error. Support should be provided to mitigate this adverse impact on the wellbeing of veterinarians and, potentially, their future patients. PMID- 29461162 TI - An online survey of small animal veterinarians regarding current fluid therapy practices in dogs and cats. AB - OBJECTIVE To determine common fluid therapy practices of small animal practitioners and identify fluid therapy-related knowledge gaps that may benefit from improved educational efforts, targeted research, or both. DESIGN Online survey. SAMPLE 1,496 small animal veterinarians PROCEDURES An online survey was provided to members of the Veterinary Information Network between December 23, 2013, and January 30, 2014. The survey consisted of 24 questions investigating the administration of crystalloid and synthetic colloid solutions, but not blood products, and focused primarily on the choice of fluid type, frequency of administration, type of patient treated with fluids, treatment with fluids subcutaneously versus IV, and potassium supplementation of fluids. Only responses from practicing small animal veterinarians were included. Not all respondents answered every question, and some questions allowed > 1 answer. RESULTS Balanced crystalloid solutions were the most common fluid type in all clinical scenarios described. The most common maintenance IV fluid rate reported by respondents (762/1,333 [57%]) was 60 mL/kg/d (27 mL/lb/d); calculation of fluid administration rate by means of body surface area was infrequent. Challenges of fluid therapy included determining the appropriate rate (572/1,496 [38%]) and fluid type (497/1,496 [33%]) and determining the need for potassium supplementation (229/1,496 [15%]). CONCLUSIONS AND CLINICAL RELEVANCE Small animal veterinarians tended to favor isotonic balanced crystalloid solutions for IV fluid therapy, compared with other common choices such as isotonic saline (0.9% NaCl) solution. Despite its ubiquity, respondents found many aspects of fluid therapy to be challenging, suggesting the need for easy to use, evidence based guidelines. PMID- 29461163 TI - Pathology in Practice.

AB - OBJECTIVE To describe the radiographic outcome of root canal treatment (RCT) of canine teeth of cats. DESIGN Retrospective case series. ANIMALS 32 cats with 37 canine teeth with complicated crown fractures that underwent RCT. PROCEDURES Medical record databases of 5 referral veterinary hospitals were searched to identify cats that underwent RCT between 1998 and 2016. Only cats that had at least 1 follow-up examination during which radiographs were obtained of the treated canine tooth or teeth were included in the study. Dental radiographs obtained before and immediately after RCT and during all follow-up examinations were reviewed. Treatment was considered successful if the periodontal ligament space was within reference limits and preoperative external inflammatory root resorption (EIRR), if present, had stabilized. Treatment was considered to have no evidence of failure if preoperative EIRR had stabilized and preexisting periapical lucency was stable or decreased in size but had not resolved. Treatment was considered to have failed if periapical lucency or EIRR developed subsequent to RCT or preexisting periapical lucency increased in size or preoperative EIRR progressed following RCT. RESULTS Follow-up time after RCT ranged from 3 to 72 months. The RCT was successful for 18 (49%) of the 37 treated teeth, had no evidence of failure for 12 (32%), and failed for 7 (19%). Preexisting EIRR and patient age >= 5 years significantly increased the rate of RCT failure. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that RCT was a viable treatment option to salvage endodontically diseased canine teeth in cats. PMID- 29461168 TI - Letters to the Editor. PMID- 29461167 TI - Incidence of hospital-acquired anemia in hospitalized dogs and cats. AB - OBJECTIVE To determine the incidence of hospital-acquired anemia among dogs and cats hospitalized at a private emergency and referral center and identify possible risk factors. DESIGN Prospective, observational study. ANIMALS 56 patients (46 dogs and 10 cats). PROCEDURES Patients admitted from August 2014 through March 2015 and hospitalized for >= 48 hours were eligible for inclusion. Hospital-acquired anemia was defined as a PCV within reference limits on admission with development of anemia during hospitalization. Packed cell volume was measured once every 24 hours, and IV fluid volumes and blood volumes removed by means of phlebotomy were recorded. RESULTS The incidence of hospital-acquired anemia for dogs and cats combined was 34% (19/56) by 24 hours, 43% (24/56) by 48 hours, and 48% (27/56) by 72 hours. The incidence of hospital-acquired anemia was 70% (7/10) in cats and 43% (20/46) in dogs. Patients that underwent surgery had an increased odds of developing hospital-acquired anemia, compared with patients that did not undergo surgery (OR, 9.79; 95% confidence interval, 1.92 to 50.0). Cumulative phlebotomy volumes > 3% of total estimated blood volume significantly increased the risk of developing hospital-acquired anemia. CONCLUSIONS AND CLINICAL RELEVANCE Cumulative phlebotomy volumes > 3% of total blood volume and undergoing surgery significantly increased the risk that dogs and cats would develop hospital-acquired anemia. Further investigation is warranted for early identification of small animal patients at risk for development of hospital acquired anemia and to inform effective treatment strategies. PMID- 29461169 TI - Environmental stewardship practices of veterinary professionals and educators related to use and disposal of pharmaceuticals and personal care products. AB - OBJECTIVE To document the environmental stewardship practices (decisions and actions regarding use and disposal) of pet and human pharmaceuticals and personal care products (PPCPs) among pet-owning veterinary-care professionals (practicing veterinarians, veterinary students, and veterinary technicians and trainees) and environmental educators. DESIGN Internet-based cross-sectional survey. SAMPLE 191 pet owners (103 veterinary-care professionals and 88 environmental educators). PROCEDURES Study participants were recruited by means of a 2-part internet survey distributed to veterinary-care professional and environmental educator networks of individuals residing in Washington state, Oregon, and southern California. Survey questions addressed motivators for environmental stewardship practices (ie, decisions and actions regarding use and disposal of pet and human PPCPs). RESULTS Data were collected from 191 respondents; the response rate for individuals who self-selected to opt in was 78% (191/246). Of the 191 respondents, 42 (22%) stored pet pharmaceuticals indefinitely. The most common disposal method was the garbage (88/191 [46%]). Veterinary-care professionals counseled clients infrequently regarding environmental stewardship practices for PPCPs. Fifty-five percent (105/191) of all respondents preferred more environmentally friendly and clinically effective PPCPs. CONCLUSIONS AND CLINICAL RELEVANCE Results of the present survey emphasized the urgent need for improved educational resources to minimize environmental contamination from improper disposal of PPCPs. Environmental and economic motivations among pet owners in the veterinary-care and education professions indicate further opportunities for outreach and institutional support.

AB - Blinding retinal diseases become more epidemic as the population ages. These diseases, such as diabetic retinopathy and macular edema, are of chronic nature and require protracted drug presence at the disease site. A sustained intravitreal porous silicon delivery system with dexamethasone (pSiO2-COO-DEX) was evaluated in a new rabbit model of proliferative vitreoretinopathy (PVR) in a real treatment design. In contrast to the pretreatment design model, pSiO2-COO DEX was intravitreally injected into the eyes with active inflammation. Subretinal injection of vascular endothelial growth factor (VEGF) and Matrigel induced a late-onset vitreoretinal inflammation that gradually developed into PVR. This method mimics the human disease better than PVR induced by either intravitreal cell injection or trauma. The pSiO2-COO-DEX intervened eyes had minimal PVR, while balanced saline solution or free dexamethasone intervened eyes had significantly more PVR formation. In addition, adding VEGF to the Matrigel for subretinal injection induced greater inflammation and retinal neovascularization in comparison to only Matrigel injected under the medullary ray. Clinical and pathological examinations, including fundus fluorescein angiography and optical coherence tomography, confirmed these changes. In the current study, neither subretinal injection of Matrigel or subretinal injection of VEGF and Matrigel induced choroidal neovascularization. However, the current PVR model demonstrates a chronic course with moderate severity, which may be useful for drug screening studies. PMID- 29461174 TI - Faces, people and the brain: The 45th Sir Frederic Bartlett Lecture. AB - The fact that the face is a source of diverse social signals allows us to use face and person perception as a model system for asking important psychological questions about how our brains are organised. A key issue concerns whether we rely primarily on some form of generic representation of the common physical source of these social signals (the face) to interpret them, or instead create multiple representations by assigning different aspects of the task to different specialist components. Variants of the specialist components hypothesis have formed the dominant theoretical perspective on face perception for more than three decades, but despite this dominance of formally and informally expressed theories, the underlying principles and extent of any division of labour remain uncertain. Here, I discuss three important sources of constraint: first, the evolved structure of the brain; second, the need to optimise responses to different everyday tasks; and third, the statistical structure of faces in the perceiver's environment. I show how these constraints interact to determine the underlying functional organisation of face and person perception. PMID- 29461172 TI - Radiomics Based on Adapted Diffusion Kurtosis Imaging Helps to Clarify Most Mammographic Findings Suspicious for Cancer. AB - Purpose To evaluate a radiomics model of Breast Imaging Reporting and Data System (BI-RADS) 4 and 5 breast lesions extracted from breast-tissue-optimized kurtosis magnetic resonance (MR) imaging for lesion characterization by using a sensitivity threshold similar to that of biopsy. Materials and Methods This institutional study included 222 women at two independent study sites (site 1: training set of 95 patients; mean age +/- standard deviation, 58.6 years +/- 6.6; 61 malignant and 34 benign lesions; site 2: independent test set of 127 patients; mean age, 58.2 years +/- 6.8; 61 malignant and 66 benign lesions). All women presented with a finding suspicious for cancer at x-ray mammography (BI-RADS 4 or 5) and an indication for biopsy. Before biopsy, diffusion-weighted MR imaging (b values, 0-1500 sec/mm2) was performed by using 1.5-T imagers from different MR imaging vendors. Lesions were segmented and voxel-based kurtosis fitting adapted to account for fat signal contamination was performed. A radiomics feature model was developed by using a random forest regressor. The fixed model was tested on an independent test set. Conventional interpretations of MR imaging were also assessed for comparison. Results The radiomics feature model reduced false positive results from 66 to 20 (specificity 70.0% [46 of 66]) at the predefined sensitivity of greater than 98.0% [60 of 61] in the independent test set, with BI RADS 4a and 4b lesions benefiting from the analysis (specificity 74.0%, [37 of 50]; 60.0% [nine of 15]) and BI-RADS 5 lesions showing no added benefit. The model significantly improved specificity compared with the median apparent diffusion coefficient (P < .001) and apparent kurtosis coefficient (P = .02) alone. Conventional reading of dynamic contrast material-enhanced MR imaging provided sensitivity of 91.8% (56 of 61) and a specificity of 74.2% (49 of 66). Accounting for fat signal intensity during fitting significantly improved the area under the curve of the model (P = .001). Conclusion A radiomics model based on kurtosis diffusion-weighted imaging performed by using MR imaging machines from different vendors allowed for reliable differentiation between malignant and benign breast lesions in both a training and an independent test data set.

PMID- 29461178 TI - Correlates and Predictors of New Mothers' Responses to Postpartum Thoughts of Accidental and Intentional Harm and Obsessive Compulsive Symptoms. AB - BACKGROUND: Unwanted, intrusive thoughts of infant-related harm are a normal, albeit distressing experience for most new mothers. The occurrence of these thoughts can represent a risk factor for the development of obsessive compulsive disorder (OCD). As the early postpartum period represents a time of increased risk for OCD development, the transition to parenthood provides a unique opportunity to better understand OCD development. AIMS: The purpose of this study was to assess components of cognitive behavioural conceptualizations of postpartum OCD in relation to new mothers' thoughts of infant-related harm. METHOD: English-speaking pregnant women (n = 100) participated. Questionnaires were completed at approximately 36 weeks of gestation, and at 4 and 12 weeks postpartum. An interview to assess postpartum harm thoughts was administered at 4 and 12 weeks postpartum. Questionnaires assessed OC symptoms, OC-related beliefs, fatigue, sleep difficulties and negative mood. RESULTS: Prenatal OC-related beliefs predicted postpartum OC symptoms, as well as harm thought characteristics and behavioural responses to harm thoughts. The severity of behavioural responses to early postpartum harm thoughts did not predict later postpartum OC symptoms, but did predict frequency and time occupation of accidental harm thoughts, and interference in parenting by intentional harm thoughts. Strong relationships between OC symptoms and harm thought characteristics, and concurrent sleep difficulties, negative mood and fatigue were also found. CONCLUSIONS: Findings provide support for cognitive behavioural conceptualizations of postpartum OCD and emphasize the importance of maternal sleep, fatigue and negative mood in the relationship between OC-related beliefs and maternal cognitive and behavioural responses to postpartum harm thoughts. PMID- 29461179 TI - Oleiharenicola alkalitolerans gen. nov., sp. nov., a new member of the phylum Verrucomicrobia isolated from an oilsands tailings pond. AB - A novel member of the phylum Verrucomicrobia was isolated from an oilsands tailings pond in Alberta, Canada. Cells of isolate NVTT are Gram-negative, strictly aerobic, non-pigmented, non-motile cocci to diplococci 0.5-1.0 um in diameter. The bacterium is neutrophilic (optimum pH 6.0-8.0) but alkalitolerant, capable of growth between pH 5.5 and 11.0. The temperature range for growth is 15 40 degrees C (optimum 25-37 degrees C). Carbon and energy sources include sugars and organic acids. Nitrogen sources include nitrate, urea, l-glycine, l alanine, l-proline and l-serine. Does not fix atmospheric nitrogen. Does not require NaCl and is inhibited at NaCl concentrations above 3.0 % (w/v). The DNA G+C content of strain NVTT, based on a draft genome sequence, is 66.1 mol%. MK-6 and MK-7 are the major respiratory quinones. Major cellular fatty acids are anteiso-C15 : 0 and iso-C15 : 0. Phylogenetic analysis of 16S rRNA gene sequences revealed that the strain belongs to the family Opitutaceae of the phylum Verrucomicrobia. The most closely related validated species is Opitutus terrae (93.7 % 16S rRNA gene sequence identity to its type strain PB90-1T). Based on genotypic, phenotypic and chemotaxonomic characteristics, it was concluded that this strain represents a novel genus and species, for which the name Oleiharenicola alkalitolerans gen. nov., sp. nov. is proposed. The type strain of this novel species is NVTT (=ATCC BAA-2697T;=DSM 29249T). PMID- 29461180 TI - Pedobacter mongoliensis sp. nov., isolated from grassland soil. AB - A Gram-stain-negative, rod-shaped, motile by gliding and strictly aerobic bacterial strain, named 1-32T, was isolated from soil of the Ordos grassland in Inner Mongolia, PR China. Strain 1-32T showed highest 16S rRNA gene sequence similarities to Pedobacter luteus N7d-4T (95.4 %), Pedobacter oryzae DSM 19973T (95.3 %), 'Pedobacter xinjiangensis' 12157T (95.2 %) and Pedobacter tournemirensis TF5-37.2-LB10T (95.1 %). Phylogenetic analyses clustered strain 1 32T with 'P. xinjiangensis' 12157T and P. tournemirensis TF5-37.2-LB10T. The DNA G+C content was 43.4 mol%. Menaquinone 7 was the main respiratory quinone. The predominant fatty acids (>5 %) were iso-C15 : 0, summed feature 3 (C16 : 1omega6c and/or C16 : 1omega7c), iso-C17 : 0 3-OH, iso-C15 : 0 3-OH and C16 : 1omega5c. The polar lipids of strain 1-32T comprised phosphatidylethanolamine, two unidentified polar lipids, one unidentified glycolipid and two unidentified phospholipids. Strain 1-32T could be distinguished from the other members of the genus Pedobacter based on its phylogenetic distance and physiological and biochemical characteristics such as being negative for the assimilation of rhamnose and the activity of alpha-glucosidase. Therefore, strain 1-32T represents a novel species of the genus Pedobacter, for which the name Pedobacter mongoliensis sp. nov. is proposed. The type strain is 1-32T (=KCTC 52859T=CCTCC AB 2017084T).

AB - A Gram-stain-negative, facultatively aerobic, aromatic hydrocarbon-degrading bacterium, designated strain BN5T, was isolated from gasoline-contaminated soil. Cells were motile and slightly curved rods with a single flagellum showing catalase and oxidase activities. Growth was observed at 20-37 degrees C (optimum, 25-30 degrees C), pH 3-7 (optimum, pH 5-6) and 0-2 % NaCl (optimum, 0 %). Ubiquinone-8 was the predominant respiratory quinone. The major fatty acids were C16 : 0, cyclo-C19 : 0omega8c and summed feature 8 (comprising C18 : 1omega7c and/or C18 : 1omega6c). Diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, an unidentified phosphoamino lipid, three unidentified amino lipids and eight unidentified lipids were the identified polar lipids. The DNA G+C content was 62.93 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain BN5T formed a phylogenic lineage with members of the genus Paraburkholderia and showed the highest 16S rRNA gene sequence similarities to Paraburkholderia phytofirmans PsJNT (99.4 %), Paraburkholderia dipogonis DL7T (98.8 %) and Paraburkholderia insulsa PNG-AprilT (98.8 %). The average nucleotide identity and in silico DNA-DNA hybridization (DDH) values between strain BN5T and P. phytofirmans PsJNT were 88.5 and 36.5 %, respectively. The DDH values for strain BN5T with P. dipogonis LMG 28415T and P. insulsa DSM 28142T were 41.0+/-4.9 % (reciprocal, 33.0+/-4.3 %) and 47.1+/-6.6 % (reciprocal, 51.7+/-5.4 %), respectively. Based on its physiological, chemotaxonomic and phylogenetic features, we conclude that strain BN5T is a novel species of the genus Paraburkholderia, for which the name Paraburkholderia aromaticivorans sp. nov. is proposed. The type strain is BN5T (=KACC 19419T=JCM 32303T). PMID- 29461182 TI - Molecular characterization and antifungal susceptibility testing of Cryptococcus neoformans sensu stricto from southern Brazil. AB - PURPOSE: Cryptococcosis is acquired from the environment by the inhalation of Cryptococcus cells and may establish from an asymptomatic latent infection into pneumonia or meningoencephalitis. The genetic diversity of a Cryptococcus neoformans species complex has been investigated by several molecular tools, such as multi-locus sequence typing, amplified fragment length polymorphism (AFLP), restriction fragment length polymorphism and microsatellite analysis. This study aimed to investigate the genotype distributions and antifungal susceptibility profiles of C. neoformans sensu lato isolates from southern Brazil. METHODOLOGY: We studied 219 C. neoformans sensu lato isolates with mating- and serotyping, AFLP fingerprinting, microsatellite typing and antifungal susceptibility testing.Results/Key findings. Among the isolates, 136 (69 %) were from HIV positive patients. Only C. neoformans mating-type alpha and serotype A were observed. AFLP fingerprinting analysis divided the isolates into AFLP1/VNI (n=172; 78.5 %), AFLP1A/VNII (n=19; 8.7 %), AFLP1B/VNII (n=4; 1.8 %) and a new AFLP pattern AFLP1C (n=23; 10.5 %). All isolates were susceptible to tested antifungals and no correlation between antifungal susceptibility and genotypes was observed. Through microsatellite analysis, most isolates clustered in a major microsatellite complex and Simpson's diversity index of this population was D=0.9856. CONCLUSION: The majority of C. neoformans sensu stricto infections occurred in HIV-positive patients. C. neoformans AFLP1/VNI was the most frequent genotype and all antifungal drugs had high in vitro activity against this species. Microsatellite analyses showed a high genetic diversity within the regional C. neoformans sensu stricto population, and correlation between environmental and clinical isolates, as well as a temporal and geographic relationship. PMID- 29461183 TI - Roseovarius nitratireducens sp. nov., a halotolerant bacterium isolated from a saline lake. AB - A Gram-stain-negative, aerobic, non-motile and ovoid- to rod-shaped bacterial strain, designated TFZT, was isolated from a water sample of a saline lake in Xinjiang, China and subjected to polyphasic taxonomic investigation. Strain TFZT grew at 4-42 degrees C and pH 6.5-10.0 (optimum, 30 degrees C and pH 7.0) and with 0.5-18.0 % (w/v) NaCl (optimum, 1.5 %). According to phylogenetic analysis based on 16S rRNA gene sequences, strain TFZT was assigned to the genus Roseovarius with highest 16S rRNA gene sequence similarity of 97.5 % to Roseovarius tolerans EL-172T, followed by Roseovarius azorensis SSW084T (96.6 %) and Roseovarius mucosus DSM 17069T (95.5 %). Digital DNA-DNA hybridization (DDH) and average nucleotide identity (ANI) were determined to evaluate the genomic relationship between strain TFZT and R. tolerans EL-172T. Digital DDH estimation (22.80+/-2.35 %) as well as ANI (80.1 %) proved the dissimilarity of strain TFZT. Chemotaxonomic analysis showed that strain TFZT contained ubiquinone-10 as the predominant respiratory quinone and possessed summed feature 8 (comprising C18 : 1omega7c and/or omega6c) and C16 : 0 as the predominant form of fatty acid. The polar lipids of strain TFZT consisted of phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine and five unidentified lipids. The DNA G+C content was 65.4 mol% (by genome sequencing). Based on the polyphasic taxonomic characterization, strain TFZT is considered to represent a novel species of the genus Roseovarius, for which the name Roseovariusnitratireducens sp. nov. is proposed (type strain TFZT=MCCC 1K03339T=KCTC 52967T). PMID- 29461184 TI - Cryobacterium aureum sp. nov., a psychrophilic bacterium isolated from glacier ice collected from the ice tongue surface. AB - A psychrophilic, Gram-stain-positive, rod-shaped bacterium, designated strain Hh31T, was isolated from Xinjiang No. 1 Glacier in China. Strain Hh31T was catalase-positive, oxidase-negative and able to grow at between 0-18 degrees C. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain Hh31T belonged to the genus Cryobacterium and was most closely related to the type strains of Cryobacterium levicorallinum, Cryobacterium luteum and Cryobacterium flavum. DNA-DNA hybridization, calculation of average nucleotide identity and digital DNA-DNA hybridization revealed that strain Hh31T was distinct from its closest phylogenetic neighbours. The major cellular fatty acids of strain Hh31T were anteiso-C15 : 0, anteiso-C15 : 1, iso-C15:0, iso-C16 : 0 and anteiso-C17 : 0. The predominant menaquinones of strain Hh31T were MK-9 and MK-10. The polar lipids consisted of diphosphatidylglycerol, phosphatidylglycerol, one unidentified phospholipid, one unidentified glycolipid and another unidentified lipid. Physiological tests such as carbon source utilization, showed phenotypic differentiation of strain Hh31T from the closest related phylogenetic neighbours. Based on a polyphasic approach, a novel species, Cryobacterium aureum sp. nov., is proposed, with Hh31T (=NBRC 107882T=CGMCC 1.11213T) as the type strain. PMID- 29461185 TI - 1,4-Naphthoquinone derivatives potently suppress Candida albicans growth, inhibit formation of hyphae and show no toxicity toward zebrafish embryos. AB - PURPOSE: In this study, we applied various assays to find new activities of 1,4 naphthoquinone derivatives for potential anti-Candida albicans applications. METHODOLOGY: These assays determined (a) the antimicrobial effect on growth/cell multiplication in fungal cultures, (b) the effect on formation of hyphae and biofilm, (c) the influence on cell membrane integrity, (d) the effect on cell morphology using atomic force microscopy, and (e) toxicity against zebrafish embryos. We have demonstrated the activity of these compounds against different Candida species and clinical isolates of C. albicans. KEY FINDINGS: 1,4 Naphthoquinones significantly affected fungal strains at 8-250 mg l-1 of MIC. Interestingly, at concentrations below MICs, the chemicals showed effectiveness in inhibition of hyphal formation and cell aggregation in Candida. Of note, atomic force microscopy (AFM) analysis revealed an influence of the compounds on cell morphological properties. However, at low concentrations (0.8-31.2 mg l-1), it did not exert any evident toxic effects on zebrafish embryos. CONCLUSIONS: Our research has evidenced the effectiveness of 1,4-naphthoquinones as potential anti Candida agents. PMID- 29461186 TI - Saturnispora kantuleensis f.a., sp. nov., a novel yeast species isolated from peat in a tropical peat swamp forest in Thailand. AB - Two strains (DMKU-PPS4-5T and DMKU-EPS3-4) representing a single novel anamorphic yeast species were isolated from two peat samples collected in Kan Tulee peat swamp forest, Surat Thani Province, Thailand. The strains differed by two nucleotide substitutions in the sequences of the D1/D2 region of the large subunit (LSU) rRNA gene and only one nucleotide substitution in the internal transcribed spacer (ITS) region. Phylogenetic analysis based on the D1/D2 regions showed that the two strains represented a single species in the genus Saturnispora and were clearly distinct from other related species. Saturnispora sekii was the most closely related species, but with 1.7-2.1 % nucleotide substitutions in the D1/D2 region of the LSU rRNA gene, and 3.1-3.3 % nucleotide substitutions in the ITS region. They therefore represent a novel species of the genus Saturnispora, although the formation of ascospores was not observed. The name Saturnispora kantuleensis f.a., sp. nov. is proposed. The type strain is DMKU-PPS4-5T (=CBS 15217T=TBRC 7762T). PMID- 29461187 TI - Detection of Coxiella burnetii in heart valve sections by fluorescence in situ hybridization. AB - PURPOSE: Infective endocarditis is a severe and potentially fatal disease. Nearly a third of all cases remain culture-negative, making a targeted and effective antibiotic therapy of patients challenging. In the past years, fluorescence in situ hybridization (FISH) has proven its value for the diagnosis of infective endocarditis, particularly when it is caused by fastidious bacteria. To increase the number of infective endocarditis causing agents, which can be identified by FISH, we designed and optimized a FISH-probe for the specific detection of Coxiella burnetii in heart valve tissue. METHODOLOGY: Even with specific probes the detection and identification of bacteria can be complicated by the high autofluorescence due to calcification of the analysed tissue. To overcome this problem, we developed a protocol to detect C. burnetii by hybridizing, stripping and reprobing the identical section with different species-specific probes repeatedly.Results/Key findings. The newly designed specific FISH probe and the developed protocol exemplarily allowed us to unequivocally identify C. burnetii in tissue sections of a patient with infective endocarditis. CONCLUSION: This method provides an add-on to existing protocols for the unambiguous diagnosis of bacteria directly within tissues or other difficult tissue samples in cases with small sample size and limited sections.

AB - Patients commonly present with shoulder complaints to the primary care and orthopaedic setting. The differential includes rotator cuff tears, subacromial impingement, osteoarthritis, and adhesive capsulitis, also known as frozen shoulder. Despite the prevalence of adhesive capsulitis, it is commonly misdiagnosed and management remains unclear. This article reviews the presentation of adhesive capsulitis, presents an overview of the pathophysiology of this poorly understood disease, and evaluates nonoperative treatment options for adhesive capsulitis.

AB - The study evaluated the physical,mental, and functional outcomes following below the-knee amputation (BKA) for management of chronic, debilitating lower extremity pain. The hypothesis was that patients who undergo a BKA to alleviate chronic pain achieve a greater level of function, experience decreased pain, and benefit from improved health-related quality of life. Patients who received a BKA attended an orthopaedic clinic and completed questionnaires examining their overall health, functional status, mental health, and pain. Thirty-seven patients were identified as eligible for study participation; 15 agreed to participate. Although most participants continued to experience pain in their residual limb after BKA, they reported their pain decreased to a manageable level. Participants experienced a statistically significant improvement in their perceived physical health. The authors believe a BKA for chronic pain is a reasonable treatment option for patients who continue to experience lower extremity pain after failed medical and surgical management of chronic pain.

AB - Lower extremity nervous anatomy is highly variable. This study sought to determine relationships of lower extremity peripheral nerves to anatomic landmarks. Sixteen well-preserved lower extremities were dissected. The distance from each nerve point of interest to relevant landmarks was measured in standardized fashion. The sciatic nerve divided on average 26.0% +/- 5% of the distance from the superior aspect of the fibula to the greater trochanter proximal to the knee joint line [Pearson correlation coefficient (PCC) D 0.764]. The superficial peroneal nerve pierced the crural fascia at an average of 28.0% +/- 6% of the fibular length proximal to the lateral malleolus (PCC D 0.718). The deep peroneal nerve emerged between the tibialis anterior and extensor hallucis longus on average 2.7% +/- 0.4% of the fibular length proximal to the tibiotalar joint line (PCC D 0.530). While there was substantial variability in the course of lower extremity peripheral nerves, the study found strong correlation with femur and fibula length within each specimen.

PMID- 29461192 TI - Return of Quadriceps Strength After Primary Total Knee Arthroplasty With Single Radius Knee System: Five-Year Follow-up. AB - Preoperative quadriceps muscle strength (isometric peak torque) was expectedly lower on the total knee arthroplasty side in comparison with the unaffected contralateral side and it was further reduced after surgery. This reduction continued for up to 6 months postoperatively. After 6 months, muscle strengths exceeded preoperative values and continued to increase for the following 2 years. From 2 to 5 years postoperatively, there was a tendency for decline; however, the quadriceps muscle strength still exceeded preoperative values. On the nonoperative side, the increase in muscle strength was detected 1 year after surgery and it was still noticeable at 5 years. Contralateral side improvement can be explained by the increased mobility of the patients. Knee Society Scores and function scores were significantly increased at 3 months after surgery and were significantly greater than preoperative values 5 years after surgery. SF-12 (physical score) exceeded preoperative values at 3 months and this increase was observed continuously over the 5-year follow-up. (Journal of Surgical Orthopaedic Advances 26(4):211-215, 2017). PMID- 29461193 TI - Blood Transfusion After Primary Total Hip Arthroplasty: National Trends and Perioperative Outcomes. AB - The purpose of this study was to quantify the changes in transfusion rates, both allogeneic blood transfusion (ALBT) and autogenic blood transfusion (ATBT) on a national scale, and determine patient factors associated with transfusions. The National Hospital Discharge Survey was evaluated between 2001 and 2010 for primary total hip arthroplasty (THA) patients and categorized on the basis of transfusion necessity, type, and comorbidity burden. A logistic regression comparison of ALBT, ATBT, and nontransfused patients was performed with respect to patient demographics and in-hospital complications. The proportion of patients requiring any transfusion decreased from an average rate of 22.8% between 2001 and 2005 to 21.2% between 2006 and 2010 (p = .01). ATBT rates decreased (r = .99) from 11.0% in 2001 to 2.8% in 2010. ALBT rates increased (r = .66) from 14% in 2001 to 16.6% in 2010. The number of patients requiring a blood transfusion after THA decreased in the United States with a trend shifting from ATBT to ALBT. (Journal of Surgical Orthopaedic Advances 26(4):216-222, 2017). PMID- 29461194 TI - Smartphone-Based Goniometry Accuracy in Clinical Scenarios. AB - This study compared two popular iPhone-based goniometer applications to the gold standard universal goniometer for the measurement of the hip and knee joints in scenarios mimicking the normal pace of an orthopaedic clinical practice.Three physicians measured hip and knee joint angles 35 times with one of three goniometers: universal 12-inch goniometer, DrGoniometer (iPhone-5 based), and SimpleGoniometer (iPhone-5 based). Data wwere analyzed using Pearson correlation coefficient calculations. Average knee angles measured with the universal goniometer, DrGoniometer, and SimpleGoniometer measured 83.46 degrees , 85.23 degrees , and 80.39 degrees , respectively. The smartphone-based goniometers had moderate agreement with the universal goniometer in the knee (r > .322). Average hip angles measured with the universal goniometer, DrGoniometer, and SimpleGoniometer measured 62.34 degrees , 60.87 degrees , and 59.34 degrees , respectively. The smartphone-based goniometers had moderate agreement with the universal goniometer in the hip (r > .168). Smartphone-based goniometers gave accurate, with weak to moderate correlation, measurements for the knee and hip. (Journal of Surgical Orthopaedic Advances 26(4):223-226, 2017). PMID- 29461195 TI - Predictors of Carpal Tunnel Release After Open Distal Radius Fracture. AB - The purpose of this investigation was to determine the incidence and identify the predictors of carpal tunnel release (CTR) after open fractures of the distal radius (DRF). Patients with clinical symptoms of persistent median nerve neuropathy that required CTR were analyzed for risk factors. One hundred thirty nine open DRFs (107 grade I, 23 grade II, 9 grade III) met the inclusion criteria. The incidence of CTR was 13.7% in all open DRFs (19 out of 139). Multivariable logistic regression analysis identified four predictors: male sex [odds ratio (OR) = 8.8, p = .001], type III Gustilo and Anderson grade (OR = 6.2, p = .04), OTA fracture type C (OR = 3.8, p = .03), and the application of external fixation (OR = 14.0, p D .02). The probability of CTR, determined by preoperative variables, was 80% with three factors present and 2% with no risk factors. High-risk patients may be identified who may benefit from closer perioperative surveillance and possibly carpal tunnel release. (Journal of Surgical Orthopaedic Advances 26(4):227-232, 2017). PMID- 29461196 TI - Intramedullary Bone Graft Harvest Using Reamer-Irrigator-Aspirator System: A Case Series. AB - Autogenous iliac crest bone grating has been the gold standard. Recently, intramedullary bone graft harvest using a reamer-irrigator-aspirator (RIA) had been gaining more interest among orthopedic surgeons. Twenty-four RIA bone graft harvesting procedures in 23 consecutive patients with nonunions were included. The mean age was 37.8 years. Rates of perioperative complications, secondary surgical procedures, and union were assessed for all patients. At mean 10.1 months follow-up, three donor site complications occurred (12.5%), including two fractures (8.3%). Eighteen patients (78%) progressed to radiographic union, three (13%) were lost for follow-up, and two (9%) failed to achieve union. Mean reamer size was 13.7 mm (mode, 14.0 mm), producing an average volume of 39.4 mL (range, 15-90 mL) bone graft. While RIA bone grafting results in predictably high rates of union, patients should be counseled extensively about fracture risk. Tibial RIA may be less optimal as a primary source of bone grafting.

AB - Treating patients with antibiotics that are selected based on routine cultures obtained from presumed aseptic orthopaedic procedures may lead to an increased risk of antibiotic-related complications without reducing the rate of late deep infection. Routine cultures obtained from 60 of 169 procedures resulted in 23 (38.3%) positive and 37 (61.7%) negative results. Twenty-two patients (13.5%) developed late infections. Seven of 14 patients with positive cultures, who were treated with antibiotics, developed a late infection, while two of nine patients with routine cultures, who received no antibiotic treatment, developed a late infection. Six of 37 patients with negative cultures and seven of 109 patients with no cultures developed a late infection. In patients who developed late deep infection, the microorganism isolated on routine culture only corresponded to the microorganism causing late infection 55.5% of the time. Of all patients treated with antibiotics, seven (29%) experienced an antibiotic-related complication (p = .01). (Journal of Surgical Orthopaedic Advances 26(4):239-245, 2017). PMID- 29461198 TI - Radiation Exposure to the Orthopaedic Surgeon and Efficacy of a Novel Radiation Attenuation Product. AB - The purpose of this study was to examine the intraoperative radiation dosage to different body parts and to determine the effectiveness of a new lightweight radiation-attenuating fabric (XPF) versus lead, the current standard. For 51 cases involving fluoroscopy, one attending orthopaedic surgeon wore a set of three dosimeters at various locations. Per each set of three, one dosimeter was shielded with a swatch of XPF, one was placed underneath the lead apron, and one was left exposed. The total dose of radiation was tabulated per body site and the percent attenuation was calculated for both XPF and lead. There was no statistically significant difference in the percent of radiation attenuation by lead and XPF (p = .47). The use of XPF produced 57.83% reduction in weight compared with lead when adjusting for total surface body area. XPF can be used for operating room personnel and patients, providing effective protection from radiation. (Journal of Surgical Orthopaedic Advances 26(4):246-249, 2017). PMID- 29461199 TI - Patient Satisfaction After Bilateral Thumb Carpometacarpal Osteoarthritis Surgery. AB - This study seeks to determine whether patients with bilateral thumb carpometacarpal osteoarthritis were sufficiently satisfied with their surgeries to choose to undergo surgery again. The null hypothesis is that patients are dissatisfied with the results of the first surgery. Out of 46 living patients meeting enrollment criteria, 41 were enrolled and evaluated using the Disabilities of the Arm, Shoulder and Hand (DASH) score and the Enneking musculoskeletal score. The average DASH score was 17.37. The average Enneking musculoskeletal score was 88.21. Of 41 patients, one expressed unwillingness to undergo the next procedure, three indicated that they would reluctantly do surgery again, and four were satisfied. The remaining 33 subjects were enthused with their functional result, expressing willingness to undergo the procedure again. At an average follow-up of 44.9 months, most patients are satisfied with bilateral thumb carpometacarpal surgery for osteoarthritis. Consent for the contralateral surgery implies that the outcome of the first surgery was sufficiently acceptable to seek surgery on the contralateral thumb.

PMID- 29461200 TI - Implementation of a Service-Specific Template Integrating Objective Structured Clinical Examination and Accreditation Council for Graduate Medical Education Milestones: One Institution's Experience. AB - The Accreditation Council for Graduate Medical Education (ACGME) orthopaedic milestones require detailed, frequent resident evaluations. This institution desired a cost-effective objective structured clinical examination (OSCE) to facilitate these evaluations. Data were collected as a prospective, uncontrolled observational study. The OSCE was completed by residents entering and exiting the foot and ankle rotation during postgraduate years 2 and 4. Physician assistants functioned as standardized patients. Statistical analyses were performed using paired and independent t tests. The OSCE was implemented using reliable, low-cost modalities and has facilitated milestones evaluations. Preliminary data show 4th year residents performed higher in prerotation global assessment with a standardized patient and written exam (p < .03). Second-year residents showed improvement in the written exam on rotation completion (p = .03). Using this methodology, institutions may establish similar cost-effective OSCEs as feasible evaluative solutions to satisfy milestone requirements. The authors believe this tool may be modified for any specialty. (Journal of Surgical Orthopaedic Advances 26(4):257-261, 2017). PMID- 29461201 TI - Return to Duty Following a Tibial Tubercle Osteotomy. AB - Anterior knee pain is a common complaint among military members, with a negative impact on operational readiness. A tibial tubercle osteotomy is one treatment option for select etiologies of anterior knee pain and has been reported to result in high rates of return to activity. A retrospective review of active duty service members undergoing a tibial tubercle osteotomy at a single army medical center was performed. Thirteen active duty service members were identified as undergoing a tibial tubercle osteotomy. Nine patients remained on active duty at 1 year following surgery. After 24 months, only four service members remained on active duty, while seven were medically retired. Seventy-five percent of patients who underwent concomitant cartilaginous procedure underwent a medical discharge. A small subset of active duty military personnel who underwent a tibial tubercle osteotomy was able to remain on active duty, but concomitant cartilaginous procedures did not appear to be compatible with retention on active duty because of the high physical demands placed on soldiers.

PMID- 29461203 TI - Circulating CD34+ hematopoietic stem/progenitor cells paralleled with level of viremia in patients chronically infected with hepatitis B virus. AB - INTRODUCTION: Liver regeneration is a heterogeneous process involving proliferation of different cell types in response to injury. Bone marrow derived stem cells may be involved in this process, by making contribution to parenchymal restoration and cellular replacement. We aimed to investigate the correlation between level of circulating mobilized CD34+ hematopoietic stem progenitor cells (HSPCs) and viremia level in patients chronically infected with hepatitis B virus (HBV). METHODS: Blood samples were prospectively collected for assessing percentage and absolute counts of circulating CD34+ HSPCs and viral load level using flow cytometry and RT-PCR respectively. Patients with chronic hepatitis B (CHB) (n = 30), Entecavir (ETV) treated subjects (n = 30) and 20 age and gender matched healthy controls were enrolled in this study. Results were expressed as mean +/- SD. RESULTS AND DISCUSSION: A significant increase in circulating CD34+ HSPCs level was observed in CHB patients (5 +/- 3.1, 324 +/- 195 * 103/ml) as compared to ETV treated subjects (0.57 +/- 0.27,1022 +/- 325) and healthy controls (0.53 +/- 0.37, 694 +/- 254, P < 0.001) in regards to percentage and absolute counts respectively. Levels of CD34+ HSPCs strongly and positively correlated with HBV DNA viral load levels in CHB patients (r2 = 0.8417, 0.649, P < 0.001).Thus, in chronic liver disorders (CHB), when reduced regenerative capacity of hepatocytes is reached, BMSCs mobilization occurs and their level increases in peripheral blood. The level of circulating CD34+ cells in peripheral blood of CHB patients paralleled with the hepatitis B viral load. PMID- 29461204 TI - SAC1 degrades its lipid substrate PtdIns4P in the endoplasmic reticulum to maintain a steep chemical gradient with donor membranes. AB - Gradients of PtdIns4P between organelle membranes and the endoplasmic reticulum (ER) are thought to drive counter-transport of other lipids via non-vesicular traffic. This novel pathway requires the SAC1 phosphatase to degrade PtdIns4P in a 'cis' configuration at the ER to maintain the gradient. However, SAC1 has also been proposed to act in 'trans' at membrane contact sites, which could oppose lipid traffic. It is therefore crucial to determine which mode SAC1 uses in living cells. We report that acute inhibition of SAC1 causes accumulation of PtdIns4P in the ER, that SAC1 does not enrich at membrane contact sites, and that SAC1 has little activity in 'trans', unless a linker is added between its ER anchored and catalytic domains. The data reveal an obligate 'cis' activity of SAC1, supporting its role in non-vesicular lipid traffic and implicating lipid traffic more broadly in inositol lipid homeostasis and function. PMID- 29461206 TI - Oral Immunotherapy With Egg and Milk: Changes in Peripheral Serum Cytokines Are Not Predictive Factors for Severe Adverse Reactions or for the Final Report. AB - BACKGROUND: Oral immunotherapy (OIT) is a new approach in patients with food allergy. Various immunological mechanisms underlie the reversal of food allergy. In this paper, we study possible changes in peripheral cytokine patterns during OIT. METHODS: Determinations of cytokines in peripheral blood were made in children who had milk or egg allergy and who received OIT. The determinations were made before and after OIT, and again following a final repeat oral challenge a month after a diet excluding the culprit food. RESULTS: No significant changes were registered in the cytokines studied (IL-2, IL-4, IL-6, IL-10, IL-12, IL-17, IFNgamma, and TNF) at any of the 3 time points. Similarly, no differences in cytokine pattern were observed between children who had presented anaphylaxis during OIT and those who overcame or did not overcome the final oral challenge. DISCUSSION: Peripheral cytokines do not undergo significant changes during the OIT process. They are not predictors of serious adverse reactions or the final result of the OIT.

AB - BACKGROUND AND OBJECTIVE: The increasing prevalence of food allergy affects both patients and their families. Objective: The aim of this study was to evaluate the impact of an online educational program designed for parents and caregivers of children with food allergies. The program was developed by a multidisciplinary group comprising health care professionals, researchers, and expert patients under the participatory medicine model. MATERIAL AND METHODS: Participants took a 2-week online educational program covering major topics in food allergy management. General knowledge about the disease, symptoms, treatment, and topics relevant to families' daily lives were evaluated. The contents included educational videos, online forums, and live video chats. A pretest/posttest questionnaire survey was used to evaluate the impact of the program. RESULTS: A total of 207 participants enrolled in the educational program, which was completed by 130 (62.8%). Knowledge acquisition improved significantly following participation in the program in 15 out of 30 items (50%), reaching P<.001 for 8 items (26.7%). Of the 207 participants who started the program, 139 (67.1%) visited online forums, and 27.5% attended video chats. Average overall satisfaction with the educational program was 8.78 (on a scale of 0 to 10). CONCLUSIONS: The results obtained show that parents improved their knowledge in all areas of food allergy. The high level of satisfaction among participants suggests that digital learning tools are effective and motivational, enabling patients to acquire appropriate knowledge and thus increasing their quality of life.

PMID- 29461205 TI - PTEN negatively regulates the cell lineage progression from NG2+ glial progenitor to oligodendrocyte via mTOR-independent signaling. AB - Oligodendrocytes (OLs), the myelin-forming CNS glia, are highly vulnerable to cellular stresses, and a severe myelin loss underlies numerous CNS disorders. Expedited OL regeneration may prevent further axonal damage and facilitate functional CNS repair. Although adult OL progenitors (OPCs) are the primary players for OL regeneration, targetable OPC-specific intracellular signaling mechanisms for facilitated OL regeneration remain elusive. Here, we report that OPC-targeted PTEN inactivation in the mouse, in contrast to OL-specific manipulations, markedly promotes OL differentiation and regeneration in the mature CNS. Unexpectedly, an additional deletion of mTOR did not reverse the enhanced OL development from PTEN-deficient OPCs. Instead, ablation of GSK3beta, another downstream signaling molecule that is negatively regulated by PTEN-Akt, enhanced OL development. Our results suggest that PTEN persistently suppresses OL development in an mTOR-independent manner, and at least in part, via controlling GSK3beta activity. OPC-targeted PTEN-GSK3beta inactivation may benefit facilitated OL regeneration and myelin repair.

AB - BACKGROUND: Limited research has evaluated risk factors for low bone mineral density (BMD) in male adolescent athletes. AIMS/OBJECTIVES: To evaluate predictors of low BMD (defined as BMD Z-score <-1.0) in a sample of male adolescent distance runner and non-runner athletes. METHODS: Male adolescent athletes completed a survey characterising sports participation, nutrition, stress fracture history, dual energy X-ray absorptiometry (DXA)-measured BMD and body composition. Independent t-tests and analysis of covariance (ANCOVA) evaluated group differences; logistic regression evaluated low BMD risk factors. RESULTS: Runners (n=51) exhibited a lower body weight (p=0.02), body mass index (BMI) (kg/m2) (p=0.02), per cent expected weight (p=0.02) and spine BMD Z-score (p=0.002) compared with non-runners (n=18). Single risk factors of low BMD included <85% expected weight (OR=5.6, 95% CI 1.4 to 22.5) and average weekly mileage >30 in the past year (OR=6.4, 95% CI 1.5 to 27.1). The strongest two variable and three-variable risk factors included weekly mileage >30+ stress fracture history (OR=17.3, 95% CI 1.6 to 185.6) and weekly mileage >30+<85% expected weight + stress fracture history (OR=17.3, 95% CI 1.6 to 185.6), respectively. Risk factors were cumulative when predicting low BMD (including <85% expected weight, weekly mileage >30, stress fracture history and <1 serving of calcium-rich food/day): 0-1 risk factors (11.1%), 2 risk factors (42.9%), or 3 4 risk factors (80.0%), p<0.001). CONCLUSIONS: Male adolescent runners exhibited lower body weight, BMI and spine BMD Z-score values. The risk of low BMD displayed a graded relationship with increasing risk factors, highlighting the importance of using methods to optimise bone mass in this population. PMID- 29461219 TI - MODIFIED ANTEROLATERAL SURGICAL APPROACH IN TOTAL HIP REPLACEMENT. AB - In this paper, we have studied the difference between classic Watson Jones anterolateral approach and modified anterolateral approach started in our institution from 2004 y. in group of patients with BMI more then 30 - 412 patients, mean age was 66,5 y., male -157 (38.2%), female - 255 (61,8%). Primary diagnosis were: Idiopathic osteoarthritis - 379 (92%), Rheumatoid ostheoarthritis - 16 (4%), DDH - 12 (3%). All surgeries were performed on supine position. All surgeries were performed by single surgeon. In 321 (78%) of cases modified approach was used. Only uncemented implants from Zimmer-Biomet were used. In our study we conclude that the differences between these two approaches were hip flection, gluteus medius partial detachment and oblique incision of the skin, but these three point makes the approach much more easier to perform because in flexed position M.Gluteus Medius and M. Tensor Fascia Lata are more relaxed and in 4th position oblique incision protects the skin from damage caused by femoral rasp. PMID- 29461220 TI - INDEXES OF CYTOKINE PROFILE OF BLOOD IN PATIENTS WITH COMPLICATED ERYSIPELAS. AB - The cytokine blood profile in patients with complicated erysipelas was investigated. It was found that in patients with complications of erysipelas (gangrene, phlegmon, abscess, thrombophlebitis of the subcutaneous veins of the shin) levels of pro-inflammatory cytokines IL-1beta, TNF-alpha, IL-2, IL-6 in serum significantly increase and level of anti-inflammatory cytokine IL-4 increases slightly, as well as was found a significant increase in coefficients reflecting the ratio of pro-inflammatory and anti-inflammatory cytokines, which indicates the prevalence in the blood of examined patients with complications of erysipelas an anti-inflammatory properties. A more significant increase in pro inflammatory cytokines serum levels is typical for patients with destructive forms of erysipelas - phlegmonous and gangrenous, a slight increase - for patients without purulent-necrotic component of complication (thrombophlebitis of the subcutaneous veins of the shin). In the future we plan to study pharmacological correction of shifts in cytokine blood profile with drugs with immunomodulating properties in patients with complicated erysipelas. PMID- 29461221 TI - BILATERAL ADRENOCORTICAL CARCINOMA: CASE REPORT AND REVIEW OF LITERATURE. AB - Adrenocortical carcinoma is a very rare and aggressive endocrinological malignancy arising from the adrenal cortex. The estimated incidence is 1 per million people, with an estimated 5-year survival rate of 16-47%. It can be bilateral in roughly 2-10% of cases, but the data is scarce and there is no conclusive evidence whether the contralateral mass is an independent tumor or a metastasis from the other adrenal gland cancer. Radical surgical excision is the only curative treatment. Therefore, careful pre- and intraoperative surgical planning is critically important. Open adrenalectomy has historically been the gold standard approach for surgical treatment of adrenocortical carcinoma. Laparoscopic adrenalectomy has emerged as a minimally invasive alternative, but its oncological safety and effectiveness has long been under debate. Current evidence suggests that in experienced hands laparoscopic adrenalectomy is as safe and effective as its open counterpart in the treatment of localized adrenocortical carcinoma and the adrenal masses <=10 cm. Urologists have been tempted to apply laparoscopy also to bilateral disease, although the need to reposition the patient and a longer operative time can be limitations. Given the rarity of adrenocortical carcinoma and the lack of quality evidence for the bilateral disease, we used the conventional narrative strategy to review the available literature. We also report a case of nonfunctioning bilateral adrenocortical carcinoma in a 65-year old man, who was operated on with simultaneous bilateral laparoscopic adrenalectomy for suspected localized (stage 2) disease, which proved to be bilateral locally advanced carcinoma (stage 3). Postoperatively, the disease rapidly progressed to the fatal outcome. The case once again highlights the importance of detailed operative planning and the need of imaging studies as close as possible to the date of planned surgery.

AB - The aim of this study was to assess and develop an effective computer technology assisted method for improved treatment of dental implant patients. Both an experimental and clinical assessments were conducted. The experimental part was performed to develop the mathematical models for calculating and analyzing the tensely deformed condition (TDC) in the system "non-removable prosthesis - dental implant - lower jaw " (PIJ). Clinical study was conducted on 76 patients with previously placed dental implant supported prostheses in the posterior parts of the lower jaw (with and without signs of bone receding around the implants) allocated into three groups. Results of the study allowed the authors to suggest an effective computer technology supported method for assessing the required angles of dental implants, which provides an opportunity for individual calculation of the dental implant in the bone of the mandible depending on the direction of functional load. PMID- 29461223 TI - NON-REMOVABLE DENTURE PROTOTYPES, EFFECTIVE IN DENTAL IMPLANTATION. AB - Temporary prosthesis transformed into a prosthetic prototypes and manufactured by CAD/CAM technologies (computer copy milling) are used to specify the final form of future permanent restoration and to correct occlusal relationships, vertical size of non-removable dentures, and their occlusal surfaces. A progressive loading on bone tissue in the implantation area and soft tissues formation, have been assessed. In this regard, the choice and placement of temporary mini implants, as the supports for non-removable denture prototypes for the period of osseointegration of two-stage intraosseous dental implants, are the issues of great importance. Temporary dental implants are the object of complex loads of different magnitude, duration and direction. The action of the prosthesis is closely related to load delivery to the surface of dental implant between the components of the system - "implant-temporary prosthesis". According to the study results, minimization of the momentum acting on temporary implants in the mesiodistal direction allows reducing stress level in the areas of permanent implant placement.

AB - On the background of microecological changes in the gastrointestinal tract, mineral and protein metabolism is disrupted, biochemical changes occur in the phosphorus-calcium metabolism in the bones of the skeleton and hard tissues of the teeth. The aim of the research was to study the activity of the caries process, characterized by progressive decalcification, under conditions of microecological changes in the intestine and its effect on the processes of endogenous calcium assimilation in adolescence. Within the frames of the research 68 adolescents aged 11 to 17 years with various degrees of pathology of the gastrointestinal tract were examined. The data of the performed studies showed that in patients with more severe changes in the intestinal micro flora, the prevalence and intensity of dental caries are significantly higher (83.4% on average DMFT 5.0) than in adolescents with mild dysbiosis (71.8% DMFT 3.2% ), and in the patients with normal intestinal micro flora - the parameters were minimal. Estimating and comparing the interrelation between the incidence of caries and the presence of diseases of the gastrointestinal tract in adolescents, a directly proportional dependence of the DMF index on age was found, but the greatest increase in the individual level of incidence of dental caries (SIC) was observed in adolescents aged 14-16 (SIC=0,42) with severe gastrointestinal pathology GIT. Thus, significant changes in dental status detected in adolescents with pathology of the gastrointestinal tract confirm the validity of complex treatment and preventive dental care, considering the processes occurring in the body and the oral cavity, as well as the systematic, purposeful dental care and the allocation of patients with gastrointestinal pathology (GIT) in a separate group.

AB - : The aim of the research was to study changes of EMG-activity of masticatory muscles after functional therapy at the retention stage after active orthodontic treatment. MATERIAL AND METHODS: The study included 55 people at the beginning of the retention stage after active orthodontic treatment. Patients of the study group were carried out functional therapy using proposed appliance during 3 month. The control group used the standard retention method. Clinical examination and EMG of masticatory muscles was performed to all patients at the beginning of the retention and in tree months. RESULTS AND CONCLUSION: In 3 month of functional correction EMG-activity of the masticatory muscles significantly decreased and became synchronous and symmetrical in patients of the study group, that proved the effectiveness of the method of functional therapy at the beginning of retention stage after active orthodontic treatment. PMID- 29461226 TI - CORRELATION BETWEEN THE ORAL HYGIENIC CONDITION AND PSYCHO-SOCIAL FACTORS IN THE ELDERLY POPULATION OF IMERETI. AB - The purpose of the study is to determine the correlation between the oral hygienic condition and the psycho-social factors in the elderly population of Imereti. The research was based on the findings of 374 persons who were older than 50 years of age from the contingent of Kutaisi Regional Dental Center and From the contingent of the boarding house of the Kutaisi elderly and disabled people. The oral hygienic level was determined by the method of GreeneVermilion, and we used the E. Ambjornsen method to evaluate hygienic conditions of removable prostheses. The difference between the groups was determined by F Fischer's criterion; The relationship between the factors was determined by the correlation analysis - the Spearerman's Rank Test. Correlation analysis shows the level of hygiene and behavioral factors that show positive correlation with good hygienic levels of the mouth: self-efficiency r=0.113; P=0.029; Self control r=0.104; P=0.045; Optimism r=0.144; P=0.005; Social opportunities r=.144; P=0.005; Psychosocial function r=0.227; P=0.000; Self-service r=0.127; P=0.014; Motor function r=0.128; P=0.013; Reliable positive correlation with a bad hygienic level - the need for other medical assistance - r=0.327; P=0.000; Disorders of behavior - r=0.378; P=0.000; Chronic pain - r=0.484; P=0.000; Decreased mobility r=0.492; P=0.000; Inconvenience - r=0.533; P=0.000; Physical weakness - r=0.487; P=0.000; Disorientation - r=0.403; P=0.000; Bad memory - r=0.417; P=0.000; Psychological weakness - r=0.462; P=0.000; Lack of support - r=0.318; P=0.000; The oral hygienic level in elderly persons correlates with psycho-social and behavioral factors. PMID- 29461227 TI - [THE DIFFERENTIATED APPROACH TO PREVENTION OF NEURAL TUBE DEFECTS IN CHILDREN]. AB - Neural tube defects occupy second place in frequency after the defects of the cardiovascular system. The folate metabolism violation and hyperhomocysteinemia in women are proved to be the leading risk factors for the NTD of the fetus. Polymorphism of the 5,10-methylenetetrahydrofolate reductase gene (MTHFR) is a genetic determinant of folate metabolism violation. Admission of folic acid in a standard dose of 0.4 mg and / or the use of fortified foods does not allow reaching the protective level of folic acid if there is a mutation of the MTHFR gene or when several risk factors combine, which requires a higher dose of folic acid. The aim of the study is to develop an algorithm for the identification of women of reproductive age with the risk of having a child with NTD and to apply differentiated approach to the choice of a preventive dose of folic acid. A retrospective analysis of NTD cases in the Odessa region (Ukraine) for 2000-2013 was carried out. The frequency of the birth of children with CNS defects and NTD, risk factors of NTD in children were studied. Mothers and their children with NTD were evaluated for the level of folic acid, homocysteine and the presence of C677T and A1298C MTHFR polymorphisms. The incidence of spina bifida aperta is 4.9 per 10,000 newborns. Two groups of significant risk factors for the NTD in children were identified: 1) risk factors that can be eliminated - the absence of preconceptional prevention of NTD with folic acid (AR 0.4), second-hand tobacso smoking (AR 0.33), fever/hot baths in the first trimester of pregnancy (AR 0.64), use of well water for cooking (AP 0.44); 2) risk factors that can not be eliminated, and which indicate a genetic risk of NTD - a family history of a stroke, heart attack, thrombosis, congenital malformations, malignant tumors (AR 0.54-0.7), an obstetrical history of miscarriage (AR 0.56 ), mother's diseases (varicose disease, obesity), NTD in other children in this family (AR 0.74). The mothers of children with NTD showed a decreased level of folic acid and an increased level of homocysteine in addition to the correlation of hyperhomocysteinemia with the mutations of the MTHFR gene. The algorithm for assessing the individual risk of having a child with NTD includes the evaluation of risk factors. If a genetic factor of folate metabolism violation or environmental risk factors that can not be eliminated are found, we recommend an additional examination. It includes determining the level of homocysteine and the MTHFR polymorphisms (in the case of hyperhomocysteinemia), which will identify the required dose of folic acid. PMID- 29461228 TI - A STUDY OF ADAPTIVE REACTIONS OF THE CARDIORESPIRATORY SYSTEM IN PSYCHOEMOTIONAL STRESS CONDITIONS. AB - The article presents modern data on the physiological mechanisms study of the stress resistance development, which occurs in medical students in the dynamics of studying in higher educational institution in junior courses (1-3 courses). The adaptive reactions of the cardiorespiratory system in conditions of psychoemotional load were studied. Results showed that development of adaptation syndrome in those conditions greatly depends on speed of formation and intensity level of intersystem integration in cardiorespiratory system. That relation is revealed most of all on the background of physical activity (load on bicycle ergometer to the full). The variability of stages of adaptation development was found out. In first group of students the first stage of adaptive syndrome is characterized by activation of non-specific adaptive mechanisms (1st year of studies), that is naturally replaced by second stage - specific adaptive reactions, when the intellectual work capacity increases on the background of rationalization of its autonomic supply. In second group of students the second variant of adaptation development occurs - non-specific adaptive mechanisms (1st stage) on the 2nd year of study are changed by the stage of specific adaptation (2nd stage), that is accompanied by excessive psychophysiological indexes. On the 3rd year of study it leads to the depletion of adaptive capabilities (3rd stage). In third group of students the stage of activation of non-specific adaptive mechanisms was rapidly changed by their depletion, that was accompanied by decrease of intersystem integration and intellectual workability. Therefore, the formation of adaptive optimum occurs only in 40% of students. The majority (60%) of students-young women show either the initially insufficient adaptive capabilities, or excessive adaptation. Both insufficient and excessive adaptation naturally leads to psychological and autonomic disorders followed by appearance of psychosomatic neurotic manifestations. The prospects of future research from our point of view should lie in further investigation of gender peculiarities of adaptive reactions development up to psycho-emotional stress that develops in conditions of studying in university. That will make an opportunity to reveal the features of mechanisms of resistance formation depending on gender.

AB - Based on the study, data on the compliance of physicians in compliance with national and international protocols for the diagnosis and treatment of hypertension based on the principles of evidence-based medicine were revealed. The obtained data testify to the presence of facts not observing the recommended protocols. In addition, on the basis of the data obtained, insufficient level of joint responsibility was determined, both on the part of patients and on the part of doctors. The result of not full compliance with the protocols for diagnosis and treatment of hypertension, as well as insufficient adherence to the principles of joint responsibility were facts not reaching the target level of blood pressure. This work allows us to determine the further path of development of studies on arterial hypertension and ensuring all levels of prevention. PMID- 29461230 TI - [CLINICAL AND PSYCHOLOGICAL CORRELATIONS IN FIBROMYALGIA PATIENTS]. AB - The features of clinical symptoms, neurotic disorders and the level of subjective control were studied in patients with fibromyalgia. The analysis of relationship between the level of subjective control and neurotic symptoms (asthenia, depression, anxiety, hypochondria) depending the severity of main clinical manifestations of the disease was carried out. It was found that high intensity of fatigue, muscle pain, stiffness, insomnia, and an increase in the number of diagnostic tender points contribute to the formation of inverse correlation between the level of subjective control and neurotic disturbances. Thus, the increase of the externality of the level of subjective control allows indicating to the formation of patients' passivity in relation to their disease, the lack of adherence to prescribed course of treatment (low compliance). Although drug therapy is the main component of complex treatment of fibromyalgia patients, patients require significantly more - successful treatment requires active involvement of patients in the therapy process, as well as changes in their attitudes and lifestyle, which can be achieved by training in so-called "schools" for patients, use of psychotherapeutic methods. PMID- 29461231 TI - EFFICIENCY OF BIOFEEDBACK THERAPY IN COMPLEX TREATMENT OF RHEUMATOID ARTHRITIS PATIENTS. AB - Biofeedback is the process of gaining greater awareness of many physiological functions primarily using instruments that provide information on the activity of those same systems, with a goal of being able to manipulate them at will. In this work, the analysis of efficiency of biofeedback therapy in treatment of patients suffering from rheumatoid arthritis (RA) is carried out. This analysis was fulfilled by studying the dynamics of clinical, laboratory and psychological (level of subjective control) indices and their comparison in patients of main and control groups before and after the treatment. During the course of combined therapy alongside biofeedback therapy, an analgesic and anti-inflammatory effects, and improved functional capabilities were noticed in the patients. Thus, the additional use of biofeedback mechanism in complex treatment of RA patients promote increased efficiency of medical and rehabilitation process and improvement of level of self-control in the patients. PMID- 29461232 TI - NEPHROPATHY IN EARLY RHEUMATOID ARTHRITIS PATIENTS: DOES A SIGNIFICANT RISK EXIST? AB - Objective of the study layed in assessment of the pathophysiological relation between cell-mediated immunity (tumor necrosis factor-alpha (TNF-alpha) inflammatory cytokine) activation and renal dysfunction in the patients with early rheumatoid arthritis. We analyzed the data from 35 early rheumatoid arthritis (RA) patients of average age of 50,71+/-2,25 years (ranged 18-76 years, 80% of women) with 9,21+/-0,43 months mean duration of the disease by the time of the study initiation. Urine and blood tests were performed to verify the main indicators of kidney function and inflammation cytokines significant interaction. All signs of renal dysfunction at the baseline in the patients with early RA were associated with glomerular filtration rate decrease and excretion of urine protein increase. Dynamics of albuminuria, according to the analysis of variance for one-factor scheme, were significantly determined by the state of disease activity, reflecting the severity of joint damage. High urine beta-2 microglobulin level was significantly associated with the expression rate of main inflammatory cytokines as per binary regression analysis. The obtained dependence showed the dynamics of expression of tubular disorders in early RA with a progressive deterioration which did associate with the levels of TNF-alpha expression, and variety of the urine misroglobulin rates in the interval 200-350 MUg/L. Reliable correlation (r=0.51, p<0.05) between beta-2-microglobulinuria and TNF-alpha levels was clearly shown, revealing the relationship described by the formula MGU=- 81+937*log10 (TNF-alpha) as per regression analysis. The severity of tubular damage in early RA is associated with TNF-alpha expression, especially in the patients with TNF-alpha above 250 pg/mL, when microalbuminuria rates were significantly higher (p=0.00043). We identified robust data that in the early RA patients with high TNF-alpha, the number of reported cases of microalbuminuria was significantly higher than in those with low levels. PMID- 29461233 TI - PECULIARITIES OF QUALITY OF LIFE IN PATIENTS WITH GASTROESOPHAGEAL REFLUX DISEASE. AB - Many studies showed, that quality of life (QL ) is affected in case of gastroesophageal reflux disease (GERD). Numerous questionnaires with a wide variety of characteristics have been developed for the assessment of GERD. The current study aimed to determine the QL changes of patients with GERD. The sample consisted of 100 patients with GERD. We also formed control group, which consist of 50 practical healthy patients (without GERD). In case group we formed two subgroups- GERD with Esophagitis and GERD without Esophagitis. For QL measure we used SF-36 questionnaire. In case group 58 patients were male and 42 were female. GERD without Esophagitis subgroup included 71 cases, 41 of which were diagnosed in men and 30 in women. The mean age of this subgroup was 35.3+/-5.2 years. The second clinical subgroup is gastroesophageal reflux, with eosophthalic patients, which consisted of 29 cases. 17 patients in this subgroup were male and 12 female. The mean age of this subgroup was 35,4+/-5,3 years. The most affected subscales of patients with GERD were "Role physical functioning", "General health", "Role emotional functioning" comparing with control group according SF 36 questionnaire. In the case of GERD without an esophagus, the most affected were "Role physical functioning" and "Role emotional functioning" subscales. Regardless of the type of subgroup, QL "Bodily pain" and "General health" subscal's scores were lowIn case group patients, who have BMI>25 kg/m2 have lower scores of QL compared to the group GERD BMI<25kg/m2.

AB - Aim of study- estimate the influence of the metformin therapy on the sCD40-ligand and sVE-cadherinlevels among patients with acute myocardial infarction and concomitant type 2 diabetes mellitus. The study included44patients with AMI and type 2 diabetes whichweredividedintotwo groupsdependingonthe glucose lowering drugs they have been taken: I group - 21patients who have been taken metformin; II group - 23patients, who have been taken short-acting insulin. Accordingtotheobtainedresults using of metformin as a glucose lowering drug in comparison with patients who have been taken short-acting insulin causes faster decreasing of the sCD40L level (-29,3% and -24,4% accordingly; r<0,05). Whereas there was no significant differencesin the dynamics of sVE-cadherinlevels (-22,4% and -19,2% accordingly; r>0,05). Positive influence of them et form in on thes CD40-ligand level probably is caused by the inhibition of the Akt-kinase phosphorylation responsible for the activation of the nuclear factor kappa-b which controls expression of the immune response genes, particulary CD40. It leads to the inhibition of the thrombocytes activation and differentiation of the monocytes to the macrophages able to product proatherogenic factors. It was established that metformin therapy among patients with acute myocardial infarction and diabetes mellitus type 2 leads to the faster decreasing of sCD40 ligand in comparison with insulin therapy, which can contribute to the improvemenet of the prognosis in this cohort.

AB - The urgency of the problem of metabolic syndrome (MS) is due to the high prevalence and risk of developing cardiovascular complications. Purpose of the study - to investigate the degree of adherence to the Mediterranean diet of the studied sample using the MedDietScore (MDS) questionnaire and to assess the association of score of MDS with the components of metabolic syndrome. A cross sectional study was conducted, during which a clinical, laboratory examination and questioning of 839 patients was carried out. For assessment of the relationship between the MS, its components and the average MDS score multivariate logistic regression analysis was used. The average score of MDS in the studied population was 20.91 (Me=21.00). The mean MDS score was statistically significantly lower in patients with MS components, compared with patients who did not have these components. The inverse association between adherence to the Mediterranean diet and the components of the MS was revealed. PMID- 29461236 TI - FEATURES OF EXCRETION OF MELATONIN IN URINE IN PATIENTS WITH TYPE 2 DIABETES MELLITUS AND NON-ALCOHOLIC FATTY LIVER DISEASE WITH MANIFESTATIONS OF FIBROSIS AND ITS RELATIONSHIP WITH CERTAIN METABOLIC AND IMMUNOLOGICAL INDICATORS. AB - To study the features of secretion of melatonin in the urine in patients with DM type 2 and NAFLD with manifestations of fibrosis and its relationship with some metabolic and immunological parameters, 23 patients with DM type 2 and NAFLD were examined. The degree of fibrosis in patients was diagnosed on the basis of static elastography and the study of indirect fibrosis markers 16 persons (72%) diagnosed with mild fibrosis (F0-F1 on METAVIR), 5 people (18.2%) - with moderate fibrosis (F2-F3 on METAVIR). Only 2 (8.7%) patients did not have any fibrotic disorders, so they were excluded from the further study. All patients underwent determination of melatonin excretion of albumin and in daily urine, as well as the determination of homocysteine in the blood. The level of excretion of melatonin in the urine in patients with DM type 2 and NAFLD did not depend on the degree of fibrosis and on the average was 89.50+/-16.66 mmol/day, which exceeded the reference values. It has been established that the increase in melatonin level in patients with DM type 2 and NAFLD is associated with the presence of fibrotic changes in the liver and a decrease in the activity of the inflammatory process. In addition, a direct correlation was found between the excretion of melatonin and homocysteine (r=0.43), as well as between melatonin and albumin excretion in the urine (r=0.20). Thus, an increased level of excretion of melatonin in the urine can be not only a marker of liver fibrosis, but also a predictor of cardiovascular disorders in patients with DM type 2 and NAFLD. PMID- 29461238 TI - EFFECTIVE TREATMENT OF CHRONIC HEPATITIS C VIRUS INFECTIONS WITH DIRECT ACTING ANTIVIRALS IN PRISONS SYSTEM. AB - Hepatitis C is a widespread infectious disorder, accounting for chronic hepatic inflammatory condition - hepatitis, hepatic cirrhosis and hepatocellular carcinoma throughout the world. In Georgia, where the incidence of HCV infection in population is highest among eastern European countries, hepatitis C represents one the most actual problems of healthcare system. The aim of the study was to identify the efficacy of antiviral therapy and management of side effects in HCV infected patients. In the patients under observation with type I genotype, the rapid viral response (RVR) was negative in 100%. End of treatment response (EOT) was negative in 100%, and stable viral response (SVR) was negative in 99.3%. In patients with type II genotype the rapid viral response (RVR) was negative in 100%, end of treatment response (EOT) was negative in 100% and stable viral response (SVR) was negative in 100%. In patients with type III genotype: the rapid viral response (RVR) was negative in 100%. End of treatment response (EOT) was negative in 100% and stable viral response (SVR) was negative in 97%. Thus, HCV infection is widespread in correction department institutions. According to our study results, the final outcomes of antiviral treatment completed within the frames of this program, side effects developed during the course of treatment and their management are not significantly different from the results of antiviral treatment conducted in other population. Regardless of different psychological setting present in this type of institutions, this program is ongoing successfully and the observed results indicate on the importance of its continuation. PMID- 29461237 TI - [EVALUATION OF QUALITY OF LIFE IN PATIENTS WITH METABOLIC SYNDROME]. AB - The aim of the research - to assess physical and psychological state of health of patients with metabolic syndrome. The total number of participants in the study was 300 people. All respondents were divided into three groups. The first group included 100 people practically healthy, the second group 100 people without MS and the third group 100 people with a reliable diagnosis of the metabolic syndrome. To assess the physical and psychological components of the QOL, the "SF 36 Health Status Survery" questionnaire was used. The results of the study showed that the indices of the physical and psychological components of QOL in patients with metabolic syndrome were reduced by 3 (p<0.05) compared to the control group, which indicated the effect of the metabolic syndrome on QL. In patients with MS compared with the control group (1 group), the psychological component as a vital activity was reduced by 45%, role functioning due to emotional state by 55%, mental health by 33%, social functioning by 50%. The results of the questionnaire on the Special Questionnaire of the Hospital Scale of Anxiety and Depression (HADS) for the purpose of a detailed analysis of anxiety and depression showed that the level of anxiety and depression on the HADS scale depended on the duration and components of the MS. Indices of the physical and psychological component of QL in patients with MS significantly lower (p <0.05) comparing with the control group (practical healthy) and with the group without MS. The decrease in the physical (66.5%) and psychological (74%) state of QL health depends on the duration of the disease and on the components of the metabolic syndrome.

AB - In addition to accumulation and metabolism of triglycerides, white adipose tissue is recognized as the active endocrine organ, whose dysfunction is associated with the development of a wide range of diseases. The secretome of adipocytes is represented by a wide range of adipokines, which vary in depot and sex-specific manner. In addition, adipokines have diverse biological effects, correlations with different metabolic features and functions. In this review, the data on biological effects, origin and the clinical significance of adipokines are discussed. The influence of adipokines on metabolism, sensitivity to insulin, vascular homeostasis, angiogenesis, repair, inflammation and immune cells are shown. Visceral adipose tissue accumulation is accompanied with adipocytes hypertrophy and overproduction of such proinflammatory and proaterogenic molecules like resistin, visfatin, vaspin, tumor necrosis factor, interleukin 6, lipocalin, glypican 4, RBP4 etc. There is a tight correlation between these adipokines level and development of insulin resistance, type 2 diabetes, cardiometabolic complications and cancer. Thus, adipokines represent a group of informative biomarkers for the diagnostics of metabolic disorders and the prediction of the outcome of the wide range of diseases. The study of the effects and mechanisms of the action of adipokines is the basis for determining new targets for therapy. PMID- 29461240 TI - THE ROLE OF FRACTALKINE AND MONOCYTE CHEMOATTRACTANT PROTEIN-1 IN THE PROGRESSION OF ASTHMA. AB - To improve the effectiveness of diagnosis and prediction of adverse asthma comorbid conditions based on research of clinical manifestations features, functional disorders of the airways and endothelial dysfunction. 79 patients were selected for the study. All the patients were divided into 3 groups: group 1 - patients with asthma (n-22); group II (n-24) - patients with asthma + diabetes mellitus type 2; group III (n-33) - patients with asthma + obesity + arterial hypertension (AH) and control group (n-17) - healthy people. All the patients underwent clinical examination. Spirography indicators were tested, and full patients' examination was conducted. The levels of fractalkine (CX3CL1) and Monocyte Chemoattractant Protein - 1(MCP-1) were determined by Enzyme-linked immunosorbent assay (ELISA) test using Ray Bio(r) Human Fractalkine system manufactured by Ray Biotech, Inc., USA; "Human MCP-1" (eBioscience, Austria), respectively. Statistical processing of parameters of endothelial function, MSR-1 andCX3CL1, depending on comorbid pathology, has identified statistically significant elevated level of the separametersinall studied groups. The most pronounced changes of both parameters were registered in group 2 patients, indicative of the most significant manifestations of endothelial dysfunction in this patient group.Assessment of endothelium dysfunction markers depending on external respiration function was performed. It has been found out that MSR-1 affects vital pulmonary capacity (chi2=14.466; r=0.002) and forced expiratory volume in 1 second (FEV1) (chi2=8.471; r=0.037). Besides, CX3CL1 exerts influence on these parameters as well (chi2=19.385, r=0.001); (chi2=11.476, r=0.009), respectively. The decrease in rate parameters, in particular, FEV1, MEF 25, MEF 50, and MEF 75, was identified in all patient groups. Based on these data, we can assume that patients with a combination of asthma and diabetes mellitus type 2 demonstrate more cases of endothelial malfunction, leading to the worsening of respiratory function, compared to the group with asthma, obesity and arterial hypertension and a group without comorbidity. PMID- 29461241 TI - MEASUREMENT OF PERSONAL RISK BEHAVI-OR IN OCCUPATIONAL RISK STUDIES AMONG HEALTH CARE WORKERS. AB - Risky behaviours, particularly illegal and heavily stigmatized behaviours, are difficult to measure through self-report in both high risk groups and the general population. Underreporting can result in substantially biased estimates of non injection drug use (IDU) risk of hepatitis C virus (HCV) infection. We hypothesized that asking about the existence of social networks injection drug use may be a useful marker of IDU. A cross-sectional survey of physicians and nurses was conducted in seven hospitals in Georgia. Based on survey responses participants were categorized into three IDU risk groups: ever used injecting drugs (Self IDU), reported a friend, family member or colleague used injecting drugs (Associate IDU), or reported neither (No IDU). Testing on anti-HCV was done using third generation ELISA methods. Both unadjusted and adjusted prevalence ratios between IDU risk groups and HCV prevalence were estimated. Of the 1312 (82.2%) participants, 10 (0.8%), 75 (5.7%), and 1227 (93.5%) were categorized as Self IDU, Associate IDU and No IDU, respectively; with HCV prevalence of 20%, 9.3% and 4.6%, respectively (p=0.016). The association was due primarily to women's reports. Those who reported some IDU risk were more likely to report other personal risk behaviors (e.g., multiple sex partners) and occupational risk behaviors (e.g., frequent exposure to blood and body fluids). This study represents a start of measurement development by assessing the potential usefulness of a marker to measure of IDU. Improved measurement of stigmatized behaviors is needed for confounding adjustment to improve estimates of occupational risks of blood-borne infections. PMID- 29461242 TI - PHOTODYNAMIC TREATMENT WITH NANOEMULSIFIED 5-AMINOLEVULINIC ACID AND NARROW BAND RED LIGHT FOR FIELD CANCERIZATION DUE TO OCCUPATIONAL EXPOSURE TO ULTRAVIOLET LIGHT IRRADIATION. AB - Actinic keratosis (AK) is a premalignant epithelial disease that develops on skin chronically exposed to ultraviolet-light. For outdoor workers, AK is an occupational hazard with a potential for malignant transformation into squamous cell carcinoma. Various topical treatments are used to treat AK's. Photodynamic therapy (PDT) promises the highest cure rates. We performed a prospective single center trial evaluating effects of PDT treatment for field cancerization due to occupational exposure to ultraviolet light irradiation in patients unresponsive to the treatment regimen with topical diclofenac gel. For PDT, a nanoemulsified 5 aminolevulinic acid (5-ALA) formulation was combined with narrow band red light irradiation with a peak wavelength of 635 nm and a total light intensity of 37 J/cm2. Clearance rate and adverse events were recorded. Thirty patients with a mean age of 77+/-10.5 years (26 males and 4 females) were included in the trial. They received between one and nine PDT sessions. Mean pain during PDT was scored at 6.8+/-2.8 using the visual analogue scale. Patients exhibited a mild immediate erythema after PDT. Among the patients, who tolerated PDT, a complete clearance was achieved in 93.3%, and >90% clearance - in 6.7%. Pain management was performed by cold-air analgesia. In conclusion, PDT with nanoemulsified 5-ALA and narrow band red light irradiation is an effective and safe treatment for occupational field cancerization without systemic toxicity. Adherence to this treatment is much better than to topical treatment. PMID- 29461243 TI - [ULTRASTRUCTURAL CHARACTERISTICS OF RATS TESTICLES UNDER SPERMATIC CORD STENOSIS AND AFTER BLOOD FLOW RESTORATION BY DIFFERENT METHODS]. AB - Hemodynamic disorders in the testicles cause chronic organ hypoxia with damage of its stroma and seminiferous tubules, which plays a leading role in the pathogenesis of the testicular form of male infertility development. The aim of the work was to establish the features of ultrastructural reorganization of the testicles tissue and its vascular bed under circulatory hypoxia conditions and after restoration of blood flow in the organ. The study was conducted on 84 white adult male rats. The control group consisted of 12 intact animals. The experimental group was divided into 3 series: with stenosis of the spermatic cord (48 animals), with stenosis of the spermatic cord and its recanalization on the 3rd day without correction (12 animals) and with stenosis of the spermatic cord and its recanalization with correction on the 3rd day (12 animals). Under conditions of dosage spermatic cord stenosis (when the ligature is applied) in the remote monitoring period, with electron microscopic study, were detected destructive changes of spermatid and spermatozoa, which were combined with significant focal intracellular and extracellular edema. In part of the cells heads were deformed, the acrosomes were sophisticated and fragmented. At one stage decompression of the spermatic cord (removal of the stenosing ligature on the third day), the above-described changes in accordance were deepened. At 14th day of the observation, collagen fibers and an electron-transparent amorphous component were found in the perivascular space. When the proposed method of dosed decompression of the spermatic cord (successive removal of three stenosing ligatures of different diameters) has been applied changes in the testicles parenchyma and its intraorganic vessels were less severe. Functional activity of the testicle after correction of reperfusion changes, was not significantly affected, what was proved by the presence in seminiferous tubules lumen of spermatozoa mature forms. PMID- 29461244 TI - EFFECT OF FREE RADICALS ON CALCITONIN-GENE-RELATED PEPTIDE MEDIATED VASODILATION. AB - It is known that in some pathological conditions, due to the formation of a large number of free oxygen radicals, the cardiovascular system is severely affected. However, the effect of free radicals on CGRP-mediated vasodilation remains unclear. The aim of this work was to study the effect of free radicals on CGRP mediated neurogenic vasodilation on preparations of an isolated rabbit lingual artery. The experiments were performed on the lingual artery preparations of 6 rabbits of the Chinchilla breed of both sexes. The contractile-relaxation activity of isolated preparations, both with intact endothelial layer and deendotelized, were studied in isometric mode on a strain-gauge unit using mechanotrons of the 6 MX1C type. Our experiments showed that free radicals can disrupt the reactivity of the vascular wall both in the presence and in the absence of endothelium-dependent relaxation factors and that is might be considered as a main conclusion of this study. PMID- 29461245 TI - [IMMUNOMORPHOLOGICAL ASPECTS OF BACTERIAL SENSITIZATION IN THE EXPERIMENT]. AB - This study investigates the morphological structure of lungs, liver and kidneys of the experimental animals. To reproduce the inflammation in maxilla-facial region under the periosteum of guinea pigs' mandible a suspension of S.aureus was inoculated. The infected site was exposed by a constant electric current of positive polarity of 5-10 MUA strength. Allergotests were used to determine the level of sensitization. Structural changes in the organs were determined by microscopic examination. The results of the study showed that as the contact with the antigen increased, the number of positive allergic tests also increased. Histologically, a generalized damage to the microstructure of the internal organs, depending on the degree of bacterial sensitization of the animals was observed. PMID- 29461246 TI - NEW TEMPERATE ENTEROCOCCUS PHAGE VB_GEC_EFS_2 WITH POTENTIAL OF LYSOGENIC CONVERSION. AB - Bacteriophages represent the widest group of viruses, from which only virulent phages are used as antibacterial agent. But the picture in the case of temperate phage is absolutely different; many lysogenic phages express gene products that have subtle effects on the phenotype of the host cell. This process is called lysogenic conversion. In present study we characterized new temperate Enterococcus faecium phage vB_GEC_EFS_2, which was isolated from river Mtkvari. The phage is a member of Siphoviridae family. Whole genome of phage vB_GEC-EfS_2 was sequenced and analyzed. Total length of the genome of phage vB_GEC_EFS_2 is 38 508bp, The assembly contains 65 ORFs, among them - 3 lysis genes , genes coded 13 structural proteins, 1 DNA replication-associated gene, 1 gene coded integration, 3 - lysis-lysogenic cycle regulation, 43 hypothetical proteins. One holin gene contained "Haemolysin XhIA" domain which is surface associated haemolisyn. We isolated and purified holin gene and determine its haemolitic activity alongside with vB_GEC_EfS_2 phage lysate. We clarified the XhIA domain function and role in protein's haemolytic nature and described another kind of lysogenic conversion. PMID- 29461247 TI - [ALKALOIDS OF UNDERGROUND PARTS OF GEORGIAN FLORA'S ACONITUM ORIENTALE MILL. AND ACONITUM NASUTUM FISCH. EX REICHEMB AND THEIR BIOLOGICAL ACTIVITY]. AB - The aim of research was to study underground parts of Aconitum orientale Mill and Aconitum nasutum Fisch exReichemb for the composition of biological active diterpenic alkaloids. The research object was underground parts of Aconitum species. Alkaloids sum was received from raw-material which was alkalined beforehand with chloroform extraction. From the results of research we established, that both species of Georgian flora's Aconitum contains alkaloids: lappaconitine, aconitine, karakoline. Underground parts of Aconitum orientale and Aconitum nasutum differ from eath other with composition of alkaloids spectrum. Underground parts of Aconitum orientale contains bases: ranaconitine, gigactonine, licoctonine, but underground parts of Aconitum nasutum contains: talitizamine, kamakonine, aconosine. Alkaloids' summary substances, which were received from underground parts of Aconitum species spread in Georgia, showed selective cytotoxic activity towards A-549 (lung carcinoma), DLD-1 (intestine adenocarcinoma), WS-1 (human normal fibroblasts). PMID- 29461248 TI - [RESTORATION OF SYMPATHO-PARASYMPATHETIC BALANCE IN HEART RATE VARIABILITY IN THE DEVELOPMENT OF PSYCHOEMOTIONAL STRESS AGAINST THE BACKGROUND OF TAURINE IN EXPERIMENT]. AB - In this fragment of the study, the change in the ratio of low (LF) and high frequency (HF) waves to the heart rhythmogram during prolonged immobilization (5 hours) of sexually mature white non-linear rats was studied by spectral analysis of heart rate variability, which causes psychoemotional stress and the accompanying vegetative equilibrium shift, indicating on the dysregulation of the sympatho-parasympathetic balance without and against the background of daily intraperitoneal injection of taurine (50 mg/kg) and its participation in the mechanisms of adaptive processes in the early poststress period (from 1 to 14 days). Spectral analysis of both absolute and relative indices of the I-th group (stress without taurine) revealed significant shifts in the frequency spectrum. On the first day after immobilization, the total power of the spectrum decreased by 4.3%, the HF component by 33.3%, and the level of VLF and LF-components increased by 25.5% and 25%, respectively, compared to the norm. On the 14th day after the immobilization, there is a decrease in tension, but the LF component is still above the norm by 5%. Calculations of the percentage ratios of the absolute values of the spectrum at different times of the post-stress period against the background of taurine injection showed that in the initial stage (immediately and on the first day after stress) a strong shift of activity toward sympathization occurs, and the absolute value of LF and VLF in the spectrum increased by 23,1% and 10.9% respectively. However, the complete restoration of the vago-sympathetic balance with the daily application of taurine occurs already on the 7th day after immobilization. The beneficial effect of taurine on the cardiovascular system was revealed when examining the scatterogram of the regression dependence of the heart rate, which revealed a smaller variation in heart rate and its stabilization on the 7th day after immobilization. Thus, the use of taurine immediately after stressful reactions is necessary to accelerate adaptive processes in the early post-stress period to prevent the development of stress pathology. PMID- 29461249 TI - THE ROLE OF NON-PROFIT ORGANIZATIONS IN HEALTHCARE SYSTEM: WORLD PRACTICE AND GEORGIA (REVIEW). AB - The health care market is substantially different from other areas of the economy and therefore the behavior of health care providers operating in the health care market is different, which is mainly related to the form of ownership. If the market is mainly characterized by the pursuit of maximum profit, medical services market has for some public good features. Because of this, non-profit hospitals in western countries are considered as an alternative form of commercial hospitals. The purpose of the research was to study the role of not-for-profit hospitals, and in this regard examine the situation of the medical market in Georgia. The existing literature about non-profit hospitals, relevant legislation and statistical data, scientific articles, and other related works. The majority of the hospitals in Georgia represent profitable (commercial) organizations. 41,1% of the hospitals owned by private insurance companies, 29,1% by individuals, 18,4% by other types of companies, 3,2% by other forms and 8% is state-owned. In contrast to this, more than 50% of the healthcare system of West Europe as well as USA is composed of non-profit (commercial) hospitals. In Georgia there is no sufficient motivation for operating of hospitals as non profit organizations. It is necessary to further adjust tax benefit in the Tax Code of Georgia and share European experiences. It is reasonable to increase the role of non-profit hospitals on the health care market that will increase accessibility to healthcare services for population and moreover. It will bring Georgian healthcare system close to the experience of civilized world. PMID- 29461251 TI - Axial propulsion with flapping and rotating wings, a comparison of potential efficiency. AB - Interest in biological locomotion and what advantages the principles governing it might offer in the design of manmade vehicles prompts one to consider the power requirements of flapping relative to rotary propulsion. The amount of work performed on the fluid surrounding a thrusting surface (wing or blade) is reflected in the kinetic energy of the wake. Consideration of the energy in the wake is sufficient to define absolute minimum limitations on the power requirement to generate a particular thrust. This work applies wake solutions to compare the minimum inviscid propulsive power requirement of wings flapping and in rotation at wing loading conditions reflective of hover through a state of lightly-loaded cruise. It is demonstrated that hovering flapping flight is less efficient than rotary wing propulsion except for the most extreme flap amplitude strokes ([Formula: see text] > 160 degrees ) if operating at large wake wavelength. In cruise, a larger range of flap amplitude kinematics ([Formula: see text] > 140 degrees ) can be aerodynamically more energy efficient for wake wavelengths reflective of biological propulsion. These results imply, based on the observed wing kinematics of continuous steady flight, that flapping propulsion in animals is unlikely to be more efficient than rotary propulsion. PMID- 29461250 TI - Ergodicity, hidden bias and the growth rate gain. AB - Many single-cell observables are highly heterogeneous. A part of this heterogeneity stems from age-related phenomena: the fact that there is a nonuniform distribution of cells with different ages. This has led to a renewed interest in analytic methodologies including use of the 'von Foerster equation' for predicting population growth and cell age distributions. Here we discuss how some of the most popular implementations of this machinery assume a strong condition on the ergodicity of the cell cycle duration ensemble. We show that one common definition for the term ergodicity, 'a single individual observed over many generations recapitulates the behavior of the entire ensemble' is implied by the other, 'the probability of observing any state is conserved across time and over all individuals' in an ensemble with a fixed number of individuals but that this is not true when the ensemble is growing. We further explore the impact of generational correlations between cell cycle durations on the population growth rate. Finally, we explore the 'growth rate gain'-the phenomenon that variations in the cell cycle duration leads to an improved population-level growth rate-in this context. We highlight that, fundamentally, this effect is due to asymmetric division. PMID- 29461252 TI - Dynamics of self-assembled cytosine nucleobases on graphene. AB - Molecular self-assembly of cytosine (C n ) bases on graphene was investigated using molecular dynamics methods. For free-standing C n bases, simulation conditions (gas versus aqueous) determine the nature of self-assembly; the bases prefer to aggregate in the gas phase and are stabilized by intermolecular H bonds, while in the aqueous phase, the water molecules disrupt base-base interactions, which facilitate the formation of pi-stacked domains. The substrate induced effects, on the other hand, find the polarity and donor-acceptor sites of the bases to govern the assembly process. For example, in the gas phase, the assembly of C n bases on graphene displays short-range ordered linear arrays stabilized by the intermolecular H-bonds. In the aqueous phase, however, there are two distinct configurations for the C n bases assembly on graphene. For the first case corresponding to low surface coverage, the bases are dispersed on graphene and are isolated. The second configuration archetype is disordered linear arrays assembled with medium and high surface coverage. The simulation results establish the role of H-bonding, vdW pi-stacking, and the influence of graphene surface towards the self-assembly. The ability to regulate the assembly into well-defined patterns can aid in the design of self-assembled nanostructures for the next-generation DNA based biosensors and nanoelectronic devices. PMID- 29461253 TI - Multifunctional devices based on SnO2@rGO-coated fibers for human motion monitoring, ethanol detection, and photo response. AB - In this study, we developed a multifunctional device based on SnO2@rGO-coated fibers utilizing plasma treatment, dip coating, and microwave irradiation in sequence, and finally realized highly sensitive human motion monitoring, relatively good ethanol detection, and an obvious photo response. Moreover, the high level of comfort and compactness derived from highly elastic and comfortable fabrics contributes to the long-term availability and test accuracy. As an attempt at multifunctional integration of smart clothing, this work provides an attractive and relatively practical research direction. PMID- 29461254 TI - Lesion detection and quantification performance of the Tachyon-I time-of-flight PET scanner: phantom and human studies. AB - The first generation Tachyon PET (Tachyon-I) is a demonstration single-ring PET scanner that reaches a coincidence timing resolution of 314 ps using LSO scintillator crystals coupled to conventional photomultiplier tubes. The objective of this study was to quantify the improvement in both lesion detection and quantification performance resulting from the improved time-of-flight (TOF) capability of the Tachyon-I scanner. We developed a quantitative TOF image reconstruction method for the Tachyon-I and evaluated its TOF gain for lesion detection and quantification. Scans of either a standard NEMA torso phantom or healthy volunteers were used as the normal background data. Separately scanned point source and sphere data were superimposed onto the phantom or human data after accounting for the object attenuation. We used the bootstrap method to generate multiple independent noisy datasets with and without a lesion present. The signal-to-noise ratio (SNR) of a channelized hotelling observer (CHO) was calculated for each lesion size and location combination to evaluate the lesion detection performance. The bias versus standard deviation trade-off of each lesion uptake was also calculated to evaluate the quantification performance. The resulting CHO-SNR measurements showed improved performance in lesion detection with better timing resolution. The detection performance was also dependent on the lesion size and location, in addition to the background object size and shape. The results of bias versus noise trade-off showed that the noise (standard deviation) reduction ratio was about 1.1-1.3 over the TOF 500 ps and 1.5-1.9 over the non-TOF modes, similar to the SNR gains for lesion detection. In conclusion, this Tachyon-I PET study demonstrated the benefit of improved time-of-flight capability on lesion detection and ROI quantification for both phantom and human subjects. PMID- 29461255 TI - Accuracy of radiotherapy dose calculations based on cone-beam CT: comparison of deformable registration and image correction based methods. AB - Radiotherapy dose calculations based on cone-beam CT (CBCT) images can be inaccurate due to unreliable Hounsfield units (HU) in the CBCT. Deformable image registration of planning CT images to CBCT, and direct correction of CBCT image values are two methods proposed to allow heterogeneity corrected dose calculations based on CBCT. In this paper we compare the accuracy and robustness of these two approaches. CBCT images for 44 patients were used including pelvis, lung and head & neck sites. CBCT HU were corrected using a 'shading correction' algorithm and via deformable registration of planning CT to CBCT using either Elastix or Niftyreg. Radiotherapy dose distributions were re-calculated with heterogeneity correction based on the corrected CBCT and several relevant dose metrics for target and OAR volumes were calculated. Accuracy of CBCT based dose metrics was determined using an 'override ratio' method where the ratio of the dose metric to that calculated on a bulk-density assigned version of the same image is assumed to be constant for each patient, allowing comparison to the patient's planning CT as a gold standard. Similar performance is achieved by shading corrected CBCT and both deformable registration algorithms, with mean and standard deviation of dose metric error less than 1% for all sites studied. For lung images, use of deformed CT leads to slightly larger standard deviation of dose metric error than shading corrected CBCT with more dose metric errors greater than 2% observed (7% versus 1%). PMID- 29461256 TI - High density nonmagnetic cobalt in thin films. AB - Recently high density (HD) nonmagnetic cobalt has been discovered in a nanoscale cobalt thin film, grown on Si(111) single crystal. This form of cobalt is not only nonmagnetic but also superconducting. These promising results have encouraged further investigations of the growth of the nonmagnetic (NM) phase of cobalt. In the original investigation, the cobalt film had a natural cobalt oxide at the top. We have investigated whether the growth of HD NM cobalt layers in the thin film depends on (i) a capping layer on the cobalt film, (ii) the thickness of the cobalt film and (iii) the nature of the substrate on which the cobalt film is grown. The results of such investigations indicate that for cobalt films capped with a thin gold layer, and for various film thicknesses, HD NM cobalt layers are formed. However, instead of a Si substrate, when the cobalt films are grown on oxide substrates, such as silicon oxide or cobalt oxide, HD NM cobalt layers are not formed. The difference is attributed to the nature-crystalline or amorphous-of the substrate. PMID- 29461257 TI - Atomic layer deposited high-k dielectric on graphene by functionalization through atmospheric plasma treatment. AB - Atomic layer-deposited (ALD) dielectric films on graphene usually show noncontinuous and rough morphology owing to the inert surface of graphene. Here, we demonstrate the deposition of thin and uniform ALD ZrO2 films with no seed layer on chemical vapor-deposited graphene functionalized by atmospheric oxygen plasma treatment. Transmission electron microscopy showed that the ALD ZrO2 films were highly crystalline, despite a low ALD temperature of 150 degrees C. The ALD ZrO2 film served as an effective passivation layer for graphene, which was shown by negative shifts in the Dirac voltage and the enhanced air stability of graphene field-effect transistors after ALD of ZrO2. The ALD ZrO2 film on the functionalized graphene may find use in flexible graphene electronics and biosensors owing to its low process temperature and its capacity to improve device performance and stability. PMID- 29461258 TI - Endothelial cell protein C receptor-dependent signaling. AB - PURPOSE OF REVIEW: Endothelial cell protein C receptor (EPCR), a transmembrane glycoprotein present on the surface of endothelial cells and other cell types, is an essential component of the protein C (PC) anticoagulant system. EPCR is also shown to play a critical role in mediating activated protein C (APC)-induced cytoprotective signaling. The purpose of this review is to outline the mechanisms of EPCR-dependent cell signaling and discuss recent findings made in this area. RECENT FINDINGS: Recent studies showed that the cleavage of protease-activated receptor (PAR)1 at a noncanonical site by APC-EPCR or the canonical site by thrombin when PC occupies EPCR induces beta-arrestin-2-mediated biased cytoprotective signaling. Factor VIIa binding to EPCR is also shown to induce the cytoprotective signaling. EPCR is found to be a reliable surface marker for identifying human hematopoietic stem cells in culture. EPCR, binding to diverse ligands, is thought to play a role in the pathogenesis of severe malaria, immune functions, and cancer by either blocking the APC-mediated signaling or by mechanisms that are yet to be elucidated. SUMMARY: Recent studies provide a mechanistic basis to how EPCR contributes to PAR1-mediated biased signaling. EPCR may play a role in influencing a wide array of biological functions by binding to diverse ligands. PMID- 29461259 TI - The flux of iron through ferritin in erythrocyte development. AB - PURPOSE OF REVIEW: Terminal differentiation of erythropoietic progenitors requires the rapid accumulation of large amounts of iron, which is transported to the mitochondria, where it is incorporated into heme. Ferritin is the sole site of iron storage present in the cytosol. Yet the role of iron accumulation into ferritin in the context of red cell development had not been clearly defined. Early studies indicated that at the onset of terminal differentiation, iron initially accumulates in ferritin and precedes heme synthesis. Whether this accumulation is physiologically important for red cell development was unclear until recent studies defined an obligatory pathway of iron flux through ferritin. RECENT FINDINGS: The iron chaperone functions of poly rC-binding protein 1 (PCBP1) and the autophagic cargo receptor for ferritin, nuclear co-activator 4 (NCOA4) are required for the flux of iron through ferritin in developing red cells. In the absence of these functions, iron delivery to mitochondria for heme synthesis is impaired. SUMMARY: The regulated trafficking of iron through ferritin is important for maintaining a consistent flow of iron to mitochondria without releasing potentially damaging redox-active species in the cell. Other components of the iron trafficking machinery are likely to be important in red cell development. PMID- 29461260 TI - Hemolysis and immune regulation. AB - PURPOSE OF REVIEW: Hemolytic anemias caused by premature destruction of red blood cells occur in many disorders including hemoglobinopathies, autoimmune conditions, during infection or following reaction to drugs or transfusions. Recent studies which will be reviewed here have uncovered several novel mechanisms by which hemolysis can alter immunological functions and increase the risk of severe complications in hemolytic disorders. RECENT FINDINGS: Plasma-free heme can induce the formation of neutrophil extracellular traps (NETs) through reactive oxygen species signaling. Although NETs protect the host against infections, in patients with sickle disease, they are associated with vaso occlusive crises. Heme may increase host susceptibility to infections by inducing heme oxygenase 1 (HO-1) in immature neutrophils, thereby inhibiting oxidative burst required for clearance of engulfed bacteria. In addition, heme impairs macrophage phagocytosis and microbial clearance through inhibition of cytoskeletal remodeling. Hemolysis can also favor anti-inflammatory immune cell polarization by inhibiting dendritic cell maturation necessary for effector T cell responses, inducing differentiation of monocytes into red pulp macrophages, important for iron recycling from senescent erythrocytes, and driving regulatory T-cell expansion through modulation of HO-1 expression in nonclassical monocytes. SUMMARY: Hemolysis breakdown products show remarkable effects on the regulation of immune cell differentiation and function. PMID- 29461261 TI - From dysmotility to virulent pathogens: implications of opioid use in the ICU. AB - PURPOSE OF REVIEW: Gastrointestinal dysmotility occurs frequently in the critically ill. Although the causes underlying dysmotility are multifactorial, both pain and its treatment with exogenous opioids are likely causative factors. The purpose of this review is to describe the effects of pain and opioids on gastrointestinal motility; outline the rationale for and evidence supporting the administration of opioid antagonists to improve dysmotility; and describe the potential influence opioids drugs have on the intestinal microbiome and infectious complications. RECENT FINDINGS: Opioid drugs are frequently prescribed in the critically ill to alleviate pain. In health, opioids cause gastric dysmotility, yet the evidence for this in critical illness is inconsistent and limited to observational studies. Administration of opioid antagonists may improve gastrointestinal motility, but data are sparse, and these agents cannot be recommended outside of clinical trials. Although critical illness is associated with alterations in the microbiome, the extent to which opioid administration influences these changes, and the subsequent development of infection, remains uncertain. SUMMARY: Replication of clinical studies from ambulant populations in critical care is required to ascertain the independent influence of opioid administration on gastrointestinal motility and infectious complications. PMID- 29461262 TI - Genetics of atrial fibrillation: an update. AB - PURPOSE OF REVIEW: Atrial fibrillation is a common cardiac arrhythmia with a high morbidity and mortality affecting 34 million worldwide. Current therapies are inadequate and often fail to directly address molecular mechanisms of the disease. In this review, we will provide an overview of recent advances in our understanding of the genetic underpinnings of atrial fibrillation. RECENT FINDINGS: Large-scale genetic association studies have more than doubled the number of genetic loci associated with atrial fibrillation during the last year. Studies examining how genes at or near these loci can affect the pathogenesis of atrial fibrillation are ongoing in cellular, animal, and computational models. In addition, several recent clinical studies have also demonstrated that variants at these loci can aid in risk stratification of patients. SUMMARY: There are now over 30 genetic loci associated with atrial fibrillation. A better understanding of how these loci relate to disease pathogenesis may provide insight into novel therapeutic targets and ultimately lead to improved clinical care. PMID- 29461263 TI - The role of feedback in ameliorating burnout. AB - PURPOSE OF REVIEW: Assessment of the current literature surrounding interventions directed toward the prevention of burnout in the field of medicine and particularly in anesthesiology. RECENT FINDINGS: Recently, burnout has been noted to lead to medication errors and subsequently increased harm to our patients. On a personal level, burnout can lead to depression and even suicide amongst physicians. Strategies to prevent burnout amongst anesthesiologists that have been studied in the literature include multisource feedback, mentorship and early recognition. SUMMARY: There remains no clear or definitive intervention to prevent burnout for physicians. However, changing our environment to embrace mentorship, the continual exchange of feedback and the fostering self-care could startlingly improve our work environment. PMID- 29461264 TI - Human milk composition and infant growth. AB - PURPOSE OF REVIEW: This review highlights relevant studies published between 2015 and 2017 on human milk composition and the association with infant growth. RECENT FINDINGS: High-quality studies investigating how human milk composition is related to infant growth are sparse. Recent observational studies show that human milk concentrations of protein, fat, and carbohydrate likely have important influence on infant growth and body composition. Furthermore, some observational studies examining human milk oligosaccharides and hormone concentrations suggest functional relevance to infant growth. For human milk micronutrient concentrations and microbiota content, and other bioactive components in human milk, the association with infant growth is still speculative and needs further investigation. The included studies in this review are all limited in their methodological design and methods but have interesting potential in understanding infant growth. SUMMARY: Available evidence on human milk composition in relation to infant growth is sparse. This review summarizes recent publications investigating human milk composition; including micro- and macronutrients, human milk oligosaccharides, hormones and other bioactive components, and the association with infant weight, length, body mass index, and body composition. PMID- 29461265 TI - Severe acute malnutrition. AB - PURPOSE OF REVIEW: Advances in our understanding of the treatment of severe acute malnutrition (SAM) in a resource-limited environment are needed to improve outcome. RECENT FINDINGS: Ready-to-use therapeutic foods (RUTFs) made from local products and with reduced milk content lower costs and may be effective in older children. None of the therapeutic foods used to treat severely malnourished children correct long chain polyunsaturated fatty acid deficiencies.Routine short term antibiotic (amoxicillin) treatment, in the context of adequate healthcare supervision, does not improve the recovery rate. Long-term antibiotic (cotrimoxazole) treatment also does not provide significant benefit to non-HIV infected children.Increased pathogenic bacteria have been found in the intestinal microbiome of malnourished children and candidate organisms for use as probiotics have been identified. There is, however, no evidence to support the routine use of probiotics in these children. Although exocrine pancreatic function is reduced in malnourished children, routine pancreatic enzyme supplementation does not lead to accelerated recovery. SUMMARY: Alternative RUTF may provide a cheaper and more acceptable alternative to standard RUTF in the near future. Further research is needed to understand the implications of fatty acid deficiencies and dysbiosis that occur in malnourished children. Routine antibiotic administration in the appropriate setting is unnecessary. PMID- 29461266 TI - Use of Pocket-Sized Ultrasound Device in the Diagnosis of Shoulder Pathology. AB - OBJECTIVE: Musculoskeletal ultrasound imaging is increasingly being used for static and dynamic imaging of tendons, muscles, ligaments, and bones. New, hand held, pocket-sized ultrasounds are more portable and affordable. The purpose of this study was to evaluate the feasibility of pocket-sized ultrasound to diagnose shoulder pathology. DESIGN: Prospective cohort study. SETTING: Tertiary Care Hospital. METHODS: Ten consecutive patients (mean age 54; range 42-68 years) referred for a shoulder ultrasound for evaluation of shoulder pain were recruited. A diagnostic ultrasound was performed first with a pocket-sized ultrasound machine (VScan; General Electric, Northville, MI) and cine images saved for later review. Next, standard diagnostic ultrasound by a radiology technician specialized in musculoskeletal ultrasound was performed using (LOGIQ; General Electric, Northville, MI) ultrasound. The radiology report from the standard diagnostic ultrasound was used as the gold standard for diagnoses. Two independent evaluators, a musculoskeletal-trained radiologist and a sports medicine-trained physician with over 8 years of experience with musculoskeletal ultrasound, reviewed the images from the pocket-sized ultrasound. RESULTS: Nine of the studies were diagnosed with a pathologic entity during the standard diagnostic ultrasound and 1 was found to be normal. Diagnoses ranged from biceps tendinopathy, calcific tendonitis, and partial-articular-sided rotator cuff tear. Evaluator 1 correctly identified 7/10 diagnoses and evaluator 2 correctly identified 8/10 diagnoses. The evaluators also rated their confidence in diagnosis as 4.2/5 and the image quality as 3.7/4 from the pocket-sized ultrasound. DISCUSSION: The findings from this study demonstrate that pocket sized, hand-held ultrasound machines may be used to identify shoulder pathology. PMID- 29461267 TI - A Prospective Transcranial Doppler Ultrasound-Based Evaluation of the Effects of Repetitive Subconcussive Head Trauma on Neurovascular Coupling Dynamics. AB - OBJECTIVE: To determine the effects of repetitive subconcussive head trauma on neurovascular coupling (NVC) responses. DESIGN: Prospective cohort study collected between September 2013 and December 2016. SETTING: University laboratory. PARTICIPANTS: One hundred seventy-nine elite, junior-level (age, 19.6 +/- 1.5 years) contact sport (ice hockey, American football) athletes recruited for preseason testing. Fifty-two nonconcussed athletes returned for postseason testing. Fifteen noncontact sport athletes (age, 20.4 +/- 2.2 years) also completed preseason and postseason testing. EXPOSURE(S): Subconcussive sport related head trauma. MAIN OUTCOME MEASURES: Dynamics of NVC were estimated during cycles of 20 seconds eyes closed and 40 seconds eyes open to a visual stimulus (reading) by measuring cerebral blood flow (CBF) velocity in the posterior (PCA) and middle (MCA) cerebral arteries via transcranial Doppler ultrasound. RESULTS: Both athlete groups demonstrated no significant differences in PCA or MCA NVC dynamics between preseason and postseason, despite exposure to a median of 353.5 (range, 295.0-587.3) head impacts (>2g) over the course of the season for contact sport athletes. CONCLUSIONS: Within the context of growing concern over detrimental effects of repetitive subconcussive trauma, the current results encouragingly suggest that the dynamics of NVC responses are not affected by 1 season of participation in junior-level ice hockey or American football. This is an important finding because it indicates an appropriate postseason CBF response to elevated metabolic demand with increases in neural activity. PMID- 29461268 TI - Unnatural Deaths of the Elderly Population of Sri Lanka: A Descriptive Analysis. AB - As people age, they may become more vulnerable to injury because of frailty, ill health, or dependency on others. Data from medicolegal death investigation including autopsy and statements from cases reported to 3 medicolegal units in Sri Lanka were analyzed in this study under the strict ethical framework. Of the study population, 265 were male and 75 were female. Mean age was 71.14 years. Commonest manner of death was accidental (62.1%) followed by suicide (32.1%) and homicide (5.6%). Commonest types of incidents were road traffic accidents (26.5%), falls (22.6%), and poisoning (21.2%). Among the road traffic accidents, pedestrians (77.9%) were the majority. Poisoning (59.6%) was the commonest method of suicide. The commonest weapons used in homicides were blunt weapons (47.3%). Association with alcohol was seen in more than 10% of suicidal and accidental deaths. More attention should be given to the elderly people who are using the roads while developing policies by the state. Furthermore, it is high time to think about psychological aspect in the elderly care management specially alcohol abuse and suicidal ideation among them. PMID- 29461269 TI - Coronary Artery Abnormalities as the Cause of Sudden Cardiac Death: A 20-Year Review. AB - In this case series, we delve into the database of medicolegal cases of the Forensic Pathology Department at Hamilton Health Sciences in Hamilton Ontario from the last 20 years (1996-2017), and review cases of sudden cardiac death due to coronary artery abnormalities. We found 17 cases that fit the criteria, which gave us an incidence of 1.34 per 1000 cases. These cases were further audited for age, sex, type of coronary artery abnormality, symptoms before demise, circumstances of death, presence of significant atherosclerotic disease, and toxicology. Two more recent cases underwent postmortem genetic testing, and we reported on the result of one of these molecular studies. In our case series, the most commonly affected coronary artery was the right coronary artery, with the most common anomaly being abnormal origin from the left sinus of Valsalva. Although the literature maintains that left coronary artery from the opposite sinus is associated with higher incidence of SCD, our study shows that RCAs from the opposite aortic sinus, including those deemed to be low risk by classification, can be causes of SCD. PMID- 29461270 TI - The Role of Personality in a Regular Cognitive Monitoring Program. AB - OBJECTIVES: This study examines the role of personality in cognitive performance, adherence, and satisfaction with regular cognitive self-monitoring. MATERIALS AND METHODS: One hundred fifty-seven cognitively healthy older adults, age 55+, completed the 44-item Big-Five Inventory and were subsequently engaged in online monthly cognitive monitoring using the Cogstate Brief Battery for up to 35 months (M=14 mo, SD=7 mo). The test measures speed and accuracy in reaction time, visual learning, and working memory tasks. RESULTS: Neuroticism, although not related to cognitive performance overall (P>0.05), was related to a greater increase in accuracy (estimate=0.07, P=0.04) and speed (estimate=-0.09, P=0.03) on One Card Learning. Greater conscientiousness was related to faster overall speed on Detection (estimate=-1.62, P=0.02) and a significant rate of improvement in speed on One Card Learning (estimate=-0.10, P<0.03). No differences in satisfaction or adherence to monthly monitoring as a function of neuroticism or conscientiousness were observed. CONCLUSIONS: Participants volunteering for regular cognitive monitoring may be quite uniform in terms of personality traits, with personality traits playing a relatively minor role in adherence and satisfaction. The more neurotic may exhibit better accuracy and improve in speed with time, whereas the more conscientious may perform faster overall and improve in speed on some tasks, but the effects appear small. PMID- 29461271 TI - Endothelin Signaling Contributes to Modulation of Nociception in Early-stage Tongue Cancer in Rats. AB - BACKGROUND: Patients with early stage tongue cancer do not frequently complain of tongue pain. Endothelin-1 signaling is upregulated in the cancerous tongue at the early stage. We tested the hypothesis that endothelin-1 signaling contributes to the modulation of tongue nociception. METHODS: Squamous cell carcinoma cells were inoculated into the tongue under general anesthesia. Lingual mechanical sensitivity under light anesthesia using forceps from days 1 to 21 (n = 8) and the amounts of endothelin-1 and beta-endorphin in the tongue on days 6, 14, and 21 (n = 5 to 7) were examined after the inoculation. The effect of endothelin-A or u-opioid receptor antagonism on the mechanical sensitivity was examined (n = 5 to 7). RESULTS: Lingual mechanical sensitivity did not change at the early stage (days 5 to 6) but increased at the late stage (days 13 to 14). The amount of endothelin-1 increased (25.4 +/- 4.8 pg/ml vs. 15.0 +/- 5.2 pg/ml; P = 0.008), and endothelin-A receptor antagonism in the tongue induced mechanical hypersensitivity at the early stage (51 +/- 9 g vs. 81 +/- 6 g; P = 0.0001). The u-opioid receptor antagonism enhanced mechanical hypersensitivity (39 +/- 7 g vs. 81 +/- 6 g; P < 0.0001), and the amount of beta-endorphin increased at the early stage. CONCLUSIONS: beta-Endorphin released from the cancer cells via endothelin 1 signaling is involved in analgesic action in mechanical hypersensitivity at the early stage. PMID- 29461272 TI - Does Aerobic Respiration Produce Carbon Dioxide or Hydrogen Ion and Bicarbonate? AB - Maintenance of intracellular pH is critical for clinical homeostasis. The metabolism of glucose, fatty acids, and amino acids yielding the generation of adenosine triphosphate in the mitochondria is accompanied by the production of acid in the Krebs cycle. Both the nature of this acidosis and the mechanism of its disposal have been argued by two investigators with a long-abiding interest in acid-base physiology. They offer different interpretations and views of the molecular mechanism of this intracellular pH regulation during normal metabolism. Dr. John Severinghaus has posited that hydrogen ion and bicarbonate are the direct end products in the Krebs cycle. In the late 1960s, he showed in brain and brain homogenate experiments that acetazolamide, a carbonic anhydrase inhibitor, reduces intracellular pH. This led him to conclude that hydrogen ion and bicarbonate are the end products, and the role of intracellular carbonic anhydrase is to rapidly generate diffusible carbon dioxide to minimize acidosis. Dr. Erik Swenson posits that carbon dioxide is a direct end product in the Krebs cycle, a more widely accepted view, and that acetazolamide prevents rapid intracellular bicarbonate formation, which can then codiffuse with carbon dioxide to the cell surface and there be reconverted for exit from the cell. Loss of this "facilitated diffusion of carbon dioxide" leads to intracellular acidosis as the still appreciable uncatalyzed rate of carbon dioxide hydration generates more protons. This review summarizes the available evidence and determines that resolution of this question will require more sophisticated measurements of intracellular pH with faster temporal resolution. PMID- 29461273 TI - Relationship of surgeon/hospital volume with outcomes in uro-oncology surgery. AB - PURPOSE OF REVIEW: Hospital and surgical volumes, as well as complications, are considered to influence intra and postoperative results in most surgical operations. This trend is also seen in uro-oncologic surgery. The objective of this review is to critically analyze the most recent literature to give a comprehensive overview on whether surgical and hospital volumes have an impact, and whether regionalization of the procedure should be advised. RECENT FINDINGS: Uro-oncologic surgery has recently become more regionalized, and data coming from different population-based analyses appear to support this trend. Recent data suggest that the most beneficial procedures could be radical cystectomy, radical prostatectomy, and partial nephrectomy. For radical cystectomy, even considering different cut-off values, saw better results for postoperative complications, mortality and long-term oncological and functional outcomes in patients treated in high-volume institutions. Centralization of radical prostatectomy seems to affect short-term outcomes and costs related to prostate cancer treatment, with high-volume institutions providing more affordable treatments reducing cancer recurrence and progression. Partial nephrectomy is more frequently performed in cT1-b cancer in high-volume than low-volume institutions. Additionally, in this setting it has a higher success rate and lower complications, shorter operative time, and fewer prolonged hospital stays. SUMMARY: Regionalization of the procedure in high-volume centers seems to have impact on postoperative morbidity and mortality for the most frequent major uro-oncological procedures: radical prostatectomy, radical cystectomy, and partial nephrectomy; but there are insufficient data available on other procedures. PMID- 29461274 TI - Long-term results of intestinal transplantation in children: survival after 10 years, intestinal function, quality of life. AB - PURPOSE OF REVIEW: The review aims to describe in detail contemporary medical, nutritional, and psychosocial results in pediatric intestinal transplant (ITx) recipients greater than 10 years removed from their transplant, and to highlight significant long-term post-ITx challenges and complications. The review will draw from recent publications in the field, the ITx registry as well as detailed unpublished data from a large, well established single center. RECENT FINDINGS: The majority of long-term ITx survivors are off parenteral nutrition altogether, but a significant number require supplemental tube feeds to gain weight and grow properly. A number of micronutrient deficiencies are observed in long-term follow up. Renal insufficiency and posttransplant lymphoproliferative disorder are the most concerning long-term complications. Many require special education, and in certain domains some report lower health related quality of life. SUMMARY: For children more than 10 years out from ITx, growth and weight gain are sustained; oral aversion and dependence on supplemental tube feeds remain prevalent issues. Most recipients are successfully managed with frequent outpatient visits and multiple daily medications. Post-transplant lymphoproliferative disorder and chronic kidney disease are long-term concerns. Though many children require special education, most are high functioning and report good health-related quality of life. PMID- 29461275 TI - Management of the critically ill liver failure patient: surpassing our limitations to reach transplantation. AB - PURPOSE OF REVIEW: Patients with liver failure and liver-related diseases are often critically ill. Here, we review advances in donor organ management, tools for patient selection and highlight ICU management of liver transplant (LT) recipients. A focused discussion on the impact each of these factors have on critical care management of liver failure patients is presented. RECENT FINDINGS: Artificial liver assist devices to increase donor organ utilization are broadening the potential for transplantation of critically ill patients. Additionally, prognostication tools continue to improve and identify patients salvageable with transplantation despite severely deranged physiology. Most importantly, early recognition of liver failure combined with proactive critical care management reduces the incidence of failure-to-rescue and increases the likelihood of transplantation. SUMMARY: Liver transplantation is often the only hope for cure, and despite the presence of profound physiologic disturbances surgery remains the goal. In this review, we cover topics key in ICU management of LT recipients. A focused discussion on development of artificial liver assist devices to increase donor organs, prognostic scoring systems to define appropriate transplant recipients, critical care management of liver failure physiology, and bridging modalities and supportive measures are presented. PMID- 29461276 TI - Health surveillance for occupational asthma. AB - PURPOSE OF REVIEW: The outcome for workers with occupational asthma is improved for those with an earlier diagnosis. Health surveillance at work is in principle designed to identify such cases, so that the risks to the individual worker, and coworkers, can be reduced. There is recent evidence to suggest that the uptake and quality of such surveillance could be improved. This review has assessed current approaches to health surveillance for occupational asthma. RECENT FINDINGS: The article covers a review of the utility of questionnaires, lung function testing, immunological investigations, and other tests, including exhaled nitric oxide, sputum eosinophilia, and exhaled breath condensate specifically in the context of workplace-based health surveillance. SUMMARY: Questionnaires remain a key component of respiratory health surveillance, although maybe limited by both sensitivity and specificity for early occupational asthma. The role of lung function testing is debated, although is recommended for higher level health surveillance. Various examples of immunological testing in health surveillance are discussed, but more evidence is needed in many specific areas before more general recommendations can be made. Evidence is discussed in relation to the utility of newer approaches such as exhaled nitric oxide, sputum eosinophilia, and exhaled breath condensate. PMID- 29461278 TI - Home Inotropes in Patients Supported with Left Ventricular Assist Devices. AB - There is little data outlining the use of outpatient inotropic medications in patients with existing left ventricular assist devices (LVADs). This case series explores this patient population and seeks to define the indications, complications, and safety of dual support. A retrospective chart review was conducted for all patients on LVAD and then subsequently started on home inotropes post device implant. Eight patients met inclusion criteria. The indications for inotropes were right ventricular failure, aortic insufficiency with biventricular failure, LVAD thrombosis with contraindication to device exchange, and cannula malposition with elevated pulmonary vascular resistance. Mean duration of combined support was 273+/-170 days. Cardiac index improved from 1.96 +/- 0.24 to 2.31 +/-0.35L/min/m after inotropes (p = 0.02). There was no change in hospital admissions. The most common reason for readmission was heart failure symptoms, followed by bleeding. Five patients died during the study period, one underwent heart transplant, and two remain on inotropic support. Home inotropes may be indicated in selected CF-LVAD patients with refractory right ventricular failure or impaired LVAD function. Inotropes can improve hemodynamics and provide palliation of symptoms. However, long-term inotrope use does not reduce hospital readmissions and is associated with multiple complications related to the need for an indwelling intravenous line. PMID- 29461277 TI - Clinical Relevance of Histopathologic Analysis of HeartMate II Thrombi. AB - Left ventricular assist device (LVAD) thrombosis is a devastating complication that occurs in about 10% of patients despite anticoagulation and antiplatelet treatment. How the thrombus initiates and propagates is unknown. We pathologically and immunohistochemically examined 28 thrombi removed from 17 HeartMate II LVADs. Two groups of thrombi were found: those formed in the inlet/outlet and those on the rotor. The four thrombi found at the inlet (three inlet conduit and one inlet tube) and outlet (three at outlet elbow and one outlet graft) appeared similar and were composed of a loose meshwork of fibrin(ogen), von Willebrand factor, leukocytes, and aggregated platelets. The majority of the thrombi (20/28), however, were located on the rotor: nine at the inlet bearing, five on the rotor vanes, and six at the outlet bearing. Laminated thrombi formed around the inlet bearing in rings, an area of blood recirculation. The inner rings of the thrombus had fibrin and von Willebrand factor. Aggregated platelets were found in the outer thrombi rings, but limited evidence of platelets within the laminated thrombi was noted. The presence of distinct rings suggests development of the clot over time. The increased platelets in the outer rings of the inlet bearing thrombi would support further investigation into their role in thrombus growth. Initiating events require further investigation, but the fibrin-rich structure of HeartMate II thrombi suggests that alternative anticoagulation strategies are needed to prevent thrombosis in our LVAD patients. PMID- 29461279 TI - Individualized Antithrombotic Therapy in Heartware HVAD Recipients. AB - There are no evidence-based guidelines for antithrombotic therapy in left ventricular assist device patients. We evaluated the efficacy of a multi-agent, test-guided protocol, which remained consistent throughout our use of the Heartware HVAD. Thrombelastography and PFA-100 guide antiplatelet titration. Goals are normal kaolin thrombelastography maximum amplitude and prolonged PFA 100. We analyzed incidence and rates of nonprocedural bleeding, stroke, and pump thrombosis for all 81 primary Heartware left ventricular assist devices implanted since 2011. For each event, we examined whether each test was within goal range. We also compared medication burden and dosage between patients with and without events. Pump thrombosis and hemorrhagic stroke each occurred in two patients (2.7%; 0.03 events/patient-year [EPPY]), and ischemic stroke in six (7.4%; 0.10 EPPY). Nonprocedural bleeding occurred 75 times in 34 patients (42%; 1.24 EPPY), primarily gastrointestinal (28%; 0.66 EPPY). Subtherapeutic INR was the most common at thrombotic events; supratherapeutic partial thromboplastin time, INR, and PFA-ADP were common at bleeding events. Medication burden and dosage were lower in patients with events than in stable patients. Protocol-guided antithrombotic therapy resulted in low rates of pump thrombosis and hemorrhagic stroke. Ischemic stroke and gastrointestinal bleeding rates were higher than in a comparable HVAD population. Optimization of our protocol to decrease its complexity and to reduce bleeding is underway. PMID- 29461280 TI - The rationale for a role for diet and nutrition in the prevention and treatment of cancer. AB - There is considerable evidence to support dietary recommendations for prevention of cancer as well as for patients undergoing or recovering from cancer treatment. We consider here implications from human, animal and in-vitro studies of the effects of dietary factors (macronutrients and micronutrients-phytochemicals) on cancer. An important epidemiology study, the China Project found a significant correlation between disease incidence and markers of animal product consumption. Evidence of the role of animal protein in the promotion of cancer also comes from animal studies. Food restriction has been shown in human and animal studies to slow cancer progression. Phytochemicals from whole plant foods are protective against oxidative stress, inhibit cell proliferation, induce cell-cycle arrest, and apoptosis, act as antiangiogenesis factors, and inhibit cyclooxygenase-2, which has been related to metastasis. Some mechanisms that mediate the effect of diet on cancer involve cell signaling through insulin factors and mammalian target of rapamycin, a nutrient sensing complex related to growth, altered gene expression through epigenetics, and the effects of microbial metabolites produced by the gut microbiota that is strongly influenced by dietary factors. The evidence accumulating for many years indicates that diet, what we eat every day, can affect disease. Besides preventing the development of cancer, this could also be harnessed to positively influence treatment outcomes as well as prevent recurrence. As research strategies developed for drug studies are not appropriate, it is important that new methodologies be developed to study these effects. PMID- 29461281 TI - Self-assessment of Goal Achievements Within a Gynecological Cancer Rehabilitation Counseling. AB - BACKGROUND: There is an increasing focus on patient involvement in cancer rehabilitation. Goal assessment may improve the patient's self-management of life after cancer. OBJECTIVE: The aim of this study was to evaluate whether (1) nurse led supported goal setting and assessment of goal achievement were feasible in a clinical setting and (2) there was a positive association between women's goal achievement and their self-assessed global health status (GHS). METHODS: Women surgically treated for gynecological cancer were offered rehabilitation counseling consisting of 2 face-to-face sessions and 2 phone calls carried out by a nurse. The Goal Attainment Scale evaluated goal achievement, whereas GHS was assessed with a quality-of-life questionnaire (European Organization of Research and Treatment of Cancer Quality of Life Questionnaire Core 30). RESULTS: One hundred fifty-one women consented to participate; 70% of the women at the first phone call and 72% at the second phone call achieved their goals as "expected" or "more or much more than expected." Endometrial cancer patients more often achieved their goals than ovarian or cervical cancer patients. Approximately 32% of ovarian and 40% of cervical cancer patients scored their goal achievement "below expected." The patients' GHS was not associated with goal attainment measured at each phone call. CONCLUSION: Goal measurement is feasible in cancer rehabilitation, in both goal setting and goal achievement. Goal achievement less than expected levels in women recovering from ovarian or cervical cancer suggests a need for additional support. IMPLICATIONS FOR PRACTICE: This study supports goal setting and goal achievement as a feasible approach to improve cancer rehabilitation and that nursing professionals can facilitate individualized rehabilitation efforts. PMID- 29461282 TI - A Behavioral Physical Activity Intervention to Manage Moderate and Severe Fatigue Among Head and Neck Cancer Patients-Pre-efficacy Study in the National Institutes of Health ORBIT Model. AB - BACKGROUND: Cancer-related fatigue (CRF) reduces head and neck cancer (HNC) survival rates and is the most common, severe, and distressing symptom negatively impacting activities of daily living (ADLs) dependence among HNC patients. These patients remain physically inactive after their cancer treatment, although there is consensus that physical activity mitigates CRF in cancer patients. OBJECTIVE: A home-based personalized behavioral physical activity intervention with fitness graded motion exergames (PAfitME) was evaluated for its intervention components, intervention delivery mode, and intervention contact time/duration with initial assessment of the feasibility, acceptability, safety, and outcomes. METHODS: This study (N = 8) was a single-group, pre-post design to evaluate a 6-week PAfitME at the end of HNC treatment. Health outcomes were CRF, ADL dependence, and fitness performance. Behavioral outcomes were exergame adherence. RESULTS: Positive health and behavioral outcomes support the PAfitME protocol including intervention components, intervention delivery mode, and intervention contact times/duration. The PAfitME intervention is feasible and acceptable with promising adherence rates. No adverse events were reported. There was marked improvement in CRF, ADL dependence, cardiorespiratory fitness, balance, muscle strength, and shoulder forward flexion, with large to moderate effect sizes as a result of the PAfitME intervention. CONCLUSION: The PAfitME protocol is ready for additional testing in a randomized clinical trial. IMPLICATIONS FOR PRACTICE: The PAfitME intervention is a nurse-led nonpharmacological intervention. It can be integrated into home care or telehealth care for HNC patients at the end of their cancer treatment once effectiveness is established. PMID- 29461283 TI - The Impact of Education About Cervical Cancer and Human Papillomavirus on Women's Healthy Lifestyle Behaviors and Beliefs: Using the PRECEDE Educational Model. AB - BACKGROUND: Early detection of cervical cancer improves the chances of successful treatment. OBJECTIVE: The aim of this study was to determine the effect of education about cervical cancer and human papillomavirus on the healthy lifestyle, behavior, and beliefs of Turkish women who were without cancer, using the PRECEDE education model. METHODS: This qualitative and quantitative study was conducted as a prospective, randomized, 2-group (intervention and control) trial at a community training center in north Turkey. A total of 156 Turkish women who were without cancer participated in this study. The semistructured interview form, the SF-36 Health Status Questionnaire, the Health Belief Model Scale for Cervical Cancer and Pap Smear Test, and the Healthy Lifestyle Behavior Scale II were used. RESULTS: The subdimension scores of the Health Belief Model Scale for Cervical Cancer and Pap Smear Test were found to be higher among women in the study group (cervical cancer seriousness, P = .001; health motivation, P = .001) as compared with the control group after the education program. The SF-36 Health Status Questionnaire domain scores for physical role limitations, mental role limitations, and general health perceptions increased in the study group after the intervention. CONCLUSION: The posteducation health motivation of women in the study group was improved, the women's perceptions of obstacles to Papanicolaou testing decreased, and through increased knowledge and awareness, the rate of Papanicolaou testing increased. IMPLICATIONS FOR PRACTICE: Educational programs aimed at motivating women to increase their awareness of cervical cancer, preventing cervical cancer, and having Papanicolaou testing are necessary and beneficial in this sample. PMID- 29461284 TI - Psychometric Performance of the Arabic Versions of the Cancer Behavior Inventory Brief and the Functional Assessment of Cancer Therapy-Breast. AB - BACKGROUND: Valid and reliable instruments in Arabic are needed to measure self efficacy and quality of life for Arabic patients with cancer. OBJECTIVE: The aim of this study was to test the psychometric performance of the Cancer Behavior Inventory-Brief Arabic (CBI-BA), including participant understanding of items, and the Functional Assessment of Cancer Therapy-Breast Arabic (FACT-BA). METHODS: Using a cross-sectional design, 438 cancer patients completed the CBI-BA, 30 of whom completed cognitive interviews. A subsample 167 women with breast cancer also completed the FACT-BA. Internal consistency evidence was assessed with Cronbach's alpha and construct validity with principal axis factoring. RESULTS: Internal consistency estimates were acceptable for the total CBI-BA (alpha = .81) and FACT-BA (alpha = .88) scales. Exploratory factor analyses showed evidence of construct validity for the CBI-BA; 1 factor was derived, compared with four in the original English version. Cognitive interviews indicated satisfactory patient understanding of CBI-BA items. The Arabic version of the general FACT-General scale had 4 factors according to expectation. CONCLUSION: The CBI-BA has adequate psychometric performance for the measurement of self-efficacy for coping with cancer in Arabic patients. The FACT-General Arabic has adequate evidence of reliability and validity for the measurement of quality of life in Arabic women with breast cancer. IMPLICATIONS FOR PRACTICE: The availability of culturally sensitive and psychometrically sound instruments for Arabic patients diagnosed with cancer should be valuable for healthcare clinicians and researchers to assess self-efficacy for coping with cancer and quality of life. PMID- 29461285 TI - Gauging the Effects of Self-efficacy, Social Support, and Coping Style on Self management Behaviors in Chinese Cancer Survivors. AB - BACKGROUND: Better self-management control in cancer survivors would benefit their functional status, quality of life, and health service utilization. Factors such as self-efficacy, social support, and coping style are important predictors of self-management behaviors of cancer survivors; however, the impact of these factors on self-management behaviors has not yet been empirically tested in Chinese cancer survivors. OBJECTIVES: The aim of this study was to examine how self-efficacy, social support, and coping style affect specific self-management behaviors. METHODS: A secondary data analysis was completed from a cross sectional study. A total of 764 cancer survivors were recruited in the study. Validated instruments were used to assess patients' self-efficacy, social support, and coping style. Structural equation modeling (SEM) was used to test the hypothesis. RESULTS: The SEM model fits the data very well, with root mean square error of approximation (RMSEA) of 0.034; close-fit test cannot reject the hypothesis of root mean square error of approximation of 0.05 or less, comparative fit index of 0.91, Tucker-Lewis index of 0.90, and weighted root mean square residual of 0.82. For the measurement models in the SEM, all items loaded highly on their underlying first-order factors, and the first-order factors loaded highly on their underlying second-order factors (self-efficacy and social support, respectively). The model demonstrated that self-efficacy and social support directly and indirectly, via coping style, affect 3 self-management behaviors (ie, communication, exercise, and information seeking). CONCLUSION: Our results provide evidence that self-efficacy and social support impose significant direct effects, as well as indirect effects via copying style, on the self management of cancer survivors. IMPLICATIONS FOR PRACTICE: Our findings may help nurses to further improve their care of cancer survivors in terms of their self management behaviors, specifically communication, exercise, and information seeking. PMID- 29461286 TI - Recent advances in the treatment of rheumatoid arthritis. AB - PURPOSE OF REVIEW: Therapies for rheumatoid arthritis (RA) continue to expand rapidly. The purpose of this review is to discuss novel treatment options, including biosimilars, that are available, as well as to highlight promising agents in development. The purpose is also to discuss new emerging safety signals associated with these drugs and to discuss strategies in tapering therapy. RECENT FINDINGS: There are several novel RA therapies. These include the interleukin-6 (IL-6) receptor blocker sarilumab, which was approved in 2017. In aggregate, the sarilumab studies show that it is effective in RA, including patients with incomplete responses to methotrexate and anti-tumor necrosis factor inhibitor, and showing superior efficacy when used in higher dose (200 mg every 2 weeks) to standard-dose adalilumab. Other drugs that are currently being studied include the IL-6 cytokine blocker sarikumab, the small targeted molecule filgotinib, and many new biosimilars. Baracitinib failed to achieve approval by the Food and Drug Administration primarily over perceived safety concerns. The two biosimilar drugs currently approved are CT-P13 and SB2, which are based on the reference product infliximab. Although this review summarizes trials examining biologic tapering, additional data are needed to guide clinicians in regards to treatment de escalation in RA. SUMMARY: With the greatly expanded armamentarium of RA treatment options available, it is important for clinicians to understand the data regarding drug efficacy and safety. With remission increasingly attainable, effective drug tapering strategies are needed. Although tapering trials do exist, more studies will be needed to help guide clinical practice. PMID- 29461287 TI - Developing competent videofluoroscopic swallowing study analysts. AB - PURPOSE OF REVIEW: This review examines the recent literature concerning the development of VFSS analysts. RECENT FINDINGS: Face-to-face and blended methods of training improve reliability and accuracy of VFSS analysis. However, with the exception of the literature describing the MBSImP training, most studies investigate relatively brief training for specific VFSS rating tools. The influence of training mode and trainee factors has received limited attention. SUMMARY: There is a lack of controlled studies investigating the influences of training methods for VFSS analysis. Pilot data is emerging concerning VFSS analysis training 'packages' but without information about the relative influence of training mode, it is difficult to determine the most efficient and cost effective way of training VFSS analysts. Future research should investigate the contribution of trainee-related factors to succeed in VFSS analysis training, and the relative benefits and disadvantages of online, peer, independent, and blended modes of training. PMID- 29461289 TI - Evolution of a Burn Care Network. AB - INTRODUCTION: A private burn center started in Augusta, GA, in 1978 has expanded into a burn care network of 7 comprehensive burn centers. We have analyzed 2 years of admissions to this network to assess growth and the network's level of participation in national burn care. MATERIALS AND METHODS: Total admissions to the network were quantified for years 2015 and 2016. Growth during that 2-year period was calculated, and the network's admissions were evaluated as a percentage of national burn admissions. RESULTS: Total admission for 2015 came from 4713 patients; 5683 patients were admitted in 2016. These totals demonstrated a 15% increase. The 2-year total of 10,217 admissions represented 21% of the 46,892 burn admissions in the United States for that period. CONCLUSIONS: This network has achieved a large capacity for burn admission and currently accounts for 21% of US burn admissions. The network has capacity for continued growth and the development of clinical innovations and research. PMID- 29461288 TI - Carbon Monoxide and Cyanide Poisoning in the Burned Pregnant Patient: An Indication for Hyperbaric Oxygen Therapy. AB - Carbon monoxide (CO) is a small molecule poison released as a product of incomplete combustion. Carbon monoxide binds hemoglobin, reducing oxygen delivery. This effect is exacerbated in the burned pregnant patient by fetal hemoglobin that binds CO 2.5- to 3-fold stronger than maternal hemoglobin. With no signature clinical symptom, diagnosis depends on patient injury history, elevated carboxyhemoglobin levels, and alterations in mental status. The standard of care for treatment of CO intoxication is 100% normobaric oxygen, which decreases the half-life of CO in the bloodstream from 5 hours to 1 hour. Hyperbaric oxygen (HBO2) is a useful adjunct to rapidly reduce the half-life of CO to 20 minutes and the incidence of delayed neurologic sequelae. Because of the slow disassociation of CO from hemoglobin in the fetus, there is a far stronger indication for HBO2 in the burned pregnant patient than in other burn patient populations.Cyanide intoxication is often a comorbid disease with CO in inhalation injury from an enclosed fire, but may be the predominant toxin. It acts synergistically with CO to effectively lower the lethal doses of both cyanide and CO. Diagnosis is best made in the presence of high lactate levels, carboxyhemoglobin concentrations greater than 10%, injury history of smoke inhalation from an enclosed fire, and alterations in consciousness. While treatment with hydroxocobalamin is the standard of care and has the effect of reducing concomitant CO toxicity, data indicate cyanide may also be displaced by HBO2.Carbon monoxide and cyanide poisoning presents potential complications impacting care. This review addresses the mechanism of action, presentation, diagnosis, and treatment of CO and cyanide poisonings in the burned pregnant patient and the use of HBO2 therapy. PMID- 29461290 TI - Volume Resuscitation in Patients With High-Voltage Electrical Injuries. AB - Volume resuscitation of patients with high-voltage electrical injuries (>1000 V) is a more complex challenge than standard burn resuscitation. High voltages penetrate deep tissues. These deep injuries are not accounted for in resuscitation formulae dependent on percentage of cutaneous burn. Myonecrosis occurring from direct electrical injury and secondary compartment syndromes can result in rhabdomyolysis, compromising renal function and urine output. Urine output is the primary end point, with a goal of 1 mL/kg/h for adult patients with high-voltage electrical injuries. As such, secondary resuscitation end points of laboratory values, such as lactate, base deficit, hemoglobin, and creatinine, as well as hemodynamic monitoring, such as mean arterial pressure and thermodilution techniques, can become crucial in guiding optimum administration of resuscitation fluids. Mannitol and bicarbonates are available but have limited support in the literature. High-voltage electrical injury patients often develop acute kidney injury requiring dialysis and have increased risks of chronic kidney disease and mortality. Continuous venovenous hemofiltration is a well-supported adjunct to clear the myoglobin load that hemodialysis cannot from circulation. PMID- 29461291 TI - Fifty Years of Burn Care at Shriners Hospitals for Children, Galveston. AB - More than 50 years ago, Shriners Hospitals for Children expanded their philanthropy to include care for burned children. In so doing, the effects of their work weightily expanded from rehabilitation and quality of life outcomes to include survival proper. As the first facility dedicated to the care of burned children, originally designated the Shriners Burn Institute, the Galveston hospital remains the cornerstone of this endeavor. Shriners maintains charitable pediatric hospitals, provide care irrespective of the patient's or the family's ability to pay, and promote research. The sole criterion for admission at Shriners Hospitals for Children is the determination by a surgeon at a Shriners hospital that "the child's trouble may be corrected or improved." This philanthropic effort to provide medical care for children is one expression of the human commonality recognized by Shriners. In this article, we provide some background information on how this hospital came into existence as well as a global summary of its interventions toward greater survival and more complete rehabilitation of burned children. Based on the findings presented herein, we assert that there is less suffering and less loss of life due to childhood burns today than in previous years. We attribute much of this improvement to the simple voluntary collective decision by Shriners to provide alms for burned children. PMID- 29461294 TI - Basic Microvascular Anastomosis Simulation Hub Microsurgery Course: An Innovative Competency-Based Approach to Microsurgical Training for Early Year's Plastic Surgery Trainees. AB - Early year's plastic surgery trainees are faced with a large choice of microsurgery courses to select from. In the context of dwindling study budgets and busy on-call rotas, the pressure to select a high yield course that delivers value for money is of paramount importance.The Basic Microvascular Anastomosis Simulation Hub Microsurgery Course is a GBP L600 (US $790) 5-day 40-hour course based at Barts and The London School of Medicine and Dentistry increasing in popularity among junior trainees to fit this brief. PMID- 29461293 TI - Labiaplasty: A 24-Month Experience in 58 Patients: Outcomes and Statistical Analysis. AB - BACKGROUND: Because there has been a great raise in the interest of this type of surgery in our area, we decided to study if there were any differences among our patients and also to review our results. OBJECTIVE: The purpose of this study was to review our experience with labiaplasty. We assessed surgical complications and quality outcomes and compared surgical results according to maternal parity. METHODS: We conducted a retrospective chart review of all cases of primary or secondary labia minora reduction surgery performed by the same surgeon from January 2014 to December 2015. We recorded patient demographics, sexual activity, parity, and presurgical and postsurgical quality of life, as well as surgical technique and complications. RESULTS: During the study period, we performed 58 labia minora reduction procedures. The average patient age was 32.16 years. Among the patients, 50% were single, 65.52% sexually active, and 62.07% nulliparous. A wedge excision was performed in 75.8% of cases. A complication occurred in 12.06% of cases, usually owing to underresection. The surgical experience was rated very good or excellent by 96.55% of patients. Women with children reported greater satisfaction with their surgical outcome on our postoperative questionnaire. We identified no statistically significant outcome differences according to surgical technique. CONCLUSIONS: Labiaplasty is safe and shows high rates of overall satisfaction. Women with children reported greater postoperative satisfaction than women who had never given birth. PMID- 29461292 TI - Inhalation Injury in the Burned Patient. AB - Inhalation injury causes a heterogeneous cascade of insults that increase morbidity and mortality among the burn population. Despite major advancements in burn care for the past several decades, there remains a significant burden of disease attributable to inhalation injury. For this reason, effort has been devoted to finding new therapeutic approaches to improve outcomes for patients who sustain inhalation injuries.The three major injury classes are the following: supraglottic, subglottic, and systemic. Treatment options for these three subtypes differ based on the pathophysiologic changes that each one elicits.Currently, no consensus exists for diagnosis or grading of the injury, and there are large variations in treatment worldwide, ranging from observation and conservative management to advanced therapies with nebulization of different pharmacologic agents.The main pathophysiologic change after a subglottic inhalation injury is an increase in the bronchial blood flow. An induced mucosal hyperemia leads to edema, increases mucus secretion and plasma transudation into the airways, disables the mucociliary escalator, and inactivates hypoxic vasocontriction. Collectively, these insults potentiate airway obstruction with casts formed from epithelial debris, fibrin clots, and inspissated mucus, resulting in impaired ventilation. Prompt bronchoscopic diagnosis and multimodal treatment improve outcomes. Despite the lack of globally accepted standard treatments, data exist to support the use of bronchoscopy and suctioning to remove debris, nebulized heparin for fibrin casts, nebulized N-acetylcysteine for mucus casts, and bronchodilators.Systemic effects of inhalation injury occur both indirectly from hypoxia or hypercapnia resulting from loss of pulmonary function and systemic effects of proinflammatory cytokines, as well as directly from metabolic poisons such as carbon monoxide and cyanide. Both present with nonspecific clinical symptoms including cardiovascular collapse. Carbon monoxide intoxication should be treated with oxygen and cyanide with hydroxocobalamin.Inhalation injury remains a great challenge for clinicians and an area of opportunity for scientists. Management of this concomitant injury lags behind other aspects of burn care. More clinical research is required to improve the outcome of inhalation injury.The goal of this review is to comprehensively summarize the diagnoses, treatment options, and current research. PMID- 29461295 TI - Labia Majora Augmentation Combined With Minimal Labia Minora Resection: A Safe and Global Approach to the External Female Genitalia. AB - BACKGROUND: All the labia minora reduction techniques fail to treat the other component of the abnormally increased labia minora to majora ratio: the labia majora atrophy. The purpose of this study is to describe a technique of female genitalia beautification, which combines labia majora augmentation and conservative labia minora reduction. METHODS: The hypertrophied labia minora were first treated by a conservative inferior wedge excision with a superior flap. The conservative excision was done to obtain labia minora that would still protrude beyond the labia majora because it will be masked by the augmentation of the labia majora. Labia majora augmentation was done by autologous fat transplantation. The newly augmented labia majora completely masked the conservatively reduced labia minora. RESULTS: Twenty-one patients underwent surgery for labia majora augmentation and labia minora reduction. One patient (4.7%) had a small separation of the labial edge postoperatively that resolved with no additional interventions. There was no flap necrosis or infections. No patient reported pain or sexual dysfunction. Seventeen patients (81%) were satisfied or very satisfied with their results. CONCLUSIONS: Labia majora augmentation combined with a conservative labia minora reduction is an appealing procedure because it enhances the global aspect of the female genitalia while reducing the labioplasty complications. PMID- 29461296 TI - Evidence supporting laparoscopic hernia repair in children. AB - PURPOSE OF REVIEW: Pediatric inguinal hernias are a commonly performed surgical procedure. Currently, they can be approached via open or laparoscopic surgery. We summarize the current evidence for laparoscopic inguinal hernia repairs in children. RECENT FINDINGS: Laparoscopic and open inguinal hernia repair in children are associated with similar operative times for unilateral hernia, as well as similar cosmesis, complication rates and recurrence rates. Bilateral hernia repair has been shown to be faster through a laparoscopic approach. The laparoscopic approach is associated with decreased pain scores and earlier recovery, although only in the initial postoperative period. Laparoscopy allows for easy evaluation of the patency of contralateral processus vaginalis, although the clinical significance of and need for repair of an identified defect is unclear. SUMMARY: Laparoscopic surgery for pediatric inguinal hernias offers some advantages over open repair with most outcomes being equal. It should be considered a safe alternative to open repair to children and their caregivers. PMID- 29461297 TI - Maternal fetal medicine: recent developments and moving forward. PMID- 29461298 TI - Adolescent Internet Use, Social Integration, and Depressive Symptoms: Analysis from a Longitudinal Cohort Survey. AB - OBJECTIVE: To examine the association between adolescent leisure-time Internet use and social integration in the school context and how this association affects later depressive symptoms among adolescents in Taiwan, using a large nationwide cohort study and the latent growth model (LGM) method. METHODS: Data of 3795 students followed from the year 2001 to 2006 in the Taiwan Education Panel Survey were analyzed. Leisure-time Internet use was defined by the hours per week spent on (1) online chatting and (2) online games. School social integration and depressive symptoms were self-reported. We first used an unconditional LGM to estimate the baseline (intercept) and growth (slope) of Internet use. Next, another LGM conditioned with school social integration and depression was conducted. RESULTS: Approximately 10% of the participants reported engaging in online chatting and/or gaming for more than 20 hours per week. Internet use for online chatting showed an increase over time. School social integration was associated with the baseline amount (coefficient = -0.62, p < 0.001) but not the growth of leisure-time Internet use. The trend of Internet use was positively related to depressive symptoms (coefficient = 0.31, p < 0.05) at Wave 4. CONCLUSION: School social integration was initially associated with decreased leisure-time Internet use among adolescents. The growth of Internet use with time was not explainable by school social integration but had adverse impacts on depression. Reinforcing adolescents' bonding to school may prevent initial leisure-time Internet use. When advising on adolescent Internet use, health care providers should consider their patients' social networks and mental well-being. PMID- 29461299 TI - Reliability of Blotting Techniques to Assess Contact Lens Water Content. AB - OBJECTIVES: To determine the reliability of wet and modified dry blotting techniques used in the gravimetric method to assess contact lens (CL) water content (WC), the accuracy of both techniques in comparison with the nominal WC, and also their agreement. METHODS: We evaluated hydrated and dry CL mass values and WC using the gravimetric method in 440 daily disposable CLs. Samples assessed corresponded to Dailies Total 1, Dailies AquaComfort Plus, 1-Day Acuvue TruEye, and Biotrue ONEday. Back vertex power ranged from +3.00 diopters (D) to -6.00 D. Within-subject coefficient of variation (CVw) and intraclass correlation coefficients were calculated. Bland-Altman analysis was also performed. RESULTS: The modified dry blotting technique yielded significantly (P<=0.0001) higher hydrated CL mass values. The wet blotting technique provided significantly (P<=0.04) better consistency than the modified dry one. Values of CVw for wet and modified dry blotting techniques ranged from 1.2% to 2.1% and from 3.7% to 5.4%, respectively. As for dry CL mass values, CVw values were not significantly different (P>=0.05) between wet (range: 1.1%-1.9%) and dry (range: 1.0%-5.1%) blotting techniques, except for Dailies AquaComfort Plus (P=0.03). Bland-Altman analysis showed poor agreement between the techniques. The wet blotting technique yielded WC values close (around 1%) to nominal ones, in contrast to modified dry blotting technique (>=2.5%). CONCLUSIONS: The wet blotting technique is not only more reliable than the modified dry one when obtaining hydrated CL mass but also provides more accurate nominal WC measurements. Agreement between the techniques was poor. PMID- 29461300 TI - Intrasession Repeatability and Intersession Reproducibility Measurements Using VX120 Multidiagnostic Unit. AB - OBJECTIVE: The VX120 multidiagnostic unit is a multidiagnostic instrument that combines several functions: autorefraction, keratometry, corneal topography, aberrometry, pachymetry, and noncontact tonometry. The purpose of this study was to determine the intrasession repeatability and the intersession reproducibility of all parameters measured by the VX120 multidiagnostic unit in a sample of normal healthy eyes. METHODS: Three repeated measurements in the right eye of the volunteers were taken with VX120. Repeatability of the sphere, cylinder, axis, anterior corneal powers (K flat and K steep, 3-mm pupil), high- and low-order aberration root mean square (HOA-RMS and LOA-RMS, 3-mm pupil), eccentricity, white-to-white (WTW), anterior chamber depth (ACD), and central corneal thickness (CCT) (2-mm central) was analyzed. Within-subject SD (Sw), precision, repeatability, coefficient of variation (CV), and the intraclass correlation coefficient (ICC) were calculated. RESULTS: The CV was low for K flat and K steep, WTW, ACD, and CCT with a range from 0.34% to 1.16%. The CV was higher for sphere, cylinder, HOA-RMS, and LOA-RMS and eccentricity with a range among 6.92% to 54.24%. The ICC showed high values in all parameters except in HOA-RMS (0.720 0.776) and eccentricity (0.889) in first session with moderate agreement. Comparing the intrasession repeatability of first and second session, statistically significant differences (P<0.01) were found between both sessions just to the CV for all parameters (except cylinder values) measured with VX120. However, nonstatistically significant differences (P>0.13) were found for Sw, precision, and repeatability values. CONCLUSIONS: The VX120 multidiagnostic unit provides repeatable measurements in anterior corneal power (K flat and K steep), WTW, ACD, and CCT. However sphere, cylinder, HOA-RMS, LOA-RMS, and eccentricity showed worse repeatability. Intersession reproducibility showed good results with little differences between sessions in healthy subjects. PMID- 29461302 TI - Does initial use of benzodiazepines delay an adequate pharmacological treatment? A multicentre analysis in patients with psychotic and affective disorders. AB - It is established that delayed effective pharmacotherapy plays a significant role in the overall burden of psychiatric disorders, which are often treated with symptomatic drugs, that is benzodiazepines (BZDs), in relation to their rapid onset of action and safety, despite long-term side effects. We aimed to assess the influence of initial treatment with BZDs on the duration of untreated illness (DUI) and whether specific sociodemographic and clinical factors could influence the choice of BZDs as first treatment in 545 patients affected by schizophrenia, mood and anxiety spectrum disorders. Statistical analyses (one-way analysis of variance and chi) were carried out to compare patients who used BZDs as first treatment (BZD w/) and those who did not (BZD w/o). The overall DUI, irrespective of diagnosis, resulted in significantly longer in BZD w/ versus w/o patients, who also experienced more frequently anxious/depressive symptoms at onset. Furthermore, BZD w/ patients more frequently autonomously decided to look for treatment (mainly refering to psychologists or general practitioners) and experimented more frequently phobias, than BZD w/o ones. The present findings suggest that initial BZDs treatment may prolong the overall DUI, although their prescription seems to be influenced by specific sociodemographic and clinical factors. Further studies are needed to confirm the present findings. PMID- 29461301 TI - Davydov Procedure for Augmenting Vaginal Length in a Postsurgical Male-to-Female Transgender Patient. AB - Male-to-female gender reassignment surgery may lead to unsatisfactory vaginal length. No standard approaches are established to treat these patients. We present a case of vaginoplasty using the laparoscopic Davydov technique performed on a male-to-female transgender patient. Our case provides a novel approach to treating this rare condition and introduces Davydov procedure as a potentially effective and safe treatment. Preoperative endovaginal and endoanal 3-dimensional ultrasounds and a pelvic magnetic resonance imaging of the case are presented to provide details of this patient's unique anatomy. PMID- 29461304 TI - A Systematic Review of Culturally Specific Interventions to Increase Physical Activity for Older Asian Americans. AB - BACKGROUND: Physical activity (PA) is a significant modifiable risk factor for cardiovascular disease. For older adults, engaging in PA is shown to improve cardiac status, reduce cognitive, and functional decline, and improve overall quality of life. However, only 17% of Asian American adults meet the 2008 federal recommended guidelines for aerobic and muscle strengthening activity; and there is a paucity of data reporting on older Asian Americans - a rapidly growing, underserved group. While data pertaining to Asian Americans is frequently reported at the aggregate level, this masks differences (eg, language, culture, income) among Asian ethnic subgroups that may impact health behaviors. The purpose of this review was to identify intervention, and cultural adaptation strategies in studies promoting PA for older Asian Americans. METHODS: A comprehensive literature search was performed to identify interventions published between 1996-2016 focused on improving PA among older Asian Americans (> 60 years old). Data were abstracted to examine intervention study designs, cultural adaptation strategies, theoretical frameworks, and physical activity measures. RESULTS: Nine studies met the review's inclusion criteria. Community-based recruitment approaches were widely used, and all studies employed cultural adaptation to varying degrees. Most studies reported improvements in PA outcomes, focused on Chinese Americans, and relied on self-reports of PA, while few aimed to increase PA using a multi-component approach. CONCLUSIONS: Future studies would benefit from larger sample sizes, a wider representation of Asian ethnic subgroups, and concentrated efforts to implement deep level adaptations that may increase the salience and sustainability of these interventions. PMID- 29461303 TI - Agreement Between Automated and Human Measurements of Heart Rate in Patients With Atrial Fibrillation. AB - BACKGROUND: The accuracy of heart rate (HR) measurement by automated blood pressure monitors in patients with atrial fibrillation (AF) remains unclear. The authors investigate the agreement between HR measurements by 2 automated devices and human counting in patients with AF. METHODS: In 47 patients with persistent AF, HR was recorded using 2 automated blood pressure monitors: Omron M5-I and Microlife BPA100 Plus. Human counting of HR by a stethoscope was used as the reference. For each method, 3 readings were made and the mean was calculated for comparison. In addition to Wilcoxon signed rank test, the correlation between HR measurements by automated devices and human counting was determined using Spearman's rank correlation coefficient (r), and the agreement between HR measurements by both devices and human counting was validated by the Bland-Altman plot and intraclass correlation coefficient (ICC). RESULTS: Overall, we found no significant difference in HR measurements between devices and human counting (Omron vs human counting, 81.1 +/- 11.1 vs 80.2 +/- 10.8 beats per minute [bpm]; P = .21, r = 0.911; ICC, 0.954; Microlife vs human counting, 81.3 +/- 10.8 vs 80.2 +/- 10.8 bpm; P = .22, r = 0.842; ICC, 0.912). However, in patients with HR greater than 80 bpm, the HR measured by the Microlife device was significantly higher than that measured by human counting (91.1 +/- 5.2 vs 87.1 +/- 8.6 bpm, P = .034). CONCLUSION: There was a high agreement between HR measurements by 2 automated devices and human counting, but the Microlife device may overestimate HR in AF patients with HR greater than 80 bpm.

PMID- 29461305 TI - Transcatheter Aortic Valve Replacement as a Bridge to Left Ventricular Assist Device Implantation. AB - We describe a case of the pre-emptive use of transcatheter aortic valve replacement in a patient with end-stage ischemic cardiomyopathy and native aortic stenosis/aortic insufficiency as a bridge to left ventricular assist device implantation. The use of this strategy can not only medically optimize patients before left ventricular assist device implantation but also provide a minimally invasive bridge to left ventricular assist device support, avoiding concomitant surgical aortic valve replacement or closure. PMID- 29461307 TI - Are graft-versus-host-disease patients missing out on the vital occupational therapy services? a systematic review. AB - The aim of this review is to show the importance of occupational therapy/hand therapy for chronic graft-versus-host-disease (GVHD) patients and to outline the current state of the literature. GVHD of the hand can cause functional loss, reduced activities of daily life, poor social interaction, and loss of income because of limitations in work. Hand therapy, which is a specialty practised by both occupational therapists and physical therapists, has been proven to be an effective approach for hand-related musculoskeletal disorders; however, the literature search suggests that it is an underutilized specialty around the world. An electronic search was performed from 1997 to 2017 using OneFile (GALE), Medline/PubMed (NLM), Scopus (Elsevier), Science Citation Index Expanded (Web of Science), ProQuest Central (New), ProQuest Hospital Collection, Health Reference Center Academic (Gale), Health Research Premium Collection, Science Direct Journals (Elsevier), ProQuest Health & Medical Complete, Medical Database, Wiley Online Library, and SciTech Premium Collection for the period from 1994 to April 2017. Only randomized-controlled trials involving occupational therapy or hand therapy in patients with chronic hand GVHD were included in the final analysis. The search was limited to articles in English. Two reviewers independently assessed the methodological quality and extracted the data. The JADAD scoring method was used to score the articles. After the duplicates were excluded, 5466 articles were identified by the electronic database search for screening, out of which 5465 articles were excluded after reviewing. One article was further excluded on obtaining the full text as it was a case study. Hand therapy specialty, although a vital part of the recovery process for the patients with hand GVHD, is an underutilized specialty and well-designed trials are urgently needed for musculoskeletal hand GVHD, especially for focused hand therapy interventions. PMID- 29461308 TI - Interprofessional Communities of Practice in Continuing Medical Education for Promoting and Sustaining Practice Change: A Prospective Cohort Study. AB - INTRODUCTION: Standard knowledge delivery formats for CME may have limited impact on long-term practice change. A community of practice (CoP) is one tool that may enhance competencies and support practice change. This study explores the utility of an interprofessional CoP as an adjunct to a CME program in tobacco addiction treatment (Training Enhancement in Applied Counselling and Health [TEACH] Project) to promote and sustain practice change. METHODS: A prospective cohort design was utilized to examine the long-term impact of the TEACH CoP on practice change. An online survey was administered to TEACH-trained practitioners to assess perceived feasibility, importance, and confidence related to course competencies, involvement in TEACH CoP activities, engagement in knowledge transfer (KT), and implementation of new programming. Chi-square tests were used to detect differences in KT and program development associated with CoP participation. Course competency scores from immediate postcourse surveys and long-term follow-up surveys were compared. RESULTS: No significant differences in participant characteristics were found between those who did (n = 300) and did not (n = 122) participate in the TEACH CoP. Mean self-perceived competency scores were greater immediately after course than at long-term follow-up; however, self ratings of competency in pharmacological interventions and motivational interviewing were higher at follow-up. TEACH CoP participation was associated with significantly greater engagement in KT and implementation of new programming after training. DISCUSSION: The findings from this evaluation suggest the value of interprofessional CoPs offered posttraining as a mechanism to enhance practice. CME providers should consider offering CoPs as a component of training programs to promote and sustain practice change. PMID- 29461309 TI - Foreword. PMID- 29461311 TI - Looking For Food: Food Access, Food Insecurity, and the Food Environment in Rural Mississippi. AB - Mississippi has the highest food insecurity rate in the nation, and while the overall pattern of food insecurity has declined in the United States, for Mississippians it has plateaued, remaining significantly higher than prerecession rates. In addition, the food environment of the state is characterized by low healthy food access, high persistent poverty, and a primarily rural landscape. This translational research seeks to bridge thinking on agriculture policy, nutrition, food access/food insecurity in seeking to understand the paradox between obesity and poverty in rural Mississippi. Examining food system opportunities as potential solutions to food access and healthy outcomes is explored. PMID- 29461310 TI - Examining the Impact of Structural Racism on Food Insecurity: Implications for Addressing Racial/Ethnic Disparities. AB - Food insecurity is defined as "a household-level economic and social condition of limited or uncertain access to adequate food." While, levels of food insecurity in the United States have fluctuated over the past 20 years; disparities in food insecurity rates between people of color and whites have continued to persist. There is growing recognition that discrimination and structural racism are key contributors to disparities in health behaviors and outcomes. Although several promising practices to reduce food insecurity have emerged, approaches that address structural racism and discrimination may have important implications for alleviating racial/ethnic disparities in food insecurity and promoting health equity overall. PMID- 29461312 TI - A Theoretically-Grounded Investigation of Perceptions About Healthy Eating and mHealth Support Among African American Men and Women in New Orleans, Louisiana. AB - There has been a surge in diet-related mobile health (mHealth) interventions. However, diet-related mHealth research targeted toward racial/ethnic populations has been relatively limited. Focus groups with African American men and women from New Orleans, Louisiana, were conducted to (1) describe perceptions about healthy eating, (2) determine the acceptability of mHealth interventions, and (3) identify preferred mHealth intervention features. Descriptive statistics and thematic content analyses were performed. Qualitative data were organized within the context of the Theory of Planned Behavior and Social Cognitive Theory's theoretical components. Results may inform the development of mHealth research to improve eating behaviors among the target population. PMID- 29461313 TI - Sex, Race, Food Security, and Sugar Consumption Change Efficacy Among Low-Income Parents in an Urban Primary Care Setting. AB - The purpose of this study was to examine relationships between food security and parents' self-efficacy to reduce consumption of sugar-sweetened beverages and sugary snacks in a sample of parents in waiting rooms in community-based primary care clinics in West Tennessee. Results from logistic regression models underscore the need for nuanced analysis, as the results from the pooled regression models differ from those stratified by food security status. Self efficacy is an important factor for behavior change, and our study highlights the need for additional research examining how social, psychological, and behavioral factors have implications for behavior change self-efficacy.

PMID- 29461328 TI - The challenges of timely and safe HIV disclosure among perinatally HIV-infected adolescents in sub-Saharan Africa. AB - PURPOSE OF REVIEW: Improved access to antiretroviral therapy has resulted in an emerging population of adolescents living with HIV (ALHIV) mainly in sub-Saharan Africa. Full disclosure of an HIV diagnosis includes naming HIV/AIDS and is an important step in coping with HIV. We reviewed the recent trends in the rates of children/adolescents who have been informed of their HIV infection according to age groups, the barriers and the evaluated interventions aimed at improving the HIV disclosure process to ALHIV in sub-Saharan Africa. RECENT FINDINGS: Literature shows that HIV disclosure remains challenging in sub-Saharan Africa. Although full HIV disclosure rates have increased recently, this is still insufficient and occurs at a late age (median 13 years). Individual disclosure is the main practice but group sessions involving adolescent peers also exist. The practice of the disclosure is often complex, because of multiple barriers related to caregivers (fear of the parents of the breaking of the family secrecy, feelings of guilt) and to healthcare workers (lack of training, excess workload). SUMMARY: The development and evaluation of research interventions adapted to sociocultural contexts to support timely and safe HIV disclosure to ALHIV is urgently needed to reach the 90-90-90 UNAIDS targets. PMID- 29461330 TI - Sexual and reproductive health in HIV-positive adolescents. AB - PURPOSE OF REVIEW: This review aims to summarize data in the last 18 months on the sexual and reproductive health of perinatally and horizontally infected adolescents and young people living with HIV (age 13-25 years) and to highlight some key issues faced by this group of adolescents as they reach puberty and sexual debut. RECENT FINDINGS: Adolescents and young people living with HIV are a growing cohort worldwide and a significant proportion engage in high-risk sexual activity, pose risk of onward HIV transmission, yet have poor access to sexual and reproductive health (SRH) services and lack the knowledge and support to advocate for their needs. SUMMARY: Providing adolescents living with HIV with access to SRH services is essential. Integrated HIV and SRH services and peer support models work well. HIV healthcare providers should educate all young people around disclosure, treatment as prevention and adherence, options for preexposure and postexposure prophylaxis and contraception, and support them to advocate for their own sexual health. PMID- 29461329 TI - Cancer in adolescents and young adults living with HIV. AB - PURPOSE OF REVIEW: Adults living with HIV have an increased risk of malignancy yet there is little data for adolescents and young adults. We reviewed recently published cancer epidemiology, treatment, and outcome data for adolescents and young adults living with HIV (AYALHIV) aged 10 to less than 25 years between 2016 and 2017. RECENT FINDINGS: AYALHIV are at increased risk of developing cancer compared to their uninfected peers. Kaposi sarcoma and non-Hodgkin lymphoma occur most frequently with variation by geographical region. Increased cancer risk is associated with HIV-related immunosuppression and coinfection with oncogenic viruses. Published data, particularly on posttreatment outcomes, remain limited and analyses are hampered by lack of data disaggregation by age and route of HIV transmission. SUMMARY: Although data are sparse, the increased cancer risk for AYALHIV is the cause for concern and must be modified by improving global access and uptake of antiretroviral therapy, human papilloma virus (HPV) and hepatitis B virus (HBV) vaccination, screening for hepatitis B and C infection, and optimized cancer screening programs. Education aimed at reducing traditional modifiable cancer risk factors should be embedded within multidisciplinary services for AYALHIV. PMID- 29461331 TI - The Effect of Electroconvulsive Therapy on Hypoperfusion in Psychotic Bipolar Depression: A Case Study. AB - The pharmacological treatment of bipolar depression has low response rates. Twenty percent to 30% of patients have an insufficient response to medication. The guidelines suggest that electroconvulsive therapy (ECT) is the next step. The aim of this case study is to evaluate the effect of ECT on the perfusion of the brain in bipolar depression, while monitoring effects on mood and cognition. We present a case study of 56-year-old female patient who suffered from a psychotic depression and cognitive impairment. Before ECT, she took several antidepressants and atypical antipsychotics, but there was no improvement in her symptoms. By using single-photon emission computed tomography, we obtained the status of the regional cerebral blood flow and found a decreased perfusion in the anterior part of the left temporal lobe, the posterior part of the right temporal lobe, and in the left gyrus frontalis inferior. This is consistent with previous findings. Electroconvulsive therapy resulted in a resolution of the patient's depression and an improvement in her neurocognitive performance. Markedly, this was only in visual learning and working memory, domains in which the patient was already relatively stronger pre-ECT treatment. A new single-photon emission computed tomography, 4 weeks after the last ECT course, showed normalization of the regional cerebral blood flow. PMID- 29461332 TI - Improvements in Health-Related Quality of Life With Electroconvulsive Therapy: A Meta-analysis. AB - INTRODUCTION: Although the antidepressant efficacy of ECT is well documented, patient-reported outcomes after this treatment are less well characterized. The aims of the current meta-analysis are to quantify the impact of an acute course of ECT on health-related quality of life (HRQoL) and to identify related moderators, specifically post-ECT depressive symptom remission and patient age. METHODS: We searched PubMed, PsycINFO, and Web of Science databases for randomized and nonrandomized studies that report on changes in HRQoL measures after an acute course of ECT. Only studies that used the Medical Outcomes Study Short Form 36 (SF-36) instrument were included. A random effects model using the Hedges' g effect size was used in calculating the pre-post ECT outcomes on all 8 SF-36 subscales and the SF-36 total scores including the physical and mental composite scores. Subgroup analyses were conducted using remission status and age as moderators. RESULTS: Four studies contributed to this analysis. Significant improvements across all subscales of the SF-36 were observed. Large and very large effect sizes were present for both the SF-36 physical component score (PCS) and mental health component score (MCS), with the change in MCS being statistically superior to the PCS (MCS, Hedges' g = 1.28; 95% confidence interval, 1.15-1.42; PCS, Hedges' g = 0.97; 95% confidence interval, 0.86-1.07). Medium, large, and very large effect sizes were observed for SF-36 subscales scores. Post-ECT depression remission status was related to HRQoL improvement, with statistically significant differences present between remitters and nonremitters for PCS, MCS, and most SF-36 subscale scores. No significant differences were observed in improvement in HRQoL with ECT based on patient age. CONCLUSIONS: An acute course of ECT for depressive symptoms produces medium to very large effect size improvements in HRQoL across multiple components and subscales measured by the SF-36. The magnitude of the effects reported by ECT patients is greater than those that have been reported in other open-label studies of brain stimulation techniques. This study confirms that ECT plays a vital role in the treatment of the most severely ill patients with depressive disorders. PMID- 29461333 TI - Metabolic Syndrome Among Asian Indians in the United States. AB - INTRODUCTION: Metabolic syndrome (MetS), a clustering of cardiometabolic risk factors of type 2 diabetes and cardiovascular disease, disproportionately affects Asian Indians (AIs). We examined prevalence of MetS using 3 ethnicity-specific MetS criteria among immigrant AIs in the United States. We also examined associations between MetS and health promotion behaviors. OBJECTIVE: To present MetS prevalence estimates by the 3 ethnicity-specific criteria and investigate differences in health promotion behaviors among AIs with and without MetS to highlight the critical need for lifestyle modification strategies for this population. DESIGN: We analyzed data from a national cross-sectional study of 1037 AIs in the United States (2004-2006). We used the consensus criteria, International Diabetes Federation criteria, and modified criteria to estimate MetS prevalence. The Health Promotion Lifestyle Profile II scale measured health promotion behaviors. Bioclinical data (fasting blood glucose, triglyceride levels) were collected. Directed acyclic graphs and Likelihood Ratio Test assisted with model selection. Multiple imputation inference incorporated uncertainty due to missing data and made use of all available data. Adjusted multivariable logistic regression analysis tested for associations. RESULTS: Out of all participants, 40.3% met the consensus criteria, 34.8% met the International Diabetes Federation criteria, and 52.5% met the modified criteria. We found no statistically significant associations between engagement in health promotion measures and the prevalence of MetS and its criteria. CONCLUSION: Our study confirmed the high prevalence of MetS in the immigrant AI population in the United States. Our results showed that AIs with MetS did not exhibit an increased level of engagement in health promotion behaviors. We recommend continued refining of criteria for diagnosis and culturally suitable, age-appropriate strategies to increase engagement in healthier lifestyles among this high-risk population. PMID- 29461334 TI - A Patient Safety Toolkit for Family Practices. AB - OBJECTIVE: Major gaps remain in our understanding of primary care patient safety. We describe a toolkit for measuring patient safety in family practices. METHODS: Six tools were used in 46 practices. These tools were as follows: National Health Service Education for Scotland Trigger Tool, National Health Service Education for Scotland Medicines Reconciliation Tool, Primary Care Safequest, Prescribing Safety Indicators, Patient Reported Experiences and Outcomes of Safety in Primary Care, and Concise Safe Systems Checklist. RESULTS: Primary Care Safequest showed that most practices had a well-developed safety climate. However, the trigger tool revealed that a quarter of events identified were associated with moderate or substantial harm, with a third originating in primary care and avoidable. Although medicines reconciliation was undertaken within 2 days in more than 70% of cases, necessary discussions with a patient/carer did not always occur. The prescribing safety indicators identified 1435 instances of potentially hazardous prescribing or lack of recommended monitoring (from 92,649 patients). The Concise Safe Systems Checklist found that 25% of staff thought that their practice provided inadequate follow-up for vulnerable patients discharged from hospital and inadequate monitoring of noncollection of prescriptions. Most patients had a positive perception of the safety of their practice although 45% identified at least one safety problem in the past year. CONCLUSIONS: Patient safety is complex and multidimensional. The Patient Safety Toolkit is easy to use and hosted on a single platform with a collection of tools generating practical and actionable information. It enables family practices to identify safety deficits that they can review and change procedures to improve their patient safety across a key sets of patient safety issues.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

PMID- 29461335 TI - 2-(4-Methoxyphenyl)ethyl-2-acetamido-2-deoxy-beta-D-pyranoside, an analog of salidroside, contributes to neuroprotection in cerebral ischemic injury in vitro and in vivo. AB - 2-(4-Methoxyphenyl)ethyl-2-acetamido-2-deoxyb-D-pyranoside (code-named SalA-4g), an analog of salidroside, has potent neuroprotective effects. In this study, the pharmacological properties of SalA-4g were evaluated in primary cortical neurons exposed to oxygen and glucose deprivation and in a rat model of transient middle cerebral artery occlusion. The results of pharmacokinetic and brain distribution studies indicated that SalA-4g could pass through the blood-brain barrier with a relatively short elimination time. 3-[4,5-Dimethyl-2-thiazolyl]-2,5-diphenyl tetrazolium bromide assay, terminal deoxynucleotidyl transferase dUTP nick-end labeling, and Annexin V staining collectively showed that SalA-4g inhibited neuronal viability loss and apoptosis in a concentration-dependent manner in an oxygen and glucose deprivation model. Fluorine-18-fluorodeoxyglucose PET/CT imaging indicated that SalA-4g improved metabolic recovery in the ischemic hemisphere in a rat middle cerebral artery occlusion model. Our findings provide further evidence of the potential therapeutic applications of SalA-4g for the treatment of cerebral ischemic injury. PMID- 29461336 TI - Sex differences in antinociceptive response to Delta-9-tetrahydrocannabinol and CP 55,940 in the mouse formalin test. AB - Cannabinoids have shown promise for the treatment of intractable pain states and may represent an alternative pharmacotherapy for pain management. A growing body of clinical evidence suggests a role for sex in pain perception and in cannabinoid response. We examined cannabinoid sensitivity and tolerance in male and female mice expressing a desensitization-resistant form (S426A/S430A) of the cannabinoid type 1 receptor (CB1R). Mice were assessed for acute and inflammatory nociceptive behaviors in the formalin test following pretreatment with either vehicle or mixed CB1R/CB2R agonists, Delta-9-tetrahydrocannabinol ([INCREMENT] THC) (1-6 mg/kg) or CP 55,940 (0.06-0.2 mg/kg). Tolerance to the effects of 6 mg/kg [INCREMENT]-THC or 0.1 mg/kg CP 55,940 was examined by the formalin test following chronic daily dosing. Female mice showed decreased sensitivity to the effects of [INCREMENT]-THC and CP 55,940 compared with male mice. The S426A/S430A mutation increased the attenuation of nociceptive behaviors for both agonists in both sexes. Female mice displayed delayed tolerance to [INCREMENT]-THC compared with male mice, whereas the S426A/S430A mutation conferred a delay in tolerance to [INCREMENT]-THC in both sexes. Male S426A/S430A mutant mice also display resistance to tolerance to CP 55,940 compared with wild-type controls. This study demonstrates sex and genotype differences in response for two different cannabinoid agonists. The results underscore the importance of including both male and female mice in preclinical studies of pain and cannabinoid pharmacology. PMID- 29461337 TI - Habitual action video game players display increased cortical thickness in the dorsal anterior cingulate cortex. AB - Action video game players (aVGPs) display increased performance in attention based tasks and enhanced procedural motor learning. In parallel, the anterior cingulate cortex (ACC) is centrally implicated in specific types of reward-based learning and attentional control, the execution or inhibition of motor commands, and error detection. These processes are hypothesized to support aVGP in-game performance and enhanced learning though in-game feedback. We, therefore, tested the hypothesis that habitual aVGPs would display increased cortical thickness compared with nonvideo game players (nonVGPs). Results showed that the aVGP group (n=17) displayed significantly higher levels of cortical thickness specifically in the dorsal ACC compared with the nonVGP group (n=16). Results are discussed in the context of previous findings examining video game experience, attention/performance, and responses to affective components such as pain and fear. PMID- 29461338 TI - Reading Among Nursing and Nonnursing Students in Undergraduate Education. AB - Promoting reading compliance is a common concern in undergraduate education. This study described the reading behaviors, preferences, and perceptions of 519 undergraduate nursing and nonnursing students concerning course-related reading assignments. Mean time completing assigned course readings for nursing students was 6.63 hours per week; it was similar for other majors (6.73 hours). Nonnursing majors read a greater percentage of their assigned readings than nursing students (t = -6.59, P < .01). Implications highlight strategies faculty can implement to facilitate student reading. PMID- 29461339 TI - Neoadjuvant Bleomycin, Etoposide, and Cisplatin (BEP) Chemotherapy in the Treatment of Extensively Advanced Yolk Sac Tumors: A Single Center Experience. AB - OBJECTIVE: This study aimed to investigate the role of neoadjuvant bleomycin, etoposide, and cisplatin (BEP) regimen in patients with extensively advanced yolk sac tumors (YSTs). METHODS: Between July 1982 and December 2015, a total of 58 patients with YST were initially treated at our institution, among which 18 were evaluated to be inoperable and received neoadjuvant BEP regimen. They were either too debilitated by the disease [Eastern Cooperative Oncology Group Performance Status Scale (ECOG ps) >=2] to undergo a major surgery or were with too extensively disseminated lesions to be optimally debulked. This cohort of patients was retrospectively reviewed. RESULTS: One or 2 cycles of BEP regimen were prescribed to the majority of patients preoperatively. At the completion of neoadjuvant chemotherapy, 17 of them had ECOG ps of 1 or less. Seventeen (94.4%) exhibited clinical partial tumor regression, and 1 (5.6%) had clinical stable disease. Pathological complete tumor regression was observed in 2 (11.1%) patients, whereas the remaining 16 (88.9%) had nearly complete pathological regression. Seventeen patients were cytoreduced to no macroscopic residual disease; the remaining 1 was cytoreduced to macroscopic residual disease of 2 cm or less. No major surgical complications occurred. After a median follow-up of 83.5 months, 17 patients were free of recurrence. Five-year disease-free survival and overall survival were both 94.4%. Fertility-sparing surgery was carried out in all the 17 patients with the desire to preserve their fertility, and 5 infants were delivered in 6 patients who attempted conception. CONCLUSIONS: One or 2 cycles of neoadjuvant BEP regimen followed by cytoreductive surgery offer a chance for cure in extensively advanced patients with YSTs and help pave the way for fertility-sparing surgery. PMID- 29461340 TI - Attitudes About Cognitive Screening: A Survey of Home Care Physical Therapists. AB - BACKGROUND AND PURPOSE: Home care physical therapists (PTs) are inconsistent regarding cognitive screening, possibly because screening tools were traditionally considered the domain of other home care disciplines, or because therapists perceive their dementia training to be inadequate. A cross sectional study was designed to survey home care therapists' attitudes and beliefs about the management of persons with dementia and to find out whether any specific cognitive tools or measures are currently used. METHODS: A 5-point Likert-type survey was administered to home care PTs via an online survey. Three state home care associations and individual home care agencies agreed to share the survey link. The survey was also made available to American Physical Therapy Association members through the Home Health and Geriatric Section listservs. RESULTS AND DISCUSSION: Two hundred fifty-one PTs opened the survey and 233 completed the survey. Respondents included 180 females and 53 males. Seventy-four had a bachelor's degree (BS), 53 held a master's degree (MS), 104 had achieved a doctor of physical therapy (DPT) or doctor of philosophy (PhD) degree, and 2 did not provide this information. Significant differences were found between those with the highest doctoral degrees and those with master's or bachelor's degrees (P = .01) regarding whether they were qualified to screen (strongly agree, agree) for cognitive deficits. Therapists with the highest degrees also attended continuing education for dementia training more than those with less formal education (P = .042.) Gender differences were found in 2 questions regarding positive outcomes (P = .010 and .42); for both questions, males were more likely to believe that dementia has a negative impact. Eighty-seven percent indicated that PTs are qualified (strongly agree, agree), but only 53% said that they possess the necessary skills (strongly agree, agree) to perform cognitive screens. Specialty certification revealed significant differences in several of the questions. No significance was found for any question regarding years of practice or years in home care. The Mini-Mental State Examination and the Clock Drawing Test were most frequently cited among PTs who conduct cognitive screening. CONCLUSIONS: Physical therapists recognize that they are qualified to perform cognitive screening but may need additional training to utilize cognitive findings to enhance interventions and outcomes in home care. More research is needed to determine which screens are most relevant for therapist use and to examine the effect of cognitive screening on therapy outcomes. PMID- 29461341 TI - Influence of the Initial Sagittal Lumbar Alignment on Clinical and Radiological Outcomes of Single-Level Lumbar Total Disc Replacements at a Minimum 2-Year Follow-up. AB - STUDY DESIGN: Retrospective cohort study OBJECTIVE.: To analyze the clinical and radiographic outcomes of patients undergoing a one-level lumbar total disc replacement (TDR), according to the initial sagittal alignment of the spine. SUMMARY OF BACKGROUND DATA: No authors have highlighted correlation between the initial spinopelvic parameters and the postoperative outcome after a one-level TDR. METHODS: Seventy-eight patients were included: 14 TDR at L4-L5 and 64 TDR at L5-S1 level. Clinical assessment was performed on leg pain and axial back pain Visual Analog Scale (VAS), Oswestry Disability Index, and Short Form-36 Health Survey. Radiographic assessment included full spine standing anteroposterior and lateral films. Data were compared according to the initial lumbar sagittal alignment described by Roussouly. RESULTS: Forty-five female patients and 33 male patients with a mean age of 41.7 years (95% confidence interval [40.3-43.1]) were included. The mean follow-up was 46.4 months (95% [40.6-51.6]). Two patients were considered as Roussouly type 1 (2.6%), 36 patients as type 2 (46.2%), 33 patients as type 3 (42.3%), and 7 patients as type 4 (9%). Preoperatively, there were no clinical differences depending on Roussouly's type of back. Pelvic incidence (P < 0.001), sacral slope (P < 0.001), lumbar lordosis (P < 0.001), and spinosacral angle (P < 0.001) were different between the Roussouly's types of back. Postoperative clinical outcome improved (P < 0.001) but did not vary according to the Roussouly types except for leg pain VAS (P = 0.03). Post hoc tests did not reveal difference between the Roussouly's types and leg pain VAS. Postoperative radiographic outcomes did not change excepted for the lumbar lordosis (P < 0.001), thoracic kyphosis (P = 0.007), and spinosacral angle (P = 0.02). The Roussouly type had no effect on the postoperative course of radiographic parameters. CONCLUSION: Equivalent clinical and radiographic outcomes have been highlighted independently of the increasing of the sacral slope for patients with one-level lumbar TDR. LEVEL OF EVIDENCE: 3. PMID- 29461342 TI - Leveraging Google Trends, Twitter, and Wikipedia to Investigate the Impact of a Celebrity's Death From Rheumatoid Arthritis. AB - BACKGROUND: Technological advancements, such as patient-centered smartphone applications, have enabled to support self-management of the disease. Further, the accessibility to health information through the Internet has grown tremendously. This article aimed to investigate how big data can be useful to assess the impact of a celebrity's rheumatic disease on the public opinion. METHODS: Variable tools and statistical/computational approaches have been used, including massive data mining of Google Trends, Wikipedia, Twitter, and big data analytics. These tools were mined using an in-house script, which facilitated the process of data collection, parsing, handling, processing, and normalization. RESULTS: From Google Trends, the temporal correlation between "Anna Marchesini" and rheumatoid arthritis (RA) queries resulted 0.66 before Anna Marchesini's death and 0.90 after Anna Marchesini's death. The geospatial correlation between "Anna Marchesini" and RA queries resulted 0.45 before Anna Marchesini's death and 0.52 after Anna Marchesini's death. From Wikitrends, after Anna Marchesini's death, the number of accesses to Wikipedia page for RA has increased 5770%. From Twitter, 1979 tweets have been retrieved. Numbers of likes, retweets, and hashtags have increased throughout time. CONCLUSIONS: Novel data streams and big data analytics are effective to assess the impact of a disease in a famous person on the laypeople.

AB - BACKGROUND: Fibromyalgia is a chronic pain syndrome, characterized by chronic musculoskeletal pain, fatigue, and mood disturbances. There are nearly no data on the effect of medical cannabis (MC) treatment on patients with fibromyalgia. METHODS: Data were obtained from the registries of 2 hospitals in Israel (Laniado Hospital and Nazareth Hospital) on patients with a diagnosis of fibromyalgia who were treated with MC. After obtaining patient consent, demographic, clinical, and laboratory parameters were documented. All the patients also completed the Revised Fibromyalgia Impact Questionnaire regarding the period before and after MC treatment. RESULTS: Thirty patients were identified, and 26 patients were included in the study. There were 19 female patients (73%), and the mean age of the study group was 37.8 +/- 7.6 years. The mean dosage of MC was 26 +/- 8.3 g per month, and the mean duration of MC use was 10.4 +/- 11.3 months. After commencing MC treatment, all the patients reported a significant improvement in every parameter on the questionnaire, and 13 patients (50%) stopped taking any other medications for fibromyalgia. Eight patients (30%) experienced very mild adverse effects. CONCLUSIONS: Medical cannabis treatment had a significant favorable effect on patients with fibromyalgia, with few adverse effects.

PMID- 29461350 TI - Leading Change: A Case Study of the First Independent Critical-Access Hospital to Achieve Magnet(r) Designation. AB - OBJECTIVE: The aim of this study was to understand how nurses in a 25-bed critical-access hospital (CAH) led change to become the 1st to achieve Magnet(r). BACKGROUND: Approximately 21% of the US population lives in rural areas served by CAHs. Rural nurse executives are particularly challenged with limited resources. METHODS: Staff nurses, nurse managers, interprofessional care providers, the chief nursing officer, and board of directors (n = 27) were interviewed. Observations of hospital units and administrative meetings were done, and hospital reports were analyzed. RESULTS: Nine themes emerged to support a conceptual model of leading change. The CAH spent 3 years of its 6-year journey establishing organizational readiness. Nurses overcame complex challenges by balancing operational support and fostering relationships. The Magnet journey led to significantly improved nurse and patient outcomes. A new organizational culture centered on shared governance, evidence-based practice, and higher education emerged. CONCLUSIONS: The journey to Magnet leads to improved nurse, patient, and organization outcomes.

PMID- 29461352 TI - Implementation and Evaluation of Shared Medical Appointments in Veterans With Diabetes: A Quality Improvement Study. AB - OBJECTIVE: The aim of this study is to implement and evaluate shared medical appointments (SMA) in veterans with diabetes. BACKGROUND: Health systems are challenged to meet the complex care needs of veterans with diabetes. Use of SMA has resulted in significant improvements in A1c, blood pressure, and self management skills in this population. METHODS: Shared medical appointments were implemented in a Veterans Administration Health System. A1c, blood pressure, total cholesterol, high-density lipoprotein, low-density lipoprotein, triglycerides, weight, and height were collected at baseline, 3 months, and 6 months; hospitalization anytime; and veteran satisfaction at baseline and 6 months. RESULTS: From October 15, 2015, to March 15, 2016, 30 male veterans with diabetes participated in monthly SMA. Outcome measures except for high-density lipoprotein improved significantly (P < .02) from baseline to 6 months. No veterans were hospitalized. Veteran satisfaction increased significantly (P < .001). CONCLUSION: Shared medical appointment can be a highly effective intervention for veterans with diabetes. Nursing leaders need to be at the forefront of implementing SMA for populations with chronic conditions.

AB - This study examined whether the closure of several inpatient obstetric units in rural New Hampshire affected birth outcomes. It is a secondary analysis of birth certificate data from 2005 through 2012 and includes 5881 births. There were no changes in perinatal outcomes. When examining outcomes based on distance travelled to place of birth, controlling for closures, women who traveled greater than 30 miles had fewer prenatal visits and lower birth weight and gestational age infants. Community services that provide prenatal care and/or home visiting are even more important when obstetric units are not available in the community.

AB - The purpose of this study is to examine expressed emotion and the relationship between expressed emotion and suicide probability in psychiatric outpatients (N = 350). Patients who did not receive support from anyone scored higher on the Level of Expressed Emotion (LEE) Scale than those who were supported by family, friends, or their physician provider. Scores by patients, who selected their spouse as a key person, scored higher on the LEE than those who chose one of their children. Spouses on the LEE were often depicted as being more intrusive, reactive, and intolerant when compared with their children. The probability of suicide increased as the LEE scores on expressed emotion increased. PMID- 29461360 TI - Parenting Stress in Fathers of Children With Type 1 Diabetes. AB - The purpose of the present study was to evaluate generic and pediatric parenting stress in an international sample of fathers of children with type 1 diabetes. Two-hundred forty-nine fathers of children ages 2 to 10 years with type 1 diabetes completed the Parenting Stress Index, Pediatric Inventory for Parents, Dads' Active Disease Support Scale (DADS), Self-Care Inventory, and a demographic/disease-related questionnaire online. More frequency of pediatric parenting stress was associated with greater general parenting stress (r = -0.25, P < .001), DADS Involvement (r = 0.18, P < .01). The present findings suggest that paternal involvement in management of the child's T1 can have meaningful implications for disease management outcomes.

PMID- 29461361 TI - Health and Health Care From the Perspective of Intimate Partner Violence Adult Female Victims in Shelters: Impact of IPV, Unmet Needs, Barriers, Experiences, and Preferences. AB - Intimate partner violence (IPV) predicts poor health for victims and their children, but little is known about the perspective of victims. This study reports the perspectives of adult female IPV victims about the impact of IPV on their health and barriers of health care access for themselves and their children. The majority rated their health as good to excellent (69%). However, 83.5% indicated that IPV negatively affected their health; 53.5% had unmet health care needs. Mental health care was the most common unmet need for women; children's unmet needs were immunizations and preventive care. Transportation difficulties posed the biggest barrier to health care access. PMID- 29461363 TI - Hemodynamic Assessment with SPY-Indocyanine Green Angiography in Expansion Period: A Study for Expansion Capsule Pressure Optimization. AB - Tissue expansion-related severe complication exists, and the poor blood supply is one of the causes. After decades of negative correlation between capsule pressure and blood flow was verified, the widely recognized expansion capsule pressure is still absent. A prospective randomized controlled trial was performed to explore the optimal expanding capsule pressure. Thirty subjects were randomly divided into 5 groups, received a weekly expanding on 60-, 70-, 80-, 90-, and 100-mm Hg capsule pressure, respectively. All patients achieved 8-week follow-up; hemodynamic assessment by SPY-indocyanine green (ICG) angiography was taken every 2 weeks. Standardized indexes from SPY-ICG angiography were used to assess the blood supply, in which the ratio of ingress rate and the ingress rate of normal skin (IR/NIR) reflects the arterial perfusion level, and the ratio of Engress Rate and IR (ER/IR) indicates the venous reflux level. The expansion-related adverse events during the trial were recorded. The IR/NIR and the ER/IR are both obviously negatively correlated to the capsule pressure of tissue expander (P <= 0.05, the ER/IR's correlation coefficient = -0.453; the IR/NIR's correlation coefficient = -0.482). The post-expansion IR/NIR increased significantly after 8 weeks of expansion (P <= 0.05) in 90-mm Hg group. And the post-expansion ER/IR was significantly elevated (P <= 0.05) in 80 and 90-mmHg groups. There were 2 expansion-related complications reported in 100-mm Hg group, whereas no complication occurred in 4 other lower groups. SPY-ICG angiography is an objective measurement for tissue expansion hemodynamic monitoring. The expanding capsule pressure of 80 to 90 mm Hg is a reasonable upper limit. PMID- 29461364 TI - The Effect of Unfocused Extracorporeal Shock Wave Therapy on Bone Defect Healing in Diabetics. AB - AIM: The purpose of this study was to evaluate the effect of the unfocused extracorporeal shock wave therapy (ESWT) on healing of mandible ramus defects in diabetic rats. MATERIAL AND METHOD: Forty male Wistar albino rats were used in the experiment. All animals were randomly divided into 2 main groups, nondiabetic and diabetic. Critical-sized defects were created on ramus in all rats. ESWT was performed to half of rats in each group at 3 sessions after surgery. Animals were euthanized at either fourth or eighth week. Stereological and radiologic examination was performed. Data were statistically analyzed by one-way variance analysis and Tukey post-hoc test. RESULTS: Hounsfield Unit values were higher in DE group than DE group in both 8-week and 4-week groups (P > 0.05). In both 4 week and 8-week diabetic groups, higher value was observed when compared with nondiabetic groups (P > 0.05). According to stereological results, in 4-week groups, there was a higher new bone, connective tissue, and neovascularization volume in DE group than DE group and in DE group than DE group. These results are similar for the 8-week groups except NV volume. CONCLUSION: It was found that ESWT application has no positive effect on the healing of critical-sized bone defects in nondiabetics whereas promising effects in diabetics were observed. PMID- 29461366 TI - Long-Term Skeletal Changes After Maxillary Distraction Osteogenesis in Growing Children With Cleft Lip/Palate. AB - PURPOSE: To systematically evaluate the skeletal changes after maxillary distraction osteogenesis (DO) in growing patients with cleft lip with or without cleft palate (CL/P). MATERIALS AND METHODS: Electronic databases, gray literature, and reference list searches were conducted. Articles reporting prospective and retrospective studies that included patients <16 years old (N >= 6) who had received DO surgery for correction of a midfacial hypoplasia due to CL/P, and the period of follow-up persisted >1 year were reviewed. The original articles were evaluated by 2 investigators to ensure that they met the selection criteria. A methodologic quality assessment tool was used to evaluate the quality of selected studies. Twenty-six studies met the initial search criteria, and 9 articles included 101 growing patients with maxillary hypoplasia due to CL/P who received DO surgery were finally selected and analyzed. RESULTS: The results showed that long term after maxillary advancement with DO, the horizontal relapse in A-point was <15% in 3 studies, 20% to 25% in 1 study, 30% to 35% in 3 studies, and >40% in 1 study. Totally, the range of horizontal relapse in A-point was 11.9% to 45.9%. Similarly, the relapse in SNA angle was <30% in 1 study, 30% to 40% in 3 studies, and >40% in 2 studies. Totally, the range of relapse in SNA was 25.7% to 77%. Two studies showed that the vertical relapse in A-point were 137% and 208%, and in the PNS point were 65% and 62.7%. CONCLUSION: Although findings demonstrated that DO is an effective treatment method for severe maxillary hypoplasia in growing patients with CL/P, there is a relatively high amount of skeletal relapse both in horizontal and vertical dimension. Thus, the first proposed alternative for CL/P patients would be to select the correct primary procedure to decrease damage and avoid unnecessary scars. Then appropriate preoperative and postoperative care is necessary to prevent postoperative relapse. In addition, overcorrection also may be a possible alternative for compensation of postoperative relapse. PMID- 29461365 TI - Alternatives to Autologous Bone Graft in Alveolar Cleft Reconstruction: The State of Alveolar Tissue Engineering. AB - Alveolar cleft reconstruction has historically relied on autologous iliac crest bone grafting (ICBG), but donor site morbidity, pain, and prolonged hospitalization have prompted the search for bone graft substitutes. The authors evaluated bone graft substitutes with the highest levels of evidence, and highlight the products that show promise in alveolar cleft repair and in maxillary augmentation. This comprehensive review guides the craniofacial surgeon toward safe and informed utilization of biomaterials in the alveolar cleft.A literature search was performed to identify in vitro human studies that fulfilled the following criteria: Level I or Level II of evidence, >=30 subjects, and a direct comparison between a autologous bone graft and a bone graft substitute. A second literature search was performed that captured all studies, regardless of level of evidence, which evaluated bone graft substitutes for alveolar cleft repair or alveolar augmentation for dental implants. Adverse events for each of these products were tabulated as well.Sixteen studies featuring 6 bone graft substitutes: hydroxyapatite, demineralized bone matrix (DBM), beta-tricalcium phosphate (TCP), calcium phosphate, recombinant human bone morphogenic protein-2 (rhBMP-2), and rhBMP7 fit the inclusion criteria for the first search. Through our second search, the authors found that DBM, TCP, rhBMP-2, and rhBMP7 have been studied most extensively in the alveolar cleft literature, though frequently in studies using less rigorous methodology (Level III evidence or below). rhBMP-2 was the best studied and showed comparable efficacy to ICBG in terms of volume of bone regeneration, bone density, and capacity to accommodate tooth eruption within the graft site. Pricing for products ranged from $290 to $3110 per 5 mL.The balance between innovation and safety is a complex process requiring constant vigilance and evaluation. Here, the authors profile several bone graft substitutes that demonstrate the most promise in alveolar cleft reconstruction. PMID- 29461367 TI - The Natural History of Cranial Morphology in Sagittal Craniosynostosis. AB - BACKGROUND: Children with craniosynostosis have abnormal head shapes. Parents frequently ask whether the abnormal head shape will get worse with time. However, there is no information in the literature to indicate whether the deformity gets worse. OBJECTIVE: To assess the progression of cranial morphology in children with unoperated craniosynostosis. METHODS: A retrospective review of all children with unoperated sagittal craniosynostosis who were referred to the Craniofacial Clinic at the Hospital for Sick Children (SickKids) was conducted. Serial 3D photographs of patients with sagittal craniosynostosis who have not undergone surgical correction were included in the study. There were 14 cases included, with 9 males and 5 females. Ages at time of scans ranged from 3 months to 5 years of age (mean = 28.3 months, SD = 28.2 months). Nine patients had the first scan at age of <12 months. Multiple scans for each patient were sized for volume over time and compared with a normative skull database. RESULTS: The results of measuring skull volume changes over time revealed no significant difference from infants without craniosynostosis. Furthermore, there cranial index was stable over time in patients with craniosynostosis. CONCLUSION: The severity of craniosynostosis does not worsen or improve with time. Parents having difficulty in deciding to proceed with surgical correction of craniosynostosis can be reassured that the skull deformity will remain stable with the growth of their child if they decide not to proceed with surgical correction. PMID- 29461368 TI - Safety Outcomes in Endoscopic Versus Open Repair of Metopic Craniosynostosis. AB - BACKGROUND: Premature fusion of the metopic suture leads to a range of clinical presentations, with more severe patients presenting characteristically with trigonocephaly. Endoscopic-assisted correction of craniosynostosis is emerging as an alternative to the gold-standard open cranial vault remodeling. While there are several documented benefits of endoscopic correction, the management of craniosynostosis varies widely in the literature with little consensus as to the preferred timing and surgical technique for repair. The purpose of this study was to investigate the safety outcomes of endoscopic versus open surgery at our institution. METHODS: This retrospective cohort study included all patients diagnosed with metopic craniosynostosis who underwent open or closed surgical management and received at least 6 months of follow-up. Data extraction was performed via chart review and included demographic information and safety outcome variables. RESULTS: During the study period, 17 patients who met our inclusion criteria were treated by the multidisciplinary craniofacial team at our institution. Eight patients underwent endoscopic surgery and 9 underwent open surgery. The mean age at surgery was significantly higher in the open surgery group than the endoscopic surgery group (13.7 months versus 2.3 months, respectively). Estimated blood loss, percent estimated blood volume lost, transfusion volume, procedure length, hospital length of stay, and intensive care unit (ICU) length of stay were all significantly higher in the open surgery group compared with the endoscopic group. CONCLUSIONS: In our patient population, endoscopic surgery for metopic craniosynostosis had an improved safety profile versus open surgery based on reduced procedure length, estimated blood loss, volume of blood transfusion, and length of stay in the ICU and hospital. PMID- 29461369 TI - Reevaluation of Mandibular Morphometry According to Age, Gender, and Side. AB - AIM: This study aims to reevaluation the linear and angular measurements of mandibles with multidetector computed tomography (MDCT) that is a new method and used frequently in recent years. MATERIALS AND METHODS: The archived MDCT images of 100 adult patients (age range, 15-74 years) without mandibular operation and trauma history were evaluated retrospectively. Mandibular ramus heights, maximal mandibular length, mandibular symphysis height, mandibular angles, and mandibular foramen distance measurements were performed on MDCT images. All measurement parameters were analyzed by gender, age groups, and sides. RESULTS: Mandibular linear length measurements were higher in males than in females (P < 0.05). Only mandibular symphysis height was statistically significantly different in age groups (P < 0.05). The Angle 1 (gonial angle) was found to be significantly higher in females (P < 0.05). The Angle 3 (right condyle-gnathion-left condyle angle) was observed to be significantly higher in the 60+ age group (P < 0.05). The 3 of the mandibular foramen measurements (distance from the front edge, distance to gonion, and height of lingula) were found to be higher in males than in females (P < 0.05). There were no significant differences according to age groups in these measurements. The lengths of the mandibular canals were higher in males (44.72 mm) than in females (41.68 mm). There was no statistically significant difference was found between gender, age groups, and sides of mandibular canal length. CONCLUSION: The MDCT was found to be a reliable method for the detection of mandibular morphometry when compared with the results of other radiographic images studies. PMID- 29461370 TI - Nasal Cavity Actinomycosis Mimicking Rhinolith. AB - Actinomycosis is a subacute-to-chronic bacterial infection caused by filamentous, gram-positive, non-acid-fast, anaerobic-to-microaerophilic bacteria. It is characterized by continuous spread, suppurative and granulomatous inflammation, and formation of multiple abscesses and sinus tracts that may discharge sulfur granules. Although the most common clinical forms of actinomycosis are cervicofacial, involvement of the nose and paranasal sinuses are extremely rare. Furthermore, nasal cavity actinomycosis mimicking rhinolith has not been reported in the literature previously. This article reports a patient of nasal cavity actinomycosis causing symptoms similar to those of a rhinolith, which was successfully treated by surgical debridement and antibiotic therapy. PMID- 29461371 TI - Facial Artery as a Recipient Vessel for Extensive Scalp Reconstruction With Free Omental Flap Without Vein Graft. AB - Most patients with reconstruction for extensive scalp defects require the use of a free flap. The suitability of the recipient vessel has a major impact on the surgery and postoperative outcome. Flaps that can be used to reconstruct the total scalp with a single flap include the latissimus dorsi (LD) and omental flaps; the LD flap is generally preferred since the omental flap results in relatively larger donor site morbidity. The recipient vessel most commonly used for scalp defect reconstruction is the superficial temporal vessel. The authors report a patient with successful total scalp reconstruction using a free omental flap on a patient whose bilateral superficial temporal arteries could not be used and who did not have available LD on both sides due to previous LD free flap surgeries for recurrent scalp angiosarcoma. In this patient, direct anastomosis of the flap to the right facial artery was performed without pedicle lengthening, such as vein graft or arteriovenous loops, and favorable outcome was achieved in terms of facial contour after recovery. The free omental flap is useful for reconstruction of extensive scalp defects without additional complex surgical procedures when other flaps are not viable or when the recipient vessel is located at a far distance. PMID- 29461372 TI - A Standard Operating Procedure of Clean and Fast Craniotomy Without Application of Raney Clips. AB - Clean and fast craniotomy and closure (CAC) is a fundamental part of modern microneurosurgery, and is an essential technique that young neurosurgeons shall master. The hemostatic instruments of CAC have evolved from forceps to raney clips. Thanks to the wide application of bipolar coagulation, local infiltration anesthesia combined with cauterization is become an effective method of hemostasis. The authors worked out a standard operating procedure (SOP) of CAC assisted by fishhooks without the application of raney clips. According to the authors' experience, the average time spent on CAC decreased from more than 1 hour to <40 minutes. Owning to little bleeding, the operative field is clean throughout the procedure. Patients also experience less pain and enjoy an earlier discharge. With few complications, the authors believe that this cost-effective SOP may become a cornerstone of early recovery after surgery. PMID- 29461373 TI - Single Session Facial Lipostructure by Using Autologous Fat Mixed With Platelet Rich Fibrin Injected by Using Facial Autologous Muscular Injection Technique. AB - AIM: This study was designed to evaluate the role of single session autologous facial fat grafting in correcting facial asymmetries after mixing it with platelet-rich fibrin (PRF) and injecting them into rich vascular facial muscular plane. MATERIALS AND METHODS: Fifteen patients (12 females and 3 males) with age ranging from 18 years to 40 years were included in this study and followed up during 6 months, all the patients were treated in the Al-Shaheed Ghazi Al-Hariri for specialized surgeries hospital (Medical City, Baghdad, Iraq).Autologous fat with PRF injected in facial muscular plane was the standardized method in the treatment of acquired and congenital facial defects.Results were evaluated by 2 plastic surgeons using visual analogue scale.Interexaminer and intraexaminer calibration of the visual analogue scale were carried out by using paired t test. RESULTS: This prospective study showed that the majority of patients (73.3%) needed only a single session for creating a noticeable improvement in facial volumes and contours. CONCLUSIONS: Mixing fat with PRF and injecting them by using facial autologous muscular injection technique offers better graft survival by utilizing the growth factors and cytokines in PRF clot together with rich vascular plexus in the muscular layer consequently. PMID- 29461374 TI - Crushed Cartilage: A Rescue Procedure in Rhinoplasty. AB - While the use of crushed cartilage is now universally recognized as a valid procedure in rhinoplasty to mask irregularities and eliminate slight deficits, there is still no consensus as to the optimal degree of crushing and the rate of graft resorption over time. With a view to casting light on these 2 important aspects and providing some guidelines, the authors present a study of 123 patients subjected to grafts of cartilage with different degrees of crushing in the different areas of the nasal pyramid: upper third (45 patients), middle third (40), and lower third (38). The degree of crushing was medium for 95 patients and high for 28 who presented thinner and less elastic skin. Comparison of the performance over time of the cartilage grafts inserted in the same areas but with different degrees of crushing provides important indications as regard the best way of preparing the material. The results proved satisfactory with improvements for all of the 95 patients subjected to grafts of moderately crushed cartilage. The initial defect was instead still present, albeit with some partial improvement, at a distance of 12 months in 17 of the 28 patients where highly crushed cartilage was used. The study suggests that a moderate degree of crushing offers better results as regard flexibility and stability over time. PMID- 29461375 TI - Parotid Mucoepidermoid Carcinoma Mimicking a Large Mucocele. AB - Mucoepidermoid carcinoma is a malign tumor involving the parotid gland and minor salivary glands. Parotid pure cystic mucoepidermoid carcinoma can also masquerade mucocele, and hence, histopathological examination is crucial to distinguish the 2. Herein, the authors report a patient of mucoepidermoid carcinoma presenting as an asymptomatic mucocele-like cystic parotid mass. A 69-year-old female presented with cystic parotid mass; her examination findings and diagnostic imaging were consistent with that of mucocele. Histological examination revealed mucoepidermoid carcinoma. This case indicates that parotid mucocele-like cysts should be included in the differential diagnosis of malign salivary gland tumors. PMID- 29461376 TI - Modified Unilateral Pedicled V-Y Advancement Flap for Scalp Defect Repair. AB - Reconstruction of scalp defects caused by tumor resection or trauma is very challenging. A majority of the surgeons prefer to use local flap rather than skin graft or free flap for scalp defects repair. The aim of this study is to investigate the technique of modified unilateral pedicled V-Y advancement flap for the reconstruction of scalp defect.A retrospective review was performed in a series of 18 patients who had a modified unilateral pedicled V-Y advancement flap to restore scalp defect from May 2013 to January 2017. Their mean age is 58 (24 78) years. These patients suffered from basal cell carcinoma, seborrhoeic keratosis, squamous cell carcinoma, or trauma on the scalp. All of them underwent preoperative Doppler scanning to identify the scalp arteries and then individually designed. The flap size ranged from 33 * 50 mm to 68 * 105 mm. Patients were followed for an average of 12 months postoperatively (ranged from 6 to 37 months). No major complications occurred, only 2 cases had a minor distal epidermal necrosis or obstruction of venous backflow observed for the first 3 days of the surgery, and they both healed well. Modified unilateral pedicled V-Y flap technique with fairly rapid recovery and acceptable reorientation of hair follicles leads to esthetical outcome and patient satisfaction. Most importantly, no tumor recurrence at the original site during the follow-up period was seen.The modified unilateral pedicled V-Y advancement flap is a simple but efficient technique, particularly suitable for the repair of small and medium size scalp defects with advantages including the safety of the procedure and overall esthetic results like hairline preservation and less scarring when compared to other local flap techniques. PMID- 29461377 TI - Total Lower Lip Reconstruction With Functional Gracilis Free Muscle Flap. AB - Free flaps based on static slings principles cannot provide esthetic and functional outcomes at a desired level in total or close to total lip loss. Therefore, dynamic methods have become a current issue in recent years and especially the idea of functional gracilis free muscle flap has been suggested. In this study, we present a case of a successful total lower lip repair with this flap.In a 78-year-old female patient who was diagnosed with squamous cell carcinoma involving the entire lower lip, bilateral modified radical neck dissection and full-thickness total resection with 1 cm surgical margin so as to include both commissures of the tumor were performed and then a free gracilis muscle flap was transferred from the same side. After microvascular anastomoses, the motor nerve of the flap was coapted to the marginal mandibular branch of the fascial nerve. The entire intra- and extraoral surfaces of the flap were covered with a partial-thickness skin graft which was taken from the right thigh. There was no any intra- or early postoperative complication. The skin graft and flap survived without any problem.In the controls of the patient who was followed-up for 8 postoperative months, it was observed that the gracilis muscle flap was well-adapted to its place, gained a very good tonus, its volume reduced over time and reached to ideal dimensions, and the overlying skin graft provided a good color and texture match with the surrounding tissues. The motor activity of the muscle was monitored with the Tinel's test. The speech and facial expressions of the patient were very clear. Despite the patient has an edentulous mandible and was not using prosthesis, her feeding with fluid and solid foods was free of problems, oral competence was highly sufficient, and there was no any drooling. Esthetic appearance was very good and intraoral vestibular depth was sufficient. The mouth opening was 3 cm. When comparing with upper orbicularis oculi muscle on the electroneuromyography (ENMG) ordered at the 8th month, a similar nerve conduction time (3.3 versus 3.8 ms) and contraction amplitude (0.5 versus 0.4 mV) values were obtained from the gracilis muscle. Follow-up of the patient is still continued with no tumor recurrence observed during this period.Being the real dynamic flap and its tonus of the functional gracillis free muscle flap in opposite to the static methods provides a significant superiority over the other options in terms of oral functions; moreover, the overlying skin graft presents a very good color and texture harmony aesthetically. This method is a candidate to be an exclusive surgical technique in the repair of total or close to total lip losses in the future. PMID- 29461378 TI - Do You Have a Writing Mentor? PMID- 29461379 TI - Understanding Poverty: Teaching Social Justice in Undergraduate Nursing Education. AB - AIM: This article presents results of an exploratory qualitative study examining gains in empathy and social justice beliefs among undergraduate nursing students. BACKGROUND: As undergraduate nursing education provides the foundation for future forensic nurses, developing successful methods to increase beliefs and behaviors of social empathy and social justice among nursing students will have a beneficial effect on the specialty of forensic nursing. As such, a team of nursing researchers explored the effects of a poverty simulation on the social empathy and social justice beliefs held by undergraduate students. METHOD: The research team conducted an exploratory qualitative study of student reflective journals. Using an inductive interpretive process, the researchers performed a content analysis of student responses. RESULTS: The researchers identified three constitutive patterns and eight supporting themes as reflected in the students' reflective journals after participation in poverty simulation sessions. CONCLUSION: This research study found that, when nursing students participate in poverty simulation experiences, they gain an increased understanding of the vulnerability and complexities of living in poverty and are motivated to both advocate for patients and become change agents. APPLICATION: Such increases in social empathy and promotion of social justice will inevitably positively affect their future practice and inform their development as forensic nurses. PMID- 29461380 TI - What Does the Implementation of Peer Care Training in a U.K. Prison Reveal About Prisoner Engagement in Peer Caregiving? AB - The number of aging and chronically ill prisoners continues to rise within the United Kingdom prison demography; consequentially, many institutions face health and social care crises of immense proportions. The needs of this group are both complex and costly, and in the United Kingdom, this is set to a backdrop of overcrowding, increasing violence, and public spending cuts in line with government austerity targets. In this context, the development of prisoner peer caregiving is proposed as an approach to mitigating the effects of aging, disability, and illness. A qualitative study was implemented to design, deliver, and evaluate a peer care training intervention within a U.K. prison. The perceptions of six prisoner peer caregivers are represented in this article. Thematic analysis of interview transcripts identified challenges experienced by peer caregivers in practice as well as recommended practical solutions. The social processes underpinning prisoner peer caregiving are discussed, including individual and organizational impediments to the fulfillment of their role. Practice theory, social learning theory, and criminological sensitivities were used as theoretical lenses to analyze the findings. PMID- 29461381 TI - Cultural Humility: An Active Concept to Drive Correctional Nursing Practice. AB - Correctional nursing practice is focused on a unique patient population: inmates who present with their own ethnicities and have an imposed culture from the prison structure. As such, culture must be considered to provide holistic care. Madeleine Leininger's Theory of Culture Care Diversity and Universality, which maintains that care is the essence of nursing (without inclusion of culture, there is no care), suggests three nursing actions: to maintain the patient's culture, make accommodations for it, and/or repattern cultural ways that may be unhealthful. Given that correctional nurses work within the context (and culture) of custody, Leininger's nursing actions may not always be feasible; however, showing an underlying attitude of cultural humility is. In this article, cultural humility, the basis of culturally competent care, is described in a manner that can drive nursing practice in corrections. PMID- 29461382 TI - Factors That Influence Mandatory Child Abuse Reporting Attitudes of Pediatric Nurses in Korea. AB - PURPOSE: This study aimed to identify knowledge of child abuse, awareness of child abuse reporting, factors that influence attitudes toward mandatory reporting, and professionalism among a sample of pediatric nurses in Korea. METHODS: One hundred sixteen pediatric nurses working at two university hospitals in Korea took part in the study and completed self-administered questionnaires. The data were analyzed using descriptive statistics, t tests, analysis of variance, Pearson correlation coefficients, and hierarchical regression analysis. RESULTS: Knowledge of child abuse, awareness of child abuse reporting, and attitudes toward mandatory reporting were low. Regarding nursing professionalism, social perceptions had the lowest mean score and nursing autonomy had the highest mean score. Attitudes toward mandatory reporting significantly correlated with professionalism. In the hierarchical regression model, the influences of nursing autonomy and intentions to report child abuse on attitudes toward mandatory reporting were statistically significant (F = 2.176, p = .013), explaining 32% of the variation in attitudes toward mandatory reporting. CONCLUSION: The results of this study could be used to improve systems and policies addressing child abuse and to further develop reporting procedures for identifying children at risk of abuse, to ensure their protection as a professional responsibility.

PMID- 29461383 TI - Evaluating Nurse Practitioners Perceived Knowledge, Competence, and Comfort Level in Caring for the Sexually Abused Child. AB - OBJECTIVE: The purpose of this project was to evaluate nurse practitioners' (NPs') current approach and self-reported competence in the care of the sexually abused child in the primary care setting. METHODS: A 50-question survey was distributed to 5,734 NPs who were members of a state nursing organization and nursing alumni. Inclusion criteria included NPs caring for pediatric patients in a primary care setting in New York State. RESULTS: A total of N = 325 responses were obtained, and 110 participants met the inclusion criteria. Very few NPs felt competent to perform a medical forensic examination on a sexually abused child (25.5%), and even fewer felt competent to render a definitive opinion on sexual abuse (17.3%) or to testify in court (12.7%). Most NPs felt the need for more training on child sexual abuse (78.2%). Most would prefer to refer children who are suspected of sexual abuse to an expert (77.3%), but very few (19.1%) are being referred to a local resource, like a Child Advocacy Center when a parent calls the office with a concern. CONCLUSION: More research is needed to evaluate clinical practices regarding child sexual abuse. NPs see value in pursuing specialist referrals for child sexual abuse but do not have access to the appropriate resources or are unaware of the availability within their community. PRACTICE IMPLICATIONS: NPs should be aware of their own limitations and seek out education to improve their knowledge and skills. Forensic nurses are ideally situated to provide education on the available resources and the recommended clinical guidelines for referral.

AB - OBJECTIVE: We aimed to document the prevalence of cardiovascular disease (CVD) risk factors and symptoms in Quebec firefighters. METHODS: Seven hundred and seventy-nine (779) male firefighters (age: 41.6 +/- 10.4 years; body mass index [BMI]: 28.0 +/- 3.6 kg/m) answered an online questionnaire evaluating lifestyle and the presence of CVD risk factors and symptoms. RESULTS: The prevalence of obesity (BMI is more than or equal to 30 kg/m), diagnosed hypertension, diagnosed dyslipidemia, and diagnosed type 2 diabetes mellitus was respectively 23.6%, 12.2%, 17.4%, and 1.7%. Among survey participants, 34.5% were categorized as moderate and 43.6% as high CVD risk, according to American College of Sports Medicine guidelines. CONCLUSIONS: A high proportion of Quebec firefighters are at moderate to high risk of CVD. These findings suggest that Quebec fire departments should help all firefighters to adopt and maintain a healthy lifestyle. PMID- 29461387 TI - Organizational Wellness Program Implementation and Evaluation: A Holistic Approach to Improve the Wellbeing of Middle Managers. AB - : Employee wellness programs can provide benefits to institutions as well as employees and their families. Despite the attempts of some organizations to implement programs that take a holistic approach to improve physical, mental, and social wellness, the most common programs are exclusively comprised of physical and nutritional components. In this study, we implemented a wellness program intervention, including training using a holistic approach to improve the wellbeing of middle managers in several multinational organizations. We included control and experimental groups to measure wellness and teamwork with two repeated measures. Our results indicated that employees receiving the intervention had improved measures of wellness and teamwork. A positive relationship was found between wellness and teamwork in the experimental group when compared with the control group. Taken together, the data suggest that implementation of these programs would provide valuable outcomes for both employees and organizations.

AB - Bivalirudin (Angiomax; The Medicines Company, Parsippany, NJ), a direct thrombin inhibitor, has found increasing utilization as a heparin alternative in the pediatric population, most commonly for the treatment of thrombosis secondary to heparin-induced thrombocytopenia. Due to the relative rarity of heparin-induced thrombocytopenia as well as the lack of Food and Drug Administration-approved indications in this age group, much of what is known regarding the pharmacokinetics and pharmacodynamics of bivalirudin in this population has been extrapolated from adult data. This narrative review will present recommendations regarding the use of bivalirudin for procedural anticoagulation in the pediatric population based on the published literature. PMID- 29461392 TI - Combined Colloid Preload and Crystalloid Coload Versus Crystalloid Coload During Spinal Anesthesia for Cesarean Delivery: A Randomized Controlled Trial. AB - BACKGROUND: The optimal strategy of fluid administration during spinal anesthesia for cesarean delivery is still unclear. Ultrasonography of the inferior vena cava (IVC) has been recently used to assess the volume status and predict fluid responsiveness. In this double-blind, randomized controlled study, we compared maternal hemodynamics using a combination of 500-mL colloid preload and 500-mL crystalloid coload versus 1000-mL crystalloid coload. We assessed the IVC at baseline and at subsequent time points after spinal anesthesia. METHODS: Two hundred American Society of Anesthesiologists physical status II parturients with full-term singleton pregnancies scheduled for elective cesarean delivery under spinal anesthesia were randomly allocated to receive either 500-mL colloid preload followed by 500-mL crystalloid coload (combination group) or 1000-mL crystalloid coload (crystalloid coload group) administered using a pressurizer. Ephedrine 3, 5, and 10 mg boluses were administered when the systolic blood pressure decreased below 90%, 80% (hypotension), and 70% (severe hypotension) of the baseline value, respectively. The IVC was assessed using the subcostal long axis view at baseline, at 1 and 5 minutes after intrathecal injection, and immediately after delivery; the maximum and minimum IVC diameters were measured, and the IVC collapsibility index (CI) was calculated using the formula: IVC-CI = (maximum IVC diameter - minimum IVC diameter)/maximum IVC diameter. The primary outcome was the total ephedrine dose. RESULTS: Data from 198 patients (99 patients in each group) were analyzed. The median (range) of the total ephedrine dose was 11 (0-60) mg in the combination group and 13 (0-61) mg in the crystalloid coload group; the median of the difference (95% nonparametric confidence interval) was -2 (-5 to 0.00005) mg, P = .22. There were no significant differences between the 2 groups in the number of patients requiring ephedrine, the incidence of hypotension and severe hypotension, the time to the first ephedrine dose, and neonatal Apgar scores at 1 and 5 minutes. The maximum and minimum IVC diameters in each group increased after spinal anesthesia and after delivery, and they were larger in the combination group. The IVC-CI after delivery was higher in the crystalloid coload group. CONCLUSIONS: The combination of 500-mL colloid preload and 500-mL crystalloid coload did not reduce the total ephedrine dose or improve other maternal outcomes compared with 1000-mL crystalloid coload. The IVC was reliably viewed before and during cesarean delivery, and its diameters significantly changed over time and differed between the 2 groups. PMID- 29461393 TI - Neuraxial Anesthesia in Children With Ventriculoperitoneal Shunts. AB - Neuraxial anesthesia has been demonstrated to be safe and effective for children undergoing subumbilical surgery. There is limited evidence regarding the safety of neuraxial anesthesia in pediatric patients with a ventriculoperitoneal shunt. We evaluated a series of 25 patients with indwelling ventriculoperitoneal shunts for complications within 30 days of any procedure performed with a neuraxial technique. One patient required a ventriculoperitoneal shunt revision 5 days after a lumbar catheter placement. The neurosurgeon determined the revision to be likely unrelated to the patient's lumbar catheter. Concerns about the use of neuraxial anesthesia in patients with an indwelling ventriculoperitoneal shunt may be overstated. PMID- 29461394 TI - Diagnosis and Management of Polytraumatized Patients With Severe Extremity Trauma. AB - Multiply injured patients with severe extremity trauma are at risk of acute systemic complications and are at high risk of developing longer term orthopaedic complications including soft-tissue infection, osteomyelitis, posttraumatic osteoarthritis, and nonunion. It is becoming increasingly recognized that injury magnitude and response to injury have major jurisdiction pertaining to patient outcomes and complications. The complexities of injury and injury response that affect outcomes present opportunities to apply precision approaches to understand and quantify injury magnitude and injury response on a patient-specific basis. Here, we present novel approaches to measure injury magnitude by adopting methods that quantify both mechanical and ischemic tissue injury specific to each patient. We also present evolving computational approaches that have provided new insight into the complexities of inflammation and immunologic response to injury specific to each patient. These precision approaches are on the forefront of understanding how to stratify individualized injury and injury response in an effort to optimize titrated orthopaedic surgical interventions, which invariably involve most of the multiply injured patients. Finally, we present novel methods directed at mangled limbs with severe soft-tissue injury that comprise severely injured patients. Specifically, methods being developed to treat mangled limbs with volumetric muscle loss have the potential to improve limb outcomes and also mitigate uncompensated inflammation that occurs in these patients. PMID- 29461395 TI - Critical-Size Bone Defects: Is There a Consensus for Diagnosis and Treatment? AB - There is a significant burden of disease associated with bone defects, and their management is challenging. These injuries have a profound clinical and economic impact, and outcomes are limited by high rates of complication and reoperation, as well as poor functional outcomes. There remains a lack of consensus around definitions, reliable models, and best practices for the surgical management of bone defects. The current state of the literature on bone defects is reviewed here, with a focus on defining critical-size bone defect, the use of the induced membrane technique, the role of biologics, and the management of infected bone defects. PMID- 29461396 TI - Absolute Versus Relative Fracture Fixation: Impact on Fracture Healing. AB - The goals of all orthopaedic surgeons treating fractures are, and will remain, obtaining union of the fracture with a well-aligned and functional limb while minimizing the risk of complications. This requires us to understand how the biomechanical environment of the fracture affects healing and to be able to discern which mechanical environment is preferred over another. Understanding the spectrum of stability imparted by our current surgical devices is paramount to giving our patients the best opportunity to heal and recover from their injury. Gone are the simplistic views of plates and screws being applied for absolute stability and nails and external fixators being applied for relative stability. This review sheds new light on how the use of different implants provides the appropriate stability to encourage fracture healing and limit the risk of complication and loss of function. PMID- 29461397 TI - Biomechanics-Hot Topics Part I. AB - This study summarizes presentations of a symposium on biomechanically related hot topics of the 2015 Basic Science Focus Forum. Each topic emphasizes a biomechanical challenge common to all 4 of these presentations: an ideal fixation technique should deliver ample stability and sufficient flexibility to prevent fixation failure and to restore normal function. PMID- 29461398 TI - What Is Important Besides Getting the Bone to Heal? Impact on Tissue Injury Other Than the Fracture. AB - Fracture surgeons do a great job of managing bone issues, but they may overlook the associated soft tissue injuries that play a significant role in the final outcome after musculoskeletal injury. The soft tissue reconstruction ladder can help guide reconstructive procedures based on the least complex procedure that allows the best chance of fracture healing. Muscle injury, volume loss, and deconditioning occur with traumatic injury and during the recovery phase. Neuromuscular stimulation, nutrition, and strength training are potential ways to aid in recovery. Complex periarticular knee injuries have a high rate of associated soft tissue injuries that may affect outcome if associated with knee instability. Identifying and addressing these injuries can increase the likelihood of a good outcome. Articular cartilage loss can make articular reconstruction impossible. Large fresh osteoarticular allografts can be a reconstructive option. Addressing all the damaged structures involved with a fracture may be the next step in improving patient outcomes. PMID- 29461399 TI - How Does Orthopaedic Research Affect Patient Care? AB - Academic medicine hinges on high-quality results from research. Surgeon scientists spend their career acquiring grants, writing papers, and educating a next generation of scientists. The real question is how well are we at playing this game? Does our research change surgical practice or affect patient care or government policy? Ideally, published research does and will continue to shape the way care is delivered. Key questions remain, however; what is the return on research investment in orthopaedics? How can surgeons decide which "evidence" matters, and does practice-change only refer to Level I evidence (randomized trials)? This review considers all these questions. PMID- 29461400 TI - Biomechanics-Hot Topics Part II. AB - Orthopaedic surgery and biomechanics are intimately partnered topics in medicine. Biomechanical principles are used to design implants and fashion treatment protocols. Although it would seem that biomechanical principles in the design of fixation devices and fracture repair constructs have been already finalized, there are several points of controversy remaining. New technology has raised new questions, while at the same time, we still do not fully understand simple clinical principles such as time of fracture healing depending on the construct used. This review looks at several of these current controversies to better understand what work is needed in fracture care going forward. PMID- 29461401 TI - Outside the Bone: What Is Happening Systemically to Influence Fracture Healing? AB - This article summarizes presentations of a symposium on bone health-related hot topics of the 2016 Basic Science Focus Forum. Taken together, these topics emphasize the critical importance of bone health in fracture management, the systemic factors that influence fracture healing, and the need to focus on issues other than simply the technical aspects of fracture repair. PMID- 29461402 TI - Management of Mangled Extremities and Orthopaedic War Injuries. AB - In 16 years of conflict, primarily in Iraq and Afghanistan, wounded warriors have primarily been subjected to blast type of injuries. Evacuation strategies have led to unprecedented survival rates in blast-injured soldiers, resulting in large numbers of wounded warriors with complex limb trauma. Bone and soft tissue defects have resulted in increased use of complex reconstructive algorithms to restore limbs and function. In addition, in failed salvage attempts, advances in amputation options are being developed. In this review, we summarize state-of-the art limb-salvage methods for both soft tissue and bone. In addition, we discuss advances in diagnostic methods with development of personalized clinical decision support tools designed to optimize outcomes after severe blast injuries. Finally, we present new advances in osteointegrated prostheses for above-knee amputations. PMID- 29461403 TI - Fracture Healing Adjuncts-The World's Perspective on What Works. AB - Treatment of bone defects remains a challenging clinical problem. Despite our better understanding of bone repair mechanisms and advances made in microsurgical techniques and regenerative medicine, the reintervention rates and morbidity remain high. Surgical techniques such as allograft implantation, free vascularized fibular graft, distraction osteogenesis, loaded titanium cages, and the induced membrane technique continue to evolve, but the outcome can be affected by a number of parameters including the age of the patient, comorbidities, systemic disorders, the location of the defect, and the surgeon's preference and experience. In the herein article, a brief summary of the most currently used techniques for the management of bone defects is presented. PMID- 29461404 TI - Use of Patient-Related Outcomes After Orthopaedic Trauma: Helpful or Not So Much? AB - Over 100 years ago, the orthopaedic surgeon, Ernest Codman, recommended that surgeons and hospitals be paid by the "end result." Healthcare Reform is moving to value over volume, and patient-reported outcomes (PROs) are 1 measure of quality and outcomes that are becoming pervasive. In this study, the current status of patient-reported outcomes and their use in orthopaedic trauma was reviewed. The contributors presented the state of PRO measurements at the Basic Science Focus Forum at the OTA Annual Meeting in 2016. Information on the currently available PROs was presented and analyzed to determine whether they were adequate for research in orthopaedic trauma. PROs were then discussed in the context of which were the most appropriate for determining outcomes in trauma surgery. The concept of mobility as a validated PRO for an assessment of general health was then presented. The final topic was a summary of how PROs will be used by insurers and governmental agencies. These topics provide a comprehensive overview of the current state of PROs in the context of orthopaedic trauma. PMID- 29461405 TI - Principles of Nonunion Management: State of the Art. AB - A substantial proportion of fractures can present with nonunion, and the management of nonunion continues to present a challenge for orthopaedic surgeons. A variety of biological, mechanical, patient, and injury factors can contribute to the occurrence of nonunion, and often the cause of nonunion may be multifactorial. Successful management often requires assessment and treatment of more than one of these factors. This article reviews common factors that may contribute to nonunion including infection, impaired biology, and metabolic disorders. In addition, new and evolving strategies for diagnosing the cause and effectively treating nonunion including the diagnosis of infection, metabolic workup, bone grafting, cell-based therapies, and biological adjuvants are reviewed and discussed. PMID- 29461406 TI - Interventional Procedures Outside of the Operating Room: Results From the National Anesthesia Clinical Outcomes Registry. AB - OBJECTIVES: This study examines the impact of procedural locations and types of anesthetics on patient outcomes in non-operating room anesthesia (NORA) locations. The National Anesthesia Clinical Outcomes Registry database was examined to compare OR to NORA anesthetic complications and patient demographics. METHODS: The National Anesthesia Clinical Outcomes Registry database was examined for all patient procedures from 2010 to 2013. A total of 12,252,846 cases were analyzed, with 205 practices contributing information, representing 1494 facilities and 7767 physician providers. Cases were separated on the basis of procedure location, OR, or NORA. Subgroup analysis examined outcomes from specific subspecialties. RESULTS: NORA procedures were performed on a higher percentage of patients older than 50 years (61.92% versus 55.56%, P < 0.0001). Monitored anesthesia care (MAC) (20.15%) and sedation (2.05%) were more common in NORA locations. The most common minor complications were postoperative nausea and vomiting (1.06%), inadequate pain control (1.01%), and hemodynamic instability (0.62%). The most common major complications were serious hemodynamic instability (0.10%) and upgrade of care (0.10%). There was a greater incidence of complications in cardiology and radiology locations. Overall mortality was higher in OR versus NORA (0.04% versus 0.02%, P < 0.0001). Subcategory analysis showed increased incidence of death in cardiology and radiology locations (0.05%). CONCLUSIONS: NORA procedures have lower morbidity and mortality rates than OR procedures, contrary to some previously published studies. However, the increased complication rates in both the cardiology and radiology locations may need to be the target of future safety investigations. Providers must ensure proper monitoring of patients, and NORA locations need to be held to the same standard of care as the main operating room. Further studies need to identify at-risk patients and procedures that may predispose patients to complications. PMID- 29461407 TI - "The Jackson Table Is a Pain in the...": A Qualitative Study of Providers' Perception Toward a Spinal Surgery Table. AB - OBJECTIVE: The aim of this study was to define health care providers' perceptions toward prone patient positioning for spine surgery using the Jackson Table, which has not been hitherto explored. METHODS: We analyzed open-ended questionnaire data and interviews conducted with the spine surgical team regarding the current process of spinal positioning/repositioning using the Jackson Table. Participants were asked to provide an open-ended explanation as to whether they think the current process of spinal positioning/repositioning is safe for the staff or patients. Follow-up qualitative interviews were conducted with 11 of the participants to gain an in-depth understanding of the challenges and safety issues related to prone patient positioning. RESULTS: Data analysis resulted in 6 main categories: general challenges with patient positioning, role-specific challenges, challenges with the Jackson Table and the "sandwich" mechanism, safety concerns for patients, safety concerns for the medical staff, and recommendations for best practices. CONCLUSIONS: This study is relevant to everyday practice for spinal surgical team members and advances our understanding of how surgical teams qualitatively view the current process of patient positioning for spinal surgery. Providers recommended best practices for using the Jackson Table, which can be achieved through standardized practice for transfer of patients, educational tools, and checklists for equipment before patient transfer and positioning. This research has identified several important practice opportunities for improving provider and patient safety in spine surgery. PMID- 29461408 TI - Brimonidine Ophthalmic Solution 0.025% for Reduction of Ocular Redness: A Randomized Clinical Trial. AB - SIGNIFICANCE: The alpha2-adrenergic receptor agonist brimonidine has been reported to induce conjunctival blanching in cataract, strabismus, laser refractive, and filtration procedures. Clinicians are often faced with red eyes with no apparent underlying pathology. Low-dose brimonidine reduced ocular redness in such subjects with efficacy maintained over 1 month and negligible rebound redness. PURPOSE: The aim of this study was to evaluate the safety and efficacy of brimonidine tartrate ophthalmic solution 0.025% for the treatment of ocular redness. METHODS: In this single-center, double-masked, phase 3 clinical trial, adult subjects with baseline redness of more than 1 unit in both eyes (0- to 4-unit scale) were randomized 2:1 to brimonidine 0.025% or vehicle. A single dose was administered in-office (day 1); thereafter subjects instilled treatment four times a day for 4 weeks, with clinic visits on days 15, 29, and 36 (7 days post-treatment). Efficacy end points included investigator-evaluated redness 5 to 240 minutes post-instillation on day 1 (primary); investigator-evaluated change from baseline 1, 360, and 480 minutes post-instillation on day 1, and 1 and 5 minutes post-instillation on days 15 and 29; total clearance of redness, and subject-assessed redness. Safety/tolerability measures included adverse events, rebound redness, and drop comfort. RESULTS: Sixty subjects were randomized (n = 40 brimonidine, n = 20 vehicle). Investigator-assessed redness was lower with brimonidine versus vehicle over the 5- to 240-minute post-instillation period (mean [SE], 0.62 [0.076] vs. 1.49 [0.108]; P < .0001) and at each time point within that period (P < .0001). At 1, 360, and 480 minutes post-instillation, respectively, the mean differences (95% confidence interval) between treatments were -0.73 (-1.05 to -0.41), -0.57 (-0.84 to -0.29), and -0.39 (-0.67 to -0.10), respectively. No tachyphylaxis was evident with brimonidine on days 15 and 29, and minimal rebound redness was observed following discontinuation. Adverse events were infrequent, and brimonidine was rated as very comfortable. CONCLUSIONS: Brimonidine 0.025% appeared safe and effective for reduction of ocular redness, with an 8-hour duration of action, no evidence of tachyphylaxis, and negligible rebound redness. PMID- 29461409 TI - Repeatability of Monocular Acuity Testing in Adults with and without Down Syndrome. AB - PURPOSE: Individuals with Down syndrome may experience greater difficulty reliably performing visual acuity (VA) tests because of intellectual disability and limitations in visual quality. This study evaluated the repeatability of acuity (Bailey-Lovie [BL] and HOTV) in subjects with and without Down syndrome. METHODS: High-contrast VA was measured in both eyes of 30 subjects with Down syndrome (mean, 30 years; range, 18 to 50 years) and 24 control subjects without Down syndrome (mean, 29 years; range, 18 to 50 years). In the Down syndrome group, 23 subjects performed BL, and 7 subjects performed HOTV. All control subjects performed both BL and HOTV, but for HOTV analysis, only seven age matched control subjects were included. For each eye, subjects performed VA three times on different charts (computer controlled, single-line display) until five total letters were missed on each chart. A repeated-measure ANOVA was used to compare the acuity measures between groups. RESULTS: The average logMAR VA for subjects with Down syndrome was approximately six lines worse than the control subjects (BL: Down syndrome = right eye: 0.51 +/- 0.16, left eye: 0.53 +/- 0.18; control = right eye: -0.06 +/- 0.06, left eye: -0.06 +/- 0.08, P < .0001; HOTV: Down syndrome = right eye: 0.47 +/- 0.19, left eye: 0.46 +/- 0.16; control: right eye = -0.11 +/- 0.09, left eye: -0.07 +/- 0.07, P < .001). Bailey-Lovie VA repeatability (1.96 * Sw * ?2) was 0.13 logMAR (6.5 letters) for Down syndrome and 0.09 logMAR (4.5 letters) for control subjects. HOTV VA repeatability was 0.16 logMAR (eight letters) for both Down syndrome and control subjects. CONCLUSIONS: Despite poorer acuity in individuals with Down syndrome, repeatability of VA measurements was comparable to control subjects for both BL and HOTV techniques. PMID- 29461411 TI - Sequencing effects of object control and locomotor skill during Integrated Neuromuscular Training in 6-7 year old children. AB - This study examined whether scheduling of object control (e.g., throwing, catching) and locomotor skills (e.g., running, jumping), within an integrated neuromuscular training (INT) program, results in different responses in motor competence, muscular fitness and perceived motor competence in 6-7 year old children. Seventy seven boys and 63 girls (n = 140) from 3 primary schools were randomised into three, 10-week interventions, Loco First (n = 50) where locomotor skills were performed first followed by object control skills; Object First (n =48) where object control skills were performed first followed by locomotor skills or a control group (n =42, CON) who undertook school Physical Education. Results indicated greater total motor competence in Loco First and Object First vs CON (P = 0.001) with the increases in motor competence being greater for Object First vs Loco First (P = 0.001). Sprint speed (10m) was lower for Object First vs CON (P = .024). Standing long jump distance was greater in Loco First vs CON (P .0001) and Object First (P = .0001). Seated medicine ball throw distance was greater for Loco First and Object First vs CON (Both P = .001). Perceived motor competence was also higher for Object First vs Loco First (P = .005) and CON (P = .001). This study suggests that scheduling object control skills before locomotor skills within school-based strength and conditioning has a greater effect on motor competence, muscular fitness and perceived motor competence in 6 7 year old children. PMID- 29461410 TI - Impact of Cognitive Demand during Sustained Near Tasks in Children and Adults. AB - SIGNIFICANCE: These results demonstrate that accommodation in children is more accurate and less variable when performing a sustained near task with increased cognitive demand. In addition, children with increased uncorrected hyperopia have less stable accommodative responses, which may have visual implications during sustained near tasks. PURPOSE: This study investigated accommodative accuracy (lag) and variability during sustained viewing for passive and active tasks in children and adults with emmetropia and uncorrected hyperopia. METHODS: Lag and variability (root mean square [RMS] and low-frequency component) were measured in 54 children aged 3 to younger than 10 years with mean spherical equivalent of +1.31 +/- 1.05 diopters (D) (range, -0.37 to +4.58 D) and 8 adults aged 22 to 32 years with mean spherical equivalent +0.65 +/- 0.62 D (range, -0.13 to +1.15 D). Subjects viewed 20/50 stimuli at 33 cm during both a 10-minute passive and active task. Group 1 (<6 years or nonreaders) viewed shapes; group 2 (>=6 years and reading) and adults read passages. RESULTS: Groups 1 and 2 had larger lags, RMS, and low-frequency component for passive versus active tasks (P < .001). Lag and RMS did not differ between tasks in adults (P > .05), but low-frequency component was larger during passive viewing (P = .04). Group 1 had significantly higher RMS and low-frequency component than group 2 and the adults in the passive condition had greater low-frequency component in the active condition. In children, hyperopia was independently associated with RMS and low-frequency component under passive (RMS 95% confidence interval [CI], 0.04 to 0.15; low-frequency component 95% CI, 0.00011 to 0.00065) and active (RMS 95% CI, 0.001 to 0.06; 95% CI, 0.000014 to 0.00023) viewing. CONCLUSIONS: Accommodation is more accurate and less variable when children are engaged in the task. Children also have more variable accommodation than adults. In addition, children with greater hyperopia have more variable accommodation during sustained near tasks. PMID- 29461412 TI - The Effect of Augmented Feedback Type and Frequency on Velocity-Based Training Induced Adaptation and Retention. AB - The purpose of this study was to compare the benefits of 4-weeks of velocity based training (VBT) using different augmented feedback (AugFb) types and the frequency of AugFb, and whether adaptations are retained 10 days post-training. Thirty-seven collegiate male rugby players were divided into groups that received immediate-feedback (ImFb; n=9), visual-feedback (ViFb; n=10), average-feedback (AvgFb; n=10) and no-feedback (NoFb; n=8) during each VBT session consisting of 3 sets of 5 repetitions of loaded jump squats. The ImFb group received AugFb regarding lifting velocity under loaded jump squats (LV-JS) following every jump, whereas LV-JS measures were averaged following each set of jumps and presented to the AvgFb group. The loaded jump squats were video-recorded and displayed as kinematic feedback for the ViFb group following each set, although no feedback was provided for the NoFb group. LV-JS measures were reported at baseline, during each training session and 10-days post training. LV-JS measures were significantly greater for the ImFb Group compared to the other groups during a number of post-baseline time points (P<0.05). Furthermore, at 4-weeks of VBT and 10 days post-retention, effect size (ES) calculations showed that LV-JS measures were greater with moderate to large effects for the ImFb group compared to the NoFb (ES=1.02-1.25), AvgFb (ES=0.78-0.82) and ViFb (ES=0.74-1.60), respectively. However, LV-JS measures were reduced with moderate to large effects 10 days post retention for the ViFb (ES=-0.60) and NoFb (ES=-0.85) groups. Providing LV-JS feedback following each jump appears to optimize performance and should be considered as a training tool during VBT. PMID- 29461413 TI - Cardiac-Autonomic Responses to In-Season Training Among Division-1 College Football Players. AB - Despite having to endure a rigorous in-season training schedule, research evaluating daily physiological recovery status markers among American football players is limited. The purpose of this study was to determine if recovery of cardiac-autonomic activity to resting values occurs between consecutive-day, in season training sessions among college football players. Subjects (n = 29) were divided into groups based on position: receivers and defensive backs (SKILL, n = 10); running backs, linebackers and tight-ends (MID-SKILL, n = 11) and linemen (LINEMEN, n = 8). Resting heart rate (RHR) and the natural logarithm of the root mean square of successive differences multiplied by twenty (LnRMSSD) were acquired at rest in the seated position prior to Tuesday and Wednesday training sessions and repeated over three weeks during the first month of the competitive season. A position * time interaction was observed for LnRMSSD (p = 0.04), but not for RHR (p = 0.33). No differences in LnRMSSD between days was observed for SKILL (Tuesday = 82.8 +/- 9.3, Wednesday = 81.9 +/- 8.7, p > 0.05). Small reductions in LnRMSSD were observed for MID-SKILL (Tuesday = 79.2 +/- 9.4, Wednesday = 76.2 +/- 9.5, p < 0.05) and LINEMEN (Tuesday = 79.4 +/- 10.5, Wednesday = 74.5 +/- 11.5, p < 0.05). The individually averaged changes in LnRMSSD from Tuesday to Wednesday were related to PlayerLoad (r = 0.46, p = 0.02) and body mass (r = -0.39, p = 0.04). Cardiac-parasympathetic activity did not return to resting values for LINEMEN or MID-SKILL prior to the next training session. Larger reductions in LnRMSSD tended to occur in players with greater body mass despite having performed lower workloads, though some individual variability was observed. These findings may have implications for how coaches and support staff address training and recovery interventions for players demonstrating inadequate cardiovascular recovery between sessions. PMID- 29461414 TI - Validity and Reliability of an on-Court Fitness Test for Assessing and Monitoring Aerobic Fitness in Squash. AB - Current on-court assessments of aerobic fitness in squash are not designed to yield a wealth of physiological data. Moreover, tests may require complex computer equipment or involve simulated racket strokes, which are difficult to standardize at high intensities. This study investigated the validity and reliability of a squash-specific fitness test which can yield both a standalone performance score, as well as pertinent physiological markers such as V[Combining Dot Above]O2max, the lactate turnpoint and oxygen cost, in a sport-specific environment. Eight national squash players completed three tests in a counter balanced order; an incremental laboratory treadmill test (LAB) and two on-court fitness tests (ST) that involved repeated shuttle runs at increasing speeds. V[Combining Dot Above]O2max during ST was agreeable with LAB (Typical error [TE]=3.3 mL.kg.min, r=0.79). The mean bias between LAB and ST was 2.5 mL.kg.min. There were no differences in maximum heart rate, post exercise blood lactate concentration or end of test RPE between LAB and ST (p>0.05). The ST was highly reliable, with 74 (10) laps completed in ST1 and 75 (12) laps in ST2 (mean bias=1 lap, TE=3 laps, r=0.97). Physiological markers were also reliable, including V[Combining Dot Above]O2max, (TE=1.5 mL.kg.min, r=0.95), the lap number at 4 mMol (TE=4 laps, r=0.77) and average VO2 across the first 4 stages (TE=0.94 mL.kg.min, r=0.95). We observed good agreement between LAB and ST for assessing V[Combining Dot Above]O2max and between both on-court trials for assessing test performance and selected physiological markers. Consequently, we recommend this test for monitoring training adaptations and prescribing individualized training in elite squash players. PMID- 29461415 TI - The Relationship Between Maximal Aerobic Power and Recovery in Elite Ice Hockey Players During a Simulated Game. AB - This project investigated whether there was a relationship between maximal aerobic power and the recovery or performance in elite ice hockey players during a simulated hockey game. An on-ice protocol was used to simulate a game of ice hockey. Recovery values were determined by the differences in lactate and heart rate measures. Total distance traveled was also recorded as a performance measure. On two other days, subjects returned and completed a maximal aerobic power test on a treadmill and a maximal lactate test on ice. Statistical analysis showed no relationship between maximal aerobic power or maximal lactate values and recovery (heart rate, lactate) or the performance measure of distance traveled. It was concluded there was no relationship between maximal aerobic power and recovery during a simulated game in elite hockey players. PMID- 29461416 TI - Relationship Between Physiologic Tests, Body Composition Changes, and On-Ice Playing Time in Canadian Collegiate Hockey Players. AB - Delisle-Houde, P, Chiarlitti, NA, Reid, RER, and Andersen, RE. Relationship between physiologic tests, body composition changes, and on-ice playing time in canadian collegiate hockey players. J Strength Cond Res 32(5): 1297-1302, 2018 Hockey player's body composition and physical fitness are suggested to influence coaching decisions regarding on-ice playing time. The purpose of this study was to explore the relationship between seasonal body composition changes, off-ice preseason testing, and on-ice metrics. Twenty-one Canadian collegiate hockey players (22.70 +/- 1.30 years old, 181.0 +/- 5.92 cm, 86.52 +/- 6.41 kg) underwent off-ice physical testing at the beginning of their season and had one total body dual energy x-ray absorptiometry scan at the beginning and end of the season. The team's statistician tracked all on-ice metrics. Pearson correlations were used to explore relationships between off-ice tests (long jump, vertical jump, beep test, and Wingate test), change in body composition (body fat percentage, visceral adiposity, and total lean tissue mass), and on-ice performance (average time on ice, average shift length, power play time, penalty kill time, and shot differential). Long jump was correlated with shot differential (r = -0.532, p <= 0.05) and average shift length (r = -0.491, p <= 0.05) while fatigue index was correlated with average ice time (r = -0.476, p <= 0.05). Hockey performance is a complex interaction of player's body compositions and skeletal fitness that interact to affect on-ice playing metrics.

AB - The purpose of the present study was to determine whether overlap (redundancy) exists between individual tests in a comprehensive strength testing protocol used after anterior cruciate ligament (ACL) reconstruction surgery. If overlap is present, one or more components of the protocol could potentially be omitted to make the testing protocol more efficient, but without compromising the usefulness of the testing.Sixty-nine patients (46M, 23F; mean age 28Y) were strength tested at 6 and 12 months after ACL reconstruction as part of a prospective cohort study. The following knee flexor and extensor strength tests were performed: isokinetic concentric strength at 60 degrees /s and 180 degrees /s, isokinetic eccentric strength at 60 degrees /s, and isometric knee flexor strength at 60 degrees flexion. Peak and average torque values were extracted and the ratio between the operated and non-operated limb calculated as a limb symmetry index. Overlap of strength tests was investigated by fitting a linear regression model to the data with an R threshold of 0.56 used as an indication of overlap.Overlap between peak and mean torque was present for extensor and flexor concentric and eccentric measurements at 12 months and for concentric measurements at 6 months. Peak torque measurements were therefore used for subsequent analysis. Concentric extensor peak torque at 60 degrees /s and 180 degrees /s showed overlap at 6 months (R = 0.73) but not at 12 months (R = 0.37). No other overlap was identified.In conclusion, there is little room for omission of individual strength testing protocol components due to the lack of overlap between tests. Isometric, eccentric and concentric tests may all provide unique information and all therefore should be considered for inclusion. PMID- 29461418 TI - Influence of biological maturity on the match performance of 8 to 16 year old elite male youth soccer players. AB - The aim of this study was to examine the influence of biological maturity on match performance in elite youth male soccer players. The participants were 80 Premier League Academy outfield players (8-16 years old). Biological maturity was determined by calculating estimated chronological age at peak height velocity. The U9 and U10 squads played 6-a-side and the U11-U16 squads played 11-a-side inter-academy matches. All matches were analyzed using a 1 Hz Global Positioning System (SPI elite, GPSport, Australia) with squad specific speed zones which were calculated based on 5 m flying sprint speed in the last 5 m of 10 m sprint test. In the U9/U10s, earlier maturers were given a longer pitch time by coaches (~4 min per match, p = 0.029) and covered a greater total distance (~9%, ~400 m, p = 0.037) and a greater distance by walking (~13%, ~100 m, p = 0.024) and jogging (~12%, ~200 m, p = 0.014) during a match compared to later maturers. In the U13/U14s, earlier maturers covered a greater distance per hour of a match by high speed running compared to later maturers (~25%, ~130 m, p = 0.028) and spent a longer percentage of time in high speed running during a match compared to later maturers (3.4% vs. 2.7%, p = 0.034). Thus, coaches should take care to provide all players with a similar pitch-time and should be aware in the talent identification and development process, particularly with the U13/U14 age group, that maturity can influence high speed match running performance. PMID- 29461419 TI - Morphological and physical fitness profile of young female sprint kayakers. AB - Traditionally, physical and anthropometrical profiles of the most successful kayak athletes have been identified in male kayakers. This study attempted to identify the differences in morphology and fitness level of two performance-based groups of young elite female paddlers. Eighty-six female kayakers, aged 13.62 +/- 0.57 years (mean +/- SD) were allocated in two groups (Top-10 and Rest) depending on their ranking in the three Olympic distances (200, 500 and 1000 meters). All subjects underwent a battery of anthropometrical (heights, weight, girths and sum of skinfolds), physical fitness (overhead medicine ball throw, countermovement jump, sit-and-reach test and 20-m multistage shuttle run test) and specific performance assessments (200, 500 and 1000 meters). Best paddlers presented significantly greater anthropometrical values in muscle mass percentage, maturity status and chronological age (p < 0.05) whereas physical fitness comparison only revealed significant differences in countermovement jump (p < 0.05). Furthermore, aerobic power and muscle mass percentage appear to be crucial in achieving optimal performances at long (1000-m) and short duration races (200 and 500-m). These findings confirm the importance of a larger and compact morphology, as well as superior fitness level, for success in female kayakers. The current results not only identify the weak areas on body composition and physical fitness depending on the maturity status but also the development of specific training programs for FEMALES. PMID- 29461420 TI - The effect of ibuprofen on muscle, hematological and renal function, hydric balance, pain, and performance during intense long-distance running. AB - The aim of this study was to investigate the effect of prophylactic use of nonsteroidal anti-inflammatory drugs (NSAID, i.e. Ibuprofen) on physical performance, vertical jump, muscle biomarkers, liver, kidney, acute pain and hydration status of participants in the 42 km Trail Running Challenge, a long distance race integrated over mountain routes. The sample consisted of 20 males randomly divided into two groups: a control group (CG) and an experimental group (EG) with 12 completing the race (41.1+/-8.8 y; 75.7+/-12.1 kg) and included in the final analysis. The EG were administered an ibuprofen capsule (400 mg) fifteen minutes before the beginning of the race, and again after 5 hours of racing if the route was not yet complete. There were significant time main effects for creatine kinase (CK) (p=0.001; f Cohen=0.25), lactate dehydrogenase (LDH) (p<0.001; f Cohen=2.05), aspartate aminotransferase (AST) (p=0.002; f Cohen=1.53), creatinine (p=0.002; f Cohen=2.24), urea (p=0.001; f Cohen=2.25), heart rate (HR) (p<0.001; f Cohen=4.88) and pain scores (p<0.001; f Cohen=1.93) which all increased during the race. There was a group * time interaction for squat jump (SJ) which significantly decreased in only the CG (p= 0.045; f Cohen=2.17). This may have been related to increased frequency of pain reported after the race in the gastrocnemius of the CG compared to the EG (p<0.05). It was concluded that ibuprofen intake did not reduce muscle damage during the competition but maintained leg muscular power performance (i.e. vertical jump), possibly by reducing gastrocnemius muscle pain. PMID- 29461421 TI - Tethered Swimming Test: Reliability and the Association to Swimming Performance and Land-based Anaerobic Performance. AB - The purpose of this study was three-fold: (a) to examine the test-retest reliability of a 30 second maximal tethered freestyle swimming test (TST), (b) to assess the validity of the TST by examining the association to sprint swimming performance and, (c) to examine the associations between a swim-specific and land based measure of anaerobic performance. A total of twenty-nine male and female swimmers were recruited to participate in the study. Each participant completed a Wingate Anaerobic cycling test (WAnT), two or four TST, and a 22.9 meter (25 yard), 45.7 meter (50 yard), and 91.4 meter (100 yard) maximal freestyle performance swims (PS). Mean and peak force (Fmean, Fpeak) were recorded for both the WAnT and TST, and average swimming velocity and time were recorded for the PS. Additionally, physiological and perceptual measures were recorded immediate post exercise for all tests. The results of the present investigation showed strong intersession and intrasession reliability (R= 0.821-0.975; p<0.001) for force parameters of the TST. Moderate correlations were found between Fmean and PS time and velocity of all distances, with slightly weaker correlations between Fpeak and the 22.9 meter (time and velocity) and 45.7 meter (velocity) PS. Finally, moderate correlations were found for Fmean and Fpeak of the TST and WAnT. This study demonstrated that the TST is a reliable measure, with moderate association to swimming performance, producing similar physiological responses compared to free swimming. Therefore, future research shoulSd focus on investigating the potential benefits of utilizing the TST as a regular assessment tool as a part of a competitive swimming training program to track adaptations and inform training decisions. PMID- 29461422 TI - Eight Weeks of Strength and Power Training Improves Club Head Speed in Collegiate Golfers. AB - Club head speed (CHS) is a major determinant of drive distance, a key component of golf performance. The purpose of this study was to determine the indirect effects of an eight-week strength and power program on CHS. Twelve (6 male, 6 female) NCAA Division II golfers (20.3+/-1.5 years) randomly assigned to an intervention or control group, underwent either a periodized strength and power program consisting of high-load barbell movements or a bodyweight and rotational movement focused resistance training program. Outcomes were CHS, countermovement jump (CMJ) height, and 1RM back squat (BS), power clean (PC), and deadlift (DL). Dependent t-tests were utilized to assess differences in outcome variables pre-to post for each group, independent t-tests were utilized to assess differences between groups, and Pearson correlations were utilized to assess associations between CHS and outcome variables. On average, the intervention group experienced improvements in all outcome variables except peak CHS (p=0.60); the control group displayed no changes in any outcome variable except a decrease in average CHS (p=0.028). Compared to the control group, the intervention group experienced greater improvements in average CHS, BS, PC, and average and peak CMJ height (p<0.05). Additionally, CHS had large associations with PC (r=0.70, p=0.012), BS (r=0.64, p=0.025), DL (r=0.54, p=0.068) and CMJ (r=0.73, p=0.007). These results suggest improving muscular strength and power by increasing PC, BS, and CMJ is associated with increased CHS in collegiate golfers. Integrating a high-load, barbell-focused strength and power program may be beneficial for improving CHS and indirectly, golf performance. PMID- 29461423 TI - The effect of short and long term aerobic training years on systemic O2 utilization, and muscle and prefrontal cortex tissue oxygen extraction in young women. AB - This study aimed to determine if systemic O2 utilization (V[Combining Dot Above]O2) and tissue oxygen extraction (deoxyhemoglobin [HHb]) in the vastus lateralis (VL), gastrocnemius (GAST) and pre-frontal cortex (PFC) were different during exercise between short-term trained (STT 6 - 24 months) and long-term trained (LTT > 5 yr) young women while controlling for current training load. Thirteen STT and 13 LTT participants completed ramp incremental (RI) and square wave constant load (SWCL) tests on a cycle ergometer. In LTT compared to STT: (i) V[Combining Dot Above]O2 was higher during the RI (p = 0.024) and SWCL (p = 0.001) tests; (ii) HHb in the VL (p = 0.044) and GAST (p = 0.027) was higher in the RI test; and (iii) there were significant group x intensity interactions for V[Combining Dot Above]O2 in the SWCL test. The additional years of aerobic training in LTT compared to STT (LTT 7.1 +/- 1.9 vs STT 1.5 +/- 0.4 yr) resulted in higher V[Combining Dot Above]O2, and HHb in the VL and GAST. These results indicate that in young women, independent of current training load, systemic V[Combining Dot Above]O2 and peripheral muscle O2 extraction during exercise continues to increase beyond 24 months of aerobic training.

PMID- 29461425 TI - Antibodies and the brain: antiribosomal P protein antibody and the clinical effects in patients with systemic lupus erythematosus. AB - PURPOSE OF REVIEW: Analysis of antiribosomal P protein autoantibodies (anti-P) pathogenicity in diffuse brain manifestations of neuropsychiatric lupus, emphasizing cognitive dysfunction and the recently emerged role of cross-reacting neuronal surface P antigen (NSPA) in alpha-amino-3-hydroxy-5-methyl-4 isoxazolepropionic acid and N-Methyl-D-Aspartate receptor glutamatergic transmission. RECENT FINDINGS: Circulating anti-P antibodies associate with executive planning dysfunction and attention impairments in lupus patients and perturb glutamatergic transmission through NSPA in mice hippocampus, translating into impaired synaptic plasticity and spatial memory. Planning impairment impacts quality of life. SUMMARY: In addition to the known association with lupus psychosis, new clinical and experimental evidence reveal a pathogenic role of anti-P antibodies in cognitive dysfunction, mechanistically explained by the anti P interaction with NSPA as a target involved in glutamatergic synaptic plasticity. PMID- 29461426 TI - Emergent management of primary headache: a review of current literature. AB - PURPOSE OF REVIEW: The current article reviews recent data on treatment of acute headache patients in the acute care setting. RECENT FINDINGS: Intravenous fluid hydration, a common component of emergency department (ED) migraine therapy, does not improve pain outcomes and leads to longer ED lengths of stay. Therefore, intravenous fluids should be administered only to migraine patients with clinical evidence of dehydration. Similarly, intravenous ketamine has garnered interest as a treatment for acute pain but does not provide substantial relief to migraine patients. New studies on the serotonin (5-HT3; 5-hydroxytryptamine-3) antagonist granisetron, intranasal lidocaine, and high-flow oxygen have reported conflicting results for migraine patients. Finally, although experts recommend avoiding opioids in migraine treatment, opioid administration remains prevalent in the ED. A new study has demonstrated that patients who receive intravenous hydromorphone in the ED are much less likely to attain acute headache relief. Standardized headache protocols may decrease opioid use and provide significant pain relief for patients. SUMMARY: Recent data have clarified the role of opioids and ketamine in the ED (do not use!). The role of treatment protocols and intravenous fluids is still ill-defined. Subpopulations of migraine patients may benefit from high-flow oxygen and intranasal lidocaine. PMID- 29461427 TI - Educational Effectiveness of an Easily Made New Simulator Model for Ultrasound Guided Vascular Access and Foreign Body Management Procedures on Pediatric Patients. AB - OBJECTIVES: This study aimed to introduce an easily made chicken breast simulator for ultrasound (US)-guided vascular access, foreign body (FB) detection, and hydrodissection in pediatric patients and to validate the effectiveness for training using this phantom tissue model. METHODS: The authors made the tissue phantom simulator using a chicken breast and rubber tourniquet for vascular access and fragments of a tongue blade and steel clip for FB detection and hydrodissection using a very simple method. We provided training on US-guided vascular access (following the tip [FTT] method), FB detection, and hydrodissection using this model for novice physicians to learn US-guided procedures for pediatric patients. In addition, we provided a questionnaire to solicit their thoughts on their knowledge and confidence to perform these procedures before and after training and to learn their thoughts on the similarity to actual patients and usefulness of this model on a 10-point Likert scale. RESULTS: A total of 16 emergency residents participated in this study. We obtained US images during vascular access (FTT) and FB detection/ hydrodissection procedures using this phantom tissue model. Residents' knowledge of and confidence to perform US-guided FTT method and FB detection/hydrodissection procedures after training increased to a statistically significant degree (P < 0.001 in all items). The median Likert scores regarding the similarity to actual patients and usefulness of this model were 8.5 (interquartile range, 7.5-9) and 10 (interquartile range, 8-10), respectively. CONCLUSIONS: The model for US guided procedures used in this study can be constructed by simple and easy methods, presents realistic procedural images, and was useful for training novice physicians to conduct US-guided procedures on pediatric patients. PMID- 29461428 TI - Cervical Spine Imaging and Injuries in Young Children With Non-Motor Vehicle Crash-Associated Traumatic Brain Injury. AB - OBJECTIVES: The aim of this study was to evaluate cervical magnetic resonance imaging (MRI) and computed tomography (CT) practices and cervical spine injuries among young children with non-motor vehicle crash (MVC)-associated traumatic brain injury (TBI). METHODS: We performed a retrospective study of a stratified, systematic random sample of 328 children younger than 2 years with non-MVC associated TBI at 4 urban children's hospitals from 2008 to 2012. We defined TBI etiology as accidental, indeterminate, or abuse. We reported the proportion, by etiology, who underwent cervical MRI or CT, and had cervical abnormalities identified. RESULTS: Of children with non-MVC-associated TBI, 39.4% had abusive head trauma (AHT), 52.2% had accidental TBI, and in 8.4% the etiology was indeterminate. Advanced cervical imaging (CT and/or MRI) was obtained in 19.1% of all children with TBI, with 9.3% undergoing MRI and 11.7% undergoing CT. Cervical MRI or CT was performed in 30.9% of children with AHT, in 11.7% of accidental TBI, and in 10.7% of indeterminate-cause TBI. Among children imaged by MRI or CT, abnormal cervical findings were found in 22.1%, including 31.3% of children with AHT, 7.1% of children with accidental TBI, and 0% of children with indeterminate cause TBI. Children with more severe head injuries who underwent cervical imaging were more likely to have cervical injuries. CONCLUSIONS: Abusive head trauma victims appear to be at increased risk of cervical injuries. Prospective studies are needed to define the risk of cervical injury in children with TBI concerning for AHT and to inform development of imaging guidelines. PMID- 29461429 TI - Hospital Variation in Risk-Adjusted Pediatric Sepsis Mortality. AB - OBJECTIVES: With continued attention to pediatric sepsis at both the clinical and policy levels, it is important to understand the quality of hospitals in terms of their pediatric sepsis mortality. We sought to develop a method to evaluate hospital pediatric sepsis performance using 30-day risk-adjusted mortality and to assess hospital variation in risk-adjusted sepsis mortality in a large state-wide sample. DESIGN: Retrospective cohort study using administrative claims data. SETTINGS: Acute care hospitals in the state of Pennsylvania from 2011 to 2013. PATIENTS: Patients between the ages of 0-19 years admitted to a hospital with sepsis defined using validated International Classification of Diseases, Ninth revision, Clinical Modification, diagnosis and procedure codes. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: During the study period, there were 9,013 pediatric sepsis encounters in 153 hospitals. After excluding repeat visits and hospitals with annual patient volumes too small to reliably assess hospital performance, there were 6,468 unique encounters in 24 hospitals. The overall unadjusted mortality rate was 6.5% (range across all hospitals: 1.5-11.9%). The median number of pediatric sepsis cases per hospital was 67 (range across all hospitals: 30-1,858). A hierarchical logistic regression model for 30-day risk adjusted mortality controlling for patient age, gender, emergency department admission, infection source, presence of organ dysfunction at admission, and presence of chronic complex conditions showed good discrimination (C-statistic = 0.80) and calibration (slope and intercept of calibration plot: 0.95 and -0.01, respectively). The hospital-specific risk-adjusted mortality rates calculated from this model varied minimally, ranging from 6.0% to 7.4%. CONCLUSIONS: Although a risk-adjustment model for 30-day pediatric sepsis mortality had good performance characteristics, the use of risk-adjusted mortality rates as a hospital quality measure in pediatric sepsis is not useful due to the low volume of cases at most hospitals. Novel metrics to evaluate the quality of pediatric sepsis care are needed. PMID- 29461430 TI - Quantitative Imaging and Imaging Biomarkers: The Search for Generalizability in Radiology.

A Comparison Study of Certified and Noncertified Nurse Educators. AB - AIM: The purpose of this study was to examine differences in how certified nurse educators and noncertified nurse educators valued nurse educator certification. BACKGROUND: No studies have investigated the differences in perceptions of certified and noncertified nurse educators. Understanding these differences may influence how the nursing profession recognizes and promotes excellence within the academic nursing specialty. METHOD: Perceived Value of Certification Tool Nurse Educator and demographic survey were administered via a web-based survey to a national sample of nursing faculty. RESULTS: Certified nurse educators valued certification with greater agreement than noncertified nurse educators. Personal accomplishment, personal satisfaction, and validation of knowledge were identified as the greatest rewards to certification. CONCLUSION: Nurse educators identified with intrinsic rewards of certification. Despite overall positive perceptions of nurse educator certification, strategies focused on extrinsic rewards may be necessary to increase certification rates. Such strategies may help overcome factors preventing educators from attaining certification. PMID- 29461434 TI - The Nursing Dean Role: An Integrative Review. AB - AIM: The aim of this integrative review was to appraise research on the uniqueness of the nursing dean role. BACKGROUND: Deans of nursing are challenged with multiple expectations of their role, which is unlike that of other deans in academia. Investigation is needed to understand what is entailed in being a dean of nursing. METHOD: This integrative review explores the role of the nurse dean utilizing a model described by Whittemore and Knafl. Their strategy uses a five step process of problem identification, literature search, data evaluation, data analysis, and presentation. RESULTS: Nursing deans are expected to excel in areas of education, the health care system, and relationships with the community stakeholders while navigating challenges of limited funding and a nationwide faculty shortage. CONCLUSION: This integrative literature review was an initial step toward the collective understanding of the nursing dean role. PMID- 29461435 TI - Types of Faculty Incivility as Viewed by Students in Bachelor of Science in Nursing Programs. AB - BACKGROUND: Faculty incivility can negatively affect student learning outcomes and safe clinical performance, yet little is known about the types of faculty incivility experienced by students. AIM: The aim of this qualitative descriptive study was to describe common types of incidents of faculty incivility as reported by students enrolled in traditional bachelor of science in nursing programs. MEHTOD: Qualitative descriptive methods were used to analyze the narratives of 30 students who had experienced incidents of faculty incivility. RESULTS: A typology explicating the different ways students perceive faculty to be uncivil included six categories: judging or labeling students, impeding student progress, picking on students, putting students on the spot, withholding instruction, and forcing students into no-win situations. CONCLUSION: Nursing faculty and administrators can use the incident typology to guide discussions related to detecting, assessing, and preventing incivility in nursing education.

AB - AIM: The aims of this study were to determine self-directed learning and time management skills of undergraduate nursing students and to investigate the relationship between the concepts. BACKGROUND: The use of self-directed learning has increased as an educational strategy in recent years. METHOD: This descriptive and correlational study was conducted with 383 undergraduate nursing students in Turkey. Data were collected using a sociodemographic questionnaire, the Self-Directed Learning Readiness Scale, and Time Management Questionnaire. RESULTS: Mean scores were as follows: self-directed learning readiness, 159.12 (SD = 20.8); time management, 87.75 (SD = 12.1). A moderate positive correlation was found between self-directed learning readiness and time management values. Time management scores were 78.42 when self-directed learning readiness was <=149 and 90.82 when self-directed learning readiness was >= 150, with a statistically significant difference (p = .000). CONCLUSION: Level of self-directed learning and academic achievement were higher in students who managed their time well. PMID- 29461442 TI - 3D Endoscopic Donor Nephrectomy Versus Robot-assisted Donor Nephrectomy: A Detailed Comparison of 2 Prospective Cohorts. AB - BACKGROUND: There are 2 endoscopic surgical techniques that implement 3 dimensional (3D) vision to overcome visual misperception: 3D endoscopy and the da Vinci surgical system. 3D endoscopy has several advantages, such as the presence of tactile feedback and easy implementation, at lower costs. We aimed to assess whether 3D endoscopy could be an alternative to the robot during living donor nephrectomy. METHODS: Between April 2015 and April 2016, we prospectively collected data on 40 patients undergoing 3D endoscopic living donor nephrectomies in 1 center, performed by a da Vinci-certified surgeon. Data on donors' perioperative results and recipient and graft survival were collected. These data were compared to 40 robot-assisted donor nephrectomies performed in the same center (between January 2012 and May 2014). RESULTS: Baseline characteristics for both groups were comparable. Intraoperative results showed a significantly shorter median skin-to-skin time of 138.5 minutes (125.8-163.8) versus 169.0 (141.5-209.8) minutes in favor of the 3D group (P = 0.001). Warm ischemia time (P = 0.003) and hilar phase for both single (1 artery and vein) and multiple anatomies (>=1 artery and/or vein [P = 0.002 and P = 0.010, respectively]) were also significantly reduced in favor of the 3D group, with a flat learning curve. Follow-up demonstrated no readmissions nor significant differences for donors, recipients, and graft survival. CONCLUSIONS: 3D endoscopy may be a good alternative to robot-assisted donor nephrectomy because morbidity, graft, and recipient survival were comparable, with a significantly shorter median skin-to skin time, warm ischemia time, and hilar dissection phase. Furthermore, implementation was easy and at lower costs, whereas tactile feedback was preserved. PMID- 29461444 TI - The Effect of Ecmo on the New Vancomycin Dosing Regimen in Critically Ill Patients Receiving Continuous Veno-Venous Hemofiltration. AB - BACKGROUND: The optimal dosing regimen of vancomycin for critically ill patients receiving continuous veno-venous hemofiltration (CVVH) remains controversial, not to mention those with concurrent use of extracorporeal membrane oxygenation (ECMO). We aimed to determine if a new dosing regimen can achieve the target vancomycin trough concentration (Ctrough) of 10-20 MUg/mL in patients receiving CVVH with or without ECMO. METHODS: We conducted a retrospective study by enrolling patients who received vancomycin while undergoing CVVH. The vancomycin dosing regimen was 15-20 mg/kg as the loading dose and 7.5 mg/kg every 12 h as the maintenance doses. Serum concentration was determined after at least four doses of vancomycin were given. RESULTS: A total of 38 patients were enrolled, of which 21 were also on ECMO. The ultrafiltration rate of CVVH was 30.6 +/- 5.5 mL/kg/h with the Ctrough of 14.7 +/- 3.5 MUg/mL. Ctrough was within the target range in 82% of patients. All CVVH-only patients achieved the target concentration, while only 76.2% of those with concurrent ECMO did (p = 0.031). CONCLUSIONS: All patients receiving CVVH achieved the target Ctrough with this new dosing regimen, but those with concurrent ECMO did not. Ctrough must be more closely monitored in patients using ECMO simultaneously. PMID- 29461443 TI - Evaluation of Multiple Linear Regression-Based Limited Sampling Strategies for Enteric-Coated Mycophenolate Sodium in Adult Kidney Transplant Recipients. AB - BACKGROUND: Although multiple linear regression-based limited sampling strategies (LSSs) have been published for enteric-coated mycophenolate sodium, none have been evaluated for the prediction of subsequent mycophenolic acid (MPA) exposure. This study aimed to examine the predictive performance of the published LSS for the estimation of future MPA area under the concentration-time curve from 0 to 12 hours (AUC0-12) in renal transplant recipients. METHODS: Total MPA plasma concentrations were measured in 20 adult renal transplant patients on 2 occasions a week apart. All subjects received concomitant tacrolimus and were approximately 1 month after transplant. Samples were taken at 0, 0.33, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 6, and 8 hours and 0, 0.25, 0.5, 0.75, 1, 1.25, 1.5, 2, 3, 4, 6, 9, and 12 hours after dose on the first and second sampling occasion, respectively. Predicted MPA AUC0-12 was calculated using 19 published LSSs and data from the first or second sampling occasion for each patient and compared with the second occasion full MPA AUC0-12 calculated using the linear trapezoidal rule. Bias (median percentage prediction error) and imprecision (median absolute prediction error) were determined. RESULTS: Median percentage prediction error and median absolute prediction error for the prediction of full MPA AUC0-12 were <15% for 4 LSSs, using the data from the same (second) occasion. One equation (1.583C1 + 0.765C2 + 0.369C2.5 + 0.748C3 + 1.518C4 + 2.158C6 + 3.292C8 + 3.6690) showed bias and imprecision <15% for the prediction of future MPA AUC0-12, where the predicted AUC0-12 from the first occasion was compared with the full AUC0-12 from the second. All LSSs with an acceptable predictive performance included concentrations taken at least 6 hours after the dose. CONCLUSIONS: Only one LSS had an acceptable bias and precision for future estimation. Accurate dosage prediction using a multiple linear regression-based LSS was not possible without concentrations up to at least 8 hours after the dose. PMID- 29461445 TI - Impact of Anesthesia on Hospital Mortality and Morbidities in Geriatric Patients Following Emergency Hip Fracture Surgery. AB - OBJECTIVES: To determine the impact of anesthesia type on in-hospital mortality and morbidity for geriatric fragility hip fracture surgery. DESIGN: Retrospective cohort study. SETTING: Integrates health care delivery system across 38 facilities in the United States. PATIENTS/PARTICIPANTS: We identified 16,695 patients 65 years of age and older who underwent emergent hip fracture repairs between 2009 and 2014 through the Kaiser Permanente hip fracture registry and excluded pathologic or bilateral fractures. INTERVENTION: Hip fracture surgery with general or regional anesthesia. MAIN OUTCOMES MEASURES: Data on in-hospital mortality, time to death, discharge disposition, and length of stay (LOS) were analyzed among the following anesthesia types: general anesthesia (GA), regional anesthesia (RA), and intraoperative conversions from regional to general (Cv). RESULTS: Compared with RA, the hazard ratio for GA for in-hospital mortality was 1.38 and 2.23 for the Cv group; the time ratio for GA-associated time to death was 0.97 and 0.89 for the Cv group. The GA-associated time ratio for LOS before discharge was 1.01, and the hazard ratio for home discharge was 0.86, but no significance was found with the Cv group. CONCLUSIONS: RA may offer advantages over GA for fragility hip fracture surgeries when possible. In-hospital mortality, time to death, increased LOS, and discharge to an institute rather than home were all adversely influenced by GA. Furthermore, the previously understudied Cv group demonstrated adverse outcomes for in-hospital mortality and time to death. LEVEL OF EVIDENCE: Therapeutic Level III.

AB - OBJECTIVES: The surgical reduction of intra-articular olecranon fractures is judged primarily on the lateral elbow radiograph, as orthogonal imaging of the articular surface is not obtainable. We sought to determine surgeon accuracy in identifying intra-articular olecranon malreductions on the lateral elbow radiograph. METHODS: Six human fresh-frozen cadaveric elbow specimens were sagittally sectioned in 5-mm increments after olecranon dissection, preservation of soft tissue envelope, and rigid fixation of the elbow in an external fixator. Three patterns of central intra-articular olecranon malreduction were created in each elbow using a ruler and bone saw. Perfect lateral elbow radiographs were taken of each malreduction, and these images were randomized along with x-rays of normal cadaveric olecranons. The image series was presented to 4 masked trauma trained surgeons to determine whether the olecranon was malreduced or anatomic. Surgeons interpreted the same image series on 2 separate occasions separated by 6 weeks. Percent correct was recorded, and the interobserver and intraobserver reliability was calculated. RESULTS: Orthopedic trauma surgeons correctly identified olecranon malreductions only 73% of the time on the lateral elbow radiograph. Interobserver agreement was moderate for the first review of images and fair for the second review, with respective Fleiss Kappa values of 0.43 and 0.28. Intrarater reliability revealed moderate agreement with Cohen's Kappa value ranging from 0.56 to 0.66. CONCLUSIONS: Intra-articular olecranon malreductions are inconsistently recognized by trauma surgeons on the lateral elbow radiograph. Therefore, articular incongruity may still be present after surgical fixation of comminuted olecranon fractures. We must further define the radiographic anatomic representation of the articular olecranon to improve surgical reduction and clinical outcomes.

AB - BACKGROUND: We previously demonstrated that 80% of Kawasaki disease (KD) patients who develop coronary artery lesions (CALs) have them at diagnosis. We postulated that KD patients presenting with CALs represent a group that may benefit from more aggressive initial therapy. Infliximab has been shown to decrease inflammation in KD patients when added to standard therapy. We compared outcomes of KD patients with CALs initially treated with intravenous immunoglobulin (IVIG) alone versus IVIG plus infliximab. METHODS: Medical records of KD patients from January 2009 to July 2016 were retrospectively reviewed. CALs were defined as a left anterior descending or right coronary artery Z score >=2.5. KD patients with CALs on initial echocardiogram treated with IVIG alone were compared with those treated with IVIG plus infliximab. Clinical characteristics were compared between groups using Wilcoxon rank-sum test, chi test and Fischer's exact tests; length of stay was analyzed using log-normal regression and need for additional therapy using logistic regression. Effect of treatment on CALs between groups was assessed using linear mixed models. RESULTS: Sixty-nine KD patients with CALs at presentation were included. Fifteen of 34 (44%) patients treated with IVIG alone required additional therapy compared with 4 of 35 (11%) patients treated with IVIG plus infliximab (P = 0.003). There were no significant differences between treatment groups for length of stay, CALs or C-reactive protein fall. CONCLUSIONS: IVIG plus infliximab as initial therapy reduces the need for additional therapy in KD patients presenting with CALs. Intensified initial therapy, consisting of infliximab plus IVIG, could be considered for this group of KD patients. PMID- 29461448 TI - Aerococcus urinae as the Causative Agent in Infective Endocarditis of the Aortic Valve in a Pediatric Patient. AB - Aerococcus species were first described in 1953. They have been previously described as the causative agent of urinary tract infections in the elderly but rarely the causative agent for severe infections. However, there are very few cases reported in the pediatric population. To our knowledge, we report the first case of an adolescent with infective endocarditis caused by Aerococcus urinae. PMID- 29461449 TI - Optimizing Vancomycin Monitoring in Pediatric Patients. AB - BACKGROUND: Several studies have reported that trough levels may not be optimal for monitoring vancomycin therapy, because of overexposure and nephrotoxicity risks. Therefore, we developed a population pharmacokinetic model to optimize vancomycin dosing and monitoring in pediatrics. METHODS: Data were retrospectively collected on 76 pediatric patients 1-12 years of age, admitted to general pediatric wards or intensive care units at King Saud University Medical City, Riyadh, Saudi Arabia. The predictability of 3 methods for calculating the area under the curve (AUC) at steady state was assessed for optimum vancomycin therapy monitoring. The 3 methods were simple linear regression, Bayesian approach and the 2-sample pharmacokinetic equation method. We also used Monet Carlo simulations to evaluate the dosing of vancomycin. RESULTS: A 1-compartment model adequately described the data. A strong correlation occurred between the observed and predicted AUC from 0 to 24 hours (AUC0-24h) calculated using the Bayesian approach with a trough sample only or pharmacokinetic equations based on 2 measured samples (R = 0.93 and 0.92, respectively). For the simple linear regression method with a trough sample only, the predicted AUC0-24h at steady state with vancomycin trough levels of 10, 15 and 20 ug/mL were 413, 548 and 714 ug.hour/mL, respectively. The target AUC0-24h above 400 was achieved in 46% and 95% of individuals with trough values of 7-11 and 11-15 ug/mL, respectively. Monte Carlo simulations showed that 60-80 mg/kg/d doses are needed to optimize vancomycin therapy. CONCLUSIONS: In conclusion, targeting vancomycin trough levels above 15 ug/mL in pediatrics would overshoot the target AUC0-24h above 400 and expose them to unnecessary adverse events. PMID- 29461450 TI - Utility of the Performance of Lumbar Puncture for Febrile Children With Status Epilepticus in the Bacterial Conjugate Vaccine Era. AB - BACKGROUND: The necessity of lumbar puncture for the differentiation of central nervous system infection in children with febrile status epilepticus (FSE) remains controversial. The aim of the present study is to investigate the diagnostic necessity of lumbar puncture for children with FSE after the introduction of bacterial conjugate vaccines into the infant immunization program. METHODS: Our retrospective cohort study was performed in children 6 to 60 months of age who were admitted to the pediatric ward at Kitakyushu General Hospital from January 1, 2011, to December 31, 2015, for seizures with fever. Of these patients, we compared the clinical characteristics between the patients initially diagnosed as having FSE and complex febrile seizures excluding FSE (non FSE). RESULTS: Of the eligible 333 children, 98 and 235 children were classified into FSE and non-FSE groups, respectively. The proportion of the children who underwent lumbar puncture in FSE group was significantly higher than that in non FSE group (P < 0.0001). On the other hand, no significant difference in the proportion of the patients with abnormal cerebrospinal fluid findings was seen between the 2 groups. There was no patient with bacterial meningitis. The proportion of patients with encephalitis/encephalopathy in FSE group (n = 7, 7.1%) was significantly higher than that in non-FSE group (n = 0, P = 0.0003). However, only 1 of 6 patients with encephalitis/encephalopathy who underwent lumber puncture showed pleocytosis in cerebrospinal fluid. CONCLUSIONS: Routine lumbar puncture for the differentiation of severe central nervous system infection cannot be recommended in children with FSE. PMID- 29461451 TI - Similarities and Differences Between Physician Assistant Program and Medical School Mission Statement Themes. AB - PURPOSE: The purpose of this study was to examine the concordance of US physician assistant (PA) program mission statements with those of US public- and private sponsored medical schools. With the exception of a broader medical school focus on research, the authors hypothesized that little difference in mission statement congruence would be found in a comparison of medical schools and PA programs. METHODS: Mission statements of 209 of the 210 accredited US PA programs as of May 2016 were obtained and analyzed. Keywords and phrases were identified, coded, and analyzed using NVivo. Themes that previously reported medical school mission statement analyses (including education, research, service, primary care, diversity, prevention, provider distribution, and cost control) were examined. Additional themes of evidence-based medicine (EBM), interprofessional care, patient safety, and quality improvement were included in the analyses. RESULTS: Analyses revealed similar emphasis in both PA programs and medical schools on themes of education, prevention, and cost control, with dissimilar emphases on themes of research, service, primary care, diversity, and provider distribution. Physician assistant programs were more likely to emphasize interprofessional care than EBM, patient safety, or quality improvement. CONCLUSIONS: In the comparison of mission statements of medical schools and PA programs, much less congruence was found than had been hypothesized. Although this study examined the similarities and differences between the mission statements of US medical schools and PA programs, it did not examine the extent to which programs succeeded in meeting the stated missions. Additional research is necessary to understand the factors that determine whether mission statements are actualized in measurable deliverables. PMID- 29461452 TI - Continuing Dermatology Education for Rural Physician Assistants in Ghana: An Assessment of Needs and Effectiveness. AB - PURPOSE: To assess the effectiveness of lectures for continuing medical education (CME) in dermatology in a global health setting and to determine provider and patient demographics of physician assistants (PAs) practicing in rural Ghana. METHODS: Physician assistants from Ghana who attended dermatology lectures at the International Seminar for Physician Assistants in 2011 or 2014 were included in this study. Surveys were administered to participants to determine dermatology resource availability, commonly encountered skin diseases, and management practices. Quizzes were administered before and after CME dermatology lectures to assess short-term retention of lecture material. RESULTS: In all, 353 PAs participated in this study. Physician assistants reported seeing an average of 55 patients per day. The most commonly seen skin diseases were infections, with antifungals and antibiotics being the most commonly prescribed medications. Dermatology-related complaints represented 9.5% of total clinic visits. Among practicing PAs, 23.2% reported having internet access. A total of 332 PAs completed the quizzes, and a statistically significant increase in test scores was noted in postlecture quizzes. CONCLUSIONS: This study reinforces the importance of dermatology education for PAs practicing in rural areas of Ghana and lends insight to critical topics for dermatology curriculum development. In addition, the increase in test scores after CME sessions suggests that lectures are an effective tool for short-term retention of dermatology-related topics. Our study indicates that as the need for health workers increases globally and a paradigm shift away from the traditional physician model of care occurs, dermatology training of PAs is not only important but also achievable. PMID- 29461453 TI - Noncognitive Attributes in Physician Assistant Education. AB - Physician assistant (PA) admissions processes have typically given more weight to cognitive attributes than to noncognitive ones, both because a high level of cognitive ability is needed for a career in medicine and because cognitive factors are easier to measure. However, there is a growing consensus across the health professions that noncognitive attributes such as emotional intelligence, empathy, and professionalism are important for success in clinical practice and optimal care of patients. There is also some evidence that a move toward more holistic admissions practices, including evaluation of noncognitive attributes, can have a positive effect on diversity. The need for these noncognitive attributes in clinicians is being reinforced by changes in the US health care system, including shifting patient demographics and a growing emphasis on team based care and patient satisfaction, and the need for clinicians to help patients interpret complex medical information. The 2016 Physician Assistant Education Association Stakeholder Summit revealed certain behavioral and affective qualities that employers of PAs value and sometimes find lacking in new graduates. Although there are still gaps in the evidence base, some tools and technologies currently exist to more accurately measure noncognitive variables. We propose some possible strategies and tools that PA programs can use to formalize the way they select for noncognitive attributes. Since PA programs have, on average, only 27 months to educate students, programs may need to focus more resources on selecting for these attributes than teaching them. PMID- 29461454 TI - A Program's Analysis of Communication Methods With Clinical Preceptors. AB - PURPOSE: Preceptors value communication with physician assistant (PA) educational programs. This study describes preceptors' perspectives about one PA program's established and new communication strategies to promote preceptor development and retention. METHODS: An electronic survey of preceptors was conducted in December 2014. Quantitative and qualitative data were analyzed using descriptive statistics. RESULTS: Eighty-eight of 209 preceptors completed the survey (42% response rate). Preceptors reported satisfaction with communication frequency and quality. The most preferred topics were preceptor benefits, teaching strategies, feedback about students' performance, and program policy updates. Many preceptors reported not receiving communications sent by mail. A majority of preceptors preferred site visits at least once per year and in person. CONCLUSIONS: Understanding preceptors' preferred topics helped the study program increase its emphasis on those topics. Knowledge that many preceptors do not receive mailed communications has prompted the program to use electronic communication for all communication types. The results reinforced the program's approach to site visits. PMID- 29461455 TI - Students at Risk: Addressing Mental Health Issues and Their Legal Implications in Health Professions Students.

AB - PURPOSE: After a cerebrovascular accident (CVA) aerobic deconditioning contributes to diminished physical function. Functional electrical stimulation (FES)-assisted cycling is a promising exercise paradigm designed to target both aerobic capacity and locomotor function. This pilot study aimed to evaluate the effects of an FES-assisted cycling intervention on aerobic capacity and locomotor function in individuals post-CVA. METHODS: Eleven individuals with chronic (>6 months) post-CVA hemiparesis completed an 8-wk (three times per week; 24 sessions) progressive FES-assisted cycling intervention. VO2peak, self-selected, and fastest comfortable walking speeds, gait, and pedaling symmetry, 6-min walk test (6MWT), balance, dynamic gait movements, and health status were measured at baseline and posttraining. RESULTS: Functional electrical stimulation-assisted cycling significantly improved VO2peak (12%, P = 0.006), self-selected walking speed (SSWS, 0.05 +/- 0.1 m.s, P = 0.04), Activities-specific Balance Confidence scale score (12.75 +/- 17.4, P = 0.04), Berg Balance Scale score (3.91 +/- 4.2, P = 0.016), Dynamic Gait Index score (1.64 +/- 1.4, P = 0.016), and Stroke Impact Scale participation/role domain score (12.74 +/- 16.7, P = 0.027). Additionally, pedal symmetry, represented by the paretic limb contribution to pedaling (paretic pedaling ratio [PPR]) significantly improved (10.09% +/- 9.0%, P = 0.016). Although step length symmetry (paretic step ratio [PSR]) did improve, these changes were not statistically significant (-0.05% +/- 0.1%, P = 0.09). Exploratory correlations showed moderate association between change in SSWS and 6 min walk test (r = 0.74), and moderate/strong negative association between change in PPR and PSR. CONCLUSIONS: These results support FES-assisted cycling as a means to improve both aerobic capacity and locomotor function. Improvements in SSWS, balance, dynamic walking movements, and participation in familial and societal roles are important targets for rehabilitation of individuals after CVA. Interestingly, the correlation between PSR and PPR suggests that improvements in pedaling symmetry may translate to a more symmetric gait pattern. PMID- 29461463 TI - Prognostic Value of The Lactate/Albumin Ratio for Predicting 28-Day Mortality in Critically ILL Sepsis Patients. AB - AIM: The aim of this study was to evaluate the clinical utility of the lactate/albumin (L/A) ratio as a predictive factor of 28-day mortality in critically ill sepsis patients. METHODS: This is a retrospective observational study from a prospectively collected multicenter registry of 10 emergency departments (EDs) in teaching hospitals that participated in the Korean Shock Society. It enrolled patients who were 19 years of age or older who had a suspected or confirmed infection and evidence of refractory hypotension or hypoperfusion. The prognostic performance of the L/A ratio and lactate level for predicting 28-day mortality was assessed. Lactate and albumin levels were measured immediately after ED arrival. RESULTS: A total of 946 patients were included, with 22.5% overall 28-day mortality. The area under the receiver operating characteristic curve (AUROC) value of the L/A ratio (0.69, 95% confidence interval [CI] 0.64-0.73, P < 0.01) was higher than that of lactate (0.65, 95% CI 0.61-0.70, P < 0.01) for predicting 28-day mortality. The optimal cutoff of the L/A ratio was 1.32. The AUROC value of the L/A ratio was better than that of lactate regardless of lactate level (normal [<2.0 mmol/L]: 0.68 vs. 0.55; intermediate [>=2.0, < 4.0 mmol/L]: 0.65 vs. 0.50; high [>=4.0 mmol/L]: 0.66 vs. 0.62). In the subgroup with decreased lactate elimination, the AUROC value of the L/A ratio was also significantly higher than that of lactate (hepatic dysfunction: 0.70 vs. 0.66; renal dysfunction: 0.71 vs. 0.67). The L/A ratio cut-off and hypoalbminemia showed further discriminative value for 28-day mortality even in patients with normal or intermediate lactate levels. CONCLUSIONS: The prognostic performance of the L/A ratio was superior to that of a single lactate measurement for predicting 28-day mortality of critically ill sepsis patients. L/A ratio can be a useful prognostic factor regardless of initial lactate level and the presence of hepatic or renal dysfunction. PMID- 29461464 TI - Protective Effects of the Complement Inhibitor Compstatin CP40 in Hemorrhagic Shock. AB - Trauma-induced hemorrhagic shock (HS) plays a decisive role in the development of immune, coagulation, and organ dysfunction often resulting in a poor clinical outcome. Imbalanced complement activation is intricately associated with the molecular danger response and organ damage after HS. Thus, inhibition of the central complement component C3 as turnstile of both inflammation and coagulation is hypothesized as a rational strategy to improve the clinical course after HS.Applying intensive care conditions, anaesthetized, monitored, and protectively ventilated non-human primates (NHP; cynomolgus monkeys) received a pressure controlled severe HS (60 min at MAP 30 mmHg) with subsequent volume resuscitation. Thirty min after HS, animals were randomly treated with either an analog of the C3 inhibitor compstatin (i.e., Cp40) in saline (n = 4) or with saline alone (n = 4). The observation period lasted 300 min after induction of HS.We observed improved kidney function in compstatin Cp40-treated animals after HS as determined by improved urine output, reduced damage markers and a tendency of less histopathological signs of acute kidney injury. Sham-treated animals revealed classical signs of mucosal edema, especially in the ileum and colon reflected by worsened microscopic intestinal injury scores. In contrast, Cp40 treated HS animals exhibited only minor signs of organ edema and significantly less intestinal damage. Furthermore, early systemic inflammation and coagulation dysfunction were both ameliorated by Cp40.The data suggest that therapeutic inhibition of C3 is capable to significantly improve immune, coagulation and organ function and to preserve organ-barrier integrity early after traumatic HS. C3-targeted complement inhibition may therefore reflect a promising therapeutic strategy in fighting fatal consequences of HS. PMID- 29461465 TI - Septic Shock Alters Mitochondrial Respiration of Lymphoid Cell-Lines and Human Peripheral Blood Mononuclear Cells: The Role of Plasma. AB - INTRODUCTION: In septic shock patients, post-septic immunosuppression state following the systemic inflammatory response syndrome is responsible for nosocomial infections, with subsequent increased mortality. The aim of the present study was to assess the underlying cellular mechanisms of the post-septic immunosuppression state, by investigating mitochondrial functions of peripheral blood mononuclear cells (PBMCs) from septic shock patients over 7 days. MATERIALS AND METHODS: Eighteen patients admitted to a French intensive care unit for septic shock were included. At days 1 and 7, PBMCs were isolated by Ficoll density gradient centrifugation. Mitochondrial respiration of intact septic PBMCs was assessed versus control group PBMCs, by measuring O2 consumption in plasma, using high-resolution respirometry. Mitochondrial respiration was then compared between septic plasmas and control plasmas for control PBMCs, septic PBMCs and lymphoid cell-line (CEM). To investigate the role of plasma, we measured several plasma cytokines, among them HMGB1, by ELISA. RESULTS: Basal O2 consumption of septic shock PBMCs was of 8.27 +/- 3.39 and 10.48 +/- 3.99 pmol/s/10 cells at days 1 and 7 respectively, significantly higher than in control PBMCs (5.37 +/- 1.46 pmol/s/10 cells, p < 0.05). Septic patient PBMCs showed a lower response to oligomycin, suggesting a reduced ATP-synthase activity, as well as an increased response to FCCP suggesting an increased mitochondrial respiratory capacity. At 6 hours, septic plasmas showed a decreased O2 consumption of CEM (4.73 +/- 1.46 vs. 6.58 +/- 1.53, p < 0.05) as well as in control group PBMCs (1.76 +/- 0.36 vs. 2.70 +/- 0.42, p < 0.05), and triggered a decreased ATP-synthase activity but an increased response to FCCP. These differences are not explained by different cell survival. High HMGB1 levels were significantly associated with reduced PBMCs mitochondrial respiration. CONCLUSION: Septic plasma impairs mitochondrial respiration in immune cells, with a possible role of the proinflammatory protein HMGB1, leading to a subsequent compensation, probably by enzymatic activation. This compensation result is an improvement of global mitochondrial respiratory capacity, but without restoring ATP-synthase activity. PMID- 29461466 TI - Characterization of the Key Aroma Compounds in Proso Millet Wine Using Headspace Solid-Phase Microextraction and Gas Chromatography-Mass Spectrometry. AB - The volatile compounds in proso millet wine were extracted by headspace solid phase microextraction (85 MUm polyacrylate (PA), 100 MUm polydimethylsiloxane (PDMS), 75 MUm Carboxen (CAR)/PDMS, and 50/30 MUm divinylbenzene (DVB)/CAR/PDMS fibers), and analyzed using gas chromatography-mass spectrometry; the odor characteristics and intensities were analyzed by the odor activity value (OAV). Different sample preparation factors were used to optimize this method: sample amount, extraction time, extraction temperature, and content of NaCl. A total of 64 volatile compounds were identified from the wine sample, including 14 esters, seven alcohols, five aldehydes, five ketones, 12 benzene derivatives, 12 hydrocarbons, two terpenes, three phenols, two acids, and two heterocycles. Ethyl benzeneacetate, phenylethyl alcohol, and benzaldehyde were the main volatile compounds found in the samples. According to their OAVs, 14 volatile compounds were determined to be odor-active compounds (OAV > 1), and benzaldehyde, benzeneacetaldehyde, 1-methyl-naphthalene, 2-methyl-naphthalene, and biphenyl were the prominent odor-active compounds (OAV > 50), having a high OAV. Principal component analysis (PCA) showed the difference of distribution of the 64 volatile compounds and 14 odor-active compounds with four solid-phase microextraction (SPME) fibers. PMID- 29461467 TI - Genome-Wide Analysis of the GRF Family Reveals Their Involvement in Abiotic Stress Response in Cassava. AB - GENERAL REGULATORY FACTOR (GRF) proteins play vital roles in the regulation of plant growth, development, and response to abiotic stress. However, little information is known for this gene family in cassava (Manihot esculenta). In this study, 15 MeGRFs were identified from the cassava genome and were clustered into the epsilon and the non-epsilon groups according to phylogenetic, conserved motif, and gene structure analyses. Transcriptomic analyses showed eleven MeGRFs with constitutively high expression in stems, leaves, and storage roots of two cassava genotypes. Expression analyses revealed that the majority of GRFs showed transcriptional changes under cold, osmotic, salt, abscisic acid (ABA), and H2O2 treatments. Six MeGRFs were found to be commonly upregulated by abiotic stress, ABA, and H2O2 treatments, which may be the converging points of multiple signaling pathways. Interaction network analysis identified 18 possible interactors of MeGRFs. Taken together, this study elucidates the transcriptional control of MeGRFs in tissue development and the responses of abiotic stress and related signaling in cassava. Some constitutively expressed, tissue-specific, and abiotic stress-responsive candidate MeGRF genes were identified for the further genetic improvement of crops. PMID- 29461469 TI - The Prediction of the Gas Utilization Ratio based on TS Fuzzy Neural Network and Particle Swarm Optimization. AB - Gas utilization ratio (GUR) is an important indicator that is used to evaluate the energy consumption of blast furnaces (BFs). Currently, the existing methods cannot predict the GUR accurately. In this paper, we present a novel data-driven model for predicting the GUR. The proposed approach utilized both the TS fuzzy neural network (TS-FNN) and the particle swarm algorithm (PSO) to predict the GUR. The particle swarm algorithm (PSO) is applied to optimize the parameters of the TS-FNN in order to decrease the error caused by the inaccurate initial parameter. This paper also applied the box graph (Box-plot) method to eliminate the abnormal value of the raw data during the data preprocessing. This method can deal with the data which does not obey the normal distribution which is caused by the complex industrial environments. The prediction results demonstrate that the optimization model based on PSO and the TS-FNN approach achieves higher prediction accuracy compared with the TS-FNN model and SVM model and the proposed approach can accurately predict the GUR of the blast furnace, providing an effective way for the on-line blast furnace distribution control. PMID- 29461468 TI - Bullying as a Stressor in Mid-Adolescent Girls and Boys-Associations with Perceived Stress, Recurrent Pain, and Salivary Cortisol. AB - Bullying involves repeated exposure to negative actions while also invoking a power asymmetry between the involved parties. From a stress perspective, being bullied can be seen as a severe and chronic stressor, and an everyday social evaluative threat, coupled with a shortage of effective social resources for dealing with this particular stressor. The aim of this study was to investigate whether exposure to bullying among mid-adolescent girls and boys is associated with subjective and objective stress-related outcomes in terms of perceived stress, recurrent pain, and salivary cortisol. The data came from the School Stress and Support Study (TriSSS) including students in grades 8-9 in two schools in Stockholm, Sweden, in 2010 (study sample n = 392; cortisol subsample n = 198). Bullying was self-reported and measured by multiple items. The statistical analyses included binary logistic and linear (OLS) regression. Being bullied was associated with greater perceived stress and an increased risk of recurrent pain, among both boys and girls. Also, bullied students had lower cortisol output (AUCG) and lower cortisol awakening response (CARG) as compared to those who were not bullied. Gender-stratified analyses demonstrated that these associations were statistically significant for boys but not for girls. In conclusion, this study demonstrated that being bullied was related to both subjective and objective stress markers among mid-adolescent girls and boys, pointing to the necessity of continuously working against bullying. PMID- 29461470 TI - Three-Level De-Multiplexed Dual-Branch Complex Delta-Sigma Transmitter. AB - In this paper, a dual-branch topology driven by a Delta-Sigma Modulator (DSM) with a complex quantizer, also known as the Complex Delta Sigma Modulator (CxDSM), with a 3-level quantized output signal is proposed. By de-multiplexing the 3-level Delta-Sigma-quantized signal into two bi-level streams, an efficiency enhancement over the operational frequency range is achieved. The de-multiplexed signals drive a dual-branch amplification block composed of two switch-mode back to-back power amplifiers working at peak power. A signal processing technique known as quantization noise reduction with In-band Filtering (QNRIF) is applied to each of the de-multiplexed streams to boost the overall performances; particularly the Adjacent Channel Leakage Ratio (ACLR). After amplification, the two branches are combined using a non-isolated combiner, preserving the efficiency of the transmitter. A comprehensive study on the operation of this topology and signal characteristics used to drive the dual-branch Switch-Mode Power Amplifiers (SMPAs) was established. Moreover, this work proposes a highly efficient design of the amplification block based on a back-to-back power topology performing a dynamic load modulation exploiting the non-overlapping properties of the de-multiplexed Complex DSM signal. For experimental validation, the proposed de-multiplexed 3-level Delta-Sigma topology was implemented on the BEEcubeTM platform followed by the back-to-back Class-E switch-mode power amplification block. The full transceiver is assessed using a 4th-Generation mobile communications standard LTE (Long Term Evolution) standard 1.4 MHz signal with a peak to average power ratio (PAPR) of 8 dB. The dual-branch topology exhibited a good linearity and a coding efficiency of the transmitter chain higher than 72% across the band of frequency from 1.8 GHz to 2.7 GHz. PMID- 29461471 TI - Heavy Metals in Notifications of Rapid Alert System for Food and Feed. AB - Heavy metals represent the fourth most often notified hazard category in the Rapid Alert System for Food and Feed (RASFF) from 1980-2016. The goal of the study was to examine the similarities in notifications of particular heavy metals within the RASFF year, product category, notifying country, country of origin, notification basis, notification type, distribution status, risk decision, and action taken, taking into account the particular product type, such as food, food contact material, and feed. The data originated from the RASFF database. Cluster analysis on pivot tables was applied using joining and two-way joining methods. Most notifications concerned food, in which the highest number were related to mercury, cadmium, chromium, lead, arsenic, and nickel. Notifications were mainly related to fish and food contact materials, in addition to fruits and vegetables, seafood, and dietetic food. The number of notifications decreased in 2015 and 2016. The majority of products were notified by Italy, Spain, Germany, and France. The notified products originated mainly from China and Spain. The notification was usually based on official controls on the market, as well as border controls. The notification types were mainly information, alert, and border rejections. Products were not frequently distributed due to distribution restriction to the notifying country or the possibility of distribution to the market. A risk decision was not usually made. The taken actions included re dispatch of products, withdrawal from the market, or destruction. The data on heavy metals from the RASFF database can help European and national authorities in shaping public health. PMID- 29461472 TI - In the Eye of the Beholder: Owner Preferences for Variations in Cats' Appearances with Specific Focus on Skull Morphology. AB - Changes in the popularity of cat breeds are largely driven by human perceptions of, and selection for, phenotypic traits including skull morphology. The popularity of breeds with altered skull shapes appears to be increasing, and owner preferences are an important part of this dynamic. This study sought to establish how and why a range of phenotypic attributes, including skull shape, affect preferences shown by cat owners. Two questionnaires were distributed on line to cat owners who were asked to rate preferences for pictures of cats on a 0 10 scale. Veterinarian consensus established the skull types of the cats pictured (i.e., level of brachycephaly (BC) or dolichocephaly (DC)). Preferences were then explored relative to cat skull type, coat and eye color, and coat length. Generalized estimating equations identified relationships between physical characteristics and respondent ratings. Further sub-analyses explored effects of respondents' occupation, location and previous cat ownership on rating scores. Overall, cats with extreme changes in skull morphology (both BC and DC) were significantly less preferred than mesocephalic cats. Green eyes, ginger coat color and medium length coat were most preferred. Current owners of a BC or DC pure bred cat showed significantly greater preference for cats with similar features and significantly lower preference for the opposite extreme. Respondents from Asia were significantly more likely to prefer both BC and DC cats as compared to respondents from other locations. Finally, those in an animal care profession, as compared to other professions, provided a significantly lower preference rating for BC cats but not for DC cats. This work, despite the acknowledged limitations, provides preliminary evidence that preferences for cat breeds, and their associated skull morphologies, are driven by both cultural and experiential parameters. This information may allow for better targeting of educational materials concerning cat breeds. PMID- 29461473 TI - Temporal and Fine-Grained Pedestrian Action Recognition on Driving Recorder Database. AB - The paper presents an emerging issue of fine-grained pedestrian action recognition that induces an advanced pre-crush safety to estimate a pedestrian intention in advance. The fine-grained pedestrian actions include visually slight differences (e.g., walking straight and crossing), which are difficult to distinguish from each other. It is believed that the fine-grained action recognition induces a pedestrian intention estimation for a helpful advanced driver-assistance systems (ADAS). The following difficulties have been studied to achieve a fine-grained and accurate pedestrian action recognition: (i) In order to analyze the fine-grained motion of a pedestrian appearance in the vehicle mounted drive recorder, a method to describe subtle change of motion characteristics occurring in a short time is necessary; (ii) even when the background moves greatly due to the driving of the vehicle, it is necessary to detect changes in subtle motion of the pedestrian; (iii) the collection of large scale fine-grained actions is very difficult, and therefore a relatively small database should be focused. We find out how to learn an effective recognition model with only a small-scale database. Here, we have thoroughly evaluated several types of configurations to explore an effective approach in fine-grained pedestrian action recognition without a large-scale database. Moreover, two different datasets have been collected in order to raise the issue. Finally, our proposal attained 91.01% on National Traffic Science and Environment Laboratory database (NTSEL) and 53.23% on the near-miss driving recorder database (NDRDB). The paper has improved +8.28% and +6.53% from baseline two-stream fusion convnets.

AB - Parental co-participation in physical activity (PA) may be a beneficial parenting practice for diminishing children's sedentary time (ST). Less information is available, however, on the explanatory role of co-participation in PA regarding parental educational differences in children's ST. Preschool-aged children (N = 864, mean age 4.8, 52% boys) with their parents participated in a cross-sectional DAGIS (Increased Health and Wellbeing in Pre-schools) study between years 2015 and 2016. Children (N = 821) wore an accelerometer for one week. Parents were informed of their educational background, and the frequency of visits with their child in nature, to parks or playgrounds, their own yard, and indoor sport facilities (N = 808). Testing the associations required multiple regression analyses. Parents with a low educational background reported more frequent visits with their child to their own yard, and these visits were associated with children's lower ST. More highly educated parents co-visited indoor sport facilities more frequently, although this did not have a significant association with children's ST. More frequent visits in nature were associated with a lower ST at weekends, regardless of educational background. Future health promotion strategies should inform parents that frequent co-participation in PA, for example, in one's own yard, is beneficial for lowering children's ST. PMID- 29461475 TI - Octodrine: New Questions and Challenges in Sport Supplements. AB - Background: Octodrine is the trade name for Dimethylhexylamine (DMHA), a central nervous stimulant that increases the uptake of dopamine and noradrenaline. Originally developed as a nasal decongestant in the 1950's, it has recently been re-introduced on the market as a pre-workout and 'fat-burner' product but its use remains unregulated. Our work provides the first observational cross-sectional analytic study on Octodrine as a new drug trend and its associated harms after a gap spanning seven decades. Methods: A comprehensive multilingual assessment of literature, websites, drug fora and other online resources was carried out with no time restriction in English, German, Russian and Arabic. Keywords included Octodrine's synonyms and chemical isomers. Results: Only five relevant publications emerged from the literature search, with most of the available data on body building websites and fora. Since 2015, Octodrine has been advertised online as "the next big thing" and "the god of stimulants," with captivating marketing strategies directed at athletes and a wider cohort of users. Reported side-effects include hypertension, dyspnoea and hyperthermia. Conclusions: The uncontrolled use of Octodrine, its physiological and psychoactive effects raise serious health implications with possible impact on athletes and doping practices. This new phenomenon needs to be thoroughly studied and monitored.

AB - An audit of 'standard' (STD) and 'energy and protein fortified' (HEHP) meals from Meals on Wheels (MOW) South Australia's summer menu was conducted to evaluate the consistency, and serve size and nutrient contents, of their menu items. Twenty soups, 20 mains and 20 desserts from each of the STD and HEHP menus were prepared at the MOW South Australia's kitchen and delivered to three 'sham(dummy)-clients' over a 5-week period. Each meal component was weighed in triplicate, to the nearest gram, the variation within the serve weight was calculated, and the overall energy and protein content of each meal was determined using FoodWorks (Xyris Software, Highgate Hill, Queensland, Australia). On average, the variability for soups and mains was <=6% and for desserts was <=10% and although the measured serve sizes of the MOW meals were consistently smaller than prescribed serve size, the differences were minor. As a percentage of recommended daily intakes (RDIs) for adults aged over 60 years, we calculated that the STD meals contained 21-39% for energy and 42-63% for protein while the HEHP meals contained 29-55% for energy and 46-69% for protein. These findings demonstrate that MOW meals currently meet the voluntary meal guidelines for energy and protein. PMID- 29461478 TI - Computational and Experimental Mechanical Modelling of a Composite Grouted Splice Sleeve Connector System. AB - Owing to its controllable tolerance, simple operation and no need for welding at construction site, the composite system involving grouted cement material, steel material and ductile iron material is widely used as grouted splice sleeve (GSS) connector for connecting precast concrete structures. However, the current design recommendations for such a composite connection system do not accurately account for its material nonlinearity behavior. In the present study, a three-dimensional nonlinear finite element model of a GSS connector is developed by considering the nonlinear material behavior of each component to fully investigate its mechanical performance under axial tension. To validate the proposed computational model and demonstrate the nonlinear response of the GSS connector, the pullout experimental test of two engineering specimens is carried out under monotonic tensile load, and a good agreement between the numerical and experimental test results is observed. Then, the sensitivity analysis of some controlling material properties and geometrical parameters is performed using the validated computational model to further understand the performance of such a composite structure in load carrying capacity and ductility of the connections to meet the rapid engineering applications of precast concrete structures. PMID- 29461477 TI - Anti-Renal Fibrotic Effect of Exercise Training in Hypertension. AB - The purpose of this study was to evaluate the effects of exercise training on renal fibrosis in hypertensive rats. Masson's trichrome staining and Western blotting were performed on the excised renal cortex from sixteen male spontaneously hypertensive rats (SHR), which were randomly divided into either a sedentary hypertensive group (SHR) or exercise hypertensive group (SHR-EX, running on an exercise treadmill for 60 min/day, 5 sessions/week, for 12 weeks), and from eight male Wistar-Kyoto rats which served as a sedentary normotensive group (WKY). The systolic blood pressure (SBP) and renal fibrosis in hypertensive rats improved after exercise training. The inflammatory-related protein levels of interleukin-6 (IL-6) and cyclooxygenase-2 (COX-2), as well as the fibrotic related protein levels of transforming growth factor-beta (TGF-beta), phospho Smad2/3 (p-Smad2/3), connective tissue growth factor (CTGF), matrix metalloproteinase-9 (MMP-9), and matrix metalloproteinase-2 (MMP-2) were decreased in the SHR-EX group when compared with the SHR group. Exercise training suppressed the hypertension-induced renal cortical inflammatory and fibrotic pathways in hypertensive rat models. These findings might indicate a new therapeutic effect for exercise training to prevent renal fibrosis in hypertensive nephropathy. PMID- 29461480 TI - Biocontrol of Fusarium graminearum sensu stricto, Reduction of Deoxynivalenol Accumulation and Phytohormone Induction by Two Selected Antagonists. AB - Fusarium head blight (FHB) is a devastating disease that causes extensive yield and quality losses to wheat and other small cereal grains worldwide. Species within the Fusarium graminearum complex are the main pathogens associated with the disease, F. graminearum sensu stricto being the main pathogen in Argentina. Biocontrol can be used as part of an integrated pest management strategy. Phytohormones play a key role in the plant defense system and their production can be induced by antagonistic microorganisms. The aims of this study were to evaluate the effect of the inoculation of Bacillus velezensis RC 218, F. graminearum and their co-inoculation on the production of salicylic acid (SA) and jasmonic acid (JA) in wheat spikes at different periods of time under greenhouse conditions, and to evaluate the effect of B. velezensis RC 218 and Streptomyces albidoflavus RC 87B on FHB disease incidence, severity and deoxynivalenol accumulation on Triticum turgidum L. var. durum under field conditions. Under greenhouse conditions the production of JA was induced after F. graminearum inoculation at 48 and 72 h, but JA levels were reduced in the co-inoculated treatments. No differences in JA or SA levels were observed between the B. velezensis treatment and the water control. In the spikes inoculated with F. graminearum, SA production was induced early (12 h), as it was shown for initial FHB basal resistance, while JA was induced at a later stage (48 h), revealing different defense strategies at different stages of infection by the hemibiotrophic pathogen F. graminearum. Both B. velezensis RC 218 and S. albidoflavus RC 87B effectively reduced FHB incidence (up to 30%), severity (up to 25%) and deoxynivalenol accumulation (up to 51%) on durum wheat under field conditions. PMID- 29461479 TI - Donor Human Milk Protects against Bronchopulmonary Dysplasia: A Systematic Review and Meta-Analysis. AB - Bronchopulmonary dysplasia (BPD) is the most common complication after preterm birth. Pasteurized donor human milk (DHM) has increasingly become the standard of care for very preterm infants over the use of preterm formula (PF) if the mother's own milk (MOM) is unavailable. Studies have reported beneficial effects of DHM on BPD. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) and observational studies on the effects of DHM on BPD and other respiratory outcomes. Eighteen studies met the inclusion criteria. Meta analysis of RCTs could not demonstrate that supplementation of MOM with DHM reduced BPD when compared to PF (three studies, risk ratio (RR) 0.89, 95% confidence interval (CI) 0.60-1.32). However, meta-analysis of observational studies showed that DHM supplementation reduced BPD (8 studies, RR 0.78, 95% CI 0.67-0.90). An exclusive human milk diet reduced the risk of BPD, compared to a diet with PF and/or bovine milk-based fortifier (three studies, RR 0.80, 95% CI 0.68-0.95). Feeding raw MOM, compared to feeding pasteurized MOM, protected against BPD (two studies, RR 0.77, 95% CI 0.62-0.96). In conclusion, our data suggest that DHM protects against BPD in very preterm infants. PMID- 29461481 TI - A Dislocation-Scale Characterization of the Evolution of Deformation Microstructures around Nanoindentation Imprints in a TiAl Alloy. AB - In this work, plastic deformation was locally introduced at room temperature by nanoindentation on a gamma-TiAl-based alloy. Comprehensive analyses of microstructures were performed before and after deformation. In particular, the Burgers vectors, the line directions, and the mechanical twinning systems were studied via accurate electron channeling contrast imaging. Accommodation of the deformation are reported and a scenario is proposed. All features help to explain the poor ductility of the TiAl-based alloys at room temperature. PMID- 29461482 TI - Fiber Intake and Insulin Resistance in 6374 Adults: The Role of Abdominal Obesity. AB - A cross-sectional design was used to evaluate the relationship between fiber intake and insulin resistance, indexed using HOMA (homeostatic model assessment), in a National Health and Nutrition Examination Study (NHANES) sample of 6374 U.S. adults. Another purpose was to test the influence of covariates on the association. A third aim was to compare HOMA levels between two groups based on the recommended intake of 14 grams of fiber per 1000 kilocalories (kcal). Fiber intake was measured using a 24-hour recall. With demographic variables controlled, results showed that HOMA differed across High, Moderate, and Low fiber categories (F = 5.4, p = 0.0072). Adjusting for the demographic variables, the possible misreporting of energy intake, smoking, and physical activity strengthened the relationship (F = 8.0, p = 0.0009), which remained significant after adjusting for body fat (F = 7.0, p = 0.0019) and body mass index (BMI) (F = 4.9, p = 0.0108), with the other covariates. However, the fiber-HOMA relationship was eliminated after adjusting for waist circumference (F = 2.3, p = 0.1050). Dividing participants based on the recommended 14-gram standard resulted in meaningful HOMA differences (F = 16.4, p = 0.0002), and the association was not eliminated after controlling for waist circumference. Apparently, adults with high fiber consumption have less insulin resistance than their counterparts. However, much of the association is due to differences in waist circumference, unless the recommended intake of fiber is attained. PMID- 29461483 TI - Influence of Iron Deficiency on HbA1c Levels in Pregnant Women: Comparison with Non-Pregnant Women. AB - Although HbA1c is widely used as a glycemic control indicator, HbA1c is known to show falsely high levels in patients in an iron deficient state (IDS). We compared the influence of IDS on HbA1c levels between pregnant women, due to mainly an increase in demand for iron without bleeding, and non-pregnant women, due to mainly bleeding (menstruation). We studied 42 non-diabetic pregnant women (pregnant group) and 42 age-matched non-pregnant women with normal glucose tolerance (non-pregnant group). We compared HbA1c and glycated albumin (GA) levels between IDS and normal iron state (NIS) in both groups. Furthermore, we analyzed the correlation between indicators of glycemic control and iron-related parameters [mean corpuscular hemoglobin, serum transferrin saturation (%Tf), and serum ferritin] in both groups. Compared with non-pregnant women, pregnant women had significantly lower %Tf and serum ferritin levels and significantly higher morbidity of IDS. HbA1c, but not GA, had significantly higher levels in pregnant women with IDS compared with NIS; however, HbA1c in non-pregnant women showed no significant difference for both IDS and NIS. In pregnant women, significant negative correlations were observed between HbA1c and iron-related parameters. In non-pregnant women, negative correlations were observed between HbA1c and these parameters, but they were not significant. No significant correlations were observed between GA and iron-related parameters in both groups. HbA1c levels in pregnant women were found to be largely affected by iron deficiency compared with non-pregnant women. For this reason, GA, which is not affected by iron deficiency, is desirable for use in the assessment of glycemic control during pregnancy.

AB - Anatase (TiO2) and multiwalled carbon nanotubes bearing polyethylenimine (PEI) anchored on their surface were hybridized in different proportions according to a sol-gel method. The resulting nanocomposites (TiO2@PEI-MWCNTs), characterized by BET, XRD, XPS, SEM, and UV techniques, were found efficient catalysts for CO2 photoreduction into formic and acetic acids in water suspension and under visible light irradiation. PEI-grafted nanotubes co-catalysts are believed to act as CO2 activators by forming a carbamate intermediate allowing to accomplish the first example in the literature of polyamines/nanotubes/TiO2 mediated CO2 photoreduction to carboxylic acids.

AB - Surgery of temporal lobe epilepsy is the best opportunity for seizure freedom in medically intractable patients. The surgical approach has evolved to recognize the paramount importance of the mesial temporal structures in the majority of patients with temporal lobe epilepsy who have a seizure origin in the mesial temporal structures. For those individuals with medically intractable mesial temporal lobe epilepsy, a selective amygdalohippocampectomy surgery can be done that provides an excellent opportunity for seizure freedom and limits the resection to temporal lobe structures primarily involved in seizure genesis. PMID- 29461486 TI - From Prenatal to Preimplantation Genetic Diagnosis of beta-Thalassemia. Prevention Model in 8748 Cases: 40 Years of Single Center Experience. AB - The incidence of beta-thalassemia in Sardinia is high and beta-39 is the most common mutation. The prevention campaign started in 1977 and was performed in a single center (Microcitemico Hospital, Cagliari, Sardinia, Italy). It was based on educational programs, population screening by hematological and molecular identification of the carriers. Prenatal and pre-implantation diagnosis was offered to couples at risk. 8564 fetal diagnosis procedures using different invasive approaches and analysis techniques were performed in the last 40 years. Trans-abdominal chorionic villous sampling was preferred due to lower complication risks and early diagnosis. Chorionic villous DNA was analyzed by PCR technique. 2138 fetuses affected by beta-thalassemia were diagnosed. Women opted for termination of the pregnancy (TOP) in 98.2% of these cases. Pre-implantation genetic diagnosis (PGD) was proposed to couples at risk to avoid TOP. A total of 184 PGD were performed. Initially, the procedure was exclusively offered to infertile couples, according to the law in force. The success rate of pregnancies increased from 11.1% to 30.8% when, crucial law changes were enacted, and PGD was offered to fertile women as well. Forty years of beta-thalassemia prevention programs in Sardinia have demonstrated the important decrease of this severe genetic disorder. PMID- 29461487 TI - Understanding the Role of Negative Emotions in Adult Learning and Achievement: A Social Functional Perspective. AB - The role of emotions in adult learning and achievement has received increasing attention in recent years. However, much of the emphasis has been on test anxiety, rather than the wider spectrum of negative emotions such as sadness, grief, boredom and anger. This paper reports findings of a qualitative study exploring the experience and functionality of negative emotions at university. Thirty-six academic staff and students from an Australian university were interviewed about emotional responses to a range of learning events. Data analysis was informed by a prototype approach to emotion research. Four categories of discrete negative emotions (anger, sadness, fear, boredom) were considered by teachers and students to be especially salient in learning, with self-conscious emotions (guilt, embarrassment, shame) mentioned by more students than staff. While negative emotions were frequently viewed as detrimental to motivation, performance and learning, they were also construed under some circumstances as beneficial. The findings are discussed in relation to the value of social functional approaches for a better understanding of the diverse roles of negative emotions in learning and achievement. PMID- 29461488 TI - Blood Mononuclear Cell Mitochondrial Respiratory Chain Complex IV Activity Is Decreased in Multiple Sclerosis Patients: Effects of beta-Interferon Treatment. AB - OBJECTIVES: Evidence of mitochondrial respiratory chain (MRC) dysfunction and oxidative stress has been implicated in the pathophysiology of multiple sclerosis (MS). However, at present, there is no reliable low invasive surrogate available to evaluate mitochondrial function in these patients. In view of the particular sensitivity of MRC complex IV to oxidative stress, the aim of this study was to assess blood mononuclear cell (BMNC) MRC complex IV activity in MS patients and compare these results to age matched controls and MS patients on beta-interferon treatment. METHODS: Spectrophotometric enzyme assay was employed to measure MRC complex IV activity in blood mononuclear cell obtained multiple sclerosis patients and aged matched controls. RESULTS: MRC Complex IV activity was found to be significantly decreased (p < 0.05) in MS patients (2.1 +/- 0.8 k/nmol * 10-3; mean +/- SD] when compared to the controls (7.2 +/- 2.3 k/nmol * 10-3). Complex IV activity in MS patients on beta-interferon (4.9 +/- 1.5 k/nmol * 10-3) was not found to be significantly different from that of the controls. CONCLUSIONS: This study has indicated evidence of peripheral MRC complex IV deficiency in MS patients and has highlighted the potential utility of BMNCs as a potential means to evaluate mitochondrial function in this disorder. Furthermore, the reported improvement of complex IV activity may provide novel insights into the mode(s) of action of beta-interferon. PMID- 29461489 TI - A Model-Driven Co-Design Framework for Fusing Control and Scheduling Viewpoints. AB - Model-Driven Engineering (MDE) is widely applied in the industry to develop new software functions and integrate them into the existing run-time environment of a Cyber-Physical System (CPS). The design of a software component involves designers from various viewpoints such as control theory, software engineering, safety, etc. In practice, while a designer from one discipline focuses on the core aspects of his field (for instance, a control engineer concentrates on designing a stable controller), he neglects or considers less importantly the other engineering aspects (for instance, real-time software engineering or energy efficiency). This may cause some of the functional and non-functional requirements not to be met satisfactorily. In this work, we present a co-design framework based on timing tolerance contract to address such design gaps between control and real-time software engineering. The framework consists of three steps: controller design, verified by jitter margin analysis along with co simulation, software design verified by a novel schedulability analysis, and the run-time verification by monitoring the execution of the models on target. This framework builds on CPAL (Cyber-Physical Action Language), an MDE design environment based on model-interpretation, which enforces a timing-realistic behavior in simulation through timing and scheduling annotations. The application of our framework is exemplified in the design of an automotive cruise control system.

AB - The phospholipids phosphatidylserine (PS) and phosphatidylethanolamine (PE) play important roles in the virulence of Candida albicans and loss of PS synthesis or synthesis of PE from PS (PS decarboxylase) severely compromises virulence in C. albicans in a mouse model of systemic candidiasis. This review discusses synthesis of PE and PS in C. albicans and mechanisms by which these lipids impact virulence in this fungus. This is further compared to how PS and PE synthesis impact virulence in other fungi, parasites and bacteria. Furthermore, the impact of PS asymmetry on virulence and extracellular vesicle formation in several microbes is reviewed. Finally, the potential for PS and PE synthases as drug targets in these various kingdoms is also examined. PMID- 29461492 TI - Layup Configuration Effect on Notch Residual Strength in Composite Laminates. AB - The current trend shows an increasing demand for composites due to their high stiffness to weight ratio and the recent progress in manufacturing and cost reduction of composites. To combine high strength and stiffness in a cost effective way, composites are often joined with steel or aluminum. However, joining of thermoset composite materials is challenging because circular holes are often used to join them with their metal counterparts. These design based circular holes induce high stress concentration around the hole. The purpose of this paper is to focus on layup configuration and its impact on notch stress distribution. To ensure high quality and uniformity, the holes were machined by a 5 kW continuous wave (cw) CO2 laser. The stress distribution was evaluated and compared by using finite element analysis and Lekhnitskii's equations. For further understanding, the notch strength of the laminates was compared and strain distributions were analyzed using the digital image correlation technique. PMID- 29461493 TI - Design and Implementation of e-Health System Based on Semantic Sensor Network Using IETF YANG. AB - Recently, healthcare services can be delivered effectively to patients anytime and anywhere using e-Health systems. e-Health systems are developed through Information and Communication Technologies (ICT) that involve sensors, mobiles, and web-based applications for the delivery of healthcare services and information. Remote healthcare is an important purpose of the e-Health system. Usually, the eHealth system includes heterogeneous sensors from diverse manufacturers producing data in different formats. Device interoperability and data normalization is a challenging task that needs research attention. Several solutions are proposed in the literature based on manual interpretation through explicit programming. However, programmatically implementing the interpretation of the data sender and data receiver in the e-Health system for the data transmission is counterproductive as modification will be required for each new device added into the system. In this paper, an e-Health system with the Semantic Sensor Network (SSN) is proposed to address the device interoperability issue. In the proposed system, we have used IETF YANG for modeling the semantic e-Health data to represent the information of e-Health sensors. This modeling scheme helps in provisioning semantic interoperability between devices and expressing the sensing data in a user-friendly manner. For this purpose, we have developed an ontology for e-Health data that supports different styles of data formats. The ontology is defined in YANG for provisioning semantic interpretation of sensing data in the system by constructing meta-models of e-Health sensors. The proposed approach assists in the auto-configuration of eHealth sensors and querying the sensor network with semantic interoperability support for the e-Health system. PMID- 29461491 TI - Cancer Stem Cells, Bone and Tumor Microenvironment: Key Players in Bone Metastases. AB - Tumor mass is constituted by a heterogeneous group of cells, among which a key role is played by the cancer stem cells (CSCs), possessing high regenerative properties. CSCs directly metastasize to bone, since bone microenvironment represents a fertile environment that protects CSCs against the immune system, and maintains their properties and plasticity. CSCs can migrate from the primary tumor to the bone marrow (BM), due to their capacity to perform the epithelial-to mesenchymal transition. Once in BM, they can also perform the mesenchymal-to epithelial transition, allowing them to proliferate and initiate bone lesions. Another factor explaining the osteotropism of CSCs is their ability to recognize chemokine gradients toward BM, through the CXCL12-CXCR4 axis, also known to be involved in tumor metastasis to other organs. Moreover, the expression of CXCR4 is associated with the maintenance of CSCs' stemness, and CXCL12 expression by osteoblasts attracts CSCs to the BM niches. CSCs localize in the pre-metastatic niches, which are anatomically distinct regions within the tumor microenvironment and govern the metastatic progression. According to the stimuli received in the niches, CSCs can remain dormant for long time or outgrow from dormancy and create bone lesions. This review resumes different aspects of the CSCs' bone metastastic process and discusses available treatments to target CSCs. PMID- 29461495 TI - An Innovative Approach to Control Steel Reinforcement Corrosion by Self-Healing. AB - The corrosion of reinforced steel, and subsequent reinforced concrete degradation, is a major concern for infrastructure durability. New materials with specific, tailor-made properties or the establishment of optimum construction regimes are among the many approaches to improving civil structure performance. Ideally, novel materials would carry self-repairing or self-healing capacities, triggered in the event of detrimental influence and/or damage. Controlling or altering a material's behavior at the nano-level would result in traditional materials with radically enhanced properties. Nevertheless, nanotechnology applications are still rare in construction, and would break new ground in engineering practice. An approach to controlling the corrosion-related degradation of reinforced concrete was designed as a synergetic action of electrochemistry, cement chemistry and nanotechnology. This contribution presents the concept of the approach, namely to simultaneously achieve steel corrosion resistance and improved bulk matrix properties. The technical background and challenges for the application of polymeric nanomaterials in the field are briefly outlined in view of this concept, which has the added value of self healing. The credibility of the approach is discussed with reference to previously reported outcomes, and is illustrated via the results of the steel electrochemical responses and microscopic evaluations of the discussed materials. PMID- 29461494 TI - Less Waste on Waist Measurements: Determination of Optimal Waist Circumference Measurement Site to Predict Visceral Adipose Tissue in Postmenopausal Women with Obesity. AB - With obesity being a leading cause of preventable death, it is vital to understand how best to identify individuals with greater risk of metabolic disease, especially those with high visceral adipose tissue (VAT). This study aimed to determine whether three commonly used waist circumference (WC) measurement sites could provide accurate estimations of VAT, as determined by magnetic resonance imaging (MRI), which is a gold standard for measuring VAT, in postmenopausal women with obesity. VAT volume was measured by MRI of the total abdomen in 97 women aged 57.7 +/- 0.4 years (mean +/- SEM), mean body mass index 34.5 +/- 0.2 kg/m2. WC was measured at the midpoint between the lowest rib and the iliac crest (WCmid), the narrowest point of the torso (WCnarrow), and at the level of the umbilicus (WCumbilicus). WC differed significantly according to measurement site, with WCnarrow (102.1 +/- 0.7 cm) < WCmid (108.3 +/- 0.7 cm) < WCumbilicus (115.7 +/- 0.8 cm) (p < 0.001). WCmid, WCnarrow and WCumbilicus were all significantly correlated with VAT, as measured by MRI (r = 0.581, 0.563 and 0.390, respectively; p < 0.001 for all), but the relationships between WCmid or WCnarrow and VAT determined by MRI were stronger than for WCumbilicus. Measurement of either WCmid or WCnarrow provides valid estimates of VAT in postmenopausal women with obesity, with WCnarrow being favoured in light of its greater ease and speed of measurement in this population. PMID- 29461496 TI - Online Aerial Terrain Mapping for Ground Robot Navigation. AB - This work presents a collaborative unmanned aerial and ground vehicle system which utilizes the aerial vehicle's overhead view to inform the ground vehicle's path planning in real time. The aerial vehicle acquires imagery which is assembled into a orthomosaic and then classified. These terrain classes are used to estimate relative navigation costs for the ground vehicle so energy-efficient paths may be generated and then executed. The two vehicles are registered in a common coordinate frame using a real-time kinematic global positioning system (RTK GPS) and all image processing is performed onboard the unmanned aerial vehicle, which minimizes the data exchanged between the vehicles. This paper describes the architecture of the system and quantifies the registration errors between the vehicles.

This article reviews the population, physical-emotional and social concerns, and trajectory. PMID- 29461498 TI - Qualitative and Quantitative Phytochemical Analysis of Different Extracts from Thymus algeriensis Aerial Parts. AB - This study was performed to evaluate the metabolite recovery from different extraction methods applied to Thymusalgeriensis aerial parts. A high-performance liquid chromatographic method using photodiode array detector with gradient elution has been developed and validated for the simultaneous estimation of different phenolic compounds in the extracts and in their corresponding purified fractions. The experimental results show that microwave-assisted aqueous extraction for 15 min at 100 degrees C gave the most phenolics-enriched extract, reducing extraction time without degradation effects on bioactives. Sixteen compounds were identified in this extract, 11 phenolic compounds and five flavonoids, all known for their biological activities. Color analysis and determination of chlorophylls and carotenoids implemented the knowledge of the chemical profile of this plant. PMID- 29461499 TI - Pilot Testing a Photo-Based Food Diary in Nine- to Twelve- Year Old- Children from Dunedin, New Zealand. AB - The purpose of the study was to investigate if an Evernote app-based electronic food diary is an acceptable method to measure nutrient intake in children aged 9 12 years. A convenience sample of 16 nine- to twelve-year-olds from Dunedin, New Zealand, completed a paper-based food dairy on four days, followed by four more days using a photo-based diary on an iPod. This photo-based diary used a combination of photographs and short written descriptions of foods consumed. The photo-based diaries produced similar results to written diaries for all macronutrients and major micronutrients (e.g., calcium, fibre, vitamin C). Spearman correlation coefficients between the two methods for all nutrients, except sugars, were above 0.3. However, burden on researchers and participants was reduced for the photo-based diary, primarily due to the additional information obtained from photographs. Participating children needed less help from parents with completing the electronic diaries and preferred them to the paper version. This electronic diary is likely to be suitable, after additional formal validity testing, for use in measuring nutrient intake in children.

AB - The genus Streptomyces produces secondary metabolic compounds that are rich in biological activity. Many of these compounds are genetically encoded by large secondary metabolism biosynthetic gene clusters (smBGCs) such as polyketide synthases (PKS) and non-ribosomal peptide synthetases (NRPS) which are modular and can be highly repetitive. Due to the repeats, these gene clusters can be difficult to resolve using short read next generation datasets and are often quite poorly predicted using standard approaches. We have sequenced the genomes of 13 Streptomyces spp. strains isolated from shallow water and deep-sea sponges that display antimicrobial activities against a number of clinically relevant bacterial and yeast species. Draft genomes have been assembled and smBGCs have been identified using the antiSMASH (antibiotics and Secondary Metabolite Analysis Shell) web platform. We have compared the smBGCs amongst strains in the search for novel sequences conferring the potential to produce novel bioactive secondary metabolites. The strains in this study recruit to four distinct clades within the genus Streptomyces. The marine strains host abundant smBGCs which encode polyketides, NRPS, siderophores, bacteriocins and lantipeptides. The deep sea strains appear to be enriched with gene clusters encoding NRPS. Marine adaptations are evident in the sponge-derived strains which are enriched for genes involved in the biosynthesis and transport of compatible solutes and for heat-shock proteins. Streptomyces spp. from marine environments are a promising source of novel bioactive secondary metabolites as the abundance and diversity of smBGCs show high degrees of novelty. Sponge derived Streptomyces spp. isolates appear to display genomic adaptations to marine living when compared to terrestrial strains.

AB - With the introduction of cost-effective depth sensors, a tremendous amount of research has been devoted to studying human action recognition using 3D motion data. However, most existing methods work in an offline fashion, i.e., they operate on a segmented sequence. There are a few methods specifically designed for online action recognition, which continually predicts action labels as a stream sequence proceeds. In view of this fact, we propose a question: can we draw inspirations and borrow techniques or descriptors from existing offline methods, and then apply these to online action recognition? Note that extending offline techniques or descriptors to online applications is not straightforward, since at least two problems-including real-time performance and sequence segmentation-are usually not considered in offline action recognition. In this paper, we give a positive answer to the question. To develop applicable online action recognition methods, we carefully explore feature extraction, sequence segmentation, computational costs, and classifier selection. The effectiveness of the developed methods is validated on the MSR 3D Online Action dataset and the MSR Daily Activity 3D dataset.

AB - Sponges (Porifera) are recognized as aquatic multicellular organisms which developed an effective biochemical pathway over millions of years of evolution to produce both biologically active secondary metabolites and biopolymer-based skeletal structures. Among marine demosponges, only representatives of the Verongiida order are known to synthetize biologically active substances as well as skeletons made of structural polysaccharide chitin. The unique three dimensional (3D) architecture of such chitinous skeletons opens the widow for their recent applications as adsorbents, as well as scaffolds for tissue engineering and biomimetics. This study has the ambitious goal of monitoring other orders beyond Verongiida demosponges and finding alternative sources of naturally prestructured chitinous scaffolds; especially in those demosponge species which can be cultivated at large scales using marine farming conditions. Special attention has been paid to the demosponge Mycale euplectellioides(Heteroscleromorpha: Poecilosclerida: Mycalidae) collected in the Red Sea. For the first time, we present here a detailed study of the isolation of chitin from the skeleton of this sponge, as well as its identification using diverse bioanalytical tools. Calcofluor white staining, Fourier-transform Infrared Spcetcroscopy (FTIR), electrospray ionization mass spectrometry (ESI MS), scanning electron microscopy (SEM), and fluorescence microscopy, as well as a chitinase digestion assay were applied in order to confirm with strong evidence the finding of a-chitin in the skeleton of M. euplectellioides. We suggest that the discovery of chitin within representatives of the Mycale genus is a promising step in their evaluation of these globally distributed sponges as new renewable sources for both biologically active metabolites and chitin, which are of prospective use for pharmacology and biomaterials oriented biomedicine, respectively.

AB - The Sonogashira cross-coupling, a key step in the syntheses of the mGlu5 antagonists MMPEP and MTEP, provided an improved three-step method for the preparation of MMPEP in 62% overall yield. Using Spartan molecular modeling kit an explanation for the failure to employ analogues method in the synthesis of MTEP was sought. The DFT calculations indicated that meaningful isolated yields were obtained when the HOMO energy of the aryl halide was lower than the HOMO energy of the respective alkyne. PMID- 29461504 TI - Examining Differential Resilience Mechanisms by Comparing 'Tipping Points' of the Effects of Neighborhood Conditions on Anxiety by Race/Ethnicity. AB - Exposure to adverse environmental and social conditions affects physical and mental health through complex mechanisms. Different racial/ethnic (R/E) groups may be more or less vulnerable to the same conditions, and the resilience mechanisms that can protect them likely operate differently in each population. We investigate how adverse neighborhood conditions (neighborhood disorder, NDis) differentially impact mental health (anxiety, Anx) in a sample of white and Black (African American) young women from Southeast Texas, USA. We illustrate a simple yet underutilized segmented regression model where linearity is relaxed to allow for a shift in the strength of the effect with the levels of the predictor. We compare how these effects change within R/E groups with the level of the predictor, but also how the "tipping points," where the effects change in strength, may differ by R/E. We find with classic linear regression that neighborhood disorder adversely affects Black women's anxiety, while in white women the effect seems negligible. Segmented regressions show that the Ndis -> Anx effects in both groups of women appear to shift at similar levels, about one fifth of a standard deviation below the mean of NDis, but the effect for Black women appears to start out as negative, then shifts in sign, i.e., to increase anxiety, while for white women, the opposite pattern emerges. Our findings can aid in devising better strategies for reducing health disparities that take into account different coping or resilience mechanisms operating differentially at distinct levels of adversity. We recommend that researchers investigate when adversity becomes exceedingly harmful and whether this happens differentially in distinct populations, so that intervention policies can be planned to reverse conditions that are more amenable to change, in effect pushing back the overall social risk factors below such tipping points. PMID- 29461506 TI - Investigation of Sensitivities and Drift Effects of the Arrayed Flexible Chloride Sensor Based on RuO2/GO at Different Temperatures. AB - We investigate the temperature effect on sensing characteristics and drift effect of an arrayed flexible ruthenium dioxide (RuO2)/graphene oxide (GO) chloride sensor at different solution temperatures between 10 degrees C and 50 degrees C. The average sensor sensitivities according to our experimental results were 28.2 +/- 1.4 mV/pCl (10 degrees C), 42.5 +/- 2.0 mV/pCl (20 degrees C), 47.1 +/ 1.8 mV/pCl (30 degrees C), 54.1 +/- 2.01 mV/pCl (40 degrees C) and 46.6 +/- 2.1 mV/pCl (50 degrees C). We found the drift effects of an arrayed flexible RuO2/GO chloride sensor in a 1 M NaCl solution to be between 8.2 mV/h and 2.5 mV/h with solution temperatures from 10 degrees C to 50 degrees C. PMID- 29461505 TI - Exopolysaccharides from Marine and Marine Extremophilic Bacteria: Structures, Properties, Ecological Roles and Applications. AB - The marine environment is the largest aquatic ecosystem on Earth and it harbours microorganisms responsible for more than 50% of total biomass of prokaryotes in the world. All these microorganisms produce extracellular polymers that constitute a substantial part of the dissolved organic carbon, often in the form of exopolysaccharides (EPS). In addition, the production of these polymers is often correlated to the establishment of the biofilm growth mode, during which they are important matrix components. Their functions include adhesion and colonization of surfaces, protection of the bacterial cells and support for biochemical interactions between the bacteria and the surrounding environment. The aim of this review is to present a summary of the status of the research about the structures of exopolysaccharides from marine bacteria, including capsular, medium released and biofilm embedded polysaccharides. Moreover, ecological roles of these polymers, especially for those isolated from extreme ecological niches (deep-sea hydrothermal vents, polar regions, hypersaline ponds, etc.), are reported. Finally, relationships between the structure and the function of the exopolysaccharides are discussed.

AB - Both (+)-[18F]flubatine and its enantiomer (-)-[18F]flubatine are radioligands for the neuroimaging of alpha4beta2 nicotinic acetylcholine receptors (nAChRs) by positron emission tomography (PET). In a clinical study in patients with early Alzheimer's disease, (+)-[18F]flubatine ((+)-[18F]1) was examined regarding its metabolic fate, in particular by identification of degradation products detected in plasma and urine. The investigations included an in vivo study of (+) flubatine ((+)-1) in pigs and structural elucidation of formed metabolites by LC MS/MS. Incubations of (+)-1 and (+)-[18F]1 with human liver microsomes were performed to generate in vitro metabolites, as well as radiometabolites, which enabled an assignment of their structures by comparison of LC-MS/MS and radio HPLC data. Plasma and urine samples taken after administration of (+)-[18F]1 in humans were examined by radio-HPLC and, on the basis of results obtained in vitro and in vivo, formed radiometabolites were identified. PMID- 29461508 TI - Radical Polymerization of Alkyl 2-Cyanoacrylates. AB - Cyanoacrylates (CAs) are well-known fast-setting adhesives, which are sold as liquids in the presence of stabilizers. Rapid anionic polymerization on exposure to surface moisture is responsible for instant adhesion. The more difficult, but synthetically more useful radical polymerization is only possible under acidic conditions. Recommendations on the handling of CAs and the resulting polymers are provided herein. In this review article, after a general description of monomer and polymer properties, radical homo- and copolymerization studies are described, along with an overview of nanoparticle preparations. A summary of our recently reported radical polymerization of CAs, using reversible addition-fragmentation chain transfer (RAFT) polymerization, is provided. PMID- 29461509 TI - A Brief Note on the Magnetowetting of Magnetic Nanofluids on AAO Surfaces. AB - In magnetowetting, the material properties of liquid, surface morphology of solid, and applied external field are three major factors used to determine the wettability of a liquid droplet on a surface. For wetting measurements, an irregular or uneven surface could result in a significant experimental uncertainty. The periodic array with a hexagonal symmetry structure is an advantage of the anodic aluminum oxide (AAO) structure. This study presents the results of the wetting properties of magnetic nanofluid sessile droplets on surfaces of various AAO pore sizes under an applied external magnetic field. Stable, water-based magnetite nanofluids are prepared by combining the chemical co-precipitation with the sol-gel technique, and AAO surfaces are then generated by anodizing the aluminum sheet in the beginning. The influence of pore size and magnetic field gradient on the magnetowetting of magnetic nanofluids on AAO surfaces is then investigated by an optical test system. Experimental results show that increasing the processing voltage of AAO templates could result in enhanced non-wettability behavior; that is, the increase in AAO pore size could lead to the increase in contact angle. The contact angle could be reduced by the applied magnetic field gradient. In general, the magnetic field has a more significant effect at smaller AAO pore sizes. PMID- 29461510 TI - Genetic Variation and Hybridisation among Eight Species of kowhai (Sophora: Fabaceae) from New Zealand Revealed by Microsatellite Markers. AB - We analysed nine microsatellite markers for 626 individuals representing the geographic range of eight closely related endemic New Zealand species of Sophora. Structure analysis identified the optimal K value as seven, with samples identified as Sophorachathamica, Sophorafulvida, Sophoralongicarinata, and Sophoraprostrata retrieved as well-defined groups. The remaining samples formed less resolved groups referable to Sophoratetraptera and Sophoragodleyi, with Sophoramicrophylla and Sophoramolloyi forming the seventh group. Our data suggest that considerable admixture occurs and this is most likely the result of hybridisation or introgression. S.fulvida shows admixture with the sympatric S.chathamica, and the widespread S.microphylla exhibits admixture with the sympatric S.godleyi, S.molloyi, and S.tetraptera. PMID- 29461512 TI - Delineation of Novel Autosomal Recessive Mutation in GJA3 and Autosomal Dominant Mutations in GJA8 in Pakistani Congenital Cataract Families. AB - Congenital cataract is a clinically and genetically heterogeneous disease. The present study was undertaken to find the genetic cause of congenital cataract families. DNA samples of a large consanguineous Pakistani family were genotyped with a high resolution single nucleotide polymorphism Illumina microarray. Homozygosity mapping identified a homozygous region of 4.4 Mb encompassing the gene GJA3. Sanger sequence analysis of the GJA3 gene revealed a novel homozygous variant c.950dup p.(His318ProfsX8) segregating in an autosomal recessive (AR) manner. The previously known mode of inheritance for GJA3 gene mutations in cataract was autosomal dominant (AD) only. The screening of additional probands (n = 41) of cataract families revealed a previously known mutation c.56C>T p.(Thr19Met) in GJA3 gene. In addition, sequencing of the exon-intron boundaries of the GJA8 gene in 41 cataract probands revealed two additional mutations: a novel c.53C>T p.(Ser18Phe) and a known c.175C>G p.(Pro59Ala) mutation, both co segregating with the disease phenotype in an AD manner. All these mutations are predicted to be pathogenic by in silico analysis and were absent in the control databases. In conclusion, results of the current study enhance our understanding of the genetic basis of cataract, and identified the involvement of the GJA3 in the disease etiology in both AR and AD manners. PMID- 29461513 TI - Inter-comparison of multiple statistically downscaled climate datasets for the Pacific Northwest, USA. AB - Statistically downscaled climate data have been widely used to explore possible impacts of climate change in various fields of study. Although many studies have focused on characterizing differences in the downscaling methods, few studies have evaluated actual downscaled datasets being distributed publicly. Spatially focusing on the Pacific Northwest, we compare five statistically downscaled climate datasets distributed publicly in the US: ClimateNA, NASA NEX-DCP30, MACAv2-METDATA, MACAv2-LIVNEH and WorldClim. We compare the downscaled projections of climate change, and the associated observational data used as training data for downscaling. We map and quantify the variability among the datasets and characterize the spatio-temporal patterns of agreement and disagreement among the datasets. Pair-wise comparisons of datasets identify the coast and high-elevation areas as areas of disagreement for temperature. For precipitation, high-elevation areas, rainshadows and the dry, eastern portion of the study area have high dissimilarity among the datasets. By spatially aggregating the variability measures into watersheds, we develop guidance for selecting datasets within the Pacific Northwest climate change impact studies. PMID- 29461511 TI - Roles of A-Kinase Anchoring Proteins and Phosphodiesterases in the Cardiovascular System. AB - A-kinase anchoring proteins (AKAPs) and cyclic nucleotide phosphodiesterases (PDEs) are essential enzymes in the cyclic adenosine 3'-5' monophosphate (cAMP) signaling cascade. They establish local cAMP pools by controlling the intensity, duration and compartmentalization of cyclic nucleotide-dependent signaling. Various members of the AKAP and PDE families are expressed in the cardiovascular system and direct important processes maintaining homeostatic functioning of the heart and vasculature, e.g., the endothelial barrier function and excitation contraction coupling. Dysregulation of AKAP and PDE function is associated with pathophysiological conditions in the cardiovascular system including heart failure, hypertension and atherosclerosis. A number of diseases, including autosomal dominant hypertension with brachydactyly (HTNB) and type I long-QT syndrome (LQT1), result from mutations in genes encoding for distinct members of the two classes of enzymes. This review provides an overview over the AKAPs and PDEs relevant for cAMP compartmentalization in the heart and vasculature and discusses their pathophysiological role as well as highlights the potential benefits of targeting these proteins and their protein-protein interactions for the treatment of cardiovascular diseases. PMID- 29461515 TI - Epidemiological characteristics of human-infective RNA viruses. AB - RNA viruses are a major threat to human health. Here, based on extensive literature searches carried out over a period of 18 years, we provide a catalogue of all 214 known human-infective RNA virus species. We link these viruses to metadata for a number of traits that influence their epidemiology, including the date of the first report of human infection, transmissibility in human populations, transmission route(s) and host range. This database can be used in comparative studies of human-infective RNA viruses to identify the characteristics of viruses most likely to pose the greatest public health threat, both now and in the future. PMID- 29461514 TI - A large, open source dataset of stroke anatomical brain images and manual lesion segmentations. AB - Stroke is the leading cause of adult disability worldwide, with up to two-thirds of individuals experiencing long-term disabilities. Large-scale neuroimaging studies have shown promise in identifying robust biomarkers (e.g., measures of brain structure) of long-term stroke recovery following rehabilitation. However, analyzing large rehabilitation-related datasets is problematic due to barriers in accurate stroke lesion segmentation. Manually-traced lesions are currently the gold standard for lesion segmentation on T1-weighted MRIs, but are labor intensive and require anatomical expertise. While algorithms have been developed to automate this process, the results often lack accuracy. Newer algorithms that employ machine-learning techniques are promising, yet these require large training datasets to optimize performance. Here we present ATLAS (Anatomical Tracings of Lesions After Stroke), an open-source dataset of 304 T1-weighted MRIs with manually segmented lesions and metadata. This large, diverse dataset can be used to train and test lesion segmentation algorithms and provides a standardized dataset for comparing the performance of different segmentation methods. We hope ATLAS release 1.1 will be a useful resource to assess and improve the accuracy of current lesion segmentation methods. PMID- 29461517 TI - Arthropods dataset from different genetically modified maize events and associated controls. AB - Arthropods from four genetically modified (GM) maize hybrids (coleopteran resistant, coleopteran and lepidopteran resistant, lepidopteran resistant+herbicide tolerant and coleopteran resistant and herbicide tolerant) and non-GM varieties were sampled during a two-year field assessment. A total number of 363 555 arthropod individuals were collected. This represents the most comprehensive arthropod dataset from GM maize, and together with weed data, is reasonable to determine functional groups of arthropods and interactions between species. Trophic groups identified from both phytophagous and predatory arthropods were previously considered non-target organisms on which possible detrimental effects of Bacillus thuringiensis (Bt) toxins may have been directly (phytophagous species) or indirectly (predators) detected. The high number of individuals and species and their dynamics through the maize growing season can predict that interactions are highly correlational, and can thus be considered a useful tool to assess potential deleterious effects of Bt toxins on non-target organisms, serving to develop biosafety risk hypotheses for invertebrates exposed to GM maize plants. PMID- 29461516 TI - A database of chlorophyll a in Australian waters. AB - Chlorophyll a is the most commonly used indicator of phytoplankton biomass in the marine environment. It is relatively simple and cost effective to measure when compared to phytoplankton abundance and is thus routinely included in many surveys. Here we collate 173, 333 records of chlorophyll a collected since 1965 from Australian waters gathered from researchers on regular coastal monitoring surveys and ocean voyages into a single repository. This dataset includes the chlorophyll a values as measured from samples analysed using spectrophotometry, fluorometry and high performance liquid chromatography (HPLC). The Australian Chlorophyll a database is freely available through the Australian Ocean Data Network portal (https://portal.aodn.org.au/). These data can be used in isolation as an index of phytoplankton biomass or in combination with other data to provide insight into water quality, ecosystem state, and relationships with other trophic levels such as zooplankton or fish. PMID- 29461518 TI - De novo design and engineering of non-ribosomal peptide synthetases. AB - Peptides derived from non-ribosomal peptide synthetases (NRPSs) represent an important class of pharmaceutically relevant drugs. Methods to generate novel non ribosomal peptides or to modify peptide natural products in an easy and predictable way are therefore of great interest. However, although the overall modular structure of NRPSs suggests the possibility of adjusting domain specificity and selectivity, only a few examples have been reported and these usually show a severe drop in production titre. Here we report a new strategy for the modification of NRPSs that uses defined exchange units (XUs) and not modules as functional units. XUs are fused at specific positions that connect the condensation and adenylation domains and respect the original specificity of the downstream module to enable the production of the desired peptides. We also present the use of internal condensation domains as an alternative to other peptide-chain-releasing domains for the production of cyclic peptides. PMID- 29461519 TI - Evaluating differences in the active-site electronics of supported Au nanoparticle catalysts using Hammett and DFT studies. AB - Supported metal catalysts, which are composed of metal nanoparticles dispersed on metal oxides or other high-surface-area materials, are ubiquitous in industrially catalysed reactions. Identifying and characterizing the catalytic active sites on these materials still remains a substantial challenge, even though it is required to guide rational design of practical heterogeneous catalysts. Metal-support interactions have an enormous impact on the chemistry of the catalytic active site and can determine the optimum support for a reaction; however, few direct probes of these interactions are available. Here we show how benzyl alcohol oxidation Hammett studies can be used to characterize differences in the catalytic activity of Au nanoparticles hosted on various metal-oxide supports. We combine reactivity analysis with density functional theory calculations to demonstrate that the slope of experimental Hammett plots is affected by electron donation from the underlying oxide support to the Au particles. PMID- 29461520 TI - Pt/Cu single-atom alloys as coke-resistant catalysts for efficient C-H activation. AB - The recent availability of shale gas has led to a renewed interest in C-H bond activation as the first step towards the synthesis of fuels and fine chemicals. Heterogeneous catalysts based on Ni and Pt can perform this chemistry, but deactivate easily due to coke formation. Cu-based catalysts are not practical due to high C-H activation barriers, but their weaker binding to adsorbates offers resilience to coking. Using Pt/Cu single-atom alloys (SAAs), we examine C-H activation in a number of systems including methyl groups, methane and butane using a combination of simulations, surface science and catalysis studies. We find that Pt/Cu SAAs activate C-H bonds more efficiently than Cu, are stable for days under realistic operating conditions, and avoid the problem of coking typically encountered with Pt. Pt/Cu SAAs therefore offer a new approach to coke resistant C-H activation chemistry, with the added economic benefit that the precious metal is diluted at the atomic limit.

In many instances, enzymes that participate in reaction cascades have been shown to assemble into metabolons in response to the presence of the substrate for the first enzyme. However, what triggers metabolon formation has remained an open question. Through a combination of theory and experiments, we show that enzymes in a cascade can assemble via chemotaxis. We apply microfluidic and fluorescent spectroscopy techniques to study the coordinated movement of the first four enzymes of the glycolysis cascade: hexokinase, phosphoglucose isomerase, phosphofructokinase and aldolase. We show that each enzyme independently follows its own specific substrate gradient, which in turn is produced by the preceding enzymatic reaction. Furthermore, we find that the chemotactic assembly of enzymes occurs even under cytosolic crowding conditions. PMID- 29461523 TI - Evolving artificial metalloenzymes via random mutagenesis. AB - Random mutagenesis has the potential to optimize the efficiency and selectivity of protein catalysts without requiring detailed knowledge of protein structure; however, introducing synthetic metal cofactors complicates the expression and screening of enzyme libraries, and activity arising from free cofactor must be eliminated. Here we report an efficient platform to create and screen libraries of artificial metalloenzymes (ArMs) via random mutagenesis, which we use to evolve highly selective dirhodium cyclopropanases. Error-prone PCR and combinatorial codon mutagenesis enabled multiplexed analysis of random mutations, including at sites distal to the putative ArM active site that are difficult to identify using targeted mutagenesis approaches. Variants that exhibited significantly improved selectivity for each of the cyclopropane product enantiomers were identified, and higher activity than previously reported ArM cyclopropanases obtained via targeted mutagenesis was also observed. This improved selectivity carried over to other dirhodium-catalysed transformations, including N-H, S-H and Si-H insertion, demonstrating that ArMs evolved for one reaction can serve as starting points to evolve catalysts for others. PMID- 29461524 TI - Asymmetric transfer hydrogenation by synthetic catalysts in cancer cells. AB - Catalytic anticancer metallodrugs active at low doses could minimize side effects, introduce novel mechanisms of action that combat resistance and widen the spectrum of anticancer-drug activity. Here we use highly stable chiral half sandwich organometallic Os(II) arene sulfonyl diamine complexes, [Os(arene)(TsDPEN)] (TsDPEN, N-(p-toluenesulfonyl)-1,2-diphenylethylenediamine), to achieve a highly enantioselective reduction of pyruvate, a key intermediate in metabolic pathways. Reduction is shown both in aqueous model systems and in human cancer cells, with non-toxic concentrations of sodium formate used as a hydride source. The catalytic mechanism generates selectivity towards ovarian cancer cells versus non-cancerous fibroblasts (both ovarian and lung), which are commonly used as models of healthy proliferating cells. The formate precursor N formylmethionine was explored as an alternative to formate in PC3 prostate cancer cells, which are known to overexpress a deformylase enzyme. Transfer hydrogenation catalysts that generate reductive stress in cancer cells offer a new approach to cancer therapy. PMID- 29461525 TI - Transferring the entatic-state principle to copper photochemistry. AB - The entatic state denotes a distorted coordination geometry of a complex from its typical arrangement that generates an improvement to its function. The entatic state principle has been observed to apply to copper electron-transfer proteins and it results in a lowering of the reorganization energy of the electron transfer process. It is thus crucial for a multitude of biochemical processes, but its importance to photoactive complexes is unexplored. Here we study a copper complex-with a specifically designed constraining ligand geometry-that exhibits metal-to-ligand charge-transfer state lifetimes that are very short. The guanidine-quinoline ligand used here acts on the bis(chelated) copper(I) centre, allowing only small structural changes after photoexcitation that result in very fast structural dynamics. The data were collected using a multimethod approach that featured time-resolved ultraviolet-visible, infrared and X-ray absorption and optical emission spectroscopy. Through supporting density functional calculations, we deliver a detailed picture of the structural dynamics in the picosecond-to-nanosecond time range. PMID- 29461526 TI - Complex supramolecular interfacial tessellation through convergent multi-step reaction of a dissymmetric simple organic precursor. AB - Interfacial supramolecular self-assembly represents a powerful tool for constructing regular and quasicrystalline materials. In particular, complex two dimensional molecular tessellations, such as semi-regular Archimedean tilings with regular polygons, promise unique properties related to their nontrivial structures. However, their formation is challenging, because current methods are largely limited to the direct assembly of precursors, that is, where structure formation relies on molecular interactions without using chemical transformations. Here, we have chosen ethynyl-iodophenanthrene (which features dissymmetry in both geometry and reactivity) as a single starting precursor to generate the rare semi-regular (3.4.6.4) Archimedean tiling with long-range order on an atomically flat substrate through a multi-step reaction. Intriguingly, the individual chemical transformations converge to form a symmetric alkynyl-Ag alkynyl complex as the new tecton in high yields. Using a combination of microscopy and X-ray spectroscopy tools, as well as computational modelling, we show that in situ generated catalytic Ag complexes mediate the tecton conversion. PMID- 29461527 TI - Nonribosomal biosynthesis of backbone-modified peptides. AB - Biosynthetic modification of nonribosomal peptide backbones represents a potentially powerful strategy to modulate the structure and properties of an important class of therapeutics. Using a high-throughput assay for catalytic activity, we show here that an L-Phe-specific module of an archetypal nonribosomal peptide synthetase can be reprogrammed to accept and process the backbone-modified amino acid (S)-beta-Phe with near-native specificity and efficiency. A co-crystal structure with a non-hydrolysable aminoacyl-AMP analogue reveals the origins of the 40,000-fold alpha/beta-specificity switch, illuminating subtle but precise remodelling of the active site. When the engineered catalyst was paired with downstream module(s), (S)-beta-Phe-containing peptides were produced at preparative scale in vitro (~1 mmol) and high titres in vivo (~100 mg l-1), highlighting the potential of biosynthetic pathway engineering for the construction of novel nonribosomal beta-frameworks. PMID- 29461528 TI - Engineered modular biomaterial logic gates for environmentally triggered therapeutic delivery. AB - The successful transport of drug- and cell-based therapeutics to diseased sites represents a major barrier in the development of clinical therapies. Targeted delivery can be mediated through degradable biomaterial vehicles that utilize disease biomarkers to trigger payload release. Here, we report a modular chemical framework for imparting hydrogels with precise degradative responsiveness by using multiple environmental cues to trigger reactions that operate user programmable Boolean logic. By specifying the molecular architecture and connectivity of orthogonal stimuli-labile moieties within material cross-linkers, we show selective control over gel dissolution and therapeutic delivery. To illustrate the versatility of this methodology, we synthesized 17 distinct stimuli-responsive materials that collectively yielded all possible YES/OR/AND logic outputs from input combinations involving enzyme, reductant and light. Using these hydrogels we demonstrate the first sequential and environmentally stimulated release of multiple cell lines in well-defined combinations from a material. We expect these platforms will find utility in several diverse fields including drug delivery, diagnostics and regenerative medicine. PMID- 29461529 TI - Biosynthesis: Reprogramming assembly lines. PMID- 29461530 TI - Ultrafast dynamics of low-energy electron attachment via a non-valence correlation-bound state. AB - The primary electron-attachment process in electron-driven chemistry represents one of the most fundamental chemical transformations with wide-ranging importance in science and technology. However, the mechanistic detail of the seemingly simple reaction of an electron and a neutral molecule to form an anion remains poorly understood, particularly at very low electron energies. Here, time resolved photoelectron imaging was used to probe the electron-attachment process to a non-polar molecule using time-resolved methods. An initially populated diffuse non-valence state of the anion that is bound by correlation forces evolves coherently in ~30 fs into a valence state of the anion. The extreme efficiency with which the correlation-bound state serves as a doorway state for low-energy electron attachment explains a number of electron-driven processes, such as anion formation in the interstellar medium and electron attachment to fullerenes. PMID- 29461531 TI - Endothermic singlet fission is hindered by excimer formation. AB - Singlet fission is a process whereby two triplet excitons can be produced from one photon, potentially increasing the efficiency of photovoltaic devices. Endothermic singlet fission is desired for a maximum energy-conversion efficiency, and such systems have been considered to form an excimer-like state with multiexcitonic character prior to the appearance of triplets. However, the role of the excimer as an intermediate has, until now, been unclear. Here we show, using 5,12-bis((triisopropylsilyl)ethynyl)tetracene in solution as a prototypical example, that, rather than acting as an intermediate, the excimer serves to trap excited states to the detriment of singlet-fission yield. We clearly demonstrate that singlet fission and its conjugate process, triplet triplet annihilation, occur at a longer intermolecular distance than an excimer intermediate would impute. These results establish that an endothermic singlet fission material must be designed to avoid excimer formation, thus allowing singlet fission to reach its full potential in enhancing photovoltaic energy conversion.

AB - The reactivity of uranium compounds towards small molecules typically occurs through stoichiometric rather than catalytic processes. Examples of uranium catalysts reacting with water are particularly scarce, because stable uranyl groups form that preclude the recovery of the uranium compound. Recently, however, an arene-anchored, electron-rich uranium complex has been shown to facilitate the electrocatalytic formation of H2 from H2O. Here, we present the precise role of uranium-arene delta bonding in intermediates of the catalytic cycle, as well as details of the atypical two-electron oxidative addition of H2O to the trivalent uranium catalyst. Both aspects were explored by synthesizing mid and high-valent uranium-oxo intermediates and by performing comparative studies with a structurally related complex that cannot engage in delta bonding. The redox activity of the arene anchor and a covalent delta-bonding interaction with the uranium ion during H2 formation were supported by density functional theory analysis. Detailed insight into this catalytic system may inspire the design of ligands for new uranium catalysts. PMID- 29461534 TI - Correction. AB - This corrects the article DOI: 10.1038/nchem.2914.

AB - Translocation of lipid II across the cytoplasmic membrane is essential in peptidoglycan biogenesis. Although most steps are understood, identifying the lipid II flippase has yielded conflicting results, and the lipid II binding properties of two candidate flippases-MurJ and FtsW-remain largely unknown. Here we apply native mass spectrometry to both proteins and characterize lipid II binding. We observed lower levels of lipid II binding to FtsW compared to MurJ, consistent with MurJ having a higher affinity. Site-directed mutagenesis of MurJ suggests that mutations at A29 and D269 attenuate lipid II binding to MurJ, whereas chemical modification of A29 eliminates binding. The antibiotic ramoplanin dissociates lipid II from MurJ, whereas vancomycin binds to form a stable complex with MurJ:lipid II. Furthermore, we reveal cardiolipins associate with MurJ but not FtsW, and exogenous cardiolipins reduce lipid II binding to MurJ. These observations provide insights into determinants of lipid II binding to MurJ and suggest roles for endogenous lipids in regulating substrate binding.

AB - The search for improved energy-storage materials has revealed Li- and Na-rich intercalation compounds as promising high-capacity cathodes. They exhibit capacities in excess of what would be expected from alkali-ion removal/reinsertion and charge compensation by transition-metal (TM) ions. The additional capacity is provided through charge compensation by oxygen redox chemistry and some oxygen loss. It has been reported previously that oxygen redox occurs in O 2p orbitals that interact with alkali ions in the TM and alkali-ion layers (that is, oxygen redox occurs in compounds containing Li+-O(2p)-Li+ interactions). Na2/3[Mg0.28Mn0.72]O2 exhibits an excess capacity and here we show that this is caused by oxygen redox, even though Mg2+ resides in the TM layers rather than alkali-metal (AM) ions, which demonstrates that excess AM ions are not required to activate oxygen redox. We also show that, unlike the alkali-rich compounds, Na2/3[Mg0.28Mn0.72]O2 does not lose oxygen. The extraction of alkali ions from the alkali and TM layers in the alkali-rich compounds results in severely underbonded oxygen, which promotes oxygen loss, whereas Mg2+ remains in Na2/3[Mg0.28Mn0.72]O2, which stabilizes oxygen.

AB - Changing the vegetation cover of the Earth has impacts on the biophysical properties of the surface and ultimately on the local climate. Depending on the specific type of vegetation change and on the background climate, the resulting competing biophysical processes can have a net warming or cooling effect, which can further vary both spatially and seasonally. Due to uncertain climate impacts and the lack of robust observations, biophysical effects are not yet considered in land-based climate policies. Here we present a dataset based on satellite remote sensing observations that provides the potential changes i) of the full surface energy balance, ii) at global scale, and iii) for multiple vegetation transitions, as would now be required for the comprehensive evaluation of land based mitigation plans. We anticipate that this dataset will provide valuable information to benchmark Earth system models, to assess future scenarios of land cover change and to develop the monitoring, reporting and verification guidelines required for the implementation of mitigation plans that account for biophysical land processes. PMID- 29461537 TI - Palladium-catalysed anti-Markovnikov selective oxidative amination. AB - In recent years, the synthesis of amines and other nitrogen-containing motifs has been a major area of research in organic chemistry because they are widely represented in biologically active molecules. Current strategies rely on a multistep approach and require one reactant to be activated prior to the carbon nitrogen bond formation. This leads to a reaction inefficiency and functional group intolerance. As such, a general approach to the synthesis of nitrogen containing compounds from readily available and benign starting materials is highly desirable. Here we present a palladium-catalysed oxidative amination reaction in which the addition of the nitrogen occurs at the less-substituted carbon of a double bond, in what is known as anti-Markovnikov selectivity. Alkenes are shown to react with imides in the presence of a palladate catalyst to generate the terminal imide through trans-aminopalladation. Subsequently, olefin isomerization occurs to afford the thermodynamically favoured products. Both the scope of the transformation and mechanistic investigations are reported.

AB - The quality of care for patients with cleft lip and palate is extremely variable across the world. Treatment protocols differ and methods of data registration are not uniform. Improving this care by means of comparative research is challenging. The best treatment programmes can be identified by uniformly registering patient orientated outcomes and comparing the outcomes with those of other treatment centres. That knowledge can be used to improve one's own care. An international team consisting of specialists and cleft lip and palate patients has developed a set of outcome measures that are considered by patients to be most important. This team is coordinated by the International Consortium of Health Outcomes Measurement (ICHOM). The cleft lip and palate outcome set can be used by all centres worldwide in following up on cleft lip and palate patients. In the Erasmus Medical Centre in Rotterdam, the 'Zorgmonitor Schisis' (Care Monitor Cleft Lip and Palate) has been built, an application in which these outcome measures are collected at fixed times. Implementing this set of outcome measures in other cleft lip and palate treatment centres and using the outcomes as (inter)national benchmarks will result in transparency and the improvement of the treatment of cleft lip and palate worldwide. PMID- 29461540 TI - [Juvenile idiopathic arthritis]. AB - Juvenile idiopathic arthritis (JIA) is the most common cause of chronic inflammation of the joints in childhood. Currently, JIA is divided into 7 subtypes, distinguished on the basis of the symptoms present in the first six months of the illness. Pharmacological treatment is different for every subtype. With all forms of JIA, dental problems can occur. These can include an increasing incidence of dental caries, stomatitis with the use of methotrexate, oral candidiasis with the use of immunosuppressive medication and temporal mandibular joint (TMJ) arthritis. The detection of TMJ arthritis seems to be especially difficult in daily practice. Dentists could play a role in identifying the TMJ complication in children with JIA. PMID- 29461541 TI - [The use of scientific journals and professional periodicals by Dutch dental students]. AB - In the present study, the extent to which dental students in Amsterdam, Groningen and Nijmegen consult scientific journals and professional periodicals was explored by means of a digital questionnaire. 333 dental students (20% response rate) participated in this study, 69% of whom had experience in conducting scientific research. 65% of the students had a subscription to a dental journal. Of the Dutch-language dental journals, the 'Nederlands Tijdschrift voor Tandheelkunde' [Netherlands Journal for Dentistry] and the 'Nederlands Tandartsenblad' [Dutch Dentists' Journal] are frequently consulted journals. International publications are consulted especially by masters students, although less frequently than Dutch dental journals. The study revealed that 77% of the students consider it important that attention is paid to the development of scientific skills early in the dental curriculum in order to adequately prepare students to select and interpret publications. PMID- 29461542 TI - [A study to determine possible success variables in the treatment of gag reflex patients]. AB - A disproportionately sensitive gag reflex can hamper adequate dental treatment. Because an evidence-based treatment for this condition is lacking at this moment, a study of patients and success variables for the treatment was carried out. The study was based on the clinical records of and interviews with 40 people who had been treated in a Centre for Special Dental Care (CBT) because of extreme gag problems two years earlier. It was found that the gag complaints of half of the respondents had disappeared or become manageable, while those of the other half had not changed. It did not matter which intervention had been adopted. In order to determine how patients can best be treated and which patients can best be treated, research among larger patient samples is needed. PMID- 29461543 TI - [External cervical root resorption]. AB - External cervical root resorption begins at the root surface as result of odontoclastic activity in the cervical area and is progressive in character. The pulp is only affected at a later stage of the process. The aetiology and pathogenesis of external cervical root resorption is not fully understood. Possible predisposing factors are, among others, orthodontic treatment, trauma, internal bleaching, damaged cemento-enamel junction, bruxism and hypoxia. A 'pink spot' often is the first clinical sign and a two-dimensional radiograph usually presents an amorphous radiolucency with undefined borders. Cone-beam computed tomography is an emerging technique aiding the diagnosis of and prognosis and treatment plans for external root resorption. An external or internal treatment approach can be chosen, depending on the size of the defect. PMID- 29461544 TI - [A PhD completed. Bilateral sagittal split osteotomy: risk factors for complications and predictability of the splitter-separator technique]. AB - Bilateral sagittal split osteotomy (BSSO) is a surgical technique to correct hypoplasia, hyperplasia or asymmetry of the mandible. The risk of complications associated with BSSO with splitter and separators, the so-called splitter separator technique, and the predictability of this technique were analysed. The average incidence of complications associated with classic BSSO techniques was determined by a review of the literature. With classic techniques, a bad split occurred in 2.3% of the operated sides, removal of osteosynthesis material on account of complaints in 11.2% of patients, and permanent neurosensory disturbances in the area of the mental nerve in 33.9% of patients. The incidence of complications for BSSO with splitter and separators is a bad split in 2.0% of the operated sides, necessary removal of osteosynthesis material in 5.6% of patients, and permanent neurosensory disturbances of the lower lip in 9.9% of patients. Removal of the third molars during BSSO may result in an increased chance of bad split but does not increase the risk of other complications. In conclusion, BSSO with splitter and separators is a reliable technique, with a remarkably low incidence of permanent neurosensory disturbances of the lower lip.

AB - Organic pollutants have been monitored in the atmosphere of the Great Lake Basin (GLB) since the 1990s in support of the Canada-US Great Lakes Water Quality Agreement and to determine the effectiveness of source reduction measures and factors influencing air concentrations. Air samples were collected between 2005 and 2014 at three sites with different geographical characteristics (Burnt Island, Egbert and Point Petre) in the Canadian GLB using high-volume air samplers and the air samples were analyzed for polybrominated diphenyl ethers (PBDEs) and several other non-PBDE halogenated flame retardants (HFRs). Spatial and temporal trends of total concentrations of HFRs were examined. BDE-47, BDE 99, and BDE-209 were the dominant PBDE congeners found at the three sites. For the non-PBDE HFRs, allyl 2,4,6-tribromophenyl ether (TBP-AE), hexabromobenzene (HBBz), pentabromotoluene (PBT), anti-dechlorane plus (anti-DDC-CO) and syn dechlorane plus (syn-DDC-CO) were frequently detected. High atmospheric concentrations of PBDEs were found at the Egbert site with a larger population, while lower levels of PBDEs were detected at Point Petre, which is close to urban centers where control measures are in place. The strong temperature dependence of air concentrations indicates that volatilization from local sources influences atmospheric concentrations of BDE-28 and BDE-47 at Point Petre and Burnt Island, while long-range atmospheric transport (LRAT) was important for BDE-99. However, a weaker correlation was observed between air concentrations and ambient temperature for non-PBDE HFRs such as TBP-AE and HBBz. Atmospheric PBDE concentrations are decreasing slowly, with half-lives in the range of 2-16 years. Faster declining trends of PBDEs were observed at Point Petre rather than at Burnt Island. As Point Petre is closer to urban centers, faster declining trends may reflect the phase out of technical BDE mixtures in urban centers while LRAT influences the air concentrations at Burnt Island. The levels of syn-DDC-CO and anti-DDC-CO are decreasing at Point Petre and the levels of other non-PBDE HFRs such as TBP-AE, PBT and HBBz are increasing. Long-term declining trends of PBDEs suggest that regulatory efforts to reduce emissions to the GLB environment have been effective but that continuous measurements are required to gain a better understanding of the trends of emerging chemicals in the atmosphere of the GLB.

AB - The effect of oxidative treatments on the depostion of cobalt nanocrystals (Co NC) onto a support and subsequent ligand removal was investigated. Deposition of epsilon-cobalt NC led to extensive clustering of NC and low Fischer-Tropsch synthesis activity. Low-temperature oxidation of epsilon-cobalt NC resulted in a very uniform CoO-NC distribution and high activity whereas high-temperature oxidation to Co3O4 led to less uniform NC distributions and lower activity. PMID- 29461547 TI - Polydiacetylene liposomes with phenylboronic acid tags: a fluorescence turn-on sensor for sialic acid detection and cell-surface glycan imaging. AB - Sialic acid (SA) located at the terminal end of glycans on cell membranes has been shown to play an important yet distinctive role in various biological and pathological processes. Effective methods for the facile, sensitive and in situ analysis of SA on living cell surfaces are of great significance in terms of clinical diagnostics and therapeutics. Here, a new polydiacetylene (PDA) liposome based sensor system bearing phenylboronic acid (PBA) and 1,8-naphthalimide derived fluorophore moieties was developed as a fluorescence turn-on sensor for the detection of free SA in aqueous solution and the in situ imaging of SA terminated glycans on living cell surfaces. In the sensor system, three diacetylene monomers, PCDA-pBA, PCDA-Nap and PCDA-EA, were designed and synthesized to construct the composite PDA liposome sensor. The monomer PCDA-pBA modified with PBA molecules was employed as a receptor for SA recognition, while the monomer PCDA-Nap containing a 1,8-naphthalimide derivative fluorophore was used for fluorescence signaling. When the composite PDA liposomes were formed, the energy transfer between the fluorophore and the conjugated backbone could directly quench the fluorescence of the fluorophore. In the presence of additional SA or SA abundant cells, the strong binding of SA with PBA moieties disturbed the pendent side chain conformation, resulting in the fluorescence restoration of the fluorophore. The proposed methods realized the fluorescence turn-on detection of free SA in aqueous solution and the in situ imaging of SA on living MCF-7 cell surfaces. This work provides a new potential tool for simple and selective analysis of SA on living cell membranes. PMID- 29461548 TI - Direct measurement of surface charge distribution in phase separating supported lipid bilayers. AB - The local surface charge density of the cell membrane influences regulation and localization of membrane proteins. The local surface charge density could, until recently, not be measured directly under physiological conditions, and it was largely a hypothetical yet very important parameter. Here we use unsaturated lipids of a distinct charge (DOTAP, DOPC, and DOPG) and a neutral fully saturated lipid (DPPC) to create model membranes with phase separating domains of a defined charge. We then apply quantitative surface charge microscopy (QSCM) to investigate the local surface charge density; this is a technique based on a scanning ion conductance microscope (SICM) capable of measuring surface charge density with nanoscale lateral resolution. We are able to clearly distinguish lipid domains from charge and topography in all three model membranes. The measured surface charge densities furthermore reveal that disordered domains formed by charged lipids are in fact not only impure, but also incorporate uncharged saturated lipids. We estimate that at least 30% of disordered domains in DOPG : DPPC and DOTAP : DPPC will be DPPC. These ratios could present a limit for the formation of charged domains in lipid membranes.

AB - A Pd(ii)-catalyzed asymmetric 1,6-addition of arylboronic acids to Meldrum's acid derived dienes was developed. A new substituted In-Pyrox ligand was designed to enable this reaction with high enantioselectivity via a remote steric effect. A series of Meldrum's acid-derived dienes and arylboronic acids were tolerable to the reaction conditions, giving the desired adducts in moderate to high yields with good enantioselectivities (up to 96% ee). This reaction provides the first method of Pd(ii)-catalyzed asymmetric 1,6-conjugate addition of arylboron. PMID- 29461549 TI - Force determination in lateral magnetic tweezers combined with TIRF microscopy. AB - Combining single-molecule techniques with fluorescence microscopy has attracted much interest because it allows the correlation of mechanical measurements with directly visualized DNA : protein interactions. In particular, its combination with total internal reflection fluorescence microscopy (TIRF) is advantageous because of the high signal-to-noise ratio this technique achieves. This, however, requires stretching long DNA molecules across the surface of a flow cell to maximize polymer exposure to the excitation light. In this work, we develop a module to laterally stretch DNA molecules at a constant force, which can be easily implemented in regular or combined magnetic tweezers (MT)-TIRF setups. The pulling module is further characterized in standard flow cells of different thicknesses and glass capillaries, using two types of micrometer size superparamagnetic beads, long DNA molecules, and a home-built device to rotate capillaries with mrad precision. The force range achieved by the magnetic pulling module was between 0.1 and 30 pN. A formalism for estimating forces in flow stretched tethered beads is also proposed, and the results compared with those of lateral MT, demonstrating that lateral MT achieve higher forces with lower dispersion. Finally, we show the compatibility with TIRF microscopy and the parallelization of measurements by characterizing DNA binding by the centromere binding protein ParB from Bacillus subtilis. Simultaneous MT pulling and fluorescence imaging demonstrate the non-specific binding of BsParB on DNA under conditions restrictive to condensation. PMID- 29461551 TI - Aggregation of polyethylene glycol polymers suppresses receptor-mediated endocytosis of PEGylated liposomes. AB - The PEGylated liposome, composed of an aqueous core and a fluid state lipid bilayer shell, is one of the few Food and Drug Administration (FDA) approved drug delivery platforms. To prevent the absorption of serum proteins, the surface of a liposome is decorated by hydrophilic and bio-compatible polyethylene glycol (PEG) polymers, which can significantly extend the blood circulation time of liposomes. In this work, with the help of dissipative particle dynamics (DPD) simulations, we explore how the tethered PEG polymers will affect the membrane wrapping process of PEGylated liposomes during endocytosis. Specifically, we compare the membrane wrapping process of a PEGylated rigid nanoparticle (NP) with a PEGylated liposome under identical conditions. Due to the mobility of grafted PEG polymers on the liposome's surface, the complete wrapping of a PEGylated liposome can be dramatically delayed and blocked, in comparison with a PEGylated rigid NP. For the first time, we observe the aggregation of PEG polymers in the contact region between a PEGylated liposome and the membrane, which in turn leads to a ligand free region on the surface of the liposome during endocytosis. Subsequently, the partially wrapped PEGylated liposome can be bounced back to a less wrapped state. Through free energy analysis, we find that the aggregation of PEG polymers during the membrane wrapping process of a PEGylated liposome introduces a dramatic free energy penalty of about ~800kBT, which is almost twice that of a PEGylated rigid NP. Here kB and T are the Boltzmann constant and temperature, respectively. Such a large energy barrier and the existence of a ligand-free region on the surface of PEGlylated liposomes prevent their membrane wrapping, thereby reducing the chance of internalization by tumor cells. Therefore, our DPD simulation results provide a possible explanation for the inefficient cellular uptake of PEGylated liposomes. In addition, we suggest that by increasing the repulsive interactions between grafted PEG polymers it might be possible to limit their aggregation, and in turn, facilitate the internalization of PEGylated liposomes. The current study provides fundamental insights into the endocytosis of PEGylated liposomes, which could help to design this platform with high efficacy for drug delivery.

AB - Chromatographic methods have become popular in clinical analysis in both routine and research laboratories. The purpose of this review article is to provide an overview of the current state of chromatographic methods, i.e., high-performance liquid chromatography (HPLC), gas chromatography (GC), and supercritical fluid chromatography (SFC), in clinical analysis. The aspects related to method sensitivity, selectivity, analysis time, and throughput have been discussed in detail. Adequate solutions to improve these features have also been presented. HPLC is the most widely used method among the chromatographic methods, whereas GC is dedicated to several specific applications, and SFC is used only marginally certainly due to its only recent comeback to the analytical scene. Based on the literature search, the application fields in clinical analysis are divided into the following groups: drugs, hormones, drugs of abuse, metabolomics, lipidomics, volatile organic compounds, biomarkers and endogenous compounds, proteomics, multi-analyte approches, and others. The important features of these applications have been emphasized. PMID- 29461554 TI - A diarsagermylene and a diarsastannylene stabilised by areneGe/Sn interactions.

AB - Water pollution has become a prominent environmental problem and insoluble oils and soluble dyes are the primary pollution sources. Herein, a facile and environment friendly method is proposed to fabricate robust CuO nanorod-covered meshes for dual-functional water purification. The as-prepared meshes can efficiently eliminate oils in wastewater and in situ photodegrade soluble organic dyes under visible light irradiation. Such a functional mesh is free-standing and recyclable, indicating the outstanding practicability of water sewage disposal.

AB - We present a comprehensive study of the bulk and surface properties of transition metal carbides with rock salt structures and discuss their formation energies and electronic structures.

Specific focus is given to the possible catalytic implications of the surface properties on CO2 hydrogenation. PMID- 29461559 TI - Role of topological scale in the differential fouling of Pseudomonas aeruginosa and Staphylococcus aureus bacterial cells on wrinkled gold-coated polystyrene surfaces. AB - Wrinkled patterns, which possess an extensive surface area over a limited planar space, can provide surface features ranging across the nano- and microscale that have become an engineering material with the flexibility to be tuneable for a number of technologies. Here, we investigate the surface parameters that influence the attachment response of two model bacteria (P. aeruginosa and S. aureus) to wrinkled gold-coated polystyrene surfaces having topologies at the nano- and microscale. Together with flat gold films as the controls, surface feature heights spanned 2 orders of magnitude (15 nm, 200 nm, and 1 micron). The surface wrinkle topology was shown through confocal laser scanning microscopic, atomic force microscopic and scanning electron microscopic image analyses to consist of air-water interfacial areas unavailable for bacterial attachment, which were also shown to be stable by time-lapsed contact angle measurements. Imposition of the nanoscale wrinkles reduced P. aeruginosa attachment to 57% and S. aureus attachment to 20% of their flat equivalent surfaces whereas wrinkles at the microscale further reduced these attachments to 7.5% and 14.5%, respectively. The density of attachments indicated an inherent species specific selectivity that changed with feature dimension, attributable to the scale of the air-water interfaces in contact with the bacterial cell. Parameters influencing static bacterial attachment were the total projected surface areas minus the air-water interface areas and the scale of these respective air-water interfaces (area distribution) with respect to the cell morphology. The range of these controlling parameters may provide new design principles for the evolving suite of physical anti-biofouling materials not reliant on biocidal agents under development. PMID- 29461560 TI - One-pot preparation of polymer microspheres with different porous structures to sequentially release bio-molecules for cutaneous regeneration. AB - Herein, we reveal a double emulsion method combining the sol-gel method to prepare poly(lactic-co-glycolic acid) microspheres with different porous structures for sequential release of two types of biomolecules. By controlling the ripening time of the emulsion, multiple interconnected chambers could be easily chosen to be either embedded in microspheres or opened to the surface. These two types of microspheres exhibited different kinetics for the release of both small molecules and proteins, where the release from microspheres with open pores (5 day over 90%) was much faster than the release from microspheres with embedded pores (25 day over 90%). After loading with interleukin-4 (IL-4) and melatonin, these microspheres were further encapsulated in a sodium alginate hydrogel to form a patch for cutaneous regeneration. The prepared patch was able to recruit alternatively activated (M2) macrophages in the early stage (fast release of IL-4) and promote the growth of blood vessels in the long term (slow release of melatonin), resulting in significantly enhanced cutaneous regeneration. These results also demonstrate the potential of this novel delivery system to deliver multiple therapeutics and achieve synergistic effects. PMID- 29461561 TI - Metastable morphological states of catalytic nanoparticles. AB - During the catalytic synthesis of graphene, nanotubes, fibers, and other nanostructures, many intriguing phenomena occur, such as phase separation, precipitation, and analogs of capillary action. Here, we demonstrate, using in situ, real-time transmission electron microscope imaging and modeling, that the catalytic nanoparticles display functional, metastable states, reminiscent of some protein ensembles in vivo. As a carbon nanostructure grows, the nanoparticle elongates due to an energetically favorable metal-carbon interaction that overrides the surface energy increase of the metal. The formation of subsequent nested tubes, however, drives up the particle's free energy, but the particle remains trapped until an accessible free energy surface allows it to exit the tube. During this time, the nanoparticle continues to catalyze tube growth internally to the nested structure. This universal nonequilibrium thermodynamic cycle of elongation and retraction is heavily influenced by tapering of the structure, which, ultimately, determines the final product and catalyst lifetime. Our results provide a unifying framework to interpret similar phenomena for other catalytic reactions, such as during CO oxidation and boron nitride tube growth, and suggest routes to the practical optimization of such processes. PMID- 29461562 TI - In situ TEM observation of rebonding on fractured silicon carbide. AB - Silicon carbide (SiC) is widely used in harsh environments and under extreme conditions, including at high-power, high-temperature, high-current, high-voltage and high-frequency. The rebonding and self-matching of stack faults (SFs) is highly desirable to avoid catastrophic failure for SiC devices, especially for specific applications in the aerospace and nuclear power industries. In this study, a novel approach was developed using an eyebrow hair to pick up and transfer nanowires (NWs), in order to obtain in situ transmission electron microscope (TEM) images of the rebonding and self-matching of SFs at atomic resolution. During rebonding and healing, the electron beam was shut off. Rebonding on the fractured surfaces of monocrystalline and amorphous SiC NWs was observed by in situ TEM at room temperature. The fracture strength was 1.7 GPa after crack-healing, restoring 12.9% of that of a single crystal NW. Partial recrystallization along the <111> orientation and the self-matching of SFs are responsible for the rebonding of the monocrystalline NW. In comparison, the fracture strengths were 6.7 and 5.5 GPa for the first and second rebonding, respectively recovering 67% and 55% of that of an amorphous NW. Atomic diffusion contributed enormously to the rebonding on fractured surfaces of an amorphous NW, resulting in a healed surface consisting of an amorphous phase and crystallites. This rebonding function provides new insight into the fabrication of high performance SiC devices for the aerospace, optoelectronic and semiconductor industries. PMID- 29461563 TI - External skeletal robusticity of children and adolescents - European references from birth to adulthood and international comparisons. AB - ABSTRACT: Background: In our modern world, the way of life in nutritional and activity behaviour has changed. As a consequence, parallel trends of an epidemic of overweight and a decline in external skeletal robusticity are observed in children and adolescents. Aim: We aim to develop reference centiles for external skeletal robusticity of European girls and boys aged 0 to 18 years using the Frame Index as an indicator and identify population specific age-related patterns. Methods: We analysed cross-sectional & longitudinal data on body height and elbow breadth of boys and girls from Europe (0-18 years, n = 41.679), India (7-18 years, n = 3.297) and South Africa (3-18 years, n = 4.346). As an indicator of external skeletal robusticity Frame Index after Frisancho (1990) was used. We developed centiles for boys and girls using the LMS-method and its extension. Results: Boys have greater external skeletal robusticity than girls. Whereas in girls Frame Index decreases continuously during growth, an increase of Frame Index from 12 to 16 years in European boys can be observed. Indian and South African boys are almost similar in Frame Index to European boys. In girls, the pattern is slightly different. Whereas South African girls are similar to European girls, Indian girls show a lesser external skeletal robusticity. Conclusion: Accurate references for external skeletal robusticity are needed to evaluate if skeletal development is adequate per age. They should be used to monitor effects of changes in way of life and physical activity levels in children and adolescents to avoid negative health outcomes like osteoporosis and arthrosis. PMID- 29461564 TI - Growth prediction of small for gestational age infants within the first weeks after birth. AB - ABSTRACT: Being born small for gestational age (SGA) in length is a sign of growth failure due to malnutrition in pregnancy or other serious disorders. In previous publications it was shown that SGA born neonates may experience a compensatory growth spurt (catch-up growth) in infancy and childhood (Olbertz et al. in press). The timing of this growth spurt, however, was not well described. We analyzed longitudinal data of 5,138 SGA infants and children, collected by licensed physicians in Germany and centrally stored in the Database Management System of CrescNet at the University of Leipzig. We confirm that SGA born infants undergo a catch-up in height SDS after birth and up to 2 years of life. 2,712 SGA newborns out of 2,846 showed catch-up in length SDS. The catch-up occurred already during the 4th to 16th postnatal weeks. We analyzed infants who did not show a catch-up within this time period, or even had a loss in height SDS. These infants have a significant lower height SDS throughout the first 5 years after birth and especially in the timeframe of 60th to 64th month after birth (-1.33 mean height SDS in catch-up group, -2.49 in non-catch-up group, p-value < 0.001, CI = [0.827, 1.483]). Even though the medical reasons for the lack of catch-up growth in young SGA infants may not be known, absence of this catch-up within the 4th to 16th postnatal week can be used to early identify SGA infants with high risk of growth failure within the following 5 years.

AB - Do novel therapies in type 2 diabetes have protective effects on cardiovascular and renal complications? A number of new antidiabetic drug classes have been introduced on the market in the last decade. Regulatory authorities have required that their safety in type 2 diabetes populations with high cardiovascular risk must be assessed. Consequently, a large number of outcome studies have been initiated, several of which have been published in recent years. Overall, this has so far shown that long-acting insulin analogues, DPP4-inhibitors, GLP1 receptor agonists and SGLT2-inhibitors are safe. In addition, a few select agents within the latter two classes have been shown to be superior to placebo with respect to cardiovascular as well as renal outcomes. This review summarizes these recent trials and discusses how the results can be interpreted. It is important to emphasize that the subjects included in these studies had/have high risk for or manifest cardiovascular disease. Therefore, the results cannot be extrapolated to all individuals with type 2 diabetes.

AB - Syphilis - an old imitator is back on the stage Syphilis is one of the oldest sexually transmitted infections and caused by the spirochete Treponema pallidum. The incubation time is 10-90 days and patients are contagious for approximately one year. In Sweden all blood donors and pregnant women are screened. By law, individuals with early syphilis (primary and secondary stages) are reported and contact tracing is performed. The syphilis incidence is increasing in Europe, USA and many other countries. The main drivers are men having sex with men. Diagnosing syphilis can be challenging because the non-tender, often genital ulcer of primary syphilis can go unnoticed. Symptoms during secondary syphilis can be flu-like such as fever, lymphadenopathy and headache; an unspecific skin rash can appear. Serologic tests are usually positive 1-2 weeks after infection. Treatment of choice is benzathinpenicilllin 2.4 million units intramuscularly. Four case reports illustrate the diverse scenario of syphilis infection. PMID- 29461580 TI - Ethnic and cultural aspects of type 2 diabetes AB - Political instability the last decades has forced millions of people to migrate from their homelands. In Sweden today, 1.6 million are born abroad, of which the largest immigrant groups originate from the Middle East. Immigrants from these areas represent high risk populations for type 2 diabetes with prevalence of type 2 diabetes twice as high compared to the native Swedish population. The mechanisms behind this increased diabetes risk are not fully unraveled but are likely connected to lifestyle, socioeconomic situation, genetics and epigenetics. A large proportion still free from diabetes are likely to develop diabetes within the coming decade. To prevent this epidemic, increased awareness of risk factors, lifestyle habits, potential barriers and of success factors for lifestyle change in immigrant populations is important. Examples of such preventive actions are culturally adapted lifestyle interventions addressing cultural barriers and behavioral change, which are described in this article. PMID- 29461581 TI - ?

PMID- 29461585 TI - MicroRNA-125b promotes the regeneration and repair of spinal cord injury through regulation of JAK/STAT pathway. AB - OBJECTIVE: Spinal cord injury (SCI) is a severe trauma to the central nervous system. Long non-coding RNAs have been reported to play essential roles in spinal cord injury. This study mainly explored the role of micro-125 in the regulation of spinal cord injury by regulating STAT3. MATERIALS AND METHODS: The stable mouse model of cervical spinal cord contusion was established by Infinite Horizon spinal cord striker, and the model mice' motor function was analyzed. Bioinformatics databases were used to screen the target mRNAs of micro-125b. qRT PCR was performed to detect the expression of micro-125b and its target genes in injury area of mice' spinal cord. Western Blot and ELISA were introduced to detect the expression of inflammation and apoptosis-related proteins in each group. The recovery status of spinal cord after SCI was assessed by motor function scores and axon counts of mice in each group. RESULTS: Micro-125b appeared to be significantly down-regulated over-time after SCI. JAK1 and STAT1, two important neuregulin proteins, were predicted to be the target genes of micro 125b, and overexpression of micro-125b induced the decrease of phosphorylated JAK1 and STAT1. Enhanced micro-125b expression also allowed axons from the injury area of spinal cord to extend into the outer periphery of the damaged area, thus improving the motor function of the injured rats. Besides, overexpression of micro-125b demonstrated significant neuronal protective effects by reducing apoptosis and inflammatory responses in neurons. CONCLUSIONS: Our data revealed that micro-125b was down-regulated in injured spinal cord, and overexpression of micro-125b promoted the repair and regeneration following spinal cord injury through the regulation of the JAK/STAT pathway. PMID- 29461586 TI - Diffusion weighted imaging (DWI) and apparent diffusion coefficient (ADC) values for detection of malignant vertebral bone marrow lesions. AB - Malignant spinal bone marrow disorders are one of the major causes of significant morbidity and reduction in quality of life in oncological patients. Thus, the characterization of these conditions is of crucial importance in the management of these patients. Magnetic resonance (MR) imaging plays a vital role in differentiation between benign and malignant spinal bone marrow disorders. However, morphological imaging features, based on T1 and T2 relaxation properties, might fail in differentiating between these conditions because signal characteristics may overlap. Quantitative MR imaging based on diffusion weighted imaging (DWI) and apparent diffusion coefficient (ADC) values has been proved to help in defining the nature of the lesion. The aims of this paper were: to review basic principles of DWI technique and ADC maps, to describe DWI and ADC maps appearances of normal vertebral bone marrow briefly, to discuss the DWI and ADC maps characteristics in vertebral malignant lesions, to provide indications for differential diagnosis between malignant and benign lesions. PMID- 29461587 TI - Primary neoplasms of the small bowel at CT: a pictorial essay for the clinician. AB - OBJECTIVE: Primary small intestinal neoplasms are uncommon tumors that are often small and difficult to identify. The aim of this paper is to describe CT technique and features in detecting and characterizing the tumors of the small bowel. MATERIALS AND METHODS: This paper focuses on radiological characteristics of benign and malignant primary neoplasms of the small bowel at CT, with special reference to multidetector-CT techniques, type and modality of administration of contrast agents (by oral route or CT-enterography and by nasojejunal tube or CT enteroclysis). This paper will also provide pictures and description of CT findings of benign and malignant primary neoplasms using examples of CT enterography and CT-enteroclysis. RESULTS: Among CT modalities, CT-enterography has the advantage of defining the real extension of wall lesions, possible transmural extension, the degree of mesenteric involvement and remote metastasis. Other useful modalities for the diagnosis of such lesions like capsule endoscopy and enteroscopy, provide important information but limited to mucosal changes with lower accuracy on extension and bowel wall involvement or submucosal lesions. CONCLUSIONS: Multidetector-CT, performed after distension of the small bowel with oral contrast material and intravenous injection of iodinated contrast material, is a useful method for the diagnosis and staging of small bowel neoplasms. PMID- 29461588 TI - SPOP suppresses osteosarcoma invasion via PI3K/AKT/NF-kappaB signaling pathway. AB - OBJECTIVE: Speckle-type POZ protein (SPOP), is an E3 ubiquitin ligase adaptor that is frequently mutated in prostate and endometrial cancers. SPOP has been shown to be responsible for oncogene SRC-3 ubiquitination and proteolysis in prostate cancers. However, whether SPOP plays a role in osteosarcoma (OS) is unknown. In this study, we investigated the inhibitory effect of SPOP on invasion and migration of OS cells. PATIENTS AND METHODS: Real-time PCR and Western blot were used to detect the expression of SPOP in human OS samples and cell lines. Short hairpin RNA (shRNA) was used to silencing the expression of SPOP. Small scale Real-time PCR screen was used to identify the matrix metalloproteases (MMP) family members responsible for the phenotype caused by SPOP depletion. Matrigel coated invasion chambers were used to detect the invasion ability of SPOP in OS cells. RESULTS: We found that SPOP was down-regulated in clinic OS samples and cultured OS cells. Furthermore, we showed that silencing of SPOP promoted cell migratory and invasive ability of OS cells in vitro, whereas restored the expression of SPOP achieved the opposite effects. At the molecular level, we found that SPOP regulated the activity of "PI3K/Akt/NF-kappaB" signaling pathway in OS cells. CONCLUSIONS: Our results suggested that down-regulation of SPOP promoted OS cells migratory and invasive ability via modulating the "PI3K/Akt/NF kappaB" signaling pathway. Thus, SPOP could be a promising drug target for the treatment of OS invasion. PMID- 29461589 TI - Long non-coding RNA SNHG16 promotes cell growth and metastasis in ovarian cancer. AB - OBJECTIVE: To investigate the expression of long non-coding RNA SNHG16 in ovarian cancer and to further investigate its role in the development of ovarian cancer as well as its potential regulatory mechanism. PATIENTS AND METHODS: Quantitative Real-time polymerase chain reaction (qRT-PCR) was used to detect the expression of SNHG16 in 103 ovarian cancer tissues and normal tissues; the relationship between the expression of SNHG16 and the pathological parameters of ovarian cancer and the prognosis of patients was also analyzed. qRT-PCR was used to further verify the expression of SNHG16 in the ovarian cancer cells. After establishment of SNHG16 knockdown expression model in ovarian cancer cells SKOV-3 and HO8910 using small interfering RNA, the effect of SNHG16 on biological function of ovarian cancer cells was analyzed via cell counting kit-8 (CCK8), transwell invasion and migration assay. Finally, its potential mechanism was analyzed by Western Blot. RESULTS: qRT-PCR results showed that the expression of SNHG16 in ovarian cancer was significantly higher than that in normal tissues, and the difference was statistically significant. Compared with patients with lower expression of SNHG16, patients with higher expression of SNHG16 had higher tumor stage, high rate of distant metastasis and low overall survival rate. Compared with the negative control si-NC group, the cell proliferation, invasion and migration ability in SNHG16 knockdown group (si-SNHG16) significantly decreased. Western Blot showed that after knockdown of SNHG16, expressions of P AKT and MMP9 decreased significantly, while there was no significant change in the total AKT level. CONCLUSIONS: SNHG16 was highly expressed in ovarian cancer, and was correlated with staging, distant metastasis and poor prognosis of ovarian cancer. SNHG16 may activate phosphorylation of AKT and upregulate the expression of MMP9 to promote cell proliferation, invasion and migration of ovarian cancer. PMID- 29461590 TI - Expression and clinical correlation of NGAL and VEGF in endometrial carcinoma. AB - OBJECTIVE: To determine the expression of neutrophil gelatinase-associated lipocalin (NGAL) and vascular endothelial growth factor (VEGF) in endometrial carcinoma. PATIENTS AND METHODS: The clinical features (FIGO staging, pathological type, differentiation level, myometrial invasion depth and tumor size) and immunostaining analysis of endometrial carcinoma (30 cases), atypical hyperplasia (30 cases) and proliferative endometrial tissues (30 cases) were analyzed. Immunohistochemistry and reverse transcription PCR (RT-PCR) were performed to detect the expression of NGAL and VEGF. RESULTS: The positive tissue immunostaining and mRNA expression of NGAL and VEGF in endometrial carcinoma were significantly higher than in either atypical hyperplasia or proliferative endometrial tissues (p<0.05). The relative expression level of NGAL and VEGF was positively correlated with worse FIGO staging, higher differentiation level and a greater myometrial invasion depth (p<0.05); but not with patient age, pathological type or tumor size (p>0.05). CONCLUSIONS: The abnormal high expression of NGAL and VEGF observed in the endometrial carcinoma may be an important biomarker for early tumor diagnosis or as a novel target for therapeutic intervention. PMID- 29461591 TI - Reduced SPOCK1 expression inhibits non-small cell lung cancer cell proliferation and migration through Wnt/beta-catenin signaling. AB - OBJECTIVE: Accumulating evidence suggests that SPARC/osteonectin, cwcv, and kazal like domain proteoglycan 1 (SPOCK1) contributes to the initiation and progression of human cancers. However, little is known about the function mechanisms of SPOCK1 in non-small cell lung cancer (NSCLC). The aim of this study was to investigate the molecular mechanism of SPOCK1 in NSCLC. PATIENTS AND METHODS: The expression levels of SPOCK1 in NSCLC tissues and cell lines were analyzed by qRT PCR and Western blotting. The proliferative activity of NSCLC cells was determined by MTT and colony formation assays. The transwell assay was used to examine the cell migration and invasive ability. To study the impact of SPOCK1 on Wnt/beta-catenin signaling, we further performed Western blotting for related proteins in this pathway. RESULTS: We observed that the expression of SPOCK1 at both protein and mRNA levels was also increased in human NSCLC tissues and cell lines. Functionally, down-regulation of SPOCK1 in NSCLC cells markedly suppressed cell proliferation, colony formation, migration and invasion in vitro. Mechanistically, we found that indicated the activation of Wnt/beta-catenin pathway was suppressed by SPOCK1 silencing. CONCLUSIONS: The expression of SPOCK1 served as a tumor promoter, possibly through the Wnt/beta-catenin signaling pathway in NSCLC. Targeting SPOCK1 could be a potential therapeutic strategy in NSCLC. PMID- 29461592 TI - Health-related quality of life and psychosocial implications in testicular cancer survivors. A literature review. AB - OBJECTIVE: In this review, we focused our attention on Quality of Life (QoL) of testicular cancer survivors (TCSs), in general and in the most relevant areas. Several key findings have been highlighted in our review. MATERIALS AND METHODS: PubMed, MEDLINE and PsycINFO databases were consulted to find published studies, from 1980 to May 2017, that met our inclusion criteria. RESULTS: The majority of studies investigated older adult TCSs, while few studies on adolescent and young adult patients were available. Many studies indicate that health-related QoL (HRQoL) is similar among the TCSs and the general population. Even if QoL deteriorates so clear at the time of diagnosis and throughout treatment, afterward returns to normal levels, as defined by the matched controls. However, there are numerous chronic conditions consequent to diagnosis and treatment of testicular cancer that plague survivors and affect QoL, like Raynaud-like phenomena, peripheral neuropathy, fatigue, anxiety, sexual, fertility and body image problems. Even if these problems can have no effects on the measures of global QoL, they have an impact on the quality of life. Differences between TCSs with and without a partner bring to different outcomes in the adjustments to cancer. CONCLUSIONS: It is necessary to identify TCSs with higher risks of poorer QoL outcomes, to focus interventions on the areas with the greatest impairments. Further researches should consider the effects of testicular cancer on the impaired areas, collecting more data to better identify survivor's needs and consequent interventions, with a special focus on adolescent and young adult TCSs. Other works are requested on therapies, preventive and ameliorative, to reduce chronic side effects of testicular cancer treatment. PMID- 29461593 TI - Expression of miR-205 in renal cell carcinoma and its association with clinicopathological features and prognosis. AB - OBJECTIVE: The aim of the present study was to examine the expression of miR-205 in renal cell carcinoma (RCC) tissue and carcinoma cells; also, we aimed to determine the association of miR-205 expression with the clinicopathological features and prognosis of RCC, and to explore the mechanism of miR-205. PATIENTS AND METHODS: Carcinoma tissue and adjacent normal tissue were collected from 60 patients with RCC, and the expression of miR-205 was determined by semi quantitative PCR, followed by correlation analysis of miR-205 with clinicopathological features and prognosis. Subsequently, the human RCC line, ACHN, was transfected with miR-205, and the effect of miR-205 overexpression on the growth of RCC was examined by MTT assay. Moreover, the effect of miR-205 on the migration of colon cancer cells was studied by transwell assay. Additionally, immunohistochemistry and Western blot were used to investigate the epithelial mesenchymal transition in renal cancer tissue. RESULTS: The expression of miR-205 was downregulated in RCC tissue compared with adjacent non-cancerous tissue (p < 0.01). The expression of miR-205 was closely related to the infiltration and recurrence of tumors (p < 0.01), but was not correlated with a pathological grade or clinical stage (p > 0.05). We also found that overexpression of miR-205 in RCC significantly inhibited the growth of cancer cells (p < 0.01) and significantly reduced the migration ability (p < 0.01). The epithelial-mesenchymal transition occurs in RCC, and miR-205 might inhibit cell proliferation and migration by blocking the epithelial-mesenchymal transition. CONCLUSIONS: The expression of miR-205 is low in RCC, and may play an important role throughout the progression of RCC. Further study of miR-205 may promote the development of a novel therapeutic approach for the treatment of RCC. PMID- 29461594 TI - The impact of NudCD1 on renal carcinoma cell proliferation, migration, and invasion. AB - OBJECTIVE: Renal cell carcinoma (RCC) is the most common malignant tumor in the urogenital system. Its easily metastatic characteristics greatly reduce the postoperative survival rate. NudCD1, as a proto-oncogene, may be involved in the proliferation, migration, and invasion of renal cell carcinoma cell. This study intends to explore the expression of NudCD1 in renal cancer tissue and its effect on renal cell behavior. PATIENTS AND METHODS: NudCD1 expression in RCC tissue was tested Western blot. The cellular localization of NudCD1 was detected by immunohistochemistry (IHC). NudCD1 highly expressed RCC cell line was selected. NudCD1 knockdown or overexpression was performed through cell transfection. Cell proliferation, migration, and invasion were assessed by MTT assay, wound scratch assay, and transwell assay, respectively. RESULTS: NudCD1 mainly located in the cytoplasm and significantly upregulated in RCC tissue compared with adjacent normal control (p < 0.05). NudCD1 expressed highest in A498 cell line among several RCC cell lines. NudCD1 expression was positively correlated with cell proliferation, migration, and invasion in A498. NudCD1 may be treated as a key factor in regulating cell behavior. CONCLUSIONS: NudCD1 significantly increased in RCC and was positively correlated with cell proliferation, migration, and invasion. It could be used as an indicator for the early screening and potential treatment target for RCC. PMID- 29461595 TI - MiR-1271 negatively regulates AKT/MTOR signaling and promotes apoptosis via targeting PDK1 in pancreatic cancer. AB - OBJECTIVE: Pancreatic cancer (PC) possesses a very poor prognosis, and its pathogenesis is not fully understood. Evidence has suggested that microRNAs play important roles in cancer development and progression, the present study was designed to study the function of miR-1271 in PC. PATIENTS AND METHODS: PC tissues and adjacent normal tissues were collected from 17 patients. MiR-1271 and PDK1 expression were quantified by quantitative reverse-transcriptional polymerase chain reaction (RT-PCR). AKT/MTOR signaling activity and PDK1 protein expression were determined by Western blot. Cell viability and apoptosis were assessed by MTT assay and enzyme-linked immunosorbent assay (ELISA). Luciferase assay was used to verify whether miR-1271 directly targets PDK1. RESULTS: MiR 1271 was significantly down-regulated in PC tissues compared with that in the paired normal adjacent tissue, and its expression was up-regulated dose dependently upon cisplatin treatment in PC cells. Overexpression of miR-1271 in these cells produced a pro-apoptotic effect, similar to what caused by cisplatin treatment. Moreover, overexpression of miR-1271 inhibited AKT/MTOR signaling, which was due to the targeting relationship between miR-1271 and PDK1. Finally, knockdown of PDK1 exerted a similar effect on apoptosis to that of miR-1271 overexpression. CONCLUSIONS: MiR-1271 is a potent tumor suppressor in PC, its pro apoptotic function was partially mediated by reduced AKT/MTOR signaling. Targeting miR-1271 may represent an effective strategy for PC treatment. PMID- 29461596 TI - Association of the upregulation of LncRNA00673 with poor prognosis for colorectal cancer. AB - OBJECTIVE: To investigate the effect and clinical significance of long non-coding RNA 00673 (lncRNA00673) in the occurrence and development of colorectal cancer (CRC) through the research on the expression level, biological effect and clinical significance of lncRNA00673 in CRC. PATIENTS AND METHODS: The relative expression of lncRNA00673 in 71 pairs of CRC tissues and cells was detected by quantitative Real-time polymerase chain reaction (qRT-PCR). The correlation of the relative expression of lncRNA00673 with the clinicopathological features of CRC patients was analyzed. The lncRNA00673 interference sequence was designed and synthesized, and its transfection efficiency was detected by qRT-PCR assays. 3 (4,5-Dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide (MTT) assay and clone formation experiments were performed to investigate the effect of lncRNA00673 on the proliferation ability of CRC cells. RESULTS: In CRC tissues of 71 patients, there were 51 patients whose lncRNA00673 level was up-regulated compared with that of cancer-adjacent tissues. The highly expressed lncRNA00673 was positively correlated with tumor, node and metastasis (TNM) staging, regional lymph node metastasis, distant metastasis and tumor size in CRC patients. Cox proportional hazards regression model showed that the highly expressed lncRNA00673 was an independent risk factor for the overall survival of CRC patients. Kaplan-Meier curve analysis showed that highly expressed lncRNA00673 was significantly associated with the relatively lower overall survival (OS). MTT and clone formation experiments showed that knockdown of lncRNA0673 could inhibit the proliferation of CRC cells. CONCLUSIONS: The expression level of lncRNA00673 is up-regulated in CRC tissues and cells, which is related to the degree of malignancy and poor prognosis. LncRNA00673 can be used as a potential molecular marker for the prognosis of CRC. PMID- 29461597 TI - The effect and mechanism of metallothionein MT1M on hepatocellular carcinoma cell. AB - OBJECTIVE: Liver cancer is one of the most common digestive system malignant solid tumors. Its incidence and mortality rates keep high, causing serious mental and economic burden. So far, the exact mechanism of liver cancer onset has not been fully elucidated. Metallothionein (MT) widely exists in various types of organisms with highly conserved structure. It contains the short peptide of cysteine and sulfur protein with high affinity to heavy metals, including cadmium, zinc, and copper. MT1M is an important member of MT family that has been verified to participate in regulating hepatocellular carcinoma, thyroid cancer, cervical cancer, and other tumors. However, MT1M expression and mechanism in hepatoma cells have not been fully elucidated. MATERIALS AND METHODS: Hepatoma cell line HepG2 was divided into control and MT1M group. MT1M plasmid was constructed and transfected to MT1M group. Real-time PCR was used to test MT1M expression. MTT assay was applied to detect HepG2 proliferation. Flow cytometry was performed to determine HepG2 apoptosis. Caspase-3 activity was measured. Western blot was used to detect Bcl-2 and Bax protein levels. RESULTS: MT1M expression significantly increased after MT1M plasmid transfection compared with control (p < 0.05). MT1M group showed inhibited HepG2 proliferation, declined HepG2 apoptosis, enhanced Caspase-3 activity, reduced Bcl-2 protein level, and upregulated Bax protein compared with control (p < 0.05). CONCLUSIONS: MT1M can suppress HepG2 proliferation and induce HepG2 apoptosis through downregulating Bcl-2, upregulating Bax, and enhancing Caspase-3 activity. PMID- 29461598 TI - Association on polymorphisms in LncRNA HOTAIR and susceptibility to HNSCC in Chinese population. AB - OBJECTIVE: More and more evidence has shown that the critical functions of long non-coding RNA (lncRNA) polymorphism in the carcinogenicity mechanism of a variety of cancers. The association between lncRNA HOX transcript antisense intergenic RNA (HOTAIR) polymorphism and the risk of head and neck squamous cell carcinoma (HNSCC) in Chinese population has not been reported. To investigated the effects of HOTAIR polymorphism on cancer susceptibility, the influence of HOTAIR variants on the risk of HNSCC was analyzed in this study. PATIENTS AND METHODS: In this case-control study, the tagging SNPs (rs874945, rs4759314, and rs7958904) in HOTAIR gene were genotyped in Chinese population consisting of 366HNSCC cases and 732 controls. RESULTS: It was found that rs4759314 was associated with a significantly increased risk of HNSCC in Chinese population [GG vs. AA: adjusted odds ratio (OR) = 1.23, 95% confidence interval (CI) = 1.01 1.50; additive model: OR = 1.21, 95%CI = 1.01-1.46]. However, there were no significant associations of rs874945 and rs7958904 with HNSCC risk. CONCLUSIONS: HOTAIR rs4759314 may influence HNSCC susceptibility and serve as a diagnostic biomarker. PMID- 29461599 TI - Microvesicles containing microRNA-21 secreted by proximal tubular epithelial cells are involved in renal interstitial fibrosis by activating AKT pathway. AB - OBJECTIVE: To investigate the role of microvesicles containing microRNA-21 in renal interstitial fibrosis and its possible mechanism. MATERIALS AND METHODS: The renal interstitial fibrosis model was established by unilateral ureteral obstruction, and proximal tubule epithelial cell line (NRK52E) was used for cell model. The phenotype changes of the microvesicles containing microRNA-21 secreted by tubule cells during fibrosis were detected, and possible mechanisms responsible for the process were also analyzed. RESULTS: During the process of renal interstitial fibrosis, microRNA-21 level in the microvesicles secreted by tubule cells was increased. The microRNA-21 released from the damaged renal tubules inhibited the expression of PTEN and activated the AKT-mTOR signaling pathway, thereby exacerbating the renal interstitial fibrosis. CONCLUSIONS: MicroRNA-21 secreted by injured proximal tubule epithelial cells participated in renal interstitial fibrosis by activating the PTEN/AKT signaling pathway. PMID- 29461601 TI - Impact of serum FGF23 levels on blood pressure of patients with chronic kidney disease. AB - OBJECTIVE: To investigate the impact of serum FGF23 levels on blood pressure of patients with chronic kidney disease (CKD). PATIENTS AND METHODS: 128 patients with chronic kidney disease were selected from February 2013 to January 2016. Using CKD staging method, all the patients were divided into 1 to 5 stages according to the glomerular filtration rate. Enzyme-Linked ImmunoSorbent Assay (ELISA) was used to detect serum FGF23 levels of CKD patients and healthy control subjects. 24 h blood pressure monitoring method was used to monitor the mean arterial pressure of patients. Spearman-related analysis method was used to statistically analyze serum FGF23 level, mean arterial pressure and glomerular filtration rate. RESULTS: The serum FGF23 levels of CKD patients were significantly higher than those of the healthy control subjects (p<0.05). Also, FGF23 expression levels in serum were positively correlated with mean arterial pressure based on the results of the Spearman-related analysis. On the other hand, FGF23 expression levels in serum were negatively correlated with glomerular filtration rate. The FGF23 expression levels in serum of the patients were significantly decreased along with the decrease of mean arterial pressure. CONCLUSIONS: Serum FGF23 level is positively correlated with mean arterial pressure and negatively correlated with glomerular filtration rate. So, FGF23 has an important clinical significance that can reflect blood pressure and treatment effect of dialysis of CKD patients. PMID- 29461600 TI - Evaluation of the application of high volume hemofiltration in sepsis combined with acute kidney injury. AB - OBJECTIVE: To investigate the safety and effectiveness of the application of high volume hemofiltration (HVHF) in children with sepsis combined with acute kidney injury. PATIENTS AND METHODS: A total of 76 child patients were enrolled and randomly divided equally (n=38) into control and the observation groups respectively. The control group received conventional volume hemofiltration (the ultrafiltration rate of 35-50 ml/kg/h), and the observation group received HVHF (50-100 ml/kg/h). RESULTS: The serum Interleukin-6 (IL-6), Tumor Necrosis Factor a (TNF-alpha) and creatinine levels were significantly lower in the observation group than the control group at 6 h, 12 h, 24 h and 48 h of hemofiltration (p<0.05). The efficacy rate of treatment was improved. The mortality rate and incidence rate of complications were decreased, and the treatment course was significantly shortened (p<0.05). CONCLUSIONS: The application of HVHF in children with sepsis combined with acute kidney injury has a better safety and effectiveness. PMID- 29461602 TI - Expression of miR-146a-5p in patients with intracranial aneurysms and its association with prognosis. AB - OBJECTIVE: The study aims to detect the association of miR-146a-5p with intracranial aneurysms (IAs). PATIENTS AND METHODS: The expression of miR-146a-5p was compared from plasma samples between 72 patients with intracranial aneurysms (IAs) and 40 healthy volunteers by quantitative Real-time polymerase chain reaction (qRT-PCR). Statistical analysis was performed to analyze the relationship between miR-146a-5p expression and clinical data and overall survival (OS) time of IAs patients. Univariate and multivariate Cox proportional hazards have also been performed. RESULTS: Notably, higher miR-146a-5p expression was found in plasma samples from 72 patients with intracranial aneurysms (IAs) compared with 40 healthy controls. Higher miR-146a-5p expression was significantly associated with rupture and Hunt-Hess level in IAs patients. Kaplan Meier survival analysis verified that higher miR-146a-5p expression predicted a shorter overall survival (OS) compared with lower miR-146a-5p expression in IAs patients. Univariate and multivariate Cox proportional hazards demonstrated that higher miR-146a-5p expression, rupture, and Hunt-Hess were independent risk factors of OS in patients with intracranial aneurysms (IAs). CONCLUSIONS: MiR 146a-5p expression may serve as a biomarker for predicting prognosis in patients with IAs. PMID- 29461603 TI - Correlations of 25(OH)D level with blood lipid, inflammatory factors and vascular endothelial function in diabetic patients. AB - OBJECTIVE: To investigate the correlation between 25-hydroxyvitamin D [25(OH)D] and the lipid profile, inflammatory cytokines, and endothelial function in diabetic patients. PATIENTS AND METHODS: A total of 77 patients with type 2 diabetes mellitus treated in our hospital from January 2015 to March 2017 and 73 healthy volunteers were selected. The 25(OH)D, lipids, inflammatory factors, and endothelial function were compared between the two groups. The levels of 25(OH)D in diabetic patients were also compared to detect the levels of serum lipids and inflammatory cytokines in different groups. According to the inflammatory factors, patients with diabetes mellitus were divided into several groups. In addition, 25(OH)D, endothelial function indicators [nitrogen oxide (NO) and von Willebrand factor (vWF)], serum lipids [triglyceride (TG) and total cholesterol (TC)], high-density lipoprotein (HDL), and inflammatory factor tumor necrosis factor-alpha (TNF-alpha) were compared among different groups. RESULTS: Compared with normal group, the 25(OH)D, NO, and HDL in the diabetic group were significantly lower than those in the normal group (p<0.05). Other lipids and inflammatory factors in the former were significantly higher than those in the normal group. Patients have lower HDL in those with less amount of 25(OH)D. Other blood lipid components such as TC and TG, LDL, and inflammatory factors significantly increased gradually as the 25(OH)D grows (p<0.05). For patients with more inflammatory cytokines, levels of 25(OH)D, NO, vWF, and ET-1 were significantly lower than those with normal inflammatory cytokines. Correlation analysis revealed that 25(OH)D was positively correlated with HDL and NO, but negatively correlated with TG, TC, TNF-alpha, and vWF. CONCLUSIONS: In diabetic patients, the level of 25(OH)D is decreased and the inflammatory factors are increased. In patients with proper supplementation of 25(OH)D, the inflammation can be reduced and endothelial function can be improved. PMID- 29461604 TI - A novel ultrasound-based vascular calcification score (CALCS) to detect subclinical atherosclerosis. AB - OBJECTIVE: To quantify non-coronary vascular calcifications (VC) in asymptomatic patients at low-intermediate cardiovascular risk by a new color Doppler ultrasound (DUS)-based score (the carotid, aortic, lower limbs calcium score, CALCs), and to correlate this score with classical parameters associated with cardiovascular risk [carotid intima media thickness (IMT), and arterial stiffness (AS)]. PATIENTS AND METHODS: All consecutive asymptomatic patients who underwent a screening DUS of non-coronary circulation were evaluated and patients at low intermediate cardiovascular risk were selected according to Framingham risk score (FRS). Among them, we enrolled 70 patients with US evidence of VC and 71 age, sex and FRS matched controls. The presence of VC was correlated with classical markers of cardiovascular risk, such as AS and intima-media thickness (IMT). AS, expressed as pulse wave velocity (PWV) and arterial distensibility, carotid IMT and CALCs were measured for both groups. AS and c-IMT were assessed by a new Radio-Frequency (RF) DUS-based method. CALCs was generated by our previously described B-mode DUS-based method according to number/size of VC in 11 non coronary segments (range 0-33). RESULTS: Patients with VC presented higher AS and IMT values than controls (PWV 8.34+/-0.98 m/s vs. 6.74+/-0.68 m/s, p<0.0001; arterial distensibility 267+/-12 mm vs. 315+/-65 mm, p=0.001; IMT 687+/-132 mm vs. 572+/-91 mm, p<0.0001). Mean CALCs of patients with VC was 8.41+/-7.78. CALCs were significantly correlated with c-IMT (p<0.0001; r=0.3), PWV (p<0.0001; r=0.4) and arterial distensibility (p=0.002; r=-0.1). CONCLUSIONS: DUS-based CALCs is highly correlated with other validated markers of subclinical atherosclerosis, such as c-IMT and AS. Our results demonstrated the ability of CALCs to identify individual predictive factors beyond the traditional risk factors by quantifying an interesting and novel step of the atherogenic process. Future studies on larger series and with adequate follow up are necessary to confirm these results and to evaluate the role of this new marker in monitoring calcific atherosclerosis progression. PMID- 29461605 TI - MiR-210 protects cardiomyocytes from OGD/R injury by inhibiting E2F3. AB - OBJECTIVE: To detect the change in miRNA-210 expression of cardiomyocytes under hypoxia/reoxygenation status. Also, the effect of miR-210 on the apoptosis of cardiomyocytes induced by oxygen-glucose deprivation/reperfusion (OGD/R) and its mechanism through establishing the OGD/R injury model of primary cardiomyocytes in this experiment were investigated. MATERIALS AND METHODS: The cell model of OGD/R injury was established. The cell apoptosis in each group was detected by methyl thiazolyl tetrazolium (MTT) assay and detection of Caspase-3 activity. The change in miR-210 expression in each group was detected by Real-time fluorescence quantitative polymerase chain reaction (PCR). The high-expression and low expression miR-210 models were established through the transient transfection of miR-210 mimic and inhibitor to detect the relevant indexes of cell apoptosis. At the same time, changes in mRNA and protein expressions of E2F3 were detected by RT-PCR and Western blotting, respectively. The E2F3 overexpression vector was constructed, and the overexpression vector plasmid and miR-210 mimic were jointly transfected into the cells to detect the relevant indexes of cell apoptosis. RESULTS: After OGD/R treatment, the activity of Caspase-3 was increased, the survival of cardiomyocytes was significantly inhibited and the expression level of miR-210 was up-regulated in OGD/R injury. Transfection of miR-210 mimic for miR-210 overexpression could alleviate the OGD/R-induced cardiomyocyte injury, while the decrease of miR-210 expression could aggravate the apoptosis of cardiomyocytes. In addition, the high expression of miR-210 could inhibit the protein expression of E2F3, and co-transfection of E2F3 plasmid and miR-210 mimic could reverse the inhibiting effect of miR-210 on the apoptosis of cardiomyocytes. CONCLUSIONS: We confirmed that miR-210 can inhibit the OGD/R induced apoptosis of cardiomyocytes, and miR-210, as an upstream factor, plays a protective role in cardiomyocytes through directly inhibiting the protein expression of its target gene E2F3. PMID- 29461606 TI - Daylight saving time and myocardial infarction: should we be worried? A review of the evidence. AB - Transitions into and out of Daylight Saving Time (DST) may disrupt circadian rhythms and lead to sleep disturbance and deprivation. A first report observed an association between DST and acute myocardial infarction (AMI), especially after the spring shift and in women. We tried to identify and evaluate the possible association between DST and AMI, using the MEDLINE, EMBASE and Google Scholar electronic database (years 2009-2016), with regards to the searching terms 'daylight saving time', 'daylight saving time' plus 'gender', and 'daylight saving time' plus 'acute myocardial infarction'. In total, 72, 10, and 6 studies were found, respectively. Overall, 6 studies, including a total of 87,994 cases, resulted to satisfy the searching request, and were included in the present analysis. All studies confirmed a higher occurrence of AMI in the spring shift, ranging from 4 to 29%, whereas only 1 study showed a higher occurrence of AMI in the autumn shift. By the way, in 5 studies providing separate analysis, the results by sex were not univocal. In fact, as for the spring shift, 2 studies did not show differences between men and women, 2 reported a higher frequency in men, and 1 in women. Regarding the autumn shift, only 1 study reported a higher occurrence of AMI in women. These results support the presence of an association between DST and a modest increase of AMI occurrence, especially for the spring shift, and with no definite gender specific differences. PMID- 29461607 TI - Assessment of atrial fibrillation and ventricular arrhythmia risk in patients with asthma by P wave/corrected QT interval dispersion. AB - OBJECTIVE: Although the relationship between obesity-asthma, obesity-atrial fibrillation (AF) and obesity-sudden cardiac death is clearly known, the risk of AF and ventricular arrhythmia has not been clearly determined in asthmatic patients. The aim of this study was to investigate whether AF, ventricular arrhythmia, and sudden cardiac death risk were increased in asthmatic patients using P wave dispersion (PWD) and corrected QT interval dispersion (CQTD). PATIENTS AND METHODS: The study was designed as a cross-sectional study. A total of 164 participants (88 patients with asthma and 76 healthy volunteers) were enrolled into the study. PWD and CQTD were measured and recorded in both groups. The statistical difference between the two groups was examined. RESULTS: PWD was higher in the asthma patients than in control subjects (31.53 +/- 3.18 vs. 30.33 +/- 3.53, p = 0.023). However, there was no statistically difference between the groups in terms of CQTD measurement (43.9 +/- 1.84 vs. 43.63 +/- 2.06, p = 0.385). In comparison between control group and asthma subgroups (mild, moderate and severe), there was a statistically significant difference among these four groups in terms of PWD (p = 0.017). Subgroup analyses showed that this difference was mainly due to patients with severe asthma. CONCLUSIONS: PWD value was elevated in asthmatic compared to the control group. The CQTD was not statistically significant between the groups. These results indicate that the risk of developing AF in asthmatic patients might be higher than in the normal population. Ventricular arrhythmia and sudden cardiac death risk may not be high in asthmatic patients. PMID- 29461608 TI - High expression of lnc-CRNDE presents as a biomarker for acute myeloid leukemia and promotes the malignant progression in acute myeloid leukemia cell line U937. AB - OBJECTIVE: To detect the expression of long non-coding RNA-CRNDE in patients with acute myeloid leukemia and its effect on proliferation and apoptosis in acute myeloid leukemia cell line U937. PATIENTS AND METHODS: 81 cases of newly diagnosed acute myeloid leukemia (AML) were enrolled, and 35 non-malignant hematological patients were selected as controls. Quantitative RT-PCR (qRT-PCR) was performed to detect the expression of lncRNA-CRNDE in the bone marrow specimens of the subjects, and the difference between the two groups was also compared. The correlation between the expression of lncRNA-CRNDE and the sex, age, classification and total survival of clinical patients was analyzed according to the clinical data. U937 cells and monocytes isolated from normal people were cultured, and the expression of lncRNA-CRNDE in acute myeloid leukemia cell line U937 and normal monocytes was compared. SiRNA-CRNDE and pcDNA CRNDE were transfected into U937 cells, and cell counting kit-8 (CCK-8) assay was performed to detect proliferation of U937 cells, Annexin V/PI flow cytometry was carried out to detect cell apoptosis. Cell cycle was measured by flow cytometry. RESULTS: The expression of lncRNA-CRNDE in patients with AML and U937 cells was significantly higher than that in non-malignant hematological controls. Results of clinical data showed that the expression of lncRNA-CRNDE was associated with the classification and total survival of myeloid leukemia in clinical patients. After transfection of siRNA-CRNDE, the proliferation and cloning ability of U937 cells decreased, while the apoptosis increased (p < 0.01) and cells were arrested in G0-G1 phase. Meanwhile, after transfection of pcDNA-CRNDE, the proliferation ability of U937 cells increased significantly, which indicated that the expression of lncRNA-CRNDE might play an essential role in promoting the proliferation of U937 cells. CONCLUSIONS: LncRNA-CRNDE is highly expressed in the bone marrow tissues of AML patients, and the expression level is negatively correlated with the total survival of those clinical patients. Meanwhile, the expression is higher in FAB type M4 and M5 than that in M1, M2 and M3. LncRNA CRNDE promotes the proliferation and cell cycle of U937 cells, and inhibits cell apoptosis, which is expected to become a molecular marker for predicting and treating AML. PMID- 29461609 TI - The effects of recombinant human growth hormone (rHGH) on survival of slender narrow pedicle flap and expressions of vascular endothelial growth factor (VEGF) and classification determinant 34 (CD34). AB - OBJECTIVE: To explore the effects of recombinant human growth hormone (rHGH) on the survival of the mouse slender narrow pedicle flap and the expressions of vascular endothelial growth factor (VEGF) and classification determinant 34 (CD34). MATERIALS AND METHODS: A total of 20 BALB/c mice were randomly divided into the experimental group (n=10) and control group (n=10). The flaps were transplanted for mice in two groups respectively. 6 h after the operation, the mice in the experimental group were administrated with rHGH via local subcutaneous injection, while the mice in the control group were injected with the same amount of normal saline. The laser Doppler was used to measure the sub flap blood flow rates before the operation, and 3 days, 7 days and 14 days after the operation, respectively; the flap necrosis and survival areas of mice in two groups were measured respectively, and the survival rate of the flap was calculated 14 days after the operation. Afterwards, the flaps of mice in two groups were exfoliated and the shape and structure of flap tissues were tested by the hematoxylin-eosin (HE) staining. Reverse transcription-polymerase chain reaction (RT-PCR) and Western blot were used to test the levels of mRNA and protein of VEGF and CD34 in the flap tissues. RESULTS: The flaps of mice in the control group mainly exhibited the black or grayish-black and lost the elasticity with the hard texture, while those in the experimental group were ruddy in color with favorable elasticity. The survival rate of flaps of mice in the experimental group was significantly higher than that in the control group (83.61 +/- 12.56% vs. 46.25 +/- 9.70%) and the necrosis area of flaps of mice in the experimental group was significantly smaller than that in the control group (1.32 +/- 0.16 vs. 4.13 +/- 0.35, p < 0.05). There were no statistical differences in the blood flow rates of mouse flap both before the operation and three days after the operation between two groups (p > 0.05), while the blood flow rates of mouse flap both 7 days and 3 days after the operation in the experimental group were higher than those in the control group (p > 0.05). Compared with those in the control group, the levels of VEGF and CD34 were significantly increased, but the levels of the inflammatory factors of the interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) were significantly decreased (p < 0.05). CONCLUSIONS: rHGH plays an active role in the survival of the flap through promoting the angiogenesis and inhibiting inflammatory reaction. PMID- 29461610 TI - The effect of DC+CIK combined therapy on rat liver cancer model and its modulatory effect on immune functions. AB - OBJECTIVE: Primary liver cancer is a sort of the most common solid tumors occurred in the digestive system. The incidence and mortality rate maintain at a high level, thus leading to heavy economic and psychological burdens for patients. Next-generation biological therapy, such as cellular immune treatment, improves the medicine efficacy. Cytokine-induced killer (CIK) cells can effectively clear residual tumor lesion and inhibit metastasis or recurrence. Dendritic cells (DCs) can specifically eliminate tumor cells via modulating cellular immune function of the host. This study aimed to investigate the function of DC+CIK combined treatment on rat liver model and its effect on immune functions. MATERIALS AND METHODS: RH-35 tumor cell was used to prepare live cancer model on Wistar rats, which were further divided into control, CIK and DC+CIK groups, in which rats received autograft CIK and DCs. Tumor size was later measured along with liver function index. The secretions of IFN-gamma, IL-4, and TNF-alpha were measured by Real-time PCR and Western blotting. RESULTS: Both CIK and DC+CIK treatment significantly reduced tumor size and improved liver function, increased secretion of IFN-gamma, IL-4, and TNF-alpha, decreased Bcl-2 expression and enhanced Bax expression (p < 0.05 compared to control group). DC+CIK combined therapy presented significantly better efficacy than CIK did. CONCLUSIONS: DC+CIK combined therapy can protect the host against tumors invasion via modulating body immune or liver function, regulating apoptosis/anti-apoptosis balance, which shows better efficacy than CIK alone, and can work as a novel biological therapeutic strategy for liver cancer. PMID- 29461611 TI - Leptin inhibits apoptosis of nucleus pulposus cells via promoting autophagy. AB - OBJECTIVE: To investigate whether leptin can regulate the apoptosis of nucleus pulposus cells by adjusting the autophagy of human degenerative nucleus pulposus cells and its possible molecular mechanism. PATIENTS AND METHODS: The human degenerative nucleus pulposus cells were extracted and cultured, then treated with leptin, leptin inhibitor and leptin neutralizing antibody; the expressions of light chain 3 (LC3) II/I and Beclin-1 were detected by Western blot, and the change of apoptosis rate was detected by flow cytometer. After the nucleus pulposus cells were treated with leptin, bafilomycin A, the autophagy inhibitor, was used to inhibit the autophagy. Western blot was used to detect the expressions of LC3II/I and cleaved caspase 3, and the apoptosis rate was detected by flow cytometer. Finally, Western blot was used to detect the expressions of Akt and extracellular regulated protein kinases 1/2 (Erk1/2) signal pathway associated proteins after nucleus pulposus cells were treated with LY294002, the phosphatidylinositol 3-kinase (PI3K) inhibitor, and PD98059, the extracellular regulated protein kinases (MEK) inhibitor. RESULTS: After the cells were treated with leptin, the expressions of LC3II/I and Beclin-1 could be increased, and the apoptosis rate of nucleus pulposus cells could be decreased (p<0.05). After the degenerative nucleus pulposus cells were treated with leptin inhibitor or neutralizing antibody, the expressions of LC3II/I and Beclin-1 were decreased, and the apoptosis rate of nucleus pulposus cells was increased (p<0.05). Bafilomycin A could increase the expression of LC3II/I (p<0.05), increase the apoptosis rate (p<0.05), and offset the effect of leptin of decreasing the apoptosis rate of nucleus pulposus cells. The results of Western blot showed that LY294002 could inhibit the expression of LC3II/I by inhibiting the Akt phosphorylation (p<0.05), but leptin could partially offset the inhibiting effect of LY294002 on the expression of LC3II/I. PD9805 could partially decrease the expression of LC3II/I via inhibiting the Erk1/2 phosphorylation, but leptin could not reverse the inhibiting effect of PD98059 on the expression of LC3II/I. CONCLUSIONS: Leptin inhibits the apoptosis of degenerative nucleus pulposus cells via promoting autophagy, and leptin regulates the autophagy of human degenerative nucleus pulposus cells through the phosphorylated Erk1/2 signal. PMID- 29461612 TI - The hyperthermic intraoperative intraperitoneal chemotherapy in the treatment of advanced abdominopelvic cancer. Personal experience on 103 procedures during a seventeen year period in a single Italian center. AB - OBJECTIVE: Integration of different therapeutic strategies in cancer surgery in the last years has led from treating primary lesions to the surgical treatment of metastases. The purpose of this paper is to report a single Italian center experience of treatment of peritoneal carcinosis of the abdominopelvic malignancies. PATIENTS AND METHODS: 103 HIPEC procedures were performed in 17 years on 94 selected patients affected by abdominopelvic cancer. The PCI score was calculated at laparotomy. The CC score was calculated before doing HIPEC. HIPEC was carried out according to the Coliseum technique. RESULTS: The surgical cytoreduction allowed 89 patients to be subjected to HIPEC treatment with a CC score 0; 9 patients with a CC 1; 3 patients with a CC 2 and 2 patients with a CC 3. In 22 patients postoperative complications were recorded. No operative mortality occurred. The median follow-up of 53 months shows a rate of survival equivalent to 49 %, with a relapse in 46 patients, 29 of them reached exitus. CONCLUSIONS: The surgical resection alone for patients affected by advanced cancer with peritoneal carcinomatosis cannot be considered a sufficient treatment any longer and HIPEC would help to prolong survival in these patients. PMID- 29461613 TI - Paraquat promotes the epithelial-mesenchymal transition in alveolar epithelial cells through regulating the Wnt/beta-catenin signal pathway. AB - OBJECTIVE: To investigate whether paraquat (PQ)-induced rat alveolar type II cells (RLE-6TN) epithelial-mesenchymal transition (EMT) and to explore the underlying molecular mechanism. MATERIALS AND METHODS: In the present study, RLE 6TN cells were treated by 20 MUmol/L PQ, and then the morphology was observed under an inverted microscope; RT-PCR and Western blot were performed to detect the expression level of EMT related markers, E-cadherin, and vimentin, as well as Wnt/beta-catenin signaling pathway. In addition, we performed the transwell invasion assay to detect the ability of cell invasion. RESULTS: We demonstrated that PQ was able to induce the transition of RLE-6TN cells from epithelial morphology to fibroblast-like morphology, associated with the acquisition of migratory properties. Phenotypically, PQ induced-EMT was characterized by loss of epithelial cell markers including E-cadherin, while upregulation of mesenchymal cell markers including vimentin, was concurrent with the activation of Wnt/beta catenin signaling pathway. Furthermore, knockdown of beta-catenin by using specific siRNA could reverse PQ triggered EMT process and attenuated cell migration ability. CONCLUSIONS: PQ promotes RLE-6TN epithelial-mesenchymal transition by upregulating the expression of Wnt/beta-catenin. PMID- 29461614 TI - Mitochondria-mediated disturbance of fatty acid metabolism in proximal tubule epithelial cells leads to renal interstitial fibrosis. AB - OBJECTIVE: To investigate the role of mitochondria-mediated fatty acid metabolism in proximal tubule cells in renal interstitial fibrosis. MATERIALS AND METHODS: Intraperitoneal injection of folate was performed to induce renal interstitial fibrosis in mice. Polymerase chain reaction (PCR) was used to detect the expression of cytochrome c oxidase subunit IV (COX4IL) and phosphoenolpyruvate carboxykinase 1 (PCK1) in samples. Electron microscope was used to detect the activity of mitochondria. Serum creatinine and urea nitrogen were chosen as evaluation criteria for renal function. Western-blotting was used to detect protein expression of cells. Immunohistochemistry was used to test renal structure and deposition of collagen. RESULTS: In renal interstitial fibrosis, mitochondria mediated the dysfunction and the promotion of tubulointerstitial fatty acid metabolism. Besides, it could also reduce renal interstitial fibrosis and alleviate the fatty acid metabolism of tubulointerstitial fibrosis. CONCLUSIONS: Mitochondrial dysfunction induced fatty acid metabolism is an important factor to promote the progress of renal interstitial fibrosis. Intervention of related targets of fatty acid metabolism is expected to become a new treatment for renal interstitial fibrosis. PMID- 29461615 TI - Bilastine safety in drivers who need antihistamines: new evidence from high-speed simulator driving test on allergic patients. AB - OBJECTIVE: Bilastine is a highly selective, non-sedating antihistamine, indicated for the symptomatic treatment of allergic rhinoconjunctivitis and urticaria. Available data suggest that bilastine interferes neither with driving ability nor with flying-related performance. However, no data are available on the effect of bilastine on the driving ability in extreme conditions. Here we analyzed the effect of 7 days treatment with 20 mg bilastine in patients with allergic rhinitis and/or chronic urticaria, on psychophysical performance assessed by the Formula One (F1) high-speed simulator-driving test. PATIENTS AND METHODS: This study is a phase IV, interventional, prospective, mono-centric, single arm, open label trial. Eighteen outpatients affected by allergic rhinitis and/or chronic urticaria, able to perform a preliminary driving test on F1 simulator were considered (V-1). First, the patients had a screening visit to assess their eligibility (V0). Visit 1 (V1), at the end of placebo before bilastine treatment and Visit 2 (V2), at the end of bilastine treatment. The primary variable parameter was the ability to maintain the vehicle in a central position at different speeds (50, 150, and 250 km/h). RESULTS: Bilastine had a good safety profile and was well tolerated in terms of adverse events, laboratory parameters and vital signs. Bilastine did not have any negative effect on the ability to maintain the requested path, a constant speed as well as on attention and reactivity levels, even in extreme driving conditions. CONCLUSIONS: This study is the first done in patients with allergic rhinitis and/or chronic urticaria using a F1-high speed simulator-driving test evaluating subjects' performance under bilastine treatment. PMID- 29461616 TI - Leukotriene receptor antagonists do not improve lung function decline in COPD: a meta-analysis. AB - OBJECTIVE: Leukotriene receptor antagonists (LTRA), the anti-inflammatory agents, have been reported new therapeutic value in chronic obstructive pulmonary disease (COPD). However, the effects of LTRA on lung function decline in COPD were determined with inconsistent results and a meta-analysis is needed. MATERIALS AND METHODS: Published cohort or randomized controlled studies were retrieved from PubMed and Embase databases. RESULTS: Pooled standardized mean difference (SMD) with 95% confidence interval (CI) was calculated in a random effects model. Six studies involving 221 COPD patients were included. Pooled effect size showed no significant improvements in FEV1 (SMD: 0.28, 95% CI: -0.17 to 0.72, p=0.227), FVC (SMD: 0.54, 95% CI: -0.10 to 1.18, p=0.597) and FEV1/FVC (SMD: 0.18, 95% CI: 0.09 to 0.46, p=0.189) in COPD patients after LTRA treatment. In subgroup analysis, neither short-term (<1 year) (SMD: 0.47, 95% CI: -0.06 to 0.99, p=0.082) nor long-term (>=1 year) (SMD: -0.13, 95% CI: -0.57 to 0.31, p=0.561) LTRA exposure could benefit lung function decline in COPD. CONCLUSIONS: This meta analysis suggests neither short-term nor long-term exposure of LTRA can improve lung function decline in COPD. However, large scale randomized controlled trials are urgently warranted. PMID- 29461617 TI - JAK/STAT5 signaling pathway inhibitor ruxolitinib reduces airway inflammation of neutrophilic asthma in mice model. AB - OBJECTIVE: The aim of this study was to explore the role of JAK/STAT signaling pathway inhibitor Ruxolitinib in neutrophilic airway inflammation and its possible immunological mechanism. MATERIALS AND METHODS: A total of 60 female C57BL/6 mice were randomly divided into neutrophilic asthma (NA) group, Ruxolitinib-treated (Ruxo) group and control (Con) group. Mice in NA and Ruxo groups were sensitized with ovalbumin (OVA) and excited to establish mice models of asthma. Bronchoalveolar lavage fluid (BALF) was collected at 24 h after the last atomization, and the total number of karyocyte and the percentages of sorted cells were detected. The activity of interleukin-17 (IL-17) in BALF was detected by enzyme-linked immunosorbent assay (ELISA). Lung tissue was separated and subjected to hematoxylin-eosin (HE) staining, and the pathological changes of lung tissue were observed under an optical microscope. The proportion of T helper 17 (Th17) cells in the lung was detected by flow cytometry (FCM). After successful modeling of NA mice, immunomagnetic bead purified mouse splenic cluster of differentiation 4+(CD4+) T was treated with IL-7 and Ruxolitinib, and the proportion of differentiated Th17 cells to CD4+ T cells and Ki-67, B-cell lymphoma 2 (Bcl-2) and activated Caspase3 expressions in Th17 cells were detected via FCM. RESULTS: Compared with those in NA group, the number of karyocytes and the percentages of neutrophils (NEU) and eosinophils (EOS) in BALF in Ruxo group were significantly reduced. The pathological changes of lung tissue in Ruxo group were overtly less than those in NA group. In comparison with NA group, Ruxo group had decreased IL-17A level in BALF and reduced proportion of Th17 cells in lung tissue. In in vitro experiment, compared with those in Con group, decreased percentages of Ki-67 and Bcl-2 proteins and increased percentage of Caspase3 in Th17 cells were found in Ruxo group. CONCLUSIONS: Ruxolitinib may suppress the survival of Th17 cells by inhibiting the JAK/STAT5 signaling pathway and regulate the anti-apoptosis proteins Bcl-2 and Caspase3, thus promoting the increase of Thl7 cells entering the apoptotic pathway and reducing airway inflammation in NA mice. PMID- 29461618 TI - TMS as tool to investigate the effect of pharmacological medications on cortical plasticity. AB - The application of medications with a well-defined mode of action on a neurotransmitter or neuromodulator of the central nervous system (CNS) can be utilized to test the pharmaco-physiological properties of transcranial magnetic stimulation (TMS) on cortical excitability and plasticity. Similarly, a physiologically well-defined TMS measure of cortical excitability may be exploited to study a particular drug's effect at the level of the cerebrum. In this review, we aim to assess the impact of calcium channel blockers, Selective Serotonin Reuptake Inhibitors (SSRIs), and GABAergic agents on cortical excitability and plasticity while concurrently investigating how TMS can enhance this understanding. We will begin by reviewing the basics of neuroplasticity, as explored in animal experimentation, and relate this to our knowledge about neuroplasticity induced in humans by TMS techniques. We will then discuss pharmacological modulation of plasticity in humans. Finally, we will review abnormalities of plasticity inherent to certain neuropsychiatric diseases and discuss how the combination of TMS with pharmacological intervention can augment our knowledge of the pathophysiology of these diseases and guide purposeful treatment. PMID- 29461619 TI - MicroRNA-200c suppressed cervical cancer cell metastasis and growth via targeting MAP4K4. AB - OBJECTIVE: To dissect the functioning mode of miR-200c on cervical cancer cell metastasis and growth and provide therapeutic targets for cervical cancer. PATIENTS AND METHODS: By quantitative Real-time polymerase chain reaction, the miR-200c expression level in 42 pairs of cervical cancer tissue samples and six cervical cancer-derived cell lines were examined. Using miR-200c mimics, we analyzed the effects of miR-200c over-expression on cell proliferation, invasion, and migration. Dual-luciferase activity assay was recruited to examine the potential target gene MAP4K4 that predicted by several databases. Protein level was studied using Western blot. RESULTS: miR-200c expressed significantly lower in cervical cancer tissue samples and cell lines. And over-expression of miR-200c in cervical cancer cells significantly decreased the cell invasion, migration and proliferation abilities. Dual-luciferase and Western blot confirmed MAP4K4 as a target gene of miR-200c. Furthermore, up-regulation of MAP4K4 counteracted the suppressive effect of miR-200c over-expression on cell growth and metastasis. CONCLUSIONS: miR-200c could suppress cervical cancer cell proliferation and progression via regulating MAP4K4, which might provide a new target for cervical cancer diagnosis and therapy. PMID- 29461620 TI - Developing a Core Outcome Set for Trials to Improve Medication Use: Guidelines or Guidance? PMID- 29461621 TI - Core Outcome Set for Trials Aimed at Improving the Appropriateness of Polypharmacy in Older People in Primary Care. AB - OBJECTIVES: To develop a core outcome set (COS) for use in effectiveness trials of interventions aiming to improve the appropriateness of polypharmacy in older people in primary care. DESIGN: Standard COS development methodology was followed, comprising identification of outcomes of studies from an update of a Cochrane systematic review and previously collected qualitative data and an online Delphi consensus exercise involving three rounds. PARTICIPANTS: An international panel of 160 stakeholders comprising 120 healthcare experts and a public participant panel of 40 older people. MEASUREMENTS: Outcomes identified from studies included in the Cochrane review and secondary analysis of previously collected qualitative data were scored on a 9-point Likert scale using the GRADE scoring system anchored at 1 (not important) and 9 (critical). Consensus criteria for the COS were defined as 70% or more of participants scoring the outcome as critical and 15% or fewer scoring the outcome as not important. RESULTS: Twenty nine outcomes identified from the Cochrane review and existing qualitative data were included in the Delphi exercise. The final COS comprised 16 outcomes. The 7 highest-ranked outcomes were serious adverse drug reactions, medication appropriateness, falls, medication regimen complexity, quality of life, mortality, and medication side effects. CONCLUSION: A COS for interventions aiming to improve the appropriateness of polypharmacy for older people in primary care has been developed. Future work will focus on identifying appropriate tools to measure. PMID- 29461622 TI - Fidelity of motivational interviewing in an American Indian oral health intervention. AB - OBJECTIVES: Assess fidelity of a motivational interviewing (MI) intervention focused on preventing early childhood caries in a cohort of American Indian mothers with newborns. METHODS: Four interventionists were trained to administer an oral health MI intervention. The MI sessions were audio recorded to enable scoring as part of fidelity studies to assess the interventionist's degree of competence in using MI principles. Evaluation of the interventionists was completed using the Motivational Interviewing Treatment Integrity (MITI) 3.1.1. which assesses global ratings and behaviour counts. Two reviewers evaluated and scored the MI sessions; a random sample of twenty per cent of the total interviews was scored by a trained reviewer and fifty per cent of the randomly selected files scored by an external expert. A total of 225 files were coded by the trained reviewer and 121 files by the external expert. RESULTS: Mean global scores for all interventionists combined were around 4.0 (expert competence). Scores for reflection to question ratios (around 0.6) were below beginner competence. Scores ranged from beginner to expert competence for open-ended questions (54%-56%), complex reflections (38%-43%) and MI-adherent statements (93%-95%). There was variation in competence for the four interventionists when analysed individually. Inter-rater reliability scores for the two reviewers ranged from fair (0.40-0.59) to good (0.60-0.74). The MI interventionist rated the best in the fidelity assessment had the worst study outcomes compared to other interventionists. CONCLUSIONS: Individual interventionists' scores for the MITI global ratings and behaviour counts reflected variation in competence and ranged from below beginner to expert levels. A higher competence level of the interventionist as assessed by the fidelity study was not related to better study outcomes.

AB - Homogentisic acid (HGA) is a diagnostic metabolite that accumulates in the urine and tissues of patients with alkaptonuria which is a rare autosomal recessive disease. HGA is a specific metabolite in urine and serum, which is used for diagnosis of alkaptonuria. This study presents an inexpensive and easy capillary electrophoretic method for the quantitative determination of HGA in urine samples. The method was optimized using full factorial experimental design. The optimal separation electrolyte and separation voltage were revealed as 45 mmol/L phosphate buffer at pH 7.0 and 22 kV, respectively. Under these conditions the presence of HGA was detected in 6 min. Repeatability of migration times and corrected peak areas of HGA (as RSD) were 0.37 and 1.99, respectively. The detection limit was 0.56 MUg/mL, 3 times of the average noise, and the quantification limit was 1.85 MUg/mL, 10 times the average noise for HGA. Urine samples were directly injected to the capillary without any pretreatment step. PMID- 29461624 TI - The Walking Corpse Syndrome: Geriatrics and the Electronic Health Record.

AB - The high prevalence of oral diseases and the persistent nature of socioeconomic inequalities in oral health outcomes across societies presents a significant challenge for public health globally. A debate exists in epidemiology on the merits of investigating population variations in health and its determinants over studying individual health and its individual risk factors. The choice of analytical unit for health outcomes at the population level has policy implications and consequences for the causal understanding of population-level variations in health/disease. There is a lack of discussion in oral epidemiology on the relevance of studying population variations in oral health. Evidence on the role of societal factors in shaping variations in oral health at both the individual level and the population level is also mounting. Multilevel studies are increasingly applied in social epidemiology to address hypotheses generated at different levels of social organization, but the opportunities offered by multilevel approaches are less applied for studying determinants of oral health at the societal level. Multilevel studies are complex as they aim to examine hypotheses generated at multiple levels of social organization and require attention to a range of theoretical and methodological aspects from the stage of design to analysis and interpretation. This discussion study aimed to highlight the value in studying population variations in oral health. It discusses the opportunities provided by multilevel approaches to study societal determinants of oral health. Finally, it reviews the key methodological aspects related to operationalizing multilevel studies of societal determinants of oral health.

AB - Growing evidence provides new insights about myasthenia gravis (MG) with antibodies against muscle-specific tyrosine kinase (MuSK-MG), including its pathogenesis, clinical and electrophysiological manifestations, and treatment. Data now support the presence of both presynaptic and postsynaptic dysfunction in MuSK-MG. This is 1 of many key differences between MuSK-MG and acetylcholine receptor antibody-MG (AChR-MG), especially as it pertains to potential therapeutic implications. In comparison to AChR-MG, MuSK-MG is generally more refractory to treatment. However, because MuSK-MG is better understood and more readily recognized today, there are more reports of a relatively benign course. The most effective immunotherapies for MuSK-MG are corticosteroids, plasmapheresis, and rituximab. With appropriate therapy, most patients with MuSK MG achieve minimal manifestation status or better on the postintervention status outlined by the Myasthenia Gravis Foundation of America. A minority of patients remain refractory to treatment, and optimal management for this group remains a considerable challenge. Muscle Nerve 58: 344-358, 2018. PMID- 29461625 TI - Beyond symptomatic relief for chemotherapy-induced peripheral neuropathy: Targeting the source. AB - Chemotherapy-induced peripheral neuropathy (CIPN) is a serious adverse side effect of many chemotherapeutic agents, affecting >60% of patients with cancer. Moreover, CIPN persists long into survivorship in approximately 20% to 30% of these patients. To the authors' knowledge, no drugs have been approved to date by the US Food and Drug Administration to effectively manage chemotherapy-induced neuropathic pain. The majority of the drugs tested for the management of CIPN aim at symptom relief, including pain and paresthesia, yet are not very efficacious. The authors propose that there is a need to acquire a more thorough understanding of the etiology of CIPN so that effective, mechanism-based, disease-modifying interventions can be developed. It is important to note that such interventions should not interfere with the antitumor effects of chemotherapy. Mitochondria are rod-shaped cellular organelles that represent the powerhouses of the cell, in that they convert oxygen and nutrients into the cellular energy "currency" adenosine triphosphate. In addition, mitochondria regulate cell death. Neuronal mitochondrial dysfunction and the associated nitro-oxidative stress represent crucial final common pathways of CIPN. Herein, the authors discuss the potential to prevent or reverse CIPN by protecting mitochondria and/or inhibiting nitro oxidative stress with novel potential drugs, including the mitochondrial protectant pifithrin-MU, histone deacetylase 6 inhibitors, metformin, antioxidants, peroxynitrite decomposition catalysts, and anti-inflammatory mediators including interleukin 10. This review hopefully will contribute toward bridging the gap between preclinical research and the development of realistic novel therapeutic strategies to prevent or reverse the devastating neurotoxic effects of chemotherapy on the (peripheral) nervous system.

AB - Sorgoleone, a major component of the hydrophobic root exudates of Sorghum spp., is probably responsible for many of the allelopathic properties attributed to members of this genus. Much of the biosynthetic pathway for this compound has been elucidated, with the exception of the enzyme responsible for the catalysis of the addition of two hydroxyl groups to the resorcinol ring. A library prepared from isolated Sorghum bicolor root hair cells was first mined for P450-like sequences, which were then analyzed by quantitative reverse transcription polymerase chain reaction (RT-qPCR) to identify those preferentially expressed in root hairs. Full-length open reading frames for each candidate were generated, and then analyzed biochemically using both a yeast expression system and transient expression in Nicotiana benthamiana leaves. RNA interference (RNAi) mediated repression in transgenic S. bicolor was used to confirm the roles of these candidates in the biosynthesis of sorgoleone in planta. A P450 enzyme, designated CYP71AM1, was found to be capable of catalyzing the formation of dihydrosorgoleone using 5-pentadecatrienyl resorcinol-3-methyl ether as substrate, as determined by gas chromatography-mass spectroscopy (GC-MS). RNAi mediated repression of CYP71AM1 in S. bicolor resulted in decreased sorgoleone contents in multiple independent transformant events. Our results strongly suggest that CYP71AM1 participates in the biosynthetic pathway of the allelochemical sorgoleone. PMID- 29461629 TI - Development and validation of a LC-MS/MS method for quantitation of fosfomycin - Application to in vitro antimicrobial resistance study using hollow-fiber infection model. AB - Extensive use and misuse of antibiotics over the past 50 years has contributed to the emergence and spread of antibiotic-resistant bacterial strains, rendering them as a global health concern. To address this issue, a dynamic in vitro hollow fiber system, which mimics the in vivo environment more closely than the static model, was used to study the emergence of bacterial resistance of Escherichia coli against fosfomycin (FOS). To aid in this endeavor we developed and validated a liquid chromatography-tandem mass spectrometry (LC-MS/MS) assay for quantitative analysis of FOS in lysogeny broth. FOS was resolved on a Kinetex HILIC (2.1 * 50 mm, 2.6 MUm) column with 2 mm ammonium acetate (pH 4.76) and acetonitrile as mobile phase within 3 min. Multiple reaction monitoring was used to acquire data on a triple quadrupole mass spectrometer. The assay was linear from 1 to 1000 MUg/mL. Inter- and intra-assay precision and accuracy were <15% and between +/-85 and 115% respectively. No significant matrix effect was observed when corrected with the internal standard. FOS was stable for up to 24 h at room temperature, up to three freeze-thaw cycles and up to 24 h when stored at 4 degrees C in the autosampler. In vitro experimental data were similar to the simulated plasma pharmacokinetic data, further confirming the appropriateness of the experimental design to quantitate antibiotics and study occurrence of antimicrobial resistance in real time. The validated LC-MS/MS assays for quantitative determination of FOS in lysogeny broth will help antimicrobial drug resistance studies.

AB - OBJECTIVES: To investigate factors associated with lower likelihood of discharge to home from geriatric intermediate care facilities in Japan. DESIGN: Retrospective cohort study. SETTING: We used data from the nationwide long-term care (LTC) insurance claims database (April 2012-March 2014). PARTICIPANTS: Study participants were 342,758 individuals newly admitted to 3,459 geriatric intermediate care facilities during the study period. MEASUREMENTS: The primary outcome was discharge to home. We performed a multivariable competing-risk Cox regression with adjustment for resident-, facility-, and region-level characteristics. Resident level of care needs and several medical conditions were included as time-varying covariates. Death, admission to a hospital, and admission to another LTC facility were treated as competing risks. RESULTS: During the 2-year follow-up period, 19% of participants were discharged to home. In the multivariable competing-risk Cox regression, the following factors were significantly associated with lower likelihood of discharge to home: older age, higher level of care need, having several medical conditions, private ownership of the facility, more beds in the facility, and more LTC facility beds per 1,000 adults aged 65 and older in the region. CONCLUSION: Only 19% of residents were discharged to home. Our results are useful for policy-makers to promote discharge to home of older adults in geriatric intermediate care facilities.

AB - BACKGROUND: Higher all-cause mortality in asthmatics has been shown previously. Polysensitization is associated with higher morbidity among asthmatic children, and allergic rhinitis and/or allergic conjunctivitis (AR/AC) are associated with higher morbidity in adult asthmatics. Little is known about the effect of AR/AC and other factors on mortality among adult asthmatics. The aim was to study mortality and its risk factors in adults with and without asthma. METHODS: We randomly selected 1648 asthmatics with age over 30 years from national registers and matched the asthma sample with one or two controls. Baseline information was obtained by a questionnaire in 1997, and the study population was linked with the death certificate information of Statistics Finland from 1997 to 2013. Overall and cause-specific survival between the groups was compared in several adjusted models. RESULTS: During a mean follow-up period of 15.6 years, 221 deaths among 1052 asthma patients and 335 deaths among 1889 nonasthmatics were observed. Cardiovascular diseases were the main cause of death in both groups. Asthma was associated with increased all-cause mortality (adjusted HR 1.25; 95% CI 1.05 1.49, P = .011) as well as mortality from chronic obstructive pulmonary disease (HR 12.0, 4.18-34.2, P < .001) and malignant neoplasms of respiratory organs (HR 2.33, 1.25-4.42, P = .008). Among asthmatics, smoking was associated with increased all-cause mortality, and self-reported AR/AC was associated with decreased mortality. Among nonasthmatics, smoking, and obesity were associated with increased all-cause mortality, whereas female gender showed an association with a decreased risk. CONCLUSIONS: Increased mortality among adult asthmatics was largely explained by the development of COPD, malignant respiratory tract neoplasms, and cardiovascular diseases. Smoking cessation is important for reduction in total mortality in both asthmatic and nonasthmatic adults. AR/AC was associated with decreased mortality only in asthmatics. Thus, studies in other populations of larger size are needed to explore further the nature of this association. PMID- 29461633 TI - Neuromuscular dysfunction in the cancer patient: Evaluation and treatment. AB - Cancer is a common diagnosis. In conjunction with various anti-neoplastic therapies delivered sequentially or concurrently, it makes oncology patients among the most complex to treat. This review uses a series of case studies to discuss the diagnosis and treatment of cancer-related nerve and muscle disorders. Oncologic treatment interventions such as surgery, chemotherapy, radiation therapy, and hormonal therapy, often have predictable side-effects, and sometimes their associated disability can be mitigated, especially if recognized early. Disease progression can mimic other diagnoses. The case studies provide a lens through which to study the presenting symptoms, differential diagnoses, diagnostic evaluation, and treatment interventions. These are all considered within the context of the patient's prognosis and health-related quality of life. Muscle Nerve 58: 335-343, 2018. PMID- 29461634 TI - Feasibility study of sucrose and fat replacement using inulin and rebaudioside A in cake formulations. AB - : Cake is a popular food around the world, however, it is considered as unhealthy due to its high fat and sucrose content. To satisfy customers' demand for a low fat and sucrose cake, in this research both sucrose and fat content of the cake were reduced by using rebaudioside A (Reb A; as a natural sucrose replacer) and inulin (as a natural fat replacer) at 0%, 25%, 50%, 75%, and 100%. The water content of different formulation was adjusted to obtain a constant batter viscosity similar to the control (3,757 cP). By reducing sucrose and fat content up to 50%, water activity increased and the cakes became more asymmetrical. However, other physical properties including baking weight loss, height, volume, crust color, and texture were similar to those of the control. Higher levels of replacement (75% and 100%) resulted in remarkable loss of different quality attributes. These samples showed higher water activity and baking loss, lower volume, harder texture, darker color, and highly asymmetrical shape. Thus, successful reduction of both fat and sucrose in cakes is possible by using inulin and Reb A at replacement levels no more than 50%. PRACTICAL APPLICATIONS: Customers' demand for healthy and yet tasty and high-quality foods is increasing around the world. Therefore, finding applicable and safe methods to produce such products is of great interest in the food manufacturing to satisfy customers. Health conscious customers avoid consumption of cakes because it contains high sucrose and fat content. Many studies have been performed to reduce either fat or sucrose content, while a few studies are available to show the reduction of both fat and sucrose in the same product. This study indicates the results of an applicable method to reduce fat and sucrose content of cakes simultaneously. Using rebaudioside A (as a natural sucrose replacer) and inulin (as a natural fat replacer) up to 50% of sucrose and fat content of cakes were reduced and the resulting cake had very similar physical properties to the control. PMID- 29461636 TI - Dental knowledge and dental service utilization: A 2-year follow-up study. AB - OBJECTIVES: To investigate associations of dental knowledge with dental service utilization over 2 years in South Australians aged 45-54 years. METHODS: In 2004 2005, a random sample of 2469 adults aged 45-54 years from Adelaide, South Australia, who were selected from the Australian electoral roll was surveyed. The outcome variables were the numbers of visits and dental services received over 2 years. Data were analysed using log-binomial and Poisson regression. Statistical significance was determined at P < .05. RESULTS: The response rates were 43.8% in the study group (n = 879) and 50.7% in the comparison group (n = 107). Oral examinations were conducted on 709 persons (81% of study group participants). Dental services data were collected from approximately 60% of participants at the end of years 1 and 2. After adjusting for sex, education, health card status, toothbrushing and inadequate dentition, higher caries knowledge and periodontal knowledge scores were associated with higher percentages of persons making dental visits (prevalence ratio, 95% CI: 1.2, 1.1-1.3 and 1.1, 1.0-1.3), and lower rates of extraction (rate ratio, 95% CI: 0.2, 0.1-0.4 and 0.4, 0.3-0.7) and endodontic services (0.5, 0.3-0.9 and 0.5, 0.3-0.7). Higher caries knowledge was associated with lower rates of fillings (0.8, 0.7-0.9) and denture services (0.1, 0.0-0.6), while higher periodontal knowledge was associated with higher numbers of visits (1.3, 1.2-1.5), and prophylaxis services (1.4, 1.1-1.8) and crowns (1.7, 1.1 2.5). CONCLUSION: South Australians aged 45-54 years with higher dental knowledge had lower rates of invasive treatment over 2 years. These findings warrant policy initiatives that highlight the importance of dental knowledge in improving oral health. PMID- 29461635 TI - Clinical and mutational spectrum of highly differentiated, paired box 3:forkhead box protein o1 fusion-negative rhabdomyosarcoma: A report from the Children's Oncology Group. AB - BACKGROUND: Pediatric paired box 3:forkhead box protein O1 fusion-negative (PF-) rhabdomyosarcoma (RMS) represents a diverse spectrum of tumors with marked differences in histology, myogenic differentiation, and clinical behavior. METHODS: This study sought to evaluate the clinical and mutational spectrum of 24 pediatric PF- human RMS tumors with high levels of myogenic differentiation. Tumors were sequenced with OncoPanel v.2, a panel consisting of the coding regions of 504 genes previously linked to human cancer. RESULTS: Most of the tumors (19 of 24) arose at head/neck or genitourinary sites, and the overall survival rate was 100% with a median follow-up time of 4.6 years (range, 1.4-8.6 years). RAS pathway gene mutations were the most common mutations in PF-, highly differentiated RMS tumors. In addition, Hedgehog (Hh) and mechanistic target of rapamycin (mTOR) gene mutations with evidence for functional relevance (high impact) were identified in subsets of tumors. The presence of Hh and mTOR pathway gene mutations was mutually exclusive and was associated with high-impact RAS pathway gene mutations in 3 of 4 Hh-mutated tumors and in 1 of 6 mTOR-mutated tumors. CONCLUSIONS: Interestingly, Hh and mTOR gene mutations were previously associated with rhabdomyomas, which are also known to preferentially arise at head/neck and genitourinary sites. Findings from this study further support the idea that PF-, highly differentiated RMS tumors and rhabdomyomas may represent a continuous spectrum of tumors. Cancer 2018;124:1973-81.

AB - We assessed mothers' self-reported gains from a postpartum home-visiting (HV) project in which home visitors are volunteer mothers from the community. Hypotheses were that gains are positively related to (a) mothers' felt-closeness with their home visitor, (b) mothers' level of sociodemographic risk, and (c) the home visitors' preproject training in support services for families or children (Professionalism). One hundred sixty-four clients returned written evaluations of the HV project. Items assessing gains were reduced to two factors: Improved Well Being ("Self") and Improved Infant Care ("Infant"). Repeated measures general linear models, with Gains (Self, Infant) as the repeated measure, and multiple regression analyses evaluated the hypotheses. Across the sample, gains on both factors were moderate, although gain scores were higher regarding Self than for Infant. Results show that (a) Mothers' felt-closeness with their volunteer was strongly related to mothers' gains; (b) high-risk mothers gained more from the project than did mothers of lower risk, particularly regarding Infant Care; and (c) mothers visited by volunteers who were professionals reported more substantial gains than did mothers visited by volunteers who were not professionals. Findings can help explain variance in mothers' gains from such projects and could be useful in improving their efficacy. PMID- 29461638 TI - Dynamic changes in display architecture and function across environments revealed by a systems approach to animal communication. AB - Animal communication is often structurally complex and dynamic, with signaler and receiver behavior varying in response to multiple environmental factors. To date, studies assessing signal dynamics have mostly focused on the relationships between select signaling traits and receiver responses in a single environment. We use the wolf spider Schizocosa floridana to explore the relationships between courtship display form and function across two social contexts (female presence vs absence) and two light environments (light vs dark). We use traditional analytical methods to determine predictors of copulation success (i.e., signal function) and examine these predictors in a structural context by overlaying them on signal phenotype networks (Wilkins et al. 2015). This allows us to explore system design principles (degeneracy, redundancy, pluripotentiality), providing insight into hypotheses regarding complex signal evolution. We found that both social context and light environment affect courtship structure, although the predictors of mating success remain similar across light environments, suggesting system degeneracy. Contrastingly, the same display traits may serve different functions across social environments, suggesting pluripotentiality. Ultimately, our network approach uncovers a complexity in display structure and function that is missed by functional analyses alone, highlighting the importance of systems based methodologies for understanding the dynamic nature of complex signals. PMID- 29461639 TI - Impact of the affordability of novel agents in patients with multiple myeloma: Real-world data of current clinical practice in Mexico. AB - BACKGROUND: The treatment of multiple myeloma (MM) has become costly and difficult to access for patients living in low-income to middle-income countries. METHODS: The current retrospective study included 148 patients in Mexico with newly diagnosed MM, and was performed to compare the outcomes of patients with and without access to novel agents. The records of 77 patients admitted to a public hospital (PubC) and 71 patients cared for within private health systems (PrivC) from November 2007 to July 2016 were reviewed. RESULTS: Compared with those treated in PrivC, patients receiving care at PubC were more likely to be diagnosed with advanced disease. A thalidomide-based regimen was the most common induction treatment used at PubC, whereas a bortezomib-based regimen was used most often in PrivC. The median follow-up was 41 months. Patients in PrivC demonstrated better response rates and survival; 65% of patients treated in PrivC versus 41% treated at PubC achieved a very good partial response or better (P = .005). The median progression-free survival and median overall survival were 23 months and 51 months, respectively, for patients treated at PubC and 41 months and 79 months, respectively, for those treated in PrivC (P<.001). More patients underwent autologous stem cell transplantation in PrivC. When adjustments were made for covariates, patients treated at PubC experienced a higher risk of death compared with patients receiving care in PrivC (hazard ratio, 2.0; 95% confidence interval, 1.0-4.3 [P = .04]). CONCLUSIONS: Stage at diagnosis, induction regimen, and autologous stem cell transplantation were found to be contributors to survival disparities between patients with MM treated at PubC compared with PrivC in Mexico. These findings underscore the need to improve access to novel agents and stem cell transplantation in public health systems. Cancer 2018;124:1946-53. (c) 2018 American Cancer Society.

AB - : The near infrared (NIR) spectroscopy as the rapid nondestructive method was aimed to be applied for determination of the texture properties of melon intact fruit and pulp including initial firmness, rupture force, average firmness, rupture distance, toughness, average penetrating force and penetrating energy. The data from the reference method of texture analyzer were correlated with the NIR spectral data. The result showed that, only the two properties including rupture force and penetrating force in pulp could be predicted by NIR spectroscopy technique. The determination coefficient of validation (r2 ) for prediction of rupture force and penetrating force in the pulp of melon using intact fruit spectra were 0.850 and 0.845, respectively. The r2 , for prediction of rupture force and penetrating force in the pulp of melon using pulp spectra were 0.813 and 0.778, respectively. This indicated that the NIR spectroscopy protocol developed here was useful for research works such as breeding and postharvest research, the melon processing factory and also the import and export of melon. PRACTICAL APPLICATIONS: The near infrared spectroscopy protocol developed for determination of rupture force and penetrating force in pulp using intact fruit spectra as a nondestructive method will be useful for research works such as breeding and postharvest research, the melon processing factory and also the import and export of melon. There are also the protocol developed using pulp spectra can be used for texture determination of fresh-cut melon. PMID- 29461641 TI - Mutational studies of the Aux/IAA proteins in Physcomitrella reveal novel insights into their function. AB - The plant hormone auxin regulates many aspects of plant growth and development. Auxin signaling involves hormone perception by the TRANSPORT INHIBITOR RESPONSE/AUXIN F-BOX (TIR1/AFB)-Aux/IAA co-receptor system, and the subsequent degradation of the Aux/IAA transcriptional repressors by the ubiquitin proteasome pathway. This leads to the activation of downstream gene expression and diverse physiological responses. Here, we investigate how the structural elements in the Aux/IAAs determine their function in Auxin perception and transcriptional repression. We took advantage of the facile genetics of the moss Physcomitrella patens to determine the activity of wild-type and mutant PpIAA1a proteins in a Deltaaux/iaa null background. In this way, Aux/IAA function was characterized at the molecular and physiological levels without the interference of genetic redundancy. We identified and characterized degron variants in Aux/IAAs that affect their stability and Auxin response. We also demonstrated that neither the Aux/IAA EAR motif nor Aux/IAA oligomerization is essential for the repressive function of Aux/IAA. Our study demonstrates how key elements within the Aux/IAA proteins fine tune stability and repressor activity, as well as the long-term developmental outcome. PMID- 29461642 TI - Brachial plexitis or neuritis? MRI features of lesion distribution in Parsonage Turner syndrome. AB - INTRODUCTION: This study seeks to characterize lesion distribution in Parsonage Turner Syndrome (PTS) using high-resolution MRI. METHODS: MRIs of 27 patients with clinically confirmed PTS were reviewed. Two radiologists independently evaluated the brachial plexus proper, side and terminal plexus branches, and more distal, upper extremity nerves. RESULTS: All patients had at least 1 clinically involved nerve. MRI revealed that the plexus appeared normal in 24 of 27 patients; in 3 other patients, signal hyperintensity was seen immediately proximal to the take-off of abnormal side or terminal branch nerves. Focal intrinsic constrictions were detected in 32 of 38 nerves. MRI interobserver agreement was high (Cohen's kappa = 0.839). DISCUSSION: MRI findings, corroborated by electrodiagnostic testing, localized abnormalities to plexus branches and peripheral nerves, suggesting that PTS is characterized by 1 or more mononeuropathies rather than changes involving a portion of or the complete plexus proper. These results may improve diagnosis, prognostication, and management. Muscle Nerve 58: 359-366, 2018. PMID- 29461644 TI - RasGRP3, a Ras guanyl releasing protein 3 that contributes to malignant proliferation and aggressiveness in human esophageal squamous cell carcinoma. AB - Esophageal squamous cell carcinoma (ESCC) is one of the most common cancers worldwide; however, clinical and pathological parameters have limited ability in discriminating between clinically significant and indolent ESCC. Since RasGRP3 transcript levels have prognostic value in discriminating ESCC with different clinical aggressiveness, we decided to investigate its putative oncogenic role in ESCC. We found that RasGRP3 was highly expressed in ESCC cells. Suppression of endogenous RasGRP3 expression in esophageal cell lines reduced Ras-GTP formation as well as AKT phosphorylation. RasGRP3 suppression also inhibited cell invasion and migration and reduced proliferation, demonstrating the importance of RasGRP3 for the transformed phenotype of melanoma cells. Suppression of RasGRP3 expression in these cells inhibited downstream RasGRP3 responses and suppressed cell growth and migration, confirming the functional role of RasGRP3 in the altered behaviour of these cells. This suggests that RasGRP3 may function as a Ras activator in the phosphoinositide signalling pathway and may potentially serve as a new therapeutic target. PMID- 29461643 TI - Dysregulation of NEUROG2 plays a key role in focal cortical dysplasia. AB - OBJECTIVE: Focal cortical dysplasias (FCDs) are an important cause of drug resistant epilepsy. In this work, we aimed to investigate whether abnormal gene regulation, mediated by microRNA, could be involved in FCD type II. METHODS: We used total RNA from the brain tissue of 16 patients with FCD type II and 28 controls. MicroRNA expression was initially assessed by microarray. Quantitative polymerase chain reaction, in situ hybridization, luciferase reporter assays, and deep sequencing for genes in the mTOR pathway were performed to validate and further explore our initial study. RESULTS: hsa-let-7f (p = 0.039), hsa-miR-31 (p = 0.0078), and hsa-miR34a (p = 0.021) were downregulated in FCD type II, whereas a transcription factor involved in neuronal and glial fate specification, NEUROG2 (p < 0.05), was upregulated. We also found that the RND2 gene, a NEUROG2-target, is upregulated (p < 0.001). In vitro experiments showed that hsa-miR-34a downregulates NEUROG2 by binding to its 5'-untranslated region. Moreover, we observed strong nuclear expression of NEUROG2 in balloon cells and dysmorphic neurons and found that 28.5% of our patients presented brain somatic mutations in genes of the mTOR pathway. INTERPRETATION: Our findings suggest a new molecular mechanism, in which NEUROG2 has a pivotal and central role in the pathogenesis of FCD type II. In this way, we found that the downregulation of hsa-miR-34a leads to upregulation of NEUROG2, and consequently to overexpression of the RND2 gene. These findings indicate that a faulty coupling in neuronal differentiation and migration mechanisms may explain the presence of aberrant cells and complete dyslamination in FCD type II.

PMID- 29461645 TI - Enzymatic or In Vivo Installation of Propargyl Groups in Combination with Click Chemistry for the Enrichment and Detection of Methyltransferase Target Sites in RNA. AB - m6 A is the most abundant internal modification in eukaryotic mRNA. It is introduced by METTL3-METTL14 and tunes mRNA metabolism, impacting cell differentiation and development. Precise transcriptome-wide assignment of m6 A sites is of utmost importance. However, m6 A does not interfere with Watson-Crick base pairing, making polymerase-based detection challenging. We developed a chemical biology approach for the precise mapping of methyltransferase (MTase) target sites based on the introduction of a bioorthogonal propargyl group in vitro and in cells. We show that propargyl groups can be introduced enzymatically by wild-type METTL3-METTL14. Reverse transcription terminated up to 65 % at m6 A sites after bioconjugation and purification, hence enabling detection of METTL3 METTL14 target sites by next generation sequencing. Importantly, we implemented metabolic propargyl labeling of RNA MTase target sites in vivo based on propargyl l-selenohomocysteine and validated different types of known rRNA methylation sites. PMID- 29461646 TI - Younger age and in situ duration of peripheral intravenous catheters were risk factors for extravasation in a retrospective paediatric study. AB - AIM: Epidemiological data on the incidence and risk factors of extravasation of peripheral intravenous catheters (PIVC) in neonates and children are scarce and that is what this study explored. METHODS: This was a one-year retrospective study of all neonates and paediatric intensive care patients with at least one recorded PIVC at the Geneva University Hospitals, Switzerland, in 2013. The extravasation rate was determined for all patients, including neonates below 28 days, and for all PIVCs. Multivariate analysis of the associated risk factors was performed. RESULTS: We analysed 1300 PIVC in 695 paediatric patients with a median age of 1.5 years. The overall extravasation incidence was 17.6% for all patients and 11.7% for PIVC. The overall incidence rate of PIVC extravasation was 4.5 per 100 catheters days, and the risk was highest in the 201 neonates, at 28.4%. The incidence rate four days after insertion of the PIVC was around three times higher than on day one. Neonates and the in situ duration of PIVCs were associated risk factors (p < 0.001). CONCLUSION: Extravasation was frequent and neonates were particularly at risk. Younger age and longer in situ PIVC duration were independent risk factors for extravasation. PMID- 29461647 TI - Comparison of three dehydration scales showed that they were of limited or no value for assessing small children with acute diarrhoea. AB - AIM: We explored the diagnostic accuracy of the clinical dehydration scale (CDS), the World Health Organization (WHO) scale and the Gorelick scale for assessing dehydration in children admitted to a Tanzanian referral hospital. METHODS: This was a prospective, observational study, carried out from April 2015 to January 2017 on children aged one month to five years admitted to the hospital with acute diarrhoea lasting less than five days. Before rehydration therapy, each patient's weight was recorded and the degree of dehydration was assessed based on the three scales. The reference standard was the percentage weight change between admission and discharge. The main outcomes were the sensitivity, specificity and positive and negative likelihood ratios (LRs) of the scales. RESULTS: Data from 124 eligible patients were available. The CDS showed limited value for ruling in cases with some dehydration (LR 1.9, 95% confidence interval 1.1-2.8), but was of no value in assessing no and moderate to severe dehydration. The WHO and Gorelick scales were of no value in evaluating any degree of dehydration. CONCLUSION: The WHO and Gorelick dehydration scales were no use for assessing dehydration in small children, and the CDS was of limited use for predicting cases with some dehydration.

AB - An unprecedented dearomatized spirocyclopropane intermediate was discovered in a sequential Cp*RhIII -catalyzed C-H activation and Wagner-Meerwein-type rearrangement reaction. How the oxidative O-N bond is cleaved and the role of HOAc were uncovered in this study. Furthermore, a Cp*RhIII -catalyzed dearomatization reaction of N-(naphthalen-1-yloxy)acetamide with strained olefins was developed, affording a variety of spirocyclopropanes. PMID- 29461649 TI - Contextual and stress process factors associated with head and neck cancer caregivers' physical and psychological well-being. AB - Head and neck cancer (HNC) caregivers are especially vulnerable to poor outcomes because the HNC patients are at high risk for physical and functional impairments. This study examines contextual and stress process variables potentially associated with HNC caregivers' physical and psychological well being. Patient-caregiver variables included socio-demographics, primary stressors (caregiving, patient clinical characteristics, HNC-related symptoms/dysfunction), secondary stressors (caregiver employment, childcare responsibilities and sleep duration <7 hr), appraisal, and response (physical activity). General linear models modeled caregiver well-being, along with depression and anxiety. A total of 33 patient-caregiver dyads were included. Most caregivers were female (81.8%) and patient spouses/partners (72.7%). Factors significantly associated with better caregiver physical well-being included caregiver older age, <2 comorbidities, >=7 hr of sleep, >=3 days/week physical activity, and patient swallowing and speech dysfunction. Factors significantly associated with better caregiver mental health functioning were less patient social dysfunction and less perceived caregiving burden. Short nighttime sleep, higher caregiver burden, and <3 days/week physical activity were also significantly related to caregivers' depression and anxiety. Results suggested caregiver behaviors and perceived burden, along with patient HNC concerns are linked with caregiver well-being. These behavioral, cognitive, and patient factors should be incorporated into caregiver screening tools or targeted with behavioral interventions to improve caregiver well-being. PMID- 29461651 TI - Children living in the slums of Bangladesh face risks from unsafe food and water and stunted growth is common. AB - AIM: This study investigated the microbial quality of food and water consumed by children in four slums in Dhaka, the capital of Bangladesh, together with the associated risk factors. METHODS: This cross-sectional study took place from December 2015 to May 2016 and focused on 360 children under the age of five. We recorded household food security, namely adequate food for a healthy life, socio economic and nutritional status, hygiene and feeding practices. Food and water samples were analysed. RESULTS: We found that 63% of the children were malnourished and 58% were stunted. Yeast and moulds were detected in 86% of the food samples and coliforms in 73%. All the water samples were contaminated with faecal coliforms, yeasts and moulds and Staphylococcus. Food insecurity affected 83% of households. Children were twice as likely to be malnourished if they were born with a perceived low birthweight or their mothers did not wash their hands with soap after cleaning the child's bottom following defecation. Exclusively breastfed children were less likely to develop malnutrition. CONCLUSION: Children from the Dhaka slums were frequently stunted and malnourished and contaminated food and water was common. Integrated efforts are essential to create public awareness about hygiene. PMID- 29461652 TI - The impact of sexual orientation on body image, self-esteem, urinary and sexual functions in the experience of prostate cancer. AB - Prostate cancer (PCa) poses a large health burden globally. Research indicates that men experience a range of psychological challenges associated with PCa including changes to identity, self-esteem and body image. The ways in which sexual orientation plays a role in the experience of PCa, and the subsequent impact on quality of life (QoL), body image and self-esteem have only recently been addressed. By addressing treatment modality, where participant numbers were sufficient, we also sought to explore whether gay (homosexual) men diagnosed with PCa (PCaDx) and with a primary treatment modality of surgery would report differences in body image and self-esteem compared with straight (heterosexual) men with PCaDx with a primary treatment modality of surgery, compared with gay and straight men without PCaDx. The results of our study identified overall differences with respect to PCaDx (related to urinary function, sexual function and health evaluation), and sexual orientation (related to self-esteem), rather than interactions between sexual orientation and PCaDx. Gay men with PCaDx exhibited higher levels of urinary functioning than straight men with PCaDx, the difference being reversed for gay and straight men without PCaDx; but this result narrowly failed to achieve statistical significance, suggesting a need for further research, with larger samples. PMID- 29461650 TI - Sex matters: females in proestrus show greater diazepam anxiolysis and brain derived neurotrophin factor- and parvalbumin-positive neurons than males. AB - In humans and animal models, sex differences are reported for anxiety-like behavior and response to anxiogenic stimuli. In the current work, we studied anxiety-like behavior and response to the prototypical anti-anxiety drug, diazepam. We used 6th generation outbred lines of adult Long Evans rats with high and low anxiety-like behavior phenotypes to investigate the impact of proestrus on the baseline and diazepam-induced behavior. At three doses of diazepam (0, 0.1, and 1.0 mg/kg, i.p.), we measured anxiogenic responses on the elevated plus maze of adult male and female rats. We assessed parvalbumin and brain-derived neurotrophin protein levels in forebrain and limbic structures implicated in anxiety/stress using immunohistochemistry. At baseline, we saw significant differences between anxiety lines, with high anxiety lines displaying less time on the open arms of the elevated plus maze, and less open arm entries, regardless of sex. During proestrus, high anxiety females showed less anxiety-like behavior at 0.1 mg/kg, while low anxiety females displayed less anxiety-like behavior at 0.1 and 1.0 doses, relative to males. Brain-derived neurotrophin protein was elevated in females in the medial prefrontal cortex and central amygdala, while parvalbumin-immunoreactive cells were greater in males in the medial prefrontal cortex. Parvalbumin-positive cells in high anxiety females were higher in CA2 and dentate gyrus relative to males from the same line. In sum, when tested in proestrus, females showed greater anxiolytic effects of diazepam relative to males, and this correlated with increases in neurotrophin and parvalbumin neuron density in corticolimbic structures. PMID- 29461653 TI - Epigenetic marks of in utero exposure to gestational diabetes and childhood adiposity outcomes: the EPOCH study. AB - AIMS: To identify gestational diabetes mellitus exposure-associated DNA methylation changes and assess whether such changes are also associated with adiposity-related outcomes. METHODS: We performed an epigenome-wide association analysis, using Illumina 450k methylation arrays, on whole blood collected, on average, at 10.5 years of age from 81 gestational diabetes-exposed and 81 unexposed offspring enrolled in the EPOCH (Exploring Perinatal Outcomes in Children) study, and on the cord blood of 31 gestational diabetes-exposed and 64 unexposed offspring enrolled in the Colorado Healthy Start cohort. Validation was performed by pyrosequencing. RESULTS: We identified 98 differentially methylated positions associated with gestational diabetes exposure at a false discovery rate of <10% in peripheral blood, with 51 loci remaining significant (plus additional 40 loci) after adjustment for cell proportions. We also identified 2195 differentially methylation regions at a false discovery rate of <5% after adjustment for cell proportions. We prioritized loci for pyrosequencing validation and association analysis with adiposity-related outcomes based on strengths of association and effect size, network and pathway analysis, analysis of cord blood, and previous publications. Methylation in six out of nine (67%) gestational diabetes-associated genes was validated and we also showed that methylation of SH3PXD2A was significantly (P<0.05) associated with multiple adiposity-related outcomes. CONCLUSIONS: Our findings suggest that epigenetic marks may provide an important link between in utero exposure to gestational diabetes and obesity in childhood, and add to the growing body of evidence that DNA methylation is affected by gestational diabetes exposure. PMID- 29461654 TI - Acute responses to structured aerobic and resistance exercise in women with gestational diabetes mellitus. AB - Research on the acute responses to exercise in pregnancy is scarce, especially for women affected by gestational diabetes mellitus (GDM). The aim of this study was to investigate responses to a single bout of exercise performed multiple times throughout the pregnancy in women diagnosed with GDM. Data from 18 pregnant women (aged: 32.8 +/- 3.8) diagnosed with GDM, treated with diet only, were analyzed. Participants' pre-pregnancy body mass index was 24.4 +/- 4.9 kg/m2 , 50% of them were nulliparous, and 50% of the sample regularly exercised before the pregnancy. The exercise intervention consisted of an individual structured aerobic and resistance exercise program performed twice per week from the time of diagnosis until at least the 36th week of pregnancy. The exercise program included 20 minutes of aerobic exercise, 20-25 minutes of resistance exercise, and 10 minutes of cool down. Maternal heart rate, systolic and diastolic blood pressure, temperature and fetal heart rate were measured at every exercise session, along with blood glucose on 3 occasions. In total, 365 exercise sessions were analyzed (85 in the second trimester and 280 in the third trimester), on average 20.3 +/- 7.7 per participant. Heart rate and fetal heart rate were elevated during both the aerobic and resistance parts of the exercise session (P < .01) in comparison with the baseline while systolic and diastolic blood pressure did not change in the total sample. There was a slight elevation in tympanic membrane temperature during the aerobic part of the session (P < .01). All parameters returned to baseline levels by the end of the session. Glucose levels dropped from the baseline, from 4.7 +/- 0.6 to 3.9 +/- 0.4 mmol/L (P < .01). There were no differences in responses to exercise between the second and third trimesters, nor between pre-pregnancy exercisers and non-exercisers. The combination of aerobic and resistance exercise for women diagnosed with GDM does not have harmful short-term effects if performed according to guidelines. Likewise, exercise can be considered useful for controlling hyperglycemia in pregnancy for women affected by GDM. PMID- 29461656 TI - Identification and characterization of acetyltransferase-type toxin-antitoxin locus in Klebsiella pneumoniae. AB - A type II toxin-antitoxin (TA) system, in which the toxin contains a Gcn5-related N-acetyltransferase (GNAT) domain, has been characterized recently. GNAT toxin acetylates aminoacyl-tRNA and blocks protein translation. It is abolished by the cognate antitoxin that contains the ribbon-helix-helix (RHH) domain. Here, we present an experimental demonstration of the interaction of the GNAT-RHH complex with TA promoter DNA. First, the GNAT-RHH TA locus kacAT was found in Klebsiella pneumoniae HS11286, a strain resistant to multiple antibiotics. Overexpression of KacT halted cell growth and resulted in persister cell formation. The crystal structure also indicated that KacT is a typical acetyltransferase toxin. Co expression of KacA neutralized KacT toxicity. Expression of the bicistronic kacAT locus was up-regulated during antibiotic stress. Finally, KacT and KacA formed a heterohexamer that interacted with promoter DNA, resulting in negative autoregulation of kacAT transcription. The N-terminus region of KacA accounted for specific binding to the palindromic sequence on the operator DNA, whereas its C-terminus region was essential for the inactivation of the GNAT toxin. These results provide an important insight into the regulation of the GNAT-RHH family TA system. PMID- 29461655 TI - Exploring the rationale for combining ionizing radiation and immune checkpoint blockade in head and neck cancer. AB - BACKGROUND: The ability of radiation to enhance antitumor immunity under specific experimental conditions is well established. Here, we explore preclinical data and the rationale for combining different radiation doses and fractions with immune checkpoint blockade immunotherapy. METHODS: We conducted a review of the literature. RESULTS: The ability of high-dose or hypofractionated radiation to enhance antitumor immunity resulting in additive or synergistic tumor control when combined with checkpoint blockade is well studied. Whether low-dose daily fractionated radiation does the same is less well studied and available data suggests it may be immunosuppressive. CONCLUSION: Although daily fractionated radiation is well established as the standard of care for the treatment of patients with head and neck cancer, how this radiation schema alters antitumor immunity needs further study. If the radiation doses and fractions alter antitumor immunity differently can have profound implications in the rational design of clinical trials investigating whether radiation can enhance response rates to immune checkpoint blockade. PMID- 29461657 TI - Vestibular modulation of peripersonal space boundaries. AB - Human-environment interactions are mediated through the body and occur within the peripersonal space (PPS), the space immediately adjacent to and surrounding the body. The PPS is taken to be a critical interface between the body and the environment, and indeed, body-part specific PPS remapping has been shown to depend on body-part utilization, such as upper limb movements in otherwise static observers. How vestibular signals induced by whole-body movement contribute to PPS representation is less well understood. In a series of experiments, we mapped the spatial extension of the PPS around the head while participants were submitted to passive whole-body rotations inducing vestibular stimulation. Forty six participants, in three experiments, executed a tactile detection reaction time task while task-irrelevant auditory stimuli approached them. The maximal distance at which the auditory stimulus facilitated tactile reaction time was taken as a proxy for the boundary of peri-head space. The present results indicate two distinct vestibular effects. First, vestibular stimulation speeded tactile detection indicating a vestibular facilitation of somatosensory processing. Second, vestibular stimulation modulated audio-tactile interaction of peri-head space in a rotation direction-specific manner. Congruent but not incongruent audio-vestibular motion stimuli expanded the PPS boundary further away from the body as compared to no rotation. These results show that vestibular inputs dynamically update the multisensory delineation of PPS and far space, which may serve to maintain accurate tracking of objects close to the body and to update spatial self-representations. PMID- 29461658 TI - One-Pot Tandem Photoredox and Cross-Coupling Catalysis with a Single Palladium Carbodicarbene Complex. AB - The combination of conventional transition-metal-catalyzed coupling (2 e- process) and photoredox catalysis (1 e- process) has emerged as a powerful approach to catalyze difficult cross-coupling reactions under mild reaction conditions. Reported is a palladium carbodicarbene (CDC) complex that mediates both a Suzuki-Miyaura coupling and photoredox catalysis for C-N bond formation upon visible-light irradiation. These two catalytic pathways can be combined to promote both conventional transition-metal-catalyzed coupling and photoredox catalysis to mediate C-H arylation under ambient conditions with a single catalyst in an efficient one-pot process. PMID- 29461659 TI - Live Imaging of Type I Collagen Assembly Dynamics in Osteoblasts Stably Expressing GFP and mCherry-Tagged Collagen Constructs. AB - Type I collagen is the most abundant extracellular matrix protein in bone and other connective tissues and plays key roles in normal and pathological bone formation as well as in connective tissue disorders and fibrosis. Although much is known about the collagen biosynthetic pathway and its regulatory steps, the mechanisms by which it is assembled extracellularly are less clear. We have generated GFPtpz and mCherry-tagged collagen fusion constructs for live imaging of type I collagen assembly by replacing the alpha2(I)-procollagen N-terminal propeptide with GFPtpz or mCherry. These novel imaging probes were stably transfected into MLO-A5 osteoblast-like cells and fibronectin-null mouse embryonic fibroblasts (FN-null-MEFs) and used for imaging type I collagen assembly dynamics and its dependence on fibronectin. Both fusion proteins co precipitated with alpha1(I)-collagen and remained intracellular without ascorbate but were assembled into alpha1(I) collagen-containing extracellular fibrils in the presence of ascorbate. Immunogold-EM confirmed their ultrastuctural localization in banded collagen fibrils. Live cell imaging in stably transfected MLO-A5 cells revealed the highly dynamic nature of collagen assembly and showed that during assembly the fibril networks are continually stretched and contracted due to the underlying cell motion. We also observed that cell-generated forces can physically reshape the collagen fibrils. Using co-cultures of mCherry- and GFPtpz-collagen expressing cells, we show that multiple cells contribute collagen to form collagen fiber bundles. Immuno-EM further showed that individual collagen fibrils can receive contributions of collagen from more than one cell. Live cell imaging in FN-null-MEFs expressing GFPtpz-collagen showed that collagen assembly was both dependent upon and dynamically integrated with fibronectin assembly. These GFP-collagen fusion constructs provide a powerful tool for imaging collagen in living cells and have revealed novel and fundamental insights into the dynamic mechanisms for the extracellular assembly of collagen.

PMID- 29461660 TI - Outcomes at 7 years post-transplant in black vs nonblack kidney transplant recipients administered belatacept or cyclosporine in BENEFIT and BENEFIT-EXT. AB - Clinical outcomes are generally worse for black vs nonblack renal allograft recipients. In BENEFIT and BENEFIT-EXT, recipients were randomized to belatacept more intense-based, belatacept less intense-based, or cyclosporine-based immunosuppression. At year 7, belatacept was associated with superior graft survival vs cyclosporine in BENEFIT (recipients of living or standard criteria deceased donor kidneys); belatacept was associated with similar graft survival vs cyclosporine in BENEFIT-EXT (recipients of extended criteria donor kidneys). In both studies, renal function was superior for belatacept-treated vs cyclosporine treated patients. Seven-year outcomes were examined by race post hoc in each study. The effect of race and treatment on time to death or graft loss was compared using Cox regression. The interaction between treatment and race was also considered. Glomerular filtration rate (GFR) was estimated from months 1 to 84 using a repeated-measures model. In total, 8.3% (55/666) and 13.1% (71/543) of patients in BENEFIT and BENEFIT-EXT, respectively, were black. Time to death or graft loss was similar in blacks and nonblacks. For both subgroups, estimated mean GFR increased over 7 years for belatacept, but declined for cyclosporine. Outcomes were similar in belatacept-treated black and nonblack patients. Due to the small number of black patients, these results must be interpreted with caution. PMID- 29461661 TI - Preoperative imaging for parathyroid localization in patients with concurrent thyroid disease: A systematic review. AB - BACKGROUND: Thyroid disease occurs more frequently in patients with hyperparathyroidism than the general population and hinders parathyroid localization. Identifying thyroid pathology before operating improves management and avoids the risks of reoperation in the neck. This review assesses imaging studies in patients with hyperparathyroidism and thyroid pathology to identify the ideal imaging methodology for patients with multigland disease. METHODS: Systematic review of original articles reporting sensitivity or positive predictive value (PPV) for one or more imaging modalities in patients with hyperparathyroidism and thyroid disease. RESULTS: Twenty-eight studies, 13 prospective and 15 retrospective, met inclusion criteria. Nine modalities were evaluated, including: cervical ultrasound (n = 18), dual-phase 99m Tc-sestamibi (n = 14), subtraction scintigraphy (n = 11), combined ultrasound and scintigraphy (n = 8), single photon emission CT (SPECT; n = 5), SPECT-CT (n = 4), contrast enhanced ultrasound (n = 1), CT (n = 1), and MRI (n = 1). CONCLUSION: Combined ultrasound and scintigraphy is the most sensitive study to localize parathyroid adenomas in patients with hyperparathyroidism and thyroid disease, followed by hybrid SPECT-CT and SPECT.

AB - The first Lewis acid catalyzed enantioselective ring-opening desymmetrization of a donor-acceptor meso-diaminocyclopropane is reported. The copper(II)-catalyzed Friedel-Crafts alkylation of indoles and one pyrrole with an unprecedented meso diaminocyclopropane delivered enantioenriched, diastereomerically pure urea products, which are structurally related to natural and synthetic bioactive compounds. The development of a new ligand through the investigation of an underexplored subclass of bis(oxazoline) ligands was essential for achieving high enantioselectivities. PMID- 29461663 TI - Ullazine Donor-pi bridge-Acceptor Organic Dyes for Dye-Sensitized Solar Cells. AB - A series of four ullazine-donor based donor-pi bridge-acceptor (D-pi-A) dyes have been synthesized and compared to a prior ullazine donor-acceptor (D-A) dye as well as a triphenylamine donor with an identical pi-bridge and acceptor. The D-pi A ullazine series demonstrates an unusually uniform-in-intensity panchromatic UV/Vis absorption spectrum throughout the visible region. This is in part due to the introduction of strong high-energy bands through incorporation of the ullazine building block as shown by computational analysis. The dyes were characterized on TiO2 films and in DSC devices. Performances of 5.6 % power conversion efficiency were obtained with IPCE onsets reaching 800 nm. PMID- 29461664 TI - Validation of the Chinese version of EORTC QLQ-BN20 for patients with brain cancer. AB - This is a single centre study in mainland China aiming to evaluate the reliability, validity and responsiveness of the Chinese version of EORTC QLQ BN20, designed by The European Organization for Research and Treatment of Cancer Quality of Life Group to evaluate the life quality of patients with brain tumour, cancer or metastases. One hundred and eighty-eight patients with primary or secondary brain cancer from Hunan Provincial Tumor Hospital during September 2013 to June 2014 completed the Chinese EORTC QLQ-C30/BN20 questionnaires developed by translation, back translation and cultural adaptation. Results were statistically analysed using SPSS17.0. The internal consistency (Cronbach's alpha coefficient) was between .753 and .869, the correlation coefficients among items and its own dimension were bigger than .4, and all items had a better correlation with its own dimension. The Spearman was used to analyse the correlation of each dimension between EORTC QLQ-BN20 and EORTC QLQ-C30, and the result showed that individual dimensions were moderately correlated, other dimensions were weakly correlated. In conclusion, the Chinese version of EORTC QLQ BN20 questionnaire had great relevance, reliability, convergent validity and discriminant validity. It provides a valuable tool for the assessment of health-related quality of life in clinical studies of Chinese patients with primary or secondary brain cancer. PMID- 29461665 TI - Children with cow's milk allergy following an elimination diet had normal growth but relatively low plasma leptin at age two. AB - AIM: To assess nutrient intake, growth and nutritional status of infants with cow's milk allergy (CMA) who follow a therapeutic elimination diet since the first few months of life. METHODS: Sixty infants younger than four months of age with challenge-proven CMA and 60 healthy age-matched children were investigated. Anthropometric and body composition (BC) were assessed up to 24 months. Dietary intake was recorded by the parents for three consecutive days before visits at 6, 12, 18 and 24 months. Blood albumin, prealbumin, retinol binding protein and metabolic-related hormones were examined at 24 months. RESULTS: The average age at enrolment was 2.9 +/- 1.0 months. At the end of the follow-up, there were no differences in daily milk consumption, nutrient intake, weight and height z scores or BC measures between the groups; however, the plasma leptin level was lower in infants with CMA (1.67 +/- 1.03 vs 2.05 +/- 1.48) (ng/mL) (p < 0.05) compared to healthy children. CONCLUSIONS: Children with CMA who followed an elimination diet could achieve a normal nutritional status, except for relatively lower plasma leptin levels, at the age of 2. Further studies with larger cohorts and research on the long-term consequences of these early differences are needed.

PMID- 29461667 TI - Computer vision detects subtle histological effects of dutasteride on benign prostate. AB - OBJECTIVE: To determine whether a computer vision-based approach applied to haematoxylin and eosin (H&E) prostate biopsy images can distinguish dutasteride treated tissue from placebo, and identify features associated with degree of responsiveness to 5alpha-reductase inhibitor (5ARI) therapy. SUBJECTS AND METHODS: Our study population comprised 100 treatment-adherent men without prostate cancer assigned to dutasteride or placebo in the REDUCE trial, who had slides available from mandatory year-4 biopsies. Half of the men also provided slides from a year-2 biopsy. We obtained 20* whole-slide images and used specialized software to generate a library of 1 300 epithelial and stromal features from objects comprising superpixels and several types of nuclei, including spatial relations among objects between and within each hierarchical level. We used penalized logistic regression and fivefold cross-validation to find optimal combinations of histological features in the year-4 biopsies. Feature data from the year-2 biopsies were fitted to a final model for independent validation. Two pathologists, blinded to treatment, scored each image for focal atrophy and histological features previously linked to 5AR1 treatment. RESULTS: Consensus classification by pathologists obtained a discrimination accuracy equivalent to chance. A 21-feature computer vision model gave a cross validation area under the curve of 0.97 (95% confidence interval [CI] 0.95-0.99) in the year-4 biopsies and 0.79 (95% CI: 0.65-0.92) in the set-aside year-2 biopsies. Histology scores were not correlated with change in prostate-specific antigen level, serum dihydrotestosterone level or gland volume. Key features associated with dutasteride treatment included greater shape and colour uniformity in stroma, irregular clustering of epithelial nuclei, and greater variation in lumen shape. CONCLUSION: The present findings show that a computer vision approach can detect subtle histological effects attributable to dutasteride, resulting in a continuous measure of responsiveness to the drug that could eventually be used to predict individual patient response in the context of BPH treatment or cancer chemoprevention. PMID- 29461668 TI - Time-lapse imaging points towards a non-toxic, mainly immune-driven mode of action of ingenol mebutate in the treatment of anogenital warts. AB - Recently, it has been reported that ingenol mebutate (IM) is an effective treatment option for anogenital warts (AGW), inducing fast wart necrosis within 24 hours in vivo. With regard to its mode of action, IM is thought to act both as an inducer of direct cytotoxic effects and immunologic mechanisms. To distinguish whether the wart necrosis is mainly caused by cytotoxic effects, or whether immune mechanisms are leading, we used time-lapse imaging to analyse IM-treated warts ex vivo over 24 hours. Ex vivo IM-treated warts, which have been detached from the immune system, did not show destructive necrosis, pointing towards a primarily immune-driven mode of action of IM in the treatment of AGW. PMID- 29461669 TI - Heat Shock Protein Reports on Proteome Stress. AB - Proper regulation of protein homeostasis (proteostasis) is essential to maintain cellular fitness. Proteome stress causes imbalance of the proteostasis, leading to various diseases represented by neurodegenerative diseases, cancers, and metabolic disorders. The biosensor community recently embarked on the development of proteome stress sensors to report on the integrity of proteostasis in live cells. While most of these sensors are based on metastable mutants of specific client proteins, a recent sensor takes advantage of the specific association of heat shock protein 27 with protein aggregates and exhibits a diffusive to punctate fluorescent change in cells that are subjected to stress conditions. Thus, heat shock proteins can be also used as a family of sensors to monitor proteome stress.

PMID- 29461671 TI - Functional characterization of the citrus canker susceptibility gene CsLOB1. AB - Xanthomonas citri ssp. citri (Xcc) is an important plant-pathogenic bacterium that causes citrus canker disease worldwide. PthA, a transcriptional activator like (TAL) effector, directs the expression of the canker susceptibility gene CsLOB1. Here, we report our recent progress in the functional characterization of CsLOB1. Subcellular localization analysis of CsLOB1 protein in citrus protoplast revealed that CsLOB1 is primarily localized in the nucleus. We showed that CsLOB1 expression driven by dexamethasone (DEX) in CsLOB1-GR transgenic plants is associated with pustule formation following treatment with DEX. Pustule formation was not observed in DEX-treated wild-type plants and in non-treated CsLOB1-GR transgenic plants. Water soaking is typically associated with symptoms of citrus canker. Weaker water soaking was observed with pustule formation in CsLOB1-GR transgenic plants following DEX treatment. When CsLOB1-GR-transgenic Duncan grapefruit leaves were inoculated with Xcc306DeltapthA4 and treated with DEX, typical canker symptoms, including hypertrophy, hyperplasia and water soaking symptoms, were observed on DEX-treated transgenic plant leaves, but not on mock treated plants. Twelve citrus genes that are induced by PthA4 are also stimulated by the DEX-induced expression of CsLOB1. As CsLOB1 acts as a transcriptional factor, we identified putative targets of CsLOB1 via bioinformatic and electrophoretic mobility shift assays. Cs2g20600, which encodes a zinc finger C3HC4-type RING finger protein, has been identified to be a direct target of CsLOB1. This study advances our understanding of the function of CsLOB1 and the molecular mechanism of how Xcc causes canker symptoms via CsLOB1.

AB - PURPOSE: To find the potential biomarkers in the diagnostic model of oral and squamous cell carcinoma (OSCC), and to further validate the biomarker. EXPERIMENTAL DESIGN: With the MALDI-TOF-MS analysis between tissues from oral cancer patients and normal oral mucosa from healthy controls, scavenger receptor class A member 5 (scara5) is found to be potentially significant after searching the protein database. In addition, Immunohistochemical staining, PCR, ELISA, and Western blot technique are used to detect scara5 expression in clinical samples and cell lines. RESULTS: In this study, the results indicate that scara5 expression is decreased in tumor group in the MALDI-TOF-MS analysis. Furthermore, down-regulation of scara5 expression is related with cell proliferation and invasion. Serum scara5 detection can discriminate OSCC samples from normal samples with high sensitivity. CONCLUSIONS AND CLINICAL RELEVANCE: Scara5 has the potential to be considered as a serum biomarker in the early diagnosis of OSCC. The clinical relevance of the study lies in finding the biomarker by proteomics and subsequently validating it with clinical samples and cell lines. PMID- 29461674 TI - Risk factors for postoperative intraretinal cystoid changes after peeling of idiopathic epiretinal membranes among patients randomized for balanced salt solution and air-tamponade. AB - PURPOSE: Epiretinal membranes (ERM) are macular disorders leading to loss of vision and metamorphopsia. Vitrectomy with membrane peeling displays the gold standard of care. Aim of this study was to assess risk factors for postoperative intraretinal cystoid changes in a study population randomized for balanced salt solution and air-tamponade at the end of surgery. METHODS: A prospective randomized study, including 69 eyes with idiopathic ERM. Standard 23-gauge three port pars plana vitrectomy with membrane peeling, using intraoperative optical coherence tomography (OCT), was performed. Randomization for BSS and air tamponade was performed prior to surgery. RESULTS: Best-corrected visual acuity improved from 32.9 letters to 45.1 letters 3 months after surgery. Presence of preoperative intraretinal cystoid changes was found to be the only risk factor for presence of postoperative intraretinal cystoid changes 3 months after surgery (p = 0.01; odds ratio: 8.0). Other possible risk factors such as combined phacoemulsification with 23G-ppv and membrane peeling (p = 0.16; odds ratio: 2.4), intraoperative subfoveal hyporeflective zones (p = 0.23; odds ratio: 2.6), age over 70 years (p = 0.29; odds ratio: 0.5) and air-tamponade (p = 0.59; odds ratio: 1.5) were not found to be significant. CONCLUSION: There is strong evidence that preoperative intraretinal cystoid changes lead to smaller benefit from surgery. PMID- 29461675 TI - Improving eye care services with a lean approach. AB - PURPOSE: Effective provision of eye care services in government-financed hospitals is essential to balance the discrepancy between growing demand and limited resources. We aimed to improve efficiency of the treatment protocol for Nd:YAG laser posterior capsulotomy. Predetermined quality targets were a patient oriented and patient-safe approach and the development of a clinical care process with purposeful use of competences. METHODS: We utilized a lean process improvement methodology to develop a streamlined Nd:YAG laser posterior capsulotomy treatment protocol. A total of 206 patient visits were evaluated, where the lean-oriented treatment protocol was utilized in 158 of the visits and the conventional (CONV) protocol was followed in 48 of the visits. RESULTS: All baseline variables were comparable between the study groups. Compared to the CONV protocol, implementation of new operational principles shortened the total reception time per patient from 55:36 +/- 30:23; 12-136 min to 44:40 +/- 4:49; 37 54 min (mean +/- SD; range, p = 0.040). The per hour number of patients and eyes treated in the operation room improved from 4.7 +/- 1.6; 2.6-8.4 patients and 5.5 +/- 2.0; 3.5-11.3 eyes to 16.3 +/- 2.3; 14.3-19.4 patients (p < 0.001) and 18.0 +/- 1.6; 16.8-20.4 eyes (p < 0.001). The time spent by the operating physician reduced from 8:19 +/- 3:06; 3:57-14:30 min to 3:01 +/- 1:00; 1:34-6:38 min in unilateral procedure (p < 0.001) and from 8:45 +/- 3:55; 5:52-14:10 min to 4:40 +/- 2:03; 2:38-10:14 min in bilateral procedure (p < 0.006). Furthermore, the overall patient satisfaction grade improved from 17.3 +/- 1.04; 15-18 points to 17.8 +/- 0.61; 15-18 points (p = 0.001). CONCLUSIONS: The lean approach improved the treatment protocol for Nd:YAG laser posterior capsulotomy with substantial reductions in lead times without compromising patient satisfaction. PMID- 29461676 TI - Clinical and prognostic associations of liver volume determined by computed tomography in acute liver failure. AB - BACKGROUND: Liver volume (LV) can be non-invasively determined from the analysis of computed tomography (CT) images, and in patients with acute liver injury (ALI) or failure (ALF), it can reflect the balance of structural collapse with hepatic regeneration. We examined its relation to cause of liver injury, measures of liver function and histopathological findings, and utility in prediction of complications and mortality. METHODS: Two hundred and seventy-three patients with ALF/ALI admitted to a specialist intensive care unit were studied. One hundred and ninety-nine patients (73%) had non-acetaminophen (NA) aetiologies and 74 (27%) had acetaminophen-induced disease. LV and proportion of predicted LV (PLV%) were determined from admission CT imaging. RESULTS: LV and PLV% showed marked variation when aetiologic groups were compared (P < .0001), including loss in cases with indeterminate cause (LV 939 cm3 [IQR 680-1259], PLV% 56% [42-84]) and increase in Budd-Chiari syndrome (1891 cm3 [1601-2094], 121% [111-131]). Progression to high-grade encephalopathy was more common with smaller LV and PLV. A < 1000 cm3 threshold identified NA patients who later developed it with 93% (95%CI 83-98) specificity and odds ratio 10.6 (3.3-34.5) at median 5 days prior to onset, and risk of death in those with NA-drug-induced (DILI) or indeterminate disease with 91% (71-99) specificity and 63% (50-75) sensitivity. CONCLUSION: In patients with ALF/ALI, LV shows marked variation by the cause of disease, and in prognostic importance. In indeterminate and DILI cases, loss of volume to <1000 cm3 may indicate irreversible liver injury and regenerative failure and serve as an early clinical predictor for the development of high-grade encephalopathy and death. PMID- 29461677 TI - Testicular asymmetry in healthy adolescent boys. AB - OBJECTIVES: To assess the presence of testicular asymmetry and the currently used threshold values in varicocoele management in a healthy adolescent population. SUBJECTS AND METHODS: We conducted an observational cross-sectional study from April 2015 until December 2016 in which we recruited 539 adolescent boys aged 11 16 years. A clinical examination including testicular size measurement by ultrasonography was performed. Testicular volume (TV) was calculated using the Lambert formula (length * width * height * 0.71). The Testicular Atrophy Index (TAI) was calculated using the formula [(TV right - TV left)/largest TV] * 100. The data for all statistical analyses were stratified for Tanner stage for genital development (TSG) and pubic hair (TSP). Non-parametric tests were used to assess the difference between right and left TV, and the prevalence of a smaller left testis for the entire population, and between each TSG and TSP. Parametric tests were used to determine the difference in mean TAI between each TSG and TSP, and to compare the mean TAI to a test value of 0. RESULTS: Of the 539 recruited boys, we excluded 194 due to a current or past pathology, including varicocoeles, influencing normal (testicular) growth or due to incomplete data. Most boys were in the second Tanner stage, followed by the third Tanner stage. The mean (sd) age of the entire population was 13.33 (1.25) years. Of the 345 included participants the mean (sd) left TV was 7.67 (5.63) mL and right TV was 7.97 (5.90) mL. The mean (sd) TAI was 2.85 (17.00)%. In all, 203 (58.84%) boys had a smaller left testis and 142 (41.16%) had a smaller right testis. In all, 51 boys (14.78%) had a TAI >20%, 45 (13.04%) had a TV difference (TVD) of >2 mL with a deficit in left TV, and 69 (20.00)% had a TAI >20% or a TVD of >2 mL with a deficit in left TV. Related-samples Wilcoxon signed-rank test showed a significant difference in mean left and right TV for the entire population, and more specifically for TSG3 (P < 0.001) and TSP3 (P = 0.004). A one-sample t-test showed a significant difference in the mean TAI vs the test value of 0 for the entire population (P = 0.002), and more specifically for TSG3 (P < 0.001) and TSP3 (P = 0.003). CONCLUSION: Testicular asymmetry, with a smaller left testis, was seen in a considerable number of healthy adolescents. One out of five adolescents had a smaller left testis and met one of the threshold values currently used in varicocoele management. Therefore, in left-sided unilateral inguinoscrotal pathology, a smaller ipsilateral testis in combination with a TAI of >20% and/or TVD of >2 mL requires careful interpretation and serial measurements of TV should always be performed. Furthermore, this study provides reference values for TV, TVD and TAI according to TSG and TSP for a healthy adolescent population. PMID- 29461678 TI - The relation between dietary intake and glaucoma: a systematic review. AB - PURPOSE: A common question of patients to their physician is what they can do themselves against glaucoma, except taking their daily medication. However, for ophthalmologists, it is often hard to give their patients an advice on their dietary intake. To help ophthalmologists in answering this question, an overview of the current scientific literature on the association of nutrients with glaucoma is presented. METHODS: A comprehensive systematic review was conducted in which articles published up to September 2017 were identified in PubMed and reference lists. Nutrients were categorized into minerals and trace elements, nutrition with antioxidative properties and omega-fatty acids. RESULTS: The literature search revealed a total of 407 articles of which a total of 46 met the inclusion criteria. Most of these articles studied the effect of nutrients on open-angle glaucoma. Many trace elements have been investigated in the literature, but the most interesting are selenium and iron (both may increase the risk of glaucoma). Investigated nutrients with antioxidative properties and omega fatty acids included glutathione, nitric oxide, carotenoids, flavonoids, and omega-3 and omega-6 fatty acids. Of these, glutathione, nitric oxide, and flavonoids had a significant protective effect on glaucoma. CONCLUSION: Intake of selenium and iron may increase the risk of glaucoma, though, only few studies have been done on this topic. Nitric oxide present in other dark green leafy vegetables seems to have a beneficial effect on glaucoma. However, the evidence for an association of dietary intake with glaucoma is still not strong. More (longitudinal and randomized clinical trials) studies are required to make the presented findings clinically applicable. PMID- 29461680 TI - Reducing-Autophagy Derived Mitochondrial Dysfunction during Resveratrol Promotes Fibroblast-Like Synovial Cell Apoptosis. AB - In rheumatoid arthritis patients, the fibroblast-like synovial cells (FLS) growth is not controlled normally, but is similar to the tumor cells proliferation in histology. Our previous studies have shown that resveratrol inhibits the proliferation of FLS and promotes FLS apoptosis. However, the molecular mechanisms involved in resveratrol-induced FLS apoptosis have not been determined yet. Here, we showed that the FLS cell viability (following pretreatment with 5 uM H2 O2 for 24 hr) exhibited better proliferation performance than at other concentrations via the CCK-8 assay. The cell apoptotic rate increased with the increasing concentration of resveratrol (0, 40, 80, 160, 320 MUM), as detected by TdT-mediated dUTP nick-end labeling (TUNEL) staining and western blotting. Furthermore, the expression level of autophagy-related proteins (LC3A/B, ATG-5) decreased with the increased concentration of resveratrol, as determined by immunofluorescence and western blot analysis. We also showed that resveratrol induced FLS mitochondrial morphology change. Moreover, mitochondrial function detection showed that the mitochondrial membrane potential was lost with the increased concentration of resveratrol as examined by the JC-1 assay. The production of ATP in cells was positively and negatively correlated with the resveratrol concentration. Simultaneously, the intracellular calcium release and calcium influx decreased gradually with the increase in resveratrol concentration. Therefore, we proposed that resveratrol can reduce the level of autophagy in FLS. The decrease in the autophagy level can lead to the accumulation of reactive oxygen species, which may result in mitochondrial dysfunction and promotion of FLS apoptosis. Anat Rec, 2018.

PMID- 29461681 TI - United States Model Midwifery Legislation and Regulation: Development of a Consensus Document. AB - INTRODUCTION: Midwifery is defined and regulated across all 50 United States. However, states' regulations vary markedly, creating confusion for policy makers and consumers, and can limit services to women. In 2011, the International Confederation of Midwives released Global Standards for Midwifery Education, Regulation, and Association, providing guidance for international midwifery for the first time. US organizations representing midwifery education, regulation, and professional associations (US MERA) agreed to work together on common goals. METHODS: The purpose of this modified Delphi study, conducted by US MERA, was to develop a consensus document on principles of model US midwifery legislation and regulation. Expert panelists (N = 51) across maternal and child health care professions and consumer groups participated over several iterative rounds. RESULTS: The final document establishes guiding principles for US midwifery regulation, including regulatory authority, education, qualifications, regulation, registration and licensure, standards of practice and conduct, complaints, and third-party payment for services. DISCUSSION: As more US states recognize and license midwives of all credentials and in every practice setting, we can envision a time when equity, informed choice, safety, and seamless access to quality midwifery care will be the right of every birthing family. PMID- 29461682 TI - Spectacle use after routine cataract surgery and vision-related activity limitation. AB - PURPOSE: To explore the relationship between acquisition of new spectacles after routine cataract surgery and vision-related activity limitation (VRAL) postoperatively. METHODS: This cohort study with intervention (survey) included 1329 patients in Sweden who had undergone a second-eye cataract surgery during March 2013. Data from the Swedish National Cataract Register were used, including evaluations of VRAL through the Catquest-9SF questionnaire before and 3 months after cataract surgery. Five months after the second-eye surgery, patients completed another five-item questionnaire about spectacle use preoperatively and postoperatively including an item on surgeons' advice about the need for spectacles. These responses were linked to the Rasch-analysed Catquest-9SF data to identify correlations with VRAL. RESULTS: A total of 1239 patients finally participated in the study after excluding those who did not fulfil the inclusion criteria. Patients who were advised about the need for spectacles postoperatively (n = 387) had a greater (p = 0.039) improvement in the postoperative VRAL compared to patients who were not advised (n = 691). Patients who obtained new spectacles postoperatively (n = 512) also had greater improvement (p = 0.032) compared to those who did not (n = 724). CONCLUSION: The average improvements in the VRAL after surgery were significantly higher for patients who obtained new distance spectacles postoperatively and for patients who were informed about the need for spectacles by their practitioners. PMID- 29461683 TI - Therapeutic antibiotic serum concentrations by two blood collection methods within the pediatric patient: A comparative effectiveness trial. AB - Repeated venipunctures and fingersticks to confirm serum drug concentrations cause pain and dissatisfaction for pediatric patients and their families. In many organizations, the standard of care to obtain therapeutic serum drug concentrations by peripheral venipuncture or capillary fingerstick, even when the patient has an existing peripheral intravenous catheter (PIV) or central venous catheter (CVC). The primary objective of this study was to assess agreement between serum tobramycin/vancomycin concentrations collected from a CVC or PIV, versus venipuncture or fingerstick. Among hospitalized pediatric patients (age 3 months to 22 years), 36 paired blood samples were collected. Serum trough vancomycin and random tobramycin concentrations were compared between peripheral intravenous or CVC samples, and venipuncture or fingerstick samples within the same patient. A strict sampling protocol for obtaining the samples was followed, that included collection of the CVC/PIV sample before the venipuncture or fingerstick, less than 2 min between collections of samples from the different sites, and a strict volume-based flush and waste protocol. Concordant correlation coefficients demonstrated substantial agreement between CVC/PIV and venipuncture/fingerstick concentrations for vancomycin (n = 17) and tobramycin (n = 19) (Rc = 0.982 for both). Bland-Altman analyses demonstrated good overall between-method agreement within subjects and minimal bias. Consequently, using a lumen volume-based flush and waste protocol, children with indwelling catheters may not require additional venipunctures and/or fingersticks for confirmation of drug concentrations while hospitalized, improving the quality of care and patient satisfaction. PMID- 29461684 TI - How Patterns of Learning About Sexual Information Among Adolescents Are Related to Sexual Behaviors. AB - CONTEXT: Parents, peers and media are informal sources of sexual information for adolescents. Although the content of sexual information communicated by these sources is known to vary, little is known about what adolescents report actually learning from each source. METHODS: Data from 1,990 U.S.14-17-year-olds who participated in an online survey in 2015 were used to assess learning about four topics (sex, condoms, hormonal birth control and romantic relationships) from three informal sources (parents, peers, and television and movies). Gender and race differences in learning by source and topic were assessed using t tests. Following a factor analysis, learning about all topics was grouped by source, and regression analyses were conducted to examine associations between learning from each source and three outcomes: sexual activity, condom use and hormonal birth control use. Models included interactions between information sources and race and gender. RESULTS: White adolescents reported learning more from parents and less from media than black adolescents. Compared with males, females learned more about hormonal birth control and less about condoms from their parents, and more about relationships from peers and media. Learning from parents and from peers were positively associated with adolescents' sexual activity (unstandardized coefficients, 0.26 and 0.52, respectively). Learning from parents was positively associated with condom use (odds ratio, 1.5). CONCLUSION: Adolescents' learning about sex from informal sources varies by race and gender. Future research should examine whether sexual health interventions and message development can capitalize on these differences. PMID- 29461685 TI - Enzymatic Production of Biodiesel: Strategies to Overcome Methanol Inactivation. AB - Lipase-catalyzed transesterification of triglycerides and alcohols to obtain biodiesel is an environmentally friendly and sustainable route for fuels production since, besides proceeding in mild reaction conditions, it allows for the use of low-cost feedstocks that contain water and free fatty acids, for example non-edible oils and waste oils. This review article reports recent advances in the field and focus in particular on a major issue in the enzymatic process, the inactivation of most lipases caused by methanol, the preferred acyl acceptor used for alcoholysis. The recent results about immobilization of enzymes on nano-materials and the use of whole-cell biocatalysts, as well as the use of cell-surface display technologies and metabolic engineering strategies for microbial production of biodiesel are described. It is discussed also insight into the effects of methanol on lipases obtained by modeling approaches and report on studies aimed at mining novel alcohol stable enzymes or at improving robustness in existing ones by protein engineering. PMID- 29461686 TI - ATP-binding cassette subfamily A, member 4 intronic variants c.4773+3A>G and c.5461-10T>C cause Stargardt disease due to defective splicing. AB - PURPOSE: Inherited retinal dystrophies (IRDs) represent a group of progressive conditions affecting the retina. There is a great genetic heterogeneity causing IRDs, and to date, more than 260 genes are associated with IRDs. Stargardt disease, type 1 (STGD1) or macular degeneration with flecks, STGD1 represents a disease with early onset, central visual impairment, frequent appearance of yellowish flecks and mutations in the ATP-binding cassette subfamily A, member 4 (ABCA4) gene. A large number of intronic sequence variants in ABCA4 have been considered pathogenic although their functional effect was seldom demonstrated. In this study, we aimed to reveal how intronic variants present in patients with Stargardt from the same Swedish family affect splicing. METHODS: The splicing of the ABCA4 gene was studied in human embryonic kidney cells, HEK293T, and in human retinal pigment epithelium cells, ARPE-19, using a minigene system containing variants c.4773+3A>G and c.5461-10T>C. RESULTS: We showed that both ABCA4 variants, c.4773+3A>G and c.5461-10T>C, cause aberrant splicing of the ABCA4 minigene resulting in exon skipping. We also demonstrated that splicing of ABCA4 has different outcomes depending on transfected cell type. CONCLUSION: Two intronic variants c.4773+3A>G and c.5461-10T>C, both predicted to affect splicing, are indeed disease-causing mutations due to skipping of exons 33, 34, 39 and 40 of ABCA4 gene. The experimental proof that ABCA4 mutations in STGD patients affect protein function is crucial for their inclusion to future clinical trials; therefore, functional testing of all ABCA4 intronic variants associated with Stargardt disease by minigene technology is desirable. PMID- 29461687 TI - Efficacy of elbasvir and grazoprevir in participants with hepatitis C virus genotype 4 infection: A pooled analysis. AB - BACKGROUND & AIMS: The aim of this integrated analysis was to assess the efficacy of the once-daily combination of elbasvir 50 mg and grazoprevir 100 mg, with and without ribavirin in HCV genotype 4 (GT4)-infected participants enrolled in the Phase 2/3 clinical programme with elbasvir/grazoprevir. METHODS: Treatment-naive and treatment-experienced participants 18 years of age or older with chronic HCV GT4 infection and baseline HCV RNA >=10 000 IU/mL were included in the analysis. The analysis population was the full analysis set (FAS; all participants who received at least 1 dose of study medication) and a total of 155 HCV GT4 participants were evaluated. The primary endpoint was sustained virologic response at week 12 (SVR12; HCV RNA less than the lower limit of quantitation at 12 weeks after the completion of study therapy). RESULTS: Overall, among GT4 infected participants treated with 12 or 16 weeks of elbasvir/grazoprevir +/- ribavirin, the SVR12 efficacy rates were 96.4% (107/111) in treatment-naive participants and 88.6% (39/44) in treatment-experienced participants. The SVR12 rates were 96.0% (97/101) in treatment-naive participants treated with 12 weeks of elbasvir/grazoprevir and 100% (8/8) in treatment-experienced participants treated with 16 weeks of elbasvir/grazoprevir plus ribavirin. Efficacy was not impacted by GT4 subtype. CONCLUSIONS: The regimens of 12 weeks of elbasvir/grazoprevir without ribavirin, and 16 weeks of elbasvir/grazoprevir plus ribavirin, were efficacious in HCV GT4-infected treatment-naive and treatment experienced participants respectively. Baseline NS5A resistance-associated substitutions did not impact the efficacy of elbasvir/grazoprevir in GT4-infected participants. PMID- 29461688 TI - Spontaneous blinking activity in blind patients. PMID- 29461690 TI - Numerical research on the biomechanical behaviour of braided stents with different end shapes and stent-oesophagus interaction. AB - Quasi-static and dynamic numerical analyses are carried out by referring to computational models of commercial self-expandable braided stents with 3 commonly used end shapes, to evaluate the influence of different end shapes of stent on the biomechanical interaction between stent and oesophagus. The end shape has no influence on the equivalent stress, but has a great influence on the contact stress in the narrowest zone of the oesophagus-neoplasm system. However, the end shapes have significant effect on the equivalent stress and the contact stress in the healthy area of the oesophagus in contact with the stent ends. The results show that the maximum equivalent stress of the oesophagus occurs in the zone contact with the cup-shaped end and the maximum contact stress occurs in the zone contact with the edge of the trumpet-shaped stent end. Moreover, the stent apposition is almost not affected by the end shapes. Although small zones with an incomplete stent apposition appear in the transition zones of spherical-cup shaped stent, such occurrence might not contribute to stent malapposition or stent migration. Therefore, these stents with 3 types of end shapes all have good stent apposition. Finally, the numerical simulation results can be used to assess the mechanical performance of stents with different end shapes, the effectiveness of stent expansion therapy, and the possibility of complications after stent implantation. PMID- 29461689 TI - Clinical associations between allergies and rapid eye movement sleep disturbances. AB - BACKGROUND: Allergic rhinitis, an immunoglobulin E inflammatory condition including nasal congestion, obstruction, sneezing, pruritus, and fatigue symptoms, has significant impact on quality of life and impairs sleep. Sleep disordered breathing (SDB) patients often have normal all-night apnea-hypopnea (AHI) or respiratory-disturbance (RDI) indices on polysomnography (PSG). We hypothesized that the rapid eye motion-respiratory disturbance index (REM-RDI) may be a novel predictor of allergic status. METHODS: A retrospective analysis of 100 patients compared REM-RDI results in 67 allergen-positive patients with 33 nonallergic patients who presented with nasal blockage. Subjects completed STOP Bang(c), 22-item Sino-Nasal Outcome Test (SNOT-22)(c), and Epworth Sleepiness Scale(c) questionnaires and underwent skin-prick testing (SPT) and PSGs including REM-RDI values. Using multivariate logistic regression models, we evaluated relationships between allergic status and sleep parameters while controlling for possible confounders including body mass index (BMI). RESULTS: Using REM-RDI as the outcome of interest, allergen-positive patients were 3.92 times more likely to have REM-RDI values in a moderate/severe range (>=15 events/hour); and patients with moderate/severe REM-RDI values were more likely to be allergen positive (p < 0.05). Allergic status was not significantly related to all-night AHI, RDI, or REM-AHI. BMI was not significantly related to REM-RDI. STOP-Bang(c) was related to allergy status (p = 0.02) and REM-RDI (p < 0.01). Allergic patients had increased REM latency and less total amount of REM. CONCLUSION: We revealed significant bidirectional associations between allergen positivity and increased REM-RDI values independent of BMI, AHI, RDI, and REM-AHI. Allergic inflammation and REM-RDI data may play important roles in diagnosing and treating fatigued SDB patients and as objective perioperative safety and outcomes measures.

AB - OBJECTIVE: Individuals with mental illness often live in chronic poverty, which is associated with personal health practices such as tobacco use and poor nutrition that disrupt physical health. The purpose of our study was to examine whether differences exist in personal health and health practices - related to nutrition, physical activity, smoking, alcohol consumption and sleep - between a cohort of individuals with mental illness in southwestern Ontario and the general Canadian population. METHOD: The study sample consisted of 250 individuals who had had a psychiatric diagnosis for at least one year. We conducted a structured quantitative interview with each person to gather information about their personal health and health practices, using question wording from the National Population Health Survey and the Canadian Community Health Survey. We calculated 95% confidence intervals for our results and used them to compare our data with Canadian norms. RESULTS: Individuals with mental illness are significantly more likely than the general population to have a poor diet, experience poor sleep and consume alcohol in excess. CONCLUSION: It is important for nurses, health-care organizations and policy-makers to be aware that a number of factors may be influencing the personal health and health practices of individuals with mental illness and that this population may require different health promotion strategies to support a healthy lifestyle.

AB - BACKGROUND: Globally, about 8.6 million women die each year due to cardiovascular disease with cerebral vascular disease being the third leading cause of death in women. The province of New-foundland and Labrador has one of the highest rates of vascular disease in comparison to the rest of Canada. Women in New-foundland and Labrador have higher rates of vascular disease than their female cohorts across Canada. A vascular risk reduction programfor women aged 35 to 65 years was developed and implemented in a rural and an urban setting. PURPOSE: An evaluation of the program was conducted to assess the impact of the program on participants' satisfaction and to assess how women were able to apply acquired knowledge into their everyday lives to improve their vascular health. PROCEDURE: A thematic analysis of qualitative data collected during tvo focus groups (N=19) was completed. FINDINGS: Three core themes were identified that captured the experiences of the women who participated in the program including Solidifying One's Risk, Translating Knowledge into Action, and Making a Change. IMPLICATIONS: Implementation of community-based vascular education programs must consider the context in which the program is delivered, the population's unique needs, and existing resources if they are to be successful in sustaining healthy lifestyle behaviours known to decrease one's riskfor vascular disease.

AB - Out-of-hospital cardiac arrest (OOHCA) affects 20 to 140 people per 100,000 globally with survival rangingfrom 2% to 11% (Meaney et al., 2013). Patients who have survived, but have been left with cognitive impairments due to anoxic brain injury should be offered early identification and initiation of rehabilitation needs during their admission to mitigate the impact of these deficits (Moulaert et al., 2011). Unfortunately, most cardiac survivors do not receive specialized rehabilitation during their acute hospitalization and there are no clinical pathways that currently exist to guide acute care practitioners regarding the appropriate timing of cognitive screens and early rehabilitation interventions. This tertiary care institution designed and implemented a clinical pathway and patient and family education tools, which have systematically improved the identification and treatment ofpatients requiring cognitive rehabilitation. In this paper, the authors discuss the pathway/tool development and use a case study to highlight these interventions. PMID- 29461711 TI - Risk Factors and Best Practices for the Prevention of Post-Cardiac Surgery Surgical Site Infections in a Tertiary Care Centre. AB - BACKGROUND: Post-cardiac surgery surgical site infections (SSIs) pose devastating consequences in terms of morbidity and mortality to patients. OBJECTIVE: To examine current risk factors and best practice perioperative care for prevention of SSI following cardiac surgery through the lens of the demographic/clinical characteristics of patients who developed post-cardiac surgery SSIs at a major tertiary care institution, and to identify where documentation is lacking and could be improved to better serve clinical practice. METHODS: A literature review on post-cardiac surgery SSI prevention and risk factors was performed. These risk factors were examined through a retrospective chart review of the population of patients who developed SSIs during the study period. RESULTS: The study population was characterized by a high prevalence of riskfactors including age, diabetes, obesity, operative time, blood glucose control, surgical re exploration, blood transfusions, and emergency context, as well as differences from best practice guidelines such as preoperative showering. Compared to other populations in the literature, several ofthese risk factors were more prevalent at the study site than in the other comparable populations. CONCLUSION: The patient population had a relatively high prevalence of riskfactors, and the care received by these patients varied in some ways from best practices. Using best practice guidelines, known risk factors, and the data specific to the institution can provide insightsfor analysis and practice improvement efforts in the form of identifying at-risk patients, improving adherence to best practice guidelines, targeting areas to focus care efforts, and improving clincal documentation. PMID- 29461712 TI - Margaret F. Washburn in The American Journal of Psychology: A Cognitive Precursor? AB - In the early 20th century, Margaret F. Washburn (1871-1939) produced numerous studies on perception, affective value of stimulus, memory, emotions, and consciousness. This experimental work was published in The American Journal of Psychology. The purpose of this article is to analyze the temporal evolution of these kinds of experiments and relate them to Washburn's theoretical production. Contrary to other views, Washburn's experimental evolution follows a logical sequence and has a strong inner coherence. Among other reasons, the lack of a scientific and social framework to the study of the mind has tended to overshadow large areas of Washburn's thought. However, both the work published in AJP and the methods used in experiments provide reasons to consider.Washburn one of the precursors of contemporary cognitive psychology. PMID- 29461713 TI - Edwin G. Boring: The Historian's Path in the Pages of The American Journal of Psychology. AB - Although he is best known for his classic textbook, A History of Experimental Psychology, Edwin Garrigues Boring published dozens of articles in The American Journal of Psychology and used its various formats to guide the discipline in the early 20th century. This report reviews a small sample of his publications, including obituaries, notes, and experimental articles, and presents them in historical and biographical context. A central objective is to show how Boring shared the values of his structuralist training with the emerging American schools and how time allowed him to reconsider his approach to history and the legacy of his iconic mentor, Edward Bradford Titchener. PMID- 29461714 TI - Failures Due to Interruptions or Distractions: A Review and a New Framework. AB - Interruptions of ongoing activities have spread since the development of and global increase in technology use and the general speeding in pace we all experience every day. Their negative effects are well known: decline in performance and emotional distress. However, the literature still needs to shed light on the exact cognitive mechanisms involved in the way users decide to reply to an interruption, on the effects of interruptions of different durations, and on factors influencing reactivation of task schemata and goals at resumption. Therefore, the aim of this article is to review the existing literature and models, uncover unresolved challenges, and propose new ways to confront them. We first review the substantive findings of recent decades from different domains (human-computer interaction, cognitive and experimental psychology, ergonomics), and their respective methodological and theoretical contributions. Then we propose a general and operationalized definition of an interruption; review the different cognitive models of attention, executive control, and working memory that best explain the impact of interruptions; describe current challenges and questions that remain open for future studies; and finally propose an integrative research framework, the DETOUR, which clarifies the cognitive processes at play during interruptions. We believe this work can directly affect the current state of the art, leading to new fundamental studies and applied solutions for the management of interruptions. PMID- 29461715 TI - Modern Speed-Reading Apps Do Not Foster Reading Comprehension. AB - New computer apps are gaining popularity by suggesting that reading speeds can be drastically increased when eye movements that normally occur during reading are eliminated. This is done using rapid serial visual presentation (RSVP), where words are presented 1 at a time, thus preventing natural eye movements such as saccades, fixations, and regressions from occurring. Al- though the companies producing these apps suggest that RSVP reading does not yield comprehension deficits, research investigating the role of eye movements in reading documents shows the necessity of natural eye movements for accurate comprehension. The current study explored variables that may affect reading comprehension during RSVP reading, including text difficulty (6th grade and 12th grade), text presentation speed (static, 700 wpm, and 1,000 wpm), and working memory capacity (WMC). Consistent with recent work showing a tenuous relationship between comprehension and WMC, participants' WMC did not predict comprehension scores. Instead, comprehension was most affected by reading speed: Static text was associated with superior performance, relative to either RSVP reading condition. Furthermore, slower RSVP speeds yielded better verbatim comprehension, and faster speeds benefited inferential comprehension. PMID- 29461716 TI - Parallel Interactive Processing as a Way to Understand Complex Information Processing: The Conjunction Fallacy and Other Examples. AB - Parallel interactive processing (PIP) represents an approach in which specific context generates interactive relationships between general attributes. This article summarizes previous research that demonstrates how such relationships influence inference making in categorization. This is followed by evidence that the approach can be extended to other areas of cognition, including probability judgments. PIP was successful in fitting data that revealed the prevalence of the conjunction fallacy as well as other probability estimation data. PIP provided better fits overall than the signed summation model and the configural weighted average model. The quantum probability model provided good fits for the conjunction fallacy data but not for other probability judgments. PMID- 29461718 TI - The Birth of a New Branch of Medicine: Psychiatry. AB - Psychiatric treatment prior to 1955 seemed to be at a standstill. All kinds of treatments, including surgical ones, were used ineffectively. Then suddenly, out of nowhere, a new treatment -chlorpromazine - created a worldwide revolution. Here is what we saw in Delaware. It was not much different in the rest of the world. Patients improved and were rapidly dischargedfrom mental institutions causing workforce reductions. I was sitting on a state employee job application evaluation committee and witnessed these events. It was also exciting to see rapid changes in administration at the state hospital. Since what happened in Delaware also happened nationally, this was a national event and should be recognized as such. The following few pages are to remember the details. Major changes made psychiatry more of an accepted medical specialty. Psychiatrists are no longer "outsiders." I would be glad to answer any questions about the information presented here. PMID- 29461719 TI - Critical care nursing north of the 6oth Parallel: A qualitative pilot study. AB - BACKGROUND: There is growing knowledge specif c to remote, rural and northern nursing practice in Canada's north. However, there is limited research that specifically addresses the experiences of critical care nurses working in Canada's northern communities. PURPOSE: The purpose of this pilot study was to begin to explore and better understand the experiences of Canadian nurses providing critical care to patients and families in intensive care units north of the 60th parallel. STUDY DESIGN: An interpretive phenomenological analysis was used. METHOD: Telephone interviews were conducted with three registered nurses currently employed in the designated intensive care unit on a full-time, part time or casual basis. Interviews were thematically coded and analyzed. Member checks were used to ensure thick description for this pilot study was obtained. FINDINGS: The following themes evolved through the interpretive phenomenological analysis process, Going North, The Role of the Northern ICU Nurse, Challenges, Support, Positive Aspects of the Experience, and The Northern Experience. CONCLUSIONS: Threaded throughout the main themes, participants made reference to "making it work". Making it work was reflected in how the participants described managing limited resources (particularly human resources), working within an expanded scope and managing the expectation that "the ICU nurse can do it." PMID- 29461720 TI - Changing laws on medical assistance in dying: Implications for critical care nurses. AB - In February 2015, the Supreme Court of Canada released its decision in the Carter v. Canada (Attorney General) case, declaring section 241(b) and section 14 of the Criminal Code invalid, and granting a one-year suspension on that declaration to enable the Parliament of Canada to respond. In June 2016, Bill C-14: An Act to Amend the Criminal Code and Make Related Amendments to Other Acts (Medical Assistance in Dying) was passed after much debate in the House of Commons and Senate of Canada. Brief summaries of the Carter v. Canada case and the new federal law are provided and questions regarding medical assistance in dying are explored. The implications of the case and the new law for critical care nurses are also examined, including the need for nurses to attend to legislative changes, the need for education about the roles of nurses in medical assistance in dying, particularly what can be learned from other jurisdictions, and the importance of understanding the concept of conscientious objection. PMID- 29461717 TI - Targeted Next Generation Sequencing with ThyroSeq v2.1 for Indeterminate Thyroid Nodules in Clinical Practice. AB - OBJECTIVE: To determine if patients elect molecular testing over diagnostic surgery or repeat fine needle aspiration for indeterminate thyroid nodules. Can ThyroSeq v2.1 molecular testing reduce diagnostic thyroid surgery and rule out cancer? STUDY DESIGN: Retrospective review Setting: Single institution, single practice surgeon. SUBJECTS AND METHODS: Fifteen month retrospective review of indeterminate thyroid nodules that went on to ThyroSeq v2.1 testing. RESULTS: 286 patients met American Thyroid Association guideline criteria for surgeon- performed, ultrasound-guided fine needle aspiration for a thyroid nodule with on site cytopathology. The indeterminate (Bethesda III or IV) fine needle aspiration cytology rate was 9.1 percent. Prevalence of malignancy in indeterminate nodules was 19 percent. 26/26 (100 percent) patients with indeterminate thyroid nodules elected molecular testing. 16 patients had no mutation, 9 had one or more mutations, and I had no result. 16 of 25 (64 percent) patients with no mutation elected not to undergo diagnostic surgery for indeterminate thyroid nodules. CONCLUSIONS: Patients demonstrated a strong preference for molecular testing instead of diagnostic thyroid surgery for indeterminate thyroid nodules. All patients in this series, 25/25 (100 percent) with indeterminate thyroid nodules elected molecular testing instead of repeat biopsy or diagnostic thyroid surgery. 16 of 25 (64 percent) patients tested had no mutation. All 16/16 (100 percent) patients with no mutation on ThyroSeq "rule out" testing elected active surveillance rather than surgery or biopsy, reducing diagnostic surgery. The risk of malignancy among mutation negative patients was not definitively established. There are a number of factors currently that may mute the power of "rule in" testing. PMID- 29461721 TI - Intensive care nurses' assessment of pain in patients who are mechanically ventilated: How a pilot study helped to influence practice. AB - BACKGROUND: Pain is a common experience among patients in intensive care units (ICUs). Many patients in ICUs have difficulty communicating their pain because of mechanical ventilation, and issues can arise when the nurse attempts to interpret the severity of pain,and work towards effective pain management. PURPOSE: The aim of this study was to determine the suitability of the Critical-Care Pain Observation Tool (CPOT) as an assessment tool to be used by ICU nursing staff to assess pain in adult. patients who are mechanically ventilated. METHODS: This pilot study was descriptive in design and employed both quantitative and qualitative methods. Quantitative data resulted from the CPOT scores obtained. In addition, a data collection sheet, developed by the authors, recorded sedation and analgesia used and interventions provided. This separate sheet was completed each time the CPOT was used. Nurses were asked to evaluate the CPOT using a Likert scale. Qualitative data were collected through open-ended questions related to using the CPOT Results. Twenty-three participants each assessed pain five times in a total of 23 patients using the CPOT over a 12-hour shift. Nurses stated the tool was easy to use and that it would be helpful to them. CONCLUSION: The results of this pilot study contributed to the decision to implement the CPOT at the study ICUs. The systematic use of a tool may promote more goal-directed management of pain.

For the assessment and the management of face and neck trauma knowledge of the neuro-anatomy and physiology of the ear, nose, throat (ENT) and head and neck (HN) region and structures is essential, as this area is particularly vulnerable to injury. Indeed, the complex anatomy and physiology in this specific area supports important basic functions. In addition, this review elaborates on upper airway and sensorial capacities. Upper airway dimensions are influenced by bony and soft tissues. Age is of fundamental importance in the upper airway assessment, as significant differences in size and proportions apply in children and adults. The cranial nerves (CN) supply motor, sensory ad special sensory fibres to the upper airway. Injury of the CN is a frequent complication of trauma. PMID- 29461731 TI - Emergency care in Belgium.

METHODOLOGY: Literature, Report of The European Observatory on Health Systems, as well as World Health Organization health statistics analysis Results and conclusions: In this chapter, the Belgian healthcare system will be discussed, as well as the area of emergency medicine, which is currently recognized as an independent specialty. The different stakeholders in emergency medicine will also be discussed in this chapter, and their qualifications and responsibilities will be presented. PMID- 29461732 TI - First-line attitudes in acute medicine. AB - First-line attitudes in acute medicine. The often complex problems of the trauma and/or severely ill patient present many challenges to front-line emergency staff. Multiple injuries and/or systems of the body involved require careful and timely prioritization and intervention. Optimum evaluation and resuscitation involves repetitive, systematic ipproaches that are known as the "primary", "secondary" and "tertiary" surveys. The primary survey focuses in general on the ABCDE approach of "Airway, Breathing, Circulation, Disability, Expoure", and is designed to recognize and to treat immediate life-threatening conditions within the initial minutes. This primary resuscitation of non-trauma patients does not differ from the ABCDE approach used to evaluate severely traumatized patients. This approach is applicable in all clinical emergencies, whether the patient is located in the street, at home, in the emergency room, and even in the intensive care or the general wards of the hospital. This approach is widely accepted by experts, and is likely to improve outcomes by helping healthcare professionals to focus on the most life-threatening clinical problems. In an acute setting, high quality ABCDE skills among all treating team members can save valuable time and improve team performance. The secondary and the tertiary surveys are intended to diagnose all injuries before formulating definitive management strategies. This chapter briefly describes how to perform the ABCDE approach in general, and how to conduct the secondary and the tertiary surveys. A more detailed use of this approach within a specific medical condition will be described in later chapters of this report. PMID- 29461733 TI - Pre-hospital interventions: introduction to life support systems. AB - Pre-hospital interventions: introduction to life support systems. Crucial decisions in pre-hospital emergency care are often made; therefore, a tactical emergency medical support team (TEMS) should maintain the capacity to capture the situation instantaneously and in all circumstances. However, low exposure to severe trauma cases can be a weakness for emergency specialists, which makes pre hospital assessment more difficult. Pre-hospital interventions (PHI) are usually classified in Western countries into BLS (basic life support) and ALS (ad- vanced life support) levels, according to the methods used. This review introduces tactical combat casualty care for medical personnel (TCCC) guidelines, designed for basic care management under fire or in a hostile environment. The phases of TCCC are: (1) care under fire (or in an unstable environment); (2) tactical field care; and (3) tactical evacuation care, and are mainly dependent on the different hazard zones (hot, warm or cold). In a mass casualty situation due to disaster or cataclysm, standardized protocol and triage are unquestionably required for identifying the environmental risks, for categorizing the casualties in accordance with medical care priorities, and for the initial management of casualty care. When considering conflict situations, or chemical, biological, radiological, or nuclear (CBRN) events, processes always start at the local level. Even before the detection and analysis of agents can be undertaken, zoning, triage, decontamination, and treatment should be initiated promptly. Otorhinolaryngologists should be aware of PHI procedures for completing preliminary assessment and management together with emergency specialists or TEMS. PMID- 29461734 TI - Protection of respiratory integrity and haemodynamic stabilization. AB - : Protection of respiratory integrity and haemodynamic stabilization. OBJECTIVES: To perform an analysis of the protection of respiratory integrity and haemodynamic stabilization based on the literature review and the experiences and perspectives of emergency and ENT specialists. METHODOLOGY: A comprehensive literature search was undertaken through PubMed and MEDLINE, using the following keywords: [protection of the respiratory integrity], [intubation], [hypotension] and [haemodynamic stabilization]. Articles were selected if the topic was relevant to current ENT and emergency practice. Additional articles were identified through a careful review of reference lists in Uptodate. A critical review of ENT and emergency specialists was carried out. Evidence staging and recommendation levels were established using the Paul Shekelle scale. RESULTS: Firstly, protection of the airway is necessary before starting haemodynamic stabilization. Fibre-optic examination and laryngeal intubation form the gold standard of diagnosis and treatment in the protection of the airway. For circulation, a short catheter with a large size allows the management of intravenous fluids, with vasopressors if necessary. Aetiologic and specific treatments are also very important. CONCLUSIONS: Appropriate and collaborative management is necessary with the "ABCDE" approach: Airway and im- mobilization of the neck; Breathing; Circulation; Disability and Exposure. A fibre-optic examination is the gold standard of airway diagnosis. Laryngeal intubation is the most effective treatment for protection of the respiratory integrity. The management of circulation includes the implementation of a venous route to initiate administration of IVFs, preferably with isotonic saline. Vasopressors and inotropes are used as second line agents. A multidisciplinary and team approach is preferred, in order to achieve diagnosis and therapeutics simultaneously. PMID- 29461735 TI - Facing coagulation disorders after acute trauma. AB - : Facing coagulation disorders after acute trauma. PROBLEMS/OBJECTIVES: Trauma is the leading cause of mortality for persons between one and 44 years of age, essentially due to bleeding complications. METHODOLOGY: We screened the PubMed, Scopus and Cochrane Library databases, using specific keywords. Only publications in English were considered. MAIN RESULTS: The pathophysiology of trauma-induced coagulopathy (TIC) is complex and includes the classic "lethal triad" (i.e., haemodilution, acidosis, hypothermia) but may also include activation of protein C, endothelial and platelet dysfunction, and fibrinogen depletion. The time between trauma and treatment of the resultant massive bleeding should be as short as possible using techniques for rapid control of bleeding and avoiding aggravating factors (hypothermia, metabolic acidosis and hypocalcaemia). If given within three hours of injury, tranexamic acid (TXA) reduces all causes of mortality in trauma patients and reduces transfusion requirements. In a bleeding patient, crystalloids are preferred to colloids and the ratio of fresh frozen plasma to packed red blood cells should be at least 1:2. Damage control surgery (DCS) should be considered for patients who present with, or are at risk for developing, the "lethal triad", multiple life-threatening injuries or shock, and in mass casualty situations. DCS can also aid in the evaluation of the extent of tissue injuries and the control of haemorrhage and infection. Finally, there is currently no evidence of the added value of laboratory assays in the management of TIC. CONCLUSIONS: TIC appears quickly after trauma and should be anticipated and detected as soon as possible. TXA plays a central role in the management of such patients. Each institution should establish a local algorithm for the management of bleeding patients. PMID- 29461736 TI - ENT indications for Hyperbaric Oxygen Therapy. AB - ENT indications for Hyperbaric Oxygen Therapy. Hyperbaric Oxygen (HBO) therapy is a treatment where patients breathe 100% oxygen while exposed to high environmental pressure in a hyperbaric chamber. This hyperoxygenation has several beneficial effects as an adjunctive treatment in a number of ENT-related conditions and diseases. These can be summarized as anti-ischaemic effects (delivery of oxygen to otherwise ischaemic tissues, reduction of ischaemia reperfusion damage), anti-infectious effects (bacteriostasis, improved leucocyte phagocytosis bactericidal activity and optimization of antibiotic therapy) and wound-healing effects (stimulation of granulation tissue formation and stabilization). Since HBO therapy has a clear physiologic rationale, a demonstrated effect (although difficult to "prove" with placebo controlled randomized trials) in certain indications and certain side-effects, it is proposed that it should be considered an integral part of the (combined surgical and pharmacological) treatment of patients, and not simply as a supplementation of oxygen. Furthermore, the importance of a well-trained medical and technical staff to ensure proper selection and the correct follow-up of patients should not be underestimated. PMID- 29461737 TI - Management of burn wounds of the head and neck region. AB - Management of burn wounds of the head and neck region. Management of the severely burned patient is ery often a challenge, not only due to major disturbances in anatomy and physiological processes, but also because the relatively low incidence of this pathology in both civilian and military practice results in care providers'lack of experience. The purpose of this educational document is to provide doctors confronted with these formidable trauma patients with basic management guidelines as well as some practical tips. In summary, and most importantly, these patients should be reated as any other multitrauma patient. First aid is essential and can be provided by non-medical staff. Initial medical nanagement should focus on the usual, familiar trauma algorithms of ABCDEF from the emergency management of evere burns (EMSB) manual' or the ABCDEs of the manual of advanced trauma life support (ATLS)2 or advanced burn life support (ABLS). Medical care should proceed through the following steps - Step one: establish a reliable intravenous nfusion; step two: protect the airway; step three: establish and maintain a haemodynamic state compatible with sufficient organ perfusion in order to reduce aggravation of the burn wounds and increase overall survival likelihood; step four: provide analgesia with adequate sedation and provide anaesthesia for escharotomy, fasciotomy or other surgical injuries; step five: maintain normothermia; step six: feed the patient by starting enteral nutrition as early as possible; step seven: prevent infection using antiseptic wound management, systemic antibiotics and tetanus prophylaxis. All of these intricate steps require continuous reassessment and adjustment, but the existence of other wounds (blast injuries, penetrating and blunt trauma) even further complicates the management of burn casualties. PMID- 29461738 TI - Toxic exposure to caustics and respiratory irritants. AB - Toxic exposure to caustics and respiratory irritants. Toxic emergencies for which the ENT physician is con- sulted mainly involve toxic exposure of the upper airway and digestive tract to caustics and respiratory irritants. The ENT physician may, however, also be involved as a first responder in the case of poisoned patients. This article therefore aims to provide a comprehensive general approach to patients with suspected poisoning and to present a more elaborate discussion on the diagnosis and management of patients following exposure to caustics and respiratory irritants. This survey, however, does not intend to be a substitute for the need for consultation with an emergency physician and a clinical toxicologist qualified in the diagnosis and treatment of poisoned patients. PMID- 29461739 TI - At risk populations: from children to the elderly. AB - : At risk populations:from children to the elderly. PROBLEMS/OBJECTIVES: When considering emergencies in children and elderly people, the risks and consequences are considerably different. For example, the anatomical differences of children have direct consequences on intubation and airway physiology influences breathing, circulation and neurological outcomes.Pharmacotherapy should be adapted for children according to their differences (maturational changes) where drug metabolism and disposition is concerned and for the elderly, to geriatric pharmacokinetics, pharmacodynamics, the existence of poly medications and the risk of adverse drug reactions. METHODOLOGY: Literature review Results: Children respond better to rapid medical care than adults. Hypoxia is dangerous for the child and is responsible for bradycardia and cardiac arrest. Hypoxia can be deleterious for elderly patients because of their fragility, e.g., less metabolic reserves, poor muscular compensation and higher risk of heart failure. CONCLUSIONS: It is widely accepted that children require paediatric-specific assessment/treatment equipment and pharmacotherapy. When compared to adults, there is no difference in the Royal College of Physician guidelines for elderly people's reanimation, however, other criteria such as polypathology, co-morbidity, polypharmacy, fragility, risk of delirium, adverse drug reaction, poor outcome and quality of life should be considered. PMID- 29461740 TI - Acute external ear lesions: clinical aspects, assessment and management. AB - Acute external ear lesions: clinical aspects, assessment and management. We reviewed the literature concerning the assessment and the management of the external ear traumas, which is not very rich. Nevertheless, we outlined the practical attitudes in the four major conditions met: the auricular haematoma, the auricular perichondritis, the auricular laceration and auricular bums. All these pathologies must be promptly treated because there is a risk of perichondritis, which can destroy the cartilage and will result in a severely deformed ear. Auricular haematomas must be drained as soon as possible, lacerations with exposed cartilage must be stitched urgently, and burnt ears should be washed, coated with alginates (Flaminal@) and covered with a loose dressing. Antibioprophyl- axy should always be prescribed after a complete microbiological sampling. PMID- 29461741 TI - Middle ear damages. AB - Middle ear damages. The eardrum and middle ear are often exposed to blunt and penetrating trauma, blasts, thermal or caustic injuries. These injuries may result in tympanic membrane perforation, middle ear haemorrhage, dislocation and fracture of the ossicular chain, perilymphatic fistula and damage to the chorda tympani and/or facial nerve. In case of life-threatening injuries and/or mass casualty incidents, middle ear trauma obviously does not take highest priority. However, middle ear lesions should be suspected and recognized as early as possible. After meticulous history taking, physical examination consists of cranial nerve evaluation, thorough inspection of the outer ear, otoscopy and assessment of hearing and vestibular function. In the majority of cases, traumatic tympanic membrane perforations by penetrating and blunt injuries have a good prognosis with spontaneous resolution. Tympanic membrane perforations from blast trauma, thermal or caustic injuries are less likely to heal spontaneously. Perforations lasting six months after injury warrant surgery. A high resolution CT scan of the temporal bone is required in case of immediate complete facial nerve paralysis and when oval window pathology or perilymphatic fistula is suspected. Early surgical intervention is needed in case of early onset facial nerve paralysis, when there is suspicion of a perilymphatic fistula with persisting or increasing vestibular symptoms or neurosensory hearing loss and in case of vestibular dislocation of the stapes footplate. When ossicular chain damage is suspected, elective tympanoplasty is indicated. As any traumatic tympanic membrane perforation runs the risk of cholesteatoma formation, biannual follow-up during a minimum of two years is recommended. PMID- 29461742 TI - Speech-in-noise testing as a marker for noise-induced hearing loss and tinnitus. AB - Speech-in-noise testing as a marker for noise-induced hearing loss and tinnitus. Noise-induced hearing loss and tinnitus are auditory complaints that often co occur. Often, there is no immediate indication of changes in the pure tone audiogram. Patients can still have clinically normal hearing thresholds while clearly experiencing reduced speech comprehension. This might be explained by the process of neurodegeneration of the innervated dendrites of the auditory nerve fibres and secondary degeneration of spiral ganglion neurons. Subsequent maladaptive neuronal plasticity of the central auditory system can induce tinnitus. Standard hearing testing is no longer sufficient in these patients. Therefore more complex tasks, such as speech-in-noise tests, might be valuable extensions to the standard hearing tests. We carried out a prospective investigation of the influence of tinnitus upon speech comprehension in noise and the effectiveness of speech-in-noise testing, using the Flemish version of the digit triplet test (DTT). Thirty-seven patients with mild noise-induced hearing loss, tinnitus complaints and clinically normal pure tone thresholds completed the DTT and filled in two tinnitus enquiries. A statistically significant (p=0.026) correlation between the averaged high PTA, 2,z and the averaged SRT across ears on the DTT was found. There also seems to be a slight influence of tinnitus onset on the SRT score. PMID- 29461743 TI - Basilar skull fractures: the petrous bone. AB - : Basilar skullfractures: the petrous bone. OBJECTIVES: to provide suggestions for the management of three of the most dangerous or important lesions (internal carotid artery lesions, cerebrospinal fluid leaks and facial nerve paralysis) associated with the petrous part of basilar skull fractures, thereby trying to assess categories of evidence and determine strengths of recommendation. METHODOLOGY: A PubMed-based literature review was carried out, as well as a consultation of online sources as encountered in the literature review. Also, a non-systematic search of chapters of well-known books dealing with the subject of temporal bone traumata was conducted. RESULTS: Specific levels of evidence and/or strength of recommendation can be retrieved from the literature, but only with respect to the prophylactic use of antibiotics, the prescription of antithrombotic medications and the indications for angiography. CONCLUSION: The ample amount of available literature allows for sound management decisions, with reference made to algorithms when available in the literature. Nevertheless, for most of the management/search questions, categories of evidence and strength of recommendation are low or lacking.

PMID- 29461745 TI - The Current Evidence on Retaining or Prosthodontically Replacing Retained Deciduous Teeth in the Adult Hypodontia Patient: A Systematic Review. AB - BACKGROUND: This systematic review aims to evaluate the survival of retaining or replacing deciduous teeth in hypodontia patients with a variety of prosthetic tooth replacement options, to evaluate prognostic factors associated with retaining deciduous teeth, and report on patient based outcomes with these treatment modalities. METHODS: MEDLINE, The Cochrane Central Register of Controlled Trials and Science Direct databases were searched (01/1980 - 08/2017) for studies reporting outcomes associated with retaining or replacing deciduous teeth via prosthetic means in adult hypodontia patients. RESULTS: Twenty-one articles were included. The following survival figures were reported; retaining deciduous tooth/teeth (83%-93%), resin-bonded bridgework (59-96.9%) and implants (86-100%). No survival data was reported for fixed or removable partial dentures. Prognostic factors for deciduous tooth survival, quality of life and patient satisfaction data were also reported. CONCLUSION: Within the limits of this review, retaining deciduous teeth have reasonable survival; however, studies beyond the third decade of life are lacking. Dental implants appear to be a highly successful long-term tooth replacement option with high patient satisfaction within this patient group, as have resin-bonded bridgework, albeit over the short to medium term. Tooth replacement options in the form of fixed and removable partial dentures were poorly reported upon. PMID- 29461747 TI - ?

AB - STATEMENT OF THE PROBLEM: On a pressed lithium disilicate restoration, the building up of a wax pattern of the future restoration is a necessary step on the fabrication process. Conventionally, a wax pattern can be produced by handmade or milled procedures; however, the development of additive manufacturing technologies allows a new fabrication method. PURPOSE: The present study measured the marginal and internal gap of handmade, milled and additive manufactured patterns for an onlay restoration. MATERIAL AND METHODS: A preparation of an onlay restoration was made on an extracted mandibular tooth. A definitive cast was fabricated from a conventional silicone impression of the prepared tooth. Three groups were established: handmade (HM), milled (ML) and additive manufactured (AM); 4 specimens per group were obtained. The marginal and internal gap of each pattern was measured on the extracted molar through a computed tomography test. Sixty measurements were done to measure the marginal gap and another 60 measurements were calculated to analyze the internal gap on each pattern on the prepared tooth. A total of 1.440 measurements were completed. Mann Whitney and Turkey statistical tests were used for pairwise comparison. RESULTS: The mean of the marginal and internal gap was of 67.56 +/- 6.08 MUm and 80.62 +/- 3.26 MUm for the HM group, 85.28 +/- 2.17 MUm and 96 +/- 1.97 MUm for the ML group and 86.49 +/- 1.74 MUm and 91.86 +/- 2.88 MUm for the AM group, respectively. The HM group presented significantly lower marginal (p=0.029) and internal (p=0.029) gap compared to the ML and AM groups. There was no statistical significant difference (p=0.486) on the marginal gap between the ML and the AM groups, but the AM group, showed significantly (p=0.029) smaller internal gap than the ML group. CONCLUSIONS: All the groups presented less than 100 MUm marginal and internal gap, which is a considered clinically acceptable. CLINICAL IMPLICATIONS: The three fabrication processes are viable option for manufacturing patterns for lithium disilicate onlay restorations, but the best marginal and internal fit was still obtained by the conventional handmade procedures.

Depending on the age of the patient, clinical presentation will differ and the origins of the fever vary ; a good awareness of the age-related specificities is essential for early detection of invasive and potentially fatal infections. Fever may also be due to inflammatory diseases. A good knowledge of these aetiologies is essential to avoid unnecessary repeated antibiotic treatments and a lengthy misdiagnosis. PMID- 29461749 TI - [Persistant fevers of infectious origin in children]. AB - Prolonged fevers in children are a regular challenge for the paediatrician or any physician caring for these children (emergency physicians, pediatric infectious diseases specialists). The causes are multiple, classified into three major families : infectious, inflammatory and oncological. Infectious causes are the most common and account for more than 50 % of cases. The objective of this review is to guide physicians in charge of these patients throughout their management by focusing on the quest of infectious causes.

AB - Persistent fever or FUO (fever of unknown origin) is defined by a fever of more than 1-2 weeks that remains unexplained, after considerable diagnostic efforts. In the travelling child, in addition to cosmopolitan infectious diseases, tropical pathogens must absolutely be considered according to the regions visited and the activities practiced. A detailed history and a complete clinical examination are essential to decide which supplementary investigations will complete the basic assessment, which must contain the search for malaria in any child who has visited an endemic area. Following the diagnostic strategy proposed in this article, the clinician should be able to diagnose the most common diseases.

Systemic-onset juvenile idiopathic arthritis and adult-onset Still's disease are both pediatric and respectively adult forms of the disease with a cut-off age of 16 years. The disease is characterized by the following features : hectic fever > 39 degrees C, arthralgia or arthritis, rash, neutrophilia and systemic inflammation. The prognosis of the disease is functional and vital. The evolution over time is variable : regression, evolution by relapses with regression at term and chronic joint evolution. This focus describes the two forms of the disease, their complications and the therapeutic options. PMID- 29461752 TI - [Recurrent auto-inflammatory fevers : a practical diagnostic flow chart]. AB - Recurrent autoinflammatory fever syndromes are characterized by an abnormal activation of the innate immune system pathways, leading to inappropriate systemic inflammation responsible for clinical symptoms. The diagnosis of these conditions is difficult because of their low prevalence, but also because of their nonspecific clinical signs. The presence of clinical inflammatory signs such as fever associated to serositis (arthritis, peritonitis ...) or recurrent cutaneous manifestations and elevated acute phase reactants should help the clinician to make the correct diagnosis. The purpose of this article is to provide a practical management flow chart for children with a suspected autoinflammatory recurrent fever syndrome. PMID- 29461753 TI - [Kawasaki disease: an update]. AB - The cause of Kawasaki disease (KD) is still unknown, but an infectious origin and genetic susceptibility have been suggested. The American Heart Association has changed the guidelines for diagnosis and treatment of KD in 2017. One goal is to better identify patients most at risk, particularly young children with " incomplete " KD. In case of intravenous immunoglobulin resistance, alternative treatments to the traditional use of corticosteroids, such as TNF-alpha inhibitors have been proposed. For all patients with coronary aneurisms, regular assessment of myocardial perfusion is recommended, either with stress echocardiography, MRI, scintigraphy or PET-scan. PMID- 29461754 TI - ?

AB - Despite the economic and environmental services that mangroves provide, they continue to be threatened by overexploitation, pollution, and land use change. Costa Rica has mangrove areas on the Pacific and Caribbean coasts, and cover has been declining since the 1980s. However, data on mangrove coverage are not continually updated and are often based on inaccurate estimates. It is therefore necessary to assess the current extension and variation of the mangrove cover in recent years, to determine changes. The mangrove cover was analyzed in two mangrove forests located in Bahia Culebra, North Pacific: Iguanita and Playa Panama. For this, aerial photographs and satellite imagery were used to study changes for a 65 year period (1945-2010). Spatio-temporal changes were found in mangroves coverage, and adjacent forests and areas without vegetation. Lower mangrove cover occurred during the 1970s (28.4 ha in Iguanita and 4.8 ha in Playa Panama); but increased in recent years (38.9 ha in Iguanita and 12.0 ha in Panama). Changes in forest cover by the Iguanita and Playa Panama mangroves were related to the history of land use around Bahia Culebra. Before 1980, there was extensive and intensive cattle ranching, increasing the deforestation rate; after that year, these practices were abandoned and secondary forest coverage increased until 2000. To ensure the adequate protection of mangroves, it is not only important to protect mangrove forests, but it is also necessary to establish buffer zones on their surroundings, to mitigate and/or reduce possible impacts. PMID- 29461763 TI - Seed dormancy of Ochradenus baccatus (Resedaceae), a shrubby species from Arabian desert regions. AB - Ochradenus baccatus is a perennial glycophyte growing in Middle East and it is one of the most important food sources for many animal species in desert regions. The aim of our study was to investigate the effects of seed storage, light, temperature and gibberellic acid (GA3) on germination of O. baccatus seeds. We also investigated the germination characteristics of O. baccatus seeds under different saline concentration and their capability to recover germination once they were transferred to distilled water. Seeds were stored at room temperature (20 +/- 2 oC) and at -18 oC. Germination tests were conducted at alternating temperatures of 15/25, 20/30 and 25/35 oC in either continuous darkness or photoperiod of 12-h dark/12-h light. To study the effect of GA3 on germination of O. baccatus seeds, freshly-collected seeds and stored seeds were soaked for 24 h in a GA3 water solution (1 g/L) before sowing. To assess the salinity tolerance during germination, seeds were germinated under different salinity levels (100, 200 and 400 mM NaCl). Stored seeds at room temperature and -18 oC germinate equally well at different temperature regimes and light conditions. However, freshly matured seeds were not able to germinate even when they were treated with GA3. On the contrary, stored seeds at room temperature and -18 oC treated with GA3 increase the final germination percentages. These results indicated that O. baccatus seeds have physiological dormancy and they need to be stored in order to break their dormancy. In the present study, one year of storage did not show a significant variation in germination between the two storage conditions assayed. Therefore, further research is needed to know about the maximum storage period for O. baccatus seeds under different storage conditions. Very few O. baccatus seeds (less than 5 %) germinated at the tested lowest concentration of NaCl. However, ungerminated seeds were able to germinate when salinity stress was alleviated. In conclusion, O. baccatus seeds have physiological dormancy, and seed storage (at room temperature and at -18 oC) for one year is effective for breaking this dormancy. In addition, O. baccatus seeds present ability to remain viable in saline conditions and they will be able to germinate once the salinity level decrease.

AB - The spiny lobster Panulirus argus is an important fishery species in the Western Central Atlantic. Changes in the dispersion range through its life cycle and heterogeneous habitats, suggest that P. argus exhibit phenotypic plasticity. However, the morphometric variation of this species is unknown so far, although this information is relevant in evolutionary studies as well as to solve questions of fishery interest. Thus, the aim of this study was to determine whether P. argus exhibit phenotypic variation between sexes, among five geographic origins and three oceanographic conditions of Southwest Caribbean (Colombian archipelago San Andres, Providencia y Santa Catalina). A total of 193 P. argus adults were submitted to geometric morphometrics using six landmarks that delimit one half of the sternal plate. The differences in sternal plate size were compared with Kruskal-Wallis and Mann-Whitney Tests. The allometric effect was estimated using Multivariate Regression Analysis, the model of allometric slopes was tested by Multivariate analysis of covariance and the sternal plate shape differences was explored using non-parametric comparisons of Euclidian distances and Neighbour Joinnig trees. The results showed that the morphometric variation of sternal plate of this spiny lobster varied according to the gender since the sexual size and shape dimorphisms were significant. In both sexes, the sternal plate shape differed among oceanographic scenarios as it was evidenced by significant differences among Euclidian distances, and the tendency to cluster by North, Centre and South sections of San Andres archipelago. Additionally, the morphometric variation resulting from phenotypic plasticity to variable ecological contexts may explain the phenotypic differences among genetically similar populations. This information permits to define management units, support the selection of regulatory policies of this fishery and complement the genetic analysis of the species in this Caribbean region.

AB - The croakers or drums are commercial species, which have been overfished in the Nicoya Gulf, Costa Rica. This study aimed to describe, for the first time, the reproduction and the ontogeny of weakfish, Cynoscion squamipinnis in captivity, in order to perform restocking and mariculture proyects. Wild fish (n= 6, 1-2 Kg) were captured and maintained in the Estacion de Biologia Marina Juan Bertoglia Richards (Puntarenas, Costa Rica) for a two years period (October 2006- December 2008). During this period, maturation stage was monitored periodically by cannula samples in the females (n= 3) and gentle massage in males (n= 3). All fish were stocked in an 18 t tank, with aeration, 33-35 ups of salinity, and a constant temperature (29 +/- 1 degrees C). The spawning period occurred from January to March 2009, producing 162 000 eggs in three spontaneous spawns. The fertilization percentage was 50-60%, and survival after hatching was 60-85%. The egg diameter was 0.852 mm (Standard deviation (SD)= 0.039), and oil drop of 0.269 mm (SD= 0.016). In the embryonary development, the first mitotic division (MD) was observed one hour after spawning (has), the second MD was 1:30 has, the third MD was 2:00 has, the fourth MD was 2:30 has, and fifth MD at 3:00 has. Morule was observed 3:30 has, the blastule 4:30 has, the gastrule 8:30 has, C shape at 10:00 has, and C shape at 12:00 has. After 19 has hatching larvae occurred. The total length (TL) of the larvae was 2.234 mm (SD= 0.122), and the nothochordial length (NL) was 2.179 mm (SD= 0.119). Preflexion stage was observed 49 has, flexion stage was 11 days after spawn (das) (3.767 mm LT (SD= 0.209)), and postflexion stage was 14 das (4.015 mm LT (SD= 0.302)). After 45 das, the juvenile weights 3.68 g (SD= 1.09). Hatch time of the weakfish larvae was minor than of others croaker species. The stages times of embrionary development were a little different from others croaker species, and probably respond to genetic characteristics of each species and the eggs incubation temperature. The spontaneously spawning without broodstock hormonal applications, and the juveniles production in captivity showed that weakfish is a potential species for restocking programs and mariculture projects.

AB - Prosopis ruscifolia is a pioneer tree species in flooding or saline areas. The aim of this work was to assess anatomical changes in roots and hypocotyls of P. ruscifolia seedlings induced to saline stress under controlled conditions. Seeds, collected in natural forests of Western Chaco region in Argentina, were sown on paper towels moisturized with saline solutions of 100, 200 and 300 mM of NaCl, and a control group with distilled water. Four repetitions of 50 seeds per treatment were sown, located in hermetic polystyrene boxes, and included in a seeding chamber, at 27 oC and 12 hours photoperiod. Were studied 35 seedlings from each saline concentration; these seedlings were processed 12 days after sown to obtain microscopic samples. The anatomical variables measured in roots and hypocotyls were the following: main root diameter (um), bark thickness (um), number of cell strata in bark, central cylinder diameter (um), pith diameter (um), number of cell strata in the pericycle and the tangential diameter of vessels (um). ANOVA analysis were performed with hypocotyl and root diameters as the dependent variable, and bark thickness (um), number of cell strata in the bark, the central cylinder diameter (um), the pith diameter (um), number of cell strata in the pericycle, the tangential diameter of vessels and the saline concentration as independent variables. Results showed that the root diameter decreased with increasing saline concentrations (P < 0.0001). The bark thickness decreased at 100 mM (P < 0.0001) and the number of cell strata of bark increased to 300 mM (P < 0.0002). The central cylinder diameter decreased at 100 mM saline concentration (P < 0.0001) and the number of cell strata of the pericycle and the pith diameter reduced progressively until 300 mM. The tangential diameter of vessels decreased at 300 mM. These anatomical changes suggested alterations in the expansion and cell division caused by the salinity, and could limit lateral roots formation and reserves storage. Hypocotyls did not show significant anatomical changes in response to increasing salinity, with exception of stomata position and an increase of the hypodermis thickness. These changes indicated that the water stress imposed by low osmotic potential is caused by increasing saline concentration. The seedlings of P. ruscifolia experienced anatomical changes in response to tested saline concentrations in traits related to reserve storage, the absorption and conduction of water, and lateral roots formation. PMID- 29461767 TI - Scorpions maintenance in captivity for venom extraction purposes in Costa Rica. AB - Approximately 2 000 scorpion species can be found around the world; although few species are considered "harmful" to human beings, a high number of scorpionism cases are reported all over the world. The elaboration of anti-scorpion sera requires the establishment of an animal collection maintained in captivity for venom extraction purposes. The Clodomiro Picado Institute (ICP, for its acronym in Spanish), poses a vast trajectory in manufacturing snakebite antivenoms, and starts a scorpion collection in 2005 for this purpose. In total, 2 043 scorpions were classified in 11 species and collected during a seven-year period using a black-light flashlight and an intensive seeking methodology. The scorpions were collected from several localities of the Pacific and the Caribbean versants of Costa Rica. The venom extraction was performed by applying electrostimulation; the collected venom was characterized by total protein content in addition to median lethal doses. Centruroides bicolor showed higher amounts of venom yield, total protein content and more lethal dose, all of which were correlated with its body mass. The techniques used to keep scorpions in captivity allowed the animals to live several years. Longevity analysis showed significant differences among scorpion genera (H= 353.80; df= 3; P < 0.0001); moreover, the genus Didymocentrus lived longer with an average of 4.46 years. One key factor of its longevity was that it did not go through venom extraction processes. Additionally, a high survival rate of Tityus pachyurus born in captivity, compared to other species within the same genus, was observed (H= 94.32; df= 3; P < 0.0001). This characteristic should be taken into consideration, when programs of reproduction in captivity are designed. In conclusion, the maintenance of a scorpion collection was efficient for venom extraction purposes and a longer life expectancy of the animals. Moreover, there is a scarcity on publications regarding scorpion maintenance in captivity for venom extraction purposes; therefore, a deeper research in aspects such as reproduction, death causes and feeding behaviors is required. PMID- 29461768 TI - Changes in abundance and composition of a Caribbean coral reef zooplankton community after 25 years. AB - Coral reef zooplankton represents a key community in coral ecosystems, as they are involved in trophic and biogeochemical dynamics, and recruitment processes. Zooplankton abundance, composition and biomass were surveyed at six stations within the coral reef at Cahuita National Park, Limon, Costa Rica, in order to compare with the only previous study conducted during 1984. Samples were collected monthly (September 2010-August 2011). Seston biomass (0.49-85.87 mg/m3) and total abundance (1 145-112 422 ind./m3) fluctuated among the months and the stations. Higher values of these two variables were found in the rainiest months (November 2010 and May 2011). A total of 38 taxa were identified, of which calanoid copepods abundance dominated year round (66 %), followed by appendicularians (12 %). Zooplankton mean abundance in this survey resulted 20 times higher (13 184 +/- 4 104 ind./m3)than in 1984 (645 +/- 84 ind./m3). Copepods and appendicularians were the groups that differed the most, relative to the 1984 study, resulting in 63 and 170 times more abundant overall, respectively. An increase in terrestrial runoff and nutrient input during the past 30 years could explain these differences. High abundances of zooplankton may constitute an important food source for coral reef organisms in Cahuita ecosystem. In addition, zooplankton abundances here reported for Cahuita are among the worldwide highest coral reef zooplankton abundances, and further trophic models can help elucidate its role in coral reef resilience in the Caribbean Coast of Central America. PMID- 29461769 TI - Nesting habits of Centris (Hemisiella) dichrootricha (Hymenoptera: Apidae) in the Northern Cerrado of Brazil. AB - The Neotropical bee Centris (Hemisiella) dichrootricha is a solitary bee that nests in pre-existing cavities that occur in the rain forest. This study describes the nesting biology of C. dichrootricha and its preference for nesting in Cerrado and gallery forest habitats. The study was conducted from January 2012 and December 2013, in Mirador State Park in the municipality of Formosa da Serra Negra, Maranhao State, Brazil. For this, wooden trap-nests of 6, 8, 10, 12, 14 and 16 mm in diameter were used; a total of 300 trap-nests were placed in the gallery forest and Cerrado areas, respectively. Traps were monitored monthly and all completed nests were collected and replaced with empty ones. The nests were then taken to the laboratory to analyze bee development and emergence, nests characteristics and parasites presence. The species used 29 of the trap-nests, which had diameters of 8, 10, 12 and 14 mm. A total of 87 C. dichrootricha specimens emerged. The nests were parasitized by two bee species, Mesocheira bicolor (Apinae) and Coelioxys sp. (Megachilinae), and one fly species, Antrax sp. (Diptera). The highest nesting incidence of 72.4 % was observed in the gallery forest, whereas only 27.6 % in the Cerrado; this difference in habitat use was significant (chi2 = 5.56; p < 0.05; DF = 1). For the nests that were built in the gallery forest, 80.9% of the soil originated from the Cerrado. The females were significantly larger than the males (F1, 76 = 595.19; p < 0.001). There were 11 pollen types that belonged to six families. Pollen of the family Malpighiaceae was most frequently used, with four species represented (Byrsonima crassifolia, B. rotunda, B. spicata and Heteropterys sp.). C. dichrootricha showed a preference for nesting in cavities of various diameters in gallery forest sites. The present study provides a novel description of the nesting habits and biology of C. dichrootricha in habitats of Central/Southern Maranhao. C. dichrootricha primarily used resources from the Cerrado, including soil to build their nests, pollen and floral oils; we concluded that gallery forest and Cerrado areas are intrinsically related to the maintenance of local populations of this species. PMID- 29461770 TI - Habitat conditions drive phylogenetic structure of dominant bacterial phyla of microbialite communities from different locations in Mexico. AB - Community structure and composition are dictated by evolutionary and ecological assembly processes which are manifested in signals of, species diversity, species abundance and species relatedness. Analysis of species coexisting relatedness, has received attention as a tool to identify the processes that influence the composition of a community within a particular habitat. In this study, we tested if microbialite genetic composition is dependent on random events versus biological/abiotical factors. This study was based on a large genetic data set of two hypervariable regions (V5 and V6) from previously generated barcoded 16S rRNA amplicons from nine microbialite communities distributed in Northeastern, Central and Southeastern Mexico collected in May and June of 2009. Genetic data of the most abundant phyla (Proteobacteria, Planctomycetes, Verrucomicrobia, Bacteroidetes, and Cyanobacteria) were investigated in order to state the phylogenetic structure of the complete communities as well as each phylum. For the complete dataset, Webb NTI index showed positive and significant values in the nine communities analysed, where values ranged from 31.5 in Pozas Azules I to 57.2 in Bacalar Pirate Channel; meanwhile, NRI index were positive and significant in six of the nine communities analysed with values ranging from 18.1 in Pozas Azules I to 45.1 in Rio Mesquites. On the other hand, when comparing each individual phylum, NTI index were positive and significant in all groups, except in Cyanobacteria for which positive and significant values were only found in three localities; finally, NRI index was significant in only a few of the comparisons performed. The results suggest that habitat filtering is the main process that drives phylogenetic structure in bacterial communities associated to microbialites with the exception of Cyanobacteria where different lineages can contribute to microbialite formation and growth. PMID- 29461783 TI - Relevance of the ancestry for the variability of the Drug-Metabolizing Enzymes CYP2C9, CYP2C19 and CYP2D6 polymorphisms in a multiethnic Costa Rican population. AB - CYP2C9, CYP2C19 and CYP2D6 metabolize around 40% of drugs and their genes vary across populations. The Costa Rican population has a trihybrid ancestry and its key geographic location turns it into a suitable scenario to evaluate interethnic differences across populations. This study aims to describe the diversity of CYP2C9, CYP2C19 and CYP2D6 polymorphisms in Costa Rican populations in the context of their ancestry. A total of 448 healthy individuals were included in the study: Bribri (n= 47), Cabecar (n= 27), Maleku (n= 16), Guaymi (n= 30), Huetar (n= 48), Chorotega (n= 41), Admixed/Mestizos from the Central Valley/Guanacaste (n= 189), and Afro-Caribbeans (n= 50) from Limon. CYP2C9 (alleles *2, *3, *6) and CYP2C19 (*2, *3, *4, *5, *17) genotypes were determined by Real-Time PCR. African, European and Native American ancestry were inferred using 87 ancestry informative markers. The frequency of the decreased activity allele CYP2C9*2 is lower in the self-reported Amerindian groups compared to the admixed population, and the highest frequencies of CYP2C19*2 (null activity) and the CYP2C19*17 (increased activity) were found in the self-reported Afro Caribbean population. Moreover, a frequency of 0.7 % CYP2C9 gPMs in the Admixed population and a variable frequency of CYP2C19 gUMs (0.0-32.6 %, more prevalent in Afro-Caribbeans) in Costa Rican populations, was found. Finally, the following alleles were positively correlated with genomic African ancestry and negatively correlated with genomic Native American ancestry: CYP2D6*5 (null activity), CYP2D6*17 (decreased activity), CYP2D6*29 (decreased activity) and CYP2C19*17 (increased activity). No correlation for CYP2C9 polymorphisms and genomic ancestry was found. Further studies assessing the CYP2C9 and CYP2C19 sequence in these populations, preferentially by sequencing these genes, are warranted.

AB - Coral reefs are under intense conditions of stress caused by the anthropogenic activities in coastalareas and the increase of human population. Water effluents from urban and industrial areas carry large amountsof sediments and pollutants affecting corals populations, inducing bioerosion, increasing diseases and promotingthe development of algae that compete for space with corals. In the Veracruz Reef System National Park(VRSNP) coral reefs are strongly affected by human activities carried out in the area. Gallega and Galleguillareefs are among the most affected by wastewater discharges from the industrial (petrochemical and metallurgical)and urban areas in their vicinity. To assess the potential impact of this contamination on corals inthe VRSNP, a chemical composition and morphology study of 76 Pseudodiploria colonies collected in reefsGallega, Galleguilla, Isla Verde and Isla de Enmedio, was performed. Fragments of ~10 cm2 were collected andboric acid at 0.5 % was used to remove tissue from the skeleton; once clean, the morphology of each samplewas determined with a scanning electron microscope (SEM). Subsequently, to test the chemical composition, anenergy dispersion spectroscopy of X-ray chemical microanalysis (EDSX) was performed in the SEM. We foundthat corals from Gallega and Galleguilla reefs, located closer to human populations, presented high levels oftungsten and the skeleton exhibited multiple perforations. In contrast, corals from the farthest offshore reefs (IslaVerde and Isla de Enmedio) exhibited lower levels of tungsten and fewer perforations in their skeleton. Theseresults demonstrated that anthropogenic activities in the NPVRS are affecting corals skeleton, highly damagingand promoting their bioerosion. The presence of traces of tungsten in the skeleton of corals is an evidence of thedamage that waste discharges are causing to coral reefs. Discharges of large amounts of contaminants promotedthe growth of harmful species that grow and develop into the corals skeleton, causing its bioerosion, and makingthem susceptible to disease and physical damage. This study is the first evidence of the effects of contaminationon these species; therefore, further studies are necessary to determine the impact of pollution on their biologyand survival. PMID- 29461785 TI - Diversity and spatial genetic structure of a natural population of Theobroma speciosum (Malvaceae) in the Brazilian Amazon. AB - The quantification of genetic diversity and intrapopulation spatial genetic structure (SGS) of tree species are important aspects for in and ex situ conservation practices. In this study we seek to understand the importance of conservation areas by quantifying the genetic diversity and the spatial genetic structure of a natural population of Theobroma speciosum. Within this population, 49 adults and 51 subadults were genotyped for five microsatellite loci. The results showed that adults and subadults have similar levels of genetic diversity and inbreeding (adults: A= 10.4, Ae = 10.3, F= 0.68, subadults: A= 10.6, Ae= 10.6, F= 0.57). Genetic diversity was spatially structured within the population, and the results suggest that near-neighbor trees up to a distance of 70 m are likely related. SGS is likely the result of short-distance seed dispersal, the short-distance range of pollinators, and infrequent breaches of the self incompatible mating system. Considering the high demographic density of the species and size of the study area, as well as the high average number of alleles per locus and the presence of rare alleles, we believe that the study population is an excellent resource for in situ genetic conservation of T. speciosum. The study area is also a useful resource for collecting germplasm for ex situ conservation and seed collection, either for breeding programs used in the restoration of degraded areas or forest improvement.

AB - Volatile compounds play a vital role in the life cycle of plants, possessing antimicrobial and anti-herbivore activities, and with a significant importance in the food, cosmetic, chemical, and pharmaceutical industry. This study aimed to identify the volatile compounds emitted by flowers of thirteen species belonging to four genera of Bromeliaceae, using headspace solid-phase micro-extraction and detection by gas chromatography-mass spectrometry. A total of 71 volatile compounds belonging to nine chemical groups were identified. The compounds identified represented more than 97 % of the major components in Aechmea bicolor, Ae. bromeliifolia, Ae. distichantha, Ae. fasciata, and Vriesea friburgensis. In the Ananas varieties, over 99 % of the components were identified, and around 90 % in V. simplex. V. friburgensis presented the largest diversity of volatiles with 31 compounds, while Alcantarea nahoumii presented only 14. All three Ananas varieties presented the same 28 compounds in relatively similar abundance, which has been confirmed by principal component analysis. Current taxonomy and pollination syndrome studies available can adequately explain the variation in volatile compounds among species.

AB - The seed dispersal process is a crucial stage in plant regeneration and maintenance of forest biological diversity. While the number of removed seeds is quantitative, the distance to which a seed is removed from its origin is qualitative, because it affects the probability that a seed will germinate and recruit to the next life stage. However, the creation of forest margins can negatively affect the seed dispersal process, especially for large-diaspore plant species. In this study, the diaspore removal and dispersal distance of Caryocar coriaceum, a tree with large diaspores that is in danger of extinction, were analyzed. The study was conducted for two consecutive years in a protected forest in Northeastern Brazil. Each year, 1 200 diaspores with a nylon wire and a satin tape yellow were used and equally distributed in 120 experimental stations established on the forest margin and in the interior. During the first year of the study, no differences in diaspore removal and dispersal distance were found among the investigated environments. However, for the second year of the study, the number of removed diaspores differed significantly; nevertheless, the dispersal distance was not different between the forest margin and the interior. The low diaspore removal percentages suggest that species recruitment may be compromised because the diaspore accumulation close to the relatives enables higher fungi and insect attack. In addition, most of the few removed diaspores were found at short distances from their sources (up to 5 m), which can lead to low genetic variability. Virtually no diaspore was found buried by hoarding rodents, and no diaspore was found preyed upon by these animals. Evidence found in this study suggests the local loss of species dispersers, which can compromise the maintenance of forest biological diversity.

AB - Local communities in some Asian, African and American countries, use plant toxins in fish poisoning for fishing activities; however, the effects of this practice on the particular wild fish assemblages is unknown. This study was conducted with the aim to investigate the effects of fish poisoning using Tephrosia candida, on freshwater fish diversity and abundance in streams at the boundary of the World Natural Heritage site, Sinharaja Forest Reserve, Sri Lanka. A total of seven field trips were undertaken on a bimonthly basis, from May 2013 to June 2014. We surveyed five streams with similar environmental and climatological conditions at the boundary of Sinharaja forest. We selected three streams with active fish poisoning practices as treatments, and two streams with no fish poisoning as controls. Physico-chemical parameters and flow rate of water in selected streams were also measured at bimonthly intervals. Fish were sampled by electrofishing and nets in three randomly selected confined locations (6 x 2 m stretch) along every stream. Fish species were identified, their abundances were recorded, and Shannon-Weiner diversity index was calculated for each stream. Streams were clustered based on the Bray-Curtis similarity matrix for fish composition and abundance. Physico-chemical parameters of water were not significantly different among streams (P > 0.05). A total of 15 fish species belonging to four different orders Cypriniformes, Cyprinodontiformes, Perciformes and Siluriformes were collected; nine species (60 %) were endemic, and six (40 %) were native species. From these, 13 fish species were recorded in streams with no poisoning, while five species were recorded in streams where poisoning was practiced. Four endemic and one native fish species were locally extinct in streams where fish poisoning was active. Fish abundance was significantly higher in control streams (32-39/m2) when compared to treatment streams (5-9/m2) (P < 0.05). We concluded that fish poisoning with T. candida may have resulted in a significant reduction in species richness, total abundance and Shannon-Weiner diversity index of fish species in the studied streams at the boundary of Sinharaja forest. We recommend that this fishing practice should be strictly regulated, and to inform local communities about the legal status of fish poisoning, its consequences and the importance of fish diversity for local livelihoods and conservation purposes. PMID- 29461789 TI - Biomass allocation and gas exchange are affected by light conditions in endangered Cedrela salvadorensis (Meliaceae) seedlings. AB - The determination of favorable light habitat conditions per species and life stage is transcendental, for both ex situ and in situ conservation strategies of endangered forest tree species, and for their utilization as plantation trees. This becomes especially important when planting material is scarce. We studied the multivariate responses in biomass allocation and in gas exchange to light and to CO2 in Cedrela salvadorensis seedlings, grown under similar light conditions as those this species faces in nature. During a period of 135 days, groups of ten seedlings were put under 75, 45, 15 and 3.5 % of full sun exposure obtained with neutral shade cloth, under nursery conditions. A series of biomass allocation variables and detailed gas exchange parameters (photosynthesis response curves to light and to internal carbon concentration) were measured at the end of the growth period in plants of the four treatments. According to the principal component analyses, highest values of gas exchange response were associated with the lower values of biomass allocation traits. These changes can be associated with resource-conservative and resource-acquisitive strategies, where the C. salvadorensis seedlings acclimatize their traits for the exploration and exploitation of light, to high or to dim light environment, respectively. The multivariate analyses also showed that the plants had a high performance at 45 % of light environment. These results suggest that 45 % of light environment was the optimal light habitat of this species at the tested developing stage. Our results have important implications to choose the best natural habitat for a successful establishment of C. salvadorensis. We propose practical considerations for programs of reforestation or reintroduction where this species be involved. PMID- 29461790 TI - Cranial osteology of the genus Sclerurus (Passeriformes: Furnariidae). AB - The Furnariidae encompasses 293 species and has been recognized as an example of continental adaptive radiation. They inhabit biomes from deserts to humid forests at all strata and show morphological heterogeneity unparalleled among birds at any taxonomic level. Sclerurus is a uniform genus of cryptic, mainly dark brown furnariids, with short black tails which are found solitary on or near the ground inside humid forest. The aim of the present study was to describe and to compare the cranial osteology of all six Sclerurus species (S. scansor, S. mexicanus, S. guatemalensis, S. caudacutus, S. rufigularis, and S. albigularis) to identify osteological characters that are (1) unique to each species, (2) shared among species, and (3) that are exclusive to the genus when compared to other members of Furnariidae. For this, bone structures and measurements were done following standard methodologies. The results showed that Sclerurus differs from other Furnariidae in the following characteristics: a narrowed caudal portion of the nostril with a more rounded shape allowing upper's jaw greater mobility, used when foraging on soft substrates; the development of the post-orbital process may be related to digging behavior, as the presence of a short parsphenoid rostrum projection, a reduced cerebellar prominence, and the tapered caudal portion of the nostrils. Among the species, the interorbital width is larger in S. caudacutus and S. rufigularis, than in the remaining species. The development of the post-orbital process may be related to the behavior of digging nests in earthen banks; the narrowing of the caudal portion of the nostril allows for the greater mobility of the superior maxilla, which is used by Sclerurus when foraging in soft substrates on forest grounds. PMID- 29461791 TI - [Concentrations of alkaloids, cyanogenic glycosides, polyphenols and saponins in selected medicinal plants from Ecuador and their relationship with acute toxicity against Artemia salina]. AB - Alkaloids, polyphenols, cyanogenic glycosides and saponins are among the main chemical compounds synthesized by plants but not considered essential for their basic metabolism. These compounds have different functions in plants, and have been recognized with medicinal and pharmacological properties. In this research, concentrations of the mentioned secondary metabolites were determined in the medicinal plants Artemisia absinthium, Cnidoscolus aconitifolius, Parthenium hysterophorus, Piper carpunya and Taraxacum officinale, from Ecuador, and related with cytotoxic effects against Artemia salina. Alcoholic and aqueous extracts from leaves of these selected plants were prepared at different concentrations. To assess cytotoxicity of these extracts, different bioassays with A. salina were undertaken, and the mortality rates and LC50 were obtained. Besides, concentrations of alkaloids, cyanogenic glycosides, phenols, tannins and saponins were determined by spectrophotometric methods; this constituted the first report of quantification of secondary metabolites in the selected plants from Ecuador. T. officinale had the highest concentration of total phenols (22.30 +/- 0.23 mg/g) and tannins (11.70 +/- 0.10 mg/g), C. aconitifolius of cyanogenic glycosides (5.02 +/- 0.37 ug/g) and P. hysterophorus of saponins (6.12 +/- 0.02 mg/g). Tannins values obtained were not adverse to their consumption. Alcoholic and aqueous extracts of selected plants had hemolytic activity depending on the concentration of saponins. Although the values of cyanogenic glycosides were permissible, it was necessary to monitor the presence of this metabolite in plants to minimize health problems. LC50 values ranged from extremely toxic (3.37 ug/mL) to highly toxic (274.34 MUg/mL), in P. carpunya and T. officinale, respectively. From correlation analysis, it was observed that increase values of alkaloids concentrations had highly significant (p<0.001) acute toxicity against A. salina, while at a higher polyphenol concentration the level of plants cytotoxicity decreased significantly (p<0.001). The results of principal component analysis showed that saponins apparently were in synergy with polyphenols to decrease cytotoxicity, but antagonize with alkaloids and cyanogenic glycosides, indicating that these secondary metabolites present variability in the mechanisms of action against A. salina, as cytotoxic compounds. These results also demonstrate that polyphenols and saponins can be lethal at low concentrations, demonstrating the potential of brine shrimp bioassay as a model to evaluate plant extracts containing low concentrations of chemical compounds with high polarities. The significant positive correlation between cytotoxicity and concentration of alkaloids confirmed by the bioassay of brine shrimp can be useful to identify promising sources of antitumor compounds, and to evaluate tolerable limits not affecting other benign cells. Contents of secondary metabolites found in the selected plants confer them great pharmacologic values.

AB - A novel, simple, and low-cost in situ surface vitrification method has been effectively developed to enhance the optical transparency of rough surface sapphire at UV-visible-IR regions. This method is to obtain a glass layer on the sapphire surface through vitrifaction process. The thickness, refractive index, components and transition temperature of the glass layer have been investigated and discussed respectively by XRD, DSC, SEM and EDS elemental analysis. The experimental results show that the vitrified sapphire has high transparency even after 1000 degrees C annealing at UV-visible-IR regions. PMID- 29461793 TI - Thermally Driven Self-Limiting Atomic Layer Etching of Metallic Tungsten Using WF6 and O2. AB - The semiconductor industry faces a tremendous challenge in the development of a transistor device with sub-10 nm complex features. Self-limiting atomic layer etching (ALE) is essential for enabling the manufacturing of complex transistor structures. In this study, we demonstrated a thermally driven ALE process for tungsten (W) using sequential exposures of O2 and WF6. Based on the insight gained from the previous study on TiO2 thermal ALE, we proposed that etching of W could proceed in two sequential reaction steps at 300 degrees C: (1) oxidation of metallic tungsten using O2 or O3 to form WO3(s) and (2) formation and removal of volatile WO2F2(g) during the reaction between WO3(s) and WF6(g). The O2/WF6 etch process was experimentally studied using a quartz crystal microbalance (QCM). We find that both the O2 and WF6 ALE half reactions are self-limiting, with an estimated steady-state etch rate of ~6.3 A/cycle at 300 degrees C. We also find that etching of W proceeds readily at 300 degrees C, but not at temperatures lower than 275 degrees C. Thermodynamic modeling reveals that the observed temperature dependence is likely due to the limited volatility of WO2F2. The use of WF6 with O3 in place of O2 also allows W etching, where the stronger oxidant leads to a larger mass removal rate per cycle. However, we find O2 to be more controllable for precise metal removal per cycle. In addition, etched W films were examined with ex situ analytical tools. Using spectroscopic ellipsometry (SE) and scanning electron microscopy (SEM), we confirm etching of tungsten film on silicon substrates. Surface analysis by X-ray photoelectron spectroscopy (XPS) revealed a minimal fluorine content on the W film after partial etching and on the silicon surface after full etching. This suggests that W ALE does not significantly alter the chemical composition of W films. This work serves to increase the understanding of ALE reactions and expand the base of available ALE processes for advanced material processing. PMID- 29461794 TI - A New Generation of Surface Active Carbon Textiles As Reactive Adsorbents of Indoor Formaldehyde. AB - Highly porous carbon textiles were modified by impregnation with urea, thiourea, dicyandiamide, or penicillin G, followed by heat treatment at 800 degrees C. This resulted in an incorporation of nitrogen or nitrogen and sulfur heteroatoms in various configurations to the carbon surface. The volume of pores and, especially, ultramicropores was also affected to various extents. The modified textiles were then used as adsorbents of formaldehyde (1 ppmv) in dynamic conditions. The modifications applied significantly improved the adsorptive performance. For the majority of samples, formaldehyde adsorption resulted in a decrease in the volume of ultramicropores. The enhancement in the adsorption was linked not only to the physical adsorption of formaldehyde in small pores but also to its reactivity with sulfonic groups and amines present on the surface. Water on the surface and in challenge gas decreased the adsorptive performance owing to the competition with formaldehyde for polar centers. The results collected show that the S- and N-modified textiles can work as efficient media for indoor formaldehyde removal. PMID- 29461795 TI - Nanoengineered Ionic-Covalent Entanglement (NICE) Bioinks for 3D Bioprinting. AB - We introduce an enhanced nanoengineered ionic-covalent entanglement (NICE) bioink for the fabrication of mechanically stiff and elastomeric 3D biostructures. NICE bioink formulations combine nanocomposite and ionic-covalent entanglement (ICE) strengthening mechanisms to print customizable cell-laden constructs for tissue engineering with high structural fidelity and mechanical stiffness. Nanocomposite and ICE strengthening mechanisms complement each other through synergistic interactions, improving mechanical strength, elasticity, toughness, and flow properties beyond the sum of the effects of either reinforcement technique alone. Herschel-Bulkley flow behavior shields encapsulated cells from excessive shear stresses during extrusion. The encapsulated cells readily proliferate and maintain high cell viability over 120 days within the 3D-printed structure, which is vital for long-term tissue regeneration. A unique aspect of the NICE bioink is its ability to print much taller structures, with higher aspect ratios, than can be achieved with conventional bioinks without requiring secondary supports. We envision that NICE bioinks can be used to bioprint complex, large-scale, cell laden constructs for tissue engineering with high structural fidelity and mechanical stiffness for applications in custom bioprinted scaffolds and tissue engineered implants. PMID- 29461796 TI - More Than a Light Switch: Engineering Unconventional Fluorescent Configurations for Biological Sensing. AB - Fluorescence is a powerful and sensitive tool in biological detection, used widely for cellular imaging and in vitro molecular diagnostics. Over time, three prominent conventions have emerged in the design of fluorescent biosensors: a sensor is ideally specific for its target, only one fluorescence signal turns on or off in response to the target, and each target requires its own sensor and signal combination. These are conventions but not requirements, and sensors that break with one or more of these conventions can offer new capabilities and advantages. Here, we review "unconventional" fluorescent sensor configurations based on fluorescent dyes, proteins, and nanomaterials such as quantum dots and metal nanoclusters. These configurations include multifluorophore Forster resonance energy transfer (FRET) networks, temporal multiplexing, photonic logic, and cross-reactive arrays or "noses". The more complex but carefully engineered biorecognition and fluorescence signaling modalities in unconventional designs are richer in information, afford greater multiplexing capacity, and are potentially better suited to the analysis of complex biological samples, interactions, processes, and diseases. We conclude with a short perspective on the future of unconventional fluorescent sensors and encourage researchers to imagine sensing beyond the metaphorical light bulb and light switch combination. PMID- 29461797 TI - Identification of Protein Targets of 12/15-Lipoxygenase-Derived Lipid Electrophiles in Mouse Peritoneal Macrophages Using Omega-Alkynyl Fatty Acid. AB - The 12/15-lipoxygenase (12/15-LOX) enzyme introduces peroxyl groups, in a position-specific manner, into polyunsaturated fatty acids to form various kinds of bioactive lipid metabolites, including lipid-derived electrophiles (LDE). The resident peritoneal macrophage is the site of highest 12/15-LOX expression in the mouse. However, the role of the enzyme in the regulation of resident macrophages is not fully understood. Here, we describe a chemoproteomic method to identify the targets of enzymatically generated LDE. By treating mouse peritoneal macrophages with omega-alkynyl arachidonic acid (aAA), we identified a series of proteins adducted by LDE generated through a 12/15-LOX catalyzed reaction. Pathway analysis revealed a dramatic enrichment of proteins involved in energy metabolism and found that glycolytic flux and mitochondrial respiration were significantly affected by the expression of 12/15-LOX. Our findings thus highlight the utility of chemoproteomics using aAA for identifying intracellular targets of enzymatically generated LDE. PMID- 29461798 TI - Detection and Identification of Plant Pathogens on Maize Kernels with a Hand-Held Raman Spectrometer. AB - Rapid detection and identification of crop pathogens is essential for improving crop yield. Typical pathogen assaying methods, such as polymerase chain reaction (PCR) or enzyme-linked immunosorbent assay (ELISA), are time-consuming and destructive to the sample. Raman spectroscopy (RS) is a noninvasive nondestructive analytical technique that provides insight on the chemical structure of the specimen. In this study, we demonstrate that using a hand-held Raman spectrometer, in combination with chemometric analyses, we can distinguish between healthy and diseased maize ( Zea mays) kernels, as well as between different diseases with 100% accuracy. Our analysis is portable and sample agnostic, suggesting that it could be retooled for other crops and conducted autonomously. PMID- 29461799 TI - Laser Ablation-Aerosol Mass Spectrometry-Chemical Ionization Mass Spectrometry for Ambient Surface Imaging. AB - Mass spectrometry imaging is becoming an increasingly common analytical technique due to its ability to provide spatially resolved chemical information. Here, we report a novel imaging approach combining laser ablation with two mass spectrometric techniques, aerosol mass spectrometry and chemical ionization mass spectrometry, separately and in parallel. Both mass spectrometric methods provide the fast response, rapid data acquisition, low detection limits, and high resolution peak separation desirable for imaging complex samples. Additionally, the two techniques provide complementary information with aerosol mass spectrometry providing near universal detection of all aerosol molecules and chemical ionization mass spectrometry with a heated inlet providing molecular level detail of both gases and aerosols. The two techniques operate with atmospheric pressure interfaces and require no matrix addition for ionization, allowing for samples to be investigated in their native state under ambient pressure conditions. We demonstrate the ability of laser ablation-aerosol mass spectrometry-chemical ionization mass spectrometry (LA-AMS-CIMS) to create 2D images of both standard compounds and complex mixtures. The results suggest that LA-AMS-CIMS, particularly when combined with advanced data analysis methods, could have broad applications in mass spectrometry imaging applications. PMID- 29461800 TI - Antisense Inhibitors Retain Activity in Pulmonary Models of Burkholderia Infection. AB - The Burkholderia cepacia complex is a group of Gram-negative bacteria that are opportunistic pathogens in immunocompromised individuals, such as those with cystic fibrosis (CF) or chronic granulomatous disease (CGD). Burkholderia are intrinsically resistant to many antibiotics and the lack of antibiotic development necessitates novel therapeutics. Peptide-conjugated phosphorodiamidate morpholino oligomers are antisense molecules that inhibit bacterial mRNA translation. Targeting of PPMOs to the gene acpP, which is essential for membrane synthesis, lead to defects in the membrane and ultimately bactericidal activity. Exploration of additional PPMO sequences identified the ATG and Shine-Dalgarno sites as the most efficacious for targeting acpP. The CF lung is a complex microenvironment, but PPMO inhibition was still efficacious in an artificial model of CF sputum. PPMOs had low toxicity in human CF cells at doses that were antibacterial. PPMOs also reduced the bacterial burden in the lungs of immunocompromised CyBB mice, a model of CGD. Finally, the use of multiple PPMOs was efficacious in inhibiting the growth of both Burkholderia and Pseudomonas in an in vitro model of coinfection. Due to the intrinsic resistance of Burkholderia to traditional antibiotics, PPMOs represent a novel and viable approach to the treatment of Burkholderia infections. PMID- 29461801 TI - Development and Characterization of a Laser-Induced Acoustic Desorption Source. AB - A laser-induced acoustic desorption source, developed for use at central facilities, such as free-electron lasers, is presented. It features prolonged measurement times and a fixed interaction point. A novel sample deposition method using aerosol spraying provides a uniform sample coverage and hence stable signal intensity. Utilizing strong-field ionization as a universal detection scheme, the produced molecular plume is characterized in terms of number density, spatial extend, fragmentation, temporal distribution, translational velocity, and translational temperature. The effect of desorption laser intensity on these plume properties is evaluated. While translational velocity is invariant for different desorption laser intensities, pointing to a nonthermal desorption mechanism, the translational temperature increases significantly and higher fragmentation is observed with increased desorption laser fluence. PMID- 29461802 TI - Ionization of Gas-Phase Polycyclic Aromatic Hydrocarbons in Electrospray Ionization Coupled with Gas Chromatography. AB - Herein, gas-phase polycyclic aromatic hydrocarbons (PAHs) as nonpolar compounds were ionized to protonated molecular ions [M + H]+ without radical cations and simultaneously analyzed using gas chromatography (GC)/electrospray ionization (ESI)-tandem mass spectrometry (MS/MS). The ionization profile, dissociation, and sensitivity were first investigated to understand the significant behavior of gas phase PAHs under ESI. The formation of protonated molecular ions of PAHs was distinguished according to the analyte phase and ESI spray solvents. The protonated PAHs exhibited characteristic dissociations, such as H-loss, H2-loss, and acetylene-loss, via competition of internal energy. In addition, GC/ESI-MS/MS resulted in relatively lower concentration levels (better sensitivity) for the limits-of-detection (LODs) of PAHs than liquid chromatography (LC)/ESI-MS/MS, and it seems to result from the characteristic ionization mechanism of the gas-phase analyte under ESI. Furthermore, the LODs of gas-phase PAHs depended on molecular weight and proton affinity (PA). Consequently, we demonstrated the relationship among the analyte phases, sensitivities, and structural characteristics (molecular weight and PA) under ESI. The gas-phase PAHs provided enhanced protonation efficiency and sensitivity using GC/ESI-MS/MS, as their molecular weight and PA increased. Based on these results, we offered important information regarding the behavior of gas-phase analytes under ESI. Therefore, the present GC/ESI-MS/MS method has potential as an alternative method for simultaneous analysis of PAHs. PMID- 29461803 TI - Exploring Ion Suppression in Mass Spectrometry Imaging of a Heterogeneous Tissue. AB - In this study we have explored several aspects of regional analyte suppression in mass spectrometry imaging (MSI) of a heterogeneous sample, transverse cryosections of mouse brain. Olanzapine was homogeneously coated across the section prior to desorption electrospray ionization (DESI) and matrix-assisted laser desorption ionization (MALDI) mass spectrometry imaging. We employed the concept of a tissue extinction coefficient (TEC) to assess suppression of an analyte on tissue relative to its intensity in an off tissue region. We expanded the use of TEC, by first segmenting anatomical regions using graph-cuts clustering and calculating a TEC for each cluster. The single ion image of the olanzapine [M + H]+ ion was seen to vary considerably across the image, with anatomical features such as the white matter and hippocampus visible. While trends in regional ion suppression were conserved across MSI modalities, significant changes in the magnitude of relative regional suppression effects between techniques were seen. Notably the intensity of olanzapine was less suppressed in DESI than for MALDI. In MALDI MSI, significant differences in the concentration dependence of regional TECs were seen, with the TEC of white matter clusters exhibiting a notably stronger correlation with concentration than for clusters associated with gray matter regions. We further employed cluster specific TECs as regional normalization factors. In comparison to published pixel by-pixel normalization methods, regional TEC normalization exhibited superior reduction ion suppression artifacts. We also considered the usefulness of a segmentation-based approach to compare spectral information obtained from complementary modalities. PMID- 29461804 TI - A Switchable Site-Specific Antibody Conjugate. AB - Genetic incorporation of unnatural amino acids (UAAs) provides a unique approach to the synthesis of site-specific antibody conjugates that are homogeneous and better defined constructs than random conjugates. Yet, the yield varies for every antibody, and the process is costly and time-consuming. We have developed a switchable alphaGCN4-Fab conjugate that incorporates UAA p-acetylphenylalanine. The GCN4 peptide is used as a switch, and antibodies fused by GCN4 can direct the alphaGCN4-Fab conjugate to target different cancer cells for diagnosis, imaging, or therapeutic treatment. More importantly, this switchable conjugate demonstrated an impressive potential for pretargeted imaging in vivo. This approach illustrates the utility of an orthogonal switch as a general strategy to endow versatility to a single antibody conjugate, which should facilitate the application of UAA-based site-specific conjugates for a host of biomedical uses in the future. PMID- 29461805 TI - Autofluorescence-Free Live-Cell Imaging Using Terbium Nanoparticles. AB - Fluorescent nanoparticles (NPs) have become irreplaceable tools for advanced cellular and subcellular imaging. While very bright NPs require excitation with UV or visible light, which can create strong autofluorescence of biological components, NIR-excitable NPs without autofluorescence issues exhibit much lower brightness. Here, we show the application of a new type of surface photosensitized terbium NPs (Tb-NPs) for autofluorescence-free intracellular imaging in live HeLa cells. The combination of exceptionally high brightness, high photostability, and long photoluminecence (PL) lifetimes for highly efficient suppression of the short-lived autofluorescence allowed for time-gated PL imaging of intracellular vesicles over 72 h without toxicity and at extremely low Tb-NP concentrations down to 12 pM. Detection of highly resolved long lifetime (ms) PL decay curves from small (~10 MUm2) areas within single cells within a few seconds emphasized the unprecedented photophysical properties of Tb NPs for live-cell imaging that extend well beyond currently available nanometric imaging agents. PMID- 29461806 TI - White-Light Emission from Layered Halide Perovskites. AB - With nearly 20% of global electricity consumed by lighting, more efficient illumination sources can enable massive energy savings. However, effectively creating the high-quality white light required for indoor illumination remains a challenge. To accurately represent color, the illumination source must provide photons with all the energies visible to our eye. Such a broad emission is difficult to achieve from a single material. In commercial white-light sources, one or more light-emitting diodes, coated by one or more phosphors, yield a combined emission that appears white. However, combining emitters leads to changes in the emission color over time due to the unequal degradation rates of the emitters and efficiency losses due to overlapping absorption and emission energies of the different components. A single material that emits broadband white light (a continuous emission spanning 400-700 nm) would obviate these problems. In 2014, we described broadband white-light emission upon near-UV excitation from three new layered perovskites. To date, nine white-light-emitting perovskites have been reported by us and others, making this a burgeoning field of study. This Account outlines our work on understanding how a bulk material, with no obvious emissive sites, can emit every color of the visible spectrum. Although the initial discoveries were fortuitous, our understanding of the emission mechanism and identification of structural parameters that correlate with the broad emission have now positioned us to design white-light emitters. Layered hybrid halide perovskites feature anionic layers of corner-sharing metal halide octahedra partitioned by organic cations. The narrow, room-temperature photoluminescence of lead-halide perovskites has been studied for several decades, and attributed to the radiative recombination of free excitons (excited electron-hole pairs). We proposed that the broad white emission we observed primarily stems from exciton self-trapping. Here, the exciton couples strongly to the lattice, creating transient elastic lattice distortions that can be viewed as "excited-state defects". These deformations stabilize the exciton affording a broad emission with a large Stokes shift. Although material defects very likely contribute to the emission width, our mechanistic studies suggest that the emission mostly arises from the bulk material. Ultrafast spectroscopic measurements support self-trapping, with new, transient, electronic states appearing upon photoexcitation. Importantly, the broad emission appears common to layered Pb-Br and Pb-Cl perovskites, albeit with a strong temperature dependence. Although the emission is attributed to light-induced defects, it still reflects changes in the crystal structure. We find that greater out-of-plane octahedral tilting increases the propensity for the broad emission, enabling synthetic control over the broad emission. Many of these perovskites have color rendering abilities that exceed commercial requirements and mixing halides affords both "warm" and "cold" white light. The most efficient white-light-emitting perovskite has a quantum efficiency of 9%. Improving this value will make these phosphors attractive for solid-state lighting, particularly as large-area coatings that can be deposited inexpensively. The emission mechanism can also be extended to other low-dimensional systems. We hope this Account aids in expanding the phase space of white-light emitters and controlling their exciton dynamics by the synthetic, spectroscopic, theoretical, and engineering communities. PMID- 29461807 TI - Soft Argon-Propane Dielectric Barrier Discharge Ionization. AB - Dielectric barrier discharges (DBDs) have been used as soft ionization sources (DBDI) for organic mass spectrometry (DBDI-MS) for approximately ten years. Helium-based DBDI is often used because of its good ionization efficiency, low ignition voltage, and homogeneous plasma conditions. Argon needs much higher ignition voltages than helium when the same discharge geometry is used. A filamentary plasma, which is not suitable for soft ionization, may be produced instead of a homogeneous plasma. This difference results in N2, present in helium and argon as an impurity, being Penning-ionized by helium but not by metastable argon atoms. In this study, a mixture of argon and propane (C3H8) was used as an ignition aid to decrease the ignition and working voltages, because propane can be Penning-ionized by argon metastables. This approach leads to homogeneous argon based DBDI. Furthermore, operating DBDI in an open environment assumes that many uncharged analyte molecules do not interact with the reactant ions. To overcome this disadvantage, we present a novel approach, where the analyte is introduced in an enclosed system through the discharge capillary itself. This nonambient DBDI-MS arrangement is presented and characterized and could advance the novel connection of DBDI with analytical separation techniques such as gas chromatography (GC) and high-pressure liquid chromatography (HPLC) in the near future. PMID- 29461808 TI - TiO2-Assisted Laser Desorption/Ionization Mass Spectrometry for Rapid Profiling of Candidate Metabolite Biomarkers from Antimicrobial-Resistant Bacteria. AB - Antimicrobial resistance (AMR) is one of the most serious problems affecting public health and safety. It is crucial to understand antimicrobial resistance from the molecular level. In this work, TiO2-assisted laser desorption/ionization (LDI) mass spectrometry (MS) was used for the fast metabolites analysis from intact bacterial cells to discriminate different strains of bacteria and to detect AMR. With the mass spectra of bacterial metabolites by TiO2-LDI MS, multivariable analysis was performed for bacterial identification to determine distinctive metabolites as the potential biomarkers. The most statistically significant metabolites were screened out by the method and further identified using liquid-chromatography (LC) tandem MS (MS/MS). Robustness of our developed methods in bacterial taxonomy was demonstrated by iterative validation using 48 clinical samples. The strategy was further illustrated with three clinical strains of ESBL (extended-spectrum beta-lactamase-resistant)-positive Escherichia. coli and four clinical strains of ESBL-negative ones. Eleven key metabolites were identified as potential biomarkers of ESBL-positive E. coli. We also implemented the pathway and network analysis on the key metabolites to prove the feasibility of our method in executing metabolomics analysis. Compared to the most prevalent techniques in a metabolomics study, such as LC-MS, gas chromatography MS, and nuclear magnetic resonance spectroscopy, the current method has advantages in its simple sample preparation and short analysis time, thereby fitting especially into clinical usages and fast analyses. PMID- 29461809 TI - Protein-Mediated Shape Control of Silver Nanoparticles. AB - Silver nanoparticles were grown in aqueous solution, without the presence of typical surfactant molecules, but under the presence of different proteins. The shape of the resulting silver nanoparticles could be tuned by the selection of the types of proteins. The amount of accessible lysine groups was found to be mainly responsible for the anisotropy in nanoparticle formation. Viability measurements of cells exposed to protein capped spherical or prism-shaped NPs did not reveal differences between both geometries. Thus, in the case of protein-only coated Ag NPs, no shape-induced toxicity was found under the investigated exposure conditions.

AB - Copper-silver ionization (CSI) is an in-house water disinfection method primarily installed to eradicate Legionella bacteria from drinking water distribution systems (DWDS). Its effect on the abundance of culturable Legionella and Legionella infections has been documented in several studies. However, the effect of CSI on other bacteria in DWDS is largely unknown. To investigate these effects, we characterized drinking water and biofilm communities in a hospital using CSI, in a neighboring building without CSI, and in treated drinking water at the local water treatment plant. We used 16S rDNA amplicon sequencing and Legionella culturing. The sequencing results revealed three distinct water groups: (1) cold-water samples (no CSI), (2) warm-water samples at the research institute (no CSI), and (3) warm-water samples at the hospital (after CSI; ANOSIM, p < 0.001). Differences between the biofilm communities exposed and not exposed to CSI were less clear (ANOSIM, p = 0.022). No Legionella were cultured, but limited numbers of Legionella sequences were recovered from all 25 water samples (0.2-1.4% relative abundance). The clustering pattern indicated local selection of Legionella types (Kruskal-Wallis, p < 0.001). Furthermore, one unclassified Betaproteobacteria OTU was highly enriched in CSI-treated warm water samples at the hospital (Kruskal-Wallis, p < 0.001).

AB - We report the discovery of an eta2-SO2 linkage photoisomer in the osmium pentaammine coordination complex, [Os(NH3)5(SO2)][Os(NH3)5(HSO3)]Cl4 (1). Its dark- and light-induced crystal structures are determined via synchrotron X-ray crystallography, at 100 K, where the photoinduced state is metastable in a single crystal that has been stimulated by 505 nm light for 2.5 h. The SO2 photoisomer in the [Os(NH3)5(SO2)]2+ cation contrasts starkly with the photoinactivity of the HSO3 ligand in its companion [Os(NH3)5(HSO3)]+ cation within the crystallographic asymmetric unit of this single crystal. Panchromatic optical absorption characteristics of this single crystal are revealed in both dark- and light induced states, using concerted absorption spectroscopy and optical microscopy. Its absorption halves across most of its visible spectrum, upon exposure to 505 nm light. The SO2 ligand seems to be responsible for this photoinduced bleaching effect, judging from a comparison of the dark- and light-induced crystal structures of 1. The SO2 photoisomerism is found to be thermally reversible, and so 1 presents a rare example of an osmium-based solid-state optical switch. Such switching in an osmium complex is significant because bottom-row transition metals stand to offer linkage photoisomerism with the greatest photoconversion levels and thermal stability. The demonstration of eta2-SO2 bonding in this complex also represents a fundamental contribution to osmium coordination chemistry.

AB - The chemical contaminants in food and the environment are quite harmful to food safety and human health. Rapid, accurate, and cheap detection can effectively control the potential risks derived from these chemical contaminants. Among all detection methods, the immunoassay based on the specific interaction of antibody analyte is one of the most widely used techniques in the field. However, biological antibodies employed in the immunoassay usually cannot tolerate extreme conditions, resulting in an unstable state in both physical and chemical profiles. Molecularly imprinted polymers (MIPs) are a class of polymers with specific molecular recognition abilities, which are highly robust, showing excellent operational stability under a wide variety of conditions. Recently, MIPs have been used in biomimetic immunoassays for chemical contaminants as an antibody substitute in food and the environment. Here, we reviewed these applications of MIPs incorporated in different analytical platforms, such as enzyme-linked immunosorbent assay, fluorescent immunoassay, chemiluminescent immunoassay, electrochemical immunoassay, microfluidic paper-based immunoassay, and homogeneous immunoassay, and discussed current challenges and future trends in the use of MIPs in biomimetic immunoassays.

AB - A ligand-controlled and site-selective nickel catalyzed Suzuki-Miyaura cross coupling reaction with aromatic esters and alkyl organoboron reagents as coupling partners was developed. This methodology provides a facile route for C(sp2) C(sp3) bond formation in a straightforward fashion by successful suppression of the undesired beta-hydride elimination process. By simply switching the phosphorus ligand, the ester substrates are converted into the alkylated arenes and ketone products, respectively. The utility of this newly developed protocol was demonstrated by its wide substrate scope, broad functional group tolerance and application in the synthesis of key intermediates for the synthesis of bioactive compounds. DFT studies on the oxidative addition step helped rationalizing this intriguing reaction chemoselectivity: whereas nickel complexes with bidentate ligands favor the C(aryl)-C bond cleavage in the oxidative addition step leading to the alkylated product via a decarbonylative process, nickel complexes with monodentate phosphorus ligands favor activation of the C(acyl)-O bond, which later generates the ketone product. PMID- 29461814 TI - Machine Learning of Partial Charges Derived from High-Quality Quantum-Mechanical Calculations. AB - Parametrization of small organic molecules for classical molecular dynamics simulations is not trivial. The vastness of the chemical space makes approaches using building blocks challenging. The most common approach is therefore an individual parametrization of each compound by deriving partial charges from semiempirical or ab initio calculations and inheriting the bonded and van der Waals (Lennard-Jones) parameters from a (bio)molecular force field. The quality of the partial charges generated in this fashion depends on the level of the quantum-chemical calculation as well as on the extraction procedure used. Here, we present a machine learning (ML) based approach for predicting partial charges extracted from density functional theory (DFT) electron densities. The training set was chosen with the goal to provide a broad coverage of the known chemical space of druglike molecules. In addition to the speed of the approach, the partial charges predicted by ML are not dependent on the three-dimensional conformation in contrast to the ones obtained by fitting to the electrostatic potential (ESP). To assess the quality and compatibility with standard force fields, we performed benchmark calculations for the free energy of hydration and liquid properties such as density and heat of vaporization. PMID- 29461815 TI - Mechanistic Insights into the Activation of Soluble Guanylate Cyclase by Carbon Monoxide: A Multistep Mechanism Proposed for the BAY 41-2272 Induced Formation of 5-Coordinate CO-Heme. AB - Soluble guanylate cyclase (sGC) is a heme-containing enzyme that catalyzes cGMP production upon sensing NO. While the CO adduct, sGC-CO, is much less active, the allosteric regulator BAY 41-2272 stimulates the cGMP productivity to the same extent as that of sGC-NO. The stimulatory effect has been thought to be likely associated with Fe-His bond cleavage leading to 5-coordinate CO-heme, but the detailed mechanism remains unresolved. In this study, we examined the mechanism under the condition including BAY 41-2272, 2'-deoxy-3'-GMP and foscarnet. The addition of these effectors caused the original 6-coordinate CO-heme to convert to an end product that was an equimolar mixture of a 5- and a new 6-coordinate CO heme, as assessed by IR spectral measurements. The two types of CO-hemes in the end product were further confirmed by CO dissociation kinetics. Stopped-flow measurements under the condition indicated that the ferrous sGC bound CO as two reversible steps, where the primary step was assigned to the full conversion of the ferrous enzyme to the 6-coordinate CO-heme, and subsequently followed by the slower second step leading a partial conversion of the 6-coordinate CO-heme to the 5-coordinate CO-heme. The observed rates for both steps linearly depended on CO concentrations. The unexpected CO dependence of the rates in the second step supports a multistep mechanism, in which the 5-coordinate CO-heme is led by CO release from a putative bis-carbonyl intermediate that is likely provided by the binding of a second CO to the 6-coordinate CO-heme. This mechanism provides a new aspect on the activation of sGC by CO. PMID- 29461816 TI - Photolytic Reactivity of Organometallic Chromium Bipyridine Complexes. AB - Known stable [Cr(bpy)2(Ph)2](BPh4) complexes undergo reductive elimination of biphenyl with visible-light photolysis using household incandescent or compact fluorescent light bulbs. A series of [Cr(R-bpy)2(Ar)2](X) complexes (R = H or CMe3; Ar = Ph, C6H4-CMe3, or C6H4-OMe; X = I, BPh4, or PF6) were prepared, and the effect of varying the bipyridine and aryl ligands on the UV-visible spectra and electrochemistry of the chromium(III) complexes was investigated. Photolysis of a mixture of two different bis(aryl) complexes gave only the homocoupled biaryl products by 1H NMR and gas chromatography/mass spectrometry analysis. The initial product of photoinduced reductive elimination of [Cr(bpy)2(Ar)2](PF6) was trapped with bipyridine to generate [Cr(bpy)3](PF6) and with benzoyl peroxide to form [Cr(bpy)2(O2CPh)2](PF6). The latter chromium(III) bis(benzoate) complex was also synthesized by the addition of bipyridine and PhCO2H to Cp2Cr, followed by air oxidation. The neutral Cr(bpy)(S2CNMe2)Ph2 complex also generated biphenyl upon visible-light photolysis. While the treatment of Cr(tBu-bpy)(dpm)Cl2 [dpm = (OCtBu)2CH] with AgO2CPh gave trans-Cr(tBu-bpy)(dpm)(O2CPh)2, reaction of the dichloro precursor with PhMgCl produced anionic [Cr(tBu-bpy)Ph3]- with [Mg(dpm)(THF)4]+ as the countercation, with both complexes characterized by single-crystal X-ray diffraction. Protonolysis of Cr(bpy)Ph3(THF) with 8 hydroxyquinoline produced Cr(bpy)(quin)Ph2, which generated biphenyl under visible-light photolysis, and the initial product of reductive elimination was trapped by bipyridine or benzoyl peroxide. A related Cr(bpy)(quin)2 complex was synthesized by protonolysis of Cr(bpy)[N(SiMe3)2]2 and characterized by single crystal X-ray diffraction.

The aromatic counteranions BS, NS, and PS can be used for the tuning of intermolecular coupling through a variety of weak interactions. All of the complexes show temperature-dependent SCO behavior. but the light-induced excited spin-state trapping (LIESST) effect was observed only for 1, 3, and 4 when the samples were illuminated (lambda 808 nm) for 1 h at 5 K. In particular, 59% of the LS form of 1 was converted to the metastable HS state by illumination, equal to the highest degree of conversion yet known for LIESST in [Fe(qsal)2]+ derivatives. The lack of a LIESST effect for 2 may be due to the relatively limited degree of interaction between the cations and anions in the lattice, reflected in a much longer minimum Fe...Fe separation in this complex in comparison to the others.

AB - A novel N-oxygenase-coated core-shell nanoparticle was generated through the coassembly of poly(4-vinylpyridine) (P4VP) and arylamine N-oxygenase CmlI. The resulting enzyme-hybridized particles, P4VP-CmlI, showed excellent catalytic activities on the oxidation of two arylamine substrates, i.e., p-aminophenol ( pAP) and p-aminobenzoic acid ( pABA), using a surrogate redox system or a peroxide shunt as co-oxidants. In comparison with the free enzyme, P4VP-CmlI particles exhibited a significantly enhanced catalytic efficiency when using pyridine nucleotide (NADH) and proper redox mediators. Products at different oxygenation stages were observed. On the contrary, the activity of the enzyme containing nanoparticles was very similar to the free enzyme when using the peroxide shunt. The enhanced catalytic efficiency of the P4VP-CmlI assemblies is attributed to a more efficient electron delivery. PMID- 29461820 TI - Evolution of the Complex Refractive Index of Secondary Organic Aerosols during Atmospheric Aging. AB - The wavelength-dependence of the complex refractive indices (RI) in the visible spectral range of secondary organic aerosols (SOA) are rarely studied, and the evolution of the RI with atmospheric aging is largely unknown. In this study, we applied a novel white light-broadband cavity enhanced spectroscopy to measure the changes in the RI (400-650 nm) of beta-pinene and p-xylene SOA produced and aged in an oxidation flow reactor, simulating daytime aging under NO x-free conditions. It was found that these SOA are not absorbing in the visible range, and that the real part of the RI, n, shows a slight spectral dependence in the visible range. With increased OH exposure, n first increased and then decreased, possibly due to an increase in aerosol density and chemical mean polarizability for SOA produced at low OH exposures, and a decrease in chemical mean polarizability for SOA produced at high OH exposures, respectively. A simple radiative forcing calculation suggests that atmospheric aging can introduce more than 40% uncertainty due to the changes in the RI for aged SOA.

AB - Many indicator displacement assays can detect biological analytes in water, but these often have reduced performance in the presence of an unavoidable component: NaCl. We report here a new self-assembled sensor, DimerDye, that uses a novel photochemical guest-sensing mechanism and that is intrinsically tolerant of cosolutes. We synthetically integrated a dye into a calixarene macrocycle, forming two new merocyanine calixarenes (MCx-1 and MCx-2). Both compounds self assemble into nonemissive dimers in water. The addition of good guests like trimethyllysine induces a turn-on fluorescence response of MCx-1 due to simultaneous dimer dissociation and formation of an emissive host-guest complex. DimerDyes remain functional in solutions containing the various salts, metal ions, and cofactors that are needed for enzymatic reactions. MCx-1 provides a real-time, turn-on fluorescence signal in response to the lysine methyltransferase reaction of PRDM9. PMID- 29461822 TI - Application and Limitations of Nanocasting in Metal-Organic Frameworks. AB - Nanocasting can be a useful strategy to transfer the catalytic metal clusters in metal-organic frameworks (MOFs) to an all-inorganic support such as silica. The incorporation of silica in the MOF pores as a secondary support has the potential to extend the application of the highly tunable metal-based active sites in MOFs to high temperature catalysis. Here, we demonstrate the applicability of the nanocasting method to a range of MOFs that incorporate catalytically attractive hexazirconium, hexacerium, or pentanickel oxide-based clusters (UiO-66, (Ce)UiO 66, (Ce)UiO-67, (Ce)MOF-808, DUT-9, and In- and Ni-postmetalated NU-1000). We describe, in tutorial form, the challenges associated with nanocasting of MOFs that are related to their small pore size and to considerations of chemical and mechanical stability, and we provide approaches to overcome some of these challenges. Some of these nanocast materials feature the site-isolated clusters in a porous, thermally stable silica matrix, suitable for catalysis at high temperatures; in others, structural rearrangement of clusters or partial cluster aggregation occurs, but extensive aggregation can be mitigated by the silica skeleton introduced during nanocasting.

AB - Discovery of the potent antileishmanial effects of antitubercular 6-nitro-2,3 dihydroimidazo[2,1- b][1,3]oxazoles and 7-substituted 2-nitro-5,6 dihydroimidazo[2,1- b][1,3]oxazines stimulated the examination of further scaffolds (e.g., 2-nitro-5,6,7,8-tetrahydroimidazo[2,1- b][1,3]oxazepines), but the results for these seemed less attractive. Following the screening of a 900 compound pretomanid analogue library, several hits with more suitable potency, solubility, and microsomal stability were identified, and the superior efficacy of newly synthesized 6 R enantiomers with phenylpyridine-based side chains was established through head-to-head assessments in a Leishmania donovani mouse model. Two such leads ( R-84 and R-89) displayed promising activity in the more stringent Leishmania infantum hamster model but were unexpectedly found to be potent inhibitors of hERG. An extensive structure-activity relationship investigation pinpointed two compounds ( R-6 and pyridine R-136) with better solubility and pharmacokinetic properties that also provided excellent oral efficacy in the same hamster model (>97% parasite clearance at 25 mg/kg, twice daily) and exhibited minimal hERG inhibition. Additional profiling earmarked R-6 as the favored backup development candidate.

By means of first-principles molecular dynamics simulations, we obtain accurate pair correlation functions of liquid metals, then subtract the mutual information content of these correlations from the ideal gas entropies to predict the absolute entropies over a broad range of temperatures. We apply this method to liquid aluminum and copper and demonstrate good agreement with experimental measurements; then, we apply it to predict the entropy of a liquid aluminum-copper alloy. Corrections due to electronic entropy and many-body correlations are discussed. PMID- 29461827 TI - Current Insights of BRAF Inhibitors in Cancer. AB - Oncogenic BRAF kinase deregulates the ERK signaling pathway in a large number of human tumors. FDA-approved BRAF inhibitors for BRAFV600E/K tumors have provided impressive clinical responses extending survival of melanoma patients. However, these drugs display paradoxical activation in normal tissue with BRAFWT due to RAF transactivation and priming, acquired drug resistance, and limited clinical effectiveness in non-V600 BRAF-dependent tumors, underscoring the urgent need to develop improved BRAF inhibitors. This review provides an overview of recent structural and biochemical insights into the mechanisms of BRAF regulation by BRAF inhibitors that are linked to their clinical activity, clinical liabilities, and medicinal chemistry properties. The effectiveness and challenges of structurally diverse next generation RAF inhibitors currently in preclinical and clinical development are discussed, along with mechanistic insights for developing more effective RAF inhibitors targeting different oncogenic BRAF conformations.

AB - Within current electronic structure theory methods, fully relativistic four component (4c) approaches based on the Dirac Hamiltonian treat spin-orbit coupling with the most rigor. The spin treatment arises naturally from the formulation and does not need to be included ad hoc. Spin-orbit splittings can provide insightful benchmark criteria for the assessment of 4c methods; however, there have not been extensive studies in this respect. Spin-orbit splittings of the p-block elements B-I were computed using the 4c-CASSCF, 4c-CASPT2, and 4c-MR CISD+Q methods, as recently implemented in BAGEL, with uncontracted Dunning basis sets. Comparison with experiment reveals that the four-component methods yield good results, with most of the computed splittings falling within 15% of the experimental values. A large basis set is needed to obtain accurate splittings of the light elements B-F, while splittings of heavier elements show little basis dependence. The 4c-MR-CISD+Q method gave the best splittings for light elements, while 4c-CASSCF showed the best splittings for elements beyond fluorine. The 4c CASPT2 method gave the best splittings for group 13 atoms.

AB - A carefully selected set of acyclic and cyclic model peptides and several other macrocycles, comprising 13 compounds in total, has been used to calibrate the accuracy of the DFT(-D3) method for conformational energies, employing BP86, PBE0, PBE, B3LYP, BLYP, TPSS, TPSSh, M06-2X, B97-D, OLYP, revPBE, M06-L, SCAN, revTPSS, BH-LYP, and omegaB97X-D3 functionals. Both high- and low-energy conformers, 15 or 16 for each compound adding to 196 in total, denoted as the MPCONF196 data set, were included, and the reference values were obtained by the composite protocol, yielding the CCSD(T)/CBS extrapolated energies or their DLPNO CCSD(T)/CBS equivalents in the case of larger systems. The latter was shown to be in near-quantitative (~0.10-0.15 kcal.mol-1) agreement with the canonical CCSD(T), provided the TightPNO setting is used, and, therefore, can be used as the reference for larger systems (likely up to 150-200 atoms) for the problem studied here. At the same time, it was found that many D3-corrected DFT functionals provide results of ~1 kcal.mol-1 accuracy, which we consider as quite encouraging. This result implies that DFT-D3 methods can be, for example, safely used in efficient conformational sampling algorithms. Specifically, the DFT D3/DZVP-DFT level of calculation seems to be the best trade-off between computational cost and accuracy. Based on the calculated data, we have not found any cheaper variant for the treatment of conformational energies, since the semiempirical methods (including DFTB) provide results of inferior accuracy (errors of 3-5 kcal.mol-1).

PMID- 29461831 TI - Spin-Orbit Effects in the Spectroscopy of the X2Pi and a4Sigma- Electronic States of Carbon Iodide, CI. AB - Highly correlated ab initio calculations have been performed to describe the potential energy curves (PECs) and the spectroscopic properties of the X2Pi state and of the first excited state of the CI radical. Multi Reference configuration interaction calculations with Davidson correction (MRCI+Q) and relativistic effective core potential for the iodine atom have been performed. It is found that the two lowest electronic states, the X2Pi and the a4Sigma- states, are stable against dissociation and well separated from the other electronic states. Spectroscopic constants of these two states have been evaluated using their calculated PECs. Because of the presence of the iodine atom in this molecular system, spin-orbit (SO) interactions are playing an important role in the molecular and in the dissociation regions. The excitation energy of the a4Sigma- state is calculated 1.67 eV (MRCI) above the X2Pi ground state and 1.70/1.62 eV (MRCI with SO correction) for the Omega = 1/2 and 3/2 transitions, respectively. The dissociation energy D0 of the X2Pi ground state is evaluated 2.66 eV (MRCI calculation) without SO correction and 2.46/2.36 eV with SO correction for the Omega = 1/2 and 3/2 components, respectively. The dissociation energy D0 of the a4Sigma- state is evaluated 0.99 eV (MRCI calculation) without SO correction and 0.83/0.72 eV with SO correction for the Omega = 1/2 and 3/2 components, respectively. This work should help for the identification of this radical in laboratory and in atmospheric media.

AB - Artificial minielastin constructs have been designed that replicate the structure and function of natural elastins in a simpler context, allowing the NMR observation of structure and dynamics of elastin-like proteins with complete residue-specific resolution. We find that the alanine-rich cross-linking domains of elastin have a partially helical structure, but only when capped by proline rich hydrophobic domains. We also find that the hydrophobic domains, composed of prominent 6-residue repeats VPGVGG and APGVGV found in natural elastins, appear random coil by both NMR chemical shift analysis and circular dichroism. However, these elastin hydrophobic domains exhibit structural bias for a dynamically disordered conformation that is neither helical nor beta sheet with a degree of nonrandom structural bias which is dependent on residue type and position in the sequence. Another nonrandom-coil aspect of hydrophobic domain structure lies in the fact that, in contrast to other intrinsically disordered proteins, these hydrophobic domains retain a relatively condensed conformation whether attached to cross-linking domains or not. Importantly, these domains and the proteins containing them constrict with increasing temperature by up to 30% in volume without becoming more ordered. This property is often observed in nonbiological polymers and suggests that temperature-driven constriction is a new type of protein structural change that is linked to elastin's biological functions of coacervation-driven assembly and elastic recoil.

AB - The apelin receptor generates increasing interest as a potential target across several cardiovascular indications. However, the short half-life of its cognate ligands, the apelin peptides, is a limiting factor for pharmacological use. In this study, we systematically explored each position of apelin-13 to find the best position to cyclize the peptide, with the goal to improve its stability while optimizing its binding affinity and signaling profile. Macrocyclic analogues showed a remarkably higher stability in rat plasma (half-life >3 h versus 24 min for Pyr-apelin-13), accompanied by improved affinity (analogue 15, Ki 0.15 nM and t1/2 6.8 h). Several compounds displayed higher inotropic effects ex vivo in the Langendorff isolated heart model in rats (analogues 13 and 15, maximum response at 0.003 nM versus 0.03 nM of apelin-13). In conclusion, this study provides stable and active compounds to better characterize the pharmacology of the apelinergic system.

AB - Hypoxia-selective cytotoxins (HSCs) seek to exploit the oxygen-poor nature of tumor tissue for therapeutic gain. Typically, HSCs require activation by one electron bioreductive enzymes such as NADPH:cytochrome P450 reductase (CYPOR). Thus, successful clinical deployment of HSCs may be facilitated by the development and implementation of diagnostic probes that detect the presence of relevant bioreductive enzymes in tumor tissue. The work described here develops analogues of the well-studied HSC tirapazamine (3-amino-1,2,4-benzotriazine 1,4 di- N-oxide, TPZ) as profluorescent substrates of the one-electron reductases involved in bioactivation of HSCs. Hypoxic metabolism of TPZ or 7-fluoro-TPZ by one-electron reductases releases inherently fluorescent mono- N-oxide metabolites that may serve as indicators, probes, markers, or stains for the detection of the enzymes involved in the bioactivation of HSCs. In particular, profluorescent compounds of this type can provide a foundation for fluorescence-based bioassays that help identify tumors responsive to HSCs. PMID- 29461835 TI - MS3-IDQ: Utilizing MS3 Spectra beyond Quantification Yields Increased Coverage of the Phosphoproteome in Isobaric Tag Experiments. AB - Protein phosphorylation is critically important for many cellular processes, including progression through the cell cycle, cellular metabolism, and differentiation. Isobaric labeling, for example, tandem mass tags (TMT), in phosphoproteomics workflows enables both relative and absolute quantitation of these phosphorylation events. Traditional TMT workflows identify peptides using fragment ions at the MS2 level and quantify reporter ions at the MS3 level. However, in addition to the TMT reporter ions, MS3 spectra also include fragment ions that can be used to identify peptides. Here we describe using MS3 spectra for both phosphopeptide identification and quantification, a process that we term MS3-IDQ. To maximize quantified phosphopeptides, we optimize several instrument parameters, including the modality of mass analyzer (i.e., ion trap or Orbitrap), MS2 automatic gain control (AGC), and MS3 normalized collision energy (NCE), to achieve the best balance of identified and quantified peptides. Our optimized MS3 IDQ method included the following parameters for the MS3 scan: NCE = 37.5 and AGC target = 1.5 * 105, and scan range = 100-2000. Data from the MS3 scan were complementary to those of the MS2 scan, and the combination of these scans can increase phosphoproteome coverage by >50%, thereby yielding a greater number of quantified and accurately localized phosphopeptides.

AB - Despite the relevance of understanding structure-function relationships, robust prediction of proton donors and nucleophiles in enzyme active sites remains challenging. Here we tested three types of state-of-the-art computational methods to calculate the p Ka's of the buried and hydrogen bonded catalytic dyads in five enzymes. We asked the question what determines the p Ka order, i.e., what makes a residue proton donor vs a nucleophile. The continuous constant pH molecular dynamics simulations captured the experimental p Ka orders and revealed that the negative nucleophile is stabilized by increased hydrogen bonding and solvent exposure as compared to the proton donor. Surprisingly, this simple trend is not apparent from crystal structures and the static structure-based calculations. While the generality of the findings awaits further testing via a larger set of data, they underscore the role of dynamics in bridging enzyme structures and functions.

We suggest a spin-resolved angle-resolved photoemission spectroscopy (ARPES) measurement to detect the unique helical spin texture of the spin-polarized topological surface state, which will provide characteristic evidence for the nontrivial electronic topology of Y2C. Furthermore, the coexistence of 2D surface electride states and topological surface state enables us to explain the outstanding discrepancy between the recent ARPES experiments and theoretical calculations. Our findings establish a preliminary link between the electride in chemistry and the band topology in condensed-matter physics, which are expected to inspire further interdisciplinary research between these fields.

AB - Superionic (SI) phases have utility as solid electrolytes for next generation battery technology, but these phases are typically not stable at room temperature. Our density functional theory calculations demonstrate that compressive lattice strain can stabilize SI phases of Cu2Se and Li2Se, two potential solid electrolytes. Electronic and bonding insights into this effect are obtained. In the ordered, non-SI phase, cations are localized primarily in tetrahedral (T) interstices with little access to the higher-energy octahedral (O) sites, but 1-2% compressive strain promotes attractive stabilization of the O cations with 6-fold coordination to Se anions, at the expense of the stability of 4-fold-coordinated T cations. In such compressed lattices, cations can access both T and O sites, resulting in a cation-disordered, SI phase. Thus, lattice strain is demonstrated as a handle for controlling ionic structure and transport and accomplishing ambient temperature superionicity.

AB - In this paper, we report dispersion-engineered metasurfaces with distinct functionalities controlled by wavelength. Unlike previous approaches based on spatial multiplexing or vertical stacking of metasurfaces, we utilize a single phase profile with wavelength dependence encoded in the phase shifters' dispersion. We designed and fabricated a multiwavelength achromatic metalens (MAM) with achromatic focusing for blue (B), green (G), yellow (Y), and red (R) light and two wavelength-controlled beam generators (WCBG): one focuses light with orbital angular momentum (OAM) states ( l = 0,1,2) corresponding to three primary colors; the other produces ordinary focal spots ( l = 0) for red and green light, while generating a vortex beam ( l = 1) in the blue. A full color (RGB) hologram is also demonstrated in simulation. Our approach opens a path to applications ranging from near-eye displays and holography to compact multiwavelength beam generation.

AB - An enantioselective Cu-catalyzed borylative cross-coupling reaction of alkenes, bis(pinacolato)diboron (B2(pin)2), and methyl iodide is reported. Alkenes including styrenes, beta-substituted styrenes, and challenging aliphatic olefins were smoothly transferred to the desired methylboration products with excellent diastereoselectivities (dr up to >99:1) and enantioselectivities (er up to 99:1). The utility of this process was demonstrated by the synthesis of naproxen and formal synthesis of two natural products.

AB - A novel palladium-catalyzed decarboxylative coupling reaction of vinyl benzoxazinanones with arynes which may feature an intramolecular nucleophilic attack of an amino group at the central carbon of pi-allylpalladium intermediate has been developed. The cis-5,5a,6,10b-tetrahydroindeno[2,1-b]indoles were generated in moderate to good yields. One key to the success of the present reaction was to achieve comparable rates for the palladium-catalyzed decarboxylation and aryne formation steps.

AB - Nonradiative electron-hole recombination plays a key role in determining photon conversion efficiencies in solar cells. Experiments demonstrate significant reduction in the recombination rate upon passivation of methylammonium lead iodide perovskite with Lewis base molecules. Using nonadiabatic molecular dynamics combined with time-domain density functional theory, we find that the nonradiative charge recombination is decelerated by an order of magnitude upon adsorption of the molecules. Thiophene acts by the traditional passivation mechanism, forcing electron density away from the surface. In contrast, pyridine localizes the electron at the surface while leaving it energetically near the conduction band edge. This is because pyridine creates a stronger coordinative bond with a lead atom of the perovskite and has a lower energy unoccupied orbital compared with thiophene due to the more electronegative nitrogen atom relative to thiophene's sulfur. Both molecules reduce two-fold the nonadiabatic coupling and electronic coherence time. A broad range of vibrational modes couple to the electronic subsystem, arising from inorganic and organic components. The simulations reveal the atomistic mechanisms underlying the enhancement of the excited-state lifetime achieved by the perovskite passivation, rationalize the experimental results, and advance our understanding of charge-phonon dynamics in perovskite solar cells.

PMID- 29461844 TI - Microscopic States and the Verwey Transition of Magnetite Nanocrystals Investigated by Nuclear Magnetic Resonance. AB - 57Fe nuclear magnetic resonance (NMR) of magnetite nanocrystals ranging in size from 7 nm to 7 MUm is measured. The line width of the NMR spectra changes drastically around 120 K, showing microscopic evidence of the Verwey transition. In the region above the transition temperature, the line width of the spectrum increases and the spin-spin relaxation time decreases as the nanocrystal size decreases. The line-width broadening indicates the significant deformation of magnetic structure and reduction of charge order compared to bulk crystals, even when the structural distortion is unobservable. The reduction of the spin-spin relaxation time is attributed to the suppressed polaron hopping conductivity in ferromagnetic metals, which is a consequence of the enhanced electron-phonon coupling in the quantum-confinement regime. Our results show that the magnetic distortion occurs in the entire nanocrystal and does not comply with the simple model of the core-shell binary structure with a sharp boundary. PMID- 29461845 TI - Wide Spectral Photoresponse of Layered Platinum Diselenide-Based Photodiodes. AB - Platinum diselenide (PtSe2) is a group-10 transition metal dichalcogenide (TMD) that has unique electronic properties, in particular a semimetal-to-semiconductor transition when going from bulk to monolayer form. We report on vertical hybrid Schottky barrier diodes (SBDs) of two-dimensional (2D) PtSe2 thin films on crystalline n-type silicon. The diodes have been fabricated by transferring large scale layered PtSe2 films, synthesized by thermally assisted conversion of predeposited Pt films at back-end-of-the-line CMOS compatible temperatures, onto SiO2/Si substrates. The diodes exhibit obvious rectifying behavior with a photoresponse under illumination. Spectral response analysis reveals a maximum responsivity of 490 mA/W at photon energies above the Si bandgap and relatively weak responsivity, in the range of 0.1-1.5 mA/W, at photon energies below the Si bandgap. In particular, the photoresponsivity of PtSe2 in infrared allows PtSe2 to be utilized as an absorber of infrared light with tunable sensitivity. The results of our study indicate that PtSe2 is a promising option for the development of infrared absorbers and detectors for optoelectronics applications with low-temperature processing conditions.

AB - A podocarpatriene and a labdatriene derivative, named kujiol A [13-methyl-8,11,13 podocarpatrien-19-ol (1)] and kujigamberol B [15,20-dinor-5,7,9-labdatrien-13-ol (2)], respectively, were isolated from Kuji amber through detection with the aid of their growth-restoring activity against a mutant yeast strain ( zds1Delta erg3Delta pdr1Delta pdr3Delta), which is known to be hypersensitive with respect to Ca2+-signal transduction. The structures were elucidated by spectroscopic data analysis. Compounds 1 and 2 are rare organic compounds from Late Cretaceous amber, and the mutant yeast used seems useful for elucidating a variety of new compounds from Kuji amber specimens, produced before the K-Pg boundary. PMID- 29461848 TI - Leveraging benefit design for better diabetes self-management and A1C control. AB - OBJECTIVES: To evaluate the relationship between cost sharing for blood glucose testing strips and glycemic control rates. STUDY DESIGN: A retrospective observational study using medical and pharmacy claims data integrated with laboratory glycated hemoglobin (A1C) values for patients using insulin and testing strips. A new user study design was utilized to identify individuals from 14 commercial US health plans who filled testing strips with assumed intention to monitor blood glucose. METHODS: Patients were divided into low (<20% of annual testing strip cost; n = 3575) and high (>=20%; n = 3580) cost-sharing categories. We compared the likelihood of patients in low and high cost-sharing categories achieving glycemic control (A1C <8.0%) through modified Poisson regression models. RESULTS: Patients with low cost sharing for testing strips had higher rates of control than those with high cost sharing (58.1% vs 50.3%; P <.001). Low cost sharing was associated with greater probability of glycemic control (adjusted risk ratio [aRR], 1.14; 95% CI, 1.09-1.20; P <.0001). Glycemic control was more likely for patients in areas with median household income greater than $60,000 versus less than $40,000 (aRR, 1.16; 95% CI, 1.07-1.25; P <.01) and greater than $80,000 versus less than $40,000 (aRR, 1.18; 95% CI, 1.06-1.32; P <.01). CONCLUSIONS: We found a statistically significant correlation between cost sharing for testing strips and better A1C control for patients using insulin medication. Lower cost sharing for testing strips can remove a barrier to diabetes self-management and may lead to improved glycemic control at the population level. Future efforts should study the potential benefits of reducing diabetic complications and associated cost savings. PMID- 29461847 TI - Dynamic associations between borderline personality disorder and stressful life events over five years in older adults. AB - The time course of borderline personality disorder (BPD) is far more variable than traditionally assumed. Shifting environmental conditions are theorized to account, at least in part, for fluctuations in symptom presentation over time. In the present study, we evaluated the reciprocal influences of stressful life events and borderline pathology in a representative community sample of 1,630 older adults assessed 3 times over 5 years. An autoregressive cross-lagged model revealed strong, but imperfect, stability in symptoms of BPD over the study time frame. After adjusting for this continuity in BPD, the prospective effect of life stress on borderline pathology was virtually nil, contrary to expectations. On the other hand, borderline pathology was prospectively related to subsequent dependent event (i.e., stressors to which individuals may have contributed), but not independent event (i.e., fateful stressors), exposure. This pattern of associations was consistent with a stress generation effect. We conclude that stressful life events do not substantially redirect the trajectory of BPD in older adults, possibly owing to inertia of borderline pathology at this developmental stage. Instead, symptoms of BPD seem to promote stress exposure, thereby setting the stage for continued social impairment and comorbid psychiatric problems.

AB - OBJECTIVES: To develop and validate a predictive model for first severe chronic obstructive pulmonary disease (COPD) exacerbation using health insurance claims data and to validate the risk measure of controller medication to total COPD treatment (controller and rescue) ratio (CTR). STUDY DESIGN: A predictive model was developed and validated in 2 managed care databases: Truven Health MarketScan database and Reliant Medical Group database. This secondary analysis assessed risk factors, including CTR, during the baseline period (Year 1) to predict risk of severe exacerbation in the at-risk period (Year 2). METHODS: Patients with COPD who were 40 years or older and who had at least 1 COPD medication dispensed during the year following COPD diagnosis were included. Subjects with severe exacerbations in the baseline year were excluded. Risk factors in the baseline period were included as potential predictors in multivariate analysis. Performance was evaluated using C-statistics. RESULTS: The analysis included 223,824 patients. The greatest risk factors for first severe exacerbation were advanced age, chronic oxygen therapy usage, COPD diagnosis type, dispensing of 4 or more canisters of rescue medication, and having 2 or more moderate exacerbations. A CTR of 0.3 or greater was associated with a 14% lower risk of severe exacerbation. The model performed well with C-statistics, ranging from 0.711 to 0.714. CONCLUSIONS: This claims-based risk model can predict the likelihood of first severe COPD exacerbation. The CTR could also potentially be used to target populations at greatest risk for severe exacerbations. This could be relevant for providers and payers in approaches to prevent severe exacerbations and reduce costs. PMID- 29461850 TI - Development of a tailored survey to evaluate a patient-centered initiative. AB - OBJECTIVES: Patient-centered care initiatives have proliferated, but assessing their effectiveness requires measures tailored to their likely effects. In this article, we describe the development and pilot testing of patient surveys used to assess change in patients' cancer care experiences over time in response to a patient-centered care initiative. STUDY DESIGN: Prospective case series. METHODS: Domains of patient-centered care were informed by the goals of the initiative and a review of existing tools. Items were selected and modified from 6 domains of validated or semivalidated instruments. Items were piloted with patients with cancer in waiting room settings to further assess the relevance and clarity of items, whether important concepts were missing, and acceptability regarding place and timing of the surveys and to estimate baseline top box scores (percentage of patients scoring an item the highest quality level) to minimize likely ceiling effects. The instrument was then administered to a consecutive sample of Stanford Cancer Center patients. Baseline item responses, Cronbach's alpha, and response bias were estimated. RESULTS: Items were modified based on patient feedback, top box scores, and reassessment of the domains. Over 6 months, 11,273 patients were surveyed, with a 49.7% response rate. Baseline top box scores ranged from 41.7% to 75.0% for any given item. Reliability and internal consistency were high for all domains (Cronbach's alpha >=0.80) except for the access domain. CONCLUSIONS: We developed reliable instruments to evaluate the essential elements of a patient centered care initiative at an academic medical center, which minimized patient burden and maximized the response rate. PMID- 29461851 TI - Impact of telephonic comprehensive medication reviews on patient outcomes. AB - OBJECTIVES: The majority of studies on medication therapy management (MTM) have focused on the conduct of in-person comprehensive medication reviews (CMRs). Although face-to-face MTM services may be the most well-known mode of delivery, there are other ways CMRs can be implemented as part of an MTM service. Specifically, telephonic CMR is an alternative method of offering MTM services that many patients may welcome. The purpose of this commentary was to highlight current findings regarding the impact of telephonic CMRs as a component of MTM services on health outcomes. STUDY DESIGN: Review of available literature analyzing the impact of telephonic CMRs on health outcomes. METHODS: PubMed was used to identify studies published between January 1980 and December 2016 using the search terms medication therapy management (MTM), telephonic MTM, comprehensive medication reviews, and targeted medication reviews. This search was limited to publications in English. Case reports were excluded. RESULTS: CMRs conducted telephonically as part of an MTM program may potentially reduce healthcare expenditures, hospitalizations, and mortality. CONCLUSIONS: Although study results have shown telephonic CMRs to be an effective way to enhance patient care and reduce healthcare expenditures, the components of telephonic MTM programs that make them most effective and the population on which they have the greatest impact are unknown. Moving forward, further evaluation of these programs is necessary to determine which specific factors, such as access to patient electronic health records, patient follow-up frequency, and the use of collaborative practice agreements, are most vital to improving patient outcomes. PMID- 29461852 TI - Variation in markups on outpatient oncology services in the United States. AB - OBJECTIVES: Price markups are a major cause of healthcare inflation and financial harm to patients, especially those who are self-paying or covered by commercial insurance. STUDY DESIGN: Retrospective analysis of publicly-available information on Medicare physician payments, representing 100% of Part B services provided to fee-for-service beneficiaries during calendar year 2014. METHODS: Outcomes were markup ratios for oncology services, defined as the ratio of submitted charges to the amount reimbursed by Medicare. For example, the overall cost-to-charge ratio for all Medicare-reimbursed services in 2013 was 3.4, or a 240% charge markup. RESULTS: Our analysis included oncology services provided by 3248 hospitals in all 50 states. There was significant variation in markup ratios by hospital across oncology specialty: radiology (median = 3.7; interquartile range [IQR], 3.1-4.5), hematology/oncology (median = 2.3; IQR, 1.8-2.9), medical oncology (median = 2.4; IQR, 1.8-3.0), pathology (median = 4.1; IQR 3.1-5.1), and radiation oncology (median = 3.6; IQR, 2.9-4.5). Higher markups were associated with for-profit status for medical oncology services (coefficient, 0.29; 95% CI, 0.12-0.45) and prestige status for radiology (0.53; 95% CI, 0.15-0.92) and pathology (0.65; 95% CI, 0.20-1.09) services. CONCLUSIONS: High markups exist for oncology services, and further legislation is needed to protect patients from highly variable pricing and to address disparities in access to high-quality cancer care. PMID- 29461853 TI - Community navigators reduce hospital utilization in super-utilizers. AB - OBJECTIVES: Super-utilizers place a significant burden on the healthcare system. Blending the roles of patient navigators and community health workers may address the clinical and social needs of these patients. This study evaluated the effectiveness of community navigators in reducing hospital utilization and costs among super-utilizers from a low-income area in Memphis, Tennessee. STUDY DESIGN: Controlled pre-post (difference-in-differences [DID]) design using Methodist Le Bonheur Healthcare electronic health records from 2013 to 2016. METHODS: Data were abstracted for 1 year pre- and post intervention for super-utilizers working with a community navigator (n = 159) and a control group of similar super utilizers (n = 280). We compared utilization (hospital encounters, total hospital days, days between encounters, 30-day readmissions) and costs before and after working with a navigator for the intervention group with utilization and costs in a control group not working with a navigator and compared relative changes using a DID approach. RESULTS: Utilization and cost outcomes for intervention and control groups declined significantly from the pre- to postintervention periods. Relative to the control group, super-utilizers working with community navigators had an additional 13% reduction in hospital encounters (95% CI, -19% to -6%), 8% reduction in total hospital days (95% CI, -14% to -2%), and 9% increase in days between encounters (95% CI, 4%-15%). The intervention group also had additional reductions in 30-day readmissions (-18%; 95% CI, -44% to 22%) and costs (-$4903; 95% CI, -$13,579 to $3774), but these were not statistically significant. CONCLUSIONS: Community navigators can reduce subsequent hospital utilization in super-utilizers. Expansions of this model should examine the model's effectiveness in other populations and outcomes. PMID- 29461854 TI - Data breach locations, types, and associated characteristics among US hospitals. AB - OBJECTIVES: The objectives of this study were to describe the locations in hospitals where data are breached, the types of breaches that occur most often at hospitals, and hospital characteristics, including health information technology (IT) sophistication and biometric security capabilities, that may be predicting factors of large data breaches that affect 500 or more patients. STUDY DESIGN: The Office of Civil Rights breach data from healthcare providers regarding breaches that affected 500 or more individuals from 2009 to 2016 were linked with hospital characteristics from the Health Information Management Systems Society and the American Hospital Association Health IT Supplement databases. METHODS: Descriptive statistics were used to characterize hospitals with and without breaches, data breach type, and location/mode of data breaches in hospitals. Multivariate logistic regression analysis explored hospital characteristics that were predicting factors of a data breach affecting at least 500 patients, including area characteristics, region, health system membership, size, type, biometric security use, health IT sophistication, and ownership. RESULTS: Of all types of healthcare providers, hospitals accounted for approximately one-third of all data breaches and hospital breaches affected the largest number of individuals. Paper and films were the most frequent location of breached data, occurring in 65 hospitals during the study period, whereas network servers were the least common location but their breaches affected the most patients overall. Adjusted multivariate results showed significant associations among data breach occurrences and some hospital characteristics, including type and size, but not others, including health IT sophistication or biometric use for security. CONCLUSIONS: Hospitals should conduct routine audits to allow them to see their vulnerabilities before a breach occurs. Additionally, information security systems should be implemented concurrently with health information technologies. Improving access control and prioritizing patient privacy will be important steps in minimizing future breaches. PMID- 29461855 TI - ACA Marketplace premiums and competition among hospitals and physician practices. AB - OBJECTIVES: To examine the association between annual premiums for health plans available in Federally Facilitated Marketplaces (FFMs) and the extent of competition and integration among physicians and hospitals, as well as the number of insurers. STUDY DESIGN: We used observational data from the Center for Consumer Information and Insurance Oversight on the annual premiums and other characteristics of plans, matched to measures of physician, hospital, and insurer market competitiveness and other characteristics of 411 rating areas in the 37 FFMs. METHODS: We estimated multivariate models of the relationship between annual premiums and Herfindahl-Hirschman indices of hospitals and physician practices, controlling for the number of insurers, the extent of physician hospital integration, and other plan and rating area characteristics. RESULTS: Premiums for Marketplace plans were higher in rating areas in which physician, hospital, and insurance markets were less competitive. An increase from the 10th to the 90th percentile of physician concentration and hospital concentration was associated with increases of $393 and $189, respectively, in annual premiums for the Silver plan with the second lowest cost. A similar increase in the number of insurers was associated with a $421 decrease in premiums. Physician-hospital integration was not significantly associated with premiums. CONCLUSIONS: Premiums for FFM plans were higher in markets with greater concentrations of hospitals and physicians but fewer insurers. Higher premiums make health insurance less affordable for people purchasing unsubsidized coverage and raise the cost of Marketplace premium tax credits to the government. PMID- 29461856 TI - Cost-effectiveness of collaborative care for depression and PTSD in military personnel. AB - OBJECTIVES: Collaborative care is an effective approach for treating posttraumatic stress disorder (PTSD) and depression within the US Military Health System (MHS), but its cost-effectiveness remains unstudied. Our objective was to evaluate the costs and cost-effectiveness of centrally assisted collaborative telecare (CACT) versus optimized usual care (OUC) for PTSD and depression in the MHS. STUDY DESIGN: A randomized trial compared CACT with OUC. Routine primary care screening identified active-duty service members with PTSD or depression. Eligible participants (N = 666) were randomized to CACT or OUC and assessed at 3, 6, and 12 months. OUC patients could receive care management and increased behavioral health support. CACT patients could receive these services plus stepped psychosocial treatment and routine centralized team monitoring. METHODS: Quality-adjusted life-years (QALYs) were derived from the 12-Item Short Form Health Survey. Claims and case management data were used to estimate costs. Cost effectiveness analyses were conducted from a societal perspective. RESULTS: Data from 629 patients (320 CACT and 309 OUC) with sufficient follow-up were analyzed. CACT patients gained 0.02 QALYs (95% CI, -0.001 to 0.03) relative to OUC patients. Twelve-month costs, including productivity, were $987 (95% CI, -$3056 to $5030) higher for CACT versus OUC. CACT was estimated to cost $49,346 per QALY gained compared with OUC over 12 months. There is a 58% probability that CACT is cost-effective at a $100,000/QALY threshold. CONCLUSIONS: Despite its higher costs, CACT appears to be a cost-effective strategy relative to OUC for managing PTSD and depression in the MHS. PMID- 29461857 TI - Pricing of monoclonal antibody therapies: higher if used for cancer? AB - OBJECTIVES: The rising prices of specialty drugs have prompted a debate about how medications are priced. With the average price of cancer drugs doubling in the last decade, the unsustainability of drug prices is especially concerning in oncology and hematology. The objective of this study was to compare the prices of monoclonal antibodies (mAbs) approved in the last 20 years by the FDA across disease states. STUDY DESIGN: We identified all indications approved by the FDA for mAbs from 1997 to 2016 and calculated the annual price of 1-year treatment for each mAb-indication combination as the product of the US average wholesale price per milligram and the recommended dose. METHODS: We compared the annual price of treatment with each mAb across disease states using generalized linear models with gamma distribution and log link, controlling for route of administration, chemical structure, source, and time since FDA approval. RESULTS: The average annual price of a mAb was $96,731, exceeding $100,000 for 34 mAb indication combinations. Oncology and hematology mAbs represented 40% of the mAb indication combinations approved, yet they accounted for more than 85% of those priced $100,000 or higher. After adjusting for factors that can affect production costs, the annual price of oncology or hematology mAbs was $149,622 higher than those used in cardiovascular or metabolic disorders; $98,981 higher than in immunology; $128,856 higher than in infectious diseases or allergy; and $106,830 higher than in ophthalmology (all P <.001). CONCLUSIONS: The annual price of mAb therapies is about $100,000 higher in oncology and hematology than in other disease states. PMID- 29461858 TI - Effect of Meridian Acupressure on Aerobic Performance of Healthy Young Population: A Randomized Controlled Study. AB - OBJECTIVES: An enhancement of aerobic capacity has always been in the scope of various exercise programs. Apart from traditional, like endurance training, methods to improve aerobic performance, there is growing interest to alternative bodywork techniques, like massage, yoga, and acupuncture. This study aimed to investigate the acupressure effect on maximal aerobic capacity (VO2max) in healthy young adult males. DESIGN: Forty young healthy participants were randomly divided into intervention (n = 20) and control (n = 20) groups. The inferred VO2max level in groups was assessed by the 6-min Harvard step test twice: at baseline and after acupressure session. INTERVENTION: Three-minute finger-tip point massage of Neiguan, Juque, and Xinshu acupoints covered by 1 cm2 sticky capsaicin-dressed heat plasters was applied in the intervention group, whereas in the control group, placebo acupressure was utilized. RESULTS: The inferred VO2max in the intervention group increased from baseline 2.38 +/- 0.48 L/min to 2.57 +/- 0.6 L/min (p < 0.003), whereas inferred VO2max of the control group remained unchanged (2.46 +/- 0.5 L/min at baseline and 2.47 +/- 0.4 L/min after placebo acupressure, p > 0.9). CONCLUSIONS: The results of the study demonstrated that finger-tip acupressure increases aerobic performance of young healthy males on more than 10%. Acupressure probably decreased anxiety level, which allowed better utilization of available energy sources.

AB - OBJECTIVES: To translate the Mental Fatigue Scale into a Chinese version (CMFS), to develop a more valid and precise CMFS by using an item response theory-based model, and to examine the reliability and validity of the CMFS. METHODS: One hundred and fifty adults having traumatic brain injury for at least 6 months were included. Each participant completed a battery of questionnaires (i.e. the Chinese version of the Chalder Fatigue Scale [ChCFS], Chinese version of the Clinically Useful Depression Outcome Scale [CUDOS-Chinese], and CMFS). Two parameter graded response models were used to evaluate the location and discrimination performance of the CMFS. The reliability and validity of the CMFS were also evaluated. RESULTS: One item investigating 'increased sleep at night' (item 14) was removed because it had a low discrimination value (0.86) and provided less information. The internal consistency and test-retest reliability of the 13-item CMFS were high (0.92 and 0.96, respectively). The CMFS score was positively correlated with the ChCFS and the CUDOS-Chinese scores (r = 0.77 and 0.80, respectively). CONCLUSION: The CMFS provides reliable and valid information on mental fatigue for future research and clinical practice involving patients with traumatic brain injury. PMID- 29461862 TI - Superbubbles, Ultrabubbles, and Cacti. AB - A superbubble is a type of directed acyclic subgraph with single distinct source and sink vertices. In genome assembly and genetics, the possible paths through a superbubble can be considered to represent the set of possible sequences at a location in a genome. Bidirected and biedged graphs are a generalization of digraphs that are increasingly being used to more fully represent genome assembly and variation problems. In this study, we define snarls and ultrabubbles, generalizations of superbubbles for bidirected and biedged graphs, and give an efficient algorithm for the detection of these more general structures. Key to this algorithm is the cactus graph, which, we show, encodes the nested decomposition of a graph into snarls and ultrabubbles within its structure. We propose and demonstrate empirically that this decomposition on bidirected and biedged graphs solves a fundamental problem by defining genetic sites for any collection of genomic variations, including complex structural variations, without need for any single reference genome coordinate system. Further, the nesting of the decomposition gives a natural way to describe and model variations contained within large variations, a case not currently dealt with by existing formats [e.g., variant cell format (VCF)].

PMID- 29461864 TI - Ectopic Expression of JcWRKY Confers Enhanced Resistance in Transgenic Tobacco Against Macrophomina phaseolina. AB - Plants possess an innate immune system comprising of a complex network of closely regulated defense responses involving differential gene expression mediated by transcription factors (TFs). The WRKYs comprise of an important plant-specific TF family, which is involved in regulation of biotic and abiotic defenses. The overexpression of JcWRKY resulted in improved resistance in transgenic tobacco against Macrophomina phaseolina. The production of reactive oxygen species (ROS) and its detoxification through antioxidative system in the transgenics facilitates defense against Macrophomina. The enhanced catalase activity on Macrophomina infection limits the spread of infection. The transcript expression of antioxidative enzymes gene (CAT and SOD) and salicylic acid (SA) biosynthetic gene ICS1 showed upregulation during Macrophomina infection and combinatorial stress. The enhanced transcript of pathogenesis-related genes PR-1 indicates the accumulation of SA during different stresses. The PR-2 and PR-5 highlight the activation of defense responses comprising of activation of hydrolytic cleavage of glucanases and thaumatin-like proteins causing disruption of fungal cells. The ROS homeostasis in coordination with signaling molecules regulate the defense responses and inhibit fungal growth. PMID- 29461865 TI - Validation of auditory detection response task method for assessing the attentional effects of cognitive load. AB - OBJECTIVES: There are 3 standardized versions of the Detection Response Task (DRT), 2 using visual stimuli (remote DRT and head-mounted DRT) and one using tactile stimuli. In this article, we present a study that proposes and validates a type of auditory signal to be used as DRT stimulus and evaluate the proposed auditory version of this method by comparing it with the standardized visual and tactile version. METHODS: This was a within-subject design study performed in a driving simulator with 24 participants. Each participant performed 8 2-min-long driving sessions in which they had to perform 3 different tasks: driving, answering to DRT stimuli, and performing a cognitive task (n-back task). Presence of additional cognitive load and type of DRT stimuli were defined as independent variables. DRT response times and hit rates, n-back task performance, and pupil size were observed as dependent variables. RESULTS: Significant changes in pupil size for trials with a cognitive task compared to trials without showed that cognitive load was induced properly. Each DRT version showed a significant increase in response times and a decrease in hit rates for trials with a secondary cognitive task compared to trials without. Similar and significantly better results in differences in response times and hit rates were obtained for the auditory and tactile version compared to the visual version. There were no significant differences in performance rate between the trials without DRT stimuli compared to trials with and among the trials with different DRT stimuli modalities. CONCLUSIONS: The results from this study show that the auditory DRT version, using the signal implementation suggested in this article, is sensitive to the effects of cognitive load on driver's attention and is significantly better than the remote visual and tactile version for auditory-vocal cognitive (n back) secondary tasks. PMID- 29461866 TI - The Prognostic Value of Combinations of Genetic Polymorphisms in the ITGB3, ITGA2, and CYP2C19*2 Genes in Predicting Cardiovascular Outcomes After Coronary Bypass Grafting. AB - AIM: To determine if there are any associations between the single nucleotide polymorphisms (SNPs): rs2046934, rs1126643, rs5918, rs6065, rs4244285; rs4986893 and the occurrence of cardiovascular events (CVE) in patients following coronary artery bypass grafting (CABG) surgery. MATERIALS AND METHODS: The study included 130 CABG patients with stable angina grades II-IV. After CABG 69 of the patients were treated with acetylsalicylic acid (ASA) alone, and 61 received dual antiplatelet therapy (ASA+clopidogrel). Platelet function was assessed by light transmission aggregometry with adenosinediphosphate and arachidonic acid. The SNPs were identified by real-time polymerase chain reaction (PCR) with electrophoretic detection. The mean follow-up period was equal to 10.9 +/- 5.2 months. The primary end point included the composite of all-cause mortality, myocardial infarction (MI), and ischemic stroke. RESULTS: During the follow-up period 12 CVE were registered: 3 deaths, 6 MI, 3 strokes. Patients with composite mutant alleles of ITGB3+CYP2C19*2 or CYP2C19*2 + ITGA2, and with the mutant allele (*2) of CYP2C19, met end points more often than patients with other gene combinations (wild-type homozygotes, presence of one mutant allele of ITGB3 or ITGA2, the composite of mutant alleles of ITGB3+ITGA2 or ITGB3+ITGA2+CYP2C19*2; hazard ratio = 4, 95% confidence interval: 2.19-7.29, p = 0.008). CONCLUSION: Carriage of a combination of mutant alleles in multiple genes including ITGB3+CYP2C19*2 or CYP2C19*2 + ITGA2 or CYP2C19*2 are possible predictors of CVE in patients after CABG. PMID- 29461867 TI - Associations Between Three CTLA-4 Polymorphisms and Hashimoto's Thyroiditis Risk: An Updated Meta-Analysis with Trial Sequential Analysis. AB - AIMS: In this article, we conducted an updated meta-analysis with trial sequential analysis (TSA) to refine the associations between three common single nucleotide polymorphisms (SNPs) in the CTLA-4 gene (+49A/G, CT60, and -318C/T) and Hashimoto's thyroiditis (HT). METHODS: Statistical association analyses were performed using four genetic models, including the allelic, codominant, dominant, and recessive models with the Revman 5.3, Stata 14.0, and TSA 0.9 software. For quality evaluation, the Newcastle-Ottawa Scale was used. RESULTS: Our meta analysis included 29 independent studies with low risk of bias that involved 3614 cases and 8839 controls. The pooled results indicated a significant association between the +49A/G polymorphism and an increased risk of HT in all four genetic models. Furthermore, the TSA demonstrated that the evidence of this association was robust and credible. Subgroup analysis revealed a significantly higher risk of HT in Asians compared with Caucasians associated with the +49A/G polymorphism. Surprisingly, in contrast to the results with adults, we did not find any significant association when analyzing the pediatric subgroup. For the CT60 polymorphism, a significant association with risk of HT was detected overall, and subgroup analysis revealed that this association was significant in the Asian subgroup, but not in the Caucasian subgroup. No statistically significant associations were detected in any of the investigated genetic models for the 318C/T polymorphism. However, the results of the TSA suggested that the sample sizes used for the CTLA-4 CT60 and -318C/T SNPs were insufficient. CONCLUSION: Our meta-analysis showed significant associations between the risk of HT and both the +49A/G and CT60 polymorphisms, but not the -318C/T polymorphism. In addition, the TSA results indicated that CTLA-4 +49A/G should be considered as a biomarker for HT, whereas both the CT60 and -318C/T SNPs warrant confirmation by further studies. PMID- 29461868 TI - Genome-wide identification, characterization, and transcriptional analysis of the metacaspase gene family in cucumber (Cucumis sativus). AB - Metacaspase (MC), a family of caspase-like proteins, plays vital roles in regulating programmed cell death (PCD) during development and in response to stresses in plants. In this study, five MC genes (designated as CsMC1 to CsMC5) were identified in the cucumber (Cucumis sativus) genome. Sequence analysis revealed that CsMC1-CsMC3 belong to type I MC proteins, while CsMC4 and CsMC5 are type II MC proteins. Phylogenetic tree and conserved motif analysis of MC proteins indicated that these proteins can be classified into two groups, which are correlated with the types of these MC proteins. Gene structure analysis demonstrated that type I CsMC genes contain 4-7 introns, while all type II CsMC genes harbor one intron. In addition, many hormone-, stress-, and development related cis-elements were identified in the promoter regions of CsMC genes. Expression analysis using RNA-seq data revealed that CsMC genes have distinct expression patterns in various tissues and developmental stages. qRT-PCR results showed that the transcript levels of CsMC genes could be regulated by various abiotic stresses such as NaCl, PEG, and cold. These results demonstrate that the cucumber MC gene family may function in tissue development and plant stress responses. PMID- 29461869 TI - Volcanogenic Pseudo-Fossils from the ~3.48 Ga Dresser Formation, Pilbara, Western Australia. AB - The ~3.48 billion-year-old Dresser Formation, Pilbara Craton, Western Australia, is a key geological unit for the study of Earth's earliest life and the habitats it occupied. Here, we describe a new suite of spheroidal to lenticular microstructures that morphologically resemble some previously reported Archean microfossils. Correlative microscopy shows that these objects have a size distribution, wall ultrastructure, and chemistry that are incompatible with a microfossil origin and instead are interpreted as pyritized and silicified fragments of vesicular volcanic glass. Organic kerogenous material is associated with much of the altered volcanic glass; variable quantities of organic carbon line or fill the insides of some individual vesicles, while relatively large, tufted organic-rich laminae envelop multiple vesicles. The microstructures reported herein constitute a new type of abiogenic artifact (pseudo-fossil) that must be considered when evaluating potential signs of early life on Earth or elsewhere. In the sample studied here, where hundreds of these microstructures are present, the combined evidence permits a relatively straightforward interpretation as vesicular volcanic glass. However, reworked, isolated, and silicified microstructures of this type may prove particularly problematic in early or extraterrestrial life studies since they adsorb carbon onto their surfaces and are readily pyritized, mimicking a common preservation mechanism for bona fide microfossils. In those cases, nanoscale analysis of wall ultrastructure would be required to firmly exclude a biological origin.

PMID- 29461870 TI - Randomized, double-blind, crossover study of the adhesiveness of two formulations of rotigotine transdermal patch in patients with Parkinson's disease. AB - OBJECTIVE: In patch-based transdermal drug delivery, adhesiveness is critical for safe and effective treatment, especially in Parkinson's disease (PD) where excessive sweating is common. This study compared the adhesiveness of two transdermal patch formulations of rotigotine (improved room temperature-stable [PR2.3.1/Treatment A] and intermediate cold storage product [PR2.1.1/Treatment B]), using the largest patch size (40 cm2). METHODS: PD0018 (NCT02230904) was a multicenter, randomized, double-blind, crossover study. PD patients received Treatments A and B in randomized order for 2 days each. Patch adhesiveness was measured immediately after patch application and 24 hours thereafter (before removal). Primary variable: change in average investigator-rated adhesiveness score between treatments, per modified European Medicines Agency scale (EMA/CHMP/QWP/911254/2011, 2012). RESULTS: Fifty-seven patients were randomized; 56 patients completed the study. Five patients were excluded from analysis for accidental unblinding. Treatment A had better average adhesiveness score (mean +/ SD Treatment A - Treatment B: 1.115 +/- 1.635). A higher percentage of patients on both days had patch adhesiveness >=95% at 24 hours for Treatment A (first day: 65.4%, second day: 71.2%) vs. Treatment B (46.2%, 36.5%), and were satisfied with patch adhesiveness of Treatment A (first day: 75.0%, second day: 73.1%) vs. Treatment B (65.4%, 59.6%). Average patch-wear duration was similar between formulations (23.761 hours vs. 23.495 hours per patch). Both formulations were well tolerated with no new safety observations. CONCLUSION: Results indicated greater adhesiveness for the improved room temperature-stable formulation (PR2.3.1) vs. intermediate cold storage product (PR2.1.1) using the largest patch size, with comparable safety and skin tolerability. PMID- 29461871 TI - Continuous, comprehensive and crucial care: The role of the CNS in the metastatic castration-resistant prostate cancer patient pathway. AB - Several treatment options are now available to men with metastatic castration resistant prostate cancer (mCRPC). While survival rates for mCRPC continue to improve, patients are faced with increasingly complex treatment pathways and decisions. The clinical nurse specialist (CNS) plays a crucial role in navigating patients with mCRPC through their treatment pathway and fulfils a number of key responsibilities, including providing holistic care and support to patients and their families, educating and communicating with them in a timely and effective manner, and liaising with other healthcare professionals to seamlessly coordinate patient treatment. However, increasing patient caseloads and administrative duties are leaving CNSs with little time to fulfil their supportive role. Additional resources are needed in order to both promote and preserve this supportive role, thus ensuring that mCRPC patients receive the best possible care. PMID- 29461872 TI - Patients' Attitudes Towards the Return of Incidental Findings After Research with Residual Tissue: A Mixed Methods Study. AB - AIMS: To investigate the attitudes of patients toward the return of individual research results from scientific research with residual tissue. METHODS AND FINDINGS: We recruited 1319 patients from 6 Dutch hospitals. In total, 673 patients (51% response rate) completed the questionnaire and 146 were interviewed. Based on the questionnaire data, the majority of respondents (92%) wanted to be informed of incidental findings about both a curable (92%) and an incurable (76%) disease. Respondents' wishes to be informed about incidental findings did not vary significantly as a function of patient demographics or type of disease. The interview data show that respondents wished to be informed about incidental findings because they considered it to be normal practice; they expected the information to be of benefit for their health. Information should be provided by their physician. Yet, most respondents (84%) would consent to research even if they would not be informed about incidental findings, primarily because they recognized that there might be practical problems in providing such information, and because they valued scientific research highly. CONCLUSIONS: We conclude that, while the majority of patients want to be informed about incidental findings, they also recognize that this may be difficult. PMID- 29461874 TI - Grohar: Automated Visualization of Genome-Scale Metabolic Models and Their Pathways. AB - Genome-scale metabolic models (GEMs) have become a powerful tool for the investigation of the entire metabolism of the organism in silico. These models are, however, often extremely hard to reconstruct and also difficult to apply to the selected problem. Visualization of the GEM allows us to easier comprehend the model, to perform its graphical analysis, to find and correct the faulty relations, to identify the parts of the system with a designated function, etc. Even though several approaches for the automatic visualization of GEMs have been proposed, metabolic maps are still manually drawn or at least require large amount of manual curation. We present Grohar, a computational tool for automatic identification and visualization of GEM (sub)networks and their metabolic fluxes. These (sub)networks can be specified directly by listing the metabolites of interest or indirectly by providing reference metabolic pathways from different sources, such as KEGG, SBML, or Matlab file. These pathways are identified within the GEM using three different pathway alignment algorithms. Grohar also supports the visualization of the model adjustments (e.g., activation or inhibition of metabolic reactions) after perturbations are induced. PMID- 29461873 TI - Identification of the Functional Autophagy-Regulatory Domain in HCLS1-Associated Protein X-1 That Resists Against Oxidative Stress. AB - HCLS1 Associated Protein X-1 (HAX1) promotes cell survival through attenuation of the damaged signals from endoplasmic reticulum and mitochondria, which are known as prominent intracellular compartments for the autophagic process under stress conditions. This study investigates whether autophagy can be upregulated in response to HAX1 overexpression and identifies the functional motif in HAX1 responsible for the autophagic induction. Autophagosome accumulation, mitochondrial membrane potential (Deltapsim), and apoptosis were assessed in HEK293 cells post transduction with full-length or truncated HAX1-encoding genes, while empty vector-transduced cells served as control. Upon the oxidative stress, the enhanced autophagy induction was observed in cells overexpressing HAX1, as well as HAX1 truncations that encode peptide segments ranging from amino acids 127-180 (AA127-180). This protective response was further supported by flow cytometry and Western Blot results, in which oxidative stress-induced Deltapsim dissipation and the programmed cell death were suppressed in HAX1-overexpressing cells, associated with reduced DNA fragmentation and decreased Caspase-9 cleavage. Interestingly, the HAX1-induced autophagy response was abrogated when AA127-180 was removed, compromising the antiapoptotic effects upon oxidative stress. Overall, these data indicate that autophagy induction is involved in HAX1 induced cell protective mechanism, and AA127-180 serves as the functional autophagy-regulatory domain of this antiapoptotic protein. PMID- 29461875 TI - Assessing adherence to inhaled medication in asthma: Impact of once-daily versus twice-daily dosing frequency. The ATAUD study. AB - INTRODUCTION: This study was aimed at evaluating whether once-daily regimens (od r) show benefits in adherence when compared to twice-daily (td-r). METHODS: Prospective, multicenter, 6-month follow-up study with two visits. The main objective was to compare adherence assessed by the electronic prescription refill rate (EPRR) and by the 10-item Test of Adherence to Inhalers (TAI) in patients with od-r and td-r. Suboptimal adherence was defined as TAI < 50 or EPRR <= 80%. The effect of suboptimal adherence on meaningful clinical outcomes and the concordance between EPRR and TAI were also examined. RESULTS: One hundred and ninety-seven patients (47.3 +/- 15.9 years, 65% women) were included and 180 completed the study. TAI score was <50 in 29.8% od-r patients and 46.9% in td-r (p = 0.01) and EPRR was <=80% in 22.6% and 37.5% respectively (p = 0.02). The correlation between the two methods was moderate (rho = 0.548; p < 0.001). There were no significant differences in FEV1 (%), symptoms or exacerbations between patients with optimal and suboptimal adherence. During follow-up, five patients (6%) with o-dr and 17 patients (17.7%) with t-dr suffered an exacerbation (p = 0.013). At visit two, 13.1% of the patients with o-dr and 31.3% with t-dr had uncontrolled asthma (p = 0.003), although more patients with o-dr were receiving inhaled corticosteroids in the high-dose stratum (25.8% vs. 11.5%; p = 0.001). CONCLUSION: Mean adherence rates were greater with od-r than with td-r, but we did not observe an effect on clinical outcomes. PMID- 29461876 TI - Voice Quality in Adults Treated for Unilateral Cleft Lip and Palate: Long-term Follow-up After 1- or 2-Stage Palate Repair. AB - OBJECTIVES: The aim of the current study was to assess voice quality among adults treated for unilateral cleft lip and palate (UCLP), after 1- or 2-stage palate closure, and compare it to a noncleft control group. STUDY DESIGN: Cross sectional study in UCLP patients with long-term follow-up and noncleft controls. PARTICIPANTS: UCLP patients born 1960-1987, treated at Uppsala University Hospital, Sweden, were examined (n = 73) at a mean of 35 years after primary surgery. Forty-seven patients (64%) had been treated with 1-stage palate closure and 26 with 2-stage closure (36%). The noncleft control group consisted of 63 age matched volunteers. MAIN OUTCOME MEASURE(S): Ratings of perceptual voice characteristics from blinded voice recordings with Swedish Voice Evaluation Approach (SVEA) method. Acoustic voice analysis including pitch and spectral measures. RESULTS: Among the patients, the mean values for the 12 evaluated variables on a VAS scale (0 = no abnormality, 100 = maximal abnormality) ranged between 1 and 22 and the mean for all was 6 mm. Voice variables were similar between patients and controls except the total mean of all the perceptual voice variables, as well as "vocal fry"-both slightly lower among patients ( P = .018 and P = .009). There was no difference in any variable between patients treated with 1-stage and 2-stage palate closure. No clear relationship was found between VPI and dysphonia. CONCLUSION: The voice characteristics among adults treated for UCLP in childhood are not different from those of individuals without cleft. PMID- 29461877 TI - Active Presurgical Infant Orthopedics for Unilateral Cleft Lip and Palate: Intercenter Outcome Comparison of Latham, Modified McNeil, and Nasoalveolar Molding. AB - OBJECTIVE: To compare dental arch relationship, craniofacial form, and nasolabial aesthetic outcomes among cleft centers using distinct methods of presurgical infant orthopedics (PSIO). DESIGN: Retrospective cohort study. SETTING: Four cleft centers in North America. PATIENTS: One hundred ninety-one children with repaired complete unilateral cleft lip and palate (CUCLP). MAIN OUTCOME MEASURES: Dental arch relationship was assessed using the GOSLON Yardstick. Craniofacial form was assessed by 12 cephalometric measurements. Nasolabial aesthetics were assessed using the Asher-McDade system. Assessments were performed between 6 and 12 years of age. RESULTS: The center that used no PSIO achieved the most favorable dental arch relationship and maxillomandibular relationship, with a median GOSLON score of 2.3 ( P < .01) and an ANB angle of 5.1 degrees ( P < .05). The proportion of children assigned a GOSLON score of 4 or 5, predictive of the need for orthognathic surgery in adolescence, was 16% at the center that used no PSIO and no secondary surgery, compared to 76% at the centers that used the Latham appliance and early secondary lip and nose surgery ( P < .01). The center that used no PSIO and no secondary surgery achieved significantly less favorable nasolabial aesthetic outcomes than the centers using Latham appliance or nasoalveolar molding (NAM) ( P < .01). CONCLUSIONS: Effects of active PSIO are multifaceted and intertwined with use of revision surgery. In our study, centers using either the Latham appliance combined with early revision surgery or the NAM appliance without revision surgery achieved better nasolabial aesthetic outcomes but worse maxillary growth, compared to a center using no PSIO and secondary surgery. PMID- 29461878 TI - Experience of parents of children with autism on YouTube: are there educationally useful videos? AB - The aims of this study were to determine the following: first, are there educationally useful videos of parents of children with autism sharing their experiences? Second, do any of the data related to videos help in identifying useful videos? And third, what do posted comments tell us? YouTube was searched for videos of parents sharing their experiences. The following parameters were collected: title, creator, URL, duration, number of viewers, likes, dislikes, comments, days on YouTube, and country. Based on agreed-upon criteria, videos were divided independently into educationally useful and non-useful categories. A critical thematic analysis of comments was conducted. A total of 180 videos were finally identified, of which 106 (59%) provided useful information, scoring 15.3 +/- 0.7 (mean +/- SD); 74 (41%) were determined to be not educationally useful, scoring 8.6 +/- 2.1. The differences in scores were significant (p < 0.001), but there were no significant differences between the useful and non-useful groups in terms of video parameters. No correlation was found between scores and any of the videos' parameters. In conclusion, there are videos that can be used as educational resources. The videos' parameters did not differentiate between useful and non useful. Useful videos were mostly created by professional societies and by parents. The study reflects the emerging role of YouTube in sharing experiences. PMID- 29461879 TI - Comparing the effectiveness of laser vs. conventional endoforehead lifting. AB - The objective of this study was to compare the efficacy and safety of laser versus conventional endoforehead lifting. Over a period of 12 years (January 2000 January 2012), a total of 110 patients with hyperactive muscles over the frontal region have been collected for a retrospective study. The SurgiLase 150XJ CO2 laser system, in conjunction with the flexible FIBERLASE, was used. The endoscope was 4 mm in diameter with an angle of 30 degrees . The primary efficacy measurement was the assessment of the final outcome for using laser vs. conventional methods. Both groups were observed at three weeks, six weeks and six months after surgery. The most common complication in early convalescence (three weeks) was swelling. This was followed by local paraesthesia, ecchymosis, localized hematomas and scar with alopecia. All these problems disappeared completely after the 6-month study period. Based on a chi-square analysis, there were clinically and statistically significant differences favouring the laser endoforehead surgery in the operative time, early and late complications. All patients achieved significant improvement after both laser and conventional endoforehead surgery in the final outcome. However, the early and late complications indicated a greater difference in the laser group. PMID- 29461880 TI - Expression Profiles of Six Atherosclerosis-Associated microRNAs That Cluster in Patients with Hyperhomocysteinemia: A Clinical Study. AB - The aim of this study is to discuss the hypothesis that expression of plasma atherosclerosis-associated microRNAs (miRNAs) in hyperhomocysteinemia (Hhcy) patients could predict the presence of atherosclerosis from different channels. Six plasma miRNAs (miR-145, miR-155, miR-222, miR-133, miR-217, and miR-30) selected for our study have been confirmed as critical gene regulators involved in atherosclerosis and can be steadily determined in plasma. Expression of the above six plasma circulating miRNAs revealed significant upregulation of two miRNAs (miR-133 and miR-217) and downregulation of three miRNAs (miR-145, miR 155, and miR-222). Six candidate miRNAs showed a significant correlation with homocysteine (Hcy) or lipid parameters. The results of this study indicated that miR-217 was further significantly upregulated in Hhcy + ATH groups than in normal control, Hhcy-, and atherosclerosis-alone (ATH) groups and it showed a significant negative correlation with Hcy and triglycerides. More specifically, miR-217 showed the most specific expression patterns in all patients with atherosclerosis (ATH and Hhcy + ATH groups), which may have been a diagnostic value for Hhcy complicated with atherosclerosis, and predicted the progress of atherosclerosis in Hhcy patients effectively. PMID- 29461881 TI - Insights into Macrophage Autophagy in Latent Tuberculosis Infection: Role of Heat Shock Protein 16.3. AB - Tuberculosis (TB) is a major bacterial infectious disease worldwide that is predominantly caused by Mycobacterium tuberculosis (Mtb). The comorbidity of multiple drug-resistant TB strains with HIV and diabetes is widespread. In the presence of these diseases, host immunity is weakened, allowing the recovery of dormant bacilli and leading to recurrent TB infection. As an important component of the host innate and adaptive immune responses, macrophage autophagy plays a significant role in protecting the host against TB. However, dormant bacilli can escape from autophagosomes and/or suppress autophagy, thus surviving within the host for an extended period of time, although the underlying mechanism remains elusive. Heat shock protein 16.3 (Hsp16.3, HspX, Rv2031c, and Acr) is one of the immunodominant proteins expressed during latent TB infection (LTBI). It may help maintain the protein stability and long-term viability of Mtb by inhibiting macrophage autophagy, resulting in LBTI. In this review, we discuss how dormant bacilli escape from autophagosomes, and we focus on the role of Hsp16.3 in regulating macrophage autophagy in LTBI so as to provide a firm basis for further studies. Hsp16.3 may represent a potential biomarker of LTBI and novel pharmacological target for anti-tubercular drugs. PMID- 29461883 TI - Structure and Function Relationships in Diseases of the Small Airways. AB - It is well known that particulate matter suspended in the earth's atmosphere generated by tobacco smoke, automobile exhaust, industrial processes, and forest fires has been identified as a major risk factor for chronic lung disease. Particulate matter can be divided into large, intermediate, and fine particulates. When inhaled, large particulates develop sufficient momentum to leave the flowing stream of inhaled air and deposit by impaction in the nose, mouth, nasopharynx, larynx, trachea, and central bronchi. Intermediate-sized particulates that develop less momentum deposit in the smaller bronchi and larger bronchioles, and the finest particulates that develop the least momentum make it to the distal gas-exchanging tissue, where gas moves solely by diffusion. On the basis of Einstein's classic work on Brownian motion that showed particles suspended in a gas diffuse much more slowly than the gas in which they are suspended, we postulate that the small airways that accommodate the shift from bulk airflow to diffusion become the major site for deposition of fine particles, resulting in a host immune response. Much remains to be learned about the interaction between the deposition of fine particulates and the host immune and tissue responses; the purpose of this review is to examine the hypothesis that the smallest conducting airways and proximal gas-exchanging tissue are the primary sites for the deposition of the finest particulates inhaled into the lungs. PMID- 29461882 TI - Genetic Analyses Identified a SALL4 Gene Mutation Associated with Holt-Oram Syndrome. AB - Holt-Oram syndrome (HOS) is an autosomal dominant disorder, which is characterized by deformities of upper limbs and congenital heart defects. Alterations of TBX5 gene have been identified to be the leading cause of HOS, while some cases could not be explained by TBX5 mutations. In our study, we preliminarily diagnosed a newborn baby, who had Tetralogy of Fallot, thumb agenesis, facial dysplasia, and right ear canal malformation, as HOS. Chromosome microarray analyses showed no pathological deletions or replications of chromosome segments; whole exome sequencing screened out six candidate genes that were involved in cardiac diseases or syndromes among which SALL4 has been reported as HOS related gene. We evaluated the pathogenicity of SALL4 mutant sites by series of software. The results indicated that SALL4-M143V may be a polymorphism site, and SALL4-R418C could cause disease. HOPE and SWISS PDB viewer showed that SALL4-R418C leads to changes in amino acid properties, loss of protein hydrogen bond, and functional impact of SALL4 zinc finger domain. These results further confirmed the pathogenic significance of SALL4-R418C mutant. When genetic analyses coupled with bioinformatic analyses, we identified a SALL4 gene rare mutation which might contribute to a newborn with HOS. Although some doubts need to be further discussed and explored, our study deepened the understanding of phenotype difference among syndromes and role of SALL4 mutations in disease occurrence. PMID- 29461884 TI - Cournand's and Richards' Post-Nobel Challenge: "Do Anything on the Structure of the Lung That Is of Interest for Physiology". AB - In their Nobel Lectures of 1956, the two cardiopulmonary physiologists Andre Cournand and Dickinson Richards described the future projects that they considered important for rounding up their impressive scientific achievements. One of them called for work that brought together structure and function of the lung in a systematic way. They challenged a young anatomist to undertake this in their cardiopulmonary laboratory at Bellevue Hospital. The first steps established the need for quantitative information on the structures that form the pulmonary gas exchanger as well as the airway tree. This resulted in a new approach to lung anatomy: morphometry would provide the quantitative information for modeling structure-function relations in the lung, and eventually in the entire respiratory system, thus allowing a rational analysis of how structures affect or limit functions. PMID- 29461885 TI - Physiologic Basis of Mechanical Ventilation. AB - The primary purpose of mechanical ventilation is to decrease work of breathing. Achieving this goal requires that cycling of the ventilator be carefully aligned with the intrinsic rhythm of a patient's respiratory center output. Problems arise at the point of ventilator triggering, post-trigger inflation, and inspiration-expiration switchover. Careful, iterative adjustments of ventilator settings are required to minimize work of breathing. Use of protocols for the selection of ventilator settings can lead to complications (including alveolar overdistention) and risk of death. Because complications are axiomatic to mechanical ventilation, it should be discontinued at the earliest possible time. To shorten ventilator time, the critical step is to screen for weanability through use of weaning predictor tests. Use of T-tube trials circumvents the impossibility of estimating patient work of breathing during pressure support. Before extubation, patients should demonstrate the ability to breathe successfully in the absence of pressure support and positive end-expiratory pressure. PMID- 29461886 TI - Cournand and Richards: The Nobel Prize. PMID- 29461887 TI - Cor Pulmonale Revisited. From Ferrer and Harvey to the Present. AB - The term cor pulmonale has traditionally been used as a synonym for right heart failure due to chronic respiratory diseases, although this condition is less frequently seen in the modern era because of the use of long-term oxygen therapy along with aggressive measures directed at optimizing ventilation and gas exchange. The mechanisms by which adaptation or maladaptation of right heart structure and function in the broader setting of pulmonary vascular disease, either intrinsic to the pulmonary circulation or due to respiratory diseases, have garnered considerable interest along with the development of medical and surgical treatments for pulmonary hypertension. Thus, the right heart is no longer considered an "innocent bystander" in pulmonary hypertension, but rather a key component in its pathophysiology. Furthermore, the status of right heart function is a major determinant of outcome. Accordingly, the right heart has become a potential, appealing target for novel therapies to treat hypertensive pulmonary vascular disease. PMID- 29461888 TI - Some Unanticipated Consequences of Early Cardiac Catheterization. Insights into Pulmonary Pathophysiology. AB - One of the most interesting unanticipated findings by Andre Cournand and Dickinson Richards in their groundbreaking studies of cardiac catheterization was the very low pressure in the normal pulmonary circulation. At the time, in the 1940s, the significance of this was not appreciated. For example, in their speeches at the Nobel Prize ceremony, neither of these laureates referred to the low pressure, although they did discuss other features of the pulmonary circulation. It was up to the cardiologist, William Dock, to point out that these low pressures implied a very uneven distribution of blood flow in the lung, and in particular that in the normal upright lung, the blood flow to the apex would be extremely small. Dock went on to argue that this low blood flow at the top of the lung was responsible for the characteristic apical distribution of adult pulmonary tuberculosis. Since that time, it has been recognized that the low pressures in the pulmonary circulation have many implications in pulmonary pathophysiology. For example, if the vascular pressure is further reduced, such as in hemorrhagic shock, gas exchange is seriously affected because of the development of a large alveolar dead space. Furthermore, if humans are subjected to increased acceleration, such as in a high-performance aircraft, the distribution of blood flow becomes extremely abnormal, with much of the lung being completely unperfused. There are also diseases where distribution in the lung is affected by the uneven distribution of blood flow. These include alpha-1 antitrypsin deficiency and metastatic calcification of the lung.

AB - The use of extracorporeal membrane oxygenation to support patients with cardiac and respiratory failure has increased substantially in the last decade. Although the evidence base for its use in adults with respiratory failure is growing, many questions remain to be answered. Ongoing research is aimed at clarifying the role of extracorporeal membrane oxygenation, as well as extracorporeal carbon dioxide removal, in various forms of hypoxemic and hypercapnic respiratory failure, and at defining the optimal techniques for its use. This, of course, is a moving target, as advances in the technology of extracorporeal membrane oxygenation, and the potential development of a true artificial lung, continue at a brisk pace. PMID- 29461890 TI - Small Airway Disease Syndromes. Piercing the Quiet Zone. AB - The role for direct assessment of small airway function in subjects with respiratory symptoms but normal airflow by spirometry is discussed. Small airway disease syndrome is described in numerous disease states using a multidisciplinary approach. Data demonstrate that small airway disease is related to presence of respiratory symptoms, exposure to inhaled toxins, presence of local and systemic inflammation, and presence of histologic abnormalities within the distal lung. Investigation of immunological derangements associated with distal airway dysfunction in the setting of normal spirometry may provide insight into pathophysiological mechanisms that are present at disease onset. For the purposes of this symposium, data were reviewed in selected clinical conditions (obesity, environmental inhalational injury, and cigarette smoking) that have been recently studied in the Andre Cournand Pulmonary Physiology Laboratory at Bellevue Hospital using the forced oscillation technique. PMID- 29461891 TI - Pathophysiology of Chronic Systolic Heart Failure. A View from the Periphery. AB - Heart failure is a common form of heart disease associated with progressive exercise intolerance and high risk of adverse clinical outcome events. The pathophysiology of chronic systolic heart failure is fundamentally determined by the failure of the circulatory system to deliver oxygen sufficient for metabolic needs, and it is best explained by a complex interplay between intrinsic abnormalities of ventricular pump function and extracardiac factors that limit oxygen use in metabolically active tissues. This brief review highlights the role of extracardiac factors (peripheral factors) that may impact exercise capacity in patients with chronic systolic heart failure. Reduced metabolic vasodilation limits delivery of available cardiac output reserve to skeletal muscle during exercise, and it is associated with reduced peak oxygen capacity. Abnormal substrate use in skeletal muscle due to reduced skeletal muscle mass, change in skeletal muscle fiber type, and mitochondrial dysfunction reduces work efficiency and submaximal exercise endurance capacity in patients with systolic heart failure. These extracardiac peripheral mechanisms of impaired exercise tolerance in chronic heart failure may be targets for novel therapeutic development in this patient population. PMID- 29461893 TI - Andre Cournand, Bellevue's Cardiopulmonary Laboratory, and Research on Heart Failure. AB - In 1954-1955, the author served as a research fellow in the cardiopulmonary laboratory led by Andre Cournand at Bellevue Hospital in New York. Cournand was a pulmonary physiologist and a professor of medicine at Columbia University. In his quest to obtain mixed venous blood to calculate pulmonary blood flow, he catheterized the right atrium, right ventricle, and pulmonary artery in patients and also measured the pressures in these chambers. Cournand and his collaborators soon appreciated the enormous potential of cardiac catheterization in deepening the understanding of cardiovascular pathophysiology. After a series of groundbreaking studies, Cournand and his coworker Dickinson Richards, as well as German physician Werner Forssmann, were awarded a Nobel Prize in 1956. Cournand's laboratory, his work habits, and his rigorous approach to science are described, as well as the stimulation the author received during the author's fellowship. As a result, the author went on to extend to the left side of the heart the observations that the Cournand group had conducted in the right heart. Also, the author continued Cournand's work on heart failure by developing techniques to measure ventricular function in patients and to describe the neurohumoral changes that occur in human heart failure. PMID- 29461892 TI - Human Cognitive Limitations. Broad, Consistent, Clinical Application of Physiological Principles Will Require Decision Support. AB - Our education system seems to fail to enable clinicians to broadly understand core physiological principles. The emphasis on reductionist science, including "omics" branches of research, has likely contributed to this decrease in understanding. Consequently, clinicians cannot be expected to consistently make clinical decisions linked to best physiological evidence. This is a large-scale problem with multiple determinants, within an even larger clinical decision problem: the failure of clinicians to consistently link their decisions to best evidence. Clinicians, like all human decision-makers, suffer from significant cognitive limitations. Detailed context-sensitive computer protocols can generate personalized medicine instructions that are well matched to individual patient needs over time and can partially resolve this problem. PMID- 29461894 TI - Rethinking Chronic Obstructive Pulmonary Disease. Chronic Pulmonary Insufficiency and Combined Cardiopulmonary Insufficiency. AB - Almost 70 years ago, Drs. Baldwin, Cournand, and Richards defined chronic pulmonary insufficiency by the presence of respiratory symptoms, radiologic evidence of pulmonary emphysema on chest radiography, and physiologic gas trapping. A decade later, airflow obstruction on spirometry was added to the definition and insufficiency became a disease. Contemporary studies are reviving the diagnostic approach described by these early luminaries, with researchers finding that symptomatic smokers with preserved spirometry have increased exacerbations and that smokers and non-smokers with normal spirometry but emphysema on chest computed tomography have increased mortality. Hence, the Baldwin-Cournand-Richards concept of disease defined by respiratory symptoms, radiologic findings, and physiology-regardless of spirometric criteria-is being rediscovered. Baldwin, Cournand, and Richards also stated that "functionally, it is obvious that the pulmonary and circulatory apparatus are one unit," and they defined combined cardiopulmonary insufficiency as chronic pulmonary insufficiency with (left or right) cardiac and pulmonary artery enlargement. They appreciated the complexity of these interactions, which include the potential role of gas trapping in heart failure with reduced ejection fraction; the impact of emphysema on blood flow in heart failure with preserved ejection fraction; multiple contributions to cor pulmonale with increased pulmonary artery pressure; and cor pulmonale parvus in emphysema; all of which may be amenable to specific therapeutic interventions. Given the complexity of heart-lung interactions originally identified by Baldwin, Cournand, and Richards and the potentially large therapeutic opportunities, large-scale studies are still warranted to find specific therapies for subphenotypes of combined cardiopulmonary insufficiency. PMID- 29461896 TI - Chronic Obstructive Pulmonary Disease. A Biomarker and a Potential Therapy. AB - This article assesses developments in cardiorespiratory medicine since the Nobel Prize in Physiology or Medicine was awarded in 1956 for advancements in the study of cardiorespiratory disease. In chronic obstructive pulmonary disease, advances were accelerated by the discovery of a genetically determined cause for pulmonary emphysema in the genetic abnormality alpha-1 antitrypsin deficiency. This causes a deficiency of the inhibitor of neutrophil elastase, which results in increased degradation of lung elastin and the development of pulmonary emphysema. This discovery gave focus to two amino acids that reside only in body elastin, desmosine and isodesmosine, which can be measured as biomarkers of elastin degradation in body fluids with increased accuracy and sensitivity. Studies of this biomarker have shown that augmentation therapy in alpha-1 antitrypsin deficiency does decrease lung and body elastic tissue degradation and in the RAPID (Randomized, Placebo-controlled Trial of Augmentation Therapy in Alpha-1 Proteinase Inhibitor Deficiency) Study, over 4 years, showed a preservation of lung density by computer tomography correlating with decreases in plasma levels of desmosine and isodesmosine. This insight indicates the potential of agents that prevent lung elastin degradation. Such an agent is hyaluronan aerosol, which is deficient in post mortem lungs with chronic obstructive pulmonary disease and has been shown to block elastin degradation, possibly by a barrier function. Thus it would appear that hyaluronan could have therapeutic potential in chronic obstructive pulmonary disease. PMID- 29461895 TI - Scaling Physiologic Function from Cell to Tissue in Asthma, Cancer, and Development. AB - The formation of an integrated tissue from individual cells depends on the properties of the individual cells as well as the interaction of many cells acting as a collective. Three fundamental physiological processes govern the collective scaling from the individual cell to a working tissue: cell sorting, tissue assembly, and collective cellular migration. Mechanistically, cell sorting is governed by differential adhesion, whereas tissue assembly is controlled by the epithelial-to-mesenchymal transition and its inverse, the mesenchymal-to epithelial transition. The mechanism driving collective cellular migration, however, is not clear. To fill that gap, here we consider cell jamming and unjamming, and their role in collective cellular migration.

PMID- 29461897 TI - RNA/Protein Discordant Expression of Fndc5 in Central Nervous System Is Likely to Be Mediated Through microRNAs. AB - Fibronectin type III domain-containing 5 protein (Fndc5) is responsible for producing a secretory protein termed, "irisin." A modified expression of Fndc5 has been reported in different tissues during development, differentiation processes, as well as in metabolic events such as exercise. One of the important issues to be fixed is whether Fndc5 RNA level and protein content are concerted and modified hand in hand. Therefore, the aim of this study is to assess Fndc5 RNA and protein levels in various tissues of mouse and rat with emphasis on brain. Biopsies from various parts of neonatal and adult mouse and rat tissues were simultaneously assessed for transcript levels of Fndc5 and compared with the respective protein levels at the same time. Data indicated, unlike in muscle, no concerted fluctuations were observed for Fndc5 RNA and protein, especially in brain. Further look at four regions of brain (cerebellum, putamen, hippocampus, and cortex) revealed a similar discrepant expression. To hypothesize whether such discrepancy is arisen by miRNAs, we selected three main miRNAs, which were predicted to target Fndc5 and their expression levels were assessed in central nervous system (CNS) of mouse and hippocampus of rat. miRNA levels showed an antiparallel correlation with protein level of Fndc5, interpreting a putative role in regulating Fndc5 protein content in CNS. This phenomenon may represent the importance of governing Fndc5 content in neural cells, which seems to be crucial for neural function and differentiation. PMID- 29461899 TI - Policy Brief. PMID- 29461900 TI - Suppression of LRRC19 promotes cutaneous wound healing in pressure ulcers in mice. AB - The ischemia-reperfusion (I/R) induced skin lesion has been identified as primary cause of pressure ulcer. Better understanding of the mechanism is required for new therapy development. Leucine rich repeat containing protein 19 (LRRC19) is a recently discovered transmembrane protein containing leucine-rich repeats and plays a role in immune response. To investigate the role of LRRC19 in pressure ulcers, mouse ulcer model was established with two cycles of I/R. The expression of LRRC19 was assessed during injury. siRNA mediated LRRC19 downregulation was applied to investigate the disease severity, immune cell infiltration and pro inflammatory cytokines production. The primary skin fibroblasts were stimulated with IL-1beta to dissect the molecular mechanism. LRRC19 was readily induced in I/R induced lesion site in a pattern mimicking the disease progress as measured by wound area. Knockdown of LRRC19 by siRNA significantly alleviated the disease severity and attenuated immune cell infiltration and pro-inflammatory cytokines production. In primary skin fibroblast model, siRNA knockdown of LRRC19 suppressed IL-1beta mediated NFkappaB activation and its downstream cytokines production. LRRC19 was a novel factor for I/R-induced tissue damage by promoting NFkappaB dependent pro-inflammatory response. Our results supported that LRRC19 could be a potential therapeutic target for pressure ulcers. PMID- 29461901 TI - Predicting treatment outcome of drug-susceptible tuberculosis patients using machine-learning models. AB - Tuberculosis (TB) is a deadly contagious disease and a serious global health problem. It is curable but due to its lengthy treatment process, a patient is likely to leave the treatment incomplete, leading to a more lethal, drug resistant form of disease. The World Health Organization (WHO) propagates Directly Observed Therapy Short-course (DOTS) as an effective way to stop the spread of TB in communities with a high burden. But DOTS also adds a significant burden on the financial feasibility of the program. We aim to facilitate TB programs by predicting the outcome of the treatment of a particular patient at the start of treatment so that their health workers can be utilized in a targeted and cost-effective way. The problem was modeled as a classification problem, and the outcome of treatment was predicted using state-of-art implementations of 3 machine learning algorithms. 4213 patients were evaluated, out of which 64.37% completed their treatment. Results were evaluated using 4 performance measures; accuracy, precision, sensitivity, and specificity. The models offer an improvement of more than 12% accuracy over the baseline prediction. Empirical results also revealed some insights to improve TB programs. Overall, our proposed methodology will may help teams running TB programs manage their human resources more effectively, thus saving more lives. PMID- 29461902 TI - Excision of nodular basal cell carcinoma involving the lower eyelid tarsal skin using a grey line-splitting, posterior lamella-sparing technique. AB - PURPOSE: To describe a posterior lamella-sparing technique to resect nodular basal cell carcinoma involving the inferior part of the tarsal skin of the lower eyelid. SURGICAL TECHNIQUE: Excision of nodular basal cell carcinoma of the tarsal skin using a grey-line-splitting technique with preservation of the posterior lamella. Specimen was sent for frozen section control. Additional excision was performed in caseof irradicality. The defect was closed with a free skin graft from the ipsi- or contralateral upper eyelid. RESULTS: We show a case series of three patients with lower eyelid basal cell carcinoma and investigated radicality on histology, aesthetic outcome and clinical recurrence during a follow-up of 18 months. Pre, intra, and postoperative photographs were obtained. In all cases radicality was reached. In all patients, the skin graft was viable, with no recurrence after 18 months. Excellent aesthetic results were obtained. CONCLUSION: Anterior lamellar resection of nodular basal cell carcinomas involving the tarsal lower eyelid skin using a grey line lid-splitting technique is a simple and one-step technique with good clinical outcome. It may avoid the morbidity associated with full thickness eyelid resection and might be useful for other, nonmalignant eyelid lesions. PMID- 29461903 TI - Habilitation of very preterm infants at a Post Acute Care Inpatient Rehabilitation (PACIR) center after neonatal intensive care unit (NICU) discharge. AB - OBJECTIVE: To investigate whether Post-Acute Care Inpatient Rehabilitation (PACIR) admission after NICU stay affects the total length of stay (LOS) of very preterm (VPT: <=30 weeks of gestation) infants. METHODS: A retrospective case control study of VPT infants d/c'd from the NICU at Maria Fareri Children's Hospital (MFCH) to either a PACIR (Blythedale Children's Hospital: BH) for convalescent care (cases) or directly home (controls). RESULTS: 35 cases and 70 controls. Total LOS (MFCH + BH) was longer for cases [196 vs. 97 days]. At the time of d/c from MFCH, Special Health Care Needs (SHCN) amongst cases were greater than controls, however, became similar at the time of home d/c. The majority of cases achieved habilitation goals at the PACIR. CONCLUSIONS: Although LOS was longer for patients transferred to a PACIR, habilitation at BH Hospital reduced the SHCN at the time of home d/c amongst cases. PMID- 29461904 TI - An investigation of the association between seizures, autism symptomology, and developmental functioning in young children. AB - OBJECTIVE: The aim of the present study was to explore whether a history of seizures was associated with autism symptom severity and developmental functioning in young children. METHODS: Autism symptom severity and developmental functioning were compared between children with and without a history or seizures who either had atypical development or met criteria for autism spectrum disorder (ASD) based on review of records by a licensed clinical psychologist. RESULTS: Parents of children who met criteria for ASD reported lower levels of autism symptomology when the child had a history of seizures, while the opposite trend was found for children with atypical development. Participants without ASD or seizures had greater developmental functioning than the other groups. CONCLUSION: The present study emphasizes the need for early identification and diagnosis of both ASD and seizure disorders, as timely intervention for these two conditions may be related to improved outcomes for young children. PMID- 29461905 TI - A case and literature review of orbital microcystic adnexal carcinoma. AB - Microcystic adnexal carcinoma (MAC) is a very rare and locally aggressive sweat gland tumour. MAC has been well reported presenting as a periocular cutaneous lesion, rarely with subsequent direct orbital invasion and only once as a primary orbital lesion. Local recurrence is frequent after primary surgical excision and the role of adjuvant radiotherapy is ill-defined. We describe a case of orbital MAC treated successfully with radiotherapy after incomplete margin clearance post exenteration surgery and review the associated literature. PMID- 29461906 TI - How does measurement of platelet P-selectin compare with other methods of measuring platelet function as a means of determining the effectiveness of antiplatelet therapy? AB - Measurement of P-selectin on activated platelets as a means of measuring platelet function utilizing the technology described here has the advantage of not requiring immediate access to specialist equipment and expertise. Blood samples are activated, fixed, stored, and transported to a central laboratory for flow cytometric analysis. Here we have compared P-selectin with other more traditional approaches to measuring platelet function in blood and/or platelet-rich plasma (PRP) from patients with acute coronary syndromes on treatment for at least 1 month with either aspirin and clopidogrel or aspirin with prasugrel. The comparators were light transmission aggregometry (LTA), VerifyNow and Multiplate aggregometry (for determining the effects of aspirin) and LTA, VerifyNow and Multiplate together with the BioCytex VASP phosphorylation assay (for the P2Y12 antagonists). The P-selectin Aspirin Test revealed substantial inhibition of platelet function in all but three of 96 patients receiving aspirin with clopidogrel and in none of 51 patients receiving aspirin and prasugrel. The results were very similar to those obtained using LTA. There was only one patient with high residual platelet aggregation and low P-selectin expression. The same patients identified as "non-responders" to aspirin also presented with the highest residual platelet activity as measured using the VerifyNow system, although not quite as well separated from the other values. With the Multiplate test only one of these patients clearly stood out from the others. The results obtained using the P-selectin P2Y12 Test in 102 patients taking aspirin and clopidogrel were similar to the more traditional approaches in that a wide scatter of results was obtained. Generally, high values seen with the P-selectin P2Y12 Test were also high with the LTA, VerifyNow, Multiplate, and BioCytex VASP P2Y12 Tests. Similarly, low residual platelet function using the P2Y12 test was seen irrespective of the testing procedure used. However, there were differences in some patients. Prasugrel was always more effective than clopidogrel in inhibiting platelet function with none of 56 patients (P-selectin and VerifyNow), only 2 of 56 patients (Multiplate) and only 3 of 56 patients (Biocytex VASP) demonstrating high on-treatment residual platelet reactivity (HRPR) defined using previously published cut-off values. The exception was LTA where there were 11 of 56 patients with HRPR. It remains to be seen which experimental approach provides the most useful information regarding outcomes after adjusting therapies in treated patients. PMID- 29461907 TI - Personalizing Patients' Advance Directives Decreases the Willingness of Intensive Care Unit Residents to Stop Treatment: A Randomized Study. AB - BACKGROUND: While following patients' advance directives (ADs) is legally binding, French physicians in Intensive Care Unit (ICU) perceive them as complicating their decision. Decision making and ICU residents benefit from personalizing the dying process. In France, ADs can include personal information. OBJECTIVE: Whether personalizing ADs affects ICU residents' decisions and perception of the patient. SUBJECTS AND DESIGN: Sixty-six ICU residents assigned to three experimental groups and presented with a case file for an ICU patient. The files were identical except for the patient's AD, which was manipulated to give three conditions: No Personal Information, Sociodemographic Information, and Agency Information (ability to plan and act upon the world). MEASUREMENTS: Residents evaluated the relevance of the AD, assessed its influence on medical decisions, and decided whether to stop treatment, postpone the decision, or consult the family. Finally, they evaluated the patient with respect to two dimensions of personhood (agency and experience). RESULTS: Residents in all conditions considered the AD to be highly relevant and influential. Residents in both Information conditions perceived the patient as having more capacities for agency and for experience than those in the No Information condition. They were also less likely to stop treatment and more likely to postpone their decision. Consulting the family was not sensitive to the information condition. CONCLUSION: Personalizing ADs of an unknown patient leads ICU residents to be less prone to follow them, but does not affect whether or not they decide to consult the patient's family. Hence, promoting shared decision making by including the incapacitated patients' families in treatment decisions is a major challenge, especially in countries such as France, where ADs are legally binding. PMID- 29461908 TI - Improving Early Palliative Care with a Scalable, Stepped Peer Navigator and Social Work Intervention: A Single-Arm Clinical Trial. AB - BACKGROUND: Patients with cancer could benefit from early primary (i.e., basic) palliative care. Scalable models of care delivery are needed. OBJECTIVE: Examine the feasibility of a stepped peer navigator and social work intervention developed to improve palliative care outcomes. DESIGN: Single-arm prospective clinical trial. The peer navigator educated patients to advocate for pain and symptom management with their healthcare providers, motivated patients to pursue advance care planning, and discussed the role of hospice. The social worker saw patients with persistent psychosocial distress. SETTING/SUBJECTS: Patients with advanced cancer at a VA Medical Center not currently in palliative care or hospice whose oncologist would not be surprised if the patient died in the subsequent year. MEASUREMENTS: Participation and retention rates, patient reported symptoms and quality of life, advance directive documentation, patient satisfaction survey, and semistructured interviews. RESULTS: The participation rate was 38% (17/45), and 35% (7/17) completed final survey measures. Patients had stage IV (81%) and primarily genitourinary (47%) and lung (24%) malignancies. Median Eastern Cooperative Oncology Group performance status was 0. Patient reported surveys indicated low distress (mean scores: Functional Assessment of Cancer Therapy-General, 75.3 [standard deviation {SD} 17.6]; Edmonton Symptom Assessment Scale symptom scores ranged from 1.6 to 3.8; Patient Health Questionnaire-9, 5.7 [SD 5.2]; and Generalized Anxiety Disorder-7, 2.8 [SD 4.1]). Of those who had not completed advance directives at baseline (n = 11, 65%), five completed them by the end of study (5/11, 45%). Patients who completed satisfaction surveys (n = 7) and interviews (n = 4) provided mixed reviews of the intervention. CONCLUSIONS: At a single site, a stepped peer navigator and social work palliative care study had several challenges to feasibility, including low patient-reported distress and loss to follow-up.

AB - BACKGROUND: Since 2007, trivalent inactivated influenza vaccine has been provided free-of-charge to older adults aged >=60 years in Beijing, China, but the data regarding influenza vaccine effectiveness (VE) among these people are very limited so far. We sought to estimate influenza VE against medically-attended laboratory-confirmed influenza illness among older adults during the 2013-2014 season. METHODS: The influenza-like illness (ILI) patients aged 60 years and older who participated in the influenza virological surveillance of Beijing during 2013-2014 influenza season were recruited in this study. A test-negative design was employed to estimate influenza VE among older adults by using logistic regression models. VE was estimated using logistic regression, adjusted for sex, age, interval (days) between illness onset and specimen collection, and week of illness onset. RESULTS: Between 1 November, 2013 and 30 April, 2014, a total of 487 elderly ILI patients were enrolled in the study, including 133 influenza positive cases (of whom 6.8% were vaccinated) and 354 influenza-negative controls (of whom 10.2% were vaccinated). Among 133 influenza-positive cases, 51 tested positive for A(H1N1)pdm09 virus, 22 positive for A(H3N2) virus, 52 tested positive for B/Yamagata-lineage virus, 2 positive for B/Victoria-lineage virus, 1 positive for both A(H1N1)pdm09 and A(H3N2) viruses, and 5 tested positive for viruses of unknown subtype or lineage. The adjusted overall VE was estimated as 32% (95% CI:-48-69), with 59% (95% CI: -79-90) against A(H1N1)pdm09, 22% (95% CI: -253-83) against A(H3N2) and -20% (95% CI: -239-58) against B/Yamagata-lineage viruses. CONCLUSIONS: These results suggested a modest protective effect of the 2013-2014 influenza vaccine among older adults in Beijing which was not statistically significant, with higher VE against the A(H1N1)pdm09 viruses compared to A(H3N2) and B viruses. PMID- 29461911 TI - Small cell lung cancer transformation from EGFR-mutated lung adenocarcinoma: A case report and literatures review. AB - Epithelial growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) have markedly improved the response of non-small cell lung cancer (NSCLC) with EGFR mutant patients. However, these patients inevitably come cross acquired resistance to EGFR-TKIs. The transformation of lung adenocarcinoma to small cell lung cancer (SCLC) following treatment with EGFR-TKIs is rare, which leads to resistance to EGFR-TKIs. The present case concerns a case of a 38-year-old man presenting with cough and dyspnea. Radical resection was performed and confirmed an EGFR exon 21 L858R lung adenocarcinoma. However, the patient suffered pleural metastasis after successful treatment with surgery and adjuvant treatment. So, erlotinib was administered with 18 months. Because of enlarged pleural nodule, repeat biopsy identified an SCLC and chemotherapy was started. However, despite the brief success of chemotherapy, our patient suffered brain metastasis. Our case emaphsizes both the profile of transformation from NSCLC to SCLC and the importance of repeat biopsy dealing with drug resistance. We also summarize the clinical characteristics, mechanisms, predictors of SCLC transformation, treatment after transformation and other types of transformation to SCLC. PMID- 29461912 TI - Practice and attitudes towards immunization among Lebanese obstetricians and gynecologists. AB - We designed our study to evaluate the knowledge and immunization practices among Lebanese obstetricians and gynecologists (OBGYN) for women of different age groups. Anonymous questionnaires were used to assess the knowledge and immunization practices among OBGYN. The survey was conducted at the annual meeting of the Lebanese Society of Obstetrics and Gynecology on November 13-15, 2014. Data collected included demographics, type of practice, academic background and familiarity with vaccine guidelines. Descriptive statistical methods were used to evaluate the responses. The response rate was 54.8% (114/208). Only 62.3% (71/114) recommend vaccination(s) to pregnant women with only 25.9% of those who recommend the Tdap vaccine for pregnant women giving it during the recommended third trimester. In addition, 52.6% are unaware of the CDC/ACIP immunization schedule for women in general. However, 83.0% (93/112) of respondents are willing to integrate vaccination in their practice. Our study highlights several gaps in the knowledge of Lebanese OBGYN regarding vaccination in addition to practices that are not in full accordance with common guidelines. Measures should be taken to spread proper awareness of the proper guidelines among Lebanese practitioners. PMID- 29461910 TI - Measuring and interpreting platelet-leukocyte aggregates. AB - Platelets, besides their specialised role in haemostasis and atherothrombosis, actively modulate innate and adaptive immune responses with crucial roles in immune surveillance, inflammation and host defence during infection. An important prerequisite for platelet-mediated changes of immune functions involves direct engagement with different types of leukocytes. Indeed, increased platelet leukocyte aggregates (PLAs) within the circulation and/or locally at the site of inflammation represent markers of many thrombo-inflammatory diseases, such as cardiovascular diseases, acute lung injury, renal and cerebral inflammation. Therefore, measurement of PLAs could provide an attractive and easily accessible prognostic and/or diagnostic tool for many diseases. To measure PLAs in different (patho-)physiological settings in human and animal models flow cytometric and microscopic approaches have been applied. These techniques represent complementary tools to study different aspects relating to the involvement of leukocyte subtypes and molecules, as well as location of PLAs within tissues, dynamics of their interactions and/or dynamic changes in leukocyte and platelet behaviour. This review summarises various approaches to measure and interpret PLAs and discusses potential experimental factors influencing platelet binding to leukocytes. Furthermore, we summarise insights gained from studies regarding the underlying mechanism of platelet-leukocyte interactions and discuss implications of these interactions in health and disease. PMID- 29461913 TI - Immunogenicity and safety of the first indigenously developed Indian tetravalent influenza vaccine (split virion) in healthy adults >= 18 years of age: A randomized, multicenter, phase II / III clinical trial. AB - This phase II / III clinical trial was conducted to evaluate the immunogenicity and safety of the Tetravalent Influenza vaccine (Split virion) I.P. (TetIV) developed indigenously in the country for the first time by M/s Cadila Healthcare Limited, India containing two influenza A and two influenza B strains, one of each, Yamagata (B/Phuket) and Victoria (B/Brisbane) lineage and also compare it to that of an licensed seasonal Trivalent Influenza vaccine (TriIV) of Sanofi Pasteur India Private Limited, containing the two influenza A and only the Yamagata lineage (B/Phuket) strain. Three hundred and fifty subjects of either sex, aged more than 18 years of age, were randomized in a 1:1 ratio to receive either the TetIV or TriIV. Immunogenicity assessments (antibody against A/H1N1, A/H3N2, B/Phuket and B/Brisbane) were done by Haemagglutination Inhibition assay at baseline and 21 d after vaccination. Solicited (local and systemic) and unsolicited adverse events were recorded for up to 42 d following vaccination. The TetIV was found to fulfill the criteria set by the European and the US regulatory authorities and WHO guidance on the requirements of clinical data for licensure of seasonal inactivated influenza vaccines. The seroconversion rates with TetIV were 93.5% for A/H1N1, 90.0% for A/H3N2, 70.0% for B/Phuket and 82.9% for B/Brisbane strain. There was no significant difference in the seroconversion and seroprotection rates at day 21 for A/H1N1, A/H3N2 and B/Phuket in the two groups while the TetIV was superior to the TrivIV for the seroconversion and the seroprotection rate for the B/Brisbane strain (Victoria lineage). Both the vaccines were well tolerated by all the study participants; addition of the fourth strain in the TetIV did not compromise the safety as compared to TriIV. The most common systemic adverse event reported in both the groups was headache followed by fever. PMID- 29461914 TI - Comparison of Open Versus Laparoscopic Versus Hand-Assisted Laparoscopic Nephroureterectomy: A Systematic Review and Meta-Analysis. AB - BACKGROUND: A systematic analysis of the evidence regarding oncological, perioperative and postoperative outcomes of open nephroureterectomy (ONU), laparoscopic nephroureterectomy (LNU), and hand-assisted laparoscopic nephroureterectomy (HALNU) was designed. METHODS: The summarized data were abstracted from 52 original research articles representing 19,195 patients. PubMed/Medline, Scopus, Google Scholar, EMBASE, and the Cochrane Library were reviewed in March 2017, following PRISMA framework. A total of 52 publications were selected for inclusion. The primary outcomes were 2- and 5-year cancer specific survival (CSS) rate, overall survival (OS) rate, and recurrence-free survival (RFS) rate. The secondary outcomes were operative time, lengths of hospitalization period, estimated blood loss, transfusions, major Clavien complication rate, metastasis rate, bladder recurrence rate, and positive surgical margin. RESULTS: On comparing LNU versus ONU and HALNU versus ONU, no significant differences between the 5-year CSS rate (P = .25, P = .39), OS rate (P = .06, P = .46), and RFS rate (P = .85, P = .73) were found. On comparing LNU versus ONU and HALNU versus ONU during a 2-year follow-up period, the following were found: CSS rate (P = .61, P = .04) and OS rate (P = .33, P = .19). There were no significant differences between the LNU versus ONU and HALNU versus ONU rates, regarding bladder recurrence (P = .12, P = .85) and metastasis rate (P = .07, P = .27). Significant higher operative time (P = .01, P = .0004), lower length of hospitalization period (P < .001, P < .001), and estimated blood loss (P = .0004, P < .001) were found in comparison to that of LNU versus ONU and HALNU versus ONU. CONCLUSION: Both LNU and HALNU had comparable oncological and better perioperative and postoperative outcomes, when compared with ONU. PMID- 29461915 TI - A novel method for automated assessment of megakaryocyte differentiation and proplatelet formation. AB - Transfusion of platelet concentrates represents an important treatment for various bleeding complications. However, the short half-life and frequent contaminations with bacteria restrict the availability of platelet concentrates and raise a clear demand for platelets generated ex vivo. Therefore, in vitro platelet generation from megakaryocytes represents an important research topic. A vital step for this process represents accurate analysis of thrombopoiesis and proplatelet formation, which is usually conducted manually. We aimed to develop a novel method for automated classification and analysis of proplatelet-forming megakaryocytes in vitro. After fluorescent labelling of surface and nucleus, MKs were automatically categorized and analysed with a novel pipeline of the open source software CellProfiler. Our new workflow is able to detect and quantify four subtypes of megakaryocytes undergoing thrombopoiesis: proplatelet-forming, spreading, pseudopodia-forming and terminally differentiated, anucleated megakaryocytes. Furthermore, we were able to characterize the inhibitory effect of dasatinib on thrombopoiesis in more detail. Our new workflow enabled rapid, unbiased, quantitative and qualitative in-depth analysis of proplatelet formation based on morphological characteristics. Clinicians and basic researchers alike will benefit from this novel technique that allows reliable and unbiased quantification of proplatelet formation. It thereby provides a valuable tool for the development of methods to generate platelets ex vivo and to detect effects of drugs on megakaryocyte differentiation. PMID- 29461916 TI - Outpatient Management of Fever and Neutropenia in Adults Treated for Malignancy: American Society of Clinical Oncology and Infectious Diseases Society of America Clinical Practice Guideline Update. AB - Purpose To provide an updated joint ASCO/Infectious Diseases Society of American (IDSA) guideline on outpatient management of fever and neutropenia in patients with cancer. Methods ASCO and IDSA convened an Update Expert Panel and conducted a systematic review of relevant studies. The guideline recommendations were based on the review of evidence by the Expert Panel. Results Six new or updated meta analyses and six new primary studies were added to the updated systematic review. Recommendation Clinical judgment is recommended when determining which patients are candidates for outpatient management, using clinical criteria or a validated tool such as the Multinational Association of Support Care in Cancer risk index. In addition, psychosocial and logistic considerations are outlined within the guideline. The panel continued to endorse consensus recommendations from the previous version of this guideline that patients with febrile neutropenia receive initial doses of empirical antibacterial therapy within 1 hour of triage and be monitored for >= 4 hours before discharge. An oral fluoroquinolone plus amoxicillin/clavulanate (or clindamycin, if penicillin allergic) is recommended as empirical outpatient therapy, unless fluoroquinolone prophylaxis was used before fever developed. Patients who do not defervesce after 2 to 3 days of an initial, empirical, broad-spectrum antibiotic regimen should be re-evaluated and considered as candidates for inpatient treatment.

PMID- 29461918 TI - Feasibility of a Video-Based Advance Care Planning Website to Facilitate Group Visits among Diverse Adults from a Safety-Net Health System. AB - BACKGROUND: Primary care providers in safety-net settings often do not have time to discuss advance care planning (ACP). Group visits (GV) may be an efficient means to provide ACP education. OBJECTIVES: To assess the feasibility and impact of a video-based website to facilitate GVs to engage diverse adults in ACP. DESIGN: Feasibility pilot among patients who were >=55 years of age from two primary care clinics in a Northern California safety-net setting. Participants attended two 90-minute GVs and viewed the five steps of the movie version of the PREPARE website ( www.prepareforyourcare.org ) concerning surrogates, values, and discussing wishes in video format. Two clinician facilitators were available to encourage participation. MEASUREMENTS: We assessed pre-to-post ACP knowledge, whether participants designated a surrogate or completed an advance directive (AD), and acceptability of GVs and PREPARE materials. RESULTS: We conducted two GVs with 22 participants. Mean age was 64 years (+/-7), 55% were women, 73% nonwhite, and 55% had limited literacy. Knowledge improved about surrogate designation (46% correct pre vs. 85% post, p = 0.01) and discussing decisions with others (59% vs. 90%, p = 0.01). Surrogate designation increased (48% vs. 85%, p = 0.01) and there was a trend toward AD completion (9% vs. 24%, p = 0.21). Participants rated the GVs and PREPARE materials a mean of 8 (+/-3.1) on a 10 point acceptability scale. CONCLUSIONS: Using the PREPARE movie to facilitate ACP GVs for diverse adults in safety net, primary care settings is feasible and shows potential for increasing ACP engagement. PMID- 29461920 TI - A Randomized Controlled Trial for Veterans with PTSD and Substance Use Disorder: Creating Change versus Seeking Safety. AB - BACKGROUND: Posttraumatic stress disorder (PTSD) and substance use disorder (SUD) co-occur in military veterans and other populations. OBJECTIVE: To conduct a randomized controlled trial to compare a new past-focused treatment (Creating Change; CC), to a well-established, evidence-based present-focused treatment for PTSD/SUD (Seeking Safety; SS), on symptoms of both disorders. CC guides patients to process the past through exploration of PTSD/SUD life themes and memories whereas SS focuses on coping skills in the present. METHODS: Fifty-two male and female veterans with current PTSD/SUD were randomized (n = 26 per treatment) and assessed at baseline, end-of-treatment and 3-month follow-up. They received 17 individual one-hour sessions. RESULTS: Intent-to-treat analyses indicated that both conditions improved over time, with no difference between conditions, on PTSD, alcohol use, and drug use (our primary outcomes) as well as mental health symptoms, quality of life, self-efficacy, and SUD cognitions. Effect sizes were medium except for alcohol use, which was large. Change over time reflected improvement from baseline to end-of-treatment, with gains sustained at follow-up, although alcohol use showed continued improvement from end-of-treatment to follow up. Both treatments evidenced a strong safety profile; and attendance, alliance, and treatment satisfaction were also very strong. Conclusions/importance: CC has promise as a PTSD/SUD therapy with strong public health relevance and the potential to fill important gaps in the field. We used minimal exclusionary criteria to obtain a real-world sample, which was severe-predominantly substance dependent with chronic PTSD and additional psychiatric diagnoses. Future research is warranted, especially on nonveteran samples and treatment mechanisms of action. PMID- 29461919 TI - Persistence of immune response to an adjuvanted varicella-zoster virus subunit vaccine for up to year nine in older adults. AB - BACKGROUND: In adults aged >=60 years, two doses of the herpes zoster subunit vaccine (HZ/su; 50 ug varicella-zoster virus glycoprotein E [gE] and AS01B Adjuvant System) elicited humoral and cell-mediated immune responses persisting for at least six years. We assessed immunogenicity nine years post-initial vaccination. METHODS: This open extension study (NCT02735915) followed 70 participants who received two HZ/su doses in the initial trial (NCT00434577). Blood samples to assess the cellular (intracellular cytokine staining) and humoral (ELISA) immunity were taken at year nine post-initial vaccination. RESULTS: Participants' mean age at dose 1 was 72.3 years. The fold increases over pre-vaccination in the mean frequency of gE-specific CD4+ T-cells expressing >=2 activation markers plateaued from year four post-dose 1 until year nine. Anti-gE antibody geometric mean concentrations plateaued and remained above pre vaccination levels from year four onwards. Immunogenicity at year nine was similar across age strata (60-69, >=70 years) and confirmed statistical prediction model results using data for up to year six. Further modeling using all data up to year nine predicted immune responses would remain above the pre vaccination level up to year 15. CONCLUSION: In adults aged >=60 years, HZ/su induced immunogenicity remained above pre-vaccination levels for at least nine years post-initial vaccination. SUMMARY: After vaccination with HZ/su, both cell mediated and humoral immunity remained above pre-vaccination levels up to year 9 regardless of age group. Immune responses are predicted to remain above baseline up to 15 years post initial vaccination. PMID- 29461921 TI - Porous orbital implant after enucleation in retinoblastoma patients: indications and complications. AB - This study aims to identify risk factors associated with complications in retinoblastoma patients following primary and secondary enucleations with porous implant placement. A retrospective case-control study was performed between 2010 and 2015. Data pertaining to subjects' demographics, medical history, clinical, and pathological findings, implant characteristics and complications were collected. The analysis included 103 eyes of 101 patients age 27.8 +/- 21.9 months undergoing enucleation for retinoblastoma. Postoperatively, 19/103 (18%) eyes developed exposure, extrusion, or hematoma requiring subsequent surgery. Exposure was the most common postoperative complication (12/19, 63%). Age at enucleation 24 months or younger, Hispanic ethnicity, female gender, and intravenous chemotherapy prior to enucleation were associated with increased odds of implant complications. In contrast, patients who were given intravitreal melphalan (IM), subtenons carboplatin (SC), or external beam radiation therapy (EBRT) did not demonstrate an increased risk of complications. In this cohort of retinoblastoma patients undergoing primary or secondary enucleation with porous implants, implant exposure was the most common postoperative complication. Our findings suggest that female gender, Hispanic ethnicity, age at enucleation 24 months or younger, and intravenous chemotherapy prior to enucleation may increase the risk of complications. PMID- 29461922 TI - A fishy eyelid injury. AB - A 9-year-old girl was reviewed by a tertiary ophthalmology service after being hit in her right upper eyelid by a fish whilst swimming. Initial wound exploration demonstrated fish scales in the wound. She was first treated conservatively with washout of the 5-mm wound and was discharged with oral ciprofloxacin. Five days later, the patient re-presented with a worsened ptosis due to periorbital swelling. Ultrasound of the upper lid demonstrated a foreign body in the upper lid. The patient was taken to theatre and, with the assistance of intraoperative ultrasound, the jaws of a needle fish were removed from the upper lid. The case highlights the importance of ultrasound and its intraoperative utility in cases of trauma and a suspicion of retained foreign bodies as well as the potential danger of fish injuries off the West Australian coast. PMID- 29461923 TI - Disquisition on the interaction of ibuprofen-Zn(II) complex with calf thymus DNA by spectroscopic techniques and the use of Hoechst 33258 and Methylene blue dyes as spectral probes. AB - The interaction between ibuprofen-Zn(II) complex and calf thymus DNA in physiological buffer (pH 7.4) was studied with the use of Hoechst 33258 and methylene blue dyes as spectral probes by multi-spectroscopic techniques, and viscosity measurements. It was found that ibuprofen-Zn(II) complex molecules could bind with DNA via groove binding mode as evidenced by: i- DNA binding constant (Kb = (1.00 +/- 0.2) * 104 M-1) from Spectrophotometric studies of the interaction of ibuprofen-Zn(II) complex with DNA is comparable to groove binding drugs. ii- Absorption Spectra of Competitive interaction of ibuprofen-Zn(II) complex and Hoechst 33258 with DNA exhibited the reverse process, The results suggested that interaction of the ibuprofen-Zn(II) complex with calf thymus DNA, is similar to Hoechst 33258 interaction with calf thymus DNA (This was verified by the following fluorescence study). iii- Competitive fluorimetric studies with Hoechst 33258 have shown that ibuprofen-Zn(II) complex exhibit the ability of this complex to displace with DNA-bounded Hoechst 33258, indicating that it binds to DNA in strong competition with Hoechst 33258 for the groove binding. iv- There is no significantly change in the fluorescence intensity of the MB-DNA system upon adding the ibuprofen-Zn(II) complex, indicate that MB molecules are not released from the DNA helix after addition of the ibuprofen-Zn(II) complex and are indicative of a non-intercalative mode of binding. v- Small changes in DNA viscosity in the presence of ibuprofen-Zn(II) complex, indicating weak link to DNA, which is consistent with DNA groove binding. As well as, induced CD spectral changes, and the docking results revealed that groove mechanism is followed by ibuprofen-Zn(II) complex to bind with DNA. PMID- 29461924 TI - Controlling alpha for mixed effects models for repeated measures. AB - Mixed Effects Models for Repeated Measures (MMRM) is often used in clinical trials with longitudinal data. However, there has not been an in-depth examination available on how investigators can implement interim analysis while also controlling the overall alpha for clinical trials under an MMRM analysis framework. Statistical independence among measurements, which is often assumed in group sequential testing (GST), is not valid under an MMRM framework due to the correlations induced by longitudinal within-subject measurements. Therefore, methods associated with GST derived under independence need to be adjusted accordingly. While these correlations can be estimated from the study data, regulatory agencies may not accept results based on these estimated correlations since there is no guarantee that the overall alpha is strongly controlled. In this article, we propose a new AC-Hybrid-approach for controlling the overall alpha. The AC-Hybrid-approach has two key attributes. First, we apply the MMRM analysis framework on all available data at every analysis timepoint. Second, we use complete-case information fractions to derive the group sequential stopping boundaries. We prove that the overall alpha is controlled regardless of the correlations among within-subject measurements. We also show the impact of this approach on the alpha and the power through examples. PMID- 29461925 TI - Negative Affect Intensity and Hostility in Individuals With Alcohol Use Disorder With or Without Posttraumatic Stress Disorder. AB - OBJECTIVE: Negative affect intensity and hostility have both been implicated in alcohol use disorders (AUD) and posttraumatic stress disorder (PTSD) when they occur separately, but neither have been compared or explored among those with comorbid AUD and PTSD. This study is a secondary analysis designed to compare levels of negative affect intensity and hostility among those with AUD to those with comorbid AUD and PTSD. METHODS: Participants (n = 113) were recruited from the placebo-controlled groups of two distinct 12-week clinical trials (NCT00342563 and NCT00744055). The Short Affect Intensity Scale and Buss-Durkee Hostility Inventory were administered at weeks 0, 4, 8, and 12 to all study participants to assess negative affect intensity and hostility levels, respectively. RESULTS: Individuals with comorbid AUD and PTSD showed significantly higher levels of negative affect intensity and hostility than individuals with AUD only. These levels remained relatively stable over the course of the study in spite of all study participants showing clinically significant improvements in AUD severity and PTSD symptomatology (for those with dual diagnosis). CONCLUSIONS: Our results indicate that individuals with comorbid AUD and PTSD have higher levels of negative affect and higher levels of hostility compared to individuals with AUD alone. In addition, these heightened levels of negative affect intensity and hostility appear to function somewhat independently of diagnosis severity and symptomatology improvement. To our knowledge, this is the first study to compare negative affect intensity and hostility levels between individuals with AUD alone and those with comorbid AUD and PTSD. PMID- 29461926 TI - The relationship between social status and the components of agency. AB - Building on the two fundamental dimensions of social judgment distinguishing communion from agency, the purpose of the present work was to show that the strength of the relationship between social status and agency depends on specific components at issue: assertiveness, competence, and effort. Four experimental studies were conducted using two complementary paradigms. In Studies 1 and 2, we manipulated social status, and participants had to rate the target on competence, assertiveness, and effort. In Studies 3 and 4, we reversed the design. Results consistently showed that social status was primarily related to assertiveness, somewhat related to competence, and only slightly related to effort. The present research provides a better understanding of how the dimensions of social judgment are used to explain differences in social status. PMID- 29461927 TI - Event-Based Conformity Versus Regression to the Mean: A Comment on Kim and Hommel (2015). PMID- 29461928 TI - Comparison of Clinical Isolates of Aeromonas from Singapore and Malaysia with Regard to Molecular Identification, Virulence, and Antimicrobial Profiles. AB - OBJECTIVE: The objective of this study was to examine the species distribution, genetic relatedness, virulence gene profiles, antimicrobial sensitivities, and resistance gene distribution of clinical Aeromonas strains from Singapore and Malaysia. METHODS: A total of 210 Aeromonas clinical isolates were investigated: 116 from Singapore General Hospital and 94 archived clinical isolates from University of Malaya Medical Center, Malaysia. The isolates were genetically identified based on the gcat gene screening and the partial sequences of the rpoD housekeeping gene. Genetic relatedness, distribution of 15 virulence genes and 4 beta-lactamase resistance genes, and susceptibility patterns to 11 antimicrobial agents were compared. RESULTS: Of the 210 Aeromonas isolates, A. dhakensis-94 (45%) was the dominant species in Singapore and Malaysia. Species composition was similar and enterobacterial repetitive intergenic consensus-PCR did not show genetic relatedness between strains from the two countries. Of the 15 virulence genes, A. dhakensis and A. hydrophila harbored the most compared with other species. Different combinations of 9 virulence genes (exu, fla, lip, eno, alt, dam, hlyA, aexU, and ascV) were present in A. dhakensis, A. hydrophila, and A. veronii from both the countries. Distribution of virulence genes was species and anatomic site related. Majority (>80%) of the strains were susceptible to all antimicrobial agents tested, except amoxicillin and cephalothin. A. dhakensis strains from Malaysia significantly harbored the cphA gene compared with A. dhakensis from Singapore. Multidrug resistance was mostly detected in strains from peritoneal fluids of dialysis patients. CONCLUSION: This study revealed A. dhakensis as the dominant species isolated in both geographic regions, and that it carried a high number of virulence genes. It also highlights the geographic related differences of virulence gene distribution and antimicrobial resistance profiles of clinical Aeromonas strains from Singapore and Malaysia. PMID- 29461929 TI - Impact of the Antibiotic Stewardship Program on Prevention and Control of Surgical Site Infection during Peri-Operative Clean Surgery. AB - BACKGROUND: Surgical site infections (SSIs) are the leading cause of hospital acquired infections and are associated with substantial healthcare costs, with increased morbidity and mortality. To investigate the effects of the antibiotic stewardship program on prevention and control of SSI during clean surgery, we investigated this situation in our institution. PATIENTS AND METHODS: We performed a quasi-experimental study to compare the effect before and after the antibiotic stewardship program intervention. During the pre-intervention stage (January 1, 2010 through December 31, 2011), comprehensive surveillance was performed to determine the SSI baseline data. In the second stage (January 1, 2012 through December 31, 2016), an infectious diseases physician and an infection control practitioner identified the surgical patients daily and followed up on the duration of antimicrobial prophylaxis. RESULTS: From January 1, 2010 to December 31, 2016, 41,426 patients underwent clean surgeries in a grade III, class A hospital. The rate of prophylactic antibiotic use in the 41,426 clean surgeries was reduced from 82.9% to 28.0% after the interventions. The rate of antibiotic agents administered within 120 minutes of the first incision increased from 20.8% to 85.1%. The rate at which prophylactic antimicrobial agents were discontinued in the first 24 hours after surgery increased from 22.1% to 60.4%. Appropriate antibiotic selection increased from 37.0% to 93.6%. Prophylactic antibiotic re-dosing increased from 3.8% to 64.8%. The SSI rate decreased from 0.7% to 0.5% (p < 0.05). The pathogen detection rate increased from 16.7% up to 41.8% after intervention. The intensity of antibiotic consumption reduced from 74.9 defined daily doses (DDDs) per 100 bed-days to 34.2 DDDs per 100 bed-days after the interventions. CONCLUSION: Long-term and continuous antibiotic stewardship programs have important effects on the prevention and control of SSI during clean surgery. PMID- 29461930 TI - The Role of Cannabinoid Receptor 1 in the Immunopathology of Respiratory Syncytial Virus. AB - Endocannabinoid system plays an important role in pathophysiologic processes such as immune functions and impacts on disease severity. Our previous study showed that cannabinoid receptor 2 (CB2) affects clinical course of respiratory syncytial virus (RSV) infection. In this study, we investigated the role of cannabinoid receptor 1 (CB1) in RSV immunopathology and its therapeutic potential in mice model. To study the role of CB1 receptors in the immunopathology of RSV, CB1 was blocked daily with AM281 as a selective antagonist in Balb/c mice and were infected by intranasal inoculation of RSV-A2 24 h following the first dose of antagonist administration. The potential pharmacological therapeutic effects of cannabinoid receptor activation during RSV infection were studied using JZL184 as a selective indirect agonist, 24 h after infection. Mice were sacrificed on day 5 after infection and experimental analyses were performed to study the CB1 receptor expression, airway immune cell influx, cytokine/chemokine secretion, lung histopathology, and viral load. RSV infection of airways significantly induced the expression of CB1 receptors in lung cells of mice. Blockade of CB1 receptors using AM281 enhanced immune cell influx and cytokine/chemokine production, and aggravated lung pathology. Activation of cannabinoid receptors using JZL184 decreased immune cell influx and cytokine/chemokine production, and alleviated lung pathology. This study and our previous finding indicated that endocannabinoid signaling regulates the inflammatory response to RSV infection, and is a potential therapeutic candidate for alleviation of RSV-associated immunopathology. PMID- 29461931 TI - Use of Cold Fluids in Postcardiac Arrest Therapeutic Hypothermia: A Safety Analysis. AB - Therapeutic hypothermia (TH) has been part of the standard care of postresuscitation patients for more than a decade. Multiple cooling methods are available, including the administration of cold intravenous (IV) fluids. Although this method is widely used, the safety of administration of large volumes of cold IV fluids has not been clearly demonstrated in the literature, and recent evidence points to potential deleterious effects associated with administration of large IV fluid volumes. We conducted a retrospective cohort study among patients who have been treated with TH after cardiac arrest between November 2011 and November 2013 at a tertiary care hospital in Sherbrooke, Quebec, Canada. The primary outcome was the effect of IV fluid quantity on the 28-day survival rate. We reviewed 29 cases, with a total 28-day surviving rate of 51.7%. After adjusting for confounding variables, 28-day surviving rate was not significantly associated with the amount of fluids administrated (odds ratio = 1.034; confidence interval 95% [0.741-1.464]; p = 0.85). The amount of fluids did not influence the variation of the pulmonary component of the sequential organ failure assessment score between days 1 and 3 (rho = -0.2, p = 0.34). Despite a small sample of patients, cold IV fluids in TH appear safe in the postcardiac arrest population. These findings should be reproduced in a larger, prospective study. PMID- 29461932 TI - Clinical Outcomes From a 10-Week Follow-Up Psychoeducational Program for Dual Diagnosis. AB - BACKGROUND: Dual diagnosis covers a broad spectrum of mental health and substance misuse conditions occurring concurrently (NICE, 2016 ). Its manifestation is complex and, as such, the disorder is recognized as influencing adherence to prescribed medication and service engagement and has a worse prognosis than substance use and mental health conditions occurring independently. AIMS: To determine the effectiveness of psychoeducational group therapy in a sample of dual diagnosis patients. METHODS: Patients who met the Diagnostic and Statistical Manual of Mental Disorders-IV Axis 1 criteria for serious mental illness and current substance misuse were approached to take part in a psychoeducational program. Those who consented were assessed at baseline and end point using measures of psychiatric symptomology, psychological well-being, and substance use patterns with the following scales: the Brief Psychiatric Rating Scale, the Hospital Anxiety and Depression Rating Scale, the Maudsley Addiction Profile Scale, and the Warwick-Edinburgh Mental Wellbeing Scale. RESULTS: Fifty-one patients completed the program, while 29 dropped out after initial assessment. Between baseline and follow-up, there was a decline in the number of participants using alcohol, cannabis, cocaine, amphetamine, illicit benzodiazepines and methadone. However, the number of participants using heroin remained constant. The mean amount of substances used was not reduced over the study period except in the case of alcohol. Overall improvements in symptomology and psychological well-being were observed. DISCUSSION: Mental health services should focus on integrated approaches via multimodal treatment interventions that encapsulate harm reduction and educational initiatives: Despite the modest sample, the findings have emphasized the importance of a broad range of treatment approaches delivered within a unitary delivery system. PMID- 29461933 TI - Identifying Priorities for Aging Policies in Two Portuguese Communities. AB - The aging population has an impact on health, social, and economic issues in regard to individuals, communities, and organizations. The challenge for local policies in response to aging is to create sufficient resources to meet the population's needs, wishes, and rights as people age. Active aging constitutes one of the guiding perspectives on policies. Taking into account the local governance perspective, the Model for Aging Local Policies Analysis (MALPA) was created in order to convert the active aging paradigm into a practical approach, as a technique to evaluate and analyze local aging policies. In this research, the MALPA instrument was applied in two Portuguese communities (Coruche and Oeiras). The objective was to identify the intervention priorities of aging policies in both communities, determining whether the instrument can facilitate the development of proposals for the improvement of local aging policies. It was possible to evaluate the communities and programs, identifying the least appropriate policy actions regarding the intervention priorities. The results allowed us to identify 10 priorities about collaborative governance, involvement of the elderly in the policy-making process, lifelong learning, economic hardship, policies for all ages, isolated vulnerable and fragile groups, intergenerational contacts, safety in all policies, labor opportunities, and conditions and transport network improvement. PMID- 29461934 TI - Risk and Protective Factors for Self-Harm in a Population-Based Sample of Transgender Youth. AB - This study sought to identify factors distinguishing transgender/gender non conforming (GNC) adolescents across three groups: no self-harm, non-suicidal self injury (NSSI) only, and NSSI and suicide attempt (NSSI + SA). Data were from the 2016 Minnesota Student Survey. The final analytic sample included 1,635 transgender/GNC students in grades 9 and 11. Logistic regression analyses determined factors that best distinguished transgender/GNC students who reported self-harm (NSSI only or NSSI + SA) from those who reported no self-harm, and transgender/GNC adolescents who reported NSSI + SA from those who reported NSSI only. Final models were developed over 3 stages of analysis that tested associations of variables within risk factor, protective factor, and health-risk behavior domains to self-harm. Over half (51.6%) of transgender/GNC adolescents reported past-year self-harm behavior. Factors that consistently distinguished transgender/GNC youth who reported self-harm from those who reported no self-harm included reports of a mental health problem, depression, running away from home, and substance use (alcohol or marijuana use). Factors that distinguished the NSSI + SA group from the NSSI only group were reports of a mental health problem, physical or sexual abuse, relationship violence, bullying victimization, less parent connectedness, lower grades, lower levels of perceived school safety, and running away from home. Clinicians and school personnel need to be prepared to address risk factors and enhance protective factors that may reduce the likelihood this population of vulnerable youth will engage in NSSI and/or attempt suicide. PMID- 29461935 TI - Menstrual Cycle Effects on Mental Health Outcomes: A Meta-Analysis. AB - The premenstrual phase of cycle has long been associated with a constellation of health symptoms for women. However, there has been no recent quantitative review of severe mental health outcomes as a function of the menstrual cycle. We examine cycle influences on completed suicides, suicide attempts, suicidal ideation, and psychiatric admissions, and contrast these with non-suicide deaths. We conducted a meta-analysis of 32 papers, with an N of 3,791. We find 26% greater risk of suicide deaths, 17% greater risk of suicide attempts, and 20% greater risk of psychiatric admissions at menstruation. We also observe 13% greater risk of psychiatric admissions during the premenstrual phase. Suicidal ideation was unrelated to the stage of menstrual cycle. Available evidence finds serious and consequential mental health outcomes in the menstrual and premenstrual phases. PMID- 29461936 TI - Quantification of trunk and android lean mass using dual energy x-ray absorptiometry compared to magnetic resonance imaging after spinal cord injury. AB - OBJECTIVE: To determine whether dual energy x-ray absorptiometry (DXA) compared to magnetic resonance imaging (MRI) may accurately quantify trunk lean mass (LM) after chronic spinal cord injury (SCI) and to investigate the relationships between trunk LM, visceral adiposity, trunk fat mass and basal metabolic rate (BMR). DESIGN: Cross-sectional design and correlational analysis. SETTING: Research setting in a medical center. PARTICIPANTS: Twenty-two men with motor complete paraplegia (n = 14; T4-T11) and tetraplegia (n = 8; C5-C7) were recruited as part of a clinical trial. INTERVENTIONS: Not applicable. OUTCOME MEASURES: Trunk and android LM were measured using DXA. The volume of six trunk muscle groups were then measured using MRI to quantify trunk LM-MRI. Subcutaneous and visceral adipose tissue (VAT) cross-sectional areas were also measured using MRI. After overnight fast, BMR was evaluated using indirect calorimetry. RESULTS: Trunk LM-DXA (24 +/- 3.3 kg) and android LM-DXA (3.6 +/- 0.7 kg) overestimated (P < 0.0001) trunk LM-MRI (1.7 +/- 0.5 kg). Trunk LM-MRI = 0.088* log (trunk LM-DXA) 0.415; r2=0.29, SEE= 0.44 kg, P = 0.007. Trunk LM-MRI = 1.53* android LM-DXA + 0.126; r2=0.26, SEE= 0.21 kg, P = 0.018. Percentage trunk LM-MRI was inversely related to VAT (r=-0.79, P < 0.0001) and trunk fat mass (r=-0.83, P < 0.001). Only trunk LM-DXA was related to BMR (r = 0.61, P = 0.002). Persons with tetraplegia have 13% smaller trunk muscle cross-sectional areas (P = 0.036) compared to those with paraplegia. CONCLUSIONS: Trunk LM-DXA and android LM-DXA overestimated trunk LM-MRI. Percentage trunk LM-MRI, but not LM-DXA, was inversely related to trunk central adiposity. The findings highlight the importance of exercising trunk LM to attenuate cardio-metabolic disorders after SCI. PMID- 29461937 TI - Singular stochastic control model for algae growth management in dam downstream. AB - A stochastic control model for finding an ecologically sound, fit-for-purpose dam operation policy to suppress bloom of attached algae in its downstream is presented. A singular exactly solvable and a more realistic regular-singular cases are analysed in terms of a Hamilton-Jacobi-Bellman equation. Regularity and consistency of the value function are analysed and its classical verification theorem is established. Practical implications of the mathematical analysis results are discussed focusing on parameter dependence of the optimal controls. An asymptotic analysis with a numerical computation reveals solution behaviour of the Hamilton-Jacobi-Bellman equation near the origin, namely at the early stage of algae growth.

AB - This study describes the development of a self-reported psychosocial distress screening tool for a general medical population and criteria to predict the need for psychosocial intervention. The objectives were to develop criteria to determine which patients need in-person screening and establish criteria identifying patients who are more likely to require psychosocial interventions. The outcomes have bearing on reducing initial psychosocial screening workload for medical social workers in high volume medical settings. Furthermore, a criterion for scoring the self-reported tool can predict which patients will need further social work intervention. The results suggest criteria are a score on the adapted Distress Thermometer of five or greater, at least two negative emotions, and a lack of health insurance. The optimal criterion identified 36% (446/1228) of patients in need of in-person screening with the remaining 64% (782/1228) screened low risk through the tool, representing a significant workload reduction.

AB - OBJECTIVE: Training programs exist that prepare college students, faculty, and staff to identify and support students potentially at risk for suicide. Kognito is an online program that trains users through simulated interactions with virtual humans. This study evaluated Kognito's effectiveness in preparing users to intervene with at-risk students. PARTICIPANTS: Training was completed by 2,727 university students, faculty, and staff from April, 2014 through September, 2015. METHODS: Voluntary and mandatory participants at a land-grant university completed Kognito modules designed for higher education, along with pre- and post assessments. RESULTS: All modules produced significant gains in reported Preparedness, Likelihood, and Self-Efficacy in intervening with troubled students. Despite initial disparities in reported abilities, after training participants reported being similarly capable of assisting at-risk students, including LGBTQ and veteran students. CONCLUSIONS: Kognito training appears to be effective, on a large scale, in educating users to act in a facilitative role for at-risk college students.

AB - There is an urgent need for the discovery of effective new antimicrobial agents to combat the rise of bacterial drug resistance. High-throughput screening (HTS) in whole-animal infection models is a powerful tool for identifying compounds that show antibacterial activity and low host toxicity. In this report, we characterize the activities of four novel antistaphylococcal compounds identified from an HTS campaign conducted using Caenorhabditis elegans nematodes infected with methicillin-resistant Staphylococcus aureus (MRSA). The hit compounds included an N-hydroxy indole-1, a substituted melamine derivative-2, N substituted indolic alkyl isothiocyanate-3, and p-difluoromethylsulfide analog-4 of the well-known protonophore carbonyl cyanide m-chlorophenyl hydrazone. Minimal inhibitory concentrations (MICs) of the four compounds ranged from 2 to 8 MUg/ml against MRSA-MW2 and Enterococcus faecium and all were bacteriostatic. The compounds were mostly inactive against Gram-negative pathogens, with only 1 and 4 showing slight activity (MIC = 32 MUg/ml) against Acinetobacter baumanii. Compounds 2 and 3 (but not 1 or 4) were found to perturb MRSA membranes. In phagocytosis assays, compounds 1, 2, and 4 inhibited the growth of internalized MRSA in macrophages, whereas compound 3 showed a remarkable ability to clear intracellular MRSA at its MIC (p < 0.001). None of the compounds showed hemolytic activity at concentrations below 64 MUg/ml (p = 0.0021). Compounds 1, 2, and 4 (but not 3) showed synergistic activity against MRSA with ciprofloxacin, while compound 3 synergized with erythromycin, gentamicin, streptomycin, and vancomycin. In conclusion, we describe four new antistaphylococcal compounds that warrant further study as novel antibacterial agents against Gram-positive organisms.

AB - Advancing age is the biggest risk factor for development for the major life threatening diseases in industrialized nations accounting for >90% of deaths. Alzheimer's dementia (AD) is among the most devastating. Currently approved therapies fail to slow progression of the disease, providing only modest improvements in memory. Recently reported work describes mechanistic studies of J147, a promising therapeutic molecule previously shown to rescue the severe cognitive deficits exhibited by aged, transgenic AD mice. Apparently, J147 targets the mitochondrial alpha-F1-ATP synthase (ATP5A). Modest inhibition of the ATP synthase modulates intracellular calcium to activate AMP-activated protein kinase to inhibit mammalian target of rapamycin, a known mechanism of lifespan extension from worms to mammals. PMID- 29461943 TI - Is Low-Dose Radiation Exposure a Risk Factor for Atherosclerotic Disease? AB - Nontargeted late effects of radiation include an increased risk of cardiovascular disease, although this is still debatable in the context of low-dose radiation. Tinea capitis patients treated in childhood with X rays to induce scalp epilation received a low dose of radiation to their carotids. To better clarify this issue, we evaluated carotid atherosclerosis in a cohort of such patients treated in 1950 1963 in Portugal. A group of 454 individuals randomly chosen from previously observed Portuguese tinea capitis patients and a control group mainly composed of their spouses (n = 280) were enrolled. Cardiovascular risk factors such as waist circumference, body mass index, blood pressure and tobacco consumption, as well as biochemical measurements were obtained. Ultrasound imaging of carotid arteries for intima media thickness and stenosis evaluation were performed according to a standardized protocol. In comparison to the control group, the irradiated cohort members were significantly older, more frequently never smokers, hypertensive, and presented higher glycated hemoglobin and alkaline phosphatase levels. In addition, the irradiated cohort showed a higher frequency of carotid stenosis >=30% than the nonirradiated group (13.9% vs. 10.7%), although this was not significant ( P = 0.20). Stenosis was >=50% in 2.9% of the irradiated group and 0.4% of the nonirradiated group ( P = 0.02). Likewise, the frequency of intima media thickness >=1 mm was significantly higher in the irradiated group (16.8% vs. 10.7%; P = 0.02). Multivariate analysis, including other cardiovascular risk factors, showed that exposure to low-dose radiation increased the risk of carotid stenosis by >=50% [odds ratio (OR) = 8.85; P = 0.04] and intima media thickness by >=1 mm (OR = 1.82; P = 0.02). These findings confirm that low-dose exposure is a risk factor of carotid atherosclerotic disease.

AB - History A 21-year-old man with a history of abuse of multiple drugs and mild cognitive impairment who initially underwent treatment for excited delirium developed respiratory arrest shortly after admission and was successfully resuscitated. Unenhanced computed tomography (CT) of the head and neck and contrast material-enhanced CT of the chest, abdomen, pelvis, and complete spine were performed shortly after the initial treatment. Head and neck magnetic resonance (MR) imaging was performed 24 hours after admission. No other abnormalities were noted. There were no fractures, and there was no vascular injury in the head and neck region. The patient had no external neck injuries, congestion, or petechiae suggesting neck compression. He had no history of chronic or recurrent pain or skin rash. Urine testing was positive for cocaine, cannabis, and methamphetamine. Serum creatine kinase level was initially high (31 117 U/L [520 MUkat/L]; normal, 1000 U/L [16.7 MUkat/L]). Corrected calcium level was 2.22 mmol/L, and ionized calcium level was 1.09 mmol/L (lower end of the normal range). There was no acute renal failure at the initial phase, but serum creatinine levels reached 180 umol/L 24 hours after admission, and creatine kinase peaked at 61 000 U/L [1019 MUkat/L]. Urine was initially red, but the patient was not tested for myoglobinuria. PMID- 29461950 TI - Immediate Allergic Reactions to Gadolinium-based Contrast Agents.

AB - Chronic liver diseases often result in the development of liver fibrosis and ultimately, cirrhosis. Treatment strategies and prognosis differ greatly depending on the severity of liver fibrosis, thus liver fibrosis staging is clinically relevant. Traditionally, liver biopsy has been the method of choice for fibrosis evaluation. Because of liver biopsy limitations, noninvasive methods have become a key research interest in the field. Elastography enables the noninvasive measurement of tissue mechanical properties through observation of shear-wave propagation in the tissue of interest. Increasing fibrosis stage is associated with increased liver stiffness, providing a discriminatory feature that can be exploited by elastographic methods. Ultrasonographic (US) and magnetic resonance (MR) imaging elastographic methods are commercially available, each with their respective strengths and limitations. Here, the authors review the technical basis, acquisition techniques, and results and limitations of US- and MR-based elastography techniques. Diagnostic performance in the most common etiologies of chronic liver disease will be presented. Reliability, reproducibility, failure rate, and emerging advances will be discussed.

PMID- 29461957 TI - Disease activity and dropout in young persons with juvenile idiopathic arthritis in transition of care: a longitudinal observational study. AB - OBJECTIVES: Reaching a certain age, juvenile idiopathic arthritis (JIA) patients in paediatric care are transferred to adult care. An increased disease activity after transfer and increased dropout has been suggested, however, evidence is scarce. Our aim is to determine whether the process of transition is associated with increased disease-activity and dropout, and to identify associated factors. METHODS: During a 3-year prospective transition cohort study, paediatric patients (14-17yrs) were transferred to adult care. Paediatric (10-13yrs) and adult JIA patients (18-27yrs) were used as control groups. Demographic and disease-related items were obtained yearly. Non-parametric tests were used to compare differences between the groups and mixed models to evaluate disease activity over time, measured by JADAS27 and DAS28. Dropout was defined as not attending the clinic for 2 consecutive visits. RESULTS: Groups did not differ regarding baseline variables of subtype, gender, uveitis, ANA-, RF- or HLA B27-positivity and current or past DMARD use. Median disease activity was not different between groups during follow-up. Transfer was not associated with disease activity. Dropout rate was 12%, and was significantly higher in patients under transition (22%) compared with paediatric (3%) and adult care (10%). Patients who dropped out had significantly lower disease activity at baseline and were using less MTX, but did not differ regarding subtype, ANA, RF and HLA-B27. CONCLUSIONS: The process of transition in JIA is not associated with an increase in disease activity, however, this period carries a risk for drop out especially in patients with low disease activity. PMID- 29461958 TI - Gout in Duke Federico of Montefeltro (1422-1482): a new pearl of the Italian Renaissance. AB - The article examines the truthfulness of historical accounts claiming that Renaissance Duke Federico of Montefeltro (1422-1482) suffered from gout. By direct paleopathological assessment of the skeletal remains and by the philological investigation of historical and documental sources, primarily a 1461 handwritten letter by the Duke himself to his personal physician, a description of the symptoms and Renaissance therapy is offered and a final diagnosis of gout is formulated. The Duke's handwritten letter offers a rare testimony of ancient clinical self-diagnostics and Renaissance living-experience of gout. Moreover, the article also shows how an alliance between historical, documental and paleopathological methods can greatly increase the precision of retrospective diagnoses, thus helping to shed clearer light onto the antiquity and evolution of diseases. PMID- 29461959 TI - One year in review 2017: spondyloarthritis. AB - The term spondyloarthritis (SpA) represents a condition characterised by a broad spectrum of clinical manifestations, laboratory abnormalities and imaging features; in particular, SpA is an inflammatory condition in which both peripheral and axial joints might be affected. The majority of people with this disease have either psoriatic arthritis or axial spondyloarthritis, which includes ankylosing spondylitis. Less common subgroups are enteropathic SpA, which is associated with inflammatory bowel diseases (Crohn's disease and ulcerative colitis), reactive arthritis, which can occur in people following gastrointestinal or genitourinary infections and undifferentiated SpA, that does not meet the diagnostic criteria of the other subgroups at onset, but that may evolve to do so later. Very interestingly, much of the emerging data show how SpA, during its course, tends to associate with the development of some comorbidities; in particular, with cardiovascular diseases, diabetes mellitus, osteoporosis and depressive disorders. Healthcare professionals in non-specialist settings do not always recognise the signs and symptoms of SpA, particularly spinal symptoms, which may be mistakenly attributed to other causes of low back pain, thus leading to significant delays in diagnosis and treatment of the disease itself and of its related comorbidities, with consequent disease progression and disability, compromising the health-related quality of life of patients. In this paper we reviewed the literature of the past year (Medline search of articles published from 1st March 2016 to 28th February 2017) with the aim of approaching the spectrum of SpA from some different points of view, to try to give the reader an insight into this clinically challenging group of rheumatic pathologies.

AB - Detection of nuclei is an important step in phenotypic profiling of 1) histology sections imaged in bright field; and 2) colony formation of the 3-D cell culture models that are imaged using confocal microscopy. It is shown that feature-based representation of the original image improves color decomposition (CD) and subsequent nuclear detection using convolutional neural networks independent of the imaging modality. The feature-based representation utilizes the Laplacian of Gaussian (LoG) filter, which accentuates blob-shape objects. Moreover, in the case of samples imaged in bright field, the LoG response also provides the necessary initial statistics for CD using nonnegative matrix factorization. Several permutations of input data representations and network architectures are evaluated to show that by coupling improved CD and the LoG response of this representation, detection of nuclei is advanced. In particular, the frequencies of detection of nuclei with the vesicular or necrotic phenotypes, or poor staining, are improved. The overall system has been evaluated against manually annotated images, and the F-scores for alternative representations and architectures are reported.

AB - OBJECTIVE: We proposed and evaluated a method for correcting possible phase shifts provoked by the presence of ventricular premature contractions (VPCs) for a better assessment of T-wave alternans (TWA). Methods: First, we synthesized ECG signals with artificial TWA in the presence of different noise sources. Then, we assessed the prognostic value for sudden cardiac death (SCD) of the long-term average of TWA amplitude (the index of average alternans, ) in ambulatory ECG signals from congestive heart failure (CHF) and evaluated whether it is sensitive to the presence of VPCs. RESULTS: The inclusion of the phase correction after VPC in the processing always improved estimation accuracy of the under different noisy conditions and regardless of the number of the VPCs included in the sequence. It also presented a positive impact on the prognostic value of with increased hazard ratios (from 17% to 29%, depending of the scenario) in comparison to the noninclusion of this step. CONCLUSION: The proposed methodology for estimation, which corrects for the possible phase reversal on TWA after the presence of VPCs, represents a robust TWA estimation approach with a significant impact on the prognostic value of for SCD stratification in CHF patients. SIGNIFICANCE: An accurate TWA estimation has a potential direct clinical impact on noninvasive SCD stratification, allowing better identification of patients at higher risk and helping clinicians in adopting the most appropriate therapeutic strategy. PMID- 29461966 TI - Anxiety and perceived psychological stress play an important role in the immune response after exercise. AB - There are common pathways by which psychological stress and exercise stress alter immunity. However, it remains unknown whether psychological stress plays a role in the in vivo immune response to exercise. We examined the relationship between anxiety and perceived psychological stress reported before exercise and in vivo immunity after exercise using skin sensitisation with Diphenylcyclopropenone (DPCP). In a randomised design, sixty four, thoroughly familiarised, males completed widely used psychological instruments to assess state-anxiety and perceived psychological stress before exercise, and ran either 30 minutes at 60% (30MI) or 80% (30HI) V . O2peak, 120 minutes at 60% (120MI) V . O2peak or rested (CON) before DPCP sensitisation. Cutaneous recall to DPCP was measured as the dermal thickening response to a low-dose series DPCP challenge 4-weeks after sensitisation. After accounting for exercise (R2 = 0.20; P < 0.01), multiple regression showed that pre-exercise state-anxiety (STAI-S; DeltaR2 = 0.19; P < 0.01) and perceived psychological stress (DeltaR2 = 0.13; P < 0.05) were moderately associated with the DPCP response after exercise. The STAI-S scores before exercise were considered low-to-moderate in these familiarised individuals (median split; mean STAI-S of low 25 and moderate 34). Further examination showed that the DPCP response after exercise (30MI, 30HI or 120MI) was 62% lower in those reporting low vs. moderate state-anxiety before exercise (mean difference in dermal thickening: -2.6 mm; 95% CI: -0.8 to -4.4 mm; P < 0.01). As such, the results indicate a beneficial effect of moderate (vs. low) state-anxiety and perceived psychological stress on in vivo immunity after exercise. Moreover, correlations were of comparable strength for the relationship between physiological stress (heart rate training impulse) and the summed dermal response to DPCP (r = -0.37; 95% CI: -0.05 to -0.62; P = 0.01), and state-anxiety and the summed dermal response to DPCP (r = 0.39; 95% CI: 0.08 to 0.63; P < 0.01). In conclusion, state-anxiety and perceived psychological stress levels before exercise play animportant role in determining the strength of the in vivo immune response after exercise. These findings indicate a similar strength relationship for the level of state-anxiety prior to exercise and the level of physiological stress during exercise with the in vivo immune response after exercise. Future research is required to investigate exercise-immune responses in athletes, military personnel and others in physically demanding occupations experiencing higher levels of psychological stress than those reported in this study e.g. related to important competition, military operations and major life events. Nevertheless, the present findings support the recommendation that exercise scientists should account for anxiety and psychological stress when examining the immune response to exercise. PMID- 29461967 TI - Effects of lifelong training on senescence and mobilization of T lymphocytes in response to acute exercise. AB - BACKGROUND/PURPOSE: Ageing has profound impact on the immune system, mainly on T cells. However, it has been suggested that chronic exercise may delay immunosenescence. Master athletes represent an interesting sub-demographic group to test this theory since they maintain a high training frequency and load throughout life. The purpose of this study was to evaluate the effects of lifelong training on the senescence and mobilization of T lymphocytes in response to acute exercise. MATERIAL AND METHODS: Nineteen athletes who regularly participated in training and competitions for more than 20 years throughout their lives and a control group of 10 healthy individuals participated in this study. All subjects performed a progressive test to exhaustion on a cycle ergometer. Blood samples were obtained before (Pre), 10 min after the test (Post) and 1 h after the test (1h). Phenotypic study of peripheral blood T-cells was performed by flow cytometry. Genes of interest expression was done on T-cells purified by cell sorting. RESULTS: Master athletes had a lower percentage of senescent naive, central memory and effector memory CD8+ T-cells and senescent naive and effector memory CD4+ T-cells. Age had a positive effect on SLEC CD8+ T-cells and a negative effect on naive CD8+ T-cells. VO2max positively correlated with the proportion of naive CD4+ T-cells and negatively correlated with the percentage of total lymphocytes. No differences were founded for CD4+ and CD8+ T-cells and their subsets between master athletes and the control group at all times of measurement. No differences were observed in the CD45RA expressing effector memory cells (EMRA) for the various study conditions. The mRNA expression of the CCR7 gene for naive CD8+ T-cells and the Fas-L gene for effector-terminal CD8+ T cells was not different between masters and controls and did not change in response to the maximal protocol test. CONCLUSION: In conclusion, maintaining high levels of aerobic fitness during the natural course of aging may help prevent the accumulation of senescent T-cells. PMID- 29461968 TI - The Role of Exercise and Hyperlipidaemia in Breast Cancer Progression. AB - Exercise reduces the risk of breast cancer development and improves survival in breast cancer patients. However, the underlying mechanisms of this protective effect remain to be fully elucidated. It is unclear whether exercise can attenuate or modify the pro-tumour effects of obesity and related conditions, such as hyperlipidaemia. This review summarises how hyperlipidaemia and exercise contribute to or reduce breast cancer risk and progression, respectively, and highlights the possible mechanisms behind each. In particular, the effects of exercise and hyperlipidaemia on the immune microenvironment of tumours is analysed. The potential value of commonly investigated circulating factors as exercise-modulated, prognostic biomarkers is also discussed. We propose that exercise may alleviate some of the pro-tumorigenic effects of hyperlipidaemia through the reduction of blood lipid levels and modulation of cytokine release to induce beneficial changes in the tumour microenvironment. PMID- 29461969 TI - Toll like receptor expression induced by exercise in obesity and metabolic syndrome: A systematic review. AB - BACKGROUND: Obesity and metabolic syndrome are disorders that correlate with the activation of pro-inflammatory pathways and cytokine production, to which Toll like receptors (TLR) contribute. Exercise may act as an anti-inflammatory modulator, but there is no consensus about the role of the TLR in this tuning. The present styudy aims to systematically review the current evidence on exercise induced TLR regulation in animals and humans suffering from obesity and metabolic syndrome. METHODS: Pubmed and Scopus databases were searched for publications from 1990 to September 2015. Search terms included: "Toll like Receptor", "TLR", "exercise", "obesity", "diabetes", and "metabolic syndrome". Elegibility criteria comprised: randomized control trials, cross-sectional and cohort studies; human or animal models with metabolic syndrome; any type of exercise; TLR expression measurement in any tissue by a clearly reported technique. The quality of selected studies was assessed using a modified version of the Downs and Black Quality Assessment Checklist. Data of study design; population; exercise type, timing and training elements; measurement technique, tissue analyzed and main outcome were extracted and categorized to facilitate data synthesis. RESULTS: 17 studies were included, of which 11 publications obtained a high, 5 a moderate and 1 a low score for quality assessment. A total of 8 human studies were analyzed: 6 studies used endurance continuous or interval training protocols, 1 study resistance training and the remaining study was performed following a marathon race. Blood cells were analyzed in seven studies, of which four studies sampled peripheral blood mononuclear cells (PBMC), three analyzed whole blood and one study sampled skeletal muscle. Nine animal studies were included: 8 used endurance training and 1 acute aerobic exercise. A variety of tissues samples were explored such as PBMC, skeletal muscle, adipose, vascular and nervous tissue. Globally, the animal studies showed a marked tendency towards a down regulation of TLR2 and 4 expression accompagnied with, a reduced activation of nuclear factorkappaB (NF-kappaB) signaling and cytokine production, and an improvement in insulin sensitivity and body composition. CONCLUSION: While animal studies showed a marked tendency towards TLR2 and 4 down-regulation after chronic endurance exercise, the current evidence in human is not sufficiently robust to conclude any role of TLR in the anti-inflammatory properties of exercise. PMID- 29461970 TI - Aerobic exercise inhibits acute lung injury: from mouse to human evidence Exercise reduced lung injury markers in mouse and in cells. AB - Acute respiratory distress syndrome (ARDS) is defined as hypoxemic respiratory failure with intense pulmonary inflammation, involving hyperactivation of endothelial cells and neutrophils. Given the anti-inflammatory effects of aerobic exercise (AE), this study investigated whether AE performed daily for 5 weeks would inhibit extra-pulmonary LPS-induced ARDS. C57Bl/6 mice were distributed into Control, Exercise, LPS and Exercise+LPS groups. AE was performed on a treadmill for 5x/week for four weeks before LPS administration. 24hours after the final AE physical test, animals received 100ug of LPS intra-peritoneally. In addition, whole blood cell culture, neutrophils and human endothelial cells were preincubated with IL-10, an anti-inflammatory cytokine induced by exercise. AE reduced total protein levels (p<0.01) and neutrophil accumulation in bronchoalveolar lavage (BAL) (p<0.01) and lung parenchyma (p<0.01). AE reduced BAL inflammatory cytokines IL-1beta, IL-6 and GM-CSF (p<0.001), CXCL1/KC, IL-17, TNF-alpha and IGF-1 (p<0.01). Systemically, AE reduced IL-1beta, IL-6 and IFN gamma (p<0.001), CXCL1/KC (p<0.01) and TNF-alpha (p<0.05). AE increased IL-10 levels in serum (p<0.001) and BAL (p<0.001). Furthermore, AE increased superoxide dismutase SOD (p<0.01) and decreased superoxide anion accumulation in the lungs (p<0.01). Lastly, pre-incubation with IL-10 significantly reduced LPS-induced activation of whole blood cells, neutrophils and HUVECs, as observed by reduced production of IL-1beta, IL-6, IL-8 and TNF-alpha. Our data suggest that AE inhibited LPS-induced lung inflammation by attenuating inflammatory cytokines and oxidative stress markers in mice and human cell culture via enhanced IL-10 production. PMID- 29461971 TI - Microparticles and Exercise in Clinical Populations. AB - Microparticles (MPs) are shed membrane vesicles released from a variety of cell types in response to cellular activation or apoptosis. They are elevated in a wide variety of disease states and have been previously measured to assess both disease activity and severity. However, recent research suggests that they also possess bioeffector functions, including but not limited to promoting coagulation and thrombosis, inducing endothelial dysfunction, increasing pro-inflammatory cytokine release and driving angiogenesis, thereby increasing cardiovascular risk. Current evidence suggests that exercise may reduce both the number and pathophysiological potential of circulating MPs, making them an attractive therapeutic target. However, the existing body of literature is largely comprised of in vitro or animal studies and thus drawing meaningful conclusions with regards to health and disease remains difficult. In this review, we highlight the role of microparticles in disease, comment on the use of exercise and dietary manipulation as a therapeutic strategy, and suggest future research directions that would serve to address some of the limitations present in the research to date.

PMID- 29461974 TI - Comparison of k Q factors measured with a water calorimeter in flattening filter free (FFF) and conventional flattening filter (cFF) photon beams. AB - Recently flattening filter free (FFF) beams became available for application in modern radiotherapy. There are several advantages of FFF beams over conventional flattening filtered (cFF) beams, however differences in beam spectra at the point of interest in a phantom potentially affect the ion chamber response. Beams are also non-uniform over the length of a typical reference ion chamber and recombination is usually larger. Despite several studies describing FFF beam characteristics, only a limited number of studies investigated their effect on k Q factors. Some of those studies predicted significant discrepancies in k Q factors (0.4% up to 1.0%) if TPR20,10 based codes of practice (CoPs) were to be used. This study addresses the question to which extent k Q factors, based on a TPR20,10 CoP, can be applied in clinical reference dosimetry. It is the first study that compares k Q factors measured directly with an absorbed dose to water primary standard in FFF-cFF pairs of clinical photon beams. This was done with a transportable water calorimeter described elsewhere. The measurements corrected for recombination and beam radial non-uniformity were performed in FFF-cFF beam pairs at 6 MV and 10 MV of an Elekta Versa HD for a selection of three different Farmer-type ion chambers (eight serial numbers). The ratio of measured k Q factors of the FFF-cFF beam pairs were compared with the TPR20,10 CoPs of the NCS and IAEA and the %dd(10) x CoP of the AAPM. For the TPR20,10 based CoPs differences less than 0.23% were found in k Q factors between the corresponding FFF-cFF beams with standard uncertainties smaller than 0.35%, while for the %dd(10) x these differences were smaller than 0.46% and within the expanded uncertainty of the measurements. Based on the measurements made with the equipment described in this study the authors conclude that the k Q factors provided by the NCS-18 and IAEA TRS-398 codes of practice can be applied for flattening filter free beams without additional correction. However, existing codes of practice cannot be applied ignoring the significant volume averaging effect of the FFF beams over the ion chamber cavity. For this a corresponding volume averaging correction must be applied. PMID- 29461975 TI - Effect on growth and osteoblast mineralization of hydroxyapatite-zirconia (HA ZrO2) obtained by a new low temperature system. AB - Ceramics and bioceramics, such as hydroxyapatite and zirconium, are used in bone tissue engineering. Hydroxyapatite has chemical properties similar to bone while zirconium offers suitable mechanical properties. The aim of this article is to evaluate the ability to support cell growth and osteoblastic mineralization of hydroxyapatite-zirconium obtained by a new system based on different low temperatures, such as 873 K (HZ600), 923 K (HZ650) and 973 K (HZ700). Hydroxyapatite-zirconia obtained by this new system was examined in terms of thermogravimetric features and x-ray diffractograms. Furthermore, the ability for supporting osteoblast growth and mineralization were analyzed. By x-ray diffraction analysis, we clearly demonstrated that no high-temperature processing was required. Moreover, it is possible to form tetragonal-zirconium at 923 K. Proliferation assays showed that osteoblast growth was not influenced by any of the composite evaluated. Regarding the osteogenic marker Col1, a 2-fold increase in expression was observed for HZ650 compared to HZ600 and HZ700. Interestingly, osteoblasts grown on HZ650 showed globular accretions covered with collagen bundles and calcium-rich extracellular matrix whereas HZ600 and HZ700 showed no phosphate or calcium deposits. This study demonstrated that at 923 K it is possible to generate stable tetragonal-zirconium and the resulting HZ650 composite is able to promote a suitable osteoblast mineralization process.

In vitro mycobacterial outgrowth assays are thought to better capture the complexity of the human host/Mycobacterium tuberculosis (Mtb) interaction. Here, we used a mycobacterial growth inhibition assay (MGIA) based on peripheral blood mononuclear cells to investigate the capacity to control outgrowth of bacille Calmette-Guerin (BCG). Interestingly, strong control of BCG outgrowth was observed almost exclusively in individuals with recent exposure to Mtb, but not in (long-term) latent TB infection, and only modestly in BCG vaccinees. Mechanistically, control of mycobacterial outgrowth strongly correlated with the presence of a CD14dim monocyte population, but also required the presence of T cells. The nonclassical monocytes produced CXCL10, and CXCR3 receptor blockade inhibited the capacity to control BCG outgrowth. Expression of CXCR3 splice variants was altered in recently Mtb-exposed individuals. Cytokines previously associated with trained immunity were detected in MGIA supernatants, and CXCL9, CXCL10, and CXCL11 represent new markers of trained immunity. These data indicate that CXCR3 ligands are associated with trained immunity and are critical factors in controlling mycobacterial outgrowth. In conclusion, control of mycobacterial outgrowth early after exposure to Mtb is the result of trained immunity mediated by a CXCL10-producing nonclassical CD14dim monocyte subset.

AB - BACKGROUND: Sporadic vascular malformations (VMs) are complex congenital anomalies of blood vessels that lead to stroke, life-threatening bleeds, disfigurement, overgrowth, and/or pain. Therapeutic options are severely limited, and multidisciplinary management remains challenging, particularly for high-flow arteriovenous malformations (AVM). METHODS: To investigate the pathogenesis of sporadic intracranial and extracranial VMs in 160 children in which known genetic causes had been excluded, we sequenced DNA from affected tissue and optimized analysis for detection of low mutant allele frequency. RESULTS: We discovered multiple mosaic-activating variants in 4 genes of the RAS/MAPK pathway, KRAS, NRAS, BRAF, and MAP2K1, a pathway commonly activated in cancer and responsible for the germline RAS-opathies. These variants were more frequent in high-flow than low-flow VMs. In vitro characterization and 2 transgenic zebrafish AVM models that recapitulated the human phenotype validated the pathogenesis of the mutant alleles. Importantly, treatment of AVM-BRAF mutant zebrafish with the BRAF inhibitor vemurafinib restored blood flow in AVM. CONCLUSION: Our findings uncover a major cause of sporadic VMs of different clinical types and thereby offer the potential of personalized medical treatment by repurposing existing licensed cancer therapies. FUNDING: This work was funded or supported by grants from the AVM Butterfly Charity, the Wellcome Trust (UK), the Medical Research Council (UK), the UK National Institute for Health Research, the L'Oreal-Melanoma Research Alliance, the European Research Council, and the National Human Genome Research Institute (US). PMID- 29461978 TI - Surface receptor Toso controls B cell-mediated regulation of T cell immunity. AB - The immune system is tightly controlled by regulatory processes that allow for the elimination of invading pathogens, while limiting immunopathological damage to the host. In the present study, we found that conditional deletion of the cell surface receptor Toso on B cells unexpectedly resulted in impaired proinflammatory T cell responses, which led to impaired immune protection in an acute viral infection model and was associated with reduced immunopathological tissue damage in a chronic inflammatory context. Toso exhibited its B cell inherent immunoregulatory function by negatively controlling the pool of IL-10 competent B1 and B2 B cells, which were characterized by a high degree of self reactivity and were shown to mediate immunosuppressive activity on inflammatory T cell responses in vivo. Our results indicate that Toso is involved in the differentiation/maintenance of regulatory B cells by fine-tuning B cell receptor activation thresholds. Furthermore, we showed that during influenza A-induced pulmonary inflammation, the application of Toso-specific antibodies selectively induced IL-10-competent B cells at the site of inflammation and resulted in decreased proinflammatory cytokine production by lung T cells. These findings suggest that Toso may serve as a novel therapeutic target to dampen pathogenic T cell responses via the modulation of IL-10-competent regulatory B cells. PMID- 29461982 TI - Immune-mediated Pericarditis With Pericardial Tamponade During Nivolumab Therapy. AB - A 69-year-old man with metastatic lung adenocarcinoma presented with pericarditis and pericardial tamponade during nivolumab treatment, despite near-complete response on images performed during response evaluation. Further investigation found no evidence of pericardial or pleural cancer involvement, and pathologic evaluation showed immune-related adverse effect. Surgical and steroid treatments were used, with excellent results, and no disease progression on follow-up despite drug discontinuation because of toxicity. Although life-threatening immune-related adverse effects are not frequent when using checkpoint inhibitors, and cardiotoxicity is very rare, different clinical manifestations may occur, and some of them can be fatal in case of inadequate management. It may be challenging to make an etiological diagnosis; however, favorable outcomes can be achieved when prompt directed treatment is promoted. PMID- 29461981 TI - CYP3A4 mutation causes vitamin D-dependent rickets type 3. AB - Genetic forms of vitamin D-dependent rickets (VDDRs) are due to mutations impairing activation of vitamin D or decreasing vitamin D receptor responsiveness. Here we describe two unrelated patients with early-onset rickets, reduced serum levels of the vitamin D metabolites 25-hydroxyvitamin D and 1,25 dihydroxyvitamin D, and deficient responsiveness to parent and activated forms of vitamin D. Neither patient had a mutation in any genes known to cause VDDR; however, using whole exome sequencing analysis, we identified a recurrent de novo missense mutation, c.902T>C (p.I301T), in CYP3A4 in both subjects that alters the conformation of substrate recognition site 4 (SRS-4). In vitro, the mutant CYP3A4 oxidized 1,25-dihydroxyvitamin D with 10-fold greater activity than WT CYP3A4 and 2-fold greater activity than CYP24A1, the principal inactivator of vitamin D metabolites. As CYP3A4 mutations have not previously been linked to rickets, these findings provide insight into vitamin D metabolism and demonstrate that accelerated inactivation of vitamin D metabolites represents a mechanism for vitamin D deficiency. PMID- 29461979 TI - Tandem bispecific neutralizing antibody eliminates HIV-1 infection in humanized mice. AB - The discovery of an HIV-1 cure remains a medical challenge because the virus rebounds quickly after the cessation of combination antiretroviral therapy (cART). Here, we investigate the potential of an engineered tandem bispecific broadly neutralizing antibody (bs-bnAb) as an innovative product for HIV-1 prophylactic and therapeutic interventions. We discovered that by preserving 2 single-chain variable fragment (scFv) binding domains of each parental bnAb, a single gene-encoded tandem bs-bnAb, BiIA-SG, displayed substantially improved breadth and potency. BiIA-SG neutralized all 124 HIV-1-pseudotyped viruses tested, including global subtypes/recombinant forms, transmitted/founder viruses, variants not susceptible to parental bnAbs and to many other bnAbs with an average IC50 value of 0.073 MUg/ml (range < 0.001-1.03 MUg/ml). In humanized mice, an injection of BiIA-SG conferred sterile protection when administered prior to challenges with diverse live HIV-1 stains. Moreover, whereas BiIA-SG delayed viral rebound in a short-term therapeutic setting when combined with cART, a single injection of adeno-associated virus-transferred (AAV-transferred) BiIA-SG gene resulted dose-dependently in prolonged in vivo expression of BiIA SG, which was associated with complete viremia control and subsequent elimination of infected cells in humanized mice. These results warrant the clinical development of BiIA-SG as a promising bs-bnAb-based biomedical intervention for the prevention and treatment of HIV-1 infection. PMID- 29461983 TI - Corticosterone impairs flexible adjustment of spatial navigation in an associative place-reward learning task. AB - Cognitive challenges are often accompanied by a discharge of stress hormones, which in turn modulate multiple brain areas. Among these, the medial temporal lobe and the prefrontal cortex are critically involved in high-order cognitive functions such as learning, memory, and decision-making. Previous studies assessing the effects of corticosterone on spatial memory found an increase or a decrease in performance depending on the timing of stress hormone discharge relative to the behavioral task. Most of these studies, however, made use of aversively motivated behaviors, whereas less is known about corticosteroid effects on flexible learning during reward-driven spatial navigation. To study how corticosterone modulates flexible spatial learning, we tested rats on a place reward association task where hormone treatment was administered immediately after a session presenting a change in reward locations. The corticosterone treated group showed delayed learning during the initial sessions and suboptimal memory consolidation throughout testing. Repeated training on the novel reward positions improved performance and eliminated differences from the control group. We conclude that a marked increase in plasma corticosterone levels immediately after training impairs the flexible formation of new place-reward associations.

AB - HLA-B*57 control of HIV involves enhanced CD8+ T cell responses against infected cells, but extensive heterogeneity exists in the level of HIV control among B*57+ individuals. Using whole-genome sequencing of untreated B*57+ HIV-1-infected controllers and noncontrollers, we identified a single variant (rs643347A/G) encoding an isoleucine-to-valine substitution at position 47 (I47V) of the inhibitory killer cell immunoglobulin-like receptor KIR3DL1 as the only significant modifier of B*57 protection. The association was replicated in an independent cohort and across multiple outcomes. The modifying effect of I47V was confined to B*57:01 and was not observed for the closely related B*57:03. Positions 2, 47, and 54 tracked one another nearly perfectly, and 2 KIR3DL1 allotypes differing only at these 3 positions showed significant differences in binding B*57:01 tetramers, whereas the protective allotype showed lower binding. Thus, variation in an immune NK cell receptor that binds B*57:01 modifies its protection. These data highlight the exquisite specificity of KIR-HLA interactions in human health and disease. PMID- 29461985 TI - Adult and Adolescent Patient Evaluations of Electroconvulsive Therapy in Comparison to Other Therapeutic Modalities. AB - OBJECTIVES: There is an increasing awareness of the importance of patients' subjective evaluations of therapy. Regarding electroconvulsive therapy (ECT), the results are conflicting. We hypothesized that making a comparison between patients' satisfaction with ECT and other forms of psychiatric therapies would capture personal experience as opposed to opinion about the treatment modalities. We compared adult responses to adolescent responses. METHODS: Four unmatched patient groups were recruited (N = 98) and were divided as follows: (a) patients treated with ECT as adolescents (n = 13), (b) patients treated with ECT as adults (n = 25), (c) patients hospitalized as adolescents but not treated with ECT (n = 30), and (d) patients hospitalized as adults but not treated with ECT (n = 30). All patients were interviewed using similar questions related to their satisfaction regarding the treatment modalities they experienced, including psychotherapy, pharmacotherapy, hospitalization and ECT, and years after being treated. RESULTS: Adults and adolescents viewed ECT as a legitimate and effective form of treatment (70%). Patients who were treated with ECT had a more positive attitude toward this treatment compared with patients who had not been treated with ECT. In comparison to other treatment modalities, ECT was considered by both adolescents and adults as the least effective form of therapy. Psychotherapy was considered the most effective, specifically among adolescents. CONCLUSIONS: Comparing patients' satisfaction in regard to different therapeutic modalities can potentially help clarify discrepancies in patient reports on satisfaction with ECT. Patients' satisfaction with ECT, just like their clinical response to ECT, is more dichotomous than with other forms of therapy.

PMID- 29461989 TI - Participants' Experiences of a Sexual Counseling Intervention During Cardiac Rehabilitation: A Nested Qualitative Study Within the CHARMS Pilot Randomized Controlled Trial. AB - BACKGROUND: International guidelines recommend sexual assessment and counseling be offered to all patients with cardiovascular disease during cardiac rehabilitation. However, sexual problems are infrequently addressed. The Cardiac Health and Relationship Management and Sexuality (CHARMS) intervention is a complex, multilevel intervention designed to increase the provision of sexual counseling in cardiac rehabilitation. It was piloted in 2 cardiac rehabilitation centers to assess the acceptability and feasibility of the intervention and to inform and refine a definitive cluster randomized controlled trial protocol. OBJECTIVES: The aim of this study was to explore the experiences, perceptions, and opinions of patients, partners, and cardiac rehabilitation staff who participated in the CHARMS staff-led patient education class. METHODS: A qualitative, descriptive study using semistructured interviews to collect the data. Cardiac rehabilitation staff (n = 8) were interviewed when the intervention commenced in their center and 3 months later (n = 6). Patients (n = 19) and partners (n = 2) were interviewed after delivery of the class; 7 were interviewed again 3 months postintervention to explore temporal changes in opinions. RESULTS: Most cardiac rehabilitation staff were comfortable delivering the CHARMS intervention but would prefer a less structured format. Some staff perceived discomfort among patients. Few patients reported discomfort. Most patients and partners considered that the intervention was a welcome and acceptable part of a cardiac rehabilitation program. CONCLUSION: Incorporating sexual counseling into cardiac rehabilitation programs is feasible. Although the views of the patients and staff diverged on a number of issues including the perceived comfort of patients, its inclusion was welcomed by patients and was acceptable overall to both staff and patients. PMID- 29461991 TI - Technology's Role in Quality Improvement and Operational Efficiency. AB - Technology for technology's sake is never a good idea. There must be a purpose behind it. It must help us do our jobs better. Technology allows healthcare to remain affordable and, as such, accessible. Technology must increase access to care, improve safety, make test results more reliable, and help teams communicate better for a seamless care experience.Avera Health, a health system based in Sioux Falls, South Dakota, comprises 330 facilities in 100 communities in five states. Sponsored by the Benedictine and Presentation Sisters, Avera is a healthcare ministry whose employees deliver high-quality care with compassion. We have been early innovators in using technology to deliver a high standard of service.Avera has been nationally recognized for its innovation. For 18 of the past 19 years, the system has been named to Hospitals & Health Networks magazine's list of Health Care's Most Wired and has been designated as "advanced" for reasons that include the development of the most extensive telehealth network serving rural healthcare facilities. Avera also won the Most Wired Innovator Award in 2011 and 2012. Avera's flagship 545-bed tertiary facility, Avera McKennan Hospital & University Health Center, has received Stage 7 recognition from HIMSS Analytics.Avera leaders have developed a spirit of inquiry and a culture of innovation. We have fostered change by aligning our care into service lines that help ensure that wherever people walk in our doors, they will receive the same quality care. In several cases, we have innovated through strategic partnerships. In this article, we describe how technology helps sustain our culture of innovation. PMID- 29461992 TI - Healthcare's Future: Strategic Investment in Technology. AB - Recent and rapid advances in the implementation of technology have greatly affected the quality and efficiency of healthcare delivery in the United States. Simultaneously, diverse generational pressures-including the consumerism of millennials and unsustainable growth in the costs of care for baby boomers-have accelerated a revolution in healthcare delivery that was marked in 2010 by the passage of the Affordable Care Act.Against this backdrop, Maryland and the Centers for Medicare & Medicaid Services entered into a partnership in 2014 to modernize the Maryland All-Payer Model. Under this architecture, each Maryland hospital negotiates a global budget revenue agreement with the state's rate setting agency, limiting the hospital's annual revenue to the budgetary cap established by the state.At Atlantic General Hospital (AGH), leaders had established a disciplined strategic planning process in which the board of trustees, medical staff, and administration annually agree on goals and initiatives to achieve the objectives set forth in its five-year strategic plans. This article describes two initiatives to improve care using technology. In 2006, AGH introduced a service guarantee in the emergency room (ER); the ER 30-Minute Promise assures patients that they will be placed in a bed or receive care within 30 minutes of arrival in the ER. In 2007, several independent hospitals in the state formed Maryland eCare to jointly contract for intensive care unit (ICU) physician coverage via telemedicine. This technology allows clinical staff to continuously monitor ICU patients remotely. The positive results of the ER 30 Minute Promise and Maryland eCare program show that technological advances in an independent, small, rural hospital can make a significant impact on its ability to maintain independence. AGH's strategic investments prepared the organization well for the transition in 2014 to a value-based payment system.

AB - OBJECTIVE: To document variability among caregivers' priorities when considering medication to treat their Children's attention-deficit hyperactivity disorder (ADHD) and explore associations between these priorities and medication-related improvements. METHODS: Caregivers of children, ages 4 to 14 years, diagnosed with ADHD were recruited from outpatient clinics and support groups across Maryland. A survey gathered data on caregiver-reported concerns when considering ADHD medication, demographic characteristics, and observed and desired improvements in their child's ADHD. A validated Best-Worst Scaling instrument assessed priorities among 16 concerns when considering ADHD medication. Latent class analysis identified subgroups with similar ADHD medication concerns. Differences in self reported medication-related improvements were examined across subgroups. RESULTS: The 184 participants (mean = 42 yrs) were primarily the biological mother, 68% white and 25% black. Their children were mostly male (73%) and using medication (81%). Overall, the most important ADHD medication concerns were the child becoming a successful adult (p < 0.0001), school behavior improvements (p < 0.0001), and better grades (p < 0.0001). Others thinking badly of the child was a significantly less important concern (p < 0.0001). Three subgroups were identified: short-term outcomes-oriented group (39%), long-term outcomes-oriented group (37%), and side effects/safety-oriented group (27%). Relative to the other 2 groups, a smaller proportion of the side effects/safety-oriented group desired these improvements (p < 0.2618). CONCLUSION: Most caregivers prioritize short- and long-term outcomes when considering ADHD medication. However, those most concerned with long- or short-term outcomes tended to desire additional improvements in their child's ADHD. PMID- 29461997 TI - Best-Worst Scaling to Prioritize Outcomes Meaningful to Caregivers of Youth with Mental Health Multimorbidities: A Pilot Study. AB - OBJECTIVE: Health care decision-making for youth with mental health multimorbidity is guided by outcomes that are considered most meaningful and important. The study objective was to pilot test a best-worst scaling (BWS) instrument designed to assess trade-offs among caregiver-defined, meaningful health care outcomes. METHODS: A BWS was designed with continuous stakeholder involvement to elicit caregiver-defined outcomes in 4 domains: school, behavioral, social, and independence. Four attributes were identified for each outcome domain, for a total of 16 attributes. Using a balanced incomplete block design, a BWS instrument was developed with 16 choice task questions displaying 6 attributes at a time. A convenience sample was selected from Maryland caregivers of children who were 21 years old or younger and had a developmental delay and a comorbid mental health condition. Participants completed a survey that included demographics and the BWS instrument. Conditional logit was used to estimate utility scores and 95% confidence intervals (CI) for each attribute, which were ranked in order of importance. Attribute statements were refined after a respondent debriefing session. RESULTS: A total of 38 caregivers participated in the pilot study. Child safety to self was the most important outcome (1.01, CI, 0.78-1.24). This was followed by securing support for an Individualized educational plan in school (0.77, CI, 0.54-1.01) and the child being able to stay in school all day (0.53, CI, 0.29-0.77). CONCLUSION: BWS scenarios that resemble real-life decision-making can be a useful tool to identify preferences for health care outcomes.

AB - PURPOSE: The aim of this case report was to demonstrate the repair of a large sinus membrane perforation related to a sinus floor augmentation procedure, using leukocyte platelet-rich fibrin (L-PRF), for subsequent rehabilitation of a partially edentulous patient. MATERIALS AND METHODS: The patient presented the absence of teeth numbers 18, 17, and 16, associated with insufficient bone height because of the maxillary sinus pneumatization. A maxillary inlay bone graft was proposed, however, during the sinus floor augmentation procedure, a large portion of the sinus membrane was ruptured. To avoid interruption of the surgical procedure, membrane mending was proposed using L-PRF and collagen membranes. RESULTS: After 8 months, 2 external hexagon connection dental implants were placed in the 16 and 17 teeth regions, and a screw-retained implant-supported prosthesis was installed. CONCLUSION: The use of L-PRF associated with collagen membrane was efficient for the sealing of the sinus membrane perforation and enabled bone formation for subsequent implant installation. PMID- 29462000 TI - Clinical Burdens of beta-Thalassemia Major in Affected Children. AB - BACKGROUND: beta-thalassemia major (BTM) is an inherited blood disorder leading to severe anemia. A better understanding of BTM complications can be considered an important factor in developing effective health care provision. METHOD: A descriptive exploratory design was used to identify the clinical burden of BTM from affected children's perspective. A convenience sample of 45 patients with BTM, accompanied by a family member, was recruited from a governmental hospital during April-May 2015. RESULTS: The most reported clinical burden was facial deformity 86.9%, followed by systematic infection (48.8%), growth delay (44.4%), and liver problems (39.9%). Patient age was significantly associated with clinical burdens such as bone pain and facial deformity. The number of blood transfusions received was associated with growth delay and bone pain. CONCLUSION: This study highlights the clinical burdens of thalassemia on affected children, in terms of physical appearance, growth delay and other burdens.

PMID- 29462003 TI - Toll Like Receptor 4 Signaling Licenses the Cytosolic Transport of Lipopolysaccharide from Bacterial Outer Membrane Vesicles. AB - Outer membrane vesicles (OMVs), released by variety of bacteria, are membrane enclosed entities enriched in microbial components, toxins and virulent factors. OMVs could deliver lipopolysaccharide (LPS) into the cytosol of host cells and subsequently activate caspase-11, which critically orchestrates immune responses and mediates septic shock. Though it is known that caspase-11 is activated by intracellular LPS, how OMVs deliver LPS into the cytosol remains largely unknown. Here we show that the activation of toll like receptor 4 (TLR4), a LPS receptor on the cytoplasmic membrane, licenses macrophages to transport LPS from OMVs into the cytosol through TIR domain-containing adaptor-inducing interferon-beta (TRIF). TRIF-mediated cytosolic delivery of LPS from OMVs depends on the production of type 1 interferon and the expression of guanylate-binding proteins (GBPs). Deletion of TRIF or GBPs prevents pyroptosis and lethality induced by OMVs or OMVs-releasing E.coli. Together, these findings provide novel insight into how host coordinates extracellular and intracellular LPS sensing to orchestrate immune responses during gram-negative bacterial infection. PMID- 29462004 TI - How Surrogate Decision-Makers for Patients With Chronic Critical Illness Perceive and Carry Out Their Role. AB - OBJECTIVES: Family members commonly make medical decision for patients with chronic critical illness. This study examines how family members approach this decision-making role in real time. DESIGN: Qualitative analysis of interviews with family members in the intervention arm of a randomized controlled communication trial. SETTINGS: Medical ICUs at four U.S. hospitals. PARTICIPANTS: Family members of patients with chronic critical illness (adults mechanically ventilated for >= 7 d and expected to remain ventilated and survive for >= 72 hr) who participated in the active arm of a communication intervention study. INTERVENTIONS: Family members participated in at least two content-guided, informational, and emotional support meetings led by a palliative care physician and nurse practitioner. MEASUREMENTS AND MAIN RESULTS: Grounded theory was used for qualitative analysis of 66 audio recordings of meetings with 51 family members. Family members perceived their role in four main ways: voice of the patient, advocate for the patient, advocate for others, and advocate for oneself. Their decision-making was characterized by balancing goals, sharing their role, keeping perspective, remembering previous experiences, finding sources of strength, and coping with various burdens. CONCLUSIONS: Family members take a multifaceted approach as they participate in decision-making. Understanding how surrogates perceive and act in their roles may facilitate shared decision-making among clinicians and families during critical care. PMID- 29462005 TI - Oncological Benefits of Neoadjuvant Chemoradiation With Gemcitabine Versus Upfront Surgery in Patients With Borderline Resectable Pancreatic Cancer: A Prospective, Randomized, Open-label, Multicenter Phase 2/3 Trial. AB - OBJECTIVE: This study was performed to determine whether neoadjuvant treatment increases survival in patients with BRPC. SUMMARY BACKGROUND DATA: Despite many promising retrospective data on the effect of neoadjuvant treatment for borderline resectable pancreatic cancer (BRPC), no high-level evidence exists to support the role of such treatment. METHODS: This phase 2/3 multicenter randomized controlled trial was designed to enroll 110 patients with BRPC who were randomly assigned to gemcitabine-based neoadjuvant chemoradiation treatment (54 Gray external beam radiation) followed by surgery or upfront surgery followed by chemoradiation treatment from four large-volume centers in Korea. The primary endpoint was the 2-year survival rate (2-YSR). Interim analysis was planned at the time of 50% case enrollment. RESULTS: After excluding the patients who withdrew consent (n = 8) from the 58 enrolled patients, 27 patients were allocated to neoadjuvant treatment and 23 to upfront surgery groups. The overall 2-YSR was 34.0% with a median survival of 16 months. In the intention-to-treat analysis, the 2-YSR and median survival were significantly better in the neoadjuvant chemoradiation than the upfront surgery group [40.7%, 21 months vs 26.1%, 12 months, hazard ratio 1.495 (95% confidence interval 0.66-3.36), P = 0.028]. R0 resection rate was also significantly higher in the neoadjuvant chemoradiation group than upfront surgery (n = 14, 51.8% vs n = 6, 26.1%, P = 0.004). The safety monitoring committee decided on early termination of the study on the basis of the statistical significance of neoadjuvant treatment efficacy. CONCLUSION: This is the first prospective randomized controlled trial on the oncological benefits of neoadjuvant treatment in BRPC. Compared to upfront surgery, neoadjuvant chemoradiation provides oncological benefits in patients with BRPC. PMID- 29462006 TI - A Combination of Robotic Approach and ERAS Pathway Optimizes Outcomes and Cost for Pancreatoduodenectomy. AB - OBJECTIVE: To determine the impact of enhanced recovery after surgery (ERAS) pathway implementation on outcomes, and cost of robotic and open pancreatoduodenectomy. BACKGROUND: ERAS pathways have shown benefit in open pancreatoduodenectomy (OPD). The impact of ERAS on robotic pancreatoduodenectomy (RPD) is unknown. METHODS: Retrospective review of consecutive RPD and OPDs in the pre-ERAS (July, 2014-July, 2015) and ERAS (July, 2015-July, 2016) period. Univariate and multivariate logistic regression was used to determine impact of ERAS and operative approach alone, or in combination (pre-ERAS + OPD, pre-ERAS + RPD, ERAS + OPD, ERAS + RPD) on length of hospital stay (LOS) and overall cost. RESULTS: In all, 254 consecutive pancreatoduodenectomies (RPD 62%, OPD 38%) were analyzed (median age 67, 47% female). ERAS patients had shorter LOS (6 vs 8 days; P = 0.004) and decreased overall cost (USD 20,362 vs 24,277; P = 0.001) compared with non-ERAS patients, whereas RPD was associated with decreased LOS (7 vs 8 days; P = 0.0001) and similar cost compared with OPD. On multivariable analysis (MVA), RPD was predictive of shorter LOS [odds ratio (OR) 0.33, confidence interval (CI) 0.16-0.67, P = 0.002), whereas ERAS was protective against high cost (OR 0.57, CI 0.33-0.97, P = 0.037). On MVA, when combining operative approach with ERAS pathway use, a combined ERAS + RPD approach was associated with reduced LOS and optimal cost compared with other combinations (pre-ERAS + OPD, pre-ERAS + RPD, ERAS + OPD). CONCLUSION: ERAS implementation is independently associated with cost savings for pancreatoduodenectomy. A combination of ERAS and robotic approach synergistically decreases hospital stay and overall cost compared with other strategies. PMID- 29462007 TI - Risk Factors for Recurrence After Treatment of N1b Papillary Thyroid Carcinoma. AB - OBJECTIVES: To examine risk factors for posttreatment recurrence in papillary thyroid carcinoma (PTC) patients with initial presentation of lateral neck metastasis (N1b). SUMMARY OF BACKGROUND DATA: N1b PTC recurs after definitive treatment. METHODS: Study subjects were 437 consecutive PTC patients who underwent total thyroidectomy and therapeutic neck dissection of central and lateral compartments and postoperative radioactive iodine ablation therapy. The patients' demographics and pathological factors, including factors related to tumors and lymph nodes (LNs), and postoperative thyroglobulin levels were reviewed. Univariate and multivariate Cox proportional hazards regression analyses were used to identify factors associated with recurrence-free survival (RFS). RESULTS: During a median follow-up of 83 months (range, 32-135 months), recurrence occurred in 81 (18.1%) patients. Univariate analyses showed that male sex, tumor size, macroscopic extrathyroidal extension, perineural invasion, extranodal extension, LN involvement, LN ratio, MACIS score, and postoperative serum levels of thyroglobulin were significantly associated with RFS (P < 0.05). Multivariate analyses revealed that LN ratio (> 0.25) in the lateral compartment (adjusted hazard ratio = 2.099, 95% confidence interval = 1.278-3.448; P = 0.003), and postoperative serum levels of stimulated (>5.0 ng/mL; 3.172, 1.661 6.056, P < 0.001) and unstimulated (>0.1 ng/mL; 3.200, 1.569-6.526, P = 0.001) thyroglobulin were independent predictors of any-site RFS. Clinical and tumor factors were not independent predictors of RFS outcomes (P > 0.1). CONCLUSIONS: Posttreatment recurrence is predicted by the LN ratio in the lateral compartment and postoperative serum levels of thyroglobulin in patients with metastatic PTC in the lateral neck. PMID- 29462008 TI - Opioid Overdose-the Surgeon's Role. AB - : With increased focus on the potential harms of surgical opioid prescribing, surgeons should be cognizant of the risk of opioid-related adverse events in their patients, including overdose. Risk factors for overdose may be more prevalent than surgeons think, and include high current opioid use, previous or existing substance use disorder, history of overdose, or certain medical comorbidities. The first step to protecting surgical patients from opioid overdose is adequate screening for risk factors; appropriate patient counseling and prudent prescribing practices can then help protect at-risk patients. PMID- 29462009 TI - Gender Differences in Utilization of Duty-hour Regulations, Aspects of Burnout, and Psychological Well-being Among General Surgery Residents in the United States. AB - OBJECTIVE: The aim of the study was to (1) assess differences in how male and female general surgery residents utilize duty-hour regulations and experience aspects of burnout and psychological well-being, and (2) to explore reasons why these differing experiences exist. BACKGROUND: There may be differences in how women and men enter, experience, and leave residency programs. METHODS: A total of 7395 residents completed a survey (response rate = 99%). Logistic regression models were developed to examine the association between gender and resident outcomes. Semistructured interviews were conducted with 42 faculty and 56 residents. Transcripts were analyzed thematically using a constant comparative approach. RESULTS: Female residents reported more frequently staying in the hospital >28 hours or working >80 hours in a week (>=3 times in a month, P < 0.001) and more frequently feeling fatigued and burned out from their work (P < 0.001), but less frequently "treating patients as impersonal objects" or "not caring what happens" to them (P < 0.001). Women reported more often having experienced many aspects of poor psychological well-being such as feeling unhappy and depressed or thinking of themselves as worthless (P < 0.01). In adjusted analyses, associations remained significant. Themes identified in the qualitative analysis as possible contributory factors to gender differences include a lack of female mentorship/leadership, dual-role responsibilities, gender blindness, and differing pressures and approaches to patient care. CONCLUSIONS: Female residents report working more, experiencing certain aspects of burnout more frequently, and having poorer psychological well-being. Qualitative themes provide insights into possible cultural and programmatic shifts to address the concerns for female residents. PMID- 29462010 TI - ERAS Implementation-Time To Move Forward. PMID- 29462011 TI - Positive End-expiratory Pressure Alone Minimizes Atelectasis Formation in Nonabdominal Surgery: A Randomized Controlled Trial. AB - BACKGROUND: Various methods for protective ventilation are increasingly being recommended for patients undergoing general anesthesia. However, the importance of each individual component is still unclear. In particular, the perioperative use of positive end-expiratory pressure (PEEP) remains controversial. The authors tested the hypothesis that PEEP alone would be sufficient to limit atelectasis formation during nonabdominal surgery. METHODS: This was a randomized controlled evaluator-blinded study. Twenty-four healthy patients undergoing general anesthesia were randomized to receive either mechanical ventilation with PEEP 7 or 9 cm H2O depending on body mass index (n = 12) or zero PEEP (n = 12). No recruitment maneuvers were used. The primary outcome was atelectasis area as studied by computed tomography in a transverse scan near the diaphragm, at the end of surgery, before emergence. Oxygenation was evaluated by measuring blood gases and calculating the ratio of arterial oxygen partial pressure to inspired oxygen fraction (PaO2/FIO2 ratio). RESULTS: At the end of surgery, the median (range) atelectasis area, expressed as percentage of the total lung area, was 1.8 (0.3 to 9.9) in the PEEP group and 4.6 (1.0 to 10.2) in the zero PEEP group. The difference in medians was 2.8% (95% CI, 1.7 to 5.7%; P = 0.002). Oxygenation and carbon dioxide elimination were maintained in the PEEP group, but both deteriorated in the zero PEEP group. CONCLUSIONS: During nonabdominal surgery, adequate PEEP is sufficient to minimize atelectasis in healthy lungs and thereby maintain oxygenation. Thus, routine recruitment maneuvers seem unnecessary, and the authors suggest that they should only be utilized when clearly indicated. VISUAL ABSTRACT: An online visual overview is available for this article at http://links.lww.com/ALN/B728. PMID- 29462013 TI - Patient Acceptance of Sustained Glaucoma Treatment Strategies. AB - PURPOSE: To assess patient acceptance of different methods for delivering sustained-release, intraocular pressure (IOP)-lowering medications. METHODS: Electronic surveys were administered to 150 patients at 2 glaucoma clinics. Participants were questioned on their willingness to accept: (1) drug-eluting contact lenses, (2) ring inserts (3) punctal plugs, and (4) subconjunctival injections as alternatives to IOP-lowering eye drops based on various success levels. Multivariable logistic regression models determined the association between device type and treatment acceptance adjusting for age, sex, study site, cost burden of drops, and previous contact lens use. RESULTS: The majority (69%) of participants were 55 to 74 years of age, and white (65%), and half were female. The majority of participants would accept contacts (59%), rings (51%), plugs (57%), and subconjunctival injections (52%) if they obviated glaucoma surgery; fewer would accept these devices if they reduced (23% to 35%) or eliminated (27% to 42%) drops. Most participants would also accept contacts (56%), plugs (55%), and subconjunctival injections (53%) if they were more effective than eye drops, whereas only 47% would accept a ring; fewer would accept any device if it were equally or less effective than drops. Participants were also 36% (95% confidence interval=0.44-0.92; P=0.02) less likely to accept rings and 32% (95% confidence interval=0.47-0.98; P=0.04) less likely to accept subconjunctival injections as compared with contacts. CONCLUSION: Most glaucoma patients considered sustained drug-delivery modalities acceptable alternatives to IOP-lowering eye drops, but only when they were said to obviate surgery or demonstrate greater efficacy than eye drops. PMID- 29462014 TI - Surgical Outcome of Replacing a Failed Ahmed Glaucoma Valve by a Baerveldt Glaucoma Implant in the Same Quadrant in Refractory Glaucoma. AB - PURPOSE: The purpose of this study was to describe the surgical technique and outcomes in eyes that underwent surgery to replace a failed Ahmed valve by a Baerveldt glaucoma implant in the same quadrant. METHODS: This study was a retrospective case series of 9 patients. Parameters analyzed include age, glaucoma type, prior surgery, complications, intraocular pressure (IOP), visual acuity, and number of glaucoma medications before and after the surgery. Surgical success was defined as having either an IOP below 21 mm Hg or a 20% IOP reduction, with or without hypotensive agent. RESULTS: The mean follow-up duration was 47 months. After surgery, at the time of final follow-up, the mean IOP decreased from 29.9 mm Hg to 16.7 mm Hg (36% of mean IOP reduction; P=0.008). There was a significant reduction of hypotensive agents from a mean of 4.33 to 2.22 (P=0.02). The visual acuity did not have a significant deterioration (P=0.07). In the final visit, 5 of 9 patients met total success criteria and 2 patients were qualified successes. Two cases failed totally after 69 and 125 months of follow-up. The cumulative probability of total success after 6 months was 76% and this rate remained stable until the sixth year. One patient had bullous keratopathy. Two patients had early postoperative pressure spikes: the first patient was treated by trabeculectomy, and the second by vitrectomy. CONCLUSIONS: A replacement of the failed Ahmed glaucoma valve by a new Baerveldt glaucoma implant in the same quadrant can be a reasonable choice to control refractory glaucoma. PMID- 29462016 TI - Diurnal Variations of Peripapillary and Macular Vessel Density in Glaucomatous Eyes Using Optical Coherence Tomography Angiography. AB - PURPOSE: The purpose of this study was to investigate the diurnal variation in peripapillary and macular vessel density (VD) measurements using optical coherence tomographic angiography (OCT-A) and its correlation to intraocular pressure (IOP) changes in glaucoma patients. METHODS: Prospective, observational cross-sectional study including 37 patients (74 eyes; age, 63.8+/-12.9 y) with open-angle glaucoma. OCT-A imaging and IOP measurements were performed at 08:00, 11:00, 14:00, and 16:00 timepoints on a single day. At each timepoint, 2 scan protocols were used to generate 3-dimensional en face OCT angiograms: 4.5*4.5-mm scan centered on the optic nerve head and 6*6-mm scan centered on the fovea. For each scan mode, the "radial peripapillary capillary" segment, composed of the vasculature of the retinal nerve fiber layer and ganglion cell layer, was calculated. Two trained readers reviewed OCT-A image quality. Only scans with signal strength intensity (SSI) higher than 46 and without image artifacts interfering with measurements were included. Variation in VD measurements assessed using analysis of variance (ANOVA) and the association between VD and IOP changes assessed using linear mixed modeling methods. RESULTS: The optic nerve head and peripapillary VD measurements at 14:00 and 16:00 timepoints were greater than the measurements at 08:00 and 11:00 timepoints. The 14:00 and 16:00 VD measurements were statistically significantly greater (P<0.05) than the 08:00 measurements for the whole en face (50.1% and 50.1% vs. 49.4%), inside disc (50.6% and 50.5% vs. 49.6%), and average peripapillary (58.2% and 58.5% vs. 57.5%) VDs. The macular VD measurements at the 14:00 timepoint were greater than the measurements at 08:00 and 11:00 timepoints. Changes in VD were significantly associated with changes in SSI but not IOP. CONCLUSIONS: Diurnal changes in OCT-A measured VD in glaucoma patients were small and clinically insignificant. These changes were not associated with IOP changes. PMID- 29462015 TI - Macular Vessel Density in Glaucomatous Eyes With Focal Lamina Cribrosa Defects. AB - PURPOSE: To compare optical coherence tomography angiography (OCTA) measured macular vessel density and spectral domain optical coherence tomography (SDOCT) measured macular ganglion cell complex (GCC) thickness in primary open-angle glaucoma eyes with and without focal lamina cribrosa (LC) defects. METHODS: In this cross-sectional, case-control study of patients with primary open-angle glaucoma, 46 eyes of 46 patients with LC defects and 54 eyes of 54 patients without observable LC defects were included. OCTA and SDOCT imaging were performed on the same day by the same operator. Perimetry and swept-source OCT testing used to identify LC defects were conducted within 6 months of OCTA and SDOCT testing. Global and local parafoveal vessel density and macular GCC thickness were compared between study groups. RESULTS: Glaucoma severity was similar between groups (SAP mean deviation=-5.63 and -4.64 dB for eyes with and without LC defects, respectively; P=0.40). Global and local measured parafoveal vessel density was similar between groups (all P>=0.11). GCC focal loss volume was higher in eyes with LC defects than eyes without LC defects (7.2% and 4.97%, respectively; P=0.03). In addition, GCC focal loss volume was topographically related to defect location in LC defect eyes. CONCLUSIONS: Although OCTA macular vessel density was not significantly different between eyes with and without LC defects, focal GCC loss in eyes with LC defects was different. This highlights the importance of not relying solely on vessel density measurements for determining macular changes for diagnosing and detecting glaucomatous progression.

PMID- 29462020 TI - Pubic Hair Restorative Surgery Using Grafts Harvested by the Nonshaven Follicular Unit Extraction Technique. AB - BACKGROUND: Pubic atrichosis or hypotrichosis is quite common among Korean women. Although Korean people are increasingly opening up to Western culture, pubic hair transplantation is still pursued for cultural reasons. However, many hesitate to undergo restorative surgery because follicular unit strip surgery would leave a linear donor scar, preventing patients from hiding their surgical history. Thus, follicle harvesting using nonshaven follicular unit extraction (NS-FUE), aside from many other strengths, is very useful when performing pubic restorative surgery. There has been no previous report concerning the effectiveness of NS-FUE for treating pubic atrichosis or hypotrichosis. OBJECTIVE: To investigate the effectiveness of NS-FUE when performing pubic restorative surgery. MATERIALS AND METHODS: The 50 patients who were included in the study underwent pubic hair restoration using NS-FUE between March 2014 and June 2016 at Dana Plastic Surgery Clinic (Seoul, Korea), and were followed for at least 10 months afterward. Patients and the surgeon completed a survey about donor and recipient site surgical results using a 5-point Likert scale. RESULTS: The average satisfaction scores of patients and surgeon were 4.5 and 4.6, respectively. CONCLUSION: Nonshaven follicular unit extraction is one of the most effective harvesting methods when performing restorative surgery for patients with pubic atrichosis or hypotrichosis. PMID- 29462019 TI - Clinico-Surgical Characteristics of Head and Neck Lipomas. PMID- 29462012 TI - Neuroinflammation and Central Sensitization in Chronic and Widespread Pain. AB - Chronic pain is maintained in part by central sensitization, a phenomenon of synaptic plasticity, and increased neuronal responsiveness in central pain pathways after painful insults. Accumulating evidence suggests that central sensitization is also driven by neuroinflammation in the peripheral and central nervous system. A characteristic feature of neuroinflammation is the activation of glial cells, such as microglia and astrocytes, in the spinal cord and brain, leading to the release of proinflammatory cytokines and chemokines. Recent studies suggest that central cytokines and chemokines are powerful neuromodulators and play a sufficient role in inducing hyperalgesia and allodynia after central nervous system administration. Sustained increase of cytokines and chemokines in the central nervous system also promotes chronic widespread pain that affects multiple body sites. Thus, neuroinflammation drives widespread chronic pain via central sensitization. We also discuss sex-dependent glial/immune signaling in chronic pain and new therapeutic approaches that control neuroinflammation for the resolution of chronic pain. PMID- 29462021 TI - Review of Endovenous Thermal Ablation of the Great Saphenous Vein: Endovenous Laser Therapy Versus Radiofrequency Ablation. AB - BACKGROUND: Endovenous thermal ablation is a popular treatment for varicose veins of the greater saphenous vein. Two common techniques of thermal ablation are endovenous laser therapy (EVLT) and radiofrequency ablation (RFA). OBJECTIVE: The authors compare EVLT and RFA in vein therapy. METHODS: A review was conducted using PubMed. Studies comparing the treatment modalities were gathered and compared on the basis of 5 main standpoints, including: efficacy, side effects, serious complications, recurrence, and quality of life. RESULTS: It was found that EVLT and RFA are both highly efficacious (>80%). Endovenous laser therapy seems to be slightly more efficacious than RFA in numerous studies but its significance is uncertain. Side effect profiles varied regarding postoperative pain and bruising because both were seen to be significantly less using RFA. Serious complications were found to be rare in both with no significant difference in incidence. Recanalization rate was observed to be higher using RFA with uncertainty in significance among various studies. Quality of life improved after both procedures with no significant difference among the 2. CONCLUSION: Efficacy and recurrence rate seem to favor EVLT, whereas postoperative pain and bruising favor RFA. Further studies are needed to validate the significance of the differences found.

PMID- 29462023 TI - Advocating the Development of Next-Generation High-Relaxivity Gadolinium Chelates for Clinical Magnetic Resonance. AB - The question of improved relaxivity, and potential efficacy therein, for a next generation of magnetic resonance gadolinium chelates with extracellular distribution and renal excretion, which could also be viewed from the perspective of dose, is addressed on the basis of historical development, animal experimentation, and human trials. There was no systematic evaluation that preceded the choice of 0.1 mmol/kg as the standard dose for human imaging with the gadolinium chelates. In part, this dose was chosen owing to bloodwork abnormalities seen in phase I and phase II studies. Animal investigations and early clinical trials demonstrated improved lesion detectability at higher doses in the brain, liver, and heart. By designing an agent with substantially improved relaxivity, higher enhancement equivalent to that provided with the conventional gadolinium agents at high dose could be achieved, translating to improved diagnosis and, thus, clinical care. Implicit in the development of such high relaxivity agents would be stability equivalent to or exceeding that of the currently approved macrocyclic agents, given current concern regarding dechelation and gadolinium deposition in the brain, skin, and bone with the linear agents that were initially approved. Development of such next-generation agents with a substantial improvement in relaxivity, in comparison with the current group of approved agents, with a 2-fold increase likely achievable, could lead to improved lesion enhancement, characterization, diagnosis, and, thus, clinical efficacy. PMID- 29462024 TI - Characterization of Small Renal Tumors With Magnetic Resonance Elastography: A Feasibility Study. AB - OBJECTIVES: The aim of this study was to explore the feasibility of magnetic resonance elastography (MRE) for characterizing indeterminate small renal tumors (SRTs) as part of a multiparametric magnetic resonance (MR) imaging protocol. MATERIALS AND METHODS: After institutional review board approval and informed consent were obtained, 21 prospective adults (15 men; median age, 55 years; age range, 25-72 years) with SRT were enrolled. Tumors (2-5 cm O) were imaged using 3 directional, gradient echo MRE. Viscoelastic parametric maps (shear wave velocity [c] and attenuation [alpha]) were analyzed by 2 independent radiologists. Interobserver agreement (Bland-Altman statistics and intraclass correlation coefficients) was assessed. Anatomical T2-weighted, dynamic contrast-enhanced (DCE) and diffusion sequences completed the acquisition protocol. Imaging parameters were compared between groups (Mann-Whitney U test). RESULTS: Quality of MRE was good in 18 cases (mean nonlinearity <50%), including 1 papillary renal cell carcinoma and 1 metanephric adenoma. A cohort of 5 oncocytomas and 11 clear cell renal cell carcinomas (ccRCCs) was analyzed for statistical differences. The MRE viscoelastic parameters were the strongest imaging discriminators: oncocytomas displayed significantly lower shear velocity c (median, 0.77 m/s; interquartile range [IQR], 0.76-0.79) (P = 0.007) and higher shear attenuation alpha (median, 0.087 mm; IQR, 0.082-0.087) (P = 0.008) than ccRCC (medians, 0.92 m/s and 0.066 mm; IQR, 0.84-0.97 and 0.054-0.074, respectively). T2 signal intensity ratio (tumor/renal cortex) was lower in oncocytomas (P = 0.02). The DCE and diffusion MR parameters overlapped substantially (P >= 0.1). Oncocytomas displayed a consistent MRE viscoelastic profile, corresponding to data point clustering in a bidimensional scatter plot. Values for MRE intraclass correlation coefficient were 0.982 for c and 0.984 for alpha, indicating excellent interobserver agreement. CONCLUSIONS: Magnetic resonance elastography is feasible for SRT characterization; MRE viscoelastic parameters were stronger discriminators between oncocytoma and ccRCC than anatomical, DCE and diffusion MR imaging parameters. PMID- 29462025 TI - Primary biliary cholangitis is more severe in previous hepatitis B virus infection patients. AB - OBJECTIVES: The aim of this study was to evaluate the association between previous hepatitis B virus (HBV) infection and the severity of primary biliary cholangitis (PBC). PATIENTS AND METHODS: A total of 379 HBsAg-negative PBC patients were investigated between 2012 and 2017 in this study. Fifty-two of these patients underwent liver biopsy. The enrolled patients were divided into an anti-HBc-positive group and an anti-HBc-negative group; the patients with liver biopsy were further divided into early stage (stage I) and advanced stage (stages II, III, and IV) according to histological assessment. Liver fibrosis was also assessed by noninvasive prognosis scores including the Mayo Risk Score, the Newcastle model, the aspartate aminotransferase-to-platelet ratio index, the fibrosis index based on the four factors (FIB-4), and the albumin-bilirubin score. The difference in disease stage between the two groups was assessed by histological stage and noninvasive scores predicting fibrosis. RESULTS: The histology showed that more patients in the anti-HBc-positive group had advanced stage compared with anti-HBc-negative patients (P<0.05). Higher Mayo Risk Score, the Newcastle model, aminotransferase-to-platelet ratio index, and fibrosis index based on the four factors (all P<0.05) were obtained in all patients except for the albumin-bilirubin score (P=0.096). CONCLUSION: Previous HBV infection was associated with a worse histological stage and advanced fibrosis score of PBC. It appears that the previous HBV infection may have aggravated the PBC severity, potentially leading to poorer outcomes. PMID- 29462026 TI - Anticoagulant therapy for venous thromboembolism in patients with inflammatory bowel disease. AB - BACKGROUND: There is lack of evidence to guide the type, intensity, and the duration of anticoagulation following venous thromboembolism (VTE) in patients with inflammatory bowel disease (IBD). PATIENTS AND METHODS: Registro Informatizado Enfermedad Trombo Embolica (RIETE) is an ongoing, multicenter, observational registry of consecutive patients with symptomatic, objectively confirmed, acute VTE. We used the RIETE database to compare the rate of VTE recurrences and major bleeding during the course of anticoagulation in noncancer patients with or without IBD. RESULTS: As of October 2014, 41 927 patients without active cancer have been recruited in RIETE. Of these, 265 (0.63%) had IBD and 85 (32%) had the VTE during an acute flare. The duration of anticoagulation was similar in patients with VTE during an acute flare (8.3+/-8.8 months), in remission (9.4+/-11.5 months), or without IBD (10.0+/-12.8 months). The rate of VTE recurrences [7.25, 95% confidence interval (CI): 1.46-21.2; 8.84, 95% CI: 3.23-19.2; and 5.85, 95% CI: 5.46-6.26 per 100 patient-years, respectively] and major bleeding (7.25, 95% CI: 1.46-21.2; 2.95, 95% CI: 0.33-10.6; and 4.79, 95% CI: 4.44-5.15, respectively) were similar in all three subgroups. Propensity score matching analysis confirmed the absence of differences in the rate of VTE recurrences (rate ratio: 1.16, 95% CI: 0.54-2.47) or major bleeding (rate ratio: 0.84, 95% CI: 0.31-2.23) between patients with or without IBD. CONCLUSION: Therapeutic anticoagulation for patients with IBD and VTE is as safe and effective as for those with VTE without IBD. PMID- 29462027 TI - Transjugular intrahepatic portosystemic shunt creation for cirrhotic portal hypertension is well tolerated among patients with portal vein thrombosis. AB - BACKGROUND: Portal vein thrombosis (PVT) develops in cirrhotic patients because of stagnation of blood flow. Transjugular intrahepatic portosystemic shunt (TIPS) creates a low-resistance conduit that restores portal venous patency and blood flow. AIM: The effect of PVT on transplant-free survival in cirrhotic patients undergoing TIPS creation was evaluated. PATIENTS AND METHODS: A multicenter, retrospective cohort study of patients who underwent TIPS creation for cirrhotic portal hypertension was carried out. A Cox model with propensity score adjustment was developed to evaluate the effect of PVT on 90-day and 3-year transplant-free survival. A subgroup analysis examining mortality of those with superior and inferior PVT was also carried out. RESULTS: A total of 252 consecutive TIPS creations were assessed, including 65 in patients with PVT. Survival of patients with high Model for End-stage Liver Disease scores (>=18) and PVT was not statistically different compared with patients with low Model for End-stage Liver Disease scores (<18) and no PVT at 90 days (P=0.46) and 3 years (P=0.42). Those with superior PVT had improved 90-day and 3-year survival both compared with patients with a inferior PVT and those without a PVT (P<0.01, all cases). CONCLUSION: The presence of PVT does not impair the prognosis of patients following TIPS creation, particularly in patients with superior portal occlusion. PMID- 29462028 TI - The operative risk and natural history after the diagnosis of ileal penetrating Crohn's disease. AB - BACKGROUND AND PURPOSE: Crohn's disease (CD) is marked by transmural inflammation of the bowel wall leading to stricturing and/or penetrating complications in the majority of patients. The natural history and operative risk after the diagnosis of an ileal penetrating complication is understudied. The aim was to study the disease course and need for surgery in patients diagnosed with a penetrating ileal CD complication and to assess the risk factors associated with worse postoperative outcome. PATIENTS AND METHODS: In this cohort study, all cross sectional imaging exams (computed tomography and/or magnetic resonance imaging) performed between 2006 and 2014 in patients with CD in a tertiary referral centre were reviewed for the presence of ileal penetrating complications (defined as abscesses, phlegmones and/or fistula). Demographic, clinical, biochemical, radiological and endoscopic factors were assessed retrospectively in these patients as well as the need for surgery (intestinal resection and/or strictureplasties) and postoperative complications. RESULTS: In total, 1803 cross sectional imaging exams in 957 CD patients were performed during the study period. In 113 patients, penetrating ileal CD complications were identified. The majority of these patients were referred for surgery (86%) (median time to surgery 1 month, interquartile range: 1-4.9 months). In multivariate analysis, only the presence of abscesses was associated with subsequent surgery (P=0.034; hazard ratio=1.65; 95% confidence interval: 1.04-2.61). Severe postoperative complications (Dindo-Clavien>II) were present in 13% of the patients. Albumin less than 32 g/l was associated with a five-fold increase in severe complications (P=0.039; hazard ratio=4.9; 95% confidence interval: 1-22). Up to 35% of the patients needed no further medical treatment during the first 5 years postoperatively. CONCLUSION: In this cohort, the majority of patients with penetrating ileal CD underwent surgery. The presence of an abscess showed a significant association with the need for surgery. There was an acceptable postoperative complication rate. Patients with low albumin had an unfavourable postoperative course. The long-term outcome after surgery was favourable. PMID- 29462030 TI - Refining Risk Adjustment for the Proposed CMS Surgical Hip and Femur Fracture Treatment Bundled Payment Program. AB - BACKGROUND: The U.S. Centers for Medicare & Medicaid Services (CMS) has been considering the implementation of a mandatory bundled payment program, the Surgical Hip and Femur Fracture Treatment (SHFFT) model. However, bundled payments without appropriate risk adjustment may be inequitable to providers and may restrict access to care for certain patients. The SHFFT proposal includes adjustment using the Diagnosis-Related Group (DRG) and geographic location. The goal of the current study was to identify and quantify patient factors that could improve risk adjustment for SHFFT bundled payments. METHODS: We retrospectively reviewed a 5% random sample of Medicare data from 2008 to 2012. A total of 27,898 patients were identified who met SHFFT inclusion criteria (DRG 480, 481, and 482). Reimbursement was determined for each patient over the bundle period (the surgical hospitalization and 90 days of post-discharge care). Multivariable regression was performed to test demographic factors, comorbidities, geographic location, and specific surgical procedures for associations with reimbursement. RESULTS: The average reimbursement was $23,632 +/- $17,587. On average, reimbursements for male patients were $1,213 higher than for female patients (p < 0.01). Younger age was also associated with higher payments; e.g., reimbursement for those >=85 years of age averaged $2,282 +/- $389 less than for those aged 65 to 69 (p < 0.01). Most comorbidities were associated with higher reimbursement, but dementia was associated with lower payments, by an average of $2,354 +/- $243 (p < 0.01). Twenty-two procedure codes are included in the bundle, and patients with the 3 most common codes accounted for 98% of the cases, with average reimbursement ranging from $22,527 to $24,033. Less common procedures varied by >$20,000 in average reimbursement (p < 0.01). DRGs also showed significant differences in reimbursement (p < 0.01); e.g., DRG 480 was reimbursed by an average of $10,421 +/- $543 more than DRG 482. Payments varied significantly by state (p <= 0.01). Risk adjustment incorporating specific comorbidities demonstrated better performance than with use of DRG alone (r = 0.22 versus 0.15). CONCLUSIONS: Our results suggest that the proposed SHFFT bundled payment model should use more robust risk-adjustment methods to ensure that providers are reimbursed fairly and that patients retain access to care. At a minimum, payments should be adjusted for age, comorbidities, demographic factors, geographic location, and surgical procedure. PMID- 29462029 TI - Patient tolerance and acceptance of different colonic imaging modalities: an observational cohort study. AB - BACKGROUND: Less invasive alternatives to optical colonoscopy (OC) may improve patient compliance with investigation, but study of patient preference is limited. OBJECTIVES: The aims of this study were to determine patient tolerance and acceptability of OC, computed tomography colonography (CTC) and colon capsule endoscopy (CCE) and also to determine the choice of investigation made by fully informed members of the lay public. PATIENTS AND METHODS: Patients assigned a Gloucester Comfort Score (GCS, 1-5; as did endoscopists), an overall test experience score (visual analogue scale, 0-10) and completed a 'Friends and Family Test' following OC, CTC or CCE. In the second part of the study, members of the public were given information detailing the nature, tolerance, acceptability, risks and outcomes and invited to choose which test they would prefer in the event that one was needed. RESULTS: Assessed by endoscopist and patient, respectively, 24.2 and 49.3% (P<0.005) of symptomatic and 27.3 and 22.1% (P=0.4) of Bowel Cancer Screening Programme patients suffered moderate to severe discomfort (GCS: 4-5) [GCS (mean+/-SEM): 3.32+/-0.085, 1.96+/-0.083 and 1.30+/ 0.088 (P<0.001); overall experience: 5.43, 2.35 and 3.80 (P<0.001)]. In all, 93.6, 96.1 and 85.7% of OC, CTC and CCE patients, respectively, were willing to undergo the same test under the same circumstances. The lay public (n=100) chose a noninvasive test (CTC or CCE) in 55% of the cases to investigate symptoms and chose a Bowel Cancer Screening Programme test in 29% of the cases (P<0.001). CONCLUSION: Patient tolerance and experience favours CTC and CCE over OC and informed about all aspects of each procedure; a noninvasive option is commonly chosen by the lay public. PMID- 29462031 TI - Minimum Two-Year Follow-up of Anterior Cruciate Ligament Reconstruction in Patients with Generalized Joint Laxity. AB - BACKGROUND: The purposes of this investigation were to compare outcomes of anterior cruciate ligament (ACL) reconstruction between patients with generalized joint laxity and those without it and to investigate the effect of generalized joint laxity on outcomes of ACL reconstruction from 2 to 8 years postoperatively. METHODS: We retrospectively reviewed 163 patients who had undergone unilateral ACL reconstruction from January 2001 to December 2008. Patients were divided into 2 groups according to presence or absence of generalized joint laxity. The proportions of patients with meniscectomy, graft rupture, and contralateral ACL rupture were compared. Rupture rates were compared with Kaplan-Meier analysis. The Lachman test, pivot-shift test, and anterior translation measured with the KT 2000 arthrometer were evaluated. The Lysholm knee score and International Knee Documentation Committee (IKDC) subjective score were compared. The IKDC objective grade and radiographic grade were also evaluated. Follow-up assessments were performed at 2, 5, and 8 years postoperatively. RESULTS: The proportions of meniscectomy, graft rupture, and contralateral ACL rupture in patients with generalized joint laxity were higher than in patients without generalized joint laxity during the whole evaluation period. However, differences in proportions and cumulative rupture rates did not reach significance (p > 0.05). Patients with generalized joint laxity had less stability and poorer functional outcomes at the 8-year follow-up compared with patients without generalized joint laxity. With regard to the Lachman test and anterior translation, poorer results were shown in patients with generalized joint laxity than in patients without generalized joint laxity during the whole evaluation period. The results of pivot-shift testing differed significantly at 5 years (p = 0.002) and 8 years (p = 0.007). Patients with generalized joint laxity also had worse Lysholm knee scores and IKDC subjective scores during the whole evaluation period; these differences may not be clinically important. Comparisons between serial outcomes measured at 2, 5, and 8-year follow-ups within each patient group showed that anterior translation (p = 0.002), Lysholm knee score (p = 0.014), and IKDC subjective score (p = 0.002) deteriorated over time, although the values at 8 years were similar to those at 5 years, in patients with generalized joint laxity. CONCLUSIONS: Generalized joint laxity as an inherent physiologic characteristic of patients was related to a significant adverse effect on stability and functional outcomes of ACL reconstruction for patients followed for 2 to 8 years. Generalized joint laxity should be considered a risk factor for poor outcomes after ACL reconstruction. LEVEL OF EVIDENCE: Therapeutic Level III.

PMID- 29462032 TI - Perioperative Allogeneic Red Blood-Cell Transfusion Associated with Surgical Site Infection After Total Hip and Knee Arthroplasty. AB - BACKGROUND: Perioperative allogeneic red blood-cell transfusion is a suspected risk factor for surgical site infection (SSI) after total joint arthroplasty (TJA), but the interrelationships among SSI risk, transfusion dose, preoperative anemia, and the presence of coagulopathies have not been well described. METHODS: Data on SSI within 1 year after surgery as well as on transfusion with blood products within 30 days after surgery were obtained for 6,788 patients who had undergone primary or revision total hip or knee arthroplasty from 2000 to 2011 in a single hospital system. Multivariate logistic regression modeling was used to determine the independent association between allogeneic red blood-cell transfusion and SSI. RESULTS: There was a dose-dependent association between allogeneic red blood-cell transfusion and SSI, with the infection rate increasing as the transfusion dose increased from 1 unit (odds ratio [OR] = 1.97; 95% confidence interval [CI] = 1.38, 2.79; p < 0.001), to 2 units (OR = 2.20; CI = 1.37, 3.44; p = 0.002), to 3 units (OR = 3.66; CI = 1.72, 7.16; p = 0.001), and to >3 units (OR = 7.40; CI = 4.91, 11.03; p < 0.001) after controlling for medical comorbidities, planned procedure, preoperative anemia, and preexisting coagulopathies. A preexisting bleeding disorder (OR = 2.09; CI = 1.57, 2.80; p < 0.001) and clotting disorder (OR = 1.37; CI = 1.14, 1.64; p = 0.001) and preoperative anemia (OR = 3.90; CI = 3.31, 4.61; p < 0.001) were all independent risk factors for transfusion after adjusting for the planned procedure. CONCLUSIONS: We found a dose-dependent relationship between allogeneic red blood cell transfusion and SSI risk after total hip or knee arthroplasty. Additionally, preoperative anemia or a known bleeding or clotting disorder were risk factors for the need for allogeneic red blood-cell transfusion. Our findings underscore the need for preoperative risk assessment, methods to limit surgical tissue injury, and optimized blood conservation strategies. LEVEL OF EVIDENCE: Therapeutic Level III.

PMID- 29462033 TI - Low-Dose Epinephrine Plus Tranexamic Acid Reduces Early Postoperative Blood Loss and Inflammatory Response: A Randomized Controlled Trial. AB - BACKGROUND: The reductions of perioperative blood loss and inflammatory response are important in total knee arthroplasty. Tranexamic acid reduced blood loss and the inflammatory response in several studies. However, the effect of epinephrine administration plus tranexamic acid has not been intensively investigated, to our knowledge. In this study, we evaluated whether the combined administration of low dose epinephrine plus tranexamic acid reduced perioperative blood loss or inflammatory response further compared with tranexamic acid alone. METHODS: This randomized placebo-controlled trial consisted of 179 consecutive patients who underwent primary total knee arthroplasty. Patients were randomized into 3 interventions: Group IV received intravenous low-dose epinephrine plus tranexamic acid, Group TP received topical diluted epinephrine plus tranexamic acid, and Group CT received tranexamic acid alone. The primary outcome was perioperative blood loss on postoperative day 1. Secondary outcomes included perioperative blood loss on postoperative day 3, coagulation and fibrinolysis parameters (measured by thromboelastography), inflammatory cytokine levels, transfusion values (rate and volume), thromboembolic complications, length of hospital stay, wound score, range of motion, and Hospital for Special Surgery (HSS) score. RESULTS: The mean calculated total blood loss (and standard deviation) in Group IV was 348.1 +/- 158.2 mL on postoperative day 1 and 458.0 +/- 183.4 mL on postoperative day 3, which were significantly reduced (p < 0.05) compared with Group TP at 420.5 +/- 188.4 mL on postoperative day 1 and 531.1 +/- 231.4 mL on postoperative day 3 and Group CT at 520.4 +/- 228.4 mL on postoperative day 1 and 633.7 +/- 237.3 mL on postoperative day 3. Intravenous low-dose epinephrine exhibited a net anti-inflammatory activity in total knee arthroplasty and did not induce an obvious hypercoagulable status. Transfusion values were significantly reduced (p < 0.05) in Group IV, but no significant differences were observed in the incidence of thromboembolic complications, wound score, range of motion, and HSS score among the 3 groups (p > 0.05). CONCLUSIONS: The combined administration of low-dose epinephrine and tranexamic acid demonstrated an increased effect in reducing perioperative blood loss and the inflammatory response compared with tranexamic acid alone, with no apparent increased incidence of thromboembolic and other complications.

PMID- 29462034 TI - Acute Thoracolumbar Spinal Cord Injury: Relationship of Cord Compression to Neurological Outcome. AB - BACKGROUND: Spinal cord injury in the cervical spine is commonly accompanied by cord compression and urgent surgical decompression may improve neurological recovery. However, the extent of spinal cord compression and its relationship to neurological recovery following traumatic thoracolumbar spinal cord injury is unclear. The purpose of this study was to quantify maximum cord compression following thoracolumbar spinal cord injury and to assess the relationship among cord compression, cord swelling, and eventual clinical outcome. METHODS: The medical records of patients who were 15 to 70 years of age, were admitted with a traumatic thoracolumbar spinal cord injury (T1 to L1), and underwent a spinal surgical procedure were examined. Patients with penetrating injuries and multitrauma were excluded. Maximal osseous canal compromise and maximal spinal cord compression were measured on preoperative mid-sagittal computed tomography (CT) scans and T2-weighted magnetic resonance imaging (MRI) by observers blinded to patient outcome. The American Spinal Injury Association (ASIA) Impairment Scale (AIS) grades from acute hospital admission (<=24 hours of injury) and rehabilitation discharge were used to measure clinical outcome. Relationships among spinal cord compression, canal compromise, and initial and final AIS grades were assessed via univariate and multivariate analyses. RESULTS: Fifty-three patients with thoracolumbar spinal cord injury were included in this study. The overall mean maximal spinal cord compression (and standard deviation) was 40% +/- 21%. There was a significant relationship between median spinal cord compression and final AIS grade, with grade-A patients (complete injury) exhibiting greater compression than grade-C and D patients (incomplete injury) (p < 0.05). Multivariate logistic regression identified mean spinal cord compression as independently influencing the likelihood of complete spinal cord injury (p < 0.01). CONCLUSIONS: Traumatic thoracolumbar spinal cord injury is commonly accompanied by substantial cord compression. Greater cord compression is associated with an increased likelihood of severe neurological deficits (complete injury) following thoracolumbar spinal cord injury.

PMID- 29462035 TI - Conventional Primary Central Chondrosarcoma of the Pelvis: Prognostic Factors and Outcome of Surgical Treatment in 162 Patients. AB - BACKGROUND: Studies focusing on the oncological outcome after treatment of conventional primary central chondrosarcoma of pelvic bone are lacking. We conducted this retrospective study at 5 referral centers to gain insight in the outcome of treatment for this tumor type and to identify risk factors for impaired oncological outcome. METHODS: One hundred and sixty-two consecutive patients (118 male patients [73%]) who underwent resection of a conventional primary central chondrosarcoma of pelvic bone from 1985 to 2013 were evaluated. The median age was 51 years (range, 15 to 78 years). The median follow-up was 12.6 years (95% confidence interval [CI], 8.4 to 16.9 years). There were 30 grade I lesions (19%), 93 grade-II lesions (57%), and 39 grade-III lesions (24%). RESULTS: Sixty-two patients (38%) experienced local recurrence: 9 grade-I lesions (30%), 31 grade-II lesions (33%), and 22 grade-III lesions (56%). Forty-eight patients (30%) developed metastases. The risk of disease-related death was 3% for grade-I tumors (1 of 30; this patient had a grade-II recurrence and died of metastases), 33% (31 of 93) for grade-II tumors, and 54% (21 of 39) for grade-III tumors. Identified risk factors for impaired disease-specific survival were tumor grade (grade II: hazard ratio [HR], 20.18; p = 0.003; and grade III: HR, 58.94; p < 0.001), resection margins (marginal: HR, 3.21; p = 0.001; and intralesional: HR, 3.56; p < 0.001), and maximal tumor size (HR, 1.08 per cm; p = 0.026). Deep infection (19% [n = 31]) was the predominant complication. CONCLUSIONS: This study offers a standard for survival rates for conventional primary central chondrosarcoma of the pelvis. The survival for grade-I tumors was excellent. Wide resection margins were associated with a significant survival advantage for higher-grade tumors. Because of the inability to reliably distinguish low-grade and high-grade tumors preoperatively, we conclude that any central pelvic chondrosarcoma should be treated with aggressive primary resection with the aim of obtaining wide resection margins. There may be aggressive biologic features in some tumors for which a surgical procedure alone may not be adequate to improve outcomes. LEVEL OF EVIDENCE: Therapeutic Level IV.

PMID- 29462036 TI - The Cost of Joint Replacement: Comparing Two Approaches to Evaluating Costs of Total Hip and Knee Arthroplasty. AB - BACKGROUND: In an era of mandatory bundled payments for total joint replacement, accurate analysis of the cost of procedures is essential for orthopaedic surgeons and their institutions to maintain viable practices. The purpose of this study was to compare traditional accounting and time-driven activity-based costing (TDABC) methods for estimating the total costs of total hip and knee arthroplasty care cycles. METHODS: We calculated the overall costs of elective primary total hip and total knee replacement care cycles at our academic medical center using traditional and TDABC accounting methods. We compared the methods with respect to the overall costs of hip and knee replacement and the costs for each major cost category. RESULTS: The traditional accounting method resulted in higher cost estimates. The total cost per hip replacement was $22,076 (2014 USD) using traditional accounting and was $12,957 using TDABC. The total cost per knee replacement was $29,488 using traditional accounting and was $16,981 using TDABC. With respect to cost categories, estimates using traditional accounting were greater for hip and knee replacement, respectively, by $3,432 and $5,486 for personnel, by $3,398 and $3,664 for space and equipment, and by $2,289 and $3,357 for indirect costs. Implants and consumables were derived from the actual hospital purchase price; accordingly, both methods produced equivalent results. CONCLUSIONS: Substantial cost differences exist between accounting methods. The focus of TDABC only on resources used directly by the patient contrasts with the allocation of all operating costs, including all indirect costs and unused capacity, with traditional accounting. We expect that the true costs of hip and knee replacement care cycles are likely somewhere between estimates derived from traditional accounting methods and TDABC. TDABC offers patient-level granular cost information that better serves in the redesign of care pathways and may lead to more strategic resource-allocation decisions to optimize actual operating margins. PMID- 29462037 TI - The Free-Hand Technique for S2-Alar-Iliac Screw Placement: A Safe and Effective Method for Sacropelvic Fixation in Adult Spinal Deformity. AB - BACKGROUND: Spinopelvic fixation is an integral part of achieving solid fusion across the lumbosacral junction, especially in deformity procedures requiring substantial correction or long-segment constructs. Traditional S2-alar-iliac (S2AI) screw-placement techniques utilize fluoroscopy, increasing operative time and radiation exposure to the patient and surgeon. We describe a novel free-hand technique for S2AI screw placement in patients with adult spinal deformity. METHODS: We reviewed the records of 45 consecutive patients who underwent spinopelvic fixation performed with use of S2AI screws by the senior surgeon and various fellows or residents over a 12-month period (2015 to 2016). In each case, the S2AI screws were placed utilizing a free-hand technique without fluoroscopic or image guidance. Screw position and accuracy were assessed by intraoperative O arm imaging and analyzed using 3-dimensional interactive manipulation of computed tomography images. RESULTS: A total of 100 screws were placed, 51 by the senior surgeon and 49 by trainees. The mean patient age was 57.4 +/- 12.7 years at the time of surgery; 37 (82.2%) of the patients were female. Preoperative diagnoses included adult idiopathic scoliosis (n = 19), adult degenerative scoliosis (n = 15), flatback syndrome (n = 2), fixed sagittal imbalance (n = 6), and distal junctional kyphosis (n = 3). Five (5%) of the screws were placed with moderate to severe cortical breaches, all of which perforated the pelvis posteriorly, with no clinically notable neurovascular or visceral complications. The breach rate did not differ significantly between the senior surgeon and trainees. CONCLUSIONS: The free-hand technique for S2AI screw placement, when performed in a standardized manner, was demonstrated to be safe and reliable in constructs requiring spinopelvic fixation. The accuracy of screw placement relies on visible and palpable anatomic landmarks that obviate the need for intraoperative fluoroscopy or image guidance, potentially reducing operative time and radiation exposure.

PMID- 29462039 TI - Not Using a Tourniquet During Anterior Ankle Arthroscopy Did Not Affect Postoperative Intra-Articular Bleeding or Function at Six Months. PMID- 29462038 TI - The Creation and Validation of a Knee Bone Age Atlas Utilizing MRI. AB - BACKGROUND: In managing many pediatric knee conditions, an accurate bone age assessment may be critical for diagnostic, prognostic, and treatment purposes. The aim of this study was to create an atlas of magnetic resonance imaging (MRI) studies of the knee spanning the pediatric and adolescent years that would enable accurate skeletal age to be assessed, potentially forgoing the need for a left hand radiograph. METHODS: We performed a retrospective assessment of 11 to 31 MRIs from male and female patients of each age from 2 to 19 years. Radiographic features specific to the patella, tibia, fibula, and femur were documented with respect to their presence or absence. From these data, age and sex "standards" were established, allowing the creation on an atlas. A separate cohort of MRIs with 2 to 13 patients per age and sex was then used to validate the reliability and reproducibility of the atlas. RESULTS: In the creation of the atlas, a total of 859 MRIs were reviewed. The patella, tibia, fibula, and femur were noted to undergo a reproducible sequence of skeletal ossification. The patella provided the best age assessment in early childhood. Features specific to the tibia, particularly ossification of the tibial spine and the tibial tubercle, were of particular importance in children between the ages of 6 and 12 years. MRI features of the fibula and femur served a more important role in age assessment later in skeletal maturity. From a separate cohort of 323 MRIs utilized to validate the atlas, a strong correlation between chronologic age and bone age was shown, as was excellent interobserver and intraobserver reliability. CONCLUSIONS: The predictable ossification pattern of the patella, tibia, fibula, and femur enables accurate bone age calculations to be made from knee MRIs. When treating conditions about the knee that require MRI, obtaining an additional left-hand radiograph for bone age may be unnecessary. This information can be used to potentially avoid additional radiation exposure, impart cost savings, and lead to greater clinic efficiency.

PMID- 29462043 TI - Equal Pay for Equal Work: Medicare Procedure Volume and Reimbursement for Male and Female Surgeons Performing Total Knee and Total Hip Arthroplasty. AB - BACKGROUND: The observed sex gap in physician salary has been the topic of much recent debate in the United States, but it has not been well-described among orthopaedic surgeons. The objective of this study was to evaluate for sex differences in Medicare claim volume and reimbursement among orthopaedic surgeons. METHODS: The Medicare Provider Utilization and Payment Public Use File was used to compare claim volume and reimbursement between female and male orthopaedic surgeons in 2013. Data were extracted for each billing code per orthopaedic surgeon in the year 2013 for total claims, surgical claims, total knee arthroplasty (TKA) claims, and total hip arthroplasty (THA) claims. RESULTS: A total of 20,546 orthopaedic surgeons who treated traditional Medicare patients were included in the initial analysis. Claim volume and reimbursement received were approximately twofold higher for all claims and more than threefold higher for surgical claims for male surgeons when compared with female surgeons (p < 0.001 for all comparisons). A total of 7,013 and 3,839 surgeons performed >10 TKAs and THAs, respectively, in 2013 for Medicare patients and were included in the subset analyses. Although male surgeons performed a higher mean number of TKAs than female surgeons (mean and standard deviation, 37 +/- 33 compared with 26 +/- 17, respectively, p < 0.001), the claim volume for THAs was similar (29 +/ 22 compared with 24 +/- 13, respectively, p = 0.080). However, there was no significant difference in mean reimbursement payments received per surgeon between men and women for TKA or THA ($1,135 +/- $228 compared with $1,137 +/- $184 for TKA, respectively, p = 0.380; $1,049 +/- $226 compared with $1,043 +/- $266 for THA, respectively, p = 0.310). CONCLUSIONS: Female surgeons had a lower number of total claims and reimbursements compared with male surgeons. However, among surgeons who performed >10 THAs and TKAs, there were no sex differences in the mean reimbursement payment per surgeon. CLINICAL RELEVANCE: The number of women in orthopaedics is rising, and there is much interest in how their productivity and compensation compare with their male counterparts.

AB - Appropriateness classification for total knee arthroplasty (TKA) has received substantial attention recently, and Katz and colleagues published an Orthopaedic Forum on the topic in The Journal of Bone & Joint Surgery in February 2017. Classifications of appropriateness are particularly important given the rapid rise in use of TKA and a variety of third-party payer approaches designed to control health-care costs. We respond to some of the concerns addressed by Katz and colleagues, and elaborate on what we believe are some important issues related to both older and newer appropriateness criteria for TKA.

PMID- 29462049 TI - Suprasternal Transcatheter Aortic Valve Replacement in Patients With Marginal Femoral Access. AB - OBJECTIVE: Recently, the PARTNER 2A trial reported results of transcatheter aortic valve replacement versus surgical aortic valve replacement in 2032 intermediate-risk patients at 2 years. Two hundred thirty-six patients (24%) required an access route other than transfemoral. Compared with transfemoral and surgical aortic valve replacement, nontransfemoral transcatheter aortic valve replacement was associated with a numerically higher rate of death and disabling stroke at 30 days. This underscores the need for a better alternative surgical approach for patients with marginal femoral access. We reviewed our multicenter experience with minimally invasive suprasternal transcatheter aortic valve replacement. METHODS: Consecutive patients with symptomatic severe aortic stenosis at high or intermediate risk for surgical aortic valve replacement underwent suprasternal transcatheter aortic valve replacement. A commercially available transcatheter heart valve was deployed under fluoroscopic guidance through the innominate artery or ascending aorta. Using a 3-cm skin incision just above the sternal notch, the Aegis Transit System (Aegis Surgical Ltd, Galway, Ireland) provided illuminated access to the mediastinum without bone disruption. Through a purse-string suture placed in the innominate artery or ascending aorta, transcatheter aortic valve replacement proceeded similarly to the direct aortic approach. RESULTS: Thirty patients at six medical centers successfully underwent suprasternal transcatheter aortic valve replacement. Implanted valves included 2 CoreValve and 12 Evolut-R (Medtronic, Inc, Minneapolis, MN USA), as well as 10 SAPIEN 3 and 6 SAPIEN XT (Edwards Lifesciences, Corp, Irvine, CA USA) with sizes ranging from 23 to 31 mm. Median procedure time was 90 minutes and median hospital stay was 4 days. Postoperatively, new permanent pacemaker (n = 3) was the most common Vascular Academic Research Consortium 2 complication. CONCLUSIONS: These data demonstrate the early clinical feasibility of suprasternal transcatheter aortic valve replacement. Key advantages of this approach include direct access to the innominate artery and ascending aorta, precise sheath control, and confident arterial closure. Additional experience is warranted to confirm these favorable results. PMID- 29462050 TI - Acute Heart Failure at the Time of Transcatheter Aortic Valve Replacement Does Not Increase Mortality. AB - OBJECTIVE: Patients presenting for transcatheter aortic valve replacement are often in acute on chronic heart failure, as indicated by elevated N-terminal pro B-type natriuretic peptide. Many believe that elevated N-terminal pro-B-type natriuretic peptide is an indication to treat medically, reserving surgery until the patient is medically optimized. METHODS: A single-center transcatheter aortic valve replacement database was queried from December 2015 to November 2016 to identify patients undergoing transcatheter aortic valve replacement. Patients were divided into two cohorts based on preoperative N-terminal pro-B-type natriuretic peptide level. An analysis was then completed to assess outcomes such as length of intensive care unit stay, total length of stay, discharge to home, major complications, and mortality at 30 days. RESULTS: There were 142 patients (median age = 80 years, 44% female) with preoperative N-terminal pro-B-type natriuretic peptide data included (range = 106-73,500 pg/mL). The mean Society of Thoracic Surgeons predicative risk of mortality was 8%, and 46 patients (32%) had N-terminal pro-B-type natriuretic peptide of greater than 3000 pg/mL. N-terminal pro-B-type natriuretic peptide of greater than 3000 pg/mL was associated only with increased intensive care unit length of stay of greater than 24 hours (35% vs 9%, P = 0.0001). There was no statistical difference between cohorts with regard to total length of stay of greater than 3 days (24% vs 15%, P = 0.2), discharge to home (74% vs 83%, P = 0.3), major complication, or mortality at 30 days. CONCLUSIONS: Transcatheter aortic valve replacement is an appropriate and effective treatment for patients with aortic stenosis presenting with high N terminal pro-B-type natriuretic peptide and acute on chronic heart failure. PMID- 29462051 TI - Long-Term Outcome of Patients Undergoing Minimally Invasive Direct Coronary Artery Bypass Surgery: A Single-Center Experience. AB - OBJECTIVE: The primary objective was to investigate the long-term survival of patients who underwent single-vessel coronary revascularization with minimally invasive direct coronary artery bypass surgery with or without hybrid revascularization. The secondary outcome measures were repeat revascularization either by coronary artery bypass grafting or by percutaneous coronary intervention and the incidence of myocardial infarction or recurrent angina. METHODS: This is a retrospective study of prospectively collected data of patients who underwent minimally invasive direct coronary artery bypass procedure in our center between January 2001 and December 2015. Procedures were performed either through small left anterolateral thoracotomy or lower midline sternotomy. RESULTS: A total of 182 patients were identified: 100 underwent minimally invasive direct coronary artery bypass to the left anterior descending artery and 82 underwent hybrid revascularization (percutaneous coronary intervention to coronary arteries other than the left anterior descending artery along with minimally invasive direct coronary artery bypass to the left anterior descending artery). The mean +/- SD age was 62 +/- 10.1 years. Preoperatively 82% were male, and 72.5% patients had good left ventricular function. The median follow-up period was 10.9 years. There was no in-hospital or 30-day mortality. The 10-year actuarial survival was 84.8%. Freedom from repeat revascularization was 98.9% at 1 year and 89.9% at 10 years. At follow-up, freedom from myocardial infarction was 96.7% whereas freedom from angina was 92.9%. CONCLUSIONS: Within the limitations imposed by retrospective analyses, our study demonstrates excellent long-term outcome in patients undergoing minimally invasive direct coronary artery bypass with or without hybrid revascularization. For isolated left anterior descending artery disease minimally invasive direct coronary artery bypass should be considered, whereas hybrid revascularization (percutaneous coronary intervention and minimally invasive direct coronary artery bypass) should be considered for multivessel disease. PMID- 29462052 TI - Does Robotic Beating Heart Connector Totally Endoscopic Coronary Artery Bypass Bridge the Gender Gap in Coronary Bypass Surgery? AB - OBJECTIVE: Previous studies have shown that women carry a higher risk of morbidity and mortality after coronary artery bypass surgery. We investigated gender differences in risk factors and outcomes in our patients undergoing robotic beating heart connector totally endoscopic coronary artery bypass. METHODS: From July 2013 to April 2017, patients undergoing connector totally endoscopic coronary artery bypass were reviewed. We compared the outcomes of men versus women. RESULTS: A total of 192 men and 71 women underwent connector totally endoscopic coronary artery bypass. The mean +/- SD age was 65.4 +/- 10.6 years. The Society of Thoracic Surgeons score was higher in women than men (median = 1.46 vs 0.73, P = 0.001), and women had a higher rate of peripheral vascular disease (22.5% vs 9.9%, P = 0.007). Intraoperative data in women and men were similar except for the rate of multi-vessel connector totally endoscopic coronary artery bypass and the rate of bilateral internal mammary artery use, which were both lower in women (49.3% vs 64.6%, P = 0.024, and 42.3% vs 56.8%, P = 0.036, respectively). The mean +/- SD length of hospital stay (women vs men: 3.99 +/- 4.00 vs 3.39 +/- 2.42, P = 0.324) was comparable. The 30-day mortality in women and men was 0% (0/71) and 2.1% (4/192), respectively (P = 0.577). The morbidity and mortality of single- or multi-vessel connector totally endoscopic coronary artery bypass were similar between men and women. CONCLUSIONS: We conclude that the morbidity and mortality in women after robotic beating heart connector totally endoscopic coronary artery bypass in our center were similar to those seen in men. PMID- 29462053 TI - Vitamin K antagonists and emergencies. AB - The recent emergence of 'non-VKA' oral anticoagulants may have led to some forgetting that vitamin K antagonists (VKA) are by far the most widely prescribed oral anticoagulants worldwide. Consequently, we decided to summarize the information available on them. This paper presents the problems facing emergency physicians confronted with patients on VKAs in 10 points, from pharmacological data to emergency management. Vitamin K antagonists remain preferable in many situations including in the elderly, in patients with extreme body weights, severe chronic kidney or liver disease or valvular heart disease, and in patients taking VKAs with well-controlled international normalized ratios (INRs). Given the way VKAs work, a stable anticoagulant state can only be achieved at the earliest 5 days after starting therapy. The induction phase of VKA treatment is associated with the highest risk of bleeding; validated algorithms based on INR values have to be followed. VKA asymptomatic overdoses and 'non-severe' hemorrhage are managed by omitting a dose or stopping treatment plus administering vitamin K depending on the INR. Major bleeding is managed using a VKA reversal strategy. A prothrombin complex concentrate infusion plus vitamin K is preferred to rapidly achieve an INR of up to 1.5 and maintain a normal coagulation profile. The INR must be measured 30 min after the infusion. Before an invasive procedure, if an INR of less than 1.5 (<1.3 in neurosurgery) is required, it can be achieved by combining prothrombin complex concentrate and vitamin K. A well-codified strategy is essential for managing patients requiring emergency invasive procedures or presenting bleeding complications.

PMID- 29462057 TI - Segmental Spinal Myoclonus Complicating Lumbar Transforaminal Epidural Steroid Injection. AB - OBJECTIVE: Lumbar transforaminal epidural steroid injection is commonly used for treating lumbar radicular pain. We report a case of segmental spinal myoclonus that developed during lumbar transforaminal epidural injection with local anesthetic and steroid. CASE REPORT: A 58-year-old woman with failed back surgery syndrome presented with low back and right L3 and L4 radicular pain. As she had responded well previously to diagnostic selective nerve root injection with local anesthetic at the right L3 and L4 levels, lumbar transforaminal epidural steroid injection at the same levels was scheduled. During injection of ropivacaine and triamcinolone at the right L3-4 intervertebral foramen, she complained of back pain and immediately developed involuntary contraction of her right hip. The procedure was terminated. No new neurological deficit was detected when she was examined 15 minutes after the procedure. There were no abnormalities from blood tests and magnetic resonance imaging of the lower thoracic and lumbar spine. A neurologist subsequently made the clinical diagnosis of segmental spinal myoclonus. The myoclonus improved over 1 month and eventually resolved completely. CONCLUSIONS: Segmental spinal myoclonus is a rare complication after lumbar transforaminal epidural steroid and local anesthetic injection. Pain physicians should be aware of this potential complication.

AB - BACKGROUND AND OBJECTIVES: Paravertebral block (PVB) is an established technique for providing anesthesia for breast surgery. The primary objective was to compare anatomical landmark technique (ALT) to the ultrasound-guided (USG) PVB block for providing surgical anesthesia. Secondary objectives included comparison of perioperative analgesia and complications. METHODS: This randomized, controlled, observer-blinded study included 72 females, aged 18 to 65 years, American Society of Anesthesiologists physical status I or II, undergoing elective unilateral breast surgery. Study participants were randomized to the ALT group or USG group. Ipsilateral PVB was performed with the respective technique from T1 to T6. Five milliliters of local anesthetic mixture (0.5% ropivacaine, 5 MUg/mL adrenaline, 1 MUg/kg clonidine) was administered at each level. Paravertebral catheter was inserted at T4/T3 level. After confirming sensory loss, patients were taken up for surgery with propofol sedation (20-50 MUg/kg per minute). RESULTS: More patients in the USG group (34/36 [94.44%]) had a successful block as compared with the ALT group (26/36 [72.22%]) (P = 0.024). Difference in proportion was 18.1 (95% confidence interval, 0.15-36.0) (P = 0.024) after adjustment for age. More dermatomes were blocked in the USG group (P = 0.0018) with less sparing of upper T2 and T3 dermatomes (P = 0.003, P = 0.006, respectively). Median time to first postoperative analgesic requirement was 502.5 minutes (range, 195-1440 minutes) in the USG group versus 377.5 minutes (range, 215-1440 minutes) in the ALT group. Pain at rest and movement 2 and 4 hours postoperatively and number of catheter top-ups in 24 hours postoperatively were lesser in the USG group (P = 0.012). Complications were comparable. CONCLUSIONS: Ultrasound-guided PVB provided better anesthesia and perioperative analgesia than the landmark technique for breast surgery. CLINICAL TRIAL REGISTRATION: The trial was registered retrospectively at the Clinical Trial Registry of India, CTRI/2015/05/005774. PMID- 29462059 TI - Effects of Ultra-early Hyperbaric Oxygen Therapy on Femoral Calcitonin Gene Related Peptide and Bone Metabolism of Rats With Complete Spinal Transection. AB - STUDY DESIGN: Seventy-five Sprague-Dawley rats were randomly divided into sham, complete spinal cord transection (CSCT) and hyperbaric oxygen (HBO) groups. Among them, rats in HBO group were further divided into 3 hours group (HBO1) and 12 hours group (HBO2). OBJECTIVE: To study the effects of ultra-early HBO therapy on femoral calcitonin gene-related peptide (CGRP) and bone metabolism of rats with CSCT. SUMMARY OF BACKGROUND DATA: Complete spinal cord injury (SCI) is still an unresolved problem in clinical practice. Studies on changes in (calcitonin gene related peptide) CGRP and bone metabolism and osteoporosis prevention after SCI have important clinical significance. METHODS: Rats in the sham group underwent laminectomy alone, whereas rats in the other three groups underwent laminectomy and CSCT at the level of the 10th thoracic vertebra. Six weeks after operation, rat blood samples and femoral samples from CSCT area were taken and prepared for immunohistochemical staining of CGRP, quantitative polymerase chain reaction (qPCR) of CGRP mRNA, enzyme-linked immunosorbent assay (ELISA) for the levels of serum bone-specific alkaline phosphatase (sBAP), serum osteocalcin (sOC), serum type-I collagen amino-terminal peptide (sNTX), and urinary deoxypyridinoline (uDPD). These data were statistically analyzed using paired LSD or Tamhane. RESULTS: The number of CGRP-positive cells and expression of CGRP mRNA in femur were significantly reduced, and the levels of sBAP, sOC, sNTX, and uDPD were significantly increased in CSCT, HBO1, and HBO2 groups than in the sham group, (P < 0.05-0.01). In addition, the number of CGRP-positive cells, expression of CGRP mRNA in femur, and the levels of sBAP and sOC were significantly enhanced, but the levels of sNTX and uDPD were significantly lowered in HBO1 group than in HBO2 and CSCT groups (P < 0.05). CONCLUSION: Ultra-early HBO therapy could improve bone turnover, promote bone formation, and prohibit bone resorption by enhancing CGRP synthesis in the sensory neurons in posterior horn of spinal cord.

PMID- 29462060 TI - Iliac Crest Bone Graft for Minimally Invasive Transforaminal Lumbar Interbody Fusion: A Prospective Analysis of Inpatient Pain, Narcotics Consumption, and Costs. AB - STUDY DESIGN: Retrospective Analysis OBJECTIVE.: The aim of this study was to determine whether an association between increased acute pain, postoperative time, and direct hospital costs exists between the use of iliac crest bone grafting (ICBG) and bone morphogenic protein (BMP)-2 following a primary, single level minimally invasive transforaminal lumbar interbody fusion (MIS TLIF). SUMMARY OF BACKGROUND DATA: ICBG has been associated with enhanced fusion rates. Concerns have been raised in regards to increased operative time and postoperative pain. The advantages of ICBG compared to other spinal fusion adjuncts have been debated. METHODS: Prospective, consecutive analysis of patients undergoing primary, single-level MIS TLIF with ICBG was compared to a historical cohort of consecutive patients that received BMP-2. Operative characteristics were compared between groups using chi analysis or independent t test for categorical and continuous variables, respectively. Postoperative inpatient pain was measured using the Visual Analog Scale, and inpatient narcotics consumption was quantified as oral morphine equivalents. Outcomes were compared between groups using multivariate regression controlling for preoperative characteristics. RESULTS: A total of 98 patients were included in this analysis, 49 in each cohort. No significant differences were noted between cohorts with exception to sex (Females: ICBG, 53.06% vs. BMP-2, 32.65%, P = 0.041). There was a significant increase in operative time (14.53 minutes, P = 0.006) and estimated blood loss (16.64 mL, P = 0.014) in the ICBG cohort. Narcotics consumption was similar between groups on postoperative days 0 and 1. ICBG was associated with decreased total direct costs ($19,315 vs. $21,645, P < 0.001) as compared to BMP-2. CONCLUSION: Patients undergoing MIS TLIF with ICBG experienced increases in operative time and estimated blood loss that were not clinically significant. Furthermore, iliac crest harvesting did not result in an increase in acute pain or narcotics consumption. Further follow-up is necessary to determine the associated arthrodesis rates and long-term outcomes between each cohort. LEVEL OF EVIDENCE: 3. PMID- 29462061 TI - Visual Loss Following Spine Surgery: What Have We Seen Within the Scoliosis Research Society Morbidity and Mortality Database? AB - STUDY DESIGN: A retrospective review of the Scoliosis Research Society (SRS) morbidity and mortality (M&M) database. OBJECTIVE: The aim of this study was to investigate visual related complications in spinal deformity patients undergoing spine surgery. SUMMARY OF BACKGROUND DATA: The SRS compiles surgeon-reported complications into an M&M database, tracking postoperative complications including visual loss, neurological deficits, infections, and death. Limited literature exists on postoperative visual complications, a rare but devastating complication following spine surgery. METHODS: We utilized the SRS M&M database to determine demographics, perioperative risk factors, and prognosis for visual related complications in spinal deformity patients undergoing corrective spine surgery from 2009 to 2012. RESULTS: A total of 167,972 spinal deformity patients from 2009 to 2012 were identified with a visual acuity complication (VAC) rate of 0.01%, or 12.5 per 100,000 patients. VAC rates for patients with kyphosis were significantly higher than patients with scoliosis (0.049% vs. 0.010%, P = 0.002) and spondylolisthesis (0.049% vs. 0.005%, P = 0.001). Postoperative visual loss rates significantly decreased from 2010 to 2012 (0.022% vs. 0.004%, P = 0.029). Twenty-one patients identified with VACs had a mean age of 34.8 +/- 24.3 years. Two (9.5%) patients had preoperative vision changes, two (9.5%) were diabetic, two (9.5%) had vascular disease, one (4.8%) had a history of thromboembolic disease, and five (23.8%) had hypertension. Extent of VAC was bilateral-partial in four (19.0%), bilateral-total in five (23.8%), unilateral-partial in eight (38.1%), and unilateral-total in three (14.3%) patients. Four (19.0%) patients developed anterior ischemic optic neuropathy, four (19.0%) had posterior ischemic optic neuropathy (PION), five (23.8%) had central retinal artery occlusion, and five (23.8%) developed cortical blindness (CB). Greater than 50% of the VACs occurred on, or before, the first postoperative day. Ten (47.6%) patients recovered complete vision and four (19.0%) improved. All patients with CB and 50% with posterior ischemic optic neuropathy experienced complete resolution. CONCLUSION: VACs occur in approximately 12.5 per 100,000 deformity patients, with a rate five times higher in patients with kyphosis. More than 50% of these complications occur within 24 hours postoperatively. Nearly half of these complications resolve completely, and another 19% improve postoperatively. LEVEL OF EVIDENCE: 4. PMID- 29462062 TI - Back Pain and Co-occurring Conditions: Findings From a Nationally Representative Sample. AB - STUDY DESIGN: Cross-sectional population-level health survey. OBJECTIVE: To describe the frequency of co-occurring conditions with back pain; to identify risk factors for back pain controlling for co-occurring conditions; and to examine the association between back pain and individual co-occurring conditions. SUMMARY OF BACKGROUND DATA: Back pain shares risk factors with a range of other conditions. Most studies have considered risk factors for back pain without taking into account the potential influence of co-occurring conditions. METHODS: Analysis of the 2013 Canadian Community Health Survey (n = 61,854, age >=15 yr). Back pain status and co-occurring conditions were determined from questions about long-term health conditions diagnosed by a health profession. Multivariable log Poisson regression analysis was used to assess the adjusted association of back pain with demographic and lifestyle characteristics and co-occurring conditions. RESULTS: The population prevalence of reported back pain was 19.3%. Most (71%) reported at least one co-occurring condition. Most frequently reported were arthritis (35%), high blood pressure (26%), migraine (18%), and mood disorders (14%). Following the addition of co-occurring condition count to the regression model, being female and being overweight/obese were no longer significantly associated with back pain, and the associations with ages 45 to 54 years and older, low-income, smoking, and being physical inactive were significantly attenuated. The highest prevalence ratio, 3.32 (95% confidence interval: 3.06 3.59), was for 3+ co-occurring conditions. In multivariable regression all but a few individual chronic conditions remained significant associated with back pain. CONCLUSION: Established risk factors for back pain may be largely a reflection of shared risk factors with co-occurring conditions. The high frequency of co occurring conditions likely reflects diverse mechanisms related to heterogeneity of back pain. The extent of association of co-occurring conditions with back pain has implications for clinical management and need for further research to characterize subgroups. LEVEL OF EVIDENCE: 2. PMID- 29462063 TI - Depression is Closely Associated With Chronic Low Back Pain in Patients Over 50 Years of Age: A Cross-sectional Study Using the Sixth Korea National Health and Nutrition Examination Survey (KNHANES VI-2). AB - STUDY DESIGN: A cross-sectional study. OBJECTIVE: This study was designed to analyze the relationship between the presence and severity of depression and low back pain (LBP) in a representative sample of the general population using a self report screening questionnaire for depression. SUMMARY OF BACKGROUND DATA: There is increasing evidence supporting an association between depression and LBP. However, the degree of the association between these two conditions in the general population is poorly understood. METHODS: Health surveys and examinations were conducted on a nationally representative sample (n = 7550) of Koreans. LBP status was determined by a simple survey response concerning LBP >30 days during the past 3 months. Depression was defined as individuals with a total score >10 on the Patient Health Questionnaire (PHQ)-9 survey. The severity of depression was categorized as none (0-4), mild (5-9), moderate (10-14), moderately severe (15-19), and severe (20-27) according to PHQ-9 score. Data regarding demographics, socioeconomic history, and comorbid health conditions were used to analyze adjusted, weighted logistic regression models. RESULTS: In the Korean population, the prevalence of depression was significantly greater in individuals with LBP (20.3%) than in those without LBP (4.5%). On multivariate logistic regression analysis, the presence of depression was significantly associated with LBP (adjusted odd ratio [aOR]: 3.93, P < 0.001). The risk of LBP increased with increasing severity of depression as follows: severe depression (aOR: 9.28, P < 0.001), moderately severe depression (aOR: 3.24, P = 0.001), moderate depression (aOR: 4.97, P < 0.001), and mild depression (aOR: 2.48, P < 0.001). CONCLUSION: Depression is more common in patients with LBP among Koreans. The presence of depression was significantly associated with LBP, especially in severely depressed individuals.

AB - STUDY DESIGN: A cross-sectional study OBJECTIVE.: The aim of this study was to study the health-related quality of life (HRQOL) of adolescents with severe untreated congenital kyphosis (CK) and congenital kyphoscoliosis (CKS) in a developing country. SUMMARY OF BACKGROUND DATA: Surgical intervention is generally indicated early in patients with progressive CK or CKS to prevent the progression of deformity and to improve the quality of life of the patients. HRQOL of adolescents with untreated CK and CKS in developing countries has never been investigated. METHODS: Arabic version of the Scoliosis Research Society 22 revision (SRS-22r) questionnaire used to study HRQOL of adolescents with severe untreated CK or CKS in a dev eloping country. RESULTS: A total of 134 adolescent (mean age 17.1 years) completed SRS-22r questionnaire: 38 patients with CK from 80 degrees to 110 degrees (group 1), 24 patients with CK > 110 degrees (group 2), 27 patients with CKS (group 3), and 45 healthy controls (group 4). Group 1 had significant lower scores than group 4 in all SRS 22r domains (P < 0.001). Scores of all domains except pain showed significant (P < 0.001) decrease with increase of the severity of CK. Group 3 had significant lower scores than group 2 in all SRS-22r domains except mental health. Satisfaction domain had significant lower scores than all other SRS-22r domains for group 1, 2, and 3. All patients of groups 2 and 3 gave the minimum answers for satisfaction domain questions. A total of 69%, 84% and 94% of group 1, 2, and 3, respectively, gave the minimum answer when asked whether their back condition affects their personal relationships. Female patients of group 1, 2, and 3 had significant lower scores for self-image domain. CONCLUSION: HRQOL is severely affected in adolescents with untreated severe CK and CKS in a developing country. LEVEL OF EVIDENCE: 3. PMID- 29462065 TI - Biomechanical Comparison of Four Different Atlantoaxial Posterior Fixation Constructs in Adults: A Finite Element Study. AB - STUDY DESIGN: Finite element analysis. OBJECTIVE: To compare the biomechanical stability imparted to the C1 and C2 vertebrae by the transarticular (TA), C1 lateral mass (LM)-C2 pedicle (PS), C1LM-C2 pars, and C1LM-C2 translaminar (TL) screw fixation techniques. SUMMARY OF BACKGROUND DATA: Cadaveric biomechanical studies of several atlantoaxial posterior fixation techniques have been performed, showing significant heterogeneity in biomechanical properties among the studies. METHODS: From computed tomography images, a nonlinear intact three dimensional C1-2 finite element model was developed and validated. Four finite element models were reconstructed from different C1-2 fixation techniques. The range of motion (ROM) and maximum von Misses stresses for the four screw techniques were compared under flexion, extension, lateral bending, and axial rotation. RESULTS: C1LM-C2PS showed the greatest decrease in ROM with flexion/extension and lateral bending. C1-2TA and C1LM-C2 pars showed less ROM reduction than the other techniques, in flexion/extension. C1LM-C2TL showed the least decrease in ROM during axial rotation. For C1-2TA, the maximum stress was in the C1-2 joint region. In the C1LM-C2PS, the C1 rod head, C2 pars screw, and C2TL screw were stressed at the C2 rod head. The maximal von Mises stress on the C1-2TA at the C1-2 joint site was the highest at flexion/extension, whereas the C1LM-C2PS had the lowest stress on the screw at flexion/extension and lateral bending. The C1LM-C2TL showed the highest stress in axial rotation and lateral bending. CONCLUSION: In this study, C1LM-C2PS fixation was the most stable technique. If surgeons have to use other fixation methods besides the C2 pedicle screw, they need to be aware that additional fixation or postoperative immobilization may be required to achieve ROM restriction. Careful observation at the maximum stress site on the screw including screw loosening, screw-bone interface disruption or screw fracture will be necessary during follow-up imaging examinations (x-ray and computed tomography scan) after atlantoaxial fixation. LEVEL OF EVIDENCE: N/A. PMID- 29462066 TI - Outcomes of Surgical Decompression in Patients With Very Severe Degenerative Cervical Myelopathy. AB - STUDY DESIGN: A prospective observational international study. OBJECTIVE: The aim of this study was to evaluate outcomes of decompressive surgery in patients with very severe degenerative cervical myelopathy (DCM). SUMMARY OF BACKGROUND DATA: Although decompressive surgery has been evidenced as a safe and effective approach for patients with myelopathic deficiencies, studies have suggested residual disability following treatment in patients with more severe disease presentation. METHODS: Postoperative outcomes of 60 patients with very severe DCM (modified Japanese Orthopaedic Association [mJOA] score <=8) were compared to outcomes of 188 patients with severe DCM (mJOA 9-11). Postimputation follow-up rate was 93.1%. Unadjusted and adjusted analyses were performed using two-way repeated measures of covariance. RESULTS: The two cohorts were similar in demographics, length of duration of myelopathy symptoms, source of stenosis, and surgical approaches used to decompress the spine. The very severe and severe cohorts differed in preoperative Nurick grades (4.97 vs. 3.91, respectively, P < 0.0001) and Neck Disability Index scores (45.20 vs. 56.21, respectively, P = 0.0006). There were no differences in Short Form 36 (SF-36v2) physical (PCS) and mental (MCS) component summary scores. Both cohorts improved in mJOA, Nurick, Neck Disability Index, and SF-36v2 PCS and MCS scores. Despite the substantial postoperative improvements, patients in both cohorts had considerable residual symptoms. Two-thirds of the patients in the very severe cohort had severe (mJOA <=11) or moderate (mJOA <= 14) myelopathy symptoms at 24 months follow-up. Longer duration of disease was associated with poorer treatment response. CONCLUSION: Decompressive surgery is effective in patients with very severe DCM; however, patients have significant residual symptoms and disability. The very severe subgroup (mJOA <=8) of patients with DCM represents a distinct group of patients and their different clinical trajectory is important for clinicians and patients to recognize. Duration of symptoms negatively affects chances for recovery. Whenever possible, patients with DCM should be treated before developing very severe symptomatology. LEVEL OF EVIDENCE: 2. PMID- 29462067 TI - Postoperative Walking Ability of Non-ambulatory Cervical Myelopathy Patients. AB - STUDY DESIGN: A retrospective analysis. OBJECTIVE: The aim of this study was to clarify the postoperative improvement of walking ability and prognostic factors in nonambulatory patients with cervical myelopathy. SUMMARY OF BACKGROUND DATA: Many researchers have reported the surgical outcome in compressive cervical myelopathy. However, regarding severe gait disturbance,, it has not been clarified yet how much improvement can be expected. METHODS: One hundred thirty one nonambulatory patients with cervical myelopathy were treated surgically and followed for an average of 3 years. Walking ability was graded according to the lower-extremity function subscore (L/E subscore) in Japanese Orthopedic Association score. We divided patients based on preoperative L/E subscores: group A, L/E subscore of 1 point (71 patients); and group B, 0 or 0.5 point (60 patients). The postoperative walking ability was graded by L/E subscore: excellent, >=2 points; good, 1.5 points; fair, 1 point; and poor, 0.5 or 0 points. We compared preoperative and postoperative scores. The cutoff value of disease duration providing excellent improvement was investigated. RESULTS: Overall, 50 patients were graded as excellent (38.2%), and 21 patients were graded as good (16.0%). In group B, 17 patients (28.3%) were graded as excellent. Seventeen patients who were graded as excellent had shorter durations of myelopathic symptoms and/or gait disturbance (7.9 and 3.8 months respectively) than the others (29.5 and 8.9 months, respectively) (P < 0.05). Receiver operating characteristic curve showed that the optimal cutoff values of the duration of myelopathic symptoms and gait disturbance providing excellent improvement were 3 and 2 months, respectively. CONCLUSION: Even if the patients were nonambulatory, 28.3% of them became able to walk without support after operation. If a patient becomes nonambulatory within 3 months from the onset of myelopathy or 2 months from the onset of gait disturbance, surgical treatment should be performed immediately to raise the possibility to improve stable gait.

PMID- 29462068 TI - Risk Factors of Impaired Pulmonary Function in Arthrogryposis Multiplex Congenital Patients With Concomitant Scoliosis: A Comparison With Adolescent Idiopathic Scoliosis. AB - STUDY DESIGN: A retrospective study. OBJECTIVE: To investigate the severity of pulmonary function impairment for arthrogryposis multiplex congenital (AMC) patients with concomitant scoliosis and to determine risk factors associated with the impaired pulmonary function in these patients. SUMMARY OF BACKGROUND DATA: AMC patients are generally believed to have impaired pulmonary function. However, the severity of respiratory morbidity and the associated risk factors have not been reported. METHODS: The pulmonary function tests data including the percentage predicted values of forced vital capacity (%FVC), forced expiratory volume in 1 second (%FEV1), and the ratio of FEV1 to FVC (%FEV1/FVC) were reviewed and compared for 48 AMC patients with secondary scoliosis and 48 patients with adolescent idiopathic scoliosis. The radiographic parameters of coronal and sagittal plane deformities and body mass index (BMI) were measured and correlated with impaired pulmonary function in these AMC patients. RESULTS: AMC patients with concomitant scoliosis had significant lower mean %FVC, %FEV1, and %FEV1/FVC than adolescent idiopathic scoliosis patients (48.8 vs. 70.3 for %FVC, P < 0.001; 45.3 vs. 69.7 for %FEV1, P < 0.001; 92.1 vs. 96.9 for %FEV1/FVC, P < 0.05, respectively). Seventy percent of AMC patients had severe pulmonary function impairment. A positive correlation was found between BMI and %FVC and %FEV1 (P < 0.01) and between hypokyphosis and %FVC and %FEV1 (P < 0.05). A negative correlation was found between coronal angle and pulmonary function (P < 0.05). Multiple regression analysis showed that all of the three variables were independent predictors associated with a reduced pulmonary function. With a combination of these variables, the multiple regression model could account for 38.7% of the variance in %FVC and 41.5% in %FEV1. CONCLUSION: There exists severe impairment of pulmonary function in AMC patients with concomitant scoliosis. The scoliotic curve, hypokyphosis, and BMI were independent risk factors associated with the pulmonary dysfunction in these patients. As the majority of the variability of impaired pulmonary function tests are still poorly understood, more risk factors await to be uncovered in future studies. LEVEL OF EVIDENCE: 4. PMID- 29462069 TI - The Association Between Body Mass Index and the Prevalence, Severity, and Frequency of Low Back Pain: Data From the Osteoarthritis Initiative. AB - STUDY DESIGN: Cross-sectional study. OBJECTIVE: To determine whether there is an association between body mass index (BMI) and the prevalence, severity, and frequency of low back pain and identify other potential patient risk factors for the development of low back pain. SUMMARY OF BACKGROUND DATA: Many studies have implicated that a high BMI is a risk factor for low back pain. However, few studies have examined the association between increased BMI and the prevalence, severity, and frequency of low back pain. METHODS: Data from the Osteoarthritis Initiative, a multicenter, prospective study of knee osteoarthritis, were used to conduct this study, which included 4796 patients. BMI was categorized according to the World Health Organization classification and the prevalence, severity, and frequency of low back pain were assessed. Logistic regression was performed to identify additional patient risk factors associated with low back pain. RESULTS: The prevalence of low back pain was found to be significantly higher in patients with an elevated BMI compared to those with normal or underweight BMI and demonstrated a stepwise increase with each BMI category. Approximately 47.4% of patients with normal or underweight BMI complained of low back pain compared with 72.8% of morbidly obese patients (P < 0.0001). No association was seen between BMI and the frequency or severity of low back pain episodes. Osteoarthritis of the back and depression were patient variables found to be associated with all three measures (prevalence, severity, and frequency) of low back pain. CONCLUSION: Elevated BMI is strongly associated with an increased prevalence of low back pain. Depression and osteoarthritis of the back are associated with the prevalence, severity, and frequency of low back pain. LEVEL OF EVIDENCE: 3. PMID- 29462070 TI - Bisphosphonate and Teriparatide Use in Thoracolumbar Spinal Fusion: A Systematic Review and Meta-analysis of Comparative Studies. AB - STUDY DESIGN: Systematic review and meta-analysis. OBJECTIVE: To compare the efficacy of the use of either bisphosphonates or teriparatide on radiographic and functional outcomes of patients that had thoracolumbar spinal fusion. SUMMARY OF BACKGROUND DATA: Controversy exists as to whether bisphosphonates interfere with successful spinal arthrodesis. An alternative osteoporosis medication is teriparatide, a synthetic parathyroid hormone that has an anabolic effect on osteoblast function. To date, there is limited comparative data on the influence of bisphosphonates or teriparatide on spinal fusion. METHODS: A systematic search of medical reference databases was conducted for comparative studies on bisphosphonate or teriparatide use after thoracolumbar spinal fusion. Meta analysis was performed using the random-effects model for heterogeneity. Radiographic outcomes assessed include fusion rates, risk of screw loosening, cage subsidence, and vertebral fracture. RESULTS: No statistically significant differences were noted between bisphosphonates and control groups regarding fusion rate and risk of screw loosening (fusion: odds ratio [OR] = 2.2, 95% confidence interval [CI]: 0.87-5.56, P = 0.09; loosening: OR = 0.45, 95% CI: 0.14 1.48, P = 0.19). Teriparatide use was associated with higher fusion rates than bisphosphonates (OR = 2.3, 95% CI: 1.55-3.42, P < 0.0001). However, no statistically significant difference was noted between teriparatide and bisphosphonates regarding risk of screw loosening (OR = 0.37, 95% CI: 0.12-1.18, P = 0.09). Lastly, bisphosphonate use was associated with decreased odds of cage subsidence and vertebral fractures compared to controls (subsidence: OR = 0.29, 95% CI 0.11-0.75, P = 0.01; fracture: OR = 0.18, 95% CI 0.07-0.48, P = 0.0007). CONCLUSION: Bisphosphonates do not appear to impair successful spinal fusion compared to controls although teriparatide use is associated with higher fusion rates than bisphosphonates. In addition, bisphosphonate use is associated with decreased odds of cage subsidence and vertebral fractures compared to controls that had spinal fusion. LEVEL OF EVIDENCE: 3. PMID- 29462071 TI - The Relationship Between Improvements in Myelopathy and Sagittal Realignment in Cervical Deformity Surgery Outcomes. AB - STUDY DESIGN: Retrospective review. OBJECTIVE: Determine whether alignment or myelopathy improvement drives patient outcomes after cervical deformity (CD) corrective surgery. SUMMARY OF BACKGROUND DATA: CD correction involves radiographic malalignment correction and procedures to improve motor function and pain. It is unknown whether alignment or myelopathy improvement drives patient outcomes. METHODS: Inclusion: Patients with CD with baseline/1-year radiographic and outcome scores. Cervical alignment improvement was defined by improvement in Ames CD modifiers. modified Japanese Orthopaedic Association (mJOA) improvement was defined as mild [15-17], moderate [12-14], severe [<12]. Patient groups included those who only improved in alignment, those who only improved in mJOA, those who improved in both, and those who did not improve. Changes in quality-of life scores (neck disability index [NDI], EuroQuol-5 dimensions [EQ-5D], mJOA) were evaluated between groups. RESULTS: A total of 70 patients (62 yr, 51% F) were included. Overall preoperative mJOA score was 13.04 +/- 2.35. At baseline, 21 (30%) patients had mild myelopathy, 33 (47%) moderate, and 16 (23%) severe. Out of 70 patients 30 (44%) improved in mJOA and 13 (18.6%) met 1-year mJOA minimal clinically important difference. Distribution of improvement groups: 16/70 (23%) alignment-only improvement, 13 (19%) myelopathy-only improvement, 18 (26%) alignment and myelopathy improvement, and 23 (33%) no improvement. EQ-5D improved in 11 of 16 (69%) alignment-only patients, 11 of 18 (61%) myelopathy/alignment improvement, 13 of 13 (100%) myelopathy-only, and 10 of 23 (44%) no myelopathy/alignment improvement. There were no differences in decompression, baseline alignment, mJOA, EQ-5D, or NDI between groups. Patients who improved only in myelopathy showed significant differences in baseline-1Y EQ 5D (baseline: 0.74, 1 yr:0.83, P < 0.001). One-year C2-S1 sagittal vertical axis (SVA; mJOA r = -0.424, P = 0.002; EQ-5D r = -0.261, P = 0.050; NDI r = 0.321, P = 0.015) and C7-S1 SVA (mJOA r = -0.494, P < 0.001; EQ-5D r = -0.284, P = 0.031; NDI r = 0.334, P = 0.010) were correlated with improvement in health-related qualities of life. CONCLUSION: After CD-corrective surgery, improvements in myelopathy symptoms and functional score were associated with superior 1-year patient-reported outcomes. Although there were no relationships between cervical specific sagittal parameters and patient outcomes, global parameters of C2-S1 SVA and C7-S1 SVA showed significant correlations with overall 1-year mJOA, EQ-5D, and NDI. These results highlight myelopathy improvement as a key driver of patient-reported outcomes, and confirm the importance of sagittal alignment in patients with CD. LEVEL OF EVIDENCE: 3. PMID- 29462072 TI - Anterior to Dorsal Root Entry Zone Myelotomy (ADREZotomy): A New Surgical Approach for the Treatment of Ventrolateral Deep Intramedullary Spinal Cord Cavernous Malformations. AB - STUDY DESIGN: A retrospective review of prospectively collected data. OBJECTIVE: To confirm the feasibility of using anterior to dorsal root entry zone myelotomy (ADREZotomy), a new surgical approach, for the treatment of ventrolateral deep intramedullary spinal cord cavernous malformation (ISCCMs). SUMMARY OF BACKGROUND DATA: Surgical removal of ventrolateral deep ISCCMs is highly risky and remains problematic. METHODS: The authors performed a retrospective study exploring the surgical removal of ventrolateral intrinsic ISCCMs using ADREZotomy in 10 patients. The Frankel grading system was used to evaluate the patients' neurological function at the preoperative, postoperative and follow-up stages. American Spinal Injury Association Scale scores at the preoperative and postoperative were also obtained. The patient characteristics and surgical outcomes were analyzed. The indication, operative steps, complications, and anatomical basis of the myelotomies were described and discussed. RESULTS: In total, nine (90%) patients presented with mild symptoms before surgery. Gross total resections were performed in all 10 patients. Immediately after surgery, the neurological function of eight (80.0%) patients remained the same. One patient improved and one (10%) patient worsened. There were no other immediate or delayed complications related to the surgical procedure. No decrease of total American Spinal Injury Association sensory scores was observed. The follow-up neurological function evaluation showed that two (20%) patients improved from a Frankel grade of D to E and eight (80.0%) patients were stable. No recurrences or other additional neurological deterioration was observed. CONCLUSION: Surgical removal of ventrolateral deep ISCCMs can be feasible using proper surgical techniques. ADREZotomy is a minimally invasive technique for the removal of cervical and thoracic ventrolateral deep ISCCMs, without disrupting the important spinal cord tracts or the need to broadly expose bone.

PMID- 29462074 TI - Radial Shaft Convergence in Distal Radius Fractures: Diagnosis and Treatment. AB - Radial shaft convergence in distal radius fractures is often misdiagnosed. This common deformation is often associated with a radial translation of the distal fragment. This parameter has to be corrected because of the increased risk of distal radioulnar joint instability due to detensioning of the distal interosseous membrane if there is an associated triangular fibrocartilage complex lesion. A new radiologic sign for diagnosis of proximal radius convergence during distal radius fracture is presented as well as technical tips for correction of this deformity. PMID- 29462075 TI - Hospital Characteristics Associated With Postdischarge Hospital Readmission, Observation, and Emergency Department Utilization. AB - BACKGROUND: Whether types of hospitals with high readmission rates also have high overall postdischarge acute care utilization (including emergency department and observation care) is unknown. DESIGN: Cross-sectional analysis. SUBJECTS: Nonfederal United States acute care hospitals. MEASURES: Using methodology established by the Centers for Medicare & Medicaid Services, we calculated each hospital's "excess days in acute care" for fee-for-service (FFS) Medicare beneficiaries aged over 65 years discharged after hospitalization for acute myocardial infarction, heart failure (HF), or pneumonia, representing the mean difference between predicted and expected total days of acute care utilization in the 30 days following hospital discharge, per 100 discharges. We assessed the multivariable association of 8 hospital characteristics with excess days in acute care and the proportion of hospitals with each characteristic that were statistical outliers (95% credible interval estimate does not include 0). RESULTS: We included 2184 hospitals for acute myocardial infarction [228 (10.4%) better than expected, 549 (25.1%) worse than expected], 3720 hospitals for HF [484 (13.0%) better and 840 (22.6%) worse], and 4195 hospitals for pneumonia [673 (16.0%) better, 1005 (24.0%) worse]. Results for all conditions were similar. Worse than expected outliers for pneumonia included: 18.8% of safety net hospitals versus 26.1% of nonsafety net hospitals; 16.7% of public hospitals versus 33.1% of for-profit hospitals; 19.5% of nonteaching hospitals versus 52.2% of major teaching hospitals; 7.9% of rural hospitals versus 42.1% of large urban hospitals; 5.9% of hospitals with 24-<50 beds versus 58% of hospitals with >500 beds; and 29.0% of hospitals with nurse-to-bed ratios >1.0-1.5 versus 21.7% of hospitals with ratios >2.0. CONCLUSIONS: Including emergency department and observation stays in measures of postdischarge utilization produces similar results as measuring only readmissions in that major teaching, urban and for profit hospitals still perform disproportionately poorly versus nonteaching or public hospitals. However, it enables identification of more outliers and a more granular assessment of the association of hospital factors and outcomes. PMID- 29462076 TI - Medicare Advantage Penetration and Hospital Costs Before and After the Affordable Care Act. AB - BACKGROUND: Research has suggested that growth in the Medicare Advantage (MA) program indirectly benefits the entire 65+-year-old population by reducing overall expenditures and creating spillover effects of patient care practices. Medicare programs and innovations initiated by the Affordable Care Act (ACA) have encouraged practices to adopt models applying to all patient populations, which may influence the continued benefits of MA program growth. OBJECTIVE: This study investigated the relationship between MA program growth and inpatient hospital costs and utilization before and after the ACA. METHODS: Primary data sources were 2005-2014 Health Care Cost and Utilization Project hospital data and 2004 2013 Centers for Medicare & Medicaid Services enrollment data. County-year-level regression analysis with fixed effects examined the relationship between Medicare managed care penetration and hospital cost per enrollee. We decomposed results into changes in utilization, severity, and severity-adjusted inpatient resource use. Analyses were stratified by whether the admission was urgent or nonurgent. PRINCIPAL FINDINGS: A 10% increase in MA penetration was associated with a 3 percentage point decrease in inpatient cost per Medicare enrollee before the ACA. This effect was more prominent in nonurgent admissions and diminished after the ACA. CONCLUSIONS: Results suggest that MA enrollment growth is associated with diminished spillover reductions in hospital admission costs after the ACA. We did not observe a strong relationship between MA enrollment and inpatient days per enrollee. Future research should examine whether spillover effects still are observed in outpatient settings. PMID- 29462077 TI - Maryland Multipayor Patient-centered Medical Home Program: A 4-Year Quasiexperimental Evaluation of Quality, Utilization, Patient Satisfaction, and Provider Perceptions. AB - OBJECTIVE: To evaluate impact of the Maryland Multipayor Patient-centered Medical Home Program (MMPP) on: (1) quality, utilization, and costs of care; (2) beneficiaries' experiences and satisfaction with care; and (3) perceptions of providers. DESIGN: 4-year quasiexperimental design with a difference-in differences analytic approach to compare changes in outcomes between MMPP practices and propensity score-matched comparisons; pre-post design for patient reported outcomes among MMPP beneficiaries. SUBJECTS: Beneficiaries (Medicaid insured and privately insured) and providers in 52 MMPP practices and 104 matched comparisons in Maryland. INTERVENTION: Participating practices received unconditional financial support and coaching to facilitate functioning as medical homes, membership in a learning collaborative to promote education and dissemination of best practices, and performance-based payments. MEASURES: Sixteen quality, 20 utilization, and 13 cost measures from administrative data; patient-reported outcomes on care delivery, trust in provider, access to care, and chronic illness management; and provider perceptions of team operation, team culture, satisfaction with care provided, and patient-centered medical home transformation. RESULTS: The MMPP had mixed impact on site-level quality and utilization measures. Participation was significantly associated with lower inpatient and outpatient payments in the first year among privately insured beneficiaries, and for the entire duration among Medicaid beneficiaries. There was indication that MMPP practices shifted responsibility for certain administrative tasks from clinicians to medical assistants or care managers. The program had limited effect on measures of patient satisfaction (although response rates were low) and on provider perceptions. CONCLUSIONS: The MMPP demonstrated mixed results of its impact and indicated differential program effects for privately insured and Medicaid beneficiaries. PMID- 29462078 TI - The Impact of a Health Information Technology-Focused Patient-centered Medical Neighborhood Program Among Medicare Beneficiaries in Primary Care Practices: The Effect on Patient Outcomes and Spending. AB - BACKGROUND: The Center for Medicare & Medicaid Innovation (CMMI) tests new models of paying for or delivering health care services and expands models that improve health outcomes while lowering medical spending. CMMI gave TransforMED, a national learning and dissemination contractor, a 3-year Health Care Innovation Award (HCIA) to integrate health information technology systems into physician practices. This paper estimates impacts of TransforMED's HCIA-funded program on patient outcomes and Medicare parts A and B spending. RESEARCH DESIGN: We compared outcomes for Medicare fee-for-service (FFS) beneficiaries served by 87 treatment practices to outcomes for Medicare FFS beneficiaries served by 286 matched comparison practices, adjusting for differences in outcomes between the 2 groups during a 1-year baseline period. We estimated impacts in 3 evaluation outcome domains: quality-of-care processes, service use, and spending. RESULTS: We estimated the program led to a 7.1% reduction in inpatient admissions and a 5.7% decrease in the outpatient emergency department visits. However, there was no evidence of statistically significant effects in outcomes in either the quality-of-care processes or spending domains. CONCLUSIONS: These results indicate that TransforMED's program reduced service use for Medicare FFS beneficiaries, but also show that the program did not have statistically significant favorable impacts in the quality-of-care processes or spending domains. These results suggest that providing practices with population health management and cost-reporting software-along with technical assistance for how to use them-can complement practices' own patient-centered medical home transformation efforts and add meaningfully to their impacts on service use. PMID- 29462079 TI - Care Experiences Among Medicare Beneficiaries With and Without a Personal Physician. AB - BACKGROUND: Having a "personal" physician is a critical element to care continuity. Little is known about which older adults are more likely to lack personal physicians and if their care experiences differ from those with a personal physician. OBJECTIVE: The objective of this study was to describe care experiences and characteristics associated with not having a personal physician. RESEARCH DESIGN: We compare rates of lacking a personal physician across subgroups. Using doubly robust propensity-score-weighted regression, we compare patient experience among beneficiaries with and without a personal physician. SUBJECTS: A total of 272,463 nationally representative beneficiaries age 65+ responding to the 2012 Medicare CAHPS survey. MEASURES: Beneficiary characteristics, having a personal physician, 4 patient experience measures. RESULTS: Five percent of respondents reported no personal physician. Lacking a personal physician was more common for men, racial/ethnic minorities (eg, 16% of American Indian/Alaska Natives), and the younger and less educated. Those without a personal physician reported substantially poorer experiences on 4 measures (P<0.001); these differences are larger than those observed by key demographic characteristics. Beneficiaries without a personal physician were more than 3 times as likely to have not seen any health care provider in the last 6 months. CONCLUSIONS: Even with the access provided by Medicare, a small but nontrivial proportion of seniors report having no personal physician. Those without a personal physician report substantially worse patient experiences and lacking a personal physician is more common for some vulnerable groups. This may underlie some previously observed disparities. Efforts should be made to encourage and help seniors without personal physicians to select one. PMID- 29462080 TI - Characterizing injury severity in nonaccidental trauma: Does Injury Severity Score miss the mark? AB - BACKGROUND: Children suffering nonaccidental trauma (NAT) are at high risk of death. It is unclear whether markers of injury severity for trauma center/system benchmarking such as Injury Severity Score (ISS) adequately characterize this. Our objective was to evaluate mortality prediction of ISS in children with NAT compared with accidental trauma (AT). METHODS: Pediatric patients younger than 16 years from the Pennsylvania state trauma registry 2000 to 2013 were included. Logistic regression predicted mortality from ISS for NAT and AT patients. Multilevel logistic regression determined the association between mortality and ISS while adjusting for age, vital signs, and injury pattern in NAT and AT patients. Similar models were performed for head Abbreviated Injury Scale (AIS). Sensitivity analysis examined impaired functional independence at discharge as an alternate outcome. RESULTS: Fifty thousand five hundred seventy-nine patients were included with 1,866 (3.7%) NAT patients. Nonaccidental trauma patients had a similar rate of mortality at an ISS of 13 as an ISS of 25 for AT patients. Nonaccidental trauma patients also have higher mortality for a given head AIS level (range, 1.2-fold to 5.9-fold higher). Injury Severity Score was a significantly greater predictor of mortality in AT patients (adjusted odds rations [AOR], 1.14; 95% confidence interval [CI], 1.13-1.15; p < 0.01) than NAT patients (AOR, 1.09; 95% CI, 1.07-1.12; p < 0.01) per 1-point ISS increase, while head injury was a significantly greater predictor of mortality in NAT patients (AOR, 3.48; 95% CI, 1.54-8.32; p < 0.01) than AT patients (AOR, 1.21; 95% CI, 0.95-1.45; p = 0.12). Nonaccidental trauma patients had a higher rate of impaired functional independence at any given ISS or head AIS level than AT patients. CONCLUSION: Nonaccidental trauma patients have higher mortality and impaired function at a given ISS/head AIS than AT patients. Conventional ISS thresholds may underestimate risk and head injury is a more important predictor of mortality in the NAT population. These findings should be considered in system performance improvement and benchmarking efforts that rely on ISS for injury characterization. LEVEL OF EVIDENCE: Epidemiologic study, level III. PMID- 29462081 TI - The opioid epidemic in acute care surgery-Characteristics of overprescribing following laparoscopic cholecystectomy. AB - BACKGROUND: Postoperative prescribing following acute care surgery must be optimized to limit excess opioids in circulation as misuse and diversion are frequently preceded by a prescription for acute pain. This study aimed to identify patient characteristics associated with higher opioid prescribing following laparoscopic cholecystectomy (LC). METHODS: Among patients aged 18 years or older who underwent LC at a single institution in 2014 to 2016, opioids prescribed at discharge were converted to oral morphine equivalents (OME) and compared with developing state guidelines (maximum, 200 OME). Preoperative opioid use was defined as any opioid prescription 1 month to 3 months before LC or a prescription unrelated to gallbladder disease less than 1 month before LC. Univariate and multivariable methods determined characteristics associated with top quartile opioid prescriptions among opioid-naive patients. RESULTS: Of 1,606 LC patients, 34% had emergent procedures, and 14% were preoperative opioid users. Nonemergent LC patients were more likely to use opioids preoperatively (16% vs. 11%, p = 0.006), but median OME did not differ by preoperative opioid use (225 vs. 219, p = 0.40). Among 1,376 opioid-naive patients, 96% received opioids at discharge. Median OME was 225 (interquartile range, 150-300), and 52% were prescribed greater than 200 OME. Top quartile prescriptions (>=300 OME) were associated with gallstone pancreatitis diagnosis, younger age, higher pain scores, and longer length of stay (all p < 0.05). While median OME did not differ by emergent status (median, 225; interquartile range, 150-300 for both, p = 0.15), emergent had more top quartile prescriptions (32% vs. 25%, p = 0.005). After adjusting for diagnosis, age, and sex, emergent status showed evidence of being associated with top quartile prescription (odds ratio, 1.3; 95% confidence interval, 1.0-1.8). Thirty-day refill rate was 5%. CONCLUSION: Over half of opioid-naive patients undergoing LC were prescribed opioids exceeding draft state guidelines. Variation in prescribing patterns was not fully explained by patient factors. Acute care surgeons have an opportunity to optimize prescribing practices with the ultimate goal of reducing opioid misuse.

AB - Intercostal artery injury can cause large hemothoraces. While many patients with intercostal artery injury present hemodynamically unstable and require emergent thoracotomy for hemostasis, some tamponade spontaneously. They may rebleed later, however, and cause recurrent hemothorax or retained hemothorax. Video-assisted thoracic surgery (VATS) is an effective way to evacuate retained hemothorax. However, assessing and ligating intercostal artery injury during VATS can be difficult, and often, open thoracotomy is pursued. Even with open surgery, ligation of the intercostal artery can be a challenge. We present a minimally invasive method of definitive intercostal artery ligation during VATS or open thoracotomy. PMID- 29462083 TI - Tourniquet usage in prehospital care and resuscitation of pediatric trauma patients-Pediatric Trauma Society position statement. AB - BACKGROUND: Recent mass casualty events in the United States have highlighted the need for public preparedness to prevent death from uncontrolled hemorrhage. The Pediatric Trauma Society (PTS) reviewed the literature regarding pediatric tourniquet usage with the aim to provide recommendations about the utility of this adjunct for hemorrhage control in children. METHODS: Search terms "pediatric" and "tourniquet" were used to query the US National Library of Medicine National Institutes of Health for pertinent literature. Exclusion criteria include not involving children, not involving the use of an extremity tourniquet, primary outcomes not related to hemorrhage control, tourniquet use to prevent snake envenomation, single case reports, and only foreign language formats available. Bibliographies of remaining studies reviewed to identify additional pertinent research. Four physician members of the PTS Guidelines Committee reviewed identified studies. RESULTS: One hundred thirty-four studies were identified. One hundred twenty-three studies were excluded. Seven additional studies were identified through bibliography review. Eighteen pertinent studies were reviewed. Seven articles evaluated physiologic response to tourniquet use in operating room settings. Six articles were generated from combat experience in conflicts in Afghanistan and Iraq. Four articles discussed technical details of tourniquet usage. One article evaluated the use of tourniquets during the Boston Marathon bombing in 2015. CONCLUSION: Despite limited data of limited quality regarding their use, the PTS supports the usage of tourniquets in the prehospital setting and during the resuscitation of children suffering from exsanguinating hemorrhage from severe extremity trauma. Expedited, definitive care must be sought, and tourniquet pressure and time should be limited to the least amount possible. The Society supports the ACS "Stop the Bleed" campaign and encourages further investigation of tourniquet use in children. LEVEL OF EVIDENCE: Guidelines/algorithm study, level IIIa. PMID- 29462084 TI - Physician training in critical care in the United States: Update 2018. AB - Critical care fellowship training in the United States differs based on specific specialty and includes medicine, surgery, anesthesiology, pediatrics, emergency medicine, and neurocritical care training pathways. We provide an update regarding the number and growth of US critical care fellowship training programs, on-duty residents and certified diplomates, and review the different critical care physician training pathways available to residents interested in pursuing a fellowship in critical care. Data were obtained from the Accreditation Council for Graduate Medical Education and specialty boards (American Board of Internal Medicine, American Board of Surgery, American Board of Anesthesiology, American Board of Pediatrics American Board of Emergency Medicine) and the United Council for Neurologic Subspecialties for the last 16 years (2001-2017). The number of critical care fellowship training programs has increased 22.6%, with a 49.4% increase in the number of on-duty residents annually, over the last 16 years. This is in contrast to the period of 1995 to 2000 when the number of physicians enrolled in critical care fellowship programs had decreased or remained unchanged. Although more than 80% of intensivists in the US train in internal medicine critical care Accreditation Council for Graduate Medical Education approved fellowships, there has been a significant increase in the number of residents from surgery, anesthesiology, pediatrics, emergency medicine, and other specialties who complete specialty fellowship training and certification in critical care. Matriculation in neurocritical care fellowships is rapidly rising with 60 programs and over 1,200 neurocritical care diplomates. Critical care is now an increasingly popular fellowship in all specialties. This rapid growth of all critical care specialties highlights the magnitude of the heterogeneity that will exist between intensivists in the future. PMID- 29462085 TI - Nonocclusive mesenteric ischemia in patients with methamphetamine use. AB - BACKGROUND: Data suggest that methamphetamine may increase the risk of nonocclusive mesenteric ischemia (NOMI). We describe patterns of presentation and outcomes of patients with methamphetamine use who present with NOMI to a single institution. METHODS: This is an observational study of patients from January 2015 to September 2017 with methamphetamine use who presented with NOMI at an academic medical center in Northern California. We summarize patient comorbidities, clinical presentation, operative findings, pathologic findings, hospital course, and survival. RESULTS: Ten patients with methamphetamine use and severe NOMI were identified. One patient was readmitted with a perforated duodenal ulcer, for a total of 11 encounters. Most presented with acute (n = 3) or acute-on-chronic (n = 4) abdominal pain. Distribution of ischemia ranged from perforated duodenal ulcer (n = 3), ischemia of the distal ileum (n = 1), ischemia of entire small bowel (n = 2), and patchy necrosis of entire small bowel and colon (n = 5). Six patients died, three within 1 week of admission and three between 3 months and 8 months. CONCLUSION: Methamphetamine use may be associated with significant microvascular compromise, increasing the risk of mesenteric ischemia. Providers in areas with high prevalence of methamphetamine use should have a high index of suspicion for intestinal ischemia in this patient population. Patients with methamphetamine use admitted for trauma or other pathology may be at particular risk of ischemia and septic shock, especially in the setting of dehydration. Use of vasoconstrictors in this patient population may also exacerbate intestinal ischemia. LEVEL OF EVIDENCE: Therapeutic Case series study, level V. PMID- 29462086 TI - Emergency sternal intraosseous access for warm fresh whole blood transfusion in damage control resuscitation. AB - BACKGROUND: Intraosseous (IO) vascular access is increasingly used as an emergency tool for achieving access to the systemic circulation in critically ill patients. The role of IO transfusion of blood in damage control resuscitation is however questionable due to possible inadequate flow rate and hemolysis. Some experts claim that IO transfusion is contraindicated. In this study, we have challenged this statement by looking at flow rates of autologous fresh whole blood reinfusion and hemolysis using two of the commonly used Food and Drug Administration-approved and Conformite Europeenne (CE)-marked sternal needles. Additionally, the success rate of sternal access between the two devices is evaluated. METHODS: Volunteer professional military personnel, were enrolled prospectively in a nonrandomized observational study design. We collected 450 mL of autologous whole blood from each participant. Participants were divided into the following three groups of 10: Tactically Advanced Lifesaving IO Needle (T.A.L.O.N.) IO, FAST1 IO, and intravenous group. The reinfusion was done by gravity only. Blood sampling was performed before blood collection and 30 minutes after reinfusion. Investigation of hemolysis was performed by measurements of haptoglobin and lactate dehydrogenase. Success rate was evaluated by correct aspiration of bone marrow. RESULTS: Median reinfusion rate was 46.2 mL/min in the FAST1 group, 32.4 mL/min in the T.A.L.O.N. group, and 74.1 mL/min in the intravenous group. Blood samples from all participants were within normal ranges. There was no statistically significant difference in haptoglobin and lactate dehydrogenase between the groups. In the FAST1 group, 1 (9%) of 11 procedures failed. In the T.A.L.O.N. group, 4 (29%) of 14 procedures failed. CONCLUSION: Although preferable, achieving peripheral venous access in the bleeding patient is a major problem. Our findings suggest that fresh whole-blood transfusion through the IO route is safe, reliable, and provide sufficient flow for resuscitation.

AB - BACKGROUND: Determine the prognostic impact of magnetic resonance imaging (MRI) defined diffuse axonal injury (DAI) after traumatic brain injury (TBI) on functional outcomes, quality of life, and 3-year mortality. METHODS: This retrospective single center cohort included adult trauma patients (age > 17 years) admitted from 2006 to 2012 with TBI. Inclusion criteria were positive head computed tomography with brain MRI within 2 weeks of admission. Exclusion criteria included penetrating TBI or prior neurologic condition. Separate ordinal logistic models assessed DAI's prognostic value for the following scores: (1) hospital-discharge Functional Independence Measure, (2) long-term Glasgow Outcome Scale-Extended, and (3) long-term Quality of Life after Brain Injury-Overall Scale. Cox proportional hazards modeling assessed DAI's prognostic value for 3 year survival. Covariates included age, sex, race, insurance status, Injury Severity Score, admission Glasgow Coma Scale Score, Marshall Head computed tomography Class, clinical DAI on MRI (Y/N), research-level anatomic DAI Grades I III (I, cortical; II, corpus callosum; III, brainstem), ventilator days, time to follow commands, and time to long-term follow-up (for logistic models). RESULTS: Eligibility criteria was met by 311 patients, who had a median age of 40 years (interquartile range [IQR], 23-57 years), Injury Severity Score of 29 (IQR, 22 38), intensive care unit stay of 6 days (IQR, 2-11 days), and follow-up of 5 years (IQR, 3-6 years). Clinical DAI was present on 47% of MRIs. Among 300 readable MRIs, 56% of MRIs had anatomic DAI (25% Grade I, 18% Grade II, 13% Grade III). On regression, only clinical (not anatomic) DAI was predictive of a lower Functional Independence Measure score (odds ratio, 2.5; 95% confidence interval, 1.28-4.76], p = 0.007). Neither clinical nor anatomic DAI were related to survival, Glasgow Outcome Scale-Extended, or Quality of Life after Brain Injury Overall Scale scores. CONCLUSION: In this longitudinal cohort, clinical evidence of DAI on MRI may only be useful for predicting short-term in-hospital functional outcome. Given no association of DAI and long-term TBI outcomes, providers should be cautious in attributing DAI to future neurologic function, quality of life, and/or survival.

PMID- 29462088 TI - Vascular surgery during U.S. combat operations from 2002 to 2016: Analysis of vascular procedures performed to inform military training. AB - BACKGROUND: Vascular surgery constitutes approximately 6.5% of surgical procedures performed for combat injuries, yet general surgeons are increasingly unfamiliar with vascular surgery. This study examines the frequency and type of vascular surgical procedures performed during recent US Military operations from 2002 to 2016. METHODS: A retrospective analysis of the Department of Defense Trauma Registry was performed for all Role (R)2 and R3 medical treatment facilities (MTFs), from January 2002 to May 2016. A total of 106 International Classification of Diseases-9th Rev.-Clinical Modification (ICD-9-CM) procedure codes were categorized as vascular and were included in the present analysis. Procedure codes were separated by anatomic location and procedure type. Ligation as part of an amputation was excluded. Grafts were further subdivided by type: synthetic, autologous, and unknown. Procedure grouping and categorization were determined by subject matter experts. Data analysis used Stata Version 14 (College Station, TX). RESULTS: A total of 25,816 vascular surgical procedures were identified at R2 and R3 MTFs. Role 3 MTFs reported more than four times the number of procedures compared to R2 MTFs. The most common anatomic locations documented were extremity (64.96%) and not otherwise specified (28.1%). The most common procedures overall were amputation (33.36%) and fasciotomy (18.83%). The most common graft type was autologous (68.87%), and the least common was synthetic (5.69%). CONCLUSION: While amputation, fasciotomy, and ligation were the most common vascular procedures performed for combat trauma, the need for definitive repair including grafting is common at both R2 and R3 MTFs. Vascular surgery therefore remains a necessary skill set for the deployed US Military surgeon; military general surgeons need to train and sustain their vascular skills, including proficiency at amputation and fasciotomy.

AB - BACKGROUND: To evaluate the management and long-term renal function with DMSA scintigraphy in pediatric severe traumatic kidney injury grade IV and V at the trauma center of Grenoble Teaching Hospital. METHODS: This is a single-center observational retrospective study between 2004 and 2014. All children younger than 15 years and managed at the Grenoble teaching Hospital for a severe trauma kidney injury grade IV or V were included. The trauma grade was radiologically diagnosed on arrival at hospital, using the classification of the American Association for Surgery of Trauma. The management followed the algorithm in effect in the establishment. The assessment of the renal function was performed by a DMSA scintigraphy after at least 6 months from the injury. RESULTS: Twenty one children were managed for a severe renal trauma (16 IV and 5 V). The diagnosis was initially made by an ultrasonography (eight cases) or a computed tomography scan (13 cases). A child with a severe renal trauma IV underwent nephrectomy on day 6 of the trauma. Eleven children needed a therapeutic procedure (three embolizations, four double J stents, one arterial stent, one peritoneal lavage for a splenic hemoperitoneum, four pleural drainages). A DMSA scintigraphy was performed in 15 patients to assess the function of the injured kidney: 11 of 16 severe renal trauma IV with an average of 39.4%, and 17% in 4 of 5 severe renal trauma V analyzed. CONCLUSION: Among the 21 children managed for a severe kidney trauma injury IV or V, 11 required a therapeutic procedure, one of them a nephrectomy. The DMSA scintigraphy performed after at least 6 months from the trauma found an injured renal function at 39.4% in 11 of 16 severe renal trauma IV analyzed, and 17% in 4 of 5 severe renal trauma V analyzed, which confirms the currently conservative management.

AB - Histomorphologic prognostic biomarkers that can be measured using only an hematoxylin and eosin stain are very attractive because they are simple and cheap. We conceived an entirely novel biomarker of this type, the Breslow density (BD), which measures invasive melanoma cell density at the site where Breslow thickness (BT) is measured. This study assessed BD's prognostic value. In this study, BD was measured in 1329 melanoma patients. Measurement accuracy and precision was assessed using intraclass correlation coefficient (ICC). Survival was assessed with a primary end-point of melanoma-specific survival (MSS) and also overall survival and metastasis-free survival. We found that BD measurement was accurate compared with gold standard image analysis (ICC, 0.84). Precision was excellent for 3 observers with different experience (ICC, 0.93) and for an observer using only written instructions (ICC, 0.93). BD was a highly significant predictor in multivariable analysis for overall survival, MSS, and metastasis free survival (each, P<0.001) and it explained MSS better than BT, but BT and BD together had best explanatory capability. A BD cut point of >=65% was trained in 970 melanomas and validated in 359. This cut point showed promise as a novel way to upstage melanoma from T stage "a" to "b." BD was combined with BT to create a targeted burden score. This was a validated as an adjunct to American Joint Committee on Cancer stage. In summary, BD can be measured accurately and precisely. It demonstrated independent prognostic value and explained MSS better than BT alone. Notably, we demonstrated ways that BD could be used with American Joint Committee on Cancer version 8 staging. PMID- 29462091 TI - Distinct Genomic Copy Number Alterations Distinguish Mucinous Tubular and Spindle Cell Carcinoma of the Kidney From Papillary Renal Cell Carcinoma With Overlapping Histologic Features. AB - Mucinous tubular and spindle cell carcinoma (MTSCC) of the kidney is a rare type of renal cell carcinoma that frequently exhibits histologic and immunophenotypic features overlapping with type 1 papillary renal cell carcinoma (PRCC). To clarify molecular attributes that can be used for this difficult differential diagnosis, we sought to delineate the genome-wide copy number alterations in tumors displaying classic histologic features of MTSCC in comparison to the solid variant of type 1 PRCC and indeterminate cases with overlapping histologic features. The study included 11 histologically typical MTSCC, 9 tumors with overlapping features between MTSCC and PRCC, and 6 cases of solid variant of type 1 PRCC. DNA samples extracted from macrodissected or microdissected tumor areas were analyzed for genome-wide copy number alterations using an SNP-array platform suitable for clinical archival material. All cases in the MTSCC group exhibited multiple chromosomal losses, most frequently involving chromosomes 1, 4, 6, 8, 9, 13, 14, 15, and 22, while lacking trisomy 7 or 17. In contrast, cases with overlapping morphologic features of MTSCC and PRCC predominantly showed multiple chromosomal gains, most frequently involving chromosomes 7, 16, 17, and 20, similar to the chromosomal alteration pattern that was seen in the solid variant of type 1 PRCC cases. Morphologic comparison of these molecularly characterized tumors identified histologic features that help to distinguish MTSCC from PRCC, but immunohistochemical profiles of these tumors remained overlapping, including a marker for Hippo-Yes-associated protein signaling. Characteristic patterns of genome-wide copy number alterations strongly support MTSCC and PRCC as distinct entities despite their immunohistochemical and certain morphologic overlap, and help define histologic features useful for the classification of questionable cases. PMID- 29462092 TI - Significance of T1a and T1b Carcinoma Arising in Mucinous Cystic Neoplasm of Pancreas. AB - Mucinous cystic neoplasm (MCN) of pancreas is one of the precursor lesions of pancreatic ductal adenocarcinoma. The 5-year disease-specific survival for noninvasive MCNs was 100% and 20% to 60% for those with pancreatic ductal adenocarcinoma arising in a MCN. However, the significance of T1a (<=0.5 cm) and T1b (>0.5 and <1.0 cm) carcinoma arising in MCN as defined by the upcoming American Joint Committee on Cancer, eighth edition is unclear. In this study, we examined 3 cases of MCN with T1a or T1b carcinoma and compared their clinicopathologic characteristics and survival to 46 cases of MCN with low-grade dysplasia (MCN-LGD), 7 cases of MCN with high-grade dysplasia (MCN-HGD), and 7 cases of MCN with advanced invasive carcinoma (T2 or higher T stage). The tumors from all 3 cases were submitted in their entirety in 123, 296, and 200 blocks, respectively. All 3 patients were alive with no recurrence during the follow-up of 20.0, 113.8, and 137.2 months, respectively. Similarly, none of the patients who had MCN with either LGD or HGD had recurrence or died of disease. In contrast, 5 of 7 patients who had MCN with advanced invasive carcinoma had recurrence and later died of disease with a median survival of 22.9 months (P<0.001). Our study showed that MCN with T1a and T1b carcinoma had an excellent prognosis similar to MCNs with LGD or HGD after complete tumor sampling for histologic examination. Our results along with the previous studies suggest that close follow-up, rather than aggressive systemic therapy, may be a better approach for these patients. PMID- 29462093 TI - Contraception for midlife women: a review. AB - Family planning represents a key component of reproductive health care. Accordingly, the provision of contraception must span the reproductive age spectrum, including perimenopause. The risk of pregnancy is decreased, but not trivial, among women over 40 years of age. Evidence-based guidelines for contraceptive use can assist clinicians in counseling their patients in this population. Intrauterine contraception is one of the most effective methods and is safe to use in midlife women with few exceptions. Progestin-only contraception is another safe option for most midlife women because it is not associated with an increased risk of cardiovascular complications. Combined (estrogen-containing) contraception can be safely used by midlife women who do not have cardiovascular risk factors. Unique noncontraceptive benefits for this population include: improvement in abnormal uterine bleeding, decreased hot flashes, and decreased cancer risk. Finally, guidelines state that contraception can be used by midlife women without medical contraindications until the age of menopause, at which time they may consider transition to systemic hormone therapy. PMID- 29462094 TI - Effects of abaloparatide on bone mineral density and risk of fracture in postmenopausal women aged 80 years or older with osteoporosis. AB - OBJECTIVE: Advanced age is an important risk factor for fracture. The Abaloparatide Comparator Trial In Vertebral Endpoints (ACTIVE) trial showed that subcutaneous abaloparatide increased bone mineral density (BMD) and reduced the risk of vertebral and nonvertebral fractures in postmenopausal women with osteoporosis. This study describes the effects of abaloparatide in the subgroup of women aged 80 or more years in ACTIVE. METHODS: Post hoc analyses of BMD and fracture incidence in this subgroup of women who received abaloparatide or placebo in the 18-month, phase 3, double-blind, randomized controlled ACTIVE trial. RESULTS: The mean ages of the women >=80 years were 81.9 and 81.7 years in the placebo (n = 43) and abaloparatide (n = 51) groups, respectively. The increases in BMD from baseline to 18 months with abaloparatide treatment were 3.9% at the total hip (P < 0.001), 3.6% at the femoral neck (P < 0.01), and 12.1% at the lumbar spine (P < 0.001), and were similar to those observed in the overall population. Abaloparatide therapy was associated with numerical, but not statistically significant, reductions in the risk of vertebral and nonvertebral fractures in this subpopulation, compared with placebo. The proportion of participants reporting adverse events was similar between treatment groups and between the older subgroup and the overall population. CONCLUSION: Abaloparatide was effective in increasing BMD in the very elderly subgroup of ACTIVE, with a safety profile similar to that of the overall study population. PMID- 29462095 TI - Hormonal, metabolic, and endometrial safety of testosterone vaginal cream versus estrogens for the treatment of vulvovaginal atrophy in postmenopausal women: a randomized, placebo-controlled study. AB - OBJECTIVE: The aim of the study was to evaluate the laboratory and endometrial safety of topical testosterone versus topical estrogen for the treatment of vaginal atrophy in postmenopausal women. METHODS: This was a randomized, placebo controlled trial of 60 postmenopausal women aged 40 to 70 years at the Menopause Clinic of CAISM UNICAMP. Women were randomized into three vaginal treatment groups: estrogen, testosterone, or placebo. The treatment was applied 3 times a week for 12 weeks. Hormonal laboratory values of follicle-stimulating hormone, luteinizing hormone, estradiol, estrone, androstenedione, total testosterone, free testosterone, dehydroepiandrosterone, dehydroepiandrosterone sulfate, and sex hormone-binding globulin were assessed at baseline and at 6 and 12 weeks. Metabolic laboratory values of total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, and gamma glutamyl transpeptidase were also assessed at baseline and at 6 and 12 weeks. Endometrial safety was assessed using ultrasonography at baseline and at 12 weeks. RESULTS: After 12 weeks of treatment, there were no significant differences in hormonal or metabolic laboratory values among all three groups. Two participants in the estrogen group had increased serum estradiol after 12 weeks of treatment. No change in endometrial thickening was reported in all three groups. CONCLUSIONS: Twelve weeks of treatment with topical testosterone or estrogen in postmenopausal women with symptoms of vaginal atrophy demonstrated laboratory and endometrial safety when compared with placebo. PMID- 29462096 TI - Patterns of menopausal hormone therapy use and hyperkyphosis in older women. AB - OBJECTIVE: Hyperkyphosis, an exaggerated anterior curvature of the thoracic spine, is associated with poor physical function, falls, fractures, and earlier mortality. Low bone mineral density, bone loss, and vertebral fractures are strong risk factors for hyperkyphosis. Menopausal hormone therapy (HT) reverses bone loss, prevents vertebral fractures, and, therefore, we hypothesize, may reduce the risk for developing hyperkyphosis. METHODS: We evaluated the cross sectional association between Cobb angle of kyphosis from lateral spine radiographs and pattern of self-reported HT use during the prior 15-year period in 1,063 women from the Study of Osteoporotic Fractures. RESULTS: Participants had a mean age of 83.7 +/- 3.3 years and a mean Cobb angle of 51.3 +/- 14.6 degrees . Forty-six per cent of women were characterized as never-users of HT, 24% as remote past users, 17% as intermittent users, and 12% as continuous users. In minimally adjusted models, the mean Cobb angle was 4.0 degrees less in continuous HT users compared with never-users (P = 0.01); however, in fully adjusted models, this association was attenuated to 2.8 degrees (P = 0.06). Remote past HT users had 3.0 degrees less kyphosis compared with never-users in minimally adjusted models (P = 0.01), attenuated to 2.8 degrees less in fully adjusted models (P = 0.02). Intermittent users did not differ from never-users in degree of kyphosis. CONCLUSIONS: Women reporting continuous or remote past HT use had less pronounced kyphosis than never-users by their mid-eighties, suggesting a possible role for HT in the prevention of age-related hyperkyphosis. PMID- 29462097 TI - Detection of Spatiotemporal Asymmetry in Pro Level Soccer Players. AB - Knudsen, NS and Andersen, TB. Detection of spatiotemporal asymmetry in pro level soccer players. J Strength Cond Res 32(3): 798-804, 2018-Several papers have focused on change of direction (COD) asymmetry investigated through standardized tests, and used this information to provide some spatiotemporal insight during games. The aim of this study was to investigate asymmetry in the reachable areas of the players through actual position data from soccer games. Sixteen professional players from the Danish Superliga participated in this study, but 5 were excluded because of lack of participation throughout the investigated games. The reachable areas of the players were investigated at varying sprint velocities (1-7 m.s) and within varying time intervals (0.5-4 seconds). The analysis found 7 players having spatiotemporal asymmetries in their reachable areas (0.5-3%) and shift of center of reachable area (4-29 cm). Four players (LB, RB, DM, and CF) had spatiotemporal asymmetries that could be attributed to COD and thus physiological asymmetries, whereas 3 players (LCB, LW, and RW) had spatiotemporal asymmetries that might be caused by their position or by use of tactic. This type of asymmetry was named a tactical spatiotemporal asymmetry. Coaches with knowledge about spatiotemporal asymmetries can use these actively in their tactical approach using the players' asymmetries in synergy, using opponents' asymmetries or improving the existing postgame spatiotemporal analyzing tools.

PMID- 29462100 TI - Exercise Training in "At-Risk" Black and White Women: A Comparative Cohort Analyses. AB - PURPOSE: Few data on the effect of exercise interventions in black women at risk for cardiovascular disease are available. METHODS: Women >=18 yr of age without known cardiovascular disease with >=1 coronary risk factor were enrolled in a community-based exercise program >=3 d.wk for >=30 min per session for 6 months. Exercise training intensity ~50% to 80% of functional capacity, using heart rate (HR) and/or rating of perceived exertion (RPE) as the primary intensity modulators. Preconditioning versus postconditioning quality of life assessments (depression and level of daytime sleepiness), dietary fat intake, Duke Activity Status Index score, changes in cardiovascular efficiency (systolic/diastolic blood pressure (SBP/DBP), HR, RPE during a standardized submaximal workload), and anthropometric measures, including body weight, body mass index, and waist circumference, were evaluated. RESULTS: Of 556 volunteers, 143 were excluded, leaving 413 women (222 white, 191 black; mean +/- SD age, 61 +/- 9 yr) who met compliance criteria. Both groups demonstrated significant (P < 0.05) postconditioning decreases in body mass index, waist circumference, resting SBP/DBP, and total and LDL cholesterol, and reductions in HR, SBP/DBP, and RPE at a fixed submaximal workload, and in fat screener, depression, and sleep scores. Duke Activity Status Index scores increased significantly (P < 0.0001) for both groups, signifying increases in self-reported functional capacity. Although 87 women (21%) experienced a musculoskeletal injury/discomfort during the program, there were no exercise-related cardiovascular events. CONCLUSIONS: A progressive moderate-to-vigorous exercise intervention without preliminary exercise testing elicited comparable improvements in coronary risk factors, anthropometric and quality of life measures, and cardiovascular efficiency in "at-risk" black and white women. These adaptations were achieved at exercise levels below those recommended in contemporary physical activity guidelines. PMID- 29462101 TI - Predicting Diaphyseal Cortical Bone Status Using Measures of Muscle Force Capacity. AB - PURPOSE: Muscle cross-sectional area (MCSA) is often used as a surrogate for the forces applied to bones during physical activity. Although MCSA is a strong predictor of cortical bone status, its use makes assumptions about the relationship between muscle size and force that are inaccurate. Furthermore, to measure MCSA and other muscle force surrogates typically requires expensive and/or radiative laboratory equipment. Thus, this study aimed to determine whether clinical laboratory- and field-based methodologies for measuring muscular force capacity accounted for similar variance in diaphyseal cortical bone status as a commonly used muscular force surrogate, MCSA, at the midtibia in young men and women. METHODS: Healthy young adults (n = 142, 19.7 +/- 0.7 yr old, 52.8% female) were assessed via peripheral quantitative computed tomography at the midtibia for cortical bone status and MCSA. Muscle force capacity was measured via Biodex dynamometer, Nottingham leg extensor power rig, and Vertec vertical jump. Regression analysis compared the independent variance predicted by each muscle force measure with that of MCSA, accounting for relevant confounders. RESULTS: MCSA, knee extension peak torque, and peak anaerobic power from vertical jump were independent predictors of select cortical structural outcomes (cortical thickness and area, periosteal and endosteal circumference, and estimated strength) accounting for up to 78.4% of the variance explained (all P < 0.05). However, cortical volumetric bone mineral density was unrelated to any measure or surrogate of muscle force capacity. CONCLUSIONS: MCSA is a strong independent predictor of cortical bone structure; however, both laboratory- and field-based measures of peak torque and/or peak anaerobic power are promising alternatives, explaining similar and sometimes greater variance than MCSA. PMID- 29462102 TI - Physical Activity Alters Inflammation in Older Adults by Different Intensity Levels. AB - PURPOSE: To examine the influence of reallocating time spent at different objectively measured physical activity (PA) behaviors on markers of systemic inflammation in older women with different levels of metabolic risk. METHODS: Accelerometer-based monitoring of PA was conducted in a population of community dwelling older women (n = 111; age, 65-70 yr) for determination of daily sedentary time, time in light PA (LPA) and moderate-to-vigorous PA (MVPA). Blood samples were collected for the assessment of the systemic inflammatory markers C reactive protein (CRP), fibrinogen, and adiponectin. Metabolic risk was assessed by standardized procedures based on definitions for the metabolic syndrome. Data were analyzed by linear regression models based on isotemporal substitution analysis. RESULTS: Reallocating 30 min of sedentary time with either time in LPA (beta = -0.47; P < 0.05) or MVPA (beta = -0.42; P < 0.05) was related to reduced fibrinogen level, whereas no corresponding effect was evident when shifting time in LPA with time in MVPA, while holding sedentary time constant. In contrast, reallocating a 30-min period in sedentary (beta = -0.70; P < 0.01) or LPA (beta = -0.71; P < 0.01) with MVPA was associated with a significant reduction in CRP level, whereas no impact on CRP was observed when a period of sedentary behavior was replaced with LPA. Importantly, all significant influences on fibrinogen and CRP by displacement of different PA behaviors remained after adjustment for metabolic risk status among participants. No significant associations with adiponectin were observed. CONCLUSIONS: Altogether, this work supports the existence of different intensity thresholds mediating beneficial effects of PA on important clinical markers of systemic inflammation in older women across different stages of disease prevention. PMID- 29462103 TI - Hospital, Maternal and Birth Factors Associated With Hepatitis B Vaccination at Birth: West Virginia, 2015. AB - BACKGROUND: Hepatitis B virus is a bloodborne pathogen typically transmitted through sexual contact, injection drug use or perinatally. A hepatitis B vaccine (HepB) is available; the first dose is recommended at birth. We sought to identify hospital policy, maternal characteristics and birth factors associated with HepB receipt at birth in West Virginia. METHODS: We conducted a retrospective cohort study of West Virginia live births in 2015 using vital records matched to immunization registry records to determine frequency of HepB birth dose receipt (<3 days postdelivery). We surveyed all West Virginia birthing facilities in 2015 (N = 26) about perinatal hepatitis B virus prevention policies. We examined associations of hospital policy, maternal characteristics and birth factors with HepB receipt at birth by using a mixed-effects regression model to calculate adjusted prevalence ratios (aPRs) and 95% confidence intervals (CIs). RESULTS: Of 17,458 births, 14,006 (80.2%) infants received a HepB birth dose. Hospital use of preprinted newborn routine admission vaccination orders was associated with HepB birth dose receipt (aPR: 10.60; 95% CI: 2.12-52.72). Not using illicit drugs during pregnancy, maternal age <35 years and weekday births were associated with HepB birth dose receipt (aPR: 1.81; 95% CI: 1.54-2.13; aPR: 1.34, 95% CI: 1.17-1.54 and aPR: 1.15; 95% CI: 1.03-1.28, respectively). CONCLUSIONS: Hospitals using preprinted admission orders had higher frequencies of HepB birth dose receipt. Additional study is needed to identify HepB birth dose receipt barriers among infants with maternal illicit drug use, maternal age >=35 years or deliveries during a weekend. PMID- 29462104 TI - High Incidence of Tuberculosis Infection in HIV-exposed Children Exiting an Isoniazid Preventive Therapy Trial. AB - Young HIV-exposed children are at high risk for TB infection. We performed QuantiFERON-TB Gold among HIV-exposed children in South Africa at enrolment and 1 year follow-up. The incidence of TB infection was high for HIV+ (11 cases per 100 child-years) and HIV-exposed uninfected children (15 cases per 100 child-years). QuantiFERON-TB Gold may identify HIV-exposed children at risk for TB disease progression. PMID- 29462105 TI - Group A Streptococcal Brain Abscess in the Pediatric Population: Case Series and Review of the Literature. AB - BACKGROUND: Group A Streptococcus (GAS) is a rare cause of central nervous system infections. METHODS: We describe 3 new cases of GAS brain abscess in previously healthy children treated by us between 2015 and 2016 and review the 5 cases reported in the literature since 1988. RESULTS: All 8 children received early empiric antibiotic therapy and surgical intervention, and 5 made a full recovery. CONCLUSIONS: GAS brain abscess is a rare infection; however its incidence may be rising. We suggest that if patients show symptoms such as fever, vomiting and lethargy, with contiguous infection such as otitis media, mastoiditis, sinusitis or meningitis, GAS brain abscess should be suspected. Prognosis is expected to be good with early implementation of appropriate treatment. PMID- 29462106 TI - Prevalence of Occult Bacteremia in Infants With Very High Fever Without a Source. AB - We carried out a prospective registry-based cohort study at the emergency department of 363 previously healthy well-appearing infants 3-24 months of age with fever without a source >=40.5 degrees C based on local protocol. Four were diagnosed with occult bacteremia (1.1%; 95% confidence interval: 0-2.2). Recommendations for nontesting for occult bacteremia screening in these children may have to be reconsidered when fever >=40.5 degrees C. Larger studies are needed to confirm these results.

PMID- 29462108 TI - Disulfiram attenuates morphine or methadone withdrawal syndrome in mice. AB - Taking opioids is often accompanied by the development of dependence. Unfortunately, treatment of opioid dependence is difficult, particularly because of codependence - for example, on alcohol or other drugs of abuse. In the presented study, we analyzed the potential influence of disulfiram, a drug used to aid the management of alcoholism, on opioid abstinence syndrome, which occurs as a result of opioid withdrawal. Opioid dependence in mice was induced by subcutaneous administration of either morphine or methadone at a dose of 48 mg/kg for 10 consecutive days. To trigger a withdrawal syndrome, the opioid receptor antagonist, naloxone, was administered at a dose of 1 mg/kg (subcutaneous), and the severity of withdrawal signs was assessed individually. Interruption of chronic treatment with morphine or methadone by naloxone has led to the occurrence of opioid abstinence signs such as jumping, paw tremor, wet-dog shakes, diarrhea, teeth chattering, ptosis, and piloerection. Importantly, pretreatment with disulfiram (25, 50, and 100 mg/kg) reduced the intensity of withdrawal signs induced by naloxone in morphine or methadone-treated mice. These findings show the effectiveness of disulfiram in reducing opioid abstinence signs. PMID- 29462109 TI - Effects of the active constituents of Crocus sativus L. crocins and their combination with memantine on recognition memory in rats. AB - Crocus sativus L., is a plant cultivated in many countries of the world. Crocins are among the active constituents of C. sativus and their implication in cognition has been proposed. The present study was designed to investigate in the rat the effects of crocins on distinct recognition memory components (encoding, storage and retrieval). Subsequently, the potential use of crocins as adjunctive agents for the treatment of memory disorders was examined. Thus, the effects exerted by a combination of subthreshold doses of crocins and memantine on recognition memory were evaluated. To assess the effects of compounds on memory, the novel object-recognition task (NORT) was used. In a preliminary study, the influence of the retention time (the delay between the two trials) on the performance of rats was assessed. Rats' recognition memory abilities remained intact up to 6 h, but were extinguished when a delay of 24 h was utilized. Crocins, at any dose tested (5, 15, and 30 mg/kg), did not affect rats' performance, whereas administration of higher doses (15 and 30 mg/kg) reversed delay-dependent deficits in the NORT. The combination of subthreshold doses of crocins (5 mg/kg) and memantine (3 mg/kg) did not influence the performance, but counteracted delay-dependent deficits in the NORT. These findings suggest that crocins counteract natural forgetting and may modulate different aspects of recognition memory, and that the combined use of crocins and memantine might represent a novel strategy to treat memory disorders. PMID- 29462110 TI - Strain differences in the susceptibility to the gut-brain axis and neurobehavioural alterations induced by maternal immune activation in mice. AB - There is a growing realization that the severity of the core symptoms of autism spectrum disorders and schizophrenia is associated with gastrointestinal dysfunction. Nonetheless, the mechanisms underlying such comorbidities remain unknown. Several genetic and environmental factors have been linked to a higher susceptibility to neurodevelopmental abnormalities. The maternal immune activation (MIA) rodent model is a valuable tool for elucidating the basis of this interaction. We induced MIA with polyinosinic-polycytidylic acid (poly I:C) at gestational day 12.5 and assessed behavioural, physiological and molecular aspects relevant to the gut-brain axis in the offspring of an outbred (NIH Swiss) and an inbred (C57BL6/J) mouse strain. Our results showed that the specific MIA protocol employed induces social deficits in both strains. However, alterations in anxiety and depression-like behaviours were more pronounced in NIH Swiss mice. These strain-specific behavioural effects in the NIH Swiss mice were associated with marked changes in important components of gut-brain axis communication: the endocrine response to stress and gut permeability. In addition, MIA-induced changes in vasopressin receptor 1a mRNA expression in the hypothalamus were observed in NIH Swiss mice only. Taken together, these data suggest that genetic background is a critical factor in susceptibility to the gut-brain axis effects induced by MIA. PMID- 29462111 TI - Medication overuse headache following repeated morphine, but not [INCREMENT]9 tetrahydrocannabinol administration in the female rat. AB - The potential of [INCREMENT]-tetrahydrocannabinol (THC) as a treatment for migraine depends on antinociceptive efficacy with repeated administration. Although morphine has good antinociceptive efficacy, repeated administration causes medication overuse headache (MOH) - a condition in which the intensity/frequency of migraine increases. The present study compared the effect of repeated morphine or THC administration on the magnitude and duration of migraine-like pain induced by a microinjection of allyl isothiocyanate (AITC) onto the dura mater of female rats. Acute administration of THC or morphine prevented AITC-induced depression of wheel running. This antinociception was maintained in rats treated repeatedly with THC, but not following repeated administration of morphine. Moreover, repeated morphine, but not THC administration, extended the duration of AITC-induced depression of wheel running. These data indicate that tolerance and MOH develop rapidly to morphine administration. The lack of tolerance and MOH to THC indicates that THC may be an especially effective long-term treatment against migraine. PMID- 29462112 TI - Microinjection of the mGluR2/3 agonist, LY379268, into the nucleus accumbens attenuates extinction latencies and the reinstatement of morphine-induced conditioned place preference in rats. AB - Previous studies indicate that metabotropic glutamate receptor type 2/3 (mGluR2/3) has a key role in the rewarding properties of morphine-induced conditioning place preference (CPP). Group II mGluR2/3 agonists are offered as a drug addiction treatment. The nucleus accumbens (NAc), which is one of the important areas involved in the reward circuitry, also expresses these receptors. In this study, we evaluated the effects of mGluR2/3 agonist, LY379268, on the extinction and reinstatement of morphine-induced CPP, following its microinjection into the NAc. Adult male Wistar rats (220-250 g) were implanted bilaterally by two separate cannulae into the NAc. After the acquisition of morphine CPP, different doses of LY379268 (0.3, 1 and 3 ug/0.5 MUl saline) were microinjected into the NAc every day during the extinction period and, in a different set of experiments, on the reinstatement test day, 60 min before the infusion of a priming dose of morphine (1 mg/kg; subcutaneous). Thereafter, the animals were tested for place preference by the Ethovision software. The intra accumbal injection of the mGluR2/3 agonist, LY379268, significantly decreased the extinction latencies and reinstatement of morphine-induced CPP at higher doses. It seems that the NAc might be a functional region for mGluR2/3 to play a regulatory role for decreasing drug-seeking behavior in rats. Furthermore, it can be said that mGluR2/3 agonists have a potential role in the treatment of drug seeking behaviors. PMID- 29462113 TI - Use of open and endovascular surgical techniques to manage vascular injuries in the trauma setting: A review of the American Association for the Surgery of Trauma PROspective Observational Vascular Injury Trial registry. AB - BACKGROUND: Vascular trauma data have been submitted to the American Association for the Surgery of Trauma PROspective Observational Vascular Injury Trial (PROOVIT) database since 2013. We present data to describe current use of endovascular surgery in vascular trauma. METHODS: Registry data from March 2013 to December 2016 were reviewed. All trauma patients who had an injury to a named artery, except the forearm and lower leg, were included. Arteries were grouped into anatomic regions and by compressible and noncompressible region for analysis. This review focused on patients with noncompressible transection, partial transection, or flow-limiting defect injuries. Bivariate and multivariate analyses were used to assess the relationships between study variables. RESULTS: One thousand one hundred forty-three patients from 22 institutions were included. Median age was 32 years (interquartile range, 23-48) and 76% (n = 871) were male. Mechanisms of injury were 49% (n = 561) blunt, 41% (n = 464) penetrating, and 1.8% (n = 21) of mixed aetiology. Gunshot wounds accounted for 73% (n = 341) of all penetrating injuries. Endovascular techniques were used least often in limb trauma and most commonly in patients with blunt injuries to more than one region. Penetrating wounds to any region were preferentially treated with open surgery (74%, n = 341/459). The most common indication for endovascular treatment was blunt noncompressible torso injuries. These patients had higher Injury Severity Scores and longer associated hospital stays, but required less packed red blood cells, and had lower in hospital mortality than those treated with open surgery. On multivariate analysis, admission low hemoglobin concentration and abdominal injury were independent predictors of mortality. CONCLUSION: Our review of PROOVIT registry data demonstrates a high utilization of endovascular therapy among severely injured blunt trauma patients primarily with noncompressible torso hemorrhage. This is associated with a decreased need for blood transfusion and improved survival despite longer length of stay. LEVEL OF EVIDENCE: Therapeutic/care management, level III.

AB - BACKGROUND: Supracondylar humeral fractures (SCHF) are the most common elbow fractures in children. The epidemiology of these injuries in the United States is described. METHODS: The Nationwide Emergency Department Sample database was queried for all children (age, below 18 y) with SCHF treated in the emergency department (ED) from 2006 to 2011, and weighted estimates were extracted. RESULTS: A total of 63,348 ED visits for SCHF were identified. The weighted estimate of ED visits remained stable over the study period, ranging from 60.3 to 71.8 per 100,000 children annually. There was no significant difference in fracture rate (52% male) by sex. The mean age of closed injury was 5.5+/-3.1 years, with 53.6% of fractures occurring in children 3 to 6 years. Open injuries accounted for 1.0% of fractures. Children with open injuries were significantly older (mean, 9.1+/-4.4 y; P<0.0001) and more often male (OR, 1.43; P<0.001). Neurovascular injury occurred in significantly older children (mean, 7.6+/-3.1 y; P<0.0001) and was documented in 11.4% of open fractures and 3.6% of operative fractures. Although the South had the greatest number of total SCHF-related ED visits, children in the West had significantly more SCHF-related ED visits per 100,000 children annually (77.9) than all other regions (P<0.05). Average fracture rates were approximately 60% higher in April to September than October to March (P<0.001). Mean total charges for patients treated and discharged from the ED were $2965, compared with $17,865 in children admitted for surgery (P<0.05). Mean charges were significantly higher in the West compared with all other regions (P<0.0001). CONCLUSIONS: The incidence of pediatric SCHF-related ED visits remained stable from 2006 to 2011 and occurred most frequently in children aged 3 to 6 years. Open injuries are rare and are more likely to occur in older boys. There are significant differences in the injury rates and charges across geographic regions, identifying opportunities for injury prevention, cost reduction, and value improvement. The indications for operative management should be clearly delineated given the high cost of surgical treatment. LEVEL OF EVIDENCE: Therapeutic Level IV. PMID- 29462119 TI - Comparison of Methicillin-resistant Versus Susceptible Staphylococcus aureus Pediatric Osteomyelitis. AB - BACKGROUND: The incidence of methicillin-resistant Staphylococcus aureus (MRSA) pediatric osteomyelitis has risen and been associated with a more severe clinical course than methicillin-susceptible Staphylococcus aureus (MSSA) infections. National databases have been underutilized to describe these trends. We compared demographics, clinical course, and outcomes for patients with MRSA versus MSSA osteomyelitis. METHODS: We queried the 2009 and 2012 Healthcare Cost and Utilization Project Kids Inpatient Database for discharge records with diagnosis codes for osteomyelitis and S. aureus. We explored demographics predicting MRSA and evaluated MRSA versus MSSA as predictors of clinical outcomes including surgery, sepsis, thrombophlebitis, length of stay, and total charges. RESULTS: A total of 4214 discharge records were included. Of those, 2602 (61.7%) had MSSA and 1612 (38.3%) had MRSA infections. Patients at Southern and Midwestern hospitals were more likely to have MRSA than those at Northeastern hospitals. Medicaid patients' odds of MRSA were higher than those with private insurance, and black patients were more likely to have MRSA compared with white patients. MRSA patients were more likely to undergo multiple surgeries compared with MSSA patients and were more likely to have complications including severe sepsis, thrombophlebitis, and pulmonary embolism. Patients with MRSA had longer lengths of stay than those with MSSA and higher total charges after controlling for length of stay. CONCLUSION: Review of a national database demonstrates MRSA is more prevalent in the South and Midwest regions and among black patients. MRSA patients have more surgeries, complications, and longer lengths of stay. LEVEL OF EVIDENCE: Level III. PMID- 29462121 TI - Patient Mortality in Geriatric Distal Femur Fractures. AB - OBJECTIVES: To estimate 1-year mortality rates in elderly patients who undergo operative treatment for distal femur fractures and identify potential risk factors for mortality. DESIGN: Retrospective chart review. SETTING: Level 1 and Level 2 trauma centers. PATIENTS/PARTICIPANTS: Two hundred eighty-three elderly patients (average age 76.0 years +/- 9.8) who sustained distal femur fractures between 2002 and 2012. INTERVENTION: Fracture fixation of the distal femur. MAIN OUTCOME MEASURE: Survival up to 1 year after surgery. RESULTS: The 1-year mortality rate for distal femur fractures in elderly patients was 13.4%. There were no statistically significant differences in overall mortality between native bone and periprosthetic fractures, intramedullary nail or open reduction internal fixation, or across Orthopaedic Trauma Association fracture classifications. Overall patient mortality was significantly higher at 30 days (P = 0.036), 6 months (P = 0.019), and 1 year (P = 0.018), when surgery occurred more than 2 days from the injury. Mean Charlson Comorbidity Index scores were significantly lower in survivors versus nonsurvivors at all time intervals (30 days, P = 0.023; 6 months, P = 0.001 and 1 year P <= 0.001). A time to surgery of more than 2 days, regardless of baseline illness, did not result in improved survivability at 1 year. CONCLUSIONS: Overall mortality for distal femur fractures was 13.4% in the elderly population. A surgical treatment more than 2 days after injury was associated with increased patient mortality. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence. PMID- 29462122 TI - Risk of Hip Arthroplasty After Open Reduction Internal Fixation of a Fracture of the Acetabulum: A Matched Cohort Study. AB - OBJECTIVES: To determine what proportion of operatively treated acetabular fracture patients proceeded to total hip arthroplasty (THA), over what time period, and quantify the influence of patient, provider, and surgical factors on rates of THA. DESIGN: Retrospective matched cohort prognostic study using administrative data. SETTING: This study used the large population database of Ontario (population 13,125,000 in 2010), Canada. PARTICIPANTS: Patients who underwent open reduction internal fixation (ORIF) of an acetabulum fracture between 1996 and 2010 in the province of Ontario were identified from administrative health databases. METHOD: Each patient was matched to 4 individuals from the general population according to age, sex, income, and urban/rural residence. The rates of THA at 2, 5, and 10 years were compared using time-to-event analysis. The influence of patient, provider, and surgical factors on the risk of eventual THA was examined using a Cox model. INTERVENTION: The primary intervention was ORIF of the acetabulum. MAIN OUTCOME MEASUREMENT: The primary outcome measurement was THA. RESULTS: A total of 1725 eligible patients were identified and were matched to 6900 controls. Among cases, there was a 13.9% (N = 240) rate of hip arthroplasty after a median of 6.25 (interquartile range 3.5-10.1) years, compared with 0.6% (N = 38) among matched controls (relative risk = 25.26). The greatest difference in risk of eventually undergoing a THA was in the first 10 years, after which time the risk in the group that had undergone ORIF acetabulum trended down toward that of the control group. Among surgical patients, risk factors for eventual hip arthroplasty included older age [hazard ratio (HR) 1.035 (1.027, 1.044); P < 0.0001]; female sex [HR 1.65 (1.257, 2.165); P = 0.0003]. Higher surgeon volume revealed a 2.6% decreased risk of arthroplasty for each acetabulum ORIF performed above 10 per year [HR 0.974 (0.960, 0.989); P = 0.0007]. CONCLUSION: Patients who underwent acetabulum fracture ORIF had a 25 times higher prevalence of hip arthroplasty compared with matched controls. THA rate was greater in women, older patients, and patients whom had ORIF performed by low-volume surgeons. LEVEL OF EVIDENCE: Prognostic Level II.

PMID- 29462124 TI - Impact of United States Preventive Services Task Force Recommendations on Utilization of Prostate-specific Antigen Screening in Medicare Beneficiaries. AB - BACKGROUND: Previous studies assessing the impact of United States Preventive Services Task Force (USPSTF) recommendations on utilization of prostate-specific antigen (PSA) screening have not investigated longer-term impacts of 2008 recommendations nor have they investigated the impact of 2012 recommendations in the Medicare population. This study aimed to evaluate change in utilization of PSA screening, post-2008 and 2012 USPSTF recommendations, and assessed trends and determinants of receipt of PSA screening in the Medicare population. METHODS: This retrospective study of male Medicare beneficiaries utilized Medicare Current Beneficiary Survey data and linked administrative claims from 2006 to 2013. Beneficiaries aged >=65 years, with continuous enrollment in parts A and B for each year they were surveyed were included in the study. Beneficiaries with self reported/claims-based diagnosis of prostate cancer were excluded. The primary outcome was receipt of PSA screening. Other measures included age groups (65 to 74 and >=75), time periods (pre-2008/post-2008 and 2012 recommendations), and sociodemographic variables. RESULTS: The study cohort consisted of 11,028 beneficiaries, who were predominantly white (87.56%), married (69.25%), and unemployed (84.4%); 52.21% beneficiaries were aged >=75. Declining utilization trends for PSA screening were observed in men aged >=75 after 2008 recommendations and in both age groups after 2012 recommendations. The odds of receiving PSA screening declined by 17% in men aged >=75 after 2008 recommendations and by 29% in men aged >=65 after 2012 recommendations. CONCLUSIONS: The 2008 and 2012 USPSTF recommendations against PSA screening were associated with declines in utilization of PSA screening during the study period. USPSTF recommendations play a significant role in affecting utilization patterns of health services. PMID- 29462123 TI - Pembrolizumab for the Treatment of Advanced Salivary Gland Carcinoma: Findings of the Phase 1b KEYNOTE-028 Study. AB - OBJECTIVES: Treatment options for patients with unresectable or metastatic salivary gland carcinoma (SGC) are limited. Safety and efficacy of pembrolizumab for SGC expressing programmed death ligand 1 (PD-L1) were explored. MATERIALS AND METHODS: A cohort of patients with advanced, PD-L1-positive SGC was enrolled in the nonrandomized, multicohort, phase Ib trial of pembrolizumab in patients with PD-L1-positive advanced solid tumors (KEYNOTE-028; NCT02054806). Key inclusion criteria included recurrent or metastatic disease, failure of prior systemic therapy, and PD-L1 expression on >=1% of tumor or stroma cells (per a prototype immunohistochemistry assay). Patients received pembrolizumab 10 mg/kg every 2 weeks for >=2 years or until confirmed disease progression or unacceptable toxicity. Primary end point was objective response rate per Response Evaluation Criteria in Solid Tumors version 1.1 by investigator review. RESULTS: Twenty-six patients with PD-L1-positive SGC were enrolled and treated; median age was 57 years, 88% were men, and 74% had received prior therapy for recurrent/metastatic disease. Confirmed objective response rate after median follow-up of 20 months was 12% (95% confidence interval, 2%-30%), with 3 patients achieving partial response; there were no complete responses. Median duration of response was 4 months (range, 4 to 21 mo). Treatment-related adverse events occurred in 22 patients (85%), resulting in discontinuation in 2 patients and death in 1 (interstitial lung disease); those occurring in >=15% of patients were diarrhea, decreased appetite, pruritus, and fatigue. CONCLUSIONS: Pembrolizumab demonstrated promising antitumor activity and a manageable safety profile in patients with advanced, PD-L1-positive SGC.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

PMID- 29462125 TI - Increased Expression of TREK-1 K+ Channel in the Dorsal Root Ganglion of Rats with Detrusor Overactivity After Partial Bladder Outlet Obstruction. AB - BACKGROUND Changes in expression and activity of ion channels are important pathophysiological mechanisms underlying detrusor overactivity (DO) in partial bladder outlet obstruction (PBOO). The objective of this study was to examine the expression of TREK-1 channel in the bladder and central nervous system of DO rats. MATERIAL AND METHODS Thirty Sprague-Dawley rats were subjected to PBOO operations and those displaying non-voiding contractions (NVCs) in cystometry were classified as DO. Sham-operated rats without NVCs in cystometry served as controls. The expression and distribution of TREK-1 in the bladder, spinal cord, and dorsal root ganglion (DRG) were detected by real time-PCR, western blot, and immunohistochemistry. RESULTS TREK-1 channel expression in the DRG was significantly increased at the mRNA level (11.20+/-3.762 vs. 3.209+/-1.505, P<0.01) and protein level (2.195+/-0.058 vs. 1.713+/-0.066, P<0.01) in DO rats as compared to control rats. However, the expression of TREK-1 mRNA in the bladder (1.380+/-0.810 vs. 4.206+/-3.827, P>0.05) and spinal cord (0.764+/-0.357 vs. 0.696+/-0.188, P>0.05) was comparable between the 2 groups. Immunohistochemistry showed enhanced immunoreactive signals of TREK-1 channel in the DRG, but not in the spinal cord and bladder. CONCLUSIONS TREK-1 channel was upregulated in the DRG of DO rats after chronic PBOO, which might suppress neuronal excitability and play a protective role in bladder overactivity in PBOO.

AB - Background:The intratumoural heterogeneity, often driven by epithelial-to mesenchymal transition (EMT), significantly contributes to chemoresistance and disease progression in adenocarcinomas.Methods:We introduced a high-throughput screening platform to identify surface antigens that associate with epithelial mesenchymal plasticity in well-defined pairs of epithelial cell lines and their mesenchymal counterparts. Using multicolour flow cytometry, we then analysed the expression of 10 most robustly changed antigens and identified a 10-molecule surface signature, in pan-cytokeratin-positive/EpCAM-positive and -negative fractions of dissociated breast tumours.Results:We found that surface CD9, CD29, CD49c, and integrin beta5 are lost in breast cancer cells that underwent EMT in vivo. The tetraspanin family member CD9 was concordantly downregulated both in vitro and in vivo and associated with epithelial phenotype and favourable prognosis.Conclusions:We propose that overall landscape of 10-molecule surface signature expression reflects the epithelial-mesenchymal plasticity in breast cancer.

PMID- 29462133 TI - Clinical characteristics and epidemiology of intestinal tapeworm infections over the last decade in Tokyo, Japan: A retrospective review. AB - BACKGROUND: Tapeworm (cestode) infections occur worldwide even in developed countries and globalization has further complicated the epidemiology of such infections. Nonetheless, recent epidemiological data on cestode infections are limited. Our objectives were to elucidate the clinical characteristics and epidemiology of diphyllobothriosis and taeniosis in Tokyo, Japan. METHODOLOGY/PRINCIPAL FINDINGS: We retrospectively reviewed 24 cases of human intestinal cestode infection from January 2006 to December 2015 at a tertiary referral hospital in Tokyo, Japan. The patients included were diagnosed with cestode infection based on morphological and/or molecular identification of expelled proglottids and/or eggs and treated in our hospital. Fifteen and 9 patients were diagnosed with diphyllobothriosis and taeniosis, respectively. The median patient age was 31 years (interquartile range [IQR]: 26-42 years), and 13 (54%) were male. Most of the patients (91.7%) were Japanese. All patients were successfully treated with praziquantel without recurrence. Diphyllobothriosis was caused by Diphyllobothrium nihonkaiense in all patients. Taeniosis was due to infection of Taenia saginata in 8 [88.9%] patients and T. asiatica in 1 [11.1%] patient. All patients with taeniosis were infected outside Japan, as opposed to those with diphyllobothriosis, which were domestic. The source locations of taeniosis were mostly in developing regions. The median duration of the stay of the patients with taeniosis at the respective source location was 1 month (IQR: 1 8). CONCLUSIONS/SIGNIFICANCE: The cestode infection, especially with D. nihonkaiense, has frequently occurred, even in Japanese cities, thereby implicating the probable increase in the prevalence of diphyllobothriosis among travelers, as the number of travelers is expected to increase owing to the Tokyo Olympics/Paralympics in 2020. In addition, medical practitioners should be aware of the importance of providing advice to travelers to endemic countries of taeniosis, including the potential risks of infection and preventive methods for these infections. PMID- 29462134 TI - An insight into the salivary gland and fat body transcriptome of Panstrongylus lignarius (Hemiptera: Heteroptera), the main vector of Chagas disease in Peru. AB - Triatomines are hematophagous arthropod vectors of Trypanosoma cruzi, the causative agent of Chagas Disease. Panstrongylus lignarius, also known as Panstrongylus herreri, is considered one of the most versatile triatomines because it can parasitize different hosts, it is found in different habitats and countries, it has sylvatic, peridomestic and domestic behavior and it is a very important vector of Chagas disease, especially in Peru. Molecules produced and secreted by salivary glands and fat body are considered of important adaptational value for triatomines because, among other functions, they subvert the host haemostatic, inflammatory and immune systems and detoxify or protect them against environmental aggressors. In this context, the elucidation of the molecules produced by these tissues is highly valuable to understanding the ability of this species to adapt and transmit pathogens. Here, we use high-throughput sequencing techniques to assemble and describe the coding sequences resulting from the transcriptome of the fat body and salivary glands of P. lignarius. The final assembly of both transcriptomes together resulted in a total of 11,507 coding sequences (CDS), which were mapped from a total of 164,676,091 reads. The CDS were subdivided according to their 10 folds overexpression on salivary glands (513 CDS) or fat body (2073 CDS). Among the families of proteins found in the salivary glands, lipocalins were the most abundant. Other ubiquitous families of proteins present in other sialomes were also present in P. lignarius, including serine protease inhibitors, apyrase and antigen-5. The unique transcriptome of fat body showed proteins related to the metabolic function of this organ. Remarkably, nearly 20% of all reads mapped to transcripts coded by Triatoma virus. The data presented in this study improve the understanding on triatomines' salivary glands and fat body function and reveal important molecules used in the interplay between vectors and vertebrate hosts. PMID- 29462136 TI - DNA methylation profiling of genomic DNA isolated from urine in diabetic chronic kidney disease: A pilot study. AB - AIM: To characterise the genomic DNA (gDNA) yield from urine and quality of derived methylation data generated from the widely used Illuminia Infinium MethylationEPIC (HM850K) platform and compare this with buffy coat samples. BACKGROUND: DNA methylation is the most widely studied epigenetic mark and variations in DNA methylation profile have been implicated in diabetes which affects approximately 415 million people worldwide. METHODS: QIAamp Viral RNA Mini Kit and QIAamp DNA micro kit were used to extract DNA from frozen and fresh urine samples as well as increasing volumes of fresh urine. Matched buffy coats to the frozen urine were also obtained and DNA was extracted from the buffy coats using the QIAamp DNA Mini Kit. Genomic DNA of greater concentration than 20MUg/ml were used for methylation analysis using the HM850K array. RESULTS: Irrespective of extraction technique or the use of fresh versus frozen urine samples, limited genomic DNA was obtained using a starting sample volume of 5ml (0-0.86MUg/mL). In order to optimize the yield, we increased starting volumes to 50ml fresh urine, which yielded only 0-9.66MUg/mL A different kit, QIAamp DNA Micro Kit, was trialled in six fresh urine samples and ten frozen urine samples with inadequate DNA yields from 0-17.7MUg/mL and 0-1.6MUg/mL respectively. Sufficient genomic DNA was obtained from only 4 of the initial 41 frozen urine samples (10%) for DNA methylation profiling. In comparison, all four buffy coat samples (100%) provided sufficient genomic DNA. CONCLUSION: High quality data can be obtained provided a sufficient yield of genomic DNA is isolated. Despite optimizing various extraction methodologies, the modest amount of genomic DNA derived from urine, may limit the generalisability of this approach for the identification of DNA methylation biomarkers of chronic diabetic kidney disease. PMID- 29462135 TI - Accomplishing the genotype-specific serodiagnosis of single and dual Trypanosoma cruzi infections by flow cytometry Chagas-Flow ATE-IgG2a. AB - The methods currently available for genotype-specific diagnosis of T. cruzi infection still present relevant limitations, especially to identify mixed infection. In the present investigation, we have evaluated the performance of Chagas-Flow ATE-IgG2a test for early and late differential diagnosis of single and dual genotype-specific T. cruzi infections. Serum samples from Swiss mice at early and late stages of T. cruzi infection were assayed in parallel batches for genotype-specific diagnosis of single (TcI, TcVI or TcII) and dual (TcI+TcVI, TcVI+TcII or TcII+TcI) infections. The intrinsic reactivity to TcI, TcVI and TcII target antigens, including amastigote (AI/AVI/AII), trypomastigote-(TI/TVI/TII) and epimastigote (EI/EVI/EII), at specific reverse of serum dilutions (500 to 64,000), was employed to provide reliable decision-trees for "early" vs "late", "single vs "dual" and "genotype-specific" serology. The results demonstrated that selective set of attributes "EII 500/EI 2,000/AII 500" were able to provide high quality accuracy (81%) to segregate early and late stages of T. cruzi infection. The sets "TI 2,000/AI 1,000/EII 1,000" and "TI 8,000/AII 32,000" presented expressive scores to discriminate single from dual T. cruzi infections at early (85%) and late stages (84%), respectively. Moreover, the attributes "TI 4,000/TVI 500/TII 1,000", "TI 16,000/EI 2,000/EII 2,000/AI 500/TVI 500" showed good performance for genotype-specific diagnosis at early stage of single (72%) and dual (80%) T. cruzi infections, respectively. In addition, the attributes "TI 4,000/AII 1,000/EVI 1,000", "TI 64,000/AVI 500/AI 2,000/AII 1,000/EII 4,000" showed moderate performance for genotype-specific diagnosis at late stage of single (69%) and dual (76%) T. cruzi infections, respectively. The sets of decision-trees were assembled to construct a sequential algorithm with expressive accuracy (81%) for serological diagnosis of T. cruzi infection. These findings engender new perspectives for the application of Chagas-Flow ATE-IgG2a method for genotype-specific diagnosis in humans, with relevant contributions for epidemiological surveys as well as clinical and post-therapeutic monitoring of Chagas disease. PMID- 29462137 TI - The premammillary nucleus of the hypothalamus is not necessary for photoperiodic timekeeping in female turkeys (Meleagris gallopavo). AB - In birds, seasonal reproduction is regulated by day length, with long days in the spring activating the hypothalamic-pituitary-gonadal axis and reproductive behaviors. The photoreceptors mediating this process remain unknown, but recently, the premammillary nucleus (PMM) of the hypothalamus has been implicated as the site of photoperiodic signaling in turkeys. We performed electrolytic lesions of the PMM to elucidate its role in the photoactivation and maintenance of egg production in female turkeys. Our results show that ablation of the PMM does not alter the normal lay cycle. No differences were found between lesioned birds and sham controls in the latency to lay following photostimulation, nor in subsequent egg production over a period of 29 weeks. No differences in the incidence of gonadal regression were found, indicating that the PMM is not essential for the termination of breeding. We conclude that any role of the PMM in photoperiodic regulation, if it exists, is redundant with other components of the system. PMID- 29462138 TI - The 2014-2015 Ebola virus disease outbreak and primary healthcare delivery in Liberia: Time-series analyses for 2010-2016. AB - BACKGROUND: The aim of this study is to estimate the immediate and lasting effects of the 2014-2015 Ebola virus disease (EVD) outbreak on public-sector primary healthcare delivery in Liberia using 7 years of comprehensive routine health information system data. METHODS AND FINDINGS: We analyzed 10 key primary healthcare indicators before, during, and after the EVD outbreak using 31,836 facility-month service outputs from 1 January 2010 to 31 December 2016 across a census of 379 public-sector health facilities in Liberia (excluding Montserrado County). All indicators had statistically significant decreases during the first 4 months of the EVD outbreak, with all indicators having their lowest raw mean outputs in August 2014. Decreases in outputs comparing the end of the initial EVD period (September 2014) to May 2014 (pre-EVD) ranged in magnitude from a 67.3% decrease in measles vaccinations (95% CI: -77.9%, -56.8%, p < 0.001) and a 61.4% decrease in artemisinin-based combination therapy (ACT) treatments for malaria (95% CI: -69.0%, -53.8%, p < 0.001) to a 35.2% decrease in first antenatal care (ANC) visits (95% CI: -45.8%, -24.7%, p < 0.001) and a 38.5% decrease in medroxyprogesterone acetate doses (95% CI: -47.6%, -29.5%, p < 0.001). Following the nadir of system outputs in August 2014, all indicators showed statistically significant increases from October 2014 to December 2014. All indicators had significant positive trends during the post-EVD period, with every system output exceeding pre-Ebola forecasted trends for 3 consecutive months by November 2016. Health system outputs lost during and after the EVD outbreak were large and sustained for most indicators. Prior to exceeding pre-EVD forecasted trends for 3 months, we estimate statistically significant cumulative losses of -776,110 clinic visits (95% CI: -1,480,896, -101,357, p = 0.030); -24,449 bacille Calmette Guerin vaccinations (95% CI: -45,947, -2,020, p = 0.032); -9,129 measles vaccinations (95% CI: -12,312, -5,659, p < 0.001); -17,191 postnatal care (PNC) visits within 6 weeks of birth (95% CI: -28,344, -5,775, p = 0.002); and -101,857 ACT malaria treatments (95% CI: -205,839, -2,139, p = 0.044) due to the EVD outbreak. Other outputs showed statistically significant cumulative losses only through December 2014, including losses of -12,941 first pentavalent vaccinations (95% CI: -20,309, -5,527, p = 0.002); -5,122 institutional births (95% CI: 8,767, -1,234, p = 0.003); and -45,024 acute respiratory infections treated (95% CI: -66,185, -24,019, p < 0.001). Compared to pre-EVD forecasted trends, medroxyprogesterone acetate doses and first ANC visits did not show statistically significant net losses. ACT treatment for malaria was the only indicator with an estimated net increase in system outputs through December 2016, showing an excess of +78,583 outputs (95% CI: -309,417, +450,661, p = 0.634) compared to pre-EVD forecasted trends, although this increase was not statistically significant. However, comparing December 2013 to December 2017, ACT malaria cases have increased 49.2% (95% CI: 33.9%, 64.5%, p < 0.001). Compared to pre-EVD forecasted trends, there remains a statistically significant loss of -15,144 PNC visits within 6 weeks (95% CI: -29,453, -787, p = 0.040) through December 2016. CONCLUSIONS: The Liberian public-sector primary healthcare system has made strides towards recovery from the 2014-2015 EVD outbreak. All primary healthcare indicators tracked have recovered to pre-EVD levels as of November 2016. Yet, for most indicators, it took more than 1 year to recover to pre-EVD levels. During this time, large losses of essential primary healthcare services occurred compared to what would have been expected had the EVD outbreak not occurred. The disruption of malaria case management during the EVD outbreak may have resulted in increased malaria cases. Large and sustained investments in public-sector primary care health system strengthening are urgently needed for EVD-affected countries.

Seed germination is tightly controlled by the balance of gibberellin (GA) and abscisic acid (ABA), and is influenced by environmental factors. The COP9 Signalosome (CSN) is a conserved multi-subunit protein complex that is best known as a regulator of the Cullin-RING family of ubiquitin E3 ligases (CRLs). Multiple viable mutants of the CSN showed poor germination, except for csn5b-1. Detailed analyses showed that csn1-10 has a stronger seed dormancy, while csn5a-1 mutants exhibit retarded seed germination in addition to hyperdormancy. Both csn5a-1 and csn1-10 plants show defects in the timely removal of the germination inhibitors: RGL2, a repressor of GA signaling, and ABI5, an effector of ABA responses. We provide genetic evidence to demonstrate that the germination phenotype of csn1-10 is caused by over-accumulation of RGL2, a substrate of the SCF (CRL1) ubiquitin E3 ligase, while the csn5a-1 phenotype is caused by over-accumulation of RGL2 as well as ABI5. The genetic data are consistent with the hypothesis that CSN5A regulates ABI5 by a mechanism that may not involve CSN1. Transcriptome analyses suggest that CSN1 has a more prominent role than CSN5A during seed maturation, but CSN5A plays a more important role than CSN1 during seed germination, further supporting the functional distinction of these two CSN genes. Our study delineates the molecular targets of the CSN complex in seed germination, and reveals that CSN5 has additional functions in regulating ABI5, thus the ABA signaling pathway. PMID- 29462140 TI - DNA damage as a consequence of NLR activation. AB - DNA damage observed during plant immune responses is reported to be an intrinsic component of plant immunity. However, other immune responses may suppress DNA damage to maintain host genome integrity. Here, we show that immunity-related DNA damage can be abrogated by preventing cell death triggered by Nucleotide-binding, Leucine-rich-repeat immune Receptors (NLRs). SNI1 (suppressor of npr1-1, inducible 1), a subunit of the structural maintenance of chromosome (SMC) 5/6 complex, was reported to be a negative regulator of systemic acquired resistance (SAR) and to be necessary for controlling DNA damage. We find that cell death and DNA damage in sni1 loss-of-function mutants are prevented by mutations in the NLR signaling component EDS1. Similar to sni1, elevated DNA damage is seen in other autoimmune mutants with cell death lesions, including camta3, pub13 and vad1, but not in dnd1, an autoimmune mutant with no visible cell death. We find that as in sni1, DNA damage in camta3 is EDS1-dependent, but that it is also NLR-dependent. Using the NLR RPM1 as a model, we also show that extensive DNA damage is observed when an NLR is directly triggered by effectors. We also find that the expression of DNA damage repair (DDR) genes in mutants with cell death lesions is down regulated, suggesting that degraded DNA that accumulates during cell death is a result of cellular dismantling and is not sensed as damaged DNA that calls for repair. Our observations also indicate that SNI1 is not directly involved in SAR or DNA damage accumulation. PMID- 29462141 TI - The Mediator co-activator complex regulates Ty1 retromobility by controlling the balance between Ty1i and Ty1 promoters. AB - The Ty1 retrotransposons present in the genome of Saccharomyces cerevisiae belong to the large class of mobile genetic elements that replicate via an RNA intermediary and constitute a significant portion of most eukaryotic genomes. The retromobility of Ty1 is regulated by numerous host factors, including several subunits of the Mediator transcriptional co-activator complex. In spite of its known function in the nucleus, previous studies have implicated Mediator in the regulation of post-translational steps in Ty1 retromobility. To resolve this paradox, we systematically examined the effects of deleting non-essential Mediator subunits on the frequency of Ty1 retromobility and levels of retromobility intermediates. Our findings reveal that loss of distinct Mediator subunits alters Ty1 retromobility positively or negatively over a >10,000-fold range by regulating the ratio of an internal transcript, Ty1i, to the genomic Ty1 transcript. Ty1i RNA encodes a dominant negative inhibitor of Ty1 retromobility that blocks virus-like particle maturation and cDNA synthesis. These results resolve the conundrum of Mediator exerting sweeping control of Ty1 retromobility with only minor effects on the levels of Ty1 genomic RNA and the capsid protein, Gag. Since the majority of characterized intrinsic and extrinsic regulators of Ty1 retromobility do not appear to effect genomic Ty1 RNA levels, Mediator could play a central role in integrating signals that influence Ty1i expression to modulate retromobility. PMID- 29462143 TI - Prescriptive variability of drugs by general practitioners. AB - Prescription drug spending is growing faster than any other sector of healthcare. However, very little is known about patterns of prescribing and cost of prescribing between general practices. In this study, we examined variation in prescription rates and prescription costs through time for 55 GP surgeries in Northern Ireland Western Health and Social Care Trust. Temporal changes in variability of prescribing rates and costs were assessed using the Mann-Kendall test. Outlier practices contributing to between practice variation in prescribing rates were identified with the interquartile range outlier detection method. The relationship between rates and cost of prescribing was explored with Spearman's statistics. The differences in variability and mean number of prescribing rates associated with the practice setting and socioeconomic deprivation were tested using t-test and F-test respectively. The largest between-practice difference in prescribing rates was observed for Apr-Jun 2015, with the number of prescriptions ranging from 3.34 to 8.36 per patient. We showed that practices with outlier prescribing rates greatly contributed to between-practice variability. The largest difference in prescribing costs was reported for Apr-Jun 2014, with the prescription cost per patient ranging from L26.4 to L64.5. In addition, the temporal changes in variability of prescribing rates and costs were shown to undergo an upward trend. We demonstrated that practice setting and socio-economic deprivation accounted for some of the between-practice variation in prescribing. Rural practices had higher between practice variability than urban practices at all time points. Practices situated in more deprived areas had higher prescribing rates but lower variability than those located in less deprived areas. Further analysis is recommended to assess if variation in prescribing can be explained by demographic characteristics of patient population and practice features. Identification of other factors contributing to prescribing variability can help us better address potential inappropriateness of prescribing. PMID- 29462142 TI - RNF8 and SCML2 cooperate to regulate ubiquitination and H3K27 acetylation for escape gene activation on the sex chromosomes. AB - The sex chromosomes are enriched with germline genes that are activated during the late stages of spermatogenesis. Due to meiotic sex chromosome inactivation (MSCI), these sex chromosome-linked genes must escape silencing for activation in spermatids, thereby ensuring their functions for male reproduction. RNF8, a DNA damage response protein, and SCML2, a germline-specific Polycomb protein, are two major, known regulators of this process. Here, we show that RNF8 and SCML2 cooperate to regulate ubiquitination during meiosis, an early step to establish active histone modifications for subsequent gene activation. Double mutants of Rnf8 and Scml2 revealed that RNF8-dependent monoubiquitination of histone H2A at Lysine 119 (H2AK119ub) is deubiquitinated by SCML2, demonstrating interplay between RNF8 and SCML2 in ubiquitin regulation. Additionally, we identify distinct functions of RNF8 and SCML2 in the regulation of ubiquitination: SCML2 deubiquitinates RNF8-independent H2AK119ub but does not deubiquitinate RNF8 dependent polyubiquitination. RNF8-dependent polyubiquitination is required for the establishment of H3K27 acetylation, a marker of active enhancers, while persistent H2AK119ub inhibits establishment of H3K27 acetylation. Following the deposition of H3K27 acetylation, H3K4 dimethylation is established as an active mark on poised promoters. Together, we propose a model whereby regulation of ubiquitin leads to the organization of poised enhancers and promoters during meiosis, which induce subsequent gene activation from the otherwise silent sex chromosomes in postmeiotic spermatids. PMID- 29462144 TI - Perceptions on evaluative and formative functions of external supervision of Rwandan primary healthcare facilities: A qualitative study. AB - BACKGROUND: External supervision of primary healthcare facilities in low- and middle-income countries often has a managerial main purpose in which the role of support for professional development is unclear. AIM: To explore how Rwandan primary healthcare supervisors and providers (supervisees) perceive evaluative and formative functions of external supervision. DESIGN: Qualitative, exploratory study. DATA: Focus group discussions: three with supervisors, three with providers, and one mixed (n = 31). Findings were discussed with individual and groups of supervisors and providers. RESULTS: Evaluative activities occupied providers' understanding of supervision, including checking, correcting, marking and performance-based financing. These were presented as sources of motivation, that in self-determination theory indicate introjected regulation. Supervisors preferred to highlight their role in formative supervision, which may mask their own and providers' uncontested accounts that systematic performance evaluations predominated supervisors' work. Providers strongly requested larger focus on formative and supportive functions, voiced as well by most supervisors. Impact of performance evaluation on motivation and professional development is discussed. CONCLUSION: While external supervisors intended to support providers' professional development, our findings indicate serious problems with this in a context of frequent evaluations and performance marking. Separating the role of supporter and evaluator does not appear as the simple solution. If external supervision is to improve health care services, it is essential that supervisors and health centre managers are competent to support providers in a way that transparently accounts for various performance pressures. This includes delivery of proper formative supervision with useful feedback, maintaining an effective supervisory relationship, as well as ensuring providers are aware of the purpose and content of evaluative and formative supervision functions. PMID- 29462145 TI - Videourodynamic findings of lower urinary tract dysfunctions in men with persistent storage lower urinary tract symptoms after medical treatment. AB - OBJECTIVE: To analyze the underlying lower urinary tract dysfunctions by video urodynamic studies in men who have persistent storage symptoms after initial drug therapy for lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH). METHODS: The medical records of 614 men >=40 years of age with LUTS and an International Prostate Symptom Score of >=8 were retrospectively analyzed. All patients had persistent storage symptoms after medical treatment for at least 6 months. A video-urodynamic study was done to investigate the underlying bladder or bladder outlet dysfunction. Predictors of bladder outlet obstruction (BOO) by baseline urine flow metrics and prostate parameters were investigated. RESULTS: The final results revealed bladder neck dysfunction (BND) in 137/614 (22.3%), benign prostatic obstruction (BPO) in 246/614 (40.1%), detrusor overactivity (DO) in 193/614 (31.4%), and DO with detrusor underactivity (DO+DU) in 38/614 (6.2%) patients. Among the patients, 221/281 (78.6%) with a total prostatic volume (TPV) >=40 ml had BOO, including 43/281 (15.3%) with BND and 178/281 (63.3%) with BPO. If we combined TPV >=40 ml and Qmax <12 ml/s as predictors of BOO, BOO was found in 176/215 (81.8%) patients including 34/215 (15.8%) with BND and 142/215 (66.0%) with BPO. BOO was also found in 48.8% of men with a TPV <40ml, and in 36.3% of men with TPV< 40 ml and Qmax >= 12 ml/s. In 102 men with TPV <40 ml and Qmax >=12 ml/s, 64 (62.7%) had DO. CONCLUSION: BOO, including BND and BPO, comprise 62.4% (383/614) of men with persistent storage symptoms after initial medical treatment for LUTS/BPH. In men who have persistent storage symptoms after medical treatment for LUTS/BPH, BOO should be carefully investigated and appropriate management being given to improve LUTS. PMID- 29462146 TI - Prospective evaluation of accuracy and clinical utility of the Dual Path Platform (DPP) assay for the point-of-care diagnosis of leptospirosis in hospitalized patients. AB - Early detection of leptospirosis with field-ready diagnostics may improve clinical management and mitigate outbreaks. We previously validated the point-of care Dual Path Platform (DPP) for leptospirosis with sera in the laboratory. This prospective study compares the diagnostic accuracy and clinical utility of the DPP using finger stick blood (FSB) against the serum DPP, venous whole blood (VWB) DPP, IgM-ELISA, and clinical impression. We sequentially enrolled 98 patients hospitalized for acute febrile illnesses, of which we confirmed 32 by leptospirosis reference tests. Among syndromes consistent with classic leptospirosis, the FSB DPP showed similar sensitivity and specificity (Se 93% and Sp 80%), and positive and negative predictive values (PPV 74% and NPV 95%), to VWB DPP (Se 96%, Sp 75%, PPV 68%, and NPV 97%), serum DPP (Se 85%, Sp 87%, PPV 79%, and NPV 91%) and IgM-ELISA (Se 81%, Sp 100%, PPV 100%, and NPV 90%). The FSB DPP provided a favorable likelihood ratio profile (positive LR 4.73, negative LR 0.09) in comparison to other assays and clinical impression alone. Additionally, we identified four of five leptospirosis-associated meningitis patients by whole blood DPP, none of which clinicians suspected. This demonstrates potential for the DPP in routine detection of this less common syndrome. The FSB DPP demonstrated similar discrimination for severe human leptospirosis compared with serum assays, and it is a simpler option for diagnosing leptospirosis. Its performance in other epidemiological settings and geographic regions, and for detecting atypical presentations, demands further evaluation. PMID- 29462147 TI - Exploiting the geometry of the solution space to reduce sensitivity to neuromotor noise. AB - Throwing is a uniquely human skill that requires a high degree of coordination to successfully hit a target. Timing of ball release appears crucial as previous studies report required timing accuracies as short as 1-2ms, which however appear physiologically challenging. This study mathematically and experimentally demonstrates that humans can overcome these seemingly stringent timing requirements by shaping their hand trajectories to create extended timing windows, where ball releases achieve target hits despite temporal imprecision. Subjects practiced four task variations in a virtual environment, each with a distinct geometry of the solution space and different demands for timing. Model based analyses of arm trajectories revealed that subjects first decreased timing error, followed by lengthening timing windows in their hand trajectories. This pattern was invariant across solution spaces, except for a control case. Hence, the exquisite skill that humans evolved for throwing is achieved by developing strategies that are less sensitive to temporal variability arising from neuromotor noise. This analysis also provides an explanation why coaches emphasize the "follow-through" in many ball sports. PMID- 29462148 TI - Vocal development through morphological computation. AB - The vocal behavior of infants changes dramatically during early life. Whether or not such a change results from the growth of the body during development-as opposed to solely neural changes-has rarely been investigated. In this study of vocal development in marmoset monkeys, we tested the putative causal relationship between bodily growth and vocal development. During the first two months of life, the spontaneous vocalizations of marmosets undergo (1) a gradual disappearance of context-inappropriate call types and (2) an elongation in the duration of context appropriate contact calls. We hypothesized that both changes are the natural consequences of lung growth and do not require any changes at the neural level. To test this idea, we first present a central pattern generator model of marmoset vocal production to demonstrate that lung growth can affect the temporal and oscillatory dynamics of neural circuits via sensory feedback from the lungs. Lung growth qualitatively shifted vocal behavior in the direction observed in real marmoset monkey vocal development. We then empirically tested this hypothesis by placing the marmoset infants in a helium-oxygen (heliox) environment in which air is much lighter. This simulated a reversal in development by decreasing the effort required to respire, thus increasing the respiration rate (as though the lungs were smaller). The heliox manipulation increased the proportions of inappropriate call types and decreased the duration of contact calls, consistent with a brief reversal of vocal development. These results suggest that bodily growth alone can play a major role in shaping the development of vocal behavior. PMID- 29462149 TI - The INO80 chromatin remodeler sustains metabolic stability by promoting TOR signaling and regulating histone acetylation. AB - Chromatin remodeling complexes are essential for gene expression programs that coordinate cell function with metabolic status. However, how these remodelers are integrated in metabolic stability pathways is not well known. Here, we report an expansive genetic screen with chromatin remodelers and metabolic regulators in Saccharomyces cerevisiae. We found that, unlike the SWR1 remodeler, the INO80 chromatin remodeling complex is composed of multiple distinct functional subunit modules. We identified a strikingly divergent genetic signature for the Ies6 subunit module that links the INO80 complex to metabolic homeostasis. In particular, mitochondrial maintenance is disrupted in ies6 mutants. INO80 is also needed to communicate TORC1-mediated signaling to chromatin, as ino80 mutants exhibit defective transcriptional profiles and altered histone acetylation of TORC1-responsive genes. Furthermore, comparative analysis reveals subunits of INO80 and mTORC1 have high co-occurrence of alterations in human cancers. Collectively, these results demonstrate that the INO80 complex is a central component of metabolic homeostasis that influences histone acetylation and may contribute to disease when disrupted. PMID- 29462150 TI - Host plant forensics and olfactory-based detection in Afro-tropical mosquito disease vectors. AB - The global spread of vector-borne diseases remains a worrying public health threat, raising the need for development of new combat strategies for vector control. Knowledge of vector ecology can be exploited in this regard, including plant feeding; a critical resource that mosquitoes of both sexes rely on for survival and other metabolic processes. However, the identity of plant species mosquitoes feed on in nature remains largely unknown. By testing the hypothesis about selectivity in plant feeding, we employed a DNA-based approach targeting trnH-psbA and matK genes and identified host plants of field-collected Afro tropical mosquito vectors of dengue, Rift Valley fever and malaria being among the most important mosquito-borne diseases in East Africa. These included three plant species for Aedes aegypti (dengue), two for both Aedes mcintoshi and Aedes ochraceus (Rift Valley fever) and five for Anopheles gambiae (malaria). Since plant feeding is mediated by olfactory cues, we further sought to identify specific odor signatures that may modulate host plant location. Using coupled gas chromatography (GC)-electroantennographic detection, GC/mass spectrometry and electroantennogram analyses, we identified a total of 21 antennally-active components variably detected by Ae. aegypti, Ae. mcintoshi and An. gambiae from their respective host plants. Whereas Ae. aegypti predominantly detected benzenoids, Ae. mcintoshi detected mainly aldehydes while An. gambiae detected sesquiterpenes and alkenes. Interestingly, the monoterpenes beta-myrcene and (E) beta-ocimene were consistently detected by all the mosquito species and present in all the identified host plants, suggesting that they may serve as signature cues in plant location. This study highlights the utility of molecular approaches in identifying specific vector-plant associations, which can be exploited in maximizing control strategies such as such as attractive toxic sugar bait and odor-bait technology. PMID- 29462151 TI - The self-organization of plant microtubules inside the cell volume yields their cortical localization, stable alignment, and sensitivity to external cues. AB - Many cell functions rely on the ability of microtubules to self-organize as complex networks. In plants, cortical microtubules are essential to determine cell shape as they guide the deposition of cellulose microfibrils, and thus control mechanical anisotropy of the cell wall. Here we analyze how, in turn, cell shape may influence microtubule behavior. Building upon previous models that confined microtubules to the cell surface, we introduce an agent model of microtubules enclosed in a three-dimensional volume. We show that the microtubule network has spontaneous aligned configurations that could explain many experimental observations without resorting to specific regulation. In particular, we find that the preferred cortical localization of microtubules emerges from directional persistence of the microtubules, and their interactions with each other and with the stiff wall. We also identify microtubule parameters that seem relatively insensitive to cell shape, such as length or number. In contrast, microtubule array anisotropy depends on local curvature of the cell surface and global orientation follows robustly the longest axis of the cell. Lastly, we find that geometric cues may be overcome, as the network is capable of reorienting toward weak external directional cues. Altogether our simulations show that the microtubule network is a good transducer of weak external polarity, while at the same time, easily reaching stable global configurations.

AB - BACKGROUND: Sierra Leone has one of the highest maternal mortality ratios in the world. Efforts to reduce maternal mortality have included initiatives to encourage more women to deliver at health facilities. Despite the introduction of the free health care initiative for pregnant women, many women still continue to deliver at home, with few having access to a skilled birth attendant. In addition, inequalities between rural and urban areas in accessing and utilising health facilities persist. Further insight into how and why women make decisions around childbirth will help guide future plans and initiatives in improving maternal health in Sierra Leone. The objective of this study was to explore the perceptions and decision-making processes of women and their communities during childbirth in rural Sierra Leone. METHODS AND FINDINGS: Data were collected through seven focus group discussions and 22 in-depth interviews with recently pregnant women and their community members in two rural villages. Data were analysed using systematic text condensation. Findings revealed that decision making processes during childbirth are dynamic, intricate and need to be understood within the broader social context that they take place. Factors such as distance and lack of transport, perceived negative behaviour of hospital staff, direct and indirect financial obstacles, as well as the position of women in society all interact and influence how and what decisions are made. CONCLUSIONS: Pregnant women face multiple interacting vulnerabilities that influence their healthcare-seeking decisions during pregnancy and childbirth. Future initiatives to improve access and utilisation of safe healthcare services for pregnant women need to be based on adequate knowledge of structural constraints and health inequities that affect women in rural Sierra Leone. PMID- 29462153 TI - Design of synthetic bacterial communities for predictable plant phenotypes. AB - Specific members of complex microbiota can influence host phenotypes, depending on both the abiotic environment and the presence of other microorganisms. Therefore, it is challenging to define bacterial combinations that have predictable host phenotypic outputs. We demonstrate that plant-bacterium binary association assays inform the design of small synthetic communities with predictable phenotypes in the host. Specifically, we constructed synthetic communities that modified phosphate accumulation in the shoot and induced phosphate starvation-responsive genes in a predictable fashion. We found that bacterial colonization of the plant is not a predictor of the plant phenotypes we analyzed. Finally, we demonstrated that characterizing a subset of all possible bacterial synthetic communities is sufficient to predict the outcome of untested bacterial consortia. Our results demonstrate that it is possible to infer causal relationships between microbiota membership and host phenotypes and to use these inferences to rationally design novel communities. PMID- 29462154 TI - Functional characterization and genomic studies of a novel murine submandibular gland epithelial cell line. AB - A better understanding of the normal and diseased biology of salivary glands (SG) has been hampered, in part, due to difficulties in cultivating and maintaining salivary epithelial cells. Towards this end, we have generated a mouse salivary gland epithelial cell (mSGc) culture system that is well-suited for the molecular characterization of SG cells and their differentiation program. We demonstrate that mSGc can be maintained for multiple passages without a loss of proliferation potential, readily form 3D-spheroids and importantly express a panel of well established salivary gland epithelial cell markers. Moreover, mSGc 3D-spheroids also exhibit functional maturation as evident by robust agonist-induced intracellular calcium signaling. Finally, transcriptomic characterization of mSGc by RNA-seq and hierarchical clustering analysis with adult organ RNA-seq datasets reveal that mSGc retain most of the molecular attributes of adult mouse salivary gland. This well-characterized mouse salivary gland cell line will fill a critical void in the field by offering a valuable resource to examine various mechanistic aspects of mouse salivary gland biology. PMID- 29462155 TI - Rifampicin versus streptomycin for brucellosis treatment in humans: A meta analysis of randomized controlled trials. AB - Brucellosis is a zoonotic disease with a high morbidity in developing countries, but there the optimal treatment is not yet determined. Therefore, the development of a simple and effective treatment is important. The aim of this study was to summarize the available evidences and compare rifampicin with streptomycin in human brucellosis with doxycycline as background regimen. We systematically searched PubMed, EmBase, and the Cochrane Library from their inception up through December 2016. We included studies with a randomized controlled design that evaluated the effect of streptomycin compared with rifampicin in human brucellosis patients who received doxycycline therapy as background regimen. The overall failure and relapse were summarized using random-effects model. Our meta analysis included 1,383 patients with brucellosis from 14 trials. We found that patients who received rifampicin therapy had a higher risk of overall failure (RR: 2.36; 95% CI: 1.72-3.23; P<0.001) and relapse (RR: 2.74; 95% CI: 1.80-4.19; P<0.001) compared with streptomycin. Results of the sensitivity analysis were consistent with the overall analysis. Subgroup analysis indicated that mean age of the patients and percentage of male participants might influence the treatment effects. Furthermore, no publication bias was detected. The findings of this study indicated that rifampicin therapy significantly increased the risk of overall failure and relapse compared with streptomycin. Hence, it can be recommended to patients with human brucellosis receiving streptomycin therapy. PMID- 29462156 TI - Preferences for HIV test characteristics among young, Black Men Who Have Sex With Men (MSM) and transgender women: Implications for consistent HIV testing. AB - BACKGROUND: Promoting consistent HIV testing is critical among young, Black Men Who Have Sex With Men (MSM) and transgender women who are overrepresented among new HIV cases in the United States. New HIV test options are available, including mobile unit testing, one-minute testing, at home or self-testing and couples HIV testing and counseling (CHTC). In the context of these newer options, the objective of this study was to explore whether and how preferences for specific characteristics of the tests acted as barriers to and/or facilitators of testing in general and consistent testing specifically among young Black MSM and transgender women aged 16 to 29. METHODS: We conducted 30 qualitative, semi structured, in-depth interviews with young, Black, gay, bisexual or MSM and transgender women in the New York City metropolitan area to identify preferences for specific HIV tests and aspects of HIV testing options. Participants were primarily recruited from online and mobile sites, followed by community-based, face-to-face recruitment strategies to specifically reach younger participants. Thematic coding was utilized to analyze the qualitative data based on a grounded theoretical approach. RESULTS: We identified how past experiences, perceived test characteristics (e.g., accuracy, cost, etc.) and beliefs about the "fit" between the individual, and the test relate to preferred testing methods and consistent testing. Three major themes emerged as important to preferences for HIV testing methods: the perceived accuracy of the test method, venue characteristics, and lack of knowledge or experience with the newer testing options, including self testing and CHTC. CONCLUSIONS: These findings suggest that increasing awareness of and access to newer HIV testing options (e.g., free or reduced price on home or self-tests or CHTC available at all testing venues) is critical if these new options are to facilitate increased levels of consistent testing among young, Black MSM and transgender women. Addressing perceptions of test accuracy and supporting front line staff in creating welcoming and safe testing environments may be key intervention targets. Connecting young Black MSM and transgender women to the best test option, given preferences for specific characteristics, may support more and more consistent HIV testing. PMID- 29462157 TI - A mouse model study of toxicity and biodistribution of a replication defective adenovirus serotype 5 virus with its genome engineered to contain a decoy hyper binding site to sequester and suppress oncogenic HMGA1 as a new cancer treatment therapy. AB - The HGMA1 architectural transcription factor is highly overexpressed in many human cancers. Because HMGA1 is a hub for regulation of many oncogenes, its overexpression in cancer plays a central role in cancer progression and therefore HMGA1 is gaining increasing attention as a target for development of therapeutic approaches to suppress either its expression or action in cancer cells. We have developed the strategy of introducing decoy hyper binding sites for HMGA1 into the nucleus of cancer cells with the goal of competetively sequestering overexpressed HMGA1 and thus suppressing its oncogenic action. Towards achieving this goal, we have introduced an HMGA1 decoy hyper binding site composed of six copies of a high affinity HMGA1 binding site into the genome of the replication defective adenovirus serotype 5 genome and shown that the engineered virus effectively reduces the viability of human pancreatic and cancer cells. Here we report the first pre-clinical measures of toxicity and biodistribution of the engineered virus in C57BL/6J Black 6 mice. The immune response to exposure of the engineered virus was determined by assaying the serum levels of key cytokines, IL 6 and TNF-alpha. Toxicity due to exposure to the virus was determined by measuring the serum levels of the liver enzymes aspartate aminotransferase and alanine aminotransferase. Biodistribution was measured following direct injection into the pancreas or liver by quantifying viral loads in the pancreas, liver, spleen and brain. PMID- 29462158 TI - Docosahexaenoic acid for reading, working memory and behavior in UK children aged 7-9: A randomized controlled trial for replication (the DOLAB II study). AB - BACKGROUND: Omega-3 fatty acids are central to brain-development of children. Evidence from clinical trials and systematic reviews demonstrates the potential of long-chain Omega-3 supplementation for learning and behavior. However, findings are inconclusive and in need of robust replication studies since such work is lacking. OBJECTIVES: Replication of the 2012 DOLAB 1 study findings that a dietary supplementation with the long-chain omega-3 docosahexaenoic acid (DHA) had beneficial effects on the reading, working memory, and behavior of healthy schoolchildren. DESIGN: Parallel group, fixed-dose, randomized (minimization, 30% random element), double-blind, placebo-controlled trial (RCT). SETTING: Mainstream primary schools (n = 84) from five counties in the UK in 2012-2015. PARTICIPANTS: Healthy children aged 7-9 underperforming in reading (<20th centile). 1230 invited, 376 met study criteria. INTERVENTION: 600 mg/day DHA (from algal oil), placebo: taste/color matched corn/soybean oil; for 16 weeks. MAIN OUTCOME MEASURES: Age-standardized measures of reading, working memory, and behavior, parent-rated and as secondary outcome teacher-rated. RESULTS: 376 children were randomized. Reading, working memory, and behavior change scores showed no consistent differences between intervention and placebo group. Some behavioral subscales showed minor group differences. CONCLUSIONS: This RCT did not replicate results of the earlier DOLAB 1 study on the effectiveness of nutritional supplementation with DHA for learning and behavior. Possible reasons are discussed, particularly regarding the replication of complex interventions.

PMID- 29462159 TI - Factors associated with occasional and recurrent falls in Mexican community dwelling older people. AB - Falls are a frequent event among older adults that can cause wounds, disability, psychological disorders, and premature death. Although the large number of existing studies on the issue, few have been conducted in middle- and low-income countries. The objective of the present study is to identify the sociodemographic, medical, and functional performance factors associated with occasional and recurrent falls in Mexican older adults dwelling in community. Cross-sectional analysis of 9 598 adults >=60 years old who participated in the fourth round (2015) of the Mexican Health and Aging Study. Bivariate tests were performed to evaluate the differences between covariates by distinct fall groups (no falls, occasional falls, and recurrent falls). Multiple logistic regressions with unadjusted and adjusted models were estimated. Approximately 46% of older adults had had at least one fall during the previous two years (one fall 16% and recurrent falls 30%). Occasional falls were only associated with being a woman; in addition to the sex, recurrent falls were strongly associated with advanced age, rural residence, bad and very bad self-perception of health status, activity limiting pain, urinary incontinence, depression, arthritis, limitations in basic activities of daily living, and limitations in advanced activities of daily living. Falls, primarily recurrent falls, deserve to be addressed through multifactorial strategies that include different areas of intervention. PMID- 29462160 TI - Identifying potential maternal genes of Bombyx mori using digital gene expression profiling. AB - Maternal genes present in mature oocytes play a crucial role in the early development of silkworm. Although maternal genes have been widely studied in many other species, there has been limited research in Bombyx mori. High-throughput next generation sequencing provides a practical method for gene discovery on a genome-wide level. Herein, a transcriptome study was used to identify maternal related genes from silkworm eggs. Unfertilized eggs from five different stages of early development were used to detect the changing situation of gene expression. The expressed genes showed different patterns over time. Seventy-six maternal genes were annotated according to homology analysis with Drosophila melanogaster. More than half of the differentially expressed maternal genes fell into four expression patterns, while the expression patterns showed a downward trend over time. The functional annotation of these material genes was mainly related to transcription factor activity, growth factor activity, nucleic acid binding, RNA binding, ATP binding, and ion binding. Additionally, twenty-two gene clusters including maternal genes were identified from 18 scaffolds. Altogether, we plotted a profile for the maternal genes of Bombyx mori using a digital gene expression profiling method. This will provide the basis for maternal-specific signature research and improve the understanding of the early development of silkworm. PMID- 29462161 TI - Lipoproteins comprise at least 10 different classes in rats, each of which contains a unique set of proteins as the primary component. AB - Although lipoproteins are conventionally separated into a few classes using density gradient centrifugation, there may be a much higher number of physical classes that differ in origin or phase. Comprehensive knowledge of the classes of lipoproteins is rather limited, which hinders both the study of their functions and the identification of the primary causes of related diseases. This study aims to determine the number of classes of lipoproteins that can be practically distinguishable and identify the differences between them. We separated rat serum samples by gel filtration. The elution was continuously monitored for triglyceride (TG), cholesterol, and protein, and fractionated for further SDS PAGE and immunological detection of apoprotein A-I (ApoA1) and apoprotein B (ApoB). The elution patterns were analyzed using a parsimonious method, i.e., the estimation of the least number of classes. Ten classes were recognized that contained different amounts of TG and cholesterol, as well as a unique protein content. Each of the classes contained much more protein than that observed previously, especially in low-density lipoproteins (LDL) classes. In particular, two major antiproteases formed complexes with specific classes of LDL; because these classes exclusively carry cholesterol and antiproteases, they may lead to the progression of atheroma by supplying materials that enlarge fatty streaks and protecting thrombi from enzymatic digestion. The separated classes may have specific biological functions. The attribution of protein species to certain classes will help understand the functions. A distinction among lipoprotein classes may provide important information in the field of vascular pathology. PMID- 29462162 TI - Vasomotor and physical menopausal symptoms are associated with sleep quality. AB - BACKGROUND: Sleep disturbance is one of the common complaints in menopause. This study investigated the relationship between menopausal symptoms and sleep quality in middle-aged women. METHOD: This cross-sectional observational study involved 634 women aged 44-56 years attending a healthcare center at Kangbuk Samsung Hospitals. Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI).Multiple linear regression analysis was performed to assess the associations between Menopause-specific Quality of Life (MENQOL) scores and PSQI scores and Menopause-specific Quality of Life (MENQOL)scores. RESULTS: The mean PSQI score was 3.6+/-2.3, and the rates of poor sleep quality(PSQI score > 5) in premenopausal, perimenopausal, and postmenopausal women were 14.4%, 18.2%, and 30.2%, respectively. Total PSQI score, specifically the sleep latency, habitual sleep efficiency and sleep disturbances scores, were significantly increased in postmenopausal women. Multiple linear regression analysis adjusted for age, BMI, hypertension, diabetes, smoking, marital status, family income, education, employment status, parity, physical activity, depression symptoms, perceived stress and menopausal status showed that higher PSQI score was positively correlated with higher vasomotor(beta = 0.240, P = 0.020)and physical(beta = 0.572, P<0.001) scores. CONCLUSIONS: Vasomotor and physical menopause symptoms was related to poor sleep quality. Effective management strategies aimed at reducing menopausal symptoms may improve sleep quality among women around the time of menopause. PMID- 29462163 TI - Social-emotional competence and early adolescents' peer acceptance in school: Examining the role of afternoon cortisol. AB - The present study investigated the role of afternoon cortisol in social-emotional competence and peer acceptance in early adolescence. To date, research on basal cortisol activity and social development in childhood and adolescence has predominately focused on understanding maladjustment and dysfunction in development. The degree to which basal cortisol is also involved in positive adjustment and social functioning remains largely unexplored. A total of 154 early adolescents (46% female; Mean age = 11.26; SD = .65) from diverse ethnic backgrounds provided self-reports of perspective taking, peer reports of acceptance by classmates, peer reports of prosocial behaviors, and saliva samples to assess basal cortisol. As expected and in alignment with previous research, afternoon cortisol, perspective taking, prosocial behaviors, and peer acceptance were all positively correlated. Path analyses followed by bootstrapping analyses revealed that the direct path from higher afternoon cortisol to higher levels of prosocial behavior was fully mediated by perspective taking skills. The direct path from higher afternoon cortisol to peer acceptance was fully mediated by perspective taking skills and prosocial behavior. The findings are discussed within the broader context of previous research on cortisol and social adjustment in childhood and early adolescence. The practical relevance of the findings is considered. PMID- 29462164 TI - Phylogeography and DNA-based species delimitation provide insight into the taxonomy of the polymorphic rose chafer Protaetia (Potosia) cuprea species complex (Coleoptera: Scarabaeidae: Cetoniinae) in the Western Palearctic. AB - The development of modern methods of species delimitation, unified under the "integrated taxonomy" approach, allows a critical examination and re-evaluation of complex taxonomic groups. The rose chafer Protaetia (Potosia) cuprea is a highly polymorphic species group with a large distribution range. Despite its overall commonness, its taxonomy is unclear and subject to conflicting hypotheses, most of which largely fail to account for its evolutionary history. Based on the sequences of two mitochondrial markers from 65 individuals collected across the species range, and a detailed analysis of morphological characters including a geometric morphometry approach, we infer the evolutionary history and phylogeography of the P. cuprea species complex. Our results demonstrate the existence of three separate lineages in the Western Palearctic region, presumably with a species status. However, these lineages are in conflict with current taxonomic concepts. None of the 29 analyzed morphological characters commonly used in the taxonomy of this group proved to be unambiguously species- or subspecies- specific. The geometric morphometry analysis reveals a large overlap in the shape of the analyzed structures (pronotum, meso-metaventral projection, elytra and aedeagus), failing to identify either the genetically detected clades or the classical species entities. Our results question the monophyly of P. cuprea in regard to P. cuprina, as well as the species status of P. metallica. On the other hand, we found support for the species status of the Sicilian P. hypocrita. Collectively, our findings provide a new and original insight into the taxonomy and phylogeny of the P. cuprea species complex. At the same time, the results represent the first attempt to elucidate the phylogeography of these polymorphic beetles. PMID- 29462165 TI - Thromboelastometry profile in critically ill patients: A single-center, retrospective, observational study. AB - BACKGROUND: Transfusion therapy is associated with increased morbidity, mortality and costs. Conventional coagulation tests (CCT) are weak bleeding predictors, poorly reflecting coagulation in vivo. Thromboelastometry (ROTEM) provides early identification of coagulation disorders and can guide transfusion therapy by goals, reducing blood components transfusion. OBJECTIVE: The aim of this study is to describe coagulation profile of critically ill patients using ROTEM and evaluate the association between CCT and thromboelastometry. METHODS: This is a retrospective, observational study conducted in medical-surgical intensive care unit (ICU). Adult patients (>=18 years) admitted to ICU between November 2012 and December 2014, in whom ROTEM analyses were performed for bleeding management were included in this study. The first ROTEM and CCT after ICU admission were recorded simultaneously. Additionally, we collected data on blood components transfusion and hemostatic agents immediately after laboratory tests results. RESULTS: The study included 531 patients. Most ROTEM tests showed normal coagulation profile [INTEM (54.8%), EXTEM (54.1%) and FIBTEM (53.3%)] with divergent results in relation to CCT: low platelet count (51.8% in INTEM and 55.9% in EXTEM); prolonged aPTT (69.9% in INTEM and 63.7% in EXTEM) and higher INR (23.8% in INTEM and 27.4% in EXTEM). However 16,7% of patients with normocoagulability in ROTEM received platelet concentrates and 10% fresh frozen plasma. CONCLUSION: The predominant ROTEM profile observed in this sample of critically ill patients was normal. In contrast, CCT suggested coagulopathy leading to a possibly unnecessary allogenic blood component transfusion. ROTEM test may avoid inappropriate allogeneic blood products transfusion in these patients. PMID- 29462166 TI - Oncologic emergencies in a cancer center emergency department and in general emergency departments countywide and nationwide. AB - BACKGROUND: Although cancer patients (CPs) are increasingly likely to visit emergency department (ED), no population-based study has compared the characteristics of CPs and non-cancer patients (NCPs) who visit the ED and examined factors associated with hospitalization via the ED. In this study, we (1) compared characteristics and diagnoses between CPs and NCPs who visited the ED in a cancer center or general hospital; (2) compared characteristics and diagnoses between CPs and NCPs who were hospitalized via the ED in a cancer center or general hospital; and (3) investigated important factors associated with such hospitalization. METHODS AND FINDINGS: We analyzed patient characteristic and diagnosis [based on International Classification of Diseases-9 (ICD-9) codes] data from the ED of a comprehensive cancer center (MDACC), 24 general EDs in Harris County, Texas (HCED), and the National Hospital Ambulatory Medical Care Survey (NHAMCS) from 1/1/2007-12/31/2009. Approximately 3.4 million ED visits were analyzed: 47,245, 3,248,973, and 104,566 visits for MDACC, HCED, and NHAMCS, respectively, of which 44,143 (93.4%), 44,583 (1.4%), and 632 (0.6%) were CP visits. CPs were older than NCPs and stayed longer in EDs. Lung, gastrointestinal (excluding colorectal), and genitourinary (excluding prostate) cancers were the three most common diagnoses related to ED visits at general EDs. CPs visiting MDACC were more likely than CPs visiting HCED to be privately insured. CPs were more likely than NCPs to be hospitalized. Pneumonia and influenza, fluid and electrolyte disorders, and fever were important predictive factors for CP hospitalization; coronary artery disease, cerebrovascular disease, and heart failure were important factors for NCP hospitalization. CONCLUSIONS: CPs consumed more ED resources than NCPs and had a higher hospitalization rate. Given the differences in characteristics and diagnoses between CPs and NCPs, ED physicians must pay special attention to CPs and be familiar with their unique set of oncologic emergencies. PMID- 29462167 TI - Prediction of infectious disease epidemics via weighted density ensembles. AB - Accurate and reliable predictions of infectious disease dynamics can be valuable to public health organizations that plan interventions to decrease or prevent disease transmission. A great variety of models have been developed for this task, using different model structures, covariates, and targets for prediction. Experience has shown that the performance of these models varies; some tend to do better or worse in different seasons or at different points within a season. Ensemble methods combine multiple models to obtain a single prediction that leverages the strengths of each model. We considered a range of ensemble methods that each form a predictive density for a target of interest as a weighted sum of the predictive densities from component models. In the simplest case, equal weight is assigned to each component model; in the most complex case, the weights vary with the region, prediction target, week of the season when the predictions are made, a measure of component model uncertainty, and recent observations of disease incidence. We applied these methods to predict measures of influenza season timing and severity in the United States, both at the national and regional levels, using three component models. We trained the models on retrospective predictions from 14 seasons (1997/1998-2010/2011) and evaluated each model's prospective, out-of-sample performance in the five subsequent influenza seasons. In this test phase, the ensemble methods showed average performance that was similar to the best of the component models, but offered more consistent performance across seasons than the component models. Ensemble methods offer the potential to deliver more reliable predictions to public health decision makers. PMID- 29462168 TI - Risk and surrogate benefit for pediatric Phase I trials in oncology: A systematic review with meta-analysis. AB - BACKGROUND: Pediatric Phase I cancer trials are critical for establishing the safety and dosing of anti-cancer treatments in children. Their implementation, however, must contend with the rarity of many pediatric cancers and limits on allowable risk in minors. The aim of this study is to describe the risk and benefit for pediatric cancer Phase I trials. METHODS AND FINDINGS: Our protocol was prospectively registered in PROSPERO (CRD42015015961). We systematically searched Embase and PubMed for solid and hematological malignancy Phase I pediatric trials published between 1 January 2004 and 1 March 2015. We included pediatric cancer Phase I studies, defined as "small sample size, non-randomized, dose escalation studies that defined the recommended dose for subsequent study of a new drug in each schedule tested." We measured risk using grade 3, 4, and 5 (fatal) drug-related adverse events (AEs) and benefit using objective response rates. When possible, data were meta-analyzed. We identified 170 studies meeting our eligibility criteria, accounting for 4,604 patients. The pooled overall objective response rate was 10.29% (95% CI 8.33% to 12.25%), and was lower in solid tumors, 3.17% (95% CI 2.62% to 3.72%), compared with hematological malignancies, 27.90% (95% CI 20.53% to 35.27%); p < 0.001. The overall fatal (grade 5) AE rate was 2.09% (95% CI 1.45% to 2.72%). Across the 4,604 evaluated patients, there were 4,675 grade 3 and 4 drug-related AEs, with an average grade 3/4 AE rate per person equal to 1.32. Our study had the following limitations: trials included in our review were heterogeneous (to minimize heterogeneity, we separated types of therapy and cancer types), and we relied on published data only and encountered challenges with the quality of reporting. CONCLUSIONS: Our meta-analysis suggests that, on the whole, AE and response rates in pediatric Phase I trials are similar to those in adult Phase I trials. Our findings provide an empirical basis for the refinement and review of pediatric Phase I trials, and for communication about their risk and benefit. PMID- 29462169 TI - Characteristics and predictors for gastrointestinal hemorrhage among adult patients with dengue virus infection: Emphasizing the impact of existing comorbid disease(s). AB - BACKGROUND: Gastrointestinal (GI) bleeding is a leading cause of death in dengue. This study aims to identify predictors for GI bleeding in adult dengue patients, emphasizing the impact of existing comorbid disease(s). METHODS: Of 1300 adults with dengue virus infection, 175 (mean age, 56.5+/-13.7 years) patients with GI bleeding and 1,125 (mean age, 49.2+/-15.6 years) without GI bleeding (controls) were retrospectively analyzed. RESULTS: Among 175 patients with GI bleeding, dengue hemorrhagic fever was found in 119 (68%) patients; the median duration from onset dengue illness to GI bleeding was 5 days. Gastric ulcer, erythematous gastritis, duodenal ulcer, erosive gastritis, and hemorrhagic gastritis were found in 52.3%, 33.3%, 28.6%, 28.6%, and 14.3% of 42 patients with GI bleeding who had undergone endoscopic examination, respectively. Overall, nine of the 175 patients with GI bleeding died, giving an in-hospital mortality rate of 5.1%. Multivariate analysis showed age >=60 years (cases vs. controls: 48% vs. 28.3%) (odds ratio [OR]: 1.663, 95% confidence interval [CI]: 1.128-2.453), end stage renal disease with additional comorbidities (cases vs. controls: 1.7% vs. 0.2%) (OR: 9.405, 95% CI: 1.4-63.198), previous stroke with additional comorbidities (cases vs. controls: 7.4% vs. 0.6%) (OR: 9.772, 95% CI: 3.302-28.918), gum bleeding (cases vs. controls: 27.4% vs. 11.5%) (OR: 1.732, 95% CI: 1.1-2.727), petechiae (cases vs. controls: 56.6% vs. 29.1%) (OR: 2.109, 95% CI: 1.411-3.153), and platelet count <50*109 cells/L (cases vs. controls: 53.1% vs. 25.8%) (OR: 3.419, 95% CI: 2.103-5.558) were independent predictors of GI bleeding in patients with dengue virus infection. CONCLUSIONS: Our study is the first to disclose that end stage renal disease and previous stroke, with additional comorbidities, were strongly significant associated with the risk of GI bleeding in patients with dengue virus infection. Identification of these risk factors can be incorporated into the patient assessment and management protocol of dengue virus infection to reduce its mortality. PMID- 29462170 TI - Mitochondrial DNA variants of Podolian cattle breeds testify for a dual maternal origin. AB - BACKGROUND: Over the past 15 years, 300 out of 6000 breeds of all farm animal species identified by the Food and Agriculture Organization of the United Nations (FAO) have gone extinct. Among cattle, many Podolian breeds are seriously endangered in various European areas. Podolian cattle include a group of very ancient European breeds, phenotypically close to the aurochs ancestors (Bos primigenius). The aim of the present study was to assess the genetic diversity of Podolian breeds and to reconstruct their origin. METHODOLOGY: The mitochondrial DNA (mtDNA) control-regions of 18 Podolian breeds have been phylogenetically assessed. Nine non-Podolian breeds have been also included for comparison. CONCLUSION: The overall analysis clearly highlights some peculiarities in the mtDNA gene pool of some Podolian breeds. In particular, a principal component analysis point to a genetic proximity between five breeds (Chianina, Marchigiana, Maremmana, Podolica Italiana and Romagnola) reared in Central Italy and the Turkish Grey. We here propose the suggestive hypothesis of a dual ancestral contribution to the present gene pool of Podolian breeds, one deriving from Eastern European cattle; the other arising from the arrival of Middle Eastern cattle into Central Italy through a different route, perhaps by sea, ferried by Etruscan boats. The historical migration of Podolian cattle from North Eastern Europe towards Italy has not cancelled the mtDNA footprints of this previous ancient migration. PMID- 29462171 TI - Stigma gets in my way: Factors affecting client-provider communication regarding childbearing among people living with HIV in Uganda. AB - INTRODUCTION: Many HIV-affected couples living in sub-Saharan Africa desire to have children, but few quantitative studies have examined support for their childbearing needs. Our study explored client-provider communication about childbearing and safer conception among HIV clients in Uganda. METHODS: 400 Ugandan HIV clients in committed relationships and with intentions to conceive were surveyed. Knowledge, attitudes and practices related to childbearing, and use of safer conception methods were assessed, including communication with providers about childbearing needs, the correlates of which were examined with bivariate statistics and logistic multivariate analysis. RESULTS: 75% of the sample was female; 61% were on antiretroviral therapy; and 61% had HIV-negative or unknown status partners. Nearly all (98%) reported the desire to discuss childbearing intentions with their HIV provider; however, only 44% reported such discussions, the minority (28%) of which was initiated by the provider. Issues discussed with HIV providers included: HIV transmission risk to partner (30%), HIV transmission risk to child (30%), and how to prevent transmission to the child (27%); only 8% discussed safer conception methods. Regression analysis showed that those who had communicated with providers about childbearing were more likely to have been diagnosed with HIV for a longer period [OR (95% CI) = 1.09 (1.03, 1.15)], while greater internalized childbearing stigma was associated with lower odds of this communication [OR (95% CI) = 0.70 (0.49, 0.99)], after controlling for all bivariate correlates and basic demographics. CONCLUSIONS: Communication between HIV clients and providers about childbearing needs is poor and associated with stigma. Innovations to mitigate stigma among clients as well as training to improve health worker communication and skills related to safer conception counseling is needed. PMID- 29462172 TI - Hemostatic findings of pleural fluid in dogs and the association between pleural effusions and primary hyperfibrino(geno)lysis: A cohort study of 99 dogs. AB - The primary objective of this study was to determine if activation of coagulation and fibrinolysis occurs in canine pleural effusions. Thirty-three dogs with pleural effusions of different origin were studied. Pleural effusion fibrinogen concentrations were significantly lower, while pleural fibrin-fibrinogen degradation products (FDPs) and D-dimer concentrations were significantly higher than those in plasma (P < 0.001 for all comparisons). These results show that, in canine pleural fluids, there is evidence of coagulation activation and fibrinolysis. The secondary aims of the current study were to determine if primary hyperfibrinolysis ([PHF] i.e., elevated plasma FDPs with a normal D-dimer concentrations), occurs in dogs with pleural effusion, and whether the presence of a concurrent inflammatory process may have activated the hemostatic cascade, with its intrinsically linked secondary hyperfibrinolysis, masking the concurrent PHF. The previously 33 selected dogs with pleural effusion (group 1) were compared to two control groups of 33 healthy (group 2) and 33 sick dogs without pleural effusion (group 3). Serum fibrinogen, FDPs, D-dimer, C-reactive protein (CRP), fibrinogen/CRP ratio, and frequency of PHF were determined. Fibrinogen, FDPs, D-dimer and CRP concentrations in group 1 were significantly increased compared to group 2 (P < 0.001 for all comparisons). FDPs and CRP concentrations in group 1 were also significantly increased compared to group 3 (P = 0.001 and P < 0.001, respectively). The fibrinogen/CRP ratio was significantly decreased in group 1 compared to groups 2 and 3 (P < 0.001 for both comparison). The frequency of PHF was significantly higher in group 1 compared to groups 2 (P = 0.004), but not compared to group 3. These results support the hypothesis that PHF occurs significantly more often in dogs with pleural effusion compared to healthy dogs. Nevertheless, the decrease in the fibrinogen/CRP ratio in group 1 compared to group 3, considering the higher FDPs and similar D-dimer concentrations, would suggest that PHF is also more frequent in dogs with pleural effusion compared to sick control dogs, and that this phenomenon is hidden due to concurrent secondary hyperfibrinolysis. PMID- 29462173 TI - Imaging cellular pharmacokinetics of 18F-FDG and 6-NBDG uptake by inflammatory and stem cells. AB - OBJECTIVES: Myocardial infarction (MI) causes significant loss of cardiomyocytes, myocardial tissue damage, and impairment of myocardial function. The inability of cardiomyocytes to proliferate prevents the heart from self-regeneration. The treatment for advanced heart failure following an MI is heart transplantation despite the limited availability of the organs. Thus, stem-cell-based cardiac therapies could ultimately prevent heart failure by repairing injured myocardium that reverses cardiomyocyte loss. However, stem-cell-based therapies lack understanding of the mechanisms behind a successful therapy, including difficulty tracking stem cells to provide information on cell migration, proliferation and differentiation. In this study, we have investigated the interaction between different types of stem and inflammatory cells and cell-targeted imaging molecules, 18F-FDG and 6-NBDG, to identify uptake patterns and pharmacokinetics in vitro. METHODS: Macrophages (both M1 and M2), human induced pluripotent stem cells (hiPSCs), and human amniotic mesenchymal stem cells (hAMSCs) were incubated with either 18F-FDG or 6-NBDG. Excess radiotracer and fluorescence were removed and a 100 MUm-thin CdWO4 scintillator plate was placed on top of the cells for radioluminescence microscopy imaging of 18F-FDG uptake, while no scintillator was needed for fluorescence imaging of 6-NBDG uptake. Light produced following beta decay was imaged with a highly sensitive inverted microscope (LV200, Olympus) and an Electron Multiplying Charge-Couple Device (EM-CCD) camera. Custom-written software was developed in MATLAB for image processing. RESULTS: The average cellular activity of 18F-FDG in a single cell of hAMSCs (0.670+/-0.028 fCi/MUm2, P = 0.001) was 20% and 36% higher compared to uptake in hiPSCs (0.540+/-0.026 fCi/MUm2, P = 0.003) and macrophages (0.430+/-0.023 fCi/MUm2, P = 0.002), respectively. hAMSCs exhibited the slowest influx (0.210 min-1) but the fastest efflux (0.327 min-1) rate compared to the other tested cell lines for 18F-FDG. This cell line also has the highest phosphorylation but exhibited the lowest rate of de-phosphorylation. The uptake pattern for 6-NBDG was very different in these three cell lines. The average cellular activity of 6-NBDG in a single cell of macrophages (0.570+/-0.230 fM/MUm2, P = 0.004) was 38% and 14% higher compared to hiPSCs (0.350+/-0.160 fM/MUm2, P = 0.001) and hAMSCs (0.490+/-0.028 fM/MUm2, P = 0.006), respectively. The influx (0.276 min-1), efflux (0.612 min-1), phosphorylation (0.269 min-1), and de-phosphorylation (0.049 min-1) rates were also highest for macrophages compared to the other two tested cell lines. CONCLUSION: hAMSCs were found to be 2-3* more sensitive to 18F-FDG molecule compared to hiPSCs/macrophages. However, macrophages exhibited the most sensitivity towards 6-NBDG. Based on this result, hAMSCs targeted with 18F-FDG could be more suitable for understanding the mechanisms behind successful therapy for treating MI patients by gathering information on cell migration, proliferation and differentiation. PMID- 29462174 TI - Exposure to 1.8 GHz electromagnetic fields affects morphology, DNA-related Raman spectra and mitochondrial functions in human lympho-monocytes. AB - Blood is a fluid connective tissue of human body, where it plays vital functions for the nutrition, defense and well-being of the organism. When circulating in peripheral districts, it is exposed to some physical stresses coming from outside the human body, as electromagnetic fields (EMFs) which can cross the skin. Such fields may interact with biomolecules possibly inducing non thermal-mediated biological effects at the cellular level. In this study, the occurrence of biochemical/biological modifications in human peripheral blood lympho-monocytes exposed in a reverberation chamber for times ranging from 1 to 20 h to EMFs at 1.8 GHz frequency and 200 V/m electric field strength was investigated. Morphological analysis of adherent cells unveiled, in some of these, appearance of an enlarged and deformed shape after EMFs exposure. Raman spectra of the nuclear compartment of cells exposed to EMFs revealed the onset of biochemical modifications, mainly consisting in the reduction of the DNA backbone-linked vibrational modes. Respirometric measurements of mitochondrial activity in intact lympho-monocytes resulted in increase of the resting oxygen consumption rate after 20 h of exposure, which was coupled to a significant increase of the FoF1 ATP synthase-related oxygen consumption. Notably, at lower time-intervals of EMFs exposure (i.e. 5 and 12 h) a large increase of the proton leak-related respiration was observed which, however, recovered at control levels after 20 h exposure. Confocal microscopy analysis of the mitochondrial membrane potential supported the respiratory activities whereas no significant variations in the mitochondrial mass/morphology was observed in EMFs-exposed lympho-monocytes. Finally, altered redox homeostasis was shown in EMFs-exposed lympho-monocytes, which progressed differently in nucleated cellular subsets. This results suggest the occurrence of adaptive mechanisms put in action, likely via redox signaling, to compensate for early impairments of the oxidative phosphorylation system caused by exposure to EMFs. Overall the data presented warn for health safety of people involved in long-term exposure to electromagnetic fields, although further studies are required to pinpoint the leukocyte cellular subset(s) selectively targeted by the EMFs action and the mechanisms by which it is achieved. PMID- 29462175 TI - Effect of cataract surgery on cognitive function in elderly: Results of Fujiwara kyo Eye Study. AB - PURPOSE: To determine whether there is a significant association between prior cataract surgery and cognitive function in an elderly Japanese cohort. SETTING: Nara Medical University, Nara, Japan. DESIGN: The Fujiwara-kyo Eye Study was a cross-sectional epidemiological study. METHODS: The subjects were >= 68-years who lived in the Nara Prefecture and responded to recruitment notices. All of the subjects received comprehensive ophthalmological examinations, and answered questionnaires on their socio-demographic and medical history including prior cataract surgery. The association between prior cataract surgery and cognitive function was determined. RESULTS: A total of the 2764 subjects whose mean age was 76.3+/-4.8 years (+/-standard deviation) was studied. Of these, 668 individuals (24.2%) had undergone cataract surgery. Of these, 150 (5.4%) had dementia as determined by the Mini-Mental State Examination (MMSE) score <=23, and 877 individuals (31.7%) had mild cognitive impairment (MCI; MMSE score 24-26). The subjects who had prior cataract surgery had significantly lower odds ratio (OR) of having MCI (OR = 0.78, 95% confidence interval; CI 0.64-0.96, P = 0.019) than those who had not had cataract surgery after adjusting for age, sex, body mass index, education, hypertension, diabetes, depression, and history of stroke. The OR was still lower when the visual acuity was also added to the adjusted factors (OR 0.79, 95% CI 0.64-0.97, P = 0.025). However, prior cataract surgery did not contribute significantly to the low OR for dementia. CONCLUSIONS: Cataract surgery may play a role in reducing the risk of developing MCI independently of visual acuity but not for dementia. PMID- 29462176 TI - Outcome of Enterococcus faecalis infective endocarditis according to the length of antibiotic therapy: Preliminary data from a cohort of 78 patients. AB - BACKGROUND: International guidelines recommend 4 weeks of treatment with ampicillin plus gentamicin (A+G) for uncomplicated native valve Enterococcus faecalis infective endocarditis (EFIE) and 6 weeks in the remaining cases. Ampicillin plus ceftriaxone (A+C) is always recommended for at least 6w, with no available studies assessing its suitability for 4w. We aimed to investigate differences in the outcome of EFIE according to the duration (4 versus 6 weeks) of antibiotic treatment (A+G or A+C). METHODS: Retrospective analysis from a prospectively collected cohort of 78 EFIE patients treated with either A+G or A+C. RESULTS: 32 cases (41%) were treated with A+G (9 for 4w, 28%) and 46 (59%) with A+C (14 for 4w, 30%). No significant differences were found in 1-year mortality according to the type of treatment (31% and 24% in A+G and A+C, respectively; P = 0.646) or duration (26% and 27% at 4 and 6w, respectively; P = 0.863). Relapses were more frequent among survivors treated for 4w than in those treated for 6w (3/18 [17%] at 4w and 1/41 [2%] at 6w; P = 0.045). Three out of 4 (75%) relapses occurred in cirrhotic patients. CONCLUSIONS: A 4-week course of antibiotic treatment might not be suitable neither for A+G nor A+C for treating uncomplicated native valve EFIE. PMID- 29462177 TI - Improving stability of prediction models based on correlated omics data by using network approaches. AB - Building prediction models based on complex omics datasets such as transcriptomics, proteomics, metabolomics remains a challenge in bioinformatics and biostatistics. Regularized regression techniques are typically used to deal with the high dimensionality of these datasets. However, due to the presence of correlation in the datasets, it is difficult to select the best model and application of these methods yields unstable results. We propose a novel strategy for model selection where the obtained models also perform well in terms of overall predictability. Several three step approaches are considered, where the steps are 1) network construction, 2) clustering to empirically derive modules or pathways, and 3) building a prediction model incorporating the information on the modules. For the first step, we use weighted correlation networks and Gaussian graphical modelling. Identification of groups of features is performed by hierarchical clustering. The grouping information is included in the prediction model by using group-based variable selection or group-specific penalization. We compare the performance of our new approaches with standard regularized regression via simulations. Based on these results we provide recommendations for selecting a strategy for building a prediction model given the specific goal of the analysis and the sizes of the datasets. Finally we illustrate the advantages of our approach by application of the methodology to two problems, namely prediction of body mass index in the DIetary, Lifestyle, and Genetic determinants of Obesity and Metabolic syndrome study (DILGOM) and prediction of response of each breast cancer cell line to treatment with specific drugs using a breast cancer cell lines pharmacogenomics dataset.

AB - Early fertilizer nitrogen (N) application on cover crops or their residues during the off-season is a practice adopted in Brazil subtropical conditions under no tillage corn (Zea mays L.) systems. However, the effect of early N application on yield, plant N content, and N recovery efficiency (NRE) for corn is not yet well documented. Five fertilizer N timings in an oat-corn system were evaluated in two studies utilizing an isotopic-labeled N determination, 15N isotope. The N fertilization timings were: (i) oat tillering, (ii) 15 days before corn planting time, over the oat residues, (iii) at corn planting time, (iv) in-season at the three-leaf growth stage (V3), and (v) in-season split application at V3 and six leaf (V6) growth stages. Based on the statistical analysis, the N fertilization timings were separated into three groups: 1) N-OATS, designated to N applied at oat; 2) N-PLANT, referred to pre-plant and planting N applications; and 3) N CORN, designated to in-season corn N applications. Corn yield was not affected by the N fertilization timing. However, the N-CORN N fertilization timings enhanced NRE by 17% and 35% and final N recovery system (plant plus soil) by 16% and 24% all relative to N-OATS and N-PLANT groups, respectively. Overall, N-OATS resulted in the largest N derived from fertilizer (NDFF) amount in the deeper soil layer, in overall a delta of 10 kg N ha-1 relative to the rest of the groups. Notwithstanding corn yield was not affected, early N fertilization under subtropical conditions is not a viable option since NRE was diminished and the non-recovery N increased relative to the in-season N applications. PMID- 29462180 TI - Physician referral patterns and racial disparities in total hip replacement: A network analysis approach. AB - BACKGROUND: Efforts to reduce racial disparities in total hip replacement (THR) have focused mainly on patient behaviors. While these efforts are no doubt important, they ignore the potentially important role of provider- and system level factors, which may be easier to modify. We aimed to determine whether the patterns of interaction among physicians around THR episodes differ in communities with low versus high concentrations of black residents. MATERIALS AND METHODS: We analyzed national Medicare claims from 2008 to 2011, identifying all fee-for-service beneficiaries who underwent THR. Based on physician encounter data, we then mapped the physician referral networks at the hospitals where beneficiaries' procedures were performed. Next, we measured two structural properties of these networks that could affect care coordination and information sharing: clustering, and the number of external ties. Finally, we estimated multivariate regression models to determine the relationship between the concentration of black residents in the community [as measured by the hospital service area (HSA)] served by a given network and each of these 2 network properties. RESULTS: Our sample included 336,506 beneficiaries (mean age 76.3 +/- SD), 63.1% of whom were women. HSAs with higher concentrations of black residents tended to be more impoverished than those with lower concentrations. While HSAs with higher concentrations of black residents had, on average, more acute care beds and medical specialists, they had fewer surgeons per capita than those with lower concentrations. After adjusting for these differences, we found that HSAs with higher concentrations of black residents were served by physician referral networks that had significantly higher within-network clustering but fewer external ties. CONCLUSIONS: We observed differences in the patterns of interaction among physicians around THR episodes in communities with low versus high concentrations of black residents. Studies investigating the impact of these differences on access to quality providers and on THR outcomes are needed. PMID- 29462179 TI - Patient navigators for people with chronic disease: A systematic review. AB - BACKGROUND: People with chronic diseases experience barriers to managing their diseases and accessing available health services. Patient navigator programs are increasingly being used to help people with chronic diseases navigate and access health services. OBJECTIVE: The objective of this review was to summarize the evidence for patient navigator programs in people with a broad range of chronic diseases, compared to usual care. METHODS: We searched MEDLINE, EMBASE, CENTRAL, CINAHL, PsycINFO, and Social Work Abstracts from inception to August 23, 2017. We also searched the reference lists of included articles. We included original reports of randomized controlled trials of patient navigator programs compared to usual care for adult and pediatric patients with any one of a defined set of chronic diseases. RESULTS: From a total of 14,672 abstracts, 67 unique studies fit our inclusion criteria. Of these, 44 were in cancer, 8 in diabetes, 7 in HIV/AIDS, 4 in cardiovascular disease, 2 in chronic kidney disease, 1 in dementia and 1 in patients with more than one condition. Program characteristics varied considerably. Primary outcomes were most commonly process measures, and 45 of 67 studies reported a statistically significant improvement in the primary outcome. CONCLUSION: Our findings indicate that patient navigator programs improve processes of care, although few studies assessed patient experience, clinical outcomes or costs. The inability to definitively outline successful components remains a key uncertainty in the use of patient navigator programs across chronic diseases. Given the increasing popularity of patient navigators, future studies should use a consistent definition for patient navigation and determine which elements of this intervention are most likely to lead to improved outcomes.

AB - Depression is a relevant risk factor for low back pain and is associated with the outcomes of low back pain. Depression also often overlaps with somatisation. As previous studies have suggested that somatisation or a higher somatic symptom burden has a role in the outcomes of low back pain, the aim of the present cross sectional study was to examine whether somatic symptom burden was associated with health-related quality of life in individuals with chronic low back pain independent of depression. We analyzed internet survey data on physical and mental health in Japanese adults aged 20-64 years with chronic low back pain (n = 3,100). Health-related quality of life was assessed using the EuroQol five dimensions (EQ-5D) questionnaire. Somatic symptom burden and depression were assessed using the Somatic Symptom Scale-8 (SSS-8) and the Patient Health Questionnaire-2 (PHQ-2), respectively. SSS-8 score was categorized as no to minimal (0-3), low (4-7), medium (8-11), high (12-15), and very high (16-32). The association between SSS-8 and EQ-5D was examined using linear regression models, adjusting for depression and other covariates, including age, sex, BMI, smoking, marital status, education, exercise, employment, and the number of comorbid diseases. A higher somatic symptom burden was significantly associated with a lower health-related quality of life independent of depression and the number of comorbid diseases (regression coefficient = 0.040 for SSS-8 high vs. very high and 0.218 for non to minimal vs. very high, p trend <0.0001). In conclusion, somatic symptom burden might be important for the health-related quality of life of individuals with chronic low back pain. PMID- 29462182 TI - Exercise-induced cardiac remodeling in non-elite endurance athletes: Comparison of 2-tiered and 4-tiered classification of left ventricular hypertrophy. AB - BACKGROUND: Long-term endurance sport practice leads to eccentric left ventricular hypertrophy (LVH). We aimed to compare the new 4-tiered classification (4TC) for LVH with the established 2-tiered classification (2TC) in a cohort of normotensive non-elite endurance athletes. METHODS: Male participants of a 10-mile race were recruited and included when blood pressure (BP) was normal (<140/90 mmHg). Phenotypic characterization of LVH was based on relative wall thickness (2TC), and on LV concentricity2/3 (LV mass/end-diastolic volume [LVM/EDV]2/3) plus LVEDV index (4TC). Parameters of LV geometry, BP, cumulative training hours, and race time were compared between 2TC and 4TC by analysis of variance, and post-hoc analysis. RESULTS: Of 198 athletes recruited, 174 were included. Mean age was 41.6+/-7.5 years. Forty-two (24%) athletes had LVH. Allocation in the 2TC was: 32 (76%) eccentric LVH and 10 (24%) concentric LVH. Using the 4TC 12 were reclassified to concentric LVH, and 2 to eccentric LVH, resulting in 22 (52%) eccentric LVH (7 non-dilated, 15 dilated), and 20 (48%) concentric LVH (all non-dilated). Based on the 2TC, markers of endurance training did not differ between eccentric and concentric LVH. Based on the 4TC, athletes with eccentric LVH had more cumulative training hours and faster race times, with highest values thereof in athletes with eccentric dilated LVH. CONCLUSIONS: In our cohort of normotensive endurance athletes, the new 4TC demonstrated a superior discrimination of exercise-induced LVH patterns, compared to the established 2TC, most likely because it takes three-dimensional information of the ventricular geometry into account. PMID- 29462183 TI - Galanin is an epigenetically silenced tumor suppressor gene in gastric cancer cells. AB - Galanin is a 30 amino-acid active neuropeptide that acts via three G-protein coupled galanin receptors, GALR1, GALR2 and GALR3. Recently, GALR1 was also suggested as a tumor suppressor gene that was frequently silenced in head and neck squamous cell carcinoma; moreover, galanin and GALR1 were reported to inhibit human oral cancer cell proliferation. However, the exact role of galanin in gastric cancer is unclear. Here, we describe the epigenetic silencing of galanin in human gastric cancer. Five gastric cancer cell lines (SNU-1, SNU-601, SNU-638, KATOIII, and AGS) showed a significant reduction in galanin expression that was restored by the demethylating agent 5-aza-2'-deoxycytidine. We confirmed the hypermethylation of CpG islands in the galanin promoter region by methylation specific and bisulfate sequencing polymerase chain reaction (PCR). Interestingly, hypermethylated galanin did not affect galanin receptor expression. Exogenous galanin expression in silenced cells induced apoptosis and decreased phosphorylated Akt expression. Taken together, these data suggest that galanin hypermethylation impairs its tumor suppressor function in gastric cancer carcinogenesis. PMID- 29462184 TI - Interactome analysis of the lymphocytic choriomeningitis virus nucleoprotein in infected cells reveals ATPase Na+/K+ transporting subunit Alpha 1 and prohibitin as host-cell factors involved in the life cycle of mammarenaviruses. AB - Several mammalian arenaviruses (mammarenaviruses) cause hemorrhagic fevers in humans and pose serious public health concerns in their endemic regions. Additionally, mounting evidence indicates that the worldwide-distributed, prototypic mammarenavirus, lymphocytic choriomeningitis virus (LCMV), is a neglected human pathogen of clinical significance. Concerns about human pathogenic mammarenaviruses are exacerbated by of the lack of licensed vaccines, and current anti-mammarenavirus therapy is limited to off-label use of ribavirin that is only partially effective. Detailed understanding of virus/host-cell interactions may facilitate the development of novel anti-mammarenavirus strategies by targeting components of the host-cell machinery that are required for efficient virus multiplication. Here we document the generation of a recombinant LCMV encoding a nucleoprotein (NP) containing an affinity tag (rLCMV/Strep-NP) and its use to capture the NP-interactome in infected cells. Our proteomic approach combined with genetics and pharmacological validation assays identified ATPase Na+/K+ transporting subunit alpha 1 (ATP1A1) and prohibitin (PHB) as pro-viral factors. Cell-based assays revealed that ATP1A1 and PHB are involved in different steps of the virus life cycle. Accordingly, we observed a synergistic inhibitory effect on LCMV multiplication with a combination of ATP1A1 and PHB inhibitors. We show that ATP1A1 inhibitors suppress multiplication of Lassa virus and Candid#1, a live-attenuated vaccine strain of Junin virus, suggesting that the requirement of ATP1A1 in virus multiplication is conserved among genetically distantly related mammarenaviruses. Our findings suggest that clinically approved inhibitors of ATP1A1, like digoxin, could be repurposed to treat infections by mammarenaviruses pathogenic for humans. PMID- 29462186 TI - Lack of infrastructure, social and cultural factors limit physical activity among patients with type 2 diabetes in rural Sri Lanka, a qualitative study. AB - INTRODUCTION: South Asians have high prevalence of diabetes, increased cardiovascular risk and low levels of physical activity (PA). Reasons for low levels of PA have not previously been explored among Asians living within their endogenous environment. This qualitative study was performed to explore the contextual reasons that limited PA among type 2 diabetic patients living in a rural community. METHODS: Purposeful sampling recruited 40 participants with long standing type 2 diabetes for this qualitative study. Semi-structered questions utilising in-depth interviews were used to collect data on PA patterns, barriers to PA and factors that would facilitate PA. The interviews were digitally recorded and transcribed. Data were analyzed using a framework approach. RESULTS: The sample consisted of 11 males and 29 females. Mean age was 55.4 (SD 8.9) years. The mean duration of diabetes in the study population was 8.5 (SD 6.8) years. Inability to differentitate household and daily activities from PA emerged as a recurring theme. Most did not have a clear understanding of the type or duration of PA that they should perform. Health related issues, lifestyle and time management, envronmental and social factors like social embarrassment, prioritizing household activities over PA were important factors that limited PA. Most stated that the concept of exercising was alien to their culture and lifestyle. CONCLUSION: Culturally appropriate programmes that strengthen health education and empower communities to overcome socio-economic barriers that limit PA should be implemented to better manage diabetes among rural Sri Lankan diabetic patients. PMID- 29462185 TI - DHX29 functions as an RNA co-sensor for MDA5-mediated EMCV-specific antiviral immunity. AB - Melanoma differentiation-associated gene-5 (MDA5) recognizes distinct subsets of viruses including Encephalomyocarditis virus (EMCV) of picornavirus family, but the molecular mechanisms underlying the specificity of the viral recognition of MDA5 in immune cells remain obscure. DHX29 is an RNA helicase required for the translation of 5' structured mRNA of host and many picornaviruses (such as EMCV). We identify that DXH29 as a key RNA co-sensor, plays a significant role for specific recognition and triggering anti-EMCV immunity. We have observed that DHX29 regulates MDA5-, but not RIG-I-, mediated type I interferon signaling by preferentially interacting with structured RNAs and specifically with MDA5 for enhancing MDA5-dsRNA binding affinity. Overall, our results identify a critical role for DHX29 in innate immune response and provide molecular insights into the mechanisms by which DHX29 recognizes 5' structured EMCV RNA and interacts with MDA5 for potent type I interferon signaling and antiviral immunity. PMID- 29462187 TI - Genotyping and sero-virological characterization of hepatitis B virus (HBV) in blood donors, Southern Ethiopia. AB - Hepatitis B virus (HBV) prevalence is highest in Sub-Saharan Africa including Ethiopia. HBV genotypes have distinct geographic distributions and play a role in course of infection and treatment management. However, in Ethiopia there is paucity of information about distribution of HBV genotypes. This study was done to determine genotype, mutation and sero-virological profiles of HBV isolates in Southern Ethiopia. Cross-sectional, laboratory based study was conducted on 103HBsAg sero-positive samples from a total of 2,237 screened blood donors. HBV serological markers and biochemical assays were done. Serum viral load was measured using quantitative real-time PCR. Partial HBV S-gene was amplified with nested PCR and sequenced. Bioinformatics tools were utilized to determine genotypes, serotypes and mutations. Of 103 HBsAg reactive serum samples, 14.6% and 70.9% were sero-positive for HBeAg and HBeAb, respectively. Ninety-eight samples gave detectable viral load with a median of 3.46(2.62-4.82) log IU/ml. HBeAg sero-positive donors carried elevated levels of viral load. Eighty five isolates were successfully amplified, sequenced and genotyped into 58 (68.2%) genotype A (HBV/A) and 27 (31.8%) genotype D (HBV/D). HBV serotypes found were adw2 (74.1%), ayw2 (24.7%), and ayw3 (1.2%). In twenty-four (28.2%) samples mutations in the major hydrophilic region (MHR) were observed. Donors infected with HBV/A had higher viral load and more frequent MHR mutation than HBV/D infected donors. This study illustrated distribution of HBV genotype A and D among blood donors in southern Ethiopia. It also demonstrated occurrence HBV variants that may influence clinical aspects of HBV infection. The study contributes in narrowing the existing gap of HBV molecular study in Ethiopia.

AB - Like humans, monkeys value information about sex and status, inviting the hypothesis that our susceptibility to these factors in advertising arises from shared, ancestral biological mechanisms that prioritize social information. To test this idea, we asked whether rhesus macaques (Macaca mulatta) show choice behavior that is similar to humans in response to sex and social status in advertising. Our results show that monkeys form preferences for brand logos repeatedly paired with images of macaque genitals and high status monkeys. Moreover, monkeys sustain preferences for these brand logos even though choosing them provided no tangible rewards, a finding that cannot be explained by a decision mechanism operating solely on material outcomes. Together, our results endorse the hypothesis that the power of sex and status in advertising emerges from the spontaneous engagement of shared, ancestral neural circuits that prioritize information useful for navigating the social environment. Finally, our results show that simple associative conditioning is sufficient to explain the formation of preferences for brand logos paired with sexual or status-based images. PMID- 29462190 TI - Divergent bornaviruses from Australian carpet pythons with neurological disease date the origin of extant Bornaviridae prior to the end-Cretaceous extinction. AB - Tissue samples from Australian carpet pythons (Morelia spilota) with neurological disease were screened for viruses using next-generation sequencing. Coding complete genomes of two bornaviruses were identified with the gene order 3'-N-X-P G-M-L, representing a transposition of the G and M genes compared to other bornaviruses and most mononegaviruses. Use of these viruses to search available vertebrate genomes enabled recognition of further endogenous bornavirus-like elements (EBLs) in diverse placental mammals, including humans. Codivergence patterns and shared integration sites revealed an ancestral laurasiatherian EBLG integration (77 million years ago [MYA]) and a previously identified afrotherian EBLG integration (83 MYA). The novel python bornaviruses clustered more closely with these EBLs than with other exogenous bornaviruses, suggesting that these viruses diverged from previously known bornaviruses prior to the end-Cretaceous (K-Pg) extinction, 66 MYA. It is possible that EBLs protected mammals from ancient bornaviral disease, providing a selective advantage in the recovery from the K-Pg extinction. A degenerate PCR primer set was developed to detect a highly conserved region of the bornaviral polymerase gene. It was used to detect 15 more genetically distinct bornaviruses from Australian pythons that represent a group that is likely to contain a number of novel species.

PMID- 29462191 TI - Higher serum choline and betaine levels are associated with better body composition in male but not female population. AB - BACKGROUND: Animal studies proved that choline and betaine have beneficial effect on reducing body fat. However, evidence in humans is scarce. We aim to investigate the association between serum choline and betaine levels with body composition in general population. METHODS: This is an observational cross sectional study performed in 1081 subjects from the CODING (Complex Disease in Newfoundland population: Environment and Genetics) study. Serum choline and betaine levels were measured based on liquid chromatography coupled with tandem mass spectrometry technology. Body composition was measured using dual-energy X ray absorptiometry following a 12-hour fast. Major confounding factors including age, sex, total calorie intake and physical activity level were controlled in all analyses. RESULTS: Significantly inverse correlations were found between serum betaine levels and all obesity measurements in males (r ranged from -0.12 to 0.23, and p<0.01 for all) but not in females. Serum choline was negatively associated with total percent body fat (%BF), percent trunk fat (%TF), weight, body mass index (BMI), waist circumference (WC), and waist-to-hip ratio (r ranged from -0.11 to -0.19, and p<0.05 for all) in males and positively associated with weight, BMI and WC (r ranged from 0.09 to 0.10, and p<0.05 for all) in females. The negative associations between serum choline and betaine levels with obesity in males were more profound in those not on any medication than those taking medications. Moreover, obese males had the lowest serum choline and betaine levels, followed by overweight males, and normal weight males having the highest serum choline and betaine levels, especially in those not taking medications (p<0.05). Likewise, subjects with the highest serum levels of both had the lowest obesity indexes, especially those not taking medications. CONCLUSIONS: Higher serum choline and betaine levels were associated with a more favorable body composition (lower body fat and higher lean body mass) in males and the favorable association was more pronounced in non-medication users. PMID- 29462193 TI - The influence of different fever definitions on diagnostics and treatment after diagnosis of fever in chemotherapy-induced neutropenia in children with cancer. AB - BACKGROUND: There is no evidence-based definition of the temperature limit defining fever (TLDF) in children with neutropenia. Lowering the TLDF is known to increase the number of episodes of fever in neutropenia (FN). This study aimed to investigate the influence of a lower versus standard TLDF on diagnostics and therapy. METHODS: In a single pediatric cancer center using a high standard TLDF (39 degrees C tympanic-temperature) patients were observed prospectively (NCT01683370). The effect of applying lower TLDFs (range 37.5 degrees C to 38.9 degrees C) versus 39.0 degrees C on these measures was simulated in silicon. RESULTS: In reality, 45 FN episodes were diagnosed. Of 3391 temperatures measured, 193 were >=39.0 degrees C, and 937 >=38.0 degrees C. For persisting fever >=24 hours, additional blood cultures were taken in 31 (69%) episodes in reality. This number decreased to 22 (49%) when applying 39.0 degrees C, and increased to 33 for 38.0 degrees C (73%; plus 11 episodes; plus 24%). For persisting fever >=48 hours, i.v.-antibiotics were escalated in 25 (56%) episodes. This number decreased to 15 (33%) when applying 39.0 degrees C, and increased to 26 for 38.0 degrees C (58%; plus 11 episodes; plus 24%). For persisting fever >=120 hours, i.v.-antifungals were added in 4 (9%) episodes. This number increased to 6 (13%) by virtually applying 39.0 degrees C, and to 11 for 38.0 degrees C (24%; plus 5 episodes; plus 11%). The median length of stay was 5.7 days (range, 0.8 to 43.4). In 43 episodes with hospital discharge beyond 24 hours, applying 38.0 degrees C led to discharge delay by >=12 hours in 24 episodes (56%; 95% CI, 40 to 71), with a median delay of 13 hours, and a cumulative delay of 68 days. CONCLUSION: Applying a low versus standard TLDF led to relevant increases of diagnostics, antimicrobial therapy, and length of stay. The differences between management in reality versus simply applying 39.0 degrees as TLDF reflect the important impact of clinical assessment. PMID- 29462194 TI - Enhancing healthcare accessibility measurements using GIS: A case study in Seoul, Korea. AB - With recent aging demographic trends, the needs for enhancing geo-spatial analysis capabilities and monitoring the status of accessibilities of its citizens with healthcare services have increased. The accessibility to healthcare is determined not only by geographic distances to service locations, but also includes travel time, available modes of transportation, and departure time. Having access to the latest and accurate information regarding the healthcare accessibility allows the municipal government to plan for improvements, including expansion of healthcare infrastructure, effective labor distribution, alternative healthcare options for the regions with low accessibilities, and redesigning the public transportation routes and schedules. This paper proposes a new method named, Seoul Enhanced 2-Step Floating Catchment Area (SE2SFCA), which is customized for the city of Seoul, where population density is higher and the average distance between healthcare-service locations tends to be shorter than the typical North American or European cities. The proposed method of SE2SFCA is found to be realistic and effective in determining the weak accessibility regions. It resolves the over-estimation issues of the past, arising from the assignment of high healthcare accessibility for the regions with large hospitals and high density of population and hospitals.

AB - The patients' inhalation flow pattern is one of the significant determinants for clinical performance of inhalation therapy. However, the development of inhalation flow meters for various inhalation devices has been unable to keep up with the increasing number of newly launched inhalation devices. In the present study, we developed simple attachment orifices for the inhalation flow pattern monitoring system, which are suitable for all commercial inhalers, and investigated the efficacy of the system on the clinical inhalation instruction for patients co-prescribed dry powder inhaler (DPI) and soft mist inhaler (SMI). First, we constructed simple attachment orifices that were adjusted for 13 commercial inhalers, and examined the correlation between orifice and inhalation device. Second, the inhalation flow patterns (peak inspiratory flow rate, PIFR; inhalation duration time, DT) of patients prescribed a combination of DPI and SMI were monitored before and after inhalation instruction. The inhalation resistance of commercial inhalers are listed in the following order; Twincaps(r) > Handihaler(r) > Swinghaler(r) = Clickhaler(r) > Twisthaler(r) > Turbuhaler(r) > Jenuair(r) > Diskus(r) = Ellipta(r) > Diskhaler(r) > Breezhaler(r) > Respimat(r) = pMDI. The pressure drop via orifice was significantly correlated with that via the commercial inhaler. For the confirmation, all participants achieved the DPI criterion of PIFR. On the other hand, 4 participants (6 clinical visits) of 10 experimented participants could not achieve the essential criterion of DT (> 1.5 sec) for SMI, but all participants improved their duration time after inhalation instruction by pharmacists (P<0.05). In the present study, we successfully developed simple attachment orifice suitable for 13 commercial inhalation devices. These data suggested that our simple attachment orifices for the inhalation flow pattern monitoring system can detect patients with inadequate inhalation patterns via SMI. PMID- 29462196 TI - Interior renovation of a general practitioner office leads to a perceptual bias on patient experience for over one year. AB - INTRODUCTION: Measuring patient experience is key when assessing quality of care but can be biased: A perceptual bias occurs when renovations of the interior design of a general practitioner (GP) office improves how patients assessed quality of care. The aim was to assess the length of perceptual bias and if it could be reproduced after a second renovation. METHODS: A GP office with 2 GPs in Switzerland was renovated twice within 3 years. We assessed patient experience at baseline, 2 months and 14 months after the first and 3 months after the second renovation. Each time, we invited a sample of 180 consecutive patients that anonymously graded patient experience in 4 domains: appearance of the office; qualities of medical assistants and GPs; and general satisfaction. We compared crude mean scores per domain from baseline until follow-up. In a multivariate model, we adjusted for patient's age, gender and for how long patients had been their GP. RESULTS: At baseline, patients aged 60.9 (17.7) years, 52% females. After the first renovation, we found a regression to the baseline level of patient experience after 14 months except for appearance of the office (p<0.001). After the second renovation, patient experience improved again in appearance of the office (p = 0.008), qualities of the GP (p = 0.008), and general satisfaction (p = 0.014). Qualities of the medical assistant showed a slight improvement (p = 0.068). Results were unchanged in the multivariate model. CONCLUSIONS: Interior renovation of a GP office probably causes a perceptual bias for >1 year that improves how patients rate quality of care. This bias could be reproduced after a second renovation strengthening a possible causal relationship. These findings imply to appropriately time measurement of patient experience to at least one year after interior renovation of GP practices to avoid environmental changes influences the estimates when measuring patient experience. PMID- 29462197 TI - Thymic epithelial cell-derived signals control B progenitor formation and proliferation in the thymus by regulating Let-7 and Arid3a. AB - The postnatal thymus is an efficient microenvironment for T cell specification and differentiation. B cells are also present in the thymus and have been recently shown to impact T cell selection, however, the mechanisms controlling B cell development in the thymus are largely unknown. In Foxn1lacZ mutant mice, down-regulation of Foxn1 expression in thymic epithelial cells beginning 1 week after birth caused a dramatic reduction of T progenitors and an increase of B cell progenitors. This time point is coincident with the switch from fetal to adult-type hematopoietic stem cells (HSCs), which is regulated by the Lin28-Let7 system. We hypothesize that the thymic environment might regulate this process to suppress fetal-type B cell development in the thymus. In this study we show that in the Foxn1lacZ thymus, although the down-regulation of Lin28 in thymocytes was normal, up-regulation of Let-7 was impaired. The failure to up-regulate Let-7 caused a transient increase of Arid3a in B precursors, which is known to promote fetal-type B cell fate. Over-expression of Lin28a in HSCs also reduced Let-7 and promoted Arid3a expression in BM and thymic B progenitors, increasing B cell production in the thymus. The level of Let-7 in thymic B progenitors was up regulated by in vitro co-culture with IL15, Vitamin-D3, and retinoic acid, thus down-regulating Arid3a to promote B cell differentiation. All of these signals were produced in thymic epithelial cells (TECs) related to Let-7 expression in thymic B progenitors, and down-regulated in Foxn1lacZ mutants. Our data show that signals provided by TEC control thymic B cell development by up-regulating Let-7, suppressing Arid3a expression in intrathymic progenitor B cells to limit their proliferation during the neonatal to adult transition. PMID- 29462198 TI - Hexokinase 2 is a molecular bridge linking telomerase and autophagy. AB - Autophagy is systematically regulated by upstream factors and nutrients. Recent studies reported that telomerase and hexokinase 2 [HK2) regulate autophagy through mTOR and that telomerase has the capacity to bind to the HK2 promoter. However, the molecular linkage among telomerase, HK2, and autophagy is not fully understood. Here, we show that HK2 connects telomerase to autophagy. HK2 inhibition in HepG2 cells suppressed TERT-induced autophagy activation and further enhancement by glucose deprivation. The HK2 downstream factor mTOR was responsible for the TERT-induced autophagy activation under glucose deprivation, implying that TERT promotes autophagy through an HK2-mTOR pathway. TERC played a role similar to that of TERT, and simultaneous expression of TERT and TERC synergistically enhanced HK2 expression and autophagy. At the gene level, TERT bound to the HK2 promoter at a specific region harboring the telomerase responsive sequence 'TTGGG.' Mutagenesis of TERC and the TERT-responsive element in the HK2 promoter revealed that TERC is required for the binding of TERT to the HK2 promoter. We demonstrate the existence of a telomerase-HK2-mTOR-autophagy axis and suggest that inhibition of the interaction between telomerase and the HK2 promoter diminishes glucose starvation-induced autophagy.

AB - Understanding the role of diet in the physiological condition of adults during reproduction and hence its effect on reproductive performance is fundamental to understand reproductive strategies in long-lived animals. In birds, little is known about the influence of the quality of food consumed at the beginning of the reproductive period and its short-term effects on reproductive performance. To assess the role of diet in the physiological condition of female blue-footed booby, Sula nebouxii (BFBO), during reproduction we evaluated whether individual differences in diet (assessed by using delta13C and delta15N values of whole blood from female birds and muscle tissue of the principal prey species) prior to egg laying and during incubation influenced their lipid metabolic profile (measured as triglyceride levels and C:N ratio) and their reproductive performance (defined by laying date, clutch size and hatching success). Females with higher delta15N values in their blood during the courtship and incubation periods had a higher lipid metabolic profile, earlier laying date, greater clutch size (2-3 eggs) and higher hatching success. Females that laid earlier and more eggs (2-3 eggs) consumed more Pacific anchoveta (Cetengraulis mysticetus) and Pacific thread herring (Opisthonema libertate) than did other females. These two prey species also had high amounts of lipids (C:N ratio) and caloric content (Kcal/g fresh weight). The quality of food consumed by females at the beginning of reproduction affected their physiological condition, as well as their short term reproductive performance. Our work emphasizes the importance of determining the influence of food quality during reproduction to understand the reproductive decisions and consequences in long-lived animals. PMID- 29462200 TI - A prophylactic multivalent vaccine against different filovirus species is immunogenic and provides protection from lethal infections with Ebolavirus and Marburgvirus species in non-human primates. AB - The search for a universal filovirus vaccine that provides protection against multiple filovirus species has been prompted by sporadic but highly lethal outbreaks of Ebolavirus and Marburgvirus infections. A good prophylactic vaccine should be able to provide protection to all known filovirus species and as an upside potentially protect from newly emerging virus strains. We investigated the immunogenicity and protection elicited by multivalent vaccines expressing glycoproteins (GP) from Ebola virus (EBOV), Sudan virus (SUDV), Tai Forest virus (TAFV) and Marburg virus (MARV). Immune responses against filovirus GP have been associated with protection from disease. The GP antigens were expressed by adenovirus serotypes 26 and 35 (Ad26 and Ad35) and modified Vaccinia virus Ankara (MVA) vectors, all selected for their strong immunogenicity and good safety profile. Using fully lethal NHP intramuscular challenge models, we assessed different vaccination regimens for immunogenicity and protection from filovirus disease. Heterologous multivalent Ad26-Ad35 prime-boost vaccination regimens could give full protection against MARV (range 75%-100% protection) and EBOV (range 50% to 100%) challenge, and partial protection (75%) against SUDV challenge. Heterologous multivalent Ad26-MVA prime-boost immunization gave full protection against EBOV challenge in a small cohort study. The use of such multivalent vaccines did not show overt immune interference in comparison with monovalent vaccines. Multivalent vaccines induced GP-specific antibody responses and cellular IFNgamma responses to each GP expressed by the vaccine, and cross reactivity to TAFV GP was detected in a trivalent vaccine expressing GP from EBOV, SUDV and MARV. In the EBOV challenge studies, higher humoral EBOV GP specific immune responses (p = 0.0004) were associated with survival from EBOV challenge and less so for cellular immune responses (p = 0.0320). These results demonstrate that it is feasible to generate a multivalent filovirus vaccine that can protect against lethal infection by multiple members of the filovirus family. PMID- 29462201 TI - Trend of estimated glomerular filtration rate during ombistasvir/paritaprevir/ritonavir plus dasabuvir +/- ribavirin in HIV/HCV co infected patients. AB - The renal function is a key-issue in HIV/HCV co-infected patients, nevertheless, it has not established so far whether HCV treatment with new direct acting agents could impact on estimated glomerular filtration rate (eGFR) variations. In the present work, we examined the real-life data on renal function that have been prospectively collected in the SIMIT compassionate-use program of ombitasvir/paritaprevir/ritonavir plus dasabuvir (OBV/PTV/r + DSV) in 144 HIV/HCV genotype 1 co-infected patients. The population was 74% male, 30.5% in CDC stage C, with median age of 52 years (48.0-56.5) and median liver stiffness of 7.8 kPa (6.7-9.2). Median baseline eGFR was 102.0 (90.8-108.1), changing to 99.8 (83.5 104.8) at the end of treatment (EoT), and 100.0 (87.3-105.6) 12 weeks after the EoT (FU12), p<0.0001. No patient had grade 3-4 increase of creatinine. At EoT 60/144 (41.7%) patients had >= 5% reduction in their eGFR, confirmed at FU12 in 39/60 (65.0%) cases. Longer duration of HCV infection (cut-off 12.9 years), lower HCV-RNA viral load (cut-off 1,970,160 IU/ml) and lower platelet count (cut-off 167,000 x106/L) were significantly associated with eGFR decline at logistic analysis (adjOR 2.9, 95%CI 1.0-8.8, p = 0.05; adjOR 3.5, 95%CI 1.2-10.4, p = 0.02; adjOR 2.8, 95%CI 1.1-6.8, p = 0.03, respectively). After repeating the analysis throughout a mixed model, a higher eGFR decline was highlighted in patients concomitantly treated with tenofovir (p = 0.0001), ribavirin (p = 0.0001), or integrase inhibitors (p <0.0001), with longer duration of HIV (p = 0.0002) and HCV infection (p = 0.035), lower baseline HCV RNA (p <0.0001), previous HCV treatment (p<0.0001), and older age (p<0.0001). In conclusion, our study confirms a good renal safety profile of OBV/PTV/r + DSV treatment in HIV/HCV patients, and the median decline of 2 ml/min in eGFR, albeit statistically significant, is of doubtful clinical significance. The role of aging, concomitant therapies and duration of HIV/HCV infection needs to be further investigated. PMID- 29462202 TI - Thymic B cell development is controlled by the B potential of progenitors via both hematopoietic-intrinsic and thymic microenvironment-intrinsic regulatory mechanisms. AB - BACKGROUND: Hematopoietic stem cells (HSCs) derived from birth through adult possess differing differentiation potential for T or B cell fate in the thymus; neonatal bone marrow (BM) cells also have a higher potential for B cell production in BM compared to adult HSCs. We hypothesized that this hematopoietic intrinsic B potential might also regulate B cell development in the thymus during ontogeny. METHODS: Foxn1lacZ mutant mice are a model in which down regulation of a thymic epithelial cell (TEC) specific transcription factor beginning one week postnatal causes a dramatic reduction of thymocytes production. In this study, we found that while T cells were decreased, the frequency of thymic B cells was greatly increased in these mutants in the perinatal period. We used this model to characterize the mechanisms in the thymus controlling B cell development. RESULTS: Foxn1lacZ mutants, T cell committed intrathymic progenitors (DN1a,b) were progressively reduced beginning one week after birth, while thymic B cells peaked at 3-4 weeks with pre-B-II progenitor phenotype, and originated in the thymus. Heterochronic chimeras showed that the capacity for thymic B cell production was due to a combination of higher B potential of neonatal HSCs, combined with a thymic microenvironment deficiency including reduction of DL4 and increase of IL-7 that promoted B cell fate. CONCLUSION: Our findings indicate that the capacity and time course for thymic B-cell production are primarily controlled by the hematopoietic-intrinsic potential for B cells themselves during ontogeny, but that signals from TECs microenvironment also influence the frequency and differentiation potential of B cell development in the thymus. PMID- 29462203 TI - A generic HTS assay for kinase screening: Validation for the isolation of an engineered malate kinase. AB - An end-point ADP/NAD+ acid/alkali assay procedure, directly applicable to library screening of any type of ATP-utilising/ADP producing enzyme activity, was implemented. Typically, ADP production is coupled to NAD+ co-enzyme formation by the conventional addition of pyruvate kinase and lactate dehydrogenase. Transformation of enzymatically generated NAD+ into a photometrically active alkali derivative product is then achieved through the successive application of acidic/alkali treatment steps. The assay was successfully miniaturized to search for malate kinase activity in a structurally-guided library of LysC aspartate kinase variants comprising 6,700 clones. The screening procedure enabled the isolation of nine positive variants showing novel kinase activity on (L)-malate, the best mutant, LysC V115A:E119S:E434V exhibited strong substrate selectivity for (L)-malate compared to (L)-aspartate with a (kcat/Km)malate/(kcat/Km)aspartate ratio of 86. Double mutants V115A:E119S, V115A:E119C and E119S:E434V were constructed to further probe the origins of stabilising substrate binding energy gains for (L)-malate due to mutation. The introduction of less sterically hindering side-chains in engineered enzymes carrying E119S and V115A mutations increases the effective volume available for substrate binding in the catalytic pocket. Improved binding of the (L)-malate substrate may be assisted by less hindered movement of the Phe184 aromatic side chain. Additional favourable long-range electostatic effects on binding arising from the E434V surface mutation are conditionally dependent upon the presence of the V115A mutation close to Phe184 in the active-site. PMID- 29462204 TI - Microbial diversity and component variation in Xiaguan Tuo Tea during pile fermentation. AB - Xiaguan Tuo Tea is largely consumed by the Chinese, but there is little research into the microbial diversity and component changes during the fermentation of this tea. In this study, we first used fluorescence in situ hybridization (FISH), next-generation sequencing (NGS) and chemical analysis methods to determine the microbial abundance and diversity and the chemical composition during fermentation. The FISH results showed that the total number of microorganisms ranges from 2.3*102 to 4.0*108 cells per gram of sample during fermentation and is mainly dominated by fungi. In the early fermentation stages, molds are dominant (0.6*102~2.8*106 cells/g, 0~35 d). However, in the late stages of fermentation, yeasts are dominant (3.6*104~9.6*106 cells/g, 35~56 d). The bacteria have little effect during the fermentation of tea (102~103 cells/g, <1% of fungus values). Of these fungi, A. niger (Aspergillus niger) and B. adeninivorans (Blastobotrys adeninivorans) are identified as the two most common strains, based on Next-generation Sequencing (NGS) analysis. Peak diversity in tea was observed at day 35 of fermentation (Shannon-Weaver index: 1.195857), and lower diversity was observed on days 6 and 56 of fermentation (Shannon-Weaver index 0.860589 and 1.119106, respectively). During the microbial fermentation, compared to the unfermented tea, the tea polyphenol content decreased by 54%, and the caffeine content increased by 59%. Theanine and free amino acid contents were reduced during fermentation by 81.1 and 92.85%, respectively. PMID- 29462205 TI - Spatial analysis of ecosystem service relationships to improve targeting of payments for hydrological services. AB - Payment for hydrological services (PHS) are popular tools for conserving ecosystems and their water-related services. However, improving the spatial targeting and impacts of PHS, as well as their ability to foster synergies with other ecosystem services (ES), remain challenging. We aimed at using spatial analyses to evaluate the targeting performance of Mexico's National PHS program in central Veracruz. We quantified the effectiveness of areas targeted for PHS in actually covering areas of high HS provision and social priority during 2003 2013. First, we quantified provisioning and spatial distributions of two target (water yield and soil retention), and one non-target ES (carbon storage) using InVEST. Subsequently, pairwise relationships among ES were quantified by using spatial correlation and overlap analyses. Finally, we evaluated targeting by: (i) prioritizing areas of individual and overlapping ES; (ii) quantifying spatial co occurrences of these priority areas with those targeted by PHS; (iii) evaluating the extent to which PHS directly contribute to HS delivery; and (iv), testing if PHS targeted areas disproportionately covered areas with high ecological and social priority. We found that modelled priority areas exhibited non-random distributions and distinct spatial patterns. Our results show significant pairwise correlations between all ES suggesting synergistic relationships. However, our analysis showed a significantly lower overlap than expected and thus significant mismatches between PHS targeted areas and all types of priority areas. These findings suggest that the targeting of areas with high HS provisioning and social priority by Mexico's PHS program could be improved significantly. This study underscores: (1) the importance of using maps of HS provisioning as main targeting criteria in PHS design to channel payments towards areas that require future conservation, and (2) the need for future research that helps balance ecological and socioeconomic targeting criteria. PMID- 29462206 TI - Cell-free synthesis of functional antibody fragments to provide a structural basis for antibody-antigen interaction. AB - Growing numbers of therapeutic antibodies offer excellent treatment strategies for many diseases. Elucidation of the interaction between a potential therapeutic antibody and its target protein by structural analysis reveals the mechanism of action and offers useful information for developing rational antibody designs for improved affinity. Here, we developed a rapid, high-yield cell-free system using dialysis mode to synthesize antibody fragments for the structural analysis of antibody-antigen complexes. Optimal synthesis conditions of fragments (Fv and Fab) of the anti-EGFR antibody 059-152 were rapidly determined in a day by using a 30-MUl-scale unit. The concentration of supplemented disulfide isomerase, DsbC, was critical to obtaining soluble antibody fragments. The optimal conditions were directly applicable to a 9-ml-scale reaction, with linear scalable yields of more than 1 mg/ml. Analyses of purified 059-152-Fv and Fab showed that the cell-free synthesized antibody fragments were disulfide-bridged, with antigen binding activity comparable to that of clinical antibodies. Examination of the crystal structure of cell-free synthesized 059-152-Fv in complex with the extracellular domain of human EGFR revealed that the epitope of 059-152-Fv broadly covers the EGF binding surface on domain III, including residues that formed critical hydrogen bonds with EGF (Asp355EGFR, Gln384EGFR, H409EGFR, and Lys465EGFR), so that the antibody inhibited EGFR activation. We further demonstrated the application of the cell-free system to site-specific integration of non-natural amino acids for antibody engineering, which would expand the availability of therapeutic antibodies based on structural information and rational design. This cell-free system could be an ideal antibody-fragment production platform for functional and structural analysis of potential therapeutic antibodies and for engineered antibody development. PMID- 29462207 TI - Karyotype evolution in Phalaris (Poaceae): The role of reductional dysploidy, polyploidy and chromosome alteration in a wide-spread and diverse genus. AB - Karyotype characteristics can provide valuable information on genome evolution and speciation, in particular in taxa with varying basic chromosome numbers and ploidy levels. Due to its worldwide distribution, remarkable variability in morphological traits and the fact that ploidy change plays a key role in its evolution, the canary grass genus Phalaris (Poaceae) is an excellent study system to investigate the role of chromosomal changes in species diversification and expansion. Phalaris comprises diploid species with two basic chromosome numbers of x = 6 and 7 as well as polyploids based on x = 7. To identify distinct karyotype structures and to trace chromosome evolution within the genus, we apply fluorescence in situ hybridisation (FISH) of 5S and 45S rDNA probes in four diploid and four tetraploid Phalaris species of both basic numbers. The data agree with a dysploid reduction from x = 7 to x = 6 as the result of reciprocal translocations between three chromosomes of an ancestor with a diploid chromosome complement of 2n = 14. We recognize three different genomes in the genus: (1) the exclusively Mediterranean genome A based on x = 6, (2) the cosmopolitan genome B based on x = 7 and (3) a genome C based on x = 7 and with a distribution in the Mediterranean and the Middle East. Both auto- and allopolyploidy of genomes B and C are suggested for the formation of tetraploids. The chromosomal divergence observed in Phalaris can be explained by the occurrence of dysploidy, the emergence of three different genomes, and the chromosome rearrangements accompanied by karyotype change and polyploidization. Mapping the recognized karyotypes on the existing phylogenetic tree suggests that genomes A and C are restricted to sections Phalaris and Bulbophalaris, respectively, while genome B occurs across all taxa with x = 7. PMID- 29462208 TI - Quantifying the fitness cost of HIV-1 drug resistance mutations through phylodynamics. AB - Drug resistant HIV is a major threat to the long-term efficacy of antiretroviral treatment. Around 10% of ART-naive patients in Europe are infected with drug resistant HIV type 1. Hence it is important to understand the dynamics of transmitted drug resistance evolution. Thanks to routinely performed drug resistance tests, HIV sequence data is increasingly available and can be used to reconstruct the phylogenetic relationship among viral lineages. In this study we employ a phylodynamic approach to quantify the fitness costs of major resistance mutations in the Swiss HIV cohort. The viral phylogeny reflects the transmission tree, which we model using stochastic birth-death-sampling processes with two types: hosts infected by a sensitive or resistant strain. This allows quantification of fitness cost as the ratio between transmission rates of hosts infected by drug resistant strains and transmission rates of hosts infected by drug sensitive strains. The resistance mutations 41L, 67N, 70R, 184V, 210W, 215D, 215S and 219Q (nRTI-related) and 103N, 108I, 138A, 181C, 190A (NNRTI-related) in the reverse trancriptase and the 90M mutation in the protease gene are included in this study. Among the considered resistance mutations, only the 90M mutation in the protease gene was found to have significantly higher fitness than the drug sensitive strains. The following mutations associated with resistance to reverse transcriptase inhibitors were found to be less fit than the sensitive strains: 67N, 70R, 184V, 219Q. The highest posterior density intervals of the transmission ratios for the remaining resistance mutations included in this study all included 1, suggesting that these mutations do not have a significant effect on viral transmissibility within the Swiss HIV cohort. These patterns are consistent with alternative measures of the fitness cost of resistance mutations. Overall, we have developed and validated a novel phylodynamic approach to estimate the transmission fitness cost of drug resistance mutations. PMID- 29462209 TI - Modulation of the colon cancer cell phenotype by pro-inflammatory macrophages: A preclinical model of surgery-associated inflammation and tumor recurrence. AB - Peritoneal infection after colorectal cancer surgery is associated with a higher rate of tumor relapse. We have recently proposed that soluble inflammatory factors released in response to a postoperative infection enhance tumor progression features in residual tumor cells. In an effort to set up models to study the mechanisms of residual tumor cell activation during surgery-associated inflammation, we have analyzed the phenotypic response of colon cancer cell lines to the paracrine effects of THP-1 and U937 differentiated human macrophages, which release an inflammatory medium characteristic of an innate immune response. The exposure of the colon cancer cell lines HT-29 and SW620 to conditioned media isolated from differentiated THP-1 and U937 macrophages induced a mesenchymal like phenotypic shift, involving the activation of in vitro invasiveness. The inflammatory media activated the beta-catenin/TCF4 transcriptional pathway and induced the expression of several mesenchymal (e.g., FN1 and VIM) and TCF4 target genes (e.g., MMP7, PTGS2, MET, and CCD1). Similarly, differential expression of some transcription factors involved in epithelial-to-mesenchymal transitions (i.e. ZEB1, SNAI1, and SNAI2) was variably observed in the colon cancer cell lines when exposed to the inflammatory media. THP-1 and U937 macrophages, which displayed characteristics of M1 differentiation, overexpressed some cytokines previously shown to be induced in colorectal cancer patients with increased rates of tumor recurrence associated with postoperative peritoneal infections, thus suggesting their pro-tumoral character. Therefore, the environment created by inflammatory M1 macrophages enhances features of epithelial-to-mesenchymal transition, and may be useful as a model to characterize pro-inflammatory cytokines as putative biomarkers of tumor recurrence risk. PMID- 29462210 TI - SNP markers tightly linked to root knot nematode resistance in grapevine (Vitis cinerea) identified by a genotyping-by-sequencing approach followed by Sequenom MassARRAY validation. AB - Plant parasitic nematodes, including root knot nematode Meloidogyne species, cause extensive damage to agriculture and horticultural crops. As Vitis vinifera cultivars are susceptible to root knot nematode parasitism, rootstocks resistant to these soil pests provide a sustainable approach to maintain grapevine production. Currently, most of the commercially available root knot nematode resistant rootstocks are highly vigorous and take up excess potassium, which reduces wine quality. As a result, there is a pressing need to breed new root knot nematode resistant rootstocks, which have no impact on wine quality. To develop molecular markers that predict root knot nematode resistance for marker assisted breeding, a genetic approach was employed to identify a root knot nematode resistance locus in grapevine. To this end, a Meloidogyne javanica resistant Vitis cinerea accession was crossed to a susceptible Vitis vinifera cultivar Riesling and results from screening the F1 individuals support a model that root knot nematode resistance, is conferred by a single dominant allele, referred as MELOIDOGYNE JAVANICA RESISTANCE1 (MJR1). Further, MJR1 resistance appears to be mediated by a hypersensitive response that occurs in the root apical meristem. Single nucleotide polymorphisms (SNPs) were identified using genotyping-by-sequencing and results from association and genetic mapping identified the MJR1 locus, which is located on chromosome 18 in the Vitis cinerea accession. Validation of the SNPs linked to the MJR1 locus using a Sequenom MassARRAY platform found that only 50% could be validated. The validated SNPs that flank and co-segregate with the MJR1 locus can be used for marker-assisted selection for Meloidogyne javanica resistance in grapevine. PMID- 29462211 TI - Lung cancer and socioeconomic status in a pooled analysis of case-control studies. AB - BACKGROUND: An association between low socioeconomic status (SES) and lung cancer has been observed in several studies, but often without adequate control for smoking behavior. We studied the association between lung cancer and occupationally derived SES, using data from the international pooled SYNERGY study. METHODS: Twelve case-control studies from Europe and Canada were included in the analysis. Based on occupational histories of study participants we measured SES using the International Socio-Economic Index of Occupational Status (ISEI) and the European Socio-economic Classification (ESeC). We divided the ISEI range into categories, using various criteria. Stratifying by gender, we calculated odds ratios (OR) and 95% confidence intervals (CI) by unconditional logistic regression, adjusting for age, study, and smoking behavior. We conducted analyses by histological subtypes of lung cancer and subgroup analyses by study region, birth cohort, education and occupational exposure to known lung carcinogens. RESULTS: The analysis dataset included 17,021 cases and 20,885 controls. There was a strong elevated OR between lung cancer and low SES, which was attenuated substantially after adjustment for smoking, however a social gradient persisted. SES differences in lung cancer risk were higher among men (lowest vs. highest SES category: ISEI OR 1.84 (95% CI 1.61-2.09); ESeC OR 1.53 (95% CI 1.44-1.63)), than among women (lowest vs. highest SES category: ISEI OR 1.54 (95% CI 1.20-1.98); ESeC OR 1.34 (95% CI 1.19-1.52)). CONCLUSION: SES remained a risk factor for lung cancer after adjustment for smoking behavior. PMID- 29462212 TI - Epstein-Barr virus nuclear antigen EBNA-LP is essential for transforming naive B cells, and facilitates recruitment of transcription factors to the viral genome. AB - The Epstein-Barr virus (EBV) nuclear antigen leader protein (EBNA-LP) is the first viral latency-associated protein produced after EBV infection of resting B cells. Its role in B cell transformation is poorly defined, but it has been reported to enhance gene activation by the EBV protein EBNA2 in vitro. We generated EBNA-LP knockout (LPKO) EBVs containing a STOP codon within each repeat unit of internal repeat 1 (IR1). EBNA-LP-mutant EBVs established lymphoblastoid cell lines (LCLs) from adult B cells at reduced efficiency, but not from umbilical cord B cells, which died approximately two weeks after infection. Adult B cells only established EBNA-LP-null LCLs with a memory (CD27+) phenotype. Quantitative PCR analysis of virus gene expression after infection identified both an altered ratio of the EBNA genes, and a dramatic reduction in transcript levels of both EBNA2-regulated virus genes (LMP1 and LMP2) and the EBNA2 independent EBER genes in the first 2 weeks. By 30 days post infection, LPKO transcription was the same as wild-type EBV. In contrast, EBNA2-regulated cellular genes were induced efficiently by LPKO viruses. Chromatin immunoprecipitation revealed that EBNA2 and the host transcription factors EBF1 and RBPJ were delayed in their recruitment to all viral latency promoters tested, whereas these same factors were recruited efficiently to several host genes, which exhibited increased EBNA2 recruitment. We conclude that EBNA-LP does not simply co-operate with EBNA2 in activating gene transcription, but rather facilitates the recruitment of several transcription factors to the viral genome, to enable transcription of virus latency genes. Additionally, our findings suggest that EBNA-LP is essential for the survival of EBV-infected naive B cells. PMID- 29462213 TI - Early detection of pancreatic cancer in mouse models using a novel antibody, TAB004. AB - Pancreatic ductal adenocarcinoma (PDA) is the fourth-leading cause of cancer death in the United States with a 5-year overall survival rate of 8% for all stages combined. But this decreases to 3% for the majority of patients that present with stage IV PDA at time of diagnosis. The lack of distinct early symptoms for PDA is one of the primary reasons for the late diagnosis. Common symptoms like weight loss, abdominal and back pains, and jaundice are often mistaken for symptoms of other issues and do not appear until the cancer has progressed to a late stage. Thus the development of novel imaging platforms for PDA is crucial for the early detection of the disease. MUC1 is a tumor-associated antigen (tMUC1) expressed on 80% of PDA. The goal of this study was to determine the targeting and detection capabilities of a tMUC1 specific antibody, TAB004. TAB004 antibody conjugated to a near infrared fluorescent probe was injected intraperitoneally into immune competent orthotopic and spontaneous models of PDA. Results show that fluorophore conjugated TAB004 specifically targets a) 1 week old small tumor in the pancreas in an orthotopic PDA model and b) very early pre neoplastic lesions (PanIN lesions) that develop in the spontaneous PDA model before progression to adenocarcinoma. Thus, TAB004 is a promising antibody to deliver imaging agents directly to the pancreatic tumor microenvironment, significantly affecting early detection of PDA. PMID- 29462214 TI - A phytosociological analysis and description of wetland vegetation and ecological factors associated with locations of high mortality for the 2010-11 Rift Valley fever outbreak in South Africa. AB - Rift Valley fever (RVF) is endemic in Africa and parts of the Middle East. It is an emerging zoonotic disease threat to veterinary and public health. Outbreaks of the disease have severe socio-economic impacts. RVF virus emergence is closely associated with specific endorheic wetlands that are utilized by the virus' mosquito vectors. Limited botanical vegetation surveys had been published with regard to RVF virus (RVFV) ecology. We report on a phytosociological classification, analysis and description of wetland vegetation and related abiotic parameters to elucidate factors possibly associated with the 2010-2011 RVFV disease outbreak in South Africa. The study sites were located in the western Free State and adjacent Northern Cape covering an area of ~40,000 km2 with wetlands associated with high RVF mortality rates in livestock. Other study sites included areas where no RVF activity was reported during the 2010-11 RVF outbreak. A total of 129 plots (30 m2) were selected where a visible difference could be seen in the wetland and upland vegetation. The Braun-Blanquet method was used for plant sampling. Classification was done using modified Two-Way Indicator Species Analysis. The vegetation analysis resulted in the identification of eight plant communities, seven sub-communities and two variants. Indirect ordination was carried out using CANOCO to investigate the relationship between species and wetland ecology. The study also identified 5 categories of wetlands including anthropogenic wetlands. Locations of reported RVF cases overlapped sites characterized by high clay-content soils and specific wetland vegetation. These findings indicate ecological and environmental parameters that represent preferred breeding habitat for RVFV competent mosquito vectors. PMID- 29462215 TI - Robson 10-groups classification system to access C-section in two public hospitals of the Federal District/Brazil. AB - BACKGROUND: The global increase in C-section rates is real. In Brazil, these indices correspond to 58.94% in the Midwest region and 52.77% in the Federal District. OBJECTIVE: To evaluate the C-section rates and identify the groups with the greatest risk at two reference hospitals in the public network of Federal District/Brazil, using 10-Group Robson System. METHOD: A cross-sectional study of 6579 births assisted at the Hospital A (HA) and the Hospital B (HB) during 2013. The C-section rates in each group and its respective contribution to the total hospital C-sections was compared between HA and HB. To this, was used the proportion difference test (similar to chi-square test), with RR and 95% CI, and the logistic regression analysis (OR; 95% CI) among the groups with higher C section/total C-section. The significance limit of p < 0.05 was defined for all tests. RESULTS: The C-section rates were 50.8% at the HA and 42.3% at the HB, with 1.20 RR (95%CI = 1.13-1.28) at the HA. The highest rates were observed in Robson groups G5, G1, and G2. At the HA, G1 had a 21.5% C-section rate, which was greater than at the HB (13.8%; p < 0.05); the cesarean rates for groups G2 and G5 were higher at the HB (respectively, 18.6 and 38.1%) than at the HA (14.8 and 32.5%, respectively; p < 0.05). CONCLUSION: These results point out specific goals to be achieved in order to reduce abusive cesarean rates in both A and B hospitals, especially in the primigravida and in those with previous C-section.

AB - Changes in gene expression can help reveal the mechanisms of disease processes and the mode of action for toxicities and adverse effects on cellular responses induced by exposures to chemicals, drugs and environment agents. The U.S. Tox21 Federal collaboration, which currently quantifies the biological effects of nearly 10,000 chemicals via quantitative high-throughput screening(qHTS) in in vitro model systems, is now making an effort to incorporate gene expression profiling into the existing battery of assays. Whole transcriptome analyses performed on large numbers of samples using microarrays or RNA-Seq is currently cost-prohibitive. Accordingly, the Tox21 Program is pursuing a high-throughput transcriptomics (HTT) method that focuses on the targeted detection of gene expression for a carefully selected subset of the transcriptome that potentially can reduce the cost by a factor of 10-fold, allowing for the analysis of larger numbers of samples. To identify the optimal transcriptome subset, genes were sought that are (1) representative of the highly diverse biological space, (2) capable of serving as a proxy for expression changes in unmeasured genes, and (3) sufficient to provide coverage of well described biological pathways. A hybrid method for gene selection is presented herein that combines data-driven and knowledge-driven concepts into one cohesive method. Our approach is modular, applicable to any species, and facilitates a robust, quantitative evaluation of performance. In particular, we were able to perform gene selection such that the resulting set of "sentinel genes" adequately represents all known canonical pathways from Molecular Signature Database (MSigDB v4.0) and can be used to infer expression changes for the remainder of the transcriptome. The resulting computational model allowed us to choose a purely data-driven subset of 1500 sentinel genes, referred to as the S1500 set, which was then augmented using a knowledge-driven selection of additional genes to create the final S1500+ gene set. Our results indicate that the sentinel genes selected can be used to accurately predict pathway perturbations and biological relationships for samples under study.

PMID- 29462217 TI - A flocking algorithm for multi-agent systems with connectivity preservation under hybrid metric-topological interactions. AB - In this paper, we propose a connectivity-preserving flocking algorithm for multi agent systems in which the neighbor set of each agent is determined by the hybrid metric-topological distance so that the interaction topology can be represented as the range-limited Delaunay graph, which combines the properties of the commonly used disk graph and Delaunay graph. As a result, the proposed flocking algorithm has the following advantages over the existing ones. First, range limited Delaunay graph is sparser than the disk graph so that the information exchange among agents is reduced significantly. Second, some links irrelevant to the connectivity can be dynamically deleted during the evolution of the system. Thus, the proposed flocking algorithm is more flexible than existing algorithms, where links are not allowed to be disconnected once they are created. Finally, the multi-agent system spontaneously generates a regular quasi-lattice formation without imposing the constraint on the ratio of the sensing range of the agent to the desired distance between two adjacent agents. With the interaction topology induced by the hybrid distance, the proposed flocking algorithm can still be implemented in a distributed manner. We prove that the proposed flocking algorithm can steer the multi-agent system to a stable flocking motion, provided the initial interaction topology of multi-agent systems is connected and the hysteresis in link addition is smaller than a derived upper bound. The correctness and effectiveness of the proposed algorithm are verified by extensive numerical simulations, where the flocking algorithms based on the disk and Delaunay graph are compared.

AB - BACKGROUND: Atopic dermatitis (AD) is primarily treated with topical therapies, systemic immunosuppressants, or adjunctive therapies. OBJECTIVE: As novel treatment approaches for AD emerge, we characterize AD treatment and examine trends in treatment over time. METHODS: Visits for AD were identified in the 2003 2012 National Ambulatory Medical Care Survey (NAMCS). We identified topical corticosteroids (TCS), antibiotics (Abx), antihistamines (AH), topical calcineurin inhibitors (TCI), and systemic immunosuppressants (SI) prescribed at AD visits. RESULTS: There were 990,000 annual visits for AD from 2003-2012 (3.2 visits/1000 people/year). TCS were the most frequently used medication (59% of visits). Topical calcineurin inhibitors (TCI) were the second most prescribed medication for AD among dermatologists (23% of visits), while antihistamines were second among all other physicians (16-44% of visits). Unlike other medications, use of TCIs decreased over time. LIMITATIONS: The NAMCS does not follow individual patients over time. CONCLUSIONS: TCI use has been decreasing. New topical AD treatments may provide an alternative to TCS, better treatment outcomes for moderate-to-severe atopic dermatitis, and an alternative to systemic antihistamines whose efficacy in AD is unproven and whose general use in AD management is discouraged by the American Academy of Dermatology.

AB - BACKGROUND: Information is limited on the use of vismodegib for treatment of advanced basal cell carcinoma beyond the setting of clinical trials. OBJECTIVE: To investigate the treatment patterns and characteristics of patients treated with vismodegib in clinical practice. METHODS: A longitudinal, retrospective cohort study was undertaken using data from a US commercial insurance claims (Truven Health Analytics MarketScan) database. Eligible patients were >=18 years of age, with >=1 claim for vismodegib from January 2012 to December 2015. RESULTS: A total of 321 patients were included in the analysis. Approximately 20% of the patients took 1 or more treatment breaks of >= 30 days each before treatment discontinuation. Median duration of vismodegib treatment before the first treatment break and discontinuation was 4.0 and 5.5 months, respectively. Older age ( > 65 years) and absence of Gorlin syndrome were associated with increased risk for treatment interruption or discontinuation. Overall, 47% and 36% of patients underwent surgery or radiotherapy within the 6 months before and after vismodegib initiation, respectively. CONCLUSIONS: Real-world evidence indicates that vismodegib is being used in clinical practice as part of combination treatment strategies. J Drugs Dermatol. 2018;17(2):143-148. PMID- 29462222 TI - Cross-Sectional Survey of the Burden of Illness of Rosacea by Erythema Severity. AB - Rosacea is a chronic skin condition characterized by persistent central facial erythema. To explore the burden of illness of rosacea in US adults, a cross sectional web-based survey was conducted. Participants answered questions on sociodemographics, clinical characteristics, bothersome symptoms, coping and avoidance behaviors, self-perceptions, and health care resource utilization, and completed 2 quality of life instruments, the 21-item rosacea-specific quality of life questionnaire (RosaQoL) and the 36-item Short Form Health Survey (SF-36). This paper reports the data from the 409 respondents with erythematotelangiectatic rosacea (ETR), analyzed by erythema severity. Mean age was 53.1 years; mild, moderate, or severe erythema was reported by 63.6%, 32.0%, and 4.4% of participants, respectively. Blushing/flushing and bumps/pustules were the most bothersome symptoms across severity subgroups. Participants in all subgroups coped with rosacea by applying make-up and managing their stress and anxiety, and tried to prevent rosacea flares by avoiding sun exposure, specific skin care products, and other triggers. Self-perceptions differed by severity subgroup: satisfaction with facial appearance significantly decreased, and worrying about how people will react and feelings of unattractiveness to others significantly increased, with greater erythema severity (all P less than 0.01). Treatment or assessment of rosacea was sought by 20% of participants in the past 3 months, most commonly from a dermatologist. Metronidazole was the most frequently prescribed topical product across severity subgroups, whereas doxycycline and other oral antibiotics were prescribed most frequently in the severe erythema subgroup. RosaQoL emotional domain scores increased with erythema severity (P equals 0.0035), but none of the SF-36 domain scores differed significantly by erythema severity. These results demonstrate that rosacea is associated with a substantial burden of illness that spans all levels of erythema severity in patients with ETR. Feelings of unattractiveness and the adverse impact of rosacea on emotional quality of life increased with erythema severity. J Drugs Dermatol. 2018;17(2):150-158. PMID- 29462223 TI - Efficacy, Safety, and Tolerability of Topical Dapsone Gel, 7.5% for Treatment of Acne Vulgaris by Fitzpatrick Skin Phototype. AB - BACKGROUND: Acne vulgaris (acne) is prevalent in individuals with skin of color, often with more frequent sequelae than in patients with lighter skin color. It is important to determine if there are also differences in response to medications. OBJECTIVE: This study evaluated the efficacy and tolerability of once-daily dapsone gel, 7.5% in patients with acne, stratified by Fitzpatrick skin phototype. METHODS: Data were pooled from 2 identically designed, phase 3, randomized, double-blind, vehicle-controlled studies in patients aged 12 years and older with moderate acne. Patients applied dapsone gel, 7.5% or vehicle once daily for 12 weeks. Efficacy was evaluated using the Global Acne Assessment Score (GAAS), lesion counts, and Acne Symptom and Impact Scale (ASIS); adverse events (AEs) and tolerability were also assessed. RESULTS: This analysis included 2216 patients with skin phototypes I-III and 2111 with types IV-VI. Dapsone gel, 7.5% significantly improved acne severity versus vehicle in both skin phototype subgroups, as determined by the percentage of patients with at least a 1-grade improvement in GAAS and mean change from baseline in GAAS (both, P less than .0001) at week 12 versus baseline. Dapsone gel, 7.5% significantly reduced inflammatory, comedonal, and total lesions in skin phototypes I-III (P less than .001) and IV-VI (P less than equal to .01) versus vehicle. Improvements in inflammatory lesions occurred first, with generally similar patterns of improvement seen over time in GAAS, comedonal lesions, and ASIS domains. The incidence of AEs was similar in both skin phototype subgroups and between study medications. Local scaling, erythema, stinging/burning, and dryness were rated "none" by most patients in both treatment groups and skin phototype subgroups. CONCLUSION: Once-daily dapsone gel, 7.5% was effective, safe, and well tolerated in patients with all skin phototypes who were treated for moderate acne. J Drugs Dermatol. 2018;17(2):160-167. PMID- 29462224 TI - Planimetric Post-hoc Analysis of Women With Onychomycosis from Tavaborole 5% Phase III Studies: Evidence of Greater Improvements in Patients With >50% Baseline Infection. AB - Women with onychomycosis may suffer more effects on their quality of life than men. There is limited female-specific data on the treatment of onychomycosis. Tavaborole is a topical treatment option for onychomycosis. This post-hoc study evaluated the nail plates of women using data from the tavaborole 5% Phase III studies at baseline and end of study for the areas of healthy nail and infected nail. Over 52 weeks (48-week treatment, 4-week follow up), women treated with tavaborole had an average 32% increase in healthy nail and 21% decrease in infected nail. Patients with baseline infection involving >50% of the nail plate had an average increase in percentage of unaffected nail surface area of 81% and a corresponding 51% decrease in infected nail. These analyses suggest that patients with the greatest toenail involvement at baseline had greater overall improvements than those who were less affected. This evaluation provides additional clinical guidance for treating women with onychomycosis using tavaborole. J Drugs Dermatol. 2018;17(2):168-172. PMID- 29462225 TI - Is Severity of Disease a Prognostic Factor for Cure Following Treatment of Onychomycosis? AB - BACKGROUND: Onychomycosis is a common disease that remains a difficult disorder to treat despite the introduction of new topical agents; and not all patients are cured. Clinical experience leads us to suggest a number of host-related factors can affect the chance of cure, but studies supporting these observations are currently lacking. Although many studies, particularly on topical agents, rely on severity classification when selecting patients for inclusion, a pilot study was unable to demonstrate any prognostic value of the extension of nail involvement. In addition, no universal severity classification exists, and most studies do not report prognostic factors. OBJECTIVE: To investigate the efficacy of efinaconazole topical solution, 10% in patients with mild-to-moderate onychomycosis and determine the impact of baseline severity on treatment outcome. METHODS: Post hoc pooled analysis of two identical, multicenter, randomized, double-blind, vehicle-controlled studies in 1655 patients aged 18-70 years with a clinical and mycological diagnosis of mild-to-moderate dermatophyte toenail onychomycosis (20-50% clinical involvement). Patients were randomized (3:1) to efinaconazole 10% solution or vehicle, once-daily for 48 weeks, with 4-week post treatment follow-up. Efficacy criteria included clear nail (0% target nail plate involvement), almost clear nail (<=5% target nail plate involvement), and clinical treatment success (<=10% target nail plate involvement) at week 52. For the post hoc analysis, patients were classified as mild (20%-29% nail involvement), moderate (30%-39%), and moderately severe (40%-50%) at baseline. RESULTS: Overall, 25%, 23%, and 52% of patients had mild, moderate, or moderately severe disease at baseline. Baseline nail involvement did not appear to predict treatment outcomes. The proportion of patients with mild disease who had a clear nail progressively reduced by week 36 (58%) and week 48 (41%), and even further by week 52 (37%). Of the 237 patients treated with efinaconazole who were 'clear' at week 52, 37%, 24%, and 39% had mild, moderate or moderately severe disease respectively at baseline. The majority of patients (N=634) saw at least a 50% improvement in their target toenail by week 52. Almost half of these patients (N=312, 49.2%) were moderately severe at baseline. CONCLUSIONS: This post hoc analysis supports previous data showing good efficacy of efinaconazole in mild onychomycosis. The relative contribution to overall efficacy results at week 52 of patients with moderate or moderately severe disease was unexpected for a topical therapy, and warrants further study, especially as they represent the majority of patients enrolled in the two studies. It is possible that comparable efficacy can be achieved in these more severe patients with longer treatment courses, or follow-up. J Drugs Dermatol. 2018;17(2):175-178. PMID- 29462226 TI - Increased Prevalence of Cancer in Adult Patients With Psoriasis in the United States: A Claims Based Analysis. AB - BACKGROUND: Psoriasis (Ps) is a chronic inflammatory immune-mediated skin disease that has been identified as a risk factor for various conditions including neoplasms. OBJECTIVE: To compare prevalence of cancer between Ps and Ps-free patients. METHODS: Adult patients continuously enrolled for >=12 months (>=1 month in 2014) were selected from a large United States (US) claims database (Q1:2010-Q4:2014) and classified as Ps patients (>=2 Ps diagnoses; International Classification of Diseases 9th Revision, [ICD-9] code: 696.1x) and Ps-free patients (no Ps diagnosis). Patients were exactly matched (1:1) based on age, gender, state of residence, and insurance plan type. Prevalence of cancer was compared between cohorts over patients' last 12 months of continuous healthcare plan enrollment using logistic-regression models. RESULTS: A total of 179,066 pairs of Ps and Ps-free patients were selected. Median age was 54.0 years, 51.7% were females. Prevalence of cancer was higher among Ps patients for any type of neoplasms (OR [95% confidence interval (CI)]=1.86 [1.83; 1.89]), malignant neoplasms (OR [95% CI]=1.53 [1.49;1.57]), as well as malignant skin neoplasms (OR [95% CI]=1.87 [1.79; 1.95]), lymphatic and hematopoietic tissues (OR [95% CI]=1.70 [1.57;1.84]), genital (OR [95% CI]=1.33 [1.26;1.41]), breast (OR [95% CI]=1.32 [1.24;1.40]), digestive organs and peritoneum (OR [95% CI]=1.24 [1.13;1.35]), urinary organs (OR [95% CI]=1.49 [1.36;1.64]), respiratory and intrathoracic organs (OR [95% CI]=1.30 [1.17;1.44]), and metastatic cancer (OR [95% CI]=1.14 [1.06;1.24]), all P less than 0.01. LIMITATIONS: Impact of Ps severity could not be assessed. CONCLUSION: Ps patients had a higher prevalence of cancer than Ps-free patients. J Drugs Dermatol. 2018;17(2):180-186. PMID- 29462227 TI - Prevalence of Psoriasis in Children and Adolescents in the United States: A Claims-Based Analysis. AB - IMPORTANCE: While psoriasis (Ps) is mainly characterized as an adult disease, it can also develop during childhood. However, prevalence estimates of pediatric psoriasis in the United States (US) are lacking. OBJECTIVE: To assess the 2015 annual prevalence of Ps and moderate-to-severe Ps in pediatric individuals in the US. DESIGN: This is a retrospective study based on a large administrative insurance claims database in the US. SETTING: Data were extracted from the Truven Health Analytics MarketScan(r) Commercial Claims and Encounters database, which covers over 60 million individuals with employer-provided health insurance across the US. PARTICIPANTS: Over 4.3 million of individuals continuously enrolled in their healthcare plan in 2015 and under 18 years of age were included in the study. Intervention(s) for Clinical Trials or Exposure(s) for Observational Studies: Not applicable. Main Outcome(s) and Measure(s): Ps was defined based on medical claims with a diagnosis of Ps (ICD-9-CM: 696.1); moderate-to-severe Ps was defined based on medical or pharmacy claims for a systemic treatment (biologic, conventional systemic, or phototherapy) for Ps. Overall and age- and gender-stratified prevalence was estimated for both Ps and moderate-to-severe Ps. RESULTS: The prevalence of Ps was estimated at 128 cases per 100,000 individuals (95% CI: 124-131), that of moderate-to-severe Ps at 16 cases per 100,000 individuals (95% CI: 15-17) in 2015. For both Ps and moderate-to-severe Ps, prevalence estimates were numerically higher in females than in males (146 per 100,000 vs. 110 per 100,000 and 17 per 100,000 vs. 15 per 100,000) and increased with age, ranging from 30 per 100,000 in the 0-3 year old group to 205 per 100,000 in the 12-17 year old group. CONCLUSION AND RELEVANCE: This study provides robust estimates of the prevalence of pediatric Ps that can inform decisions pertaining to the management of pediatric patients with Ps.

AB - INTRODUCTION: The surgeon's role in the follow-up of pathologic stage I and II melanoma patients has traditionally been minimal. Melanoma genetic expression profile (GEP) testing provides binary risk assessment (Class 1-low risk, Class 2 high risk), which can assist in predicting metastasis and formulating appropriate follow up. We sought to determine the impact of GEP results on the management of clinically node negative cutaneous melanoma patients staged with sentinel lymph node biopsy (SLNB). METHODS: A retrospective review of prospectively gathered data consisting of patients seen from September 2015 - August 2016 was performed to determine whether GEP class influenced follow-up recommendations. Patients were stratified into four groups based on recommended follow-up plan: Dermatology alone, Surgical Oncology, Surgical Oncology with recommendation for adjuvant clinical trial, or Medical and Surgical Oncology. RESULTS: Of ninety-one patients, 38 were pathologically stage I, 42 stage II, 10 stage III, and 1 stage IV. Combining all stages, GEP Class 1 patients were more likely to be followed by Dermatology alone and less like to be followed by Surgical Oncology with recommendation for adjuvant trial compared to Class 2 patients (P less than 0.001). Among stage 1 patients, Class 1 were more likely to follow up with Dermatology alone compared to Class 2 patients (82 vs. 0%; P less than 0.001). Among stage II patients, GEP Class 1 were more likely to follow up with Dermatology alone (21 vs 0%) and more Class 2 patients followed up with surgery and recommendations for adjuvant trial (36 vs 64%; P less than 0.05). There was no difference in follow up for stage III patients based on the GEP results (P=0.76). CONCLUSION: GEP results were significantly associated with the management of stage I-II melanoma patients after staging with SLNB. For node negative patients, Class 2 results led to more aggressive follow up and management. J Drugs Dermatol. 2018;17(2):196-199. PMID- 29462229 TI - Safety and Tolerability of Ixekizumab: Integrated Analysis of Injection-Site Reactions from 11 Clinical Trials. AB -

BACKGROUND: Injection-site reactions (ISRs) are reported with biologic therapies. The objective of this study was to comprehensively characterize ISRs among moderate-to-severe psoriasis patients treated with ixekizumab, a high affinity monoclonal antibody that selectively targets interleukin (IL)-17A.

METHODS: ISRs are presented from UNCOVER-1, UNCOVER-2, and UNCOVER-3 (12 weeks) and all ixekizumab-exposed patients in 11 controlled and uncontrolled trials (156 weeks).

RESULTS: At week 12, reported ISR frequency with 80 mg ixekizumab every 2 weeks (IXE Q2W, 16.8%) was comparable with etanercept twice weekly (16.4%); both were significantly higher than placebo (3.3%). With IXE Q2W, ISRs were mild (12.3%), moderate (3.9%), or severe (0.7%), typically reported in the first 2 weeks (median onset, 6.6 days), and most commonly characterized as nonspecified, erythema, and pain. Generally, erythema onset was delayed, whereas pain occurred around drug administration. Discontinuation from ixekizumab due to ISRs (0.4%) occurred in the first 12 weeks. After 2 weeks, ISR frequency decreased and remained stable (<=4.2%) through week 156. No ISR-related serious adverse events were reported in ixekizumab-treated patients. ISR data were solicited if patients reported injection-associated events. Since nonspecified ISR was the most commonly reported term, specific types might be underreported.

CONCLUSIONS: ISRs have been reported with ixekizumab during clinical trials. These reactions are typically tolerable, manageable, and decrease over time.

AB - BACKGROUND: Oxymetazoline cream 1.0% is FDA-approved for the topical treatment of persistent facial erythema associated with rosacea in adults. This phase 2, multicenter, randomized, double-blind, parallel-group study assessed the pharmacokinetics, safety, and tolerability of oxymetazoline in patients with moderate to severe erythema associated with rosacea. METHODS: Eligible patients were randomized to 1 of 8 treatment groups (oxymetazoline cream 0.5%, 1.0%, or 1.5% or vehicle applied topically either once or twice daily for 28 days). Pharmacokinetic analyses were conducted in patients receiving oxymetazoline. Plasma samples for pharmacokinetic assessments were collected prior to dosing and 6 times postdose on days 1 and 28. RESULTS: A total of 356 patients were included in the safety population (oxymetazoline, n=268; vehicle, n=88). Thirty patients (11.2%) in the oxymetazoline group reported treatment-related treatment-emergent adverse events, most of which were mild to moderate application-site reactions. Oxymetazoline, at all concentrations, was generally safe and well tolerated. Mean maximum observed plasma concentrations were <=115 pg/mL across all groups; the highest mean values for area under the plasma concentration-time curve from time 0 to 24 hours following once- and twice-daily administration of oxymetazoline 1.5% were 1680 pg*h/mL and 2660 pg*h/mL, respectively. Systemic exposure to oxymetazoline increased dose proportionally with once- and twice-daily administration. CONCLUSION: These findings support the use of oxymetazoline for the treatment of persistent facial erythema associated with rosacea. J Drugs Dermatol. 2018;17(2):213-220. PMID- 29462231 TI - Efficacy and Safety of Apremilast in Systemic- and Biologic-Naive Patients With Moderate Plaque Psoriasis: 52-Week Results of UNVEIL. AB -

BACKGROUND: Many patients with moderate plaque psoriasis are undertreated despite broadening treatment options. In the phase IV UNVEIL study, oral apremilast demonstrated efficacy and safety in systemic-naive patients with chronic moderate plaque psoriasis with lower psoriasis-involved body surface area (BSA; 5%-10%) during the 16-week, double-blind, placebo-controlled phase. We describe efficacy and safety of apremilast in this population through week 52 in UNVEIL.

METHODS: Patients with moderate plaque psoriasis (BSA 5%-10%; static Physician's Global Assessment [sPGA] score of 3 [moderate]) and naive to systemic therapies for psoriasis were randomized (2:1) to receive apremilast 30 mg twice daily or placebo for 16 weeks. At week 16, patients continued on apremilast (apremilast/apremilast) or were switched from placebo to apremilast (placebo/apremilast) through week 52 (open-label apremilast treatment phase). Efficacy assessments included the product of sPGA and BSA (PGAxBSA) (mean percentage change from baseline; >=75% reduction from baseline [PGAxBSA-75]), sPGA response (achievement of score of 0 [clear] or 1 [almost clear]), and the Dermatology Life Quality Index (DLQI; mean change from baseline).

RESULTS: A total of 136 patients completed the 52-week analysis period (placebo/apremilast, n=50/64; apremilast/apremilast, n=86/121). At week 52, improvements in all efficacy end points observed at week 16 were maintained in the apremilast/apremilast group (mean percentage change from baseline in PGAxBSA: -55.5%; PGAxBSA-75: 42.1%; sPGA response: 33.1%; mean change from baseline in DLQI score: -4.4); similar improvements emerged in the placebo/apremilast group after switching to apremilast. The most common adverse events (>=5% of patients) through week 52 were diarrhea (28.0%), nausea (19.0%), headache (15.2%), nasopharyngitis (10.4%), upper respiratory tract infection (7.1%), vomiting (5.7%), and decreased appetite (5.2%).

CONCLUSIONS: Apremilast was effective in systemic-naive patients with moderate plaque psoriasis with BSA 5% 10%; efficacy was sustained through week 52. No new safety signals emerged with continued apremilast exposure.

AB - BACKGROUND: Tinea pedis is the most common dermatophyte infection. Treatment is critical to alleviate pruritic symptoms, to reduce the risk for secondary bacterial infection, and to limit the spread of infection to other body sites or other individuals. The objective of this study was to compare the abilities of econazole nitrate topical foam, 1% and ketoconazole cream (2%) to reduce pruritus, thus improving quality of life, and to determine patient preference for the foam product versus the cream product in patients with interdigital tinea pedis. STUDY DESIGN: A single-center, investigator-blinded, observational pilot study was conducted to compare econazole nitrate topical foam (1%) to ketoconazole cream (2%). In this split-body study, 20 subjects received both econazole nitrate topical foam and ketoconazole cream and applied the medications daily to either the right or left foot for 14 days. Improvements in patient quality of life (pruritus) and patient preference were measured using the pruritus visual analog scale (VAS), Skindex-16, and patient preference questionnaires. RESULTS: Nineteen subjects completed the study and one subject was lost to follow-up. Reductions in VAS scores of econazole nitrate topical foam were significantly greater than those of ketoconazole cream, indicating the superiority of the econazole nitrate foam in reducing pruritus. Skindex-16 data showed significant reductions in total scores and individual domains, including patient symptom, emotional, and functional domains, by the final visit. Since each subject received both medications the questionnaire was not medication specific. Responses to patient preference questionnaires showed that econazole nitrate topical foam,1% was rated as "good" or "excellent" in all measures assessed. One adverse event was noted. CONCLUSION: In patients with interdigital tinea pedis, application of econazole nitrate topical foam 1% twice daily for two weeks was clinically effective and significantly superior to ketoconazole cream 2% in reducing pruritus.

AB - Blastomycosis-like pyoderma (BLP) is a rare reactive skin disease that is most commonly caused by bacterial infection. Herein we present a case of BLP arising in lichen planus, a chronic inflammatory disease. We propose Wolf's isotopic response, or the appearance of a new skin disease at the site of an existing and unrelated disease, as the underlying molecular mechanism responsible for this unusual physical presentation. It is important that clinicians recognize atypical morphologies such as BLP, which mimics squamous cell carcinoma both clinically and pathologically. These similarities highlight the need for a tissue diagnosis to identify infectious etiologies and rule out malignancy when BLP is suspected. J Drugs Dermatol. 2018;17(2):233-235.

AB - Fifty years have passed since the findings of capacitation and acrosome reaction. These discoveries and the extensive effort of researchers led to the success of in vitro fertilization, which has become a top choice for patients at infertility clinics today. The effort to understand the mechanism of fertilization is ongoing, but the small number of eggs and similarly small quantity of spermatozoa continue to hinder biochemical experiments. The emergence of transgenic animals and gene disruption techniques has had a significant effect on fertilization research. Factors considered important in the early years were shown not to be essential and were replaced by newly found proteins. However, there is much about sperm-egg interaction which remains to be learned before we can outline the mechanism of fertilization. In fact, our understanding of sperm-egg interaction is entering a new stage. Progress in transgenic spermatozoa helped us to observe the behavior of spermatozoa in vivo and/or at the moment of sperm-egg fusion. These advancements are discussed together with the paradigm-shifting research in related fields to help us picture the direction which fertilization research may take in the future. PMID- 29462235 TI - Quality Improvement After Multiple Fatal Transfusion-Transmitted Bacterial Infections. AB - Objectives: Transfusion-transmitted bacterial infection (TTBI) from platelet components is likely underrecognized and can be fatal. Twenty-four-hour prospective culture was felt to be insufficiently preventive after multiple TTBIs occurred and strategies to improve safety were sought. Methods: Two fatal and one severe TTBIs occurred from a split-apheresis platelet donation contaminated with Klebsiella pneumoniae. Improvement opportunities were identified and corrective and preventive action (CAPA) followed. Results: To mitigate bacterial contamination and improve detection sensitivity, additional prospective culture 48 hours postcollection was implemented. Since implementation, secondary cultures have caught two true positives (0.01%) missed by 24-hour culture. Bacterial testing at issue and pathogen reduction were later implemented as an added layer of safety. Conclusion: While rare, TTBI is a prominent cause of morbidity and mortality from contaminated platelets. The approach to CAPA presented here may lower the risk of future transfusion-transmitted infections but must be weighed against potential added costs. PMID- 29462237 TI - LS-align: an atom-level, flexible ligand structural alignment algorithm for high throughput virtual screening. AB - Motivation: Sequence-order independent structural comparison, also called structural alignment, of small ligand molecules is often needed for computer aided virtual drug screening. Although many ligand structure alignment programs are proposed, most of them build the alignments based on rigid-body shape comparison which cannot provide atom-specific alignment information nor allow structural variation; both abilities are critical to efficient high-throughput virtual screening. Results: We propose a novel ligand comparison algorithm, LS align, to generate fast and accurate atom-level structural alignments of ligand molecules, through an iterative heuristic search of the target function that combines inter-atom distance with mass and chemical bond comparisons. LS-align contains two modules of Rigid-LS-align and Flexi-LS-align, designed for rigid body and flexible alignments, respectively, where a ligand-size independent, statistics-based scoring function is developed to evaluate the similarity of ligand molecules relative to random ligand pairs. Large-scale benchmark tests are performed on prioritizing chemical ligands of 102 protein targets involving 1 415 871 candidate compounds from the DUD-E (Database of Useful Decoys: Enhanced) database, where LS-align achieves an average enrichment factor (EF) of 22.0 at the 1% cutoff and the AUC score of 0.75, which are significantly higher than other state-of-the-art methods. Detailed data analyses show that the advanced performance is mainly attributed to the design of the target function that combines structural and chemical information to enhance the sensitivity of recognizing subtle difference of ligand molecules and the introduces of structural flexibility that help capture the conformational changes induced by the ligand-receptor binding interactions. These data demonstrate a new avenue to improve the virtual screening efficiency through the development of sensitive ligand structural alignments.

PMID- 29462238 TI - SecretSanta: flexible pipelines for functional secretome prediction. AB - Motivation: The secretome denotes the collection of secreted proteins exported outside of the cell. The functional roles of secreted proteins include the maintenance and remodelling of the extracellular matrix as well as signalling between host and non-host cells. These features make secretomes rich reservoirs of biomarkers for disease classification and host-pathogen interaction studies. Common biomarkers are extracellular proteins secreted via classical pathways that can be predicted from sequence by annotating the presence or absence of N terminal signal peptides. Several heterogeneous command line tools and web interfaces exist to identify individual motifs, signal sequences and domains that are either characteristic or strictly excluded from secreted proteins. However, a single flexible secretome-prediction workflow that combines all analytic steps is still missing. Results: To bridge this gap the SecretSanta package implements wrapper and parser functions around established command line tools for the integrative prediction of extracellular proteins that are secreted via classical pathways. The modularity of SecretSanta enables users to create tailored pipelines and apply them across the whole tree of life to facilitate comparison of secretomes across multiple species or under various conditions. Availability and implementation: SecretSanta is implemented in the R programming language and is released under GPL-3 license. All functions have been optimized and parallelized to allow large-scale processing of sequences.

PMID- 29462241 TI - flowLearn: fast and precise identification and quality checking of cell populations in flow cytometry. AB - Motivation: Identification of cell populations in flow cytometry is a critical part of the analysis and lays the groundwork for many applications and research discovery. The current paradigm of manual analysis is time consuming and subjective. A common goal of users is to replace manual analysis with automated methods that replicate their results. Supervised tools provide the best performance in such a use case, however they require fine parameterization to obtain the best results. Hence, there is a strong need for methods that are fast to setup, accurate and interpretable. Results: flowLearn is a semi-supervised approach for the quality-checked identification of cell populations. Using a very small number of manually gated samples, through density alignments it is able to predict gates on other samples with high accuracy and speed. On two state-of-the art datasets, our tool achieves median(F1)-measures exceeding 0.99 for 31%, and 0.90 for 80% of all analyzed populations. Furthermore, users can directly interpret and adjust automated gates on new sample files to iteratively improve the initial training.

PMID- 29462242 TI - Gonadotropins and their receptors: coevolution, genetic variants, receptor imaging, and functional antagonists. AB - Gonadotropins belong to the family of dimeric glycoprotein hormones and regulate gonadal physiology mediated by G protein-coupled, seven-transmembrane receptors. These glycoprotein hormones are widely used in the clinic to promote ovarian follicle development and for treating some cases of male infertility. We traced the coevolution of dimeric gonadotropin hormones and their receptors, together with thyrotropin and its receptor. We updated recent findings on human genetic variants of these genes and their association with dizygotic twining, polycystic ovarian syndrome, primary ovarian insufficiency, male-limited precocious puberty, and infertility. In addition to the known physiological roles of gonadotropin receptor signaling in gonadal tissues, we also discussed emerging understanding of extragonadal functions of gonadotropins in bones and adipose tissues, together with recent advances in in vivo imaging of gonadotropin receptors in live animals. Recent development of gonadotropin receptor agonists and antagonists were summarized with an emphasis on the development of functional antagonists for FSH receptors to alleviate osteoporosis and obesity associated with menopause. PMID- 29462243 TI - Combining co-evolution and secondary structure prediction to improve fragment library generation. AB - Motivation: Recent advances in co-evolution techniques have made possible the accurate prediction of protein structures in the absence of a template. Here, we provide a general approach that further utilizes co-evolution constraints to generate better fragment libraries for fragment-based protein structure prediction. Results: We have compared five different fragment library generation programmes on three different datasets encompassing over 400 unique protein folds. We show that considering the secondary structure of the fragments when assembling these libraries provides a critical way to assess their usefulness to structure prediction. We then use co-evolution constraints to improve the fragment libraries by enriching them with fragments that satisfy constraints and discarding those that do not. These improved libraries have better precision and lead to consistently better modelling results.

PMID- 29462244 TI - Scots pine aminopropyltransferases shed new light on evolution of the polyamine biosynthesis pathway in seed plants. AB - Background and Aims: Polyamines are small metabolites present in all living cells and play fundamental roles in numerous physiological events in plants. The aminopropyltransferases (APTs), spermidine synthase (SPDS), spermine synthase (SPMS) and thermospermine synthase (ACL5), are essential enzymes in the polyamine biosynthesis pathway. In angiosperms, SPMS has evolved from SPDS via gene duplication, whereas in gymnosperms APTs are mostly unexplored and no SPMS gene has been reported. The present study aimed to investigate the functional properties of the SPDS and ACL5 proteins of Scots pine (Pinus sylvestris L.) in order to elucidate the role and evolution of APTs in higher plants. Methods: Germinating Scots pine seeds and seedlings were analysed for polyamines by high performance liquid chromatography (HPLC) and the expression of PsSPDS and PsACL5 genes by in situ hybridization. Recombinant proteins of PsSPDS and PsACL5 were produced and investigated for functional properties. Also gene structures, promoter regions and phylogenetic relationships of PsSPDS and PsACL5 genes were analysed. Key Results: Scots pine tissues were found to contain spermidine, spermine and thermospermine. PsSPDS enzyme catalysed synthesis of both spermidine and spermine. PsACL5 was found to produce thermospermine, and PsACL5 gene expression was localized in the developing procambium in embryos and tracheary elements in seedlings. Conclusions: Contrary to previous views, our results demonstrate that SPMS activity is not a novel feature developed solely in the angiosperm lineage of seed plants but also exists as a secondary property in the Scots pine SPDS enzyme. The discovery of bifunctional SPDS from an evolutionarily old conifer reveals the missing link in the evolution of the polyamine biosynthesis pathway. The finding emphasizes the importance of pre-existing secondary functions in the evolution of new enzyme activities via gene duplication. Our results also associate PsACL5 with the development of vascular structures in Scots pine. PMID- 29462246 TI - Carbohydrate Deficient Transferrin in Patients with Cirrhosis: A Tale of Bridges. PMID- 29462247 TI - A new approach for interpreting Random Forest models and its application to the biology of ageing. AB - Motivation: This work uses the Random Forest (RF) classification algorithm to predict if a gene is over-expressed, under-expressed or has no change in expression with age in the brain. RFs have high predictive power, and RF models can be interpreted using a feature (variable) importance measure. However, current feature importance measures evaluate a feature as a whole (all feature values). We show that, for a popular type of biological data (Gene Ontology based), usually only one value of a feature is particularly important for classification and the interpretation of the RF model. Hence, we propose a new algorithm for identifying the most important and most informative feature values in an RF model. Results: The new feature importance measure identified highly relevant Gene Ontology terms for the aforementioned gene classification task, producing a feature ranking that is much more informative to biologists than an alternative, state-of-the-art feature importance measure.

PMID- 29462248 TI - Quality-of-life analysis of the MITO-8, MaNGO, BGOG-Ov1, AGO-Ovar2.16, ENGOT-Ov1, GCIG study comparing platinum-based versus non-platinum-based chemotherapy in patients with partially platinum-sensitive recurrent ovarian cancer. AB - Background: MITO-8 showed that prolonging platinum-free interval by introducing non-platinum-based chemotherapy (NPBC) does not improve prognosis of patients with partially platinum-sensitive recurrent ovarian cancer. Quality of life (QoL) was a secondary outcome. Patients and methods: Ovarian cancer patients recurring or progressing 6-12 months after previous platinum-based chemotherapy (PBC) were randomized to receive PBC or NPBC as first treatment. QoL was assessed at baseline, third and sixth cycles, with the EORTC C-30 and OV-28 questionnaires. Mean changes and best response were analysed. Progression-free survival, response rate, and toxicity are also reported for proper interpretation of data. All analyses were based on intention-to-treat. Results: Out of the 215 patients, 151 (70.2%) completed baseline questionnaire, balanced between the arms; thereafter, missing rate was higher in the NPBC arm. At mean change analysis, C30 scores were prevalently worse in the NPBC than PBC arm, statistical significance being attained for emotional functioning, global health status/QoL, fatigue, and dyspnoea (effect sizes ranging from 0.30 to 0.51). Conversely, as for OV28 scale, the other chemotherapy side-effects item was significantly worse with PBC at three and six cycles, with a larger effect size (0.70 and 0.54, respectively). At best response analysis, improvement of emotional functioning and pain and worsening of peripheral neuropathy and other chemotherapy side-effects were significantly more frequent in the PBC arm. Progression-free survival (median 9 versus 5 months, P = 0.001) and objective response rate (51.6% versus 19.4%, P = 0.0001) were significantly better with PBC. Allergy, blood cell count, alopecia, nausea, musculoskeletal, and neurological side-effects were more frequent and severe with PBC; hand-foot skin reaction, rash/desquamation, mucositis, and vascular events were more frequent with NPBC. Conclusion: MITO-8 QoL analysis shows that deterioration of some functioning and symptom scales is lower with PBC, with improvement of emotional functioning and pain, despite worsening of toxicity-related items. ClinicalTrials.gov: NCT00657878. PMID- 29462249 TI - Effects of cold treatments on fitness and mode of reproduction in the diploid and polyploid alpine plant Ranunculus kuepferi (Ranunculaceae). AB - Background and Aims: Alpine plants grow in harsh environments and are thought to face occasional frost during the sensitive reproductive phase. Apomixis (asexual reproduction via seed) can be advantageous when sexual reproduction is disturbed by cold stress. Apomictic polyploids tend to grow in colder climates than their sexual diploid relatives. Whether cold temperatures actually induce apomixis was unknown to date. Methods: We tested experimentally in climate cabinets for effects of low temperatures and repeated frost on phenology, fitness and mode of reproduction in diploid and tetraploid cytotypes of the alpine species Ranunculus kuepferi. The reproduction mode was determined via flow cytometric seed screening (FCSS). Key Results: Diploids produced the first flowers earlier than the tetraploids in all treatments. Cold treatments significantly reduced the fitness of both cytotypes regarding seed set, and increased the frequency of apomictic seed formation in diploids, but not in tetraploids. Over consecutive years, the degree of facultative apomixis showed individual phenotypic plasticity. Conclusions: Cold stress is correlated to expression of apomixis in warm-adapted, diploid R. kuepferi, while temperature-tolerant tetraploids just maintain facultative apomixis as a possible adaptation to colder climates. However, expression of apomixis may not depend on polyploidy, but rather on failure of the sexual pathway. PMID- 29462250 TI - The lncLocator: a subcellular localization predictor for long non-coding RNAs based on a stacked ensemble classifier. AB - Motivation: The long non-coding RNA (lncRNA) studies have been hot topics in the field of RNA biology. Recent studies have shown that their subcellular localizations carry important information for understanding their complex biological functions. Considering the costly and time-consuming experiments for identifying subcellular localization of lncRNAs, computational methods are urgently desired. However, to the best of our knowledge, there are no computational tools for predicting the lncRNA subcellular locations to date. Results: In this study, we report an ensemble classifier-based predictor, lncLocator, for predicting the lncRNA subcellular localizations. To fully exploit lncRNA sequence information, we adopt both k-mer features and high-level abstraction features generated by unsupervised deep models, and construct four classifiers by feeding these two types of features to support vector machine (SVM) and random forest (RF), respectively. Then we use a stacked ensemble strategy to combine the four classifiers and get the final prediction results. The current lncLocator can predict five subcellular localizations of lncRNAs, including cytoplasm, nucleus, cytosol, ribosome and exosome, and yield an overall accuracy of 0.59 on the constructed benchmark dataset. Availability and implementation: The lncLocator is available at www.csbio.sjtu.edu.cn/bioinf/lncLocator. Supplementary information: Supplementary data are available at Bioinformatics online. PMID- 29462251 TI - Histoplasma Urinary Antigen Testing Obviates the Need for Coincident Serum Antigen Testing. AB - Objectives: Serum and urine antigen (SAg, UAg) detection are common tests for Histoplasma capsulatum. UAg detection is more widely used and reportedly has a higher sensitivity. We investigated whether SAg detection contributes meaningfully to the initial evaluation of patients with suspected histoplasmosis. Methods: We reviewed 20,285 UAg and 1,426 SAg tests ordered from 1997 to 2016 and analyzed paired UAg and SAg tests completed on the same patient within 1 week. We determined the positivity rate for each test. Results: Of 601 paired specimens, 542 were concurrent negatives and 48 were concurrent positives (98% agreement). Medical records were available for eight of 11 pairs with discrepant results. UAg was falsely positive in six instances, truly positive once, and falsely negative once. Conclusions: These findings support using a single antigen detection test, rather than both UAg and SAg, as an initial screen for suspected histoplasmosis. This aligns with the current practice of most physicians. PMID- 29462252 TI - Toward optimizing outcomes in Her2-positive gastric cancer: timing and genomic context matter. PMID- 29462253 TI - Overview of current systemic management of EGFR-mutant NSCLC. AB - Front-line epidermal growth factor receptor tyrosine kinase inhibitor (EGFR TKI) therapy is the standard of care for lung cancer patients with sensitising EGFR mutations (exon 19 deletion or L858R mutation). Several phase III studies have demonstrated the superiority of gefitinib, erlotinib (first generation of TKIs) or afatinib (second generation) to chemotherapy in progression-free survival and response rates. Drug-related toxicities, such as diarrhoea, acneiform skin rash, mucositis, and paronychia, are frequently encountered in patients who receive EGFR TKIs. Other rare side-effects, such as hepatic impairment and interstitial lung disease, should be identified early and managed carefully. Patients with uncommon EGFR mutations, such as G719X, S768I, and L861Q, may require special selection of EGFR TKIs. The combination of erlotinib plus bevacizumab has been accepted in certain parts of the world as an alternative front-line treatment. This review article summarizes the studies leading to the establishment of EGFR TKIs in EGFR-mutant lung cancer patients. The side-effect profiles of the current EGFR TKIs in these large trials are listed, and the management of uncommon EGFR mutations is discussed. Finally, the potential role of combination front-line treatment is discussed. PMID- 29462254 TI - Mechanisms of acquired resistance to first- and second-generation EGFR tyrosine kinase inhibitors. AB - Patients with non-small-cell lung cancer (NSCLC) whose tumours harbour activating mutations within the epidermal growth factor receptor (EGFR) frequently derive significant clinical and radiographic benefits from treatment with EGFR tyrosine kinase inhibitors (TKIs). As such, prospective identification of EGFR mutations is now the standard of care worldwide. However, acquired therapeutic resistance to these agents invariably develops. Over the past 10 years, great strides have been made in defining the molecular mechanisms of EGFR TKI resistance in an effort to design rational strategies to overcome this acquired drug resistance. Approximately 60% of patients with acquired resistance to the EGFR TKIs (erlotinib, gefitinib, and afatinib) develop a new mutation within the drug target. This mutation-T790M-has been shown to alter drug binding and enzymatic activity of the mutant EGF receptor. Less common mechanisms of acquired resistance include MET amplification, ERBB2 amplification, transformation to small-cell lung cancer, and others. Here, we present a condensed overview of the literature on EGFR-mutant NSCLC, paying particular attention to mechanisms of drug resistance, recent clinical trial results, and novel strategies for identifying and confronting drug resistance, while also striving to identify gaps in current knowledge. These advances are rapidly altering the treatment landscape for EGFR-mutant NSCLC, expanding the armamentarium of available therapies to maximize patient benefit. PMID- 29462255 TI - Osimertinib and other third-generation EGFR TKI in EGFR-mutant NSCLC patients. AB - Osimertinib was the first third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) to receive FDA and EMA approval for metastatic EGFR-mutant non-small-cell lung cancer (NSCLC) patients that have acquired the EGFR T790M resistance mutation. Clinical trials have demonstrated the efficacy of osimertinib in this patient population and clinical trials of other third-generation EGFR TKI are currently under way. Additional challenges in this patient population, such as the upfront efficacy of osimertinib, validation of T790M in liquid biopsies as a dynamic predictive marker of efficacy, along with combination with immune checkpoint inhibitors are being explored, representing an extraordinary time of development for EGFR-mutant NSCLC. PMID- 29462256 TI - Molecular mechanisms of acquired resistance to third-generation EGFR-TKIs in EGFR T790M-mutant lung cancer. AB - Lung cancer represents the leading cause of cancer-related deaths worldwide. Despite great advances in its management with the recent emergence of molecular targeted therapies for non-small-cell lung cancer (NSCLC), relapse of the metastatic disease always occurs within approximately one year. Epidermal growth factor receptor (EGFR) mutant tumours are the prime example of oncogene addiction and clonal evolution in oncology, regarding the emergence of resistance to first- and second-generation EGFR inhibitors. Multiple studies have revealed that the EGFR-T790M gatekeeper mutation is the main cause of tumour escape. Recently, irreversible pyrimidine-based EGFR inhibitors especially designed for this particular setting have shown robust clinical activity. However, similar to first and second-generation inhibitors, the development of a diversified set of resistance mechanisms in response to these new compounds is an emerging issue. To date, clinical management of this growing number of patients has not been clearly established, even if anecdotal responses to subsequent molecularly guided therapies have been observed. By exhaustively reviewing and classifying all the preclinical and clinical data published on resistance to third-generation EGFR inhibitors in NSCLC, this work reveals the heterogeneity of the mechanisms that a tumour can develop to evade therapeutic pressure. Strategies currently being tested in clinical trials are discussed in light of these findings. PMID- 29462257 TI - Are liquid biopsies a surrogate for tissue EGFR testing? AB - Molecular profiling has changed the treatment landscape in advanced non-small cell lung cancer. Accurately identifying the tumours that harbour sensitizing EGFR mutations, the most common targetable molecular alteration, as well as those with acquired resistance mutations (e.g. T790M) on treatment is a high clinical priority. The current clinical gold standard is genotyping of tumour specimens. However, the practical utility of this approach is limited by the lack of available tissue and the potential complications associated with biopsies. With the advent of newer sequencing assays, it has become feasible to assess tumour genomics via a blood sample, termed a 'liquid biopsy'. In this review, we summarize the available techniques for liquid biopsies and their applicability for detecting sensitizing and resistance EGFR mutations and how these results may be used for making treatment decisions.

Among the 33 members of TGFbeta superfamily ligands, many act on multiple types of cells within the heart, including cardiomyocytes, cardiac fibroblasts/myofibroblasts, coronary endothelial cells, smooth muscle cells, and immune cells (e.g. monocytes/macrophages and neutrophils). In this review, we highlight recent discoveries on TGFbetas, BMPs, and GDFs in different cardiac residential cellular components, in association with functional impacts in heart development, injury repair, and dysfunction. Specifically, we will review the roles of TGFbetas, BMPs, and GDFs in cardiac hypertrophy, fibrosis, contractility, metabolism, angiogenesis, and regeneration. PMID- 29462262 TI - 50 years of spermatogenesis: Sertoli cells and their interactions with germ cells. AB - The complex morphology of the Sertoli cells and their interactions with germ cells has been a focus of investigators since they were first described by Enrico Sertoli. In the past 50 years, information on Sertoli cells has transcended morphology alone to become increasingly more focused on molecular questions. The goal of investigators has been to understand the role of the Sertoli cells in spermatogenesis and to apply that information to problems relating to male fertility. Sertoli cells are unique in that they are a nondividing cell population that is active for the reproductive lifetime of the animal and cyclically change morphology and gene expression. The numerous and distinctive junctional complexes and membrane specializations made by Sertoli cells provide a scaffold and environment for germ cell development. The increased focus of investigators on the molecular components and putative functions of testicular cells has resulted primarily from procedures that isolate specific cell types from the testicular milieu. Products of Sertoli cells that influence germ cell development and vice versa have been characterized from cultured cells and from the application of transgenic technologies. Germ cell transplantation has shown that the Sertoli cells respond to cues from germ cells with regard to developmental timing and has furthered a focus on spermatogenic stem cells and the stem cell niche. Very basic and universal features of spermatogenesis such as the cycle of the seminiferous epithelium and the spermatogenic wave are initiated by Sertoli cells and maintained by Sertoli-germ cell cooperation. PMID- 29462259 TI - The oocyte-to-embryo transition in mouse: past, present, and future. AB - The oocyte-to-embryo transition (OET) arguably initiates with formation of a primordial follicle and culminates with reprogramming of gene expression during the course of zygotic genome activation. This transition results in converting a highly differentiated cell, i.e. oocyte, to undifferentiated cells, i.e. initial blastomeres of a preimplantation embryo. A plethora of changes occur during the OET and include, but are not limited to, changes in transcription, chromatin structure, and protein synthesis; accumulation of macromolecules and organelles that will comprise the oocyte's maternal contribution to the early embryo; sequential acquisition of meiotic and developmental competence to name but a few. This review will focus on transcriptional and post-transcriptional changes that occur during OET in mouse because such changes are likely the major driving force for OET. We often take a historical and personal perspective, and highlight how advances in experimental methods often catalyzed conceptual advances in understanding the molecular bases for OET. We also point out questions that remain open and therefore represent topics of interest for future investigation. PMID- 29462263 TI - Regular Yogurt Intake and Risk of Cardiovascular Disease Among Hypertensive Adults. AB - BACKGROUND: High blood pressure (HBP) is a major cardiovascular disease (CVD) risk factor. Clinical trials including Dietary Approaches to Stop Hypertension (DASH) have demonstrated beneficial effects of dairy consumption on risks of HBP and CVD. Yogurt, a fermented dairy product, may independently be related to CVD risk. OBJECTIVE: To evaluate the association between yogurt consumption and CVD risk among hypertensive individuals in 2 large cohorts and to determine whether the association differs among those whose eating pattern more closely resembles the DASH diet. METHODS: Overall, 55,898 female Nurses' Health Study (NHS) and 18,232 male Health Professionals Follow-Up Study (HPFS) participants with prevalent HBP were included. Cumulative average estimates of yogurt intake from validated food frequency questionnaires were related to verified self-reported CVD outcomes using Cox proportional hazards models. Hazard ratios and 95% confidence intervals (CI) were adjusted for CVD risk factors, medications, and diet covariates. RESULTS: Yogurt intake was inversely associated with CVD risk (myocardial infarction and stroke) among hypertensive participants (P <0.01 in both cohorts). Among participants consuming >=2 servings/week of yogurt, NHS women had a 17% (95% CI: 0.74-0.92) lower risk while HPFS men experienced a 21% (95% CI: 0.66-0.96) lower CVD risk compared to those who consumed <1 serving/month. Regular yogurt consumers with higher DASH diet scores had 16% (95% CI: 0.73-0.96) and 30% (95% CI: 0.57-0.85) CVD risk reductions in the 2 cohorts, respectively. CONCLUSION: Hypertensive men and women who consumed >=2 servings/week of yogurt, especially in the context of a healthy diet, were at lower risk for developing CVD. PMID- 29462264 TI - The Effect of Ambient Humidity on the Metabolic Rate and Respiratory Patterns of the Hissing Cockroach, Gromphadorhina portentosa (Blattodea: Blaberidae). AB - We examined the effects of humidity on the metabolic rates and respiratory patterns of Gromphadorhina portentosa (Schaum) (Blattodea: Blaberidae) to determine whether insects transition from continuous, cyclical, and discontinuous (DGC) respiration in response to water conservation. Eight male G. portentosa were placed under five different humidity treatments (0, 23, 40, 60, 80% RH). Using flow through respirometry we: (i) determined the effect of humidity on metabolic rate; (ii) observed if changes in metabolic rate were correlated with changes in closed/flutter (CF) or the open (O) phase of DGC; and (iii) determined whether increased spiracular closure was correlated with an increase in water retention. Although G. portentosa had similar rates of CO2 release when placed under 0, 40, 60, and 80% RH, cockroaches placed at 23% RH had a significantly higher metabolic rate. There was no effect of humidity on the duration of the CF phase of the DGC. However, the O phase of DGC was significantly longer when G. portentosa was placed at humidity levels above 23% RH. Interestingly, we saw that the average rate of mass lost to the environment did not change when cockroaches were placed at humidity levels ranging from 0 to 80% RH. This suggests that modulation of the spiracles allows G. portentosa to regulate the amount of water lost to the environment.

PMID- 29462266 TI - Effects of Rifampin and Doxycycline Treatments in Patients With Uncomplicated Scrub Typhus: An Open-Label, Randomized, Controlled Trial. AB - Background: Doxycycline is currently the most frequently used treatment in patients with scrub typhus. However, doxycycline-resistant strains have been found, necessitating the development of a new treatment. Rifampin is known to be effective even for such strains. Our aim in this study was to compare the effects of rifampin and doxycycline treatment in patients with scrub typhus in areas in which resistance to doxycycline has not been reported. Methods: Patients admitted to Chosun University Hospital and regional network hospitals between 2007 and 2009 with a body temperature >=37.5 degrees C and suspected to have scrub typhus were randomly assigned to 1 of 2 treatment groups: a group administered doxycycline 100 mg twice daily for 5 days and a group administered rifampin 600 mg once daily for 5 days. For treatment outcomes, fever, headache, muscle ache, and rash clearance times were compared between the groups. Results: The rifampin and doxycycline groups showed equivalence in all treatment outcomes evaluated. The proportions of patients with fever clearance within 48 hours were similar between groups. Furthermore, there was no significant difference in the occurrence of side effects following drug administration between groups. Conclusions: On the basis of the finding that equivalent treatment effects and safety were found in patient groups that received 600 mg of rifampin and 200 mg of doxycycline, respectively, for 5 days to treat scrub typhus, rifampin may be considered an alternative treatment to doxycycline.

The aim of this study was to investigate whether these drawbacks can be overcome by in situ tissue regeneration using a newly developed synthetic hybrid fabric (SHF). METHODS: The SHF is an expandable, warp-knitted fabric composed of a combination of biodegradable [poly-l-lactic acid (PLLA)] and non-biodegradable (polyethylene terephthalate) yarns. The fabric is coated with cross-linked gelatin. Mechanical properties of the SHF were compared with those of 2 commercial products: expanded polytetrafluoroethylene sheet and glutaraldehyde-treated bovine pericardium. An oval-shaped defect created in the canine descending aorta or inferior vena cava was filled with the SHF patch. After 2 weeks and 1, 3, 6 and 12 (or 24 in the inferior vena cava) months, the patch was removed for histological examination and evaluation of the remaining PLLA. RESULTS: The SHF exhibited satisfactory tensile and suture retention strength for surgical implantation similar to or better than the 2 commercial products. Tissue regeneration was induced with multilayered smooth muscle cells and collagen fibres on both sides of the patch, along with a mature endothelial layer and tissue connections containing vasa vasorum across the patch in the aorta and inferior vena cava. Inflammatory reactions were minimal, and no calcium deposition occurred. The molecular weight of PLLA was reduced to half at 12 months after implantation. CONCLUSIONS: The SHF may solve the drawbacks of the existing products. Further studies of the expandability of the SHF patch after degradation of PLLA are warranted.

AB - Background: This study examined whether smoking cessation in middle age and old age is associated with following a successful trajectory of functional limitations over time in Dutch older adults. Methods: We used 16-year longitudinal data from 645 participants of the Longitudinal Aging Study Amsterdam. Three types of trajectories regarding functional limitations over time were defined: successful (high initial level of functioning and limited decline), late decline (high initial level of functioning and late onset of decline), and early decline (lower initial level of functioning and early onset of decline). Smoking cessation status was self-reported and categorized into: early quitters (stopped in middle age [35-40 years]), late quitters (already smoked in middle age and stopped in old age [>=55 years]), and continued smokers (smoked in middle age and still smoking in old age). Multinomial Logistic Regression Analyses were used to assess the association between smoking cessation and trajectory membership. Results: The sample (55-85 years at baseline) consisted of 20.3% early quitters, 22.9% late quitters, and 56.8% continued smokers. After adjustment for confounders, the model showed that late quitters were less likely to follow an early decline trajectory instead of a successful trajectory compared to continued smokers (odds ratio [OR] = 0.48, 95% confidence interval [CI] = 0.24 0.97). After adjustment for clinically relevant level of depressive symptoms, this association remained substantial but was no longer statistically significant (OR = 0.50, 95% CI = 0.24-1.02). Conclusions: Although not statistically significant in the full model, the observed associations suggest that smoking cessation in old age may have an important impact on daily functioning in old age.

PMID- 29462272 TI - Reasons for conversion and adverse intraoperative events in Endoscopic Port AccessTM atrioventricular valve surgery and minimally invasive aortic valve surgery. AB - OBJECTIVES: This study reports the factors that contribute to sternotomy conversions (SCs) and adverse intraoperative events in minimally invasive aortic valve surgery (MI-AVS) and minimally invasive Endoscopic Port AccessTM atrioventricular valve surgery (MI-PAS). METHODS: In total, 3780 consecutive patients with either aortic valve disease or atrioventricular valve disease underwent minimally invasive valve surgery (MIVS) at our institution between 1 February 1997 and 31 March 2016. MI-AVS was performed in 908 patients (mean age 69.2 +/- 11.3 years, 45.2% women, 6.2% redo cardiac surgery) and MI-PAS in 2872 patients (mean age 64.1 +/- 13.3 years, 46.7% women, 12.2% redo cardiac surgery). RESULTS: A cumulative total of 4415 MIVS procedures (MI-AVS = 908, MI-PAS = 3507) included 1537 valve replacements (MI-AVS = 896, MI-PAS = 641) and 2878 isolated or combined valve repairs (MI-AVS = 12, MI-PAS = 2866). SC was required in 3.0% (n = 114 of 3780) of MIVS patients, which occurred in 3.1% (n = 28 of 908) of MI AVS patients and 3.0% (n = 86 of 2872) of MI-PAS patients, respectively. Reasons for SC in MI-AVS included inadequate visualization (n = 4, 0.4%) and arterial cannulation difficulty (n = 7, 0.8%). For MI-PAS, SC was required in 54 (2.5%) isolated mitral valve procedures (n = 2183). Factors that contributed to SC in MI PAS included lung adhesions (n = 35, 1.2%), inadequate visualization (n = 2, 0.1%), ventricular bleeding (n = 3, 0.1%) and atrioventricular dehiscence (n = 5, 0.2%). Neurological deficit occurred in 1 (0.1%) and 3 (3.5%) MI-AVS and MI-PAS conversions, respectively. No operative or 30-day mortalities were observed in MI AVS conversions (n = 28). The 30-day mortality associated with SC in MI-PAS (n = 86) was 10.5% (n = 9). CONCLUSIONS: MIVS is increasingly being recognized as the 'gold-standard' for surgical valve interventions in the context of rapidly expanding catheter-based technology and increasing patient expectations. Surgeons need to be aware of factors that contribute to SC and adverse intraoperative outcomes to ensure that patients enjoy the maximum potential benefit of MIVS and to apply effective risk reduction strategies that encourage safer and sustainable MIVS programmes.

Although the current synthetic inhibitors used in targeted therapies have improved patient prognosis, toxicity and development of resistance to these agents remain a challenge. Plant-derived natural products and their derivatives have historically been used to treat various diseases, including cancer. Several leading chemotherapeutic agents are directly or indirectly based on botanical natural products. Beyond these important drugs, however, a number of crude herbal or botanical preparations have also shown promising utility for cancer and other disorders. One such natural resource is derived from certain plants of the family Annonaceae, which are widely distributed in tropical and subtropical regions. Among the best known of these is Annona muricata, also known as soursop, graviola or guanabana. Extracts from the fruit, bark, seeds, roots and leaves of graviola, along with several other Annonaceous species, have been extensively investigated for anticancer, anti-inflammatory and antioxidant properties. Phytochemical studies have identified the acetogenins, a class of bioactive polyketide-derived constituents, from the extracts of Annonaceous species, and dozens of these compounds are present in different parts of graviola. This review summarizes current literature on the therapeutic potential and molecular mechanism of these constituents from A.muricata against cancer and many non-malignant diseases. Based on available data, there is good evidence that these long-used plants could have both chemopreventive and therapeutic potential. Appropriate attention to safety studies will be important to assess their effectiveness on various diseases caused or promoted by inflammation. PMID- 29462275 TI - Excitation of Cortical nNOS/NK1R Neurons by Hypocretin 1 is Independent of Sleep Homeostasis. AB - We have proposed that cortical nNOS/NK1R interneurons have a role in sleep homeostasis. The hypocretins (orexins) are wake-promoting neuropeptides and hypocretin/orexin (Hcrt) neurons project to the cortex. Hcrt peptides affect deep layer cortical neurons, and Hcrt receptor 1 (Hcrtr1; Ox1r) mRNA is expressed in cortical nNOS/NK1R cells. Therefore, we investigated whether Hcrt neuron stimulation affects cingulate cortex nNOS/NK1R neurons. Bath application of HCRT1/orexin-A evoked an inward current and membrane depolarization in most nNOS/NK1R cells which persisted in tetrodotoxin; optogenetic stimulation of Hcrt terminals expressing channelrhodopsin-2 confirmed these results, and pharmacological studies determined that HCRTR1 mediated these responses. Single cell RT-PCR found Hcrtr1 mRNA in 31% of nNOS/NK1R cells without any Hcrtr2 mRNA expression; immunohistochemical studies of Hcrtr1-EGFP mice confirmed that a minority of nNOS/NK1R cells express HCRTR1. When Hcrt neurons degenerated in orexin-tTA;TetO DTA mice, the increased EEG delta power during NREM sleep produced in response to 4 h sleep deprivation and c-FOS expression in cortical nNOS/NK1R cells during recovery sleep were indistinguishable from that of controls. We conclude that Hcrt excitatory input to these deep layer cells is mediated through HCRTR1 but is unlikely to be involved in the putative role of cortical nNOS/NK1R neurons in sleep homeostasis. PMID- 29462276 TI - Influence of Rearing Substrates and Nontarget Hosts on the Bionomics of the Tachinid Parasitoid Nemorilla maculosa (Diptera: Tachinidae). AB - The tachinid Nemorilla maculosa Meigen (Diptera: Tachinidae) was introduced from Taiwan to Benin for evaluating its potential as a biocontrol candidate against the cowpea pest Maruca vitrata (Fabricius) (Lepidoptera: Crambidae). To optimize its rearing, we assessed the influence of M. vitrata larval age and rearing substrate-cowpea germinating grains and peabush leaves-on its life table parameters, while its host specificity was investigated with regard to nontarget effects. Parasitism rates were higher when older larvae (10- and 14-d old) were offered to females of N. maculosa compared to the younger (2-, 4-, and 6-d old) host larvae. Regardless of the rearing substrate, development time was longer for females than males, and females lived longer than males irrespective of the age of the host. Sex ratio did not vary significantly with host ages or rearing substrate. The average number of eggs laid by a female reared from M. vitrata larvae feeding on cowpea germinating grains or peabush leaves was 94.2 +/- 4.38 and 71.9 +/- 1.70 eggs, respectively. The host suitability of N. maculosa was assessed by testing four nontarget Lepidoptera species: Spodoptera littoralis Boisduval (Lepidoptera: Noctuidae), Sesamia calamistis Hampson (Lepidoptera: Noctuidae), Corcyra cephalonica (Stainton) (Lepidoptera: Pyralidae), and Eldana saccharina Walker (Lepidoptera: Pyralidae). Larvae of S. littoralis and C. cephalonica were successfully parasitized while N. maculosa did not develop in the larvae of E. saccharina and S. calamistis although they were parasitized. Despite the potential of N. maculosa as a biological control agent against the pod borer M. vitrata, more detailed nontarget studies, extending to other native Crambidae species, are needed before making decisions on field releases. PMID- 29462277 TI - The value of oligoclonal bands in the multiple sclerosis diagnostic criteria. AB - The presence of oligoclonal bands in clinically isolated syndromes is an independent risk factor for developing multiple sclerosis and has been largely excluded from the more recent multiple sclerosis diagnostic criteria. Therefore, our objective was to explore the value of oligoclonal bands in the context of the 2010 McDonald criteria, especially in patients fulfilling exclusively dissemination in space at baseline. For this purpose, we selected 566 patients from a clinically isolated syndrome inception cohort who had IgG oligoclonal bands determination and sufficient data on baseline brain MRI to assess dissemination in space and time. We excluded the cases already fulfilling both dissemination in space and time and divided the remaining 398 into 'no dissemination in space and time' (n = 218), 'dissemination in space' (n = 164) and 'dissemination in time' (n = 16). We assessed Cox proportional hazards regression models with 2010 McDonald as the outcome, using 'no dissemination in space and time' with 0 lesions and negative oligoclonal bands as the reference for different subgroups according to oligoclonal bands status (positive/negative). To assess the diagnostic properties, we selected cases with a follow-up >=3 years or fulfilling 2010 McDonald within 3 years of the clinically isolated syndrome (n = 314), and compared the performance of all 'dissemination in space' cases (n = 137) versus patients with 'dissemination in space' and positive oligoclonal bands (n = 101). The remaining patients classified as fulfilling 'dissemination in time' or 'no dissemination in space and time' were taken into account to calculate the diagnostic properties. The respective adjusted hazard ratios (95% confidence interval) were 1.5 (0.4-5.7) for 'no dissemination in space and time' with 0 lesions and positive oligoclonal bands, 3.1 (1.4-7.2) for 'no dissemination in space and time' with >=1 lesions and negative oligoclonal bands, 7.4 (3.5-15.7) for 'no dissemination in space and time' with >=1 lesions and positive oligoclonal bands, 10.4 (4.8-22.6) for 'dissemination in space' with negative oligoclonal bands, 15.3 (7.5-31.3) for 'dissemination in space' with positive oligoclonal bands, and 9.1 (3.5-23.4) for 'dissemination in time' (not subdivided due to the sample size). The specificity for all cases with 'dissemination in space' was 80.6 and increased to 88.1 after selecting those with positive oligoclonal bands. According to these results, we propose radiological dissemination in space at any time plus positive oligoclonal bands as an additional criterion for diagnosing multiple sclerosis. PMID- 29462278 TI - Neonatal Ethanol Disturbs the Normal Maturation of Parvalbumin Interneurons Surrounded by Subsets of Perineuronal Nets in the Cerebral Cortex: Partial Reversal by Lithium. AB - Reduction in parvalbumin-positive (PV+) interneurons is observed in adult mice exposed to ethanol at postnatal day 7 (P7), a late gestation fetal alcohol spectrum disorder model. To evaluate whether PV+ cells are lost, or PV expression is reduced, we quantified PV+ and associated perineuronal net (PNN)+ cell densities in barrel cortex. While PNN+ cell density was not reduced by P7 ethanol, PV cell density decreased by 25% at P90 with no decrease at P14. PNN+ cells in controls were virtually all PV+, whereas more than 20% lacked PV in ethanol-treated adult animals. P7 ethanol caused immediate apoptosis in 10% of GFP+ cells in G42 mice, which express GFP in a subset of PV+ cells, and GFP+ cell density decreased by 60% at P90 without reduction at P14. The ethanol effect on PV+ cell density was attenuated by lithium treatment at P7 or at P14-28. Thus, reduced PV+ cell density may be caused by disrupted cell maturation, in addition to acute apoptosis. This effect may be regionally specific: in the dentate gyrus, P7 ethanol reduced PV+ cell density by 70% at P14 and both PV+ and PNN+ cell densities by 50% at P90, and delayed lithium did not alleviate ethanol's effect. PMID- 29462279 TI - Mechanisms for the establishment and maintenance of pregnancy: synergies from scientific collaborations. AB - Research on the functions of interferon tau (IFNT) led to the theory of pregnancy recognition signaling in ruminant species. But IFNT does much more as it induces expression of interferon regulatory factor 2 (IRF2) in uterine luminal (LE), superficial glandular (sGE), but not glandular (GE) epithelia. First, IRF2 silences transcription of the estrogen receptor alpha gene and, indirectly, transcription of the oxytocin receptor gene to abrogate development of the luteolytic mechanism to prevent regression of the corpus luteum and its production of progesterone for establishing and maintaining pregnancy. Second, IRF2 silences expression of classical interferon-stimulated genes in uterine LE and sGE; however, uterine LE and sGE respond to progesterone (P4) and IFNT to increase expression of genes for transport of nutrients into the uterine lumen such as amino acids and glucose. Other genes expressed by uterine LE and sGE encode for adhesion molecules such as galectin 15, cathepsins, and cystatins for tissue remodeling, and hypoxia-inducible factor relevant to angiogenesis and survival of blastocysts in a hypoxic environment. IFNT is also key to a servomechanism that allows uterine epithelia, particularly GE, to proliferate and to express genes in response to placental lactogen and placental growth hormone in sheep. The roles of secreted phosphoprotein 1 are also discussed regarding its role in implantation in sheep and pigs, as well as its stimulation of expression of mechanistic target of rapamycin mRNA and protein which is central to proliferation, migration, and gene expression in the trophectoderm cells. PMID- 29462282 TI - Pathophysiological understanding of HFpEF: microRNAs as part of the puzzle. AB - Half of all heart failure patients have preserved ejection fraction (HFpEF). Comorbidities associated with and contributing to HFpEF include obesity, diabetes and hypertension. Still, the underlying pathophysiological mechanisms of HFpEF are unknown. A preliminary consensus proposes that the multi-morbidity triggers a state of systemic, chronic low-grade inflammation, and microvascular dysfunction, causing reduced nitric oxide bioavailability to adjacent cardiomyocytes. As a result, the cardiomyocyte remodels its contractile elements and fails to relax properly, causing diastolic dysfunction, and eventually HFpEF. HFpEF is a complex syndrome for which currently no efficient therapies exist. This is notably due to the current one-size-fits-all therapy approach that ignores individual patient differences. MicroRNAs have been studied in relation to pathophysiological mechanisms and comorbidities underlying and contributing to HFpEF. As regulators of gene expression, microRNAs may contribute to the pathophysiology of HFpEF. In addition, secreted circulating microRNAs are potential biomarkers and as such, they could help stratify the HFpEF population and open new ways for individualized therapies. In this review, we provide an overview of the ever expanding world of non-coding RNAs and their contribution to the molecular mechanisms underlying HFpEF. We propose prospects for microRNAs in stratifying the HFpEF population. MicroRNAs add a new level of complexity to the regulatory network controlling cardiac function and hence the understanding of gene regulation becomes a fundamental piece in solving the HFpEF puzzle.

PMID- 29462281 TI - Linking hospital patient records for suspected or established acute coronary syndrome in a complex secondary care system: a proof-of-concept e-registry in National Health Service Scotland. AB - Aims: To implement secondary care electronic record linkage for patients hospitalized with suspected or known acute coronary syndrome (ACS) in a complex regional health care system and evaluate this e-Registry in terms of patterns of service delivery and 1-year outcomes. Methods and results: Existing electronic hospital records were linked to create episodes of care using (i) a patient administration system, (ii) invasive cardiovascular procedure referrals, and (iii) a catheter laboratory record. Data were extracted for admissions (1 October 2013-30 September 2014) with International Classification of Disease (ICD)-10 diagnosis of angina (I200-I209), myocardial infarction (I210-I229), other ischaemic heart disease (I240-I249) or heart failure (I50), linked to other sources to develop a secondary care ACS e-registry and analysed within a Safe Haven. Episodes of care were categorized into care pathways and evaluated in terms of patient characteristics, as well as service delivery metrics and outcomes including mortality. In all, 2327 patients had 2472 episodes of care. Diagnoses were hierarchically classified as ST-elevation myocardial infarction (STEMI) (586, 25.2%), non-ST-elevation myocardial infarction (NSTEMI) (1068, 45.9%), unspecified myocardial infarction (146, 6.3%), unstable angina (527, 22.6%) for the first hospitalization for each patient within the study period. Six care pathways were mapped. Percutaneous coronary intervention rate for STEMI was 80.2% and for NSTEMI 33.1%. Unadjusted all-cause mortality was 9.0% and 3.0% for STEMI and NSTEMI at 30 days, rising to 11.9% and 11.6% at 1 year. Analyses were validated by independent source data verification. Conclusion: The e registry has enabled analysis of ACS hospitalizations in a complex health care system with implications for quality improvement and research. PMID- 29462284 TI - A matter of thrombosis: different thrombus-like formations in balloon-expandable transcatheter aortic valve prostheses. AB - OBJECTIVES: Transcatheter aortic valve implantation is a treatment strategy for degenerated aortic valve prostheses, but there is some concern regarding valve thrombosis. The optimal anticoagulation strategy for implantation of a transcatheter aortic valve prosthesis remains unclear. METHODS: Aortic root models with the Sapien-XT and S3 prostheses (sizes 23 and 26) fixed in a Perimount Magna Ease bioprosthesis (sizes 23 and 25) were constructed. The haemodynamics of the left ventricle were imitated in a proved in vitro model. Milk was used for coagulation after 90s. Different areas of the leaflets (W: wall coagulation, C: commissure coagulation left/right and S: sinus coagulation) were examined and the number of thrombus-like formations was counted. RESULTS: A total of 54% of the thrombus-like formations were found in the sinus, 28% at the wall area, 13% at the right commissure and 10% at the left commissure. Significant differences were detected at the wall area. S3 prostheses had significantly more thrombus-like formations than the XT prostheses. Additionally, in the S3 prostheses, the thrombus-like formation resembled a film whereas in the XT prostheses, the thrombus-like formation was like the crumbs of a cake. We noted exactly the same pattern in explanted prostheses from patients. CONCLUSIONS: The Sapien prostheses tend to form thromboses due to their flow properties. More than half of the thrombus-like formations were seen in the sinus. The S3 prostheses had significantly more thrombus-like formations than the XT prostheses in the wall area. There are different patterns of thrombus-like formations in XT and S3 prostheses used for transcatheter aortic valve implantation both in vivo and in vitro. PMID- 29462285 TI - Association of 10-year C-reactive protein trajectories with markers of healthy aging: findings from the English Longitudinal Study of Ageing. AB - Background: Elevated systematic inflammation is a hallmark of aging, but the association of long-term inflammation trajectories with subsequent aging phenotypes has been little examined. We assessed inflammatory marker C-reactive protein (CRP) repeatedly over time and examined whether long-term changes predicted aging outcomes. Methods: A total of 2,437 men and women aged 47-87 years at baseline (1998-2001) who were participants in the English Longitudinal Study of Ageing had CRP measured on two or three occasions between 1998 and 2009. Inflammation trajectories were computed using latent-class growth mixture modelling and were related to aging outcomes measured in 2012/2013: physical functioning, cardiometabolic, respiratory, mental health, and a composite "healthy aging" outcome. Results: Four CRP trajectories were identified: 'stable low' (71% of the sample) with baseline mean 1.33mg/L remaining <3mg/L; 'medium-to high' (14%) with baseline 2.7mg/L rising to 5.3mg/L; 'high-to-medium' (10%) with baseline 6.6mg/L decreasing to 2.4mg/L; 'stable-high' (5%) with levels from 5.7 to 7.5mg/L. Relative to the stable-low trajectory, individuals in the medium-to high had a higher risk of limitations in basic activities of daily living (ADL, Odds Ratio; 95% Confidence Interval: 2.09; 1.51,2.88), instrumental ADL (1.62; 1.15,2.30), impaired balance (1.59; 1.20,2.11) and walking speed (1.61; 1.15,2.24), arthritis (1.55; 1.16,2.06), hypertension (1.57; 1.21,2.04), obesity (1.95; 1.36,2.80), poor respiratory function (1.84; 1.36,2.50), and depression (1.55; 1.13,2.12). A lower odds of healthy aging was observed in people in the medium-to-high (0.57; 0.40,0.79) and stable-high (0.50; 0.27,0.91) trajectories. Conclusions: Older people who displayed an elevation in CRP levels over a decade experienced an increased risk of adverse aging outcomes. PMID- 29462286 TI - The c-index is not proper for the evaluation of $t$-year predicted risks. AB - We show that the widely used concordance index for time to event outcome is not proper when interest is in predicting a $t$-year risk of an event, for example 10 year mortality. In the situation with a fixed prediction horizon, the concordance index can be higher for a misspecified model than for a correctly specified model. Impropriety happens because the concordance index assesses the order of the event times and not the order of the event status at the prediction horizon. The time-dependent area under the receiver operating characteristic curve does not have this problem and is proper in this context. PMID- 29462287 TI - Cytoskeletal Associated Filamin A and RhoA Affect Neural Progenitor Specification During Mitosis. AB - Neural progenitor proliferation and cell fate decision from self-renewal to differentiation are crucial factors in determining brain size and morphology. The cytoskeletal dependent regulation of these processes is not entirely known. The actin-binding filamin A (FlnA) was shown to regulate proliferation of progenitors by directing changes in cell cycles proteins such as Cdk1 during G2/M phase. Here we report that functional loss of FlnA not only affects the rate of proliferation by altering cell cycle length but also causes a defect in early differentiation through changes in cell fate specification. FlnA interacts with Rho GTPase RhoA, and FlnA loss impairs RhoA activation. Disruption of either of these cytoskeletal associated proteins delays neurogenesis and promotes neural progenitors to remain in proliferative states. Aurora kinase B (Aurkb) has been implicated in cytokinesis, and peaks in expression during the G2/M phase. Inhibition of FlnA or RhoA impairs Aurkb degradation and alters its localization during mitosis. Overexpression of Aurkb replicates the same delay in neurogenesis seen with loss of FlnA or RhoA. Our findings suggest that shared cytoskeletal processes can direct neural progenitor proliferation by regulating the expression and localization of proteins that are implicated in the cell cycle progression and cell fate specification.

AB - A panel of experts was convened by the Infectious Diseases Society of America (IDSA) and Society for Healthcare Epidemiology of America (SHEA) to update the 2010 clinical practice guideline on Clostridium difficile infection (CDI) in adults. The update, which has incorporated recommendations for children (following the adult recommendations for epidemiology, diagnosis, and treatment), includes significant changes in the management of this infection and reflects the evolving controversy over best methods for diagnosis. Clostridium difficile remains the most important cause of healthcare-associated diarrhea and has become the most commonly identified cause of healthcare-associated infection in adults in the United States. Moreover, C. difficile has established itself as an important community pathogen. Although the prevalence of the epidemic and virulent ribotype 027 strain has declined markedly along with overall CDI rates in parts of Europe, it remains one of the most commonly identified strains in the United States where it causes a sizable minority of CDIs, especially healthcare associated CDIs. This guideline updates recommendations regarding epidemiology, diagnosis, treatment, infection prevention, and environmental management.

PMID- 29462291 TI - Risk Factors for Recurrent Helicobacter cinaedi Bacteremia and the Efficacy of Selective Digestive Decontamination With Kanamycin to Prevent Recurrence. AB - Background: Previous studies suggest that Helicobacter cinaedi can cause recurrent bacteremia. In this study, we elucidated the risk factors for recurrent H. cinaedi bacteremia and explored the efficacy of selective digestive decontamination (SDD) as a preventive measure. Methods: We retrospectively reviewed the medical records of patients with H. cinaedi bacteremia between March 2009 and December 2016 at 2 Japanese hospitals. Results: We identified 168 patients with H. cinaedi bacteremia. Bacteremia recurred in 34 patients. The 100 day cumulative incidence rate of recurrent bacteremia was 18.7%. In univariate analysis of factors associated with recurrent bacteremia, anticancer chemotherapy (hazard ratio [HR], 3.75; 95% confidence interval [CI], 1.86-7.58; P < .001), systemic steroids (HR, 3.79; 95% CI, 1.70-8.45; P = .0011), and hematological malignancy (HR, 3.18; 95% CI, 1.64-6.19; P < .001) were detected. Multivariate analysis indicated that anticancer chemotherapy (HR, 2.47; 95% CI, 1.19-5.12; P = .015) and systemic steroids (HR, 2.40; 95% CI, 1.03-5.61; P = .044) were the independent risk factors. Of the 168 patients, 47 received SDD. According to Gray's test, SDD might have reduced the rate of recurrence but this was not statistically significant (HR, 0.46; 95% CI, 0.18-1.18; P = .11). However, in a proportional hazard modeling analysis, SDD reduced the rate of recurrence (HR, 0.36; 95% CI, 0.13-1.00; P = .050). Conclusions: The 100-day cumulative incidence of recurrent H. cinaedi bacteremia was 18.7%. Anticancer chemotherapy and systemic steroids were independent risk factors for recurrent bacteremia. SDD is a potential strategy for reducing the recurrence. PMID- 29462292 TI - State and non-state mental health service collaboration in a South African district: a mixed methods study. AB - The Life Esidimeni tragedy in South Africa showed that, despite significant global gains in recognizing the salience of integrated public mental health care during the past decade, crucial gaps remain. State and non-state mental health service collaboration is a recognized strategy to increase access to care and optimal use of community resources, but little evidence exist about how it unfolds in low- to middle-income countries. South Africa's Mental Health Policy Framework and Strategic Plan 2013-20 (MHPF) underlines the importance of collaborative public mental health care, though it is unclear how and to what extent this happens. The aim of the study was to explore the extent and nature of state and non-state mental health service collaboration in the Mangaung Metropolitan District, Free State, South Africa. The research involved an equal status, sequential mixed methods design, comprised of social network analysis (SNA) and semi-structured interviews. SNA-structured interviews were conducted with collaborating state and non-state mental health service providers. Semi structured interviews were conducted with collaborating partners and key stake holders. Descriptive network analyses of the SNA data were performed with Gephi, and thematic analysis of the semi-structured interview data were performed in NVivo. SNA results suggested a fragmented, hospital centric network, with low average density and clustering, and high authority and influence of a specialist psychiatric hospital. Several different types of collaborative interactions emerged, of which housing and treatment adherence a key point of collaboration. Proportional interactions between state and non-state services were low. Qualitative data expanded on these findings, highlighting the range of available mental health services, and pointed to power dynamics as an important consideration in the mental health service network. The fostering of a well integrated system of care as proposed in the MHPF requires inter-institutional arrangements that include both clinical and social facets of care, and improvements in local governance.

AB - Gap junction beta-1 (GJB1) gene mutations affecting the gap junction protein connexin32 (Cx32) cause the X-linked Charcot-Marie-Tooth disease (CMT1X), a common inherited neuropathy. Targeted expression of virally delivered Cx32 in Schwann cells following intrathecal injection of lentiviral vectors in the Cx32 knockout (KO) mouse model of the disease has led to morphological and functional improvement. To examine whether this approach could be effective in CMT1X patients expressing different Cx32 mutants, we treated transgenic Cx32 KO mice expressing the T55I, R75W or N175D CMT1X mutations. All three mutants were localized in the perinuclear compartment of myelinating Schwann cells consistent with retention in the ER (T55I) or Golgi (R75W, N175D) and loss of physiological expression in the non-compact myelin. Following intrathecal delivery of the GJB1 gene we detected the virally delivered wild-type (WT) Cx32 in non-compact myelin of T55I KO mice, but only rarely in N175D KO or R75W KO mice, suggesting dominant negative effects of the R75W and N175D mutants but not of the T55I mutant on co expressed WT Cx32. GJB1 treated T55I KO mice showed improved motor performance, lower ratios of abnormally myelinated fibers and reduction of inflammatory cells in spinal roots and peripheral nerves compared with mock-treated littermates. Either partial (N175D KO) or no (R75W KO) improvement was observed in the other two mutant lines. Thus, certain CMT1X mutants may interfere with gene addition therapy for CMT1X. Whereas gene addition can be used for non-interfering CMT1X mutations, further studies will be needed to develop treatments for patients harboring interfering mutations. PMID- 29462295 TI - An expanded enzyme toolbox for production of cis, cis-muconic acid and other shikimate pathway derivatives in Saccharomyces cerevisiae. AB - A wide range of commercially relevant aromatic chemicals can be synthesized via the shikimic acid pathway. Thus, this pathway has been the target of diverse metabolic engineering strategies. In the present work, an optimized yeast strain for production of the shikimic acid pathway intermediate 3-dehydroshikimate (3 DHS) was generated, which is a precursor for the production of the valuable compounds cis, cis-muconic acid (CCM) and gallic acid (GA). Production of CCM requires the overexpression of the heterologous enzymes 3-DHS dehydratase AroZ, protocatechuic acid (PCA) decarboxylase AroY and catechol dioxygenase CatA. The activity of AroY limits the yield of the pathway. This repertoire of enzymes was expanded by a novel fungal decarboxylase. Introducing this enzyme into the pathway in the optimized strain, a titer of 1244 mg L-1 CCM could be achieved, yielding 31 mg g-1 glucose. This represents the highest yield of this compound reported in Saccharomyces cerevisiae to date. To demonstrate the applicability of the optimized strain for production of other compounds from 3-DHS, we overexpressed AroZ together with a mutant of a para-hydroxybenzoic acid hydroxylase with improved substrate specificity for PCA, PobAY385F. Thereby, we could demonstrate the production of GA for the first time in S. cerevisiae. PMID- 29462296 TI - Public health monitoring of hypertension, diabetes and elevated cholesterol: comparison of different data sources. AB - Background: Three data sources are generally used in monitoring health on the population level. Health interview surveys (HISs) are based on participants' self report. Health examination surveys (HESs) yield more objective data, and also persons who are unaware of their elevated risks can be detected. Medical records (MRs) and other administrative registers also provide objective data, but their availability, coverage and quality vary between countries. We summarized studies comparing self-reported data with (i) measured data from HESs or (ii) MRs. We aimed to describe differences in feasibility and comparability of different data sources for monitoring (i) elevated blood pressure or hypertension (ii) elevated blood glucose or diabetes and (iii) elevated total cholesterol. Methods: We conducted a literature search to identify studies, which validated self-reported measures against objective measures. We found 30 studies published since the year 2000 fulfilling our inclusion criteria (targeted to adults and comparing prevalence among the same persons). Results: Hypertension and elevated total cholesterol were prone to be under-estimated in HISs. The under-estimate was more pronounced, when the HIS data were compared with HES data, and lower when compared with MRs. For diabetes, the HISs and the objective methods resulted in fairly similar prevalence rates. Conclusion: The three data sources measure different manifestations of the risk factors and cannot be expected to yield similar prevalence rates. Using HIS data only may lead to under-estimation of elevated risk factor levels or disease prevalence. Whenever possible, information from the three data sources should be evaluated and combined.

PMID- 29462299 TI - Purification and molecular characterization of a Metschnikowia saccharicola killer toxin lethal to a crab pathogenic yeast. AB - The marine yeast strain Metschnikowia saccharicola DD21-2, isolated from sediments in the Yalu River, produces a killer toxin with a lethal effect on Metschnikowia bicuspidate strain WCY, a pathogenic yeast strain that infects crabs. In this study, the killer toxin was purified and characterized. After sequential purification, the purity of the killer toxin was increased 72.2-fold over the purity of the yeast cell culture supernatant. The molecular weight of the purified killer toxin was 47.0 kDa. The optimal pH and temperature for killing activity were 5.5 degrees C and 16 degrees C, respectively. The killing activity was stable over a pH range of 4.0-6.5 and temperature range of 0 degrees C-40 degrees C. The purified killer toxin was only effective against toxin sensitive integral cells and had no killing effect on the protoplasts of toxin sensitive cells. When exerting the killing effect, the toxin bind to a cell wall receptor of the treated strain, disrupted cell wall integrity and eventually caused death. The amino acid sequence identified by mass spectroscopy indicated that the purified killer toxin might be a protein kinase, but did not show beta 1,3-glucanase activity, consistent with the laminarin hydrolysis results. These findings provide a basis for disease prevention and control in marine aquaculture. PMID- 29462298 TI - Th17 cells differentiated with mycelial membranes of Candida albicans prevent oral candidiasis. AB - Candida albicans is a human commensal that causes opportunistic infections. Th17 cells provide resistance against mucosal infection with C. albicans; however, the T cell antigens remain little known. Our final goal is to find effective T cell antigens of C. albicans that are responsible for immunotherapy against candidiasis. Here, we prepared fractions including cytosol, membrane and cell wall from yeast and mycelial cells. Proteins derived from a membrane fraction of mycelial cells effectively induced differentiation of CD4+ T cells into IL-17A producing Th17 cells. To confirm the immunological response in vivo of proteins from mycelial membrane, we performed adoptive transfer experiments using ex vivo stimulated CD4+ T cells from IL-17A-GFP reporter mice. Mycelial membrane differentiated CD4+ Th17 cells adoptively transferred intravenously prevented oral candidiasis by oral infection of C. albicans, compared with control anti-CD3 stimulated CD4+ T cells. This was confirmed by the clinical score and the number of neutrophils on the infected tissues. These data suggest that effective T cell antigens against candidiasis could be present in the membrane protein fraction of mycelial cells. The design of novel vaccination strategies against candidiasis will be our next step. PMID- 29462300 TI - DNA stable-isotope probing identifies uncultivated members of Pseudonocardia associated with biodegradation of pyrene in agricultural soil. AB - Identifying functional microorganisms involved in the degradation of high molecular-mass polycyclic aromatic hydrocarbons (HMM-PAHs) in agricultural soil environments could assist in developing bioremediation strategies for soil PAH contamination. Active populations of HMM-PAH degraders in agricultural soils are currently poorly understood. In this study, we identified aerobic pyrene degrading bacteria in agricultural and industrial soils by [13C]pyrene incubations followed by DNA stable-isotope probing and high-throughput sequencing. More than 80% of pyrene was degraded during an incubation time of 35 days in both soils, with slower mineralization rates observed in agricultural soil compared with industrial soil. Members of the Pseudonocardia genus, not previously implicated in pyrene degradation, were the dominant pyrene-degrading population in agricultural soil; their relative abundance increased by three orders of magnitude. In industrial soil, Arthrobacter sp. appeared as the major pyrene degraders, while Pseudonocardia was not detectable. Mycobacterium, a group of well-known pyrene degraders, was found to be active in pyrene degradation in both soils. These results highlight the role of uncultivated members of Pseudonocardia in natural PAH biodegradation processes and expand our understanding of the metabolic potential of uncultivated microorganisms for bioremediation applications in agricultural soils. PMID- 29462301 TI - Secreted bacterial RNA: an unexplored avenue. AB - Gradually, it is becoming clear that our well-being depends significantly on the contribution and composition of microorganisms that are associated with us. The majority of human-associated microorganisms are bacteria, which maintain their niche through interactions with the human host and neighboring microorganisms. Secretory products contribute largely to maintaining their position in a complex ecosystem. The role of bacterial-released secreted RNA (seRNA) is mostly unexplored, and the study on seRNA will open a new branch in science. There are observations that have demonstrated the functional potential of seRNA, but more investigations are required to cover the entire path from their origin to function. PMID- 29462302 TI - Isolation of marine xylene-utilizing bacteria and characterization of Halioxenophilus aromaticivorans gen. nov., sp. nov. and its xylene degradation gene cluster. AB - Seven xylene-utilizing bacterial strains were isolated from seawater collected off the coast of Japan. Analysis of 16S rRNA gene sequences indicated that six isolates were most closely related to the marine bacterial genera Alteromonas, Marinobacter or Aestuariibacter. The sequence of the remaining strain, KU68FT, showed low similarity to the 16S rRNA gene sequences of known bacteria with validly published names, the most similar species being Maricurvus nonylphenolicus strain KU41ET (92.6% identity). On the basis of physiological, chemotaxonomic and phylogenetic data, strain KU68FT is suggested to represent a novel species of a new genus in the family Cellvibrionaceae of the order Cellvibrionales within the Gammaproteobacteria, for which the name Halioxenophilus aromaticivorans gen. nov., sp. nov. is proposed. The type strain of Halioxenophilus aromaticivorans is KU68FT (=JCM 19134T = KCTC 32387T). PCR and sequence analysis revealed that strain KU68FT possesses an entire set of genes encoding the enzymes for the upper xylene methyl-monooxygenase pathway, xylCMABN, resembling the gene set of the terrestrial Pseudomonas putida strain mt-2.

AB - People working in Ghana's informal sector have low rates of enrolment in the publicly funded National Health Insurance Scheme. Informal sector workers, including migrant girls and women from northern Ghana working as head porters (kayayei), report challenges obtaining insurance and seeking formal health care. This article analyses how health insurance status affects kayayei migrants' care seeking behaviours. This mixed-methods study involved surveying 625 migrants using respondent-driven sampling and conducting in-depth interviews with a sub sample of 48 migrants. Analyses explore health status and health seeking behaviours for recent illness/injury. Binary logistic regression modelled the effects of selected independent variables on whether or not a recently ill/injured participant (n = 239) sought health care. Although recently ill/injured participants (38.4%) desired health care, less than half (43.5%) sought care. Financial barriers overwhelmingly limit kayayei migrants from seeking health care, preventing them from registering with the National Health Insurance Scheme, renewing their expired health insurance policies, or taking time away from work. Both insured and uninsured migrants did not seek formal health services due to the unpredictable nature of out-of-pocket expenses. Catastrophic and impoverishing medical expenses also drove participants' migration in search of work to repay loans and hospital bills. Health insurance can help minimize these expenditures, but only 17.4% of currently insured participants (58.2%) reported holding a valid health insurance card in Accra. The others lost their cards or forgot them when migrating. Access to formal health care in Accra remains largely inaccessible to kayayei migrants who suffer from greater illness/injury than the general female population in Accra and who are hindered in their ability to receive insurance exemptions. With internal migration on the rise in many settings, health systems must recognize the varied needs of populations in multi-ethnic and multilingual countries to ensure that internal migrants can access affordable, quality health services across domestic borders. PMID- 29462303 TI - SNAIL Mediates TGF-beta1-Induced Downregulation of Pentraxin 3 Expression in Human Granulosa Cells. AB - Transforming growth factor-beta (TGF-beta) 1 plays a critical role in regulating follicular development, and its dysregulation has been shown to be involved in the pathogenesis of ovulation dysfunction. SNAIL is a well-known transcriptional repressor that mediates TGF-beta1-induced cellular functions. Pentraxin 3 (PTX3) is a key enzyme for the assembly and stabilization of the cumulus oophorus extracellular matrix, which is essential for cumulus expansion during the periovulatory stage. The purpose of the present study was to investigate the roles of TGF-beta1 and SNAIL in the regulation of PTX3 expression and to examine the underlying mechanism. An established immortalized human granulosa cell (GC) line (SVOG), a GC tumor cell line (KGN), and primary human granulosa-lutein cells were used as study models. We demonstrated that TGF-beta1 treatment substantially decreased the messenger RNA and protein levels of PTX3. This suppressive effect was abolished by cotreatment with the soluble TGF-beta type II receptor (TbetaRII) or the ALK4/5/7 inhibitor SB431542. Knockdown of ALK5, SMAD2/3, or SMAD4 reversed the effects of TGF-beta1-induced SNAIL upregulation and PTX3 suppression. These results indicate that TGF-beta1 upregulates SNAIL and downregulates PTX3 expression via a TbetaRII-ALK5-mediated SMAD-dependent signaling pathway in human GCs. Additionally, TGF-beta1-induced PTX3 suppression was mediated by upregulation of the SNAIL transcription factor, as knockdown of SNAIL completely reversed the suppression of PTX3 in response to TGF-beta1. These findings could inform the roles of TGF-beta1 and SNAIL in the regulation of follicular function and might provide therapeutic targets for the treatment of ovulation dysfunction. PMID- 29462306 TI - A multicentre stewardship initiative to decrease excessive duration of antibiotic therapy for the treatment of community-acquired pneumonia. AB - Background: The increased emphasis on pneumonia-related performance measures and patient outcomes has led hospitals to implement multifaceted approaches to quickly identify patients with community-acquired pneumonia (CAP), start timely therapy and reduce readmission. However, there has been minimal focus on duration of therapy (DOT) and patients often receive prolonged antibiotic courses. The IDSA and American Thoracic Society (IDSA/ATS) CAP guidelines recommend 5 days of therapy for clinically stable patients that quickly defervesce and stewardship teams are well positioned to influence prescribing practices. Objectives: Determine the impact of a prospective stewardship intervention on total antibiotic DOT and associated clinical outcomes in hospitalized patients with CAP. Methods: This multicentre, quasi-experimental study evaluated three concurrent interventions over a 6 month period to promote appropriate DOT. All centres updated institutional CAP guidelines to promote IDSA/ATS-concordant DOT, provided education and conducted daily audit and feedback with intervention to provide patient-specific DOT recommendations. Results: A total of 600 patients with CAP were included (307 in the historical control group and 293 in the stewardship intervention group). The stewardship intervention increased compliance with DOT recommendations (42% versus 5.6%, P < 0.001) and reduced the median DOT per patient (6 versus 9 days, P < 0.001). Clinical outcomes, including mortality, readmission with pneumonia, presentation to the emergency centre/clinic with pneumonia and incidence of Clostridium difficile infection within 30 days of discharge, were not different between groups. Conclusions: This multicentre evaluation of a stewardship intervention in hospitalized CAP patients reduced the total antibiotic DOT and increased guideline-concordant DOT without adversely affecting patient outcomes. PMID- 29462307 TI - 'Artlift' arts-on-referral intervention in UK primary care: updated findings from an ongoing observational study. AB - Background: Arts for health interventions are an accepted option for medical management of mental wellbeing in health care. Updated findings are presented from a prospective longitudinal follow-up (observational) design study of an arts on referral programme in UK general practice, over a 7-year period (2009-2016). Methods: Primary care process and mental wellbeing outcomes were investigated, including progress through the intervention, changes in mental wellbeing, and factors associated with those outcomes. A total of n =1297 patients were referred to an eight or 10-week intervention over a period from 2009 to 2016. Patient sociodemographic information was recorded at baseline, and patient progress (e.g. attendance) assessed throughout the intervention. Results: Of all referrals, 51.7% completed their course of prescribed art (the intervention). Of those that attended, 74.7% engaged with the intervention as rated by the artists leading the courses. A significant increase in wellbeing was observed from pre- to post intervention (t = -19.29, df =523, P < 0.001, two-tailed) for those that completed and/or engaged. A sub sample (N =103) of these referrals self-reported multi-morbidities. These multiple health care service users were majority completers (79.6%), and were rated as having engaged (81.0%). This group also had a significant increase in well-being, although this was smaller than for the group as a whole (t = -7.38, df =68, P < 0.001). Conclusion: Findings confirm that art interventions can be effective in the promotion of well-being for those that complete, including those referred with multi-morbidity, with significant changes in wellbeing evident across the intervention periods.

PMID- 29462309 TI - Fixation of CO2 and CO on a diverse range of carbohydrates using anaerobic, non photosynthetic mixotrophy. AB - Biological CO2 fixation is an important technology that can assist in combating climate change. Here, we show an approach called anaerobic, non-photosynthetic mixotrophy can result in net CO2 fixation when using a reduced feedstock. This approach uses microbes called acetogens that are capable of concurrent utilization of both organic and inorganic substrates. In this study, we investigated the substrate utilization of 17 different acetogens, both mesophilic and thermophilic, on a variety of different carbohydrates and gases. Compared to most model acetogen strains, several non-model mesophilic strains displayed greater substrate flexibility, including the ability to utilize disaccharides, glycerol and an oligosaccharide, and growth rates. Three of these non-model strains (Blautia producta, Clostridium scatologenes and Thermoanaerobacter kivui) were chosen for further characterization, under a variety of conditions including H2- or syngas-fed sugar fermentations and a CO2-fed glycerol fermentation. In all cases, CO2 was fixed and carbon yields approached 100%. Finally, the model acetogen C. ljungdahlii was engineered to utilize glucose, a non-preferred sugar, while maintaining mixotrophic behavior. This work demonstrates the flexibility and robustness of anaerobic, non-photosynthetic mixotrophy as a technology to help reduce CO2 emissions. PMID- 29462310 TI - Bulk soil and maize rhizosphere resistance genes, mobile genetic elements and microbial communities are differently impacted by organic and inorganic fertilization. AB - Organic soil fertilizers, such as livestock manure and biogas digestate, frequently contain bacteria carrying resistance genes (RGs) to antimicrobial substances and mobile genetic elements (MGEs). The effects of different fertilizers (inorganic, manure, digestate) on RG and MGE abundance and microbial community composition were investigated in a field plot experiment. The relative abundances of RGs [sul1, sul2, tet(A), tet(M), tet(Q), tet(W), qacEDelta1/qacE] and MGEs [intI1, intI2, IncP-1, IncP-1epsilon and LowGC plasmids] in total community (TC)-DNA from organic fertilizers, bulk soil and maize rhizosphere were quantified by qPCR before/after fertilization and prior to maize harvest. Microbial communities were analyzed via Illumina sequencing of 16S rRNA gene fragments amplified from TC-DNA. Compared to inorganic fertilization, manure treatments increased relative abundances of all RGs analyzed, integrons and few genera affiliated to Bacteroidetes and Firmicutes in bulk soil, while digestate increased sul2, tet(W) and intI2. At harvest, treatment effects vanished in bulk soil. However, organic fertilizer effects were still detectable in the rhizosphere for RGs [manure: intI1, sul1; digestate: tet(W)] and Clostridium related sequences (digestates) with increased relative abundance. Our data indicated transient organic fertilizer effects on RGs, MGEs and microbial community composition in bulk soil with long-term history of digestate or manure application. PMID- 29462311 TI - Device orientation of a leadless pacemaker and subcutaneous implantable cardioverter-defibrillator in canine and human subjects and the effect on intrabody communication. AB - Aims: The development of communicating modular cardiac rhythm management systems relies on effective intrabody communication between a subcutaneous implantable cardioverter-defibrillator (S-ICD) and a leadless pacemaker (LP), using conducted communication. Communication success is affected by the LP and S-ICD orientation. This study is designed to evaluate the orientation of the LP and S-ICD in canine subjects and measure success and threshold of intrabody communication. To gain more human insights, we will explore device orientation in LP and S-ICD patients. Methods and results: Canine subjects implanted with a prototype S-ICD and LP (both Boston Scientific, MA, USA) with anterior-posterior fluoroscopy images were included in this analysis. For comparison, a retrospective analysis of human S ICD and LP patients was performed. The angle of the long axis of the LP towards the vertical axis of 0 degrees , and distance between the coil and LP were measured. Twenty-three canine subjects were analysed. Median angle of the LP was 29 degrees and median distance of the S-ICD coil to LP was 0.8 cm. All canine subjects had successful communication. The median communicating threshold was 2.5 V. In the human retrospective analysis, 72 LP patients and 100 S-ICD patients were included. The mean angle of the LP was 56 degrees and the median distance between the S-ICD coil and LP was 4.6 cm. Conclusion: Despite the less favourable LP orientation in canine subjects, all communication attempts were successful. In the human subjects, we observed a greater and in theory more favourable LP angle towards the communication vector. These data suggests suitability of human anatomy for conductive intrabody communication. PMID- 29462313 TI - Overexpression of the periplasmic nitrate reductase supports anaerobic growth by Ensifer meliloti. AB - The alfalfa endosymbiont Ensifer meliloti strain1021 is known to be an incomplete denitrifier due to its inability to grow anoxically using nitrate as respiratory substrate to produce ATP and grow under anoxic conditions. Although this bacterium contains and expresses the complete set of denitrification genes napEFDABC, nirK, norECBQD and nosRZDFYLX encoding the periplasmic nitrate reductase (Nap), Cu-containing nitrite reductase (NirK), c-type nitric oxide (cNor) and nitrous oxide reductase (Nos), respectively, the reasons of its inability to grow under anoxic conditions are still very poorly understood. In the present study, we have constructed an E. meliloti strain overexpressing napEFDABC genes (Nap+) and demonstrated that this strain is able to grow through anaerobic nitrate respiration. Furthermore, Nap+ showed increased NapC levels as well as Nap, Nir and cNor activities and higher capacity to produce NO and N2O compared to wild-type cells. These results suggest that the inability of E. meliloti to grow under anaerobic conditions using nitrate as electron acceptor is attributable to a limitation in the expression of the periplasmic nitrate reductase. PMID- 29462312 TI - MYO9A deficiency in motor neurons is associated with reduced neuromuscular agrin secretion. AB - Congenital myasthenic syndromes (CMS) are a group of rare, inherited disorders characterized by compromised function of the neuromuscular junction, manifesting with fatigable muscle weakness. Mutations in MYO9A were previously identified as causative for CMS but the precise pathomechanism remained to be characterized. On the basis of the role of MYO9A as an actin-based molecular motor and as a negative regulator of RhoA, we hypothesized that loss of MYO9A may affect the neuronal cytoskeleton, leading to impaired intracellular transport. To investigate this, we used MYO9A-depleted NSC-34 cells (mouse motor neuron-derived cells), revealing altered expression of a number of cytoskeletal proteins important for neuron structure and intracellular transport. On the basis of these findings, the effect on protein transport was determined using a vesicular recycling assay which revealed impaired recycling of a neuronal growth factor receptor. In addition, an unbiased approach utilizing proteomic profiling of the secretome revealed a key role for defective intracellular transport affecting proper protein secretion in the pathophysiology of MYO9A-related CMS. This also led to the identification of agrin as being affected by the defective transport. Zebrafish with reduced MYO9A orthologue expression were treated with an artificial agrin compound, ameliorating defects in neurite extension and improving motility. In summary, loss of MYO9A affects the neuronal cytoskeleton and leads to impaired transport of proteins, including agrin, which may provide a new and unexpected treatment option.

PMID- 29462315 TI - Overexpression of Stenotrophomonas maltophilia major facilitator superfamily protein MfsA increases resistance to fluoroquinolone antibiotics. AB - Background: Stenotrophomonas maltophilia is an opportunistic human pathogen causing nosocomial infections worldwide. S. maltophilia infection is of particular concern due to its inherent resistance to currently used antibiotics. Proton motive force-driven transporters of the major facilitator superfamily frequently contribute to the efflux of substances, including antibiotics, across cell membranes. Methods: An mfsA expression plasmid (pMfsA) was constructed and transferred into bacterial strains by electroporation. The antibiotic susceptibility levels of S. maltophilia strains were determined using standard methods. Results and conclusions: S. maltophilia MfsA is an efflux pump associated with paraquat resistance. We show here that plasmid-mediated overexpression of mfsA in WT S. maltophilia K279a increased resistance not only to paraquat but also to second-generation fluoroquinolone antibiotics, i.e. ciprofloxacin, norfloxacin, levofloxacin and ofloxacin. Ciprofloxacin was used as a representative drug. Addition of the proton motive force inhibitor carbonyl cyanide-m-chlorophenylhydrazone increases susceptibility to ciprofloxacin. Taken together these results suggest that MsfA is a novel fluoroquinolone efflux pump of S. maltophilia. Moreover, heterologous expression of mfsA in other Gram negative pathogenic bacteria conferred resistance to paraquat as well as to fluoroquinolones. Thus, if this determinant was horizontally transferred, it could cause the spread of fluoroquinolone resistance among bacterial species.

PMID- 29462317 TI - Evaluation of microribonucleic acids as potential biomarkers in the bicuspid aortic valve-associated aortopathy. AB - OBJECTIVES: We aimed to evaluate the impact of microRNAs to predict the bicuspid aortic valve (BAV)-associated aortopathy. METHODS: Sixty-three BAV patients (mean age 47 +/- 11 years, 92% men) with root dilatation, who underwent aortic valve +/ proximal aortic surgery (mean post-AVR follow-up 10.3 +/- 6.9 years) were included. The BAV aortopathy entities were categorized in the 'less dilated' (aortic root <50 mm) and 'severely dilated' (aortic root >=50 mm) aorta. Several microRNAs were assessed using polymerase chain reaction. End-points were the correlation between microRNAs and severity of aortopathy/prevalence of adverse aortic events. RESULTS: Circulating levels of miR-17 and miR-106a were strongly correlated (r = 0.84, P < 0.001). Our analysis yielded significantly higher values of miR-17 (delta Ct 2.09 +/- 0.64 vs delta Ct 1.68 +/- 0.64, P = 0.02) and miR-106a (delta Ct 5.88 +/- 0.43 vs delta Ct 5.61 +/- 0.60, P = 0.046) in BAV patients with the less dilated versus the severely dilated aorta. miR-17 (delta Ct 1.51 +/- 0.73 vs delta Ct 2.00 +/- 0.61, P = 0.02) and miR-106a (delta Ct 5.39 +/- 0.69 vs delta Ct 5.85 +/- 0.44, P = 0.007) were significantly downregulated in BAV patients who experienced adverse aortic events. CONCLUSIONS: Expression of circulating miR-17 and miR-106a in the BAV root phenotype patients correlates with the severity of aortopathy and the risk of adverse aortic events. MicroRNAs have the potential to serve as biomarkers in the BAV-associated aortopathy. PMID- 29462318 TI - Reply to Nevez et al. PMID- 29462319 TI - Cell-free fetal DNA testing in singleton IVF conceptions. AB - STUDY QUESTION: Are fetal fraction, test failure rate and positive predictive value (PPV) of cell-free fetal DNA (cffDNA) testing different in singleton IVF conceptions compared to spontaneous conceptions? SUMMARY ANSWER: Fetal fraction is significantly lower; test failure rate is higher and PPV of cffDNA testing is lower in singleton pregnancies conceived by IVF than those conceived spontaneously. WHAT IS ALREADY KNOWN: cffDNA testing, which analyses circulating cffDNA in maternal blood, has very high accuracy for detection of trisomy 21 in the general obstetric population. Focused and conclusive evidence regarding the test characteristics of cffDNA testing in IVF conceived pregnancies is lacking. STUDY DESIGN, SIZE, DURATION: This was a retrospective cohort study including spontaneously and IVF conceived singleton pregnancies collected consecutively between April 2013 and November 2016. A total of 4633 spontaneously conceived and 992 IVF pregnancies were included. PARTICIPANTS/MATERIALS, SETTING, METHODS: The study was performed at an obstetric and gynecological ultrasound clinic in Melbourne, Australia. Participants had screening for trisomies 21, 18 and 13, as well as sex chromosome aneuploidies (SCA) performed with cffDNA testing after 10 weeks' gestation. Multivariate regression analysis was used to determine significant predictors of logarithmically transformed fetal fraction and test failure. Comparison of test characteristics between study groups was performed adopting a significance level of 5%. MAIN RESULTS AND THE ROLE OF CHANCE: Median fetal fraction was lower (10.3% [interquartile range (IQR), 7.7-13.5] versus 11.9% [IQR, 9.1-15.0]; P = 0.005), test failure rate was higher (5.2 versus 2.2%; P < 0.001) and positive predictive value (PPV) for trisomies 18, 13 and SCA was poorer in IVF pregnancies compared to those spontaneously conceived. Multivariate linear regression analysis demonstrated that IVF conception, increased BMI, earlier gestational age and South and East Asian ethnicities were independent predictors of lower fetal fraction. Multiple logistic regression analysis found IVF conception and increased BMI to be independently associated with test failure. PPV was high for trisomy 21 in IVF conception (100.0%), but was lower for other trisomies when compared with the non-IVF population. LIMITATIONS REASONS FOR CAUTION: IVF details were unascertainable for 210 cases, as the information was not available through our data collection points. Inability to karyotype some cases at high-risk for SCA, due to patients' choice, and the occurrence of miscarriages and terminations, resulted in the exclusion of high risk cases when calculating PPV.

PMID- 29462320 TI - Air Quality Inside Police Drug Safes and Drug Storage Areas. AB - Storage of drug-based evidence inside sealed safes may allow chemical vapors to accumulate, creating concerns of drug exposure by inhalation, or the possibility of cross-contamination of drug evidence. Air samples were taken from inside eight drug safes and one small storage room at nine city and country police stations, as well as a large centralized drug evidence storage vault, in New South Wales (NSW), Australia. Sorbent tubes containing charcoal were used to determine whether any drug residues could be detected in the air, and to identify the types of chemicals present. Carbon traps were extracted and analyzed by LC-MS-MS for a suite of 22 licit and illicit drug residues and 2 metabolites. Carbon traps and SPME fibers were also analyzed by GC-MS for general volatile organic compound (VOC) residues. No detectable drug residues, either as airborne dust or vapor, were found in the safes, the storage room or the large central repository vault. No drugs were detected in any of the 34 urine samples collected at 8 of the 10 sampling locations, while only one of the five hair samples was positive for cocaine (9 pg/mg) provided by police exhibit officers at 3 of the 10 sampling locations. VOC analysis identified a variety of solvents associated with drug manufacture, plasticisers, personal care products and volatiles associated with plants such as cannabis. The results indicate that strong chemical odours emanating from drug safes are unlikely to be drug residues due to low volatility of drugs, and are more likely VOCs associated with their manufacture or from plant growing operations. Consideration should be given to the quality of air flow in rooms in which safes are housed and the use of air filtering inside safes to reduce the likelihood of VOC accumulation, and therefore the risk of human exposure.

AB - Our laboratory received segments of umbilical cord that originated from identical twins for routine toxicology analysis. The specimens were analyzed multiple times by liquid chromatography tandem mass spectrometry. The umbilical cord from newborn #1 was positive for hydromorphone only (1.06 ng/g), and the umbilical cord from newborn #2 was positive for hydromorphone (0.81 ng/g) and benzoylecgonine (5.41 ng/g). The hydromorphone results are consistent with maternal administration of hydromorphone; however, the cause of the discrepant benzoylecgonine results in the umbilical cords from the identical twins is unknown. PMID- 29462322 TI - Primary resistance to integrase strand transfer inhibitors in patients infected with diverse HIV-1 subtypes in sub-Saharan Africa. AB - Objectives: To investigate the prevalence and patterns of major and accessory resistance mutations associated with integrase strand transfer inhibitors (INSTIs), across diverse HIV-1 subtypes in sub-Saharan Africa. Methods: pol gene sequences were obtained using Illumina next-generation sequencing from 425 INSTI naive HIV-infected adults from Kenya (21.2%), Nigeria (7.3%), South Africa (22.8%), Uganda (25.2%) and Zambia (23.5%). Drug resistance interpretation was based on the IAS 2017 mutation list and accessory mutations from Stanford HIVdb with resistance penalty scores of >=10 to at least 1 INSTI. Resistance was further classified based on sensitivity thresholds of >=20% (Sanger sequencing) and 1%-20% for low-frequency variants (next-generation sequencing). Results: Of 425 genotypes, 48.7% were subtype C, 28.5% A, 10.1% D, 2.8% G and 9.9% were recombinants. Major INSTI resistance mutations were detected only at <20% threshold, at a prevalence of 2.4% (2.5% in subtype A, 2.4% C, 0% D, 8.3% G and 2.4% in recombinants) and included T66A/I (0.7%), E92G (0.5%), Y143C/S (0.7%), S147G (0.2%) and Q148R (0.5%). Accessory mutations occurred at a prevalence of 15.1% at the >=20% threshold (23.1% in subtype A, 8.7% C, 11.6% D, 25% G and 23.8% in recombinants), and included L74I/M (10.4%), Q95K (0.5%), T97A (4%), E157Q (0.7%) and G163R/K (0.7%). Conclusions: Major INSTI resistance mutations were rare and only occurred at low-level resistance detection thresholds. INSTI based regimens are expected to be effective across the different major HIV-1 subtypes in the region. PMID- 29462323 TI - Longitudinal analysis strategies for modelling epigenetic trajectories. AB - Background: DNA methylation levels are known to vary over time, and modelling these trajectories is crucial for our understanding of the biological relevance of these changes over time. However, due to the computational cost of fitting multilevel models across the epigenome, most trajectory modelling efforts to date have focused on a subset of CpG sites identified through epigenome-wide association studies (EWAS) at individual time-points. Methods: We propose using linear regression across the repeated measures, estimating cluster-robust standard errors using a sandwich estimator, as a less computationally intensive strategy than multilevel modelling. We compared these two longitudinal approaches, as well as three approaches based on EWAS (associated at baseline, at any time-point and at all time-points), for identifying epigenetic change over time related to an exposure using simulations and by applying them to blood DNA methylation profiles from the Accessible Resource for Integrated Epigenomics Studies (ARIES). Results: Restricting association testing to EWAS at baseline identified a less complete set of associations than performing EWAS at each time point or applying the longitudinal modelling approaches to the full dataset. Linear regression models with cluster-robust standard errors identified similar sets of associations with almost identical estimates of effect as the multilevel models, while also being 74 times more efficient. Both longitudinal modelling approaches identified comparable sets of CpG sites in ARIES with an association with prenatal exposure to smoking (>70% agreement). Conclusions: Linear regression with cluster-robust standard errors is an appropriate and efficient approach for longitudinal analysis of DNA methylation data. PMID- 29462324 TI - Endometriosis induces gut microbiota alterations in mice. AB - STUDY QUESTION: What happens to the gut microbiota during development of murine endometriosis? SUMMARY ANSWER: Mice with the persistence of endometrial lesions for 42 days develop a distinct composition of gut microbiota. WHAT IS KNOWN ALREADY: Disorders in the immune system play fundamental roles in changing the intestinal microbiota. No study has used high-throughput DNA sequencing to show how endometriosis changes the gut microbiota, although endometriosis is accompanied by abnormal cytokine expression and immune cell dysfunction. STUDY DESIGN, SIZE, DURATION: This study includes a prospective and randomized experiment on an animal endometriosis model induced via the intraperitoneal injection of endometrial tissues. PARTICIPANTS/MATERIALS, SETTING, METHODS: The mice were divided into endometriosis and mock groups and were sacrificed at four different time points for model confirmation and fecal sample collection. To detect gut microbiota, 16S ribosomal-RNA gene sequencing was performed. Alpha diversity was used to analyze the complexity and species diversity of the samples through six indices. Beta diversity analysis was utilized to evaluate the differences in species complexity. Principal coordinate analysis and unweighted pair-group method with arithmetic means clustering were performed to determine the clustering features. The microbial features differentiating the fecal microbiota were characterized by linear discriminant analysis effect size method. MAIN RESULTS AND THE ROLE OF CHANCE: The endometriosis and mock mice shared similar diversity and richness of gut microbiota. However, different compositions of gut microbiota were detected 42 days after the modeling. Among the discriminative concrete features, the Firmicutes/Bacteroidetes ratio was elevated in mice with endometriosis, indicating that endometriosis may induce dysbiosis. Bifidobacterium, which is known as a commonly used probiotic, was also increased in mice with endometriosis. LARGE SCALE DATA: N/A. LIMITATIONS, REASONS FOR CAUTION: More control groups should be further studied to clarify the specificity of the dysbiosis induced by endometriosis. This study was performed only on mice. Thus, additional data acquired from patients with endometriosis are needed in future research. We only detected the changes of gut microbiota at 42 days after the modeling, while the long-term effect of endometriosis on gut microbiota remains poorly understood. Moreover, we only revealed a single effect of endometriosis on gut microbiota. WIDER IMPLICATIONS OF THE FINDINGS: This study provided the first comprehensive data on the association of endometriosis and gut microbiota from high-throughput sequencing technology. The gut microbiota changed with the development of endometriosis in a murine model. The communication between the host and the gut microbiota is bidirectional, and further studies should be performed to clarify their relationship.

AB - During the Salzburg Global Seminar Session 565-'Better Health Care: How do we learn about improvement?', participants discussed the need to unpack the 'black box' of improvement. The 'black box' refers to the fact that when quality improvement interventions are described or evaluated, there is a tendency to assume a simple, linear path between the intervention and the outcomes it yields. It is also assumed that it is enough to evaluate the results without understanding the process of by which the improvement took place. However, quality improvement interventions are complex, nonlinear and evolve in response to local settings. To accurately assess the effectiveness of quality improvement and disseminate the learning, there must be a greater understanding of the complexity of quality improvement work. To remain consistent with the language used in Salzburg, we refer to this as 'unpacking the black box' of improvement. To illustrate the complexity of improvement, this article introduces four quality improvement case studies. In unpacking the black box, we present and demonstrate how Cynefin framework from complexity theory can be used to categorize and evaluate quality improvement interventions. Many quality improvement projects are implemented in complex contexts, necessitating an approach defined as 'probe sense-respond'. In this approach, teams experiment, learn and adapt their changes to their local setting. Quality improvement professionals intuitively use the probe-sense-respond approach in their work but document and evaluate their projects using language for 'simple' or 'complicated' contexts, rather than the 'complex' contexts in which they work. As a result, evaluations tend to ask 'How can we attribute outcomes to the intervention?', rather than 'What were the adaptations that took place?'. By unpacking the black box of improvement, improvers can more accurately document and describe their interventions, allowing evaluators to ask the right questions and more adequately evaluate quality improvement interventions. PMID- 29462326 TI - Secreted frizzled-related protein 2 (SFRP2) expression promotes lesion proliferation via canonical WNT signaling and indicates lesion borders in extraovarian endometriosis. AB - STUDY QUESTION: What is the role of SFRP2 in endometriosis? SUMMARY ANSWER: SFRP2 acts as a canonical WNT/CTNNB1 signaling agonist in endometriosis, regulating endometriosis lesion growth and indicating endometriosis lesion borders together with CTNNB1 (also known as beta catenin). WHAT IS KNOWN ALREADY: Endometriosis is a common, chronic disease that affects women of reproductive age, causing pain and infertility, and has significant economic impact on national health systems. Despite extensive research, the pathogenesis of endometriosis is poorly understood, and targeted medical treatments are lacking. WNT signaling is dysregulated in various human diseases, but its role in extraovarian endometriosis has not been fully elucidated. STUDY DESIGN, SIZE, DURATION: We evaluated the significance of WNT signaling, and especially secreted frizzled related protein 2 (SFRP2), in extraovarian endometriosis, including peritoneal and deep lesions. The study design was based on a cohort of clinical samples collected by laparoscopy or curettage and questionnaire data from healthy controls and endometriosis patients. PARTICIPANTS/MATERIALS, SETTING, METHODS: Global gene expression analysis in human endometrium (n = 104) and endometriosis (n = 177) specimens from 47 healthy controls and 103 endometriosis patients was followed by bioinformatics and supportive qPCR analyses. Immunohistochemistry, Western blotting, primary cell culture and siRNA knockdown approaches were used to validate the findings. MAIN RESULTS AND THE ROLE OF CHANCE: Among the 220 WNT signaling and CTNNB1 target genes analysed, 184 genes showed differential expression in extraovarian endometriosis (P < 0.05) compared with endometrium tissue, including SFRP2 and CTNNB1. Menstrual cycle-dependent regulation of WNT genes observed in the endometrium was lost in endometriosis lesions, as shown by hierarchical clustering. Immunohistochemical analysis indicated that SFRP2 and CTNNB1 are novel endometriosis lesion border markers, complementing immunostaining for the known marker CD10 (also known as MME). SFRP2 and CTNNB1 localized similarly in both the epithelium and stroma of extraovarian endometriosis tissue, and interestingly, both also indicated an additional distant lesion border, suggesting that WNT signaling is altered in the endometriosis stroma beyond the primary border indicated by the known marker CD10. SFRP2 expression was positively associated with pain symptoms experienced by patients (P < 0.05), and functional loss of SFRP2 in extraovarian endometriosis primary cell cultures resulted in decreased cell proliferation (P < 0.05) associated with reduced CTNNB1 protein expression (P = 0.05). LIMITATIONS REASONS FOR CAUTION: SFRP2 and CTNNB1 improved extraovarian endometriosis lesion border detection in a relatively small cohort (n = 20), although larger studies with different endometriosis subtypes in variable cycle phases and under hormonal medication are required. WIDER IMPLICATIONS OF THE FINDINGS: The highly expressed SFRP2 and CTNNB1 improve endometriosis lesion border detection, which can have clinical implications for better visualization of endometriosis lesions over CD10. Furthermore, SFRP2 acts as a canonical WNT/CTNNB1 signaling agonist in endometriosis and positively regulates endometriosis lesion growth, suggesting that the WNT pathway may be an important therapeutic target for endometriosis.

PMID- 29462327 TI - Risk factors for spinal cord ischaemia after thoracic endovascular aortic repair. AB - OBJECTIVES: Spinal cord ischaemia (SCI) is a serious complication of thoracic endovascular aortic repair (TEVAR). The purpose of this study was to assess the incidence, risk factors, clinical manifestations of SCI after TEVAR and which type of patients could benefit from cerebrospinal fluid drainage. METHODS: A retrospective review was conducted for 175 patients who underwent TEVAR from January 2008 to July 2014. All patients were divided into groups with and without SCI, and they were compared to identify significant risk factors for SCI. RESULTS: The incidence of SCI after TEVAR including paraplegia and paraparesis was 6.9%. SCI usually occurred within 24 h, but delayed SCI was observed after 5 days in 1 patient. In all patients with SCI, we tried to increase the blood pressure to improve spinal perfusion. Three patients recovered completely, and the 6 patients with some remaining neurological deficit included 3 with motion against gravity and bladder dysfunction and the 3 remaining patients with only bladder dysfunction. Three patients did not recover. In our study, significant risk factors for SCI were as follows: rupture, shaggy aorta, chronic obstructive pulmonary disease, 1-stage procedure, the coverage of more than 9 segments, the coverage from Th8 to Th12, minimum of postoperative haemoglobin and the number of postoperative patent segmental arteries. CONCLUSIONS: Sufficient perioperative care should be given to high-risk patients who have endografts that cover more than 9 segments and endografts that cover segments from Th8 to Th12. Adequate haemoglobin levels and mean arterial pressure are needed to provide sufficient spinal cord perfusion. PMID- 29462329 TI - Association of job sectors with type 2 diabetes mellitus, hypercholesterolemia and obesity: a cross-sectional study from the Malaysian Cohort (TMC) project. AB - Background: The investigation of risk factors of cardiovascular disease (e.g., major endocrine, nutritional and metabolic diseases) across job sectors is useful for targeted public health intervention. This study examined the occurrence of type 2 diabetes mellitus (T2DM), hypercholesterolemia and obesity in 21 job sectors in the general population. Methods: A baseline cross-sectional analysis of the Malaysian Cohort was conducted, which included 105 391 adults. Multiple logistic regression analyses were conducted for these three diseases across 20 job sectors compared with the unemployed/homemaker sector. Results: The prevalence of T2DM, hypercholesterolemia and obesity was 16.7%, 38.8% and 33.3%, respectively. The Accommodation & Food Service Activities and Transportation & Storage sectors had significantly higher odds for T2DM (adjusted [adj.] prevalence odds ratio [POR] 1.18, p=0.007 and adj. POR 1.15, p=0.008, respectively). No job sector had significantly higher odds for hypercholesterolemia compared with the unemployed/homemaker sector. Only the Accommodation & Food Service Activities sector had significantly higher odds for obesity (adj. POR 1.17, p<=0.001). Conclusions: Many job sectors were significantly associated with lower odds of having these three diseases when compared with the unemployed/homemaker sector. These differing associations between diverse job sectors and these diseases are important for public health intervention initiatives and prioritization. PMID- 29462331 TI - Does a low-income urban population practise healthy dietary habits? AB - Background: The purpose of this study was to identify the unhealthy dietary habits and practices in a low-income community in an urban area and determine the associated factors. Methods: A cross-sectional survey was conducted in a low income housing area in Kuala Lumpur, Malaysia. Data were collected using a questionnaire via face-to-face interviews by trained enumerators in order to obtain details on sociodemographic characteristics and dietary practices. Results: Descriptive statistics showed that 86.7% of the respondents in the low income community consumed fruit and vegetables less than five times per day, 11.7% consumed carbonated and sweetened drinks more than twice per day and about 25% consumed fast food more than four times per month. In total, 65.2% (n=945) did not have healthy dietary practices. Binary logistic regression showed that age, education and ethnicity were significant predictors of unhealthy dietary practices among the low-income community. Those in the 30-59 years age group had higher odds (odds ratio 1.65, p=0.04) of practising an unhealthy diet as compared with those older than 60 years of age. Conclusion: Unhealthy dietary practices were found to be common among the low-income group living in an urban area. Healthy lifestyle intervention should be highlighted so that it can be adopted in the low-income group. PMID- 29462332 TI - Molecular Data Support an Early Shift to an Intermediate-Light Niche in the Evolution of Mammals. AB - The visual ability and associated photic niche of early mammals is debated. The theory that ancestral mammals were nocturnal is supported by diverse adaptations. However, others argue that photopigment repertoires of early mammals are more consistent with a crepuscular niche, and support for this also comes from inferred spectral tuning of middle/long wavelength-sensitive (M/LWS) opsin sequences. Functional studies have suggested that the M/LWS pigment in the ancestor of Mammalia was either red- or green-sensitive; however, these were based on outdated phylogenies with key lineages omitted. By performing the most detailed study to date of middle/long-wave mammalian color vision, we provide the first experimental evidence that the M/LWS pigment of amniotes underwent a 9-nm spectral shift towards shorter wavelengths in the Mammalia ancestor, exceeding predictions from known critical sites. Our results suggest early mammals were yellow-sensitive, possibly representing an adaptive trade-off for both crepuscular (twilight) and nocturnal (moonlight) niches. PMID- 29462330 TI - Cell surface chondroitin sulphate proteoglycan 4 (CSPG4) binds to the basement membrane heparan sulphate proteoglycan, perlecan, and is involved in cell adhesion. AB - Chondroitin sulphate proteoglycan 4 (CSPG4) is a cell surface proteoglycan highly expressed by tumour, perivascular and oligodendrocyte cells and known to be involved cell adhesion and migration. This study showed that CSPG4 was present as a proteoglycan on the cell surface of two melanoma cell lines, MM200 and Me1007, as well as shed into the conditioned medium. CSPG4 from the two melanoma cell lines differed in the amount of chondroitin sulphate (CS) decoration, as well as the way the protein core was fragmented. In contrast, the CSPG4 expressed by a colon carcinoma cell line, WiDr, was predominantly as a protein core on the cell surface lacking glycosaminoglycan (GAG) chains. This study demonstrated that CSPG4 immunopurified from the melanoma cell lines formed a complex with perlecan synthesized by the same cultured cells. Mechanistic studies showed that CSPG4 bound to perlecan via hydrophobic protein-protein interactions involving multiple sites on perlecan including the C-terminal region. Furthermore, this study revealed that CSPG4 interacted with perlecan to support cell adhesion and actin polymerization. Together these data suggest a novel mechanism by which CSPG4 expressing cells might attach to perlecan-rich matrices so as those found in connective tissues and basement membranes. PMID- 29462333 TI - High positive end-expiratory pressure during ex vivo lung perfusion: recruiting rejected donor lungs. AB - We present an innovative method for recruiting clinically rejected donor lungs using positive end-expiratory pressure titration during ex vivo lung perfusion. Currently, ex vivo lung perfusion protocols are using a standard positive end expiratory pressure of 5 cmH2O for all cases. Individualized positive end expiratory pressure titration combined with recruitment manoeuvres has been found to significantly improve pulmonary functions in mechanically ventilated patients. Applying this concept to ex vivo lung perfusion may be helpful in increasing the conversion rate for transplant suitability.

PMID- 29462335 TI - Five-year experience using the Lung Allocation Score: the Munich Lung Transplant Group. AB - OBJECTIVES: The Lung Allocation Score (LAS) was implemented in Germany on 10 December 2011 after demonstrating favourable outcomes in the USA since its introduction in 2005. There are only limited and short-term data on the effect of the LAS on lung transplantation programmes in Germany. The purpose of this study was to analyse our 5-year single-centre experience with the LAS within the influential area of the Eurotransplant Foundation (ET). METHODS: After implementation of the LAS until December 2016, 294 patients underwent a single lung transplantation or a bilateral sequential lung transplantation for end-stage lung disease at our centre. Patients were divided into 4 groups according to their primary diagnosis. The Kaplan-Meier analyses of survival probabilities were performed to compare types of transplant procedures, underlying diagnoses and the LASs at the time of transplantation. Waitlist characteristics, transplant procedures and up to 5-year post-transplant outcomes were analysed. RESULTS: The proportion of lung transplants performed for interstitial lung disease increased over time from 27% in 2012 to 54% in 2016 (P = 0.056). At the same time, the proportion of patients with chronic obstructive pulmonary disease undergoing lung transplantation declined over the 5-year period, i.e. from 29% in 2011 to 19% in 2016 (P = 0.029). Overall waiting times of transplanted patients were approximately 200 days and did not markedly change over time. There was an increasing proportion of chronic obstructive pulmonary disease patients on the waitlist from 41% in 2011 to 51% in 2016 (P = 0.51). Outcomes were independent of the underlying disease entity or the LAS. Bilateral sequential lung transplantation was associated with a better long-term survival probability when compared with a single-lung transplantation (P < 0.001). CONCLUSIONS: Our centre specific 5-year experience confirms previous findings demonstrating that the LAS is a well-established tool for the selection of lung transplant candidates, respecting urgency and prognostic transplant benefit in a disease-specific manner. However, the LAS did not shorten overall waiting times in transplanted patients. Further long-term and multicentre data with respect to differential transplant centre activities have to be gathered for further evaluation. PMID- 29462334 TI - Left frontal hub connectivity delays cognitive impairment in autosomal-dominant and sporadic Alzheimer's disease. AB - Patients with Alzheimer's disease vary in their ability to sustain cognitive abilities in the presence of brain pathology. A major open question is which brain mechanisms may support higher reserve capacity, i.e. relatively high cognitive performance at a given level of Alzheimer's pathology. Higher functional MRI-assessed functional connectivity of a hub in the left frontal cortex is a core candidate brain mechanism underlying reserve as it is associated with education (i.e. a protective factor often associated with higher reserve) and attenuated cognitive impairment in prodromal Alzheimer's disease. However, no study has yet assessed whether such hub connectivity of the left frontal cortex supports reserve throughout the evolution of pathological brain changes in Alzheimer's disease, including the presymptomatic stage when cognitive decline is subtle. To address this research gap, we obtained cross-sectional resting state functional MRI in 74 participants with autosomal dominant Alzheimer's disease, 55 controls from the Dominantly Inherited Alzheimer's Network and 75 amyloid positive elderly participants, as well as 41 amyloid-negative cognitively normal elderly subjects from the German Center of Neurodegenerative Diseases multicentre study on biomarkers in sporadic Alzheimer's disease. For each participant, global left frontal cortex connectivity was computed as the average resting state functional connectivity between the left frontal cortex (seed) and each voxel in the grey matter. As a marker of disease stage, we applied estimated years from symptom onset in autosomal dominantly inherited Alzheimer's disease and cerebrospinal fluid tau levels in sporadic Alzheimer's disease cases. In both autosomal dominant and sporadic Alzheimer's disease patients, higher levels of left frontal cortex connectivity were correlated with greater education. For autosomal dominant Alzheimer's disease, a significant left frontal cortex connectivity * estimated years of onset interaction was found, indicating slower decline of memory and global cognition at higher levels of connectivity. Similarly, in sporadic amyloid-positive elderly subjects, the effect of tau on cognition was attenuated at higher levels of left frontal cortex connectivity. Polynomial regression analysis showed that the trajectory of cognitive decline was shifted towards a later stage of Alzheimer's disease in patients with higher levels of left frontal cortex connectivity. Together, our findings suggest that higher resilience against the development of cognitive impairment throughout the early stages of Alzheimer's disease is at least partially attributable to higher left frontal cortex-hub connectivity. PMID- 29462337 TI - Repeated Systemic Treatment with Rapamycin Affects Behavior and Amygdala Protein Expression in Rats. AB - Background: Clinical data indicate that therapy with small-molecule immunosuppressive drugs is frequently accompanied by an incidence rate of neuropsychiatric symptoms. In the current approach, we investigated in rats whether repeated administration of rapamycin, reflecting clinical conditions of patients undergoing therapy with this mammalian target of rapamycin inhibitor, precipitates changes in neurobehavioral functioning. Methods: Male adult Dark Agouti rats were daily treated with i.p. injections of rapamycin (1, 3 mg/kg) or vehicle for 8 days. On days 6 and 7, respectively, behavioral performance in the Elevated Plus-Maze and the Open-Field Test was evaluated. One day later, amygdala tissue and blood samples were taken to analyze protein expression ex vivo. Results: The results show that animals treated with rapamycin displayed alterations in Elevated Plus-Maze performance with more pronounced effects in the higher dose group. Besides, an increase in glucocorticoid receptor density in the amygdala was seen in both treatment groups even though p-p70 ribosomal S6 kinase alpha, a marker for mammalian target of rapamycin functioning, was not affected. Protein level of the neuronal activity marker c-Fos was again only elevated in the higher dose group. Importantly, effects occurred in the absence of acute peripheral neuroendocrine changes. Conclusions: Our findings indicate that anxiety-related behavior following rapamycin treatment was not directly attributed to mTOR-dependent mechanisms or stress but rather due to hyperexcitability of the amygdala together with glucocorticoid receptor-regulated mechanism(s) in this brain region. Together, the present results support the contention that subchronic treatment with rapamycin may induce neurobehavioral alterations in healthy, naive subjects. We here provide novel insights in central effects of systemic rapamycin in otherwise healthy subjects but also raise the question whether therapy with this drug may have detrimental effects on patients' neuropsychological functioning during immune therapy. PMID- 29462338 TI - Ammonium intensifies CAM photosynthesis and counteracts drought effects by increasing malate transport and antioxidant capacity in Guzmania monostachia. AB - Guzmania monostachia (Bromeliaceae) is a tropical epiphyte capable of up regulating crassulacean acid metabolism (CAM) in its photosynthetic tissues in response to changing nutrient and water availability. Previous studies have shown that under drought there is a gradient of increasing CAM expression from the basal (youngest) to the apical (oldest) portion of the leaves, and additionally that nitrogen deficiency can further increase CAM intensity in the leaf apex of this bromeliad. The present study investigated the inter-relationships between nitrogen source (nitrate and/or ammonium) and water deficit in regulating CAM expression in G. monostachia leaves. The highest CAM activity was observed under ammonium nutrition in combination with water deficit. This was associated with enhanced activity of the key enzyme phosphoenolpyruvate carboxylase, elevated rates of ATP- and PPi-dependent proton transport at the vacuolar membrane in the presence of malate, and increased transcript levels of the vacuolar malate channel-encoding gene, ALMT. Water deficit was consistently associated with higher levels of total soluble sugars, which were maximal under ammonium nutrition, as were the activities of several antioxidant enzymes (superoxide dismutase, catalase, ascorbate peroxidase, and glutathione reductase). Thus, ammonium nutrition, whilst associated with the highest degree of CAM induction in G. monostachia, also mitigates the effects of water deficit by osmotic adjustment and can limit oxidative damage in the leaves of this bromeliad under conditions that may be typical of its epiphytic habitat. PMID- 29462339 TI - A Pilot Study of Neural Correlates of Loss of Control Eating in Children With Overweight/Obesity: Probing Intermittent Access to Food as a Means of Eliciting Disinhibited Eating. AB - Objective: Neural substrates of loss of control (LOC) eating are undercharacterized. We aimed to model intermittent access to food to elicit disinhibited eating in youth undergoing neuroimaging, given evidence that restricted food access may increase subsequent food intake via enhancing reward value of food and diminishing eating-related self-control. Methods: Participants were 18 preadolescents (aged 9-12 years) who were overweight/obese with recent LOC eating (OW-LOC; n = 6); overweight/obese with no history of LOC eating (OW CON; n = 5); or non-overweight with no history of LOC eating (NW-CON; n = 7). Participants underwent functional magnetic resonance imaging during a simulated food restriction paradigm in which they were alternately given restricted or unrestricted access to milkshake solutions. Results: There were no significant main effects of restricted versus unrestricted access to milkshake flavors. Group main effects revealed increased activation for OW-LOC relative to OW-CON in areas related to attentional processes (right middle frontal gyrus), inhibitory control/attentional shifts (right and left cuneus), and emotion regulation (left cingulate gyrus); and for OW-LOC relative to NW-CON in areas related to response inhibition (right inferior frontal gyrus). Significant block type * group interaction effects were found for the right middle frontal gyrus, left cingulate gyrus, and left cuneus, but these appeared to be accounted for primarily by group. Discussion: There were clear group differences in neural activity in brain regions related to self-regulation during a food restriction paradigm. Elevations in these regions among OW-LOC relative to OW-CON and NW-CON, respectively, may suggest that youth with LOC eating expended more cognitive effort to regulate ingestive behavior. PMID- 29462341 TI - Laboratory Evaluation of Commercially Available Platforms to Detect West Nile and Zika Viruses From Honey Cards. AB - Commercially available assays utilizing antigen or nucleic acid detection chemistries provide options for mosquito control districts to screen their mosquito populations for arboviruses and make timely operational decisions regarding vector control. These assays may be utilized even more advantageously when combined with honey-soaked nucleic acid preservation substrate ('honey card') testing by reducing or replacing the time- and labor-intensive efforts of identifying and processing mosquito pools. We tested artificially inoculated honey cards and cards fed upon individually by West Nile virus (WNV) and Zika virus (ZIKV)-infected mosquitoes with three assays to compare detection rates and the limit of detection for each platform with respect to virus detection of a single infected mosquito and quantify the time interval of virus preservation on the cards. Assays evaluated included CDC protocols for real-time reverse transcriptase polymerase chain reaction (RT-PCR) for WNV and ZIKV, Pro-Lab Diagnostics ProAmpRT WNV loop-mediated amplification (LAMP) and ZIKV LAMP assays, and the Rapid Analyte Measurement Platform (RAMP) WNV assay. Real-time RT-PCR was the most sensitive assay and the most robust to viral RNA degradation over time. To maximize the detection of virus, honey cards should be left in the traps <=1 d if using LAMP assays and <=3 d if using real-time RT-PCR to detect viruses from field samples. The WNV RAMP assay, although effective for pool screening, lacks sensitivity required for honey card surveillance. Future studies may determine the minimum number of infectious mosquitoes required to feed on a honey card that would be reliably detected by the LAMP or RAMP assays.

AB - Candida albicans, a human fungal pathogen, is able to tolerate certain levels of environmental stresses. Its cell wall plays an important role in cellular homeostasis, responding to environmental stimuli. SRB1 gene encodes a GDP-mannose pyrophosphorylase that catalyzes the formation of the major cell wall component, mannan. The exact relationship between SRB1 and various stresses is not yet fully understood. In current study, C. albicans SC5314 cells were exposed to oxidative, hyperosmotic, and thermal stresses. The expression of SRB1 and related stress response genes, HOG1, CAP1, MKC1, and HSP90, was systematically evaluated in cells exposed to various levels of stress. In addition, the apoptosis and ultrastructural changes of the cells were examined. We found that the expression of SRB1 and related stress response genes significantly increased under oxidative, hyperosmotic, and thermal stresses, and the increased gene expression was correlated with higher percentages of apoptosis and ultrastructural changes in C. albicans cells. We propose that protein glycosylation is associated with stress response that involves SRB1 in C. albicans. Further in-depth studies of SRB1 function should aid our understanding of C. albicans pathogenesis, and provide important clues about the development of novel antifungal compounds for drug resistant C. albicans.

AB - Background: Understanding disease seasonality is important for improving clinical practice, hospital resource utilization and community-based preventive care. However, no studies have investigated the seasonality of acute kidney injury (AKI). Methods: In the Tokushukai Medical Database, which includes 38 Japanese community hospitals, we identified hospitalized patients with AKI based on the Kidney Disease: Improving Global Outcomes serum creatinine criteria from January 2012 to December 2014. We plotted the number and proportion of patients with AKI among hospitalized patients by month of hospital admission. Subgroup analyses were conducted by the admission diagnosis category, timing of AKI diagnosis and age. We also examined the association between month of hospital admission and AKI, adjusting for patient characteristics and AKI risk factors. Finally, we assessed seasonal variations in disease severity and 30-day mortality of patients with AKI. Results: We identified 81 279 (14.6%) patients with AKI among 555 940 hospitalized patients. The proportion of patients with AKI was highest in January (16.7%) and lowest in June (13.4%). Subgroup analyses suggested that the seasonality of AKI incidence was driven by community-acquired AKI associated with the admission diagnosis of cardiovascular and pulmonary diseases among older patients. The adjusted odds ratio for AKI (January versus June) was 1.24 (95% confidence interval, 1.17-1.31). Patients with AKI showed a larger number of failing organs in winter, and their 30-day mortality was 16.4% in spring, 14.5% in summer, 15.6% in autumn and 18.4% in winter. Conclusion: AKI is more common among hospitalized patients and patients with AKI are more severely ill in winter. PMID- 29462344 TI - Do community pharmacists add value to routine immunization programmes? A review of the evidence from the UK. AB - Background: Community pharmacies are an important setting for the provision of preventative health services in the UK. There has been debate over the value of delivering routine immunizations in a pharmacy setting, though government policy supports this initiative and in 2015 the first nationally commissioned community pharmacy vaccination service was launched for seasonal influenza vaccination. The impact of these vaccination services needs to be evaluated to inform future policy. Methods: We conducted a comprehensive review of peer-reviewed studies and unpublished evaluations of community pharmacy-based vaccination services implemented in the UK between 2000 and 2015. We assessed evidence of their impact on acceptability, uptake, cost-effectiveness and addressing inequalities. Results: We identified 28 evaluations of pharmacy immunization programmes in the UK, only three of which were published in peer-reviewed journals. These showed no evidence of increased vaccination uptake, and weak evidence of widening access to individuals who had not previously been vaccinated. There was good evidence that pharmacies were acceptable and convenient venues for vaccination. Cost effectiveness was not assessed in any of the included studies. Conclusions: Our review challenges an assumption that pharmacy provision of immunizations will simultaneously improve patient choice, increase uptake and widen access. These are important findings for policy makers. PMID- 29462346 TI - A systematic review of economic evaluations of local authority commissioned preventative public health interventions in overweight and obesity, physical inactivity, alcohol and illicit drugs use and smoking cessation in the United Kingdom. AB - Background: Since 2013, local authorities in England have been responsible for commissioning preventative public health interventions. The aim of this systematic review was to support commissioning by collating published data on economic evaluations and modelling of local authority commissioned public health preventative interventions in the UK. Methods: Following the PRISMA protocol, we searched for economic evaluations of preventative intervention studies in four different areas: overweight and obesity, physical inactivity, alcohol and illicit drugs use and smoking cessation. The systematic review identified studies between January 1994 and February 2015, using five databases. We synthesized the studies to identify the key methods and examined results of the economic evaluations. Results: The majority of the evaluations related to cost-effectiveness, rather than cost-benefit analyses or cost-utility analyses. These analyses found preventative interventions to be cost effective, though the context of the interventions differed between the studies. Conclusions: Preventative public health interventions in general are cost-effective. There is a need for further studies to support justification of continued and/or increased funding for public health interventions. There is much variation between the types of economically evaluated preventative interventions in our review. Broader studies incorporating different contexts may help support funding for local authority-sponsored public health initiatives. PMID- 29462345 TI - Dynamics of metabolic responses to periods of combined heat and drought in Arabidopsis thaliana under ambient and elevated atmospheric CO2. AB - As a consequence of global change processes, plants will increasingly be challenged by extreme climatic events, against a background of elevated atmospheric CO2. We analysed responses of Arabidopsis thaliana to periods of a combination of elevated heat and water deficit at ambient and elevated CO2 in order to gain mechanistic insights regarding changes in primary metabolism. Metabolic changes induced by extremes of climate are dynamic and specific to different classes of molecules. Concentrations of soluble sugars and amino acids increased transiently after short (4-d) exposure to heat and drought, and readjusted to control levels under prolonged (8-d) stress. In contrast, fatty acids showed persistent changes during the stress period. Elevated CO2 reduced the impact of stress on sugar and amino acid metabolism, but not on fatty acids. Integrating metabolite data with transcriptome results revealed that some of the metabolic changes were regulated at the transcriptional level. Multivariate analyses grouped metabolites on the basis of stress exposure time, indicating specificity in metabolic responses to short and prolonged stress. Taken together, the results indicate that dynamic metabolic reprograming plays an important role in plant acclimation to climatic extremes. The extent of such metabolic adjustments is less under high CO2, further pointing towards the role of high CO2 in stress mitigation. PMID- 29462347 TI - Long-term quality-of-care score predicts incident chronic kidney disease in patients with type 2 diabetes. AB - Background: Chronic kidney disease (CKD) is a common complication of diabetes, and requires long-term medical care. However, besides the blood glucose level, no reliable method is currently available to link the quality of care and the development of CKD. We therefore developed a long-term quality-of-care score for predicting the occurrence of CKD in patients with type 2 diabetes. Methods: In this retrospective cohort study, using Taiwan's Longitudinal Cohort of Diabetes Patients Database and the medical records in a medical center, we identified incident patients with type 2 diabetes during 1999-2003 and followed them until 2011. A quality-of-care score (from 0 to 8) was calculated according to process indicators (frequencies of HbA1c and lipid profile testing and urine, foot, and retinal examinations), intermediate outcome indicators (low-density lipoprotein, blood pressure, and HbA1c) and comorbidity of hypertension. We used Cox regression models to evaluate the association between the score and the incidence of CKD. Results: Of the 4754 patients enrolled, 1407 developed CKD after a mean follow-up of 9.06 years. Compared with the risk of developing a CKD event in patients with scores <=2, the risk was 69% lower in those with quality-of-care scores >=5 (hazard ratio [HR] 0.31; 95% confidence interval [CI] 0.25-0.40) and 33% lower in those with scores between 3 and 4 (HR 0.67; 95% CI 0.59-0.77). Conclusions: Good quality of care can reduce the risk of CKD in patients with type 2 diabetes. The score developed in this study had a significant association with the risk of CKD and thus can be applied to guide the care for these patients. PMID- 29462348 TI - Long-term follow-up of a combined rituximab and cyclophosphamide regimen in renal anti-neutrophil cytoplasm antibody-associated vasculitis. AB - Background: Current guidelines advise that rituximab or cyclophosphamide should be used for the treatment of organ-threatening disease in anti-neutrophil cytoplasm antibody (ANCA)-associated vasculitis (AAV), although few studies have examined the efficacy and safety of these agents in combination. Methods: We conducted a single-centre cohort study of 66 patients treated with a combination of oral corticosteroids, rituximab and low-dose pulsed intravenous cyclophosphamide followed by a maintenance regimen of azathioprine and tapered steroid for the treatment of biopsy-proven renal involvement in AAV. Patients were followed for a median of 56 months. Case-control analysis with 198 propensity-matched cases from European Vasculitis Study Group (EUVAS) trials compared long-term differences in relapse-free, renal and patient survival. Results: At entry, the median Birmingham Vasculitis Activity Score (BVAS) was 19 and estimated glomerular filtration rate was 25 mL/min. Cumulative doses of rituximab, cyclophosphamide and corticosteroids were 2, 3 and 4.2 g, respectively, at 6 months. A total of 94% of patients achieved disease remission by 6 months (BVAS < 0) and patient and renal survival were 84 and 95%, respectively, at 5 years. A total of 84% achieved ANCA-negative status and 57% remained B cell deplete at 2 years, which was associated with low rates of major relapse (15% at 5 years). The serious infection rate during long-term follow-up was 1.24 per 10 patient-years. Treatment with this regimen was associated with a reduced risk of death {hazard ratio [HR] 0.29 [95% confidence interval (CI) 0.125 0.675], P = 0.004}, progression to end-stage renal disease (ESRD) [HR 0.20 (95% CI 0.06-0.65), P = 0.007] and relapse [HR 0.49 (95% CI 0.25-0.97), P = 0.04] compared with propensity-matched patients enrolled in EUVAS trials. Conclusions: This regimen is potentially superior to current standards of care, and controlled studies are warranted to establish the utility of combination drug approaches in the treatment of AAV.

PMID- 29462351 TI - One-on-one care management and procurement of Naloxone for ambulatory use. AB - Background: Morbidity and mortality from prescription opioids has reached unprecedented levels. Opioids remain part of chronic pain treatment in primary care. This study was designed to determine whether one-on-one care management increases procurement of Naloxone, an opioid antagonist shown to reduce morbidity and mortality in opioid overdoses. Methods: Participants included all patients >=18 years enrolled in a primary care-based chronic pain management program and who were prescribed a daily dose of opioids for treatment of chronic pain. In total, 153 patients chose to participate. Each had a 1 h one-on-one education meeting with a registered nurse. Results: Among the enrolled, eight patients (5.2%) had procured Naloxone prior to intervention. Overall, 31 additional patients (20.2%) procured Naloxone after intervention, a 288% relative improvement in the attainment of Naloxone (P < 0.0001) (chi2 = 29.032 with 1 degree freedom). Of the 114 participants who never procured Naloxone, 69.3% believed it was unnecessary, 20% forgot about Naloxone, 8% said it was cost prohibitive, 3.5% had access concerns and 0.9% had concerns about side effects. Conclusion: Direct one-on-one nurse care management sessions were associated with an increased procurement of Naloxone in a primary care-based pain management program. A significant number of patients believed Naloxone was unnecessary after the intervention. PMID- 29462352 TI - Inhibition of corticosterone synthesis and its effect on acute phase proteins, heat shock protein 70, and interleukin-6 in broiler chickens subjected to feed restriction. AB - The aim of the current study was to elucidate whether inhibition of corticosterone (CORT) synthesis could modify stress response to feed deprivation and its possible interactions with feed restriction in the neonatal period in broiler chickens. Equal numbers of broiler chicks were subjected to either 60% feed restriction (60FR) or ad libitum (AL) on d 4, 5, and 6. On day 7, blood CORT, acute phase proteins (APP), interleukin-6 (IL-6) levels, and brain heat shock protein 70 (HSP70) expression were determined. On d 35, chickens in each early age feeding regimen were subjected to one of the following treatments: (i) ad libitum feeding (ALF), (ii) 24 h feed deprivation (SFR), or (iii) 24 h feed deprivation with intramuscular injection of 1,1-bis(4-chlorophenyl)-2,2,2 trichloroethane (DDT) at 100 mg/kg BW (SFR+DDT). The effect of SFR on CORT, APP, IL-6, and HSP 70 were determined on d 36. The results showed that subjecting chicks to 60FR significantly elevated CORT and brain HSP70 concentration compared to the AL group on d 7. The early feeding regimen had no significant effect on CORT, alpha-1 acid glycoprotein (AGP), ovotransferrin (OVT), ceruoplasmin (CP), IL-6, or brain HSP70 on d 36. The CORT, AGP, OVT, CP, IL-6, and brain HSP70 expression of SFR birds following 24 h of feed deprivation (d 36) were significantly higher than their ALF and SFR+DDT counterparts. Both ALF and SFR+DDT birds had similar values. Stress attributed to feed deprivation without concurrent increase in CORT had a negligible effect on serum levels of APP and IL 6 and brain HSP70 expression. PMID- 29462353 TI - Predicition models for delayed graft function: external validation on The Dutch Prospective Renal Transplantation Registry. AB - Background: Delayed graft function (DGF) is a common complication after kidney transplantation in the era of accepting an equal number of brain- and circulatory death donor kidneys in the Netherlands. To identify those cases with an increased risk of developing DGF, various multivariable algorithms have been proposed. The objective was to validate the reproducibility of four predictive algorithms by Irish et al. (A risk prediction model for delayed graft function in the current era of deceased donor renal transplantation. Am J Transplant 2010;10:2279-2286) (USA), Jeldres et al. (Prediction of delayed graft function after renal transplantation. Can Urol Assoc J 2009;3:377-382) (Canada), Chapal et al. (A useful scoring system for the prediction and management of delayed graft function following kidney transplantation from cadaveric donors. Kidney Int 2014;86:1130 1139) (France) and Zaza et al. (Predictive model for delayed graft function based on easily available pre-renal transplant variables. Intern Emerg Med 2015;10:135 141) (Italy) according to a novel framework for external validation. Methods: We conducted a prospective observational study with data from the Dutch Organ Transplantation Registry (NOTR). Renal transplant recipients from all eight Dutch academic medical centers between 2002 and 2012 who received a deceased allograft were included (N = 3333). The four prediction algorithms were reconstructed from donor, recipient and transplantation data. Their predictive value for DGF was validated by c-statistics, calibration statistics and net benefit analysis. Case mix (un)relatedness was investigated with a membership model and mean and standard deviation of the linear predictor. Results: The prevalence of DGF was 37%. Despite a significantly different case-mix, the US algorithm by Irish was best reproducible, with a c-index of 0.761 (range 0.756 - 0.762), and well calibrated over the complete range of predicted probabilities of having DGF. The US model had a net benefit of 0.242 at a threshold probability of 0.25, compared with 0.089 net benefit for the same threshold in the original study, equivalent to correctly identifying DGF in 24 cases per 100 patients (true positive results) without an increase in the number of false-positive results. Conclusions: The US model by Irish et al. was generalizable and best transportable to Dutch recipients with a deceased donor kidney. The algorithm detects an increased risk of DGF after allocation and enables us to improve individual patient management. PMID- 29462354 TI - Microdam Impoundments Provide Suitable Habitat for Larvae of Malaria Vectors: An Observational Study in Western Kenya. AB - Impoundments formed by microdams in rural areas of Africa are important sources of water for people, but they provide potential larval habitats for Anopheles (Diptera: Culicidae) mosquitoes that are vectors of malaria. To study this association, the perimeters of 31 microdam impoundments in western Kenya were sampled for Anopheles larvae in three zones (patches of floating and emergent vegetation, shorelines of open water, and aggregations of cattle hoofprints) across dry and rainy seasons. Of 3,169 larvae collected, most (86.8%) were collected in the rainy season. Of 2,403 larvae successfully reared to fourth instar or adult, nine species were identified; most (80.2%) were Anopheles arabiensis Patton, sampled from hoofprint zones in the rainy season. Other species collected were Anopheles coustani Laveran, Anopheles gambiae s.s. Giles, Anopheles funestus Giles, and Anopheles rivulorum Leeson, Anopheles pharoensis Theobald, Anopheles squamosus Theobald, Anopheles rufipes (Gough), and Anopheles ardensis (Theobald). Larvae of An. funestus were uncommon (1.5%) in both dry and rainy seasons and were confined to vegetated zones, suggesting that microdam impoundments are not primary habitats for this important vector species, although microdams may provide a dry season refuge habitat for malaria vectors, contributing to population persistence through the dry season. In this study, microdam impoundments clearly provided habitat for the malaria vector An. arabiensis in the rainy season, most of which was within the shallow apron side of the impoundments where people brought cattle for watering, resulting in compacted soil with aggregations of water-filled hoofprints. This observation suggests a potential conflict between public health concerns about malaria and people's need for stable and reliable sources of water. PMID- 29462355 TI - Small molecule modulator of protein disulfide isomerase attenuates mutant huntingtin toxicity and inhibits endoplasmic reticulum stress in a mouse model of Huntington's disease. AB - Huntington's disease (HD) is caused by a cytosine-adenine-guanine (CAG) trinucleotide repeat expansion in the huntingtin (HTT) gene encoding an elongated polyglutamine tract within the N-terminal of the huntingtin protein (Htt) and leads to Htt misfolding, aberrant protein aggregation, and progressive appearance of disease symptoms. Chronic activation of endoplasmic reticulum (ER) stress by mutant Htt (mHtt) results in cellular dysfunction and ultimately cell death. Protein disulfide isomerase (PDI) is a chaperone protein located in the ER. Our previous studies demonstrated that mHtt caused PDI to accumulate at mitochondria associated ER membranes and triggered cell death, and that modulating PDI activity using small molecules protected cells again mHtt toxicity in cell and brain slice models of HD. In this study, we demonstrated that PDI is upregulated in the HD human brain, in cell and mouse models. Chronic administration of a reversible, brain penetrable small molecule PDI modulator, LOC14 (20 mg/kg/day), significantly improved motor function, attenuated brain atrophy and extended survival in the N171-82Q HD mice. Moreover, LOC14 preserved medium spiny neuronal marker dopamine- and cyclic-AMP-regulated phosphoprotein of molecular weight 32 000 (DARPP32) levels in the striatum of HD mice. Mechanistic study revealed that LOC14 suppressed mHtt-induced ER stress, indicated by repressing the abnormally upregulated ER stress proteins in HD models. These findings suggest that LOC14 is promising to be further optimized for clinical trials of HD, and modulation of signaling pathways coping with ER stress may constitute an attractive approach to reduce mHtt toxicity and identify new therapeutic targets for treatment of HD. PMID- 29462356 TI - Nutrient Fortification of Human Donor Milk Affects Intestinal Function and Protein Metabolism in Preterm Pigs. AB - Background: Nutrient fortification of human milk is often required to secure adequate growth and organ development for very preterm infants. There is concern that formula-based fortifiers (FFs) induce intestinal dysfunction, feeding intolerance, and necrotizing enterocolitis (NEC). Bovine colostrum (BC) may be an alternative nutrient fortifier, considering its high content of protein and milk bioactive factors. Objective: We investigated whether BC was superior to an FF product based on processed bovine milk and vegetable oil to fortify donor human milk (DHM) for preterm pigs, used as a model for infants. Methods: Sixty preterm pigs from 4 sows (Danish Landrace * Large White * Duroc, birth weight 944 +/- 29 g) received decreasing volumes of parenteral nutrition (96-72 mL ? kg-1 ? d-1) and increasing volumes of enteral nutrition (24-132 mL ? kg-1 ? d-1) for 8 d. Pigs were fed donor porcine milk (DPM) and DHM with or without FF or BC fortification (+4.6 g protein ? kg-1 ? d-1). Results: DPM-fed pigs showed higher growth (10-fold), protein synthesis (+15-30%), villus heights, lactase and peptidase activities (+30%), and reduced intestinal cytokines (-50%) relative to DHM pigs (all P < 0.05). Fortification increased protein synthesis (+20-30%), but with higher weight gain and lower urea and cortisol concentrations for DHM+BC compared with DHM+FF pigs (2- to 3-fold differences, all P <= 0.06). DHM+FF pigs showed more diarrhea and reduced lactase and peptidase activities, hexose uptake, and villus heights relative to DHM+BC or DHM pigs (30-90% differences, P < 0.05). Fortification did not affect NEC incidence but DHM+BC pigs had lower colonic interleukin (IL)-6 and IL-8 concentrations relative to the remaining pigs (-30%, P = 0.06). DHM+FF pigs had higher stomach bacterial load than did DHM, and higher bacterial density along intestinal villi than did DHM and DHM+BC pigs (2- to 3 fold, P < 0.05). Conclusions: The FF product investigated in this study reduced growth, intestinal function, and protein utilization in DHM-fed preterm pigs, relative to BC as fortifier. The relevance of BC as an alternative nutrient fortifier for preterm infants should be tested. PMID- 29462358 TI - Erratum. PMID- 29462357 TI - NICE public health guidance update. PMID- 29462359 TI - Privatization in the Irish hospital sector since 1980. AB - Background: Privatization has transformed health care systems over the last several decades. This article examines trends in bed supply in Ireland between 1980 and 2015 within the context of government policy on bed provision in a system of inequitable access to care. Ireland has not published bed data on private hospitals since the 1980s, even if they comprise about one-quarter of all hospitals. However, this article presents, for the first time, annual bed data since the 1980s collected from private hospitals and used to trace the evolution of bed supply over time. Methods: Bed data were collected for private Irish hospitals for the years 1980-2015, mainly through direct requests to hospitals. Additional sources included the Irish Medical Directory, private health insurance data, hospital company records and newspaper archives. Results: Subject to data caveats explained in the article, between 1980 and 2015, total inpatient beds decreased by 25.5% nationally. Inpatient bed numbers in private for-profit (PFP) hospitals rose from 0 to 1075 but decreased from 9601 to 5216 in private not-for profit (PNFP) hospitals and from 7028 to 6092 in public hospitals (using the Irish hospital classification, beds in private hospitals increased from 1518 to 1910 but decreased from 15 111 to 10 473 in public hospitals). Also, by 2015, 24.1% of PFP hospital beds were day beds, compared to 17.7% for PNFP and 15.7% for public hospitals (using the Irish classification, by 2015, day beds accounted for 23.8% of beds in private hospitals and 16.1% in public hospitals). Conclusions: Trends in bed supply in Ireland between 1980 and 2015 are documented empirically for all Irish acute hospitals and contextualized within government policy on bed provision. The Irish acute hospital system has experienced privatization reforms supported by the government over the last several decades. PMID- 29462360 TI - Effects of fatty acid glyceride product SILOhealth 104 on the growth performance and carcass composition of broiler chickens. AB - Butyric acid is the primary energy source for colonocytes, and has shown potential as an alternative to in-feed antibiotics, due to its antimicrobial activity and positive effects on production performance traits of broiler chickens. SILOhealth 104 (SILO S.P.A., Florence, Italy) is a commercial product mainly containing mono- and di-glycerides of butyrate with a small portion of propionic, caprylic, capric, and lauric acid mono- and di-glycerides. Its effects on broiler performance and carcass composition have yet to be evaluated. Four hundred-eighty day-old male Ross 308 birds were divided into different dietary treatment groups with equal starting weights and fed a diet containing 0, 500, 1,000, 2,000, or 3,000 ppm of SILOhealth 104 for 35 days. There were no significant differences in overall average daily gain or feed: gain ratio with the addition of SILOhealth 104 to the diets (P > 0.05). At 5 wk of age, abdominal fat weight was reduced in birds supplemented with SILOhealth 104 in a dose responsive manner (P < 0.05), while breast muscle weight increased with supplementation, with significant increases in 2,000 ppm and 3,000 ppm birds compared to controls (P < 0.05). A significant reduction in gene expression of both forkhead box protein O4 and myostatin, 2 factors that can inhibit protein synthesis, was found in the breast muscle of all SILOhealth 104 treated birds (P < 0.05). In addition, gene expression in the adipose tissue, including acetyl-CoA carboxylase alpha and lipoprotein lipase, which are associated with lipid metabolism, was significantly decreased and increased, respectively, by the supplementation of SILOhealth 104 (P < 0.05). These data suggest that the components of SILOhealth 104 can positively affect the deposition of muscle, while reducing abdominal fat deposition in broiler chickens. PMID- 29462361 TI - Wet feed and cold water as heat stress modulators in growing Muscovy ducklings. AB - In an attempt to alleviate the deleterious effects of high summer temperatures, the present study investigated the effects of wet feed and cold water on the growth performance, carcass and meat quality, leg problems, physiological responses, and blood parameters of growing Muscovy ducklings. A total of 180 4 week-old ducklings was randomly divided into 6 experimental groups in a 3 * 2 factorial design that included 3 feed systems (AD: ad libitum dry; DW: diurnal wet; and AW: ad libitum wet) and 2 systems of water (TW: tap water; and CW: cold water). Access to wet feed and cold water affected the growth performance, dressed carcass, gizzard, meat quality (tenderness, juiciness, and susceptibility), tonic immobility, body temperature, and blood parameters [albumin: globulin (A: G) ratio and levels of glucose, alanine transferase (ALT), total antioxidant capacity (T-AOC), and malondialdehyde (MDA)] of the ducklings but had no significant effect on plumage condition, shank length, keel bone length, leg problems, or breast blisters. The body weight (BW) of the DW group was 1.97 and 3.12% greater than that of the AD and AW groups, respectively, and the BWG of the DW group was 6.91 and 10.72% greater than that of the AD and AW groups, respectively. Therefore, providing access to wet feed and cold water is highly recommended when raising Muscovy ducks in open houses under high temperature conditions. PMID- 29462362 TI - Postoperative Delirium in Glioblastoma Patients: Risk Factors and Prognostic Implications. AB - BACKGROUND: Delirium is a postoperative neurological morbidity in glioblastoma whose risk factors, incidence, and prognostic implications remain undefined. OBJECTIVE: To develop an algorithm using preoperative factors to predict postoperative delirium. METHODS: Retrospective analysis of 554 consecutive patients (mean age = 61.5 yr; 42% female) undergoing first glioblastoma procedure at our institution 2005 to 2011. RESULTS: Postoperative delirium occurred in 7% of patients (n = 38). Patients undergoing biopsy (10%; n = 54) did not experience delirium. In patients undergoing resection (n = 500), multivariate logistic regression identified 5 factors independently predicting postoperative delirium: age, chronic pulmonary disease, psychiatric history, bihemispheric tumors, and tumor size. We developed a score function entitled "GRAD" (Glioblastoma Risk Assessment for Delirium) to stratify patients into risk categories by assigning point(s) to each preoperative factor based on the relative magnitude of its regression coefficient. Point totals were summed for each patient: patients with 0 to 2 (n = 227) and 3 to 7 (n = 221) points were designated as low and high risk with postoperative delirium rates of 2% vs 15%, respectively (chi-square; P < .001), with the model validated using a separate patient cohort. Postoperative delirium lengthened hospital stays (P < .001), decreased likelihood of discharge home (P < .001), and was independently associated with decreased survival (4.5 vs 13.4 mo; hazard ratio = 1.9 [1.2-2.8]) in multivariate analysis. CONCLUSION: We developed a model to predict development of postoperative delirium using 2 tumor specific (bihemispheric tumors and tumor size) and 3 patient-specific (age, psychiatric history, and chronic pulmonary disease) factors. High-risk patients and their families should be counseled preoperatively, and this risk could be considered in the choice of biopsy vs resection, and resection patients should be monitored closely postoperatively. PMID- 29462363 TI - A Gene Regulatory Network for Cellular Reprogramming in Plant Regeneration. AB - Wounding triggers organ regeneration in many plant species, and application of plant hormones, such as auxin and cytokinin, enhances their regenerative capacities in tissue culture. Recent studies have identified several key players mediating wound- and/or plant hormone-induced cellular reprogramming, but the global architecture of gene regulatory relationships underlying plant cellular reprogramming is still far from clear. In this study, we uncovered a gene regulatory network (GRN) associated with plant cellular reprogramming by using an enhanced yeast one-hybrid (eY1H) screen systematically to identify regulatory relationships between 252 transcription factors (TFs) and 48 promoters. Our network analyses suggest that wound- and/or hormone-invoked signals exhibit extensive cross-talk and regulate many common reprogramming-associated genes via multilayered regulatory cascades. Our data suggest that PLETHORA 3 (PLT3), ENHANCER OF SHOOT REGENERATION 1 (ESR1) and HEAT SHOCK FACTOR B 1 (HSFB1) act as critical nodes that have many overlapping targets and potentially connect upstream stimuli to downstream developmental decisions. Interestingly, a set of wound-inducible APETALA 2/ETHYLENE RESPONSE FACTORs (AP2/ERFs) appear to regulate these key genes, which, in turn, form feed-forward cascades that control downstream targets associated with callus formation and organ regeneration. In addition, we found another regulatory pathway, mediated by LATERAL ORGAN BOUNDARY/ASYMMETRIC LEAVES 2 (LOB/AS2) TFs, which probably plays a distinct but partially overlapping role alongside the AP2/ERFs in the putative gene regulatory cascades. Taken together, our findings provide the first global picture of the GRN governing plant cell reprogramming, which will serve as a valuable resource for future studies.

AB - The pharmacokinetic profile of oral cocaine has not been fully characterized and prospective data on oral bioavailability are limited. A within-subject study was performed to characterize the bioavailability and pharmacokinetics of oral cocaine. Fourteen healthy inpatient participants (six males) with current histories of cocaine use were administered two oral doses (100 and 200 mg) and one intravenous (IV) dose (40 mg) of cocaine during three separate dosing sessions. Plasma samples were collected for up to 24 h after dosing and analyzed for cocaine and metabolites by gas chromatography-mass spectrometry. Pharmacokinetic parameters were calculated by non-compartmental analysis, and a two-factor model was used to assess for dose and sex differences. The mean +/- SEM oral cocaine bioavailability was 0.32 +/- 0.04 after 100 and 0.45 +/- 0.06 after 200 mg oral cocaine. Volume of distribution (Vd) and clearance (CL) were both greatest after 100 mg oral (Vd = 4.2 L/kg; CL = 116.2 mL/[min kg]) compared to 200 mg oral (Vd = 2.9 L/kg; CL = 87.5 mL/[min kg]) and 40 mg IV (Vd = 1.3 L/kg; CL = 32.7 mL/[min kg]). Oral cocaine area-under-thecurve (AUC) and peak concentration increased in a dose-related manner. AUC metabolite-to-parent ratios of benzoylecgonine and ecgonine methyl ester were significantly higher after oral compared to IV administration and highest after the lower oral dose. In addition, minor metabolites were detected in higher concentrations after oral compared to IV cocaine. Oral cocaine produced a pharmacokinetic profile different from IV cocaine, which appears as a rightward and downward shift in the concentration time profile. Cocaine bioavailability values were similar to previous estimates. Oral cocaine also produced a unique metabolic profile, with greater concentrations of major and minor metabolites.

AB - BACKGROUND: Cavernous malformations (CMs) are congenital malformations and may be located anywhere in the brain. We present a series of CMs located close to or inside of the motor-sensory cortex or corticospinal tract (CST) with clinical onset due to hemorrhage or mass effect. In such cases, surgery becomes an acceptable option. OBJECTIVE: To evaluate the role of diffusion tensor imaging (DTI), functional-magnetic-resonance imaging (fMRI), intraoperative neurophysiological monitoring, neuronavigation, and brain-mapping and the clinical results of surgical treatment of CMs in this critical location. METHODS: The study included 54 patients harboring 22 cortical and 32 deep locations. This series was distinct because in group I, where the DTI was not obtained, and in the group II, where this evaluation was performed. RESULTS: The postoperative permanent morbidity rate was 4% in the historical group for the deeper CMs, and there was no morbidity in the second group. DTI and fMRI permitted us to estimate the distance between the CMs and both the cortical activation cluster and the pyramidal tract. These data, in addition to intraoperative mapping and monitoring, made it necessary for us to perform a partial resection in 2 cases in the second series. CONCLUSION: CMs are congenital lesions and CST fibers can run directly on their surface. Integration of fMRI and DTI data with intraoperative functional monitoring and direct cortical and subcortical mapping are mandatory to accomplish an optimal resection, tailoring the best surgical approach to the acceptable morbidity. A subtotal resection could be considered an option for deep locations. PMID- 29462366 TI - PHYSICAL CHARACTERISATION OF FOUR DIFFERENT COMMERCIAL DIGITAL BREAST TOMOSYNTHESIS SYSTEMS. AB - The aim of this article was to characterise the performance of four different digital breast tomosynthesis (DBT) systems in terms of dose and image quality parameters. One of them, GE Pristina, has never been tested before. Average glandular doses were measured both in DBT and 2D full field digital mammography mode. Several phantoms were employed to perform signal difference to noise ratio, slice sensitivity profile, slice to slice incrementation, chest wall offset, z axis geometry, artefact spread function, low contrast detectability, contrast detail evaluations, image uniformity and in-plane MTF in chest wall-nipple and in tube-travel directions. There are many differences in DBT systems explored: the angular range, detector type, reconstruction algorithms, and the presence or not of the grid. Even if it is not simple to calculate a global figure of merit, the analysis of all the collected data can be useful in a contest of a quality assurance program to define a set of values that could be used as benchmarks. PMID- 29462367 TI - Expression of angiogenic factors and plexiform lesions in the lungs of broiler and layer chickens: A comparison. AB - Plexiform lesions are characteristic histological changes of pulmonary arteries in human patients with severe pulmonary arterial hypertension (PAH) and are regarded as angiogenic lesions. Meat-type broiler chickens are susceptible to PAH and can develop plexiform lesions spontaneously. Whether the lesion development in broilers is associated with PAH predisposition and lung angiogenic environment remains unclear. Moreover, little is known about the cellular origin of these structures. In this work, plexiform lesions were detected in both layer chickens (a strain known to be resistant to PAH) and broiler chickens aged between 1 and 6 wk with normal pulmonary arterial pressures. Within each of the sampled ages, the lesion density did not differ between strains, with an exception of wk 4 when broiler was higher than layer. In contrast to the trend of age-related decline in layers, lesion densities in broilers demonstrated bi-phasic alterations characterized by a gradual decrease during wk 1 to 3 followed by a sudden increase at wk 4. The mRNA of 6 angiogenic factors in the lung tissue, namely, vascular endothelial growth factor receptor (VEGFR)-2, angiopoietin (Ang)-1, angiopoietin receptor Tie-2, transforming growth factor (TGF)-beta1, hepatocyte growth factor (HGF), and interleukin (IL)-8, were differentially expressed between strains. However, none of them was found to be significantly correlated with the lesion density by strain and age-adjusted partial correlation analysis. An in vivo experiment revealed impaired differentiation of endothelial progenitor cells (EPC) into endothelial cells during the producing of plexiform lesions, as evidenced by increased expression of endothelial CD133, a maker of EPC, but reduced expression of CD31, a marker of mature endothelial cells, in the parent vessels of plexiform lesions compared to normal vessels. Collectively, it appears unlikely that the predisposition to PAH or intrapulmonary angiogenic environment contributes to the lesion development in broilers when compared with layers. It is suggested that the lesion development is associated with increased pulmonary arterial pressure, and that local EPC dysfunction may play a role in the process. PMID- 29462368 TI - Dural Cells Release Factors Which Promote Cancer Cell Malignancy and Induce Immunosuppressive Markers in Bone Marrow Myeloid Cells. AB - BACKGROUND: Thirty per cent of cancer patients develop spine metastases with a substantial number leading to spinal cord compression and neurological deficits. Many demonstrate a propensity toward metastasis to the posterior third of the vertebral body. The dura, the outer layer of the meninges, lies in intimate contact with the posterior border of the vertebral body and has been shown to influence adjacent bone. The effects of the dura on bone marrow and cancer cells have not been examined. Understanding the biology of spinal metastasis will provide insights into mechanisms of cancer growth and allow for new treatment strategies. OBJECTIVE: To examine the extent to which dura influences bone marrow/tumor cell metastatic characteristics. METHODS: Dura conditioned media (DCM) from primary dura was examined for the ability to stimulate tumor cell proliferation/invasion and to alter bone marrow cell populations. RNA sequencing of dural fibroblasts was performed to examine expression of cytokines and growth factors. RESULTS: DCM induced a significant increase in invasion and proliferation of multiple tumor cell lines, and of patient-derived primary spinal metastatic cells. DCM also increased the proliferation of bone marrow myeloid cells, inducing expression of immunosuppressive markers. RNA sequencing of dural fibroblasts demonstrated abundant expression of cytokines and growth factors involved in cancer/immune pathways. CONCLUSION: Factors released by primary dural cells induce proliferation of tumor cells and alter bone marrow to create a fertile environment for tumor growth. The dura therefore may play an important role in the increased incidence of metastases to adjacent bone. PMID- 29462369 TI - CYP17 gene plays a key role in goose genital growth by influencing the testosterone level at puberty. AB - All birds reproduce by internal fertilization, but only 3% of birds have external genitalia. Hormone secretions and body size influence genital growth, but the actual regulatory mechanism is rarely reported. Thus, using 35 geese as experimental material, the regulatory mechanism of goose external genitalia growth was explored by measuring body size parameters, serum hormone concentrations, and related gene expression. In this study, genital growth was different among tested geese, but histological and morphological results showed that all geese external genitalia contained complete tissues. Measurements of hormone levels showed that at puberty, as the genital length increased, irregular decreases were observed in the levels of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), whereas an irregular increase was observed in the levels of testosterone (T); furthermore, the levels of testosterone (T) gradually increased to a peak at 34 weeks. Based on RT-PCR results, as the genital length increased, only the expression of 17alpha-hydroxylase/17, 20-lyase (CYP17) mRNA slightly decreased at first, and then significantly increased to a peak, whereas the expression patterns of other genes were irregular. Furthermore, the CYP17 immunohistochemistry results also showed a pattern that was highly consistent with the patterns of mRNA expression and T secretion. In addition, based on body measurements, as body weight increased, the genital length increased. Thus, these results suggested that the CYP17 gene plays a key role in goose genital growth. PMID- 29462370 TI - The effect of Eimeria maxima infection on the expression of amino acid and sugar transporters aminopeptidase, as well as the di- and tri-peptide transporter PepT1, is not solely due to decreased feed intake. AB - Coccidiosis caused by Eimeria in poultry is endemic to poultry operations and results in decreased feed intake, diarrhea, and decreased weight gain. The goal was to determine the effect of Eimeria maxima infection on the expression of genes that encode peptide and amino acid transporters (AATs), and also to determine whether decreased feed intake contributes to the change in gene expression by including a pair-fed group of broilers. Three groups of male Ross broilers: 1) not infected, 2) infected, and 3) not infected pair-fed groups were used. Chicks were infected with 1,000 oocysts of E. maxima at 21 d of age. Feed consumption was obtained daily, and at d 0, 3, 5, 7, 10, and 14 post-infection (PI), 6 birds were euthanized, and a portion of the jejunum was removed for qRT PCR. Infected birds had significantly decreased feed consumption between d 6 to 9 PI. At d 7 PI infected birds had a 45% reduction in weight gain, and pair-fed birds had a 32% reduction in weight gain. The feed conversion ratio at d 7 PI of infected birds was 2.2 while that of pair-fed birds was 1.7, compared to 1.5 in uninfected birds. Growth parameters were more affected in infected birds than in pair-fed birds. By measuring expression levels of nutrient uptake and processing genes via qRT-PCR, it was determined that genes encoding proteins located at the brush border of the gut epithelium were affected by infection as well as change in feed intake. The expression of AATs B degrees AT, b degrees ,+AT, EAAT3, and PepT1 in infected birds decreased sharply at the height of infection; however, in birds that were pair fed, an increase in expression of b degrees ,+AT, and PepT1 was observed, and little change was seen in expression of B degrees AT and EAAT3. In summary, the changes in expression of digestive enzymes and nutrient transporters are distinct between coccidia-infected birds compared to healthy pair-fed birds. PMID- 29462371 TI - Ultrastructural diversity between centrioles of eukaryotes. AB - Several decades of centriole research have revealed the beautiful symmetry present in these microtubule-based organelles, which are required to form centrosomes, cilia and flagella in many eukaryotes. Centriole architecture is largely conserved across most organisms; however, individual centriolar features such as the central cartwheel or microtubule walls exhibit considerable variability when examined with finer resolution. In this paper, we review the ultrastructural characteristics of centrioles in commonly studied organisms, highlighting the subtle and not-so-subtle differences between specific structural components of these centrioles. In addition, we survey some non-canonical centriole structures that have been discovered in various species, from the coaxial bicentrioles of protists and lower land plants to the giant irregular centrioles of the fungus gnat Sciara. Finally, we speculate on the functional significance of these differences between centrioles, and the contribution of individual structural elements such as the cartwheel or microtubules towards the stability of centrioles. PMID- 29462372 TI - Moving Second Courses of Radiotherapy Forward: Early Re-Irradiation After Surgical Resection for Recurrent Gliomas Improves Efficacy With Excellent Tolerability. AB - BACKGROUND: Generally, re-irradiation (Re-RT) is offered to patients with glioma recurrences with macroscopic lesions. Results are discussed controversially, and some centers postulate limited benefit of Re-RT. Re-RT is generally offered to tumors up to 4 cm in diameter. Re-resection is also discussed controversially; however, recent studies have shown significant benefit. OBJECTIVE: To combine proactive re-resection and early Re-RT in patients with recurrent glioma. METHODS: We included 108 patients treated between 2002 and 2016 for recurrent glioma. All patients underwent surgical resection for recurrence; Re-RT was applied with a median dose of 37.5 Gy (range 25 Gy-57Gy/equivalent dose in 2Gy fractions [EQD2]) with high-precision techniques. All patients were followed prospectively in an interdisciplinary follow-up program. RESULTS: Median follow up after Re-RT was 7 mo. Median survival after surgery and Re-RT was 12 mo (range 1-102 mo). Complete resection had a significant impact on the outcome (P = .03). The strongest predictors of outcome were MGMT-promotor methylation and Karnofsky Performance Score and time interval between primary and second RT. CONCLUSION: Proactive resection of tumor recurrences combined with early Re-RT conveys into promising outcome in recurrent glioma. Complete resection and early Re-RT lead to improved survival. Thus, moving Re-RT to an earlier timepoint during the treatment of recurrent glioma, eg after complete macroscopic removal of the tumor, may be crucial for treatment optimization. Using advanced RT techniques, side effects are low. Currently, this concept is evaluated in the GLIOCAVE/NOA 17 trial. PMID- 29462373 TI - The Role of Matrix Metalloproteinase-3 in the Doxycycline Attenuation of Intracranial Venous Hypertension-Induced Angiogenesis. AB - BACKGROUND: The molecular mechanism of brain arteriovenous malformation (BAVM) is largely unknown. Intracranial venous hypertension (VH) may enhance focal angiogenesis and promote BAVM development and progression. A rat VH model effectively simulates the hemodynamic microenvironment of this disease. OBJECTIVE: To explore the effect of doxycycline in VH-related angiogenesis, as well as the role of matrix metalloproteinase-3 (MMP-3) and other molecular factors. METHODS: A rat VH model was generated by common carotid artery and distal external jugular vein anastomosis. Microvessel density (MVD) in the perisinus area and expression of MMP-3/2/9, VEGF, TIMP-1, TGF-beta, and HIF 1alpha were examined, with and without daily doxycycline treatment for 4 wk. The effects of doxycycline were verified in Vitro using human brain microvascular endothelial cells (HBMECs). MMP-3 overexpression or knockdown in HBMECs was used to confirm the role of MMP-3 in cell functions. RESULTS: MVD in the perisinus cortex was greatly increased after VH. Doxycycline decreased MVD, suppressed MMP 3 overexpression, and reduced VEGF, TGF-beta, and TIMP-1 levels compared with the controls (P < .05). In Vitro, doxycycline decreased HBMEC migration, tube formation, and the mRNA, protein, and enzymatic activity levels of MMP-3. MMP-3 overexpression in HBMECs promoted migration, while knockdown of MMP-3 significantly attenuated proliferation, migration, and tube formation (P < .05). CONCLUSION: Our findings indicate that MMP-3 plays an important role in VH related angiogenesis and the promotion of vascular remodeling. Suppression of MMP 3 overexpression by doxycycline may provide a potential strategy for inhibiting BAVM development.

PMID- 29462375 TI - Effects of Ginkgo biloba leaves (Ginkgo biloba) and Ginkgo biloba extract on nutrient and energy utilization of broilers. AB - An experiment using 112 21-day-old male Arbor Acres broilers that were randomly allocated to 7 treatments with 8 replicates in a completely randomized design was conducted to assess the effects of Ginkgo biloba leaves (Ginkgo biloba, GL) and Ginkgo biloba extract (EGB) on utilization of nutrients of broiler chickens. The dietary treatments were corn-soybean meal based diets: 1) T1, control diet; 2) T2, T1 + 20 g/kg GL; 3) T3, T1 + 40 g/kg GL; 4) T4, T1 + 60 g/kg GL; 5) T5, T1 + 0.4 g/kg EGB; 6) T6, T1 + 0.8 g/kg EGB; and 7) T7, T1 + 1.2 g/kg EGB. Endogenous losses were obtained from another 16 broilers. Excreta samples were collected to analyze the dry matter (DM), organic matter (OM), ether extract (EE), crude protein (CP), gross energy (GE), and amino acids (AA), and GE was analyzed for computation of AME and TME. As compared with those of the control treatment, the apparent digestibility (AD) and true digestibility (TD) of EE, CP, Thr, Val, Ile, Leu, Phe, Lys, His, and Arg were quadratically (P < 0.05) increased; moreover, the AD and TD of Met was linearly (P < 0.05) increased as the concentration of the EGB in the diet increased. Increasing GL from 0 to 60 g/kg of diet linearly (P < 0.05) increased the AD and TD of EE, Thr, Val, Leu, His, and Met and tended (0.05 < P < 0.1) to increase the TME, TMEn, and Arg. Supplementation of EGB increased (P < 0.05) AD and TD of EE, Thr, Val, Ile, Leu, Phe, His, and Arg and tended (0.05 < P < 0.1) to increase Lys as compared with those in the GL supplemented groups. Dietary supplementation of GL and EGB improved the utilization of nutrients of broiler chickens in a dose-dependent manner, and the optimum supplementation levels of GL or EGB in the diet of broilers was 60 or 0.8 g/kg of diet, respectively.

AB - The present work reports data of the radiation exposure to the patient in various diagnostic and therapeutic interventional radiological (IR) procedures. The study includes 260 diagnostic and 195 therapeutic exposure data in 455 IR procedures. All the IR procedures were performed on a biplane angiographic machine in a tertiary care hospital. The radiation exposure was estimated from dose-area product (DAP), fluoroscopy time (FT), number of fluoroscopic runs, number of images and cumulative dose (CD) value recorded during the procedure. The data reported in the present study show significant variability in DAP values in diagnostic and therapeutic IR procedures. In diagnostic procedures, the minimum median DAP value is 8.93 Gy cm2 for upper limb angiography with mean FT of 2.7 min and maximum DAP value is 108.8 Gy cm2 for inferior vena cava angiography with mean FT of 12.55 min. For therapeutic procedures, the median value of DAP ranges from 2.43 Gy cm2 for sclerotherapy with mean FT 0.65 min to 267.23 Gy cm2 for coiling of cerebral aneurysm with mean FT of 60.52 min. The DAP value for each procedure was also correlated with FT, number of fluoroscopic runs, number of images and CD. The reported DAP values in this study are within the range of earlier published results which suggest that our finding provides at least approximate applicability to other hospitals. The third quartile DAP values of the procedures having significant number of patient data (n >= 10) serves as provisional reference values for the optimization of procedure protocols.

PMID- 29462379 TI - A Cross-Talk Between Microbiota-Derived Short-Chain Fatty Acids and the Host Mucosal Immune System Regulates Intestinal Homeostasis and Inflammatory Bowel Disease. AB - Gut microbiota has a fundamental role in the energy homeostasis of the host and is essential for proper "education" of the immune system. Intestinal microbial communities are able to ferment dietary fiber releasing short-chain fatty acids (SCFAs). The SCFAs, particularly butyrate (BT), regulate innate and adaptive immune cell generation, trafficing, and function. For example, BT has an anti inflammatory effect by inhibiting the recruitment and proinflammatory activity of neutrophils, macrophages, dendritic cells, and effector T cells and by increasing the number and activity of regulatory T cells. Gut microbial dysbiosis, ie, a microbial community imbalance, has been suggested to play a role in the development of inflammatory bowel disease (IBD). The relationship between dysbiosis and IBD has been difficult to prove, especially in humans, and is probably complex and dynamic, rather than one of a simple cause and effect relationship. However, IBD patients have dysbiosis with reduced numbers of SCFAs producing bacteria and reduced BT concentration that is linked to a marked increase in the number of proinflammatory immune cells in the gut mucosa of these patients. Thus, microbial dysbiosis and reduced BT concentration may be a factor in the emergence and severity of IBD. Understanding the relationship between microbial dysbiosis and reduced BT concentration to IBD may lead to novel therapeutic interventions. PMID- 29462380 TI - Accelerated Infliximab Dosing Increases 30-Day Colectomy in Hospitalized Ulcerative Colitis Patients: A Propensity Score Analysis. AB - Background: Standard outpatient induction dosing of infliximab (IFX) may not be effective in hospitalized ulcerative colitis (UC) patients with higher inflammatory burden and colectomy risk. Our aim was to determine whether initial IFX induction dose affects 30-day colectomy rate and other disease-related outcomes. Methods: IFX-naive hospitalized UC patients receiving at least 1 inpatient 5 mg/kg (SD) or 10 mg/kg (HD) IFX induction dose were included. Baseline demographics and admission-related characteristics were documented. Propensity score based matching was used to control for provider bias introduced due to nonprotocolized choice of IFX dose. The primary outcome was 30-day colectomy; secondary outcomes included the need for an accelerated induction IFX (AD), length of stay (LOS), 90-day and 1-year colectomy, and complications. Results: Of 146 (120 SD/26 HD) patients included, 25 (17.1%) underwent colectomy by 30 days, 33 (22.6%) by 90 days, and 41 (28.1%) by 1 year. In 21 propensity score matched dyads (n = 42) treated with SD or HD, colectomy rates and LOS were similar. SD patients more often needed AD (23.8% vs. 0%, P = 0.048) and AD patients progressed to colectomy more rapidly within 30 days compared to non-AD (P = 0.001). Female sex and hypoalbuminemia were associated with significantly increased odds of needing AD on both univariate and multivariate analyses. Conclusions: In our propensity score based analysis, receiving accelerated IFX dosing after an initial SD infusion was associated with significantly higher 30 day colectomy rates in hospitalized acute UC patients. The most effective dosing strategy in this population remains unclear and prospective randomized studies are needed. PMID- 29462381 TI - Restorative Surgery in Patients With Primary Sclerosing Cholangitis and Ulcerative Colitis Following a Colectomy. AB - Background: Studies on surgical procedures in patients with concomitant primary sclerosing cholangitis (PSC) and ulcerative colitis (UC) have mainly been restricted to single centers. The aim was to compare surgical treatment of UC with or without PSC in a nationwide study. Methods: A cohort study including all patients diagnosed with UC between 1987 and 2014 in Sweden was undertaken. The impact of PSC on the risk of colectomy, the chance of restorative surgery, and risk of failure (presence of a stoma) following restorative surgery were estimated. Survival analyses were performed using the Kaplan-Meier method and multivariable Cox regression models. Results: Of 49 882 UC patients, 2079 had a PSC diagnosis at the end of follow-up. The risk of colectomy was unaffected by PSC diagnosis, whereas the chance of restorative surgery was elevated in PSC-UC patients (hazard ratio [HR], 1.22; 95% confidence interval [CI], 1.02-1.44). Ileorectal anastomosis (IRA) was performed in 63% of the PSC-UC patients and 43% of the non-PSC-UC-patients, and the corresponding numbers for ileal pouch anal anastomosis (IPAA) were 35% and 53%. There was no significantly increased risk of failure following restorative surgery in PSC patients (HR, 1.44; 95% CI, 0.93 2.22). In PSC-UC patients, the cumulative failure rates following an IRA at 3 and 5 years were 15% and 18%, and following an IPAA they were 11% and 18%, respectively. Conclusions: Presence of PSC is not associated with the risk of colectomy, whereas the chance of restorative surgery in PSC-UC patients is higher than in UC alone. PMID- 29462382 TI - Prediagnostic Serum Vitamin D Levels and the Risk of Crohn's Disease and Ulcerative Colitis in European Populations: A Nested Case-Control Study. AB - Background: A low vitamin D status has been put forward as a potential risk factor for the development of inflammatory bowel disease (IBD). This study investigated the association between prediagnostic circulating vitamin D concentrations and dietary intakes of vitamin D, and the risk of Crohn's disease (CD) and ulcerative colitis (UC). Methods: Among 359,728 participants of the European Prospective Investigation into Cancer and Nutrition cohort, individuals who developed CD or UC after enrollment were identified. Each case was matched with2 controls by center, gender, age, date of recruitment, and follow-up time. At cohort entry, blood samples were collected and dietary vitamin D intakes were obtained from validated food frequency questionnaires. Serum 25-hydroxyvitamin D levels were measured using liquid chromatography-tandem mass spectrometry. Conditional logistic regression was performed to determine the odds of CD and UC. Results: Seventy-two participants developed CD and 169 participants developed UC after a median follow-up of 4.7 and 4.1 years, respectively. Compared with the lowest quartile, no associations with the 3 higher quartiles of vitamin D concentrations were observed for CD (p trend = 0.34) or UC (p trend = 0.66). Similarly, no associations were detected when serum vitamin D levels were analyzed as a continuous variable. Dietary vitamin D intakes were not associated with CD (p trend = 0.39) or UC (p trend = 0.83). Conclusions: Vitamin D status was not associated with the development of CD or UC. This does not suggest a major role for vitamin D deficiency in the etiology of IBD, although larger studies are needed to confirm these findings. PMID- 29462383 TI - Moving On: Transition Readiness in Adolescents and Young Adults With IBD. AB - Background: Inflammatory bowel diseases (IBD) often begins early in life. Adolescents and young adults (AYA) with IBD have to acquire behaviors that support self-care, effective healthcare decision-making, and self-advocacy to successfully transition from pediatric to adult health care. Despite the importance of this critical time period, limited empirical study of factors associated with transition readiness in AYA exists. This study aimed to describe transition readiness in a sample of AYA with IBD and identify associated modifiable and nonmodifiable factors. Methods: Seventy-five AYA (ages 16-20) and their parents participated. AYA and parents reported on demographics, patient provider transition-related communication, and transition readiness. AYA self reported on disease self-efficacy. Disease information was abstracted from the medical record. Results: Deficits in AYA responsibility were found in knowledge of insurance coverage, scheduling appointments, and ordering medication refills. Older AYA age, higher AYA disease-management self-efficacy, and increased patient provider transition communication were each associated with higher overall transition readiness and AYA responsibility scores. Regression analyses revealed that older AYA age and increased patient-provider transition-related communication were the most salient predictors of AYA responsibility for disease management and overall transition readiness across parent and AYA reports. Conclusions: AYA with IBD show deficits in responsibility for their disease management that have the potential to affect their self-management skills. Findings suggest provider communication is particularly important in promoting transition readiness. Additionally, it may be beneficial to wait to transition patients until they are older to allow them more time to master skills necessary to responsibly manage their own healthcare. PMID- 29462384 TI - Free and Bioavailable 25-Hydroxyvitamin D Concentrations are Associated With Disease Activity in Pediatric Patients With Newly Diagnosed Treatment Naive Ulcerative Colitis. AB - Background: Vitamin D regulates intestinal epithelial and immune functions, and vitamin D receptor deficiency increases the severity of murine colitis. Bioavailable 25-hydroxyvitamin D (25(OH)D) is available to target tissues and may be a driver of immune function. The aim is to evaluate the relationship of bioavailable 25(OH)D to the clinical expression of treatment naive pediatric ulcerative colitis (UC). Methods: The PROTECT (Predicting Response to Standardized Pediatric Colitis Therapy) study enrolled children <=17 years newly diagnosed with UC. Free and total 25(OH)D were directly measured and 25(OH)D fractions were compared with disease activity measures. Results: Data were available on 388 subjects, mean age 12.7 years, 49% female, 84% with extensive/pancolitis. The median (IQR) total 25(OH)D concentration was 28.5 (23.9, 34.8) ng/mL, and 57% of subjects demonstrated insufficient vitamin D status (25(OH)D < 30 ng/mL). We found no evidence of association between total 25(OH)D and disease activity. Regression models adjusted for age, sex, race, and ethnicity demonstrated that an increase from 25th to 75th percentile for bioavailable and free 25(OH)D were associated with a mean (95th CI) decrease in the Pediatric Ulcerative Colitis Activity Index (PUCAI) of -8.7 (-13.7, -3.6) and -3.1 (-5.0, -1.2), respectively. No associations were detected between 25(OH)D fractions and fecal calprotectin or Mayo endoscopy score. Conclusions: Vitamin D insufficiency is highly prevalent in children with newly diagnosed UC. We found associations of free and bioavailable, but not total 25(OH)D, with PUCAI. Bioavailable vitamin D may contribute to UC pathophysiology and clinical activity. PMID- 29462385 TI - The Use of Vedolizumab in Preventing Postoperative Recurrence of Crohn's Disease. AB - Background: Clinical and endoscopic recurrence are common after surgery in Crohn's disease (CD). Vedolizumab has been increasingly used to treat CD, however, its effectiveness in preventing postoperative recurrence remains unknown. We aimed to investigate the use of vedolizumab in the postoperative setting and compare the risk of recurrence between patients receiving vedolizumab and anti-tumor necrosis factor (TNF)-alpha agents. Methods: Medical records of CD patients who underwent surgery between April 2014 and June 2016 were reviewed. We first analyzed how frequently vedolizumab is used to prevent postoperative recurrence and compared the patient characteristics with those being treated with other therapies. Furthermore, the rates of endoscopic remission, defined as a simple endoscopic score for CD of 0, at 6-12 months after surgery were compared between patients receiving vedolizumab and anti-TNF-alpha agents. Clinical, biological, and histologic outcomes such as Harvey-Bradshaw index, C-reactive protein, and histologic inflammation also were compared between the 2 groups. Risks of recurrence were assessed by univariate, multivariate, and propensity score-matched analyses. Results: Among 203 patients that underwent a CD related surgery, 22 patients received vedolizumab as postoperative treatment. There were 58, 38, and 16 patients who received anti-TNF-alpha agents, immunomodulators, and metronidazole, respectively, whereas 69 patients were monitored without any medication. Patients receiving vedolizumab were young and frequently had perianal disease. Patients postoperatively treated with vedolizumab or anti-TNF-alpha agents were mostly treated with the same agent pre- and postoperatively. Rate of endoscopic remission at 6-12 months in the vedolizumab group was 25%, which was significantly lower as compared to anti-TNF-alpha agent group (66%, P = 0.01). Vedolizumab use was the only factor that was associated with an increased risk of endoscopic recurrence on both univariate (odds ratio (OR) 5.58, 95% confidence interval (CI) 1.51-24.3, P = 0.005) and multivariate analysis (OR 5.77, 95%CI 1.71-19.4, P = 0.005). The results were supported by a propensity score-matched analysis demonstrating lower rates of endoscopic remission (25 vs 69%, P = 0.03) in patients treated with vedolizumab as compared to anti-TNF-alpha agents. Conclusion: In the present retrospective cohort study of real-world experience, vedolizumab was shown to be commonly used as postoperative treatment for CD especially in high risk patients. Multivariate and propensity score-matched analyses showed that postoperative endoscopic recurrence in CD was higher with vedolizumab than with anti-TNF-alpha agents, but further investigation including controlled trials is required before determining the utility of vedolizumab in preventing postoperative recurrence of CD.

PMID- 29462386 TI - Mice with Inflammatory Bowel Disease are Susceptible to Clostridium difficile Infection With Severe Disease Outcomes. AB - Background: Over the past several decades, there has been a significant increase in the incidence of Clostridium difficile infection (CDI) in patients suffering from inflammatory bowel disease (IBD). However, a wild-type animal model is not available to study these comorbid diseases. Methods: We evaluated the susceptibility to CDI of mice with dextran sulfate sodium salt (DSS)-induced colitis (IBD mice) with or without antibiotic exposure; we examined the histopathology and cytokine response in the concomitant diseases after the model was created. Results: No CDI occurs in healthy control mice, wherease the incidence of CDI in IBD mice is 40%; however, in IBD mice that received antibiotics, the incidence of CDI is 100% and the disease is accompanied by high levels of toxins in the mouse feces and sera. Compared to IBD and CDI alone, those IBD mice infected with C. difficile have more severe symptoms, toxemia, histopathological damage, and higher mortality. Moreover, several proinflammatory cytokines and chemokines are significantly elevated in the colon tissues from IBD mice infected with C. difficile. Conclusions: We, for the first time, demonstrate in an animal model that mice with dextran sulfate sodium induced-inflammatory bowel disease are significantly more susceptible to C. difficile infection, and that the bacterial infection led to more severe disease and death. These findings are consistent with clinical observations, thus, the animal model will permit us to study the pathogenesis of these concurrent diseases and to develop therapeutic strategies against the comorbidity of IBD and CDI. PMID- 29462388 TI - The Impact of NOD2 Variants on Fecal Microbiota in Crohn's Disease and Controls Without Gastrointestinal Disease. AB - Background/Aims: Current models of Crohn's disease (CD) describe an inappropriate immune response to gut microbiota in genetically susceptible individuals. NOD2 variants are strongly associated with development of CD, and NOD2 is part of the innate immune response to bacteria. This study aimed to identify differences in fecal microbiota in CD patients and non-IBD controls stratified by NOD2 genotype. Methods: Patients with CD and non-IBD controls of known NOD2 genotype were identified from patients in previous UK IBD genetics studies and the Cambridge bioresource (genotyped/phenotyped volunteers). Individuals with known CD associated NOD2 mutations were matched to those with wild-type genotype. We obtained fecal samples from patients in clinical remission with low fecal calprotectin (<250 ug/g) and controls without gastrointestinal disease. After extracting DNA, the V1-2 region of 16S rRNA genes were polymerase chain reaction (PCR)-amplified and sequenced. Analysis was undertaken using the mothur package. Volatile organic compounds (VOC) were also measured. Results: Ninety-one individuals were in the primary analysis (37 CD, 30 bioresource controls, and 24 household controls). Comparing CD with nonIBD controls, there were reductions in bacterial diversity, Ruminococcaceae, Rikenellaceae, and Christensenellaceae and an increase in Enterobacteriaceae. No significant differences could be identified in microbiota by NOD2 genotype, but fecal butanoic acid was higher in Crohn's patients carrying NOD2 mutations. Conclusions: In this well-controlled study of NOD2 genotype and fecal microbiota, we identified no significant genotype microbiota associations. This suggests that the changes associated with NOD2 genotype might only be seen at the mucosal level, or that environmental factors and prior inflammation are the predominant determinant of the observed dysbiosis in gut microbiota. PMID- 29462389 TI - Neoplasia and Precursor Lesions of the Female Genital Tract in IBD: Epidemiology, Role of Immunosuppressants, and Clinical Implications. AB - In this review the risk of breast, ovarian, and endometrial cancer and cervical and vulvovaginal (pre)malignant abnormalities in patients with inflammatory bowel disease (IBD) with or without immune suppressive treatment will be discussed. So far, this has not been studied thoroughly and large studies taking into account diverse potential confounding factors are lacking. IBD per se has not been associated with development of cervical cancer, yet patients with Crohn's disease who smoke, have a younger age at diagnosis or who use(d) thiopurines might be more at risk. Other immunosuppressive medication seems not to increase this risk, however, as evidence at this point is incomplete, physician awareness and prevention by lifestyle counseling, HPV vaccination and (intensified) screening are warranted. The risk for breast, endometrial, ovarian, and vulvovaginal cancer in IBD patients appears to be comparable to the background population, although for breast cancer this may even be decreasedin Crohn's disease specifically. Immunosuppressive medication in general does not seem to alter this risk. Earlier and more frequent screening for breast cancer than currently conducted in general nationwide screening programs is not recommended at this moment. Current literature suggests a much lower overall malignancy recurrence rate in IBD patients than has been observed previously. More importantly, immune suppressive medication does not appear to increase the recurrence risk. Robust epidemiologic data on female genital tract cancer are needed. PMID- 29462390 TI - Segmental Resection versus Total Proctocolectomy for Crohn's Colitis: What is the Best Operation in the Setting of Medically Refractory Disease or Dysplasia? AB - Crohn's disease (CD) may affect any part of the gastrointestinal tract. When isolated to the colon, and patients become medically refractory, there are several surgical options - segmental resection, subtotal colectomy with ileorectal anastomosis, or a total proctocolectomy and end ileostomy. Unfortunately, surgery does not cure CD, and, regardless of the extent of bowel removed, recurrence may be seen in the small bowel. This may lead to need for further immunosuppression or surgery. Therefore, when appropriate, a segmental colectomy or subtotal colectomy may prevent a permanent ostomy required with a total proctocolectomy. In the setting of dysplasia identified on colonoscopy, low quality evidence guides our treatment paradigms. Even though identification of dysplasia has greatly improved with chromoendoscopy, rates of synchronous or metachronous neoplasm remain high. Thus, a total proctocolectomy and end ileostomy, whereas a larger operation, may be best for the patient to remove all at risk tissue. Further research with prospective or randomized control trials is needed to improve our practice guidelines of both scenarios. PMID- 29462391 TI - Combination Immunosuppression in IBD. AB - Whether to use biologic treatment for inflammatory bowel disease as monotherapy or in combination with immunosuppressives has been a matter of debate in the last 2 decades. Combination therapy was not superior in any of the registration trials for Crohn's disease and ulcerative colitis for TNF antagonists, vedolizumab, or ustekinumab. It needs to be mentioned, though, that none of these trials were powered to detect such differences, and that many patients entered the trial after having failed conventional immunosuppressives.Postmarketing studies revealed that patients on background immunosuppression have a lower risk of immunogenicity (often resulting in infusion/injection reactions) than patients on monotherapy. In the SONIC and UC-SUCCESS trials, superiority of the combination azathioprine-infliximab was demonstrated in Crohn's disease and ulcerative colitis, respectively. This trial design has not been used with any other biologic for IBD, so far. Meanwhile, it has also become clear that combination treatment with TNF antagonists is associated with increased toxicity, mainly infections, but also malignancy such as lymphoproliferative disease. This toxicity could perhaps be reduced by using lower doses of immunosuppressives, a strategy that has been shown to be equally potent in reducing immunogenicity. Additionally, combination treatment could be used for a limited period of time (12 months or even shorter) since most immunogenicity develops in the beginning of the biologic treatment. Patients who develop anti-drug-antibodies later on can often be rescued by reintroduction of thiopurines or methotrexate.In summary, combination treatment is certainly beneficial with infliximab, at least in the first 12 months of treatment. With other TNF antagonists, vedolizumab, and ustekinumab, the available data do not offer clear guidance. In patients without increased risk of toxicity, and certainly in those with limited treatment options, it may be wise to offer combination treatment with all biologics for the time being and at least during the initiation phase.

PMID- 29462394 TI - Nondysplastic Ulcerative Colitis Has High Levels of the Homologous Recombination Repair Protein NUCKS1 and Low Levels of the DNA Damage Marker Gamma-H2AX. AB - Background: The colon and rectum are continuously exposed to oxidative stress that generates reactive oxygen species, which are a major cause of DNA double strand breaks (DSB). Furthermore, chronic inflammatory diseases such as ulcerative colitis (UC) are characterized by an excess of reactive nitrogen species that can also lead to DNA double-strand breakage and genomic instability. We investigated the expression of the nuclear casein kinase and cyclin-dependent kinase substrate 1 (NUCKS1) protein in UC and sporadic colorectal cancer (CRC) due to its involvement in both DNA double-strand break repair and inflammatory signaling. Methods: NUCKS1 expression and expression of the DNA double-strand break marker gamma-H2AX (gammaH2AX) were assessed in formalin-fixed, paraffin embedded UC and CRC patient biopsies using peroxidase immunohistochemistry. Expression levels for both proteins were evaluated together with previously published expression-level data for hTERT and TP53 proteins in the same material. Results: Nondysplastic UC lesions had 10-fold lower gammaH2AX expression and approximately 4-fold higher NUCKS1 expression compared with sporadic CRC, indicating minimal DNA DSB damage and heightened DNA DSB repair in these lesions, respectively. NUCKS1 expression in UC tended to decrease with increasing grades of dysplasia, whereas gammaH2AX, hTERT, and TP53 expression tended to increase with increasing grades of dysplasia. The highest gammaH2AX expression was seen in sporadic CRC, indicating considerable DNA DSB damage, whereas the highest NUCKS1 expression and hTERT expression were seen in nondysplastic UC. Conclusions: Overall, our data suggest that NUCKS1 may be involved in DNA DSB repair and/or inflammatory signaling in UC, but a more thorough investigation of both pathways in UC is warranted. PMID- 29462395 TI - Infliximab for Crohn's Disease: More Than 13 Years of Real-world Experience. AB - Background: The purpose of this study was to compare the long-term safety of infliximab and nonbiologic agents as Crohn's disease (CD) therapy. Methods: Patients with CD were prospectively evaluated in this large, observational registry. Results: Patients (n = 6273) participated in this observational registry from July 1999 through March 2012; 3440 (54.8%) received infliximab (20,971 patient-years), and 2833 (45.2%) received other treatments only (14,806 patient-years). Overall, 59,875 infliximab infusions were administered (80%, 5 mg/kg); 3006 (89.9%) patients received >=2 infusions. Adverse events (AEs), most commonly those related to CD (eg, abdominal pain, diarrhea), and serious AEs occurred at a higher rate among infliximab-treated patients. Mortality (0.57/100 patient-years, 0.67/100 patient-years) and malignancy rates (0.69/100 patient years, 0.71/100 patient-years) for infliximab-treated and other-treatments-only patients, respectively, were generally similar. Serious infection rates were higher for infliximab-treated (2.15/100 patient-years) than other-treatments-only patients (0.86/100 patient-years). Infliximab dose was not associated with mortality or serious infection. An increased risk of serious infection was observed with age (>52 years vs <=30 years) when examined in infliximab-treated patients. Nonserious cerebrovascular accidents (13 events, 0.06/100 patient years; 5 events, 0.03/100 patient-years) and pulmonary embolisms (11 events, 0.05/100 patient-years; 4 events 0.03/100 patient-years) also occurred at higher rates among infliximab-treated patients than other-treatments-only patients. Conclusions: Through more than 13 years of registry experience and an overall median duration of patient follow-up >6 years, mortality was similar between the infliximab-treated and other-treatments-only groups. These final cumulative results are representative of real-world experience among infliximab-treated patients with CD and are consistent with the known risks of disease activity and tumor necrosis factor antagonist therapy. PMID- 29462396 TI - Incorporation of Scribes Into the Inflammatory Bowel Disease Clinic Improves Quality of Care and Physician Productivity. AB - Background: Electronic health records (EHRs), despite their positive attributes, increase physician workload and decrease efficiency. The aim of this study was to evaluate the impact of scribes in the Inflammatory Bowel Disease Clinic on improvement of the physician-patient relationship, physician productivity, clinical efficiency, and achievement of some Physician Quality Reporting System (PQRS) metrics. Methods: We analyzed of pre- and postscribe data between fiscal years 2015 (FY15) and 2016 (FY16) using data from patients at the Inflammatory Bowel Clinic at the University of Florida. The main outcomes were patient satisfaction scores (PSS), qualitative physician interview, clinic appointment lengths, work relative value units (wRVUs), level of coding, revenue, and PQRS data on bone density screening and vaccination. Results: PSS increased from 6.8/10 to 9.2/10 (P < 0.01), clinic appointment length decreased by 13.5 minutes (P < 0.05), and documentation stress decreased. Clinic visits increased by 76, leading to an increase in work RVUs by 332.55, total charges billed by $71,439, and total charges collected by $27,387 between the first quarters of FY15 and FY16. The extra revenue for the first quarter was 536% higher than the salary of the scribe for the same period ($4302.84). There was a 1.8-fold increase in referrals for bone density scans and 2.9-fold and 4.8-fold increases in vaccination rates for influenza and pneumonia, respectively. Conclusions: The use of scribes improved the physician-patient relationship, clinical efficiency, physician productivity, bone density screening, and vaccinations for flu and pneumonia. If adopted by health systems, it may lead to significant cost savings and improved clinical outcomes. PMID- 29462397 TI - Duodenal Crohn's Disease. AB - Symptomatic duodenal Crohn's disease (CD) is an uncommon disease presentation, especially in isolation. The most common duodenal disease phenotype is stricturing disease rather than inflammatory or perforating. Most patients are asymptomatic and are therefore diagnosed incidentally by cross-sectional imaging or endoscopy. Medical management includes proton pump inhibitor therapy and immunosuppressive therapy including corticosteroids, immunomodulatory therapy, and biologic therapy. Symptomatic strictures can often be treated medically or endoscopically, and do not always require surgery. Surgical options include resection with primary anastomosis, bypass with a gastrojejunostomy, and strictureplasty. Treatment recommendations are largely based on limited evidence from small series and expert opinion. Therefore, the optimal treatment algorithm remains largely subjective and undefined. PMID- 29462398 TI - Full Interchangeability in Regard to Immunogenicity Between the Infliximab Reference Biologic and Biosimilars CT-P13 and SB2 in Inflammatory Bowel Disease. AB - Background: Infliximab (IFX) biosimilars CT-P13 and SB2 have comparable efficacy, safety, and immunogenicity to the originator Remicade (RMC). However, concerns about cross-switching patients between the 3 brands were raised in the absence of cross reactivity data between them. We aimed to determine whether antibodies to infliximab (ATI) in inflammatory bowel disease (IBD) patients cross-react with RMC, CT-P13, and SB2. Methods: Based on previous ATI status, samples from 34 patients participating in the BIOSIM01 study (13 RMC, 9 CT-P13, and 12 switchers) were selected. Patients were treated with either RMC only, or CT-P13 only, or with RMC switched to CT-P13. Additionally, 28 IFX-naive patients were assayed as controls. In total, 180 samples were analyzed. ATI trough levels were measured in parallel with 3 different bridging Enzyme Linked Immunosorbent Assays constructed using the 3 drugs. Spearman's coefficient and percentages of agreement were used to study the correlation between each assay. Results: In total, 76 samples out of 152 IFX-treated patient samples were ATI-positive (30 RMC, 14 CT-P13, and 32 switchers). All resulted ATI-positive when either CT-P13 or SB2 bridging assays were used. The overall percentage of agreement was 100% when compared either with CT-P13 or SB2 assays. No significant differences were found among ATI levels and coefficients (Spearman's 0.98 to 1.0, P < 0.0001). Conclusions: ATI of RMC treated, CT-P13-treated or RMC to CT-P13 switched patients show full cross reactivity with CT-P13 and SB2. Findings suggest that immunodominant epitopes in the reference and CT-P13 drugs are equally present in SB2. Data support full interchangeability between biosimilars in regard to immunogenicity. PMID- 29462399 TI - Mendelian Disease Associations Reveal Novel Insights into Inflammatory Bowel Disease. AB - Background: Monogenic diseases have been shown to contribute to complex disease risk and may hold new insights into the underlying biological mechanism of Inflammatory Bowel Disease (IBD). Methods: We analyzed Mendelian disease associations with IBD using over 55 million patients from the Optum's deidentified electronic health records dataset database. Using the significant Mendelian diseases, we performed pathway enrichment analysis and constructed a model using gene expression datasets to differentiate Crohn's disease (CD), ulcerative colitis (UC), and healthy patient samples. Results: We found 50 Mendelian diseases were significantly associated with IBD, with 40 being significantly associated with both CD and UC. Our results for CD replicated those from previous studies. Pathways that were enriched consisted of mainly immune and metabolic processes with a focus on tolerance and oxidative stress. Our 3-way classifier for UC, CD, and healthy samples yielded an accuracy of 72%. Conclusions: Mendelian diseases that are significantly associated with IBD may reveal novel insights into the genetic architecture of IBD.

PMID- 29462403 TI - Transferable vancomycin resistance in clade B commensal-type Enterococcus faecium. AB - Objectives: Vancomycin-resistant Enterococcus faecium is a leading cause of MDR hospital infection. Two genetically definable populations of E. faecium have been identified: hospital-adapted MDR isolates (clade A) and vancomycin-susceptible commensal strains (clade B). VanN-type vancomycin resistance was identified in two isolates of E. faecium recovered from blood and faeces of an immunocompromised patient. To understand the genomic context in which VanN occurred in the hospitalized patient, the risk it posed for transmission in the hospital and its origins, it was of interest to determine where these strains placed within the E. faecium population structure. Methods: We obtained the genome sequence of the VanN isolates and performed comparative and functional genomics of the chromosome and plasmid content. Results: We show that, in these strains, VanN occurs in a genetic background that clusters with clade B E. faecium, which is highly unusual. We characterized the chromosome and the conjugative plasmid that carries VanN resistance in these strains, pUV24. This plasmid exhibits signatures of in-host selection on the vanN operon regulatory system, which are associated with a constitutive expression of vancomycin resistance. VanN resistance in clade B strains may go undetected by current methods. Conclusions: We report a case of vancomycin resistance in a commensal lineage of E. faecium responsible for an atypical bacteraemia in an immunocompromised patient. A reservoir of transferable glycopeptide resistance in the community could pose a concern for public health. PMID- 29462405 TI - Gut barrier function: Effects of (antibiotic) growth promoters on key barrier components and associations with growth performance. AB - The gut barrier, comprising the microbiota and their products, mucus layers, host derived antimicrobial compounds [e.g., host defense peptides (HDP), IgA], epithelium, and underlying immune tissues, performs the essential function of preventing the passage of harmful microorganisms and substances into the body, while enabling the acquisition of dietary nutrients. Antibiotic growth promoters (AGP) are widely accepted as the "gold standard" of performance-enhancing feed additives, which had become integral and valuable components of modern, efficient animal production, but are now being phased out in many parts of the world. This review, therefore, examines the reported effects of AGP on the key components of gut barrier function, particularly where corresponding (positive) growth performance data were provided to indicate that any changes were beneficial, and some important trends do emerge. Certain bacterial families (e.g., Lachnospiraceae), genera (e.g., Faecalibacterium, Propionibacterium, and Ruminococcus), or species (e.g., F. prausnitzii, B. fragilis, and some Lactobacillus spp.) have been reported to increase with AGP use, are associated with improved growth performance, and show benefit across species, which may be related to their production of short-chain fatty acids (SCFA). Various studies have investigated the effects of AGP on mucus-related parameters (e.g., goblet cell size, density, and mucin mRNA expression) but these do not always seem to correlate well with the actual physical characteristics of the mucus layer(s). Surprisingly, there are little data relating to HDP or IgA, even though they have recognized benefits. There are clear AGP benefits on epithelial structure and function (e.g., nutrient digestibility), and these may (currently) provide the most reliable indicators of the efficacy of growth promoters. Data investigating effects on gut immune parameters (e.g., cell populations, cytokines, and chemokines), with corresponding growth performance, are limited and require further detailed interrogation. This review highlights both important observations related to the effects of AGP on key gut barrier components, with associated growth performance, and areas that require further investigation, thus providing an informative basis for assessing the potential of AGP alternatives. PMID- 29462406 TI - Long-term non-institutionalized survival and rehospitalization after surgical aortic and mitral valve replacements in a large provincial cardiac surgery centre. AB - OBJECTIVES: Long-term quality of life following open surgical valve replacement is an increasingly important outcome to patients and their caregivers. This study examines non-institutionalized survival and rehospitalization within our surgical aortic valve replacement (AVR) and mitral valve replacement (MVR) populations. METHODS: A retrospective single-centre study of all consecutive open surgical valve replacements between 1995 and 2014 was undertaken. Clinical data were linked to provincial administrative data for 3219 patients who underwent AVR, MVR or double (aortic and mitral) valve replacement with or without concomitant coronary artery bypass grafting (CABG). Non-institutionalized survival and cumulative incidence of rehospitalization was examined up to 15 years. RESULTS: Follow-up was complete for 96.9% of the 2146 patients who underwent AVR +/- CABG (66.7% of the overall cohort), 878 who underwent MVR +/- CABG (27.3%) and 195 who underwent double (aortic and mitral) valve replacement +/- CABG (6.0%) with a median follow-up time of 5.6 years. Overall non-institutionalized survival was 35.4% at 15 years, and the cumulative incidence of rehospitalization was 34.4%, 63.2% and 87.0% at 1, 5 and 15 years, respectively, without significant differences between valve procedure cohorts. Both non-institutionalized survival and cumulative incidence of rehospitalization improved in more recent eras, despite increasing age and comorbidities. CONCLUSIONS: Non-institutionalized survival and rehospitalization data for up to 15 years suggest good functional outcomes long after surgical AVR and/or MVR. Continued improvements are seen in these metrics over the past 2 decades. This provides a unique insight into the quality of life after surgical valve replacement in the ageing demographics with valvular heart disease. PMID- 29462404 TI - vmPFC activation during a stressor predicts positive emotions during stress recovery. AB - Despite accruing evidence showing that positive emotions facilitate stress recovery, the neural basis for this effect remains unclear. To identify the underlying mechanism, we compared stress recovery for people reflecting on a stressor while in a positive emotional context with that for people in a neutral context. While blood-oxygen-level dependent data were being collected, participants (N = 43) performed a stressful anagram task, which was followed by a recovery period during which they reflected on the stressor while watching a positive or neutral video. Participants also reported positive and negative emotions throughout the task as well as retrospective thoughts about the task. Although there was no effect of experimental context on emotional recovery, we found that ventromedial prefrontal cortex (vmPFC) activation during the stressor predicted more positive emotions during recovery, which in turn predicted less negative emotions during recovery. In addition, the relationship between vmPFC activation and positive emotions during recovery was mediated by decentering-the meta-cognitive detachment of oneself from one's feelings. In sum, successful recovery from a stressor seems to be due to activation of positive emotion related regions during the stressor itself as well as to their downstream effects on certain cognitive forms of emotion regulation. PMID- 29462407 TI - Transitional changes in the incidence of osteonecrosis in systemic lupus erythematosus patients: focus on immunosuppressant agents and glucocorticoids. AB - Objective: The purpose of this study was to investigate transitional changes in the incidence of glucocorticoid-associated osteonecrosis in SLE patients, with a focus on immunosuppressive agent and glucocorticoid consumption. Methods: We retrospectively registered 185 SLE patients with 740 joints, who were newly diagnosed and hospitalized for initial high-dose glucocorticoid therapy from 1986 to 2015. Immunosuppressive agent, glucocorticoid dose, age, sex, organ lesion at hospitalization, complement (C3, C4, CH50) and anti-DNA antibody before initial glucocorticoid therapy, the frequency of use of anticoagulant and antilipidemic drugs, and incidence of osteonecrosis were documented. Results: Based on trends in immunosuppressive agent use, 116 patients treated from 1986 to 1999, before calcineurin inhibitors were introduced, comprised the past group, and 69 patients treated from 2000 to 2015 comprised the recent group. Patient characteristics (age, sex and organ lesion at hospitalization, complement, anti-DNA antibody, the frequency of use of anticoagulant and antilipidemic drugs) were similar between groups. Glucocorticoid doses were significantly lower in the recent group than in the past group (highest daily glucocorticoid dose, 45.7 vs 59.0 mg/day, respectively; dose per weight, 0.88 vs 1.16 mg/day/kg, respectively; and cumulative dose at 3 months, 3118 vs 3985 mg). The incidence of osteonecrosis was significantly lower in the recent group than in the past group (26.4 vs 41.0%, respectively), particularly in the knee (25.4 vs 46.6%, respectively). Conclusion: The incidence of glucocorticoid-associated osteonecrosis in SLE patients decreased in association with a decrease in glucocorticoid administration after introduction of immunosuppressant agents. PMID- 29462408 TI - Effects of in ovo administration of L-ascorbic acid on broiler hatchability and its influence on the effects of pre-placement holding time on broiler quality characteristics,. AB - The current study was conducted to determine the possible effects of the in ovo administration of different dosages of L-ascorbic acid (AA) to broiler hatching eggs on hatchability and its potential for reducing the adverse effects of delayed placement.A total of 702 broiler hatching eggs was hand-injected at 17 d of incubation (DOI) with 100 MUL of sterile saline (0.85%) alone or containing 0.5, 1.5, 4.5, or 13.5 mg AA. Hatchability was recorded every 5 h from 480 h to 505 hours. Results showed that AA injection did not affect embryo BW as percentage of set egg weight or yolk sac weight as percentage of embryo weight at 19.5 DOI. The hatching time of all embryos that received an AA in ovo injection was between 480 and 495 h of incubation, and significantly fewer embryos hatched before 480 h in comparison to non-injected controls. Hatchability (above 92% in all groups) was not significantly affected by injection treatment. However, fertile eggs injected with saline containing 4.5 mg AA had the highest hatchability. At 21 DOI, hatching BW as a percentage of set egg weight and yolk sac weight as a percentage of BW were numerically higher in AA injection groups. An in ovo injection of AA at a 13.5 mg/egg level resulted in a numerically higher BW as a percentage of set egg weight. The in ovo injection of AA did not reduce the adverse effects of a 48-hour posthatch pre-placement holding time on BW or on yolk sac absorption. Overall, in ovo injection of L-ascorbic acid (0.5 to 13.5 mg/egg) into fertile broiler hatching eggs at 17 DOI did not negatively affect hatchability or embryo development, and did not prevent the negative effects of a 48-hour posthatch holding time on BW and yolk sac absorption. The range of tolerance as well as the optimal dosage of in ovo-injected AA warrants future study. PMID- 29462409 TI - The Behavior of Metropolis-Coupled Markov Chains When Sampling Rugged Phylogenetic Distributions. AB - Bayesian phylogenetic inference relies on the use of Markov chain Monte Carlo (MCMC) to provide numerical approximations of high-dimensional integrals and estimate posterior probabilities. However, MCMC performs poorly when posteriors are very rugged (i.e., regions of high posterior density are separated by regions of low posterior density). One technique that has become popular for improving numerical estimates from MCMC when distributions are rugged is Metropolis coupling (MC$^3$). In MC$^3$, additional chains are employed to sample flattened transformations of the posterior and improve mixing. Here, we highlight several underappreciated behaviors of MC3. Notably, estimated posterior probabilities may be incorrect but appear to converge, when individual chains do not mix well, despite different chains sampling trees from all relevant areas in tree space. Counterintuitively, such behavior can be more difficult to diagnose with increased numbers of chains. We illustrate these surprising behaviors of MC$^3$ using a simple, non-phylogenetic example and phylogenetic examples involving both constrained and unconstrained analyses. To detect and mitigate the effects of these behaviors, we recommend increasing the number of independent analyses and varying the temperature of the hottest chain in current versions of Bayesian phylogenetic software. Convergence diagnostics based on the behavior of the hottest chain may also help detect these behaviors and could form a useful addition to future software releases. PMID- 29462411 TI - Radiofrequency Energy and Electrode Proximity Influences Stereoelectroencephalography-Guided Radiofrequency Thermocoagulation Lesion Size: An In Vitro Study with Clinical Correlation. AB - BACKGROUND: Radiofrequency thermocoagulation of epileptogenic foci via stereoelectroencephalography (SEEG) electrodes has been suggested as a treatment for medically intractable epilepsy, but reported outcomes have been suboptimal, possibly because lesions generated using conventional high-energy radiofrequency parameters are relatively small. OBJECTIVE: To describe a technique of delivering low energy across separate SEEG electrodes in order to create large confluent radiofrequency lesions. METHODS: The size and configuration of radiofrequency lesions using different radiofrequency intensity and interelectrode distance was assessed in egg whites. Magnetic resonance images (MRI) from 3 patients who had undergone radiofrequency lesion creation were evaluated to determine the contribution of lesion intensity and electrode separation on lesion size. Electroencephalography, MRI, and clinical data were assessed before and after lesion creation. RESULTS: Both in Vitro and in Vivo analysis revealed that less energy paradoxically produced larger lesions, with the largest possible lesions produced when radiofrequency power was applied for long duration at less than 3 W. Linear separation of electrodes also contributed to lesion size, with largest lesions produced when electrodes were separated by a linear distance of between 5 and 12 mm. Clinical lesions produced using these parameters were large and resulted in improvement in interictal and ictal activity. CONCLUSION: Radiofrequency lesions produced using low-energy delivery between SEEG electrodes in close proximity can produce a large lesion. These findings might have advantages for treatment of focal epilepsy.

AB - Study Objectives: Brain-derived neurotrophic factor (BDNF) expression and homeostatic regulation of rapid eye movement (REM) sleep are critical for neurogenesis and behavioral plasticity. Accumulating clinical and experimental evidence suggests that decreased BDNF expression is causally linked with the development of REM sleep-associated neuropsychiatric disorders. Therefore, we hypothesize that BDNF plays a role in sleep-wake (S-W) activity and homeostatic regulation of REM sleep. Methods: Male and female wild-type (WT; BDNF +/+) and heterozygous BDNF (KD; BDNF +/-) rats were chronically implanted with S-W recording electrodes to quantify baseline S-W activity and REM sleep homeostatic regulatory processes during the light phase. Results: Molecular analyses revealed that KD BDNF rats had a 50% decrease in BDNF protein levels. During baseline S-W activity, KD rats exhibited fewer REM sleep episodes that were shorter in duration and took longer to initiate. Also, the baseline S-W activity did not reveal any sex difference. During the 3-hour selective REM sleep deprivation, KD rats failed to exhibit a homeostatic drive for REM sleep and did not exhibit rebound REM sleep during the recovery S-W period. Conclusion: Interestingly, both genotypes did not reveal any sex difference in the quality and/or quantity of REM sleep. Collectively, these results, for the first time, unequivocally demonstrate that an intact BDNF system in both sexes is a critical modulator for baseline and homeostatic regulation of REM sleep. This study further suggests that heterozygous BDNF knockdown rats are a useful animal model for the study of the cellular and molecular mechanisms of sleep regulation and cognitive functions of sleep.

AB - A meta-analysis was conducted to investigate the effect of mono-component proteases on performance and apparent ileal amino acid digestibility (AIAAD, %) in monogastrics. A total of 67 experimental trials were included in the meta analysis from published and internal reports, contributing 467 lines of data. Poultry and swine data accounted for 81 and 19% of the dataset, respectively. Forty-four different proteases were included in the meta-analysis, accounting for commercial and non-commercial products. Mixed Model analysis was used to assess protease effect and the influence of inherent characteristics of the control on protease response. The mean performance response to protease was a reduction in feed conversion ratio (FCR) for poultry (1%, P < 0.05) and swine (4%, P > 0.05). The mean relative effect of protease on AIAAD over the control was 1.6 +/- 0.3%, ranging from 1.2% for Arg, Phe and Trp to 2.6% for Cys. For the majority of amino acids, inherent AIAAD of control diets influenced (P < 0.05) the magnitude of the protease response such that, as inherent digestibility increased, the effect of protease on amino acid digestibility decreased. The dataset was subsequently divided into 2 subgroups: diets with and without other enzymes, namely non-starch polysaccharide degrading enzymes (NSPase) and phytase. Addition of protease in diets containing no other enzymes significantly (P < 0.05) increased AIAAD for the majority of amino acids and tended (P < 0.10) to improve Met, Trp, Pro, Gly, and Tyr. However, when other enzymes were included in the experiment, the beneficial effect of protease on AIAAD was lost (P > 0.05). These findings suggest that when other enzymes are already included in the diet, addition of protease requires further justification for use in monogastric diets. PMID- 29462414 TI - Primary glioblastoma cells for precision medicine: a quantitative portrait of genomic (in)stability during the first 30 passages. AB - Background: Primary glioblastoma cell (GC) cultures have emerged as a key model in brain tumor research, with the potential to uncover patient-specific differences in therapy response. However, there is limited quantitative information about the stability of such cells during the initial 20-30 passages of culture. Methods: We interrogated 3 patient-derived GC cultures at dense time intervals during the first 30 passages of culture. Combining state-of-the-art signal processing methods with a mathematical model of growth, we estimated clonal composition, rates of change, affected pathways, and correlations between altered gene dosage and transcription. Results: We demonstrate that GC cultures undergo sequential clonal takeovers, observed through variable proportions of specific subchromosomal lesions, variations in aneuploid cell content, and variations in subpopulation cell cycling times. The GC cultures also show significant transcriptional drift in several metabolic and signaling pathways, including ribosomal synthesis, telomere packaging and signaling via the mammalian target of rapamycin, Wnt, and interferon pathways, to a high degree explained by changes in gene dosage. In addition to these adaptations, the cultured GCs showed signs of shifting transcriptional subtype. Compared with chromosomal aberrations and gene expression, DNA methylations remained comparatively stable during passaging, and may be favorable as a biomarker. Conclusion: Taken together, GC cultures undergo significant genomic and transcriptional changes that need to be considered in functional experiments and biomarker studies that involve primary glioblastoma cells. PMID- 29462413 TI - Dietary oregano (Origanum vulgare L.) aqueous extract improves oxidative stability and consumer acceptance of meat enriched with CLA and n-3 PUFA in broilers. AB - The effect of a dietary oregano aqueous extract on meat fatty acid profile, quality, and consumer acceptance in chickens fed a diet rich in polyunsaturated fatty acids (PUFA) was evaluated in 3 consecutive trials.For each trial, 171 day old Ross 308 chicks were randomly divided in replicates of 19 birds each and assigned to one of 3 experimental diets: 1) basal control diet, 2) basal diet supplemented with 0.2 g/kg of oregano aqueous extract, and 3) basal diet supplemented with 150 ppm of vitamin E (as positive control). To better analyze the antioxidant activity of both oregano and vitamin E, all the experimental diets were enriched with a fatty acid supplement consisting in a mixture of PUFA at the same dose (1.16 %) in both starter and finisher feeds. Oregano supplementation positively influenced (P < 0.05) broiler live performance. No differences were observed in physicochemical or proximal composition or in total fatty acid composition of breast meat. Dietary oregano influenced meat composition in terms of total phenolic content, antioxidant capacity, and thiobarbituric acid-reactive substances, improving meat resistance to oxidation, compared to both other groups. During consumer tests, meat from the 3 dietary groups obtained the same liking score in a blind session. Under informed condition, consumer perception was positively influenced by labeling for all the considered attributes. Furthermore, consumers showed a higher expectation for meat derived from chickens fed the oregano extract when compared to that deriving from the other 2 groups.Results obtained in the present study allow stating that using oregano aqueous extract in diets enriched with PUFA can represent a valid solution to increase live weight of chickens, improve resistance to oxidation of meat, and positively influence consumer perception of poultry meat.

AB - This study aimed to investigate the effect of phytase and a combination of phytase and xylanase on the prececal phosphorus digestibility (pcdP) of wheat based diets in turkeys. A low-P basal diet (BD) based on cornstarch and soybean meal, and 2 diets containing 43% of different wheat genotypes (genotype diets GD6 or GD7) were fed to turkeys from 20 to 27 d of age. Diets were fed either without enzyme supplementation or supplemented with phytase (500 FTU/kg) or a combination of phytase and xylanase (16,000 BXU/kg). At 27 d of age, digesta were sampled from the lower ileum of animals to determine pcdP and pc myo-inositol 1,2,3,4,5,6 hexakis (dihydrogen phosphate) (InsP6) disappearance, and to analyze the concentrations of lower inositol phosphate isomers. Similar pcdP was observed in non-supplemented BD and GD (~36%). Phytase alone increased the pcdP in all diets by 8 to 12%, but a beneficial effect of xylanase was found only for BD. Similar results were found for pc InsP6 disappearance, although xylanase addition compared to phytase alone decreased pc InsP6 disappearance in GD7 compared to phytase alone. Animals fed GD7 performed better than those fed GD6; however, these differences could not be linked to the pcdP. The pattern of lower inositol phosphates in digesta also changed with enzyme supplementation, resulting in lower proportions of InsP5 and higher proportions of InsP4. Phytase alone decreased Ins(1,2,3,4,6)P5 but increased D-Ins(1,2,3,4,5)P5 and D-Ins(1,2,5,6)P4 concentrations. An additional increase in D-Ins(1,2,3,4,5)P5 and D-Ins(1,2,5,6)P4 concentrations was achieved with xylanase, although for the former isomer, this was observed only with GD. These results indicate that enzyme supplementation alters the pc degradation of InsP6, and that combining both enzymes had a minor additional effect on the pcdP from wheat-based diets when compared to phytase alone. PMID- 29462420 TI - Evaluation of a coccidia vaccine using spray and gel applications. AB - Coccidiosis is an economically significant disease of poultry caused by species of Eimeria, a parasitic protozoan. Disease can result in poor feed conversion, reduced weight gain, and can lead to the development of necrotic enteritis. For prevention of coccidiosis, poultry are commonly vaccinated with a live, sporulated oocysts mass applied with a vaccination cabinet in the hatchery. Traditionally, coccidia vaccines have been applied by coarse spray in a water based diluent, however, new technology using gel diluents has entered the US market. Gel diluents can have variable viscosities and are "dropped" onto chicks with an applicator bar. It is thought that gel droplets remain intact on the birds for longer than water based droplets, allowing more time for preening and ingestion of oocysts. In this experiment, the efficacy of a commercial coccidia vaccine applied with a water based diluent, a more viscous gel diluent, and a less viscous gel diluent was compared. Fecal samples were collected at multiple time points post-vaccination to quantify vaccine oocyst shedding. Shedding in the first cycle (days 5 to 8 post-vaccination) was related to the number of oocysts received from each application method, where the groups receiving higher doses shed more oocysts. However, a decrease in shedding was seen for the more viscous gel group in the second cycle (days 12 to 15 post-vaccination). Chickens were challenged with Eimeria maxima oocysts and 7 days post-challenge body weight gains and gross and microscopic lesions were recorded to evaluate protection levels for the different vaccine applications. All vaccinated groups appeared to be protected based on body weight gain and lesion scoring. The results of this project indicate that all vaccine applications are effective at protecting against Eimeria maxima challenge when using a proper dose of vaccine that allows for repeated oocyst cycling in the litter post-vaccination. PMID- 29462421 TI - Suppression of the IgM Response by Aryl Hydrocarbon Receptor Activation in Human Primary B Cells Involves Impairment of Immunoglobulin Secretory Processes. AB - Aryl hydrocarbon receptor (AHR) activation by 2, 3, 7, 8-tetrachlorodibenzo-p dioxin (TCDD) is well established at suppressing humoral immunity. Previous studies in mouse B cells revealed that decreased IgM production was due to a significant suppression in the mRNA levels of the immunoglobulin M components (IgH, IgJ, and Igkappa chains) and subsequent decrease in IgM synthesis. In contrast, the current study shows that activation of AHR in human B cells also results in a significant suppression of the number of IgM-secreting cells, but this is not due to a decrease in the transcription or translation of IgH, IgJ, and Igkappa chains. Instead, the reduced humoral response is due to the impairment of IgM secretion. This is further evidenced by an accumulation of intracellular IgM in human B cells, which indicates that activation of AHR alters distinct regulatory pathways in human and mouse B cells leading to the suppressed primary IgM response. Collectively, these results demonstrate that although AHR activation mediates suppression of humoral immune responses across many different animal species, the mechanism of action is not necessarily conserved across species.

AB - Multidrug resistance protein 1 (MDR1), a phase III drug transporter that exports substrates out of cells, has been discovered in both cancerous and normal tissues. The over expression of MDR1 in cancer cells contributes to multiple drug resistance, whereas the MDR1 in normal tissues protects them from chemical induced toxicity. Currently, the role of MDR1 in the ovary has not been entirely understood. Our objective is to determine the function of MDR1 in protecting against chemotherapy-induced ovarian toxicity. Using both the in vivo transgenic mouse model and in vitro follicle culture model, we investigated the expression of MDR1 in the ovary, the effect of MDR1 deficiency on doxorubicin (DOX)-induced ovarian toxicity, and the ovarian steroid hormonal regulation of MDR1. Results showed that the MDR1 was expressed in the ovarian epithelial cells, stroma cells, theca cell layers, endothelial cells, and luteal cells. The lack of MDR1 did not affect female ovarian function and fertility; however, its deficiency significantly exacerbated the DOX-induced ovarian toxicity in both in vivo and in vitro models. The MDR1 showed significantly higher expression levels in the ovaries at estrus and metestrus stages than those at proestrus and diestrus stages. However, this dynamic expression pattern was not regulated by the ovarian steroid hormones of estrogen (E2) and progesterone (P4) but correlated to the number and status of corpus luteum. In conclusion, our study demonstrates that the lack of MDR1 promotes DOX-induced ovarian toxicity, suggesting the critical role of MDR1 in protecting female ovarian functions during chemotherapy. PMID- 29462424 TI - Seasonal Distribution and Container Preference Ratio of the Dengue Fever Vector (Aedes aegypti, Diptera: Culicidae) in Rawalpindi, Pakistan. AB - Aedes aegypti (L.) and Aedes albopictus (Skuse) are known vectors of dengue, chikungunya, and other pathogens; however, their ecology and role in virus transmission has not been well studied in Pakistan. Here, we report on an intensive survey of potential breeding sites of Ae. aegypti in Rawalpindi, Punjab Province, Pakistan. The study continued for 11 mo and was divided into three seasons: January to June (pre-monsoon), July to September (monsoon), and October November (post-monsoon). Larval mosquitoes were collected from all wet containers present in and around the houses. Altogether 5,570,418, 2,930,508, and 1,507,111 water-filled containers were examined during each season, of which 2,703, 8,843, and 3,439 were found positive for Ae. aegypti larvae or pupae, yielding Breteau indices of 0.46, 2.92, and 1.99%, respectively. Among 14 container types examined, the breeding preference ratio during all seasons was highest for roof top water tanks and room evaporative coolers, followed by discarded tires and urban trash. The study concluded that increased urbanization, insufficient water supply and inefficient removal of urban trash resulted in increased numbers of nonbiodegradable containers around human dwellings, thereby creating ideal breeding habitats for Ae. aegypti. Measures such as integrated vector management, minimization of the breeding potential of Ae. aegypti by water management, proper disposal of discarded tires and urban trash, and health education were recommended for control of Ae. aegypti. PMID- 29462425 TI - Chitosan-adjuvanted Mycoplasma gallisepticum bacterin via intraocular administration enhances Mycoplasma gallisepticum protection in commercial layers. AB - Mycoplasma gallisepticum (MG) causes respiratory signs and economic losses in the poultry industry. MG vaccination is one of the effective prevention and control measures that have been used around the world. Our previous study demonstrated that chitosan-adjuvanted MG bacterin could effectively reduce pathological lesions induced by MG and that chitosan could be used as an adjuvant in MG bacterin. The present study determining the efficacy of MG bacterins against the Thai MG strain was based on vaccine programs. Seven groups (25 layers/group) were received MG bacterins containing 0.5% chitosan or a commercial bacterin via intramuscular (IM) or intraocular (IO) route at 6 and 10 wk of age. Sham-negative and sham-positive controls were groups 1 and 2, respectively. Group 3: IM route of chitosan bacterin followed by IM route of chitosan bacterin; group 4: commercial bacterin via IM route followed by chitosan bacterin via IO route; group 5: commercial bacterin via IM route followed by commercial bacterin via IM route; group 6: chitosan bacterin via IM followed by chitosan bacterin via IO route; and group 7: chitosan bacterin via IO route followed by chitosan bacterin via IO route were determined. At 16 wk of age, all groups, excluding group 1, were challenged intratracheally with 0.1 mL containing Thai MG strain 107 colony forming unit. At 17, 18, and 20 wk of age, 5 birds in each group were bled for serological testing and swabbed at the choanal cleft for the quantitative real time PCR assay, the euthanized and necropsied. The results showed that birds vaccinated with a commercial intramuscular bacterin followed by an intraocularly chitosan adjuvant bacterin showed the best protection against the MG challenge. The study indicated that chitosan could be the effective mucosal adjuvant and increased the effectiveness of MG bacterin. PMID- 29462426 TI - Arabidopsis BRASSINOSTEROID INACTIVATOR2 is a typical BAHD acyltransferase involved in brassinosteroid homeostasis. AB - Brassinosteroids (BRs) are plant-specific steroidal hormones; BR homeostasis is crucial for various aspects of plant growth and development. However, to date, the BR inactivation process has not been thoroughly elucidated. In this study, we identified and characterized a novel BAHD family acyltransferase gene, BRASSINOSTEROID INACTIVATOR2 (BIA2), involved in BR inactivation. BIA2 overexpressing (OE-BIA2) plants displayed typical BR-deficient phenotypes, which were rescued by exogenous BR treatment. Real-time qRT-PCR and transcriptome analyses showed that expression levels of virtually all of the BR biosynthetic genes were increased, whereas the expression of many BR inactivation genes was reduced in OE-BIA2 plants. Root inhibition assays showed that the root growth of OE-BIA2 plants was inhibited. We obtained plants with an intermediate phenotype by crossing the OE-BIA2 plants with BRASSINOSTEROID-INSENSITIVE1 (BRI1) overexpressing plants. The null BIA2 mutants had longer hypocotyls in the dark. BIA2 was predominantly expressed in roots, and its expression was induced by 24 epibrassinolide or dark treatment, but it exhibited a differential expression pattern compared with its homologue, BIA1. Furthermore, genetic transformation with point-mutant and deleted-BIA2 constructs confirmed that the HXXXD motif is essential for the function of BIA2. Taken together, these findings indicate that BIA2 is a typical BAHD acyltransferase that is involved in BR homeostasis and may inactivate bioactive BRs by esterification, particularly in roots and hypocotyls under dark conditions. PMID- 29462427 TI - Effects of terrestrial runoff on the coral communities in Santiago Bay, Colima, Mexican Pacific Coast. AB - Coral reef ecosystems are under stress of different origins, from factors including sedimentation, fragmentation, overfishing, and tourism, depending on their geographical location, depth, and proximity to recreation areas. In this study of Juluapan Lagoon, we examined the relationship between various water quality attributes and the status indicators of the coral community at La Boquita reef. During 2011 (12 months of sampling), six monitoring stations in the Juluapan lagoon were established in order to observe the gradient of the distribution of the physicochemical parameters: three stations on the upper part, or BI, (S4 to S6) and three more in the lower part, or BII, (S1 to S3). A control station (CS) was located in the coral reef close to the lagoon channel, and where dissolved inorganic nutrients and cellular carbon content were determined. Additionally, we considered the monitoring of three of the eight largest coral structures/headlands of this community: the first was the station closest to the channel communicating with Juluapan lagoon (C1), the second was in the intermediate region with respect to that lagoon (C2), and the third was farthest from the channel (C3). Three line intercept transects (LIT) 30 m in length and perpendicular to the coast provenance were established in each station, and the parameters indicative of the status of corals were evaluated in an area of 60 m2 on each transect (180 m2 by the station). Turbidity, evidence of fishing, signs of settling, algal coverage, abundance of fish, rate of sediment, and coral health records (as for CoralWach chart) were determined in situ and from digital photographs and videos. Considering various community status indicators used in the reef area, we could recognize a state of general deterioration, which was reflected in the loss of 17 % of coral coverage. The main anthropogenic disturbances in adjacent areas to La Boquita reef included wastewater discharges into the lagoon, tourist developments in the coastal zone, deforestation and erosion resulting from inappropriate development, and the runoff of nutrients from agricultural lands nearby the lagoon. All these significantly contributed to the nutrient-enriched waters of the lagoon, especially in summer, with negative effects on the coral community. Continued exposure to these factors, coupled with the lack of control over other anthropogenic components, has promoted the maintenance of a chronic stress state in the studied coral community. Our findings highlight the need for the development of appropriate coastal management and conservation policies for the coral reefs of the Mexican Pacific Coast. PMID- 29462428 TI - Gene mutation and micronucleus assays in gpt delta mice treated with 2,2',4,4' tetrabromodiphenyl ether. AB - Flame retardant polybrominated diphenyl ethers (PBDEs) are a class of persistent organic pollutants (POPs). 2,2',4,4'-Tetrabromodiphenyl ether (BDE-47) is a representative PBDE congener with widespread distribution and relatively high toxicity potential. Although it has been reported that BDE-47 can cause DNA damage in various in vitro systems, few studies have provided in vivo genotoxicity information. The aim of the present study was to investigate the genotoxicity of BDE-47 in mice. Male gpt delta mice were administered BDE-47 by gavage at 0, 0.0015, 1.5, 10 and 30 mg/kg/day, and 6 days per week for six consecutive weeks. Before the first treatment, and at 2.5 and 5 weeks after the first treatment, peripheral blood was collected from tails and the micronucleus assay and the Pig-a gene mutation assay were performed. After the last treatment, the mutant frequencies of the gpt gene in the liver and the germ cells from seminiferous tubules were determined. All these assays failed to produce positive results, suggesting that BDE-47 was neither clastogenic nor mutagenic in both target and non-target tissues in gpt delta mice. PMID- 29462429 TI - A glycomics approach to discover novel renal biomarkers in birds by administration of cisplatin and diclofenac to chickens. AB - Avian species have a unique renal structure and abundant blood flow into the kidneys. Although many birds die due to nephrotoxicity caused by chemicals, there are no early biomarkers for renal lesions. Uric acid level in blood, which is generally used as a renal biomarker, is altered when the kidney function is damaged by over 70%. Therefore, early biomarkers for kidney injury in birds are needed. In humans, glycomics has been at the forefront of biological and medical sciences, and glycans are used as biomarkers of diseases, such as carcinoma. In this study, a glycomics approach was used to screen for renal biomarkers in chicken. First, a chicken model of kidney damage was generated by injection of diclofenac or cisplatin, which cause acute interstitial nephritis (AIN) and acute tubular necrosis (ATN), respectively. The nephrotoxicity levels were determined by a blood chemical test and histopathological analysis. The plasma N-glycans were then analyzed to discover renal biomarkers in birds. Levels of 14 glycans increased between pre- and post administration in kidney-damaged chickens in the diclofenac group, and some of these glycans had the same presumptive composition as those in human renal carcinoma patients. Glycan levels did not change remarkably in the cisplatin group. It is possible that there are changes in glycan expression due to AIN, but they do not reflect ATN. Although further research is needed in other species of birds, glycans are potentially useful biomarkers for AIN in avian species. PMID- 29462430 TI - Education and management of antimicrobials amongst nurses in Africa-a situation analysis: an Infection Control Africa Network (ICAN)/BSAC online survey. AB - Objectives: To assess the current involvement of nurses in the use and management of antimicrobials and their training in antimicrobial stewardship (AMS) across Africa. Methods: After a pilot study, an online questionnaire (SurveyMonkey) in both French and English was circulated via the Infection Control Africa Network (ICAN) mailing list to both members and non-members in Africa. The study was conducted from 26 May to 19 August 2016. Data were summarized in proportions and bar charts; proportions were compared using the chi2 test. A multivariate logistic regression model was built to identify independent factors associated with the practice of AMS. Results: While 96% of the 173 respondents were aware of the term 'AMS', 88.5% (146/165) undertook AMS tasks as part of their job; 91.9% (158/172) wanted to be more involved in AMS but 44.9% (71/158) reported there were barriers in doing so. AMS training was delivered to 36.7% (62/169) and 53.6% (90/168), respectively, during their undergraduate and postgraduate education. AMS training for healthcare workers in their institutions was reported by 50.3% (86/171), including training aimed at doctors (56.9%), pharmacists (76.7%), microbiologists (31.4%) and nurses (95.3%). However, 95.4% (164/172) of respondents asked for further education on AMS and the majority preferred AMS training to be part of the infection prevention curriculum (IPC) education. Three quarters of institutions had an AMS initiative, but only ~41% reported having seen a national AMS guideline. Conclusions: For Africa, we recommend AMS education at undergraduate level, AMS policies at institution and national levels and incorporating AMS training into the IPC for nurses. PMID- 29462431 TI - CONCENTRATION OF RADON IN DWELLINGS OF HEMAVATHI RIVER BASIN, KARNATAKA, INDIA. AB - Indoor radon, thoron and their progeny levels were measured in various types of dwellings during 2016-17 in Hemavathi river basin, Karnataka by using solid state nuclear track detector based pin-hole dosemeters; dwellings of various types were chosen for the measurement. The dosemeters containing the detector (LR-115, Type II Film) was used for this purpose. The concentration of indoor radon in the study area varied from 30.72 to 196.08 Bq m-3 with a median of 83.13 Bq m-3 and thoron concentration varied from 15.56 to 227.78 Bq m-3. Higher concentrations of radon and its progeny were observed in granite flooring and cement roofing dwellings compared to other types of dwellings. The reason for higher concentration of indoor radon and its progeny is due to activity of radium present in granite and provision of less ventilation in dwellings. The equilibrium equivalent radon, thoron concentrations and annual effective dose are discussed.

AB - BACKGROUND: Congenital spinal stenosis (CSS) of the cervical spine is a risk factor for acute spinal cord injury and development of degenerative cervical myelopathy (DCM). OBJECTIVE: To develop magnetic resonance imaging (MRI)-based criteria to diagnose preexisting CSS and evaluate differences between patients with and without CSS. METHODS: A secondary analysis of international prospectively collected data between 2005 and 2011 was conducted. We examined the data of 349 surgical DCM patients and 27 controls. Spinal canal and cord anteroposterior diameters were measured at noncompressed sites to calculate spinal cord occupation ratio (SCOR). Torg-Pavlov ratios and spinal canal diameters from radiographs were correlated with SCOR. Clinical and MRI factors were compared between patients with and without CSS. Surgical outcomes were also assessed. RESULTS: Calculation of SCOR was feasible in 311/349 patients. Twenty six patients with CSS were identified (8.4%). Patients with CSS were younger than patients without CSS (P = .03) and had worse baseline severity as measured by the modified Japanese Orthopedic Association score (P = .04), Nurick scale (P = .05), and Neck Disability Index (P < .01). CSS patients more commonly had T2 cord hyperintensity changes (P = .09, ns) and worse SF-36 Physical Component scores (P = .06, ns). SCOR correlated better with Torg-Pavlov ratio and spinal canal diameter at C3 than C5. Patients with SCOR >= 65% were also younger but did not differ in baseline severity. CONCLUSION: SCOR >= 70% is an effective criterion to diagnose CSS. CSS patients develop myelopathy at a younger age and have greater impairment and disability than other patients with DCM. Despite this, CSS patients have comparable duration of symptoms, MRI presentations, and surgical outcomes to DCM patients without CSS. PMID- 29462434 TI - Effects of in ovo injection of different doses of coccidiosis vaccine and turn out times on broiler performance,. AB - Inovocox EM1 vaccine (EM1) is hatchery-applied via in ovo injection for the control of coccidiosis in broiler chickens. Effects of 3 in ovo injection treatments (INT) and 2 turn-out times (TOT) on the hatching chick quality variables and 35 d posthatch performance of Ross * Ross 708 broilers were investigated. In a single-stage incubator, 1,440 hatching eggs were randomly distributed among 3 INT groups on each of 8 tray levels. At 19 d of incubation (doi), embryonated eggs were subjected to one of the following INT by in ovo injection: noninjected control; 1 * dose of EM1; 10 * dose of EM1. On 21 doi, hatchability of injected eggs (HI), hatching body weight (HBW), and hatching chick quality variables were determined. Additionally, for the grow-out phase, birds belonging to each INT were randomly subjected to a 7 or 10 d TOT. Twenty chicks were initially placed in each of 48 floor pens (6 INT * TOT combination groups * 8 replications) for growth performance evaluation from 0 to 35 d posthatch. The main effect of INT on hatching chick quality variables, as well as the main and interactive effects of INT and TOT on various grow-out performance variables were determined. Although there was no significant INT effect on HI or HBW, significant INT effects on chick total BW, yolk-free BW, and yolk sac weight were observed. There were significant INT effects on BWG and FCR in the 21- to 28 d posthatch interval, as well as on BWG and FCR in the 0- to 35-d posthatch interval. There was no main effect of TOT or interactive effect of INT and TOT on BW and other performance variables from 0 to 35 d posthatch. There was a significant main effect of INT on relative intestine weight at 28 d posthatch. In conclusion, the injection of EM1 vaccine at a 10 * dose may affect hatching chick quality variables and growth performance up to 35 d posthatch.

PMID- 29462444 TI - Business travel-associated illness: a GeoSentinel analysis. AB - Background: Analysis of a large cohort of business travelers will help clinicians focus on frequent and serious illnesses. We aimed to describe travel-related health problems in business travelers. Methods: GeoSentinel Surveillance Network consists of 64 travel and tropical medicine clinics in 29 countries; descriptive analysis was performed on ill business travelers, defined as persons traveling for work, evaluated after international travel 1 January 1997 through 31 December 2014. Results: Among 12 203 business travelers seen 1997-2014 (14 045 eligible diagnoses), the majority (97%) were adults aged 20-64 years; most (74%) reported from Western Europe or North America; two-thirds were male. Most (86%) were outpatients. Fewer than half (45%) reported a pre-travel healthcare encounter. Frequent regions of exposure were sub-Saharan Africa (37%), Southeast Asia (15%) and South Central Asia (14%). The most frequent diagnoses were malaria (9%), acute unspecified diarrhea (8%), viral syndrome (6%), acute bacterial diarrhea (5%) and chronic diarrhea (4%). Species was reported for 973 (90%) of 1079 patients with malaria, predominantly Plasmodium falciparum acquired in sub Saharan Africa. Of 584 (54%) with malaria chemoprophylaxis information, 92% took none or incomplete courses. Thirteen deaths were reported, over half of which were due to malaria; others succumbed to pneumonia, typhoid fever, rabies, melioidosis and pyogenic abscess. Conclusions: Diarrheal illness was a major cause of morbidity. Malaria contributed substantial morbidity and mortality, particularly among business travelers to sub-Saharan Africa. Underuse or non-use of chemoprophylaxis contributed to malaria cases. Deaths in business travelers could be reduced by improving adherence to malaria chemoprophylaxis and targeted vaccination for vaccine-preventable diseases. Pre-travel advice is indicated for business travelers and is currently under-utilized and needs improvement. PMID- 29462447 TI - Radiographic and Neurological Outcome After Surgical Treatment of Traumatic Fractures of the Ankylotic Thoracic Spine: A Retrospective Case Series. AB - BACKGROUND: Spontaneous thoracic ankylosis is a progressive degenerative process that predisposes patients to potentially highly unstable traumatic injuries. Acute hyperextension fractures result in dynamic instability putting the spinal cord at risk. OBJECTIVE: To describe preoperative radiographic characteristics of fractures of the ankylotic thoracic spine and relate findings to early postoperative radiographic and clinical outcomes. METHODS: A single center, retrospective review was performed of 28 surgically treated patients with fractures of the ankylotic thoracic spine. Radiographic assessment included preoperative fracture angulation (FA) and fracture displacement (FD), and postoperative change in sagittal alignment. Early clinical outcomes included preoperative and postoperative American Spinal Injury Association (ASIA) grade and perioperative complications. RESULTS: Seven patients (25%) presented with poor neurological grade (ASIA A-C) compared to 21 (75%) with good grade (ASIA D, E). At presentation, poor grade patients had a mean FA of 16.4 degrees (range 0 degrees -34.5 degrees ), and FD of 7.76 mm (range 0.8-9.2). Good grade patients had a mean FA of 18.2 degrees (range 0 degrees -43.3 degrees ), and FD of 4.77 mm (range 0-25.1). There was no statistically significant difference in FA or FD between groups (P = .70 and .20 respectively). All underwent posterior pedicle screw fixation for stabilization. Fifty per cent of patients presenting with ASIA C or D spinal cord injury improved 1 or more ASIA grades. There were no perioperative complications. Early postoperative sagittal alignment was maintained with a mean change of -2.6 degrees . CONCLUSION: Presenting fracture alignment does not significantly correlate with pre- or postoperative neurological status. Early posterior stabilization preserved neurological function, with neurological recovery occurring in a portion of individuals. PMID- 29462446 TI - Accuracy and Efficacy for Robotic Assistance in Implanting Responsive Neurostimulation Device Electrodes in Bilateral Mesial Temporal Lobe Epilepsy. AB - BACKGROUND: Responsive neurostimulation (RNS) is a relatively new treatment option that has been shown to be effective for patients with medically refractory focal epilepsy when resection is not possible, especially in bilateral mesial temporal onset. Robotic devices are becoming increasingly popular for use in stereotactic procedures such as stereoelectroencephalography, but have yet to be used when implanting RNS devices. OBJECTIVE: To show that these 2 forms of advanced technology were compatible and could be used effectively in patient care. METHODS: We implanted RNS devices in 3 patients with bilateral mesial temporal lobe epilepsy. Each patient was placed in the prone position, and electrode trajectories were planned via the robotic navigation system via a transoccipital approach. One lead was placed along each amygdalohippocampal complex. A small craniectomy was then created in the parietal region for RNS generator implantation. Actual and expected target locations and distance were calculated for each depth. There were no complications in this group. RESULTS: RNS devices with bilateral leads were successfully implanted in all 3 patients, with bilateral mesial temporal lobe onset. Follow-up ranged from 3 to 6 mo, and there were no complications in this group. The median distance between the estimate and actual targets was 2.18 (range = 1.11-3.27) mm. CONCLUSION: We show that implanting RNS devices with robotic assistance is feasible with excellent precision and accuracy. The advantages of using robotic assistance include higher flexibility, accuracy, precision, and consistency. PMID- 29462448 TI - Spinal Cord Suspension Using Dentate Ligament Hitch Stitches: A Novel Technique for the Repair of Ventral Spinal Cord Herniation. AB - BACKGROUND: Idiopathic spinal cord herniation is usually repaired by releasing the spinal cord and inserting a dural patch to close the herniated segment of dura. However, reherniation is a potential limitation of this standard technique. OBJECTIVE: To describe early results of a novel technique that utilizes the dentate ligament to hitch the spinal cord and prevent reherniation. METHODS: Two patients underwent dural hernia repair and the dentate hitch technique was performed. RESULTS: Restored lower limb power and mobility, and satisfactory reduction of spinal cord herniation on magnetic resonance imaging in 2 patients at 6- and 24-mo follow-ups, respectively. CONCLUSION: The dentate hitch technique can achieve repair of spinal cord herniation, with satisfactory postoperative results and minimizes the risk of reherniation. PMID- 29462449 TI - Endoscopic Transorbital Superior Eyelid Approach for the Management of Selected Spheno-orbital Meningiomas: Preliminary Experience. AB - BACKGROUND: Feasibility and safety of spheno-orbital meningioma resection by means of endoscopic-assisted transorbital route. OBJECTIVE: To evaluate the feasibility and outcomes of the transorbital endoscopic management of selected spheno-orbital meningiomas. As secondary aims, symptom improvement and tumor volume removed were evaluated. METHODS: Retrospective chart evaluation of patients with spheno-orbital meningiomas treated by means of endoscopic transorbital superior eyelid approach in 3 referral centers over the last 4 yr. RESULTS: Fourteen cases were included in this study. In 4 patients, the transorbital endoscopic approach was combined with an endonasal route. Mean age was 51 and male-to-female ratio was 1:6. In 8 patients (57.1%), an intraorbital involvement was observed, 3 of them (21.4%) showed significant intraconal disease. No patient presented significant cavernous sinus infiltration. Main presenting symptoms were proptosis, diplopia, and visual impairment in 14, 6, and 6 patients, respectively. Mean proptosis improvement was 2 mm (standard deviation 2.3). We observed no major postoperative complications. CONCLUSION: Our preliminary clinical experience seems to demonstrate that selected spheno-orbital meningiomas can be safely managed by means of an endoscopic transorbital route through a superior eyelid approach. Patients with orbital or cavernous sinus infiltration are at highest risk of persistence. PMID- 29462450 TI - False-Positive and False-Negative Results of Motor Evoked Potential Monitoring During Surgery for Intramedullary Spinal Cord Tumors. AB - BACKGROUND: Motor evoked potential (MEP) recording is used as a method to monitor integrity of the motor system during surgery for intramedullary tumors (IMTs). Reliable sensitivity of the monitoring in predicting functional deterioration has been reported. However, we observed false positives and false negatives in our experience of 250 surgeries of IMTs. OBJECTIVE: To delineate specificity and sensitivity of MEP monitoring and to elucidate its limitations and usefulness. METHODS: From 2008 to 2011, 58 patients underwent 62 surgeries for IMTs. MEP monitoring was performed in 59 operations using transcranial electrical stimulation. Correlation with changes in muscle strength and locomotion was analyzed. A group undergoing clipping for unruptured aneurysms was compared for elicitation of MEP. RESULTS: Of 212 muscles monitored in the 59 operations, MEP was recorded in 150 (71%). Positive MEP warnings, defined as amplitude decrease below 20% of the initial level, occurred in 37 muscles, but 22 of these (59%) did not have postoperative weakness (false positive). Positive predictive value was limited to 0.41. Of 113 muscles with no MEP warnings, 8 muscles developed postoperative weakness (false negative, 7%). Negative predictive value was 0.93. MEP responses were not elicited in 58 muscles (27%). By contrast, during clipping for unruptured aneurysms, MEP was recorded in 216 of 222 muscles (96%). CONCLUSION: MEP monitoring has a limitation in predicting postoperative weakness in surgery for IMTs. False-positive and false-negative indices were abundant, with sensitivity and specificity of 0.65 and 0.83 in predicting postoperative weakness. PMID- 29462451 TI - Transsylvian Transuncal Approach for an Anterior Midbrain Cavernous Malformation Resection: A Case Report. AB - BACKGROUND AND IMPORTANCE: Cavernous malformations (CMs) are vascular abnormalities with a hemorrhage risk of 0.2% to 5% per year, according to their location. Brainstem CMs seem to have a greater hemorrhagic risk and represent a neurosurgical challenge. We report here the first transsylvian transuncal (TS-TU) approach for an anteromedial mesencephalic CM resection. CLINICAL PRESENTATION: A 29-yr-old female suddenly presented a left hemiparesis and central facial paresis with a diplopia in the upward gaze. A cerebral imagery revealed an 18-mm right cerebral peduncle CM with signs of acute hemorrhage. Two months later, she rebleed while pregnant. The pregnancy was interrupted. Five months later, a 3.0 Tesla magnetic resonance imaging (MRI) with diffusion tensor imaging sequences was realized for preoperative planning followed by a gross total resection of the CM through a TS-TU approach to avoid the perforating arteries of the anterior perforated substance. The patient presented postoperatively again a left hemiparesis and central facial paresis with a right oculomotor nerve paresis. On the tenth postsurgical day, she developed a Holmes' tremor of the left upper limb, for which a Levodopa treatment was initiated. Three months postoperative, MRI showed a gross total resection of the mesencephalic CM without complications. A complete clinical recovery was observed 1 yr later. CONCLUSION: We describe here the first performance of a TS-TU approach for an anterior mesencephalic CM resection. This surgical approach allowed direct access to the CM, avoiding the vascularization of the anterior perforated substance.

AB - BACKGROUND: Schizophrenia is associated with increased physical morbidity and early mortality, suggesting that the aging process may be accelerated in schizophrenia. However, the biological underpinnings of these alterations in aging in schizophrenia are unclear. METHOD: We conducted a detailed search of peer-reviewed empirical studies to evaluate evidence for accelerated biological aging in schizophrenia based on systemic, age-related biomarkers. We included studies that investigated differences between persons with schizophrenia and healthy comparison subjects in levels of biomarkers known to be associated with aging and examined the relationship of these biomarkers to age in the 2 groups. RESULTS: Forty-two articles that met our selection criteria were reviewed. Nearly 75% reported abnormal biomarker levels among individuals with schizophrenia, including indices of inflammation, cytotoxicity, oxidative stress, metabolic health, gene expression, and receptor/synaptic function, with medium to large effect sizes reported in many studies. Twenty-nine percent of the studies observed differential age-related decline in schizophrenia. Markers of receptor/synaptic function and gene expression were most frequently differentially related to age in schizophrenia. Schizophrenia patients with greater disease severity and longer illness duration exhibited higher levels of inflammatory and oxidative stress biomarkers and shorter telomere length. CONCLUSIONS: Most studies show biomarker abnormalities in schizophrenia, and there is some suggestion for accelerated aging. Although definitive interpretation is limited by cross-sectional design of the published reports, findings in the area of gene expression and synaptic function are promising and pave the way for future longitudinal studies needed to fully test this hypothesis. PMID- 29462456 TI - N-acetylcysteine in a Double-Blind Randomized Placebo-Controlled Trial: Toward Biomarker-Guided Treatment in Early Psychosis. AB - Biomarker-guided treatments are needed in psychiatry, and previous data suggest oxidative stress may be a target in schizophrenia. A previous add-on trial with the antioxidant N-acetylcysteine (NAC) led to negative symptom reductions in chronic patients. We aim to study NAC's impact on symptoms and neurocognition in early psychosis (EP) and to explore whether glutathione (GSH)/redox markers could represent valid biomarkers to guide treatment. In a double-blind, randomized, placebo-controlled trial in 63 EP patients, we assessed the effect of NAC supplementation (2700 mg/day, 6 months) on PANSS, neurocognition, and redox markers (brain GSH [GSHmPFC], blood cells GSH levels [GSHBC], GSH peroxidase activity [GPxBC]). No changes in negative or positive symptoms or functional outcome were observed with NAC, but significant improvements were found in favor of NAC on neurocognition (processing speed). NAC also led to increases of GSHmPFC by 23% (P = .005) and GSHBC by 19% (P = .05). In patients with high-baseline GPxBC compared to low-baseline GPxBC, subgroup explorations revealed a link between changes of positive symptoms and changes of redox status with NAC. In conclusion, NAC supplementation in a limited sample of EP patients did not improve negative symptoms, which were at modest baseline levels. However, NAC led to some neurocognitive improvements and an increase in brain GSH levels, indicating good target engagement. Blood GPx activity, a redox peripheral index associated with brain GSH levels, could help identify a subgroup of patients who improve their positive symptoms with NAC. Thus, future trials with antioxidants in EP should consider biomarker-guided treatment. PMID- 29462458 TI - m-AAA Complexes Are Not Crucial for the Survival of Arabidopsis Under Optimal Growth Conditions Despite Their Importance for Mitochondrial Translation. AB - For optimal mitochondrial activity, the mitochondrial proteome must be properly maintained or altered in response to developmental and environmental stimuli. Based on studies of yeast and humans, one of the key players in this control are m-AAA proteases, mitochondrial inner membrane-bound ATP-dependent metalloenzymes. This study focuses on the importance of m-AAA proteases in plant mitochondria, providing their first experimentally proven physiological substrate. We found that the Arabidopsis m- AAA complexes composed of AtFTSH3 and/or AtFTSH10 are involved in the proteolytic maturation of ribosomal subunit L32. Consequently, in the double Arabidopsis ftsh3/10 mutant, mitoribosome biogenesis, mitochondrial translation and functionality of OXPHOS (oxidative phosphorylation) complexes are impaired. However, in contrast to their mammalian or yeast counterparts, plant m AAA complexes are not critical for the survival of Arabidopsis under optimal conditions; ftsh3/10 plants are only slightly smaller in size at the early developmental stage compared with plants containing m-AAA complexes. Our data suggest that a lack of significant visible morphological alterations under optimal growth conditions involves mechanisms which rely on existing functional redundancy and induced functional compensation in Arabidopsis mitochondria. PMID- 29462459 TI - Evidence that Myotis lucifugus "Subspecies" are Five Nonsister Species, Despite Gene Flow. AB - While genetic exchange between nonsister species was traditionally considered to be rare in mammals, analyses of molecular data in multiple systems suggest that it may be common. Interspecific gene flow, if present, is problematic for phylogenetic inference, particularly for analyses near the species level. Here, we explore how to detect and account for gene flow during phylogeny estimation using data from a clade of North American Myotis bats where previous results have led researchers to suspect that gene flow among lineages is present. Initial estimates of phylogenetic networks and species trees indicate that subspecies described within Myotis lucifugus are paraphyletic. In order to explore the extent to which gene flow is likely to interfere with phylogeny estimation, we use posterior predictive simulation and a novel Approximate Bayesian Computation approach based on gene tree distances. The former indicates that the species tree model is a poor fit to the data, and the latter provides evidence that a species tree with gene flow is a better fit. Taken together, we present evidence that the currently recognized M. lucifugus subspecies are paraphyletic, exchange alleles with other Myotis species in regions of secondary contact, and should be considered independent evolutionary lineages despite their morphological similarity. PMID- 29462460 TI - An interview with Professor Bert O' Malley. PMID- 29462461 TI - Identification and characterization of the proteins in broth of stewed traditional Chinese yellow-feathered chickens. AB - Soups and broths are popular in the world due to their nutrition and flavor, and flavor compounds tend to be bound by the proteins in the soups and broth, influencing the flavor perception. Thus, identification of the major proteins in meat-based broth may present a basis for understanding protein adsorption of flavor compounds. The present study aimed to identify the major proteins in traditional Chinese chicken broth and to describe the structural changes of proteins during stewing (1, 2, or 3 h). As stewing time increased, protein content in the broth significantly increased. Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) indicated that the macro-molecule proteins (>10 kDa) in the broth were mainly gelatin and actin and that the micro molecule proteins fractions (<10 kDa) increased substantially. The gelatin had an ordered structure even after 3 h of stewing, as seen by circular dichroism (CD) spectroscopy. The presence of reactive sulfhydryl groups increased remarkably with stewing time. The surface hydrophobicity of the proteins significantly increased within 2 h then deceased slightly after 3 h. The intermolecular crosslinks, as indicated by dispersion index, increased remarkably, consistent with the result of atomic force microscopy (AFM), which together suggested that protein aggregation increased during stewing. These findings suggested that gelatin was the structural protein in the broth system and that intermolecular crosslinks functioned to maintain the broth system. PMID- 29462462 TI - Effects of supplementation with alpha-tocopherol, ascorbic acid, selenium, or their combination in linseed oil-enriched diets on the oxidative status in broilers. AB - A trial was conducted to investigate whether, and if so to what extent, the combined supplementation of vitamin E, vitamin C, and selenium was superior to their sole supplementation concerning the oxidative stress induced by a high n-3 dietary polyunsaturated fatty acids (PUFA) intake in broilers. Four hundred 21 day-old Ross 308 male broilers were allocated to 5 experimental groups fed the following linseed oil (5%)-enriched finisher diets: Cont (no supplement), +E (200 IU vitamin E/kg feed), +C (250 mg vitamin C/kg feed), +Se (0.2 mg selenium/kg feed), or +ECSe (concentrations as in the sole supplementation, combined). Analyses of malondialdehyde (MDA), vitamin C, and alpha- and gamma-tocopherols in plasma, antioxidant capacity of water- (ACW) and lipid- (ACL) soluble compounds in serum, and glutathione peroxidase (GPx) and superoxide dismutase (SOD) activities in whole blood were performed. In breast muscle, analyses of MDA, alpha- and gamma-tocopherols, ACW, selenium, and fatty acid (FA) composition were carried out. Birds fed the combination of antioxidants showed reduced average daily gain (ADG) and average daily feed intake (ADFI) and, as +E, lower MDA and gamma-tocopherol, together with raised alpha- tocopherol levels in plasma and lower MDA and raised alpha- tocopherol levels in breast muscle compared to the control. The combination of antioxidants in the +ECSe group raised GPx activity in whole blood compared to the control. In conclusion, results indicated that vitamin E is the most effective antioxidant to alleviate oxidative stress caused by high dietary PUFA and that the supplementation with additional vitamin C and selenium did not have clear synergistic effect. PMID- 29462464 TI - Determining Brain Mechanisms that Underpin Analgesia Induced by the Use of Pain Coping Skills. AB - Objective: Cognitive behavioral therapies decrease pain and improve mood and function in people with osteoarthritis. This study assessed the effects of coping strategies on the central processing of knee pain in people with osteoarthritis of the knees. Methods: Mechanical pressure was applied to exacerbate knee pain in 28 people with osteoarthritis of the knee. Reports of pain intensity and functional magnetic resonance imaging measures of pain-related brain activity were recorded with and without the concurrent use of pain coping skills. Results: Coping skills led to a significant reduction in pain report (Coping = 2.64 +/- 0.17, Not Coping = 3.28 +/- 0.15, P < 0.001). These strategies were associated with increased activation in pain modulatory regions of the brain (medial prefrontal and rostral anterior cingulate cortices, Pcorrected < 0.05) and decreased pain-related activation in regions that process noxious input (midcingulate cortex, supplementary motor area, secondary somatosensory cortex, and anterior parietal lobule, Pcorrected < 0.05). The magnitude of the decrease in pain report during the use of pain coping strategies was found to be proportional to the decrease in pain-related activation in brain regions that code the aversive/emotional dimension of pain (anterior insula, inferior frontal gyrus, orbitofrontal cortex, Pcorrected < 0.05) but did not differ between groups with and without training in coping skills. However, training in coping skills reduced the extent to which brain responses to noxious input were influenced by anxiety. Conclusions: The results of this study support previous reports of pain modulation by cognitive pain coping strategies and contribute to the current understanding of how analgesia associated with the use of pain coping strategies is represented in the brain. PMID- 29462463 TI - TYPLEX(r) Chelate, a novel feed additive, inhibits Campylobacter jejuni biofilm formation and cecal colonization in broiler chickens. AB - Reducing Campylobacter spp. carriage in poultry is challenging, but essential to control this major cause of human bacterial gastroenteritis worldwide. Although much is known about the mechanisms and route of Campylobacter spp. colonization in poultry, the literature is scarce on antibiotic-free solutions to combat Campylobacter spp. colonization in poultry. In vitro and in vivo studies were conducted to investigate the role of TYPLEX(r) Chelate (ferric tyrosine), a novel feed additive, in inhibiting Campylobacter jejuni (C. jejuni) biofilm formation and reducing C. jejuni and Escherichia coli (E. coli) colonization in broiler chickens at market age. In an in vitro study, the inhibitory effect on C. jejuni biofilm formation using a plastic bead assay was investigated. The results demonstrated that TYPLEX(r) Chelate significantly reduces biofilm formation. In an in vivo study, 800 broilers (one d old) were randomly allocated to 4 dietary treatments in a randomized block design, each having 10 replicate pens with 20 birds per pen. At d 21, all birds were challenged with C. jejuni via seeded litter. At d 42, cecal samples were collected and tested for volatile fatty acid (VFA) concentrations and C. jejuni and E. coli counts. The results showed that TYPLEX(r) Chelate reduced the carriage of C. jejuni and E. coli in poultry by 2 and 1 log10 per gram cecal sample, respectively, and increased cecal VFA concentrations. These findings support TYPLEX(r) Chelate as a novel non antibiotic feed additive that may help produce poultry with a lower public health risk of Campylobacteriosis.

PMID- 29462466 TI - Effect of pre-slaughter shackling and wing flapping on plasma parameters, postmortem metabolism, AMPK, and meat quality of broilers. AB - The objective of this study was to determine the effects of shackling and wing flapping on stress, postmortem metabolism, AMP-activated protein kinase (AMPK), and quality of broiler pectoralis major. Before slaughter, a total of 80 Arbor Acres broilers was randomly categorized into 2 replicate pens (40 broilers per pen) and each pen randomly divided into 2 groups (shackling, T; control, C). Corticosterone, creatine kinase, and lactate dehydrogenase were determined on blood plasma parameters. Pectoralis major were removed after evisceration and used for determination of energy metabolism, meat quality, and AMPK phosphorylation. In this study, shackling and wing flapping increased (P < 0.05) plasma corticosterone level, creatine kinase activity, and lactate dehydrogenase activity. Shackling and wing flapping increased (P < 0.05) AMPKalpha(Thr172) and acetyl-CoA carboxylase (ACC) phosphorylation, followed by rapid glycolysis and accumulation of lactic acid, and leading to a fast pH decline in the initial postmortem meat. Shackling and wing flapping have an adverse effect on final meat quality, which increased (P < 0.05) muscle lightness, drip loss, and cooking loss. The results indicate that antemortem shackling and wing flapping increased stress and AMPKalpha(Thr172) phosphorylation, which may accelerate glycolysis and lead to a low water-holding capacity of broiler meat. PMID- 29462467 TI - Secundum Atrial Septal Defect. PMID- 29462468 TI - The impact of vitamin D status and parameters of calcium metabolism in patients with primary hyperparathyroidism. AB - Background: There is ample evidence associating vitamin D deficiency in primary hyperparathyroidism (PHP) patients with more severe disease manifestations and increased risk of postoperative hypocalcemia. Yet, there is limited data regarding the safety of vitamin D repletion in these patients. Aim: To assess the safety of vitamin D repletion in PHP patients in a real-world setting. Design: We included patients with asymptomatic PHP and few symptomatic patients who declined surgery, followed in our clinic, and treated on a routine basis with 2000 IU/day of vitamin D3. Methods: Serum calcium (sCa), PTH, 25-hydroxyvitamin D, and 24 h urinary calcium (uCa) and creatinine collections were compared between the lowest and the highest vitamin D time points. Results: There were 40 patients of a mean age was 63 +/- 10 years. 25(OH)D at lowest and highest vitamin D time points was 15.5 +/- 6.2 ng/ml and 33.2 +/- 8, respectively (P < 0.001). Serum calcium was not affected by the changes in vitamin D levels. In none of the patients did sCa exceed 11.5 mg/dL. uCa was 220 +/- 110 mg/24 h at the lowest vitamin D time point and 260 +/- 140 at the highest vitamin D time point (P = 0.14). uCa exceeded 400 mg/24 h in two vs. five patients (P = 0.23) at the lowest and highest vitamin D time points, respectively. PTH was not significantly different between the different vitamin D time points. Discussion/Conclusion: Vitamin D repletion in PHP seems safe. Considering the documented adverse influence of vitamin D deficiency in PHP, particularly on skeletal manifestations and on the postoperative course, vitamin D repletion is warranted.

PMID- 29462471 TI - The use of panoramic radiographs to decide when interceptive extraction is beneficial in children with palatally displaced canines based on a randomized clinical trial. AB - Objective: To evaluate which palatally displaced canines (PDCs) benefit from interceptive extraction of the deciduous canine, to assess possible side effects from the extraction, and to analyse other dental deviations in patients with PDCs. Design, settings, participants, and intervention: A sample of 67 patients (40 girls, mean age: 11.3 +/- 1.1; 27 boys, mean age +/- SD: 11.4 +/- 0.9) with unilateral (45) or bilateral (22) PDCs were consecutively recruited and randomly allocated to extraction or non-extraction using block randomization. No patients dropped out after randomization or during the study. The patients were given a clinical examination and panoramic radiographs were taken at baseline and after 6 (T1) and 12 months (T2). An individual therapy plan was made for the PDCs that had not erupted at T2. Measurements were performed blindly and the outcome measures were: canine position and angulation, root development, midline shift, rotation, or movement of adjacent teeth into the extraction site, and frequency of other dental deviations. Results: Interceptive deciduous canine extraction is beneficial if the alpha angle is between 20 and 30 degrees. A PDC located in sector 4 with an alpha angle >30 degrees should have immediate surgical exposure, while canines angulated less than 20 degrees and located in sector 2 can be observed without prior interceptive extraction. Deciduous canine extraction was more beneficial in younger patients with less advanced root development. Minor side effects, such as rotation or migration of teeth into the extraction space, were observed in 15 out of 35 patients. A majority of the patients had other dental deviations than PDC in the dentition. Limitations: The results are only valid for patients with no space deficiency in the maxilla and with PDCs located in sector 2-4. Harms: No harms were detected. Conclusions: The alpha angle and sector position are good diagnostic predictors of when interceptive extraction is beneficial. Minor side effects are seen after the extraction and the majority of the patients had other dental deviations too. Registration: This trial was registered at http://www.fou.nu/is/sverige, registration number: 211141. PMID- 29462472 TI - Functionally Diversified Members of the MIR165/6 Gene Family Regulate Ovule Morphogenesis in Arabidopsis thaliana. AB - The ovules of flowering plants consist of a central embryo sac and surrounding layers of the inner and outer integument. As these structural units eventually give rise to the embryo/endosperm and seed coat, respectively, a precisely organized ovule structure is essential for successful fertilization and seed production. In Arabidopsis thaliana, correct ovule patterning depends on the restricted expression of the CLASS III HOMEODOMAIN LEUCINE ZIPPER (HD-ZIP III) gene PHABULOSA (PHB) in the apical region of the incipient inner integument, which in turn is regulated via post-transcriptional suppression by miR165 and miR166 (miR165/6) derived from multiple MIR165/6 genes. While a common subset of MIR165/6 genes regulate PHB expression in the root meristem, leaf primordium and embryo, it is unknown whether the same MIR165/6 subset also regulate PHB expression during ovule development. Furthermore, it is unclear where in the ovule primordia miR165/6 are produced. Here, we show that a distinct set of MIR165/6 genes that are highly expressed in the small regions of early ovule primordia restrict the PHB expression domain to promote integument formation. MIR165/6 genes that function in ovule development are phylogenetically distinct from those acting in roots and leaf primordia. Taken together, our data suggest that members of the MIR165/6 gene family are diversified in their expression capacity to establish elaborate PHB expression patterns depending on the developmental context, thereby allowing HD-ZIP III transcription factors to regulate multiple aspects of plant development.

Aim: To highlight the entity of acute, early onset corticosteroid-treatment associated myopathy and its characteristics. Design and Methods: Reporting our experience with four patients and reviewing all published reports of myopathy developing <=14 days of initiating corticosteroid-treatment. Results: Acute corticosteroid myopathy (ASM) exists, though the syndrome appears to be rare. It is characterized by unpredictability and heterogeneity, sometimes developing within 1-3 days, after a single dose, which may not be high and administered by varied routes. Proximal limb muscle weakness is the most common form, but distal limb, bulbar and respiratory muscles may be involved. Steroid cessation often leads to improvement/resolution, but irreversibility may occur. Conclusions: A high index of suspicion for the possibility of ASM is necessary to ensure drug discontinuation and recovery. This is particularly true since the entity is not widely recognized and its symptoms are often erroneously interpreted as due to the patient's underlying disease. PMID- 29462473 TI - Stochastic Pharmacokinetic-Pharmacodynamic Modeling for Assessing the Systemic Health Risk of Perfluorooctanoate (PFOA). AB - A phase 1 dose-escalation trial assessed the chemotherapeutic potential of ammonium perfluorooctanoate (APFO). Forty-nine primarily solid-tumor cancer patients who failed standard therapy received weekly APFO doses (50-1200 mg) for 6 weeks. Clinical chemistries and plasma PFOA (anionic APFO) were measured predose and weekly thereafter. Several clinical measures including total cholesterol, high-density lipoproteins (HDLs), thyroid stimulating hormone (TSH), and free thyroxine (fT4), relative to PFOA concentrations were examined by: Standard statistical analyses using generalized estimating equations (GEE) and a probabilistic analysis using probability distribution functions (pdf) at various PFOA concentrations; and a 2-compartment pharmacokinetic/pharmacodynamic (PK/PD) model to directly estimate mean changes. Based on the GEE, the average rates of change in total cholesterol and fT4 associated with increasing PFOA were approximately -1.2*10-3 mmol/l/MUM and 2.8*10-3 pmol/l/MUM, respectively. The PK/PD model predicted more closely the trends observed in the data as well as the pdfs of biomarkers. A decline in total cholesterol was observed, with a clear transition in shape and range of the pdfs, manifested by the maximum value of the Kullback-Leibler (KL) divergence, that occurred at plasma PFOA between 420 and 565 MUM (175 000-230 000 ng/ml). High-density lipoprotein was unchanged. An increase in fT4 was observed at a higher PFOA transition point, albeit TSH was unchanged. Our findings are consistent with some animal models and may motivate re-examination of the epidemiologic studies to PFOA at levels several orders of magnitude lower than this study. These observational studies have reported contrary associations, but currently understood biology does not support the existence of such conflicting effects. PMID- 29462476 TI - Malassezia pachydermatis up-regulates AhR related CYP1A1 gene and epidermal barrier markers in human keratinocytes. AB - Cytochrome P450 CYP1A1 and CYP1B1 enzymes are regulated by the aryl hydrocarbon receptor (AhR), a transcription factor activated by a variety of ligands among which Malassezia metabolites. In this study, we analyzed the modulation of CYP1A1, CYP1B1, and AhR in human keratinocytes infected with different strains of Malassezia pachydermatis, as well as the upregulation of some genes involved in the epidermal homeostasis. We demonstrated that all the strains induced AhR activation and its nuclear translocation in HaCaT cells infected for 24 h, compared to untreated cells. The expression of CYP1A1 and CYP1B1, prototypical markers of the AhR signaling pathway, were upregulated with the level of CYP1A1 mRNA approximately 100-fold greater than that for CYP1B1. Filaggrin, involucrin, and TGaseI, proteins involved in epidermal differentiation, were all modulated by Malassezia pachydermatis strains, with the strongest induction observed for filaggrin. By contrast, quinone oxidoreductase 1 (NQO1), which is part of the antioxidant defense system involved in detoxification, was not modulated in our experimental model. In conclusions, our findings suggest that Malassezia pachydermatis infection of human keratinocytes induces activation of the AhR, and increases the expression of its responsive genes and markers of epidermal differentiation, paving the way for occurrence/exacerbation of pathological skin conditions. PMID- 29462475 TI - Choosing to regulate: does choice enhance craving regulation? AB - Goal-directed behavior and lifelong well-being often depend on the ability to control appetitive motivations, such as cravings. Cognitive reappraisal is an effective way to modulate emotional states, including cravings, but is often studied under explicit instruction to regulate. Despite the strong prediction from Self-Determination Theory that choice should enhance task engagement and regulation success, little is known empirically about whether and how regulation is different when participants choose (vs are told) to exert control. To investigate how choice affects neural activity and regulation success, participants reappraised their responses to images of personally-craved foods while undergoing functional neuroimaging. Participants were either instructed to view or reappraise ('no-choice') or chose freely to view or reappraise ('yes choice'). Choice increased activity in the frontoparietal control network. We expected this activity would be associated with increased task engagement, resulting in better regulation success. However, contrary to this prediction, choice slightly reduced regulation success. Follow-up multivariate functional neuroimaging analyses indicated that choice likely disrupted allocation of limited cognitive resources during reappraisal. While unexpected, these results highlight the importance of studying upstream processes such as regulation choice, as they may affect the ability to regulate cravings and other emotional states.

AB - Meat from the Greater rhea (Rhea americana) could compete with traditional red meats, diversifying the market of protein products of animal origin. The meat from 32 rheas was used to study quality aspects and this included ultimate pH (pHu), color, water-holding capacity (WHC%), cooking loss (CL%) and tenderness. The muscles sampled were the Gastrocnemius pars externa, Iliofibularis and Obturatorius medialis from both sexes at multiple ages (10, 12, 14, 16 months). Age at slaughter affected WHC%, CL%, and color in raw meat and tenderness in cooked meat. Muscles under study showed differences in terms of pHu, raw meat color, and tenderness of cooked meat. Sex did not have a significant effect on any of the variables studied. According to our results, rhea meat from younger animals, between 10 to 14 months old, was tender and moderately juicy and the visual color was appreciated by the consumers. PMID- 29462479 TI - EVALUATION OF PATIENT EXPOSURE IN FAST kVp SWITCHING DUAL ENERGY COMPUTED TOMOGRAPHY: PHANTOM STUDY. AB - The aim of this study was to evaluate the suitability of size specific dose estimates (SSDE) to estimate patient dose in Fast kVp switching dual energy CT. An anthropomorphic phantom (RAN-110) was repeatedly scanned (chest, abdomen and the pelvis) using a 64 detector row MDCT (Discovery CT750 HD, GE Healthcare, Milwaukee, WI, USA) with various CT parameters, including Fast kVp switching. Dosimetry was performed using thermo-luminescent dosimeters, positioned both superficially and within the phantom. SSDE was calculated for all slices of the anthropomorphic phantom using both the localiser and axial images. In Fast kVp switching, SSDE underestimated the measured absorbed dose for the chest/abdomen region ~35% at the maximum, but were in closer agreement for the pelvic region about within 10%. In single energy techniques, SSDE could not be applied in the estimation of organ doses, but in Fast kVp switching dual energy techniques, SSDE could be applied for anatomical regions with larger thicknesses. PMID- 29462480 TI - Testicular histomorphometrics including Sertoli cell quantitation for evaluating hatchability and fertility issues in commercial breeder-broiler roosters. AB - Testicular histomorphometric methods were developed for the investigation of fertility and hatchability problems in commercial broiler-breeder roosters. Sertoli cell (SC) evaluations were emphasized in view of their role in influencing embryonic testicular organogenesis and spermatogenesis in adults. H&E stained sections prepared from formalized tissues were examined. SC evaluations were mostly made from computer generated images using image analysis software, but were also compared to direct counting with ocular grid reticle. Other measurements were germinal epithelial and total seminiferous tubule widths, quantification of individual spermatozoa and sperm clusters, and determinations of stromal area. Age-associated changes in SC occurred between 15 to 54 wk of age. A significant reduction in SC concentration occurred at 29 wk of age (P < 0.001) that corresponded with the histologic initiation of spermatogenesis. Expanded morphometric evaluations were performed on 59-week-old roosters comparing a flock having good body condition and footpad scores with normal testicular and body weights (optimal profile or OP group) to a second flock demonstrating relatively poor expression of these parameters and decreased fertility (sub-optimal profile or SOP group). Significant reductions (P < 0.05) in SC concentration, spermatozoa, and tubular widths, but an increased percentage of stroma area occurred in SOP compared to OP flocks. SC results also correlated well with testes weight. A unique finding was a significant relationship between decreasing SC concentration and increasing severity scores for footpad lesions. Differences in all histomorphometric parameters occurred between flocks demonstrating good hatchability compared to flocks exhibiting either low or decreasing hatchability. Significant reductions in SC and other morphometric parameters were observed for the poor relative to good hatchability group. A strong positive association was observed for SC results using computer generated images and direct reticle ocular counting (R = 0.80). Replicate counts on control sections demonstrated generally good reproducibility of methods between experiments. The findings are supportive of the value of testicular histomorphometrics for evaluations of hatchability issues in commercial roosters. PMID- 29462481 TI - Greater involvement of action simulation mechanisms in emotional versus cognitive empathy. AB - Empathy is crucial for successful interpersonal interactions, and it is impaired in many psychiatric and neurological disorders. Action-perception matching, or action simulation mechanisms, have been suggested to facilitate empathy by supporting the simulation of perceived experience in others. However, this remains unclear, and the involvement of the action simulation circuit in cognitive empathy (the ability to adopt another's perspective) versus emotional empathy (the capacity to share and react affectively to another's emotional experience) has not been quantitatively compared. Presently, healthy adults completed a classic cognitive empathy task (false belief), an emotional empathy task, and an action simulation button-pressing task during fMRI. Conjunction analyses revealed common recruitment of the inferior frontal gyrus (IFG), thought to be critical for action-perception matching, during both action simulation and emotional, but not cognitive, empathy. Furthermore, activation was significantly greater in action simulation regions in the left IFG during emotional versus cognitive empathy, and activity in this region was positively correlated with mean feeling ratings during the emotional empathy task. These findings provide evidence for greater involvement of action simulation mechanisms in emotional than cognitive empathy. Thus, the action simulation circuit may be an important target for delineating the pathophysiology of disorders featuring emotional empathy impairments. PMID- 29462483 TI - ESTIMATION OF DIAGNOSTIC REFERENCE LEVELS FOR CT CORONAROGRAPHY IN SLOVAKIA. AB - The coronary CT angiography (CCTA) is a frequent diagnostic method connected with large variability of effective dose. Therefore, it is the type of examination where optimization is very important and the use of a national diagnostic reference level (DRL) recommended. In Slovakia the DRL for interventional radiology examinations until now fails. The objective of our study was to propose the national DRL for CCTA examinations in Slovak Republic, on the basis of a cross-sectional multicenter study, performed in four departments of radiology. The study was realized in 2014-16 in a sample of 1725 patients undergoing CCTA examination. The proposed DRL expressed by CTDIVOL is 45 mGy and of DLP is 510 mGy cm. PMID- 29462482 TI - A randomized Phase III trial of adjuvant S-1 therapy vs. observation alone in resected biliary tract cancer: Japan Clinical Oncology Group Study (JCOG1202, ASCOT). AB - No standard adjuvant treatment has been established for patients with curatively resected biliary tract cancer. S-1 has been reported to show promising efficacy with mild toxicity profiles in patients with advanced biliary tract cancer, and adjuvant S-1 therapy has been demonstrated to provide survival benefit in patients with resected gastric cancer and pancreatic cancer. The aim of this open label, multicenter, randomized Phase III trial is to confirm that adjuvant chemotherapy with S-1 would prolong overall survival in patients with resected biliary tract cancer. This study was activated in September 2013. A total of 350 patients planned to be enrolled from 36 Japanese institutions over a period of 4 years. At July 2017, the protocol was revised to increase power from 70% to 80%. Therefore, the planned total sample size is 440. The primary endpoint is overall survival. This trial is registered with the UMIN Clinical Trials Registry as UMIN000011688. PMID- 29462484 TI - A Review of Industry Funding in Randomized Controlled Trials Published in the Neurosurgical Literature-The Elephant in the Room. AB - OBJECTIVE: To analyze the role of industry sponsorship of randomized controlled trials (RCTs) published exclusively in 3 major North American neurosurgical journals. METHODS: Our primary objective was to determine whether an association exists between study conclusion(s) in favor of industry sponsored drugs, devices/implants, or surgical techniques and industry sponsorship. The secondary objective was to describe the quality/quantity of these neurosurgical RCTs. RESULTS: A total of 110 RCTs were analyzed, the majority were published in the Journal of Neurosurgery (85%) and were international in origin (55%). The most common subspecialty was spine (n = 29) and drug study was the most common type (n = 49). Overall quality was good with median Jadad and Detsky scores of 4 (range, 1-5) and 18 (range, 8-21), respectively. There was a statistically significant difference in RCTs with industry funding (31/40, 78%) versus those without (9/70, 13%) that published a favorable conclusion of the new drug, device/implant, or surgical technique (odds ratio [OR], 23.35; P < .0001). Multiple binomial logistic regression analysis identified "number of authors" as mildly protective (OR, 0.79; 95% confidence interval, 0.69-0.91; P = .001) and "industry funding" strongly predictive (OR, 12.34; 95% confidence interval, 2.97-51.29; P = .001) of a positive trial. CONCLUSION: Industry funding was associated with a much greater chance of positive findings in RCTs published in neurosurgical journals. Further efforts are needed to define the relationship between the authors and financial sponsors of neurosurgical research and explore the reasons for this finding.

AB - Livestock production systems have faced social pressures related to animal welfare; the laying hen industry also has faced changes in governing regulations/policies. This study employs experimental data to evaluate 3 confinement-housing systems: standard cages with no perches, cages with standard perches, and cages with cooled perches. Based on the cost-benefit analysis conducted of revenue less feed costs, operators are expected to have revenue, after covering feed costs, which could contribute to installation and maintenance of standard and/or cooled perches. Thus, egg producers may be able to use caged housing that incorporates perches profitably, depending on the final costs of such a system. PMID- 29462487 TI - Structural change of ovalbumin-related protein X by alkali treatment. AB - Chicken egg white protein ovalbumin (OVA) undergoes a conversion to a more thermostable form by alkali treatment, which is assumed to be involved in the physiological functions of OVA. Ovalbumin-related protein X (OVAX), a chicken egg white protein, has 77% sequence similarity to OVA and binds to heparin. In this study, structure characteristics and heparin-binding affinity of alkali-treated OVAX were investigated. Cation-exchange chromatography using SP Sepharose resin showed that alkali treatment (pH 10, 55 degrees C) of OVAX induces the occurrence of a distinct OVAX form with a less positive-charge (acidic OVAX). Circular dichroism and tryptophan-fluorescence analyses showed that the newly-formed acidic OVAX form has an 8% lower alpha-helical content than its native counterpart, while there is no significant difference in steric environments around tryptophan residues between the 2 forms. The OVAX structure built by homology-modeling showed that OVAX possess a basic cluster domain with alpha helix equivalent to 7% of total secondary structures, which does not contain any tryptophan residues. These results suggest that, during alkali treatment, OVAX undergoes mainly a conformational change of the alpha-helical basic cluster domain and thereby forms acidic OVAX. Acidic OVAX induced by alkali treatment exhibited weaker interactions with Heparin Sepharose resin than native OVAX did. Our results suggest that OVAX basic cluster domain is likely a specific binding site of heparin. Consequently, it is suggested that alkali treatment causes the collapse of the OVAX heparin binding site, which might participate in regulating the functions of heparin. PMID- 29462488 TI - Computational model for behavior shaping as an adaptive health intervention strategy. AB - Adaptive behavioral interventions that automatically adjust in real-time to participants' changing behavior, environmental contexts, and individual history are becoming more feasible as the use of real-time sensing technology expands. This development is expected to improve shortcomings associated with traditional behavioral interventions, such as the reliance on imprecise intervention procedures and limited/short-lived effects. JITAI adaptation strategies often lack a theoretical foundation. Increasing the theoretical fidelity of a trial has been shown to increase effectiveness. This research explores the use of shaping, a well-known process from behavioral theory for engendering or maintaining a target behavior, as a JITAI adaptation strategy. A computational model of behavior dynamics and operant conditioning was modified to incorporate the construct of behavior shaping by adding the ability to vary, over time, the range of behaviors that were reinforced when emitted. Digital experiments were performed with this updated model for a range of parameters in order to identify the behavior shaping features that optimally generated target behavior. Narrowing the range of reinforced behaviors continuously in time led to better outcomes compared with a discrete narrowing of the reinforcement window. Rapid narrowing followed by more moderate decreases in window size was more effective in generating target behavior than the inverse scenario. The computational shaping model represents an effective tool for investigating JITAI adaptation strategies. Model parameters must now be translated from the digital domain to real-world experiments so that model findings can be validated. PMID- 29462490 TI - Open surgical repair of post-dissection thoraco-abdominal aortic aneurysms: early and late outcomes of a single-centre study involving over 200 patients. AB - OBJECTIVES: Chronic, post-dissection thoraco-abdominal aortic aneurysms (TAAAs) are increasingly being treated by (hybrid) endovascular means. Although it is less invasive, thoracic endovascular aortic repair is technically complex with the risk of incomplete aneurysm exclusion, necessitating frequent reinterventions with potentially reduced long-term outcomes. The aim of this study was to evaluate contemporary early and late outcomes after open surgical repair of post dissection TAAA. METHODS: At our centre, 633 patients underwent open repair for TAAA over a 20-year period (1994-2015), including 217 (34%) patients for post dissection TAAA, who were included in this analysis. Circulatory support was obtained by either left heart bypass (173 patients, 79.7%), deep hypothermic circulatory arrest (41 patients, 18.9%) or simple aortic cross-clamping in 3 patients. We analysed all relevant perioperative and intraoperative variables with respect to adverse outcomes. Additionally, long-term survival and the need for aortic reinterventions were studied. RESULTS: The mean age was 60.2 +/- 11.9 years (men 68.2%). We identified 66 Type I (30.4%), 113 Type II (52.1%), 25 Type III (11.5%), 10 Type IV (4.6%) and 3 Type V (1.4%) TAAAs. Early mortality and spinal cord deficit were 5.9% and 5.5%, respectively. Follow-up was 100% complete (mean 6.0 +/- 5.8 years), with long-term survival of 71.4% at 10 years, and freedom from death and reoperation was 68.2% at 10 years. CONCLUSIONS: Although it is more invasive than current endovascular approaches for post-dissection TAAA, open surgical repair can be performed safely with acceptable rates of morbidity and mortality when it is done in a specialized aortic centre. Long-term survival and freedom from aortic reintervention are excellent and should also be taken into account when evaluating less invasive alternatives. PMID- 29462489 TI - DNA methylation dynamics of genomic imprinting in mouse development. AB - DNA methylation is an essential epigenetic mark crucial for normal mammalian development. This modification controls the expression of a unique class of genes, designated as imprinted, which are expressed monoallelically and in a parent-of-origin-specific manner. Proper parental allele-specific DNA methylation at imprinting control regions (ICRs) is necessary for appropriate imprinting. Processes that deregulate DNA methylation of imprinted loci cause disease in humans. DNA methylation patterns dramatically change during mammalian development: first, the majority of the genome, with the exception of ICRs, is demethylated after fertilization, and subsequently undergoes genome-wide de novo DNA methylation. Secondly, after primordial germ cells are specified in the embryo, another wave of demethylation occurs, with ICR demethylation occurring late in the process. Lastly, ICRs reacquire DNA methylation imprints in developing germ cells. We describe the past discoveries and current literature defining these crucial dynamics in relation to imprinted genes and the rest of the genome. PMID- 29462491 TI - The beta-adrenergic agonist salbutamol modulates neuromuscular junction formation in zebrafish models of human myasthenic syndromes. AB - Inherited defects of the neuromuscular junction (NMJ) comprise an increasingly diverse range of disorders, termed congenital myasthenic syndromes (CMS). Therapies acting on the sympathetic nervous system, including the selective beta2 adrenergic agonist salbutamol and the alpha and beta adrenergic agonist ephedrine, have become standard treatment for several types of CMS. However, the mechanism of the therapeutic effect of sympathomimetics in these disorders is not understood. Here, we examined the effect of salbutamol on NMJ development using zebrafish with deficiency of the key postsynaptic proteins Dok-7 and MuSK. Treatment with salbutamol reduced motility defects in zebrafish embryos and larvae. In addition, salbutamol lead to morphological improvement of postsynaptic acetycholine receptor (AChR) clustering and size of synaptic contacts in Dok-7 deficient zebrafish. In MuSK-deficient zebrafish, salbutamol treatment reduced motor axon pathfinding defects and partially restored the formation of aneural prepatterned AChRs. In addition, the effects of salbutamol treatment were prevented by pre-treatment with a selective beta2 antagonist. Treatment with the cyclic adenosine monophosphate (cAMP) activator forskolin, replicated the effects of salbutamol treatment. These results suggest that sympathomimetics exert a direct effect on neuromuscular synaptogenesis and do so via beta2 adrenoceptors and via a cAMP-dependent pathway. PMID- 29462492 TI - Chronic Helminth Infection Perturbs the Gut-Brain Axis, Promotes Neuropathology, and Alters Behavior. AB - Helminth infections in children are associated with impaired cognitive development; however, the biological mechanisms for this remain unclear. Using a murine model of gastrointestinal helminth infection, we demonstrate that early life exposure to helminths promotes local and systemic inflammatory responses and transient changes in the gastrointestinal microbiome. Behavioral and cognitive analyses performed 9-months postinfection revealed deficits in spatial recognition memory and an anxiety-like behavioral phenotype in worm-infected mice, which was associated with neuropathology and increased microglial activation within the brain. This study demonstrates a previously unrecognized mechanism through which helminth infections may influence cognitive function, via perturbations in the gut-immune-brain axis. PMID- 29462493 TI - Short delay in initiation of radiotherapy for patients with glioblastoma-effect of concurrent chemotherapy: a secondary analysis from the NRG Oncology/Radiation Therapy Oncology Group database. AB - Background: We previously reported the unexpected finding of significantly improved survival for newly diagnosed glioblastoma in patients when radiation therapy (RT) was initiated later (>4 wk post-op) compared with earlier (<=2 wk post-op). In that analysis, data were analyzed from 2855 patients from 16 NRG Oncology/Radiotherapy Oncology Group (RTOG) trials conducted prior to the era of concurrent temozolomide (TMZ) with RT. We now report on 1395 newly diagnosed glioblastomas from 2 studies, treated with RT and concurrent TMZ followed by adjuvant TMZ. Our hypothesis was that concurrent TMZ has a synergistic/radiosensitizing mechanism, making RT timing less significant. Methods: Data from patients treated with TMZ-based chemoradiation from NRG Oncology/RTOG 0525 and 0825 were analyzed. An analysis comparable to our prior study was performed to determine whether there was still an impact on survival by delaying RT. Overall survival (OS) was investigated using the Kaplan-Meier method and Cox proportional hazards model. Early progression (during time of diagnosis to 30 days after RT completion) was analyzed using the chi-square test. Results: Given the small number of patients who started RT early following surgery, comparisons were made between >4 and <=4 weeks delay of radiation from time of operation. There was no statistically significant difference in OS (hazard ratio = 0.93; P = 0.29; 95% CI: 0.80-1.07) after adjusting for known prognostic factors (recursive partitioning analysis and O6-methylguanine-DNA methyltransferase methylation status). Similarly, the rate of early progression did not differ significantly (P = 0.63). Conclusions: We did not observe a significant prognostic influence of delaying radiation when given concurrently with TMZ for newly diagnosed glioblastoma. The effects of early (1-3 wk post-op) or late (>5 wk) initiation of radiation tested in our prior study could not be replicated. PMID- 29462494 TI - Why did severe feather pecking and cannibalism outbreaks occur? An unintended case study while investigating the effects of forage and stress on pullets during rearing. AB - This 2 * 2 factorial experiment aimed to investigate the effects of stimulating foraging behavior from wk 6 and imposed stress at wk 16 on the development of severe feather pecking (SFP) in chickens reared for free-range egg production. Non-beak-trimmed ISA Brown chicks were purchased at one day old and floor-reared on wood shavings. From wk 6, straw was provided daily in dispensers (Forage vs. No forage) to stimulate foraging. At wk 15, there were 16 pens of 50 pullets. "Stressors" were applied to half the pens in wk 16 via combined transport, relocation, and mixing (TRM) of pullets, simulating activities around transfer from the rearing to egg-laying farm (TRM vs. Not TRM). Range access was permitted from wk 21. Behavior, plumage damage (PD), growth, egg production, feed use, injuries, and mortalities were recorded, along with litter moisture and pH. In wk 26, an SFP outbreak commenced. By wk 34, PD was worse in south- than north-aspect pens (P < 0.001). Further, PD was more affected by side of the shed than the experimental treatments. In wk 30, an outbreak of injurious pecking (IP) commenced in the 4 TRM-treatment pens on the south side, with IP deaths almost 3 times more common in the Forage+TRM than No forage+TRM treatment. We suggest factors associated with a 13-day rainfall event that occurred in late winter predisposed the flock to SFP. While multiple factors such as winter cold, muddy ranges, damp floor litter with elevated pH, among others coincided, hens were clearly more impacted in south- than north-aspect pens. Once initiated, SFP possibly spread via social learning, and by wk 40, ~98% of hens had PD. Interestingly, the IP outbreak was related to a combination of factors (stressors?), such as being housed in colder, damper south-aspect pens (note: southern hemisphere), having added Forage, and TRM. These unexpected relationships could help direct future research to identify the specific factors involved in the causation of SFP and IP/cannibalism outbreaks. PMID- 29462496 TI - Experiences and unmet needs of lesbian, gay, and bisexual people with cancer care: A systematic review and meta-synthesis. AB - OBJECTIVES: To explore the cancer care experiences and unmet needs of people who identify as a sexual or gender minority. METHODS: A qualitative systematic review and meta-synthesis was undertaken based on a registered protocol. Following literature searching and study selection, study quality was examined by using the Critical Appraisal Skill Programme Checklist. Qualitative data were extracted verbatim from included studies and synthesized by using thematic analysis. RESULTS: Fifteen studies that included lesbian, gay, and bisexual (LGB) people living with or beyond cancer were included in the review. Studies including gender minorities were not identified. Most of the study participants were sexual minority women with breast cancer or sexual minority men with prostate cancer. Meta-synthesis of 106 individual findings generated 6 overarching themes pertaining to sexual orientation disclosure, experiences and fear of homophobia, positive and negative health-care professional behaviors, heterocentric systems and care, inadequacy of available support groups, and unmet needs for patient centered care and LGB-specific information. Lesbian, gay, and bisexual people often reported feelings of anxiety, invisibility, isolation, and frustration throughout the cancer care continuum. CONCLUSIONS: Analysis of the experiences of LGB people with cancer care shows that LGB people face numerous challenges due to their sexual orientation and receive care that does not adequately address their needs. Training and education of health-care professionals are strongly recommended to address some of these challenges and practice gaps. Culturally appropriate care includes avoiding heterosexual assumptions, use of inclusive language, the provision of tailored information, and involving partners in care. PMID- 29462495 TI - Comparison of Methods for Molecular Species Delimitation Across a Range of Speciation Scenarios. AB - Species are fundamental units in biological research and can be defined on the basis of various operational criteria. There has been growing use of molecular approaches for species delimitation. Among the most widely used methods, the generalized mixed Yule-coalescent (GMYC) and Poisson tree processes (PTP) were designed for the analysis of single-locus data but are often applied to concatenations of multilocus data. In contrast, the Bayesian multispecies coalescent approach in the software Bayesian Phylogenetics and Phylogeography (BPP) explicitly models the evolution of multilocus data. In this study, we compare the performance of GMYC, PTP, and BPP using synthetic data generated by simulation under various speciation scenarios. We show that in the absence of gene flow, the main factor influencing the performance of these methods is the ratio of population size to divergence time, while number of loci and sample size per species have smaller effects. Given appropriate priors and correct guide trees, BPP shows lower rates of species overestimation and underestimation, and is generally robust to various potential confounding factors except high levels of gene flow. The single-threshold GMYC and the best strategy that we identified in PTP generally perform well for scenarios involving more than a single putative species when gene flow is absent, but PTP outperforms GMYC when fewer species are involved. Both methods are more sensitive than BPP to the effects of gene flow and potential confounding factors. Case studies of bears and bees further validate some of the findings from our simulation study, and reveal the importance of using an informed starting point for molecular species delimitation. Our results highlight the key factors affecting the performance of molecular species delimitation, with potential benefits for using these methods within an integrative taxonomic framework. PMID- 29462497 TI - Accuracy of self-reported hypertension in Brazilian adolescents: Analysis of the Study of Cardiovascular Risk in Adolescents. AB - Given the high prevalence of hypertension in adolescents, it is important to investigate alternatives for estimating the magnitude of the disease. Our objective was to investigate the accuracy of self-reported hypertension. The study assessed participants of the Study of Cardiovascular Risk in Adolescents (ERICA). The following were calculated: sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). The associations between inaccurate self-reporting and socioeconomic factors were investigated. The accuracy of self-reported hypertension had a sensitivity of 7.5% (95% CI, 6.9 8.2), a specificity of 96.6% (95% CI, 96.5-96.7), a PPV of 18.9% (95% CI, 17.4 20.5), and a NPV of 90.8% (95% CI, 90.6-91.0). The prevalence of inaccurate self reported hypertension was smaller among girls (PR 0.68; 95% CI, 0.55-0.83) and younger boys (PR 0.68; 95% CI, 0.54-0.86) who were attending private schools. The use of self-reported hypertension was not a good strategy for investigating the hypertension in adolescents. PMID- 29462498 TI - Odorant Receptor 7D4 Activation Dynamics. AB - Deciphering how an odorant activates an odorant receptor (OR) and how changes in specific OR residues affect its responsiveness are central to understanding our sense of smell. A joint approach combining site-directed mutagenesis and functional assays with computational modeling has been used to explore the signaling mechanics of OR7D4. In this OR, a genetic polymorphism affects our perception of androstenone. Molecular simulations totaling 0.12 ms predicted that, similarly to observations for other G-protein-coupled receptors with known experimental structures, an activation pathway connects the ligand and the G protein binding site. The 3D model activation mechanism correlates with in vitro data and notably predicts that the OR7D4 WM variant is not activated. Upon activation, an OR-specific sequence motif is the convergence point of the mechanism. Our study suggests that robust homology modeling can serve as a powerful tool to capture OR dynamics related to smell perception.

AB - OBJECTIVE: In this retrospective investigation of patient pathways to psycho oncological treatment (POT), we compared the number of POT referrals before and after implementation of electronic screening for POT needs and investigated psychosocial predictors for POT wish at a nuclear medicine department. METHODS: We extracted medical chart information about number of referrals and extent of follow-up contacts. During standard referral (November 2014 to October 2015), POT needs were identified by clinical staff only. In the screening-assisted referral period (November 2015 to October 2016), identification was supported by electronic screening for POT needs. Psychosocial predictors for POT wish were examined using logistic regression. RESULTS: We analysed data from 487 patients during standard referral (mean age 56.4 years; 60.2% female, 88.7% thyroid carcinoma or neuroendocrine tumours) of which 28 patients (5.7%) were referred for POT. Of 502 patients in the screening-assisted referral period (mean age 57.0 years; 55.8% female, 86.6% thyroid carcinoma or neuroendocrine tumours), 69 (13.7%) were referred for POT. Of these, 36 were identified by psycho-oncological (PO) screening and 33 by clinical staff. After PO-screening implementation, referrals increased by a factor of 2.4. The strongest predictor of POT wish was depressive mood (P < .001). During both referral periods, about 15% of patients visited the PO outpatient unit additionally to inpatient PO consultations. CONCLUSIONS: Our results provide evidence from a real-life setting that PO screening can foster POT referrals, reduce barriers to express the POT wish, and hence help to meet psychosocial needs of this specific patient group. Differences between patients' needs, wish, and POT uptake should be further investigated. PMID- 29462500 TI - Antifibrinolytic drugs for treating primary postpartum haemorrhage. AB - BACKGROUND: Postpartum haemorrhage (PPH) - heaving bleeding within the first 24 hours after giving birth - is one of the main causes of death of women after childbirth. Antifibrinolytics, primarily tranexamic acid (TXA), have been shown to reduce bleeding in surgery and safely reduces mortality in trauma patients with bleeding without increasing the risk of adverse events.An earlier Cochrane review on treatments for primary PPH covered all the various available treatments - that review has now been split by types of treatment. This new review concentrates only on the use of antifibrinolytic drugs for treating primary PPH. OBJECTIVES: To determine the effectiveness and safety of antifibrinolytic drugs for treating primary PPH. SEARCH METHODS: We searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) (28 May 2017) and reference lists of retrieved studies. SELECTION CRITERIA: Randomised controlled trials (RCTs), including cluster-randomised trials of antifibrinolytic drugs (aprotinin, TXA, epsilon aminocaproic acid (EACA) and aminomethylbenzoic acid, administered by whatever route) for primary PPH in women.Participants in the trials were women after birth following a pregnancy of at least 24 weeks' gestation with a diagnosis of PPH, regardless of mode of birth (vaginal or caesarean section) or other aspects of third stage management.We have not included quasi-randomised trials, or cross over studies. Studies reported as abstracts have not been included if there was insufficient information to allow assessment of risk of bias.In this review we only identified studies looking at TXA. DATA COLLECTION AND ANALYSIS: Two review authors independently extracted data from each study using an agreed form. We entered data into Review Manager software and checked for accuracy.For key review outcomes, we rated the quality of the evidence as 'high', 'moderate', 'low' or 'very low' according to the GRADE approach. MAIN RESULTS: Three trials (20,412 women) met our inclusion criteria. Two trials (20,212 women) compared intravenous (IV) TXA with placebo or standard care and were conducted in acute hospital settings (labour ward, emergency department) (in high-, middle- and low-income countries).One other trial (involving 200 women) was conducted in Iran and compared IV TXA with rectal misoprostol, but did not report on any of this review's primary or GRADE outcomes. There were no trials that assessed EACA, aprotinin or aminomethylbenzoic acid.Standard care plus IV TXA for the treatment of primary PPH compared with placebo or standard care aloneTwo trials (20,212 women) assessed the effect of TXA for the treatment of primary PPH compared with placebo or standard care alone. The larger of these (The WOMAN trial) contributed over 99% of the data and was assessed as being at low risk of bias. The quality of the evidence varied for different outcomes, Overall, evidence was mainly graded as moderate to high quality.The data show that IV TXA reduces the risk of maternal death due to bleeding (risk ratio (RR) 0.81, 95% confidence interval (CI) 0.65 to 1.00; two trials, 20,172 women; quality of evidence: moderate). The quality of evidence was rated as moderate due to imprecision of effect estimate. The effect was more evident in women given treatment between one and three hours after giving birth with no apparent reduction when given after three hours (< one hour = RR 0.80, 95% CI 0.55 to 1.16; one to three hours = RR 0.60, 95% CI 0.41 to 0.88; > three hours = RR 1.07, 95% 0.76 to 1.51; test for subgroup differences: Chi2 = 4.90, df = 2 (P = 0.09), I2 = 59.2%). There was no heterogeneity in the effect by mode of birth (test for subgroup differences: Chi2 = 0.01, df = 1 (P = 0.91), I2 = 0%). There were fewer deaths from all causes in women receiving TXA, although the 95% CI for the effect estimate crosses the line of no effect (RR 0.88, 95% CI 0.74 to 1.05; two trials, 20,172 women, quality of evidence: moderate). Results from one trial with 151 women suggest that blood loss of >= 500 mL after randomisation may be reduced (RR 0.50, 95% CI 0.27 to 0.93; one trial, 151 women; quality of evidence: low). TXA did not reduce the risk of serious maternal morbidity (RR 0.99, 95% CI 0.83 to 1.19; one trial, 20,015 women; quality of evidence: high), hysterectomy to control bleeding (RR 0.95, 95% CI 0.81 to 1.12; one trial, 20,017 women; quality of evidence: high) receipt of blood transfusion (any) (RR 1.00, 95% CI 0.97 to 1.03; two trials, 20,167 women; quality of evidence: moderate) or maternal vascular occlusive events (any), although results were imprecise for this latter outcome (RR 0.88, 95% CI 0.54 to 1.43; one trial, 20,018 women; quality of evidence: moderate). There was an increase in the use of brace sutures in the TXA group (RR 1.19, 95% CI 1.01, 1.41) and a reduction in the need for laparotomy for bleeding (RR 0.64, 95% CI 0.49, 0.85). AUTHORS' CONCLUSIONS: TXA when administered intravenously reduces mortality due to bleeding in women with primary PPH, irrespective of mode of birth, and without increasing the risk of thromboembolic events. Taken together with the reliable evidence of the effect of TXA in trauma patients, the evidence suggests that TXA is effective if given as early as possible.Facilities for IV administration may not be available in non-hospital settings therefore, alternative routes to IV administration need to be investigated.

AB - Hepatocellular carcinoma (HCC) or liver cancer is an increasingly prevalent and highly morbid disease with critical significance in the Asian and African subcontinents. Among the various therapies currently used in the clinic to combat the global menace of HCC, radioembolization with suitable therapeutic isotopes is an effective targeted approach. In the Indian context, the significant cost and logistical disadvantage of imported radioembolic formulations for HCC therapy make it essential to develop more feasible indigenous alternatives-using locally available radioisotopes and microspheric carriers-that can serve the nuclear medicine community. With this aim Ho-166 was produced with good specific activity (>13 GBq mg-1 ) and purity (>99%) by reactor irradiation. Various commercially available microspheres were labeled with this therapeutic radioisotope, characterized for yield and stability of the radiolabeling, and tested for their in vivo retention and stability in Wistar rat model by viable surgery. Under the optimized reaction conditions, 166 Ho-labeled microspheres were prepared with high yield (>94%-99%) and in vitro stability (>95%) in saline and serum. Retention studies in animal model showed that 166 Ho-labeled microspheres remained stable in vivo and showed excellent retention in the site of interest (~95% at 72-hour p.i.). The study indicates good potential and warrants further investigation for application of these indigenous radiolabeled microspheres for HCC therapy. The successful application of this technology in the clinic would lead to logistically advantageous and cost-effective indigenous alternatives to expensive imported therapeutic solutions. PMID- 29462502 TI - Therapeutic Drug Monitoring of Biologics for Inflammatory Bowel Disease: An Answer to Optimized Treatment? AB - Therapeutic drug monitoring (TDM), or the measurement of drug concentrations in blood and antidrug antibodies, for biologic therapies used to treat inflammatory bowel disease (IBD) is an area of growing interest within the IBD community. When there is a definable relationship between drug concentration and clinical effect, blood concentration of biologics (and antidrug antibodies assessment) could be used to predict patient response and to titrate the biologics to maximize therapeutic benefit. This dose individualization has been proven to be more efficacious and cost-effective than empiric dose adjustment and can better guide therapeutic decisions regarding therapy withdrawal or switch. Appropriate implementation and interpretation of drug concentration measurement in TDM are essential to ensure full clinical benefit. Factors that need to be considered include sources of variability, timing of blood sampling, dosing history, analytical performance, immunogenicity, comedications, and clinical status of the patients. Desired target concentrations for biologics used in IBD have not been clearly determined yet. Published concentration thresholds differed widely for a given biologic, indicating a lack of consistent information. Factors other than drug concentration that may contribute to the dose-response variation are largely missing in the current TDM setting. A target range is likely preferable to a single value for TDM of biologics in IBD, and additional prospective research needs to be conducted in order to establish these ranges. Moving forward, TDM may be combined with pharmacodynamic end points and modeling and simulation tools for improved therapeutic benefit in IBD.

PMID- 29462505 TI - Neutrophil heterogeneity: Bona fide subsets or polarization states? AB - Neutrophils are key components of the innate immune system that play important roles during infection, injury, and chronic disease. In recent years, neutrophil heterogeneity has become an emerging focus with accumulating evidence of neutrophil populations with distinct functions under both steady-state and pathologic conditions. Despite these advances, it remains unclear whether these different populations represent bona fide subsets or simply activation/polarization states in response to local cues. In this review, we summarize the varied neutrophils populations that have been described under both basal and during inflammation. We discuss the evidence that supports the existence of neutrophils subsets. Finally, we identify potential gaps in our knowledge that may further advance our current understanding of neutrophil heterogeneity. PMID- 29462503 TI - Efficacy of a Spanish-Language Self-Administered Stress Management Training intervention for Latinas undergoing chemotherapy. AB - BACKGROUND: Cancer patients often report increased stress during chemotherapy. Stress management training has been shown to reduce this adverse outcome, but few interventions exist for Spanish-speaking Hispanic and Latina women (Latinas). METHODS: Following community feedback (including focus groups/in-depth interviews), we transcreated the Spanish-Language Self-Administered Stress Management Training (SL-SAT) intervention based on our previously developed and implemented English-based intervention. Latinas about to begin chemotherapy were randomized to SL-SAT (n = 121) or usual care (n = 119). A Spanish-speaking interventionist met with SL-SAT participants who received the SL-SAT toolkit containing instructions in 3 well-established stress management techniques (deep breathing, progressive muscle relaxation and guided imagery, and use of coping self-statements). Usual care participants received an educational booklet about coping with chemotherapy. All patients were instructed by nurses on their chemotherapy medications and given a resource listing of local support groups. Outcomes were obtained at baseline, and 7 and 13 weeks after starting chemotherapy. Primary outcomes included anxiety and depression, cancer-related distress, emotional well-being, and spiritual well-being. Secondary outcomes included functional well-being, social/family well-being, physical well-being, symptom severity, and self-efficacy for managing stress. Data were analyzed by using mixed models. RESULTS: In both groups, improvements were observed in emotional well-being (P = .01), and declines were observed in functional well being (P = .05), and physical well-being (P < .0001). Symptom severity increased across the follow-up period (P < .001). CONCLUSIONS: To be effective, stress management interventions for Latinas receiving chemotherapy may necessitate more attention from an interventionist, delivery of the intervention over a longer interval, and/or a group-based format.

PMID- 29462506 TI - Evaluation of Flexible Tacrolimus Drug Concentration Monitoring Approach in Patients Receiving Extended-Release Once-Daily Tacrolimus Tablets. AB - The majority of United States kidney transplant patients are treated with tacrolimus, a drug effective in preventing graft rejection, but with a narrow therapeutic range, necessitating close monitoring to avoid increased risks of transplant rejection or toxicity if the tacrolimus concentration is too low or too high, respectively. The trough drug concentration tests are time sensitive; patients treated on a twice-daily basis have blood draws exactly 12 hours after their previous dose. The schedule's rigidity causes problems for both patients and health care providers. Novel once-daily tacrolimus formulations such as LCPT (an extended-release tablet by Veloxis Pharmaceuticals, Inc., Cary, North Carolina) have allowed for blood draws on a once-daily basis; however, even that schedule can be restrictive. Results from tests taken either before or after that 24-hour target time may be discarded, or worse, may lead to inappropriate dose changes. Data from ASTCOFF, a phase 3B pharmacokinetic clinical trial (NCT02339246), demonstrated that the unique pharmacokinetic curve of LCPT may allow for a therapeutic monitoring window that extends for 3 hours before or after the 24-hour monitoring target. Furthermore, important tools to help clinicians interpret these levels, such as formulas to estimate the 24-hour trough level if an alternative monitoring time is used, were constructed from these data. These study results give treating clinicians access to data that allow them to safely use and monitor LCPT in their patients and expand the body of evidence surrounding differentiation and practical application of the novel LCPT tacrolimus formulation. PMID- 29462508 TI - Comparative effectiveness of an angiotensin receptor blocker, olmesartan medoxomil, in older hypertensive patients. AB - The efficacy and safety of olmesartan medoxomil (OM) vs active control (AC) monotherapy among elderly patients aged 60-79 years (N = 4487) was evaluated by meta-analysis (25 studies). In all patients, change from baseline to end point in blood pressure (BP) was significantly greater with OM vs AC (-19.5/-11.9 vs 16.8/-10.7 mm Hg). Greater proportions of OM- vs AC-treated patients achieved BP goals. In patients with impaired renal function (estimated glomerular filtration rate <60 mL/min/1.73 m2 ), OM treatment resulted in a greater mean change from baseline in systolic BP vs AC (-21.2 vs -18.7 mm Hg, respectively) and a greater proportion of patients achieving BP goals. These parameters were similar in both groups for elderly patients with diabetes. OM was well tolerated with few adverse events. OM monotherapy can be used as an initial treatment for hypertension in elderly patients, including those with renal impairment or diabetes. PMID- 29462509 TI - Theory Uncovers the Role of the Methionine-Tyrosine-Tryptophan Radical Adduct in the Catalase Reaction of KatGs: O2 Release Mediated by Proton-Coupled Electron Transfer. AB - Catalase-peroxidases (KatGs) are bifunctional enzymes exhibiting both peroxidase and substantial catalase activities. It is widely recognized from experiments that the catalatic activity of KatGs is correlated with a unique covalent adduct (M-Y-W) formed in the active site, but the exact role of this adduct was elusive up to now. Here, quantum mechanical/molecular mechanical (QM/MM) calculations and QM/MM metadynamics are employed to elucidate the molecular mechanism and the role of M-Y-W adduct in the catalase reaction. It is shown that O2 formation proceeds through a mechanism involving proton-coupled electron transfer (PCET). The M-Y-W cation radical adduct, which is close to the heme, His112 and the HOO. radical intermediate, acts as an electron sink during the PCET process. The present study also highlights the structural differences and functional similarities between KatGs and monofunctional catalases. PMID- 29462510 TI - Dioxygen Sensitivity of [Fe]-Hydrogenase in the Presence of Reducing Substrates. AB - Mono-iron hydrogenase ([Fe]-hydrogenase) reversibly catalyzes the transfer of a hydride ion from H2 to methenyltetrahydromethanopterin (methenyl-H4 MPT+ ) to form methylene-H4 MPT. Its iron guanylylpyridinol (FeGP) cofactor plays a key role in H2 activation. Evidence is presented for O2 sensitivity of [Fe] hydrogenase under turnover conditions in the presence of reducing substrates, methylene-H4 MPT or methenyl-H4 MPT+ /H2 . Only then, H2 O2 is generated, which decomposes the FeGP cofactor; as demonstrated by spectroscopic analyses and the crystal structure of the deactivated enzyme. O2 reduction to H2 O2 requires a reductant, which can be a catalytic intermediate transiently formed during the [Fe]-hydrogenase reaction. The most probable candidate is an iron hydride species; its presence has already been predicted by theoretical studies of the catalytic reaction. The findings support predictions because the same type of reduction reaction is described for ruthenium hydride complexes that hydrogenate polar compounds.

AB - OBJECTIVE: To examine the associations of worry about affording care and reporting financial difficulties with benefit finding in long-term cancer survivors. METHODS: Long-term survivors of cancer (n = 547) in 3 integrated health care delivery systems completed the Medical Expenditure Panel Survey Cancer Survivorship Supplement. The relationship between benefit finding (becoming a stronger person, coping better, and making positive changes) and the potentially interacting factors of worry about affording care and financial difficulties was examined using multivariate logistic regression models. RESULTS: Of the total sample, 20% reported worry and 15% reported financial difficulty. Among those who reported no worry, financial difficulty was positively associated with becoming a stronger person (odds ratio [OR] = 2.89, 95% CI: 1.07, 7.80). Coping better was not associated with worry, financial difficulties, or the interaction of the two. Among those with no financial difficulty, worry was positively associated with making positive changes (OR = 2.64, 95% CI: 1.41, 4.96), and among those reporting no worry, financial difficulty had a non significant positive association with making positive changes (OR = 1.98, 95% CI: 0.91, 4.31). Among those reporting worry, having financial difficulties was associated with lower odds of making positive changes (OR = 0.32, 95% CI: 0.13, 0.78). CONCLUSIONS: Our results suggest a complex relationship between financial difficulty, worry, and benefit finding. The combination of worry about affording care and financial difficulty needs to be addressed and further studied among cancer survivors, as the presence of both, but not alone, was negatively associated with making positive changes, an aspect of benefit finding.

AB - To investigate whether 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitor (statin) use is associated with an increased risk of diabetes mellitus and hyperglycemia, we performed a nested case-control study using a postmarketing surveillance database in Japan. The database cohort included 26,849 cases of statin use and 5308 cases of other lipid-lowering drug use in patients with hyperlipidemia. Participants received at least 1 type of statin, had a clear medication history of statin use, and had no complications of diabetes mellitus. Cases were defined as onset of diabetes mellitus or hyperglycemia during statin intake. For each case, 20 controls were randomly selected and matched by time point. The factors associated with an increased risk of diabetes mellitus and hyperglycemia during statin intake examined included sex, age, body mass index, statin use duration, complications, concomitant medication, and clinical laboratory tests. Statin-associated diabetes mellitus or hyperglycemia was identified based on abnormal elevation of blood glucose concentrations beyond the reference range. A total of 19,868 patients met the inclusion criteria, of whom 24 were patients in the case group. Two complicating factors, fatty liver (adjusted odds ratio 16.10) and hyperuricemia (adjusted odds ratio 28.96), were extracted for onset of diabetes mellitus or hyperglycemia. Nonalcoholic fatty liver was associated with diabetes mellitus, obesity, and insulin resistance, and hyperuricemia was associated with lifestyle. This study suggested that the onset of diabetes mellitus or hyperglycemia might be increased with statin use in patients with complications of fatty liver and hyperuricemia.

AB - BACKGROUND - Globally, human resources for health are being optimized to address the increasing health burden and concomitant increased demands on health professionals. These demands are even more exacting in Sub-SaharanAfrica considering the shortage of health care workers, especially physicians. The noteworthy efforts at deploying task-shifting to address this situation not withstanding, the situation also signals the need to re-define the objectives of medical instruction to ensure effective and contemporary medical practice in a mostly physician-led health workforce across the sub-continent. In this regard, medical and dental graduates must be educated to perform certain minimum essential professional duties competently. Essential Professional Duties are locally relevant professional activities of international standard that represent identifiable outcomes against which the effectiveness of physicians in a specific community can be measured to ensure social accountability. PROCEDURE AND PRODUCT The Association of Medical Schools of Africa has developed the 'Essential Professional Duties for sub-Saharan medical and dental graduates' to ensure these physicians provide safe and effective contemporary medical/dental practice on the sub-continent. The duties have been grouped into those required for basic patient care, basic administrative skills, basic emergency care, communication, inter professional relationships, self-directed learning and social responsibilities. Their relevance and suitability have been evaluated prior to their adoption by the Association. CONCLUSION; These Essential Physician Duties have been developed to serve as targets for health professionals training instruments and thus give direction to health system strategies. It is hoped that they will be adopted by medical and dental schools across sub-,. Saharan Africa. PMID- 29462527 TI - Dealing with diabetes-specific emotional distress: A cross-sectional survey of physical activity option. AB - BACKGROUND: Diabetes-specific emotional distress is common among people with type 2 diabetes due to the complexities associated with care and maintenance of wellness among the patients. Unlike the focus on glycaemic control, literature appears unavailable about how physical activity may help in the control of diabetes-specific emotional distress. This study was conducted to investigate the link between diabetes- specific emotional distress and physical activity. METHODOLOGY: Type 2 diabetes patients (n = 206) were enrolled into this study from two major health care facilities in Ibadan, Southwestern Nigeria. Physical activity was assessed using the International Physical Activity Questionnaire while diabetes-specific emotional distress was assessed using the Problem Areas in Diabetes Questionnaire. Data were analysed using descriptive and inferential statistics at +/- 0.05. RESULTS: The participants' mean age was 58.6 12.7 years with 109 (52.9%) reporting low physical activity levels and 182 (88.3%) reporting varying degrees of diabetes- specific emotional distress. Compared to participants with low physical activity, those who reported moderate-to- vigorous physical activity reported a reduced risk of diabetes-specific emotional distress (OR = 0.53; 95% CI = 0.26-0.82). Age, sex and level of education were not associated with the distress. CONCLUSIONS: A substantial proportion of patients with type 2 diabetes reported low physical activity levels and much more reported diabetes-specific emotional distress. Those who reported moderate-to-vigorous physical activity reported a significantly lower risk of diabetes-specific emotional distress. Reduction in. the risk of diabetes-specific emotional distress may be yet another strong point in advocacy for physical activity among patients with type 2 diabetes.

AB - BACKGROUND: The effects of maternal exposure to glucocorticoids during gestation on various organs in the offspring have been reported in literature. There is paucity of information on the effects of maternal glucocorticoids treatment during lactation on organ functions in the offspring. The present study was designed to investigate the changes in kidney function and oxidative stress biomarkers in offspring of dams treated with dexamethasone during lactation in Wistar rats METHODS: Twenty pregnant rats (180-200g) were divided into 4 groups (n=5). Group I was administered 0.02ml/100g/day of normal saline (subcutaneously, s.c) at lactation days 1-21 (control). Groups 2,3, and 4 were administered 100 MU/kg/day dexamethasone (Dex) (s.c) at lactation days 1-7 (Dexl-7),1-14(Dexl-14), and 1-21(Dexl-21) respectively. Evaluation of serum creatinine, urea and markers of oxidative stress in the kidney and histopathology of the kidney were carried out at 12 weeks of postnatal life. RESULTS: Serum creatinine and urea levels were. significantly (p<0.05) higher in the Dexl-7, DexI-14and Dexl-21 when compared with the control. Kidney MDA level was also significantly (p1087.0 IU/ml). She improved after rehydration, insulin therapy and antithyroid drugs. CONCLUSION: Coexisting autoimmune diseases may present in patients with Down's syndrome. We advocate for routine screening for diabetes and thyroid dysfunction in ersons with Down's syndrome.

AB - Treehoppers are known for their substrate-borne communication and some of them also for their subsocial behavior. Following a more general study of the natural history and substrate-borne signal repertoire of the treehopper Ennya chrysura, the objective of this paper was to explore in greater depth the signals and other behaviors associated specifically to egg-guarding. Theese were studied both in natural and laboratory conditions between July, 2000 and March, 2004. The spacial distribution of egg guarding females was studied in the natural population; recording equipment and playback experiments were used in the laboratory and then analyzed digitally. Under natural conditions (San Antonio de Escazu, Costa Rica), female E. chrysura guard their egg masses and egg-guarding was associated with lower parasitism of the eggs from the wasps Gonatocerus anomocerus and Schizophragma sp. (Mymaridae). Females tended to place their eggs close to other egg-guarding females and they produced substrate-borne vibrations when disturbed. An aggregated pattern under natural conditions was confirmed by calculating dispersion indices from egg-clutch data obtained from 66 leaves in the field. The disturbance signal was characterized from laboratory recordings of substrate borne vibrations of 10 egg-guarding females. Experiments conducted in the laboratory with 18 egg-guarding females showed that those which were previously exposed to the disturbance signal of another female moved slightly or vibrated more during playbacks and that they reacted more quickly and exhibited more deffensive behaviors in response to a tactile stimulus. The signals produced while defending against egg parasites may therefore function as an alarm and favor aggregating behavior of egg-guarding females.

AB - Bacterial resistance is a growing health problem worldwide that has serious economic and social impacts, compromising public health, and the therapeutic action of current antibiotics. Therefore, the search for new compounds with antimicrobial properties is relevant in modern studies, particularly against bacteria of clinical interest. In the present study, in vitro antibacterial activity of the ethanol extract and essential oil of Curcuma longa (Zingiberaceae) was evaluated against nosocomial bacteria, using the microdilution method. Escherichia coli strains, Pseudomonas aeruginosa, Klebsiella pneumoniae, Proteus sp. were used, Salmonella sp. and Bacillus sp., isolated from nosocomial infections in a hospital in the city of Monteria and reference strains of S. aureus ATCC 43300, S. aureus ATCC 29213, S. aureus ATCC 25923, P. aeruginosa ATCC 27853, E. coli ATCC 25922 and K. pneumonia ATCC 700603. The ethanol extract antibacterial profile was more efficient at higher concentrations (1 000 ppm), obtaining significant percentages of reduction of more than 50 % against K. pneumoniae ATCC 700603 and a clinical isolate of E. coli; while compared to Bacillus clinical isolate, was more active than the essential oil. For the rest of microorganisms, the reduction percentages obtained at a concentration of 1 000 ppm varied between 17 and 42 % with ethanolic extract, and 8 to 43 % with essential oil. At concentrations of 100 and 500 ppm antibacterial activity of the extracts was lower. The results indicated that the ethanolic extract and essential oil of C. longa rhizomes have active compounds with antibacterial properties that could be used in future research as a therapeutic alternative for the treatment of infections caused by nosocomial pathogens.

This article analyzes document type, language, countries, institutions, citations and for the first time article lifespan, from 1976 through 2014. We analyzed 3 978 documents from the Science Citation Index Expanded. Articles comprised 88 % of the total production and had 3.7 citations on average, lower than reviews. Spanish and English articles were nearly equal in numbers and citation for English articles was only slightly higher. Costa Rica, Mexico, and the USA are the countries with more articles, and the leading institutions were Universidad de Costa Rica, Universidad Nacional, Universidad Nacional Autonoma de Mexico and Universidad de Oriente (Venezuela). The citation lifespan of articles is long, around 37 years. It is not surprising that Costa Rica, Mexico, and Venezuela lead in productivity and cooperation, because they are mostly covered by tropical ecosystems and share a common culture and a tradition of scientific cooperation. The same applies to the leading institutions, which are among the largest Spanish language universities in the neotropical region. American output can be explained by the regional presence of the Smithsonian Tropical Research Institute and the Organization for Tropical Studies. Tropical research does not have the rapid change typical of medical research, and for this reason, the impact factor misses most of citations for the Revista, which are made after the two-year window used by the Web of Science. This issue is especially damaging for the Revista because most journals that deal with tropical biology are never checked when citations are counted for by the Science Citation Index.

AB - The leishmaniasis is a complex disease system, caused by the protozoan parasite Leishmania and transmitted to humans by the vector Lutzomyia spp. Since it is listed as a neglected disease according to the World Health Organization, the aim of this study was to determine the current and future niche of cutaneous and visceral leishmaniasis in the Neotropical region. We built the ecological niche model (ENM) of cutaneous (N= 2 910 occurrences) and visceral (N= 851 occurrences) leishmaniasis using MaxEnt algorithm. Nine bioclimatic variables (BIO1, BIO4, BIO5, BIO6, BIO7, BIO12, BIO13, BIO14, BIO15 (downloaded from the Worldclim) and disease occurrences data were used for the construction of ENM for three periods (current, 2050 and 2070) and four climate change scenarios (RCP 2.6, 4.5, 6.0 y 8.5). We analyzed the number of pixels occupied, identity niche, modified niche (stable, loss, and gain) and seasonality. Our analyses indicated the expansion for cutaneous leishmaniasis (CL), a comparison for visceral leishmaniasis (VL). We rejected the null hypothesis of niche identity between CL and VL with Hellinger's index = 0.91 (0.92-0.98) and Schoener's Index = 0.67 (0.85-1.00) but with an overlap niche of 56.3 %. The differences between the two leishmaniasis types were detected in relation to RCP scenarios and niche shifts (area gained / loss). Seasonality was more important for CL. We provided a current picture of CL and VL distributions and the predicted distributional changes associated to different climate change scenarios for the Neotropical region. We can anticipate that increasing range is likely although it will depend locally on the future trends in weather seasonality.

AB - Thygater aethiops is a native bee that can be found in parks and gardens in diverse urban areas such as those in the city of Bogota (Colombia). However, little is known about its biology as well as ecological adaptations to urban areas. This study aimed to describe the seasonal cycle and daily foraging activities of T. aethiops, as well as identify the pollen resources used by this bee over a year in a population nesting in an aggregation in the "Parque Nacional Enrique Olaya Herrera" in Bogota. Changes in the nest activity were monitored weekly by counting the number of active nests in the aggregation between December/2012 and February/2014. To determine the daily foraging activity, the numbers of bees entering their nests over a period of 10 minutes every hour between 8:00 and 14:00 h were recorded. Females with pollen loads entering to their nest were captured weekly, between September/2012 and August/2013, and their pollen loads analyzed. Three nesting peaks occurred after the precipitation peaks, but the number of active nests was not correlated with precipitation. The nesting activities stopped in a large number of the active nests (20-50 % of nests) after an anthropic disturbance was registered in the nesting area. Bees forage for nectar and pollen between 8:00 and 14:00 h, with a peak at 10:00 h. Daily foraging activity changed during the study period due to anthropic disturbance. There was not a significant relationship between air temperature and the number of females entering their nests. Foraging activities did not change between the dry and rainy seasons. A total of 26 pollen types were found in 169 pollen loads. Ulex europaeus (Fabaceae) and Solanum laxum (Solanaceae) were the most abundant plants represented on the pollen load across the study period. According to these results, T. aethiops would be considered a mesolectic species. The ability of T. aethiops to use different pollen resources both native and exotic, as well as to presumably recover its population after disturbances, are characteristics that may have allowed this bee to adapt to urban environments. Knowledge on the floral resources as well as other biological features of this bee species is important to promote its conservation in urban areas.

AB - The brown swimming crab (Callinectes bellicosus) is an economically important species in the Gulf of California, and its fishing activity, held in Sonora from 1986, has been affected by a 20-year declining trend in its biomass. With the aim to understand the possible reasons of this species population changes along time, we estimated population growth rate (r) and sex ratio of C. bellicosus, and combined them with three parameters describing its habitat: sea temperature, wetland extension and habitat size in four areas along the coast of Sonora. For this, monthly mean sex ratio was estimated from crabs samples obtained from commercial catches during 1998-2002 and 2012; mean sea surface temperature for the spawning period (May-August) were derived from remote sensors for the same years; while wetland coverages were obtained from published reports, and habitat size was estimated as the fishing surface. For each area, r was estimated using a method developed for limited data situations using commercial landings (t) from 1986-2013. With data from the four areas, simple and multiple linear regression models were developed to ascertain theoretical sensitivities of r to variations in sex ratio and environmental parameters. A total of 24 556 crabs were sampled; males dominated (68.8 %) over females during the study period and in all areas; a cluster analysis identified two groups according to sex ratio: a Northern group with zones 1 and 2, and a Southern group with zones 3 and 4. r values were different in all zones (P<0.001) as was sex ratio (P=0.037); no differences in temperature were identified within the study years (P>0.995). Both the estimated data and sensitivity analyses suggest the existence of a direct and positive dependence of r on the proportion of female crabs and wetland size. We hypothesize that excess fishing of females caused the declining biomass trend of the brown swimming crab in Sonora, and concluded on the convenience of implementing harvest refugia inside coastal wetlands to protect females during the spawning season.

The present work describes the micro morphological characteristics of leaflets from adult plants of B. gasipaes, thornless variety Diamantes-10, collected in the Diamantes Experimental Station in Guapiles, Costa Rica. We collected 25 leaflets and analyses were performed with a combination of microscopy techniques: light microscopy, scanning electron microscopy and transmission electron microscopy to study their structure. Our results showed that leaflets have abundant epicuticular wax on adaxial and abaxial surfaces. Analyses from the epidermis indicated that it is composed of isodiametric cells, and it is also evident that hypodermis cells have rectangular shape and are larger than the other epidermal cells. We observed stomata on both surfaces, but they were more abundant in the abaxial surface. On the other hand, the epidermis showed the presence of trichomes with three different morphologies. In the parenchyma, cells are large and not well defined, and we observed the presence of astroesclereids, and compact groups of fiber bundles between parenchyma cells. The central vein has several vascular bundles, arranged in a continuous manner, and they are surrounded by sclerotic tissue; some of these fibers presented live protoplasts. All minor veins showed the same anatomy as the central vein. In these veins, the vessel elements of protoxylem and metaxylem showed scalariform ornaments on their walls. Phloem is located towards the adaxial surface of the vein and we observed sieve and companion cells surrounded by fibers and parenchyma cells. The companion cells presented branched plasmodesmata attached to a sieve element, and in these elements we found protein bodies called P protein. The main anatomical difference in the leaflets of the var. Diamantes-10, compared to the other varieties of B. gasipaes K, is the lack of thorns; the other morphological features seem to be conserved. PMID- 29462544 TI - Population dynamics and reproductive biology of Barilius bendelisis (Cyprinidae: Cypriniformes) from river Gaula of Central Indian Himalaya. AB - The Indian hill trout cyprinid, Barilius bendelisis is a member of family Cyprinidae that dwells in shallow, cold, and clear water. In this study, growth parameters and reproductive biology of Indian hill trout, Barilius bendelisis from river Gaula, Central Himalaya region, India, were studied. The length frequency data were grouped sex wise and were analyzed to determine the growth and mortality parameters using the computer software programme, FAO-ICLARM Stock Assessment Tool (FISAT II). Altogether, 501 individuals were collected from river Gaula (November 2013-October 2014) and were preserved in formalin for further analysis. The results showed that the female outnumbered the male population. The minimum GSI of females was observed in the month of October (4.93 +/- 0.26) and for males in the month of June and July (0.093 +/- 0.12), whereas, the maximum value was in the month of April for both females (13.47 +/- 0.52) and males (1.21 +/- 0.12). Fluctuation in GSI values had a bimodal pattern showing two peaks during March-May and August-September in both the sexes, indicating the common spawning period of fish. The slope of regression showed the negative allometric growth for both males and females (b= 2.65 for male and b= 2.5 for female). A significant relationship between length and weight was observed in the present study (p < 0.05). The ELEFAN-I estimated Linfinity and K of the von Bertalanffy growth factor for males (17.33 cm and 0.310 per year), females (17.33 cm and 0.3 per year) and pooled sexes (17.33 cm and 0.240 per year). The results indicated that Barilius bendelisis is a small sized fish having negative allometric growth that spawns twice a year. Thus, the present study on biological traits represents the baseline information for effective production, conservation and restoration planning.

AB - Utricularia is a genus of carnivorous plants that capture a wide range of aquatic organisms. Most of these plants grow in environments with nutrients deficiency and have the ability to change the conditions of their microenvironment. The aim of this research was to study the selectivity in the zooplankton capture by Utricularia foliosa in the Cienaga de Paredes. Our study was undertaken between February and November, 2014. We tried to determine if there is selection in the plant's food resources by the Czekanowski's index, and the selection degree by the Savage and Ivlev's indexes. Additionally, we studied the possible relationship between the patterns of zooplankton capture and selection, with physicochemical variables in the swamp. The Czekanowski's index showed a food selection in plant resources throughout the flood pulse, with values between 0.28 and 0.41. We also found a significant positive selection with Savage's index for Lecane sp., Alona sp., Ceriodaphnia sp., and Bosmina sp. (p < 0.05); similar results were obtained with Ivlev's index. The intensity in the selection of each captured genus varied significantly between hydrological periods and between high and low water levels in the swamp. It was possible to identify some changes in the ammonia and nitrate concentration and some variability in the electric conductivity of the swamp, which influenced the captures made by U. foliosa. This is the first paper that allows an approach to understand the selection of food resources for the species, using a selectivity index, and one of the few for the genus. PMID- 29462547 TI - Brachiopods, sipunculans, enteropneusts and metals from two estuarine tidal flats, Pacific, Costa Rica. AB - Reports on the abundances and on metal concentrations in intertidal estuarine invertebrates from theEastern Tropical Pacific are rare. Thus, the objectives of this report are to make accessible data on the abundances(1984-1987, 49 dates; 2013, 12 dates) of sipunculans, brachiopods and hemichordates from a sand-mud flat; and ontrace metals (1996, 2000) and abundances (2015, 3 dates) of sipunculans and brachiopods at a sand flat in the Gulfof Nicoya estuary (10o N 85o W). Cores (17.7 cm2) were collected at the sand-mud flat, and quadrats (0.2 m2) atthe sand flat. The flats contrasted in their sand (65 % vs 90 %) and silt+clay (31.5 % vs 5.6 %) contents. At thesand-mud flat (1984-87: 1.83 m2) the sipunculans were represented by 13 individuals, the brachiopods by 129 andthe acorn worms by 185, with estimated maximum densities of: 5.7, 29, and 40 ind./m2, respectively. Trace metal(Fe, Mn, Ni, Cr, Cd, Zn, and Pb) analysis (Atomic Absorption Spectrometry) were conducted in specimens ofSipunculus nudus (Sipuncula) and Glottidia audebarti (Brachiopoda). Maximum mean concentrations in S. nuduswere: For non-depurated worms, Fe (16.0 mg/g dw) > Mn (165 MUg/g dw) > Zn (81 MUg/g dw) > Cu (26 MUg/g dw)> Cr (11 MUg/g dw) > Ni (10.4 MUg/g dw) > Pb (9.3 MUg/g dw) > Cd (1.2 MUg/g dw). For 72 hour depurated worms:Fe (5.0 mg/g dw) > Mn (61 MUg/g dw) > Zn (39 MUg/g dw) > Cu (24 MUg/g dw) > Ni (8.4 MUg/g dw) > Pb (2.7 MUg/gdw) > Cd (0.62 MUg/g dw). For G. audebarti: Fe (1.6 mg/g dw-soft parts) > Zn (123.5 MUg/g dw-soft parts) > Cu(31.4 MUg/g dw-pedicles) > Pb (21.0 MUg/g dw shells) > Cd (5.2 MUg/g dw-soft parts) > Cr (4.7 MUg/g dw-shells). Forsediments; Fe (46 mg/g dw) > Mn (41.3 MUg/g dw) > Zn (63 MUg/g dw) > Cu (36.2 MUg/g dw) > Cr (31.5 MUg/g dw)> Pb (21.1 MUg/g dw) > Ni (16.1 MUg/g dw) > Cd (1.1 MUg/g dw). These concentrations were expected for a nonindustrializedestuary. At the sand flat (Area sampled: 10.6 m2 ) 76 individuals of G. audebarti, 112 of G. albida,and 366 of S. nudus were collected in 2015, with estimated maximum densities of: 7.1, 10.5, and 31 ind./m2,respectively. Densities of G. audebarti and G. albida were relatively low, while those of S. nudus were relativelyhigh when compared with other reports. The shell lenght of G. audebarti ranged from 9.0 mm to 38.0 mm and from6.0 mm to 29.0 mm for G. albida. These ranges were within those found for these lingulides elsewhere. The meanlength of S. nudus was 41 mm and the maximum weight was 1.6 g, which are small. No brachiopods were found atthe sand-mud flat in 2013, nor enteropneusts at the sand flat in 2015. G. audebarti had a relatively stable presence,while G. albida almost vanished from the samples at the end of 2015. The spatial distributions of the three invertebrateswere found aggregated at both intertidal flats. Strong ENSO warming events during 1983 and 2015, and redtides in 1985 may have influenced the abundances. PMID- 29462548 TI - Understory bat roosts, availability and occupation patterns in a Neotropical rainforest of Costa Rica. AB - The strong link between bats and their roosts is widely recognized as being particularly significant. Despite this, roosting ecology of bats is poorly understood and much of the basic information is still unknown. In this study, we investigated the availability and occupation patterns of four roost types (trees, caves, termite nests and tents) used by bats at Tirimbina Biological Reserve (TBR), Costa Rica. To accomplish our aim, we systematically surveyed both sides of established trails and transects, looking for understory roosts. Potential roosts were examined for bat presence in order to establish occupation. Roost availability and density were estimated using traveled distances (km) and inspected area (10 m for trees/caves and 15 m for tents/termite nests) of each trail or transect sampled. For the tent roosts, data on taxonomic information of plant modified, type of architecture, condition and construction achievement were also recorded. The area surveyed represented 45.4 % of the total area of the TBR (345 ha). Tents were the most common roost (56.6 % of all roosts, N = 223), followed by trees (24.4 %, N = 96), termite nests (18.8 %, N = 74) and caves (0.2 %, N = 1). We detected only 27 roosts occupied by bats (6.8 % of all roosts, 0.17 occupied roosts/ha). Caves showed the highest occupation rate (100 %, N = 1), followed by trees (17.7 %, N = 17), tents (3.6 %, N = 8) and termite nests (1.3 %, N = 1). We found the roosts for 10 species, representing 33.9 % of the bat fauna documented at the reserve (62 species). Density of roosts per bat species varied between 0.017-0.138 roosts/ha. Phyllostomidae was the best-represented family with Micronycteris microtis representing the most common species encountered. Four distinct tent architectures were documented. Bifid architecture was the most common (133 tents), followed by Conical (47 tents), Apical (27 tents) and Inverted Boat (16 tents). Most of the tents found were healthy (76.7 %, N = 171) and totally constructed (88.8 %, N = 198). Our study demonstrated that occupied bat roosts are difficult to find in the forest. When compared to the roost availability, the low occupation rates suggested that, at least in our study area, roosts might not be a limiting resource. Nevertheless, to confirm this hypothesis, information about fidelity and selection process of the species is fundamental for understanding to what extent these roosts meet the requirements to be inhabited or modified. Worldwide conservation efforts on bats should focus on understanding roosting ecology, especially due to anthropogenic pressures that are continuously reducing the availability of roosts, which undoubtedly contributes to the risk of extinction for specialized and sensitive species.

AB - The renin-angiotensin system (RAS) is an important regulator of cirrhosis and portal hypertension. As hepatic fibrosis progresses, levels of the RAS components angiotensin (Ang) II, Ang-(1-7), angiotensin-converting enzyme (ACE), and Ang II type 1 receptor (AT1R) are increased. The primary effector Ang II regulates vasoconstriction, sodium homoeostasis, fibrosis, cell proliferation, and inflammation in various diseases, including liver cirrhosis, through the ACE/Ang II/AT1R axis in the classical RAS. The ACE2/Ang-(1-7)/Mas receptor and ACE2/Ang (1-9)/AT2R axes make up the alternative RAS and promote vasodilation, antigrowth, proapoptotic, and anti-inflammatory effects; thus, countering the effects of the classical RAS axis to reduce hepatic fibrogenesis and portal hypertension. Patients with portal hypertension have been treated with RAS antagonists such as ACE inhibitors, Ang receptor blockers, and aldosterone antagonists, with very promising hemodynamic results. In this review, we examine the RAS, its roles in hepatic fibrosis and portal hypertension, and current therapeutic approaches based on the use of RAS antagonists in patients with portal hypertension.

AB - Condition indices reflect the performance of an organism in their environment, as well as theirsomatic condition, nutritional value, commercial importance, the ecological role and fattening periods. In thisstudy, different physiological indices were evaluated in order to know the Arca zebra population status, and tosuggest operation and sustainability strategies for this resource use and consumption. A total of 240 samples (82males and 158 females) were collected between July 2010 and July 2011, from the Chacopata bank site. Bivalvebiometric measurements were made monthly and considered: total shell length, height and width; besides, softtissues were dehydrated to obtain total dry mass. Different condition indices were analyzed based on the bodymass, or on the combination of mass and shell length: gonadal index, muscle index, meat yield, the fresh mass ofsoft tissue in relation to the total length, and dry mass of soft tissue relative to the total length. We found the modelwith positive allometric growth between the length-total dry mass. The gonadal weight exerted a marked influenceon the condition index, gonadosomatic index and meat yield. Increases in soft tissue mass were proportionalto the dimensions of the shell. The index contrasts fresh mass of soft tissue in relation to the total length, as a toolthat would allow fishers to estimate the population dynamics of A. zebra, and to practice a sustainable fisheryover time, while keeping the extraction canons. PMID- 29462551 TI - Copper-Coupled Electron Transfer in Colloidal Plasmonic Copper-Sulfide Nanocrystals Probed by in Situ Spectroelectrochemistry. AB - Copper-sulfide nanocrystals can accommodate considerable densities of delocalized valence-band holes, introducing localized surface plasmon resonances (LSPRs) attractive for infrared plasmonic applications. Chemical control over nanocrystal shape, composition, and charge-carrier densities further broadens their scope of potential properties and applications. Although a great deal of control over LSPRs in these materials has been demonstrated, structural complexities have inhibited detailed descriptions of the microscopic chemical processes that transform them from nearly intrinsic to degenerately doped semiconductors. A comprehensive understanding of these transformations will facilitate use of these materials in emerging technologies. Here, we apply spectroelectrochemical potentiometry as a quantitative in situ probe of copper-sulfide nanocrystal Fermi level energies ( EF) during redox reactions that switch their LSPR bands on and off. We demonstrate spectroscopically indistinguishable LSPR bands in low chalcocite copper-sulfide nanocrystals with and without lattice cation vacancies and show that cation vacancies are much more effective than surface anions at stabilizing excess free carriers. The appearance of the LSPR band, the shift in EF, and the change in crystal structure upon nanocrystal oxidation are all fully reversible upon addition of outer-sphere reductants. These measurements further allow quantitative comparison of the coupled and stepwise oxidation/cation vacancy-formation reactions associated with LSPRs in copper-sulfide nanocrystals, highlighting fundamental thermodynamic considerations relevant to technologies that rely on reversible or low-driving-force plasmon generation in semiconductor nanostructures. PMID- 29462552 TI - Revealing Abrupt and Spontaneous Ruptures of Protein Native Structure under picoNewton Compressive Force Manipulation. AB - Manipulating protein conformations for exploring protein structure-function relationship has shown great promise. Although protein conformational changes under pulling force manipulation have been extensively studied, protein conformation changes under a compressive force have not been explored quantitatively. The latter is even more biologically significant and relevant in revealing protein functions in living cells associated with protein crowdedness, distribution fluctuations, and cell osmotic stress. Here we report our experimental observations on abrupt ruptures of protein native structures under compressive force, demonstrated and studied by single-molecule AFM-FRET spectroscopic nanoscopy. Our results show that the protein ruptures are abrupt and spontaneous events occurred when the compressive force reaches a threshold of 12-75 pN, a force amplitude accessible from thermal fluctuations in a living cell. The abrupt ruptures are sensitive to local environment, likely a general and important pathway of protein unfolding in living cells. PMID- 29462550 TI - Three-dimensional Architecture Enabled by Strained Two-dimensional Material Heterojunction. AB - Engineering the structure of materials endows them with novel physical properties across a wide range of length scales. With high in-plane stiffness and strength, but low flexural rigidity, two-dimensional (2D) materials are excellent building blocks for nanostructure engineering. They can be easily bent and folded to build three-dimensional (3D) architectures. Taking advantage of the large lattice mismatch between the constituents, we demonstrate a 3D heterogeneous architecture combining a basal Bi2Se3 nanoplate and wavelike Bi2Te3 edges buckling up and down forming periodic ripples. Unlike 2D heterostructures directly grown on substrates, the solution-based synthesis allows the heterostructures to be free from substrate influence during the formation process. The balance between bending and in-plane strain energies gives rise to controllable rippling of the material. Our experimental results show clear evidence that the wavelengths and amplitudes of the ripples are dependent on both the widths and thicknesses of the rippled material, matching well with continuum mechanics analysis. The rippled Bi2Se3/Bi2Te3 heterojunction broadens the horizon for the application of 2D materials heterojunction and the design and fabrication of 3D architectures based on them, which could provide a platform to enable nanoscale structure generation and associated photonic/electronic properties manipulation for optoelectronic and electromechanic applications. PMID- 29462553 TI - Light-Activated Core-Shell Nanoparticles for Spatiotemporally Specific Treatment of Metastatic Triple-Negative Breast Cancer. AB - Triple-negative breast cancer (TNBC) tumors are heterogeneous, with mesenchymal like cells at their core and fast proliferating cells on the periphery. It is desirable and beneficial to treat TNBC cells of different phenotypes with the most appropriate drugs. Here, we report a 78 nm, chlorin e6-, docetaxel-, and anti-Twist siRNA-containing polymeric nanoparticle (CDTN) with spatiotemporally specific activity when irradiated by light. Under conditions mimicking superficial tumor tissue with sufficient light input, TNBC cells are mainly killed by the photodynamic therapy (PDT) function of CDTNs. In contrast, under conditions mimicking deep tumor tissue with weak light input, PDT potentiates chemotherapy (CT) and gene therapy (GT) by facilitating the endolysosomal escape of CDTNs. Compared with free drugs, CDTNs improve the intratumoral exposure of docetaxel and anti-Twist siRNA by 2.5- and 2-fold, respectively. When combined with laser irradiation applied at the time of maximal intratumoral accumulation, the CDTNs significantly inhibit the growth of primary tumors and their lung metastasis (both >80%) by killing the peripheral cells, mainly through PDT and prohibiting the growth and metastasis of deep cells through PDT as enhanced CT and GT. On the contrary, dual-modality nanomedicine lacking CT, GT, or PDT showed fast primary tumor growth, poor metastasis control, or both, respectively. This study reveals the spatiotemporally specific mechanism of CDTNs in treating metastatic TNBC and highlights the importance of combined therapy in treating TNBC. PMID- 29462555 TI - When Al-Doped Cobalt Sulfide Nanosheets Meet Nickel Nanotube Arrays: A Highly Efficient and Stable Cathode for Asymmetric Supercapacitors. AB - Although cobalt sulfide is a promising electrode material for supercapacitors, its wide application is limited by relative poor electrochemical performance, low electrical conductivity, and inefficient nanostructure. Here, we demonstrated that the electrochemical activity of cobalt sulfide could be significantly improved by Al doping. We designed and fabricated hierarchical core-branch Al doped cobalt sulfide nanosheets anchored on Ni nanotube arrays combined with carbon cloth (denoted as CC/H-Ni@Al-Co-S) as an excellent self-standing cathode for asymmetric supercapacitors (ASCs). The combination of structural and compositional advantages endows the CC/H-Ni@Al-Co-S electrode with superior electrochemical performance with high specific capacitance (1830 F g-1/2434 F g-1 at 5 mV s-1/1 A g-1) and excellent rate capability (57.2%/72.3% retention at 1000 mV s-1/100 A g-1). The corresponding all-solid-state ASCs with CC/H-Ni@Al-Co-S and multilayer graphene/CNT film as cathode and anode, respectively, achieve a high energy density up to 65.7 W h kg-1 as well as superb cycling stability (90.6% retention after 10 000 cycles). Moreover, the ASCs also exhibit good flexibility and stability under different bending conditions. This work provides a general, effective route to prepare high-performance electrode materials for flexible all-solid-state energy storage devices. PMID- 29462556 TI - WO3/Conducting Polymer Heterojunction Photoanodes for Efficient and Stable Photoelectrochemical Water Splitting. AB - An efficient and stable heterojunction photoanode for solar water oxidation was fabricated by hybridization of WO3 and conducting polymers (CPs). Organic/inorganic hybrid photoanodes were readily prepared by the electropolymerization of various CPs and the codeposition of tetraruthenium polyoxometalate (Ru4POM) water-oxidation catalysts (WOCs) on the surface of WO3. The deposition of CPs, especially polypyrrole (PPy) doped with Ru4POM (PPy:Ru4POM), resulted in a remarkably improved photoelectrochemical performance by the formation of a WO3/PPy p-n heterojunction and the incorporation of efficient Ru4POM WOCs. In addition, there was also a significant improvement in the photostability of the WO3-based photoanode after the deposition of the PPy:Ru4POM layer due to the suppression of the formation of hydrogen peroxide, which was responsible for corrosion. This study provides insight into the design and fabrication of novel photosynthetic and photocatalytic systems with excellent performance and stability through the hybridization of organic and inorganic materials. PMID- 29462557 TI - Honeydew Honeys: A Review on the Characterization and Authentication of Botanical and Geographical Origins. AB - The commercial interest in honeydew honeys (from the secretions of plants or the excretions of plant-sucking insects found on plants) is increasing because of their higher therapeutic properties compared with those of most blossom honeys (from nectar). However, honeydew honeys have been less studied than blossom honeys. In this work, studies carried out to characterize and authenticate honeydew honeys by their botanical and geographical origins have been reviewed. The identification of honey origins has been approached by two ways: by the analysis of chemical markers and by the development of analytical methodologies combined with multivariate analyses. Some compounds have been suggested as specific botanical markers of several honeydew honeys, such as quercitol and trans-oak lactone for oak honey, 2-aminoacetophenone and propylanisol for holm oak honey, and 1-chloro-octane and tridecane for pine honey. The presence of 3 carene and an unidentified compound in samples was proposed as a way discriminate between Greek and Turkish pine honeys. Chemometric analyses have been applied on chemical compositions and on physicochemical, microscopic, and spectral parameters and have proved to be valuable methods for authenticating honeydew honeys. Analytical methods based on spectral information are suitable for the routine control of honeydew-honey origins because they are fast and require easy sample preparations.

As personalized cancer treatments are gaining popularity, a need for more advanced imaging techniques has grown significantly. Nanoparticles are uniquely suited to fill this void, not only as imaging contrast agents but also as companion diagnostics. This review provides an overview of many ways nanoparticle imaging agents have contributed to cancer imaging, both preclinically and in the clinic, as well as charting future directions in companion diagnostics. We conclude that, while nanoparticle-based imaging agents are not without considerable scientific and developmental challenges, they enable enhanced imaging in nearly every modality, hold potential as in vivo companion diagnostics, and offer precise cancer treatment and maximize intervention efficacy. PMID- 29462558 TI - Molecular Imaging of Mesothelin-Expressing Ovarian Cancer with a Human and Mouse Cross-Reactive Nanobody. AB - Mesothelin is an epithelial marker highly expressed at the cell surface of cancer cells from diverse origins, including ovarian and pancreatic adenocarcinomas and mesotheliomas. Previously, we identified and characterized an antimesothelin nanobody (NbG3a) for in vitro diagnostic applications. The main goal of this research was to establish the potential of NbG3a as a molecular imaging agent. Site-specific biotinylated NbG3a (bNbG3a) was bound to streptavidin-conjugated reagents for in vitro and in vivo assays. Initially, we performed microscale thermophoresis to determine the binding affinity between bNbG3a and human ( Kd = 46 +/- 8 nM) or mouse ( Kd = 4.8 +/- 0.4 nM) mesothelin protein. The human and mouse cross-reactivity was confirmed by in vivo optical imaging using bNbG3a bound to fluorescent streptavidin. We also localized the binding site of nNbG3a on human mesothelin using overlapping peptide scan. NbG3a recognized an epitope within residues 21-65 of the mature membrane bound form of human mesothelin, which is part of the N-terminal region of mesothelin that is important for interactions between mesothelin on peritoneal cells and CA125 on tumor cells. Next, the bNbG3a in vivo half-life after intravenous injection in healthy mice was estimated by ELISA assay to be 5.3 +/- 1.3 min. In tumor-bearing animals, fluorescent bNbG3a accumulated in a subcutaneous ovarian xenograft (A1847) and in two syngeneic, orthotopic ovarian tumors (intraovary and intraperitoneal ID8) within an hour of intravenous injection that peaked by 4 h and persisted up to 48 h. MRI analysis of bNbG3a-targeted streptavidin-labeled iron oxides showed that the MRI signal intensity decreased 1 h after injection for a subcutaneous xenograft model of ovarian cancer for bNbG3a-labeled iron oxides compared to unlabeled iron oxides. The signal intensity differences continued up to the final time point at 24 h post injection. Finally, in vivo immunofluorescence 24 or 48 h after bNbG3a intravenous injection showed bNbG3a diffuse distribution of both xenograft and syngeneic ovarian tumors, with local areas of high concentration throughout A1847 human tumor. The data support the use of NbG3a for continued preclinical development and translation to human applications for cancers that overexpress mesothelin.

AB - Plastic debris is a major environmental concern, and to find effective ways to reuse polystyrene (PS) presents major challenges. Here, it is demonstrated that polystyrene foams impregnated with SnO2 are easily generated from plastic debris and can be applied to photocatalytic degradation of dyes. SnO2 nanoparticles were synthesized by a polymeric precursor method, yielding specific surface areas of 15 m2/g after heat treatment to 700 degrees C. Crystallinity, size, and shape of the SnO2 particles were assessed by X-ray diffraction (XRD) and transmission electron microscopy (TEM), demonstrating the preparation of crystalline spherical nanoparticles with sizes around 20 nm. When incorporated into PS foams, which were generated using a thermally induced phase separation (TIPS) process, the specific surface area increased to 48 m2/g. These PS/SnO2 nanofoams showed very good efficiency for photodegradation of rhodamine B, under UV irradiation, achieving up to 98.2% removal. In addition the PS/SnO2 nanofoams are shown to retain photocatalytic activity for up to five reuse cycles. PMID- 29462560 TI - Density Functional Theory and the Basis Set Truncation Problem with Correlation Consistent Basis Sets: Elephant in the Room or Mouse in the Closet? AB - Two recent papers in this journal called into question the suitability of the correlation consistent basis sets for density functional theory (DFT) calculations, because the sets were designed for correlated methods such as configuration interaction, perturbation theory, and coupled cluster theory. These papers focused on the ability of the correlation consistent and other basis sets to reproduce total energies, atomization energies, and dipole moments obtained from "quasi-exact" multiwavelet results. Undesirably large errors were observed for the correlation consistent basis sets. One of the papers argued that basis sets specifically optimized for DFT methods were "essential" for obtaining high accuracy. In this work we re-examined the performance of the correlation consistent basis sets by resolving problems with the previous calculations and by making more appropriate basis set choices for the alkali and alkaline-earth metals and second-row elements. When this is done, the statistical errors with respect to the benchmark values and with respect to DFT optimized basis sets are greatly reduced, especially in light of the relatively large intrinsic error of the underlying DFT method. When judged with respect to high-quality Feller Peterson-Dixon coupled cluster theory atomization energies, the PBE0 DFT method used in the previous studies exhibits a mean absolute deviation more than a factor of 50 larger than the quintuple zeta basis set truncation error. PMID- 29462561 TI - Impact of Edge Groups on the Hydration and Aggregation Properties of Graphene Oxide. AB - Molecular dynamics simulations were used to describe and quantify the role of edge groups on the hydrating properties of graphene oxide (GO). For this, six different oxygen concentrations were investigated, and in four of them, carboxyl groups were present. Structural analysis indicates a greater probability for the water solvation around the GO edges in detriment of the region of its basal plane, while hydrogen bonding analyses indicates that edge groups are very expressive, participating in about 60% of the total number of bonds. The impact of this bond network formed by edge groups is rationalized in energetic and thermodynamic terms. The resulting hydrophilicity observed, as expected, is of electrostatic origin and has a larger contribution from the edge groups that varies from 22 to 57% depending on the concentration. Hydration free energy and potential of mean force calculations support these findings. It was observed that the edge groups contribute up to 51% of the total hydration-free energy and that the PMF indicates the tendency for spontaneous aggregation at all investigated concentrations, being lower the higher the concentration of oxygen. PMID- 29462562 TI - Exosome-Mediated Ultra-Effective Direct Conversion of Human Fibroblasts into Neural Progenitor-like Cells. AB - Exosomes, naturally secreted nanoparticles, have been introduced as vehicles for horizontal transfer of genetic material. We induced autologous exosomes containing a cocktail of reprogramming factors ("reprosomes") to convert fibroblasts into neural progenitor cells (NPCs). The fibroblasts were treated with ultrasound and subsequently cultured in neural stem cell medium for 1 day to induce the release of reprosomes composed of reprogramming factors associated with chromatin remodeling and neural lineage-specific factors. After being treated with reprosomes, fibroblasts were converted into NPCs (rNPCs) with great efficiency via activation of chromatin remodeling, so quickly that only 5 days were required for the formation of 1500 spheroids showing an NPC-like phenotype. The rNPCs maintained self-renewal and proliferative properties for several weeks and successfully differentiated into neurons, astrocytes, and oligodendrocytes in vitro and in vivo. Reprosome-mediated cellular reprogramming is simple, safe, and efficient to produce autologous stem cells for clinical application. PMID- 29462563 TI - Experimental Determination of Drug Diffusion Coefficients in Unstirred Aqueous Environments by Temporally Resolved Concentration Measurements. AB - The diffusion coefficient (also known as diffusivity) of an active pharmaceutical ingredient (API) is a fundamental physicochemical parameter that affects passive diffusion through biological barriers and, as a consequence, bioavailability and biodistribution. However, this parameter is often neglected, and it is quite difficult to find diffusion coefficients of small molecules of pharmaceutical relevance in the literature. The available methods to measure diffusion coefficients of drugs all suffer from limitations that range from poor sensitivity to high selectivity of the measurements or the need for dedicated instrumentation. In this work, a simple but reliable method based on time resolved concentration measurements by UV-visible spectroscopy in an unstirred aqueous environment was developed. This method is based on spectroscopic measurement of the variation of the local concentration of a substance during spontaneous migration of molecules, followed by standard mathematical treatment of the data in order to solve Fick's law of diffusion. This method is extremely sensitive and results in highly reproducible data. The technique was also employed to verify the influence of the environmental characteristics (i.e., ionic strength and presence of complexing agents) on the diffusivity. The method can be employed in any research laboratory equipped with a standard UV-visible spectrophotometer and could become a useful and straightforward tool in order to characterize diffusion coefficients in physiological conditions and help to better understand the drug permeability process. PMID- 29462564 TI - Practice Patterns of Referring Physicians in Management of the Dysphonic Patient. AB - Objective Dysphonia is commonly encountered by primary care physicians and general otolaryngologists. We examine practice patterns of referring physicians to a tertiary voice clinic, including adherence to evidence-based guidelines. Study Design Retrospective case series with chart review. Setting Academic tertiary care hospital. Subjects and Methods In total, 821 charts of patients with voice complaints seen at a tertiary voice clinic between January 2011 and June 2016 were reviewed. Included charts (n = 755) were reviewed for type of referring provider, prior diagnoses, and treatments employed by referring physicians. Additional information regarding findings at the time of laryngoscopy/stroboscopy and diagnoses provided by a laryngologist were also obtained. Statistical analysis was performed to determine significant relationships between variables of interest. Results A total of 244 patients (32.2%) received a diagnosis prior to evaluation in the voice clinic, most commonly laryngopharyngeal reflux disease (n = 134). Prior medical treatment was attempted in 221 (29.3%) patients, typically antireflux medications (n = 141). Of the patients treated with proton pump inhibitors by referring physicians, 65.1% lacked symptoms of gastroesophageal reflux disease. Patients with prior treatment had a median duration of symptoms 6 weeks longer than those without prior treatment ( P = .04). Among previously diagnosed patients, 199 (81.6%) of diagnoses changed after evaluation in the voice clinic. Conclusion Referring physicians frequently treat dysphonic patients empirically, often with antireflux medications. Subspecialist evaluation results in changes in diagnosis in many patients. Empiric treatment can delay referral and appropriate treatment. PMID- 29462565 TI - Pycnogenol protects against diet-induced hepatic steatosis in apolipoprotein-E deficient mice. AB - PycnogenolR (PYC), a combination of active flavonoids derived from French maritime pine bark, is a natural antioxidant that has various pharmacological activities. Here, we investigated the beneficial effect of PYC on diet-induced hepatic steatosis. Apolipoprotein E (ApoE)-deficient male mice were administered PYC at oral doses of 30 or 100 mg.kg-1.day-1 for 2 wk in advance and were then fed a high-cholesterol and -fat diet (HCD) for 8 wk. Biochemical, immunohistochemical, and gene expression analyses were conducted to explore the effect of PYC on lipid metabolism in ApoE-deficient mice on a HCD. Short-term treatment with HCD in ApoE-deficient mice induced hepatic injuries, such as lipid metabolism disorder and hepatic histopathological changes. We found that PYC reduced body weight and the increase of serum lipids that had been caused by HCD. Supplementation of PYC significantly reduced lipid deposition in the liver, as shown by the lowered hepatic lipid content and histopathological lesions. We subsequently detected genes related to lipid metabolism and inflammatory cytokines. The study showed that PYC markedly suppressed the expression of genes related to hepatic lipogenesis, fatty acid uptake, and lipid storage while increasing the lipolytic gene, which thus reduced hepatic lipid content. Furthermore, PYC mainly reduced the expression of inflammatory cytokines and the infiltration of inflammatory cells, which were resistant to the development of hepatic steatosis. These results demonstrate that PYC protects against the occurrence and development of hepatic steatosis and may provide a new prophylactic approach for nonalcoholic fatty liver disease (NAFLD).

PMID- 29462568 TI - Institutions, Incorporation, and Inequality: The Case of Minority Health Inequalities in Europe. AB - Scholars interested in the relationship between social context and health have recently turned attention further "upstream" to understand how political, social, and economic institutions shape the distribution of life chances across contexts. We compare minority health inequalities across 22 European countries ( N = 199,981) to investigate how two such arrangements-welfare state effort and immigrant incorporation policies-influence the distribution of health and health inequalities. We examine two measures of health from seven waves of the European Social Survey. Results from a series of multilevel mixed-effects models show that minority health inequalities vary across contexts and persist after accounting for socioeconomic differences. Cross-level interaction results show that welfare state effort is associated with better health for all groups but is unrelated to levels of inequality between groups. In contrast, policies aimed at protecting minorities from discrimination correlate with smaller relative health inequalities. PMID- 29462566 TI - Nonalcoholic fatty liver disease and gastric bypass surgery regulate serum and hepatic levels of pyruvate kinase isoenzyme M2. AB - Treatment of nonalcoholic fatty liver disease (NAFLD) focuses on the underlying metabolic syndrome, and Roux-en-Y gastric bypass surgery (RYGB) remains one of the most effective options. In rodents and human patients, RYGB induces an increase in the gene and protein expression levels of the M2 isoenzyme of pyruvate kinase (PKM2) in the jejunum. Since PKM2 can be secreted in the circulation, our hypothesis was that the circulating levels of PKM2 increase after RYGB. Our data, however, revealed an unexpected finding and a potential new role of PKM2 for the natural history of metabolic syndrome and NAFLD. Contrary to our initial hypothesis, RYGB-treated patients had decreased PKM2 blood levels compared with a well-matched group of patients with severe obesity before RYGB. Interestingly, PKM2 serum concentration correlated with body mass index before but not after the surgery. This prompted us to evaluate other potential mechanisms and sites of PKM2 regulation by the metabolic syndrome and RYGB. We found that in patients with NAFLD and nonalcoholic steatohepatitis (NASH), the liver had increased PKM2 expression levels, and the enzyme appears to be specifically localized in Kupffer cells. The study of murine models of metabolic syndrome and NASH replicated this pattern of expression, further suggesting a metabolic link between hepatic PKM2 and NAFLD. Therefore, we conclude that PKM2 serum and hepatic levels increase in both metabolic syndrome and NAFLD and decrease after RYGB. Thus, PKM2 may represent a new target for monitoring and treatment of NAFLD. PMID- 29462569 TI - Linguistic Integration and Immigrant Health: The Longitudinal Effects of Interethnic Social Capital. AB - The literature on immigrant health has by and large focused on the relationship between acculturation (often measured by a shift in language use) and health outcomes, paying less attention to network processes and the implications of interethnic integration for long-term health. This study frames English-language use among immigrants in the United States as a reflection of bridging social capital that is indicative of social network diversity. Using longitudinal data on self-rated health and the incidence of chronic conditions from the New Immigrant Survey (2003, 2007), I examine the contemporaneous and longitudinal associations between interethnic social capital and health. The results show evidence for a positive long-term effect of linguistic integration on health status, but no cross-sectional associations were observed. Overall, these results highlight the possible role of network processes in linking English-language use with immigrant health and the time-dependent nature of the relationship between linguistic integration and health status. PMID- 29462570 TI - Maternal Perceptions of Infant Feeding and Health in the Context of the 2015 Nepal Earthquake. AB - BACKGROUND: Displacement caused by the 2015 earthquake in Nepal exacerbated poor health and nutrition for thousands of women and children. Research aim: This study aimed to identify the perceptions of Nepalese mothers residing in earthquake relocation camps regarding barriers, facilitators, and situational factors influencing breastfeeding and family well-being. METHODS: An exploratory, rapid ethnographic approach was used during two fieldwork phases. Phase 1 consisted of reconnaissance and observation, whereas Phase 2 consisted of observation and qualitative semistructured interviews with infant caretakers ( N = 14). RESULTS: We found evidence of human milk substitutes donated by various groups after the earthquake, despite Nepal's media statement condemning these donations. Participants in this study expressed concerns about their milk supply. They also expressed concerns about the impending winter season combined with distress about the 2015 fuel crisis and the impact that this had on their infants and children. Furthermore, participants expressed choices about infant feeding that were influenced by traditional Nepalese practices. Specifically, homemade complementary foods and spices designed to boost lactation were identified as being used during daily infant feeding practices. CONCLUSION: Infant caretakers need culturally specific support for breastfeeding after disasters. These findings can directly influence future interventions concerning Nepalese mothers' perceptions, infant care, and feeding practices in disaster scenarios. PMID- 29462571 TI - Elucidating the Burden of HIV in Tissues Using Multiplexed Immunofluorescence and In Situ Hybridization: Methods for the Single-Cell Phenotypic Characterization of Cells Harboring HIV In Situ. AB - Persistent tissue reservoirs of HIV present a major barrier to cure. Defining subsets of infected cells in tissues is a major focus of HIV cure research. Herein, we describe a novel multiplexed in situ hybridization (ISH) (RNAscope) protocol to detect HIV-DNA (vDNA) and HIV-RNA (vRNA) in formalin-fixed paraffin embedded (FFPE) human tissues in combination with immunofluorescence (IF) phenotyping of the infected cells. We show that multiplexed IF and ISH (mIFISH) is suitable for quantitative assessment of HIV vRNA and vDNA and that multiparameter IF phenotyping allows precise identification of the cellular source of the ISH signal. We also provide semi-quantitative data on the impact of various tissue fixatives on the detectability of vDNA and vRNA with RNAscope technology. Finally, we describe methods to quantitate the ISH signal on whole slide digital images and validation of the quantitative ISH data with quantitative real-time PCR for vRNA. It is our hope that this approach will provide insight into the biology of HIV tissue reservoirs and to inform strategies aimed at curing HIV. PMID- 29462572 TI - Lactobacilli and bifidobacteria ameliorate memory and learning deficits and oxidative stress in beta-amyloid (1-42) injected rats. AB - The gastrointestinal microbiota affects brain function, including memory and learning. In this study we investigated the effects of probiotics on memory and oxidative stress biomarkers in an experimental model of Alzheimer's disease. Sixty rats were randomly divided into 5 groups: control; control-probiotics, which received probiotics for 8 weeks; sham operation, which received an intrahippocampal injection of phosphate-buffered saline; Alzheimer, which received an intrahippocampal injection of beta-amyloid (Abeta1-42); and Alzheimer probiotics, which in addition to being injected with Abeta1-42, received 2 g (1 * 1010 CFU/g) of probiotics (Lactobacillus acidophilus, L. fermentum, Bifidobacterium lactis, and B. longum) for 8 weeks. Memory and learning were measured using the Morris water maze, and oxidative stress biomarkers in the hippocampus were measured using ELISA kits. Morris water maze results indicated that compared with the Alzheimer group, the Alzheimer-probiotics group had significantly improved spatial memory, including shorter escape latency and travelled distance and greater time spent in the target quadrant. There was also improvement in oxidative stress biomarkers such as increased malondialdehyde levels and superoxide dismutase activity following the beta-amyloid injection. Overall, it seems that probiotics play a role in improving memory deficit and inhibiting the pathological mechanisms of Alzheimer's disease by modifying microbiota. PMID- 29462574 TI - Adiponectin receptor agonist AdipoRon decreased ceramide, and lipotoxicity, and ameliorated diabetic nephropathy. AB - BACKGROUND: Adiponectin is known to take part in the regulation of energy metabolism. AdipoRon, an orally-active synthetic adiponectin agonist, binds to both adiponectin receptors (AdipoR)1/R2 and ameliorates diabetic complications. Among the lipid metabolites, the ceramide subspecies of sphingolipids have been linked to features of lipotoxicity, including inflammation, cell death, and insulin resistance. We investigated the role of AdipoRon in the prevention and development of type 2 diabetic nephropathy. METHODS: AdipoRon (30 mg/kg) was mixed into the standard chow diet and provided to db/db mice (db + AdipoRon, n = 8) and age-matched male db/m mice (dm + AdipoRon, n = 8) from 17 weeks of age for 4 weeks. Control db/db (db cont, n = 8) and db/m mice (dm cont, n = 8) were fed a normal diet of mouse chow. RESULTS: AdipoRon-fed db/db mice showed a decreased amount of albuminuria and lipid accumulation in the kidney with no significant changes in serum adiponectin, glucose, and body weight. Restoring expression of adiponectin receptor-1 and -2 in the renal cortex was observed in db/db mice with AdipoRon administration. Consistent up-regulation of phospho-Thr172 AMP-dependent kinase (AMPK), peroxisome proliferative-activated receptor alpha (PPARalpha), phospho-Thr473 Akt, phospho-Ser79Acetyl-CoA carboxylase (ACC), and phospho Ser1177 endothelial NO synthase (eNOS), and down-regulation of protein phosphatase 2A (PP2A), sterol regulatory element-binding protein-1c (SREBP-1c), and inducible nitric oxide synthase (iNOS) were associated within the same group. AdipoRon lowered cellular ceramide levels by activation of acid ceramidase, which normalized ceramide to sphingosine-1 phosphate (S1P) ratio. In glomerular endothelial cells (GECs) and podocytes, AdipoRon treatment markedly decreased palmitate-induced lipotoxicity, which ultimately ameliorated oxidative stress and apoptosis. CONCLUSIONS: AdipoRon may prevent lipotoxicity in the kidney particularly in both GECs and podocytes through an improvement in lipid metabolism, as shown by the ratio of ceramide to sphingosines, and further contribute to prevent deterioration of renal function, independent of the systemic effects of adiponectin. The reduction in oxidative stress and apoptosis by AdipoRon provides protection against renal damage, thereby ameliorating endothelial dysfunction in type 2 diabetic nephropathy.

PMID- 29462576 TI - Dumbo octopod hatchling provides insight into early cirrate life cycle. AB - Cirrate octopods (Cephalopoda: Cirrata) are among the largest invertebrates of the deep sea. These organisms have long been known to lay single, large egg capsules on hard substrates on the ocean bottom [1], including cold-water octocorals (Anthozoa: Octocorallia). The egg capsule is comprised of an external egg case as well as the chorion and developing embryo. Development in cirrates proceeds for an extended time without parental care [2]. Although juveniles have previously been collected in the midwater [3], cirrate hatchlings have so far never been observed. Here, we provide the first video of a living hatchling and use magnetic resonance imaging (MRI) to analyze its anatomy and assign the specimen to the genus Grimpoteuthis, the so-called dumbo octopods. The specimen's behavior and advanced state of organ development show that cirrate hatchlings possess all morphological features required for movement via fin-swimming, for visually and chemically sensing their environment, and for prey capture. In addition, the presence of a large internal yolk sac reduces the risk of failure at first feeding. These data provide evidence that dumbo octopods hatch as competent juveniles. PMID- 29462577 TI - Gut glands illuminate trunk segmentation in Cambrian fuxianhuiids. AB - The euarthropod body consists of serially repeated segments with various degrees of functional specialization and regionalization [1]. Some representatives exhibit deviant metameric patterns expressed as an indirect correspondence between components of the exoskeleton, usually the number or position of dorsoventral sclerotized plates and walking legs (Supplemental Information) [1 3]. Segmental mismatch in the form of supernumerary walking legs per tergite (i.e. dorsal exoskeletal plate) is characteristic of fuxianhuiids, Cambrian euarthropods widely regarded as critical for understanding the origin of this phylum [4,5]. The broader significance of this organization remains obscure, however, due to the difficulty of distinguishing which components of the fuxianhuiid trunk reflect ancestral or derived traits. Here, we describe for the first time the presence of metameric midgut diverticulae in Fuxianhuia protensa from the Chengjiang Konservat-Lagerstatte and demonstrate that these digestive structures follow the segmentation pattern of the dorsal exoskeleton. Midgut diverticulae signal a predatory or scavenging ecology [6,7], falsifying the view of fuxianhuiids as simple mud-feeders [4]. Comparison with other euarthropods [1 3,5] indicates that fuxianhuiids possessed a unique mode of exoskeletal and visceral segmental mismatch, in which the tergites and midgut were segmentally patterned independently from the walking legs and ventral nerve cord. Our findings provide direct evidence of substantial developmental flexibility among stem-group euarthropods during the Cambrian.

AB - A popular new illusion shows that the apparent curvature of sinusoidal contours depends on contrast and background luminance.

PMID- 29462587 TI - Mitophagy and Quality Control Mechanisms in Mitochondrial Maintenance. AB - The maintenance of a healthy and functional mitochondrial network is critical during development as well as throughout life in the response to physiological adaptations and stress conditions. Owing to their role in energy production, mitochondria are exposed to high levels of reactive oxygen species, making them particularly vulnerable to mitochondrial DNA mutations and protein misfolding. Given that mitochondria are formed from proteins encoded by both nuclear and mitochondrial genomes, an additional layer of complexity is inherent in the coordination of protein synthesis and the mitochondrial import of nuclear-encoded proteins. For these reasons, mitochondria have evolved multiple systems of quality control to ensure that the requisite number of functional mitochondria are present to meet the demands of the cell. These pathways work to eliminate damaged mitochondrial proteins or parts of the mitochondrial network by mitophagy and renew components by adding protein and lipids through biogenesis, collectively resulting in mitochondrial turnover. Mitochondrial quality control mechanisms are multi-tiered, operating at the protein, organelle and cell levels. Herein, we discuss mitophagy in different physiological contexts and then relate it to other quality control pathways, including the unfolded protein response, shedding of vesicles, proteolysis, and degradation by the ubiquitin-proteasome system. Understanding how these pathways contribute to the maintenance of mitochondrial homeostasis could provide insights into the development of targeted treatments when these systems fail in disease. PMID- 29462588 TI - Posttranslational modification of heme in peroxidases - Impact on structure and catalysis. AB - Four heme peroxidase superfamilies arose independently in evolution. Only in the peroxidase-cyclooxygenase superfamily the prosthetic group is posttranslationally modified (PTM). As a consequence these peroxidases can form one, two or three covalent bonds between heme substituents and the protein. This may include ester bonds between heme 1- and 5-methyl groups and glutamate and aspartate residues as well as a sulfonium ion link between the heme 2-vinyl substituent and a methionine. Here the phylogeny and physiological roles of representatives of this superfamily, their occurrence in all kingdoms of life, the relevant sequence motifs for definite identification and the available crystal structures are presented. We demonstrate the autocatalytic posttranslational maturation process and the impact of the covalent links on spectral and redox properties as well as on catalysis, including Compound I formation and reduction by one- and two electron donors. Finally, we discuss the evolutionary advantage of these PTMs with respect to the proposed physiological functions of the metalloenzymes that range from antimicrobial defence in innate immunity to extracellular matrix formation and hormone biosynthesis. PMID- 29462589 TI - Potentiation of skin TSLP production by a cosmetic colorant leads to aggravation of dermatitis symptoms. AB - Certain cosmetic colorants are irritant to skin or aggravate dermatitis. Thymic stromal lymphopoietin (TSLP) plays an important role in the initiation and progress of skin inflammation and atopic dermatitis by triggering Th2 immune responses. However, the effects of cosmetic colorants on TSLP production are unknown yet. Therefore, we investigated whether cosmetic colorants regulated TSLP production and dermatitis. Lithol Rubine B (LR-B, Pigment Red 57) and its calcium salt (LR-BCA), commonly used cosmetic colorants, potentiated phorbol-12-myristate 13-acetate-induced TSLP production in keratinocytes. In addition, the topical exposure to LR-B or LR-BCA on mouse ear upregulated a TSLP inducer (MC903) induced TSLP production and Th2 cytokine expression. Dermatitis symptoms and serum IgE and histamine levels were also aggravated by LR-B or LR-BCA, implicating the role of increased TSLP expression in acute dermatitis. LR-B or LR BCA induced IkappaBalpha degradation and NF-kappaB activation in keratinocytes, leading to TSLP expression. Collectively, our results demonstrate that LR-B and LR-BCA increase TSLP expression and Th2 immune responses, thereby aggravating acute dermatitis in the compromised skin. The results further suggest that certain cosmetic colorants such as LR-B may aggravate dermatitis under pro inflammatory conditions by upregulating TSLP production. PMID- 29462590 TI - Lipid bilayer stress in obesity-linked inflammatory and metabolic disorders. AB - The maintenance of the characteristic lipid compositions and physicochemical properties of biological membranes is essential for their proper function. Mechanisms allowing to sense and restore membrane homeostasis have been identified in prokaryotes for a long time and more recently in eukaryotes. A membrane remodeling can result from aberrant metabolism as seen in obesity. In this review, we describe how such lipid bilayer stress can account for the modulation of membrane proteins involved in the pathogenesis of obesity-linked inflammatory and metabolic disorders. We address the case of the Toll-like receptor 4 that is implicated in the obesity-related low grade inflammation and insulin resistance. The lipid raft-mediated TLR4 activation is promoted by an enrichment of the plasma membrane with saturated lipids or cholesterol increasing the lipid phase order. We discuss of the plasma membrane Na, K-ATPase that illustrates a new concept according to which direct interactions between specific residues and particular lipids determine both stability and activity of the pump in parallel with indirect effects of the lipid bilayer. The closely related sarco(endo)-plasmic Ca-ATPase embedded in the more fluid ER membrane seems to be more sensitive to a lipid bilayer stress as demonstrated by its inactivation in cholesterol-loaded macrophages or its inhibition mediated by an increased PtdCho/PtdEtn ratio in obese mice hepatocytes. Finally, we describe the model recently proposed for the activation of the conserved IRE-1 protein through alterations in the ER membrane lipid packing and thickness. Such IRE-1 activation could occur in response to abnormal lipid synthesis and membrane remodeling as observed in hepatocytes exposed to excess nutrients. Since the IRE-1/XBP1 branch also stimulates the lipid synthesis, this pathway could create a vicious cycle "lipogenesis-ER lipid bilayer stress-lipogenesis" amplifying hepatic ER pathology and the obesity-linked systemic metabolic defects.

AB - BACKGROUND: This study aimed to compare the survival rates after lobectomy, segmentectomy, and wedge resection for the eighth edition of the tumor, node, metastasis classification for stage IA non-small cell lung cancer (NSCLC). METHODS: Patients who underwent lobectomy, segmentectomy, or wedge resection for stage IA NSCLC were identified from the Surveillance, Epidemiology, and End Results database. A Cox regression model and propensity-matched analysis were used. The overall survival (OS) rates and lung cancer-specific survival (LCSS) rates among the three groups were compared by tumor size. RESULTS: A total of 16,819 patients met our criteria. Although the OS rate was better for lobectomy than for wedge resection, no statistical differences in the LCSS rate were identified among the three treatment groups of patients with tumors that were 1.0 cm or smaller. For tumors from 1.1 to 2.0 cm, lobectomy and segmentectomy showed no statistical differences in the LCSS rate, but both conferred better OS and LCSS rates than wedge resection. For tumors from 2.1 to 3.0 cm, the OS and LCSS rates were better for lobectomy than for segmentectomy or wedge resection, but similar for segmentectomy and wedge resection. CONCLUSIONS: Lobectomy, segmentectomy, and wedge resection are comparable oncologic procedures for patients with stage IA NSCLC that is 1.0 cm or smaller. For tumors from 1.1 to 2.0 cm, lobectomy and segmentectomy could lead to equivalent survival rates but showed better survival rates than that observed with wedge resection. For tumors from 2.1 to 3.0 cm, lobectomy is still the standard surgical procedure; for patients who are unsuitable candidates for lobectomy, segmentectomy and wedge resection show similar survival rates. PMID- 29462592 TI - Platelet-lymphocyte ratio acts as an independent predictor of prognosis in patients with renal cell carcinoma. AB - BACKGROUND: The prognostic value of plated-lymphocyte ratio (PLR) in multiple malignancies had been investigated in previous studies; however, its prognostic value in renal cell carcinoma (RCC) remains controversial. This study was performed to assess the prognostic value of preoperative PLR in RCC patients. METHODS: Literature was searched from PubMed, Embase, Web of Science and Cochrane database, which evaluated the relationships between preoperative PLR and prognosis in RCC patients. Hazard ratios (HRs) for overall survival (OS) and progression-free survival (PFS) were extracted from eligible studies. Heterogeneity was assessed using the I2 value. The fixed-effects model was used if there was no evidence of heterogeneity; otherwise, the random-effects model was used. Publication bias was evaluated using Begg's funnel plots and Egger's regression test. RESULTS: A total of 1528 patients from seven studies were included in the analysis. The pooled analysis showed that an elevated PLR was an effective prognostic marker of both OS (pooled HR = 2.10, 95%CI: 1.38-3.19, p = 0.001) and PFS (pooled HR = 3.45, 95%CI: 1.61-7.40, p = 0.001). Subgroup analysis revealed that a high PLR significantly predicted worse OS and PFS in Asian studies (OS, pooled HR = 2.72, 95%CI: 1.06-7.03, p = 0.038; PFS, pooled HR = 6.0, 95%CI: 3.12-11.54, p < 0.001), in metastatic RCC patients receiving mixed therapies (OS, pooled HR = 3.69, 95%CI: 1.93-11.42, p = 0.023; PFS, pooled HR = 6.05, 95%CI: 1.34-27.37, p = 0.019) and targeted therapy (OS, pooled HR = 1.59, 95%CI: 0.97-2.62, p = 0.067), in sample size >100 (OS, pooled HR = 1.83, 95%CI: 1.49-2.25, p < 0.001; PFS pooled HR = 6.05, 95%CI: 1.34-27.37, p < 0.019), and in cut-off value of PLR <= 195 (OS, pooled HR = 3.65, 95%CI: 1.06-12.60, p = 0.04; PFS pooled HR 4.46, 95%CI: 1.68-11.87, p = 0.003). CONCLUSIONS: This study suggests that a high preoperative PLR is correlated with poor prognosis in RCC patients. PMID- 29462593 TI - Carboxymethylated chitosan protects Schwann cells against hydrogen peroxide induced apoptosis by inhibiting oxidative stress and mitochondria dependent pathway. AB - Carboxymethylated chitosan (CMCS) has many beneficial effects, including anti oxidant and anti-apoptotic actions. However, the mechanisms by which CMCS protect against oxidative stress induced damage to Schwann cells (SCs) remains unclear. The present study aimed to investigate the mechanism by which CMCS protects SCs against hydrogen peroxide (H2O2) induced damage. H2O2 was used to establish a model of oxidative stress injury in SCs to mimic the development of nerve injury in vitro. Different concentrations (50, 100 and 200 ug/ml) of CMCS were added to test whether CMCS was capable of protecting SCs from H2O2 induced damage. MTT, LDH release and Annexin V/FITC assays were then performed. Levels of reactive oxygen species were detected using a reactive oxygen species assay kit, the mitochondrial membrane potential (DeltaPsim) of SCs was analyzed by rhodamine123 fluorescence staining, the synthesis of Bcl-2, Bax, cytochrome c and caspase-3 were analyzed by real-time PCR and Western blot analysis. The results showed that CMCS protected SCs from apoptosis, decreased LDH release and enhanced cell viability, also decreased reactive oxygen species levels and increased DeltaPsim. Additional experiments demonstrated that CMCS could decrease protein expression of Bax, cytochrome c and caspase-3, while promote Bcl-2 protein expression induced by H2O2. Taken together, the finding of this study indicated that CMCS prevented H2O2-induced damage to SCs through the mitochondrial dependent pathway. PMID- 29462595 TI - Simultaneous detection of Mycoplasma pneumoniae IgG and IgM using dual-label time resolved fluoroimmunoassay. AB - Anti-Mycoplasma pneumoniae (MP) IgM and IgG are useful serological markers for detection of MP infection. In this study, a simultaneous quantification of MP IgM and IgG was performed by time-resolved fluoroimmunoassay (TRFIA). The europium labeled anti-human IgM and samarium-labeled anti-human IgG were used as tracers, and MP IgM and IgG were recognized in serum samples. After dissociating europium and samarium ions from the immune complex, their fluorescence intensity was recorded and used to calculate the concentrations. The linear range and sensitivity of detection were 2-5500 BU/mL and 0.5 BU/mL for IgM, and 1.5-1500 BU/mL and 0.2 BU/mL for IgG, respectively. The intra- and inter-assay coefficients of variation were 5.14% and 8.41% for IgM, and 5.44% and 8.76% for IgG, respectively. The recovery rate was 94.9-106.8% for IgM and 96.1-109.4% for IgG. The correlation rates of serum detection for 38 respiratory infected patients between dual-label TRFIA and ELISA were 0.9294 and 0.9366 for IgM and IgG, respectively. The coincidence rate between passive particle agglutination and TRFIA is 93.3%. Dual-label TRFIA is a sensitive and reliable technique for measuring MP IgM and IgG levels and could be useful for the early diagnosis of MP infection. PMID- 29462594 TI - Melatonin promotes neuroprotection of induced pluripotent stem cells-derived neural stem cells subjected to H2O2-induced injury in vitro. AB - Melatonin is a neurohormone mainly extracted from the pineal gland with neuroprotective effects. It has antioxidant, anti-inflammatory, and antiapoptotic functions. However, the mechanism of melatonin against reactive oxygen species is unclear. Here, we explore the potential proliferative and neuroprotective mechanism of melatonin on induced pluripotent stem cells (iPSC)-derived neural stem cells (NSCs) exposed to hydrogen peroxide (H2O2). NSCs were induced from iPSCs, then pretreated with 500 MUM H2O2, 1 MUM melatonin, 1 MUM melatonin receptor antagonist (Luzindole), or 10 MUM Phosphatidylinositide 3 kinase (PI3K) inhibitor (LY294002). The results showed that melatonin stimulated proliferation of iPSC-derived NSCs on H2O2 exposure. Melatonin also markedly improved stabilization of the mitochondrial membrane potential and reduced the rate of apoptosis. Treatment with Luzindole or LY294002 inhibited the increasing proliferative and neuroprotective effects of melatonin on iPSC-derived NSCs with H2O2 treatment. Our results further demonstrated that these promotional effects of melatonin were related with the activity of phosphorylation of AKT. Therefore, these outcomes propose that melatonin protects iPSC-derived NSCs from H2O2 induced injury through the mediation of melatonin receptor and PI3K/AKT signaling pathway. PMID- 29462596 TI - Onabotulinumtoxin type A improves lower urinary tract symptoms and quality of life in patients with human T cell lymphotropic virus type 1 associated overactive bladder. AB - AIM: To evaluate the efficacy of the onabotulinum toxin type A in the treatment of HTLV-1 associated overactive bladder and its impact on quality of life (QoL). METHODS: Case series with 10 patients with overactive bladder refractory to conservative treatment with anticholinergic or physical therapy. They received 200Ui of onabotulinumtoxin type A intravesically and were evaluated by overactive bladder symptoms score (OABSS) and King's Health Questionnaire. RESULTS: The mean (SD) of the age was 52+14.5 years and 60% were female. All of them had confirmed detrusor overactivity on urodynamic study. Seven patients had HAM/TSP. The median and range of the OABSS was 13 (12-15) before therapy and decreased to 1.0 (0-12) on day 30 and to 03 (0-14) on day 90 (p<0.0001). There was a significant improvement in 8 of the 9 domains of the King's Health Questionnaire after the intervention. Hematuria, urinary retention and urinary infection were the complications observed in 3 out of 10 patients. The mean time to request retreatment was 465 days. CONCLUSION: Onabotulinum toxin type A intravesically reduced the OABSS with last long effect and improved the quality of life of HTLV 1 infected patients with severe overactive bladder. PMID- 29462597 TI - Validity and Reliability of Outcome Measures Assessing Dexterity, Coordination, and Upper Limb Strength in Autosomal Recessive Spastic Ataxia of Charlevoix Saguenay. AB - OBJECTIVE: To document in adults affected by autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) the intra- and interrater reliability, standard error of measurement, agreement, minimal detectable change, and construct validity of the 9-Hole Peg Test (NHPT), the Standardized Finger-to-Nose Test (SFNT), and grip strength. DESIGN: Metrologic study. SETTING: Neuromuscular rehabilitation clinic. PARTICIPANTS: Genetically confirmed adult patients with ARSACS (N=42; 21 women; mean age, 38.6y). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Intra- and interrater reliability was determined using the intraclass correlation coefficient (ICC). Construct validity was determined by assessing the capacity of the NHPT, the SFNT, and grip strength to distinguish between participants based on sex, mobility stages, and age groups, and on performance on the Archimedes spiral and fast alternating hand movements tests. RESULTS: All 3 tests have shown excellent reliability (ICC=.90-.98). However, the limit of agreement was influenced by the participant's performance on the NHPT, and the minimal detectable change was very different for both hands (right=9.7 vs left=28.0). Construct validity was confirmed for the SFNT and NHPT, but it was not demonstrated for grip strength. CONCLUSIONS: Given the metrologic properties assessed in this study, the SFNT is an excellent measure to assess upper limb coordination, whereas the NHPT must be used with caution. The grip strength is reliable but does not seem to reflect disease severity. PMID- 29462598 TI - Using adult Aedes aegypti females to predict areas at risk for dengue transmission: A spatial case-control study. AB - INTRODUCTION: Traditional indices for measuring dengue fever risk in a given area are based on the immature forms of the vector (larvae and pupae surveys). However, this is inefficient because only adult female mosquitoes actually transmit the virus. Based on these assumptions, our objective was to evaluate the association between an entomological index obtained from adult mosquito traps and the occurrence of dengue in a hyperendemic area. Additionally, we compared its cost to that of the Breteau Index (BI). MATERIAL AND METHODS: We performed this study in Sao Jose do Rio Preto, SP, Brazil, between the epidemiological weeks of 36/2012 and 19/2013. BG-Sentinel and BG-Mosquitito traps were installed to capture adult mosquitoes. Positive and negative cases of dengue fever were computed and geocoded. We generated biweekly thematic maps of the entomological index, generated by calculating the number of adult Aedes aegypti females (NAF) per 100 households during a week by kriging, and based on the number of mosquitoes captured. The relation between the occurrence of dengue fever and the NAF was tested using a spatial case-control design and a generalized additive model and was controlled by the coordinates of the positive and negative cases of dengue fever. RESULTS: Our analyses showed that increases in dengue fever cases occurred in parallel with increases in the number of Ae. aegypti females. The entomological index produced in our study correlates positively with the incidence of dengue, particularly during intervals when vector control measures were applied less intensively. The operational costs of our index were lower than those of the BI: NAF used 71.5% less human resources necessary to measure the BI. CONCLUSIONS: Spatial analysis techniques and the number of adult Ae. aegypti females were used to produce an indicator of dengue risk. The index can be applied at various levels of spatial aggregation for an entire study area, as well as for sub-areas, such as city blocks. Even though the index is adequate to predict dengue risk, it should be tested and validated in various scenarios before routine use. PMID- 29462599 TI - Involvement of 11-ketotestosterone in hooknose formation in male pink salmon (Oncorhynchus gorbuscha) jaws. AB - Mature male Pacific salmon (Oncorhynchus spp.) develop a hooknose, as a secondary male sexual characteristic, during the spawning period. It is likely that androgens regulate hooknose formation. However, endocrinological and histochemical details about the relationship between androgens and hooknose formation are poorly understood. In this study, we performed assays of serum androgens, detection of androgen receptor (AR) in hooknose tissues, external morphological measurement of hooknose-related lengths, and microscopic observation of hooknose tissues of pink salmon (O. gorbuscha) at different stages of sexual maturation. Expression of the arbeta gene was detected in hooknose tissues of males but not females. The elongation of these tissues was mediated directly via androgens. Serum 11-ketotestosterone (11-KT) concentrations indicated a significant positive correlation with both jaw lengths during sexual maturation of males. In the upper jaw, cartilage tissue developed during hooknose formation, and AR-immunoreactive chondrocytes were located in the rostal-vetral regions of hooknose cartilage in maturing male. The chondrocytes in maturing males before entering into rivers exhibited rich-cytoplasm with high cell activity than at other sexual development stages. On the other hand, in the lower jaw, the development of the spongiosa-like bone meshworks. AR-immunoreactivity was detected in a proportion of the osteocytes and osteoblast-like cells in the spongiosa-like bone meshworks. These results indicate that hooknose formation in pink salmon, which is associated with the buildup of a structure with sufficient strength that it can be used to attack other males on the spawning ground, is regulated by 11-KT. PMID- 29462600 TI - Snow cover and snowfall impact corticosterone and immunoglobulin a levels in a threatened steppe bird. AB - Birds use both the corticosterone stress response and immune system to meet physiological challenges during exposure to adverse climatic conditions. To assess the stress level and immune response of the Asian Great Bustard during conditions of severe winter weather, we measured fecal corticosterone (CORT) and Immunoglobulin A (IgA) before and after snowfall in a low snow cover year (2014) and a high snow cover year (2015). A total of 239 fecal samples were gathered from individuals in Tumuji Nature Reserve, located in eastern Inner Mongolia, China. We observed high CORT levels that rose further after snowfall both in high and low snow cover years. IgA levels increased significantly after snowfall in the low snow cover year, but decreased after snowfall in the high snow cover year. These results suggest that overwintering Asian Great Bustards are subjected to climatic stress during severe winter weather, and the hypothalamic-pituitary adrenal axis and immune system react to this challenge. Extreme levels of stress, such as snowfall in already prolonged and high snow cover conditions may decrease immune function. Supplemental feeding should be considered under severe winter weather conditions for this endangered subspecies. PMID- 29462602 TI - 6-Shogaol induces caspase-independent paraptosis in cancer cells via proteasomal inhibition. AB - An alpha, beta-unsaturated carbonyl compound of ginger, 6-Shogaol (6S), induced extensive cytoplasmic vacuolation and cell death in breast cancer cell (MDA-MB 231) and non-small lung cancer (A549) cells. In the presence of autophagic inhibitors the cells continued to exhibit cytoplasmic vacuolation and cell death clearly distinguishing it from the classic autophagic process. 6S induced death did not exhibit the characteristic apoptotic features like caspase cleavage, phosphatidyl serine exposure and DNA fragmentation. The immunofluorescence with the Endoplasmic Reticulum (ER) resident protein, calreticulin indicated that the vacuoles were of ER origin, typical of paraptosis. This was supported by the increase in level of microtubule associated protein light chain 3B (LC3 I and LC3 II) and polyubiquitin binding protein, p62. The level of ER stress markers like polyubiquitinated proteins, Bip and CHOP also consistently increased. We have found that 6S inhibits the 26S proteasome. The proteasomal inhibitory activity was elucidated by a) molecular docking of 6S onto the active site of beta5 subunit and b) reduced fluorescence by the fluorogenic substrate of the chymotrypsin-like subunit. In conclusion these studies demonstrate for the first time that proteasomal inhibition by 6S induces cell death via paraptosis. So 6 shogaol may act as a template for anti-cancer lead discovery against the apoptosis resistant cancer cells. PMID- 29462601 TI - Novel Developments in Endoscopic Mucosal Imaging. AB - Endoscopic techniques such as high-definition and optical-chromoendoscopy have had enormous impact on endoscopy practice. Since these techniques allow assessment of most subtle morphological mucosal abnormalities, further improvements in endoscopic practice lay in increasing the detection efficacy of endoscopists. Several new developments could assist in this. First, web based training tools could improve the skills of the endoscopist for enhancing the detection and classification of lesions. Secondly, incorporation of computer aided detection will be the next step to raise endoscopic quality of the captured data. These systems will aid the endoscopist in interpreting the increasing amount of visual information in endoscopic images providing real-time objective second reading. In addition, developments in the field of molecular imaging open opportunities to add functional imaging data, visualizing biological parameters, of the gastrointestinal tract to white-light morphology imaging. For the successful implementation of abovementioned techniques, a true multi-disciplinary approach is of vital importance. PMID- 29462603 TI - LOX-1 receptor: A potential link in atherosclerosis and cancer. AB - Altered production of reactive oxygen species (ROS), causing lipid peroxidation and DNA damage, contributes to the progression of atherosclerosis and cancer. Lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) is a lectin-like receptor for oxidized low-density lipoproteins (ox-LDL) primarily expressed in endothelial cells and vasculature-rich organs. LOX-1 receptors is a marker for atherosclerosis, and once activated by ox-LDL or other ligands, stimulates the expression of adhesion molecules, pro-inflammatory signaling pathways and proangiogenic proteins, including NF-kB and VEGF, in vascular endothelial cells and macrophages. Several different types of cancer reported LOX-1 gene upregulation, and numerous interplays exist concerning LOX-1 in atherosclerosis, metabolic diseases and cancer. One of them involves NF-kB, an oncogenic protein that regulates the transcription of several inflammatory genes response. In a model of cellular transformation, the MCF10A ER-Src, inhibition of LOX-1 gene reduces NF-kB activation and the inflammatory and hypoxia pathways, suggesting a mechanistic connection between cellular transformation and atherosclerosis. The remodeling proteins MMP-2 and MMP-9 have been found increased in angiogenesis in atherosclerotic plaque and also in human prostate cancer cells. In this review, we outlined the role of LOX-1 in atherogenesis and tumorigenesis as a potential link in these diseases, suggesting that LOX-1 inhibition could represent a promising strategy in the treatment of atherosclerosis and tumors. PMID- 29462604 TI - Enhanced detection of infectious prions by direct ELISA from the brains of asymptomatic animals using DRM2-118 monoclonal antibody and Gdn-HCl. AB - In this report we describe the use of a novel anti-prion monoclonal antibody (DRM2-118) for the direct detection of infectious prions by ELISA. Epitope mapping using overlapping hamster (SHa) prion peptides indicates DRM2-118 binding occurs between residues 93-100 and at the 310-helix (residues 163-170) between alpha helix-A and -B. This antibody shows broad species binding to endogenous prions from brain homogenates and corresponding recombinant prion proteins. To evaluate the performance of this MAb for the detection of prion proteins we performed an animal time course and evaluated prion detection from both crude brain homogenates and lipid raft fractions (DRM) by direct ELISA. Prion detection was significantly enhanced by the addition of the chaotropic guanidine-HCl (Gdn HCl) during protein immobilization with detection of PK-resistant prion from asymptomatic animal brains at (45-DPI) and from lipid rafts at (24-DPI). Our data demonstrates enhanced prion detection from brain lipid rafts of asymptomatic animals by a simple direct ELISA using the DRM2-118 MAb combined with Gdn-HCl. PMID- 29462605 TI - Performance evaluation of phage-displayed synthetic human single-domain antibody libraries: A retrospective analysis. AB - Fully human synthetic single-domain antibodies (sdAbs) are desirable therapeutic molecules but their development is a considerable challenge. Here, using a retrospective analysis of in-house historical data, we examined the parameters that impact the outcome of screening phage-displayed synthetic human sdAb libraries to discover antigen-specific binders. We found no evidence for a differential effect of domain type (VH or VL), library randomization strategy, incorporation of a stabilizing disulfide linkage or sdAb display format (monovalent vs. multivalent) on the probability of obtaining any antigen-binding human sdAbs, instead finding that the success of library screens was primarily related to properties of target antigens, especially molecular mass. The solubility and binding affinity of sdAbs isolated from successful screens depended both on properties of the sdAb libraries (primarily domain type) and the target antigens. Taking attrition of sdAbs with major manufacturability concerns (aggregation; low expression) and sdAbs that do not recognize native cell-surface antigens as independent probabilities, we calculate the overall likelihood of obtaining >=1 antigen-binding human sdAb from a single library-target screen as ~24%. Successful library-target screens should be expected to yield ~1.3 human sdAbs on average, each with average binding affinity of ~2 MUM. PMID- 29462606 TI - Limb remote ischemic post-conditioning mitigates brain recovery in a mouse model of ischemic stroke by regulating reactive astrocytic plasticity. AB - Maladaptive alterations of astrocytic plasticity may cause brain edema in the acute stage of stroke and glial scar formation in the recovery stage. The present study was designed to investigate the potential regulation of limb remote ischemic post-conditioning (RIPC) on astrocytic plasticity in experimental cerebral ischemia-reperfusion injury. Cerebral ischemia was induced by transient middle cerebral artery occlusion (tMCAO) for 1 h in C57BL/6 mice, who were treated with RIPC immediately after reperfusion. The results showed that RIPC decreased hemispheric swelling, infarct volume and brain atrophy, and increased neurological function recovery and survival rates of ischemic mice at 3 and 14 d after cerebral ischemia-reperfusion, respectively. Moreover, the proportion of astrocyte subtypes was adjusted by RIPC treatment, demonstrated by decreased expression of the fibrous type (glial fibrillary acidic protein, GFAP) and increased expression of the protoplasmic type (glutamine synthetase, GS) in the ipsilateral side of the mouse brain at 14 d after cerebral ischemia-reperfusion. RIPC treatment adjusted the proportion of GFAP subtypes by downregulating the protein level of GFAPalpha, as well as upregulating the GFAPdelta/GFAPalpha ratio in the ipsilateral side at 3 and 14 d after reperfusion. Notably, RIPC inhibited the phosphorylation of signal transducer and activators of transcriptions 3 (p STAT3) in the ipsilateral side at 3 and 14 d after cerebral ischemia-reperfusion. Taken together, the results show that RIPC treatment could regulate reactive astrocytic plasticity and inhibition of STAT3 phosphorylation to promote neurological function recovery following ischemic stroke. PMID- 29462607 TI - Ascorbic acid ameliorates lead-induced apoptosis in the cerebellar cortex of developing rats. AB - We investigated the effects of the gestational administration of lead (Pb) and ascorbic acid on cerebellar development. Pregnant female rats were randomly assigned to the control, Pb, or Pb plus ascorbic acid (PA) groups; six offspring per cage were randomly selected for analysis. Compared to the control group, fewer Purkinje cells were observed in the Pb-exposed pups at postnatal day 21. However, co-administrating Pb and ascorbic acid inhibited the Pb-induced reduction in Purkinje cells. Terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL) staining, which detected DNA fragmentation in the dying cells, showed more TUNEL-positive cells in the Pb group, while co-treatment with Pb and ascorbic acid mitigated the Pb-induced cellular degeneration. Using immunohistochemistry and immunoblotting, we additionally found that Pb exposure induced a rise in the apoptotic factor Bax in the cerebellum, while Pb plus ascorbic acid treatment ameliorated this Bax induction. Since, Pb competes with the iron in the cell and the accumulation of free iron triggers oxidative stress, we performed iron staining, which revealed that ascorbic acid prevented the Pb induced rises in iron-reactive cells and iron-reactivity. The anti-oxidant enzyme manganese-dependent superoxide dismutase showed change patterns that were similar to those of iron in the cerebellum. Finally, the pups' blood Pb levels were highest in the Pb group but were reduced in the PA group. Our findings suggest that ascorbic acid effectively ameliorates Pb-induced apoptosis and oxidative stress in the cerebellum. The present results imply that ascorbic acid treatment during pregnancy may protect against Pb-mediated developmental impairments in the cerebellum. PMID- 29462609 TI - Contextual constraints on lexico-semantic processing in aging: Evidence from single-word event-related brain potentials. AB - The current study reports the effects of accumulating contextual constraints on neural indices of lexico-semantic processing (i.e., effects of word frequency and orthographic neighborhood) as a function of normal aging. Event-related brain potentials were measured from a sample of older adults as they read sentences that were semantically congruent, provided only syntactic constraints (syntactic prose), or were random word strings. A linear mixed-effects modeling approach was used to probe the effects of accumulating contextual constraints on N400 responses to individual words. Like young adults in prior work, older adults exhibited a classic word position context effect on the N400 in congruent sentences, although the magnitude of the effect was reduced in older relative to younger adults. Moreover, by modeling single-word variability in N400 responses, we observed robust effects of orthographic neighborhood density that were larger in older adults than the young, and preserved effects word frequency. Importantly, in older adults, frequency effects were not modulated by accumulating contextual constraints, unlike in the young. Collectively, these findings indicate that older adults are less likely (or able) to use accumulating top-down contextual constraints, and therefore rely more strongly on bottom-up lexical features to guide semantic access of individual words during sentence comprehension. PMID- 29462610 TI - Spinal muscular atrophy: Selective motor neuron loss and global defect in the assembly of ribonucleoproteins. AB - Spinal muscular atrophy is caused by deletions or mutations in the SMN1 gene that result in reduced expression of the SMN protein. The SMN protein is an essential molecular chaperone that is required for the biogenesis of multiple ribonucleoprotein (RNP) complexes including spliceosomal small nuclear RNPs (snRNPs). Reductions in SMN expression result in a reduced abundance of snRNPs and to downstream RNA splicing alterations. SMN is also present in axons and dendrites and appears to have important roles in the formation of neuronal mRNA protein complexes during development or neuronal repair. Thus, SMA is an exemplar, selective motor neuron disorder that is caused by defects in fundamental RNA processing events. A detailed molecular understanding of how motor neurons fail, and why other neurons do not, in SMA will yield important principals about motor neuron maintenance and neuronal specificity in neurodegenerative diseases. PMID- 29462611 TI - MiR-29 family members interact with SPARC to regulate glucose metabolism. AB - MicroRNA (miR)-29 family members have been reported to play important regulatory roles in metabolic disease. We used TargetScan to show that "secreted protein acidic rich in cysteine" (SPARC) is a target of the miR-29s. SPARC is a multifunctional secretory protein involved in a variety of biological activities, and SPARC dysregulation is associated with a wide range of obesity-related disorders, including type 2 diabetes mellitus (T2DM). We explored whether miR-29s played roles in glucose metabolism and whether miR-29s directly targeted SPARC. We also examined the effect of SPARC on glucose metabolism and how the association of miR-29s with SPARC affected glucose metabolism. We found that overexpression of miR-29s reduced glucose uptake and GLUT4 levels; that miR-29 directly targeted SPARC, resulting in degradation of SPARC-encoding mRNA and reduction in the SPARC protein level; that SPARC increased glucose uptake and GLUT4 levels; that shRNA-mediated knockdown of SPARC reduced GLUT4 protein levels in 3T3-L1 adipocytes; that miR-29s reduced glucose uptake and GLUT4 levels; and that miR-29s inhibited glucose uptake by suppressing SPARC synthesis. Thus, the miR-29 family negatively regulates glucose metabolism by inhibiting SPARC expression. PMID- 29462612 TI - N-terminus plus linker domain of Mg-chelatase D subunit is essential for Mg chelatase activity in Oryza sativa. AB - Mg chelatase, a key enzyme in chlorophyll biosynthesis, is comprised of I, D and H subunits. Among these subunits, the D subunit was regarded to mediate protein interactions due to its unique protein domains. However, the functional roles of the different domains of the D subunit in vivo remain unclear. In this study, we dissected the rice (Oryza sativa) D subunit (OsCHLD) into three peptide fragments: the putative chloroplast transit peptide (TP, Met1 to Arg45), the N terminus plus linker domain (OsCHLDN + L, Ala46 to Leu485) and the C-terminus (OsCHLDC, Ile486 to Ser754), to explore the roles of these fragments. The results of the yeast two-hybrid assay and the in vitro reconstitution of the Mg-chelatase activity showed that only OsCHLDN + L interacted with the I and H subunits and maintained most of the Mg-chelatase activity in vitro. Furthermore, artificial TP OsCHLDN + L and TP-OsCHLDC were overexpressed in rice. Interestingly, an incomplete co-suppression had occurred in both of the overexpressed (OsCHLDN + L ox and OsCHLDC-ox) plants, resulting in a significantly downregulated expression of endogenous OsCHLD. Therefore, these transgenic plants had adequate OsCHLDN + L and OsCHLDC instead of endogenous OsCHLD, providing ideal models to study the function of different domains of the D subunit in vivo. The OsCHLDN + L-ox plants showed an identical phenotype to that of the wild type, while the OsCHLDC-ox plants demonstrated a yellowish phenotype that resembled the D subunit mutants. These results indicated that only OsCHLDN + L could complement the function of endogenous OsCHLD, providing direct evidence that OsCHLDN + L is essential for Mg chelatase activity in vivo. PMID- 29462608 TI - mRNP assembly, axonal transport, and local translation in neurodegenerative diseases. AB - The development, maturation, and maintenance of the mammalian nervous system rely on complex spatiotemporal patterns of gene expression. In neurons, this is achieved by the expression of differentially localized isoforms and specific sets of mRNA-binding proteins (mRBPs) that regulate RNA processing, mRNA trafficking, and local protein synthesis at remote sites within dendrites and axons. There is growing evidence that axons contain a specialized transcriptome and are endowed with the machinery that allows them to rapidly alter their local proteome via local translation and protein degradation. This enables axons to quickly respond to changes in their environment during development, and to facilitate axon regeneration and maintenance in adult organisms. Aside from providing autonomy to neuronal processes, local translation allows axons to send retrograde injury signals to the cell soma. In this review, we discuss evidence that disturbances in mRNP transport, granule assembly, axonal localization, and local translation contribute to pathology in various neurodegenerative diseases, including spinal muscular atrophy (SMA), amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), and Alzheimer's disease (AD). PMID- 29462613 TI - Chlamydia pneumoniae infection promotes monocyte transendothelial migration by increasing vascular endothelial cell permeability via the tyrosine phosphorylation of VE-cadherin. AB - Migration of monocytes into the subendothelial layer of the intima is one of the critical events in early atherosclerosis. Chlamydia pneumoniae (C. pneumoniae) infection has been shown to promote monocyte transendothelial migration (TEM). However, the exact mechanisms have not yet been fully clarified. In this study, we tested the hypothesis that C. pneumoniae infection increases vascular endothelial cell (VEC) permeability and subsequent monocyte TEM through stimulating the tyrosine phosphorylation of vascular endothelial-cadherin (VE cadherin). Here, we demonstrated that C. pneumoniae infection promoted monocyte TEM in a TEM assay possibly by increasing the permeability of a VEC line EA.hy926 cell as assessed by measuring the passage of FITC-BSA across a VEC monolayer. Subsequently, Western blot analysis showed that C. pneumoniae infection induced VE-cadherin internalization. Our further data revealed that Src-mediated VE cadherin phosphorylation at Tyr658 was involved in C. pneumoniae infection induced internalization of VE-cadherin, VEC hyperpermeability and monocyte TEM. Taken together, our data indicate that C. pneumoniae infection promotes monocyte TEM by increasing VEC permeability via the tyrosine phosphorylation and internalization of VE-cadherin in VECs. PMID- 29462614 TI - TGF-beta1/TbetaRII/Smad3 signaling pathway promotes VEGF expression in oral squamous cell carcinoma tumor-associated macrophages. AB - Oral squamous cell carcinoma (OSCC) is the most common type of malignant cancer affecting the oral cavity. Tumor associated macrophages (TAMs) play a vital role in the initiation, progression and metastasis of OSCC. In this study, we investigated the correlation between macrophages and several clinical and pathological indicators, and we also explored how transforming growth factor beta1 (TGF-beta1) effect on VEGF expression in TAMs. Seventy-two paraffin embedded OSCC samples were collected. Association between macrophages density, micro vascular density (MVD) and clinical-pathological feature were explored by immunohistochemical staining. Western blot, ELISA and qRT-PCR were conducted to assess the VEGF expression in TAMs treated with or without neutralizing TGF beta1, TbetaRII and smad3 antibodies. Results showed that CD68+ macrophages were absent in normal tissues. Macrophages density was directly correlated to low pathological differentiation, late clinical staging and poor survival rate. MVD showed positive correlation with clinical staging and macrophages density. Furthermore, OSCC-associated macrophages expressed more VEGF than macrophages in healthy lymph nodes. However, when TGF-beta1 or TbetaRII were neutralized or the Smad3 was inhibited, VEGF expression was down regulated as well. It is concluded that TGF-beta1 could promote OSCC-associated macrophages to secrete more VEGF via TbetaRII/Smad3 signaling pathway. This result might explain the correlation between macrophages density and worse clinical-pathological condition. PMID- 29462615 TI - Ubiquitin C-Terminal Hydrolase L1 regulates autophagy by inhibiting autophagosome formation through its deubiquitinating enzyme activity. AB - Ubiquitination modification has been shown to play a key role in autophagy. Increasing studies reported the involvement of de-ubiquitinating enzymes (DUBs) in autophagy pathway. To systematically search how DUBs manipulate autophagy, we utilized a double fluorescence tagged LC3 stable HeLa cell line, and did a genome wide screen of 55 human DUBs which is about 60% coverage of the DUB family. We found a bunch of DUBs have impact on autophagy by either changing the LC3 puncta formation or the autophagy flux. One of them, Ubiquitin C-Terminal Hydrolase L1 (UCHL1) correlated to Parkinson's disease, strongly affects autophagy by inhibiting autophagosome formation. We found UCHL1 overexpression inhibits LC3 puncta formation and is dependent on its DUB activity. Knockdown of UCHL1 significantly promotes LC3 puncta formation. Further study revealed that UCHL1 may affect autophagy by interacting with LC3 but not other autophagy related proteins. Interestingly, a Parkinson's disease related mutant UCHL1 I93 M defects its DUB activity and can no longer inhibit autophagosome formation. We further screened 22 commercially available DUB inhibitors and found two potent UCHL1 inhibitors LDN-57444 (LDN) and NSC632839 (NSC), when treating cells, both strongly induce LC3 puncta formation. Taken together, our results indicated a new insight into the manner in which DUB regulates autophagy and provided potential drugs for the Parkinson's disease. PMID- 29462616 TI - A potential substrate binding pocket of BdcA plays a critical role in NADPH recognition and biofilm dispersal. AB - Biofilm dispersal is characterized by the cell detachment from biofilms and expected to provide novel "anti-biofilm" approaches of prevention and treatment of biofilms in clinical and industrial settings. The E.coli protein BdcA has been identified as a biofilm dispersal factor and designed to be an important component in engineered applications to control biofilm formation. It belongs to short-chain dehydrogenase/reductase (SDR) family with the specific affinity to NADPH. Here, we show the structure of BdcA in complex with NADPH and confirm that NADPH binding is requisite for BdcA facilitating cell motility and increasing biofilm dispersal. Especially, we observe a potential substrate binding pocket surrounded by hydrophobic residues upon NADPH binding and present evidences that this pocket is essential for BdcA binding NADPH and exerting its biological functions. Our study provides the clues for illuminating the molecular mechanism of BdcA regulating biofilm dispersal and better utilizing BdcA to eliminate the biofilms. PMID- 29462618 TI - Overexpression of Larp4B downregulates dMyc and reduces cell and organ sizes in Drosophila. AB - Regulation of cell and organ sizes is fundamental for all organisms, but its molecular basis is not fully understood. Here we performed a gain-of-function screen and identified larp4B whose overexpression reduces cell and organ sizes in Drosophila melanogaster. Larp4B is a member of La-related proteins (LARPs) containing an LA motif and an adjacent RNA recognition motif (RRM), and play diverse roles in RNA metabolism. However, the function of Larp4B has remained poorly characterized. We generated transgenic flies overexpressing wild-type Larp4B or a deletion variant lacking the LA and RRM domains, and demonstrated that the RNA-binding domains are essential for Larp4B to reduce cell and organ sizes. We found that the larp4B-induced phenotype was suppressed by dMyc overexpression, which promotes cell growth and survival. Furthermore, overexpression of larp4B decreased dMyc protein levels, whereas its loss-of function mutation had an opposite effect. Our results suggest that Larp4B is a negative regulator of dMyc. PMID- 29462617 TI - Effect of trichostatin A on Burkitt's lymphoma cells: Inhibition of EPS8 activity through Phospho-Erk1/2 pathway. AB - Histone deacetylase inhibitors (HDACi) manifest great potential for treatment of Burkitt's lymphoma (BL), an aggressive B-cell lymphoma. Epidermal growth factor receptor pathway substrate 8 (EPS8) is confirmed overexpressed and associated with poor prognosis in solid tumors and leukemia. However, EPS8 expression and the relationship between EPS8 and HDACi on BL remains obscure. Here, we hypothesized that trichostatin A (TSA), a pan-HDACi, could inhibit BL cells by downregulating EPS8. We demonstrated that TSA reduced cell viability, induced apoptosis and cell arrest at G0/G1. Mechanismly, TSA attenuated EPS8 and downstream Phospho-Erk1/2 pathway. Knockdown of EPS8 resulted in a significant reduction in cellular proliferation and suppressed Phospho-Erk1/2 pathway activity, particularly when combined with TSA. Conversely, overexpression of EPS8 rescued this phenomenon. Then we showed that the combination of TSA and Epirubicin had a more significant effect when compared with TSA or Epirubicin alone. Finally, knockdown of EPS8 and TSA had a synergistic suppression effect on BALB/c nude mice. In conclusion, this study reveals that TSA affects BL cells by suppressing Phospho-Erk1/2 pathway through downregulating EPS8. PMID- 29462619 TI - Soluble dietary fiber improves energy homeostasis in obese mice by remodeling the gut microbiota. AB - Intervention with dietary fibers is an important strategy to combat the global epidemic of obesity which is a consequence of energy imbalance. However, a possible role of the gut microbiota in effects of dietary fibers on energy homeostasis remains unclear. Here, we treated a high fat diet-induced obese (DIO) mouse model with soluble dietary fiber. Our results showed that soluble dietary fiber reduced body weight gain and the excessive accumulation of white fat tissue in DIO mice. Notably, soluble dietary fiber increased energy expenditure, but not change energy intake in DIO mice. In accordance, 16S rRNA sequencing revealed that the diversity of the gut microbiota was restored by soluble dietary fiber. Moreover, compared with controls, soluble dietary fiber resulted in a decreased ratio of Firmicutes/Bacteroidetes at the phylum level, and an increased relative abundance of the genera Roseburia at the genus level. Taken together, these findings indicate that soluble dietary fiber improves energy homeostasis and prevents obesity by increasing the diversity of the gut microbiota and the colonization of beneficial bacteria. PMID- 29462620 TI - Human AK2 links intracellular bioenergetic redistribution to the fate of hematopoietic progenitors. AB - AK2 is an adenylate phosphotransferase that localizes at the intermembrane spaces of the mitochondria, and its mutations cause a severe combined immunodeficiency with neutrophil maturation arrest named reticular dysgenesis (RD). Although the dysfunction of hematopoietic stem cells (HSCs) has been implicated, earlier developmental events that affect the fate of HSCs and/or hematopoietic progenitors have not been reported. Here, we used RD-patient-derived induced pluripotent stem cells (iPSCs) as a model of AK2-deficient human cells. Hematopoietic differentiation from RD-iPSCs was profoundly impaired. RD-iPSC derived hemoangiogenic progenitor cells (HAPCs) showed decreased ATP distribution in the nucleus and altered global transcriptional profiles. Thus, AK2 has a stage specific role in maintaining the ATP supply to the nucleus during hematopoietic differentiation, which affects the transcriptional profiles necessary for controlling the fate of multipotential HAPCs. Our data suggest that maintaining the appropriate energy level of each organelle by the intracellular redistribution of ATP is important for controlling the fate of progenitor cells. PMID- 29462621 TI - Direct posttranslational modification of astrocytic connexin 43 proteins by the general anesthetic propofol in the cerebral cortex. AB - Propofol is widely used as a general anesthetic and is generally considered to exert its action by regulating neuronal firing via facilitation of GABAA receptors. However, accumulating evidence suggests that propofol also acts on astrocytes, including inhibitory effects on gap junctional coupling, but the underlying molecular mechanisms remain largely unknown. Here, using acute cortical brain slices prepared from mice, we characterize propofol-induced molecular changes in astrocytic gap junction protein connexin 43 (Cx43). Propofol does not change the protein expression level of Cx43 or its incorporation into gap junctional plaques, according to biochemical and immunohistochemical analyses. However, propofol alters migration pattern of Cx43 on western blot, suggesting changes in its posttranslational modifications. Indeed, this change is accompanied by an increase in the phosphorylation of Cx43 at serine 368, which is known to reduce permeability of Cx43 gap junctions. Finally, we show that this change occurs in the absence of neuronal firing or glutamatergic transmissions. Overall, these results show that propofol induces posttranslational modification of Cx43 directly on astrocytes at the site of gap junctional plaques, exerting direct pharmacological action on astrocytes in parallel with its action on neurons. PMID- 29462622 TI - Additional increased effects of mannitol-temozolomide combined treatment on blood brain barrier permeability. AB - The blood-brain barrier (BBB) is major obstacle in drug or stem cell treatment in chronic stroke. We hypothesized that adding mannitol to temozolomide (TMZ) is a practically applicable method for resolving the low efficacy of intravenous mannitol therapy. In this study, we investigated whether BBB permeability could be increased by this combined treatment. First, we established a chronic ischemic stroke rat model and examined changes in leakage of Evans blue dye within a lesion site, and in expression of tight junction proteins (TJPs), by this combined treatment. Additionally, in an in vitro BBB model using trans-wells, we analyzed changes in diffusion of a fluorescent tracer and in expression of TJPs. Mannitol-TMZ combined treatment not only increased the amount of Evans blue dye within the stroke lesion site, but also reduced occludin expression in rat brain microvessels. The in vitro study also showed that combined treatment increased the permeability for two different-sized fluorescent tracers, especially large size, and decreased expression of TJPs, such as occludin and ZO-1. Increased BBB permeability effects were more prominent with combined than with single treatments. Mannitol-TMZ combined treatment induced a decrease of TJPs with a consequent increase in BBB permeability. This combined treatment is clinically useful and might provide new therapeutic options by enabling efficient intracerebral delivery of various drugs that could not otherwise be used to treat many CNS diseases due to their inability to penetrate the BBB. PMID- 29462623 TI - Identification of matrix metalloproteinase 9-interacting sequences in staphylococcal superantigen-like protein 5. AB - Staphylococcal superantigen like 5 (SSL5) is an exotoxin produced by S. aureus and has a strong inhibitory effect on MMP-9 enzymatic activity. However, the mechanism of inhibition remains unclear. We sought to identify the responsible regions of SSL5 for the interaction with MMP-9 by comparing a series of domain swap and deletion mutants of SSL5. Binding analyses revealed that SSL5 had two regions for binding to MMP-9 catalytic domain, beta1-3 region (25SKELKNVTGY RYSKGGKHYL IFDKNRKFTR VQIFGK60) in N-terminal half and alpha4beta9 region (138KELDFKLRQY LIQNFDLYKK FPKDSKIKVI MKD170) in C-terminal half. The collagen binding domain and zinc-chelating histidine residues of MMP-9 were not essential for the specific binding to SSL5. The domain swap mutants of SSL5 that conserved beta1-3 but not alpha4beta9 region inhibited the gelatinolysis by MMP-9, and the mutant of SSL7 that substituted beta1-3 region to that of SSL5 acquired the binding and inhibitory activity. Furthermore, the polypeptide that harbored beta1 3 region of SSL5 inhibited gelatinolysis by MMP-9. Taken together, SSL5 inhibits the MMP9 activity through binding to the catalytic domain, and the beta1-3 region is responsible for the inhibition of proteolytic activity of MMP-9. PMID- 29462624 TI - Human sperm swimming in a high viscosity mucus analogue. AB - Remarkably, mammalian sperm maintain a substantive proportion of their progressive swimming speed within highly viscous fluids, including those of the female reproductive tract. Here, we analyse the digital microscopy of a human sperm swimming in a highly viscous, weakly elastic mucus analogue. We exploit principal component analysis to simplify its flagellar beat pattern, from which boundary element calculations are used to determine the time-dependent flow field around the sperm cell. The sperm flow field is further approximated in terms of regularised point forces, and estimates of the mechanical power consumption are determined, for comparison with analogous low viscosity media studies. This highlights extensive differences in the structure of the flows surrounding human sperm in different media, indicating how the cell-cell and cell-boundary hydrodynamic interactions significantly differ with the physical microenvironment. The regularised point force decomposition also provides cell level information that may ultimately be incorporated into sperm population models. We further observe indications that the core feature in explaining the effectiveness of sperm swimming in high viscosity media is the loss of cell yawing, which is related with a greater density of regularised point force singularities along the axis of symmetry of the flagellar beat to represent the flow field. In turn this implicates a reduction of the wavelength of the distal beat pattern - and hence dynamical wavelength selection of the flagellar beat - as the dominant feature governing the effectiveness of sperm swimming in highly viscous media. PMID- 29462625 TI - Enhanced prediction of recombination hotspots using input features extracted by class specific autoencoders. AB - In yeast and in some mammals the frequencies of recombination are high in some genomic locations which are known as recombination hotspots and in the locations where the recombination is below average are consequently known as coldspots. Knowledge of the hotspot regions gives clues about understanding the meiotic process and also in understanding the possible effects of sequence variation in these regions. Moreover, accurate information about the hotspot and coldspot regions can reveal insights into the genome evolution. In the present work, we have used class specific autoencoders for feature extraction and reduction. Subsequently the deep features that are extracted from the autoencoders were used to train three different classifiers, namely: gradient boosting machines, random forest and deep learning neural networks for predicting the hotspot and coldspot regions. A comparative performance analysis was carried out by experimenting on deep features extracted from different sets of the training data using autoencoders for selecting the best set of deep features. It was observed that learning algorithms trained on features extracted from the combined class specific autoencoder out performed when compared with the performances of these learning algorithms trained with other sets of deep features. So the combined class-specific autoencoder based feature extraction can be applied to a growing range of biological problems to achieve superior prediction performance. PMID- 29462626 TI - An approach for reduction of false predictions in reverse engineering of gene regulatory networks. AB - A gene regulatory network discloses the regulatory interactions amongst genes, at a particular condition of the human body. The accurate reconstruction of such networks from time-series genetic expression data using computational tools offers a stiff challenge for contemporary computer scientists. This is crucial to facilitate the understanding of the proper functioning of a living organism. Unfortunately, the computational methods produce many false predictions along with the correct predictions, which is unwanted. Investigations in the domain focus on the identification of as many correct regulations as possible in the reverse engineering of gene regulatory networks to make it more reliable and biologically relevant. One way to achieve this is to reduce the number of incorrect predictions in the reconstructed networks. In the present investigation, we have proposed a novel scheme to decrease the number of false predictions by suitably combining several metaheuristic techniques. We have implemented the same using a dataset ensemble approach (i.e. combining multiple datasets) also. We have employed the proposed methodology on real-world experimental datasets of the SOS DNA Repair network of Escherichia coli and the IMRA network of Saccharomyces cerevisiae. Subsequently, we have experimented upon somewhat larger, in silico networks, namely, DREAM3 and DREAM4 Challenge networks, and 15-gene and 20-gene networks extracted from the GeneNetWeaver database. To study the effect of multiple datasets on the quality of the inferred networks, we have used four datasets in each experiment. The obtained results are encouraging enough as the proposed methodology can reduce the number of false predictions significantly, without using any supplementary prior biological information for larger gene regulatory networks. It is also observed that if a small amount of prior biological information is incorporated here, the results improve further w.r.t. the prediction of true positives. PMID- 29462627 TI - Embeddability of Kimura 3ST Markov matrices. AB - In this note, we characterize the embeddability of generic Kimura 3ST Markov matrices in terms of their eigenvalues. As a consequence, we are able to compute the volume of such matrices relative to the volume of all Markov matrices within the model. We also provide examples showing that, in general, mutation rates are not identifiable from substitution probabilities. These examples also illustrate that symmetries between mutation probabilities do not necessarily arise from symmetries between the corresponding mutation rates. PMID- 29462628 TI - Term small-for-gestational-age infants from low-risk women are at significantly greater risk of adverse neonatal outcomes. AB - BACKGROUND: Small-for-gestational-age infants (birthweight <0th centile) are at increased risk of perinatal complications but are frequently not identified antenatally, particularly in low-risk women delivering at term (>=37 weeks gestation). This is compounded by the fact that late pregnancy ultrasound is not the norm in many jurisdictions for this cohort of women. We thus investigated the relationship between birthweight <10th centile and serious neonatal outcomes in low-risk women at term. OBJECTIVE(S): We aimed to determine whether there is a difference of obstetric and perinatal outcomes for small-for-gestational-age infants, subdivided into fifth to <10th centile and less than the fifth centile cohorts compared with an appropriate-for-gestational age (birthweight 10th-90th centile) group at term. STUDY DESIGN: This was a retrospective analysis of data from the Mater Mother's Hospital in Brisbane, Australia, for women who delivered between January 2000 and December 2015. Women with multiple pregnancy, diabetes mellitus, hypertension, preterm birth, major congenital anomalies, and large for gestational age infants (>90th centile for gestational age) were excluded. Small for-gestational-age infants were subdivided into 2 cohorts: infants with birthweights from the fifth to <10th centile and those less than the fifth centile. Serious composite neonatal morbidity was defined as any of the following: Apgar score <=3 at 5 minutes, respiratory distress syndrome, acidosis, admission into the neonatal intensive care unit, stillbirth, or neonatal death. Univariate and multivariate analyses were performed using generalized estimating equations to compare obstetric and perinatal outcomes for small-for-gestational age infants compared with appropriate-for-gestational age controls. RESULTS: The final study comprised 95,900 infants. Five percent were between the fifth and <10th centiles for birthweight and 4.3% were less than the fifth centile. The rate of serious composite neonatal morbidity was 11.1% in the control group, 13.7% in the fifth and <10th centile, and 22.6% in the less than the fifth centile cohorts, respectively. Even after controlling for confounders, both the fifth to <10th centiles and less than the fifth centile cohorts were at significantly increased risk of serious composite neonatal morbidity compared with controls (odds ratio, 1.25, 95% confidence interval, 1.15-1.37, and odds ratio, 2.20, 95% confidence interval, 2.03-2.39, respectively). Infants with birthweights <10th centile were more likely to have severe acidosis at birth, 5 minute Apgar score <=3 and to be admitted to the neonatal intensive care unit. The serious composite neonatal morbidity was higher in infants less than the fifth centile compared with those in the fifth to <10th centile cohort (odds ratio, 1.71, 95% confidence interval, 1.52-1.92). The odds of perinatal death (stillbirth and neonatal death) were significantly higher in both small-for gestational age groups than controls. After stratification for gestational age at birth, the composite outcome remained significantly higher in both small-for gestational-age cohorts and was highest in the less than the fifth centile group at 37+0 to 38+6 weeks (odds ratio, 3.32, 95% confidence interval, 2.87-3.85). The risk of perinatal death was highest for infants less than the fifth centile at 37+0 to 38+6 weeks (odds ratio, 5.50, 95% confidence interval, 2.33-12.98). CONCLUSION: Small-for-gestational-age infants from term, low-risk pregnancies are at significantly increased risk of mortality and morbidity when compared with appropriate-for-gestational age infants. Although this risk is increased at all gestational ages in infants less than the fifth centile for birthweight, it is highest at early-term gestation. Our findings highlight that early-term birth does not necessarily improve outcomes and emphasize the importance of identifying this cohort of infants. PMID- 29462629 TI - A prospective study of risk-based colposcopy demonstrates improved detection of cervical precancers. AB - BACKGROUND: Sensitivity for detection of precancers at colposcopy and reassurance provided by a negative colposcopy are in need of systematic study and improvement. OBJECTIVE: We sought to evaluate whether selecting the appropriate women for multiple targeted cervical biopsies based on screening cytology, human papillomavirus testing, and colposcopic impression could improve accuracy and efficiency of cervical precancer detection. STUDY DESIGN: In all, 690 women aged 18-67 years referred to colposcopy subsequent to abnormal cervical cancer screening results were included in the study (ClinicalTrials.gov: NCT00339989). Up to 4 cervical biopsies were taken during colposcopy to evaluate the incremental benefit of multiple biopsies. Cervical cytology, human papillomavirus genotyping, and colposcopy impression were used to establish up to 24 different risk strata. Outcomes for the primary analysis were cervical precancers, which included p16+ cervical intraepithelial neoplasia 2 and all cervical intraepithelial neoplasia 3 that were detected by colposcopy-guided biopsy during the colposcopy visit. Later outcomes in women without cervical intraepithelial neoplasia 2+ at baseline were abstracted from electronic medical records. RESULTS: The risk of detecting precancer ranged from 2-82% across 24 strata based on colposcopy impression, cytology, and human papillomavirus genotyping. The risk of precancer in the lowest stratum increased only marginally with multiple biopsies. Women in the highest-risk strata had risks of precancer consistent with immediate treatment. In other risk strata, multiple biopsies substantially improved detection of cervical precancer. Among 361 women with cervical intraepithelial neoplasia <2 at baseline, 195 (54%) had follow-up cytology or histology data with a median follow-up time of 508 days. Lack of detection of precancer at initial colposcopy that included multiple biopsies predicted low risk of precancer during follow-up. CONCLUSION: Risk assessment at the colposcopy visit makes identification of cervical precancers more effective and efficient. Not finding precancer after a multiple-biopsy protocol provides high reassurance and allows releasing women back to regular screening. PMID- 29462630 TI - Pitfalls in assessing chorioamnionicity: novel observations and literature review. AB - Accurate diagnosis of chorioamnionicity in multiple pregnancies is the key to appropriate clinical management of multiple gestation. Although prenatal ultrasound assessment of chorioamnionicity is well established and highly accurate if performed in early pregnancy, exceptions and artifacts arise from anatomic variations in multiple pregnancies and unusual sonographic features do exist. We have summarized our own experiences and reports from the literature on these pitfalls as follows: (1) discordant fetal sex in monochorionic pregnancies due to sex chromosome abnormalities, genital malformation in 1 fetus, or dizygotic twins forming a monochorionic placenta; (2) separate placental masses in monochorionic pregnancies due to bipartite placenta; (3) false-negative and false-positive lambda sign can arise for various reasons, and in partial monochorionic/dichorionic placentas both T and lambda sign may co-exist; (4) intrauterine synechia appearing as a thick and echogenic intrauterine septum may lead to erroneous diagnosis of dichorionic twins; and (5) errors in ascertaining amnionicity by the visualization of thin intertwin amniotic membranes and the number of yolk sacs. The ultrasound techniques to reduce inaccuracy in prenatal determination of chorioamnionicity and the use of single nucleotide polymorphisms based on noninvasive prenatal test to determine zygosity are also reviewed. PMID- 29462631 TI - Rapidly Dissolving Microneedle Patches for Transdermal Iron Replenishment Therapy. AB - The prevalence of iron deficiency anemia (IDA) is predominant in women and children especially in developing countries. The disorder affects cognitive functions and physical activity. Although oral iron supplementation and parenteral therapy remains the preferred choice of treatment, gastric side effects and risk of iron overload decreases adherence to therapy. Transdermal route is an established approach, which circumvents the side effects associated with conventional therapy. In this project, an attempt was made to investigate the use of rapidly dissolving microneedles loaded with ferric pyrophosphate (FPP) as a potential therapeutic approach for management of IDA. Microneedle array patches were made using the micromolding technique and tested in vitro using rat skin to check the duration required for dissolution/disappearance of needles. The ability of FPP-loaded microneedles to replenish iron was investigated in anemic rats. Rats were fed iron-deficient diet for 5 weeks to induce IDA following which microneedle treatment was initiated. Recovery of rats from anemic state was monitored by measuring hematological and biochemical parameters. Results from in vivo study displayed significant improvements in hemoglobin and serum iron levels after 2-week treatment with FPP-loaded microneedles. The study effectively demonstrated the potential of microneedle-mediated iron replenishment for treatment of IDA. PMID- 29462632 TI - Water Activity and Its Significance in Topical Dosage Forms. AB - Unique properties of thermodynamic activity of solvents in topical semisolids and its effects on in vitro product performance have not been fully understood. Mechanistic investigation was undertaken to demonstrate the significance of thermodynamic potential of solvents [water activity (aw) or solvent activity (as)] on in vitro performance of model topical formulations. Drug transport across synthetic membranes was found to decrease with decreasing water activity of formulations. Similarly, in vitro permeation of model permeant (caffeine) across porcine epidermis was found to decrease with decreasing water activity of formulations. Notably, relatively low water activity formulations (aw, 0.78) induced dehydration in porcine skin associated with significant structural changes like detachment of individual stratum corneum layers. Inclusion of hydrating agents (propylene glycol) in low water activity (aw, 0.78) formulations restored hydration levels and structural integrity of porcine skin. Most importantly, incremental inclusion of propylene glycol in low water activity formulations (aw, 0.78) enhanced in vitro permeation of model permeant (fluorescein sodium). Further investigation revealed that variability in processing conditions (high shear mixing during emulsification step) could modulate water activity in semisolid formulations despite their compositional sameness. In retrospect, water activity was found to be a critical quality attribute of topical semisolid products which impacts overall product performance and drug delivery. PMID- 29462633 TI - Improved Stability of Tuberculosis Drug Fixed-Dose Combination Using Isoniazid Caffeic Acid and Vanillic Acid Cocrystal. AB - The classic fixed-dose combination (FDC) of 4 tuberculosis drugs, namely rifampicin (RIF), isoniazid (INH), pyrazinamide (PZA), and ethambutol dihydrochloride (EDH) has the twin issues of physical stability and RIF cross reaction in the 4-FDC. The major reason for these quality issues is the interaction between RIF and INH to yield isonicotinyl hydrazone in drug tablets. Pharmaceutical cocrystals of INH with caffeic acid (CFA) (PZA + EDH + RIF + INH CFA cocrystal) and vanillic acid (VLA) (PZA + EDH + RIF + INH-VLA cocrystal) are able to stabilize the FDC formulation compared with the reference batch (PZA + EDH + RIF + INH). Stability studies under accelerated humidity and temperature stress conditions of 40 degrees C and 75% relative humidity showed that the physical stability of the cocrystal formulation was superior by powder X-ray diffraction and scanning electron microscopy analysis, and chemical purity was analyzed by high-performance liquid chromatography. Changes in the composition and structure were monitored on samples drawn at 7, 15, 22, and 30 days of storage. FDC-INH-CFA cocrystal batch exhibited greater stability compared with FDC-INH-VLA cocrystal and FDC reference drug batches. The superior stability of INH-CFA cocrystal is attributed to the presence of stronger hydrogen bonds and cyclic O-H?O synthon in the crystal structure. PMID- 29462634 TI - Labrasol(r) and Salts of Medium-Chain Fatty Acids Can Be Combined in Low Concentrations to Increase the Permeability of a Macromolecule Marker Across Isolated Rat Intestinal Mucosae. AB - In addition to their solubilizing properties, excipients used in lipid-based formulations can improve intestinal permeability of macromolecules. We determined whether admixing of medium-chain fatty acid (MCFA) permeation enhancers with a lipoidal excipient (Labrasol(r)) could potentiate transepithelial flux of a poorly permeable macromolecule (fluorescein isothiocyanate dextran 4 kDa [FD4]) across rat intestinal mucosae mounted in Ussing chambers. Low concentrations of sodium caprate (C10), sodium undecylenate (C11:1), or sodium laurate (C12) combined with Labrasol(r) increased the apparent permeability coefficient (Papp) of FD4 to values typically seen with higher concentrations of MCFAs or Labrasol(r) alone. For example, combination of C11:1 (0.5 mg/mL) with Labrasol(r) (1 mg/mL) increased the Papp of FD4 by 10- and 11-fold over the respective individual agents at the same concentrations where no enhancement was evident. The increased enhancement ratios seen with the combinations were associated with some perturbation in intestinal histology and with attenuation of an epithelial functional measure, carbachol-stimulated inward short-circuit current. In conclusion, combining three MCFAs separately with Labrasol(r) increased the Papp of FD4 to values greater than those seen for MCFAs or Labrasol(r) alone. Ultimately, this may permit lower concentrations of MCFA to be used in combination with other excipients in oral formulations of poorly permeable molecules.

AB - Betulinic acid (BA), a plant-derived pentacyclic triterpenoid, may interact with the members of the organic anion transporting polypeptide 1B subfamily. Here, we investigated the interactions of BA and its analogs with OATP1B1/3 and rat Oatp1b2 in vitro and in vivo. BA inhibited the activity of OATP1B1/3 and rat Oatp1b2 in vitro. Systemic exposure of atorvastatin was substantially altered with the intravenous co-administration of BA (20 mg/kg). Preincubation (incubation with inhibitors, followed by washout) with BA led to a sustained inhibition of OATP1B3, which recovered rapidly in the media containing 10% fetal bovine serum. The addition of albumin to the media decreased intracellular concentrations of BA and expedited the recovery of OATP1B3 activity following preincubation. For asunaprevir and cyclosporin A (previously known to inhibit OATP1B3 upon preincubation), the addition of albumin to the media shortened recovery time with asunaprevir, but not with cyclosporin A. Overall, our results showed that BA inhibits OATP1B transporters in vitro and may incur hepatic transporter-mediated drug interactions in vivo. Our results identify BA as another OATP1B3 inhibitor with preincubation effect and suggest that the preincubation effect and its duration is impacted by altered equilibrium of inhibitors between intracellular and extracellular space (e.g., albumin in the media).

AB - The liver exhibits intrinsic immune tolerogenic properties that contribute to a unique propensity toward spontaneous acceptance when transplanted, both in animal models and in humans. Thus, in contrast to what happens after transplantation of other solid organs, several years following liver transplantation a significant subset of patients are capable of maintaining normal allograft function with histological integrity in the absence of immunosuppressive drug treatment. Significant efforts have been put into identifying sensitive and specific biomarkers of tolerance in order to stratify liver transplant recipients according to their need for immunosuppressive medication and their likelihood of being able to completely discontinue it. These biomarkers are currently being validated in prospective clinical trials of immunosuppression withdrawal both in Europe and in the United States. These studies have the potential to transform the clinical management of liver transplant recipients by mitigating, at least in part, the burden of lifelong immunosuppression.

AB - The present study demonstrates that docosahexaenoic acid (DHA, 22:6n-3) injected subcutaneously leads to recovery of locomotor functions observed within 5 weeks after traumatic spinal cord injury. This activity is confirmed by improving of BBB locomotor rating scale indicators. We assume that this activity is related to (1) enhancement of remyelination process, (2) proliferative activity, (3) antioxidant activity, (4) increase in GFAP staining and (5) enhancement of vimentin expression. In general, the results of the study show that DHA has a complex effect on post-traumatic central nervous system recovery, indicating its high therapeutic potential. PMID- 29462639 TI - Inhibition or facilitation? Modulation of corticospinal excitability during motor imagery. AB - Motor imagery (MI) is the mental simulation of an action without any overt movement. Functional evidences show that brain activity during MI and motor execution (ME) largely overlaps. However, the role of the primary motor cortex (M1) during MI is controversial. Effective connectivity techniques show a facilitation on M1 during ME and an inhibition during MI, depending on whether an action should be performed or suppressed. Conversely, Transcranial Magnetic Stimulation (TMS) studies report facilitatory effects during both ME and MI. The present TMS study shed light on MI mechanisms, by manipulating the instructions given to the participants. In both Experimental and Control groups, participants were asked to mentally simulate a finger-thumb opposition task, but only the Experimental group received the explicit instruction to avoid any unwanted fingers movements. The amplitude of motor evoked potentials (MEPs) to TMS during MI was compared between the two groups. If the M1 facilitation actually pertains to MI per se, we should have expected to find it, irrespective of the instructions. Contrariwise, we found opposite results, showing facilitatory effects (increased MEPs amplitude) in the Control group and inhibitory effects (decreased MEPs amplitude) in the Experimental group. Control experiments demonstrated that the inhibitory effect was specific for the M1 contralateral to the hand performing the MI task and that the given instructions did not compromise the subjects' MI abilities. The present findings suggest a crucial role of motor inhibition when a "pure" MI task is performed and the subjects are explicitly instructed to avoid overt movements.

AB - OBJECTIVE: To summarize all current studies focusing on blood biomarkers in paediatric mild traumatic brain injury (mTBI) and to outline the possible use of blood biomarkers for diagnostic, prognostic and monitoring purposes within this setting. METHODS: A systematic review following the PRISMA guidelines was conducted using the MEDLINE, PubMed and EMBASE databases. RESULTS: A total of 21 studies were included in the review, encompassing a total of 14 different biomarkers. Seventeen (81%) of these studies found a significant association between biomarker concentration and mTBI characteristics, however results from studies to date are diverse and at times conflicting. CONCLUSION: GFAP appears to be a promising blood biomarker for the prognosis and monitoring of mTBI, whereas UCH-L1 appears more promising at mTBI diagnosis. Despite this, the overall heterogeneity in assessed biomarkers, study design and measurement tools has made drawing specific conclusions challenging. Future research will require more uniform study design and methodological approaches to allow for the comparison, corroboration and validation of blood biomarkers within the context of paediatric mTBI. PMID- 29462641 TI - Predicting neurodevelopmental outcome in preterm born infants using auditory event-related potentials: A systematic review. AB - Prematurity is a known risk factor for later cognitive deficits. At present there are neither behavioral nor neurological tests available to detect those preterm infants who would benefit most from early interventions. Neurophysiologic methods, and more specifically, auditory event-related potentials (AERPs) are convenient tools to investigate early cognitive functioning. However, the capability of AERPs as a prognostic factor for mental development in preterm infants remains unclear. The present systematic search of the literature yielded 1016 articles, out of which 13 were included. Both prospective and cross sectional studies reported a relationship between AERPs and cognitive outcome. Our results show that larger amplitudes and shorter latencies of late AERPs are related to better cognitive outcomes. Additional studies are needed to corroborate our findings regarding this potential use of AERPs in the individual evaluation of preterm born infants. PMID- 29462642 TI - Memory performance, global cerebral volumes and hippocampal subfield volumes in long-term survivors of Out-of-Hospital Cardiac Arrest. AB - AIM: We explored the associations between global brain volumes, hippocampal subfield volumes and verbal memory performance in long-term survivors of out-of hospital cardiac arrest (OHCA). METHODS: Three months after OHCA, survivors and healthy, age-matched controls were assessed with cerebral MRI and the California Verbal Learning Test-II (CVLT-II). Volumetric brain segmentation was performed automatically by FreeSurfer. RESULTS: Twenty-six OHCA survivors who were living independently in regular homes at the time of assessment and 19 controls participated in the study. Thirteen of the survivors had been conscious upon arrival to the emergency department. The other 13 survivors had 0.5-7 days of inpatient coma before recovery. Memory was poorer in the OHCA group that had been comatose beyond initial hospital admission compared to both other groups. Total cortical volumes, total hippocampus volumes and several hippocampal subfield volumes were significantly smaller in the OHCA group comatose beyond initial hospital admission compared to controls. No significant differences between the OHCA group conscious upon emergency department arrival and the other two groups were found for brain volumes. No significant differences were observed between any groups for white matter or total subcortical volumes. In OHCA survivors with recovery from inpatient coma, the various CVLT-II trials were significantly, but differentially, correlated to total gray matter volume, cortical volume and the hippocampal subfield subiculum. CONCLUSION: In this small, single-site study, both hippocampal volume and cortical volume were smaller in good outcome OHCA survivors 3 months after resuscitation in comparison to healthy controls. Smaller cerebral volumes were correlated with poorer memory performance. PMID- 29462643 TI - Pirouetting pigs: A large non-primate animal model based on unilateral 6 hydroxydopamine lesioning of the nigrostriatal pathway. AB - INTRODUCTION: The rotating 6-hydroxydopamine (6-OHDA) rat model has long been important when developing new treatment strategies for Parkinson's disease (PD). Similar non-human primate models have been developed for translational research purposes as large animal models are required by regulatory bodies as an intermediate "phase 0" trial step. However, experimental research in non-human primates encounters several economical and regulatory issues, which may be avoided by the alternative use of pigs as a large animal model for experimental brain research. OBJECTIVE: The primary aim of this study was to examine if unilateral injections of 6-OHDA into the Gottingen minipig nigrostriatal pathway would lead to dopaminergic imbalance and rotational behavior similar to the 6 OHDA unilateral symptomatic model of PD created in other species. The secondary aim was to attempt to verify the rotational behavior as a parkinsonian symptom using subthalamic deep brain stimulation (STN-DBS) to minimize the elicited rotational pattern. MATERIALS AND METHODS: Using an MRI-based stereotactic procedure, ten female Gottingen minipigs were injected unilaterally with 6-OHDA in the nigrostriatal pathway. Postoperatively, an MRI was performed, and the animals were injected with amphetamine and apomorphine and observed for rotational behavior. After a survival period of three months the brains were removed and immunohistochemically stained for tyrosine hydroxylase (TH). One week before sacrifice two animals had DBS electrodes unilaterally implanted in the subthalamic nucleus and various stimulation protocols were conducted during amphetamine challenge. RESULTS: As expected most animals rotated towards the side of the lesion when given amphetamine (3.5-4.0 mg/kg), whereas the predicted opposite response to apomorphine were much harder to reproduce. T1- and T2 weighted postoperative MRI could demonstrate the size and the location of the 6 OHDA injection. Postmortem TH-staining of the final two animals receiving a medial and a lateral injection of 25 MUL of 6-OHDA (8 MUg/MUL, injection rate 5 MUL/min) into the diencephalic nigrostriatal pathway showed a prominent unilateral decrease in TH-staining of the substantia nigra pars compacta, the ventral tegmental area and the nigrostriatal pathway on the lesioned side. These two animals displayed spontaneous rotational behavior toward the lesioned side for the first 2-3 days postoperatively, and this behavior could later on be reelicited by amphetamine and attenuated by ipsilateral STN-DBS. CONCLUSION: Female Gottingen minipigs are susceptible to unilateral dopaminergic degeneration when properly injected unilaterally with sufficient amounts of 6-OHDA in the nigrostriatal pathway. The location of the 6-OHDA injections and thus the accuracy of the employed stereotaxy can be verified in vivo using MRI postoperatively. The injected minipigs display unilateral parkinsonism with a well-defined rotational response to amphetamine that may be ameliated by STN-DBS performed on the lesioned side. The response to apomorphine was, however, not consistent, illustrating that further work on this promising non-primate large animal model is needed, before it is fully similar to the established 6-OHDA models in other species.

AB - Chromobox protein homolog 3 (CBX3), a core component of the heterochromatin proteins 1, is recently proved to be involved in human cancerogenesis and associated with the prognosis of patient. However, the role of CBX3 in Tongue squamous cell carcinoma (TSCC) remains unclear. In the present study we found that CBX3 was upregulated in TSCC tissues when compared to adjacent non-tumor tissues, and multivariable analysis showed that high CBX3 expression was associated with clinical stage and cervical node metastasis, which was an independent prognostic indicator of TSCC. Furthermore, Kaplan-Meier survival analysis and log-rank test showed that TSCC patients with high CBX3 expression had a poorer rate of OS compared to patients with low CBX3 expression. Moreover, knocking down CBX3 inhibited TSCC cells proliferation both in vitro and in vivo, while overexpressing CBX3 promoted TSCC cells proliferation. In addition, CBX3 depletion resulted in cell cycle delay at the G1/S phase via the p21 pathway. In summary, we identifies CBX3 as a potential novel oncogene in TSCC, which may act as a biomarker and target in the diagnosis and treatment of this killer disease. PMID- 29462648 TI - Bovine viral diarrhea virus type 1 current taxonomy according to palindromic nucleotide substitutions method. AB - Pestivirus bovine viral diarrhea virus type 1 species is responsible for cosmopolitan diseases affecting cattle and other ruminants, presenting a wide range of clinical manifestations, with relevant impact on zootechnic production. Understanding genomic characteristic and virus taxonomy is fundamental in order to sustain control and prophylactic programs. Given the recent various studies reporting a relatively high number of new strains, in particular from Asian countries, in the present study, four hundred-eighty-two genomic sequences have been evaluated applying the palindromic nucleotide substitutions method for genotyping. Based on the secondary structure alignment and computing genetic distance among strains in the 5' untranslated region of Pestivirus RNA, the current taxonomy of the species was reviewed. Twenty-two genotypes have been identified, applying a nomenclature based on divergence in the genus.

AB - BACKGROUND: Rothmund-Thomson syndrome (RTS) is a rare autosomal recessive disorder mainly characterized by cutaneous poikiloderma, sparse hair, short stature and skeletal defects. Deleterious mutations in the RecQ-like DNA helicase type 4 (RECQL4) gene have been detected in approximately two-thirds of RTS cases. METHODS: Three Chinese patients from two unrelated families were enrolled for clinical evaluation. Targeted next-generation sequencing (NGS) using a custom panel consisting of 705 short-stature-related genes was performed for the probands. Variants detected by NGS were confirmed by Sanger sequencing and examined in family members. RESULTS: The probands presented with characteristic features of severe growth delay, poikiloderma mostly on the face, buttocks and extremities, sparse or absent hair, eyelashes, and eyebrows, forearm reduction defects, small hands with hypoplasia of the middle phalanx (little finger) in one of the probands, epicanthus, hypertelorism, and dental abnormalities. In addition, novel auricle features and other rare facial features, including narrow palpebral fissure, depressed nasal bridge, and small chin were exhibited. Four novel RECQL4 variants were identified, including three pathogenic frameshift variants, c.1724_1725delAC, p.His575fs*7; c.2421dupT, p.Asp808*; c.1770_1807del, p.Pro591fs*2, and one likely pathogenic missense variant, c.691G>A, p.Gly231Ser. CONCLUSION: Our study expands the mutational spectrum of RECQL4 gene and reveals novel phenotypes observed in Chinese RTS patients. PMID- 29462649 TI - The roles of the analogy with natural selection in B.F. Skinner's philosophy. AB - Beginning in the 1950s, B.F. Skinner made increasing reference to an analogy between operant conditioning and natural selection. This analogy is the basis of an argument that, in contrast to Skinner's other critiques of cognitive science, is neither epistemological nor pragmatic. Instead, it is based on the claim that ontogenetic adaptation is due to a special mode of causation he called "selection by consequences." He argued that this mode of causation conflicts with explanations that attribute action to an autonomous agent with reasons for acting. This argument dismisses ordinary explanations of action, and has implications not only for cognitive science but also for morals. Skinner cited the latter implications to counter objections to the application of behavior analysis to the reform of society and its institutions. Skinner's critique, however, rests upon empirical assumptions that have been criticized by other behavior analysts. Although for Skinner the major role of the analogy was to propose an empirical thesis, it also can play a metaphysical role-namely, to demonstrate the possibility of ontogenetic adaptation without reference to agents who have reasons for acting. These two roles, empirical and metaphysical, are the mirror image of the empirical and metaphysical roles of the computer analogy for cognitive science. That analogy also can be (and has been) interpreted as an empirical thesis. Its empirical implications, however, have been difficult to confirm. It also, however, has played a metaphysical role-namely, to demonstrate the possibility that a physical process could perform logical operations on states having propositional content. Neither analogy provides a well-confirmed, general answer to the question of how to explain the process of ontogenetic adaptation. But together they show there are two metaphysically coherent, but conflicting, answers to this question. Depending upon one's epistemology, the analogy with natural selection may provide a useful point of departure for a strategy of research. Such a pragmatic grounding for a research strategy does not, however, provide sufficient reason to abandon for purposes of ethics the concept of persons as autonomous agents. PMID- 29462650 TI - Song ontogeny in Nuttall's white-crowned sparrows tutored with individual phrases. AB - Behavioral ontogeny involves the interaction of innate predispositions and experience. In bird song learning, one approach to exploring this interaction is to examine the songs rehearsed by young birds whose exposure to tutor models has been carefully controlled. Here, I analyzed the rehearsed repertoire in Nuttall's white-crowned sparrows (Zonotrichia leucophrys nuttalli) tutored with individual phrases of conspecific and heterospecific songs. The proportions of phrase types rehearsed indicate that the learning biases evident in crystallized song are manifest early on, suggesting preferential memorization rather than preferential retention during attrition. The proportion of songs beginning with whistles increased during song rehearsal and phrase sequence variability decreased, consistent with the idea that innate syntax specifications guide song rehearsal. Single-phrase tutored birds overproduced phrases to the same extent previously observed in birds tutored with full, normal song but retained fewer phrase types in their crystallized repertoires. This suggests that in this subspecies, acquired syntax information does not affect the number of phrase types memorized and rehearsed but does affect repertoire attrition at the end of the sensorimotor phase. I discuss these results with a focus on the action of innate templates in song development and subspecies differences in this process. PMID- 29462651 TI - No subchronic toxicity of multiple herbicide-resistant soybean FG72 in Sprague Dawley rats by 90-days feeding study. AB - The genetically modified (GM) soybean FG72 contains two exogenous genes: p hydroxyphenylpyruvate dioxygenase (hppd) and double mutant 5-enol pyruvylshikimate-3-phosphate synthase (2mepsps), endowing the FG72 with the glyphosate and isoxaflutole herbicides resistant abilities for presence of the 2mEPSPS and HPPD W336 proteins. A food safety assessment of GM soybean FG72 was evaluated by a 90-days feeding study using three different dietary concentrations (7.5%, 15%, or 30% w/w) of the GM soybean or its corresponding non-GM cultivar Jack fed to Sprague-Dawley rats. In our study, no biologically significant differences on animal daily clinical signs, body weights, clinical observations, hematology, clinical chemistry, histopathology on selected organs were observed within the GM soybean groups and among the GM soybean groups, the non-GM soybean groups and the control group. The results of the 90-days subchronic feeding study demonstrated that the GM soybean FG72 is as safe as the conventional non-GM soybean Jack. PMID- 29462652 TI - The role of intraamygdaloid neurotensin and dopamine interaction in conditioned place preference. AB - Tridecapeptide Neurotensin (NT) is widely distributed in the central nervous system where it acts as a neurotransmitter and neuromodulator. The central nucleus of amygdala (CeA), part of the limbic system, plays an important role in learning, memory, anxiety and reinforcing mechanisms. Our previous data showed that NT microinjected into the CeA has positive reinforcing properties. We supposed that these effects might be due to modulations of the mesolimbic dopamine system. The aim of our study was to examine in the CeA the possible effects of NT and dopamine interaction on reinforcement by conditioned place preference test. Male Wistar rats were microinjected bilaterally with 100 ng NT or 2 MUg D1 dopamine receptor antagonist alone, or D1 dopamine antagonist 15 min before 100 ng NT treatment or vehicle solution into the CeA. Other animals received 4 MUg D2 dopamine receptor antagonist Sulpiride alone, or administration of D2 dopamine receptor antagonist 15 min before 100 ng NT treatment or vehicle solution into the CeA. Rats that received 100 ng NT spent significantly more time in the treatment quadrant during the test session. Pre-treatment with the D1 dopamine antagonist, blocked the effects of NT. D2 dopamine receptor antagonist pretreatment could prevent the positive reinforcing effects of NT as well. Antagonists themselves did not influence the place preference. Our results show that the rewarding effect of NT can be due to the modulation of DA system, since its effects could be blocked by either D1 dopamine or D2 dopamine antagonist preteatment. PMID- 29462654 TI - Neighbourhoods and obesity: A prospective study of characteristics of the built environment and their association with adiposity outcomes in children in Montreal, Canada. AB - This paper examined prospective associations between built environment features assessed at baseline using direct audits and adiposity outcomes two years later in Montreal, Canada. Data stem from the Quebec Adipose and Lifestyle Investigation in Youth study of 630 children aged 8-10 years with a parental history of obesity. Baseline measurements took place between 2005 and 2008. Follow-up took place between 2008 and 2011. Built environment features were assessed at baseline in up to 10 contiguous street segments around participants' residential addresses using on-site audits. Analyses were restricted to participants who reported the same address both at baseline and follow-up. Prospective associations between adiposity outcomes at follow-up (BMI z-score and waist-height ratio) and built environment features at baseline (traffic-calming features, pedestrian aids, disorder, physical activity facilities, convenience stores, and fast-food restaurants) were examined using multivariable regression models. 391 children were included in the analyses. In fully-adjusted models, children living in residential areas with presence of pedestrian aids had lower BMI z-score, and lower waist-height ratio. Also, children residing in residential areas with at least one convenience store had lower BMI z-score, and lower waist height ratio at follow-up. Findings provide evidence of the potential role of street-level urban design features in shaping childhood adiposity. To better inform policy and intervention, future research should explore the possibility of reducing obesogenic neighbourhoods by enhancing street-level design features. PMID- 29462655 TI - Convergence of BOLD and ERP measures of neural reactivity to emotional faces in children and adolescents with and without anxiety disorders. AB - The neural bases of emotion are commonly measured using blood-oxygen-level dependent (BOLD) signal and the late positive potential (LPP) event-related potential (ERP) component, but rarely together in the same individuals. Despite evidence of developmental changes in processing socio-emotional signals (e.g., faces) as reflected by both BOLD and LPP indices of brain maturation, the literature on the correspondence between these measures is limited to healthy adults, leaving questions regarding such correspondence across development and in clinical populations unaddressed. We examined the relationship between BOLD and LPP during an emotional face processing task in a large sample of youth (N = 70; age 7-19 years) with and without anxiety disorders, and tested whether BOLD signal in regions corresponding to LPP may account for age-related decreases in LPP. Greater activation in bilateral inferior frontal gyrus (IFG)/orbitofrontal gyrus (OFG), left supplementary motor area, right superior parietal lobule, and bilateral amygdala correlated with enhanced LPP to emotional faces in both anxious and healthy youth. Older youth exhibited reduced activation in bilateral IFG/OFG and bilateral amygdala, as well as reduced LPP. Decreased right IFG/OFG activation mediated the association between age and LPP. These findings support correspondence between these measures and need for multi-method approaches and indicate that age-related decreases in LPP may be driven, in part, by decreased IFG/OFG activation. PMID- 29462656 TI - EEG phase states at stimulus onset in a variable-ISI Go/NoGo task: Effects on ERP components. AB - Previous EEG-ERP dynamics studies found non-random "preferred" EEG phases at stimulus onset in a fixed interstimulus interval (ISI) equiprobable auditory Go/NoGo paradigm, with substantial effects on ERP components. Here we changed to a variable ISI task to prevent/reduce preferential phase occurrence. Discrete Fourier transforms decomposed prestimulus EEG at Cz for each trial to calculate the phase of different frequencies at stimulus onset; we combined these into the delta, theta, alpha, and beta bands, and then sorted trials into phase quartiles for each. ERPs from the raw EEG, assessed using temporal Principal Components Analyses, were examined as a function of phase at stimulus onset. Preferential phase occurrence was reduced as predicted, but random phase substantially impacted component amplitudes. For example, negativity in delta enhanced Go and NoGo P3b; and in theta reduced NoGo but not Go P3b. Overall, EEG phases at stimulus onset support differential cognitive processing in this two-choice task. PMID- 29462653 TI - Neuroinflammation in Alzheimer's disease: Pleiotropic roles for cytokines and neuronal pentraxins. AB - Neuroinflammation is a potential factor speculated to underlie Alzheimer's disease (AD) etiopathogenesis and progression. The overwhelming focus in this area of research to date has been on the chronic upregulation of pro-inflammatory cytokines to understand how neuroinflammatory mechanisms contribute to neurodegeneration. Yet, it is important to understand the pleiotropic roles of these cytokines in modulating neuroinflammation in which they cannot be labeled as a strictly "good" or "bad" biomarker phenotype. As such, biomarkers with more precise functions are needed to better understand how neuroinflammation impacts the brain in AD. Neuronal pentraxins are a concentration- dependent group of pro- or anti- inflammatory cytokines. There is contradictory evidence of these pentraxins as being both neuroprotective and potentially detrimental in AD. Potential neuroprotective examples include their ability to predict AD-related outcomes such as cognition, memory function and synaptic refinement. This review will briefly outline the basis of AD and subsequently summarize findings for neuropathological mechanisms of neuroinflammation, roles for traditional pro-and anti-inflammatory cytokines, and data found thus far on the neuronal pentraxins. PMID- 29462657 TI - Serlopitant for the treatment of chronic pruritus: Results of a randomized, multicenter, placebo-controlled phase 2 clinical trial. AB - BACKGROUND: The substance P/neurokinin 1 receptor pathway is critical in chronic pruritus; anecdotal evidence suggests that antagonism of this pathway can reduce chronic itch. OBJECTIVE: To assess the safety and efficacy of the substance P/neurokinin 1 receptor antagonist serlopitant in treating chronic pruritus. METHODS: Eligible patients with severe chronic pruritus who were refractory to antihistamines or topical steroids were randomized to serlopitant, 0.25, 1, or 5 mg, or to placebo, administered once daily for 6 weeks as monotherapy or with midpotency steroids and emollients. The primary efficacy end point was percentage change in visual analog scale pruritus score from baseline. RESULTS: Serlopitant treatment resulted in a dose-dependent decrease in pruritus. The mean percentage decreases from baseline visual analog scale pruritus scores were statistically significantly larger with the 1- and 5-mg doses of serlopitant (P = .022 and P = .013, respectively) than with placebo at week 6. No significant safety or tolerability differences were detected among the groups. LIMITATIONS: The sample size was insufficient for subgroup analyses of the efficacy of serlopitant for chronic pruritus on the basis of underlying conditions. CONCLUSIONS: Serlopitant, 1 mg and 5 mg daily, was associated with a statistically significant reduction in chronic pruritus and was well tolerated (NCT01951274).

PMID- 29462659 TI - Safer approaches to therapeutic modulation of TGF-beta signaling for respiratory disease. AB - The transforming growth factor (TGF)-beta cytokines play a central role in development and progression of chronic respiratory diseases. TGF-beta overexpression in chronic inflammation, remodeling, fibrotic process and susceptibility to viral infection is established in the most prevalent chronic respiratory diseases including asthma, COPD, lung cancer and idiopathic pulmonary fibrosis. Despite the overwhelming burden of respiratory diseases in the world, new pharmacological therapies have been limited in impact. Although TGF-beta inhibition as a therapeutic strategy carries great expectations, the constraints in avoiding compromising the beneficial pleiotropic effects of TGF-beta, including the anti-proliferative and immune suppressive effects, have limited the development of effective pharmacological modulators. In this review, we focus on the pathways subserving deleterious and beneficial TGF-beta effects to identify strategies for selective modulation of more distal signaling pathways that may result in agents with improved safety/efficacy profiles. Adverse effects of TGF beta inhibitors in respiratory clinical trials are comprehensively reviewed, including those of the marketed TGF-beta modulators, pirfenidone and nintedanib. Precise modulation of TGF-beta signaling may result in new safer therapies for chronic respiratory diseases. PMID- 29462660 TI - Evaluation of the medical devices benchmark materials in the controlled human patch testing and in the RhE in vitro skin irritation protocol. AB - Several irritants were used in the in vitro irritation medical device round robin. The objective of this study was to verify their irritation potential using the human patch test (HPT), an in vitro assay, and in vivo data. The irritants were lactic acid (LA), heptanoic acid (HA), sodium dodecyl sulfate (SDS), Genapol(r) X-80 (GP), and Y-4 polymer. Dilute saline and sesame seed oil (SSO) solutions of each were evaluated using a 4 and 18 h HPT and the EpiDermTM SIT-MD RhE assay; results were then compared to existing rabbit skin irritation test data. Results from the 4 h HPT were negative in most cases except for GP and SDS, while the 18 h HPT also identified some LA, HA, and GP samples as irritants. EpiDermTM SIT-MD correctly identified all irritants except GP in SSO due to limited solubility. Data from cutaneous rabbit irritation tests were negative, while all intracutaneous results were strongly or weakly positive except for the most dilute GP solutions. These findings indicate that EpiDermTM SIT-MD results correlate with those from the rabbit intracutaneous test and confirm that RhE assays are suitable replacements for animals in evaluating the tissue irritation potential of medical devices. PMID- 29462662 TI - A balanced ATP driving force module for enhancing photosynthetic biosynthesis of 3-hydroxybutyrate from CO2. AB - Using engineered photoautotrophic microorganisms for the direct chemical synthesis from CO2 is an attractive direction for both sustainability and CO2 mitigation. However, the behaviors of non-native metabolic pathways may be difficult to control due to the different intracellular contexts between natural and heterologous hosts. While most metabolic engineering efforts focus on strengthening driving forces in pathway design to favor biochemical production in these organisms, excessive driving force may be detrimental to product biosynthesis due to imbalanced cellular intermediate distribution. In this study, an ATP-hydrolysis based driving force module was engineered into cyanobacterium Synechococcus elongatus PCC 7942 to produce 3-hydroxybutyrate (3HB), a valuable chemical feedstock for the synthesis of biodegradable plastics and antibiotics. However, while the ATP driving force module is effective for increasing product formation, uncontrolled accumulation of intermediate metabolites likely led to metabolic imbalance and thus to cell growth inhibition. Therefore, the ATP driving force module was reengineered by providing a reversible outlet for excessive carbon flux. Upon expression of this balanced ATP driving force module with 3HB biosynthesis, engineered strain produced 3HB with a cumulative titer of 1.2 g/L, a significant increase over the initial strain. This result highlighted the importance of pathway reversibility as an effective design strategy for balancing driving force and intermediate accumulation, thereby achieving a self regulated control for increased net flux towards product biosynthesis. PMID- 29462661 TI - p66Shc regulates migration of castration-resistant prostate cancer cells. AB - Metastatic castration-resistant (CR) prostate cancer (PCa) is a lethal disease for which no effective treatment is currently available. p66Shc is an oxidase previously shown to promote androgen-independent cell growth through generation of reactive oxygen species (ROS) and is elevated in clinical PCa and multiple CR PCa cell lines. We hypothesize p66Shc also increases the migratory activity of PCa cells through ROS and investigate the associated mechanism. Using the transwell assay, our study reveals that the level of p66Shc protein correlates with cell migratory ability across several PCa cell lines. Furthermore, we show hydrogen peroxide treatment induces migration of PCa cells that express low levels of p66Shc in a dose-dependent manner, while antioxidants inhibit migration. Conversely, PCa cells that express high levels of endogenous p66Shc or by cDNA transfection possess increased cell migration which is mitigated upon p66Shc shRNA transfection or expression of oxidase-deficient dominant-negative p66Shc W134F mutant. Protein microarray and immunoblot analyses reveal multiple proteins, including ErbB-2, AKT, mTOR, ERK, FOXM1, PYK2 and Rac1, are activated in p66Shc-elevated cells. Their involvement in PCa migration was examined using respective small-molecule inhibitors. The role of Rac1 was further validated using cDNA transfection and, significantly, p66Shc is found to promote lamellipodia formation through Rac1 activation. In summary, the results of our current studies clearly indicate p66Shc also regulates PCa cell migration through ROS-mediated activation of migration-associated proteins, notably Rac1.

AB - Zinc phthalocyanine (ZnPc) is a highly potent second-generation photosensitizer for cancer photodynamic therapy (PDT) with attractive photo-physical and photo chemical properties. However, poor solubility and strong trend of crystallization prevent it from loading in most of drug delivery systems and hamper its further application. Herein, to overcome this problem, an amphiphilic block copolymer poly(ethylene glycol)-poly[2-(methylacryloyl)ethylnicotinate] (PEG-PMAN) with aromatic nicotinate is used to load ZnPc for their pi-pi interactions. The formed PEG-PMAN/ZnPc nanoparticle (PPZ) dramatically increases reactive oxygen species production in osteosarcoma cells after light irradiation, causes mitochondrial injury and promotes cell cycle arrest at G2/M, leading to a 100-fold cytotoxicity improvement comparing with free ZnPc. The excellent therapeutic effectiveness and safety of PPZ are also proved by in vivo experiments operating on osteosarcoma model. The finding above indicates that PPZ has promising clinical applications as a next-generation photosensitizer in PDT of osteosarcoma.

AB - : Individual variations studies are important to understand the snakebite envenoming and to improve the antivenom production and its effectiveness. In this way, the objective of this study was a comparative analysis of intraspecific variation in the venom composition of 22 Crotalus durissus collilineatus specimens through proteomic techniques. Venoms were fractionated by RP-FPLC, and analyzed by SDS-PAGE and mass spectrometry. Although similar, chromatographic and electrophoretic profiles showed significant qualitative and quantitative differences. Some venom components were identified for the very first time in C. d. collilineatus, such as glutathione peroxidase, nerve growth factor, 5' nucleotidase, angiotensin-converting enzyme, carboxypeptidase, phosphodiesterase, glutaminyl cyclase and phospholipase B. Regarding hyaluronidase activity, 2 venoms did not present detectable enzyme activity in the tested amounts. Additionally, in vivo crotalic envenoming in mice showed that venoms from different specimens resulted in diversified changes of biochemical and immunological parameters, such as creatine kinase and interleukin 6. This study demonstrated significant intraspecific variations in the venom of C. d. collilineatus, which may impact the production and effectiveness of the antivenom therapy. BIOLOGICAL SIGNIFICANCE: This study performed the proteomic and functional analyzes of 22 C. d. collilineatus individual venoms and verified the occurrence of quali and quantitative variations among them. The venoms evaluated caused envenomings with different changes in biochemical and immunological parameters. These results confirm the need to use a pool of venoms with the greatest possible variability in the preparation of antivenoms, in order to improve their effectiveness. In addition, this study was able to identify for the first time 8 different proteins in this subspecies venom, increasing knowledge about its composition and showing that it is a source of these proteins with possible biotechnological applications.

AB - BACKGROUND: Cognitive impairment (CI) is frequent in patients with multiple sclerosis (PwMS) and could negatively affect family social and vocational activities. Detecting CI is clinically relevant, so the emerging question is the strategy for assessing cognition in MS. OBJECTIVE: An update on cognitive assessment in PwMS with use of standard neuropsychological (NP) tests and ecological tools. RESULTS: The minimal cognitive assessment in MS should include at least NP tests assessing information processing speed (IPS) and verbal and visuospatial episodic memory. The IPS could be easily and quickly evaluated with symbol digit substitution tests by using paper for the oral version of the Symbol Digit Modalities Test or a laptop for the Computerised Speed Cognitive Test. The comprehensive NP battery must be performed by a qualified neuropsychologist to adequately characterize the extent and severity of CI in PwMS. The quiet and controlled environment used for this standardized assessment could be a limitation for generalizing the results because it does not reflect real daily life conditions. Thus, this context could decrease the ability to detect some cognitive deficits that could occur only in more complex situations. Thus, ecological evaluation seems a complementary and promising approach for detecting cognitive abnormalities in daily activities. CONCLUSION: Recent efforts have been made to detect and characterize cognitive deficits in PwMS. Some IPS and episodic memory NP tests have been validated in MS and should be proposed to patients in the clinical setting. Besides NP tests, ecological tools are becoming important for detecting cognitive dysfunction in everyday-like conditions. Further research is needed to validate relevant tools for monitoring cognition in MS and the ability to detect clinically meaningful change in longitudinal studies.

AB - Spinocerebellar ataxia (SCA) types 1, 2, 3, 6, and 7, associated with a (CAG)n repeat expansion in coding sequences, are the most prevalent autosomal dominant ataxias worldwide (approximately 60% of the cases). In addition, the phenotype of SCA2 expansions has been now extended to Parkinson disease and amyotrophic lateral sclerosis. Their diagnosis is currently based on a PCR to identify small expanded alleles, followed by a second-level test whenever a false normal homozygous or a CAT interruption in SCA1 needs to be verified. Next-generation sequencing still does not allow efficient detection of these repeats. Here, we show the efficacy of a novel, rapid, and cost-effective method to identify and size pathogenic expansions in SCA1, 2, 3, 6, and 7 and recognize large alleles or interruptions without a second-level test. Twenty-five healthy controls and 33 expansion carriers were analyzed: alleles migrated consistently in different PCRs and capillary runs, and homozygous individuals were always distinguishable from heterozygous carriers of both common and large (>100 repeats) pathogenic CAG expansions. Repeat number could be calculated counting the number of peaks, except for the largest SCA2 and SCA7 alleles. Interruptions in SCA1 were always visible. Overall, our method allows a simpler, cost-effective, and sensibly faster SCA diagnostic protocol compared with the standard technique and to the still unadapted next-generation sequencing. PMID- 29462667 TI - A Proximity Extension Assay (PEA)-based method for quantification of bevacizumab. AB - INTRODUCTION: Proximity Extension Assay (PEA) is a direct one-step protein quantification method using a pair of DNA oligonucleotides linked to antibodies against the target molecule. It requires polyclonal or two monoclonal antibodies (mAbs) that bind to target epitopes close enough to form a DNA duplex which is quantified by real-time PCR. Bevacizumab, an anti-cancer drug, is a mAb against vascular endothelial growth factor with common cardiovascular adverse effects. It is widely used off-label to treat neovascular eye disorders by intravitreal application of small doses. Even then, certain amount reaches systemic circulation which is considered relevant regarding safety. We aimed to set-up a PEA-based assay for bevacizumab in human plasma and to preliminary evaluate it in patients treated intravitreally. METHODS: We tested (PEA, quantitative PCR) several combinations of commercial mAbs and a Fab fragment against bevacizumab. The best combination was used to quantify bevacizumab in three patients donating plasma before and 24 h after the first intravitreal injection. RESULTS: A combination of a mAb and a Fab fragment (HCA184 and HCA182, Bio-Rad Laboratories, Inc.) performed best: standard curve R2 0.98, linear dynamic range 1-1000 pM, lower limit of quantification 1 pM (149 pg/mL) and a satisfactory precision (coefficient of variation 12%). All pre-dose patient concentrations were zero, while post-dose concentrations were 10.94, 13.73 and 55.49 ng/mL, in line with previous reports. DISCUSSION: This is the first set-up of a PEA-based assay for quantification of bevacizumab in human plasma. Its good performance and high sensitivity support further evaluation for potential uses particularly when the expected concentrations are low.

AB - The fully specified name of a concept in SNOMED CT is formed by a term to which in the typical case is added a semantic tag. The latter is meant to disambiguate homonymous terms and to indicate in which major subhierarchy of SNOMED CT that concept fits. We have developed a method to determine whether a concept's tag correctly identifies its place in the hierarchy, and applied this method to an analysis of all active concepts in every SNOMED CT release from January 2003 to January 2017. Our results show (1) that there are concepts in almost every release whose semantic tag does not match their placement in the hierarchy, (2) that it is primarily disorder concepts that are involved, and (3) that the number of such mismatches increase since the July 2012 version. Our analysis determined that it is primarily the absence of a mechanism in the SNOMED CT authoring environment to suggest stated relationships for very similar concepts that is responsible for the mismatches. We argue that the SNOMED CT authoring environment should treat the semantic tags as part of the formal structure so that methods can be implemented to keep the sub-hierarchies in sync with the semantic tags. PMID- 29462669 TI - Assessing the practice of biomedical ontology evaluation: Gaps and opportunities. AB - With the proliferation of heterogeneous health care data in the last three decades, biomedical ontologies and controlled biomedical terminologies play a more and more important role in knowledge representation and management, data integration, natural language processing, as well as decision support for health information systems and biomedical research. Biomedical ontologies and controlled terminologies are intended to assure interoperability. Nevertheless, the quality of biomedical ontologies has hindered their applicability and subsequent adoption in real-world applications. Ontology evaluation is an integral part of ontology development and maintenance. In the biomedicine domain, ontology evaluation is often conducted by third parties as a quality assurance (or auditing) effort that focuses on identifying modeling errors and inconsistencies. In this work, we first organized four categorical schemes of ontology evaluation methods in the existing literature to create an integrated taxonomy. Further, to understand the ontology evaluation practice in the biomedicine domain, we reviewed a sample of 200 ontologies from the National Center for Biomedical Ontology (NCBO) BioPortal the largest repository for biomedical ontologies-and observed that only 15 of these ontologies have documented evaluation in their corresponding inception papers. We then surveyed the recent quality assurance approaches for biomedical ontologies and their use. We also mapped these quality assurance approaches to the ontology evaluation criteria. It is our anticipation that ontology evaluation and quality assurance approaches will be more widely adopted in the development life cycle of biomedical ontologies.

AB - The adhesion G protein-coupled receptor A2 (Adgra2) is a seven transmembrane receptor that has been described to be a regulator for angiogenesis in mice. Furthermore, the zebrafish ouchless mutant is unable to develop dorsal root ganglia through a disrupted trafficking of Adgra2. Besides RNA sequencing data, nothing is reported about Adgra2 in the south African crawled frog Xenopus laevis. In this study, we investigated for the first time the spatio-temporal expression of adgra2 during early Xenopus embryogenesis in detail. In silico approaches showed that the genomic adgra2 region as well as the Adgra2 protein sequence is highly conserved among different species including Xenopus. RT-PCR experiments confirmed that embryonic adgra2 expression is primarily detected at the beginning of neurulation and is then present throughout the whole Xenopus embryogenesis until stage 42. Whole mount in situ hybridization approaches visualized adgra2 expression in many tissues during Xenopus embryogenesis such as the cardiovascular system including the heart, the migrating neural crest cells and the developing eye including the periocular mesenchyme. Our results indicate a role of Adgra2 for embryogenesis and are a good starting point for further functional studies during early vertebrate development. PMID- 29462672 TI - Use of high-dose intermittent systemic glucocorticoids and the risk of fracture in patients with chronic obstructive pulmonary disease. AB - INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is characterised by persistent airflow obstruction and respiratory symptoms. While short course systemic GCs are prescribed in patients with acute COPD exacerbations, little is known of the risk of fractures with intermittent exposure to high-dose GC and the effect of proxies of disease severity. METHODS: A case-control study was conducted using the Danish National Hospital Discharge Registry (NHDR) between January 1996 to December 2011. Conditional logistics regression models were used to derive adjusted odds ratios (OR) risk of fractures in subjects with COPD stratified by intermittent high-dose, and proxies of disease severity. RESULT: A total of 635,536 cases and the same number of controls were identified (mean age 67.5+/-13.8, 65% female). COPD patients with intermittent use of high average daily dose oral glucocorticoids did not have an increased risk of any, osteoporotic, hip or clinically symptomatic vertebral fracture compared to non COPD patients (adj. OR 0.65; 95% CI: 0.50-0.86, 0.70; 95% CI: 0.70-0.99, 1.17; 95% CI: 0.59-2.32, 1.98; 95% CI: 0.59-6.65 respectively). We identified an elevated risk of osteoporotic fracture among patients who visited the emergency unit (adj. OR 1.47; 95% CI 1.20-1.79) or were hospitalised in the past year for COPD (adj. OR 1.76; 95% CI 1.66-1.85). Current GC use among COPD patients was associated with an increased risk of osteoporotic, hip and clinically symptomatic vertebral fractures compared to patients without COPD. CONCLUSION: Intermittent high-dose GCs was not associated with an increased risk of any, osteoporotic, hip or clinically symptomatic vertebral fractures in patients with COPD. Current GC use was however associated with an increased risk of hip and clinically symptomatic vertebral fractures. Therefore, emphasis on prophylactic treatment of fractures may not be essential in patients with COPD receiving intermittent dose of GCs, whereas this should be considered for high-dose long-term users with advanced COPD disease stage, postmenopausal women and men over 40years. PMID- 29462670 TI - Microvesicles as Emerging Biomarkers and Therapeutic Targets in Cardiometabolic Diseases. AB - Microvesicles (MVs, also known as microparticles) are small vesicles that originate from plasma membrane of almost all eukaryotic cells during apoptosis or activation. MVs can serve as extracellular vehicles to transport bioactive molecules from their parental cells to recipient target cells, thereby serving as novel mediators for intercellular communication. Importantly, more and more evidence indicates that MVs could play important roles in early pathogenesis and subsequent progression of cardiovascular and metabolic diseases. Elevated plasma concentrations of MVs, originating from red blood cells, leukocytes, platelets, or other organs and tissues, have been reported in various cardiometabolic diseases. Circulating MVs could serve as potential biomarkers for disease diagnosis or therapeutic monitoring. In this review, we summarized recently published studies in the field and discussed the role of MVs in the pathogenesis of cardiometabolic diseases. The emerging values of MVs that serve as biomarker for non-invasive diagnosis and prognosis, as well as their roles as novel therapeutic targets in cardiometabolic diseases, were also described. PMID- 29462673 TI - Heterotopic ossification and lessons learned from fifteen years at war: A review of therapy, novel research, and future directions for military and civilian orthopaedic trauma. AB - Heterotopic ossification, the formation of bone in soft tissues, is a common complication of the high-energy extremity trauma sustained in modern armed conflict. In the past 15years, military treatment facilities and aligned laboratories have been in a unique position to study and treat this process due to the high volume of patients with these injuries secondary to blast trauma. The devastating nature of these wounds has limited traditional therapeutic options, necessitating alternative solutions to prophylaxis and initial treatment producing substantial advances in modeling, prophylaxis, detection, and therapy. Specific developments include establishment of an animal model that reproduces the systemic and local tissue injury of blast injuries, the use of molecular assays and predictive modeling in clinical decision making, advances in early detection including Raman spectroscopy, and investigation of prophylactic and therapeutic pharmacotherapy targeting the molecular pathways of aberrant bone formation. In this review article, we will present the literature to date, ongoing studies, and future directions for investigation of heterotopic ossification, with a focus on military-specific research. PMID- 29462674 TI - Lysophosphatidic acid in medicinal herbs enhances prostaglandin E2 and protects against indomethacin-induced gastric cell damage in vivo and in vitro. AB - Lysophosphatidic acid (LPA) is a bioactive phospholipid that induces diverse biological responses. Recently, we found that LPA ameliorates NSAIDs-induced gastric ulcer in mice. Here, we quantified LPA in 21 medicinal herbs used for treatment of gastrointestinal (GI) disorders. We found that half of them contained LPA at relatively high levels (40-240 MUg/g) compared to soybean seed powder (4.6 MUg/g), which we previously identified as an LPA-rich food. The LPA in peony (Paeonia lactiflora) root powder is highly concentrated in the lipid fraction that ameliorates indomethacin-induced gastric ulcer in mice. Synthetic 18:1 LPA, peony root LPA and peony root lipid enhanced prostaglandin E2 production in a gastric cancer cell line, MKN74 cells that express LPA2 abundantly. These materials also prevented indomethacin-induced cell death and stimulated the proliferation of MKN74 cells. We found that LPA was present in stomach fluids at 2.4 MUM, which is an effective LPA concentration for inducing a cellular response in vitro. These results indicated that LPA is one of the active components of medicinal herbs for the treatment of GI disorder and that orally administered LPA-rich herbs may augment the protective actions of endogenous LPA on gastric mucosa. PMID- 29462675 TI - Spiroides shrubs on Qinghai-Tibetan Plateau: Multilocus phylogeography and palaeodistributional reconstruction of Spiraea alpina and S. Mongolica (Rosaceae). AB - A common hypothesis for the rich biodiversity found in mountains is uplift-driven diversification. Using a multilocus approach, here we assessed the influence of Qinghai-Tibetan Plateau (QTP) uplift and fluctuating regional climate on genetic diversity of two sister spiroides shrubs, Spiraea alpina and S. mongolica. Combined with palaeodistributional reconstruction modelling, we investigated the current and past-predicted distribution of these species under different climatic episodes. The study demonstrated that continuous pulses of retreat and expansion during last glacial-interglacial episodes, combined with the uplifting of QTP shaped the current distribution of these species. All the populations showed high level of genetic diversity based on both cpDNA and SSR markers. The average gene diversity within populations based on cpDNA markers was 0.383 +/- 0.052 for S. alpina and 0.477 +/- 0.048 for S. mongolica. The observed and expected heterozygosities based on SSR for both Spiraea alpina and S. mongolicawere HE(0.72-0.90)/HO(0.35-0.78) and HE(0.77-0.92)/HO(0.47-0.77) respectively. Palaeodistributional reconstruction indicated species' preferences at southeastern edge of the plateau during last glacial maximum, at higher altitude areas of QTP and range expansion to central plateau during the interglacial episodes. Assignment tests in STRUCTURE, discriminant analysis of principal coordinates and Immigrants analysis in GENECLASS based on nuclear SSR markers did not support the hypothesis of gene flow between both the species. However, maximum likelihood approach based on cpDNA showed sharing of haplotypes between both species.

PMID- 29462677 TI - Characterization of the complete mitochondrial genome of Biston marginata (Lepidoptera: Geometridae) and phylogenetic analysis among lepidopteran insects. AB - The complete mitochondrial genome (mitogenome) of Biston marginata (Lepidoptera: Geometridae) was determined and annotated. The circular genome is 15,470bp long and it contains the entire set of 37 genes usually present in lepidopteran mitogenomes. The nucleotide composition of the genome is highly A+T biased, accounting for 81.20%, with a slightly positive AT skewness (0.028), indicating the occurrence of more As than Ts, as found in other Geometridae species. Except for cox1 gene starts with non-canonical initial codon CGA, all protein-coding genes start with ATN codon. Three of the 13 PCGs (protein coding gene) had an incomplete termination codon, T or TA, while the others terminated with TAA. All tRNA genes are predicted to fold into typical clover-leaf secondary structure, except for the trnS1 (AGN), in which the dihydrouridine (DHU) arm could not form a stable stem-loop structure. The A+T-rich region of 343bp is comprised of non repetitive sequences, but have several distinctive features, including the motif "ATAGA" followed by a 19bp poly-T stretch, a microsatellite-like (TA)7 element next to the ATTTA motif. The phylogenetic analyses support the view that the B. marginata is closely related to the Biston pantrinaria, and confirm that Biston marginata belongs to the family Geometridae. PMID- 29462678 TI - The effect of different substitute groups and molecular weights of fucoidan on neuroprotective and anticomplement activity. AB - Ten fucoidan (FPS) derivatives were successfully synthesized, and their potential neuroprotective and anticomplement activities were investigated employing various established in vitro systems. The aim of the present study was to investigate the effects of different substitute groups and molecular weights of fucoidan on neuroprotective and anticomplement activities. All FPS derivatives possessed considerable neuroprotective and anticomplement activities and had stronger activities than FPS in certain tests. The in vitro results found that sulfated and benzoylated derivatives could reverse the decreased mitochondrial activity and decreased lactate dehydrogenase (LDH) and reactive oxygen species (ROS) release induced by 6-hydroxydopamine (6-OHDA, P<0.01 or P<0.001), which provides further evidence that sulfate and benzoylate groups could enhance the neuroprotective activity of fucoidan. In anticomplement experiments, all samples showed anticomplement activity in both systems; however, the sulfated and benzoylated derivatives showed better activity than fucoidan, with higher molecular weights showing the strongest activity. Available data suggested that substituted groups of fucoidan played an important role on neuroprotective and anticomplement activities. The mechanism of the influence of the neuroprotective and anticomplement activities of samples of the substituted groups was indicated. PMID- 29462679 TI - Novel pH sensitive dual drug loaded-gelatin methacrylate/methacrylic acid hydrogel for the controlled release of antibiotics. AB - The aim of the present study was to develop a novel pH sensitive gelatin methacrylate hydrogel for the controlled delivery of Gentamicin (GS) and Ampicillin (Amp). GS and Amp having synergistic activity is effective in killing multi drug resistant bacteria. The hydrogel was well characterized using FTIR, XRD and SEM techniques. The drug loading and encapsulation efficiency were found to be 85.0 and 77.0% for GS, 79.0 and 88.0% for Amp, respectively. The in vitro swelling, degradation and release profiles suggest the pH dependent behaviour of hydrogel. DPPH Assay confirmed the role of 2-amino guanidine in nullifying the side effect of GS and inhibition percentage of DDLHG is found to be 85.0%. Antimicrobial studies revealed the increased efficiency of the drug combination in killing bacteria. PMID- 29462680 TI - Thermal unfolding of human lysozyme induces aggregation: Recognition of the aggregates by antisera against the native protein. AB - Protein aggregates are formed due to the inappropriate folding of polypeptides. Human lysozyme (HLZ) plays an important role in the innate immune response of the body and has been used extensively as a model protein to study aggregation. In this study, we showed that HLZ undergoes unfolding induced aggregation when heated by using spectroscopic and microscopic techniques. We further showed that the aggregates were recognized by polyclonal antibodies against the native HLZ. The consequences of these observations are further co-related with mammalian physiology. PMID- 29462681 TI - Expression of vascular endothelial growth factor in cardiac repair: Signaling mechanisms mediating vascular protective effects. AB - The present study was aimed to investigate the vascular endothelial growth factor expression pattern in acute myocardial infarction induced rats. Serum level of vascular endothelial growth factor and its mRNA expression in myocardium were determined. Protein expression of vascular endothelial growth factor and endothelial nitric oxide synthase were measured. Serum level of vascular endothelial growth factor was increased 105.3, 260, 378.2 and 271.3% following the onset of acute myocardial infarction at 3, 6, 9 and 12days respectively. The mRNA and protein expression of vascular endothelial growth factor was substantially increased following the onset of acute myocardial infarction. Protein expression of endothelial nitric oxide synthase was increased up to 1.02 fold. Taking all these data together, it is concluded that the vascular endothelial growth factor was increased in serum and tissue and attained peak at 9th day following the onset of acute myocardial infarction. Increased vascular endothelial growth factor level in serum and tissue could increase endothelial cell proliferation and angiogenesis, and endothelial nitric oxide synthase could inhibit apoptosis and protect cardiomyocytes. In conclusion, the increased vascular endothelial growth factor expression could play an essential role in cardiac repair following the onset of acute myocardial infarction. PMID- 29462682 TI - Modulation of Kv3.1b potassium channel level and intracellular potassium concentration in 158N murine oligodendrocytes and BV-2 murine microglial cells treated with 7-ketocholesterol, 24S-hydroxycholesterol or tetracosanoic acid (C24:0). AB - Little is known about K+ regulation playing major roles in the propagation of nerve impulses, as well as in apoptosis and inflammasome activation involved in neurodegeneration. As increased levels of 7-ketocholesterol (7KC), 24S hydroxycholesterol (24S-OHC) and tetracosanoic acid (C24:0) have been observed in patients with neurodegenerative diseases, we studied the effect of 24 and/or 48 h of treatment with 7KC, 24S-OHC and C24:0 on Kv3.1b potassium channel level, intracellular K+ concentration, oxidative stress, mitochondrial dysfunction, and plasma membrane permeability in 158N oligodendrocytes and BV-2 microglial cells. In 158N cells, whereas increased level of Kv3.1b was only observed with 7KC and 24S-OHC but not with C24:0 at 24 h, an intracellular accumulation of K+ was always detected. In BV-2 cells treated with 7KC, 24S-OHC and C24:0, Kv3.1b level was only increased at 48 h; intracellular K+ accumulation was found at 24 h with 7KC, 24S-OHC and C24:0, and only with C24:0 at 48 h. Positive correlations between Kv3.1b level and intracellular K+ concentration were observed in 158N cells in the presence of 7KC and 24S-OHC, and in 7KC-treated BV-2 cells at 48 h. Positive correlations were also found between Kv3.1b or the intracellular K+ concentration, overproduction of reactive oxygen species, loss of transmembrane mitochondrial potential and increased plasma membrane permeability in 158N and BV 2 cells. Our data support that the lipid environment affects Kv3.1b channel expression and/or functionality, and that the subsequent rupture of K+ homeostasis is relied with oligodendrocytes and microglial cells damages. PMID- 29462683 TI - Overcoming the polycation dilemma - Explorative studies to characterise the efficiency and biocompatibility of newly designed lipofection reagents. AB - In this explorative study of the novel cationic lipid OO4 in two different formulations the complex formation with DNA, the biopharmaceutical stability of the lipid/DNA complexes in physiological media, and the transfection efficiency were analysed. We investigated liposomes composed of two binary mixtures of OO4 with either DOPE or DPPE as co-lipids in the molar ratio of 1:3. These formulations were compared with regard to their ability to bind the DNA using gel retardation electrophoresis, ethidium bromide exclusion and zeta potential measurements. Colloidal stability of the lipoplexes in foetal bovine serum (FBS) and the protective effect against degradation by endonucleases were studied. Furthermore, the influence of different salt concentrations on the complex formation with DNA was examined. The DOPE mixture was markedly superior compared to the DPPE mixture. Finally, haemocompatibility studies and gene silencing experiments were performed on OO4:DOPE 1:3 (n:n). The experiments demonstrate that the lipoplex formulation OO4:DOPE 1:3 (n:n) at N/P 4 is a promising candidate for systemic application because of the high colloidal stability in serum without PEGylated lipids, high transfection efficiency, superior resistance against nucleases, reproducible complexation independent of ionic effects, and haemocompatibility. PMID- 29462684 TI - Self-microemulsifying drug delivery system for camptothecin using new bicephalous heterolipid with tertiary-amine as branching element. AB - Camptothecin (CPT) has a potent and broad-spectrum anti-tumor activity but its clinical use is limited due to its poor water solubility, stability at physiological conditions and toxicity. The aim of our study was to evaluate bicephalous heterolipid E1E for enhancing the solubility and stability of CPT through the development of a self-microemulsifying drug delivery system (SMEDDS). The solubility of CPT in heterolipid E1E was found to be 82 and 5.86 folds higher than oleic acid and ethyl oleate respectively. Molecular dynamic simulation (MDS) studies revealed that stability of hydrogen bonding between CPT with E1E contributed to solubility enhancement of CPT. SMEDDS of CPT with heterolipid E1E as an oil phase was prepared and evaluated for drug loading, droplet size, morphology, thermodynamic and long-term stability studies as per ICH guidelines. The product, CPT-SMEDDS Fc showed 1.75 mg CPT loading per 1 g of SMEDDS having a droplet size of 20.93 +/- 0.41 nm. CPT-SMEDDS Fc was found to be stable, equipotent as compared to doxorubicin and had low toxicity in HeLa, MCF-7, and HL 60 cell lines. These results signify that the delivery system, CPT-SMEDDS Fc could be a very good candidate to be considered for preclinical and clinical investigations. PMID- 29462685 TI - Topical bio(in)equivalence of metronidazole formulations in vivo. AB - The topical bioavailabilities of metronidazole from a commercially available 'reference' product (Rozex(r)) and two extemporaneous test formulations were compared. With the reference drug product, a full skin pharmacokinetic profile, in vivo in human volunteers (following a 6-h uptake and clearance over the subsequent 22 h), was obtained using an improved stratum corneum (SC) sampling procedure. Then, a two-time point SC sampling method enabled the bio(in)equivalence of the test formulations to Rozex(r) to be evaluated. One test formulation was shown to be bioequivalent to Rozex(r), both for uptake and clearance, whereas the other (more viscous and less spreadable) formulation was not. The delivery of metronidazole into the underlying viable epidermal tissue from Rozex(r) and from the equivalent test formulation was 2.5 to 3.5-fold higher than that from the inequivalent extemporaneous vehicle. The results highlight that the quantitative composition of a formulation, as well as its physical properties that influence events that take place at the vehicle-skin interface, can have a dramatic impact on the delivery of drug into the SC and subsequently to the viable skin layers below. The reproducible, sensitive and facile in vivo methodology employed may prove of particular value where regulatory approval of generic formulations lacks objective rigour. PMID- 29462686 TI - PLGA nanoformulation of sparfloxacin enhanced antibacterial activity with photoprotective potential under ambient UV-R exposure. AB - Sparfloxacin (SPFX) is a broad spectrum antibiotic which inhibits bacterial DNA gyrase enzyme activity. However, photodegradation in the presence of UVA limits its antibacterial activity and induces phototoxicity. Thus, to encounter this problem, we have developed poly d,l-lactic-co-glycolic acid (PLGA) loaded SPFX nanoparticles. Here, we have performed a comparative antibacterial activity of SPFX and its nanoparticles (NPs) through molecular docking and plate sensitivity assay. Under environmental UVA exposure, photoexcited SPFX significantly generates ROS, DNA damage and mitochondrial mediated cell death in comparison to PLGA-SPFX-NPs (nano SPFX) in human skin cell line (HaCaT). In presence of UVA, bulk SPFX induced cell cycle arrest with appearance of sub-G1 peak showing apoptosis while nano SPFX did not show any change. SPFX triggered apoptosis via alteration in membrane integrity of mitochondria and lysosome in comparison to PLGA-SPFX-NPs. Involvement of mitochondrial mediated cell death was confirmed by down-regulation of anti-apoptotic Bcl-2 and procaspase-3 and upregulation of pro apoptotic Bax, cytochrome-c and caspase-3 proteins expression. Specific caspase inhibitor, Z-VAD-FMK showed involvement of caspase cascade pathway in apoptosis. Our finding suggests that controlled release of SPFX from PLGA-SPFX-NPs can reduce its side effects and enhance its antibacterial activity. Thus, nanotization of fluoroquinolones will be a significant step to reduce the problem of resistance and phototoxicity of this group.

Despite the successful treatment of some SSTIs, those affecting the subcutaneous tissue, fascia, or muscle delay the healing process and can lead to life-threatening conditions. Therefore, more effective treatments are required to deal with such pathological situations. Recently, wound dressings loaded with antimicrobial agents emerged as viable options to reduce wound bacterial colonization and infection, in order to improve the healing process. In this review, an overview of the most prominent antibacterial agents incorporated in wound dressings along with their mode of action is provided. Furthermore, the recent advances in the therapeutic approaches used in the clinic and some future perspectives regarding antibacterial wound dressings are also discussed. PMID- 29462688 TI - Hierarchical drug release of pH-sensitive liposomes encapsulating aqueous two phase system. AB - As promising drug delivery vehicles, previous investigations of liposomes as carriers are primarily focused on insertion and modification of lipid membrane interfaces. The utility of the inner core seems to be overlooked. Herein, we developed pH-sensitive liposomes (PSLs) containing an aqueous two phase system (ATPS), and intriguingly discovered their hierarchical release under acidic stimuli. ATPS containing two polymers (poly(ethylene glycol) (PEG) and dextran) is homogeneous above phase transition temperature when producing ATPS-liposomes, and separated into PEG-rich phase and dextran-rich phase after cooling down to room temperature. The overall release time of ATPS-liposomes is divided into two stages and prolonged compared to simple aqueous liposomes. The unique release profile is due to the disproportional distribution of drugs in two phases. Doxorubicin (DOX) is loaded in the ATPS-liposomes, and their half maximum inhibition concentration on HeLa cells is 0.018 MUmol L-1, which means 27.5 fold increase in inhibition efficiency over free DOX. PMID- 29462689 TI - A hydroxyl PEG version of PEGylated liposomes and its impact on anti-PEG IgM induction and on the accelerated clearance of PEGylated liposomes. AB - Surface decoration of liposomes with polyethylene glycol (PEG), PEGylation, is recognized as a method to bestow liposomes with a prolonged circulation time following intravenous administration. However, many reports have emphasized that a first dose of PEGylated liposomes (PL) elicits an anti-PEG IgM antibody response that can trigger a rapid systemic clearance of a second dose of PL via a phenomenon that is referred to as "accelerated blood clearance (ABC)." Such a phenomenon is usually observed with PL that has been modified with methoxy-PEG. In the current study, we introduced various functional groups, methoxy (OCH3), amino (NH2), carboxyl (COOH), and hydroxyl (OH), at the chain ends of PEG to investigate the effect on anti-PEG IgM induction. Among different PEG-modified liposomes, hydroxyl PEG-modified liposomes (PL-OH) efficiently attenuated the anti-PEG IgM response in vitro. In addition, PL-OH was less recognizable by anti PEG IgM compared with other PLs. These findings raised the possibility that PL-OH could attenuate/abrogate elicitation of the ABC phenomenon. Nonetheless, upon repeated intravenous injection, PL-OH triggered the enhanced clearance of a subsequently injected second dose. Furthermore, in vitro studies have demonstrated that, as a complement activator, PL-OH is stronger than PL-OCH3 and induces further complement activation in the presence of anti-PEG IgM, which was the predominant contributor to the rapid clearance of a second dose of PL-OH. Our results suggest that the screening of complement activation by polymer-modified products in tandem with anti-polymer antibody production should be a prerequisite in the development of polymers that might enhance the therapeutic efficacy of nanocarriers. PMID- 29462690 TI - XPF plays an indispensable role in relieving silver nanoparticle induced DNA damage stress in human cells. AB - Due to the specific antimicrobial activity of silver nanoparticles (AgNPs), they are widely used in wound dressings, coatings in medical devices and household products. In spite of the well-documented genotoxicity of AgNPs, the molecular mechanisms of relieving AgNP-induced DNA damage stress remain poorly understood. We report here that one of the DNA repair factors, XPF, plays a crucial role in resisting AgNP-induced DNA damage stress in human cells. Following culture with AgNP-containing media, severely decreased colony forming abilities have been observed in XPF mutant and knockdown cells compared with wild type or control cells respectively, demonstrating that XPF is required to resist the AgNP-induced stress. By employing the comet assays, we confirmed that DNA damages were produced in all tested cells following their exposure to AgNPs for 48 h. However, more DNA damage accumulations were observed in XPF mutant and knockdown cells than wild type or control cells respectively. Moreover, severe DNA damage response and the activation of p53-mediated DNA damage response network result from mutated XPF or significantly reduced XPF level in human cells. Together, our results illustrate that XPF is the indispensable factor involved in relieving AgNP-induced DNA damage stress in human cells. PMID- 29462691 TI - Factor X activating Atractaspis snake venoms and the relative coagulotoxicity neutralising efficacy of African antivenoms. AB - Atractaspis snake species are enigmatic in their natural history, and venom effects are correspondingly poorly described. Clinical reports are scarce but bites have been described as causing severe hypertension, profound local tissue damage leading to amputation, and deaths are on record. Clinical descriptions have largely concentrated upon tissue effects, and research efforts have focused upon the blood-pressure affecting sarafotoxins. However, coagulation disturbances suggestive of procoagulant functions have been reported in some clinical cases, yet this aspect has been uninvestigated. We used a suite of assays to investigate the coagulotoxic effects of venoms from six different Atractaspis specimens from central Africa. The procoagulant function of factor X activation was revealed, as was the pseudo-procoagulant function of direct cleavage of fibrinogen into weak clots. The relative neutralization efficacy of South African Antivenom Producer's antivenoms on Atractaspis venoms was boomslang>>>polyvalent>saw-scaled viper. While the boomslang antivenom was the most effective on Atractaspis venoms, the ability to neutralize the most potent Atractaspis species in this study was up to 4-6 times less effective than boomslang antivenom neutralizes boomslang venom. Therefore, while these results suggest cross-reactivity of boomslang antivenom with the unexpectedly potent coagulotoxic effects of Atractaspis venoms, a considerable amount of this rare antivenom may be needed. This report thus reveals potent venom actions upon blood coagulation that may lead to severe clinical effects with limited management strategies. PMID- 29462692 TI - The promotion on cell growth of androgen-dependent prostate cancer by antimony via mimicking androgen activity. AB - Antimony is a widely used heavier pnictogens in industry, and its toxicity has been a matter of concern. Although previous studies have suggested that antimony may have the function as either a tumor suppressor or an oncogene in several cancers, the molecular basis underlying antimony-mediated transformation is still unclear. In the current study, we attempt to elucidate the potential role of antimony in the development of prostate cancer. Our results showed that the concentration of antimony was much higher in serum of prostate cancer patients, and was closely associated with poor outcome of patients who underwent radical prostatectomy. Additionally, low dose of antimony could promote proliferation and invasion of androgen-dependent prostate cancer cell line LNCaP cells in vitro and in vivo. The mechanistic studies demonstrated that exposure to antimony triggered the phosphorylation of androgen receptor (AR), which transcriptionally regulates the expression of androgen-related targets, including PSA and NKX3.1. Overall, our results unearthed that antimony could promote tumor growth by mimicking androgen activity in androgen-dependent prostate cancer cells. Therefore, these findings expanded our understanding on the molecular mechanism of antimony in tumorigenesis and tumor progression of prostate cancer, and it appears to be an inspiring strategy to restrain prostate cancer by inhibiting antimony-induced androgen-like effects. PMID- 29462693 TI - Two novel dual GLP-1/GIP receptor agonists are neuroprotective in the MPTP mouse model of Parkinson's disease. AB - Type 2 diabetes mellitus (T2DM) is a risk factors for developing Parkinson's disease (PD). Insulin desensitization is observed in the brains of PD patients, which may be an underlying mechanism that promotes neurodegeneration. Incretin hormones are growth factors that can re-sensitize insulin signalling. We have previously shown that analogues of the incretins GLP-1 or GIP have neuroprotective effects in the MPTP mouse model of PD. Novel dual GLP-1/GIP receptor agonists have been developed as treatments for T2DM. We have tested 3 novel dual receptor agonists DA-JC1, DA-JC4 and DA-CH5 in comparison with the GLP 1 analogue liraglutide (all drugs at 25 nmol/kg ip once-daily for 6 days) in the MPTP mouse model of PD (4 * 25 mg/kg ip). In the Rotarod and grip strength assessment, DA-CH5 performed best in reversing the MPTP-induced motor impairment. Dopamine synthesis as indicated by levels of tyrosine hydroxylase was much reduced by MPTP in the substantia nigra and striatum, and DA-CH5 was the best drug to reverse this. Pro-inflammatory cytokines were best reduced by DA-CH5, while expression levels of the neuroprotective growth factor Glial-Derived Neurotrophic Factor (GDNF) was most increased by DA-JC4. Synapses were protected best by DA-JC4 and DA-CH5. Both DA-JC1 and liraglutide showed inferior effects. These results show that a combination of GLP-1 and GIP receptor activation is more efficient compared to single GLP-1 receptor activation. We conclude that dual agonists are a promising novel treatment for PD. The GLP-1 mimetic exendin-4 has previously shown disease modifying effects in two clinical trials in Parkinson patients. PMID- 29462694 TI - Effects of pre-reproductive maternal enrichment on maternal care, offspring's play behavior and oxytocinergic neurons. AB - Potentiating social, cognitive, and sensorimotor stimulations the Environmental Enrichment (EE) increases levels of novelty and complexity experienced by individuals. Growing evidence demonstrates that parental EE experience, even occurring in the pre-reproductive phase, affects behavioral and neural developmental trajectories of the offspring. To discover how the accumulation of early maternal complex experiences may inform and shape the social behavior of the following generation, we examined the effects of pre-reproductive enrichment of dams (post-natal days 21-72) on the play performances of their male and female adolescent offspring. Furthermore, we examined the effects of pre-reproductive enrichment on maternal behavior (during post-partum days 1-10) and male intruder aggression (on post-partum day 11). Since oxytocin modulates maternal care, social bonding, and agonistic behavior, the number of oxytocinergic neurons of the paraventricular (PVN) and supraoptic (SON) nuclei was examined in both dams and offspring. Results revealed that enriched females exhibited higher levels of pup-oriented behaviors, especially Crouching, and initiated pup-retrieval more quickly than standard females after the maternal aggression test. Such behavioral peculiarities were accompanied by increased levels of oxytocinergic neurons in PVN and SON. Moreover, pre-reproductive maternal EE cross-generationally influenced the offspring according to sex. Indeed, male pups born to enriched females exhibited a reduced play fighting associated with a higher number of oxytocinergic neurons in SON in comparison to male pups born to standard-housed females. In conclusion, pre-reproductive EE to the mothers affects their maternal care and has a cross-generational impact on the social behavior of their offspring that do not directly experiences EE. PMID- 29462695 TI - A 3D intestinal tissue model supports Clostridioides difficile germination, colonization, toxin production and epithelial damage. AB - Endospore-forming Clostridioides difficile is a causative agent of antibiotic induced diarrhea, a major nosocomial infection. Studies of its interactions with mammalian tissues have been hampered by the fact that C. difficile requires anaerobic conditions to survive after spore germination. We recently developed a bioengineered 3D human intestinal tissue model and found that low O2 conditions are produced in the lumen of these tissues. Here, we compared the ability of C. difficile spores to germinate, produce toxin and cause tissue damage in our bioengineered 3D tissue model versus in a 2D transwell model in which human cells form a polarized monolayer. 3D tissue models or 2D polarized monolayers on transwell filters were challenged with the non-toxin producing C. difficile CCUG 37787 serotype X (ATCC 43603) and the toxin producing UK1 C. difficile spores in the presence of the germinant, taurocholate. Spores germinated in both the 3D tissue model as well as the 2D transwell system, however toxin activity was significantly higher in the 3D tissue models compared to the 2D transwells. Moreover, the epithelium damage in the 3D tissue model was significantly more severe than in 2D transwells and damage correlated significantly with the level of toxin activity detected but not with the amount of germinated spores. Combined, these results show that the bioengineered 3D tissue model provides a powerful system with which to study early events leading to toxin production and tissue damage of C. difficile with mammalian cells under anaerobic conditions. Furthermore, these systems may be useful for examining the effects of microbiota, novel drugs and other potential therapeutics directed towards C. difficile infections. PMID- 29462696 TI - Revealing the parasitic infection in diarrheic yaks by piloting high-throughput sequencing. AB - Diarrhea a serious disease, reported to be related with changes in microbial diversity is widely epidemic in the yaks on the Qinghai Tibet plateau. Herein, we preformed high-throughput sequencing of the parasitic diversity in 3 groups of yaks i.e. healthy adult yaks (HA), diarrheic adult yaks (DA) and diarrheic yak calves (DC) in Gannan Tibetan Autonomous Prefecture. The results showed that 2 Phyla, 3 Classes, 5 Orders, 4 Families and 6 Genera were discovered in HA yaks; 2 Phyla, 3 Classes, 6 Orders, 6 Families and 8 Genera were found in DA yaks while 2 Phyla, 5 Classes, 5 Orders, 10 Families and 7 Genera were observed in DC yaks. At Phylum level, Nematoda and Apicomplexa were detected in all three yak groups; however, Apicomplexa was found to be conspicuously higher in the DC yaks as compared to DA yaks (p < 0.05). At Class level, Litostomatea, Chromadorea and Gregarinasina were found in all three yak groups, while Spirotrichea and Colpodea were only found in the DC yaks. At Order level, Vestibuliferida, Tritrichomonadida, Rhabditida and Eugregarinorida were observed in all three yak groups; and Neogregarinorida was noted HA and DC yaks while Trichomonadida and Hypotrichomonadida were only found in DA yaks. Tritrichomonadida was found to be relatively higher in the DA yaks when compared with HA yaks (p < 0.05) and DC yaks (p < 0.05). At Family level, Simplicimonadidae and Haemonchidae were found in all three yak groups. Trichostrongylidae was observed in both HA and DA yak groups. Syncystidae was established in both HA and DC yak groups except DA yaks. Trichomonadidae and Dictyocaulidae were only found in DA yaks. Plectidae, Strongylidae, Echinamoebidae, Lecudinidae, Pseudokeronopsidae and Panagrolaimidae were only discovered in DC yaks. Simplicimonadidae was found to be remarkably higher in DA yaks as compared to HA and DC yak groups (p < 0.05); and Haemonchidae was detected at higher levels in HA yaks as compared to DA and DC yaks (p < 0.05). At Genus level, Entamoeba, Buxtonella and Haemonchus were found in all three yak groups. Plectus and Echinamoeba were only found in DC yaks; while Trichostrongylus and Trepomonas were observed in HA and DA yak groups. The genus Gregarina was found in both diarrheic yak groups; while the genera of Tetratrichomonas and Dictyocaulus were observed in DA yaks only. The present study herein reported an insight of the change of parasitic diversity in diarrheic yaks at high altitude area, which shall make contribution towards the solid prevention of diarrhea in yaks. PMID- 29462697 TI - Effect of Mycobacterium tuberculosis Rv3717 on cell division and cell adhesion. AB - Mycobacterium tuberculosis Rv3717 has been identified as a zinc-dependent amidase which can hydrolyze peptidoglycan (PG). To demonstrate the relationship of Rv3717 and cell division, in this study, Rv3717 gene was first amplified and expressed and the resulting protein was purified by using a His-tagged approach. M. smegmatis mc2155, a fast-growing and nonpathogenic mycobacterium was used to evaluate the effect of Rv3717 on cell division. Scan electron microscope (SEM) results indicated that M. smegmatis with division site was more exhibited and some of the cells turned larger in size after Rv3717 treatment. Transmission electron microscope (TEM) results revealed that MSMEG_6281 gene knockout strain named M sm-DeltaM_6281 (MSMEG_6281 in M. smegmatis mc2155 is the homologous gene of Rv3717) tended to have a division defect with a severely abnormal morphology, and division septa were distorted. Gene expression analysis indicated also that the gene involved in cell division such as M. smegmatis ftsZ was significantly up regulated with treatment time. The findings demonstrated that physiological role of Rv3717 was related to cell division and regulated possibly division septum formation. Further, fibronectin (Fn) binding ability of Rv3717 was evaluated by protein binding experiment, and the results confirmed the interaction of Rv3717 with Fn in a dose dependent manner. We found also that the invasion rate of M. sm DeltaM_6281 to A549 cells was reduced by 59% compared to the control strain, and the invasion defect could be rescued by Rv3717 addition. RT-PCR results showed that M. smegmatis fbpC were up-regulated after Rv3717 addition. These clues may be significant to explore roles of Rv3717 in growth and colonization of mycobacteria. PMID- 29462698 TI - Piper sarmentosum Roxb. confers neuroprotection on beta-amyloid (Abeta)-induced microglia-mediated neuroinflammation and attenuates tau hyperphosphorylation in SH-SY5Y cells. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Piper sarmentosum Roxb. (PS), belonging to Piperaceae family, is an edible plant with medicinal properties. It is traditionally used by the Malays to treat headache and boost memory. Pharmacological studies revealed that PS exhibits anti-inflammatory, anti oxidant, anti-acetylcholinesterase, and anti-depressant-like effects. In view of this, the present study aimed to investigate the anti-inflammatory actions of PS and its potential neuroprotective effects against beta-amyloid (Abeta)-induced microglia-mediated neurotoxicity. MATERIALS AND METHODS: The inhibitory effects of hexane (LHXN), dichloromethane (LDCM), ethyl acetate (LEA) and methanol (LMEOH) extracts from leaves of PS on Abeta-induced production and mRNA expression of pro-inflammatory mediators in BV-2 microglial cells were assessed using colorimetric assay with Griess reagent, ELISA kit and real-time RT-PCR respectively. Subsequently, MTT reduction assay was used to evaluate the neuroprotective effects of PS leaf extracts against Abeta-induced microglia mediated neurotoxicity in SH-SY5Y neuroblastoma cells. The levels of tau proteins phosphorylated at threonine 231 (pT231) and total tau proteins (T-tau) were determined using ELISA kits. RESULTS: Polar extracts of PS leaves (LEA and LMEOH) reduced the Abeta-induced secretion of pro-inflammatory cytokines (IL-1beta and TNF-alpha) in BV-2 cells by downregulating the mRNA expressions of pro inflammatory cytokines. The inhibition of nitric oxide (NO) production could be due to the free radical scavenging activity of the extracts. In addition, conditioned media from Abeta-induced BV-2 cells pre-treated with LEA and LMEOH protected SH-SY5Y cells against microglia-mediated neurotoxicity. Further mechanistic study suggested that the neuroprotective effects were associated with the downregulation of phosphorylated tau proteins. CONCLUSIONS: The present study suggests that polar extracts of PS leaves confer neuroprotection against Abeta induced microglia-mediated neurotoxicity in SH-SY5Y cells by attenuating tau hyperphosphorylation through their anti-inflammatory actions and could be a potential therapeutic agent for Alzheimer's disease. PMID- 29462699 TI - Effect of Eucommia ulmoides Oliv., Gynostemma pentaphyllum (Thunb.) Makino, and Curcuma longa L. on Th1- and Th2-cytokine responses and human leukocyte antigen DR expression in peripheral blood mononuclear cells of septic patients. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Many traditional Chinese medicines (TCM), such as Eucommia ulmoides Oliv., Gynostemma pentaphyllum (Thunb.) Makino, and Curcuma longa L., have been reported to have various immune-modulatory effects. AIM OF THE STUDY: To determine the effects of extracts from these three TCM on type 1 T help (Th1)- and Th2-cytokine responses and human leukocyte antigen (HLA)-DR expression in peripheral blood mononuclear cells (PBMCs) obtained from septic patients. MATERIALS AND METHODS: Lipopolysaccharide (LPS)-stimulated PBMCs of healthy controls and septic patients were cultured for 48 hs with or without 0.05/0.1 mg/ml of TCM extract. HLA-DR expression in monocytes was detected using flow cytofluorimetry. The interferon [IFN]-gamma, tumor necrosis factor [TNF] alpha, interleukin (IL)- 2, IL-5, IL-10, and IL-13 levels in supernatants were measured with a human enzyme-linked immunosorbent assay. RESULTS: Treatment with either 0.05 or 0.1 mg/ml of C. longa L. extract significantly restored the percentage of HLA-DR-positive monocytes, which was decreased by LPS in control and patient groups. Treatment with 0.05 or 0.1 mg/ml E. ulmoides Oliv. and C.longa L. extract decreased IL-10 production from LPS-stimulated PBMCs of controls and patients. In patients with sepsis, C. longa L. extract decreased IL 10 production to a greater degree than did E. ulmoides Oliv extract. Although IFN gamma, TNF-alpha, or IL-13 productions from LPS-stimulated PBMCs were influenced by E. ulmoides Oliv., G. pentaphyllum (Thunb.) Makino, or C. longa L. in control or sepsis groups in this study, only the influence of IL-10 was consistent in both control and sepsis groups. CONCLUSIONS: By enhancing monocyte HLA-DR expression and decreasing IL-10 production, C. longa L. might help restore inflammatory responses in septic patients to eradicate pathogens. PMID- 29462700 TI - Eugenia brasiliensis leaves extract attenuates visceral and somatic inflammatory pain in mice. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Eugenia brasiliensis Lam. (Myrtaceae) is a Brazilian tree distributed throughout Atlantic rain forest, since Bahia until Santa Catarina state, and is popularly known as "grumixaba, grumixameira, cumbixaba, ibaporoiti, and cereja-brasileira". The bark and leaves of Eugenia brasiliensis are used in folk medicine as adstringent, diuretic, energizing, anti rheumatic and anti-inflammatory. This study aimed at investigating the chemical composition, antinociceptive and anti-inflammatory effect of the hydroalcoholic extract of Eugenia brasiliensis (HEEb). MATERIAL AND METHODS: Chemical composition of the HEEb was determined by High Performance Liquid Chromatography/ESI-Mass Spectrometry (HPLC-ESI-MS/MS). The antinociceptive and anti-inflammatory effects of HEEb (30-300 mg/kg) was verified in mice after oral administration by intra-gastric gavage (i.g.) 60 min prior to experimentation. It was investigated whether HEEb decreases visceral pain and leukocyte migration induced by an intraperitoneal (i.p.) injection of acetic acid (0.6%). We also evaluated whether HEEb decreases nociceptive behavior induced by formalin (including paw edema and temperature), prostaglandin E2 (PGE2), histamine, and compound 48/80. Finally, we evaluated the effect of HEEb in the chronic inflammatory (mechanical and thermal hypersensitivity) pain induced by complete Freund's adjuvant (CFA), as well as quantifying the concentration of the pro inflammatory cytokines TNF-alpha and IL-6 in the paw by ELISA method. RESULTS: Seven polyphenols were identified in HEEb by HPLC-ESI-MS/MS analysis. HEEb treatment alleviated nocifensive behavior and leukocyte migration caused by acetic acid. Moreover, HEEb also reduced the inflammatory pain and paw temperature induced by formalin, as well as it decreased nociceptive behavior induced by histamine and compound 48/80. Finally, acute and repeated treatment of animals with HEEb (100 mg/kg, i.g.) markedly reduced the mechanical and thermal (heat) hypersensitivity, besides decrease paw edema and temperature induced by CFA, and this effect was evident until the day 7. Moreover, repeated treatment with HEEb (100 mg/kg, i.g.) significantly reduced the levels of IL-6 and TNF alpha in the paw when compared to the CFA group. CONCLUSIONS: This is the first report showing that HEEb presents antinociceptive and anti-inflammatory effects in the visceral and somatic inflammatory pain in mice, possibly involving the inhibition of histamine receptors and pro-inflammatory cytokines activated pathways. Our results are of interest because they support the use of Eugenia brasiliensis as a potential source of phytomedicine for inflammatory diseases and pain. PMID- 29462701 TI - Quantitative Comparison Of Vesicular Glutamate Transporters in rat Deep Cerebellar Nuclei. AB - The excitatory synapses of the rat deep cerebellar nuclei (DCN) were quantitatively analyzed by vesicular glutamate transporter 1 and 2 (vGluT1 and vGluT2) immunolabeling. We calculated the number and sizes of the labeled boutons and compared them between lateral/dentate nucleus (LN/DN), posterior interposed nucleus (PIN), anterior interposed nucleus (AIN), and medial nucleus (MN). The density of vGluT1+ boutons differs significantly within these nuclei. In contrast, the vGluT2+ bouton density is more similar between different nuclei. The phylogenetically newer DCN (LN/DN and PIN) have a 39% higher density of vGluT1+ boutons than the phylogenetically older DCN (AIN and MN). The volume of vGluT1+ boutons does not differ between the DCN, however the average volume of vGluT2+ boutons is larger in MN. In summary, our current results confirm and extend our previous findings showing that the increase in dendritic and axonal wiring in phylogenetically newer DCN is associated with an increase in vGluT1+ bouton density. PMID- 29462703 TI - Lifelong Aerobic Exercise Reduces the Stress Response in Rats. AB - The aim of this study was to analyze the effects of lifelong aerobic exercise (AE) on the adaptive response of the stress system in rats. It is well known that hypothalamic-pituitary-adrenal axis (HPA) activity differs when triggered by voluntary or forced exercise models. Male Wistar rats belonging to exercise (E) or control (C) groups were subjected to chronic AE, and two cutoff points were established at 8 (middle age) and 18 months (old age). Behavioral, biochemical and histopathological studies were performed on the main components/targets of the stress system. AE increased adrenal sensitivity (AS), brain corticosterone (CORT) and corticotropin-releasing factor (CRF), but had no effect on the thymus, adrenal glands (AGs) weight or plasma CORT. In addition, AE exerted no effect on the sympathetic tone, but significantly reduced anxiety-related behavior and emotionality. Aging decreased AS and deregulated neuroendocrine feedback, leading to an anxiogenic state which was mitigated by AE. Histopathological and morphometric analysis of AGs showed no alterations in middle-aged rats but adrenal vacuolization in approximately 20% old rats. In conclusion, lifelong AE did not produce adverse effects related to a chronic stress state. On the contrary, while AE upregulated some components of the HPA axis, it generated an adaptive response to cumulative changes, possibly through different compensatory and/or super compensatory mechanisms, modulated by age. The long-term practice of AE had a strong positive impact on stress resilience so that it could be recommended as a complementary therapy in stress and depression disease. PMID- 29462702 TI - Cell Type-specific Intrinsic Perithreshold Oscillations in Hippocampal GABAergic Interneurons. AB - The hippocampus plays a critical role in learning, memory, and spatial processing through coordinated network activity including theta and gamma oscillations. Recent evidence suggests that hippocampal subregions (e.g., CA1) can generate these oscillations at the network level, at least in part, through GABAergic interneurons. However, it is unclear whether specific GABAergic interneurons generate intrinsic theta and/or gamma oscillations at the single-cell level. Since major types of CA1 interneurons (i.e., parvalbumin-positive basket cells (PVBCs), cannabinoid type 1 receptor-positive basket cells (CB1BCs), Schaffer collateral-associated cells (SCAs), neurogliaform cells and ivy cells) are thought to play key roles in network theta and gamma oscillations in the hippocampus, we tested the hypothesis that these cells generate intrinsic perithreshold oscillations at the single-cell level. We performed whole-cell patch-clamp recordings from GABAergic interneurons in the CA1 region of the mouse hippocampus in the presence of synaptic blockers to identify intrinsic perithreshold membrane potential oscillations. The majority of PVBCs (83%), but not the other interneuron subtypes, produced intrinsic perithreshold gamma oscillations if the membrane potential remained above -45 mV. In contrast, CB1BCs, SCAs, neurogliaform cells, ivy cells, and the remaining PVBCs (17%) produced intrinsic theta, but not gamma, oscillations. These oscillations were prevented by blockers of persistent sodium current. These data demonstrate that the major types of hippocampal interneurons produce distinct frequency bands of intrinsic perithreshold membrane oscillations. PMID- 29462704 TI - Enhancement of Endocannabinoid-dependent Depolarization-induced Suppression of Excitation in Glycinergic Neurons by Prolonged Exposure to High Doses of Salicylate. AB - The Dorsal Cochlear Nucleus (DCN) is a region which has been traditionally linked to the genesis of tinnitus, the constant perception of a phantom sound. Sodium salicylate, a COX-2 inhibitor, can induce tinnitus in high doses. Hyperactivity of DCN neurons is observed in several animal models of tinnitus, including salicylate-induced tinnitus. The DCN presents several forms of endocannabinoid (EC)-dependent synaptic plasticity and COX-2 can also participate in the oxidative degradation of ECs. We recently demonstrated that short-term perfusion of sodium salicylate and other inhibitors of both oxidative and hydrolytic EC degradation did not affect depolarization-induced suppression of excitation (DSE), a form of EC-dependent short-term synaptic plasticity. Here, we show that prolonged incubation with high doses of sodium salicylate (1.4 mM) enhances DSE of synapses onto glycinergic DCN interneurons but not those innervating glutamatergic DCN fusiform neurons. This effect was not reproduced with lower doses of salicylate (140 uM) or with ibuprofen, another inhibitor of COX-2. This effect was not observed in the presence of AM251, an antagonist/inverse agonist of cannabinoid CB1 receptors, showing that it was dependent on EC release. Finally we demonstrated that incubation with salicylate potentiated the increase in intracellular calcium during the depolarization. Our results point to an increased inhibition of DCN inhibitory CW neuron during depolarizations, probably by an enhanced EC release during the depolarizations, which is potentially significant for DCN hyperactivity and tinnitus generation. PMID- 29462705 TI - Nitric Oxide and Mitochondrial Function in Neurological Diseases. AB - Mitochondria are key cellular organelles that play crucial roles in the energy production and regulation of cellular metabolism. Accumulating evidence suggests that mitochondrial activity can be modulated by nitric oxide (NO). As a key neurotransmitter in biologic systems, NO mediates the majority of its function through activation of the cyclic guanylyl cyclase (cGC) signaling pathway and S nitrosylation of a variety of proteins involved in cellular functioning including those involved in mitochondrial biology. Moreover, excess NO or the formation of reactive NO species (RNS), e.g., peroxynitrite (ONOO-), impairs mitochondrial functioning and this, in conjunction with nuclear events, eventually affects neuronal cell metabolism and survival, contributing to the pathogenesis of several neurodegenerative diseases. In this review we highlight the possible mechanisms underlying the noxious effects of excess NO and RNS on mitochondrial function including (i) negative effects on electron transport chain (ETC); (ii) ONOO--mediated alteration in mitochondrial permeability transition; (iii) enhanced mitochondrial fragmentation and autophagy through S-nitrosylation of key proteins involved in this process such as dynamin-related protein 1 (DRP-1) and Parkin/PINK1 (protein phosphatase and tensin homolog-induced kinase 1) complex; (iv) alterations in the mitochondrial metabolic pathways including Krebs cycle, glycolysis, fatty acid metabolism, and urea cycle; and finally (v) mitochondrial ONOO--induced nuclear toxicity and subsequent release of apoptosis-inducing factor (AIF) from mitochondria, causing neuronal cell death. These proposed mechanisms highlight the multidimensional nature of NO and its signaling in the mitochondrial function. Understanding the mechanisms by which NO mediates mitochondrial (dys)function can provide new insights into the treatment of neurodegenerative diseases.

We have previously demonstrated that spinal cord matrix (SCM) proteins and hyaluronic acid (HA) nanofibers mitigate chondroitin sulfate proteoglycan (CSPG) inhibition and promote growth in peripheral neurons. In this study, we evaluated the effects of a characteristic CSPG, chondroitin sulfate A (CSA), SCM, and HA fibers on macrophages and Schwann cells (SCs). We hypothesized that our cues would accelerate the macrophages' return to rest following classical activation (M1/pro inflammatory) with lipopolysaccharide (LPS; 1 MUg/mL) and would accelerate the transformation of SCs from an immature state following injury to a mature/pro myelinating phenotype. LPS stimulation of the macrophages caused upregulation of inducible nitric oxide synthase (iNOS; M1 gene) and led to significantly increased cell area and decreased circularity. However, the SCM and HA nanofibers mitigated this effect, significantly reducing iNOS expression. SCs on the fibers had significantly reduced area and increased elongation. These morphological changes may have polarized the cells leading to decreased GFAP (immature gene) and increased Oct6 and Krox 20 (promyelin genes) expression. Antibody arrays were used to measure relative levels of inflammatory cytokines released by the cells. The arrays confirmed that anti-inflammatory cytokines are released from the cells when cultured with our biomaterial cues and helped identify targets for future investigation including vascular endothelial growth factor (VEGF), interleukin (IL)-10, monocyte colony stimulating factor (M-CSF) from the macrophages, Agrin, ciliary neurotrophic factor (CNTF), tissue inhibitor metalloproteinases (TIMPs)-1 from SCs, and IL-2 from both cell types. In conclusion, these results suggest that our biomaterial cues have pro-regenerative effects on both cell types and if combined may trigger cells toward regenerative programs. PMID- 29462707 TI - The Diagnostic Value of Anti-Mullerian Hormone in Early Post Menarche Adolescent Girls with Polycystic Ovarian Syndrome. AB - STUDY OBJECTIVE: Polycystic ovarian syndrome (PCOS) is a common endocrine disorder characterized by hyperandrogenism and chronic anovulation, which affects 5%-10% of reproductive-age women. Diagnosis of adult patients with PCOS is made easily with clinical and laboratory methods and the anti-Mullerian hormone (AMH) level are accepted as a good indicator. However, there is still no complete consensus on the diagnosis of PCOS in adolescents. DESIGN AND SETTING: Prospective cohort study, December 2013 to November 2014. PARTICIPANTS: The study was conducted on adolescent girls with oligomenorrhea, with at least 2 years since menarche. The study group consisted of adolescent girls with complete PCOS and incomplete PCOS. A control group was formed of healthy adolescent girls. Complete PCOS was diagnosed according to the Rotterdam criteria, as the presence of all the following characteristics: oligomenorrhea, hyperandrogenism, and polycystic ovarian morphology on ultrasound image. Incomplete PCOS was accepted as "oligomenorrhea and polycystic ovarian morphology," or "oligomenorrhea and hyperandrogenism." INTERVENTIONS AND MAIN OUTCOME MEASURES: All patients underwent a physical examination and the anthropometric assessments, insulin resistance, and acanthosis nigricans were recorded. It was also noted whether or not the patient had an acne score. The Ferriman-Gallwey score was applied to evaluate hirsutism. RESULTS: The results of this study showed that no statistically significant difference was found between the PCOS and incomplete PCOS groups and the control group with respect to AMH levels. CONCLUSION: The use of adult-specific diagnostic methods in adolescence might result in an incomplete diagnosis and inadequate treatment plan. Although the serum AMH level clearly facilitates the diagnosis of PCOS, the use of the AMH level in adolescence in PCOS diagnosis is still controversial and further studies are needed. PMID- 29462708 TI - Diversity of Pubertal Development in Cartilage-Hair Hypoplasia; Two Illustrative Cases. AB - BACKGROUND: Cartilage-hair hypoplasia (CHH) is a rare chondrodysplasia, including disproportionate short stature, hypoplastic hair, immunodeficiency, and increased risk of malignancies. Absent pubertal growth spurt and absent pubic hair complicate monitoring of pubertal development in these patients. CASES: Two CHH patients with delayed puberty and excessive growth failure are described. One of the girls had hypogonadotropic hypogonadism whereas the other had hyponormogonadotropic hypogonadism with no spontaneous pubertal development and slow response to estrogen therapy, both requiring permanent replacement therapy. SUMMARY AND CONCLUSION: Careful follow-up of pubertal development in individuals with CHH and other growth-restricting bone diseases is needed. In delayed pubertal development timely hormone therapy is essential to ensure maximal growth and well developed secondary sex characteristics. PMID- 29462710 TI - Fibrin glue mesh fixation combined with mesenchymal stem cells or exosomes modulates the inflammatory reaction in a murine model of incisional hernia. AB - : Surgical meshes are effective and frequently used to reinforce soft tissues. Fibrin glue (FG) has been widely used for mesh fixation and is also considered an optimal vehicle for stem cell delivery. The aim of this preclinical study was to evaluate the therapeutic effect of MSCs and their exosomes combined with FG for the treatment of incisional hernia. A murine incisional hernia model was used to implant surgical meshes and different treatments with FG, MSCs and exo-MSCs were applied. The implanted meshes were evaluated at day 7 by anatomopathology, cellular analysis of infiltrating leukocytes and gene expression analysis of TH1/TH2 cytokines, MMPs, TIMPs and collagens. Our results demonstrated a significant increase of anti-inflammatory M2 macrophages and TH2 cytokines when MSCs or exo-MSCs were used. Moreover, the analysis of MMPs, TIMPs and collagen exerted significant differences in the extracellular matrix and in the remodeling process. Our in vivo study suggests that the fixation of surgical meshes with FG and MSCs or exo-MSCs will have a beneficial effect for the treatment of incisional hernia in terms of improved outcomes of damaged tissue, and especially, in the modulation of inflammatory responses towards a less aggressive and pro-regenerative profile. STATEMENT OF SIGNIFICANCE: The implantation of surgical meshes is the standard procedure to reinforce tissue defects such as hernias. However, an exacerbated and persistent inflammatory response secondary to this implantation is frequently observed, leading to a strong discomfort and chronic pain in the patients. In many cases, an additional surgical intervention is needed to remove the mesh. This study shows that mesenchymal stem cells and their exosomes, combined with a fibrin sealant, can be used for the successful fixation of these meshes. This new therapeutic approach, assayed in a murine model of incisional hernia, favors the modulation of the inflammatory response towards a less aggressive and pro-regenerative profile. PMID- 29462709 TI - Postinsertional Pain after Intrauterine Device Placement among Nulliparous Adolescents. AB - STUDY OBJECTIVE: To quantify the "normal" adolescent experience after intrauterine device insertion, to provide appropriate counseling for future adolescents. DESIGN: Prospective cohort study. SETTING: Marshall University Department of Obstetrics and Gynecology generalist and adolescent gynecology clinics. PARTICIPANTS: Nulliparous adolescents age 13-18 years and parous adults 18 years of age or older who received a levonorgestrel intrauterine system (LNG IUS). INTERVENTIONS: Visual analogue scale (VAS) pain score and medication log was used for data collection for 2 weeks after LNG-IUS insertion. A separate chart review was completed for demographic factors and indications for procedure. MAIN OUTCOME MEASURES: VAS pain scores and medication use was compared between groups. RESULTS: Ninety-three subjects returned the VAS record and medication log (46 adolescents and 47 adults). There was no difference in the incidence of endometriosis or dysmenorrhea, but there was a higher prevalence of menorrhagia among adolescents (30/46, 65.2% vs 10/47, 21.3%; P < .001). Forty-five of forty seven (95.7%) adults vs 25/46 (54.3%) adolescents had contraception as an indication for intrauterine device use (P < .001). Pain scores were statistically higher among the adolescent group each day (P < .05) in the 2-week study period. The greatest mean differences occurred in the first 4 days. More adolescents (15/46, 32.6%) than adults (6/47, 12.8%) had a pain score greater than 5 during the first 3 days (P = .022). A statistical difference in amount of ibuprofen recorded was only noted on day 1 (P = .023) and day 4 (P = .046). CONCLUSION: Nulliparous adolescents who undergo LNG-IUS placement experience more postinsertional discomfort compared with parous adults; however, this method should still be considered first-line treatment in this age group. PMID- 29462711 TI - Exogenous mineralization of hard tissues using photo-absorptive minerals and femto-second lasers; the case of dental enamel. AB - : A radical new methodology for the exogenous mineralization of hard tissues is demonstrated in the context of laser-biomaterials interaction. The proposed approach is based on the use of femtosecond pulsed lasers (fs) and Fe3+-doped calcium phosphate minerals (specifically in this work fluorapatite powder containing Fe2O3 nanoparticles (NP)). A layer of the synthetic powder is applied to the surface of eroded bovine enamel and is irradiated with a fs laser (1040 nm wavelength, 1 GHz repetition rate, 150 fs pulse duration and 0.4 W average power). The Fe2O3 NPs absorb the light and may act as thermal antennae, dissipating energy to the vicinal mineral phase. Such a photothermal process triggers the sintering and densification of the surrounding calcium phosphate crystals thereby forming a new, dense layer of typically ~20 MUm in thickness, which is bonded to the underlying surface of the natural enamel. The dispersed iron oxide NPs, ensure the localization of temperature excursion, minimizing collateral thermal damage to the surrounding natural tissue during laser irradiation. Simulated brushing trials (pH cycle and mechanical force) on the synthetic layer show that the sintered material is more acid resistant than the natural mineral of enamel. Furthermore, nano-indentation confirms that the hardness and Young's modulus of the new layers are significantly more closely matched to enamel than current restorative materials used in clinical dentistry. Although the results presented herein are exemplified in the context of bovine enamel restoration, the methodology may be more widely applicable to human enamel and other hard-tissue regenerative engineering. STATEMENT OF SIGNIFICANCE: In this work we provide a new methodology for the mineralisation of dental hard tissues using femtosecond lasers and iron doped biomaterials. In particular, we demonstrate selective laser sintering of an iron doped fluorapatite on the surface of eroded enamel under low average power and mid-IR wavelength and the formation of a new layer to substitute the removed material. The new layer is evaluated through simulated brushing trials and nano-indentation. From the results we can conclude that is more acid resistant than natural enamel while, its mechanical properties are superior to that of current restorative materials. To the best of our knowledge this is the first time that someone demonstrated, laser sintering and bonding of calcium phosphate biomaterials on hard tissues. Although we here we discuss the case of dental enamel, similar approach can be adopted for other hard tissues, leading to new strategies for the fixation of bone/tooth defects. PMID- 29462713 TI - Which spike train distance is most suitable for distinguishing rate and temporal coding? AB - BACKGROUND: It is commonly assumed in neuronal coding that repeated presentations of a stimulus to a coding neuron elicit similar responses. One common way to assess similarity are spike train distances. These can be divided into spike resolved, such as the Victor-Purpura and the van Rossum distance, and time resolved, e.g. the ISI-, the SPIKE- and the RI-SPIKE-distance. NEW METHOD: We use independent steady-rate Poisson processes as surrogates for spike trains with fixed rate and no timing information to address two basic questions: How does the sensitivity of the different spike train distances to temporal coding depend on the rates of the two processes and how do the distances deal with very low rates? RESULTS: Spike-resolved distances always contain rate information even for parameters indicating time coding. This is an issue for reasonably high rates but beneficial for very low rates. In contrast, the operational range for detecting time coding of time-resolved distances is superior at normal rates, but these measures produce artefacts at very low rates. The RI-SPIKE-distance is the only measure that is sensitive to timing information only. COMPARISON WITH EXISTING METHODS: While our results on rate-dependent expectation values for the spike resolved distances agree with Chicharro et al. (2011), we here go one step further and specifically investigate applicability for very low rates. CONCLUSIONS: The most appropriate measure depends on the rates of the data being analysed. Accordingly, we summarize our results in one table that allows an easy selection of the preferred measure for any kind of data. PMID- 29462712 TI - Macrophage involvement affects matrix stiffness-related influences on cell osteogenesis under three-dimensional culture conditions. AB - : Accumulating evidence indicates that the physicochemical properties of biomaterials exert profound influences on stem cell fate decisions. However, matrix-based regulation selected through in vitro analyses based on a given cell population do not genuinely reflect the in vivo conditions, in which multiple cell types are involved and interact dynamically. This study constitutes the first investigation of how macrophages (Mphis) in stiffness-tunable transglutaminase cross-linked gelatin (TG-gel) affect the osteogenesis of bone marrow-derived mesenchymal stem cells (BMMSCs). When a single cell type was cultured, low-stiffness TG-gels promoted BMMSC proliferation, whereas high stiffness TG-gels supported cell osteogenic differentiation. However, Mphis in high-stiffness TG-gels were more likely to polarize toward the pro-inflammatory M1 phenotype. Using either conditioned medium (CM)-based incubation or Transwell based co-culture, we found that Mphis encapsulated in the low-stiffness matrix exerted a positive effect on the osteogenesis of co-cultured BMMSCs. Conversely, Mphis in high-stiffness TG-gels negatively affected cell osteogenic differentiation. When both cell types were cultured in the same TG-gel type and placed into the Transwell system, the stiffness-related influences of Mphis on BMMSCs were significantly altered; both the low- and high-stiffness matrix induced similar levels of BMMSC osteogenesis. Although the best material parameter for synergistically affecting Mphis and BMMSCs remains unknown, our data suggest that Mphi involvement in the co-culture system alters previously identified material-related influences on BMMSCs, such as matrix stiffness related effects, which were identified based on a culture system involving a single cell type. Such Mphi-stem cell interactions should be considered when establishing proper matrix parameter-associated cell regulation in the development of biomimetic biomaterials for regenerative applications. STATEMENT OF SIGNIFICANCE: The substrate stiffness of a scaffold plays critical roles in modulating both reparative cells, such as mesenchymal stem cells (MSCs), and immune cells, such as macrophages (Mphis). Although the influences of material stiffness on either Mphis or MSCs, have been extensively described, how the two cell types respond to matrix cues to dynamically affect each other in a three dimensional (3D) biosystem remains largely unknown. Here, we report our findings that, in a platform wherein Mphis and bone marrow-derived MSCs coexist, matrix stiffness can influence stem cell fate through both direct matrix-associated regulation and indirect Mphi-based modulation. Our data support future studies of the MSC-Mphi-matrix interplay in the 3D context to optimize matrix parameters for the development of the next biomaterial. PMID- 29462714 TI - Alterations of conjunctival glycocalyx and microcirculation in non-septic critically ill patients. AB - As of now the relationship between glycocalyx degradation and microcirculatory perfusion abnormalities in non-septic critical ill patients is unclear. In addition, conjunctival sidestream dark field-imaging for the purpose of glycocalyx thickness estimation has never been performed. We aimed to investigate whether changes in glycocalyx thickness in non-septic patients are associated with microcirculatory alterations in conjunctival and sublingual mucosa. In this single-centre prospective observational study, using techniques for direct in vivo observation of the microcirculation, we performed a single measurement of microcirculatory perfusion parameters and visualized glycocalyx thickness in both ocular conjunctiva and sublingual mucosa in mixed cardio surgical (n = 18) and neurocritical patients (n = 27) and compared these data with age-matched healthy controls (n = 20). In addition we measured systemic syndecan-1 levels. In the sublingual and conjunctival region we observed a significant increase of the perfused boundary region (PBR) in both neuro-critical and cardiac surgical ICU patients, compared to controls. There was a significant increase of syndecan-1 in ICU patients comparing with controls and in cardiac patients comparing with neurological (120.0[71.0-189.6] vs. 18.0[7.2-40.7], p < 0.05). We detected a weak correlation between syndecan-1 and sublingual PBR but no correlations between global glycocalyx damage and conjuctival glycocalyx thickness. We found significantly lower perfused vessel density (PVD) of small vessels in sublingual mucosa in patients after cardiac surgery in comparison with healthy subjects. In neuro-critical, but not cardiac surgery patients conjunctival TVD and PVD of small vessels were found to be significantly lower in comparison with controls. PMID- 29462715 TI - A new model of diabetic nephropathy in C57BL/6 mice challenged with advanced oxidation protein products. AB - There remains a lack of robust mouse models with key features of advanced human diabetic nephropathy (DN). Few options of murine models of DN require mutations to be superimposed to obtain desired phenotypic characteristics. Most genetically modified mice are on the C57BL/6 background; however, they are notorious for resistance to develop DN. To overcome these conundrums, this study reports a novel DN model by challenging with advanced oxidation protein products (AOPPs) in streptozotocin-induced diabetic C57BL/6 mice. AOPPs-challenged diabetic C57BL/6 mice were more sensitive to develop progressive proteinuria, causing a 5.59-fold increase in urine albumin to creatinine ratio as compared to diabetic controls by 24 weeks. Typical lesions were present as demonstrated by significant diffuse mesangial expansion, diffuse podocyte foot process effacement, increased glomerular basement membrane thickness, focal arteriolar hyalinosis, mesangiolysis, and mild interstitial fibrosis. These changes were alleviated by losartan treatment. Collectively, these results suggest that AOPPs can accelerate the progression of DN in the resistant C57BL/6 mouse strain. Our studies offer a novel model for studying the pathogenesis of DN that resembles human diabetic kidney disease. It also makes it possible to interrogate the role of specific genetic modifications and to evaluate novel therapeutics to treat DN in preclinical setting. PMID- 29462716 TI - Macrophage-derived superoxide production and antioxidant response following skeletal muscle injury. AB - Macrophages are key players of immunity that display different functions according to their activation states. In a regenerative context, pro-inflammatory macrophages (Ly6Cpos) are involved in the mounting of the inflammatory response whereas anti-inflammatory macrophages (Ly6Cneg) dampen the inflammation and promote tissue repair. Reactive oxygen species (ROS) production is a hallmark of tissue injury and of subsequent inflammation as described in a bacterial challenge context. However, whether macrophages produce ROS following a sterile tissue injury is uncertain. In this study, we used complementary in vitro, ex vivo and in vivo experiments in mouse to show that macrophages do not release ROS following a sterile injury in skeletal muscle. Furthermore, expression profiles of genes involved in the response to oxidative stress in Ly6Cpos and Ly6Cneg macrophage subsets did not indicate any antioxidant response in this context. Finally, in vivo, pharmacological antioxidant supplementation with N-Acetyl cysteine (NAC) following skeletal muscle injury did not alter macrophage phenotype during skeletal muscle regeneration. Overall, these results indicate that following a sterile injury, macrophage-derived ROS release is not involved in the regulation of the inflammatory response in the regenerating skeletal muscle. PMID- 29462717 TI - Evaluating the impact of diabetes and diabetic cardiomyopathy rat heart on the outcome of ischemia-reperfusion associated oxidative stress. AB - Earlier literature underlines that oxidative stress plays a major role in the pathology of myocardial ischemia-reperfusion (I/R) injury, diabetic cardiomyopathy (DCM), diabetes mellitus (DM), fibrosis and hypertrophy which could adversely affect the normal cardiac function. However, the contributory role of oxidative stress in I/R pathology of heart with pre-existing abnormalities or diseases like DM and DCM remains to be explored. I/R injury was induced in normal (normal diet), DM (normal diet + streptozotocin: multiple low dose of 30 mg/kg) and DCM (high fat diet (40% fat) + streptozotocin: multiple low dose of 30 mg/kg) rat hearts using Langendorff isolated heart perfusion apparatus. Cardiac physiological recovery after I/R was assessed by hemodynamic parameters like LVDP, and LVSP, whereas cardiac injury was measured by tissue infarct size, and apoptosis, LDH, and CK release in coronary effluent. The oxidative stress was evaluated in myocardial homogenate, mitochondrial subpopulation, and microsomes. Reperfusing the ischemic DCM heart significantly deteriorated cardiac physiological recovery and elevated the cardiac injury (infarct size: 60%), compared to the control. But in DM heart, physiological recovery was prominent in the initial phase of reperfusion but deteriorated towards the end of reperfusion, supported by less infarct size. In addition, elevated lipid peroxidation (70% in DCM-I/R vs Sham) and impaired antioxidant enzymes (% decline vs Sham: GSH - 56% (DM), 63% (DCM); Catalase - 58% (DM), 35% (DCM); GPx - 19% (DM), 27% (DCM) and GR - 28% (DCM)) was observed in myocardial tissue from both DM and DCM. Interestingly, upon reperfusion, only normal heart showed significant deterioration in the antioxidant defense system. Collectively these results demonstrated that I/R induced oxidative stress is minimal in DM and DCM rat heart, despite high infarct size and low cardiac performance. This may be due to the prior adaptive modification in the antioxidant system associated with disease pathology. PMID- 29462718 TI - Genetic diversity of the Plasmodium vivax phosphatidylinositol 3-kinase gene in two regions of the China-Myanmar border. AB - Artemisinin resistance in Plasmodium falciparum was associated with mutations in the propeller domain of the PfK13 gene and increased phosphatidylinositol-3' kinase (PfPI3K) activity. Assessment of the genetic diversity of the PfK13 ortholog PvK12 in Plasmodium vivax field samples from the same hotspots of P. falciparum artemisinin resistance revealed a limited genetic diversity of PvK12. Following the same logic, we analyzed genetic variations of the PvPI3K gene in 188 P. vivax field isolates from two geographic locations along the China-Myanmar border. Overall, high genetic diversity of PvPI3K was observed; parasites from Yunnan's Tengchong County had higher genetic diversity than those from Laiza Township, Kachin State, Myanmar. Almost all the neutrality tests applied detected statistically significant deviation from zero. The negative Tajima's D values in both populations implicated that PvPI3K gene might have experienced either a directional selection or an expansion in population size. There was low linkage disequilibrium between the PvPI3K mutations in both populations, suggesting the existence of large, almost panmictic, parasite populations that enabled effective recombination. This later result was confirmed by the detection of a minimum of five recombination events in each population with two major breakpoints. Multiple tests for selection confirmed a signature of purifying selection on PvPI3K. All the amino acid mutations were predicted to be neutral for the PI3K protein's function. These findings provide insights on the genetic diversity of P. vivax populations along the China-Myanmar border. PMID- 29462719 TI - Comparative genomics of Vibrio cholerae El Tor strains isolated at epidemic complications in Siberia and at the Far East. AB - The territory of Siberia and the Far East of Russia is classified as epidemically safe for cholera; however, in the 1970s and 1990s a number of infection importation cases and acute outbreaks associated with the cholera importation were reported. Here, we analyze genomes of four Vibrio cholerae El Tor strains isolated from humans during epidemic complications (imported cases, an outbreak) in the 1990s. The analyzed strains harbor the classical allele of the cholera toxin subunit B gene (ctxB1); thus, belong to genetically altered variants of the El Tor biotype. Analysis of the genomes revealed their high homology with the V. cholerae N16961 reference strain: 85-93 SNPs were identified in the core genome as compared to the reference. The determined features of SNPs in the CTX prophage made it possible to propose the presence of a new subtype - CTX-2a in two strains; the other two strains carried the prophage of CTX-3 type. Results of phylogenetic analysis based on SNP-typing demonstrated that two strains belonged to the second wave, and two - to the early third wave of cholera dissemination in the world. Phylogenetic reconstruction in combination with epidemiological data permitted to trace the origin of the strains and the way of their importation to the Russian Federation directly or through temporary cholera foci. PMID- 29462720 TI - Engineering Introns to Express RNA Guides for Cas9- and Cpf1-Mediated Multiplex Genome Editing. AB - The clustered regularly interspaced short palindromic repeat (CRISPR) system has emerged as the revolutionary platform for DNA targeting. This system uses a site specific RNA guide to direct a CRISPR effector (e.g., Cas9 and Cpf1) to a DNA target. Here, we elaborate a general strategy to simultaneously express multiple guide RNAs (gRNA) and CRISPR RNAs (crRNA) from introns of Cas9 and Cpf1. This method utilizes the endogenous tRNA processing system or crRNA processing activity of Cpf1 to cleave the spliced intron that contains tRNA-gRNA polycistron or crRNA-crRNA array. We demonstrated that the tRNA-gRNA intron is able to fuse with Cas9 as one gene. Such a hybrid gene could be expressed using one polymerase II promoter, and exhibited high efficiency and robustness in simultaneously targeting multiple sites. We also implemented this strategy in Cpf1-mediated genome editing using intronic tRNA-crRNA and crRNA-crRNA arrays. Interestingly, hybrid genes containing Cpf1 and intronic crRNA array exhibited remarkably increased efficiency compared with the conventional Cpf1 vectors. Taken together, this study presents a method to express CRISPR reagents from one hybrid gene to increase genome-editing efficiency and capacity. Owing to its simplicity and versatility, this method could be broadly used to develop sophisticated CRISPR tools in eukaryotes.

PMID- 29462722 TI - Relationships between Gene Structure and Genome Instability in Flowering Plants. AB - Flowering plant (angiosperm) genomes are exceptional in their variability with respect to genome size, ploidy, chromosome number, gene content, and gene arrangement. Gene movement, although observed in some of the earliest plant genome comparisons, has been relatively underinvestigated. We present herein a description of several interesting properties of plant gene and genome structure that are pertinent to the successful movement of a gene to a new location. These considerations lead us to propose a model that can explain the frequent success of plant gene mobility, namely that Small Insulated Genes Move Around (SIGMAR). The SIGMAR model is then compared with known processes for gene mobilization, and predictions of the SIGMAR model are formulated to encourage future experimentation. The overall results indicate that the frequent gene movement in angiosperm genomes is partly an outcome of the unusual properties of angiosperm genes, especially their small size and insulation from epigenetic silencing. PMID- 29462723 TI - Comparison of two integration methods for dynamic causal modeling of electrophysiological data. AB - Dynamic causal modeling (DCM) is a methodological approach to study effective connectivity among brain regions. Based on a set of observations and a biophysical model of brain interactions, DCM uses a Bayesian framework to estimate the posterior distribution of the free parameters of the model (e.g. modulation of connectivity) and infer architectural properties of the most plausible model (i.e. model selection). When modeling electrophysiological event related responses, the estimation of the model relies on the integration of the system of delay differential equations (DDEs) that describe the dynamics of the system. In this technical note, we compared two numerical schemes for the integration of DDEs. The first, and standard, scheme approximates the DDEs (more precisely, the state of the system, with respect to conduction delays among brain regions) using ordinary differential equations (ODEs) and solves it with a fixed step size. The second scheme uses a dedicated DDEs solver with adaptive step sizes to control error, making it theoretically more accurate. To highlight the effects of the approximation used by the first integration scheme in regard to parameter estimation and Bayesian model selection, we performed simulations of local field potentials using first, a simple model comprising 2 regions and second, a more complex model comprising 6 regions. In these simulations, the second integration scheme served as the standard to which the first one was compared. Then, the performances of the two integration schemes were directly compared by fitting a public mismatch negativity EEG dataset with different models. The simulations revealed that the use of the standard DCM integration scheme was acceptable for Bayesian model selection but underestimated the connectivity parameters and did not allow an accurate estimation of conduction delays. Fitting to empirical data showed that the models systematically obtained an increased accuracy when using the second integration scheme. We conclude that inference on connectivity strength and delay based on DCM for EEG/MEG requires an accurate integration scheme. PMID- 29462725 TI - Superimposition of maximal stress and necrosis areas at the top of the femoral head in hip aseptic osteonecrosis. AB - INTRODUCTION: Recent reports described possible mechanical factors in the development and aggravation of osteonecrosis of the femoral head (OFH), but these have yet to be confirmed on dedicated mechanical study. We therefore developed a 3D finite element model based on in-vivo data from patients with incipient OFH, with a view to determining whether the necrosis area was superimposed on the maximal stress area on the femoral head. HYPOTHESIS: The location of the necrosis area is determined by stress on the femoral head. MATERIAL AND METHOD: All patients from the rheumatology department with early stage OFH in our center were investigated. Analysis of CT scans showed stress distribution on the head by 3D finite elements models, enabling determination of necrosis volume within the maximal stress area and of the percentage intersection of necrosis within the stress area (%I n/s: necrosis volume in stress area divided by total stress area volume and multiplied by 100) and of stress within the necrosis area (%I s/n: stress volume in necrosis area divided by total necrosis area volume and multiplied by 100). RESULTS: Nineteen of the 161 patients assessed retrospectively for the period between 2006 and 2015 had incipient unilateral OFH, 10 of whom (4 right, 6 left) had CT scans of sufficient quality for inclusion. Mean age was 52 years (range, 37-81 years). Mean maximal stress was 1.63MPa, mean maximal exported stress volume was 2,236.9 mm3 and mean necrosis volume 6,291.1 mm3. Mean %I n/s was 83% and mean %I s/n 35%, with no significant differences according to gender, age, side or stress volume. There was a strong inverse correlation between necrosis volume and %I s/n (R2=-0.92) and a strong direct correlation between exported stress volume and %I s/n (R2=0.55). %I s/n was greater in small necrosis (<7,000mm3). CONCLUSION: OFH seems to develop within the maximal stress area on the femoral head. The present results need confirmation by larger-scale studies. We consider it essential to take account of these mechanical parameters to reduce failure rates in conservative treatment of OFH. LEVEL OF EVIDENCE: IV. CASE SERIES: PMID- 29462726 TI - Clinically-diagnosed Mediterranean Spotted Fever in Malta. AB - BACKGROUND: Mediterranean Spotted Fever (MSF) is a tick-borne zoonosis caused by Rickettsia conorii which is endemic in Malta, an island in the South Mediterranean that is a popular tourist destination. Diagnosis is frequently based on clinical manifestations as laboratory results are often limited to a retrospective diagnosis. We describe the clinical presentation, diagnosis and treatment of children <16 years who presented with MSF from 2011 to 2016. METHOD: The demographics, clinical findings, laboratory results, management and outcome of all children hospitalised with suspected MSF based on the presence of fever and an eschar, were retrieved from their case notes. RESULTS: Over the five-year study period six children, aged between 17 months and 15 years, were diagnosed with MSF. All children had contact with ticks and the majority presented in summer. Laboratory results were non-specific and included elevated inflammatory markers, lymphocytosis/lymphopenia and hyponatraemia. Serological and molecular techniques were used for diagnosis. Response to clarithromycin or doxycycline was immediate. CONCLUSION: MSF should be included in the differential diagnosis of fever, rash and an eschar in children who travel to Malta. Despite advances in molecular diagnostics, clinical diagnosis remains important in the management of children with suspected MSF.

AB - The functional significance of resting state networks and their abnormal manifestations in psychiatric disorders are firmly established, as is the importance of the cortical rhythms in mediating these networks. Resting state networks are known to undergo substantial reorganization from childhood to adulthood, but whether distinct cortical rhythms, which are generated by separable neural mechanisms and are often manifested abnormally in psychiatric conditions, mediate maturation differentially, remains unknown. Using magnetoencephalography (MEG) to map frequency band specific maturation of resting state networks from age 7 to 29 in 162 participants (31 independent), we found significant changes with age in networks mediated by the beta (13-30 Hz) and gamma (31-80 Hz) bands. More specifically, gamma band mediated networks followed an expected asymptotic trajectory, but beta band mediated networks followed a linear trajectory. Network integration increased with age in gamma band mediated networks, while local segregation increased with age in beta band mediated networks. Spatially, the hubs that changed in importance with age in the beta band mediated networks had relatively little overlap with those that showed the greatest changes in the gamma band mediated networks. These findings are relevant for our understanding of the neural mechanisms of cortical maturation, in both typical and atypical development. PMID- 29462727 TI - Children's understanding of yesterday and tomorrow. AB - A picture-sentence matching task was used to investigate children's understanding of yesterday and tomorrow. In Experiment 1, 3- to 5-year-olds viewed two pictures of an object with a visible change of state (e.g., a carved pumpkin and an intact pumpkin) while listening to sentences referring to past or future actions ("I carved the pumpkin yesterday" or "I'm gonna carve the pumpkin tomorrow") and selected the matching picture. Children performed better with past tense sentences than with future tense sentences, and including tomorrow in future tense sentences increased accuracy. In the next two experiments, 4- and 5-year olds (Experiment 2) and adults (Experiment 3) completed the same task but with sentences containing conflicting temporal information ("I carved the pumpkin tomorrow"). Children tended to select pictures depicting the outcome of actions regardless of tense or temporal adverb, whereas adults' judgments were based on temporal adverbs. In Experiment 4, 3- to 5-year-olds completed tasks requiring either forward or backward temporal reasoning about sentences referring to before, after, yesterday, today, and tomorrow. Across sentence types, forward temporal reasoning was easier for children than backward temporal reasoning. Altogether, results indicated that children understand yesterday better than tomorrow due to the increased cognitive demands involved in reasoning about future events. PMID- 29462728 TI - Treatment of lumbar discitis using silicon nitride spinal spacers: A case series and literature review. AB - INTRODUCTION: Septic infection of a lumbar intervertebral disc is a serious disorder which is often difficult to diagnose and appropriately treat because of the rarity of the disease, the varied presentation of symptoms, and the frequency of low-back pain within the overall population. Its etiology can be pyogenic, granulomatous, fungal, or parasitic; its incidence is rising due to increased patient susceptibility and improved diagnostic tools. Conservative treatments involve antibiotics, physical therapy, and/or immobilization. More aggressive management requires discectomy, debridement, and spinal fusion in combination with local and systemic antibiotic administration. PRESENTATION OF CASES: Presented here are two case studies of lumbar pyogenic discitis associated with Escherichia coli and Candida albicans infections. Both required single-level anterior discectomy followed by spinal fusion using an antimicrobial silicon nitride (Si3N4) spacer for stabilization without instrumentation. Localized antibiotics were used for only one of the patients. Follow-up CT and MRI scans showed that the infections had been resolved with no recurrence of symptoms. DISCUSSION: Si3N4 is a relatively new spinal spacer material. It was utilized in these two cases because it reportedly provides a local environment which promotes rapid arthrodesis while resisting bacterial adhesion and biofilm formation. It is also highly compatible with X-ray, MRI, and CT imaging modalities. These properties were particularly attractive for these two cases given the patients' histories, presentation of symptoms, and the decision to forego instrumentation. CONCLUSION: The use of Si3N4 as an antimicrobial spacer may lead to improved outcomes for patients with pyogenic discitis of the lumbar spine. PMID- 29462729 TI - The Influence of Artificial Cervical Disc Prosthesis Height on the Cervical Biomechanics: A Finite Element Study. AB - OBJECTIVE: Artificial cervical disc replacement is expected to maintain normal cervical biomechanics. At present, the effect of the Prestige LP prosthesis height on cervical biomechanics has not been thoroughly studied. This finite element study of the cervical biomechanics aims to predict how the parameters, like range of motion (ROM), adjacent intradiscal pressure, facet joint force, and bone-implant interface stress, are affected by different heights of Prestige LP prostheses. METHODS: The finite element model of intact cervical spine (C3-C7) was obtained from our previous study, and the model was altered to implant Prestige LP prostheses at the C5-C6 level. The effects of the height of 5, 6, and 7 mm prosthesis replacement on ROM, adjacent intradiscal pressure, facet joint force, as well as the distribution of bone-implant interface stress were examined. RESULTS: ROM, adjacent intradiscal pressure, and facet joint force increased with the prosthesis height, whereas ROM and facet joint force decreased at C5-C6. The maximal stress on the inferior surface of the prostheses was greater than that on the superior surface, and the stresses increased with the prosthesis height. The biomechanical changes were slightly affected by the height of 5 and 6 mm prostheses, but were strongly affected by the 7-mm prosthesis. CONCLUSIONS: An appropriate height of the Prestige LP prosthesis can preserve normal ROM, adjacent intradiscal pressure, and facet joint force. Prostheses with a height of >=2 mm than normal can lead to marked changes in the cervical biomechanics and bone-implant interface stress. PMID- 29462730 TI - Biomechanical Stability Afforded by Unilateral Versus Bilateral Pedicle Screw Fixation with and without Interbody Support Using Lateral Lumbar Interbody Fusion. AB - OBJECTIVE: To determine the stability of fusion constructs with unilateral pedicle screw (UPS) or bilateral pedicle screw (BPS) fixation with and without an interbody implant using the lateral lumbar interbody (LLIF) approach. METHODS: Standard nondestructive flexibility tests were performed on 13 cadaveric lumbar specimens to assess spinal stability of intact specimens and 5 configurations of posterior and interbody instrumentation. Spinal stability was determined as mean range of motion in flexion-extension, lateral bending, and axial rotation. Nonpaired comparisons were made for these 6 conditions: 1) intact; 2) unilateral interbody via the LLIF approach (LLIF construct); 3) unilateral interbody + unilateral pedicle screws (UPS) via the LLIF approach (LLIF + UPS); 4) unilateral interbody + bilateral pedicle screws (BPS) using the LLIF approach (LLIF+BPS); 5) UPS alone; and 6) BPS alone. RESULTS: UPS and BPS, with and without interbody support, significantly reduced range of motion during the majority of directions of loading. BPS alone provided greater stability than UPS alone and LLIF alone in all directions of motion except axial rotation. With interbody support, there was no significant difference in stability between BPS and UPS across all movement directions. CONCLUSIONS: These biomechanical results suggest that fixation in the lumbar spine with an interbody support using an LLIF approach with UPS is a promising alternative to BPS. Although BPS provides greater immediate stability compared with UPS, in the presence of a lateral interbody implant, UPS and BPS provide equivalent stability. In addition, LLIF does not appear to contribute significantly to immediate stability when BPS is used. PMID- 29462731 TI - Another Endovascular Therapy Strategy for Acute Tandem Occlusion: Protect-Expand Aspiration-Revascularization-Stent (PEARS) Technique. AB - OBJECTIVE: Initial stenotic occlusion of the internal carotid artery with intracranial artery occlusion in acute ischemic stroke is associated with high morbidity and can benefit from endovascular therapy. However, the optimal endovascular strategy is unclear. This study aimed to evaluate the feasibility of the "half" anterograde approach and clinical outcome of treated patients. Revascularization validity of the 2 "half" anterograde approach with (Protect Expand-Aspiration-Revascularization-Stent [PEARS] technique) or without (plain technique) using an embolic prevention device and aspiration was also compared. METHODS: Data on initial stenotic occlusion of the internal carotid artery with intracranial artery occlusion in our prospective stroke registry database between January 2015 and February 2017 were collected. Clinical and angiographic data were retrospectively analyzed. Clinical outcome was evaluated at 3 months, defined as a modified Rankin scale <=2 as a good clinical outcome. RESULTS: Overall, 26 patients with tandem occlusion were included; 96.3% of patients had successful recanalization. The rate of a good clinical outcome was 61.8%, symptomatic parenchymal hemorrhage was 7.7%, and mortality was 15.4%. The PEARS technique took less time (56 +/- 14 vs. 97 +/- 31 minutes; P = 0.002) and had less embolic events (0 vs. 30.8%; P = 0.012) compared with the plain technique. Use of the PEARS technique was an independent predictor for shortening revascularization time (beta = -0.651, P = 0.001). CONCLUSIONS: The half anterograde approach technique is feasible and safe for treating tandem occlusion. Furthermore, the PEARS technique is associated with a shorter reperfusion time and less embolic events than the plain technique, and should be recommended in tandem occlusion. PMID- 29462732 TI - Characteristics and Endovascular Management of the Posterior Cerebral Artery Anterior Temporal Branch Aneurysms. AB - PURPOSE: To investigate characteristics of the posterior cerebral artery anterior temporal branch aneurysm and the safety and efficacy of endovascular management. MATERIALS AND METHODS: A total of 6 patients with anterior temporal branch aneurysms were enrolled. All 6 patients had concurrent occlusion of the ipsilateral anterior circulating arteries. The aneurysms ranged from 2.5 to 5.0 mm. All patients were treated and followed up. RESULTS: Four unruptured aneurysms were treated with coil embolization of the aneurysm sac only, with the parent artery maintained in 2 patients, slow flow in the parent artery in one and thrombosis at the aneurysm neck leading to parent artery occlusion in the last one. One patient with subarachnoid hemorrhage was treated with coil embolization of both the aneurysm and the parent artery, and the last patient with subarachnoid hemorrhage was treated with the Glubran 2 glue to embolize both the aneurysm and the parent artery. One patient with subarachnoid hemorrhage died of lung complication after embolization. Followed up for 3 months to 1 year, the 4 patients with unruptured aneurysms had no symptoms, including 1 patient with slow flow in the anterior temporal artery and 1 patient with thrombosis and parent artery occlusion. The remaining patient with parent artery occlusion had a good recovery. CONCLUSIONS: The anterior temporal artery aneurysm is a special subtype of aneurysm and can be readily misdiagnosed as on the posterior cerebral artery trunk or the superior cerebellar artery. Endovascular management has a greater success rate, good effect, and fewer complications but with greater difficulties. PMID- 29462733 TI - The Effects of Intermittent Whole-Body Hypoxic Preconditioning on Patients with Carotid Artery Stenosis. AB - OBJECTIVE: To study the effects of intermittent whole-body hypoxic preconditioning on patients with carotid artery stenosis. METHODS: Fifty patients with carotid artery stenosis were selected and randomly divided into a hypoxic intervention group (HIG) and a control group (CG). Both groups were treated with a hypoxic respiration device for 7 days (HIG: 18% oxygen, CG: 21% oxygen). Venous blood samples were taken preoperatively and postoperatively. The subjects' vital signs were recorded during and after the intervention. After the completion of the trial, the concentrations of hemoglobin, hypoxia inducible factor-1alpha, erythropoietin, vascular endothelial growth factor, neuron-specific enolase, S100beta protein, brain-derived neurotrophic factor, serum aspartate transaminase, serum alanine aminotransferase, serum creatinine, and blood urea nitrogen were measured in the previously selected blood samples. RESULTS: During the intervention, the vital signs of the HIG were significantly different from those of the CG (P < 0.05). In the HIG, postoperative concentrations of hemoglobin, erythropoietin, hypoxia inducible factor-1alpha, and vascular endothelial growth factor were significantly more than the preoperative values (P < 0.05). In the CG, postoperative concentrations of neuron-specific enolase and S100beta protein were more than the preoperative values (P < 0.05). The concentrations of brain-derived neurotrophic factor, serum aspartate transaminase, serum alanine aminotransferase, serum creatinine, and blood urea nitrogen showed no significant differences between their preoperative and postoperative values in either the HIG or the CG (P > 0.05). CONCLUSIONS: Intermittent hypoxic preconditioning can change the vital signs and hematologic indexes of patients with carotid artery stenosis without causing new postoperative complications or organ damage. PMID- 29462734 TI - Divergent Bilateral Posterior Lumbar Interbody Fusion with Cortical Screw Fixation: Description of New Trajectory for Interbody Technique from Midline Exposure. AB - BACKGROUND: A major drawback to use of cortical bone trajectory pedicle screws (CBTPSs) with traditional posterior lumbar interbody fusion (PLIF) and transforaminal lumbar interbody fusion grafts is that traditional graft insertion trajectories require wider posterior exposure. This wider exposure, beyond the limits otherwise required for CBTPS placement, negates a primary benefit of CBTPS fixation. The aim of this study was to define an alternative surgical technique for interbody graft placement that, when used in conjunction with CBTPS fixation, permits both minimal soft tissue dissection and optimal graft placement. METHODS: A team of neurosurgeons specializing in treatment of spinal pathologies developed a surgical technique for insertion of bilateral PLIF grafts that complements the principles of CBTPS fixation. This technique is illustrated in a patient undergoing lumbosacral decompression, CBTPS fixation, and 3-column arthrodesis. RESULTS: The described technique uses a divergent trajectory of bilateral PLIF grafts rather than the traditional parallel or convergent trajectories. CONCLUSIONS: By aiming medially to laterally with the interbody graft, one recapitulates many advantages of CBTPSs, including avoidance of wide tissue dissection, greater intergraft volume available for bone grafting, and greater graft coverage of the hypophyseal ring. The prospective collection of outcome data for patients who undergo lumbosacral fusion using the divergent PLIF technique is ongoing. PMID- 29462736 TI - Use of a Pediatric Craniotome Drill for Cervical and Thoracic Spine Decompression: Safety and Efficacy. AB - BACKGROUND: Laminectomy, using a high-speed drill with an unprotected cutting drill bit, can be rapid and effective, but it has been associated with known complications. Another technique uses a pediatric craniotome drill with the footplate attachment. At present, there are no studies comparing clinical outcomes between these 2 stated decompressive techniques. METHODS: A retrospective review was conducted at a single institution. Two cohorts of patients were considered based on the technical method of laminectomy for decompression. One group had decompression with utilization of a high-speed drill, whereas the other group had decompression with a pediatric craniotome drill with a footplate attachment. The outcomes from each group were compared based on the length of operation, estimated blood loss, and associated complications. RESULTS: A total of 91 patients were included in the final analysis. Forty-five of the patients underwent laminectomy using a footplate and 46, using a high-speed drill. The footplate group was associated with significantly shorter operative time (159 vs. 205 minutes; P = 0.008). In addition, the footplate technique demonstrated less estimated blood loss (254 vs. 349 mL), and less incidence of durotomies (2.2% vs. 10.9%); however, neither of these 2 outcomes achieved statistical significance. CONCLUSIONS: Despite being an older technique, there was a shorter operative time in the footplate group without increased blood loss or incidence of durotomy. Although comparable results are operator dependent, this technique is a safe alternative for performing cervical and thoracic laminectomies. PMID- 29462735 TI - Anatomical Variations of Brain Venous Sinuses in Patients with Arteriovenous Malformations: Incidental Finding or Causative Factor? AB - OBJECTIVE: Acquired anomalies of the dural venous sinuses (DVS) have been correlated extensively with the development of dural arteriovenous fistulas (DAVFs). Despite the known similarities of DAVFs' pathogenesis with that of arteriovenous malformations (AVMs), the relationship of venous sinuses anomalies with AVMs scarcely has been studied. We aimed to investigate whether patients with AVM show a greater prevalence of congenital DVS anomalies. We hypothesized that these congenital anomalies trigger AVM development during early childhood just as acquired DVS anomalies trigger DAVFs formation during adulthood. METHODS: Angiographic anomalies of the brain venous sinuses were studied in a cohort of 45 consecutive patients with AVM and compared with the angiographic; venous sinus anomalies of a control group formed by a second consecutive; series of 45 patients with subarachnoid hemorrhage. RESULTS: Congenital anomalies of any DVS were more frequent in patients with AVM than in the control group (49.8% vs. 22.2%; P = 0.015). Congenital abnormalities of the superior sagittal sinus not only were more frequent in patients with AVM (27% vs. 6.7%; P = 0.021) but seemed also related to the AVM location: in 5 of the 6 AVM cases with unilateral superior sagittal sinus aplasia, the AVM was ipsilateral to the venous anomaly. CONCLUSIONS: Patients with AVM have a greater likelihood of congenital anomalies of any DVS. These anomalies seem to be related also to the AVM location. These findings suggest that congenital anomalies of DVS may be related to the development of AVMs. PMID- 29462738 TI - Detecting dysplasia using white light endoscopy or chromoendoscopy in ulcerative colitis patients without primary sclerosing cholangitis: A systematic review and meta-analysis. AB - BACKGROUND: Endoscopic examinations are a vital diagnostic tool for dysplasia. Establishing the precision of different modes of examination is essential due to the disparate pick-up rates of dysplasia. OBJECTIVE: The aim of this article was to establish the pick-up rates of dysplastic or cancerous lesions using white light endoscopy (WLE) and random/targeted biopsies, or chromoendoscopy (CE), in patients with ulcerative colitis (UC) without primary sclerosing (PSC) or Crohn's disease (CD). DATA SOURCES: A systematic review to identify all studies up to November 2017, without language restriction, was conducted from PubMed, the Cochrane Controlled Trials Register (1960-2017), MEDLINE, CINAHL and EMBASE (1981 2017). MeSH and text word terms used included "ulcerative colitis", "dysplasia", "random biopsy", "targeted biopsy", "colonoscopy", "white light", and "chromoendoscopy". Further searches were performed using the bibliographies of these articles. STUDY SELECTION: All studies reporting on colonoscopy detection rates of dysplasia and cancers in UC without involvement of PSC or CD were included. There was no age restriction to include patients. DATA EXTRACTION: Outcome data were extracted by 2 authors independently using outcome measures defined a priori. Quality assessment was performed using the Newcastle-Ottawa scales. DATA SYNTHESIS: Data were extracted and analysed according to meta analytical techniques using comprehensive meta-analysis. The pooled overall pick up rate of dysplastic/cancerous lesions on WLE random biopsies was 5.6% [Event rate 0.06 (0.01, 0.23), df = 4, I2 = 94%]. Using a combined random and targeted approach with WLE the incidence was 5.1% [Event rate 0.05 (0.03, 0.09), df = 4, I2 = 96%]. One study reported on CE and found a 7% pick-up rate for dysplastic lesions. CONCLUSIONS: Endoscopic examination of UC patients without PSC identifies dysplastic or cancerous lesions in 5-7% of cases. WLE and random biopsies may pick-up a similar number of lesions to targeted biopsies, however the number of biopsies may need to be greater to achieve this equivalence. CE has a slightly higher pick-up rate. Further comparative studies are required to strengthen the body of evidence. PMID- 29462737 TI - Pancreas-preserving management of grade-C pancreatic fistula and a novel bridging technique for repeat pancreaticojejunostomy: An observational study. AB - PURPOSE: Optimal surgical strategy for grade-C postoperative pancreatic fistula (POPF) after pancreaticoduodenectomy (PD) is not justified. External wirsungostomy is feasible. However, the subsequent repeat pancreaticojejunostomy (PJ) is challenging. This study aims to introduce our experience of external wirsungostomy for grade-C POPF and a novel technique to do the repeat PJ (re-PJ). MATERIALS AND METHODS: From January 1, 2012 to December 31, 2016, all consecutive patients who underwent pancreaticoduodenectomy (PD) with PJ were identified. The clinical data were retrospectively collected and analyzed. RESULTS: Out of 325 patients, 11 patients (3.38%) underwent salvage re-laparotomy for grade-C POPF. External wirsungostomy was performed in 10 patients (3.08%). Four patients died of severe complications within 90 days postoperatively or tumor progression before the scheduled re-PJ was performed. Three patients got their external pancreatic drainage tube pulled out accidentally without causing severe consequences. Three patients underwent planned re-PJ after external wirsungostomy, including one with duct-to-mucosa PJ and two with the novel bridging technique. The operative times of the two patients undergoing the novel bridging technique were 120 min, 135 min, respectively, and the length of post operative hospital stay (LPHS) were 7 d, 5 d, respectively. The operative time and the LPHS of whom underwent duct-to-mucosa PJ were 315 min, 24 d, respectively. There was no major post-operative complication. CONCLUSION: External wirsungostomy may be a safe way to preserve the pancreas remnant in grade-C POPF patients. The novel bridging technique may be a simpler alternative to traditional PJ. PMID- 29462739 TI - Pre-surgery beliefs about pain and surgery as predictors of acute and chronic post-surgical pain: A prospective cohort study. AB - BACKGROUND: Chronic pain post-surgical pain (CPSP) is common and has far-reaching negative consequences for patients, yet relatively few studies have evaluated the impact of both deficit- and resource-based beliefs about pain and surgery on subjective intensities of acute and chronic post-surgical pain. To address this issue a prospective cohort study was performed. METHOD: 259 consecutive surgery patients from general surgery, gynecology, and thoracic departments completed a self-report battery of demographics, pain experiences, and psychological factors 24 h before surgery (T1) and provided follow-up pain intensity ratings 48 h-72 h after surgery (T2), and at a 4-month follow-up (T3). RESULTS: In the hierarchical regression model for acute post-operative pain intensity, pre-surgery pain self efficacy beliefs made a significant unique contribution independent of all other pre-surgery and surgery-related factors (i.e., age, presence of pre-surgical pain, type of anesthesia, surgery duration). In the prediction model for intensity of chronic post-surgical pain, beliefs about long-term effects of surgery had a unique impact after controlling other significant pre-surgery and surgery influences (gender, education, surgery time). CONCLUSION: Results underscored the potential utility of considering specific pre-surgery pain- and surgery-related beliefs as factors that predict patient experiences of acute and chronic post-operative pain. PMID- 29462740 TI - Listening to the voice of children with developmental speech and language disorders using narrative inquiry: Methodological considerations. AB - There are policy and theoretical drivers for listening directly to children's perspectives. These perspectives can provide insights to children's experiences of their daily lives and ways in which they construct their multiple identities. Qualitative methodology is a useful research paradigm with regard to exploring children's experiences. However, listening to the perspectives of children with speech and language disorders is a relatively new field of research. Therefore, it is important that researchers share their experiences of using methods and reflect on the strengths and limitations of these methods. The authors have used narrative inquiry with children with speech and language disorders to explore ways in which these children make sense of their experiences and construct their identities. In this paper, the authors reflect on methodological considerations when using narrative inquiry with children with speech and language disorders. They critically discuss three methodological considerations: narrative inquiry as a methodological choice, methods for data generation, limitations, and rigour. PMID- 29462741 TI - Synchrotron-based X-ray fluorescence study of gold nanorods and skin elements distribution into excised human skin layers. AB - Understanding the distribution of nanoparticles in skin layers is fundamentally important and essential for developing nanoparticle-based dermal drug delivery systems. In the present study, we provide insights into the distribution of gold nanorods (GNRs) functionalized with hydrophobic or hydrophilic ligands in human skin layers using synchrotron X-ray fluorescence (SR-XRF) spectroscopy, confocal microscopy, and transmission electron microscopy. The results confirmed the important role that the surface chemistry of GNRs plays in their penetration into the skin; the GNRs coated with polyethylene glycol were distributed into the skin layers to a greater extent than the GNRs coated with hydrophobic polystyrene thiol. In addition, SR-XRF analysis revealed that the spatial distribution of endogenous elements (phosphorus and sulfur) in skin layers demonstrated a significant "anti-correlation" relationship with that of GNRs. These results suggest possible association (via adsorption) between the GNRs and these two elements localized in skin, which can be valuable for understanding the penetration mechanism of gold nanoparticles into the skin. PMID- 29462743 TI - Utility of soluble lectin-like oxidized low-density lipoprotein receptor-1 (sLOX 1) in the postmortem diagnosis of ischemic heart disease. AB - PURPOSE: Ischemic heart disease (IHD) is a major cause of death in developed countries. Postmortem IHD diagnosis using biochemical markers is difficult because of the postmortem changes. In the present study, we investigated the utility of soluble lectin-like low-density lipoprotein receptor-1 (sLOX-1) in body fluids obtained from forensic autopsy cases. METHODS: We measured pericardial fluid, urine, and serum sLOX-1 levels; these samples were obtained from medicolegal autopsy cases (n = 149, postmortem interval <72 h), and the utility of these biomarkers postmortem acute IHD diagnosis was evaluated. RESULTS: The pericardial fluid and urine of patients with acute IHD had higher sLOX-1 levels (p < .05) compared to the controls. No significant differences were found between the sLOX-1 level and the degree of coronary atherosclerosis, body mass index, and postmortem interval. CONCLUSION: sLOX-1 levels in pericardial fluid and urine samples obtained postmortem are useful markers of acute IHD. PMID- 29462742 TI - Refractory status epilepticus: Impact of baseline comorbidity and usefulness of STESS and EMSE scoring systems in predicting mortality and functional outcome. AB - PURPOSE: Little has been published on the prognostic value of the Status Epilepticus Severity Score (STESS) or the Epidemiology-based Mortality score in Status Epilepticus (EMSE) in refractory status epilepticus (RSE). We sought to analyze the prognostic value of STESS and EMSE and the impact of baseline comorbidities in mortality and functional outcome in RSE. METHODS: We designed an observational retrospective study of patients diagnosed with RSE between August 2013 and September 2017. For each patient, we analyzed prospectively recorded demographic, clinical, comorbidity, electroencephalographic, treatment, and hospital stay-related data and calculated STESS and EMSE. All variables were compared statistically between patients with good and poor functional outcome at discharge and between patients who died in hospital and those who were alive at discharge. RESULTS: Fourty-nine patients had RSE; 35.4% died in hospital and 88% showed functional decline at discharge. Mortality was associated with baseline chronic kidney disease (CKD) (OR 19.25, p = 0.006), baseline modified Rankin scale score (mRS) (OR 3.38, p = 0.005), non-convulsive status epilepticus (NCSE) with coma (OR 11.9, p = 0.04), STESS (OR 2, p = 0.04), and EMSE (OR 1.3, p = 0.02). Functional outcome was associated with baseline mRS (OR 13.9, p = 0.02), and EMSE (OR 1.3, p = 0.02). The optimal cutoff scores for predicting mortality were 4 for STESS and 60 for EMSE. EMSE predicted functional outcome with an optimal cutoff of 40. CONCLUSIONS: CKD, NCSE with coma and STESS were associated with mortality. mRS and EMSE were associated with mortality and functional outcome. EMSE was useful for predicting functional outcome, while EMSE and STESS were useful for predicting in-hospital mortality. PMID- 29462744 TI - Eye injuries from electrical weapon probes: Incidents, prevalence, and legal implications. AB - PURPOSE: While generally reducing morbidity and mortality, electrical weapons have risks associated with their usage, including burn injuries and trauma associated with uncontrolled fall impacts. However, the prevalence of significant eye injury has not been investigated. METHODS: We searched for incidents of penetrating eye injury from TASER(r) conducted electrical weapon (CEW) probes via open source media, litigation filings, and a survey of CEW law-enforcement master instructors. RESULTS: We report 20 previously-unpublished cases of penetrating eye injury from electrical weapon probes in law-enforcement field uses. Together with the 8 previously published cases, there are a total of 28 cases out of 3.44 million field uses, giving a demonstrated CEW field-use risk of penetrating eye injury of approximately 1:123 000. Confidence limits [85 000, 178 000] by Wilson score interval. There have been 18 cases of total unilateral blindness or enucleation. We also present legal decisions on this topic. CONCLUSIONS: The use of electrical weapons presents a rare but real risk of total or partial unilateral blindness from electrical weapon probes. Catastrophic eye injuries appear to be the dominant non-fatal complication of electronic control. PMID- 29462746 TI - Developmental changes in infants' and mothers' pathways to achieving joint attention episodes. AB - Combining the joint attention approaches of Mundy and colleagues' (2007) experimental coding of infants' specific initiating and responding acts and of Bakeman and Adamson's (1986) descriptions of both infants' and mothers' behaviors during joint engagement, this study examined 29 infants' and mothers' initiatives and responses leading to success in achieving joint attention (JA) episodes during naturalistic interactions when infants were 13 and 17 months old. Analyses revealed developmental changes in initiative frequencies and in the origins of JA episodes. At 13 months, although infants' less sophisticated object-only initiatives (IObj) were most frequent, JA episodes most often originated in maternal combined initiatives (IJA), which focused on both object and partner. By 17 months, however, infants' combined initiatives were most frequent and led to more JA episodes than any other initiative type. Infants with more combined initiatives achieved more JA episodes at both ages and greater 17-month vocabularies. PMID- 29462745 TI - Physiological and molecular mechanism of defense in cotton against Verticillium dahliae. AB - Cotton, a natural fiber producing crop of huge importance for textile industry, has been reckoned as the backbone in the economy of many developing countries. Verticillium wilt caused by Verticillium dahliae reflected as the most devastating disease of cotton crop in several parts of the world. Average losses due to attack of this disease are tremendous every year. There is urgent need to develop strategies for effective control of this disease. In the last decade, progress has been made to understand the interaction between cotton-V. dahliae and several growth and pathogenicity related genes were identified. Still, most of the molecular components and mechanisms of cotton defense against Verticillium wilt are poorly understood. However, from existing knowledge, it is perceived that cotton defense mechanism primarily depends on the pre-formed defense structures including thick cuticle, synthesis of phenolic compounds and delaying or hindering the expansion of the invader through advanced measures such as reinforcement of cell wall structure, accumulation of reactive oxygen species (ROS), release of phytoalexins, the hypersensitive response and the development of broad spectrum resistance named as, systemic acquired resistance (SAR). Investigation of these defense tactics provide valuable information about the improvement of cotton breeding strategies for the development of durable, cost effective, and broad spectrum resistant varieties. Consequently, this management approach will help to reduce the use of fungicides and also minimize other environmental hazards. In the present paper, we summarized the V. dahliae virulence mechanism and comprehensively discussed the cotton molecular mechanisms of defense such as physiological, biochemical responses with the addition of signaling pathways that are implicated towards attaining resistance against Verticillium wilt. PMID- 29462747 TI - Involvement of a newly identified atypical type II crustin (SpCrus5) in the antibacterial immunity of mud crab Scylla paramamosain. AB - Crustins, the main AMP family in Crustacea, are generated as isoforms in many species and implicated in innate immune responses, but their detailed molecular mechanisms on susceptible bacteria remain largely unclear. Type II and type I crustins are distinguished by glycine-rich region (GRR), which is a major marker motif, and some type II crustins exhibit stronger antibacterial activities than their GRR deletion mutants. In the present study, a novel crustin, namely, SpCrus5, was functionally characterized from a commercially valuable crab Scylla paramamosain. SpCrus5 contained a typical cysteine-rich domain at the N-terminus, a conserved WAP domain in the center, and a special GRR at the C-terminus, which is located in a site that differs from that of GRRs in typical type II crustins found between signal peptides and cysteine-rich domains. SpCrus5 shared high similarities with most type II crustins, and it was more closely related to type II crustins than to other retrieved crustins. SpCrus5 was predominantly expressed in gills and remarkably upregulated after the crabs were challenged with Vibrio parahemolyticus or Staphylococcus aureus, suggesting that SpCrus5 might participate in antibacterial immune responses. To further elucidate how this C terminal GRR affects the function of SpCrus5, we harvested a GRR deletion mutant (SpCrus5-DeltaGRR) by deleting the GRR. Liquid growth inhibition assays demonstrated that the antimicrobial activity of SpCrus5 was stronger than that of SpCrus5-DeltaGRR, and the antibacterial spectrum of the former toward Gram negative bacteria was broader than that of the latter. Binding assays revealed that the microorganism-binding ability and polysaccharide-binding activity of SpCrus5 were stronger than those of SpCrus5-DeltaGRR. SpCrus5 or SpCrus5-DeltaGRR agglutinated all tested Gram-positive bacteria. Therefore, the antibacterial activities of SpCrus5 were stronger and broader than those of SpCrus5-DeltaGRR, and the binding ability and agglutination activity might contribute to the antimicrobial activity of SpCrus5. These results revealed that the C-terminal GRR was necessary to produce an efficient antibacterial activity of SpCrus5. SpCrus5 was highly identical with most type II crustins and it functioned as many type II crustins did, indicating that SpCrus5 was more likely an atypical type II crustin than a type I crustin. This study revealed that SpCrus5 participated as an essential antimicrobial effector in immune responses and provided new insights into the underlying mechanisms of the sequence and function diversity of crustins.

AB - Improving fish defense through the preventive administration of immunostimulants has an important role in controlling the outbreak of the disease in aquaculture. As a continuity of our previous studies, this paper describes the effects of dietary fenugreek (Trigonella foenum graecum) seeds on the skin mucosal antioxidant status and immune response of gilthead seabream (Sparus aurata L.). Fish were fed with four experimental diets: one a basal diet (control) and three diets with powdered fenugreek seeds incorporated in the fish feed at 1%, 5%, and 10%. After eight weeks of feeding, free radicals scavenging and antioxidant assays were assessed in skin mucus by measuring the peroxidation of phospholipid liposomes, hydroxyl radical and hydrogen peroxide scavenging, measurement of total antioxidant activity and the determination of antioxidant activity in a linoleic acid system. The skin mucosal immune response was evaluated by measuring the IgM levels and some enzymatic activities (peroxidase, antiprotease, protease, esterase, and ceruloplasmin). Our results demonstrated that fenugreek inclusion improved the hydroxyl radical scavenging capacity and conferred very high antioxidant activity. Besides, only the highest supplementation level (10%) was able to augment the peroxidase and protease activities confronted by a general decrement in the antiprotease activity in the experimental fed groups with 1% and 10%. These results suggest that the dietary administration of fenugreek at the higher inclusion dose enhances the skin mucosal immunity response and the antioxidant status of gilthead seabream a species with one of the highest rates of production in marine aquaculture. PMID- 29462749 TI - Effects of a probiotic (Bacillus licheniformis) on the growth, immunity, and disease resistance of Haliotis discus hannai Ino. AB - To study the effects of a probiotic (Bacillus lincheniformis) on the survival and growth of Haliotis discus hannai Ino, the expression levels of nonspecific immune genes and the resistance to Vibrio parahaemolyticus infection were assessed. Abalones (shell length: 27.64 +/- 1.59 mm, body weight: 4.17 +/- 0.32 g) were selected for use in an 8-week culture experiment and a 2-week V. parahaemolyticus artificial infection experiment. In both experiments, the control group (C) was fed with a basal feed and the experimental groups were fed with experimental food prepared by spraying the probiotic on the basal feed at different concentrations: 103 (B1), 105 (B2), and 107 (B3) cfu/mL. The survival rate, total number of blood lymphocytes, activity of acid phosphatase, and expression level of heat shock protein 70 were significantly higher in B1, B2, and B3 than in C (P < 0.05). The specific growth rate of shell length, food intake, food conversion rate, phagocytic activity of blood lymphocytes, activities of myeloperoxidase and catalase (CAT), and expression levels of CAT and thioredoxin peroxidase of abalones in B2 were significantly higher than those in B1 and C (P < 0.05). Although the level of O2- produced by the respiratory burst of blood lymphocytes in B2 was not significantly different from those in B1 and B3, they were significantly higher than that in C (P < 0.05). The activity of superoxide dismutase (SOD), the nitric oxide levels produced by the respiratory burst of blood lymphocytes, and the expression levels of Mn-SOD in B1 and B3 were significantly higher than those in C but significantly lower than those in B2 (P < 0.05). Fourteen days after infection with V. parahaemolyticus, the cumulative mortality of abalones in B2 was significantly lower than those in B1 and C (P < 0.05). These results indicate that the food containing 105 cfu/mL Bacillus licheniformis promoted food intake and growth of abalones and also improved their resistance to V. parahaemolyticus infection. Thus, B. licheniformis is a good potential probiotic. PMID- 29462750 TI - Personal exposure to fine particles (PM2.5) and respiratory inflammation of common residents in Hong Kong. AB - BACKGROUND: Given the lack of research on the personal exposure to fine particles (PM2.5) in Hong Kong, we examined the association between short-term personal exposure to PM2.5 and their constituents and inflammation in exhaled breath in a sample of healthy adult residents. METHOD: Forty-six participants underwent personal PM2.5 monitoring for averagely 6 days to obtain 276 samples. Fractional exhaled nitric oxide (FeNO), a biomarker of inflammation in exhaled breath, was measured at the end of each 24-h personal monitoring. PM2.5 chemical constituents, including organic carbon, elemental carbon, 16 polycyclic aromatic hydrocarbons (PAHs), and 6 phthalate esters, were speciated from the personal samples collected. A mixed-effects model was used to estimate the association of PM2.5 and their constituents with FeNO. The comparison was also made with parallel analyses using ambient concentrations. RESULTS: Personal exposures to PM2.5 (28.1 +/- 23.3 MUg/m3) were higher than the ambient levels (13.3 +/- 6.4 MUg/m3) monitored by stations. The composition profile and personal-to-ambient concentration ratio varied among subjects with different occupations. An interquartile range (IQR) change in personal exposure to PM2.5 was positively associated with 12.8% increase in FeNO (95% confidence interval, CI: 5.5-20.7%), while nil association was found for ambient PM2.5. Among the constituents measured, only the carcinogenic PAHs were significantly associated with 12% increase in FeNO responses (95% CI, 0.0-25.6%). CONCLUSION: In conclusion, our study provides the first understanding about personal exposure to PM2.5 and possible sources in Hong Kong. The results also showed that personal exposure to PM2.5 and c-PAHs were linked to increased FeNO levels among healthy adults. PMID- 29462751 TI - Primary splenic malignant lymphoma mimicking metastasis of rectosigmoid cancer: A case report. AB - INTRODUCTION: Primary splenic malignant lymphoma is quite a rare disease, and its preoperative diagnosis is difficult. CASE PRESENTATION: An 80-year-old man was diagnosed with advanced rectosigmoid cancer with liver and splenic metastases, for which he underwent single-incision laparoscopic high anterior resection for the primary rectosigmoid cancer. After chemotherapy, he underwent laparoscopy assisted splenectomy and open partial hepatectomy of segment 3 and segment 5/6 of the liver. The resected specimen of the spleen showed primary splenic malignant lymphoma. DISCUSSION: A diagnosis of primary splenic malignant lymphoma seems to be made only occasionally at splenectomy. Patients with primary splenic malignant lymphoma treated by curative resection at an early clinical stage have a more favorable prognosis. Laparoscopy-assisted splenectomy is useful for reducing surgical invasiveness. CONCLUSION: Primary splenic malignant lymphoma should be included among the differential diagnoses of splenic tumors in patients with colorectal cancer with multiple metastases. Curative resection might be a therapeutic option for the treatment of primary splenic malignant lymphoma. Laparoscopy-assisted splenectomy is a useful strategy for reducing surgical invasiveness. PMID- 29462752 TI - A rare case report of a typical variant ossifying fibromyxoid tumor (OFMT), located in the retroauricular perimastoid region. AB - INTRODUCTION: Ossifying fibromixoid tumor of soft parts (OFMT) is a rare soft tissue and bone tumor. In its classic form, is considered benign, nevertheless aggressive clinical behaviour tumors with a different cytoarchitectural features of a malignant variant, have been described.The classification contains "typical", "atypical" and "malignant" variants. METHODS: A CT ear scan without contrast enhancement was carried out (October 2015), with coronal, sagittal and 3D reconstructions. It was decided the removal of the neoformation with a simple dissection. RESULTS: In this report, we present a case of a typical variant OFMT localized in the retroauricular perimastoid region, with mastoid bone cortex not involved. CONCLUSIONS: Considering the extreme rarity of this "enigmatic" tumor which displays an uncertain line of differentiation, renders the differential diagnosis a true challenge. PMID- 29462753 TI - Paracecal hernia with intestinal ischemia treated with laparoscopic assisted surgery. AB - INTRODUCTION: Paracecal hernia is rare, and strangulation with ischemia has been infrequently observed in the limited number of published reports on paracecal hernias. PRESENTATION OF CASE: We describe a case of an incarcerated paracecal hernia with resultant ischemic bowel that was successfully treated with laparoscopic-assisted surgery. A 54-year-old man who had not undergone any surgery previously presented to our hospital with abdominal pain and vomiting. An abdominal computed tomographic scan showed evidence of an intestinal obstruction at a paracecal site. An emergency laparoscopic surgery demonstrated incarceration of a loop of the small bowel in the paracecal fossa. We removed the incarcerated small bowel from the paracecal fossa, noted that the tissue was necrotic, and resected this segment of bowel through a mini-laparotomy incision. The patient was discharged on the 13th postoperative day. DISCUSSION AND CONCLUSION: This case is unique in that the patient presented with small bowel strangulation, causing intestinal ischemia. Laparoscopic surgery is useful in the diagnosis of internal hernias and is also useful for the treatment of small bowel obstruction due to paracecal hernias complicated by ischemic bowel. PMID- 29462754 TI - A case of separation surgery with drainage tube-less (DRESS) esophagostomy for advanced cancer with a respiratory fistula. AB - INTRODUCTION: An esophagorespiratory fistula (ERF) can cause severe pneumonia or a lung abscess which progresses to life-threatening sepsis. A case of a patient with esophageal cancer and an esophagopulmonary fistula (EPF) who underwent separation surgery with drainage tube-less (DRESS) esophagostomy and was promptly started on definitive chemoradiotherapy (CRT) is reported. PRESENTATION OF CASE: A 79-year-old man visited a clinic with a month-long history of dysphagia. Esophageal cancer at the middle thoracic esophagus was detected, and invasion of the left main bronchus and lower lobe of the right lung was seen on contrast enhanced computed tomography (CT). Three weeks later, the patient was transferred to our hospital. CT showed a lung abscess in the lower lobe of the right lung that continued into the adjacent esophageal cancer. Due to the EPF, the patient underwent emergency surgery that consisted of esophageal separation surgery and double bilateral esophagostomy and enterostomy. Definitive CRT for the esophageal cancer was started from postoperative day 25. At six-month follow-up, the patient achieved relapse-free survival. DISCUSSION: Separation surgery with a DRESS esophagostomy provides good control of inflammation because of division of the respiratory tract from the alimentary tract, which allows prompt initiation of CRT. Alternatively, a DRESS esophagostomy allows patients to be free from any tube trouble. CONCLUSION: Separation surgery with a DRESS esophagostomy for an ERF is a promising method to improve patient quality of life that is less invasive, controls inflammation, and facilitates subsequent definitive CRT. PMID- 29462757 TI - Unveiling the pH dependent interaction between bolaamphiphiles (dicarboxylic acids) and C10TAB (decyltrimethylammonium bromide) in aqueous medium. AB - Development of stable self-assembled nanostructures (especially vesicles and liposomes), and understanding their physicochemical behaviors in aqueous solution is a long-standing topic of interest in chemical and biochemical research. In this progressive area, we report for the first-time formation of mixed micelles (at pH 12), and vesicles of anionic bolaamphiphiles (dicarboxylic acids viz. [Formula: see text] , with moderate values of n 10, 11, 12, and 14) in combination with a cationic surfactant decyltrimethylammonium bromide (C10TAB) in buffered aqueous medium at different pH (6.0, 6.5, 6.8, and 8.0 for bola 10, 11, 12, and 14, respectively). Three pH dependent states of the solutions are observed: clear (high pH > 8), turbid and translucent (mid pH ~ 6-8), and viscous inhomogeneous oil-like state (low pH < 6). The micelle size varies from 6.24 to 7.43 nm at pH 12, for vesicles the values are large (220-296 nm), and small (~30 70 nm) in the pH range of 6.0-8.0. The self-assembly formation properties of their mixtures are herein investigated using different techniques viz. UV-vis spectroscopy, fluorescence spectroscopy, dynamic light scattering, laser confocal scanning microscopy, and isothermal titration calorimetry. The formed vesicles are fairly polydisperse, and show overall spherical shape. Formation of the bilayer assemblies, and their conversion to mixed micelles by the temperature effect are observed from steady state fluorescence anisotropy measurements. Micellization of the mixed bola-C10TAB species is endothermic and fairly entropy controlled; their formation/deformation is pH sensitive. They have spherical morphologies, and once formed at the right pH they are found to be very stable in terms of time. Thus, these vesicles have prospects for encapsulation and delivery of materials like drugs, and other substrates by controling the acid-base conditions of the system environment. The formed mixed micelles, and vesicles are expected to be low toxic, and thus green materials in nature with wider application possibilites. PMID- 29462756 TI - BAG3 Overexpression and Cytoprotective Autophagy Mediate Apoptosis Resistance in Chemoresistant Breast Cancer Cells. AB - Target-specific treatment modalities are currently not available for triple negative breast cancer (TNBC), and acquired chemotherapy resistance is a primary obstacle for the treatment of these tumors. Here we employed derivatives of BT 549 and MDA-MB-468 TNBC cell lines that were adapted to grow in the presence of either 5-Fluorouracil, Doxorubicin or Docetaxel in an aim to identify molecular pathways involved in the adaptation to drug-induced cell killing. All six drug adapted BT-549 and MDA-MB-468 cell lines displayed cross resistance to chemotherapy and decreased apoptosis sensitivity. Expression of the anti apoptotic co-chaperone BAG3 was notably enhanced in two thirds (4/6) of the six resistant lines simultaneously with higher expression of HSP70 in comparison to parental controls. Doxorubicin-resistant BT-549 (BT-549rDOX20) and 5-Fluorouracil resistant MDA-MB-468 (MDA-MB-468r5-FU2000) cells were chosen for further analysis with the autophagy inhibitor Bafilomycin A1 and lentiviral depletion of ATG5, indicating that enhanced cytoprotective autophagy partially contributes to increased drug resistance and cell survival. Stable lentiviral BAG3 depletion was associated with a robust down-regulation of Mcl-1, Bcl-2 and Bcl-xL, restoration of drug-induced apoptosis and reduced cell adhesion in these cells, and these death-sensitizing effects could be mimicked with the BAG3/Hsp70 interaction inhibitor YM-1 and by KRIBB11, a selective transcriptional inhibitor of HSF-1. Furthermore, BAG3 depletion was able to revert the EMT-like transcriptional changes observed in BT-549rDOX20 and MDA-MB-468r5-FU2000 cells. In summary, genetic and pharmacological interference with BAG3 is capable to resensitize TNBC cells to treatment, underscoring its relevance for cell death resistance and as a target to overcome therapy resistance of breast cancer. PMID- 29462758 TI - Layer - Structured partially reduced graphene oxide sheathed mesoporous MoS2 particles for energy storage applications. AB - Mesoporous architectures are remarkable electrode materials for energy storage system due to their large number of active sites and high surface area. Here we report, mesoporous MoS2 particles (pore diameter 34.04 nm) well attached to the surface of thin layered reduced graphene oxide (rGO) via an ultrasonic chemical method for supercapacitor applications. The rGO not only increases the conductivity of MoS2 but also provides a substrate for the attachment of MoS2 with low aggregation. The porous MoS2 provides a large surface area and sufficient way for the fast transport of electrolyte ions toward electrode materials. As a result, the synthesized MoS2/rGO composites exhibited excellent electrochemical performance with a specific capacitance 314.5 F/g in 2M KOH aqueous solution at a scan rate of 10 mV/s and excellent specific capacitance retention (80.02%) after 1000 cycles in a three electrode system for energy storage applications. PMID- 29462755 TI - The human T-cell leukemia virus type-1 p30II protein activates p53 and induces the TIGAR and suppresses oncogene-induced oxidative stress during viral carcinogenesis. AB - In normal cells, aberrant oncogene expression leads to the accumulation of cytotoxic metabolites, including reactive oxygen species (ROS), which can cause oxidative DNA-damage and apoptosis as an intrinsic barrier against neoplastic disease. The c-Myc oncoprotein is overexpressed in many lymphoid cancers due to c myc gene amplification and/or 8q24 chromosomal translocations. Intriguingly, p53 is a downstream target of c-Myc and hematological malignancies, such as adult T cell leukemia/lymphoma (ATL), frequently contain wildtype p53 and c-Myc overexpression. We therefore hypothesized that p53-regulated pro-survival signals may thwart the cell's metabolic anticancer defenses to support oncogene activation in lymphoid cancers. Here we show that the Tp53-induced glycolysis and apoptosis regulator (TIGAR) promotes c-myc oncogene-activation by the human T cell leukemia virus type-1 (HTLV-1) latency-maintenance factor p30II, associated with c-Myc deregulation in ATL clinical isolates. TIGAR prevents the intracellular accumulation of c-Myc-induced ROS and inhibits oncogene-induced cellular senescence in ATL, acute lymphoblastic leukemia, and multiple myeloma cells with elevated c-Myc expression. Our results allude to a pivotal role for p53-regulated antioxidant signals as mediators of c-Myc oncogenic functions in viral and non-viral lymphoid tumors. PMID- 29462759 TI - Associations and predictions of readmission or death in acutely admitted older medical patients using self-reported frailty and functional measures. A Danish cohort study. AB - OBJECTIVE: To assess whether frailty in acutely admitted older medical patients, assessed by a self-report questionnaire and evaluation of functional level at discharge, was associated with readmission or death within 6 months after discharge. A second objective was to assess the predictive performance of models including frailty, functional level, and known risk factors. METHODS: A cohort study including acutely admitted older patients 65+ from seven medical and two acute medical units. The Tilburg Frailty Indicator (TFI), Timed-Up-and-Go (TUG), and grip strength (GS) exposure variables were measured. Associations were assessed using Cox regression with first unplanned readmission or death (all causes) as the outcome. Prediction models including the three exposure variables and known risk factors were modelled using logistic regression and C-statistics. RESULTS: Of 1328 included patients, 50% were readmitted or died within 6 months. When adjusted for gender and age, there was an 88% higher risk of readmission or death if the TFI scores were 8-13 points compared to 0-1 points (HR 1.88, CI 1.38;2.58). Likewise, higher TUG and lower GS scores were associated with higher risk of readmission or death. The area under the curve for the prediction models ranged from 0.64 (0.60;0.68) to 0.72 (0.68;0.76). CONCLUSION: In acutely admitted older medical patients, higher frailty assessed by TFI, TUG, and GS was associated with a higher risk of readmission or death within 6 months after discharge. The performance of the prediction models was mediocre, and the models cannot stand alone as risk stratification tools in clinical practice.

AB - In recent years, chimeric antigen receptor (CAR) modified T cells have been used as a treatment for haematological malignancies in several phase I and II trials and with Kymriah of Novartis and Yescarta of KITE Pharma, the first CAR T cell therapy products have been approved. Promising clinical outcomes have yet been tempered by the fact that many therapies may be prohibitively expensive to manufacture. The process is not yet defined, far from being standardised and often requires extensive manual handling steps. For academia, big pharma and contract manufacturers it is difficult to obtain an overview over the process strategies and their respective advantages and disadvantages. This review details current production processes being used for CAR T cells with a particular focus on efficacy, reproducibility, manufacturing costs and release testing. By undertaking a systematic analysis of the manufacture of CAR T cells from reported clinical trial data to date, we have been able to quantify recent trends and track the uptake of new process technology. Delivering new processing options will be key to the success of the CAR-T cells ensuring that excessive manufacturing costs do not disrupt the delivery of exciting new therapies to the wide possible patient cohort. PMID- 29462762 TI - Acetylcholinesterase of mangrove oyster Crassostrea rhizophorae: A highly thermostable enzyme with promising features for estuarine biomonitoring. AB - Enzyme biomarkers from several aquatic organisms have been used for assessing the exposure to contaminants at sublethal levels. Amongst them, the cholinesterases are commonly extracted from several organisms to evaluate/measure organophosphate and carbamate neurotoxic effects. Acetylcholinesterase (AChE; EC 3.1.1.7) is an enzyme of the group of serine esterases that acts on the hydrolysis of the neurotransmitter acetylcholine allowing the intermittence of the nerve impulses responsible for the neuronal communication. This enzyme is the main target for the action of some pesticides and the inhibition of its activity in bivalve mollusks may be used as biomarker due to their filter-feeding habit. In this context, the present study aimed to characterize physicochemical and kinetic parameters of the AChE extracted from gills and viscera of the oyster Crassostrea rhizophorae and investigate the in vitro effect of pesticides (dichlorvos, diazinon, chlorpyrifos, methyl-parathion, temephos, carbaryl, carbofuran, aldicarb, diflubenzuron and novaluron) in search for assessing its potential as biomarker. Specific substrates and inhibitors evidenced the predominance of AChE in both tissues. The optimum pH found for gills and viscera AChE were 8.0 and 8.5, respectively. The maximum peak of activity occurred at 70 degrees C for gill AChE and 75 degrees C for viscera AChE. The enzymes of both tissues presented remarkable thermostability. The Michaelis-Menten constant for both enzymes were 1.32 +/- 0.20 mM for gills and 0.43 +/- 0.12 mM for viscera. The Vmax values for gills and viscera were 53.57 +/- 1.72 and 27.71 +/- 1.15 mU/mg, respectively. The enzymes were able to reduce the activation energy to 9.75 kcal mol-1 (gills) and 11.87 kcal mol-1 (viscera) obtaining rate enhancements of 3.57 * 105 and 1.01 * 104, respectively, in relation to non-catalyzed reactions. Among the pesticides under study, the carbamates carbaryl and carbofuran exerted the strongest inhibitory effects on the enzyme activity achieving important degrees of inhibition at concentrations below national and international current regulations. The first observation of the effects of benzoylurea pesticides (diflubenzuron and novaluron) on AChE from mollusks is reported here. The gills AChE of C. rhizophorae showed potential to be specific biomarker for the carbamate carbaryl while the viscera AChE showed it for carbofuran. According to their features, these enzymes may be proposed as promising tools for estuarine monitoring as well as biocomponent of biosensor devices. PMID- 29462763 TI - Chronic impacts of TiO2 nanoparticles on Populus nigra L. leaf decomposition in freshwater ecosystem. AB - Titanium dioxide (TiO2) nanoparticles have been applied in diverse commercial products, which could lead to toxic effects on aquatic microbes and would inhibit some important ecosystem processes. The study aimed to investigate the chronic impacts of TiO2 nanoparticles with different concentrations (5, 50, and 500 mg L 1) on Populus nigra L. leaf decomposition in the freshwater ecosystem. After 50 d of decomposing, a significant decrease in decomposition rates was observed with higher concentrations of TiO2 nanoparticles. During the period of litter decomposition, exposure of TiO2 nanoparticles led to decreases in extracellular enzyme activities, which was caused by the reduction of microbial especially fungal biomass. In addition, the diversity and composition of the fungal community associated with litter decomposition were strongly affected by the concentrations of TiO2 nanoparticles. The diversity and composition of the fungal community associated with litter decomposition was strongly affected. The abundance of Tricladium chaetocladium decreased with the increasing concentrations of TiO2 nanoparticles, indicating the little contribution of the species to the litter decomposition. In conclusion, this study provided the evidence for the chronic exposure effects of TiO2 nanoparticles on the litter decomposition and further the functions of freshwater ecosystems. PMID- 29462764 TI - Bioinformatic prediction of plant-pathogenicity effector proteins of fungi. AB - Effector proteins are important virulence factors of fungal plant pathogens and their prediction largely relies on bioinformatic methods. In this review we outline the current methods for the prediction of fungal plant pathogenicity effector proteins. Some fungal effectors have been characterised and are represented by conserved motifs or in sequence repositories, however most fungal effectors do not generally exhibit high conservation of amino acid sequence. Therefore various predictive methods have been developed around: general properties, structure, position in the genomic landscape, and detection of mutations including repeat-induced point mutations and positive selection. A combinatorial approach incorporating several of these methods is often employed and candidates can be prioritised by either ranked scores or hierarchical clustering. PMID- 29462765 TI - Incidence of haematological malignancies, Eastern Cape Province; South Africa, 2004-2013. AB - BACKGROUND: The incidence of haematological malignancies in Africa's rapidly urbanising populations is insufficiently explored. Reliable population-based cancer statistics, however, continues to be a scarce resource in Africa and tends to be urban biased with limited rural coverage. In addition, many haematological malignancies are regarded as rare cancers, a sub-group that often affects the young disproportionately and require advanced diagnostic services and facilities able to deliver costly sophisticated treatments. This study provides a first attempt to estimate the incidence of haematological malignancies among the Eastern Cape Province population of South Africa. METHOD: Multiple public- and private sector data archives and resources were utilised to optimise the identification of incident cases, including clinical records; bone marrow; cytology; histology; flow cytometry and cytogenetic records. Crude incidence, age and gender-standardised rates are presented and comparison made with existing national data and select data from other economically developed countries and global institutions. RESULTS: A total of 3603 incident cases were identified between 2004 and 2013. Mature lymphoid malignancies accounted for approximately 60% (n = 2153), myeloma/plasma cell neoplasms 13% (n = 465), acute leukaemia 17% (n = 596), chronic myeloid leukaemia 4% (n = 155) and other myeloproliferative neoplasms 6% (n = 234) when stratified according to conventional groups. Most subtypes increase with age, with male excess. CONCLUSION: Haematological malignancies in the Eastern Cape Province show disparities in gender and pathology-specific incidence patterns. The present study suggest that haematological malignancies are not uncommon in this region and the incidence rate of at least one rare subtype, APL, is comparable with some European populations. PMID- 29462766 TI - Psychosocial stress increases craving for alcohol in social drinkers: Effects of risk-taking. AB - BACKGROUND: Exposure to stress and trait impulsivity are independent predictors of relapse in recovering alcoholics, but potential mechanisms that link these two risk-factors in terms of their putative additive or interactive contributions to relapse are not known. The aim of this study was to use a model of stress-induced relapse to test the hypothesis that acute psychosocial stress increases craving for alcohol in social drinkers. We also tested the hypothesis that change in craving could be explained by variability in impulsivity and risk-taking. METHODS: Participants completed questionnaires to assess drinking behaviour (Alcohol Dependence Questionnaire [ADQ]; and an Alcohol Use Disorders Identification Test [AUDIT]), craving (Desires for Alcohol Questionnaire [DAQ] and impulsivity (Barrett Impulsiveness Scale [BIS]). Participants also completed two computer tasks to assess risk-taking and impulsivity, the Balloon Analogue Risk Test (BART) and a continuous performance task (CPT). Participants then underwent the Trier Social Stress Test (TSST), and completed a final DAQ to assess post-stress craving. RESULTS: Participants showed an increase in craving following exposure to the TSST. In addition, risk-taking was positively correlated with change in craving. CONCLUSIONS: Our data suggests that acute psychosocial stress increases subjective craving in social drinkers, but that the effects may be trait-dependent, with stress-induced increases in craving correlated with risk-taking. PMID- 29462767 TI - Psychosocial and neural indicators of resilience among youth with a family history of substance use disorder. AB - BACKGROUND: Little is known regarding the combined influence of psychosocial and neural protective mechanisms against substance use. The present study examined the extent to which neuroimaging measures of disinhibition predicted resilience against binge drinking and marijuana use among youth with a family history of substance use disorder (SUD; FH+), accounting for psychosocial measures of behavioral control. METHODS: Participants were 57 FH+ youth from the Michigan Longitudinal Study categorized into resilient and high-risk groups based on patterns of weekly binge drinking and monthly marijuana use during early adulthood. Psychosocial measures of behavioral control (reactive control and externalizing behavior during early and late adolescence) and neural measures of disinhibition (Go/No-Go task and Monetary Incentive Delay Task (MIDT) measured through functional magnetic resonance imaging (fMRI)) were entered sequentially in hierarchical logistic regression models to predict resilient versus high-risk groups. RESULTS: Greater activation in the right dorsolateral prefrontal cortex (DLPFC) during correctly inhibited trials on the Go/No-Go task was a significant predictor of resilience (OR = 2.46, p < 0.05), over and above greater reactive control in early adolescence (OR = 4.96, p < 0.05) and lower externalizing behavior in late adolescence (OR = 0.64, p < 0.05). Neural activation in the ventral striatum associated with reward anticipation during the MIDT was not a significant predictor of resilience. CONCLUSIONS: Brain function in the right DLPFC associated with inhibitory control may be a neural indicator of resilience against elevated substance use among FH+ youth, even after accounting for psychosocial measures of behavioral control. PMID- 29462768 TI - Postpartum contraceptive use and interpregnancy interval among women with opioid use disorder. AB - OBJECTIVE: The purpose of this study was to describe postpartum contraceptive utilization patterns among women with OUD and evaluate the relationship between postpartum contraceptive method choice and interpregnancy interval. METHODS: A retrospective cohort study was conducted with women in Pennsylvania Medicaid with a diagnosis of OUD between 2008 and 2013. Postpartum contraceptive use within 90 days after delivery was identified through claims data and categorized by effectiveness (highly-effective, effective, and no method observed). Kaplan-Meier time-to-event analyses and multivariable-adjusted marginal Cox regression models were used to evaluate the relationship between postpartum contraceptive method choice and interpregnancy interval. Multivariable logistic regression analyses were used to identify risk factors predictive of a short interpregnancy interval (<=18 months). RESULTS: We identified 7805 women (9260 pregnancies) who had a diagnosis of OUD. Nearly three-quarters (74.5%) had no contraceptive method observed, 18.1% received an effective method, and only 7.4% received a highly effective method (LARC or female sterilization) during the postpartum period. In Kaplan-Meier analyses, no significant differences were found in the time-to-next pregnancy interval when an effective contraceptive method vs. no contraceptive method was used. In multivariable analysis, predictors of a significantly longer interpregnancy interval were LARC use (HR 0.43, 95% CI 0.26-0.69), gestational hypertension (HR 0.80, 95% CI 0.65-0.97), and age (HR 0.95, 95% CI 0.94-0.96). Approximately 20% of women with OUD had a short interpregnancy interval. CONCLUSION: Few women with OUD use highly-effective postpartum contraception, which is protective against short interpregnancy intervals.

AB - The study was carried out to determine Hg and Se concentrations in false killer whales stranded on the Estrecho de Magallanes, Chile, South America. Tissue samples of five mature specimens were analyzed (two females and three males). Mean Hg concentration in liver 1068 (234) MUg g-1 dry weight (DW) (standard deviation in parenthesis) was markedly higher than those in kidney 272 (152) MUg g-1 DW, lung 423 (325) MUg g-1 DW, spleen 725 (696) MUg g-1 DW, muscle 118 (94) MUg g-1 DW and testicle 18.0 (2.8) MUg g-1 DW. Mean Se concentration in liver, 398 (75) MUg g-1 DW, was higher than those in kidney 162 (69) MUg g-1 DW, lung 128 (84) MUg g-1 DW, spleen 268 (245) MUg g-1 DW, muscle 47 (38) MUg g-1 DW and testicle 25.4 (2.1) MUg g-1 DW. Positive correlations were found between Hg and Se molar concentrations in muscle, lung, spleen and kidney. Molar ratio of Se/Hg in liver, lung and muscle were <1, but those in kidney and testicle were markedly >1 suggesting a Se protection against Hg toxicity. In all the examined specimens Hg values exceeded the toxic thresholds defined for hepatic damage in marine mammals, with Se/Hg molar ratios below 1 implying limited protective action of Se. Generally, our results showed that individuals are carrying a significant burden, reflecting a high exposure to this toxic metal. This constitutes the first report on Hg and Se levels for a large subantarctic odontocete in South America region, providing insights into their contamination status and with information to the understanding of possible impacts on wild populations.

AB - The geochemical behavior of rare earth elements (REE) was investigated using weathering cells. The influence of sorption and precipitation on dissolved REE mobility and fractionation is evaluated using synthetic iron-oxides, carbonates, and phosphates. Sorption cell tests are conducted on the main lithologies of the expected waste rocks from the Montviel deposit. The sorbed materials are characterized using a scanning electron microscope (SEM) equipped with a microanalysis system (energy dispersive spectroscopy EDS) (SEM-EDS), X-ray diffraction (XRD), and X-ray absorption near edge structure (XANES) in order to understand the effect of the synthetic minerals on REE mobility. The results confirm that sorption and precipitation control the mobility and fractionation of REE. The main sorbent phases are the carbonates, phosphates (present as accessory minerals in the Montviel waste rocks), and iron oxides (main secondary minerals generated upon weathering of the Montviel lithologies). The XANES results show that REE are present as trivalent species after weathering. Thermodynamic equilibrium calculations results using Visual Minteq suggest that REE could precipitate as secondary phosphates (REEPO4).

AB - A novel photochromic diarylethene with a triazole-containing 2-(2'-phenoxymethyl) benzothiazole group has been synthesized via "click" reaction. The diarylethene exhibited good photochromism and photoswitchable fluorescence. Its fluorescence emission intensity was enhanced 7-fold by acids, accompanied by the red-shift of emission peak from 526nm to 566nm and the concomitant color change from dark to bright flavogreen. The diarylethene selectively formed a 1:1 metal complex with Al3+, resulting in a "turn-on" fluorescence signal. The complexation - reaction between Al3+ and the diarylethene is reversible with the binding constant of 2.73*103Lmol-1. The limit of detection (LOD) of Al3+ was determined to be 5.94*10 8molL-1. Based on this unimolecular platform, a logic circuit was fabricated using the fluorescence emission intensity at 572nm as the output and the combined stimuli of Al3+/EDTA and UV/Vis as the inputs.

AB - A series of novel 1,3-diaryltriazene-substituted sulfonamides was synthesized by reaction of diazonium salt of 4-amino benzenesulfonamide with substituted aromatic amines. The obtained 1,3-diaryltriazene-substituted sulfonamides were investigated as inhibitors of four selected human carbonic anhydrase (CA, EC 4.2.1.1) isoforms (hCA I, hCA II, hCA VII and hCA IX) are involved in various diseases such as glaucoma, epilepsy, retinitis pigmentosa, cancer, obesity, etc. All these sulfonamides were found to be potent inhibitors of the cytosolic isoform hCA II with low nanomolar to sub-nanomolar Kis in the range of 0.2-21.5 nM, as well as a moderate selectivity against other cytosolic isoforms hCA I and hCA VII, and great selectivity against membrane-bound isoform hCA IX was observed. Since hCA II is an important drug target for antiglaucoma agents and diuretics, these isoform-selective inhibitors may be considered of interest as tools for the development of new candidates for these conditions. PMID- 29462773 TI - Unmatched speed perceptions between overground and treadmill manual wheelchair propulsion in long-term manual wheelchair users. AB - BACKGROUND: Manual wheelchair (MWC) propulsion is increasingly assessed on a motorized treadmill (TM), which is often considered more ecologically valid than stationary rollers. However, no clear consensus on the similarities between overground (OG) and TM propulsion has yet been reached. Furthermore, no study has investigated the participants' perceptions of propelling a MWC on a TM compared to OG. RESEARCH QUESTION: The present study aims to assess the perception of speed when propelling on a TM vs OG, and to relate this perception to measured spatiotemporal variables, kinetics and work. METHODS: In this repeated-measures study, the propulsion's spatiotemporal variables, kinetics, and work of nineteen experienced wheelchair users with a spinal cord injury were compared between three conditions: 1) OG at a self-selected speed, 2) on a TM at a self-selected speed perceived as being similar to the OG speed (TMperceived), and 3) on a TM at the same speed as OG (TMmatched). Each variable was compared between conditions using an analysis of variance for repeated measures. RESULTS: All participants selected a lower speed for TMperceived than OG, with a difference of -0.6 m/s ( 44%). This adaptation may be due to a combination of two factors: 1) the absence of speed information, and 2) the feeling of urgency to grab the wheels during the recovery phase. The power output, work per cycle, and work per minute were also much lower on TMperceived than OG. However, in contrast to other work on MWC propulsion on a TM, the kinetic variables assessed were all similar between the OG and TMmatched conditions. SIGNIFICANCE: Training on a TM should be performed at a speed that matches the OG speed and not at a self-selected speed on the TM, which would reduce the power output and work and therefore reduce the efficiency of the training. PMID- 29462774 TI - Dual-task related gait changes in individuals with trans-tibial lower extremity amputation. AB - BACKGROUND: The improvement of gait and mobility are major rehabilitation goals following lower extremity amputations. However, when living in the community many daily activities require the multitasking of motor and cognitive tasks. The dual task paradigm can be used to evaluate the concurrent performance of mobility and cognitive tasks. RESEARCH QUESTION: The purpose of this study was to evaluate the effects of dual-task gait testing in older adults with trans-tibial amputations. METHODS: Twenty-four people (15 men, mean age +/- SD, 62.72 +/- 8.59) with trans tibial amputation walked on an electronic walkway at i) self-selected comfortable pace and ii) self-selected comfortable pace while counting backwards by threes from a number randomly selected between 100 and 150. Cognitive performance, in the form of corrected response rate, was also evaluated as a single-task. RESULTS: The dual-task testing produced poorer performance in velocity (single task = 58.15 +/- 23.16 cm/s, dual-task = 50.92 +/- 21.16 cm/s, p = 0.008), cadence (single-task = 76.65 +/- 15.84 steps/min, dual-task = 67.85 +/- 15.76 steps/min, p = 0.002) and stride time (single-task = 1094 +/- 458.28 ms, dual task = 1241.44 +/- 513.73 ms, p = 0.005). Step length, stance time and single limb support time symmetry were also affected, such that less time was spent on the amputated limb during the dual-task testing. SIGNIFICANCE: Dual-task testing demonstrated interference resulting in a poor performance in both gait and cognitive performance in trans-tibial amputees. Further research is suggested to evaluate the change in cognition-mobility effects over time and the relationship of this value to future adverse events such as falls and successful outcomes such as community ambulation and reintegration. PMID- 29462775 TI - Gait analysis in patients with chronic obstructive pulmonary disease: a systematic review. AB - BACKGROUND: Gait instability is a major fall-risk factor in patients with chronic obstructive pulmonary disease (COPD). Clinical gait analysis is a reliable tool to predict fall onsets. However, controversy still exists on gait impairments associated with COPD. RESEARCH QUESTION: Thus, the aims of this review were to evaluate the current understanding of spatiotemporal, kinematic and kinetic gait features in patients with COPD. METHODS: In line with PRISMA guidelines, a systematic literature search was performed throughout Web of Science, PubMed Medline, Scopus, PEDro and Scielo databases. We considered observational cross sectional studies evaluating gait features in patients with COPD as their primary outcome. Risk of bias and applicability of these papers were assessed according to the QUADAS-2 tool. RESULTS: Seven articles, cross-sectional studies published from 2011 to 2017, met the inclusion criteria. Sample size of patients with COPD ranged 14-196 (mean age range: 64-75 years). The main reported gait abnormalities were reduced step length and cadence, and altered variability of spatiotemporal parameters. Only subtle biomechanical changes were reported at the ankle level. SIGNIFICANCE: A convincing mechanistic link between such gait impairments and falls in patients with COPD is still lacking. The paucity of studies, small sample sizes, gender and disease status pooling were the main risk of biases affecting the results uncertainty. Two research directions emerged: stricter cohorts characterization in terms of COPD phenotype and longitudinal studies. Quantitative assessment of gait would identify abnormalities and sensorimotor postural deficiencies that in turn may lead to better falling prevention strategies in COPD. PMID- 29462776 TI - Maternal arsenic exposure and birth outcomes: A birth cohort study in Wuhan, China. AB - Maternal arsenic exposure leads to adverse birth outcomes, but the critical window of this susceptibility keeps unclear. To determine whether the associations between maternal arsenic exposure and birth outcomes were trimester specific, we conducted a birth cohort study of 1390 women from 2014 to 2016 in Wuhan, China. We examined associations between total urinary arsenic concentrations in three trimesters and birth weight, birth length and the risk of small for gestational age (SGA), and the differences of these associations across trimesters using generalized estimating equations. Maternal urinary arsenic concentrations varied across trimesters and were weakly correlated. Arsenic concentrations in the 3rd trimester, but not in the 1st and 2nd trimesters, were associated with birth outcomes. For each doubling of arsenic levels in the 3rd trimester, birth weight was decreased 24.27 g (95% confidence interval (CI): 46.99, -1.55), birth length was decreased 0.13 cm (95% CI: -0.22, -0.04), and the risk for SGA birth was increased 25% (95% CI: 1.03, 1.49). Further, stratified analyses indicated that these associations were only observed in female infants. Our findings indicate maternal arsenic levels in the 3rd trimester seemed to have significant impacts on birth outcomes, and also emphasize the public health interventions relevance to arsenic exposure in late pregnancy. PMID- 29462777 TI - Effects of water warming and acidification on bioconcentration, metabolization and depuration of pharmaceuticals and endocrine disrupting compounds in marine mussels (Mytilus galloprovincialis). AB - Warming and acidification are expected impacts of climate change to the marine environment. Besides, organisms that live in coastal areas, such as bivalves, can also be exposed to anthropogenic pollutants like pharmaceuticals (PhACs) and endocrine disrupting compounds (EDCs). In this study, the effects of warming and acidification on the bioconcentration, metabolization and depuration of five PhACs (sotalol, sulfamethoxazole, venlafaxine, carbamazepine and citalopram) and two EDCs (methylparaben and triclosan) were investigated in the mussel species (Mytilus galloprovincialis), under controlled conditions. Mussels were exposed to warming and acidification, as well as to the mixture of contaminants up to 15.7 MUg L-1 during 20 days; followed by 20 days of depuration. All contaminants bioconcentrated in mussels with levels ranging from 1.8 MUg kg-1 dry weight (dw) for methylparaben to 12889.4 MUg kg-1 dw for citalopram. Warming increased the bioconcentration factor (BCF) of sulfamethoxazole and sotalol, whereas acidification increased the BCF of sulfamethoxazole, sotalol and methylparaben. In contrast, acidification decreased triclosan levels, while both stressors decreased venlafaxine and citalopram BCFs. Warming and acidification facilitated the elimination of some of the tested compounds (i.e. sotalol from 50% in control to 60% and 68% of elimination in acidification and warming respectively). However, acidification decreased mussels' capacity to metabolize contaminants (i.e. venlafaxine). This work provides a first insight in the understanding of aquatic organisms' response to emerging contaminants pollution under warming and acidification scenarios. PMID- 29462778 TI - Coagulation behavior of humic acid in aqueous solutions containing Cs+, Sr2+ and Eu3+: DLS, EEM and MD simulations. AB - The coagulation behaviors of humic acid (HA) with Cs+ (10-500 mM), Sr2+ (0.8-10.0 mM) and Eu3+ (0.01-1.0 mM) at different pH values (2.8, 7.1 and 10.0) were acquired through a dynamic light scattering (DLS) technique combined with spectroscopic analysis and molecular dynamic (MD) simulations. The coagulation rate and the average hydrodynamic diameter () increased significantly as the concentration of nuclides increased. could be scaled to time t as ? ta at higher Sr2+ concentrations, which shows that HA coagulation is consistent with the diffusion-limited colloid aggregation (DLCA) model. Trivalent Eu3+ induced HA coagulation at a much lower concentration than bivalent Sr2+ and monovalent Cs+. The coagulation value ratio of Sr2+ and Eu3+ to Cs+ is almost proportional to Z 6, indicating that the HA coagulation process is generally consistent with the Schulze-Hardy rule. Spectroscopic analysis indicated that the complexation between nuclides and carboxylic/phenolic groups of HA molecules played important roles in the coagulation of HA. MD modelling suggested that Sr2+ and Eu3+ ions increased the coagulation process through the formation of intra- or inter molecular bridges between negatively charged HA molecules, whereas for Cs+, no inter-molecular bridges were formed. This work offers new insight into the interactions between HA and radionuclides and provides a prediction for the roles of HA in the transportation and elimination of radionuclides in severely polluted environments. PMID- 29462779 TI - Effects of vagus nerve stimulation on heart rate variability in children with epilepsy. AB - PURPOSE: The aim of this study was to evaluate the effects of vagus nerve stimulation (VNS) on heart rate variability (HRV) in children with epilepsy. METHODS: The subgroups of HRV, namely time domain (Standard deviation of NN interval (SDNN), SDNN index, Standard deviation of the averages of NN intervals (SDANN), Root mean square of successive differences (RMMSD), Adjacent NN intervals differing by more than 50 ms in the entire recording divided by the total number of all NN intervals (PNN50), triangular index) and frequency domain (Low-frequency (LF), High-frequency (HF), LF/HF), were investigated in 20 pediatric patients before and after 6 and 12months of VNS treatment during day and night by comparing their data with those of 20 control subjects. In addition, subgroups of age, epilepsy duration and localization, and antiepileptic drugs (AEDs) were also evaluated if they had further effects on basal HRV levels. RESULTS: Increased heart rates (HRs); decreased SDNN, SDANN, RMMSD, and PNN50; and increased LF/HF ratios were identified before VNS therapy (p<0.05). Even though remarkable improvement was seen after 6months of VNS treatment (p<0.05), no further changes were observed in 12-month compared with 6-month levels (p>0.05) in all parameters, still even significantly lower than those of controls (p<0.05). Longer duration of epilepsy and localization of epileptic focus, such as in the temporal lobe, were also found to further contribute to diminished basal HRV levels (p<0.05). CONCLUSION: The cardiovascular system is under deep sympathetic influence in children with epilepsy. Although VNS seems to provide a substantial improvement by achieving increased parasympathetic effects in short term therapy, the levels were still lower than those of healthy children after either short- or long-term therapy. Therefore, impaired cardiovascular autonomic regulation may be associated with the epileptic process itself as well as with the contribution of some additional factors. Overall, different aspects such as age, epilepsy duration, epileptic focus, seizure frequency, and AEDs should also be considered for their further possible effects on HRV during VNS therapy. PMID- 29462780 TI - Sensitive analytical method to quantify clindamycin in plasma and microdialysate samples: Application in a preclinical pharmacokinetic study. AB - Clindamycin is widely used in antimicrobial prophylaxis to prevent surgical site infections. Adequate subcutaneous free tissue concentrations should reach therapeutic levels, which have to be maintained throughout the surgical procedure for antibiotic prophylaxis to be efficient. A method was developed and validated using high performance liquid chromatography coupled to a mass spectrometry to determine clindamycin concentrations in two biological matrices: plasma, for drug monitoring, and subcutaneous microdialysate, to determine free concentrations at the incision site. Gradient separation of clindamycin was carried out using a reverse phase C18 column eluted with a mixture of mobile phases (1% formic acid in water and 1% formic acid in acetonitrile). The monitored transitions were m/z 425.3 > 377.3 for clindamycin, and m/z 407 > 359 for lincomycin, used as the internal standard for plasma samples. Linearity was reached in the 0.5-100 MUg/mL range for plasma and 25-1000 ng/mL for microdialysate samples. The method was selective, precise, and accurate, and was successfully employed in a preliminary pharmacokinetics study to investigate plasma and subcutaneous clindamycin penetration, determined by microdialysis, after intravenous administration of a 50 mg/kg dose to Wistar rats. PMID- 29462781 TI - Tripolyphosphate-crosslinked chitosan/poly (ethylene oxide) electrospun nanofibrous mats as a floating gastro-retentive delivery system for ranitidine hydrochloride. AB - The present study describes the fabrication of Tripolyphosphate (TPP)-crosslinked nanofibrous mats based on chitosan for use as a floating gastro-retentive delivery system. TPP-crosslinked chitosan (CH)/poly (ethylene oxide) (PEO)- ranitidine hydrochloride (RH) electrospun nanofibers (75.27 +/- 2.10 nm) were prepared by electrospinning 70% v/v acetic acid solutions, and followed by crosslinking by TPP anions. The mechanical, structural and morphological properties of the prepared nanofibers were evaluated via tensile testing, XRD, FT IR, TGA, NMR, AFM and SEM experimental techniques. The prepared nanofibrous mats showed a pH sensitive swelling profile with maximum water absorbing at pH 1.2. Results obtained from above experimental techniques indicated that crosslinking process did not significantly altered morphological property of nanofibers but rather decreased their diameter and swelling degree, and increased their mechanical properties, thermal stability and bioadhesive strength. Viscosity measurements showed that the addition of PEO and RH to the chitosan solution, depending to its concentration lead to decrease in the viscosity of its solution. Also, floating test showed that the prepared nanofibrous mats remain floated onto surface of the dissolution medium for more than 48 h. Based on in- vitro drug release data analysis, TPP-crosslinked CH/PEO nanofibrous mats decreased initial burst release and it was exhibited a sustained release profile for the RH from the TPP-crosslinked CH/PEO-RH electrospun nanofibrous mats. PMID- 29462782 TI - Utilizing ELISA-plate based immunopurification and liquid chromatography-tandem mass spectrometry for the urinary detection of short- and long acting human insulin analogues. AB - The measurement of human insulin and its synthetic analogues in biological matrices has become increasingly important not only in clinical fields but also in doping control. The use of insulin and its analogues have been included in the list of prohibited substances published by the World Anti-Doping Agency (WADA). This study describes a qualitative method for detection of insulin analogues (lispro, aspart, glulisine, glargine, degludec, detemir) in human urine. The sample preparation consists of a preconcentration step using ultrafiltration followed by an immunoaffinity extraction with an antibody precoated ELISA plate. The obtained extracts are analyzed by conventional high-performance liquid chromatography-electrospray tandem mass spectrometry (LC-ESI-MS/MS). The limits of detection range between 10 pg/ml and 150 pg/ml. The applicability of the method was proven by the analysis of real urine samples obtained from diabetic patients treated with synthetic insulin analogues. PMID- 29462783 TI - Milling and comilling Praziquantel at cryogenic and room temperatures: Assessment of the process-induced effects on drug properties. AB - This study is a comprehensive evaluation of praziquantel (PZQ) behavior upon grinding considering the influence of milling temperature (cryogenic vs room temperature), frequency and time and presence of polymers (milled raw PZQ vs comilled PZQ/povidone and PZQ/crospovidone at 50:50 w/w) on two experimental responses (residual crystallinity and PZQ recovery). To this aim a full factorial design was set up and the responses of the experimental design were statistically assessed. The powder temperature, measured in different milling conditions, was found to increase with increasing milling frequency and time, up to a maximum recorded value of 46.9 degrees C (after 90 min at R.T.), for all the three powder systems. When PZQ was ground in RT environment, the recovery was 100%, independently from frequency and time of milling. Its residual crystallinity remained pronounced (>70%) upon milling, even if treated at the most severe conditions. Conversely, when the drug was milled in presence of the polymers, it showed a higher tendency to degradation and amorphysation, independently from the choice of the polymer. The use of cryogenic conditions, operating at temperatures lower than PZQ glass transition, permitted to dramatically reduce PZQ residual crystallinity when the drug was ground by itself. In the case of binary mixtures, the switch to a cryogenic environment did not affect significantly the experimental responses, but permitted to obtain a more predictable trend of both drug recovery and residual crystallinity when varying time and frequency of milling. PMID- 29462784 TI - Transient receptor potential vanilloid 4 (TRPV4) activation by arachidonic acid requires protein kinase A-mediated phosphorylation. AB - Transient receptor potential vanilloid 4 (TRPV4) is a Ca2+-permeable channel of the transient receptor potential (TRP) superfamily activated by diverse stimuli, including warm temperature, mechanical forces, and lipid mediators such as arachidonic acid (AA) and its metabolites. This activation is tightly regulated by protein phosphorylation carried out by various serine/threonine or tyrosine kinases. It remains poorly understood how phosphorylation differentially regulates TRPV4 activation in response to different stimuli. We investigated how TRPV4 activation by AA, an important signaling process in the dilation of coronary arterioles, is affected by protein kinase A (PKA)-mediated phosphorylation at Ser-824. Wildtype and mutant TRPV4 channels were expressed in human coronary artery endothelial cells (HCAECs). AA-induced TRPV4 activation was blunted in the S824A mutant but was enhanced in the phosphomimetic S824E mutant, whereas the channel activation by the synthetic agonist GSK1016790A was not affected. The low level of basal phosphorylation at Ser-824 was robustly increased by the redox signaling molecule hydrogen peroxide (H2O2). The H2O2 induced phosphorylation was accompanied by an enhanced channel activation by AA, and this enhanced response was largely abolished by PKA inhibition or S824A mutation. We further identified a potential structural context dependence of Ser 824 phosphorylation-mediated TRPV4 regulation involving an interplay between AA binding and the possible phosphorylation-induced rearrangements of the C-terminal helix bearing Ser-824. These results provide insight into how phosphorylation specifically regulates TRPV4 activation. Redox-mediated TRPV4 phosphorylation may contribute to pathologies associated with enhanced TRPV4 activity in endothelial and other systems. PMID- 29462785 TI - The plant sesquiterpene lactone parthenolide inhibits Wnt/beta-catenin signaling by blocking synthesis of the transcriptional regulators TCF4/LEF1. AB - The Wnt/beta-catenin pathway is essential for embryonic development and homeostasis, but excessive activation of this pathway is frequently observed in various human diseases, including cancer. Current therapeutic drugs targeting the Wnt pathway often lack sufficient efficacy, and new compounds targeting this pathway are therefore greatly needed. Here we report that the plant-derived natural product parthenolide (PTL), a sesquiterpene lactone, inhibits Wnt signaling. We found that PTL dose-dependently inhibits Wnt3a- and CHIR99021 induced transcriptional activity assessed with the T-cell factor (TCF)/lymphoid enhancer factor (LEF) firefly luciferase (TOPFlash) assay in HEK293 cells. Further investigations revealed that PTL decreases the levels of the transcription factors TCF4/LEF1 without affecting beta-catenin stability or subcellular distribution. Moreover, this effect of PTL on TCF4/LEF1 was related to protein synthesis rather than to proteasome-mediated degradation. Of note, siRNA-mediated knockdown of RPL10, a ribosome protein PTL binds, substantially decreased TCF4/LEF1 protein levels and also Wnt3a-induced TOPFlash activities, suggesting a potential mechanism by which PTL may repress Wnt/beta-catenin signaling. In summary, PTL binds RPL10 and thereby potently inhibits the Wnt/beta catenin pathway. PMID- 29462786 TI - Distinct properties underlie flavin-based electron bifurcation in a novel electron transfer flavoprotein FixAB from Rhodopseudomonas palustris. AB - A newly recognized third fundamental mechanism of energy conservation in biology, electron bifurcation, uses free energy from exergonic redox reactions to drive endergonic redox reactions. Flavin-based electron bifurcation furnishes low potential electrons to demanding chemical reactions, such as reduction of dinitrogen to ammonia. We employed the heterodimeric flavoenzyme FixAB from the diazotrophic bacterium Rhodopseudomonas palustris to elucidate unique properties that underpin flavin-based electron bifurcation. FixAB is distinguished from canonical electron transfer flavoproteins (ETFs) by a second FAD that replaces the AMP of canonical ETF. We exploited near-UV-visible CD spectroscopy to resolve signals from the different flavin sites in FixAB and to interrogate the putative bifurcating FAD. CD aided in assigning the measured reduction midpoint potentials (E degrees values) to individual flavins, and the E degrees values tested the accepted model regarding the redox properties required for bifurcation. We found that the higher-E degrees flavin displays sequential one-electron (1-e-) reductions to anionic semiquinone and then to hydroquinone, consistent with the reactivity seen in canonical ETFs. In contrast, the lower-E degrees flavin displayed a single two-electron (2-e-) reduction without detectable accumulation of semiquinone, consistent with unstable semiquinone states, as required for bifurcation. This is the first demonstration that a FixAB protein possesses the thermodynamic prerequisites for bifurcating activity, and the separation of distinct optical signatures for the two flavins lays a foundation for mechanistic studies to learn how electron flow can be directed in a protein environment. We propose that a novel optical signal observed at long wavelength may reflect electron delocalization between the two flavins. PMID- 29462787 TI - Mechanistic insights into transferable polymyxin resistance among gut bacteria. AB - Polymyxins such as colistin are antibiotics used as a final line of defense in the management of infections with multidrug-resistant Gram-negative bacteria. Although natural resistance to polymyxins is rare, the discovery of a mobilized colistin resistance gene (mcr-1) in gut bacteria has raised significant concern. As an intramembrane enzyme, MCR-1 catalyzes the transfer of phosphoethanolamine (PEA) to the 1 (or 4')-phosphate group of the lipid A moiety of lipopolysaccharide, thereby conferring colistin resistance. However, the structural and biochemical mechanisms used by this integral membrane enzyme remain poorly understood. Here, we report the modeled structure of the full length MCR-1 membrane protein. Together with molecular docking, our structural and functional dissection of the complex of MCR-1 with its phosphatidylethanolamine (PE) substrate suggested the presence of a 12 residue containing cavity for substrate entry, which is critical for both enzymatic activity and its resultant phenotypic resistance to colistin. More importantly, two periplasm-facing helices (PH2 and PH2') of the trans-membrane domain were essential for MCR-1 activity. MALDI-TOF MS and thin-layer chromatography assays provide both in vivo and in vitro evidence that MCR-1 catalyzes the transfer of PEA from the PE donor substrate to its recipient substrate lipid A. Also, the chemical modification of lipid A species was detected in clinical species of bacteria carrying mcr-1 Our results provide mechanistic insights into transferable MCR-1 polymyxin resistance, raising the prospect of rational design of small molecules that reverse bacterial polymyxin resistance, as a last-resort clinical option to combat pathogens with carbapenem resistance. PMID- 29462789 TI - Positioning the 5'-flap junction in the active site controls the rate of flap endonuclease-1-catalyzed DNA cleavage. AB - Flap endonucleases catalyze cleavage of single-stranded DNA flaps formed during replication, repair, and recombination and are therefore essential for genome processing and stability. Recent crystal structures of DNA-bound human flap endonuclease (hFEN1) offer new insights into how conformational changes in the DNA and hFEN1 may facilitate the reaction mechanism. For example, previous biochemical studies of DNA conformation performed under non-catalytic conditions with Ca2+ have suggested that base unpairing at the 5'-flap:template junction is an important step in the reaction, but the new structural data suggest otherwise. To clarify the role of DNA changes in the kinetic mechanism, we measured a series of transient steps, from substrate binding to product release, during the hFEN1 catalyzed reaction in the presence of Mg2+ We found that whereas hFEN1 binds and bends DNA at a fast, diffusion-limited rate, much slower Mg2+-dependent conformational changes in DNA around the active site are subsequently necessary and rate-limiting for 5'-flap cleavage. These changes are reported overall by fluorescence of 2-aminopurine at the 5'-flap:template junction, indicating that local DNA distortion (e.g. disruption of base stacking observed in structures), associated with positioning the 5'-flap scissile phosphodiester bond in the hFEN1 active site, controls catalysis. hFEN1 residues with distinct roles in the catalytic mechanism, including those binding metal ions (Asp-34 and Asp-181), steering the 5'-flap through the active site and binding the scissile phosphate (Lys-93 and Arg-100), and stacking against the base 5' to the scissile phosphate (Tyr-40), all contribute to these rate-limiting conformational changes, ensuring efficient and specific cleavage of 5'-flaps. PMID- 29462788 TI - Unraveling the sequence of cytosolic reactions in the export of GspB adhesin from Streptococcus gordonii. AB - Many pathogenic bacteria, including Streptococcus gordonii, possess a pathway for the cellular export of a single serine-rich-repeat protein that mediates the adhesion of bacteria to host cells and the extracellular matrix. This adhesin protein is O-glycosylated by several cytosolic glycosyltransferases and requires three accessory Sec proteins (Asp1-3) for export, but how the adhesin protein is processed for export is not well understood. Here, we report that the S. gordonii adhesin GspB is sequentially O-glycosylated by three enzymes (GtfA/B, Nss, and Gly) that attach N-acetylglucosamine and glucose to Ser/Thr residues. We also found that modified GspB is transferred from the last glycosyltransferase to the Asp1/2/3 complex. Crystal structures revealed that both Asp1 and Asp3 are related to carbohydrate-binding proteins, suggesting that they interact with carbohydrates and bind glycosylated adhesin, a notion that was supported by further analyses. We further observed that Asp1 also has an affinity for phospholipids, which is attenuated by Asp2. In summary, our findings support a model in which the GspB adhesin is sequentially glycosylated by GtfA/B, Nss, and Gly and then transferred to the Asp1/2/3 complex in which Asp1 mediates the interaction of the Asp1/2/3 complex with the lipid bilayer for targeting of matured GspB to the export machinery.

AB - Peroxidases are considered essential agents of lignin degradation by white-rot basidiomycetes. However, low-molecular-weight oxidants likely have a primary role in lignin breakdown because many of these fungi delignify wood before its porosity has sufficiently increased for enzymes to infiltrate. It has been proposed that lignin peroxidases (LPs, EC 1.11.1.14) fulfill this role by oxidizing the secreted fungal metabolite veratryl alcohol (VA) to its aryl cation radical (VA+*), releasing it to act as a one-electron lignin oxidant within woody plant cell walls. Here, we attached the fluorescent oxidant sensor BODIPY 581/591 throughout beads with a nominal porosity of 6 kDa and assessed whether peroxidase generated aryl cation radical systems could oxidize the beads. As positive control, we used the 1,2,4,5-tetramethoxybenzene (TMB) cation radical, generated from TMB by horseradish peroxidase. This control oxidized the beads to depths that increased with the amount of oxidant supplied, ultimately resulting in completely oxidized beads. A reaction-diffusion computer model yielded oxidation profiles that were within the 95% confidence intervals for the data. By contrast, bead oxidation caused by VA and the LPA isozyme of Phanerochaete chrysosporium was confined to a shallow shell of LP-accessible volume at the bead surface, regardless of how much oxidant was supplied. This finding contrasted with the modeling results, which showed that if the LP/VA system were to release VA+*, it would oxidize the bead interiors. We conclude that LPA releases insignificant quantities of VA+* and that a different mechanism produces small ligninolytic oxidants during white rot. PMID- 29462791 TI - The cellular chloride channels CLIC1 and CLIC4 contribute to virus-mediated cell motility. AB - Ion channels regulate many aspects of cell physiology, including cell proliferation, motility, and migration, and aberrant expression and activity of ion channels is associated with various stages of tumor development, with K+ and Cl- channels now being considered the most active during tumorigenesis. Accordingly, emerging in vitro and preclinical studies have revealed that pharmacological manipulation of ion channel activity offers protection against several cancers. Merkel cell polyomavirus (MCPyV) is a major cause of Merkel cell carcinoma (MCC), primarily because of the expression of two early regulatory proteins termed small and large tumor antigens (ST and LT, respectively). Several molecular mechanisms have been attributed to MCPyV-mediated cancer formation but, thus far, no studies have investigated any potential link to cellular ion channels. Here we demonstrate that Cl- channel modulation can reduce MCPyV ST induced cell motility and invasiveness. Proteomic analysis revealed that MCPyV ST up-regulates two Cl- channels, CLIC1 and CLIC4, which when silenced, inhibit MCPyV ST-induced motility and invasiveness, implicating their function as critical to MCPyV-induced metastatic processes. Consistent with these data, we confirmed that CLIC1 and CLIC4 are up-regulated in primary MCPyV-positive MCC patient samples. We therefore, for the first time, implicate cellular ion channels as a key host cell factor contributing to virus-mediated cellular transformation. Given the intense interest in ion channel modulating drugs for human disease. This highlights CLIC1 and CLIC4 activity as potential targets for MCPyV-induced MCC.

AB - Various phytohormones control plant growth and development and mediate biotic and abiotic stress responses. Gretchen Hagen 3 (GH3) acyl acid amido synthetases are plant enzymes that typically conjugate amino acids to indole-3-acetic acid (IAA) or jasmonic acid (JA) to inactivate or activate these phytohormones, respectively; however, the physiological and biological roles of many of these enzymes remain unclear. Using a biochemical approach, we found that the Arabidopsis thaliana GH3.15 (AtGH3.15) preferentially uses indole-3-butyric acid (IBA) and glutamine as substrates. The X-ray crystal structure of the AtGH3.15.AMP complex, modeling of IBA in the active site, and biochemical analysis of site-directed mutants provide insight on active site features that lead to AtGH3.15's preference for IBA. Assay-based in planta analysis of AtGH3.15 overexpressing lines indicated that their root elongation and lateral root density were resistant to IBA treatment but not to treatment with either IAA or JA. These findings suggest that AtGH3.15 may play a role in auxin homeostasis by modulating the levels of IBA for peroxisomal conversion to IAA. Analysis of AtGH3.15 promoter-driven yellow fluorescent protein reporter lines revealed that AtGH3.15 is expressed at significant levels in seedlings, roots, and parts of the siliques. We conclude that AtGH3.15 is unique in the GH3 protein family for its role in modifying IBA in auxin homeostasis and that it is the first GH3 protein shown to primarily modify a plant growth regulator other than IAA and JA. PMID- 29462794 TI - Filling the mitochondrial copper pool. AB - A host of critical metalloproteins reside in mitochondria, where metallation occurs within the organelle after protein import. Although the pathways by which proteins are imported into the mitochondria are well known, the mechanisms by which their metal partners are imported are more obscure. A new study by Boulet et al. demonstrates that the mammalian SLC25A3 inner membrane transporter, previously known as a phosphate carrier, is also a functional Cu(I) importer, clarifying the source of mitochondrial copper and raising new questions about cellular copper homeostasis. PMID- 29462793 TI - The human platelet antigen-1b (Pro33) variant of alphaIIbbeta3 allosterically shifts the dynamic conformational equilibrium of this integrin toward the active state. AB - Integrins are heterodimeric cell-adhesion receptors comprising alpha and beta subunits that transmit signals allosterically in both directions across the membrane by binding to intra- and extracellular components. The human platelet antigen-1 (HPA-1) polymorphism in alphaIIbbeta3 arises from a Leu -> Pro exchange at residue 33 in the genu of the beta3 subunit, resulting in Leu33 (HPA-1a) or Pro33 (HPA-1b) isoforms. Although clinical investigations have provided conflicting results, some studies have suggested that Pro33 platelets exhibit increased thrombogenicity. Under flow-dynamic conditions, the Pro33 variant displays prothrombotic properties, characterized by increased platelet adhesion, aggregate/thrombus formation, and outside-in signaling. However, the molecular events underlying this prothrombotic phenotype have remained elusive. As residue 33 is located >80 A away from extracellular binding sites or transmembrane domains, we hypothesized that the Leu -> Pro exchange allosterically shifts the dynamic conformational equilibrium of alphaIIbbeta3 toward an active state. Multiple microsecond-long, all-atom molecular dynamics simulations of the ectodomain of the Leu33 and Pro33 isoforms provided evidence that the Leu -> Pro exchange weakens interdomain interactions at the genu and alters the structural dynamics of the integrin to a more unbent and splayed state. Using FRET analysis of fluorescent proteins fused with alphaIIbbeta3 in transfected HEK293 cells, we found that the Pro33 variant in its resting state displays a lower energy transfer than the Leu33 isoform. This finding indicated a larger spatial separation of the cytoplasmic tails in the Pro33 variant. Together, our results indicate that the Leu -> Pro exchange allosterically shifts the dynamic conformational equilibrium of alphaIIbbeta3 to a structural state closer to the active one, promoting the fully active state and fostering the prothrombotic phenotype of Pro33 platelets. PMID- 29462795 TI - Positive zip coding in small protein translocation. AB - Most newly synthesized proteins destined for the secretory pathway contain a signal peptide (SP) that triggers cotranslational translocation into the endoplasmic reticulum (ER). However, how small polypeptides undergo ER translocation is not fully understood. In this issue of JBC, Guo et al. describe a mechanism for posttranslational translocation of small secretory proteins featuring a positive charge within the SP N-terminal region. Defects in this element disrupt proper secretion and explain the effects of genetic mutations associated with one type of diabetes. PMID- 29462796 TI - P38/TRHr-Dependent Regulation of TPO in Thyroid Cells Contributes to the Hypothyroidism of Triclosan-Treated Rats. AB - BACKGROUND/AIMS: Triclosan, as an antimicrobial agent and a potential endocrine disruptor, has been used extensively in diverse products, resulting in widespread human exposure. In recent years, studies suggest that triclosan could disturb thyroid functions and decline thyroid hormones (THs). METHODS: To verify our hypothesis that the MAPK pathway may function significantly in triclosan-induced hypothyroidism, Sprague-Dawley rats were gavaged with triclosan for 31 consecutive days; Nthy-ori 3-1 cells were treated with triclosan in the presence/absence of NAC, inhibitors (SB203580 and SB202474), or TRHr siRNA. Tissues and/or cells were analyzed by several techniques including transmission electron microscopy, confocal laser scanning microscopy, gene silencing, western blot, and real-time PCR. RESULTS: Triclosan led to histopathologic changes in the thyroid and decreases in triiodothyronine (T3) and thyroxine (T4). Triclosan stimulated ROS production and oxidative stress occurrence, thereby activating the p38 pathway in vivo and in vitro. Thyrotropin releasing hormone receptor (TRHr) was induced when the p38 pathway was activated, and was suppressed when that pathway was inhibited. Moreover, thyroid peroxidase (TPO) was restrained and modulated by the p38/TRHr pathway after triclosan treatment. Furthermore, deiodinase 3 (D3) and hepatic enzymes (Ugt2b1, CYP1a1, CYP1a2, CYP2b1, CYP3a1, and Sult1e1) were also induced by triclosan. CONCLUSION: Taken together, p38/TRHr dependent regulation of TPO in thyroid cells contributes to the hypothyroidism of triclosan-treated rats. PMID- 29462797 TI - Functional SNP in the 3'UTR of PON1 is Associated with the Risk of Calcific Aortic Valve Stenosis via MiR-616. AB - BACKGROUND/AIMS: Previous studies have examined the associations between the single nucleotide polymorphism in the Paraoxonase 1 (PON1) gene and development of calcific aortic valve stenosis (CAVS). The association between functional SNP in 3'UTR of PON1 and the risk of CAVS, however, is unclear. In this study, we investigated the role of SNP in the regulation of PON1 expression via miR-616, as well as the association of SNP with the risk of CAVS. METHODS: Two hundred and sixteen patients with CAVS and 243 CAVS-free participants were recruited in this study.They all obtained transthoracic echocardiogram and the ejection fraction (EF) and aortic valve area were recorded and analyzed. The PON1 expression were measured by western blot, Quantitative Real-Time Polymerase Chain Reaction were used to examine the transcriptional activity of miR-616 and PON1. Differences between CVAS patients and controls in terms of genotype frequency distribution and the estimates of Hardy-Weinberg equilibrium were evaluated using chi-square tests. Logistic regression modeling was used to determine the association between the independent effect of rs3735590 SNP and the interaction between genotype, PON1 activity, and other covariates on lipids and CAVS risk. All statistical analyses were performed using SPSS, version 17.0.1 for Windows (SPSS Inc., Chicago, IL). A p value of < 0 .05 was considered significant for all analyses. RESULTS: This study confirmed that PON1 is a validated target gene of miR-616 in liver cells. The relative quantification representing the expression of PON1 mRNA and the serum level of PON1 protein was decreased in the TT genotype. Moreover, the expression of PON1 had a negative regulatory relationship with the expression of miR-616(r=-0.3959, P<0.05) in human tissues. The patients with CT OR TT genotype at loci rs3735590 had a lower risk of CAVS than patients with the CC genotype. CONCLUSIONS: Our results suggest that functional SNP in the 3'UTR of PON1 regulates the expression of PON1 via miR-616, and such SNP is associated with the risk of CAVS in human. PMID- 29462798 TI - Serum FGF21 Is Associated with Future Cardiovascular Events in Patients with Coronary Artery Disease. AB - OBJECTIVES: To investigate whether serum fibroblast growth factor 21 (FGF21) levels can be used to predict the future development of major adverse cardiovascular events (MACEs). METHODS: This study included 253 patients who received subsequent follow-up, and complete data were collected for 234 patients. Independent predictors of MACEs were identified by using the Cox proportional hazards regression analysis. The prognostic value of FGF21 levels for MACEs was evaluated by Kaplan-Meier survival analysis. RESULTS: Of 229 patients finally enrolled in the analysis, 27/60 without coronary artery disease (CAD) at baseline experienced a MACE, and 132/169 patients with CAD at baseline experienced a MACE. Among patients with CAD at baseline, serum FGF21 levels were significantly higher in patients with MACEs (p < 0.05) than in patients without MACEs. Kaplan-Meier survival analysis showed patients with a higher serum FGF21 had a significantly lower event-free survival (p = 0.001) than those with a lower level. Further Cox proportional-hazards regression analysis, including the traditional risk factors for cardiovascular disease, showed that serum FGF21 was an independent predictor of MACE occurrence. CONCLUSIONS: In patients with CAD at baseline, an elevated serum FGF21 level was associated with the development of a MACE in the future. PMID- 29462799 TI - MicroRNA-27a Suppresses Detrusor Fibrosis in Streptozotocin-Induced Diabetic Rats by Targeting PRKAA2 Through the TGF-beta1/Smad3 Signaling Pathway. AB - BACKGROUND/AIMS: We examined the effects of microRNA-27a (miR-27a) on detrusor fibrosis in streptozotocin (STZ)-induced diabetic rats. METHODS: Eighty healthy Sprague-Dawley (SD) rats were randomly allocated into control, diabetic, miR-27a mimics, mimics control, miR-27a inhibitors, inhibitors control, siRNA-PRKAA2 (siPRKAA2) and inhibitors + siPRKAA2 groups (the latter 7 groups were established as STZ-induced diabetic rat models and treated in different manners). Detrusor cell apoptosis in bladder tissues was determined through terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling assay (TUNEL) staining. Detrusor cells were assigned to the blank, miR-27a mimics, mimics control, miR-27a inhibitors, inhibitors control, siPRKAA2 and inhibitors + siPRKAA2 groups. Flow cytometry determined the cell cycle stage and apoptosis. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) and western blotting (WB) were used to assess the expression of miR-27a, PRKAA2, TGF beta1, Smad3, p-Smad3, fibronectin (FN), connective tissue growth (CTGF), and collagen-I (COL-I) in tissues and cells. RESULTS: Compared with the control group, the diabetic, miR-27a mimics, and siPRKAA2 groups showed reduced weight and PRKAA2 expression, but elevated blood glucose, serum creatinine (sCr), blood urea nitrogen (BUN), cell apoptosis, and expression of TGF-beta1, Smad3, FN, COL I, CTGF, and p-Smad3. The opposite trend was observed in the miR-27a inhibitors group. PRKAA2 is a target gene of miR-27a. Compared to the blank group, the miR 27a mimics and siPRKAA2 groups indicated markedly increased TGF-beta1, Smad3, FN, COL-I, CTGF and p-Smad3 expression; decreased PRKAA2 expression; and increased cell apoptosis. The miR-27a inhibitors group showed the opposite trend. CONCLUSION: These results indicate that miR-27a may contribute to detrusor fibrosis in STZ-induced diabetic rats by targeting PRKAA2 via the TGF-beta1/Smad3 signaling pathway.

PMID- 29462802 TI - Treatment of Chronic Immune Thrombocytopenic Purpura with Homeopathic Dilutions of Patient Blood. AB - BACKGROUND: Conventional or homeopathic treatment of chronic immune thrombocytopenic purpura (ITP) is often difficult. The use of homeopathic dilutions of patient blood (HPB) for immunomodulation has been described, which inspired us to try the method in an ITP case. CASE REPORT: A 2-year-old girl with chronic ITP was treated with homeopathic dilutions of her own capillary blood, given orally over 5 months. Immediately after treatment onset there was a rapid normalization of the thrombocyte counts. Within 6 weeks, they rose from 15,000/ul to 254,000/ul. After treatment stop, they decreased to 155,000/ul, increased again spontaneously to 270,000/ul and remained within normal range for over 3 years. CONCLUSIONS: Oral administration of homeopathic dilutions of capillary patient blood may possibly be an effective treatment in chronic ITP. If our results can be reproduced, this will revolutionize the treatment of ITP. PMID- 29462800 TI - Anti- Versus Pro-Inflammatory Metabololipidome Upon Cupping Treatment. AB - BACKGROUND/AIMS: This study aimed to explore the metabololipidome in mice upon cupping treatment. METHODS: A nude mouse model mimicking the cupping treatment in humans was established by administrating four cupping sets on the back skin for 15 minutes. UPLC-MS/ MS was performed to determine the PUFA metabolome in mice skin and blood before and after cupping treatment. The significantly changed lipids were administered in macrophages to assess the production of pro inflammatory cytokines IL-6 and TNF-alpha by ELISA. RESULTS: The anti inflammatory lipids, e.g. PGE1, 5,6-EET, 14,15-EET, 10S,17S-DiHDoHE, 17R-RvD1, RvD5 and 14S-HDoHE were significantly increased while pro-inflammatory lipids, e.g. 12-HETE and TXB2 were deceased in the skin or plasma post cupping treatment. Cupping treatment reversed the LPS-stimulated IL-6 and TNF-alpha expression in mouse peritoneal exudates. Moreover, 5,6-EET, PGE1 decreased the level of TNF alpha, while 5,6-EET, 5,6-DHET downregulated IL-6 production in macrophages. Importantly, 14,15-EET and 14S-HDoHE inhibited both IL-6 and TNF-alpha induced by lipopolysaccharide (LPS). 17-RvD1, RvD5 and PGE1 significantly reduced the LPS initiated TNF-alpha, while TXB2 and 12-HETE further upregulated the LPS-enhanced IL-6 and TNF-alpha expression in macrophages. CONCLUSION: Our results reveal the identities of anti-inflammatory versus pro-inflammatory metabolipidome and suggest the potential therapeutic mechanism of cupping treatment. PMID- 29462803 TI - Chromosome Painting in Tyrant Flycatchers Confirms a Set of Inversions Shared by Oscines and Suboscines (Aves, Passeriformes). AB - Tyrannidae is the largest family of Passeriformes in the Neotropical region. However, despite an interesting chromosomal diversity, there are only few cytogenetic studies of this family, and most of these are based on conventional cytogenetics. Hence, we analyzed here the chromosomal diversity and karyotypical evolution of this group by chromosome painting in 3 different species - Pitangus sulphuratus, Serpophaga subcristata, and Satrapa icterophrys - and make comparisons with previous data. In addition to chromosome painting with Gallus gallus (GGA) and Leucopternis albicollis (LAL) probes, karyotypes were analyzed by conventional staining, C-banding, and FISH with 18S rDNA and telomeric probes. Although this family is characterized by extensive chromosomal variation, we found similar karyotypes and diploid numbers ranging from 2n = 80 in P. sulphuratus to 2n = 82 in S. subcristata and S. icterophrys. Constitutive heterochromatin was located centromerically in all 3 species. Clusters of 18S rDNA were present in 1 pair of microchromosomes, except in S. subcristata, where 2 pairs of microchromosomes were labeled. No interstitial telomeric sequences were detected. GGA and LAL whole-chromosome probes revealed the occurrence of fissions and both paracentric and pericentric inversions commonly seen in other Passeriformes. In general terms, tyrants show the typical karyotype found in Passeriformes, suggesting that the observed rearrangements occurred before the division of the suborders Oscines and Suboscines. PMID- 29462804 TI - Angiotensin II Regulates Th1 T Cell Differentiation Through Angiotensin II Type 1 Receptor-PKA-Mediated Activation of Proteasome. AB - BACKGROUND/AIMS: Naive CD4+ T cells differentiate into T helper cells (Th1 and Th2) that play an essential role in the cardiovascular diseases. However, the molecular mechanism by which angiotensin II (Ang II) promotes Th1 differentiation remains unclear. The aim of this study was to determine whether the Ang II induced Th1 differentiation regulated by ubiquitin-proteasome system (UPS). METHODS: Jurkat cells were treated with Ang II (100 nM) in the presence or absence of different inhibitors. The gene mRNA levels were detected by real-time quantitative PCR analysis. The protein levels were measured by ELISA assay or Western blot analysis, respectively. RESULTS: Ang II treatment significantly induced a shift from Th0 to Th1 cell differentiation, which was markedly blocked by angiotensin II type 1 receptor (AT1R) inhibitor Losartan (LST). Moreover, Ang II significantly increased the activities and the expression of proteasome catalytic subunits (beta1, beta1i, beta2i and beta5i) in a dose- and time dependent manner. However, Ang II-induced proteasome activities were remarkably abrogated by LST and PKA inhibitor H-89. Mechanistically, Ang II-induced Th1 differentiation was at least in part through proteasome-mediated degradation of IkappaBalpha and MKP-1 and activation of STAT1 and NF-kappaB. CONCLUSIONS: This study for the first time demonstrates that Ang II activates AT1R-PKA-proteasome pathway, which promotes degradation of IkappaBalpha and MKP-1 and activation of STAT1 and NF-kappaB thereby leading to Th1 differentiation. Thus, inhibition of proteasome activation might be a potential therapeutic target for Th1-mediated diseases. PMID- 29462805 TI - Low-Intensity Pulsed Ultrasound Prevents the Oxidative Stress Induced Endothelial Mesenchymal Transition in Human Aortic Endothelial Cells. AB - BACKGROUND/AIMS: Endothelial-mesenchymal transition (EndMT) has been shown to take part in the generation and progression of diverse diseases, involving a series of changes leading to a loss of their endothelial characteristics and an acquirement of properties typical of mesenchymal cells. Low-intensity pulsed ultrasound (LIPUS) is a new therapeutic option that has been successfully used in fracture healing. However, whether LIPUS can inhibit oxidative stress-induced endothelial cell damages through inhibiting EndMT remained unknown. This study aimed to investigate the protective effects of LIPUS against oxidative stress induced endothelial cell damages and the underlying mechanisms. METHODS: EndMT was induced by H2O2 (100 um for seven days). Human aortic endothelial cells (HAECs) were exposed to H2O2 with or without LIPUS treatment for seven days. The expression of EndMT markers (CD31, VE-cadherin, FSP1 and alpha-SMA) were analyzed. The levels of total and phosphorylated PI3K and AKT proteins were detected by Western Blot analysis. Cell chemotaxis was determined by wound healing and transwell assay. RESULTS: LIPUS relieved EndMT by decreasing ROS accumulation and increasing activation of the PI3K signaling cascade. LIPUS alleviated the migration of EndMT-derived mesenchymal-like cells through reducing extracellular matrix (ECM) deposition that is associated with matrix metallopeptidase (MMP) proteolytic activity and collagen production. CONCLUSION: LIPUS produces cytoprotective effects against oxidative injuries to endothelial cells through suppressing the oxidative stress-induced EndMT, activating the PI3K/AKT pathway under oxidative stress, and limiting cell migration and excessive ECM deposition. PMID- 29462806 TI - HGF and BFGF Secretion by Human Adipose-Derived Stem Cells Improves Ovarian Function During Natural Aging via Activation of the SIRT1/FOXO1 Signaling Pathway. AB - BACKGROUND/AIMS: Human adipose-derived stem cells (hADSCs) are a potential therapeutic option for clinical applications because of their ability to produce cytokines and their capacity for trilineage differentiation. To date, few researchers have investigated the effects of hADSCs on natural ovarian aging (NOA). METHODS: An NOA mouse model and human ovarian granule cells (hGCs) collected from individuals with NOA were prepared to assess the therapeutic effects and illuminate the mechanism of hADSCs in curing NOA. Enzyme-linked immunosorbent assay was used to detect the serum levels of sex hormones and antioxidative enzymes. The proliferation rate and marker expression level of hGCs were measured by flow cytometry (FACS). Cytokines were measured by a protein antibody array methodology. Western blot assays were used to determine the protein expression levels of SIRT1 and FOXO1. RESULTS: Our results showed that hADSCs displayed therapeutic activity against ovarian function in an NOA mouse model, increasing the proliferation rate and marker expression level of hGCs. Furthermore, the yields of hADSC-secreted HGF and bFGF were higher than those of other growth factors. FACS showed that combination treatment with the growth factors HGF and bFGF more strongly promoted proliferation and inhibited apoptosis in hGCs than HGF or bFGF treatment alone. FACS and ELISA revealed that the combination treatment with both growth factors inhibited oxidative stress more forcefully than treatments with only one of these growth factors. In addition, protein assays demonstrated that combination treatment with both growth factors suppressed oxidative stress by up-regulating the expression of SIRT1 and FOXO1. CONCLUSION: These findings demonstrate for the first time the molecular cascade and related cell biology events involved in the mechanism by which HGF and bFGF derived from hADSCs improved ovarian function during natural aging via reduction of oxidative stress by activating the SIRT1/FOXO1 signaling pathway. PMID- 29462807 TI - The Return of Fear: Variation of the Serotonin Transporter Gene Predicts Outcome of a Highly Standardized Exposure-Based One-Session Fear Treatment. AB - BACKGROUND: Methodological problems of existing research, such as the application of unstandardized treatments in heterogeneous samples, has hampered clear conclusions about the extent and direction to which allelic variation of the serotonin transporter gene-linked polymorphic region (5- HTTLPR) is associated with a differential response to psychological treatment. The present study aimed to investigate the effects of the 5-HTTLPR genotype on treatment outcome under highly standardized environmental conditions. METHODS: We treated 222 medication free adults highly fearful of spiders, dental surgeries or blood, injuries and injections with a highly standardized exposure-based 1-session treatment and genotyped them for the 5-HTTLPR. Participants' subjective fear was assessed before, immediately after treatment and at 7 months of follow-up. RESULTS: There were no differences between 5-HTTLPR genotypes in treatment outcome effects at the immediate posttreatment assessment. However, we observed a highly significant genotype * treatment effect (p = 0.004) at the 7-month follow-up. Fear levels of homozygous S allele carriers differed from those heterozygous (p = 0.026) and homozygous (p = 0.012) for the L allele. Compared to posttreatment assessment, LL allele carriers exhibited a further fear decrease at the follow-up assessment. In contrast, SS allele carriers displayed a strong return of fear. CONCLUSIONS: Results suggest that genetic variation of the serotonin transporter is associated with differential stability of inhibitory learning processes, potentially reflecting heightened susceptibility for context-related processes that facilitate a return of fear in S allele carriers. If replicated, results suggest the 5-HTTLPR might represent a biomarker for the long-term outcome of brief exposure-based fear treatments and might inform genotype-based selection of psychotherapeutic interventions. PMID- 29462808 TI - Bronchial Carcinoid? Interventional Pulmonologist First! PMID- 29462809 TI - Liver Plays a Major Role in FGF-21 Mediated Glucose Homeostasis. AB - BACKGROUND/AIMS: The liver is a vital organ in vertebrates and has a wide range of functions, including glucose absorption, glycogen storage and glucose production. Fibroblast growth factor (FGF)-21 is a metabolic regulator that is primarily produced by the liver. In this paper, we studied the effect of FGF-21 on glucose metabolism in the liver. METHODS: The glucose uptake of cells was detected by 2-Deoxy-d-[3H] glucose; the synergy between insulin and FGF-21 was evaluated. The mRNA expression of GLUT1-4, G6Pase and PEPCK was detected by real time PCR. Glycogen synthesis was examined by the anthrone method. Blood samples to monitor glucose in db/db diabetic mice were obtained by tail snip. Glucose metabolism in the liver and adipose tissues was observed by fluorescence microscopy. RESULTS: In this study, FGF-21 stimulated glucose uptake by liver cells in both a dose and time-dependent manner, and at the same time, FGF-21 specifically stimulated GLUT1 expression in the liver cells. Furthermore, FGF-21 demonstrated a synergistic effect with insulin on glucose absorption, which is in accordance with enhanced GLUT-1 and -4 expression. Treatment with FGF-21 increased glycogen storage in liver cells. Consistent with in vitro results, FGF 21 lowered the plasma glucose level and stimulated GLUT1 expression and glycogen synthesis in db/db diabetic mice. Simultaneously, FGF-21 inhibited the gene expression of G6Pase and PEPCK. CONCLUSION: Our results suggest that FGF-21 clears up plasma glucose by stimulating glucose absorption in the liver of diabetic animals and decreases glucose release from the liver by inhibiting gluconeogenesis. Overall, these data indicate that the liver is an important target organ of FGF-21 to regulate glucose metabolism. PMID- 29462810 TI - Consumption of Amaranth Induces the Accumulation of the Antioxidant Protein Paraoxonase/Arylesterase 1 and Modulates Dipeptidyl Peptidase IV Activity in Plasma of Streptozotocin-Induced Hyperglycemic Rats. AB - BACKGROUND/AIM: Amaranth is a source of several bioactive compounds, among which peptides with inhibitory activity upon dipeptidyl peptidase IV (DPP-IV) have been reported. However, there is no information about the action of amaranth DPP-IV inhibitory peptides using in vivo models. The aim of this work was to evaluate the effect of amaranth consumption on plasma and kidney DPP-IV activity as well the changes in plasma proteome profile of streptozotocin (STZ)-induced hyperglycemic rats. METHODS: Rats were fed for 12 weeks with a diet containing 20% popped amaranth grain. Kidneys and blood samples were collected for lipid profile, DPP-IV activity and expression, and proteomic analysis. RESULTS: Total cholesterol and DPP-IV activity in plasma was increased in hyperglycemic rats, but this effect was reverted by amaranth consumption. Triacylglycerols were increased in the hyperglycemic group fed amaranth, and the highest levels of high density lipoproteins were also observed in this group. These data correlated with the accumulation of apolipoprotein A-II in plasma. Accumulation of the antioxidant protein paraoxonase/arylesterase 1 in STZ-induced hyperglycemic rats was observed when amaranth was supplied in the diet. CONCLUSION: This study provides new insights into the molecular mechanisms by which amaranth exerts its beneficial health action in a hyperglycemic state. PMID- 29462811 TI - Infraorbital Nerve Located Medially to Postoperative Maxillary Cysts: A Risk of Endonasal Surgery. AB - BACKGROUND/AIMS: This study aimed to examine variations in the location of the infraorbital nerve relative to postoperative maxillary cysts to assess the potential risk of nerve injury during endonasal marsupialization. METHODS: Coronal computed tomography images of 130 patients (162 sides) with postoperative maxillary cysts who visited our clinic between 2003 and 2014 were reviewed from the viewpoint of the anatomical relationship between the infraorbital nerves and cysts. RESULTS: The proportions of the six locations were as follows: upside 45.1% (n = 73), separate 13.0% (n = 21), medial 5.6% (n = 9), lateral 14.2% (n = 23), in-between 7.4% (n = 12), and unevaluable 14.8% (n = 24). The proportion of the cases with a potential risk of infraorbital nerve damage during endoscopic marsupialization, including medial, in-between, and unevaluable locations, was 27.8%. Retrospective chart review revealed that 2 patients with a postoperative maxillary cyst that were unevaluable complained of persistent postoperative hypoesthesia of the cheek. CONCLUSION: The anatomical relationship between the infraorbital nerve and postoperative maxillary cysts varied among patients, with approximately one-fourth of the patients being at risk of infraorbital nerve injury even during endoscopic procedures.

AB - INTRODUCTION: We aimed to clarify the survival rate without brain abnormalities (BA) after fetoscopic laser photoco-agulation (FLP) for monochorionic diamniotic twin gestations (MCDA) with selective intrauterine growth restriction (sIUGR) accompanied by abnormal umbilical artery (UA) Doppler waveforms and isolated oligohydramnios in the sIUGR twin. MATERIALS AND METHODS: This retrospective study included 52 cases that underwent FLP. The main outcome was survival rate without BA of the twins at age 28 days. BA was defined as severe intraventricular hemorrhage and periventricular leukomalacia on postnatal ultrasonography. RESULTS: Median gestational age at FLP was 20 (16-24) weeks. Ten cases were classified as type III based on Doppler for the UA. For all cases, including 20 cases of anterior placenta, FLP was completed without major intraoperative complications. Amnioinfusion was required in 49 cases for better fetoscopic visualization. Fetal loss occurred in 29 sIUGR twins and two larger twins, whereas one larger twin experienced neonatal death. Survival rates without BA were 44% (n = 23) for sIUGR twins and 94% (n = 49) for the larger twins. DISCUSSION: FLP for MCDA with sIUGR presenting with oligohydramnios in the sIUGR twin might be considered a prenatal treatment option. PMID- 29462813 TI - Hemostatic Efficacy and Safety of the Novel Medical Adhesive, MAR VIVO-107, in a Rabbit Liver Resection Model. AB - BACKGROUND: Topical hemostatic agents are useful when hepatic hemorrhage is difficult to control. The aim of this study was to evaluate the hemostatic efficacy and safety of a biodegradable polyurethane-based adhesive, MAR VIVO-107 (MAR), in comparison with a clinically used fibrin glue. METHODS: Thirty female New Zealand white rabbits were randomly assigned to 3 study groups as follows: MAR (n = 10), fibrin glue (n = 10), and saline groups (n = 10). After standardized partial liver resection was performed, each agent was immediately applied to the wound area. Bleeding time until hemostasis and blood loss were recorded. After 7 days, body weight, hematology parameters, and serum levels of aspartate aminotransferase, alanine aminotransferase, and lactate dehydrogenase were measured. Simultaneously, the severity of intra-abdominal adhesion was evaluated. RESULTS: The mean bleeding time in the MAR (38 +/- 10 s) and fibrin glue groups (65 +/- 17 s) was significantly shorter than that in the saline group (186 +/- 12 s). Similarly, the mean blood loss in the MAR (9 +/- 3 g) and fibrin glue groups (9 +/- 3 g) was significantly less than that in the saline group (23 +/- 4 g). No significant differences in bleeding time and blood loss were found between the MAR and fibrin glue groups. The postoperative survival rate was 100% in all the groups. Body weight as well as hematological and serum biochemical values on day 7 were within the small and physiological range when compared with the preoperative baseline values, and significant differences were not detected among the MAR, fibrin glue, and saline groups. The severities of adhesion were similar between the 3 groups. CONCLUSION: Our data demonstrated that MAR was not inferior to fibrin glue in terms of hemostatic efficacy and safety.

PMID- 29462815 TI - A Trend in Sudden Sensorineural Hearing Loss: Data from a Population-Based Study. AB - This is the first study reporting on the incidence and clinical aspects of sudden sensorineural hearing loss (SSNHL) in South Korea. Using Health Insurance Review and Assessment Service data from 2011 to 2015, the monthly incidence of unilateral SSNHL and incidence according to patients' sex, age, and month of diagnosis were investigated. The monthly incidence of unilateral SSNHL increased over the 5-year study period, with a mean annual incidence of 17.76 cases/ 100,000 of the population. The incidence increased with age, with most patients presenting in their 60s. There was a slight female preponderance, with a male-to female ratio of 1: 1.35. Most new patients were diagnosed in October, and the fewest in January. In conclusion, this large-scale study indicates that unilateral SSNHL has a higher incidence among the elderly, women, and in autumn (i.e., along with colder weather).

PMID- 29462817 TI - The Interaction of N-Acetylcysteine and Serum Transferrin Promotes Bacterial Biofilm Formation. AB - BACKGROUND/AIMS: N-acetylcysteine (NAC) is a novel and promising agent with activity against bacterial biofilms. Human serum also inhibits biofilm formation by some bacteria. We tested whether the combination of NAC and human serum offers greater anti-biofilm activity than either agent alone. METHODS: Microtiter plate assays and confocal laser scanning microscopy were used to evaluate bacterial biofilm formation in the presence of NAC and human serum. qPCR was used to examine expression of selected biofilm-associated genes. Extracellular matrix (ECM) was observed by transmission electron microscopy. The antioxidants GSH or ascorbic acid were used to replace NAC, and human transferrin, lactoferrin, or bovine serum albumin were used to replace serum proteins in biofilm formation assays. A rat central venous catheter model was developed to evaluate the effect of NAC on biofilm formation in vivo. RESULTS: NAC and serum together increased biofilm formation by seven different bacterial strains. In Staphylococcus aureus, expression of genes for some global regulators and for genes in the ica-dependent pathway increased markedly. In Pseudomonas aeruginosa, transcription of las, the PQS quorum sensing (QS) systems, and the two-component system GacS/GacA increased significantly. ECM production by S. aureus and P. aeruginosa was also enhanced. The potentiation of biofilm formation is due mainly to interaction between NAC and transferrin. Intravenous administration of NAC increased colonization by S. aureus and P. aeruginosa on implanted catheters. CONCLUSIONS: NAC used intravenously or in the presence of blood increases bacterial biofilm formation rather than inhibits it. PMID- 29462818 TI - Effects of MicroRNA-206 on Osteosarcoma Cell Proliferation, Apoptosis, Migration and Invasion by Targeting ANXA2 Through the AKT Signaling Pathway. AB - BACKGROUND/AIMS: This study aimed to investigate the mechanism by which microRNA 206 (miR-206) affects the proliferation, apoptosis, migration and invasion of osteosarcoma (OS) cells by targeting ANXA2 via the AKT signaling pathway. METHODS: A total of 132 OS tissues and 120 osteochondroma tissues were examined in this study. The targeting relationship between miR-206 and ANXA2 was verified with a dual-luciferase reporter assay. The miR-206 expression and ANXA2, AKT, PARP, FASN, Survivin, Bax, Mcl-1 and Bcl-1 mRNA and protein expression in the above two groups were examined by qRT-PCR and western blotting. The cultured OS cells were divided into 6 groups: a blank group, negative control (NC) group, miR 206 mimic group, miR-206 inhibitor group, si-ANXA2 group and miR-206 inhibitor + si-ANXA2 group. Cell cycle and apoptosis were assessed by flow cytometry, cell migration was examined with a wound-healing assay, and cell invasion was assessed with a Transwell assay. Pearson correlation analysis was used to determine the correlation between ANXA2 mRNA expression and miR-206 expression in OS. RESULTS: OS tissues exhibited increased mRNA and protein expression of ANXA2, AKT, PARP, FASN, Survivin, Mcl-1 and Bcl-2; decreased miR-206 expression; and decreased Bax mRNA and protein expression. ANXA2 mRNA expression was strongly negatively correlated with miR-206 expression in OS. ANXA2 was found to be a miR-206 target gene. In the miR-206 mimic group and the si-ANXA2 group, the mRNA and protein expression of ANXA2, AKT, PARP, FASN, Survivin, Mcl-1 and Bcl-1 decreased markedly, cell proliferation was inhibited, apoptosis was promoted, higher cell growth in G1 phase and decreased growth in S phase was detected, and decreased cell migration and invasion were observed compared with those in the blank group. CONCLUSION: The current results demonstrate that miR-206 overexpression inhibits OS cell proliferation, migration and invasion and promotes apoptosis through targeting ANXA2 by blocking the AKT signaling pathway.

PMID- 29462821 TI - The Topography of Stuttering in Cantonese. AB - OBJECTIVE: This is the first study to investigate the behavioral nature (topography) of stuttering in Cantonese. Cantonese, a Sino-Tibetan language, is both tonal and syllable-timed. Previous studies of stuttering topography have mainly been in Western languages, which are mainly stress-timed. METHODS: Conversational speech samples were collected from 24 native Cantonese-speaking adults who stuttered. Six consecutive stuttering moments from each participant were analyzed using the Lidcombe behavioral data language (LBDL). A complexity analysis based on the LBDL was developed to indicate the proportion of multiple behavior stuttering moments for each participant. RESULTS: There was no significant difference in the frequency of the 7 LBDL behaviors. Almost half the stuttering moments across participants were reported as complex, containing more than 1 stuttering behavior, and stuttering complexity correlated significantly with stuttering severity. CONCLUSIONS: These preliminary findings require replication because of their important theoretical and clinical implications. Differences in topography across languages have the potential to contribute to our understanding of the nature of stuttering. Clinically, the recognition of such differences may assist practitioners in identifying stuttering, for example when screening for early stuttering. The LBDL complexity score developed in this study has the potential to be used in other languages. PMID- 29462822 TI - Vocal Fry and Vowel Height in Simulated Room Acoustics. AB - PURPOSE: The purpose of this study was to investigate the influence of room acoustics in the relationship between vowel height and vocal fry. METHODS: This was a cross-sectional study. Participants (college students, n = 40) read the first six sentences of "The Rainbow Passage" under nine simulated room acoustic conditions. Using two words with low vowels (act, pot) and two words with high vowels (shape, strikes) preceding a voiceless stop, the presence/absence of vocal fry was assessed using an automatic detection script. Generalized estimation equations were used to investigate the relationship between percentage of vocal fry, vowel height, and room acoustics. RESULTS: The percentage of vocal fry was significantly higher for the low-height vowels compared with the high-height vowels (beta = 1.21; standard er ror = 0.35), and for pink background noise present (beta = 0.89; standard error = 0.35) compared with the condition without artificial noise added. CONCLUSION: The results of this study indicate that young college students are more likely to produce fry phonation when producing low height vowels under pink background noise condition compared with no noise conditions and high-height vowels. This result is of special interest for voice clinicians when designing therapy plans and vocal assessment protocols with fry like components. PMID- 29462823 TI - Early Psychological Counseling for the Prevention of Posttraumatic Stress Induced by Acute Coronary Syndrome: The MI-SPRINT Randomized Controlled Trial. AB - BACKGROUND: Acute coronary syndrome (ACS)-induced posttraumatic stress disorder (PTSD) and clinically significant PTSD symptoms (PTSS) are found in 4 and 12% of patients, respectively. We hypothesized that trauma-focused counseling prevents the incidence of ACS-induced PTSS. METHODS: Within 48 h of hospital admission, 190 patients with high distress during ACS were randomized to a single-session intervention of either trauma-focused counseling or an active control intervention targeting the general role of stress in patients with heart disease. Blind interviewer-rated PTSS (primary outcome) and additional health outcomes were assessed at 3 months of follow-up. Trial results about prevalence were compared with data from previous studies on the natural incidence of ACS-induced PTSS/PTSD. RESULTS: Intention-to-treat analyses revealed no difference in interviewer-rated PTSS between trauma-focused counseling (mean, 11.33; 95% Cl, 9.23-13.43) and stress counseling (9.88; 7.36-12.40; p = 0.40), depressive symptoms (6.01, 4.98-7.03, vs. 4.71, 3.65-5.77; p = 0.08), global psychological distress (5.15, 4.07-6.23, vs. 3.80, 2.60-5.00; p = 0.11), and the risk for cardiovascular-related hospitalization/all-cause mortality (OR, 0.67; 95% CI, 0.37-1.23). Self-rated PTSS indicated less beneficial effects with trauma-focused (6.54; 4.95-8.14) versus stress counseling (3.74; 2.39-5.08; p = 0.017). The completer analysis (154 cases) confirmed these findings. The prevalence rates of interviewer-rated PTSD (0.5%, 1/190) and self-rated PTSS were in this trial much lower than in meta-analyses and observation studies from the same cardiology department. CONCLUSIONS: Benefits were not seen for trauma-focused counseling when compared with an active control intervention. Nonetheless, in distressed ACS patients, individual, single-session, early psychological counseling shows potential as a means to prevent posttraumatic responses, but trauma-focused early treatments should probably be avoided. PMID- 29462824 TI - The "Auto-sliding Graft" Aortic Wrapping Technique. AB - We describe the "auto-sliding graft" technique, a different anastomotic option for reconstructive prosthetic procedures on the ascending aorta especially in patients at risk of circulatory arrest with mild aortic dilatation. This simple technique provides not only an important hemostatic reinforcement for the distal aortic graft anastomosis but also a protective effect on the native ascending aorta beyond the suture line. PMID- 29462825 TI - Golgi Fragmentation in Human Patients with Chronic Atrial Fibrillation: A New Aspect of Remodeling. AB - BACKGROUND: Atrial fibrillation (AF) is the most common chronic arrhythmia in elderly people and is accompanied by remodeling processes. While much is known about changes in ionic channels and in extracellular matrix, less is known about possible changes of intracellular structures. OBJECTIVE: We wanted to investigate, whether AF may also affect the structure of the Golgi apparatus and the microtubular network. METHODS: One-hundred fifty-three cardiac surgery patients were investigated [n = 24 in sinus rhythm (SR) and n = 129 with chronic AF of >1 year duration]. Tissue samples of the left atrial free wall were examined immunohistochemically. Golgi apparatus was detected by GM130 and its phosphorylated isoform. Furthermore, we investigated the length of the microtubules by alpha-tubulin staining. We also measured stathmin (phospho-S37), which is known to induce microtubule depolymerization. In addition, we investigated the cyclin-dependent kinase cdk5-activation, a typical stimulus for Golgi fragmentation, by measuring membrane-associated cdk5. RESULTS: We found significant fragmentation of the Golgi apparatus in AF together with a reduced fragment size. Significant more fragments of the Golgi were found lateral to the nucleus in AF, while the Golgi in SR was located more to the polar side of the nucleus, that is, in the longitudinal axis of the cell. This was accompanied by a significant reduction of the number of tubulin strands longer than 10 um. These changes did not go along with an activation of stathmin, but with an increase in membrane association of cdk5. CONCLUSIONS: The present data may show that AF associated remodeling also involves intracellular remodeling of the Golgi microtubular apparatus. PMID- 29462826 TI - Graft-Sparing Strategy for Thoracic Prosthetic Graft Infection. AB - OBJECTIVE: Thoracic prosthetic graft infection is a rare but serious complication with no standard management. We reported our surgical experience on graft-sparing strategy for thoracic prosthetic graft infection. METHODS: This study included patients who underwent graft-sparing surgery for thoracic prosthetic graft infection at Matsubara Tokushukai Hospital in Japan from January 2000 to October 2017. RESULTS: There were 17 patients included in the analyses, with a mean age at surgery of 71.0 +/- 10.5 years; 11 were men. In-hospital mortality was observed in five patients (29.4%). CONCLUSIONS: Graft-sparing surgery for thoracic prosthetic graft infection is an alternative option particularly for early graft infection after hemiarch replacement. PMID- 29462827 TI - Which is the Best Minimal Invasive Approach for the Treatment of Spontaneous Pneumothorax? Uniport, Two, or Three Ports: A Prospective Randomized Trail. AB - OBJECTIVE: Video-assisted thoracoscopic surgery (VATS) has become the standard treatment method for primary spontaneous pneumothorax. Concerns about lesser pain and better cosmesis led to the evolution of uniportal access. This study prospectively compared the results of the uniportal, two-port, and three-port thoracoscopic surgery. MATERIAL AND METHODS: One hundred and thirty-five patients were randomized into three groups according to the port numbers. The groups were compared regarding the operation time, hospital stay, amount of drainage, area of pleurectomy, complications, recurrences, and pain scores. RESULTS: Except for the amount of drainage (p = 0.03), no factors were found to be statistically significant. The overall recurrence rate was 5%. Although the first and second week pain scores were not statistically significant, the single-incision group patients had significantly less pain at 4, 24, and 72 hours (p < 0.05). CONCLUSION: The study indicated that uniportal VATS approach is less painful and has better cosmetic results, besides it is as efficient as two- or three-port VATS approach. PMID- 29462828 TI - Computer-Aided Surgical Simulation in Head and Neck Reconstruction: A Cost Comparison among Traditional, In-House, and Commercial Options. AB - BACKGROUND: Computer-aided surgical simulation (CASS) has redefined surgery, improved precision and reduced the reliance on intraoperative trial-and-error manipulations. CASS is provided by third-party services; however, it may be cost effective for some hospitals to develop in-house programs. This study provides the first cost analysis comparison among traditional (no CASS), commercial CASS, and in-house CASS for head and neck reconstruction. METHODS: The costs of three dimensional (3D) pre-operative planning for mandibular and maxillary reconstructions were obtained from an in-house CASS program at our large tertiary care hospital in Northern Virginia, as well as a commercial provider (Synthes, Paoli, PA). A cost comparison was performed among these modalities and extrapolated in-house CASS costs were derived. The calculations were based on estimated CASS use with cost structures similar to our institution and sunk costs were amortized over 10 years. RESULTS: Average operating room time was estimated at 10 hours, with an average of 2 hours saved with CASS. The hourly cost to the hospital for the operating room (including anesthesia and other ancillary costs) was estimated at $4,614/hour. Per case, traditional cases were $46,140, commercial CASS cases were $40,951, and in-house CASS cases were $38,212. Annual in-house CASS costs were $39,590. CONCLUSIONS: CASS reduced operating room time, likely due to improved efficiency and accuracy. Our data demonstrate that hospitals with similar cost structure as ours, performing greater than 27 cases of 3D head and neck reconstructions per year can see a financial benefit from developing an in-house CASS program. PMID- 29462829 TI - [Evaluation of velopharyngeal closing pressure during trumpet play with high resolution manometry]. AB - OBJECTIVE: In about one-third of brass instrumentalists, there are stress-related insufficiencies of velopharyngeal closure (VPC), i. e. the intraoral pressure exceeds the barrier formed by the VPC. Here, it was the aim to measure the VPC closing pressure while playing a trumpet and to evaluate the influence of a 30 minute stress sequence on the muscular activities in the VPC. MATERIAL AND METHODS: Sample: 6 healthy volunteers; task: to play the sound h1 for 5 seconds with 85 dB(A) and with 100 dB(A). METHODOLOGY: High-resolution manometry (HRM). SAMPLING: t0: measurement without warm up phase t1 after 30 min trumpet play; practice phase with predefined pieces of music. VARIABLES: mean (pmit), minimum (pmin) and maximum pressure (pmax) in the VPA at t0 and t1. STATISTICS: testing for normal distribution, t-test. RESULTS: All measured pressures in the VPC decreased from t0 to t1 for tones produced at 85 dB(A). For 100 dB(A) tones only the pmin decreased significantly. The pressures in the VPA were higher at 100 dB(A) tones overall compared to 85 dB(A) tones, significant differences were found for pmin and pmax at t0. CONCLUSION: Tones played at louder volumes require a stronger muscular contraction in the VPC. The lower VPC pressure after the exercise phase (t1) can either result from a physiological muscular adaptation to the pressure level necessary for a sufficient VPC or already be a sign of muscular fatigue. These findings may be important to assess the work ability of wind instrumentalists by HRM. As shown for the phonation, the VPC pressure profile for the trumpet play can also be described with a three-phase model consisting of an initiation, a stable phase and a termination. PMID- 29462830 TI - [Quo Vadis Data Linkage in Germany? An Initial Inventory]. AB - In recent years, linking different data sources, also called data linkage or record linkage, to address scientific questions, is being increasingly used in Germany. However, there are very few published reports and new projects develop the necessary tools independently of each other. Therefore, a team of researchers joined together to exchange their experiences on data linkage and to give suggestions on how linkage could be done for scientists, reviewers as well as members of data privacy boards and ethics committees. It is the aim of this article to assist future projects that want to link German data on an individual level. In addition to the legal framework conditions (data privacy), also examples of types of data linkage, their fields of application und potential pitfalls as well as the methods of preventing them will be described in an application-oriented fashion. PMID- 29462831 TI - ? PMID- 29462832 TI - [Pulmonary Medicine and its Institutions During National Socialism]. AB - When the National Socialists came to power in 1933, a complete paradigm shift took place in the health policy under the principle "Public interest ahead of self-interest". In the early years there was an intense discussion about whether tuberculosis (TB) is more caused by heredity or by infection. Finally, the arguments of leading TB specialists were accepted that TB is predominantly an infectious disease. In 1939, the year Germany started World War II, TB mortality was at its lowest, with only a few countries having lower rates. TB mortality increased in all areas during the war, both in the civilian population and in the Wehrmacht, as well as in prisoners of war, foreign forced laborers and concentration camps. Incapable TB patients were considered biological and social "ballast". They were worthless for the "national community" and had to be socially excluded. Thus one could refuse them the "marriage loan" introduced in the summer 1933, forbid starting from 1935 also the marriage. From 1938 on, TB patients with open TB, who showed themselves unreasonable, could be compulsorily isolated as "asocial" by public health physicians - mostly pulmonary specialists. There, under prison conditions and with limited food, most patients fell victim to TB in a short time. Especially inhuman was the handling of prisoners in the concentration camps, where the disease was very common. Thousands of people were killed prematurely through deliberate neglect, starvation, abuse for medical experiments, or simply murdered. TB mortality increased by 160 - 240 % compared to pre-war levels. With the support of the victorious Allied powers, the TB control system was restructured and the institutions such as DGP and DZK were re established. In the following years, the TB situation improved slowly, in the FRG initially slightly faster than in the GDR. PMID- 29462833 TI - Multilevel moderated mediation model with ordinal outcome. AB - Although increasingly complex models have been proposed in mediation literature, there is no model nor software that incorporates the multiple possible generalizations of the simple mediation model jointly. We propose a flexible moderated mediation model allowing for (1) a hierarchical structure of clustered data, (2) more and possibly correlated mediators, and (3) an ordinal outcome. The motivating data set is obtained from a European study in nursing research. Patients' willingness to recommend their treating hospital was recorded in an ordinal way. The research question is whether such recommendation directly depends on system-level features in the organization of nursing care, or whether these associations are mediated by 2 measurements of nursing care left undone and possibly moderated by nurse education. We have developed a Bayesian approach and accompanying program that takes all the above generalizations into account. PMID- 29462834 TI - Cost-effectiveness of a chronic disease management model for cirrhosis: Analysis of a randomized controlled trial. AB - BACKGROUND AND AIMS: In this follow-up study to a randomized controlled trial of a chronic disease management (CDM) model in cirrhosis, our aim was to assess the relative cost-effectiveness of this model compared with usual care during the 12 month study period, using incremental costs per death avoided as the primary outcome. METHODS: Mean differences in hospitalization costs, deaths avoided, and change in Chronic Liver Disease Questionnaire (CLDQ) total scores were presented with 95% non-parametric bootstrapped confidence intervals. Results were also presented using a cost-effectiveness plane (CEP) and cost-effectiveness acceptability curve. RESULTS: The CDM intervention was more expensive, by 18 521 AUD per participant, but more effective (% of deaths at 12 months: 10% vs 15% and 0.67 units increase per patient in CLDQ total scores). The resultant incremental cost-effectiveness ratios were 370 425 AUD per death avoided (95% confidence interval: -14 564 AUD to 2 059 373 AUD) and 27 547 AUD per unit improvement in the CLDQ total score (95% CI: 7455 AUD to 143 874 AUD). The CEPs demonstrated some uncertainty around cost-effectiveness. The cost-effectiveness acceptability curves demonstrated that at willingness to pay values of 400 000 AUD per additional death avoided and 40 000 AUD per unit improvement in the CLDQ, there was at least a 70% probability of CDM being more cost-effective than usual care. At 24 months, CDM was much more effective (12% less deaths but now also cheaper by 985 AUD per patient). CONCLUSIONS: The analysis of data from a randomized controlled trial suggests that the CDM intervention used is likely to be cost effective, relative to usual care, due to fewer patient deaths. PMID- 29462835 TI - Controlling the type I error rate in two-stage sequential adaptive designs when testing for average bioequivalence. AB - In a 2*2 crossover trial for establishing average bioequivalence (ABE) of a generic agent and a currently marketed drug, the recommended approach to hypothesis testing is the two one-sided test (TOST) procedure, which depends, among other things, on the estimated within-subject variability. The power of this procedure, and therefore the sample size required to achieve a minimum power, depends on having a good estimate of this variability. When there is uncertainty, it is advisable to plan the design in two stages, with an interim sample size reestimation after the first stage, using an interim estimate of the within-subject variability. One method and 3 variations of doing this were proposed by Potvin et al. Using simulation, the operating characteristics, including the empirical type I error rate, of the 4 variations (called Methods A, B, C, and D) were assessed by Potvin et al and Methods B and C were recommended. However, none of these 4 variations formally controls the type I error rate of falsely claiming ABE, even though the amount of inflation produced by Method C was considered acceptable. A major disadvantage of assessing type I error rate inflation using simulation is that unless all possible scenarios for the intended design and analysis are investigated, it is impossible to be sure that the type I error rate is controlled. Here, we propose an alternative, principled method of sample size reestimation that is guaranteed to control the type I error rate at any given significance level. This method uses a new version of the inverse normal combination of p-values test, in conjunction with standard group sequential techniques, that is more robust to large deviations in initial assumptions regarding the variability of the pharmacokinetic endpoints. The sample size reestimation step is based on significance levels and power requirements that are conditional on the first-stage results. This necessitates a discussion and exploitation of the peculiar properties of the power curve of the TOST testing procedure. We illustrate our approach with an example based on a real ABE study and compare the operating characteristics of our proposed method with those of Method B of Povin et al. PMID- 29462836 TI - Current practice for genetic counselling by nurses: An integrative review. AB - AIM: To examine current practice of genetic counselling by nurses. BACKGROUND: Recent debate argues that genetic counselling is a specialist advanced practice role, whilst others argue it is the role of all nurses. Current evidence is required to determine if genetic counselling could be included in all nurses' scope of practice. DESIGN: Integrative literature review. DATA SOURCES: A search of electronic databases (CINHAL, Medline, PubMed, Scopus), and reference lists published between January 2012 and March 2017, was undertaken. REVIEW METHODS: Studies were critically appraised for methodological quality using the Critical Appraisal Skills Programme. Data from each study were extracted and categorized according to their primary findings. RESULTS: The inclusion criteria were met in 10 studies. Main findings were identified: role of genetic counselling, current knowledge, need for further education, and client satisfaction with nurse genetic counsellors. CONCLUSION: This paper concludes that some nurses do engage in genetic counselling, but how they engage is not consistent, nor is there consensus about what should be the scope of practice. Further investigation into credentialing, role recognition support and education for nurse genetic counselling are strongly recommended. As nurses are widely available, nurses can make a significant contribution to supporting those affected by genetic problems. PMID- 29462837 TI - Reduced arterial vasodilatation in response to hypoxia impairs cerebral and peripheral oxygen delivery in hypertensive men. AB - KEY POINTS: Hypoxaemia evokes a repertoire of homeostatic adjustments that maintain oxygen supply to organs and tissues including the brain and skeletal muscles. Because hypertensive patients have impaired endothelial-dependent vasodilatation and an increased sympathetic response to arterial oxygen desaturation, we investigated whether hypertension impairs isocapnic hypoxia induced cerebral and skeletal muscle hyperaemia to an extent that limits oxygen supply. In middle-aged hypertensive men, vertebral and femoral artery blood flow do not increase in response to isocapnic hypoxia, limiting brain and peripheral hyperaemia and oxygen supply. Increased chemoreflex-induced sympathetic activation impairs skeletal muscle perfusion and oxygen supply, whereas an attenuation of local vasodilatory signalling in the posterior cerebrovasculature reduced brain hyperperfusion of hypertensive middle-aged men in response to isocapnic hypoxia. ABSTRACT: The present study investigated whether hypertension impairs isocapnic hypoxia (IH)-induced cerebral and skeletal muscle hyperaemia to an extent that limits oxygen supply. Oxygen saturation (oxymetry), mean arterial pressure (photoplethysmography) and muscle sympathetic nerve activity (MSNA; microneugraphy), as well as femoral artery (FA), internal carotid artery and vertebral artery (VA) blood flow (BF; Doppler ultrasound), were quantified in nine normotensive (NT) (aged 40 +/- 11 years, systolic pressure 119 +/- 7 mmHg and diastolic pressure 73 +/- 6 mmHg) and nine hypertensive men (HT) (aged 44 +/- 12 years, systolic pressure 152 +/- 11 mmHg and diastolic pressure 90 +/- 9 mmHg) during 5 min of normoxia (21% O2 ) and IH (10% O2 ). Total cerebral blood flow (tCBF), brain (CDO2 ) and leg (LDO2 ) oxygen delivery were estimated. IH provoked similar oxygen desaturation without changing mean arterial pressure. Internal carotid artery perfusion increased in both groups during IH. However, VA and FA BF only increased in NT. Thus, IH-induced increase in tCBF was smaller in HT. CDO2 only increased in NT and LDO2 decreased in HT. Furthermore, IH evoked a greater increase in HT MSNA. Changes in MSNA were inversely related to FA BF, LDO2 and end-tidal oxygen tension. In conclusion, hypertension disturbs regional and total cerebrovascular and peripheral responses to IH and consequently limits oxygen supply to the brain and skeletal muscle. Although increased chemoreflex induced sympathetic activation may explain impaired peripheral perfusion, attenuated vasodilatory signalling in the posterior cerebrovasculature appears to be responsible for the small increase in tCBF when HT were exposed to IH. PMID- 29462838 TI - Sequential parallel comparison design with binary and time-to-event outcomes. AB - Sequential parallel comparison design (SPCD) has been proposed to increase the likelihood of success of clinical trials especially trials with possibly high placebo effect. Sequential parallel comparison design is conducted with 2 stages. Participants are randomized between active therapy and placebo in stage 1. Then, stage 1 placebo nonresponders are rerandomized between active therapy and placebo. Data from the 2 stages are pooled to yield a single P value. We consider SPCD with binary and with time-to-event outcomes. For time-to-event outcomes, response is defined as a favorable event prior to the end of follow-up for a given stage of SPCD. We show that for these cases, the usual test statistics from stages 1 and 2 are asymptotically normal and uncorrelated under the null hypothesis, leading to a straightforward combined testing procedure. In addition, we show that the estimators of the treatment effects from the 2 stages are asymptotically normal and uncorrelated under the null and alternative hypothesis, yielding confidence interval procedures with correct coverage. Simulations and real data analysis demonstrate the utility of the binary and time-to-event SPCD.

AB - To estimate direct and indirect effects of an exposure on an outcome from observed data, strong assumptions about unconfoundedness are required. Since these assumptions cannot be tested using the observed data, a mediation analysis should always be accompanied by a sensitivity analysis of the resulting estimates. In this article, we propose a sensitivity analysis method for parametric estimation of direct and indirect effects when the exposure, mediator, and outcome are all binary. The sensitivity parameters consist of the correlations between the error terms of the exposure, mediator, and outcome models. These correlations are incorporated into the estimation of the model parameters and identification sets are then obtained for the direct and indirect effects for a range of plausible correlation values. We take the sampling variability into account through the construction of uncertainty intervals. The proposed method is able to assess sensitivity to both mediator-outcome confounding and confounding involving the exposure. To illustrate the method, we apply it to a mediation study based on the data from the Swedish Stroke Register (Riksstroke). An R package that implements the proposed method is available.

AB - Juvenile dermatomyositis (JDM) is a rare autoimmune disease that may lead to serious complications, even to death. We develop a 2-state Markov regression model in a Bayesian framework to characterise disease progression in JDM over time and gain a better understanding of the factors influencing disease risk. The transition probabilities between disease and remission state (and vice versa) are a function of time-homogeneous and time-varying covariates. These latter types of covariates are introduced in the model through a latent health state function, which describes patient-specific health over time and accounts for variability among patients. We assume a nonparametric prior based on the Dirichlet process to model the health state function and the baseline transition intensities between disease and remission state and vice versa. The Dirichlet process induces a clustering of the patients in homogeneous risk groups. To highlight clinical variables that most affect the transition probabilities, we perform variable selection using spike and slab prior distributions. Posterior inference is performed through Markov chain Monte Carlo methods. Data were made available from the UK JDM Cohort and Biomarker Study and Repository, hosted at the UCL Institute of Child Health.

AB - The importance of emotional support for dying persons and their families has been well established, yet we know less about how care workers understand emotional processes related to death and dying, or how these understandings are connected to care practices and emotional labour at the end of life. The aim of this study was to explore how healthcare workers interpret and respond to emotional needs of dying persons and their families. Qualitative data were collected between 2013 and 2014 through in-depth, in-person interviews with 14 nurses and 12 healthcare aides in one Western Canadian city. Transcripts were analysed using an inductive, interpretive thematic coding approach and the analytic lens of emotional labour. Dominant interpretive frames of a "good death" informed participants' emotionally supportive practice. This included guiding patients and families to "open up" about their emotions to activate the grief process. There was concern that incomplete grieving would result in anger being directed towards care staff. The goal of promoting emotional sharing informed the work of "caring about." Although palliative philosophies opened up moral and professional space for "caring about" in the context of organisational norms which often discouraged these practices, the tension between the two, and the lack of time for this work, may encourage surface expressions rather than authentic emotional care. PMID- 29462842 TI - Hyperinflation of bronchi in vitro impairs bronchodilation to simulated breathing and increases sensitivity to contractile activation. AB - BACKGROUND AND OBJECTIVE: Lung hyperinflation and reduced bronchodilation to deep inspiration (DI) are features of chronic obstructive pulmonary disease (COPD). Hyperinflation might impair the ability of a DI to stretch airway smooth muscle (ASM), as the bronchi operate at a stiff region of the pressure-volume curve. METHODS: Bronchial segments from pig lungs were mounted in an organ bath and equilibrated at either 5 cm H2 O (control) or 20 cm H2 O (hyperinflated) transmural pressure (Ptm ). Cumulative dose-response curves to acetylcholine (ACh) were performed to determine maximal response (Emax ) and sensitivity under static conditions (fixed Ptm ) or during simulated breathing (Delta10 cm H2 O Ptm at 0.25 Hz). The effect of hyperinflation on ASM contraction was further examined in bronchial rings contracted at a short ASM length (reference length, Lref ) or stretched by an additional 30% (length 1.3 times the Lref , 1.3Lref ). RESULTS: Oscillatory loads halved Emax from 61.0 +/- 3.8 to 29.7 +/- 4.4 cm H2 O (P < 0.0001) in control bronchial segments, but only from 40.0 +/- 2.5 to 31.2 +/- 2.4 cm H2 O (P < 0.05) in hyperinflated segments. The percentage reduction in active pressure with oscillation was less in hyperinflated compared with control segments (P < 0.01). Sensitivity was not altered by oscillation in either hyperinflated or control segments; however, hyperinflated segments were more sensitive (P < 0.05). The effect of inflation on sensitivity was confirmed using bronchial rings where stretched rings were more sensitive than unstretched rings (P < 0.01). CONCLUSION: Hyperinflated bronchi exhibit reduced bronchodilation to breathing and increased sensitivity to bronchoconstrictor stimuli. Findings suggest that hyperinflation may directly alter airway function by reducing the protective effects of DI and initiating contraction at low doses of contractile stimuli. PMID- 29462843 TI - Three-dimensional photography for the evaluation of facial profiles in obstructive sleep apnoea. AB - BACKGROUND AND OBJECTIVE: Craniofacial structure is an important determinant of obstructive sleep apnoea (OSA) syndrome risk. Three-dimensional stereo photogrammetry (3dMD) is a novel technique which allows quantification of the craniofacial profile. This study compares the facial images of OSA patients captured by 3dMD to three-dimensional computed tomography (3-D CT) and two dimensional (2-D) digital photogrammetry. Measurements were correlated with indices of OSA severity. METHODS: Thirty-eight patients diagnosed with OSA were included, and digital photogrammetry, 3dMD and 3-D CT were performed. Distances, areas, angles and volumes from the images captured by three methods were analysed. RESULTS: Almost all measurements captured by 3dMD showed strong agreement with 3-D CT measurements. Results from 2-D digital photogrammetry showed poor agreement with 3-D CT. Mandibular width, neck perimeter size and maxillary volume measurements correlated well with the severity of OSA using all three imaging methods. Mandibular length, facial width, binocular width, neck width, cranial base triangle area, cranial base area 1 and middle cranial fossa volume correlated well with OSA severity using 3dMD and 3-D CT, but not with 2-D digital photogrammetry. CONCLUSION: 3dMD provided accurate craniofacial measurements of OSA patients, which were highly concordant with those obtained by CT, while avoiding the radiation associated with CT. PMID- 29462844 TI - How can we improve the performance of Model for End-Stage Liver Disease sodium score in patients with hepatitis B virus-related decompensated liver cirrhosis commencing antiviral treatment? AB - BACKGROUND AND AIM: We aimed to develop a more efficient prognostic model to predict 1-year mortality in patients with hepatitis B virus-related decompensated cirrhosis beginning antiviral treatment. METHODS: Using Cox regression analysis, survival analyses were performed on 554 patients with decompensated cirrhosis who were followed up from the start of nucleos(t)ide analogue antiviral treatment. RESULTS: At baseline, ascites and hepatic encephalopathy were found in 78.0% and 18.1% of patients, respectively. Eighty-six events (77 deaths and 9 emergency liver transplants) occurred within the first year of treatment. Severity of ascites, presence of hepatic encephalopathy, and the Model for End-Stage Liver Disease (MELD)-sodium (MELDNa) score were independent risk factors for 1-year mortality. The new prognostic model (the revised MELDNa) constructed by adding ascites and encephalopathy to the MELDNa score significantly improved the area under the receiver operating characteristics curve for predicting 1-year events at baseline compared with the Child-Turcotte-Pugh system, MELD and MELDNa models, and Fontana index (0.905 vs 0.867, 0.843, 0.871, and 0.815, respectively; P < 0.05). Furthermore, repetitive application of revised MELDNa at 0, 1, 2, 3, and 6 months of treatment could predict 81.4% (70/86) of 1-year events, which was significantly (P < 0.05) higher than the sensitivity of the Child-Turcotte-Pugh system (68.6%), MELD (70.9%) and MELDNa (68.6%) scores, and Fontana index (64.0%), achieving similar specificities of ~96%. CONCLUSIONS: Ascites and encephalopathy should be considered together with the MELDNa score when predicting short-term mortality and planning liver transplant in patients with decompensated hepatitis B virus-related cirrhosis starting antiviral treatment. PMID- 29462845 TI - Comparison of the microbial community structure between inflamed and non-inflamed sites in patients with ulcerative colitis. AB - BACKGROUND AND AIM: The gut microbiota is suggested to play an important role in the pathogenesis of ulcerative colitis (UC). However, interindividual and spatial variations hamper the identification of UC-related changes. We thus investigated paired mucosa-associated microbiota obtained from both inflamed and non-inflamed sites of UC patients and corresponding sites of non-inflammatory bowel disease (IBD) controls. METHODS: Mucosal biopsies of both inflamed and non-inflamed sites were obtained from 14 patients with active UC of the left-sided or proctitis type. Paired mucosal biopsies of the corresponding sites were obtained from 14 non-IBD controls. The microbial community structure was investigated using 16S ribosomal RNA gene sequences, followed by data analysis using qiime and LEfSe softwares. RESULTS: Microbial alpha diversity in both inflamed and non-inflamed sites was significantly lower in UC patients compared with non-IBD controls. There were more microbes of the genus Cloacibacterium and the Tissierellaceae family, and there were less microbes of the genus Neisseria at the inflamed site when compared with the non-inflamed site in UC patients. Decreased abundance of the genera Prevotella, Eubacterium, Neisseria, Leptotrichia, Bilophila, Desulfovibrio, and Butyricimonas was evident at the inflamed site of UC patients compared with the corresponding site of non-IBD controls. Among these taxa, the genera Prevotella and Butyricimonas were also less abundant at the non-inflamed site of UC patients compared with the corresponding site in non-IBD controls. CONCLUSIONS: Mucosal microbial dysbiosis occurs at both inflamed and non-inflamed sites in UC patients. The taxa showing altered abundance in UC patients might mediate colonic inflammation. PMID- 29462846 TI - Authenticity, acceptability, and feasibility of a hybrid gynecology station for the Papanicolaou test as part of a clinical skills examination in Korea. AB - PURPOSE: The objective of this study was to evaluate the authenticity, acceptability, and feasibility of a hybrid station that combined a standardized patient encounter and a simulated Papanicolaou test. METHODS: We introduced a hybrid station in the routine clinical skills examination (CSE) for 335 third year medical students at 4 universities in Korea from December 1 to December 3, 2014. After the tests, we conducted an anonymous survey on the authenticity, acceptability, and feasibility of the hybrid station. RESULTS: A total of 334 medical students and 17 professors completed the survey. A majority of the students (71.6%) and professors (82.4%) agreed that the hybrid station was more authentic than the standard CSE. Over 60 percent of the students and professors responded that the station was acceptable for assessing the students' competence. Most of the students (75.2%) and professors (82.4%) assessed the required tasks as being feasible after reading the instructions. CONCLUSION: Our results showed that the hybrid CSE station was a highly authentic, acceptable, and feasible way to assess medical students' performance. PMID- 29462847 TI - Use of the ultrasound-based total malignancy score in the management of thyroid nodules. AB - PURPOSE: The purpose of this study was to validate the role of the total malignancy score (TMS) in identifying thyroid nodules suspicious for malignancy through the sum of their ultrasound features. METHODS: The local ethical committee approved this prospective observational study. We examined 231 nodules in 231 consecutive patients (164 females and 67 males; age range, 20 to 87 years; median age, 59 years; interquartile range, 48 to 70 years) who underwent ultrasound followed by fine-needle aspiration cytology (FNAC). The nodules were further classified using the TMS, which considers ultrasound features (number, echogenicity, structure, halo, margins, Doppler signal, calcifications, and growth), and the Bethesda System for Reporting Thyroid Cytopathology (TBSRTC), which considers cytological features. Patients with non-negative nodules (TBSRTC categories III to VI) underwent histological analysis, repeated FNAC, or 2 years of regular ultrasound follow-up. The associations between the final diagnosis, each of the ultrasound features, and the TMS were estimated using the chi-square test, the Mann-Whitney U test, and multivariate logistic regression. A receiver operating characteristic (ROC) curve was used to evaluate the diagnostic accuracy of the TMS. RESULTS: On ultrasound, 47% of the nodules (108 of 231) had a TMS >3, 18% (42 of 231) had a TMS of 3, and 35% (81 of 231) had a TMS >3. The FNAC results of 85% of the nodules (196 of 231) were benign, while 15% (35 of 231) had non-negative results. Hypoechogenicity, solid structure, the presence of microcalcifications, and the number of nodules were independent predictors of the final diagnosis, and the diagnostic accuracy of the TMS was good (area under the ROC curve, 0.82). CONCLUSION: The TMS system is simple to use, reliable, easily reproducible, and closely reflects malignancy risk. Based on our results, FNAC could be limited to nodules with a TMS >=3 without missing any cases of carcinoma. PMID- 29462848 TI - Anti-Diabetic Effect of Cotreatment with Quercetin and Resveratrol in Streptozotocin-Induced Diabetic Rats. AB - Quercetin and resveratrol are known to have beneficial effects on the diabetes and diabetic complication, however, the effects of combined treatment of these compounds on diabetes are not fully revealed. Therefore, the present study was designed to investigate the combined antidiabetic action of quercetin (QE) and resveratrol (RS) in streptozotocin (STZ)-induced diabetic rats. To test the effects of co-treated with these compounds on diabetes, serum glucose, insulin, lipid profiles, oxidative stress biomarkers, and ions were determined. Additionally, the activities of hepatic glucose metabolic enzymes and histological analyses of pancreatic tissues were evaluated. 50 male Sprague Dawley rats were divided into five groups; normal control, 50 mg/kg STZ-induced diabetic, and three (30 mg/kg QE, 10 mg/kg RS, and combined) compound-treated diabetic groups. The elevated serum blood glucose levels, insulin levels, and dyslipidemia in diabetic rats were significantly improved by QE, RS, and combined treatments. Oxidative stress and tissue injury biomarkers were dramatically inhibited by these compounds. They also shown to improve the hematological parameters which were shown to the hyperlactatemia and ketoacidosis as main causes of diabetic complications. The compounds treatment maintained the activities of hepatic glucose metabolic enzymes and structure of pancreatic beta cells from the diabetes, and it is noteworthy that cotreatment with QE and RS showed the most preventive effect on the diabetic rats. Therefore, our study suggests that cotreatment with QE and RS has beneficial effects against diabetes. We further suggest that cotreatment with QE and RS has the potential for use as an alternative therapeutic strategy for diabetes. PMID- 29462849 TI - Synthetic 3',4'-Dihydroxyflavone Exerts Anti-Neuroinflammatory Effects in BV2 Microglia and a Mouse Model. AB - Neuroinflammation is an immune response within the central nervous system against various proinflammatory stimuli. Abnormal activation of this response contributes to neurodegenerative diseases such as Parkinson disease, Alzheimer's disease, and Huntington disease. Therefore, pharmacologic modulation of abnormal neuroinflammation is thought to be a promising approach to amelioration of neurodegenerative diseases. In this study, we evaluated the synthetic flavone derivative 3',4'-dihydroxyflavone, investigating its anti-neuroinflammatory activity in BV2 microglial cells and in a mouse model. In BV2 microglial cells, 3',4'-dihydroxyflavone successfully inhibited production of chemokines such as nitric oxide and prostaglandin E2 and proinflammatory cytokines such as tumor necrosis factor alpha, interleukin 1 beta, and interleukin 6 in BV2 microglia. It also inhibited phosphorylation of mitogen-activated protein kinase (MAPK) and nuclear factor (NF)-kappaB activation. This indicates that the anti-inflammatory activities of 3',4'-dihydroxyflavone might be related to suppression of the proinflammatory MAPK and NF-kappaB signaling pathways. Similar anti neuroinflammatory activities of the compound were observed in the mouse model. These findings suggest that 3',4'-dihydroxyflavone is a potential drug candidate for the treatment of microglia-related neuroinflammatory diseases. PMID- 29462850 TI - Effect of Atomic Charges on Octanol-Water Partition Coefficient Using Alchemical Free Energy Calculation. AB - The octanol-water partition coefficient (logPow) is an important index for measuring solubility, membrane permeability, and bioavailability in the drug discovery field. In this paper, the logPow values of 58 compounds were predicted by alchemical free energy calculation using molecular dynamics simulation. In free energy calculations, the atomic charges of the compounds are always fixed. However, they must be recalculated for each solvent. Therefore, three different sets of atomic charges were tested using quantum chemical calculations, taking into account vacuum, octanol, and water environments. The calculated atomic charges in the different environments do not necessarily influence the correlation between calculated and experimentally measured ?Gwater values. The largest correlation coefficient values of the solvation free energy in water and octanol were 0.93 and 0.90, respectively. On the other hand, the correlation coefficient of logPow values calculated from free energies, the largest of which was 0.92, was sensitive to the combination of the solvation free energies calculated from the calculated atomic charges. These results reveal that the solvent assumed in the atomic charge calculation is an important factor determining the accuracy of predicted logPow values. PMID- 29462851 TI - Alleviating Pancreatic Cancer-Associated Pain Using Endoscopic Ultrasound-Guided Neurolysis. AB - The most common symptom in patients with advanced pancreatic cancer is abdominal pain. This has traditionally been treated with nonsteroidal anti-inflammatory drugs and opioid analgesics. However, these treatments result in inadequate pain control or drug-related adverse effects in some patients. An alternative pain relief modality is celiac plexus neurolysis, in which the celiac plexus is chemically ablated. This procedure was performed percutaneously or intraoperatively until 1996, when endoscopic ultrasound (EUS)-guided celiac plexus neurolysis was first described. In this transgastric anterior approach, a neurolytic agent is injected around the celiac trunk under EUS guidance. The procedure gained popularity as a minimally invasive approach and is currently widely used to treat pancreatic cancer-associated pain. We focus on two relatively new techniques of EUS-guided neurolysis: EUS-guided celiac ganglia neurolysis and EUS-guided broad plexus neurolysis, which have been developed to improve efficacy. Although the techniques are safe and effective in general, some serious adverse events including ischemic and infectious complications have been reported as the procedure has gained widespread popularity. We summarize reported clinical outcomes of EUS-guided neurolysis in pancreatic cancer (from the PubMed and Embase databases) with a goal of providing information useful in developing strategies for pancreatic cancer-associated pain alleviation. PMID- 29462852 TI - Comparison of Structural and Functional Properties of Starches from the Rhizome and Bulbil of Chinese Yam. AB - Chinese yam is an important edible starch plant and widely cultivated in China. Its rhizome and bulbil are starch storage tissues below and above ground, respectively. In this paper, starches were isolated from the rhizome and bulbil of Chinese yam, and their structural and functional properties were compared. Both starches had an oval shape with an eccentric hilum and a CA-type crystalline structure. Their short-range ordered structure and lamellar structure had no significant difference. However, the rhizome starch had a significantly bigger granule size and lower amylose content than the bulbil starch. The swelling power and water solubility were significantly lower in the rhizome starch than in the bulbil starch. The onset and peak gelatinization temperatures were significantly higher in the rhizome starch than in the bulbil starch. The rhizome starch had a significantly higher breakdown viscosity and a lower setback viscosity than the bulbil starch. The thermal stability was lower in the rhizome starch than in the bulbil starch. The rhizome starch had a significantly lower resistance to hydrolysis and in vitro digestion than the bulbil starch. The above results provide important information for the utilization of rhizome and bulbil starches of Chinese yam. PMID- 29462854 TI - Chemical Composition of Pyroligneous Acid Obtained from Eucalyptus GG100 Clone. AB - The present study aimed to characterize the chemical composition of pyroligneous acid (PA) obtained from slow pyrolysis of the clone GG100 of Eucalyptus urophylla * Eucalyptus grandis. The efficiency of extraction of organic compounds by using different solvents-dichloromethane (DCM), diethyl ether (DE) and ethyl acetate (EA)-was evaluated. Wood discs were collected and carbonized at a heating rate of 1.25 degrees C/min until 450 degrees C. Pyrolysis gases were trapped and condensed, yielding a crude liquid product (CLP), which was refined to obtain pure PA. Then liquid-liquid extraction was carried out. Each extracted fraction was analyzed by GC-MS and the chemical compounds were identified. Experimental results showed that a larger number of chemical compounds could be extracted by using DCM and EA in comparison to diethyl ether DE. A total number of 93 compounds were identified, with phenolic compounds being the major group, followed by aldehydes and ketones, furans, pyrans and esters. Higher contents of guaiacol, phenol, cresols and furfural seem to explain the antibacterial and antifungal activity shown by PA, as reported previously in the literature. Experimental data indicated that the organic phase extracted from GG100 PA consists of a mixture of compounds similar to liquid smokes regularly used in the food industry. PMID- 29462855 TI - Enhanced Automated Guidance System for Horizontal Auger Boring Based on Image Processing. AB - Horizontal auger boring (HAB) is a widely used trenchless technology for the high accuracy installation of gravity or pressure pipelines on line and grade. Differing from other pipeline installations, HAB requires a more precise and automated guidance system for use in a practical project. This paper proposes an economic and enhanced automated optical guidance system, based on optimization research of light-emitting diode (LED) light target and five automated image processing bore-path deviation algorithms. An LED light target was optimized for many qualities, including light color, filter plate color, luminous intensity, and LED layout. The image preprocessing algorithm, direction location algorithm, angle measurement algorithm, deflection detection algorithm, and auto-focus algorithm, compiled in MATLAB, are used to automate image processing for deflection computing and judging. After multiple indoor experiments, this guidance system is applied in a project of hot water pipeline installation, with accuracy controlled within 2 mm in 48-m distance, providing accurate line and grade controls and verifying the feasibility and reliability of the guidance system. PMID- 29462853 TI - Organ-Specific Metabolic Shifts of Flavonoids in Scutellaria baicalensis at Different Growth and Development Stages. AB - Scutellaria baicalensis Georgi is a traditional Chinese herbal medicine mainly containing flavonoids that contribute to its bioactivities. In this study, the distributions and dynamic changes of flavonoid levels in various organs of S. baicalensis at different development stages were investigated by UHPLC-QTOF-MS/MS and HPLC-DAD methods. The results indicated that the metabolic profiles of S. baicalensis changed with growth and development. During the initial germination stage, the seeds mainly contained flavonols. With growth, the main kinds of flavonoids in S. baicalensis changed from flavonols to flavanones and flavones. The results also revealed that the accumulation of flavonoids in S. baicalensis is organ-specific. The flavones without 4'-OH groups mainly accumulate in the root and the flavanones mainly accumulate in aerial organs. Dynamic accumulation analysis showed that the main flavonoids in the root of S. baicalensis accumulated rapidly before the full-bloom stage, then changed to a small extent. The results suggested the proper harvest time for the aerial parts was at the initial stage of reproductive growth and the flower buds should be collected before flowering. This study deepening the knowledge of S. baicalensis should provide valuable information for guiding the scientific cultivation of this plant and the development and utilization of S. baicalensis. PMID- 29462856 TI - Morphological Pathways of Mitochondrial Division. AB - Mitochondrial fission is essential for distributing cellular energy throughout cells and for isolating damaged regions of the organelle that are targeted for degradation. Excessive fission is associated with the progression of cell death as well. Therefore, this multistep process is tightly regulated and several physiologic cues directly impact mitochondrial division. The double membrane structure of mitochondria complicates this process, and protein factors that drive membrane scission need to coordinate the separation of both the outer and inner mitochondrial membranes. In this review, we discuss studies that characterize distinct morphological changes associated with mitochondrial division. Specifically, coordinated partitioning and pinching of mitochondria have been identified as alternative mechanisms associated with fission. Additionally, we highlight the major protein constituents that drive mitochondrial fission and the role of connections with the endoplasmic reticulum in establishing sites of membrane division. Collectively, we review decades of research that worked to define the molecular framework of mitochondrial fission. Ongoing studies will continue to sort through the complex network of interactions that drive this critical event. PMID- 29462857 TI - Analysis Method for Laterally Loaded Pile Groups Using an Advanced Modeling of Reinforced Concrete Sections. AB - A Boundary Element Method (BEM) approach was developed for the analysis of pile groups. The proposed method includes: the non-linear behavior of the soil by a hyperbolic modulus reduction curve; the non-linear response of reinforced concrete pile sections, also taking into account the influence of tension stiffening; the influence of suction by increasing the stiffness of shallow portions of soil and modeled using the Modified Kovacs model; pile group shadowing effect, modeled using an approach similar to that proposed in the Strain Wedge Model for pile groups analyses. The proposed BEM method saves computational effort compared to more sophisticated codes such as VERSAT-P3D, PLAXIS 3D and FLAC-3D, and provides reliable results using input data from a standard site investigation. The reliability of this method was verified by comparing results from data from full scale and centrifuge tests on single piles and pile groups. A comparison is presented between measured and computed data on a laterally loaded fixed-head pile group composed by reinforced concrete bored piles. The results of the proposed method are shown to be in good agreement with those obtained in situ. PMID- 29462858 TI - Highly Efficient Intracellular Protein Delivery by Cationic Polyethyleneimine Modified Gelatin Nanoparticles. AB - Intracellular protein delivery may provide a safe and non-genome integrated strategy for targeting abnormal or specific cells for applications in cell reprogramming therapy. Thus, highly efficient intracellular functional protein delivery would be beneficial for protein drug discovery. In this study, we generated a cationic polyethyleneimine (PEI)-modified gelatin nanoparticle and evaluated its intracellular protein delivery ability in vitro and in vivo. The experimental results showed that the PEI-modified gelatin nanoparticle had a zeta potential of approximately +60 mV and the particle size was approximately 135 nm. The particle was stable at different biological pH values and temperatures and high protein loading efficiency was observed. The fluorescent image results revealed that large numbers of particles were taken up into the mammalian cells and escaped from the endosomes into the cytoplasm. In a mouse C26 cell-xenograft cancer model, particles accumulated in cancer cells. In conclusion, the PEI modified gelatin particle may provide a biodegradable and highly efficient protein delivery system for use in regenerative medicine and cancer therapy. PMID- 29462859 TI - Physical Health Care for People with Severe Mental Illness: the Attitudes, Practices, and Training Needs of Nurses in Three Asian Countries. AB - People with severe mental illness (SMI) have considerable unmet physical health needs and an increased risk of early mortality. This cross-sectional survey utilized the Physical Health Attitude Scale (PHASe) to examine the attitudes, practices, and training needs of nurses towards physical health care of people with SMI in three Asian countries (Hong Kong, Japan, Qatar). Cross-country differences were explored and linear regression was used to investigate if nurses' attitudes and confidence were associated with their level of involvement in physical health care. A total of 481 questionnaires were returned. Hong Kong nurses were less involved in physical health care than those from Japan and Qatar. Nurses' attitudes and confidence were significant predictors of their participation in managing physical health. Compared with western countries, more nurses in this study felt that mental illness was a barrier to improving physical health. Three-quarters reported that they needed additional training in promoting cardiometabolic health. The perceived need for additional training in physical health care was held by Mental Health Nurses (MHN) irrespective of their type of nursing registration and nationality. Nurse educators and service providers should reconsider the physical health care training requirements of nurses working in mental health settings in order to improve the physical health of people with SMI. PMID- 29462860 TI - Work-Family Conflict, Perceived Organizational Support and Professional Commitment: A Mediation Mechanism for Chinese Project Professionals. AB - Projects are characterized by long working hours, complex tasks and being a kind of temporary organization. As such, work-family conflict is particularly prominent for project employees. This research examined whether and how work family conflict affects professional commitment among Chinese project professionals. Research hypotheses were developed to explore the relationship between work-family conflict, professional commitment to the project and the mediating effects of perceived organizational support. Data were collected from 327 project managers or professionals working in construction enterprises in China; data were analyzed using structural equation modeling, applying the bootstrapping method. Results showed that there were three dimensions of work family conflict: time-based conflict, strain-based conflict and behavior-based conflict. There were two dimensions of perceived organizational support: emotional support and instrumental support. The study also tested the negative effect of work-family conflict on professional commitment and the positive effect of perceived organizational support on professional commitment. Specifically, time-based conflict and emotional support had positive effects on professional commitment. Perceived organizational support had a total mediating effect between work-family conflict and professional commitment. The strain-based conflict dimension of work-family conflict had negative impacts on professional commitment through perceived emotional support and instrumental support. Overall, our findings extend a better understanding of work-family conflict and professional commitment in the project setting and verify the importance of social support in balancing work and family and improving employee mobility. PMID- 29462861 TI - Evaluating the Impacts of Health, Social Network and Capital on Craft Efficiency and Productivity: A Case Study of Construction Workers in China. AB - The construction industry has been recognized, for many years, as among those having a high likelihood of accidents, injuries and occupational illnesses. Such risks of construction workers can lead to low productivity and social problems. As a result, construction workers' well-being should be highly addressed to improve construction workers' efficiency and productivity. Meanwhile, the social support from a social network and capital (SNC) of construction workers has been considered as an effective approach to promote construction workers' physical and mental health (P&M health), as well as their work efficiency and productivity. Based on a comprehensive literature review, a conceptual model, which aims to improve construction workers' efficiency and productivity from the perspective of health and SNC, was proposed. A questionnaire survey was conducted to investigate the construction workers' health, SNC and work efficiency and productivity in Nanjing, China. A structural equation model (SEM) was employed to test the three hypothetical relationships among construction workers' P&M health, SNC and work efficiency and productivity. The results indicated that the direct impacts from construction workers' P&M health on work efficiency and productivity were more significant than that from the SNC. In addition, the construction workers' social capital and the network can indirectly influence the work efficiency and productivity by affecting the construction workers' P&M health. Therefore, strategies for enhancing construction workers' efficiency and productivity were proposed. Furthermore, many useable suggestions can be drawn from the research findings from the perspective of a government. The identified indicators and relationships would contribute to the construction work efficiency and productivity assessment and health management from the perspective of the construction workers. PMID- 29462862 TI - Evaluation of a Computer-Tailored Healthy Ageing Intervention to Promote Physical Activity among Single Older Adults with a Chronic Disease. AB - This study explores the effectiveness of the Active Plus65 intervention designed to stimulate physical activity among single older adults with a chronic physical impairment. A quasi-experimental pre-test post-test study was performed. The intervention group (n = 411; mean age = 76.75; SD = 7.75) was assessed at baseline, three months, and six months. Data of comparable older adults who completed the original Active Plus intervention served as reference group (n = 87; mean age = 74.36; SD = 6.26). Multilevel regression analyses were applied: outcome measures were weekly minutes of moderate to vigorous physical activity (MVPA) and days per week with at least 30 minutes of MVPA. Although Active Plus65 did not outperform the original intervention, in itself Active Plus65 effectuated a significant increase in the weekly minutes of MVPA (B = 208.26; p < 0.001; Effect Size (ES) = 0.45) and in the days per week with sufficient MVPA (B = 1.20; p < 0.001; ES = 0.61) after three months. After six months, it effectuated a significant increase in the days per week with sufficient MVPA (B = 0.67; p = 0.001; ES = 0.34) but not for the weekly minutes of MVPA (p = 0.745). As Active Plus65 increased MVPA at three months with a higher ES than average interventions for this vulnerable target group, it potentially makes an interesting intervention. Further development should focus on long-term maintenance of effects. PMID- 29462863 TI - Effects of Vacation Rental Websites on the Concentration of Tourists-Potential Environmental Impacts. An Application to the Balearic Islands in Spain. AB - The concentration of tourists at certain times of the year can damage sensitive environments. The use of peer-to-peer vacation rental websites has increased greatly during the last decade. This system could either reduce seasonality in touristic destinations where the tourist activity takes place throughout the year at a lower price or on the contrary, it could increase the number of visitors at certain times of the year even more. This paper intends to analyze the effect that these platforms have on tourism seasonality in order to calculate if they help reduce or increase the pressure on the destinations. To do so, the Gini Index has been applied to one of the main touristic spots in Europe, the Balearic Islands in Spain. The conclusion is that this type of accommodation has aggravated the problem, generating a greater concentration of tourists and a higher pressure on the resources of the islands. PMID- 29462864 TI - Semi-Preparative Separation of 10 Caffeoylquinic Acid Derivatives Using High Speed Counter-Current Chromatogaphy Combined with Semi-Preparative HPLC from the Roots of Burdock (Arctium lappa L.). AB - Burdock roots are healthy dietary supplements and a kind of famous traditional Chinese medicine, which contains large amounts of caffeoylquinic acid derivatives. However, little research has been reported on the preparative separation of these compounds from burdock roots. In the present study, a combinative method of HSCCC and semi-preparative HPLC was developed for the semi preparative separation of caffeoylquinic acid derivatives from the burdock roots. The ethyl acetate extract of burdock roots was first fractionated by MCI macroporous resin chromatography and give three fractions (Fr. 1-3) from the elution of 40% methanol. Then, these three fractions (120 mg) were separately subjected to HSCCC for purification with the solvent system composed of petroleum ether-ethyl acetate-methanol-water at different volume ratios, and the mixtures were further purified by semi-preparative HPLC. As a result, a total of eight known caffeoylquinic acid derivatives including 3-O-caffeoylquinic acid (32.7 mg, 95.7%), 1,5-O- dicaffeoylquinic acid (4.3 mg, 97.2%), 3-O-caffeoylquinic acid methyl ester (12.1 mg, 93.2%), 1,3-O-dicaffeoylquinic acid (42.9 mg, 91.1%), 1,5 O-dicaffeoyl-3-O-(4-maloyl)-quinic acid (4.3 mg, 84.5%), 4,5-O-dicaffeoylquinic acid (5.3 mg, 95.5%), 1,5-O-dicaffeoyl-3-O-succinylquinic acid (8.7 mg, 93.4%), and 1,5-O-dicaffeoyl-4-O-succinylquinic acid (1.7 mg, 91.8%), and two new compounds were obtained. The new compounds were 1,4-O-dicaffeoyl-3-succinyl methyl ester quinic acid (14.6 mg, 96.1%) and 1,5-O-dicaffeoyl-3-O-succinyl methyl ester quinic acid (3.1 mg, 92.6%), respectively. The research indicated that the combination of HSCCC and semi-preparative HPLC is a highly efficient approach for preparative separation of the instability and bioactive caffeoylquinic acid derivatives from natural products. PMID- 29462865 TI - A Novel Method of Autonomous Inspection for Transmission Line based on Cable Inspection Robot LiDAR Data. AB - With the growth of the national economy, there is increasing demand for electricity, which forces transmission line corridors to become structurally complicated and extend to complex environments (e.g., mountains, forests). It is a great challenge to inspect transmission line in these regions. To address these difficulties, a novel method of autonomous inspection for transmission line is proposed based on cable inspection robot (CIR) LiDAR data, which mainly includes two steps: preliminary inspection and autonomous inspection. In preliminary inspection, the position and orientation system (POS) data is used for original point cloud dividing, ground point filtering, and structured partition. A hierarchical classification strategy is established to identify the classes and positions of the abnormal points. In autonomous inspection, CIR can autonomously reach the specified points through inspection planning. These inspection targets are imaged with PTZ (pan, tilt, zoom) cameras by coordinate transformation. The feasibility and effectiveness of the proposed method are verified by test site experiments and actual line experiments, respectively. The proposed method greatly reduces manpower and improves inspection accuracy, providing a theoretical basis for intelligent inspection of transmission lines in the future. PMID- 29462867 TI - On-Site Detection of Aflatoxin B1 in Grains by a Palm-Sized Surface Plasmon Resonance Sensor. AB - Aflatoxins (AFs) are highly toxic compounds that can cause both acute and chronic toxicity in humans. Aflatoxin B1 (AFB1) is considered the most toxic of AFs. Therefore, the rapid and on-site detection of AFB1 is critical for food safety management. Here, we report the on-site detection of AFB1 in grains by a portable surface plasmon resonance (SPR) sensor. For the detection of AFB1, the surface of an SPR Au chip was sequentially modified by cysteine-protein G, AFB1 antibody, and bovine serum albumin (BSA). Then, the sample solution and AFB1-BSA conjugate were flowed onto the Au chip in serial order. In the absence of AFB1, the SPR response greatly increased due to the binding of AFB1-BSA on the Au chip. In the presence of AFB1, the SPR response showed little change because the small AFB1 molecule binds on the Au chip instead of the large AFB1-BSA molecule. By using this portable SPR-based competitive immunoassay, the sensor showed low limits of detection (2.51 ppb) and quantification (16.32 ppb). Furthermore, we successfully detected AFB1 in rice, peanut, and almond samples, which suggests that the proposed sensing method can potentially be applied to the on-site monitoring of mycotoxins in food. PMID- 29462866 TI - Traumatic Brain Injury, Sleep Disorders, and Psychiatric Disorders: An Underrecognized Relationship. AB - Traumatic brain injury (TBI) is commonplace among pediatric patients and has a complex, but intimate relationship with psychiatric disease and disordered sleep. Understanding the factors that influence the risk for the development of TBI in pediatrics is a critical component of beginning to address the consequences of TBI. Features that may increase risk for experiencing TBI sometimes overlap with factors that influence the development of post-concussive syndrome (PCS) and recovery course. Post-concussive syndrome includes physical, psychological, cognitive and sleep-wake dysfunction. The comorbid presence of sleep-wake dysfunction and psychiatric symptoms can lead to a more protracted recovery and deleterious outcomes. Therefore, a multidisciplinary evaluation following TBI is necessary. Treatment is generally symptom specific and mainly based on adult studies. Further research is necessary to enhance diagnostic and therapeutic approaches, as well as improve the understanding of contributing pathophysiology for the shared development of psychiatric disease and sleep-wake dysfunction following TBI. PMID- 29462868 TI - Inhibition of Cytochrome P450 Activities by Extracts of Hyptis verticillata Jacq.: Assessment for Potential HERB-Drug Interactions. AB - Understanding the potential for adverse drug reactions (ADRs), from herb-drug interactions, is a key aspect of medicinal plant safety, with particular relevance for public health in countries where medicinal plant use is highly prevalent. We undertook an in-depth assessment of extracts of Hyptis verticillata Jacq., via its impact on activities of key cytochrome P450 (CYP) enzymes (CYPs 1A1, 1A2, 1B1, 3A4 and 2D6), its antioxidant properties (determined by DPPH assays) and chemical characterisation (using LC-MS). The dried plant aqueous extract demonstrated potent inhibition of the activities of CYPs 1A1 (7.6 ug/mL), 1A2 (1.9 ug/mL), 1B1 (9.4 ug/mL) and 3A4 (6.8 ug/mL). Further analysis of other crude extracts demonstrated potent inhibition of CYP1A2 activity for a dried plant ethanol extract (1.5 ug/mL), fresh plant ethanol extract (3.9 ug/mL), and moderate activity for a fresh plant aqueous extract (27.8 ug/mL). All four extracts demonstrated strong antioxidant activity, compared to the positive control (ascorbic acid, 1.3 ug/mL), with the dried plant ethanol extract being the most potent (1.6 ug/mL). Analysis of the dried plant aqueous extract confirmed the identity of seven phytochemicals, five lignans and two triterpenes. Individual screening of these phytochemicals against the activity of CYP1A2 identified yatein as a moderate inhibitor (71.9 MUM), likely to contribute to the plant extract's potent bioactivity. Further analysis on the impact of this plant on key drug metabolizing enzymes in vivo appears warranted for likely ADRs, as well as furthering development as a potential chemopreventive agent. PMID- 29462869 TI - Modulation of VEGF-A Alternative Splicing as a Novel Treatment in Chronic Kidney Disease. AB - Vascular endothelial growth factor A (VEGF-A) is a prominent pro-angiogenic and pro-permeability factor in the kidney. Alternative splicing of the terminal exon of VEGF-A through the use of an alternative 3' splice site gives rise to a functionally different family of isoforms, termed VEGF-Axxxb, known to have anti angiogenic and anti-permeability properties. Dysregulation of the VEGF-Axxx/VEGF Axxxb isoform balance has recently been reported in several kidney pathologies, including diabetic nephropathy (DN) and Denys-Drash syndrome. Using mouse models of kidney disease where the VEGF-A isoform balance is disrupted, several reports have shown that VEGF-A165b treatment/over-expression in the kidney is therapeutically beneficial. Furthermore, inhibition of certain splice factor kinases involved in the regulation of VEGF-A terminal exon splicing has provided some mechanistic insight into how VEGF-A splicing could be regulated in the kidney. This review highlights the importance of further investigation into the novel area of VEGF-A splicing in chronic kidney disease pathogenesis and how future studies may allow for the development of splicing-modifying therapeutic drugs. PMID- 29462870 TI - Responsive Polydiacetylene Vesicles for Biosensing Microorganisms. AB - Polydiacetylene (PDA) inserted in films or in vesicles has received increasing attention due to its property to undergo a blue-to-red colorimetric transition along with a change from non-fluorescent to fluorescent upon application of various stimuli. In this review paper, the principle for the detection of various microorganisms (bacteria, directly detected or detected through the emitted toxins or through their DNA, and viruses) and of antibacterial and antiviral peptides based on these responsive PDA vesicles are detailed. The analytical performances obtained, when vesicles are in suspension or immobilized, are given and compared to those of the responsive vesicles mainly based on the vesicle encapsulation method. Many future challenges are then discussed. PMID- 29462871 TI - Taming the Notch Transcriptional Regulator for Cancer Therapy. AB - Abstract Notch signaling is a highly conserved pathway in all metazoans, which is deeply involved in the regulation of cell fate and differentiation, proliferation and migration during development. Research in the last decades has shown that the various components of the Notch signaling cascade are either upregulated or activated in human cancers. Therefore, its downregulation stands as a promising and powerful strategy for cancer therapy. Here, we discuss the recent advances in the development of small molecule inhibitors, blocking antibodies and oligonucleotides that hinder Notch activity, and their outcome in clinical trials. Although Notch was initially identified as an oncogene, later studies showed that it can also act as a tumor suppressor in certain contexts. Further complexity is added by the existence of numerous Notch family members, which exert different activities and can be differentially targeted by inhibitors, potentially accounting for contradictory data on their therapeutic efficacy. Notably, recent evidence supports the rationale for combinatorial treatments including Notch inhibitors, which appear to be more effective than single agents in fighting cancer. PMID- 29462873 TI - The Lewis Pair Polymerization of Lactones Using Metal Halides and N-Heterocyclic Olefins: Theoretical Insights. AB - Lewis pair polymerization employing N-Heterocyclic olefins (NHOs) and simple metal halides as co-catalysts has emerged as a useful tool to polymerize diverse lactones. To elucidate some of the mechanistic aspects that remain unclear to date and to better understand the impact of the metal species, computational methods have been applied. Several key aspects have been considered: (1) the formation of NHO-metal halide adducts has been evaluated for eight different NHOs and three different Lewis acids, (2) the coordination of four lactones to MgCl2 was studied and (3) the deprotonation of an initiator (butanol) was investigated in the presence and absence of metal halide for one specific Lewis pair. It was found that the propensity for adduct formation can be influenced, perhaps even designed, by varying both organic and metallic components. Apart from the NHO backbone, the substituents on the exocyclic, olefinic carbon have emerged as interesting tuning site. The tendency to form adducts is ZnCl2 > MgCl2 > LiCl. If lactones coordinate to MgCl2, the most likely binding mode is via the carbonyl oxygen. A chelating coordination cannot be ruled out and seems to gain importance upon increasing ring-size of the lactone. For a representative NHO, it is demonstrated that in a metal-free setting an initiating alcohol cannot be deprotonated, while in the presence of MgCl2 the same process is exothermic with a low barrier. PMID- 29462872 TI - Ten Years of Experience in Contraception Options for Teenagers in a Family Planning Center in Thrace and Review of the Literature. AB - Abstract: Introduction: The goal of our study was to investigate and evaluate the contraceptive behavior in teenagers from our family planning centre that services two different religious and socioeconomic populations living in the Thrace area. Methods: During the last 10 years 115 Christian Orthodox (group A) and 53 Muslim teenagers (group B) were enrolled in our retrospective study. Contraceptive practice attitudes were assessed by a questionnaire. Religion, demographics, socio-economic characteristics were key factors used to discuss contraception and avoid unplanned pregnancy in each group and to compare with the contraceptive method used. Results: The most used contraceptive method-about two times more frequently-among Christian Orthodox participants was the oral contraceptive pill (p = 0.015; OR = 1.81, 95% CI = 1.13-2.90), while in the other group the use of condoms and IUDs was seven and three times more frequent, respectively. Our family planning centre was the main source of information for contraception. Conclusions: During adolescence, the existence of a family planning centre and participation in family planning programs plays a crucial role to help the teenagers to improve their knowledge and choose an effective contraception method. PMID- 29462874 TI - Pd-Catalyzed, Highly Selective C(sp2)-Br Bond Coupling Reactions of o-(or m-, or p-) Chloromethyl Bromobenzene with Arylboronic Acids. AB - Highly selective C(sp2)-C(sp2) cross-coupling of dihalogenated hydrocarbons comprising C(sp2)-Br and C(sp3)-Cl bonds with arylboronic acids is reported. This highly selective coupling reaction of the C(sp2)-Br bond is successfully achieved using Pd(OAc)2 and PCy3.HBF4 as the palladium source and ligand, respectively. A series of chloromethyl-1,1'-biphenyl compounds are obtained in moderate-to excellent yields. Moreover, this protocol can be extended to the one-pot dual arylation of 1-bromo-4-(chloromethyl)benzene with two arylboronic acids, leading to diverse unsymmetrical 4-benzyl-1,1'-biphenyl derivatives.

AB - The current study seeks to resolve the discrepancy in the literature regarding the cross-kingdom transfer of plant microRNAs (miRNAs) into mammals using an improved miRNA processing and detection method. Two studies utilizing C57BL/6 mice were performed. In the first study, mice were fed an AIN-93M diet and gavaged with water, random deoxynucleotide triphosphates (dNTP) or isolated corn miRNAs for two weeks (n = 10 per group). In the second study, mice were fed an AIN-93M diet, or the diet supplemented with 3% fresh or autoclaved corn powder for two weeks (n = 10 per group). Corn miRNA levels were analyzed in blood and tissue samples by real-time PCR (RT-PCR) following periodate oxidation and beta elimination treatments to eliminate artifacts. After removing false positive detections, there were no differences in corn miRNA levels between control and treated groups in cecal, fecal, liver and blood samples. Using an in vitro digestion system, corn miRNAs in AIN-93M diet or in the extracts were found to be extensively degraded. Less than 1% was recovered in the gastrointestinal tract after oral and gastric phases. In conclusion, no evidence of increased levels of corn miRNAs in whole blood or tissues after supplementation of corn miRNAs in the diet was observed in a mouse model. PMID- 29462876 TI - Narcolepsy and Psychiatric Disorders: Comorbidities or Shared Pathophysiology? AB - Narcolepsy and psychiatric disorders have a significant but unrecognized relationship, which is an area of evolving interest, but unfortunately, the association is poorly understood. It is not uncommon for the two to occur co morbidly. However, narcolepsy is frequently misdiagnosed initially as a psychiatric condition, contributing to the protracted time to accurate diagnosis and treatment. Narcolepsy is a disabling neurodegenerative condition that carries a high risk for development of social and occupational dysfunction. Deterioration in function may lead to the secondary development of psychiatric symptoms. Inversely, the development of psychiatric symptoms can lead to the deterioration in function and quality of life. The overlap in pharmaceutical intervention may further enhance the difficulty to distinguish between diagnoses. Comprehensive care for patients with narcolepsy should include surveillance for psychiatric illness and appropriate treatment when necessary. Further research is necessary to better understand the underlying pathophysiology between psychiatric disease and narcolepsy. PMID- 29462877 TI - Characterization of the Symbiotic Nitrogen-Fixing Common Bean Low Phytic Acid (lpa1) Mutant Response to Water Stress. AB - The common bean (Phaseolus vulgaris L.) low phytic acid (lpa1) biofortified genotype produces seeds with improved nutritional characteristics and does not display negative pleiotropic effects. Here we demonstrated that lpa1 plants establish an efficient nitrogen-fixing symbiosis with Rhizobium etli CE3. The lpa1 nodules showed a higher expression of nodule-function related genes than the nodules of the parental wild type genotype (BAT 93). We analyzed the response to water stress of lpa1 vs. BAT 93 plants grown under fertilized or under symbiotic N2-fixation conditions. Water stress was induced by water withholding (up to 14% soil moisture) to fertilized or R. etli nodulated plants previously grown with normal irrigation. The fertilized lpa1 plants showed milder water stress symptoms during the water deployment period and after the rehydration recovery period when lpa1 plants showed less biomass reduction. The symbiotic water-stressed lpa1 plants showed decreased nitrogenase activity that coincides with decreased sucrose synthase gene expression in nodules; lower turgor weight to dry weight (DW) ratio, which has been associated with higher drought resistance index; downregulation of carbon/nitrogen (C/N)-related and upregulation of stress related genes. Higher expression of stress-related genes was also observed in bacteroids of stressed lpa1 plants that also displayed very high expression of the symbiotic cbb3 oxidase (fixNd). PMID- 29462878 TI - Diagnostic Utility of High Sensitivity Troponins for Echocardiographic Markers of Structural Heart Disease. AB - The conventional use of high-sensitivity troponins (hs-troponins) is for diagnosing myocardial infarction however they also have a role in chronic disease management. This pilot study assessed the relationship of hs-troponins with echocardiographic markers of left ventricular hypertrophy (LVH) and structural heart disease (SHD). Patients undergoing computer gomography (CT) coronary angiogram for low-intermediate risk chest pain and healthy volunteers were recruited. Hs-troponins Singulex I, Abbott I and Roche T and N-terminal pro-brain natriuretic peptide (NT-proBNP) were evaluated in relation to SHD parameters including left ventricular hypertrophy (LVHEcho) and left atrial enlargement (LAEEcho) on echocardiography. 78 subjects who underwent echocardiography were included in this study. C-statistics (95% confidence interval) of the four biomarkers for predicting LVHEcho were 0.84 (0.72-0.92), 0.84 (0.73-0.92), 0.75 (0.63-0.85) and 0.62 (0.49-0.74); for LAEEcho 0.74 (0.6-0.85), 0.78 (0.66-0.88), 0.55 (0.42-0.67) and 0.68 (0.62-0.85); and composite SHD 0.79 (0.66-0.88), 0.87 (0.75-0.94), 0.62 (0.49-0.73) and 0.74 (0.62-0.84) respectively. Optimal cut points for SHD were >1.2 ng/L, >1.6 ng/L, >8 ng/L and >18 pmol/L respectively. These results advocate the potential role of hs-troponins as screening tools for structural heart disease with theranostic implications. PMID- 29462879 TI - Chondrocytes Contribute to Alphaviral Disease Pathogenesis as a Source of Virus Replication and Soluble Factor Production. AB - Arthritogenic alphavirus infections often result in debilitating musculoskeletal disorders that affect the joints, muscle, and bone. In order to evaluate the infection profile of primary human skeletal muscle and chondrocyte cells to Ross River virus (RRV) in vitro, cells were infected at a multiplicity of infection (MOI) of 1 over a period of two days. Viral titers were determined by plaque assay and cytokine expression by Bio-Plex(r) assays using the supernatants harvested. Gene expression studies were conducted using total RNA isolated from cells. Firstly, we show that RRV RNA is detected in chondrocytes from infected mice in vivo. Both human primary skeletal muscle and chondrocyte cells are able to support productive RRV infection in vitro. We also report the production of soluble host factors including the upregulation of heparanase (HPSE) and inflammatory host factors such as interleukin-6 (IL-6), monocyte chemoattractant protein 1 (MCP-1), RANTES (regulated on activation, normal T cell expressed and secreted), interferon gamma (IFN-gamma), and tumor necrosis factor alpha (TNF alpha), which are also present during clinical disease in humans. Our study is the first to demonstrate that human chondrocyte cells are permissive to RRV infection, support the production of infectious virus, and produce soluble factors including HPSE, which may contribute to joint degradation and the pathogenesis of disease. PMID- 29462880 TI - Benzothiophenone Derivatives Targeting Mutant Forms of Estrogen Receptor-alpha in Hormone-Resistant Breast Cancers. AB - Estrogen receptor-alpha positive (ERalpha+) breast cancers represent 75% of all invasive breast cancer cases, while de novo or acquired resistance to ER-directed therapy is also on the rise. Numerous factors contribute to this phenomenon including the recently-reported ESR1 gene mutations such as Y537S, which amplifies co-activator interactions with ERalpha and promotes constitutive activation of ERalpha function. Herein, we propose that direct targeting of the activation function-2 (AF2) site on ERalpha represents a promising alternative therapeutic strategy to overcome mutation-driven resistance in breast cancer. A systematic computer-guided drug discovery approach was employed to develop a potent ERalpha inhibitor that was extensively evaluated by a series of experiments to confirm its AF2-specific activity. We demonstrate that the developed small-molecule inhibitor effectively prevents ERalpha-coactivator interactions and exhibits a strong anti-proliferative effect against tamoxifen resistant cells, as well as downregulates ERalpha-dependent genes and effectively diminishes the receptor binding to chromatin. Notably, the identified lead compound successfully inhibits known constitutively-active, resistance-associated mutant forms of ERalpha observed in clinical settings. Overall, this study reports the development of a novel class of ERalpha AF2 inhibitors, which have the potential to effectively inhibit ERalpha activity by a unique mechanism and to circumvent the issue of mutation-driven resistance in breast cancer. PMID- 29462881 TI - Healthiness of Food and Beverages for Sale at Two Public Hospitals in New South Wales, Australia. AB - (1) Background: Our aim was to conduct objective, baseline food environment audits of two major western Sydney public hospitals and compare them to recently revised state nutritional guidelines. (2) Methods: A cross-sectional assessment was conducted (June-July2017) across 14 fixed food outlets and 70 vending machines in two hospitals using an audit tool designed to assess the guideline's key food environment parameters of availability, placement, and promotion of 'Everyday' (healthy) and 'Occasional' (less healthy) products. (3) Results: Availability: Overall, Everyday products made up 51% and 44% of all products available at the two hospitals. Only 1/14(7%) fixed outlets and 16/70(23%) vending machines met the guideline's availability benchmarks of >=75% Everyday food and beverages. Proportion of Everyday products differed among different types of food outlets (cafe, cafeteria, convenience stores). Placement: On average, food outlets did not meet recommendations of limiting Occasional products in prominent positions, with checkout areas and countertops displaying over 60% Occasional items. Promotion: Over two-thirds of meal deals at both hospitals included Occasional products. (4) Conclusion: Baseline audit results show that substantial improvements in availability, placement, and promotion can be made at these public hospitals to meet the nutrition guidelines. Audits of other NSW hospitals using the developed tool are needed to investigate similarities and differences in food environment between sites. These findings highlight the need for ongoing tracking to inform whether the revised guidelines are leading to improved food environments in health facilities. PMID- 29462884 TI - An Efficient Framework Model for Optimizing Routing Performance in VANETs. AB - Routing in Vehicular Ad hoc Networks (VANET) is a bit complicated because of the nature of the high dynamic mobility. The efficiency of routing protocol is influenced by a number of factors such as network density, bandwidth constraints, traffic load, and mobility patterns resulting in frequency changes in network topology. Therefore, Quality of Service (QoS) is strongly needed to enhance the capability of the routing protocol and improve the overall network performance. In this paper, we introduce a statistical framework model to address the problem of optimizing routing configuration parameters in Vehicle-to-Vehicle (V2V) communication. Our framework solution is based on the utilization of the network resources to further reflect the current state of the network and to balance the trade-off between frequent changes in network topology and the QoS requirements. It consists of three stages: simulation network stage used to execute different urban scenarios, the function stage used as a competitive approach to aggregate the weighted cost of the factors in a single value, and optimization stage used to evaluate the communication cost and to obtain the optimal configuration based on the competitive cost. The simulation results show significant performance improvement in terms of the Packet Delivery Ratio (PDR), Normalized Routing Load (NRL), Packet loss (PL), and End-to-End Delay (E2ED). PMID- 29462882 TI - Glycosylation as a Main Regulator of Growth and Death Factor Receptors Signaling. AB - Glycosylation is a very frequent and functionally important post-translational protein modification that undergoes profound changes in cancer. Growth and death factor receptors and plasma membrane glycoproteins, which upon activation by extracellular ligands trigger a signal transduction cascade, are targets of several molecular anti-cancer drugs. In this review, we provide a thorough picture of the mechanisms bywhich glycosylation affects the activity of growth and death factor receptors in normal and pathological conditions. Glycosylation affects receptor activity through three non-mutually exclusive basic mechanisms: (1) by directly regulating intracellular transport, ligand binding, oligomerization and signaling of receptors; (2) through the binding of receptor carbohydrate structures to galectins, forming a lattice thatregulates receptor turnover on the plasma membrane; and (3) by receptor interaction with gangliosides inside membrane microdomains. Some carbohydrate chains, for example core fucose and beta1,6-branching, exert a stimulatory effect on all receptors, while other structures exert opposite effects on different receptors or in different cellular contexts. In light of the crucial role played by glycosylation in the regulation of receptor activity, the development of next-generation drugs targeting glyco-epitopes of growth factor receptors should be considered a therapeutically interesting goal. PMID- 29462883 TI - Using Polarized Spectroscopy to Investigate Order in Thin-Films of Ionic Self Assembled Materials Based on Azo-Dyes. AB - Three series of ionic self-assembled materials based on anionic azo-dyes and cationic benzalkonium surfactants were synthesized and thin films were prepared by spin-casting. These thin films appear isotropic when investigated with polarized optical microscopy, although they are highly anisotropic. Here, three series of homologous materials were studied to rationalize this observation. Investigating thin films of ordered molecular materials relies to a large extent on advanced experimental methods and large research infrastructure. A statement that in particular is true for thin films with nanoscopic order, where X-ray reflectometry, X-ray and neutron scattering, electron microscopy and atom force microscopy (AFM) has to be used to elucidate film morphology and the underlying molecular structure. Here, the thin films were investigated using AFM, optical microscopy and polarized absorption spectroscopy. It was shown that by using numerical method for treating the polarized absorption spectroscopy data, the molecular structure can be elucidated. Further, it was shown that polarized optical spectroscopy is a general tool that allows determination of the molecular order in thin films. Finally, it was found that full control of thermal history and rigorous control of the ionic self-assembly conditions are required to reproducibly make these materials of high nanoscopic order. Similarly, the conditions for spin-casting are shown to be determining for the overall thin film morphology, while molecular order is maintained. PMID- 29462885 TI - Hypoxia Activates Src and Promotes Endocytosis Which Decreases MMP-2 Activity and Aggravates Renal Interstitial Fibrosis. AB - The aggravation of renal interstitial fibrosis in the advanced-stage of chronic kidney disease is related to decreased matrix metalloproteinase-2 (MMP-2) activity, which is induced by hypoxia in the kidney; however, the specific mechanism remains unclear. We previously demonstrated that inhibition of Caveolin 1, a key gene involved in endocytosis, increased MMP-2 activity in hypoxic HK-2 cells. It has been reported that activated Src (phospho-Src Tyr416) is a key molecule in multiple fibrotic pathways. However, whether Src functions on the regulation of Caveolin-1 and MMP-2 activity in hypoxic HK-2 cells remains poorly understood. To explore the underlying mechanism, a rat model of renal interstitial fibrosis was established, then we observed obvious hypoxia in fibrotic kidney tissue and the protein levels of phospho-Src and Caveolin-1 increased, while MMP-2 activity decreased. Next, we treated HK-2 cells with the phospho-Src inhibitor PP1. Compared with normal cells grown in hypoxia, in cells treated with PP1, the protein levels of phospho-Src and Caveolin-1 decreased, as did the protein levels of the MMP-2-activity-regulated molecules RECK (reversion inducing-cysteine-rich protein with kazal motifs) and TIMP-2 (tissue inhibitor of metalloproteinase-2), while the protein level of MT1-MMP (membrane type 1-matrix metalloproteinase) increased and MMP-2 activity was enhanced. Therefore, hypoxia promotes the phosphorylation of Src and phospho-Src can enhance the endocytosis of HK-2 cells, which leads to decreased MMP-2 activity and aggravates renal interstitial fibrosis. PMID- 29462886 TI - Lung Macrophage Phenotypes and Functional Responses: Role in the Pathogenesis of COPD. AB - Lung macrophages (LMs) are essential immune effector cells that are pivotal in both innate and adaptive immune responses to inhaled foreign matter. They either reside within the airways and lung tissues (from early life) or are derived from blood monocytes. Similar to macrophages in other organs and tissues, LMs have natural plasticity and can change phenotype and function depending largely on the microenvironment they reside in. Phenotype changes in lung tissue macrophages have been implicated in chronic inflammatory responses and disease progression of various chronic lung diseases, including Chronic Obstructive Pulmonary Disease (COPD). LMs have a wide variety of functional properties that include phagocytosis (inorganic particulate matter and organic particles, such as viruses/bacteria/fungi), the processing of phagocytosed material, and the production of signaling mediators. Functioning as janitors of the airways, they also play a key role in removing dead and dying cells, as well as cell debris (efferocytic functions). We herein review changes in LM phenotypes during chronic lung disease, focusing on COPD, as well as changes in their functional properties as a result of such shifts. Targeting molecular pathways involved in LM phenotypic shifts could potentially allow for future targeted therapeutic interventions in several diseases, such as COPD.

AB - This study focuses on understanding factors that influence food agency in the Spanish population, specifically with regard to cooking habits, knowledge, and determinants and their possible relationship with body weight. A cross-sectional telephone survey was conducted. Individuals were asked about their cooking responsibilities, how they learned to cook, factors that affect their food choices, and their preferred cooking techniques. Anthropometric data were also recorded. Participants were randomly selected, and we finally had 2026 respondents aged >=18 years (60% women, 40% men). A total of 90.5% of participants stated that they had cooking skills. Women were mainly responsible for cooking tasks (p < 0.05) at all ages. A significantly higher proportion of people under 50 years self-reported that they were "able to cook" in comparison with groups over 50 years. Regardless of age, most participants learned to cook either by practice (43.3%) or from a family member (42.2%). Men tended to be more autodidactic, whereas women reported learning from family. No relation was found between weight status and the evaluated factors investigated. In conclusion, women bear the responsibility for the entire cooking process in families, indicating a gender gap in the involvement of men in cooking responsibilities and competence. More research is needed to assess the influence of cooking knowledge on obesity prevention. PMID- 29462888 TI - Microwave-Assisted Extraction for Microalgae: From Biofuels to Biorefinery. AB - The commercial reality of bioactive compounds and oil production from microalgal species is constrained by the high cost of production. Downstream processing, which includes harvesting and extraction, can account for 70-80% of the total cost of production. Consequently, from an economic perspective extraction technologies need to be improved. Microalgal cells are difficult to disrupt due to polymers within their cell wall such as algaenan and sporopollenin. Consequently, solvents and disruption devices are required to obtain products of interest from within the cells. Conventional techniques used for cell disruption and extraction are expensive and are often hindered by low efficiencies. Microwave-assisted extraction offers a possibility for extraction of biochemical components including lipids, pigments, carbohydrates, vitamins and proteins, individually and as part of a biorefinery. Microwave technology has advanced since its use in the 1970s. It can cut down working times and result in higher yields and purity of products. In this review, the ability and challenges in using microwave technology are discussed for the extraction of bioactive products individually and as part of a biorefinery approach.

AB - The standard of treatment for botulism, equine antitoxin, is a foreign protein with associated safety issues and a short serum half-life which excludes its use as a prophylactic antitoxin and makes it a less-than-optimal therapeutic. Due to these limitations, a recombinant monoclonal antibody (mAb) product is preferable. It has been shown that combining three mAbs that bind non-overlapping epitopes leads to highly potent botulinum neurotoxin (BoNT) neutralization. Recently, a triple human antibody combination for BoNT/A has demonstrated potent toxin neutralization in mouse models with no serious adverse events when tested in a Phase I clinical trial. However, a triple antibody therapeutic poses unique development and manufacturing challenges. Thus, potentially to streamline development of BoNT antitoxins, we sought to achieve the potency of multiple mAb combinations in a single IgG-based molecule that has a long serum half-life. The design, production, and testing of a single tri-epitopic IgG1-based mAb (TeAb) containing the binding sites of each of the three parental BoNT/A mAbs yielded an antibody of nearly equal potency to the combination. The approach taken here could be applied to the design and creation of other multivalent antibodies that could be used for a variety of applications, including toxin elimination. PMID- 29462890 TI - Antiproliferative Activity of Glycosaminoglycan-Like Polysaccharides Derived from Marine Molluscs. AB - Despite the increasing availability of new classes of cancer treatment, such as immune- and targeted therapies, there remains a need for the development of new antiproliferative/cytotoxic drugs with improved pharmacological profiles that can also overcome drug resistant forms of cancer. In this study, we have identified, and characterised, a novel marine polysaccharide with the potential to be developed as an anticancer agent. Sulphated polysaccharides isolated from the common cockle (Cerastoderma edule) were shown to have antiproliferative activity on chronic myelogenous leukaemia and relapsed acute lymphoblastic leukaemia cell lines. Disaccharide and monosaccharide analysis of these marine polysaccharides confirmed the presence of glycosaminoglycan-like structures that were enriched in ion-exchange purified fractions containing antiproliferative activity. The antiproliferative activity of these glycosaminoglycan-like marine polysaccharides was shown to be susceptible to heparinase but not chondrotinase ABC digestion. This pattern of enzymatic and antiproliferative activity has not previously been seen, with either marine or mammalian glycosaminoglycans. As such, our findings suggest we have identified a new type of marine derived heparan sulphate/heparin like polysaccharide with potent anticancer properties. PMID- 29462891 TI - Hyperpolarized Amino Acid Derivatives as Multivalent Magnetic Resonance pH Sensor Molecules. AB - pH is a tightly regulated physiological parameter that is often altered in diseased states like cancer. The development of biosensors that can be used to non-invasively image pH with hyperpolarized (HP) magnetic resonance spectroscopic imaging has therefore recently gained tremendous interest. However, most of the known HP-sensors have only individually and not comprehensively been analyzed for their biocompatibility, their pH sensitivity under physiological conditions, and the effects of chemical derivatization on their logarithmic acid dissociation constant (pKa). Proteinogenic amino acids are biocompatible, can be hyperpolarized and have at least two pH sensitive moieties. However, they do not exhibit a pH sensitivity in the physiologically relevant pH range. Here, we developed a systematic approach to tailor the pKa of molecules using modifications of carbon chain length and derivatization rendering these molecules interesting for pH biosensing. Notably, we identified several derivatives such as [1-13C]serine amide and [1-13C]-2,3-diaminopropionic acid as novel pH sensors. They bear several spin-1/2 nuclei (13C, 15N, 31P) with high sensitivity up to 4.8 ppm/pH and we show that 13C spins can be hyperpolarized with dissolution dynamic polarization (DNP). Our findings elucidate the molecular mechanisms of chemical shift pH sensors that might help to design tailored probes for specific pH in vivo imaging applications. PMID- 29462892 TI - High Prevalence of Quorum-Sensing and Quorum-Quenching Activity among Cultivable Bacteria and Metagenomic Sequences in the Mediterranean Sea. AB - There is increasing evidence being accumulated regarding the importance of N-acyl homoserine lactones (AHL)-mediated quorum-sensing (QS) and quorum-quenching (QQ) processes in the marine environment, but in most cases, data has been obtained from specific microhabitats, and subsequently little is known regarding these activities in free-living marine bacteria. The QS and QQ activities among 605 bacterial isolates obtained at 90 and 2000 m depths in the Mediterranean Sea were analyzed. Additionally, putative QS and QQ sequences were searched in metagenomic data obtained at different depths (15-2000 m) at the same sampling site. The number of AHL producers was higher in the 90 m sample (37.66%) than in the 2000 m sample (4.01%). However, the presence of QQ enzymatic activity was 1.63-fold higher in the 2000 m sample. The analysis of putative QQ enzymes in the metagenomes supports the relevance of QQ processes in the deepest samples, found in cultivable bacteria. Despite the unavoidable biases in the cultivation methods and biosensor assays and the possible promiscuous activity of the QQ enzymes retrieved in the metagenomic analysis, the results indicate that AHL-related QS and QQ processes could be common activity in the marine environment. PMID- 29462893 TI - Social Determinants of Perceived Discrimination among Black Youth: Intersection of Ethnicity and Gender. AB - Most of the existing sociological and epidemiological literature has focused on the protective effects of high socioeconomic status (SES) on population health through reducing exposure to risk factors and increasing human and material resources that can mitigate adversities. Recent studies, however, have documented poor mental health of high SES Blacks, particularly African American males and Caribbean Black females. The literature also shows a link between perceived discrimination and poor mental health. To better understand the extra costs of upward social mobility for minority populations, this study explored ethnic by gender variations in the associations between SES indicators and perceived discrimination in an ethnically diverse national sample of Black youth. This study included 810 African American and 360 Caribbean Black youth who were sampled in the National Survey of American Life-Adolescent supplement (NSAL-A). Three SES indicators (financial hardship, family income, and income to needs ratio) were the independent variables. The dependent variable was perceived (daily) discrimination. Age was the covariate. Ethnicity and gender were the focal moderators. Linear regressions were used for data analysis in the pooled sample and also based on the intersection of ethnicity and gender. Considerable gender by ethnicity variations were found in the patterns of the associations between SES indicators and perceived discrimination. Financial hardship was a risk factor for perceived discrimination in African American males only. High family income and income to needs ratio were associated with high (but not low) perceived discrimination in African American males and Caribbean Black females. SES indicators were not associated with perceived discrimination for African American females or Caribbean Black males. When it comes to Black youth, high SES is not always protective. Whether SES reduces or increases perceived discrimination among Black youth depends on the intersection of ethnicity by gender. Additional research is needed to understand why and how high SES increases exposure and vulnerability to discrimination for some groups of Black youth. PMID- 29462894 TI - Modeling the Role of Wnt Signaling in Human and Drosophila Stem Cells. AB - The discovery of induced pluripotent stem (iPS) cells, barely more than a decade ago, dramatically transformed the study of stem cells and introduced a completely new way to approach many human health concerns. Although advances have pushed the field forward, human application remains some years away, in part due to the need for an in-depth mechanistic understanding. The role of Wnts in stem cells predates the discovery of iPS cells with Wnts established as major pluripotency promoting factors. Most work to date has been done using mouse and tissue culture models and few attempts have been made in other model organisms, but the recent combination of clustered regularly interspaced short palindromic repeats (CRISPR) gene editing with iPS cell technology provides a perfect avenue for exploring iPS cells in model organisms. Drosophila is an ideal organism for such studies, but fly iPS cells have not yet been made. In this opinion article, we draw parallels between Wnt signaling in human and Drosophila stem cell systems, propose ways to obtain Drosophila iPS cells, and suggest ways to exploit the versatility of the Drosophila system for future stem cell studies. PMID- 29462895 TI - Design, Synthesis and DFT/DNP Modeling Study of New 2-Amino-5-arylazothiazole Derivatives as Potential Antibacterial Agents. AB - A new series of 2-amino-5-arylazothiazole derivatives has been designed and synthesized in 61-78% yields and screened as potential antibacterial drug candidates against the Gram negative bacterium Escherichia coli. The geometry of the title compounds were being studied using the Material Studio package and semi core pseudopods calculations (dspp) were performed with the double numerica basis sets plus polarization functional (DNP) to predict the properties of materials using the hybrid FT/B3LYP method. Modeling calculations, especially the (EH-EL) difference and the energetic parameters revealed that some of the title compounds may be promising tools for further research work and the activity is structure dependent. PMID- 29462896 TI - Dietary Fiber Treatment Corrects the Composition of Gut Microbiota, Promotes SCFA Production, and Suppresses Colon Carcinogenesis. AB - Epidemiological studies propose a protective role for dietary fiber in colon cancer (CRC). One possible mechanism of fiber is its fermentation property in the gut and ability to change microbiota composition and function. Here, we investigate the role of a dietary fiber mixture in polyposis and elucidate potential mechanisms using TS4Cre*cAPCl degrees x468 mice. Stool microbiota profiling was performed, while functional prediction was done using PICRUSt. Stool short-chain fatty acid (SCFA) metabolites were measured. Histone acetylation and expression of SCFA butyrate receptor were assessed. We found that SCFA-producing bacteria were lower in the polyposis mice, suggesting a decline in the fermentation product of dietary fibers with polyposis. Next, a high fiber diet was given to polyposis mice, which significantly increased SCFA-producing bacteria as well as SCFA levels. This was associated with an increase in SCFA butyrate receptor and a significant decrease in polyposis. In conclusion, we found polyposis to be associated with dysbiotic microbiota characterized by a decline in SCFA-producing bacteria, which was targetable by high fiber treatment, leading to an increase in SCFA levels and amelioration of polyposis. The prebiotic activity of fiber, promoting beneficial bacteria, could be the key mechanism for the protective effects of fiber on colon carcinogenesis. SCFA promoting fermentable fibers are a promising dietary intervention to prevent CRC. PMID- 29462897 TI - Molecular Cloning and Characterization of a Wild Eggplant Solanum aculeatissimum NBS-LRR Gene, Involved in Plant Resistance to Meloidogyne incognita. AB - Root-knot nematodes, Meloidogyne spp., cause considerable damage in eggplant production. Transferring of resistance genes from wild relatives would be valuable for the continued improvement of eggplant. Solanum aculeatissimum, a wild relative of eggplant possessing resistance to Meloidogyne incognita, is potentially useful for genetically enhancing eggplant. In the present study, we have isolated and characterized a nucleotide-binding site leucine-rich repeat (NBS-LRR) resistance gene, designated as SacMi. The full-length cDNA of the SacMi gene was obtained using the technique of rapid-amplification of cDNA ends (RACE). The open reading frame of the SacMi gene was 4014 bp and encoded a protein of 1338 amino acids. Sequence analysis indicated that SacMi belong to the non- Toll/Interleukin-1 receptor (TIR)-NBS-LRR type disease-resistance genes. Interestingly, quantitative RT-PCR showed that SacMi is expressed at low levels in uninfected roots, but was up-regulated by infection with M. incognita. To investigate the role of SacMi in S. aculeatissimum resistance against M. incognica, the tobacco rattle virus (TRV)-mediated virus-induced gene silencing (VIGS) system was used. Silencing of SacMi enhanced susceptibility of S. aculeatissimum plants to M. incognita, suggesting the possible involvement of SacMi in resistance against M. incognita infection. PMID- 29462898 TI - Do Nonalcoholic Fatty Liver Disease and Fetuin-A Play Different Roles in Symptomatic Coronary Artery Disease and Peripheral Arterial Disease? AB - BACKGROUND AND AIMS: Nonalcoholic fatty liver disease (NAFLD) is strongly associated with both atherosclerotic cardiovascular disease (CVD) and Fetuin-A. However, the association of Fetuin-A with atherosclerosis is more controversial. We hypothesized that the pathogenic interplay of NAFLD, Fetuin-A and atherosclerosis varies based on arterial site. Accordingly, we aimed to assess NAFLD prevalence, Fetuin-A values and their relationship with symptomatic atherosclerosis occurring in different localizations: coronary artery disease (CAD) vs. peripheral arterial disease (PAD). METHODS: One hundred and forty-nine consecutive patients with symptomatic atherosclerotic CVD were recruited: 45 with CAD diagnosed by coronary angiography and 104 with PAD detected by doppler ultrasound and/or computed tomography angiography and/or angiography. NAFLD was diagnosed based on both ultrasonography and exclusion of competing etiologies. Serum Fetuin-A was measured with ELISA. RESULTS: NAFLD was detected in 54% of the overall group, with higher rates in PAD (59%) than CAD (42%) patients. Median Fetuin-A values were 256 (111-662) MUg/mL, higher in patients with CAD (378 (124 662) MUg/mL) than those with PAD (236 (111-461) MUg/mL). The main findings were: (1) CAD patients had higher Fetuin-A values and less frequently NAFLD than PAD patients; (2) NAFLD was positively associated with Fetuin-A values; however, this association was limited to CAD patients only; (3) Fetuin-A values were positively associated with both CAD and NAFLD. CONCLUSION: The pathogenic interplay of NAFLD, Fetuin-A and atherosclerosis probably varies according to the arterial site. PMID- 29462899 TI - "I Wouldn't Be Friends with Someone If They Were Liking Too Much Rubbish": A Qualitative Study of Alcohol Brands, Youth Identity and Social Media. AB - The consumption of alcohol by young people remains a major public health concern at both the national and international level. Levels of drinking among 15 yearolds in the United Kingdom (UK) remain significantly higher than the European average. This study explored how alcohol brands are used by young people to develop their desired identities and how these acts of consumption extend to young people's profiles on social media. It also deepens understanding of how alcohol brands are connected to young peoples' concerns about image and peer group dynamics. This involved qualitative focus groups with young people aged 14 17 in Central Scotland. Certain alcohol brands were approved and viewed as socially acceptable by young people, while others were rejected. Children as young as 14 were selecting products to portray a drinking identity that was appropriately aligned to their gender and sexuality. Participants displayed a desire to associate themselves with the mature drinking culture personified by some brands, whilst simultaneously distancing themselves from immature drinking practices associated with others. Publicly associating with alcohol brands on social media carried with it potential risks to peer group acceptance. Understanding how young people perceive alcohol brands, the importance of social media in communicating that identity to their peers and the role that alcohol brands play in adolescent identity formation is an important first step to reforming alcohol marketing regulations. PMID- 29462901 TI - Nanogels for Pharmaceutical and Biomedical Applications and Their Fabrication Using 3D Printing Technologies. AB - Nanogels are hydrogels formed by connecting nanoscopic micelles dispersed in an aqueous medium, which give an opportunity for incorporating hydrophilic payloads to the exterior of the micellar networks and hydrophobic payloads in the core of the micelles. Biomedical and pharmaceutical applications of nanogels have been explored for tissue regeneration, wound healing, surgical device, implantation, and peroral, rectal, vaginal, ocular, and transdermal drug delivery. Although it is still in the early stages of development, due to the increasing demands of precise nanogel production to be utilized for personalized medicine, biomedical applications, and specialized drug delivery, 3D printing has been explored in the past few years and is believed to be one of the most precise, efficient, inexpensive, customizable, and convenient manufacturing techniques for nanogel production. PMID- 29462902 TI - Ring Laser Gyro G-Sensitive Misalignment Calibration in Linear Vibration Environments. AB - The ring laser gyro (RLG) dither axis will bend and exhibit errors due to the specific forces acting on the instrument, which are known as g-sensitive misalignments of the gyros. The g-sensitive misalignments of the RLG triad will cause severe attitude error in vibration or maneuver environments where large amplitude specific forces and angular rates coexist. However, g-sensitive misalignments are usually ignored when calibrating the strapdown inertial navigation system (SINS). This paper proposes a novel method to calibrate the g sensitive misalignments of an RLG triad in linear vibration environments. With the SINS is attached to a linear vibration bench through outer rubber dampers, rocking of the SINS can occur when the linear vibration is performed on the SINS. Therefore, linear vibration environments can be created to simulate the harsh environment during aircraft flight. By analyzing the mathematical model of g sensitive misalignments, the relationship between attitude errors and specific forces as well as angular rates is established, whereby a calibration scheme with approximately optimal observations is designed. Vibration experiments are conducted to calibrate g-sensitive misalignments of the RLG triad. Vibration tests also show that SINS velocity error decreases significantly after g sensitive misalignments compensation. PMID- 29462900 TI - Next Generation Immunotherapy for Pancreatic Cancer: DNA Vaccination is Seeking New Combo Partners. AB - Pancreatic Ductal Adenocarcinoma (PDA) is an almost incurable radio- and chemo resistant tumor, and its microenvironment is characterized by a strong desmoplastic reaction associated with a significant infiltration of T regulatory lymphocytes and myeloid-derived suppressor cells (Tregs, MDSC). Investigating immunological targets has identified a number of metabolic and cytoskeletal related molecules, which are typically recognized by circulating antibodies. Among these molecules we have investigated alpha-enolase (ENO1), a glycolytic enzyme that also acts a plasminogen receptor. ENO1 is also recognized by T cells in PDA patients, so we developed a DNA vaccine that targets ENO1. This efficiently induces many immunological processes (antibody formation and complement-dependent cytotoxicity (CDC)-mediated tumor killing, infiltration of effector T cells, reduction of infiltration of myeloid and Treg suppressor cells), which significantly increase the survival of genetically engineered mice that spontaneously develop pancreatic cancer. Although promising, the ENO1 DNA vaccine does not completely eradicate the tumor, which, after an initial growth inhibition, returns to proliferate again, especially when Tregs and MDSC ensue in the tumor mass. This led us to develop possible strategies for combinatorial treatments aimed to broaden and sustain the antitumor immune response elicited by DNA vaccination. Based on the data we have obtained in recent years, this review will discuss the biological bases of possible combinatorial treatments (chemotherapy, PI3K inhibitors, tumor-associated macrophages, ENO1 inhibitors) that could be effective in amplifying the response induced by the immune vaccination in PDA. PMID- 29462903 TI - Calcium Imaging of GPCR Activation Using Arrays of Reverse Transfected HEK293 Cells in a Microfluidic System. AB - Reverse-transfected cell arrays in microfluidic systems have great potential to perform large-scale parallel screening of G protein-coupled receptor (GPCR) activation. Here, we report the preparation of a novel platform using reverse transfection of HEK293 cells, imaging by stereo-fluorescence microscopy in a flowcell format, real-time monitoring of cytosolic calcium ion fluctuations using the fluorescent protein Cameleon and analysis of GPCR responses to sequential sample exposures. To determine the relationship between DNA concentration and gene expression, we analyzed cell arrays made with variable concentrations of plasmid DNA encoding fluorescent proteins and the Neurokinin 1 (NK1) receptor. We observed pronounced effects on gene expression of both the specific and total DNA concentration. Reverse transfected spots with NK1 plasmid DNA at 1% of total DNA still resulted in detectable NK1 activation when exposed to its ligand. By varying the GPCR DNA concentration in reverse transfection, the sensitivity and robustness of the receptor response for sequential sample exposures was optimized. An injection series is shown for an array containing the NK1 receptor, bitter receptor TAS2R8 and controls. Both receptors were exposed 14 times to alternating samples of two ligands. Specific responses remained reproducible. This platform introduces new opportunities for high throughput screening of GPCR libraries. PMID- 29462904 TI - Effect of Pyruvate Decarboxylase Knockout on Product Distribution Using Pichia pastoris (Komagataella phaffii) Engineered for Lactic Acid Production. AB - Lactic acid is the monomer unit of the bioplastic poly-lactic acid (PLA). One candidate organism for lactic acid production is Pichia pastoris, a yeast widely used for heterologous protein production. Nevertheless, this yeast has a poor fermentative capability that can be modulated by controlling oxygen levels. In a previous study, lactate dehydrogenase (LDH) activity was introduced into P. pastoris, enabling this yeast to produce lactic acid. The present study aimed to increase the flow of pyruvate towards the production of lactic acid in P. pastoris. To this end, a strain designated GLp was constructed by inserting the bovine lactic acid dehydrogenase gene (LDHb) concomitantly with the interruption of the gene encoding pyruvate decarboxylase (PDC). Aerobic fermentation, followed by micro-aerophilic culture two-phase fermentations, showed that the GLp strain achieved a lactic acid yield of 0.65 g/g. The distribution of fermentation products demonstrated that the acetate titer was reduced by 20% in the GLp strain with a concomitant increase in arabitol production: arabitol increased from 0.025 g/g to 0.174 g/g when compared to the GS115 strain. Taken together, the results show a significant potential for P. pastoris in producing lactic acid. Moreover, for the first time, physiological data regarding co-product formation have indicated the redox balance limitations of this yeast. PMID- 29462905 TI - Diversity of Concerns in Recovery after a Nuclear Accident: A Perspective from Fukushima. AB - Since the 2011 Fukushima nuclear accident, tremendous resources have been devoted to recovery, and the Japanese Government is gradually lifting evacuation orders. However, public concerns remain prevalent, affecting some people's return to a normal life and threatening their well-being. This study reviews government reports, academic papers, newspaper articles and conference presentations with the aim of obtaining a better understanding of issues which relate to radiation concerns in the recovery process in the aftermath of the accident. It looks extensively at: (1) the current status of the post-accident operations and existing radiation issues in Fukushima, and (2) approaches taken to engage the public during recovery from five previous comparable nuclear and radiological events: Three Mile Island, Buenos Aires (RA-2 facility), Chernobyl, Goiania and Tokai-mura. The findings indicate that the limitations and emerging challenges of the current recovery operations cause concerns about radiation exposure in various aspects of day-to-day life. Past experiences suggest that long-term management that take a holistic and cohesive approach is critical for restoration of sustainable livelihoods and for social re-integration. Not only actual risks but also public perceptions of risks should be carefully assessed and addressed in the process of environmental remediation.

AB - For answering the growing demand of innovative micro-fluidic devices able to measure the refractive index of samples in extremely low volumes, this paper presents an overview of the performances of a micro-opto-fluidic sensing platform that employs rectangular, miniature hollow glass tubings. The operating principle is described by showing the analytical model of the tubing, obtained as superposition of different optical cavities, and the optical readout method based on spectral reflectivity detection. We have analyzed, in particular, the theoretical and experimental optical features of rectangular tubings with asymmetrical geometry, thus with channel depth larger than the thickness of the glass walls, though all of them in the range of a few tens of micrometers. The origins of the complex line-shape of the spectral response in reflection, due to the different cavities formed by the tubing flat walls and channel, have been investigated using a Fourier transform analysis. The implemented instrumental configuration, based on standard telecom fiberoptic components and a semiconductor broadband optical source emitting in the near infrared wavelength region centered at 1.55 um, has allowed acquisition of reflectivity spectra for experimental verification of the expected theoretical behavior. We have achieved detection of refractive index variations related to the change of concentration of glucose-water solutions flowing through the tubing by monitoring the spectral shift of the optical resonances. PMID- 29462908 TI - Research on the Multiple Factors Influencing Human Identification Based on Pyroelectric Infrared Sensors. AB - Analysis of the multiple factors affecting human identification ability based on pyroelectric infrared technology is a complex problem. First, we examine various sensed pyroelectric waveforms of the human body thermal infrared signal and reveal a mechanism for affecting human identification. Then, we find that the mechanism is decided by the distance, human target, pyroelectric infrared (PIR) sensor, the body type, human moving velocity, signal modulation mask, and Fresnel lens. The mapping relationship between the sensed waveform and multiple influencing factors is established, and a group of mathematical models are deduced which fuse the macro factors and micro factors. Finally, the experimental results show the macro-factors indirectly affect the recognition ability of human based on the pyroelectric technology. At the same time, the correctness and effectiveness of the mathematical models is also verified, which make it easier to obtain more pyroelectric infrared information about the human body for discriminating human targets. PMID- 29462909 TI - Antimicrobial Peptides for Topical Treatment of Osteomyelitis and Implant-Related Infections: Study in the Spongy Bone. AB - We examined the benefits of short linear alpha-helical antimicrobial peptides (AMPs) invented in our laboratory for treating bone infection and preventing microbial biofilm formation on model implants due to causative microorganisms of osteomyelitis. For this purpose, we introduced a model of induced osteomyelitis that utilizes human femur heads obtained from the hospital after their replacement with artificial prostheses. We found that the focus of the infection set up in the spongy part of this bone treated with AMP-loaded calcium phosphate cement was eradicated much more effectively than was the focus treated with antibiotics such as vancomycin or gentamicin loaded into the same cement. This contradicts the minimum inhibitory concentrations (MIC) values of AMPs and antibiotics against some bacterial strains obtained in standard in vitro assays. The formation of microbial biofilm on implants made from poly(methylmethacrylate) based bone cement loaded with AMP was evaluated after the implants' removal from the infected bone sample. AMPs loaded in such model implants prevented microbial adhesion and subsequent formation of bacterial biofilm on their surface. Biofilms did form, on the other hand, on control implants made from the plain cement when these were implanted into the same infected bone sample. These results of the experiments performed in human bone tissue highlight the clinical potential of antimicrobial peptides for use in treating and preventing osteomyelitis caused by resistant pathogens.

AB - Pecan (Carya illinoinensis) kernels have a high phenolics content and a high antioxidant capacity compared to other nuts-traits that have attracted great interest of late. Changes in the total phenolic content (TPC), condensed tannins (CT), total flavonoid content (TFC), five individual phenolics, and antioxidant capacity of five pecan cultivars were investigated during the process of kernel ripening. Ultra-performance liquid chromatography coupled with quadruple time-of flight mass (UPLC-Q/TOF-MS) was also used to analyze the phenolics profiles in mixed pecan kernels. TPC, CT, TFC, individual phenolics, and antioxidant capacity were changed in similar patterns, with values highest at the water or milk stages, lowest at milk or dough stages, and slightly varied at kernel stages. Forty phenolics were tentatively identified in pecan kernels, of which two were first reported in the genus Carya, six were first reported in Carya illinoinensis, and one was first reported in its kernel. The findings on these new phenolic compounds provide proof of the high antioxidant capacity of pecan kernels. PMID- 29462912 TI - UAVs and Machine Learning Revolutionising Invasive Grass and Vegetation Surveys in Remote Arid Lands. AB - The monitoring of invasive grasses and vegetation in remote areas is challenging, costly, and on the ground sometimes dangerous. Satellite and manned aircraft surveys can assist but their use may be limited due to the ground sampling resolution or cloud cover. Straightforward and accurate surveillance methods are needed to quantify rates of grass invasion, offer appropriate vegetation tracking reports, and apply optimal control methods. This paper presents a pipeline process to detect and generate a pixel-wise segmentation of invasive grasses, using buffel grass (Cenchrus ciliaris) and spinifex (Triodia sp.) as examples. The process integrates unmanned aerial vehicles (UAVs) also commonly known as drones, high-resolution red, green, blue colour model (RGB) cameras, and a data processing approach based on machine learning algorithms. The methods are illustrated with data acquired in Cape Range National Park, Western Australia (WA), Australia, orthorectified in Agisoft Photoscan Pro, and processed in Python programming language, scikit-learn, and eXtreme Gradient Boosting (XGBoost) libraries. In total, 342,626 samples were extracted from the obtained data set and labelled into six classes. Segmentation results provided an individual detection rate of 97% for buffel grass and 96% for spinifex, with a global multiclass pixel-wise detection rate of 97%. Obtained results were robust against illumination changes, object rotation, occlusion, background cluttering, and floral density variation. PMID- 29462911 TI - Anti-Inflammatory and Gastroprotective Roles of Rabdosia inflexa through Downregulation of Pro-Inflammatory Cytokines and MAPK/NF-kappaB Signaling Pathways. AB - Globally, gastric ulcer is a vital health hazard for a human. Rabdosia inflexa (RI) has been used in traditional medicine for inflammatory diseases. The present study aimed to investigate the protective effect and related molecular mechanism of RI using lipopolysaccharide (LPS)-induced inflammation in RAW 246.7 cells and HCl/EtOH-induced gastric ulcer in mice. We applied 3-(4,5-dimethyl-thiazol-2-yl) 2,5-diphenyltetrazolium bromide (MTT), nitric oxide (NO), reactive oxygen species (ROS), histopathology, malondialdehyde (MDA), quantitative real-time polymerase chain reaction (qPCR), immunohistochemistry (IHC), and Western blot analyses to evaluate the protective role of RI. Study revealed that RI effectively attenuated LPS-promoted NO and ROS production in RAW 246.7 cells. In addition, RI mitigated gastric oxidative stress by inhibiting lipid peroxidation, elevating NO, and decreasing gastric inflammation. RI significantly halted elevated gene expression of pro-inflammatory cytokines such as tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta), interleukin-6 (IL-6), inducible nitric oxide synthetase (iNOS), and cyclooxygenase-2 (COX-2) in gastric tissue. Likewise, RI markedly attenuated the mitogen-activated protein kinases (MAPKs) phosphorylation, COX-2 expression, phosphorylation and degradation of inhibitor kappa B (IkappaBalpha) and activation of nuclear factor kappa B (NF-kappaB). Thus, experimental findings suggested that the anti-inflammatory and gastroprotective activities of RI might contribute to regulating pro-inflammatory cytokines and MAPK/NF-kappaB signaling pathways.

AB - Disseminating lower-limb injury-prevention exercise programs (LL-IPEPs) with strategies that effectively reach coaches across sporting environments is a way of preventing lower-limb injuries (LLIs) and ensuring safe and sustainable sport participation. The aim of this study was to explore community-Australian Football (community-AF) coaches' perspectives on the strategies they believed would enhance the dissemination and scale-up of LL-IPEPs. Using a qualitative multiple case study design, semi-structured interviews with community-AF coaches in Victoria, Australia, were conducted. Overall, coaches believed a range of strategies were important including: coach education, policy drivers, overcoming potential problem areas, a 'try before you buy approach', presenting empirical evidence and guidelines for injury-prevention exercise programs (IPEPs), forming strategic collaboration and working in partnership, communication and social marketing, public meetings, development of a coach hotline, and targeted multi focused approaches. A shift to a culture whereby evidence-based IPEP practices in community-AF will take time, and persistent commitment by all involved in the sport is important. This will support the creation of strategies that will enhance the dissemination and scale-up of LL-IPEPs across community sport environments. The focus of research needs to continue to identify effective, holistic and multi-level interventions to support coaches in preventing LLIs. This could lead to the determination of successful strategies such as behavioural regulation strategies and emotional coping resources to implement LL-IPEPs into didactic curricula and practice. Producing changes in practice will require attention to which strategies are a priority and the most effective.

AB - Hip fracture commonly results in considerable consequences in terms of disability, mortality, long-term institutional care and cost. Taiwan launched its universal health insurance coverage in 1995, which largely removes financial barriers to health care. This study aims to investigate whether socioeconomic inequality in one-year mortality exists among Taiwanese elderly people. This population-based cohort study included 193,158 elderly patients (>=65 years) admitted for hip fracture between 2000 and 2012. With over a one-year follow-up, 10.52% of the participants died from all causes. The mortality rate was low in the northern part of Taiwan and in urban and high-family-income areas. Multiple Poisson regression models further suggested that the level of >Q1-Q3 and >Q3-Max showed significantly reduced odds ratio of one-year mortality at 0.90 (95% confidence interval (CI), 0.87-0.93) and 0.77 (95% CI, 0.74-0.81), respectively, compared with that of the lowest family income level (i.e., Min.-Q1). Despite a monotonic decline in overall one-year mortality during the study period, socioeconomic inequality in one-year mortality rate remained evident. The annual percentage change in one-year mortality was higher (-2.86) in elderly people from families with high income (>Q3-Max.) than that for elderly patients from family with low income (Min.-Q1, -1.94). Accessibility, rather than affordability, to health care for hip fracture is probably responsible for the observed socioeconomic inequality. PMID- 29462915 TI - Pilocarpine-Induced Status Epilepticus Is Associated with P-Glycoprotein Induction in Cardiomyocytes, Electrocardiographic Changes, and Sudden Death. AB - Sudden unexpected death in epilepsy (SUDEP) is the major cause of death in those patients suffering from refractory epilepsy (RE), with a 24-fold higher risk relative to the normal population. SUDEP risk increases with seizure frequency and/or seizure-duration as in RE and Status Epilepticus (SE). P-glycoprotein (P gp), the product of the multidrug resistant ABCB1-MDR-1 gene, is a detoxifying pump that extrudes drugs out of the cells and can confer pharmacoresistance to the expressing cells. Neurons and cardiomyocytes normally do not express P-gp, however, it is overexpressed in the brain of patients or in experimental models of RE and SE. P-gp was also detected after brain or cardiac hypoxia. We have previously demonstrated that repetitive pentylenetetrazole (PTZ)-induced seizures increase P-gp expression in the brain, which is associated with membrane depolarization in the hippocampus, and in the heart, which is associated with fatal SE. SE can produce hypoxic-ischemic altered cardiac rhythm (HIACR) and severe arrhythmias, and both are related with SUDEP. Here, we investigate whether SE induces the expression of hypoxia-inducible transcription factor (HIF)-1alpha and P-gp in cardiomyocytes, which is associated with altered heart rhythm, and if these changes are related with the spontaneous death rate. SE was induced in Wistar rats once a week for 3 weeks, by lithium-pilocarpine-paradigm. Electrocardiograms, HIF-1alpha, and P-gp expression in cardiomyocytes, were evaluated in basal conditions and 72 h after SE. All spontaneous deaths occurred 48 h after each SE was registered. We observed that repeated SE induced HIF 1alpha and P-gp expression in cardiomyocytes, electrocardiographic (ECG) changes, and a high rate of spontaneous death. Our results suggest that the highly accumulated burden of convulsive stress results in a hypoxic heart insult, where P-gp expression may play a depolarizing role in cardiomyocyte membranes and in the development of the ECG changes, such as QT interval prolongation, that could be related with SUDEP. We postulate that this mechanism could explain, in part, the higher SUDEP risk in patients with RE or SE. PMID- 29462916 TI - Gene Environment Interactions and Predictors of Colorectal Cancer in Family Based, Multi-Ethnic Groups. AB - For the personalization of polygenic/omics-based health care, the purpose of this study was to examine the gene-environment interactions and predictors of colorectal cancer (CRC) by including five key genes in the one-carbon metabolism pathways. In this proof-of-concept study, we included a total of 54 families and 108 participants, 54 CRC cases and 54 matched family friends representing four major racial ethnic groups in southern California (White, Asian, Hispanics, and Black). We used three phases of data analytics, including exploratory, family based analyses adjusting for the dependence within the family for sharing genetic heritage, the ensemble method, and generalized regression models for predictive modeling with a machine learning validation procedure to validate the results for enhanced prediction and reproducibility. The results revealed that despite the family members sharing genetic heritage, the CRC group had greater combined gene polymorphism rates than the family controls (p < 0.05), on MTHFR C677T, MTR A2756G, MTRR A66G, and DHFR 19 bp except MTHFR A1298C. Four racial groups presented different polymorphism rates for four genes (all p < 0.05) except MTHFR A1298C. Following the ensemble method, the most influential factors were identified, and the best predictive models were generated by using the generalized regression models, with Akaike's information criterion and leave-one out cross validation methods. Body mass index (BMI) and gender were consistent predictors of CRC for both models when individual genes versus total polymorphism counts were used, and alcohol use was interactive with BMI status. Body mass index status was also interactive with both gender and MTHFR C677T gene polymorphism, and the exposure to environmental pollutants was an additional predictor. These results point to the important roles of environmental and modifiable factors in relation to gene-environment interactions in the prevention of CRC. PMID- 29462917 TI - Characterization and Determination of Interesterification Markers (Triacylglycerol Regioisomers) in Confectionery Oils by Liquid Chromatography Mass Spectrometry. AB - Interesterification is an industrial transformation process aiming to change the physico-chemical properties of vegetable oils by redistributing fatty acid position within the original constituent of the triglycerides. In the confectionery industry, controlling formation degree of positional isomers is important in order to obtain fats with the desired properties. Silver ion HPLC (High Performance Liquid Chromatography) is the analytical technique usually adopted to separate triglycerides (TAGs) having different unsaturation degrees. However, separation of TAG positional isomers is a challenge when the number of double bonds is the same and the only difference is in their position within the triglyceride molecule. The TAG positional isomers involved in the present work have a structural specificity that require a separation method tailored to the needs of confectionery industry. The aim of this work was to obtain a chromatographic resolution that might allow reliable qualitative and quantitative evaluation of TAG positional isomers within reasonably rapid retention times and robust in respect of repeatability and reproducibility. The resulting analytical procedure was applied both to confectionery raw materials and final products. PMID- 29462918 TI - Out-of-Home Food Consumers in Brazil: What do They Eat? AB - Considering the increased contribution of foods consumed outside home and their potential impact on diet, this study aims to identify eating out patterns and their association with nutritional dietary quality in Brazil. We used the Individual Food Intake Survey 2008-2009, conducted with 34,003 individuals aged 10 and up. We used factor analysis by principal component to identify out-of-home eating patterns and linear regression to explore the association between patterns scores and dietary quality. We identified three food patterns. The "Traditional meal" pattern carried more rice, beans, meat, roots and tubers, pasta, vegetables and eggs. The "typical Brazilian breakfast/tea" pattern carried more fresh bread, margarine, milk, cheese and butter. The "Ultra-processed food" pattern carried more ready-to-eat meals and soft drinks. The "traditional meal" pattern was positively associated with calories from proteins, fiber, iron, potassium and sodium densities, whereas "typical Brazilian breakfast/tea" and "ultra-processed food" patterns were positively associated with energy density, the percentage of calories from lipids or carbohydrates, trans fat and free sugar. Out-of-home eating may have a negative impact on nutritional dietary quality when based on ultra-processed food. However, it is possible to maintain a healthy out-of-home diet with adherence to traditional Brazilian cuisine. PMID- 29462919 TI - Probing the Influence of Linker Length and Flexibility in the Design and Synthesis of New Trehalase Inhibitors. AB - This work aims to synthesize new trehalase inhibitors selective towards the insect trehalase versus the porcine trehalase, in view of their application as potentially non-toxic insecticides and fungicides. The synthesis of a new pseudodisaccharide mimetic 8, by means of a stereoselective alpha-glucosylation of the key pyrrolizidine intermediate 13, was accomplished. The activity of compound 8 as trehalase inhibitor towards C.riparius trehalase was evaluated and the results showed that 8 was active in the MUM range and showed a good selectivity towards the insect trehalase. To reduce the overall number of synthetic steps, simpler and more flexible disaccharide mimetics 9-11 bearing a pyrrolidine nucleus instead of the pyrrolizidine core were synthesized. The biological data showed the key role of the linker chain's length in inducing inhibitory properties, since only compounds 9 (alpha,beta-mixture), bearing a two carbon atom linker chain, maintained activity as trehalase inhibitors. A proper change in the glucosyl donor-protecting groups allowed the stereoselective synthesis of the beta-glucoside 9beta, which was active in the low micromolar range (IC50 = 0.78 MUM) and 12-fold more potent (and more selective) than 9alpha towards the insect trehalase. PMID- 29462920 TI - The Role of the Slc39a Family of Zinc Transporters in Zinc Homeostasis in Skin. AB - The first manifestations that appear under zinc deficiency are skin defects such as dermatitis, alopecia, acne, eczema, dry, and scaling skin. Several genetic disorders including acrodermatitis enteropathica (also known as Danbolt-Closs syndrome) and Brandt's syndrome are highly related to zinc deficiency. However, the zinc-related molecular mechanisms underlying normal skin development and homeostasis, as well as the mechanism by which disturbed zinc homeostasis causes such skin disorders, are unknown. Recent genomic approaches have revealed the physiological importance of zinc transporters in skin formation and clarified their functional impairment in cutaneous pathogenesis. In this review, we provide an overview of the relationships between zinc deficiency and skin disorders, focusing on the roles of zinc transporters in the skin. We also discuss therapeutic outlooks and advantages of controlling zinc levels via zinc transporters to prevent cutaneous disorganization. PMID- 29462921 TI - Complete Chloroplast Genomes of Papaver rhoeas and Papaver orientale: Molecular Structures, Comparative Analysis, and Phylogenetic Analysis. AB - Papaver rhoeas L. and P. orientale L., which belong to the family Papaveraceae, are used as ornamental and medicinal plants. The chloroplast genome has been used for molecular markers, evolutionary biology, and barcoding identification. In this study, the complete chloroplast genome sequences of P. rhoeas and P. orientale are reported. Results show that the complete chloroplast genomes of P. rhoeas and P. orientale have typical quadripartite structures, which are comprised of circular 152,905 and 152,799-bp-long molecules, respectively. A total of 130 genes were identified in each genome, including 85 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. Sequence divergence analysis of four species from Papaveraceae indicated that the most divergent regions are found in the non-coding spacers with minimal differences among three Papaver species. These differences include the ycf1 gene and intergenic regions, such as rpoB trnC, trnD-trnT, petA-psbJ, psbE-petL, and ccsA-ndhD. These regions are hypervariable regions, which can be used as specific DNA barcodes. This finding suggested that the chloroplast genome could be used as a powerful tool to resolve the phylogenetic positions and relationships of Papaveraceae. These results offer valuable information for future research in the identification of Papaver species and will benefit further investigations of these species. PMID- 29462922 TI - Differential Long-Chain Polyunsaturated Fatty Acids Status and Placental Transport in Adolescent Pregnancies. AB - Adolescent pregnancy increases risk of adverse perinatal outcomes. Placental delivery of long-chain polyunsaturated fatty acids (LCPUFA) is essential for fetal growth and development. In this pilot study, we aimed to assess maternal and fetal status of fatty acids (FA) measured at birth and the expression of key genes involved in FA uptake, transport and metabolism in the placenta of fifteen adolescents and fifteen adults. FA were quantified by gas-liquid chromatography. Placental expression of FA transporters was assessed by quantitative real-time polymerase chain reaction (qRT-PCR) and peroxisome proliferator-activated receptor gamma (PPARgamma) was quantified by Western Blot. Adolescents had lower docosahexaenoic acid (DHA, 22:6 n-3) and total n-3 FA levels in maternal erythrocytes and placenta, but these were not different in fetal erythrocytes. Arachidonic acid (AA, 20:4 n-6) concentration was increased in placenta but lower in fetal circulation. Plasma membrane fatty acid binding protein (FABPpm) and fatty acid transport protein (FATP) 4 mRNA expressions were not different, however FATP1, fatty acid translocase (FAT/CD36) and fatty acid binding protein 3 (FABP3) mRNA and PPARgamma protein levels were decreased in placenta of adolescents. Despite significant downregulation of FATP1, CD36 and FABP3, there was only a modest decrease in LCPUFA (10%) and AA (12%) and no difference in DHA content in cord blood, suggesting that FA transfer to the fetus was partially protected by other factors in adolescents from this cohort. PMID- 29462923 TI - The Effect of Whey Protein Supplementation on the Temporal Recovery of Muscle Function Following Resistance Training: A Systematic Review and Meta-Analysis. AB - Whey protein (WP) is a widely consumed nutritional supplement, known to enhance strength and muscle mass during resistance training (RT) regimens. Muscle protein anabolism is acutely elevated following RT, which is further enhanced by WP. As a result, there is reason to suggest that WP supplementation may be an effective nutritional strategy for restoring the acute loss of contractile function that occurs following strenuous RT. This systematic review and meta-analysis provides a synthesis of the literature to date, investigating the effect of WP supplementation on the recovery of contractile function in young, healthy adults. Eight studies, containing 13 randomised control trials (RCTs) were included in this review and meta-analysis, from which individual standardised effect sizes (ESs) were calculated, and a temporal overall ES was determined using a random effects model. Whilst only half of the individual studies reported beneficial effects for WP, the high-quality evidence taken from the 13 RCTs was meta analysed, yielding overall positive small to medium effects for WP from < 24 to 96 h (ES range = 0.4 to 0.7), for the temporal restoration of contractile function compared to the control treatment. Whilst the effects for WP were shown to be consistent over time, these results are limited to 13 RCTs, principally supporting the requirement for further comprehensive research in this area. PMID- 29462925 TI - Insufficient Fruit and Vegetable Intake in a Low- and Middle-Income Setting: A Population-Based Survey in Semi-Urban Tanzania. AB - A daily intake of 5 portions of fruit and vegetables (FV) is recommended for protection against non-communicable diseases (NCDs). Inadequate FV intake is a global problem but resource-poor countries like Tanzania are most deprived and constitute settings where little is known for informing public health interventions. This study aimed to describe the prevalence of inadequate FV intake, frequency of FV intake, portions of FV intake and their associations with socio-demographic/lifestyle factors in South-Eastern Tanzania. Data on FV dietary indicators, socio-demographic factors, smoking, alcohol and healthcare use were collected from 7953 participants (>=15 years) of the population-based MZIMA open community cohort (2012-2013). Multivariable logistic regression was used to examine associations between FV intake outcomes and their socio demographic/lifestyle determinants. Most (82%) of the participants did not meet the recommended daily FV intake While only a fraction consumed fruits daily (15.5%), almost half consumed vegetables daily (44.2%). However, the median (IQR) number of vegetable portions consumed was lower (2(1)/person/day) than that for fruits (2(2)/person/day) People with higher education were more likely to consume fruits daily. Independent correlates of inadequate FV intake included young age, being male, low education, low-income occupations, low alcohol, high tobacco and low healthcare use. Public health interventions should target the socio economically deprived and culturally-rooted preferences while prioritizing promotion of vegetable for most immediate gain in overall FV intake. PMID- 29462924 TI - Achieving Optimal Post-Exercise Muscle Protein Remodeling in Physically Active Adults through Whole Food Consumption. AB - Dietary protein ingestion is critical to maintaining the quality and quantity of skeletal muscle mass throughout adult life. The performance of acute exercise enhances muscle protein remodeling by stimulating protein synthesis rates for several hours after each bout, which can be optimized by consuming protein during the post-exercise recovery period. To date, the majority of the evidence regarding protein intake to optimize post-exercise muscle protein synthesis rates is limited to isolated protein sources. However, it is more common to ingest whole food sources of protein within a normal eating pattern. Emerging evidence demonstrates a promising role for the ingestion of whole foods as an effective nutritional strategy to support muscle protein remodeling and recovery after exercise. This review aims to evaluate the efficacy of the ingestion of nutrient rich and protein-dense whole foods to support post-exercise muscle protein remodeling and recovery with pertinence towards physically active people. PMID- 29462926 TI - Do Current Fortification and Supplementation Programs Assure Adequate Intake of Fat-Soluble Vitamins in Belgian Infants, Toddlers, Pregnant Women, and Lactating Women? AB - Abstracts: Adequate intakes of fat-soluble vitamins are essential to support the growth and development of the foetus, the neonate, and the young child. By means of an online self-administered frequency questionnaire, this study aimed to evaluate the intake of vitamins A, D, E, and K in Belgian infants (n = 455), toddlers (n = 265), pregnant women (n = 161), and lactating women (n = 165). The contribution of foods, fortified foods, and supplements on the total intake was quantified. 5% of toddlers, 16% of pregnant women, and 35% of lactating women had an inadequate vitamin A intake. Conversely, excessive vitamin A intakes were associated with consumption of liver (products). Furthermore, 22% of infants were at risk for inadequate vitamin D intake due to the lack of prophylaxis, while consumption of highly dosed supplements posed a risk for excessive intakes in 6% 26% of infants. Vitamin D intake in pregnant women and lactating women was inadequate (median of 51%, respectively, 60% of the adequate intake). In all groups, the risk for inadequate intake of vitamin E and K was low. Contribution of fortified foods to vitamin A, D, E, and K intake was minor, except in toddlers. National fortification strategies should be investigated as an alternative or additional strategy to prevent vitamin D and A deficiency. There is a need to revise and set uniform supplement recommendations. Finally, non users of vitamin D prophylaxis need to be identified for targeted treatment. PMID- 29462927 TI - Separation Options for Phosphorylated Osteopontin from Transgenic Microalgae Chlamydomonas reinhardtii. AB - Correct folding and post-translational modifications are vital for therapeutic proteins to elicit their biological functions. Osteopontin (OPN), a bone regenerative protein present in a range of mammalian cells, is an acidic phosphoprotein with multiple potential phosphorylation sites. In this study, the ability of unicellular microalgae, Chlamydomonas reinhardtii, to produce phosphorylated recombinant OPN in its chloroplast is investigated. This study further explores the impact of phosphorylation and expression from a "plant-like" algae on separation of OPN. Chromatography resins ceramic hydroxyapatite (CHT) and Gallium-immobilized metal affinity chromatography (Ga-IMAC) were assessed for their binding specificity to phosphoproteins. Non-phosphorylated recombinant OPN expressed in E. coli was used to compare the specificity of interaction of the resins to phosphorylated OPN. We observed that CHT binds OPN by multimodal interactions and was better able to distinguish phosphorylated proteins in the presence of 250 mM NaCl. Ga-IMAC interaction with OPN was not selective to phosphorylation, irrespective of salt, as the resin bound OPN from both algal and bacterial sources. Anion exchange chromatography proved an efficient capture method to partially separate major phosphorylated host cell protein impurities such as Rubisco from OPN. PMID- 29462929 TI - Distributed Water Pollution Source Localization with Mobile UV-Visible Spectrometer Probes in Wireless Sensor Networks. AB - Pollution accidents that occur in surface waters, especially in drinking water source areas, greatly threaten the urban water supply system. During water pollution source localization, there are complicated pollutant spreading conditions and pollutant concentrations vary in a wide range. This paper provides a scalable total solution, investigating a distributed localization method in wireless sensor networks equipped with mobile ultraviolet-visible (UV-visible) spectrometer probes. A wireless sensor network is defined for water quality monitoring, where unmanned surface vehicles and buoys serve as mobile and stationary nodes, respectively. Both types of nodes carry UV-visible spectrometer probes to acquire in-situ multiple water quality parameter measurements, in which a self-adaptive optical path mechanism is designed to flexibly adjust the measurement range. A novel distributed algorithm, called Dual-PSO, is proposed to search for the water pollution source, where one particle swarm optimization (PSO) procedure computes the water quality multi-parameter measurements on each node, utilizing UV-visible absorption spectra, and another one finds the global solution of the pollution source position, regarding mobile nodes as particles. Besides, this algorithm uses entropy to dynamically recognize the most sensitive parameter during searching. Experimental results demonstrate that online multi parameter monitoring of a drinking water source area with a wide dynamic range is achieved by this wireless sensor network and water pollution sources are localized efficiently with low-cost mobile node paths.

AB - New strategies are being investigated to ameliorate the efficacy and reduce the toxicity of the drugs currently used in colorectal cancer (CRC), one of the most common malignancies in the Western world. Data have been accumulated demonstrating that the antineoplastic therapies with either conventional or single-targeted drugs could take advantage from a combined treatment with omega-3 polyunsaturated fatty acids (omega-3 PUFA). These nutrients, shown to be safe at the dosage generally used in human trials, are able to modulate molecules involved in colon cancer cell growth and survival. They have also the potential to act against inflammation, which plays a critical role in CRC development, and to increase the anti-cancer immune response. In the present study, omega-3 PUFA were encapsulated in solid lipid nanoparticles (SLN) having a lipid matrix containing resveratrol esterified to stearic acid. Our aim was to increase the efficiency of the incorporation of these fatty acids into the cells and prevent their peroxidation and degradation. The Resveratrol-based SLN were characterized and investigated for their antioxidant activity. It was observed that the encapsulation of omega-3 PUFA into the SLN enhanced significantly their incorporation in human HT-29 CRC cells in vitro, and their growth inhibitory effects in these cancer cells, mainly by reducing cell proliferation. PMID- 29462930 TI - Flame-Oxidized Stainless-Steel Anode as a Probe in Bioelectrochemical System Based Biosensors to Monitor the Biochemical Oxygen Demand of Wastewater. AB - Biochemical oxygen demand (BOD) is a widely used index of water quality in wastewater treatment; however, conventional measurement methods are time consuming. In this study, we analyzed a novel flame-oxidized stainless steel anode (FO-SSA) for use as the probe of bioelectrochemical system (BES)-based biosensors to monitor the BOD of treated swine wastewater. A thinner biofilm formed on the FO-SSA compared with that on a common carbon-cloth anode (CCA). The FO-SSA was superior to the CCA in terms of rapid sensing; the response time of the FO-SSA to obtain the value of R2 > 0.8 was 1 h, whereas the CCA required 4 h. These results indicate that the FO-SSA offers better performance than traditional CCAs in BES biosensors and can be used to improve biomonitoring of wastewater. PMID- 29462931 TI - Defect-Repairable Latent Feature Extraction of Driving Behavior via a Deep Sparse Autoencoder. AB - Data representing driving behavior, as measured by various sensors installed in a vehicle, are collected as multi-dimensional sensor time-series data. These data often include redundant information, e.g., both the speed of wheels and the engine speed represent the velocity of the vehicle. Redundant information can be expected to complicate the data analysis, e.g., more factors need to be analyzed; even varying the levels of redundancy can influence the results of the analysis. We assume that the measured multi-dimensional sensor time-series data of driving behavior are generated from low-dimensional data shared by the many types of one dimensional data of which multi-dimensional time-series data are composed. Meanwhile, sensor time-series data may be defective because of sensor failure. Therefore, another important function is to reduce the negative effect of defective data when extracting low-dimensional time-series data. This study proposes a defect-repairable feature extraction method based on a deep sparse autoencoder (DSAE) to extract low-dimensional time-series data. In the experiments, we show that DSAE provides high-performance latent feature extraction for driving behavior, even for defective sensor time-series data. In addition, we show that the negative effect of defects on the driving behavior segmentation task could be reduced using the latent features extracted by DSAE. PMID- 29462932 TI - Development and Characterization of Solid Lipid Nanoparticles Loaded with a Highly Active Doxorubicin Derivative. AB - Solid lipid nanoparticles (SLNs) comprise a versatile drug delivery system that has been developed for the treatment of a variety of diseases. The present study will investigate the feasibility of entrapping an active doxorubicin prodrug (a squalenoyl-derivative) in SLNs. The doxorubicin derivative-loaded SLNs are spherically shaped, have a mean diameter of 300-400 nm and show 85% w/w drug entrapment efficiency. The effects on cell growth of loaded SLNs, free doxorubicin and the prodrug have been examined using cytotoxicity and colony forming assays in both human ovarian cancer line A2780 wild-type and doxorubicin resistant cells. Further assessments as to the treatment's ability to induce cell death by apoptosis have been carried out by analyzing annexin-V staining and the activation of caspase-3. The in vitro data demonstrate that the delivery of the squalenoyl-doxorubicin derivative by SLNs increases its cytotoxic activity, as well as its apoptosis effect. This effect was particularly evident in doxorubicin resistant cells. PMID- 29462933 TI - Integrins Were Involved in Soybean Agglutinin Induced Cell Apoptosis in IPEC-J2. AB - Soybean agglutinin (SBA), is a non-fiber carbohydrate related protein and a major anti-nutritional factor. Integrins, transmembrane glycoproteins, are involved in many biological processes. Although recent work suggested that integrins are involved in SBA-induced cell-cycle alterations, no comprehensive study has reported whether integrins are involved in SBA-induced cell apoptosis (SCA) in IPEC-J2. The relationship between SBA and integrins are still unclear. We aimed to elucidate the effects of SBA on IPEC-J2 cell proliferation and cell apoptosis; to study the roles of integrins in IPEC-J2 normal cell apoptosis (NCA) and SCA; and to illustrate the relationship and connection type between SBA and integrins. Thus, IPEC-J2 cells were treated with SBA at the levels of 0, 0.125, 0.25, 0.5, 1.0 or 2.0 mg/mL to determine cell proliferation and cell apoptosis. The cells were divided into control, SBA treated groups, integrin inhibitor groups, and SBA + integrin inhibitor groups to determine the integrin function in SCA. The results showed that SBA significantly (p < 0.05) lowered cell proliferation and induced cell apoptosis in IPEC-J2 (p < 0.05). Inhibition of any integrin type induced the cell apoptosis (p < 0.05) and these integrins were involved in SCA (p < 0.05). Even SBA had no physical connection with integrins, an association was detected between SBA and alpha-actinin-2 ACTN2 (integrin-binding protein). Additionally, SBA reduced the mRNA expression of integrins by down regulating the gene expression level of ACTN2. We concluded an evidence for the anti-nutritional mechanism of SBA by ACTN2 with integrins. Further trials are needed to prove whether ACTN2 is the only protein for connecting SBA with integrin. PMID- 29462934 TI - A Novel Interaction Between the TLR7 and a Colchicine Derivative Revealed Through a Computational and Experimental Study. AB - The Toll-Like Receptor 7 (TLR7) is an endosomal membrane receptor involved in the innate immune system response. Its best-known small molecule activators are imidazoquinoline derivatives such as imiquimod (R-837) and resiquimod (R-848). Recently, an interaction between R-837 and the colchicine binding site of tubulin was reported. To investigate the possibility of an interaction between structural analogues of colchicine and the TLR7, a recent computational model for the dimeric form of the TLR7 receptor was used to determine a possible interaction with a colchicine derivative called CR42-24, active as a tubulin polymerization inhibitor. The estimated values of the binding energy of this molecule with respect to the TLR7 receptor were comparable to the energies of known binders as reported in a previous study. The binding to the TLR7 was further assessed by introducing genetic transformations in the TLR7 gene in cancer cell lines and exposing them to the compound. A negative shift of the IC50 value in terms of cell growth was observed in cell lines carrying the mutated TLR7 gene. The reported study suggests a possible interaction between TLR7 and a colchicine derivative, which can be explored for rational design of new drugs acting on this receptor by using a colchicine scaffold for additional modifications. PMID- 29462935 TI - Asymmetric Synthesis of Spirooxindoles via Nucleophilic Epoxidation Promoted by Bifunctional Organocatalysts. AB - Taking into account the postulated reaction mechanism for the organocatalytic epoxidation of electron-poor olefins developed by our laboratory, we have investigated the key factors able to positively influence the H-bond network installed inside the substrate/catalyst/oxidizing agent. With this aim, we have: (i) tested a few catalysts displaying various effects that noticeably differ in terms of steric hindrance and electron demand; (ii) employed alpha-alkylidene oxindoles decorated with different substituents on the aromatic ring (11a-g), the exocylic double bond (11h-l), and the amide moiety (11m-v). The observed results suggest that the modification of the electron-withdrawing group (EWG) weakly conditions the overall outcomes, and conversely a strong influence is unambiguously ascribable to either the N-protected or N-unprotected lactam framework. Specifically, when the NH free substrates (11m-u) are employed, an inversion of the stereochemical control is observed, while the introduction of a Boc protecting group affords the desired product 12v in excellent enantioselectivity (97:3 er). PMID- 29462937 TI - The Role of Nano-TiO2 Lubricating Fluid on the Hot Rolled Surface and Metallographic Structure of SS41 Steel. AB - In this paper, nano-TiO2lubricating fluid was chosen as an advanced rolling lubricant to investigate its effect on the hot rolled surface and metallographic structure of SS41 steel strips. The tribological performances of nano-TiO2 lubricating fluid were measured by a four-ball tribotester. The hot rolling experiments under different lubrication conditions were carried out by a four high rolling mill. The surface morphology, oxide scales and metallographic structure after hot rolling were observed using a confocal laser scanning microscope and scanning electron microscope (SEM), respectively. The composition of surface attachments was analyzed with X-ray photoelectron spectroscopy (XPS). The results indicate that the nano-TiO2 lubricating fluid has a better tribological performance. The surface defects on the hot rolled surface could be decreased. The phase composition of the surface still appears as a mixture of ferrite and pearlite. The surface of steel strips is not micro-alloyed with titanium as predicted. Additionally, the grain size of rolled steel strips which were lubricated with the nano-TiO2lubricating fluid decreased by nearly 50%, compared with traditional lubricating fluid. Furthermore, it was found that the thickness of the oxide layers on the surface reduced, whilst the Rockwell hardness of the oxide layers was enhanced as nano-TiO2 lubricating fluid was applied.

AB - Two dimensional (2D)SnO2 nanosheets were synthesized by a substrate-free hydrothermal route using sodium stannate and sodium hydroxide in a mixed solvent of absolute ethanol and deionized water at a lower temperature of 130 degrees C. The characterization results of the morphology, microstructure, and surface properties of the as-prepared products demonstrated that SnO2 nanosheets with a tetragonal rutile structure, were composed of oriented SnO2 nanoparticles with a diameter of 6-12 nm. The X-ray diffraction (XRD) and high-resolution transmission electron microscope (FETEM) results demonstrated that the dominant exposed surface of the SnO2 nanoparticles was (101), but not (110). The growth and formation was supposed to follow the oriented attachment mechanism. The SnO2 nanosheets exhibited an excellent sensing response toward ethylene glycol at a lower optimal operating voltage of 3.4 V. The response to 400 ppm ethylene glycol reaches 395 at 3.4 V. Even under the low concentration of 5, 10, and 20 ppm, the sensor exhibited a high response of 6.9, 7.8, and 12.0 to ethylene glycol, respectively. The response of the SnO2 nanosheets exhibited a linear dependence on the ethylene glycol concentration from 5 to 1000 ppm. The excellent sensing performance was attributed to the present SnO2 nanoparticles with small size close to the Debye length, the larger specific surface, the high-energy exposed facets of the (101) surface, and the synergistic effects of the SnO2 nanoparticles of the nanosheets.

AB - Acute respiratory distress syndrome is an inflammatory disease characterized by dysfunction of pulmonary epithelial and capillary endothelial cells, infiltration of alveolar macrophages and neutrophils, cell apoptosis, necroptosis, NETosis, and fibrosis. Inflammatory responses have key effects on every phase of acute respiratory distress syndrome. The severe inflammatory cascades impaired the regulation of vascular endothelial barrier and vascular permeability. Therefore, understanding the relationship between the molecular regulation of immune cells and the pulmonary microenvironment is critical for disease management. This article reviews the current clinical and basic research on the pathogenesis of acute respiratory distress syndrome, including information on the microenvironment, vascular endothelial barrier and immune mechanisms, to offer a strong foundation for developing therapeutic interventions.

AB - BACKGROUND: B-cell differentiation and B-cell tolerance checkpoints may be different in antiphospholipid syndrome (APS) from systemic lupus erythematosus (SLE) and can help to understand differences between them. Our aim was to define alterations of B-cell subsets in patients with primary APS (pAPS) and to compare them with SLE patients and healthy controls (HC). METHODS: Cross-sectional study including three study groups: 37 patients with pAPS, 11 SLE patients, and 21 age- and gender-matched HC. We determined the frequencies of different B-cell subsets in peripheral blood naive and memory compartments. In addition, we measured serum B cell-activating factor (BAFF) levels and circulating pro-inflammatory cytokines, such as IL-6, by commercial ELISA and CBA, respectively. RESULTS: Patients with pAPS showed a lower percentage of immature and naive B cells than patients with SLE (p = 0.013 and p = 0.010, respectively) and a higher percentage of non-switched memory B cells than patients with SLE (p = 0.001). No differences either in the percentage of switched memory cells or plasma cells were found among the different groups. Serum BAFF levels were higher in SLE patients than in healthy controls and pAPS patients (p = 0.001 and p = 0.017, respectively). A significant increase in the serum BAFF levels was also observed in pAPS patients compared to HC (p = 0.047). Circulating IL-6 levels were higher in SLE and pAPS patients than HC (p = 0.036 and p = 0.048, respectively). A positive correlation was found between serum BAFF and IL-6 levels in patients with SLE but not in pAPS (p = 0.011). CONCLUSIONS: Our characterization of peripheral blood B-cell phenotypes in pAPS demonstrates different frequencies of circulating B cells at different stages of differentiation. These differences in the naive B-cell repertoire could explain the higher number and variety of autoantibodies in SLE patients in comparison to pAPS patients, especially in those with obstetric complications.

AB - Layered double hydroxides (LDHs) have been widely used as an important subset of solid base catalysts. However, developing low-cost, small-sized LDH nanoparticles with enhanced surface catalytic sites remains a challenge. In this work, silica aerogel (SA)-supported, small-sized Mg-Al LDH nanosheets were successfully prepared by one-pot coprecipitation of Mg and Al ions in an alkaline suspension of crushed silica aerogel. The supported LDH nanosheets were uniformly dispersed in the SA substrate with the smallest average radial diameter of 19.2 nm and the thinnest average thickness of 3.2 nm, both dimensions being significantly less than those of the vast majority of LDH nanoparticles reported. The SA/LDH composites also showed large pore volume (up to 1.3 cm3.g) and pore diameter (>9 nm), and therefore allow efficient access of reactants to the edge catalytic sites of LDH nanosheets. In a base-catalyzed Henry reaction of benzaldehyde with nitromethane, the SA/LDH catalysts showed high reactant conversions and favorable stability in 6 successive cycles of reactions. The low cost of the SA carrier and LDH precursors, easy preparation method, and excellent catalytic properties make these SA/LDH composites a competitive example of solid-base catalysts. PMID- 29462940 TI - Is the Definition of Roma an Important Matter? The Parallel Application of Self and External Classification of Ethnicity in a Population-Based Health Interview Survey. AB - The Roma population is typified by a poor and, due to difficulties in ethnicity assessment, poorly documented health status. We aimed to compare the usefulness of self-reporting and observer-reporting in Roma classification for surveys investigating differences between Roma and non-Roma populations. Both self reporting and observer-reporting of Roma ethnicity were applied in a population based health interview survey. A questionnaire was completed by 1849 people aged 18-64 years; this questionnaire provided information on 52 indicators (morbidity, functionality, lifestyle, social capital, accidents, healthcare use) indicators. Multivariate logistic regression models controlling for age, sex, education and employment were used to produce indicators for differences between the self reported Roma (N = 124) and non-Roma (N = 1725) populations, as well as between observer-reported Roma (N = 179) and non-Roma populations (N = 1670). Differences between interviewer-reported and self-reported individuals of Roma ethnicity in statistical inferences were observed for only seven indicators. The self reporting approach was more sensitive for two indicators, and the observer reported assessment for five indicators. Based on our results, the self-reported identity can be considered as a useful approach, and the application of observer reporting cannot considerably increase the usefulness of a survey, because the differences between Roma and non-Roma individuals are much bigger than the differences between indicators produced by self-reported or observer-reported data on individuals of Roma ethnicity. PMID- 29462942 TI - Performance and Fouling Study of Asymmetric PVDF Membrane Applied in the Concentration of Organic Fertilizer by Direct Contact Membrane Distillation (DCMD). AB - This study proposes using membrane distillation (MD) as an alternative to the conventional multi-stage flushing (MSF) process to concentrate a semi-product of organic fertilizer. By applying a unique asymmetric polyvinylidene fluoride (PVDF) membrane, which was specifically designed for MD applications using a nonsolvent thermally induced phase separation (NTIPS) method, the direct contact membrane distillation (DCMD) performance was investigated in terms of its sustainability in permeation flux, fouling resistance, and anti-wetting properties. It was found that the permeation flux increased with increasing flow rate, while the top-surface facing feed mode was the preferred orientation to achieve 25% higher flux than the bottom-surface facing feed mode. Compared to the commercial polytetrafluoroethylene (PTFE) membrane, the asymmetric PVDF membrane exhibited excellent anti-fouling and sustainable flux, with less than 8% flux decline in a 15 h continuous operation, i.e., flux decreased slightly and was maintained as high as 74 kg.m-2.h-1 at 70 degrees C. Meanwhile, the lost flux was easily recovered by clean water rinsing. Overall 2.6 times concentration factor was achieved in 15 h MD operation, with 63.4% water being removed from the fertilizer sample. Further concentration could be achieved to reach the desired industrial standard of 5x concentration factor. PMID- 29462943 TI - Functional Association between Regulatory RNAs and the Annexins. AB - Cells respond to pathophysiological states by activation of stress-induced signalling. Regulatory non-coding microRNAs (miRNAs) often form stable feed forward loops which ensure prolongation of the signal, contributing to sustained activation. Members of the annexin protein family act as sensors for Ca2+, pH, and lipid second messengers, and regulate various signalling pathways. Recently, annexins were reported to participate in feedback loops, suppressing miRNA synthesis and attenuating stress-induced dysregulation of gene expression. They can directly or indirectly associate with RNAs, and are transferred between the cells in exosomes and shed microvesicles. The ability of annexins to recruit other proteins and miRNAs into exosomes implicates them in control of cell-cell interactions, affecting the adaptive responses and remodelling processes during disease. The studies summarized in this Review point to an emerging role of annexins in influencing the synthesis, localisation, and transfer of regulatory RNAs. PMID- 29462944 TI - Multifaceted Mechanisms of Cisplatin Resistance in Long-Term Treated Urothelial Carcinoma Cell Lines. AB - Therapeutic efficacy of cisplatin-based treatment of late stage urothelial carcinoma (UC) is limited by chemoresistance. To elucidate underlying mechanisms and to develop new approaches for overcoming resistance, we generated long-term cisplatin treated (LTT) UC cell lines, characterised their cisplatin response, and determined the expression of molecules involved in cisplatin transport and detoxification, DNA repair, and apoptosis. Inhibitors of metallothioneins and Survivin were applied to investigate their ability to sensitise towards cisplatin. Cell growth, proliferation, and clonogenicity were examined after cisplatin treatment by MTT 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, EdU (5-ethynyl-2'-deoxyuridine) incorporation assay, and Giemsa staining, respectively. Cell cycle distribution and apoptosis were quantified by flow cytometry. mRNA and protein expressions were measured by real-time quantitative (qRT)-PCR, western blot, or immunofluorescence staining. LTTs recovered rapidly from cisplatin stress compared to parental cells. In LTTs, to various extents, cisplatin exporters and metallothioneins were induced, cisplatin adduct levels and DNA damage were decreased, whereas expression of DNA repair factors and specific anti-apoptotic factors was elevated. Pharmacological inhibition of Survivin, but not of metallothioneins, sensitised LTTs to cisplatin, in an additive manner. LTTs minimise cisplatin-induced DNA damage and evade apoptosis by increased expression of anti-apoptotic factors. The observed diversity among the four LTTs highlights the complexity of cisplatin resistance mechanisms even within one tumour entity, explaining heterogeneity in patient responses to chemotherapy. PMID- 29462945 TI - Luminal lncRNAs Regulation by ERalpha-Controlled Enhancers in a Ligand Independent Manner in Breast Cancer Cells. AB - Estrogen receptor-alpha (ERalpha) is a ligand-inducible protein which mediates estrogenic hormones signaling and defines the luminal BC phenotype. Recently, we demonstrated that even in absence of ligands ERalpha (apoERalpha) binds chromatin sites where it regulates transcription of several protein-coding and lncRNA genes. Noteworthy, apoERalpha-regulated lncRNAs marginally overlap estrogen induced transcripts, thus representing a new signature of luminal BC genes. By the analysis of H3K27ac enrichment in hormone-deprived MCF-7 cells, we defined a set of Super Enhancers (SEs) occupied by apoERalpha, including one mapped in proximity of the DSCAM-AS1 lncRNA gene. This represents a paradigm of apoERalpha activity since its expression is largely unaffected by estrogenic treatment, despite the fact that E2 increases ERalpha binding on DSCAM-AS1 promoter. We validated the enrichment of apoERalpha, p300, GATA3, FoxM1 and CTCF at both DSCAM AS1 TSS and at its associated SE by ChIP-qPCR. Furthermore, by analyzing MCF-7 ChIA-PET data and by 3C assays, we confirmed long range chromatin interaction between the SE and the DSCAM-AS1 TSS. Interestingly, CTCF and p300 binding showed an enrichment in hormone-depleted medium and in the presence of ERalpha, elucidating the dynamics of the estrogen-independent regulation of DSCAM-AS1 expression. The analysis of this lncRNA provides a paradigm of transcriptional regulation of a luminal specific apoERalpha regulated lncRNA. PMID- 29462946 TI - A Biochemical Approach to Detect Oxidative Stress in Infertile Women Undergoing Assisted Reproductive Technology Procedures. AB - Oxidative stress plays a major role in critical biological processes in human reproduction. However, a reliable and biologically accurate indicator of this condition does not yet exist. On these bases, the aim of this study was to assess and compare the blood and follicular fluid (FF) redox status of 45 infertile subjects (and 45 age-matched controls) undergoing in vitro fertilization (IVF), and explore possible relationships between the assessed redox parameters and IVF outcomes. Reactive Oxygen Species (ROS) production, assessed by flow cytometry analysis in blood leukocytes and granulosa cells, significantly increased (p < 0.05) in infertile patients. Also, oxidative stress markers-ThioBarbituric Acid Reactive Substances (TBARS) as an index of lipid peroxidation, and Oxygen Radical Absorbance Capacity (ORAC) to account for total antioxidant capacity, both assayed by fluorometric procedures-in blood and FF were significantly (p < 0.001) modified in infertile patients compared to the control group. Moreover, a significant correlation between blood redox markers and FF redox markers was evident. An ORAC/TBARS ratio, defined as the redox index (RI), was obtained in the plasma and FF of the patients and controls. In the patients, the plasma RI was about 3.4-fold (p < 0.0001) lower than the control, and the FF RI was about six-fold (p < 0.0001) lower than the control. Interestingly, both the plasma RI and FF RI results were significantly correlated (p < 0.05) to the considered outcome parameters (metaphase II, fertilization rate, and ongoing pregnancies). Given the reported findings, a strict monitoring of redox parameters in assisted reproductive techniques and infertility management is recommended. PMID- 29462947 TI - Immunogenic Apoptosis as a Novel Tool for Anticancer Vaccine Development. AB - Immunogenic apoptosis, or more appropriately called immunogenic cell death (ICD), is a recently described form of apoptosis induced by a specific set of chemotherapeutic drugs or by physical therapeutic modalities, such as ionizing irradiation and photodynamic therapy. The peculiar characteristic of ICD is the ability to favor recognition and elimination of dying tumor cells by phagocytes in association with the release of pro-inflammatory molecules (such as cytokines and high-mobility group box-1). While in vitro and animal models pointed to ICD as one of the molecular mechanisms mediating the clinical efficacy of some anticancer agents, it is hard to clearly demonstrate its contribution in cancer patients. Clinical evidence suggests that the induction of ICD alone is possibly not sufficient to fully subvert the immunosuppressive tumor microenvironment. However, interesting results from recent studies contemplate the exploitation of ICD for improving the immunogenicity of cancer cells to use them as an antigen cargo in the development of dendritic cell (DC) vaccines. Herein, we discuss the effects of danger signals expressed or released by cancer cells undergoing ICD on the maturation and activation of immature and mature DC, highlighting the potential added value of ICD in adoptive immunotherapy protocols. PMID- 29462949 TI - The Use of Biomass for Electricity Generation: A Scoping Review of Health Effects on Humans in Residential and Occupational Settings. AB - The utilization of biomass for power generation has become more prevalent globally. To survey the status of evidence concerning resulting health impacts and to depict potential research needs, a scoping-review was conducted. Biomass life cycle phases of interest were the conversion and combustion phases. Studies from occupational and residential settings were considered. The scoping review was conducted systematically, comprising an extensive literature search, a guided screening process, in-duplicate data extraction, and critical appraisal. Two reviewers executed most review steps. Nine articles of relevance were identified. In occupational settings of biomass plants, exposure to endotoxins and fungi might be associated with respiratory disorders. An accidental leakage of hydrogen sulfide in biogas plants may lead to fatalities or severe health impacts. Living near biomass power plants (and the accompanied odorous air pollution) may result in an increased risk for several symptoms and odor annoyance, mediated by perception about air pollution or an evaluation of a resulting health risk. The methodological quality of included studies varied a lot. Overall, the body of evidence on the topic is sparse and future high-quality research is strongly recommended. PMID- 29462948 TI - Microfluidic Devices for Drug Delivery Systems and Drug Screening. AB - Microfluidic devices present unique advantages for the development of efficient drug carrier particles, cell-free protein synthesis systems, and rapid techniques for direct drug screening. Compared to bulk methods, by efficiently controlling the geometries of the fabricated chip and the flow rates of multiphase fluids, microfluidic technology enables the generation of highly stable, uniform, monodispersed particles with higher encapsulation efficiency. Since the existing preclinical models are inefficient drug screens for predicting clinical outcomes, microfluidic platforms might offer a more rapid and cost-effective alternative. Compared to 2D cell culture systems and in vivo animal models, microfluidic 3D platforms mimic the in vivo cell systems in a simple, inexpensive manner, which allows high throughput and multiplexed drug screening at the cell, organ, and whole-body levels. In this review, the generation of appropriate drug or gene carriers including different particle types using different configurations of microfluidic devices is highlighted. Additionally, this paper discusses the emergence of fabricated microfluidic cell-free protein synthesis systems for potential use at point of care as well as cell-, organ-, and human-on-a-chip models as smart, sensitive, and reproducible platforms, allowing the investigation of the effects of drugs under conditions imitating the biological system. PMID- 29462950 TI - Microbiome Data Accurately Predicts the Postmortem Interval Using Random Forest Regression Models. AB - Death investigations often include an effort to establish the postmortem interval (PMI) in cases in which the time of death is uncertain. The postmortem interval can lead to the identification of the deceased and the validation of witness statements and suspect alibis. Recent research has demonstrated that microbes provide an accurate clock that starts at death and relies on ecological change in the microbial communities that normally inhabit a body and its surrounding environment. Here, we explore how to build the most robust Random Forest regression models for prediction of PMI by testing models built on different sample types (gravesoil, skin of the torso, skin of the head), gene markers (16S ribosomal RNA (rRNA), 18S rRNA, internal transcribed spacer regions (ITS)), and taxonomic levels (sequence variants, species, genus, etc.). We also tested whether particular suites of indicator microbes were informative across different datasets. Generally, results indicate that the most accurate models for predicting PMI were built using gravesoil and skin data using the 16S rRNA genetic marker at the taxonomic level of phyla. Additionally, several phyla consistently contributed highly to model accuracy and may be candidate indicators of PMI. PMID- 29462951 TI - Ionic Liquid-Promoted Synthesis of Novel Chromone-Pyrimidine Coupled Derivatives, Antimicrobial Analysis, Enzyme Assay, Docking Study and Toxicity Study. AB - Herein, we report an environmentally friendly, rapid, and convenient ionic liquid ([Et3NH][HSO4])-promoted facile synthesis of ethyl 4-(6-substituted-4-oxo-4H chromen-3-yl)-6-methyl-2-thioxo/oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate derivatives 4(a-f) and 4-(6-substituted-4-oxo-4H-chromen-3-yl)-6-methyl-2 thioxo/oxo-1,2,3,4-tetrahydropyrimidine-5- carbohydrazide derivatives 6(a-f). All the synthesized derivatives 4(a-f) and 6(a-f) were evaluated for their in vitro antifungal and antibacterial activity, by method recommended by National Committee for Clinical Laboratory Standards (NCCLS). The compound 6c bearing a fluoro group on the chromone ring and oxygen and a hydrazino group (-NHNH2) on the pyrimidine ring, was found to be the most potent antibacterial compound amongst the synthesized derivatives. The compound 6f bearing a methoxy group ( OCH3) on the chromone ring and sulphur group on the pyrimidine ring, was found to exhibit equipotent antifungal activity when compared with the standard drug miconazole. A D-alanine-D-alanine ligase (DdlB) enzyme assay study and an ergosterol extraction and quantitation assay study were performed to predict the mode of action of the synthesized compounds. A molecular docking study was performed to predict the binding interactions with receptors and mode of action of the synthesized derivatives. Further, analysis of the ADMET parameters for the synthesized compounds has shown that these compounds have good oral drug-like properties and can be developed as oral drug candidates. To establish the antimicrobial selectivity and safety, the most active compounds 6c and 6f were further tested for cytotoxicity against the human cancer cell line HeLa and were found to be non-cytotoxic in nature. An in vivo acute oral toxicity study was also performed for the most active compounds 6c and 6f and the results indicated that the compounds are non-toxic in nature. PMID- 29462952 TI - Impact of Selenium Addition to Animal Feeds on Human Selenium Status in Serbia. AB - Research conducted during the 1980s demonstrated Se deficiency in humans. Increased inclusion of selenium in animal feeds started from the year 2000 onwards. The aim of this study was to estimate the effects of selenium inclusion in animal feeds on human selenium status and dietary habits of the Serbian population related to food of animal origin. Plasma selenium concentration in healthy adult volunteers, including residents of one of the regions with the lowest (Eastern Serbia, n = 60) and of one of the regions with the highest Se serum levels reported in the past (Belgrade, n = 82), was determined by hydride generation atomic absorption spectrometry. Multivariate analysis was employed to determine the correlation between Se plasma levels and dietary intake data derived from food frequency questionnaires and laboratory tests. The mean plasma Se level of the participants was 84.3 +/- 15.9 MUg/L (range: 47.3-132.1 MUg/L), while 46% of participants had plasma Se levels lower than 80 MUg/L. Frequency of meat, egg, and fish consumption was significantly correlated with plasma selenium level (r = 0.437, p = 0.000). Selenium addition to animal feed in the quantity of 0.14 mg/kg contributed to the improvement of human plasma selenium levels by approximately 30 MUg/L. PMID- 29462953 TI - Recent Advances in Active Infrared Thermography for Non-Destructive Testing of Aerospace Components. AB - Active infrared thermography is a fast and accurate non-destructive evaluation technique that is of particular relevance to the aerospace industry for the inspection of aircraft and helicopters' primary and secondary structures, aero engine parts, spacecraft components and its subsystems. This review provides an exhaustive summary of most recent active thermographic methods used for aerospace applications according to their physical principle and thermal excitation sources. Besides traditional optically stimulated thermography, which uses external optical radiation such as flashes, heaters and laser systems, novel hybrid thermographic techniques are also investigated. These include ultrasonic stimulated thermography, which uses ultrasonic waves and the local damage resonance effect to enhance the reliability and sensitivity to micro-cracks, eddy current stimulated thermography, which uses cost-effective eddy current excitation to generate induction heating, and microwave thermography, which uses electromagnetic radiation at the microwave frequency bands to provide rapid detection of cracks and delamination. All these techniques are here analysed and numerous examples are provided for different damage scenarios and aerospace components in order to identify the strength and limitations of each thermographic technique. Moreover, alternative strategies to current external thermal excitation sources, here named as material-based thermography methods, are examined in this paper. These novel thermographic techniques rely on thermoresistive internal heating and offer a fast, low power, accurate and reliable assessment of damage in aerospace composites.

AB - Most early-intervention Autism Spectrum Disorder (ASD) clinical trials are limited by the availability of psychometric technicians who assess each child's abilities before and after therapeutic intervention. If parents could administer regular psychometric evaluations of their children, then the cost of clinical trials will be reduced, enabling longer clinical trials with the larger number of participants. The Autism Treatment Evaluation Checklist (ATEC) was designed nearly two decades ago to provide such a tool, but the norms on the longitudinal changes in ATEC in the "treatment as usual" population were lacking. Here we report the norms of the observational cohort who voluntarily completed ATEC evaluations over the period of four years from 2013 to 2017. PMID- 29462955 TI - Liposomal Formulations for an Efficient Encapsulation of Epigallocatechin-3 gallate: An in- Silico/Experimental Approach. AB - As a part of research project aimed to optimize antioxidant delivery, here we studied the influence of both salts and lipid matrix composition on the interaction of epigallocatechin-3-gallate (EGCG) with bilayer leaflets. Thus, we combined in silico and experimental methods to study the ability of neutral and anionic vesicles to encapsulate EGCG in the presence of Ca2+ and Mg2+ divalent salts. Experimental and in silico results show a very high correlation, thus confirming the efficiency of the developed methodology. In particular, we found out that the presence of calcium ions hinders the insertion of EGCG in the liposome bilayer in both neutral and anionic systems. On the contrary, the presence of MgCl2 improves the insertion degree of EGCG molecules respect to the liposomes without divalent salts. The best and most efficient salt concentration is that corresponding to a 5:1 molar ratio between Mg2+ and EGCG, in both neutral and anionic vesicles. Concerning the lipid matrix composition, the anionic one results in better promotion of the catechin insertion within the bilayer since experimentally we achieved 100% EGCG encapsulation in the lipid carrier in the presence of a 5:1 molar ratio of magnesium. Thus, the combination of this anionic liposomal formulation with magnesium chloride, avoids time-consuming separation steps of unentrapped active principle and appears particularly suitable for EGCG delivery applications.

AB - The synthesis of five novel homodimers is reported based on the anilinoisoquinolinequinone scaffold. In these twin-drug derivatives, two units of the anilinoquinone pharmacophores are linked through a methylene spacer. The formation of dimers was achieved by reaction of isoquinolinequinones with 4, 4' diaminodiphenylmethane via a sequence of two oxidative amination reactions. A preliminary in vitro screening of the homodimers reveals moderate to high cytotoxic activities against MDA-MB-21 breast adenocarcinoma and B16-F10 murine metastatic melanoma cell lines. The asymmetrical homodimer 15 stands out due to its cytotoxic potencies at submicromolar concentrations and high selectivity index (mean IC50 = 0.37 MUM; SI = 6.97) compared to those of etoposide (mean IC50 = 3.67; SI = 0.32) and taxol (mean IC50 = 0.35; SI = 0.91) employed as reference anticancer drugs. PMID- 29462957 TI - An Advanced IoT-based System for Intelligent Energy Management in Buildings. AB - The energy sector is closely interconnected with the building sector and integrated Information and Communication Technologies (ICT) solutions for effective energy management supporting decision-making at building, district and city level are key fundamental elements for making a city Smart. The available systems are designed and intended exclusively for a predefined number of cases and systems without allowing for expansion and interoperability with other applications that is partially due to the lack of semantics. This paper presents an advanced Internet of Things (IoT) based system for intelligent energy management in buildings. A semantic framework is introduced aiming at the unified and standardised modelling of the entities that constitute the building environment. Suitable rules are formed, aiming at the intelligent energy management and the general modus operandi of Smart Building. In this context, an IoT-based system was implemented, which enhances the interactivity of the buildings' energy management systems. The results from its pilot application are presented and discussed. The proposed system extends existing approaches and integrates cross-domain data, such as the building's data (e.g., energy management systems), energy production, energy prices, weather data and end users' behaviour, in order to produce daily and weekly action plans for the energy end-users with actionable personalised information.

AB - Apium graveolens (celery) is an edible and traditionally medicinal plant that is used worldwide, among others for the treatment of hypertension. Combining celery with antihypertensive drugs can affect the pharmacodynamics and pharmacokinetics of the latter drugs. The aim of the study is to assess the effects of administrating the celery extract on captopril pharmacokinetics. Sprague-Dawley strain rats were divided into two groups (n = 6). Group I was given captopril (10 mg/kg Body Weight (BW)) orally, while Group II was pretreated with celery extract orally (40 mg/kg BW) an hour before administration of captopril. The blood samples were withdrawn at various intervals after drug administration. The captopril concentration was determined using liquid chromatography-mass spectrometry (LC-MS/MS) and from the blood data, the values of Ke, Cmax, Tmax, T1/2, and area under the curve (AUC) were calculated. The results showed that oral administration of the celery extract increased Cmax (38.67%), T1/2 (37.84%), and AUC (58.10%) and decreased Ke (27.45%) of captopril in Group II (celery + captopril) compared with Group I (captopril). In conclusion, celery extract can alter the pharmacokinetic of captopril when given in combination. The combination might be beneficial for the treatment of hypertension, as celery causes an increase in the plasma level of captopril, which can enhance its efficacy.

AB - Reported herein is the development of an effective strategy for controlled and efficient Lewis pair polymerization of conjugated polar alkenes, including methyl methacrylate (MMA), n-butyl methacrylate (nBuMA), and gamma-methyl-alpha methylene-gamma-butyrolactone (gammaMMBL), by the utilization of sterically encumbered Al(BHT)2Me (BHT: 2,6-di-tert-butyl-4-methylphenol) as a Lewis acid that shuts down intramolecular backbiting termination. In combination with a selected N-heterocyclic carbene (NHC) as a Lewis base, the polymerization of MMA exhibited activity up to 3000 h-1 TOF and an acceptable initiation efficiency of 60.6%, producing polymers with high molecular weight (Mn up to 130 kg/mol) and extremely narrow dispersity (D = 1.06~1.13). This controlled polymerization with a living characteristic has been evidenced by chain-extension experiments and chain-end analysis, and enabled the synthesis of well-defined diblock copolymers. PMID- 29462961 TI - A Phase I/II Study Targeting Angiogenesis Using Bevacizumab Combined with Chemotherapy and a Histone Deacetylase Inhibitor (Valproic Acid) in Advanced Sarcomas. AB - Epigenetic events and genetic alterations under the control of the tumor microenvironment potentially mediate tumor induced angiogenesis involved in soft tissue sarcoma (STS) metastasis. Addition of antiangiogenic agent, such as bevacizumab, to standard chemotherapy in treatment of sarcoma has been studied in clinical trials, but most of the findings have not supported its use. We hypothesized the existence of an epigenetically mediated "angiogenic switch", and the tumor microenvironment, prevents bevacizumab from truly blocking angiogenesis. The addition of valproic acid (VPA), a weak histone deacetylase inhibitor, and bevacizumab, a monoclonal antibody against vascular endothelial growth factor, together with the cytotoxic effects of gemcitabine and docetaxel, may enhance responses and alter chemoresistance. This was designed as a phase I/II trial with primary endpoints including safety of the treatment combination and tumor response. Unresectable or metastatic sarcoma patients >18 years of age, irrespective of number of prior treatments, received VPA 40 mg/kg orally for 5 days prior to day 1, bevacizumab at 15 mg/kg IV on day 1, gemcitabine 900 mg/m2 (day 1, day 8), and docetaxel 75 mg/m2 (day 8). Cycles were of 28 day duration. Bevacizumab and VPA were continued as maintenance after 6 cycles, until disease progression. A standard 3 + 3 phase I dose de-escalation design was utilized to evaluate safety. Gain of function p53 gene mutation testing was performed on available archival tissue specimens. A total of 46 patients (30 female, 16 male) with median age of 60 (range 24-81) years were enrolled; 34 (73.9%) patients received prior chemotherapy, 14 (30%) of which received prior gemcitabine and docetaxel. Patients received a median of 5.5 cycles (range 0-24 of treatment (min 0, one patient died prior to completing the first cycle; max: 24, one patient received 6 cycles and 18 maintenance cycles before progressing). Seventeen patients underwent dose reduction, of which VPA was reduced in 6 patients. Forty one patients were evaluable for response. There was a confirmed complete response in 1 (epithelioid sarcoma), and a partial response (PR) in 6 (1 carcinosarcoma, 2 extrauterine leiomyosarcoma (LMS), 2 undifferentiated pleomorphic sarcoma, and 1 uterine LMS) patients. Stable disease (SD) was seen in 21 patients for at least 2 months. One subject with prior gemcitabine and docetaxel had PR, and 7 had SD. Median progression-free survival (PFS) was 5.7 months (95% CI: 2.1-8.0), and overall survival (OS) was 12.9 months (95% CI: 8.3-14.5). Three patients died due to tumor progression while on the study. The combination of VPA, bevacizumab, gemcitabine, and docetaxel appears to be moderately safe and well tolerated. Given that there are very limited options for patients with relapsed refractory STS, this drug combination may be an important therapy to consider. This combination treatment deserves further investigation in epithelioid and carcinosarcoma subtypes.

AB - The launch of the Chinese Gaofen-3 (GF-3) satellite will provide enough synthetic aperture radar (SAR) images with different imaging modes for land cover classification and other potential usages in the next few years. This paper aims to propose an efficient and practical classification framework for a GF-3 polarimetric SAR (PolSAR) image. The proposed classification framework consists of four simple parts including polarimetric feature extraction and stacking, the initial classification via XGBoost, superpixels generation by statistical region merging (SRM) based on Pauli RGB image, and a post-processing step to determine the label of a superpixel by modified majority voting. Fast initial classification via XGBoost and the incorporation of spatial information via a post-processing step through superpixel-based modified majority voting would potentially make the method efficient in practical use. Preliminary experimental results on real GF-3 PolSAR images and the AIRSAR Flevoland data set validate the efficacy and efficiency of the proposed classification framework. The results demonstrate that the quality of GF-3 PolSAR data is adequate enough for classification purpose. The results also show that the incorporation of spatial information is important for overall performance improvement. PMID- 29462960 TI - The Role of Wnt Signal in Glioblastoma Development and Progression: A Possible New Pharmacological Target for the Therapy of This Tumor. AB - Wnt is a complex signaling pathway involved in the regulation of crucial biological functions such as development, proliferation, differentiation and migration of cells, mainly stem cells, which are virtually present in all embryonic and adult tissues. Conversely, dysregulation of Wnt signal is implicated in development/progression/invasiveness of different kinds of tumors, wherein a certain number of multipotent cells, namely "cancer stem cells", are characterized by high self-renewal and aggressiveness. Hence, the pharmacological modulation of Wnt pathway could be of particular interest, especially in tumors for which the current standard therapy results to be unsuccessful. This might be the case of glioblastoma multiforme (GBM), one of the most lethal, aggressive and recurrent brain cancers, probably due to the presence of highly malignant GBM stem cells (GSCs) as well as to a dysregulation of Wnt system. By examining the most recent literature, here we point out several factors in the Wnt pathway that are altered in human GBM and derived GSCs, as well as new molecular strategies or experimental drugs able to modulate/inhibit aberrant Wnt signal. Altogether, these aspects serve to emphasize the existence of alternative pharmacological targets that may be useful to develop novel therapies for GBM. PMID- 29462963 TI - Secreted and Tissue miRNAs as Diagnosis Biomarkers of Malignant Pleural Mesothelioma. AB - Malignant pleural mesothelioma (MPM) is a rare but aggressive tumor that originates in the pleura, is diagnosed in advanced stages and has a poor prognosis. Accurate diagnosis of MPM is often difficult and complex, and the gold standard diagnosis test is based on qualitative analysis of markers in pleural tissue by immunohistochemical staining. Therefore, it is necessary to develop quantitative and non-subjective alternative diagnostic tools. MicroRNAs are non coding RNAs that regulate essential cellular mechanisms at the post transcriptional level. Recent evidence indicates that miRNA expression in tissue and body fluids is aberrant in various tumors, revealing miRNAs as promising diagnostic biomarkers. This review summarizes evidence regarding secreted and tissue miRNAs as biomarkers of MPM and the biological characteristics associated with their potential diagnostic value. In addition to studies regarding miRNAs with potential diagnostic value for MPM, studies that aimed to identify the miRNAs involved in molecular mechanisms associated with MPM development are described with an emphasis on relevant aspects of the experimental designs that may influence the accuracy, consistency and real diagnostic value of currently reported data. PMID- 29462964 TI - Behavior of the E-E' Bonds (E, E' = S and Se) in Glutathione Disulfide and Derivatives Elucidated by Quantum Chemical Calculations with the Quantum Theory of Atoms-in-Molecules Approach. AB - The nature of the E-E' bonds (E, E' = S and Se) in glutathione disulfide (1) and derivatives 2-3, respectively, was elucidated by applying quantum theory of atoms in-molecules (QTAIM) dual functional analysis (QTAIM-DFA), to clarify the basic contribution of E-E' in the biological redox process, such as the glutathione peroxidase process. Five most stable conformers a-e were obtained, after applying the Monte-Carlo method then structural optimizations. In QTAIM-DFA, total electron energy densities Hb(rc) are plotted versus Hb(rc) - Vb(rc)/2 at bond critical points (BCPs), where Vb(rc) are potential energy densities at BCPs. Data from the fully optimized structures correspond to the static nature. Those containing perturbed structures around the fully optimized one in the plot represent the dynamic nature of interactions. The behavior of E-E' was examined carefully. Whereas E-E' in 1a-3e were all predicted to have the weak covalent nature of the shared shell interactions, two different types of S-S were detected in 1, depending on the conformational properties. Contributions from the intramolecular non-covalent interactions to stabilize the conformers were evaluated. An inverse relationship was observed between the stability of a conformer and the strength of E-E' in the conformer, of which reason was discussed. PMID- 29462965 TI - Patterns of Protein Food Intake Are Associated with Nutrient Adequacy in the General French Adult Population. AB - Protein food intake appears to partially structure dietary patterns, as most current emergent diets (e.g., vegetarian and flexitarian) can be described according to their levels of specific protein sources. However, few data are available on dietary protein patterns in the general population and their association with nutrient adequacy. Based on protein food intake data concerning 1678 adults from a representative French national dietary survey, and non negative-matrix factorization followed by cluster analysis, we were able to identify distinctive dietary protein patterns and compare their nutrient adequacy (using PANDiet probabilistic scoring). The findings revealed eight patterns that clearly discriminate protein intakes and were characterized by the intakes of one or more specific protein foods: 'Processed meat', 'Poultry', 'Pork', 'Traditional', 'Milk', 'Take-away', 'Beef' and 'Fish'. 'Fish eaters' and 'Milk drinkers' had the highest overall nutrient adequacy, whereas that of 'Pork' and 'Take-away eaters' was the lowest. Nutrient adequacy could often be accounted for by the characteristics of the food contributing to protein intake: 'Meat eaters' had high probability of adequacy for iron and zinc, for example. We concluded that protein patterns constitute strong elements in the background structure of the dietary intake and are associated with the nutrient profile that they convey. PMID- 29462966 TI - Optimal Scheduling and Fair Service Policy for STDMA in Underwater Networks with Acoustic Communications. AB - In this work, a multi-hop string network with a single sink node is analyzed. A periodic optimal scheduling for TDMA operation that considers the characteristic long propagation delay of the underwater acoustic channel is presented. This planning of transmissions is obtained with the help of a new geometrical method based on a 2D lattice in the space-time domain. In order to evaluate the performance of this optimal scheduling, two service policies have been compared: FIFO and Round-Robin. Simulation results, including achievable throughput, packet delay, and queue length, are shown. The network fairness has also been quantified with the Gini index. PMID- 29462968 TI - Feature-Level Fusion of Surface Electromyography for Activity Monitoring. AB - Surface electromyography (sEMG) signals are commonly used in activity monitoring and rehabilitation applications as they reflect effectively the motor intentions of users. However, real-time sEMG signals are non-stationary and vary to a large extent within the time frame of signals. Although previous studies have focused on the issues, their results have not been satisfactory. Therefore, we present a new method of conducting feature-level fusion to obtain a new feature space for sEMG signals. Eight activities of daily life (ADLs), including falls, were performed to obtain raw data from EMG signals from the lower limb. A feature set combining the time domain, time-frequency domain, and entropy domain was applied to the raw data to establish an initial feature space. A new projection method, the weighting genetic algorithm for GCCA (WGA-GCCA), was introduced to obtain the final feature space. Different tests were carried out to evaluate the performance of the new feature space. The new feature space created with the WGA-GCCA effectively reduced the dimensions and selected the best feature vectors dynamically while improving monotonicity. The Davies-Bouldin index (DBI) based on fuzzy c-means algorithms of the space obtained the lowest value compared with several fusion methods. It also achieved the highest accuracy when applied to support vector machine classifier. PMID- 29462967 TI - Overexpression of Receptor Tyrosine Kinase EphB4 Triggers Tumor Growth and Hypoxia in A375 Melanoma Xenografts: Insights from Multitracer Small Animal Imaging Experiments. AB - Experimental evidence has associated receptor tyrosine kinase EphB4 with tumor angiogenesis also in malignant melanoma. Considering the limited in vivo data available, we have conducted a systematic multitracer and multimodal imaging investigation in EphB4-overexpressing and mock-transfected A375 melanoma xenografts. Tumor growth, perfusion, and hypoxia were investigated by positron emission tomography. Vascularization was investigated by fluorescence imaging in vivo and ex vivo. The approach was completed by magnetic resonance imaging, radioluminography ex vivo, and immunohistochemical staining for blood and lymph vessel markers. Results revealed EphB4 to be a positive regulator of A375 melanoma growth, but a negative regulator of tumor vascularization. Resulting in increased hypoxia, this physiological characteristic is considered as highly unfavorable for melanoma prognosis and therapy outcome. Lymphangiogenesis, by contrast, was not influenced by EphB4 overexpression. In order to distinguish between EphB4 forward and EphrinB2, the natural EphB4 ligand, reverse signaling a specific EphB4 kinase inhibitor was applied. Blocking experiments show EphrinB2 reverse signaling rather than EphB4 forward signaling to be responsible for the observed effects. In conclusion, functional expression of EphB4 is considered a promising differentiating characteristic, preferentially determined by non invasive in vivo imaging, which may improve personalized theranostics of malignant melanoma. PMID- 29462969 TI - Milk: An Effective Recovery Drink for Female Athletes. AB - Milk has become a popular post-exercise recovery drink. Yet the evidence for its use in this regard comes from a limited number of investigations utilising very specific exercise protocols, and mostly with male participants. Therefore, the aim of this study was to investigate the effects of post-exercise milk consumption on recovery from a sprinting and jumping protocol in female team sport athletes. Eighteen females participated in an independent-groups design. Upon completion of the protocol participants consumed 500 mL of milk (MILK) or 500 mL of an energy-matched carbohydrate (CHO) drink. Muscle function (peak torque, rate of force development (RFD), countermovement jump (CMJ), reactive strength index (RSI), sprint performance), muscle soreness and tiredness, symptoms of stress, serum creatine kinase (CK) and high-sensitivity C-reactive protein (hsCRP) were determined pre- and 24 h, 48 h and 72 h post-exercise. MILK had a very likely beneficial effect in attenuating losses in peak torque (180?/s) from baseline to 72 h (0.0 +/- 10.0% vs. -8.7 +/- 3.7%, MILK v CHO), and countermovement jump (-1.1 +/- 5.2% vs. -10.4 +/- 6.7%) and symptoms of stress ( 13.5 +/- 7.4% vs. -18.7 +/- 11.0%) from baseline to 24 h. MILK had a likely beneficial effect and a possibly beneficial effect on other peak torque measures and 5 m sprint performance at other timepoints but had an unclear effect on 10 and 20 m sprint performance, RSI, muscle soreness and tiredness, CK and hsCRP. In conclusion, consumption of 500 mL milk attenuated losses in muscle function following repeated sprinting and jumping and thus may be a valuable recovery intervention for female team-sport athletes following this type of exercise. PMID- 29462970 TI - Approaches for Reducing the Risk of Early-Life Iron Deficiency-Induced Brain Dysfunction in Children. AB - Iron deficiency is the most common micronutrient deficiency in the world. Women of reproductive age and young children are particularly vulnerable. Iron deficiency in late prenatal and early postnatal periods can lead to long-term neurobehavioral deficits, despite iron treatment. This may occur because screening and treatment of iron deficiency in children is currently focused on detection of anemia and not neurodevelopment. Anemia is the end-stage state of iron deficiency. The brain becomes iron deficient before the onset of anemia due to prioritization of the available iron to the red blood cells (RBCs) over other organs. Brain iron deficiency, independent of anemia, is responsible for the adverse neurological effects. Early diagnosis and treatment of impending brain dysfunction in the pre-anemic stage is necessary to prevent neurological deficits. The currently available hematological indices are not sensitive biomarkers of brain iron deficiency and dysfunction. Studies in non-human primate models suggest that serum proteomic and metabolomic analyses may be superior for this purpose. Maternal iron supplementation, delayed clamping or milking of the umbilical cord, and early iron supplementation improve the iron status of at-risk infants. Whether these strategies prevent iron deficiency-induced brain dysfunction has yet to be determined. The potential for oxidant stress, altered gastrointestinal microbiome and other adverse effects associated with iron supplementation cautions against indiscriminate iron supplementation of children in malaria-endemic regions and iron-sufficient populations. PMID- 29462971 TI - Species C Rotaviruses in Children with Diarrhea in India, 2010-2013: A Potentially Neglected Cause of Acute Gastroenteritis. AB - All over the world, children and adults are severely affected by acute gastroenteritis, caused by one of the emerging enteric pathogens, rotavirus C (RVC). At present, no extensive surveillance program is running for RVC in India, and its prevalence is largely unknown except cases of local outbreaks. Here, we intended to detect the presence of RVC in diarrheic children visiting or admitted to hospitals in Haldwani (state of Uttarakhand, India), a city located in the foothills of the Himalayas. During 2010-2013, we screened 119 samples for RVC by an RVC VP6 gene-specific RT-PCR. Of these, 38 (31.93%) were found positive, which is higher than the incidence rates reported so far from India. The phylogenetic analysis of the derived nucleotide sequences from one of the human RVC (HuRVC) isolates, designated as HuRVC/H28/2013/India, showed that the study isolate belongs to genotype I2, P2 and E2 for RVC structural genes 6 and 4 (VP6, and VP4) and non-structural gene 4 (NSP4), respectively. Furthermore, the VP6 gene of HuRVC/H28/2013/India shows the highest similarity to a recently-reported human like porcine RVC (PoRVC/ASM140/2013/India, KT932963) from India suggesting zoonotic transmission. We also report a full-length NSP4 gene sequence of human RVC from India. Under the One-health platforms there is a need to launch combined human and animal RVC surveillance programs for a better understanding of the epidemiology of RVC infections and for implementing control strategies.Reoviridae, possess 11 double-stranded segments of RNA that encode six structural viral proteins (VP1, VP2, VP3, VP4, VP6, VP7) and five/six non structural proteins (NSP1-NSP5/6) [7]. Based on the antigenic properties of the major inner capsid protein (VP6), RVs are subdivided into eight well characterized species (A-H) and two putative species viz. I and J [8-10]. Humans and other mammalian species are affected by species A, B, C and H rotaviruses and birds by species D, F and G, and species E has been reported exclusively in pigs [7,8,11-17]. The newly-proposed species I is reported in dogs [18] and cats [19], whereas species J is found in bats [10]. PMID- 29462972 TI - Food-grade Encapsulation Systems for (-)-Epigallocatechin Gallate. AB - (-)-Epigallocatechin gallate (EGCG) has attracted significant research interest due to its health-promoting effects such as antioxidation, anti-inflammation and anti-cancer activities. However, its instability and poor bioavailability have largely limited its efficacy and application. Food-grade materials such as proteins, carbohydrates and lipids show biodegradability, biocompatibility and biofunctionality properties. Food-grade encapsulation systems are usually used to improve the bioavailability of EGCG. In the present paper, we provide an overview of materials and techniques used in encapsulating EGCG, in which the adsorption mechanisms of food-grade systems during in vitro digestion are reviewed. Moreover, the potential challenges and future work using food-grade encapsulates for delivering EGCG are also discussed. PMID- 29462973 TI - The Nordic Prudent Diet Reduces Risk of Cognitive Decline in the Swedish Older Adults: A Population-Based Cohort Study. AB - Appropriate dietary pattern for preserving cognitive function in northern Europe remains unknown. We aimed to identify a Nordic dietary pattern index associated with slower cognitive decline compared to the Mediterranean-DASH Intervention for Neurodegenerative Delay, Mediterranean Diet, Dietary Approaches to Stop Hypertension, and Baltic Sea Diet indices. A total of 2223 dementia-free adults aged >=60 were followed for 6 years. Mini-Mental State Examination was administrated at baseline and follow-ups. Dietary intake was assessed by 98-item food frequency questionnaire, and the Nordic Prudent Dietary Pattern (NPDP) was identified. Data were analysed using mixed-effects and parametric survival models and receiver operating characteristic curves with adjustment for potential confounders. Moderate (beta = 0.139, 95% CI 0.077-0.201) and high adherence (beta = 0.238, 95% CI 0.175-0.300) to NPDP were associated with less cognitive decline compared to other four indices. High adherence to NPDP was also associated with the lowest risk of MMSE decline to <=24 (HR = 0.176, 95% CI 0.080-0.386) and had the greatest ability to predict such decline (area under the curve = 0.70). Moderate-to-high adherence to the NPDP may predict a better-preserved cognitive function among older adults in Nordic countries. Regional dietary habits should be considered in developing dietary guidelines for the prevention of cognitive impairment and dementia. PMID- 29462974 TI - Inadequate Iodine Intake in Population Groups Defined by Age, Life Stage and Vegetarian Dietary Practice in a Norwegian Convenience Sample. AB - Inadequate iodine intake has been identified in populations considered iodine replete for decades. The objective of the current study is to evaluate urinary iodine concentration (UIC) and the probability of adequate iodine intake in subgroups of the Norwegian population defined by age, life stage and vegetarian dietary practice. In a cross-sectional survey, we assessed the probability of adequate iodine intake by two 24-h food diaries and UIC from two fasting morning spot urine samples in 276 participants. The participants included children (n = 47), adolescents (n = 46), adults (n = 71), the elderly (n = 23), pregnant women (n = 45), ovo-lacto vegetarians (n = 25), and vegans (n = 19). In all participants combined, the median (95% CI) UIC was 101 (90, 110) ug/L, median (25th, 75th percentile) calculated iodine intake was 112 (77, 175) ug/day and median (25th, 75th percentile) estimated usual iodine intake was 101 (75, 150) ug/day. According to WHOs criteria for evaluation of median UIC, iodine intake was inadequate in the elderly, pregnant women, vegans and non-pregnant women of childbearing age. Children had the highest (82%) and vegans the lowest (14%) probability of adequate iodine intake according to reported food and supplement intakes. This study confirms the need for monitoring iodine intake and status in nationally representative study samples in Norway. PMID- 29462975 TI - Evaluating the Influence of Chromatic and Luminance Stimuli on SSVEPs from Behind the-Ears and Occipital Areas. AB - This work presents a study of chromatic and luminance stimuli in low-, medium-, and high-frequency stimulation to evoke steady-state visual evoked potential (SSVEP) in the behind-the-ears area. Twelve healthy subjects participated in this study. The electroencephalogram (EEG) was measured on occipital (Oz) and left and right temporal (TP9 and TP10) areas. The SSVEP was evaluated in terms of amplitude, signal-to-noise ratio (SNR), and detection accuracy using power spectral density analysis (PSDA), canonical correlation analysis (CCA), and temporally local multivariate synchronization index (TMSI) methods. It was found that stimuli based on suitable color and luminance elicited stronger SSVEP in the behind-the-ears area, and that the response of the SSVEP was related to the flickering frequency and the color of the stimuli. Thus, green-red stimulus elicited the highest SSVEP in medium-frequency range, and green-blue stimulus elicited the highest SSVEP in high-frequency range, reaching detection accuracy rates higher than 80%. These findings will aid in the development of more comfortable, accurate and stable BCIs with electrodes positioned on the behind the-ears (hairless) areas. PMID- 29462977 TI - Efficiency of Osmotic Dehydration of Apples in Polyols Solutions. AB - The present study aimed to evaluate the influence of selected compounds from the polyol group, as well as other saccharides, on the osmotic dehydration process of apples. The following alternative solutions were examined: erythritol, xylitol, maltitol, inulin and oligofructose. Efficiency of the osmotic dehydration process was evaluated based on the kinetics of the process, and through comparison of the results obtained during the application of a sucrose solution. This innovative research utilizes alternative solutions in osmotic pretreatment, which until now, have not been commonly used in fruit processing by researchers worldwide. Results indicate that erythritol and xylitol show stronger or similar efficiency to sucrose; however, the use of inulin, as well as oligofructose, was not satisfactory due to the insufficient, small osmotic driving forces of the process, and the low values of mass transfer parameters. PMID- 29462976 TI - A Theoretical and Empirical Linkage between Road Accidents and Binge Eating Behaviors in Adolescence. AB - This study aimed at identifying specific clusters of maladaptive emotional behavioral symptoms in adolescent victims of motorbike collisions considering their scores on alexithymia and impulsivity in addition to examining the prevalence of clinical binge eating behaviors (respectively through the Youth Self-Report (YSR), Toronto Alexithymia Scale-20 (TAS-20), Barratt Impulsiveness Scale-11 (BIS-11), and Binge Eating Scale (BES)). Emotional-behavioral profiles, difficulties in identifying and describing feelings, impulsivity, and binge eating behaviors have been assessed in 159 adolescents addressing emergency departments following motorbike collisions. Our results showed a cluster of adolescents with clinical binge eating behaviors, high rates of motorbike accidents, and high levels of internalizing and externalizing problems, alexithymia, and impulsivity (23.3% of the sample); a second cluster of adolescents with clinical binge eating behaviors, a moderate number of collisions, and moderate levels of emotional and behavioral problems on the above four dimensions (25.8% of the sample); and a third cluster of youth without clinical binge eating behaviors, with a moderate number of accidents, and with low scores on the four dimensions (50.9% of the sample). Adolescents of Cluster 1 showed a higher likelihood to be involved in motorbike collisions than the youth in Clusters 2 and 3 (p < 0.0001). We suggest that adolescents' motor collisions could be associated with their difficulties in emotion regulation and with their impaired psychological profiles, which could also underpin their disordered eating. The identification of specific clusters of psychopathological symptoms among this population could be useful for the construction of prevention and intervention programs aimed at reducing motor collision recidivism and alleviating co-occurring psychopathologies. PMID- 29462978 TI - Impact of Western and Mediterranean Diets and Vitamin D on Muscle Fibers of Sedentary Rats. AB - BACKGROUND: The metabolic syndrome is associated with sarcopenia. Decreased serum levels of Vitamin D (VitD) and insulin-like growth factor (IGF)-1 and their mutual relationship were also reported. We aimed to evaluate whether different dietary profiles, containing or not VitD, may exert different effects on muscle molecular morphology. METHODS: Twenty-eight male rats were fed for 10 weeks in order to detect early defects induced by different dietary regimens: regular diet (R); regular diet with vitamin D supplementation (R-DS) and regular diet with vitamin D restriction (R-DR); high-fat butter-based diets (HFB-DS and HFB-DR) with 41% energy from fat; high-fat extra-virgin olive oil-based diets (HFEVO-DS and HFEVO-DR) with 41% energy from fat. IL-1beta, insulin-like growth factor (IGF)1, Dickkopf-1 (DKK-1), and VitD-receptor (VDR) expressions were evaluated by immunohistochemistry. Muscle fiber perimeter was measured by histology and morphometric analysis. RESULTS: The muscle fibers of the HEVO-DS rats were hypertrophic, comparable to those of the R-DS rats. An inverse correlation existed between the dietary fat content and the perimeter of the muscle fibers (p < 0.01). In the HFB-DR rats, the muscle fibers appeared hypotrophic with an increase of IL-1beta and a dramatic decrease of IGF-1 expression. CONCLUSIONS: High-fat western diet could impair muscle metabolism and lay the ground for subsequent muscle damage. VitD associated with a Mediterranean diet showed trophic action on the muscle fibers. PMID- 29462979 TI - Mindfulness Is Associated with the Metabolic Syndrome among Individuals with a Depressive Symptomatology. AB - The Metabolic Syndrome (MetS) is a major public health burden. Dispositional mindfulness has recently been associated with eating disorders, being overweight, and could therefore be associated with the MetS. We aimed to examine in a cross sectional design the relationship between mindfulness, the MetS, and its risk factors in a large sample of the adult general population and the influence of depressive symptomatology on this association. Adults participating in the NutriNet-Sante study who had completed the Five Facets Mindfulness Questionnaire and attended a clinical and biological examination were available for inclusion. Multivariable logistic regression models adjusted for socio-demographic and lifestyle factors were performed. A total of 17,490 individuals were included. Among individuals with a depressive symptomatology, those with higher mindfulness were less likely to have a MetS (OR: 0.73, 95% CI: 0.57-0.93), a high waist circumference, a low HDL-cholesterol level and an elevated fasting blood glucose level (all p <0.05). In those without depressive symptomatology, individuals with higher mindfulness were less likely to have a high waist circumference (p <0.01). In conclusion, higher mindfulness was associated with lower odds of developing a MetS only among individuals with a depressive symptomatology. PMID- 29462980 TI - Characterization of the Venom of C. d. cumanesis of Colombia: Proteomic Analysis and Antivenomic Study. AB - The Colombian rattlesnake Crotalus durissus cumanensis is distributed in three geographic zones of the country: the Atlantic Coast, the upper valley of the Magdalena River, and the eastern plains of the Colombian Orinoquia. Its venom induces neurological symptoms, such as eyelid ptosis, myasthenic facies, and paralysis of the respiratory muscles, which can lead to death. Identification and analysis of C. d. cumanensis showed nine groups of proteins responsible for the neurotoxic effect, of which the crotoxin complex was the most abundant (64.71%). Immunorecognition tests of C. d. cumanensis showed that the use of a commercial antivenom manufactured in Mexico resulted in immunoreactivity. PMID- 29462981 TI - Sensor-Based Assessment of Soil Salinity during the First Years of Transition from Flood to Sprinkler Irrigation. AB - A key issue for agriculture in irrigated arid lands is the control of soil salinity, and this is one of the goals for irrigated districts when changing from flood to sprinkling irrigation. We combined soil sampling, proximal electromagnetic induction, and satellite data to appraise how soil salinity and its distribution along a previously flood-irrigated field evolved after its transformation to sprinkling. We also show that the relationship between NDVI (normalized difference vegetation index) and ECe (electrical conductivity of the soil saturation extracts) mimics the production function between yield and soil salinity. Under sprinkling, the field had a double crop of barley and then sunflower in 2009 and 2011. In both years, about 50% of the soil of the entire studied field-45 ha-had ECe < 8 dS m-1, i.e., allowing barley cultivation, while the percent of surface having ECe >= 16 dS m-1 increased from 8.4% in 2009 to 13.7% in 2011. Our methodology may help monitor the soil salinity oscillations associated with irrigation management. After quantifying and mapping the soil salinity in 2009 and 2011, we show that barley was stunted in places of the field where salinity was higher. Additionally, the areas of salinity persisted after the subsequent alfalfa cropping in 2013. Application of differential doses of water to the saline patches is a viable method to optimize irrigation water distribution and lessen soil salinity in sprinkler-irrigated agriculture. PMID- 29462982 TI - Fusarium graminearum in Stored Wheat: Use of CO2 Production to Quantify Dry Matter Losses and Relate This to Relative Risks of Zearalenone Contamination under Interacting Environmental Conditions. AB - Zearalenone (ZEN) contamination from Fusarium graminearum colonization is particularly important in food and feed wheat, especially during post-harvest storage with legislative limits for both food and feed grain. Indicators of the relative risk from exceeding these limits would be useful. We examined the effect of different water activities (aw; 0.95-0.90) and temperature (10-25 degrees C) in naturally contaminated and irradiated wheat grain, both inoculated with F. graminearum and stored for 15 days on (a) respiration rate; (b) dry matter losses (DML); (c) ZEN production and (d) relationship between DML and ZEN contamination relative to the EU legislative limits. Gas Chromatography was used to measure the temporal respiration rates and the total accumulated CO2 production. There was an increase in temporal CO2 production rates in wetter and warmer conditions in all treatments, with the highest respiration in the 25 degrees C * 0.95 aw treatments + F. graminearum inoculation. This was reflected in the total accumulated CO2 in the treatments. The maximum DMLs were in the 0.95 aw/20-25 degrees C treatments and at 10 degrees C/0.95 aw. The DMLs were modelled to produce contour maps of the environmental conditions resulting in maximum/minimum losses. Contamination with ZEN/ZEN-related compounds were quantified. Maximum production was at 25 degrees C/0.95-0.93 aw and 20 degrees C/0.95 aw. ZEN contamination levels plotted against DMLs for all the treatments showed that at ca <1.0% DML, there was a low risk of ZEN contamination exceeding EU legislative limits, while at >1.0% DML, the risk was high. This type of data is important in building a database for the development of a post-harvest decision support system for relative risks of different mycotoxins.

Both represent emerging viruses in Europe with potential to cause neuroinvasive disease in humans. This study investigates the seroprevalence of serum neutralizing antibodies to WNV and to USUV in birds and in horses in Poland. Antibodies against WNV and USUV were detected in 5 (35.7%) and in 1 (7.14%) of 14 birds and in 62 (15.08%) and in 115 (27.98%) of 411 horses, respectively. Twenty-one WNV serologically positive horses (33.87%) and 67 USUV serologically positive horses (58.26%) did not travel outside Polish borders. Given the high abundance of potentially competent mosquito species in Poland, high populations of horses and different bird species, our findings highlight implementation of active control programs, including monitoring of geographic spread and dynamics of WNV and USUV transmission in both primary and accidental hosts. It is also important to improve public health awareness about the disease these viruses may cause.

AB - Platelet activation contributes to normal haemostasis but also to pathologic conditions like stroke and cardiac infarction. Signalling by cGMP and cAMP inhibit platelet activation and are therefore attractive targets for thrombosis prevention. However, extensive cross-talk between the cGMP and cAMP signalling pathways in multiple tissues complicates the selective targeting of their activities. We have used mathematical modelling based on experimental data from the literature to quantify the steady state behaviour of nitric oxide (NO)/cGMP/cAMP signalling in platelets. The analysis provides an assessment of NO induced cGMP synthesis and PKG activation as well as cGMP-mediated cAMP and PKA activation though modulation of phosphodiesterase (PDE2 and 3) activities. Both one- and two-compartment models of platelet cyclic nucleotide signalling are presented. The models provide new insight for understanding how NO signalling to cGMP and indirectly cAMP, can inhibit platelet shape-change, the initial step of platelet activation. Only the two-compartment models could account for the experimental observation that NO-mediated PKA activation can occur when the bulk platelet cAMP level is unchanged. The models revealed also a potential for hierarchical interplay between the different platelet phosphodiesterases. Specifically, the models predict, unexpectedly, a strong effect of pharmacological inhibitors of cGMP-specific PDE5 on the cGMP/cAMP cross-talk. This may explain the successful use of weak PDE5-inhibitors, such as dipyridamole, in anti-platelet therapy. In conclusion, increased NO signalling or PDE5 inhibition are attractive ways of increasing cGMP-cAMP cross-talk selectively in platelets. PMID- 29462985 TI - Melatonin Regulates the Synthesis of Steroid Hormones on Male Reproduction: A Review. AB - Melatonin is a ubiquitous molecule and exhibits different effects in long-day and short-day breeding animals. Testosterone, the main resource of androgens in the testis, is produced by Leydig cells but regulated mainly by cytokine secreted by Sertoli cells. Melatonin acts as a local modulator of the endocrine activity in Leydig cells. In Sertoli cells, melatonin influences cellular proliferation and energy metabolism and, consequently, can regulate steroidogenesis. These suggest melatonin as a key player in the regulation of steroidogenesis. However, the melatonin-induced regulation of steroid hormones may differ among species, and the literature data indicate that melatonin has important effects on steroidogenesis and male reproduction. PMID- 29462986 TI - I Can Stand Learning: A Controlled Pilot Intervention Study on the Effects of Increased Standing Time on Cognitive Function in Primary School Children. AB - Sedentarism is considered an independent cardiovascular risk factor. Thus, the present study investigated the effects of employing standing desks in classrooms on cognitive function. The intervention class (IG; n = 19) was supplied with standing desks and balance pads for 11 weeks. The control class (CG; n = 19) received lessons as usual. Standing time was assessed objectively (accelerometers) and subjectively (self-report sheets, external classroom observers). The impact of standing on the digit span task and Eriksen flanker task was analysed. The standing time of the IG was higher during the school day in comparison to the CG (lesson: p = 0.004; break: p = 0.003). The intra-class correlation coefficient between self-reports and external observation was high (ICC = 0.94). The IG improved slightly on the Digit Span Task compared to CG. Employing standing desks for at least 1 h per school day serves as a feasible and effective opportunity to improve cognitive function. PMID- 29462987 TI - Mechanisms of Phosphorus Removal by Recycled Crushed Concrete. AB - Due to urbanisation, there are large amounts of waste concrete, particularly in rapidly industrialising countries. Currently, demolished concrete is mainly recycled as aggregate for reconstruction. This study has shown that larger sizes (2-5 mm) of recycled concrete aggregate (RCA) removed more than 90% of P from effluent when at pH 5. Analysis of the data, using equilibrium models, indicated a best fit with the Langmuir which predicated an adsorption capacity of 6.88 mg/g. Kinetic analysis indicated the equilibrium adsorption time was 12 h, with pseudo second-order as the best fit. The thermal dynamic tests showed that the adsorption was spontaneous and, together with the evidence from the sequential extraction and desorption experiments, indicated the initial mechanism was physical attraction to the surface followed by chemical reactions which prevented re-release. These results suggested that RCA could be used for both wastewater treatment and P recovery. PMID- 29462989 TI - Memristic Characteristics from Bistable to Tristable Memory with Controllable Charge Trap Carbon Nanotubes. AB - The incorporation of the one-dimensional carbon nanomaterial carbon nanotubes (CNTs) in poly(methyl methacrylate) (PMMA) was found to successfully develop a resistive switching. It implements memristic characteristics which shift from bistable to tristable memory. The localized current pathways in the organic nanocomposite layers for each intermediate resistive state (IRS) are attributed to the trapping mechanism consistent with the fluorescent measurements. Multi-bit organic memories have attracted considerable interest, which provide an effective way to increase the memory density per unit cell area. This study will be useful for the development and tuning of multi-bit storable organic nanocomposite memory device systems. PMID- 29462988 TI - A pi-Halogen Bond of Dibenzofuranones with the Gatekeeper Phe113 in Human Protein Kinase CK2 Leads to Potent Tight Binding Inhibitors. AB - Human protein kinase CK2 is an emerging target for neoplastic diseases. Potent lead structures for human CK2 inhibitors are derived from dibenzofuranones. Two new derivatives, 7,9-dichloro-1,2-dihydro-8-hydroxy-4-[(4-methoxyphenylamino) methylene]dibenzo[b,d]furan-3(2H)-one (4a) and (E)-1,3-dichloro-6-[(4 methoxyphenylimino)-methyl]dibenzo[b,d]furan-2,7-diol (5) were tested for inhibition of CK2 and induction of apoptosis in LNCaP cells. Both turned out to be tight binding inhibitors, with IC50 values of 7 nM (4a) and 5 nM (5) and an apparent Ki value of 0.4 nM for both. Compounds 4a and 5 reduced cellular CK2 activity, indicating cell permeability. Cell viability was substantially impaired in LNCaP cells, as well as apoptosis was induced, which was not appearing in non neoplastic ARPE-19 cells. Co-crystallization of 4a and 5 revealed an unexpected pi-halogen bond of the chloro substituent at C9 with the gatekeeper amino acid Phe113, leading to an inverted binding mode in comparison to parent compound 4b, with the Cl at C6 instead, which was co-crystallized as a control. This indicates that the position of the chloro substituent on ring A of the dibenzofuran scaffold is responsible for an inversion of the binding mode that enhances potency. PMID- 29462990 TI - Exploration of Rice Husk Compost as an Alternate Organic Manure to Enhance the Productivity of Blackgram in Typic Haplustalf and Typic Rhodustalf. AB - The present study was aimed at using cellulolytic bacterium Enhydrobacter and fungi Aspergillus sp. for preparing compost from rice husk (RH). Further, the prepared compost was tested for their effect on blackgram growth promotion along with different levels of recommended dose of fertilizer (RDF) in black soil (typic Haplustalf) and red soil (typic Rhodustalf) soil. The results revealed that, inoculation with lignocellulolytic fungus (LCF) Aspergillus sp. @ 2% was considered as the most efficient method of composting within a short period. Characterization of composted rice husk (CRH) was examined through scanning electron microscope (SEM) for identifying significant structural changes. At the end of composting, N, P and K content increased with decrease in CO2 evolution, C:N and C:P ratios. In comparison to inorganic fertilization, an increase in grain yield of 16% in typic Haplustalf and 17% in typic Rhodustalf soil over 100% RDF was obtained from the integrated application of CRH@ 5 t ha-1 with 50% RDF and biofertilizers. The crude protein content was maximum with the combined application of CRH, 50% RDF and biofertilizers of 20% and 21% in typic Haplustalf and typic Rhodustalf soils, respectively. Nutrient rich CRH has proved its efficiency on crop growth and soil fertility. PMID- 29462991 TI - Functionalized Asymmetric Bola-Type Amphiphiles for Efficient Gene and Drug Delivery. AB - The studies of bolaamphiphile-based nanoparticles as delivery vectors are still rudimentary and under development. In this study, several asymmetric bolaamphiphiles containing lysine and another moiety with special functions, such as pH-sensitive or cell-targeting property, were designed and synthesized. The potentials of these bolaamphiphile-based nanoparticles as versatile vectors for both nucleic acids and chemical drugs were studied. With the presence of 1,2 dioleoyl-sn-glycero-3-phosphoethanolamine (DOPE), these amphiphiles could be prepared into bolasomes, which showed good DNA binding ability and could condense plasmid DNA into nanoparticles with appropriate size and surface potential. Lys His, which has a pH-sensitive histidine on one head, exhibited higher transfection efficiency than the symmetric counterpart and comparable efficiency to commercially available transfection reagent. Mechanism studies confirmed that the bolaplexes formed from Lys-His might induce the highest cellular uptake and the best endosomal escape ability. On the other hand, these bolaamphiphiles also exhibited good drug loading ability. The self-assembly vesicles could efficiently encapsulate the hydrophobic anti-cancer drug doxorubicin (DOX) in aqueous solution with high drug loading content and encapsulation efficiency. Confocal laser scanning microscopy (CLSM) experiment and cell viability assay exhibited a controlled release of the drug with the assistance of bolasomes. It was shown that such bolaamphiphiles have great potential as nano-vectors for both drug and gene or their co-delivery. PMID- 29462992 TI - New Bacterial Phytase through Metagenomic Prospection. AB - Alkaline phytases from uncultured microorganisms, which hydrolyze phytate to less phosphorylated myo-inositols and inorganic phosphate, have great potential as additives in agricultural industry. The development of metagenomics has stemmed from the ineluctable evidence that as-yet-uncultured microorganisms represent the vast majority of organisms in most environments on earth. In this study, a gene encoding a phytase was cloned from red rice crop residues and castor bean cake using a metagenomics strategy. The amino acid identity between this gene and its closest published counterparts is lower than 60%. The phytase was named PhyRC001 and was biochemically characterized. This recombinant protein showed activity on sodium phytate, indicating that PhyRC001 is a hydrolase enzyme. The enzymatic activity was optimal at a pH of 7.0 and at a temperature of 35 degrees C. beta propeller phytases possess great potential as feed additives because they are the only type of phytase with high activity at neutral pH. Therefore, to explore and exploit the underlying mechanism for beta-propeller phytase functions could be of great benefit to biotechnology. PMID- 29462995 TI - Research on the Additional Secondary Phase Factor for Automatic Identification System Signals Transmitted over a Rough Sea Surface. AB - This paper investigates the Additional Secondary Phase Factor (ASF) characteristics of Automatic Identification System (AIS) signals spreading over a rough sea surface. According to the change of the ASFs for AIS signals in different signal form, the influences of the different propagation conditions on the ASFs are analyzed. The expression, numerical calculation, and simulation analysis of the ASFs of AIS signal are performed in the rough sea surface. The results contribute to the high-accuracy propagation delay measurement of AIS signals spreading over the rough sea surface as, well as providing a reference for reliable communication link design in marine engineering for Very High Frequency (VHF) signals. PMID- 29462993 TI - The Biased G-Protein-Coupled Receptor Agonism Bridges the Gap between the Insulin Receptor and the Metabolic Syndrome. AB - Insulin signaling, as mediated through the insulin receptor (IR), plays a critical role in metabolism. Aberrations in this signaling cascade lead to several pathologies, the majority of which are classified under the umbrella term "metabolic syndrome". Although many of these pathologies are associated with insulin resistance, the exact mechanisms are not well understood. One area of current interest is the possibility of G-protein-coupled receptors (GPCRs) influencing or regulating IR signaling. This concept is particularly significant, because GPCRs have been shown to participate in cross-talk with the IR. More importantly, GPCR signaling has also been shown to preferentially regulate specific downstream signaling targets through GPCR agonist bias. A novel study recently demonstrated that this GPCR-biased agonism influences the activity of the IR without the presence of insulin. Although GPCR-IR cross-talk has previously been established, the notion that GPCRs can regulate the activation of the IR is particularly significant in relation to metabolic syndrome and other pathologies that develop as a result of alterations in IR signaling. As such, we aim to provide an overview of the physiological and pathophysiological roles of the IR within metabolic syndrome and its related pathologies, including cardiovascular health, gut microflora composition, gastrointestinal tract functioning, polycystic ovarian syndrome, pancreatic cancer, and neurodegenerative disorders. Furthermore, we propose that the GPCR-biased agonism may perhaps mediate some of the downstream signaling effects that further exacerbate these diseases for which the mechanisms are currently not well understood. PMID- 29462994 TI - Improving Behavioral Support for Smoking Cessation in Pregnancy: What Are the Barriers to Stopping and Which Behavior Change Techniques Can Influence These? Application of Theoretical Domains Framework. AB - Behavioral support interventions are used to help pregnant smokers stop; however, of those tested, few are proven effective. Systematic research developing effective pregnancy-specific behavior change techniques (BCTs) is ongoing. This paper reports contributory work identifying potentially-effective BCTs relative to known important barriers and facilitators (B&Fs) to smoking cessation in pregnancy; to detect priority areas for BCTs development. A Nominal Group Technique with cessation experts (n = 12) elicited an expert consensus on B&Fs most influencing women's smoking cessation and those most modifiable through behavioral support. Effective cessation interventions in randomized trials from a recent Cochrane review were coded into component BCTs using existing taxonomies. B&Fs were categorized using Theoretical Domains Framework (TDF) domains. Matrices, mapping BCT taxonomies against TDF domains, were consulted to investigate the extent to which BCTs in existing interventions target key B&Fs. Experts ranked "smoking a social norm" and "quitting not a priority" as most important barriers and "desire to protect baby" an important facilitator to quitting. From 14 trials, 23 potentially-effective BCTs were identified (e.g., information about consequences). Most B&Fs fell into "Social Influences", "Knowledge", "Emotions" and "Intentions" TDF domains; few potentially-effective BCTs mapped onto every TDF domain. B&Fs identified by experts as important to cessation, are not sufficiently targeted by BCT's currently within interventions for smoking cessation in pregnancy. PMID- 29462996 TI - Nanocantilevers with Adjustable Static Deflection and Significantly Tunable Spectrum Resonant Frequencies for Applications in Nanomechanical Mass Sensors. AB - Nanocantilevers have become key components of nanomechanical sensors that exploit changes in their resonant frequencies or static deflection in response to the environment. It is necessary that they can operate at a given, but adjustable, resonant frequency and/or static deflection ranges. Here we propose a new class of nanocantilevers with a significantly tunable spectrum of the resonant frequencies and changeable static deflection utilizing the unique properties of a phase-transforming NiTi film sputtered on the usual nanotechnology cantilever materials. The reversible frequency tuning and the adjustable static deflection are obtained by intentionally changing the Young's modulus and the interlayer stress of the NiTi film during its phase transformation, while the usual cantilever elastic materials guarantee a high frequency actuation (up to tens of MHz). By incorporating the NiTi phase transformation characteristic into the classical continuum mechanics theory we present theoretical models that account for the nanocantilever frequency shift and variation in static deflection caused by a phase transformation of NiTi film. Due to the practical importance in nanomechanical sensors, we carry out a complete theoretical analysis and evaluate the impact of NiTi film on the cantilever Young's modulus, static deflection, and the resonant frequencies. Moreover, the importance of proposed NiTi nanocantilever is illustrated on the nanomechanical based mass sensors. Our findings will be of value in the development of advanced nanotechnology sensors with intentionally-changeable physical and mechanical properties. PMID- 29462997 TI - Effect of a Fibroin Enzymatic Hydrolysate on Memory Improvement: A Placebo Controlled, Double-Blind Study. AB - The consumption of a specifically prepared silk fibroin protein enzymatic hydrolysate (FPEH) has been reported to improve cognitive function in healthy humans. The objective of the current study is to evaluate the dose-dependent effects of the FPEH on memory. Healthy adults with an average age of approximately 55 years were administered doses of 0, 280, 400 and 600 mg of FPEH per day in two divided doses for 3 weeks. The Rey-Kim Auditory Verbal Learning Test and the Rey-Kim Complex Figure Test of the Rey-Kim Memory Test were used to evaluate memory at baseline and after 3 weeks. The scores for each test were combined into the memory quotient score (MQ). Learning gradient, memory maintenance, retrieval efficacy, and drawing/recall scores were also compared. After 3 weeks of FPEH, dose-dependent increases were observed for the MQ, the learning gradient, the numbers of words remembered, the retrieval efficiency, and drawing/recall. The optimal dose for FPEH was 400 or 600 mg, depending on the end point measured. No adverse effects were reported. FPEH significantly improved measurements of memory in healthy adults by 3 weeks at doses over 280 mg daily, with an apparent plateau effect at 400-600 mg daily. PMID- 29462999 TI - An On-Site Simultaneous Semi-quantification of Aflatoxin B1, Zearalenone, and T-2 Toxin in Maize- and Cereal-based Feed via Multicolor Immunochromatographic Assay. AB - Multiple-mycotoxin contamination has been frequently found in the agro-food monitoring due to the coexistence of fungi. However, many determination methods focused on a single mycotoxin, highlighting the demand for on-site determination of multiple mycotoxins in a single run. We develop a multicolor-based immunochromatographic strip (ICS) for simultaneous determination of aflatoxin B1 (AFB1), zearalenone (ZEN) and T-2 toxin in maize- and cereal-based animal feeds. The nanoparticles with different colors are conjugated with three monoclonal antibodies, which serve as the immunoassay probes. The decrease in color intensity is observed by the naked eyes, providing simultaneous quantification of three mycotoxins. The visible limits of detection for AFB1, ZEN and T-2 are estimated to be 0.5, 2, and 30 ng/mL, respectively. The cut-off values are 1, 10, and 50 ng/mL, respectively. Considerable specificity and stability are found using real samples. The results are in excellent agreement with those from high performance liquid chromatography/tandem mass spectrometry. The multi-color ICS boasts sensitive and rapid visual differentiation and simultaneous semi quantification of aflatoxin B1, zearalenone and T-2 toxin in maize- and cereal based feed samples within 20 min. PMID- 29462998 TI - AOX1-Subfamily Gene Members in Olea europaea cv. "Galega Vulgar"-Gene Characterization and Expression of Transcripts during IBA-Induced in Vitro Adventitious Rooting. AB - Propagation of some Olea europaea L. cultivars is strongly limited due to recalcitrant behavior in adventitious root formation by semi-hardwood cuttings. One example is the cultivar "Galega vulgar". The formation of adventitious roots is considered a morphological response to stress. Alternative oxidase (AOX) is the terminal oxidase of the alternative pathway of the plant mitochondrial electron transport chain. This enzyme is well known to be induced in response to several biotic and abiotic stress situations. This work aimed to characterize the alternative oxidase 1 (AOX1)-subfamily in olive and to analyze the expression of transcripts during the indole-3-butyric acid (IBA)-induced in vitro adventitious rooting (AR) process. OeAOX1a (acc. no. MF410318) and OeAOX1d (acc. no. MF410319) were identified, as well as different transcript variants for both genes which resulted from alternative polyadenylation events. A correlation between transcript accumulation of both OeAOX1a and OeAOX1d transcripts and the three distinct phases (induction, initiation, and expression) of the AR process in olive was observed. Olive AOX1 genes seem to be associated with the induction and development of adventitious roots in IBA-treated explants. A better understanding of the molecular mechanisms underlying the stimulus needed for the induction of adventitious roots may help to develop more targeted and effective rooting induction protocols in order to improve the rooting ability of difficult-to-root cultivars. PMID- 29463000 TI - AWRK6, A Synthetic Cationic Peptide Derived from Antimicrobial Peptide Dybowskin 2CDYa, Inhibits Lipopolysaccharide-Induced Inflammatory Response. AB - Lipopolysaccharides (LPS) are major outer membrane components of Gram-negative bacteria and produce strong inflammatory responses in animals. Most antibiotics have shown little clinical anti-endotoxin activity while some antimicrobial peptides have proved to be effective in blocking LPS. Here, the anti-LPS activity of the synthetic peptide AWRK6, which is derived from antimicrobial peptide dybowskin-2CDYa, has been investigated in vitro and in vivo. The positively charged alpha-helical AWRK6 was found to be effective in blocking the binding of LBP (LPS binding protein) with LPS in vitro using ELISA. In a murine endotoxemia model, AWRK6 offered satisfactory protection efficiency against endotoxemia death, and the serum levels of LPS, IL-1beta, IL-6, and TNF-alpha were found to be attenuated using ELISA. Further, histopathological analysis suggested that AWRK6 could improve the healing of liver and lung injury in endotoxemia mice. The results of real-time PCR and Western blotting showed that AWRK6 significantly reversed LPS-induced TLR4 overexpression and IkappaB depression, as well as the enhanced IkappaB phosphorylation. Additionally, AWRK6 did not produce any significant toxicity in vivo and in vitro. In summary, AWRK6 showed efficacious protection from LPS challenges in vivo and in vitro, by blocking LPS binding to LBP, without obvious toxicity, providing a promising strategy against LPS-induced inflammatory responses. PMID- 29463001 TI - The Cyanthin Diterpenoid and Sesterterpene Constituents of Hericium erinaceus Mycelium Ameliorate Alzheimer's Disease-Related Pathologies in APP/PS1 Transgenic Mice. AB - Hericium erinaceus was used in traditional Chinese medicine for physiologically beneficial medicines. Recently, it has become a candidate in causing positive brain health-related activities. We previously reported that Hericium erinaceus mycelium ameliorates Alzheimer's disease (AD)-related pathologies. To reveal the role of the cyanthin diterpenoid and sesterterpene constituents on this effects, erinacine A and S were isolated and their effects on attenuating AD-related pathology in APPswe/PS1dE9 transgenic mice were investigated. A 30 day short-term administration of erinacine A and S were performed to explore the effect of each erinacine on AD-related pathology including amyloid beta production and degradation, plaque formation, plaque growth, glial activation and neurogenesis deterioration. Our results indicated the benefit effects of both erinacine A and S in cerebrum of APPswe/PS1dE9 mice, including: (1) attenuating cerebral plaque loading by inhibiting plaque growth; (2) diminishing the activation of glial cells; (3) raising the level of insulin degrading enzyme; and (4) promoting hippocampal neurogenesis. Moreover, erinacine A reduced the level of insoluble amyloid beta and C-terminal fragment of amyloid precursor protein which was not mediated by erinacine S. We further performed a long term administration of erinacine A and found that erinacine A recovered the impairment in the tasks including burrowing, nesting, and Morris water maze. Our data pointed out that although both erinacine A and S reduce AD pathology via reducing amyloid deposition and promoting neurogenesis, erinacine A can also inhibit amyloid beta production and is worth to be further developed for AD therapeutic use. PMID- 29463002 TI - Inhibitory Effect of Purpurogallin on Osteoclast Differentiation in Vitro through the Downregulation of c-Fos and NFATc1. AB - Purpurogallin, a benzotropolone-containing natural compound, has been reported to exhibit numerous biological and pharmacological functions, such as antioxidant, anticancer, and anti-inflammatory effects. In this study, we enzymatically synthesized purpurogallin from pyrogallol and investigated its role in receptor activator of nuclear factor-kappaB ligand (RANKL)-induced osteoclastogenesis. Purpurogallin attenuated the formation of multinucleated tartrate-resistant acid phosphatase (TRAP)-positive osteoclasts from bone marrow macrophages (BMMs) without causing cytotoxicity, and suppressed upregulation of osteoclast-specific markers, including TRAP (Acp5), cathepsin K (Ctsk), and dendritic cell-specific transmembrane protein (Dcstamp). However, purpurogallin did not affect the bone resorbing function of mature osteoclasts evident by the resorption pit assay. Activation of mitogen-activated protein kinases, Akt and IkB pathways in RANK signaling were not altered by purpurogallin, whereas the expression of c-Fos and NFATc1, key transcriptional regulators in osteoclastogenesis, was dramatically inhibited by purpurogallin. Purpurogallin also significantly reduced the expression level of B lymphocyte-induced maturation protein-1 (Blimp1) gene (Prdm1). Further, downregulation of Blimp1 led to forced expression of anti osteoclastogenic genes, including interferon regulatory factor-8 (Irf8) and B cell lymphoma 6 (Bcl6) genes. Taken together, our data suggested that purpurogallin inhibits osteoclast differentiation via downregulation of c-Fos and NFATc1. PMID- 29463004 TI - Advanced EUS Guided Tissue Acquisition Methods for Pancreatic Cancer. AB - Pancreas cancer is a lethal cancer as the majority patients are diagnosed at an advanced incurable stage. Despite improvements in diagnostic modalities and management strategies, including surgery and chemotherapies, the outcome of pancreas cancer remains poor. Endoscopic ultrasound (EUS) is an important imaging tool for pancreas cancer. For decades, resected pancreas cancer and other cancer specimens have been used to identify tissue biomarkers or genomics for precision therapy; however, only 20% of patients undergo surgery, and thus, this framework is not useful for unresectable pancreas cancer. With advancements in needle technologies, tumor specimens can be obtained at the time of tissue diagnosis. Tumor tissue can be used for development of personalized cancer treatment, such as performing whole exome sequencing and global genomic profiling of pancreas cancer, development of tissue biomarkers, and targeted mutational assays for precise chemotherapy treatment. In this review, we discuss the recent advances in tissue acquisition of pancreas cancer. PMID- 29463003 TI - The miRNA Mirage: How Close Are We to Finding a Non-Invasive Diagnostic Biomarker in Endometriosis? A Systematic Review. AB - BACKGROUND: Endometriosis is a common disorder of the reproductive age group, characterised by the presence of ectopic endometrial tissue. The disease not only causes enormous suffering to the affected women, but also brings a tremendous medical and economic burden to bear on society. There is a long lag phase between the onset and diagnosis of the disease, mainly due to its non-specific symptoms and the lack of a non-invasive test. Endometriosis can only be diagnosed invasively by laparoscopy. A specific, non-invasive test to diagnose endometriosis is an unmet clinical need. The recent discovery of microRNAs (miRNAs) as modulators of gene expression, and their stability and specificity, make them an attractive candidate biomarker. Various studies on miRNAs in endometriosis have identified their cardinal role in the pathogenesis of the disease, and have proposed them as potential biomarkers in endometriosis. Rationale/Objectives: The aims of this review were to study the role of circulatory miRNAs in endometriosis, and bring to light whether circulatory miRNAs could be potential non-invasive biomarkers to diagnose the disease. SEARCH METHODS: Three databases, PubMed, EMBASE, and BIOSIS were searched, using a combination of Mesh or Emtree headings and free-text terms, to identify literature relating to circulating miRNAs in endometriosis published from 1996 to 31 December 2017. Only peer-reviewed, full-text original research articles in English were included in the current review. The studies meeting the inclusion criteria were critically assessed and checked using the QUADAS-2 (Quality Assessment of Diagnostic Accuracy Studies) tool. The dysregulated miRNAs were assessed regarding the concordance between the various studies and their role in the disease. OUTCOMES: Nine studies were critically analysed, and 42 different miRNAs were found to be dysregulated in them, with only one common miRNA (miR 20a) differentially expressed in more than one study. miR-17-5p/20a, miR-200, miR 199a, miR-143, and miR-145 were explored for their pivotal role in the aetiopathogenesis of endometriosis. Wider implications: It is emerging that miRNAs play a central role in the pathogenesis of endometriosis and have the potential of being promising biomarkers. Circulating miRNAs as a non-invasive diagnostic tool may shorten the delay in the diagnosis of the disease, thus alleviating the suffering of women and reducing the burden on health care systems. However, despite numerous studies on circulating miRNAs in endometriosis, no single miRNA or any panel of them seems to meet the criteria of a diagnostic biomarker. The disagreement between the various studies upholds the demand of larger, well-controlled systematic validation studies with uniformity in the research approaches and involving diverse populations. PMID- 29463006 TI - Long-Term Oncologic Outcomes, Opioid Use, and Complications after Esophageal Cancer Surgery. AB - Effective and adequate opioid use and prevention of postoperative complications are important for enhanced recovery after surgery. We examined the effects of postoperative opioid use and postoperative complications on overall survival and recurrence-free survival after esophageal cancer surgery. This retrospective cohort study analyzed the records of patients diagnosed with esophageal cancer who underwent the Ivor Lewis operation between January 2005 and December 2011. We collected data on total opioid use for 8 days postoperatively, as well as information on postoperative complications (Clavien-Dindo classification). One hundred and twenty-one patients were included in the final analysis. Total opioid use was not significantly associated with overall survival (p = 0.520) and recurrence-free survival (p = 0.818). In contrast, the hazard ratio of postoperative overall survival was significantly higher with respect to Clavien Dindo classification 1-2 (hazard ratio: 2.009, p = 0.046), 3a-3b (hazard ratio: 5.759, p < 0.001), and 4a-5 (hazard ratio: 3.982, p = 0.020) complications compared to no complications. Additionally, the hazard ratio of the recurrence free survival was significantly higher in class 1-2 complications (hazard ratio: 2.336, p = 0.028) compared to none. Our study demonstrates that postoperative opioid use is not associated with survival and recurrence-free survival after esophageal cancer surgery, while postoperative complications may increase the hazard ratio for survival and recurrence-free survival. PMID- 29463005 TI - Mechanisms of Pulmonary Escape and Dissemination by Cryptococcus neoformans. AB - Cryptococcus neoformans is a common environmental saprophyte and human fungal pathogen that primarily causes disease in immunocompromised individuals. Similar to many environmentally acquired human fungal pathogens, C. neoformans initiates infection in the lungs. However, the main driver of mortality is invasive cryptococcosis leading to fungal meningitis. After C. neoformans gains a foothold in the lungs, a critical early step in invasion is transversal of the respiratory epithelium. In this review, we summarize current knowledge relating to pulmonary escape. We focus on fungal factors that allow C. neoformans to disseminate from the lungs via intracellular and extracellular routes. PMID- 29463007 TI - New Insights into the Role of Neuron-Specific Enolase in Neuro-Inflammation, Neurodegeneration, and Neuroprotection. AB - Neurodegeneration is a complex process that leads to irreversible neuronal damage and death in spinal cord injury (SCI) and various neurodegenerative diseases, which are serious, debilitating conditions. Despite exhaustive research, the cause of neuronal damage in these degenerative disorders is not completely understood. Elevation of cell surface alpha-enolase activates various inflammatory pathways, including the production of pro-inflammatory cytokines, chemokines, and some growth factors that are detrimental to neuronal cells. While alpha-enolase is present in all neurological tissues, it can also be converted to neuron specific enolase (NSE). NSE is a glycolytic enzyme found in neuronal and neuroendocrine tissues that may play a dual role in promoting both neuroinflammation and neuroprotection in SCI and other neurodegenerative events. Elevated NSE can promote ECM degradation, inflammatory glial cell proliferation, and actin remodeling, thereby affecting migration of activated macrophages and microglia to the injury site and promoting neuronal cell death. Thus, NSE could be a reliable, quantitative, and specific marker of neuronal injury. Depending on the injury, disease, and microenvironment, NSE may also show neurotrophic function as it controls neuronal survival, differentiation, and neurite regeneration via activation of phosphatidylinositol-4,5-bisphosphate 3-kinase (PI3K) and mitogen-activated protein kinase (MAPK) signaling pathways. This review discusses possible implications of NSE expression and activity in neuroinflammation, neurodegeneration, and neuroprotection in SCI and various neurodegenerative diseases for prognostic and therapeutic potential.

AB - The interfacial electronic structures of a bilayer of fullerene (C60) and zinc phthalocyanine (ZnPc) grown on vanadium pentoxide (V2O5) thin films deposited using radio frequency sputtering under various conditions were studied using X ray and ultraviolet photoelectron spectroscopy. The energy difference between the highest occupied molecular orbital (HOMO) level of the ZnPc layer and the lowest unoccupied molecular orbital (LUMO) level of the C60 layer was determined and compared with that grown on an indium tin oxide (ITO) substrate. The energy difference of a heterojunction on all V2O5 was found to be 1.3~1.4 eV, while that on ITO was 1.1 eV. This difference could be due to the higher binding energy of the HOMO of ZnPc on V2O5 than that on ITO regardless of work functions of the substrates. We also determined the complete energy level diagrams of C60/ZnPc on V2O5 and ITO. PMID- 29463010 TI - Differences in Sirtuin Regulation in Response to Calorie Restriction in Cryptococcus neoformans. AB - Cryptococcus neoformans successfully replicates in low glucose in infected patients. In the serotype A strain, H99, growth in this condition prolongs lifespan regulated by SIR2, and can be modulated with SIR2-specific drugs. Previous studies show that lifespan modulation of a cryptococcal population affects its sensitivity to antifungals, and survival in an infection model. Sirtuins and their role in longevity are conserved among fungi; however, the effect of glucose starvation is not confirmed even in Saccharomyces cerevisiae. Lifespan analysis of C. neoformans strains in low glucose showed that 37.5% exhibited pro-longevity, and lifespan of a serotype D strain, RC2, was shortened. Transcriptome comparison of H99 and RC2 under calorie restriction demonstrated differences, confirmed by real-time PCR showing that SIR2, TOR1, SCH9, and PKA1 expression correlated with lifespan response to calorie restriction. As expected, RC2-sir2Delta cells exhibited a shortened lifespan, which was reconstituted. However, shortened lifespan from calorie restriction was independent of SIR2. In contrast to H99 but consistent with altered SIR2 regulation, SIR2-specific drugs did not affect outcome of RC2 infection. These data suggest that SIR2 regulation and response to calorie restriction varies in C. neoformans, which should be considered when Sirtuins are investigated as potential therapy targets for fungal infections.

AB - Abstract: Memory extinction is referred to as a learning process in which a conditioned response (CR) progressively reduces over time as an animal learns to uncouple a response from a stimulus. Extinction occurs when the rat is placed into a context without shock after training. Docosahexaenoic acid (DHA, C22:6, n 3) is implicated in memory formation in mammalian brains. In a two-way active shuttle-avoidance apparatus, we examined whether DHA affects the extinction memory and the expression of brain cognition-related proteins, including gastrin releasing peptide receptor (GRPR), brain-derived neurotrophic factor receptor (BDNFR) tyrosine kinase receptor B (TrKB), and N-methyl-d-aspartate receptor (NMDAR) subunits NR2A and NR2B. Also, the protein levels of GRP, BDNF, postsynaptic density protein-95 (PSD-95), and vesicular acetylcholine transporter (VAChT), and the antioxidative potentials, in terms of lipid peroxide (LPO) and reactive oxygen species (ROS), were examined in the hippocampus. During the acquisition phase, the rats received a conditioned stimulus (CS-tone) paired with an unconditioned stimulus (UCS foot shock) for three consecutive days (Sessions S1, S2, and S3, each consisting of 30-trials) after 12 weeks of oral administration of DHA. After a three-day interval, the rats were re-subjected to two extinction sessions (S4, S5), each comprising 30 trials of CS alone. During the acquisition training in S1, the shock-related avoidance frequency (acquisition memory) was significantly higher in the DHA-administered rats compared with the control rats. The avoidance frequency, however, decreased with successive acquisition trainings in sessions S2 and S3. When the rats were subjected to the extinction sessions after a break for consolidation, the conditioned response (CR) was also significantly higher in the DHA-administered rats. Interestingly, the freezing responses (frequency and time) also significantly decreased in the DHA-administered rats, thus suggesting that a higher coping capacity was present during fear stress in the DHA-administered rats. DHA treatments increased the mRNA levels of GRPR, BDNF receptor TrKB, and NMDAR subunit NR2B. DHA also increased the protein levels of GRP, BDNF, PSD-95, and VAChT, and the antioxidative potentials in the hippocampus. These results suggest the usefulness of DHA for treating stress disorders.

AB - Phytochemical isolation of fermented Alnus sibirica (FAS) which was produced by using Lactobacillus plantarum subsp. argentoratensis, exhibited multiple and different composition compared with the original plant. Anti-allergic contact dermatitis (anti-ACD)/anti-atopic dermatitis (anti-AD) activities (visual observation and regulation of Th1/Th2 cytokines and IgE in blood) of FAS and the barks of Alnus sibirica extract (AS) and the two diarylheptanoids, hirsutenone (1) and muricarpon B (2), which are major components of FAS, were measured in vitro and in vivo. FAS, AS and the two compounds showed potent anti-oxidative, anti-inflammatory, anti-ACD and anti-AD activity. In particular, FAS showed more potent biological activity than AS. Thus, fermentation might be a prominent way to enhance the biological activity compared with the original plant. In addition, compounds (1) and (2) might be developed as functional materials or herbal medicines for ACD and AD.

AB - In this study, polydimethylsiloxane (PDMS) and conductive carbon nanoparticles were combined to fabricate a conductive elastomer PDMS (CPDMS). A high sensitive and flexible CPDMS strain sensor is fabricated by using stamping-process based micro patterning. Compared with conventional sensors, flexible strain sensors are more suitable for medical applications but are usually fabricated by photolithography, which suffers from a large number of steps and difficult mass production. Hence, we fabricated flexible strain sensors using a stamping-process with fewer processes than photolithography. The piezoresistive coefficient and sensitivity of the flexible strain sensor were improved by sensor pattern design and thickness change. Micro-patterning is used to fabricate various CPDMS microstructure patterns. The effect of gauge pattern was evaluated with ANSYS simulations. The piezoresistance of the strain gauges was measured and the gauge factor determined. Experimental results show that the piezoresistive coefficient of CPDMS is approximately linear. Gauge factor measurement results show that the gauge factor of a 140.0 MUm thick strain gauge with five grids is the highest.

AB - Precise structure-property relation of a biodegradable polymer (e.g., aliphatic polyester) is anticipated only if monomer units and chiral centers are arranged in a defined primary sequence as a biomacromolecule. An emerging synthetic methodology, namely segmer assembly polymerization (SAP), is introduced in this paper to reveal the latest progress in polyester synthesis. Almost any periodic polyester envisioned can be synthesized via SAP using a programed linear or cyclic monomer. In this context, the macroscopic properties of a biodegradable polymer are fundamentally determined by microstructural information through a bottom-up approach. It can be highlighted that SAP ideally combines the precision of organic synthesis and the high efficiency of a polymerization reaction. Previously reported strategies including nucleophilic displacement, polyesterification, cross-metathesis polymerization (CMP), ring-opening polymerization (ROP), ring-opening metathesis polymerization (ROMP) and entropy driven ring-opening metathesis polymerization (ED-ROMP) are critically reviewed in this paper to shed light on precision synthesis of aliphatic polyesters via SAP. Emerging yet challenging, SAP is a paradigm which reflects the convergence of organic and polymer chemistries and is also an efficient pathway to microstructural control. The current status, future challenges and promising trends in this realm are analyzed and discussed in this overview of the state-of the-art. PMID- 29463014 TI - Exploring the History of Chloroplast Capture in Arabis Using Whole Chloroplast Genome Sequencing. AB - Chloroplast capture occurs when the chloroplast of one plant species is introgressed into another plant species. The phylogenies of nuclear and chloroplast markers from East Asian Arabis species are incongruent, which indicates hybrid origin and shows chloroplast capture. In the present study, the complete chloroplast genomes of A. hirsuta, A. nipponica, and A. flagellosa were sequenced in order to analyze their divergence and their relationships. The chloroplast genomes of A. nipponica and A. flagellosa were similar, which indicates chloroplast replacement. If hybridization causing chloroplast capture occurred once, divergence between recipient species would be lower than between donor species. However, the chloroplast genomes of species with possible hybrid origins, A. nipponica and A. stelleri, differ at similar levels to possible maternal donor species A. flagellosa, which suggests that multiple hybridization events have occurred in their respective histories. The mitochondrial genomes exhibited similar patterns, while A. nipponica and A. flagellosa were more similar to each other than to A. hirsuta. This suggests that the two organellar genomes were co-transferred during the hybridization history of the East Asian Arabis species. PMID- 29463016 TI - Synthesis, Structural Property, Photophysical Property, Photocatalytic Property of Novel ZnBiErO4 under Visible Light Irradiation. AB - A novel photocatalyst ZnBiErO4 was firstly synthesized by solid-state reaction method and its structural and photocatalytic properties were analyzed by scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy and UV Vis diffuse reflectance. The results demonstrated that ZnBiErO4 crystallized with tetragonal crystal structure with space group I41/A. The lattice parameters for ZnBiErO4 were proved to be a = b = 10.255738 A and c = 9.938888 A. The band gap of ZnBiErO4 was estimated to be about 1.69 eV. Compared with nitrogen doped TiO2, ZnBiErO4 showed excellent photocatalytic activities for degrading methyl blue during visible light irradiation. The photocatalytic degradation of methyl blue with ZnBiErO4 or N-doped TiO2 as catalyst followed the first-order reaction kinetics. Moreover, the apparent first-order rate constant of ZnBiErO4 or N-doped TiO2 was 0.01607 min-1 or 0.00435 min-1. The reduction of total organic carbon, formation of inorganic products, such as SO42- and NO3- and the evolution of CO2 revealed the continuous mineralization of methyl blue during the photocatalytic process. ZnBiErO4 photocatalyst had great potential to purify textile industry wastewater. PMID- 29463015 TI - Association between Bone Mineral Density of Femoral Neck and Geriatric Nutritional Risk Index in Rheumatoid Arthritis Patients Treated with Biological Disease-Modifying Anti-Rheumatic Drugs. AB - Treatment of rheumatoid arthritis (RA) with biological disease-modifying anti rheumatic drugs (bDMARDs) induces rapid remission. However, osteoporosis and its management remains a problem. The Geriatric Nutritional Risk Index (GNRI) evaluates the risk of malnutrition-related complications in elderly patients and has been shown to be a significant predictor of many diseases. We evaluated the correlation between GNRI and RA activity. In addition, risk factors for femoral neck bone loss were evaluated in RA patients treated with bDMARDs. We retrospectively examined the medical records of 146 patients with RA, collecting and recording the patients' demographic and clinical characteristics. Bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry. Inverse correlations were observed between GNRI and disease duration, disease activity score-28 joint count serum C-reactive protein (CRP), simple disease activity index, modified health assessment questionnaire score and CRP. GNRI showed correlation with femoral neck BMD and femoral neck BMD <= 70% of young adult men (YAM). Multiple regression analysis showed that female sex, increased age and lower GNRI were risk factors for lower BMD of the femoral neck. Multivariate binomial logistic regression analysis showed that female sex (odd ratio: 3.67) and lower GNRI (odd ratio: 0.87) were risk factors for BMD <= 70% of YAM. Because the GNRI is a simple method, it might be a simple predictor for RA activity and BMD status in RA patients. Complementary nutritional therapies might improve RA activity and osteoporosis in RA patients who have undergone treatment with bDMARDs. PMID- 29463017 TI - Identification of Novel Protein Kinase Receptor Type 2 Inhibitors Using Pharmacophore and Structure-Based Virtual Screening. AB - The Protein Kinase Receptor type 2 (RIPK2) plays an important role in the pathogenesis of inflammatory diseases; it signals downstream of the NOD1 and NOD2 intracellular sensors and promotes a productive inflammatory response. However, excessive NOD2 signaling has been associated with various diseases, including sarcoidosis and inflammatory arthritis; the pharmacological inhibition of RIPK2 is an affinity strategy that demonstrates an increased expression of pro inflammatory secretion activity. In this study, a pharmacophoric model based on the crystallographic pose of ponatinib, a potent RIPK2 inhibitor, and 30 other ones selected from the BindingDB repository database, was built. Compounds were selected based on the available ZINC compounds database and in silico predictions of their pharmacokinetic, toxicity and potential biological activity. Molecular docking was performed to identify the probable interactions of the compounds as well as their binding affinity with RIPK2. The compounds were analyzed to ponatinib and WEHI-345, which also used as a control. At least one of the compounds exhibited suitable pharmacokinetic properties, low toxicity and an interesting binding affinity and high fitness compared with the crystallographic pose of WEHI-345 in complex with RIPK2. This compound also possessed suitable synthetic accessibility, rendering it a potential and very promising RIPK2 inhibitor to be further investigated in regards to different diseases, particularly inflammatory ones. PMID- 29463018 TI - Towards a Clinical Decision Support System for External Beam Radiation Oncology Prostate Cancer Patients: Proton vs. Photon Radiotherapy? A Radiobiological Study of Robustness and Stability. AB - We present a methodology which can be utilized to select proton or photon radiotherapy in prostate cancer patients. Four state-of-the-art competing treatment modalities were compared (by way of an in silico trial) for a cohort of 25 prostate cancer patients, with and without correction strategies for prostate displacements. Metrics measured from clinical image guidance systems were used. Three correction strategies were investigated; no-correction, extended-no-action limit, and online-correction. Clinical efficacy was estimated via radiobiological models incorporating robustness (how probable a given treatment plan was delivered) and stability (the consistency between the probable best and worst delivered treatments at the 95% confidence limit). The results obtained at the cohort level enabled the determination of a threshold for likely clinical benefit at the individual level. Depending on the imaging system and correction strategy; 24%, 32% and 44% of patients were identified as suitable candidates for proton therapy. For the constraints of this study: Intensity-modulated proton therapy with online-correction was on average the most effective modality. Irrespective of the imaging system, each treatment modality is similar in terms of robustness, with and without the correction strategies. Conversely, there is substantial variation in stability between the treatment modalities, which is greatly reduced by correction strategies. This study provides a 'proof-of-concept' methodology to enable the prospective identification of individual patients that will most likely (above a certain threshold) benefit from proton therapy. PMID- 29463019 TI - Health Differences between Roma and Non-Roma in the Slovak Dialyzed Population. AB - BACKGROUND: Roma health has not been studied systematically. Thus far, it has been shown that Roma compared to non-Roma have a significantly higher likelihood of getting end-stage renal disease and that their chances for survival on dialysis are lower. Evidence is lacking regarding morbidity between Roma and non Roma. The aim was to compare the health status of dialyzed Roma and non-Roma using the Charlson comorbidity index (CCI). All Slovak dialysis centers for adults were asked to fill in a questionaire with demographic and clinical data, including comorbidity. Cross-sectional analysis of 2082 patients with an average age of 63.8 +/- 13.8 years was performed. Comorbidity was expressed as the CCI, and ethnic differences were calculated. Linear regression was performed to adjust for differences in gender and age in both ethnic groups. Roma represented 13.0% of the whole dialyzed population (n = 270). Comorbidity expressed as CCI was significantly lower in the Roma population (p < 0.001). After adjusting for gender and age, ethnicity failed to be associated with the CCI in the linear regression analysis (p = 0.965, variance of the model-adjusted R2 38.6%). The health status of dialyzed Slovak Roma does not differ cross-sectionally when adjusted for age and gender from the health status of dialyzed non-Roma. PMID- 29463020 TI - Comparative Transcriptome Analysis Identifies Putative Genes Involved in Dioscin Biosynthesis in Dioscorea zingiberensis. AB - Dioscorea zingiberensis is a perennial herb native to China. The rhizome of D. zingiberensis has long been used as a traditional Chinese medicine to treat rheumatic arthritis. Dioscin is the major bioactive ingredient conferring the medicinal property described in Chinese pharmacopoeia. Several previous studies have suggested cholesterol as the intermediate to the biosynthesis of dioscin, however, the biosynthetic steps to dioscin after cholesterol remain unknown. In this study, a comprehensive D. zingiberensis transcriptome derived from its leaf and rhizome was constructed. Based on the annotation using various public databases, all possible enzymes in the biosynthetic steps to cholesterol were identified. In the late steps beyond cholesterol, cholesterol undergoes site specific oxidation by cytochrome P450s (CYPs) and glycosylation by UDP glycosyltransferases (UGTs) to yield dioscin. From the D. zingiberensis transcriptome, a total of 485 unigenes were annotated as CYPs and 195 unigenes with a sequence length above 1000 bp were annotated as UGTs. Transcriptomic comparison revealed 165 CYP annotated unigenes correlating to dioscin biosynthesis in the plant. Further phylogenetic analysis suggested that among those CYP candidates four of them would be the most likely candidates involved in the biosynthetic steps from cholesterol to dioscin. Additionally, from the UGT annotated unigenes, six of them were annotated as 3-O-UGTs and two of them were annotated as rhamnosyltransferases, which consisted of potential UGT candidates involved in dioscin biosynthesis. To further explore the function of the UGT candidates, two 3-O-UGT candidates, named Dz3GT1 and Dz3GT2, were cloned and functionally characterized. Both Dz3GT1 and Dz3GT2 were able to catalyze a C3 glucosylation activity on diosgenin. In conclusion, this study will facilitate our understanding of dioscin biosynthesis pathway and provides a basis for further mining the genes involved in dioscin biosynthesis. PMID- 29463022 TI - HPT: A High Spatial Resolution Multispectral Sensor for Microsatellite Remote Sensing. AB - Although nano/microsatellites have great potential as remote sensing platforms, the spatial and spectral resolutions of an optical payload instrument are limited. In this study, a high spatial resolution multispectral sensor, the High Precision Telescope (HPT), was developed for the RISING-2 microsatellite. The HPT has four image sensors: three in the visible region of the spectrum used for the composition of true color images, and a fourth in the near-infrared region, which employs liquid crystal tunable filter (LCTF) technology for wavelength scanning. Band-to-band image registration methods have also been developed for the HPT and implemented in the image processing procedure. The processed images were compared with other satellite images, and proven to be useful in various remote sensing applications. Thus, LCTF technology can be considered an innovative tool that is suitable for future multi/hyperspectral remote sensing by nano/microsatellites. PMID- 29463021 TI - Dynamics of Bacterial and Fungal Communities during the Outbreak and Decline of an Algal Bloom in a Drinking Water Reservoir. AB - The microbial communities associated with algal blooms play a pivotal role in organic carbon, nitrogen and phosphorus cycling in freshwater ecosystems. However, there have been few studies focused on unveiling the dynamics of bacterial and fungal communities during the outbreak and decline of algal blooms in drinking water reservoirs. To address this issue, the compositions of bacterial and fungal communities were assessed in the Zhoucun drinking water reservoir using 16S rRNA and internal transcribed spacer (ITS) gene Illumina MiSeq sequencing techniques. The results showed the algal bloom was dominated by Synechococcus, Microcystis, and Prochlorothrix. The bloom was characterized by a steady decrease of total phosphorus (TP) from the outbreak to the decline period (p < 0.05) while Fe concentration increased sharply during the decline period (p < 0.05). The highest algal biomass and cell concentrations observed during the bloom were 51.7 mg/L and 1.9*108 cell/L, respectively. The cell concentration was positively correlated with CODMn (r = 0.89, p = 0.02). Illumina Miseq sequencing showed that algal bloom altered the water bacterial and fungal community structure. During the bloom, the dominant bacterial genus were Acinetobacter sp., Limnobacter sp., Synechococcus sp., and Roseomonas sp. The relative size of the fungal community also changed with algal bloom and its composition mainly contained Ascomycota, Basidiomycota and Chytridiomycota. Heat map profiling indicated that algal bloom had a more consistent effect upon fungal communities at genus level. Redundancy analysis (RDA) also demonstrated that the structure of water bacterial communities was significantly correlated to conductivity and ammonia nitrogen. Meanwhile, water temperature, Fe and ammonia nitrogen drive the dynamics of water fungal communities. The results from this work suggested that water bacterial and fungal communities changed significantly during the outbreak and decline of algal bloom in Zhoucun drinking water reservoir. Our study highlights the potential role of microbial diversity as a driving force for the algal bloom and biogeochemical cycling of reservoir ecology. PMID- 29463023 TI - Characterization of the Body-to-Body Propagation Channel for Subjects during Sports Activities. AB - Body-to-body wireless networks (BBWNs) have great potential to find applications in team sports activities among others. However, successful design of such systems requires great understanding of the communication channel as the movement of the body components causes time-varying shadowing and fading effects. In this study, we present results of the measurement campaign of BBWN during running and cycling activities. Among others, the results indicated the presence of good and bad states with each state following a specific distribution for the considered propagation scenarios. This motivated the development of two-state semi-Markov model, for simulation of the communication channels. The simulation model was validated using the available measurement data in terms of first and second order statistics and have shown good agreement. The first order statistics obtained from the simulation model as well as the measured results were then used to analyze the performance of the BBWNs channels under running and cycling activities in terms of capacity and outage probability. Cycling channels showed better performance than running, having higher channel capacity and lower outage probability, regardless of the speed of the subjects involved in the measurement campaign. PMID- 29463024 TI - Overexpression of the Vitronectin V10 Subunit in Patients with Nonalcoholic Steatohepatitis: Implications for Noninvasive Diagnosis of NASH. AB - Nonalcoholic steatohepatitis (NASH) is the critical stage of nonalcoholic fatty liver disease (NAFLD). The persistence of necroinflammatory lesions and fibrogenesis in NASH is the leading cause of liver cirrhosis and, ultimately, hepatocellular carcinoma. To date, the histological examination of liver biopsies, albeit invasive, remains the means to distinguish NASH from simple steatosis (NAFL). Therefore, a noninvasive diagnosis by serum biomarkers is eagerly needed. Here, by a proteomic approach, we analysed the soluble low molecular-weight protein fragments flushed out from the liver tissue of NAFL and NASH patients. On the basis of the assumption that steatohepatitis leads to the remodelling of the liver extracellular matrix (ECM), NASH-specific fragments were in silico analysed for their involvement in the ECM molecular composition. The 10 kDa C-terminal fragment of the ECM protein vitronectin (VTN) was then selected as a promising circulating biomarker in discriminating NASH. The analysis of sera of patients provided these major findings: the circulating VTN fragment (i) is overexpressed in NASH patients and positively correlates with the NASH activity score (NAS); (ii) originates from the disulfide bond reduction between the V10 and the V65 subunits. In conclusion, V10 determination in the serum could represent a reliable tool for the noninvasive discrimination of NASH from simple steatosis. PMID- 29463025 TI - Inhibitory Influence of Panax notoginseng Saponins on Aspirin Hydrolysis in Human Intestinal Caco-2 Cells. AB - Herb-drug interactions are important safety concerns in clinical practice. The interactions occur firstly in the intestinal absorption for orally administered drugs. Aspirin and Panax notoginseng saponins (PNS)-based drugs are often combined in China to prevent larger-artery atherosclerosis. Here, we aimed to characterize the aspirin transport across Caco-2 cell monolayers, a model of the intestinal absorption, and further to evaluate the influence of PNS on aspirin hydrolysis and the relating mechanisms. Transcellular transport of aspirin and the influence of PNS were explored using Caco-2 cell monolayers. The protein expression of human carboxylesterase 1 (hCE1) and hCE2 in Caco-2 cells after PNS treatment was analyzed by ELISA, and the mRNA level were determined by qRT-PCR. In the study, Caco-2 cells showed high level of hydrolase activity, and most aspirin was hydrolyzed inside the cells during the transport process. Interestingly, PNS were demonstrated to inhibit the esterase activities responsible for aspirin hydrolysis in Caco-2 cells. PNS could also decrease the protein expression of hCE1 and hCE2, whereas exhibited minor effect on the mRNA expression. These results indicated that oral administration of PNS-based drugs might inhibit the hydrolysis of aspirin during intestinal absorption thus promoting its bioavailability. PMID- 29463026 TI - The Nile Rat (Arvicanthis niloticus) as a Superior Carbohydrate-Sensitive Model for Type 2 Diabetes Mellitus (T2DM). AB - Type II diabetes mellitus (T2DM) is a multifactorial disease involving complex genetic and environmental interactions. No single animal model has so far mirrored all the characteristics or complications of diabetes in humans. Since this disease represents a chronic nutritional insult based on a diet bearing a high glycemic load, the ideal model should recapitulate the underlying dietary issues. Most rodent models have three shortcomings: (1) they are genetically or chemically modified to produce diabetes; (2) unlike humans, most require high-fat feeding; (3) and they take too long to develop diabetes. By contrast, Nile rats develop diabetes rapidly (8-10 weeks) with high-carbohydrate (hiCHO) diets, similar to humans, and are protected by high fat (with low glycemic load) intake. This review describes diabetes progression in the Nile rat, including various aspects of breeding, feeding, and handling for best experimental outcomes. The diabetes is characterized by a striking genetic permissiveness influencing hyperphagia and hyperinsulinemia; random blood glucose is the best index of disease progression; and kidney failure with chronic morbidity and death are outcomes, all of which mimic uncontrolled T2DM in humans. Non-alcoholic fatty liver disease (NAFLD), also described in diabetic humans, results from hepatic triglyceride and cholesterol accumulation associated with rising blood glucose. Protection is afforded by low glycemic load diets rich in certain fibers or polyphenols. Accordingly, the Nile rat provides a unique opportunity to identify the nutritional factors and underlying genetic and molecular mechanisms that characterize human T2DM. PMID- 29463027 TI - The Connexin Mimetic Peptide Gap27 and Cx43-Knockdown Reveal Differential Roles for Connexin43 in Wound Closure Events in Skin Model Systems. AB - In the epidermis, remodelling of Connexin43 is a key event in wound closure. However, controversy between the role of connexin channel and non-channel functions exist. We compared the impact of SiRNA targeted to Connexin43 and the connexin mimetic peptide Gap27 on scrape wound closure rates and hemichannel signalling in adult keratinocytes (AK) and fibroblasts sourced from juvenile foreskin (JFF), human neonatal fibroblasts (HNDF) and adult dermal tissue (ADF). The impact of these agents, following 24 h exposure, on GJA1 (encoding Connexin43), Ki67 and TGF-beta1 gene expression, and Connexin43 and pSmad3 protein expression levels, were examined by qPCR and Western Blot respectively. In all cell types Gap27 (100-100 MUM) attenuated hemichannel activity. In AK and JFF cells, Gap27 (100 nM-100 MUM) enhanced scrape wound closure rates by ~50% but did not influence movement in HNDF or ADF cells. In both JF and AK cells, exposure to Gap27 for 24 h reduced the level of Cx43 protein expression but did not affect the level in ADF and HNDF cells. Connexin43-SiRNA enhanced scrape wound closure in all the cell types under investigation. In HDNF and ADF, Connexin43-SiRNA enhanced cell proliferation rates, with enhanced proliferation also observed following exposure of HDNF to Gap27. By contrast, in JFF and AK cells no changes in proliferation occurred. In JFF cells, Connexin43-SiRNA enhanced TGF-beta1 levels and in JFF and ADF cells both Connexin43-SiRNA and Gap27 enhanced pSmad3 protein expression levels. We conclude that Connexin43 signalling plays an important role in cell migration in keratinocytes and foreskin derived fibroblasts, however, different pathways are evoked and in dermal derived adult and neonatal fibroblasts, inhibition of Connexin43 signalling plays a more significant role in regulating cell proliferation than cell migration. PMID- 29463028 TI - Italian Opuntia ficus-indica Cladodes as Rich Source of Bioactive Compounds with Health-Promoting Properties. AB - Natural by-products, especially phenolic compounds, are in great demand by the nutra-pharmaceutical and biomedical industries. An analytical study was performed to investigate, for the first time, the presence of antioxidant constituents and the corresponding in vitro antioxidant activity in the extract of cladodes from Ficodindia di San Cono (Opuntia ficus-indica) protected designation of origin (PDO). The cladode extracts were analysed for target determination of selected constituents, i.e. beta-polysaccharides and total phenolic content. Moreover, the antioxidant activity of hydro-alcoholic extracts was assessed by means of two different methods: alpha, alpha-diphenyl-beta-picrylhydrazyl (DPPH) free radical scavenging method and ferric reducing antioxidant power (FRAP) assay. An untargeted UHPLC-ESI-QTOF-MS profiling approach was used to depict the phenolic profile of hydro-alcoholic cladode extracts. Interestingly, over 2 g/kg of polyphenols were detected in this matrix, and these compounds were mainly responsible for the antioxidant properties, as shown by the strong correlation between phenolic classes and antioxidant scores. Finally, this study provides basic information on the presence of bioactive compounds and in vitro antioxidant activities in cladode extracts from cactus that might recommend their novel applications at the industrial level in the field of nutraceutical products. PMID- 29463029 TI - Nanoluciferase Reporter Gene System Directed by Tandemly Repeated Pseudo Palindromic NFAT-Response Elements Facilitates Analysis of Biological Endpoint Effects of Cellular Ca2+ Mobilization. AB - NFAT is a cytoplasm-localized hyper-phosphorylated transcription factor that is activated through dephosphorylation by calcineurin, a Ca2+/calmodulin-dependent phosphatase. A non-palindromic NFAT-response element (RE) found in the IL2 promoter region has been commonly used for a Ca2+-response reporter gene system, but requirement of concomitant activation of AP-1 (Fos/Jun) often complicates the interpretation of obtained results. A new nanoluciferase (NanoLuc) reporter gene containing nine-tandem repeats of a pseudo-palindromic NFAT-RE located upstream of the IL8 promoter was designed to monitor Ca2+-induced transactivation activity of NFAT in human embryonic kidney (HEK) 293 cells by measuring luciferase activities of NanoLuc and co-expressed firefly luciferase for normalization. Ionomycin treatment enhanced the relative luciferase activity (RLA), which was suppressed by calcineurin inhibitors. HEK293 cells that stably express human STIM1 and Orai1, components of the store-operated calcium entry (SOCE) machinery, gave a much higher RLA by stimulation with thapsigargin, an inhibitor of sarcoplasmic/endoplamic reticulum Ca2+-ATPase (SERCA). HEK293 cells deficient in a penta-EF-hand Ca2+-binding protein ALG-2 showed a higher RLA value than the parental cells by stimulation with an acetylcholine receptor agonist carbachol. The novel reporter gene system is found to be useful for applications to cell signaling research to monitor biological endpoint effects of cellular Ca2+ mobilization.

AB - This study sought to describe the mental health problems experienced by Korean disaster survivors, using a qualitative research method to provide empirical resources for effective disaster mental health support in Korea. Participants were 16 adults or elderly adults who experienced one or more disasters at least 12 months ago recruited via theoretical sampling. Participants underwent in-depth individual interviews on their disaster experiences, which were recorded and transcribed for qualitative analysis, which followed Strauss and Corbin's (1998) Grounded theory. After open coding, participants' experiences were categorized into 130 codes, 43 sub-categories and 17 categories. The categories were further analyzed in a paradigm model, conditional model and the Disaster Reintegration Model, which proposed potentially effective mental health recovery strategies for disaster survivors, health providers and administrators. To provide effective assistance for mental health recovery of disaster survivors, both personal and public resilience should be promoted while considering both cultural and spiritual elements. PMID- 29463031 TI - Telomere Length Maintenance in Cancer: At the Crossroad between Telomerase and Alternative Lengthening of Telomeres (ALT). AB - Eukaryotic cells undergo continuous telomere shortening as a consequence of multiple rounds of replications. During tumorigenesis, cells have to acquire telomere DNA maintenance mechanisms (TMMs) in order to counteract telomere shortening, to preserve telomeres from DNA damage repair systems and to avoid telomere-mediated senescence and/or apoptosis. For this reason, telomere maintenance is an essential step in cancer progression. Most human tumors maintain their telomeres expressing telomerase, whereas a lower but significant proportion activates the alternative lengthening of telomeres (ALT) pathway. However, evidence about the coexistence of ALT and telomerase has been found both in vivo in the same cancer populations and in vitro in engineered cellular models, making the distinction between telomerase- and ALT-positive tumors elusive. Indeed, after the development of drugs able to target telomerase, the capability for some cancer cells to escape death, switching from telomerase to ALT, was highlighted. Unfortunately, to date, the mechanism underlying the possible switching or the coexistence of telomerase and ALT within the same cell or populations is not completely understood and different factors could be involved. In recent years, different studies have tried to shed light on the complex regulation network that controls the transition between the two TMMs, suggesting a role for embryonic cancer origin, epigenetic modifications, and specific genes activation-both in vivo and in vitro. In this review, we examine recent findings about the cancer-associated differential activation of the two known TMMs and the possible factors implicated in this process. Furthermore, some studies on cancers are also described that did not display any TMM. PMID- 29463032 TI - Comparative Study of the Detection of Chromium Content in Rice Leaves by 532 nm and 1064 nm Laser-Induced Breakdown Spectroscopy. AB - Fast detection of toxic metals in crops is important for monitoring pollution and ensuring food safety. In this study, laser-induced breakdown spectroscopy (LIBS) was used to detect the chromium content in rice leaves. We investigated the influence of laser wavelength (532 nm and 1064 nm excitation), along with the variations of delay time, pulse energy, and lens-to-sample distance (LTSD), on the signal (sensitivity and stability) and plasma features (temperature and electron density). With the optimized experimental parameters, univariate analysis was used for quantifying the chromium content, and several preprocessing methods (including background normalization, area normalization, multiplicative scatter correction (MSC) transformation and standardized normal variate (SNV) transformation were used to further improve the analytical performance. The results indicated that 532 nm excitation showed better sensitivity than 1064 nm excitation, with a detection limit around two times lower. However, the prediction accuracy for both excitation wavelengths was similar. The best result, with a correlation coefficient of 0.9849, root-mean-square error of 3.89 mg/kg and detection limit of 2.72 mg/kg, was obtained using the SNV transformed signal (Cr I 425.43 nm) induced by 532 nm excitation. The results indicate the inspiring capability of LIBS for toxic metals detection in plant materials. PMID- 29463033 TI - Spindle-E Acts Antivirally Against Alphaviruses in Mosquito Cells. AB - Mosquitoes transmit several human- and animal-pathogenic alphaviruses (Togaviridae family). In alphavirus-infected mosquito cells two different types of virus-specific small RNAs are produced as part of the RNA interference response: short-interfering (si)RNAs and PIWI-interacting (pi)RNAs. The siRNA pathway is generally thought to be the main antiviral pathway. Although an antiviral activity has been suggested for the piRNA pathway its role in host defences is not clear. Knock down of key proteins of the piRNA pathway (Ago3 and Piwi5) in Aedesaegypti-derived cells reduced the production of alphavirus chikungunya virus (CHIKV)-specific piRNAs but had no effect on virus replication. In contrast, knock down of the siRNA pathway key protein Ago2 resulted in an increase in virus replication. Similar results were obtained when expression of Piwi4 was silenced. Knock down of the helicase Spindle-E (SpnE), an essential co factor of the piRNA pathway in Drosophila melanogaster, resulted in increased virus replication indicating that SpnE acts as an antiviral against alphaviruses such as CHIKV and the related Semliki Forest virus (SFV). Surprisingly, this effect was found to be independent of the siRNA and piRNA pathways in Ae. aegypti cells and specific for alphaviruses. This suggests a small RNA-independent antiviral function for this protein in mosquitoes. PMID- 29463034 TI - Chronic Ketogenic Low Carbohydrate High Fat Diet Has Minimal Effects on Acid-Base Status in Elite Athletes. AB - Although short (up to 3 days) exposure to major shifts in macronutrient intake appears to alter acid-base status, the effects of sustained (>1 week) interventions in elite athletes has not been determined. Using a non-randomized, parallel design, we examined the effect of adaptations to 21 days of a ketogenic low carbohydrate high fat (LCHF) or periodized carbohydrate (PCHO) diet on pre- and post-exercise blood pH, and concentrations of bicarbonate (HCO3-) and lactate (La-) in comparison to a high carbohydrate (HCHO) control. Twenty-four (17 male and 7 female) elite-level race walkers completed 21 days of either LCHF (n = 9), PCHO (n = 7), or HCHO (n = 8) under controlled diet and training conditions. At baseline and post-intervention, blood pH, blood [HCO3-], and blood [La-] were measured before and after a graded exercise test. Net endogenous acid production (NEAP) over the previous 48-72 h was also calculated from monitored dietary intake. LCHF was not associated with significant differences in blood pH, [HCO3 ], or [La-], compared with the HCHO diet pre- or post-exercise, despite a significantly higher NEAP (mEq.day-1) (95% CI = [10.44; 36.04]). Our results indicate that chronic dietary interventions are unlikely to influence acid-base status in elite athletes, which may be due to pre-existing training adaptations, such as an enhanced buffering capacity, or the actions of respiratory and renal pathways, which have a greater influence on regulation of acid-base status than nutritional intake. PMID- 29463035 TI - Nanomechanical Phenotype of Melanoma Cells Depends Solely on the Amount of Endogenous Pigment in the Cells. AB - Cancer cells have unique nanomechanical properties, i.e., they behave as if they were elastic. This property of cancer cells is believed to be one of the main reasons for their facilitated ability to spread and metastasize. Thus, the so called nanomechanical phenotype of cancer cells is viewed as an important indicator of the cells' metastatic behavior. One of the most highly metastatic cancer cells are melanoma cells, which have a very unusual property: they can synthesize the pigment melanin in large amounts, becoming heavily pigmented. So far, the role of melanin in melanoma remains unclear, particularly the impact of the pigment on metastatic behavior of melanoma cells. Importantly, until recently the potential mechanical role of melanin in melanoma metastasis was completely ignored. In this work, we examined melanoma cells isolated from hamster tumors containing endogenous melanin pigment. Applying an array of advanced microscopy and spectroscopy techniques, we determined that melanin is the dominating factor responsible for the mechanical properties of melanoma cells. Our results indicate that the nanomechanical phenotype of melanoma cells may be a reliable marker of the cells' metastatic behavior and point to the important mechanical role of melanin in the process of metastasis of melanoma. PMID- 29463036 TI - Physicochemical and Rheological Properties of a Dairy Dessert, Enriched with Chickpea Flour. AB - Dairy desserts are complex mixtures and matrices including main components such as milk, sugar, starch, hydrocolloids, colorants and flavors, with a proteinaceous structure; they are widely consumed and present a semisolid consistency. In this work, the physicochemical and rheological properties of a dairy dessert with the addition of chickpea flour (raw and cooked, at four concentrations) were studied to determine the effect of the flour. The results indicated that luminosity (L*: 62.75-83.29), pH (6.35-7.11) and acidity (1.56 3.56) changed with the type of flour. The flow properties of the custards exhibited a non-Newtonian behavior that was well fitted by three flow models. The studied custard systems were stored for twelve days at 4 degrees C. The physicochemical and flow properties of the custards changed notably as a function of flour addition and storage time. From all samples, only four were analyzed with oscillatory tests, showing their mechanical spectra with elastic behavior. The dessert texture was also measured, founding that those formulated with Blanco Noroeste chickpea flour exhibited the highest values of hardness (0.356-0.391 Newton (N)) through the twelve days. It can be concluded that those custard systems with the highest content of flour presented a very good response as a potential new dairy product. PMID- 29463037 TI - Antioxidant and Anti-Osteoporosis Activities of Chemical Constituents of the Stems of Zanthoxylum piperitum. AB - Two new lignans, zanthoxyloside C (1) and zanthoxyloside D (2), together with nine known compounds comprising lignans (3-5), flavonoids (6-8), and phenolics (9 11), were isolated from the methanol extract of the stems of Zanthoxylum piperitum. All isolates were evaluated for their antioxidant and anti osteoporotic activities using oxygen radical absorbance capacity (ORAC), cupric reducing antioxidant capacity (CUPRAC), and tartrate-resistant acid phosphatase (TRAP) assays. Compounds 7-10 showed peroxyl radical-scavenging capacities and 4, 6-7, and 9 showed reducing capacities. Moreover, compounds 3, 6-9, and 11 significantly suppressed TRAP activities. These results indicated that the stems of Z. piperitum could be an excellent source for natural antioxidant and anti osteoporosis. PMID- 29463038 TI - Presence of TERT Promoter Mutations is a Secondary Event and Associates with Elongated Telomere Length in Myxoid Liposarcomas. AB - The occurrence of TERT promoter mutations has been well described in soft tissue sarcomas (STS). However, the biological role of these mutations as well as their impact on telomere length in STS is still unclear. We analyzed 116 patient samples diagnosed with 22 distinct histological subtypes of bone and STS for the occurrence of TERT promoter mutations by Sanger sequencing. We observed TERT promoter mutations at an overall frequency of 9.5% distributed over 7 different sarcoma subtypes. Except for one chondrosarcoma case harboring a C250T mutation, all other mutations were detected at location C228T. By far the far highest frequency of TERT promoter mutations was found in myxoid liposarcoma (MLS) (4 out of 9 cases studied, i.e., 44%). Assessment of telomere length from tumor biopsies revealed that TERT promoter-mutated MLSs had significantly fewer shortened telomeres in comparison to TERT wildtype MLSs. Based on the frequency of TERT promoter mutations and the elongated telomere length in mutated compared to wildtype MLS, we hypothesize that occurrence of TERT promoter mutations has a pivotal role in the disease progression as a secondary genetic event at a time when tumor cells face the need for telomere elongation to allow further proliferation. PMID- 29463039 TI - The Significance of MMP-1 in EGFR-TKI-Resistant Lung Adenocarcinoma: Potential for Therapeutic Targeting. AB - Epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) resistance is one of the most important problems in lung cancer therapy. Lung adenocarcinoma with EGFR-TKI resistance was reported to have higher abilities of invasion and migration than cancers sensitive to EGFR-TKI, but the function of matrix metalloproteinases (MMPs) has not been explored in EGFR-TKI-resistant lung adenocarcinoma. This study aims to clarify the significance of MMP-1 in EGFR-TKI resistant lung adenocarcinoma. From the results of in vitro studies of migration and invasion assays using EGFR-TKI-sensitive and -resistant cell lines and phosphorylation antibody arrays using EGF and rapamycin, we first demonstrate that overexpression of MMP-1, which might follow activation of a mammalian target of rapamycin (mTOR) pathway, plays an important role in the migration and invasion abilities of EGFR-TKI-resistant lung adenocarcinoma. Additionally, immunohistochemical studies using 89 cases of lung adenocarcinoma demonstrate that high expression of MMP-1 is significantly correlated with poor prognosis and factors such as smoking history and the subtype of invasive mucinous adenocarcinoma. These are consistent with the results of this in vitro study. To conclude, this study provides insights into the development of a possible alternative therapy manipulating MMP-1 and the mTOR signaling pathway in EGFR-TKI resistant lung adenocarcinoma. PMID- 29463040 TI - Structural Insights into sigma1 Receptor Interactions with Opioid Ligands by Molecular Dynamics Simulations. AB - Despite considerable advances over the past years in understanding the mechanisms of action and the role of the sigma1 receptor, several questions regarding this receptor remain unanswered. This receptor has been identified as a useful target for the treatment of a diverse range of diseases, from various central nervous system disorders to cancer. The recently solved issue of the crystal structure of the sigma1 receptor has made elucidating the structure-activity relationship feasible. The interaction of seven representative opioid ligands with the crystal structure of the sigma1 receptor (PDB ID: 5HK1) was simulated for the first time using molecular dynamics (MD). Analysis of the MD trajectories has provided the receptor-ligand interaction fingerprints, combining information on the crucial receptor residues and frequency of the residue-ligand contacts. The contact frequencies and the contact maps suggest that for all studied ligands, the hydrophilic (hydrogen bonding) interactions with Glu172 are an important factor for the ligands' affinities toward the sigma1 receptor. However, the hydrophobic interactions with Tyr120, Val162, Leu105, and Ile124 also significantly contribute to the ligand-receptor interplay and, in particular, differentiate the action of the agonistic morphine from the antagonistic haloperidol. PMID- 29463042 TI - Promotion of Vascular Morphogenesis of Endothelial Cells Co-Cultured with Human Adipose-Derived Mesenchymal Stem Cells Using Polycaprolactone/Gelatin Nanofibrous Scaffolds. AB - New blood vessel formation is essential for tissue regeneration to deliver oxygen and nutrients and to maintain tissue metabolism. In the field of tissue engineering, in vitro fabrication of new artificial vessels has been a longstanding challenge. Here we developed a technique to reconstruct a microvascular system using a polycaprolactone (PCL)/gelatin nanofibrous structure and a co-culture system. Using a simple electrospinning process, we fabricated three-dimensional mesh scaffolds to support the sprouting of human umbilical vein endothelial cells (HUVECs) along the electrospun nanofiber. The co-culture with adipose-derived mesenchymal stem cells (ADSCs) supported greater sprouting of endothelial cells (ECs). In a two-dimensional culture system, angiogenic cell assembly produced more effective direct intercellular interactions and paracrine signaling from ADSCs to assist in the vascular formation of ECs, compared to the influence of growth factor. Although vascular endothelial growth factor and sphingosine-1-phosphate were present during the culture period, the presence of ADSCs was the most important factor for the construction of a cell-assembled structure in the two-dimensional culture system. On the contrary, HUVECs co cultured on PCL/gelatin nanofiber scaffolds produced mature and functional microvessel and luminal structures with a greater expression of vascular markers, including platelet endothelial cell adhesion molecule-1 and podocalyxin. Furthermore, both angiogenic factors and cellular interactions with ADSCs through direct contact and paracrine molecules contributed to the formation of enhanced engineered blood vessel structures. It is expected that the co-culture system of HUVECs and ADSCs on bioengineered PCL/gelatin nanofibrous scaffolds will promote robust and functional microvessel structures and will be valuable for the regeneration of tissue with restored blood vessels. PMID- 29463041 TI - The Antioxidant Content and Protective Effect of Argan Oil and Syzygium aromaticum Essential Oil in Hydrogen Peroxide-Induced Biochemical and Histological Changes. AB - Oxidative stress is an important etiology of chronic diseases and many studies have shown that natural products might alleviate oxidative stress-induced pathogenesis. The study aims to evaluate the effect of Argan oil and Syzygium aromaticum essential oil on hydrogen peroxide (H2O2)-induced liver, brain and kidney tissue toxicity as well as biochemical changes in wistar rats. The antioxidant content of Argan oil and Syzygium aromaticum essential oil was studied with the use of gas chromatography. The animals received daily by gavage, for 21 days, either distilled water, Syzygium aromaticum essential oil, Argan oil, H2O2 alone, H2O2 and Syzygium aromaticum essential oil, or H2O2 and Argan oil. Blood samples were withdrawn on day 21 for the biochemical blood tests, and the kidney, liver and brain tissue samples were prepared for histopathology examination. The results showed that the content of antioxidant compounds in Syzygium aromaticum essential oil is higher than that found in Argan oil. H2O2 increased level of blood urea, liver enzymes, total cholesterol, Low Density Lipoprotein (LDL-C), Triglycerides (TG) and Very Low Density Lipoprotein (VLDL), and decreased the total protein, albumin and High Density Lipoprotein-cholesterol (HDL-C). There was no significant effect on blood electrolyte or serum creatinine. The histopathology examination demonstrated that H2O2 induces dilatation in the central vein, inflammation and binucleation in the liver, congestion and hemorrhage in the brain, and congestion in the kidney. The H2O2 induced histopathological and biochemical changes have been significantly alleviated by Syzygium aromaticum essential oil or Argan oil. It is concluded that the Argan oil and especially the mixture of Argan oil with Syzygium aromaticum essential oil can reduce the oxidative damage caused by H2O2, and this will pave the way to investigate the protective effects of these natural substances in the diseases attributed to the high oxidative stress. PMID- 29463043 TI - Non-Culture Diagnostics for Invasive Candidiasis: Promise and Unintended Consequences. AB - Blood cultures are positive for Candida species in < 50% and < 20% of hematogenously disseminated and intra-abdominal candidiasis, respectively. Non culture tests such as mannan, anti-mannan antibody, Candida albicans germ tube antibody (CAGTA), 1,3-beta-d-glucan (BDG), the T2Candida nanodiagnostic panel, and polymerase chain reaction (PCR) are available for clinical use, but their roles in patient care are uncertain. Sensitivity/specificity of combined mannan/anti-mannan, BDG, T2Candida and PCR for candidemia are ~80%/80%, ~80%/80%, ~90%/98%, and ~90%/90%, respectively. Limited data for intra-abdominal candidiasis suggest CAGTA, BDG sensitivity/specificity of ~65%/75% and PCR sensitivity of ~85-90%. PCR specificity has varied widely for intra-abdominal candidiasis (33-97%), and T2Candida data are lacking. Tests will be useful if restricted to cases in which positive and negative predictive values (PPVs, NPVs) differ in a clinically meaningful way from the pre-test likelihood of invasive candidiasis. In some patients, PPVs are sufficient to justify antifungal treatment, even if blood cultures are negative. In most patients, NPVs of each test are excellent, which may support decisions to withhold antifungal therapy. If test results are not interpreted judiciously, non-culture diagnostics may have unintended consequences for stewardship and infection prevention programs. In particular, discrepant non-culture test-positive/culture-negative results may promote inappropriate antifungal treatment of patients who are unlikely to have candidiasis, and lead to spurious reporting of hospital-acquired infections. In conclusion, non-culture Candida diagnostics have potential to advance patient care, but this promise will be realized only if users understand tests' strengths and limitations, and plan proactively for how best to employ them at their hospitals. PMID- 29463045 TI - Tunable Bandgap and Optical Properties of Black Phosphorene Nanotubes. AB - Black phosphorus (BP), a new two-dimensional material, has been the focus of scientists' attention. BP nanotubes have potential in the field of optoelectronics due to their low-dimensional effects. In this work, the bending strain energy, electronic structure, and optical properties of BP nanotubes were investigated by using the first-principles method based on density functional theory. The results show that these properties are closely related to the rolling direction and radius of the BP nanotube. All the calculated BP nanotube properties show direct bandgaps, and the BP nanotubes with the same rolling direction express a monotone increasing trend in the value of bandgap with a decrease in radius, which is a stacking effect of the compression strain on the inner atoms and the tension strain on the outer atoms. The bending strain energy of the zigzag phosphorene nanotubes (zPNTs) is higher than that of armchair phosphorene nanotubes (aPNT) with the same radius of curvature due to the anisotropy of the BP's structure. The imaginary part of the dielectric function, the absorption range, reflectivity, and the imaginary part of the refractive index of aPNTs have a wider range than those of zPNTs, with higher values overall. As a result, tunable BP nanotubes are suitable for optoelectronic devices, such as lasers and diodes, which function in the infrared and ultra violet regions, and for solar cells and photocatalysis. PMID- 29463046 TI - A Novel Hard Decision Based Simultaneous Target Tracking and Classification Approach. AB - Methods dealing with the problem of Joint Tracking and Classification (JTC) are abundant, among which Simultaneous Tracking and Classification (STC) provides a modularized scheme solving tracking and classification subproblems simultaneously. However, there is no explicit hard decision on the class label but only soft decision (class probability) is provided. This does not fit many practical cases, in which a hard decision is urgently needed. To solve this problem, this paper proposes a Hard decision-based STC (HSTC) method. HSTC takes all the decision error rate, timeliness, and estimation error into account. Specifically, for decision, the sequential probability ratio test is adopted due to its nice properties and also the adaptability to our situation. For estimation, by utilizing the two-way information exchange between the tracker and the classifier, we propose flexible three tracking schemes related to decision. The HSTC tracking result is divided into three parts according to the time of making the hard decision. In general, the proposed HSTC method takes advantage of both SPRT and STC. Finally, two illustrative JTC examples with hard decision verify the effectiveness of the the proposed HSTC method. They show that HSTC can meet the demand of the problem, and also has the performance superiority in both decision and estimation. PMID- 29463044 TI - The Role of the Estrogen Pathway in the Tumor Microenvironment. AB - Estrogen receptors are broadly expressed in many cell types involved in the innate and adaptive immune responses, and differentially regulate the production of cytokines. While both genomic and non-genomic tumor cell promoting mechanisms of estrogen signaling are well characterized in multiple carcinomas including breast, ovarian, and lung, recent investigations have identified a potential immune regulatory role of estrogens in the tumor microenvironment. Tumor immune tolerance is a well-established mediator of oncogenesis, with increasing evidence indicating the importance of the immune response in tumor progression. Immune based therapies such as antibodies that block checkpoint signals have emerged as exciting therapeutic approaches for cancer treatment, offering durable remissions and prolonged survival. However, only a subset of patients demonstrate clinical response to these agents, prompting efforts to elucidate additional immunosuppressive mechanisms within the tumor microenvironment. Evidence drawn from multiple cancer types, including carcinomas traditionally classified as non immunogenic, implicate estrogen as a potential mediator of immunosuppression through modulation of protumor responses independent of direct activity on tumor cells. Herein, we review the interplay between estrogen and the tumor microenvironment and the clinical implications of endocrine therapy as a novel treatment strategy within immuno-oncology. PMID- 29463047 TI - Human Intrinsic Factor Expression for Bioavailable Vitamin B12 Enrichment in Microalgae. AB - Dietary supplements and functional foods are becoming increasingly popular complements to regular diets. A recurring ingredient is the essential cofactor vitamin B12 (B12). Microalgae are making their way into the dietary supplement and functional food market but do not produce B12, and their B12 content is very variable. In this study, the suitability of using the human B12-binding protein intrinsic factor (IF) to enrich bioavailable B12 using microalgae was tested. The IF protein was successfully expressed from the nuclear genome of the model microalga Chlamydomonasreinhardtii and the addition of an N-terminal ARS2 signal peptide resulted in efficient IF secretion to the medium. Co-abundance of B12 and the secreted IF suggests the algal produced IF protein is functional and B12 binding. Utilizing IF expression could be an efficient tool to generate B12 enriched microalgae in a controlled manner that is suitable for vegetarians and, potentially, more bioavailable for humans. PMID- 29463048 TI - Trifluoromethyl Boron Dipyrromethene Derivatives as Potential Photosensitizers for Photodynamic Therapy. AB - In this study, two novel boron dipyrromethene-based photosensitizers (BDP3 and BDP6) substituted with three or six trifluoromethyl groups have been synthesized and characterized with various spectroscopic methods, and their photo-physical, photo-chemical, and photo-biological properties have also been explored. The two photosensitizers are highly soluble and remain nonaggregated in N,N dimethylformamide as shown by the intense and sharp Q-band absorption. Under red light irradiation (lambda = 660 nm, 1.5 J/cm2), both photosensitizers show high and comparable cytotoxicity towards HepG2 human hepatocarcinoma and HeLa human cervical carcinoma cells with IC50 values of 0.42-0.49 MUM. The high photocytotoxicity of BDP3 and BDP6 can be due to their high cellular uptake and low aggregation tendency in biological media, which result in a high efficiency to generate reactive oxygen species inside the cells. Confocal laser fluorescence microscopic studies indicate that they have superior selective affinities to the mitochondria and lysosomes of HepG2 and HeLa cells. The results show that these two trifluoromethyl boron dipyrromethene derivatives are potential anticancer agents for photodynamic therapy. PMID- 29463049 TI - The Anti-Cancer Effects of Frondoside A. AB - Frondoside A is a triterpenoid glycoside from the Atlantic Sea Cucumber, Cucumariafrondosa. Frondoside A has a broad spectrum of anti-cancer effects, including induction of cellular apoptosis, inhibition of cancer cell growth, migration, invasion, formation of metastases, and angiogenesis. In cell lines and animal models studied to date, the anti-cancer effects of the compound are seen in all solid cancers, lymphomas, and leukemias studied to date. These effects appear to be due to potent inhibition of p21-activated kinase 1 (PAK1), which is up-regulated in many cancers. In mouse models, frondoside A has synergistic effects with conventional chemotherapeutic agents, such as gemcitabine, paclitaxel, and cisplatin. Frondoside A administration is well-tolerated. No side effects have been reported and the compound has no significant effects on body weight, blood cells, or on hepatic and renal function tests after long-term administration. Frondoside A may be valuable in the treatment of malignancies, either as a single agent or in combination with other therapeutic modalities. PMID- 29463051 TI - Evidence of Adaptation to Recent Changes in Atmospheric CO2 in Four Weedy Species. AB - Seeds of three C3 and one C4 annual weedy species were collected from agricultural fields in Beltsville, Maryland in 1966 and 2006, when atmospheric CO2 concentrations averaged about 320 and 380 mol mol-1, respectively. Plants from each collection year were grown over a range of CO2 concentrations to test for adaptation of these weedy species to recent changes in atmospheric CO2. In all three of the C3 species, the increase in CO2 concentration from 320 mol mol-1 to 380 mol mol-1 increased total dry mass at 24 days in plants from seeds collected in 2006, but not in plants from seeds collected in 1966. Shoot and seed dry mass at maturity was greater at the higher growth CO2 in plants collected in 2006 than in 1966 in two of the species. Down-regulation of photosynthetic carboxylation capacity during growth at high CO2 was less in the newer seed lots than in the older in two of the species. Overall, the results indicate that adaptation to recent changes in atmospheric CO2 has occurred in some of these weedy species. PMID- 29463050 TI - Associations between Ambient Particulate Matter and Nitrogen Dioxide and Chronic Obstructive Pulmonary Diseases in Adults and Effect Modification by Demographic and Lifestyle Factors. AB - This study was undertaken to investigate the associations between chronic exposure to particulate matter of medium aerodynamic diameter <=10 or <=2.5 um (PM10 or PM2.5) and nitrogen dioxide (NO2) levels and lung function and to examine a possible change in these relationships by demographic and lifestyle factors. Chronic obstructive pulmonary disease (COPD) was defined using the Global Initiative for COPD criteria (forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC) of <70%). Associations of lung function and COPD with PM10 or PM2.5 or NO2 were examined using linear and logistic regression analyses among 1264 Korean adults. The highest tertiles of PM2.5 (>=37.1 MUg/m3) and NO2 (>=53.8 MUg/m3) exposure were significantly associated with COPD (highest versus lowest tertile of PM2.5: adjusted odds ratio (OR) = 1.79, 95% CI: 1.02 3.13; highest versus lowest tertile of NO2: adjusted OR = 1.83, 95% CI: 1.04 3.21). A 10 MUg/m3 increase in PM10 concentration was associated with a 1.85 L (95% CI -3.65 to -0.05) decrease in FEV1 and a 1.73 L (95% CI -3.35 to -0.12) decrease in FVC, with the strongest negative association among older people and those with less education. Reduced lung function was associated with PM2.5 exposure in subjects with no physical activity. This study provides evidence that exposure to ambient air pollution has adverse effects on lung function in adults.

To encourage employees to lead a less sedentary life, the Hanze University started a health promotion program. One of the interventions in the program was the use of an activity tracker to record participants' daily step count. The daily step count served as input for a fortnightly coaching session. In this paper, we investigate the possibility of automating part of the coaching procedure on physical activity by providing personalized feedback throughout the day on a participant's progress in achieving a personal step goal. The gathered step count data was used to train eight different machine learning algorithms to make hourly estimations of the probability of achieving a personalized, daily steps threshold. In 80% of the individual cases, the Random Forest algorithm was the best performing algorithm (mean accuracy = 0.93, range = 0.88-0.99, and mean F1-score = 0.90, range = 0.87-0.94). To demonstrate the practical usefulness of these models, we developed a proof-of-concept Web application that provides personalized feedback about whether a participant is expected to reach his or her daily threshold. We argue that the use of machine learning could become an invaluable asset in the process of automated personalized coaching. The individualized algorithms allow for predicting physical activity during the day and provides the possibility to intervene in time. PMID- 29463053 TI - Nutritional Composition and Antioxidant Properties of the Fruits of a Chinese Wild Passiflora foetida. AB - The aim of this work was to evaluate the main nutrients and their antioxidant properties of a Chinese wild edible fruit, Passiflora foetida, collected from the ecoregion of Hainan province, China. The analytical results revealed that P. foetida fruits were rich in amino acids (1097 mg/100 g in total), minerals (595.75 mg/100 g in total), and unsaturated fatty acids (74.18 g/100 g in total fat). The lyophilized powder of edible portion contained the higher polyphenols content than the inedible portion powder. The UPLC-Q-TOF-MSE analysis of the extractable and non-extractable phenolics indicated the presence of 65 compounds including 39 free phenolics, 14 insoluble-glycoside-phenolics, and 22 insoluble ester-phenolics. In addition, the non-extractable phenolics obtained by alkali hydrolysis showed significant antioxidant activities by/through DPPH and ABTS radical scavenging. These findings of P. foetida fruits, for the first time, suggest that these polyphenol-rich fruits may have potential nutraceutical efficacies.

AB - This study presents two sensitive fluorescent assays for sensing heparin on the basis of the electrostatic interaction between heparin and Naja naja atra cardiotoxin 3 (CTX3). Owing to CTX3-induced folded structure of an adenosine based molecular beacon (MB) or a DNA aptamer against CTX3, a reduction in the fluorescent signal of the aptamer or MB 5'-end labeled with carboxyfluorescein (FAM) and 3'-end labeled with 4-([4-(dimethylamino)phenyl]azo)-benzoic acid (DABCYL) was observed upon the addition of CTX3. The presence of heparin and formation of the CTX3-heparin complex caused CTX3 detachment from the MB or aptamer, and restoration of FAM fluorescence of the 5'-FAM-and-3'-DABCYL-labeled MB and aptamer was subsequently noted. Moreover, the detection of heparin with these CTX3-aptamer and CTX3-MB sensors showed high sensitivity and selectivity toward heparin over chondroitin sulfate and hyaluronic acid regardless of the presence of plasma. The limit of detection for heparin in plasma was determined to be 16 ng/mL and 15 ng/mL, respectively, at a signal-to-noise ratio of 3. This study validates the practical utility of the CTX3-aptamer and CTX3-MB systems for determining the concentration of heparin in a biological matrix.

AB - Antibiotic resistance poses an important threat to global public health and has become a challenge to modern medicine. The occurrence of antibiotic-resistant bacteria in a broad range of foods has led to a growing concern about the impact that food may have as a reservoir of antibiotic resistance genes. Considering Minas Frescal Cheese (MFC)-a typical Brazilian white soft cheese-and its economic and cultural values, in this study, medically relevant antimicrobial-resistance genetic markers (AR genes) were screened, and the occurrence of integrons were evaluated in manufactured MFC using culture-independent approaches. Through a fingerprinting analysis, the tested MFCs were brand-clustered, indicating reproducibility along the production chain. A common core of resistance markers in all brands evaluated and related antimicrobials such as beta-lactams, tetracyclines, quinolones, and sulfonamide was detected. Several other markers, including efflux pumps and aminoglycosides-resistance were distributed among brands. Class 1 and 2 integrons were observed, respectively, in 77% and 97% of the samples. The presence of AR genes is of special interest due to their clinical relevance. Taken together, the data may suggest that the production chain of MFC might contribute to the spread of putative drug-resistant bacteria, which could greatly impact human health. Furthermore, detection of class 1 and class 2 integrons in MFC has led to discussions about resistance gene spread in this traditional cheese, providing evidence of potential horizontal transfer of AR genes to human gut microbiota. PMID- 29463056 TI - A Comparative Assessment of Biological Effects and Chemical Profile of Italian Asphodeline lutea Extracts. AB - The present study aims to highlight the therapeutic potential of Asphodeline lutea (AL), a wild edible plant of the Mediterranean diet. Roots, aerial parts, and flowers of AL at two different phenological stages were collected from three locations in Italy. The inhibitory activities of extracts on strategic enzymes linked to human diseases were assessed. The antioxidant properties were evaluated in vitro, using six standard bioassays. The phenolic and anthraquinone profiles were also established using HPLC-PDA. Zinc, cadmium, lead, and copper contents were also determined. All the samples inhibited acetylcholinesterase (from 1.51 to 2.20 mg GALAEs/g extract), tyrosinase (from 7.50 to 25.3 mg KAEs/g extract), and alpha-amylase (from 0.37 to 0.51 mmol ACAEs/g extract). Aloe-emodin and physcion were present in all parts, while rhein was not detected. The phenolic profile and the heavy metals composition of specimens gathered from three different regions of Italy were different. It can be argued that samples collected near the street can contain higher concentrations of heavy metals. The experimental data confirm that the A. lutea species could be considered as a potential source of bioactive metabolites, and its consumption could play a positive and safe role in human health maintenance. PMID- 29463058 TI - Biosorption: An Interplay between Marine Algae and Potentially Toxic Elements-A Review. AB - In recent decades, environmental pollution has emerged as a core issue, around the globe, rendering it of fundamental concern to eco-toxicologists, environmental biologists, eco-chemists, pathologists, and researchers from other fields. The dissolution of polluting agents is a leading cause of environmental pollution of all key spheres including the hydrosphere, lithosphere, and biosphere, among others. The widespread occurrence of various pollutants including toxic heavy metals and other emerging hazardous contaminants is a serious concern. With increasing scientific knowledge, socioeconomic awareness, human health problems, and ecological apprehensions, people are more concerned about adverse health outcomes. Against this background, several removal methods have been proposed and implemented with the aim of addressing environmental pollution and sustainable and eco-friendly development. Among them, the biosorption of pollutants using naturally inspired sources, e.g., marine algae, has considerable advantages. In the past few years, marine algae have been extensively studied due to their natural origin, overall cost-effective ratio, and effectiveness against a broader pollutant range; thus, they are considered a potential alternative to the conventional methods used for environmental decontamination. Herein, an effort has been made to highlight the importance of marine algae as naturally inspired biosorbents and their role in biosorption. Biosorption mechanisms and factors affecting biosorption activities are also discussed in this review. The utilization of marine algae as a biosorbent for the removal of numerous potentially toxic elements has also been reviewed. PMID- 29463057 TI - Alternative Splicing of Transcription Factors Genes in Muscle Physiology and Pathology. AB - Skeletal muscle formation is a multi-step process that is governed by complex networks of transcription factors. The regulation of their functions is in turn multifaceted, including several mechanisms, among them alternative splicing (AS) plays a primary role. On the other hand, altered AS has a role in the pathogenesis of numerous muscular pathologies. Despite these premises, the causal role played by the altered splicing pattern of transcripts encoding myogenic transcription factors in neuromuscular diseases has been neglected so far. In this review, we systematically investigate what has been described about the AS patterns of transcription factors both in the physiology of the skeletal muscle formation process and in neuromuscular diseases, in the hope that this may be useful in re-evaluating the potential role of altered splicing of transcription factors in such diseases. PMID- 29463059 TI - Glutamine Synthetase: Localization Dictates Outcome. AB - Glutamine synthetase (GS) is the adenosine triphosphate (ATP)-dependent enzyme that catalyses the synthesis of glutamine by condensing ammonium to glutamate. In the circulatory system, glutamine carries ammonia from muscle and brain to the kidney and liver. In brain reduction of GS activity has been suggested as a mechanism mediating neurotoxicity in neurodegenerative disorders. In cancer, the delicate balance between glutamine synthesis and catabolism is a critical event. In vitro evidence, confirmed in vivo in some cases, suggests that reduced GS activity in cancer cells associates with a more invasive and aggressive phenotype. However, GS is known to be highly expressed in cells of the tumor microenvironment, such as fibroblasts, adipocytes and immune cells, and their ability to synthesize glutamine is responsible for the acquisition of protumoral phenotypes. This has opened a new window into the complex scenario of the tumor microenvironment, in which the balance of glutamine consumption versus glutamine synthesis influences cellular function. Since GS expression responds to glutamine starvation, a lower glutamine synthesizing power due to the absence of GS in cancer cells might apply a metabolic pressure on stromal cells. This event might push stroma towards a GS-high/protumoral phenotype. When referred to stromal cells, GS expression might acquire a 'bad' significance to the point that GS inhibition might be considered a conceivable strategy against cancer metastasis. PMID- 29463060 TI - Chitin Oligosaccharide Modulates Gut Microbiota and Attenuates High-Fat-Diet Induced Metabolic Syndrome in Mice. AB - Gut microbiota has been proved to be an indispensable link between nutrient excess and metabolic syndrome, and chitin oligosaccharide (NACOS) has displayed therapeutic effects on multiple diseases such as cancer and gastritis. In this study, we aim to confirm whether NACOS can ameliorate high-fat diet (HFD)-induced metabolic syndrome by rebuilding the structure of the gut microbiota community. Male C57BL/6J mice fed with HFD were treated with NACOS (1 mg/mL) in drinking water for five months. The results indicate that NACOS improved glucose metabolic disorder in HFD-fed mice and suppressed mRNA expression of the protein regulators related to lipogenesis, gluconeogenesis, adipocyte differentiation, and inflammation in adipose tissues. Additionally, NACOS inhibited the destruction of the gut barrier in HFD-treated mice. Furthermore, 16S ribosome RNA sequencing of fecal samples demonstrates that NACOS promoted the growth of beneficial intestinal bacteria remarkably and decreased the abundance of inflammogenic taxa. In summary, NACOS partly rebuilt the microbial community and improved the metabolic syndrome of HFD-fed mice. These data confirm the preventive effects of NACOS on nutrient excess-related metabolic diseases. PMID- 29463062 TI - Palliative Care for Children in Hospital: Essential Roles. AB - Palliative care for children in pediatric hospitals is a vital part of the network of services supporting children with severe illness. This has been recognized, with a trend over the past decade for an increased number of pediatric palliative care (PPC) services established in pediatric hospitals. The inpatient team is in the unique position of influencing the early identification of children and their families, across the age and diagnostic spectrum, which could benefit from palliative care. These services have an opportunity to influence the integration of the palliative approach throughout the hospital, and in so doing, have the capacity to improve many aspects of care, including altering an increasingly futile and burdensome treatment trajectory, and ensuring improved symptom (physical and psychological) management. PMID- 29463061 TI - Wnt Signaling and Its Impact on Mitochondrial and Cell Cycle Dynamics in Pluripotent Stem Cells. AB - The core transcriptional network regulating stem cell self-renewal and pluripotency remains an intense area of research. Increasing evidence indicates that modified regulation of basic cellular processes such as mitochondrial dynamics, apoptosis, and cell cycle are also essential for pluripotent stem cell identity and fate decisions. Here, we review evidence for Wnt regulation of pluripotency and self-renewal, and its connections to emerging features of pluripotent stem cells, including (1) increased mitochondrial fragmentation, (2) increased sensitivity to cell death, and (3) shortened cell cycle. We provide a general overview of the stem cell-specific mechanisms involved in the maintenance of these uncharacterized hallmarks of pluripotency and highlight potential links to the Wnt signaling pathway. Given the physiological importance of stem cells and their enormous potential for regenerative medicine, understanding fundamental mechanisms mediating the crosstalk between Wnt, organelle-dynamics, apoptosis, and cell cycle will be crucial to gain insight into the regulation of stemness. PMID- 29463064 TI - Devising Mobile Sensing and Actuation Infrastructure with Drones. AB - Vast applications and services have been enabled as the number of mobile or sensing devices with communication capabilities has grown. However, managing the devices, integrating networks or combining services across different networks has become a new problem since each network is not directly connected via back-end core networks or servers. The issue is and has been discussed especially in wireless sensor and actuator networks (WSAN). In such systems, sensors and actuators are tightly coupled, so when an independent WSAN needs to collaborate with other networks, it is difficult to adequately combine them into an integrated infrastructure. In this paper, we propose drone-as-a-gateway (DaaG), which uses drones as mobile gateways to interconnect isolated networks or combine independent services. Our system contains features that focus on the service being provided in the order of importance, different from an adaptive simple mobile sink system or delay-tolerant system. Our simulation results have shown that the proposed system is able to activate actuators in the order of importance of the service, which uses separate sensors' data, and it consumes almost the same time in comparison with other path-planning algorithms. Moreover, we have implemented DaaG and presented results in a field test to show that it can enable large-scale on-demand deployment of sensing and actuation infrastructure or the Internet of Things (IoT). PMID- 29463065 TI - Paediatric Palliative Care in Resource-Poor Countries. AB - There is a great need for paediatric palliative care (PPC) services globally, but access to services is lacking in many parts of the world, particularly in resource-poor settings. Globally it is estimated that 21.6 million children need access to palliative care, with 8.2 needing specialist services. PC has been identified as important within the global health agenda e.g., within universal health coverage, and a recent Lancet commission report recognised the need for PPC. However, a variety of challenges have been identified to PPC development globally such as: access to treatment, access to medications such as oral morphine, opiophobia, a lack of trained health and social care professionals, a lack of PPC policies and a lack of awareness about PPC. These challenges can be overcome utilising a variety of strategies including advocacy and public awareness, education, access to medications, implementation and research. Examples will be discussed impacting on the provision of PPC in resource-poor settings. High-quality PPC service provision can be provided with resource-poor settings, and there is an urgent need to scale up affordable, accessible, and quality PPC services globally to ensure that all children needing palliative care can access it. PMID- 29463066 TI - OASL1 Traps Viral RNAs in Stress Granules to Promote Antiviral Responses. AB - Oligoadenylate synthetase (OAS) protein family is the major interferon (IFN) stimulated genes responsible for the activation of RNase L pathway upon viral infection. OAS-like (OASL) is also required for inhibition of viral growth in human cells, but the loss of one of its mouse homolog, OASL1, causes a severe defect in termination of type I interferon production. To further investigate the antiviral activity of OASL1, we examined its subcellular localization and regulatory roles in IFN production in the early and late stages of viral infection. We found OASL1, but not OASL2, formed stress granules trapping viral RNAs and promoted efficient RLR signaling in early stages of infection. Stress granule formation was dependent on RNA binding activity of OASL1. But in the late stages of infection, OASL1 interacted with IRF7 transcripts to inhibit translation resulting in down regulation of IFN production. These results implicate that OASL1 plays context dependent functions in the antiviral response for the clearance and resolution of viral infections. PMID- 29463067 TI - Liraglutide Inhibits the Apoptosis of MC3T3-E1 Cells Induced by Serum Deprivation through cAMP/PKA/beta-Catenin and PI3K/AKT/GSK3beta Signaling Pathways. AB - In recent years, the interest towards the relationship between incretins and bone has been increasing. Previous studies have suggested that glucagon-like peptide-1 (GLP-1) and its receptor agonists exert beneficial anabolic influence on skeletal metabolism, such as promoting proliferation and differentiation of osteoblasts via entero-osseous-axis. However, little is known regarding the effects of GLP-1 on osteoblast apoptosis and the underlying mechanisms involved. Thus, in the present study, we investigated the effects of liraglutide, a glucagon-like peptide-1 receptor agonist, on apoptosis of murine MC3T3-E1 osteoblastic cells. We confirmed the presence of GLP-1 receptor (GLP-1R) in MC3T3-E1 cells. Our data demonstrated that liraglutide inhibited the apoptosis of osteoblastic MC3T3-E1 cells induced by serum deprivation, as detected by Annexin V/PI and Hoechst 33258 staining and ELISA assays. Moreover, liraglutide upregulated Bcl-2 expression and downregulated Bax expression and caspase-3 activity at intermediate concentration (100 nM) for maximum effect. Further study suggested that liraglutide stimulated the phosphorylation of AKT and enhanced cAMP level, along with decreased phosphorylation of GSK3beta, increased beta-catenin phosphorylation at Ser675 site and upregulated nuclear beta-catenin content and transcriptional activity. Pretreatment of cells with the PI3K inhibitor LY294002, PKA inhibitor H89, and siRNAs GLP-1R, beta-catenin abrogated the liraglutide-induced activation of cAMP, AKT, beta-catenin, respectively. In conclusion, these findings illustrate that activation of GLP-1 receptor by liraglutide inhibits the apoptosis of osteoblastic MC3T3-E1 cells induced by serum deprivation through cAMP/PKA/beta catenin and PI3K/Akt/GSK3beta signaling pathways. PMID- 29463063 TI - The Yeast Saccharomyces cerevisiae as a Model for Understanding RAS Proteins and their Role in Human Tumorigenesis. AB - The exploitation of the yeast Saccharomyces cerevisiae as a biological model for the investigation of complex molecular processes conserved in multicellular organisms, such as humans, has allowed fundamental biological discoveries. When comparing yeast and human proteins, it is clear that both amino acid sequences and protein functions are often very well conserved. One example of the high degree of conservation between human and yeast proteins is highlighted by the members of the RAS family. Indeed, the study of the signaling pathways regulated by RAS in yeast cells led to the discovery of properties that were often found interchangeable with RAS proto-oncogenes in human pathways, and vice versa. In this work, we performed an updated critical literature review on human and yeast RAS pathways, specifically highlighting the similarities and differences between them. Moreover, we emphasized the contribution of studying yeast RAS pathways for the understanding of human RAS and how this model organism can contribute to unveil the roles of RAS oncoproteins in the regulation of mechanisms important in the tumorigenic process, like autophagy. PMID- 29463068 TI - Benzidine Induces Epithelial-Mesenchymal Transition of Human Bladder Cancer Cells through Activation of ERK5 Pathway. AB - Benzidine, a known carcinogen, is closely associated with the development of bladder cancer (BC). Epithelial-mesenchymal transition (EMT) is a critical pathophysiological process in BC progression. The underlying molecular mechanisms of mitogen-activated protein kinase (MAPK) pathway, especially extracellular regulated protein kinases 5 (ERK5), in regulating benzidine-induced EMT remains unclarified. Hence, two human bladder cell lines, T24 and EJ, were utilized in our study. Briefly, cell migration was assessed by wound healing assay, and cell invasion was determined by Transwell assay. Quantitative PCR and western blot were utilized to determine both gene expressions as well as protein levels of EMT and MAPK, respectively. Small interfering RNA (siRNA) was transfected to further determine ERK5 function. As a result, the migration and invasion abilities were enhanced, epithelial marker expression was decreased while mesenchymal marker expression was increased in human BC cell lines. Meanwhile, benzidine administration led to activation of ERK5 and activator protein 1 (AP-1) proteins, without effective stimulation of the Jun N-terminal kinase (JNK) or p38 pathways. Moreover, Benzidine-induced EMT and ERK5 activation were completely suppressed by XMD8-92 and siRNAs specific to ERK5. Of note, ERK1/2 was activated in benzidine treated T24 cells, while benzidine-induced EMT could not be reversed by U0126, an ERK1/2 inhibitor, as indicated by further study. Collectively, our findings revealed that ERK5-mediated EMT was critically involved in benzidine-correlated BC progression, indicating the therapeutic significance of ERK5 in benzidine related BC. PMID- 29463069 TI - Regulation of Ethylene Biosynthesis by Phytohormones in Etiolated Rice (Oryza sativa L.) Seedlings. AB - The gaseous hormone ethylene influences many aspects of plant growth, development, and responses to a variety of stresses. The biosynthesis of ethylene is tightly regulated by various internal and external stimuli, and the primary target of the regulation is the enzyme 1-aminocyclopropane-1-carboxylic acid (ACC) synthase (ACS), which catalyzes the rate-limiting step of ethylene biosynthesis. We have previously demonstrated that the regulation of ethylene biosynthesis is a common feature of most of the phytohormones in etiolated Arabidopsis seedlings via the modulation of the protein stability of ACS. Here, we show that various phytohormones also regulate ethylene biosynthesis from etiolated rice seedlings in a similar manner to those in Arabidopsis. Cytokinin, brassinosteroids, and gibberellic acid increase ethylene biosynthesis without changing the transcript levels of neither OsACS nor ACC oxidases (OsACO), a family of enzymes catalyzing the final step of the ethylene biosynthetic pathway. Likewise, salicylic acid and abscisic acid do not alter the gene expression of OsACS, but both hormones downregulate the transcript levels of a subset of ACO genes, resulting in a decrease in ethylene biosynthesis. In addition, we show that the treatment of the phytohormones results in distinct etiolated seedling phenotypes, some of which resemble ethylene-responsive phenotypes, while others display ethylene-independent morphologies, indicating a complicated hormone crosstalk in rice. Together, our study brings a new insight into crosstalk between ethylene biosynthesis and other phytohormones, and provides evidence that rice ethylene biosynthesis could be regulated by the post-transcriptional regulation of ACS proteins. PMID- 29463071 TI - Hypoxia Upregulates Mitotic Cyclins Which Contribute to the Multipotency of Human Mesenchymal Stem Cells by Expanding Proliferation Lifespan. AB - Hypoxic culture is widely recognized as a method to efficiently expand human mesenchymal stem cells (MSCs) without loss of stem cell properties. However, the molecular basis of how hypoxia priming benefits MSC expansion remains unclear. In this report, our systemic quantitative proteomic and RT-PCR analyses revealed the involvement of hypoxic conditioning activated genes in the signaling process of the mitotic cell cycle. Introduction of screened two mitotic cyclins, CCNA2 and CCNB1, significantly extended the proliferation lifespan of MSCs in normoxic condition. Our results provide important molecular evidence that multipotency of human MSCs by hypoxic conditioning is determined by the mitotic cell cycle duration. Thus, the activation of mitotic cyclins could be a potential strategy to the application of stem cell therapy. PMID- 29463070 TI - Cigarette Smoke Extract Enhances IL-17A-Induced IL-8 Production via Up-Regulation of IL-17R in Human Bronchial Epithelial Cells. AB - Interleukin-17A (IL-17A) is a pro-inflammatory cytokine mainly derived from T helper 17 cells and is known to be involved in the pathogenesis of chronic obstructive pulmonary disease (COPD). Cigarette smoke (CS) has been considered as a primary risk factor of COPD. However, the interaction between CS and IL-17A and the underlying molecular mechanisms have not been clarified. In the current study, we investigated the effects of cigarette smoke extract (CSE) on IL-17A induced IL-8 production in human bronchial epithelial cells, and sought to identify the underlying molecular mechanisms. IL-8 production was significantly enhanced following treatment with both IL-17A and CSE, while treatment with either IL-17A or CSE alone caused only a slight increase in IL-8 production. CSE increased the transcription of IL-17RA/RC and surface membrane expression of IL 17R, which was suppressed by an inhibitor of the phosphoinositide 3-kinase (PI3K)/Akt pathway (LY294002). CSE caused inactivation of glycogen synthase kinase-3beta (GSK-3beta) via the PI3K/Akt pathway. Blockade of GSK-3beta inactivation by overexpression of constitutively active GSK-3beta (S9A) completely suppressed the CSE-induced up-regulation of IL-17R expression and the CSE-induced enhancement of IL-8 secretion. In conclusion, inactivation of GSK 3beta via the PI3K/Akt pathway mediates CSE-induced up-regulation of IL-17R, which contributes to the enhancement of IL-17A-induced IL-8 production. PMID- 29463072 TI - The Effects of Donepezil, an Acetylcholinesterase Inhibitor, on Impaired Learning and Memory in Rodents. AB - A previous study in humans demonstrated the sustained inhibitory effects of donepezil on acetylcholinesterase (AChE) activity; however, the effective concentration of donepezil in humans and animals is unclear. This study aimed to characterize the effective concentration of donepezil on AChE inhibition and impaired learning and memory in rodents. A pharmacokinetic study of donepezil showed a mean peak plasma concentration of donepezil after oral treatment (3 and 10 mg/kg) of approximately 1.2 +/- 0.4 h and 1.4 +/- 0.5 h, respectively; absolute bioavailability was calculated as 3.6%. Further, AChE activity was inhibited by increasing plasma concentrations of donepezil, and a maximum inhibition of 31.5 +/- 5.7% was observed after donepezil treatment in hairless rats. Plasma AChE activity was negatively correlated with plasma donepezil concentration. The pharmacological effects of donepezil are dependent upon its concentration and AChE activity; therefore, we assessed the effects of donepezil on learning and memory using a Y-maze in mice. Donepezil treatment (3 mg/kg) significantly prevented the progression of scopolamine-induced memory impairment in mice. As the concentration of donepezil in the brain increased, the recovery of spontaneous alternations also improved; maximal improvement was observed at 46.5 +/- 3.5 ng/g in the brain. In conclusion, our findings suggest that the AChE inhibitory activity and pharmacological effects of donepezil can be predicted by the concentration of donepezil. Further, 46.5 +/- 3.5 ng/g donepezil is an efficacious target concentration in the brain for treating learning and memory impairment in rodents. PMID- 29463074 TI - Diabetes insipidus in pregnancy: how to advice the patient? AB - Diabetes insipidus, characterized by polyuria and polydipsia, is a rare disease during pregnancy. Nevertheless, its recognition is important to avoid complications due to dehydration and hypernatremia. Its manifestation during pregnancy ranges from exacerbation of pre-existing central or nephrogenic diabetes insipidus to transient pregnancy-induced diabetes insipidus due to the increased metabolism of the antidiuretic hormone vasopressin (AVP) by the placental vasopressinase. Diagnosis can be challenging, as urinary frequency is common during pregnancy and primary polydipsia also needs to be excluded. Also, the standard water deprivation test is not recommended during pregnancy due to the increased risk of complications. Treatment depends upon the final diagnosis, with desmopressin (DDAVP) being the medication of choice in AVP-deficient diabetes insipidus, whereas nephrogenic diabetes insipidus requires treatment of the underlying disease and supportive measures. PMID- 29463073 TI - T-Type Calcium Channels Are Required to Maintain Viability of Neural Progenitor Cells. AB - T-type calcium channels are low voltage-activated calcium channels that evoke small and transient calcium currents. Recently, T-type calcium channels have been implicated in neurodevelopmental disorders such as autism spectrum disorder and neural tube defects. However, their function during embryonic development is largely unknown. Here, we investigated the function and expression of T-type calcium channels in embryonic neural progenitor cells (NPCs). First, we compared the expression of T-type calcium channel subtypes (CaV3.1, 3.2, and 3.3) in NPCs and differentiated neural cells (neurons and astrocytes). We detected all subtypes in neurons but not in astrocytes. In NPCs, CaV3.1 was the dominant subtype, whereas CaV3.2 was weakly expressed, and CaV3.3 was not detected. Next, we determined CaV3.1 expression levels in the cortex during early brain development. Expression levels of CaV3.1 in the embryonic period were transiently decreased during the perinatal period and increased at postnatal day 11. We then pharmacologically blocked T-type calcium channels to determine the effects in neuronal cells. The blockade of T-type calcium channels reduced cell viability, and induced apoptotic cell death in NPCs but not in differentiated astrocytes. Furthermore, blocking T-type calcium channels rapidly reduced AKT-phosphorylation (Ser473) and GSK3beta-phosphorylation (Ser9). Our results suggest that T-type calcium channels play essential roles in maintaining NPC viability, and T-type calcium channel blockers are toxic to embryonic neural cells, and may potentially be responsible for neurodevelopmental disorders. PMID- 29463075 TI - Adverse effects of doping with anabolic androgenic steroids in competitive athletics, recreational sports and bodybuilding. AB - Despite the fact that sports organizations and legislators have introduced various mechanisms to discourage athletes from using performance and appearance enhancing substances a high percentage of athletes admits to their unabated application. In competitive athletics, bodybuilding and in recreational sports anabolic androgenic steroids (AAS) continue to be the substances most abused. This review summarizes the side effects of AAS abuse on organs and system functions in both sexes. High doses of AAS cause a significant increase of erythrocytes and hemoglobin concentration, which may lead to thromboembolism, intracardiac thrombosis and stroke. Long-term AAS abusers have a higher incidence of arrhythmias, atherosclerosis, concentric left-ventricular myocardial hypertrophy with impaired diastolic function and also sudden cardiac death. Changes of liver function and structure, up to hepatocellular carcinoma, have been described, mainly in cases of chronic misuse of 17alpha-alkylated AAS. Sleeplessness, increased irritability, depressive mood status are often observed in AAS abuse. In former AAS abusers depression, anxiety and melancholy may persist for many years. Due to negative feedback in the regulation of the hypothalamic-pituitary-gonadal axis AAS can cause reversible suppression of spermatogenesis up to azoospermia. In women the changes most often caused by AAS abuse are hirsutism, irreversible deepening of voice, dysmenorrhea, secondary amenorrhea with anovulation and infertility. AAS abuse notwithstanding, under clinical conditions testosterone remains the most important hormone for substitution therapy of male hypogonadism. PMID- 29463076 TI - Acute pituitary disease in pregnancy: how to handle hypophysitis and Sheehan's syndrome. AB - Pregnancy-related hypophysitis (PR-Hy) that typically occurs during late pregnancy and the early postpartum period is considered an autoimmune disorder. Knowledge and awareness of characteristic clinical symptoms and specific endocrine and neuroradiological features mostly enables a correct diagnosis and guarantees best possible management. In the presence of mild clinical symptoms, a "wait-and-watch" approach is recommended. Transsphenoidal surgery or glucocorticoid therapy is indicated if progressive clinical signs or severe visual symptoms are observed. Reported cases indicate that transsphenoidal surgery performed during pregnancy can reverse visual symptoms and has a minimal risk to the health of the fetus and mother. Glucocorticoid therapy has a high initial response rate, but recurrence can occur after discontinuation. In late pregnancy hypophysitis, the options of delaying therapy until the child is born or, if symptoms are severe, of inducing delivery prior to therapy have to be considered. Sheehan's syndrome (SS) is characterized by irreversible, partial or complete hypopituitarism due to pituitary infarction. The predominating causative event is massive peripartum hemorrhage (PPH). A considerable diagnostic delay is mostly observed. PPH and the typical postpartum findings of agalactia and amenorrhea should alert for the diagnosis of SS and prompt endocrine evaluation. Timely hormone replacement therapy is paramount to reduce morbidity and mortality and improve quality of life of afflicted women. Adrenal failure is a major endocrinological risk both of hypophysitis and of Sheehan syndrome. Early recognition and treatment is paramount to avoid life-threatening adrenal crisis.

AB - INTRODUCTION: Endovascular approach to abdominal aortic aneurysm has increased in frequency over the last decade and is preferred by many practitioners and patients alike. However, its role in "complex" aneurysms with challenging anatomy, short neck length, or borderline landing zone for grafts is less well understood. Additionally, the endovascular role in complex urgent or emergent repairs has not been adequately studied. Several techniques have been developed in order to address these concerns and further the endovascular approach. This article seeks to describe incidents in which an endovascular approach may be challenging, describe the most popular techniques now available for approaching these cases, and present the best literature available for considering these techniques. EVIDENCE ACQUISITION: Medline searches were performed with the key words "complex endovascular aneurysm repair," "fenestrated endovascular aneurysm repair," "chimney grafts" and "snorkel grafts" to gain access to available data. EVIDENCE SYNTHESIS: Articles were reviewed for results and technical considerations. CONCLUSIONS: By employing increasingly complex endovascular techniques, complex pararenal aneurysms can be successfully treated in an endovascular fashion. PMID- 29463079 TI - Prevention of venous thromboembolism through the implementation of a risk assessment tool: a comparative study in medical and surgical patients. AB - BACKGROUND: Hospitalized patients are at high risk of venous thromboembolism (VTE). Underutilization of thromboprophylaxis remains common despite existing clinical guidelines. The aim is to evaluate the implementation of a state wide standardized adult VTE risk assessment tool (RAT) to assist in the screening of inpatients and prescribing of appropriate thromboprophylaxis. METHODS: In total, 234 patients were audited using clinical notes and spot assessments for VTE risk at Western Sydney Local Health District over a two year period. Patients were stratified into pre- (N.=132) and postimplementation (N.=102) of the RAT. Intervention involved continuing education of staff and passive dissemination of guidelines. Prescription of pharmacological and mechanical prophylaxis and the development of thromboembolic events were evaluated. RESULTS: Overall, 39.0% of medical and 63.0% of surgical patients were risk assessed during preimplementation versus 39.2% and 92.2% during postimplementation of the RAT (P<0.0001). Usage of pharmacological prophylaxis increased from 72% to 79% and mechanical prophylaxis from 41% to 48%. VTE rates in moderate to high risk medical patients decreased from 15.2% preimplementation to 6.5% postimplementation. Rates of non-fatal and fatal pulmonary embolism (PE) were 2.3% and 0.8% respectively prior compared to 1.0% and 0.0% postimplementation. CONCLUSIONS: Standardized VTE RAT increased thromboprophylaxis usage and decreased PE rates, with a greater improvement reflected in surgical patients. These findings highlight the importance of a multifaceted approach to VTE prevention using regular audits with feedback, electronic reminders systems, prescribing tools and continuing education.

AB - Understanding the rheological properties of two-dimensional (2D) materials in suspension is critical for the development of various solution processing and manufacturing techniques. 2D carbides and nitrides (MXenes) constitute one of the largest families of 2D materials with >20 synthesized compositions and applications already ranging from energy storage to medicine to optoelectronics. However, in spite of a report on clay-like behavior, not much is known about their rheological response. In this study, rheological behavior of single- and multilayer Ti3C2T x in aqueous dispersions was investigated. Viscous and viscoelastic properties of MXene dispersions were studied over a variety of concentrations from colloidal dispersions to high loading slurries, showing that a multilayer MXene suspension with up to 70 wt % can exhibit flowability. Processing guidelines for the fabrication of MXene films, coatings, and fibers have been established based on the rheological properties. Surprisingly, high viscosity was observed at very low concentrations for solutions of single-layer MXene flakes. Single-layer colloidal solutions were found to exhibit partial elasticity even at the lowest tested concentrations (<0.20 mg/mL) due to the presence of strong surface charge and excellent hydrophilicity of MXene, making them amenable to fabrication at dilute concentrations. Overall, the findings of this study provide fundamental insights into the rheological response of this quickly growing 2D family of materials in aqueous environments as well as offer guidelines for processing of MXenes.

AB - Copper chalcogenide nanoparticles (Cu2S) synthesized for the first time from a single-source precursor, CuSPh, act as highly efficient and reusable heterogeneous catalyst for regioselective amination of N, N-dimethylbenzylamines with various azoles. The reaction involves N-H/C-H cross-dehydrogenative coupling (CDC) and demonstrates wide functional group tolerance. It provides highly selective access to N1-alkylated benzotriazoles, N2-alkylated 1,2,3-triazoles and 4-phenyl-1,2,3-triazoles, and N-alkylated carbazoles in 70-89% yields under solvent-free conditions. The Cu2S nanocatalyst has been characterized by PXRD, XPS, SEM-EDX, and HR-TEM analysis. Mechanistic studies suggest that the reaction follows a radical pathway and involves an iminium ion intermediate.

AB - Molecular changes in dissolved organic matter (DOM) from treatment processes at two drinking water treatment plants in Japan were investigated using unknown screening analysis by Orbitrap mass spectrometry. DOM formulas with carbon, hydrogen and oxygen (CHO-DOM) were the most abundant class in water samples, and over half of them were commonly found at both plants. Among the treatment processes, ozonation induced the most drastic changes to DOM. Mass peak intensities of less saturated CHO-DOM (positive (oxygen subtracted double bond equivalent per carbon (DBE-O)/C)) decreased by ozonation, while more saturated oxidation byproducts (negative (DBE-O)/C) increased and new oxidation byproducts (OBPs) were detected. By Kendrick mass analysis, ozone reactions preferred less saturated CHO-DOM in the same alkylation families and produced more saturated alkylation families of OBPs. Following ozonation, biological activated carbon filtration effectively removed <300 Da CHO-DOM, including OBPs. Following chlorination, over 50 chlorinated formulas of disinfection byproducts (DBPs) were found in chlorinated water samples where at least half were unknown. Putative precursors of these DBPs were determined based on electrophilic substitutions and addition reactions. Ozonation demonstrated better decomposition of addition reaction-type precursors than electrophilic substitution-type precursors; over half of both precursor types decreased during biological activated carbon filtration.

AB - Drying graphene oxide (GO) films are subject to extensive wrinkling, which largely affects their final properties. Wrinkles were shown to be suitable in biotechnological applications; however, they negatively affect the electronic properties of the films. Here, we report on wrinkle tuning and patterning of GO films under stress-controlled conditions during drying. GO flakes assemble at an air-solvent interface; the assembly forms a skin at the surface and may bend due to volume shrinkage while drying. We applied a modification of evaporative lithography to spatially define the evaporative stress field. Wrinkle alignment is achieved over cm2 areas. The wavelength (i.e., wrinkle spacing) is controlled in the MUm range by the film thickness and GO concentration. Furthermore, we propose the use of nanoparticles to control capillary forces to suppress wrinkling. An example of a controlled pattern is given to elucidate the potential of the technique. The results are discussed in terms of classical elasticity theory. Wrinkling is the result of bending of the wet solid skin layer assembled on a highly elastic GO dispersion. Wavelength selection is the result of energy minimization between the bending of the skin and the elastic deformation of the GO supporting dispersion. The results strongly suggest the possibility to tune wrinkles and patterns by simple physicochemical routes.

AB - The clinical applications of positron emission tomography (PET) imaging pharmaceuticals have increased tremendously over the past several years since the approval of 18fluorine-fluorodeoxyglucose (18F-FDG) by the Food and Drug Administration (FDA). Numerous 18F-labeled target-specific potential imaging pharmaceuticals, based on small and large molecules, have been evaluated in preclinical and clinical settings. 18F-labeling of organic moieties involves the introduction of the radioisotope by C-18F bond formation via a nucleophilic or an electrophilic substitution reaction. However, biomolecules, such as peptides, proteins, and oligonucleotides, cannot be radiolabeled via a C-18F bond formation as these reactions involve harsh conditions, including organic solvents, high temperature, and nonphysiological conditions. Several approaches, including 18F labeled prosthetic groups, silicon, boron, and aluminum fluoride acceptor chemistry, and click chemistry have been developed, in the past, for 18F labeling of biomolecules. Linear and macrocyclic polyaminocarboxylates and their analogs and derivatives form thermodynamically stable and kinetically inert aluminum chelates. Hence, macrocyclic polyaminocarboxylates have been used for conjugation with biomolecules, such as folate, peptides, affibodies, and protein fragments, followed by 18F-AlF chelation, and evaluation of their targeting abilities in preclinical and clinical environments. The goal of this report is to provide an overview of the 18F radiochemistry and 18F-labeling methodologies for small molecules and target-specific biomolecules, a comprehensive review of coordination chemistry of Al3+, 18F-AlF labeling of peptide and protein conjugates, and evaluation of 18F-labeled biomolecule conjugates as potential imaging pharmaceuticals. PMID- 29463085 TI - Spectroscopic and DFT Characterization of a Highly Reactive Nonheme FeV-Oxo Intermediate. AB - The reaction of [(PyNMe3)FeII(CF3SO3)2], 1, with excess peracetic acid at -40 degrees C generates a highly reactive intermediate, 2b(PAA), that has the fastest rate to date for oxidizing cyclohexane by a nonheme iron species. It exhibits an intense 490 nm chromophore associated with an S = 1/2 EPR signal having g-values at 2.07, 2.01, and 1.94. This species was shown to be in a fast equilibrium with a second S = 1/2 species, 2a(PAA), assigned to a low-spin acylperoxoiron(III) center. Unfortunately, contaminants accompanying the 2(PAA) samples prevented determination of the iron oxidation state by Mossbauer spectroscopy. Use of MeO PyNMe3 (an electron-enriched version of PyNMe3) and cyclohexyl peroxycarboxylic acid as oxidant affords intermediate 3b(CPCA) with a Mossbauer isomer shift delta = -0.08 mm/s that indicates an iron(V) oxidation state. Analysis of the Mossbauer and EPR spectra, combined with DFT studies, demonstrates that the electronic ground state of 3b(CPCA) is best described as a quantum mechanical mixture of [(MeO-PyNMe3)FeV(O)(OC(O)R)]2+ (~75%) with some FeIV(O)(*OC(O)R) and FeIII(OOC(O)R) character. DFT studies of 3b(CPCA) reveal that the unbound oxygen of the carboxylate ligand, O2, is only 2.04 A away from the oxo group, O1, corresponding to a Wiberg bond order for the O1-O2 bond of 0.35. This unusual geometry facilitates reversible O1-O2 bond formation and cleavage and accounts for the high reactivity of the intermediate when compared to the rates of hydrogen atom transfer and oxygen atom transfer reactions of FeIII(OC(O)R) ferric acyl peroxides and FeIV(O) complexes. The interaction of O2 with O1 leads to a significant downshift of the Fe-O1 Raman frequency (815 cm-1) relative to the 903 cm-1 value predicted for the hypothetical [(MeO-PyNMe3)FeV(O)(NCMe)]3+ complex. PMID- 29463086 TI - Highly Active NiO Photocathodes for H2O2 Production Enabled via Outer-Sphere Electron Transfer. AB - Tandem dye-sensitized photoelectrosynthesis cells are promising architectures for the production of solar fuels and commodity chemicals. A key bottleneck in the development of these architectures is the low efficiency of the photocathodes, leading to small current densities. Herein, we report a new design principle for highly active photocathodes that relies on the outer-sphere reduction of a substrate from the dye, generating an unstable radical that proceeds to the desired product. We show that the direct reduction of dioxygen from dye sensitized nickel oxide (NiO) leads to the production of H2O2. In the presence of oxygen and visible light, NiO photocathodes sensitized with commercially available porphyrin, coumarin, and ruthenium dyes exhibit large photocurrents (up to 400 MUA/cm2) near the thermodynamic potential for O2/H2O2 in near-neutral water. Bulk photoelectrolysis of porphyrin-sensitized NiO over 24 h results in millimolar concentrations of H2O2 with essentially 100% faradaic efficiency. To our knowledge, these are among the most active NiO photocathodes reported for multiproton/multielectron transformations. The photoelectrosynthesis proceeds by initial formation of superoxide, which disproportionates to H2O2. This disproportionation-driven charge separation circumvents the inherent challenges in separating electron-hole pairs for photocathodes tethered to inner sphere electrocatalysts and enables new applications for photoelectrosynthesis cells.

AB - Post traumatic stress disorder (PTSD) may first emerge, reemerge, or worsen as individuals approach end of life and may complicate the dying process. Unfortunately, lack of awareness of the occurrence and/or manifestation of PTSD at end of life can lead to PTSD going unaddressed. Even if PTSD is properly diagnosed, traditional evidence-based trauma-focused treatments may not be feasible or advisable with this group as many patients at end of life often lack the physical and mental stamina to participate in traditional psychotherapy. This article reviews the clinical and empirical literature on PTSD at end of life, as well as discusses assessment and psychotherapy treatment issues with this neglected population. In addition, it expands on the current reviews of this literature1-3 by extrapolating results from nontraditional treatment approaches with other patient populations. Elements of these approaches with patients sharing similar characteristics and/or comorbidities with patients with PTSD at end of life may provide additional benefits for the latter population. Clinical implications and suggestions for interdisciplinary care providers are provided. PMID- 29463091 TI - Urinary Tract Infections: Pilot Study to Improve Guideline Adherence. PMID- 29463092 TI - Super-Utilization of Health Care Resources Among Gynecologic Oncology Patients. AB - Super-utilizers account for many emergency department visits (EDV) and hospitalizations. Among Medicare/Medicaid patients, 5% to 10% account for >50% of spending. Little is known about super-utilization in gynecologic oncology. Charts of 64 gynecologic oncology patients with >=3 EDV and/or admissions over 12 months were reviewed retrospectively. Cancer type distribution was 47% ovarian, 23% cervical, 23% endometrial, and 6% vulvar. Treatment at index visit was 61% chemotherapy, 16% no treatment, 8% recent surgery, and 6% radiation. Mean visits was 5.7 (SD 3.9, range 3-28). Most common presenting complaints were gastrointestinal and pain. Patients near end of life were more likely to be admitted. EDV frequently occurred outside standard work hours (63%). EDV/admissions resulted in total variable expenses of $1 462 581 ($982 933 direct expense, $479 648 service expense). Interventions to decrease super-utilization could target symptom management, off-hour support, patients on chemotherapy, and end of life. Approaches could include multidisciplinary resources, palliative care teams, extending office hours, and earlier initiation of hospice. PMID- 29463093 TI - Utility of DWI with quantitative ADC values in ovarian tumors: a meta-analysis of diagnostic test performance. AB - Background Diffusion-weighted imaging (DWI) and quantitative apparent diffusion coefficient (ADC) values are widely used in the differential diagnosis of ovarian tumors. Purpose To assess the diagnostic performance of quantitative ADC values in ovarian tumors. Material and Methods PubMed, Embase, the Cochrane Library, and local databases were searched for studies assessing ovarian tumors using quantitative ADC values. We quantitatively analyzed the diagnostic performances for two clinical problems: benign vs. malignant tumors and borderline vs. malignant tumors. We evaluated diagnostic performances by the pooled sensitivity and specificity values and by summary receiver operating characteristic (SROC) curves. Subgroup analyses were used to analyze study heterogeneity. Results From the 742 studies identified in the search results, 16 studies met our inclusion criteria. A total of ten studies evaluated malignant vs. benign ovarian tumors and six studies assessed malignant vs. borderline ovarian tumors. Regarding the diagnostic accuracy of quantitative ADC values for distinguishing between malignant and benign ovarian tumors, the pooled sensitivity and specificity values were 0.91 and 0.91, respectively. The area under the SROC curve (AUC) was 0.96. For differentiating borderline from malignant tumors, the pooled sensitivity and specificity values were 0.89 and 0.79, and the AUC was 0.91. The methodological quality of the included studies was moderate. Conclusion Quantitative ADC values could serve as useful preoperative markers for predicting the nature of ovarian tumors. Nevertheless, prospective trials focused on standardized imaging parameters are needed to evaluate the clinical value of quantitative ADC values in ovarian tumors. PMID- 29463094 TI - Use of personal electronic devices by psychiatric inpatients: benefits, risks and attitudes of patients and staff. AB - OBJECTIVES: The study aimed to evaluate the attitudes of patients and staff in relation to the potential benefits and risks of allowing psychiatric inpatients controlled access to personal electronic devices (PEDs), and to document a snapshot audit of practice within the mental health inpatient units of New South Wales, Australia. METHODS: Psychiatric inpatients and staff at Royal North Shore Hospital's Mental Health inpatient units were surveyed, and an audit of the policies of the psychiatric inpatients of New South Wales was undertaken. RESULTS: Access to PEDs is denied in 85% of New South Wales psychiatric inpatient units. While patients and staff appear to concur on the risks of access to PEDs and the need for risk assessment and rules, compared to patients, staff appear to underestimate the importance of PEDs to maintaining social connection and recovery. CONCLUSIONS: This study may assist in the formulation of local policy and procedure to allow a more recovery-oriented approach to the question of whether patients should have access to their PEDs while in hospital.

AB - This review describes the current state of discovery of past most important nucleoside and nucleotide prodrugs in the treatment of hepatitis C virus infection as well as future potential drugs currently in discovery or clinical evaluation. I highlight first generation landmark prodrug compounds which have been the foundations of incremental improvements toward the discovery and approval milestone of Sofosbuvir. Sofosbuvir is the first nucleotide prodrug marketed for hepatitis C virus treatment and the backbone of current combination therapies. Since this approval, new nucleotide prodrugs using the same design of Sofosbuvir McGuigan prodrug have emerged, some of them progressing through advanced clinical trials and may become available as new incremental alternative hepatitis C virus treatments in the future. Although since Sofosbuvir success, only minimal design efforts have been invested in finding better liver targeted prodrugs, a few novel prodrugs are being studied and their different modes of activation may prove beneficial over the heart/liver targeting ratio to reduce potential drug-drug interaction in combination therapies and yield safer treatment to patients. Prodrugs have long been avoided as much as possible in the past by development teams due to their metabolism and kinetic characterization complexity, but with their current success in hepatitis C virus treatment, and the knowledge gained in this endeavor, should become a first choice in future tissue targeting drug discovery programs beyond the particular case of nucleos(t)ide analogs. PMID- 29463096 TI - Inhibition of Radiation-Induced Ccl2 Signaling Protects Lungs from Vascular Dysfunction and Endothelial Cell Loss. AB - AIMS: Radiation-induced normal tissue toxicity often precludes the application of curative radiation doses. Here we investigated the therapeutic potential of chemokine C-C motif ligand 2 (Ccl2) signaling inhibition to protect normal lung tissue from radiotherapy (RT)-induced injury. RESULTS: RT-induced vascular dysfunction and associated adverse effects can be efficiently antagonized by inhibition of Ccl2 signaling using either the selective Ccl2 inhibitor bindarit (BIN) or mice deficient for the main Ccl2 receptor CCR2 (KO). BIN-treatment efficiently counteracted the RT-induced expression of Ccl2, normalized endothelial cell (EC) morphology and vascular function, and limited lung inflammation and metastasis early after irradiation (acute effects). A similar protection of the vascular compartment was detected by loss of Ccl2 signaling in lungs of CCR2-KO mice. Long-term Ccl2 signaling inhibition also significantly limited EC loss and accompanied fibrosis progression as adverse late effect. With respect to the human situation, we further confirmed that Ccl2 secreted by RT induced senescent epithelial cells resulted in the activation of normally quiescent but DNA-damaged EC finally leading to EC loss in ex vivo cultured human normal lung tissue. INNOVATION: Abrogation of certain aspects of the secretome of irradiated resident lung cells, in particular signaling inhibition of the senescence-associated secretory phenotype-factor Ccl2 secreted predominantly by RT-induced senescent epithelial cells, resulted in protection of the endothelial compartment. CONCLUSIONS: Radioprotection of the normal tissue via Ccl2 signaling inhibition without simultaneous protection or preferable radiosensitization of tumor tissue might improve local tumor control and survival, because higher doses of radiation could be used.

AB - Background and aims Internet gaming disorder (IGD) has been mainly studied among adolescents, and no research to date has examined its prevalence in general Chinese adult populations. This study estimated the prevalence of probable IGD in community-dwelling adults in Macao, China. Associations between IGD and psychological distress (i.e., depression and anxiety) as well as IGD and character strength (i.e., psychological resilience and purpose in life) were also tested. Methods A random, representative sample of 1,000 Chinese residents (44% males; mean age = 40.0) was surveyed using a telephone poll design from October to November 2016. Results The estimated prevalence of probable IGD was 2.0% of the overall sample and 4.3% among the recent gamers (n = 473), with no statistically significant sex and age effects observed (p > .05). The two most prevalent IGD symptoms were mood modification and continued engagement, despite negative consequences. Probable IGD respondents were more vulnerable to psychological distress (25.0% and 45.0% for moderate or above levels of depression and anxiety, respectively) than their non-IGD counterparts. They also reported a lower level of psychological resilience than non-IGD respondents. No significant buffering effect of the two character strength variables on the distress-IGD relationship was found. Discussion and conclusions These results provide empirical evidence that IGD is a mental health threat not only to adolescents but also to adults. IGD was significantly associated with psychological distress, which should be addressed in conjunction with IGD symptoms in interventions. Inclusion of gamers of both sexes and different age groups in future prevention programs is also recommended. PMID- 29463099 TI - Factors associated with uptake of home-based HIV counselling and testing and HIV care services among identified HIV-positive persons in Masaka, Uganda. AB - We investigated uptake of home-based HIV counselling and testing (HBHCT) and HIV care services post-HBHCT in order to inform the design of future HBHCT programmes. We used data from an open-label cluster-randomised controlled trial which had demonstrated the effectiveness of a post-HBHCT counselling intervention in increasing linkage to HIV care. HBHCT was offered to adults (>=18 years) from 28 rural communities in Masaka, Uganda; consenting HIV-positive care naive individuals were enrolled and referred for care. The trial's primary outcome was linkage to HIV care (clinic-verified registration for care) six months post HBHCT. Random effects logistic regression was used to investigate factors associated with HBHCT uptake, linkage to care, CD4 count receipt, and antiretroviral therapy (ART) initiation; all analyses of uptake of post-HBHCT services were adjusted for trial arm allocation. Of 13,455 adults offered HBHCT, 12,100 (89.9%) accepted. HBHCT uptake was higher among men [adjusted odds ratio (aOR) 1.20, 95% confidence interval (CI) = 1.07-1.36] than women, and decreased with increasing age. Of 551 (4.6%) persons who tested HIV-positive, 205 (37.2%) were in care. Of those not in care, 302 (87.3%) were enrolled in the trial and of these, 42.1% linked to care, 35.4% received CD4 counts, and 29.8% initiated ART at 6 months post-HBHCT. None of the investigated factors was associated with linkage to care. CD4 count receipt was lower in individuals who lived >=30 min from an HIV clinic (aOR 0.60, 95%CI = 0.34-1.06) versus those who lived closer. ART initiation was higher in older individuals (>=45 years versus <25 years, aOR 2.14, 95% CI = 0.98-4.65), and lower in single (aOR 0.60, 95% CI = 0.28-1.31) or divorced/separated/widowed (aOR 0.47, 95% CI = 0.23-0.93) individuals versus those married/cohabiting. HBHCT was highly acceptable but uptake of post-HBHCT care was low. Other than post-HBHCT counselling, this study did not identify specific issues that require addressing to further improve linkage to care. PMID- 29463098 TI - Both active and sham low-frequency rTMS single sessions over the right DLPFC decrease cue-induced cravings among pathological gamblers seeking treatment: A randomized, double-blind, sham-controlled crossover trial. AB - Background Craving is a core symptom of addictive disorders, such as pathological gambling for example. Over the last decade, several studies have assessed the efficacy of repetitive transcranial magnetic stimulation (rTMS) in the addiction field, which triggers the dorsolateral prefrontal cortex (DLPFC) to decrease craving. The STIMJEU study investigated whether a single session of low-frequency (LF, i.e., 1 Hz) rTMS applied to the right DLPFC reduced cue-induced gambling craving in a sample of treatment-seeking pathological gamblers. Methods Thirty patients received both active and sham rTMS in random order and were blinded to the condition in a within-subject crossover design. Outcome measures included self-reported gambling craving (Visual Analog Scale and Gambling Craving Scale) and physiological measures (heart rate and blood pressure). Results The rTMS sessions were associated with a significant decrease in the gambling urge, regardless of whether the session was active or sham. When controlling cue induced craving levels, no effects were observed on craving for active rTMS. Overall, rTMS was well-tolerated, and the credibility of the sham procedure was assessed and appeared to be appropriate. Conclusions We failed to demonstrate the specific efficacy of one session of LF rTMS to decrease cue-induced craving in pathological gamblers. A strong placebo-effect and rTMS parameters may partly explain these results. Yet, we are convinced that rTMS remains a promising therapeutic method. Further studies are required to examine its potential effect. PMID- 29463100 TI - Community treatment orders: towards a new research agenda. AB - OBJECTIVES: The aim of this study was to report on a half-day multi-stakeholder symposium on community treatment orders (CTOs) hosted by the Melbourne Social Equity Institute (MSEI), which identified research gaps and opportunities, and produced an agreed agenda for future CTO research. METHODS: The MSEI convened a symposium for 22 experts in CTO research to discuss research priorities in this field in Australasia. An independent moderator elicited views and recommendations and produced a report detailing possible research projects. RESULTS: Research on CTOs is contentious and there is a need to gather and examine information regarding both their use and utility. Due to the complexities involved, it was agreed that research should be undertaken in partnership with persons with had lived experience of mental health problems, clinicians, policymakers and other interdisciplinary stakeholders. Five key areas for future investigation were identified. CONCLUSIONS: The issues and recommendations arising from the symposium should shape the scope, nature and conduct of future research directions in the field. PMID- 29463102 TI - Social and behavioral factors associated with failing second-line ART - results from a cohort study at the Themba Lethu Clinic, Johannesburg, South Africa. AB - Poor adherence is a main challenge to successful second-line ART in South Africa. Studies have shown that patients can re-suppress their viral load following intensive adherence counselling. We identify factors associated with failure to re-suppress on second-line ART. The study was a retrospective cohort study which included HIV-positive adults who experienced an elevated viral load >=400 copies/ml on second-line ART between January 2013-July 2014, had completed an adherence counselling questionnaire and had a repeat viral load result recorded within 6 months of intensive adherence counselling. Log-binomial regression was used to evaluate the association between patient characteristics and social, behavioral or occupational factors and failure to suppress viral load (>=400 copies/ml). A total of 128 patients were included in the analysis, and of these 39% (n = 50) failed to re-suppress their viral load. Compared to those who suppressed, far more patients who failed to suppress reported living with family (44.2% vs. 23.7%), missing a dose in the past week (53.3% vs. 30.0%), using traditional/herbal medications (63.2% vs. 34.3%) or had symptoms suggestive of depression (57.7% vs. 34.3%). These patient-related factors could be targeted for interventions to reduce the risk for treatment failure and prevent switching to expensive third-line ART. PMID- 29463103 TI - Toward an Integrated Understanding of Retrograde Control of Photosynthesis. AB - SIGNIFICANCE: Photosynthesis takes place in the chloroplast of eukaryotes, which occupies a large portion of the photosynthetic cell. The chloroplast function and integrity depend on intensive material and signal exchange between all genetic compartments and conditionally secure efficient photosynthesis and high fitness. Recent Advances: During the last two decades, the concept of mutual control of plastid performance by extraplastidic anterograde signals acting on the chloroplast and the feedback from the chloroplast to the extraplastidic space by retrograde signals has been profoundly revised and expanded. It has become clear that a complex set of diverse signals is released from the chloroplast and exceeds the historically proposed small number of information signals. Thus, it is also recognized that redox compounds and reactive oxygen species play a decisive role in retrograde signaling. CRITICAL ISSUES: The diversity of processes controlled or modulated by the retrograde network covers all molecular levels, including RNA fate and translation, and also includes subcellular heterogeneity, indirect gating of other organelles' metabolism, and specific signaling routes and pathways, previously not considered. All these processes must be integrated for optimal adjustment of the chloroplast processes. Thus, evidence is presented suggesting that retrograde signaling affects translation, stress granule, and processing body (P-body) dynamics. FUTURE DIRECTIONS: Redundancy of signal transduction elements, parallelisms of pathways, and conditionally alternative mechanisms generate a robust network and system that only tentatively can be assessed by use of single-site mutants.

AB - Momordica charantia known as bitter melon is a representative medicinal plant reported to exhibit numerous pharmacological activities such as antibacterial, antidiabetic, anti-inflammatory, anti-oxidant, antitumor, and hypoglycemic actions. Although this plant has high ethnopharmacological value for treating inflammatory diseases, the molecular mechanisms by which it inhibits the inflammatory response are not fully understood. In this study, we aim to identify the anti-inflammatory mechanism of this plant. To this end, we studied the effects of its methanol extract (Mc-ME) on lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages. Specifically, we evaluated nitric oxide (NO) production, mRNA expression of inflammatory genes, luciferase reporter gene activity, and putative molecular targets. Mc-ME blocked NO production in a dose-dependent manner in RAW264.7 cells; importantly, no cytotoxicity was observed. Moreover, the mRNA expression levels of inducible NO synthase (iNOS) and cyclooxygenase (COX)-2 were decreased by Mc-ME treatment in a dose-dependent manner. Luciferase assays and nuclear lysate immunoblotting analyses strongly indicated that Mc-ME decreases the levels of p65 [a nuclear factor (NF)-[Formula: see text]B subunit] and c-Fos [an activator protein (AP)-1 subunit]. Whole lysate immunoblotting assays, luciferase assays, and overexpression experiments suggested that transforming growth factor [Formula: see text]-activated kinase 1 (TAK1) is targeted by Mc-ME, thereby suppressing NF-[Formula: see text]B and AP-1 activity via downregulation of extracellular signal-regulated kinases (ERKs) and AKT. These results strongly suggest that Mc-ME exerts its anti-inflammatory activity by reducing the action of TAK1, which also affects the activation of NF-[Formula: see text]B and AP-1. PMID- 29463101 TI - Autophagy: A Lysosome-Dependent Process with Implications in Cellular Redox Homeostasis and Human Disease. AB - SIGNIFICANCE: Autophagy, a lysosome-dependent homeostatic process inherent to cells and tissues, has emerging significance in the pathogenesis of human disease. This process enables the degradation and turnover of cytoplasmic substrates via membrane-dependent sequestration in autophagic vesicles (autophagosomes) and subsequent lysosomal delivery of cargo. Recent Advances: Selective forms of autophagy can target specific substrates (e.g., organelles, protein aggregates, and lipids) for processing. Autophagy is highly regulated by oxidative stress, including exposure to altered oxygen tension, by direct and indirect mechanisms, and contributes to inducible defenses against oxidative stress. Mitochondrial autophagy (mitophagy) plays a critical role in the oxidative stress response, through maintenance of mitochondrial integrity. CRITICAL ISSUES: Autophagy can impact a number of vital cellular processes including inflammation and adaptive immunity, host defense, lipid metabolism and storage, mitochondrial homeostasis, and clearance of aggregated proteins, all which may be of significance in human disease. Autophagy can exert both maladaptive and adaptive roles in disease pathogenesis, which may also be influenced by autophagy impairment. This review highlights the essential roles of autophagy in human diseases, with a focus on diseases in which oxidative stress or inflammation play key roles, including human lung, liver, kidney and heart diseases, metabolic diseases, and diseases of the cardiovascular and neural systems. FUTURE DIRECTIONS: Investigations that further elucidate the complex role of autophagy in the pathogenesis of disease will facilitate targeting this pathway for therapies in specific diseases. PMID- 29463105 TI - NEET Proteins: A New Link Between Iron Metabolism, Reactive Oxygen Species, and Cancer. AB - SIGNIFICANCE: Cancer cells accumulate high levels of iron and reactive oxygen species (ROS) to promote their high metabolic activity and proliferation rate. However, high levels of iron and ROS can also lead to enhanced oxidative stress and the activation of cell death pathways such as apoptosis and ferroptosis. This has led to the proposal that different drugs that target iron and/or ROS metabolism could be used as anticancer drugs. However, due to the complex role iron and ROS play in cells, the majority of these drugs yielded mixed results, highlighting a critical need to identify new players in the regulation of iron and ROS homeostasis in cancer cells. Recent Advances: NEET proteins belong to a newly discovered class of iron-sulfur proteins (2Fe-2S) required for the regulation of iron and ROS homeostasis in cells. Recent studies revealed that the NEET proteins NAF-1 (CISD2) and mitoNEET (CISD1) play a critical role in promoting the proliferation of cancer cells, supporting tumor growth and metastasis. Moreover, the function of NEET proteins in cancer cells was found to be dependent of the degree of lability of their 2Fe-2S clusters. CRITICAL ISSUES: NEET proteins could represent a key regulatory link between the maintenance of high iron and ROS in cancer cells, the activation of cell death and survival pathways, and cellular proliferation. FUTURE DIRECTIONS: Because the function of NEET proteins depends on the lability of their clusters, drugs that target the 2Fe2S clusters of NEET proteins could be used as promising anticancer drugs.

AB - We investigated whether preprocedural hyperglycemia was associated with contrast induced acute kidney injury (CI-AKI) and long-term outcomes in patients with acute coronary syndrome (ACS) who underwent emergency percutaneous coronary intervention (PCI). Patients (n = 558) with ACS who underwent emergency PCI were consecutively enrolled. Preprocedural hyperglycemia was defined as glucose levels >198 mg/dL (11 mmol/L). The primary outcome was CI-AKI (>=0.3 mg/dL absolute or >=50% relative serum creatinine increase 48 hours after contrast medium exposure). Overall, 103 (18.5%) patients had preprocedural hyperglycemia and 89 (15.9%) patients developed CI-AKI. The incidence of CI-AKI was significantly higher in patients with hyperglycemia than without (28.2% vs 13.2%; P < .01). Multivariate analysis indicated that preprocedural hyperglycemia was an independent predictor of CI-AKI (odds ratio = 1.971, 95% confidence interval [CI]: 1.129-3.441; P < .05). In addition, preprocedural hyperglycemia was associated with an increased risk of all-cause mortality during the 2-year follow up (hazard ratio = 2.440, 95% CI: 1.394-4.273; P = .002). Preprocedural hyperglycemia is a significant and independent predictor of CI-AKI and long-term outcomes.

AB - BACKGROUND: National guidelines recommend angiotensin-converting enzyme (ACE) inhibitors or angiotensin-receptor blockers (ARBs) and beta-blockers (BBs) at target doses for morbidity and mortality benefits in heart failure with reduced ejection fraction (HFrEF); regardless, titration of these therapies in practice remains suboptimal. We implemented an outpatient pharmacist-managed HFrEF medication titration assistance clinic (MTAC) at one institution to improve titration for general cardiology (GC) patients. OBJECTIVE: To evaluate MTAC impact by determining the proportion of patients on target or maximum tolerated ACE inhibitor/ARB and BB doses. METHODS: A retrospective chart review of adult patients with documented ejection fraction <=40% managed in the MTAC or GC from 2011 to 2013 was conducted. HFrEF medication regimens were collected at initial visit and months 1, 2, 3, 6, 9, and 12 to assess titration. Target doses were defined per guideline or dose at which ejection fraction recovered during the study. Maximum tolerated doses were defined as the highest dose patients tolerated without physiological limitations. RESULTS: Of 148 patients, the MTAC managed 51 and GC managed 97. At baseline, 90% of MTAC versus 82% of GC patients were prescribed ACE inhibitors/ARBs and BBs. In the MTAC, 4% were at target or maximum tolerated doses compared with 32% of GC patients ( P < 0.001). At 12 months, 95% of patients in the MTAC and 87% in GC were prescribed ACE inhibitors/ARBs and BBs. Of those prescribed ACE inhibitors/ARBs and BBs, 64% in the MTAC versus 40% in GC reached target or maximum tolerated doses ( P = 0.01). CONCLUSIONS: The pharmacist-managed MTAC increased the proportion of patients on optimal HFrEF therapies and are a resource for GC patients.

AB - BACKGROUND AND OBJECTIVES: Parenting a child with Autism Spectrum Disorder (ASD) is challenging and can result in elevated levels of parenting stress. This study investigated the relationship between parent-ratings of their child's ASD symptoms and two conceptually different measures of parenting stress: One specific to the ASD context and the other a general stress measure applicable to the broader caregiving context. Additionally, the influence of coping style on the relationship between child's ASD symptoms and parenting stress was investigated. DESIGN AND METHODS: Using an internet survey, parents (N = 178) caring for a child with ASD reported on coping strategies, completed two measures of parenting stress, and assessed their child's ASD symptoms. RESULTS: Parenting stress increased with severity of the child's ASD symptoms, but the strength of this relationship depended on whether a general or disorder-specific measure of parenting stress was used. Regression analyses indicated that some coping strategies moderated the impact of ASD symptom severity on the parent's care related stress, but moderation depended on how stress was conceptualized. CONCLUSION: This study reinforces the importance of identifying the coping strategies of parents of children with developmental disorders, and highlights the consequences of using different conceptual approaches to measure parenting stress.

AB - In this study, the effect of doxorubicin, flavonoid extract of white Morus alba leaf (MFE) and a combination of doxorubicin and flavonoid extract on Bax and Bcl2 levels and caspase 3 activity of cancer A-172 GBM cell line was investigated. Bax/Bcl2 levels of treated A-172 GBM cell line with flavonoid extract of white mulberry leaf were estimated by ELISA methods. Caspase 3 activity of treated A 172 GBM cells was determined by calorimetric assay. The flow cytometry assessment was used to estimate the apoptosis percent of treated A-172 GBM cells. Treatment of A-172 GBM cells with MFE, doxorubicin and a combination of MFE and doxorubicin caused a significant decrease in Bcl2 level and an increase in Bax level. The apoptosis percent of treated cells were also elevated significantly. Present results suggest that concomitant use of herbal medicine and chemotherapy may be an effective alternative method for the treatment of cancers. PMID- 29463110 TI - The importance of the therapeutic relationship when providing information to parents of children with long-term disabilities: The views and experiences of UK paediatric therapists. AB - The purpose of this study was to understand the views and experiences of paediatric therapists working in the United Kingdom regarding the importance of the therapeutic relationship when providing information for parents of children with long-term disabilities. The aim was to develop new perspectives, to encourage dialogue and reflection for change and to identify practical suggestions for health professionals when developing therapeutic relationships. This study employed an interpretive phenomenological methodology. Semi structured, in-depth interviews were carried out with seven health professionals from a single National Health Service trust in the United Kingdom (children's physiotherapists, occupational therapists and speech therapists). Resultant data were analysed using a systematic process of thematic content analysis. One main theme 'The Importance of the Therapeutic Relationship: Balancing a Positive Relationship with Professional Responsibility' is presented and discussed. Paediatric therapists recognize that fostering a positive therapeutic relationship is vital to facilitate parental engagement with the information they provide. Despite this it was felt that efforts to maintain a positive relationship needed to be carefully balanced with discharging professional responsibility to the child. A preliminary model 'The Therapeutic Relationship Continuum' is presented, aiming to help health professionals self-assess and reflect on the dynamic interface between the therapeutic relationship and information provision.

AB - Five new pinocembrin derivatives (MC1-MC5) were synthesized by Steglich reaction, and investigated for their antimicrobial, antioxidant, and anti-inflammatory activity. MC2 (oleoyl derivative) and MC3 (linoleoyl derivative) have shown the highest inhibitory effects on bacterial proliferation, with MIC values of 32 MUg/mL against Staphylococcus aureus. The docosahexaenoyl derivative MC5 displayed the highest anti-inflammatory activity, decreasing NO production in LPS stimulated macrophages with an IC50 value of 15.51 MUg/mL higher than the positive control diclofenac (IC50 of 39.71 MUg/mL). All new synthesized compounds showed no anti-proliferative effects on RAW 264.7 cells. Results demonstrated as the introduction of fatty acid substituents improved the biological profile of pinocembrin. Moreover, the chemical nature of substituents significantly affects the bioactivity. These preliminary results outline the importance to investigate the synthesis of pinocembrin fatty acids derivatives as new and safe anti microbial/anti-inflammatory agents.

AB - BACKGROUND: The Mayas of the State of Yucatan in Mexico are the only aboriginal group with obesity and diabetes data before 1997. OBJECTIVE: To analyze socioeconomic trends associated with the increase in obesity and diabetes seen in rural Yucatan from 1962 to 2000. METHODS: Body weight, height and venous Fasting Blood Glucose (FBG) were measured in 263 rural Maya adults participating in a 2000 nutrition survey. RESULTS: Diabetes (FBG > 125 mg/dL) and obesity (BMI >= 30 kg/m2) were 10.6% and 35.7%, respectively. These results contrast with those of a 1962 survey where diabetic prevalence was 2.3% and 0% in women and men respectively, with widespread adult pellagra and malnutrition. An important socioeconomic transition that took place in Yucatan during this lapse appeared to be associated to the obesity and diabetes increase. CONCLUSIONS: Rural Yucatan evolved from malnutrition conditions to high prevalence of obesity and diabetes in less than 40 years. This change was associated with the transition from an agroindustry-based economy, characterized by high-energy expenditure and low protein intake, to lower energy requirements of a Government-subsidized economy with larger food supply. PMID- 29463113 TI - Pediatric Lip Adhesion Following Bullous Erythema Multiforme and Review of Similar Oral Complications. AB - BACKGROUND: Erythema multiforme (EM) is a mucocutaneous disease most often associated with preceding herpes simplex virus or Mycoplasma pneumoniae infection. It is characterized by targetoid lesions occurring on the limbs and head and neck. Mucosal involvement can be extensive. OBJECTIVE: We report a case of lip adhesion as a complication of EM in a child who required corrective surgery and review similar oral commissure complications. METHODS: We completed a review of the literature for similar cases using PubMed and Medline. CONCLUSIONS AND RELEVANCE: We present the youngest report of lip adhesion due to striking mucositis related to EM. Sequelae of erythema multiforme can be significant, in our case requiring surgery. Meticulous oral hygiene should be encouraged when mucosal lesions are identified.

AB - Comparative effectiveness research (CER) guidelines have been developed to direct the field toward the most rigorous study methodologies. A challenge, however, is how to ensure the best evidence is generated, and how to translate methodologically complex or nuanced CER findings into usable medical evidence. To reach that goal, it is important that both researchers and end users of CER output become knowledgeable about the elements that impact the quality and interpretability of CER. This paper distilled guidance on CER into a practical tool to assist both researchers and nonexperts with the critical review and interpretation of CER, with a focus on issues particularly relevant to CER in oncology.

AB - Whole-body systemic gene therapy is likely the most effective way to reduce greatly the disease burden of Duchenne muscular dystrophy (DMD), an X-linked inherited muscle disease that leads to premature death in early adulthood. Genetically, DMD is due to null mutation of the dystrophin gene, one of the largest genes in the genome. Recent studies have shown highly promising improvements in animal models with intravascular delivery of the engineered micro dystrophin gene by adeno-associated virus (AAV). Several human trials are now started to advance AAV micro-dystrophin therapy to DMD patients. This is a historical moment for the entire field. Results from these trials will shape the future of neuromuscular disease gene therapy. PMID- 29463118 TI - Clinical contribution of myositis-related antibodies detected by immunoblot to idiopathic inflammatory myositis: A one-year retrospective study. AB - In this study, we aimed at evaluating the contribution of an extended myositis related antibodies (Abs) determination by immunoblot to the diagnosis, classification, and prognosis of idiopathic inflammatory myositis (IIM). Medical records of all the patients (n = 237) with myositis-related Ab requests addressed to our department over a one-year period were retrospectively analyzed. Patients were classified as IIM, auto-immune disease (AID) other than IIM, and other diagnosis, and examined for their Ab profiles as determined by immunoblot. Ab positivity was qualified semi-quantitatively as low or strong according to the manufacturer's recommendations. Among the 45 Ab-positive patients, 49% were diagnosed an IIM, 22% another AID, and 29% another diagnosis. The clinico serological patterns of the myositis-related Ab+ patients fully recapitulated those described in the literature. Among non-IIM patients, anti-PM-Scl was the most frequently detected Ab (38%), followed by anti-Mi-2 (15%), and anti-OJ (12%). Importantly, strong Ab positivity was significantly more detected in IIM vs. non-IIM patients (82% vs. 35%; p = .002). This difference was further increased when comparing MSAs only (95% vs. 36%; p = .0004). Accordingly, strong Ab positivity associated with high specificity (96%) and positive likelihood ratio (pLR =12) for IIM. Our data suggest that while myositis-related Ab, including MSA, can be detected by immunoblot in non-IIM patients, strong positivity is nevertheless highly predictive of IIM. In conclusion, this work suggests that relevant clinical contribution to IIM is provided by the immunoblot determination of myositis-related Ab, more especially when considering strong positive detection of MSA.

AB - Earlier intention-to-treat (ITT) findings from a community-randomized trial demonstrated effects of the Communities That Care (CTC) prevention system on reducing problem behaviors among youth. In ITT analyses, youth were analyzed according to their original study community's randomized condition even if they moved away from the community over the course of follow-up and received little to no exposure to intervention activities. Using inverse probability weights (IPWs), this study estimated effects of CTC in the same randomized trial among youth who remained in their original study communities throughout follow-up. Data were from the Community Youth Development Study, a community-randomized trial of 24 small towns in the United States. A cohort of 4,407 youth was followed from fifth grade (prior to CTC implementation) to eighth grade. IPWs for one's own moving status were calculated using fifth- and sixth-grade covariates. Results from inverse probability weighted multilevel models indicated larger effects for youth who remained in their study community for the first 2 years of CTC intervention implementation compared to ITT estimates. These effects included reduced likelihood of alcohol use, binge drinking, smokeless tobacco use, and delinquent behavior. These findings strengthen support for CTC as an efficacious system for preventing youth problem behaviors.

AB - In this article, we review three innovative methods: multiform protocols, visual analog scaling, and the retrospective pretest-posttest design that can be used in evaluation research. These three techniques have been proposed for decades, but unfortunately, they are still not utilized readily in evaluation research. Our goal is to familiarize researchers with these underutilized research techniques that could reduce personnel effort and costs for data collection while producing better inferences for a study. We begin by discussing their applications and special unique features. We then discuss each technique's strengths and limitations and offer practical tips on how to better implement these methods in evaluation research. We then showcase two recent empirical studies that implement these methods in real-world evaluation research applications. PMID- 29463121 TI - Assessment of Factors Influencing Communication in Clinical Pharmacy. AB - This study aimed to identify and assess the factors that influence communication quality between clinical pharmacists and patients using a structural equation model based on the predisposing, reinforcing, and enabling constructs in educational/environmental diagnosis and evaluation-policy, regulatory, and organizational constructs in educational and ecological development model to identify the most effective path to increase their communication quality. A survey was conducted at 253 Class-A tertiary hospitals in China from March to December 2016. During on-site observations, verbal communications between clinical pharmacists ( n = 752) and patients were audio recorded, and communication quality was rated by an expert panel on an 8-item Quality of Communication Rating Scale. Clinical pharmacists completed questionnaires that examined the predisposing, enabling, and reinforcing factors that influenced communication quality. Finally, AMOS was employed to examine the relationships between the three factors and communication quality. The results indicated that all three factors positively affected communication quality, with correlation coefficients of .26, .13, and .17, respectively. The most influential predisposing factor was attitude (.77), the most influential enabling factors were self-efficacy (.71) and confidence (.72), and the most influential reinforcing factor was rewards (.74). The findings suggest that pharmacists' attitudes toward, perceived knowledge of, and skill and confidence in communication, and the rewards offered by pharmacy management are the most influential factors that influence communication quality. PMID- 29463122 TI - Evaluation and Comparison of Contemporary Energy-Based Surgical Vessel Sealing Devices. AB - INTRODUCTION: We evaluated and compared five currently available energy-based vessel sealing devices to assess typical surgical metrics. METHODS: We tested Caiman 5 (C5), Harmonic Scalpel Ace Plus (HA), Harmonic Ace +7 (HA7), LigaSure (LS), and Enseal G2 (ES) on small (2-5 mm), medium (5.1-7 mm), and large (7.1-9 mm) vessels obtained from 15 Yorkshire pigs. Vessels were randomly sealed and transected. We recorded sealing and transection time, charring and carbonization, thermal spread, and bursting pressure (BP). Specimens were sent for histopathologic evaluation of seal quality and thermal spread. RESULTS: A total of 246 vessels were evaluated: 125 were arteries and 121 were veins. There was no difference in BPs for small size arteries. For medium arteries, C5 provided the highest BP (proximal and distal jaw), followed by HA7, ES, LS, and HA [1740, 1600, 1165, 1165, 981, and 571 mm Hg, respectively, HA250 mm Hg. PMID- 29463124 TI - Designed construction of tween 60@2beta-CD self-assembly vesicles as drug delivery carrier for cancer chemotherapy. AB - We report a simple strategy to prepare Tween 60@2beta-CD self-assembly vesicles in aqueous solution as a new drug delivery carrier for cancer chemotherapy. The spherical shape of vesicles was confirmed by transmission electron microscopy (TEM) and mean particle sizes were about 33.7 nm, as measured by dynamic light scattering, micro-IR results indicated that the self-assembly vesicles was driven by hydrogen bonding. Hydrophilic doxorubicin (DOX) was successfully loaded into the self-assembly vesicles with drug loading content of 7.85% and loading efficiency of 42%. In addition, an in vitro cytotoxicity study and cellular uptake assays demonstrated that the DOX-loaded Tween 60@2beta-CD vesicles markedly enhanced the cellular uptake and cytotoxicity of DOX toward the Hela cells. Furthermore, when used to evaluate the in vivo therapeutic efficacy in mice bearing the breast cell line (4T1), DOX-loaded vesicles exhibited superior inhibition of tumor growth compared with the DOX solutions. PMID- 29463123 TI - Novel application of pluronic lecithin organogels (PLOs) for local delivery of synergistic combination of docetaxel and cisplatin to improve therapeutic efficacy against ovarian cancer. AB - The synergistic combination of docetaxel (DTX) and cisplatin (CIS) by local drug delivery with a pluronic lecithin organogel (PLO) to facilitate high drug concentrations at tumor sites and less nonspecific distribution to normal organs is thought to be beneficial in chemotherapy. In this study, using Capryol-90 (C90) with the addition of lecithin as the oil phase was developed to carry DTX, which was then incorporated into a PLO-containing CIS to formulate a dual-drug injectable PLO for local delivery. An optimal PLO composite, P13L0.15O1.5, composed of PF127:lecithin:C90 at a 13:0.15:1.5 weight ratio was obtained. The sol-gel transition temperature of P13L0.15O1.5 was found to be 33 degrees C. Tumor inhibition studies illustrated that DTX/CIS-loaded P13L0.15O1.5 could efficiently suppress tumor growth by both intratumoral and peritumoral injections in SKOV-3 xenograft mouse model. Pharmacokinetic studies showed that subcutaneous administration of P13L0.15O1.5 was able to sustain the release of DTX and CIS leading to their slow absorption into the systemic circulation resulting in lower area under the plasma concentration curve at 0-72 h (AUC0-72) and maximum concentration (Cmax) values but longer half-life (T1/2) and mean residence time (MRT) values. An in vivo biodistribution study showed lower DTX and CIS concentrations in organs compared to other treatment groups after IT administration of the dual drug-loaded P13L0.15O1.5. It was concluded that the local co-delivery of DTX and CIS by PLOs may be a promising and effective platform for local anticancer drug delivery with minimal systemic toxicities. PMID- 29463125 TI - Salbutamol in acute organophosphorus insecticide poisoning - a pilotdose-response phase II study. AB - BACKGROUND: Treatment of acute organophosphorus (OP) insecticide poisoning is difficult, with many patients dying despite best care. Pre-clinical studies have shown benefit from salbutamol, possibly due speeding alveolar fluid clearance or reducing bronchoconstriction. In this small pilot dose-response study, we aimed to explore whether addition of nebulized salbutamol to standard care might improve resuscitation. METHODS: We performed a single-blind phase II study comparing the effect of two different doses of nebulized salbutamol versus saline placebo, in addition to standard treatment. Primary outcome was oxygen saturations over the first 60 min of resuscitation; secondary outcomes included heart rate, incidence of dysrhythmias, time to 'atropinization', atropine dose required, and mortality. RESULT: Seventy-five patients were randomized to receive 5 mg (Salb5, n = 25) or 2.5mg (Salb2.5, n = 25) of salbutamol, or saline placebo (NoSalb, n = 25), by nebulizer. Oxygen saturations did not differ between groups over the first 60 min of resuscitation (median AUC NoSalb: 1376 [95% CI 1282 to 1470], Salb2.5: 1395 [1305 to 1486], Salb5: 1233 [1100 to 1367]; p = .9898). Heart rate was also similar across the three arms. Median time to full atropinization, and atropine dose required, were the same for all three arms (NoSalb 15.0 [10-16] min and 12.6 [8.0-13.4] mg, Salb2.5 15.0 [10-16] min and 12.6 [9.3-16.8] mg, and Salb5 15.0 [10-20] min and 12.6 [10.7-20.6] mg; p = .4805 and p = .1871, respectively). Three (12%) patients died in the Salb2.5 and Salb5 groups and two (8%) in the NoSalb group. CONCLUSION: This pilot study, within the limitations of its small size and variation between patients, found no apparent evidence that administration of nebulized salbutamol improved resuscitation of patients with acute OP insecticide self-poisoning. The data obtained provides a basis to design further studies to ultimately test the role of salbutamol in OP insecticide poisoning. PMID- 29463126 TI - Comparative Study of Internal Fixation of the Ulna and Distal Ulna Resection in Patients Older Than 70 Years With Distal Radius and Distal Metaphyseal Ulna Fractures. AB - BACKGROUND: Acute management of fractures of the distal ulna that are associated with fractures of the distal radius remains difficult, particularly in the elderly. METHODS: In this study, we investigated whether internal fixation of the distal ulna is associated with a higher rate of complications than resection of the distal ulna in patients older than 70 years. Twenty-four consecutive patients were included in this study, 12 of whom had undergone open reduction and internal fixation (ORIF) of the distal ulna, and 12 who had undergone distal ulna resection. Patients were retrospectively assessed for range of motion, grip strength, pain, and radiographic appearance. The functional outcome was evaluated by the Mayo Wrist Score. Complications were classified according to the Classification of Surgical Complications. RESULTS: There were no differences in patient demographics between the 2 groups, except patient age. Clinical evaluation showed no difference at follow-up; however, there were significantly more complications associated with ORIF compared with resection. CONCLUSIONS: The results from our study show that women older than 70 years with fracture of the distal radius and distal ulna have a higher rate of complications if ORIF of the distal ulna is performed. Patients should be warned, by surgeons, of this in cases where ORIF of the distal ulna is suggested.

AB - BACKGROUND: We made a tin ring splint for osteoarthritis of the distal interphalangeal joint that looks attractive and is easy to wear. We report the treatment results with this splint. METHODS: We enrolled 30 patients with painful osteoarthritis of the distal interphalangeal joint in this study. A tin ring splint was made with tin alloy containing small quantities of silver. Patients were instructed to wear the splint when they felt pain. Patients were assessed before splint use and after 1, 3, and 6 months of splint use. Endpoints included the numeric pain scale, active arc of motion of the distal interphalangeal joint, Hand 20, functional assessment criteria of the upper extremities, and treatment satisfaction. In addition, data were collected on time to symptom relief and satisfaction related to usability and appearance of the splint (0 = dissatisfied, 10 = satisfied). RESULTS: The numeric pain scale showed significant pain improvement from 58.4 +/- 4.1 at baseline to 33.1 +/- 4.5 at 1 month, and the Hand 20 score also showed significant improvement from 35.0 +/- 4.3 at baseline to 20.2 +/- 3.2 after 6 months. Active arc of motion were not changed significantly. Most patients responded that symptoms were relieved by the 10th day after treatment. Satisfaction related to usability was 8.9 +/- 0.3, and appearance was 7.6 +/- 0.4. CONCLUSIONS: A tin ring splint quickly reduced pain, and satisfaction related to usability and appearance was high. This splint could be one choice for conservative treatment of osteoarthritis of the distal interphalangeal joint. PMID- 29463128 TI - Distal Scaphoid Excision in Treatment of Symptomatic Scaphoid Nonunion: Systematic Review and Meta-analysis. AB - BACKGROUND: Current treatment options for persistent scaphoid nonunion are limited to salvage procedures such as proximal row carpectomy (PRC) or 4-corner fusion (4CF). Several small studies have demonstrated that distal scaphoid excision may provide a simpler alternative with faster recovery. The purpose of this study was to determine the efficacy of distal scaphoid excision as a treatment option for symptomatic scaphoid nonunion. METHODS: The MEDLINE and PubMed databases were searched for the use of distal scaphoid excision in scaphoid nonunions. Studies included reported on either the functional or patient centered outcomes following distal scaphoid excision for symptomatic scaphoid nonunion. RESULTS: Six articles described the outcomes of 70 patients with an average of 11.7 patients per study. Functional outcomes including flexion extension arc, radial-ulnar deviation, and grip strength improved by an average of 98.95%, 58.96%, and 131.08%, respectively. Patient-derived outcomes included the Modified Mayo Wrist Score, which improved by 92.6%, and the Disabilities of the Arm, Shoulder and Hand, which improved by 137.17%. An average of 68.75% of patients experience complete relief of pain with 20.83% of patients experiencing pain with strenuous activity. The average postoperative visual analog scale (0 10) was 0.71. On average, 93.33% of patients returned to work with an average time of return being 6.89 weeks. Complete satisfaction was reported by 87.80% of patients. Complications included progression into 4CF or PRC and newly developed midcarpal arthritis. CONCLUSIONS: Given favorable outcomes, our analysis suggests that distal scaphoid excision may be a favorable, low-risk treatment for scaphoid nonunion without eliminating more extensive options such as 4CF and wrist arthrodesis. PMID- 29463129 TI - Antifungal activity of Annona coriacea Mart. ethanol extracts against the aetiological agents of cryptococcosis. AB - Cryptococcosis is an opportunistic disease with a worldwide distribution. This disease is caused by fungi of the genus Cryptococcus, and its treatment is limited to several antifungals. In this study, the antifungal, cytotoxic and mutagenic properties of ethanol extracts from the bark and leaves of Annona coriacea were evaluated against the standard Cryptococcus species and clinical yeast specimens. Both extracts of A. coriacea showed inhibitory activity of 1.5 mg/mL for all of the yeasts tested. The number of viable cells at the lowest tested concentration was 0.187 mg/mL. The extracts that were tested showed inhibitory activity and reduced the fungal growth of the Cryptococcus gattii species and Cryptococcus neoformans species complexes, suggesting that this plant may be an effective alternative treatment for cryptococcosis.

AB - INTRODUCTION: Though cervical cytology, HPV DNA testing, and pre-invasive disease management has significantly reduced the number of new diagnoses of cervical cancer, women with persistent oncogenic HPV infection are at significant risk for developing invasive cervical cancer. Early stage and locally advanced disease can be cured, but women with advanced or recurrent disease have a very poor prognosis. This underscores the need for different treatment strategies for advanced cervical cancer, the most promising of which are novel therapeutics that target the ability of HPV to overcome host immune tolerance. Areas covered: This review includes new therapies being investigated for the treatment of recurrent, metastatic or refractory cervical cancer, separated into broad categories of cellular and non-cellular based strategies. Expert opinion: Advanced and recurrent cervical cancer has a poor prognosis, prompting investigations into the development of strategies that will eradicate tumor and/or overcome host immunologic tolerance of disease. It is unknown whether it will be these strategies alone or a combination of treatment modalities that will ultimately provide the best outcomes; nevertheless, the new data are promising. PMID- 29463132 TI - Long-term metabolic cage housing increases anxiety/depression-related behaviours in adult male rats. AB - There are several reports on unfavourable effects of metabolic cage housing on animal welfare mainly due to the characteristic structures of these cages such as single housing and grid flooring. This study was aimed to compare the effects of long-term metabolic cage housing and conventional housing (normal grouped housing in standard cages) on the anxiety/depression-like behaviours in male rats. Anxiety/depression-related behaviours were evaluated by use of forced swimming test and open field test. Swimming and climbing were significantly lower and immobility duration higher in the metabolic cage group. In the open field test, total distance, mean velocity, time spent in the central area, zone transition, grooming, and rearing scores were significantly lower in the metabolic cage. Moreover, serum corticosterone level was higher in the metabolic cage group. The results of the study indicate that long-term metabolic cage housing may cause an increase in the anxiety- and depression-related behaviours in male rats.

METHODS: NAFLD rats were organised in patient, saline, resveratrol (RSV), continuous exercise, interval exercise, continuous exercise + RSV, and interval exercise + RSV groups. RESULTS: Resveratrol supplementation alone or in combination with interval and continuous training significantly decreased malondialdehyde and TNF-alpha level (p < .05), while the levels of catalase; superoxide dismutase and IL-10 were significantly increased (p < .05). Although RSV alone significantly decreased the percentage of apoptotic cells (17.12%), its combination with interval (10.74%), and continuous (14.85%) exercise training demonstrated higher anti-apoptotic activity (p < .05). CONCLUSIONS: Although resveratrol alone has an antioxidant, anti-apoptotic and anti-inflammatory properties, combined therapy with interval, and continuous training can be more effective to mitigate these abnormalities in NAFLD patients.

AB - BACKGROUND: Theatre-based interventions use artistic media to facilitate social and emotional awareness and have therapeutic benefits for persons with developmental disabilities and mental health problems. The role of these interventions with Indigenous youth who have emotional, behavioural, and cognitive sequelae related to fetal alcohol spectrum disorder (FASD) has not been explored. PURPOSE: The purpose of this study was to explore the experiences and acceptability of a theatre-based approach for facilitating social communication and engagement in youth with FASD. METHOD: Participants were three Indigenous youth with FASD. A qualitative exploration of the experiences and acceptability of the intervention was conducted via focus groups held 2 weeks post-program participation with the participants, their caregivers, and program facilitators. The transcripts were analyzed using an inductive thematic approach. FINDINGS: Our results identified perceived postintervention improvements in participants' development of self-esteem, social skills, and emotional awareness. IMPLICATIONS: A theatre-based arts intervention has the potential to support improvements in social skills for youth with FASD. PMID- 29463136 TI - In Vitro Analysis of Cartilage Regeneration Using a Collagen Type I Hydrogel (CaReS) in the Bovine Cartilage Punch Model. AB - Objective Limitations of matrix-assisted autologous chondrocyte implantation to regenerate functional hyaline cartilage demand a better understanding of the underlying cellular/molecular processes. Thus, the regenerative capacity of a clinically approved hydrogel collagen type I implant was tested in a standardized bovine cartilage punch model. Methods Cartilage rings (outer diameter 6 mm; inner defect diameter 2 mm) were prepared from the bovine trochlear groove. Collagen implants (+/- bovine chondrocytes) were placed inside the cartilage rings and cultured up to 12 weeks. Cartilage-implant constructs were analyzed by histology (hematoxylin/eosin; safranin O), immunohistology (aggrecan, collagens 1 and 2), and for protein content, RNA expression, and implant push-out force. Results Cartilage-implant constructs revealed vital morphology, preserved matrix integrity throughout culture, progressive, but slight proteoglycan loss from the "host" cartilage or its surface and decreasing proteoglycan release into the culture supernatant. In contrast, collagen 2 and 1 content of cartilage and cartilage-implant interface was approximately constant over time. Cell-free and cell-loaded implants showed (1) cell migration onto/into the implant, (2) progressive deposition of aggrecan and constant levels of collagens 1 and 2, (3) progressively increased mRNA levels for aggrecan and collagen 2, and (4) significantly augmented push-out forces over time. Cell-loaded implants displayed a significantly earlier and more long-lasting deposition of aggrecan, as well as tendentially higher push-out forces. Conclusion Preserved tissue integrity and progressively increasing cartilage differentiation and push-out forces for up to 12 weeks of cultivation suggest initial cartilage regeneration and lateral bonding of the implant in this in vitro model for cartilage replacement materials.

AB - BACKGROUND: Overweight and obesity are one of the most serious clinical health problems. Until now, the long-term development of children born to mothers after transplantation is unknown. In this study, we attempted to present the analysis of the prevalence of overweight in the population of mothers after kidney or liver transplants. METHODS: A comparison of body mass index (BMI) measurements performed in 61 children of kidney transplant women (study group) and 64 children born to healthy mothers (control group). The children from both groups were born at a similar gestational age and in the similar time period from 12/1996 to 11/2010. BMI was measured once on one of the follow-up visits in the time period from 07/2010 to 11/2013. BMI was assessed in infants older than one month as well as in toddlers or children in the preschool or school age. The results obtained in the study group of children born to transplanted mothers were compared with control group results and with the theoretical population data. RESULTS: There were no differences in the incidence of underweight and overweight, when BMI values of children born to transplanted mothers were compared to those of children of healthy mothers. There was a trend towards a greater incidence of obesity in children of studied group compared to controls (16 versus 6%, p = .072). Among analysed factors, it was noted that prenatal exposure to tacrolimus was associated with a 2.8-fold increased risk of developing a higher BMI in later follow-up. CONCLUSIONS: Obesity among children of mothers after kidney or liver transplants seems to be more frequently observed. This observation may be an important factor in the further paediatric care, especially in children born to transplanted mothers treated chronically with tacrolimus.

PMID- 29463139 TI - Non-persistent pesticides in breast milk in an agricultural area in Turkey. AB - BACKGROUND: Organophosphates, pythyreoids, carbamate pesticides and fungicides are heavily used in agriculture. They may have dangerous effects on newborn health especially on immune system and growth via prenatal transmission by placenta or postnatal transmission by breastfeeding. METHODS: In 2015, 144 non persistent pesticides in 64 milk samples of 32 mothers were studied by OuEChERS method in liquid chromatography/tandem mass spectrometer in neonatal Intensive Care Unit in Adana, a city in Cukurova region which is an important agricultural area in Turkey. RESULTS: Pesticides were detected in milk samples of 11 mothers (34.3%) and 21 (32.8%) of milk samples. In five mothers, fungicides (in 5/10 samples propicanozole-PP, in 4/10 samples bromucanozole-BM), in five mothers, organophosphates (in 10/10 samples primyphosphomethyl-PPM), in one mother, both organophosphates and fungicide (in 1/2 samples PPM and in 1/2 samples buprimate) were detected. However, the estimated daily intakes (EDI) were less than acceptable daily intakes (ADI) for PPM, PP and BM, respectively. CONCLUSIONS: Although pesticides levels in human milk did not exceed the ADIs, we suggest monitoring pesticides in human breast milk especially for newborn health. PMID- 29463140 TI - Premature ventricular beats in the athlete: management considerations. AB - INTRODUCTION: Premature ventricular beats (PVBs) in competitive athletes are incidentally found during pre-participation ECG screening. Their clinical significance remains debatable with several studies suggesting they are a benign reflection of athlete's heart, and others proposing they may indicate underlying structural heart disease and heightened risk for sudden cardiac death (SCD). Areas covered: Effective management of athletes with PVBs may best be accomplished using an algorithmic approach for risk stratification with a goal of differentiating benign PVBs from those reflective of underlying cardiomyopathies. Current AHA/ACC consensus recommendations provide a platform for determining optimal medical and invasive therapeutic strategies for symptom control and management of long-term complications without erroneously restricting an athlete's ability to play. Utilizing a shared decision-making model is an optimal method for managing expectations and guiding exercise recommendations. Expert commentary: Though pre-participation ECG screening as the standard of care for competitive athletes remains controversial in the United States, a 12-lead ECG is often the first indication of underlying structural heart disease in athletes with PVBs and can therefore identify athletes at greater risk of SCD. Advancements in non-invasive imaging continue to improve in diagnostic potential and prognostication. Invasive therapies provide a curative strategy for refractory PVBs and PVB-induced cardiomyopathy. PMID- 29463141 TI - The Normative Nature of Aggressive Intrusive Thinking Among an Underserved Incarcerated Population Compared With a Student Sample. AB - Aggressive intrusive thoughts (AITs) are unwanted and repetitive thoughts, impulses, or desires that enter into consciousness involuntarily. The current study compared the frequency of and distress from AITs in a sample of inmates jailed for violent crimes ( n = 78) versus college students ( n = 103; that is, participant status). The relationship between psychopathic traits and AITs was also explored. Results indicated that, although there were no differences between students and inmates, AIT frequency was positively associated with Primary Psychopathy. However, there was no significant interaction between participant status (i.e., inmate vs. student) and psychopathy. Finally, there were no significant main or interactions effects in the model predicting AIT distress. These findings demonstrate that AIT frequency is a normative cognitive experience that occurs in both nonviolent and violent individuals, and provides further evidence for an association between psychopathic traits and unwanted aggressive cognition. PMID- 29463142 TI - Levonorgestrel emergency contraceptive pills use during breastfeeding; effect on infants' health and development. AB - OBJECTIVE: The current study aims to evaluate the effect of the use of single packet of levonorgestrel emergency contraceptive pills (LNG-ECPs) during breastfeeding on the health and development of the nursing infant. MATERIALS AND METHODS: The current study was an ancillary observational cohort study carried out in a university hospital. We counseled all women delivered and planning birth space and breastfeed for at least 1 year for participation during postpartum hospital stay. Eligible participants for inclusion in the randomized controlled trial (NCT 01111929) were allocated to receive adequate Lactational Amenorrhea Method (LAM) counseling (LAM-only group) or the LAM counseling in addition to counseling about LNG-ECPs use (LAM + emergency contraception (EC) group). These pills were to be used once if unprotected intercourse did occur after expiry of any of the LAM prerequisites and before the couples started to use a reliable method of contraception. We included the first 100 women in the LAM + EC who did use the pills and the first 100 women in the control group who completed the follow-up visits for 6 months to draw the infants' outcome. The primary outcome was the difference of anthropometric measurements of the infants at 3 and 6 months postpartum. Secondary outcome was the difference in the Psycho-social, fine and gross motor, and language development using Denver development screening test. RESULTS: There were no statistical significant differences between both the groups regarding the infants' weight, length, head circumference, chest circumference, and mid-arm circumference at each visit (p > .05). Additionally, there were no statistically significant differences regarding all items (psycho social, fine and gross motor, and language) of Denver development screening test between the infants in LAM-only and LAM + EC groups (p = .081). CONCLUSIONS: The use of single packet of LNG-ECPs during breastfeeding not objectively affects health and development of nursing infants or subjectively affects the quantity of breast milk. PMID- 29463143 TI - Estimated impact of rotavirus vaccine on hospitalizations and deaths from rotavirus diarrhea among children <5 in Asia. AB - BACKGROUND: Of the 215,000 global deaths from rotavirus estimated in 2013, 41% occur in Asian countries. However, despite a recommendation for global rotavirus vaccination since 2009, only eight countries in Asia have introduced the rotavirus vaccine into their national immunization program as of September 2017. To help policy makers assess the potential value of vaccination, we projected the reduction in rotavirus hospitalizations and deaths following a hypothetical national introduction of rotavirus vaccines in all countries in Asia using data on national-level rotavirus mortality, <5 population, rotavirus hospitalizations rates, routine vaccination coverage, and vaccine effectiveness. METHODS: To quantify uncertainty, we generated 1,000 simulations of these inputs. RESULTS: Our model predicted 710,000 fewer rotavirus hospitalizations, a 49% decrease from the 1,452,000 baseline hospitalizations and 35,000 fewer rotavirus deaths, a 40% decrease from the 88,000 baseline deaths if all 43 Asian countries had introduced rotavirus vaccine. Similar reductions were projected in subanalyses by vaccine introduction status, subregion, and birth cohort size. CONCLUSION: Rotavirus vaccines will substantially reduce morbidity and mortality due to rotavirus infections in Asia.

AB - OBJECTIVE: The objective of this study is to assess the diagnostic accuracy of a novel hypothermia monitoring and alert bracelet device (BEMPU Bracelet) in low birth weight (LBW) neonates weighing less than 2000 g. DESIGN: This was a controlled prospective study. SETTING: This study was done in the step-down nursery of a tertiary level newborn unit of a major teaching hospital in India. METHODS: Eligible cases fulfilling inclusion criteria were given BEMPU Bracelets for a period of 24 h. A comparison was made between skin temperatures taken at the axilla by a mercury thermometer and skin temperatures taken at the wrist by the BEMPU Bracelet. Temperatures were taken every 6 h and every time the BEMPU Bracelet alarmed. Trained nurses obtained temperature measurements on newborns during their 24-h stay in the hospital step-down nursery. RESULTS: A total of 461 neonates were screened for hypothermia, giving 2428 temperature readings. Three hundred and eleven of 461 babies experienced hypothermia at some point. The 461 babies studied experienced 495 episodes of hypothermia in total. The sensitivity and the specificity of the bracelet in diagnosing hypothermia were 98.6% and 95% respectively. The positive and negative predictive values of the bracelet were 83.6% and 99.6%, respectively. The accuracy of the bracelet in diagnosing hypothermia was 95.8%. CONCLUSION: The BEMPU Bracelet is an accurate screening tool to detect and alert for neonatal hypothermia, thereby facilitating prompt management, which could prevent complications. PMID- 29463145 TI - LVIS Jr. stent for treatment of intracranial aneurysms with parent vessel diameter of 2.5 mm or less. AB - Background and purpose This retrospective study evaluates the safety, effectiveness, and long-term clinical and angiographic follow-up of intracranial aneurysms treated with the Low-Profile Visualized Intraluminal Support Junior (LVIS Jr.) stent and parent vessels of diameter equal to or less than 2.5 mm. Materials and methods We included all patients treated with the LVIS Jr. stent in aneurysms with small parent vessel diameter between March 2015 and July 2017. Periprocedural adverse events, immediate aneurysm occlusion rates, and clinical and angiographic follow-up are reported. Results A total of 35 patients with 35 aneurysms were included. Ten aneurysms were ruptured (28.6%) and 25 were unruptured (71.4%). The parent arteries measured 0.9 mm to 2.5 mm in diameter (mean, 2.2 mm). Intra-procedural thromboembolic complications occurred in four patients (11.4%) and there was an intraoperative aneurysm rupture in one patient (2.8%). Immediate complete aneurysm occlusion was noted in 21 out of 35 patients (60%). Clinical follow-up ranged between one and 25 months (mean, 10.5 months) and magnetic resonance angiography follow-up ranged between four and 24 months (mean, 10.4 months). Complete aneurysm occlusion was achieved in 21 out of 29 patients (72.4%) at last angiographic follow-up (mean, 9.4 months; range four to 23 months). In-stent stenosis occurred in one out of 29 patients (3.4%), who was asymptomatic. Of the four patients with in-stent thrombosis, three patients were treated with "Y configuration" (two patients with middle cerebral artery aneurysms and one patient with an anterior communicating artery aneurysm). Mortality rate was 0%. Neurological morbidity was 2.9%. Conclusions Stenting with the LVIS Jr. stent allowed us to treat complex intracranial aneurysms with parent vessel diameter of 2.5 mm or less with an acceptable safety profile. PMID- 29463146 TI - Optimizing the first-line fertility treatment. AB - The objective of this study was to identify sperm score thresholds to achieve satisfactory intrauterine insemination (IUI) success rates according to the response to stimulation with clomiphene citrate (CC). To minimize the confounding effect of female age, we included only CC/IUI cycles of women <=35 years old. A total of 1,194 CC/IUI cycles were included. Semen volume, concentration, and motility influenced the clinical pregnancy rate (CPR). Normal morphology (>=4%) was associated with a comparable CPR with 3%, 2%, and 1% normal forms (15.6%, 16.1%, 18.1%, and 13.1%, respectively). A combination of the total number of motile spermatozoa in the ejaculate before semen preparation (TM) at a threshold >=20 * 106 was associated with a CPR of 17.8% compared to 4.6% for a threshold <20 * 106 (p < .001). Interestingly, the TM threshold to achieve satisfactory outcomes was lower (10 * 106) in patients who had an optimal response to CC (>=2 dominant follicles with an endometrial thickness >=7 mm) compared to 40 * 106 for those who had a suboptimal response (one dominant follicle with an endometrial thickness <7 mm). In conclusion, the response to superovulation with CC determines each patient's TM threshold required for satisfactory outcomes. Couples whose TM is below the threshold may benefit from a superovulation with gonadotropins or in vitro fertilization. PMID- 29463147 TI - Comparison of hepatitis B virus core-related antigen and hepatitis B surface antigen for predicting HBeAg seroconversion in chronic hepatitis B patients with pegylated interferon therapy. AB - AIM: Recent studies revealed that both quantitative hepatitis B surface antigen (qHBsAg) and hepatitis B core-related antigen (qHBcrAg) could serve as a good marker for predicting treatment response and indirectly reflecting intrahepatic cccDNA levels. This study aimed to compare the value of qHBsAg and qHBcrAg in predicting HBeAg seroconversion among patients undergoing PEG-IFN therapy. METHODS: A total of 31 HBeAg-positive patients, who underwent PEG-IFN therapy for 12 months and follow-up for six months were retrospectively included in this study. The serum qHBsAg level was measured using Elecsys(r) HBsAg II Quant Assay and serum qHBcrAg level was measured using chemiluminescence enzyme immunoassay. RESULTS: During the 12-month treatment, the absolute levels of serum qHBsAg and qHBcrAg were both lower in patients with HBeAg seroconversion as compared to patients without HBeAg seroconversion, but only the difference in qHBcrAg was significant. During the 6-month follow-up period, both qHBsAg and qHBcrAg levels were rebounded significantly among patients without HBeAg seroconversion. Among patients with HBeAg seroconversion, no sustained significant decline of qHBsAg was observed, but serum qHBcrAg levels continued to decline significantly. The ROC curves analysis showed that both absolute qHBcrAg level and the extent of qHBcrAg decline at month 1 had better performance for the prediction of HBeAg seroconversion at month 6 after treatment, as compared to that of qHBsAg. CONCLUSION: Early on-treatment qHBcrAg may be a good biomarker for predicting off treatment HBeAg seroconversion in patients receiving PEG-IFN therapy. PMID- 29463148 TI - Overactive bladder syndrome treatment with ospemifene in menopausal patients with vulvovaginal atrophy: improvement of sexuality? AB - The aim of this study was to assess the effectiveness of ospemifene in the improvement of sexual function in postmenopausal women with vulvovaginal atrophy (VVA) affected by overactive bladder syndrome (OAB) or urge urinary incontinence (UUI). One hundred five postmenopausal patients with VVA affected by OAB and/or UUI were enrolled for the study. All patients received ospemifene 60 mg for 12 weeks. Clinical examination, 3-d voiding diary and the vaginal health index (VHI) were performed at baseline and at 12 weeks. Patients completed the OAB-Q SF, FSFI, FSDS, and SF-36 questionnaires. The patient's satisfaction was also calculated. After 12 weeks, the reduction of urinary symptoms was observed. The OAB-Q symptoms, OAB-Q (HRQL) score were (55.34 +/- 13.54 vs. 23.22 +/- 9.76; p < .0001) and (22.45 +/- 9.78 vs. 70.56 +/- 15.49; p < .0001), before and after treatment. SF-36 questionnaire showed a significant improvement (p < .0001). VHI score increased and the women who regularly practice sexual activity increased after treatment. The total FSFI score increased significantly and the FSDS score changed after 12 weeks (p < .0001). The PGI-I after 12 weeks showed a total success rate of 90.5%. Ospemifene is an effective potential therapy for postmenopausal women with VVA affected by OAB or UUI improving sexual function and quality of life. PMID- 29463149 TI - Transition from Hybrid Capture 2 to Cobas 4800 in Hpv detection: sensitivity and specificity for Cin2+ in two time periods. AB - BACKGROUND: High-risk (HR) Human Papilloma Virus (HPV) Tests for HPV detection differ in sensitivity and specificity. In this study, we evaluated the sensitivity and specificity of the HC2 HR HPV Test and the Cobas 4800 HPV Test in consecutive cervical samples collected from a referral population with a high prevalence of disease, using CIN2+ histology as clinical outcome. METHODS: Ten thousand two-hundred and thirteen consecutive cervical samples were assayed for HR-HPV in the Laboratory Medicine Division of IEO: 5140 from January 2012 to June 2013 with HC2 and 5073 from July 2013 to December 2014 with the Cobas HPV Test. These two assays differ in terms of target genes and testing methods. RESULTS: The test positivity rates for HC2 and Cobas 4800 were 29.5% (1515/5135, 95% CI 28.3-30.8%) and 23.9% (1212/5069, 95% CI 22.7-25.1%), respectively. The detection rates of CIN2+ in the two time periods were 2.8% (145/5140, 95% CI 2.4-3.3%) and 1.6% (79/5073, 95% CI 1.2-1.9%), respectively. The sensitivity for CIN2+ for HC2 and Cobas 4800 was 95.2% (138/145, 95% CI 91.7-98.7%) and 93.7% (74/79, 95% CI 88.3-99.0%), respectively. The specificity for CIN2+ for HC2 and Cobas 4800 was 72.4% (3613/4990, 95% CI 71.2-73.6%) and 77.2% (3852/4990, 95% CI 76.0-78.4%), respectively. There were 23 cases of cancer in each of the two time periods. HC2 detected 100% (23/23). Cobas 4800 detected 82.6% (19/23). CONCLUSIONS: The detection rate of CIN2+ was higher in the first period than in the second period. There was no significant difference in sensitivity of HC2 and Cobas 4800 in women with CIN2+. The specificity of CIN2+ using Cobas 4800 in the second period was higher than HC2 in the first period, probably due to the lower prevalence of CIN2+ in the second period. PMID- 29463150 TI - A noninferiority confirmatory trial of prasugrel versus clopidogrel in Japanese patients with non-cardioembolic stroke: rationale and study design for a randomized controlled trial - PRASTRO-I trial. AB - BACKGROUND: This comparison of PRAsugrel and clopidogrel in Japanese patients with ischemic STROke (PRASTRO)-I trial investigates the noninferiority of prasugrel to clopidogrel sulfate in the prevention of recurrence of primary events (ischemic stroke, myocardial infarction, and death from other vascular causes), and the long-term safety of prasugrel in Japanese patients with non cardioembolic stroke. RESEARCH DESIGN AND METHODS: This was an active-controlled, randomized, double-blind, double-dummy, parallel-group study conducted between July 2011 and March 2016 at multiple centers around Japan. Patients had to meet eligibility criteria before receiving 3.75 mg prasugrel or 75 mg clopidogrel orally once daily for a period of 96-104 weeks. RESULTS: A total of 3747 patients were included in this trial; 1598 in the 3.75 mg prasugrel group and 1551 in the 75 mg clopidogrel group completed the study. During the study period, 287 (15.2%) patients in the prasugrel group and 311 (16.7%) in the clopidogrel group discontinued treatment. Baseline characteristics, safety, and efficacy results are forthcoming and will be published separately. CONCLUSIONS: This article presents the study design and rationale for a trial investigating the noninferiority of prasugrel to clopidogrel sulfate with regards to the inhibitory effect on primary events in patients with non-cardioembolic stroke. PMID- 29463151 TI - The role of FTO variants in the susceptibility of polycystic ovary syndrome and in vitro fertilization outcomes in Chinese women. AB - We investigated the association between single nucleotide polymorphisms (SNPs) in the fat mass and obesity associated (FTO) gene (rs9926289 A/G, rs79206939 A/G, rs9930506 A/G, rs8050136 A/C, and rs1588413 C/T) and polycystic ovary syndrome (PCOS), as well as outcomes of in vitro fertilization (IVF). A case-control study consisting of 147 PCOS patients and 120 healthy controls was conducted. FTO SNPs were genotyped by PCR to determine allelic frequencies, and IVF outcomes were analyzed. The results showed that FTO rs8050136 (p = .025) and rs1588413 (p = .042) were significantly associated with PCOS susceptibility, and women with risk alleles were often found to be obese (p < .05). For SNP rs8050136, women with AA + AC genotypes had higher body mass indexes (BMIs), oral glucose tolerance test/2 h (OGTT) levels and implantation rates but lower follicle-stimulating hormone (FSH) and human chorionic gonadotropin (hCG) day progesterone levels and ovulation numbers (all p < .05) than those with the CC genotype. For SNP rs1588413, women carrying risk alleles exhibited higher BMIs, implantation rate, and levels of luteinizing hormone (LH), estradiol, and OGTT/2 h (all p < .05) compared with those with non-risk genotypes. Therefore, these findings suggest that rs8050136 and rs1588413 are associated with PCOS susceptibility, and that women with risk alleles have less ovulation numbers but higher implantation rates than those with other genotypes. PMID- 29463152 TI - The influence of thyroid autoimmunity on embryo quality in women undergoing assisted reproductive technology. AB - The influence of thyroid autoimmunity in assisted reproductive technology (ART) outcome in euthyroid women is still controversial. In this study, we retrospectively evaluated embryo quality in 123 euthyroid women undergoing ART with or without thyroid autoantibodies (TAA). Embryo quality was assessed in 119 embryos of 29 infertile patients with TAA and in 394 embryos of 94 infertile patients without TAA. Our results showed not statistically significant differences in age, body mass index, anti-Mullerian hormone, follicle stimulating hormone, free triiodothyronine, and free thyroxine levels between cases and controls. Thyroid stimulating hormone was within the normal range, but significantly higher in TAA patients compared with the controls (2.4 +/- 0.8 vs. 2 +/- 0.9 mIU/L, respectively, p < .01). The number of oocytes picked up and fertilized was comparable between the two groups. Embryo quality was significantly impaired in women with at least one autoantibody (p < .001). Implantation rate, pregnancy rate, and ongoing pregnancy rate were comparable in the two groups. These results suggest a negative impact of thyroid autoimmunity in embryo quality in women undergoing ART even when thyroid function is normal. PMID- 29463153 TI - Suspected adverse drug reaction reports with oral anticoagulants in Portugal: a pharmacovigilance study. AB - OBJECTIVE: In this pharmacovigilance study, we aimed to determine the incidence of spontaneously reported suspected adverse drug reactions (ADRs) related to oral anticoagulants: non-vitamin K antagonist oral anticoagulants (NOACs; apixaban, dabigatran, edoxaban, rivaroxaban) and vitamin K antagonists (VKA) Research design and methods: In this retrospective observational study, we extracted all the individual case safety reports related to oral anticoagulants recorded in the Portuguese Pharmacovigilance Database (January 2010 to April 2015). The annual incidence of suspected ADRs was estimated using drug exposure data. Disproportionality of reporting ADR was addressed through reporting odds ratio (ROR) and 99% confidence intervals. RESULTS: We appraised 794 suspected ADR (78% related to NOACs). The annual number of ADRs increased overtime with 9 ADRs/million Defined Daily Dose (DDD) at the end of 2014. The incidence of NOACs ADRs decreased from 2012 onwards. VKA showed a disproportion in 'Investigation' (ROR 0.10, 99%CI 0.05-0.22) and 'Injury, poisoning and procedural complications' (ROR 0.36, 99%CI 0.19-0.69) ADRs compared with NOACs. NOACs had a higher significant disproportion of 'Nervous system disorders' related ADRs (ROR 3.98, 99%CI 1.50-10.53). CONCLUSIONS: Reporting of ADRs associated with oral anticoagulants (mainly NOACs), is increasing. Exploratory disproportion analyses showed an increase of reports of nervous system ADRs with NOACs, and INR-related ADRs with VKA. PMID- 29463154 TI - Evaluation of changes in biochemical composition of fetal brain between 18th and 40th gestational week in proton magnetic resonance spectroscopy. AB - INTRODUCTION: The aim of this study is to determine the right 1H MRS spectra of the brain in fetuses of different age, and then to define what metabolic changes occur between 18th and 40th weeks of pregnancy. METHODS: 1H MRS studies of 32 fetuses aged 18-40 gestational weeks were performed, in which the MRI excluded central nervous system malformations. The studied group included 11 fetuses aged 18-25 weeks (the second half of the second trimester), 14 fetuses aged 26-33 weeks (the first half of the third trimester), and seven fetuses aged 34-40 weeks (the second half of the third trimester). The relative ratios of metabolites concentrations to the sum of all metabolites were calculated. RESULTS: Increase in the concentrations of N-acetylaspartate (NAA), Cr, Cho, and myo-inositol (mI) with gestational age is statistically significant. Only increase in Glx is statistically insignificant. In the analyzed period of pregnancy also, an insignificant increase of NAA/Sigma and Cr/Sigma ratios and a decrease of mI/Sigma, Cho/Sigma and Glx/Sigma ratios were noticed. CONCLUSIONS: Changes in the 1H MRS spectrum are visible with increasing age of the fetus. All studied substances in fetal brain change their concentrations during pregnancy, which may be associated with the synaptic and dendritic development as well as myelination. Knowledge about the chemical changes in the fetal brain can provide valuable information in studies of the mechanisms of pregnancy and fetal development, define steps of brain metabolic development and explain reasons of pathologies.

AB - The initiation and progression of hepatocellular carcinoma (HCC) is a multistage process involving a variety of changes at the gene level. Methylation of insulin like growth factor-binding protein 7 (IGFBP7) plays a crucial role in HCC development. The main purpose of this study was to investigate the relationship between oxidative stress, DNA methyltransferases (DNMTs) expression, and IGFBP7 methylation, and to evaluate the prognostic value of serum IGFBP7 methylation status in patients with HCC after hepatectomy. We enrolled 155 patients with HCC undergoing surgical resection. The IGFBP7 methylation status, DNMTs mRNA levels and malondialdehyde (MDA), xanthine oxidase (XOD), reduced glutathione hormone (GSH), and glutathione-S-transferases (GST) levels were detected. MDA and XOD levels were significantly higher in IGFBP7 methylated group than unmethylated group, while GSH level was lower in methylated group than unmethylated group. The DNMT1 and DNMT3a mRNA levels were higher in IGFBP7 methylated group than unmethylated group. Kaplan-Meier curve analysis revealed that IGFBP7 promoter methylation was significantly correlated with overall survival (OS) (p < .001). Moreover, IGFBP7 methylation was an independent prognostic predictor for OS (p = .000) and early tumour recurrence (ETR) (p = .008) in HCC after hepatectomy. Our results indicated that IGFBP7 promoter methylation was associated with oxidative stress and DNMTs expression. Meanwhile, IGFBP7 promoter methylation was associated with OS and ETR, indicating that it might serve as a potentially independent prognostic factor in patients with HCC after hepatectomy.

AB - PURPOSE: We aimed to investigate the association of vitamin D receptor (VDR) gene TaqI single nucleotide polymorphism (SNPs) with serum lead (Pb) levels in maternal and umbilical cord blood. MATERIALS AND METHODS: Eighty-one patients who lived in Konya, Turkey for the last 3 years and had delivery at Baskent University Konya Hospital in 2016 were included in this study. Venous blood samples were drawn from each volunteer immediately before giving birth to determine the maternal Pb levels and VDR SNPs. Additionally, umbilical cord blood samples were collected from the umbilical vein into tube with EDTA as an anticoagulant immediately after birth to determine Pb levels of the fetus. RESULTS: The median level of Pb in the maternal blood was 29.00 (Interquartile Range (IQR) = 16.35) MUg/L and the median Pb level in the cord blood was 22.50 (IQR = 9.75) MUg/L. Blood Pb level of women living in the urban area was significantly higher than in those living in the rural area (Z = 2.118; p = .034). There was a very strong positive correlation between the Pb levels in the maternal blood and in the umbilical cord blood (rho = 0.825, p < .001, respectively). Regarding VDR SNPs, "TT", "TC", and "CC" VDR TaqI genotypes were observed in 28 (34.6%), 45 (55.5%), and eight samples (9.9%), respectively. Pb levels in maternal and cord blood were higher in women with the "CC" VDR TaqI genotype; however, there was no statistically significant difference (p > .05). CONCLUSIONS: Although women with the "CC" VDR TaqI genotype had higher maternal and cord blood Pb levels, this was statistically insignificant and therefore, VDR TaqI SNPs did not significantly affect maternal and umbilical cord blood Pb levels. PMID- 29463157 TI - Comparing Recalibration Strategies for Electroencephalography-Based Decoders of Movement Intention in Neurological Patients with Motor Disability. AB - Motor rehabilitation based on the association of electroencephalographic (EEG) activity and proprioceptive feedback has been demonstrated as a feasible therapy for patients with paralysis. To promote long-lasting motor recovery, these interventions have to be carried out across several weeks or even months. The success of these therapies partly relies on the performance of the system decoding movement intentions, which normally has to be recalibrated to deal with the nonstationarities of the cortical activity. Minimizing the recalibration times is important to reduce the setup preparation and maximize the effective therapy time. To date, a systematic analysis of the effect of recalibration strategies in EEG-driven interfaces for motor rehabilitation has not yet been performed. Data from patients with stroke (4 patients, 8 sessions) and spinal cord injury (SCI) (4 patients, 5 sessions) undergoing two different paradigms (self-paced and cue-guided, respectively) are used to study the performance of the EEG-based classification of motor intentions. Four calibration schemes are compared, considering different combinations of training datasets from previous and/or the validated session. The results show significant differences in classifier performances in terms of the true and false positives (TPs) and (FPs). Combining training data from previous sessions with data from the validation session provides the best compromise between the amount of data needed for calibration and the classifier performance. With this scheme, the average true (false) positive rates obtained are 85.3% (17.3%) and 72.9% (30.3%) for the self paced and the cue-guided protocols, respectively. These results suggest that the use of optimal recalibration schemes for EEG-based classifiers of motor intentions leads to enhanced performances of these technologies, while not requiring long calibration phases prior to starting the intervention. PMID- 29463158 TI - The nature, magnitude, and reporting compliance of device-related events for intravenous patient-controlled analgesia in the FDA Manufacturer and User Facility Device Experience (MAUDE) database. AB - BACKGROUND: The aim of this study is to determine the characteristics, magnitude, and the quality of reporting of mandated events involving intravenous patient controlled analgesia (IV-PCA) devices in the Food and Drug Administration (FDA) Manufacturer and User Facility Device Experience (MAUDE) database; a postmarket surveillance system. METHODS: We utilized a mixed-methods approach to systematically characterize structured data and text narratives associated with IV-PCA events submitted to MAUDE between 1 January 2011 and 12 September 2016. RESULTS: Of 1,430 IV-PCA events reported during the study period, 6.4% were adverse events (AEs) as identified via structured data fields in the MEDWATCH forms. Upon qualitative review of the narrative texts, 11.0% of events were associated with an unfavorable clinical outcome, which was 71% higher than the incidence of the adverse outcomes reported using the structured data fields. Device-related issues, which were mostly preventable, accounted for 86.9% of events. Of 65 reportable events submitted by manufacturers, 18.5% did not comply with reporting requirements as mandated by law. CONCLUSION: Patients on IV-PCA continue to experience serious complications as a result of preventable errors. Multi-modal interventions including educational training and the development and adoption of PCA devices with improved safety features are needed to improve safety. PMID- 29463159 TI - Prophylactically applied Hydrofilm polyurethane film dressings reduce radiation dermatitis in adjuvant radiation therapy of breast cancer patients. AB - PURPOSE: Radiation-induced skin injury represents one of the most common side effects in breast cancer patients receiving adjuvant whole-breast radiotherapy. Numerous systemic and topical treatments have been studied in the prevention and management of radiation-induced skin injury without providing sustainable treatment strategies. While superficial barrier-forming skin products such as dressings are the standard of care in wound care management, their utilization as preventive treatment approach in radiotherapy has barely attracted attention. METHODS: In this prospective, intra-patient randomized study, Hydrofilm polyurethane film dressings were applied prophylactically to either the medial or lateral breast half of 62 patients with breast cancer undergoing adjuvant radiation therapy following breast conserving surgery. The breast half contralateral to the film dressing was concurrently treated with 5% urea lotion as control skin care. Maximum severity of radiation dermatitis was assessed using RTOG/EORTC toxicity scores, photospectrometric erythema measurements and patient assessed modified RISRAS scale. RESULTS: In the Hydrofilm compartments, mean maximum RTOG/EORTC radiation dermatitis severity grades were significantly reduced from 1.33 to 0.35 and photospectrometric measurements showed significantly reduced erythema severity, as compared to the control compartments, with an overall response rate of 89.3%. Hydrofilm completely prevented moist desquamation and significantly reduced patients' subjective experience of itching and pain. CONCLUSION: The obtained results along with a favorable cost-benefit ratio and an easy and quick application suggest a prophylactic application of Hydrofilm in adjuvant radiotherapy of breast cancer patients to reduce or even prevent radiation dermatitis. PMID- 29463160 TI - Candidate SNP of CACNA2D1 Gene Associated with Clinical Mastitis and Production Traits in Sahiwal (Bos taurus indicus) and Karan Fries (Bos taurus taurus * Bos taurus indicus). AB - The present study was conducted to identify polymorphisms in CACNA2D1 gene and their association with clinical mastitis and production traits. Exon 18 and its flanking regions were screened for the presence of SNPs. Statistical analysis was performed to identify association of period of birth, breed, and genotype with mastitis incidence on randomly selected 103 Sahiwal and 102 Karan Fries cattle. PCR-RFLP analysis revealed that g.38819398G > A mutation in exon 18 (269 bp amplicon) of CACNA2D1 gene resolved into AA, AG, and GG genotypes in Sahiwal and Karan Fries cattle. Wald chi-square analysis revealed that the period of birth, breed, and genotype were significantly associated with mastitis incidence. GG genotyped cattle were found to be less susceptible to mastitis. Least square analysis revealed that GG and AG genotype animals of G38819398A SNP of CACNA2D1 gene in Sahiwal as well as in Karan Fries cattle were associated with higher average milk yields during 1st, 2nd, and 3rd lactations (P < 0.01). These observations and their differential association with the incidence of mastitis and production traits can be utilized as an aid to selection for simultaneous improvement of both antagonistic traits; however, validation of results on large number of animals is warranted. PMID- 29463161 TI - Should information about sexual health be included in education directed toward men with cardiovascular diseases? AB - BACKGROUND: Modifiable risk factors contribute to the pathogenesis of cardiovascular disease (CVD) and erectile dysfunction (ED). We aimed to compare the knowledge about the contribution of modifiable risk factors to the pathogenesis of CVD and ED. The impact of patients' having modifiable risk factors on the awareness of their negative influence on the development of CVD and ED was examined. METHODS: To this multicenter cohort study, we included 417 patients with CHD who had been hospitalized in the cardiology or cardiac surgery department during the previous six weeks and underwent cardiac rehabilitation in one of the five centers. Knowledge about modifiable risk factors was collected. ED was assessed by an abridged IIEF-5 questionnaire. Comparisons between groups were conducted using the Student's t-test, Mann-Whitney U test, and Kruskal Wallis test. Relationships were analyzed with Spearman's rank correlation coefficient. RESULTS: The mean number of correctly identified risk factors for CVD was significantly higher than those for ED (3.71 +/- 1.87 vs. 2.00 +/- 1.94; p < .0001). Smoking was the most recognized risk factor both for CVD and ED. Dyslipidemia was least frequently identified as a risk factor for CVD. Sedentary lifestyle was the only risk factor whose incidence did not affect the level of patient knowledge. CONCLUSIONS: Cardiac patients with ED know more about risk factors for CVD than ED. It is necessary to include information about the negative impact of modifiable risk factors on sexual health into education programs promoting healthy lifestyles in men with cardiovascular diseases. PMID- 29463162 TI - Comparative in vivo evaluation of novel formulations based on alginate and silver nanoparticles for wound treatments. AB - In the present study, possibilities for using novel nanocomposites based on alginate and silver nanoparticles for wound treatment were investigated in a second-degree thermal burn model in Wistar rats. Silver nanoparticles (AgNPs) were electrochemically synthesized in alginate solutions that were further utilized to obtain the Ag/alginate solution and microfibers for subsequent in vivo studies. Daily applications of the Ag/alginate colloid solution, containing AgNPs, alginate and ascorbic acid (G3), wet Ag/alginate microfibers containing AgNPs (G5) and dry Ag/alginate microfibers containing AgNPs (G6) were compared to treatments with a commercial cream containing silver sulfadiazine (G2) and a commercial Ca-alginate wound dressing containing silver ions (G4), as well as to the untreated controls (G1). Results of the in vivo study have shown faster healing in treated wounds, which completely healed on day 19 (G4, G5 and G6) and 21 (G2 and G3) after the thermal injury, while the period for complete reepitelization of untreated wounds (G1) was 25 days. The macroscopic analysis has shown that scabs fell off between day 10 and 12 after the thermal injury induction in treated groups, whereas between day 15 and 16 in the control group. These macroscopic findings were supported by the results of histopathological analyses, which have shown enhanced granulation and reepithelization, reduced inflammation and improved organization of the extracellular matrix in treated groups without adverse effects. Among the treated groups, dressings based on Ca alginate (G4-G6) induced enhanced healing as compared to the other two groups (G2, G3), which could be attributed to additional stimuli of released Ca2+. The obtained results indicated potentials of novel nanocomposites based on alginate and AgNPs for therapeutic applications in wound treatments. PMID- 29463163 TI - Staff Perceptions of Adult Day Centers Providing Post-Acute Care for Persons With Dementia. AB - The purpose of this study was to examine the perception of adult day services (ADS) staff and hospital discharge planners regarding the feasibility of ADS to provide post-acute care (PAC) for persons with dementia. We conducted key informant interviews with emergency department (ED) and inpatient hospital discharge planners ( n = 9), and two focus groups with ADS staff ( n = 15) representing five ADS programs. Four thematic categories were identified from the discharge planners, including concerns for patients, factors influencing discharge, experience with ADS, and conditions for ADS referrals. Four categories identified from ADS staff interviews include public lack of knowledge of ADS, communication challenges, ADS to prevent hospitalization and ED visits, and barriers to providing PAC. Lack of knowledge about ADS, the role of family in PAC decisions, and the lack of reimbursement for PAC in ADS were identified as the most significant drivers in the ability of ADS to provide PAC. PMID- 29463165 TI - Results of 14 years of brachytherapy for localized prostate cancer in Denmark: the Herlev cohort. AB - OBJECTIVE: Brachytherapy is one of several curative treatments for localized prostate cancer (PCa). The objective of this study was to report biochemical recurrence-free survival (BRFS), metastatic-free survival (MFS) and PCa-specific mortality after low-dose brachytherapy, stratified according to the D'Amico risk classification in a large Danish cohort. MATERIALS AND METHODS: The study population comprised 502 men treated with brachytherapy in 1998-2012. BRFS was defined by the Phoenix criteria. Kaplan-Meier survival analysis was used to estimate BRFS and MFS. The cumulative PCa mortality was analysed using competing risk analyses. Multivariable Cox regression analysis was used to estimate risk of biochemical recurrence. RESULTS: In total, 206 men were classified with low-risk PCa, 265 men with intermediate-risk PCa and 33 men with high-risk PCa. Median follow-up was 6.6 years [95% confidence interval (CI) 6.2-7.0]. The 10 year BRFS was 90% (95% CI 83-97), 75% (95% CI 65-87) and 75% (95% CI 59-92) in men with low , intermediate- and high-risk PCa, respectively. The 10 year MFS was 95% (95% CI 89-100), 93% (95% CI 88-98) and 78% (95% CI 57-99) in men with low-, intermediate and high-risk PCa, respectively. The 10 year cumulative incidence of PCa mortality was 1% (95% CI 0-3), 5% (95% CI 0-12) and 11% (95% CI 0-25) for men with low-, intermediate- and high-risk PCa, respectively. CONCLUSIONS: Low-dose brachytherapy offers good short- to intermediate-term cancer control in selected men with localized PCa. Further studies are needed for safety analyses and for comparison with other treatment modalities. PMID- 29463164 TI - Apolipoprotein E epsilon4 Genotype Is Associated with Elevated Psychiatric Distress in Veterans with a History of Mild to Moderate Traumatic Brain Injury. AB - As few studies have examined the relationship between the apolipoprotein E (APOE) gene and clinical outcomes after military-related traumatic brain injury (TBI), we aimed to determine whether the epsilon4 allele of the APOE gene influences neuropsychiatric symptoms in veterans with a history of mild-to-moderate TBI. Participants included 133 veterans (TBI = 79; military controls [MC] = 54) who underwent APOE genotyping and were divided into epsilon4+ (TBI = 18; MC = 15) and epsilon4- (TBI = 61; MC = 39) groups. All participants underwent evaluation of psychological distress using the Beck Depression Inventory-II, Beck Anxiety Inventory, and PTSD Checklist-Military Version. Two-way analyses of variance were conducted to examine the effect of group (TBI vs. MC) and APOE-epsilon4 status (epsilon4+ vs. epsilon4-) across symptom measures. There was a significant main effect of group across all symptom measures (TBI > MC; all p values <0.001), no main effect of epsilon4 genotype (p = 0.152-0.222), and a significant interaction of group by epsilon4 genotype across all measures (p = 0.027-0.047). Specifically, for TBI participants, epsilon4+ veterans demonstrated significantly higher symptom scores across all measures when compared to epsilon4- veterans (p = 0.007-0.015). For MC participants, epsilon4 status had no effect on the severity of psychiatric symptom scores (p = 0.585-0.708). Our results demonstrate that, in our well-characterized sample of veterans with history of neurotrauma, possession of the epsilon4 allele conveys risk for increased symptomatology (i.e., depression, anxiety, and post-traumatic stress disorder), even well outside of the acute phase of injury. Findings suggest a meaningful relationship between APOE genotype and psychiatric distress post-TBI, and they suggest that there is a brain basis for the complex neuropsychiatric presentation often observed in this vulnerable population. Future longitudinal studies are needed in order to further our understanding of how genetic factors influence response to TBI. PMID- 29463166 TI - Clinicopathological indicators of survival among patients with pulmonary carcinoid tumor. AB - BACKGROUND: Pulmonary carcinoids (PC) are rare malignant neoplasms that cover approximately 1% of all lung cancers. PCs are classified by histological criteria as either typical (TC) or atypical (AC). Histological subtype is the most studied prognostic factor. The aim of this study was to evaluate if other tissue or clinical features are associated with patient outcomes. MATERIAL AND METHODS: We retrospectively reviewed clinical records of 133 PC patients who underwent operation in the Helsinki University Hospital between 1990 and 2013. Tissue specimens were re-evaluated, processed into tissue microarray format and stained immunohistochemically with serotonin, calcitonin, adrenocorticotropic hormone (ACTH), thyroid transcription factor-1 (TTF-1) and Ki-67. Survival and risk analyses were performed. RESULTS: Based on histology, 75% (n = 100) of the tumors were TCs and 25% (n = 33) ACs. TCs had higher 10-year disease-specific survival (DSS) rate than ACs (99% (95% CI, 93-100%) for TCs vs. 82% (95% CI, 61-92%) for ACs). Hormonally active tumors expressing serotonin, calcitonin or ACTH were noted in 53% of the specimens but hormonal expression was not associated with DSS. TTF-1 was positive in 78% of the specimens but was not associated with DSS. Ki-67 index varied between <1% and 15%. Ki-67 >= 2.5% was associated with shorter DSS (p = .004). The presence of metastatic disease (p = .001), tumor size >=30 mm (p = .021) and atypical histology (p = .011) were also associated with disease specific mortality. CONCLUSIONS: We conclude that PCs are uncommon tumors. When resected, the long-term survival is in general favorable. In this consecutive, single-institution cohort of patients, presence of metastatic disease, tumor size, histological subtype and Ki-67 index were associated with shorter disease specific survival. As TC and AC have different clinical behaviors, the correct tumor classification at the time of diagnosis is a necessity. PMID- 29463167 TI - Conducting neuropsychological assessment with transgender individuals. AB - OBJECTIVE: The purpose of this paper is to provide an overview of helpful clinical practices when working with transgender adult individuals. METHOD: While the number of openly transgender individuals appears to be growing with society's increased acceptance and awareness, many neuropsychologists have had few opportunities to gain experience with this patient population. In this article, we review the existing literature as it relates to clinical neuropsychological practice. RESULTS: We describe important terminology, ideals for creating an environment of respect, and how existing clinical guidelines for transgender individuals may apply to neuropsychology. In addition, we review the primary steps in the assessment process and provide a set of principles and recommendations for conducting neuropsychological assessments with transgender patients. CONCLUSIONS: There is a paucity of guidance in the field for working with transgender individuals. This article represents a step forward in the dialog and we look forward to future research that develops appropriate normative information, increases understanding of psychosocial factors, and better appreciates the range of hormonal influences for transgender individuals. PMID- 29463168 TI - Associated Mortality of Liberal Fluid Administration in Sepsis. AB - Fluid resuscitation, to restore intravascular volume and improve oxygen delivery, is a crucial step in early resuscitation efforts of patients with sepsis or septic shock. The 2016 Surviving Sepsis Campaign guidelines suggest the use of dynamic versus static measures of fluid responsiveness and fluid resuscitation with at least 30 mL/kg of intravenous crystalloid within the first 3 hours followed by fluid administration if hemodynamic factors continue to improve. Despite these recommendations, risks to this practice may exist as multiple studies have demonstrated an association between a positive fluid balance and/or administration of large fluid volume and increase in mortality. These studies are limited by variations in their methodologic design; therefore, cause and effect cannot yet be determined. Future multicenter, randomized, controlled studies that evaluate fluid balance and fluid volume need to be conducted to clarify the role of fluid administration to patients with sepsis to maximize benefits and minimize risk. PMID- 29463169 TI - Clinical Outcomes of Student Pharmacist-Driven Medication Histories at an Academic Medical Center. AB - BACKGROUND: Many studies have shown the positive impact that student pharmacists have on patients' health; however, no studies have been published evaluating student pharmacists' impact on direct patient outcomes (ie, readmission, emergency department [ED] visits, length of stay) related to the medication history process. OBJECTIVE: To evaluate the impact of student pharmacist-obtained medication histories on identification of medication discrepancies and clinical outcomes. METHODS: Student pharmacists obtained medication histories and then compared the history to that obtained by other health-care providers. Students documented discrepancies and interventions were completed. Control patients were identified and discharge medication list and 30-day readmissions were compared. RESULTS: Seventeen students conducted 215 patient interviews, and 1848 modifications were made to documented home medications in the electronic medical record. Compared to controls (n = 148 student pharmacist, 149 controls), a nonsignificant improvement was found in discharge medication list completeness scores in patients seen by student pharmacists (3.94 vs 3.63; P = .06); but no difference was found in accuracy scores (0.92 vs 0.93; P = .41). Fewer ED visits at 30 days were found in the student pharmacist group (8 vs 18; P = .045), with no difference in readmissions. CONCLUSIONS: Student pharmacist-obtained medication histories improved the information available for identifying drug related problems for inpatients, completeness of the discharge medication list, and ED visits within 30 days. PMID- 29463170 TI - Electronic Transport in Two-Dimensional Materials. AB - Two-dimensional (2D) materials have captured the attention of the scientific community due to the wide range of unique properties at nanometer-scale thicknesses. While significant exploratory research in 2D materials has been achieved, the understanding of 2D electronic transport and carrier dynamics remains in a nascent stage. Furthermore, because prior review articles have provided general overviews of 2D materials or specifically focused on charge transport in graphene, here we instead highlight charge transport mechanisms in post-graphene 2D materials, with particular emphasis on transition metal dichalcogenides and black phosphorus. For these systems, we delineate the intricacies of electronic transport, including band structure control with thickness and external fields, valley polarization, scattering mechanisms, electrical contacts, and doping. In addition, electronic interactions between 2D materials are considered in the form of van der Waals heterojunctions and composite films. This review concludes with a perspective on the most promising future directions in this fast-evolving field. PMID- 29463171 TI - Malignant hydrocele: a rare manifestation of peritoneal carcinomatosis of colorectal origin as a transcoelomic spread into the scrotum - case report and literature overview. PMID- 29463172 TI - Radiation-induced G2/M arrest rarely occurred in glioblastoma stem-like cells. AB - PURPOSE: The purpose of this study is to systematically study the cell-cycle alterations of glioblastoma stem-like cells (GSLCs) after irradiation, possibly enriching the mechanisms of radioresistance of GSLCs. MATERIALS AND METHODS: GSLCs were enriched and identified, and then the radioresistance of GSLCs was validated by analyzing cell survival, cell proliferation, and radiation-induced apoptosis. The discrepancy of the cell-cycle distribution and expression of cell cycle-related proteins between GSLCs and glioblastoma differentiated cells (GDCs) after irradiation was completely analyzed. RESULTS: The survival fractions and the cell viabilities of GSLCs were significantly higher than those of GDCs after irradiation. Radiation-induced apoptosis was less prominent in GSLCs than in GDCs. After irradiation with high-dose X-rays, the percentages of GDCs in G2/M phase was evidently increased. However, radiation-induced G2/M arrest occurred less frequently in GSLCs, but S-phase arrest occurred in GSLCs after irradiation with 8 Gy. Further mechanistic studies showed that the expressions levels of Cdc25c, Cdc2, and CyclinB1 in GSLCs were not apparently changed after irradiation, while those of p-ATM and p-Chk1 were sharply increased after irradiation in GSLCs. The basal level of Cdc25c expression in GSLCs was much higher than that in GDCs. CONCLUSIONS: We explored the cell-cycle alterations and cell-cycle-related proteins expression levels in GSLCs after irradiation, providing a novel mechanism of radioresistance of GSLCs.

This article sets out arguments for and against the truth of this assertion. PMID- 29463174 TI - Cumulative use of salivary markers with an adaptive design improves detection of periodontal disease over fixed biomarker thresholds. AB - OBJECTIVE: Aim was to analyze the diagnostic ability of cumulative risk score (CRS), which uses salivary levels of Porphyromonas gingivalis, interleukin (IL) 1beta, and matrix metalloproteinase (MMP)-8 in an adaptive design, compared to previously reported thresholds of each marker alone. MATERIALS AND METHODS: Oral and general health information of 463 participants were included in the analysis. Having the percentage of bleeding on probing (BOP) > 25%, having at least two sites with probing pocket depth (PPD) of 4-5 mm or having at least one tooth with alveolar bone loss (ABL) of at least 1/3 of the root length were accepted as outcome variables. Being above the salivary threshold concentrations of P. gingivalis, IL-1beta, and MMP-8 and CRS values were used as explanatory variables. Receiver operating characteristics (ROC) producing an area under the curve (AUC) and multinomial regression analysis were used in statistical analysis. RESULTS: CRS provided AUCs larger than any other tested biomarker threshold. Sensitivity and specificity of CRS for detecting clinical markers of periodontitis were acceptable, and a strong association was observed between the highest CRS score and having at least two sites with PPD of 4-5 mm. CONCLUSION: CRS brings additional power over fixed thresholds of single biomarkers in detecting periodontitis. PMID- 29463175 TI - Developing a cultural context for conducting a neuropsychological evaluation with a culturally diverse client: the ECLECTIC framework. AB - OBJECTIVE: With the increasing diversification of the American population, the discipline of neuropsychology is challenged to develop appropriate tools and conceptual models to meet its evolving client base. Thus far, the focus has been on developing appropriate tests and norms to obtain accurate testing data. By contrast, far less attention has been paid to the contextual impact of culture on an evaluation. This paper attempts to address this shortcoming. METHODS: This manuscript introduces the ECLECTIC framework for conceptualizing different facets of culture pertinent for understanding a culturally diverse client when conducting a neuropsychological evaluation. Individual components of the framework (E: education and literacy; C: culture and acculturation; L: language; E: economics; C: communication; T: testing situation: comfort and motivation; I: intelligence conceptualization; and C: context of immigration) are introduced and potential biases to fairness in testing are described. In this manner, the framework specifies how individual facets of culture can impact neuropsychological test performance. CONCLUSIONS: Clinical implementation of the framework will be illustrated with a case sample. Strengths and weaknesses of the framework are discussed as well as recommendations for implementation. PMID- 29463176 TI - Neuroinflammation after Traumatic Brain Injury Is Enhanced in Activating Transcription Factor 3 Mutant Mice. AB - Traumatic brain injury (TBI) induces a neuroinflammatory response resulting in astrocyte and microglia activation at the lesion site. This involves upregulation of neuroinflammatory genes, including chemokines and interleukins. However, so far, there is lack of knowledge on transcription factors (TFs) modulating this TBI-associated gene expression response. Herein, we analyzed activating transcription factor 3 (ATF3), a TF encoding a regeneration-associated gene (RAG) predominantly studied in peripheral nervous system (PNS) injury. ATF3 contributes to PNS axon regeneration and was shown before to regulate inflammatory processes in other injury models. In contrast to PNS injury, data on ATF3 in central nervous system (CNS) injury are sparse. We used Atf3 mouse mutants and a closed head weight-drop-based TBI model in adult mice to target the rostrolateral cortex resulting in moderate injury severity. Post-TBI, ATF3 was upregulated already at early time points (i.e,. 1-4 h) post-injury in the brain. Mortality and weight loss upon TBI were slightly elevated in Atf3 mutants. ATF3 deficiency enhanced TBI-induced paresis and hematoma formation, suggesting that ATF3 limits these injury outcomes in wild-type mice. Next, we analyzed TBI-associated RAG and inflammatory gene expression in the cortical impact area. In contrast to the PNS, only some RAGs (Atf3, Timp1, and Sprr1a) were induced by TBI, and, surprisingly, some RAG encoding neuropeptides were downregulated. Notably, we identified ATF3 as TF-regulating proneuroinflammatory gene expression, including CCL and CXCL chemokines (Ccl2, Ccl3, Ccl4, and Cxcl1) and lipocalin. In Atf3 mutant mice, mRNA abundance was further enhanced upon TBI compared to wild-type mice, suggesting immune gene repression by wild-type ATF3. In accord, more immune cells were present in the lesion area of ATF3-deficient mice. Overall, we identified ATF3 as a new TF-mediating TBI-associated CNS inflammatory responses. PMID- 29463177 TI - The combination of targeted and systematic prostate biopsies is the best protocol for the detection of clinically significant prostate cancer. AB - OBJECTIVE: Compared with standard systematic transrectal ultrasound (TRUS)-guided biopsies (SBx), targeted biopsies (TBx) using magnetic resonance imaging (MRI)/TRUS fusion could increase the detection of clinically significant prostate cancer (PCa-s) and reduce non-significant PCa (PCa-ns). This study aimed to compare the performance of the two approaches. MATERIALS AND METHODS: A prospective, single-center study was conducted on all consecutive patients with PCa suspicion who underwent prebiopsy multiparametric MRI (mpMRI) using the Prostate Imaging Reporting and Data System (PI-RADS). All patients underwent mpMRI/TRUS fusion TBx (two to four cores/target) using UroStationTM (Koelis, Grenoble, France) and SBx (10-12 cores) during the same session. PCa-s was defined as a maximal positive core length >=4 mm or Gleason score >=7. RESULTS: The study included 191 patients (at least one suspicious lesion: PI-RADS >=3). PCa was detected in 55.5% (106/191) of the cases. The overall PCa detection rate and the PCa-s detection rate were not significantly higher in TBx alone versus SBx (44.5% vs 46.1%, p = .7, and 38.2% vs 33.5%, p = .2, respectively). Combined TBx and SBx diagnosed significantly more PCa-s than SBx alone (45% vs 33.5%, p = .02). PCa-s was detected only by TBx in 12% of cases (23/191) and only by SBx in 7.3% (14/191). Gleason score was upgraded by TBx in 16.8% (32/191) and by SBx in 13.6% (26/191) of patients (p = .4). CONCLUSIONS: The combination of TBx and SBx achieved the best results for the detection and prognosis of PCa-s. The use of SBx alone would have missed the detection of PCa-s in 12% of patients.

AB - To determine the genetic diversity and validate the pedigree record of Chinese Guanzhong horse, 67 individuals were genotyped with eight microsatellite markers. In our study, the mean observed and expected heterozygosities were 0.51 and 0.66, respectively. The mean observed number of alleles for the Guanzhong horse was 3.88. Nonetheless, the total value of FST multiloci clearly indicates that about 0.5% of overall genetic variation is due to line founder differences, while differences among individuals are responsible for the remaining 99.5%. In addition, the polymorphic information content (PIC) result showed that five loci (HTG7, HMS7, HMS2, AHT4, and HMS6) were highly polymorphic (PIC > 0.5) and three loci (HMS3, HTG6, and COR071) were moderate polymorphic (PIC > 0.25). Genetic distances and cluster analysis showed that the genetic relationship among 67 Guanzhong horse was generally consistent with pedigree recorded. Our results not only evaluated the genetic diversity of Chinese Guanzhong horse, but also suggested that the eight microsatellite markers might be used as subservient markers for parentage verification and individual identification in the Guanzhong horse. PMID- 29463180 TI - The association between physical activity and dietary inflammatory index on mortality risk in U.S. adults. AB - OBJECTIVE: Both diet and physical activity have been shown to be associated with reduced risk for mortality. The current study examined the individual and combined effects of the inflammatory quality of diet and physical activity levels on mortality risk. METHODS: Data from the 1999-2004 National Health and Nutrition Examination Survey were used (N = 10,610 adults 20-85 years). Participants were followed through 2011, entailing a median follow-up time of 9.6 yrs. Dietary patterns were assessed using the Dietary Inflammatory Index (DII(r)), with a higher score indicative of greater diet-related inflammation. Habitual physical activity was assessed via a 30-day recall of leisure-time physical activity as well as objectively via up to seven days of accelerometry assessment. Four lifestyle groups were created: 1) unfavorable DII and inactive (referent); 2) unfavorable DII and active; 3) favorable DII and inactive; and 4) favorable DII and active. RESULTS: Those who had a low DII score (favorable) and who self reported being active had a 39% reduced hazard of all-cause mortality (HR = 0.61; 95% CI: 0.49-0.76) when compared to those with a higher DII and were inactive. Results based on accelerometer-assessed physical activity indicate a 65% reduced hazard (HR = 0.35; 95% CI: 0.17-0.74). DII and physical activity also were individually associated with mortality in the expected direction. Specifically, DII was positively associated (HR = 1.08; 95% CI: 1.04-1.13) and physical activity inversely associated (HR = 0.97; 95% CI: 0.94-0.99) with all-cause mortality risk. CONCLUSION: The combination of consuming a more anti-inflammatory diet and having adequate levels of physical activity is associated with a reduced risk of mortality. Additional replicative work is warranted. PMID- 29463181 TI - Spared behavioral repetition effects in Alzheimer's disease linked to an altered neural mechanism at posterior cortex. AB - OBJECTIVE: Individuals with dementia of the Alzheimer type (AD) classically show disproportionate impairment in measures of working memory, but repetition learning effects are relatively preserved. As AD affects brain regions implicated in both working memory and repetition effects, the neural basis of this discrepancy is poorly understood. We hypothesized that the posterior repetition effect could account for this discrepancy due to the milder effects of AD at visual cortex. METHOD: Participants with early AD, amnestic mild cognitive impairment (MCI), and healthy controls performed a working memory task with superimposed repetition effects while electroencephalography was collected to identify possible neural mechanisms of preserved repetition effects. RESULTS: Participants with AD showed preserved behavioral repetition effects and a change in the posterior repetition effect. CONCLUSION: Visual cortex may play a role in maintained repetition effects in persons with early AD. PMID- 29463183 TI - Younger and older adults' associative memory for medication interactions of varying severity. AB - While older adults face various deficits in binding items in memory, they are often able to remember information that is deemed important. In Experiment 1, we examined how younger and older adults remember medication interactions of varying severity. There were no age differences in overall memory accuracy, but older adults' performance depended on the severity of the interactions (such that the interactions associated with the most severe health outcomes were remembered most accurately) while younger adults' did not. In Experiment 2, a similar task was designed to create interference in memory. Even with this more difficult task there were no age differences in recall accuracy, and both age groups remembered the interactions with the severe outcomes most accurately. These findings suggest that, under certain circumstances, older adults do not face deficits in associative recognition accuracy of information that varies in importance. PMID- 29463182 TI - Registered Replication Report: Dijksterhuis and van Knippenberg (1998). AB - Dijksterhuis and van Knippenberg (1998) reported that participants primed with a category associated with intelligence ("professor") subsequently performed 13% better on a trivia test than participants primed with a category associated with a lack of intelligence ("soccer hooligans"). In two unpublished replications of this study designed to verify the appropriate testing procedures, Dijksterhuis, van Knippenberg, and Holland observed a smaller difference between conditions (2% 3%) as well as a gender difference: Men showed the effect (9.3% and 7.6%), but women did not (0.3% and -0.3%). The procedure used in those replications served as the basis for this multilab Registered Replication Report. A total of 40 laboratories collected data for this project, and 23 of these laboratories met all inclusion criteria. Here we report the meta-analytic results for those 23 direct replications (total N = 4,493), which tested whether performance on a 30 item general-knowledge trivia task differed between these two priming conditions (results of supplementary analyses of the data from all 40 labs, N = 6,454, are also reported). We observed no overall difference in trivia performance between participants primed with the "professor" category and those primed with the "hooligan" category (0.14%) and no moderation by gender. PMID- 29463184 TI - Informal work-related injuries: a one year prospective study in a rural community in Serbia. AB - Work-related injuries occurring during informal work often go unreported, yet lead to significant mortality and contribute substantially to disease burden due to injury-related disability. In Serbia, injury is a leading cause of death, with work-related injuries comprising a significant proportion. This study explored the frequency of and risk factors for these injuries in a rural Serbian community. During the 12-month study period, physicians from a municipal Primary Care Centre reported all presenting injuries using a specific injury report form. One in four injuries reported occurred during informal work practices, accounting for 71% of all reported work-related injuries. These occurred within the household in 85% of cases, and were more severe in males (79%). Regarding work related injuries, informal workers were significantly older than formally employed workers, regardless of sex. Public policy should address safety improvements for informal workers, via provision of relevant training and protective equipment.

PMID- 29463186 TI - Daily Profiles of Light Exposure and Evening Use of Light-emitting Devices in Young Adults Complaining of a Delayed Sleep Schedule. AB - A number of factors can contribute to a delayed sleep schedule. An important factor could be a daily profile of light exposure favoring a later circadian phase. This study aimed to compare light exposure between 14 young adults complaining of a delayed sleep schedule and 14 matched controls and to identify possible associations between habitual light exposure and circadian phase. Exposure to white and blue light was recorded with ambulatory monitors for 7 consecutive days. Participants also noted their daily use of light-emitting devices before bedtime. Endogenous circadian phase was estimated with the dim light melatonin onset (DLMO) in the laboratory. The amplitude of the light-dark cycle to which the subjects were exposed was smaller in delayed than in control subjects, and smaller amplitude was associated with a later DLMO. Smaller amplitude was due to both decreased exposure in the daytime and increased exposure at night. Total exposure to blue light, but not to white light, was lower in delayed subjects, possibly due to lower exposure to blue-rich outdoor light. Lower daily exposure to blue light was associated with a later DLMO. Timing of relative increases and decreases of light exposure in relation to endogenous circadian phase was also compared between the 2 groups. In delayed subjects, there was a relatively higher exposure to white and blue light 2 h after DLMO, a circadian time with maximal phase-delaying effect. Delayed participants also had higher exposure to light 8 to 10 h after DLMO, which occurred mostly during their sleep episode but may have some phase-advancing effects. Self-reported use of light-emitting devices before bedtime was higher in delayed than in control subjects and was associated with a later DLMO. This study suggests that individuals complaining of a delayed sleep schedule engage in light related behaviors favoring a later circadian phase and a later bedtime. PMID- 29463187 TI - Finding Keys: A Systematic Review of Barriers and Facilitators for Refugee Children's Disclosure of Their Life Stories. AB - The systematic review presented in this article aims to reveal what supports and hampers refugee children in telling their, often traumatic, life stories. This is important to ensure that migration decisions are based on reliable information about the children's needs for protection. A systematic review was conducted in academic journals, collecting all available scientific knowledge about the disclosure of life stories by refugee minors in the context of social work, guardianship, foster care, asylum procedures, mental health assessment, and therapeutic settings. The resulting 39 studies were thoroughly reviewed with reference to what factors aided or hampered the refugee children's disclosure of their life stories. The main barriers to disclosure were feelings of mistrust and self-protection from the side of the child and disrespect from the side of the host community. The facilitators for disclosing life stories were a positive and respectful attitude of the interviewer, taking time to build trust, using nonverbal methods, providing agency to the children, and involving trained interpreters. Social workers, mentors, and guardians should have time to build trust and to help a young refugee in revealing the life story before the minor is heard by the migration authorities. The lack of knowledge on how refugee children can be helped to disclose their experiences is a great concern because the decision in the migration procedure is based on the story the child is able to disclose. PMID- 29463188 TI - Progesterone Inhibits Apoptosis in Fetal Membranes by Altering Expression of Both Pro- and Antiapoptotic Proteins. AB - OBJECTIVE: Progesterone supplementation prevents preterm birth (PTB) in some high risk women, but its mechanism of action is unknown. One-third of PTB is associated with preterm premature rupture of membranes (PPROMs). We have previously shown that progesterone inhibits basal and Tumor Necrosis Factor (TNF) alpha-induced apoptosis in an explant model of human fetal membranes. This study investigates the molecular mechanisms responsible for progesterone-mediated inhibition of apoptosis in fetal membranes. METHODS: Human fetal membranes were collected at elective cesarean at term (no labor, no infection; n = 6), washed, and pretreated with/without progesterone (125 ng/mL) for 24 hours. Thereafter, membranes were treated with/without TNFalpha (50 ng/mL) and/or progesterone for 48 hours, harvested, and homogenized. Apoptosis was determined by evaluating caspase-3, -8, and -9 activities. Expression of pro- BH3 interacting domain death against, Bc1-2 associated X protein (BID, BAX) and antiapoptotic proteins (X linked inhibitor of apoptosis protein [XIAP], Bcl-2, FLICE inhibitory protein [FLIP]) were measured by Western blot. RESULTS: TNFalpha increased apoptosis (measured by caspase-3, -8, and -9 activities) in fetal membranes, and this effect was abrogated by progesterone. Under basal conditions, progesterone suppressed expression of the proapoptotic protein, BID, by 0.45 (0.14)-fold, and increased expression of the antiapoptotic proteins, Bcl-2 and XIAP; no change was seen in BAX or FLIP. In contrast, TNFalpha increased BID expression by 5.15 (2.92)-fold, which was prevented by pretreatment with progesterone. CONCLUSIONS: Progesterone inhibits apoptosis in fetal membranes by suppressing expression of the proapoptotic protein, BID (for both basal and TNFalpha-induced apoptosis), and upregulating expression of the antiapoptotic proteins, XIAP and Bcl-2 (under basal conditions only). These data provide a mechanism by which progesterone supplementation may prevent PPROM and PTB in some women at high risk. PMID- 29463189 TI - A Qualitative Investigation of the Role of Gender in Young Women's Dating Violence in the United States. AB - The relevance of gender has been a central debate in the intimate partner violence (IPV) literature. The current qualitative study explored the role of gender in shaping the social context, meaning, and reception of young women's IPV in the United States. A total of 36 undergraduate women were recruited from a larger sample for in-depth interviews. Emergent themes suggest that women's violence was construed as nonequivalent to men's violence, including the perceived triviality of women's violence, contingencies under which women's violence is deemed acceptable, and the status of male IPV as unacceptable. Gender was important for participants and bystanders in determining whether they interpreted behaviors as meaningful acts of violence. PMID- 29463190 TI - CYFRA 21-1 predicts the efficacy of nivolumab in patients with advanced lung adenocarcinoma. AB - CYFRA 21-1 is a prognostic marker for non-small cell lung cancer. The serum CYFRA 21-1 level is also known as an adjunct for the diagnosis of lung squamous cell carcinoma. This study aimed to examine whether CYFRA 21-1 has predictive implications for nivolumab therapy in patients with advanced lung adenocarcinoma. Of the 79 patients who were treated with nivolumab therapy at the Shizuoka Cancer Center between December 2015 and September 2016, we retrospectively reviewed the data of 50 patients. The patient characteristics were as follows: age <70/>=70 years: 43 (86%)/7; male/female: 31 (62.0%)/19; Eastern Cooperative Oncology Group performance status 0-1/2: 43 (86%)/7; smoking status: no/yes: 18 (36%)/32; epidermal growth factor receptor mutation status negative/positive: 36 (72%)/14; CYFRA 21-1 >=2.2/<2.2 ng/mL: 28 (56%)/22; carcinoembryonic antigen >=5/<5 ng/mL: 29 (58%)/21; and number of prior regimens 2-3/>=4: 16 (32%)/34. With a median follow-up of 263.5 (range, 64-352) days, the median progression-free survival was 70 days. The clinical variables investigated using univariate analysis were as follows: age (p = 0.423), carcinoembryonic antigen (p = 0.888), epidermal growth factor receptor mutation status (p = 0.105), performance status (p = 0.968), sex (p = 0.210), number of prior regimens (p = 0.146), CYFRA 21-1 (p = 0.026), and smoking status (p = 0.041). A multivariate analysis identified a serum CYFRA 21-1 level >=2.2 ng/mL as an independent predictor of a favorable outcome (hazard ratio, 0.44; 95% confidence interval, 0.23-0.85; p = 0.015; median progression free survival, 155 vs 51.5 days). In conclusion, CYFRA 21-1 might be an independent predictor of outcome for patients with advanced lung adenocarcinoma treated with nivolumab. PMID- 29463191 TI - HE4 is superior to CA125 in the detection of recurrent disease in high-risk endometrial cancer patients. AB - OBJECTIVE: To date, biomarkers are not routinely used in endometrial cancer diagnosis, prognosis, and follow-up. The purpose of this study was to evaluate whether serum HE4 was related to clinicopathological risk factors and outcome. Second, the role of serum HE4 and CA125 was assessed as indicator for recurrent disease during follow-up. METHODS: A total of 174 patients with endometrial cancer between 1999 and 2009 were selected for this retrospective study. Serum HE4 and CA125 were analyzed at primary diagnosis, during follow-up, and at the time of recurrence. Correlations with clinicopathological factors were studied by univariate and multivariate survival analyses. Lead time was calculated in order to determine which serum marker was elevated prior to clinical detection of recurrent disease. RESULTS: Serum levels of HE4 and CA125 were significantly associated with high tumor grade, myometrial invasion, lymph node involvement, and advanced stage (p < 0.01). HE4 was an independent prognostic factor for reduced disease-free survival and overall survival with hazard ratios of 2.96 (95% confidence interval: 1.18-7.99) and 3.27 (95% confidence interval: 1.18 9.02), respectively. At recurrence, 75% of the patients had an elevated HE4 compared to 54% with an elevated CA125. HE4 levels were more frequently elevated in patients with distant metastasis compared to local recurrences, 67% and 37%, respectively. Serum HE4 detected a recurrence with a median of 126 days earlier than clinical confirmation. CONCLUSION: Elevated serum HE4 is an independent risk factor for reduced disease-free survival and overall survival. HE4 seems to be superior to CA125 in the detection of recurrent disease during follow-up, mainly in high-risk endometrial cancer patients who are more prone to distant metastasis. PMID- 29463192 TI - Home-based exercise for elderly patients with intermittent claudication limited by osteoarticular disorders - feasibility and effectiveness of a low-intensity programme. AB - BACKGROUND: Peripheral arterial disease (PAD) is a common cardiovascular pathology affecting mobility in elderly. Osteoarticular diseases (ODs), responsible for functional limitations and confounding leg symptoms, may interfere with exercise therapy. This study evaluates the feasibility and effectiveness of a structured home-based exercise programme on rehabilitative outcomes in a cohort of elderly PAD patients with and without coexisting ODs. PATIENTS AND METHODS: Patients were enrolled from 2002 to 2016 in an exercise programme prescribed and controlled at the hospital and based on two daily 10 minute home walking sessions below the self-selected speed. The presence and localization of ODs at baseline were derived from consultation of medical documents. The ankle-brachial index and functional outcomes, defined as speed at the onset of claudication and attainable maximal speed by an incremental treadmill test, were assessed at baseline and discharge. Feasibility was determined according to dropout rate, number of visits, duration of the programme, and adherence. RESULTS: A total of 1,251 PAD patients were enrolled (931 men; 71 +/- 9 years; 0.63 +/- 0.19 ankle-brachial index). Eight hundred sixty-four patients were free of ODs (ODfreePAD, 69 %), whereas 387 were affected by ODs (ODPAD, 31 %), predominantly located in the spine (72 %). In the logistic regression models, the presence of ODs was associated with female sex, overweight, sedentary and/or driving professions. At discharge, ODPAD and ODfreePAD did not differ in dropout rates (12 % each), programme duration (378 +/ 241 vs. 390 +/- 260 days), number of visits (7 +/- 3 each), and adherence (80 % each). Similar improvements for ODPAD and ODfreePAD were observed for the ankle brachial index (0.06 +/- 0.12 each), the speed at onset of claudication (0.7 +/- 0.7 vs. 0.7 +/- 0.8 kmh-1; p = 0.70), and maximal speed (0.4 +/- 0.6 vs. 0.4 +/- 0.6 kmh-1; p = 0.77). CONCLUSIONS: Equally satisfactory rehabilitative outcomes were observed in elderly patients with claudication limited by ODs who completed a well-tolerated, low-impact structured exercise programme.

AB - This report presents and discusses, on behalf of the Belgian College of Cardiology, the evolution of the peer review process in arrhythmology, focussing on pacemaker implantation. Data from the last 22 years are compared. The national annual increase in implants is around 1%, clinical patient characteristics remained stable over the years while dual chamber pacing was proportionally increasing. Analyses of the normalised sick sinus and complete atrioventricular block ratios revealed a quite homogenous practice between centres and patient district with the only exception of the two more crowded districts. Battery longevity and infection rate were also assessed. With an incidence of 1/1000 device-years follow-up, Belgium remains below accepted European levels. PMID- 29463194 TI - The Expression and Prognostic Impact of the PI3K/AKT/mTOR Signaling Pathway in Advanced Esophageal Squamous Cell Carcinoma. AB - The abnormal phosphatase and tensin homolog expression and activated phosphoinositide-3 kinase/Protein kinase B (AKT)/mammalian target of rapamycin signaling pathway are involved in the progression of esophageal squamous cell carcinoma. By assessing the expression pattern of key components in the phosphoinositide-3 kinase/AKT/mammalian target of rapamycin signaling pathway by immunohistochemistry in tumor and nontumor esophageal mucosa from patients with esophageal squamous cell carcinomas, we aimed to carefully explore the relationship between the various protein expressions and clinicopathological factors, as well as patient outcome. A total of 145 tumor and 145 nontumor samples from patients with esophageal squamous cell carcinoma, collected from HuaShan Hospital (Shanghai, China) were evaluated. Clinical characteristics, the targeted protein expressions (including phosphatase and tensin homolog, phosphoinositide-3 kinase, AKT, p-AKT, mammalian target of rapamycin, p-mTOR, p70S6 kinase 1, p-P70S6K1, elongation initiation factor 4E binding protein-1, and p-4E-BP1, and survival rate were analyzed. Among them, phosphoinositide-3 kinase, AKT, p-AKT, mammalian target of rapamycin, p-mTOR, elongation initiation factor 4E binding protein-1, p70S6 kinase 1, and p-P70S6K1 proteins were significantly upregulated in tumor tissue. Conversely, phosphatase and tensin homolog was largely downregulated in tumor tissue, notably in pT3-T4 tumors. Low expression of phosphatase and tensin homolog whereas high expression of mammalian target of rapamycin signaling components in tumors was closely related to the presence of lymph node metastases and advanced TNM stage (all P < .05). Moreover phosphatase and tensin homolog, mammalian target of rapamycin, and p70S6 kinase 1 were correlated with overall survival as well as p-mTOR was correlated with progression-free survival (all P < .05). Overexpression of mammalian target of rapamycin was proved to be an independent adverse prognostic factor for overall survival in esophageal squamous cell carcinomas. Our results suggest that the phosphoinositide-3 kinase/AKT/mammalian target of rapamycin signaling pathway is activated in esophageal squamous cell carcinoma, with the low expression of phosphatase and tensin homolog and the high expression of the mammalian target of rapamycin component proteins (both total and phosphorylated) in tumor tissue. Our result might offer a new strategy for specific targeted therapy and prognostic assessment in esophageal cancer. PMID- 29463195 TI - Physical workload and musculoskeletal disorders in back, shoulders and neck among welders. AB - This study aimed to determine the effect of the physical workload on the back, neck and shoulders of welders. The prevalence of musculoskeletal symptoms was assessed using the Nordic questionnaire among 15 welders. The physical workload of the neck, back and upper arms was then measured by means of inclinometry as the welders were working. The results revealed that the highest prevalence of musculoskeletal disorders during the previous 12 months was in the lower back and shoulders. The median trunk and neck flexion were significantly associated with back and neck pain in welders with symptoms during the past year (p < 0.05). Physical exposure in welders with pain was characterized by significantly more awkward postures and percentage of time spent with the trunk and neck flexed more than 20 degrees . The nature of their work and the design of their workstations may be causes of the symptoms they experienced during work. PMID- 29463196 TI - Reflection on the Professor-Priming Replication Report. PMID- 29463197 TI - Cephalic pancreaticoduodenectomy with preservation of a right coronary artery bypass graft using the right gastro-epiploic artery: a case report. AB - INTRODUCTION: Pancreatic cancer is a rare disease with a high mortality rate, for which complete surgical resection, when possible, is the preferred therapeutic. Pancreaticoduodenectomy represents the surgical technique of choice. Abdominal surgeons can be faced with the challenge of patients with a history of coronary artery bypass graft in which the right gastro-epiploic artery is used. CASE REPORT: We report the case of a patient with an adenocarcinoma of the pancreatic head, stage IIA, having previously undergone a triple coronary artery bypass, one of which being a right gastro-epiploic graft. Our challenge was underlined by the necessity of a complete oncological resection through a cephalic pancreaticoduodenectomy while preserving the necessary cardiac perfusion via the right gastro-epiploic artery. CONCLUSION: We have been able to preserve a right gastro-epiploic artery as a coronary bypass during a cephalic pancreaticoduodenectomy for a cephalic pancreatic adenocarcinoma. We have successfully been able to preserve and re-implant the right gastro-epiploic artery to the origin of the gastroduodenal artery while insuring R0 resection of the tumor. A coronary artery bypass using the right gastro-epiploic artery should therefore not be considered as an obstacle to a Whipple's procedure if total oncological resection is obtainable. PMID- 29463199 TI - Airborne particulate matter impairs corneal epithelial cells migration via disturbing FAK/RhoA signaling pathway and cytoskeleton organization. AB - BACKGROUND: Cornea is the outmost structure of the eye and exposed directly to the air pollution. However, little is known about the effect of PM2.5 on corneal epithelium, which is critical for maintenance of cornea homeostasis and visual function. OBJECTIVE: We investigated the influence of PM2.5 exposure on corneal epithelial migration and the possible mechanisms involved in the process. METHODS: We observed wound healing in mouse model of cornea abrasion, evaluated the migration and mobility of cultured corneal epithelial cells with wound scratch assay and Transwell migration assay, detected the phosphorylation and interaction of FAK/paxillin with immunofluorescence and immunoprecipitation, and determined the RhoA activity and actin reorganization, in response to PM2.5 exposure. RESULTS: Exposure to PM2.5 remarkably inhibited corneal epithelial cell migration both in mouse model of corneal abrasion and in cell culture model. We found the phosphorylation and interaction of FAK/paxillin, RhoA activity as well as actin reorganization were suppressed by PM2.5 exposure. Moreover, formation of ROS might play a role in the action of PM2.5. CONCLUSIONS: PM2.5 exposure could result in delay of corneal epithelium wound healing by inhibiting cell migration, thus more attention should be paid to the potential risk of corneal infection and effort should be made to protect eyes against impairment induced by PM2.5. PMID- 29463198 TI - A network approach for provisional assay recognition of a Hendra virus antibody ELISA: test validation with low sample numbers from infected horses. AB - Obtaining statistically sound numbers of sera from Hendra virus (HeV)-infected horses is problematic because affected individuals usually die or are euthanized before developing a serum antibody response. As a consequence, test validation becomes a challenge. Our approach is an extension of OIE principles for provisional recognition and included 7 validation panels tested across multiple laboratories that provided estimates for test performance characteristics. At a 0.4 S/P cutoff, 16 of 19 sera from HeV-infected horses gave positive results in the HeV soluble G, indirect ELISA (HeVsG iELISA; DSe 84.2% [95% CI: 60.4-96.6%]); 463 of 477 non-infected horse sera tested negative (DSp 97.1% [95% CI: 95.1 98.4%]). The HeVsG iELISA eliminated almost all false-positive results from the previously used HeV iELISA, with marginally decreased relative sensitivity. Assay robustness was evaluated in inter-laboratory and proficiency testing panels. The HeVsG iELISA is considered to be fit for purpose for serosurveillance and international movement of horses when virus neutralization is used for follow-up testing of positive or inconclusive serum samples. PMID- 29463201 TI - Effectiveness of GonaCon as an immunocontraceptive in colony-housed cats. AB - Objectives Non-surgical contraceptive management of free-roaming cat populations is a global goal for public health and humane reasons. The objectives of this study were to measure the duration of contraception following a single intramuscular injection of a gonadotropin-releasing hormone-based vaccine (GonaCon) and to confirm its safe use in female cats living in colony conditions. Methods GonaCon (0.5 ml/cat) was administered intramuscularly to 20 intact female cats (queens), and saline was administered to 10 queens serving as sham-treated controls. Beginning in late February, 4 months after injection, all cats were housed with fertile male cats in a simulated colony environment. Time to pregnancy, fetal counts and vaccine-elicited injection-site reactions were evaluated. Results All control cats (n = 10/10) and 60% (n = 12/20) of vaccinated cats became pregnant within 4 months of the introduction of males. Two additional vaccinates became pregnant (70%; n = 14/20) within 1 year of treatment. Average fetal counts were significantly lower in vaccinated cats than in control cats. Vaccinates had a significantly longer ( P = 0.0120) median time to conception (212 days) compared with controls (127.5 days). Injection-site reactions ranging from swelling to transient granulomatous masses were observed in 45% (n = 9/20) of vaccinated cats. Conclusions and relevance A single dose of GonaCon provided contraception lasting for a minimum of 1 year in 30% (n = 6/20) of treated cats. The level of contraception induced by this GonaCon dose and vaccine lot was not sufficiently effective to be recommended for use in free-roaming cats. PMID- 29463202 TI - Development, initial validation and reliability testing of a web-based, generic feline health-related quality-of-life instrument. AB - Objectives The objective of this study was to develop a valid, reliable web based, generic feline health-related quality-of-life (HRQoL) questionnaire instrument to measure the affective impact of chronic disease. Methods A large initial item pool, obtained through interviews with cat owners, was reduced using predetermined criteria, survey scores for relevance and clarity, and the ability of individual items to discriminate between healthy and sick cats when owners completed a prototype questionnaire. Using these data, factor analysis was used to derive a scoring algorithm and provide evidence for factorial validity. Validity was demonstrated further in a field trial using a 'known groups' approach (sick vs healthy cats will have a different HRQoL profile, and the HRQoL profile of cats will deteriorate as comorbidities increase). Test-retest reliability was assessed using intra-class correlation coefficients (ICC). Results In total, 165 items were reduced to 20 and, on the basis of a factor analysis that explained 72.3% of the variation in scores input by 71 owners of 30 healthy and 41 sick cats using the prototype, these were allocated to three domains (vitality, comfort and emotional wellbeing [EWB]) with a scoring algorithm derived using item loadings. Subsequently, the owners of 36 healthy and 58 sick cats completed one or two (n = 48) assessments. Median scores (healthy vs sick) for all domains were significantly different ( P <0.001), 78% of cats were correctly classified as healthy or sick and for comorbidities the correlation coefficients were moderate (vitality 0.64; comfort 0.63; EWB 0.50). Test-retest reliability was good (ICC vitality 0.635; comfort 0.716; EWB 0.853). Conclusions and relevance This study provides initial evidence for the validity and reliability of a novel HRQoL instrument to aid the assessment and management of chronic diseases of cats.

AB - The aim of this article was to explore the link between postmenopausal status according to years since menopause (YSM) and the prevalence of metabolic syndrome (MetS). This survey was conducted from January 2012 to August 2013. A total of 6022 women (3511, 58.3% were post-menopause) from Rural Northeast China were randomly selected and examined. The prevalence of the MetS was significantly higher in postmenopausal women (Post-MW) than in premenopausal women (Pre-MW) (55.0% vs. 33.1%, p .001). The risk for MetS in Post-MW increased with the number of YSM, reaching the peak level in the 5- to 9-year group (OR, 1.55; 95% CI, 1.23 1.96), and then decreased. The 5- to 9-year group had the highest risk of high glucose (OR, 1.48; 95% CI, 1.20-1.83) and high triglycerides (adjusted OR, 1.92; 95% CI, 1.53-2.41) whereas the risk for abdominal obesity, high BP, and low HDL-C was not significantly associated with the number of YSM. These findings suggested that, in China, Post-MW with 5-9 YSMs had the highest risk of MetS. YSM can be a useful screening tool to identify women at high risk for MetS. PMID- 29463204 TI - Intraindividual variability in neurocognitive performance is associated with time based prospective memory in older adults. AB - INTRODUCTION: Older adults demonstrate poorer prospective memory (PM) performance than younger adults, particularly for time-based cues and other strategically demanding PM tasks. Intraindividual variability (IIV) in neurocognitive test performance is an index of cognitive control that may be related to the execution of strategically demanding PM tasks. METHOD: Participants included 194 older Australian adults (age 50 to 88 years) who completed the Memory for Intentions Screening Test (MIST), the Prospective and Retrospective Memory Questionnaire (PRMQ), and clinical measures of executive functions. A measure of naturalistic time-based PM was also administered, in which participants were asked to call the examiner 24 hours after their appointment to report how many hours they slept. IIV was calculated as the mean-adjusted coefficient of variation (CoV) across subtests of the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). RESULTS: IIV was significantly associated with time-based PM in the laboratory, independent of demographics. Additionally, IIV significantly predicted performance on a naturalistic time-based PM trial, independent of demographics and chronic medical conditions. IIV was not related to event-based laboratory PM or self-reported PM symptoms in daily life. Clinical measures of executive functions were similarly associated with time-based PM and the naturalistic PM task, but not with event-based PM or subjective PM symptoms. CONCLUSIONS: These results indicate that cognitive control, as indexed by IIV in neurocognitive performance, may play a role in naturalistic PM, as well as in highly strategic, but not automatic, laboratory-based PM among older adults.

AB - INTRODUCTION: Diabetic patients have been known to have a higher incidence of frozen shoulder. Arthroscopic capsular release has been described for diabetic frozen shoulder refractory to non-surgical treatment. We describe our single surgeon experience of this procedure done in Asian patients presenting with diabetic frozen shoulder. RESULTS: Data were prospectively collected from 25 patients from 2007 to 2008, who underwent arthroscopic capsular release for frozen shoulder with diabetes mellitus. This included the University of California-Los Angeles (UCLA) Shoulder Score by an independent observer. Mean follow-up duration was 44.3 +/- 22 months with the age of 57.3 +/- 10.9 years at the time of surgery. Mean duration of symptoms prior to surgery was 8.9 +/- 7.5 months. Ten right shoulders and 15 left shoulders were operated on. Arthroscopic capsular release was performed in the beach chair position with the aid of a 90 degrees electrocautery hook, from the rotator interval to posterior capsule. Significant improvement was observed in the UCLA scores post-operatively (preoperative total score 15.8 +/- 3.6 vs. post-operative 33.3 +/- 2.5, p < 0.00), including all domains of pain (3.9 +/- 1.8 vs. 9.4 +/- 0.9, p < 0.00), function (4.8 +/- 1.7 vs. 9.4 +/- 1.4, p < 0.00), active forward flexion (2.6 +/- 0.7 vs. 4.6 +/- 0.6, p < 0.00) and satisfaction (0.0 +/- 0.0 vs. 5.0 +/- 0.0, p < 0.00). No significant correlation between duration of symptoms and UCLA scores. Significant improvement was observed in forward flexion (preoperative 100.4 +/- 18.8 degrees vs. post-operative 157.6 +/- 15.9 degrees , p < 0.00) and external rotation (preoperative 14.4 +/- 6.34 degrees vs. post-operative 63.8 +/- 8.3 degrees , p < 0.00). Although the duration of symptoms correlated significantly with preoperative forward flexion ( r = 0.443 and p < 0.027), there was no significant correlation with post-operative forward flexion ( r = 0.023 and p < 0.91). No axillary nerve palsy observed. CONCLUSION: The diabetic frozen shoulder can be treated favourably with arthroscopic capsular release and the duration of symptoms prior to surgery does not affect the outcomes.

PMID- 29463207 TI - Effects of flexible ureteroscopy on renal blood flow: a prospective evaluation. AB - OBJECTIVE: This study aimed to investigate the effects of flexible ureteroscopy (F-URS) on renal blood flow using renal Doppler ultrasound (US). MATERIALS AND METHOD: Patients undergoing F-URS were scheduled for Doppler US preoperatively and postoperatively. Peak systolic velocity (PSV), end-diastolic velocity (EDV), resistive index (RI) and pulsatility index (PI) were reported. Technical details, operation time, stone characteristics and complications were recorded. Patients were grouped as 9.5/11.5-Flex-X2, 10/12-Flex-X2, 10/12-Flex-XC, 12/14-Flex-X2 and 12/14-Flex-XC, with 28, six, three, seven and two patients in each group, respectively. RESULTS: Forty-six patients with a mean age of 41.24 years and stone volume of 1685 mm3 were enrolled. The PSV, EDV, PI and RI of renal arteries in all groups in preoperative and postoperative periods were similar. Arcuate artery measurements in all groups were also similar in preoperative and postoperative periods, without any significant difference except in two parameters: RI in the 9.5/11.5-Flex-X2 group and PSV in the 12/14-Flex-X2 group. The resistive index in the arcuate artery of the 9.5/11.5-Flex-X2 group was increased from 0.59 to 0.62 cm/sec postoperatively. The PSV in the arcuate artery of the 12/14-Flex-X2 group was decreased from 30.9 to 27.2 cm/sec. Three patients had urinary tract infections postoperatively and two had sepsis. CONCLUSION: This study suggests that compatible ureteroscope-ureteral access sheath combinations with a lumen difference of more than 1.5 Fr can provide safe outcomes in terms of renal blood flow. F-URS can safely be performed in terms of renal perfusion and complication rates with appropriate equipment and instruments. PMID- 29463208 TI - The VAAST Variant Prioritizer (VVP): ultrafast, easy to use whole genome variant prioritization tool. AB - BACKGROUND: Prioritization of sequence variants for diagnosis and discovery of Mendelian diseases is challenging, especially in large collections of whole genome sequences (WGS). Fast, scalable solutions are needed for discovery research, for clinical applications, and for curation of massive public variant repositories such as dbSNP and gnomAD. In response, we have developed VVP, the VAAST Variant Prioritizer. VVP is ultrafast, scales to even the largest variant repositories and genome collections, and its outputs are designed to simplify clinical interpretation of variants of uncertain significance. RESULTS: We show that scoring the entire contents of dbSNP (> 155 million variants) requires only 95 min using a machine with 4 cpus and 16 GB of RAM, and that a 60X WGS can be processed in less than 5 min. We also demonstrate that VVP can score variants anywhere in the genome, regardless of type, effect, or location. It does so by integrating sequence conservation, the type of sequence change, allele frequencies, variant burden, and zygosity. Finally, we also show that VVP scores are consistently accurate, and easily interpreted, traits not shared by many commonly used tools such as SIFT and CADD. CONCLUSIONS: VVP provides rapid and scalable means to prioritize any sequence variant, anywhere in the genome, and its scores are designed to facilitate variant interpretation using ACMG and NHS guidelines. These traits make it well suited for operation on very large collections of WGS sequences. PMID- 29463209 TI - Characterisation of Zika virus infection in primary human astrocytes. AB - BACKGROUND: The recent Zika virus (ZIKV) outbreak has linked ZIKV with microcephaly and other central nervous system pathologies in humans. Astrocytes are among the first cells to respond to ZIKV infection in the brain and are also targets for virus infection. In this study, we investigated the interaction between ZIKV and primary human brain cortical astrocytes (HBCA). RESULTS: HBCAs were highly sensitive to representatives of both Asian and African ZIKV lineages and produced high viral yields. The infection was associated with limited immune cytokine/chemokine response activation; the highest increase of expression, following infection, was seen in CXCL-10 (IP-10), interleukin-6, 8, 12, and CCL5 (RANTES). Ultrastructural changes in the ZIKV-infected HBCA were characterized by electron tomography (ET). ET reconstructions elucidated high-resolution 3D images of the proliferating and extensively rearranged endoplasmic reticulum (ER) containing viral particles and virus-induced vesicles, tightly juxtaposed to collapsed ER cisternae. CONCLUSIONS: The results confirm that human astrocytes are sensitive to ZIKV infection and could be a source of proinflammatory cytokines in the ZIKV-infected brain tissue. PMID- 29463210 TI - Barriers to and strategies for addressing the availability, accessibility, acceptability and quality of the sexual, reproductive, maternal, newborn and adolescent health workforce: addressing the post-2015 agenda. AB - BACKGROUND: In a post-2015 development agenda, achieving Universal Health Coverage (UHC) for women and newborns will require a fit-for-purpose and fit-to practice sexual, reproductive, maternal, adolescent and newborn health (SRMNAH) workforce. The aim of this paper is to explore barriers, challenges and solutions to the availability, accessibility, acceptability and quality (AAAQ) of SRMNAH services and workforce. METHODS: The State of the World's Midwifery report 2014 used a broad definition of midwifery ("the health services and health workforce needed to support and care for women and newborns") and provided information about a wide range of SRMNAH workers, including doctors, midwives, nurses and auxiliaries. As part of the data collection, 36 out of the 73 participating low- and middle-income countries conducted a one-day workshop, involving a range of different stakeholders. Participants were asked to discuss barriers to the AAAQ of SRMNAH workers, and to suggest strategies for overcoming the identified barriers. The workshop was facilitated using a discussion guide, and a rapporteur took detailed notes. A content analysis was undertaken using N-Vivo software and the AAAQ model as a framework. RESULTS: Across the 36 countries, about 800 participants attended a workshop. The identified barriers to AAAQ of SRMNAH workers included: insufficient size of the workforce and inequity in its distribution, lack of transportation, user fees and out of pocket payments. In some countries, respondents felt that women mistrusted the workforce, and particularly midwives, due to cultural differences, or disrespectful behaviour towards service users. Quality of care was undermined by a lack of supplies/equipment and inadequate regulation. Against these, countries identified a set of solutions including adequate workforce planning supported by a fast and equitable deployment system, aligned with the principles of UHC. Acceptability and quality could be improved with the provision of respectful care as well as strategies to improve education and regulation. CONCLUSIONS: The number and scale of the barriers still needing to be addressed in these 36 countries was significant. Adequate planning and policies to support the development of the SRMNAH workforce and its equitable distribution are a priority. Enabling strategies need to be put in place to improve the status and recognition of midwives, whose role is often undervalued. PMID- 29463211 TI - TEAM-UP for quality: a cluster randomized controlled trial protocol focused on preventing pressure ulcers through repositioning frequency and precipitating factors. AB - BACKGROUND: Pressure ulcers/injuries (PrUs), a critical concern for nursing homes (NH), are responsible for chronic wounds, amputations, septic infections, and premature deaths. PrUs occur most commonly in older adults and NH residence is a risk factor for their development, with at least one of every nine U.S. NH residents experiencing a PrU and many NHs having high incidence and prevalence rates, in some instances well over 20%. PrU direct treatment costs are greater than prevention costs, making prevention-focused protocols critical. Current PrU prevention protocols recommend repositioning residents at moderate, high, and severe risk every 2 h. The advent of visco-elastic (VE) high-density foam support surfaces over the past decade may now make it possible to extend the repositioning interval to every 3 or 4 h without increasing PrU development. The TEAM-UP (Turn Everyone And Move for Ulcer Prevention) study aims to determine: 1) whether repositioning interval can be extended for NH residents without compromising PrU incidence and 2) how changes in medical severity interact with changes in risk level and repositioning schedule to predict PrU development. METHODS: In this proposed cluster randomized study, 9 NHs will be randomly assigned to one of three repositioning intervals (2, 3, or 4 h) for a 4-week period. Each enrolled site will use a single NH-wide repositioning interval as the standard of care for residents at low, moderate, and high risk of PrU development (N = 951) meeting the following criteria: minimum 3-day stay, without PrUs, no adhesive allergy, and using VE support surfaces (mattresses). An FDA cleared patient monitoring system that records position/movement of these residents via individual wireless sensors will be used to visually cue staff when residents need repositioning and document compliance with repositioning protocols. DISCUSSION: This study will advance knowledge about repositioning frequency and clinically assessed PrU risk level in relation to PrU incidence and medical severity. Outcomes of this research will contribute to future guidelines for more precise preventive nursing practices and refinement of PrU prevention guidelines. TRIAL REGISTRATION: Clinical Trial Registration: NCT02996331 . PMID- 29463212 TI - The genome of Austrofundulus limnaeus offers insights into extreme vertebrate stress tolerance and embryonic development. AB - BACKGROUND: The annual killifish Austrofundulus limnaeus inhabits ephemeral ponds in northern Venezuela, South America, and is an emerging extremophile model for vertebrate diapause, stress tolerance, and evolution. Embryos of A. limnaeus regularly experience extended periods of desiccation and anoxia as a part of their natural history and have unique metabolic and developmental adaptations. Currently, there are limited genomic resources available for gene expression and evolutionary studies that can take advantage of A. limnaeus as a unique model system. RESULTS: We describe the first draft genome sequence of A. limnaeus. The genome was assembled de novo using a merged assembly strategy and was annotated using the NCBI Eukaryotic Annotation Pipeline. We show that the assembled genome has a high degree of completeness in genic regions that is on par with several other teleost genomes. Using RNA-seq and phylogenetic-based approaches, we identify several candidate genes that may be important for embryonic stress tolerance and post-diapause development in A. limnaeus. Several of these genes include heat shock proteins that have unique expression patterns in A. limnaeus embryos and at least one of these may be under positive selection. CONCLUSION: The A. limnaeus genome is the first South American annual killifish genome made publicly available. This genome will be a valuable resource for comparative genomics to determine the genetic and evolutionary mechanisms that support the unique biology of annual killifishes. In a broader context, this genome will be a valuable tool for exploring genome-environment interactions and their impacts on vertebrate physiology and evolution. PMID- 29463213 TI - MCM family in HCC: MCM6 indicates adverse tumor features and poor outcomes and promotes S/G2 cell cycle progression. AB - BACKGROUND: Minichromosome Maintenance family (MCMs), as replication licensing factors, is involved in the pathogenesis of tumors. Here, we investigated the expression of MCMs and their values in hepatocellular carcinoma (HCC). METHODS: MCMs were analyzed in 105 samples including normal livers (n = 15), cirrhotic livers (n = 40), HCC (n = 50) using quantitative polymerase chain reaction (qPCR) (Cohort 1). Significantly up-regulated MCMs were verified in 102 HCC and matched peritumoral livers using PCR (Cohort 2), and the correlations with clinical features and outcomes were determined. In addition, the focused MCMs were analyzed in parallel immunohistochemistry of 345 samples on spectrum of hepatocarcinogenesis (Cohort 3) and queried for the potential specific role in cell cycle. RESULTS: MCM2-7, MCM8 and MCM10 was significantly up-regulated in HCC in Cohort 1. In Cohort 2, overexpression of MCM2-7, MCM8 and MCM10 was verified and significantly correlated with each other. Elevated MCM2, MCM6 and MCM7 were associated with adverse tumor features and poorer outcomes. In Cohort 3, MCM6 exhibited superior HCC diagnostic performance compared with MCM2 and MCM7 (AUC: 0.896 vs. 0.675 and 0.771, P < 0.01). Additionally, MCM6 other than MCM2 and MCM7 independently predicted poorer survival in 175 HCC patients. Furthermore, knockdown of MCM6 caused a delay in S/G2-phase progression as evidenced by down regulation of CDK2, CDK4, CyclinA, CyclinB1, CyclinD1, and CyclinE in HCC cells. CONCLUSIONS: We analyze MCMs mRNA and protein levels in tissue samples during hepatocarcinogenesis. MCM6 is identified as a driver of S/G2 cell cycle progression and a potential diagnostic and prognostic marker in HCC. PMID- 29463215 TI - Association of differential miRNA expression with hepatic vs. peritoneal metastatic spread in colorectal cancer. AB - BACKGROUND: Though peritoneal carcinomatosis reflects a late stage of colorectal cancer (CRC), only few patients present with synchronous or metachronous liver metastases alongside their peritoneal carcinomatosis. It is hypothesized that this phenomenon may be causally linked to molecular characteristics of the primary CRC. This study used miRNA profiling of primary CRC tissue either metastasized to the liver, to the peritoneum or not metastasized at all thus to identify miRNAs potentially associated with defining the site of metastatic spread in CRC. METHODS: Tissue of the primary tumor stemming from CRC patients diagnosed for either liver metastasis (LM; n = 10) or peritoneal carcinomatosis (PER; n = 10) was analyzed in this study. Advanced CRC cases without metastasis (M0; n = 3) were also included thus to select on those miRNAs most potentially associated with determining metastatic spread in general. miRNA profiling of 754 different miRNAs was performed in each group. MiRNAs being either differentially expressed comparing PER and LM or even triple differentially expressed (PER vs. LM vs. M0) were identified. Differentially expressed miRNAs were further validated by in silico and functional analysis. RESULTS: Comparative analysis identified 41 miRNAs to be differentially expressed comparing primary tumors metastasized to the liver as opposed to those spread to the peritoneum. A set of 31 miRNAs was significantly induced in primary tumors that spread to the peritoneum (PER), while the remaining 10 miRNAs were found to be repressed. Out of these 41 miRNAs a number of 25 miRNAs was triple-differentially expressed (i.e. differentially expressed comparing LM vs. PER vs. M0). The latter underwent in silico analysis. Finally, we demonstrated that miR-31 down-regulated c-MET in DLD-1 colon cancer cells. CONCLUSIONS: This study demonstrates that CRC primary tumors spread to the peritoneum vs. metastasized to the liver display significantly different miRNA profiles. Larger patient cohorts will be needed to validate whether determination of e.g. miR-31 may aid to predict the course of disease and whether this may help to create individualized follow up or treatment protocols. To determine whether certain miRNAs may be involved in regulating the metastatic potential of CRC, functional studies will be essential. PMID- 29463214 TI - Genome mining for peptidases in heat-tolerant and mesophilic fungi and putative adaptations for thermostability. AB - BACKGROUND: Peptidases (EC 3.4) consist of a large group of hydrolytic enzymes that catalyze the hydrolysis of proteins accounting for approximately 65% of the total worldwide enzyme production. Peptidases from thermophilic fungi have adaptations to high temperature that makes them adequate for biotechnological application. In the present study, we profiled the genomes of heat-tolerant fungi and phylogenetically related mesophilic species for genes encoding for peptidases and their putative adaptations for thermostability. RESULTS: We generated an extensive catalogue of these enzymes ranging from 241 to 820 peptidase genes in the genomes of 23 fungi. Thermophilic species presented the smallest number of peptidases encoding genes in relation to mesophilic species, and the peptidases families with a greater number of genes were the most affected. We observed differences in peptidases in thermophilic species in comparison to mesophilic counterparts, at (i) the genome level: a great reduction in the number of peptidases encoding genes that harbored a higher number of copies; (ii) in the primary protein structure: shifts in proportion of single or groups of amino acids; and (iii) in the three-dimensional structure: reduction in the number of internal cavities. Similar results were reported for extremely thermophilic proteins, but here we show for the first time that several changes also occurred on the moderate thermophilic enzymes of fungi. In regards to the amino acids composition, peptidases from thermophilic species in relation to the mesophilic ones, contained a larger proportion of Ala, Glu, Gly, Pro, Arg and Val residues and a lower number of Cys, His, Ile, Lys, Met, Asn, Gln, Ser, Thr and Trp residues (P < 0.05). Moreover, we observed an increase in the proportion of hydrophobic and charged amino acids and a decrease in polar amino acids. CONCLUSIONS: Although thermophilic fungi present less genes encoding for peptidases, these have adaptations that could play a role in thermal resistance from genome to protein structure level. PMID- 29463216 TI - Long non-coding RNA HOTAIR polymorphism and susceptibility to cancer: an updated meta-analysis. AB - BACKGROUND: An increasing number of publications are drawing attention to the associations between six common polymorphisms in HOX transcript anti-sense RNA (HOTAIR) and the risk of cancers, while these results have been controversial and inconsistent. We conducted an up-to-date meta-analysis to pool eligible studies and to further explore the possible relationships between HOTAIR polymorphisms (rs920778, rs7958904, rs12826786, 4,759,314, rs874945, and rs1899663) and cancer risk. METHODS: A systematic retrieval was conducted up to 1 July 2017 in the PubMed, Web of Science, and CNKI databases. Eighteen eligible publications including 45 case-control studies with 58,601subjects were enrolled for assessing the associations between the 6 polymorphisms in HOTAIR and cancer risk. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were analyzed to reveal the polymorphisms and susceptibility to cancer. All the statistical analyses were performed using STATA 11.0 software. RESULTS: The pooled analyses detected significant associations between the rs920778 polymorphism and increased susceptibility to cancer in recessive, dominant, allelic, homozygous, and heterozygous models. For the rs7958904 polymorphism, we obtained the polymorphism significantly decreased susceptibility to overall cancer risk among five genetic models rather than recessive and homozygous models. For the rs12826786 polymorphism, we identified it significantly increased susceptibility to cancer risk in all genetic models rather than heterozygous models. However, no significant association was found between the rs1899663, rs874945, and rs4759314 polymorphisms and susceptibility of cancer. CONCLUSION: These findings of the meta-analysis suggest that HOTAIR polymorphism may contribute to cancer susceptibility. PMID- 29463217 TI - Elucidation of cross-species proteomic effects in human and hominin bone proteome identification through a bioinformatics experiment. AB - BACKGROUND: The study of ancient protein sequences is increasingly focused on the analysis of older samples, including those of ancient hominins. The analysis of such ancient proteomes thereby potentially suffers from "cross-species proteomic effects": the loss of peptide and protein identifications at increased evolutionary distances due to a larger number of protein sequence differences between the database sequence and the analyzed organism. Error-tolerant proteomic search algorithms should theoretically overcome this problem at both the peptide and protein level; however, this has not been demonstrated. If error-tolerant searches do not overcome the cross-species proteomic issue then there might be inherent biases in the identified proteomes. Here, a bioinformatics experiment is performed to test this using a set of modern human bone proteomes and three independent searches against sequence databases at increasing evolutionary distances: the human (0 Ma), chimpanzee (6-8 Ma) and orangutan (16-17 Ma) reference proteomes, respectively. RESULTS: Incorrectly suggested amino acid substitutions are absent when employing adequate filtering criteria for mutable Peptide Spectrum Matches (PSMs), but roughly half of the mutable PSMs were not recovered. As a result, peptide and protein identification rates are higher in error-tolerant mode compared to non-error-tolerant searches but did not recover protein identifications completely. Data indicates that peptide length and the number of mutations between the target and database sequences are the main factors influencing mutable PSM identification. CONCLUSIONS: The error-tolerant results suggest that the cross-species proteomics problem is not overcome at increasing evolutionary distances, even at the protein level. Peptide and protein loss has the potential to significantly impact divergence dating and proteome comparisons when using ancient samples as there is a bias towards the identification of conserved sequences and proteins. Effects are minimized between moderately divergent proteomes, as indicated by almost complete recovery of informative positions in the search against the chimpanzee proteome (~90%, 6-8 Ma). This provides a bioinformatic background to future phylogenetic and proteomic analysis of ancient hominin proteomes, including the future description of novel hominin amino acid sequences, but also has negative implications for the study of fast-evolving proteins in hominins, non-hominin animals, and ancient bacterial proteins in evolutionary contexts. PMID- 29463218 TI - Effects of cardiorespiratory fitness and weight status on knowledge of physical activity and fitness, attitude toward physical education, and physical activity. AB - BACKGROUND: The purpose of this study was to examine the effects of cardiorespiratory fitness and weight status on knowledge of physical activity and fitness (PAF knowledge), attitude toward physical education (PE), and physical activity. METHODS: A total of 343 middle school students participated in the study (Age: M/SD = 12.76/.94, ranging from 11 to 14 years old). PE MetricsTM was used to measure PAF knowledge, and Attitude toward Physical Education Questionnaire and Youth Activity Profile were used to measure attitude, physical activity and sedentary behavior. Fitness and weight status were assessed using FitnessGram and converted to in Healthy Fitness Zone (HFZ) or Not in HFZ. RESULTS: Two-way multivariate analyses of covariance (MANCOVA; gender and grade as covariates) showed a significant group effect for cardiorespiratory fitness (LambdaPilla = .07, F4,255 = 5.03, p = .001, [Formula: see text] = .07) but not for weight status (p = .57). PAF knowledge (F1,258 = 9.49, p < .01, [Formula: see text]= .04), attitude (F1,258 = 4.45, p < .05, [Formula: see text]= .02) and sedentary behavior (F1,258 = 6.89, p < .01, [Formula: see text]= .03) all favored the HFZ group. CONCLUSIONS: The findings reinforce the importance of promoting cardiorespiratory fitness in middle school PE as students acquire attitude, knowledge, and behaviors needed for active-living. PMID- 29463220 TI - Interferon alpha-2a treatment for refractory Behcet uveitis in Korean patients. AB - BACKGROUND: To evaluate therapeutic outcomes of interferon alpha-2a (IFNalpha2a) treatment in patients with Behcet's disease who were refractory to immunosuppressive agents. METHODS: This retrospective case series reviewed the medical records of 5 patients with refractory Behcet uveitis from January 2011 to February 2017. IFNalpha2a was administered at a dose of 3 million IU 3 times per week. Clinical response, relapse rate, and change of visual acuity were evaluated. RESULTS: The mean age of patients was 39.60 +/- 9.21 years, and the median treatment duration was 6 months. Four of the 5 patients (80%) presented with responses to IFNalpha2a without any uveitis attack during the treatment period. The mean number of uveitis attacks/year per patient during the treatment was 0.40 +/- 0.89. The mean log of the Minimum Angle of Resolution visual acuity improved from 1.44 +/- 0.38 at baseline to 1.02 +/- 0.58 at the final follow up. CONCLUSIONS: IFNalpha2a is an effective therapy for Behcet uveitis refractory to conventional immunosuppressants in Korean patients. PMID- 29463219 TI - Perceived acceptability and preferences for low-intensity early activity interventions of older hospitalized medical patients exposed to bed rest: a cross sectional study. AB - BACKGROUND: Hospitalized older patients spend most of their time in bed, putting them at risk of experiencing orthostatic intolerance. Returning persons to their usual upright activity level is the most effective way to prevent orthostatic intolerance but some older patients have limited activity tolerance, supporting the need for low-intensity activity interventions. Consistent with current emphasis on patient engagement in intervention design and evaluation, this study explored older hospitalized patients' perceived acceptability of, and preference for, two low-intensity early activity interventions (bed-to-sitting and sitting to-walking), and characteristics (gender, illness severity, comorbidity, illnesses and medications with orthostatic effects, and baseline functional capacity) associated with perceived acceptability and preference. METHODS: A convenience sample was recruited from in-patient medical units of two hospitals in Ontario, Canada and included 60 cognitively intact adults aged 65+ who were admitted for a medical condition within the past 72 h, spent >= 24 consecutive hours on a stretcher or in bed, presented with >= 2 chronic diseases, understood English, and were able to ambulate before admission. A cross-sectional observational design was used. Participants were presented written and oral descriptions and a 2-min video of each intervention. The sequence of the interventions' presention was randomized. Following the presentation, a research nurse administered measures of perceived acceptability and preference, and collected health and demographic data. Perceived acceptability and preference for the interventions were measured using the Treatment Acceptability and Preferences Scale. Illness severity was measured using the Modified Early Warning Score. Comorbidity was assessed with the Age Adjusted Charlson Comorbidity Scale and the Cumulative Illness Rating Scale - for Geriatrics. Baseline functional capacity was measured using the Duke Activity Status Index. RESULTS: Participants' perceived acceptability of both interventions clustered above the scale midpoint. Most preferred the sitting-to-walking intervention (n = 26; 43.3%). While none of the patient characteristics were associated with intervention acceptability, illness severity (odds ratio = 1.9, p = 0.04) and medications with orthostatic effects (odds ratio = 9.9, p = 0.03) were significantly associated with intervention preference. CONCLUSIONS: The interventions examined in this study were found to be acceptable to older adults, supporting future research examining their feasibility and effectiveness. PMID- 29463221 TI - Determinants of antenatal depression and postnatal depression in Australia. AB - BACKGROUND: Depression is a leading source of morbidity and health loss in Australian women. This study investigates the determinants of antenatal depressive symptoms and postnatal depressive symptoms in an Australian population, including people from culturally and linguistically diverse (CALD) backgrounds. METHOD: The study used a retrospective cohort of mothers of all live births in public health facilities in 2014 (N = 17,564) within South Western Sydney Local Health District and Sydney Local Health District in New South Wales, Australia. Prevalence of antenatal and postnatal depressive symptoms were estimated for the cohort. Multivariate logistic regression models were conducted to investigate the sociodemographic, psychological and health service determinants of antenatal and postnatal depressive symptoms, measured using the Edinburgh Postnatal Depression Scale (EPDS). RESULTS: The prevalence of antenatal and postnatal depressive symptoms was 6.2% and 3.3% of the cohort, respectively. Significant risk factors for maternal depressive symptoms during pregnancy were, a lack of partner support, history of intimate partner violence, being from the CALD population and low socioeconomic status. Self-reported antenatal depressive symptoms were strongly associated with postnatal depressive symptoms. Risk factors for postnatal depressive symptoms were similar to those for antenatal depressive symptoms, as well as assisted delivery. CONCLUSION: Factors relating to demographic and psychosocial disadvantage were associated with subsequent antenatal and postnatal depressive symptoms in New South Wales, Australia. Our study suggests that screening for probable depression and timely referral for expert assessment of at-risk mothers may be an effective strategy to improve maternal mental health outcomes. PMID- 29463222 TI - Filtration based assessment of CTCs and CellSearch(r) based assessment are both powerful predictors of prognosis for metastatic breast cancer patients. AB - BACKGROUND: The assessment of circulating tumor cells (CTCs) has been shown to enable monitoring of treatment response and early detection of metastatic breast cancer (MBC) recurrence. The aim of this study was to compare a well-established CTC detection method based on immunomagnetic isolation with a new, filtration based platform. METHODS: In this prospective study, two 7.5 ml blood draws were obtained from 60 MBC patients and CTC enumeration was assessed using both the CellSearch(r) and the newly developed filtration-based platform. We analyzed the correlation of CTC-positivity between both methods and their ability to predict prognosis. Overall survival (OS) was calculated and Kaplan-Meier curves were estimated with thresholds of >=1 and >=5 detected CTCs. RESULTS: The CTC positivity rate of the CellSearch(r) system was 56.7% and of the filtration-based platform 66.7%. There was a high correlation of CTC enumeration obtained with both methods. The OS for patients without detected CTCs, regardless of the method used, was significantly higher compared to patients with one or more CTCs (p < 0.001). The median OS of patients with no CTCs vs. >= 1 CTC assessed by CellSearch(r) was 1.83 years (95% CI: 1.63-2.02) vs. 0.74 years (95% CI: 0.51 1.52). If CTCs were detected by the filtration-based method the median OS times were 1.88 years (95% CI: 1.74-2.03) vs. 0.59 years (95% CI: 0.38-0.80). CONCLUSIONS: The newly established EpCAM independently filtration-based system is a suitable method to determine CTC counts for MBC patients. Our study confirms CTCs as being strong predictors of prognosis in our population of MBC patients. PMID- 29463223 TI - Breast cancer subtype discordance: impact on post-recurrence survival and potential treatment options. AB - BACKGROUND: Recent studies have shown that breast cancer subtype can change from the primary tumour to the recurrence. Discordance between primary and recurrent breast cancer has implications for further treatment and ultimately prognosis. The aim of the study was to determine the rate of change between primary and recurrence of breast cancer and to assess the impact of these changes on survival and potential treatment options. METHODS: Patient demographics were collected on those who underwent surgery for breast cancer between 2001 and 2014 and had a recurrence with biopsy results and pathology scoring of both the primary and recurrence. RESULTS: One hundred thirty two consecutive patients were included. There were 31 (23.5%) changes in subtype. Discordance occurred most frequently in luminal A breast cancer (n = 20), followed by triple negative (n = 4), luminal B (n = 3) and HER2 (n = 3). Patients who changed from luminal A to triple negative (n = 18) had a significantly worse post-recurrence survival (p < 0.05) with overall survival approaching significance (p = 0.064) compared to concordant luminal A cases (n = 46). Overall receptor discordance rates were: estrogen receptor 20.4% (n = 27), progesterone receptor 37.7% (n = 50) and HER2 3% (n = 4). Loss of estrogen receptor and progesterone receptor was more common than gain (21 vs. 6 (p = 0.04) and 44 vs. 6 (p = 0.01) respectively). Nine patients (6.8%) gained receptor status potentially impacting treatment options. CONCLUSION: Discordance in subtype and receptor status occurs between primary and recurrent breast cancer, ultimately affecting survival and potentially impacting treatment options. PMID- 29463224 TI - A spatiotemporal mixed model to assess the influence of environmental and socioeconomic factors on the incidence of hand, foot and mouth disease. AB - BACKGROUND: As a common infectious disease, hand, foot and mouth disease (HFMD) is affected by multiple environmental and socioeconomic factors, and its pathogenesis is complex. Furthermore, the transmission of HFMD is characterized by strong spatial clustering and autocorrelation, and the classical statistical approach may be biased without consideration of spatial autocorrelation. In this paper, we propose to embed spatial characteristics into a spatiotemporal additive model to improve HFMD incidence assessment. METHODS: Using incidence data (6439 samples from 137 monitoring district) for Shandong Province, China, along with meteorological, environmental and socioeconomic spatial and spatiotemporal covariate data, we proposed a spatiotemporal mixed model to estimate HFMD incidence. Geo-additive regression was used to model the non-linear effects of the covariates on the incidence risk of HFMD in univariate and multivariate models. Furthermore, the spatial effect was constructed to capture spatial autocorrelation at the sub-regional scale, and clusters (hotspots of high risk) were generated using spatiotemporal scanning statistics as a predictor. Linear and non-linear effects were compared to illustrate the usefulness of non-linear associations. Patterns of spatial effects and clusters were explored to illustrate the variation of the HFMD incidence across geographical sub-regions. To validate our approach, 10-fold cross-validation was conducted. RESULTS: The results showed that there were significant non-linear associations of the temporal index, spatiotemporal meteorological factors and spatial environmental and socioeconomic factors with HFMD incidence. Furthermore, there were strong spatial autocorrelation and clusters for the HFMD incidence. Spatiotemporal meteorological parameters, the normalized difference vegetation index (NDVI), the temporal index, spatiotemporal clustering and spatial effects played important roles as predictors in the multivariate models. Efron's cross-validation R2 of 0.83 was acquired using our approach. The spatial effect accounted for 23% of the R2, and notable patterns of the posterior spatial effect were captured. CONCLUSIONS: We developed a geo-additive mixed spatiotemporal model to assess the influence of meteorological, environmental and socioeconomic factors on HFMD incidence and explored spatiotemporal patterns of such incidence. Our approach achieved a competitive performance in cross-validation and revealed strong spatial patterns for the HFMD incidence rate, illustrating important implications for the epidemiology of HFMD. PMID- 29463225 TI - Glycolysis is essential for chemoresistance induced by transient receptor potential channel C5 in colorectal cancer. AB - BACKGROUND: Elevated intracellular Ca2+ ([Ca2+] i ) level could lead to [Ca2+] i overload and promote apoptosis via different pathways. In our previously study, up-regulated expression of transient receptor potential canonical channel (TRPC5) was proven to increase [Ca2+] i level, and resulted in chemoresistance whereas not apoptosis in human colorectal cancer (CRC) cells. The ATP-dependent homeostatic maintenance of resting [Ca2+] i should be important in this process. Increased glycolysis was found to be an important adenosine triphosphate (ATP) source in cancer. This study aimed to explore the potential mechanism of aerobic glycolysis in transient receptor potential channel TRPC5 induced chemoresistance. METHODS: In this study, we examined glucose transporter 1 (GLUT1) expression, glucose consumption and celluar ATP production to determine glycolytic activity. Real-time PCR and western blot were analyzed to determine TRPC5 expression at the mRNA and protein levels in human CRC cells (HCT-8, LoVo), and fluorouracil (5-Fu) resistant CRC cells (HCT-8/5-Fu, LoVo/5-Fu). 3-bromopyruvate (3-BP) and 2-Deoxy-D glucose (2DG) were used to inhibit glycolysis. Glycolytic activity, intracellular Ca2+ ([Ca2+] i ) and the half maximal inhibitory concentration of 5-Fu (5-Fu IC50) were measured. Western blot was analyzed to determine cleaved Caspase-3 protein level. Flow cytometry was performed to detect the apoptosis rates. Immunohistochemistry staining was performed to determine TRPC5 and GLUT1 expression level in human CRC tissues. RESULTS: Overproduced of TRPC5 and increased glycolysis were found in HCT-8/5-Fu and LoVo/5-Fu than in HCT-8 and LoVo cells. Compared to HCT-8 cells, the HCT-8/5-Fu cells showed higher [Ca2+] i levels which decreased after treated with TRPC5-specific shRNA. Furthemore, inhibition of glycolysis resulted in decreased ATP production, elevation of [Ca2+] i level and cleaved caspase-3, increased apoptotic cells rate, and a remarkable reversal of 5-Fu resistance in HCT-8/5-Fu cells, while showed no effect in HCT-8 cells. BAPTA-AM, a [Ca2+] i chelator, could reduce the elevation of cleaved caspase-3 and increased apoptotic cells rate due to glycolysis inhibition. Advanced CRC patients with high expression of TRPC5/GLUT1 displayed poorer chemotherapy outcome, and notably, the significant association between high TRPC5 expression and chemoresistance is GLUT1 expression level dependent. CONCLUSIONS: We demonstrated the essential role of glycolysis in TRPC5 induced chemoresistance in human CRC cells via maintaining [Ca2+] i homeostasis. PMID- 29463226 TI - Acquired distance esotropia associated with myopia in the young adult. AB - BACKGROUND: To describe the clinical features of acquired progressive esotropia, with a larger angle at distance than near, associated with myopia in young adults. METHODS: Eleven adults (ages ranging from 18 to 37 years) with constant or intermittent horizontal diplopia at distance were recruited. Subjective refraction, ocular alignment, fusional amplitudes and horizontal eye movements were measured at distance and near. RESULTS: Distance esotropia varied from 20 to 60 prism diopters (PD). At near, the esotropic deviation ranged from 10 to 30 PD. Spherical equivalents (SE) of the right eye ranged from - 3.50 to - 8.25 diopters (D) while SE of the left eye ranged from - 0.375 to - 7.25 D. Ten of the eleven patients presented with constant diplopia at distance. Horizontal ductions and versions were full in all patients. The pathological report of seven patients who underwent lateral rectus resection showed that there were no muscle fibres, but rather, collagenous fibres. CONCLUSIONS: This unusual sub-type of strabismus is a benign entity with slow progression that can occur in young adults with myopia. The cause of this condition is still unknown, and may be related to long periods of near work. PMID- 29463227 TI - Evaluating different breast tumor progression models using screening data. AB - BACKGROUND: Mammography screening is used to detect breast cancer at an early treatable stage, reducing breast cancer mortality. Traditionally, breast cancer has been seen as a disease with only progressive lesions, and here we examine the validity of this assumption by testing if incidence levels after introducing mammography screening can be reproduced assuming only progressive tumors. METHODS: Breast cancer incidence data 1990-2009 obtained from the initially screened Norwegian counties (Akershus, Oslo, Rogaland and Hordaland) was included, covering the time-period before, during and after the introduction of mammography screening. From 1996 women aged 50-69 were invited for biennial public screening. Using estimates of tumor growth and screening sensitivity based on pre-screening and prevalence screening data (1990-1998), we simulated incidence levels during the following period (1999-2009). RESULTS: The simulated incidence levels during the period with repeated screenings were markedly below the observed levels. The results were robust to changes in model parameters. Adjusting for hormone replacement therapy use, we obtained levels closer to the observed levels. However, there was still a marked gap, and only by assuming some tumors that undergo regressive changes or enter a markedly less detectable state, was our model able to reproduce the observed incidence levels. CONCLUSIONS: Models with strictly progressive tumors are only able to partly explain the changes in incidence levels observed after screening introduction in the initially screened Norwegian counties. More complex explanations than a time shift in detection of future clinical cancers seem to be needed to reproduce the incidence trends, questioning the basis for many over-diagnosis calculations. As data are not randomized, similar studies in other populations are wanted to exclude effect of unknown confounders. PMID- 29463228 TI - Preliminary qualification of a novel, hypoxic-based radiologic signature for trans-arterial chemoembolization in hepatocellular carcinoma. AB - BACKGROUND: Survival advantage following trans-arterial chemoembolization (TACE) is variable in patients with hepatocellular carcinoma (HCC). We combined pre-TACE radiologic features to derive a novel prognostic signature in HCC. METHODS: A multi-institutional dataset of 98 patients was generated from two retrospective cohorts from United Kingdom (65%) and Italy (36%). The prognostic impact of a number baseline imaging parameters was assessed and factors significant on univariate analysis were combined to create a novel radiologic signature on multivariable analyses predictive of overall survival (OS) following TACE. RESULTS: Median OS was 15.4 months. Tumour size > 7 cm (p < 0.001), intra-tumour necrosis (ITN) (p = 0.02) and arterial ectatic neovascularisation (AEN) (p = 0.03) emerged as individual prognostic factors together with radiologic response (p < 0.001) and elevated alpha-fetoprotein (AFP) (p = 0.01). Combination of tumour size > 7 cm, ITN and AEN identified patients with poor prognosis (p < 0.001). CONCLUSIONS: We identified a coherent signature based on commonly available imaging biomarkers likely to be reflective of differential patterns of relative hypoxia and neovascularisation. Large tumours displaying AEN and ITN are characterised by a shorter survival after TACE. PMID- 29463229 TI - Metastatic cardiac tumors: from clinical presentation through diagnosis to treatment. AB - BACKGROUND: To evaluate the prevalence of metastatic tumors involving the myocardium and study their presentation in order to increase awareness to their existence. METHODS: Pathological reports from Sheba Medical Center (Israel, January 1, 2010 through December 31, 2015) and medical records from The Institute for Cardiovascular Diseases of Vojvodina, Sremska Kamenica (Serbia, 23 years period) were screened for cases of metastatic cardiac tumors. Medical, radiological and pathological data of identified cases was retrieved and reviewed. RESULTS: Out of thousands of registered cardiac surgeries we found less than a dozen cases of metastatic cardiac tumors classified as melanoma, carcinomas of lung, colon and kidney and sarcomas of uterine origin. We found that metastatic cardiac tumors comprised 15.8% of all the cardiac tumors. CONCLUSIONS: Metastatic cardiac tumors are extremely rare. As new diagnostic technologies and improved survival of oncological patients may increase the incidence of metastatic cardiac tumors in the future, awareness to their existence and knowledge of their presentation are key factors in their timely recognition. PMID- 29463230 TI - Vendor-based restrictions on pesticide sales to prevent pesticide self-poisoning a pilot study. AB - BACKGROUND: In South Asia, up to 20% of people ingesting pesticides for self poisoning purchase the pesticide from a shop with the sole intention of self harm. Individuals who are intoxicated with alcohol and/or non-farmers represent 72% of such high-risk individuals. We aimed to test the feasibility and acceptability of vendor-based restrictions on pesticide sales for such high-risk individuals. METHODS: We conducted a pilot study in 14 (rural = 7, urban = 7) pesticide shops in Anuradhapura District of Sri Lanka. A two-hour training program was delivered to 28 pesticide vendors; the aim of the training was to help vendors recognize and respond to customers at high risk of pesticide self poisoning. Knowledge and attitudes of vendors towards preventing access to pesticides for self-poisoning at baseline and in a three month follow-up was evaluated by questionnaire. Vendors were interviewed to explore the practice skills taught in the training and their assessment of the program. RESULTS: The scores of knowledge and attitudes of the vendors significantly increased by 23% (95% CI 15%-32%, p < 0.001) and by 16% (95% CI 9%-23%, p < 0.001) respectively in the follow-up. Fifteen (60%) vendors reported refusing sell pesticides to a high risk person (non-farmer or intoxicated person) in the follow-up compared to three (12%) at baseline. Vendors reported that they were aware from community feedback that they had prevented at least seven suicide attempts. On four identified occasions, vendors in urban shops had been unable to recognize the self-harming intention of customers who then ingested the pesticide. Only 2 (8%) vendors were dissatisfied with the training and 23 (92%) said they would recommend it to other vendors. CONCLUSIONS: Our study suggests that vendor-based sales restriction in regions with high rates of self-poisoning has the potential to reduce access to pesticides for self-poisoning. A large-scale study of the effectiveness and sustainability of this approach is needed. PMID- 29463231 TI - Prevalence and correlates of non-adherence to immunosuppressants and to health behaviours in patients after kidney transplantation in Brazil - the ADHERE BRAZIL multicentre study: a cross-sectional study protocol. AB - BACKGROUND: Non-adherence to immunosuppressive therapy is a prevalent risk factor for poor clinical and after kidney transplantation (KT), and has contributed to the lack of improvement in long-term graft survival over the past decade. Understanding the multilevel correlates and risk factors of non-adherence is crucial to determine the optimal level for planning interventions, namely at the patient, health care provider, KT centre, and health care system level. Brazil, having the largest public transplantation program in the world and with regional differences regarding access to health services and service implementation, is in a unique position to study this multilevel approach. Therefore, the Adhere Brazil Study (ADHERE BRAZIL) was designed to assess the prevalence and variability of non-adherence to immunosuppressants and to health behaviours among adult KT recipients in Brazil, and to assess the multilevel correlates of non-adherence to immunosuppressive medication. We describe the rationale, design, and methodology of the ADHERE BRAZIL study. METHODS/DESIGN: This is an observational, cross sectional, multicentre study that includes 20 Brazilian KT centres. A stratified sampling approach is used, based on strata, with the following characteristics considered: geographical region and transplant activity (number of KTs per year). A random sample of patients (proportional to the size of the centre within each stratum) is selected from each centre. The prevalence of different health behaviours is assessed through self-report. The assessment of multilevel correlates of non-adherence is guided by the ecological model that considers factors at the level of the patient, health-care professional, and transplant centre, using established instruments or instruments developed for this study. Data will be collected over an 18-month period, with information obtained during the regular follow-up visits to the transplant outpatient clinic and directly entered into the Research Electronic Data Capture (RedCap) system. Data entry is performed by a trained professional who is part of the transplant team. The data collection began in December 2015. DISCUSSION: This multicentre study is the first to evaluate multilevel correlates of non-adherence in KT patients and will provide a reliable estimate of non-adherence in Brazilian KT patients.

AB - BACKGROUND: RNA-binding proteins (RBPs) play vital roles in many processes in the cell. Different RBPs bind RNA with different sequence and structure specificities. While sequence specificities for a large set of 205 RBPs have been reported through the RNAcompete compendium, structure specificities are known for only a small fraction. The main limitation lies in the design of the RNAcompete technology, which tests RBP binding against unstructured RNA probes, making it difficult to infer structural preferences from these data. We recently developed RCK, an algorithm to infer sequence and structural binding models from RNAcompete data. The set of binding models enables, for the first time, a large-scale assessment of RNA structure in the RBPome. RESULTS: We re-validate and uncover the role of RNA structure in the RPBome through novel analysis of the largest scale dataset to date. First, we show that RNA structure exists in presumably unstructured RNA probes and that its variability is correlated with RNA-binding. Second, we examine the structural binding preferences of RBPs and discover an overall preference to bind RNA loops. Third, we significantly improve protein binding prediction using RNA structure, both in vitro and in vivo. Lastly, we demonstrate that RNA structural binding preferences can be inferred for new proteins from solely their amino acid content. CONCLUSIONS: By counter intuitively demonstrating through our analysis that we can predict both the RNA structure of and RBP binding to these putatively unstructured RNAs, we transform a compendium of RNA-binding proteins into a valuable resource for structure-based binding models. We uncover the important role RNA structure plays in protein-RNA interaction for hundreds of RNA-binding proteins. PMID- 29463233 TI - Efficacy of a bivalent killed whole-cell cholera vaccine over five years: a re analysis of a cluster-randomized trial. AB - BACKGROUND: Oral cholera vaccine (OCV) is a feasible tool to prevent or mitigate cholera outbreaks. A better understanding of the vaccine's efficacy among different age groups and how rapidly its protection wanes could help guide vaccination policy. METHODS: To estimate the level and duration of OCV efficacy, we re-analyzed data from a previously published cluster-randomized, double-blind, placebo controlled trial with five years of follow-up. We used a Cox proportional hazards model and modeled the potentially time-dependent effect of age categories on both vaccine efficacy and risk of infection in the placebo group. In addition, we investigated the impact of an outbreak period on model estimation. RESULTS: Vaccine efficacy was 38% (95% CI: -2%,62%) for those vaccinated from ages 1 to under 5 years old, 85% (95% CI: 67%,93%) for those 5 to under 15 years, and 69% (95% CI: 49%,81%) for those vaccinated at ages 15 years and older. Among adult vaccinees, efficacy did not appear to wane during the trial, but there was insufficient data to assess the waning of efficacy among child vaccinees. CONCLUSIONS: Through this re-analysis we were able to detect a statistically significant difference in OCV efficacy when the vaccine was administered to children under 5 years old vs. children 5 years and older. The estimated efficacies are more similar to the previously published analysis based on the first two years of follow-up than the analysis based on all five years. TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT00289224. PMID- 29463234 TI - Tuberculosis treatment outcome and predictors in northern Ethiopian prisons: a five-year retrospective analysis. AB - BACKGROUND: The prison situations are notorious for causing interruptions of tuberculosis (TB) treatment and occurrence of unfavorable outcomes. In Ethiopian prisons, though TB treatment programs exist, treatment outcome results and factors contributing to unsuccessful outcome are not well documented. In this study, we assessed the treatment outcome of TB cases and identified risk factors for unsuccessful outcome in northern Ethiopian prisons. METHODS: A retrospective record review was conducted for all prisoners diagnosed with TB between September 2011 and August 2015. Outcome variables were defined following WHO guidelines. RESULTS: Out of the 496 patients, 11.5% were cured, 68% completed treatment, 2.5% were lost to follow-up, 1.6% were with a treatment failure, 1.4% died, and 15% were transferred out. All transferred out or released prisoners were not appropriately linked to health facilities and might be lost to treatment follow up. The overall treatment success rate (TSR) of the 5 years was 94% among the patients who were not transferred out. The odds of unsuccessful outcome were 4.68 times greater among re-treatment cases compared to the newly treated cases. The year of treatment was also associated with variations in TSR; those treated during the earlier year were more likely to have unsuccessful outcome. Sputum non conversion at the second-month check-up was strongly associated with unsuccessful outcome among the smear-positive cases. CONCLUSIONS: The mean TSR of the prisoners in the study prisons was quite satisfactory when gauged against the target level set by the End TB Strategy. However, the lack of appropriate linkage and tracking systems for those prisoners transferred or released before their treatment completion would have a negative implication for the national TB control program as such patients might interrupt their treatment and develop drug resistant TB. Being in a re-treatment regimen and sputum non-conversion at the second-month check-up were significantly associated with unsuccessful treatment outcome among the all forms of and smear-positive TB cases, respectively. PMID- 29463235 TI - Glucose, lipids and gamma-glutamyl transferase measured before prostate cancer diagnosis and secondly diagnosed primary tumours: a prospective study in the Swedish AMORIS cohort. AB - BACKGROUND: Improvements in detection and treatment of prostate cancer (PCa) translate into more men living with PCa, who are therefore potentially at risk of a secondly diagnosed primary tumour (SDPTs). Little is known about potential biochemical mechanisms linking PCa with the occurrence of SDPTs. The current study aims to investigate serum biomarkers of glucose and lipid metabolism and gamma-glutamyl transferase (GGT) measured prior to PCa diagnosis and their association with the occurrence of SDPTS. METHODS: From the Swedish AMORIS cohort, we selected all men diagnosed with PCa between 1996 and 2011, with at least one of the five biomarkers of interest (glucose, fructosamine, triglycerides, total cholesterol (TC), GGT) measured on average 16 years before PCa diagnosis (n = 10,791). Multivariate Cox proportional hazards models were used to determine hazard ratios (HR) for risk of SDPTs (overall and subtypes) by levels of the five biomarkers. Effect modification of treatment was assessed. RESULTS: 811 SDPTS were diagnosed during a median follow-up time of 5 years. Elevated levels of triglycerides (HR: 1.37, 95%CI: 1.17-1.60), TC (HR: 1.22, 95%CI: 1.04-1.42) and GGT (HR: 1.32, 95%CI: 1.02-1.71) were associated with an increased risk of SDPTs. Risk of SDPTs subtypes varied by biomarkers. CONCLUSION: Elevated levels of biomarkers of lipid metabolism and GGT measured prior to PCa diagnosis were associated with an increased risk of SDPTs, suggesting a potential common biochemical background for development of PCa and SDPTs. PMID- 29463236 TI - Rapid symptomatic relief of HER2-positive gastric cancer leptomeningeal carcinomatosis with lapatinib, trastuzumab and capecitabine: a case report. AB - BACKGROUND: Gastric cancer patients with widespread metastasis, especially meningeal metastases, have an extremely prognosis and limited therapeutic choices. CASE PRESENTATION: We reported the case of a 39-year-old male patient with HER2-positive gastric cancer with bone and meningeal metastases. He presented with multiple bone metastases and received 3 cycles of docetaxel plus S1. However, he complained with headache and imaging examinations revealed leptomeningeal carcinomatosis. FISH revealed that tumor cells in the cerebrospinal fluid were HER-positive. Herceptin was added to the regimen, but the symptoms were not relieved, the patient suffered from dizziness and nausea. The chemotherapy regimen was switched d to lapatinib (orally at 1250 mg/day, every day), capecitabine (orally at 1000 mg/m2, bid for 2 weeks, followed by a 1 week rest interval, as 1 cycle) and Herceptin (390 mg/3 weeks). After 3 weeks of the new treatment, all the symptoms relieved. The clinical complete response was maintained for 3 months. CONCLUSIONS: Lapatinib/Capecitabine combination therapy is an alternative treatment strategy for leptomeningeal carcinomatosis of HER2 positive gastric cancer in which trastuzumab and/or chemotherapy essentially has no effect. PMID- 29463237 TI - Inhibition of autophagy sensitizes cancer cells to Photofrin-based photodynamic therapy. AB - BACKGROUND: Accumulating evidence suggest that autophagy plays a pivotal role in various anticancer therapies, including photodynamic therapy (PDT), acting as a pro-death or pro-survival mechanism in a context-dependent manner. Therefore, we aimed to determine the role of autophagy in Photofrin-based PDT. METHODS: In vitro cytotoxic/cytostatic effects of PDT were evaluated with crystal violet cell viability assay. Autophagy induction was analyzed by immunoblotting and immunofluorescence using anti-LC3 antibody. Autophagy was inhibited by shRNA mediated ATG5 knockdown or CRISPR/Cas9-mediated ATG5 knockout. Apoptosis was assessed by flow cytometry analysis of propidium iodide and anexin V-positive cells as well as by detection of cleaved PARP and caspase 3 proteins using immunoblotting. Protein carbonylation was evaluated by the 2,4 dinitrophenylhydrazine (DNPH) method. RESULTS: Photofrin-PDT leads to robust autophagy induction in two cancer cell lines, Hela and MCF-7. shRNA-mediated knockdown of ATG5 only partially blocks autophagic response and only marginally affects the sensitivity of Hela and MCF-7 cells to PDT. ATG5 knockout in HeLa cell line utilizing CRISPR/Cas9 genome editing results in increased PDT-mediated cytotoxicity, which is accompanied by an enhanced apoptotic response and increased accumulation of carbonylated proteins. CONCLUSIONS: Altogether, these observations imply that autophagy contributes to Photofrin-PDT resistance by enabling clearance of carbonylated and other damaged proteins. Therefore, autophagy inhibition may serve as a strategy to improve PDT efficacy. PMID- 29463238 TI - Characterization and heterologous expression of the neoabyssomicin/abyssomicin biosynthetic gene cluster from Streptomyces koyangensis SCSIO 5802. AB - BACKGROUND: The deep-sea-derived microbe Streptomyces koyangensis SCSIO 5802 produces neoabyssomicins A-B (1-2) and abyssomicins 2 (3) and 4 (4). Neoabyssomicin A (1) augments human immunodeficiency virus-1 (HIV-1) replication whereas abyssomicin 2 (3) selectively reactivates latent HIV and is also active against Gram-positive pathogens including methicillin-resistant Staphylococcus aureus (MRSA). Structurally, neoabyssomicins A-B constitute a new subtype within the abyssomicin family and feature unique structural traits characteristic of extremely interesting biosynthetic transformations. RESULTS: In this work, the biosynthetic gene cluster (BGC) for the neoabyssomicins and abyssomicins, composed of 28 opening reading frames, was identified in S. koyangensis SCSIO 5802, and its role in neoabyssomicin/abyssomicin biosynthesis was confirmed via gene inactivation and heterologous expression experiments. Bioinformatics and genomics analyses enabled us to propose a biosynthetic pathway for neoabyssomicin/abyssomicin biosynthesis. Similarly, a protective export system by which both types of compounds are secreted from the S. koyangensis producer was identified, as was a four-component ABC transporter-based import system central to neoabyssomicin/abyssomicin biosynthesis. Furthermore, two regulatory genes, abmI and abmH, were unambiguously shown to be positive regulators of neoabyssomicin/abyssomicin biosynthesis. Consistent with their roles as positive regulatory genes, the overexpression of abmI and abmH (independent of each other) was shown to improve neoabyssomicin/abyssomicin titers. CONCLUSIONS: These studies provide new insight into the biosynthesis of the abyssomicin class of natural products, and highlight important exploitable features of its BGC for future efforts. Elucidation of the neoabyssomicin/abyssomicin BGC now enables combinatorial biosynthetic initiatives aimed at improving both the titers and pharmaceutical properties of these important natural products-based drug leads. PMID- 29463239 TI - Spatial modelling of malaria cases associated with environmental factors in South Sumatra, Indonesia. AB - BACKGROUND: Malaria, a parasitic infection, is a life-threatening disease in South Sumatra Province, Indonesia. This study aimed to investigate the spatial association between malaria occurrence and environmental risk factors. METHODS: The number of confirmed malaria cases was analysed for the year 2013 from the routine reporting of the Provincial Health Office of South Sumatra. The cases were spread over 436 out of 1613 villages. Six potential ecological predictors of malaria cases were analysed in the different regions using ordinary least square (OLS) and geographically weighted regression (GWR). The global pattern and spatial variability of associations between malaria cases and the selected potential ecological predictors was explored. RESULTS: The importance of different environmental and geographic parameters for malaria was shown at global and village-level in South Sumatra, Indonesia. The independent variables altitude, distance from forest, and rainfall in global OLS were significantly associated with malaria cases. However, as shown by GWR model and in line with recent reviews, the relationship between malaria and environmental factors in South Sumatra strongly varied spatially in different regions. CONCLUSIONS: A more in-depth understanding of local ecological factors influencing malaria disease as shown in present study may not only be useful for developing sustainable regional malaria control programmes, but can also benefit malaria elimination efforts at village level. PMID- 29463240 TI - Patient's and health care provider's perspectives on music therapy in palliative care - an integrative review. AB - BACKGROUND: The use of music as therapy in multidisciplinary end-of-life care dates back to the 1970s and nowadays music therapy (MT) is one of the most frequently used complementary therapy in in-patient palliative care in the US. However existing research investigated music therapy's potential impact mainly from one perspective, referring to either a quantitative or qualitative paradigm. The aim of this review is to provide an overview of the users' and providers' perspectives on music therapy in palliative care within one research article. METHODS: A systematic literature search was conducted using several databases supplemented with a hand-search of journals between November 1978 and December 2016. Inclusion criteria were: Music therapy with adults in palliative care conducted by a certified music therapist. Both quantitative and qualitative studies in English, German or a Scandinavian language published in peer reviewed journals were included. We aimed to identify and discuss the perspectives of both patients and health care providers on music therapy's impact in palliative care to forward a comprehensive understanding of it's effectiveness, benefits and limitations. We investigated themes mentioned by patients within qualitative studies, as well as commonly chosen outcome measures in quantitative research. A qualitative approach utilizing inductive content analysis was carried out to analyze and categorize the data. RESULTS: Twelve articles, reporting on nine quantitative and three qualitative research studies were included. Seven out of the nine quantitative studies investigated pain as an outcome. All of the included quantitative studies reported positive effects of the music therapy. Patients themselves associated MT with the expression of positive as well as challenging emotions and increased well-being. An overarching theme in both types of research is a psycho-physiological change through music therapy. CONCLUSIONS: Both quantitative as well as qualitative research showed positive changes in psycho-physiological well-being. The integration of the users' and providers' perspectives within future research applicable for example in mixed-methods designs is recommended. PMID- 29463242 TI - Overproduction, purification, and characterization of nanosized polyphosphate bodies from Synechococcus sp. PCC 7002. AB - BACKGROUND: Inorganic polyphosphate bodies (PPB) have recently been linked to a variety of functions in mammalian cells. To improve the yield of PPB from Synechococcus sp. PCC 7002 and characterize its form, in this study, a recombinant plasmid containing a polyphosphate kinase (ppk) gene was generated and transformed into Synechococcus sp. PCC 7002. RESULTS: PPB separated by Sephadex G-100 was characterized and added to polarized human intestinal epithelial (Caco-2) cells, and the absorption effect was assessed. The ppk gene was stably expressed by induction with 1 MUM nickel, and the resulting PPB yield from Synechococcus sp. PCC 7002 cells increased by 89.66%. Transmission electron microscopy and dynamic light scattering analyses showed that PPB from these cells were nanosized, ranging from a few to approximately 100 nanometres in diameter. PPB can be taken up by Caco-2 cells and are mainly distributed around lipid droplets. CONCLUSIONS: We determined that PPB can be overproduced in Synechococcus sp. PCC 7002 and that the resulting PPB were well absorbed by Caco 2 cells. Microalgae provide a promising "cell factory" for PPB production. PMID- 29463241 TI - Decreasing proportion of Anopheles darlingi biting outdoors between long-lasting insecticidal net distributions in peri-Iquitos, Amazonian Peru. AB - BACKGROUND: In Loreto Department, Peru, a successful 2005-2010 malaria control programme (known as PAMAFRO) included massive distribution of long-lasting insecticidal nets (LLINs). Additional local distribution of LLINs occurred in individual villages, but not between 2012 and 2015. A 2011-2012 study of the primary regional malaria vector Anopheles darlingi detected a trend of increased exophagy compared with pre-PAMAFRO behaviour. For the present study, An. darlingi were collected in three villages in Loreto in 2013-2015 to test two hypotheses: (1) that between LLIN distributions, An. darlingi reverted to pre-intervention biting behaviour; and, (2) that there are separate sub-populations of An. darlingi in Loreto with distinct biting behaviour. RESULTS: In 2013-2015 An. darlingi were collected by human landing catch during the rainy and dry seasons in the villages of Lupuna and Cahuide. The abundance of An. darlingi varied substantially across years, villages and time periods, and there was a twofold decrease in the ratio of exophagic:endophagic An. darlingi over the study period. Unexpectedly, there was evidence of a rainy season population decline in An. darlingi. Plasmodium-infected An. darlingi were detected indoors and outdoors throughout the night, and the monthly An. darlingi human biting rate was correlated with the number of malaria cases. Using nextRAD genotyping-by sequencing, 162 exophagic and endophagic An. darlingi collected at different times during the night were genotyped at 1021 loci. Based on model-based and non model-based analyses, all genotyped An. darlingi belonged to a homogeneous population, with no evidence for genetic differentiation by biting location or time. CONCLUSIONS: This study identified a decreasing proportion of exophagic An. darlingi in two villages in the years between LLIN distributions. As there was no evidence for genetic differentiation between endophagic and exophagic An. darlingi, this shift in biting behaviour may be the result of behavioural plasticity in An. darlingi, which shifted towards increased exophagy due to repellence by insecticides used to impregnate LLINs and subsequently reverted to increased endophagy as the nets aged. This study highlights the need to target vector control interventions to the biting behaviour of local vectors, which, like malaria risk, shows high temporal and spatial heterogeneity. PMID- 29463243 TI - Anacardic acid inhibits pancreatic cancer cell growth, and potentiates chemotherapeutic effect by Chmp1A - ATM - p53 signaling pathway. AB - BACKGROUND: Pancreatic cancer is one of the leading causes of cancer related death and its incidence has risen steadily. Although anticancer drugs have been developed based on the new molecular findings, the drugs have produced unsatisfactory results due to toxicity and resistance. Thus, a complementary therapeutic intervention is urgently needed for pancreatic cancer patients. METHODS: The aim of this study was to assess the potential therapeutic effect of Anacardic acid on pancreatic cancer in vitro and elucidate its underlying mechanisms. Human pancreatic cancer cells were treated with Anacardic acid and assessed for the cytotoxic effect using MTT and spheroid formation assays. Using the same methods, the synergy between Anacardic acid and 5-Fluorouracil or Gemcitabine was determined. To elucidate the underlying molecular mechanisms, Western blot analysis and immunocytochemistry were performed on cancer cells treated with Anacardic acid alone or in combination with 5-Fluorouracil or Gemcitabine. Chromatin Modifying Protein 1A (Chmp1A), Ataxia Telangiectasia Mutated (ATM), and p53 were the primary signaling molecules examined. In addition, Chmp1A was silenced with shRNA to examine the necessity of Chmp1A for the anticancer effect of Anacardic acid, 5-Fluorouracil, or Gemcitabine. RESULTS: Anacardic acid induced an anticancer effect in pancreatic cancer cell lines in a dose dependent manner, and increased the cytotoxicity of 5-Fluorouracil or Gemcitabine in MTT cell viability assays. In spheroid formation assays, spheroids formed were smaller in size and in number upon Anacardic acid treatment compared to control. Mechanistically, Anacardic acid exerted its anticancer activity via the activation of Chmp1A, ATM, and p53. Interestingly, 5-Fluorouracil and Gemcitabine also induced an increase in Chmp1A protein level, suggesting that Chmp1A might mediate the cytotoxic action of chemotherapeutics. Silencing experiments indicate that Chmp1A is required for the action of Anacardic acid, but not for 5-Fluorouracil or Gemcitabine. CONCLUSIONS: Our data suggests that Anacardic Acid might be a promising complementary supplement to slow the initiation or progression of pancreatic cancer. PMID- 29463244 TI - A single-center retrospective study of factors related to the effects of intravenous glucocorticoid therapy in moderate-to-severe and active thyroid associated ophthalmopathy. AB - BACKGROUND: Intravenous glucocorticoids (ivGC) have been recommended as a first line treatment of moderate-to-severe and active thyroid-associated ophthalmopathy (TAO). However, not all patients are responsive to ivGC. The identification of potential factors used to predict their efficacy and the selection of suitable patients have both been lacking. METHODS: It was a single center retrospective study. Potential factors related to the effects of ivGC were analyzed using logistic regression in 90 consecutive patients with moderate-to-severe and active TAO, who received 4.5 g ivGC therapy. Response was defined as the achievement of at least three points of the overall response. RESULTS: Fifty-two (57.8%) patients showed a positive response to ivGC therapy. Significant correlations were observed between the effects of ivGC and pretreatment clinical activity score (CAS), duration of eye symptoms, and restoration of euthyroidism. The two latter factors were both independent. The duration of eye symptoms was negatively correlated with the effects of ivGC, with an odds ratio (OR) of 0.984 (p = 0.012). Restoration of euthyroidism (OR = 3.282, p = 0.039) and pretreatment CAS (OR = 1.653, p < 0.01) were both positively correlated with the effects of ivGC. The diagnostic accuracy of the duration of eye symptoms was <=13 months (p = 0.000), with a specificity of 76.9%, and sensitivity of 65.8%. The diagnostic accuracy of the pretreatment CAS was more than 2.5 (p = 0.000), with a specificity of 61.5% and sensitivity of 80.5%. Besides, a multi-variables prediction model were established as well, which was better in the forecasting aspect with an area under curve of 0.784 (p = 0.000). CONCLUSIONS: The duration of eye symptoms and restoration of euthyroidism are independent factors that are associated with the effects of ivGC. The following practical implications were inferred: firstly, the shorter the duration of eye symptoms, the more favorable the effects of ivGC therapy. Thus, prompt diagnosis and treatment (within 13 months) is important. Secondly, the restoration of euthyroidism improves the efficacy of ivGC. Thirdly, hope the multi-variables prediction model can be applied to clinical therapy in the future. PMID- 29463245 TI - Fatigue in chronically critically ill patients following intensive care - reliability and validity of the multidimensional fatigue inventory (MFI-20). AB - BACKGROUND: Fatigue often occurs as long-term complication in chronically critically ill (CCI) patients after prolonged intensive care treatment. The Multidimensional Fatigue Inventory (MFI-20) has been established as valid instrument to measure fatigue in a wide range of medical illnesses. Regarding the measurement of fatigue in CCI patients, the psychometric properties of the MFI-20 have not been investigated so far. Thus, the present study examines reliability and validity of the MFI-20 in CCI patients. METHODS: A convenience sample of n = 195 patients with Critical Illness Polyneuropathy (CIP) or Myopathy (CIM) were recruited via personal contact within four weeks (t1) following the transfer from acute care ICU to post-acute ICU at a large rehabilitation hospital. N = 113 (median age 61.1 yrs., 72.6% men) patients were again contacted via telephone three (t2) and six (t3) months following the transfer to post-acute ICU. The MFI 20, the Euro-Quality of Life (EQ-5D-3 L) and the Structured Clinical Interview for the Diagnostic and Statistical Manual of mental disorders DSM-IV (SCID-I) were applied within this prospective cohort study. RESULTS: The internal consistency Cronbach's alpha was adequate for the MFI-total and all but the subscale Reduced Motivation (RM) (range: .50-.91). Item-to-total correlations (range: .22-.80) indicated item redundancy for the subscale RM. Confirmatory Factor analyses (CFAs) revealed poor model fit for the original 5-factor model of the MFI-20 (t2/t3, Confirmatory Fit Index, CFI = .783/ .834; Tucker-Lewis Index, TLI = .751/ .809; Root Mean Square Error of Approximation, RMSEA = .112/ .103). Among the alternative models (1-, 2-, 3-factor models), the data best fit to a 3 factor solution summarizing the highly correlated factors General -/ Physical Fatigue/ Reduced Activity (GF/ PF/ RA) (t2/ t3, CFI = .878/ .896, TLI = .846/ .869, RMSEA = .089/ .085, 90% Confidence Interval .073-.104/ .066-.104). The MFI total score significantly correlated with the health-related quality of life (range: -.65-(-).66) and the diagnosis of major depression (range: .27-.37). CONCLUSIONS: In the present sample of CCI patients, a reliable and valid factor structure of the MFI-20 could not be ascertained. Especially the subscale RM should be revised. Since the factors GF, PF and RA cannot be separated from each other and the unclear factorial structure in the present sample of CCI patients, the MFI-20 is not recommended for use in this context. TRIAL REGISTRATION: German Clinical Trials Registration DRKS00003386 . Registered 13 December 2011, retrospectively registered. PMID- 29463247 TI - Hormonal and environmental signals guiding stomatal development. AB - Stomata are pores on plant epidermis that facilitate gas exchange and water evaporation between plants and the environment. Given the central role of stomata in photosynthesis and water-use efficiency, two vital events for plant growth, stomatal development is tightly controlled by a diverse range of signals. A family of peptide hormones regulates stomatal patterning and differentiation. In addition, plant hormones as well as numerous environmental cues influence the decision of whether to make stomata or not in distinct and complex manners. In this review, we summarize recent findings that reveal the mechanism of these three groups of signals in controlling stomatal formation, and discuss how these signals are integrated into the core stomatal development pathway. PMID- 29463248 TI - Lactate promotes specific differentiation in bovine granulosa cells depending on lactate uptake thus mimicking an early post-LH stage. AB - BACKGROUND: The LH-induced folliculo-luteal transformation is connected with alterations of the gene expression profile in cells of the granulosa layer. It has been described that hypoxic conditions occur during luteinization, thus favoring the formation of L-lactate within the follicle. Despite being a product of anaerobic respiration, L-lactate has been shown to act as a signaling molecule affecting gene expression in neuronal cells. During the present study, we tested the hypothesis that L-lactate may influence differentiation of follicular granulosa cells (GC). METHODS: In a bovine granulosa cell culture model effects of L- and D-lactate, of increased glucose concentrations and of the lactate transport inhibitor UK5099 were analyzed. Steroid hormone production was analyzed by RIA and the abundance of key transcripts was determined by quantitative real time RT-PCR. RESULTS: L-lactate decreased the production of estradiol and significantly affected selected genes of the folliculo-luteal transition as well as genes of the lactate metabolism. CYP19A1, FSHR, LHCGR were down-regulated, whereas RGS2, VNN2, PTX3, LDHA and lactate transporters were up-regulated. These effects could be partly or completely reversed by pre-treatment of the cells with UK5099. The non-metabolized enantiomer D-lactate had even more pronounced effects on gene expression, whereas increased glucose concentrations did not affect transcript abundance. CONCLUSIONS: In summary, our data suggest that L-lactate specifically alters physiological and molecular characteristics of GC. These effects critically depend on L-lactate uptake, but are not triggered by increased energy supply. Further, we could show that L-lactate has a positive feedback on the lactate metabolism. Therefore, we hypothesize that L-lactate acts as a signaling molecule in bovine and possibly other monovular species supporting differentiation during the folliculo-luteal transformation. PMID- 29463249 TI - Continued in vitro cefazolin susceptibility in methicillin-susceptible Staphylococcus aureus. AB - OBJECTIVES: In vitro trends of cefazolin and ceftriaxone susceptibilities from pediatric clinical isolates of methicillin-susceptible Staphylococcus aureus (MSSA) between 2011 and 2016 were analyzed for surveillance. METHODS: Our laboratory continues to use agar disk diffusion for staphylococcal susceptibilities applying Clinical Laboratory Standard Institute's 2012 breakpoints. RESULTS: A total of 3992 MSSA clinical isolates in the last 6 years were analyzed for their in vitro cefazolin and ceftriaxone susceptibilities. While all MSSA isolates exhibited cefazolin susceptibilities within the "susceptible" zone range, there have been a proportion of isolates with ceftriaxone susceptibilities falling in "intermediate" zones, ranging from 2.6% in 2011 to 8.3% in 2016. CONCLUSIONS: Cefazolin continues to be the recommended agent for MSSA treatment at our institution, reflected by the finding that only 2% (6/321) of patients who received ceftriaxone as definitive therapy for MSSA bacteremia during the study period. We have confirmed the cefoxitin-predicted MSSA susceptibility to cefazolin, but have found concerning drifts in ceftriaxone susceptibilities by continued in vitro monitoring over the last 6 years. PMID- 29463246 TI - Next-generation, personalised, model-based critical care medicine: a state-of-the art review of in silico virtual patient models, methods, and cohorts, and how to validation them. AB - Critical care, like many healthcare areas, is under a dual assault from significantly increasing demographic and economic pressures. Intensive care unit (ICU) patients are highly variable in response to treatment, and increasingly aging populations mean ICUs are under increasing demand and their cohorts are increasingly ill. Equally, patient expectations are growing, while the economic ability to deliver care to all is declining. Better, more productive care is thus the big challenge. One means to that end is personalised care designed to manage the significant inter- and intra-patient variability that makes the ICU patient difficult. Thus, moving from current "one size fits all" protocolised care to adaptive, model-based "one method fits all" personalised care could deliver the required step change in the quality, and simultaneously the productivity and cost, of care. Computer models of human physiology are a unique tool to personalise care, as they can couple clinical data with mathematical methods to create subject-specific models and virtual patients to design new, personalised and more optimal protocols, as well as to guide care in real-time. They rely on identifying time varying patient-specific parameters in the model that capture inter- and intra-patient variability, the difference between patients and the evolution of patient condition. Properly validated, virtual patients represent the real patients, and can be used in silico to test different protocols or interventions, or in real-time to guide care. Hence, the underlying models and methods create the foundation for next generation care, as well as a tool for safely and rapidly developing personalised treatment protocols over large virtual cohorts using virtual trials. This review examines the models and methods used to create virtual patients. Specifically, it presents the models types and structures used and the data required. It then covers how to validate the resulting virtual patients and trials, and how these virtual trials can help design and optimise clinical trial. Links between these models and higher order, more complex physiome models are also discussed. In each section, it explores the progress reported up to date, especially on core ICU therapies in glycemic, circulatory and mechanical ventilation management, where high cost and frequency of occurrence provide a significant opportunity for model-based methods to have measurable clinical and economic impact. The outcomes are readily generalised to other areas of medical care. PMID- 29463251 TI - Kidney autotransplantation after nephrectomy and work bench surgery as an ultimate approach to nephron-sparing surgery. AB - BACKGROUND: Kidney autotransplantation (KAT) is the ultimate approach for nephron sparing surgery. It is a rarely used method in renal tumor surgery today as minimal invasive and open techniques for nephron-sparing surgery improve constantly. In this publication, the complication rate and the long-term functional and oncological outcome at a single center are analyzed. METHODS: A prospectively constructed database of patients with renal tumors who underwent renal surgery was retrospectively analyzed to identify patients with KAT and describe surgical and oncological outcomes and to obtain long-term follow-up. Data collection included detailed surgical technique, complications (Clavian Dindo), and hospital stay, as well as functional and oncological outcome and long term follow-up. RESULTS: Between 1976 and 2013, 12 patients (median age 50.5 years) underwent KAT for highly complex renal masses: in five cases for complex renal cell carcinoma (RCC), five cases for complex upper urinary tract carcinoma (UTUC), one case for a renal metastasis, and one case for nephroblastoma. The nephrectomy or nephron-ureterectomy was performed open via a flank or transabdominal. The median surgical time was 360 min (range 270-490 min). Intraoperatively, six cases required blood transfusions (50%). Six patients (50%) developed significant postoperative complications (Clavian-Dindo > 2). In two patients, intermittent hemodialysis for delayed graft function (16.6%) was needed, and in six cases (50%), additional blood transfusions postoperatively were necessary. At discharge from hospital, all patients had functioning grafts. The median hospital stay was 29.5 days (range 18-35). At follow-up (median follow up of 83.5 +/- 40.7 months), six patients had died (50%)-all with functioning grafts (free from hemodialysis). In five cases, recurrence of primary tumor or metastatic disease was recorded. In four cases, the recurrent carcinoma could be resected; in detail, UTUC in three cases and one partial nephrectomy of the autotransplanted kidney was performed. One patient suffered from bone and lung metastasis. Two patients died finally tumor-related. Five patients (41.6%) are presently alive, without evidence of tumor relapse. One patient developed terminal renal failure requiring hemodialysis 105 months after autotransplantation. One additional patient was lost to follow-up; after 69 months, this patient had a functioning kidney and no evidence of disease recurrence at the last follow-up. A cumulative number of 1424 months without hemodialysis was gained for these 12 patients. In the literature to date, most KAT are performed in benign disease, with minor but frequent complication. Here, we report the largest series of KAT for malignant kidney tumors. The complication rates are similar, compared to the recently reported series for benign indications with an improved graft survival rate. Since KAT requires a complex and challenging surgical approach, it should be performed by experienced kidney transplant surgeons. CONCLUSION: In very complex cases involving renal tumors and multi-morbidity, patients should be counseled well before KAT is considered. At the same time, KAT should not be abandoned in these very rare cases, especially when a nephron-sparing approach is otherwise not feasible. KAT can maintain renal function and quality of life and extend expectancy of life. PMID- 29463250 TI - Grey matter volume in healthy and epileptic beagles using voxel-based morphometry - a pilot study. AB - BACKGROUND: One of the most common chronic neurological disorders in dogs is idiopathic epilepsy (IE) diagnosed as epilepsy without structural changes in the brain. In the current study the hypothesis should be proven that subtle grey matter changes occur in epileptic dogs. Therefore, magnetic resonance (MR) images of one dog breed (Beagles) were used to obtain an approximately uniform brain shape. Local differences in grey matter volume (GMV) were compared between 5 healthy Beagles and 10 Beagles with spontaneously recurrent seizures (5 dogs with IE and 5 dogs with structural epilepsy (SE)), using voxel-based morphometry (VBM). T1W images of all dogs were prepared using Amira 6.3.0 for brain extraction, FSL 4.1.8 for registration and SPM12 for realignment. After creation of tissue probability maps of cerebrospinal fluid, grey and white matter from control images to segment all extracted brains, GM templates for each group were constructed to normalize brain images for parametric statistical analysis, which was achieved using SPM12. RESULTS: Epileptic Beagles (IE and SE Beagles) displayed statistically significant reduced GMV in olfactory bulb, cingulate gyrus, hippocampus and cortex, especially in temporal and occipital lobes. Beagles with IE showed statistically significant decreased GMV in olfactory bulb, cortex of parietal and temporal lobe, hippocampus and cingulate gyrus, Beagles with SE mild statistically significant GMV reduction in temporal lobe (p < 0.05; family- wise error correction). CONCLUSION: These results suggest that, as reported in epileptic humans, focal reduction in GMV also occurs in epileptic dogs. Furthermore, the current study shows that VBM analysis represents an excellent method to detect GMV differences of the brain between a healthy dog group and dogs with epileptic syndrome, when MR images of one breed are used. PMID- 29463252 TI - Anti-methicillin-resistance Staphylococcus aureus (MRSA) compounds from Bauhinia kockiana Korth. And their mechanism of antibacterial activity. AB - BACKGROUND: Bauhinia kockiana originates from Peninsular Malaysia and it is grown as a garden ornamental plant. Our previous study reported that this plant exhibited fairly strong antioxidant and antimicrobial activities. This paper focused on the assessment of the antibacterial activity of B. kockiana towards methicillin-resistance Staphylococcus aureus (MRSA), to purify and to identify the antibacterial compounds, and to determine the mechanism of antibacterial activity. METHODS: Antibacterial activity of B. kockiana flower was evaluated qualitatively and quantitatively using disc diffusion assay and microbroth dilution method. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of extracts were examined. Phytochemical analysis was performed to determine the classes of phytochemicals in the extracts. Bioactivity guided isolation was employed to purify the antibacterial agents and identified via various spectroscopy methods. Scanning electron microscopy (SEM) technique was used to evaluate the antibacterial mechanism of extract and compounds isolated. RESULTS: B. kockiana flower was found to exhibit fairly strong antibacterial activity towards both strains of MRSA bacteria used, MIC varies from 62.5-250 MUg/mL. Tannins and flavonoids have been detected in the phytochemical analysis. Gallic acid and its ester derivatives purified from ethyl acetate extract could inhibit MRSA at 250-500 MUg/mL. SEM revealed that the cells have undergone plasmolysis upon treatment with the extract and compounds. CONCLUSION: Tannins and polyphenols are the antibacterial components towards MRSA in B. kockiana. Massive leakage of the cell content observed in treated cells showed that the phytochemicals have changed the properties of the cell membranes. Amphiphilic nature of the compounds exhibited the antibacterial activity towards MRSA via three stages: (1) cell membrane attachment; (2) cell membrane fluidity modification; and (3) cell membrane structure disruption. PMID- 29463253 TI - Evaluation of health resource utilization efficiency in community health centers of Jiangsu Province, China. AB - BACKGROUND: While the demand for health services keep escalating at the grass roots or rural areas of China, a substantial portion of healthcare resources remain stagnant in the more developed cities and this has entrenched health inequity in many parts of China. At its conception, China's Deepen Medical Reform started in 2012 was intended to flush out possible disparities and promote a more equitable and efficient distribution of healthcare resources. Nearly half a decade of this reform, there are uncertainties as to whether the attainment of the objectives of the reform is in sight. METHODS: Using a hybrid of panel data analysis and an augmented data envelopment analysis (DEA), we model human resources, material, finance to determine their technical and scale efficiency to comprehensively evaluate the transverse and longitudinal allocation efficiency of community health resources in Jiangsu Province. RESULTS: We observed that the Deepen Medical Reform in China has led to an increase concern to ensure efficient allocation of community health resources by health policy makers in the province. This has led to greater efficiency in health resource allocation in Jiangsu in general but serious regional or municipal disparities still exist. Using the DEA model, we note that the output from the Community Health Centers does not commensurate with the substantial resources (human resources, materials, and financial) invested in them. We further observe that the case is worst in less developed Northern parts of Jiangsu Province. CONCLUSIONS: The government of Jiangsu Province could improve the efficiency of health resource allocation by improving the community health service system, rationalizing the allocation of health personnel, optimizing the allocation of material resources, and enhancing the level of health of financial resource allocation.

PMID- 29463254 TI - Spinacia oleracea extract attenuates disease progression and sub-chondral bone changes in monosodium iodoacetate-induced osteoarthritis in rats. AB - BACKGROUND: Spinacia oleracea is an important dietary vegetable in India and throughout the world and has many beneficial effects. It is cultivated globally. However, its effect on osteoarthritis that mainly targets the cartilage cells remains unknown. In this study we aimed to evaluate the anti-osteoarthritic and chondro-protective effects of SOE on chemically induced osteoarthritis (OA). METHODS: OA was induced by intra-patellar injection of monosodium iodoacetate (MIA) at the knee joint in rats. SOE was then given orally at 250 and 500 mg.kg- 1 day- 1 doses for 28 days to these rats. Anti-osteoarthritic potential of SOE was evaluated by micro-CT, mRNA and protein expression of pro-inflammatory and chondrogenic genes, clinically relevant biomarker's and behavioural experiments. RESULTS: In vitro cell free and cell based assays indicated that SOE acts as a strong anti-oxidant and an anti-inflammatory agent. Histological analysis of knee joints at the end of the experiment by safranin-o and toluidine blue staining established its protective effect. Radiological data corroborated the findings with improvement in the joint space and irregularity of the articular and atrophied femoral condyles and tibial plateau. Micro-CT analysis of sub-chondral bone indicated that SOE had the ability to mitigate OA effects by increasing bone volume to tissue volume (BV/TV) which resulted in decrease of trabecular pattern factor (Tb.Pf) by more than 200%. SOE stimulated chondrogenic marker gene expression with reduction in pro-inflammatory markers. Purified compounds isolated from SOE exhibited increased Sox-9 and Col-II protein expression in articular chondrocytes. Serum and urine analysis indicated that SOE had the potential to down-regulate glutathione S-transferase (GST) activity, clinical markers of osteoarthritis like cartilage oligometric matrix protein (COMP) and CTX-II. Overall, this led to a significant improvement in locomotion and balancing activity in rats as assessed by Open-field and Rota rod test. CONCLUSION: On the basis of in vitro and in vivo experiments performed with Spinacea oleracea extract we can deduce that SOE has the ability to alleviate the MIA induced deleterious effects. PMID- 29463256 TI - Developing the National Knowledge Platform in India: a policy and institutional analysis. AB - BACKGROUND: The importance of strong engagement between researchers and decision makers in the improvement of health systems is increasingly being recognised in low- and middle-income countries (LMICs). In 2013, in India, the Ministry of Health and Family Welfare began exploring the formation of a National Knowledge Platform (NKP) for guiding and supporting public health and health systems research in the country. The development of the NKP represents an important opportunity to enhance the linkage between policy-makers and researchers from the health policy and systems research field in India. However, the development process also reflects the highly complex reality of policy-making in the Indian health sector. Our objective is to provide insight into the policy-making process for establishing a health sector knowledge platform in India, and in doing so, to analyse the enabling contextual factors, the interests and actions of stakeholders, and the varying institutional arrangements explored in the development of the NKP. METHODS: We used a qualitative case study methodology, conducting 16 in-depth interviews and reviewing 42 documents. We utilised General Thematic Analysis to analyse our data. Our research team combined perspectives from both outsiders (independent researchers with no prior or current involvement with the policy) and insiders (researchers involved in the policy-making process). RESULTS: We found that enabling contextual factors, and a combination of government and non-governmental stakeholders with core interests in public health and health systems, were able to gain considerable momentum in moving the idea for the NKP forward. However, complex evidence-to-policy processes in the Indian health sector resulted in complications in determining the right institutional arrangement for the platform. Establishing the appropriate balance between legitimacy and independence, as well as frequent changes in institutional leadership, were found to be additional issues that stakeholders contended with in building the NKP. CONCLUSION: As interest in platforms linking health sector policy-makers and researchers grows in LMICs, our findings may allow stakeholders to learn from the Indian experience thus far, and to anticipate some of the facilitators and barriers that could potentially arise in establishing such mechanisms. PMID- 29463257 TI - Cerium oxide and barium sulfate nanoparticle inhalation affects gene expression in alveolar epithelial cells type II. AB - BACKGROUND: Understanding the molecular mechanisms of nanomaterial interacting with cellular systems is important for appropriate risk assessment. The identification of early biomarkers for potential (sub-)chronic effects of nanoparticles provides a promising approach towards cost-intensive and animal consuming long-term studies. As part of a 90-day inhalation toxicity study with CeO2 NM-212 and BaSO4 NM-220 the present investigations on gene expression and immunohistochemistry should reveal details on underlying mechanisms of pulmonary effects. The role of alveolar epithelial cells type II (AEII cells) is focused since its contribution to defense against inhaled particles and potentially resulting adverse effects is assumed. Low dose levels should help to specify particle-related events, including inflammation and oxidative stress. RESULTS: Rats were exposed to clean air, 0.1, 0.3, 1.0, and 3.0 mg/m3 CeO2 NM-212 or 50.0 mg/m3 BaSO4 NM-220 and the expression of 391 genes was analyzed in AEII cells after one, 28 and 90 days exposure. A total number of 34 genes was regulated, most of them related to inflammatory mediators. Marked changes in gene expression were measured for Ccl2, Ccl7, Ccl17, Ccl22, Ccl3, Ccl4, Il-1alpha, Il-1beta, and Il-1rn (inflammation), Lpo and Noxo1 (oxidative stress), and Mmp12 (inflammation/lung cancer). Genes related to genotoxicity and apoptosis did not display marked regulation. Although gene expression was less affected by BaSO4 compared to CeO2 the gene pattern showed great overlap. Gene expression was further analyzed in liver and kidney tissue showing inflammatory responses in both organs and marked downregulation of oxidative stress related genes in the kidney. Increases in the amount of Ce were measured in liver but not in kidney tissue. Investigation of selected genes on protein level revealed increased Ccl2 in bronchoalveolar lavage of exposed animals and increased Lpo and Mmp12 in the alveolar epithelia. CONCLUSION: AEII cells contribute to CeO2 nanoparticle caused inflammatory and oxidative stress reactions in the respiratory tract by the release of related mediators. Effects of BaSO4 exposure are low. However, overlap between both substances were detected and support identification of potential early biomarkers for nanoparticle effects on the respiratory system. Signs for long-term effects need to be further evaluated by comparison to a respective exposure setting. PMID- 29463259 TI - Climatic fluctuations and malaria transmission dynamics, prior to elimination, in Guna Yala, Republica de Panama. AB - BACKGROUND: Malaria has historically been entrenched in indigenous populations of the Republica de Panama. This scenario occurs despite the fact that successful methods for malaria elimination were developed during the creation of the Panama Canal. Today, most malaria cases in the Republica de Panama affect the Gunas, an indigenous group, which mainly live in autonomous regions of eastern Panama. Over recent decades several malaria outbreaks have affected the Gunas, and one hypothesis is that such outbreaks could have been exacerbated by climate change, especially by anomalous weather patterns driven by the EL Nino Southern Oscillation (ENSO). RESULTS: Monthly malaria cases in Guna Yala (1998-2016) were autocorrelated up to 2 months of lag, likely reflecting parasite transmission cycles between humans and mosquitoes, and cyclically for periods of 4 months that might reflect relapses of Plasmodium vivax, the dominant malaria parasite transmitted in Panama. Moreover, malaria case number was positively associated (P < 0.05) with rainfall (7 months of lag), and negatively with the El Nino 4 index (15 months of lag) and the Normalized Difference Vegetation Index, NDVI (8 months of lag), the sign and magnitude of these associations likely related to the impacts of weather patterns and vegetation on the ecology of Anopheles albimanus, the main malaria vector in Guna Yala. Interannual cycles, of approximately 4-year periods, in monthly malaria case numbers were associated with the El Nino 4 index, a climatic index associated with weather and vegetation dynamics in Guna Yala at seasonal and interannual time scales. CONCLUSION: The results showed that ENSO, rainfall and NDVI were associated with the number of malaria cases in Guna Yala during the study period. These results highlight the vulnerability of Guna populations to malaria, an infection sensitive to climate change, and call for further studies about weather impacts on malaria vector ecology, as well as the association of malaria vectors with Gunas paying attention to their socio economic conditions of poverty and cultural differences as an ethnic minority. PMID- 29463258 TI - The association between subgroups of MRI findings identified with latent class analysis and low back pain in 40-year-old Danes. AB - BACKGROUND: Research into the clinical importance of spinal MRI findings in patients with low back pain (LBP) has primarily focused on single imaging findings, such as Modic changes or disc degeneration, and found only weak associations with the presence of pain. However, numerous MRI findings almost always co-exist in the lumbar spine and are often present at more than one lumbar level. It is possible that multiple MRI findings are more strongly associated with LBP than single MRI findings. Latent Class Analysis is a statistical method that has recently been tested and found useful for identifying latent classes (subgroups) of MRI findings within multivariable datasets. The purpose of this study was to investigate the association between subgroups of MRI findings and the presence of LBP in people from the general population. METHODS: To identify subgroups of lumbar MRI findings with potential clinical relevance, Latent Class Analysis was initially performed on a clinical dataset of 631 patients seeking care for LBP. Subsequently, 412 participants in a general population cohort (the 'Backs on Funen' project) were statistically allocated to those existing subgroups by Latent Class Analysis, matching their MRI findings at a segmental level. The subgroups containing MRI findings from the general population were then organised into hypothetical pathways of degeneration and the association between subgroups in the pathways and the presence of LBP was tested using exact logistic regression. RESULTS: Six subgroups were identified in the clinical dataset and the data from the general population cohort fitted the subgroups well, with a median posterior probability of 93%-100%. These six subgroups described two pathways of increasing degeneration on upper (L1-L3) and lower (L4 L5) lumbar levels. An association with LBP was found for the subgroups describing severe and multiple degenerative MRI findings at the lower lumbar levels but none of the other subgroups were associated with LBP. CONCLUSION: Although MRI findings are common in asymptomatic people and the association between single MRI findings and LBP is often weak, our results suggest that subgroups of multiple and severe lumbar MRI findings have a stronger association with LBP than those with milder degrees of degeneration. PMID- 29463260 TI - Multifunctionalized biocatalytic P22 nanoreactor for combinatory treatment of ER+ breast cancer. AB - BACKGROUND: Tamoxifen is the standard endocrine therapy for breast cancers, which require metabolic activation by cytochrome P450 enzymes (CYP). However, the lower and variable concentrations of CYP activity at the tumor remain major bottlenecks for the efficient treatment, causing severe side-effects. Combination nanotherapy has gained much recent attention for cancer treatment as it reduces the drug associated toxicity without affecting the therapeutic response. RESULTS: Here we show the modular design of P22 bacteriophage virus-like particles for nanoscale integration of virus-driven enzyme prodrug therapy and photodynamic therapy. These virus capsids carrying CYP activity at the core are decorated with photosensitizer and targeting moiety at the surface for effective combinatory treatment. The estradiol-functionalized nanoparticles are recognized and internalized into ER+ breast tumor cells increasing the intracellular CYP activity and showing the ability to produce reactive oxygen species (ROS) upon UV365 nm irradiation. The generated ROS in synergy with enzymatic activity drastically enhanced the tamoxifen sensitivity in vitro, strongly inhibiting tumor cells. CONCLUSIONS: This work clearly demonstrated that the targeted combinatory treatment using multifunctional biocatalytic P22 represents the effective nanotherapeutics for ER+ breast cancer. PMID- 29463261 TI - HMGB2 is associated with malignancy and regulates Warburg effect by targeting LDHB and FBP1 in breast cancer. AB - BACKGROUND: High-mobility group box 2 (HMGB2) is implicated in tumorigenesis in various cancers. However, the clinical significance of HMGB2 signaling in human breast cancer progression remains unknown. METHODS: We investigated HMGB2 expression in 185 cases of primary breast cancer and matched normal breast tissue specimens, and explored the underlying mechanisms of altered HMGB2 expression as well as the impact of this altered expression on breast cancer growth and on aerobic glycolysis using in vitro and animal models of breast cancer. RESULTS: HMGB2 was more highly expressed in tumor-cell nuclei of breast cancer cells than in the adjacent normal breast tissues (P < 0.05). Higher HMGB2 expression correlated with larger tumor size (P = 0.003) and advanced tumor stage (P = 0.033). A Cox proportional hazards model revealed that HMGB2 expression was an independent prognostic factor for breast cancer after radical resection (P < 0.05). Experimentally, knockdown of HMGB2 expression by stable transfected shRNA significantly decreased the growth and glycolysis of breast cancer cells both in vitro and in mouse models. Mechanically, promotion of breast cancer progression by HMGB2 directly and significantly correlated with activation of LDHB expression and inactivation of FBP1 expression. CONCLUSIONS: These results disclose a novel role for HMGB2 in reprogramming the metabolic process in breast cancer cells by targeting LDHB and FBP1 and provide potential prognostic predictors for breast cancer patients.

PMID- 29463262 TI - Potential role of insulin receptor isoforms and IGF receptors in plaque instability of human and experimental atherosclerosis. AB - BACKGROUND: Clinical complications associated with atherosclerotic plaques arise from luminal obstruction due to plaque growth or destabilization leading to rupture. We previously demonstrated that overexpression of insulin receptor isoform A (IRA) and insulin-like growth factor-I receptor (IGF-IR) confers a proliferative and migratory advantage to vascular smooth muscle cells (VSMCs) promoting plaque growth in early stages of atherosclerosis. However, the role of insulin receptor (IR) isoforms, IGF-IR or insulin-like growth factor-II receptor (IGF-IIR) in VSMCs apoptosis during advanced atherosclerosis remains unclear. METHODS: We evaluated IR isoforms expression in human carotid atherosclerotic plaques by consecutive immunoprecipitations of insulin receptor isoform B (IRB) and IRA. Western blot analysis was performed to measure IGF-IR, IGF-IIR, and alpha-smooth muscle actin (alpha-SMA) expression in human plaques. The expression of those proteins, as well as the presence of apoptotic cells, was analyzed by immunohistochemistry in experimental atherosclerosis using BATIRKO; ApoE-/- mice, a model showing more aggravated vascular damage than ApoE-/- mice. Finally, apoptosis of VSMCs bearing IR (IRLoxP+/+ VSMCs), or not (IR-/- VSMCs), expressing IRA (IRA VSMCs) or expressing IRB (IRB VSMCs), was assessed by Western blot against cleaved caspase 3. RESULTS: We observed a significant decrease of IRA/IRB ratio in human complicated plaques as compared to non-complicated regions. Moreover, complicated plaques showed a reduced IGF-IR expression, an increased IGF-IIR expression, and lower levels of alpha-SMA indicating a loss of VSMCs. In experimental atherosclerosis, we found a significant decrease of IRA with an increased IRB expression in aorta from 24-week-old BATIRKO; ApoE-/- mice. Furthermore, atherosclerotic plaques from BATIRKO; ApoE-/- mice had less VSMCs content and higher number of apoptotic cells. In vitro experiments showed that IGF-IR inhibition by picropodophyllin induced apoptosis in VSMCs. Apoptosis induced by thapsigargin was lower in IR-/- VSMCs expressing higher IGF-IR levels as compared to IRLoxP+/+ VSMCs. Finally, IRB VSMCs are more prone to thapsigargin induced apoptosis than IRA or IRLoxP+/+ VSMCs. CONCLUSIONS: In advanced human atherosclerosis, a reduction of IRA/IRB ratio, decreased IGF-IR expression, or increased IGF-IIR may contribute to VSMCs apoptosis, promoting plaque instability and increasing the risk of plaque rupture and its clinical consequences. PMID- 29463264 TI - Using non-exceedance probabilities of policy-relevant malaria prevalence thresholds to identify areas of low transmission in Somalia. AB - BACKGROUND: Countries planning malaria elimination must adapt from sustaining universal control to targeted intervention and surveillance. Decisions to make this transition require interpretable information, including malaria parasite survey data. As transmission declines, observed parasite prevalence becomes highly heterogeneous with most communities reporting estimates close to zero. Absolute estimates of prevalence become hard to interpret as a measure of transmission intensity and suitable statistical methods are required to handle uncertainty of area-wide predictions that are programmatically relevant. METHODS: A spatio-temporal geostatistical binomial model for Plasmodium falciparum prevalence (PfPR) was developed using data from cross-sectional surveys conducted in Somalia in 2005, 2007-2011 and 2014. The fitted model was then used to generate maps of non-exceedance probabilities, i.e. the predictive probability that the region-wide population-weighted average PfPR for children between 2 and 10 years (PfPR2-10) lies below 1 and 5%. A comparison was carried out with the decision-making outcomes from those of standard approaches that ignore uncertainty in prevalence estimates. RESULTS: By 2010, most regions in Somalia were at least 70% likely to be below 5% PfPR2-10 and, by 2014, 17 regions were below 5% PfPR2-10 with a probability greater than 90%. Larger uncertainty is observed using a threshold of 1%. By 2011, only two regions were more than 90% likely of being < 1% PfPR2-10 and, by 2014, only three regions showed such low level of uncertainty. The use of non-exceedance probabilities indicated that there was weak evidence to classify 10 out of the 18 regions as < 1% in 2014, when a greater than 90% non-exceedance probability was required. CONCLUSION: Unlike standard approaches, non-exceedance probabilities of spatially modelled PfPR2-10 allow to quantify uncertainty of prevalence estimates in relation to policy relevant intervention thresholds, providing programmatically relevant metrics to make decisions on transitioning from sustained malaria control to strategies that encompass methods of malaria elimination. PMID- 29463265 TI - Fatty acids modulate the expression levels of key proteins for cholesterol absorption in Caco-2 monolayer. AB - BACKGROUND: Fatty acids have been shown to modulate intestinal cholesterol absorption in cells and animals, a process that is mediated by several transporter proteins. Of these proteins, Niemann-Pick C1-Like 1 (NPC1L1) is a major contributor to this process. The current study investigates the unknown mechanism by which fatty acids modulate cholesterol absorption. METHODS: We evaluated the effects of six fatty acids palmitic acid (PAM), oleic acid (OLA), linoleic acid (LNA), arachidonic acid (ARA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) on cholesterol uptake and transport in human enterocytes Caco-2 cells, and on the mRNA expression levels of NPC1L1, others proteins (ABCG5, ABCG8, ABCA1, ACAT2, MTP, Caveolin 1, Annexin-2) involved in cholesterol absorption, and SREBP-1 and SREBP-2 that are responsible for lipid metabolism. RESULTS: The polyunsaturated fatty acids (PUFAs), especially for EPA and DHA, dose-dependently inhibited cholesterol uptake and transport in Caco-2 monolayer, while saturated fatty acids (SFAs) and monounsaturated fatty acids (MUFAs) had no inhibitory effects. EPA and DHA inhibited cholesterol absorption in Caco-2 monolayer might be caused by down-regulating NPC1L1 mRNA and protein levels, which were associated with inhibition of SREBP-1/- 2 mRNA expression levels. CONCLUSION: Results from this study indicate that functional food containing high PUFAs may have potential therapeutic benefit to reduce cholesterol absorption. Further studies on this topic may provide approaches to control lipid metabolism and to promote health. PMID- 29463266 TI - Unresectable hepatic PEComa: a rare malignancy treated with stereotactic body radiation therapy (SBRT) followed by complete resection. AB - BACKGROUND: Perivascular epithelioid cell tumors (PEComas) are rare mesenchymal tumors occurring in various anatomic regions. Although diagnostic criteria and treatment management are not established, current treatment options consist of surgery and chemotherapy including mTOR inhibitors. Stereotactic body radiation therapy (SBRT) is a non-invasive ablative treatment which has shown excellent control rates for more common types of unresectable liver tumors and metastases. In this report we present a rare case of PEComa of the liver that was treated by stereotactic radiotherapy followed by resection. Staging and evaluation of treatment response was done by FDG-PET/CT. This case highlights the potential of SBRT as a neoadjuvant treatment even for rare liver malignancies. It is the first case of liver PEComa treated by SBRT and resection. CASE PRESENTATION: A 52-year old woman presented at an external hospital with abdominal pressure and pain in the right upper abdominal quadrant. A CT scan showed a 700 cm3 liver lesion in segment IV. In repeated biopsy in July 2015 histopathological workup showed a pleomorphic epitheloid tumor with small to medium sized cells expressing vimentin and melan-A while being negative for cytokeratin establishing the diagnosis of PEComa of the liver. To achieve high, ablative doses a stereotactic body radiotherapy (SBRT) technique was chosen consisting of 60Gy (biologically effective dose 105Gy) in 8 fractions of 7.5Gy. Radiotherapy planning was based on MRI resulting in a planning target volume (PTV) of 1944 cm3. Treatment toxicity was limited to a slight elevation of transaminases (grade 1 and 3). A complete resection was performed 21 weeks after radiotherapy confirmed by negative surgical margins. At last follow-up 21 months after therapy, MRI showed neither local nor distant tumor recurrence. The patient was in stable condition (ECOG 1) and without late radiation toxicity. CONCLUSIONS: This is the first documented case of liver PEComa treated by SBRT and resection. A favorable post-treatment course demonstrates that SBRT is a potential neoadjuvant treatment that is capable of reducing an inoperable rare liver tumor to a resectable lesion. PMID- 29463267 TI - Hippocampus-sparing radiotherapy using volumetric modulated arc therapy (VMAT) to the primary brain tumor: the result of dosimetric study and neurocognitive function assessment. AB - BACKGROUND: We hypothesized that hippocampal-sparing radiotherapy via volumetric modulated arc therapy (VMAT) could preserve the neurocognitive function (NCF) of patients with primary brain tumors treated with radiotherapy. METHODS: We reviewed data from patients with primary brain tumors who underwent hippocampal sparing brain radiotherapy via VMAT between February 2014 and December 2015. The optimization criteria for the contralateral hippocampus was a maximum dose (Dmax) of less than 17 Gy. For NCF evaluations, the Seoul Verbal Learning Test for total recall, delayed recall, and recognition (SVLT-TR, DR, and Recognition) was performed at baseline and at seven months after radiotherapy. RESULTS: A total of 26 patients underwent NCF testing seven months after radiotherapy. Their median age was 49.5 years (range 26-77 years), and 14 (53.8%) had grade III/IV tumors. The median Dmax to the contralateral hippocampus was 16.4 Gy (range 3.5-63.4). The median mean dose to the contralateral hippocampus, expressed as equivalent to a 2-Gy dose (EQD2/2), was 7.4 Gy2 (0.7-13.1). The mean relative changes in SVLT TR, SVLT-DR, and SVLT-Recognition at seven months compared to the baseline were - 7.7% (95% confidence interval [CI], - 19.6% to 4.2%), - 9.2% (95% CI, - 25.4% to 7.0%), and - 3.4% (- 12.7% to 5.8%), respectively. Two patients (7.7%) showed deteriorated NCF in the SVLT-TR and SVLT-DR, and three (11.5%) in the SVLT Recognition. The mean dose of the left hippocampus and bilateral hippocampi were significantly higher in patients showing deterioration of the SVLT-TR and SVLT Recognition than in those without deterioration. CONCLUSIONS: The contralateral hippocampus could be effectively spared in patients with primary brain tumor via VMAT to preserve the verbal memory function. Further investigation is needed to identify those patients who will most benefit from hippocampal-sparing radiotherapy of the primary brain tumor. PMID- 29463268 TI - Influence of coronary territory on flow profiles of saphenous vein grafts. AB - BACKGROUND: Differing perfusion of the left and right ventricular coronary territory may influence flow-profiles of saphenous vein grafts (SVGs). We compared flow parameters, measured by transit-time flowmetry (TTFM), in left- and right-sided SVGs during coronary artery by-pass grafting (CABG). METHODS: Routine TTFM measurements were obtained in 167 SVGs to the left territory (55%) and 134 SVGs to the right territory (total of 301 SVGs in 207 patients). The four standard TTFM parameters, [mean graft flow (MGF), pulsatility index (PI), percentage diastolic filling (%DF), and percentage backward flow (%BF)] were compared. Differences in flow parameters were also examined according to surgical technique (on- vs. off-pump). RESULTS: No significant difference between coronary territories was found for MGF, PI and %BF. However, a higher %DF was noted in left-sided SVGs in the overall cohort as well as in the on-pump (both p < 0.001) and the off-pump cohorts (p = 0.07). Further, a significantly higher %BF was found in SVGs performed off-pump to the left territory (1.2 +/- 2.5 vs. 2.3 +/- 3.0, p = 0.023). In a multivariate regression analysis, anastomosing a SVG to the left territory was weakly associated with higher PI (OR = 0.36, p = 0.026) and strongly associated with higher %DF (OR = 5.1, p < 0.001). No significant association was found for MGF, PI, %DF or %BF in either the on-pump nor the off pump cohorts. CONCLUSIONS: Although statistically significant, the established differences in TTFM parameters between left- and right-sided vein grafts were small and unlikely to be of clinical relevance. PMID- 29463269 TI - Telomere attrition in heart failure: a flow-FISH longitudinal analysis of circulating monocytes. AB - BACKGROUND: Cross-sectional investigations report shorter telomeres in patients with heart failure (HF); however, no studies describe telomere length (TL) trajectory and its relationship with HF progression. Here we aimed to investigate telomere shortening over time and its relationship to outcomes. METHODS: Our study cohort included 101 ambulatory patients with HF. Blood samples were collected at baseline (n = 101) and at the 1-year follow-up (n = 54). Using flow FISH analysis of circulating monocytes, we simultaneously measured three monocyte subsets-classical (CD14++CD16-), intermediate (CD14++CD16+), and nonclassical (CD14+CD16++)-and their respective TLs based on FITC-labeled PNA probe hybridization. The primary endpoints were all-cause death and the composite of all-cause death or HF-related hospitalization, assessed at 2.3 +/- 0.6 years. All statistical analyses were executed by using the SPSS 15.0 software, and included Student's t test and ANOVA with post hoc Scheffe analysis, Pearson or Spearman rho correlation and univariate Cox regression when applicable. RESULTS: We found high correlations between TL values of different monocyte subsets: CD14++CD16+ vs. CD14++CD16-, R = 0.95, p < 0.001; CD14++CD16+ vs. CD14+CD16++, R = 0.90, p < 0.001; and CD14++CD16- vs. CD14+CD16++, R = 0.89, p < 0.001. Mean monocyte TL exhibited significant attrition from baseline to the 1-year follow-up (11.1 +/- 3.3 vs. 8.3 +/- 2.1, p < 0.001). TL did not significantly differ between monocyte subsets at either sampling time-point (all p values > 0.1). Cox regression analyses did not indicate that TL or DeltaTL was associated with all-cause death or the composite endpoint. CONCLUSIONS: Overall, this longitudinal study demonstrated a ~ 22% reduction of TL in monocytes from ambulatory patients with HF within 1 year. TL and DeltaTL were not related to outcomes over long-term follow-up. PMID- 29463270 TI - The unfunded priorities: an evaluation of priority setting for noncommunicable disease control in Uganda. AB - BACKGROUND: The double burden of infectious diseases coupled with noncommunicable diseases poses unique challenges for priority setting and for achieving equitable action to address the major causes of disease burden in health systems already impacted by limited resources. Noncommunicable disease control is an important global health and development priority. However, there are challenges for translating this global priority into local priorities and action. The aim of this study was to evaluate the influence of national, sub-national and global factors on priority setting for noncommunicable disease control in Uganda and examine the extent to which priority setting was successful. METHODS: A mixed methods design that used the Kapiriri & Martin framework for evaluating priority setting in low income countries. The evaluation period was 2005-2015. Data collection included a document review (policy documents (n = 19); meeting minutes (n = 28)), media analysis (n = 114) and stakeholder interviews (n = 9). Data were analysed according to the Kapiriri & Martin (2010) framework. RESULTS: Priority setting for noncommunicable diseases was not entirely fair nor successful. While there were explicit processes that incorporated relevant criteria, evidence and wide stakeholder involvement, these criteria were not used systematically or consistently in the contemplation of noncommunicable diseases. There were insufficient resources for noncommunicable diseases, despite being a priority area. There were weaknesses in the priority setting institutions, and insufficient mechanisms to ensure accountability for decision-making. Priority setting was influenced by the priorities of major stakeholders (i.e. development assistance partners) which were not always aligned with national priorities. There were major delays in the implementation of noncommunicable disease-related priorities and in many cases, a failure to implement. CONCLUSIONS: This evaluation revealed the challenges that low income countries are grappling with in prioritizing noncommunicable diseases in the context of a double disease burden with limited resources. Strengthening local capacity for priority setting would help to support the development of sustainable and implementable noncommunicable disease-related priorities. Global support (i.e. aid) to low income countries for noncommunicable diseases must also catch up to align with NCDs as a global health priority. PMID- 29463271 TI - A simulation study on estimating biomarker-treatment interaction effects in randomized trials with prognostic variables. AB - BACKGROUND: To individualize treatment decisions based on patient characteristics, identification of an interaction between a biomarker and treatment is necessary. Often such potential interactions are analysed using data from randomized clinical trials intended for comparison of two treatments. Tests of interactions are often lacking statistical power and we investigated if and how a consideration of further prognostic variables can improve power and decrease the bias of estimated biomarker-treatment interactions in randomized clinical trials with time-to-event outcomes. METHODS: A simulation study was performed to assess how prognostic factors affect the estimate of the biomarker treatment interaction for a time-to-event outcome, when different approaches, like ignoring other prognostic factors, including all available covariates or using variable selection strategies, are applied. Different scenarios regarding the proportion of censored observations, the correlation structure between the covariate of interest and further potential prognostic variables, and the strength of the interaction were considered. RESULTS: The simulation study revealed that in a regression model for estimating a biomarker-treatment interaction, the probability of detecting a biomarker-treatment interaction can be increased by including prognostic variables that are associated with the outcome, and that the interaction estimate is biased when relevant prognostic variables are not considered. However, the probability of a false-positive finding increases if too many potential predictors are included or if variable selection is performed inadequately. CONCLUSIONS: We recommend undertaking an adequate literature search before data analysis to derive information about potential prognostic variables and to gain power for detecting true interaction effects and pre-specifying analyses to avoid selective reporting and increased false-positive rates. PMID- 29463272 TI - Colonic perineurioma (benign fibroblastic polyp): case report and review of the literature. AB - BACKGROUND: Colorectal perineuriomas are uncommon benign mucosal-based proliferations of mesenchymal cells that express perineurial markers, often associated with colonic crypts displaying a serrated/hyperplastic architecture. The vast majority of cases arise distal to the splenic flexure and have been described as sessile polyps. Using molecular analysis, BRAF mutations have been demonstrated in the serrated crypt epithelium. We report a new case of perineurioma presenting as a pedunculated polyp in the transverse colon, with prominent hemosiderin deposits in the uninvolved lamina propria that separated the perineurial proliferation from the surface epithelium, a previously unreported histological finding. By using immunohistochemistry, we demonstrated the presence of BRAF V600E mutated protein in the serrated crypt epithelium. In addition, a review of the literature on colorectal perineurioma is provided. CASE PRESENTATION: A 5 mm pedunculated polyp was removed from the transverse colon of a 42 year old man who presented with epigastric pain, weight loss and rectal bleeding. A proliferation of uniform plump spindled cells expanded the lamina propria and separated serrated colonic crypts. The epithelial component closely resembled microvesicular hyperplastic polyp. Immunohistochemical stains for epithelial membrane antigen (EMA), glucose transporter 1 (GLUT1) and collagen IV were positive in the stromal proliferation. A mutation-specific monoclonal antibody directed against BRAF V600E showed positive cytoplasmic staining in the serrated crypt epithelium but not in the perineurial proliferation. Conspicuous hemosiderin deposition was seen in the inflamed lamina propria between the perineurial proliferation and the surface epithelium. CONCLUSION: Although the majority of colorectal perineuriomas occur in the sigmoid colon and rectum and are described as sessile polyps, colorectal perineurioma can present as a pedunculated polyp proximal to the splenic flexure as described in this case. Conspicuous hemosiderin deposition can be seen in the superficial lamina propria. BRAF mutations are limited to the serrated crypt epithelium. PMID- 29463273 TI - Outcomes of oblique lateral interbody fusion for degenerative lumbar disease in patients under or over 65 years of age. AB - BACKGROUND: Oblique lateral interbody fusion (OLIF) offers the solution to problems of anterior lumbar interbody fusion (ALIF) and lateral lumbar interbody fusion (LLIF). However, OLIF technique for degenerative spinal diseases of elderly patients has been rarely reported. The objective of this study was to determine the clinical and radiological results of OLIF technique for degenerative spinal diseases in patients under or over 65 years of age. METHODS: Sixty-three patients who underwent OLIF procedure were enrolled, including 29 patients who were less than 65 years of age and 34 patients who were over 65 years of age. Fusion rate, change of disc height and lumbar lordotic angle, Numeric Rating Scale (NRS), return to daily activity, patient's satisfaction rate (PSR), and Oswestry disability index (ODI) were used to assess clinical and functional outcomes. RESULTS: The mean NRS scores for back and leg pain decreased, respectively, from 4.6 and 5.9 to 2.3 and 1.8 in the group A (less than 65 years) and from 4.5 and 6.8 to 2.6 and 2.2 in the group B (over 65 years) at the final follow-up period. The mean ODI scores improved from 48.4 to 24.0% in the group A and from 46.5 to 25.2% in the group B at the final follow-up period. In both groups, the NRS and ODI scores significantly changed preoperatively to postoperatively (p < 0.001). However, statistical analysis yielded no significant difference in postoperative NRS/ODI scores between two groups. In both groups, the changes in the disc height, segmental lordosis, and fusion rate between the preoperative and postoperative periods were significant. The amount of change between preoperative and postoperative disc height, segmental lordosis, and whole lumbar lordosis demonstrated significant intergroup differences (p < 0.05). Overall perioperative complications occurred in 8 of 29 (27.6%) patients in the group A and in 10 of 34 (29.4%) patients in the group B. In both groups, the major complication incidence was 0 and 3%, respectively. CONCLUSION: Although there was the slightly high incidence of complication associated with high rate of co-morbidities in elderly patients, OLIF for degenerative lumbar diseases in elderly patients showed favorable clinical and radiological outcomes. PMID- 29463274 TI - Along with its favorable prognostic role, CLCA2 inhibits growth and metastasis of nasopharyngeal carcinoma cells via inhibition of FAK/ERK signaling. AB - BACKGROUND: CLCA2 was reported as a tumor suppressor and disregulated in breast cancer. However, its function in tumor growth and metastasis in NPC has rarely been reported. In this study, we investigated the functional and molecular mechanisms by which CLCA2 influences NPC. METHODS: CLCA2 expression in human NPC cell lines and tissues was examined via real-time PCR (RT-PCR), Western blot and IHC. The biological roles of CLCA2 in proliferative, migration and invasion of NPC cell lines was evaluated in 5-8F, S18, S26 and SUNE-1 cells. Cell viability, migration and invasion were assessed in vitro by MTS, colony formation and transwell assay, respectively. CLCA2 in growth and metastasis of NPC were evaluated in vivo through NPC xenograft tumor growth, lung metastatic mice model and popliteal lymph node (LN) metastasis model. RESULTS: Overexpression of CLCA2 significantly decreased proliferation, migration and invasion of NPC cells. In contrast, knockdown of CLCA2 elicited the opposite effects. CLCA2 overexpression suppressed xenograft tumor growth and lung, popliteal lymph node (LN) metastasis in vivo. CLCA2 inhibited tumor metastasis through suppressing epithelial Mesenchymal transition (EMT) and in-activating FAK/ERK1/2 signaling pathway in NPC cells. Immunohistochemical staining of 143 NPC samples revealed that CLCA2 expression was an independent, favorable prognostic factor for overall survival and distant metastasis-free survival of patients. In addition, inhibition of FAK and ERK1/2 reversed CLCA2 silencing-induced tumor cell migration. Furthermore, inhibitors against chloride channels suppressed NPC cellular migration which could have been enhanced by the presence of CLCA2. CONCLUSION: CLCA2 suppress NPC proliferation, migration, invasion and epithelial-mesenchymal transition through inhibiting FAK/ERK signaling. PMID- 29463275 TI - Leukocyte telomere length in paediatric critical illness: effect of early parenteral nutrition. AB - BACKGROUND: Children who have suffered from critical illnesses that required treatment in a paediatric intensive care unit (PICU) have long-term physical and neurodevelopmental impairments. The mechanisms underlying this legacy remain largely unknown. In patients suffering from chronic diseases hallmarked by inflammation and oxidative stress, poor long-term outcome has been associated with shorter telomeres. Shortened telomeres have also been reported to result from excessive food consumption and/or unhealthy nutrition. We investigated whether critically ill children admitted to the PICU have shorter-than-normal telomeres, and whether early parenteral nutrition (PN) independently affects telomere length when adjusting for known determinants of telomere length. METHODS: Telomere length was quantified in leukocyte DNA from 342 healthy children and from 1148 patients who had been enrolled in the multicenter, randomised controlled trial (RCT), PEPaNIC. These patients were randomly allocated to initiation of PN within 24 h (early PN) or to withholding PN for one week in PICU (late PN). The impact of early PN versus late PN on the change in telomere length from the first to last PICU-day was investigated with multivariable linear regression analyses. RESULTS: Leukocyte telomeres were 6% shorter than normal upon PICU admission (median 1.625 (IQR 1.446-1.825) telomere/single-copy-gene ratio (T/S) units vs. 1.727 (1.547-1.915) T/S-units in healthy children (P < 0.0001)). Adjusted for potential baseline determinants and leukocyte composition, early PN was associated with telomere shortening during PICU stay as compared with late PN (estimate early versus late PN -0.021 T/S units, 95% CI -0.038; 0.004, P = 0.01). Other independent determinants of telomere length identified in this model were age, gender, baseline telomere length and fraction of neutrophils in the sample from which the DNA was extracted. Telomere shortening with early PN was independent of post randomisation factors affected by early PN, including longer length of PICU stay, larger amounts of insulin and higher risk of infection. CONCLUSIONS: Shorter than normal leukocyte telomeres are present in critically ill children admitted to the PICU. Early initiation of PN further shortened telomeres, an effect that was independent of other determinants. Whether such telomere-shortening predisposes to long-term consequences of paediatric critical illness should be further investigated in a prospective follow-up study.

PMID- 29463278 TI - Clinical and radiological effect of medialized cortical bone trajectory for lumbar pedicle screw fixation in patients with degenerative lumbar spondylolisthesis: study protocol for a randomized controlled trial (mPACT). AB - BACKGROUND: Spinal fusion with pedicle screw fixation represents the gold standard for lumbar degenerative disc disease with instability. Although it is an established technique, it is nevertheless an invasive intervention with high complication rates. Therefore, minimally invasive approaches have been developed, the medialized bilateral screw pedicel fixation (mPACT) being one of them. The study objective is to evaluate prospectively the efficacy and safety of the mPACT technique compared with the traditional trajectory for degenerative lumbar spondylolisthesis. METHODS/DESIGN: This is a single-center, randomized, controlled, parallel group, superiority trial. A total of 154 adult patients are allocated in a ratio of 1:1. Sample size and power calculation were performed to detect the minimal clinically important difference of 10%, with an expected standard deviation of 20% in the primary outcome parameter, the Oswestry Disability Index, with power of 80%, based on an assumed maximal dropout rate of 20%. Secondary outcome parameters include the EuroQoL 5-Dimension questionnaire, the Beck Depression Inventory, the painDETECT questionnaire and the "timed up and go" test. Furthermore, radiological and health economic outcomes will be evaluated. Follow up is performed until 5 years after surgery. Major inclusion criteria are lumbar degenerative spondylolisthesis with Meyerding grade I or II, which qualifies for decompression and fusion by medialised posterior screw placement with cortical trajectory (mPACT) or by a traditional trajectory for lumbar pedicle screw placement. DISCUSSION: This trial will contribute to the understanding of the short-term and long-term clinical and radiological postoperative course in patients with lumbar degenerative disc disease, in which the mPACT technique is used.

PMID- 29463279 TI - Evaluation of a Chlamydia trachomatis-specific, commercial, real-time PCR for use with ocular swabs. AB - BACKGROUND: Trachoma, the leading infectious cause of blindness worldwide, is caused by conjunctival Chlamydia trachomatis infection. Trachoma is diagnosed clinically by observation of conjunctival inflammation and/or scarring; however, there is evidence that monitoring C. trachomatis infection may be required for elimination programmes. There are many commercial and 'in-house' nucleic acid amplification tests for the detection of C. trachomatis DNA, but the majority have not been validated for use with ocular swabs. This study evaluated a commercial assay, the Fast-Track Vaginal swab kit, using conjunctival samples from trachoma-endemic areas. An objective, biostatistical-based method for binary classification of continuous PCR data was developed, to limit potential user-bias in diagnostic settings. METHODS: The Fast-Track Vaginal swab assay was run on 210 ocular swab samples from Guinea-Bissau and Tanzania. Fit of individual amplification curves to exponential or sigmoid models, derivative and second derivative of the curves and final fluorescence value were examined for utility in thresholding for determining positivity. The results from the Fast-Track Vaginal swab assay were evaluated against a commercial test (Amplicor CT/NG) and a non-commercial test (in-house droplet digital PCR), both of whose performance has previously been evaluated. RESULTS: Significant evidence of exponential amplification (R2 > 0.99) and final fluorescence > 0.15 were combined for thresholding. This objective approach identified a population of positive samples, however there were a subset of samples that amplified towards the end of the cycling protocol (at or later than 35 cycles), which were less clearly defined. The Fast-Track Vaginal swab assay showed good sensitivity against the commercial (95.71) and non-commercial (97.18) tests. Specificity was lower against both (90.00 and 96.55, respectively). CONCLUSIONS: This study defined a simple, automated protocol for binary classification of continuous, real-time qPCR data, for use in an end-point diagnostic test. This method identified a population of positive samples, however, as with manual thresholding, a subset of samples that amplified towards the end of the cycling program were less easily classified. When used with ocular swabs, the Fast-Track Vaginal swab assay had good sensitivity for C. trachomatis detection, but lower specificity than the commercial and non-commercial assays it was evaluated against, possibly leading to false positives. PMID- 29463280 TI - Prophylactic platelet transfusion prior to central venous catheter placement in patients with thrombocytopenia: study protocol for a randomised controlled trial. AB - BACKGROUND: Severe thrombocytopenia should be corrected by prophylactic platelet transfusion prior to central venous catheter (CVC) insertion, according to national and international guidelines. Even though correction is thought to prevent bleeding complications, evidence supporting the routine administration of prophylactic platelets is absent. Furthermore, platelet transfusion bears inherent risk. Since the introduction of ultrasound-guided CVC placement, bleeding complication rates have decreased. The objective of the current trial is, therefore, to demonstrate that omitting prophylactic platelet transfusion prior to CVC placement in severely thrombocytopenic patients is non-inferior compared to prophylactic platelet transfusion. METHODS/DESIGN: The PACER trial is an investigator-initiated, national, multicentre, single-blinded, randomised controlled, non-inferior, two-arm trial in haematologic and/or intensive care patients with a platelet count of between 10 and 50 * 109/L and an indication for CVC placement. Consecutive patients are randomly assigned to either receive 1 unit of platelet concentrate, or receive no prophylactic platelet transfusion prior to CVC insertion. The primary endpoint is WHO grades 2-4 bleeding. Secondary endpoints are any bleeding complication, costs, length of intensive care and hospital stay and transfusion requirements. DISCUSSION: This is the first prospective, randomised controlled trial powered to test the hypothesis of whether omitting forgoing platelet transfusion prior to central venous cannulation leads to an equal occurrence of clinical relevant bleeding complications in critically ill and haematologic patients with thrombocytopenia.

PMID- 29463281 TI - Soluble Abeta1-42 increases the heterogeneity in synaptic vesicle pool size among synapses by suppressing intersynaptic vesicle sharing. AB - Growing evidence has indicated that prefibrillar form of soluble amyloid beta (sAbeta1-42) is the major causative factor in the synaptic dysfunction associated with AD. The molecular changes leading to presynaptic dysfunction caused by sAbeta1-42, however, still remains elusive. Recently, we found that sAbeta1-42 inhibits chemically induced long-term potentiation-induced synaptogenesis by suppressing the intersynaptic vesicle trafficking through calcium (Ca2+) dependent hyperphosphorylation of synapsin and CaMKIV. However, it is still unclear how sAbeta1-42 increases intracellular Ca2+ that induces hyperphosphorylation of CaMKIV and synapsin, and what is the functional consequences of sAbeta1-42-induced defects in intersynaptic vesicle trafficking in physiological conditions. In this study, we showed that sAbeta1-42elevated intracellular Ca2+ through not only extracellular Ca2+ influx but also Ca2+ release from mitochondria. Surprisingly, without Ca2+ release from mitochondria, sAbeta1-42 failed to increase intracellular Ca2+ even in the presence of normal extracellular Ca2+. We further found that sAbeta1-42-induced mitochondria Ca2+ release alone sufficiently increased Serine 9 phosphorylation of synapsin. By blocking synaptic vesicle reallocation, sAbeta1-42 significantly increased heterogeneity of total synaptic vesicle pool size among synapses. Together, our results suggested that by disrupting the axonal vesicle trafficking, sAbeta1-42 disabled neurons to adjust synaptic pool sizes among synapses, which might prevent homeostatic rescaling in synaptic strength of individual neurons. PMID- 29463282 TI - Longitudinal study of age-specific pattern of coronavirus infection in Lyle's flying fox (Pteropus lylei) in Thailand. AB - BACKGROUND: Bats are natural reservoirs for several highly pathogenic and novel viruses including coronaviruses (CoVs) (mainly Alphacoronavirus and Betacoronavirus). Lyle's flying fox (Pteropus lylei)'s roosts and foraging sites are usually in the proximity to humans and animals. Knowledge about age-specific pattern of CoV infection in P. lylei, prevalence, and viral shedding at roosts and foraging sites may have an impact on infection-age-structure model to control CoV outbreak. METHODS: P. lylei bats were captured monthly during January December 2012 for detection of CoV at three areas in Chonburi province; two human dwellings, S1 and S2, where few fruit trees were located with an open pig farm, 0.6 km and 5.5 km away from the bat roost, S3. Nested RT-PCR of RNA-dependent RNA polymerase (RdRp) gene from rectal swabs was used for CoV detection. The strain of CoV was confirmed by sequencing and phylogenetic analysis. RESULTS: CoV infection was found in both juveniles and adult bats between May and October (January, in adults only and April, in juveniles only). Of total rectal swab positives (68/367, 18.5%), ratio was higher in bats captured at S1 (11/44, 25.0%) and S2 (35/99, 35.4%) foraging sites than at roost (S3) (22/224, 9.8%). Juveniles (forearm length <= 136 mm) were found with more CoV infection than adults at all three sites; S1 (9/24, 37.5% vs 2/20, 10%), S2 (22/49, 44.9% vs 13/50, 26.0%), and S3 (10/30, 33.3% vs 12/194, 6.2%). The average BCI of CoV infected bats was significantly lower than uninfected bats. No gender difference related to infection was found at the sites. Phylogenetic analysis of conserved RdRp gene revealed that the detected CoVs belonged to group D betacoronavirus (n = 64) and alphacoronavirus (n = 4). CONCLUSIONS: The fact that CoV infection and shedding was found in more juvenile than adult bats may suggest transmission from mother during peripartum period. Whether viral reactivation during parturition period or stress is responsible in maintaining transmission in the bat colony needs to be explored. PMID- 29463283 TI - Neonatal diagnosis of isolated absence of the right pulmonary artery: a case report and review of the literature. AB - BACKGROUND: Unilateral absence of the pulmonary artery (UAPA) is a rare congenital malformation often associated with other cardiac anomalies; however it may occur as an isolated lesion. Isolated absence of the right pulmonary artery is twice more frequent than that of the left pulmonary artery. Patients with isolated UAPA are usually asymptomatic at birth; thereafter they may develop a progression of symptoms such as exercise intolerance, dyspnea, chest pain, hemoptysis and recurrent pulmonary infections. As patients may remain asymptomatic or have vague symptoms, the diagnosis of isolated UAPA can be difficult to make in infancy. Indeed, most cases described in literature are adults. Due to the rarity of neonatal presentation, there is no consensus regarding the treatment of this malformation. CASE PRESENTATION: Herein, the case of a two-day-old term female infant, born after uneventful pregnancy, who required a cardiological assessment for a light murmur, is reported; an echocardiogram demonstrated an isolated unilateral absence of the right pulmonary artery, confirmed by means of magnetic resonance imaging (MRI) performed 1 month after child's birth. Besides this finding, MRI showed a slightly increased lumen and size of the main and left pulmonary arteries. The right lung was shown to be perfused by some systemic collateral arteries. In the absence of any other cardiovascular malformation, our patient did not need any treatment. As symptoms may occur later in life, a thorough clinical and cardiological follow up was immediately started. Three years later, she is still asymptomatic, showing adequate growth, without any sign of pulmonary hypertension. CONCLUSIONS: Isolated UAPA is a very rare malformation with a diverse clinical presentation. To the best of our knowledge, this is the second case of neonatal presentation of UAPA reported in literature to date. We believe that our case report supports the opinion that a prompt cardiological evaluation is needed whenever a newborn shows signs and/or symptoms of cardiorespiratory concern. Any missed neonatal diagnosis of UAPA may contribute to the later age at presentation, with resultant higher risk of morbidity and mortality and greater therapeutical difficulties. PMID- 29463284 TI - The potential role of HGF-MET signaling and autophagy in the war of Alectinib versus Crizotinib against ALK-positive NSCLC. AB - Non-small-cell lung cancer (NSCLC) is currently the leading cause of cancer related death. Accumulating evidences suggest that overcoming the therapeutic resistance in NSCLC is a big challenge. Recently, the outcomes of two independent phase 3 trials regarding Alectinib versus Crizotinib in ALK-positive NSCLC are encouraging. However, given the potential relevance of HGF-MET signaling and especially autophagy to the war against ALK-positive NSCLC between Alectinib and Crizotinib, it's too early to reach a convincing conclusion. Therefore, to further improve the therapeutic efficacy of ALK-positive NSCLC, this commentary highlights the negligence in design of relevant clinical trials, emphasizes the importance of molecular characteristics investigation, and discusses the prospect of combination therapy. PMID- 29463285 TI - Network modules uncover mechanisms of skeletal muscle dysfunction in COPD patients. AB - BACKGROUND: Chronic obstructive pulmonary disease (COPD) patients often show skeletal muscle dysfunction that has a prominent negative impact on prognosis. The study aims to further explore underlying mechanisms of skeletal muscle dysfunction as a characteristic systemic effect of COPD, potentially modifiable with preventive interventions (i.e. muscle training). The research analyzes network module associated pathways and evaluates the findings using independent measurements. METHODS: We characterized the transcriptionally active network modules of interacting proteins in the vastus lateralis of COPD patients (n = 15, FEV1 46 +/- 12% pred, age 68 +/- 7 years) and healthy sedentary controls (n = 12, age 65 +/- 9 years), at rest and after an 8-week endurance training program. Network modules were functionally evaluated using experimental data derived from the same study groups. RESULTS: At baseline, we identified four COPD specific network modules indicating abnormalities in creatinine metabolism, calcium homeostasis, oxidative stress and inflammatory responses, showing statistically significant associations with exercise capacity (VO2 peak, Watts peak, BODE index and blood lactate levels) (P < 0.05 each), but not with lung function (FEV1). Training-induced network modules displayed marked differences between COPD and controls. Healthy subjects specific training adaptations were significantly associated with cell bioenergetics (P < 0.05) which, in turn, showed strong relationships with training-induced plasma metabolomic changes; whereas, effects of training in COPD were constrained to muscle remodeling. CONCLUSION: In summary, altered muscle bioenergetics appears as the most striking finding, potentially driving other abnormal skeletal muscle responses.

PMID- 29463286 TI - Bronchopulmonary dysplasia: clinical aspects and preventive and therapeutic strategies. AB - BACKGROUND: Bronchopulmonary dysplasia (BPD) is the result of a complex process in which several prenatal and/or postnatal factors interfere with lower respiratory tract development, leading to a severe, lifelong disease. In this review, what is presently known regarding BPD pathogenesis, its impact on long term pulmonary morbidity and mortality and the available preventive and therapeutic strategies are discussed. MAIN BODY: Bronchopulmonary dysplasia is associated with persistent lung impairment later in life, significantly impacting health services because subjects with BPD have, in most cases, frequent respiratory diseases and reductions in quality of life and life expectancy. Prematurity per se is associated with an increased risk of long-term lung problems. However, in children with BPD, impairment of pulmonary structures and function is even greater, although the characterization of long-term outcomes of BPD is difficult because the adults presently available to study have received outdated treatment. Prenatal and postnatal preventive measures are extremely important to reduce the risk of BPD. CONCLUSION: Bronchopulmonary dysplasia is a respiratory condition that presently occurs in preterm neonates and can lead to chronic respiratory problems. Although knowledge about BPD pathogenesis has significantly increased in recent years, not all of the mechanisms that lead to lung damage are completely understood, which explains why therapeutic approaches that are theoretically effective have been only partly satisfactory or useless and, in some cases, potentially negative. However, prevention of prematurity, systematic use of nonaggressive ventilator measures, avoiding supraphysiologic oxygen exposure and administration of surfactant, caffeine and vitamin A can significantly reduce the risk of BPD development. Cell therapy is the most fascinating new measure to address the lung damage due to BPD. It is desirable that ongoing studies yield positive results to definitively solve a major clinical, social and economic problem. PMID- 29463287 TI - Weaved into the cultural fabric: a qualitative exploration of alcohol consumption during pregnancy among tribal women in Odisha, India. AB - BACKGROUND: Evidence-based research has documented the association between alcohol intake during pregnancy and increased risk of miscarriage, stillbirth and congenital birth defects. Alcohol consumption is a complex behavior whose origins lay in cultural norms and the social structure. In tribal communities in India, alcohol misuse among women is a public health problem. This study is intended to explore perceptions and beliefs among tribal women and the community towards alcohol consumption during pregnancy. METHODS: A qualitative study was conducted in a tribal-dominated district of Odisha, India. The WHO AUDIT tool was used to identify women who consumed alcohol during their pregnancies. In-depth interviews were conducted with 19 eligible women and 18 family members. Additionally, two focused group discussions were held with local community leaders and health workers. The data was transcribed, systematically coded and analyzed following the thematic framework approach. RESULTS: The findings suggest that a complex interplay of drivers contributes to the unrestricted intake of alcohol by pregnant women. This could be attributed to: a lack of social monitoring, easy access to alcohol, low alcohol literacy and alcohol's normative status in daily customs and traditions. Another contributing factor is a community-wide perception that home-made alcohol poses no ill effects. CONCLUSION: Alcohol consumption is deeply embedded in the daily rituals of indigenous tribal women. To address this issue, community counselling utilizing platforms of RMNCHA and VHND could be Ideal. A well-designed, culture-based intervention encompassing alcohol researchers, mental health specialists, public health workers and anthropologists is necessary. PMID- 29463288 TI - Reactive community-based self-administered treatment against residual malaria transmission: study protocol for a randomized controlled trial. AB - BACKGROUND: Systematic treatment of all individuals living in the same compound of a clinical malaria case may clear asymptomatic infections and possibly reduce malaria transmission, where this is focal. High and sustained coverage is extremely important and requires active community engagement. This study explores a community-based approach to treating malaria case contacts. METHODS/DESIGN: This is a cluster-randomized trial to determine whether, in low-transmission areas, treating individuals living in the same compound of a clinical malaria case with dihydroartemisinin-piperaquine can reduce parasite carriage and thus residual malaria transmission. Treatment will be administered through the local health system with the approach of encouraging community participation designed and monitored through formative research. The trial goal is to show that this approach can reduce in intervention villages the prevalence of Plasmodium falciparum infection toward the end of the malaria transmission season. DISCUSSION: Adherence and cooperation of the local communities are critical for the success of mass treatment campaigns aimed at reducing malaria transmission. By exploring community perceptions of the changing trends in malaria burden, existing health systems, and reaction to self-administered treatment, this study will develop and adapt a model for community engagement toward malaria elimination that is cost-effective and fits within the existing health system.

AB - BACKGROUND: Echovirus (E) 30 (E-30) meningitis is characterized by neuroinflammation involving immune cell pleocytosis at the protective barriers of the central nervous system (CNS). In this context, infection of the blood cerebrospinal fluid barrier (BCSFB), which has been demonstrated to be involved in enteroviral CNS pathogenesis, may affect the tight junction (TJ) and adherens junction (AJ) function and morphology. METHODS: We used an in vitro human choroid plexus epithelial (HIBCPP) cell model to investigate the effect of three clinical outbreak strains (13-311, 13-759, and 14-397) isolated in Germany in 2013, and compared them to E-30 Bastianni. Conducting transepithelial electrical resistance (TEER), paracellular dextran flux measurement, quantitative real-time polymerase chain reaction (qPCR), western blot, and immunofluorescence analysis, we investigated TJ and AJ function and morphology as well as strain-specific E-30 infection patterns. Additionally, transmission electron and focused ion beam microscopy electron microscopy (FIB-SEM) was used to evaluate the mode of leukocyte transmigration. Genome sequencing and phylogenetic analyses were performed to discriminate potential genetic differences among the outbreak strains. RESULTS: We observed a significant strain-dependent decrease in TEER with strains E-30 Bastianni and 13-311, whereas paracellular dextran flux was only affected by E-30 Bastianni. Despite strong similarities among the outbreak strains in replication characteristics and particle distribution, strain 13-311 was the only outbreak isolate revealing comparable disruptive effects on TJ (Zonula Occludens (ZO) 1 and occludin) and AJ (E-cadherin) morphology to E-30 Bastianni. Notwithstanding significant junctional alterations upon E-30 infection, we observed both para- and transcellular leukocyte migration across HIBCPP cells. Complete genome sequencing revealed differences between the strains analyzed, but no explicit correlation with the observed strain-dependent effects on HIBCPP cells was possible. CONCLUSION: The findings revealed distinct E-30 strain-specific effects on barrier integrity and junctional morphology. Despite E 30-induced barrier alterations leukocyte trafficking did not exclusively occur via the paracellular route. PMID- 29463290 TI - Transcranial Doppler combined with quantitative EEG brain function monitoring and outcome prediction in patients with severe acute intracerebral hemorrhage. AB - BACKGROUND: Neurological deterioration after intracerebral hemorrhage (ICH) is thought to be closely related to increased intracranial pressure (ICP), decreased cerebral blood flow (CBF), and brain metabolism. Transcranial Doppler (TCD) is increasingly used as an indirect measure of ICP, and quantitative EEG (QEEG) can reflect the coupling of CBF and metabolism. We aimed to combine TCD and QEEG to comprehensively assess brain function after ICH and provide prognostic diagnosis. METHODS: We prospectively enrolled patients with severe acute supratentorial (SAS)-ICH from June 2015 to December 2016. Mortality was assessed at 90-day follow-up. We collected demographic data, serological data, and clinical factors, and performed neurophysiological tests at study entry. Quantitative brain function monitoring was performed using a TCD-QEEG recording system at the patient's bedside (NSD-8100; Delica, China). Univariate and multivariable analyses and receiver operating characteristic (ROC) curves were employed to assess the relationships between variables and outcome. RESULTS: Forty-seven patients (67.3 +/- 12.6 years; 23 men) were studied. Mortality at 90 days was 55.3%. Statistical results showed there were no significant differences in brain symmetry index between survivors and nonsurvivors, nor between patients and controls (all p > 0.05). Only TCD indicators of the pulsatility index from unaffected hemispheres (UPI) (OR 2.373, CI 1.299-4.335, p = 0.005) and QEEG indicators of the delta/alpha ratio (DAR) (OR 5.306, CI 1.533-18.360, p = 0.008) were independent predictors for clinical outcome. The area under the ROC curve after the combination of UPI and DAR was 0.949, which showed better predictive accuracy compared to individual variables. CONCLUSIONS: In patients with SAS-ICH, multimodal neuromonitoring with TCD combined with QEEG indicated that brain damage caused diffuse changes, and the predictive accuracy after combined use of TCD-QEEG was statistically superior in performance to any single variable, whether clinical or neurophysiological. PMID- 29463291 TI - Hypertonic saline infusion for treating intracranial hypertension after severe traumatic brain injury. AB - Traumatic brain injury (TBI) remains a major cause of mortality and disability. Post-traumatic intracranial hypertension (ICH) further complicates the care of patients. Hyperosmolar agents are recommended for the treatment of ICH, but no consensus or high-level data exist on the use of any particular agent or the route of administration. The two agents used commonly are hypertonic saline (HTS) and mannitol given as bolus therapy. Smaller studies suggest that HTS may be a superior agent in reducing the ICH burden, but neither agent has been shown to improve mortality or functional outcome. In a recently published analysis of pooled data from three prospective clinical trials, continuous infusion of HTS correlated with serum hypernatremia and reduced ICH burden in addition to improving 90-day mortality and functional outcome. This lays the foundation for the upcoming continuous hyperosmolar therapy for traumatic brain-injured patients (COBI) randomized controlled trial to study the outcome benefit of continuous HTS infusion to treat ICH after severe TBI. This is much anticipated and will be a high impact trial should the results be replicated. However, this would still leave a question over the use of mannitol bolus therapy which will need to be studied. PMID- 29463292 TI - Effectiveness of interventions aimed at improving physical and psychological outcomes of fall-related injuries in people with dementia: a narrative systematic review. AB - BACKGROUND: The annual prevalence of falls in people with dementia ranges from 47 to 90%. Falls are a common reason for hospital admission in people with dementia, and there is limited research evidence regarding the care pathways experienced by this population. In addition to immediate management of an injury, prevention of further falls is likely to be an important part of any successful intervention. This review aims to assess the effectiveness of interventions for improving the physical and psychological wellbeing of people with dementia who have sustained a fall-related injury. METHODS: Systematic review methodologies were employed utilising searches across multiple databases (MEDLINE, CENTRAL, Health Management Information Consortium, EMBASE, CINAHL, Web of Science, Allied and Complementary Medicine Database, and Physiotherapy Evidence Database (PEDro)) and citation chaining. Studies including people with a known diagnosis of dementia living in the community and who present at health services with a fall, with or without injury, were included. Outcomes of interest included mobility, recurrent falls, activities of daily living, length of hospital stay, and post-discharge residence. Results were independently reviewed and quality assessed by two researchers, and data extracted using a customised form. A narrative synthesis was performed due to heterogeneity of the included studies. RESULTS: Seven studies were included. Interventions clustered into three broad categories: multidisciplinary in-hospital post-surgical geriatric assessment; pharmaceuticals; and multifactorial assessment. Multidisciplinary care and early mobilisation showed short-term improvements for some outcomes. Only an annual administration of zoledronic acid showed long-term reduction in recurrent falls. CONCLUSIONS: Due to high heterogeneity across the studies, definitive conclusions could not be reached. Most post-fall interventions were not aimed at patients with dementia and have shown little efficacy regardless of cognitive status. Minor improvements to some quality of life indicators were shown, but these were generally not statistically significant. Conclusions were also limited due to most studies addressing hip fracture; the interventions provided for this type of injury may not be suitable for other types of fractures or soft tissue injuries, or for use in primary care.

AB - OBJECTIVE: Intestinal parasites and H. pylori are well-known for their high prevalence worldwide. Thus, the objective of this study waste assess risk factors and co-infection of intestinal parasites and H. pylori among adult patients with upper gastrointestinal complaints. A hospital-based cross sectional study was conducted among 363 consecutive adult patients from December 10, 2015 to February 30,2016. Stool and venous blood were collected for analysis of Intestinal parasites and H. pylori infection, respectively. Data was analyzed using SPSS version 16 and logistic regression analysis was carried out to assess predictors of co-infection. A p <= 0.05 was considered as statistically significant. RESULTS: Helicobacter pylori IgG and intestinal parasites were detected in 70.25 38.3% of participants, respectively while G. lamblia accounted 22.3%. G. lamblia prevalence was significantly higher among H. pylori infected participants (COR: 2.76; 95% CI: 1.46-5.23), but E. hystolytica/dispar infection didn't show significant variation (p = 0.15). H. pylori and intestinal parasites concomitant co-infection was associated with male sex (AOR: 1.61; 95% CI: 1.01-2.56), consumption of river water (AOR: 1.85; 95% CI: 1.11-3.07) and ground/spring water (AOR: 4.10; 95% CI: 1.97-8.52). Thus, besides H. pylori investigation, upper gastrointestinal symptomatic patients should be screened for G. lamblia infection and other intestinal parasites. PMID- 29463294 TI - Rare variant of metaplastic carcinoma of the breast: a case report and review of the literature. AB - BACKGROUND: Metaplastic carcinoma encompasses a group of neoplasms characterized by differentiation of the neoplastic epithelium into squamous cells and/or mesenchymal-looking elements. Spindle cell carcinoma is a rare variant of this special histological type. Its prognosis remains poor, with a high rate of local recurrence and distant metastasis. To date, only a small number of cases have been described. There is no clear agreement on this histological subtype. CASE PRESENTATION: We report a case of a 53-year-old Moroccan woman who consulted our institution following palpation of a nodule of the left breast. Mammography in combination with breast ultrasonography revealed a lesion classified as Breast Imaging Reporting and Data System 4 with microcalcification. The patient was diagnosed with spindle cell carcinoma of the breast. The diagnosis was based primarily on histological and immunohistochemical studies of the breast biopsy and secondarily on the surgical specimen. No local or distant metastasis was found. The treatment used was total surgical excision followed by radiotherapy. CONCLUSIONS: We describe the features (epidemiological, clinical, histological, immunohistochemical, and therapeutic outcomes) of our patient's case and compare them with literature data. PMID- 29463295 TI - Thermal regime and host clade, rather than geography, drive Symbiodinium and bacterial assemblages in the scleractinian coral Pocillopora damicornis sensu lato. AB - BACKGROUND: Although the term holobiont has been popularized in corals with the advent of the hologenome theory of evolution, the underlying concepts are still a matter of debate. Indeed, the relative contribution of host and environment and especially thermal regime in shaping the microbial communities should be examined carefully to evaluate the potential role of symbionts for holobiont adaptation in the context of global changes. We used the sessile, long-lived, symbiotic and environmentally sensitive reef-building coral Pocillopora damicornis to address these issues. RESULTS: We sampled Pocillopora damicornis colonies corresponding to two different mitochondrial lineages in different geographic areas displaying different thermal regimes: Djibouti, French Polynesia, New Caledonia, and Taiwan. The community composition of bacteria and the algal endosymbiont Symbiodinium were characterized using high-throughput sequencing of 16S rRNA gene and internal transcribed spacer, ITS2, respectively. Bacterial microbiota was very diverse with high prevalence of Endozoicomonas, Arcobacter, and Acinetobacter in all samples. While Symbiodinium sub-clade C1 was dominant in Taiwan and New Caledonia, D1 was dominant in Djibouti and French Polynesia. Moreover, we also identified a high background diversity (i.e., with proportions < 1%) of A1, C3, C15, and G Symbiodinum sub-clades. Using redundancy analyses, we found that the effect of geography was very low for both communities and that host genotypes and temperatures differently influenced Symbiodinium and bacterial microbiota. Indeed, while the constraint of host haplotype was higher than temperatures on bacterial composition, we showed for the first time a strong relationship between the composition of Symbiodinium communities and minimal sea surface temperatures. CONCLUSION: Because Symbiodinium assemblages are more constrained by the thermal regime than bacterial communities, we propose that their contribution to adaptive capacities of the holobiont to temperature changes might be higher than the influence of bacterial microbiota. Moreover, the link between Symbiodinium community composition and minimal temperatures suggests low relative fitness of clade D at lower temperatures. This observation is particularly relevant in the context of climate change, since corals will face increasing temperatures as well as much frequent abnormal cold episodes in some areas of the world. PMID- 29463297 TI - Implementation of a competency-based medical education approach in public health and epidemiology training of medical students. AB - BACKGROUND: There is increasing agreement among medical educators regarding the importance of improving the integration between public health and clinical education, understanding and implementation of epidemiological methods, and the ability to critically appraise medical literature. The Sackler School of Medicine at Tel-Aviv University revised its public health and preventive medicine curriculum, during 2013-2014, according to the competency-based medical education (CBME) approach in training medical students. We describe the revised curriculum, which aimed to strengthen competencies in quantitative research methods, epidemiology, public health and preventive medicine, and health service organization and delivery. METHODS: We report the process undertaken to establish a relevant 6-year longitudinal curriculum and describe its contents, implementation, and continuous assessment and evaluation. RESULTS: Central competencies included: epidemiology and statistics for appraisal of the literature and implementation of research; the application of health promotion principles and health education strategies in disease prevention; the use of an evidence-based approach in clinical and public health decision making; the examination and analysis of disease trends at the population level; and knowledge of the structure of health systems and the role of the physician in these systems. Two new courses, in health promotion, and in public health, were added to the curriculum, and the courses in statistics and epidemiology were joined. Annual evaluation of each course results in continuous revisions of the syllabi as needed, while we continue to monitor the whole curriculum. CONCLUSIONS: The described revision in a 6 year-medical school training curriculum addresses the currently identified needs in public health. Ongoing feedback from students, and re-evaluation of syllabus by courses teams are held annually. Analysis of student's written feedbacks and courses evaluations of "before and after" the implementation of this intervention is taking place to examine the effect of the new curriculum on the perceived clinical and research capacities of our 6-year students. PMID- 29463296 TI - Nilotinib impairs skeletal myogenesis by increasing myoblast proliferation. AB - BACKGROUND: Tyrosine kinase inhibitors (TKIs) are effective therapies with demonstrated antineoplastic activity. Nilotinib is a second-generation FDA approved TKI designed to overcome Imatinib resistance and intolerance in patients with chronic myelogenous leukemia (CML). Interestingly, TKIs have also been shown to be an efficient treatment for several non-malignant disorders such fibrotic diseases, including those affecting skeletal muscles. METHODS: We investigated the role of Nilotinib on skeletal myogenesis using the well-established C2C12 myoblast cell line. We evaluated the impact of Nilotinib during the time course of skeletal myogenesis. We compared the effect of Nilotinib with the well-known p38 MAPK inhibitor SB203580. MEK1/2 UO126 and PI3K/AKT LY294002 inhibitors were used to identify the signaling pathways involved in Nilotinib-related effects on myoblast. Adult primary myoblasts were also used to corroborate the inhibition of myoblasts fusion and myotube-nuclei positioning by Nilotinib. RESULTS: We found that Nilotinib inhibited myogenic differentiation, reducing the number of myogenin-positive myoblasts and decreasing myogenin and MyoD expression. Furthermore, Nilotinib-mediated anti-myogenic effects impair myotube formation, myosin heavy chain expression, and compromise myotube-nuclei positioning. In addition, we found that p38 MAPK is a new off-target protein of Nilotinib, which causes inhibition of p38 phosphorylation in a similar manner as the well characterized p38 inhibitor SB203580. Nilotinib induces the activation of ERK1/2 and AKT on myoblasts but not in myotubes. We also found that Nilotinib stimulates myoblast proliferation, a process dependent on ERK1/2 and AKT activation. CONCLUSIONS: Our findings suggest that Nilotinib may have important negative effects on muscle homeostasis, inhibiting myogenic differentiation but stimulating myoblasts proliferation. Additionally, we found that Nilotinib stimulates the activation of ERK1/2 and AKT. On the other hand, we suggest that p38 MAPK is a new off-target of Nilotinib. Thus, there is a necessity for future studies to investigate the long-term effects of TKIs on skeletal muscle homeostasis, along with potential detrimental effects in cell differentiation and proliferation in patients receiving TKI therapies. PMID- 29463298 TI - Registration of systematic reviews in PROSPERO: 30,000 records and counting. AB - BACKGROUND: The International Prospective Register of Systematic Reviews (PROSPERO) was launched in February 2011 to increase transparency of systematic reviews (SRs). There have been few investigations of the content and use of the database. We aimed to investigate the number of PROSPERO registrations from inception to 2017, and website usage in the last year. We also aimed to explore the epidemiological characteristics of and completeness of primary outcome pre specification in a sample of PROSPERO records from 2017. METHODS: The PROSPERO database managers provided us with data on the annual and cumulative number of SR registrations up to October 10, 2017, and the number of visits to the PROSPERO website over the year preceding October 10, 2017. One author collected data on the focus of the SR (e.g. therapeutic, diagnostic), health area addressed, funding source and completeness of outcome pre-specification in a random sample of 150 records of SRs registered in PROSPERO between April 1, 2017 and September 30, 2017. RESULTS: As of October 10, 2017, there were 26,535 SRs registered in PROSPERO; guided by current monthly submission rates, we anticipate this figure will reach over 30,000 by the end of 2017. There has been a 10-fold increase in registrations, from 63 SRs per month in 2012 to 800 per month in 2017. In the year preceding October 10, 2017, the PROSPERO website received more than 1.75 million page views. In the random sample of 150 registered SRs, the majority were focused on a therapeutic question (78/150 [52%]), while only a few focused on a diagnostic/prognostic question (11/150 [7%]). The 150 registered SRs addressed 18 different health areas. Any information about the primary outcome other than the domain (e.g. timing, effect measures) was not pre-specified in 44/150 records (29%). CONCLUSIONS: Registration of SRs in PROSPERO increased rapidly between 2011 and 2017, thus benefiting users of health evidence who want to know about ongoing SRs. Further work is needed to explore how closely published SRs adhere to the planned methods, whether greater pre-specification of outcomes prevents selective inclusion and reporting of study results, and whether registered SRs address necessary questions. PMID- 29463299 TI - Risk factors associated with precancerous cervical lesion among women screened at Marie Stops Ethiopia, Adama town, Ethiopia 2017: a case control study. AB - OBJECTIVE: Although cervical cancer is a preventable disease, it remains a leading cause of death among women in developing countries. In this unmatched case control design, 55 cases and 109 controls were included. The main objective of this study was to assess the risk factors of precancerous cervical lesion in Adama town. RESULTS: A total of 164 participants were recruited in this study. Of the 109 controls, 64 (61%) and 41 (39%) of cases were using oral contraception. Women who were using oral contraception were two times at risk for developing precancerous cervical lesion than who were not using (COR = 2.059 95% CI 1.006, 4.216; AOR = 2.342). Out of 55 cases, 21 (38.2%) cases had a history STI and out of 109 controls, 24 (22.2%) controls had a history of STI. It was revealed that STI has a significant association for developing of precancerous lesion. Women who had a history of STI were two times at risk of developing precancerous cervical lesion than who had no (COR = 2.187; AOR = 2.485). It was found that initiation of sexual intercourse before the age of 15 years has 5.6 risks to develop precancerous cervical lesion (COR = 5.625 AOR = 6.703). PMID- 29463300 TI - Effectiveness of a field trap barrier system for controlling Aedes albopictus: a "removal trapping" strategy. AB - BACKGROUND: Aedes aegypti and Aedes albopictus are the main vectors for the transmission of several viral pathogens, in particular, dengue, Zika and chikungunya. In the absence of vaccines and treatment, control of Aedes mosquitoes is the only means of keeping these diseases in check. Aedes control is difficult, and it is, therefore, necessary to evaluate the efficacy of novel control methods, particularly those targeting adult and exophilic Ae. albopictus populations. METHODS: We carried out the first evaluation of the effectiveness of a field trap barrier system, i.e. a "removal trapping" outdoor control strategy for Ae. albopictus in southern France. RESULTS: The removal trapping control strategy is an effective system, able to reduce to almost zero the biting rate of the tiger mosquito in and around houses with traps installed. This strategy has the advantage of being a non-chemical method, which is environmentally friendly and does not affect non-target fauna. Nevertheless, it has several constraints including the cost of the CO2 required for the system to function. However, the system could be optimized by reducing the costs and combining it with other control strategies within the framework of integrated vector management. CONCLUSIONS: We provide the first evidence of the effectiveness of this trap barrier system, which is based on the combined effect of (i) removing adult mosquitoes living in the area, and (ii) hampering the migration of mosquitoes from outside into the treated area. Further investigation is needed to understand its efficacy for other species, other locations and at-risk communities, and to evaluate its application for reducing the prevalence of dengue, Zika and chikungunya diseases. PMID- 29463301 TI - Molecular detection of colistin resistance genes (mcr-1 to mcr-5) in human vaginal swabs. AB - OBJECTIVE: Colistin resistance has emerged worldwide and has been threatening the efficacy of one of the last-resort antimicrobials used for treatment of multidrug resistant Gram-negative bacteria. While five colistin resistance genes (mcr-1, mcr-2, mcr-3, mcr-4 and mcr-5) have been described, few data are available on the prevalence of mcr-genes other than mcr-1 in human samples. RESULTS: In this study, the presence of five currently described colistin resistance genes (mcr 1 5) in vaginal swabs of women undergoing infertility evaluation was reported. Most samples were found to be positive for the mcr-4 (12.7%), followed by two for the mcr-2 (1.5%), two for the mcr-3 (1.5%), one for the mcr-1 (0.7%), and one for the mcr-5 (0.7%). Phylogenetic comparison demonstrated identical (mcr-1, mcr-2, mcr 3, mcr-5) or similar (mcr-4) nucleotide sequences of human samples and those of animal origins from the same city, suggesting the potential transmission of mcr genes from animals to humans. This is the first detection of mcr-2, mcr-4 and mcr 5 genes in human samples, and warrants further research to determine the spread of the mcr genes and elucidate the full epidemiology of colistin resistance genes in humans. PMID- 29463302 TI - The impact of PD-L1 on survival and value of the immune check point inhibitors in non-small-cell lung cancer; proposal, policies and perspective. AB - BACKGROUND: The impact of programmed death receptor-ligand1 (PD-L1) on costs and value of the immune check point inhibitors (ICPI) has received minimal attention. OBJECTIVES: 1- Design a sliding scale to grade survival in 2nd-line non-small cell lung cancer (NSCLC). 2- Compare costs and value of Nivolumab (Nivo), Atezolizumab (Atezo) and Pembrolizumab (Pembro) vs. Docetaxel (Doc). METHODS: Previously reported median overall survival (OS) and prices posted by parent company were utilized. The OS gains over controls in days were graded (gr) from A+ to D. Docetaxel costs were calculated for 6-12 cycles and the ICPI for 1 year. Adverse events treatment costs (AEsTC) were reported separately. The cost/life year gain (C/LYG) was computed as drug yearly-cost/OS gain over control in days * 360 days. The relative value of the ICPI were expressed as $100,000/C/LYG. RESULTS: Costs of Doc 6 cycles were $23,868, OS/gr 87/C, AEs gr 3/4 > 20%, AEsTC $1978 and 6- 12 cycle C/LYG $98,764 -$197,528. Nivo, Atezo and Pembro gr 3/4 were < 20% at average costs of $1480. In non-squamous NSCLC, Nivo demonstrated OS/g 84/C and C/LYG $558,326 as compared with 264/A and $177,645 in PD-L1 > 10%. Atezolizumab OS/g were 87/B and C/LYG $551,407 improving in enriched PD-L1 to 162/A and $332,020 respectively. Pembrolizumab in PD-L1 > 1.0% demonstrated OS/g 57/C and C/LYG $659,059 improving in > 50% PD-L1 to 201/A and $186,897. PD-L1 enrichment increased RV of Nivo from 0.18 to 0.56, Atezo from 0.16 to 0.66 and Pembro from 0.15 to 0.53. CONCLUSIONS: Simplified methodology to grade OS and weigh value of anticancer drugs was proposed. In 2nd-line non-squamous NSCLC, value of Doc, Nivo, Atezo and Pembro regardless of PDL-1 expression were limited and modest. Enrichment of PD-L1 resulted in unprecedented OS, improved grades and enhanced value at seemingly justifiable costs. PMID- 29463303 TI - Development and evaluation of 16 new microsatellite loci for the rock ptarmigan (Lagopus muta) and cross-species amplification for the willow grouse (L. lagopus). AB - OBJECTIVE: The genetic markers designed for this study can facilitate future genetic studies on the rock ptarmigan (Lagopus muta). To our knowledge no microsatellite markers have ever been developed specifically for this species before. These new microsatellite markers will be useful for population genetics studies and for future conservation projects. RESULTS: Using Next Generation Sequencing 6252 potential microsatellite sequences were found. Sixteen nonpalindromic tetranucleotide microsatellites and their respective primers were selected. The markers were tested on both the rock ptarmigan and the willow grouse (L. lagopus). The number of alleles varied between 2 and 18 for the rock ptarmigan, and between 3 and 13 for the willow grouse. Expected heterozygosity was in the range 0.1244-0.8692 and 0.1358-0.8722 for the rock ptarmigan and the willow grouse, respectively. PMID- 29463304 TI - Schistosoma mansoni and other intestinal parasitic infections in schoolchildren and vervet monkeys in Lake Ziway area, Ethiopia. AB - OBJECTIVE: To assess Schistosoma mansoni and other intestinal parasitic infections in schoolchildren and vervet monkeys (Chlorocebus aethiops) in Bochessa Village, Ziway, Ethiopia. RESULTS: Fecal specimens from selected schoolchildren and droppings of the vervet monkeys were collected and microscopically examined for intestinal parasites using the Kato-Katz thick smear and formol-ether concentration techniques. The prevalences of S. mansoni, Trichuris trichiura, Ascaris lumbricoides, Enterobius vermicularis, hookworms, Hymenolepis nana and Taenia species among the children were 35.7, 26.9, 24.1, 2.1, 2.1, 1.07 and 2.1%, respectively (by Kato-Katz) and 39.3, 36.1, 35.6, 2.9, 10.0, 4.3, and 2.9%, respectively (by formol-ether concentration). Prevalence of S. mansoni in vervet monkeys ranged from 10 to 20%. B. pfeifferi snails were exposed to S. mansoni miracidia from vervet origin, shed cercariae were then used to infect lab-bred albino mice. Adult worms were harvested from the mice 5 weeks post-exposure to cercariae to establish the schistosome life cycle and confirm the infection in the vervet monkeys. The natural infection of S. mansoni in vervet monkeys suggests that the non-human primate is likely to be implicated in the local transmission of schistosomiasis. Further epidemiological and molecular studies are needed to fully elucidate zoonotic role of non-human primate in the area. PMID- 29463305 TI - Lysozyme improves gut performance and protects against enterotoxigenic Escherichia coli infection in neonatal piglets. AB - Diarrhea remains one of the leading causes of morbidity and mortality globally, with enterotoxigenic Escherichia coli (ETEC) constituting a major causative pathogen. The development of alternative treatments for diarrhea that do not involve chemotherapeutic drugs or result in antibiotic resistance is critical. Considering that lysozyme is a naturally occurring antimicrobial peptide, in a previous study we developed a transgenic pig line that expresses recombinant human lysozyme (hLZ) in its milk. In the present study, we examined the protective effects of the consumption of this milk against ETEC infection in neonatal piglets. We found that consuming hLZ milk facilitated faster recovery from infection and decreased mortality and morbidity following an ETEC oral inoculation or infection acquired by contact-exposure. The protective effect of hLZ was associated with the enrichment of intestinal bacteria that improve gut health, such as Lactobacillus, and the enhancement of the mucosal IgA response to the ETEC-induced diarrhea. Our study revealed potential protective mechanisms underlying the antimicrobial activity of human lysozyme, validating the use of lysozyme as an effective preventive measure for diarrhea. PMID- 29463306 TI - Fanconi anemia core complex-dependent HES1 mono-ubiquitination regulates its transcriptional activity. AB - OBJECTIVE: The Hairy Enhancer of Split 1 (HES1) is a transcriptional repressor that regulates cellular proliferation and differentiation during development. We previously found an interaction between HES1 and Fanconi anemia (FA) proteins. FA is a hematological and developmental disorder caused by mutations in more than 20 different genes. Eight FA gene products form a nuclear core complex containing E3 ligase activity required for mono-ubiquitination of FANCD2 and FANCI, both of which are FA proteins. Given that HES1 interacts with members of the FA core complex, the aim of this study was to determine whether HES1 is mono ubiquitinated via the FA core complex. RESULTS: We show that HES1 is mono ubiquitinated on a highly-conserved lysine residue that is located within a FA like recognition motif. HES1 modification is dependent on a functional FA complex. Absence of HES1 mono-ubiquitination affects transcriptional repression of its own promoter. This study uncovers a novel post-translational modification of HES1 that regulates its transcriptional activity and suggests that ubiquitination of HES1 occurs in a FA core complex-dependent manner. PMID- 29463307 TI - How elimination of lymphatic filariasis as a public health problem in the Kingdom of Cambodia was achieved. AB - BACKGROUND: Endemicity of lymphatic filariasis (LF) in Cambodia was proven in 1956 when microfilariae were detected in mosquitos in the Kratie province. In 2001, an extensive study confirmed the presence of both Brugia malayi and Wuchereria bancrofti microfilariae. In 2003, the Ministry of Health established a national task force to develop policies and strategies for controlling and eliminating neglected tropical diseases (NTDs), with the goal of eliminating LF by 2015. This article summarizes the work accomplished to eliminate LF as a public health problem in Cambodia. METHODS: The National Program to Eliminate Lymphatic Filariasis made excellent progress in the goal towards elimination due to strong collaboration between ministries, intensive supervision by national staff, and advocacy for mobilization of internal and external resources. Mass drug administration (MDA) with diethylcarbamazine citrate and albendazole was conducted in six implementation units, achieving > 70% epidemiological coverage for five consecutive rounds, from 2005 to 2009. In 2006, in 14 provinces, healthcare workers developed a line list of lymphedema and hydrocele patients, many of whom were > 40 years old and had been affected by LF for many years. The national program also trained healthcare workers and provincial and district staff in morbidity management and disability prevention, and designated health centers to provide care for lymphedema and acute attack. Two reference hospitals were designated to administer hydrocele surgery. RESULTS: Effectiveness of MDA was proven with transmission assessment surveys. These found that less than 1% of school children had antigenemia in 2010, which fell to 0% in both 2013 and 2015. A separate survey in one province in 2015 using Brugia Rapid tests to test for LF antibody found one child positive among 1677 children. The list of chronic LF patients was most recently updated and confirmed in 2011-2012, with 32 lymphoedema patients and 17 hydrocele patients listed. All lymphedema patients had been trained on self-management and all hydrocele patients had been offered free surgery. CONCLUSIONS: Due to the success of the MDA and the development of health center capacity for patient care, along with benefits gained from socioeconomic improvements and other interventions against vector-borne diseases and NTDs, Cambodia was validated by the World Health Organization as achieving LF elimination as a public health problem in 2016. PMID- 29463309 TI - Zanthoxylum armatum DC extracts from fruit, bark and leaf induce hypolipidemic and hypoglycemic effects in mice- in vivo and in vitro study. AB - BACKGROUND: Zanthoxylum armatum DC is an important medicinal plant of south East Asia, and has been used to treat various ailments in traditional medicine including diabetes. This study investigated the in vitro and in vivo antidiabetic and biochemical effects of extracts of Z. armatum in mice. METHOD: The extracts of fruit, bark and leaf from Z. armatum were tested for alpha-glucosidase inhibition activity. Albino mice of either sex weighing (26-30 g) assigned into groups. Diabetes was induced by IP injection of alloxan monohydrate (150 mg/kg). The extracts (500 mg/kg) and standard (Glibenclamide 10 mg/kg) were administered to mice for 15 days. Serum biochemical parameters were monitored for the period of study. RESULTS: The leaves and bark extracts showed maximum alpha-glucosidase inhibition (96.61 +/- 2.13 and 93.58 +/- 2.31% respectively). The extracts treated and the standard treated groups showed significant decrease in the fasting blood glucose levels compared to diabetic control. The effect was more pronounced in mice treated with leaves extract. In the in vivo studies body weights of diabetic mice treated with Z. armatum extracts and the standard did not reduced to extent as observed in diabetic control and this difference was significant (p < 0.05). There was a significance (p < 0.001) improvement in blood hemoglobin, urea, creatinine, cholesterol, and triglycerides of the extracts treated diabetic mice. The extracts showed hypolipidemic effect by reducing the LDL level. The extracts produced no prominent changes in proteins levels. CONCLUSION: It can be concluded that Z. armatum extracts showed excellent antidiabetic potential in vivo and in vitro and could be considered for further appraisal in clinical assessment and drug development. PMID- 29463308 TI - Reproducibility of clinical research in critical care: a scoping review. AB - BACKGROUND: The ability to reproduce experiments is a defining principle of science. Reproducibility of clinical research has received relatively little scientific attention. However, it is important as it may inform clinical practice, research agendas, and the design of future studies. METHODS: We used scoping review methods to examine reproducibility within a cohort of randomized trials examining clinical critical care research and published in the top general medical and critical care journals. To identify relevant clinical practices, we searched the New England Journal of Medicine, The Lancet, and JAMA for randomized trials published up to April 2016. To identify a comprehensive set of studies for these practices, included articles informed secondary searches within other high impact medical and specialty journals. We included late-phase randomized controlled trials examining therapeutic clinical practices in adults admitted to general medical-surgical or specialty intensive care units (ICUs). Included articles were classified using a reproducibility framework. An original study was the first to evaluate a clinical practice. A reproduction attempt re-evaluated that practice in a new set of participants. RESULTS: Overall, 158 practices were examined in 275 included articles. A reproduction attempt was identified for 66 practices (42%, 95% CI 33-50%). Original studies reported larger effects than reproduction attempts (primary endpoint, risk difference 16.0%, 95% CI 11.6-20.5% vs. 8.4%, 95% CI 6.0-10.8%, P = 0.003). More than half of clinical practices with a reproduction attempt demonstrated effects that were inconsistent with the original study (56%, 95% CI 42-68%), among which a large number were reported to be efficacious in the original study and to lack efficacy in the reproduction attempt (34%, 95% CI 19-52%). Two practices reported to be efficacious in the original study were found to be harmful in the reproduction attempt. CONCLUSIONS: A minority of critical care practices with research published in high-profile journals were evaluated for reproducibility; less than half had reproducible effects. PMID- 29463310 TI - The practice of intensive care in Latin America: a survey of academic intensivists. AB - BACKGROUND: Intensive care medicine is a relatively young discipline that has rapidly grown into a full-fledged medical subspecialty. Intensivists are responsible for managing an ever-increasing number of patients with complex, life threatening diseases. Several factors may influence their performance, including age, training, experience, workload, and socioeconomic context. The aim of this study was to examine individual- and work-related aspects of the Latin American intensivist workforce, mainly with academic appointments, which might influence the quality of care provided. In consequence, we conducted a cross-sectional study of intensivists at public and private academic and nonacademic Latin American intensive care units (ICUs) through a web-based electronic survey submitted by email. Questions about personal aspects, work-related topics, and general clinical workflow were incorporated. RESULTS: Our study comprised 735 survey respondents (53% return rate) with the following country-specific breakdown: Brazil (29%); Argentina (19%); Chile (17%); Uruguay (12%); Ecuador (9%); Mexico (7%); Colombia (5%); and Bolivia, Peru, Guatemala, and Paraguay combined (2%). Latin American intensivists were predominantly male (68%) young adults (median age, 40 [IQR, 35-48] years) with a median clinical ICU experience of 10 (IQR, 5-20) years. The median weekly workload was 60 (IQR, 47-70) h. ICU formal training was between 2 and 4 years. Only 63% of academic ICUs performed multidisciplinary rounds. Most intensivists (85%) reported adequate conditions to manage patients with septic shock in their units. Unsatisfactory conditions were attributed to insufficient technology (11%), laboratory support (5%), imaging resources (5%), and drug shortages (5%). Seventy percent of intensivists participated in research, and 54% read scientific studies regularly, whereas 32% read no more than one scientific study per month. Research grants and pharmaceutical sponsorship are unusual funding sources in Latin America. Although Latin American intensivists are mostly unsatisfied with their income (81%), only a minority (27%) considered changing to another specialty before retirement. CONCLUSIONS: Latin American intensivists constitute a predominantly young adult workforce, mostly formally trained, have a high workload, and most are interested in research. They are under important limitations owing to resource constraints and overt dissatisfaction. Latin America may be representative of other world areas with similar challenges for intensivists. Specific initiatives aimed at addressing these situations need to be devised to improve the quality of critical care delivery in Latin America. PMID- 29463311 TI - Myeloid transformation of plasma cell myeloma: molecular evidence of clonal evolution revealed by next generation sequencing. AB - BACKGROUND: Plasma cell myeloma (PCM) is a neoplasm of terminally differentiated B lymphocytes with molecular heterogeneity. Although therapy-related myeloid neoplasms are common in plasma cell myeloma patients after chemotherapy, transdifferentiation of plasma cell myeloma into myeloid neoplasms has not been reported in literature. Here we report a very rare case of myeloid neoplasm transformed from plasma cell myeloma. CASE PRESENTATION: A 60-year-old man with a history of plasma cell myeloma with IGH-MAF gene rearrangement and RAS/RAF mutations developed multiple soft tissue lesions one year following melphalan based chemotherapy and autologous stem cell transplant. Morphological and immunohistochemical characterization of the extramedullary disease demonstrated that the tumor cells were derived from the monocyte-macrophage lineage. Next generation sequencing (NGS) studies detected similar clonal aberrations in the diagnostic plasma cell population and post-therapy neoplastic cells, including IGH-MAF rearrangement, multiple genetic mutations in RAS signaling pathway proteins, and loss of tumor suppressor genes. Molecular genetic analysis also revealed unique genomic alterations in the transformed tumor cells, including gain of NF1 and loss of TRAF3. CONCLUSION: To our knowledge, this is the first case of myeloid sarcoma transdifferentiated from plasma cell neoplasm. Our findings in this unique case suggest clonal evolution of plasma cell myeloma to myeloma neoplasm and the potential roles of abnormal RAS/RAF signaling pathway in lineage switch or transdifferentiation. PMID- 29463312 TI - SMS text messaging to measure working time: the design of a time use study among general practitioners. AB - BACKGROUND: Measuring the working hours of general practitioners (GPs) is an important but complex task due to the effects of bias related to self-reporting, recall, and stress. In this paper we describe the deployment, feasibility, and implementation of an innovative method for measuring, in real time, GPs' working time, plus the response to the study. METHODS: A Short Message Service (SMS) application was developed which sent messages at random to GPs during their working week. Approximately nineteen GPs participated each week during a period of 57 weeks. The text messages asked if GPs were doing activities related to patients, directly, indirectly, or not at all, at the moment of sending. Participants were requested to reply by SMS. RESULTS: Approximately 27,000 messages were sent to 1051 GPs over more than one year. The SMS system was functioning 99.9% of the time. GPs replied to 94% of all the messages sent. Only a few participants dropped out of the study. The data was available in real time enabling the researchers to monitor the response and overall quality of the data each day. CONCLUSIONS: The SMS method offers advantages over other instruments of measurement because it allows a better response, ease of use and avoids recall bias. This makes it a feasible method to collect valid data about GPs working time. PMID- 29463313 TI - Lymphotoxin beta receptor-mediated NFkappaB signaling promotes glial lineage differentiation and inhibits neuronal lineage differentiation in mouse brain neural stem/progenitor cells. AB - BACKGROUND: Lymphotoxin (LT) is a lymphokine mainly expressed in lymphocytes. LTalpha binds one or two membrane-associated LTbeta to form LTalpha2beta1 or LTalpha1beta2 heterotrimers. The predominant LTalpha1beta2 binds to LTbeta receptor (LTbetaR) primarily expressed in epithelial and stromal cells. Most studies on LTbetaR signaling have focused on the organization, development, and maintenance of lymphoid tissues. However, the roles of LTbetaR signaling in the nervous system, particularly in neurogenesis, remain unknown. Here, we investigated the role of LTbetaR-mediated NFkappaB signaling in regulating neural lineage differentiation. METHODS: The C57BL/6J wild-type and GFAP-dnIkappaBalpha transgenic mice were used. Serum-free embryoid bodies were cultured from mouse embryonic stem cells and further induced into neural stem/progenitor cells (NSCs/NPCs). Primary neurospheres were cultured from embryonic and adult mouse brains followed by monolayer culture for amplification/passage. NFkappaB activation was determined by adenovirus-mediated NFkappaB-firefly-luciferase reporter assay and p65/RelB/p52 nuclear translocation assay. LTbetaR mRNA expression was evaluated by quantitative RT-PCR and LTbetaR protein expression was determined by immunohistochemistry and Western blot analysis. Multilabeled immunocytochemistry or immunohistochemistry followed by fluorescent confocal microscopy and quantitative analysis of neural lineage differentiation were performed. Graphing and statistical analysis were performed with GraphPad Prism software. RESULTS: In cultured NSCs/NPCs, LTalpha1beta2 stimulation induced an activation of classical and non-classical NFkappaB signaling. The expression of LTbetaR-like immunoreactivity in GFAP+/Sox2+ NSCs was identified in well established neurogenic zones of adult mouse brain. Quantitative RT-PCR and Western blot analysis validated the expression of LTbetaR in cultured NSCs/NPCs and brain neurogenic regions. LTbetaR expression was significantly increased during neural induction. LTalpha1beta2 stimulation in cultured NSCs/NPCs promoted astroglial and oligodendrocytic lineage differentiation, but inhibited neuronal lineage differentiation. Astroglial NFkappaB inactivation in GFAP-dnIkappaBalpha transgenic mice rescued LTbetaR-mediated abnormal phenotypes of cultured NSCs/NPCs. CONCLUSION: This study provides the first evidence for the expression and function of LTbetaR signaling in NSCs/NPCs. Activation of LTbetaR signaling promotes glial lineage differentiation. Our results suggest that neurogenesis is regulated by the adaptive immunity and inflammatory responses. PMID- 29463314 TI - Functional brain-specific microvessels from iPSC-derived human brain microvascular endothelial cells: the role of matrix composition on monolayer formation. AB - BACKGROUND: Transwell-based models of the blood-brain barrier (BBB) incorporating monolayers of human brain microvascular endothelial cells (dhBMECs) derived from induced pluripotent stem cells show many of the key features of the BBB, including expression of transporters and efflux pumps, expression of tight junction proteins, and physiological values of transendothelial electrical resistance. The fabrication of 3D BBB models using dhBMECs has so far been unsuccessful due to the poor adhesion and survival of these cells on matrix materials commonly used in tissue engineering. METHODS: To address this issue, we systematically screened a wide range of matrix materials (collagen I, hyaluronic acid, and fibrin), compositions (laminin/entactin), protein coatings (fibronectin, laminin, collagen IV, perlecan, and agrin), and soluble factors (ROCK inhibitor and cyclic adenosine monophosphate) in 2D culture to assess cell adhesion, spreading, and barrier function. RESULTS: Cell coverage increased with stiffness of collagen I gels coated with collagen IV and fibronectin. On 7 mg mL 1 collagen I gels coated with basement membrane proteins (fibronectin, collagen IV, and laminin), cell coverage was high but did not reliably reach confluence. The transendothelial electrical resistance (TEER) on collagen I gels coated with basement membrane proteins was lower than on coated transwell membranes. Agrin, a heparin sulfate proteoglycan found in basement membranes of the brain, promoted monolayer formation but resulted in a significant decrease in transendothelial electrical resistance (TEER). However, the addition of ROCK inhibitor, cAMP, or cross-linking the gels to increase stiffness, resulted in a significant improvement of TEER values and enabled the formation of confluent monolayers. CONCLUSIONS: Having identified matrix compositions that promote monolayer formation and barrier function, we successfully fabricated dhBMEC microvessels in cross-linked collagen I gels coated with fibronectin and collagen IV, and treated with ROCK inhibitor and cAMP. We measured apparent permeability values for Lucifer yellow, comparable to values obtained in the transwell assay. During these experiments we observed no focal leaks, suggesting the formation of tight junctions that effectively block paracellular transport. PMID- 29463315 TI - X chromosome dosage and presence of SRY shape sex-specific differences in DNA methylation at an autosomal region in human cells. AB - BACKGROUND: Sexual dimorphism in DNA methylation levels is a recurrent epigenetic feature in different human cell types and has been implicated in predisposition to disease, such as psychiatric and autoimmune disorders. To elucidate the genetic origins of sex-specific DNA methylation, we examined DNA methylation levels in fibroblast cell lines and blood cells from individuals with different combinations of sex chromosome complements and sex phenotypes focusing on a single autosomal region--the differentially methylated region (DMR) in the promoter of the zona pellucida binding protein 2 (ZPBP2) as a reporter. RESULTS: Our data show that the presence of the sex determining region Y (SRY) was associated with lower methylation levels, whereas higher X chromosome dosage in the absence of SRY led to an increase in DNA methylation levels at the ZPBP2 DMR. We mapped the X-linked modifier of DNA methylation to the long arm of chromosome X (Xq13-q21) and tested the impact of mutations in the ATRX and RLIM genes, located in this region, on methylation levels. Neither ATRX nor RLIM mutations influenced ZPBP2 methylation in female carriers. CONCLUSIONS: We conclude that sex-specific methylation differences at the autosomal locus result from interaction between a Y-linked factor SRY and at least one X-linked factor that acts in a dose-dependent manner. PMID- 29463316 TI - Increased attachment security is related to early therapy drop-out in substance use disorders. AB - OBJECTIVES: Previous research work suggests a positive association between secure attachment and increased therapy adherence (TA) in different patient groups. However, there is still a strong need for research focusing on the influence of attachment on TA in substance use disorder (SUD) treatment. Hence, this study attempts to investigate the predictive value of different attachment patterns concerning TA in SUD inpatients. RESULTS: 122 (34 female) SUD inpatients completed the Attachment Style Questionnaire (ASQ) during the entry phase of therapeutic community treatment. After 6 weeks, subjects who remained in therapy (n = 47) completed the ASQ for a second time. In line with the literature, agglomerative Cluster Analysis suggested a two-cluster solution (Cluster I: increased secure attachment pattern; Cluster II: increased insecure attachment pattern). Notably, inpatients in Cluster I were more likely to drop out of treatment within the first 6 weeks (p < .001). Furthermore, subjects showed less "Confidence in Self and Others" (p < .05) after 6 weeks of treatment. Our findings indicate a negative predictive value of increased attachment security for TA in SUD inpatients. This finding probably mirrors a more realistic kind of self-assessment. More generally, the importance of considering attachment styles in SUD treatment is underlined. PMID- 29463317 TI - Adherence to the face-down positioning after vitrectomy and gas tamponade: a time series analysis. AB - OBJECTIVE: To determine the adherence to the face-down positioning (FDP) in 296 patients who had undergone vitrectomy and gas tamponade. RESULTS: We studied 119 female and 177 male patients who had undergone primary vitrectomy and gas tamponade for a macular hole (MH) or for rhegmatogenous retinal detachments (RRDs). Adherence was assessed and recorded four times per day for 3 days postsurgery. The mean +/- standard deviation adherence rate was 88.3 +/- 11.7 (range 50.0-100.0). Female patients (90.8 +/- 10.0) had significantly better adherence than male patients (86.7 +/- 13.3; P < 0.02, U test). The adherence was significantly better after MH surgery (90.8 +/- 11.7) than after RRD surgery (87.5 +/- 12.5; P < 0.02). There were diurnal variations in adherence, being highest in the evening and significantly lower at midnight, and we evidenced a decline in adherence over time, with it being significantly low on the last follow-up day. Adherence to the FDP varied considerably among patients. Adherence was higher in female than in male patients, and higher in patients with MH than in those with RRD. We found patients age had no effect on adherence. Adherence also varied with time, being worst at midnight and declining over time. PMID- 29463319 TI - Performance of Arma chinensis reared on an artificial diet formulated using transcriptomic methods. AB - An artificial diet formulated for continuous rearing of the predator Arma chinensis was inferior to natural prey when evaluated using life history parameters. A transcriptome analysis identified differentially expressed genes in diet-fed and prey-fed A. chinensis that were suggestive of molecular mechanisms underlying the nutritive impact of the artificial diet. Changes in the diet formulation were made based on the transcriptome analysis and tested using life history parameters. The quantity of pig liver, chicken egg, tuna fish, biotin, nicotinamide, vitamin B6, thiamine, riboflavin, vitamin C, L-glutamine, and sucrose was reduced, and wheat germ oil, calcium pantothenate and folic acid were increased. Ecuadorian shrimp was added as a partial substitute for tuna fish. Several parameters improved over six generations, including increased egg viability, and decreased egg and adult cannibalism. Additionally, several parameters declined, including longer developmental times for 2nd-5th instars, and decreased nymphal weights. The improvements in life history parameters support the use of transcriptome analyses to help direct formulation improvements. However, the decline in some parameters suggests that additional information, e.g., proteomic data, may be useful as well to maximize diet formulations. PMID- 29463318 TI - New and emerging uses of CRISPR/Cas9 to genetically manipulate apicomplexan parasites. AB - Although the application of CRISPR/Cas9 genome engineering approaches was first reported in apicomplexan parasites only 3 years ago, this technology has rapidly become an essential component of research on apicomplexan parasites. This review briefly describes the history of CRISPR/Cas9 and the principles behind its use along with documenting its implementation in apicomplexan parasites, especially Plasmodium spp. and Toxoplasma gondii. We also discuss the recent use of CRISPR/Cas9 for whole genome screening of gene knockout mutants in T. gondii and highlight its use for seminal genetic manipulations of Cryptosporidium spp. Finally, we consider new variations of CRISPR/Cas9 that have yet to be implemented in apicomplexans. Whereas CRISPR/Cas9 has already accelerated rapid interrogation of gene function in apicomplexans, the full potential of this technology is yet to be realized as new variations and innovations are integrated into the field. PMID- 29463320 TI - Medialisation thyroplasty with tensor fascia lata: a novel approach for reducing post-thyroplasty complications. AB - BACKGROUND: Medialisation thyroplasty is considered the 'gold standard' treatment for unilateral vocal fold paralysis, enabling improvement of voice and swallowing function, and preventing life-threatening aspiration events. The most commonly used laryngeal implants induce some degree of local tissue inflammatory response, and carry the risk of immediate or delayed implant extrusion. METHODS: This paper describes a novel approach for medialisation thyroplasty. Specifically, it utilises a ribbon of autologous tensor fascia lata harvested at the time of surgery. This is layered within the paraglottic space in a manner similar to Gore Tex thyroplasty. RESULTS: Thus far, this method has been accomplished in two patients with unilateral vocal fold paralysis, who also received prior radiotherapy to the head and neck. CONCLUSION: Given the increased risk of post operative wound breakdown and infection in irradiated patients, it is suggested that this new approach will lead to improved outcomes, and a decrease in complications such as extrusion or wound infection, particularly in this patient population. PMID- 29463321 TI - Olive cultivar and maturation process on the oviposition preference of Bactrocera oleae (Rossi) (Diptera: Tephritidae). AB - The olive fly, Bactrocera oleae (Rossi) (Diptera: Tephritidae), is a key-pest in the main olives producing areas worldwide, and displays distinct preference to different olive cultivars. The present work intended to study oviposition preference towards three Portuguese cultivars (Cobrancosa, Madural, and Verdeal Transmontana) at different maturation indexes. Multiple oviposition bioassays (multiple-choice and no-choice) were conducted to assess cultivar preference. No choice bioassays were conducted to assess the influence of different maturation indexes (MI 2; MI 3, and MI 4) in single cultivars. The longevity of olive fly adults according to the cultivar in which its larvae developed was also evaluated through survival assays. Cultivar and maturation are crucial aspects in olive fly preference. Field and laboratory assays revealed a preference towards cv. Verdeal Transmontana olives and a lower susceptibility to cv. Cobrancosa olives. A higher preference was observed for olives at MI 2 and MI 3. The slower maturation process in cv. Verdeal Transmontana (still green while the other cultivars are reddish or at black stage) seems to have an attractive effect on olive fly females, thus increasing its infestation levels. Olive fly adults from both sexes live longer if emerged from pupae developed from cv. Verdeal Transmontana fruits and live less if emerged from cv. Cobrancosa. Therefore, olive cultivar and maturation process are crucial aspects in olive fly preference, also influencing the longevity of adults. PMID- 29463322 TI - Factors influencing microhabitat selection and food preference of tree-dwelling earwigs (Dermaptera) in a temperate floodplain forest. AB - The ecology of earwigs in natural forest ecosystems is poorly understood. We used sweeping to determine the population densities of adult earwigs, by sex and species, on ten tree species in a temperate floodplain forest in southern Moravia (Czech Republic). We also determined the relationships between the properties of tree species and earwig density and diet as indicated by digestive tract contents. The densities and diet composition of earwigs differed between the three detected earwig species [Apterygida media (Hagenbach, 1822), Chelidurella acanthopygia (Gene, 1832) and Forficula auricularia Linnaeus, 1758] and among tree species. Earwig densities were related to lichen coverage and fungal coverage on the trees. The diet of earwigs was associated with specific leaf area, herbivore damage to the leaves, and light exposure of the trees. A. media was the most abundant of the three earwig species. Although the contents of its digestive tract changed depending on available food resources, A. media appeared to preferentially consume soft-bodied insect herbivores and fungi associated with wounds caused by herbivores rather than plant material. Therefore, this species has the potential to help reduce the population densities of soft-bodied pests of forest trees. PMID- 29463323 TI - Innate immunity and environmental correlates of Haemoproteus prevalence and intensity in an opportunistic breeder. AB - While parasite infection can have substantial fitness consequences in organisms, the predictors of parasite prevalence and intensity are often complex and vary depending on the host species. Here, we examined correlates of Haemoproteus (a common malaria parasite) prevalence and intensity in an opportunistically breeding songbird, the red crossbill (Loxia curvirostra). Specifically, we quantified Haemoproteus prevalence and intensity in crossbills caught in the Grand Teton National Park from 2010 to 2013. We found that parasite prevalence varies seasonally and across years, with the highest number of infected individuals occurring in the summer, although there was variation across summers sampled, and that prevalence was positively related to annual mean cone crop sizes (a measure of crossbill food abundance) and daily ambient temperature (a correlate of vector abundance). Parasite intensity was significantly and positively related to one measure of innate immunity, leucocyte counts per blood volume. Finally, neither crossbill age, ecomorph, nor sex had significant effects on parasite infection intensity; however, parasite prevalence did significantly vary among ecomorph and age classes. These results support the interpretation that a combination of physiological (specifically immune activity) and environmental factors affects parasite prevalence and infection intensity in this opportunistically breeding avian species. PMID- 29463324 TI - Functions of Turkish evidentials in early child-caregiver interactions: a growth curve analysis of longitudinal data. AB - In languages with evidential marking, utterances consist of an informational content and a specification of the mode of access to that information. In this first longitudinal study investigating the acquisition of the Turkish evidential marker -mIs in naturalistic child-caregiver interactions, we examined six children between 8 and 36 months of age. We charted individual differences in child and caregiver speech over time by conducting growth curve analyses. Children followed a similar course of acquisition in terms of the proportion of the marker in overall speech. However, children exhibited differences with respect to the order of emergence of different evidential functions (e.g., inference, hearsay), where each child showed a unique pattern irrespective of the frequency in caregiver input. Nonfactual use of the marker was very frequent in child and caregiver speech, where high-SES caregivers mostly produced the marker during story-telling and pretend play, and low-SES caregivers for regulating the child's behavior. PMID- 29463325 TI - Paediatric obstructive sleep apnoea: is our operative management evidence-based? AB - BACKGROUND: Despite the plethora of publications on the subject of paediatric obstructive sleep apnoea, there seems to be wide variability in the literature and in practice, regarding recourse to surgery, the operation chosen, the benefits gained and post-operative management. This may reflect a lack of high level evidence. METHODS: A systematic review of four significant controversies in paediatric ENT was conducted from the available literature: tonsillectomy versus tonsillotomy, focusing on the evidence base for each; anaesthetic considerations in paediatric obstructive sleep apnoea surgery; the objective evidence for the benefits of surgical treatment for obstructive sleep apnoea; and the medical treatment options for residual obstructive sleep apnoea after surgical treatment. RESULTS AND CONCLUSION: There are many gaps in the evidence base for the surgical correction of obstructive sleep apnoea. There is emerging evidence favouring subtotal tonsillectomy. There is continuing uncertainty around the prediction of the level of post-operative care that any individual child might require. The long-term benefit of surgical correction is a particularly fertile ground for further research. PMID- 29463326 TI - Functional characteristics of chemosensory proteins in the sawyer beetle Monochamus alternatus Hope. AB - The Japanese pine sawyer, Monochamus alternatus Hope (Coleoptera: Cerambycidae), is a major pest of pines and it is also the key vector of the exotic pinewood nematode in China. In the present study, we cloned, expressed, and purified a chemosensory protein (CSP) in M. alternatus. We surveyed its expression in various developmental stages of male and female adult tissues and determined its binding affinities for different pine volatiles using a competitive binding fluorescence assay. A CSP known as CSP5 in M. alternatus was obtained from an antennal cDNA library and expressed in Escherichia coli. Quantitative reverse transcription polymerase chain reaction results indicated that the CSP5 gene was mainly expressed in male and female antennae. Competitive binding assays were performed to test the binding affinity of recombinant CSP5 to 13 odour molecules of pine volatiles. The results showed that CSP5 showed very strong binding abilities to myrcene, (+)-beta-pinene, and (-)-isolongifolene, whereas the volatiles 2-methoxy-4-vinylphenol, p-cymene, and (+)-limonene oxide have relatively weak binding affinity at pH 5.0. Three volatiles myrcene, (+)-beta pinene, and (-)-isolongifolene may play crucial roles in CSP5 binding with ligands but this needs further study for confirmation. The sensitivity of insect to host plant volatiles can effectively be used to control and monitor the population through mass trapping as part of integrated pest management programs. PMID- 29463327 TI - Past trauma and future choices: differences in discounting in low-income, urban African Americans. AB - BACKGROUND: Exposure to traumatic events is surprisingly common, yet little is known about its effect on decision making beyond the fact that those with post traumatic stress disorder are more likely to have substance-abuse problems. We examined the effects of exposure to severe trauma on decision making in low income, urban African Americans, a group especially likely to have had such traumatic experiences. METHOD: Participants completed three decision-making tasks that assessed the subjective value of delayed monetary rewards and payments and of probabilistic rewards. Trauma-exposed cases and controls were propensity matched on demographic measures, treatment for psychological problems, and substance dependence. RESULTS: Trauma-exposed cases discounted the value of delayed rewards and delayed payments, but not probabilistic rewards, more steeply than controls. Surprisingly, given previous findings that suggested women are more affected by trauma when female and male participants' data were analyzed separately, only the male cases showed steeper delay discounting. Compared with nonalcoholic males who were not exposed to trauma, both severe trauma and alcohol dependence produced significantly steeper discounting of delayed rewards. CONCLUSIONS: The current study shows that exposure to severe trauma selectively affects fundamental decision-making processes. Only males were affected, and effects were observed only on discounting delayed outcomes (i.e. intertemporal choice) and not on discounting probabilistic outcomes (i.e. risky choice). These findings are the first to show significant differences in the effects of trauma on men's and women's decision making, and the selectivity of these effects has potentially important implications for treatment and also provides clues as to underlying mechanisms. PMID- 29463328 TI - Bilateral sudden sensorineural hearing loss as a first symptom of infective endocarditis: two case reports. AB - BACKGROUND: Septic emboli are an unusual cause of sudden sensorineural hearing loss, for which few reports exist in the literature. CASE REPORT: This paper presents two cases of sudden sensorineural hearing loss, initially considered as idiopathic, but which were caused by septic emboli. Hearing loss in these cases was bilateral, sequential and total. The first patient had mild fever one week prior to their presentation with sudden sensorineural hearing loss; the other patient had no additional symptoms at presentation. These patients were later diagnosed with infective endocarditis, at two and seven months following the sudden sensorineural hearing loss respectively, showing that septic emboli had been the cause of sudden sensorineural hearing loss. CONCLUSION: Septic emboli should be considered as a possible cause of sudden sensorineural hearing loss in cases of total hearing loss. This form of hearing loss should prompt the otolaryngologist to further investigate for infective endocarditis. PMID- 29463329 TI - Indirect visualisation of the upper pole during tonsillectomy. AB - BACKGROUND: During tonsillectomy, one of the key concerns is establishing adequate haemostasis. Intra-operative haemorrhage from the upper pole of the tonsil fossae can be a challenge to deal with because of an inability to clearly visualise bleeding points. Laryngeal mirrors are readily available in an ENT operating theatre and routinely used for indirect visualisation of the post-nasal space during adenoidectomy. OBJECTIVE: This paper describes a technique, utilising a laryngeal mirror placed within the tonsil fossa (after having removed the palatine tonsil), to visualise the upper pole and any bleeding points. RESULTS AND CONCLUSION: Laryngeal mirrors can be used with case to inspect the tonsil fossa post-tonsillectomy for bleeding points which may not be directly visible, so that these can be cauterised. PMID- 29463330 TI - A Chemical-Biological-Radio-Nuclear (CBRN) Filter can be Added to the Air-Outflow Port of a Ventilator to Protect a Home Ventilated Patient From Inhalation of Toxic Industrial Compounds. AB - OBJECTIVES: Chemical-biological-radio-nuclear (CBRN) gas masks are the standard means for protecting the general population from inhalation of toxic industrial compounds (TICs), for example after industrial accidents or terrorist attacks. However, such gas masks would not protect patients on home mechanical ventilation, as ventilator airflow would bypass the CBRN filter. We therefore evaluated in vivo the safety of adding a standard-issue CBRN filter to the air outflow port of a home ventilator, as a method for providing TIC protection to such patients. METHODS: Eight adult patients were included in the study. All had been on stable, chronic ventilation via a tracheostomy for at least 3 months before the study. Each patient was ventilated for a period of 1 hour with a standard-issue CBRN filter canister attached to the air-outflow port of their ventilator. Physiological and airflow measurements were made before, during, and after using the filter, and the patients reported their subjective sensation of ventilation continuously during the trial. RESULTS: For all patients, and throughout the entire study, no deterioration in any of the measured physiological parameters and no changes in measured airflow parameters were detected. All patients felt no subjective difference in the sensation of ventilation with the CBRN filter canister in situ, as compared with ventilation without it. This was true even for those patients who were breathing spontaneously and thus activating the ventilator's trigger/sensitivity function. No technical malfunctions of the ventilators occurred after addition of the CBRN filter canister to the air-outflow ports of the ventilators. CONCLUSIONS: A CBRN filter canister can be added to the air-outflow port of chronically ventilated patients, without causing an objective or subjective deterioration in the quality of the patients' mechanical ventilation.

PMID- 29463332 TI - Consumption of sugar-sweetened and artificially sweetened soft drinks and risk of obesity-related cancers. AB - OBJECTIVE: To test the hypothesis that more frequent consumption of sugar sweetened soft drinks would be associated with increased risk of obesity-related cancers. Associations for artificially sweetened soft drinks were assessed for comparison. DESIGN: Prospective cohort study with cancers identified by linkage to cancer registries. At baseline, participants completed a 121-item FFQ including separate questions about the number of times in the past year they had consumed sugar-sweetened or artificially sweetened soft drinks. Anthropometric measurements, including waist circumference, were taken and questions about smoking, leisure-time physical activity and intake of alcoholic beverages were completed. SETTING: The Melbourne Collaborative Cohort Study (MCCS) is a prospective cohort study which recruited 41 514 men and women aged 40-69 years between 1990 and 1994. A second wave of data collection occurred in 2003-2007. SUBJECTS: Data for 35 593 participants who developed 3283 incident obesity related cancers were included in the main analysis. RESULTS: Increasing frequency of consumption of both sugar-sweetened and artificially sweetened soft drinks was associated with greater waist circumference at baseline. For sugar-sweetened soft drinks, the hazard ratio (HR) for obesity-related cancers increased as frequency of consumption increased (HR for consumption >1/d v. 1/d v. <1/month=1.00; 95 % CI 0.79, 1.27; P-trend=0.61). CONCLUSIONS: Our results add to the justification to minimise intake of sugar-sweetened soft drinks. PMID- 29463333 TI - Why policy needs history (and historians). AB - Policy makers like the idea of new initiatives and fresh starts, unencumbered by, even actively overthrowing, what has been done in the past. At the same time, history can be pigeonholed as fusty and antiquarian, dealing with long past events of no relevance to the present. Academic historians are sometimes bound up in their own worlds. The debates central to academe may have little direct relevance to the immediate concerns of policy making. The paper argues that history, as the evidence-based discipline par excellence, is as relevant as other approaches to evidence-based policy making. Case studies can show us the nature of that relevance. How to achieve influence for history also needs discussion. The relationship is not straightforward and will vary according to time and place. History is an interpretative discipline, not just a collection of 'facts'. The paper discusses how historians work and why it is important for policy makers to engage, not just with history, but with historians as well. Historians too need to think about the value of bringing their analysis into policy. PMID- 29463334 TI - The Role of Oral Health in Complex Emergencies and Disaster Rehabilitation Medicine. AB - This paper presents an overview of the importance of oral health in complex emergencies. It highlights the importance of maintaining general and oral health in the acute, intermediate and long-term phases of such events which are increasing in frequency. The importance of oral health as an early warning sign for systemic disease and deprivation is also explored along with the crucial role of oral health in maintaining quality of life through adequate nutrition and speech. The overview of oral health in these situations identifies the need for training dental personnel as members of rehabilitation teams that set out to manage these disasters. They can quickly help in improving quality of life for victims by extracting carious and painful teeth as necessary, and also form part of an oral health education program for aid agencies. They can also be the first to identify systemic diseases like HIV and may also play a role in identifying victims of abuse, as non-accidental injuries can frequently present in the oro facial region. The oral health overview concludes by describing the contents of innovative oral health packs that are tailored to prevention of dental diseases and that can be readily incorporated as part of food packs distributed by aid agencies.

AB - Acute respiratory infections cause significant morbidity and mortality accounting for 5.8 million deaths worldwide. In Australia, influenza-like illness (ILI), defined as cough, fever and fatigue is a common presentation in general practice and results in reduced productivity and lost working days. Little is known about the epidemiology of ILI in working-age adults. Using data from the ASPREN influenza surveillance network in Australia (2010-2013) we found that working-age adults made up 45.2% of all ILI notifications with 55% of samples positive for at least one respiratory virus. Viruses most commonly detected in our study included influenza A (20.6%), rhinovirus (18.6%), influenza B (6.2%), human meta pneumovirus (3.4%), respiratory syncytial virus (3.1%), para-influenza virus (2.6%) and adenovirus (1.3%). We also demonstrated that influenza A is the predominant virus that increases ILI (by 1.2% per month for every positive influenza A case) in working-age adults during autumn-winter months while other viruses are active throughout the year. Understanding the epidemiology of viral respiratory infections through a year will help clinicians make informed decisions about testing, antibiotic and antiviral prescribing and when the beginning of the 'flu season' can be more confidently predicted. PMID- 29463337 TI - When regularization gets it wrong: children over-simplify language input only in production. AB - Children tend to regularize their productions when exposed to artificial languages, an advantageous response to unpredictable variation. But generalizations in natural languages are typically conditioned by factors that children ultimately learn. In two experiments, adult and six-year-old learners witnessed two novel classifiers, probabilistically conditioned by semantics. Whereas adults displayed high accuracy in their productions - applying the semantic criteria to familiar and novel items - children were oblivious to the semantic conditioning. Instead, children regularized their productions, over relying on only one classifier. However, in a two-alternative forced-choice task, children's performance revealed greater respect for the system's complexity: they selected both classifiers equally, without bias toward one or the other, and displayed better accuracy on familiar items. Given that natural languages are conditioned by multiple factors that children successfully learn, we suggest that their tendency to simplify in production stems from retrieval difficulty when a complex system has not yet been fully learned. PMID- 29463338 TI - A Novel Treatment Protocol (Nocebo Hypothesis Cognitive Behavioural Therapy; NH CBT) for Functional Neurological Symptom Disorder/Conversion Disorder: A Retrospective Consecutive Case Series. AB - BACKGROUND: Theories concerning the aetiology of functional neurological symptom disorder (FNSD; also known as conversion disorder) have historically inferred that psychological factors or dissociative states underlie patients' symptoms. Current psychological models of functional neurological symptoms suggest that some type of 'top-down' representations/beliefs are activated automatically (without conscious awareness), leading to symptoms. It is assumed that these representations or beliefs are similar to the idea 'I am neurologically damaged', as in our clinical experience, almost all patients have some reason to doubt the integrity of their neurological system. AIMS: It was hypothesized that FNSD arises from a belief of being neurologically damaged (via a mechanism akin to a nocebo response), and an interdisciplinary treatment protocol was developed consistent with this hypothesis, transparently sharing this theory with participants. METHOD: A retrospective consecutive case series design was utilized, measuring functional independence and symptom remission. RESULTS: Of the 13 episodes of care, 12 resulted in complete or almost complete symptom remission. Length of stay in rehabilitation was also reduced compared with previous treatment attempts. CONCLUSIONS: It appears as if the treatment protocol may be very effective, and further controlled study appears warranted.

To inform the development of disaster nursing curricula, a novel disaster nursing education method consistent with Homeland Security Exercise and Evaluation Program (HSEEP) and the International Council of Nurses (ICN) framework was developed to improve disaster nursing competencies in a baccalaureate nursing program. METHODS: In total, 89 undergraduate nursing students participated. Perceived disaster nursing knowledge, confidence, and training/response were assessed with 14 items before and after the education. RESULTS: Exploratory factor analysis showed 3 factors, knowledge, confidence, and training/response, explained 71% of variation in items. Nursing students showed large improvements in perceived disaster nursing knowledge (t=11.95, P<0.001, Cohen's d=1.76), moderate increases in perceived confidence (t=4.54, P<0.001, d=0.67), and no change in disaster training and response (t=0.94, P=0.351, d=0.13). CONCLUSIONS: Results show preliminary evidence supporting the effectiveness of disaster nursing education informed by HSEEP. This training has the potential to fill current practice gaps in disaster nursing knowledge and build confidence to use those skills in practice.

AB - BACKGROUND Clostridium difficile infection (CDI) presents a substantial economic burden and is associated with significant morbidity. While multiple treatment strategies have been evaluated, a cost-effective management strategy remains unclear. OBJECTIVE We conducted a systematic review to assess cost-effectiveness analyses of CDI treatment and to summarize key issues for clinicians and policy makers to consider. METHODS We searched PubMed and 5 other databases from inception to August 2016. These searches were not limited by study design or language of publication. Two reviewers independently screened the literature, abstracted data, and assessed methodological quality using the Drummond and Jefferson checklist. We extracted data on study characteristics, type of CDI, treatment characteristics, and model structure and inputs. RESULTS We included 14 studies, and 13 of these were from high-income countries. More than 90% of these studies were deemed moderate-to-high or high quality. Overall, 6 studies used a decision-tree model and 7 studies used a Markov model. Cost of therapy, time horizon, treatment cure rates, and recurrence rates were common influential factors in the study results. For initial CDI, fidaxomicin was a more cost effective therapy than metronidazole or vancomycin in 2 of 3 studies. For severe initial CDI, 2 of 3 studies found fidaxomicin to be the most cost-effective therapy. For recurrent CDI, fidaxomicin was cost-effective in 3 of 5 studies, while fecal microbiota transplantation (FMT) by colonoscopy was consistently cost effective in 4 of 4 studies. CONCLUSIONS The cost-effectiveness of fidaxomicin compared with other pharmacologic therapies was not definitive for either initial or recurrent CDI. Despite its high cost, FMT by colonoscopy may be a cost effective therapy for recurrent CDI. A consensus on model design and assumptions are necessary for future comparison of CDI treatment.

AB - The aim of this study was to evaluate the distribution of cases and the social determinants associated with death from human visceral leishmaniasis (HVL) and VL HIV co-infection in Belo Horizonte, Minas Gerais state, Brazil, between 2006 and 2013. Descriptive statistics and analysis of associations were performed using chi-square of the raised variables, such as sex, age, skin colour and schooling of cases of HVL. During the study period, there were 866 cases of HVL with 111 deaths in Belo Horizonte. Morbidity and lethality rates (LR) of HVL in Belo Horizonte remained high over almost all the years evaluated, with an average incidence rate of 4.18 cases/100 000 inhabitants and a LR of 11.16%. With respect to skin colour, it was found that people characterised as black or mulatto had higher morbidity, followed by white. Regarding schooling, LR was more prevalent among individuals with lower education. One of the social risk factors was co infection with HIV, which was present in many cases of HVL. Furthermore, it was found that older age and the male sex were also risk factors for death from HVL in Belo Horizonte.

AB - OBJECTIVE: To evaluate the efficacy and safety of segmental superficial parotidectomy in the surgical treatment of benign parotid tumours. METHODS: Patients who underwent parotidectomy for benign primary parotid tumours limited to the superficial lobe were retrospectively reviewed. Tumour location, size, surgical procedure, follow-up period, complications and recurrence rates were noted. RESULTS: The study included a total of 39 patients: 22 underwent segmental superficial parotidectomy (group 1) and 17 underwent superficial parotidectomy (group 2). The mean follow-up period was 41.79 months (range, 13-85 months). There were no recurrences in either group during the follow-up period. No significant differences were found between the two groups in terms of tumour size, complications or recurrence rates. CONCLUSION: Segmental superficial parotidectomy is a safe and effective option in the surgical treatment of benign parotid tumours. PMID- 29463343 TI - Characteristics associated with mortality in patients with chronic obstructive pulmonary disease (COPD)-heart failure coexistence. AB - : Aim To investigate if cardiac/pulmonary functional tests and variables obtained from clinical practice (body mass index, dyspnea, functional class, clinical judgment of disability to perform an exercise test and previous hospitalization rate) are related to mortality in patients with overlap chronic obstructive pulmonary disease (COPD) and chronic heart failure (CHF). BACKGROUND: Although the coexistence of COPD and CHF has been growingly reported, description of survival predictors considering the presence of both conditions is still scarce. METHODS: Using a cohort design, outpatients with the previous diagnosis of COPD and/or CHF that performed both spirometry and echocardiography in the same year were followed-up during a mean of 20.9+/-8.5 months. Findings Of the 550 patients initially evaluated, 301 had both spirometry and echocardiography: 160 (53%) with COPD on isolation; 100 (33%) with CHF on isolation; and 41 (14%) with overlap. All groups presented similar mortality: COPD 17/160 (11%); CHF 12/100 (12%); and overlap 7/41 (17%) (P=0.73). In the overlap group (n=41), inability to exercise and hospitalization rate were the unique parameters associated with higher mortality (seven events) in univariate analyses. In conclusion, inability to exercise and hospitalization rate emerged as the unique parameters associated with mortality in our sample.

AB - A 17-year-old girl with situs ambiguous, hypoplastic right ventricle with a large ventricular septal defect, and severe pulmonary stenosis had undergone Kawashima operation 10 years back. She had significant desaturation because of a large Abernethy malformation, with reverse shunting from the inferior caval vein to the portal vein. It was closed with a vascular plug, with improvement in oxygen saturation. She developed extensive inferior caval vein thrombus following the procedure, which was managed conservatively by anti-coagulation. PMID- 29463345 TI - 21st Century Cognitive Behavioural Therapy for Anger: A Systematic Review of Research Design, Methodology and Outcome. AB - BACKGROUND: Past reviews of cognitive behavioural therapy (CBT) for anger have focused on outcome in specific subpopulations, with few questions posed about research design and methodology. Since the turn of the century, there has been a surge of methodologically varied studies awaiting systematic review. AIMS: The basic aim was to review this recent literature in terms of trends and patterns in research design, operationalization of anger, and covariates such as social desirability bias (SDB). Also of interest was clinical outcome. METHOD: After successive culling, 42 relevant studies were retained. These were subjected to a rapid evidence assessment (REA) with special attention to design (ranked on the Scientific Methods Scale) measurement methodology (self-monitored behaviour, anger questionnaires, and others' ratings), SDB assessment, and statistical versus clinical significance. RESULTS: The randomized controlled trial characterized 60% of the studies, and the State Trait Anger Expression Inventory was the dominant measure of anger. All but one of the studies reported statistically significant outcome, and all but one of the 21 studies evaluating clinical significance laid claim to it. The one study with neither statistical nor clinical significance was the only one that had assessed and corrected for SDB. CONCLUSIONS: Measures remain relatively narrow in scope, but study designs have improved, and the outcomes suggest efficacy and clinical effectiveness. In conjunction with previous findings of an inverse relationship between anger and SDB, the results raise the possibility that the favourable picture of CBT for anger may need closer scrutiny with SDB and other methodological details in mind.

AB - We investigated influenza A(H5N6) viruses from migratory birds in Chungnam and Gyeonggi Provinces, South Korea following a reported die-off of poultry in nearby provinces in November 2017. Genetic analysis and virulence studies in chickens and ducks identified our isolate from December 2017 as a novel highly pathogenic avian influenza virus. It resulted from reassortment between the highly virulent H5N8 strain from Korea with the N6 gene from a low-pathogenic H3N6 virus from the Netherlands. PMID- 29463347 TI - Deciphering the Spectrum of Mitochondrial DNA Mutations in Hepatocellular Carcinoma Using High-Throughput Sequencing. AB - Accumulation of mitochondrial DNA (mtDNA) mutations has been proposed to contribute to the initiation and progression of tumors. By using high-throughput sequencing strategies, we measured 33 specimens including 11 hepatocellular carcinoma (HCC) tissues, 11 corresponding adjacent tissues, and 11 normal liver tissues. We identified 194 single nucleotide variants (SNVs; including insert and deletion) in 33 liver tissues, and 13 somatic novel mutations were detected, including 7 mutations in the coding region. One of the seven somatic mutations (T7609C, 91.09%) is synonymous, which does not change amino acid coding; the other four somatic mutations (T6115C, 65.74%; G8387A, 12.23%; G13121A, 93.08%; and T14180C, 28.22%) could result in amino acid substitutions, potentially leading to mitochondrial dysfunction. Furthermore, two mutations in tRNA might influence amino acid transportation. Consistent with a previous study, we also found that mtDNA copy number was significantly reduced in HCC tissues. Therefore, we established a mitochondrial genome depletion cell line rho0 and revealed that mtDNA loss reduced proliferation and migration in HCC cells but promoted their resistance to 5-fluorouracil. Our results suggested that somatic mtDNA mutations may cause mitochondrial dysfunction and affect chemoresistance of HCC cells. These new identified somatic mutations may serve as a reference for future studies of cancer mitochondrial genomes. PMID- 29463350 TI - Flight. PMID- 29463348 TI - Long Noncoding RNA FGFR3-AS1 Promotes Hepatocellular Carcinoma Carcinogenesis via Modulating the PI3K/AKT Pathway. AB - Hepatocellular carcinoma (HCC) as one of the most refractory cancers leads to high mortality worldwide. Long noncoding RNAs have been widely acknowledged as important biomarkers and therapeutic targets in HCC. In this study, we investigated the effects of long noncoding RNA FGFR3-AS1 on tumor growth and metastasis in HCC. First, we found that the expression of FGFR3-AS1 was upregulated about threefold in HCC samples and cell lines. We knocked down FGFR3 AS1 in Huh7 and Hep3B cells and found that FGFR3-AS1 knockdown significantly inhibited cell proliferation but induced apoptosis. Moreover, FGFR3-AS1 knockdown led to more HCC cells arrested in the G0 stage. FGFR3-AS1 knockdown significantly inhibited cell migration and invasion. Additionally, we found that FGFR3-AS1 silencing dramatically delayed tumor growth in vivo. We found that, mechanistically, FGFR3-AS1 silencing decreased the activation of the PI3K/AKT signaling pathway. Taken together, our data demonstrated the pro-oncogenic role of FGFR3-AS1 in HCC and suggested that FGFR3-AS1 may serve as a novel biomarker for the diagnosis and therapeutic target for HCC treatment. PMID- 29463351 TI - Risk Factors for Hearing Decrement Among U.S. Air Force Aviation-Related Personnel. AB - INTRODUCTION: The purpose of this study was to analyze historical hearing sensitivity data to determine factors associated with an occupationally significant change in hearing sensitivity in U.S. Air Force aviation-related personnel. METHODS: This study was a longitudinal, retrospective cohort analysis of audiogram records for Air Force aviation-related personnel on active duty during calendar year 2013 without a diagnosis of non-noise-related hearing loss. The outcomes of interest were raw change in hearing sensitivity from initial baseline to 2013 audiogram and initial occurrence of a significant threshold shift (STS) and non-H1 audiogram profile. Potential predictor variables included age and elapsed time in cohort for each audiogram, gender, and Air Force Specialty Code. Random forest analyses conducted on a learning sample were used to identify relevant predictor variables. Mixed effects models were fitted to a separate validation sample to make statistical inferences. RESULTS: The final dataset included 167,253 nonbaseline audiograms on 10,567 participants. Only the interaction between time since baseline audiogram and age was significantly associated with raw change in hearing sensitivity by STS metric. None of the potential predictors were associated with the likelihood for an STS. Time since baseline audiogram, age, and their interaction were significantly associated with the likelihood for a non-HI hearing profile. DISCUSSION: In this study population, age and elapsed time since baseline audiogram were modestly associated with decreased hearing sensitivity and increased likelihood for a non H1 hearing profile. Aircraft type, as determined from Air Force Specialty Code, was not associated with changes in hearing sensitivity by STS metric.Greenwell BM, Tvaryanas AP, Maupin GM.

PMID- 29463352 TI - Precooling and Warm-Up Effects on Time Trial Cycling During Heat Stress. AB - BACKGROUND: Heat stress limits endurance exercise performance. Combining precooling and warm-up prior to endurance exercise in the heat may exploit the benefits of both strategies while avoiding the potential negative consequences of each. This study tested the hypothesis that precooling combined with warm-up improves time trial cycling performance in the heat relative to either treatment alone. METHODS: Nine healthy men completed three 16.1-km time trials in 33 degrees C after: 1) precooling (ice slurry and ice vest) alone (PREC); 2) warm-up alone (WU); or 3) PREC plus WU (COMBO). RESULTS: Tre was lower after PREC compared to WU throughout exercise and lower than COMBO for the first 12 km; COMBO was lower than WU for the first 4 km. Tsk during PREC was lower than COMBO and WU for the first 8 km, and lower in COMBO than WU for the first 4 km. PREC lowered pre-exercise heart rate relative to COMBO and WU (68 +/- 10, 106 +/- 12, 101 +/- 13 bpm, respectively), but it increased similarly during exercise. Local sweat rate (SR) was lower in PREC (0.1 +/- 0.1 mg . cm-2 . min-1) than COMBO (0.5 +/- 0.2 mg . cm-2 . min-1) and WU (0.6 +/- 0.2 mg . cm-2 . min-1) for the first 4 km. Treatments did not differentially affect performance (PREC = 31.9 +/- 1.9 min, COMBO = 32.6 +/- 2.7 min, WU = 33.1 +/- 2.9 min). DISCUSSION: We conclude precooling alone or with warm-up mitigated thermal strain during exercise, but did not significantly improve 16.1-km cycling time trial performance.Al-horani RA, Wingo JE, Ng J, Bishop P, Richardson M.

AB - INTRODUCTION: A loss of 1% or more of bodyweight due to dehydration has a negative effect on cognitive performance, which could critically affect flight safety. There is no mention in the literature concerning the amounts of military pilots' fluid loss during flight. The aim of this study was to quantify fluid loss of pilots during military flight. METHODS: There were 48 aviators (mean age 23.9) from the Israeli Air Force who participated in the study, which included 104 training flights in various flight platforms. Bodyweight, urine specific gravity, and environmental heat strain were measured before and after each flight. Fluid loss was calculated as the weight differences before and after the flight. We used a univariate and one-way ANOVA to analyze the effect of different variables on the fluid loss. RESULTS: The mean fluid loss rate was 462 ml . h-1. The results varied among different aircraft platforms and depended on flight duration. Blackhawk pilots lost the highest amount of fluids per flight, albeit had longer flights (mean 108 min compared to 35.5 in fighter jets). Jet fighter pilots had the highest rate of fluid loss per hour of flight (up to 692 ml, extrapolated). CONCLUSION: Overall, at 11 flights (11%) aircrew completed their flight with a meaningful fluid loss. We conclude that military flights may be associated with significant amount of fluid loss among aircrew.Levkovsky A, Abot Barkan S, Chapnik L, Doron O, Levy Y, Heled Y, Gordon B.

AB - INTRODUCTION: The purpose of this research was to evaluate neuroendocrine and physical performance responses in sailors and Marines undergoing U.S. Navy Survival, Evasion, Resistance, and Escape (SERE) training. METHODS: Participants were 20 men (Age: 25.3 +/- 3.6 yr; Height: 178.1 +/- 6.1 cm; Weight: 83.7 +/- 12.6 kg). Men were further split into high fit (N = 10) and low fit (N = 10) subgroups based on physical fitness test scores. Blood samples were obtained at baseline (T1), stress (T2), and recovery (T3) timepoints, and were analyzed for plasma epinephrine, plasma norepinephrine, plasma dopamine, serum cortisol, serum testosterone, and plasma neuropeptide Y. Vertical jump and handgrip tests were performed at T1 and T2. RESULTS: Stress hormone concentrations were significantly elevated at T2, with a concomitant reduction in testosterone concentrations. NPY concentrations did not increase at T2, but decreased significantly at T3. Subjects maintained performance on vertical jump and handgrip tests from T1 to T2. Significant between group differences were observed in norepinephrine (high fit: 3530.64 +/- 2146.54 pmol . L-1, low fit: 4907.16 +/- 3020.85 pmol . L-1) and NPY (high fit: 169.30 +/- 85.89 pg . ml-1, low fit: 123.02 +/- 88.86 pg . ml-1) concentrations at T3. CONCLUSION: This study revealed that despite significant increases in stress hormone concentrations in all subjects during SERE, fitter subjects exhibited differential hormonal responses during recovery, with quicker return of norepinephrine and NPY to baseline concentrations. This suggests physical fitness level may have a protective effect in recovery from periods of high stress military training.Szivak TK, Lee EC, Saenz C, Flanagan SD, Focht BC, Volek JS, Maresh CM, Kraemer WJ.

AB - INTRODUCTION: The provision of medical care in exploration-class spaceflight is limited by mass, volume, and power constraints, as well as limitations of available skillsets of crewmembers. A quantitative means of exploring the risks and benefits of inclusion or exclusion of onboard medical capabilities may help to inform the development of an appropriate medical system. A pilot project was designed to demonstrate the utility of an early tradespace analysis tool for identifying high-priority resources geared toward properly equipping an exploration mission medical system. METHODS: Physician subject matter experts identified resources, tools, and skillsets required, as well as associated criticality scores of the same, to meet terrestrial, U.S.-specific ideal medical solutions for conditions concerning for exploration-class spaceflight. A database of diagnostic and treatment actions and resources was created based on this input and weighed against the probabilities of mission-specific medical events to help identify common and critical elements needed in a future exploration medical capability. RESULTS: Analysis of repository data demonstrates the utility of a quantitative method of comparing various medical resources and skillsets for future missions. Directed database queries can provide detailed comparative estimates concerning likelihood of resource utilization within a given mission and the weighted utility of tangible and intangible resources. DISCUSSION: This prototype tool demonstrates one quantitative approach to the complex needs and limitations of an exploration medical system. While this early version identified areas for refinement in future version development, more robust analysis tools may help to inform the development of a comprehensive medical system for future exploration missions.Antonsen EL, Mulcahy RA, Rubin D, Blue RS, Canga MA, Shah R.

PMID- 29463356 TI - Augmenting Human Performance in Remotely Piloted Aircraft. AB - INTRODUCTION: An experiment in a program of research supporting the sense-assess augment (SAA) framework is described. The objective is to use physiological measures to assess operator cognitive workload in remotely piloted aircraft (RPA) operations, and provide augmentation to assist the operator in times of high workload. In previous experiments, physiological measures were identified that demonstrate sensitivity to changes in workload. The current research solely focuses on the augmentation component of the SAA paradigm. This line of research uses a realistic RPA simulation with varying levels of workload. METHODS: Recruited from the Midwest region were 12 individuals (6 women) to participate in the experiment. The subjects were trained to perform a surveillance task and a tracking task using RPAs. There was also a secondary task in which subjects were required to answer cognitive probes. A within subjects factorial design was employed with three factors per task. Subjective workload estimates were acquired using the NASA-TLX. Performance data were calculated using a composite scoring algorithm. RESULTS: Augmentation significantly improved performance and reduced workload in both tasks. In the surveillance task, augmentation increased performance from 573.78 to 679.04. Likewise, augmentation increased performance in the tracking task from 749.39 to 791.81. Augmentation was more beneficial in high workload conditions than low workload conditions. DISCUSSION: The increase in performance and decrease in workload associated with augmentation is an important and anticipated finding. This suggests that augmentation should only be provided when it is truly needed, especially if the augmentation requires additional assets and/or resources.Gruenwald CM, Middendorf MS, Hoepf MR, Galster SM.

PMID- 29463357 TI - Point-of-Care Ultrasound for Pulmonary Concerns in Remote Spaceflight Triage Environments. AB - INTRODUCTION: With the development of the commercial space industry, growing numbers of spaceflight participants will engage in activities with a risk for pulmonary injuries, including pneumothorax, ebullism, and decompression sickness, as well as other concomitant trauma. Medical triage capabilities for mishaps involving pulmonary conditions have not been systematically reviewed. Recent studies have advocated the use of point-of-care ultrasound to screen for lung injury or illness. The operational utility of portable ultrasound systems in disaster relief and other austere settings may be relevant to commercial spaceflight. METHODS: A systematic review of published literature was conducted concerning the use of point-of-care pulmonary ultrasound techniques in austere environments, including suggested examination protocols for triage and diagnosis. RESULTS: Recent studies support the utility of pulmonary ultrasound examinations when performed by skilled operators, and comparability of the results to computed tomography and chest radiography for certain conditions, with important implications for trauma management in austere environments. DISCUSSION: Pulmonary injury and illness are among the potential health risks facing spaceflight participants. Implementation of point-of-care ultrasound protocols could aid in the rapid diagnosis, triage, and treatment of such conditions. Though operator dependent, ultrasound, with proper training, experience, and equipment, could be a valuable tool in the hands of a first responder supporting remote spaceflight operations.Johansen BD, Blue RS, Castleberry TL, Antonsen EL, Vanderploeg JM.

PMID- 29463358 TI - Intravestibular Balance and Motion Sickness. AB - INTRODUCTION: A theory is presented to explain the major findings regarding motion sickness and to synthetize current theories concerning its etiology. The theory proposes that an imbalance in the output of the two major organs of the labyrinth-favoring the semicircular canals over the otolith organs-is responsible for most instances of motion sickness as experienced in terrestrial and microgravity environments. METHODS: Strengths and limitations of current theories are first outlined before the different roles of the canals and otoliths in the genesis of motion sickness symptoms are described. RESULTS: The proposed theory is shown to explain a large number of findings and integrate current theories. DISCUSSION: The role of vestibular imbalance in motion sickness may be a consequence of the more general differences between the canals and otoliths in autonomic control.Previc FH.

PMID- 29463359 TI - Prophylactic Ankle Braces and the Kinematics and Kinetics of Half-Squat Parachute Landing. AB - INTRODUCTION: The objective of the study was to investigate the effects of dropping heights and prophylactic ankle braces on ankle joint biomechanics during half-squat parachute landing from two different heights. METHODS: There were 30 male elite paratroopers with formal parachute landing training and more than 2 yr of parachute jumping experience who were recruited for this study. The subjects tested three different ankle brace conditions (no-brace, elastic brace, semirigid brace). Each subject was instructed to jump off a platform from two different heights of 0.4 m and 0.8 m, and land on a force plate in a half-squat posture. The Vicon 3D motion capture system and force plate were used to record and calculate kinematic and kinetic data. RESULTS: Dropping height had a significant effect on peak vertical ground reaction force (vGRF), maximum ankle angular displacement, and time to vGRF. As compared with the no-brace group, use of an elastic ankle brace significantly reduced peak vGRF by 18.57% and both braces significantly reduced the maximal angular displacements of dorsiflexion. The semirigid brace provided greater restriction against maximal angular displacement of inversion. DISCUSSION: The elastic and semirigid ankle braces both effectively restricted motion stability of the ankle joint in the sagittal plane, and the semirigid ankle brace prevented excessive inversion, although the comfort of this device should be improved overall.Wu D, Zheng C, Wu J, Hu T, Huang R, Wang L, Fan Y.

PMID- 29463360 TI - Severe Arthritic Changes Following Acetabular Labral Repair and Femoroplasty in an Air Force Pilot. AB - BACKGROUND: Acetabular labral tears in the hip have become an increasingly common finding in active duty members due to improved diagnostic capabilities. This has led to a dramatic increase in operative management despite a lack of evidence to support clear long-term benefits. Literature review demonstrated overwhelmingly positive short-term outcomes for labral repairs; however, scattered case reports exist demonstrating debilitating outcomes in young patients, ultimately resulting in total hip arthroplasty. CASE REPORT: A 27-yr-old pilot originally presented with groin pain. Initial X-ray demonstrated a CAM lesion of the right hip and subsequent MRA showed an acetabular labral tear. The patient underwent open arthrotomy with labral repair and femoroplasty with minimal improvement in symptoms. Repeat imaging over 2 yr showed early onset osteoarthritis with rapid progression and a recurrent labral tear. Due to the significant progression of osteoarthritis, the patient was given the choice between a repeat labral repair and total hip arthroplasty. The patient elected for hip arthrotomy with labral repair and extensive synovectomy, which yielded minimal improvement in symptoms. DISCUSSION: Acetabular labral tears have become a hot topic in the field of orthopedics as a result of a surge in diagnoses likely due to improvements in imaging, most notably MRAs. This has led to considerable debate regarding how to best manage this condition. The literature overwhelmingly shows positive short term outcomes for surgical management; however, long-term follow-up studies are lacking. The literature has demonstrated multiple case reports resulting in significant complications as a result of these operations, including chondrolysis and eventual need for total hip arthroplasty. Therefore, patient selection is critical as the population tends to be young and active, and the potential complications can be catastrophic. In any case, it is clear that further research is required.Sardon CJ, Resnick ML. Severe arthritic changes following acetabular labral repair and femoroplasty in an air force pilot.

AB - Since the serendipitous discovery of heavy-chain antibodies in Camelidae 20 years ago, the smallest single-domain antigen-binding fragment, known as VHH or nanobody, has received growing attention. In comparison with traditional antibodies, VHHs performs equally high specificity and affinity and low toxicity to targets, and has the ability to inhibit the formation of enzymes and enter the receptor gap. Hence, VHHs has been recently regarded as the highly valued protein and applied in multiple fields, including fundamental research, diagnosis, therapeutics, food science, etc. Today, based on the past achievements, an increasing number of academic and industrial groups begin to explore innovative VHH applications. In this review, we make a thorough retrospect of the unique features and explore novel implementations of VHHs in diverse forms in different fields. In addition, we also propose the potential future issues and problems of VHHs in many fields. PMID- 29463364 TI - Cutting Edge Protein and Carbohydrate-Based Materials for Anticancer Drug Delivery.

AB - The employment of nanoparticles has markedly increased in recent years for different applications such as aerospace technology, electronics, biology, and medicine. The exposure of nanoparticles to humans is inevitable nowadays. Neutrophils act as the predominant phagocytic cells for first-line defense to be recruited to an inflammatory site against xenobiotics. It is important to explore how neutrophils interact with nanoparticles to elicit immune responses. Different types of nanoparticles have been studied to reveal a potential interaction to neutrophils in vitro and in vivo. These mainly include metallic nanoparticles, polymeric nanoparticles, silica nanoparticles, lipid nanoparticles, and fullerenes. A number of investigations have reported the toxicity of nanoparticles induced by neutrophil activation. In this review we discuss data demonstrating recently recognized aspects of inflammation induced by overwhelmed neutrophils after nanoparticle treatment. Besides the dark side of the nanoparticles, some therapeutic nanoparticles are developed and beneficial in treating neutrophil-related diseases such as acute lung injury, vascular inflammation, and bacterial infection. Some nanoparticles can recruit neutrophils around tumor sites for immunotherapy. We also summarize how nanoparticles actively target neutrophils with therapeutic aims. This review provides a broad introduction to nanoparticle interplay with neutrophils and discusses in vitro and in vivo studies in which they have been evaluated.

AB - Graphene has been found to be an excellent heat-conductor due to the high speed of acoustic phonons in its lattice. In this work, we examine in depth a commercial graphene-based waist protector which uses graphene as a heating element. By employing thermal imaging in tandem with Raman microscopy, the thermal characteristics and performance of this device is fully assessed. It will be shown that no pronounced variation in its function is observed up to 3 hours of continuous operation and that the device seems to work effectively as an IR emitter at low power consumption. Temperature fluctuations, associated with a decrease of its electrical resistance are observed after 12 hours uptime and a temperature difference of 15 degrees C was recorded after 5 days of uninterrupted operation. These effects are thought to be due to the loss of graphene/polymer adhesion resulting from thermal fatigue. Overall, it is demonstrated that graphene can indeed be incorporated as an effective and operational thermal heating system in similar biomedical devices.

AB - (Arginine-Glycine-Aspartic)-methoxy polyethylene glycol-(1,2-distearoyl-sn glycero-3-phosphoethanolaMine-N) (abbreviation: RGD-PEG2000-DSPE or RGD-PD) was successfully synthesized and verified by 1H-NMR and MALDI-TOF MS. Polyethylene glycol-poly-L-lysine/RGD-PD/phospholipid/calcium phosphate nanoparticles (PEG PLL/RGD-PD/PL/CaP NPs or MNPs) were prepared using a novel, simple method conducted at room temperature. Transmission electron microscopy (TEM) analysis showed that the MNPs were spheres of uniform size, with a diameter of ~30 nm, and smooth surface. Thermogravimetric analysis (TGA) revealed that the PEG-PLL/RGD PD/PL micelle was packed in the CaP shell. MNPs had little effect on hemolysis, coagulation, cardiac oxidative stress, inflammatory response and DNA damage, indicating negligible cytotoxicity in vitro and in vivo. Experiments in Zebrafish indicated that the MNPs neither affected the survival rate and heartbeat rate, nor induced malformation and apoptosis during embryogenesis. In conclusion, these results demonstrate that the newly-developed MNPs have good biocompatibility and a great potential as drug and gene carrier. PMID- 29463369 TI - Glycyrrhetinic Acid-Modified Norcantharidin Nanoparticles for Active Targeted Therapy of Hepatocellular Carcinoma. AB - Norcantharidin (NCTD), the demethylated analogue of cantharidin, has been confirmed to have a good anti-tumor effect against hepatocellular carcinoma (HCC). However, its use is limited by its poor water solubility and low tumortargeting efficacy. In the present study, an active-targeted drug delivery nanoplatform was designed to deliver NCTD using a glycyrrhetinic acid (GA) decorated copolymer (mPEG-PCL-PEI-GA, MPG). The NCTD-loaded polymeric nanoparticles (MPG/NCTD) formed by self-assembly in water exhibited a mean hydrodynamic diameter of roughly 89 nm. In vitro studies revealed that GA conjugated nanoparticles (AT NPs) had superior cytotoxicity and higher targeting efficacy on HepG2 cells compared to non-conjugated nanoparticles (Non-AT NPs, NAT NPs). Determination of cell apoptosis and cell cycle phase showed that AT NPs resulted in increased cell apoptosis and a distinct increase in the G2 phase (65.30 +/- 3.52%, P < 0.01) and S phase (46.39 +/- 1.39%, P < 0.01). Evaluation of in vivo anti-tumor activity showed that the AT NPs significantly inhibited tumor growth and prolonged survival of tumor-bearing mice. The expression of Ki 67 and CD31 revealed that AT NPs inhibited cell proliferation and resulted in a decreased microvessel density (MVD). The results indicated that NCTD-loaded GA modified nanoparticles may have great potential in HCC-targeted therapy. PMID- 29463370 TI - Exchangeability of FITC-SiO2 Nanoparticles Between Cancer Cells Increases the Range of Drug Delivery. AB - Drug delivery system studies aim to improve nanoparticle (NP) formulation to enable efficient delivery of NPs to tumors. However, NPs must be transported by blood or through direct injection. How NPs leave the circulatory system and how NPs diffuse into a tumor remain unclear, and this uncertainty is a limitation of drug delivery systems. The intimate connection between these questions and metabolism may be related to their biosafety in vivo. Thus, in this study, classical carrier SiO2 NPs were used as typical transport NPs, and fluorescein isothiocyanate (FITC) was used as the representative drug and tracer. As exosome and tunneling nanotubes (TNTs) are the most relevant mechanism for NP transportation and considering the local situation in a tumor, we focused on identifying this phenomenon and investigating TNTs. In conclusion, we effectively demonstrated that NPs can be transferred from cell to cell. Nanotubes may play an important role in this process. PMID- 29463371 TI - Enhanced In Vitro and In Vivo Anticancer Properties by Using a Nanocarrier for Co Delivery of Antitumor Polypeptide and Curcumin. AB - In this paper, a novel pH and redox dual-sensitive nanocarrier loaded with curcumin (Cur) and anticancer polypeptide (AP) was developed for dual targeting mitochondrial and CD44 receptor. The amphiphilic block copolymer was prepared by triphenylphosphonium (TPP)/oligomeric hyaluronic acid (oHA)/disulfide-menthone 1,2-glycerol ketal (SM), hereinafter referred to as TPP-oHSM. The TPP targeted the mitochondria, pH/redox dual-sensitive SM served as a hydrophobic part, and the CD44 receptor targeting oHA worked as a hydrophilic part. The chemical structure of the TPP-oHSM was identified using 1H NMR and FTIR technologies. Cur and AP were loaded into the TPP-oHSM micelles by self-assembly and denoted as C/A@TM. The C/A@TM prepared in this study exhibited an approximately spherical structure, with a mean diameter of 191.3 +/- 3.1 nm and a negative zeta potential of -26.10 +/- 0.45 mV. The in vitro release study and cellular uptake test revealed that the C/A@TM targeted the mitochondria and CD44 receptor, as well as it showed sensitivity towards pH and redox. In addition, the C/A@TM demonstrated satisfactory cytotoxic effects against MDA-MB-231 cells and MCF-7 cells. Finally, the in vivo application of the C/A@TM showed excellent therapeutic effects. The C/A@TM developed in this study exhibited promising multifunctional properties as a co-delivery carrier of polypeptide and chemical drug for an effective clinical therapy for cancer. PMID- 29463372 TI - One-Step Synthesis of DNA Templated Water-Soluble Au-Ag Bimetallic Nanoclusters for Ratiometric Fluorescence Detection of DNA. AB - DNA strands have been used as templates to form different sized silver nanoclusters. Although DNA templated silver nanoclusters (NCs) probes which show outstanding fluorescence properties have been widely applied in chemical sensing and cellular imaging, synthesis of DNA template Au-Ag bimetallic nanoclusters remains a challenge. A facile one-step synthesis method was thus developed in this study to form Au-Ag NCs using C4-ATAT-C4 as template. C4-ATAT-C4 acted as a stabilizer for preventing aggregation of the Au-Ag NCs. The obtained Au-Ag NCs stabilized by C4-ATAT-C4 showed bright fluorescence and high stability. A series of experiments showed that temperature, citrate-citric acid buffer, sequence and concentration of DNA played an important role in the synthesis of fluorescent Au Ag NCs. In addition, a ratiometric fluorescence probe was designed through combining the nucleotide sequence (C4-ATAT-C4) and hybridization sequence in the presence of the double-strand-chelating dye Super SYBR Green (SG). The combination of prepared Au-Ag NCs, Super SG, and perfectly matched DNA emitted fluorescence at 500 and 590 nm, respectively, when the composite was excited at 290 nm. A gastric cancer gene was also selectively detected by our developed ratiometric fluorescence probe. PMID- 29463373 TI - Novel Application of Cell Penetrating R11 Peptide for Diagnosis of Bladder Cancer. AB - OBJECTIVE: As a novel cell-permeable peptide, polyarginine (R11) showed great potential as contrast agent to target bladder cancer (BCa) for therapeutic applications. However, its diagnostic ability and uptake efficiency between BCa and normal bladder tissues is unknown. In this study, we investigated the feasibility of R11 conjugated with fluorescein isothiocyanate (FITC-R11) for detecting BCa in clinical practice. METHOD: FITC-R11 was synthesized and incubated with BCa cell lines (T24, 5637, RT4), normal immortalized human bladder epithelial cell line (SVHUC) and clinical specimens from BCa and benign prostate hyperplasia patients. The uptake efficiency was determined by the mean values of relative FITC intensity. Furthermore, FITC-R11 was intravesically injected into the athymic nude mice bearing orthotopic T24-t tumors and pulmonary metastasis of bladder tumor mice models, the fluorescence intensity of bladder tumors and normal bladder tissues was examined, as well as lung tissues. RESULT: After incubation with FITC-R11, the fluorescence intensity of T24, 5637, RT4 and SVHUC cell line was 64678.56 +/- 9699.27, 46456.22 +/- 2588.06, 33802.02 +/- 429.72 and 17785.01 +/- 1704.36, respectively (P < 0.05). In the athymic nude mice bearing orthotopic T24-t tumors, FITC-R11 showed elevated accumulation in the bladder tumors compared with normal bladder tissues, FITC-R11 was also accumulated in the lung of pulmonary metastasis mice. Moreover, the uptake efficiency of FITC-R11 in patients' BCa tissues was much higher than in normal bladder tissues (6441.95 vs. 1196.92, P < 0.05), as well as the urine samples of BCa patients and benign prostate hyperplasia patients (30250.37 vs. 4948.42, P < 0.05). CONCLUSION: As compared with normal bladder tissue, FITC-R11 is a more specific molecular probe for BCa, and has the potential application in clinical practice. PMID- 29463374 TI - Nano-Vesicles are a Potential Tool to Monitor Therapeutic Efficacy of Carbon Ion Radiotherapy in Prostate Cancer. AB - Exosomes are nano-vesicles that contribute to the effectiveness of many treatments. The aim of this study was to identify profiles of microRNA (miRNA) contained in serum exosomes that are differentially regulated in patients with prostate cancer undergoing carbon ion radiotherapy (CIRT). RNA was extracted from serum exosomes of eight patients with localized prostate cancer before and after CIRT, and miRNA was analyzed by the next generation sequencing. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis showed that the major signaling pathways associated with the proliferation of prostate cancer cells, such as MAPK, PI3K-AKT, mTOR, and AMPK may be implicated in the mechanism of CIRT action. Notably, 57 miRNAs present in serum exosomes were significantly altered after application of CIRT. A high pre-CIRT expression level of specific miRNAs (miR-493-5p, miR-323a-3p, miR-411-5p, miR-494-3p, miR-379-5p, miR-654-3p, miR-409 3p, miR-543, and miR-200c-3p) predicted therapeutic benefit of CIRT (P < 0.05). Post-CIRT expression of miR-654-3p and miR-379-5p was also associated with CIRT efficacy (P < 0.05). These results suggest that the anti-prostate cancer mechanisms elicited by CIRT at the molecular level may involve exosomal miRNAs. Furthermore, specific miRNAs in serum exosomes, particularly miR-654-3p and miR 379-5p, may serve as promising non-invasive biomarkers predicting efficacy of CIRT for prostate cancer. PMID- 29463375 TI - Poly(lactic-co-glycolic acid)/Polycaprolactone Nanofibrous Membranes for High Efficient Capture of Nano- and Microsized Particulate Matter. AB - The incidence of many diseases is closely related to air pollution. Suspended particulate matter of different sizes represents a major source of environmental pollution. Fine particles, especially ultrafine particles smaller than 2.5 MUm, might be more harmful to human health because of their extremely small size, which enables them to penetrate human lungs and bronchi and makes them difficult to filter out. Therefore, the fatal risks associated with PM call for the development of air purification materials with high efficiency and low resistance. In this study, poly(lactic-co-glycolic acid) and polycaprolactone were used to prepare nanofibrous membranes suitable for the efficient capture of particulate matter formed in haze-fog episodes, especially particles smaller than 0.5 MUm. The present nanofibrous membranes exhibit superior filtration efficiency for particulate matter, with a much lower pressure drop compared to typical commercial microfiber air filters. Thanks to the combination of small pore size, high porosity, and robust mechanical properties, the poly(lactic-co-glycolic acid)/polycaprolactone (6:4) composite membrane exhibits a high filtration efficiency of 97.81% and a low pressure drop of 181 Pa. These favorable features, combined with the easy availability and biocompatibility of the component materials, highlight the promising potential of the present nanofibrous membranes for the development of personal wearable air purifiers. PMID- 29463376 TI - Ciclosporin A as a Reversal Agent Against Concurrent Multidrug Resistance in Tumors with Nanobubbles. AB - The purpose of this work was to challenge the multidrug resistance (MDR) in tumor through nanobubbles (NB) co-loaded reversal agent and chemotherapeutic drug layer by layer. The core/shell NB structure contains Doxorubicin (Dox) as anticancer drug in the core and Ciclosporin A (CsA), a cyclic polypeptide composed of 11 amino acids, as a reversal agent in the shell. The drug was designed to work against concurrent MDR processes and was defined as CsA/Dox/NB. HL60/ADM cells with typical high expression of multidrug resistance associated protein 1 (MRP1) were assessed by flow cytometer, 3-(4,5-Dimethylthiazol-2-yl)-2,5 diphenyltetrazolium bromide assays, and Western blot analysis to observe the in vitro and in vivo anticancer efficacy and reversal ability of MDR. Results demonstrated that the function and expression of MRP1 could be successfully inhibited by CsA as a reversal agent from the pharmaceutical preparation, leading to dramatic increase of intracellular concentration of Dox. The accumulation of anticancer drug in the MDR cancer cells enhanced inhibition of cell proliferation through G2/M arrest and tumor growth of nude mice xenograft model. It was therefore concluded that the CsA/Dox/NB can be a promising drug candidate in overcoming tumor MDR. PMID- 29463377 TI - A Portable Multi-Channel Turbidity System for Rapid Detection of Pathogens by Loop-Mediated Isothermal Amplification. AB - This study aimed at developing a portable multi-channel turbidity system (21 cm in length, 15.5 cm in width and 11.5 cm in depth) by real-time loop-mediated isothermal amplification (LAMP) method for rapid detection of pathogens. The developed system herein includes temperature control unit, photoelectric detection unit, turbidity calibration unit, power management unit, human machine unit, communication unit and ARM-based microcontroller. The coefficient of variation for eight channels is less than 0.25% in noise analysis. Legionella bacteria (LEG) and H7 subtype virus (H7) were successively detected by the designed and developed system within 60 minutes. Moreover, its specificity for LEG is satisfactory and its sensitivity for H7 is 10 copies/mL. Besides, this system for point-of-care diagnosis allows a rapid, small size, low cost, and automatic detection with the characteristics of high-efficiency, excellent stability and high uniformity. PMID- 29463378 TI - Single-Nucleotide Polymorphism Genotyping of exoS in Pseudomonas aeruginosa Using Dual-Color Fluorescence Hybridization and Magnetic Separation. AB - Pseudomonas aeruginosa exoS gene contains important replacement (non-synonymous) single-nucleotide polymorphism (SNP) loci, of which mutations in loci 162 (G162A) and 434 (G434C) in exoS greatly affects virulence. The present study aimed to develop an SNP-based classification method for exoS loci (G162A and G434C), using magnetic enrichment polymerase chain reaction, magnetic separation, and dual color fluorescence to provide a technical basis for understanding the T3SS genotypic variation. The two SNP loci in 3 P. aeruginosa standard strains, ATCC27853, ATCC9027, and CMCC10104, were analyzed using this method. The two SNP loci of all these strains were found to be of the wild-type subtype. G values were greater than 0.8 and I values were greater than 3; hence, the classification yielded statistically significant results. In addition, G162A and G434C SNP loci in 21 clinical isolates were analyzed using this method for monitoring clinical mutations. In the G162A and G434C SNP loci, 57.1% and 80.9% of isolates were of the wild-type subtype; 23.8% and 14.3%, mutation subtype; 9.5% and 4.8%, heterozygous subtype, respectively. In a word, SNP genotyping of loci G162A and G434C in exoS was established using magnetic separation and dual-color fluorescence hybridization, and the method was optimized. PMID- 29463379 TI - Peptidomic Analysis of Female Reproductive Tract Secretion to Identify Putative Anti-Infection Peptides in the Female Genital System via Nanotechnologies. AB - The female genital system infections have high-incidence among various gynecological diseases. The role of endogenous peptides in female reproductive tract secretion has been rarely investigated regarding gynecological infections. To identify gynecological infections associated endogenous peptides, a comparative peptidomic profiling of vaginal secretion from sexually mature and perimenopause women was conducted in this study using nanoflow liquid chromatography-tandem mass spectrometer. A total of 3096 peptide fragments originating from 1364 precursor proteins were identified, 102 of which were discrepantly expressed, which included 60 over-expressed peptides and 42 under expressed peptides in the sexually mature group compared with the perimenopause group. 6 differentially expressed bioactive peptides were identified to be related to immunodeficiency virus (HIV) infections, human papillomavirus (HPV) infections, bacterial vaginosis (BV) and vulvovaginal candidiasis (VVC). MUC4, MUC5A, MUC5B, MUC6, MUC17 and MUC19 peptides originating from mucin family were identified to enhance vaginal mucous immunity against infections. Moreover, with remarkable development of biomedical nanotechnology, the identified potential anti-infection peptides in our study will be useful in diagnosis and treatment of gynecological infections, especially when combined with nanoparticles. In conclusion, our findings will fill the gap on peptidomics for female genital system infections and pave the way for future studies about reproductive tract diseases management. PMID- 29463380 TI - Metronidazole-Loaded Polyethyleneimine and Chitosan-Based Liquid Crystalline System for Treatment of Staphylococcal Skin Infections. AB - Staphylococcus aureus is a common gram-positive bacterium of the human skin microbiota. It is also a dangerous pathogen that can cause serious and even lethal skin infections. The topical administration of metronidazole via nanotechnology-based drug delivery systems, such as liquid crystalline systems, can modulate both the drug permeation and activity, decreasing its side effects and increasing the drug potent activity against the gram-positive bacteria. This study aimed at: (1) structurally developing and characterizing a liquid crystalline systems composed of chitosan and polyethyleneimine dispersion as the aqueous phase, oleic acid as the oily phase, and ethoxylated and propoxylated cetyl alcohol as the surfactant (FPC) for metronidazole incorporation (0.5% w/w); (2) evaluating the in vitro release and skin permeation and retention properties of the metronidazole-loaded liquid crystalline systems (FPC-M); (3) investigating the in vitro antibacterial activity of FPC-M against Staphylococcus aureus. Polarised light microscopy indicated that both FPC and FPC-M are hexagonal systems. Rheological, texture, and bioadhesion assays showed that both are elastic and bioadhesive systems. According to the results of the in vitro release, permeation, and retention assays, FPC can modulate metronidazole release and allow metronidazole to stay for a longer time on the skin. The determination of FPC-M activity against Staphylococcus aureus showed that it could target the bacterial cell. In conclusion, the liquid crystalline systems developed in this study can improve the clinical performance of metronidazole in the treatment of staphylococcal skin infections. PMID- 29463381 TI - Photocarcinogenic Risk Associated With Narrowband UV-B Phototherapy: An Epidemiologic Study in a Tertiary Care Hospital. AB - BACKGROUND: The risk of skin cancer in patients treated with narrowband (NB) UV-B phototherapy is not well understood. Although experimental studies have shown that there is a risk, clinical studies have not detected an increased incidence of cancer following treatment. The aim of this study was to determine the incidence of nonmelanoma skin cancer (NMSC) in patients treated with NB UV-B phototherapy at a tertiary care hospital in the Mediterranean area. MATERIAL AND METHODS: We conducted a retrospective chart review of 474 patients who received whole-body NB UV-B phototherapy at our hospital between 2002 and 2016 and identified those diagnosed with NMSC during follow-up. We calculated the corresponding crude and standardized incidence rates and compared these with rates in the general population in a similar geographic area. RESULTS: Of the 474 patients, 193 (40.7%) were men and 281 (59.3%) were women. The mean (SD) follow up period was 5.8 (3) years. The prevalence of NMSC at the end of the study period was 1.9% and the standardized incidence was 108.3 cases per 100 000 patient-years. The SIR of 1.9 in the study group was not significantly different from that of the general population. The number of patients who needed to be treated with NB UV-B phototherapy for 1 case of NMSC to occur was 1900. CONCLUSION: NB UV-B phototherapy does not appear to be associated with an increased risk of NMSC. PMID- 29463382 TI - Clinical and non-clinical factors that predict discharge disposition after a fall. AB - BACKGROUND: Falls can result in injuries that require rehabilitation and long term care after hospital discharge. Identifying factors that contribute to prediction of discharge disposition is crucial for efficient resource utilization and reducing cost. Several factors may influence discharge location after hospitalization for a fall. The aim of this study was to examine clinical and non clinical factors that may predict discharge disposition after a fall. We hypothesized that age, injury type, insurance type, and functional status would affect discharge location. METHODS: This two-year retrospective study was performed at an urban, adult level-1 trauma center. Fall patients who were discharged home or to a facility after hospital admission were included in the study. Data was obtained from the trauma registry and electronic medical records. Logistic regression modeling was used to assess independent predictors. RESULTS: A total of 1,121 fallers were included in the study. 621 (55.4%) were discharged home and 500 (44.6%) to inpatient rehabilitation (IRF)/skilled nursing facility (SNF). The median age was 64 years (IQR: 49-79) and 48.4% (543) were male. The median length of hospital stay was 5 days (IQR: 2.5-8). Increasing age (p < 0.001), length of stay in the ICU (p < 0.001), injury severity (p < 0.001), number of comorbidities (p = 0.038), having Medicare insurance (p = 0.025), having a fracture at any body region (p < 0.001), and ambulation status (p = 0.025) significantly increased the odds of being discharged to IRF/SNF compared to home. The removal of injury severity score and ICU length of stay from the "late/regular discharge" model, to create an "early discharge" model, decreased the accuracy of the prediction rate from 78.5% to 74.9% (p < 0.001). CONCLUSION: A combination of demographic, clinical, social, economic, and functional factors can together predict discharge disposition after a fall. The majority of these factors can be assessed early in the hospital stay, which may facilitate a timely discharge plan and shorter stays in the hospital. PMID- 29463383 TI - Reply. PMID- 29463384 TI - The evaluation of depression in multiple sclerosis using the newly proposed Multiple Sclerosis Depression Rating Scale. AB - Fatigue and depression are frequent symptoms in multiple sclerosis (MS). Both are overlapping and shadowing each other and may impair the quality of life. For detection of depression symptoms in MS, the Multiple Sclerosis Depression Rating Scale (MSDRS) has been proposed recently. Here, we compare the performance of MSDRS in MS patients with and without fatigue to that of established rating scales, i.e. Hospital Anxiety and Depression Scale and Beck Depression Inventory. Twenty-nine MS patients were screened for fatigue and depression symptoms. Patients with fatigue showed significantly higher depression scores compared to patients without fatigue, whereas the number of depressed patients did not differ between the two groups. MSDRS seems to have higher sensitivity to detect severe depression than established rating scales. However, one should keep in mind that such a finding might be due to an increase in false positive cases when using MSDRS. Implementing this scale in future studies might be of help to enhance the understanding of its potential utility. PMID- 29463385 TI - A comparison of methods to determine center of mass during pregnancy. AB - Balance changes during pregnancy likely occur because of mass gains and mass distribution changes. However, to date there is no way of tracking balance through center of mass motion because no method is available to identify of the body center of mass throughout pregnancy. We compared methods for determining segment masses and torso center of mass location. The availability of a method for tracking these changes during pregnancy will make determining balance changes through center of mass motion an option for future pregnancy balance research. Thirty pregnant women from eight weeks gestation until birth were recruited for monthly anthropometric measurements, motion capture analysis of body segment locations, and force plate analysis of center of pressure during quiet standing and supine laying. From these measurements, we were able to compare regression, volume measurement, and weighted sum methods to calculate body center of mass throughout pregnancy. We found that mass changes around the trunk were most prevalent as expected, but mass changes throughout the body (especially the thighs) were also seen. Our findings also suggest that a series of anthropometric measurements first suggested by Pavol et al. (2002), in combination with quiet standing on a force plate, can be used to identify the needed components (segment masses and torso center of mass location in three dimensions) to calculate body center of mass changes during pregnancy. The results of this study will make tracking of center of mass motion a possibility for future pregnancy balance research. PMID- 29463386 TI - Effects of tracking landmarks and tibial point of resistive force application on the assessment of patellar tendon mechanical properties in vivo. AB - The different methods used to assess patellar tendon elongation in vivo may partly explain the large variation of mechanical properties reported in the literature. The present study investigated the effects of tracking landmark position and tibial point of resistive force application during leg extensions in a dynamometer. Nineteen adults performed isometric contractions with a proximal and distal dynamometer shank pad position. Knee joint moments were calculated employing an inverse dynamics approach. Tendon elongation was measured using the patellar apex and either the tibial tuberosity (T) or plateau (P) as tracking landmark. Using P for tracking introduced a bias towards greater values of tendon elongation at all force levels from 100 N to maximum tendon force (TFmax; p < 0.05). The differences between landmarks considering maximum tendon strain were greater at the proximal shank pad position (p < 0.05). Tendon stiffness was lower for P compared with T, but only in intervals up to 50% of TFmax (p < 0.05). The agreement between T and P for stiffness calculated between 50% and TFmax was acceptable with the distal, but poor with the proximal pad position. We demonstrated that using the tibia plateau and not the insertion as tracking landmark clearly affects the assessment of the force-elongation curve of the patellar tendon. However, using a distal point of resistive force application and calculating tendon stiffness between 50% and TFmax seems to yield an acceptable agreement between landmarks. These findings have important implications for the assessment of tendon properties in vivo and cross-study comparisons. PMID- 29463387 TI - The high frequency of autoantibodies in HIV patients declines on antiretroviral therapy. AB - Autoantibodies have been described in samples from HIV positive patients, but the effects of antiretroviral therapy (ART) remain unclear. In a retrospective longitudinal study, we applied clinical assays for autoantibodies to sera collected from 13 HIV positive patients as they began ART with <210 CD4 T cells/MUL and over 2 years on treatment. Twelve of the 13 patients had at least one autoantibody. The frequency peaked before ART (21 from 156 assays) and declined to 8/143 positive reactions after 2 years. As anti-smooth muscle (ASM) antibodies remained common, these assays were applied to HIV patients (n = 67) who had <50 copies HIV RNA/mL plasma after 13 (2-17) years on ART, and healthy controls (n = 55). The frequency of ASM was high in these patients and correlated with levels of total IgG. Hence the high frequency of autoantibodies before ART declined, but did not disappear, with successful therapy. Autoantibody levels may reflect B-cell hyperactivity in patients stable on ART. PMID- 29463388 TI - Vascular inflammation: A call for a specific and sensitive biomarker? PMID- 29463389 TI - Trauma in pregnancy. AB - Trauma is the leading non-obstetric cause of death during pregnancy and approximately 6-8% of all pregnancies are complicated by injury, both accidental and intentional. The initial evaluation and management of the injured pregnant patient often requires a multidisciplinary, collaborative team to provide the optimal outcome for both mother and fetus. It is important to recognize that even minor mechanisms of injury may result in poor outcomes for both fetus and mother. Injured pregnant patients meeting admission criteria experience a progressive increase in the number of complications as well as the number of patients that require delivery. There exists opportunity to identify patients who require admission and provide supportive measures that may reduce the complications of prematurity. Patients that are admitted may benefit from a multidisciplinary approach including on-going care from obstetricians or maternal-fetal medicine physicians. Placental abruption is the most common pregnancy complication, and may occur with even minor mechanisms of injury. Increasing severity of trauma increases the frequency of abruption, admission, delivery, and fetal demise. PMID- 29463390 TI - Managing congenital heart disease in the obstetric patient. AB - OBJECTIVE: Cardiovascular disease is the major cause of pregnancy-related maternal mortality in the United States, and congenital heart disease (CHD) is the most common form of structural heart disease affecting women of childbearing age. Most females born with CHD will reach childbearing age and consider pregnancy. Adult CHD and maternal-fetal medicine (MFM) specialists managing women with CHD should provide preconception counseling, cardiovascular risk assessment prior to pregnancy that estimates maternal and fetal risk, management during pregnancy, and in the peripartum period and also know the potential complications and special circumstances that may occur in the post-partum period. This chapter will review the population at risk, patient risk prior to pregnancy, management during pregnancy, management in the peripartum and post-partum periods, and outline specific cardiovascular complications. The chapter will also briefly review some common or high-risk congenital cardiovascular lesions commonly encountered. CONCLUSION: Management of patients with most forms of CHD encountered during pregnancy requires a multidisciplinary approach and careful team-based care to facilitate safe and appropriate management and pregnancy success. PMID- 29463391 TI - Maternal sepsis. AB - Sepsis is a leading cause of maternal morbidity and mortality in developed and developing nations. Obstetric practitioners should be familiar with guidelines that promote the safe and expeditious recovery of those affected. This article will provide the reader with rational steps to aid in the recovery of such a patient. PMID- 29463393 TI - ? AB - The nutrition care of patients with chronic kidney disease (CKD) remains a central question which is permanently studied. The benefits of a dietary protein restriction are once again enlightened, either by reducing the urea found to be hyperglycemic, thus improving the peripheric insulin sensitivity, or by decreasing phosphorus and FGF23 hormone, whose reductions are respectively associated with nephroprotection and diminution of cardiovascular events. The numerous researches conducted on the gut microbiota also open promising avenues to better understand the role of this ecosystem in CKD. Finally, the interest in incremental haemodialysis is revived, results show it may be associated with less loss of proteins and preservation of residual kidney function. The development of a nutritional score, informative of survival prediction, also offers the possibility to ensure a better follow-up of patients. PMID- 29463394 TI - ? AB - Hypertension is common in patients with chronic renal disease particularly those with diabetes. It is sometimes resistant to the pharmacological treatment. The mineralocorticoid receptor antagonist spironolactone may be indicated here. The mineralocorticoid receptor antagonists have a Class 1, Level A indication for the treatment of heart failure with reduced ejection fraction. There is an associated risk of worsening renal function and of hyperkalemia which does not hinder their clinical benefit. However, an appropriate biological monitoring is warranted, along with potential dose adaptations. Cardiorenal syndrome significantly worses the prognosis of congestive heart failure. The use of ultrafiltration can be effective when conventional treatments failed. Its place in the front line needs to be evaluated. PMID- 29463395 TI - [Cardiovascular protection of diabetic patient with chronic renal disease and particular case of end-stage renal disease in elderly patients]. AB - Type 2 diabetes has an increasing prevalence. Life expectancy is dominated by cardiovascular risk, which is the leading cause of death in these patients. Up to one third of diabetic patients will develop diabetic nephropathy related to micro angiopathy. Renal impairment further increases cardiovascular risk. Reducing cardiovascular morbidity and mortality is a major public health issue, as well as early preventing and managing chronic kidney disease (CKD). Good glycemic control prevents the micro-vascular complications of the disease (retinopathy, nephropathy, etc.) and, more recently recognized through prolonged monitoring of the VADT cohort, prevents cardiovascular complications. Control of blood pressure and dyslipidemia are essential in primary or secondary cardiovascular prevention. In addition, the blockers of the renin-angiotensin system slow down the progression of the MRC. Elderly patients with chronic kidney disease (CKD) form another growing group of the nephrologist daily patient pool. Especially for very elderly patients with comorbidities, the question of favoring conservative treatment rather than starting or pursuing dialysis may arise. Survival and quality of life are indeed not necessarily better in elderly patients undergoing dialysis, complications can occur eventually leading to discontinuation, and are occasionally associated with a feeling of stubbornness. Creation of prognostic score is a useful tool to help the decision-making process. However, dialogue with the patient and his/her family, as well as multidisciplinary collaboration remain fundamentals to determine the most suitable care. PMID- 29463396 TI - [Renal transplantation]. AB - Renal transplantation is the best option for patients with end stage renal failure, since it significantly improves their duration and quality of life. The number of patients waiting for a kidney transplant continues to increase while the overall rate of organ procurement in France is stable. The graft shortage is worsening, as is the waiting time on list. Identifying the causes of this crisis and discussing the various options for addressing the kidney graft shortage is the aim of this talk. Among the solutions: (i) improving identification of potential donors through a national and hospitals policy to promulgate organ donation and understanding better the grounds for refusal; (ii) using infusion machines for all grafts with extended criteria; (iii) developing transplantation programs from deceased donors after cardiac arrest; (iv) developing transplantation programs from living donors. PMID- 29463397 TI - [Metabolic complications of chronic kidney disease]. AB - Patients with Chronic Kidney Disease (CKD) are at risk of various metabolic complications, which can lead to health issues and even be life-threatening if not correctly treated, whereas they can be anticipated. Through clinical cases of patients taken from the daily practice, we propose to look into three of these common complications, namely hypocalcemia, hyperkalemia and metabolic acidosis. From the diagnostic approach to the patient care, these cases provide the opportunity to recall the fundamentals of these disorders and to present the recent literature date enlightening the knowledge related to them. PMID- 29463399 TI - Editorial overview: Cell differentiation and development: New kids in the block new tools and concepts opening new doors in development. PMID- 29463398 TI - ? AB - Erythropoietin (EPO) plays an essential role in the regulation of erythropoiesis. Its production is under the control of the Hypoxia Inducible Factor (HIF) protein whose stability varies according to the oxygen level. During chronic renal failure, EPO deficiency is the main cause of anemia, but other factors such as iron deficiency and inflammatory syndrome are also involved. More recently, it is hypothesized that other factors such an excess of GDF-11 production may be also involved. Thus, beside Epo treatment HIF and GDF-11 are potentially new therapeutic targets in anemia of chronic kidney disease. PMID- 29463400 TI - Foreword. PMID- 29463402 TI - Transcriptome-based identification and characterization of genes commonly responding to five different insecticides in the diamondback moth, Plutella xylostella. AB - When the 3rd instar larvae of the diamondback moth (DBM), Plutella xylostella, were pretreated with sublethal doses (LC10) and then subsequently exposed to lethal doses (LC50) of chlorantraniliprole, cypermethrin, dinotefuran, indoxacarb and spinosad via leaf dipping, their tolerance to insecticides was significantly enhanced. To identify genes that commonly respond to the treatment of different insecticides and are responsible for the tolerance enhancement, transcriptomic profiles of larvae treated with sublethal doses of the five insecticides were compared with that of untreated control. A total of 117,181 transcripts with a mean length of 662bp were generated by de novo assembly, of which 35,329 transcripts were annotated. Among them, 125, 143, 182, 215 and 149 transcripts were determined to be up-regulated whereas 67, 45, 60, 60 and 38 genes were down regulated following treatments with chlorantraniliprole, cypermethrin, dinotefuran, indoxacarb and spinosad, respectively. Gene ontology (GO) analysis of differentially expressed genes (DEGs) revealed little differences in their GO profiles between treatments with different insecticides except for spinosad. Finally, the DEGs commonly responding to all insecticides were selected for further characterization, and some of their over-transcription levels were confirmed by quantitative PCR. The most notable examples of commonly responding over-transcribed genes were two cytochrome P450 genes (Cyp301a1 and Cyp9e2) and nine cuticular protein genes. In contrast, several genes composing the mitochondrial energy generation system were significantly down-regulated in all treated larvae. Considering the distinct structure and mode of action of the five insecticides tested, the differentially expressed genes identified in this study appear to be involved in general chemical defense at the initial stage of intoxication. Their possible roles in the tolerance/resistance development were discussed. PMID- 29463403 TI - Metabolisation of thiamethoxam (a neonicotinoid pesticide) and interaction with the Chronic bee paralysis virus in honeybees. AB - Pathogens and pesticides are likely to co-occur in honeybee hives, but much remains to be investigated regarding their potential interactions. Here, we first investigated the metabolisation kinetics of thiamethoxam in chronically fed honeybees. We show that thiamethoxam, at a dose of 0.25ng/bee/day, is quickly and effectively metabolised into clothianidin, throughout a 20day exposure period. Using a similar chronic exposure to pesticide, we then studied, in a separate experiment, the impact of thiamethoxam and Chronic bee paralysis virus (CBPV) co exposure in honeybees. The honeybees were exposed to the virus by contact, mimicking the natural transmission route in the hive. We demonstrate that a high dose of thiamethoxam (5.0ng/bee/day) can cause a synergistic increase in mortality in co-exposed honeybees after 8 to 10days of exposure, with no increase in viral loads. At a lower dose (2.5ng/bee/day), there was no synergistic increase of mortality, but viral loads were significantly higher in naturally dead honeybees, compared with sacrificed honeybees exposed to the same conditions. These results show that the interactions between pathogens and pesticides in honeybees can be complex: increasing pesticide doses may not necessarily be linked to a rise in viral loads, suggesting that honeybee tolerance to the viral infection might change with pesticide exposure. PMID- 29463401 TI - Niche signals and transcription factors involved in tissue-resident macrophage development. AB - Tissue-resident macrophages form an essential part of the first line of defense in all tissues of the body. Next to their immunological role, they play an important role in maintaining tissue homeostasis. Recently, it was shown that they are primarily of embryonic origin. During embryogenesis, precursors originating in the yolk sac and fetal liver colonize the embryonal tissues where they develop into mature tissue-resident macrophages. Their development is governed by two distinct sets of transcription factors. First, in the pre macrophage stage, a core macrophage program is established by lineage-determining transcription factors. Under the influence of tissue-specific signals, this core program is refined by signal-dependent transcription factors. This nurturing by the niche allows the macrophages to perform tissue-specific functions. In the last 15 years, some of these niche signals and transcription factors have been identified. However, detailed insight in the exact mechanism of development is still lacking. PMID- 29463405 TI - Resistance risk assessment for fluazinam in Sclerotinia sclerotiorum. AB - In the current study, sensitivity distribution of Sclerotinia sclerotiorum populations to fluazinam was determined using 103 strains collected from the fields of Jiangsu Province of China in 2016-2017 and the resistance risk of fluazinam was assessed. The average EC50 (50% effective concentration) values and MIC (minimum inhibitory concentration) values of 103 S. sclerotiorum strains against fluazinam were 0.0073+/-0.0045MUg/ml and <0.3MUg/ml for mycelial growth, respectively. Nine mutants with low resistance level were obtained from wild type sensitive strains exposed on PDA medium amended with fluazinam and the resistance was stable after their ten transfers on PDA without the fungicide. Compared with the parental strains, the nine fluazinam-resistant mutants decreased in mycelial growth, sclerotial production, pathogenicity and were more sensitive to 0.7M NaCl. In addition, cell membrane permeability of resistant mutants was higher than that of their parental strains. Cross resistance assay showed that there was no cross-resistance between fluazinam and fludioxonil, dimetachlone, prochloraz, tebuconazole, azoxystrobin, or procymidone in S. sclerotiorum. The above results indicated that there was a low resistance risk for fluazinam in S. sclerotiorum. However, the sensitivity of all fluazinam-resistant mutants to fludioxonil decreased. Sequencing alignment results showed that there were no mutations in the two-component histidine kinase gene (Shk1) of the resistant mutants and the expression levels of Shk1 of three resistant mutants were significantly up regulated while others were almost the same as their parental strains. These results will contribute to evaluating the resistance risk of fluazinam for management of diseases caused by S. sclerotiorum and further increase our understanding about the mode of action of fluazinam. PMID- 29463404 TI - Cytotoxicity of chemical constituents from Torricellia tiliifolia DC. on Spodoptera litura (SL-1) cells. AB - In this study, we evaluated cytotoxicity of chemicals isolated from Torricellia tiliifolia DC. on Spodoptera litura (SL-1) cell line. Among the isolated compounds, 4-hydroxy-3-methoxycinnamaldehyde, 3,5-dimethoxy-4 hydroxycinnamaldehyde, and syringaresinol inhibited SL-1 cell survival in both dose- and time-dependent manners. Meanwhile, the in vivo insecticidal activity test revealed that 4-hydroxy-3-methoxycinnamaldehyde and 3,5-dimethoxy-4 hydroxycinnamaldehyde showed obvious insecticidal activities. These two compounds exhibited toxicity to SL-1 cells by inducing cellular morphological changes including shape change, cell shrinkage, vacuolation, cell membrane blebbing and chromatin condensation and apoptosis. 4-hydroxy-3-methoxycinnamaldehyde and 3,5 dimethoxy-4-hydroxycinnamaldehyde showed the most effect on mitochondrial membrane depolarization at 24h and 72h respectively and induced the apoptosis at a late time point 72h. Our results suggest that 4-hydroxy-3-methoxycinnamaldehyde and 3,5-dimethoxy-4-hydroxycinnamaldehyde inhibit SL-1 survival by inducing apoptosis. PMID- 29463406 TI - Chlorpyrifos-induced parkinsonian model in mice: Behavior, histopathology and biochemistry. AB - INTRODUCTION: The aim of this study was to investigate the protective effect of caffeic acid phenethyl ester (CAPE) on Paraoxonase (PON1) activity, and levels of lipid profile, total sialic acid (TSA), total antioxidant capacity (TAC) and total oxidant capacity (TOC) in the plasma and brain tissue of mice with chlorpyrifos-ethyl (CPF)-induced Parkinson. MATERIAL AND METHOD: In the study, 35 male Swiss albino mice were divided into 5 groups including equal number of mice as follows; intraperitoneal injection of saline for mice in control (C) group, subcutaneous injection of 80mg/kg CPF for CPF group, intraperitoneal injection of 10MUmol/kg CAPE for CAPE group, subcutaneous injection of 80mg/kg CPF and intraperitoneal injection of 10MUmol/kg CAPE for CPF+CAPE group and intraperitoneal injection of 10% ethanol diluted in physiological saline solution for 21days for ethanol (E) group. All the mice were fed with normal feed and tap water ad libitum. At the end of the study, PON1 activity, lipid profile (except for brain), and TSA, TAC and TOC levels in the plasma and brain tissue were analyzed. Tissue samples of brain substantia nigra were evaluated histopathologically. RESULTS: Levels of plasma TAC, high density lipoprotein (HDL) and PON1 activity were statistically lower in CPF group than the other groups (P<0.001). Also, levels of plasma TOC, TSA, total cholesterol, triglycerides, low density lipoprotein (LDL) and very low density lipoprotein (VLDL) were statistically higher in CPF group than the other groups(P<0.001). PON1 activity and level of TAC were significantly lower in brain tissue of CPF groups (P<0.001). In addition, TOC and TSA levels were significantly higher in brain tissue in CPF group (P<0.001). CONCLUSION: In conclusion, CAPE showed a protective effect on PON1 activity and levels of lipid profile, TSA, TAC and TOC in plasma and brain tissue and prevented the neurodegenerations in brain tissue in CPF-induced Parkinson's disease. PMID- 29463407 TI - Effect of genetic polymorphism of human CYP2B6 on the metabolic activation of chlorpyrifos. AB - Chlorpyrifos (CPS) is a broad-spectrum organophosphate insecticide that is neurotoxic in humans. Chlorpyrifos oxon (CPO) is a toxic metabolite of CPS that is produced by CYP2B6. In this study, we examined the variability of CPS metabolism resulting from single-nucleotide polymorphisms in CYP2B6. Wild-type CYP2B6 (CYP2B6.1) and two variants each with a single amino acid substitution: CYP2B6.5 (R487C) and CYP2B6.8 (K139E) were co-expressed together with human NADPH dependent cytochrome P450 reductase in Escherichia coli (E. coli). Both of the CYP2B6 variants were successfully expressed in E. coli. The conversion of CPS to CPO by the CYP2B6 variants was analyzed with high-performance liquid chromatography. Km and Vmax of the reaction by CYP2B6.1 were 18.50+/-2.94MUM and 17.07+/-1.15mol/min/mol P450, respectively. The CYP2B6 variants produced CPO with the following kinetic parameters: Km for CYP2B6.5 and CYP2B6.8 were 20.44+/-6.43 and 44.69+/-9.97MUM, respectively; and Vmax were 1.10+/-0.10 and 1.77+/ 0.26mol/min/mol P450, respectively. These results indicate that the amino acid substitutions in the CYP2B6 variants suppressed the metabolic activation of CPS. CYP2B6 variants have altered capacity to bioactivate CPF and may affect individual susceptibility of CPF. PMID- 29463408 TI - Synthesis, characterization and efficacy of silver nanoparticles against Aedes albopictus larvae and pupae. AB - Silver nanoparticles have been studied in a wide range of medical and entomological research works due to their eco-friendly aspects. In our study salicylic acid (SA) and its derivative, 3,5-dinitrosalicylic acid (DNS), were used in a one-step synthesis of silver nanoparticles (AgNPs). First, UV-vis absorption spectroscopy was used to detect the formation of AgNPs. Second, the synthesized nanoparticles were characterized using scanning electron microscope, transmission electron microscope; energy-dispersive spectroscopy, X-ray diffraction analysis and Fourier transform infrared spectroscopy. I, II, III and IV Instar larvae and pupae of Ae. Albopictus were exposed to various concentrations of SA, DNS and synthesized AgNPs for 24h to evaluate the larvicidal and pupicidal effect. In larvicidal bioassay of SA, moderate mortality was observed at 180ppm against Ae. Albopictus with LC50 values of 86, 108, 135 and 141ppm for instar larvae I, II, III and IV, respectively. Synthesized AgNPs showed highest mortality rate at 12ppm and the LC50 values of SAAgNPs were 1.2ppm (I), 1.4ppm (II), 1.8ppm (III), 2.0ppm (IV) and 1.4ppm (pupae). Whereas LC50 values of DNSAgNPs were 1.2ppm (I), 1.5ppm (II), 1.8ppm (III) 2.3ppm (IV) and 1.4ppm (pupae). Moreover, the investigations toward the systemic effect of the tested substances on the fourth instar larvae of Ae. albopictus was evaluated and the levels of total proteins, esterases, acetylcholine esterase, and phosphatase enzymes were found to be significantly decreased as compared with the control. These results highlight that SA-AgNPs and DNS-AgNPs are potential tools to control larval populations of mosquito. PMID- 29463409 TI - Sublethal effects of sulfoxaflor on biological characteristics and vitellogenin gene (AlVg) expression in the mirid bug, Apolygus lucorum (Meyer-Dur). AB - The mirid bug, Apolygus lucorum (Meyer-Dur) has evolved the resistance towards some traditional insecticides, especially pyrethroids and organophosphates. Sulfoxaflor, as a novel insecticide, is used for control of sap-feeding insects, like A. lucorum. Therefore, it is necessary to determine the acute toxicity and the potential sublethal effects of sulfoxaflor in A. lucorum. Here, the LD50 value of sulfoxaflor against A. lucorum was assayed as 3.347ng/adult at 48h via topical application. Besides, the effects of a sublethal dose (LD15) of sulfoxaflor on biological characteristics of A. lucorum were estimated by comparison of the life table parameters. The longevities and fecundity of parent generation did not exhibited significant difference between both control and treatment groups after exposure to LD15 dose of sulfoxaflor (0.568ng/adult) for 48-h. However, the parameters reflecting their progeny G1 generation population dynamics, including the intrinsic rate of increase (ri), the finite rate of increase (lambda), the mean generation time (T), the net reproductive rate (R0) and gross reproduction rate (GRR) significantly reduced in the treatment group compared to the control. Furthermore, the expression level of AlVg mRNA significantly decreased by 43.8% in the progeny whose parents were treated with LD15 dose of sulfoxaflor in comparison with the control transgenerational female adults. These results suggested that sublethal dose of sulfoxaflor adversely affect the development and reproduction of transgenerational A. lucorum. The downregulation of AlVg might have negative impacts on the fecundity of A. lucorum. PMID- 29463410 TI - Alterations of mitochondrial electron transport chain and oxidative stress induced by alkaloid-like alpha-aminonitriles on Aedes aegypti larvae. AB - Aedes aegypti mosquitoes are responsible for dengue, chikungunya, and Zika virus transmission in tropical and subtropical areas around the world. Due to the absence of vaccines or antiviral drugs for human treatment, the majority of control strategies are targeted at Ae. aegypti elimination. Our research on mosquito control insecticidal agents has previously shown that the alkaloid girgensohnine and its analogues (alpha-aminonitriles) present in vitro acetylcholinesterase inhibition and in vivo insecticidal activity against Ae. aegypti. However, acetylcholinesterase inhibition may not be the only mechanism of action behind these effects. On this basis, the principal aim of this study was to elucidate the possible action mode of four alpha-aminonitriles on Ae. aegypti by studying other important enzymatic targets, such as mitochondrial electron transport chain complexes, catalase, and superoxide dismutase, key oxidative stress enzymes. Mitochondria were isolated from Ae. aegypti larvae by differential centrifugation, stored at -70 degrees C, and fragmented using ultrasound for 10min. The effects of alpha-aminonitriles (1 to 4) over enzymatic activities were evaluated using concentrations of 8nM, 2MUM, 8MUM, and 40MUM. Results indicated that alpha-aminonitriles caused significant NADH dehydrogenase and succinate oxidase inhibition (~44% at the highest concentration tested). Succinate dehydrogenase and cytochrome c oxidase activities were found to increase (162% and 106% at 40MUM, respectively). It was also observed that these compounds produced catalase inhibition and thus prevented H2O2 reduction, which induced the formation of reactive oxygen species (ROS). Moreover, NBT assay showed that compounds 3 and 4 (with 2-(pyrrolidin-1-yl) acetonitrile as substituent) increased by approximately 50% the O2?- concentration in the mitochondrial respiratory chain. It was concluded that the tested compounds act as complex I inhibitors by blocking electron transport and causing electron leak, possibly between complex I and III. Furthermore, alpha-aminonitriles inhibited catalase activity; compounds 1 and 2 (with piperidine fragment) inhibited glutathione reductase activity and further promoted the accumulation of ROS, which probably induced oxidative stress. PMID- 29463411 TI - Betanin reduces organophosphate induced cytotoxicity in primary hepatocyte via an anti-oxidative and mitochondrial dependent pathway. AB - Organophosphates (OP) are potent pesticide commonly utilized in agricultural and domestic use. However, plentitude of data represent their side effects in different body tissues. We attempted to study whether betanin (a natural pigment) is able to mitigate some OPs-induced hepatotoxicity in primary rat hepatocytes. Cell viability, lactate dehydrogenase (LDH) leakage, reactive oxygen species (ROS) formation, lipid peroxidation (LPO), glutathione (GSH) depletion and mitochondrial depolarization were tested as toxicity markers. The outcomes revealed that betanin (25MUM) significantly increased cell viability, plummeted ROS formation and LPO, restored cellular GSH reservoirs and protected mitochondria after chlorpyrifos (CPF) (300MUM), diazinon (DZN) (600MUM) and dichlrovos (DDVP) (400MUM) treatment. Taken together, all data suggests the potential protective role of betanin in OPs-induced hepatotoxicity in which the mechanism appears to be inhibition of ROS formation and mitochondrial protection. PMID- 29463412 TI - Omethoate treatment mitigates high salt stress inhibited maize seed germination. AB - Omethoate (OM) is a highly toxic organophophate insecticide, which is resistant to biodegradation in the environment and is widely used for pest control in agriculture. The effect of OM on maize seed germination was evaluated under salt stress. Salt (800mM) greatly reduced germination of maize seed and this could be reversed by OM. Additionally, H2O2 treatment further improved the effect of OM on seed germination. Higher H2O2 content was measured in OM treated seed compared to those with salt stress alone. Dimethylthiourea (DTMU), a specific scavenger of reactive oxygen species (ROS), inhibited the effect of OM on seed germination, as did IMZ (imidazole), an inhibitor of NADPH oxidase. Abscisic acid (ABA) inhibited the effect of OM on seed germination, whereas fluridone, a specific inhibitor of ABA biosynthesis, enhanced the effect of OM. Taken together, these findings suggest a role of ROS and ABA in the promotion of maize seed germination by OM under salt stress. PMID- 29463413 TI - A genomic approach to identify and monitor a novel pyrethroid resistance mutation in the redlegged earth mite, Halotydeus destructor. AB - Resistance mechanisms are typically uncovered by identifying sequence variation in known candidate genes, however this strategy can be problematic for species with no reference data in known relatives. Here we take a genomic approach to identify resistance to pyrethroids in the redlegged earth mite, Halotydeus destructor, a member of the Penthalidae family of mites that are virtually uncharacterized genetically. Based on shallow genome sequencing followed by a genome assembly, we first identified contigs of the H. destructor parasodium channel gene. By linking variation in this gene to known resistant phenotypes, we located a single nucleotide polymorphism in resistant mites. This polymorphism results in a leucine (L) to phenylalanine (F) amino acid substitution in the II6 region (predicted) of the gene (L1024F). This novel mutation has not previously been linked to pyrethroid resistance, although other polymorphisms have been identified in the two-spotted spider mite, Tetranychus urticae at the same locus (L1024V). The sequencing approach was successful in generating a candidate polymorphism that was then validated using laboratory bioassays and field surveys. A high throughput Illumina-based sequencing diagnostic was developed to rapidly assess resistance allele frequencies in pools of mites sourced from hundreds of populations across Australia. Resistance was confirmed to be widespread in the southern wheatbelt region of Western Australia. Two different resistance mutations were identified in field populations, both resulting in the same amino acid substitution. The frequency and distribution of resistance amplicon haplotypes suggests at least two, and probably more independent origins of resistance. PMID- 29463415 TI - Endocrinology of prostate cancer. PMID- 29463414 TI - Natural meroterpenoids isolated from the plant pathogenic fungus Verticillium albo-atrum with noteworthy modification action against voltage-gated sodium channels of central neurons of Helicoverpa armigera. AB - A new meroterpenoid, named acetoxydehydroaustin A (1) and the known meroterpenoid austin (2) were isolated from the plant pathogenic fungus Verticillium albo atrum. Their structures were established based on general spectroscopic techniques and the relative configuration of compound 1 was determined by single crystal X-ray diffraction analysis. We first investigated and identified their significant electrophysiological effects on the gating kinetics of voltage-gated sodium channels in central neurons acutely dissociated from Helicoverpa armigera using whole-cell patch clamp technique. Similar to the effects of pyrethroids on sodium late currents, both compounds produced concentration-dependent modification of sodium channels, prolonging the kinetics of channel inactivation to generate large persistent late currents during depolarization. However, different from the effects of tefluthrin and deltamethrin on sodium channels, two meroterpenoids did not induce tail currents during deactivation. Compounds 1 and 2 also caused depolarizing shifts in the voltage dependence of channel activation. The V0.5 shifted about 5.02mV and 6.32mV in the depolarizing direction by 50MUM 1 and 50MUM 2. The V0.5 of voltage-dependent inactivation shifted about 11.42mV and 11.62mV respectively in the hyperpolarizing direction by 50MUM 1 and 100MUM 2. In addition, they prolonged the time course of recovery from fast-inactivation for sodium channels. The effects of two compounds on the voltage-dependent gating substantially increased the size of sodium window currents. The overlapped area of window currents increased about 89.69% and 44.51% respectively by 10MUM compound 1 and 10MUM compound 2. These findings show that both compounds have effects on sodium channel activation, inactivation and window currents. The voltage-gated sodium channels in central neurons of H. armigera are the target sites of two meroterpenoid natural products. PMID- 29463416 TI - Irradiation of rainbow trout at early life stages results in a proteomic legacy in adult gills. Part A; proteomic responses in the irradiated fish and in non irradiated bystander fish. AB - Exposure to a single 0.5 Gy X-ray dose of eggs at 48 h after fertilisation (48 h egg), eyed eggs, yolk sac larvae (YSL) and first feeders induces a legacy effect in adult rainbow trout. This includes the transmission of a bystander effect to non-irradiated adult trout which had swam with the irradiated fish. The aim of this study was to investigate this legacy by analysing the gill proteome of these irradiated and bystander fish. Irradiation at all of the early life stages resulted in changes to proteins which play a key role in development but are also known to be anti-tumorigenic and anti-oxidant: upregulation of haemoglobin subunit beta (48 h egg), haemoglobin, serum albumin 1 precursor (eyed eggs), clathrin heavy chain 1 isoform X10 (eyed eggs and first feeders), and actin related protein 2/3 complex subunit 4 (first feeders), downregulation of pyruvate dehydrogenase, histone 1 (48 h egg), triosephosphate isomerase (TPI), collagen alpha-1(1) chain like proteins (YSL), pyruvate kinase PKM-like protein (YSL and first feeders), ubiquitin-40S ribosomal proteins S27 and eukaryotic translation initiation factor 4 A isoform 1B (first feeders). However irradiation of YSL and first feeders (post hatching early life stages) also induced proteomic changes which have a complex relationship with tumorigenesis or cancer progression; downregulation of alpha-1-antiprotease-like protein precursor, vigilin isoform X2 and nucleoside diphosphate kinase (YSL) and upregulation of hyperosmotic glycine rich protein (first feeders). In bystander fish some proteomic changes were similar to those induced by irradiation: upregulation of haemoglobin subunit beta (48 h egg), haemoglobin (eyed eggs), actin-related protein 2/3 complex subunit 4, hyperosmotic glycine rich protein (first feeders), and downregulation of alpha-1 antiprotease-like protein, vigilin isoform X2, nucleoside diphosphate kinase (YSL), pyruvate kinase PKM-like protein and ubiquitin-40S ribosomal protein S27a like (first feeders). Other proteomic changes were unique to bystander fish; downregulation of TPI, ubiquitin-40S ribosomal protein S2 (eyed egg), cofilin-2, cold-inducible RNA-binding protein B-like isoform X3 (YSL) and superoxide dismutase (first feeder), and upregulation of haemoglobin subunit alpha, collagen 1a1 precursor, apolipoprotein A-1-1 and A-1-2 precursor (first feeders). These bystander effect proteomic changes have been shown to be overwhelmingly anti tumorigenic or protective of the fish gill. PMID- 29463417 TI - MRI as a biomarker for mild neonatal encephalopathy. AB - Historically, there has been limited neuro-imaging data acquired on infants with mild neonatal encephalopathy (NE). This likely reflects the traditional assumption that these infants had a universally good prognosis. As new evidence has emerged challenging this assumption, there has been a renewed interest in the neuro-imaging findings of these infants. To date, magnetic resonance imaging (MRI) studies in infants with mild NE have demonstrated abnormalities in 20-40% of cases suggestive that the injury occurs during the peripartum period with a predominant watershed pattern of injury. The severity of the injury on MRI in infants with mild NE varies, but includes patterns of injury that have been associated with long-term neuro-developmental impairment. PMID- 29463418 TI - Amount and distribution of benthic marine litter along Sardinian fishing grounds (CW Mediterranean Sea). AB - Reports of marine litter pollution first appeared in scientific literature of the early 1970s; yet, more than 40 years later, no rigorous estimates exist of the amount of litter existing in the marine environment. To cope with this global urgency, this study reports the status of marine litter abundance along fishing grounds surrounding the island of Sardinia (CW Mediterranean Sea; FAO Geographical Sub-Area 11) through three years of trawl surveys. A total of 302 hauls, covering a total of 18.4 km2 of trawled surface were carried out in the framework of the MEDITS campaign, at depths comprised between 0 and 800 m. A total of 918 items were collected and sorted, with the highest concentration observed above 200 m depth. Overall, plastic was the dominant component of litter, followed by glass and metal. Comparing our results with other areas from the Mediterranean basin, Sardinian waters showed a lower impact, possibly as a consequence of multiple factors such as the lower human population density and the low flow of the main rivers, among others. In addition, fishermen behaviour with respect to marine litter was investigated by mean of anonymous questionnaires, emphasizing the necessity to further develop management policies and infrastructures supporting litter disposal. PMID- 29463419 TI - Influence of the grade on the variability of the mechanical properties of polypropylene waste. AB - The prior properties of recycled polypropylene depend on the origin of waste deposits and its chemical constituents. To obtain specific properties with a predefine melt flow index of polypropylene, the suppliers of polymer introduce additives and fillers. However, the addition of additives and/or fillers can modify strongly the mechanical behaviour of recycled polypropylene. To understand the impact of the additives and fillers on the quasi-static mechanical behaviour, we consider, in this study, three different recycled polypropylenes with three different melt flow index obtained from different waste deposits. The chemical constituents of the additives and filler contents of the recycled polypropylenes are determined through thermo-physico-chemical analysis. Tensile and bending tests performed at different strain rates allow identifying the mechanical properties such as the elastic modulus, the yield stress, the maximum stress, and the failure mechanisms. The results obtained are compared with non-recycled polypropylene and with few researches to explain the combined effect of additives. Finally, a post-mortem analysis of the samples was carried out to make the link between the obtained mechanical properties and microstructure. PMID- 29463420 TI - Comparison of the effectiveness of orthotic intervention, kinesiotaping, and paraffin treatments in patients with carpal tunnel syndrome: A single-blind and randomized controlled study. AB - PURPOSE: The aim of the study was to compare different conservative treatments in patients with carpal tunnel syndrome (CTS). STUDY DESIGN: A single-blind randomized controlled study. METHODS: Patients (n = 169) diagnosed with mild or moderate CTS were screened; 110 met study requirements. The patients were randomized into 3 groups. The control (CON) comparison provided to all patients was a fabricated night orthotic which held the wrist in a neutral position. The second group received adjunctive kinesiotaping (KIN) and the third group received paraffin (PARA). All patients were evaluated clinically, electrophysiologically, and ultrasonographically before treatment and at 3 weeks, 3 months, and 6 months. RESULTS: There were 36 patients in CON, 37 in KIN, and 37 in PARA. Pain reduction in KIN was better than the other groups at 3 weeks (mean difference [MD] in CON 2.4 +/- 2.5, KIN 3.7 +/- 2.0, PARA 2.7 +/- 2.3; P < .01) and 6 months (MD in CON 3.4 +/- 3.0, KIN 4.9 +/- 3.1, PARA 3.7 +/- 2.9; P < .05). KIN pain reduction was better than CON at 3 months (MD in CON 3.8 +/- 2.8, KIN 5.0 +/- 2.5; P < .05). Reduction of the cross-sectional area of median nerve at the level of radioulnar joint was greater for KIN than CON at 3 weeks (MD in CON 0.0 +/- 0.5, KIN 0.3 +/- 0.7; P < .01) than PARA at 3 months (MD in KIN 0.3 +/- 0.8, PARA 0.0 +/- 0.8; P < .05) and both groups at 6 months (MD in CON 0.1 +/- 0.8, KIN 0.5 +/- 0.9, PARA 0.0 +/- 1.0 P < .05). CONCLUSION: Adding KIN to night use of an orthotic was more effective in achieving symptomatic and structural improvements than either the orthotic alone or adjunctive use of paraffin in patients with mild and moderate CTS. PMID- 29463421 TI - Complications of herpes zoster in immunocompetent older adults: Incidence in vaccine and placebo groups in two large phase 3 trials. AB - BACKGROUND: An adjuvanted herpes zoster (HZ) subunit vaccine, HZ/su, demonstrated high efficacy against HZ and postherpetic neuralgia (PHN) in two randomized, observer-blind, placebo-controlled trials in adults aged >=50 and >=70 years (ZOE 50 and ZOE-70, respectively). METHODS: Data from ZOE-50 and ZOE-70 trials were analyzed to evaluate the efficacy of HZ/su against mortality, hospitalizations, and non-PHN complications of HZ including HZ-associated vasculitis, stroke, and disseminated, ophthalmic, neurologic, and visceral diseases. RESULTS: In the pooled ZOE-50/ZOE-70 analysis, 1 of 32 HZ/su recipients (3.1%) and 16 of 477 placebo recipients (3.4%) with a confirmed HZ episode had complications other than PHN. Efficacy against HZ-related complications was 93.7% (95% confidence interval, 59.5-99.9%) in adults aged >=50 years and 91.6% (43.3-99.8%) in adults >=70 years. Five HZ-related hospitalizations, all in placebo recipients, and no HZ-related deaths were reported. CONCLUSIONS: HZ/su reduces the risk of HZ associated complications in older adults (NCT01165177; NCT01165229). PMID- 29463422 TI - Molecular imaging should have played a role. PMID- 29463423 TI - [Is celecoxib a safe alternative for the Fernand Widal syndrome?] AB - The Fernand Widal syndrome is a set of associations between asthma, nasal polyposis and aspirin sensitivity. Selective cyclo-oxygenase 2 (COX 2) inhibitors are recognized as being a therapeutic alternative in cases needing analgesic or anti-inflammatory treatment. In a retrospective study, we have compiled data concerning oral provocation tests (OPT) undertaken with celecoxib, one of most the selective COX 2 inhibitors, in eight patients with the Fernand Widal syndrome. They were compared with twenty-seven control patients with sensitivity to aspirin or non-steroidal anti-inflammatories, manifesting as asthma, urticaria or rhino-conjunctivitis. Four patients with the Fernand Widal syndrome developed bronchospasm after taking the usually recommended daily dose of celecoxib while all the control patients tolerated it. The Fernand Widal patients who reacted during the OPT had a lower threshold of reactivity to aspirin, a more severe reaction with aspirin, and/or more severe asthma. In patients with the Fernand Widal syndrome, celecoxib is not always a possible alternative to non-steroidal anti-inflammatory drugs. Its introduction must be carried out in a hospital environment under medical supervision.

AB - Comparability between CMV assays could be facilitated by the first WHO International Standard for human CMV (standard). Standard dilutions were submitted to nucleic acid extraction with Versant kPCR Molecular systems SP or MagNA Pure LC System followed by the kPCR PLXTM CMV DNA (kPCR) or the CMV R geneTM assay (R-gene), respectively; 139 clinical specimens were tested. Both assays correlated well with the standard (R2 > 0.96) and a matrix effect was observed. Quantitative results correlated reasonably between both assays for whole blood (R2 = 0.79) and well for other specimen types (R2 = 0.93). Quantification differences were within one log10 of the averaged log10 results for 25/27 blood specimens and for 32/33 other specimens. Calibration to the standard did not increase this percentage. In conclusion, results of both assays showed reasonable correlation with each other and good correlation with the standard. Calibration to the standard did not improve comparability of quantitative results. PMID- 29463427 TI - Chronic diarrhea: A case of Waldenstrom macroglobulinemia.

AB - A multidisciplinary working group led by the Swiss Federal Office of Public Health was formed to plan and perform a nationwide survey of patient radiation exposure from computed tomography (CT) in hybrid devices across Nuclear Medicine departments. The survey included 16 departments (of which 5 were university hospitals) and the submitted responses included 10,673 entries for the 33 different protocols proposed (11 in PET and 22 in SPECT). The working group determined the selection and exclusion criteria applied to the analysis. This work presents the survey preparation and data analysis including the exclusion criteria used. The results are used to inform recommendations for National Diagnostic Reference Levels (DRL) for CT procedures in Nuclear Medicine in Switzerland. Of the 33 protocols initially proposed, 10 protocols for both PET and SPECT modalities were retained after exclusion criteria and thresholds were applied. The results obtained in terms of volume-weighted computed tomography dose index (CTDIvol) and dose length product (DLP) have been put forward as recommendations for national Diagnostic Reference Levels for protocols in hybrid imaging devices in Nuclear Medicine in Switzerland and will be published by the Federal Office of Public Health. PMID- 29463429 TI - Molecular epidemiology of tuberculosis. AB - The application of genotyping tools allowed us to discriminate between the Mycobacterium tuberculosis isolates obtained in the laboratory. The differentiation between single strains opened the door to molecular epidemiology studies, which had helped us to progress in our knowledge of how this pathogen is transmitted in the progressively more complex socio-epidemiological scenario. The genetic stability of this microorganism led to develop specific methodologies, which are thoroughly revised in this chapter. In addition to their application in epidemiology, we review, how they can offer a response to different diagnostic and clinical challenges. Finally, we focus on describing the novel genomic revolution we are experiencing in the analysis of tuberculosis, the methodology in which it is based and the novel possibilities it offers, including new routes of integrating both the molecular and genomic languages in innovative post genomic proposals, better suited to our real-life context.

AB - The increasing demand for protein from aquaculture will trigger a global expansion of the sector in coastal and offshore waters. While contributing to food security, potential conflicts with other traditional activities such as fisheries or tourism are inevitable, thus calling for decision-support tools to assess aquaculture planning scenarios in a multi-use context. Here we introduce the AquaSpace tool, one of the first Geographic Information System (GIS)-based planning tools empowering an integrated assessment and mapping of 30 indicators reflecting economic, environmental, inter-sectorial and socio-cultural risks and opportunities for proposed aquaculture systems in a marine environment. A bottom up process consulting more than 350 stakeholders from 10 countries across southern and northern Europe enabled the direct consideration of stakeholder needs when developing the GIS AddIn. The AquaSpace tool is an open source product and builds in the prospective use of open source datasets at a European scale, hence aiming to improve reproducibility and collaboration in aquaculture science and research. Tool outputs comprise detailed reports and graphics allowing key stakeholders such as planners or licensing authorities to evaluate and communicate alternative planning scenarios and to take more informed decisions. With the help of the German North Sea case study we demonstrate here the tool application at multiple spatial scales with different aquaculture systems and under a range of space-related development constraints. The computation of these aquaculture planning scenarios and the assessment of their trade-offs showed that it is entirely possible to identify aquaculture sites, that correspondent to multifarious potential challenges, for instance by a low conflict potential, a low risk of disease spread, a comparable high economic profit and a low impact on touristic attractions. We believe that a transparent visualisation of risks and opportunities of aquaculture planning scenarios helps an effective Marine Spatial Planning (MSP) process, supports the licensing process and simplifies investments.

PMID- 29463434 TI - Molecular Subtypes of Clear-cell Renal Cell Carcinoma are Prognostic for Outcome After Complete Metastasectomy. AB - BACKGROUND: Metastasectomy is routinely performed in selected patients with metastatic clear-cell renal cell carcinoma (ccRCC) as an alternative to systemic therapy. In the absence of randomized trials, the benefit and best way of patient selection remain unclear. Earlier, we described four molecular ccRCC-subtypes (ccrcc1-4) that have a prognostic and predictive value upon first-line sunitinib or pazopanib. OBJECTIVE: Assess the prognostic value of ccrcc1-4 subtypes after complete metastasectomy. (1) Compare outcomes of good-prognosis ccrccc2&3-tumors with intermediate/poor-prognosis ccrcc1&4-tumors. (2) Compare outcomes of the four subtypes separately. DESIGN, SETTING, AND PARTICIPANTS: Single-center retrospective study (1995-2017), assessing 43 ccRCC patients undergoing complete metastasectomy without systemic treatment. INTERVENTION: Molecular subtype determined with established 35-gene expression classifier. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Median disease-free survival (DFS), time to systemic therapy, cancer-specific (CSS) and overall survival (OS) from metastasectomy, estimated with Kaplan-Meier method and tested against other predictors with multivariable Cox regression. RESULTS AND LIMITATIONS: Median DFS was 23 mo for ccrcc2&3-tumors versus 9 mo for ccrcc1&4-tumors (p=0.011, hazard ratio [HR]=2.6). Median time to systemic therapy was 92 mo versus 28 mo (p=0.003, HR=3.3). Median CSS was 133 mo versus 50 mo (p<0.001, HR=2.7). Median OS was 127 mo versus 50 mo (p=0.011, HR=2.5). The classification remained independent upon multivariable analysis. Outcomes remained significantly different when comparing four subtypes separately. The intrinsic heterogeneity of expression profiles is a limitation of this approach. CONCLUSION: Even after clinical patient selection, patients with a ccrcc1- or ccrcc4-tumor are at a higher risk of relapse after complete metastasectomy. Patients with a ccrcc2- or ccrcc3-tumor usually experience a long DFS. These results need validation in a larger cohort to establish the subtypes as prognostic marker. PATIENT SUMMARY: Metastasectomy is recommended for some patients with metastatic clear-cell kidney cancer; however, we do not know who will benefit the most. We show that molecular subtypes increase the possibility to predict which patients are at risk for early relapse after metastasectomy and who may benefit more from other treatment options.

PMID- 29463436 TI - What is the Impact of Smoking on Revision Total Hip Arthroplasty? AB - BACKGROUND: There is a paucity of literature evaluating the impact of smoking on revision total hip arthroplasty (THA) outcomes. The purpose of this study was to identify the effect of smoking on complications after revision THA. METHODS: We queried the American College of Surgeons National Surgical Quality Improvement Program database to identify patients who underwent revision THA between 2006 and 2014. Patients were divided into current smokers and nonsmokers. Each cohort was compared in terms of demographics, preoperative comorbidities, and operative time. Multivariate logistic regression analysis was utilized. Adjusted odds ratios (OR) for the outcomes of any wound complication, deep infection, and reoperation within 30 days of revision THA were calculated. RESULTS: In total, 8237 patients had undergone a revision THA. Of these patients, 14.7% were current smokers and 85.3% were nonsmokers. Univariate analyses demonstrated that smokers had a higher rate of any wound complication (4.1% vs 3.0%, P = .04), deep infection (3.2% vs 1.9%, P = .003), and reoperation (6.8% vs 4.8%, P = .003). Multivariate analysis controlling for confounding demographic, comorbidity, and operative variables identified current smokers as having a significantly increased risk of deep infection (OR, 1.58; 95% CI, 1.04-2.38) and reoperation (OR, 1.37; 95% CI, 1.03-1.85). CONCLUSION: Smoking significantly increases the risk of infection and reoperation after revision THA. The results are even more magnified for revision procedures compared to published effects of smoking on primary THA complications. Further research is needed regarding the impact of smoking cessation on mitigation of these observed risks. PMID- 29463437 TI - Prehospital quick sequential organ failure assessment as a tool to predict in hospital mortality. AB - OBJECTIVE: This study aimed to evaluate the predictive ability of quick sequential organ failure assessment (qSOFA) score for in-hospital mortality among patients transported by physician-staffed helicopters. METHODS: We conducted a single-center, retrospective observational study using the physician-staffed helicopter registry data between 2003 and 2016. We calculated the qSOFA scores based on the patients' vital signs, which were measured on the scene. The tool's discriminatory ability was determined using the area under the curve of the receiver operating characteristic. RESULTS: A total of 1849 patients with a mean age of 63.0 (standard deviation [SD], 18.4) years were included in this study. The diagnostic categories included were trauma and nontrauma cases (1038 [56%] and 811 [44%], respectively). In-hospital mortality was documented in 169 (9%) patients. Meanwhile, the in-hospital mortality rates among patients with qSOFA scores of 0, 1, 2, and 3 were 5/411 (1%), 69/797 (9%), 71/541 (13%), and 24/100 (24%), respectively (P<0.0001 for trend). If the cutoff point is >=1, the sensitivity and specificity of the qSOFA scores were 0.97 and 0.24, respectively. The area under the curve of the qSOFA scores was 0.67 for all patients, whereas that for trauma patients was 0.75. CONCLUSION: An increase in the qSOFA score is associated with a gradual increase in the in-hospital mortality rate among all patients. In particular, a very low mortality rate was observed among patients with a qSOFA score of 0. The qSOFA score predicted the in-hospital mortality of patients with trauma well. PMID- 29463438 TI - Intubation of prehospital patients with curved laryngoscope blade is more successful than with straight blade. AB - OBJECTIVE: Direct laryngoscopy can be performed using curved or straight blades, and providers usually choose the blade they are most comfortable with. However, curved blades are anecdotally thought of as easier to use than straight blades. We seek to compare intubation success rates of paramedics using curved versus straight blades. METHODS: Design: retrospective chart review. SETTING: hospital based suburban ALS service with 20,000 annual calls. SUBJECTS: prehospital patients with any direct laryngoscopy intubation attempt over almost 9years. First attempt and overall success rates were calculated for attempts with curved and straight blades. Differences between the groups were calculated. RESULTS: 2299 patients were intubated by direct laryngoscopy. 1865 had attempts with a curved blade, 367 had attempts with a straight blade, and 67 had attempts with both. Baseline characteristics were similar between groups. First attempt success was 86% with a curved blade and 73% with a straight blade: a difference of 13% (95% CI: 9-17). Overall success was 96% with a curved blade and 81% with a straight blade: a difference of 15% (95% CI: 12-18). There was an average of 1.11 intubation attempts per patient with a curved blade and 1.13 attempts per patient with a straight blade (2% difference, 95% CI: -3-7). CONCLUSIONS: Our study found a significant difference in intubation success rates between laryngoscope blade types. Curved blades had higher first attempt and overall success rates when compared to straight blades. Paramedics should consider selecting a curved blade as their tool of choice to potentially improve intubation success.

AB - INTRODUCTION: Selective serotonin reuptake inhibitors (SSRIs) are a widely used class of drug for various psychiatric disorders during the lifespan, including pregnancy, lactation, childhood, and adolescence. Deterioration in sexual functioning is a major and serious adverse effect of SSRIs. There is emerging evidence that SSRIs can have long-lasting effects on sexuality. AIM: To summarize the long-lasting effects of SSRIs on sexuality, starting with animal models and continuing with the clinical experience of different investigators. METHOD: A literature review of relevant publications in PubMed. MAIN OUTCOME MEASURES: To assess the long-lasting effects of SSRIs on sexuality. RESULTS: Although the persistent effects of SSRIs on sexuality have been little studied in humans, animal studies suggest that SSRIs might cause permanent sexual dysfunction after ending SSRI exposure at a young age but not in adulthood in rats. There are no prospective randomized controlled trials in humans and the present evidence is derived from case reports, incidental research findings, and experiences of some internet communities. CONCLUSION: There is some preclinical evidence from animal studies for enduring SSRI-induced sexual dysfunction, but the available clinical information could prevent a clear decision about the existence of post-SSRI sexual dysfunction, its pathophysiology, and its management. We need more research to fill in the gaps in our knowledge. Coskuner ER, Culha MG, Ozkan B, Kaleagasi EO. Post-SSRI Sexual Dysfunction: Preclinical to Clinical. Is It Fact or Fiction?

AB - BACKGROUND: Ejaculation consists of the emission of semen from seminal vesicles and prostate, followed by expulsion. Ejaculatory dysfunction may take several forms including premature ejaculation, delayed or anejaculation, retrograde ejaculation, and painful ejaculation. Ejaculation is what we can see whereas orgasm is what we feel. The presence of ejaculate does not indicate the ability to experience orgasm. Hence, for the purpose of this work we consider orgasm and ejaculation as 2 separate neurobiological phenomena. AIM: To review the role of advanced investigative techniques such as perineal ultrasound in the diagnosis and management of ejaculation and ejaculatory dysfunction. METHODS: We performed a PubMed search for key words individually and in combination: "ejaculation," "ejaculatory dysfunction," "delayed ejaculation," "painful ejaculation," "retrograde ejaculation," "perineal ultrasound," and "transrectal ultrasound." We also share our local experience using perineal ultrasound in assessing ejaculation. OUTCOMES: Perineal ultrasound can be used as an aid in the investigation of ejaculatory dysfunction. RESULTS: Evaluation of ejaculatory function hinges on a detailed psychosexual history and appropriate physical examination. Function of the ejaculatory center in the spine is androgen dependent; thus, hormonal evaluation is an important aspect of the workup. Disorders of ejaculation and orgasm require evaluation of neuromuscular reflexes activated during sexual activity. Dynamic ultrasonographic (US) ejaculatory orgasmic studies allow for reproducible and detailed descriptions of the sexual response. Transrectal ejaculatory studies are useful in uncovering reasons for lack of antegrade semen emission, especially in men with poor sperm production or after vasectomy. Dynamic US studies contribute clinical utility in its non invasive nature and can provide insight to the dynamic processes surrounding pelvic floor functioning in men. CONCLUSIONS: Perineal US for men with delayed ejaculation or anejaculation, painful ejaculation, or retrograde ejaculation may be helpful in select cases. Further research using this modality may help advance our understanding of ejaculatory dysfunction. Forbes CM, Flannigan R, Paduch DA.

AB - OBJECTIVE: To determine the perception of Primary Care (PC) physicians on the integration with cardiology (CA) through continuity of healthcare programs. MATERIAL AND METHODS: A cross-sectional and multicentre study was conducted, in which a total of 200 PC physicians from all over Spain completed a qualitative survey that evaluated the level of integration with CA in secondary prevention. Physicians were grouped according to the level of PC-CA integration. RESULTS: The integration between CA and PC was good, but it was better in those centres with a higher integration (74.0% vs. 60.0%; p=.02) and in general, physicians considered that integration had improved (92.0% vs. 73.0%; p<.001). Almost all PC physicians received the hospital discharge report. The majority of the hospital discharge reports included recommendations about the CA and PC follow-up, control of risk factors, as well as the duration of secondary prevention treatment, with not significant differences according to the level of integration. In 55.8%, 63.6%, and 51.3% of hospital discharge reports, indications were given on when to perform the follow-up blood analysis, as well as information about returning to working life and sexual activity, respectively. The most common communication method was the paper-based report (75 vs. 84%; p=NS). The communication between healthcare levels was greater in those Primary Care centres with a higher level of integration, as well as periodicity of the communication and the satisfaction of physicians (80.0% vs. 63.0%; p=.005). CONCLUSIONS: The level of integration between PC and CA is, in general, satisfactory, but those centres with a higher level of integration benefit more from a greater communication and satisfaction. PMID- 29463443 TI - BRexit: Possible Brassinosteroid Export and Transport Routes. AB - The movement and differential distribution of endogenous plant hormones are the determining factors for many developmental processes. Brassinosteroids (BRs) are a group of plant steroidal hormones that promote growth and development. Although synthesis and signalling of BRs are well described and characterized, the exit mechanism of these compounds from the cell remains uncharacterizd. Whether BRs are able to move within the apoplast and whether the BR synthesis in one cell can trigger the signalling in its neighbours is also unknown. Here, we draw the attention to these aspects of the BR biology, propose several BR cell export routes and discuss possible consequences of local BR hormonal gradients, resulting from localized biosynthesis and a short-distance transport, for plant development.

AB - Chronic myeloid leukemia (CML), a myeloproliferative neoplasm defined by the t(9;22)(q34;q11) chromosomal translocation, primarily affects older adults. Historically, effective treatment options were not available for older CML patients ineligible for curative allogeneic stem cell transplant, and the disease was therefore usually fatal within several years of diagnosis. The development of tyrosine kinase inhibitors (TKIs) that effectively target the constitutively active mutant tyrosine kinase in CML has dramatically improved outcomes for all patients with CML, including older patients. While older patients were underrepresented in prospective trials, TKI therapy can be successfully administered to older adults with CML with excellent efficacy and proven tolerability. TKI selection and monitoring for adverse events should be tailored based on co-morbidities. As with younger patients, life expectancy of older adults with CML now approaches that of age-matched controls. Here we review guidelines for management of older adults with CML. PMID- 29463447 TI - Novel inhibitors of Staphylococcus aureus RnpA that synergize with mupirocin. AB - We recently discovered RnpA as a promising new drug discovery target for methicillin-resistant S. aureus (MRSA). RnpA is an essential protein that is thought to perform two required cellular processes. As part of the RNA degrasome Rnpa mediates RNA degradation. In combination with rnpB it forms RNase P haloenzymes which are required for tRNA maturation. A high throughput screen identified RNPA2000 as an inhibitor of both RnpA-associated activities that displayed antibacterial activity against clinically relevant strains of S. aureus, including MRSA. Structure-activity studies aimed at improving potency and replacing the potentially metabotoxic furan moiety led to the identification of a number of more potent analogs. Many of these new analogs possessed overt cellular toxicity that precluded their use as antibiotics but two derivatives, including compound 5o, displayed an impressive synergy with mupirocin, an antibiotic used for decolonizing MSRA whose effectiveness has recently been jeopardized by bacterial resistance. Based on our results, compounds like 5o may ultimately find use in resensitizing mupirocin-resistant bacteria to mupirocin. PMID- 29463448 TI - Discovery and validation of 2-styryl substituted benzoxazin-4-ones as a novel scaffold for rhomboid protease inhibitors. AB - Rhomboids are intramembrane serine proteases with diverse physiological functions in organisms ranging from archaea to humans. Crystal structure analysis has provided a detailed understanding of the catalytic mechanism, and rhomboids have been implicated in various disease contexts. Unfortunately, the design of specific rhomboid inhibitors has lagged behind, and previously described small molecule inhibitors displayed insufficient potency and/or selectivity. Using a computer-aided approach, we focused on the discovery of novel scaffolds with reduced liabilities and the possibility for broad structural variations. Docking studies with the E. coli rhomboid GlpG indicated that 2-styryl substituted benzoxazinones might comprise novel rhomboid inhibitors. Protease in vitro assays confirmed activity of 2-styryl substituted benzoxazinones against GlpG but not against the soluble serine protease alpha-chymotrypsin. Furthermore, mass spectrometry analysis demonstrated covalent modification of the catalytic residue Ser201, corroborating the predicted mechanism of inhibition and the formation of an acyl enzyme intermediate. In conclusion, 2-styryl substituted benzoxazinones are a novel rhomboid inhibitor scaffold with ample opportunity for optimization.

AB - Several new glucose-lowering medications have been approved, such as dipeptidyl peptidase-4 inhibitors, glucagon-like peptide-1 receptor agonists (GLP-1RAs), and sodium glucose cotransporter-2 inhibitors. Among GLP-1RAs, lixisenatide, a short acting drug, did not show cardiovascular (CV) benefits in patients with Type 2 diabetes mellitus (T2D) and acute coronary syndrome. Extended-release exenatide was also not significantly better for CV outcomes. By contrast, once daily liraglutide and once weekly semaglutide, both long-acting GLP-1RAs, decreased the incidence of major adverse CV events and mortality. This Review attempts to explain favorable CV results with some, but not all, GLP-1RAs, to aid in their differential prescription with the aim of further reducing the adverse CV burden of T2D. PMID- 29463451 TI - Starvation, Stress Resistance, and Cancer. AB - Cancer cells are characterized by dysregulation in signal transduction and metabolic pathways leading to increased glucose uptake, altered mitochondrial function, and the evasion of antigrowth signals. Fasting and fasting-mimicking diets (FMDs) provide a particularly promising intervention to promote differential effects in normal and malignant cells. These effects are caused in part by the reduction in IGF-1, insulin, and glucose and the increase in IGFBP1 and ketone bodies, which generate conditions that force cancer cells to rely more on metabolites and factors that are limited in the blood, thus resulting in cell death. Here we discuss the cellular and animal experiments demonstrating the differential effects of fasting on normal and cancer cells and the mechanisms responsible for these effects.

AB - OBJECTIVE: To analyze the degree of implementation of the protocolized care for acute stroke in the Spanish emergency departments and to discuss the territorial differences in the treatment of stroke. MATERIAL AND METHODS: Multicenter national survey conducted to evaluate the current treatment of ischemic stroke in emergency departments. The main variables analyzed were focused at evaluating the participation of ERs in the performance of thrombolysis, interventional treatment and destination of patients with stroke. RESULTS: 42 emergency services participated. 90.5% have stroke protocol. In 52.4% is identified an emergency physician referent in cerebrovascular pathology. In 2016 2090 thrombolysis were performed, we observe a great variability in the number of treatments per hospital [0-222]. 11.9% were admitted in the Observation area. Only one-third of the hospitals currently treat stroke with thrombectomy. 31% have a telemedicine service available. CONCLUSIONS: Urgencies plays a fundamental role in the chain of care of stroke treatment. There is a worrying variability between centers in the management of the stroke.

AB - INTRODUCTION: Pharmaceutical care to outpatients is currently one of the main occupations of hospital pharmacy services (PEX). There are several questionnaires to measure the satisfaction of the PEX of a pharmacy service, and the results of these questionnaires can generate improvement actions that result in satisfaction. OBJECTIVES: To verify if a satisfaction questionnaire for outpatients is valid for the generation of improvements in the care provided, and if after its implementation, the same questionnaire is able to detect changes in satisfaction. MATERIAL AND METHOD: Prospective study of a single center carried out in a tertiary hospital in 2015 and 2016. A questionnaire previously validated with 16 Likert-type items was used. Demographic and classification data were collected. A descriptive analysis was performed and the internal consistency was calculated using the Cronbach's alpha value. RESULTS: A total of 258 questionnaires were collected in 2015 and 493 in 2016. There were no differences in the baseline characteristics of the patients and users of the service. The items with the lowest satisfaction scores in 2015 (comfort of the waiting room, dispensing privacy, drug pick-up time and medication pick-up time) guided the improvement actions to be implemented. In 2016 there was an improvement in the waiting time until collection in 12.3% (p = 0.002); in the comfort of the waiting room 4.9% (p = 0.304); business hours for medication collection, 10.7% (p = 0.013); and in the confidentiality of the dispensation 4% (p = 0.292). The remaining scores fluctuated minimally, with no statistical significance at all. A 5.1% improvement in overall satisfaction was found (p < 0.001). Satisfaction values obtained as a whole were high. CONCLUSIONS: The satisfaction questionnaire is a valid instrument for generating actions to improve the care received in an outpatient unit of a pharmacy service. This same questionnaire is a tool to monitor the changes implemented to improve the care received.

AB - BACKGROUND: The differentiation of progressive supranuclear palsy-parkinsonism (PSP-P) from Parkinson's disease (PD) remains a major clinical challenge. OBJECTIVES: To evaluate the diagnostic potential of observer-independent assessments of microstructural integrity within infratentorial brain regions to differentiate PSP-Richardson's syndrome (PSP-RS), PSP-P and PD. METHODS: 3T MRI parameters of mean diffusivity, fractional anisotropy, grey and white matter volumes from patients with PSP-RS (n = 12), PSP-P (n = 12) and mean disease duration of 2.4 +/- 1.7 years were compared with PD patients (n = 20) and healthy controls (n = 23) by using statistical parametric mapping and the spatially unbiased infratentorial template. Subsequently MRI measurements of the dentatorubrothalamic tract were determined observer-independently by a validated probabilistic infratentorial atlas. The impairment of gait and postural stability was evaluated by a sum-score derived from the Unified Parkinson Disease Rating Scale. RESULTS: Significant mean diffusivity increases, fractional anisotropy decreases and corresponding volume loss were localized in mesencephalic tegmentum, superior cerebellar peduncle, decussation of superior cerebellar peduncle and dentate nucleus in PSP-RS and PSP-P compared to PD and healthy controls. Altered microstructural integrity of the dentatorubrothalamic tract in PSP-RS was significantly more pronounced compared to PSP-P and correlated significantly with the gait and postural stability sum-score. Linear discriminant analysis identified diffusion tensor imaging measures of the dentatorubrothalamic tract and the gait and postural stability sum-score to classify correctly 95.5% of PRP-RS, PSP-P and PD patients. CONCLUSIONS: Observer-independent analysis of microstructural integrity within the dentatorubrothalamic tract in combination with assessments of gait and postural stability differentiate PSP-P from PSP-RS and PD in early to moderately advanced stages.

AB - INTRODUCTION: The long-term prognosis of patients with community-acquired pneumonia (CAP) has attracted increasing interest in recent years. The objective of the present study is to investigate the short and long-term outcomes in hospitalized patients with CAP and to identify the predictive factors associated with mortality. PATIENTS AND METHODS: The study was designed as a retrospective, multicenter, observational study. Hospitalized patients with CAP, as recorded in the pneumonia database of the Turkish Thoracic Society between 2011 and 2013, were included. Short-term mortality was defined as 30-day mortality and long-term mortality was assessed from those who survived 30 days. Predictive factors for short- and long-term mortality were analyzed. RESULTS: The study included 785 patients, 68% of whom were male and the mean age was 67+/-16 (18-92). The median duration of follow-up was 61.2+/-11.8 (37-90) months. Thirty-day mortality was 9.2% and the median survival of patients surviving 30 days was 62.8+/-4.4 months. Multivariate analysis revealed that advanced age, the absence of fever, a higher Charlson comorbidity score, higher blood urea nitrogen (BUN)/albumin ratios and lower alanine aminotransferase (ALT) levels were all predictors of long-term mortality. CONCLUSION: Long-term mortality following hospitalization for CAP is high. Charlson score and lack of fever are potential indicators for decreased long-term survival. As novel parameters, baseline BUN/albumin ratios and ALT levels are significantly associated with late mortality. Further interventions and closer monitoring are necessary for such subgroups of patients. PMID- 29463456 TI - Traumatic life event exposure and psychotic-like experiences: A multiple mediation model of cognitive-based mechanisms. AB - Several cognitive mechanisms have been proposed to account for the relationship between exposure to traumatic life events (TLEs) and the entire psychosis spectrum. However, only few of these mechanisms have been empirically tested and those that have been tested have not considered multiple mechanisms simultaneously. The purpose of this study was to examine whether perceived stress, dissociation, negative self-schemas, negative other-schemas, and/or external locus of control mediated the association between TLEs and psychotic like experiences (PLEs). An undergraduate sample of 945 individuals completed a battery of self-report questionnaires. We found significant indirect effects from TLE exposure to PLEs through perceived stress, dissociation, external locus of control, negative self-schemas, and negative other-schemas. When controlling for comorbid psychological symptoms, only the indirect effect from TLE exposure to PLEs through dissociation continued to be significant. Targeting stress sensitivity, maladaptive schemas, dissociative tendencies, and externalizing attributional styles may prove useful in the amelioration of risk for various psychopathologies (e.g., mood, psychosis) in the aftermath of TLE exposure. Findings underscore the importance of targeting trauma-related cognitions in the prevention or reduction of psychotic-like experiences or disorders. PMID- 29463457 TI - Clinical trajectories in the ultra-high risk for psychosis population. AB - BACKGROUND: Traditionally, research in the ultra-high risk (UHR) for psychosis population has focused on the treatment of existing symptomatology and prevention of transition to psychosis. Recently, there has been an increase in focus on outcomes in individuals who do not transition to psychosis. However, there is a lack of standardised definitions of remission, recovery, recurrence and relapse in UHR, resulting in the inability to generalise and replicate outcomes. METHOD: The aims of the current study were to develop definitions for remission, recovery, recurrence and relapse, and apply them to a UHR cohort allowing the identification of longitudinal clinical trajectories. Further stratification in broader categories of favourable and unfavourable outcomes was applied. The predictive value of various baseline factors on specific clinical trajectories was also assessed. RESULTS: 17 different trajectories were identified in a cohort of 202 individuals within a 12-month period and classified according to the suggested definitions for recovery (35.7%), remission (7.5%), any recurrence (20%), no remission (17.3%), relapse (4.0%) and transition to psychosis (15.8%). Favourable and unfavourable trajectories represented 43.2% and 57.1% respectively. Long duration of untreated symptoms and high depression scores were associated with unfavourable outcomes. DISCUSSION: It is possible to apply clear definitions of remission, recovery, recurrence, relapse and transition to psychosis to a UHR cohort to evaluate longitudinal clinical trajectories. Acceptance and use of these definitions will help to facilitate comparisons between trials and to improve clinical clarity across the range of available therapeutic options in UHR individuals.

AB - The aim of this study was to evaluate the results of percutaneous screw fixation of scaphoid waist fractures in our surgery unit by comparing them with recent data from the literature. This was a retrospective, descriptive study conducted between January 2010 and September 2016. Patients operated due to a recent scaphoid fracture and treated by percutaneous anterograde screw fixation with a Herbert screw were included in this study. Our cohort was a sub-set from a scaphoid fracture group; other fracture sites, other treatment techniques and fractures associated with scapholunate ligament lesions were excluded. The time to union and union rate were recorded. The Youm and McMurtry indices, scaphoid and scapholunate angles were measured on radiographs. A total of 21 patients were included. The mean age was 30 years (18-44) and the sex ratio (male/female) was 9.5. The union rate was 95% with an average follow-up of 24 months. Four patients had a mobility deficit in the sagittal plane of about 9 degrees . No malunion was found, and no major complications were observed. Based on this study, percutaneous fixation of the scaphoid with Herbert's screw is a reliable technique that leads to union in most cases with limited postoperative immobilization. PMID- 29463459 TI - Intraoperative cone beam computed tomography-guided endovascular recanalization of an interrupted aorta. AB - A 42-year-old man sustained a stroke secondary to malignant hypertension and was found to have complete aortic interruption. We report a case of real-time image guided endovascular repair to highlight the value of preprocedural planning and intraprocedural cone beam computed tomography. Two-dimensional fluoroscopy enhanced with three-dimensional landmarks from cone beam computed tomography was used to direct a Nykanen radiofrequency wire (Baylis Medical, Montreal, Quebec, Canada) through the interruption, avoiding critical adjacent structures. A covered Cheatham-Platinum stent (NuMED, Inc, Hopkinton, NY) was deployed successfully, recanalizing the thoracic aorta. The pressure gradient normalized, and the patient was discharged on postoperative day 1. At 10-month follow-up, the patient was on an antihypertensive regimen of two minimum-dose drugs.

PMID- 29463461 TI - Aromatherapy Versus Oral Ondansetron for Antiemetic Therapy Among Adult Emergency Department Patients: A Randomized Controlled Trial. AB - STUDY OBJECTIVE: We compare aromatherapy with inhaled isopropyl alcohol versus oral ondansetron for treating nausea among emergency department (ED) patients not requiring immediate intravenous access. METHODS: In a randomized, blinded, placebo-controlled trial, we enrolled a convenience sample of adults presenting to an urban tertiary care ED with chief complaints including nausea or vomiting. We randomized subjects to 1 of 3 arms: inhaled isopropyl alcohol and 4 mg oral ondansetron, inhaled isopropyl alcohol and oral placebo, and inhaled saline solution placebo and 4 mg oral ondansetron. The primary outcome was mean nausea reduction measured by a 0- to 100-mm visual analog scale from enrollment to 30 minutes postintervention. Secondary outcomes included receipt of rescue antiemetic medications and adverse events. RESULTS: We enrolled 122 subjects, of whom 120 (98.3%) completed the study. Of randomized subjects, 40 received inhaled isopropyl alcohol and oral ondansetron, 41 received inhaled isopropyl alcohol and oral placebo, and 41 received inhaled saline solution placebo and oral ondansetron. The mean decrease in nausea visual analog scale score in each arm was 30 mm (95% confidence interval [CI] 22 to 37 mm), 32 mm (95% CI 25 to 39 mm), and 9 mm (95% CI 5 to 14 mm), respectively. The proportions of subjects who received rescue antiemetic therapy in each arm were 27.5% (95% CI 14.6% to 43.9%), 25.0% (95% CI 12.7% to 41.2%), and 45.0% (95% CI 29.3% to 61.5%), respectively. There were no adverse events. CONCLUSION: Among ED patients with acute nausea and not requiring immediate intravenous access, aromatherapy with or without oral ondansetron provides greater nausea relief than oral ondansetron alone. PMID- 29463462 TI - Vasoactive Inotropic Score as a Predictor of Mortality in Adult Patients With Cardiogenic Shock: Medical Therapy Versus ECMO. AB - INTRODUCTION AND OBJECTIVES: This study investigated whether the vasoactive inotropic score (VIS) is independently predictive of mortality in cardiogenic shock (CS). METHODS: This study was retrospective, observational study. Patients who were admitted to the cardiac intensive care unit from January 2012 to December 2015 were screened, and 493 CS patients were finally enrolled. To quantify pharmacologic support, the patients were divided into 5 groups based on a quintile of VIS: 1 to 10, 11 to 20, 21 to 38, 39 to 85, and > 85. The primary outcome was in-hospital mortality. RESULTS: In-hospital mortalities in the 5 VIS groups in increasing order were 8.2%, 14.1%, 21.1%, 32.0%, and 65.7%, respectively (P < .001). Multivariable analysis indicated that VIS ranges of 39 to 85 (aOR, 3.85; 95%CI, 1.60-9.22; P = .003) and over 85 (aOR, 10.83; 95%CI, 4.43-26.43; P < .001) remained significant prognostic predictors for in-hospital mortality. With multiple logistic regression to remove any confounding effects, we found that the localized regression lines regarding the odds of death intersected each other's (medical therapy alone and combined extracorporeal membrane oxygenation group) path at VIS = 130. In contrast to linear correlation between VIS and mortality for patients treated with medical therapy alone, there was little association between a VIS of 130 or more and the probability of in hospital mortality for patients who were treated with extracorporeal membrane oxygenation. CONCLUSIONS: A high level of vasoactive inotropic support during the first 48hours was significantly associated with increased in-hospital mortality in adult CS patients. PMID- 29463463 TI - Effect of primary admission to burn centers on the outcomes of severely burned patients. AB - OBJECTIVE: Burns represent a special form of severe trauma. Due to long hospitalization, rehabilitation, and extensive scar treatment, severe burn injuries rank among the most expensive traumatic injuries regarding associated health care costs. The presented single-burn-center experiences evaluated the effects of primary versus secondary burn intensive care unit (BICU) admissions on outcomes in severely burned patients. METHODS: Within 30 months, 186 patients were admitted to the BICU. The cases were divided into two groups depending on their admission type: "primary" vs. "secondary". All patients were analyzed retrospectively regarding the need for surgery, encountered complications, time of hospitalization and overall survival. RESULTS: The incidence of primary BICU admissions was 65.1%. Both patient groups were comparable regarding demographics, comorbidities, % TBSA burn, associated inhalation injuries, ABSI scores and intubation rates (p>0.05). Both groups received similar numbers of operations and had overall comparable mortality rates (p>0.05). However, duration until first burn excision, length of ventilation, as well as BICU- and overall hospital length of stay were significantly shorter in the "primary"- compared to the "secondary" group (p<0.05). CONCLUSION: Several burn societies have published precise criteria of when a patient needs to be referred to a burn center. In the presented series, patients that were primarily treated at a BICU showed significantly better outcomes regarding several parameters. In order to further optimize treatment of burn patients it therefore appears that precise initial assessment and if appropriate respective primary transport to dedicated burn centers needs to be re-emphasized, especially among first- and emergency care providers. PMID- 29463464 TI - Epididymal sperm from Spix's yellow-toothed cavies sperm successfully cryopreserved in Tris extender with 6% glycerol and 20% egg yolk. AB - As a non-threatened hystricognath rodent species, Spix's yellow-toothed cavies can be used as a model for the development of assisted reproductive techniques for the conservation of closely related species. The objective was to establish a functional protocol for cryopreservation of epididymal sperm from these cavies. Twelve sexually mature males, ~2 y old and weighing ~300 g, were euthanized. Sperm were recovered by retrograde flushing of the vas deferens and cauda epididymis with Tris extender. Thereafter, sperm were extended in Tris plus 20% egg yolk, with 3%, 6% or 9% glycerol or dimethyl sulfoxide (DMSO), placed in 0.25 mL straws and cryopreserved in liquid nitrogen. Sperm concentration, motility (using computer-assisted sperm analysis; CASA), plasma membrane integrity, osmotic response, morphology and sperm binding-ability were determined in fresh and frozen-thawed sperm. For most sperm endpoints, glycerol was a more desirable cryoprotectant than DMSO. Data (mean +/- SEM) were similar with use of 3%, 6%, and 9% glycerol (P > 0.05) in osmotic response (40.66 +/- 6.3%, 42.5 +/- 7.1%, and 39.5 +/- 5.0% respectably), and membrane integrity (55.17 +/- 5.5%, 68.4 +/- 4.1%, and 59.1 +/- 4.9% respectably). Among concentrations assessed, the use of 6% glycerol resulted in the greatest (P < 0.05) post-thaw values for total motility (60.9 +/- 4.4%), rapid subpopulation motility (27.7 +/- 3.1%) and sperm binding capability (227.0 +/- 20.2). In conclusion, epididymal sperm from the Spix's yellow-toothed cavies (G. spixii) are optimally cryopreserved in Tris extender with 6% glycerol and 20% egg yolk. PMID- 29463465 TI - Secondary pulmonary syphilis: Case report and review of literature. AB - INTRODUCTION: Syphilis is a sexually transmitted disease that can affect numerous organs in its secondary or tertiary stages. We describe a case of secondary syphilis with pulmonary involvement and we present a literature review. PATIENTS AND METHODS: A 69-year-old male patient was admitted to hospital for dyspnoea and extended papular exanthema with palmoplantar involvement. The serological test for syphilis was positive. Ocular examination showed bilateral papillitis and retinal haemorrhage. Chest radiography revealed an interstitial alveolar infiltrate predominantly in the upper lobes, mild pleural effusion and hilar adenopathy. These infiltrates were slightly hypermetabolic on PET scan suggesting inflammatory or infectious origin. Treatment with intravenous penicillin G was effective on cutaneous, ocular and pulmonary manifestations. DISCUSSION: Lung involvement in secondary syphilis is poorly known and rarely described. We found 27 cases of pulmonary syphilis reported in English and the main European languages since 1967. Mean age at diagnosis was 46 years with clear male predominance (89%). HIV co-infection was declared in 5 cases. Treponema pallidum was found in 6 patients using PCR on bronchoalveolar lavage (BAL) (3 patients) or on a lung biopsy (1 patient), immunohistochemistry (IHC) on BAL (1 patient) and Giemsa staining on a pleural fluid sample (1 patient). Chest X-rays may show unilateral or bilateral infiltrates or nodules with or without pleural effusion or hilar adenopathy. Sub-pleural involvement is frequent and penicillin is the treatment of choice. CONCLUSION: Pulmonary syphilitic involvement should be suspected where pulmonary symptoms or radiological changes occur in secondary syphilis. IHC, special staining or PCR on BAL, pleural fluid or lung tissue are useful for the identification of spirochetes. PMID- 29463466 TI - Right ventricular dysfunction in congenitally corrected transposition of the great arteries and risk of ventricular tachyarrhythmia and sudden death. AB - BACKGROUND: It is unknown whether systemic right ventricular (SRV) dysfunction confers increased risk for sudden death in congenitally corrected transposition of the great arteries (ccTGA). We sought to define risk of ventricular arrhythmias and sudden death attributable to systemic right ventricular dysfunction in ccTGA. METHODS: The study cohort is comprised of adult patients with a diagnosis of ccTGA. Clinical information and clinical outcomes including ICD therapy, incidence of VT/VF, and cause of death were reviewed. RESULTS: 129 patients with ccTGA were followed for 7.2 +/- 3.4 years. Mean SRV ejection fraction (SRVEF) was 39% (n = 56 with an EF <35%). Significant documented arrhythmia (sustained VT requiring defibrillation or cardiac arrest due to VT/VF) occurred in 13/56 patients (23%) with SRV EF <35% compared with 2/73 (3%) with SRV EF >35% (p < 0.001). There was no significant difference in age at death, death from documented arrhythmia, or death from all cause between patients with SRV EF <35% and >35%. However, risk of sudden death was higher in patients with SRV EF <35% (16% vs 1%, p = 0.002). The combined clinical endpoint of ICD therapy, clinically significant VT/VF, and sudden death was significantly higher in patients with SRV EF <35% than in patients with SRV EF >35%, independent of the presence of LV EF <35% (p < 0.001). CONCLUSIONS: Dysfunction of the systemic RV in ccTGA increases the risk of sudden death and clinically significant ventricular tachyarrhythmias. Further study is needed to determine if ventricular tachyarrhythmias comprise the primary cause of sudden death in these patients and if ICDs offer any significant mortality benefit.

AB - Protein kinases regulate every aspect of cellular activity, whereas metabolic enzymes are responsible for energy production and catabolic and anabolic processes. Emerging evidence demonstrates that some metabolic enzymes, such as pyruvate kinase M2 (PKM2), phosphoglycerate kinase 1 (PGK1), ketohexokinase (KHK) isoform A (KHK-A), hexokinase (HK), and nucleoside diphosphate kinase 1 and 2 (NME1/2), that phosphorylate soluble metabolites can also function as protein kinases and phosphorylate a variety of protein substrates to regulate the Warburg effect, gene expression, cell cycle progression and proliferation, apoptosis, autophagy, exosome secretion, T cell activation, iron transport, ion channel opening, and many other fundamental cellular functions. The elevated protein kinase functions of these moonlighting metabolic enzymes in tumor development make them promising therapeutic targets for cancer. PMID- 29463473 TI - Poorly Controlled Homocystinuria: A Rare Cause of Ischemic Priapism? AB - We report on the 1st case of ischemic priapism secondary to poorly controlled homocystinuria. Homocystinuria is a rare, autosomal recessive, inherited disorder of metabolism that is caused by a deficiency of cystathionine synthase, leading to marked hyperhomocysteinemia. Arterial and/or venous thromboemboli are a major cause of mortality and morbidity in patients with homocystinuria. Untreated patients have a 50% chance of having a vascular event by 30 years of age. Increased homocysteine levels have been reported to upregulate prothrombotic factors and downregulate antithrombotic factors; in particular, increased homocystinuria has been found to downregulate nitric oxide (NO). Mice that are deficient in NO synthase in the cavernosal smooth muscles have a higher incidence of priapism. Decrease in NO synthase causes downregulation of cyclic guanosine monophosphate, phosphodiesterase type 5A, and Rho A/Rho-kinase. Because persistently increased homocysteine also downregulates NO, a similar mechanism could be proposed for priapism secondary to homocystinuria. In patients presenting with priapism, specific features of homocystinuria should be sought; in selected patients, screening with plasma total homocysteine might be appropriate. Ischemic priapism secondary to homocystinuria appears to respond well to the standard treatment options of aspiration, intracavernosal injection with phenylephrine, and, if required, a shunting procedure.

PMID- 29463471 TI - IL-4 Receptor Alpha Signaling through Macrophages Differentially Regulates Liver Fibrosis Progression and Reversal. AB - : Chronic hepatitis leads to liver fibrosis and cirrhosis. Cirrhosis is a major cause of worldwide morbidity and mortality. Macrophages play a key role in fibrosis progression and reversal. However, the signals that determine fibrogenic vs fibrolytic macrophage function remain ill defined. We studied the role of interleukin-4 receptor alpha (IL-4Ralpha), a potential central switch of macrophage polarization, in liver fibrosis progression and reversal. We demonstrate that inflammatory monocyte infiltration and liver fibrogenesis were suppressed in general IL-4Ralpha-/- as well as in macrophage-specific IL-4Ralpha /- (IL-4RalphaDeltaLysM) mice. However, with deletion of IL-4RalphaDeltaLysM spontaneous fibrosis reversal was retarded. Results were replicated by pharmacological intervention using IL-4Ralpha-specific antisense oligonucleotides. Retarded resolution was linked to the loss of M2-type resident macrophages, which secreted MMP-12 through IL-4 and IL-13-mediated phospho-STAT6 activation. We conclude that IL-4Ralpha signaling regulates macrophage functional polarization in a context-dependent manner. Pharmacological targeting of macrophage polarization therefore requires disease stage-specific treatment strategies. RESEARCH IN CONTEXT: Alternative (M2-type) macrophage activation through IL-4Ralpha promotes liver inflammation and fibrosis progression but speeds up fibrosis reversal. This demonstrates context dependent, opposing roles of M2-type macrophages. During reversal IL-4Ralpha induces fibrolytic MMPs, especially MMP-12, through STAT6. Liver-specific antisense oligonucleotides efficiently block IL-4Ralpha expression and attenuate fibrosis progression. PMID- 29463472 TI - Interferon Gamma Induces Reversible Metabolic Reprogramming of M1 Macrophages to Sustain Cell Viability and Pro-Inflammatory Activity. AB - Classical activation of M1 macrophages with lipopolysaccharide (LPS) is associated with a metabolic switch from oxidative phosphorylation to glycolysis. However, the generalizability of such metabolic remodeling to other modes of M1 macrophage stimulation, e.g. type II interferons (IFNs) such as IFNgamma, has remained unknown as has the functional significance of aerobic glycolysis during macrophage activation. Here we demonstrate that IFNgamma induces a rapid activation of aerobic glycolysis followed by a reduction in oxidative phosphorylation in M1 macrophages. Elevated glycolytic flux sustains cell viability and inflammatory activity, while limiting reliance on mitochondrial oxidative metabolism. Adenosine triphosphate (ATP) distributed by aerobic glycolysis is critical for sustaining IFN-gamma triggered JAK (Janus tyrosine kinase)-STAT-1 (Signal Transducer and Activator of Transcription 1) signaling with phosphorylation of the transcription factor STAT-1 as its signature trait. Inhibition of aerobic glycolysis not only blocks the M1 phenotype and pro inflammatory cytokine/chemokine production in murine macrophages and also human monocytes/macrophages. These findings extend on the potential functional role of immuno-metabolism from LPS- to IFNgamma-linked diseases such as atherosclerosis and autoimmune disease. PMID- 29463474 TI - Sexual Self-Schema Scale for Women-Validation and Psychometric Properties of the Polish Version. AB - INTRODUCTION: The sexual self-schema is a part of a broader concept of the self that is believed to be crucial for intrapersonal and interpersonal sexual relationships. AIM: To develop and perform psychometric validation of the Polish version of the Sexual Self-Schema Scale for Women (SSSS-W-PL). METHODS: 561 women 18 to 55 years old were included in the final analysis. Linguistic validation was performed in 4 steps in line with the MAPI Institute guidelines. Convergent validity was calculated using the Pearson r product-moment coefficient between different measures of sexuality (attitudes and experience, behavior, arousal, romantic relationship) and SSSS-W-PL total and factor scores. To test discriminant validity, we applied hierarchical regression analyses predicting the number of lifetime sexual partners, self-rating as a sexual person (1 item, "I feel sexually attractive"; on a 5-point Likert scale), and arousability, with independent variables being extraversion (Ten-Item Personality Inventory), self esteem (Rosenberg Self-Esteem Scale), and the SSSS-W-PL (total and factor scores). MAIN OUTCOMES MEASURES: Sexual self-schema was measured by the SSSS-W PL, whereas arousability was measured by the arousal/excitement scale of the Changes in Sexual Functioning Questionnaire. RESULTS: The mean age of the study population was 29.0 +/- 7.6 years. The final scale consisted of 24 adjectives grouped within 4 factors: romantic, passionate, direct, and embarrassed. The 4 factor model accounted for 39% of the variance. The Cronbach alpha was 0.74 for the SSSS-W-PL total score and 0.61 to 0.84 for individual factors. Test-retest reliability of the scale after 2- to 8-week intervals was 0.87 (95% CI = 0.82 0.86, P < .001). The increment variances were statistically significant and ranged from 3.8% to 11.6%. CONCLUSION: The analysis showed good psychometric properties and internal validity of the SSSS-W-PL. The SSSS-W-PL might be helpful in consulting and/or providing sexual therapy to gynecologic cancer survivors or women with a history of childhood sexual abuse.

PMID- 29463475 TI - Preliminary Validation of a German Version of the Sexual Complaints Screener for Women in a Female Population Sample. AB - BACKGROUND: To date, neither the original English nor any of the translated versions of the Sexual Complaints Screener for Women (SCS-W) have been tested for their psychometric properties. AIM: To evaluate the validity and utility of the German version of the SCS-W by assessing content, convergent, and discriminant validity. METHODS: A population sample of 309 women (mean age = 26.9 years) completed the online survey and had matching data available on the SCS-W and the Female Sexual Function Index (FSFI). Spearman bivariate correlations between the SCS-W and FSFI domain scores and exploratory factor analysis with principal component analysis were conducted. OUTCOMES: Convergent validity was excellent for the domain of orgasm, good for satisfaction, dyspareunia, and the total questionnaire score, and acceptable for desire, lubrication, arousal, and vaginismus. Discriminant validity was present for all domains apart from arousal, lubrication, and vaginismus. Varimax rotation suggested an 8-factor model was the most robust. CLINICAL IMPLICATIONS: This brief screener seems suitable to provide a brief overview of female patients' sexual problems in a clinical setting. STRENGTHS AND LIMITATIONS: This is the 1st study to assess the psychometric properties of the German version of the SCS-W. However, available information on the psychometric properties of the German SCS-W was limited because the validity of the screener could not be counterchecked against a clinical diagnosis of female sexual dysfunction. CONCLUSION: Our results provide preliminary evidence of good validity of the German version of the SCS-W. Overall, the SCS-W can offer support for clinicians who are less familiar with sexual medicine and who might not routinely discuss sexual issues with their patients. Burri A, Porst H.

Infibulation is responsible for significant urogynecological, obstetrical, and psychosexual consequences that can be treated with defibulation (or de-infibulation), an operation that opens the infibulation scar, exposing the vulvar vestibule, vaginal orifice, external urethral meatus, and eventually the clitoris.

AIM: To study the current prevalence of gender dysphoria, how frequently gender-affirming treatments are performed, and the number of people experiencing regret of this treatment. METHODS: The medical files of all people who attended our gender identity clinic from 1972 to 2015 were reviewed retrospectively. OUTCOMES: The number of (and change in) people who applied for transgender health care, the percentage of people starting with gender-affirming hormonal treatment (HT), the estimated prevalence of transgender people receiving gender-affirming treatment, the percentage of people who underwent gonadectomy, and the percentage of people who regretted gonadectomy, specified separately for each year. RESULTS: 6,793 people (4,432 birth-assigned male, 2,361 birth-assigned female) visited our gender identity clinic from 1972 through 2015. The number of people assessed per year increased 20-fold from 34 in 1980 to 686 in 2015. The estimated prevalence in the Netherlands in 2015 was 1:3,800 for men (transwomen) and 1:5,200 for women (transmen). The percentage of people who started HT within 5 years after the 1st visit decreased over time, with almost 90% in 1980 to 65% in 2010. The percentage of people who underwent gonadectomy within 5 years after starting HT remained stable over time (74.7% of transwomen and 83.8% of transmen). Only 0.6% of transwomen and 0.3% of transmen who underwent gonadectomy were identified as experiencing regret. CLINICAL IMPLICATIONS: Because the transgender population is growing, a larger availability of transgender health care is needed. Other health care providers should familiarize themselves with transgender health care, because HT can influence diseases and interact with medication. Because not all people apply for the classic treatment approach, special attention should be given to those who choose less common forms of treatment. STRENGTHS AND LIMITATIONS: This study was performed in the largest Dutch gender identity clinic, which treats more than 95% of the transgender population in the Netherlands. Because of the retrospective design, some data could be missing. CONCLUSION: The number of people with gender identity issues seeking professional help increased dramatically in recent decades. The percentage of people who regretted gonadectomy remained small and did not show a tendency to increase. Wiepjes CM, Nota NM, de Blok CJM, et al.

PMID- 29463478 TI - Association Between Gender Confirmation Treatments and Perceived Gender Congruence, Body Image Satisfaction, and Mental Health in a Cohort of Transgender Individuals. AB - BACKGROUND: Transgender individuals sometimes seek gender confirmation treatments (GCT), including hormone therapy (HT) and/or surgical change of the chest and genitalia ("top" and "bottom" gender confirmation surgeries). These treatments may ameliorate distress resulting from the incongruence between one's physical appearance and gender identity. AIM: The aim was to examine the degree to which individuals' body-gender congruence, body image satisfaction, depression, and anxiety differed by GCT groups in cohorts of transmasculine (TM) and transfeminine (TF) individuals. METHODS: The Study of Transition, Outcomes, and Gender is a cohort study of transgender individuals recruited from 3 health plans located in Georgia, Northern California, and Southern California; cohort members were recruited to complete a survey between 2015-2017. Participants were asked about: history of GCT; body-gender congruence; body image satisfaction; depression; and anxiety. Participants were categorized as having received: (1) no GCT to date; (2) HT only; (3) top surgery; (4) partial bottom surgery; and (5) definitive bottom surgery. OUTCOMES: Outcomes of interest included body-gender congruence, body image satisfaction, depression, and anxiety. RESULTS: Of the 2,136 individuals invited to participate, 697 subjects (33%) completed the survey, including 347 TM and 350 TF individuals. The proportion of participants with low body-gender congruence scores was significantly higher in the "no treatment" group (prevalence ratio [PR] = 3.96, 95% CI 2.72-5.75) compared to the definitive bottom surgery group. The PR for depression comparing participants who reported no treatment relative to those who had definitive surgery was 1.94 (95% CI 1.42-2.66); the corresponding PR for anxiety was 4.33 (95% CI 1.83-10.54). CLINICAL TRANSLATION: Withholding or delaying GCT until depression or anxiety have been treated may not be the optimal treatment course given the benefits of reduced levels of distress after undergoing these interventions. CONCLUSIONS: Strengths include the well-defined sampling frame, which allowed correcting for non-response, a sample with approximately equal numbers of TF and TM participants, and the ability to combine data on HT and gender confirmation surgeries. Limitations include the cross-sectional design and the fact that participants may not be representative of the transgender population in the United States. Body-gender congruence and body image satisfaction were higher, and depression and anxiety were lower among individuals who had more extensive GCT compared to those who received less treatment or no treatment at all.

PMID- 29463479 TI - The Moderating Role of Leader-Member Exchange in the Relationships Between Emotional Labor and Burnout in Clinical Nurses. AB - PURPOSE: This study aimed to identify the moderating effect of leader-member exchange in the relationship between emotional labor and burnout among clinical nurses. METHODS: A cross-sectional study design was used. Participants were 170 registered nurses working in the general wards of two tertiary hospitals in Seoul, South Korea. The data were collected through convenience sampling using self-report measures of emotional labor, leader-member exchange, and burnout. The data were analyzed using hierarchical multiple regression. RESULTS: Data from 165 nurses (response rate 97.1%) were utilized. The mean age of the participants was 28.42 years (SD = 5.43), and their mean years of experience as a nurse was 5.80 years (SD = 5.51). First, emotional modulation efforts in their profession and patient-focused emotional suppression (both factors of emotional labor) showed significant negative and positive effects, respectively, on burnout. Second, leader-member exchange showed a significant negative effect on burnout. Finally, when controlling for marital status and work unit, leader-member exchange had a moderating effect on the relationship between burnout and the two aforementioned factors of emotional labor. CONCLUSION: The results of this study suggest that as a way to reduce burnout, institutional support to enhance leader-member exchange should be established for nurses who are experiencing emotional labor. PMID- 29463480 TI - Prevalence and Influencing Factors of Metabolic Syndrome Among Persons with Physical Disabilities. AB - PURPOSE: Metabolic syndrome is an important cluster of coronary heart disease risk factors. However, it remains unclear to what extent metabolic syndrome is associated with demographic and potentially modifiable lifestyle factors among Korean persons with physical disabilities. This study aimed to determine the prevalence and influencing factors of metabolic syndrome among persons with physical disabilities using the Korean National Health Insurance Service-National Sample Cohort. METHODS: The Adult Treatment Panel III criteria were used to define metabolic syndrome influencing factors and prevalence, which were evaluated in a representative sample from the 2013 Korean National Health Insurance Service-National Sample Cohort database. Characteristics were compared based on frequency using the chi2 test. The associations between metabolic syndrome and its risk factors were estimated using logistic multivariable regression analysis. RESULTS: Metabolic syndrome was detected in 31.5% of the surveyed persons with physical disabilities. Female sex, age of >=65 years, smoking, greater alcohol consumption, physical inactivity, higher body mass index, and a family history of diabetes were associated with increased risks of metabolic syndrome. CONCLUSION: The major risk factors for metabolic syndrome among persons with physical disabilities were obesity and older age. Performing physical activity was associated with a lower risk of metabolic syndrome. Therefore, we recommend using a continuous obesity management program and physical activity to prevent metabolic syndrome among persons with physical disabilities. PMID- 29463481 TI - Influencing Factors and Consequences of Workplace Bullying among Nurses: A Structural Equation Modeling. AB - PURPOSE: The purpose of this study was to build and test a model outlining the factors related to workplace bullying among nurses. The hypothesized model included authentic leadership and a relationship-oriented organizational culture as influencing factors, symptom experience and turnover intention as consequences, and positive psychological capital as a mediator of workplace bullying among nurses. METHODS: We obtained structured questionnaire data from 301 nurses working at hospitals in South Korea. Based on these data, the developed model was verified via a structural equation modeling analysis using SPSS and AMOS program. RESULTS: The fit indices of the hypothesized model satisfied recommended levels; chi2 = 397.58 (p < .001), normed chi2 (chi2/df) = 1.82, RMR = .05, TLI = .93, CFI = .94, RMSEA = .05. A relationship-oriented organizational culture had a direct effect on workplace bullying (beta = -.48, p < .001). Furthermore, workplace bullying had a direct effect on symptom experience (beta = .36, p < .001), and this relationship was mediated by positive psychological capital (beta = .15, p = .003). Workplace bullying also had an indirect effect on turnover intention (beta = .20, p = .007). Finally, symptom experience had a direct effect on turnover intention (beta = .31, p = .002). CONCLUSION: These results suggest that workplace bullying among nurses may be prevented by constructing a relationship-oriented organizational culture, as long as employees have sufficient positive psychological capital. In this regard, workplace bullying among nurses should be addressed using a comprehensive strategy that considers both individual and organizational factors. PMID- 29463482 TI - Contributions and Limitations of National Cervical Cancer Screening Program in Korea: A Retrospective Observational Study. AB - PURPOSE: The purpose of this study was to evaluate the contributions and limitations of the cervical cancer screening test with accuracy in Korea. METHODS: This was a retrospective observational study. The study population consisted of all participants who underwent cervical cancer screening test from 2009 to 2014. The data were obtained from National Health Information Database (NHID) which represents medical use records of most Koreans. As the indices for contributions and limitations of the screening test, crude detection rate, incidence rate of interval cancer, sensitivity, specificity, and positive predictive value were used. RESULTS: The crude detection rate of screening test per 100,000 participants increased from 100.7 in 2009 to 102.1 in 2014. The incidence rate of interval cancer per 100,000 negatives decreased from 13.0 in 2009 to 10.2 in 2014. The sensitivities of screening test were 88.7% in 2009 and 91.2% in 2014, and the specificities were 98.5% in 2009 and 97.7% in 2014. The positive predictive value of screening decreased from 6.2% in 2009 to 4.3% in 2014. CONCLUSION: The Korean national cervical cancer screening program has improved in accuracy and has contributed to detection of early stage of cervical cancer over the years. Along with efforts to promote participation in cancer screening programs, quality control over the screening program should be enhanced. PMID- 29463483 TI - The Experience of Paid Family-Care Workers of People with Dementia in South Korea. AB - PURPOSE: The South Korean government introduced the universal long-term care insurance program in 2008 that created a new employment category of "paid family care worker" to assist the elderly with chronic illnesses including dementia. The aim of this study was to understand the lived experience of paid family-care workers of people with dementia in South Korea. METHODS: The study was a qualitative research design underpinned by interpretive description principles involving eight paid family-care workers. The participants were recruited by attaching the advertisement flyer in a notice board of an educational facility for paid family-care workers. RESULTS: Paid family-care workers struggled to manage the behavioral and psychological symptoms of their care recipients. Their workloads created physical, emotional, social, and financial burdens. However, the care-giving activities were encouraged through their sense of responsibility, filial piety, and personal religious beliefs. Financial subsidies from the government and help received from others were also identified as encouragements. The education course provided to them assisted them to improve their dementia care capabilities. CONCLUSION: Understanding paid family-care workers' lived experience in dementia care in South Korea assists with the identification of their educational needs and level of support they require to improve dementia care in the home care environment. A number of suggestions are made to increase paid family-care workers' knowledge, clinical skills, and job satisfaction to reduce their burdens and work-related incidents, such as challenging behaviors from those being cared for. PMID- 29463484 TI - The Effects of an Interactive Nursing Skills Mobile Application on Nursing Students' Knowledge, Self-efficacy, and Skills Performance: A Randomized Controlled Trial. AB - PURPOSE: Clinical nursing practice is important because it helps nursing students experience realities of clinical nursing that cannot be learned through theoretical education. This study aimed to evaluate the effect of an interactive nursing skills mobile application for nursing students. METHODS: Sixty-six senior nursing students were randomly assigned to experimental or control groups. The experimental group used an interactive nursing skills mobile application for 1 week. The control group was provided with a mobile application containing noninteractive nursing video contents for 1 week. Before (pre-test) and 1 week after (post-test) using the mobile application, participants' knowledge of clinical nursing skills, self-efficacy of nursing practice, and nursing skills performance were assessed. RESULTS: The experimental group showed a significantly higher value for knowledge after 1 week of treatment via their mobile application than the control group (t = 3.34, p = .001). In addition, they showed significantly improved self-efficacy before and after intervention (t = 2.46, p = .017) than the control group. The experimental group's nursing skills performance was also significantly enhanced after intervention (t = 7.05, p < .001), with a significant difference in the degree of improvement (t = 4.47, p < .001). CONCLUSION: The interactive learner-centered nursing education mobile application with systematic contents was an effective method for students to experience practical nursing skills. Developing and applying a mobile application with other nursing contents that can be effectively used across all range of nursing students is recommended. PMID- 29463485 TI - Effect of Structured Bed Exercise on Uterine Contractions, Fetal Heart Rate Patterns, and Maternal Psychophysical Symptoms of Hospitalized High-Risk Pregnant Women: A Randomized Control Trial. AB - PURPOSE: This study examined the effect on uterine contraction frequency (UCF), blood pressure (BP), heart rate (HR), fetal heart rate (FHR) patterns and psychophysical symptoms (physical discomfort, anxiety, and depression) of structured bed exercise (SBE) in hospitalized high-risk pregnant women prescribed bed rest. METHODS: Forty-five hospitalized high risk pregnant women at >24 weeks of pregnancy prescribed bed rest were randomly assigned to the experimental or control group. From January to May 2014, data were collected using electronic fetal monitoring and patient monitoring of UCF, BP, HR and FHR patterns, and psychophysical symptoms were measured using the antenatal physical discomfort scale, state-trait anxiety scale, and Edinburgh postnatal depression scale. RESULTS: UCF, BP, HR, and FHR patterns (rate, variability, acceleration, and deceleration) did not differ significantly between the experimental and control groups. The experimental group showed a significant increase in baseline FHR after SBE within the normal range, and after SBE, it reduced to the FHR before SBE. The variability, acceleration and deceleration of FHR before and after SBE did not differ significantly between two groups. Moreover, there was no statistically significant difference before and after SBE in the experimental group. Also, the experimental group showed statistically significant decreases in physical discomfort score. However, there were no significant differences in depression and anxiety score between two groups. CONCLUSIONS: SBE in hospitalized high-risk pregnant women under bed rest did not increase the risk to the fetus, and relieved physical discomfort and anxiety. Therefore, SBE should be considered as a nursing intervention in hospitalized high-risk pregnant women. PMID- 29463486 TI - Burnout Study of Clinical Nurses in Vietnam: Development of Job Burnout Model Based on Leiter and Maslach's Theory. AB - PURPOSE: This study aimed to create a Vietnamese version of both the Maslach Burnout Inventory-General Survey (MBI-GS) and Areas of Worklife Scale (AWS) to assess the burnout state of Vietnamese clinical nurses and to develop a causal model of burnout of clinical nurses. METHODS: We conducted a descriptive design using a cross-sectional survey. The questionnaire was hand divided directly by nursing departments to 500 clinical nurses in three hospitals. Vietnamese MBI-GS and AWS were then examined for reliability and validity. We used the revised exhaustion +1 burnout classification to access burnout state. We performed path analysis to develop a Vietnamese causal model based on the original model by Leiter and Maslach's theory. RESULTS: We found that both scales were reliable and valid for assessing burnout. Among nurse participants, the percentage of severe burnout was 0.7% and burnout was 15.8%, and 17.2% of nurses were exhausted. The best predictor of burnout was "on-duty work schedule" that clinical nurses have to work for 24 hours. In the causal model, we also found similarity and difference pathways in comparison with the original model. CONCLUSION: Vietnamese MBI-GS and AWS were applicable to research on occupational stress. Nearly one fifth of Vietnamese clinical nurses were working in burnout state. The causal model suggested a range of factors resulting in burnout, and it is necessary to consider the specific solution to prevent burnout problem. PMID- 29463488 TI - Digital Health Interventions for Adults With Type 2 Diabetes: Qualitative Study of Patient Perspectives on Diabetes Self-Management Education and Support. AB - BACKGROUND: The prevalence of type 2 diabetes is increasing globally, and health services in many countries are struggling with the morbidity, mortality, and costs associated with the complications of this long-term condition. Diabetes self-management education (DSME) and behavioral support can reduce the risks of developing diabetes-related complications and improve glycemic control. However, their uptake is low. Digital health interventions (DHI) can provide sustained support and may overcome challenges associated with attending diabetes self management sessions. They have the potential for delivery at multiple locations at convenient times, anonymity, and presentation of content in attractive and tailored formats. This study investigates the needs and wants of patients with type 2 diabetes to inform the development of digital self-management education and support. OBJECTIVE: The objective of this study was to explore patient perspectives on unmet needs for self-management and support and the role of DHI in adults living with type 2 diabetes. METHODS: This study used a qualitative approach based on data generated from 4 focus groups with 20 patients. RESULTS: The data generated by the focus groups illustrated the significant burden that the diagnosis of diabetes places on many patients and the negative impacts on their emotional well-being, work, social life, and physical health. Although patients' experiences of the health care services varied, there was agreement that even the best services were unable to meet all users' needs to support the emotional regulation, psychological adjustment, and behavioral changes needed for successful self-management. CONCLUSIONS: By focusing on medical management and information provision, existing health care services and education programs may not be adequately meeting all the needs of patients with type 2 diabetes. DHIs have the potential to improve access to DSME and behavioral support and extend the range of content offered by health services to fit with a wider range of patient needs. Features that could help DHIs address some of the unmet needs described by participants in this study included placing an emphasis on emotional and role management, being available at all times, having up-to-date evidence based guidance for patients, and providing access to peer-generated and professional advice. PMID- 29463487 TI - Users, Uses, and Effects of Social Media in Dietetic Practice: Scoping Review of the Quantitative and Qualitative Evidence. AB - BACKGROUND: Social media platforms are increasingly used by registered dietitians (RDs) to improve knowledge translation and exchange in nutrition. However, a thorough understanding of social media in dietetic practice is lacking. OBJECTIVE: The objective of this study was to map and summarize the evidence about the users, uses, and effects of social media in dietetic practice to identify gaps in the literature and inform future research by using a scoping review methodology. METHODS: Stages for conducting the scoping review included the following: (1) identifying the research question; (2) identifying relevant studies through a comprehensive multidatabase and gray literature search strategy; (3) selecting eligible studies; (4) charting the data; and (5) collating, summarizing, and reporting results for dissemination. Finally, knowledge users (RDs working for dietetic professional associations and public health organizations) were involved in each review stage to generate practical findings. RESULTS: Of the 47 included studies, 34 were intervention studies, 4 were descriptive studies, 2 were content analysis studies, and 7 were expert opinion papers in dietetic practice. Discussion forums were the most frequent social media platform evaluated (n=19), followed by blogs (n=13) and social networking sites (n=10). Most studies targeted overweight and obese or healthy users, with adult populations being most studied. Social media platforms were used to deliver content as part of larger multiple component interventions for weight management. Among intervention studies using a control group with no exposition to social media, we identified positive, neutral, and mixed effects of social media for outcomes related to users' health behaviors and status (eg, dietary intakes and body weight), participation rates, and professional knowledge. Factors associated with the characteristics of the specific social media, such as ease of use, a design for quick access to desired information, and concurrent reminders of use, were perceived as the main facilitators to the use of social media in dietetic practice, followed to a lesser extent by interactions with an RD and social support from fellow users. Barriers to social media use were mostly related to complicated access to the site and time issues. CONCLUSIONS: Research on social media in dietetic practice is at its infancy, but it is growing fast. So far, this field of research has targeted few social media platforms, most of which were assessed in multiple-component interventions for weight management among overweight or obese adults. Trials isolating the effects and mechanisms of action of specific social media platforms are needed to draw conclusions regarding the effectiveness of those tools to support dietetic practice. Future studies should address barriers and facilitators related to the use of social media written by RDs and should explore how to make these tools useful for RDs to reach health consumers to improve health through diet. PMID- 29463489 TI - Mobile App Delivery of the EORTC QLQ-C30 Questionnaire to Assess Health-Related Quality of Life in Oncological Patients: Usability Study. AB - BACKGROUND: Mobile apps are evolving in the medical field. However, ongoing discussions have questioned whether such apps are really valuable and whether patients will accept their use in day-to-day clinical life. Therefore, we initiated a usability study in our department. OBJECTIVE: We present our results of the first app prototype and patient testing of health-related quality of life (HRQoL) assessment in oncological patients. METHODS: We developed an app prototype for the iOS operating system within eight months in three phases: conception, initial development, and pilot testing. For the HRQoL assessment, we chose to implement only the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30 (QLQ-C30; German version 3). Usability testing was conducted for three months. Participation was voluntary and pseudonymized. After completion of the QLQ-C30 questionnaire using iPads provided by our department, we performed a short survey with 10 questions. This survey inquired about patients' opinions regarding general aspects, including technical advances in medicine, mobile and app assistance during cancer treatment, and the app-specific functions (eg, interface and navigation). RESULTS: After logging into the app, the user can choose between starting a questionnaire, reviewing answers (administrators only), and logging out. The questionnaire is displayed with the same information, questions, and answers as on the original QLQ-C30 sheet. No alterations in wording were made. Usability was tested with 81 patients; median age was 55 years. The median time for completing the HRQoL questionnaire on the iPad was 4.0 minutes. Of all participants, 84% (68/81) owned a mobile device. Similarly, 84% (68/81) of participants would prefer a mobile version of the HRQoL questionnaire instead of a paper-based version. Using the app in daily life during and after cancer treatment would be supported by 83% (67/81) of participants. In the prototype version of the app, data were stored on the device; in the future, 79% (64/81) of the patients would agree to transfer data via the Internet. CONCLUSIONS: Our usability test showed good results regarding attractiveness, operability, and understandability. Moreover, our results demonstrate a high overall acceptance of mobile apps and telemedicine in oncology. The HRQoL assessment via the app was accepted thoroughly by patients, and individuals are keen to use it in clinical routines, while data privacy and security must be ensured. PMID- 29463490 TI - Motivational Interviewing and Medication Review in Coronary Heart Disease (MIMeRiC): Protocol for a Randomized Controlled Trial Investigating Effects on Clinical Outcomes, Adherence, and Quality of Life. AB - BACKGROUND: Preventive treatment goals for blood pressure and cholesterol levels continue to be unmet for many coronary patients. The effect of drug treatment depends on both its appropriateness and the patients' adherence to the treatment regimen. There is a need for adherence interventions that have a measurable effect on clinical outcomes. OBJECTIVE: This study aims to evaluate the effects on treatment goals of an intervention designed to improve patient adherence and treatment quality in secondary prevention of coronary heart disease. A protocol for the prespecified process evaluation of the trial is published separately. METHODS: The Motivational Interviewing and Medication Review in Coronary heart disease (MIMeRiC) trial is a prospective, randomized, outcomes-blinded trial designed to compare individualized follow-up by a clinical pharmacist using motivational interviewing (MI) and medication review with standard follow-up. Patients were randomized to 2 groups after stratification according to their beliefs about medicines. After standard follow-up at the cardiology clinic, patients in the intervention group are seen individually by a clinical pharmacist 2 to 5 times as required over 7 months, at the clinic. The pharmacist reviews each patient's medication and uses MI to manage any problems with prescribing and adherence. The primary study outcome is the proportion of patients who have reached the treatment goal for low-density lipoprotein cholesterol by 12 months after discharge. Secondary outcomes are the effects on patient adherence, systolic blood pressure, disease-specific quality of life, and health care use. RESULTS: The protocol for this study was approved by the Regional Ethics Committee, Linkoping, in 2013. Enrollment started in October 2013 and ended in December 2016 when 417 patients had been included. Follow-up data collection will conclude in March 2018. Publication of the primary and secondary outcome results from the MIMeRiC trial is anticipated in 2019. CONCLUSIONS: The MIMeRiC trial will assess the effectiveness of an intervention involving medication reviews and individualized support. The results will inform the continued development of support for this large group of patients who use preventive medicines for lifelong treatment. The design of this adherence intervention is based on a theoretical framework and is the first trial of an intervention that uses beliefs about medicines to individualize the intervention protocol.

PMID- 29463492 TI - Ecuadorian Cancer Patients' Preference for Information and Communication Technologies: Cross-Sectional Study. AB - BACKGROUND: The instantaneous spread of information, low costs, and broad availability of information and communication technologies (ICTs) make them an attractive platform for managing care, patient communication, and medical interventions in cancer treatment. There is little information available in Latin America about the level of usage of ICTs for and by cancer patients. Our study attempts to fill this gap. OBJECTIVE: The aim of this study was to assess the level of ICT use and patterns of preferences among cancer patients. METHODS: We conducted an anonymous cross-sectional survey study in 500 Ecuadorian cancer patients. This questionnaire consisted of 22 items about demographic and clinical data, together with the preferences of people who use ICTs. Chi-square, crude, and adjusted logistic regressions were performed. RESULTS: Of the total, 43.2% (216/500) of participants reported that they had access to the Internet, and 25.4% (127/500) reported that they neither owned a cell phone nor did they have access to the Internet. The Internet constituted the highest usage rate as a source of information about malignant diseases (74.3%, 162/218) regardless of age (P<.001). With regard to the preferences on how patients would like to use ICTs to receive information about diseases, WhatsApp (66.5%, 145/218) and short message service (SMS) text messaging (61.0%, 133/218) were widely reported as interesting communication channels. Similarly, WhatsApp (72.0%, 157/218) followed by SMS (63.8%, 139/218) were reported as the preferred ICTs through which patients would like to ask physicians about diseases. Adjusted regression analysis showed that patients aged between 40 and 64 years were more likely to be interested in receiving information through SMS (odds ratio, OR 5.09, 95% CI 1.92 13.32), as well as for asking questions to physicians through this same media (OR 9.78, CI 3.45-27.67) than the oldest group. CONCLUSIONS: WhatsApp, SMS, and email are effective and widely used ICTs that can promote communication between cancer patients and physicians. According to age range, new ICTs such as Facebook are still emerging. Future studies should investigate how to develop and promote ICT based resources more effectively to engage the outcomes of cancer patients. The widespread use of ICTs narrows the gap between cancer patients with restricted socioeconomic conditions and those with wealth and easily available technological means, thereby opening up new possibilities in low-income countries. PMID- 29463491 TI - A Smartphone App to Promote an Active Lifestyle in Lower-Educated Working Young Adults: Development, Usability, Acceptability, and Feasibility Study. AB - BACKGROUND: Physical activity (PA) levels are problematic in lower-educated working young adults (18-26 years). To promote PA, smartphone apps have great potential, but there is no evidence for their effectiveness in this population. To increase the likelihood that a newly developed app will be effective, formative research and user testing are required. OBJECTIVE: The aim of this study was to describe the development, usability, acceptability, and feasibility of a new theory- and evidence-based smartphone app to promote an active lifestyle in lower-educated working young adults. METHODS: The new app was developed by applying 4 steps. First, determinants important to promote an active lifestyle in this population were selected. Second, evidence-based behavior change techniques were selected to convert the determinants into practical applications. Third, a new smartphone app was developed. Fourth, volunteers (n=11, both lower and higher educated) tested the app on usability, and lower-educated working young adults (n=16) tested its acceptability and feasibility via (think aloud) interviews, a questionnaire, and Google Analytics. The app was accordingly adapted for the final version. RESULTS: A new Android app, Active Coach, was developed that focused on knowledge, attitude, social support, and self-efficacy (based on outcomes from step 1), and that applied self-regulation techniques (based on outcomes from step 2). The app consists of a 9-week program with personal goals, practical tips, and scientific facts to encourage an active lifestyle. To ensure all-day and automatic self-monitoring of the activity behavior, the Active Coach app works in combination with a wearable activity tracker, the Fitbit Charge. Issues detected by the usability test (eg, text errors, wrong messages) were all fixed. The acceptability and feasibility test showed that participants found the app clear, understandable, and motivating, although some aspects needed to be more personal. CONCLUSIONS: By applying a stepwise, user-centered approach that regularly consulted the target group, the new app is adapted to their specific needs and preferences. The Active Coach app was overall positively evaluated by the lower-educated working young adults at the end of the development process. PMID- 29463493 TI - Effect of Impulsive Compression Treatment on Postoperative Complications After Open Peripheral Vascular Revascularization (In Situ): Protocol for a Randomized Control Trial. AB - BACKGROUND: In patients with critical leg ischemia (CLI), the standard operative choice is an in situ bypass to the lower extremity to improve the patients' prognosis and quality of life. Postoperative complications after surgery occur in 18 % of the patients, prolonging hospitalization and convalescence. The main operative complication is edema. This can be prevented by early mobilization or stimulation of the natural venous pump in the leg. OBJECTIVE: To investigate whether compression therapy with foot pump reduces postoperative edema, facilitates wound healing of the operation wounds, promotes healing of ischemic ulcers, and shortens hospitalization, increasing and improving the patient's subjective quality of life faster. METHODS: The protocol is designed as a randomized, unblinded prospective study with 50 patients in each group. Standard postoperative routines after bypass surgery, including short-stretch bandaging of the operated legs, are compared to supportive stimulation of the venous pump by an impulsive compression foot pump. The postoperative edema of the leg is measured 10 cm below the patella and 8 cm proximal to the medial malleolus. Measurements are performed preoperatively, 1 and 4 days postoperatively and at discharge. RESULTS: The primary endpoint is reduction of leg edema by at least 50%. The secondary endpoint includes earlier mobilization in the pump group and decreased length of stay in hospital. Quality of life is evaluated through the European Health Related Quality of Life Questionnaire 5 Dimensions (EQ-5D) and Vascular Quality of Life Questionnaire-6 (VascuQol-6) questionnaires. The start of the study is February 1, 2018, and the end of the study is February 1, 2020. First results will be available April 2020. CONCLUSIONS: In orthopedic surgery of the lower extremities, the use of foot pumps has shown a reduction of edema and thrombosis in risk patients. Although important positive effects may be expected after vein bypass surgery, no reports have yet investigated the use of the device in vascular-operated patients and no analysis or meta Cochrane reviews are available in this field.

PMID- 29463494 TI - How Health Care Professionals Evaluate a Digital Intervention to Improve Medication Adherence: Qualitative Exploratory Study. AB - BACKGROUND: Medication nonadherence poses a serious and a hard-to-tackle problem for many chronic diseases. Electronic health (eHealth) apps that foster patient engagement and shared decision making (SDM) may be a novel approach to improve medication adherence. OBJECTIVE: The aim of this study was to investigate the perspective of health care professionals regarding a newly developed digital app aimed to improve medication adherence. Familial hypercholesterolemia (FH) was chosen as a case example. METHODS: A Web-based prototype of the eHealth app-MIK was codesigned with patients and health care professionals. After user tests with patients, we performed semistructured interviews and user tests with 12 physicians from 6 different hospitals to examine how the functionalities offered by MIK could assist physicians in their consultation and how they could be integrated into daily clinical practice. Qualitative thematic analysis was used to identify themes that covered the physicians' evaluations. RESULTS: On the basis of the interview data, 3 themes were identified, which were (1) perceived impact on patient-physician collaboration; (2) perceived impact on the patient's understanding and self-management regarding medication adherence; and (3) perceived impact on clinical decisions and workflow. CONCLUSIONS: The eHealth app MIK seems to have the potential to improve the consultation between the patient and the physician in terms of collaboration and patient engagement. The impact of eHealth apps based on the concept of SDM for improving medication-taking behavior and clinical outcomes is yet to be evaluated. Insights will be useful for further development of eHealth apps aimed at improving self-management by means of patient engagement and SDM.

PMID- 29463495 TI - Healthy Body Image Intervention Delivered to Young Women via Facebook Groups: Formative Study of Engagement and Acceptability. AB - BACKGROUND: There is increasing interest in using social media sites such as Facebook to deliver health interventions so as to expose people to content while they are engaging in their usual social media habit. This formative intervention development study is novel in describing a preliminary test of using the secret group feature of Facebook to deliver a behavioral intervention targeting users of indoor tanning beds to reduce their risk of skin cancer. Intervention content was designed to challenge body image-related constructs associated with indoor tanning through the use of dissonance-inducing content. OBJECTIVE: To evaluate engagement with and acceptability of using a secret Facebook group to deliver a healthy body image intervention to young women engaged in indoor tanning. METHODS: Seventeen young women completed a baseline survey and joined a secret Facebook group with intervention content delivered via daily posts for 4 weeks. Engagement data was extracted and acceptability was measured via a follow-up survey. RESULTS: The study had a high retention rate (94%, [16/17]). On average, posts were viewed by 91% of participants, liked by 35%, and commented on by 26%. The average comment rate was highest (65%) for posts that elicited comments by directly posing questions or discussion topics to the group. Average intervention acceptability ratings were highly positive and participants reported feeling connected to the group and its topic. Average rates of past 1-month indoor tanning reported following the intervention were lower than the baseline rate (P=.08, Cohen d=0.47). CONCLUSIONS: This study is novel in demonstrating participant engagement with and acceptability of using Facebook secret groups to deliver a dissonance-inducing intervention approach that utilizes group-based discussions related to body image. The study is also unique within the field of skin cancer prevention by demonstrating the potential value of delivering an indoor tanning intervention within an interactive social media format. The findings suggest that Facebook metrics of intervention post engagement (ie, likes and comments) may vary based on post types and that designing specifically labeled discussion posts may be helpful for soliciting engagement as well as challenging beliefs. PMID- 29463497 TI - Psychological interventions used to reduce sports injuries: a systematic review of real-world effectiveness. AB - OBJECTIVE: To systematically review studies examining the role of psychological interventions in injury prevention. The primary research question was: What is the real-world effectiveness of psychological intervention in preventing sports injuries? DESIGN: Mixed methods systematic review with best evidence synthesis. DATA SOURCES: CINAHL, MEDLINE, PsycARTICLES, PsycINFO, SPORTDiscus, Science Direct and PubMed. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Randomised controlled trials (RCT), non-RCTs that included a comparison group, before and after study designs and qualitative methods. Studies were required to outline specific unimodal or multimodal psychological interventions used in relation to injury prevention in the real-world setting. OUTCOME MEASURE: Studies were independently appraised with the Mixed Methods Appraisal Tool. RESULTS: Thirteen papers (incorporating 14 studies) met the eligibility criteria, of which 93% (13/14) reported a decrease in injury rates (effect size range=0.2-1.21). There was an overall moderate risk of bias in reporting (52%). There is a dominance of stress management-based interventions in literature due to the prominence of the model of stress and athletic injury within the area. SUMMARY/CONCLUSIONS: Psychological interventions demonstrate small (0.2) to large (1.21) effects on sports injury rates. The research area demonstrates a cumulative moderate risk in reporting bias (52%). PROSPERO REGISTRATION NUMBER: CRD42016035879.

PMID- 29463502 TI - Optical coherence tomography angiography in pseudophakic cystoid macular oedema compared to diabetic macular oedema: qualitative and quantitative evaluation of retinal vasculature. AB - AIMS: To describe optical coherence tomography angiography (OCT-A) abnormalities of patients with pseudophakic cystoid macular oedema (PCMO) before and after pharmacological resolution, compared with diabetic macular oedema (DMO) and normal eyes. METHODS: In this retrospective, observational study, 44 eyes (30 patients) were included: 15 eyes (15 patients) affected by PCMO; 14 healthy fellow eyes used as negative control group; 15 eyes (15 age-matched and sex matched patients) with DMO used as positive control group. All patients underwent a complete ophthalmological examination at baseline, including OCT-A scans of the macula through AngioPlex CIRRUS-5000 (Carl Zeiss Meditec, Dublin, USA). Patients with PCMO and DMO were re-evaluated after the pharmacological resolution of cystoid macular oedema (CMO). RESULTS: Disruption of parafoveal capillary arcade and cystoid spaces in deep capillary plexus (DCP) were frequent in patients with PCMO and DMO (73% and 100%, 87% and 100%). Capillary abnormalities and non perfusion greyish areas in DCP were more frequent in DMO (P<0.001 and P=0.014). Patients with PCMO showed a larger foveal avascular zone area in DCP at baseline (P<0.001), which significantly reduced after treatment (P=0.001). Vessel density of full-thickness retina and DCP was reduced in patients with PCMO (P=0.022 and P=0.001), and no changes were observed after treatment. Interestingly, DCP appeared less represented in patients with DMO than PCMO subjects (P=0.001). CONCLUSIONS: Patients with PCMO have an impairment of mainly DCP, partially reversible after treatment. Furthermore, we disclosed that different alterations of the retinal vasculature characterise CMO derived from two different diseases, namely PCMO and DMO, and this could be due to their distinct pathophysiology.

AB - Maternal glycemia is a key determinant of birth weight, but recent large-scale genome-wide association studies demonstrated an important contribution of fetal genetics. It is not known whether fetal genotype modifies the impact of maternal glycemia or whether it acts through insulin-mediated growth. We tested the effects of maternal fasting plasma glucose (FPG) and a fetal genetic score for birth weight on birth weight and fetal insulin in 2,051 European mother-child pairs from the Exeter Family Study of Childhood Health (EFSOCH) and the Hyperglycemia and Adverse Pregnancy Outcome (HAPO) study. The fetal genetic score influenced birth weight independently of maternal FPG and impacted growth at all levels of maternal glycemia. For mothers with FPG in the top tertile, the frequency of large for gestational age (birth weight >=90th centile) was 31.1% for offspring with the highest tertile genetic score and only 14.0% for those with the lowest tertile genetic score. Unlike maternal glucose, the fetal genetic score was not associated with cord insulin or C-peptide. Similar results were seen for HAPO participants of non-European ancestry (n = 2,842 pairs). This work demonstrates that for any level of maternal FPG, fetal genetics has a major impact on fetal growth and acts predominantly through independent mechanisms.

AB - New findings suggest that postmenopausal women with high levels of body fat are at increased risk of ER-positive breast cancer, even if their body mass index is within the normal range. If confirmed, these results would put many more women at elevated risk for breast cancer than was previously thought, with implications for the way that healthy-weight women should be counseled to reduce their health risks.

PMID- 29463509 TI - Ventricular Fibrillation Conversion Testing After Implantation of a Subcutaneous Implantable Cardioverter Defibrillator: Report From the National Cardiovascular Data Registry. AB - BACKGROUND: Compared with transvenous implantable cardioverter defibrillators (ICDs), subcutaneous (S)-ICDs require a higher energy for effective defibrillation. Although ventricular fibrillation conversion testing (CT) is recommended after S-ICD implantation to ensure an adequate margin between the defibrillation threshold and maximum device output (80J), prior work found that adherence to this recommendation is declining. METHODS: We studied first-time recipients of S-ICDs (between September 28, 2012, and April 1, 2016) in the National Cardiovascular Database Registry ICD Registry to determine predictors of use of CT, predictors of an insufficient safety margin (ISM, defined as ventricular fibrillation conversion energy >65J) during testing, and inhospital outcomes associated with use of CT. Multivariable logistic regression analysis was used to predict use of CT and ISM. Inverse probability weighted logistic regression analysis was used to examine the association between use of CT and inhospital adverse events including death. RESULTS: CT testing was performed in 70.7% (n=5624) of 7960 patients with S-ICDs. Although deferral of CT was associated with several patient characteristics (including increased body mass index, increased body surface area, severely reduced ejection fraction, dialysis dependence, warfarin use, anemia, and hypertrophic cardiomyopathy), the facility effect was comparatively more important (area under the curve for patient level versus generalized linear mixed model: 0.619 versus 0.877). An ISM occurred in 6.9% (n=336) of 4864 patients without a prior ICD and was more common among white patients and those with ventricular pacing on the preimplant ECG, higher preimplant blood pressure, larger body surface area, higher body mass index, and lower ejection fraction. A risk score was able to identify patients at low (<5%), medium (5% to 10%), and high risk (>10%) for ISM. CT testing was not associated with a composite of inhospital complications including death. CONCLUSIONS: Use of CT testing after S-ICD implantation was driven by facility preference to a greater extent than patient factors and was not associated with a composite of inhospital complications or death. ISM was relatively uncommon and is associated with several widely available patient characteristics. These data may inform ICD system selection and a targeted approach to CT. PMID- 29463510 TI - Device Thrombosis After Percutaneous Left Atrial Appendage Occlusion Is Related to Patient and Procedural Characteristics but Not to Duration of Postimplantation Dual Antiplatelet Therapy. AB - BACKGROUND: Device-related thrombus (DRT) after left atrial appendage occlusion is a worrisome finding with little knowledge about when to expect it and how to prevent it. This study sought to investigate correlates of DRT after left atrial appendage occlusion, its time of diagnosis, and particularly, association with postimplantation dual antiplatelet therapy duration. METHODS AND RESULTS: Consecutive patients (n=102) after left atrial appendage occlusion with AMPLATZER Cardiac Plug/Amulet (n=59) or WATCHMAN (n=43) were included in a prospective registry (October 2011-May 2016). Follow-up was done at 1.5, 3 to 6, and 12 months postimplantation. DRT was classified as early (at 1.5 month), late (at 3-6 month), or very late (at 12-month follow-up). Postimplantation dual antiplatelet therapy was recommended for 30 to 180 days and decided independently by attending physicians. Final analysis included 99 patients, 42 (42.4%) females, with median CHA2DS2-VASc of 4.0 (interquartile range [IQR], 3.0-5.0) and median HAS-BLED score of 2.0 (IQR, 1.0-3.0). DRTs were observed in 7 (7.1%) patients: 2 (28.6%) early, 2 (28.6%) late, and 3 (42.9%) very late. When compared with patients without DRT, those with DRT presented more often with a history of prior thromboembolism (5 [71.4%] versus 28 [30.4%]; P=0.04), had lower left ventricular ejection fraction (50.0 [IQR, 35.0-55.0] versus 60.0 [IQR, 55.0-66.0]; P<0.01), and had greater proportion of patients with deep device implantation (6 [85.7%] versus 36 [39.1%]; P=0.04) and with larger devices implanted (30.0 mm [IQR, 27.0 33.0] versus 25.0 mm [IQR, 24.0-28.0]; P<0.01). Postimplantation dual antiplatelet therapy duration was not different between the 2 groups (12.4 weeks [IQR, 6.0-49.7] with DRT versus 13.0 weeks [IQR, 7.3-26.0] without DRT; P=0.77). CONCLUSIONS: In this real-world series, DRT was observed early, late, and very late after left atrial appendage occlusion. It was related to patient and procedural characteristics but not to postimplantation dual antiplatelet therapy duration. PMID- 29463511 TI - What Lies Beneath Left Atrial Appendage Occlusion: Know Your Enemy. PMID- 29463513 TI - Metabolism of the Pacific oyster, Crassostrea gigas, is influenced by salinity and modulates survival to the Ostreid herpesvirus OsHV-1. AB - The Pacific oyster, Crassostrea gigas, is an osmoconforming bivalve exposed to wide salinity fluctuations. The physiological mechanisms used by oysters to cope with salinity stress are energy demanding and may impair other processes, such as defense against pathogens. This oyster species has been experiencing recurrent mortality events caused by the Ostreid herpesvirus 1 (OsHV-1). The objectives of this study were to investigate the effect of salinity (10, 15, 25 and 350/00) on energetic reserves, key enzyme activities and membrane fatty acids, and to identify the metabolic risk factors related to OsHV-1-induced mortality of oysters. Acclimation to low salinity led to increased water content, protein level, and energetic reserves (carbohydrates and triglycerides) of oysters. The latter was consistent with lower activity of hexokinase, the first enzyme involved in glycolysis, up-regulation of AMP-activated protein kinase, a major regulator of cellular energy metabolism, and lower activity of catalase, an antioxidant enzyme involved in management of reactive oxygen species. Acclimation to salinity also involved a major remodeling of membrane fatty acids. Particularly, 20:4n-6 decreased linearly with decreasing salinity, likely reflecting its mobilization for prostaglandin synthesis in oysters. The survival of oysters exposed to OsHV-1 varied from 43% to 96% according to salinity ( Fuhrmann et al., 2016). Risk analyses showed that activity of superoxide dismutase and levels of proteins, carbohydrates, and triglycerides were associated with a reduced risk of death. Therefore, animals with a higher antioxidant activity and a better physiological condition seemed less susceptible to OsHV-1. PMID- 29463515 TI - Timing and context of dolphin clicks during and after mine simulator detection and marking in the open ocean. AB - Two dolphins carrying cameras swam in the ocean as they searched for and marked mine simulators - buried, proud or moored. As the animals swam ahead of a boat they searched the ocean. Cameras on their harness recorded continuous sound and video. Once a target was detected, the dolphins received a marker to take to the simulator's location. During search and detection, dolphins made almost continuous trains of varying interval clicks. During the marking phase, shorter click trains were interrupted by periods of silence. As the dolphins marked simulators, they often produced victory squeals - pulse bursts that vary in duration, peak frequency and amplitude. Victory squeals were produced on 72% of marks. Sometimes after marking, or at other times during their long swims, the dolphins produced click packets. Packets typically consisted of two to 10 clicks with inter-click intervals of 7-117 ms followed by a silence of 223-983 ms. Click packets appeared unrelated with searching or marking. We suggest that the packets were used to improve signal to noise ratios for locating a boat or other distant object. Victory squeals produced when marking the targets suggest to us that the dolphins know when they have succeeded in this multipart task. PMID- 29463514 TI - Ecdysone signaling regulates specification of neurons with a male-specific neurite in Drosophila. AB - Some mAL neurons in the male brain form the ipsilateral neurite (ILN[+]) in a manner dependent on FruBM, a male-specific transcription factor. FruBM represses robo1 transcription, allowing the ILN to form. We found that the proportion of ILN[+]-mALs in all observed single cell clones dropped from ~90% to ~30% by changing the heat-shock timing for clone induction from 4-5 days after egg laying (AEL) to 6-7 days AEL, suggesting that the ILN[+]-mALs are produced predominantly by young neuroblasts. Upon EcR-A knockdown, ILN[+]-mALs were produced at a high rate (~60%), even when heat shocked at 6-7 days AEL, yet EcR-B1 knockdown reduced the proportion of ILN[+]-mALs to ~30%. Immunoprecipitation assays in S2 cells demonstrated that EcR-A and EcR-B1 form a complex with FruBM. robo1 reporter transcription was repressed by FruBM and ecdysone counteracted FruBM. We suggest that ecdysone signaling modulates the FruBM action to produce an appropriate number of male-type neurons. PMID- 29463516 TI - Sustained exercise-trained juvenile black carp (Mylopharyngodon piceus) at a moderate water velocity exhibit improved aerobic swimming performance and increased postprandial metabolic responses. AB - The objectives of this study were to examine whether sustained exercise training at four water velocities, i.e. nearly still water (control), 1 body length (BL) s 1, 2 BL s-1 and 4 BL s-1, has effects on swimming performance and digestive metabolism in juvenile black carp (Mylopharyngodon piceus). The results demonstrated that fish subjected to sustained training at 2 and 4 BL s-1 showed significantly higher critical swimming speed (Ucrit) and maximum metabolic rate (MMR) over the control group. Fish subjected to sustained training at 1 and 2 BL s-1 showed a significantly (30 and 54%) prolonged duration, 14 and 17% higher postprandial MO2 increment (i.e. MO2peak), and 62 and 92% more energy expended on specific dynamic action (SDA), respectively, after consuming a similar meal over fish kept in nearly still water. These results suggest that (1) sustained exercise training at a higher speed (2 or 4 BL s-1) had a positive influence on the aerobic swimming performance of juvenile M. piceus, which may be associated with improved aerobic metabolism; and (2) sustained exercise training at a lower speed (1 or 2 BL s-1) resulted in elevated postprandial metabolic responses in juvenile M. piceus. PMID- 29463517 TI - Common measure of quality of life for people with systemic sclerosis across seven European countries: a cross-sectional study. AB - OBJECTIVES: The aim of this study was to adapt the Systemic Sclerosis Quality of Life Questionnaire (SScQoL) into six European cultures and validate it as a common measure of quality of life in systemic sclerosis (SSc). METHODS: This was a seven-country (Germany, France, Italy, Poland, Spain, Sweden and UK) cross sectional study. A forward-backward translation process was used to adapt the English SScQoL into target languages. SScQoL was completed by patients with SSc, then data were validated against the Rasch model. To correct local response dependency, items were grouped into the following subscales: function, emotion, sleep, social and pain and reanalysed for fit to the model, unidimensionality and cross-cultural equivalence. RESULTS: The adaptation of the SScQoL was seamless in all countries except Germany. Cross-cultural validation included 1080 patients with a mean age 58.0 years (SD 13.9) and 87% were women. Local dependency was evident in individual country data. Grouping items into testlets corrected the local dependency in most country specific data. Fit to the model, reliability and unidimensionality was achieved in six-country data after cross-cultural adjustment for Italy in the social subscale. The SScQoL was then calibrated into an interval level scale. CONCLUSION: The individual SScQoL items have translated well into five languages and overall, the scale maintained its construct validity, working well as a five-subscale questionnaire. Measures of quality of life in SSc can be directly compared across five countries (France, Poland Spain, Sweden and UK). Data from Italy are also comparable with the other five countries although require an adjustment. PMID- 29463518 TI - Relationship between serum urate concentration and clinically evident incident gout: an individual participant data analysis. AB - OBJECTIVES: To provide estimates of the cumulative incidence of gout according to baseline serum urate. METHODS: Using individual participant data from four publicly available cohorts (Atherosclerosis Risk in Communities Study, Coronary Artery Risk Development in Young Adults Study, and both the Original and Offspring cohorts of the Framingham Heart Study), the cumulative incidence of clinically evident gout was calculated according to baseline serum urate category. Cox proportional hazards modelling was used to evaluate the relation of baseline urate categories to risk of incident gout. RESULTS: This analysis included 18 889 participants who were gout-free at baseline, with mean (SD) 11.2 (4.2) years and 212 363 total patient-years of follow-up. The cumulative incidence at each time point varied according to baseline serum urate concentrations, with 15-year cumulative incidence (95% CI) ranging from 1.1% (0.9 to 1.4) for <6 mg/dL to 49% (31 to 67) for >=10 mg/dL. Compared with baseline serum urate <6 mg/dL, the adjusted HR for baseline serum urate 6.0-6.9 mg/dL was 2.7, for 7.0-7.9 mg/dL was 6.6, for 8.0-8.9 mg/dL was 15, for 9.0-9.9 mg/dL was 30, and for >=10 mg/dL was 64. CONCLUSIONS: Serum urate level is a strong non linear concentration-dependent predictor of incident gout. Nonetheless, only about half of those with serum urate concentrations >=10mg/dL develop clinically evident gout over 15 years, implying a role for prolonged hyperuricaemia and additional factors in the pathogenesis of gout. PMID- 29463519 TI - Effect of pregnancy on disease flares in patients with systemic lupus erythematosus. AB - OBJECTIVE: Prior studies found conflicting results about whether lupus is likely to flare during or after pregnancy. Using a large cohort of pregnant and non pregnant women with lupus, we estimated the effect of pregnancy on disease flares in systemic lupus erythematosus. METHODS: Data were collected in the Hopkins Lupus Cohort 1987-2015. Women aged 14-45 years with >1 measurement of disease activity were included. The time-varying exposures were classified as pregnancy, postpartum or non-pregnant/non-postpartum periods. Flares were defined as: (1) change in Physician Global Assessment (PGA)>=1 from previous visit and (2) change in Safety of Estrogens in Lupus National Assessment-Systemic Lupus Erythematosus Disease Activity Index (SELENA-SLEDAI)>=4 from previous visit. A stratified Cox model estimated HRs with bootstrap 95% CIs. RESULTS: There were 1349 patients, including 398 pregnancies in 304 patients. There was an increased rate of flare defined by PGA during pregnancy (HR: 1.59; 95% CI 1.27 to 1.96); however, this effect was modified by hydroxychloroquine (HCQ) use, with the HR of flares in pregnancy compared with non-pregnant/non-postpartum periods estimated to be 1.83 (95% CI 1.34 to 2.45) for patients with no HCQ use and 1.26 (95% CI 0.88 to 1.69) for patients with HCQ use. The risk of flare was similarly elevated among non-HCQ users in the 3 months postpartum, but not for women taking HCQ after delivery. CONCLUSIONS: Our study supports and extends previous findings that the incidence of flare is increased during pregnancy and within the 3 months postpartum. Continuing HCQ, however, appeared to mitigate the risk of flare during and after pregnancy. PMID- 29463521 TI - Recent advances in the management of childhood dental caries.

AB - OBJECTIVES: Lipid profiles are altered by active disease in patients with rheumatoid arthritis (RA) and may be further modified by treatment with Janus kinase inhibitors and other disease-modifying antirheumatic drugs. METHODS: Lipid data were analysed from phase II and III studies of 4 mg (n=997) and 2 mg (n=479) oral baricitinib administered once daily in patients with moderate-to-severe active RA. Lipoprotein particle size and number and GlycA were evaluated with nuclear magnetic resonance in one phase III study. The effect of statin therapy on lipid levels was evaluated in patients on statins at baseline and in patients who initiated statins during the study. RESULTS: Treatment with baricitinib was associated with increased levels of total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and triglycerides, but no significant change in LDL-C:HDL-C ratio. Lipid levels plateaued after 12 weeks of treatment. Baricitinib treatment increased large LDL and decreased small, dense LDL particle numbers and GlycA. Lipid changes from baseline were not significantly different between baseline statin users and non users. In patients who initiated statin therapy during the study, LDL-C, triglycerides (baricitinib 4 mg only) and apolipoprotein B decreased to pre baricitinib levels; HDL-C and apolipoprotein A-I levels remained elevated. CONCLUSIONS: Baricitinib was associated with increased LDL-C, HDL-C and triglyceride levels, but did not alter the LDL-C:HDL-C ratio. Evaluation of cardiovascular event rates during long-term treatment is warranted to further characterise these findings and their possible clinical implications.

PMID- 29463525 TI - Maternal thyroid function and child educational attainment: prospective cohort study. AB - OBJECTIVE: To determine if first trimester maternal thyroid dysfunction is a critical determinant of child scholastic performance and overall educational attainment. DESIGN: Prospective cohort study. SETTING: Avon Longitudinal Study of Parents and Children cohort in the UK. PARTICIPANTS: 4615 mother-child pairs with an available first trimester sample (median 10 weeks gestation, interquartile range 8-12). EXPOSURES: Free thyroxine, thyroid stimulating hormone, and thyroid peroxidase antibodies assessed as continuous measures and the seven clinical categories of maternal thyroid function. MAIN OUTCOME MEASURES: Five age-specific national curriculum assessments in 3580 children at entry stage assessment at 54 months, increasing up to 4461 children at their final school assessment at age 15. RESULTS: No strong evidence of clinically meaningful associations of first trimester free thyroxine and thyroid stimulating hormone levels with entry stage assessment score or Standard Assessment Test scores at any of the key stages was found. Associations of maternal free thyroxine or thyroid stimulating hormone with the total number of General Certificates of Secondary Education (GCSEs) passed (range 0-16) were all close to the null: free thyroxine, rate ratio per pmol/L 1.00 (95% confidence interval 1.00 to 1.01); and thyroid stimulating hormone, rate ratio 0.98 (0.94 to 1.02). No important relationship was observed when more detailed capped scores of GCSEs allowing for both the number and grade of pass or when language, mathematics, and science performance were examined individually or when all educational assessments undertaken by an individual from school entry to leaving were considered. 200 (4.3%) mothers were newly identified as having hypothyroidism or subclinical hypothyroidism and 97 (2.1%) subclinical hyperthyroidism or hyperthyroidism. Children of mothers with thyroid dysfunction attained an equivalent number of GCSEs and equivalent grades as children of mothers with euthyroidism. CONCLUSIONS: Maternal thyroid dysfunction in early pregnancy does not have a clinically important association with impaired child performance at school or educational achievement. PMID- 29463526 TI - Elevated Plasma Moxifloxacin Concentrations and SLCO1B1 g.-11187G>A Polymorphism in Adults with Pulmonary Tuberculosis. AB - Moxifloxacin exhibits concentration-dependent prolongation of human QTc intervals and bactericidal activity against Mycobacterium tuberculosis However, moxifloxacin plasma concentrations are variable between patients. We evaluated whether human gene polymorphisms affect moxifloxacin plasma concentrations in tuberculosis patients from two geographic regions. We enrolled a convenience sample of 49 adults with drug-sensitive pulmonary tuberculosis from Africa and the United States enrolled in two treatment trials of moxifloxacin as part of multidrug therapy. Pharmacokinetic parameters were evaluated by noncompartmental techniques. Human single-nucleotide polymorphisms of transporter genes were evaluated by analysis of covariance (ANCOVA) on moxifloxacin exposure and the peak (maximum) concentration (Cmax). The moxifloxacin area under the concentration-time curve from 0 to 24 h (AUC0-24) and Cmax were significantly increased by the drug milligram-per-kilogram dosage and the genotype of variant g.-11187G>A in the SLCO1B1 gene (rs4149015) but not by geographic region. The median moxifloxacin AUC0-24 was 46% higher and the median Cmax was 30% higher in 4 (8%) participants who had the SLCO1B1 g.-11187 AG genotype than in 45 participants who had the wild-type GG genotype (median AUC0-24 from the model, 34.4 versus 23.6 MUg . h/ml [P = 0.005, ANCOVA]; median Cmax from the model, 3.5 versus 2.7 MUg/ml [P = 0.009, ANCOVA]). Because moxifloxacin exhibits concentration-dependent prolongation of human QTc intervals and prolonged QTc intervals are associated with cardiac arrhythmia, further study is needed to evaluate the risk associated with the SLCO1B1 g.-11187G>A variant.

AB - The lack of a quantifiable marker for echinocandin activity hinders in vitro pharmacokinetic/pharmacodynamic (PK/PD) studies for Aspergillus spp. We developed an in vitro PK/PD model simulating the pharmacokinetics of anidulafungin and assessing its pharmacodynamics against Aspergillus fumigatus with a new, easily quantifiable, sensitive, and reproducible marker. Two clinical A. fumigatus isolates previously used in animals (AZN8196 and V52-35) with identical anidulafungin EUCAST (0.03 MUg/ml) and CLSI (0.015 MUg/ml) minimal effective concentrations (MEC) and one isolate (strain AFU79728) with an MEC of >16 MUg/ml were tested in a two-compartment PK/PD dialysis/diffusion closed model containing a dialysis membrane (DM) tube inoculated with 103 CFU/ml. During anidulafungin exposure, two types of fungal forms were observed inside the DM tube: floating conidia that were quantified by cultures and aberrant mycelia that were quantified by the vertical height of the mycelia attached on the DM tube. No aberrant mycelia were found for the resistant isolate or in the drug-free controls. An in vitro exposure-effect relationship was similar to that found in animals using survival as an endpoint, with a free-drug area under the concentration-time curve from 0 to 24 h (fAUC0-24) associated with 50% of maximal activity of 2.21 (range, 1.81 to 2.71) mg . h/liter in vitro versus 2.62 (range, 1.88 to 3.65) mg . h/liter in vivo (P = 0.41). The hillslopes were also similar, with 1.96 versus 1.34 (P = 0.29). Analysis of each isolate separately showed increased antifungal susceptibility between AZN8196 and V52-35 (P < 0.001) even though they have the same CLSI and EUCAST MECs, but the strains have two 2-fold dilutions lower MICs using Etest and the XTT {2,3-bis (2-methoxy-4-nitro-5 sulfophenyl)-5-[(phenylamino) carbonyl]-2H-tetrazolium hydroxide} method. Dose fractionation studies with all three echinocandins showed that their activities are best described by fAUC and not the maximum concentration of free drug (fCmax). The new marker correlated with in vivo outcome and can be used for in vitro PK/PD studies exploring the pharmacodynamics of echinocandins against Aspergillus spp. PMID- 29463528 TI - Optimization and Evaluation of Piperacillin-Tobramycin Combination Dosage Regimens against Pseudomonas aeruginosa for Patients with Altered Pharmacokinetics via the Hollow-Fiber Infection Model and Mechanism-Based Modeling. AB - Augmented renal clearance (ARC) in critically ill patients can result in suboptimal drug exposures and treatment failure. Combination dosage regimens accounting for ARC have never been optimized and evaluated against Pseudomonas aeruginosa by use of the hollow-fiber infection model (HFIM). Using a P. aeruginosa isolate from a critically ill patient and static-concentration time kill experiments (SCTKs), we studied clinically relevant piperacillin and tobramycin concentrations, alone and in combinations, against two inocula (105.8 and 107.6 CFU/ml) over 72 h. We subsequently evaluated the effects of optimized piperacillin (4 g every 4 h [q4h], given as 0.5-h infusions) plus tobramycin (5 mg/kg of body weight q24h, 7 mg/kg q24h, or 10 mg/kg q48h, given as 0.5-h infusions) regimens on killing and regrowth in the HFIM, simulating a creatinine clearance of 250 ml/min. Mechanism-based modeling was performed in S-ADAPT. In SCTKs, piperacillin plus tobramycin (except combinations with 8 mg/liter tobramycin and against the low inoculum) achieved synergistic killing (>=2 log10 versus the most active monotherapy at 48 h and 72 h) and prevented regrowth. Piperacillin monotherapy (4 g q4h) in the HFIM provided 2.4-log10 initial killing followed by regrowth at 24 h and resistance emergence. Tobramycin monotherapies displayed rapid initial killing (>=5 log10 at 13 h) followed by extensive regrowth. As predicted by mechanism-based modeling, the piperacillin plus tobramycin dosage regimens were synergistic and provided >=5-log10 killing with resistance suppression over 8 days in the HFIM. Optimized piperacillin-tobramycin regimens provided significant bacterial killing and suppressed resistance emergence. These regimens appear to be highly promising for effective and early treatment, even in the near-worst-case scenario of ARC.

AB - Some Kelch mutations of the Plasmodium falciparum K13 protein confer increased survival to dihydroartemisinin (DHA)-treated ring-stage parasites. Here, we asked if K13 mutations affect a dormancy phenotype allowing parasites to survive DHA exposure and then sorbitol selection. Although recrudescence from dormancy differed between two distinct parasite lines, it was similar for isogenic lines carrying single-site substitutions in K13. Therefore, K13 mutations do not alter the DHA-sorbitol combined dormancy phenotype; rather, traits from other loci likely determine this phenotype. PMID- 29463529 TI - Complete Genome Sequencing of Acinetobacter baumannii Strain K50 Discloses the Large Conjugative Plasmid pK50a Encoding Carbapenemase OXA-23 and Extended Spectrum beta-Lactamase GES-11. AB - Multidrug-resistant (MDR) Acinetobacter baumannii strains appeared as serious emerging nosocomial pathogens in clinical environments and especially in intensive care units (ICUs). A. baumannii strain K50, recovered from a hospitalized patient in Kuwait, exhibited resistance to carbapenems and additionally to ciprofloxacin, chloramphenicol, sulfonamides, amikacin, and gentamicin. Genome sequencing revealed that the strain possesses two plasmids, pK50a (79.6 kb) and pK50b (9.5 kb), and a 3.75-Mb chromosome. A. baumannii K50 exhibits an average nucleotide identity (ANI) of 99.98% to the previously reported Iraqi clinical isolate AA-014, even though the latter strain lacked plasmid pK50a. Strain K50 belongs to sequence type 158 (ST158) (Pasteur scheme) and ST499 (Oxford scheme). Plasmid pK50a is a member of the Aci6 (replication group 6 [RG6]) group of Acinetobacter plasmids and carries a conjugative transfer module and two antibiotic resistance gene regions. The transposon Tn2008 carries the carbapenemase gene blaOXA-23, whereas a class 1 integron harbors the resistance genes blaGES-11, aacA4, dfrA7, qacEDelta1, and sul1, conferring resistance to all beta-lactams and reduced susceptibility to carbapenems and resistance to aminoglycosides, trimethoprim, quaternary ammonium compounds, and sulfamethoxazole, respectively. The class 1 integron is flanked by MITEs (miniature inverted-repeat transposable elements) delimiting the element at its insertion site.

AB - A novel 61,578-bp genomic island named Proteus genomic island 2 (PGI2) was characterized in Proteus mirabilis of swine origin in China. The 23.85-kb backbone of PGI2 is related to those of Salmonella genomic island 1 and Acinetobacter genomic island 1. The multidrug resistance (MDR) region of PGI2 is a complex class 1 integron containing 14 different resistance genes. PGI2 was conjugally mobilized in trans to Escherichia coli in the presence of a conjugative IncC helper plasmid. PMID- 29463533 TI - Complex Interplay between Sphingolipid and Sterol Metabolism Revealed by Perturbations to the Leishmania Metabolome Caused by Miltefosine. AB - With the World Health Organization reporting over 30,000 deaths and 200,000 to 400,000 new cases annually, visceral leishmaniasis is a serious disease affecting some of the world's poorest people. As drug resistance continues to rise, there is a huge unmet need to improve treatment. Miltefosine remains one of the main treatments for leishmaniasis, yet its mode of action (MoA) is still unknown. Understanding the MoA of this drug and parasite response to treatment could help pave the way for new and more successful treatments for leishmaniasis. A novel method has been devised to study the metabolome and lipidome of Leishmania donovani axenic amastigotes treated with miltefosine. Miltefosine caused a dramatic decrease in many membrane phospholipids (PLs), in addition to amino acid pools, while sphingolipids (SLs) and sterols increased. Leishmania major promastigotes devoid of SL biosynthesis through loss of the serine palmitoyl transferase gene (DeltaLCB2) were 3-fold less sensitive to miltefosine than wild type (WT) parasites. Changes in the metabolome and lipidome of miltefosine treated L. major mirrored those of L. donovani A lack of SLs in the DeltaLCB2 mutant was matched by substantial alterations in sterol content. Together, these data indicate that SLs and ergosterol are important for miltefosine sensitivity and, perhaps, MoA. PMID- 29463534 TI - Alginate Oligosaccharide-Induced Modification of the lasI-lasR and rhlI-rhlR Quorum-Sensing Systems in Pseudomonas aeruginosa. AB - Pseudomonas aeruginosa plays a major role in many chronic infections. Its ability to readily form biofilms contributes to its success as an opportunistic pathogen and its resistance/tolerance to antimicrobial/antibiotic therapy. A low-molecular weight alginate oligomer (OligoG CF-5/20) derived from marine algae has previously been shown to impair motility in P. aeruginosa biofilms and disrupt pseudomonal biofilm assembly. As these bacterial phenotypes are regulated by quorum sensing (QS), we hypothesized that OligoG CF-5/20 may induce alterations in QS signaling in P. aeruginosa QS regulation was studied by using Chromobacterium violaceum CV026 biosensor assays that showed a significant reduction in acyl homoserine lactone (AHL) production following OligoG CF-5/20 treatment (>=2%; P < 0.05). This effect was confirmed by liquid chromatography mass spectrometry analysis of C4-AHL and 3-oxo-C12-AHL production (>=2%; P < 0.05). Moreover, quantitative PCR showed that reduced expression of both the las and rhl systems was induced following 24 h of treatment with OligoG CF-5/20 (>=0.2%; P < 0.05). Circular dichroism spectroscopy indicated that these alterations were not due to steric interaction between the AHL and OligoG CF 5/20. Confocal laser scanning microscopy (CLSM) and COMSTAT image analysis demonstrated that OligoG CF-5/20-treated biofilms had a dose-dependent decrease in biomass that was associated with inhibition of extracellular DNA synthesis (>=0.5%; P < 0.05). These changes correlated with alterations in the extracellular production of the pseudomonal virulence factors pyocyanin, rhamnolipids, elastase, and total protease (P < 0.05). The ability of OligoG CF 5/20 to modify QS signaling in P. aeruginosa PAO1 may influence critical downstream functions such as virulence factor production and biofilm formation. PMID- 29463535 TI - GRL-079, a Novel HIV-1 Protease Inhibitor, Is Extremely Potent against Multidrug Resistant HIV-1 Variants and Has a High Genetic Barrier against the Emergence of Resistant Variants. AB - We identified four novel nonpeptidic human immunodeficiency virus type 1 (HIV-1) protease inhibitors (PIs), GRL-078, -079, -077, and -058, containing an alkylamine at the C-5 position of P2 tetrahydropyrano-tetrahydrofuran (Tp-THF) and a P2' cyclopropyl (Cp) (or isopropyl)-aminobenzothiazole (Abt) moiety. Their 50% effective concentrations (EC50s) were 2.5 to 30 nM against wild-type HIV-1NL4 3, 0.3 to 6.7 nM against HIV-2EHO, and 0.9 to 90 nM against laboratory-selected PI-resistant HIV-1 and clinical HIV-1 variants resistant to multiple FDA-approved PIs (HIVMDR). GRL-078, -079, -077, and -058 also effectively blocked the replication of HIV-1 variants highly resistant to darunavir (DRV) (HIVDRVrp51), with EC50s of 38, 62, 61, and 90 nM, respectively, while four FDA-approved PIs examined (amprenavir, atazanavir, lopinavir [LPV], and DRV) had virtually no activity (EC50s of >1,000 nM) against HIVDRVrp51 Structurally, GRL-078, -079, and -058 form strong hydrogen bond interactions between Tp-THF modified at C-5 and Asp29/Asp30/Gly48 of wild-type protease, while the P2' Cp-Abt group forms strong hydrogen bonds with Asp30'. The Tp-THF and Cp-Abt moieties also have good nonpolar interactions with protease residues located in the flap region. For selection with LPV and DRV by use of a mixture of 11 HIVMDR strains (HIV11MIX), HIV11MIX became highly resistant to LPV and DRV over 13 to 32 and 32 to 41 weeks, respectively. However, for selection with GRL-079 and GRL-058, HIV11MIX failed to replicate at >0.08 MUM and >0.2 MUM, respectively. Thermal stability results supported the highly favorable anti-HIV-1 potency of GRL-079 as well as other PIs. The present data strongly suggest that the P2 Tp-THF group modified at C-5 and the P2' Abt group contribute to the potent anti-HIV-1 profiles of the four PIs against HIV-1NL4-3 and a wide spectrum of HIVMDR strains.

AB - Next-generation sequencing of 6 mcr-1-harboring Escherichia coli and Klebsiella pneumoniae isolates collected from a tertiary care hospital in China revealed significant sequence variations in the regions flanking the mcr-1 gene. While sequence variations significantly affected the expression and promoter activity of mcr-1, the mcr-1 gene expression levels did not correlate with the in vitro colistin resistance levels, which warrants further in-depth investigations. PMID- 29463537 TI - Impact of Oral Fidaxomicin Administration on the Intestinal Microbiota and Susceptibility to Clostridium difficile Colonization in Mice. AB - Clostridium difficile infection (CDI), a common cause of hospital-acquired infections, typically occurs after disruption of the normal gut microbiome by broad-spectrum antibiotics. Fidaxomicin is a narrow-spectrum antibiotic that demonstrates a reduced impact on the normal gut microbiota and is approved for the treatment of CDI. To further explore the benefits of this property, we used a murine model to examine the effects of fidaxomicin versus vancomycin on gut microbiota and susceptibility to C. difficile colonization while tracking microbiota recovery over time. Mice were exposed to fidaxomicin or vancomycin by oral gavage for 3 days and subsequently challenged with C. difficile spores at predetermined time points up to 21 days postexposure to antibiotics. Fecal samples were subsequently collected for analysis. Twenty-four hours postchallenge, mice were euthanized and the colon contents harvested. The microbiota was characterized using 16S rRNA gene sequencing. All fidaxomicin exposed mice (except for one at day 8) were resistant to C. difficile colonization. However, 9 of 15 vancomycin-exposed mice were susceptible to C. difficile colonization until day 12. All vancomycin-exposed mice recovered colonization resistance by day 16. Bacterial diversity was similar prior to antibiotic exposure in both arms and decreased substantially after exposure. A shift in taxonomic structure and composition occurred after both exposures; however, the shift was greater in vancomycin-exposed than in fidaxomicin-exposed mice. In summary, compared with vancomycin, fidaxomicin exposure had less impact on microbiota composition, promoted faster microbial recovery, and had less impact on the loss of C. difficile colonization resistance.

AB - The molecular mechanisms of tolerance and persistence associated with several compounds in Acinetobacter baumannii clinical isolates are unknown. Using transcriptomic and phenotypic studies, we found a link between mechanisms of bacterial tolerance to chlorhexidine and the development of persistence in the presence of imipenem in an A. baumannii strain belonging to clinical clone ST-2 (OXA-24 beta-lactamase and AbkAB toxin-antitoxin [TA] system carried in a plasmid). Interestingly, the strain A. baumannii ATCC 17978 (AbkAB TA system from plasmid) showed persistence in the presence of imipenem and chlorhexidine. PMID- 29463539 TI - Pharmacokinetics of Second-Line Antituberculosis Drugs in Children with Multidrug Resistant Tuberculosis in India. AB - We studied the pharmacokinetics of levofloxacin (LFX), pyrazinamide (PZA), ethionamide (ETH), and cycloserine (CS) in children with multidrug-resistant tuberculosis (MDR-TB) who were being treated according to the Revised National TB Control Programme (RNTCP) guidelines in India. This observational, pharmacokinetic study was conducted in 25 children with MDR-TB at the Sarojini Naidu Medical College, Agra, India, who were being treated with a 24-month daily regimen. Serial blood samples were collected after directly observed administration of drugs. Estimations of plasma LFX, PZA, ETH, and CS were undertaken according to validated methods by high-performance liquid chromatography. Adverse events were noted at 6 months of treatment. The peak concentration (Cmax) of LFX was significantly higher in female than male children (11.5 MUg/ml versus 7.3 MUg/ml; P = 0.017). Children below 12 years of age had significantly higher ETH exposure (area under the concentration-time curve from 0 to 8 h [AUC0-8]) than those above 12 years of age (17.5 MUg/ml . h versus 9.4 MUg/ml; P = 0.030). Multiple linear regression analysis showed significant influence of gender on Cmax of ETH and age on Cmax and AUC0-8 of CS. This is the first and only study from India reporting on the pharmacokinetics of LFX, ETH, PZA, and CS in children with MDR-TB treated in the Government of India program. More studies on the safety and pharmacokinetics of second-line anti-TB drugs in children with MDR-TB from different settings are required. PMID- 29463540 TI - Pharmacokinetics of Penicillin G in Preterm and Term Neonates. AB - Group B streptococci are common causative agents of early-onset neonatal sepsis (EOS). Pharmacokinetic (PK) data for penicillin G have been described for extremely preterm neonates but have been poorly described for late-preterm and term neonates. Thus, evidence-based dosing recommendations are lacking. We describe the PK of penicillin G in neonates with a gestational age (GA) of >=32 weeks and a postnatal age of <72 h. Penicillin G was administered intravenously at a dose of 25,000 or 50,000 IU/kg of body weight every 12 h (q12h). At steady state, PK blood samples were collected prior to and at 5 min, 1 h, 3 h, 8 h, and 12 h after injection. Noncompartmental PK analysis was performed with WinNonlin software. With those data in combination with data from neonates with a GA of <=28 weeks, we developed a population PK model using NONMEM software and performed probability of target attainment (PTA) simulations. In total, 16 neonates with a GA of >=32 weeks were included in noncompartmental analysis. The median volume of distribution (V) was 0.50 liters/kg (interquartile range, 0.42 to 0.57 liters/kg), the median clearance (CL) was 0.21 liters/h (interquartile range, 0.16 to 0.29 liters/kg), and the median half-life was 3.6 h (interquartile range, 3.2 to 4.3 h). In the population PK analysis that included 35 neonates, a two-compartment model best described the data. The final parameter estimates were 10.3 liters/70 kg and 29.8 liters/70 kg for V of the central and peripheral compartments, respectively, and 13.2 liters/h/70 kg for CL. Considering the fraction of unbound penicillin G to be 40%, the PTA of an unbound drug concentration that exceeds the MIC for 40% of the dosing interval was >90% for MICs of <=2 mg/liter with doses of 25,000 IU/kg q12h. In neonates, regardless of GA, the PK parameters of penicillin G were similar. The dose of 25,000 IU/kg q12h is suggested for treatment of group B streptococcal EOS diagnosed within the first 72 h of life.

AB - Mycobacterium tuberculosis kills more people than any other bacterial pathogen and is becoming increasingly untreatable due to the emergence of resistance. Verapamil, an FDA-approved calcium channel blocker, potentiates the effect of several antituberculosis (anti-TB) drugs in vitro and in vivo This potentiation is widely attributed to inhibition of the efflux pumps of M. tuberculosis, resulting in intrabacterial drug accumulation. Here, we confirmed and quantified verapamil's synergy with several anti-TB drugs, including bedaquiline (BDQ) and clofazimine (CFZ), but found that the effect is not due to increased intrabacterial drug accumulation. We show that, consistent with its in vitro potentiating effects on anti-TB drugs that target or require oxidative phosphorylation, the cationic amphiphile verapamil disrupts membrane function and induces a membrane stress response similar to those seen with other membrane active agents. We recapitulated these activities in vitro using inverted mycobacterial membrane vesicles, indicating a direct effect of verapamil on membrane energetics. We observed bactericidal activity against nonreplicating "persister" M. tuberculosis that was consistent with such a mechanism of action. In addition, we demonstrated a pharmacokinetic interaction whereby human equivalent doses of verapamil caused a boost of rifampin exposure in mice, providing a potential explanation for the observed treatment-shortening effect of verapamil in mice receiving first-line drugs. Our findings thus elucidate the mechanistic basis for verapamil's potentiation of anti-TB drugs in vitro and in vivo and highlight a previously unrecognized role for the membrane of M. tuberculosis as a pharmacologic target. PMID- 29463542 TI - Population Pharmacokinetic Properties of Sulfadoxine and Pyrimethamine: a Pooled Analysis To Inform Optimal Dosing in African Children with Uncomplicated Malaria. AB - Sulfadoxine-pyrimethamine with amodiaquine is recommended by the World Health Organization as seasonal malaria chemoprevention for children aged 3 to 59 months in the sub-Sahel regions of Africa. Suboptimal dosing in children may lead to treatment failure and increased resistance. Pooled individual patient data from four previously published trials on the pharmacokinetics of sulfadoxine and pyrimethamine in 415 pediatric and 386 adult patients were analyzed using nonlinear mixed-effects modeling to evaluate the current dosing regimen and, if needed, to propose an optimized dosing regimen for children under 5 years of age. The population pharmacokinetics of sulfadoxine and pyrimethamine were both best described by a one-compartment disposition model with first-order absorption and elimination. Body weight, age, and nutritional status (measured as the weight-for age Z-score) were found to be significant covariates. Allometric scaling with total body weight and the maturation of clearance in children by postgestational age improved the model fit. Underweight-for-age children were found to have 15.3% and 26.7% lower bioavailabilities of sulfadoxine and pyrimethamine, respectively, for each Z-score unit below -2. Under current dosing recommendations, simulation predicted that the median day 7 concentration was below the 25th percentile for a typical adult patient (50 kg) for sulfadoxine for patients in the weight bands of 8 to 9, 19 to 24, 46 to 49, and 74 to 79 kg and for pyrimethamine for patients in the weight bands of 8 to 9, 14 to 24, and 42 to 49 kg. An evidence-based dosing regimen was constructed that would achieve sulfadoxine and pyrimethamine exposures in young children and underweight-for-age young children that were similar to those currently seen in a typical adult. PMID- 29463543 TI - Mesoscopic Energy Minimization Drives Pseudomonas aeruginosa Biofilm Morphologies and Consequent Stratification of Antibiotic Activity Based on Cell Metabolism. AB - Segregation of bacteria based on their metabolic activities in biofilms plays an important role in the development of antibiotic resistance. Mushroom-shaped biofilm structures, which are reported for many bacteria, exhibit topographically varying levels of multiple drug resistance from the cap of the mushroom to its stalk. Understanding the dynamics behind the formation of such structures can aid in design of drug delivery systems, antibiotics, or physical systems for removal of biofilms. We explored the development of metabolically heterogeneous Pseudomonas aeruginosa biofilms using numerical models and laboratory knockout experiments on wild-type and chemotaxis-deficient mutants. We show that chemotactic processes dominate the transformation of slender and hemispherical structures into mushroom structures with a signature cap. Cellular Potts model simulation and experimental data provide evidence that accelerated movement of bacteria along the periphery of the biofilm, due to nutrient cues, results in the formation of mushroom structures and bacterial segregation. Multidrug resistance of bacteria is one of the most threatening dangers to public health. Understanding the mechanisms of the development of mushroom-shaped biofilms helps to identify the multidrug-resistant regions. We decoded the dynamics of the structural evolution of bacterial biofilms and the physics behind the formation of biofilm structures as well as the biological triggers that produce them. Combining in vitro gene knockout experiments with in silico models showed that chemotactic motility is one of the main driving forces for the formation of stalks and caps. Our results provide physicists and biologists with a new perspective on biofilm removal and eradication strategies. PMID- 29463544 TI - Gene Expression of Pneumocystis murina after Treatment with Anidulafungin Results in Strong Signals for Sexual Reproduction, Cell Wall Integrity, and Cell Cycle Arrest, Indicating a Requirement for Ascus Formation for Proliferation. AB - The echinocandins are a class of antifungal agents that target beta-1,3-d-glucan (BG) biosynthesis. In the ascigerous Pneumocystis species, treatment with these drugs depletes the ascus life cycle stage, which contains BG, but large numbers of forms which do not express BG remain in the infected lungs. In the present study, the gene expression profiles of Pneumocystis murina were compared between infected, untreated mice and mice treated with anidulafungin for 2 weeks to understand the metabolism of the persisting forms. Almost 80 genes were significantly up- or downregulated. Like other fungi exposed to echinocandins, genes associated with sexual replication, cell wall integrity, cell cycle arrest, and stress comprised the strongest upregulated signals in P. murina from the treated mice. The upregulation of the P. murina beta-1,3-d-glucan endohydrolase and endo-1,3-glucanase was notable and may explain the disappearance of the existing asci in the lungs of treated mice since both enzymes can degrade BG. The biochemical measurement of BG in the lungs of treated mice and fluorescence microscopy with an anti-BG antibody supported the loss of BG. Downregulated signals included genes involved in cell replication, genome stability, and ribosomal biogenesis and function and the Pneumocystis-specific genes encoding the major surface glycoproteins (Msg). These studies suggest that P. murina attempted to undergo sexual replication in response to a stressed environment and was halted in any type of proliferative cycle, likely due to a lack of BG. Asci appear to be a required part of the life cycle stage of Pneumocystis, and BG may be needed to facilitate progression through the life cycle via sexual replication.

AB - The emergence of azole-resistant Aspergillus fumigatus has become a clinical problem in many parts of the world. Several amino acid mutations in the azole target protein Cyp51Ap contribute to this resistance, with the most concerning being the environmentally derived TR34/L98H and TR46/Y121F/T289A mutations. Here, we performed passive surveillance to assess a sample of the A. fumigatus population in the United States for the presence of these mutations. We found 1.4% of those isolates to exhibit elevated MIC via broth microdilution, and five of those isolates harbored the TR34/L98H mutation.

PMID- 29463548 TI - Determinants of hematology-oncology trainees' postfellowship career pathways with a focus on nonmalignant hematology. AB - Nonmalignant hematologic conditions are extremely prevalent and contribute significantly to the global burden of disease. The US health care system may soon face a shortage of specialists in nonmalignant hematology. We sought to identify factors that lead hematology-oncology fellows to pursue (or not to pursue) careers in nonmalignant hematology. Cross-sectional, web-based survey distributed to 149 graduates of a hematology-oncology fellowship program at a large academic medical center between 1998 and 2016. Eighty-six out of 149 graduates responded (57.7%); most (59 [68.6%]) practice at an academic medical center. Respondents spend a mean of 61% of their time in clinical practice, 23.7% conducting research, 5.2% in education, and 5.2% in administration. Those in clinical practice spend a mean of 52.1% of their time in solid tumor oncology, 37.5% in hematologic malignancies, and 10% in nonmalignant hematology; only 1 spent >50% of time practicing nonmalignant hematology. Factors most significantly affecting choice of patient population included clinical experience during fellowship and intellectual stimulation of the patient population/disease type. Factors that could have most significantly influenced a decision to spend more time in nonmalignant hematology included increased exposure/access to role models and mentors and opportunities for better career growth/advancement. Fellowship graduates spend >50% of their time in clinical practice, but almost none spend a significant amount of time practicing nonmalignant hematology. Given the growing number of patients with nonmalignant hematologic conditions and a possible future provider shortage, medical trainees should be encouraged to pursue careers in nonmalignant hematology. PMID- 29463546 TI - Treatment with Atorvastatin Provides Additional Benefits to Imipenem in a Model of Gram-Negative Pneumonia Induced by Klebsiella pneumoniae in Mice. AB - The clinical pathogen Klebsiella pneumoniae is a relevant cause of nosocomial infections, and resistance to current treatment with carbapenem antibiotics is becoming a significant problem. Statins are inhibitors of 3-hydroxy-3 methylglutaryl coenzyme A (HMG-CoA) used for controlling plasma cholesterol levels. There is clinical evidence showing other effects of statins, including decrease of lung inflammation. In the current study, we show that pretreatment with atorvastatin markedly attenuated lung injury, which was correlated with a reduction in the cellular influx into the alveolar space and lungs and downmodulation of the production of proinflammatory mediators in the initial phase of infection in C57BL/6 mice with K. pneumoniae However, atorvastatin did not alter the number of bacteria in the lungs and blood of infected mice, despite decreasing local inflammatory response. Interestingly, mice that received combined treatment with atorvastatin and imipenem displayed better survival than mice treated with vehicle, atorvastatin, or imipenem alone. These findings suggest that atorvastatin could be an adjuvant in host-directed therapies for multidrug-resistant K. pneumoniae, based on its powerful pleiotropic immunomodulatory effects. Together with antimicrobial approaches, combination therapy with anti-inflammatory compounds could improve the efficiency of therapy during acute lung infections.

AB - Purpose: WST11 vascular targeted photodynamic therapy (VTP) is a local ablation approach relying upon rapid, free radical-mediated destruction of tumor vasculature. A phase III trial showed that VTP significantly reduced disease progression when compared with active surveillance in patients with low-risk prostate cancer. The aim of this study was to identify a druggable pathway that could be combined with VTP to improve its efficacy and applicability to higher risk prostate cancer tumors.Experimental Design: Transcriptome analysis of VTP treated tumors (LNCaP-AR xenografts) was used to identify a candidate pathway for combination therapy. The efficacy of the combination therapy was assessed in mice bearing LNCaP-AR or VCaP tumors.Results: Gene set enrichment analysis identifies the enrichment of androgen-responsive gene sets within hours after VTP treatment, suggesting that the androgen receptor (AR) may be a viable target in combination with VTP. We tested this hypothesis in mice bearing LNCaP-AR xenograft tumors by using androgen deprivation therapy (ADT), degarelix, in combination with VTP. Compared with either ADT or VTP alone, a single dose of degarelix in concert with VTP significantly inhibited tumor growth. A sharp decline in serum prostate specific antigen (PSA) confirmed AR inhibition in this group. Tumors treated by VTP and degarelix displayed intense terminal deoxynucleotidyl transferase mediated dUTP nick end labeling staining 7 days after treatment, supporting an increased apoptotic frequency underlying the effect on tumor inhibition.Conclusions: Improvement of local tumor control following androgen deprivation combined with VTP provides the rationale and preliminary protocol parameters for clinical trials in patients presented with locally advanced prostate cancer.

AB - Purpose: This open-label, multicenter, dose-finding, phase Ib study (NCT01546038) evaluated the safety, pharmacokinetics, pharmacodynamics, and clinical activity of the novel Hedgehog pathway Smoothened inhibitor glasdegib (PF-04449913) in patients (N = 52) with acute myeloid leukemia (AML) or high-risk myelodysplastic syndrome (MDS).Experimental Design: Glasdegib 100 or 200 mg was administered orally, once daily in 28-day cycles, in combination with low-dose cytarabine (arm A) or decitabine (arm B) to newly diagnosed patients considered not suitable for standard induction chemotherapy, and in combination with cytarabine/daunorubicin (arm C) to fit patients. The study followed a standard 3+3 dose-escalation design. The primary endpoint was dose-limiting toxicity (DLT). Ten additional patients were enrolled in expansion cohorts of arms A (n = 23) and C (n = 22) to confirm the recommended phase II dose (RP2D).Results: No DLTs were observed in arms A and B; 1 DLT (grade 4 neuropathy) occurred in arm C. The most common treatment-related nonhematologic adverse events were mostly grades 1 and 2 in all arms. Muscle spasms, dysgeusia, and alopecia were generally mild. Overall, 16 patients (31%) achieved a complete remission (CR)/CR with incomplete blood count recovery. Note that 100 mg daily was selected as the RP2D for glasdegib in combination with standard chemotherapies in the absence of an estimated MTD in this setting.Conclusions: Treatment with glasdegib in combination with standard chemotherapy was generally well-tolerated and consistent with prior findings, warranting further evaluation of glasdegib-based combinations in patients with AML or high-risk MDS.

AB - Purpose: Optimal dosing is critical for immunocytokine-based cancer immunotherapy to maximize efficacy and minimize toxicity. Cergutuzumab amunaleukin (CEA-IL2v) is a novel CEA-targeted immunocytokine. We set out to develop a mathematical model to predict intratumoral CEA-IL2v concentrations following various systemic dosing intensities.Experimental Design: Sequential measurements of CEA-IL2v plasma concentrations in 74 patients with solid tumors were applied in a series of differential equations to devise a model that also incorporates the peripheral concentrations of IL2 receptor-positive cell populations (i.e., CD8+, CD4+, NK, and B cells), which affect tumor bioavailability of CEA-IL2v. Imaging data from a subset of 14 patients were subsequently utilized to additionally predict antibody uptake in tumor tissues.Results: We created a pharmacokinetic/pharmacodynamic mathematical model that incorporates the expansion of IL2R-positive target cells at multiple dose levels and different schedules of CEA-IL2v. Model-based prediction of drug levels correlated with the concentration of IL2R-positive cells in the peripheral blood of patients. The pharmacokinetic model was further refined and extended by adding a model of antibody uptake, which is based on drug dose and the biological properties of the tumor. In silico predictions of our model correlated with imaging data and demonstrated that a dose-dense schedule comprising escalating doses and shortened intervals of drug administration can improve intratumoral drug uptake and overcome consumption of CEA-IL2v by the expanding population of IL2R-positive cells.Conclusions: The model presented here allows simulation of individualized treatment plans for optimal dosing and scheduling of immunocytokines for anticancer immunotherapy.

PMID- 29463552 TI - Integrated Pharmacokinetic/Pharmacodynamic Model of a Bispecific CD3xCD123 DART Molecule in Nonhuman Primates: Evaluation of Activity and Impact of Immunogenicity. AB - Purpose: Flotetuzumab (MGD006 or S80880) is a bispecific molecule that recognizes CD3 and CD123 membrane proteins, redirecting T cells to kill CD123-expressing cells for the treatment of acute myeloid leukemia. In this study, we developed a mathematical model to characterize MGD006 exposure-response relationships and to assess the impact of its immunogenicity in cynomolgus monkeys.Experimental Design: Thirty-two animals received multiple escalating doses (100-300-600-1,000 ng/kg/day) via intravenous infusion continuously 4 days a week. The model reflects sequential binding of MGD006 to CD3 and CD123 receptors. Formation of the MGD006/CD3 complex was connected to total T cells undergoing trafficking, whereas the formation of the trimolecular complex results in T-cell activation and clonal expansion. Activated T cells were used to drive the peripheral depletion of CD123-positive cells. Anti-drug antibody development was linked to MGD006 disposition as an elimination pathway. Model validation was tested by predicting the activity of MGD006 in eight monkeys receiving continuous 7-day infusions.Results: MGD006 disposition and total T-cell and CD123-positive cell profiles were well characterized. Anti-drug antibody development led to the suppression of T-cell trafficking but did not systematically abolish CD123 positive cell depletion. Target cell depletion could persist after drug elimination owing to the self-proliferation of activated T cells generated during the first cycles. The model was externally validated with the 7-day infusion dosing schedule.Conclusions: A translational model was developed for MGD006 that features T-cell activation and expansion as a key driver of pharmacologic activity and provides a mechanistic quantitative platform to inform dosing strategies in ongoing clinical studies.

PMID- 29463553 TI - Concurrent Inhibition of Neurosphere and Monolayer Cells of Pediatric Glioblastoma by Aurora A Inhibitor MLN8237 Predicted Survival Extension in PDOX Models. AB - Purpose: Pediatric glioblastoma multiforme (pGBM) is a highly aggressive tumor in need of novel therapies. Our objective was to demonstrate the therapeutic efficacy of MLN8237 (alisertib), an orally available selective inhibitor of Aurora A kinase (AURKA), and to evaluate which in vitro model system (monolayer or neurosphere) can predict therapeutic efficacy in vivoExperimental Design: AURKA mRNA expressions were screened with qRT-PCR. In vitro antitumor effects were examined in three matching pairs of monolayer and neurosphere lines established from patient-derived orthotopic xenograft (PDOX) models of the untreated (IC-4687GBM), recurrent (IC-3752GBM), and terminal (IC-R0315GBM) tumors, and in vivo therapeutic efficacy through log rank analysis of survival times in two models (IC-4687GBM and IC-R0315GBM) following MLN8237 treatment (30 mg/kg/day, orally, 12 days). Drug concentrations in vivo and mechanism of action and resistance were also investigated.Results: AURKA mRNA overexpression was detected in 14 pGBM tumors, 10 PDOX models, and 6 cultured pGBM lines as compared with 11 low-grade gliomas and normal brains. MLN8237 penetrated into pGBM xenografts in mouse brains. Significant extension of survival times were achieved in IC-4687GBM of which both neurosphere and monolayer were inhibited in vitro, but not in IC-R0315GBM of which only neurosphere cells responded (similar to IC 3752GBM). Apoptosis-mediated MLN8237 induced cell death, and the presence of AURKA-negative and CD133+ cells appears to have contributed to in vivo therapy resistance.Conclusions: MLN8237 successfully targeted AURKA in a subset of pGBMs. Our data suggest that combination therapy should aim at AURKA-negative and/or CD133+ pGBM cells to prevent tumor recurrence.

AB - Purpose: The clinical utility of circulating tumor DNA (ctDNA) monitoring has been shown in tumors that harbor highly recurrent mutations. Leiomyosarcoma represents a type of tumor with a wide spectrum of heterogeneous genomic abnormalities; thus, targeting hotspot mutations or a narrow genomic region for ctDNA detection may not be practical. Here, we demonstrate a combinatorial approach that integrates different sequencing protocols for the orthogonal detection of single-nucleotide variants (SNV), small indels, and copy-number alterations (CNA) in ctDNA.Experimental Design: We employed Cancer Personalized Profiling by deep Sequencing (CAPP-Seq) for the analysis of SNVs and indels, together with a genome-wide interrogation of CNAs by Genome Representation Profiling (GRP). We profiled 28 longitudinal plasma samples and 25 tumor specimens from 7 patients with leiomyosarcoma.Results: We detected ctDNA in 6 of 7 of these patients with >98% specificity for mutant allele fractions down to a level of 0.01%. We show that results from CAPP-Seq and GRP are highly concordant, and the combination of these methods allows for more comprehensive monitoring of ctDNA by profiling a wide spectrum of tumor-specific markers. By analyzing multiple tumor specimens in individual patients obtained from different sites and at different times during treatment, we observed clonal evolution of these tumors that was reflected by ctDNA profiles.Conclusions: Our strategy allows for the comprehensive monitoring of a broad spectrum of tumor-specific markers in plasma. Our approach may be clinically useful not only in leiomyosarcoma but also in other tumor types that lack recurrent genomic alterations. Clin Cancer Res; 24(11); 2688-99. (c)2018 AACR. PMID- 29463555 TI - Foretinib Overcomes Entrectinib Resistance Associated with the NTRK1 G667C Mutation in NTRK1 Fusion-Positive Tumor Cells in a Brain Metastasis Model. AB - Purpose: Rearrangement of the neurotrophic tropomyosin receptor kinase 1 (NTRK1) gene, which encodes tyrosine receptor kinase A (TRK-A), occurs in various cancers, including colon cancer. Although entrectinib is effective in the treatment of central nervous system (CNS) metastases that express NTRK1 fusion proteins, acquired resistance inevitably results in recurrence. The CNS is a sanctuary for targeted drugs; however, the mechanism by which CNS metastases become entrectinib-resistant remains elusive and must be clarified to develop better therapeutics.Experimental Design: The entrectinib-resistant cell line KM12SM-ER was developed by continuous treatment with entrectinib in the brain metastasis-mimicking model inoculated with the entrectinib-sensitive human colon cancer cell line KM12SM, which harbors the TPM3-NTRK1 gene fusion. The mechanism of entrectinib resistance in KM12SM-ER cells was examined by next-generation sequencing. Compounds that overcame entrectinib resistance were screened from a library of 122 kinase inhibitors.Results: KM12SM-ER cells, which showed moderate resistance to entrectinib in vitro, had acquired the G667C mutation in NTRK1 The kinase inhibitor foretinib inhibited TRK-A phosphorylation and the viability of KM12SM-ER cells bearing the NTRK1-G667C mutation in vitro Moreover, foretinib markedly inhibited the progression of entrectinib-refractory KM12SM-ER-derived liver metastases and brain tumors in animal models, predominantly through inhibition of TRK-A phosphorylation.Conclusions: These results suggest that foretinib may be effective in overcoming entrectinib resistance associated with the NTRK1-G667C mutation in NTRK1 fusion-positive tumors in various organs, including the brain, and provide a rationale for clinical trials of foretinib in cancer patients with entrectinib-resistant tumors harboring the NTRK1-G667C mutation, including patients with brain metastases.

AB - Purpose: TGFbeta1 plays a critical role in inflammation and immune responses and treatment response and survival. TGFbeta1 variants may affect its expression level or functional efficiency, thus modifying tumor status and survival in human papillomavirus (HPV)-positive squamous cell carcinoma of the oropharynx (SCCOP).Experimental Design: We determined tumor HPV16 status and genotyped three TGFbeta1 polymorphisms in 564 incident SCCOP patients treated with radiotherapy or chemoradiation. Univariate and multivariable Cox models were used to evaluate the associations between the three polymorphisms and survival.Results: Overall, 85% of patients (482 of 564) had HPV16-positive SCCOP. We found that TGFbeta1 rs1982073 had statistically significant associations with survival, whereas TGFbeta1 rs1800469 and TGFbeta1 rs1800471 did not. Patients with TGFbeta1 rs1982073 CT/CC variant genotypes had significantly better overall, disease specific, and disease-free survival compared with those with the corresponding common homozygous TT genotype (all log-rank: P < 0.001). Furthermore, these genotypes were significantly associated with an approximately 5 times reduced risk of overall death, death owing to disease, and recurrence after multivariable adjustment. Moreover, the stratified analyses by tumor HPV status indicated that the significant effects of TGFbeta1 rs1982073 polymorphism on survival were found among HPV16-positive SCCOP patients only. Finally, the functional relevance of these variants was further characterized.Conclusions: Our findings support that the TGFbeta1 rs1982073 polymorphism plays a significant role in the prognosis of SCCOP, especially in HPV16-positive SCCOP patients treated with chemoradiation. Prospective studies with larger sample sizes are needed to confirm these findings. Clin Cancer Res; 24(9); 2225-33. (c)2018 AACR. PMID- 29463557 TI - The Airway Transcriptome as a Biomarker for Early Lung Cancer Detection. AB - Lung cancer remains the leading cause of cancer-related death due to its advanced stage at diagnosis. Early detection of lung cancer can be improved by better defining who should be screened radiographically and determining which imaging detected pulmonary nodules are malignant. Gene expression biomarkers measured in normal-appearing airway epithelium provide an opportunity to use lung cancer associated molecular changes in this tissue for early detection of lung cancer. Molecular changes in the airway may result from an etiologic field of injury and/or field cancerization. The etiologic field of injury reflects the aberrant physiologic response to carcinogen exposure that creates a susceptible microenvironment for cancer initiation. In contrast, field cancerization reflects effects of "first-hit" mutations in a clone of cells from which the tumor ultimately arises or the effects of the tumor on the surrounding tissue. These fields might have value both for assessing lung cancer risk and diagnosis. Cancer associated gene expression changes in the bronchial airway have recently been used to develop and validate a 23-gene classifier that improves the diagnostic yield of bronchoscopy for lung cancer among intermediate-risk patients. Recent studies have demonstrated that these lung cancer-related gene expression changes extend to nasal epithelial cells that can be sampled noninvasively. While the bronchial gene expression biomarker is being adopted clinically, further work is necessary to explore the potential clinical utility of gene expression profiling in the nasal epithelium for lung cancer diagnosis, lung cancer risk assessment, and precision medicine for lung cancer treatment and chemoprevention.

PMID- 29463558 TI - Disruption of Wnt/beta-Catenin Exerts Antileukemia Activity and Synergizes with FLT3 Inhibition in FLT3-Mutant Acute Myeloid Leukemia. AB - Purpose: Wnt/beta-catenin signaling is required for leukemic stem cell function. FLT3 mutations are frequently observed in acute myeloid leukemia (AML). Anomalous FLT3 signaling increases beta-catenin nuclear localization and transcriptional activity. FLT3 tyrosine kinase inhibitors (TKI) are used clinically to treat FLT3 mutated AML patients, but with limited efficacy. We investigated the antileukemia activity of combined Wnt/beta-catenin and FLT3 inhibition in FLT3-mutant AML.Experimental Design: Wnt/beta-catenin signaling was inhibited by the beta catenin/CBP antagonist C-82/PRI-724 or siRNAs, and FLT3 signaling by sorafenib or quizartinib. Treatments on apoptosis, cell growth, and cell signaling were assessed in cell lines, patient samples, and in vivo in immunodeficient mice by flow cytometry, Western blot, RT-PCR, and CyTOF.Results: We found significantly higher beta-catenin expression in cytogenetically unfavorable and relapsed AML patient samples and in the bone marrow-resident leukemic cells compared with circulating blasts. Disrupting Wnt/beta-catenin signaling suppressed AML cell growth, induced apoptosis, abrogated stromal protection, and synergized with TKIs in FLT3-mutated AML cells and stem/progenitor cells in vitro The aforementioned combinatorial treatment improved survival of AML-xenografted mice in two in vivo models and impaired leukemia cell engraftment. Mechanistically, the combined inhibition of Wnt/beta-catenin and FLT3 cooperatively decreased nuclear beta catenin and the levels of c-Myc and other Wnt/beta-catenin and FLT3 signaling proteins. Importantly, beta-catenin inhibition abrogated the microenvironmental protection afforded the leukemic stem/progenitor cells.Conclusions: Disrupting Wnt/beta-catenin signaling exerts potent activities against AML stem/progenitor cells and synergizes with FLT3 inhibition in FLT3-mutant AML. These findings provide a rationale for clinical development of this strategy for treating FLT3 mutated AML patients. Clin Cancer Res; 24(10); 2417-29. (c)2018 AACR. PMID- 29463559 TI - Capecitabine Efficacy Is Correlated with TYMP and RB1 Expression in PDX Established from Triple-Negative Breast Cancers. AB - Purpose: Triple-negative breast cancer (TNBC) patients with residual disease after neoadjuvant chemotherapy have a poor outcome. We developed patient-derived xenografts (PDX) from residual tumors to identify efficient chemotherapies and predictive biomarkers in a context of resistance to anthracyclines- and taxanes based treatments.Experimental Design: PDX were established from residual tumors of primary breast cancer patients treated in neoadjuvant setting. TNBC PDX were treated by anthracyclines, taxanes, platins, and capecitabine. Predictive biomarkers were identified by transcriptomic and immunohistologic analysis. Downregulation of RB1 was performed by siRNA in a cell line established from a PDX.Results: Residual TNBC PDX were characterized by a high tumor take, a short latency, and a poor prognosis of the corresponding patients. With the exception of BRCA1/2-mutated models, residual PDX were resistant to anthracyclines, taxanes, and platins. Capecitabine, the oral prodrug of 5-FU, was highly efficient in 60% of PDX, with two models showing complete responses. Prior treatment of a responder PDX with 5-FU increased expression of thymidylate synthase and decreased efficacy of capecitabine. Transcriptomic and IHC analyses of 32 TNBC PDX, including both residual tumors and treatment-naive derived tumors, identified RB1 and TYMP proteins as predictive biomarkers for capecitabine response. Finally, RB1 knockdown in a cell line established from a capecitabine-responder PDX decreased sensitivity to 5-FU treatment.Conclusions: We identified capecitabine as efficient chemotherapy in TNBC PDX models established from residual disease and resistant to anthracyclines, taxanes, and platins. RB1 positivity and high expression of TYMP were significantly associated with capecitabine response. Clin Cancer Res; 24(11); 2605-15. (c)2018 AACR. PMID- 29463560 TI - Molecular Lymph Node Status for Prognostic Stratification of Prostate Cancer Patients Undergoing Radical Prostatectomy with Extended Pelvic Lymph Node Dissection. AB - Purpose: Molecular lymph node (LN) analysis using quantitative polymerase chain reaction (qPCR) detects LN metastases with higher sensitivity than histopathology. However, the prognostic role of molecular LN status in prostate cancer patients treated with radical prostatectomy (RP) and extended pelvic LN dissection (ePLND) is unclear. To investigate the association of molecular compared with histopathologic LN status with biochemical recurrence.Experimental Design: Patients with intermediate and high-risk prostate cancer were prospectively enrolled and underwent RP with ePLND, including the obturator, internal, external, and the common iliac region. LNs >=3 mm were bisected and examined by standard histopathology and qPCR for Kallikrein3 (KLK3) expression. Biochemical recurrence was defined by confirmed postoperative PSA > 0.2 ng/mL.Results: In 111 patients, 2,411 of 3,173 removed LNs were examined by both methods. Histopathology detected 68 LN metastases in 28 (25%) patients. Molecular analysis confirmed elevated KLK3 expression in 65 histopathologic LN metastases of all 28 pN1 patients (pN1/molN1) and additionally reclassified 224 histopathologic negative LNs and 32 (29%) pN0 patients as LN-positive (pN0/molN1).At a median follow-up of 48 months, 52 (47%) patients developed biochemical recurrence. Median biochemical recurrence-free survival was 9 months [95% confidence interval (CI), 0.0-20.1] in pN1/molN1 patients, 24 months (95% CI, 1.7-46.3) in pN0/molN1 patients and was not reached in pN0/molN0 patients (P < 0.001). On multivariable Cox regression analysis, molecular LN status [HR 4.1 (95% CI, 1.9-8.8), P < 0.001] but not histopathologic LN status [HR 1.5 (95% CI, 0.8-3.0), P = 0.198] was confirmed as independent predictor of biochemical recurrence.Conclusions: Molecular LN analysis identified pN0 patients with a high risk of biochemical recurrence and provided superior prognostic information in comparison with histopathology alone.

AB - Monocytes and macrophages play a key role in defending pathogens, removing the dead cells or cell debris, and wound healing. The mammalian target of rapamycin (mTOR) inhibitor rapamycin (RPM) is widely used in clinics to treat patients with organ transplantation or tumors. The role of mTOR in monocyte/macrophage development remains to be clarified. Here we found that mTOR intrinsically controls monocyte/macrophage development, as evidenced by the decreased percentages and cell numbers of CD11b+F4/80+ cells resulting from mTOR inhibition in SCID mice, mTOR-deficient mice, and mixed chimera mice, and the in vitro colony formation and monocyte/macrophage induction assays. However, Lyzs-mTOR knockout mice displayed normal levels of monocytes/macrophages, indicating that mTOR is not essential for the survival and maturation of monocytes/macrophages. Further studies showed that mTOR deficiency significantly reduced macrophage colony-stimulating factor receptor CD115 expression at the transcriptional and translational levels. The molecular mechanism studies indicate that the impaired monocyte/macrophage development caused by mTOR deficiency is mainly a result of the overactivated STAT5 and subsequent downregulation of IRF8, but not the altered cell metabolism and autophagy. Therefore, our work identifies that mTOR is an intrinsic master for monocyte/macrophage development at the early stages through regulating STAT5-IRF8-dependent CD115-expressing pathway. Long-term usage of RPM may cause a defect of myeloid progenitors in bone marrow. PMID- 29463561 TI - Neutrophils provide cellular communication between ileum and mesenteric lymph nodes at graft-versus-host disease onset. AB - Conditioning-induced damage of the intestinal tract plays a critical role during the onset of acute graft-versus-host disease (GVHD). Therapeutic interference with these early events of GVHD is difficult, and currently used immunosuppressive drugs mainly target donor T cells. However, not donor T cells but neutrophils reach the sites of tissue injury first, and therefore could be a potential target for GVHD prevention. A detailed analysis of neutrophil fate during acute GVHD and the effect on T cells is difficult because of the short lifespan of this cell type. By using a novel photoconverter reporter system, we show that neutrophils that had been photoconverted in the ileum postconditioning later migrated to mesenteric lymph nodes (mLN). This neutrophil migration was dependent on the intestinal microflora. In the mLN, neutrophils colocalized with T cells and presented antigen on major histocompatibility complex (MHC)-II, thereby affecting T cell expansion. Pharmacological JAK1/JAK2 inhibition reduced neutrophil influx into the mLN and MHC-II expression, thereby interfering with an early event in acute GVHD pathogenesis. In agreement with this finding, neutrophil depletion reduced acute GVHD. We conclude that neutrophils are attracted to the ileum, where the intestinal barrier is disrupted, and then migrate to the mLN, where they participate in alloantigen presentation. JAK1/JAK2 inhibition can interfere with this process, which provides a potential therapeutic strategy to prevent early events of tissue damage-related innate immune cell activation and, ultimately, GVHD. PMID- 29463563 TI - First-in-human phase 1 clinical study of the IL-15 superagonist complex ALT-803 to treat relapse after transplantation. AB - New therapies for patients with hematologic malignancies who relapse after allogeneic hematopoietic cell transplantation (allo-HCT) are needed. Interleukin 15 (IL-15) is a cytokine that stimulates CD8+ T-cell and natural killer (NK) cell antitumor responses, and we hypothesized this cytokine may augment antileukemia/antilymphoma immunity in vivo. To test this, we performed a first-in human multicenter phase 1 trial of the IL-15 superagonist complex ALT-803 in patients who relapsed >60 days after allo-HCT. ALT-803 was administered to 33 patients via the IV or subcutaneous (SQ) routes once weekly for 4 doses (dose levels of 1, 3, 6, and 10 MUg/kg). ALT-803 was well tolerated, and no dose limiting toxicities or treatment-emergent graft-versus-host disease requiring systemic therapy was observed in this clinical setting. Adverse events following IV administration included constitutional symptoms temporally related to increased serum IL-6 and interferon-gamma. To mitigate these effects, the SQ route was tested. SQ delivery resulted in self-limited injection site rashes infiltrated with lymphocytes without acute constitutional symptoms. Pharmacokinetic analysis revealed prolonged (>96 hour) serum concentrations following SQ, but not IV, injection. ALT-803 stimulated the activation, proliferation, and expansion of NK cells and CD8+ T cells without increasing regulatory T cells. Responses were observed in 19% of evaluable patients, including 1 complete remission lasting 7 months. Thus, ALT-803 is a safe, well tolerated agent that significantly increased NK and CD8+ T cell numbers and function. This immunostimulatory IL-15 superagonist warrants further investigation to augment antitumor immunity alone and combined with other immunotherapies. This trial was registered at www.clinicaltrials.gov as #NCT01885897. PMID- 29463564 TI - Glutaminolysis is a metabolic dependency in FLT3ITD acute myeloid leukemia unmasked by FLT3 tyrosine kinase inhibition. AB - FLT3 internal tandem duplication (FLT3ITD) mutations are common in acute myeloid leukemia (AML) associated with poor patient prognosis. Although new-generation FLT3 tyrosine kinase inhibitors (TKI) have shown promising results, the outcome of FLT3ITD AML patients remains poor and demands the identification of novel, specific, and validated therapeutic targets for this highly aggressive AML subtype. Utilizing an unbiased genome-wide clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9 screen, we identify GLS, the first enzyme in glutamine metabolism, as synthetically lethal with FLT3-TKI treatment. Using complementary metabolomic and gene-expression analysis, we demonstrate that glutamine metabolism, through its ability to support both mitochondrial function and cellular redox metabolism, becomes a metabolic dependency of FLT3ITD AML, specifically unmasked by FLT3-TKI treatment. We extend these findings to AML subtypes driven by other tyrosine kinase (TK) activating mutations and validate the role of GLS as a clinically actionable therapeutic target in both primary AML and in vivo models. Our work highlights the role of metabolic adaptations as a resistance mechanism to several TKI and suggests glutaminolysis as a therapeutically targetable vulnerability when combined with specific TKI in FLT3ITD and other TK activating mutation-driven leukemias. PMID- 29463566 TI - Evaluating the Inpatient Pediatric Ethical Consultation Service. AB - OBJECTIVES: Pediatric ethical consultation services (ECSs) have been proliferating at medical centers, with little data available on evaluating their implementation. The objective of this study was to evaluate the pediatric ECS and understand the ethical issues occurring within a single quaternary-level pediatric hospital. METHODS: A retrospective chart review of documented ethics consultations at a large pediatric hospital from November 2010 to November 2013 was performed and data was abstracted per the US Department of Veterans Affairs' Domains of Ethics in Health Care. An anonymous, prospective survey regarding ethical issues encountered was distributed electronically to ~3500 inpatient staff from November 2013 through January 2014. Ethical domains, demographics, feelings of distress by staff, and location of occurrence data were collected. These data were compared with formally documented ethics consults from the retrospective chart review and ECS activity during the same period. RESULTS: A total of 47 ethics consults were documented between 2010 and 2013, primarily in the domains of end-of-life care (19; 40%) and shared decision-making (17; 36%). Sixty-three staff members (92% female; 42% nurses; 20% attending physicians) logged an encountered ethical issue between November 2013 and January 2014, corresponding to only 5 documented ethics consults in the same time period. Domains included end-of-life care (18; 28.5%), shared decision-making (13; 20.6%), everyday workplace (11; 17.4%), professionalism (8; 12.6%), and resource allocation (7; 11%). Eighty-one percent of subjects reported personal or professional distress. CONCLUSIONS: On the basis of this single-center study in which we reviewed formal documentation, we determined that formal pediatric ECSs are underused, particularly for ethical domains that cause staff members moral distress. PMID- 29463565 TI - An FGFR3/MYC positive feedback loop provides new opportunities for targeted therapies in bladder cancers. AB - FGFR3 alterations (mutations or translocation) are among the most frequent genetic events in bladder carcinoma. They lead to an aberrant activation of FGFR3 signaling, conferring an oncogenic dependence, which we studied here. We discovered a positive feedback loop, in which the activation of p38 and AKT downstream from the altered FGFR3 upregulates MYC mRNA levels and stabilizes MYC protein, respectively, leading to the accumulation of MYC, which directly upregulates FGFR3 expression by binding to active enhancers upstream from FGFR3 Disruption of this FGFR3/MYC loop in bladder cancer cell lines by treatment with FGFR3, p38, AKT, or BET bromodomain inhibitors (JQ1) preventing MYC transcription decreased cell viability in vitro and tumor growth in vivo A relevance of this loop to human bladder tumors was supported by the positive correlation between FGFR3 and MYC levels in tumors bearing FGFR3 mutations, and the decrease in FGFR3 and MYC levels following anti-FGFR treatment in a PDX model bearing an FGFR3 mutation. These findings open up new possibilities for the treatment of bladder tumors displaying aberrant FGFR3 activation. PMID- 29463567 TI - Single-molecule imaging reveals dynamic biphasic partition of RNA-binding proteins in stress granules. AB - Stress granules (SGs) are cytosolic, nonmembranous RNA-protein complexes. In vitro experiments suggested that they are formed by liquid-liquid phase separation; however, their properties in mammalian cells remain unclear. We analyzed the distribution and dynamics of two paradigmatic RNA-binding proteins (RBPs), Ras GTPase-activating protein SH3-domain-binding protein (G3BP1) and insulin-like growth factor II mRNA-binding protein 1 (IMP1), with single-molecule resolution in living neuronal cells. Both RBPs exhibited different exchange kinetics between SGs. Within SGs, single-molecule localization microscopy revealed distributed hotspots of immobilized G3BP1 and IMP1 that reflect the presence of relatively immobile nanometer-sized nanocores. We demonstrate alternating binding in nanocores and anomalous diffusion in the liquid phase with similar characteristics for both RBPs. Reduction of low-complexity regions in G3BP1 resulted in less detectable mobile molecules in the liquid phase without change in binding in nanocores. The data provide direct support for liquid droplet behavior of SGs in living cells and reveal transient binding of RBPs in nanocores. Our study uncovers a surprising disconnect between SG partitioning and internal diffusion and interactions of RBPs.

PMID- 29463568 TI - An exome-wide sequencing study of lipid response to high-fat meal and fenofibrate in Caucasians from the GOLDN cohort. AB - Our understanding of genetic influences on the response of lipids to specific interventions is limited. In this study, we sought to elucidate effects of rare genetic variants on lipid response to a high-fat meal challenge and fenofibrate (FFB) therapy in the Genetics of Lipid Lowering Drugs and Diet Network (GOLDN) cohort using an exome-wide sequencing-based association study. Our results showed that the rare coding variants in ITGA7, SIPA1L2, and CEP72 are significantly associated with fasting LDL cholesterol response to FFB (P = 1.24E-07), triglyceride postprandial area under the increase (AUI) (P = 2.31E-06), and triglyceride postprandial AUI response to FFB (P = 1.88E-06), respectively. We sought to replicate the association for SIPA1L2 in the Heredity and Phenotype Intervention (HAPI) Heart Study, which included a high-fat meal challenge but not FFB treatment. The associated rare variants in GOLDN were not observed in the HAPI Heart study, and thus the gene-based result was not replicated. For functional validation, we found that gene transcript level of SIPA1L2 is associated with triglyceride postprandial AUI (P < 0.05) in GOLDN. Our study suggests unique genetic mechanisms contributing to the lipid response to the high fat meal challenge and FFB therapy.

AB - Mutant forms of p53 protein often possess protumorigenic functions, conferring increased survival and migration to tumor cells via their "gain-of-function" activity. Whether and how a common polymorphism in TP53 at amino acid 72 (Pro72Arg; referred to here as P72 and R72) impacts this gain of function has not been determined. We show that mutant p53 enhances migration and metastasis of tumors through the ability to bind and regulate PGC-1alpha and that this regulation is markedly impacted by the codon 72 polymorphism. Tumor cells with the R72 variant of mutant p53 show increased PGC-1alpha function along with greatly increased mitochondrial function and metastatic capability. Breast cancers containing mutant p53 and the R72 variant show poorer prognosis compared with P72. The combined results reveal PGC-1alpha as a novel "gain-of-function" partner of mutant p53 and indicate that the codon 72 polymorphism influences the impact of mutant p53 on metabolism and metastasis. PMID- 29463575 TI - Closing in on the Mechanisms of Pulsatile Insulin Secretion. AB - Insulin secretion from pancreatic islet beta-cells occurs in a pulsatile fashion, with a typical period of ~5 min. The basis of this pulsatility in mouse islets has been investigated for more than four decades, and the various theories have been described as either qualitative or mathematical models. In many cases the models differ in their mechanisms for rhythmogenesis, as well as other less important details. In this Perspective, we describe two main classes of models: those in which oscillations in the intracellular Ca2+ concentration drive oscillations in metabolism, and those in which intrinsic metabolic oscillations drive oscillations in Ca2+ concentration and electrical activity. We then discuss nine canonical experimental findings that provide key insights into the mechanism of islet oscillations and list the models that can account for each finding. Finally, we describe a new model that integrates features from multiple earlier models and is thus called the Integrated Oscillator Model. In this model, intracellular Ca2+ acts on the glycolytic pathway in the generation of oscillations, and it is thus a hybrid of the two main classes of models. It alone among models proposed to date can explain all nine key experimental findings, and it serves as a good starting point for future studies of pulsatile insulin secretion from human islets. PMID- 29463577 TI - Evaluation of the quality of RNA extracted from archival FFPE glioblastoma and epilepsy surgical samples for gene expression assays. AB - AIMS: Histopathological tissue samples are being increasingly used as sources of nucleic acids in molecular pathology translational research. This study investigated the suitability of glioblastoma and control central nervous system (CNS) formalin-fixed paraffin embedded (FFPE) tissue-derived RNA for gene expression analyses. METHODS: Total RNA was extracted from control (temporal lobe resection tissue) and glioblastoma FFPE tissue samples. RNA purity (260/280 ratios) was determined and RNA integrity number (RIN) analysis was performed. RNA was subsequently used for RT-qPCR for two reference genes, 18S and GAPDH. RESULTS: Reference gene expression was equivalent between control and glioblastoma tissue when using RNA extracted from FFPE tissue, which has key implications for biological normalisation for CNS gene expression studies. There was a significant difference between the mean RIN values of control and glioblastoma FFPE tissue. There was no significant correlation between 260/280 or RIN values versus total RNA yield. The age of the tissue blocks did not influence RNA yield, fragmentation or purity. There was no significant correlation between RIN or 260/280 ratios and mean qPCR cycle threshold for either reference gene. CONCLUSIONS: This study showed that routinely available CNS FFPE tissue is suitable for RNA extraction and downstream gene expression studies, even after 60 months of storage. Substantial RNA fragmentation associated with glioblastoma and control FFPE tissue blocks did not preclude downstream RT-qPCR gene expression analyses. Cross validation with both archival and prospectively collated FFPE specimens is required to further demonstrate that CNS tissue blocks can be used in novel translational molecular biomarker studies.

AB - OBJECTIVE: To describe sex aspects on extent of coronary artery disease (CAD) and prognosis in a contemporary population with type 1 diabetes. RESEARCH DESIGN AND METHODS: All patients undergoing coronary angiography, 2001-2013, included in the Swedish Coronary Angiography and Angioplasty Registry and the Swedish National Diabetes Register as type 1 diabetes were followed for mortality until 31 December 2013. The coronary angiogram was classified into normal, one-vessel disease, two-vessel disease, three-vessel disease, and left main stem disease. RESULTS: In all, 2,776 patients (42% women) with mean age 58 years (SD 11) were followed for 7.2 years (SD 2.2). Diabetes duration was longer in women (37 +/- 14 vs. 34 +/- 14 years in men; P < 0.001), who also had more retinopathy (68% vs. 65%; P = 0.050), whereas microalbuminuria was less common (41% vs. 51%; P < 0.001). Indications for coronary angiography did not substantially differ in women and men. The extent of CAD was somewhat less severe in women (normal angiogram 23.5% vs. 19.1%, three-vessel and left main stem disease 34.5% vs. 40.4%; P = 0.002), whereas mortality did not differ (adjusted hazard ratio 1.03 [95% CI 0.88-1.20]; P = 0.754). The standard mortality ratio for women the first year was 7.49 (5.73-9.62) and for men was 4.58 (3.60-5.74). CONCLUSIONS: In patients with type 1 diabetes admitted for coronary angiography, the extent of CAD was almost similar in women and men, and total long-term mortality did not differ. Type 1 diabetes was associated with higher mortality risk in women than in men when compared with the general population. These data support that type 1 diabetes attenuates the cardiovascular risk difference seen in men and women in the general population. PMID- 29463581 TI - A Novel Mechanism for Activation of GLI1 by Nuclear SMO That Escapes Anti-SMO Inhibitors. AB - Small-molecule inhibitors of the Hedgehog (HH) pathway receptor Smoothened (SMO) have been effective in treating some patients with basal cell carcinoma (BCC), where the HH pathway is often activated, but many patients respond poorly. In this study, we report the results of investigations on PTCH1 signaling in the HH pathway that suggest why most patients with BCC respond poorly to SMO inhibitors. In immortalized human keratinocytes, PTCH1 silencing led to the generation of a compact, holoclone-like morphology with increased expression of SMO and the downstream HH pathway transcription factor GLI1. Notably, although siRNA silencing of SMO in PTCH1-silenced cells was sufficient to suppress GLI1 activity, this effect was not phenocopied by pharmacologic inhibition of SMO, suggesting the presence of a second undefined pathway through which SMO can induce GLI1. Consistent with this possibility, we observed increased nuclear localization of SMO in PTCH1-silenced cells as mediated by a putative SMO nuclear/nucleolar localization signal [N(o)LS]. Mutational inactivation of the N(o)LS ablated this increase and suppressed GLI1 induction. Immunohistologic analysis of human and mouse BCC confirmed evidence of nuclear SMO, although the pattern was heterogeneous between tumors. In PTCH1-silenced cells, >80% of the genes found to be differentially expressed were unaffected by SMO inhibitors, including the putative BCC driver gene CXCL11. Our results demonstrate how PTCH1 loss results in aberrant regulation of SMO-independent mechanisms important for BCC biology and highlights a novel nuclear mechanism of SMO-GLI1 signaling that is unresponsive to SMO inhibitors.Significance: This study describes novel noncanonical Hedgehog signaling, where SMO enters the nucleus to activate GLI1, a mode that is unaffected by SMO inhibitors, thus prompting re-evaluation of current BCC treatment as well as new potential therapies targeting nuclear SMO.

AB - The molecular pathways driving mesenchymal glioblastoma (GBM) are still not well understood. We report here that truncated glioma-associated oncogene homolog 1 (tGLI1) is a tumor-specific transcription factor that facilitates GBM growth, is enriched in the mesenchymal subtype of GBM and glioma stem cells (GSC), and promotes mesenchymal GSC by upregulating transcription of CD44. In an orthotopic GBM xenograft mouse model, tGLI1-overexpressing tumors grew more aggressively with increased proliferation and angiogenesis compared with control and GLI1 overexpressing xenografts. tGLI1 was highly expressed in GBM clinical specimens but undetectable in normal brains, whereas GLI1 was expressed in both tissues. A tGLI1 activation signature (tGAS) correlated with glioma grade, tumor angiogenesis, and poor overall survival, and GBMs with high tGAS were enriched with mesenchymal GBM/GSC gene signatures. Neurospheres contained increased levels of tGLI1, but not GLI1, compared with the monolayer culture; mesenchymal GSC expressed more tGLI1 than proneural GSC. Ectopic tGLI1 expression enhanced the ability of mesenchymal GSC to yield neurospheres in vitro and to form tumors in mouse brains. Selective tGLI1 knockdown reduced neurosphere formation of GBM cells. tGLI1 bound to and transactivated the promoter of the CD44 gene, a marker and mediator for mesenchymal GSC, leading to its expression. Collectively, these findings advance our understanding of GBM biology by establishing tGLI1 as a novel transcriptional activator of CD44 and a novel mediator of mesenchymal GBM and GSC.Significance: These findings highlight the role of a tumor-specific gain of-function transcription factor tGLI1 in mesenchymal glioma stem cell maintenance and mesenchymal GBM growth.

AB - BACKGROUND: The Advisory Committee on Immunization Practices currently recommends pregnant women receive influenza and tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccines. There are limited studies of the long term safety in infants for vaccines administered during pregnancy. We evaluate whether maternal receipt of influenza and Tdap vaccines increases the risk of infant hospitalization or death in the first 6 months of life. METHODS: We included singleton, live birth pregnancies in the Vaccine Safety Datalink between 2004 and 2014. Outcomes were infant hospitalizations and mortality in the first 6 months of life. We performed a case-control study matching case patients and controls 1:1 and used conditional logistic regression to estimate odds ratios for maternal exposure to influenza and/or Tdap vaccines in pregnancy. RESULTS: There were 413 034 live births in our population. Of these, 25 222 infants had hospitalizations and 157 infants died in the first 6 months of life. We found no association between infant hospitalization and maternal influenza (adjusted odds ratio: 1.00; 95% confidence interval [CI]: 0.96-1.04) or Tdap (adjusted odds ratio: 0.94; 95% CI: 0.88-1.01) vaccinations. We found no association between infant mortality and maternal influenza (adjusted odds ratio: 0.96; 95% CI: 0.54 1.69) or Tdap (adjusted odds ratio: 0.44; 95% CI: 0.17-1.13) vaccinations. CONCLUSIONS: We found no association between vaccination during pregnancy and risk of infant hospitalization or death in the first 6 months of life. These findings support the safety of current recommendations for influenza and Tdap vaccination during pregnancy. PMID- 29463583 TI - Alterations in placental long chain polyunsaturated fatty acid metabolism in human intrauterine growth restriction. AB - Fatty acids (FA) are critical for fetal brain development and are transferred across the placenta by membrane-bound FA transport proteins (FATP), translocases (FAT/CD36), and cytosolic binding proteins (FABP). The cytosolic protein perilipin-2 aids in neutral lipid storage within lipid droplets. Decreased placental nutrient transport is believed to contribute to intrauterine growth restriction (IUGR); however, IUGR placental lipid transport and metabolism are poorly understood. We hypothesized that protein expression of FATPs, FABPs, and perilipin-2 in human placenta is decreased and placental lipid content and incorporation into lipid classes are reduced in IUGR. Placental tissue of idiopathic IUGR (n=25) and gestational age-matched, appropriately grown for gestational age (AGA) fetuses (n=19) was collected. We determined protein expression of FABP4 and perilipin-2 in placental homogenate and FATPs (2, 4, 6, CD36) in syncytiotrophoblast microvillous plasma membrane (MVM) by Western blot. Lipid droplet area (Oil Red O stain) and cellular FA content (GC/MS) were measured in chorionic villous tissue. MVM expression of FATP6 and CD36 was significantly increased in IUGR. The concentrations of seven n-6 and n-3 species long chain polyunsaturated FAs (LCPUFA) were significantly increased in the triglyceride fraction in IUGR vs AGA placenta. In summary, MVM FATP6 and CD36 protein expression is increased and LCPUFA are preferentially routed toward cellular storage in TG in the IUGR placenta, possibly to protect against oxidative stress associated with cellular FA accumulation. We speculate that these changes may be caused by impaired efflux of FA across the fetal-facing syncytiotrophoblast basal plasma membrane in IUGR placenta. PMID- 29463585 TI - Domestic violence: a cross-sectional study among pregnant women in different regions of Sri Lanka. AB - OBJECTIVES: The aims of this study were to assess the regional differences in domestic violence among pregnant women in the capital district and in the tea plantation sector of Sri Lanka, to explore potential contributory factors and to assess whether healthcare workers addressed domestic violence and disclosure among survivors. DESIGN: A cross-sectional study was carried out using interviewer-administered Abuse Assessment Screen. SETTING: Fifty-seven antenatal clinic centres in the capital district and 30 in the tea plantation sector. PARTICIPANTS: Pregnant women between 6 and 40 weeks of gestational age. In the capital district, 1375 women were recruited from antenatal clinic centres in the urban (n=25) and in the rural areas (n=32), and 800 women from 30 centres in the tea plantation sector. The response rate in the capital district was 95.6% and 96.7% in the tea plantation sector. RESULTS: Among the total sample of pregnant women (n=2088), the prevalence of 'ever abused' was 38.6%, and the prevalence of 'currently abused' was 15.9%. 'Ever abused' (31.5% vs 50.8%) and 'currently abused' (10% vs 25.8%) were significantly higher (P<0.001) among the women living in the tea plantation sector. 'Ever abused' was associated with living in the tea plantation sector, being employed, living far from gender-based violence care centre and of Muslim ethnicity, after adjusting for age, education and family income. Only 38.8% of all participants had been asked by healthcare workers about abuse. Living in the tea plantation sector and lower level of education were associated with not being asked. Among those who reported 'ever abused', only 8.7% had disclosed the experience to a healthcare worker. CONCLUSION: Domestic violence was prevalent and highest among women in the tea plantation sector compared with the capital district. The capacity of healthcare workers in addressing domestic violence should be increased. PMID- 29463584 TI - Pregnancy diet and offspring asthma risk over a 10-year period: the Lifeways Cross Generation Cohort Study, Ireland. AB - OBJECTIVE: The association of maternal pregnancy diet with offspring asthma risk have been reported. However, literature on longitudinal patterns of asthma risk relative to intrauterine nutrient exposure is limited. We aimed to establish whether vegetable, oily fish and vitamin D intake during pregnancy are associated with childhood asthma risk over a 10-year period in the Irish Republic. DESIGN: Mother-child pairs (n=897) from the Lifeways prospective birth cohort, with data on nutrient intake during pregnancy and asthma status, respectively, were eligible for inclusion in the analysis. Data on socioeconomic and morbidity indicators over 10 years of follow-up on mothers and the index child were collected through self-administered questionnaires. Asthma status as diagnosed by the general practitioner at any time point over 10 years was related to maternal vegetable, oily fish and vitamin D intake during pregnancy, while adjusting for gestational age, socioeconomic status, smoking at delivery, breast feeding, season of birth and supplement use. Data were modelled with a marginal model on correlated observations over time within individuals. RESULTS: In the fully adjusted model, asthma was inversely associated with higher daily average intake of oily fish (OR 0.23 per serving/day, 95% CI 0.04 to 1.41) and of vegetables (OR 0.96 per serving/day, 95% CI 0.88 to 1.05), but the confidence limits overlapped 1. A higher daily vitamin D intake was associated with reduced odds of asthma (OR 0.93 per MUg/day, 95% CI 0.89 to 0.98). CONCLUSION: This analysis suggests higher daily average intake of vitamin D in pregnancy is associated with asthma risk in offspring over the first 10 years of life. PMID- 29463586 TI - Evaluation of a complex intervention (Engager) for prisoners with common mental health problems, near to and after release: study protocol for a randomised controlled trial. AB - INTRODUCTION: The 'Engager' programme is a 'through-the-gate' intervention designed to support prisoners with common mental health problems as they transition from prison back into the community. The trial will evaluate the clinical and cost-effectiveness of the Engager intervention. METHODS AND ANALYSIS: The study is a parallel two-group randomised controlled trial with 1:1 individual allocation to either: (a) the Engager intervention plus standard care (intervention group) or (b) standard care alone (control group) across two investigation centres (South West and North West of England). Two hundred and eighty prisoners meeting eligibility criteria will take part. Engager is a person centred complex intervention delivered by practitioners and aimed at addressing offenders' mental health and social care needs. It comprises one-to-one support for participants prior to release from prison and for up to 20 weeks postrelease. The primary outcome is change in psychological distress measured by the Clinical Outcomes in Routine Evaluation-Outcome Measure at 6 months postrelease. Secondary outcomes include: assessment of subjective met/unmet need, drug and alcohol use, health-related quality of life and well-being-related quality of life measured at 3, 6 and 12 months postrelease; change in objective social domains, drug and alcohol dependence, service utilisation and perceived helpfulness of services and change in psychological constructs related to desistence at 6 and 12 months postrelease; and recidivism at 12 months postrelease. A process evaluation will assess fidelity of intervention delivery, test hypothesised mechanisms of action and look for unintended consequences. An economic evaluation will estimate the cost-effectiveness. ETHICS AND DISSEMINATION: This study has been approved by the Wales Research Ethics Committee 3 (ref: 15/WA/0314) and the National Offender Management Service (ref: 2015-283). Findings will be disseminated to commissioners, clinicians and service users via papers and presentations. TRIAL REGISTRATION NUMBER: ISRCTN11707331; Pre-results. PMID- 29463587 TI - Regional disparities in the intimate partner sexual violence rate against women in Parana State, Brazil, 2009-2014: an ecological study. AB - OBJECTIVE: Evaluate disparities in a Brazilian state by conducting an analysis to determine whether socioeconomic status was associated with the reported intimate partner sexual violence (IPSV) rates against women. DESIGN: A retrospective, ecological study. SETTINGS: Data retrieved from the Notifiable Diseases Information System database of the Ministry of Health of Brazil. PARTICIPANTS: All cases of IPSV (n=516) against women aged 15-49 years reported in the Notifiable Diseases Information System between 2009 and 2014. OUTCOME MEASURES: The data were evaluated through an exploratory analysis of spatial data. RESULTS: We identified a positive spatial self-correlation in the IPSV rate (0.7105, P<=0.001). Five high-high-type clusters were identified, predominantly in the Metropolitan, West, South Central, Southwest, Southeast and North Central mesoregions, with only one cluster identified in the North Pioneer mesoregion. Our findings also indicated that the associations between the IPSV rate and socioeconomic predictors (women with higher education, civil registry of legal separations, economically active women, demographic density and average female income) were significantly spatially non-stationary; thus, the regression coefficients verified that certain variables in the model were associated with the IPSV rate in some regions of the state. In addition, the geographically weighted regression (GWR) model improved the understanding of the associations between socioeconomic indicators and the IPSV notification rate, showing a better adjustment than the ordinary least square (OLS) model (OLS vs GWR model: R2: 0.95 vs 0.99; Akaike information criterion: 4117.90 vs 3550.61; Moran's I: 0.0905 vs 0.0273, respectively). CONCLUSIONS: IPSV against women was heterogeneous in the state of Parana. The GWR model showed a better fit and enabled the analysis of the distribution of each indicator in the state, which demonstrated the utility of this model for the study of IPSV dynamics and the indication of local determinants of IPSV notification rates. PMID- 29463588 TI - Pathways and cost-effectiveness of routine lung cancer inpatient care in rural Anhui, China: a retrospective cohort study protocol. AB - INTRODUCTION: Routine inpatient care (RIC) for patients with cancer forms various pathways of clinical procedures. Although most individual procedures comprising the pathways have been tested via clinical trials, little is known about the collective cost and effectiveness of the pathways as a whole. This study aims at exploring RIC pathways for patients with lung cancer from rural Anhui, China, and their determinants and economic impacts. METHODS AND ANALYSIS: The study adopts a retrospective cohort design and proceeds in five steps. Step 1 defines the four main categories of study variables, including clinical procedures, direct cost and effectiveness of procedures, and factors affecting use of these procedures and their cost and effectiveness. Step 2 selects a cohort of 5000 patients with lung cancer diagnosed between 1 July 2015 and 30 June 2016 from rural Anhui by clustered random sampling. Step 3 retrieves the records of all the inpatient care episodes due to lung cancer and extracts data about RIC procedures, proximate variables (eg, Karnofsky Performance Status, Lung Function Score) of patient outcomes and related factors (eg, stage of cancer, age, gender), by two independent clinician researchers using a web-based form. Step 4 estimates the direct cost of each of the RIC procedures using micro-costing and collects data about ultimate patient outcomes (survival and progression-free survival) through a follow-up survey of patients and/or their close relatives. Step 5 analyses the data collected and explores pathways of RIC procedures and their relations with patient outcomes, costs, cost:effect ratios, and a whole range of clinical and sociodemographic factors using multivariate regression and path models. ETHICS AND DISSEMINATION: The study protocol has been approved by an authorised ethics committee of Anhui Medical University (reference number: 20170312). Findings from the study will be disseminated through conventional academic routes such as peer reviewed publications and presentations at regional, national and international conferences. TRIAL REGISTRATION NUMBER: ISRCTN25595562. PMID- 29463589 TI - Factors associated with insufficient awareness of breast cancer among women in Northern and Eastern China: a case-control study. AB - OBJECTIVES: To investigate the awareness and knowledge level of breast cancer among Chinese participants. DESIGN: Case-control study. SETTINGS: This study was based on the database of the minister-affiliated hospital key project of the Ministry of Health of the People's Republic of China that included 21 Chinese hospitals between April 2012 and April 2013. PARTICIPANTS: Matched study was designed among 2978 participants with Han ethnicity aged between 25 and 70. PRIMARY AND SECONDARY OUTCOME MEASURES: Student's t-test, Pearson's chi2 test, reliability analysis, exploratory factor analysis, and univariate and multivariate logistic regression analyses were performed to know the level of breast cancer knowledge and find the breast cancer awareness-associated factors. RESULTS: 80.0% (2383/2978) of the participants had poor awareness level of breast cancer. In-depth knowledge of breast cancer such as early symptoms and risk factors was poorly found among them. Television broadcast and relatives or friends with breast cancers were the main sources of information about breast cancer. Of all participants, 72.8% (2167/2978) had heard about breast cancer as a frequent cancer affecting women, and 63.3% (1884/2978) knew that family history of breast cancer was a risk factor for breast cancer. Over half of them were aware that a breast lump could be a symptom of breast cancer. Multivariate analysis identified the following variables that predicted awareness of breast cancer: young age (OR=0.843, 95% CI 0.740 to 0.961), occupation (agricultural worker) (OR=12.831, 95% CI 6.998 to 23.523), high household social status (OR=0.644, 95% CI 0.531 to 0.780), breast hyperplasia history (OR=1.684, 95% CI 1.273 to 2.228), high behavioural prevention score (OR=4.407, 95% CI 3.433 to 5.657). CONCLUSION: Most women were aware of breast cancer as a disease, but their in-depth knowledge of it was poor. More publicity and education programmes to increase breast cancer awareness are necessary and urgent, especially for the ageing women and agricultural workers. PMID- 29463590 TI - Which patients benefit specifically from short-term psychodynamic psychotherapy (STPP) for depression? Study protocol of a systematic review and meta-analysis of individual participant data. AB - INTRODUCTION: Short-term psychodynamic psychotherapy (STPP) is an empirically supported treatment that is often used to treat depression. However, it is largely unclear if certain subgroups of depressed patients can benefit specifically from this treatment method. We describe the protocol for a systematic review and meta-analysis of individual participant data (IPD) aimed at identifying predictors and moderators of STPP for depression efficacy. METHOD AND ANALYSIS: We will conduct a systematic literature search in multiple bibliographic databases (PubMed, PsycINFO, Embase.com, Web of Science and Cochrane's Central Register of Controlled Trials), 'grey literature' databases (GLIN and UMI ProQuest) and a prospective trial register (http://www.controlled trials.com). We will include studies reporting (a) outcomes on standardised measures of (b) depressed (c) adult patients (d) receiving STPP. We will next invite the authors of these studies to share the participant-level data of their trials and combine these data to conduct IPD meta-analyses. The primary outcome for this study is post-treatment efficacy as assessed by a continuous depression measure. Potential predictors and moderators include all sociodemographic variables, clinical variables and psychological patient characteristics that are measured before the start of treatment and are assessed consistently across studies. One-stage IPD meta-analyses will be conducted using mixed-effects models. ETHICS AND DISSEMINATION: Institutional review board approval is not required for this study. We intend to submit reports of the outcomes of this study for publication to international peer-reviewed journals in the fields of psychiatry or clinical psychology. We also intend to present the outcomes at international scientific conferences aimed at psychotherapy researchers and clinicians. The findings of this study can have important clinical implications, as they can inform expectations of STPP efficacy for individual patients, and help to make an informed choice concerning the best treatment option for a given patient.

PMID- 29463591 TI - Optimising gestational weight gain and improving maternal and infant health outcomes through antenatal dietary, lifestyle and physical activity advice: the OPTIMISE randomised controlled trial protocol. AB - INTRODUCTION: Obesity represents a significant health burden, and WHO recognises the importance of preventing weight gain and subsequent development of obesity among adults who are within the healthy weight range. Women of reproductive age have demonstrated high rates of weight gain during pregnancy placing them at risk of becoming overweight or obese. We will evaluate the effects of dietary and physical activity advice on maternal, fetal and infant health outcomes, among pregnant women of normal body mass index (BMI). METHODS AND ANALYSIS: We will conduct a randomised controlled trial, consenting and randomising women with a live singleton pregnancy between 10+0 and 20+0 weeks and BMI 18.5-24.9 kg/m2 at first antenatal visit, from a tertiary maternity hospital. Women randomised to the Lifestyle Advice Group will receive three face-to-face sessions (two with a research dietitian and one with a trained research assistant) and three telephone calls over pregnancy, in which they will be provided with dietary and lifestyle advice and encouraged to make change using a SMART goals approach. Women randomised to the Standard Care Group will receive routine antenatal care. The primary outcome is infant birth weight >4 kg. Secondary outcomes will include adverse infant and maternal outcomes, maternal weight change, maternal diet and physical activity changes, maternal quality of life and emotional well-being, fetal growth and costs of healthcare. We will recruit 624 women to detect a reduction from 8.72% to 3.87% (alpha 0.05 (two-tailed); power 70%) in infants with birth weight >4 kg. Analyses will be intention to treat with estimates reported as relative risks and 95% CIs. ETHICS AND DISSEMINATION: Ethical approval has been obtained from the Women's and Children's Hospital ethics committee. Findings will be disseminated widely via journal publication and conference presentation(s), and participants informed of results. TRIAL REGISTRATION NUMBER: ACTRN12614000583640. PMID- 29463592 TI - Efficacy and safety of ginkgo preparations for attention deficit hyperactivity disorder: a systematic review protocol. AB - INTRODUCTION: Attention deficit hyperactivity disorder (ADHD) is one of the most commonly diagnosed and treated childhood psychiatric disorders. The analogous diagnosis adopted in Europe is hyperkinetic disorder, which is defined in the WHO's International Classification of Diseases 10th edition (ICD-10). Hyperkinetic disorder includes more severe conditions. Ginkgo preparations are used in the treatment of ADHD. The present study will assess the efficacy and safety of ginkgo preparations in the treatment of ADHD in the currently published literature. MATERIALS AND METHODS: All prospective randomised controlled trials (RCTs) will be included in this systematic review. Patients diagnosed with ADHD according to American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders fourth edition (DSM-IV), Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5), ICD-10 or Chinese Classification and Diagnosis of Mental Diseases third edition (CMDD) will be included. A comprehensive search for RCTs to evaluate the effectiveness and tolerance of ginkgo preparations will be performed. The primary outcomes are the ADHD Rating Scale-IV and Revised Conners' Parent Rating Scale. The secondary outcomes are quality of life evaluated by the KINDL scale, adverse effects/events, Conners' Teacher Rating Scale, Strengths and Weaknesses of ADHD Symptoms and Normal Behaviour Scale and Fremdbeurteilungsbogen fur Hyperkinetische Storungen. Exclusion criteria are the following: (1) case reports, not randomised trial, non comparative studies and (2) patients who were not diagnosed based on DSM-IV, DSM 5, ICD-10 or CMDD. The following databases will be searched from their inception until January 2018: Medline, Embase, the Cochrane Central Register of Controlled Trials, Web of Science, China Biology Medicine Disc, China National Knowledge Infrastructure Database, Wanfang Database and Chinese Scientific Journals Database. Two authors will independently perform the study selection, extract the data and assess the study quality and risk of bias. ETHICS AND DISSEMINATION: This systematic review does not require ethics approval. It will be published in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42017077190. PMID- 29463593 TI - Interleukin 33 Signaling Restrains Sporadic Colon Cancer in an Interferon-gamma Dependent Manner. AB - Interleukin 33 (IL33) is an inflammatory cytokine released during necrotic cell death. The epithelium and stroma of the intestine express large amounts of IL33 and its receptor St2. IL33 is therefore continuously released during homeostatic turnover of the intestinal mucosa. Although IL33 can prevent colon cancer associated with inflammatory colitis, the contribution of IL33 signaling to sporadic colon cancer remains unknown. Here, we utilized a mouse model of sporadic colon cancer to investigate the contribution of IL33 signaling to tumorigenesis in the absence of preexisting inflammation. We demonstrated that genetic ablation of St2 enhanced colon tumor development. Conversely, administration of recombinant IL33 reduced growth of colon cancer cell allografts. In reciprocal bone marrow chimeras, the concurrent loss of IL33 signaling within radioresistant nonhematopoietic, and the radiosensitive hematopoietic, compartments was associated with increased tumor burden. We detected St2 expression within the radioresistant mesenchymal cell compartment of the colon whose stimulation with IL33 induced expression of bona fide NF-kappaB target genes. Mechanistically, we discovered that St2 deficiency within the nonhematopoietic compartment coincided with increased abundance of regulatory T cells and suppression of an IFNgamma gene expression signature, whereas IL33 administration triggered IFNgamma expression by tumor allograft-infiltrating T cells. The decrease of this IFNgamma gene expression signature was associated with more aggressive disease in human colon cancer patients, suggesting that lack of IL33 signaling impaired the generation of a potent IFNgamma-mediated antitumor immune response. Collectively, our data reveal that IL33 functions as a tumor suppressor in sporadic colon cancer. Cancer Immunol Res; 6(4); 409-21. (c)2018 AACR. PMID- 29463594 TI - Another way of seeing things.

PMID- 29463595 TI - Proteotranscriptomic Measurements of E6-Associated Protein (E6AP) Targets in DU145 Prostate Cancer Cells. AB - Prostate cancer is a common cause of cancer-related death in men. E6AP (E6 Associated Protein), an E3 ubiquitin ligase and a transcription cofactor, is elevated in a subset of prostate cancer patients. Genetic manipulations of E6AP in prostate cancer cells expose a role of E6AP in promoting growth and survival of prostate cancer cells in vitro and in vivo However, the effect of E6AP on prostate cancer cells is broad and it cannot be explained fully by previously identified tumor suppressor targets of E6AP, promyelocytic leukemia protein and p27. To explore additional players that are regulated downstream of E6AP, we combined a transcriptomic and proteomic approach. We identified and quantified 16,130 transcripts and 7,209 proteins in castration resistant prostate cancer cell line, DU145. A total of 2,763 transcripts and 308 proteins were significantly altered on knockdown of E6AP. Pathway analyses supported the known phenotypic effects of E6AP knockdown in prostate cancer cells and in parallel exposed novel potential links of E6AP with cancer metabolism, DNA damage repair and immune response. Changes in expression of the top candidates were confirmed using real-time polymerase chain reaction. Of these, clusterin, a stress-induced chaperone protein, commonly deregulated in prostate cancer, was pursued further. Knockdown of E6AP resulted in increased clusterin transcript and protein levels in vitro and in vivo Concomitant knockdown of E6AP and clusterin supported the contribution of clusterin to the phenotype induced by E6AP. Overall, results from this study provide insight into the potential biological pathways controlled by E6AP in prostate cancer cells and identifies clusterin as a novel target of E6AP.

AB - BACKGROUND AND OBJECTIVES: The safety of intravenous iron dosing in dialysis is uncertain. Higher-dose intravenous iron may be associated with a higher risk of infections, cardiovascular events, hospitalizations, and mortality. This systematic review aimed to determine the safety of higher-dose versus lower-dose intravenous iron, oral iron, or no iron supplementation in adult patients treated with dialysis. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We searched Medline, EMBASE, Cochrane library, and CINAHL from inception to January 6, 2017 for randomized, controlled trials and observational studies comparing higher-dose intravenous iron with lower-dose intravenous iron, oral iron, or no iron in patients treated with dialysis that had all-cause mortality, infection, cardiovascular events, or hospitalizations as outcomes. RESULTS: Of the 2231 eligible studies, seven randomized, controlled trials and 15 observational studies met inclusion criteria. The randomized, controlled trials showed no association between higher-dose intravenous iron (>400 mg/mo for most studies) and mortality (six studies; n=970; pooled relative risk, 0.93; 95% confidence interval, 0.47 to 1.84; follow-up ranging from 35 days to 26 months) or infection (four studies; n=743; relative risk, 1.02; 95% confidence interval, 0.74 to 1.41). The observational studies showed no association between higher-dose intravenous iron (>200 mg/mo for most studies) and mortality (eight studies; n=241,408; hazard ratio, 1.09; 95% confidence interval, 0.98 to 1.21; follow-up ranging from 3 to 24 months), infection (eight studies; n=135,532; pooled hazard ratio, 1.13; 95% confidence interval, 0.99 to 1.28), cardiovascular events (seven studies; n=135,675; hazard ratio, 1.18; 95% confidence interval, 0.90 to 1.56), or hospitalizations (five studies; n=134,324; hazard ratio, 1.08; 95% confidence interval, 0.97 to 1.19). CONCLUSIONS: Higher-dose intravenous iron does not seem to be associated with higher risk of mortality, infection, cardiovascular events, or hospitalizations in adult patients on dialysis. Strength of this finding is limited by small numbers of participants and events in the randomized, controlled trials and statistical heterogeneity in observational studies. PMID- 29463599 TI - Why is life expectancy in England and Wales 'stalling'? AB - Several independent analyses, by both epidemiologists and actuaries, have concluded that the previous rate of improvement of life expectancy in England and Wales has now slowed markedly, and at older ages may even be reversing. However, although these findings have led the pension industry to reduce estimates of future liabilities, they have failed to elicit any significant concern in the Department of Health and Social Care. In this essay, we review the evidence on changing life expectancy, noting that the problems are greatest among older women. We then estimate the gap between what life expectancy is now and what it might have been had previous trends continued. At age 85, the gap is 0.34 years for women and 0.23 for men. We argue that recent changes cannot be dismissed as a temporary aberration. While the causes of this phenomenon are contested, there is growing evidence to point to the austerity policies implemented in recent years as at least a partial explanation. We conclude by calling for a fully independent enquiry to ascertain what is happening to life expectancy in England and Wales and what should be done about it. PMID- 29463600 TI - Transcriptional Landscape and Regulatory Roles of Small Noncoding RNAs in the Oxidative Stress Response of the Haloarchaeon Haloferax volcanii. AB - Haloarchaea in their natural environment are exposed to hypersalinity, intense solar radiation, and desiccation, all of which generate high levels of oxidative stress. Previous work has shown that haloarchaea are an order of magnitude more resistant to oxidative stress than most mesophilic organisms. Despite this resistance, the pathways haloarchaea use to respond to oxidative stress damage are similar to those of nonresistant organisms, suggesting that regulatory processes might be key to their robustness. Recently, small regulatory noncoding RNAs (sRNAs) were discovered in Archaea under a variety of environmental conditions. We report here the transcriptional landscape and functional roles of sRNAs in the regulation of the oxidative stress response of the model haloarchaeon Haloferax volcanii Thousands of sRNAs, both intergenic and antisense, were discovered using strand-specific sRNA sequencing (sRNA-seq), comprising 25 to 30% of the total transcriptome under no-challenge and oxidative stress conditions, respectively. We identified hundreds of differentially expressed sRNAs in response to hydrogen peroxide-induced oxidative stress in H. volcanii The targets of a group of antisense sRNAs decreased in expression when these sRNAs were upregulated, suggesting that sRNAs are potentially playing a negative regulatory role on mRNA targets at the transcript level. Target enrichment of these antisense sRNAs included mRNAs involved in transposon mobility, chemotaxis signaling, peptidase activity, and transcription factors.IMPORTANCE While a substantial body of experimental work has been done to uncover the functions of small regulatory noncoding RNAs (sRNAs) in gene regulation in Bacteria and Eukarya, the functional roles of sRNAs in Archaea are still poorly understood. This study is the first to establish the regulatory effects of sRNAs on mRNAs during the oxidative stress response in the haloarchaeon Haloferax volcanii Our work demonstrates that common principles for the response to a major cellular stress exist across the 3 domains of life while uncovering pathways that might be specific to the Archaea This work also underscores the relevance of sRNAs in adaptation to extreme environmental conditions. PMID- 29463601 TI - Discovery of Calcium as a Biofilm-Promoting Signal for Vibrio fischeri Reveals New Phenotypes and Underlying Regulatory Complexity. AB - Vibrio fischeri uses biofilm formation to promote symbiotic colonization of its squid host, Euprymna scolopes Control over biofilm formation is exerted at the level of transcription of the symbiosis polysaccharide (syp) locus by a complex set of two-component regulators. Biofilm formation can be induced by overproduction of the sensor kinase RscS, which requires the activities of the hybrid sensor kinase SypF and the response regulator SypG and is negatively regulated by the sensor kinase BinK. Here, we identify calcium as a signal that promotes biofilm formation by biofilm-competent strains under conditions in which biofilms are not typically observed (growth with shaking). This was true for RscS overproducing cells as well as for strains in which only the negative regulator binK was deleted. The latter results provided, for the first time, an opportunity to induce and evaluate biofilm formation without regulator overexpression. Using these conditions, we determined that calcium induces both syp-dependent and bacterial cellulose synthesis (bcs)-dependent biofilms at the level of transcription of these loci. The calcium-induced biofilms were dependent on SypF, but SypF's Hpt domain was sufficient for biofilm formation. These data suggested the involvement of another sensor kinase(s) and led to the discovery that both RscS and a previously uncharacterized sensor kinase, HahK, functioned in this pathway. Together, the data presented here reveal both a new signal and biofilm phenotype produced by V. fischeri cells, the coordinate production of two polysaccharides involved in distinct biofilm behaviors, and a new regulator that contributes to control over these processes.IMPORTANCE Biofilms, or communities of surface-attached microorganisms adherent via a matrix that typically includes polysaccharides, are highly resistant to environmental stresses and are thus problematic in the clinic and important to study. Vibrio fischeri forms biofilms to colonize its symbiotic host, making this organism useful for studying biofilms. Biofilm formation depends on the syp polysaccharide locus and its regulators. Here, we identify a signal, calcium, that induces both SYP-PS and cellulose-dependent biofilms. We also identify a new syp regulator, the sensor kinase HahK, and discover a mutant phenotype for the sensor kinase RscS. This work thus reveals a specific biofilm-inducing signal that coordinately controls two polysaccharides, identifies a new regulator, and clarifies the regulatory control over biofilm formation by V. fischeri.

PMID- 29463603 TI - Membrane curvature and the Tol-Pal complex determine polar localization of the chemoreceptor Tar in E. coli. AB - Chemoreceptors are localized at the cell poles of Escherichia coli and other rod shaped bacteria. Over the years different mechanisms have been put forward to explain this polar localization; from stochastic clustering, membrane curvature driven localization, interactions with the Tol-Pal complex, to nucleoid exclusion. To evaluate these mechanisms, we monitored the cellular localization of the aspartate chemoreceptor Tar in different deletion mutants. We did not find any indication for either stochastic cluster formation or nucleoid exclusion. However, the presence of a functional Tol-Pal complex appeared to be essential to retain Tar at cell poles. Interestingly, Tar still accumulated at midcell in tol and in pal deletion mutants. In these mutants, the protein appears to gather at the base of division septa, a region characterised by strong membrane curvature. Chemoreceptors, like Tar, form trimer-of-dimers that bend the cell membrane due to a rigid tripod structure. The curvature approaches the curvature of the cell membrane generated during cell division, and localization of chemoreceptor tripods at curved membrane areas is therefore energetically favourable as it lowers membrane tension. Indeed, when we introduced mutations in Tar that abolish the rigid tripod structure, the protein was no longer able to accumulate at midcell or cell poles. These findings favour a model where chemoreceptor localization in E. coli is driven by strong membrane curvature and association with the Tol-Pal complex.Importance Bacteria have exquisite mechanisms to sense and to adapt to the environment they live in. One such mechanism involves the chemotaxis signal transduction pathway, in which chemoreceptors specifically bind certain attracting or repelling molecules and transduce the signals to the cell. In different rod-shaped bacteria, these chemoreceptors localize specifically to cell poles. Here, we examined the polar localization of the aspartate chemoreceptor Tar in E. coli, and found that membrane curvature at cell division sites and the Tol-Pal protein complex, localize Tar at cell division sites, the future cell poles. This study shows how membrane curvature can guide localization of proteins in a cell. PMID- 29463604 TI - Regeneration of Escherichia coli from Minicells through Lateral Gene Transfer. AB - Recently, artificial life has been created with artificial materials and methods. Life can be created when genomic DNA molecules are integrated in liposomes containing biochemical reactions for biogenic needs. However, it is not yet known whether the integration of these parts will be able to occur in nature and constitute a living system. I planned to regenerate bacteria from biologically active liposomes by inserting genomic DNA using only natural materials and methods. Minicells of Escherichia coli, containing plasmids and activated SOS proteins, act as protocells. Four new E. coli strains were regenerated from minicells by inserting the genomes by using the system for conjugation between F- and Hfr strains. Cells of the four regenerated strains showed the same genetic markers as the two genome donors. Pulse-field gel electrophoresis of their genomes showed admixing of those of both donors. In addition, the genomes of the four regenerated strains had chimeric genome of the two donors. These results show that synthesis of life can occur in nature without artificial arrangement.IMPORTANCE What is the difference between inanimate objects and organisms? Organisms always have genomic DNA. When organisms lose their genomes, they can neither grow nor reproduce. As the result, organisms turn into inanimate objects without their genomes. In this study, I regenerated microbes from cells that had lost their genomes (cell corpses) by inserting another genome. All steps of regeneration used the natural behavior of microbes. The same regeneration of microbes could happen in nature. These primitive lives have plasticity, which accelerates evolution and provides various kinds of life in the world. PMID- 29463605 TI - Phenazines regulate Nap-dependent denitrification in Pseudomonas aeruginosa biofilms. AB - Microbes in biofilms face the challenge of substrate limitation. In particular, cells in Pseudomonas aeruginosa biofilms growing in the laboratory or during host colonization often become limited for oxygen. Previously we found that phenazines, antibiotics produced by P. aeruginosa, balance the intracellular redox state for cells in biofilms. Here, we show that genes involved in denitrification are induced in phenazine-null (Deltaphz) mutant biofilms grown under an aerobic atmosphere, even in the absence of nitrate. This finding suggests that resident cells employ a bet-hedging strategy to anticipate the potential availability of nitrate and counterbalance their highly reduced redox state. Consistent with our previous characterization of aerobically-grown colonies supplemented with nitrate, we find that the pathway that is induced in Deltaphz colonies combines the nitrate reductase activity of the periplasmic enzyme Nap with downstream reduction of nitrite to nitrogen gas catalyzed by the enzymes Nir, Nor, and Nos. This regulatory relationship differs from the denitrification pathway that functions under anaerobic growth with nitrate as the terminal electron acceptor, which depends on the membrane-associated nitrate reductase Nar. We identify sequences in the promoter regions of the nap and nir operons that are required for the effects of phenazines on expression. We also show that specific phenazines have differential effects on nap gene expression. Finally, we provide evidence that individual steps of the denitrification pathway are catalyzed at different depths within aerobically grown biofilms, suggesting metabolic cross-feeding between community subpopulations.IMPORTANCE An understanding of the unique physiology of cells in biofilms is critical to our ability to treat fungal and bacterial infections. Colony biofilms of the opportunistic pathogen Pseudomonas aeruginosa, grown under an aerobic atmosphere but without nitrate, express a denitrification pathway that differs from that used for anaerobic growth. We report that the components of this pathway are induced by electron acceptor limitation and that they are differentially expressed over biofilm depth. These observations suggest that (i) P. aeruginosa exhibits "bet hedging" in that it expends energy and resources to prepare for nitrate availability when other electron acceptors are absent; and (ii) that cells in distinct biofilm microniches may be able to exchange substrates to catalyze full denitrification. PMID- 29463606 TI - Functional Analyses of the RsmY and RsmZ Small Noncoding Regulatory RNAs in Pseudomonas aeruginosa. AB - Pseudomonas aeruginosa is a Gram-negative opportunistic pathogen with distinct acute and chronic virulence phenotypes. Whereas acute virulence is typically associated with expression of a type III secretion system (T3SS), chronic virulence is characterized by biofilm formation. Many of the phenotypes associated with acute and chronic virulence are inversely regulated by RsmA and RsmF. RsmA and RsmF are both members of the CsrA family of RNA-binding proteins and regulate protein synthesis at the posttranscriptional level. RsmA activity is controlled by two small noncoding regulatory RNAs (RsmY and RsmZ). Bioinformatic analyses suggest that RsmY and RsmZ each have 3 or 4 putative RsmA binding sites. Each predicted binding site contains a GGA sequence presented in the loop portion of a stem-loop structure. RsmY and RsmZ regulate RsmA, and possibly RsmF, by sequestering these proteins from target mRNAs. In this study, we used selective 2'-hydroxyl acylation analyzed by primer extension and mutational profiling (SHAPE-MaP) chemistry to determine the secondary structures of RsmY and RsmZ and functional assays to characterize the contribution of each GGA site to RsmY/RsmZ activity. Our data indicate that RsmA has two preferential binding sites on RsmY and RsmZ, while RsmF has one preferential binding site on RsmY and two sites on RsmZ. Despite RsmF and RsmA sharing a common consensus site, RsmF binding properties are more restrictive than those of RsmA.IMPORTANCE CsrA homologs are present in many bacteria. The opportunistic pathogen Pseudomonas aeruginosa uses RsmA and RsmF to inversely regulate factors associated with acute and chronic virulence phenotypes. RsmA has an affinity for RsmY and RsmZ higher than that of RsmF. The goal of this study was to understand the differential binding properties of RsmA and RsmF by using the RsmY and RsmZ regulatory small RNAs (sRNAs) as a model. Mutagenesis of the predicted RsmA/RsmF binding sites on RsmY and RsmZ revealed similarities in the sites required to control RsmA and RsmF activity in vivo Whereas binding by RsmA was relatively tolerant of binding site mutations, RsmF was sensitive to disruption to all but two of the sites, further demonstrating that the requirements for RsmF binding activity in vivo and in vitro are more stringent than those for RsmA. PMID- 29463607 TI - Reduced atherosclerosis lesion size, inflammatory response in miR-150 knockout mice via macrophage effects. AB - Atherosclerosis is considered to be a chronic inflammatory disease that can lead to severe clinically important cardiovascular events. miR-150 is a small noncoding RNA that significantly enhances inflammatory responses by upregulating endothelial cell proliferation and migration, as well as intravascular environmental homeostasis. However, the exact role of miR-150 in atherosclerosis remains unknown. Here, we investigated the effect of miR-150 deficiency on atherosclerosis development. Using double-knockout (miR-150-/- and ApoE-/-) mice, we measured atherosclerotic lesion size and stability. Meanwhile, we conducted in vivo bone marrow transplantation to identify cellular-level components of the inflammatory response. Compared with mice deficient only in ApoE, the double knockout mice had significantly smaller atherosclerotic lesions and displayed an attenuated inflammatory response. Moreover, miR-150 ablation promoted plaque stabilization via increases in smooth muscle cell and collagen content and decreased macrophage infiltration and lipid accumulation. The in vitro experiments indicated that an inflammatory response with miR-150 deficiency in atherosclerosis results directly from upregulated expression of the cytoskeletal protein, PDZ and LIM domain 1 (PDLIM1), in macrophages. More importantly, the decreases in phosphorylated p65 expression and inflammatory cytokine secretion induced by miR-150 ablation were reversed by PDLIM1 knockdown. These findings suggest that miR-150 is a promising target for the management of atherosclerosis. PMID- 29463608 TI - Generation and Characterization of a Novel Small Biologic Alternative to Proprotein Convertase Subtilisin/Kexin Type 9 (PCSK9) Antibodies, DS-9001a, Albumin Binding Domain-Fused Anticalin Protein. AB - Since it was recently reported that an antibody for proprotein convertase subtilisin/kexin type 9 (PCSK9) reduces the risk of cardiovascular events in a clinical context, PCSK9 inhibition is thought to be an attractive therapy for dyslipidemia. In the present study, we created a novel small biologic alternative to PCSK9 antibodies called DS-9001a, comprising an albumin binding domain fused to an artificial lipocalin mutein (ABD-fused Anticalin protein), which can be produced by a microbial production system. DS-9001a strongly interfered with PCSK9 binding to low-density-lipoprotein receptor (LDL-R) and PCSK9-mediated degradation of LDL-R. In cynomolgus monkeys, single DS-9001a administration significantly reduced the serum LDL-C level up to 21 days (62.4% reduction at the maximum). Moreover, DS-9001a reduced plasma non-high-density-lipoprotein cholesterol and oxidized LDL levels, and their further reductions were observed when atorvastatin and DS-9001a were administered in combination in human cholesteryl ester transfer protein/ApoB double transgenic mice. Additionally, their reductions on the combination of atorvastatin and DS-9001a were more pronounced than those on the combination of atorvastatin and anacetrapib. Besides its favorable pharmacologic profile, DS-9001a has a lower molecular weight (about 22 kDa), yielding a high stoichiometric drug concentration that might result in a smaller administration volume than that in existing antibody therapy. Since bacterial production systems are viewed as more suited to mass production at low cost, DS-9001a may provide a new therapeutic option to treat patients with dyslipidemia. In addition, considering the growing demand for antibody-like drugs, ABD-fused Anticalin proteins could represent a promising new class of small biologic molecules. PMID- 29463609 TI - Outcomes after sudden cardiac arrest in sports centres with and without on-site external defibrillators. AB - OBJECTIVE: Sudden cardiac arrest (SCA) is a rare but tragic event during amateur sports activities. Our aim is to analyse whether availability of automated external defibrillators (AEDs) in amateur sports centres could impact on SCA survival. METHODS: This is an observational study. During an 18-year period, data regarding exercise-related SCA in sports centres were prospectively collected. Survival rates and time to response were compared between centres with an AED already available and centres where an AED was not already present. RESULTS: Out of 252 sports facilities, 207 (82%) acquired an AED during follow-up while 45 (18%) did not. From 1999 to 2014, there were 26 SCAs (24 (92%) men, 54+/-17 years old) with 15 (58%) of them in centres with on-site AED. Neurologically intact survival rates were 93% in centres with on-site AED and 9% in centres without (P<0.001). Presence of on-site AED, presence of shockable rhythm, first assistance by a lay bystander and time to defibrillation were all related to neurological intact survival, but the presence of on-site AED was the only independent predictor in the multivariate analysis. The use of on-site AED resulted in a lower time to first shock when compared with emergency medical system-delivered AED (3.3+/-1.4min vs 7.3+/-3.2 min; P=0.001). CONCLUSIONS: The presence of on-site AEDs is associated with neurologically intact survival after an exercise-related SCA. Continuous efforts are recommended in order to introduce AEDs in sports and fitness centres, implement educational programmes and increase common awareness about SCA. PMID- 29463610 TI - Impact of frequent premature ventricular contractions on pregnancy outcomes. AB - OBJECTIVES: To determine cardiac and fetal/neonatal event rates among pregnant women with premature ventricular contractions (PVCs) and compare with control groups. METHODS: Prospective case-control cohort study: 53 consecutive pregnancies in 49 women referred to the St. Paul's Hospital between 2010 and 2016 with PVC burden >1% in women without underlying cardiac disease. Maternal cardiac and fetal/neonatal outcomes were compared with two pregnant control groups: (1) supraventricular tachycardia (SVT) group of 53 women referred for a history of SVT/SVT in the current pregnancy and (2) low-risk group of 53 women with no cardiac disease. RESULTS: The maximal PVC burden was 9.2% (range 1.1%-58.7%). Six of 53 (11%) pregnancies were complicated by a maternal cardiac event: heart failure n=1 and sustained ventricular tachycardia requiring therapy n=5 as compared with no cardiac events in both control groups. All women with an adverse event had a PVC burden >5%. Seven (13%) pregnancies were complicated by an adverse fetal and/or neonatal event and this was similar to the normal control group (5 (9%), P=0.45) and significantly less than the SVT group (16 (30%), P=0.03). The adverse fetal event was driven by small for gestational age neonates and preterm delivery. CONCLUSIONS: In our cohort of pregnant women with a structurally normal heart and 'high' PVC burden, we found an adverse maternal event rate of 11%, and all events were successfully managed with medical therapy. The rate of adverse fetal events in the PVC group was similar to the normal control group. PMID- 29463611 TI - Evidence for reduced susceptibility to cardiac bradycardias in South Asians compared with Caucasians. AB - OBJECTIVES: To investigate ethnic differences in susceptibility to bradycardias in South Asian and white European patients in the UK by determining rates of permanent pacemaker (PPM) implantation for sinus node dysfunction (SND) and atrioventricular block (AVB) in each ethnic group. METHODS: We carried out a retrospective cohort study into new PPM implantation during the period from 1 May 2006 to 31 March 2014, in patients of South Asian and Caucasian ethnicity resident in Leicestershire, UK. Numbers of individuals at risk in each ethnic group were derived from UK National Census data of 2011. Crude, and age standardised incidence rates and risk ratios per 1000 population of PPM implantation were calculated for Caucasians and South Asians. RESULTS: During the study period, 4883 individuals from the Leicestershire population of 980 328 underwent PPM implantation, a cumulative implantation rate of 4.98/1000 population. The population cumulative PPM implantation rate for SND was 1.74/1000, AVB 2.83/1000 and other indications 0.38/1000 population. The crude incidence in Caucasians (6.15/1000 population) was higher than in South Asians (1.07/1000 population) and remained higher after age standardisation (5.60/1000 vs 2.03/1000, P<0.001). The age-standardised cumulative PPM implantation rates were lower in South Asians for both SND (0.53/1000 in South Asians; 1.97/1000 in Caucasians, P<0.001) and AVB (1.30/1000 in South Asians; 3.17/1000 in Caucasians, P<0.001). Standardised risk ratios (95% CI) for PPM implantation in South Asians compared with Caucasians for all pacing indications, SND and AVB were 0.36 (95% CI 0.36 to 0.37), 0.27 (95% CI 0.27 to 0.28) and 0.41 (95% CI 0.41 to 0.42), respectively. CONCLUSIONS: Rates of PPM implantation are lower in South Asians residing in the UK, compared with Caucasians. This observation raises the possibility of lower inherent susceptibility to bradycardias in South Asians compared with Caucasians. Studies aimed at identifying underlying mechanisms, including possible genetic differences, are warranted. PMID- 29463612 TI - Long-term impact of chronic total occlusion recanalisation in patients with ST elevation myocardial infarction. AB - BACKGROUND: During primary percutaneous coronary intervention (PCI), a concurrent chronic total occlusion (CTO) is found in 10% of patients with ST-elevation myocardial infarction (STEMI). Long-term benefits of CTO-PCI have been suggested; however, randomised data are lacking. Our aim was to determine mid-term and long term clinical outcome of CTO-PCI versus CTO-No PCI in patients with STEMI with a concurrent CTO. METHODS: The Evaluating Xience and left ventricular function in PCI on occlusiOns afteR STEMI (EXPLORE) was a multicentre randomised trial that included 302 patients with STEMI after successful primary PCI with a concurrent CTO. Patients were randomised to either CTO-PCI or CTO-No PCI. The primary end point of the current study was occurrence of major adverse cardiac events (MACE): cardiac death, coronary artery bypass grafting and MI. Other end points were 1 year left ventricular function (LVF); LV-ejection fraction and LV end-diastolic volume and angina status. RESULTS: The median long-term follow-up was 3.9 (2.1 5.0) years. MACE was not significantly different between both arms (13.5% vs 12.3%, HR 1.03, 95% CI 0.54 to 1.98; P=0.93). Cardiac death was more frequent in the CTO-PCI arm (6.0% vs 1.0%, P=0.02) with no difference in all-cause mortality (12.9% vs 6.2%, HR 2.07, 95% CI 0.84 to 5.14; P=0.11). One-year LVF did not differ between both arms. However, there were more patients with freedom of angina in the CTO-PCI arm at 1 year (94% vs 87%, P=0.03). CONCLUSIONS: In this randomised trial involving patients with STEMI with a concurrent CTO, CTO-PCI was not associated with a reduction in long-term MACE compared to CTO-No PCI. One year LVF was comparable between both treatment arms. The finding that there were more patients with freedom of angina after CTO-PCI at 1-year follow-up needs further investigation.

AB - OBJECTIVE: Cardiac catheterisation and implantable cardioverter defibrillator (ICD) insertion are increasingly common following cardiac arrest survival. However, much of the evidence for the benefit is observational, leaving open the possibility that biased patient selection confounds the association between these invasive procedures and improved outcome. We evaluated the likelihood of selection bias in the association between cardiac catheterisation or ICD placement and outcome by measuring long-term outcomes overall and in a cause specific approach that separated cardiac mortality from non-cardiac mortality. METHODS: We performed a multivariable survival analysis of a clinical cohort between 2005 and 2013, with follow-up through 2015. We included patients who had out-of-hospital or inhospital cardiac arrest that survived to discharge, and evaluated the association between cardiac catheterisation or ICD insertion and all-cause, cardiovascular and non-cardiovascular mortality. RESULTS: Among 678 patients who survived cardiac arrest, we observed lower all-cause mortality among patients who underwent cardiac catheterisation (adjusted HR (aHR) 0.40; P<0.01) or ICD insertion (aHR 0.55; P<0.01). However, cause-specific analysis showed that the benefits of cardiac catheterisation and ICD insertion resulted from reduced non-cardiac causes of death (cardiac catheterisation: aHR 0.24, P<0.01; ICD: aHR 0.58, P<0.01), while reduced cardiac cause of death was not associated with cardiac catheterisation (cardiac catheterisation: aHR 0.75, P=0.33). CONCLUSIONS: There is evidence of selection bias in the secondary prevention survival benefit attributable to cardiac catheterisation for patients who survive cardiac arrest. Observational studies that consider its effects on all-cause mortality likely overestimate the potential benefit of this procedure. PMID- 29463614 TI - Consensus guidelines on the optimal management in interventional EUS procedures: results from the Asian EUS group RAND/UCLA expert panel. AB - OBJECTIVES: Interventional endoscopic ultrasonography (EUS) procedures are gaining popularity and the most commonly performed procedures include EUS-guided drainage of pancreatic pseudocyst, EUS-guided biliary drainage, EUS-guided pancreatic duct drainage and EUS-guided celiac plexus ablation. The aim of this paper is to formulate a set of practice guidelines addressing various aspects of the above procedures. METHODS: Formulation of the guidelines was based on the best scientific evidence available. The RAND/UCLA appropriateness methodology (RAM) was used. Panellists recruited comprised experts in surgery, interventional EUS, interventional radiology and oncology from 11 countries. Between June 2014 and October 2016, the panellists met in meetings to discuss and vote on the clinical scenarios for each of the interventional EUS procedures in question. RESULTS: A total of 15 statements on EUS-guided drainage of pancreatic pseudocyst, 15 statements on EUS-guided biliary drainage, 12 statements on EUS guided pancreatic duct drainage and 14 statements on EUS-guided celiac plexus ablation were formulated. The statements addressed the indications for the procedures, technical aspects, pre- and post-procedural management, management of complications, and competency and training in the procedures. All statements except one were found to be appropriate. Randomised studies to address clinical questions in a number of aspects of the procedures are urgently required. CONCLUSIONS: The current guidelines on interventional EUS procedures are the first published by an endoscopic society. These guidelines provide an in-depth review of the current evidence and standardise the management of the procedures. PMID- 29463615 TI - Thioester-Containing Proteins 2 and 4 Affect the Metabolic Activity and Inflammation Response in Drosophila. AB - Drosophila melanogaster is an outstanding model for studying host antipathogen defense. Although substantial progress has been made in understanding how metabolism and immunity are interrelated in flies, little information has been obtained on the molecular players that regulate metabolism and inflammation in Drosophila during pathogenic infection. Recently, we reported that the inactivation of thioester-containing protein 2 (Tep2) and Tep4 promotes survival and decreases the bacterial burden in flies upon infection with the virulent pathogens Photorhabdus luminescens and Photorhabdus asymbiotica Here, we investigated physiological and pathological defects in tep mutant flies in response to Photorhabdus challenge. We find that tep2 and tep4 loss-of-function mutant flies contain increased levels of carbohydrates and triglycerides in the presence or absence of Photorhabdus infection. We also report that Photorhabdus infection leads to higher levels of nitric oxide and reduced transcript levels of the apical caspase-encoding gene Dronc in tep2 and tep4 mutants. We show that Tep2 and Tep4 are upregulated mainly in the fat body rather than the gut in Photorhabdus-infected wild-type flies and that tep mutants contain decreased numbers of Photorhabdus bacteria in both tissue types. We propose that the inactivation of Tep2 or Tep4 in adult Drosophila flies results in lower levels of inflammation and increased energy reserves in response to Photorhabdus, which could confer a survival-protective effect during the initial hours of infection. PMID- 29463616 TI - Absence of Receptor Guanylyl Cyclase C Enhances Ileal Damage and Reduces Cytokine and Antimicrobial Peptide Production during Oral Salmonella enterica Serovar Typhimurium Infection. AB - Nontyphoidal Salmonella disease contributes toward significant morbidity and mortality across the world. Host factors, including gamma interferon, tumor necrosis factor alpha, and gut microbiota, significantly influence the outcome of Salmonella pathogenesis. However, the entire repertoire of host protective mechanisms contributing to Salmonella pathogenicity is not completely appreciated. Here, we investigated the roles of receptor guanylyl cyclase C (GC C), which is predominantly expressed in the intestine and regulates intestinal cell proliferation and fluid-ion homeostasis. Mice deficient in GC-C (Gucy2c-/-) displayed accelerated mortality compared with that for wild-type mice following infection via the oral route, even though both groups possessed comparable systemic Salmonella infection burdens. Survival following intraperitoneal infection remained similar in both groups, indicating that GC-C offered protection via a gut-mediated response. The serum cortisol level was higher in Gucy2c-/- mice than wild-type (Gucy2c+/+) mice, and an increase in infection induced thymic atrophy with a loss of immature CD4+ CD8+ double-positive thymocytes was observed. Accelerated and enhanced damage in the ileum, including submucosal edema, epithelial cell damage, focal tufting, and distortion of the villus architecture, was seen in Gucy2c-/- mice concomitantly with a larger number of ileal tissue-associated bacteria. Transcription of key mediators of Salmonella-induced inflammation (interleukin-22/Reg3beta) was altered in Gucy2c-/ mice in comparison to that in Gucy2c+/+ mice. A reduction in fecal lactobacilli, which are protective against Salmonella infection, was observed in Gucy2c-/- mice. Gucy2c-/- mice cohoused with wild-type mice continued to show reduced amounts of lactobacilli and increased susceptibility to infection. Our study, therefore, suggests that the receptor GC-C confers a survival advantage during gut-mediated Salmonella enterica serovar Typhimurium pathogenesis, presumably by regulating Salmonella effector mechanisms and maintaining a beneficial microbiome. PMID- 29463617 TI - The Chlamydia trachomatis Plasmid and CT135 Virulence Factors Are Not Essential for Genital Tract Infection or Pathology in Female Pig-Tailed Macaques. AB - The Chlamydia trachomatis plasmid and inclusion membrane protein CT135 are virulence factors in the pathogenesis of murine female genital tract infection. To determine if these virulence factors play a similar role in female nonhuman primates, we infected pig-tailed macaques with the same C. trachomatis strains shown to be important in the murine model. Wild-type C. trachomatis and its isogenic mutant strain deficient in both plasmid and CT135 were used to infect macaques. Macaques were given primary and repeated cervicovaginal challenges with the wild-type and mutant strains. The infection rate, infection duration, and antibody response were similar among macaques infected with both strains. Unexpectedly, colposcopy, laparoscopy, and histologic analysis revealed no substantial genital tract pathology following either primary or repeated cervicovaginal challenges. Cytokine analysis of cervicovaginal secretions from both challenged groups revealed low concentrations of interleukin 1beta (IL 1beta) and elevated levels of the interleukin 1 receptor agonist (IL-1RA). We propose that an imbalance of IL-1beta and IL-1RA in macaques is the reason for the mild inflammatory responses observed in infected urogenital tissues. Thus, understanding the pathobiology of chlamydial infection requires a better understanding of host epigenetic and chlamydial genetic factors. Our findings also have implications for understanding the high frequency of asymptomatic infections in humans. PMID- 29463618 TI - Evaluation of the Role of stat3 in Antibody and TH17-Mediated Responses to Pneumococcal Immunization and Infection by Use of a Mouse Model of Autosomal Dominant Hyper-IgE Syndrome. AB - Loss-of-function mutations in the signal transducer and activator of transcription 3 gene (stat3) result in autosomal dominant hyper-IgE syndrome (AD HIES), a condition in which patients have recurrent debilitating infections, including frequent pneumococcal and staphylococcal pneumonias. stat3 mutations cause defective adaptive TH17 cellular responses, an immune mechanism believed to be critical for clearance of pneumococcal colonization and diminished antibody responses. Here we wished to evaluate the role of stat3 in the clearance of pneumococcal carriage and immunity using mice with a stat3 mutation recapitulating AD-HIES. We show here that naive AD-HIES mice have prolonged nasal carriage of pneumococcus compared to WT mice. Mutant and wild-type mice were then immunized with a pneumococcal whole-cell vaccine (WCV) that provides TH17 mediated protection against pneumococcal colonization and antibody-mediated protection against pneumonia and sepsis. WCV-immunized AD-HIES mice made significantly less pneumococcus-specific interleukin-17A (IL-17A) and antibody than WT mice. The WCV-elicited protection against colonization was abrogated in AD-HIES mice, but immunization with WCV still protected AD-HIES mice against aspiration pneumonia/sepsis. Taken together, our results suggest that impaired clearance of nasopharyngeal carriage due to poor adaptive IL-17A responses may contribute to the increased rates of pneumococcal respiratory infection in AD HIES patients. PMID- 29463619 TI - A comparison of direct aspiration versus stent retriever as a first approach ('COMPASS'): protocol. AB - BACKGROUND AND OBJECTIVE: Acute ischemic stroke is a potentially devastating condition and leading cause of morbidity and mortality, affecting an estimated 800 000 people per year in the USA. The natural history of untreated or unrevascularized large vessel occlusions in acute stroke patients results in mortality rates approaching 30%, with only 25% achieving good neurologic outcomes at 90 days. Recently, data have demonstrated that early endovascular recanalization of large vessel occlusions results in better outcomes than medical therapy alone. However, the majority of patients in these studies were treated with a stent retriever based approach. The purpose of COMPASS is to evaluate whether patients treated with a direct aspiration first pass (ADAPT) approach have non-inferior functional outcomes to those treated with a stent retriever as the firstline (SRFL) approach. MATERIALS AND METHODS: All patients who meet the inclusion and exclusion criteria and consent to participate will be enrolled at participating centers. Treatment will be randomly assigned by a central web based system in a 1:1 manner to treatment with either ADAPT or SRFL thrombectomy. Statistical methodology is prespecified with details available in the statistical analysis plan. RESULTS: The trial recently completed enrollment, and data collection/verification is ongoing. The final results will be made available on completion of enrollment and follow-up. CONCLUSIONS: This paper details the design of the COMPASS trial, a randomized, blinded adjudicator, concurrent, controlled trial of patients treated with either ADAPT or SRFL approaches in order to evaluate whether ADAPT results in non-inferior functional outcome.

AB - Infectious intracranial aneurysms (IIAs) are a rare cerebrovascular complication of systemic infections induced by microbial infiltration and degradation of the arterial vessel wall. Studies on the epidemiology and management of IIAs are limited to case reports and retrospective single-center studies, and report a large variability in epidemiological features, management, and outcomes due to the limited sample size. We conducted a systematic review of all published papers on IIAs in the English literature using MEDLINE and SCOPUS database from January 1950 to June 2017. A total of 288 publications describing 1191 patients with IIA (1398 aneurysms) were included and reviewed for epidemiological features, disease features, treatment and outcome. All patients were merged into a single cohort and summary data are presented. The majority of reported IIAs are distally located, relatively small (<5 mm), involve the anterior circulation, are associated with a relatively high rate of rupture, and demonstrate a propensity to multiplicity of aneurysms. Sensitive diagnosis of IIAs requires digital subtraction angiography and not CT angiography or MR angiography. Treatment of ruptured, symptomatic, or enlarging IIAs has evolved over the last 50 years. Endovascular therapy is associated with a high success rate and low morbidity compared with microsurgical and medical management. A treatment algorithm for the management of patients with IIA in various contexts is proposed and the need for prospective multicenter studies is emphasized. PMID- 29463621 TI - Ventilatory support or respiratory muscle training as adjuncts to exercise in obese CPAP-treated patients with obstructive sleep apnoea: a randomised controlled trial. AB - BACKGROUND: Obstructive sleep apnoea (OSA) and obesity are interdependent chronic diseases sharing reduced exercise tolerance and high cardiovascular risk. INTERVENTION: A 3-month intervention with innovative training modalities would further improve functional capacity and cardiovascular health than usual cycle exercise training in already continuous positive airway pressure (CPAP)-treated obese patients with OSA. METHODS: Fifty three patients (35172 cm as compared with women <164 cm. The adjusted odds ratio for preeclampsia for men >186 cm was 1.03 (95% CI, 0.93-1.15) compared with men <178 cm. The association between maternal height and preeclampsia is unlikely to be because of confounding by familial, socioeconomic factors or by fetal genes related to height. The observed association between maternal height and preeclampsia merits further investigation. PMID- 29463628 TI - Looking back and forward: emergency medicine in its 50th year. PMID- 29463627 TI - Spironolactone Versus Clonidine as a Fourth-Drug Therapy for Resistant Hypertension: The ReHOT Randomized Study (Resistant Hypertension Optimal Treatment). AB - : The aim of this study is to compare spironolactone versus clonidine as the fourth drug in patients with resistant hypertension in a multicenter, randomized trial. Medical therapy adherence was checked by pill counting. Patients with resistant hypertension (no office and ambulatory blood pressure [BP] monitoring control, despite treatment with 3 drugs, including a diuretic, for 12 weeks) were randomized to an additional 12-week treatment with spironolactone (12.5-50 mg QD) or clonidine (0.1-0.3 mg BID). The primary end point was BP control during office (<140/90 mm Hg) and 24-h ambulatory (<130/80 mm Hg) BP monitoring. Secondary end points included BP control from each method and absolute BP reduction. From 1597 patients recruited, 11.7% (187 patients) fulfilled the resistant hypertension criteria. Compared with the spironolactone group (n=95), the clonidine group (n=92) presented similar rates of achieving the primary end point (20.5% versus 20.8%, respectively; relative risk, 1.01 [0.55-1.88]; P=1.00). Secondary end point analysis showed similar office BP (33.3% versus 29.3%) and ambulatory BP monitoring (44% versus 46.2%) control for spironolactone and clonidine, respectively. However, spironolactone promoted greater decrease in 24-h systolic and diastolic BP and diastolic daytime ambulatory BP than clonidine. Per-protocol analysis (limited to patients with >=80% adherence to spironolactone/clonidine treatment) showed similar results regarding the primary end point. In conclusion, clonidine was not superior to spironolactone in true resistant hypertensive patients, but the overall BP control was low (~21%). Considering easier posology and greater decrease in secondary end points, spironolactone is preferable for the fourth-drug therapy. CLINICAL TRIAL REGISTRATION: URL: http://www.clinicaltrials.gov.

PMID- 29463641 TI - Ultrasound Elicits Behavioral Responses through Mechanical Effects on Neurons and Ion Channels in a Simple Nervous System. AB - Focused ultrasound has been shown to stimulate excitable cells, but the biophysical mechanisms behind this phenomenon remain poorly understood. To provide additional insight, we devised a behavioral-genetic assay applied to the well-characterized nervous system of Caenorhabditis elegans nematodes. We found that pulsed ultrasound elicits robust reversal behavior in wild-type animals in a pressure-, duration-, and pulse protocol-dependent manner. Responses were preserved in mutants unable to sense thermal fluctuations and absent in mutants lacking neurons required for mechanosensation. Additionally, we found that the worm's response to ultrasound pulses rests on the expression of MEC-4, a DEG/ENaC/ASIC ion channel required for touch sensation. Consistent with prior studies of MEC-4-dependent currents in vivo, the worm's response was optimal for pulses repeated 300-1000 times per second. Based on these findings, we conclude that mechanical, rather than thermal, stimulation accounts for behavioral responses. Further, we propose that acoustic radiation force governs the response to ultrasound in a manner that depends on the touch receptor neurons and MEC-4 dependent ion channels. Our findings illuminate a complete pathway of ultrasound action, from the forces generated by propagating ultrasound to an activation of a specific ion channel. The findings further highlight the importance of optimizing ultrasound pulsing protocols when stimulating neurons via ion channels with mechanosensitive properties.SIGNIFICANCE STATEMENT How ultrasound influences neurons and other excitable cells has remained a mystery for decades. Although it is widely understood that ultrasound can heat tissues and induce mechanical strain, whether or not neuronal activation depends on heat, mechanical force, or both physical factors is not known. We harnessed Caenorhabditis elegans nematodes and their extraordinary sensitivity to thermal and mechanical stimuli to address this question. Whereas thermosensory mutants respond to ultrasound similar to wild-type animals, mechanosensory mutants were insensitive to ultrasound stimulation. Additionally, stimulus parameters that accentuate mechanical effects were more effective than those producing more heat. These findings highlight a mechanical nature of the effect of ultrasound on neurons and suggest specific ways to optimize stimulation protocols in specific tissues. PMID- 29463642 TI - The Effect of Locomotion on Early Visual Contrast Processing in Humans. AB - Most of our knowledge about vision comes from experiments in which stimuli are presented to immobile human subjects or animals. In the case of human subjects, movement during psychophysical, electrophysiological, or neuroimaging experiments is considered to be a source of noise to be eliminated. Animals used in visual neuroscience experiments are typically restrained and, in many cases, anesthetized. In reality, however, vision is often used to guide the motion of awake, ambulating organisms. Recent work in mice has shown that locomotion elevates visual neuronal response amplitudes (Niell and Stryker, 2010; Erisken et al., 2014; Fu et al., 2014; Lee et al., 2014; Mineault et al., 2016) and reduces long-range gain control (Ayaz et al., 2013). Here, we used both psychophysics and steady-state electrophysiology to investigate whether similar effects of locomotion on early visual processing can be measured in humans. Our psychophysical results show that brisk walking has little effect on subjects' ability to detect briefly presented contrast changes and that co-oriented flankers are, if anything, more effective masks when subjects are walking. Our electrophysiological data were consistent with the psychophysics indicating no increase in stimulus-driven neuronal responses while walking and no reduction in surround suppression. In summary, we have found evidence that early contrast processing is altered by locomotion in humans but in a manner that differs from that reported in mice. The effects of locomotion on very low-level visual processing may differ on a species-by-species basis and may reflect important differences in the levels of arousal associated with locomotion.SIGNIFICANCE STATEMENT Mice are the current model of choice for studying low-level visual processing. Recent studies have shown that mouse visual cortex is modulated by behavioral state: primary visual cortex neurons in locomoting mice tend to be more sensitive and less influenced by long-range gain control. Here, we tested these effects in humans by measuring psychophysical detection thresholds and electroencephalography (EEG) responses while subjects walked on a treadmill. We found no evidence of increased contrast sensitivity or reduced surround suppression in walking humans. Our data show that fundamental measurements of early visual processing differ between humans and mice and this has important implications for recent work on the links among arousal, behavior, and vision in these two species. PMID- 29463643 TI - Hyperactivity of Anterior Cingulate Cortex Areas 24a/24b Drives Chronic Pain Induced Anxiodepressive-like Consequences. AB - Pain associates both sensory and emotional aversive components, and often leads to anxiety and depression when it becomes chronic. Here, we characterized, in a mouse model, the long-term development of these sensory and aversive components as well as anxiodepressive-like consequences of neuropathic pain and determined their electrophysiological impact on the anterior cingulate cortex (ACC, cortical areas 24a/24b). We show that these symptoms of neuropathic pain evolve and recover in different time courses following nerve injury in male mice. In vivo electrophysiological recordings evidence an increased firing rate and bursting activity within the ACC when anxiodepressive-like consequences developed, and this hyperactivity persists beyond the period of mechanical hypersensitivity. Whole-cell patch-clamp recordings also support ACC hyperactivity, as shown by increased excitatory postsynaptic transmission and contribution of NMDA receptors. Optogenetic inhibition of the ACC hyperactivity was sufficient to alleviate the aversive and anxiodepressive-like consequences of neuropathic pain, indicating that these consequences are underpinned by ACC hyperactivity.SIGNIFICANCE STATEMENT Chronic pain is frequently comorbid with mood disorders, such as anxiety and depression. It has been shown that it is possible to model this comorbidity in animal models by taking into consideration the time factor. In this study, we aimed at determining the dynamic of different components and consequences of chronic pain, and correlated them with electrophysiological alterations. By combining electrophysiological, optogenetic, and behavioral analyses in a mouse model of neuropathic pain, we show that the mechanical hypersensitivity, ongoing pain, anxiodepressive consequences, and their recoveries do not necessarily exhibit temporal synchrony during chronic pain processing, and that the hyperactivity of the anterior cingulate cortex is essential for driving the emotional impact of neuropathic pain. PMID- 29463644 TI - The inositol-requiring enzyme 1 (IRE1alpha) RNAse inhibitor, 4u8C, is also a potent cellular antioxidant. AB - Inositol-requiring enzyme 1 alpha (IRE1alpha) is an endoplasmic reticulum (ER) transmembrane endonuclease that is activated in response to ER stress as part of the unfolded protein response (UPR). Chronic activation of the UPR has been implicated in the pathogenesis of many common diseases including diabetes, cancer, and neurological pathologies such as Huntington's and Alzheimer's disease. 7-Hydroxy-4-methyl-2-oxo-2H-chromene-8-carbaldehyde (4u8C) is widely used as a specific inhibitor of IRE1alpha ribonuclease activity (IC50 of 6.89 uM in cultured cells). However, in this paper, we demonstrate that 4u8C acts as a potent reactive oxygen species (ROS) scavenger, both in a cell-free assay and in cultured cells, at concentrations lower than that widely used to inhibit IRE1alpha activity. In vitro we show that, 4u8C effectively decreases xanthine/xanthine oxidase catalysed superoxide production with an IC50 of 0.2 uM whereas in cultured endothelial and clonal pancreatic beta-cells, 4u8C inhibits angiotensin II-induced ROS production with IC50 values of 1.92 and 0.29 uM, respectively. In light of this discovery, conclusions reached using 4u8C as an inhibitor of IRE1alpha should be carefully evaluated. However, this unexpected off-target effect of 4u8C may prove therapeutically advantageous for the treatment of pathologies that are thought to be caused by, or exacerbated by, both oxidative and ER stress such as endothelial dysfunction and/or diabetes. PMID- 29463645 TI - Molecular Architecture of the Essential Yeast Histone Acetyltransferase Complex NuA4 Redefines Its Multimodularity. AB - Conserved from yeast to humans, the NuA4 histone acetyltransferase is a large multisubunit complex essential for cell viability through the regulation of gene expression, genome maintenance, metabolism, and cell fate during development and stress. How the different NuA4 subunits work in concert with one another to perform these diverse functions remains unclear, and addressing this central question requires a comprehensive understanding of NuA4's molecular architecture and subunit organization. We have determined the structure of fully assembled native yeast NuA4 by single-particle electron microscopy. Our data revealed that NuA4 adopts a trilobal overall architecture, with each of the three lobes constituted by one or two functional modules. By performing cross-linking coupled to mass spectrometry analysis and in vitro protein interaction studies, we further mapped novel intermolecular interfaces within NuA4. Finally, we combined these new data with other known structural information of NuA4 subunits and subassemblies to construct a multiscale model to illustrate how the different NuA4 subunits and modules are spatially arranged. This model shows that the multiple chromatin reader domains are clustered together around the catalytic core, suggesting that NuA4's multimodular architecture enables it to engage in multivalent interactions with its nucleosome substrate. PMID- 29463646 TI - Mutant Isocitrate Dehydrogenase 1 Disrupts PKM2-beta-Catenin-BRG1 Transcriptional Network-Driven CD47 Expression. AB - A gain-of-function mutation in isocitrate dehydrogenase 1 (IDH1) affects immune surveillance in gliomas. As elevated CD47 levels are associated with immune evasion in cancers, its status in gliomas harboring mutant IDH1 (IDH1-MT cells) was investigated. Decreased CD47 expression in IDH1-R132H-overexpressing cells was accompanied by diminished nuclear beta-catenin, pyruvate kinase isoform M2 (PKM2), and TCF4 levels compared to those in cells harboring wild-type IDH1 (IDH1 WT cells). The inhibition of beta-catenin in IDH1-WT cells abrogated CD47 expression, beta-catenin-TCF4 interaction, and the transactivational activity of beta-catenin/TCF4. The reverse effect was observed in IDH1-MT cells upon the pharmacological elevation of nuclear beta-catenin levels. Genetic and pharmacological manipulation of nuclear PKM2 levels in IDH1-WT and IDH1-MT cells suggested that PKM2 is a positive regulator of the beta-catenin-TCF4 interaction. The Cancer Genome Atlas (TCGA) data sets indicated diminished CD47, PKM2, and beta-catenin levels in IDH1-MT gliomas compared to IDH1-WT gliomas. Also, elevated BRG1 levels with mutations in the ATP-dependent chromatin-remodeling site were observed in IDH1-MT glioma. The ectopic expression of ATPase-deficient BRG1 diminished CD47 expression as well as TCF4 occupancy on its promoter. Sequential chromatin immunoprecipitation (ChIP-re-ChIP) revealed the recruitment of the PKM2-beta-catenin-BRG1-TCF4 complex to the TCF4 site on the CD47 promoter. This occupancy translated into CD47 transcription, as a diminished recruitment of this complex was observed in glioma cells bearing IDH1-R132H. In addition to its involvement in CD47 transcriptional regulation, PKM2-beta-catenin-BRG1 cross talk affected the phagocytosis of IDH1-MT cells by microglia. PMID- 29463647 TI - beta1-Integrin Impacts Rad51 Stability and DNA Double-Strand Break Repair by Homologous Recombination. AB - The molecular mechanisms underlying resistance to radiotherapy in breast cancer cells remain elusive. Previously, we reported that elevated beta1-integrin is associated with enhanced breast cancer cell survival postirradiation, but how beta1-integrin conferred radioresistance was unclear. Ionizing radiation (IR) induced cell killing correlates with the efficiency of DNA double-strand break (DSB) repair, and we found that nonmalignant breast epithelial (S1) cells with low beta1-integrin expression have a higher frequency of S-phase-specific IR induced chromosomal aberrations than the derivative malignant breast (T4-2) cells with high beta1-integrin expression. In addition, there was an increased frequency of IR-induced homologous recombination (HR) repairosome focus formation in T4-2 cells compared with that of S1 cells. Cellular levels of Rad51 in T4-2 cells, a critical factor in HR-mediated DSB repair, were significantly higher. Blocking or depleting beta1-integrin activity in T4-2 cells reduced Rad51 levels, while ectopic expression of beta1-integrin in S1 cells correspondingly increased Rad51 levels, suggesting that Rad51 is regulated by beta1-integrin. The low level of Rad51 protein in S1 cells was found to be due to rapid degradation by the ubiquitin proteasome pathway (UPP). Furthermore, the E3 ubiquitin ligase RING1 was highly upregulated in S1 cells compared to T4-2 cells. Ectopic beta1-integrin expression in S1 cells reduced RING1 levels and increased Rad51 accumulation. In contrast, beta1-integrin depletion in T4-2 cells significantly increased RING1 protein levels and potentiated Rad51 ubiquitination. These data suggest for the first time that elevated levels of the extracellular matrix receptor beta1 integrin can increase tumor cell radioresistance by decreasing Rad51 degradation through a RING1-mediated proteasomal pathway. PMID- 29463648 TI - Id2 determines intestinal identity through repression of the foregut transcription factor, Irx5. AB - The cellular components and function of the gastrointestinal epithelium exhibit distinct characteristics depending on the region, e.g., stomach or intestine. How these region-specific epithelial characteristics are generated during development remains poorly understood. Here, we report on the involvement of the helix-loop helix inhibitor Id2 in establishing the specific characteristics of the intestinal epithelium. Id2-/- mice developed tumors in the small intestine. Histological analysis indicated that the intestinal tumors were derived from gastric metaplasia formed in the small intestine during development. Heterotopic Id2 expression in developing gastric epithelium induced a fate change to intestinal epithelium. Gene expression analysis revealed that foregut-enriched genes encoding Irx3/5 were highly induced in the midgut of Id2-/- embryos, and transgenic mice expressing Irx5 in the midgut endoderm developed tumors recapitulating the characteristics of Id2-/- mice. Altogether, our results demonstrate that Id2 plays a crucial role in the development of regional specificity in the gastrointestinal epithelium. PMID- 29463649 TI - Ligand-Dependent Corepressor (LCoR) Is a Rexinoid-Inhibited Peroxisome Proliferator-Activated Receptor gamma-Retinoid X Receptor alpha Coactivator. AB - The nuclear receptor peroxisome proliferator-activated receptor gamma (PPARgamma) is an essential regulator of placental development. To gain deeper insights into placental PPARgamma signaling, we dissected its regulation of the Muc1 promoter. We find that, unlike prototypic target activation by heterodimeric receptors, which is either stimulated by or refractory to retinoid X receptor (RXR) ligands (rexinoids), the induction of Muc1 by liganded PPARgamma requires RXRalpha but is inhibited by rexinoids. We demonstrate that this inhibition is mediated by the activation function 2 (AF2) domain of RXRalpha and that Muc1 activation entails altered AF2 structures of both PPARgamma and RXRalpha. This unique regulation of Muc1 reflects specific coactivation of PPARgamma-RXRalpha heterodimers by the transcription cofactor ligand-dependent corepressor (LCoR), corroborated by significant downregulation of Muc1 in Lcor-null placentas. LCoR interacts with PPARgamma and RXRalpha in a synergistic fashion via adjacent noncanonical protein motifs, and the AF2 domain of ligand-bound RXRalpha inhibits this interaction. We further identify the transcription factor Kruppel-like factor 6 (KLF6) as a critical regulator of placental development and a component of Muc1 regulation in cooperation with PPARgamma, RXRalpha, and LCoR. Combined, these studies reveal new principles and players in nuclear receptor function in general and placental PPARgamma signaling in particular. PMID- 29463650 TI - Elegant Science. AB - Elegance is a prized quality in science that is associated with simplicity and explanatory power. This essay considers the qualities that make a scientific model, experiment, method, or theory "elegant," with a focus on the life sciences. We propose a definition of elegance that includes clarity, cleverness, correctness, explanatory power, parsimony, and beauty. The pursuit of elegance can improve the quality of science, but elegance must be pursued with caution, as the truth is sometimes inelegant. PMID- 29463651 TI - N-glycosylation of Viral E Protein Is the Determinant for Vector Midgut Invasion by Flaviviruses. AB - Transmission of flaviviruses by hematophagous insects such as mosquitoes requires acquisition of the virus during blood feeding on the host, with midgut as the primary infection site. Here, we report that N-glycosylation of the E protein, which is conserved among most flaviviruses, is critical for the Zika virus (ZIKV) to invade the vector midgut by inhibiting the reactive oxygen species (ROS) pathway of the mosquito immune system. Our data further show that removal of the ZIKV E glycosylation site prevents mosquito infection by flaviviruses via the oral route, whereas there is no effect on infection by intrathoracic microinjection, which bypasses the midgut. Interestingly, the defect in infection of the mosquito midgut by the mutant virus through blood feeding is rescued by reduction of the ROS level by application of vitamin C, a well-known antioxidant. Therefore, our data demonstrate that ZIKV utilizes the glycosylation on the envelope to antagonize the vector immune defense during infection.IMPORTANCE Most flaviviruses, including Zika virus (ZIKV), are transmitted between hosts by arthropod vectors, such as mosquitoes, which acquire the virus during a blood meal. Here, by mutagenesis, we found a major role of the N-glycosylation of flavivirus E protein in its transmission circle, facilitating its survival against the vector immune system during invasion of the mosquito midgut while blood feeding on the host. In spite of the extensive studies of the involvement of N-glycan modification of flavivirus E protein in virus-host interactions, we discovered its critical role in virus-vector interaction and the evolution of flavivirus. Given the deleterious effects of ZIKV on human health, this study might have a significant impact on development of novel transmission-blocking strategies. PMID- 29463652 TI - Ethanolamine Utilization in Bacteria. AB - Ethanolamine (EA) is a valuable source of carbon and/or nitrogen for bacteria capable of its catabolism. Because it is derived from the membrane phospholipid phosphatidylethanolamine, it is particularly prevalent in the gastrointestinal tract, which is membrane rich due to turnover of the intestinal epithelium and the resident microbiota. Intriguingly, many gut pathogens carry the eut (ethanolamine utilization) genes. EA utilization has been studied for about 50 years, with most of the early work occurring in just a couple of species of Enterobacteriaceae Once the metabolic pathways and enzymes were characterized by biochemical approaches, genetic screens were used to map the various activities to the eut genes. With the rise of genomics, the diversity of bacteria containing the eut genes and surprising differences in eut gene content were recognized. Some species contain nearly 20 genes and encode many accessory proteins, while others contain only the core catabolic enzyme. Moreover, the eut genes are regulated by very different mechanisms, depending on the organism and the eut regulator encoded. In the last several years, exciting progress has been made in elucidating the complex regulatory mechanisms that govern eut gene expression. Furthermore, a new appreciation for how EA contributes to infection and colonization in the host is emerging. In addition to providing an overview of EA related biology, this minireview will give special attention to these recent advances. PMID- 29463653 TI - Efficient and Scalable Precision Genome Editing in Staphylococcus aureus through Conditional Recombineering and CRISPR/Cas9-Mediated Counterselection. AB - Staphylococcus aureus is an important human pathogen, but studies of the organism have suffered from the lack of a robust tool set for its genetic and genomic manipulation. Here we report the development of a system for the facile and high throughput genomic engineering of S. aureus using single-stranded DNA (ssDNA) oligonucleotide recombineering coupled with clustered regularly interspaced short palindromic repeat (CRISPR)/Cas9-mediated counterselection. We identify recombinase EF2132, derived from Enterococcus faecalis, as being capable of integrating single-stranded DNA oligonucleotides into the S. aureus genome. We found that EF2132 can readily mediate recombineering across multiple characterized strains (3 of 3 tested) and primary clinical isolates (6 of 6 tested), typically yielding thousands of recombinants per transformation. Surprisingly, we also found that some S. aureus strains are naturally recombinogenic at measurable frequencies when oligonucleotides are introduced by electroporation, even without exogenous recombinase expression. We construct a temperature-sensitive, two-vector system which enables conditional recombineering and CRISPR/Cas9-mediated counterselection in S. aureus without permanently introducing exogenous genetic material or unintended genetic lesions. We demonstrate the ability of this system to efficiently and precisely engineer point mutations and large single-gene deletions in the S. aureus genome and to yield highly enriched populations of engineered recombinants even in the absence of an externally selectable phenotype. By virtue of utilizing inexpensive, commercially synthesized synthetic DNA oligonucleotides as substrates for recombineering and counterselection, this system provides a scalable, versatile, precise, inexpensive, and generally useful tool for producing isogenic strains in S. aureus which will enable the high-throughput functional assessment of genome variation and gene function across multiple strain backgrounds.IMPORTANCE Engineering genetic changes in bacteria is critical to understanding the function of particular genes or mutations but is currently a laborious and technically challenging process to perform for the important human pathogen Staphylococcus aureus In an effort to develop methods which are rapid, easy, scalable, versatile, and inexpensive, here we describe a system for incorporating synthetic, mutagenic DNA molecules into the S. aureus genome and for eliminating cells that lack the engineered mutation. This method allows efficient, precise, and high-throughput genetic engineering of S. aureus strains and will facilitate studies seeking to address a variety of issues about the function of particular genes and specific mutations. PMID- 29463654 TI - Emergence of an Extensively Drug-Resistant Salmonella enterica Serovar Typhi Clone Harboring a Promiscuous Plasmid Encoding Resistance to Fluoroquinolones and Third-Generation Cephalosporins. AB - Antibiotic resistance is a major problem in Salmonella enterica serovar Typhi, the causative agent of typhoid. Multidrug-resistant (MDR) isolates are prevalent in parts of Asia and Africa and are often associated with the dominant H58 haplotype. Reduced susceptibility to fluoroquinolones is also widespread, and sporadic cases of resistance to third-generation cephalosporins or azithromycin have also been reported. Here, we report the first large-scale emergence and spread of a novel S Typhi clone harboring resistance to three first-line drugs (chloramphenicol, ampicillin, and trimethoprim-sulfamethoxazole) as well as fluoroquinolones and third-generation cephalosporins in Sindh, Pakistan, which we classify as extensively drug resistant (XDR). Over 300 XDR typhoid cases have emerged in Sindh, Pakistan, since November 2016. Additionally, a single case of travel-associated XDR typhoid has recently been identified in the United Kingdom. Whole-genome sequencing of over 80 of the XDR isolates revealed remarkable genetic clonality and sequence conservation, identified a large number of resistance determinants, and showed that these isolates were of haplotype H58. The XDR S Typhi clone encodes a chromosomally located resistance region and harbors a plasmid encoding additional resistance elements, including the blaCTX-M 15 extended-spectrum beta-lactamase, and carrying the qnrS fluoroquinolone resistance gene. This antibiotic resistance-associated IncY plasmid exhibited high sequence identity to plasmids found in other enteric bacteria isolated from widely distributed geographic locations. This study highlights three concerning problems: the receding antibiotic arsenal for typhoid treatment, the ability of S Typhi to transform from MDR to XDR in a single step by acquisition of a plasmid, and the ability of XDR clones to spread globally.IMPORTANCE Typhoid fever is a severe disease caused by the Gram-negative bacterium Salmonella enterica serovar Typhi. Antibiotic-resistant S Typhi strains have become increasingly common. Here, we report the first large-scale emergence and spread of a novel extensively drug-resistant (XDR) S Typhi clone in Sindh, Pakistan. The XDR S Typhi is resistant to the majority of drugs available for the treatment of typhoid fever. This study highlights the evolving threat of antibiotic resistance in S Typhi and the value of antibiotic susceptibility testing and whole-genome sequencing in understanding emerging infectious diseases. We genetically characterized the XDR S Typhi to investigate the phylogenetic relationship between these isolates and a global collection of S Typhi isolates and to identify multiple genes linked to antibiotic resistance. This S Typhi clone harbored a promiscuous antibiotic resistance plasmid previously identified in other enteric bacteria. The increasing antibiotic resistance in S Typhi observed here adds urgency to the need for typhoid prevention measures. PMID- 29463655 TI - De Novo Assembly and Phasing of Dikaryotic Genomes from Two Isolates of Puccinia coronata f. sp. avenae, the Causal Agent of Oat Crown Rust. AB - Oat crown rust, caused by the fungus Pucinnia coronata f. sp. avenae, is a devastating disease that impacts worldwide oat production. For much of its life cycle, P. coronata f. sp. avenae is dikaryotic, with two separate haploid nuclei that may vary in virulence genotype, highlighting the importance of understanding haplotype diversity in this species. We generated highly contiguous de novo genome assemblies of two P. coronata f. sp. avenae isolates, 12SD80 and 12NC29, from long-read sequences. In total, we assembled 603 primary contigs for 12SD80, for a total assembly length of 99.16 Mbp, and 777 primary contigs for 12NC29, for a total length of 105.25 Mbp; approximately 52% of each genome was assembled into alternate haplotypes. This revealed structural variation between haplotypes in each isolate equivalent to more than 2% of the genome size, in addition to about 260,000 and 380,000 heterozygous single-nucleotide polymorphisms in 12SD80 and 12NC29, respectively. Transcript-based annotation identified 26,796 and 28,801 coding sequences for isolates 12SD80 and 12NC29, respectively, including about 7,000 allele pairs in haplotype-phased regions. Furthermore, expression profiling revealed clusters of coexpressed secreted effector candidates, and the majority of orthologous effectors between isolates showed conservation of expression patterns. However, a small subset of orthologs showed divergence in expression, which may contribute to differences in virulence between 12SD80 and 12NC29. This study provides the first haplotype-phased reference genome for a dikaryotic rust fungus as a foundation for future studies into virulence mechanisms in P. coronata f. sp. avenaeIMPORTANCE Disease management strategies for oat crown rust are challenged by the rapid evolution of Puccinia coronata f. sp. avenae, which renders resistance genes in oat varieties ineffective. Despite the economic importance of understanding P. coronata f. sp. avenae, resources to study the molecular mechanisms underpinning pathogenicity and the emergence of new virulence traits are lacking. Such limitations are partly due to the obligate biotrophic lifestyle of P. coronata f. sp. avenae as well as the dikaryotic nature of the genome, features that are also shared with other important rust pathogens. This study reports the first release of a haplotype-phased genome assembly for a dikaryotic fungal species and demonstrates the amenability of using emerging technologies to investigate genetic diversity in populations of P. coronata f. sp. avenae. PMID- 29463656 TI - Yersinia pestis Targets the Host Endosome Recycling Pathway during the Biogenesis of the Yersinia-Containing Vacuole To Avoid Killing by Macrophages. AB - Yersinia pestis has evolved many strategies to evade the innate immune system. One of these strategies is the ability to survive within macrophages. Upon phagocytosis, Y. pestis prevents phagolysosome maturation and establishes a modified compartment termed the Yersinia-containing vacuole (YCV). Y. pestis actively inhibits the acidification of this compartment, and eventually, the YCV transitions from a tight-fitting vacuole into a spacious replicative vacuole. The mechanisms to generate the YCV have not been defined. However, we hypothesized that YCV biogenesis requires Y. pestis interactions with specific host factors to subvert normal vesicular trafficking. In order to identify these factors, we performed a genome-wide RNA interference (RNAi) screen to identify host factors required for Y. pestis survival in macrophages. This screen revealed that 71 host proteins are required for intracellular survival of Y. pestis Of particular interest was the enrichment for genes involved in endosome recycling. Moreover, we demonstrated that Y. pestis actively recruits Rab4a and Rab11b to the YCV in a type three secretion system-independent manner, indicating remodeling of the YCV by Y. pestis to resemble a recycling endosome. While recruitment of Rab4a was necessary to inhibit YCV acidification and lysosomal fusion early during infection, Rab11b appeared to contribute to later stages of YCV biogenesis. We also discovered that Y. pestis disrupts global host endocytic recycling in macrophages, possibly through sequestration of Rab11b, and this process is required for bacterial replication. These data provide the first evidence that Y. pestis targets the host endocytic recycling pathway to avoid phagolysosomal maturation and generate the YCV.IMPORTANCEYersinia pestis can infect and survive within macrophages. However, the mechanisms that the bacterium use to subvert killing by these phagocytes have not been defined. To provide a better understanding of these mechanisms, we used an RNAi approach to identify host factors required for intracellular Y. pestis survival. This approach revealed that the host endocytic recycling pathway is essential for Y. pestis to avoid clearance by the macrophage. We further demonstrate that Y. pestis remodels the phagosome to resemble a recycling endosome, allowing the bacterium to avoid the normal phagolysosomal maturation pathway. Moreover, we show that infection with Y. pestis disrupts normal recycling in the macrophage and that disruption is required for bacterial replication. These findings provide the first evidence that Y. pestis targets the host endocytic recycling pathway in order to evade killing by macrophages. PMID- 29463657 TI - The Essential Genome of Escherichia coli K-12. AB - Transposon-directed insertion site sequencing (TraDIS) is a high-throughput method coupling transposon mutagenesis with short-fragment DNA sequencing. It is commonly used to identify essential genes. Single gene deletion libraries are considered the gold standard for identifying essential genes. Currently, the TraDIS method has not been benchmarked against such libraries, and therefore, it remains unclear whether the two methodologies are comparable. To address this, a high-density transposon library was constructed in Escherichia coli K-12. Essential genes predicted from sequencing of this library were compared to existing essential gene databases. To decrease false-positive identification of essential genes, statistical data analysis included corrections for both gene length and genome length. Through this analysis, new essential genes and genes previously incorrectly designated essential were identified. We show that manual analysis of TraDIS data reveals novel features that would not have been detected by statistical analysis alone. Examples include short essential regions within genes, orientation-dependent effects, and fine-resolution identification of genome and protein features. Recognition of these insertion profiles in transposon mutagenesis data sets will assist genome annotation of less well characterized genomes and provides new insights into bacterial physiology and biochemistry.IMPORTANCE Incentives to define lists of genes that are essential for bacterial survival include the identification of potential targets for antibacterial drug development, genes required for rapid growth for exploitation in biotechnology, and discovery of new biochemical pathways. To identify essential genes in Escherichia coli, we constructed a transposon mutant library of unprecedented density. Initial automated analysis of the resulting data revealed many discrepancies compared to the literature. We now report more extensive statistical analysis supported by both literature searches and detailed inspection of high-density TraDIS sequencing data for each putative essential gene for the E. coli model laboratory organism. This paper is important because it provides a better understanding of the essential genes of E. coli, reveals the limitations of relying on automated analysis alone, and provides a new standard for the analysis of TraDIS data. PMID- 29463658 TI - Functional and Expression Analyses of the Pneumocystis MAT Genes Suggest Obligate Sexuality through Primary Homothallism within Host Lungs. AB - Fungi of the genus Pneumocystis are obligate parasites that colonize mammals' lungs and are host species specific. Pneumocystis jirovecii and Pneumocystis carinii infect, respectively, humans and rats. They can turn into opportunistic pathogens in immunosuppressed hosts, causing severe pneumonia. Their cell cycle is poorly known, mainly because of the absence of an established method of culture in vitro It is thought to include both asexual and sexual phases. Comparative genomic analysis suggested that their mode of sexual reproduction is primary homothallism involving a single mating type (MAT) locus encompassing plus and minus genes (matMc, matMi, and matPi; Almeida et al., mBio 6:e02250-14, 2015). Thus, each strain would be capable of sexual reproduction alone (self fertility). However, this is a working hypothesis derived from computational analyses that is, in addition, based on the genome sequences of single isolates. Here, we tested this hypothesis in the wet laboratory. The function of the P. jirovecii and P. carinii matMc genes was ascertained by restoration of sporulation in the corresponding mutant of fission yeast. Using PCR, we found the same single MAT locus in all P. jirovecii isolates and showed that all three MAT genes are often concomitantly expressed during pneumonia. Extensive homology searches did not identify other types of MAT transcription factors in the genomes or cis-acting motifs flanking the MAT locus that could have been involved in MAT switching or silencing. Our observations suggest that Pneumocystis sexuality through primary homothallism is obligate within host lungs to complete the cell cycle, i.e., produce asci necessary for airborne transmission to new hosts.IMPORTANCE Fungi of the genus Pneumocystis colonize the lungs of mammals. In immunosuppressed human hosts, Pneumocystis jirovecii may cause severe pneumonia that can be fatal. This disease is one of the most frequent life threatening invasive fungal infections in humans. The analysis of the genome sequences of these uncultivable pathogens suggested that their sexual reproduction involves a single partner (self-fertilization). Here, we report laboratory experiments that support this hypothesis. The function of the three genes responsible for sexual differentiation was ascertained by the restoration of sexual reproduction in the corresponding mutant of another fungus. As predicted by self-fertilization, all P. jirovecii isolates harbored the same three genes that were often concomitantly expressed within human lungs during infection. Our observations suggest that the sexuality of these pathogens relies on the self-fertility of each isolate and is obligate within host lungs to complete the cell cycle and allow dissemination of the fungus to new hosts. PMID- 29463659 TI - A Near-Complete Haplotype-Phased Genome of the Dikaryotic Wheat Stripe Rust Fungus Puccinia striiformis f. sp. tritici Reveals High Interhaplotype Diversity. AB - A long-standing biological question is how evolution has shaped the genomic architecture of dikaryotic fungi. To answer this, high-quality genomic resources that enable haplotype comparisons are essential. Short-read genome assemblies for dikaryotic fungi are highly fragmented and lack haplotype-specific information due to the high heterozygosity and repeat content of these genomes. Here, we present a diploid-aware assembly of the wheat stripe rust fungus Puccinia striiformis f. sp. tritici based on long reads using the FALCON-Unzip assembler. Transcriptome sequencing data sets were used to infer high-quality gene models and identify virulence genes involved in plant infection referred to as effectors. This represents the most complete Puccinia striiformis f. sp. tritici genome assembly to date (83 Mb, 156 contigs, N50 of 1.5 Mb) and provides phased haplotype information for over 92% of the genome. Comparisons of the phase blocks revealed high interhaplotype diversity of over 6%. More than 25% of all genes lack a clear allelic counterpart. When we investigated genome features that potentially promote the rapid evolution of virulence, we found that candidate effector genes are spatially associated with conserved genes commonly found in basidiomycetes. Yet, candidate effectors that lack an allelic counterpart are more distant from conserved genes than allelic candidate effectors and are less likely to be evolutionarily conserved within the P. striiformis species complex and Pucciniales In summary, this haplotype-phased assembly enabled us to discover novel genome features of a dikaryotic plant-pathogenic fungus previously hidden in collapsed and fragmented genome assemblies.IMPORTANCE Current representations of eukaryotic microbial genomes are haploid, hiding the genomic diversity intrinsic to diploid and polyploid life forms. This hidden diversity contributes to the organism's evolutionary potential and ability to adapt to stress conditions. Yet, it is challenging to provide haplotype-specific information at a whole-genome level. Here, we take advantage of long-read DNA sequencing technology and a tailored-assembly algorithm to disentangle the two haploid genomes of a dikaryotic pathogenic wheat rust fungus. The two genomes display high levels of nucleotide and structural variations, which lead to allelic variation and the presence of genes lacking allelic counterparts. Nonallelic candidate effector genes, which likely encode important pathogenicity factors, display distinct genome localization patterns and are less likely to be evolutionary conserved than those which are present as allelic pairs. This genomic diversity may promote rapid host adaptation and/or be related to the age of the sequenced isolate since last meiosis. PMID- 29463662 TI - In This Issue of Diabetes Care. PMID- 29463660 TI - Novel Segment- and Host-Specific Patterns of Enteroaggregative Escherichia coli Adherence to Human Intestinal Enteroids. AB - Enteroaggregative Escherichia coli (EAEC) is an important diarrheal pathogen and a cause of both acute and chronic diarrhea. It is a common cause of pediatric bacterial diarrhea in developing countries. Despite its discovery in 1987, the intestinal tropism of the pathogen remains unknown. Cell lines used to study EAEC adherence include the HEp-2, T-84, and Caco-2 lines, but they exhibit abnormal metabolism and large variations in gene expression. Animal models either do not faithfully manifest human clinical symptoms or are cumbersome and expensive. Using human intestinal enteroids derived from all four segments of the human intestine, we find that EAEC demonstrates aggregative adherence to duodenal and ileal enteroids, with donor-driven differences driving a sheet-like and layered pattern. This contrasts with the colon, where segment-specific tropisms yielded a mesh-like adherence pattern dominated by interconnecting filaments. Very little to no aggregative adherence to jejunal enteroids was observed, regardless of the strain or donor, in contrast to a strong duodenal association across all donors and strains. These unique patterns of intestinal segment- or donor-specific adherence, but not the overall numbers of associated bacteria, were dependent on the major subunit protein of aggregative adherence fimbriae II (AafA), implying that the morphology of adherent clusters and the overall intestinal cell association of EAEC occur by different mechanisms. Our results suggest that we must give serious consideration to inter- and intrapatient variations in what is arguably the first step in pathogenesis, that of adherence, when considering the clinical manifestation of these infections.IMPORTANCE EAEC is a leading cause of pediatric bacterial diarrhea and a common cause of diarrhea among travelers and immunocompromised individuals. Heterogeneity in EAEC strains and lack of a good model system are major roadblocks to the understanding of its pathogenesis. Utilizing human intestinal enteroids to study the adherence of EAEC, we demonstrate that unique patterns of adherence are largely driven by unidentified factors present in different intestinal segments and from different donors. These patterns are also dependent on aggregative adherence fimbriae II encoded by EAEC. These results imply that we must also consider the contribution of the host to understand the pathogenesis of EAEC-induced inflammation and diarrhea.

PMID- 29463661 TI - Microbial Functional Gene Diversity Predicts Groundwater Contamination and Ecosystem Functioning. AB - Contamination from anthropogenic activities has significantly impacted Earth's biosphere. However, knowledge about how environmental contamination affects the biodiversity of groundwater microbiomes and ecosystem functioning remains very limited. Here, we used a comprehensive functional gene array to analyze groundwater microbiomes from 69 wells at the Oak Ridge Field Research Center (Oak Ridge, TN), representing a wide pH range and uranium, nitrate, and other contaminants. We hypothesized that the functional diversity of groundwater microbiomes would decrease as environmental contamination (e.g., uranium or nitrate) increased or at low or high pH, while some specific populations capable of utilizing or resistant to those contaminants would increase, and thus, such key microbial functional genes and/or populations could be used to predict groundwater contamination and ecosystem functioning. Our results indicated that functional richness/diversity decreased as uranium (but not nitrate) increased in groundwater. In addition, about 5.9% of specific key functional populations targeted by a comprehensive functional gene array (GeoChip 5) increased significantly (P < 0.05) as uranium or nitrate increased, and their changes could be used to successfully predict uranium and nitrate contamination and ecosystem functioning. This study indicates great potential for using microbial functional genes to predict environmental contamination and ecosystem functioning.IMPORTANCE Disentangling the relationships between biodiversity and ecosystem functioning is an important but poorly understood topic in ecology. Predicting ecosystem functioning on the basis of biodiversity is even more difficult, particularly with microbial biomarkers. As an exploratory effort, this study used key microbial functional genes as biomarkers to provide predictive understanding of environmental contamination and ecosystem functioning. The results indicated that the overall functional gene richness/diversity decreased as uranium increased in groundwater, while specific key microbial guilds increased significantly as uranium or nitrate increased. These key microbial functional genes could be used to successfully predict environmental contamination and ecosystem functioning. This study represents a significant advance in using functional gene markers to predict the spatial distribution of environmental contaminants and ecosystem functioning toward predictive microbial ecology, which is an ultimate goal of microbial ecology. PMID- 29463665 TI - Assessing Health-Related Quality of Life in Patients With Diabetic Foot Disease: Why Is It Important and How Can We Improve? The 2017 Roger E. Pecoraro Award Lecture. AB - Patient-reported outcomes (PROs) have become an important subject in the area of diabetes-related foot complications. Self-reported health-related quality of life (HRQOL) surveys can provide a generic measure of overall health (global) and can be disease specific (i.e., diabetes) or even region specific (i.e., lower extremity function). Analysis of PRO measures utilizing validated instruments allows health care providers to determine whether medical and surgical treatments are providing patients with the highest level of outcome possible and are actually improving HRQOL. The 36-item Short Form (SF-36), EuroQol five-dimension questionnaire (EQ-5D-5L), and Foot and Ankle Ability Measure (FAAM) are examples of commonly used HRQOL surveys. Low HRQOL has been associated with higher rates of hospital admission and mortality in patients with diabetes. Previous studies have demonstrated that patients with diabetes-related foot disease have low self reported physical quality of life but do not typically report low mental quality of life. The impact of mental quality of life may be underestimated in these patients using the SF-36. In this article, we will discuss several widely used outcome instruments used to measure patient HRQOL and the impact of diabetic foot disease on HRQOL. As health care providers, we must continue to adjust and modify our treatments to achieve the best patient outcomes and associated high quality of life. Assessing PROs will become increasingly important as health care systems transition from a volume-based reimbursement model to a value-based model. PMID- 29463666 TI - Gastrointestinal Symptoms in Diabetes: Prevalence, Assessment, Pathogenesis, and Management. AB - If you haven't measured something, you really don't know much about it.-Karl Pearson (attributed)Gastrointestinal (GI) symptoms represent an important and often unappreciated cause of morbidity in diabetes, although the significance of this burden across the spectrum of patients and the underlying pathophysiology, including the relationship of symptoms with glycemic control, remain poorly defined. The relevance of GI symptoms and the necessity for their accurate assessment have increased with the greater focus on the gut as a therapeutic target for glucose lowering. This review addresses the prevalence, assessment, pathogenesis, and management of GI symptoms in diabetes, beginning with broad principles and then focusing on specific segments of the GI tract. We initially performed a literature search of PubMed by using synonyms and combinations of the following search terms: "gastrointestinal symptoms", "diabetes", "prevalence", "pathogenesis", "diagnosis", and "management". We restricted the search results to English only. Review papers and meta-analyses are presented as the highest level of evidence where possible followed by randomized controlled trials, uncontrolled trials, retrospective and observational data, and expert opinion.

PMID- 29463677 TI - An unexpected link between fatty acid synthase and cholesterol synthesis in proinflammatory macrophage activation. AB - Different immune activation states require distinct metabolic features and activities in immune cells. For instance, inhibition of fatty acid synthase (FASN), which catalyzes the synthesis of long-chain fatty acids, prevents the proinflammatory response in macrophages; however, the precise role of this enzyme in this response remains poorly defined. Consistent with previous studies, we found here that FASN is essential for lipopolysaccharide-induced, Toll-like receptor (TLR)-mediated macrophage activation. Interestingly, only agents that block FASN upstream of acetoacetyl-CoA synthesis, including the well characterized FASN inhibitor C75, inhibited TLR4 signaling, while those acting downstream had no effect. We found that acetoacetyl-CoA could overcome C75's inhibitory effect, whereas other FASN metabolites, including palmitate, did not prevent C75-mediated inhibition. This suggested an unexpected role for acetoacetyl-CoA in inflammation that is independent of its role in palmitate synthesis. Our evidence further suggested that acetoacetyl-CoA arising from FASN activity promotes cholesterol production, indicating a surprising link between fatty acid synthesis and cholesterol synthesis. We further demonstrate that this process is required for TLR4 to enter lipid rafts and facilitate TLR4 signaling. In conclusion, we have uncovered an unexpected link between FASN and cholesterol synthesis that appears to be required for TLR signal transduction and proinflammatory macrophage activation.

AB - The StARkin superfamily comprises proteins with steroidogenic acute regulatory protein-related lipid transfer (StART) domains that are implicated in intracellular, non-vesicular lipid transport. A new family of membrane-anchored StARkins was recently identified, including six members, Lam1-Lam6, in the yeast Saccharomyces cerevisiae. Lam1-Lam4 are anchored to the endoplasmic reticulum (ER) membrane at sites where the ER is tethered to the plasma membrane and proposed to be involved in sterol homeostasis in yeast. To better understand the biological roles of these proteins, we carried out a structure-function analysis of the second StARkin domain of Lam4, here termed Lam4S2. NMR experiments indicated that Lam4S2 undergoes specific conformational changes upon binding sterol, and fluorescence-based assays revealed that it catalyzes sterol transport between vesicle populations in vitro, exhibiting a preference for vesicles containing anionic lipids. Using such vesicles, we found that sterols are transported at a rate of ~50 molecules per Lam4S2 per minute. Crystal structures of Lam4S2, with and without bound sterol, revealed a largely hydrophobic but surprisingly accessible sterol-binding pocket with the 3-OH group of the sterol oriented toward its base. Single or multiple alanine or aspartic acid replacements of conserved lysine residues in a basic patch on the surface of Lam4S2 near the likely sterol entry/egress site strongly attenuated sterol transport. Our results suggest that Lam4S2 engages anionic membranes via a basic surface patch, enabling "head-first" entry of sterol into the binding pocket followed by partial closure of the entryway. Reversal of these steps enables sterol egress. PMID- 29463679 TI - Substrate clustering potently regulates the activity of WW-HECT domain-containing ubiquitin ligases. AB - The Nedd4 family of HECT domain-containing E3 ligases ubiquitinate many transcription factors and signaling proteins, and their activity is tightly regulated. Normally, intramolecular interactions curb the catalytic activity of the HECT domain, but these can be broken by the binding of PY motifs, found on substrate molecules and adaptors, to the WW domains characteristic of this E3 ligase family. This raises the prospect of substrates automatically activating the ligases, frustrating the purpose of ligase regulation. Here we show that soluble protein substrates and adaptors such as alpha arrestins, even with multiple PY elements, cannot activate ligase activity efficiently. However, we found that polymerization or membrane tethering of these substrates dramatically increases the ligase activity both in vivo and in vitro Aggregation of luciferase containing substrates upon heat shock had a similar effect and could also expose cryptic PY elements in the substrates. We inferred that ligase activation critically requires a substantial array of clustered PY motifs and that the formation of such arrays on membranes or in polymeric aggregates may be an essential step in this mode of ligase regulation. We conclude that recruitment of alpha arrestins to membrane receptors and aggregation of unstable proteins after heat shock may be physiologically relevant mechanisms for triggering ubiquitination by Nedd4 family HECT domain-containing E3 ligases. PMID- 29463680 TI - The actin filament twist changes abruptly at boundaries between bare and cofilin decorated segments. AB - Cofilin/ADF proteins are actin-remodeling proteins, essential for actin disassembly in various cellular processes, including cell division, intracellular transport, and motility. Cofilins bind actin filaments cooperatively and sever them preferentially at boundaries between bare and cofilin-decorated (cofilactin) segments. The cooperative binding to actin has been proposed to originate from conformational changes that propagate allosterically from clusters of bound cofilin to bare actin segments. Estimates of the lengths over which these cooperative conformational changes propagate vary dramatically, ranging from 2 to >100 subunits. Here, we present a general, structure-based method for detecting from cryo-EM micrographs small variations in filament geometry (i.e. twist) with single-subunit precision. How these variations correlate with regulatory protein occupancy reveals how far allosteric, conformational changes propagate along filaments. We used this method to determine the effects of cofilin on the actin filament twist. Our results indicate that cofilin-induced changes in filament twist propagate only 1-2 subunits from the boundary into the bare actin segment, independently of the boundary polarity (i.e. irrespective of whether or not the bare actin segment flanks the pointed or barbed-end side of the boundary) and the pyrene fluorophore labeling of actin. These observations indicate that the filament twist changes abruptly at boundaries between bare and cofilin-decorated segments, thereby constraining mechanistic models of cooperative actin filament interactions and severing by cofilin. The methods presented here extend the capability of cryo-EM to analyze biologically relevant deviations from helical symmetry in actin as well as other classes of linear polymers. PMID- 29463682 TI - Metabolism in pluripotency: Both driver and passenger? AB - Pluripotent stem cells (PSCs) are highly proliferative cells characterized by robust metabolic demands to power rapid division. For many years considered a passive component or "passenger" of cell fate determination, cell metabolism is now starting to take center stage as a driver of cell fate outcomes. This review provides an update and analysis of our current understanding of PSC metabolism and its role in self-renewal, differentiation, and somatic cell reprogramming to pluripotency. Moreover, we present evidence on the active roles metabolism plays in shaping the epigenome to influence patterns of gene expression that may model key features of early embryonic development. PMID- 29463681 TI - Bromodomain-containing protein 4-independent transcriptional activation by autoimmune regulator (AIRE) and NF-kappaB. AB - Autoimmune regulator (AIRE) and nuclear factor-kappaB (NF-kappaB) are transcription factors (TFs) that direct the expression of individual genes and gene clusters. Bromodomain-containing protein 4 (BRD4) is an epigenetic regulator that recognizes and binds to acetylated histones. BRD4 also has been reported to promote interactions between the positive transcription elongation factor b (P TEFb) and AIRE or P-TEFb and NF-kappaB subunit p65. Here, we report that AIRE and p65 bind to P-TEFb independently of BRD4. JQ1, a compound that disrupts interactions between BRD4 and acetylated proteins, does not decrease transcriptional activities of AIRE or p65. Moreover, siRNA-mediated inactivation of BRD4 alone or in combination with JQ1 had no effects on AIRE- and NF-kappaB targeted genes on plasmids and in chromatin and on interactions between P-TEFb and AIRE or NF-kappaB. Finally, ChIP experiments revealed that recruitment of P TEFb to AIRE or p65 to transcription complexes was independent of BRD4. We conclude that direct interactions between AIRE, NF-kappaB, and P-TEFb result in efficient transcription of their target genes. PMID- 29463683 TI - Peer review policies in medical student journals. PMID- 29463684 TI - Strategy to reduce E. coli bacteraemia based on cohort data from a London teaching hospital. AB - BACKGROUND AND AIM: In 2017, National Health Service Improvement set a 10% reduction target for Escherichia coli bacteraemia by 2018, followed by a 50% reduction in healthcare-associated Gram-negative bacteraemias by 2022. We analysed consecutive cases of E. coli bacteraemia and devised a strategy to achieve these targets. METHODS: From December 2012 to November 2013, demographic, clinical and microbiological data were prospectively collected on all patients with bacteraemia at the Royal London Hospital in East London, UK. RESULTS: There were 594 significant bacteraemic episodes and 207 (34.8%) were E. coli. Twenty four (11.6%) of the E. coli isolates were extended spectrum beta-lactamase producers, 22 (10.6%) gentamicin resistant and 2 (1.0%) amikacin resistant. The three most common sites of infection were pyelonephritis 105 (56.7%), catheter associated urinary tract infection 22 (10.6%), and other medical devices and procedures that cause bacteraemia 32 (15.5%). In the pyelonephritis group, trimethoprim resistance in urinary isolates was 16/47 (34.0%) compared with 3/47 (6.4%) for nitrofurantoin. Twelve months postbacteraemia, recurrent bacteraemia rates were 10/105 (9.5%). There were 44 medical device-associated E. coli bacteraemias, and 22 (50%) were urinary catheter associated. There were 10 patients with E. coli bacteraemia caused by procedures, seven genitourinary or biliary tract instrumentation and three postgastrointestinal surgery. CONCLUSION: E. coli bacteraemias related to urosepsis could have been prevented by better empirical treatment and targeted prophylaxis. Urinary catheter quality improvement programmes should contribute to a further reduction. For patients undergoing high-risk urinary or biliary tract procedures or device manipulation, we advocate single-dose amikacin prophylaxis.

PMID- 29463692 TI - Prophylactic Antibiotic Use in COPD and the Potential Anti-Inflammatory Activities of Antibiotics. AB - Antibiotics have previously demonstrated anti-inflammatory properties, and they have been linked to therapeutic benefit in several pulmonary conditions that feature inflammation. Previous research suggests that these anti-inflammatory properties may be beneficial in the treatment of COPD. This review assesses the potential benefit of prophylactic, long-term, and low-dose antibiotic therapy in COPD, and whether any effects seen are anti-inflammatory in nature. Randomized, controlled trials comparing antibiotic therapy with placebo in subjects with stable COPD were evaluated. Twelve trials involving 3,784 participants and a range of antibiotics were included: azithromycin (6 studies, 1,972 participants), clarithromycin (1 study, 67 participants), erythromycin (3 studies, 254 participants), roxithromycin (1 study, 191 participants), and moxifloxacin (2 studies, 1,198 participants). In vitro, in vivo, and ex vivo experimental study designs exploring the mechanisms via which antibiotics may act in subjects with stable COPD were evaluated. Azithromycin and erythromycin showed the greatest effect in subjects with COPD, with evidence suggesting improvement in exacerbation-related outcomes and health status, as measured by the St George Respiratory Questionnaire. An increase in antibiotic resistance was reported in 2 studies. The macrolide class of antibiotics exhibited convincing anti inflammatory properties with relevance to COPD, implicating several pathways as potential mechanisms of action. In conclusion, the therapeutic benefit of macrolide antibiotics in subjects with stable COPD is consistent with anti inflammatory properties, and macrolides should be considered as a potential therapy in COPD. Safety concerns regarding antibiotic resistance need to be addressed before widespread use in clinical practice. PMID- 29463691 TI - Sepsis-Induced T Cell Immunoparalysis: The Ins and Outs of Impaired T Cell Immunity. AB - Sepsis results in a deluge of pro- and anti-inflammatory cytokines, leading to lymphopenia and chronic immunoparalysis. Sepsis-induced long-lasting immunoparalysis is defined, in part, by impaired CD4 and CD8 alphabeta T cell responses in the postseptic environment. The dysfunction in T cell immunity affects naive, effector, and memory T cells and is not restricted to classical alphabeta T cells. Although sepsis-induced severe and transient lymphopenia is a contributory factor to diminished T cell immunity, T cell-intrinsic and extrinsic factors/mechanisms also contribute to impaired T cell function. In this review, we summarize the current knowledge of how sepsis quantitatively and qualitatively impairs CD4 and CD8 T cell immunity of classical and nonclassical T cell subsets and discuss current therapeutic approaches being developed to boost the recovery of T cell immunity postsepsis induction. PMID- 29463693 TI - Content analysis of requests for religious exemptions from a mandatory influenza vaccination program for healthcare personnel. AB - OBJECTIVE: Having failed to achieve adequate influenza vaccination rates among employees through voluntary programmes, healthcare organisations have adopted mandatory ones. Some programmes permit religious exemptions, but little is known about who requests religious objections or why. METHODS: Content analysis of applications for religious exemptions from influenza vaccination at a free standing children's hospital in Cincinnati, Ohio, USA during the 2014-2015 influenza season. RESULTS: Twelve of 15 260 (0.08%) employees submitted applications requesting religious exemptions. Requestors included both clinical and non-clinical employees. All requestors voluntarily identified their religious affiliation, and most were Christian (n=9). Content analysis identified six categories of reasons used to justify an exemption: risks/benefits, ethical/political, lack of direct patient contact, providence, purity and sanctity of life. Individuals articulated reasons in 1-5 (mean 2.6) categories. The most frequently cited category (n=9) was purity; the vaccine and/or its mode of administration were impure, or receiving the vaccine would make the individual impure. Two individuals asserted that the vaccine contained cells derived from aborted human fetuses. Individuals (n=6) also volunteered information supporting the sincerity of their beliefs including distress over previous vaccination and examples of behaviour consistent with their specific objection or their general religious commitment. All requests were approved. CONCLUSIONS: Less than 0.1% of employees requested religious exemptions. Partnering with religious leaders and carefully correcting erroneous information may help address requestors' concerns. PMID- 29463694 TI - Desynchrony between brain and peripheral clocks caused by CK1delta/epsilon disruption in GABA neurons does not lead to adverse metabolic outcomes. AB - Circadian disruption as a result of shift work is associated with adverse metabolic consequences. Internal desynchrony between the phase of the suprachiasmatic nuclei (SCN) and peripheral clocks is widely believed to be a major factor contributing to these adverse consequences, but this hypothesis has never been tested directly. A GABAergic Cre driver combined with conditional casein kinase mutations (Vgat-Cre+CK1deltafl/flepsilonfl/+ ) was used to lengthen the endogenous circadian period in GABAergic neurons, including the SCN, but not in peripheral tissues, to create a Discordant mouse model. These mice had a long (27.4 h) behavioral period to which peripheral clocks entrained in vivo, albeit with an advanced phase (~6 h). Thus, in the absence of environmental timing cues, these mice had internal desynchrony between the SCN and peripheral clocks. Surprisingly, internal desynchrony did not result in obesity in this model. Instead, Discordant mice had reduced body mass compared with Cre-negative controls on regular chow and even when challenged with a high-fat diet. Similarly, internal desynchrony failed to induce glucose intolerance or disrupt body temperature and energy expenditure rhythms. Subsequently, a lighting cycle of 2-h light/23.5-h dark was used to create a similar internal desynchrony state in both genotypes. Under these conditions, Discordant mice maintained their lower body mass relative to controls, suggesting that internal desynchrony did not cause the lowered body mass. Overall, our results indicate that internal desynchrony does not necessarily lead to metabolic derangements and suggest that additional mechanisms contribute to the adverse metabolic consequences observed in circadian disruption protocols. PMID- 29463695 TI - Climate-mediated hybrid zone movement revealed with genomics, museum collection, and simulation modeling. AB - Climate-mediated changes in hybridization will dramatically alter the genetic diversity, adaptive capacity, and evolutionary trajectory of interbreeding species. Our ability to predict the consequences of such changes will be key to future conservation and management decisions. Here we tested through simulations how recent warming (over the course of a 32-y period) is affecting the geographic extent of a climate-mediated developmental threshold implicated in maintaining a butterfly hybrid zone (Papilio glaucus and Papilio canadensis; Lepidoptera: Papilionidae). These simulations predict a 68-km shift of this hybrid zone. To empirically test this prediction, we assessed genetic and phenotypic changes using contemporary and museum collections and document a 40-km northward shift of this hybrid zone. Interactions between the two species appear relatively unchanged during hybrid zone movement. We found no change in the frequency of hybridization, and regions of the genome that experience little to no introgression moved largely in concert with the shifting hybrid zone. Model predictions based on climate scenarios predict this hybrid zone will continue to move northward, but with substantial spatial heterogeneity in the velocity (55 144 km/1 degrees C), shape, and contiguity of movement. Our findings suggest that the presence of nonclimatic barriers (e.g., genetic incompatibilities) and/or nonlinear responses to climatic gradients may preserve species boundaries as the species shift. Further, we show that variation in the geography of hybrid zone movement could result in evolutionary responses that differ for geographically distinct populations spanning hybrid zones, and thus have implications for the conservation and management of genetic diversity. PMID- 29463696 TI - Genetic rescue of lineage-balanced blood cell production reveals a crucial role for STAT3 antiinflammatory activity in hematopoiesis. AB - Blood cell formation must be appropriately maintained throughout life to provide robust immune function, hemostasis, and oxygen delivery to tissues, and to prevent disorders that result from over- or underproduction of critical lineages. Persistent inflammation deregulates hematopoiesis by damaging hematopoietic stem and progenitor cells (HSPCs), leading to elevated myeloid cell output and eventual bone marrow failure. Nonetheless, antiinflammatory mechanisms that protect the hematopoietic system are understudied. The transcriptional regulator STAT3 has myriad roles in HSPC-derived populations and nonhematopoietic tissues, including a potent antiinflammatory function in differentiated myeloid cells. STAT3 antiinflammatory activity is facilitated by STAT3-mediated transcriptional repression of Ube2n, which encodes the E2 ubiquitin-conjugating enzyme Ubc13 involved in proinflammatory signaling. Here we demonstrate a crucial role for STAT3 antiinflammatory activity in preservation of HSPCs and lineage-balanced hematopoiesis. Conditional Stat3 removal from the hematopoietic system led to depletion of the bone marrow lineage- Sca-1+ c-Kit+ CD150+ CD48- HSPC subset (LSK CD150+ CD48- cells), myeloid-skewed hematopoiesis, and accrual of DNA damage in HSPCs. These responses were accompanied by intrinsic transcriptional alterations in HSPCs, including deregulation of inflammatory, survival and developmental pathways. Concomitant Ube2n/Ubc13 deletion from Stat3-deficient hematopoietic cells enabled lineage-balanced hematopoiesis, mitigated depletion of bone marrow LSK CD150+ CD48- cells, alleviated HSPC DNA damage, and corrected a majority of aberrant transcriptional responses. These results indicate an intrinsic protective role for STAT3 in the hematopoietic system, and suggest that this is mediated by STAT3-dependent restraint of excessive proinflammatory signaling via Ubc13 modulation. PMID- 29463697 TI - Membrane protein MHZ3 stabilizes OsEIN2 in rice by interacting with its Nramp like domain. AB - The phytohormone ethylene regulates many aspects of plant growth and development. EIN2 is the central regulator of ethylene signaling, and its turnover is crucial for triggering ethylene responses. Here, we identified a stabilizer of OsEIN2 through analysis of the rice ethylene-response mutant mhz3. Loss-of-function mutations lead to ethylene insensitivity in etiolated rice seedlings. MHZ3 encodes a previously uncharacterized membrane protein localized to the endoplasmic reticulum. Ethylene induces MHZ3 gene and protein expression. Genetically, MHZ3 acts at the OsEIN2 level in the signaling pathway. MHZ3 physically interacts with OsEIN2, and both the N- and C-termini of MHZ3 specifically associate with the OsEIN2 Nramp-like domain. Loss of mhz3 function reduces OsEIN2 abundance and attenuates ethylene-induced OsEIN2 accumulation, whereas MHZ3 overexpression elevates the abundance of both wild-type and mutated OsEIN2 proteins, suggesting that MHZ3 is required for proper accumulation of OsEIN2 protein. The association of MHZ3 with the Nramp-like domain is crucial for OsEIN2 accumulation, demonstrating the significance of the OsEIN2 transmembrane domains in ethylene signaling. Moreover, MHZ3 negatively modulates OsEIN2 ubiquitination, protecting OsEIN2 from proteasome-mediated degradation. Together, these results suggest that ethylene-induced MHZ3 stabilizes OsEIN2 likely by binding to its Nramp-like domain and impeding protein ubiquitination to facilitate ethylene signal transduction. Our findings provide insight into the mechanisms of ethylene signaling. PMID- 29463698 TI - Structural basis and energy landscape for the Ca2+ gating and calmodulation of the Kv7.2 K+ channel. AB - The Kv7.2 (KCNQ2) channel is the principal molecular component of the slow voltage-gated, noninactivating K+ M-current, a key controller of neuronal excitability. To investigate the calmodulin (CaM)-mediated Ca2+ gating of the channel, we used NMR spectroscopy to structurally and dynamically describe the association of helices hA and hB of Kv7.2 with CaM, as a function of Ca2+ concentration. The structures of the CaM/Kv7.2-hAB complex at two different calcification states are reported here. In the presence of a basal cytosolic Ca2+ concentration (10-100 nM), only the N-lobe of CaM is Ca2+-loaded and the complex (representative of the open channel) exhibits collective dynamics on the millisecond time scale toward a low-populated excited state (1.5%) that corresponds to the inactive state of the channel. In response to a chemical or electrical signal, intracellular Ca2+ levels rise up to 1-10 MUM, triggering Ca2+ association with the C-lobe. The associated conformational rearrangement is the key biological signal that shifts populations to the closed/inactive channel. This reorientation affects the C-lobe of CaM and both helices in Kv7.2, allosterically transducing the information from the Ca2+-binding site to the transmembrane region of the channel.

PMID- 29463699 TI - Massive crossover elevation via combination of HEI10 and recq4a recq4b during Arabidopsis meiosis. AB - During meiosis, homologous chromosomes undergo reciprocal crossovers, which generate genetic diversity and underpin classical crop improvement. Meiotic recombination initiates from DNA double-strand breaks (DSBs), which are processed into single-stranded DNA that can invade a homologous chromosome. The resulting joint molecules can ultimately be resolved as crossovers. In Arabidopsis, competing pathways balance the repair of ~100-200 meiotic DSBs into ~10 crossovers per meiosis, with the excess DSBs repaired as noncrossovers. To bias DSB repair toward crossovers, we simultaneously increased dosage of the procrossover E3 ligase gene HEI10 and introduced mutations in the anticrossovers helicase genes RECQ4A and RECQ4B As HEI10 and recq4a recq4b increase interfering and noninterfering crossover pathways, respectively, they combine additively to yield a massive meiotic recombination increase. Interestingly, we also show that increased HEI10 dosage increases crossover coincidence, which indicates an effect on interference. We also show that patterns of interhomolog polymorphism and heterochromatin drive recombination increases distally towards the subtelomeres in both HEI10 and recq4a recq4b backgrounds, while the centromeres remain crossover suppressed. These results provide a genetic framework for engineering meiotic recombination landscapes in plant genomes. PMID- 29463702 TI - Theory of signs and statistical approach to big data in assessing the relevance of clinical biomarkers of inflammation and oxidative stress. AB - Biomarkers are widely used not only as prognostic or diagnostic indicators, or as surrogate markers of disease in clinical trials, but also to formulate theories of pathogenesis. We identify two problems in the use of biomarkers in mechanistic studies. The first problem arises in the case of multifactorial diseases, where different combinations of multiple causes result in patient heterogeneity. The second problem arises when a pathogenic mediator is difficult to measure. This is the case of the oxidative stress (OS) theory of disease, where the causal components are reactive oxygen species (ROS) that have very short half-lives. In this case, it is usual to measure the traces left by the reaction of ROS with biological molecules, rather than the ROS themselves. Borrowing from the philosophical theories of signs, we look at the different facets of biomarkers and discuss their different value and meaning in multifactorial diseases and system medicine to inform their use in patient stratification in personalized medicine. PMID- 29463701 TI - Bone degradation machinery of osteoclasts: An HIV-1 target that contributes to bone loss. AB - Bone deficits are frequent in HIV-1-infected patients. We report here that osteoclasts, the cells specialized in bone resorption, are infected by HIV-1 in vivo in humanized mice and ex vivo in human joint biopsies. In vitro, infection of human osteoclasts occurs at different stages of osteoclastogenesis via cell free viruses and, more efficiently, by transfer from infected T cells. HIV-1 infection markedly enhances adhesion and osteolytic activity of human osteoclasts by modifying the structure and function of the sealing zone, the osteoclast specific bone degradation machinery. Indeed, the sealing zone is broader due to F actin enrichment of its basal units (i.e., the podosomes). The viral protein Nef is involved in all HIV-1-induced effects partly through the activation of Src, a regulator of podosomes and of their assembly as a sealing zone. Supporting these results, Nef-transgenic mice exhibit an increased osteoclast density and bone defects, and osteoclasts derived from these animals display high osteolytic activity. Altogether, our study evidences osteoclasts as host cells for HIV-1 and their pathological contribution to bone disorders induced by this virus, in part via Nef. PMID- 29463703 TI - Defining the sizes of airborne particles that mediate influenza transmission in ferrets. AB - Epidemics and pandemics of influenza are characterized by rapid global spread mediated by non-mutually exclusive transmission modes. The relative significance between contact, droplet, and airborne transmission is yet to be defined, a knowledge gap for implementing evidence-based infection control measures. We devised a transmission chamber that separates virus-laden particles by size and determined the particle sizes mediating transmission of influenza among ferrets through the air. Ferret-to-ferret transmission was mediated by airborne particles larger than 1.5 um, consistent with the quantity and size of virus-laden particles released by the donors. Onward transmission by donors was most efficient before fever onset and may continue for 5 days after inoculation. Multiple virus gene segments enhanced the transmissibility of a swine influenza virus among ferrets by increasing the release of virus-laden particles into the air. We provide direct experimental evidence of influenza transmission via droplets and fine droplet nuclei, albeit at different efficiency.

PMID- 29463705 TI - Controlling of glutamate release by neuregulin3 via inhibiting the assembly of the SNARE complex. AB - Neuregulin3 (NRG3) is a growth factor of the neuregulin (NRG) family and a risk gene of various severe mental illnesses including schizophrenia, bipolar disorders, and major depression. However, the physiological function of NRG3 remains poorly understood. Here we show that loss of Nrg3 in GFAP-Nrg3f/f mice increased glutamatergic transmission, but had no effect on GABAergic transmission. These phenotypes were observed in Nex-Nrg3f/f mice, where Nrg3 was specifically knocked out in pyramidal neurons, indicating that Nrg3 regulates glutamatergic transmission by a cell-autonomous mechanism. Consequently, in the absence of Nrg3 in pyramidal neurons, mutant mice displayed various behavioral deficits related to mental illnesses. We show that the Nrg3 mutation decreased paired-pulse facilitation, increased decay of NMDAR currents when treated with MK801, and increased minimal stimulation-elicited response, providing evidence that the Nrg3 mutation increases glutamate release probability. Notably, Nrg3 is a presynaptic protein that regulates the SNARE-complex assembly. Finally, increased Nrg3 levels, as observed in patients with severe mental illnesses, suppressed glutamatergic transmission. Together, these observations indicate that, unlike the prototype Nrg1, the effect of which is mediated by activating ErbB4 in interneurons, Nrg3 is critical in controlling glutamatergic transmission by regulating the SNARE complex at the presynaptic terminals, identifying a function of Nrg3 and revealing a pathophysiological mechanism for hypofunction of the glutamatergic pathway in Nrg3-related severe mental illnesses. PMID- 29463706 TI - MotAB-like machinery drives the movement of MreB filaments during bacterial gliding motility. AB - MreB is a bacterial actin that is important for cell shape and cell wall biosynthesis in many bacterial species. MreB also plays crucial roles in Myxococcus xanthus gliding motility, but the underlying mechanism remains unknown. Here we tracked the dynamics of single MreB particles in M. xanthus using single-particle tracking photoactivated localization microscopy. We found that a subpopulation of MreB particles moves rapidly along helical trajectories, similar to the movements of the MotAB-like gliding motors. The rapid MreB motion was stalled in the mutants that carried truncated gliding motors. Remarkably, M. xanthus MreB moves one to two orders of magnitude faster than its homologs that move along with the cell wall synthesis machinery in Bacillus subtilis and Escherichia coli, and this rapid movement was not affected by the inhibitors of cell wall biosynthesis. Our results show that in M. xanthus, MreB provides a scaffold for the gliding motors while the gliding machinery drives the movement of MreB filaments, analogous to the interdependent movements of myosin motors and actin in eukaryotic cells. PMID- 29463707 TI - Robo and Ror function in a common receptor complex to regulate Wnt-mediated neurite outgrowth in Caenorhabditis elegans. AB - Growing axons are exposed to various guidance cues en route to their targets, but the mechanisms that govern the response of growth cones to combinations of signals remain largely elusive. Here, we found that the sole Robo receptor, SAX 3, in Caenorhabditis elegans functions as a coreceptor for Wnt/CWN-2 molecules. SAX-3 binds to Wnt/CWN-2 and facilitates the membrane recruitment of CWN-2. SAX-3 forms a complex with the Ror/CAM-1 receptor and its downstream effector Dsh/DSH 1, promoting signal transduction from Wnt to Dsh. sax-3 functions in Wnt responsive cells and the SAX-3 receptor is restricted to the side of the cell from which the neurite is extended. DSH-1 has a similar asymmetric distribution, which is disrupted by sax-3 mutation. Taking these results together, we propose that Robo receptor can function as a Wnt coreceptor to regulate Wnt-mediated biological processes in vivo. PMID- 29463708 TI - Environmental enrichment and exercise are better than social enrichment to reduce memory deficits in amyloid beta neurotoxicity. AB - Recently, nongenetic animal models to study the onset and development of Alzheimer's disease (AD) have appeared, such as the intrahippocampal infusion of peptides present in Alzheimer amyloid plaques [i.e., amyloid-beta (Abeta)]. Nonpharmacological approaches to AD treatment also have been advanced recently, which involve combinations of behavioral interventions whose specific effects are often difficult to determine. Here we isolate the neuroprotective effects of three of these interventions-environmental enrichment (EE), anaerobic physical exercise (AnPE), and social enrichment (SE)-on Abeta-induced oxidative stress and on impairments in learning and memory induced by Abeta. Wistar rats were submitted to 8 wk of EE, AnPE, or SE, followed by Abeta infusion in the dorsal hippocampus. Short-term memory (STM) and long-term memory (LTM) of object recognition (OR) and social recognition (SR) were evaluated. Biochemical assays determined hippocampal oxidative status: reactive oxygen species, lipid peroxidation by thiobarbituric acid reactive substance (TBARS) test, and total antioxidant capacity by ferric reducing/antioxidant power (FRAP), as well as acetylcholinesterase activity. Abeta infusion resulted in memory deficits and hippocampal oxidative damage. EE and AnPE prevented all memory deficits (STM and LTM of OR and SR) and lipid peroxidation (i.e., TBARS). SE prevented only the SR memory deficits and the decrease of total antioxidant capacity decrease (i.e., FRAP). Traditionally, findings obtained with EE protocols do not allow discrimination of the roles of the three individual factors involved. Here we demonstrate that EE and physical exercise have better neuroprotective effects than SE in memory deficits related to Abeta neurotoxicity in the AD model tested. PMID- 29463709 TI - Identification of the YEATS domain of GAS41 as a pH-dependent reader of histone succinylation. AB - Lysine succinylation is a newly discovered posttranslational modification with distinctive physical properties. However, to date rarely have studies reported effectors capable of interpreting this modification on histones. Following our previous study of SIRT5 as an eraser of succinyl-lysine (Ksuc), here we identified the GAS41 YEATS domain as a reader of Ksuc on histones. Biochemical studies showed that the GAS41 YEATS domain presents significant binding affinity toward H3K122suc upon a protonated histidine residue. Furthermore, cellular studies showed that GAS41 had prominent interaction with H3K122suc on histones and also demonstrated the coenrichment of GAS41 and H3K122suc on the p21 promoter. To investigate the binding mechanism, we solved the crystal structure of the YEATS domain of Yaf9, the GAS41 homolog, in complex with an H3K122suc peptide that demonstrated the presence of a salt bridge formed when a protonated histidine residue (His39) recognizes the carboxyl terminal of the succinyl group. We also solved the apo structure of GAS41 YEATS domain, in which the conserved His43 residue superimposes well with His39 in the Yaf9 structure. Our findings identified a reader of succinyl-lysine, and the binding mechanism will provide insight into the development of specific regulators targeting GAS41. PMID- 29463711 TI - Demographic compensation does not rescue populations at a trailing range edge. AB - Species' geographic ranges and climatic niches are likely to be increasingly mismatched due to rapid climate change. If a species' range and niche are out of equilibrium, then population performance should decrease from high-latitude "leading" range edges, where populations are expanding into recently ameliorated habitats, to low-latitude "trailing" range edges, where populations are contracting from newly unsuitable areas. Demographic compensation is a phenomenon whereby declines in some vital rates are offset by increases in others across time or space. In theory, demographic compensation could increase the range of environments over which populations can succeed and forestall range contraction at trailing edges. An outstanding question is whether range limits and range contractions reflect inadequate demographic compensation across environmental gradients, causing population declines at range edges. We collected demographic data from 32 populations of the scarlet monkeyflower (Erythranthe cardinalis) spanning 11 degrees of latitude in western North America and used integral projection models to evaluate population dynamics and assess demographic compensation across the species' range. During the 5-y study period, which included multiple years of severe drought and warming, population growth rates decreased from north to south, consistent with leading-trailing dynamics. Southern populations at the trailing range edge declined due to reduced survival, growth, and recruitment, despite compensatory increases in reproduction and faster life-history characteristics. These results suggest that demographic compensation may only delay population collapse without the return of more favorable conditions or the contribution of other buffering mechanisms such as evolutionary rescue. PMID- 29463710 TI - Optically functional isoxanthopterin crystals in the mirrored eyes of decapod crustaceans. AB - The eyes of some aquatic animals form images through reflective optics. Shrimp, lobsters, crayfish, and prawns possess reflecting superposition compound eyes, composed of thousands of square-faceted eye units (ommatidia). Mirrors in the upper part of the eye (the distal mirror) reflect light collected from many ommatidia onto the photosensitive elements of the retina, the rhabdoms. A second reflector, the tapetum, underlying the retina, back-scatters dispersed light onto the rhabdoms. Using microCT and cryo-SEM imaging accompanied by in situ micro-X ray diffraction and micro-Raman spectroscopy, we investigated the hierarchical organization and materials properties of the reflective systems at high resolution and under close-to-physiological conditions. We show that the distal mirror consists of three or four layers of plate-like nanocrystals. The tapetum is a diffuse reflector composed of hollow nanoparticles constructed from concentric lamellae of crystals. Isoxanthopterin, a pteridine analog of guanine, forms both the reflectors in the distal mirror and in the tapetum. The crystal structure of isoxanthopterin was determined from crystal-structure prediction calculations and verified by comparison with experimental X-ray diffraction. The extended hydrogen-bonded layers of the molecules result in an extremely high calculated refractive index in the H-bonded plane, n = 1.96, which makes isoxanthopterin crystals an ideal reflecting material. The crystal structure of isoxanthopterin, together with a detailed knowledge of the reflector superstructures, provide a rationalization of the reflective optics of the crustacean eye. PMID- 29463712 TI - Fundamental limits on dynamic inference from single-cell snapshots. AB - Single-cell expression profiling reveals the molecular states of individual cells with unprecedented detail. Because these methods destroy cells in the process of analysis, they cannot measure how gene expression changes over time. However, some information on dynamics is present in the data: the continuum of molecular states in the population can reflect the trajectory of a typical cell. Many methods for extracting single-cell dynamics from population data have been proposed. However, all such attempts face a common limitation: for any measured distribution of cell states, there are multiple dynamics that could give rise to it, and by extension, multiple possibilities for underlying mechanisms of gene regulation. Here, we describe the aspects of gene expression dynamics that cannot be inferred from a static snapshot alone and identify assumptions necessary to constrain a unique solution for cell dynamics from static snapshots. We translate these constraints into a practical algorithmic approach, population balance analysis (PBA), which makes use of a method from spectral graph theory to solve a class of high-dimensional differential equations. We use simulations to show the strengths and limitations of PBA, and then apply it to single-cell profiles of hematopoietic progenitor cells (HPCs). Cell state predictions from this analysis agree with HPC fate assays reported in several papers over the past two decades. By highlighting the fundamental limits on dynamic inference faced by any method, our framework provides a rigorous basis for dynamic interpretation of a gene expression continuum and clarifies best experimental designs for trajectory reconstruction from static snapshot measurements. PMID- 29463713 TI - Substrate binding to BamD triggers a conformational change in BamA to control membrane insertion. AB - The beta-barrel assembly machine (Bam) complex folds and inserts integral membrane proteins into the outer membrane of Gram-negative bacteria. The two essential components of the complex, BamA and BamD, both interact with substrates, but how the two coordinate with each other during assembly is not clear. To elucidate aspects of this process we slowed the assembly of an essential beta-barrel substrate of the Bam complex, LptD, by changing a conserved residue near the C terminus. This defective substrate is recruited to the Bam complex via BamD but is unable to integrate into the membrane efficiently. Changes in the extracellular loops of BamA partially restore assembly kinetics, implying that BamA fails to engage this defective substrate. We conclude that substrate binding to BamD activates BamA by regulating extracellular loop interactions for folding and membrane integration.

PMID- 29463714 TI - Carbon monoxide protects the kidney through the central circadian clock and CD39. AB - Ischemia reperfusion injury (IRI) is the predominant tissue insult associated with organ transplantation. Treatment with carbon monoxide (CO) modulates the innate immune response associated with IRI and accelerates tissue recovery. The mechanism has been primarily descriptive and ascribed to the ability of CO to influence inflammation, cell death, and repair. In a model of bilateral kidney IRI in mice, we elucidate an intricate relationship between CO and purinergic signaling involving increased CD39 ectonucleotidase expression, decreased expression of Adora1, with concomitant increased expression of Adora2a/2b. This response is linked to a >20-fold increase in expression of the circadian rhythm protein Period 2 (Per2) and a fivefold increase in serum erythropoietin (EPO), both of which contribute to abrogation of kidney IRI. CO is ineffective against IRI in Cd39-/- and Per2-/- mice or in the presence of a neutralizing antibody to EPO. Collectively, these data elucidate a cellular signaling mechanism whereby CO modulates purinergic responses and circadian rhythm to protect against injury. Moreover, these effects involve CD39- and adenosinergic-dependent stabilization of Per2. As CO also increases serum EPO levels in human volunteers, these findings continue to support therapeutic use of CO to treat IRI in association with organ transplantation, stroke, and myocardial infarction. PMID- 29463716 TI - The timescale of early land plant evolution. AB - Establishing the timescale of early land plant evolution is essential for testing hypotheses on the coevolution of land plants and Earth's System. The sparseness of early land plant megafossils and stratigraphic controls on their distribution make the fossil record an unreliable guide, leaving only the molecular clock. However, the application of molecular clock methodology is challenged by the current impasse in attempts to resolve the evolutionary relationships among the living bryophytes and tracheophytes. Here, we establish a timescale for early land plant evolution that integrates over topological uncertainty by exploring the impact of competing hypotheses on bryophyte-tracheophyte relationships, among other variables, on divergence time estimation. We codify 37 fossil calibrations for Viridiplantae following best practice. We apply these calibrations in a Bayesian relaxed molecular clock analysis of a phylogenomic dataset encompassing the diversity of Embryophyta and their relatives within Viridiplantae. Topology and dataset sizes have little impact on age estimates, with greater differences among alternative clock models and calibration strategies. For all analyses, a Cambrian origin of Embryophyta is recovered with highest probability. The estimated ages for crown tracheophytes range from Late Ordovician to late Silurian. This timescale implies an early establishment of terrestrial ecosystems by land plants that is in close accord with recent estimates for the origin of terrestrial animal lineages. Biogeochemical models that are constrained by the fossil record of early land plants, or attempt to explain their impact, must consider the implications of a much earlier, middle Cambrian-Early Ordovician, origin. PMID- 29463717 TI - Sarcomeric perturbations of myosin motors lead to dilated cardiomyopathy in genetically modified MYL2 mice. AB - Dilated cardiomyopathy (DCM) is a devastating heart disease that affects about 1 million people in the United States, but the underlying mechanisms remain poorly understood. In this study, we aimed to determine the biomechanical and structural causes of DCM in transgenic mice carrying a novel mutation in the MYL2 gene, encoding the cardiac myosin regulatory light chain. Transgenic D94A (aspartic acid-to-alanine) mice were created and investigated by echocardiography and invasive hemodynamic and molecular structural and functional assessments. Consistent with the DCM phenotype, a significant reduction of the ejection fraction (EF) was observed in ~5- and ~12-mo-old male and female D94A lines compared with respective WT controls. Younger male D94A mice showed a more pronounced left ventricular (LV) chamber dilation compared with female counterparts, but both sexes of D94A lines developed DCM by 12 mo of age. The hypocontractile activity of D94A myosin motors resulted in the rightward shift of the force-pCa dependence and decreased actin-activated myosin ATPase activity. Consistent with a decreased Ca2+ sensitivity of contractile force, a small-angle X-ray diffraction study, performed in D94A fibers at submaximal Ca2+ concentrations, revealed repositioning of the D94A cross-bridge mass toward the thick-filament backbone supporting the hypocontractile state of D94A myosin motors. Our data suggest that structural perturbations at the level of sarcomeres result in aberrant cardiomyocyte cytoarchitecture and lead to LV chamber dilation and decreased EF, manifesting in systolic dysfunction of D94A hearts. The D94A induced development of DCM in mice closely follows the clinical phenotype and suggests that MYL2 may serve as a new therapeutic target for dilated cardiomyopathy. PMID- 29463718 TI - Structure of full-length human TRPM4. AB - Transient receptor potential melastatin subfamily member 4 (TRPM4) is a widely distributed, calcium-activated, monovalent-selective cation channel. Mutations in human TRPM4 (hTRPM4) result in progressive familial heart block. Here, we report the electron cryomicroscopy structure of hTRPM4 in a closed, Na+-bound, apo state at pH 7.5 to an overall resolution of 3.7 A. Five partially hydrated sodium ions are proposed to occupy the center of the conduction pore and the entrance to the coiled-coil domain. We identify an upper gate in the selectivity filter and a lower gate at the entrance to the cytoplasmic coiled-coil domain. Intramolecular interactions exist between the TRP domain and the S4-S5 linker, N-terminal domain, and N and C termini. Finally, we identify aromatic interactions via pi-pi bonds and cation-pi bonds, glycosylation at an N-linked extracellular site, a pore-loop disulfide bond, and 24 lipid binding sites. We compare and contrast this structure with other TRP channels and discuss potential mechanisms of regulation and gating of human full-length TRPM4. PMID- 29463719 TI - STED nanoscopy of the centrosome linker reveals a CEP68-organized, periodic rootletin network anchored to a C-Nap1 ring at centrioles. AB - The centrosome linker proteins C-Nap1, rootletin, and CEP68 connect the two centrosomes of a cell during interphase into one microtubule-organizing center. This coupling is important for cell migration, cilia formation, and timing of mitotic spindle formation. Very little is known about the structure of the centrosome linker. Here, we used stimulated emission depletion (STED) microscopy to show that each C-Nap1 ring at the proximal end of the two centrioles organizes a rootletin ring and, in addition, multiple rootletin/CEP68 fibers. Rootletin/CEP68 fibers originating from the two centrosomes form a web-like, interdigitating network, explaining the flexible nature of the centrosome linker. The rootletin/CEP68 filaments are repetitive and highly ordered. Staggered rootletin molecules (N-to-N and C-to-C) within the filaments are 75 nm apart. Rootletin binds CEP68 via its C-terminal spectrin repeat-containing region in 75 nm intervals. The N-to-C distance of two rootletin molecules is ~35 to 40 nm, leading to an estimated minimal rootletin length of ~110 nm. CEP68 is important in forming rootletin filaments that branch off centrioles and to modulate the thickness of rootletin fibers. Thus, the centrosome linker consists of a vast network of repeating rootletin units with C-Nap1 as ring organizer and CEP68 as filament modulator. PMID- 29463721 TI - Fast flow-based algorithm for creating density-equalizing map projections. AB - Cartograms are maps that rescale geographic regions (e.g., countries, districts) such that their areas are proportional to quantitative demographic data (e.g., population size, gross domestic product). Unlike conventional bar or pie charts, cartograms can represent correctly which regions share common borders, resulting in insightful visualizations that can be the basis for further spatial statistical analysis. Computer programs can assist data scientists in preparing cartograms, but developing an algorithm that can quickly transform every coordinate on the map (including points that are not exactly on a border) while generating recognizable images has remained a challenge. Methods that translate the cartographic deformations into physics-inspired equations of motion have become popular, but solving these equations with sufficient accuracy can still take several minutes on current hardware. Here we introduce a flow-based algorithm whose equations of motion are numerically easier to solve compared with previous methods. The equations allow straightforward parallelization so that the calculation takes only a few seconds even for complex and detailed input. Despite the speedup, the proposed algorithm still keeps the advantages of previous techniques: With comparable quantitative measures of shape distortion, it accurately scales all areas, correctly fits the regions together, and generates a map projection for every point. We demonstrate the use of our algorithm with applications to the 2016 US election results, the gross domestic products of Indian states and Chinese provinces, and the spatial distribution of deaths in the London borough of Kensington and Chelsea between 2011 and 2014. PMID- 29463720 TI - Gi- and Gs-coupled GPCRs show different modes of G-protein binding. AB - More than two decades ago, the activation mechanism for the membrane-bound photoreceptor and prototypical G protein-coupled receptor (GPCR) rhodopsin was uncovered. Upon light-induced changes in ligand-receptor interaction, movement of specific transmembrane helices within the receptor opens a crevice at the cytoplasmic surface, allowing for coupling of heterotrimeric guanine nucleotide binding proteins (G proteins). The general features of this activation mechanism are conserved across the GPCR superfamily. Nevertheless, GPCRs have selectivity for distinct G-protein family members, but the mechanism of selectivity remains elusive. Structures of GPCRs in complex with the stimulatory G protein, Gs, and an accessory nanobody to stabilize the complex have been reported, providing information on the intermolecular interactions. However, to reveal the structural selectivity filters, it will be necessary to determine GPCR-G protein structures involving other G-protein subtypes. In addition, it is important to obtain structures in the absence of a nanobody that may influence the structure. Here, we present a model for a rhodopsin-G protein complex derived from intermolecular distance constraints between the activated receptor and the inhibitory G protein, Gi, using electron paramagnetic resonance spectroscopy and spin-labeling methodologies. Molecular dynamics simulations demonstrated the overall stability of the modeled complex. In the rhodopsin-Gi complex, Gi engages rhodopsin in a manner distinct from previous GPCR-Gs structures, providing insight into specificity determinants. PMID- 29463723 TI - Rainfall statistics, stationarity, and climate change. AB - There is a growing research interest in the detection of changes in hydrologic and climatic time series. Stationarity can be assessed using the autocorrelation function, but this is not yet common practice in hydrology and climate. Here, we use a global land-based gridded annual precipitation (hereafter P) database (1940 2009) and find that the lag 1 autocorrelation coefficient is statistically significant at around 14% of the global land surface, implying nonstationary behavior (90% confidence). In contrast, around 76% of the global land surface shows little or no change, implying stationary behavior. We use these results to assess change in the observed P over the most recent decade of the database. We find that the changes for most (84%) grid boxes are within the plausible bounds of no significant change at the 90% CI. The results emphasize the importance of adequately accounting for natural variability when assessing change. PMID- 29463722 TI - Tracking the route of molecular oxygen in O2-tolerant membrane-bound [NiFe] hydrogenase. AB - [NiFe] hydrogenases catalyze the reversible splitting of H2 into protons and electrons at a deeply buried active site. The catalytic center can be accessed by gas molecules through a hydrophobic tunnel network. While most [NiFe] hydrogenases are inactivated by O2, a small subgroup, including the membrane bound [NiFe] hydrogenase (MBH) of Ralstonia eutropha, is able to overcome aerobic inactivation by catalytic reduction of O2 to water. This O2 tolerance relies on a special [4Fe3S] cluster that is capable of releasing two electrons upon O2 attack. Here, the O2 accessibility of the MBH gas tunnel network has been probed experimentally using a "soak-and-freeze" derivatization method, accompanied by protein X-ray crystallography and computational studies. This combined approach revealed several sites of O2 molecules within a hydrophobic tunnel network leading, via two tunnel entrances, to the catalytic center of MBH. The corresponding site occupancies were related to the O2 concentrations used for MBH crystal derivatization. The examination of the O2-derivatized data furthermore uncovered two unexpected structural alterations at the [4Fe3S] cluster, which might be related to the O2 tolerance of the enzyme. PMID- 29463724 TI - Distinct sets of tethering complexes, SNARE complexes, and Rab GTPases mediate membrane fusion at the vacuole in Arabidopsis. AB - Membrane trafficking plays pivotal roles in various cellular activities and higher-order functions of eukaryotes and requires tethering factors to mediate contact between transport intermediates and target membranes. Two evolutionarily conserved tethering complexes, homotypic fusion and protein sorting (HOPS) and class C core vacuole/endosome tethering (CORVET), are known to act in endosomal/vacuolar transport in yeast and animals. Both complexes share a core subcomplex consisting of Vps11, Vps18, Vps16, and Vps33, and in addition to this core, HOPS contains Vps39 and Vps41, whereas CORVET contains Vps3 and Vps8. HOPS and CORVET subunits are also conserved in the model plant Arabidopsis. However, vacuolar trafficking in plants occurs through multiple unique transport pathways, and how these conserved tethering complexes mediate endosomal/vacuolar transport in plants has remained elusive. In this study, we investigated the functions of VPS18, VPS3, and VPS39, which are core complex, CORVET-specific, and HOPS specific subunits, respectively. Impairment of these tethering proteins resulted in embryonic lethality, distinctly altering vacuolar morphology and perturbing transport of a vacuolar membrane protein. CORVET interacted with canonical RAB5 and a plant-specific R-soluble NSF attachment protein receptor (SNARE), VAMP727, which mediates fusion between endosomes and the vacuole, whereas HOPS interacted with RAB7 and another R-SNARE, VAMP713, which likely mediates homotypic vacuolar fusion. These results indicate that CORVET and HOPS act in distinct vacuolar trafficking pathways in plant cells, unlike those of nonplant systems that involve sequential action of these tethering complexes during vacuolar/lysosomal trafficking. These results highlight a unique diversification of vacuolar/lysosomal transport that arose during plant evolution, using evolutionarily conserved tethering components. PMID- 29463725 TI - Tim-3 co-stimulation promotes short-lived effector T cells, restricts memory precursors, and is dispensable for T cell exhaustion. AB - Tim-3 is highly expressed on a subset of T cells during T cell exhaustion in settings of chronic viral infection and tumors. Using lymphocytic choriomeningitis virus (LCMV) Clone 13, a model for chronic infection, we found that Tim-3 was neither necessary nor sufficient for the development of T cell exhaustion. Nonetheless, expression of Tim-3 was sufficient to drive resistance to PD-L1 blockade therapy during chronic infection. Strikingly, expression of Tim 3 promoted the development of short-lived effector T cells, at the expense of memory precursor development, after acute LCMV infection. These effects were accompanied by increased Akt/mTOR signaling in T cells expressing endogenous or ectopic Tim-3. Conversely, Akt/mTOR signaling was reduced in effector T cells from Tim-3-deficient mice. Thus, Tim-3 is essential for optimal effector T cell responses, and may also contribute to exhaustion by restricting the development of long-lived memory T cells. Taken together, our results suggest that Tim-3 is actually more similar to costimulatory receptors that are up-regulated after T cell activation than to a dominant inhibitory protein like PD-1. These findings have significant implications for the development of anti-Tim-3 antibodies as therapeutic agents. PMID- 29463726 TI - Structures of the prefusion form of measles virus fusion protein in complex with inhibitors. AB - Measles virus (MeV), a major cause of childhood morbidity and mortality, is highly immunotropic and one of the most contagious pathogens. MeV may establish, albeit rarely, persistent infection in the central nervous system, causing fatal and intractable neurodegenerative diseases such as subacute sclerosing panencephalitis and measles inclusion body encephalitis. Recent studies have suggested that particular substitutions in the MeV fusion (F) protein are involved in the pathogenesis by destabilizing the F protein and endowing it with hyperfusogenicity. Here we show the crystal structures of the prefusion MeV-F alone and in complex with the small compound AS-48 or a fusion inhibitor peptide. Notably, these independently developed inhibitors bind the same hydrophobic pocket located at the region connecting the head and stalk of MeV-F, where a number of substitutions in MeV isolates from neurodegenerative diseases are also localized. Since these inhibitors could suppress membrane fusion mediated by most of the hyperfusogenic MeV-F mutants, the development of more effective inhibitors based on the structures may be warranted to treat MeV-induced neurodegenerative diseases.

PMID- 29463727 TI - The secreted metabolome of Streptomyces chartreusis and implications for bacterial chemistry. AB - Actinomycetes are known for producing diverse secondary metabolites. Combining genomics with untargeted data-dependent tandem MS and molecular networking, we characterized the secreted metabolome of the tunicamycin producer Streptomyces chartreusis NRRL 3882. The genome harbors 128 predicted biosynthetic gene clusters. We detected >1,000 distinct secreted metabolites in culture supernatants, only 22 of which were identified based on standards and public spectral libraries. S. chartreusis adapts the secreted metabolome to cultivation conditions. A number of metabolites are produced iron dependently, among them 17 desferrioxamine siderophores aiding in iron acquisition. Eight previously unknown members of this long-known compound class are described. A single desferrioxamine synthesis gene cluster was detected in the genome, yet different sets of desferrioxamines are produced in different media. Additionally, a polyether ionophore, differentially produced by the calcimycin biosynthesis cluster, was discovered. This illustrates that metabolite output of a single biosynthetic machine can be exquisitely regulated not only with regard to product quantity but also with regard to product range. Compared with chemically defined medium, in complex medium, total metabolite abundance was higher, structural diversity greater, and the average molecular weight almost doubled. Tunicamycins, for example, were only produced in complex medium. Extrapolating from this study, we anticipate that the larger part of bacterial chemistry, including chemical structures, ecological functions, and pharmacological potential, is yet to be uncovered. PMID- 29463729 TI - NLR surveillance of essential SEC-9 SNARE proteins induces programmed cell death upon allorecognition in filamentous fungi. AB - In plants and metazoans, intracellular receptors that belong to the NOD-like receptor (NLR) family are major contributors to innate immunity. Filamentous fungal genomes contain large repertoires of genes encoding for proteins with similar architecture to plant and animal NLRs with mostly unknown function. Here, we identify and molecularly characterize patatin-like phospholipase-1 (PLP-1), an NLR-like protein containing an N-terminal patatin-like phospholipase domain, a nucleotide-binding domain (NBD), and a C-terminal tetratricopeptide repeat (TPR) domain. PLP-1 guards the essential SNARE protein SEC-9; genetic differences at plp-1 and sec-9 function to trigger allorecognition and cell death in two distantly related fungal species, Neurospora crassa and Podospora anserina Analyses of Neurospora population samples revealed that plp-1 and sec-9 alleles are highly polymorphic, segregate into discrete haplotypes, and show transspecies polymorphism. Upon fusion between cells bearing incompatible sec-9 and plp-1 alleles, allorecognition and cell death are induced, which are dependent upon physical interaction between SEC-9 and PLP-1. The central NBD and patatin-like phospholipase activity of PLP-1 are essential for allorecognition and cell death, while the TPR domain and the polymorphic SNARE domain of SEC-9 function in conferring allelic specificity. Our data indicate that fungal NLR-like proteins function similar to NLR immune receptors in plants and animals, showing that NLRs are major contributors to innate immunity in plants and animals and for allorecognition in fungi. PMID- 29463730 TI - Long-term potentiation expands information content of hippocampal dentate gyrus synapses. AB - An approach combining signal detection theory and precise 3D reconstructions from serial section electron microscopy (3DEM) was used to investigate synaptic plasticity and information storage capacity at medial perforant path synapses in adult hippocampal dentate gyrus in vivo. Induction of long-term potentiation (LTP) markedly increased the frequencies of both small and large spines measured 30 minutes later. This bidirectional expansion resulted in heterosynaptic counterbalancing of total synaptic area per unit length of granule cell dendrite. Control hemispheres exhibited 6.5 distinct spine sizes for 2.7 bits of storage capacity while LTP resulted in 12.9 distinct spine sizes (3.7 bits). In contrast, control hippocampal CA1 synapses exhibited 4.7 bits with much greater synaptic precision than either control or potentiated dentate gyrus synapses. Thus, synaptic plasticity altered total capacity, yet hippocampal subregions differed dramatically in their synaptic information storage capacity, reflecting their diverse functions and activation histories. PMID- 29463731 TI - Gibberellin DELLA signaling targets the retromer complex to redirect protein trafficking to the plasma membrane. AB - The plant hormone gibberellic acid (GA) is a crucial regulator of growth and development. The main paradigm of GA signaling puts forward transcriptional regulation via the degradation of DELLA transcriptional repressors. GA has also been shown to regulate tropic responses by modulation of the plasma membrane incidence of PIN auxin transporters by an unclear mechanism. Here we uncovered the cellular and molecular mechanisms by which GA redirects protein trafficking and thus regulates cell surface functionality. Photoconvertible reporters revealed that GA balances the protein traffic between the vacuole degradation route and recycling back to the cell surface. Low GA levels promote vacuolar delivery and degradation of multiple cargos, including PIN proteins, whereas high GA levels promote their recycling to the plasma membrane. This GA effect requires components of the retromer complex, such as Sorting Nexin 1 (SNX1) and its interacting, microtubule (MT)-associated protein, the Cytoplasmic Linker Associated Protein (CLASP1). Accordingly, GA regulates the subcellular distribution of SNX1 and CLASP1, and the intact MT cytoskeleton is essential for the GA effect on trafficking. This GA cellular action occurs through DELLA proteins that regulate the MT and retromer presumably via their interaction partners Prefoldins (PFDs). Our study identified a branching of the GA signaling pathway at the level of DELLA proteins, which, in parallel to regulating transcription, also target by a nontranscriptional mechanism the retromer complex acting at the intersection of the degradation and recycling trafficking routes. By this mechanism, GA can redirect receptors and transporters to the cell surface, thus coregulating multiple processes, including PIN-dependent auxin fluxes during tropic responses.

AB - Oligonucleotide (oligo)-based FISH has emerged as an important tool for the study of chromosome organization and gene expression and has been empowered by the commercial availability of highly complex pools of oligos. However, a dedicated bioinformatic design utility has yet to be created specifically for the purpose of identifying optimal oligo FISH probe sequences on the genome-wide scale. Here, we introduce OligoMiner, a rapid and robust computational pipeline for the genome scale design of oligo FISH probes that affords the scientist exact control over the parameters of each probe. Our streamlined method uses standard bioinformatic file formats, allowing users to seamlessly integrate new and existing utilities into the pipeline as desired, and introduces a method for evaluating the specificity of each probe molecule that connects simulated hybridization energetics to rapidly generated sequence alignments using supervised machine learning. We demonstrate the scalability of our approach by performing genome scale probe discovery in numerous model organism genomes and showcase the performance of the resulting probes with diffraction-limited and single-molecule superresolution imaging of chromosomal and RNA targets. We anticipate that this pipeline will make the FISH probe design process much more accessible and will more broadly facilitate the design of pools of hybridization probes for a variety of applications.

AB - Pulmonary alveolar type I (AT1) cells cover more than 95% of alveolar surface and are essential for the air-blood barrier function of lungs. AT1 cells have been shown to retain developmental plasticity during alveolar regeneration. However, the development and heterogeneity of AT1 cells remain largely unknown. Here, we conducted a single-cell RNA-seq analysis to characterize postnatal AT1 cell development and identified insulin-like growth factor-binding protein 2 (Igfbp2) as a genetic marker specifically expressed in postnatal AT1 cells. The portion of AT1 cells expressing Igfbp2 increases during alveologenesis and in post pneumonectomy (PNX) newly formed alveoli. We found that the adult AT1 cell population contains both Hopx+Igfbp2+ and Hopx+Igfbp2- AT1 cells, which have distinct cell fates during alveolar regeneration. Using an Igfbp2-CreER mouse model, we demonstrate that Hopx+Igfbp2+ AT1 cells represent terminally differentiated AT1 cells that are not able to transdifferentiate into AT2 cells during post-PNX alveolar regeneration. Our study provides tools and insights that will guide future investigations into the molecular and cellular mechanism or mechanisms underlying AT1 cell fate during lung development and regeneration.

A key result of this tension is that words acquire novel senses over time. However, the cognitive processes that underlie the historical emergence of new word senses are poorly understood. Here, we present a computational framework that formalizes competing views of how new senses of a word might emerge by attaching to existing senses of the word. We test the ability of the models to predict the temporal order in which the senses of individual words have emerged, using an historical lexicon of English spanning the past millennium. Our findings suggest that word senses emerge in predictable ways, following an historical path that reflects cognitive efficiency, predominantly through a process of nearest neighbor chaining. Our work contributes a formal account of the generative processes that underlie lexical evolution.

PMID- 29463739 TI - Synthetic addiction extends the productive life time of engineered Escherichia coli populations. AB - Bio-production of chemicals is an important driver of the societal transition toward sustainability. However, fermentations with heavily engineered production organisms can be challenging to scale to industrial volumes. Such fermentations are subject to evolutionary pressures that select for a wide range of genetic variants that disrupt the biosynthetic capacity of the engineered organism. Synthetic product addiction that couples high-yield production of a desired metabolite to expression of nonconditionally essential genes could offer a solution to this problem by selectively favoring cells with biosynthetic capacity in the population without constraining the medium. We constructed such synthetic product addiction by controlling the expression of two nonconditionally essential genes with a mevalonic acid biosensor. The product-addicted production organism retained high-yield mevalonic acid production through 95 generations of cultivation, corresponding to the number of cell generations required for >200-m3 industrial-scale production, at which time the nonaddicted strain completely abolished production. Using deep DNA sequencing, we find that the product addicted populations do not accumulate genetic variants that compromise biosynthetic capacity, highlighting how synthetic networks can be designed to control genetic population heterogeneity. Such synthetic redesign of evolutionary forces with endogenous processes may be a promising concept for realizing complex cellular designs required for sustainable bio-manufacturing. PMID- 29463741 TI - Transcriptional factor ICER promotes glutaminolysis and the generation of Th17 cells. AB - Glutaminolysis is a well-known source of energy for effector T cells but its contribution to each T cell subset and the mechanisms which are responsible for the control of involved metabolic enzymes are not fully understood. We report that Th17 but not Th1, Th2, or Treg cell induction in vitro depends on glutaminolysis and the up-regulation of glutaminase 1 (Gls1), the first enzyme in the glutaminolysis pathway. Both pharmacological and siRNA-based selective inhibition of Gls1 reduced in vitro Th17 differentiation and reduced the CD3/TCR mediated increase of the mammalian target of rapamycin complex 1 activity. Treatment of mice with a Gls1 inhibitor ameliorated experimental autoimmune encephalomyelitis. Furthermore, RAG1-deficient mice that received Gls1-shRNA transfected 2D2 T cells had reduced experimental autoimmune encephalomyelitis scores compared with those that received control-shRNA-treated cells. Next we found that T cells deficient in inducible cAMP early repressor (ICER), a transcriptional factor known to promote Th17 differentiation, display reduced activity of oxidative phosphorylation rates in the presence of glutamine and reduced Gls1 expression, both of which could be restored by ICER overexpression. Finally, we demonstrate that ICER binds to the gls1 promoter directly and increases its activity. These findings demonstrate the importance of glutaminolysis in the generation of Th17 and the direct control of Gls1 activity by the IL-17-promoting transcription factor ICER. Pharmaceutical modulation of the glutaminolysis pathway should be considered to control Th17-mediated pathology. PMID- 29463742 TI - Origins and genetic legacies of the Caribbean Taino. AB - The Caribbean was one of the last parts of the Americas to be settled by humans, but how and when the islands were first occupied remains a matter of debate. Ancient DNA can help answering these questions, but the work has been hampered by poor DNA preservation. We report the genome sequence of a 1,000-year-old Lucayan Taino individual recovered from the site of Preacher's Cave in the Bahamas. We sequenced her genome to 12.4-fold coverage and show that she is genetically most closely related to present-day Arawakan speakers from northern South America, suggesting that the ancestors of the Lucayans originated there. Further, we find no evidence for recent inbreeding or isolation in the ancient genome, suggesting that the Lucayans had a relatively large effective population size. Finally, we show that the native American components in some present-day Caribbean genomes are closely related to the ancient Taino, demonstrating an element of continuity between precontact populations and present-day Latino populations in the Caribbean. PMID- 29463743 TI - In vivo repressed genes of Vibrio cholerae reveal inverse requirements of an H+/Cl- transporter along the gastrointestinal passage. AB - The facultative human pathogen Vibrio cholerae changes its transcriptional profile upon oral ingestion by the host to facilitate survival and colonization fitness. Here, we used a modified version of recombination-based in vivo expression technology to investigate gene silencing during the in vivo passage, which has been understudied. Using a murine model of cholera, we screened a V. cholerae transposon library composed of 10,000 randomly generated reporter fusions and identified 101 in vivo repressed (ivr) genes. Our data indicate that constitutive expression of ivr genes reduces colonization fitness, highlighting the necessity to down-regulate these genes in vivo. For example, the ivr gene clcA, encoding an H+/Cl- transporter, could be linked to the acid tolerance response against hydrochloric acid. In a chloride-dependent manner, ClcA facilitates survival under low pH (e.g., the stomach), but its presence becomes detrimental under alkaline conditions (e.g., lower gastrointestinal tract). This pH-dependent clcA expression is controlled by the LysR-type activator AphB, which acts in concert with AphA to initiate the virulence cascade in V. cholerae after oral ingestion. Thus, transcriptional networks dictating induction of virulence factors and the repression of ivr genes overlap to regulate in vivo colonization dynamics. Overall, the results presented herein highlight the impact of spatiotemporal gene silencing in vivo. The molecular characterization of the underlying mechanisms can provide important insights into in vivo physiology and virulence network regulation. PMID- 29463744 TI - MHC-mismatched mixed chimerism restores peripheral tolerance of noncross-reactive autoreactive T cells in NOD mice. AB - Autoimmune type 1 diabetes (T1D) and other autoimmune diseases are associated with particular MHC haplotypes and expansion of autoreactive T cells. Induction of MHC-mismatched but not -matched mixed chimerism by hematopoietic cell transplantation effectively reverses autoimmunity in diabetic nonobese diabetic (NOD) mice, even those with established diabetes. As expected, MHC-mismatched mixed chimerism mediates deletion in the thymus of host-type autoreactive T cells that have T-cell receptor (TCR) recognizing (cross-reacting with) donor-type antigen presenting cells (APCs), which have come to reside in the thymus. However, how MHC-mismatched mixed chimerism tolerizes host autoreactive T cells that recognize only self-MHC-peptide complexes remains unknown. Here, using NOD.Rag1-/-BDC2.5 or NOD.Rag1-/-BDC12-4.1 mice that have only noncross-reactive transgenic autoreactive T cells, we show that induction of MHC-mismatched but not -matched mixed chimerism restores immune tolerance of peripheral noncross reactive autoreactive T cells. MHC-mismatched mixed chimerism results in increased percentages of both donor- and host-type Foxp3+ Treg cells and up regulated expression of programmed death-ligand 1 (PD-L1) by host-type plasmacytoid dendritic cells (pDCs). Furthermore, adoptive transfer experiments showed that engraftment of donor-type dendritic cells (DCs) and expansion of donor-type Treg cells are required for tolerizing the noncross-reactive autoreactive T cells in the periphery, which are in association with up regulation of host-type DC expression of PD-L1 and increased percentage of host type Treg cells. Thus, induction of MHC-mismatched mixed chimerism may establish a peripheral tolerogenic DC and Treg network that actively tolerizes autoreactive T cells, even those with no TCR recognition of the donor APCs. PMID- 29463746 TI - Ants avoid superinfections by performing risk-adjusted sanitary care. AB - Being cared for when sick is a benefit of sociality that can reduce disease and improve survival of group members. However, individuals providing care risk contracting infectious diseases themselves. If they contract a low pathogen dose, they may develop low-level infections that do not cause disease but still affect host immunity by either decreasing or increasing the host's vulnerability to subsequent infections. Caring for contagious individuals can thus significantly alter the future disease susceptibility of caregivers. Using ants and their fungal pathogens as a model system, we tested if the altered disease susceptibility of experienced caregivers, in turn, affects their expression of sanitary care behavior. We found that low-level infections contracted during sanitary care had protective or neutral effects on secondary exposure to the same (homologous) pathogen but consistently caused high mortality on superinfection with a different (heterologous) pathogen. In response to this risk, the ants selectively adjusted the expression of their sanitary care. Specifically, the ants performed less grooming and more antimicrobial disinfection when caring for nestmates contaminated with heterologous pathogens compared with homologous ones. By modulating the components of sanitary care in this way the ants acquired less infectious particles of the heterologous pathogens, resulting in reduced superinfection. The performance of risk-adjusted sanitary care reveals the remarkable capacity of ants to react to changes in their disease susceptibility, according to their own infection history and to flexibly adjust collective care to individual risk. PMID- 29463745 TI - Rocaglates as dual-targeting agents for experimental cerebral malaria. AB - Cerebral malaria (CM) is a severe and rapidly progressing complication of infection by Plasmodium parasites that is associated with high rates of mortality and morbidity. Treatment options are currently few, and intervention with artemisinin (Art) has limited efficacy, a problem that is compounded by the emergence of resistance to Art in Plasmodium parasites. Rocaglates are a class of natural products derived from plants of the Aglaia genus that have been shown to interfere with eukaryotic initiation factor 4A (eIF4A), ultimately blocking initiation of protein synthesis. Here, we show that the rocaglate CR-1-31B perturbs association of Plasmodium falciparum eIF4A (PfeIF4A) with RNA. CR-1-31B shows potent prophylactic and therapeutic antiplasmodial activity in vivo in mouse models of infection with Plasmodium berghei (CM) and Plasmodium chabaudi (blood-stage malaria), and can also block replication of different clinical isolates of P. falciparum in human erythrocytes infected ex vivo, including drug resistant P. falciparum isolates. In vivo, a single dosing of CR-1-31B in P. berghei-infected animals is sufficient to provide protection against lethality. CR-1-31B is shown to dampen expression of the early proinflammatory response in myeloid cells in vitro and dampens the inflammatory response in vivo in P. berghei-infected mice. The dual activity of CR-1-31B as an antiplasmodial and as an inhibitor of the inflammatory response in myeloid cells should prove extremely valuable for therapeutic intervention in human cases of CM. PMID- 29463747 TI - Unexpected transformation of dissolved phenols to toxic dicarbonyls by hydroxyl radicals and UV light. AB - Water treatment systems frequently use strong oxidants or UV light to degrade chemicals that pose human health risks. Unfortunately, these treatments can result in the unintended transformation of organic contaminants into toxic products. We report an unexpected reaction through which exposure of phenolic compounds to hydroxyl radicals (*OH) or UV light results in the formation of toxic alpha,beta-unsaturated enedials and oxoenals. We show that these transformation products damage proteins by reacting with lysine and cysteine moieties. We demonstrate that phenolic compounds react with *OH produced by the increasingly popular UV/hydrogen peroxide (H2O2) water treatment process or UV light to form toxic enedials and oxoenals. In addition to raising concerns about potential health risks of oxidative water treatment, our findings suggest the potential for formation of these toxic compounds in sunlit surface waters, atmospheric water, and living cells. For the latter, our findings may be particularly relevant to efforts to understand cellular damage caused by in vivo production of reactive oxygen species. In particular, we demonstrate that exposure of the amino acid tyrosine to *OH yields an electrophilic enedial product that undergoes cross-linking reaction with both lysine and cysteine residues. PMID- 29463748 TI - Three-dimensional virtual histology enabled through cytoplasm-specific X-ray stain for microscopic and nanoscopic computed tomography. AB - Many histological methods require staining of the cytoplasm, which provides instrumental details for diagnosis. One major limitation is the production of 2D images obtained by destructive preparation of 3D tissue samples. X-ray absorption micro- and nanocomputed tomography (microCT and nanoCT) allows for a nondestructive investigation of a 3D tissue sample, and thus aids to determine regions of interest for further histological examinations. However, application of microCT and nanoCT to biological samples (e.g., biopsies) is limited by the missing contrast within soft tissue, which is important to visualize morphological details. We describe an eosin-based preparation overcoming the challenges of contrast enhancement and selectivity for certain tissues. The eosin based staining protocol is suitable for whole-organ staining, which then enables high-resolution microCT imaging of whole organs and nanoCT imaging of smaller tissue pieces retrieved from the original sample. Our results demonstrate suitability of the eosin-based staining method for diagnostic screening of 3D tissue samples without impeding further diagnostics through histological methods. PMID- 29463749 TI - Metabolic division of labor in microbial systems. AB - Metabolic pathways are often engineered in single microbial populations. However, the introduction of heterologous circuits into the host can create a substantial metabolic burden that limits the overall productivity of the system. This limitation could be overcome by metabolic division of labor (DOL), whereby distinct populations perform different steps in a metabolic pathway, reducing the burden each population will experience. While conceptually appealing, the conditions when DOL is advantageous have not been rigorously established. Here, we have analyzed 24 common architectures of metabolic pathways in which DOL can be implemented. Our analysis reveals general criteria defining the conditions that favor DOL, accounting for the burden or benefit of the pathway activity on the host populations as well as the transport and turnover of enzymes and intermediate metabolites. These criteria can help guide engineering of metabolic pathways and have implications for understanding evolution of natural microbial communities. PMID- 29463751 TI - Within- and across-trial dynamics of human EEG reveal cooperative interplay between reinforcement learning and working memory. AB - Learning from rewards and punishments is essential to survival and facilitates flexible human behavior. It is widely appreciated that multiple cognitive and reinforcement learning systems contribute to decision-making, but the nature of their interactions is elusive. Here, we leverage methods for extracting trial-by trial indices of reinforcement learning (RL) and working memory (WM) in human electro-encephalography to reveal single-trial computations beyond that afforded by behavior alone. Neural dynamics confirmed that increases in neural expectation were predictive of reduced neural surprise in the following feedback period, supporting central tenets of RL models. Within- and cross-trial dynamics revealed a cooperative interplay between systems for learning, in which WM contributes expectations to guide RL, despite competition between systems during choice. Together, these results provide a deeper understanding of how multiple neural systems interact for learning and decision-making and facilitate analysis of their disruption in clinical populations. PMID- 29463752 TI - Variational structure of Luttinger-Ward formalism and bold diagrammatic expansion for Euclidean lattice field theory. AB - The Luttinger-Ward functional was proposed more than five decades ago and has been used to formally justify most practically used Green's function methods for quantum many-body systems. Nonetheless, the very existence of the Luttinger-Ward functional has been challenged by recent theoretical and numerical evidence. We provide a rigorously justified Luttinger-Ward formalism, in the context of Euclidean lattice field theory. Using the Luttinger-Ward functional, the free energy can be variationally minimized with respect to Green's functions in its domain. We then derive the widely used bold diagrammatic expansion rigorously, without relying on formal arguments such as partial resummation of bare diagrams to infinite order. PMID- 29463750 TI - Light-activated protein interaction with high spatial subcellular confinement. AB - Methods to acutely manipulate protein interactions at the subcellular level are powerful tools in cell biology. Several blue-light-dependent optical dimerization tools have been developed. In these systems one protein component of the dimer (the bait) is directed to a specific subcellular location, while the other component (the prey) is fused to the protein of interest. Upon illumination, binding of the prey to the bait results in its subcellular redistribution. Here, we compared and quantified the extent of light-dependent dimer occurrence in small, subcellular volumes controlled by three such tools: Cry2/CIB1, iLID, and Magnets. We show that both the location of the photoreceptor protein(s) in the dimer pair and its (their) switch-off kinetics determine the subcellular volume where dimer formation occurs and the amount of protein recruited in the illuminated volume. Efficient spatial confinement of dimer to the area of illumination is achieved when the photosensitive component of the dimerization pair is tethered to the membrane of intracellular compartments and when on and off kinetics are extremely fast, as achieved with iLID or Magnets. Magnets and the iLID variants with the fastest switch-off kinetics induce and maintain protein dimerization in the smallest volume, although this comes at the expense of the total amount of dimer. These findings highlight the distinct features of different optical dimerization systems and will be useful guides in the choice of tools for specific applications. PMID- 29463753 TI - Signal peptide of HIV envelope protein impacts glycosylation and antigenicity of gp120. AB - The HIV-1 envelope protein (Env) of early-replicating viruses encodes several distinct transmission signatures. One such signature involves a reduced number of potential N-linked glycosylation sites (PNGs). This transmission signature underscores the importance of posttranslational modifications in the fitness of early-replicating isolates. An additional signature in Env involves the overrepresentation of basic amino acid residues at a specific position in the Env signal peptide (SP). In this report, we investigated the potential impact of this SP signature on gp120 glycosylation and antigenicity. Two recombinant gp120s were constructed, one derived from an isolate that lacks this signature and a second from an early-replicating isolate that includes this signature. Chimeric gp120s were also constructed in which the two SPs were swapped between the isolates. All four gp120s were probed with glycan-, structure- and receptor- specific probes in a surface plasmon resonance binding assay. We found that the SP of Env influences qualitative aspects of Env glycosylation that in turn affect the antigenicity of Env in a major way. The SP impacts the affinity of Env for DC-SIGN, a lectin receptor expressed on dendritic cells that is believed to play a role in mucosal transmission. Additionally, affinity for the monoclonal antibodies 17b and A32, which recognize a CD4-induced, open conformation of Env is also altered. These results demonstrate that natural variation in the SP of HIV Env can significantly impact the antigenicity of mature gp120. Thus, the SP is likely subject to antibody-mediated immune pressure. PMID- 29463755 TI - Crop intensification, land use, and on-farm energy-use efficiency during the worldwide spread of the green revolution. AB - We analyzed crop production, physical inputs, and land use at the country level to assess technological changes behind the threefold increase in global crop production from 1961 to 2014. We translated machinery, fuel, and fertilizer to embedded energy units that, when summed up, provided a measure of agricultural intensification (human subsidy per hectare) for crops in the 58 countries responsible for 95% of global production. Worldwide, there was a 137% increase in input use per hectare, reaching 13 EJ, or 2.6% of the world's primary energy supply, versus only a 10% increase in land use. Intensification was marked in Asia and Latin America, where input-use levels reached those that North America and Europe had in the earlier years of the period; the increase was more accentuated, irrespective of continent, for the 12 countries with mostly irrigated production. Half of the countries (28/58), mainly developed ones, had an average subsidy >5 GJ/ha/y (with fertilizers accounting for 27% in 1961 and 45% in 2014), with most of them (23/28) using about the same area or less than in 1961 (net land sparing of 31 Mha). Most of the remaining countries (24/30 with inputs <5 GJ/ha/y), mainly developing ones, increased their cropped area (net land extensification of 135 Mha). Overall, energy-use efficiency (crop output/inputs) followed a U-shaped trajectory starting at about 3 and finishing close to 4. The prospects of a more sustainable intensification are discussed, and the inadequacy of the land-sparing model expectation of protecting wilderness via intensified agriculture is highlighted. PMID- 29463754 TI - Translational control in the tumor microenvironment promotes lung metastasis: Phosphorylation of eIF4E in neutrophils. AB - The translation of mRNAs into proteins serves as a critical regulatory event in gene expression. In the context of cancer, deregulated translation is a hallmark of transformation, promoting the proliferation, survival, and metastatic capabilities of cancer cells. The best-studied factor involved in the translational control of cancer is the eukaryotic translation initiation factor 4E (eIF4E). We and others have shown that eIF4E availability and phosphorylation promote metastasis in mouse models of breast cancer by selectively augmenting the translation of mRNAs involved in invasion and metastasis. However, the impact of translational control in cell types within the tumor microenvironment (TME) is unknown. Here, we demonstrate that regulatory events affecting translation in cells of the TME impact cancer progression. Mice bearing a mutation in the phosphorylation site of eIF4E (S209A) in cells comprising the TME are resistant to the formation of lung metastases in a syngeneic mammary tumor model. This is associated with reduced survival of prometastatic neutrophils due to decreased expression of the antiapoptotic proteins BCL2 and MCL1. Furthermore, we demonstrate that pharmacological inhibition of eIF4E phosphorylation prevents metastatic progression in vivo, supporting the development of phosphorylation inhibitors for clinical use. PMID- 29463756 TI - Diagnostic utility of telomere length testing in a hospital-based setting. AB - Telomere length (TL) predicts the onset of cellular senescence in vitro but the diagnostic utility of TL measurement in clinical settings is not fully known. We tested the value of TL measurement by flow cytometry and FISH (flowFISH) in patients with mutations in telomerase and telomere maintenance genes. TL had a discrete and reproducible normal range with definable upper and lower boundaries. While TL above the 50th age-adjusted percentile had a 100% negative predictive value for clinically relevant mutations, the lower threshold in mutation carriers was age-dependent, and adult mutation carriers often overlapped with the lowest decile of controls. The extent of telomere shortening correlated with the age at diagnosis as well as the short telomere syndrome phenotype. Extremely short TL caused bone marrow failure and immunodeficiency in children and young adults, while milder defects manifested as pulmonary fibrosis-emphysema in adults. We prospectively examined whether TL altered treatment decisions for newly diagnosed idiopathic bone marrow failure patients and found abnormally short TL enriched for patients with mutations in some inherited bone marrow failure genes, such as RUNX1, in addition to telomerase and telomere maintenance genes. The result was actionable, altering the choice of treatment regimen and/or hematopoietic stem cell donor in one-fourth of the cases (9 of 38, 24%). We conclude that TL measurement by flowFISH, when used for targeted clinical indications and in limited settings, can influence treatment decisions in ways that improve outcome.

AB - Dengue hemorrhagic fever (DHF), a severe manifestation of dengue viral infection that can cause severe bleeding, organ impairment, and even death, affects between 15,000 and 105,000 people each year in Thailand. While all Thai provinces experience at least one DHF case most years, the distribution of cases shifts regionally from year to year. Accurately forecasting where DHF outbreaks occur before the dengue season could help public health officials prioritize public health activities. We develop statistical models that use biologically plausible covariates, observed by April each year, to forecast the cumulative DHF incidence for the remainder of the year. We perform cross-validation during the training phase (2000-2009) to select the covariates for these models. A parsimonious model based on preseason incidence outperforms the 10-y median for 65% of province level annual forecasts, reduces the mean absolute error by 19%, and successfully forecasts outbreaks (area under the receiver operating characteristic curve = 0.84) over the testing period (2010-2014). We find that functions of past incidence contribute most strongly to model performance, whereas the importance of environmental covariates varies regionally. This work illustrates that accurate forecasts of dengue risk are possible in a policy-relevant timeframe. PMID- 29463759 TI - Axogenic mechanism enhances retinal ganglion cell excitability during early progression in glaucoma. AB - Diseases of the brain involve early axon dysfunction that often precedes outright degeneration. Pruning of dendrites and their synapses represents a potential driver of axonopathy by reducing activity. Optic nerve degeneration in glaucoma, the world's leading cause of irreversible blindness, involves early stress to retinal ganglion cell (RGC) axons from sensitivity to intraocular pressure (IOP). This sensitivity also influences survival of RGC dendrites and excitatory synapses in the retina. Here we tested in individual RGCs identified by type the relationship between dendritic organization and axon signaling to light following modest, short-term elevations in pressure. We found dendritic pruning occurred early, by 2 wk of elevation, and independent of whether the RGC responded to light onset (ON cells) or offset (OFF cells). Pruning was similarly independent of ON and OFF in the DBA/2J mouse, a chronic glaucoma model. Paradoxically, all RGCs, even those with significant pruning, demonstrated a transient increase in axon firing in response to the preferred light stimulus that occurred on a backdrop of generally enhanced excitability. The increased response was not through conventional presynaptic signaling, but rather depended on voltage sensitive sodium channels that increased transiently in the axon. Pruning, axon dysfunction, and deficits in visual acuity did not progress between 2 and 4 wk of elevation. These results suggest neurodegeneration in glaucoma involves an early axogenic response that counters IOP-related stress to excitatory dendritic architecture to slow progression and maintain signaling to the brain. Thus, short term exposure to elevated IOP may precondition the neural system to further insult. PMID- 29463760 TI - A comprehensive model for the proliferation-quiescence decision in response to endogenous DNA damage in human cells. AB - Human cells that suffer mild DNA damage can enter a reversible state of growth arrest known as quiescence. This decision to temporarily exit the cell cycle is essential to prevent the propagation of mutations, and most cancer cells harbor defects in the underlying control system. Here we present a mechanistic mathematical model to study the proliferation-quiescence decision in nontransformed human cells. We show that two bistable switches, the restriction point (RP) and the G1/S transition, mediate this decision by integrating DNA damage and mitogen signals. In particular, our data suggest that the cyclin dependent kinase inhibitor p21 (Cip1/Waf1), which is expressed in response to DNA damage, promotes quiescence by blocking positive feedback loops that facilitate G1 progression downstream of serum stimulation. Intriguingly, cells exploit bistability in the RP to convert graded p21 and mitogen signals into an all-or nothing cell-cycle response. The same mechanism creates a window of opportunity where G1 cells that have passed the RP can revert to quiescence if exposed to DNA damage. We present experimental evidence that cells gradually lose this ability to revert to quiescence as they progress through G1 and that the onset of rapid p21 degradation at the G1/S transition prevents this response altogether, insulating S phase from mild, endogenous DNA damage. Thus, two bistable switches conspire in the early cell cycle to provide both sensitivity and robustness to external stimuli. PMID- 29463762 TI - From global scaling to the dynamics of individual cities. AB - Scaling has been proposed as a powerful tool to analyze the properties of complex systems and in particular for cities where it describes how various properties change with population. The empirical study of scaling on a wide range of urban datasets displays apparent nonlinear behaviors whose statistical validity and meaning were recently the focus of many debates. We discuss here another aspect, which is the implication of such scaling forms on individual cities and how they can be used for predicting the behavior of a city when its population changes. We illustrate this discussion in the case of delay due to traffic congestion with a dataset of 101 US cities in the years 1982-2014. We show that the scaling form obtained by agglomerating all of the available data for different cities and for different years does display a nonlinear behavior, but which appears to be unrelated to the dynamics of individual cities when their population grows. In other words, the congestion-induced delay in a given city does not depend on its population only, but also on its previous history. This strong path dependency prohibits the existence of a simple scaling form valid for all cities and shows that we cannot always agglomerate the data for many different systems. More generally, these results also challenge the use of transversal data for understanding longitudinal series for cities. PMID- 29463761 TI - Cooption of heat shock regulatory system for anhydrobiosis in the sleeping chironomid Polypedilum vanderplanki. AB - Polypedilum vanderplanki is a striking and unique example of an insect that can survive almost complete desiccation. Its genome and a set of dehydration rehydration transcriptomes, together with the genome of Polypedilum nubifer (a congeneric desiccation-sensitive midge), were recently released. Here, using published and newly generated datasets reflecting detailed transcriptome changes during anhydrobiosis, as well as a developmental series, we show that the TCTAGAA DNA motif, which closely resembles the binding motif of the Drosophila melanogaster heat shock transcription activator (Hsf), is significantly enriched in the promoter regions of desiccation-induced genes in P. vanderplanki, such as genes encoding late embryogenesis abundant (LEA) proteins, thioredoxins, or trehalose metabolism-related genes, but not in P. nubifer Unlike P. nubifer, P. vanderplanki has double TCTAGAA sites upstream of the Hsf gene itself, which is probably responsible for the stronger activation of Hsf in P. vanderplanki during desiccation compared with P. nubifer To confirm the role of Hsf in desiccation induced gene activation, we used the Pv11 cell line, derived from P. vanderplanki embryo. After preincubation with trehalose, Pv11 cells can enter anhydrobiosis and survive desiccation. We showed that Hsf knockdown suppresses trehalose induced activation of multiple predicted Hsf targets (including P. vanderplanki specific LEA protein genes) and reduces the desiccation survival rate of Pv11 cells fivefold. Thus, cooption of the heat shock regulatory system has been an important evolutionary mechanism for adaptation to desiccation in P. vanderplanki. PMID- 29463763 TI - Irreversible inactivation of ISG15 by a viral leader protease enables alternative infection detection strategies. AB - In response to viral infection, cells mount a potent inflammatory response that relies on ISG15 and ubiquitin posttranslational modifications. Many viruses use deubiquitinases and deISGylases that reverse these modifications and antagonize host signaling processes. We here reveal that the leader protease, Lbpro, from foot-and-mouth disease virus (FMDV) targets ISG15 and to a lesser extent, ubiquitin in an unprecedented manner. Unlike canonical deISGylases that hydrolyze the isopeptide linkage after the C-terminal GlyGly motif, Lbpro cleaves the peptide bond preceding the GlyGly motif. Consequently, the GlyGly dipeptide remains attached to the substrate Lys, and cleaved ISG15 is rendered incompetent for reconjugation. A crystal structure of Lbpro bound to an engineered ISG15 suicide probe revealed the molecular basis for ISG15 proteolysis. Importantly, anti-GlyGly antibodies, developed for ubiquitin proteomics, are able to detect Lbpro cleavage products during viral infection. This opens avenues for infection detection of FMDV based on an immutable, host-derived epitope. PMID- 29463765 TI - T-CARQ: a BASHH trainee collaborative for audit, research and quality improvement.

PMID- 29463764 TI - Functional and physical interaction between yeast Hsp90 and Hsp70. AB - Heat shock protein 90 (Hsp90) is a highly conserved ATP-dependent molecular chaperone that is essential in eukaryotes. It is required for the activation and stabilization of more than 200 client proteins, including many kinases and steroid hormone receptors involved in cell-signaling pathways. Hsp90 chaperone activity requires collaboration with a subset of the many Hsp90 cochaperones, including the Hsp70 chaperone. In higher eukaryotes, the collaboration between Hsp90 and Hsp70 is indirect and involves Hop, a cochaperone that interacts with both Hsp90 and Hsp70. Here we show that yeast Hsp90 (Hsp82) and yeast Hsp70 (Ssa1), directly interact in vitro in the absence of the yeast Hop homolog (Sti1), and identify a region in the middle domain of yeast Hsp90 that is required for the interaction. In vivo results using Hsp90 substitution mutants showed that several residues in this region were important or essential for growth at high temperature. Moreover, mutants in this region were defective in interaction with Hsp70 in cell lysates. In vitro, the purified Hsp82 mutant proteins were defective in direct physical interaction with Ssa1 and in protein remodeling in collaboration with Ssa1 and cochaperones. This region of Hsp90 is also important for interactions with several Hsp90 cochaperones and client proteins, suggesting that collaboration between Hsp70 and Hsp90 in protein remodeling may be modulated through competition between Hsp70 and Hsp90 cochaperones for the interaction surface. PMID- 29463768 TI - Ethical implications of excessive cluster sizes in cluster randomised trials. AB - The cluster randomised trial (CRT) is commonly used in healthcare research. It is the gold-standard study design for evaluating healthcare policy interventions. A key characteristic of this design is that as more participants are included, in a fixed number of clusters, the increase in achievable power will level off. CRTs with cluster sizes that exceed the point of levelling-off will have excessive numbers of participants, even if they do not achieve nominal levels of power. Excessively large cluster sizes may have ethical implications due to exposing trial participants unnecessarily to the burdens of both participating in the trial and the potential risks of harm associated with the intervention. We explore these issues through the use of two case studies. Where data are routinely collected, available at minimum cost and the intervention poses low risk, the ethical implications of excessively large cluster sizes are likely to be low (case study 1). However, to maximise the social benefit of the study, identification of excessive cluster sizes can allow for prespecified and fully powered secondary analyses. In the second case study, while there is no burden through trial participation (because the outcome data are routinely collected and non-identifiable), the intervention might be considered to pose some indirect risk to patients and risks to the healthcare workers. In this case study it is therefore important that the inclusion of excessively large cluster sizes is justifiable on other grounds (perhaps to show sustainability). In any randomised controlled trial, including evaluations of health policy interventions, it is important to minimise the burdens and risks to participants. Funders, researchers and research ethics committees should be aware of the ethical issues of excessively large cluster sizes in cluster trials. PMID- 29463769 TI - Pilot randomised controlled trial to improve hand hygiene through mindful moments. AB - BACKGROUND: To evaluate the effectiveness of a brief mindfulness intervention on hand hygiene performance and mindful attention for inpatient physician teams. DESIGN: A pilot, pre-test/post-test randomised controlled mixed methods trial. SETTING: One academic medical centre in the USA. PARTICIPANTS: Four internal medicine physician teams consisting of one attending, one resident, two to three interns and up to four medical students. INTERVENTION: A facilitated, group-based educational discussion on how mindfulness, as practised through mindful hand hygiene, may improve clinical care and practices in the hospital setting. MAIN OUTCOMES AND MEASURES: The primary outcome was hand hygiene adherence (percentage) for each patient encounter. Other outcomes were observable mindful moments and mindful attention, measured using the Mindfulness Attention Awareness Scale, from baseline to post-intervention, and qualitative evaluation of the intervention. RESULTS: For attending physicians, hand hygiene adherence increased 14.1% in the intervention group compared with a decrease of 5.7% in the controls (P=0.035). For residents, the comparable figures were 24.7% (intervention) versus 0.2% (control) (P=0.064). For interns, adherence increased 10.0% with the intervention versus 4.2% in the controls (P=0.007). For medical students, adherence improved more in the control group (4.7% intervention vs 7.7% controls; P=0.003). An increase in mindfulness behaviours was observed for the intervention group (3.7%) versus controls (0.9%) (P=0.021). Self-reported mindful attention did not change (P=0.865). CONCLUSIONS: A brief, education-based mindfulness intervention improved hand hygiene in attending physicians and residents, but not in medical students. The intervention was well-received, increased mindfulness practice, and appears to be a feasible way to introduce mindfulness in the clinical setting. Future work instructing clinicians in mindfulness to improve hand hygiene may prove valuable. TRIAL REGISTRATION NUMBER: NCT 03165799; Results.

PMID- 29463771 TI - STRESS INDUCED FACTOR 2, a Leucine-Rich Repeat Kinase Regulates Basal Plant Pathogen Defense. AB - Protein kinases play fundamental roles in plant development and environmental stress responses. Here, we identified the STRESS INDUCED FACTOR (SIF) gene family, which encodes four leucine-rich repeat receptor-like protein kinases in Arabidopsis (Arabidopsis thaliana). The four genes, SIF1 to SIF4, are clustered in the genome and highly conserved, but they have temporally and spatially distinct expression patterns. We employed Arabidopsis SIF knockout mutants and overexpression transgenics to examine SIF involvement during plant pathogen defense. SIF genes are rapidly induced by biotic or abiotic stresses, and SIF proteins localize to the plasma membrane. Simultaneous knockout of SIF1 and SIF2 led to improved plant salt tolerance, whereas SIF2 overexpression enhanced PAMP triggered immunity and prompted basal plant defenses, significantly improving pathogen resistance. Furthermore, SIF2 overexpression plants exhibited up regulated expression of the defense-related genes WRKY53 and flg22-INDUCED RECEPTOR-LIKE KINASE1 as well as enhanced MPK3/MPK6 phosphorylation upon pathogen and elicitor treatments. The expression of the calcium signaling-related gene PHOSPHATE-INDUCED1 also was enhanced in the SIF2-overexpressing lines upon pathogen inoculation but repressed in the sif2 mutants. Bimolecular fluorescence complementation demonstrates that the BRI1-ASSOCIATED RECEPTOR KINASE1 protein is a coreceptor of the SIF2 kinase in the signal transduction pathway during pathogen invasion. These findings characterize a stress-responsive protein kinase family and illustrate how SIF2 modulates signal transduction for effective plant pathogenic defense. PMID- 29463772 TI - Proliferation of Regulatory DNA Elements Derived from Transposable Elements in the Maize Genome. AB - Genomic regions free of nucleosomes, which are hypersensitive to DNase I digestion, are known as DNase I hypersensitive sites (DHSs) and frequently contain cis-regulatory DNA elements. To investigate their prevalence and characteristics in maize (Zea mays), we developed high-resolution genome-wide DHS maps using a modified DNase-seq technique. Maize DHSs exhibit depletion of nucleosomes and low levels of DNA methylation and are enriched with conserved noncoding sequences (CNSs). We developed a protoplast-based transient transformation assay to assess the potential gene expression enhancer and/or promoter functions associated with DHSs, which showed that more than 80% of DHSs overlapping with CNSs showed an enhancer function. Strikingly, nearly 25% of maize DHSs were derived from transposable elements (TEs), including both class I and class II transposons. Interestingly, TE-derived DHSs (teDHSs) homologous to retrotransposons were enriched with sequences related to the intrinsic cis regulatory elements within the long terminal repeats of retrotransposons. We demonstrate that more than 80% of teDHSs can drive transcription of a reporter gene in protoplast assays. These results reveal the widespread occurrence of TE derived cis-regulatory sequences and suggest that teDHSs play a major role in transcriptional regulation in maize. PMID- 29463773 TI - The Citrus Transcription Factor CsMADS6 Modulates Carotenoid Metabolism by Directly Regulating Carotenogenic Genes. AB - Although remarkable progress has been made toward understanding carotenoid biosynthesis, the mechanisms that regulate the transcription of carotenogenic genes remain poorly understood. Lycopene beta-cyclases (LCYb) are critical enzymes located at the branch point of the carotenoid biosynthetic pathway. Here, we used the promoter sequence of LCYb1 as bait in a yeast one-hybrid screen for promoter-binding proteins from sweet orange (Citrus sinensis). This screen identified a MADS transcription factor, CsMADS6, that was coordinately expressed with fruit development and coloration. Acting as a nucleus-localized transcriptional activator, CsMADS6 directly bound the promoter of LCYb1 and activated its expression. Overexpression of CsMADS6 in citrus calli increased carotenoid contents and induced the expression of LCYb1 and other carotenogenic genes, including phytoene synthase (PSY), phytoene desaturase (PDS), and carotenoid cleavage dioxygenase1 (CCD1). CsMADS6 up-regulated the expression of PSY, PDS, and CCD1 by directly binding to their promoters, which suggested the multitargeted regulation of carotenoid metabolism by CsMADS6. In addition, the ectopic expression of CsMADS6 in tomato (Solanum lycopersicum) affected carotenoid contents and the expression of carotenogenic genes. The sepals of CsMADS6-overexpressing tomato lines exhibited dramatic changes in carotenoid profiles, accompanied by changes in plastid ultrastructure. Global transcriptome analysis of transgenic sepals revealed that CsMADS6 regulates a series of pathways that promote increases in flux through the carotenoid pathway. Overall, these findings establish that CsMADS6 directly regulates LCYb1 and other carotenogenic genes to coordinately and positively modulate carotenoid metabolism in plants, which may provide strategies to improve the nutritional quality of crops. PMID- 29463774 TI - The Ribosome-Bound Protein Pam68 Promotes Insertion of Chlorophyll into the CP47 Subunit of Photosystem II. AB - Photosystem II (PSII) is a large enzyme complex embedded in the thylakoid membrane of oxygenic phototrophs. The biogenesis of PSII requires the assembly of more than 30 subunits, with the assistance of a number of auxiliary proteins. In plants and cyanobacteria, the photosynthesis-affected mutant 68 (Pam68) is important for PSII assembly. However, its mechanisms of action remain unknown. Using a Synechocystis PCC 6803 strain expressing Flag-tagged Pam68, we purified a large protein complex containing ribosomes, SecY translocase, and the chlorophyll binding PSII inner antenna CP47. Using 2D gel electrophoresis, we identified a pigmented Pam68-CP47 subcomplex and found Pam68 bound to ribosomes. Our results show that Pam68 binds to ribosomes even in the absence of CP47 translation. Furthermore, Pam68 associates with CP47 at an early phase of its biogenesis and promotes the synthesis of this chlorophyll-binding polypeptide until the attachment of the small PSII subunit PsbH. Deletion of both Pam68 and PsbH nearly abolishes the synthesis of CP47, which can be restored by enhancing chlorophyll biosynthesis. These results strongly suggest that ribosome-bound Pam68 stabilizes membrane segments of CP47 and facilitates the insertion of chlorophyll molecules into the translated CP47 polypeptide chain. PMID- 29463776 TI - Abl and Arg mediate cysteine cathepsin secretion to facilitate melanoma invasion and metastasis. AB - The incidence of melanoma is increasing, particularly in young women, and the disease remains incurable for many because of its aggressive, metastatic nature and its high rate of resistance to conventional, targeted, and immunological agents. Cathepsins are proteases that are critical for melanoma progression and therapeutic resistance. Intracellular cathepsins cleave or degrade proteins that restrict cancer progression, whereas extracellular cathepsins directly cleave the extracellular matrix and activate proinvasive proteases in the tumor microenvironment. Cathepsin secretion is markedly increased in cancer cells. We investigated the signaling pathways leading to increased cathepsin secretion in melanoma cells. We found that the nonreceptor tyrosine kinases Abl and Arg (Abl/Arg) promoted the secretion of cathepsin B and cathepsin L by activating transcription factors (namely, Ets1, Sp1, and NF-kappaB/p65) that have key roles in the epithelial-mesenchymal transition (EMT), invasion, and therapeutic resistance. In some melanoma cell lines, Abl/Arg promoted the Ets1/p65-induced secretion of cathepsin B and cathepsin L in a kinase-independent manner, whereas in other melanoma lines, Abl/Arg promoted the kinase-dependent, Sp1/Ets1/p65 mediated induction of cathepsin L secretion and the Sp1/p65-mediated induction of cathepsin B secretion. As an indication of clinical relevance, the abundance of mRNAs encoding Abl/Arg, Sp1, Ets1, and cathepsins was positively correlated in primary melanomas, and Abl/Arg-driven invasion in culture and metastasis in vivo required cathepsin secretion. These data suggest that drugs targeting Abl kinases, many of which are FDA-approved, might inhibit cathepsin secretion in some melanomas and potentially other aggressive cancers harboring activated Abl kinases. PMID- 29463775 TI - The Transcriptional Coactivator ADA2b Recruits a Structural Maintenance Protein to Double-Strand Breaks during DNA Repair in Plants. AB - DNA damage occurs in all cells and can hinder chromosome stability and cell viability. Structural Maintenance of Chromosomes5/6 (SMC5/6) is a protein complex that functions as an evolutionarily conserved chromosomal ATPase critical for repairing DNA double-strand breaks (DSBs). However, the mechanisms regulating this complex in plants are poorly understood. Here, we identified the transcriptional coactivator ALTERATION/DEFICIENCY IN ACTIVATION2B (ADA2b) as an interactor of SMC5 in Arabidopsis (Arabidopsis thaliana). ADA2b is a conserved component of the Spt-Ada-Gcn5 acetyltransferase complex, which functions in transcriptional regulation. Characterization of mutant and knockdown Arabidopsis lines showed that disruption of either SMC5 or ADA2b resulted in enhanced DNA damage. Both SMC5 and ADA2b were associated with gamma-H2AX, a marker of DSBs, and the recruitment of SMC5 onto DSBs was dependent on ADA2b. In addition, overexpression of SMC5 in the ada2b mutant background stimulated cell death. Collectively, our results show that the interaction between ADA2b and SMC5 mediates DNA repair in plant cells, suggesting a functional association between these conserved proteins and further elucidating mechanisms of DNA damage repair in plants. PMID- 29463777 TI - The intracellular pyrimidine 5'-nucleotidase NT5C3A is a negative epigenetic factor in interferon and cytokine signaling. AB - The enzyme pyrimidine 5'-nucleotidase (NT5C3A), which mediates nucleotide catabolism, was previously thought to be restricted to blood cells. We showed that expression of the gene encoding NT5C3A was induced by type I interferons (IFNs) in multiple cell types and that NT5C3A suppressed cytokine production through inhibition of the nuclear factor kappaB (NF-kappaB) pathway. NT5C3A expression required both an intronic IFN-stimulated response element and the IFN stimulated transcription factor IRF1. Overexpression of NT5C3A, but not of its catalytic mutants, suppressed IL-8 production by HEK293 cells. Whereas knockdown of NT5C3A enhanced tumor necrosis factor (TNF)-stimulated IL-8 production, it reduced the IFN-mediated suppression of Il8 expression. Overexpression of NT5C3A increased the abundance of NAD+ and the activation of the sirtuins SIRT1 and SIRT6, which are NAD+-dependent deacetylases. NT5C3A-stimulated sirtuin activity resulted in deacetylation of histone H3 and the NF-kappaB subunit RelA (also known as p65), both of which were associated with the proximal region of the Il8 promoter, thus repressing the transcription of Il8 Together, these data identify an anti-inflammatory pathway that depends on the catalytic activity of NT5C3A and functions as a negative feedback regulator of inflammatory cytokine signaling. PMID- 29463779 TI - Coordinating the overall stomatal response of plants: Rapid leaf-to-leaf communication during light stress. AB - The plant canopy functions as an aerial array of light-harvesting antennas. To achieve maximal yield, each leaf within this array and the array as a whole need to rapidly adjust to naturally occurring fluctuations in light intensity and quality. Excessive light stress triggers the closing of pores in leaves called stomata to minimize moisture loss. We found that different leaves within the canopy of an Arabidopsis thaliana plant, including leaves not directly exposed to light, coordinated stomatal closure in response to light stress by sending and receiving rapid systemic signals. This response required the plant hormones abscisic acid and jasmonic acid and was mediated by a rapid autopropagating wave of reactive oxygen species (ROS) production. Furthermore, this response depended on the function of genes encoding the ROS-generating NADPH oxidase RBOHD and various stomatal regulators, such as the anion channel SLAC1, GHR1 (guard cell hydrogen peroxide resistant 1), and lipoxygenase 1 (LOX1). Our findings reveal that plants function as highly dynamic and coordinated organisms, optimizing the overall response of their canopies to fluctuating light intensities. PMID- 29463778 TI - A calcium-sensing receptor mutation causing hypocalcemia disrupts a transmembrane salt bridge to activate beta-arrestin-biased signaling. AB - The calcium-sensing receptor (CaSR) is a G protein-coupled receptor (GPCR) that signals through Gq/11 and Gi/o to stimulate cytosolic calcium (Ca2+i) and mitogen activated protein kinase (MAPK) signaling to control extracellular calcium homeostasis. Studies of loss- and gain-of-function CASR mutations, which cause familial hypocalciuric hypercalcemia type 1 (FHH1) and autosomal dominant hypocalcemia type 1 (ADH1), respectively, have revealed that the CaSR signals in a biased manner. Thus, some mutations associated with FHH1 lead to signaling predominantly through the MAPK pathway, whereas mutations associated with ADH1 preferentially enhance Ca2+i responses. We report a previously unidentified ADH1 associated R680G CaSR mutation, which led to the identification of a CaSR structural motif that mediates biased signaling. Expressing CaSRR680G in HEK 293 cells showed that this mutation increased MAPK signaling without altering Ca2+i responses. Moreover, this gain of function in MAPK activity occurred independently of Gq/11 and Gi/o and was mediated instead by a noncanonical pathway involving beta-arrestin proteins. Homology modeling and mutagenesis studies showed that the R680G CaSR mutation selectively enhanced beta-arrestin signaling by disrupting a salt bridge formed between Arg680 and Glu767, which are located in CaSR transmembrane domain 3 and extracellular loop 2, respectively. Thus, our results demonstrate CaSR signaling through beta-arrestin and the importance of the Arg680-Glu767 salt bridge in mediating signaling bias.

PMID- 29463782 TI - Endogenous volatile organic compounds in acute myeloid leukemia: origins and potential clinical applications. AB - Not unlike many cancer types, acute myeloid leukemia (AML) exhibits many metabolic changes and reprogramming, causing changes in lipid metabolism. Some of the distinct molecular abnormalities associated with AML also modify the metabolic changes. Both processes result in changes in the production of endogenous volatile organic compounds (VOCs). The increasing availability of highly sensitive methods for detecting trace chemicals provides the opportunity to investigate the role of patient-specific VOC finger-prints as biomarkers for detecting early relapse or minimal residual disease in AML. Since VOC production is reliant on metabolic activities, when combined with currently available methods, VOC analysis may identify within a group of patients with flow cytometric or molecular evidence of residual disease those most at risk for disease relapse. PMID- 29463783 TI - Comparison of Percutaneous Kyphoplasty and Bone Cement-Augmented Short-Segment Pedicle Screw Fixation for Management of Kummell Disease. AB - BACKGROUND The purpose of this study was to compare the efficacy of percutaneous kyphoplasty (PKP) and bone cement-augmented short segmental fixation (BCA+SSF) for treating Kummell disease. MATERIAL AND METHODS Between June 2013 and December 2015, 60 patients were treated with PKP or BCA+SSF. All patients were followed up for 12-36 months. We retrospectively reviewed outcomes, including Oswestry Disability Index (ODI), visual analogue scale (VAS), and kyphotic Cobb angle. RESULTS VAS, ODI, and Cobb angle, measured postoperatively and at the final follow-up, were lower than those measured preoperatively in both groups (P<0.05). VAS, ODI, and Cobb angle measured postoperatively demonstrated no significant differences when compared with those measured at the final follow-up in the PKP group (P>0.05). In the BCA+SSF group, VAS and ODI at the final follow-up were lower than those measured postoperatively (P<0.05), but no significant difference was found in the Cobb angle (P>0.05). The PKP group had better VAS and ODI than the BCA+SSF group, postoperatively (P<0.05). No significant difference was found in VAS and ODI at the final follow-up (P>0.05) or the Cobb angle measured postoperatively and at the final follow-up (P>0.05) between the 2 groups. Operative time, blood loss, and hospital stay in the PKP group were lower than those in the BCA+SSF group (P<0.05). No significant difference was found in complications (P>0.05). CONCLUSIONS PKP patients had better early clinical outcomes, shorter operation times and hospital admission times, and decreased blood loss, but had similar complications, radiographic results, and long-term clinical outcomes compared with BCA+SSF patients. PMID- 29463784 TI - Severe Fetal Distress and Placental Damage might be Associated with High Troponin I (cTnI) Levels in Mothers. AB - BACKGROUND Troponin I is the gold standard for the diagnosis of adult acute coronary syndrome. Although it is known that a hypoxic fetus may produce cTnI, fetal cTnI passage in maternal blood has never been documented. CASE REPORT We report a case where the rise of cTnI in the blood of a pregnant woman was not related to maternal heart disease. Instead, it might be suggestive of a fetal cardiac origin, as there was a severe placental insufficiency with a fetal intrauterine growth restriction. CONCLUSIONS This study suggests that the rise of cTnI in maternal blood in a cardiovascular healthy pregnant woman might have a fetal origin. After having excluded any maternal causes, cTnI elevation could be explained with the transfer of fetal cTnI through an injured placenta. PMID- 29463785 TI - Dysfunctional immunoregulation in human liver allograft rejection associated with compromised galectin-1/CD7 pathway function. AB - Regulatory T cells in rejected allograft patients display an inability to control responder T cells. Galectin-1 (Gal1) inhibits responder T cells through binding CD7. We investigated whether the dysfunctional immunoregulation in liver allograft rejection patients results from reduced regulatory T-cell Gal1 expression and/or responder T-cell CD7 expression. Circulating regulatory T cells and responder T cells were profiled from 31 acute rejection transplant patients, 85 transplant patients in remission, and 40 healthy controls. CD7+ and CD7- responder T cells were co-cultured with regulatory T cells to assess regulatory T cell suppressor function. Gal1-small interfering RNA was used to silence regulatory T-cell Gal1. The CD7+ cell percentage was inversely correlated with AST, ALT, and GGT levels. The proportions of CD7+ responder T cells and Gal1+ regulatory T cells were higher in healthy controls than in transplant patients in remission and lowest in acute rejection transplant patients. Notably, CD7+ responder T-cell susceptibility to Gal1+ regulatory T-cell control was ranked in the same manner. Silencing Gal1 expression in regulatory T cells reduced their ability to suppress CD7+ (but not CD7-) responder T cells. Additionally, the proportions of CD43+ and CD45+ responder T cells were higher in healthy controls than in acute rejection transplant patients. CD43 co-expression (but not CD45 co expression) on CD7+ responder T cells promoted their apoptosis in a Gal1 dependent manner. In sum, dysfunctional immunoregulation in liver allograft rejection patients can be partly attributed to reduced regulatory T-cell Gal1 expression and reduced responder T-cell CD7 expression. Responder T-cell CD43 downregulation in acute rejection patients may further contribute to reduced responder T-cell responsiveness to regulatory T-cell control. PMID- 29463786 TI - GRK5 functions as an oncogenic factor in non-small-cell lung cancer. AB - Lung cancer is the leading cause of cancer-related deaths worldwide, and non small-cell lung cancer (NSCLC) accounts for about 80% of all cases, which is the major subgroup of lung cancer. G protein-coupled receptor kinase 5 (GRK5) has been demonstrated to play pivotal roles in both development and progression of several pathological conditions including cancer. Here, we found that GRK5 expression was significantly increased in 539 NSCLC cancerous tissues than that in 99 normal non-cancerous tissues by immunohistochemistry analysis; we also showed intensive higher positive staining percentage in female and adenocarcinoma (ADC) NSCLC patients than that in male and squamous cell carcinoma (SCC) patients, respectively. In addition, GRK5 high expression NSCLC patients had a worse overall survival rate than the low expression patients. We provided evidence showing that both the mRNA and protein expression levels of GRK5 were increased in NSCLC cancerous cell lines (GLC-82, SPC-A-1, H520, H838, H358, A549, and H1299) comparing with that in normal human bronchial epithelium cell line (BEAS-2B), and identified many GRK5 mutations in NSCLC cancerous tissues. In addition, we found that depletion of GRK5 inhibited NSCLC cancerous cell proliferation, migration in vitro, and xenograft tumor formation in vivo. Furthermore, GRK5 knockdown promoted cell cycle arrest at G2/M phase and induced cellular apoptosis. In summary, our data reveal an oncogenic role of GRK5 in NSCLC progression, indicating that GRK5 could be used as a new therapeutic target in future. PMID- 29463787 TI - Committed sea-level rise under the Paris Agreement and the legacy of delayed mitigation action. AB - Sea-level rise is a major consequence of climate change that will continue long after emissions of greenhouse gases have stopped. The 2015 Paris Agreement aims at reducing climate-related risks by reducing greenhouse gas emissions to net zero and limiting global-mean temperature increase. Here we quantify the effect of these constraints on global sea-level rise until 2300, including Antarctic ice sheet instabilities. We estimate median sea-level rise between 0.7 and 1.2 m, if net-zero greenhouse gas emissions are sustained until 2300, varying with the pathway of emissions during this century. Temperature stabilization below 2 degrees C is insufficient to hold median sea-level rise until 2300 below 1.5 m. We find that each 5-year delay in near-term peaking of CO2 emissions increases median year 2300 sea-level rise estimates by ca. 0.2 m, and extreme sea-level rise estimates at the 95th percentile by up to 1 m. Our results underline the importance of near-term mitigation action for limiting long-term sea-level rise risks. PMID- 29463788 TI - Diverse genetic error modes constrain large-scale bio-based production. AB - A transition toward sustainable bio-based chemical production is important for green growth. However, productivity and yield frequently decrease as large-scale microbial fermentation progresses, commonly ascribed to phenotypic variation. Yet, given the high metabolic burden and toxicities, evolutionary processes may also constrain bio-based production. We experimentally simulate large-scale fermentation with mevalonic acid-producing Escherichia coli. By tracking growth rate and production, we uncover how populations fully sacrifice production to gain fitness within 70 generations. Using ultra-deep (>1000*) time-lapse sequencing of the pathway populations, we identify multiple recurring intra pathway genetic error modes. This genetic heterogeneity is only detected using deep-sequencing and new population-level bioinformatics, suggesting that the problem is underestimated. A quantitative model explains the population dynamics based on enrichment of spontaneous mutant cells. We validate our model by tuning production load and escape rate of the production host and apply multiple orthogonal strategies for postponing genetically driven production declines. PMID- 29463789 TI - Extraction condition optimization and effects of drying methods on physicochemical properties and antioxidant activities of polysaccharides from Astragalus cicer L. AB - Response surface methodology (RSM) including three variables was performed to optimize the extraction parameters of Astragalus cicer L. polysaccharides (ACPs). The influence of different drying techniques on the physicochemical properties and antioxidant abilities of ACPs were evaluated. The ACPs were dried with hot air (HD), vacuum (VD) and freeze drying (FD) methods. The optimal conditions for ACPs extraction were as follows: water to raw material ratio of 25 mL/g, extraction time of 61 min and temperature of 75 degrees C. Under these parameters, an ACPs yield of 10.97% was obtained. HPLC analysis showed that the monosaccharide compositions of the three ACPs dried with HD, VD or FD techniques were identical. The three ACPs exhibited antioxidant abilities in a concentration dependent manner. ACPs dried with the FD method (FD-ACPs) had the best antioxidant activities, which might be related to their smaller molecular weight and higher uronic acid content. At the determined concentration of 1 mg/mL, the ferric reducing power, and DPPH and ABTS free radical scavenging capacities of FD ACPs were 0.762, 75.30% and 99.21%, respectively. Therefore, FD was a good choice for the drying of Astragalus cicer L. polysaccharides. PMID- 29463790 TI - Contribution of TMEM16F to pyroptotic cell death. AB - Pyroptosis is a highly inflammatory form of programmed cell death that is caused by infection with intracellular pathogens and activation of canonical or noncanonical inflammasomes. The purinergic receptor P2X7 is activated by the noncanonical inflammasome and contributes essentially to pyroptotic cell death. The Ca2+ activated phospholipid scramblase and ion channel TMEM16F has been shown earlier to control cellular effects downstream of purinergic P2X7 receptors that ultimately lead to cell death. As pyroptotic cell death is accompanied by an increases in intracellular Ca2+, we asked whether TMEM16F is activated during pyroptosis. The N-terminal cleavage product of gasdermin D (GD-N) is an executioner of pyroptosis by forming large plasma membrane pores. Expression of GD-N enhanced basal Ca2+ levels and induced cell death. We observed that GD-N induced cell death in HEK293 and HAP1 cells, which was depending on expression of endogenous TMEM16F. GD-N activated large whole cell currents that were suppressed by knockdown or inhibition of TMEM16F. The results suggest that whole cell currents induced by the pore forming domain of gasdermin-D, are at least in part due to activation of TMEM16F. Knockdown of other TMEM16 paralogues expressed in HAP1 cells suggest TMEM16F as a crucial element during pyroptosis and excluded a role of other TMEM16 proteins. Thus TMEM16F supports pyroptosis and other forms of inflammatory cell death such as ferroptosis. Its potent inhibition by tannic acid may be part of the anti-inflammatory effects of flavonoids. PMID- 29463791 TI - The interactome and spatial redistribution feature of Ca2+ receptor protein calmodulin reveals a novel role in invadopodia-mediated invasion. AB - Numerous studies have shown that calmodulin (CaM) is a major regulator of calcium dependent signaling, which regulates cell proliferation, programmed cell death, and autophagy in cancer. However, limited information is available on mechanisms underlying the effect of CaM on the invasive property of glioblastoma multiforme (GBM) cells, especially with respect to invadopodia formation. In this study, we find that CaM serves as a prognostic factor for GBM, and it is strongly associated with the invasive nature of this tumor. Results of preliminary experiments indicated that CaM concentration was significantly correlated with the invasive capacity of and invadopodia formation by different GBM cell lines. CaM inhibition via a small hairpin RNA or a pharmacological inhibitor significantly disrupted invadopodia formation and MMP activity and downregulated vimentin expression. Moreover, CaM knockdown exerted a strong anti-invasive effect on GBM in vivo. Interestingly, epidermal growth factor treatment promoted CaM redistribution from the nucleus to the cytoplasm, eventually activating invadopodia-associated proteins by binding to them via their cytosolic-binding sites. Moreover, CaM inhibition suppressed the activation of invadopodia associated proteins. Thus, our findings provide a novel therapeutic strategy to impede GBM invasion by inhibiting invadopodia formation, and shed light on the spatial organization of CaM signals during GBM invasion. PMID- 29463792 TI - Glutamate-induced and NMDA receptor-mediated neurodegeneration entails P2Y1 receptor activation. AB - Despite the characteristic etiologies and phenotypes, different brain disorders rely on common pathogenic events. Glutamate-induced neurotoxicity is a pathogenic event shared by different brain disorders. Another event occurring in different brain pathological conditions is the increase of the extracellular ATP levels, which is now recognized as a danger and harmful signal in the brain, as heralded by the ability of P2 receptors (P2Rs) to affect a wide range of brain disorders. Yet, how ATP and P2R contribute to neurodegeneration remains poorly defined. For that purpose, we now examined the contribution of extracellular ATP and P2Rs to glutamate-induced neurodegeneration. We found both in vitro and in vivo that ATP/ADP through the activation of P2Y1R contributes to glutamate-induced neuronal death in the rat hippocampus. We found in cultured rat hippocampal neurons that the exposure to glutamate (100 uM) for 30 min triggers a sustained increase of extracellular ATP levels, which contributes to NMDA receptor (NMDAR)-mediated hippocampal neuronal death through the activation of P2Y1R. We also determined that P2Y1R is involved in excitotoxicity in vivo as the blockade of P2Y1R significantly attenuated rat hippocampal neuronal death upon the systemic administration of kainic acid or upon the intrahippocampal injection of quinolinic acid. This contribution of P2Y1R fades with increasing intensity of excitotoxic conditions, which indicates that P2Y1R is not contributing directly to neurodegeneration, rather behaving as a catalyst decreasing the threshold from which glutamate becomes neurotoxic. Moreover, we unraveled that such excitotoxicity process began with an early synaptotoxicity that was also prevented/attenuated by the antagonism of P2Y1R, both in vitro and in vivo. This should rely on the observed glutamate-induced calpain-mediated axonal cytoskeleton damage, most likely favored by a P2Y1R-driven increase of NMDAR mediated Ca2+ entry selectively in axons. This may constitute a degenerative mechanism shared by different brain diseases, particularly relevant at initial pathogenic stages.

AB - Alumina-to-alumina brazed joints were formed using 96.0 and 99.7 wt.% Al2O3 ceramics using 150 um thick Ticusil(r) (68.8Ag-26.7Cu-4.7 wt.% Ti) braze preforms. Brazing was conducted in a vacuum of 1 * 10-5 mbar at 850 degrees C for 10 minutes. Joint strengths were evaluated using four-point bend testing and were compared to the monolithic flexural strengths of standard alumina test bars according to ASTM C1161-13. Brazed joints made using 96.0 wt.% Al2O3 consistently outperformed brazed joints made using 99.7 wt.% Al2O3, despite similarities in both the flexural strengths of the standard alumina test bars and the microstructures of brazed joints. Secondary phase interaction led to the formation of Ti5Si3 reaction products at locations where the triple pocket grain boundaries of the 96.0 wt.% Al2O3 surface intersected the Ti-rich reaction layers. It is proposed that due to this interaction, brazed joints made using 96.0 wt.% Al2O3, which were relatively cost-effective to produce, achieved higher strengths than brazed joints made using 99.7 wt.% Al2O3. PMID- 29463793 TI - Aberrant Regulation of Notch3 Signaling Pathway in Polycystic Kidney Disease. AB - Polycystic kidney disease (PKD) is a genetic disorder characterized by fluid filled cysts in the kidney and liver that ultimately leads to end-stage renal disease. Currently there is no globally approved therapy for PKD. The Notch signaling pathway regulates cellular processes such as proliferation and de differentiation, which are cellular hallmarks of PKD. Thus we hypothesized that the Notch pathway plays a critical role in PKD. Evaluation of protein expression of Notch signaling components in kidneys of Autosomal Recessive PKD (ARPKD) and Autosomal Dominant PKD (ADPKD) mouse models and of ADPKD patients revealed that Notch pathway members, particularly Notch3, were consistently upregulated or activated in cyst-lining epithelial cells. Notch3 expression correlated with rapidly growing cysts and co-localized with the proliferation marker, PCNA. Importantly, Notch inhibition significantly decreased forskolin-induced Notch3 activation and proliferation of primary human ADPKD cells, and significantly reduced cyst formation and growth of human ADPKD cells cultured in collagen gels. Thus our data indicate that Notch3 is aberrantly activated and facilitates epithelial cell proliferation in PKD, and that inhibition of Notch signaling may prevent cyst formation and growth. PMID- 29463795 TI - The mark of vegetation change on Earth's surface energy balance. AB - Changing vegetation cover alters the radiative and non-radiative properties of the surface. The result of competing biophysical processes on Earth's surface energy balance varies spatially and seasonally, and can lead to warming or cooling depending on the specific vegetation change and background climate. Here we provide the first data-driven assessment of the potential effect on the full surface energy balance of multiple vegetation transitions at global scale. For this purpose we developed a novel methodology that is optimized to disentangle the effect of mixed vegetation cover on the surface climate. We show that perturbations in the surface energy balance generated by vegetation change from 2000 to 2015 have led to an average increase of 0.23 +/- 0.03 degrees C in local surface temperature where those vegetation changes occurred. Vegetation transitions behind this warming effect mainly relate to agricultural expansion in the tropics, where surface brightening and consequent reduction of net radiation does not counter-balance the increase in temperature associated with reduction in transpiration. This assessment will help the evaluation of land-based climate change mitigation plans. PMID- 29463796 TI - Winter Burst of Pristine Kashmir Valley Air. AB - The Kashmir Valley in India is one of the world's major tourist attractions and perceived as a pristine environment. Long term monitoring of fine particulate matter, PM2.5 (particles having aerodynamic diameter of 2.5 MUm or less), responsible for deteriorating human health, has been done for the period 2013-14. Results indicate that air quality of the capital city Srinagar (34.1 degrees N, 74.8 degrees E) deteriorates significantly in particular during winter, where level of PM2.5 touches a peak value of 348 MUg/m3 against the Indian permissible limit of 60 MUg/m3. The emissions due to domestic coal usage are found to be 1246.4 tons/yr, which accounts for 84% of the total annual emissions. The on-line high-resolution weather research and forecasting model with embedded chemistry module (WRF-Chem), which accounts for emission inventory developed in this region reproduced the seasonal variability reasonably well. Cold temperatures with dry conditions along with elevated level of biofuel emissions from domestic sector are found to be the major processes responsible for winter period particulate pollution. The back trajectories show that westerly winds originating from Afghanistan and surrounding areas also contribute to the high PM2.5 levels.

PMID- 29463797 TI - Induction of ER and mitochondrial stress by the alkylphosphocholine erufosine in oral squamous cell carcinoma cells. AB - Endoplasmic reticulum (ER) plays an essential role in cell function and survival. Accumulation of unfolded or misfolded proteins in the lumen of the ER activates the unfolded protein response (UPR), resulting in ER stress and subsequent apoptosis. The alkylphosphocholine erufosine is a known Akt-mTOR inhibitor in oral squamous cell carcinoma (OSCC). In the present study, we evaluate erufosine's role to induce ER and mitochondrial stress leading to autophagy, apoptosis, and ROS induction. The cellular toxicity of erufosine was determined in two OSCC cell lines and gene expression and enrichment analyses were performed. A positive enrichment of ER stress upon erufosine exposure was observed, which was verified at protein levels for the ER stress sensors and their downstream mediators. Knockdown and pharmacological inhibition of the ER stress sensors PERK and XBP1 revealed their involvement into erufosine's cellular effects, including proliferation, apoptosis, and autophagy induction. Autophagy was confirmed by increased acidic vacuoles and LC3-B levels. Upon erufosine exposure, calcium influx into the cytoplasm of the two OSCC cell lines was seen. Apoptosis was confirmed by nuclear staining, Annexin-V, and immunoblotting of caspases. The induction of mitochondrial stress upon erufosine exposure was predicted by gene set enrichment analysis (GSEA) and shown by erufosine's effect on mitochondrial membrane potential, ATP, and ROS production in OSCC cells. These data show that ER and mitochondrial targeting by erufosine represents a new facet of its mechanism of action as well as a promising new framework in the treatment of head and neck cancers. PMID- 29463799 TI - Remodeling of the Candida glabrata cell wall in the gastrointestinal tract affects the gut microbiota and the immune response. AB - The gastrointestinal (GI) microbiota acts a natural barrier to the proliferation of opportunistic pathogens. Candida glabrata is an opportunistic yeast pathogen that has adapted to colonize all segments of the human GI tract. We observed an increase in Escherichia coli, Enterococcus faecalis, and Bacteroides vulgatus populations, and a decrease in Lactobacillus johnsonii, Bacteroides thetaiotaomicron, and Bifidobacterium animalis in mice with DSS-induced colitis. This reduction was more pronounced for L. johnsonii during C. glabrata overgrowth. In addition, C. glabrata overgrowth increased mouse mortality and inflammatory parameters, and modulated the expression of intestinal receptors and signaling pathways. The C. glabrata cell wall underwent various changes during the course of C. glabrata colonization, and showed a significant increase in chitin. C. glabrata deficient in chitin synthase-3 induced fewer inflammatory parameters than the parental strain during intestinal inflammation. Oral administration of chitin attenuated the impact of colitis, and reduced the number of aerobic bacteria and C. glabrata overgrowth, while chitinase-3-like protein-1 increased. This study provides evidence that inflammation of the gut alters the microbial balance and leads to C. glabrata cell wall remodeling through an increase in chitin, which is involved in promoting persistence of C. glabrata in the gut. PMID- 29463800 TI - Mapping the dispersion of water wave channels. AB - Large classes of electronic, photonic, and acoustic crystals and quasi-crystals have been predicted to support topological wave-modes. Some of these modes are stabilized by certain symmetries but others occur as pure wave phenomena, hence they can be observed in many other media that support wave propagation. Surface water-waves are mechanical in nature but very different from the elastic waves, hence they can provide a new platform for studying topological wave-modes. Motivated by this perspective, we report theoretical and experimental characterizations of water-wave crystals obtained by periodic patterning of the water surface. In particular, we demonstrate the band structure of the spectra and existence of spectral gaps. PMID- 29463801 TI - Compensatory increases in tear volume and mucin levels associated with meibomian gland dysfunction caused by stearoyl-CoA desaturase-1 deficiency. AB - The stearoyl-CoA desaturase (SCD) family of enzymes catalyzes monounsaturated fatty acid synthesis by inserting a cis double bond at the Delta9 position of saturated fatty acids. Disruption of these enzymes has been reported to induce a severe dry skin phenotype. Since lipid abnormalities in the meibomian glands have been associated with dry eye, we analyzed selected eye tissues contributing to tear volume and composition in genetically SCD-1-deficient mice (SCD-1 KO), including the lacrimal glands and conjunctiva. Previous histopathological analysis had revealed atrophy and loss of meibomian glands; taken together with the increased goblet cell and MUC5AC expression in the conjunctiva reported here, these findings suggest that the tear volume and mucin levels secreted are enhanced in the absence of lipid secretion as a compensatory mechanism. The expression of lipid metabolism genes in lacrimal glands was decreased in SCD1 KO mice. Thus, these results provide new pathophysiological mechanisms to pursue with regard to meibomian gland dysfunction. In addition, lack of SCD-1 causes a compensatory increase in the tear volume and mucin levels associated with changes in expression of lipid metabolism genes. These results may be useful as a new concept for dry eye treatment strategies. PMID- 29463803 TI - ALCAM+ stromal cells: role in giant cell tumor of bone progression. AB - Giant cell tumor of bone(GCTB) is a special benign tumor with variable aggressiveness and recurrence rate. Increasing evidences suggest that a subset of cells called cancer stem cells (CSCs) are present as cancer-initiating cells in a range of malignant tumors. However, the role of CSCs in benign tumor such as GCTB remains unknown, and the connection between the presence of CSCs and biological characteristics of GCTB is unclear. To investigate this issue, we screened a panel of markers of normal stem cells and CSCs and found ALCAM+ stromal cells possessed characteristics of stem-like cells. Subsequently a series of experiments such cell proliferation, migration and invasion assays were performed to investigate the biological characteristics of ALCAM+ stromal cells in vivo and in vitro. The clinical significance of ALCAM expression were further evaluated using Kaplan-Meier analyses. The ALCAM+ GCTB cells showed the stem cell properties of self renewal and had the capacity to differentiate in vitro. The ALCAM+ GCTB cells showed increased resistance for chemotherapy- or radiation induced cell death. ALCAM knockdown reduced stem/progenitor characteristics in GCTB Cells. Furthermore, ALCAM expression was associated with outcome in GCTB patients. Our work demonstrates for the first time ALCAM+ tumorigenic sub population within stromal GCTB cells and may represent a potential therapeutic target in aggressive and recurrent GCTBs. PMID- 29463804 TI - The optimal movement patterns for mating encounters with sexually asymmetric detection ranges. AB - Animals have evolved various sex-specific characteristics to improve the efficiency of mating encounters. One is the sex-specific attracting signal. Signal receivers perform a combination of random search and navigation before and after signal detections. On the other hand, signal senders can also modify their movement patterns to optimize their encounter rates, which invokes a reverse side of random search problems that asks for the most efficient movement patterns of signal senders to be found by signal receivers. In this study, we focused on visual and auditory signals in particular, and quantified the efficiency of mating encounters of individual animals performing a Levy walk, a special class of random walk, with a variety of speeds before signal detection. We found that signal senders should move more slowly and/or less diffusively than receivers to improve mating encounters. The optimal movement patterns of senders ranged from relatively slow to stationary ones depending on the density of individuals, the effective range of signals, and the ability of receivers to locate senders. By focusing on the optimal movement patterns of individuals that are often assumed to be given targets, the present study provides insights into strategies of effective attraction beyond the case of mate search. PMID- 29463802 TI - Clonal dynamics towards the development of venetoclax resistance in chronic lymphocytic leukemia. AB - Deciphering the evolution of cancer cells under therapeutic pressure is a crucial step to understand the mechanisms that lead to treatment resistance. To this end, we analyzed whole-exome sequencing data of eight chronic lymphocytic leukemia (CLL) patients that developed resistance upon BCL2-inhibition by venetoclax. Here, we report recurrent mutations in BTG1 (2 patients) and homozygous deletions affecting CDKN2A/B (3 patients) that developed during treatment, as well as a mutation in BRAF and a high-level focal amplification of CD274 (PD-L1) that might pinpoint molecular aberrations offering structures for further therapeutic interventions. PMID- 29463805 TI - Ceramide-induced BOK promotes mitochondrial fission in preeclampsia. AB - Mitochondria are in a constant balance of fusing and dividing in response to cellular cues. Fusion creates healthy mitochondria, whereas fission results in removal of non-functional organelles. Changes in mitochondrial dynamics typify several human diseases. However, the contribution of mitochondrial dynamics to preeclampsia, a hypertensive disorder of pregnancy characterized by placental cell autophagy and death, remains unknown. Herein, we show that the mitochondrial dynamic balance in preeclamptic placentae is tilted toward fission (increased DRP1 expression/activation and decreased OPA1 expression). Increased phosphorylation of DRP1 (p-DRP1) in mitochondrial isolates from preeclamptic placentae and transmission electron microscopy corroborated augmented mitochondrial fragmentation in cytotrophoblast cells of PE placentae. Increased fission was accompanied by build-up of ceramides (CERs) in mitochondria from preeclamptic placentae relative to controls. Treatment of human choriocarcinoma JEG3 cells and primary isolated cytrophoblast cells with CER 16:0 enhanced mitochondrial fission. Loss- and gain-of-function experiments showed that Bcl-2 member BOK, whose expression is increased by CER, positively regulated p DRP1/DRP1 and MFN2 expression, and localized mitochondrial fission events to the ER/MAM compartments. We also identified that the BH3 and transmembrane domains of BOK were vital for BOK regulation of fission. Moreover, we found that full-length PTEN-induced putative kinase 1 (PINK1) and Parkin, were elevated in mitochondria from PE placentae, implicating mitophagy as the process that degrades excess mitochondria fragments produced from CER/BOK-induced fission in preeclampsia. In summary, our study uncovered a novel CER/BOK-induced regulation of mitochondrial fission and its functional consequence for heightened trophoblast cell autophagy in preeclampsia. PMID- 29463806 TI - Neural substrates of norm compliance in perceptual decisions. AB - Societal norms exert a powerful influence on our decisions. Behaviours motivated by norms, however, do not always concur with the responses mandated by decision relevant information potentially generating a conflict. To probe the interplay between normative and informational influences, we examined how prosocial norms impact on perceptual decisions subjects made in the context of a simultaneous presentation of social information. Participants displayed a bias in their perceptual decisions towards that mandated by social information. However, normative prescriptions modulated this bias bi-directionally depending on whether norms mandated a decision in accord or contrary to the contextual social information. At a neural level, the addition of a norms increased activity in prefrontal cortex and modulated functional connectivity between prefrontal and parietal areas. The bi-directional effect of our norms was captured by differential activations when participants decided against the social information. When norms indicated a decision in line with social information, non compliance modulated lateral prefrontal cortex activity. By contrast, when norms mandated a decision against social information norm compliance increased activity in the anterior cingulate cortex. Hence, social norms changed the balance between a reliance on perceptual and social information by modulating brain activity in regions associated with response inhibition and conflict monitoring. PMID- 29463807 TI - Passively mode-locked interband cascade optical frequency combs. AB - Since their inception, optical frequency combs have transformed a broad range of technical and scientific disciplines, spanning time keeping to navigation. Recently, dual comb spectroscopy has emerged as an attractive alternative to traditional Fourier transform spectroscopy, since it offers higher measurement sensitivity in a fraction of the time. Midwave infrared (mid-IR) frequency combs are especially promising as an effective means for probing the strong fundamental absorption lines of numerous chemical and biological agents. Mid-IR combs have been realized via frequency down-conversion of a near-IR comb, by optical pumping of a micro-resonator, and beyond 7 MUm by four-wave mixing in a quantum cascade laser. In this work, we demonstrate an electrically-driven frequency comb source that spans more than 1 THz of bandwidth centered near 3.6 MUm. This is achieved by passively mode-locking an interband cascade laser (ICL) with gain and saturable absorber sections monolithically integrated on the same chip. The new source will significantly enhance the capabilities of mid-IR multi-heterodyne frequency comb spectroscopy systems. PMID- 29463808 TI - A novel heterogeneous network-based method for drug response prediction in cancer cell lines. AB - An enduring challenge in personalized medicine lies in selecting a suitable drug for each individual patient. Here we concentrate on predicting drug responses based on a cohort of genomic, chemical structure, and target information. Therefore, a recently study such as GDSC has provided an unprecedented opportunity to infer the potential relationships between cell line and drug. While existing approach rely primarily on regression, classification or multiple kernel learning to predict drug responses. Synthetic approach indicates drug target and protein-protein interaction could have the potential to improve the prediction performance of drug response. In this study, we propose a novel heterogeneous network-based method, named as HNMDRP, to accurately predict cell line-drug associations through incorporating heterogeneity relationship among cell line, drug and target. Compared to previous study, HNMDRP can make good use of above heterogeneous information to predict drug responses. The validity of our method is verified not only by plotting the ROC curve, but also by predicting novel cell line-drug sensitive associations which have dependable literature evidences. This allows us possibly to suggest potential sensitive associations among cell lines and drugs. Matlab and R codes of HNMDRP can be found at following https://github.com/USTC-HIlab/HNMDRP . PMID- 29463809 TI - Delivery of exogenous mitochondria via centrifugation enhances cellular metabolic function. AB - Mitochondria are essential organelles involved in the maintenance of cell growth and function, and have been investigated as therapeutic targets in various diseases. Recent studies have demonstrated that direct mitochondrial transfer can restore cellular functions of cells with inherited or acquired mitochondrial dysfunction. However, previous mitochondrial transfer methods are inefficient and time-consuming. Here, we developed a simple and easy mitochondrial transfer protocol using centrifugation, which can be applied to any cell type. By our simple centrifugation method, we found that the isolated mitochondria could be successfully transferred into target cells, including mitochondrial DNA-deleted Rho0 cells and dexamethasone-treated atrophic muscle cells. We found that mitochondrial transfer normalised ATP production, mitochondrial membrane potential, mitochondrial reactive oxygen species level, and the oxygen consumption rate of the target cells. Furthermore, delivery of intact mitochondria blocked the AMPK/FoxO3/Atrogene pathway underlying muscle atrophy in atrophic muscle cells. Taken together, this simple and rapid mitochondrial transfer method can be used to treat mitochondrial dysfunction-related diseases. PMID- 29463810 TI - Dynamical complexity and computation in recurrent neural networks beyond their fixed point. AB - Spontaneous activity found in neural networks usually results in a reduction of computational performance. As a consequence, artificial neural networks are often operated at the edge of chaos, where the network is stable yet highly susceptible to input information. Surprisingly, regular spontaneous dynamics in Neural Networks beyond their resting state possess a high degree of spatio-temporal synchronization, a situation that can also be found in biological neural networks. Characterizing information preservation via complexity indices, we show how spatial synchronization allows rRNNs to reduce the negative impact of regular spontaneous dynamics on their computational performance. PMID- 29463811 TI - Consequences of VHL Loss on Global DNA Methylome. AB - In clear-cell renal cell carcinoma (ccRCC), loss of von Hippel-Lindau (VHL) tumour suppressor gene and reduced oxygen tension promote stabilisation of hypoxia-inducible factor (HIF) family of transcription factors, which promote changes in the expression of genes that contribute to oncogenesis. Multiple studies have demonstrated significant perturbations in DNA methylation in ccRCC via largely unclear mechanisms that modify the transcriptional output of tumour cells. Here, we show that the methylation status of the CpG dinucleotide within the consensus hypoxia-responsive element (HRE) markedly influences the binding of HIF and that the loss of VHL results in significant alterations in the DNA methylome. Surprisingly, hypoxia, which likewise promotes HIF stabilisation and activation, has relatively few effects on global DNA methylation. Gene expression analysis of ccRCC patient samples highlighted expression of a group of genes whose transcription correlated with methylation changes, including hypoxic responsive genes such as VEGF and TGF. These results suggest that the loss of VHL alters DNA methylation profile across the genome, commonly associated with and contributing to ccRCC progression. PMID- 29463812 TI - Metformin Use and Severe Dengue in Diabetic Adults. AB - Diabetes mellitus is a risk factor for severe dengue in adults, but few studies have examined the association between metformin use and disease severity in dengue. In addition to its effect on glucose control, metformin has been associated with pleiotropic properties in preclinical studies. Using a cohort of laboratory-confirmed adult (>=21 years) dengue patients with diabetes mellitus admitted to Tan Tock Seng Hospital, we conducted a retrospective cohort study involving 131 (58.7%) metformin users and 92 (41.3%) non-users. Dengue severity was categorized as dengue hemorrhagic fever (DHF) or dengue shock syndrome (DSS) in World Health Organization (WHO) 1997 criteria and severe dengue (SD) in WHO 2009 criteria. Multivariable Poisson regression with robust error variance was used to estimate risk ratio (RR). Compared with non-use, metformin use was associated with a decreased risk of developing severe dengue (adjusted risk ratio [aRR] = 0.60, 95% confidence interval [CI]: 0.37-0.98, P = 0.04). Additionally, there was an inverse dose-response relationship (aRR = 0.69, 95% CI: 0.49-0.98, P = 0.04) with dengue severity as classified by WHO 2009 criteria. Use of metformin, however, was not associated with dengue severity based on WHO 1997 criteria; and no dose-response relationship was noted. Our results suggest metformin use could attenuate disease severity in dengue-infected diabetes mellitus individuals. PMID- 29463813 TI - Oligomeric proanthocyanidins (OPCs) target cancer stem-like cells and suppress tumor organoid formation in colorectal cancer. AB - Proanthocyanidins are a heterogeneous group of flavan-3-ol or flavan-3,4-diol oligomers present in various fruits and vegetables. In particular, the smaller oligomeric subset of proanthocyanidins, termed the oligomeric proanthocyanidins (OPCs) appear to have potent anti-tumorigenic properties, but the underlying mechanisms for their effectiveness remain unclear. Herein, we utilized a series of in vitro, in vivo and patient-derived organoid approaches to systematically investigate the chemoprotective role of OPCs in colorectal cancer. OPCs exerted anti-tumorigenic effects through inhibition of cellular proliferation, and induced apoptosis and cell cycle arrest. Intriguingly, OPCs suppressed spheroid derived cancer stem-like cell formation and decreased the expression of intestinal cancer stem cell markers including LGR5, CD44 and CD133. Mechanistically, RNA-sequencing results confirmed that OPCs prominently interfered with developmental and self-renewal pathways and identified several self-renewal associated oncogenes targeted by OPCs. Furthermore, OPCs inhibited Hippo pathway through downregulation of its key transcriptional regulators, YAP and TAZ. Finally, we confirmed anti-tumorigenic effects of OPCs using multiple xenograft experiments and recapitulated its protective effects using patient derived colorectal tumor organoids. Collectively, we have comprehensively assessed anti-tumorigenic properties of OPCs and our data throws light on previously unrecognized chemopreventive mechanisms of OPCs highlighting its therapeutic potential. PMID- 29463815 TI - Photonic Generation of Triangular-shaped Waveform Based on External Modulation. AB - We present a novel approach for triangular-shaped waveform generation by applying optical single sideband (OSSB) modulation and optical carrier suppression (OCS) modulation to an input signal. Firstly, an OSSB modulated signal consists of an optical carrier and +1st-order sideband, is initially generated with a dual-drive Mach-Zehnder modulator (DD-MZM1) driven by a quadruple frequency RF signal. By tuning the amplitude of the RF signal and the bias of the DD-MZM1, the power ratio between the carrier and the +1st-order sideband is controlled as 19 dB. These two components are then transmitted to a DD-MZM2 which is driven by a fundamental frequency. After OCS modulation, four sidebands are existed in optical spectra of the modulated signal. By utilizing a fiber Bragg grating (FBG) to remove the undesired sideband, an output signal that features a triangular shaped waveform is finally achieved. PMID- 29463814 TI - LEM-3 is a midbody-tethered DNA nuclease that resolves chromatin bridges during late mitosis. AB - Faithful chromosome segregation and genome maintenance requires the removal of all DNA bridges that physically link chromosomes before cells divide. Using C. elegans embryos we show that the LEM-3/Ankle1 nuclease defines a previously undescribed genome integrity mechanism by processing DNA bridges right before cells divide. LEM-3 acts at the midbody, the structure where abscission occurs at the end of cytokinesis. LEM-3 localization depends on factors needed for midbody assembly, and LEM-3 accumulation is increased and prolonged when chromatin bridges are trapped at the cleavage plane. LEM-3 locally processes chromatin bridges that arise from incomplete DNA replication, unresolved recombination intermediates, or the perturbance of chromosome structure. Proper LEM-3 midbody localization and function is regulated by AIR-2/Aurora B kinase. Strikingly, LEM 3 acts cooperatively with the BRC-1/BRCA1 homologous recombination factor to promote genome integrity. These findings provide a molecular basis for the suspected role of the LEM-3 orthologue Ankle1 in human breast cancer. PMID- 29463816 TI - Social Observation Increases Functional Segregation between MPFC Subregions Predicting Prosocial Consumer Decisions. AB - Although it is now well documented that observation by others can be a powerful elicitor of prosocial behaviour, the underlying neural mechanism is yet to be explored. In the present fMRI study, we replicated the previously reported observer effect in ethical consumption, in that participants were more likely to purchase social products that are sold to support people in need than non-social products when being observed by others. fMRI data revealed that the anterior cingulate cortex (ACC) and the dorsomedial prefrontal cortex (dmPFC) encoded subject-specific value parameters of purchase decisions for social and non-social products, respectively, under social observation. The ACC showed strong functional coupling with the amygdala and the anterior insula when participants in the observation condition were making purchases of social versus non-social products. Finally, ventromedial prefrontal cortex (vmPFC) activity predicted faster reaction time and increased prosocial behavior during decisions to purchase social versus non-social products, regardless of social observation. The present findings suggest that subregions of the mPFC, namely the dmPFC, ACC, and vmPFC, are hierarchically organized to encode different levels of decision values from the value of context-sensitive reputation to that of internalized prosociality. PMID- 29463817 TI - Difficulties with tunneling of the cuffed catheter: a single-centre experience. AB - Tunneling of the cuffed catheter for hemodialysis is an important part of insertion procedure with faulty techniques being the cause of catheter dysfunctions. We retrospectively analyzed 737 double-lumen cuffed catheter procedures between 2008 and 2015 in patients aged 60 +/- 15years, requiring renal replacement therapy. Complications of tunneling included kinking, bleeding and other problems. In 20 of 737 (2.7%) procedures, the catheter kinked, which was observed in 7.7% of silicone and 0.6% of polyurethane catheters. Repositioning was attempted in 4, but was successful in only 2 cases. Catheter exchange was necessary in 16 cases, but the function was adequate in 2 cases, despite radiological signs of kinking. In 6 cases (1 patient with diabetes, 2 with chest anatomy changes and medical devices, 2 with systemic sclerosis and 1 with greatly enlarged superficial jugular veins) we faced particular difficulties requiring an individual solution by tunneling; these are described in detail. The cumulative catheter patency rate were 69%, 52% and 37% at 3, 6 and 12 months, respectively. In conclusion, the most frequent complication of tunneling was kinking, usually necessitating catheter exchange. The silicon catheter kinked more often than the polyurethane one. An individual approach is sometimes needed by patients with diabetes and anatomical changes of the chest. PMID- 29463818 TI - Changed frontal pole gene expression suggest altered interplay between neurotransmitter, developmental, and inflammatory pathways in schizophrenia. AB - Schizophrenia (Sz) probably occurs after genetically susceptible individuals encounter a deleterious environmental factor that triggers epigenetic mechanisms to change CNS gene expression. To determine if omnibus changes in CNS gene expression are present in Sz, we compared mRNA levels in the frontal pole (Brodmann's area (BA) 10), the dorsolateral prefrontal cortex (BA 9) and cingulate cortex (BA 33) from 15 subjects with Sz and 15 controls using the AffymetrixTM Human Exon 1.0 ST Array. Differences in mRNA levels (+/->=20%; p < 0.01) were identified (JMP Genomics 5.1) and used to predict pathways and gene x gene interactions that would be affected by the changes in gene expression using Ingenuity Pathway Analysis. There was significant variation in mRNA levels with diagnoses for 566 genes in BA 10, 65 genes in BA 9 and 40 genes in BA 33. In Sz, there was an over-representation of genes with changed expression involved in inflammation and development in BA 10, cell morphology in BA 9 and amino acid metabolism and small molecule biochemistry in BA 33. Using 94 genes with altered levels of expression in BA 10 from subjects with Sz, it was possible to construct an interactome of proven direct gene x gene interactions that was enriched for genes in inflammatory, developmental, oestrogen, serotonergic, cholinergic and NRG1 regulated pathways. Our data shows complex, regionally specific changes in cortical gene expression in Sz that are predicted to affect homeostasis between biochemical pathways already proposed to be important in the pathophysiology of the disorder.

AB - We report a novel method for fabrication of three-dimensional (3D) biocompatible micro-fluidic flow chambers in polydimethylsiloxane (PDMS) by 3D-printing water soluble polyvinyl alcohol (PVA) filaments as master scaffolds. The scaffolds are first embedded in the PDMS and later residue-free dissolved in water leaving an inscription of the scaffolds in the hardened PDMS. We demonstrate the strength of our method using a regular, cheap 3D printer, and evaluate the inscription process and the channels micro-fluidic properties using image analysis and digital holographic microscopy. Furthermore, we provide a protocol that allows for direct printing on coverslips and we show that flow chambers with a channel cross section down to 40 MUm * 300 MUm can be realized within 60 min. These flow channels are perfectly transparent, biocompatible and can be used for microscopic applications without further treatment. Our proposed protocols facilitate an easy, fast and adaptable production of micro-fluidic channel designs that are cost-effective, do not require specialized training and can be used for a variety of cell and bacterial assays. To help readers reproduce our micro-fluidic devices, we provide: full preparation protocols, 3D-printing CAD files for channel scaffolds and our custom-made molding device, 3D printer build-plate leveling instructions, and G-code.

AB - Pre-clinical monitoring of tumor growth and identification of distal metastasis requires a balance between accuracy and expediency. Bioluminescence imaging (BLI) is often used to track tumor growth but is primarily limited to planar 2 dimensional (2D) imaging. Consistent subject placement within a standard top mounted, single-detector small animal imager is vital to reducing variability in repeated same-animal measures over time. Here, we describe a method for tracking tumor development using a multi-angle BLI and photo-acoustic workflow. We correlate serial caliper measurements and 2D BLI to 360 degrees BLI and photo acoustic datasets for the same animals. Full 360 degrees BLI showed improved correlations with both volumes obtained from caliper measurements and photo acoustic segmentation, as compared to planar BLI. We also determined segmented tumor volumes from photo-acoustic datasets more accurately reflects true excised tumors' volumes compared to caliper measurements. Our results demonstrate the distinct advantages of both 360 degrees surface mapping by BLI and photo acoustic methodologies for non-invasive tracking of tumor growth in pre-clinical academic settings. Furthermore, our design is fully implementable in all top mounted, single-detector imagers, thereby providing the opportunity to shift the paradigm away from planar BLI into rapid BLI tomography applications. PMID- 29463822 TI - True gene-targeting events by CRISPR/Cas-induced DSB repair of the PPO locus with an ectopically integrated repair template. AB - In recent years, several tools have become available for improved gene-targeting (GT) in plants. DNA breaks at specific sites activate local DNA repair and recombination, including recombination with ectopic sequences leading to GT. Large-scale transformation with the repair template can be avoided by pre insertion of the repair template in the genome and liberation by sequence specific nucleases (in planta GT procedure). Here, we tested whether release of the repair template was required for GT. Plants were transformed with constructs encoding a CRISPR/Cas nuclease with a recognition site in the endogenous PPO gene and a repair template harboring a 5' truncated PPO gene with two amino acid substitutions rendering the enzyme insensitive to the herbicide butafenacil. Selection resulted in so-called true GT events, repaired via homologous recombination at both ends of the gene and transmitted to the next generation. As the template was surrounded by geminiviral LIR sequences, we also tested whether replication of the template could be induced by crossing-in an integrated geminivirus REP gene. However, we could not find evidence for repair template replication by REP and we obtained similar numbers of GT events in these plants. Thus, GT is possible without any further processing of the pre-inserted repair template. PMID- 29463821 TI - Amygdala hyper-connectivity in a mouse model of unpredictable early life stress. AB - Childhood maltreatment is associated with a wide range of psychopathologies including anxiety that emerge in childhood and in many cases persist in adulthood. Increased amygdala activation in response to threat and abnormal amygdala connectivity with frontolimbic brain regions, such as the hippocampus and the prefrontal cortex, are some of the most consistent findings seen in individuals exposed to childhood maltreatment. The underlying mechanisms responsible for these changes are difficult to study in humans but can be elucidated using animal models of early-life stress. Such studies are especially powerful in the mouse where precise control of the genetic background and the stress paradigm can be coupled with resting-state fMRI (rsfMRI) to map abnormal connectivity in circuits that regulate anxiety. To address this issue we first compared the effects of two models of early-life stress, limited bedding (LB) and unpredictable postnatal stress (UPS), on anxiety-like behavior in juvenile and adult mice. We found that UPS, but not LB, causes a robust increase in anxiety in juvenile and adult male mice. Next, we used rsfMRI to compare frontolimbic connectivity in control and UPS adult male mice. We found increased amygdala prefrontal cortex and amygdala-hippocampus connectivity in UPS. The strength of the amygdala-hippocampal and amygdala-prefrontal cortex connectivity was highly correlated with anxiety-like behavior in the open-field test and elevated plus maze. These findings are the first to link hyperconnectivity in frontolimbic circuits and increased anxiety in a mouse model of early-life stress, allowing for more mechanistic understanding of parallel findings in humans. PMID- 29463823 TI - Thermally Stable, High Performance Transfer Doping of Diamond using Transition Metal Oxides. AB - We report on optimisation of the environmental stability and high temperature operation of surface transfer doping in hydrogen-terminated diamond using MoO3 and V2O5 surface acceptor layers. In-situ annealing of the hydrogenated diamond surface at 400 degrees C was found to be crucial to enhance long-term doping stability. High temperature sheet resistance measurements up to 300 degrees C were performed to examine doping thermal stability. Exposure of MoO3 and V2O5 transfer-doped hydrogen-terminated diamond samples up to a temperature of 300 degrees C in ambient air showed significant and irreversible loss in surface conductivity. Thermal stability was found to improve dramatically however when similar thermal treatment was performed in vacuum or in ambient air when the oxide layers were encapsulated with a protective layer of hydrogen silsesquioxane (HSQ). Inspection of the films by X-ray diffraction revealed greater crystallisation of the MoO3 layers following thermal treatment in ambient air compared to the V2O5 films which appeared to remain amorphous. These results suggest that proper encapsulation and passivation of these oxide materials as surface acceptor layers on hydrogen-terminated diamond is essential to maximise their environmental and thermal stability. PMID- 29463824 TI - Molecular basis of differential nitrogen use efficiencies and nitrogen source preferences in contrasting Arabidopsis accessions. AB - Natural accessions of Arabidopsis thaliana differ in their growth and development, but also vary dramatically in their nitrogen use efficiencies (NUE). The molecular basis for these differences has not been addressed yet. Experiments with five contrasting accessions grown in hydroponics at different levels of inorganic nitrogen confirmed low NUE of Col-0 and higher NUE in Tsu-0. At constant external nitrogen supply, higher NUE was based on nitrogen capture, rather than utilization of nitrogen for shoot biomass. This changed when a limited nitrogen amount was supplied. Nevertheless, the total NUE sequence remained similar. Interestingly, the two most contrasting accessions, Col-0 and Tsu-0, differed in the capture of single inorganic nitrogen sources, reflected by the differential consumption of 15N label from ammonium or nitrate, when supplied together. Tsu-0 acquired more nitrate than Col-0, both in roots and shoots. This preference was directly correlated with the expression of certain nitrogen uptake and assimilation systems in the root. However, early transcriptional responses of the root to nitrate deprivation were similar in both accessions, suggesting that the sensing of the external lack of nitrate was not different in the more nitrogen use efficient accession. Thus, a robust rapid nitrate-deprivation signaling exists in both genotypes. PMID- 29463825 TI - Nanostructured Polymer Thin Films Fabricated with Brush-based Layer-by-Layer Self assembly for Site-selective Construction and Drug release. AB - Layer-by-Layer (LbL) self-assembly has been investigated for several decades. However, the conventional LbL method has performance problems on the chair-side caused by its cumbersome and time-consuming process. Thus, we investigate a new LbL self-assembly technique for the fast and high efficient preparation process based on the brush. The multilayer films fabricated by simple sequential brushing of polyelectrolyte solutions are compared to the classical dipping method. We characterize the multilayer films by characteristics such as their morphology and thickness, and compare them against those of the classic method by profilometry, atomic force microscopy. We prepare multilayer films with biocompatible polyelectrolytes, chitosan, and alginate incorporated with a hydrophobic drug carrier. For the drug carrier, a poly(ethylene glycol)-block-poly(epsilon caprolactone) (PEG-b-PCL) block copolymer is introduced to construct micelles containing dexamethasone, which is a well-known osteogenesis-inducing drug. The hydrogen bonding behavior between adjacent layers and micelles is investigated by Fourier transform infrared spectroscopy. Additionally, we analyze the release profiles, degradation profiles and toxicity of the multilayer films for biomedical applications. From these results, we can identify the brushing LbL method as a reliable and more efficient multilayer film-construction process compared to conventional dipping LbL, especially for practical applications in dental and clinical situations. PMID- 29463826 TI - VPS4 is a dynamic component of the centrosome that regulates centrosome localization of gamma-tubulin, centriolar satellite stability and ciliogenesis. AB - The hexameric AAA ATPase VPS4 facilitates ESCRT III filament disassembly on diverse intracellular membranes. ESCRT III components and VPS4 have been localized to the ciliary transition zone and spindle poles and reported to affect centrosome duplication and spindle pole stability. How the canonical ESCRT pathway could mediate these events is unclear. We studied the association of VPS4 with centrosomes and found that GFP-VPS4 was a dynamic component of both mother and daughter centrioles. A mutant, VPS4EQ, which can't hydrolyze ATP, was less dynamic and accumulated at centrosomes. Centrosome localization of the VPS4EQ mutant, caused reduced gamma-tubulin levels at centrosomes and consequently decreased microtubule growth and altered centrosome positioning. In addition, preventing VPS4 ATP hydrolysis nearly eliminated centriolar satellites and paused ciliogensis after formation of the ciliary vesicle. Zebrafish embryos injected with GFP-VPS4EQ mRNA were less viable, exhibited developmental defects and had fewer cilia in Kupffer's vesicle. Surprisingly, ESCRT III proteins seldom localized to centrosomes and their depletion did not lead to these phenotypes. Our data support an ESCRT III-independent function for VPS4 at the centrosome and reveal that this evolutionary conserved AAA ATPase influences diverse centrosome functions and, as a result, global cellular architecture and development.

AB - Long non-coding RNA (lncRNA) AC026166.2-001 was found to be down-regulated in laryngeal squamous cell carcinoma (LSCC) tissues and metastatic neck lymph nodes. Decreased AC026166.2-001 was associated with poorer prognosis and may act as a novel biomarker for LSCC patients. In this study, AC026166.2-001 was overexpressed by a lentivirus vector and down-regulated by a small interfering RNA (siRNA). The results of real-time cell analysis (RTCA) and a plate colony formation assay showed that AC026166.2-001 inhibited LSCC cell proliferation and the clone-forming capacity. Cell cycle distribution and related protein changes were measured by flow cytometry. AC026166.2-001 arrested the cell cycle at the G1 phase and induced apoptosis. In addition, AC026166.2-001 decreased cell migration as measured by wound healing assays and transwell migration assays. Moreover, luciferase reporter assay and Western blotting results suggested that AC026166.2 001 acts as a sponge of miR-24-3p and regulates the expression of p27 and cyclin D1. The in vivo results showed that AC026166.2-001 significantly suppressed the growth of LSCC xenografts and promoted apoptosis. We validated the molecular mechanisms underlying AC026166.2-001 in LSCC. This is the first report of AC026166.2-001 acting as a tumor suppressor in LSCC by regulating the miR-24 3p/p27 axis. PMID- 29463828 TI - Blood T1* correction increases accuracy of extracellular volume measurements using 3T cardiovascular magnetic resonance: Comparison of T1 and T1* maps. AB - The goals were to compare the differences between ECVL (extracellular volume derived from myocardial T1 and blood T1), ECVc (combination of myocardial T1 and blood T1*), and ECVnL (derived from myocardium T1* and blood T1*), and to explore the diagnostic accuracy of these factors for discriminating between controls and patients. The Modified Look-Locker Inversion Recovery sequence was performed in 42 subjects to generate both T1 and T1* maps. Native and post-contrast T1 values for myocardium and blood pool were obtained, and ECVL, ECVc, and ECVnL were then calculated. The global ECVc values were smaller than the ECVL values (0.006, 2.11%, p < 0.001) and larger than the ECVnL values (0.06, 21.6%, p < 0.001) in all participants. The ECVc led to a 4-6% increase in the AUC value and a 24-32% reduction in the sample size to differentiate between the controls and other patients when compared with the ECVL. Blood T1* correction can improve the precision of blood T1 values and can consequently increase the accuracy of the extracellular volume fraction measurement. The ECVc can be used to improve diagnostic accuracy and reduce the sample size required for a clinical study. PMID- 29463829 TI - Patternable and Widely Colour-Tunable Elastomer-Based Electroluminescent Devices. AB - We demonstrate wide colour tunability of polydimethylsiloxane-based alternating current-driven electroluminescent devices with intrinsically stretchable characteristics achieved by simply modulating the electrical frequency. By employing both a screen-printed emitting layer and frequency-dependent colour tuning of ZnS:Cu-based phosphors, we demonstrate various coloured patterned images in a single device. We also show enhanced colour-tuning performance by mixing multi-colour phosphors, which results in a broad range of available coordinates in colour space. We believe that our demonstrated method could be used for manipulating broader colour expression as well as in various applications involving stretchable devices. PMID- 29463830 TI - Evolving M-protein pattern in patients with smoldering multiple myeloma: impact on early progression. AB - Smoldering multiple myeloma (SMM) is a biologically heterogeneous, clinically defined entity with a variable rate of progression to symptomatic multiple myeloma (MM). Reliable markers for progression are critical for the development of potential therapeutic interventions. We retrospectively evaluated the predictive value of the evolving pattern of serum M-protein among other progression risk factors in 206 patients with SMM diagnosed between 1973 and 2012. Median time from recognition of evolving type to progression into symptomatic MM was 1.1 years (95% CI 0.5-2.0) and progression rate at 3 years was 71%. Development of the evolving type drastically worsened the prognostic estimation made at diagnosis for every covariate predictive of progression (serum M-protein size, bone marrow plasma cell infiltration, immunoparesis and Mayo Clinic risk). On average, the hazard ratio for progression to symptomatic MM increased to 5.1 (95% CI 3.4-7.6) after recognition of the evolving type. In conclusion, in patients with SMM the evolving pattern accurately predicts the risk of early progression to symptomatic disease, thereby allowing the identification of ultra-high risk patients who would be candidates for immediate therapy. PMID- 29463831 TI - Shikonin exerts antitumor activity in Burkitt's lymphoma by inhibiting C-MYC and PI3K/AKT/mTOR pathway and acts synergistically with doxorubicin. AB - Burkitt's lymphoma (BL) is a highly aggressive malignancy molecularly characterized by deregulation of the C-MYC proto-oncogene. Recently, it has been confirmed that phosphatidylinositol-3-kinase (PI3K) pathway activation is a crucial element in the malignant transformation of the B cells in BL. Despite the better outcome of adults with BL treated with high-intensity chemotherapy regimens, the overall survival rate for patients older than 60 years remains dismal. Shikonin, a natural naphthoquinone derived from Chinese herbal medicine plant, has the potential to induce cell death in a series of human cancer. In the present study, we investigated the effect and molecular mechanisms of Shikonin in treatment with BL. Shikonin suppressed cellular proliferation and induced caspase dependent apoptosis in BL cells. Inhibition of C-MYC and suppression of PI3K/AKT/mTOR pathway played critical roles in SHK-induced apoptosis in BL both in vitro and in vivo. Besides, Shikonin potentiated doxorubicin-induced growth inhibition and apoptosis in vitro. Furthermore, the growth of a subcutaneous xenograft tumor model of BL was significantly inhibited by shikonin. Importantly, we did not find the effect of shikonin on liver function in mice. In summary, these data suggest that shikonin may be an encouraging chemotherapeutic agent in the clinical treatment of BL. PMID- 29463832 TI - Frequency of early vascular aging and associated risk factors among an adult population in Latin America: the OPTIMO study. AB - The main objective was to estimate the frequency of early vascular aging (EVA) in a sample of subjects from Latin America, with emphasis in young adults. We included 1416 subjects from 12 countries in Latin America who provided information about lifestyle, cardiovascular risk factors (CVRF), and anthropometrics. We measured pulse wave velocity (PWV) as a marker of arterial stiffness, and blood pressure (BP) using an oscillometric device (Mobil-O-Graph). To determine the frequency of EVA, we used multiple linear regression to estimate each subject's PWV expected for his/her age and systolic BP, and compared with observed values to obtain standardized residuals (z-scores). We defined EVA when z-score was >=1.96. Finally, a multivariable logistic regression analysis was performed to determine baseline characteristics associated with EVA. Mean age was 49.9 +/- 15.5 years, male gender was 50.3%. Mean PWV was 7.52 m/s (SD 1.97), mean systolic BP was 125.3 mmHg (SD 16.7) and mean diastolic BP was 78.9 mmHg (SD 12.2). The frequency of EVA was 5.7% in the total population, 9.8% in adults of 40 years or less and 18.7% in those 30 years or less. In these young adults, multiple logistic regression analyses demonstrated that dyslipidemia and hypertension showed an independent association with EVA, and smoking a borderline association (p = 0.07). In conclusion, the frequency of EVA in a sample from Latin America was around 6%, with higher rates in young adults. These results would support the search of CVRF and EVA during early adulthood. PMID- 29463833 TI - Associations of NADPH oxidase-related genes with blood pressure changes and incident hypertension: The GenSalt Study. AB - Previous studies have indicated that reactive oxygen species produced by NADPH oxidase (Nox) are important risk factors of hypertension. The current study aims to examine the associations of Nox-related genes with longitudinal blood pressure (BP) changes and the risk of incident hypertension in the Genetic Epidemiology Network of Salt Sensitivity (GenSalt) follow-up study. A total of 1,768 participants from 633 families were included in our analysis. Nine BP measurements were obtained in the morning at baseline and during two follow-up visits. The mixed-effect models were used to investigate the associations of 52 tagged single-nucleotide polymorphisms in 11 Nox-related genes with BP changes and incident hypertension. Gene-based analyses were performed by truncated product method (TPM) and Versatile Gene-based Association Study (VEGAS). Over the 7.2 years of follow-up, systolic BP (SBP) and diastolic BP (DBP) increased, and 32.1% (512) of participants developed hypertension. SNPs rs12094228, rs16861188 and rs12066019 in NCF2 were significantly associated with longitudinal change in SBP (Pinteraction = 1.1 * 10-3, 2.8 * 10-3 and 1.2 * 10-3, respectively). Gene based analyses revealed that NCF2 was significantly associated with SBP (PTPM = 1.00 * 10-6, PVEGAS = 1.26 * 10-4) and DBP changes (PTPM = 5.84 * 10-4, PVEGAS = 1.04 * 10-3). These findings suggested that NCF2 may play an important role in BP changes over time in the Han Chinese population. PMID- 29463834 TI - Family history of colorectal cancer in first-degree relatives and metachronous colorectal adenoma. AB - OBJECTIVES: Little is known about the relationship between having a first-degree relative (FDR) with colorectal cancer (CRC) and risk for metachronous colorectal adenoma (CRA) following polypectomy. METHODS: We pooled data from seven prospective studies of 7697 patients with previously resected CRAs to quantify the relationship between having a FDR with CRC and risk for metachronous adenoma. RESULTS: Compared with having no family history of CRC, a positive family history in any FDR was significantly associated with increased odds of developing any metachronous CRA (OR = 1.14; 95% CI = 1.01-1.29). Higher odds of CRA were observed among individuals with an affected mother (OR = 1.27; 95% CI = 1.05 1.53) or sibling (OR = 1.34; 95% CI = 1.11-1.62) as compared with those without, whereas no association was shown for individuals with an affected father. Odds of having a metachronous CRA increased with number of affected FDRs, with ORs (95% CIs) of 1.07 (0.93-1.23) for one relative and 1.39 (1.02-1.91) for two or more. Younger age of diagnosis of a sibling was associated with higher odds of metachronous CRA, with ORs (95% CIs) of 1.66 (1.08-2.56) for diagnosis at <54 years; 1.34 (0.89-2.03) for 55-64 years; and 1.10 (0.70-1.72) for >65 years (p trend = 0.008). Although limited by sample size, results for advanced metachronous CRA were similar to those for any metachronous CRA. CONCLUSIONS: A family history of CRC is related to a modestly increased odds of metachronous CRA. Future research should explore whether having a FDR with CRC, particularly at a young age, should have a role in risk stratification for surveillance colonoscopy. PMID- 29463835 TI - Strontium isotope ratios of human hair record intra-city variations in tap water source. AB - The oxygen (18O/16O) isotope analysis of hair is commonly applied to reconstruct an individual's residence history. However, region-of-origin as determined from oxygen isotope values (delta18O) alone is often spatially indistinct. Adding additional geochemical recorders can refine region-of-origin estimates. In this capacity, strontium (87Sr/86Sr) isotope analysis has attracted increased interest. While 87Sr/86Sr reflects the influences of local geology, 87Sr/86Sr of hair includes both external environmental signals as well as the internal dietary indicators. To better understand the impact of these contributions to the spatial signal encoded within 87Sr/86Sr of hair, human hair was collected from three locations within Salt Lake City, Utah along with the donor's sex. The 87Sr/86Sr and delta18O of hair and local tap water were measured. There were no significant relationships between sex and either delta18O or 87Sr/86Sr of hair, nor between collection location and the delta18O of hair. However, we found significant associations between collection location and 87Sr/86Sr of hair. These findings suggest that interactions with local water may be an important source of Sr to human hair and that the 87Sr/86Sr of hair may have the capacity to record differences in 87Sr/86Sr of tap waters on small spatial scales. PMID- 29463836 TI - Demographic analysis of arrhenotokous parthenogenesis and bisexual reproduction of Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae). AB - Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) is a serious pest that is capable of bisexual and arrhenotokous reproduction. In arrhenotokous reproduction, virgin females initially produce male offspring; later, when their sons are sexually mature, the mothers begin bisexual reproduction by carrying out oedipal mating with their sons. Because a virgin female produces many male offspring before oedipal mating occurs, multiple oedipal mating is common. In this study, we investigated the effect of multiple oedipal mating on the population growth of F. occidentalis by using the age-stage, two-sex life table theory. In the arrhenotokous cohorts, all unfertilized eggs developed into males. In the bisexual cohorts, the offspring sex ratio was significantly female biased with the mean number of female offspring and male offspring being 72.68 and 29.00, respectively. These were the same as the net reproductive rate of female offspring and male offspring. In arrhenotokous cohorts, the number of males available for oedipal mating significantly affected the production of female offspring. The number of female offspring increased as the number of sons available for oedipal mating increased. Correctly characterizing this unique type of reproduction will provide important information for predicting the timing of future outbreaks of F. occidentalis, as well as aiding in formulating successful management strategies against the species. PMID- 29463837 TI - Giant circular dichroism of large-area extrinsic chiral metal nanocrecents. AB - In this work, we demonstrate the strong extrinsic chirality of the larger-area metal nanocrescents by experiments and simulations. Our results show that the metal nanocrescent exhibits giant and tunable circular dichroism (CD) effect, which is intensively dependent on the incident angle of light. We attribute the giant extrinsic chirality of the metal nanocrescent to the excitation efficiencies difference of localized surface plasmon resonance (LSPR) modes for two kinds of circularly polarized light at a non-zero incident angle. In experiment, the largest CD of 0.37 is obtained at the wavelength of 826 nm with the incident angle of 60 degrees . Furthermore, the CD spectra can be tuned flexibly by changing the metal nanocrescent diameter. Benefitting from the simple, low-cost and mature fabrication process, the proposed large-area metal nanocrescents are propitious to application. PMID- 29463839 TI - Heat transfer across a nanoscale pressurized air gap and its application in magnetic recording. AB - In this study, we investigated how a thermally actuated air bearing slider heats up a fast-spinning storage disk through a highly pressurized nanoscale air gap in a magnetic recording system. A Eulerian-description-based computational approach is developed considering heat conduction through a pressurized air film and near field radiation across the gap. A set of field equations that govern the air bearing dynamics, slider thermo-mechanics and disk heat dissipation are solved simultaneously through an iterative approach. A temperature field on the same order as the hot slider surface itself is found to be established in the disk. The effective local heat transfer coefficient is found to vary substantially with disk materials and linear speeds. This approach quantifies the magnitude of different thermal transport schemes and the accuracy is verified by an excellent agreement with our experiment, which measures the local slider temperature rise with a resistance temperature sensor. It also demonstrates an effective computational approach to treat transient thermal processes in a system of components with fast relative speed and different length scales. Finally, the investigated thermal transport mechanism leads to a substantial spacing change that has a significant impact on the spacing margin of today's magnetic storage systems. PMID- 29463838 TI - Interleukin-33 is activated by allergen- and necrosis-associated proteolytic activities to regulate its alarmin activity during epithelial damage. AB - Interleukin (IL)-33 is an IL-1 family alarmin released from damaged epithelial and endothelial barriers to elicit immune responses and allergic inflammation via its receptor ST2. Serine proteases released from neutrophils, mast cells and cytotoxic lymphocytes have been proposed to process the N-terminus of IL-33 to enhance its activity. Here we report that processing of full length IL-33 can occur in mice deficient in these immune cell protease activities. We sought alternative mechanisms for the proteolytic activation of IL-33 and discovered that exogenous allergen proteases and endogenous calpains, from damaged airway epithelial cells, can process full length IL-33 and increase its alarmin activity up to ~60-fold. Processed forms of IL-33 of apparent molecular weights ~18, 20, 22 and 23 kDa, were detected in human lungs consistent with some, but not all, proposed processing sites. Furthermore, allergen proteases degraded processed forms of IL-33 after cysteine residue oxidation. We suggest that IL-33 can sense the proteolytic and oxidative microenvironment during tissue injury that facilitate its rapid activation and inactivation to regulate the duration of its alarmin function. PMID- 29463840 TI - Cranial shape comparison for automated objective 3D craniosynostosis surgery planning. AB - Virtual planning of open cranial vault reconstruction is used to simulate and define an pre-operative plan for craniosynostosis surgery. However, virtual planning techniques are subjective and dependent on the experience and preferences of the surgical team. To develop an objective automated 3D pre operative planning technique for open cranial vault reconstructions, we used curvature maps for the shape comparison of the patient's skull with an age specific reference skull. We created an average skull for the age-group of 11-14 months. Also, we created an artificial test object and selected a cranial CT-scan of an 11 months old trigonocephaly patient as test case. Mesh data of skulls were created using marching cubes and raycasting. Curvature maps were computed using quadric surface fitting. The shape comparison was tested for the test object and the average skull. Finally, shape comparison was performed for the trigonocephalic skull with the average skull. Similar shapes and the area on the patient's skull that maximally corresponded in shape with the reference shape were correctly identified. This study showed that curvature maps allow the comparison of craniosynostosis skulls with age-appropriate average skulls and a first step towards an objective user-independent pre-operative planning technique for open cranial vault reconstructions is made. PMID- 29463841 TI - Chaotic Dynamics of Inner Ear Hair Cells. AB - Experimental records of active bundle motility are used to demonstrate the presence of a low-dimensional chaotic attractor in hair cell dynamics. Dimensionality tests from dynamic systems theory are applied to estimate the number of independent variables sufficient for modelling the hair cell response. Poincare maps are constructed to observe a quasiperiodic transition from chaos to order with increasing amplitudes of mechanical forcing. The onset of this transition is accompanied by a reduction of Kolmogorov entropy in the system and an increase in transfer entropy between the stimulus and the hair bundle, indicative of signal detection. A simple theoretical model is used to describe the observed chaotic dynamics. The model exhibits an enhancement of sensitivity to weak stimuli when the system is poised in the chaotic regime. We propose that chaos may play a role in the hair cell's ability to detect low-amplitude sounds. PMID- 29463842 TI - FOXQ1 controls the induced differentiation of melanocytic cells. AB - Oncogenic transcription factor FOXQ1 has been implicated in promotion of multiple transformed phenotypes in carcinoma cells. Recently, we have characterized FOXQ1 as a melanoma tumor suppressor that acts via repression of N-cadherin gene, and invasion and metastasis. Here we report that FOXQ1 induces differentiation in normal and transformed melanocytic cells at least partially via direct transcriptional activation of MITF gene, melanocytic lineage-specific regulator of differentiation. Importantly, we demonstrate that pigmentation induced in cultured melanocytic cells and in mice by activation of cAMP/CREB1 pathway depends in large part on FOXQ1. Moreover, our data reveal that FOXQ1 acts as a critical mediator of BRAFV600E-dependent regulation of MITF levels, thus providing a novel link between two major signal transduction pathways controlling MITF and differentiation in melanocytic cells. PMID- 29463843 TI - Prostaglandin D2 amplifies lupus disease through basophil accumulation in lymphoid organs. AB - In systemic lupus erythematosus (SLE), autoantibody production can lead to kidney damage and failure, known as lupus nephritis. Basophils amplify the synthesis of autoantibodies by accumulating in secondary lymphoid organs. Here, we show a role for prostaglandin D2 (PGD2) in the pathophysiology of SLE. Patients with SLE have increased expression of PGD2 receptors (PTGDR) on blood basophils and increased concentration of PGD2 metabolites in plasma. Through an autocrine mechanism dependent on both PTGDRs, PGD2 induces the externalization of CXCR4 on basophils, both in humans and mice, driving accumulation in secondary lymphoid organs. Although PGD2 can accelerate basophil-dependent disease, antagonizing PTGDRs in mice reduces lupus-like disease in spontaneous and induced mouse models. Our study identifies the PGD2/PTGDR axis as a ready-to-use therapeutic modality in SLE.

Although TRAF6 has been shown to have oncogenic activity in various malignant tumors, the details remain unclear. In this study, we demonstrated that TRAF6 facilitates Ras (G12V) and EGF-induced cellular transformation through EGFR. Silencing of TRAF6 expression significantly downregulated AP-1 activity, as well as MMP-2,9 expression after EGF stimulation. Furthermore, we found that TRAF6 plays an essential role in cutaneous squamous cell carcinoma (cSCC) malignant phenotypes, affecting cell growth and migration. CD147/Basigin, a transmembrane glycoprotein belonging to the immunoglobulin superfamily, is over-expressed in tumors and induces tumorigenesis. Our results showed that CD147 formed complex with EGFR and TRAF6. Knockdown of TRAF6 disrupted the CD147-EGFR complex, thereby inducing EGFR endocytosis. Therefore, TRAF6 might be a novel molecular target for cSCC prevention or therapy. PMID- 29463845 TI - Identification of stable reference genes for quantitative PCR in koalas. AB - To better understand host and immune response to diseases, gene expression studies require identification of reference genes with stable expression for accurate normalisation. This study describes the identification and testing of reference genes with stable expression profiles in koala lymph node tissues across two genetically distinct koala populations. From the 25 most stable genes identified in transcriptome analysis, 11 genes were selected for verification using reverse transcription quantitative PCR, in addition to the commonly used ACTB and GAPDH genes. The expression data were analysed using stable genes statistical software - geNorm, BestKeeper, NormFinder, the comparative DeltaCt method and RefFinder. All 13 genes showed relative stability in expression in koala lymph node tissues, however Tmem97 and Hmg20a were identified as the most stable genes across the two koala populations. PMID- 29463846 TI - Alteration of rocks by endolithic organisms is one of the pathways for the beginning of soils on Earth. AB - Subaerial endolithic systems of the current extreme environments on Earth provide exclusive insight into emergence and development of soils in the Precambrian when due to various stresses on the surfaces of hard rocks the cryptic niches inside them were much more plausible habitats for organisms than epilithic ones. Using an actualistic approach we demonstrate that transformation of silicate rocks by endolithic organisms is one of the possible pathways for the beginning of soils on Earth. This process led to the formation of soil-like bodies on rocks in situ and contributed to the raise of complexity in subaerial geosystems. Endolithic systems of East Antarctica lack the noise from vascular plants and are among the best available natural models to explore organo-mineral interactions of a very old "phylogenetic age" (cyanobacteria-to-mineral, fungi-to-mineral, lichen-to mineral). On the basis of our case study from East Antarctica we demonstrate that relatively simple endolithic systems of microbial and/or cryptogamic origin that exist and replicate on Earth over geological time scales employ the principles of organic matter stabilization strikingly similar to those known for modern full scale soils of various climates. PMID- 29463847 TI - Small-Vessel Vasculopathy Due to Aberrant Autophagy in LAMP-2 Deficiency. AB - Lysosomal associated membrane protein 2 (LAMP2) is physiologically implicated in autophagy. A genetic LAMP2 defect causes Danon disease, which consists of two major phenotypes of myopathy and cardiomyopathy. In addition, arteriopathy may manifest on rare occasions but the pathological basis remains unknown. We encountered two Danon families that developed small-vessel vasculopathy in the coronary or cerebral arteries. To investigate the underlying mechanisms, we characterized the biological features of LAMP-2-deficient mice and cultured cells. LAMP-2-deficient mice at 9-24 months of age showed medial thickening with luminal stenosis due to proliferation of vascular smooth muscle cells (VSMC) in muscular arteries. Ultrastructural analysis of VSMC revealed various autophagic vacuoles scattered throughout the cytoplasm, suggesting impaired autophagy of long-lived metabolites and degraded organelles (i.e., mitochondria). The VSMC in Lamp2 null mice expressed more vimentin but less alpha-smooth muscle actin (alpha SMA), indicating a switch from contractile to synthetic phenotype. Silencing of LAMP2 in cultured human brain VSMC showed the same phenotypic transition with mitochondrial fragmentation, enhanced mitochondrial respiration, and overproduction of reactive oxygen species (ROS). These findings indicate that LAMP-2 deficiency leads to arterial medial hypertrophy with the phenotypic conversion of VSMC, resulting from age-dependent accumulation of cellular waste generated by aberrant autophagy. PMID- 29463848 TI - Autoantibodies against the Immunoglobulin-Binding Region of Ro52 Link its Autoantigenicity with Pathogen Neutralization. AB - Ro52/TRIM21 plays a key role in antibody-dependent pathogen neutralization and is a major autoantigen in systemic lupus erythematosus, Sjogren's syndrome (SS), and other autoimmune diseases. Here we evaluated immunoreactivity against Ro52 related molecules in SS and healthy volunteers. Although most proteins examined were not antigenic, several TRIM paralogs, including TRIM22, and TRIM38, showed sporadic immunoreactivity in SS. In contrast, the murine Ro52 ortholog with limited linear homology demonstrated high levels of autoantibodies implicating the importance of shared conformational epitopes. To further explore the autoantigencity of Ro52, deletion and point mutant analyses were employed revealing previously hidden, robust autoantibodies directed against its C terminal immunoglobulin-binding domain. Another autoantibody, rheumatoid factor, targeting the Fc region of IgG, strongly overlapped with Ro52 seropositivity (odds ratio 14; P < 0.0001). These convergent mechanistic findings support a model whereby intracellular Ro52-bound antibody-coated pathogen complexes, released or misprocessed from infected cells, drive autoantigenicity against Ro52 and the Fc region of IgG. PMID- 29463849 TI - Reconstruction of kidney renal clear cell carcinoma evolution across pathological stages. AB - Although numerous studies on kidney renal clear cell carcinoma (KIRC) were carried out, the dynamic process of tumor formation was not clear yet. Inadequate attention was paid on the evolutionary paths among somatic mutations and their clinical implications. As the tumor initiation and evolution of KIRC were primarily associated with SNVs, we reconstructed an evolutionary process of KIRC using cross-sectional SNVs in different pathological stages. KIRC driver genes appeared early in the evolutionary tree, and the genes with moderate mutation frequency showed a pattern of stage-by-stage expansion. Although the individual gene mutations were not necessarily associated with survival outcome, the evolutionary paths such as VHL-PBRM1 and FMN2-PCLO could indicate stage-specific prognosis. Our results suggested that, besides mutation frequency, the evolutionary relationship among the mutated genes could facilitate to identify novel drivers and biomarkers for clinical utility. PMID- 29463850 TI - Microglia-mediated recovery from ALS-relevant motor neuron degeneration in a mouse model of TDP-43 proteinopathy. AB - Though motor neurons selectively degenerate in amyotrophic lateral sclerosis, other cell types are likely involved in this disease. We recently generated rNLS8 mice in which human TDP-43 (hTDP-43) pathology could be reversibly induced in neurons and expected that microglia would contribute to neurodegeneration. However, only subtle microglial changes were detected during disease in the spinal cord, despite progressive motor neuron loss; microglia still reacted to inflammatory triggers in these mice. Notably, after hTDP-43 expression was suppressed, microglia dramatically proliferated and changed their morphology and gene expression profiles. These abundant, reactive microglia selectively cleared neuronal hTDP-43. Finally, when microgliosis was blocked during the early recovery phase using PLX3397, a CSF1R and c-kit inhibitor, rNLS8 mice failed to regain full motor function, revealing an important neuroprotective role for microglia. Therefore, reactive microglia exert neuroprotective functions in this amyotrophic lateral sclerosis model, and definition of the underlying mechanism could point toward novel therapeutic strategies. PMID- 29463851 TI - DNA-based identification reveals illegal trade of threatened shark species in a global elasmobranch conservation hotspot. AB - Here, we report trading of endangered shark species in a world hotspot for elasmobranch conservation in Brazil. Data on shark fisheries are scarce in Brazil, although the northern and northeastern regions have the highest indices of shark bycatch. Harvest is made primarily with processed carcasses lacking head and fins, which hampers reliable species identification and law enforcement on illegal catches. We used partial sequences of two mitochondrial genes (COI and/or NADH2) to identify 17 shark species from 427 samples being harvested and marketed on the northern coast of Brazil. Nine species (53%) are listed under some extinction threat category according to Brazilian law and international authorities (IUCN - International Union for Conservation of Nature; CITES - Convention on International Trade of Endangered Species of Wild Fauna and Flora). The number increases to 13 (76%) if we also consider the Near Threatened category. Hammerhead sharks are under threat worldwide, and composed 18.7% of samples, with Sphyrna mokarran being the fourth most common species among samples. As illegal trade of threatened shark species is a worldwide conservation problem, molecular identification of processed meat or specimens lacking diagnostic body parts is a highly effective tool for species identification and law enforcement. PMID- 29463852 TI - Iodine insertion and dispersion of refractive index in organic single crystal semiconductor. AB - Insertion of halogens such as bromine or iodine affects the electronic polarizability of ions and the local field inside the medium, and thus modifies the refractive index. Acquiring precise knowledge of the dispersion of refractive index and ultimately tailoring conventional semiconductors for wide-range refractive index control have been a vital issue to resolve before realizing advanced organic optoelectronic devices. In this report, dispersions of the refractive index of a single crystal tetramethyltetraselenafulvalene [C10H12Se4] (TMTSF) are thoroughly studied from broadband interference modulations of photoluminescence (PL) spectra at various temperatures and doping levels. A large enhancement of the refractive index, more than 20% of the intrinsic value, is achieved with inclusion of a small composition of iodide ions, while the structural and optical properties remain mostly intact. Nearly temperature independent dispersion of the refractive index suggests that, unlike most polymers in which the thermal expansion coefficient dominates over the change of polarizability with temperature, the latter enhances significantly and may become more or less comparable to the thermal expansion coefficient given by 1.71 * 10 4/K, when single crystal TMTSF is doped by iodine. PMID- 29463853 TI - Spina bifida-predisposing heterozygous mutations in Planar Cell Polarity genes and Zic2 reduce bone mass in young mice. AB - Fractures are a common comorbidity in children with the neural tube defect (NTD) spina bifida. Mutations in the Wnt/planar cell polarity (PCP) pathway contribute to NTDs in humans and mice, but whether this pathway independently determines bone mass is poorly understood. Here, we first confirmed that core Wnt/PCP components are expressed in osteoblasts and osteoclasts in vitro. In vivo, we performed detailed uCT comparisons of bone structure in tibiae from young male mice heterozygous for NTD-associated mutations versus WT littermates. PCP signalling disruption caused by Vangl2 (Vangl2Lp/+) or Celsr1 (Celsr1Crsh/+) mutations significantly reduced trabecular bone mass and distal tibial cortical thickness. NTD-associated mutations in non-PCP transcription factors were also investigated. Pax3 mutation (Pax3Sp2H/+) had minimal effects on bone mass. Zic2 mutation (Zic2Ku/+) significantly altered the position of the tibia/fibula junction and diminished cortical bone in the proximal tibia. Beyond these genes, we bioinformatically documented the known extent of shared genetic networks between NTDs and bone properties. 46 genes involved in neural tube closure are annotated with bone-related ontologies. These findings document shared genetic networks between spina bifida risk and bone structure, including PCP components and Zic2. Genetic variants which predispose to spina bifida may therefore independently diminish bone mass. PMID- 29463854 TI - Autologous stem cell transplantation for primary mediastinal B-cell lymphoma: long-term outcome and role of post-transplant radiotherapy. A report of the European Society for Blood and Marrow Transplantation. AB - The purpose of this retrospective registry study was to investigate the outcome of autoSCT for primary mediastinal B-cell lymphoma (PMBCL) in the rituximab era, including the effects of eventual post-transplant radiotherapy (RT) consolidation. Patients with PMBCL aged between 18 and 70 years who were treated with a first autoSCT between 2000 and 2012 and registered with the EBMT were eligible. Eighty-six patients with confirmed PMBCL and the full data set required for this analysis were evaluable. Sixteen patients underwent autoSCT in remission after first-line therapy (CR/PR1), 44 patients were transplanted with chemosensitive relapsed or primary refractory disease (CR/PR >1), and 24 patients were chemorefractory at the time of autoSCT. With a median follow-up of 5 years, 3-year estimates of relapse incidence, progression-free survival, and overall survival were 6%, 94%, and 100% for CR/PR1; 31%, 64%, and 85% for CR/PR >1; and 52%, 39%, and 41% for REF, respectively. Whilst there was no significant benefit of post-transplant RT in the CR/PR >1 group, RT could completely prevent disease recurrence post d100 in the refractory group. In conclusion, autoSCT with or without consolidating RT is associated with excellent outcome in chemoimmunotherapy-sensitive PMBCL, whereas its benefits seem to be limited in chemoimmunotherapy-refractory disease. PMID- 29463855 TI - Zearalenone altered the cytoskeletal structure via ER stress- autophagy- oxidative stress pathway in mouse TM4 Sertoli cells. AB - The aim of this study was to investigate the molecular mechanisms of the destruction of cytoskeletal structure by Zearalenone (ZEA) in mouse-derived TM4 cells. In order to investigate the role of autophagy, oxidative stress and endoplasmic reticulum(ER) stress in the process of destruction of cytoskeletal structure, the effects of ZEA on the cell viability, cytoskeletal structure, autophagy, oxidative stress, ER stress, MAPK and PI3K- AKT- mTOR signaling pathways were studied. The data demonstrated that ZEA damaged the cytoskeletal structure through the induction of autophagy that leads to the alteration of cytoskeletal structure via elevated oxidative stress. Our results further showed that the autophagy was stimulated by ZEA through PI3K-AKT-mTOR and MAPK signaling pathways in TM4 cells. In addition, ZEA also induced the ER stress which was involved in the induction of the autophagy through inhibiting the ERK signal pathway to suppress the phosphorylation of mTOR. ER stress was involved in the damage of cytoskeletal structure through induction of autophagy by producing ROS. Taken together, this study revealed that ZEA altered the cytoskeletal structure via oxidative stress - autophagy- ER stress pathway in mouse TM4 Sertoli cells. PMID- 29463856 TI - Impact of Reduced Cerebellar EAAT Expression on Purkinje Cell Firing Pattern of NPC1-deficient Mice. AB - Niemann-Pick disease Type C1 (NPC1) is a rare hereditary neurodegenerative disease. NPC1-patients suffer, amongst others, from ataxia, based on a loss of cerebellar Purkinje cells (PCs). Impaired expression/function of excitatory amino acid transporters (EAATs) are suspected of contributing to PC-degeneration in hereditary spinocerebellar ataxias (SCAs). Thus, we studied EAAT-expression and its impact to PC-activity in NPC1-/-mice. Western blot revealed reduced EAAT1, EAAT2, EAAT4, and betaIII-spectrin levels in NPC1-/-mice. EAATs play a crucial role in synaptic transmission, thus we were interested in the impact of the reduced EAAT-expression on the function of PCs. Patch-clamp recordings of PCs showed no differences in the firing patterns of NPC1+/+and NPC1-/-mice using a low internal chloride concentration. Because EAAT4 also comprises a chloride permeable ion pore, we perturbed the chloride homeostasis using a high internal chloride concentration. We observed differences in the firing patterns of NPC1+/+and NPC1-/-mice, suggesting an impact of the altered EAAT4-expression. Additionally, the EAAT-antagonist DL-TBOA acts differently in NPC1+/+and NPC1-/ mice. Our data support the line of evidence that an altered EAAT expression/function is involved in neurodegeneration of PCs observed in SCAs. Thus, we suggest that similar pathogenic mechanisms contribute the loss of PCs in NPC1. PMID- 29463857 TI - Consequences of asynchronous heading in a perennial bunchgrass (Elymus excelsus). AB - Reproduction is vital to plant population adaptation. The consequences of asynchronous reproduction in a perennial bunchgrass grass is not well studied. The heading reproductive tillers from early to late forms a continuum due to asynchronous heading and flowering in Elymus excelsus population. In two peak years of production, the three-year-old and four-year-old reproductive tillers of experimental E. excelsus population were marked from the early to late heading stage every four days at five different heading times and these tillers were harvested at the dough stage, respectively. The growth, biomass, seed production and reproductive allocation were measured to analyze the consequences of asynchronous reproduction. Reproductive tiller height, biomass, inflorescence length, inflorescence biomass, floret number, seed number, seed biomass, seed-set percentage, biomass allocation to inflorescence (RA1) and to seed (RA2) significantly decreased with the delay of heading date over the two years. Above ten phenotypic characteristics exponentially increased at a significant or extremely significant level with increasing differences in reproductive period. Reproductive tillers preferentially allocated the biomass to inflorescences, and then the inflorescences preferentially allocated the biomass to seeds throughout reproductive period. Earlier heading tillers had more contribution to E. excelsus population adaptation and development in the two peak years of production. PMID- 29463858 TI - Clinical and genetic spectrum of AMPD2-related pontocerebellar hypoplasia type 9. AB - Pontocerebellar hypoplasia (PCH) represents a group of autosomal-recessive progressive neurodegenerative disorders of prenatal onset. Eleven PCH subtypes are classified according to clinical, neuroimaging and genetic findings. Individuals with PCH type 9 (PCH9) have a unique combination of postnatal microcephaly, hypoplastic cerebellum and pons, and hypoplastic or absent corpus callosum. PCH9 is caused by biallelic variants in AMPD2 encoding adenosine monophosphate deaminase 2; however, a homozygous AMPD2 frameshift variant has recently been reported in two family members with spastic paraplegia type 63 (SPG63). We identified homozygous or compound heterozygous AMPD2 variants in eight PCH-affected individuals from six families. The eight variants likely affect function and comprise one frameshift, one nonsense and six missense variants; seven of which were novel. The main clinical manifestations in the eight new patients and 17 previously reported individuals with biallelic AMPD2 variants were postnatal microcephaly, severe global developmental delay, spasticity, and central visual impairment. Brain imaging data identified hypomyelination, hypoplasia of the cerebellum and pons, atrophy of the cerebral cortex, complete or partial agenesis of the corpus callosum and the "figure 8" shape of the hypoplastic midbrain as consistent features. We broaden the AMPD2 related clinical spectrum by describing one individual without microcephaly and absence of the characteristic "figure 8" shape of the midbrain. The existence of various AMPD2 isoforms with different functions possibly explains the variability in phenotypes associated with AMPD2 variants: variants leaving some of the isoforms intact may cause SPG63, while those affecting all isoforms may result in the severe and early-onset PCH9. PMID- 29463859 TI - Biomining of MoS2 with Peptide-based Smart Biomaterials. AB - Biomining of valuable metals using a target specific approach promises increased purification yields and decreased cost. Target specificity can be implemented with proteins/peptides, the biological molecules, responsible from various structural and functional pathways in living organisms by virtue of their specific recognition abilities towards both organic and inorganic materials. Phage display libraries are used to identify peptide biomolecules capable of specifically recognizing and binding organic/inorganic materials of interest with high affinities. Using combinatorial approaches, these molecular recognition elements can be converted into smart hybrid biomaterials and harnessed for biotechnological applications. Herein, we used a commercially available phage display library to identify peptides with specific binding affinity to molybdenite (MoS2) and used them to decorate magnetic NPs. These peptide-coupled NPs could capture MoS2 under a variety of environmental conditions. The same batch of NPs could be re-used multiple times to harvest MoS2, clearly suggesting that this hybrid material was robust and recyclable. The advantages of this smart hybrid biomaterial with respect to its MoS2-binding specificity, robust performance under environmentally challenging conditions and its recyclability suggests its potential application in harvesting MoS2 from tailing ponds and downstream mining processes. PMID- 29463860 TI - The path to metastatic mouse models of colorectal cancer. AB - The study and comprehension of the molecular mechanisms underlying cancer biology strongly rely on mouse modeling. An ideal mouse model should have molecular, histopathological, and etiological characteristics as close as possible to those of the corresponding human tumors. Among solid tumors, colorectal cancer (CRC) is one of the malignancies that best suits reproduction in an animal model: it evolves through a progressive set of molecular events and is generally associated with a precise histopathology and a neat cataloging of stages and grades. The development of refined CRC mouse models over several decades has seen them recently evolve toward sophisticated systems that ever more closely approximate the human pathology, with different models addressing different human CRC subtypes. In particular, a metastatic CRC model has been seen as a "holy grail" in this field, and we describe in this review the path taken to achieve metastatic models and discuss the path forward. PMID- 29463862 TI - Intraoperative head drift and eye movement: two under addressed challenges during cataract surgery. AB - PURPOSE: To objectively measure head drift during cataract surgery, and subjectively simulate eye movements and assess impact on surgical technique. MATERIALS AND METHODS: Twelve consecutively recorded routine cataract operations in the Tennent Institute of Ophthalmology, Gartnavel General Hospital, Glasgow, were reviewed. The speculum was used as a fixed point and correlated with a superimposed virtual ruler to measure maximum head drift in each direction throughout the operations. To simulate intraoperative eye movement, we attached string to the cataract surgical simulator (Eyesi) eye and manually induced abduction and adduction. A calibrated scale secured to the Eyesi head ensured 5 mm eye movements were consistently created. Ophthalmology trainees performed the continuous curvilinear capsulorhexis (CCC) exercise without and with sequential eye movements. Movements were induced every three seconds. Scores were compared using a paired Student's T-test. RESULTS: Mean head drift in the surgical recordings was 3.1 mm medially (range 2-7 mm), 2.9 mm laterally (range 2-4 mm), 2.6 mm superiorly (range 1-5 mm), and 1.9 mm inferiorly (range 1-4 mm). In 11 of 12 cases, the operating microscope had to be adjusted for head drift. Six junior trainees completed the CCC module on the Eyesi without then with eye movements. After introducing eye movements the mean Eyesi score reduced from 92.7 to 76.9 (P = 0.014), 'roundness of rhexis' score reduced from 89.4 to 57.5 (P = 0.020), and trainees operated 17 s faster (P = 0.016). CONCLUSION: This study objectively demonstrates the under-reported clinical scenario of head drift during cataract surgery. By manipulating the Eyesi we have shown that eye movements reduce the quality of cataract surgery. PMID- 29463861 TI - Beyond molecular tumor heterogeneity: protein synthesis takes control. AB - One of the daunting challenges facing modern medicine lies in the understanding and treatment of tumor heterogeneity. Most tumors show intra-tumor heterogeneity at both genomic and proteomic levels, with marked impacts on the responses of therapeutic targets. Therapeutic target-related gene expression pathways are affected by hypoxia and cellular stress. However, the finding that targets such as eukaryotic initiation factor (eIF) 4E (and its phosphorylated form, p-eIF4E) are generally homogenously expressed throughout tumors, regardless of the presence of hypoxia or other cellular stress conditions, opens the exciting possibility that malignancies could be treated with therapies that combine targeting of eIF4E phosphorylation with immune checkpoint inhibitors or chemotherapy. PMID- 29463863 TI - Proposal for a new classification for ocular surface squamous neoplasia. PMID- 29463864 TI - Lateral tarsal strip versus Bick's procedure in correction of eyelid malposition. AB - OBJECTIVES: To compare the functional and anatomical outcomes of lateral tarsal strip (LTS) with Bick's procedure in treatment of eyelid malposition. METHODS: A retrospective, consecutive case series of patients who underwent LTS and Bick's procedure for all types of involutional lower eyelid malposition, at two centers between January 2012 and 2015. Statistical analyses of differences between groups were performed using the Fisher's exact test to compare non-continuous variables and Mann-Whitney U test for continuous variables. RESULTS: A total of 641 procedures (557 LTS and 84 Bick's) were performed on 504 patients (137 bilateral) by 7 consultants and their trainees. The study cohort included 286 males and 218 females. The mean age was 76.2 years (median 78). The mean follow-up was 13.07 months (median 7, range 0.5-58 months). The indications for surgery included ectropion (43.2%), entropion (39.9%), eyelid laxity (12.3%), floppy eyelid syndrome (2.7%), and others (1.9%). At last follow-up, the LTS group achieved 89.1% anatomical success (total + partial correction) compared to 100% in Bick's group (P < 0.001). Functional improvement was 82% and 95% in LTS and Bick's groups, respectively (P = 0.002). Consultants and trainee doctors achieved comparable outcomes within each group. Complications were relatively minor with no major long-term sequelae, nor any statistically significant difference between the two groups in terms of frequency of adverse events (16.9% vs 14.2%, P = 0.929). The reoperation rate was 9% in the LTS group during the study period, compared to none in the Bick's group (P = 0.001). CONCLUSIONS: This study compares the outcomes of the largest reported cohort of eyelid malposition surgery analyzing the two different techniques for lid margin shortening. Bick's procedure achieved statistically significant better anatomical and functional outcomes compared to LTS although the samples were unequal and not randomized. PMID- 29463865 TI - Enhanced Biological Response of AVS-Functionalized Ti-6Al-4V Alloy through Covalent Immobilization of Collagen. AB - This study presents the development of an efficient procedure for covalently immobilizing collagen molecules on AVS-functionalized Ti-6Al-4V samples, and the assessment of the survival and proliferation of cells cultured on these substrates. Activated Vapor Silanization (AVS) is a versatile functionalization technique that allows obtaining a high density of active amine groups on the surface. A procedure is presented to covalently bind collagen to the functional layer using EDC/NHS as cross-linker. The covalently bound collagen proteins are characterized by fluorescence microscopy and atomic force microscopy and their stability is tested. The effect of the cross-linker concentration on the process is assessed. The concentration of the cross-linker is optimized and a reliable cleaning protocol is developed for the removal of the excess of carbodiimide from the samples. The results demonstrate that the covalent immobilization of collagen type I on Ti-6Al-4V substrates, using the optimized protocol, increases the number of viable cells present on the material. Consequently, AVS in combination with the carbodiimide chemistry appears as a robust method for the immobilization of proteins and, for the first time, it is shown that it can be used to enhance the biological response to the material. PMID- 29463866 TI - Hybridized Tungsten Oxide Nanostructures for Food Quality Assessment: Fabrication and Performance Evaluation. AB - Tungsten oxide based micro and nanosized structures possess good capacitance as well as enhanced rate capability. Such properties are useful in various applications including electrochemical supercapacitors. Apart from supercapacitance, WO3 and their 2D integrated structures have been modified using different methods to widen their range of the utility. Modification using layer coating, functionalization with other nanomaterial or molecules are methods that can be used to improve the core structure of WO3. But such modifications often alter electrochemical performance. The effects and outcomes of such modifications incorporated in WO3 structures were studied using electrochemical methods, sensing behavior, and morphological examination. One goal for such modifications was to improve robustness of the WO3 structures apart from any change in supercapacitance performance. After detailed electrochemical analyses of WO3 structures, a preliminary study was performed regarding the feasibility of the WO3 based sensors for food safety applications based on electrochemical detection of hazardous dyes in food. Preliminary results obtained after various electrochemical tests including pulsed voltammetry, cyclic voltammetry, and electrochemical impedance spectroscopy suggest the viability of WO3 structures for food safety applications. PMID- 29463867 TI - Optogenetic Tractography for anatomo-functional characterization of cortico subcortical neural circuits in non-human primates. AB - Dissecting neural circuitry in non-human primates (NHP) is crucial to identify potential neuromodulation anatomical targets for the treatment of pharmacoresistant neuropsychiatric diseases by electrical neuromodulation. How targets of deep brain stimulation (DBS) and cortical targets of transcranial magnetic stimulation (TMS) compare and might complement one another is an important question. Combining optogenetics and tractography may enable anatomo functional characterization of large brain cortico-subcortical neural pathways. For the proof-of-concept this approach was used in the NHP brain to characterize the motor cortico-subthalamic pathway (m_CSP) which might be involved in DBS action mechanism in Parkinson's disease (PD). Rabies-G-pseudotyped and Rabies-G VSVg-pseudotyped EIAV lentiviral vectors encoding the opsin ChR2 gene were stereotaxically injected into the subthalamic nucleus (STN) and were retrogradely transported to the layer of the motor cortex projecting to STN. A precise anatomical mapping of this pathway was then performed using histology-guided high angular resolution MRI tractography guiding accurately cortical photostimulation of m_CSP origins. Photoexcitation of m_CSP axon terminals or m_CSP cortical origins modified the spikes distribution for photosensitive STN neurons firing rate in non-equivalent ways. Optogenetic tractography might help design preclinical neuromodulation studies in NHP models of neuropsychiatric disease choosing the most appropriate target for the tested hypothesis. PMID- 29463868 TI - CD38 promotes pristane-induced chronic inflammation and increases susceptibility to experimental lupus by an apoptosis-driven and TRPM2-dependent mechanism. AB - In this study, we investigated the role of CD38 in a pristane-induced murine model of lupus. CD38-deficient (Cd38-/-) but not ART2-deficient (Art2-/-) mice developed less severe lupus compared to wild type (WT) mice, and their protective phenotype consisted of (i) decreased IFN-I-stimulated gene expression, (ii) decreased numbers of peritoneal CCR2hiLy6Chi inflammatory monocytes, TNF-alpha producing Ly6G+ neutrophils and Ly6Clo monocytes/macrophages, (iii) decreased production of anti-single-stranded DNA and anti-nRNP autoantibodies, and (iv) ameliorated glomerulonephritis. Cd38-/- pristane-elicited peritoneal exudate cells had defective CCL2 and TNF-alpha secretion following TLR7 stimulation. However, Tnf-alpha and Cxcl12 gene expression in Cd38-/- bone marrow (BM) cells was intact, suggesting a CD38-independent TLR7/TNF-alpha/CXCL12 axis in the BM. Chemotactic responses of Cd38-/- Ly6Chi monocytes and Ly6G+ neutrophils were not impaired. However, Cd38-/- Ly6Chi monocytes and Ly6Clo monocytes/macrophages had defective apoptosis-mediated cell death. Importantly, mice lacking the cation channel TRPM2 (Trpm2-/-) exhibited very similar protection, with decreased numbers of PECs, and apoptotic Ly6Chi monocytes and Ly6Clo monocytes/macrophages compared to WT mice. These findings reveal a new role for CD38 in promoting aberrant inflammation and lupus-like autoimmunity via an apoptosis-driven mechanism. Furthermore, given the implications of CD38 in the activation of TRPM2, our data suggest that CD38 modulation of pristane-induced apoptosis is TRPM2-dependent. PMID- 29463869 TI - Angiotensin-converting enzyme inhibitor reduces scar formation by inhibiting both canonical and noncanonical TGF-beta1 pathways. AB - Angiotensin-converting enzyme inhibitors (ACEIs) can improve the fibrotic processes in many internal organs. Recent studies have shown a relationship between ACEI with cutaneous scar formation, although it has not been confirmed, and the underlying mechanism is unclear. In this study, we cultured mouse NIH 3T3 fibroblasts with different concentrations of ACEI. We measured cell proliferation with a Cell Counting Kit-8 and collagen expression with a Sirius Red Collagen Detection Kit. Flow cytometry and western blotting were used to detect transforming growth factor beta1 (TGF-beta1) signaling. We also confirmed the potential antifibrotic activity of ACEI in a rat scar model. ACEI reduced fibroblast proliferation, suppressed collagen and TGF-beta1 expression, and downregulated the phosphorylation of SMAD2/3 and TAK1, both in vitro and in vivo. A microscopic examination showed that rat scars treated with ramipril or losartan were not only narrower than in the controls, but also displayed enhanced re epithelialization and neovascularization, and the formation of organized granulation tissue. These data indicate that ACEI inhibits scar formation by suppressing both TGF-beta1/SMAD2/3 and TGF-beta1/TAK1 pathways, and may have clinical utility in the future. PMID- 29463870 TI - A novel P300 BCI speller based on the Triple RSVP paradigm. AB - A brain-computer interface (BCI) is an advanced human-machine interaction technology. The BCI speller is a typical application that detects the stimulated source-induced EEG signal to identify the expected characters of the subjects. The current mainstream matrix-based BCI speller involves two problems that remain unsolved, namely, gaze-dependent and space-dependent problems. Some scholars have designed gaze-independent and space-independent spelling systems. However, this system still cannot achieve a satisfactory information transfer rate (ITR). In this paper, we propose a novel triple RSVP speller with gaze-independent and space-independent characteristics and higher ITR. The triple RSVP speller uses rapid serial visual presentation (RSVP) paradigm, each time presents three different characters, and each character is presented three times to increase the ITR. The results of the experiments show the triple RSVP speller online average accuracy of 0.790 and average online ITR of 20.259 bit/min, where the system spelled at a speed of 10 s per character, and the stimulus presentation interface is a 90 * 195 pixel rectangle. Thus, the triple RSVP speller can be integrated into mobile smart devices (such as smartphones, smart watches, and others).

AB - Hypertension and diabetes are associated with a risk of cardiovascular disease. Clonidine is currently used as a fourth-line drug therapy for hypertension because of its rebound hypertensive effect and short half-life. The purpose of this study was to investigate the combined effect of an antihypertensive drug (clonidine) and a G-protein-coupled receptor kinase 2 (GRK2) inhibitor on rebound hypertension and endothelial dysfunction. The clonidine and/or GRK2 inhibitor were administered by continuous infusion for 14 days by using an osmotic pump that was implanted subcutaneously. To test the effects of GRK2 inhibitotr, we measured blood pressure by using a tail-cuff system in diabetic mice in which rebound hypertension was induced by withdrawal after clonidine treatment and measured vascular responses in isolated aortas from these mice. The mice were then euthanized 7 days later. We observed that, in diabetes mellitus (DM) mice, blood pressure began to decline after 3 days of clonidine or clonidine + GRK2 inhibitor infusion. However, 15 days after initiation of treatment, the blood pressure of the clonidine only-treated DM mice began to increase and resulted in a high final blood pressure. At 21 days, clonidine withdrawal triggered rebound hypertension together with impaired endothelium-dependent relaxation, increased GRK2 activity, and reduced Akt/endothelial NO synthase (eNOS)/NO production in aortas. Conversely, withdrawal of the combination clonidine/GRK2-inhibitor treatment did not cause rebound hypertension, and normal induction of endothelium dependent relaxation, decreased GRK2 activity, and increased Akt/eNOS were observed in aortas from DM mice. These results suggest that suppression of GRK2 activity affects rebound hypertension-associated vascular endothelial dysfunction by targeting the Akt/eNOS signaling pathway.

AB - The range of potential applications of compact laser-plasma ion sources motivates the development of new acceleration schemes to increase achievable ion energies and conversion efficiencies. Whilst the evolving nature of laser-plasma interactions can limit the effectiveness of individual acceleration mechanisms, it can also enable the development of hybrid schemes, allowing additional degrees of control on the properties of the resulting ion beam. Here we report on an experimental demonstration of efficient proton acceleration to energies exceeding 94 MeV via a hybrid scheme of radiation pressure-sheath acceleration in an ultrathin foil irradiated by a linearly polarised laser pulse. This occurs via a double-peaked electrostatic field structure, which, at an optimum foil thickness, is significantly enhanced by relativistic transparency and an associated jet of super-thermal electrons. The range of parameters over which this hybrid scenario occurs is discussed and implications for ion acceleration driven by next generation, multi-petawatt laser facilities are explored. PMID- 29463873 TI - Induction of micronuclei by four cytostatic compounds in human hematopoietic stem cells and human lymphoblastoid TK6 cells. AB - For mutagenicity testing, primary lymphocytes or mammalian cell lines are employed. However, the true target for carcinogenic action of mutagenic chemicals may be stem cells. Since hematopoietic cancers induced by chemical agents originate at the hematopoietic stem cell (HSC) stage and since one of the side effects of chemotherapeutic cancer treatment is the induction of secondary tumors, often leukemias, HSC may be a suitable cell system. We compared the sensitivity of HSC with the genotoxicity testing cell line TK6 for chromosomal mutations. HSC were less sensitive than TK6 cells for the genotoxic effects of the model genotoxins and chemotherapeutic agents doxorubicin, vinblastine, methyl methanesulfonate (MMS) and equally sensitive for mitomycin C (MMC). However, loss of viability after mitomycin C treatment was higher in HSC than in TK6 cells. Among the factors that may influence sensitivity for genomic damage, the generation or response to reactive oxygen species (ROS) and the effectiveness of DNA damage response can be discussed. Here we show that HSC can be used in a standard micronucleus test protocol for chromosomal mutations and that their sensitivity was not higher than that of a classical testing cell line. PMID- 29463874 TI - Prominent exostosis projecting from the occipital squama more substantial and prevalent in young adult than older age groups. AB - Recently we reported the development of prominent exostosis young adults' skulls (41%; 10-31 mm) emanating from the external occipital protuberance (EOP). These findings contrast existing reports that large enthesophytes are not seen in young adults. Here we show that a combination sex, the degree of forward head protraction (FHP) and age predicted the presence of enlarged EOP (EEOP) (n = 1200, age 18-86). While being a male and increased FHP had a positive effect on prominent exostosis, paradoxically, increase in age was linked to a decrease in enthesophyte size. Our latter findings provide a conundrum, as the frequency and severity of degenerative skeletal features in humans are associated typically with aging. Our findings and the literature provide evidence that mechanical load plays a vital role in the development and maintenance of the enthesis (insertion) and draws a direct link between aberrant loading of the enthesis and related pathologies. We hypothesize EEOP may be linked to sustained aberrant postures associated with the emergence and extensive use of hand-held contemporary technologies, such as smartphones and tablets. Our findings raise a concern about the future musculoskeletal health of the young adult population and reinforce the need for prevention intervention through posture improvement education. PMID- 29463875 TI - Proliferation and apoptosis of T lymphocytes in patients with bipolar disorder. AB - The aim of the study was to evaluate proliferation capacity and susceptibility to apoptosis of T lymphocytes of patients with bipolar disorder (BD) and to investigate in vitro influence of two standard mood stabilizers: lithium and valproic acid on these parameters using flow cytometry. Our results show that T lymphocytes of BD patients, especially those treated with lithium, have reduced proliferation capacity compared to healthy people. In vitro studies showed that valproic acid reduces the number of cell divisions and percentages of proliferating cells regardless of health status but mainly in very high dose, while lithium has no significant influence on proliferation capacity of patients' T lymphocytes. Lymphocytes of BD patients are also more prone to apoptosis compared with healthy individuals which is related to high expression of Bax, a pro-apoptotic protein. In vitro lithium protected patients' lymphocytes from apoptosis proportionally to dose used. Valproic acid protected lymphocytes of patients from apoptosis mainly in therapeutic concentration. Our results show that mood stabilizers used to prevent relapses of the disease have anti-apoptotic effect on T lymphocytes of BD patients but they are not able to improve their proliferation capacity.

PMID- 29463877 TI - Cinnamaldehyde accelerates wound healing by promoting angiogenesis via up regulation of PI3K and MAPK signaling pathways. AB - The bark of Cinnamomum cassia (C. cassia) has been used for the management of coronary heart disease (CHD) and diabetes mellitus. C. cassia may target the vasculature, as it stimulates angiogenesis, promotes blood circulation and wound healing. However, the active components and working mechanisms of C. cassia are not fully elucidated. The Shexiang Baoxin pill (SBP), which consists of seven medicinal materials, including C. cassia etc., is widely used as a traditional Chinese patent medicine for the treatment of CHD. Here, 22 single effective components of SBP were evaluated against the human umbilical vein endothelial cells (HUVECs). We demonstrated that in HUVECs, cinnamaldehyde (CA) stimulated proliferation, migration, and tube formation. CA also activated the phosphatidylinositol 3-kinase (PI3K) and mitogen-activated protein kinase (MAPK) pathways. Furthermore, the secretion of vascular endothelial growth factor (VEGF) from HUVECs was increased by CA. In vivo, CA partially restored intersegmental vessels in zebrafish pretreated with PTK787, which is a selective inhibitor for vascular endothelial growth factor receptor (VEGFR). CA also showed pro angiogenic efficacy in the Matrigel plug assay. Additionally, CA attenuated wound sizes in a cutaneous wound model, and elevated VEGF protein and CD31-positive vascular density at the margin of these wounds. These results illustrate that CA accelerates wound healing by inducing angiogenesis in the wound area. The potential mechanism involves activation of the PI3K/AKT and MAPK signaling pathways. Such a small non-peptide molecule may have clinical applications for promoting therapeutic angiogenesis in chronic diabetic wounds and myocardial infarction. PMID- 29463878 TI - Glutathione peroxidase 4 overexpression inhibits ROS-induced cell death in diffuse large B-cell lymphoma. AB - Regulation of oxidative stress and redox systems has important roles in carcinogenesis and cancer progression, and for this reason has attracted much attention as a new area of cancer therapeutic targets. Glutathione peroxidase 4 (GPX4), an antioxidant enzyme, has biological important functions such as signaling cell death by suppressing peroxidation of membrane phospholipids. However, few studies exist on the expression and clinical relevance of GPX4 in malignant lymphomas such as diffuse large B-cell lymphoma. In this study, we assessed the expression of GPX4 immunohistochemically. GPX4 was expressed in 35.5% (33/93) cases of diffuse large B-cell lymphoma. The GPX4-positive group had poor overall survival (P = 0.0032) and progression-free survival (P = 0.0004) compared with those of the GPX4-negative group. In a combined analysis of GPX4 and 8-hydroxydeoxyguanosine (8-OHdG), an oxidative stress marker, there was a negative correlation between GPX4 and 8-hydroxydeoxyguanosine (P = 0.0009). The GPX4-positive and 8-hydroxydeoxyguanosine-negative groups had a significantly worse prognosis than the other groups in both overall survival (P = 0.0170) and progression-free survival (P = 0.0005). These results suggest that the overexpression of GPX4 is an independent prognostic predictor in diffuse large B cell lymphoma. Furthermore, in vitro analysis demonstrated that GPX4 overexpressing cells were resistant to reactive oxygen species-induced cell death (P = 0.0360). Conversely, GPX4-knockdown cells were sensitive to reactive oxygen species-induced cell death (P = 0.0111). From these data, we conclude that GPX4 regulates reactive oxygen species-induced cell death. Our results suggest a novel therapeutic strategy using the mechanism of ferroptosis, as well as a novel prognostic predictor of diffuse large B-cell lymphoma. PMID- 29463880 TI - Salvaging the supernatant: next generation cytopathology for solid tumor mutation profiling. AB - With the expanding role of targeted therapy in patients with solid tumors, pathologists face the daunting task of having to maximize limited volume tissue obtained by fine needle aspiration for a variety of molecular tests. While most molecular studies on fine needle aspiration samples have been reported using cellular material, recent studies have shown that a substantial amount of DNA can be retrieved from the supernatant fluid of aspirate needle rinses after cell pelleting for cytospin or cell block preparations. In routine clinical workflow, the supernatant is discarded; however this fluid may provide a complementary source of DNA for tumor mutational profiling. In this study, we evaluated the post-centrifuged supernatant from 25 malignant and 10 benign fine needle aspiration needle rinses. The mean and median DNA yields from the supernatants were 445 ng and 176.4 ng (range, 15.1-2958 ng), respectively. Next generation sequencing using the Ion AmpliSeq Cancer Hotspot Panel v2 detected somatic mutations in all 25 malignant samples. No mutations were detected in any of the benign samples tested. When available, mutations detected in the supernatant fluid were compared to the next generation sequencing analysis performed on a prior or concurrent surgical specimen from the same patient and showed 100% concordance. In a subset of cases (n = 19) mutations in EGFR, KRAS, BRAF, PIK3CA, and NRAS were successfully confirmed by droplet digital PCR, providing an orthogonal platform for mutation analysis. In summary, in this study we show that post centrifuged supernatants from fine needle aspiration needle rinses can provide a robust substrate for expanded mutation profiling by next generation sequencing, as well as hotspot mutation testing by droplet digital PCR. The ability to detect somatic mutations from otherwise discarded supernatant fluids offers the ability to triage and effectively utilize limited volume fine needle aspiration samples when multiple molecular tests are requested, without the need to re-biopsy for additional tissue samples. PMID- 29463879 TI - Redox control of vascular smooth muscle cell function and plasticity. AB - Vascular smooth muscle cells (SMC) play a major role in vascular diseases, such as atherosclerosis and hypertension. It has long been established in vitro that contractile SMC can phenotypically switch to function as proliferative and/or migratory cells in response to stimulation by oxidative stress, growth factors, and inflammatory cytokines. Reactive oxygen species (ROS) are oxidative stressors implicated in driving vascular diseases, shifting cell bioenergetics, and increasing SMC proliferation, migration, and apoptosis. In this review, we summarize our current knowledge of how disruptions to redox balance can functionally change SMC and how this may influence vascular disease pathogenesis. Specifically, we focus on our current understanding of the role of vascular nicotinamide adenine dinucleotide phosphate (NADPH) oxidases (NOX) 1, 4, and 5 in SMC function. We also review the evidence implicating mitochondrial fission in SMC phenotypic transitions and mitochondrial fusion in maintenance of SMC homeostasis. Finally, we discuss the importance of the redox regulation of the soluble guanylate cyclase (sGC)-cyclic guanosine monophosphate (cGMP)-protein kinase G (PKG) pathway as a potential oxidative and therapeutic target for regulating SMC function. PMID- 29463881 TI - Stroma modifies relationships between risk factor exposure and age-related epithelial involution in benign breast. AB - Delayed age-related lobular involution has been previously associated with elevated breast cancer risk. However, intraindividual variability in epithelial involution status within a woman is undefined. We developed a novel measure of age-related epithelial involution, density of epithelial nuclei in epithelial areas using digital image analysis in combination with stromal characteristics (percentage of section area comprising stroma). Approximately 1800 hematoxylin and eosin stained sections of benign breast tissue were evaluated from 416 participants having breast surgery for cancer or benign conditions. Two to sixteen slides per woman from different regions of the breast were studied. Epithelial involution status varied within a woman and as a function of stromal area. Percentage stromal area varied between samples from the same woman (median difference between highest and lowest stromal area within a woman was 7.5%, but ranged from 0.01 to 86.7%). Restricting to women with at least 10% stromal area (N = 317), epithelial nuclear density decreased with age (-637.1 cells/mm2 per decade of life after age 40, p < 0.0001), increased with mammographic density (457.8 cells/mm2 per increasing BI-RADs density category p = 0.002), and increased non-significantly with recent parity, later age at first pregnancy, and longer and more recent oral contraceptive use. These associations were attenuated in women with mostly fat samples (<10% stroma (N = 99)). Thirty-one percent of women evaluated had both adequate stroma (>=10%) and mostly fat (<10% stroma) regions of breast tissue, with the probability of having both types increasing with the number breast tissue samplings. Several breast cancer risk factors are associated with elevated age-related epithelial content, but associations depend upon stromal context. Stromal characteristics appear to modify relationships between risk factor exposures and breast epithelial involution. PMID- 29463883 TI - Frequent and differential mutations of the CYLD gene in basal cell salivary neoplasms: linkage to tumor development and progression. AB - Basal cell salivary neoplasms display similar cyto-morphologic features and are classified into adenoma and adenocarcinoma based on the presence or absence of tumor invasion at diagnosis. These neoplasms also share considerable phenotypic resemblance and co-exist with certain dermal adnexal tumors harboring the CYLD gene mutations inferring common genetic association. We sequenced the CYLD gene in both basal cell adenomas and adenocarcinomas and correlated the findings with CYLD, NF-kappaB, and beta-catenin expression levels and clinicopathologic factors. Twenty mutations were identified and comprised of 3 synonymous and 17 non-synonymous (missense) types involving the coding exons of the CYLD gene. Mutations in exons 9-11 were identified in both adenomas and adenocarcinomas, while mutations in exons 12-20, encoding the USP domain, were exclusively found in carcinomas. Although no significant correlation between CYLD mutations and expression levels of CYLD, NF-kappaB, and beta-catenin or clinicopathologic parameters was found, basal cell adenocarcinomas with multiple mutations showed reduction in CYLD protein expression and pursued aggressive clinical behavior. Our study revealed high incidence and sequential CYLD mutations in both basal cell adenoma and adenocarcinoma supporting a single neoplastic continuum for their evolution and provides evidence for potential diagnostic and therapeutic utility. PMID- 29463882 TI - The genetics of recurrent hydatidiform moles: new insights and lessons from a comprehensive analysis of 113 patients. AB - Hydatidiform mole is an aberrant human pregnancy characterized by early embryonic arrest and excessive trophoblastic proliferation. Recurrent hydatidiform moles are defined by the occurrence of at least two hydatidiform moles in the same patient. Fifty to eighty percent of patients with recurrent hydatidiform moles have biallelic pathogenic variants in NLRP7 or KHDC3L. However, in the remaining patients, the genotypic types of the moles are unknown. We characterized 80 new hydatidiform mole tissues, 57 of which were from patients with no mutations in the known genes, and we reviewed the genotypes of a total of 123 molar tissues. We also reviewed mutation analysis in 113 patients with recurrent hydatidiform moles. While all hydatidiform moles from patients with biallelic NLRP7 or KHDC3L mutations are diploid biparental, we demonstrate that those from patients without mutations are highly heterogeneous and only a small minority of them are diploid biparental (8%). The other mechanisms that were found to recur in patients without mutations are diploid androgenetic monospermic (24%) and triploid dispermic (32%); the remaining hydatidiform moles were misdiagnosed as moles due to errors in the analyses and/or their unusual mechanisms. We compared three parameters of genetic susceptibility in patients with and without mutations and show that patients without mutations are mostly from non-familial cases, have fewer reproductive losses, and more live births. Our data demonstrate that patients with recurrent hydatidiform moles and no mutations in the known genes are, in general, different from those with mutations; they have a milder genetic susceptibility and/or a multifactorial etiology underlying their recurrent hydatidiform moles. Categorizing these patients according to the genotypic types of their recurrent hydatidiform moles may facilitate the identification of novel genes for this entity. PMID- 29463884 TI - Tumor-infiltrating lymphocytes and ductal carcinoma in situ of the breast: friends or foes? AB - In the past three decades, the detection rate of ductal carcinoma in situ of the breast has dramatically increased due to breast screening programs. As a consequence, about 20% of all breast cancer cases are detected in this early in situ stage. Some ductal carcinoma in situ cases will progress to invasive breast cancer, while other cases are likely to have an indolent biological behavior. The presence of tumor-infiltrating lymphocytes is seen as a promising prognostic and predictive marker in invasive breast cancer, mainly in HER2-positive and triple negative subtypes. Here, we summarize the current understanding regarding immune infiltrates in invasive breast cancer and highlight recent observations regarding the presence and potential clinical significance of such immune infiltrates in patients with ductal carcinoma in situ. The presence of tumor-infiltrating lymphocytes, their numbers, composition, and potential relationship with genomic status will be discussed. Finally, we propose that a combination of genetic and immune markers may better stratify ductal carcinoma in situ subtypes with respect to tumor evolution. PMID- 29463885 TI - Machine learning for the meta-analyses of microbial pathogens' volatile signatures. AB - Non-invasive and fast diagnostic tools based on volatolomics hold great promise in the control of infectious diseases. However, the tools to identify microbial volatile organic compounds (VOCs) discriminating between human pathogens are still missing. Artificial intelligence is increasingly recognised as an essential tool in health sciences. Machine learning algorithms based in support vector machines and features selection tools were here applied to find sets of microbial VOCs with pathogen-discrimination power. Studies reporting VOCs emitted by human microbial pathogens published between 1977 and 2016 were used as source data. A set of 18 VOCs is sufficient to predict the identity of 11 microbial pathogens with high accuracy (77%), and precision (62-100%). There is one set of VOCs associated with each of the 11 pathogens which can predict the presence of that pathogen in a sample with high accuracy and precision (86-90%). The implemented pathogen classification methodology supports future database updates to include new pathogen-VOC data, which will enrich the classifiers. The sets of VOCs identified potentiate the improvement of the selectivity of non-invasive infection diagnostics using artificial olfaction devices. PMID- 29463886 TI - A set of regulatory genes co-expressed in embryonic human brain is implicated in disrupted speech development. AB - Genetic investigations of people with impaired development of spoken language provide windows into key aspects of human biology. Over 15 years after FOXP2 was identified, most speech and language impairments remain unexplained at the molecular level. We sequenced whole genomes of nineteen unrelated individuals diagnosed with childhood apraxia of speech, a rare disorder enriched for causative mutations of large effect. Where DNA was available from unaffected parents, we discovered de novo mutations, implicating genes, including CHD3, SETD1A and WDR5. In other probands, we identified novel loss-of-function variants affecting KAT6A, SETBP1, ZFHX4, TNRC6B and MKL2, regulatory genes with links to neurodevelopment. Several of the new candidates interact with each other or with known speech-related genes. Moreover, they show significant clustering within a single co-expression module of genes highly expressed during early human brain development. This study highlights gene regulatory pathways in the developing brain that may contribute to acquisition of proficient speech. PMID- 29463887 TI - Dipyrimicin A and B, microbial compounds isolated from Amycolatopsis sp. K16 0194. AB - In a search for compounds interacting with ergosterol resin, a new compound named dipyrimicin B was isolated from a rare actinomycete strain, Amycolatopsis sp. K16 0194. In addition, another analog, dipyrimicin A, which does not interact with the resin, was also discovered. The structures of the two dipyrimicins were established by comprehensive 1D and 2D NMR and MS analyses and found to contain a unique core structure, a 2,2'-bipyridine skeleton. Dipyrimicin A showed strong antimicrobial and cytotoxic activity, whereas dipyrimicin B displayed distinctly poor antimicrobial and cytotoxic activities. PMID- 29463888 TI - Furanoaustinol and 7-acetoxydehydroaustinol: new meroterpenoids from a marine derived fungal strain Penicillium sp. SF-5497. AB - Two new meroterpenoid-type fungal metabolites, furanoaustinol (1) and 7 acetoxydehydroaustinol (2), were isolated from the ethyl acetate extract of a marine-derived fungal strain Penicillium sp. SF-5497, along with eight (3-10) known meroterpenoids. Their structures were elucidated mainly based on the analysis of their NMR (1D and 2D) and MS data. Particularly, the novel meroterpenoid, furanoaustinol (1), belonging to the austin group, was identified to possess an unprecedented hexacyclic ring system. Biological evaluation of these compounds revealed that furanoaustinol (1) weakly inhibited the activity of protein tyrosine phosphatase 1B in a dose-dependent manner with an IC50 value of 77.2 MUM. In addition, 7-acetoxydehydroaustinol (2) and four other known meroterpenoids (5, 7, 9, and 10) weakly suppressed the overproduction of nitric oxide in lipopolysaccharide-challenged BV2 microglial cells with IC50 values of 61.0, 30.1, 58.3, 37.6, and 40.2 MUM, respectively. PMID- 29463889 TI - Rational design of syn-safencin, a novel linear antimicrobial peptide derived from the circular bacteriocin safencin AS-48. AB - Bacteriocins hold unprecedented promise as a largely untapped source of antibiotic alternatives in the age of multidrug resistance. Here, we describe the first approach to systematically design variants of a novel AS-48 bacteriocin homologue, which we have termed safencin AS-48, from Bacillus safensis, to gain insights into engineering improved activity of bacteriocins. A library of synthetic peptides in which systematic amino acid substitutions to vary the periodicity and abundance of polar, acidic, aliphatic, and hydrophobic residues were generated for a total of 96 novel peptide variants of a single bacteriocin candidate. Using this method, we identified nine synthetic safencin (syn safencin) variants with broad and potent antimicrobial activities with minimal inhibitory concentrations (MIC) as low as 250 nM against E. coli, P. aeruginosa, X. axonopodis, and S. pyogenes with minimal cytotoxicity to mammalian cells. It is anticipated that the strategies we have developed will serve as general guides for tuning the specificity of a given natural bacteriocin compound for therapeutic specificity. PMID- 29463890 TI - Iron and phosphorus deprivation induce sociality in the marine bloom-forming cyanobacterium Trichodesmium. AB - Trichodesmium spp. are diazotrophic cyanobacteria that exist as single filaments (trichomes) and as macroscopic colonies of varying shapes formed by aggregating trichomes. The causes and dynamics of colony formation and disassociation are not yet elucidated. we demonstrate that limited availability of dissolved phosphorus (P) or iron (Fe) stimulated trichome mobility and induced colony formation in Trichodesmium erythraeum IMS101 cultures. The specific nutrient limitation differentially affected the rate of colony formation and morphology of the colonies. Fe starvation promoted rapid colony formation (10-48 h from depletion) while 5-7 days were required for colonies to form in P-depleted cultures. Video analyses confirmed that the probability of trichomes to cluster increased from 12 to 35% when transferred from nutrient replete to Fe-depleted conditions. Moreover, the probability for Fe-depleted aggregates to remain colonial increased to 50% from only 10% in nutrient replete cultures. These colonies were also characterized by stronger attachment forces between the trichomes. Enrichment of nutrient-depleted cultures with the limited nutrient-stimulated colony dissociation into single trichomes. We postulate that limited P and Fe availability enhance colony formation of Trichodesmium and primarily control the abundance and distribution of its different morphologies in the nutrient-limited surface ocean. PMID- 29463891 TI - Specialized plant biochemistry drives gene clustering in fungi. AB - The fitness and evolution of prokaryotes and eukaryotes are affected by the organization of their genomes. In particular, the physical clustering of genes can coordinate gene expression and can prevent the breakup of co-adapted alleles. Although clustering may thus result from selection for phenotype optimization and persistence, the impact of environmental selection pressures on eukaryotic genome organization has rarely been systematically explored. Here, we investigated the organization of fungal genes involved in the degradation of phenylpropanoids, a class of plant-produced secondary metabolites that mediate many ecological interactions between plants and fungi. Using a novel gene cluster detection method, we identified 1110 gene clusters and many conserved combinations of clusters in a diverse set of fungi. We demonstrate that congruence in genome organization over small spatial scales is often associated with similarities in ecological lifestyle. Additionally, we find that while clusters are often structured as independent modules with little overlap in content, certain gene families merge multiple modules into a common network, suggesting they are important components of phenylpropanoid degradation strategies. Together, our results suggest that phenylpropanoids have repeatedly selected for gene clustering in fungi, and highlight the interplay between genome organization and ecological evolution in this ancient eukaryotic lineage. PMID- 29463892 TI - Microbial cycling of isoprene, the most abundantly produced biological volatile organic compound on Earth. AB - Isoprene (2-methyl-1,3-butadiene), the most abundantly produced biogenic volatile organic compound (BVOC) on Earth, is highly reactive and can have diverse and often detrimental atmospheric effects, which impact on climate and health. Most isoprene is produced by terrestrial plants, but (micro)algal production is important in aquatic environments, and the relative bacterial contribution remains unknown. Soils are a sink for isoprene, and bacteria that can use isoprene as a carbon and energy source have been cultivated and also identified using cultivation-independent methods from soils, leaves and coastal/marine environments. Bacteria belonging to the Actinobacteria are most frequently isolated and identified, and Proteobacteria have also been shown to degrade isoprene. In the freshwater-sediment isolate, Rhodococcus strain AD45, initial oxidation of isoprene to 1,2-epoxy-isoprene is catalyzed by a multicomponent isoprene monooxygenase encoded by the genes isoABCDEF. The resultant epoxide is converted to a glutathione conjugate by a glutathione S-transferase encoded by isoI, and further degraded by enzymes encoded by isoGHJ. Genome sequence analysis of actinobacterial isolates belonging to the genera Rhodococcus, Mycobacterium and Gordonia has revealed that isoABCDEF and isoGHIJ are linked in an operon, either on a plasmid or the chromosome. In Rhodococcus strain AD45 both isoprene and epoxy-isoprene induce a high level of transcription of 22 contiguous genes, including isoABCDEF and isoGHIJ. Sequence analysis of the isoA gene, encoding the large subunit of the oxygenase component of isoprene monooxygenase, from isolates has facilitated the development of PCR primers that are proving valuable in investigating the ecology of uncultivated isoprene-degrading bacteria. PMID- 29463893 TI - Consistent changes in the taxonomic structure and functional attributes of bacterial communities during primary succession. AB - Ecologists have long studied primary succession, the changes that occur in biological communities after initial colonization of an environment. Most of this work has focused on succession in plant communities, laying the conceptual foundation for much of what we currently know about community assembly patterns over time. Because of their prevalence and importance in ecosystems, an increasing number of studies have focused on microbial community dynamics during succession. Here, we conducted a meta-analysis of bacterial primary succession patterns across a range of distinct habitats, including the infant gut, plant surfaces, soil chronosequences, and aquatic environments, to determine whether consistent changes in bacterial diversity, community composition, and functional traits are evident over the course of succession. Although these distinct habitats harbor unique bacterial communities, we were able to identify patterns in community assembly that were shared across habitat types. We found an increase in taxonomic and functional diversity with time while the taxonomic composition and functional profiles of communities became less variable (lower beta diversity) in late successional stages. In addition, we found consistent decreases in the rRNA operon copy number and in the high-efficient phosphate assimilation process (Pst system) suggesting that reductions in resource availability during succession select for taxa adapted to low-resource conditions. Together, these results highlight that, like many plant communities, microbial communities also exhibit predictable patterns during primary succession. PMID- 29463894 TI - Coral bleaching from a single cell perspective. AB - Ocean warming is resulting in increased occurrence of mass coral bleaching; a response in which the intracellular algal endosymbionts (Symbiodinium sp.) are expelled from the coral host due to physiological stress. This detrimental process is often attributed to overproduction of reactive oxygen species (ROS) that leak out of the endosymbionts and causes damage to the host cell, though direct evidence validating this link is limited. Here, for the first time, we used confocal microscopy and fluorescent dyes to investigate if endosymbiont ROS production significantly and predictably affects physiological parameters in its host cell. Heat treatment resulted in a 60% reduction in coral symbiont density, a ~70% increase in median endosymbiont ROS and a small reduction in photosystem efficiency (FV/FM, 11%), indicating absence of severe light stress. Notably, no other physiological parameters were affected in either endosymbionts or host cells, including reduced glutathione and ROS-induced lipid peroxidation. Taken together, the increase in endosymbiont ROS could not be linked to physiological damage in either partner, suggesting that oxidative stress is unlikely to have been the driver for symbiont expulsion in this study. PMID- 29463895 TI - Cryptophyta as major bacterivores in freshwater summer plankton. AB - Small bacterivorous eukaryotes play a cardinal role in aquatic food webs and their taxonomic classification is currently a hot topic in aquatic microbial ecology. Despite increasing interest in their diversity, core questions regarding predator-prey specificity remain largely unanswered, e.g., which heterotrophic nanoflagellates (HNFs) are the main bacterivores in freshwaters and which prokaryotes support the growth of small HNFs. To answer these questions, we fed natural communities of HNFs from Rimov reservoir (Czech Republic) with five different bacterial strains of the ubiquitous betaproteobacterial genera Polynucleobacter and Limnohabitans. We combined amplicon sequencing and catalyzed reporter deposition fluorescence in situ hybridization (CARD-FISH) targeting eukaryotic 18 S rRNA genes to track specific responses of the natural HNF community to prey amendments. While amplicon sequencing provided valuable qualitative data and a basis for designing specific probes, the number of reads was insufficient to accurately quantify certain eukaryotic groups. We also applied a double-hybridization technique that allows simultaneous phylogenetic identification of both predator and prey. Our results show that community composition of HNFs is strongly dependent upon prey type. Surprisingly, Cryptophyta were the most abundant bacterivores, although this phylum has been so far assumed to be mainly autotrophic. Moreover, the growth of a small lineage of Cryptophyta (CRY1 clade) was strongly stimulated by one Limnohabitans strain in our experiment. Thus, our study is the first report that colorless Cryptophyta are major bacterivores in summer plankton samples and can play a key role in the carbon transfer from prokaryotes to higher trophic levels.

AB - Wind conditions strongly affect migratory costs and shape flyways and detours for many birds, especially soaring birds. However, whether winds also influence individual variability in migratory choices is an unexplored question. Cory's shearwaters (Calonectris borealis) exhibit migratory flexibility, changing non breeding destination across the Atlantic Ocean within and between years. Here, we investigated how wind dynamics affect the spatiotemporal migratory behaviour and whether they influence individual choices of non-breeding destination. We analysed 168 GLS tracks of migratory Cory's shearwaters over five years in relation to concurrent wind data. We found no evidence for an association of the use of specific paths or destinations with particular wind conditions. Our results suggest that shearwaters deliberately choose their non-breeding destination, even when the choice entails longer distances and higher energetic costs for displacement due to unfavourable wind conditions en route. Favourable winds trigger migration only when directed towards specific areas but not to others. Despite their dependence on wind for dynamic soaring, Cory's shearwaters show a high individuality in migratory behaviour that cannot be explained by individual birds encountering different meteorological conditions at departure or during migratory movements.

PMID- 29463898 TI - Uncoupling therapeutic from immunotherapy-related adverse effects for safer and effective anti-CTLA-4 antibodies in CTLA4 humanized mice. AB - Anti-CTLA-4 monoclonal antibodies (mAbs) confer a cancer immunotherapeutic effect (CITE) but cause severe immunotherapy-related adverse events (irAE). Targeting CTLA-4 has shown remarkable long-term benefit and thus remains a valuable tool for cancer immunotherapy if the irAE can be brought under control. An animal model, which recapitulates clinical irAE and CITE, would be valuable for developing safer CTLA-4-targeting reagents. Here, we report such a model using mice harboring the humanized Ctla4 gene. In this model, the clinically used drug, Ipilimumab, induced severe irAE especially when combined with an anti-PD-1 antibody; whereas another mAb, L3D10, induced comparable CITE with very mild irAE under the same conditions. The irAE corresponded to systemic T cell activation and resulted in reduced ratios of regulatory to effector T cells (Treg/Teff) among autoreactive T cells. Using mice that were either homozygous or heterozygous for the human allele, we found that the irAE required bi-allelic engagement, while CITE only required monoallelic engagement. As with the immunological distinction for monoallelic vs bi-allelic engagement, we found that bi-allelic engagement of the Ctla4 gene was necessary for preventing conversion of autoreactive T cells into Treg cells. Humanization of L3D10, which led to loss of blocking activity, further increased safety without affecting the therapeutic effect. Taken together, our data demonstrate that complete CTLA-4 occupation, systemic T cell activation and preferential expansion of self-reactive T cells are dispensable for tumor rejection but correlate with irAE, while blocking B7 CTLA-4 interaction impacts neither safety nor efficacy of anti-CTLA-4 antibodies. These data provide important insights for the clinical development of safer and potentially more effective CTLA-4-targeting immunotherapy.

PMID- 29463900 TI - Modifications and functional genomics of human transfer RNA. AB - Transfer RNA (tRNA) is present at tens of millions of transcripts in a human cell and is the most abundant RNA in moles among all cellular RNAs. tRNA is also the most extensively modified RNA with, on an average, 13 modifications per molecule. The primary function of tRNA as the adaptor of amino acids and the genetic code in protein synthesis is well known. tRNA modifications play multi-faceted roles in decoding and other cellular processes. The abundance, modification, and aminoacylation (charging) levels of tRNAs contribute to mRNA decoding in ways that reflect the cell type and its environment; however, how these factors work together to maximize translation efficiency remains to be understood. tRNAs also interact with many proteins not involved in translation and this may coordinate translation activity and other processes in the cell. This review focuses on the modifications and the functional genomics of human tRNA and discusses future perspectives on the explorations of human tRNA biology. PMID- 29463902 TI - Upregulation of SOX2-activated lncRNA ANRIL promotes nasopharyngeal carcinoma cell growth. AB - Recent molecularly targeted approaches have gained advances in nasopharyngeal carcinoma treatment. However, the estimated five-year survival rate has not met the desired degree of improvement. Here, we report that upregulation of the expression of the SOX2-activated lncRNA ANRIL is involved in nasopharyngeal carcinoma. ANRIL has been found to be upregulated in clinical nasopharyngeal carcinoma. Using genetic approaches targeting ANRIL in nasopharyngeal carcinoma cells, we found that the knockdown of ANRIL inhibits cell proliferation in vitro and in vivo. Mechanistically, SOX2 binds with ANRIL and increases its RNA level, which upregulates beta-catenin signalling, resulting in enhanced nasopharyngeal carcinoma tumourigenesis. Expression levels of ANRIL are positively correlated with SOX2 and beta-catenin in clinical nasopharyngeal carcinoma samples. Our findings demonstrate that the SOX2-ANRIL-beta-catenin axis plays a critical role in nasopharyngeal carcinoma proliferation and provide a potential therapeutic approach for nasopharyngeal carcinoma patients. PMID- 29463901 TI - Poly(ADP-ribose) mediates asymmetric division of mouse oocyte. AB - Before fertilization, mammalian oocyte undergoes an asymmetric division which depends on eccentric positioning of the spindle at the oocyte cortex to form a polar body and an egg. Since the centriole is absent and, as a result, the polar array microtubules are not fully developed in oocytes, microtubules have seldom been considered as required for eccentric positioning of the spindle, while actin related forces have instead been proposed to be primarily responsible for this process. However, the existing models are largely conflicting and the underlying mechanism of asymmetric division is still elusive. Here we show that poly(ADP ribose) (PAR) is enriched at mouse oocyte cortical area throughout meiosis. Specific removal of cortical PAR results in an ectopic spindle and a failure of asymmetric division. During spindle migration, when the spindle deviates from the center of oocyte by a pushing force of cytoplasmic actin, the short polar array microtubules emanating from the juxtacortical spindle pole extend to the cortex and penetrate into cortical PAR, docking and stabilizing the spindle at the cortex which facilitates the asymmetric division. This process depends on the affinity between PAR and microtubule-associated proteins such as Spindly, which contributes to a physical link for cortical PAR and the spindle. Notably, fusing a PAR-binding domain to end-binding protein 3, a plus-end tracking protein at the polar array microtubules, restores the asymmetric division of oocytes with Spindly knockdown. Thus, our work demonstrates a comprehensive mechanism for oocyte spindle positioning and asymmetric division. PMID- 29463903 TI - Feasibility of using urinary N7-(2-carbamoyl-2-hydroxyethyl) Guanine as a biomarker for acrylamide exposed workers. AB - Acrylamide (AA), a probable human carcinogen, is a widely-used industrial chemical but is also present in tobacco smoke and carbohydrate-rich foods processed at high temperatures. AA is metabolized to glycidamide (GA) to cause the formation of DNA adducts. N7-(2-carbamoyl-2-hydroxyethyl) guanine (N7-GAG), the most abundant DNA adduct induced by GA, was recently detected in urine of smokers and non-smokers. In this study, we assessed the variability of AA exposure and biomarkers of AA exposure in urine samples repeatedly collected from AA-exposed workers and explored the half-life of N7-GAG. A total of 8 AA-exposed workers and 36 non-exposed workers were recruited. Pre-shift and post-shift urine samples were collected from the exposed group in parallel with personal sampling for eight consecutive days and from the control group on day 1 of the study. Urinary N7-GAG and the mercapturic acids of AA and GA, namely N-acetyl-S-(2 carbamoylethyl)-L-cysteine (AAMA) and N-(R,S)-acetyl-S-(1-carbamoyl-2 hydroxyethyl)-L-cysteine (GAMA) were analyzed using on-line solid phase extraction-liquid chromatography-electrospray ionization/tandem mass spectrometry methods. We found that N7-GAG levels in urine were significantly higher in exposed workers than in controls and that N7-GAG level correlated positively with AAMA and GAMA levels. Results from this study showed that AAMA and GAMA possibly remain the more preferred biomarkers of AA exposure and that N7-GAG levels could be elevated by occupational exposures to AA and serve as a biomarker of AA induced genotoxicity for epidemiological studies.

The prevalence of NAFLD is 20-30% in North America, northern Europe, Australia, Japan, India and China. It is crucial that patients with NAFLD receive an assessment for their risk of advanced fibrosis, which increases the risk of hepatocellular carcinoma and other complications of cirrhosis. Risk stratification that is efficient, cost-effective, patient-centred and evidence-based is one of the most important issues facing clinicians who care for those with liver disease. Given patients' preference to avoid liver biopsy, noninvasive alternatives to assess liver fibrosis are in high demand. The most accurate noninvasive methods are based on liver elastography. Research on these techniques - which include vibration-controlled transient elastography (VCTE), magnetic resonance elastography (MRE), shear-wave elastography and acoustic radiation force impulse - has proliferated. Unfortunately, the literature has not kept pace with clinical practice. There is limited guidance for how clinicians should anticipate and manage the pitfalls of these tests. Furthermore, guidance is unavailable for clinicians regarding the optimal incorporation of VCTE, MRE or the emerging elastographic techniques into their clinical strategy, particularly for patients with NAFLD. In this Review, we summarize the available evidence, highlight gaps to address in further research and explore optimization of these techniques in clinical practice. PMID- 29463908 TI - Neural responses to cues paired with methamphetamine in healthy volunteers. AB - Drug cues, or conditioned responses to stimuli paired with drugs, are widely believed to promote drug use. The acquisition of these conditioned responses has been well characterized in laboratory animals: neutral stimuli paired with drugs elicit conditioned responses resembling the motivational and incentive properties of the drug itself. However, few studies have examined acquisition of conditioning, or the nature of the conditioned response, in humans. In this study, we used fMRI to examine neural responses to stimuli that had been paired with methamphetamine or placebo in healthy young adults. Participants first underwent four conditioning sessions in which visual-auditory stimuli were paired with either methamphetamine (20 mg, oral) or placebo. Then on a drug-free test day, the stimuli were presented during an fMRI scan to assess neural responses to the stimuli. We hypothesized that the stimuli would elicit drug-like brain activity, especially in regions related to reward. Instead, we found that the methamphetamine-paired stimuli, compared to placebo-paired stimuli, produced greater activation in regions related to visual and auditory processing, consistent with the drug's unconditioned effects on sensory processing. This is the first study to demonstrate conditioned neural responses to drug-paired stimuli after just two pairings of methamphetamine in healthy adults. The study also illustrates that conditioned responses may develop to unexpected components of the drug's effects. PMID- 29463909 TI - The effects of 5-hydroxytryptophan on attention and central serotonin neurochemistry in the rhesus macaque. AB - Psychiatric disorders, particularly depression and anxiety, are often associated with impaired serotonergic function. However, serotonergic interventions yield inconsistent effects on behavioral impairments. To better understand serotonin's role in these pathologies, we investigated the role of serotonin in a behavior frequently impaired in depression and anxiety, attention. In this study, we used a quantitative, repeated, within-subject, design to test how L-5 hydroxytryptophan (5-HTP), the immediate serotonin precursor, modulates central serotoninergic function and attention in macaques. We observed that intramuscular 5-HTP administration increased cisternal cerebrospinal fluid (CSF) 5-HTP and serotonin. In addition, individuals' baseline looking duration, during saline sessions, predicted the direction and magnitude in which 5-HTP modulated attention. We found that 5-HTP decreased looking duration in animals with high baseline attention, but increased looking duration in low baseline attention animals. Furthermore, individual differences in 5-HTP's effects were also reflected in how engaged individuals were in the task and how they allocated attention to salient facial features-the eyes and mouth-of stimulus animals. However, 5-HTP constricted pupil size in all animals, suggesting that the bi directional effects of 5-HTP cannot be explained by serotonin-mediated changes in autonomic arousal. Critically, high and low baseline attention animals exhibited different baseline CSF concentrations of 5-HTP and serotonin, an index of extracellular functionally active serotonin. Thus, our results suggest that baseline central serotonergic functioning may underlie and predict variation in serotonin's effects on cognitive operation. Our findings may help inform serotonin's role in psychopathology and help clinicians predict how serotonergic interventions will influence pathologies. PMID- 29463907 TI - Acid and the basis for cellular plasticity and reprogramming in gastric repair and cancer. AB - Subjected to countless daily injuries, the stomach still functions as a remarkably efficient digestive organ and microbial filter. In this Review, we follow the lead of the earliest gastroenterologists who were fascinated by the antiseptic and digestive powers of gastric secretions. We propose that it is easiest to understand how the stomach responds to injury by stressing the central role of the most important gastric secretion, acid. The stomach follows two basic patterns of adaptation. The superficial response is a pattern whereby the surface epithelial cells migrate and rapidly proliferate to repair erosions induced by acid or other irritants. The stomach can also adapt through a glandular response when the source of acid is lost or compromised (that is, the process of oxyntic atrophy). We primarily review the mechanisms governing the glandular response, which is characterized by a metaplastic change in cellular differentiation known as spasmolytic polypeptide-expressing metaplasia (SPEM). We propose that the stomach, like other organs, exhibits marked cellular plasticity: the glandular response involves reprogramming mature cells to serve as auxiliary stem cells that replace lost cells. Unfortunately, such plasticity might mean that the gastric epithelium undergoes cycles of differentiation and de-differentiation that increase the risk of accumulating cancer-predisposing mutations. PMID- 29463910 TI - Several behavioral traits relevant for alcoholism are controlled by gamma2 subunit containing GABAA receptors on dopamine neurons in mice. AB - The risk factors for developing alcohol addiction include impulsivity, high sensitivity to the rewarding action of ethanol, and low sensitivity to its sedative and intoxicating effects. Genetic variation in GABAA receptor subunits, including the gamma2 subunit (Gabrg2), affects the risk for developing alcoholism. Alcohol directly potentiates GABAA receptors and activates the mesolimbic dopamine system. Here, we deleted Gabrg2 selectively in dopamine cells of adult mice. The deletion resulted in elevated firing of dopamine neurons and made them less sensitive to drugs acting at GABAA receptors. At the behavioral level, the deletion increased exploratory behavior and augmented both correct and incorrect responding in the go/no-go task, a test often used to assay the response inhibition component of impulsivity. In addition, conditioned place preference to alcohol, but not to cocaine or morphine, was increased. Ethanol induced locomotor activation was enhanced in the mice lacking Gabrg2 on dopaminergic cells, whereas the sedative effect of alcohol was reduced. Finally, the alcohol drinking, but not the alcohol preference, at a high concentration was increased in the mutant mice. In summary, deletion of Gabrg2 on dopamine cells induced several behavioral traits associated with high risk of developing alcoholism. The findings suggest that mice lacking Gabrg2 on dopaminergic cells could be used as models for individuals at high risk for developing alcoholism and that GABAA receptors on dopamine cells are protective against the development of excessive alcohol drinking. PMID- 29463911 TI - Disruption of lipid-raft localized Galphas/tubulin complexes by antidepressants: a unique feature of HDAC6 inhibitors, SSRI and tricyclic compounds. AB - Current antidepressant therapies meet with variable therapeutic success and there is increasing interest in therapeutic approaches not based on monoamine signaling. Histone deacetylase 6 (HDAC6), which also deacetylates alpha-tubulin shows altered expression in mood disorders and HDAC6 knockout mice mimic traditional antidepressant treatments. Nonetheless, a mechanistic understanding for HDAC6 inhibitors in the treatment of depression remains elusive. Previously, we have shown that sustained treatment of rats or glioma cells with several antidepressants translocates Galphas from lipid rafts toward increased association with adenylyl cyclase (AC). Concomitant with this is a sustained increase in cAMP production. While Galphas modifies microtubule dynamics, tubulin also acts as an anchor for Galphas in lipid-rafts. Since HDAC-6 inhibitors potentiate alpha-tubulin acetylation, we hypothesize that acetylation of alpha tubulin disrupts tubulin-Galphas raft-anchoring, rendering Galphas free to activate AC. To test this, C6 Glioma (C6) cells were treated with the HDAC-6 inhibitor, tubastatin-A. Chronic treatment with tubastatin-A not only increased alpha-tubulin acetylation but also translocated Galphas from lipid-rafts, without changing total Galphas. Reciprocally, depletion of alpha-tubulin acetyl transferase-1 ablated this phenomenon. While escitalopram and imipramine also disrupt Galphas/tubulin complexes and translocate Galphas from rafts, they evoke no change in tubulin acetylation. Finally, two indicators of downstream cAMP signaling, cAMP response element binding protein phosphorylation (pCREB) and expression of brain-derived-neurotrophic-factor (BDNF) were both elevated by tubastatin-A. These findings suggest HDAC6 inhibitors show a cellular profile resembling traditional antidepressants, but have a distinct mode of action. They also reinforce the validity of antidepressant-induced Galphas translocation from lipid-rafts as a biosignature for antidepressant response that may be useful in the development of new antidepressant compounds. PMID- 29463912 TI - Preclinical evaluation of the kappa-opioid receptor antagonist CERC-501 as a candidate therapeutic for alcohol use disorders. AB - Prior work suggests a role of kappa-opioid signaling in the control of alcohol drinking, in particular when drinking is escalated due to alcohol-induced long term neuroadaptations. Here, we examined the small molecule selective kappa antagonist CERC-501 in rat models of alcohol-related behaviors, with the objective to evaluate its potential as a candidate therapeutic for alcohol use disorders. We first tested the effect of CERC-501 on acute alcohol withdrawal induced anxiety-like behavior. CERC-501 was then tested on basal as well as escalated alcohol self-administration induced by 20% alcohol intermittent access. Finally, we determined the effects of CERC-501 on relapse to alcohol seeking triggered by both stress and alcohol-associated cues. Control experiments were performed to confirm the specificity of CERC-501 effects on alcohol-related behaviors. CERC-501 reversed anxiety-like behavior induced by alcohol withdrawal. It did not affect basal alcohol self-administration but did dose-dependently suppress self-administration that had escalated following long-term intermittent access to alcohol. CERC-501 blocked relapse to alcohol seeking induced by stress, but not when relapse-like behavior was triggered by alcohol-associated cues. The effects of CERC-501 were observed in the absence of sedative side effects and were not due to effects on alcohol metabolism. Thus, in a broad battery of preclinical alcohol models, CERC-501 has an activity profile characteristic of anti-stress compounds. Combined with its demonstrated preclinical and clinical safety profile, these data support clinical development of CERC-501 for alcohol use disorders, in particular for patients with negatively reinforced, stress driven alcohol seeking and use. PMID- 29463913 TI - Impact of co-administration of oxycodone and smoked cannabis on analgesia and abuse liability. AB - Cannabinoids combined with opioids produce synergistic antinociceptive effects, decreasing the lowest effective antinociceptive opioid dose (i.e., opioid-sparing effects) in laboratory animals. Although pain patients report greater analgesia when cannabis is used with opioids, no placebo-controlled studies have assessed the direct effects of opioids combined with cannabis in humans or the impact of the combination on abuse liability. This double-blind, placebo-controlled, within subject study determined if cannabis enhances the analgesic effects of low dose oxycodone using a validated experimental model of pain and its effects on abuse liability. Healthy cannabis smokers (N = 18) were administered oxycodone (0, 2.5, and 5.0 mg, PO) with smoked cannabis (0.0, 5.6% Delta9 tetrahydrocannabinol [THC]) and analgesia was assessed using the Cold-Pressor Test (CPT). Participants immersed their hand in cold water (4 degrees C); times to report pain (pain threshold) and withdraw the hand from the water (pain tolerance) were recorded. Abuse-related effects were measured and effects of oxycodone on cannabis self administration were determined. Alone, 5.0 mg oxycodone increased pain threshold and tolerance (p <= 0.05). Although active cannabis and 2.5 mg oxycodone alone failed to elicit analgesia, combined they increased pain threshold and tolerance (p <= 0.05). Oxycodone did not increase subjective ratings associated with cannabis abuse, nor did it increase cannabis self-administration. However, the combination of 2.5 mg oxycodone and active cannabis produced small, yet significant, increases in oxycodone abuse liability (p <= 0.05). Cannabis enhances the analgesic effects of sub-threshold oxycodone, suggesting synergy, without increases in cannabis's abuse liability. These findings support future research into the therapeutic use of opioid-cannabinoid combinations for pain. PMID- 29463914 TI - Oxidation-stable amine-containing adsorbents for carbon dioxide capture. AB - Amine-containing solids have been investigated as promising adsorbents for CO2 capture, but the low oxidative stability of amines has been the biggest hurdle for their practical applications. Here, we developed an extra-stable adsorbent by combining two strategies. First, poly(ethyleneimine) (PEI) was functionalized with 1,2-epoxybutane, which generates tethered 2-hydroxybutyl groups. Second, chelators were pre-supported onto a silica support to poison p.p.m.-level metal impurities (Fe and Cu) that catalyse amine oxidation. The combination of these strategies led to remarkable synergy, and the resultant adsorbent showed a minor loss of CO2 working capacity (8.5%) even after 30 days aging in O2-containing flue gas at 110 degrees C. This corresponds to a ~50 times slower deactivation rate than a conventional PEI/silica, which shows a complete loss of CO2 uptake capacity after the same treatment. The unprecedentedly high oxidative stability may represent an important breakthrough for the commercial implementation of these adsorbents. PMID- 29463915 TI - Opportunistic random searcher versus intentional search image user. AB - We consider two types of optimal foragers: a random searcher and a search image user. A search image user can find its desired prey with higher and undesired prey with lower probability than a random searcher. Our model considers the density-dependent travelling time and the time duration of reproduction (oviposition). In the framework of optimal foraging theory for one predator-two prey systems, we find that there are ranges of prey densities in which the search image user has a higher net energy intake, and there are other ranges of prey densities in which the random searcher has higher net energy intake. The damsel bug Nabis pseudoferus Remane (Hemiptera: Nabidae) is a generalist predator rather than an omnivore. This species has a wide range of arthropod prey (predominantly insects and mites). Several aspects of the biology of this species have been studied, especially its cannibalistic behaviour, which is a quite important feature because N. pseudoferus is often used as a biological control agent against lepidopteran pests in greenhouse crops. Experimentally, we found that Nabis is a search image user in the above sense. PMID- 29463916 TI - Evaluating feasibility and accuracy of non-invasive tests for nonalcoholic fatty liver disease in severe and morbid obesity. AB - INTRODUCTION: In obese individuals, nonalcoholic fatty liver disease (NAFLD) is common but often goes undiagnosed, and therefore untreated. The presence of significant fibrosis is a key determinant of NAFLD progression, and liver steatosis has substantial cardiovascular implications. We aimed to determine the diagnostic accuracy of common noninvasive diagnostic tests for steatosis and fibrosis in the obese. METHODS: We recruited 182 severely and morbidly obese individuals undergoing bariatric surgery (age 44 +/- 12 years, body mass index 45.1 +/- 8.3 kg/m2). Medical history, blood tests and liver biopsy were taken on the day of surgery. Serum steatosis and fibrosis scores were calculated. In a subgroup of patients, transient elastography with controlled attenuation parameter (TE/CAP) (n = 82) and proton magnetic resonance spectroscopy (1H-MRS) (n = 49) were performed. RESULTS: 1H-MRS had excellent diagnostic accuracy for steatosis, with strong correlation to steatosis (r = 0.647, p < 0.001), good AUROC (0.852, p = 0.001), sensitivity (81.3%) and specificity (87.5%). However, due to low feasibility in this cohort (65.3% success), this was substantially decreased with intention-to-diagnose analysis (sensitivity 50.0%, specificity 60.9%). CAP had good feasibility (80.5%), and performed better in intention-to diagnose analysis (AUROC 0.688, sensitivity 84.8%, specificity 47.2%). Serum steatosis scores performed poorly, with comparable accuracy to ALT. For significant fibrosis, TE had the best accuracy (AUROC 0.903, p = 0.007), which remained reasonable after intention-to-diagnose analysis (sensitivity 100%, specificity 59.0%). A combination approach using CAP with ALT for steatosis and TE with Forn index for fibrosis yielded reasonable overall accuracy. CONCLUSIONS: 1H-MRS and TE/CAP had greatest accuracy for NAFLD-related steatosis and fibrosis. Failure rates in obesity significantly diminished diagnostic ability. Use of a combination of serum and imaging tests improved overall feasibility of assessment and diagnostic accuracy in obese individuals. PMID- 29463918 TI - Sex differences in the metabolic effects of diet-induced obesity vary by age of onset. AB - Sex differences in the effect of diet-induced obesity (DIO) have been reported in juvenile mice. However, thorough side by side comparisons of the effects of DIO in males and females at different ages of onset have yet to be examined. We hypothesized that aged females would lose their protection, relative to males, from the effects of DIO. We examined the effect of DIO on body weight and glucose tolerance in juvenile, young adult, and middle-aged male and female mice. Our data show DIO in juvenile mice causes a greater increase in body weight and greater impairment in glucose tolerance in males than females. However, if the diet is initiated in young adult mice, these sex differences are absent. Further, if the diet is initiated in middle-aged mice, the sex difference is reversed, and females gain more weight and have greater impairment in glucose tolerance than males. Our data show that sex differences in the effect of DIO vary by age of onset; thus highlighting the importance of both age and sex as biological variables in DIO research. PMID- 29463917 TI - Infant temperament and parent use of food to soothe predict change in weight-for length across infancy: early risk factors for childhood obesity. AB - OBJECTIVES: Greater weight gain in infancy is a risk factor for childhood obesity. The present study examined the interaction between infant temperament and parent use of food to soothe infant distress (FTS) as predictors of weight gain across the first 2 years of life. SUBJECTS/METHODS: A total of 160 mother infant dyads were recruited into a longitudinal study. Infant temperament was assessed by parents through a questionnaire (surgency, negativity) and by observer ratings (surgency, irritability) during a laboratory visit when infants were 6 months old. Parents also completed a 3-day infant cry diary when their children were 6 months of age to assess when they used food in response to infant cry/fuss bouts. Infant weight/length was measured in the lab at 6 and 18 months. Multiple regressions were run to test the moderating effect of FTS on weight gain. RESULTS: Significant interactions were revealed for both measures of surgency and parent FTS in predicting weight gain. Surgent infants whose parents had a greater tendency to use FTS had greater weight-for-length gain in 1 year than if their parents tended to use less FTS. The interaction between observer ratings of irritability and parent FTS was also significant but in an unexpected direction. CONCLUSIONS: The findings point to the role of temperament, specifically surgency, in weight gain during infancy, but only if their parents used FTS. Surgency may have evoked this feeding practice that increased their health risk. PMID- 29463919 TI - Sex-dimorphic acceleration of pericardial, subcutaneous, and plasma lipid increase in offspring of poorly nourished baboons. AB - Developmental programming by reduced maternal nutrition alters function in multiple offspring physiological systems, including lipid metabolism. We have shown that intrauterine growth restriction (IUGR) leads to offspring cardiovascular dysfunction with an accelerated aging phenotype in our nonhuman primate, baboon model. We hypothesized age-advanced pericardial fat and blood lipid changes. In pregnancy and lactation, pregnant baboons ate ad lib (control) or 70% ad lib diet (IUGR). We studied baboon offspring pericardial lipid deposition with magnetic resonance imaging at 5-6 years (human equivalent 20-24 years), skinfold thickness, and serum lipid profile at 8-9 years (human equivalent 32-36 years), comparing values with a normative life-course baboon cohort, 4-23 years. Increased pericardial fat deposition occurred in IUGR males but not females. Female but not male total cholesterol, low-density lipoprotein, and subcutaneous fat were increased with a trend of triglycerides increase. When comparing IUGR changes to values in normal older baboons, the increase in male apical pericardial fat was equivalent to advancing age by 6 years and the increase in female low-density lipoprotein to an increase of 3 years. We conclude that reduced maternal diet accelerates offspring lipid changes in a sex-dimorphic manner. The interaction between programming and accelerated lipogenesis warrants further investigation.

AB - Interest in protein disulfide bond formation has recently increased because of the prominent role of disulfide bonds in bacterial virulence and survival. The first discovered pathway that introduces disulfide bonds into cell envelope proteins consists of Escherichia coli enzymes DsbA and DsbB. Since its discovery, variations on the DsbAB pathway have been found in bacteria and archaea, probably reflecting specific requirements for survival in their ecological niches. One variation found amongst Actinobacteria and Cyanobacteria is the replacement of DsbB by a homologue of human vitamin K epoxide reductase. Many Gram-positive bacteria express enzymes involved in disulfide bond formation that are similar, but non-homologous, to DsbAB. While bacterial pathways promote disulfide bond formation in the bacterial cell envelope, some archaeal extremophiles express proteins with disulfide bonds both in the cytoplasm and in the extra-cytoplasmic space, possibly to stabilize proteins in the face of extreme conditions, such as growth at high temperatures. Here, we summarize the diversity of disulfide-bond catalysing systems across prokaryotic lineages, discuss examples for understanding the biological basis of such systems, and present perspectives on how such systems are enabling advances in biomedical engineering and drug development.

AB - The employment of functional near-infrared spectroscopy (fNIRS) as a method of brain imaging has increased over the last few years due to its portability, low cost and robustness to subject movement. Experiments with fNIRS are designed in the face of a limited number of sources and detectors (optodes) to be positioned on selected portion(s) of the scalp. The optodes locations represent an expectation of assessing cortical regions relevant to the experiment's hypothesis. However, this translation process remains a challenge for fNIRS experimental design. In the present study, we propose an approach that automatically decides the location of fNIRS optodes from a set of predefined positions with the aim of maximizing the anatomical specificity to brain regions of-interest. The implemented method is based on photon transport simulations on two head atlases. The results are compiled into the publicly available "fNIRS Optodes' Location Decider" (fOLD). This toolbox is a first-order approach to bring the achieved advancements of parcellation methods and meta-analyses from functional magnetic resonance imaging to more precisely guide the selection of optode positions for fNIRS experiments.

PMID- 29463932 TI - Cell-based Biological Pacemakers: Progress and Problems. AB - The number of permanent pacemaker implantations has been increasing due to the aging of populations worldwide and the increase in the numbers of patients with heart diseases. Commercially available mechanical pacemakers are very useful but still have some problems including short battery life, a risk of infection, the absence of physiological autonomic responsiveness, metal allergy, and electronic interference. A biological pacemaker may resolve these problems and regenerate the cardiac pacemaker. Cell-based therapy and gene therapy have been addressed with the goal of solving the challenges of biological pacemaker. However, the clinical application of a biological pacemaker has not yet been realized. Here we discuss the types of cells that can be used for a biological pacemaker and the problems that remain regarding the clinical applications of cell-based therapy. PMID- 29463933 TI - A Randomized Controlled Trial of Short-term Toe Resistance Training to Improve Toe Pinch Force in Patients with Type 2 Diabetes. AB - Resistance training is effective against type 2 diabetes (T2DM), but the effect of resistance training on toe pinch force (TPF) is unknown. Here we investigated the effect of short-term toe resistance training on TPF in patients with T2DM, in a prospective, parallel-group, single-blind, randomized controlled trial. Twelve patients with T2DM who were hospitalized to improve glycemic control were enrolled. The patients were randomly allocated to the intervention (n=6) and control (n=6) groups. The intervention group performed traditional aerobic exercise and 4 newly developed toe-resistance training exercises. The control group performed aerobic exercise only. After 2 weeks of the exercise intervention program, we evaluated anthropometric parameters, clinical parameters, motor function, and muscle parameters in each patient. After the exercise intervention program, the TPF and toe muscle quality, isometric knee extension force, and knee muscle quality were significantly higher in the intervention group compared to the control group. Two weeks of toe-resistance training significantly increased the TPF in the T2DM patients. Toe resistance training is thus recommended in clinical practice for patients with T2DM.

AB - In patients with poliomyelitis, degenerative arthritis of the hip may be encountered in the paralytic or normal contralateral limb because of leg length discrepancy, pelvic obliquity, or severe deformities of the affected hip. Although total hip arthroplasty (THA) is one of the most common orthopedic procedures, there are few reports of THA in adult patients with residual poliomyelitis. From March 2001 to January 2011, 5 patients with residual poliomyelitis (6 hips) underwent THA using uncemented implants at our hospital. We retrospectively evaluated the Japanese Orthopedic Association (JOA) hip rating score, complications, and radiographs. All five patients' follow-up information was available: 4.5 years minimum, 8.4 years average, range 4.5-15 years. Surgery was done at the same side of the paralytic limb in 2 hips and contralateral to the paralytic limb in four hips. All patients had pain relief and improvement in function; JOA hip rating score improved significantly from the mean of 45 preoperatively to 78 at the last follow-up (p=0.0313). There was no loosening or osteolysis in this series, and no cases of dislocation, infection or nerve palsy. These findings can contribute to decisions regarding treatment for arthritic hips in adults with residual poliomyelitis. PMID- 29463935 TI - A20 (TNFAIP3) Alterations in Primary Intestinal Diffuse Large B-cell Lymphoma. AB - The gastrointestinal (GI) tract is the most frequently involved site of extranodal non-Hodgkin lymphomas, and diffuse large B-cell lymphoma (DLBCL) is the most common subtype occurring in the GI tract. TNFAIP3 (A20) genetic alterations were reported to be involved in DLBCL's pathogenesis and a portion of GI-DLBCL cases harbor this alteration. However, the frequency and clinicopathological relations focusing on small and large intestinal DLBCL are unclear. Here, we examined A20 deletion and protein expression and analyzed the clinicopathological features of 52 cases of primary intestinal DLBCL. The most frequently involved site was the ileocecal region (75%), followed by small bowel (13.5%) and large intestine. Immunohistochemically, the ileocecal cases expressed BCL6 (p=0.027) and MUM1 (p=0.0001) significantly more frequently than the small intestinal cases. Six of 47 cases (13%) had A20 heterozygous deletion, whereas all 6 heterozygously deleted cases had detectable A20 protein expression. In summary, A20 abnormality was less prevalent among intestinal DLBCLs with some discordancy between gene deletion and protein expression. Although the A20 alteration status did not affect any clinicopathological characteristics in this series, further studies exploring alterations of A20 and other NF-kappaB components in primary intestinal DLBCL are needed. PMID- 29463936 TI - Relationship between Social Participation, Physical Activity and Psychological Distress in Apparently Healthy Elderly People: A Pilot Study. AB - Few studies examined the relationship between social participation, physical activity and psychological distress in elderly people. Here we examined these relationships in apparently healthy elderly people. After exclusion of subjects who dropped out or did not meet enrollment criteria, the data of 86 subjects (apparently healthy elderly embers at a college health club; 25 males, 61 females) from July 20 to September 10, 2016 were used. We evaluated each subject's psychological distress using the K6 questionnaire, social participation by a self-completed questionnaire, and physical activity level by a triaxial accelerometer (7 consecutive days). The K6 scores were significantly correlated with social participation in the total series and the women. The K6 scores of the subjects who had engaged in social participation (1.847+/-2.231) were significantly lower (better) than those of the subjects who had not (6.714+/ 5.014). Both exercise limitation and social participation were significant predictors of the K6 scores. Our findings indicate that psychological distress in apparently healthy elderly people is not associated with physical activity, but is associated with social participation. Our results demonstrate that in healthy elderly people, participating in a social activity can help improve psychological distress. PMID- 29463937 TI - Results of a Treat-and-Eextend Regimen of Intravitreal Ranibizumab Injection for Macular Edema due to Branch Retinal Vein Occlusion. AB - To investigate the effectiveness of a treat-and-extend regimen (TAE) of intravitreal ranibizumab injections (IVR) for macular edema (ME) due to branch retinal vein occlusion (BRVO). We retrospectively examined 35 eyes of 35 patients with ME due to BRVO who underwent TAE for 1 year. Patients whose treatment interval extended to 12 weeks were switched to a pro re nata regimen (PRN; TAE to PRN group), while TAE was continued for patients whose treatment interval was less than 12 weeks (continued TAE group). Changes in best-corrected visual acuity (BCVA), central retinal thickness (CRT), and predictive factors for inclusion in the TAE to PRN group were analyzed. BCVA and CRT both improved significantly at 1 year compared with baseline (p<0.001). Sixteen eyes (45.7%) were included in the TAE to PRN group, while 19 eyes (54.3%) were included in the continued TAE group. BCVA in the TAE to PRN group was significantly better than that in the continued TAE group at 1 year (p=0.047). BCVA at baseline and macular BRVO were significant predictive factors for inclusion in the TAE to PRN group. TAE was effective for improving BCVA and CRT. The TAE to PRN group showed significantly better prognosis. PMID- 29463938 TI - Transcatheter Arterial Chemoembolization to Reduce Size of Hepatocellular Carcinoma before Radiofrequency Ablation. AB - Transcatheter arterial chemoembolization (TACE) is often performed before radiofrequency ablation (RFA) for the treatment of early-stage hepatocellular carcinoma (HCC). TACE prior to RFA can expand the ablated area and reduce the tumor size, facilitating complete ablation. However, the factors correlated with size reduction remain uncertain. The aim of this study was to identify the factors associated with size reduction by TACE and develop a formula to predict the reduction rate. A total of 100 HCC patients treated with TACE followed by RFA at least 20 days later were enrolled. The tumor size was measured at the time of TACE and RFA, and correlations between the reduction rate and 13 clinical factors were examined. A formula to predict the reduction rate was built using the factors obtained by the analysis. Reduction in the tumor size was observed in 69 nodules, and the median reduction rate was 16.2%. A multivariate regression analysis revealed that a large tumor size (p< 0.01) and a long interval between the therapies (p= 0.01) were factors for a high tumor reduction rate, with tumor size more strongly related to the degree of reduction. A size reduction of more than 10% can be expected by waiting 20 days after TACE when the size of the tumor at TACE is over 25 mm in diameter. The tumor size. PMID- 29463939 TI - The Usefulness of Readout-Segmented Echo-Planar Imaging (RESOLVE) for Bio-phantom Imaging Using 3-Tesla Clinical MRI. AB - Readout-segmented echo-planar imaging (RESOLVE) is a multi-shot echo-planar imaging (EPI) modality with k-space segmented in the readout direction. We investigated whether RESOLVE decreases the distortion and artifact in the phase direction and increases the signal-to-noise ratio (SNR) in phantoms image taken with 3-tesla (3T) MRI versus conventional EPI. We used a physiological saline phantom and subtraction mapping and observed that RESOLVE's SNR was higher than EPI's. Using RESOLVE, the combination of a special-purpose coil and a large-loop coil had a higher SNR compared to using only a head/neck coil. RESOLVE's image distortioas less than EPI's. We used a 120 mM polyethylene glycol phantom to examine the phase direction artifact.vThe range where the artifact appeared in the apparent diffusion coefficient (ADC) image was shorter with RESOLVE compared to EPI. We used RESOLVE to take images of a Jurkat cell bio-phantom: the cell region ADC was 856*10-6mm2/sec and the surrounding physiological saline-region ADC was 2,951*10-6mm2/sec. The combination of RESOLVE and the 3T clinical MRI device reduced image distortion and improved SNR and the identification of accurate ADC values due to the phase direction artifact reduction. This combination is useful for obtaining accurate ADC values of bio-phantoms. PMID- 29463940 TI - Slow Fetal Heart Rate before Miscarriage in the Early First Trimester Predicts Fetal Aneuploidy in Women with Recurrent Pregnancy Loss. AB - Establishing whether miscarriages result from fetal aneuploidy or other factors is important for treating recurrent pregnancy loss. We examined the relationship between fetal heart rate (FHR) before miscarriage in the early first trimester and fetal karyotype, analyzing 223 pregnant women with recurrent pregnancy loss. Among the pregnancies, 110 resulted in live births regarded as normal karyotype (the Norm-group). The other 113 pregnancies ended in miscarriage, and we categorized them into groups based on fetal karyotype, determined by chorionic villus sampling: the Misc-NK (normal karyotype) group, n=35 euploid cases; the Misc-CA1 (chromosomal abnormality) group, n=18 cases of aneuploidy with trisomies 13/18/21, Turner's syndrome, or Klinefelter's syndrome; and the Misc-CA2 subgroup, n=60 cases of other aneuploidies excluding those in the Misc-CA1 group. We compared the groups' regression line slopes and intercepts for FHR by an analysis of covariance. The FHRs of the Norm, Misc-NK and Misc-CA1 groups increased from 36 to 49 days after fertilization, but did not significantly differ across these groups. The Misc-CA2 group's FHR did not increase and significantly differed from the other three groups (p<0.01). These results suggest that the absence of an increase in FHR in early pregnancy may indicate the presence of chromosomal abnormalities causing miscarriage. PMID- 29463941 TI - Differences in Risk Factors for Rotator Cuff Tears between Elderly Patients and Young Patients. AB - It has been unclear whether the risk factors for rotator cuff tears are the same at all ages or differ between young and older populations. In this study, we examined the risk factors for rotator cuff tears using classification and regression tree analysis as methods of nonlinear regression analysis. There were 65 patients in the rotator cuff tears group and 45 patients in the intact rotator cuff group. Classification and regression tree analysis was performed to predict rotator cuff tears. The target factor was rotator cuff tears; explanatory variables were age, sex, trauma, and critical shoulder angle>=35 degrees . In the results of classification and regression tree analysis, the tree was divided at age 64. For patients aged>=64, the tree was divided at trauma. For patients aged<64, the tree was divided at critical shoulder angle>=35 degrees . The odds ratio for critical shoulder angle>=35 degrees was significant for all ages (5.89), and for patients aged<64 (10.3) while trauma was only a significant factor for patients aged>=64 (5.13). Age, trauma, and critical shoulder angle>=35 degrees were related to rotator cuff tears in this study. However, these risk factors showed different trends according to age group, not a linear relationship. PMID- 29463942 TI - Spinal Extradural Arachnoid Cyst: Significance of Intrathecal Infusion after Fistula Closure. AB - The spinal extradural arachnoid cyst is a rare entity. Obtaining the correct diagnosis and detecting the fistula location are critical for providing effective treatment. A 41-year-old man had numbness in the soles of his feet for 2 years with accompanying gait disturbance, and a defecation disorder. Computed tomography myelography performed at another hospital revealed an epidural arachnoid cyst from Th11 to L2. He received a subarachnoid-cyst shunt at the rostral part of the cyst. However, his symptoms worsened and he was admitted to our hospital. Neuroradiological investigations revealed the correct location of the fistula at the level of Th12. We performed partial removal of the cyst wall with fistula closure via right hemilaminectomy of Th11 and 12. The complete closure of the fistula was confirmed by intrathecal infusion of artificial cerebrospinal fluid through the shunt tube. The shunt tube was removed with the sutures. The patient's symptoms improved, although numbness remained in his bilateral heels. There has been no recurrence in 15 months since the surgery. Fistula closure may work as a balanced therapeutic strategy for spinal extradural arachnoid cyst, and intrathecal cerebrospinal fluid infusion is useful for the confirmation of complete fistula closure. PMID- 29463943 TI - Tarsal Tunnel Syndrome Caused by a Schwannoma of the Posterior Tibial Nerve. AB - Schwannoma is the most common tumor of the peripheral nerve sheath. However, there have been few reports on schwannoma of the posterior tibial nerve causing tarsal tunnel syndrome. We report on a 60-year-old man with tarsal tunnel syndrome caused by a schwannoma of the posterior tibial nerve, which was first diagnosed as a ganglion cyst. After enucleation of this tumor, the patient was asymptomatic and had no related sequelae except for minor numbness in the plantar aspects of his digits. Although schwannoma of the posterior tibial nerve is rare, it should be considered even if a ganglion is clinically suspected. PMID- 29463944 TI - Laparoscopic Surgery for Small Bowel Obstruction due to Paracecal Hernia. AB - Internal hernia related to paracecal hernia is a rare disease and is difficult to confirm by preoperative diagnosis. We recently encountered a case of an 83-year old woman who had lower abdominal pain in her right quadrant. Based on physical findings and CT findings she was diagnosed as having small bowel obstruction by internal hernia around the cecum. She underwent emergency operation with laparoscopic surgery and was diagnosed with a paracecal hernia and treated laparoscopically. After we dissected the ventral wall of the hernia sac and enlarged the hernia orifice, we reduced the trapped small intestine into the abdominal space. We determined that the herniated portion of the small intestine was not necrotic and therefore did not resect it. Although paracecal hernia is a rare internal hernia, physicians should be aware of it as a differential diagnosis for small bowel obstruction because of its rapid progression to strangulation and necrosis. We highlight the importance of recognizing CT findings of paracecal internal hernia. Laparoscopy was effective both for making a definitive diagnosis and treating paracecal hernia with relatively little invasion.

AB - Traumatic eyeball luxation is a rare clinical condition with a dramatic presentation. Here, we describe a unique case of traumatic globe luxation and complete optic nerve transection caused by heavy object compression. A 45-year old male automobile mechanic was injured when a truck slipped from its supports, crushing his head and face. On arrival, his right eyeball was obviously displaced anteriorly and he had no light perception. Computed tomography revealed complex frontal bone and facial fractures with underlying brain contusion in addition to complete transection of the right optic nerve. The patient was successfully treated using a multidisciplinary approach. PMID- 29463946 TI - Extensive Bilateral Patellar Tendon Ossification in a Spinal Cord Injury Patient.

An 84-year-old Japanese man with a spinal cord injury caused by a burst fracture of the T12 vertebra presented with a bony hard prominence on the left knee, which was injured in a traffic accident when he was 77 years old. Radiography revealed extensive ossification of the bilateral patellar tendons. We review the English literature with a focus on the localization of bilateral heterotopic ossification of the knee in patients who had a central nervous system injury. PMID- 29463947 TI - Randomized Controlled Trial of Epidural versus Patient-controlled Intravenous Analgesia for Postoperative Pain Control after Laparoscopic Gastrectomy. AB - Although epidural analgesia (EDA) is considered standard postoperative analgesia for open gastrectomy, it has been unclear whether EDA has benefits in laparoscopic gastrectomy (LG) because postoperative pain after a laparoscopic procedure is significantly reduced. We are conducting a two-arm, single-center, prospective randomized non-inferiority trial to evaluate the postoperative pain relief of patient-controlled intravenous analgesia (PCIA) compared to EDA. A total of 132 patients undergoing LG will be randomized to EDA and PCIA groups (n=64 each) for postoperative pain control. The primary endpoint is postoperative pain at 24 h after surgery. This study will clarify the optimal pain management after LG. PMID- 29463948 TI - MicroRNA-155-5p Overexpression in Peripheral Blood Mononuclear Cells of Chronic Lymphocytic Leukemia Patients Is a Novel, Independent Molecular Biomarker of Poor Prognosis. AB - MicroRNA-155-5p (miR-155-5p) is a proinflammatory, oncogenic miRNA, involved in various physiological processes, including hematopoiesis, immunity, inflammation, and cell lineage differentiation. It regulates important transcription factors, such as E2F2, hypoxia-inducible factor 1 (HIF1), and FOXO3. Recently, the dysregulation of miR-155-5p expression has been linked to chronic lymphocytic leukemia (CLL) pathogenesis. In this research study, we investigated the potential diagnostic and prognostic value of miR-155-5p in CLL. To achieve our goal, we isolated total RNA from peripheral blood mononuclear cells (PBMCs) collected from 88 CLL patients and 36 nonleukemic blood donors and performed polyadenylation of total RNA and reverse transcription. Next, we quantified miR 155-5p levels using an in-house-developed real-time quantitative PCR method, before proceeding to extensive biostatistical analysis. Thus, it appears that miR 155-5p is significantly overexpressed in PBMCs of CLL patients and can distinguish them from nonleukemic population. Kaplan-Meier OS analysis and bootstrap univariate Cox regression showed that high miR-155-5p expression predicts inferior OS for CLL patients (p < 0.001). Interestingly, miR-155-5p overexpression retains its unfavorable prognostic role in CLL patients stratified according to established prognostic factors [CD38 expression and mutational status of the immunoglobulin heavy chain variable region (IGHV)]. Thus, miR-155 5p appears as a promising, independent molecular biomarker of unfavorable prognosis in CLL. PMID- 29463949 TI - Diagnostic Value of the lncRNA NEAT1 in Peripheral Blood Mononuclear Cells of Patients with Sepsis. AB - Background: This study aims to evaluate the diagnostic value of nuclear-enriched abundant transcript 1 (NEAT1) expression in peripheral blood mononuclear cells (PBMCs) for the early diagnosis of sepsis. Methods: A total of 59 patients with sepsis, 52 noninfectious SIRS patients, and 56 healthy controls were recruited fort this study. The levels of NEAT1 expression in PBMCs were measured using quantitative real-time polymerase chain reaction (qRT-PCR). Results: Compared with healthy controls, NEAT1 expression of PBMCs in sepsis and SIRS groups were significantly increased (3.76 +/- 0.71- and 1.64 +/- 0.43-fold, resp.) (P < 0.01), but NEAT1 levels are significantly lower in the SIRS group than in the sepsis group, and there was no statistical significant relevance between survivors and nonsurvivors in patients with sepsis. NEAT1 with an area under the curve (AUC) of 0.851 (95% CI: 0.812-0.935) indicated sensitivity (67.85%) and specificity (87.27%) for the diagnosis for sepsis, the positive predictive value (PPV) was 83.3%, and the negative predictive value (NPV) was 71.6%. The AUC for NEAT1 in the diagnosis of SIRS versus healthy controls was 0.755 (95% CI: 0.664 0.847), with 69.23% sensitivity and 70.91% specificity, the PPV was 72.3%, and the NPV was 72.49%. Conclusion: Measurement of NEAT1 expression in PBMCs could be considered as a good additive marker for the diagnosis of sepsis. PMID- 29463950 TI - Efficacy of a Computer-Assisted Cognitive Rehabilitation Intervention in Relapsing-Remitting Multiple Sclerosis Patients: A Multicenter Randomized Controlled Trial. AB - Cognitive impairment is frequently encountered in multiple sclerosis (MS) affecting between 40-65% of individuals, irrespective of disease duration and severity of physical disability. In the present multicenter randomized controlled trial, fifty-eight clinically stable RRMS patients with mild to moderate cognitive impairment and relatively low disability status were randomized to receive either computer-assisted (RehaCom) functional cognitive training with an emphasis on episodic memory, information processing speed/attention, and executive functions for 10 weeks (IG; n = 32) or standard clinical care (CG; n = 26). Outcome measures included a flexible comprehensive neuropsychological battery of tests sensitive to MS patient deficits and feedback regarding personal benefit gained from the intervention on four verbal questions. Only the IG group showed significant improvements in verbal and visuospatial episodic memory, processing speed/attention, and executive functioning from pre - to postassessment. Moreover, the improvement obtained on attention was retained over 6 months providing evidence on the long-term benefits of this intervention. Group by time interactions revealed significant improvements in composite cognitive domain scores in the IG relative to the demographically and clinically matched CG for verbal episodic memory, processing speed, verbal fluency, and attention. Treated patients rated the intervention positively and were more confident about their cognitive abilities following treatment. PMID- 29463951 TI - Targeted Delivery of the HLA-B*27-Binding Peptide into the Endoplasmic Reticulum Suppresses the IL-23/IL-17 Axis of Immune Cells in Spondylarthritis. AB - Ankylosing spondylitis (AS) is highly associated with the expression of human leukocyte antigen-B27 (HLA-B*27). HLA-B*27 heavy chain (B27-HC) has an intrinsic propensity to fold slowly, leading to the accumulation of the misfolded B27-HC in the endoplasmic reticulum (ER) and formation of the HLA-B*27 HC homodimer, (B27 HC)2, by a disulfide linkage at Cys-67. (B27-HC)2 displayed on the cell surface can act as a ligand of the killer-cell Ig-like receptor (KIR3DL2). (B27-HC)2 binds to KIR3DL2 of NK and Th17 cells and activates both cells, resulting in the activation of the IL-23/IL-17 axis to launch the inflammatory reaction in AS patients. However, activation of the IL-23/IL-17 axis originally derived from the HLA-B*27 misfolding in the ER needs to be characterized. In this study, we delivered two HLA-B*27-binding peptides, KRGILTLKY and SRYWAIRTR, into the ER by using a tat-derived peptide (GRKKRRQRRR)-His6-ubiquitin (THU) vehicle. Both peptides are derived from the human actin and nucleoprotein of influenza virus, respectively. Our results demonstrated that targeted delivery of both HLA-B*27 binding peptides into the ER can promote the HLA-B*27 folding, decrease the levels of (B27-HC)2, and suppress the activation of the IL-23/IL-17 axis in response to lipopolysaccharide. Our findings can provide a new therapeutic strategy in AS. PMID- 29463952 TI - Phenotypic and Functional Properties of Tumor-Infiltrating Regulatory T Cells. AB - Regulatory T (Treg) cells maintain immune homeostasis by suppressing excessive immune responses. Treg cells induce tolerance against self- and foreign antigens, thus preventing autoimmunity, allergy, graft rejection, and fetus rejection during pregnancy. However, Treg cells also infiltrate into tumors and inhibit antitumor immune responses, thus inhibiting anticancer therapy. Depleting whole Treg cell populations in the body to enhance anticancer treatments will produce deleterious autoimmune diseases. Therefore, understanding the precise nature of tumor-infiltrating Treg cells is essential for effectively targeting Treg cells in tumors. This review summarizes recent results relating to Treg cells in the tumor microenvironment, with particular emphasis on their accumulation, phenotypic, and functional properties, and targeting to enhance the efficacy of anticancer treatment. PMID- 29463953 TI - Autosomal dominant retinitis pigmentosa rhodopsin mutant Q344X drives specific alterations in chromatin complex gene transcription. AB - Purpose: Epigenetic and transcriptional mechanisms have been shown to contribute to long-lasting functional changes in adult neurons. The purpose of this study was to identify any such modifications in diseased retinal tissues from a mouse model of rhodopsin mutation-associated autosomal dominant retinitis pigmentosa (ADRP), Q344X, relative to age-matched wild-type (WT) controls. Methods: We performed RNA sequencing (RNA-seq) at poly(A) selected RNA to profile the transcriptional patterns in 3-week-old ADRP mouse model rhodopsin Q344X compared to WT controls. Differentially expressed genes were determined by DESeq2 using the Benjamini & Hochberg p value adjustment and an absolute log2 fold change cutoff. Quantitative western blots were conducted to evaluate protein expression levels of histone H3 phosphorylated at serine 10 and histone H4. qRT-PCR was performed to validate the expression patterns of differentially expressed genes. Results: We observed significant differential expression in 2151 genes in the retina of Q344X mice compared to WT controls, including downregulation in the potassium channel gene, Kcnv2, and differential expression of histone genes, including the H1 family histone member, H1foo; the H3 histone family 3B, H3f3b; and the histone deacetylase 9, Hdac9. Quantitative western blots revealed statistically significant decreased protein expression of both histone H3 phosphorylated at serine 10 and histone H4 in 3-week-old Q344X retinas. Furthermore, qRT-PCR performed on select differentially expressed genes based on our RNA-seq results revealed matched expression patterns of up or downregulation. Conclusions: These findings provide evidence that transcriptomic alterations occur in the ADRP mouse model rhodopsin Q344X retina and that these processes may contribute to the dysfunction and neurodegeneration seen in this animal model. PMID- 29463954 TI - Association of plasma osteopontin with diabetic retinopathy in Asians with type 2 diabetes. AB - Purpose: Osteopontin (OPN) is a proinflammatory cytokine with diverse functions. Increased levels of OPN in vitreous fluid have been reported in patients with diabetic retinopathy (DR); however, studies on circulating OPN levels in DR are limited. We aim to examine the association of plasma OPN levels with the presence and severity of DR in a multiethnic cohort with type 2 diabetes mellitus (type 2 diabetes) in Singapore. Methods: Plasma levels of OPN were measured using enzyme linked immunosorbent assay. Digital color fundus photographs were assessed for DR. DR severity was categorized into non-proliferative DR (NPDR) and proliferative DR (PDR). Gradable fundus photographs and OPN measurements for 443 patients were used for analysis. A logistic regression model was used to evaluate the association of OPN with DR. Results: DR was diagnosed in 174 (39.3%) patients, including 132 (75.9%) with NPDR and 42 (24.1%) with PDR. The median of OPN was higher in the patients with DR (64.7 [49.7-89.5] ng/ml) than in the patients without DR (51.7 [38.9-66.9] ng/ml; p<0.001). After adjustment for clinical and biochemical factors, a 1-unit increase in nature logarithm (ln) transformed OPN was associated with the presence of DR (2.770 [1.599-3.800], p<0.001). The area under the curve (AUC) increased statistically significantly after the addition of OPN (0.805[0.763-0.846] versus 0.825 [0.785-0.865], p=0.011). In the severity analyses, the median of OPN was statistically significantly higher in the patients with PDR (76.8 [55.0-103.6] ng/ml) than in the patients with NPDR (61.7 [47.7-87.3] ng/ml; p=0.017). After adjustment, the 1 unit increase in lnOPN remained associated with NPDR (2.673 [1.519-4.704], p=0.001) and PDR (3.389 [1.254-9.226], p=0.017), respectively (p-trend=0.001). Conclusions: Plasma OPN levels were associated with the presence and severity of DR in patients with type 2 diabetes, suggesting OPN may be useful as a potential biomarker for DR. PMID- 29463956 TI - Low-Dimensional Motor Control Representations in Throwing Motions. AB - In this study, we identified a low-dimensional representation of control mechanisms in throwing motions from a variety of subjects and target distances. The control representation was identified at the kinematic level in task and joint spaces, respectively, and at the muscle activation level using the theory of muscle synergies. Representative features of throwing motions in all of these spaces were chosen to be investigated. Features were extracted using factorization and clustering techniques from the muscle data of unexperienced subjects (with different morphologies and physical conditions) during a series of throwing tasks. Two synergy extraction methods were tested to assess their consistency. For the task features, the degrees of freedom (DoF), and the muscles under study, the results can be summarized as (1) a control representation across subjects consisting of only two synergies at the activation level and of representative features in the task and joint spaces, (2) a reduction of control redundancy (since the number of synergies are less than the number of actions to be controlled), (3) links between the synergies triggering intensity and the throwing distance, and finally (4) consistency of the extraction methods. Such results are useful to better represent mechanisms hidden behind such dynamical motions and could offer a promising control representation for synthesizing motions with muscle-driven characters. PMID- 29463955 TI - Optic nerve regeneration in the mouse is a complex trait modulated by genetic background. AB - Purpose: The present study is designed to identify the influences of genetic background on optic nerve regeneration using the two parental strains (C57BL/6J and DBA/2J) and seven BXD recombinant inbred mouse strains. Methods: To study regeneration in the optic nerve, Pten was knocked down in the retinal ganglion cells using adenoassociated virus (AAV) delivery of shRNA, and a mild inflammatory response was induced with an intravitreal injection of zymosan with CPT-cAMP. The axons of the retinal ganglion cells were damaged by optic nerve crush (ONC). Following a 12-day survival period, regenerating axons were labeled by cholera toxin B, and 2 days later, the regenerating axons within the optic nerve were examined. The number of axons at 0.5 mm and 1 mm from the crush site were counted. In addition, we measured the distance that five axons had grown down the nerve and the longest distance a single axon reached. Results: The analysis revealed a considerable amount of differential axonal regeneration across the seven BXD strains and the parental strains. There was a statistically significant difference (p=0.014 Mann-Whitney U test) in the regenerative capacity in the number of axons reaching 0.5 mm from a low of 236.1+/-24.4 axons in the BXD102 mice to a high of 759.8+/-79.2 axons in the BXD29 mice. There were also statistically significant differences (p=0.014 Mann-Whitney U test) in the distance axons traveled. Looking at a minimum of five axons, the shortest distance was 787.2+/-46.5 um in the BXD102 mice, and the maximum distance was 2025.5+/-223.3 um in the BXD29 mice. Conclusions: Differences in genetic background can have a profound effect on axonal regeneration causing a threefold increase in the number of regenerating axons at 0.5 mm from the crush site and a 2.5-fold increase in the distance traveled by at least five axons in the damaged optic nerve.

During the last 30 years more than a 3-fold increase has been observed in Poland due to environmental and genetic factors. Almost all colorectal malignancies are related to the formation and malignant transformation of colorectal dysplasia and adenoma. Efforts aiming to decrease the number of colorectal cancer deaths are focused on the disease early detection. Genetic diagnosis for hereditary syndromes predisposing to colorectal cancer has been developed and is a part of the routine treatment. Most cancers are sporadic. They often develop from polyps in the colon. In addition to the genetic events described in the 1990s, showing the adenoma transformation into carcinoma that has been a prime example of malignant transformation for a long time, there are also other possibilities of neoplastic transformation. The recognition of colorectal cancer risk factors make sense as their nature is lifestyle- and diet related. In this review paper those risk factors are presented and the prevention of colorectal cancer is discussed taking into account genetic factors.

AB - Aim and background: IGRT based on bone matching may produce a large target positioning error in terms of the reproducibility of expiration breath-holding on SBRT for liver cancer. We evaluated the intrafractional and interfractional errors using the diaphragm position at the end of expiration by utilising Abches and analysed the factor of the interfractional error. Materials and methods: Intrafractional and interfractional errors were measured using a couple of frontal kV images, planning computed tomography (pCT) and daily cone-beam computed tomography (CBCT). Moreover, max-min diaphragm position within daily CBCT image sets with respect to pCT and the maximum value of diaphragm position difference between CBCT and pCT were calculated. Results: The mean +/- SD (standard deviation) of the intra-fraction diaphragm position variation in the frontal kV images was 1.0 +/- 0.7 mm in the C-C direction. The inter-fractional diaphragm changes were 0.4 +/- 4.6 mm in the C-C direction, 1.4 +/- 2.2 mm in the A-P direction, and -0.6 +/- 1.8 mm in the L-R direction. There were no significant differences between the maximum value of the max-min diaphragm position within daily CBCT image sets with respect to pCT and the maximum value of diaphragm position difference between CBCT and pCT. Conclusions: Residual intrafractional variability of diaphragm position is minimal, but large interfractional diaphragm changes were observed. There was a small effect in the patient condition difference between pCT and CBCT. The impact of the difference in daily breath-holds on the interfractional diaphragm position was large or the difference in daily breath-holding heavily influenced the interfractional diaphragm change.

PMID- 29463961 TI - Comparison of Chiropractic Treatment Outcomes Depending on the Language Region in Switzerland: A Prospective Outcomes Study. AB - Objectives: Switzerland has optimal conditions for research of language-based cultural influences on low back pain (LBP). The aim of this study was to compare LBP treatment outcomes after chiropractic care between patients from the German- and French-speaking regions of Switzerland. Methods: Baseline Numeric Rating Scale for pain (NRS), demographic, and Oswestry Disability Index (ODI) data were collected from patients presenting to 51 Swiss-German and 12 Swiss-French chiropractors. Prospective outcome data included the proportion reporting clinically relevant improvement on the Patient Global Impression of Change scale and the NRS change scores collected at 1 week; 1, 3, and 6 months; and 1 year. ODI change scores were collected until 3 months. The proportion improved between the 2 groups was compared using the chi2 test. NRS and ODI change scores were compared using the unpaired t test. Results: At baseline, only patient age comparing 853 Swiss-German and 215 Swiss-French patients revealed a significant difference. The Patient Global Impression of Change, NRS, and ODI had no significant differences between both patient groups up to 6 months. Between 6 months and 1 year the proportion reporting improvement continued to increase to 83.5% for German-speaking Swiss but reduced to 73.1% for French-speaking Swiss (P = .01). The NRS change scores were also higher for German speaking Swiss at 1 year compared with Swiss-French citizens (P = .01). Conclusion: Treatment outcome data for LBP are comparable in the German and French parts of Switzerland until the 1-year time point, when people located in the French-speaking regions are more likely to have an increase in pain levels. PMID- 29463960 TI - Comparison of 68Ga-DOTA-Siglec-9 and 18F-Fluorodeoxyribose-Siglec-9: Inflammation Imaging and Radiation Dosimetry. AB - Sialic acid-binding immunoglobulin-like lectin 9 (Siglec-9) is a ligand of inflammation-inducible vascular adhesion protein-1 (VAP-1). We compared 68Ga-DOTA and 18F-fluorodeoxyribose- (FDR-) labeled Siglec-9 motif peptides for PET imaging of inflammation. Methods. Firstly, we examined 68Ga-DOTA-Siglec-9 and 18F FDR-Siglec-9 in rats with skin/muscle inflammation. We then studied 18F-FDR Siglec-9 for the detection of inflamed atherosclerotic plaques in mice and compared it with previous 68Ga-DOTA-Siglec-9 results. Lastly, we estimated human radiation dosimetry from the rat data. Results. In rats, 68Ga-DOTA-Siglec-9 (SUV, 0.88 +/- 0.087) and 18F-FDR-Siglec-9 (SUV, 0.77 +/- 0.22) showed comparable (P = 0.29) imaging of inflammation. In atherosclerotic mice, 18F-FDR-Siglec-9 detected inflamed plaques with a target-to-background ratio (1.6 +/- 0.078) similar to previously tested 68Ga-DOTA-Siglec-9 (P = 0.35). Human effective dose estimates for 68Ga-DOTA-Siglec-9 and 18F-FDR-Siglec-9 were 0.024 and 0.022 mSv/MBq, respectively. Conclusion. Both tracers are suitable for PET imaging of inflammation. The easier production and lower cost of 68Ga-DOTA-Siglec-9 present advantages over 18F-FDR-Siglec-9, indicating it as a primary choice for clinical studies. PMID- 29463962 TI - A Survey of the Public Perception of Chiropractic After Exposure to Chiropractic Public Place Marketing Events in New Zealand. AB - Objective: The purpose of this study was to assess public perception of chiropractic public place marketing events. Method: A chiropractic public place marketing program was held at 3 events (a community sports event, an exposition, and a university campus market day) over a 5-month period in Auckland, New Zealand, between 2008 and 2009. Participants were interviewed by chiropractic students. Interview questions were standardized and sought to find out participants' perception of chiropractic and whether it was influenced in a positive or negative manner after their exposure to the marketing program. Results: Three hundred forty-five interviews were completed during 3 events. The minority of participants (15.9%) had a negative view of chiropractic, 29.2% were neutral, and 54.9% had a positive view of chiropractic. Of the responses of those surveyed, 54% did not change their opinion of chiropractic, 44.3% were more positive, and 1.7% were more negative. Conclusions: This study found that direct or indirect exposure to chiropractic public place marketing events may possibly influence the public perception of chiropractic. Because of the limited sample, these findings cannot be extrapolated to other regions or populations. Further studies are needed to test these findings in other world regions and in more controlled environments. PMID- 29463963 TI - Joint Manipulation: Toward a General Theory of High-Velocity, Low-Amplitude Thrust Techniques. AB - Objective: The objective of this study was to describe the initial stage of a generalized theory of high-velocity, low-amplitude thrust (HVLAT) techniques for joint manipulation. Methods: This study examined the movements described by authors from the fields of osteopathy, chiropractic, and physical therapy to produce joint cavitation in both the metacarpophalangeal (MCP) joint and the cervical spine apophysial joint. This study qualitatively compared the kinetics, the similarities, and the differences between MCP cavitation and cervical facet joint cavitation. A qualitative vector analysis of forces and movements was undertaken by constructing computer-generated, simplified graphical models of the MCP joint and a typical cervical apophysial joint and imposing the motions dictated by the clinical technique. Results: Comparing the path to cavitation of 2 modes of HVLAT for the MCP joint, namely, distraction and hyperflexion, it was found that the hyperflexion method requires an axis of rotation, the hinge axis, which is also required for cervical HVLAT. These results show that there is an analogue of cervical HVLAT in one of the MCP joint HVLATs. Conclusions: The study demonstrated that in a theoretical model, the path to joint cavitation is the same for asymmetric separation of the joint surfaces in the cervical spine and the MCP joints. PMID- 29463964 TI - Culturally Sensitive Chiropractic Care of the Transgender Community: A Narrative Review of the Literature. AB - Objectives: Transgender individuals commonly experience barriers to quality health care and may suffer from unique musculoskeletal complaints. Although these needs are often inadequately addressed within the health care system, they could be attended to by the chiropractic community. This narrative review describes best practices for delivering culturally sensitive care to transgender patients within the context of chiropractic offices. Methods: A literature search generated peer-reviewed material on culturally competent care of the transgender community. Google Scholar and trans-health RSS feeds on social media were also searched to find relevant gray literature. Information pertinent to a chiropractic practice was identified and summarized. Results: Contemporary definitions of transgender, gender identity, and sexual orientation provide a framework for culturally sensitive language and clinic culture. Small changes in record keeping and office procedures can contribute to a more inclusive environment for transgender patients and improve a chiropractor's ability to collect important health history information. Special considerations during a musculoskeletal examination may be necessary to properly account for medical and nonmedical practices transgender patients may use to express their gender. Chiropractors should be aware of health care and social and advocacy resources for transgender individuals and recommend them to patients who may need additional support. Conclusions: Small yet intentional modifications within the health care encounter can enable chiropractors to improve the health and well being of transgender individuals and communities. PMID- 29463965 TI - A Literature Review of Electronic Health Records in Chiropractic Practice: Common Challenges and Solutions. AB - Objective: The purpose of this study was to review the literature on current challenges and propose solutions for the optimal utilization of the electronic health records (EHRs) in chiropractic practice. Methods: A search was performed in the PubMed, Index of Chiropractic Literature, and Current Index to Nursing and Allied Health Literature databases from November 2005 to February 2015. A combination of the following key words was used: electronic health records, electronic medical records, implementation, documentation, benefits, and challenges. Articles were categorized into common problems and solutions. These were filtered by application to chiropractic or educational institutions. Results: The search resulted in 45 papers, which included case reports of EHR implementation, governmental insurance reports, commentaries, controlled studies, narrative reviews of past experiences with conversion from paper systems, and the implementation of EHRs in small offices and chiropractic offices. Minimal literature was found that directly related to chiropractic EHRs. Improper utilization, incorrect use of the software, faulty implementation, workflow burdens, financial considerations, and insufficient training were found to negatively affect the quality of the record. Conclusions: Documentation errors are often innate in the EHR software. Improper utilization, insufficient training, or difficulty in integration of the EHR into the clinical office setting results in poor implementation of the electronic version of the clinical record. Solutions that may decrease documentation errors include EHR training, continued financial incentives, and appropriate implementation process and utilization of available software features.

PMID- 29463969 TI - Sexual Dysfunction in Interstitial Cystitis. AB - Background/Aims: Interstitial cystitis (IC)/bladder pain syndrome (BPS) is a debilitating disease characterized with urgency, frequency, and pelvic pain affecting especially women. Sexual dysfunction in female patients with IC/BPS consists of dyspareunia, altered sexual desire and orgasm frequency and insufficient lubrication is reported to negatively affect the patient's quality of life. In the present study, we aimed to determine the association between IC/BPS and sexual dysfunction and improvement in sexual dysfunction related to given treatments. Methods: A PubMed/Medline and EMBASE search was conducted using keywords: "interstitial cystitis", "sexual dysfunction", and "bladder pain syndrome". Conclusion: Several studies have been conducted to determine the relation between IC/BPS and sexual dysfunction. And also limited studies focusing on IC/BPS specific treatments reported significant improvements in sexual function after either oral or intravesical treatment. However, given the used different questionnaires, study protocols, patient characteristics, previous treatments and follow-up period, it is not possible to make a head-to-head comparison of the treatment effects on sexual function. Further, randomized controlled studies are needed to confirm these results and make a comparison between effects of various treatment modalities on sexual functioning in IC/BPS. PMID- 29463970 TI - The Effect of Transdermal Testosterone Administration on Lower Urinary Tract Symptoms and Erectile Dysfunction: A Prospective, Randomized, Placebo-Controlled Trial. AB - Objective: This study aimed to evaluate the effects of transdermal testosterone administration on lower urinary tract symptoms (LUTS) and erectile dysfunction (ED). Materials and Method: Sixty-two male patients with Ageing Male Symptom Questionnaire (AMS-Q) scores over 27 and a total serum testosterone level below 350 ng/dl (12.1 nmol/l) who presented to our urology clinic with complaints of LUTS and ED, were enrolled in this study. Uroflowmetry and the International Prostate Symptom Scale were used to evaluate the severity of LUTS. The International Index of Erectile Function was used to detect the severity of ED. In addition, the AMS-Q was used to quantify the severity of hypogonadism. We randomly divided patients into 2 groups. Thirty-one patients in the first group had transdermal testosterone administered at a daily dose of 50 mg (a sachet of 5 g) on the skin for 3 months. In the second group, 31 patients had a placebo administered for 3 months. The scales were recompleted based on interviews and uroflowmetry was repeated during checks of the patients performed in the first and third months. Results: We detected a decrease in AMS-Q scores and an increase in maximum uroflow rate values and the International Index of Erectile Function scores in the first group compared with the placebo group. Although a decrease was detected in post-treatment International Prostate Symptom Scale scores in the first group, it was not regarded as statistically significant. Conclusion: This study revealed that testosterone replacement therapy is effective in improving LUTS and ED symptoms. PMID- 29463971 TI - Physician Perceptions of Patient Health: A Comparative Analysis between Urologist and Hospitalist Perceptions of Need for Inpatient Hospitalist Comanagement Following Radical Cystectomy. AB - Background/Aims: The morbidity of radical cystectomy remains high. A multidisciplinary approach utilizing hospitalist comanagement may improve outcomes. It is unclear what factors should be considered to determine which patients might benefit from this approach. We sought to determine if there are differences between the perceived need for co-management between urologists and hospitalists. Preoperative variables were analyzed to determine which factors might be associated with need for comanagement. Methods: A case-based survey was emailed to urologists and hospitalists at 3 academic institutions to investigate perceptions regarding need for inpatient medical comanagement of fictitious patients following cystectomy. Decisions were rated based on patient comorbidities, age, race, sex, cancer stage, neoadjuvant therapy, alcohol intake, performance status, and English literacy. A Wilcoxon rank sum test assessed each question for differences. A Mantel-Haenszel chi-square test was used to assess whether the proportion of respondents who advocated for comanagement increased as Charlson comorbidity score increased. Results: The most significant determinant of need for postoperative comanagement was patients' comorbidities. Urologists and hospitalists did not differ significantly in beliefs regarding need for comanagement. Conclusion: The most important determining factor for comanagement was presence of comorbidities. Further studies are needed to evaluate the impact of this multidisciplinary approach. PMID- 29463972 TI - Quality of Life Following Prostatectomy as a Function of Surgery Type and Degree of Nerve Sparing. AB - Objectives: To compare robotic-assisted laparoscopic prostatectomy with conventional retropubic radical prostatectomy in maintaining pre-surgery levels of urinary and sexual functioning and to evaluate the efficacy of nerve sparing in prostatectomies in protecting urinary functioning. Material and Methods: Patients (n = 385) receiving both surgical procedures were surveyed prior to surgery. Multiple measures, including the Expanded Prostate Cancer Index Composite, the Sexual Health Inventory for Men, and the International Prostate Symptom Score, assessed sexual and urinary function at an average of 12 months post-surgery. Results: Across multiple measures, while controlling for pre surgical sexual functioning, robotic-assisted surgery did not offer an advantage in maintaining sexual or urinary function an average of a year following the prostatectomy. Bilateral nerve sparing offered a strong and reliable advantage in the maintenance of sexual function, but not so regarding urinary function. Conclusion: While robotic-assisted prostatectomies may offer a number of medical advantages over open procedures, we found no significant effect on important quality of life outcomes associated with the technique. PMID- 29463973 TI - Urological Management of Extramural Malignant Ureteric Obstruction: A Survey of Irish Urologists. AB - Introduction: The absence of guidelines in the management of extramural malignant ureteric obstruction leads to confusion in decision making and in the interaction between urology and other clinical disciplines. In this study, we surveyed consultant urologists with the goal of achieving a better consensus on optimal management options. Methods: A multiple choice survey was sent via the online survey tool "SurveyMonkey" to all consultant urologists practicing in the Republic of Ireland. Results: There was a response rate of 57.5% (n = 23). Twenty two (96%) consultants consider the use of percutaneous nephrostomy with placement of antegrade ureteric stent but only 22% (n = 5) would consider using a metallic stent. Eleven (48%) respondents favor retrograde stenting in the first instance with an equal proportion choosing an antegrade method. Nine (39%) consultants perform the initial stent change at 4-6 months, 8 (35%) at 2-4 months, and 1 at < 2 months and 6-10 months respectively. Total 59% (n = 13) of respondents felt that the duration of expected patient survival influenced their decision and agreement to stent with 42% (n = 8) saying this survival would need to be > 6 months and 82% (n = 18) were generally happy with the level of ongoing communication between urology and the primary service managing the patient. Conclusion: There is a lack of consensus regarding the management of this challenging problem, particularly with regard to timing of first stent change and whether to initially use an antegrade or retrograde approach. This reflects the heterogeneous patient cohort and the important factors of life expectancy and patient co-morbidities. PMID- 29463974 TI - "Researching the Research" in Prostate Cancer: A Comparative Bibliometric Analysis of the Top 100 Cited Articles in the Field of Prostate Cancer. AB - Background: To perform the first comparative bibliometric analysis of the "Top 100 (T100) cited articles in prostate cancer (PCa)". Materials and Methods: A comprehensive search using the Web of Science Database (v 5.21) covering the Web of ScienceTM Core Collection, BIOSIS Previews, Central Contents Connect, KCI Korean Journal Database, MEDLINE, SciELO Index (February 2016) was performed, for all articles relevant to PCa. Results: The T100 were cited 582 to 3,387 times, and were published from 1966 to 2012. The top 3 subcategories associated with PCa included: genetics/biomarkers (n = 34), management (n = 25), and physiology (n = 11). T100 contributions from USA (n = 86), were most prominent. If the regional citation was corrected for percentage on research (citation record/percentage gross domestic product on research) a variation in the ranking was noted. Conclusion: The first bibliometric analysis in the field of PCa is presented. Regions that predominate the T100, include the United States and Europe. Articles published in higher impact factor journals, in English medium and content related to PCa research associated with genetics/bio-markers have the highest citation potential. PMID- 29463975 TI - Retropubic, Laparoscopic, and Robot-Assisted Radical Prostatectomy: A Comparative Analysis of the Surgical Outcomes in a Single Regional Center. AB - Background: To compare the surgical outcomes of radical prostatectomy (RP) performed via 3 different approaches: retropubic (RRP), laparoscopic-assisted (LRP), and robot-assisted (RARP), in a single non-academic regional center by a single surgeon. Materials and Methods: The data of patients undergoing RP from 2005 to 2014 were reviewed. The standard approach changed through the years: RRP (n = 380, years 2005 to 2008), LRP (n = 240, years 2009 to 2011), and RARP (n = 262, years 2012 to 2014). Our analysis included the last consecutive 100 RP for each surgical technique by a single surgeon. A logistic regression model adjusted for pre-and postoperative variables was done to evaluate whether transfusion, conversion, and post-operative complication rates were influenced by the approach. Results: RARP was associated with significantly lower blood loss (400 vs. 600 and 600 ml, respectively), transfusion (6 vs. 21 and 21%, respectively), and shorter hospital stay (6 vs. 7 and 8 days, respectively), compared to LRP and RRP, and a lower conversion rate (1 vs. 12%) compared to LRP. Multivariate analysis adjusted for confounders confirmed that the risk of transfusion and conversion was significantly lower in the RARP group compared to the LRP and RRP groups. The RARP group was also associated with a significantly lower risk of complications compared to the RRP group and with a trend in favor of the RARP group compared to the LRP group. The 1-year continence rate was significantly higher in the RARP group compared to the RRP and LRP groups (80 vs. 72 and 68%, respectively). Conclusion: The surgical approach affected the operative outcomes in a regional setting. The advantages of RARP over RRP (complications, transfusion, conversion, hospital stay, 1-year continence) were over LRP as well, with the only exception being complications. PMID- 29463976 TI - A Simple and Novel Method to Attain Retrograde Ureteral Access after Previous Cohen Cross-Trigonal Ureteral Reimplantation. AB - Objective: To describe a simple, novel method to achieve ureteric access in the Cohen crossed reimplanted ureter, which will allow retrograde working access via the conventional transurethral method. Materials and Methods: Under cystoscopic vision, suprapubic needle puncture was performed. The needle was directed (bevel facing) towards the desired ureteric orifice (UO). A guidewire (with a floppy tip) was then inserted into the suprapubic needle passing into the bladder, and then easily passed into the crossed-reimplanted UO. The distal end of the guidewire was then removed through the urethra with cystoscopic grasping forceps. The straightened ureter then easily facilitated ureteroscopy access, retrograde pyelogram studies, and JJ stent insertion in a conventional transurethral method. Results: The UO and ureter were aligned in a more conventional orthotopic course, to allow for conventional transurethral working access. Conclusion: A novel method to access the Cohen crossed reimplanted ureter was described. All previously published methods of accessing the crossed ureter were critically appraised. PMID- 29463977 TI - A Ureteral Inguinoscrotal Hernia from a Pelvic Kidney. AB - A 74-year-old male patient with prostate cancer under remission was admitted with left inguinoscrotal swelling. He underwent scrotal ultrasound demonstrating a giant in-guinoscrotal hernia. Contrast-enhanced computerized tomography of the abdomen and pelvis demonstrated a left pelvic kidney associated with severe hydroureteronephrosis secondary to a ureteral inguinoscrotal hernia. Upon exploration with left inguinal incision, a paraperitoneal ureteral in guinoscrotal hernia and a hypertrophic left spermatic cord were observed. The elongated and tortuous left ureter, being pulled down to the scrotum by the hernia, was released from the herniating tissues fullfilling left hemiscrotum. The ureter was tapered followed by ureteroureterostomy. The accompanying left spermatic cord was excessively elongated and curled, necessitating cordectomy. The hernia was repaired with prolene mesh after removal of herniating peritoneal tissue. This is a rare case of a paraperitoneal ureteral inguinoscrotal hernia of the left pelvic kidney. PMID- 29463978 TI - Genital Dermatillomania. AB - Dermatillomania is a rare disease that seldom affects the genitals. Genital dermatillomania has not yet been recognized as a separate entity within the disease. The purpose of the report is to highlight a new facet of dermatillomania and inform urologists that dermatillomania could be a potential reason for genital ulcers. This report documents 2 cases of genital dermatillomania which vary in severity from mild (case 1), where the patient's ulcers healed after extensive counseling, to extremely dire (case 2), where the patient lost his penis after recurring ulcers and multiple reconstructive surgeries. Clinicians should be aware of the characteristics of dermatillomania to ensure that appropriate therapy can be promptly initiated to prevent morbidity. PMID- 29463979 TI - Patients' and Healthcare Personnel's Experiences of Health Coaching with Online Self-Management in the Renewing Health Project. AB - Background: Telehealth applications have shown positive effects for people with chronic conditions and their awareness of health. Objective: To describe patients' and healthcare personnel's experiences of using health coaching with online self-management in primary health care. Method: A pragmatic randomised controlled trial was conducted. Patients in the intervention group measured and reported medical parameters such as blood pressure, blood glucose, prothrombin complex (PK) values, and 2-channel ECG. Data were collected through a questionnaire, individual interviews with patients, and focus group discussions with healthcare personnel. The questionnaire was analysed using statistics; texts from interviews and focus groups were analysed using content analysis. Findings: Patients were satisfied and believed that the intervention had enhanced their care and increased accessibility without causing concerns about privacy. Although being positive, patients commented the lack of support and feedback from healthcare personnel. Healthcare personnel regarded the intervention valuable for the patients' abilities to perform self-management healthcare tasks but preferred that patients did so without them supporting the patients. Conclusion: Patients expressed satisfaction and acceptance regarding the use of the application. It seems that healthcare personnel are convinced about the benefits for patients and the potential for the intervention but are not convinced about its benefits for healthcare organisations. PMID- 29463980 TI - Achieving the Recommended Endotracheal Tube Cuff Pressure: A Randomized Control Study Comparing Loss of Resistance Syringe to Pilot Balloon Palpation. AB - Background: Both under- and overinflation of endotracheal tube cuffs can result in significant harm to the patient. The optimal technique for establishing and maintaining safe cuff pressures (20-30 cmH2O) is the cuff pressure manometer, but this is not widely available, especially in resource-limited settings where its use is limited by cost of acquisition and maintenance. Therefore, anesthesia providers commonly rely on subjective methods to estimate safe endotracheal cuff pressure. This study set out to determine the efficacy of the loss of resistance syringe method at estimating endotracheal cuff pressures. Methods: This was a randomized clinical trial. We enrolled adult patients scheduled to undergo general anesthesia for elective surgery at Mulago Hospital, Uganda. Study participants were randomized to have their endotracheal cuff pressures estimated by either loss of resistance syringe or pilot balloon palpation. The pressures measured were recorded. Results: One hundred seventy-eight patients were analyzed. 66.3% (59/89) of patients in the loss of resistance group had cuff pressures in the recommended range compared with 22.5% (20/89) from the pilot balloon palpation method. This was statistically significant. Conclusion: The loss of resistance syringe method was superior to pilot balloon palpation at administering pressures in the recommended range. This method provides a viable option to cuff inflation. PMID- 29463981 TI - Exploring the Role of Estrogens in Lizard Spermatogenesis through the Study of Clomiphene and FSH Effects. AB - Spermatogenesis is a fascinating biological process aiming to generate haploid spermatozoa from diploid spermatogonia through a specific hormonal network between gonadotropins and steroids. Increasing evidence suggests that the primary female sex hormone estrogen plays an active role in this process. This research points out on the role of estrogen during lizard spermatogenesis by using three experimental approaches: (1) exposure to an analogue of nonsteroidal estrogen as Clomiphene citrate that acts both as estrogen agonist and antagonist; (2) exposure to the gonadotropin FSH; and (3) exposures to FSH followed by Clomiphene. Histological and immunohistochemical results demonstrate that in the lizard Podarcis sicula during the mating period, Clomiphene as well as FSH determines the breakdown of spermatogenesis and the epididymal regression, presumably through estrogens input as indirectly demonstrated by the appearance of ERalpha and vitellogenin in the liver. The ability of Clomiphene to restore the gonadal natural condition after FSH treatment is also demonstrated.

AB - Background: Adiponectin (APN) is an adipocyte-derived hormone that has peripheral beneficial effects. Although its receptors AdipoR1 and AdipoR2 are expressed in the brain, their function in neurons is poorly understood. The aims of this work were to describe the distribution of APN receptors in the olfactory bulb (OB) as well as the possible effects of APN injection on the insulin receptor (InsR) content and Akt kinase. Method: We performed the double immunofluorescence technique to describe the distribution of AdipoRs and the cellular type they were expressing. mRNA transcript and protein content were assessed by RT-PCR and Western blot, respectively. APN injection was performed to analyze its possible effect on the insulin pathway. Results: We found that AdipoRs were localized in all cell layers and in both neurons and astrocytes. We observed the presence of mRNA transcripts and immunoblot analysis confirmed the protein on the intact OB; APN injection in the OB resulted in a slight decrease of the total InsR and Akt phosphorylation and a reduction of phopho-InsR content. Conclusions: These data demonstrated that AdipoRs are expressed in OB regions, and APN injection could act as an insulin pathway modulator in the OB and thus possibly contribute to olfaction physiology.

AB - Limited nitrogen (N) content in the soil is a major challenge to sustainable and high crop production in many developing countries. The nitrogen fixing symbiosis of legumes with rhizobia plays an important role in supplying sufficient N for legumes and subsequent nonleguminous crops. To identify rhizobia strains which are suitable for bioinoculant production, characterization of rhizobia is a prerequisite. The objective of this study was to assess the morphological and genetic diversity of rhizobia that nodulates cowpea in agricultural soils of lower eastern Kenya. Twenty-eight rhizobia isolates were recovered from soil samples collected from farmers' fields in Machakos, Makueni, and Kitui counties in lower eastern Kenya and characterized based on morphological characteristics. Thirteen representative isolates were selected and characterized using BOX repetitive element PCR fingerprinting. Based on the dendrogram generated from morphological characteristics, the test isolates were distributed into two major clusters at a similarity of 75%. Phylogenetic tree, based on BOX repetitive element PCR, grouped the isolates into two clusters at 90% similarity level. The clustering of the isolates did not show a relationship to the origin of soil samples, although the isolates were genetically diverse. This study is a prerequisite to the selection of suitable cowpea rhizobia to develop bioinoculants for sustainable crop production in Kenya.

AB - Purpose: To develop generic optimization strategies for image reconstruction using graphical processing units (GPUs) in magnetic resonance imaging (MRI) and to exemplarily report on our experience with a highly accelerated implementation of the nonlinear inversion (NLINV) algorithm for dynamic MRI with high frame rates. Methods: The NLINV algorithm is optimized and ported to run on a multi-GPU single-node server. The algorithm is mapped to multiple GPUs by decomposing the data domain along the channel dimension. Furthermore, the algorithm is decomposed along the temporal domain by relaxing a temporal regularization constraint, allowing the algorithm to work on multiple frames in parallel. Finally, an autotuning method is presented that is capable of combining different decomposition variants to achieve optimal algorithm performance in different imaging scenarios. Results: The algorithm is successfully ported to a multi-GPU system and allows online image reconstruction with high frame rates. Real-time reconstruction with low latency and frame rates up to 30 frames per second is demonstrated. Conclusion: Novel parallel decomposition methods are presented which are applicable to many iterative algorithms for dynamic MRI. Using these methods to parallelize the NLINV algorithm on multiple GPUs, it is possible to achieve online image reconstruction with high frame rates. PMID- 29463985 TI - Involvement of Machine Learning for Breast Cancer Image Classification: A Survey. AB - Breast cancer is one of the largest causes of women's death in the world today. Advance engineering of natural image classification techniques and Artificial Intelligence methods has largely been used for the breast-image classification task. The involvement of digital image classification allows the doctor and the physicians a second opinion, and it saves the doctors' and physicians' time. Despite the various publications on breast image classification, very few review papers are available which provide a detailed description of breast cancer image classification techniques, feature extraction and selection procedures, classification measuring parameterizations, and image classification findings. We have put a special emphasis on the Convolutional Neural Network (CNN) method for breast image classification. Along with the CNN method we have also described the involvement of the conventional Neural Network (NN), Logic Based classifiers such as the Random Forest (RF) algorithm, Support Vector Machines (SVM), Bayesian methods, and a few of the semisupervised and unsupervised methods which have been used for breast image classification. PMID- 29463986 TI - Multiscale High-Level Feature Fusion for Histopathological Image Classification. AB - Histopathological image classification is one of the most important steps for disease diagnosis. We proposed a method for multiclass histopathological image classification based on deep convolutional neural network referred to as coding network. It can gain better representation for the histopathological image than only using coding network. The main process is that training a deep convolutional neural network is to extract high-level feature and fuse two convolutional layers' high-level feature as multiscale high-level feature. In order to gain better performance and high efficiency, we would employ sparse autoencoder (SAE) and principal components analysis (PCA) to reduce the dimensionality of multiscale high-level feature. We evaluate the proposed method on a real histopathological image dataset. Our results suggest that the proposed method is effective and outperforms the coding network. PMID- 29463987 TI - LET's sponge: How the lncRNA PFL promotes cardiac fibrosis. AB - Compared to their protein-coding counterparts, almost nothing is known about the role of long noncoding RNAs (lncRNAs) in cardiac fibrosis. In the current report, Liang and Pan et al. characterized the pro-fibrotic lncRNA PFL in respect to cardiac fibrosis in mice. PFL was upregulated in the hearts of mice after myocardial infarction and in fibrotic cardiac fibroblasts. Moreover, PFL competitively sponged the cardio-protective miRNA let-7d in cardiac fibroblasts. Knockdown of platelet activating factor receptor (PTAFR) was shown to affect the pro-fibrotic collagen production mediated by PFL. PTAFR overexpression also led to collagen production and RNA abundance of PTAFR was also regulated by miRNA let 7d. Therefore, the PFL/PTAFR/let-7d-dependent gene regulatory mechanism proposed by the authors manifests the hypothesis of competing endogenous RNAs to cardiac fibrosis. PMID- 29463988 TI - Sustained Release of Immunosuppressant by Nanoparticle-anchoring Hydrogel Scaffold Improved the Survival of Transplanted Stem Cells and Tissue Regeneration. AB - The outcome of scaffold-based stem cell transplantation remains unsatisfied due to the poor survival of transplanted cells. One of the major hurdles associated with the stem cell survival is the immune rejection, which can be effectively reduced by the use of immunosuppressant. However, ideal localized and sustained release of immunosuppressant is difficult to be realized, because it is arduous to hold the drug delivery system within scaffold for a long period of time. In the present study, the sustained release of immunosuppressant for the purpose of improving the survival of stem cells was successfully realized by a nanoparticle anchoring hydrogel scaffold we developed. Methods: Poly (lactic-co-glycolic acid) (PLGA) nanoparticles were modified with RADA16 (RNPs), a self-assembling peptide, and then anchored to a RADA16 hydrogel (RNPs + Gel). The immobilization of RNPs in hydrogel was measured in vitro and in vivo, including the Brownian motion and cumulative leakage of RNPs and the in vivo retention of injected RNPs with hydrogel. Tacrolimus, as a typical immunosuppressant, was encapsulated in RNPs (T RNPs) that were anchored to the hydrogel and its release behavior were studied. Endothelial progenitor cells (EPCs), as model stem cells, were cultured in the T RNPs-anchoring hydrogel to test the immune-suppressing effect. The cytotoxicity of the scaffold against EPCs was also measured compared with free tacrolimus loaded hydrogel. The therapeutic efficacy of the scaffold laden with EPCs on the hind limb ischemia was further evaluated in mice. Results: The Brownian motion and cumulative leakage of RNPs were significantly decreased compared with the un modified nanoparticles (NPs). The in vivo retention of injected RNPs with hydrogel was obviously longer than that of NPs with hydrogel. The release of tacrolimus from T-RNPs + Gel could be sustained for 28 days. Compared with free tacrolimus-loaded hydrogel, the immune responses were significantly reduced and the survival of EPCs was greatly improved both in vitro and in vivo. The results of histological evaluation, including accumulation of immune cells and deposition of anti-graft antibodies, further revealed significantly lessened immune rejection in T-RNPs-anchoring hydrogel group compared with other groups. In pharmacodynamics study, the scaffold laden with EPCs was applied to treat hind limb ischemia in mice and significantly promoted the blood perfusion (~91 % versus ~36 % in control group). Conclusion: The nanoparticle-anchoring hydrogel scaffold is promising for localized immunosuppressant release, thereby can enhance the survival of transplanted cells and finally lead to successful tissue regeneration. PMID- 29463989 TI - Combined delivery of sorafenib and a MEK inhibitor using CXCR4-targeted nanoparticles reduces hepatic fibrosis and prevents tumor development. AB - Liver damage and fibrosis are precursors of hepatocellular carcinoma (HCC). In HCC patients, sorafenib-a multikinase inhibitor drug-has been reported to exert anti-fibrotic activity. However, incomplete inhibition of RAF activity by sorafenib may also induce paradoxical activation of the mitogen-activated protein kinase (MAPK) pathway in malignant cells. The consequence of this effect in non malignant disease (hepatic fibrosis) remains unknown. This study aimed to examine the effects of sorafenib on activated hepatic stellate cells (HSCs), and develop effective therapeutic approaches to treat liver fibrosis and prevent cancer development. Methods: We first examined the effects of sorafenib in combination with MEK inhibitors on fibrosis pathogenesis in vitro and in vivo. To improve the bioavailability and absorption by activated HSCs, we developed CXCR4-targeted nanoparticles (NPs) to co-deliver sorafenib and a MEK inhibitor to mice with liver damage. Results: We found that sorafenib induced MAPK activation in HSCs, and promoted their myofibroblast differentiation. Combining sorafenib with a MEK inhibitor suppressed both paradoxical MAPK activation and HSC activation in vitro, and alleviated liver fibrosis in a CCl4-induced murine model of liver damage. Furthermore, treatment with sorafenib/MEK inhibitor-loaded CXCR4-targeted NPs significantly suppressed hepatic fibrosis progression and further prevented fibrosis-associated HCC development and liver metastasis. Conclusions: Our results show that combined delivery of sorafenib and a MEK inhibitor via CXCR4 targeted NPs can prevent activation of ERK in activated HSCs and has anti fibrotic effects in the CCl4-induced murine model. Targeting HSCs represents a promising strategy to prevent the development and progression of fibrosis associated HCC. PMID- 29463990 TI - Mesenchymal Stromal/stem Cell-derived Extracellular Vesicles Promote Human Cartilage Regeneration In Vitro. AB - : Osteoarthritis (OA) is a rheumatic disease leading to chronic pain and disability with no effective treatment available. Recently, allogeneic human mesenchymal stromal/stem cells (MSC) entered clinical trials as a novel therapy for OA. Increasing evidence suggests that therapeutic efficacy of MSC depends on paracrine signalling. Here we investigated the role of extracellular vesicles (EVs) secreted by human bone marrow derived MSC (BMMSC) in human OA cartilage repair. METHODS: To test the effect of BMMSC-EVs on OA cartilage inflammation, TNF-alpha-stimulated OA chondrocyte monolayer cultures were treated with BMMSC EVs and pro-inflammatory gene expression was measured by qRT-PCR after 48 h. To assess the impact of BMMSC-EVs on cartilage regeneration, BMMSC-EVs were added to the regeneration cultures of human OA chondrocytes, which were analyzed after 4 weeks for glycosaminoglycan content by 1,9-dimethylmethylene blue (DMMB) assay. Furthermore, paraffin sections of the regenerated tissue were stained for proteoglycans (safranin-O) and type II collagen (immunostaining). RESULTS: We show that BMMSC-EVs inhibit the adverse effects of inflammatory mediators on cartilage homeostasis. When co-cultured with OA chondrocytes, BMMSC-EVs abrogated the TNF-alpha-mediated upregulation of COX2 and pro-inflammatory interleukins and inhibited TNF-alpha-induced collagenase activity. BMMSC-EVs also promoted cartilage regeneration in vitro. Addition of BMMSC-EVs to cultures of chondrocytes isolated from OA patients stimulated production of proteoglycans and type II collagen by these cells. CONCLUSION: Our data demonstrate that BMMSC-EVs can be important mediators of cartilage repair and hold great promise as a novel therapeutic for cartilage regeneration and osteoarthritis. PMID- 29463991 TI - Cancer-associated Fibroblast-derived IL-6 Promotes Head and Neck Cancer Progression via the Osteopontin-NF-kappa B Signaling Pathway. AB - Osteopontin (OPN), a chemokine-like protein, plays a crucial role in the proliferation and metastasis of various cancers. However, how tumor stroma modulates the expression of neoplastic OPN and the multifaceted roles of OPN in head and neck cancer (HNC) are unclear. In this study, we tried to investigate the bridging role of OPN between tumor stroma and cancer cells. Methods: Immunohistochemical staining and quantitative real-time PCR were used to detect OPN expression in HNC tissues, and the correlations between OPN expression and clinicopathologic features were then analyzed. We used a co-culture assay to study the modulatory role of IL-6 on OPN expression and immunoprecipitation analysis was used to determine the endogenous interaction between OPN and integrin alphavbeta3. Furthermore, a xenograft assay was carried out to confirm the tumor-promoting role and the potential therapeutic value of OPN in HNC. Results: We found that OPN was significantly up-regulated in HNCs, and the elevated OPN was correlated with poor prognosis. Moreover, we identified IL-6 secreted by cancer-associated fibroblasts (CAFs) as the major upstream molecule that triggers the induction of neoplastic OPN. As such, during the interaction of fibroblasts and cancer cells, the increased neoplastic OPN induced by stromal IL 6 accelerated the growth, migration and invasion of cancer cells. More importantly, we also showed that soluble OPN could promote HNC progression via the integrin alphavbeta3-NF-kappa B pathway, and the combination of OPN and IL-6 had a better prognostic and diagnostic performance in HNC than either molecule alone. Conclusion: Our study identified a novel modulatory role for OPN in HNC progression and further demonstrated that the combination of OPN and IL-6 might be a promising prognostic and diagnostic indicator as well as a potential cancer therapeutic target. PMID- 29463992 TI - Investigating the Intracellular Behaviors of Liposomal Nanohybrids via SERS: Insights into the Influence of Metal Nanoparticles. AB - The recent proposition to combine liposomes with nanoparticles presents great opportunities to develop multifunctional drug delivery platforms. Although impressive progress has been made, attempts to elucidate the role nanoparticles play in the integral nanohybrids are still rather limited. Here, using surface enhanced Raman scattering (SERS) technique, we investigate the influence of metal nanoparticles on the liposomal properties, ranging from drug release to intracellular movement. Specifically, we prepared SERS-active nanohybrids by attaching metal nanoparticles to liposomes and employed SERS signals to explore the intracellular behavior of the nanohybrids. Once deposited on the cell membrane, the nanohybrids entered tumor cells via clathrin-mediated endocytosis and then moved to lysosomes. In comparison with pure liposomes, metal nanoparticles in the nanohybrids had little influence on the properties of liposomes. This study fills the gap of the function of nanoparticles in the overall nanohybrids, which provides a significant prerequisite for efficient drug delivery in therapeutic applications. PMID- 29463993 TI - All-in-One Theranostic Nanoplatform Based on Hollow MoSx for Photothermally maneuvered Oxygen Self-enriched Photodynamic Therapy. AB - : Photodynamic therapy (PDT) kills cancer cells by converting tumor-dissolved oxygen into reactive singlet oxygen (1O2) using a photosensitizer under laser irradiation. However, pre-existing hypoxia in tumors and oxygen consumption during PDT can result in an inadequate oxygen supply, which in turn hampers PDT efficacy. Herein, an O2 self-sufficient nanotheranostic platform based on hollow MoSx nanoparticles (HMoSx) with oxygen-saturated perfluorohexane (O2@PFH) and surface-modified human serum albumin (HSA)/chloride aluminium phthalocyanine (AlPc) (O2@PFH@HMoSx-HSA/AlPc), has been designed for the imaging and oxygen self enriched photodynamic therapy (Oxy-PDT) of cancer. METHODS: The in vitro anti cancer activity and intracellular 1O2 generation performance of the nanoparticles were examined using 4T1 cells. We also evaluated the multimodal imaging capabilities and anti-tumor efficiency of the prepared nanoparticles in vivo using a 4T1 tumor-bearing nude mouse model. RESULTS: This nanoplatform could achieve the distinct in vivo fluorescence (FL)/photoacoustic (PA)/X-ray computed tomography (CT) triple-model imaging-guided photothermally-maneuvered Oxy-PDT. Interestingly, the fluorescence and Oxy-PDT properties of O2@PFH@HMoSx-HSA/AlPc were considerably quenched; however, photothermal activation by 670 nm laser irradiation induced a significant increase in temperature, which empowered the Oxy-PDT effect of the nanoparticles. In this study, O2@PFH@HMoSx-HSA/AlPc demonstrated a great potential to image and treat tumors both in vitro and in vivo, showing complete tumor-inhibition over 16 days after treatment in the 4T1 tumor model. CONCLUSION: O2@PFH@HMoSx-HSA/AlPc is promising to be used as novel multifunctional theranostic nanoagent for triple-modal imaging as well as single wavelength NIR laser triggered PTT/Oxy-PDT synergistic therapy. PMID- 29463994 TI - The Homeotic Protein SIX3 Suppresses Carcinogenesis and Metastasis through Recruiting the LSD1/NuRD(MTA3) Complex. AB - : The homeodomain transcription factor SIX3 was recently reported to be a negative regulator of the Wnt pathway and has an emerging role in cancer. However, how SIX3 contributes to tumorigenesis and metastasis is poorly understood. METHODS: We employed affinity purification and mass spectrometry (MS) to identify the proteins physically associated with SIX3. Genome-wide analysis of the SIX3/LSD1/NuRD(MTA3) complex using a chromatin immunoprecipitation-on-chip approach identified a cohort of target genes including WNT1 and FOXC2, which are critically involved in cell proliferation and epithelial-to-mesenchymal transition. Also, we used flow cytometry, growth curve analysis, EdU incorporation assay, colony formation assays, trans-well invasion assays, immunohistochemical staining and in vivo bioluminescence assay to investigate the function of SIX3 in tumorigenesis. RESULTS: We demonstrate that the SIX3/LSD1/NuRD(MTA3) complex inhibits carcinogenesis in breast cancer cells and suppresses metastasis in breast cancer. SIX3 expression is downregulated in various human cancers and high SIX3 is correlated with improved prognosis. CONCLUSION: Our study revealed an important mechanistic link between the loss of function of SIX3 and tumor progression, identified a molecular basis for the opposing actions of MTA1 and MTA3, and may provide new potential prognostic indicators and targets for cancer therapy. PMID- 29463995 TI - O2-generating MnO2 nanoparticles for enhanced photodynamic therapy of bladder cancer by ameliorating hypoxia. AB - Photodynamic therapy (PDT) is an emerging effective treatment for cancer. However, the great promise of PDT for bladder cancer therapy has not yet been realized because of tumor hypoxia. To address this challenge, we fabricated O2 generating HSA-MnO2-Ce6 NPs (HSA for human serum albumin, Ce6 for chlorin e6, and NPs for nanoparticles) to overcome tumor hypoxia and thus enhance the photodynamic effect for bladder cancer therapy. Methods: The HSA-MnO2-Ce6 NPs were prepared. We investigated the O2 generation of NPs in vitro and in vivo. The orthotopic bladder cancer model in C57BL/6 mice was established for in vivo study, and dual-modal imaging of NPs were demonstrated. Therapeutic efficacy of NPs for bladder cancer was evaluated. Results: HSA-MnO2-Ce6 NPs had an excellent performance in generating O2in vitro upon reaction with H2O2 at endogenous levels. Moreover, 1O2 generation was increased two-fold by using HSA-MnO2-Ce6 NPs instead of HSA-Ce6 NPs in the presence of H2O2 under 660 nm laser irradiation. In vitro cell viability assays showed that HSA-MnO2-Ce6 NPs themselves were non toxic but greatly enhanced PDT effects on bladder cancer cells under laser irradiation. In vivo near-infrared (NIR) fluorescence and magnetic resonance (MR) imaging suggested the excellent bladder tumor-targeting property of HSA-MnO2-Ce6 NPs. O2 content in orthotopic bladder cancer was increased 3.5-fold after injection of HSA-MnO2-Ce6 NPs as compared with pre-injection. Given the excellent tumor-targeting ability and negligible toxicity, HSA-MnO2-Ce6 NPs were then used to treat orthotopic bladder cancer by PDT. The PDT with HSA-MnO2-Ce6 NPs showed remarkably improved therapeutic efficacy and significantly prolonged lifetime of mice as compared with controls. Conclusion: This study not only demonstrated the great potential of HSA-MnO2-Ce6 NPs for bladder cancer photodynamic ablation but also provided a new therapeutic strategy to overcoming tumor hypoxia. PMID- 29463996 TI - Black Phosphorus and its Biomedical Applications. AB - Black phosphorus (BP), also known as phosphorene, has attracted recent scientific attention since its first successful exfoliation in 2014 owing to its unique structure and properties. In particular, its exceptional attributes, such as the excellent optical and mechanical properties, electrical conductivity and electron transfer capacity, contribute to its increasing demand as an alternative to graphene-based materials in biomedical applications. Although the outlook of this material seems promising, its practical applications are still highly challenging. In this review article, we discuss the unique properties of BP, which make it a potential platform for biomedical applications compared to other 2D materials, including graphene, molybdenum disulphide (MoS2), tungsten diselenide (WSe2) and hexagonal boron nitride (h-BN). We then introduce various synthesis methods of BP and review its latest progress in biomedical applications, such as biosensing, drug delivery, photoacoustic imaging and cancer therapies (i.e., photothermal and photodynamic therapies). Lastly, the existing challenges and future perspective of BP in biomedical applications are briefly discussed. PMID- 29463997 TI - Targeting ALDH2 for Therapeutic Interventions in Chronic Pain-Related Myocardial Ischemic Susceptibility. AB - Clinical observations have demonstrated a link between chronic pain and increased ischemic heart disease mortality, but the mechanisms remain elusive. Reactive aldehydes have recently been confirmed as a new player in pain pathologies, while our previous study demonstrated that reactive aldehydes (4-HNE) induced carbonyl stress contributing to myocardial ischemic intolerance. The aim of this study was to explore whether chronic pain increases susceptibility to myocardial ischemia/reperfusion (MI/R) injury and to investigate the underlying mechanisms focusing on toxic aldehyde and carbonyl stress. Methods: Chronic pain was induced by chronic compression of the dorsal root ganglion (CCD). After 2 weeks CCD, aldehyde dehydrogenase (ALDH2) KO or wild-type (WT) littermate mice were then subjected to in vivo MI/R. Results: In CCD-WT mice, heightened nociception paralleled circulating aldehyde (4-HNE) accumulation and cardiac protein carbonylation. Mechanistically, CCD-induced 4-HNE overload provoked cardiac Sirtuin 1 (SIRT1) carbonylative inactivation and inhibited Liver kinase B1 (LKB1) - AMP-activated protein kinase (LKB1-AMPK) interaction, which resulted in exacerbated MI/R injury and higher mortality compared with non-CCD WT mice. ALDH2 deficiency further aggravated CCD-induced susceptibility to MI/R injury. Exogenous 4-HNE exposure in peripheral tissue mimicked chronic pain-induced aldehyde overload, elicited sustained allodynia and increased MI/R injury. However, cardiac-specific ALDH2 upregulation by AAV9-cTNT-mediated gene delivery significantly ameliorated chronic pain-induced SIRT1 carbonylative inactivation and decreased MI/R injury (minor infarct size, less apoptosis, and improved cardiac function). Conclusion: Collectively, chronic pain-enhanced carbonyl stress promotes myocardial ischemic intolerance by SIRT1 carbonylative inactivation and impairment of LKB1-AMPK interaction. ALDH2 activation and prevention of protein carbonylation may be a potential therapeutic target for myocardial ischemic vulnerability in chronic pain patients. Our results newly provided overlapping cellular mechanisms of chronic pain and myocardial dysfunction interplay. PMID- 29463998 TI - Octopod PtCu Nanoframe for Dual-Modal Imaging-Guided Synergistic Photothermal Radiotherapy. AB - Heavy atom nanoparticles have high X-ray absorption capacity and near infrared (NIR) photothermal conversion efficiency, which could be used as radio sensitizers. We hypothesized that concave PtCu octopod nanoframes (OPCNs) would be an efficient nanoplatform for synergistic radio-photothermal tumor ablation. Methods: In this study, we newly exploited a folic acid-receptor (FR) mediated photothermal radiotherapy nanoagent base on OPCNs. OPCNs were synthesized with a hydrothermal method and then modified with polyethylene glycol (PEG) and folic acid (FA). A series of physical and chemical characterizations, cytotoxicity, targeting potential, endocytosis mechanism, biodistribution, systematic toxicological evaluation, pharmacokinetics, applications of OPCNs-PEG-FA for in vitro and in vivo infrared thermal imaging (ITI)/photoacoustic imaging (PAI) dual modal imaging and synergistic photothermal radiotherapy against tumor were carried out. Results: The OPCNs-PEG-FA demonstrated good biocompatibility, strong NIR absorption and X-ray radio-sensitization, which enabling it to track and visualize tumor in vivo via ITI/PAI dual-modal imaging. Moreover, the as synthesized OPCNs-PEG-FA exhibited remarkable photothermal therapy (PTT) and radiotherapy (RT) synergistic tumor inhibition when treated with NIR laser and X ray. Conclusion: A novel multifunctional theranostic nanoplatform based on OPCNs was designed and developed for dual-modal image-guided synergistic tumor photothermal radiotherapy. PMID- 29464000 TI - Nondestructive Analysis of Tumor-Associated Membrane Protein Integrating Imaging and Amplified Detection in situ Based on Dual-Labeled DNAzyme. AB - Comprehensive analysis of the expression level and location of tumor-associated membrane proteins (TMPs) is of vital importance for the profiling of tumor cells. Currently, two kinds of independent techniques, i.e. ex situ detection and in situ imaging, are usually required for the quantification and localization of TMPs respectively, resulting in some inevitable problems. Methods: Herein, based on a well-designed and fluorophore-labeled DNAzyme, we develop an integrated and facile method, in which imaging and quantification of TMPs in situ are achieved simultaneously in a single system. The labeled DNAzyme not only produces localized fluorescence for the visualization of TMPs but also catalyzes the cleavage of a substrate to produce quantitative fluorescent signals that can be collected from solution for the sensitive detection of TMPs. Results: Results from the DNAzyme-based in situ imaging and quantification of TMPs match well with traditional immunofluorescence and western blotting. In addition to the advantage of two-in-one, the DNAzyme-based method is highly sensitivity, allowing the detection of TMPs in only 100 cells. Moreover, the method is nondestructive. Cells after analysis could retain their physiological activity and could be cultured for other applications. Conclusion: The integrated system provides solid results for both imaging and quantification of TMPs, making it a competitive method over some traditional techniques for the analysis of TMPs, which offers potential application as a toolbox in the future. PMID- 29463999 TI - Stimuli-Responsive Nanomedicines for Overcoming Cancer Multidrug Resistance. AB - Chemotherapy is still a main option for cancer therapy, but its efficacy is often unsatisfying due to multidrug resistance (MDR). The tumor microenvironment is considered a dominant factor causing MDR. Stimuli-responsive nanomedicines exhibit many superiorities for reversal of MDR. As smart systems, stimuli responsive nanomedicines are desirable for achieving site-specific accumulation and triggered drug release in response to slight changes in physicochemical properties in pathological conditions or to exogenous stimuli. In this review, we highlight the current progress of various nanomedicines with different stimuli responsive capabilities for overcoming MDR. The materials, design, construction as well as efficacy in overcoming MDR of these nanomedicines are discussed. Eventually, we look forward to forthcoming intelligent nanoparticle systems with new mechanisms to deliver drugs for practical applications in conquering cancer MDR. PMID- 29464001 TI - PIWIL3/OIP5-AS1/miR-367-3p/CEBPA feedback loop regulates the biological behavior of glioma cells. AB - Rationale: PIWI-interacting RNAs (piRNAs), a class of newly discovered small RNA molecules that function by binding to the Argonaute protein family (i.e., the PIWIL protein subfamily), and long noncoding RNAs (lncRNA) are implicated in several cancers. However, the detailed roles of ncRNAs in glioma remain unclear. Methods: The expression of PIWIL3, piR-30188, OIP5-AS1, miR-367, CEBPA and TRAF4 were measured in glioma tissues and cells. The role of PIWIL3/OIP5-AS1/miR-367 3p/CEBPA feedback loop was evaluated in cell and animal models. The association of the above molecules was analyzed. Results: Over-expression of PIWIL3, piR 30188 and miR-367-3p or knockdown of OIP5-AS1 resulted in inhibition of glioma cells progression. Binding sites between piR-30188 and OIP5-AS1 as well as between OIP5-AS1 and miR-367-3p were confirmed by RNA immunoprecipitation and luciferase assays. OIP5-AS1 knockdown or miR-367-3p over-expression contributed to a decrease in CEBPA (CCAAT/enhancer binding protein alpha) protein. Furthermore, CEBPA was detected as a target of miR-367-3p and played an oncogenic role in glioma. Treatment with CEBPA and miR-367-3p resulted in the modulation of downstream TRAF4 (TNF receptor-associated factor 4). PIWIL3 was also a target of CEBPA, forming a positive feedback loop in the growth regulation of glioma cells. Significantly, knockdown of OIP5-AS1 combined with over-expression of PIWIL3 and miR-367-3p resulted in tumor regression and extended survival in vivo. Conclusion: These results identified a novel molecular pathway in glioma cells that may provide a potential innovative approach for tumor therapy. PMID- 29464002 TI - MiR-205-5p and miR-342-3p cooperate in the repression of the E2F1 transcription factor in the context of anticancer chemotherapy resistance. AB - High rates of lethal outcome in tumour metastasis are associated with the acquisition of invasiveness and chemoresistance. Several clinical studies indicate that E2F1 overexpression across high-grade tumours culminates in unfavourable prognosis and chemoresistance in patients. Thus, fine-tuning the expression of E2F1 could be a promising approach for treating patients showing chemoresistance. Methods: We integrated bioinformatics, structural and kinetic modelling, and experiments to study cooperative regulation of E2F1 by microRNA (miRNA) pairs in the context of anticancer chemotherapy resistance. Results: We showed that an enhanced E2F1 repression efficiency can be achieved in chemoresistant tumour cells through two cooperating miRNAs. Sequence and structural information were used to identify potential miRNA pairs that can form tertiary structures with E2F1 mRNA. We then employed molecular dynamics simulations to show that among the identified triplexes, miR-205-5p and miR-342 3p can form the most stable triplex with E2F1 mRNA. A mathematical model simulating the E2F1 regulation by the cooperative miRNAs predicted enhanced E2F1 repression, a feature that was verified by in vitro experiments. Finally, we integrated this cooperative miRNA regulation into a more comprehensive network to account for E2F1-related chemoresistance in tumour cells. The network model simulations and experimental data indicate the ability of enhanced expression of both miR-205-5p and miR-342-3p to decrease tumour chemoresistance by cooperatively repressing E2F1. Conclusions: Our results suggest that pairs of cooperating miRNAs could be used as potential RNA therapeutics to reduce E2F1 related chemoresistance. PMID- 29464003 TI - 68Ga-BBN-RGD PET/CT for GRPR and Integrin alphavbeta3 Imaging in Patients with Breast Cancer. AB - Purpose: This study was to assess a gastrin-releasing peptide receptor (GRPR) and integrin alphavbeta3 dual targeting tracer 68Ga-BBN-RGD for positron emission tomography (PET)/computed tomography (CT) imaging of breast cancer and metastasis. Materials and Methods: Twenty-two female patients were recruited either with suspected breast cancer on screening mammography (n = 16) or underwent breast cancer radical mastectomy (n = 6). All the 22 patients underwent PET/CT at 30-45 min after intravenous injection of 68Ga-BBN-RGD. Eleven out of 22 patients also accepted 68Ga-BBN PET/CT within 2 weeks for comparison. A final diagnosis was made based on the histopathologic examination of surgical excision or biopsy. Results: Both the primary cancer and metastases showed positive 68Ga BBN-RGD accumulation. The T/B ratios of 68Ga-BBN-RGD accumulation were 2.10 to 9.44 in primary cancer and 1.10 to 3.71 in axillary lymph node metastasis, 3.80 to 10.7 in distant lymph nodes, 2.70 to 5.35 in lung metastasis and 3.17 to 22.8 in bone metastasis, respectively. For primary lesions, the SUVmax from 68Ga-BBN RGD PET in ER positive group was higher than that in ER negative group (P < 0.01). For both primary and metastatic lesions, SUVmean quantified from 68Ga-BBN RGD PET correlated well with both GRPR expression and integrin alphavbeta3 expression. Conclusion: This study demonstrated significant uptake of a new type of dual integrin alphavbeta3 and GRPR targeting radiotracer in both the primary lesion and the metastases of breast cancer. 68Ga-BBN-RGD PET/CT may be of great value in discerning both primary breast cancers, axillary lymph node metastasis and distant metastases. PMID- 29464005 TI - Non-invasive monitoring of in vivo hydrogel degradation and cartilage regeneration by multiparametric MR imaging. AB - Numerous biodegradable hydrogels for cartilage regeneration have been widely used in the field of tissue engineering. However, to non-invasively monitor hydrogel degradation and efficiently evaluate cartilage restoration in situ is still challenging. Methods: A ultrasmall superparamagnetic iron oxide (USPIO)-labeled cellulose nanocrystal (CNC)/silk fibroin (SF)-blended hydrogel system was developed to monitor hydrogel degradation during cartilage regeneration. The physicochemical characterization and biocompatibility of the hydrogel were evaluated in vitro. The in vivo hydrogel degradation and cartilage regeneration of different implants were assessed using multiparametric magnetic resonance imaging (MRI) and further confirmed by histological analysis in a rabbit cartilage defect model for 3 months. Results: USPIO-labeled hydrogels showed sufficient MR contrast enhancement and retained stability without loss of the relaxation rate. Neither the mechanical properties of the hydrogels nor the proliferation of bone-marrow mesenchymal stem cells (BMSCs) were affected by USPIO labeling in vitro. CNC/SF hydrogels with BMSCs degraded more quickly than the acellular hydrogels as reflected by the MR relaxation rate trends in vivo. The morphology of neocartilage was noninvasively visualized by the three dimensional water-selective cartilage MRI scan sequence, and the cartilage repair was further demonstrated by macroscopic and histological observations. Conclusion: This USPIO-labeled CNC/SF hydrogel system provides a new perspective on image-guided tissue engineering for cartilage regeneration. PMID- 29464004 TI - Biomimetic nanoparticles with enhanced affinity towards activated endothelium as versatile tools for theranostic drug delivery. AB - Activation of the vascular endothelium is characterized by increased expression of vascular adhesion molecules and chemokines. This activation occurs early in the progression of several diseases and triggers the recruitment of leukocytes. Inspired by the tropism of leukocytes, we investigated leukocyte-based biomimetic nanoparticles (i.e., leukosomes) as a novel theranostic platform for inflammatory diseases. Methods: Leukosomes were assembled by combining phospholipids and membrane proteins from leukocytes. For imaging applications, phospholipids modified with rhodamine and gadolinium were used. Leukosomes incubated with antibodies blocking lymphocyte function-associated antigen 1 (LFA-1) and CD45 were administered to explore their roles in targeting inflammation. In addition, relaxometric assessment of NPs was evaluated. Results: Liposomes and leukosomes were both spherical in shape with sizes ranging from 140-170 nm. Both NPs successfully integrated 8 and 13 ug of rhodamine and gadolinium, respectively, and demonstrated less than 4% variation in physicochemical features. Leukosomes demonstrated a 16-fold increase in breast tumor accumulation relative to liposomes. Furthermore, quantification of leukosomes in tumor vessels demonstrated a 4.5-fold increase in vessel lumens and a 14-fold increase in vessel walls. Investigating the targeting mechanism of action revealed that blockage of LFA-1 on leukosomes resulted in a 95% decrease in tumor accumulation. Whereas blockage of CD45 yielded a 60% decrease in targeting and significant increases in liver and spleen accumulation. In addition, when administered in mice with atherosclerotic plaques, leukosomes exhibited a 4-fold increase in the targeting of inflammatory vascular lesions. Lastly, relaxometric assessment of NPs demonstrated that the incorporation of membrane proteins into leukosomes did not impact the r1 and r2 relaxivities of the NPs, demonstrating 6 and 30 mM-1s-1, respectively. Conclusion: Our study demonstrates the ability of leukosomes to target activated vasculature and exhibit superior accumulation in tumors and vascular lesions. The versatility of the phospholipid backbone within leukosomes permits the incorporation of various contrast agents. Furthermore, leukosomes can potentially be loaded with therapeutics possessing diverse physical properties and thus warrant further investigation toward the development of powerful theranostic agents. PMID- 29464006 TI - Delivery of Sonic Hedgehog Gene Repressed Irradiation-induced Cellular Senescence in Salivary Glands by Promoting DNA Repair and Reducing Oxidative Stress. AB - Rationale: Irreversible hypofunction of salivary glands or xerostomia is common in head and neck cancer survivors treated with radiotherapy even when various new techniques are applied to minimize the irradiation (IR) damage. This condition severely impairs the quality of life of patients and can only be temporarily relieved with current treatments. We found recently that transient expression of Sonic Hedgehog (Shh) in salivary glands after IR rescued salivary function, but the underlying mechanisms are not totally clear. Methods: We generated a mouse model of IR-induced hyposalivation, and delivered adenoviral vectors carrying Shh or control GFP gene into submandibular glands (SMGs) via retrograde ductal instillation 3 days after IR. The cellular senescence was evaluated by senescence associated beta-galactosidase assay and the expression of senescence markers. The underlying mechanisms were explored by examining DNA damage, oxidative stress, and the expression of related genes by qRT-PCR, Western blot and immunofluorescent staining. Results: Shh gene transfer repressed IR-induced cellular senescence by promoting DNA repair and decreasing oxidative stress, which is mediated through upregulating expression of genes related to DNA repair such as survivin and miR-21 and repressing expression of pro-senescence gene Gdf15 likely downstream of miR-21. Conclusion: Repressing cellular senescence contributes to the rescue of IR-induced hyposalivation by transient activation of Hh signaling, which is related to enhanced DNA repair and decreased oxidative stress in SMGs. PMID- 29464007 TI - Diagnosis of LVAD Thrombus using a High-Avidity Fibrin-Specific 99mTc Probe. AB - Treatment of advanced heart failure with implantable LVADs is increasing, driven by profound unmet patient need despite potential serious complications: bleeding, infection, and thrombus. The experimental objective was to develop a sensitive imaging approach to assess early thrombus accumulation in LVADs under operational high flow and high shear rates. Methods: A monomeric bifunctional ligand with a fibrin-specific peptide, a short spacer, and 99mTc chelating amino acid sequence (F1A) was developed and compared to its tetrameric PEG analogue (F4A). Results:99mTc attenuation by LVAD titanium (1 mm) was 23%. 99mTc-F1A affinity to fibrin was Kd ~10 uM, whereas, the bound 99mTc-F4A probe was not displaced by F1A (120,000:1). Human plasma interfered with 99mTc-F1A binding to fibrin clot (p<0.05) in vitro, whereas, 99mTc-F4A targeting was unaffected. The pharmacokinetic half-life of 99mTc-F4A was 28% faster (124+/-41 min) than 99mTc F1A (176+/-26 min) with both being bioeliminated through the urinary system with negligible liver or spleen biodistribution. In mice with carotid thrombus, 99mTc F4A binding to the injured carotid was much greater (16.3+/-3.3 %ID/g, p=0.01) than that measured with an irrelevant negative control, 99mTc-I4A (3.4+/-1.6 %ID/g). In an LVAD mock flow-loop (1:1, PBS:human plasma:heparin) operating at maximal flow rate, 99mTc-F4A bound well to phantom clots in 2 min (p<0.05), whereas 99mTc-F1A had negligible targeting. Excised LVADs from patients undergoing pump exchange or heart transplant were rewired, studied in the mock flow loop, and found to have spatially variable fibrin accumulations in the inlet and outlet cannulas and bearings. Conclusions:99mTc-F4A is a high-avidity prototype probe for characterizing thrombus in LVADs that is anticipated to help optimize anticoagulation, reduce thromboembolic events, and minimize pump exchange. PMID- 29464008 TI - LncRNA PFL contributes to cardiac fibrosis by acting as a competing endogenous RNA of let-7d. AB - Rationale: Cardiac fibrosis is associated with various cardiovascular diseases and can eventually lead to heart failure. Dysregulation of long non-coding RNAs (lncRNAs) has recently been recognized as one of the key mechanisms involved in cardiac diseases. However, the potential roles and underlying mechanisms of lncRNAs in cardiac fibrosis have not been explicitly delineated. Methods and Results: Using a combination of in vitro and in vivo studies, we identified a lncRNA NONMMUT022555, which is designated as a pro-fibrotic lncRNA (PFL), and revealed that PFL is up-regulated in the hearts of mice in response to myocardial infarction (MI) as well as in the fibrotic cardiac fibroblasts (CFs). We found that knockdown of PFL by adenoviruses carrying shRNA attenuated cardiac interstitial fibrosis and improved ejection fraction (EF) and fractional shortening (FS) in MI mice. Further study showed that forced expression of PFL promoted proliferation, fibroblast-myofibroblast transition and fibrogenesis in mice CFs by regulating let-7d, whereas silencing PFL mitigated TGF-beta1-induced myofibroblast generation and fibrogenesis. More importantly, PFL acted as a competitive endogenous RNA (ceRNA) of let-7d, as forced expression of PFL reduced the expression and activity of let-7d. Moreover, let-7d levels were decreased in the MI mice and in fibrotic CFs. Inhibition of let-7d resulted in fibrogenesis in CFs, whereas forced expression of let-7d abated fibrogenesis through targeting platelet-activating factor receptor (Ptafr). Furthermore, overexpression of let 7d by adenoviruses carrying let-7d precursor impeded cardiac fibrosis and improved cardiac function in MI mice. Conclusion: Taken together, our study elucidated the role and mechanism of PFL in cardiac fibrosis, indicating the potential role of PFL inhibition as a novel therapy for cardiac fibrosis. PMID- 29464009 TI - Determination of glycated albumin using boronic acid-derived agarose beads on paper-based devices. AB - Self-monitoring of glycated albumin (GA), a useful glycemic marker, is an established method for preventing diabetes complications. Here, the paper-based lateral flow assay devices were developed for the sensitive detection of GA and the total human serum albumin (tHSA) in self-monitoring diabetes patients. Boronic acid-derived agarose beads were packed into a hole on a lateral flow channel. These well-coordinated agarose beads were used to capture GA through specific cis-diol interactions and to enhance the colorimetric signals by concentrating the target molecules. The devices exhibited large dynamic ranges (from 10 MUg/ml to 10 mg/ml for GA and from 10 mg/ml to 50 mg/ml for tHSA) and low detection limits (7.1 MUg/ml for GA and 4.7 mg/ml for tHSA), which cover the range of GA concentration in healthy plasma, which is 0.21-1.65 mg/ml (0.6%-3%). In determining the unknown GA concentrations in two commercial human plasma samples, the relative percentage difference between the values found by a standard ELISA kit and those found by our developed devices was 2.62% and 8.80%, which are within an acceptable range. The measurements of GA and tHSA were completed within 20 min for the total sample-to-answer diagnosis, fulfilling the demand for rapid analysis. Furthermore, the recovery values ranged from 99.4% to 110% in device accuracy tests. These results indicate that the developed paper based device with boronic acid-derived agarose beads is a promising platform for GA and tHSA detection as applied to self-monitoring systems. PMID- 29464010 TI - Separation of cancer cells using vortical microfluidic flows. AB - Label-free separation of viable cancer cells using vortical microfluidic flows has been introduced as a feasible cell collection method in oncological studies. Besides the clinical importance, the physics of particle interactions with the vortex that forms in a wall-confined geometry of a microchannel is a relatively new area of fluid dynamics. In our previous work [Haddadi and Di Carlo, J. Fluid. Mech. 811, 436-467 (2017)], we have introduced distinct aspects of inertial flow of dilute suspensions over cavities in a microchannel such as breakdown of the separatrix and formation of stable limit cycle orbits for finite size polystyrene particles. In this work, we extend our experiments to address the engineering physics of cancer cell entrapment in microfluidic cavities. We begin by studying the effects of the channel width and device height on the morphology of the vortex, which has not been discussed in our previous work. The stable limit cycle orbits of finite size cancer cells are then presented. We demonstrate effects of the separatrix breakdown and the limit cycle formation on the operation of the cancer cell separation platform. By studying the flow of dilute cell suspensions over the cavities, we further develop the notion of the cavity capacity and the relative rate of cell accumulation as optimization criteria which connect the device geometry with the flow. Finally, we discuss the proper placement of multiple cavities inside a microchannel for improved cell entrapment. PMID- 29464011 TI - A microfluidic device to study electrotaxis and dopaminergic system of zebrafish larvae. AB - The zebrafish is a lower vertebrate model organism offering multiple applications for both fundamental and biomedical research into the nervous system from genes to behaviour. Investigation of zebrafish larvae's movement in response to various stimuli, which involves the dopaminergic system, is of interest in the field of sensory-motor integration. Nevertheless, the conventional methods of movement screening in Petri dishes and multi-well plates are mostly qualitative, uncontrollable, and inaccurate in terms of stimulus delivery and response analysis. We recently presented a microfluidic device built as a versatile platform for fluid flow stimulation and high speed time-lapse imaging of rheotaxis behaviour of zebrafish larvae. Here, we describe for the first time that this microfluidic device can also be used to test zebrafish larvae's sense of the electric field and electrotaxis in a systemic manner. We further show that electrotaxis is correlated with the dopamine signalling pathway in a time of day dependent manner and by selectively involving the D2-like dopamine receptors. The primary outcomes of this research opens avenues to study the molecular and physiological basis of electrotaxis, the effects of known agonist and antagonist compounds on the dopaminergic system, and the screen of novel pharmacological tools in the context of neurodegenerative disorders. We propose that this microfluidic device has broad application potential, including the investigation of complex stimuli, biological pathways, behaviors, and brain disorders.

PMID- 29464014 TI - Librarians against scientists: Oncotarget's lesson. PMID- 29464015 TI - Anti-miR-17 therapy delays tumorigenesis in MYC-driven hepatocellular carcinoma (HCC). AB - Hepatocellular carcinoma (HCC) remains a significant clinical challenge with few therapeutic options. Genomic amplification and/or overexpression of the MYC oncogene is a common molecular event in HCC, thus making it an attractive target for drug therapy. Unfortunately, currently there are no direct drug therapies against MYC. As an alternative strategy, microRNAs regulated by MYC may be downstream targets for therapeutic blockade. MiR-17 family is a microRNA family transcriptionally regulated by MYC and it is commonly overexpressed in human HCCs. In this study, we performed systemic delivery of a novel lipid nanoparticle (LNP) encapsulating an anti-miR-17 oligonucleotide in a conditional transgenic mouse model of MYC driven HCC. Treatment with anti-miR-17 in vivo, but not with a control anti-miRNA, resulted in significant de-repression of direct targets of miR-17, robust apoptosis, decreased proliferation and led to delayed tumorigenesis in MYC-driven HCCs. Global gene expression profiling revealed engagement of miR-17 target genes and inhibition of key transcriptional programs of MYC, including cell cycle progression and proliferation. Hence, anti-miR-17 is an effective therapy for MYC-driven HCC. PMID- 29464016 TI - Inhibition of the NEDD8 conjugation pathway induces calcium-dependent compensatory activation of the pro-survival MEK/ERK pathway in acute lymphoblastic leukemia. AB - De novo and acquired drug resistance and subsequent relapse remain major challenges in acute lymphoblastic leukemia (ALL). We previously identified that pevonedistat (TAK-924, MLN4924), a first-in-class inhibitor of NEDD8 activating enzyme (NAE), elicits ER stress and has potent in vitro and in vivo efficacy against ALL. However, in pevonedistat-treated ALL cell lines, we found consistent activation of the pro-survival MEK/ERK pathway, which has been associated with relapse and poor outcome in ALL. We uncovered that inhibition of the MEK/ERK pathway in vitro and in vivo sensitized ALL cells to pevonedistat. The observed synergistic apoptotic effect appears to be mediated by inhibition of the MEK/ERK pro-survival cascade leading to de-repression of the pro-apoptotic BIM protein. Mechanistically, Ca2+ influx via the Ca2+-release-activated Ca2+ (CRAC) channel induced protein kinase C beta2 (PKC-beta2) was responsible for activation of the MEK/ERK pathway in pevonedistat-treated ALL cells. Sequestration of Ca2+ using BAPTA-AM or blockage of store-operated Ca2+ entry (SOCE) using BTP-2 both attenuated the compensatory activation of MEK/ERK signaling in pevonedistat treated ALL cells. Pevonedistat significantly altered the expression of Orai1 and stromal interaction molecule 1 (STIM1), resulting in significantly decreased STIM1 protein levels relative to Orai1. Further, we identified eIF2alpha as an important post-transcriptional regulator of STIM1, suggesting that pevonedistat induced eIF2alpha de-phosphorylation selectively down-regulates translation of STIM1 mRNA. Consequently, our data suggest that pevonedistat potentially activates SOCE and promotes Ca2+ influx leading to activation of the MEK/ERK pathway by altering the stoichiometric Orai1:STIM1 ratio and inducing ER stress in ALL cells. PMID- 29464017 TI - Regulation of E-cadherin localization by microtubule targeting agents: rapid promotion of cortical E-cadherin through p130Cas/Src inhibition by eribulin. AB - Microtubule targeting agents (MTAs) are some of the most effective anticancer drugs used to treat a wide variety of adult and pediatric cancers. Building evidence suggests that these drugs inhibit interphase signaling events and that this contributes to their anticancer actions. The effects of diverse MTAs were evaluated following a 2 hour incubation with clinically relevant concentrations to test the hypothesis that these drugs rapidly and differentially disrupt epithelial-to-mesenchymal transition (EMT)-related signaling. The MTAs rapidly promoted the cortical localization of internal pools of E-cadherin in HCC1937 breast cancer cells, with the most robust effects observed with the microtubule destabilizers eribulin and vinorelbine. Cortical E-cadherin localization was also promoted by the Src kinase inhibitor dasatinib or by siRNA-mediated depletion of the p130Cas scaffold. Mechanistic studies demonstrate that eribulin disrupts the interaction between p130Cas and Src, leading to decreased cortical Src phosphorylation that precedes the accumulation of cortical E-cadherin. These results suggest that microtubules can be actively co-opted by cancer cells to inhibit cortical E-cadherin localization, a hallmark of EMT, and provide a direct link between the initial disruption of the microtubule network and reversal of EMT phenotypes demonstrated by eribulin in long-term studies. PMID- 29464018 TI - Ganglioside GM1 contributes to extracellular/intracellular regulation of insulin resistance, impairment of insulin signaling and down-stream eNOS activation, in human aortic endothelial cells after short- or long-term exposure to TNFalpha. AB - Vascular insulin resistance induced by inflammatory cytokines leads to the initiation and development of vascular diseases. In humans, circulating TNFalpha levels are increased during aging, suggesting a correlation between vascular insulin resistance and plasma TNFalpha levels. Currently, the precise molecular mechanisms of vascular insulin resistance mediated by TNFalpha are not well characterized. We aimed at clarifying whether glycosphingolipids contribute to vascular insulin resistance after inflammatory stimulation. In this study, we examined vascular insulin resistance using human aortic endothelial cells after treatment with different concentrations of TNFalpha for different time intervals for mimicking in vivo acute or chronic inflammatory situations. We show that ganglioside GM1 levels on cell membranes change depending on time of exposure to TNFalpha and its concentration and that the GM1 expression is associated with specific extracellular/intracellular regulation of the insulin signaling cascade. Furthermore, we provide evidence that factors such as aging and senescence affect the regulation of insulin resistance. Our data suggest that GM1 is a key player in the induction of vascular insulin resistance after short- or long-term exposure to TNFalpha and is a good extracellular target for prevention and cure of vascular diseases. PMID- 29464019 TI - The involvement of serum exosomal miR-500-3p and miR-770-3p in aging: modulation by calorie restriction. AB - Recent studies have shown a role for miRNAs in aging and age-related diseases, and the modulation of miRNA expression by diet attracts attention as a new therapeutic strategy. Here, we focused on identifying specific exosomal miRNAs derived from serum of aged rats and the effect of short-term calorie restriction (CR) on their expression. Exosomes from serum of young (7-month), old (22-month), and old-CR Sprague Dawley rats were isolated and characterized by transmission electron microscopy analyses, dynamic light scattering measurements, and Western blotting. A total of 12 significantly expressed miRNAs in serum exosomes of young and old rats were identified by next generation sequencing. After analysis of qRT PCR, we found that miR-500-3p and miR-770-3p expression was significantly upregulated by aging and downregulated by CR. Furthermore, receiver operating characteristic (ROC) curve revealed that the selected miRNAs represented high accuracy in discriminating old rats from young rats. Finally, PANTHER analysis predicted selected miRNAs targets genes involved in Wnt/chemokines and cytokines related inflammatory signaling pathway and function as transcription factor. In conclusion, our results suggest that the expression of serum exosomal miR-500-3p and miR-770-3p was significantly increased with aging, whereas these were decreased by CR, and age-/CR-modulated exosomal miR-500-3p and miR-770-3p could potentially be used as informative biomarkers candidates for aging. PMID- 29464020 TI - MMP2-A2M interaction increases ECM accumulation in aged rat kidney and its modulation by calorie restriction. AB - Age-associated renal fibrosis is related with renal function decline during aging. Imbalance between accumulation and degradation of extracellular matrix is key feature of fibrosis. In this study, RNA-sequencing (RNA-Seq) results based on next-generation sequencing (NGS) data were analyzed to identify key proteins that change during aging and calorie restriction (CR). Among the changed genes, A2M and MMP2, which are known to interact, exhibited the highest between centrality (BC) and degree values when analyzed by protein-protein interaction (PPI). Both mRNA and protein levels of MMP2 and A2M were increased during aging. Furthermore, the interaction between MMP2 and A2M was verified by immunoprecipitation and immunohistochemistry. MMP2 activity was further measured under the presence or absence of A2M-MMP2 interaction. MMP2 activity, which was increased under the absence of A2M-MMP2 interaction, was significantly decreased under the presence of interactions in aged kidney. We further hypothesized that the interaction between A2M-MMP2 played a role in the inactivation of MMP2 leading to accumulation of ECM including collagen type I and IV. Aged kidney showed highly accumulated MMP2 substrate proteins despite of increased MMP2 protein expression and CR blunted these accumulation. Additional in vivo analysis revealed that the signal transducer and activator of transcription (STAT) 3 transcriptional factor was significantly increased thus increasing A2M expression during aging. STAT3 activating cytokines were also highly increased in aged kidney. In conclusion, the results of the present study indicate that A2M-MMP2 interaction has a role in age-associated renal ECM accumulation and in the suppression such fibrosis by CR. PMID- 29464021 TI - Association of serum levels of antibodies against MMP1, CBX1, and CBX5 with transient ischemic attack and cerebral infarction. AB - Transient ischemic attack (TIA) is a predictor for cerebral infarction (CI), and early diagnosis of TIA is extremely important for the prevention of CI. We set out to identify novel antibody biomarkers for TIA and CI, and detected matrix metalloproteinase 1 (MMP1), chromobox homolog 1 (CBX1), and chromobox homolog 5 (CBX5) as candidate antigens using serological identification of antigens by recombinant cDNA expression cloning (SEREX) and Western blotting to confirm the presence of serum antibodies against the antigens. Amplified luminescent proximity homogeneous assay-linked immunosorbent assay (AlphaLISA) revealed that serum antibody levels were significantly higher in patients with TIA or acute phase CI (aCI) compared with healthy donors (P < 0.01). Spearman's correlation analysis and multivariate logistic regression analysis demonstrated that levels of anti-MMP1, anti-CBX1, and anti-CBX5 antibodies were associated with age, cigarette-smoking habits, and blood pressure. Thus, serum levels of antibodies against MMP1, CBX1, and CBX5 could potentially serve as useful tools for diagnosing TIA and predicting the onset of aCI. PMID- 29464022 TI - Anticoagulants inhibit proteolytic clearance of plasma amyloid beta. AB - We recently discovered a plasma proteolysis pathway, termed the FXII-FVII pathway which is composed of coagulation proteases, and found it to be mainly responsible for the clearance of Abeta42 in the plasma in mice. Abeta42 and Abeta40 are the main Abeta forms in Alzheimer's disease (AD). In the present study, in vitro assays, wild type (WT) mice and J20 mice (a transgenic AD model) are used to assess the degradation of Abeta40 and Abeta42 by the FXII-FVII pathway and the impact of anticoagulants on such degradation. Four clinically available and mechanistically distinct anticoagulants are evaluated, including dabigatran, enoxaparin (EP), rivaroxaban and warfarin. Each anticoagulant significantly elevates plasma level of synthetic Abeta42 in WT mice, among which EP is the most effective. The differential efficacies of the anticoagulants in elevating plasma Abeta42 level match closely with their inhibitory mechanisms towards the FXII FVII pathway. Plasma Abeta40 is also degraded by the FXII-FVII pathway and is protected by EP. Moreover, the FXII-FVII pathway is significantly activated in J20 mice, but EP inhibits the activation and significantly elevates plasma levels of both Abeta40 and Abeta42. Taken together, our results shed new light on Abeta metabolism, reveal a novel function of anticoagulants, and suggest a novel approach to potentially developing plasma Abeta as an AD biomarker. PMID- 29464023 TI - Interferon sensitivity-determining region of hepatitis C virus influences virus production and interferon signaling. AB - The number of amino acid substitutions in the interferon (IFN) sensitivity determining region (ISDR) of hepatitis C virus (HCV) NS5A is a strong predictor for the outcome of IFN-based treatment. To assess the involvement of ISDR in the HCV life cycle and to clarify the molecular mechanisms influencing IFN susceptibility, we used recombinant JFH-1 viruses with NS5A of the genotype 1b Con1 strain (JFH1/5ACon1) and with NS5A ISDR containing 7 amino acid substitutions (JFH1/5ACon1/i-7mut), and compared the virus propagation and the induction of interferon-stimulated genes (ISGs). By transfecting RNAs of these strains into HuH-7-derived cells, we found that the efficiency of infectious virus production of JFH1/5ACon1/i-7mut was attenuated compared with JFH1/5ACon1. After transfecting full-length HCV RNA into HepaRG cells, the mRNA expression of ISGs was sufficiently induced by IFN treatment in JFH1/5ACon1/i-7mut-transfected but not in JFH1/5ACon1-transfected cells. These data suggested that the NS5A mediated inhibition of ISG induction was deteriorated by amino acid substitutions in the ISDR. In conclusion, using recombinant JFH-1 viruses, we demonstrated that HCV NS5A is associated with infectious virus production and the inhibition of IFN signaling, and amino acid substitutions in the NS5A ISDR deteriorate these functions. These observations explain the strain-specific evasion of IFN signaling by HCV. PMID- 29464024 TI - NAB2 is a novel immune stimulator of MDA-5 that promotes a strong type I interferon response. AB - Novel adjuvants are needed to increase the efficacy of vaccine formulations and immune therapies for cancer and chronic infections. In particular, adjuvants that promote a strong type I IFN response are required, since this cytokine is crucial for the development of efficient anti-tumoral and anti-viral immunity. Nucleic acid band 2 (NAB2) is a double-stranded RNA molecule isolated from yeast and identified as an agonist of the pattern-recognition receptors TLR3 and MDA-5. We compared the ability of NAB2 to activate innate immunity with that of poly(I:C), a well-characterized TLR3 and MDA-5 agonist known for the induction of type I IFN. NAB2 promoted stronger IFN-alpha production and induced a higher activation state of both murine and human innate immune cells compared to poly(I:C). This correlated with a stronger activation of the signalling pathway downstream of MDA 5, and IFN-alpha induction was dependent on MDA-5. Upon injection, NAB2 induced higher levels of serum IFN-alpha in mice than poly(I:C). These results suggest that NAB2 has the potential to become an efficient adjuvant for the induction of type-I IFN responses in therapeutic immunization against cancer or infections. PMID- 29464025 TI - Microsatellite instability is a biomarker for immune checkpoint inhibitors in endometrial cancer. AB - In recent years, it has become evident that tumor cells have immune escape mechanisms, and immune checkpoint inhibitor therapy (anti-PD-1/PD-L1 antibody) has shown benefit in various cancers. In endometrial tumors with microsatellite instability (MSI), somatic mutations have the potential to encode ''non-self'' immunogenic antigens, and lymphocytes have been shown to infiltrate the tumor. Therefore, immune checkpoint inhibitor therapy might be effective in endometrial cancers with MSI. Expression of mismatch repair (MMR) proteins (MLH1, PMS2, MSH2, and MSH6), the presence of tumor-infiltrating lymphocytes (CD8+), and PD-1/PD-L1 expression were assessed by immunohistochemistry in 149 patients with endometrial cancer. We examined whether tumors with MSI had an enhanced immune microenvironment and whether MSI could be a predictor of the therapeutic effect of PD-1/PD-L1 immunotherapy in endometrial cancer. Loss of MMR protein expression was identified in 42 (28.2%) of 149 patients (MSI group) with endometrial cancer. There was no significant relationship between MSI status and age (p = 0.193), histological grade (p = 0.097), FIGO stage (p = 0.508), pelvic lymph node metastasis (p = 0.139), or depth of myometrial invasion (p = 0.494). However, the presence of tumor-infiltrating lymphocytes (CD8+) and PD-L1/PD-1 expression were significantly higher in the MSI group compared to the microsatellite-stable group (p = 0.002, p = 0.001, and p = 0.008, respectively). These results suggest that immune checkpoint inhibitors (anti-PD-1/PD-L1 antibody) could be effective in endometrial cancers with MSI. The presence of MSI may be a biomarker for good response to PD-1/PD-L1 immunotherapy in endometrial cancer. PMID- 29464027 TI - Combining molecular and immunohistochemical analyses of key drivers in primary melanomas: interplay between germline and somatic variations. AB - Due to the high mutational somatic burden of Cutaneous Malignant Melanoma (CMM) a thorough profiling of the driver mutations and their interplay is necessary to explain the timing of tumorigenesis or for the identification of actionable genetic events. The aim of this study was to establish the mutation rate of some of the key drivers in melanoma tumorigenesis combining molecular analyses and/or immunohistochemistry in 93 primary CMMs from an Italian cohort also characterized for germline status, and to investigate an interplay between germline and somatic variants. BRAF mutations were present in 68% of cases, while CDKN2A germline mutations were found in 16 % and p16 loss in tissue was found in 63%. TERT promoter somatic mutations were detected in 38% of cases while the TERT -245T>C polymorphism was found in 51% of cases. NRAS mutations were found in 39% of BRAF negative or undetermined cases. NF1 was expressed in all cases analysed. MC1R variations were both considered as a dichotomous variable or scored. While a positive, although not significant association between CDKN2A germline mutations, but not MC1R variants, and BRAF somatic mutation was found, we did not observe other associations between germline and somatic events. A yet undescribed inverse correlation between TERT -245T>C polymorphism and the presence of BRAF mutation was found. It is possible to hypothesize that -245T>C polymorphism could be included in those genotypes which may influence the occurrence of BRAF mutations. Further studies are needed to investigate the role of -245T>C polymorphism as a germline predictor of BRAF somatic mutation status.

The novel deep learning and transfer learning techniques are turning any data about the person into medical data transforming simple facial pictures and videos into powerful sources of data for predictive analytics. Presently, the patients do not have control over the access privileges to their medical records and remain unaware of the true value of the data they have. In this paper, we provide an overview of the next-generation artificial intelligence and blockchain technologies and present innovative solutions that may be used to accelerate the biomedical research and enable patients with new tools to control and profit from their personal data as well with the incentives to undergo constant health monitoring. We introduce new concepts to appraise and evaluate personal records, including the combination-, time- and relationship-value of the data. We also present a roadmap for a blockchain-enabled decentralized personal health data ecosystem to enable novel approaches for drug discovery, biomarker development, and preventative healthcare. A secure and transparent distributed personal data marketplace utilizing blockchain and deep learning technologies may be able to resolve the challenges faced by the regulators and return the control over personal data including medical records back to the individuals.

AB - Co-occurrence of Flt3ITD and TET2 mutations provoke an animal model of AML by epigenetic repression of Wnt pathway antagonists, including RUNX3, and by hyperexpression of ID1, encoding Wnt agonist. These affect HOXA over-expression and treatment resistance. A comparable epigenetic phenotype was identified among adult AML patients needing novel intervention. We chose combinations of targeted agents acting on distinct effectors, at the levels of both signal transduction and chromatin remodeling, in relapsed/refractory AML's, including Flt3ITD+ve, described with a signature of repressed tumor suppressor genes, involving Wnt antagonist RUNX3, occurring along with ID1 and HOXA over-expressions. We tracked patient response to combination of Flt3/Raf inhibitor, Sorafenib, and Vorinostat, pan-histone deacetylase inhibitor, without or with added Bortezomib, in consecutive phase I trials. A striking association of rapid objective remissions (near-complete, complete responses) was noted to accompany induced early pharmacodynamic changes within patient blasts in situ, involving these effectors, significantly linking RUNX3/Wnt antagonist de-repression (80%) and ID1 downregulation (85%), to a response, also preceded by profound HOXA9 repression. Response occurred in context of concurrent TET2 mutation/hypomorphy and Flt3ITD+ve mutation (83% of complete responses). Addition of Bortezomib to the combination was vital to attainment of complete response in Flt3ITD+ve cases exhibiting such Wnt pathway dysregulation. PMID- 29464029 TI - The protein kinase SIK downregulates the polarity protein Par3. AB - The multifunctional cytokine transforming growth factor beta (TGFbeta) controls homeostasis and disease during embryonic and adult life. TGFbeta alters epithelial cell differentiation by inducing epithelial-mesenchymal transition (EMT), which involves downregulation of several cell-cell junctional constituents. Little is understood about the mechanism of tight junction disassembly by TGFbeta. We found that one of the newly identified gene targets of TGFbeta, encoding the serine/threonine kinase salt-inducible kinase 1 (SIK), controls tight junction dynamics. We provide bioinformatic and biochemical evidence that SIK can potentially phosphorylate the polarity complex protein Par3, an established regulator of tight junction assembly. SIK associates with Par3, and induces degradation of Par3 that can be prevented by proteasomal and lysosomal inhibition or by mutation of Ser885, a putative phosphorylation site on Par3. Functionally, this mechanism impacts on tight junction downregulation. Furthermore, SIK contributes to the loss of epithelial polarity and examination of advanced and invasive human cancers of diverse origin displayed high levels of SIK expression and a corresponding low expression of Par3 protein. High SIK mRNA expression also correlates with lower chance for survival in various carcinomas. In specific human breast cancer samples, aneuploidy of tumor cells best correlated with cytoplasmic SIK distribution, and SIK expression correlated with TGFbeta/Smad signaling activity and low or undetectable expression of Par3. Our model suggests that SIK can act directly on the polarity protein Par3 to regulate tight junction assembly. PMID- 29464030 TI - Under-expression of CK2beta subunit in ccRCC represents a complementary biomarker of p-STAT3 Ser727 that correlates with patient survival. AB - Clear cell renal cell carcinoma (ccRCC) is the most common and aggressive subtype of renal cancer. STAT3 pathway is altered in these tumors and p-STAT3 Ser727 is an independent prognostic factor for ccRCC. Protein kinase CK2 is altered in different types of tumors and overexpression of CK2alpha is considered predictive of bad prognosis and metastatic risk. CK2 subunits analyses in ccRCC samples showed increased CK2alpha/alpha' nuclear content in all cases, but decreased cytosolic CK2beta (CK2betacyt) levels in the more advanced tumors. Stable downregulation of CK2beta in renal proximal tubular (HK-2) and clear cell adenocarcinoma (786-O) cells triggered changes in E-cadherin, vimentin and Snail1 protein levels indicative of epithelial-to-mesenchymal transition (EMT), and increased HIF-alpha. Moreover, CK2beta was required in order to observe STAT3 Ser727 phosphorylation in HK-2 but not in 786-O cells. We also observed that CK2beta improved the prognostic value of p-STAT3 Ser727, as CK2betacyt>41 (median value) discriminates patients free of disease for a period of 10 years upon surgery, from those with CK2betacyt<41, when p-STAT3 Ser727levels are low. We conclude that CK2beta down-regulation might represent a mechanism to support EMT and angiogenesis and that CK2betacyt levels are instrumental to refine prognosis of ccRCC patients with low p-STAT3 Ser727 levels. PMID- 29464031 TI - Phospholipase Cgamma1 links inflammation and tumorigenesis in colitis-associated cancer. AB - : Colorectal cancer (CRC) is the third diagnosed cancer and the second leading cause of cancer-related deaths in the United States. Colorectal cancer is linked to inflammation and phospholipase Cgamma1 (PLCgamma1) is associated with tumorigenesis and the development of colorectal cancer; however, evidence of mechanisms connecting them remains unclear. The tight junctions (TJ), as intercellular junctional complexes, have an important role for integrity of the epithelial barrier to regulate the cellular permeability. Here we found that PLCgamma1 regulated colitis and tumorigenesis in intestinal epithelial cells (IEC). To induce the colitis-associated cancer (CAC), we used the AOM/DSS model. Mice were sacrificed at 100 days (DSS three cycles) and 120 days (DSS one cycle). In a CAC model, we showed that the deletion of PLCgamma1 in IEC decreased the incidence of tumors by enhancing apoptosis and inhibiting proliferation during tumor development. Accordingly, the deletion of PLCgamma1 in IEC reduced colitis induced epithelial inflammation via inhibition of pro-inflammatory cytokines and mediators. The PLCgamma1 pathway in IEC accelerated colitis-induced epithelial damage via regulation of TJ proteins. CONCLUSIONS: Our findings suggest that PLCgamma1 is a critical regulator of colitis and colorectal cancer and could further help in the development of therapy for colitis-associated cancer. PMID- 29464032 TI - Stroma-derived extracellular vesicles deliver tumor-suppressive miRNAs to pancreatic cancer cells. AB - The biology of tumor-associated stroma (TAS) in pancreatic ductal adenocarcinoma (PDAC) is not well understood. The paradoxical observation that stroma-depletion strategies lead to progression of PDAC reinforced the need to critically evaluate the functional contribution of TAS in the initiation and progression of PDAC. PDAC and TAS cells are unique in their expression of specific miRNAs, and this specific miRNA expression pattern alters host to tumor microenvironment interactions. Using primary human pancreatic TAS cells and primary xenograft PDAC cells co-culture, we provide evidence of miRNA trafficking and exchanging between TAS and PDAC cells, in a two-way, cell-contact independent fashion, via extracellular vesicles (EVs) transportation. Selective packaging of miRNAs into EVs led to enrichment of stromal specific miR-145 in EVs secreted by TAS cells. Exosomes, but not microvesicles, derived from human TAS cells demonstrated a tumor suppressive role by inducing PDAC cell apoptosis. This effect was mitigated by anti-miR-145 sequences. Our data suggest that TAS-derived miRNAs are delivered to adjacent PDAC cells via exosomes and suppress tumor cell growth. These data highlight that TAS cells secrete exosomes carrying tumor suppressive genetic materials, a possible anti-tumor capacity. Future work of the development of patient-derived exosomes could have therapeutic implications for unresectable PDAC. PMID- 29464033 TI - Long-term prediction of prostate cancer diagnosis and death using PSA and obesity related anthropometrics at early middle age: data from the malmo preventive project. AB - Objectives: To evaluate whether anthropometric parameters add to PSA measurements in middle-aged men for risk assessment of prostate cancer (PCa) diagnosis and death. Results: After adjusting for PSA, both BMI and weight were significantly associated with an increased risk of PCa death with the odds of a death corresponding to a 10 kg/m2 or 10 kg increase being 1.58 (95% CI 1.10, 2.28; p = 0.013) and 1.14 (95% CI 1.02, 1.26; p = 0.016) times greater, respectively. AUCs did not meaningfully increase with the addition of weight or BMI to prediction models including PSA. Materials and Methods: In 1974 to 1986, 22,444 Swedish men aged 44 to 50 enrolled in Malmo Preventive Project, Sweden, and provided blood samples and anthropometric data. Rates of PSA screening in the cohort were very low. Documentation of PCa diagnosis and disease-specific death up to 2014 was retrieved through national registries. Among men with anthropometric measurements available at baseline, a total of 1692 men diagnosed with PCa were matched to 4190 controls, and 464 men who died of disease were matched to 1390 controls. Multivariable conditional logistic regression was used to determine whether diagnosis or death from PCa were associated with weight and body mass index (BMI) at adulthood after adjusting for PSA. Conclusions: Men with higher BMI and weight at early middle age have an increased risk of PCa diagnosis and death after adjusting for PSA. However, in a multi-variable numerical statistical model, BMI and weight do not importantly improve the predictive accuracy of PSA. Risk stratification of screening should be based on PSA without reference to anthropometrics. PMID- 29464034 TI - Analysis of the circular RNA transcriptome in endometrial cancer. AB - Circular RNAs (circRNAs) are a naturally occurring family of non-coding RNA that may regulate gene expression in mammals. circRNAs are more stable than messenger RNAs due to their resistance to RNA exonuclease. A growing body of evidence has shown that the expression of circRNAs is regulated during development in a tissue specific manner. CircRNAs have been implicated in a number of cancers; however, their role in endometrial cancer (EC) is completely unknown. Here, we report the circular transcriptome specific for EC as determined by RNA sequencing. We found that the overall abundance of circRNAs is lower in EC than in normal endometrium. Further, there are numerous 'hotspot' genes from which circRNAs are transcribed that may account for alterations in circRNA expression between the normal and malignant endometrium. Most importantly, we have also identified circRNAs that are differentially expressed between malignant and normal endometrial tissue. The functional significance of these circRNAs in cancer remains to be determined, but they may serve as potential biomarkers for the diagnosis of EC or monitoring of EC progression. PMID- 29464035 TI - Upregulation of cell cycle genes in head and neck cancer patients may be antagonized by erufosine's down regulation of cell cycle processes in OSCC cells. AB - The TCGA database was analyzed to identify deregulation of cell cycle genes across 24 cancer types and ensuing effects on patient survival. Pan-cancer analysis showed that head and neck squamous cell carcinoma (HNSCC) ranks amongst the top four cancers showing deregulated cell cycle genes. Also, the median gene expression of all CDKs and cyclins in HNSCC patient samples was higher than that of the global gene expression. This was verified by IHC staining of CCND1 from HNSCC patients. When evaluating the quartiles with highest and lowest expression, increased CCND1/CDK6 levels had negative implication on patient survival. In search for a drug, which may antagonize this tumor profile, the potential of the alkylphosphocholine erufosine was evaluated against cell lines of the HNSCC subtype, oral squamous cell carcinoma (OSCC) using in-vitro and in-vivo assays. Erufosine inhibited growth of OSCC cell lines concentration dependently. Initial microarray findings revealed that cyclins and CDKs were down-regulated concentration dependently upon exposure to erufosine and participated in negative enrichment of cell cycle processes. These findings, indicating a pan-cdk/cyclin inhibition by erufosine, were verified at both, mRNA and protein levels. Erufosine caused a G2/M block and inhibition of colony formation. Significant tumor growth retardation was seen upon treatment with erufosine in a xenograft model. For the decreased cyclin D1 and CDK 4/6 levels found in tumor tissue, these proteins can serve as biomarker for erufosine intervention. The findings demonstrate the potential of erufosine as cell cycle inhibitor in HNSCC treatment, alone or in combination with current therapeutic agents. PMID- 29464036 TI - Breast cancer stem cells in HER2-negative breast cancer cells contribute to HER2 mediated radioresistance and molecular subtype conversion: clinical implications for serum HER2 in recurrent HER2-negative breast cancer. AB - Although it has been proposed that the beneficial effect of HER2-targeted therapy in HER2-negative breast cancer is associated with the molecular subtype conversion, the underlying mechanism and the clinical biomarkers are unclear. Our study showed that breast cancer stem cells (BCSCs) mediated HER2 subtype conversion and radioresistance in HER2-negative breast cancer cells and evaluated serum HER2 as a clinical biomarker for HER2 subtype conversion. We found that the CD44+/CD24-/low BCSCs from HER2-negative breast cancer MCF7 cells overexpressed HER2 and EGFR and showed the radioresistant phenotype. In addition, we showed that trastuzumab treatment sensitized the radioresistant phenotype of the CD44+/CD24-/low cells with decreased levels of HER2 and EGFR, which suggested that HER2-targeted therapy in HER2-negative breast cancer could be useful for targeting BCSCs that overexpress HER2/EGFR. Importantly, our clinical data showed that serial serum HER2 measurement synchronously reflected the disease relapse and the change in tumor burden in some patients who were initially diagnosed as HER2-negative breast cancer, which indicated that serum HER2 could be a clinical biomarker for the evaluation of HER2 subtype conversion in patients with recurrent HER2-negative breast cancer. Therefore, our data have provided in vitro and in vivo evidence for the molecular subtype conversion of HER2-negative breast cancer. PMID- 29464037 TI - Comparison of the modified low-dose cytarabine and etoposide with decitabine therapy for elderly acute myeloid leukemia patients unfit for intensive chemotherapy. AB - To overcome unsatisfactory results of classical low-dose cytarabine (LDAC) of cytarabine <=20 mg twice daily (BID) subcutaneously for 10 days for patients with elderly acute myeloid leukemia (eAML), we evaluated a modified LDAC (mLDAC) of cytarabine 20 mg/m2 BID subcutaneously plus etoposide 50 mg BID orally for 14 days. To determine its feasibility, we compared outcomes of 77 and 42 eAML patients who received, respectively, mLDAC and decitabine (DAC; 20 mg/m2 intravenously daily for 5 days), which has shown better outcomes compared to those of classical LDAC. Most of baseline characteristics of two groups were well balanced. The mLDAC group had a higher complete response (CR) rate compared to the DAC group (46.8% vs. 19.0%, P < 0.01). Unlike the classical LDAC, mLDAC induced CR in patients with adverse cytogenetics, with its rate similar to that of the DAC group (33.3% vs. 20.0%; P = 0.58). Meanwhile, mucositis, neutropenic fever and invasive aspergillosis were more frequently observed in the mLDAC group, with no difference in early mortality between two groups (P > 0.05). The median overall survival rates of the mLDAC and DAC groups were comparable (8.7 vs 8.3 months, respectively, P = 0.35), presumably because the advantage of higher CR rate in the mLDAC group was offset by beneficial effects of marrow response, which is observed dominantly in the DAC group. Our results suggested that the outcomes of classical LDAC could be improved by modest modifications, to be comparable to those of DAC. PMID- 29464038 TI - The influence of chemotherapy on adenosine-producing B cells in patients with head and neck squamous cell carcinoma. AB - Introduction: Head and neck squamous cell carcinoma (HNSCC) strongly suppresses the immune system, resulting in increased metastasis and recurrent disease. Chemotherapy is part of the multimodal treatment but may further immunosuppression. Recently, we demonstrated that regulatory B cells (Breg), defined as CD19+CD39+CD73+ B cells, play a significant role in the production of immunosuppressive, extracellular adenosine (ADO). Here, we tested the influence of chemotherapy on Breg function. Results: In HNSCC patients, Breg were diminished in absolute number and frequency after chemotherapy (paired samples). Chemotherapeutic drugs had variable effects; while platinum-based chemotherapy decreased the expression of CD39, methotrexate led to a functional increase in CD39 expression and increased production of immunosuppressive ADO. These findings were confirmed in a second patient cohort. Surface expression of CD39 correlated strongly with the production of ADO as measured by mass spectrometry. Conclusions: Platinum-based anti-tumor-therapy reduces the number of adenosine producing B cells and, consequently, potential immunosuppression within the tumor environment. Breg function in terms of ADO production and their potential capacity to suppress CD4+ T cells are promoted by methotrexate treatment amplifying anti-inflammatory therapeutic effects. Our results add to the understanding of how chemotherapeutic drugs can influence the human immune system and may therefore help to orchestrate standard oncologic therapy with new immune modulating approaches. Methods: Mononuclear cells were collected prospectively from HNSCC patients before and after chemotherapy (n = 18), from healthy donors (n = 20), and an additional cohort sampled several months after chemotherapy (n = 14). Frequency, phenotype, and function of Breg were determined by multicolor flow cytometry, ATP luminescence assay as well as mass spectrometry measuring 5' AMP, ADO, and inosine. Isolated B cells were incubated with chemotherapeutic drugs (cisplatin, methotrexate, paclitaxel, 5-fluorouracil) in vitro for functional studies. PMID- 29464039 TI - High RAC3 expression levels are required for induction and maintaining of cancer cell stemness. AB - RAC3 is a transcription coactivator, usually overexpressed in several tumors and required to maintain the pluripotency in normal stem cells. In this work we studied the association between RAC3 overexpression on cancer cell stemness and the capacity of this protein to induce cancer stem properties in non tumoral cells. We performed in vitro and in vivo experiments using two strategies: by overexpressing RAC3 in the non tumoral cell line HEK293 and by silencing RAC3 in the human colorectal epithelial cell line HCT116 by transfection. Furthermore, we analysed public repository microarrays data from human colorectal tumors in different developmental stages. We found that RAC3 overexpression was mainly associated to CD133+ side-population of colon cancer cells and also to early and advanced stages of colon cancer, involving increased expression of mesenchymal and stem markers. In turn, RAC3 silencing induced diminished tumoral properties and cancer stem cells as determined by Hoechst efflux, tumorspheres and clonogenic growth, which correlated with decreased Nanog and OCT4 expression. In non tumoral cells, RAC3 overexpression induced tumoral transformation; mesenchymal phenotype and stem markers expression. Moreover, these transformed cells generated tumors in vivo. Our results demonstrate that RAC3 is required for maintaining and induction of cancer cell stemness. PMID- 29464040 TI - Activation of Grm1 expression by mutated BRaf (V600E) in vitro and in vivo. AB - Our laboratory previously showed that ectopic expression of Grm1 is sufficient to induce spontaneous melanoma formation with 100% penetrance in transgenic mouse model, TG-3, which harbors wild-type BRaf. Studies identified Grm1 expression in human melanoma cell lines and primary to secondary metastatic melanoma biopsies having wild-type or mutated BRaf, but not in normal melanocytes or benign nevi. Grm1 expression was detected in tissues from mice genetically engineered with inducible melanocyte-specific BRafV600E. Additionally, stable clones derived from introduction of exogenous BRafV600E in mouse melanocytes also showed Grm1 expression, which was not detected in the parental or empty vector-derived cells, suggesting that expression of BRafV600E could activate Grm1 expression. Despite aberrant Grm1 expression in the inducible, melanocyte-specific BRafV600E mice, no tumors formed. However, in older mice, the melanocytes underwent senescence, as demonstrated previously by others. It was proposed that upregulated p15 and TGFbeta contributed to the senescence phenotype. In contrast, in older TG-3 mice the levels of p15 and TGFbeta remained the same or lower. Taken together, these results suggest the temporal regulation on the expression of "oncogenes" such as Grm1 or BRafV600E is critical in the future fate of the cells. If BRafV600E is turned on first, Grm1 expression can be induced, but this is not sufficient to result in development of melanoma; the cells undergo senescence. In contrast, if ectopic expression of Grm1 is turned on first, then regardless of wild-type or mutated BRaf in the melanocytes melanoma development is the consequence. PMID- 29464041 TI - Inhibition of NF-kappaB prevents the acidic bile-induced oncogenic mRNA phenotype, in human hypopharyngeal cells. AB - Bile-containing gastro-duodenal reflux has been clinically considered an independent risk factor in hypopharyngeal carcinogenesis. We recently showed that the chronic effect of acidic bile, at pH 4.0, selectively induces NF-kappaB activation and accelerates the transcriptional levels of genes, linked to head and neck cancer, in normal hypopharyngeal epithelial cells. Here, we hypothesize that NF-kappaB inhibition is capable of preventing the acidic bile-induced and cancer-related mRNA phenotype, in treated normal human hypopharyngeal cells. In this setting we used BAY 11-7082, a specific and well documented pharmacologic inhibitor of NF-kappaB, and we observed that BAY 11-7082 effectively inhibits the acidic bile-induced gene expression profiling of the NF-kappaB signaling pathway (down-regulation of 72 out of 84 analyzed genes). NF-kappaB inhibition significantly prevents the acidic bile-induced transcriptional activation of NF kappaB transcriptional factors, RELA (p65) and c-REL, as well as genes related to and commonly found in established HNSCC cell lines. These include anti-apoptotic bcl-2, oncogenic STAT3, EGFR, ?Np63, TNF-alpha and WNT5A, as well as cytokines IL 1beta and IL-6. Our findings are consistent with our hypothesis demonstrating that NF-kappaB inhibition effectively prevents the acidic bile-induced cancer related mRNA phenotype in normal human hypopharyngeal epithelial cells supporting an understanding that NF-kappaB may be a critical link between acidic bile and early preneoplastic events in this setting. PMID- 29464042 TI - YAP-associated chromosomal instability and cholangiocarcinoma in mice. AB - Deregulated Hippo pathway signaling is associated with aberrant activation of the downstream effector yes-associated protein (YAP), an emerging key oncogenic mediator in cholangiocarcinoma (CCA). In our prior work, we have demonstrated that biliary transduction of YAP along with Akt as a permissive factor induces CCA in mice. To further delineate the mechanisms associated with YAP-associated biliary oncogenesis, we have established seven malignant murine cell lines from our YAP-driven murine CCA model. These cells express the CCA markers SRY (Sex Determining Region Y)-Box 9 (SOX9), cytokeratin (CK)-7 and 19 but lack hepatocyte nuclear factor 4 alpha and alpha-smooth muscle actin, markers of hepatocellular carcinoma and cancer-associated fibroblasts, respectively. Notably, the murine CCA cells can be readily implanted into mouse livers with resultant orthotopic tumor formation. In this unique syngeneic orthotopic murine model, tumors exhibit histopathologic features resembling human CCA. We analyzed transcriptome data from YAP-associated parent CCA tumor nodules and identified a gene expression pattern associated with chromosomal instability, known as CIN25. Similarly, mate pair sequencing of the murine CCA cells revealed chromosomal missegregation with gains and losses of several whole chromosomes demonstrating aneuploidy. Of the CIN25 genes, forkhead box M1 (Foxm1), a key cell cycle regulator, was the most significantly upregulated CIN25 gene product. Accordingly, small interfering RNA (siRNA)-mediated silencing of YAP as well as FOXM1 inhibition with thiostrepton induced CCA cell death. These preclinical data imply a role for YAP-mediated chromosomal instability in cholangiocarcinoma, and suggest FOXM1 inhibition as a therapeutic target for CCA. PMID- 29464043 TI - Zinc finger protein 598 inhibits cell survival by promoting UV-induced apoptosis. AB - UV is one of the major causes of DNA damage induced apoptosis. However, cancer cells adopt alternative mechanisms to evade UV-induced apoptosis. To identify factors that protect cancer cells from UV-induced apoptosis, we performed a genome wide short-hairpin RNA (shRNA) screen, which identified Zinc finger protein 598 (ZNF598) as a key regulator of UV-induced apoptosis. Here, we show that UV irradiation transcriptionally upregulates ZNF598 expression. Additionally, ZNF598 knockdown in cancer cells inhibited UV-induced apoptosis. In our study, we observe that ELK1 mRNA level as well as phosphorylated ELK1 levels was up regulated upon UV irradiation, which was necessary for UV irradiation induced upregulation of ZNF598. Cells expressing ELK1 shRNA were also resistant to UV-induced apoptosis, and phenocopy ZNF598 knockdown. Upon further investigation, we found that ZNF598 knockdown inhibits UV-induced apoptotic gene expression, which matches with decrease in percentage of annexin V positive cell. Similarly, ectopic expression of ZNF598 promoted apoptotic gene expression and also increased annexin V positive cells. Collectively, these results demonstrate that ZNF598 is a UV irradiation regulated gene and its loss results in resistance to UV-induced apoptosis. PMID- 29464044 TI - The transcriptional and mutational landscapes of lipid metabolism-related genes in colon cancer. AB - Metabolic alterations encountered in tumors are well recognized and considered as a hallmark of cancer. In addition to Warburg Effect, epidemiological and experimental studies support the crucial role of lipid metabolism in colorectal cancer (CRC). The overexpression of four lipid metabolism-related genes (ABCA1, ACSL1, AGPAT1 and SCD genes) has been proposed as prognostic marker of stage II CRC (ColoLipidGene signature). In order to explore in depth the transcriptomic and genomic scenarios of ABCA1, ACSL1, AGPAT1 and SCD genes, we performed a transcriptomic meta-analysis in more than one thousand CRC individuals. Additionally we analyzed their genomic coding sequence in 95 patients, to find variants that could orchestrate CRC prognosis. We found that genetic variant rs3071, located on SCD gene, defines a 9.77% of stage II CRC patients with high risk of death. Moreover, individuals with upregulation of ABCA1 and AGPAT1 expression have an increased risk of CRC recurrence, independently of tumor stage. ABCA1 emerges as one of the main contributors to signature's prognostic effect. Indeed, both high ABCA1 expression and presence of tumoral genetic variants located in ABCA1 coding region, seem to be associated with CRC risk of death. In addition the non-synonymous polymorphism rs2230808, located on ABCA1, is associated with gene expression. Patients carrying at least one copy of minor allele showed higher levels of ABCA1 expression than patients carrying homozygous major allele. This study broaden the prognostic value of ABCA1, ACSL1, AGPAT1 and SCD genes, independently of CRC tumor stage, leading to future precision medicine approaches and "omics"-guided therapies. PMID- 29464045 TI - Pathological and functional significance of Semaphorin-5A in pancreatic cancer progression and metastasis. AB - Semaphorin-5A (SEMA5A) has differential cell surface expression between normal and cancer cells and represents an attractive target for therapeutic intervention in pancreatic cancer (PC). In this study, we delineated the pathological expression and significance of SEMA5A during PC progression and metastasis. We utilized human tissue microarrays and different PC mouse models (Pdx1-cre; LSL- Kras(G12D), Pdx1-Cre; LSL-Kras(G12D); LSL-p53(R172H) and RIP1-Tag2) to analyze SEMA5A expression during PC progression. Using human patients and different mouse models, we demonstrated that SEMA5A expression was highest in liver metastases, followed by primary pancreatic tumors, and the lowest expression was found in the normal pancreas. SEMA5A expression was localized on tumor cells with no staining in the surrounding stroma. To understand the functional significance of SEMA5A, we treated PC cell lines with recombinant SEMA5A. We observed an increase in migration, chemotaxis, and scattering of PC cells. To delineate the signaling axis of SEMA5A, we generated SEMA5A receptor-Plexin-B3 knockdown in T3M-4 and CD18/HPAF PC cell lines and observed that the effect of SEMA5A treatment was absent in the Plexin-B3 knockdown counterparts of T3M-4 and CD18/HPAF cells. SEMA5A treatment leads to phosphorylation of cMET in Plexin-B3 dependent manner. Our data demonstrate that there is an increase in SEMA5A expression during PC progression and the elevation of this expression takes place at metastatic sites especially the liver in both exocrine and endocrine tumors. SEMA5A can elicit a migratory response in cells by activating cMET through the Plexin-B3 receptor. In conclusion, SEMA5A signaling represents a potential molecule for targeting metastasis in pancreatic cancer. PMID- 29464046 TI - Identification and characterization of novel enhanced cell penetrating peptides for anti-cancer cargo delivery. AB - Cell penetrating peptides (CPP) are able cross the membrane and to transport cargos, presenting a great potential in drug delivery and diagnosis. In this paper, we have identified novel natural or synthetic CPPs. We have validated their rapid and efficient time and dose-dependent penetration, the absence of toxicity, the intracellular localization and the stability to proteases degradation, one of the main bottlenecks of peptides. Moreover, we have associate a cargo (an interfering peptide blocking the association of the serine/threonine phosphatase PP2A to its inhibitor, the oncogene SET) to the new generated shuttles and showed that they new bi-functional peptides keep the original properties of the shuttle and, in addition, are able to induce apoptosis due to the properties of the cargo. The CPPs identified in this study have promising perspectives for future anti-cancer drug delivery. PMID- 29464047 TI - A dock derived compound against laminin receptor (37 LR) exhibits anti-cancer properties in a prostate cancer cell line model. AB - Laminin receptor (67 LR) is a 67 kDa protein derived from a 37 kDa precursor (37 LR). 37/67 LR is a strong clinical correlate for progression, aggression, and chemotherapeutic relapse of several cancers including breast, prostate, and colon. The ability of 37/67 LR to promote cancer cell aggressiveness is further increased by its ability to transduce physiochemical and mechanosensing signals in endothelial cells and modulate angiogenesis. Recently, it was demonstrated that 37/67 LR modulates the anti-angiogenic potential of the secreted glycoprotein pigment epithelium-derived factor (PEDF). Restoration of PEDF balance is a desirable therapeutic outcome, and we sought to identify a small molecule that could recapitulate known signaling properties of PEDF but without the additional complications of peptide formulation or gene delivery safety validation. We used an in silico drug discovery approach to target the interaction interface between PEDF and 37 LR. Following cell based counter screening and binding validation, we characterized a hit compound's anti viability, activation of PEDF signaling-related genes, anti-wound healing, and anti-cancer signaling properties. This hit compound has potential for future development as a lead compound for treating tumor growth and inhibiting angiogenesis. PMID- 29464048 TI - Src is the primary target of aripiprazole, an atypical antipsychotic drug, in its anti-tumor action. AB - Aripiprazole (ARP) is an atypical anti-psychotic drug widely used to treat schizophrenia and bipolar disorder. The pharmacological effects of ARP on cancer cells are still poorly understood. In this study, anti-cancer effects of ARP on various malignant tumor cells and its molecular mechanism were further carefully examined by using cell proliferation assay, xenograft mouse model, immunoblotting analysis, migration assay, luciferase reporter gene assay, kinase assay, and overexpression strategy. Treatment with ARP induced cytotoxicity in U251 glioma cells, MKN-1 gastric adenosquamous carcinoma cells, and CT26 colon carcinoma cells. ARP suppressed cell proliferation of LN428, MDA-MB-231, and HEK293 cells. Pro-apoptotic factors active caspase-3, -8, and -9, as well as p53, were upregulated, whereas the protein and mRNA levels of anti-apoptotic factor B-cell lymphoma 2 (Bcl-2) decreased. In agreement with the in vitro results, ARP compound also significantly suppressed the growth of tumor masses formed by injecting CT26 colon cancer cells into mice. ARP treatment also effectively decreased the migratory ability of U251 glioma cells by downregulating metalloproteinase-9. Levels of phosphorylated Src, phosphorylated phosphatidylinositide 3-kinase (PI3K), and phosphorylated signal transducer and activator of transcription 3 (STAT3) were significantly decreased following ARP treatment. ARP compound reduced the kinase activity of Src. Our studies suggest that Src may be an important target molecule linked to the antitumor effects of ARP.

AB - Gastric cancer is the fifth most common cancer and the third leading cause of cancer deaths worldwide. South Korea is in first place with 9,180 death alone attributed to gastric cancer in 2013. Plenty of literature suggests the evasion of apoptosis is implicated in neurodegeneration, autoimmune diseases, and tumors development due to dysregulation in the apoptotic mechanism. Reduced apoptosis or its resistance in cancer cells plays a significant role in carcinogenesis. It's imperative to understand apoptosis, which provides the basis for novel targeted therapies that can induce cancer cell death or sensitize them to cytotoxic agents by regulating key factors like IAPs, MDM2, p53, caspases and much more. Studies have demonstrated that Scutellarein have the ability to inhibit several cancer cells by inducing apoptosis with both: Scutellarein monomers as well as scutellarein containing flavonoids. MTT results revealed that scutellarein inhibited cell viability in both dose and time dependent manner. Flow cytometry and western blot analysis showed that scutellarein induces apoptosis in both AGS and SNU-484 human gastric cancer cells and G2/M phase cell cycle arrest in SNU 484 cells. This study demonstrated that the Scutellarein on AGS and SNU-484 cells significantly inhibits cell proliferation and induces apoptotic cell death via down regulating MDM2 and activated the tumor suppresser protein p53, subsequently down regulating the IAP family proteins (cIAP1, cIAP2, and XIAP) leading to caspase-dependent apoptosis in AGS and SNU-484 cells. PMID- 29464050 TI - Assessing tumor molecular profiling to guide treatments for patients with advanced female genital tract malignancy. AB - Tumor molecular profiling has enabled selection of targeted therapies in a host of solid tumors. Here we used a retrospective clinical cohort, to evaluate the benefit of tailoring treatments for female genital tract malignancy, using tumor molecular profiles. Clinical outcome data for 112 patients was retrospectively separated into two groups. These either followed a matched treatment plan that incorporated at least one drug recommended according to their tumor profile and none that were expected to have no benefit (64 patients), or was unmatched with suggested treatments and received at least one drug that was anticipated to lack benefit for that tumor (48 patients). In the group of patients whose drugs matched those recommended by molecular profiling of their tumor, their overall survival was 593 days on average, compared to 449 days for patients that did not; removing drugs predicted to have no benefit from treatment regimens received after profiling increased survival by 144 days on average (P = 0.0265). In the matched treatment group, 30% of patients had died by the last time of monitoring, whereas this was 40% in the unmatched group (P = 0.2778). The IHC biomarker for the progesterone receptor was demonstrated to be prognostic for survival. PMID- 29464051 TI - Human papillomavirus E7 oncoprotein expression by keratinocytes alters the cytotoxic mechanisms used by CD8 T cells. AB - Cervical cancer is a malignant transformation of keratinocytes initiated by the E7 oncoprotein of human papillomavirus (HPV). These tumors are characterized by keratinocyte hyperproliferation and are often infiltrated with activated CD8 T cells. HPV infection confers changes to gain immunological advantage to promote chronic infection, and these persist with malignant transformation. We investigated the relative importance of the many redundant mechanisms of cytotoxicity used by CD8 T cells to kill keratinocytes expressing HPV E7 oncoprotein using extended-duration time-lapse microscopy that allows examination of cell-to-cell interactions during killing. E7 expression by keratinocytes increased susceptibility to cell-mediated killing. However, while killing of non transgenic keratinocytes was traditional, perforin-mediated, and caspase dependent, E7-expression favored killing by perforin-independent, caspase independent mechanisms. The roles of perforin, TNFalpha, IFNgamma, Fas/FasL and PD1/PD-L1 were graded according to target cell survival to produce a hierarchy of killing mechanisms utilized in killing E7-expressing cells. TNFalpha was essential for perforin-mediated killing of E7-expressing cells, but not perforin independent killing. IFNgamma facilitated killing by Fas/FasL interaction, especially in the absence of perforin. Additionally, expression of E7 offered protection from killing by up regulation of PD-L1, Fas and FasL expression on keratinocytes promoting fight-back by target cells, resulting in effector cell death. This study shows that keratinocytes expressing E7 are highly susceptible to killing by CD8 T cells, but utilizing different armamentarium. Down-regulation of CD8 T cell cytotoxicity in HPV-related tumors may be due to suppression by E7 expressing keratinocytes. Immunotherapy for HPV-related cancers may be improved by suppression of PD-L1, or by suppression of FasL. PMID- 29464052 TI - Epigenetic changes found in uterine decidual and placental tissues can also be found in the breast cancer microenvironment of the same unique patient: description and potential interpretations. AB - Microenvironmental properties are thought to be responsible for feto-maternal tolerance. Speculatively, ectopic expression of placental gene programs might also be related to cancer cells' ability to escape from immune vigilance mechanisms during carcinogenesis and cancer progression. Recently, we published the first human genomic evidence of similar immune related gene expression profiles in both placenta (placenta and decidual tissue) and cancer (both primary and metastatic) in the same patient with lymph-node positive breast carcinoma during pregnancy. Here we report the first epigenomic analysis of these tissue samples and describe their main findings, with respect to immune related genes regulation (over or under expressed) in cancer cells with regards placental tissues. We confirm significant similarities, and hierarchical clustering (both unsupervised and supervised), in CpG island methylation patterns between decidual/placental and cancer microenvironments, which cannot be easily explained by simple models or unique pathways. Several different cell types are probably involved in these complex immune regulation mechanisms. Cancers may somehow "hijack" gene programs evolved over millions of years to allow for feto-maternal tolerance in placental mammals in order to escape from immune vigilance and spread locally or to distant sites. PMID- 29464053 TI - Combination of a thioxodihydroquinazolinone with cisplatin eliminates ovarian cancer stem cell-like cells (CSC-LCs) and shows preclinical potential. AB - Cancer stem cell-like cells (CSC-LCs) contribute to drug resistance and recurrence of ovarian cancer. Strategies that can eradicate CSC-LCs are expected to substantially improve the outcome of ovarian cancer treatment. We have previously identified a class of thioxodihydroquinazolinone small molecules, which have strong synergistic antitumor activity with platinum drugs, the standard chemotherapeutic agents for ovarian cancer treatment. In the current study, using the activity of aldehyde dehydrogenase (ALDH) as a marker of CSC LCs, we demonstrated that the combination of thioxodihydroquinazolinone compound 19 with cisplatin is able to diminish ALDH-high CSC-LC populations in both platinum-resistant ovarian cancer cell lines and primary ovarian cancer cells from metastatic ascites of a cisplatin-resistant patient. Compound 19 enhanced the accumulation of intracellular cisplatin in ALDH-high ovarian CSC-LCs. The combination of compound 19 with cisplatin was also able to reduce the sphere forming capability of cisplatin-resistant ovarian cancer cells. Using a spheroid based in vitro metastasis model of ovarian cancer, we demonstrated that the co administration of compound 19 with cisplatin prevents ovarian cancer spheroid cells from attaching to substratum and spreading. In a cisplatin-resistant in vivo intraperitoneal xenograft mouse model, the combination of compound 19 with cisplatin significantly reduced tumor burden, as compared to cisplatin alone. Taken together, our study demonstrated that thioxodihydroquinazolinones represent a new class of agents that in combination with cisplatin are capable of eliminating CSC-LCs in ovarian cancer. Further development of thioxodihydroquinazolinone small molecules may yield a more effective treatment for cisplatin-resistant metastatic ovarian cancer. PMID- 29464054 TI - Rapid development of myeloproliferative neoplasm in mice with Ptpn11D61Y mutation and haploinsufficient for Dnmt3a. AB - PTPN11 gain-of-function mutation is the most common mutation found in patients with juvenile myelomonocytic leukemia and DNMT3A loss occurs in over 20% of acute myeloid leukemia patients. We studied the combined effect of both Ptpn11 gain-of function mutation (D61Y) and Dnmt3a haploinsufficiency on mouse hematopoiesis, the presence of which has been described in both juvenile myelomonocytic leukemia and acute myeloid leukemia patients. Double mutant mice rapidly become moribund relative to any of the other genotypes, which is associated with enlargement of the spleen and an increase in white blood cell counts. An increase in the mature myeloid cell compartment as reflected by the presence of Gr1+Mac1+ cells was also observed in double mutant mice relative to any other group. Consistent with these observations, a significant increase in the absolute number of granulocyte macrophage progenitors (GMPs) was seen in double mutant mice. A decrease in the lymphoid compartment including both T and B cells was noted in the double mutant mice. Another significant difference was the presence of extramedullary erythropoiesis with increased erythroid progenitors in the spleens of Dnmt3a+/ ;D61Y mice relative to other groups. Taken together, our results suggest that the combined haploinsufficiency of Dnmt3a and presence of an activated Shp2 changes the composition of multiple hematopoietic lineages in mice relative to the individual heterozygosity of these genes. PMID- 29464055 TI - [Neratinib + Valproate] exposure permanently reduces ERBB1 and RAS expression in 4T1 mammary tumors and enhances M1 macrophage infiltration. AB - The irreversible ERBB1/2/4 inhibitor neratinib has been shown in vitro to rapidly reduce the expression of ERBB1/2/4 and RAS proteins via autophagic/lysosomal degradation. We have recently demonstrated that neratinib and valproate interact to suppress the growth of 4T1 mammary tumors but had not defined whether the [neratinib + valproate] drug combination, in a mouse, had altered the biology of the 4T1 cells. Exposure of 4T1 mammary tumors to [neratinib + valproate] for three days resulted, two weeks later, in tumors that expressed less ERBB1, K-RAS, N-RAS, indoleamine-pyrrole 2,3-dioxygenase (IDO-1), ornithine decarboxylase (ODC) and had increased Class I MHCA expression. Tumors previously exposed to [neratinib + valproate] grew more slowly than those exposed to vehicle control and contained more CD8+ cells and activated NK cells. M1 but not M2 macrophage infiltration was significantly enhanced by the drug combination. In vitro exposure of 4T1 tumor cells to [neratinib + valproate] variably reduced the expression of histone deacetylases 1-11. In vivo, prior exposure of tumors to [neratinib + valproate] permanently reduced the expression of HDACs 1-3, 6 and 10. Combined knock down of HDACs 1/2/3 or of 3/10 rapidly reduced the expression IDO-1, and ODC and increased the expression of MHCA. H&E staining of normal tissues at animal nadir revealed no obvious cyto-architectural differences between control and drug-treated animals. We conclude that [neratinib + valproate] evolves 4T1 tumors to grow more slowly and to be more sensitive to checkpoint immunotherapy antibodies. PMID- 29464056 TI - Expression of Wnt-signaling pathway genes and their associations with miRNAs in colorectal cancer. AB - The Wnt-signaling pathway functions in regulating cell growth and thus is involved in the carcinogenic process of several cancers, including colorectal cancer. We tested the hypothesis that multiple genes in this signaling pathway are dysregulated and that miRNAs are associated with these dysregulated genes. We used data from 217 colorectal cancer (CRC) cases to evaluate differences in Wnt signaling pathway gene expression between paired CRC and normal mucosa and identify miRNAs that are associated with these genes. Gene expression data from RNA-Seq and miRNA expression data from Agilent Human miRNA Microarray V19.0 were analyzed. We focused on genes most strongly associated with CRC (fold change (FC) of >1.5 or <0.67) and that were statistically significant after adjustment for multiple comparisons. Of the 138 Wnt-signaling pathway genes examined, 27 were significantly down-regulated (FC<0.67) and 32 genes were significantly up regulated (FC>1.50) after adjusting for multiple comparisons. Thirteen of the 66 Wnt-signaling genes that were differentially expressed in CRC tumors were associated with differential expression of miRNAs. A total of 93 miRNA:mRNA associations were detected for these 13 genes. Of these 93 associations, 36 miRNA seed-region matches were observed, suggesting that miRNAs have both direct and indirect effects on Wnt-signaling pathway genes. In summary, our data supports the hypothesis that the Wnt-signaling pathway is dysregulated in CRC and suggest that miRNAs may importantly influence that dysregulation. PMID- 29464057 TI - Construction of key signal regulatory network in metastatic colorectal cancer. AB - There are many stages in the development and metastasis of colorectal cancer (CRC). In this study, we compared the differential expression genes in different stages of metastatic CRC. Then, we screened the continuously up-regulated genes and the continuously down-regulated genes that were associated with the development and metastasis of CRC. After analyzing the intersection of differential expression genes in each stage, we screened the continuously up regulated genes and deviated genes in the extracellular matrix and the continuously down-regulated genes and deviated genes in the mitochrondia of CRC. Then, we performed gene ontology enrichment analysis of the deviated genes in different phases, and we found that key molecular events occurred in the period extending from stage II to III (early stage of metastasis) of CRC. Furthermore, in this period we found that the chemotaxis of inflammatory cells had decreased in the extracellular matrix. On the other hand, the aerobic respiration had increased in the mitochondrion. Then, we constructed protein-protein interaction network of deviated genes in the extracellular matrix and mitochondrion. We used the network module and hub network to analyze the protein-protein interaction network. The network module analysis showed that the protein complex of VEGFA and CCL7-CCR3 is the key node in the extracellular matrix, while MAPK1 is the key node in the mitochondrion. The hub network analysis showed that the signal transmission chain FN1->SPARC->COL1A1->MMP2 is the key regulatory pathway for extracellular signal transmission. Furthermore, it also showed that CAV1->MAPK3 >RAF1->NR3C1->MAPK1->ESR1 is the key regulatory pathway for signal transmission in mitochondrion. PMID- 29464058 TI - Type IIB DNA topoisomerase is downregulated by trastuzumab and doxorubicin to synergize cardiotoxicity. AB - Despite heightened risk of cardiotoxicity associated with combination therapy of anthracyclines and trastuzumab in HER2-positive breast cancer patients, little research effort has been invested in exploring the molecular mechanisms of cardiotoxicity induced by this combination therapy. In this study, we demonstrate that trastuzumab downregulates both gene and protein expressions of type IIB DNA topoisomerase/DNA topoisomerase IIB (TOP2B), a major intracellular target mediating doxorubicin-induced cardiotoxicity, in human primary cardiomyocytes. This in turn induces DNA damage activity and DNA double strand breaks, which is indicated by the enhanced phosphorylation of H2AX (gammaH2AX) and ataxia telangiectasia and Rad3-related protein (ATR pS428) in trastuzumab-treated cardiomyocytes. Furthermore, concurrent or sequential treatment of doxorubicin and trastuzumab significantly increases the downregulation of the protein levels of TOP2B, enhances apoptosis and cell growth inhibition, and promotes production of reactive oxidative and nitrative species in human cardiomyocytes as compared to either trastuzumab or doxorubicin treatment, indicating augmentation of cardiotoxicity in combination therapy. Additionally, our data reveal that doxorubicin treatment increases the levels of ErbB2/HER2 expression in human cardiomyocytes as compared with that in cells not treated with doxorubicin, leading to the enhanced activity downstream of HER2 signaling. Consequently, this may render the cardiomyocytes to become addicted to HER2 signaling for survival under stressed conditions. Enhanced HER2 protein expression leaves cardiomyocytes more sensitive to trastuzumab treatment after doxorubicin exposure. This study provides molecular basis for significantly increased cardiotoxicity in cancer patients who are treated with anthracyclines and trastuzumab-based combination regimens. PMID- 29464059 TI - Characterization and metabolic synthetic lethal testing in a new model of SDH loss familial pheochromocytoma and paraganglioma. AB - Succinate dehydrogenase (SDH)-loss pheochromocytoma and paraganglioma (PPGL) are tumors driven by metabolic derangement. SDH loss leads to accumulation of intracellular succinate, which competitively inhibits dioxygenase enzymes, causing activation of pseudohypoxic signaling and hypermethylation of histones and DNA. The mechanisms by which these alterations lead to tumorigenesis are unclear, however. In an effort to fundamentally understand how SDH loss reprograms cell biology, we developed an immortalized mouse embryonic fibroblast cell line with conditional disruption of Sdhc and characterize the kinetics of Sdhc gene rearrangement, SDHC protein loss, succinate accumulation, and the resultant hypoproliferative phenotype. We further perform global transcriptomic, epigenomic, and proteomic characterization of changes resulting from SDHC loss, identifying specific perturbations at each biological level. We compare the observed patterns of epigenomic derangement to another previously-described immortalized mouse chromaffin cell model of SDHB loss, and compare both models to human SDH-loss tumors. Finally, we perform analysis of SDHC synthetic lethality with lactate dehydrogenase A (LDHA) and pyruvate carboxylase (PCX), which are important for regeneration of NAD+ and aspartate biosynthesis, respectively. Our data show that SDH-loss cells are selectively vulnerable to LDH genetic knock down or chemical inhibition, suggesting that LDH inhibition may be an effective therapeutic strategy for SDH-loss PPGL. PMID- 29464060 TI - Drp1/Fis1 interaction mediates mitochondrial dysfunction, bioenergetic failure and cognitive decline in Alzheimer's disease. AB - Mitochondrial dynamics, involving a balance between fusion and fission, regulates mitochondrial quality and number. Increasing evidence suggests that dysfunctional mitochondria play a role in Alzheimer's disease (AD). We observed that Drp1 interaction with one of the adaptors, Fis1, is significantly increased in Abeta treated neurons and AD patient-derived fibroblasts. P110, a seven-amino acid peptide, which specifically inhibits Drp1/Fis1 interaction without affecting the interaction of Drp1 with its other adaptors, attenuated Abeta42-induced mitochondrial recruitment of Drp1 and prevented mitochondrial structural and functional dysfunction in cultured neurons, in cells expressing mutant amyloid precursor protein (KM670/671NL), and in five different AD patient-derived fibroblasts. Importantly, sustained P110 treatment significantly improved behavioral deficits, and reduced Abeta accumulation, energetic failure and oxidative stress in the brain of the AD mouse model, 5XFAD. This suggests that Drp1/Fis1 interaction and excessive mitochondrial fission greatly contribute to Abeta-mediated and AD-related neuropathology and cognitive decline. Therefore, inhibiting excessive Drp1/Fis1-mediated mitochondrial fission may benefit AD patients. PMID- 29464061 TI - Natural and molecular history of prolactinoma: insights from a Prlr-/- mouse model. AB - Lactotroph adenoma, also called prolactinoma, is the most common pituitary tumor but little is known about its pathogenesis. Mouse models of prolactinoma can be useful to better understand molecular mechanisms involved in abnormal lactotroph cell proliferation and secretion. We have previously developed a prolactin receptor deficient (Prlr-/- ) mouse, which develops prolactinoma. The present study aims to explore the natural history of prolactinoma formation in Prlr-/- mice, using hormonal, radiological, histological and molecular analyses to uncover mechanisms involved in lactotroph adenoma development. Prlr-/- females develop large secreting prolactinomas from 12 months of age, with a penetrance of 100%, mimicking human aggressive densely granulated macroprolactinoma, which is a highly secreting subtype. Mean blood PRL measurements reach 14 902 ng/mL at 24 months in Prlr-/- females while PRL levels were below 15 ng/mL in control mice (p < 0.01). By comparing pituitary microarray data of Prlr-/- mice and an estrogen induced prolactinoma model in ACI rats, we pinpointed 218 concordantly differentially expressed (DE) genes involved in cell cycle, mitosis, cell adhesion molecules, dopaminergic synapse and estrogen signaling. Pathway/gene-set enrichment analyses suggest that the transcriptomic dysregulation in both models of prolactinoma might be mediated by a limited set of transcription factors (i.e., STAT5, STAT3, AhR, ESR1, BRD4, CEBPD, YAP, FOXO1) and kinases (i.e., JAK2, AKT1, BRAF, BMPR1A, CDK8, HUNK, ALK, FGFR1, ILK). Our experimental results and their bioinformatic analysis provide insights into early genomic changes in murine models of the most frequent human pituitary tumor. PMID- 29464062 TI - Cell-cell fusion as a mechanism of DNA exchange in cancer. AB - Cell-cell fusion describes the process by which two cells combine their plasma membranes and become a single cell, possessing and retaining certain genetic information from each parent cell. Here, using a Cre-loxP-based method initially developed to investigate extracellular vesicle targeting, we found that cancer cells spontaneously and rapidly deliver DNA to non-cancer cells in vitro via a cell-cell fusion event. The resulting hybrid cells were aneuploid and possessed enhanced clonal diversity and chemoresistance compared to non-hybrid cancer cells. We also observed cell-cell fusion to occur in vivo between melanoma cells and non-cancer cells of both hematopoietic and non-hematopoietic lineages. These findings suggest that cell-cell fusion occurs during the natural progression of cancer and show that this mechanism has the potential to cause massive genomic alterations that are observed in cancer. Furthermore, these findings somewhat contradict recent publications suggesting that the Cre-loxP method measures only extracellular vesicle-mediated intercellular communication. PMID- 29464063 TI - Combined inhibition of CDK and HDAC as a promising therapeutic strategy for both cutaneous and uveal metastatic melanoma. AB - Very little to no improvement in overall survival has been seen in patients with advanced non-resectable cutaneous melanoma or metastatic uveal melanoma in decades, highlighting the need for novel therapeutic options. In this study we investigated as a potential novel therapeutic intervention for both cutaneous and uveal melanoma patients a combination of the broad spectrum HDAC inhibitor quisinostat and pan-CDK inhibitor flavopiridol. Both drugs are currently in clinical trials reducing time from bench to bedside. Combining quisinostat and flavopiridol shows a synergistic reduction in cell viability of all melanoma cell lines tested, irrespective of their driver mutations. This synergism was also observed in BRAFV600E mutant melanoma that had acquired resistance to BRAF inhibition. Mechanistically, loss of cell viability was, at least partly, due to induction of apoptotic cell death. The combination was also effectively inducing tumor regression in a preclinical setting, namely a patient-derived tumor xenograft (PDX) model of cutaneous melanoma, without increasing adverse effects. We propose that the quisinostat/flavopiridol combination is a promising therapeutic option for both cutaneous and uveal metastatic melanoma patients, independent of their mutational status or (acquired) resistance to BRAF inhibition. PMID- 29464064 TI - Translational study reveals a two-faced role of RBM3 in pancreatic cancer and suggests its potential value as a biomarker for improved patient stratification. AB - Periampullary adenocarcinoma, including pancreatic cancer, is a heterogeneous group of tumors with dismal prognosis, partially due to lack of reliable targetable and predictive biomarkers. RNA-binding motif protein 3 (RBM3) has previously been shown to be an independent prognostic and predictive biomarker in several types of cancer. Herein, we examined the prognostic value of RBM3 in periampullary adenocarcinoma, as well as the effects following RBM3 suppression in pancreatic cancer cells in vitro. RBM3 mRNA levels were examined in 176 pancreatic cancer patients from The Cancer Genome Atlas. Immunohistochemical expression of RBM3 was analyzed in tissue microarrays with primary tumors and paired lymph node metastases from 175 consecutive patients with resected periampullary adenocarcinoma. Pancreatic cancer cells were transfected with anti RBM3 siRNA in vitro and the influence on cell viability following chemotherapy, transwell migration and invasion was assessed. The results demonstrated that high mRNA-levels of RBM3 were significantly associated with a reduced overall survival (p = 0.026). RBM3 protein expression was significantly higher in lymph node metastases than in primary tumors (p = 0.005). High RBM3 protein expression was an independent predictive factor for the effect of adjuvant chemotherapy and an independent negative prognostic factor in untreated patients (p for interaction = 0.003). After siRNA suppression of RBM3 in vitro, pancreatic cancer cells displayed reduced migration and invasion compared to control, as well as a significantly increased resistance to chemotherapy. In conclusion, the strong indication of a positive response predictive effect of RBM3 expression in pancreatic cancer may be highly relevant in the clinical setting and merits further validation. PMID- 29464065 TI - The presence of PD-1 positive tumor infiltrating lymphocytes in triple negative breast cancers is associated with a favorable outcome of disease. AB - Triple negative breast cancer patients have a poor course of disease not least because of limited treatment options however immunotherapy by targeting the PD 1/PD-L1 checkpoint system is a promising strategy to improve the outcome. Here we systematically investigated the expression of PD-1 on tumor infiltrating lymphocytes and PD-L1 on both tumor and infiltrated immune cells. Moreover, the PD-L1 gene status in tumor cells was assessed. 103 tissue microarray samples derived from triple negative breast cancer specimens were immunohistochemically stained against PD-1 and PD-L1. Dual marker fluorescence in-situ hybridization was applied to the PD-L1 gene and centromere region of chromosome 9. The disease free and overall survival rates were determined as a function of the PD-1/PD-L1 status. A slight gain of the PD-L1 gene region was found in 55% of all samples but an elevated PD-L1/cen9 ratio was rather rare (7%). An increased gene dose is not associated with an enhanced protein expression and the PD-L1 expression only weakly correlates with the amount of immune cell infiltration. Instead, we found an association of PD-L1 expression on tumor and immune cells, respectively. Notably, the PD-1 expression on immune cells is associated with a favorable disease free and overall survival. PD-1 expression indicates an enhanced immunological anti-tumor activity and represents a favorable prognostic impact. A deeper understanding of factors that affect the regulation and function of the PD 1/PD-L1 system is required to establish predictive variables and to utilize the system for therapeutic intervention of triple negative breast cancer patients. PMID- 29464066 TI - Near infrared fluorescence imaging of EGFR expression in vivo using IRDye800CW nimotuzumab. AB - Nimotuzumab is a humanized anti-epidermal growth factor receptor (EGFR) monoclonal antibody that is approved in many countries for the treatment of EGFR positive cancers. Near infrared (NIR) fluorescent dye-labeled antibodies represent an attractive class of image-guided surgical probes because of their high specificity, tumor uptake, and low dissociation from tumor cells that express the antigen. In this study, we developed a NIR fluorescent dye-labeled nimotuzumab immunoconjugate, IRDye800CW-nimotuzumab, and evaluated in vitro binding with EGFR-positive cells, in vivo tumor uptake by NIR fluorescent imaging, and ex vivo biodistribution. There was no difference in binding between nimotuzumab and IRDye800CW-nimotuzumab to EGFR-positive cells. In mice bearing EGFR-positive xenografts, IRDye800CW-nimotuzumab uptake peaked at 4 days post injection and slowly decreased thereafter with high levels of accumulation still observed at 28 days post injection. In EGFR-positive xenografts, IRDye800CW nimotuzumab showed more than 2-fold higher uptake in tumors compared to IRDye800CW-cetuximab. In addition, liver uptake of IRDye800CW-nimotuzumab was two fold lower than cetuximab. The lower liver uptake of IRDye800CW-nimotuzumab could have implications on the selected dose for clinical trials of the immunoconjugate. In summary, this study shows that nimotuzumab is a good candidate for NIR fluorescent imaging and image-guided surgery. PMID- 29464067 TI - Gene aberration profile of tumors of adolescent and young adult females. AB - There has been little improvement in the prognosis for adolescent and young adult (AYA) tumor patients. Hence, there is an urgent need to understand the etiology of tumor development and identify actionable gene aberrations to improve prevention and therapy. Here, 76 sporadic tumors (48 breast, 22 ovarian, and six uterine) from 76 AYA females (age range, 25-39 years) were subjected to whole exome and RNA sequencing to determine their mutational signatures and actionable gene profiles. Two individuals with breast cancer (4.2% of cases) and one with ovarian cancer (5.3% of cases) carried germline BRCA2 mutations. The two cases with breast tumors also each carried an additional deleterious germline mutation: one in TP53 and the other in CHEK2. Mutational signature analysis of the 76 tumors indicated that spontaneous deamination of 5-methylcytosine and activity of the APOBEC cytidine deaminase protein family are major causes of mutagenesis. In addition, 18 breast or ovarian tumors (18/70, 26%), including the three cases with germline BRCA2 mutations, exhibited a predominant "BRCAness" mutational signature, an indicator of functional BRCA1/BRCA2 deficiency. Actionable aberrations and high tumor mutation burdens were detected in 24 breast (50%), 17 ovarian (77%), and five uterine (83%) tumor cases. Thus, mutational processes and aberrant genes in AYA tumors are largely shared with those identified in non-AYA tumors. The efficacy of molecular targeting and immune checkpoint inhibitory therapies should be explored for both AYA and non-AYA patients. PMID- 29464068 TI - Prognostic significance of heparanase expression in primary and metastatic breast carcinoma. AB - High levels of heparanase are detected in many types of tumors, associated with bad prognosis. Typically, heparanase levels are evaluated in a biopsy taken from the primary lesion, whereas its expression by the resulting metastases is most often unresolved. This becomes critically important as anti-heparanase compounds enter advanced clinical trials. Here, we examined the expression of heparanase in pairs of primary and the resulting distant metastases of breast carcinoma. Interestingly, we found that heparanase expression in the metastatic lesion does not always reflect its expression in the primary tumor. Accordingly, in some cases, the primary lesion was stained positive for heparanase while the metastasis stained negative, and vice versa. Heparanase discordance occurred in 38% of the patients, higher than that reported for hormone receptors, and was associated with bad prognosis. Thus, examination of heparanase levels in the tumor metastases should be evaluated for most efficient precision medicine applying heparanase inhibitors. Furthermore, we found that in stage I breast cancer patients strong heparanase staining is associated with shorter overall survival. Thus, heparanase levels can assist in the diagnosis and in determining the necessity and type of treatment in early stage breast cancer. PMID- 29464069 TI - Determination of candidate metabolite biomarkers associated with recurrence of HCV-related hepatocellular carcinoma. AB - Hepatitis C virus (HCV) infection is associated with a high risk of developing hepatocellular carcinoma (HCC) and HCC recurrence remains the primary threat to outcomes after curative therapy. In this study, we compared recurrent and non recurrent HCC patients treated with radiofrequency ablation (RFA) in order to identify characteristic metabolic profile variations associated with HCC recurrence. Gas chromatography-mass spectrometry (GC-MS) -based metabolomic analyses were conducted on serum samples obtained before and after RFA therapy. Significant variations were observed in metabolites in the glycerolipid, tricarboxylic acid (TCA) cycle, fatty acid, and amino acid pathways between recurrent and non-recurrent patients. Observed differences in metabolites associated with recurrence did not coincide before and after treatment except for fatty acids. Based on the comparison of serum metabolomes between recurrent and non-recurrent patients, key discriminatory metabolites were defined by a random forest (RF) test. Two combinations of these metabolites before and after RFA treatment showed outstanding performance in predicting HCV-related HCC recurrence, they were further confirmed by an external validation set. Our study showed that the determined combination of metabolites may be potential biomarkers for the prediction of HCC recurrence before and after RFA treatment. PMID- 29464070 TI - 2-Amino-3-methylcarboxy-5-heptyl-thiophene (TJ191) is a selective anti-cancer small molecule that targets low TbetaRIII-expressing malignant T-cell leukemia/lymphoma cells. AB - Current chemotherapy regimens often include non-specific cytostatic/cytotoxic drugs, which do not distinguish between normal and tumor cells, therefore causing considerable systemic toxicity. We previously reported the synthesis and anti proliferative activity of a novel synthetic 2-aminothiophene-3-carboxylic acid ester derivative TJ191 that selectively targets certain cancer cells without affecting the proliferation of other cancer cells or normal fibroblasts or immune cells (over 600-fold selectivity). In a panel of ten human T-cell leukemia/lymphoma cell lines and peripheral blood mononuclear cells (PBMCs), we now found that transforming growth factor beta type III receptor (TbetaRIII) expression correlates inversely with TJ191 sensitivity, but not with sensitivity against classical chemotherapeutic drugs, thus serving as a predictive marker for TJ191 sensitivity. Accordingly, CRISPR/Cas9-mediated knock-out of TbetaRIII partially restored the susceptibility of TJ191-resistant cells to this novel compound. Our findings highlight TJ191 as a potent and selective anti-cancer molecule with pronounced activity against human malignant T-cells expressing low levels of TbetaRIII.

AB - Castration-resistant prostate cancer (CRPC) frequently develops after initial standard radiation and androgen deprivation therapy, leaving patients with limited further treatment options. Androgen receptor (AR) is a transcription factor that plays a key role in the initiation and progression of prostate cancer. p53, a major tumor suppressor that is rarely mutated in early-stages of prostate cancer, is often deregulated during prostate cancer progression. Here, we report an unusual co-amplification of MDM2 and MDMX, two crucial negative regulators of p53, in CRPC datasets. We demonstrate that combinatorial inhibition of MDM2 and MDMX, with nutlin-3 and NSC207895 respectively, has a profound inhibitory effect on cell proliferation of androgen-responsive, wild-type TP53 gene carrying prostate cancer cells LNCaP and 22Rv1. We further show that the combinatorial inhibition of MDM2 and MDMX not only activates p53, but also decreases cellular levels of AR and represses its function. Additionally, co expression of MDM2 and MDMX stabilizes AR. Together, our results indicate that combinatorial inhibition of MDM2 and MDMX may offer a novel compelling strategy for prostate cancer therapy. PMID- 29464072 TI - LIMD1 is induced by and required for LMP1 signaling, and protects EBV-transformed cells from DNA damage-induced cell death. AB - LIMD1 (LIM domain-containing protein 1) is considered as a tumor suppressor, being deregulated in many cancers to include hematological malignancies; however, very little is known about the underlying mechanisms of its deregulation and its roles in carcinogenesis. Epstein-Barr Virus (EBV) is associated with a panel of malignancies of lymphocytic and epithelial origin. Using high throughput expression profiling, we have previously identified LIMD1 as a common marker associated with the oncogenic transcription factor IRF4 in EBV-related lymphomas and other hematological malignancies. In this study, we have identified potential conserved IRF4- and NFkappaB-binding motifs in the LIMD1 gene promoter, and both are demonstrated functional by promoter-reporter assays. We further show that LIMD1 is partially upregulated by EBV latent membrane protein 1 (LMP1) via IRF4 and NFkappaB in EBV latency. As to its role in the setting of EBV latent infection, we show that LIMD1 interacts with TRAF6, a crucial mediator of LMP1 signal transduction. Importantly, LIMD1 depletion impairs LMP1 signaling and functions, potentiates ionomycin-induced DNA damage and apoptosis, and inhibits p62-mediated selective autophagy. Taken together, these results show that LIMD1 is upregulated in EBV latency and plays an oncogenic role rather than that of a tumor suppressor. Our findings have identified LIMD1 as a novel player in EBV latency and oncogenesis, and open a novel research avenue, in which LIMD1 and p62 play crucial roles in linking DNA damage response (DDR), apoptosis, and autophagy and their potential interplay during viral oncogenesis. PMID- 29464073 TI - The possible existence of occult metastasis in patients with ovarian clear-cell carcinoma who underwent complete resection without any residual tumours. AB - The objective of this study was to estimate the frequency of possible occult metastasis through long-term survival analyses in patients with clear cell carcinoma (CCC) who had undergone complete resection. During the period of 1990 2015, 799 patients with stage I-IV CCC were identified in the TOTSG database. Of these, a total of 528 patients without a residual tumor were enrolled in the study and classified into four groups: Group 1: FIGO stage IA-IB (N=104), Group 2: FIGO stage IC1 (N=170), Group 3: FIGO stage IC2/IC3 (N=98), and Group 4: FIGO stage II-III (no residual tumor: N=156). Cumulative incidences of recurrence (CIR) and death (CID) were examined. The median age was 54, ranging from 29-87. The 5-year CIR / CID of each group were as follows: Group 1 (7.3% / 3.8%), Group 2 (14.3% / 10.2%), Group 3 (37.7% / 18.4%), and Group 4 (46.5% / 33.8%), respectively {P<0.0001 (recurrence) / P<0.0001 (death)}. Furthermore, confining analysis to relapsed patients, 1-, 2-, and 3-year CID after recurrence were 41.5, 60.9, and 73.9, respectively. Confining analyses to patients with sufficient information about adjuvant chemotherapy, the 5-year CIR / CID of stage IA-IC1 patients with or without chemotherapy were as follows: recurrence {13.0% (yes) / 9.6% (no)}, death {9.3% (yes) / 4.2% (no)}, respectively {P=0.947 (CIR) / P=0.224 (CID)}. CCC patients staged greater than IC2/ IC3 show a marked risk of mortality, even after complete surgical resection. PMID- 29464074 TI - A lethal synergy induced by phellinus linteus and camptothecin11 in colon cancer cells. AB - Side effects of anti-cancer drugs are always challenging for effective cancer treatments. The polysaccharides extracted from Phellinus linteus (PLGL) have been widely used in treating cancers. However, the mechanism by which PLGL antagonizes cancerous growth has not been fully investigated. The current study demonstrated that human colon cancer HCT116 and HT29 cells became highly susceptible to cell death when being co-treated with PLGL and low dose of camptothecin11 (CPT11, a topoisomerase inhibitor-based drug), the efficacy of which was comparable as that generated by the high dose of CPT11. However, the co-treatment, unlike high doses of CPT11, was not cytotoxic to the control immortalized colon Caco-2 cells. The co-treatment caused high percentages of the colon cancer cells to accumulate in S phase of the cell cycle, which was also seen in the same cells received the high dose of CPT11 treatment. Chk1 was phosphorylated, and then rapidly degraded in the cancer cells treated with the high dose of CPT11 or co-treatment, but not in the cells treated with PLGL alone or low doses of CPT11. PLGL appeared enhancing CPT11 inhibitory effect on topoisomerase, and Chk1 degradatopm in the cancer cells. Furthermore, cyclin E (clnE) became unstable at the transcription level in co-treated or PLGL-treated colon cancer cells. The data suggested that PLGL functions in two ways to achieve its lethal synergy with CPT11 in colon cancer cells. Our findings are of potential significance as PLGL represents a promising medicine for overcoming the side effects of CPT11 and perhaps also for improving other CPTs-based regimens. PMID- 29464075 TI - Interleukin 8 activity influences the efficacy of adenoviral oncolytic immunotherapy in cancer patients. AB - After the landmark approval of T-VEC, oncolytic viruses are finding their way to the clinics. However, response rates have still room for improvement, and unfortunately there are currently no available markers to predict responses for oncolytic immunotherapy. Interleukin 8 (IL-8) production is upregulated in many cancers and it also connects to several pathways that have been shown to impair the efficacy of adenoviral immunotherapy. We studied the role of IL-8 in 103 cancer patients treated with oncolytic adenoviruses. We found high baseline serum IL-8 concentration to be independently associated with poor prognosis (p<0.001). Further, normal baseline IL-8 was associated with improved prognostic potential of calculation of the neutrophil-to-lymphocyte ratio (p<0.001). Interestingly, a decrease in IL-8 concentration after treatment with oncolytic adenovirus predicted better overall survival (p<0.001) and higher response rate, although this difference was not significant (p=0.066). We studied the combination of adenovirus and IL-8 neutralizing antibody ex vivo in single cell suspensions and in co-cultures of tumor-associated CD15+ neutrophils and CD3+ tumor-infiltrating lymphocytes derived from fresh patient tumor samples. These results indicate a role for IL-8 as a biomarker in oncolytic virotherapy, but additionally provide a rationale for targeting IL-8 to improve treatment efficacy. In conclusion, curtailing the activity of IL-8 systemically or locally in the tumor microenvironment could improve anti-tumor immune responses resulting in enhanced efficacy of adenoviral immunotherapy of cancer. PMID- 29464076 TI - Quantitative radiomic profiling of glioblastoma represents transcriptomic expression. AB - Quantitative imaging biomarkers have increasingly emerged in the field of research utilizing available imaging modalities. We aimed to identify good surrogate radiomic features that can represent genetic changes of tumors, thereby establishing noninvasive means for predicting treatment outcome. From May 2012 to June 2014, we retrospectively identified 65 patients with treatment-naive glioblastoma with available clinical information from the Samsung Medical Center data registry. Preoperative MR imaging data were obtained for all 65 patients with primary glioblastoma. A total of 82 imaging features including first-order statistics, volume, and size features, were semi-automatically extracted from structural and physiologic images such as apparent diffusion coefficient and perfusion images. Using commercially available software, NordicICE, we performed quantitative imaging analysis and collected the dataset composed of radiophenotypic parameters. Unsupervised clustering methods revealed that the radiophenotypic dataset was composed of three clusters. Each cluster represented a distinct molecular classification of glioblastoma; classical type, proneural and neural types, and mesenchymal type. These clusters also reflected differential clinical outcomes. We found that extracted imaging signatures does not represent copy number variation and somatic mutation. Quantitative radiomic features provide a potential evidence to predict molecular phenotype and treatment outcome. Radiomic profiles represents transcriptomic phenotypes more well. PMID- 29464077 TI - Complement C4d-specific antibodies for the diagnosis of lung cancer. AB - Development of molecular markers that help to identify high-risk individuals or diagnose indeterminate pulmonary nodules could have a major impact on lung cancer clinical management. In this study, we evaluated the diagnostic potential of a newly-developed ELISA that specifically detects complement C4d. We measured this marker in five independent cohorts of plasma and bronchoalveolar lavage samples from lung cancer patients and controls. In case-control studies, the area under the ROC curve for the diagnosis of lung cancer was 0.82 (95%CI = 0.72-0.92) in plasma samples, and 0.80 (95%CI = 0.69 to 0.90) in bronchoalveolar lavage fluids. In a set of plasma samples from the MILD CT-screening trial, the assay was unable to discriminate between asymptomatic high-risk individuals with or without early stage lung cancer. On the contrary, in two independent cohorts of individuals with indeterminate pulmonary nodules, plasma samples from patients with lung cancer nodules presented higher levels of C4d than those from patients with benign nodules. Using a target population of patients with 8 to 30 mm nodules, the test identified likely benign lung nodules with 84% negative predictive value and 54% positive predictive value, at 89% specificity and 44% sensitivity. In conclusion, the specific determination of C4d may serve as an adjunct to current clinical practice in the diagnosis of indeterminate pulmonary nodules. PMID- 29464078 TI - Effects of a small molecule R-spondin-1 substitute RS-246204 on a mouse intestinal organoid culture. AB - Organoids, a multi-cellular and organ-like structure cultured in vitro, can be used in a variety of fields such as disease modeling, drug discovery, or cell therapy development. When organoids derived from Lgr5 stem cells are cultured ex vivo, recombinant R-spondin-1 protein should be added at a high concentration for the initiation and maintenance of the organoids. Because the addition of large amounts of R-spondin-1 greatly increases the cost of organoids, the organoids grown with R-spondin-1 are not practical for large-scale drug screening and for the development of therapeutic agents. In this study, we tried to find a R spondin-1 substitute compound that is able initiate small intestinal organoids without the use of the R-spondin-1 protein; thus, using organoid media that each included one compound from among an 8,364 compound library instead of R-spondin 1, we observed whether organoids were established from the crypts of the small intestine. As a result, we found one compound that could promote the initial formation and growth of enteroids in the medium without R-spondin-1 and named it RS-246204. The enteroids grown with RS-246204 had a similar differentiation capacity as well as self-renewal capacity as the enteroids grown with R-spondin 1. Furthermore, the RS-246204-derived enteroids could successfully produce the forskolin induced swelling and the organoid based epithelial to mesenchymal transition model. This compound could be used for developing a cost-efficient culturing method for intestinal organoids as well as for exploring Lgr5 signaling, intestinal stem cell physiology and therapeutics for GI tract diseases. PMID- 29464079 TI - Differential tumor biological role of the tumor suppressor KAI1 and its splice variant in human breast cancer cells. AB - The tetraspanin and tumor suppressor KAI1 is downregulated or lost in many cancers which correlates with poor prognosis. KAI1 acts via physical/functional crosstalk with other membrane receptors. Also, a splice variant of KAI1 (KAI1-SP) has been identified indicative of poor prognosis. We here characterized differential effects of the two KAI1 variants on tumor biological events involving integrin (alphavbeta3) and/or epidermal growth factor receptor (EGF-R). In MDA-MB-231 and -435 breast cancer cells, differential effects were documented on the expression levels of the tumor biologically relevant integrin alphavbeta3 which colocalized with KAI1-WT but not with KAI1-SP. Cellular motility was assessed by video image processing, including motion detection and vector analysis for the quantification and visualization of cell motion parameters. In MDA-MB-231 cells, KAI1-SP provoked a quicker wound gap closure and higher closure rates than KAI1-WT, also reflected by different velocities and average motion amplitudes of singular cells. KAI1-SP induced highest cell motion adjacent to the wound gap borders, whereas in MDA-MB-435 cells a comparable induction of both KAI1 variants was noticed. Moreover, while KAI1-WT reduced cell growth, KAI1-SP significantly increased it going along with a pronounced EGF-R upregulation. KAI1 SP-induced cell migration and proliferation was accompanied by the activation of the focal adhesion and Src kinase. Our findings suggest that splicing of KAI1 does not only abrogate its tumor suppressive functions, but even more, promotes tumor biological effects in favor of cancer progression and metastasis. PMID- 29464080 TI - Effects of interactions between common genetic variants and alcohol consumption on colorectal cancer risk. AB - Background: Genome-wide association studies (GWAS) have identified approximately 40 common genetic loci associated with colorectal cancer risk. To investigate possible gene-environment interactions (GEIs) between GWAS-identified single nucleotide polymorphisms (SNPs) and alcohol consumption with respect to colorectal cancer, a hospital-based case-control study was conducted. Results: Higher levels of alcohol consumption as calculated based on a standardized definition of a drink (1 drink=12.5g of ethanol) were associated with increased risk of colorectal cancer (OR=2.47, 95% CI=1.62-3.76 for heavy drinkers [>50g/day] compared to never drinkers; ptrend<0.01). SNP rs6687758 near the DUSP10 gene at 1q41 had a statistically significant interaction with alcohol consumption in analyses of standardized drinks (p=4.6*10-3), although this did not surpass the corrected threshold for multiple testing. When stratified by alcohol consumption levels, in an additive model the risk of colorectal cancer associated with the G allele of rs6687758 tended to increase among individuals in the heavier alcohol consumption strata. A statistically significant association between rs6687758 and colorectal cancer risk was observed among moderate alcohol drinkers who consumed between >12.5 and <=50g of alcohol per day (OR=1.46, 95% CI=1.01-2.11). Methods: A total of 2,109 subjects (703 colorectal cancer patients and 1,406 healthy controls) were recruited from the Korean National Cancer Center. For genotyping, 30 GWAS-identified SNPs were selected. A logistic regression model was used to evaluate associations of SNPs and alcohol consumption with colorectal cancer risk. We also tested GEIs between SNPs and alcohol consumption using a logistic model with multiplicative interaction terms. Conclusions: Our results suggest that SNP rs6687758 at 1q41 may interact with alcohol consumption in the etiology of colorectal cancer. PMID- 29464081 TI - DAPK and CIP2A are involved in GAS6/AXL-mediated Schwann cell proliferation in a rat model of bilateral cavernous nerve injury. AB - Purpose: Impotence is one of the major complications occurring in prostate cancer patients after radical prostectomy (RP). Self-repair of the injured nerve has been observed in animal models and in patients after RP. However, the downstream signalling is not well documented. Here, we found that the DAPK/CIP2A complex is involved in GAS6/AXL-related Schwann cell proliferation. Materials and Methods: The 3 groups were a sham group, a 14-day post-bilateral cavernous nerve injury (BCNI) group and a 28-day post-BCNI group. Erectile function was assessed and immunohistochemistry was performed. The rat Schwann cell RSC96 line was chosen for gene knockdown, cell viability, western blot, immunofluorescence and co immunoprecipitation assays. Results: The intracavernosal pressure was low on the 14th day after BCNI and partially increased by the 28th day. GAS6 and p-AXL expression gradually increased in the cavernous nerve after BCNI. RSC96 cells incubated with a GAS6 ligand showed increased levels of p-ERK1/2 and p-AKT. Moreover, DAPK and CIP2A.p-AXL and p-DAPK and CIP2A complexes were identified by both immunoblotting and co-immunoprecipitation. Conclusion: The DAPK/CIP2A complex is involved in GAS6/AXL-related Schwann cell proliferation. CIP2A inhibits PP2A activity, which results in p-DAPK(S308) maintenance and promotes Schwann cell proliferation. CIP2A is a potential target for the treatment of nerve injury after RP. PMID- 29464082 TI - MYC-family protein overexpression and prominent nucleolar formation represent prognostic indicators and potential therapeutic targets for aggressive high-MKI neuroblastomas: a report from the children's oncology group. AB - Neuroblastomas with a high mitosis-karyorrhexis index (High-MKI) are often associated with MYCN amplification, MYCN protein overexpression and adverse clinical outcome. However, the prognostic effect of MYC-family protein expression on these neuroblastomas is less understood, especially when MYCN is not amplified. To address this, MYCN and MYC protein expression in High-MKI cases (120 MYCN amplified and 121 non-MYCN amplified) was examined by immunohistochemistry. The majority (101) of MYCN-amplified High-MKI tumors were MYCN(+), leaving one MYC(+), 2 both(+), and 16 both(-)/(+/-), whereas non-MYCN amplified cases appeared heterogeneous, including 7 MYCN(+), 36 MYC(+), 3 both(+), and 75 both(-)/(+/-) tumors. These MYC-family proteins(+), or MYC-family driven tumors, were most likely to have prominent nucleolar (PN) formation (indicative of augmented rRNA synthesis). High-MKI neuroblastoma patients showed a poor survival irrespective of MYCN amplification. However, patients with MYC family driven High-MKI neuroblastomas had significantly lower survival than those with non-MYC-family driven tumors. MYCN(+), MYC-family protein(+), PN(+), and clinical stage independently predicted poor survival. Specific inhibition of hyperactive rRNA synthesis and protein translation was shown to be an effective way to suppress MYC/MYCN protein expression and neuroblastoma growth. Together, MYC-family protein overexpression and PN formation should be included in new neuroblastoma risk stratification and considered for potential therapeutic targets. PMID- 29464083 TI - TGF-beta2-induced EMT is dampened by inhibition of autophagy and TNF-alpha treatment. AB - Hepatocellular carcinoma (HCC) typically develops in a chronic inflammatory setting causal to release of a plethora of growth factors and cytokines. However, the molecular effect of these cytokines on HCC progression is poorly understood. In this study, we exposed HCC cells to TGF-beta2 (Transforming Growth Factor beta2), which resulted in a significant elevation of EMT (Epithelial to Mesenchymal Transition) like features. Molecular analysis of EMT markers showed an increase at both RNA and protein levels upon TGF-beta2 administration along with up-regulation of TGF-beta-induced Smad signaling. Induction of EMT was associated with a simultaneous increase in reactive oxygen species (ROS) and cytostasis of TGF-beta2-treated cells. Importantly, quenching of ROS resulted in a significant promotion of TGF-beta2-induced EMT. Furthermore, cells treated with TGF-beta2 also showed an enhanced autophagic flux. Interestingly, inhibition of autophagy by chloroquine-di-phosphate (CQDP) or siRNA-mediated ablation of ATG5 drastically inhibited TGF-beta2-induced EMT. Autophagy inhibition significantly increased ROS levels promoting apoptosis. It was further observed that pro inflammatory cytokine like, TNF-alpha (Tumor Necrosis Factor-alpha) can antagonize TGF-beta2-induced response by down-regulating autophagy, increasing ROS levels and thus inhibiting EMT in HCC cells. This inhibitory effect of TNF alpha is serum-independent. Transcriptomic analysis through RNA sequencing was further performed which validated that TGF-beta2-induced autophagic genes are inhibited by TNF-alpha treatment suppressing EMT. Our study suggests that autophagy plays a pro-metastatic role facilitating EMT by regulating ROS levels in HCC cells and TNF-alpha can suppress EMT by inhibiting autophagy. We provide unique mechanistic insights into the role of TGF-beta2 in HCC cells, along with appropriate cues to effectively control the disease. PMID- 29464084 TI - Lysine-specific demethylase 1 inhibitors prevent teratoma development from human induced pluripotent stem cells. AB - Human induced pluripotent stem cells (hiPSCs) are creating great expectations for regenerative medicine. However, safety strategies must be put in place to guard against teratoma formation after transplantation of hiPSC-derived cells into patients. Recent studies indicate that epigenetic regulators act at the initial step of tumorigenesis. Using gain-of-function and loss-of-function approaches, we show here that the expression and function of lysine-specific demethylase 1 (LSD1) are tightly regulated in hiPSCs, and their deregulation underlies the development of teratomas. Consistent with these results, we demonstrate that an LSD1 inhibitor, S2157, prevented teratoma formation from hiPSCs transplanted into immunodeficient mice. This novel action of LSD1 and the effects of its inhibition potentially allow for the development of new clinical applications and therapeutic strategies using hiPSCs. PMID- 29464085 TI - Intravesicular epidermal growth factor receptor subject to retrograde trafficking drives epidermal growth factor-dependent migration. AB - The Epidermal Growth Factor Receptor (EGFR) is frequently mutated and overexpressed in metastatic cancer. Although EGFR is a transmembrane tyrosine kinase localized to the basolateral membrane in normal epithelium, it is frequently found intracellularly localized in transformed cells. We have previously demonstrated the epithelial adaptor protein mucin 1 (MUC1) alters trafficking of EGFR, inhibiting its degradation and promoting its translocation to the nucleus, where it can directly modulate gene transcription. Here, we demonstrate that MUC1 promotes the retention of EGF-bound EGFR in Early Endosome Antigen1 (EEA1)-positive vesicles while preventing its trafficking to the lysosome. These events result in the accumulation of endosomal vesicles harboring active receptor throughout the cell and a reorganization of the actin cytoskeleton. EGF-dependent cell migration and filopodia formation is reliant upon this altered trafficking, and can be prevented by blocking retrograde trafficking. Together, these results indicate that intracellular EGFR may play an essential role in cancer metastasis and a potential mechanism for the failure of therapeutic antibodies in EGFR-driven metastatic breast cancer. PMID- 29464086 TI - SNP-array lesions in core binding factor acute myeloid leukemia. AB - Acute myeloid leukemia (AML) with t(8;21) and inv(16), together referred as core binding factor (CBF)-AML, are recognized as unique entities. Both rearrangements share a common pathophysiology, the disruption of the CBF, and a relatively good prognosis. Experiments have demonstrated that CBF rearrangements were insufficient to induce leukemia, implying the existence of cooperating events. To explore these aberrations, we performed single nucleotide polymorphism (SNP) array in a well-annotated cohort of 198 patients with CBF-AML. Excluding breakpoint-associated lesions, the most frequent events included loss of a sex chromosome (53%), deletions at 9q21 (12%) and 7q36 (9%) in patients with t(8;21) compared with trisomy 22 (13%), trisomy 8 (10%) and 7q36 deletions (12%) in patients with inv(16). SNP-array revealed novel recurrent genetic alterations likely to be involved in CBF-AML leukemogenesis. ZBTB7A mutations (20% of t(8;21) AML) were shown to be a target of copy-neutral losses of heterozygosity (CN-LOH) at chromosome 19p. FOXP1 focal deletions were identified in 5% of inv(16)-AML while sequence analysis revealed that 2% carried FOXP1 truncating mutations. Finally, CCDC26 disruption was found in both subtypes (4.5% of the whole cohort) and possibly highlighted a new lesion associated with aberrant tyrosine kinase signaling in this particular subtype of leukemia. PMID- 29464087 TI - 3D-Printed masks as a new approach for immobilization in radiotherapy - a study of positioning accuracy. AB - We developed a new approach to produce individual immobilization devices for the head based on MRI data and 3D printing technologies. The purpose of this study was to determine positioning accuracy with healthy volunteers. 3D MRI data of the head were acquired for 8 volunteers. In-house developed software processed the image data to generate a surface mesh model of the immobilization mask. After adding an interface for the couch, the fixation setup was materialized using a 3D printer with acrylonitrile butadiene styrene (ABS). Repeated MRI datasets (n=10) were acquired for all volunteers wearing their masks thus simulating a setup for multiple fractions. Using automatic image-to-image registration, displacements of the head were calculated relative to the first dataset (6 degrees of freedom). The production process has been described in detail. The absolute lateral (x), vertical (y) and longitudinal (z) translations ranged between -0.7 and 0.5 mm, 1.8 and 1.4 mm, and -1.6 and 2.4 mm, respectively. The absolute rotations for pitch (x), yaw (y) and roll (z) ranged between -0.9 and 0.8 degrees , -0.5 and 1.1 degrees , and -0.6 and 0.8 degrees , respectively. The mean 3D displacement was 0.9 mm with a standard deviation (SD) of the systematic and random error of 0.2 mm and 0.5 mm, respectively. In conclusion, an almost entirely automated production process of 3D printed immobilization masks for the head derived from MRI data was established. A high level of setup accuracy was demonstrated in a volunteer cohort. Future research will have to focus on workflow optimization and clinical evaluation. PMID- 29464088 TI - Deciphering microRNA targets in pancreatic cancer using miRComb R package. AB - MiRNAs are small non-coding RNAs that post-transcriptionally regulate gene expression. They play important roles in cancer but little is known about the specific functions that each miRNA exerts in each type of cancer. More knowledge about their specific targets is needed to better understand the complexity of molecular networks taking part in cancer. In this study we report the miRNA-mRNA interactome occurring in pancreatic cancer by using a bioinformatic approach called miRComb, which combines tissue expression data with miRNA-target prediction databases (TargetScan, miRSVR and miRDB). MiRNome and transcriptome of 12 human pancreatic tissues (9 pancreatic ductal adenocarcinomas and 3 controls) were analyzed by next-generation sequencing and microarray, respectively. Analysis confirmed differential expression of both miRNAs and mRNAs in cancerous tissue versus control, and unveiled 17401 relevant miRNA-mRNA interactions likely to occur in pancreatic cancer. They were sorted according to the degree of negative correlation between miRNA and mRNA expression. Results highlighted the importance of miR-148a and miR-21 interactions among others. Two components of the Notch signaling pathway, ADAM17 and EP300, were confirmed as miR-148a targets in MiaPaca-2 pancreatic cancer cells overexpressing miR-148a. Moreover, a CRISPR Cas9 cellular model was generated to knock-out the expression of miR-21 in PANC-1 cells. As expected, the expression of two miRComb miR-21 predicted targets, PDCD4 and BTG2, was significantly upregulated in these cells in comparison to control PANC-1. PMID- 29464089 TI - Cysts mark the early stage of metastatic tumor development in non-small cell lung cancer. AB - Identifying metastatic tumor growth at an early stage has been one of the biggest challenges in the treatment of lung cancer. By genetic lineage tracing approach in a conditional model of Non-Small Cell Lung Cancer (NSCLC) in mice, we demonstrate that cystic lesions represent an early stage of metastatic invasion. We generated a mouse model for NSCLC which incorporated a heritable DsRed fluorescent tag driven by the ubiquitous CAG promoter in the alveolar type II cells of the lung. We found early cystic lesions in a secondary organ (liver) that lacked the expression of bona fide lung makers namely Scgb1a1 and surfactant protein C Sftpc and were DsRed positive hence identifying lung as their source of origin. This demonstrates the significant potential of alveolar type II cells in orchestrating the process of metastasis, rendering it as one of the target cell types of the lung of therapeutic importance in human NSCLC. PMID- 29464090 TI - T cell infiltration into Ewing sarcomas is associated with local expression of immune-inhibitory HLA-G. AB - Ewing sarcoma (EwS) is an aggressive mesenchymal cancer of bones or soft tissues. The mechanisms by which this cancer interacts with the host immune system to induce tolerance are not well understood. We hypothesized that the non-classical, immune-inhibitory HLA-molecule HLA-G contributes to immune escape of EwS. While HLA-Gpos suppressor T cells were not increased in the peripheral blood of EwS patients, HLA-G was locally expressed on the tumor cells and/or on infiltrating lymphocytes in 16 of 47 pretherapeutic tumor biopsies and in 4 of 12 relapse tumors. HLA-G expression was not associated with risk-related patient variables or response to standard chemotherapy, but with significantly increased numbers of tumor-infiltrating CD3+ T cells compared to HLA-Gneg EwS biopsies. In a mouse model, EwS xenografts after adoptive therapy with tumor antigen-specific CAR T cells strongly expressed HLA-G whereas untreated control tumors were HLA-Gneg. IFN-gamma stimulation of EwS cell lines in vitro induced expression of HLA-G protein. We conclude that EwS cells respond to tumor-infiltrating T cells by upregulation of HLA-G, a candidate mediator of local immune escape. Strategies that modulate HLA-G expression in the tumor microenvironment may enhance the efficacy of cellular immunotherapeutics in this cancer. PMID- 29464091 TI - Boolean analysis identifies CD38 as a biomarker of aggressive localized prostate cancer. AB - The introduction of serum Prostate Specific Antigen (PSA) testing nearly 30 years ago has been associated with a significant shift towards localized disease and decreased deaths due to prostate cancer. Recognition that PSA testing has caused over diagnosis and over treatment of prostate cancer has generated considerable controversy over its value, and has spurred efforts to identify prognostic biomarkers to distinguish patients who need treatment from those that can be observed. Recent studies show that cancer is heterogeneous and forms a hierarchy of tumor cell populations. We developed a method of identifying prostate cancer differentiation states related to androgen signaling using Boolean logic. Using gene expression data, we identified two markers, CD38 and ARG2, that group prostate cancer into three differentiation states. Cancers with CD38-, ARG2- expression patterns, corresponding to an undifferentiated state, had significantly lower 10-year recurrence-free survival compared to the most differentiated group (CD38+ARG2+). We carried out immunohistochemical (IHC) staining for these two markers in a single institution (Stanford; n = 234) and multi-institution (Canary; n = 1326) cohorts. IHC staining for CD38 and ARG2 in the Stanford cohort demonstrated that combined expression of CD38 and ARG2 was prognostic. In the Canary cohort, low CD38 protein expression by IHC was significantly associated with recurrence-free survival (RFS), seminal vesicle invasion (SVI), extra-capsular extension (ECE) in univariable analysis. In multivariable analysis, ARG2 and CD38 IHC staining results were not independently associated with RFS, overall survival, or disease-specific survival after adjusting for other factors including SVI, ECE, Gleason score, pre-operative PSA, and surgical margins. PMID- 29464092 TI - mTOR inhibition enhances efficacy of dasatinib in ABL-rearranged Ph-like B-ALL. AB - High-risk subtypes of B-cell acute lymphoblastic leukemia (B-ALL) include Philadelphia chromosome-positive (Ph+) B-ALL driven by the BCR-ABL1 oncogene and a more recently identified subtype known as BCR-ABL-like or Ph-like B-ALL. A hallmark of both Ph+ and Ph-like B-ALL is constitutive activation of tyrosine kinase signaling that is potentially targetable with tyrosine kinase inhibitors (TKIs). B-ALL cells also receive extracellular signals from the microenvironment that can maintain proliferation and survival following treatment with TKIs. Therefore, there is strong rationale for combining TKIs with other therapies targeting signal transduction pathways. Here we show that combinations of the ABL directed TKI dasatinib with mTOR kinase inhibitors (TOR-KIs) are more effective than TKI alone against patient-derived Ph-like B-ALL cells harboring rearrangements of ABL1 or ABL2. We also report the establishment of a new human Ph-like B-ALL cell line that is stromal cell-independent in vitro and can be used for xenograft experiments in vivo. These findings provide rationale for clinical testing of TKI plus TOR-KIs in children and adults with Ph-like B-ALL and a new experimental tool to test promising therapeutic strategies in this poor prognosis subtype of B-ALL.

AB - Previous studies had suggested that Omega-3 fatty acids have pleiotropic effects and favourable safety profile, which may potentially increase the efficacy of antiarrhythmic drugs in suppressing atrial arrhythmias through combination therapy. This meta-analysis aimed to determine the effectiveness of using Omega-3 polyunsaturated fatty acids as a sole anti-arrhythmic agent or as an adjunct to existing pharmacological therapies in preventing atrial fibrillation recurrence. Randomized controlled trials published in English, from inception to December 2016, were considered. We searched for published studies in the following electronic databases: Cochrane Central Register of Controlled Trials, PubMed, EMBASE, Medline, Scopus, and Cumulative Index to Nursing and Allied Health Literature. Pooled hazard ratio (HR) and corresponding 95% confidence intervals (CI) for time to first atrial fibrillation recurrence was analysed using a fixed effects model. Four RCTs with 1,268 participants were included in the review. Our results showed that Omega-3 polyunsaturated fatty acid therapy had no effect on preventing atrial fibrillation recurrence compared to control/placebo group (HR: 1.13, 95% CI: 0.96 to 1.33, p = 0.14), with no significant heterogeneity found among those studies (Q value = 0.15, 9 = 0.99, I2 = 0%). Therefore, current evidence does not support treatment benefit of Omega-3 fatty acids in preventing atrial fibrillation recurrence among patients who have not been treated by any conventional reversion treatment, or who have only been treated with pharmacological therapy. PMID- 29464093 TI - Impact of LMP7 (rs2071543) gene polymorphism in increasing cancer risk: evidence from a meta-analysis and trial sequential analysis. AB - Genetic variant LMP7 (low molecular weight polypeptide 7) -145 C > A may influence the function of immune surveillance of an individual and lead to cancer development. Various studies have investigated the relevance of LMP7 -145 C > A gene polymorphism with cancer risk; but, their results are conflicting and inconsistent. To obtain a comprehensive conclusion, a meta-analysis was performed by including eight eligible published studies retrieved from PubMed (Medline), EMBASE and Google Scholar web search until December 2016. Individuals with AA genotype (AA vs CC: p = 0.001; OR = 2.602, 95% CI = 1.780 to 3.803) of LMP7 -145 C > A were found to have 2 folds higher risk of cancer than those with CC genotype. The recessive genetic model (AA vs AC + CC) also indicated that individuals with AA genotype have 2 folds higher cancer risk than AC and CC genotypes (p = 0.001; OR = 2.216, 95% CI = 1.525 to 3.221). Also, significant increased cancer risk was observed in Asians but not in Caucasians. No publication bias was observed during the analysis. Trial sequential analysis also strengthened our current findings. These results suggest that genetic variant LMP7-145 C > A has significant role in increasing cancer risk in overall and Asian population, and could be useful as a prognostic marker for early cancer predisposition. PMID- 29464095 TI - An integrated analysis of hyponatremia in cancer patients receiving platinum based or nonplatinum-based chemotherapy in clinical trials (JCOG1405-A). AB - Background: Hyponatremia is a common electrolyte abnormality in cancer patients who receive chemotherapy. Among anticancer agents, platinum-based agents are reported to cause chemotherapy-induced hyponatremia. However, the actual incidence and risk factors remain unknown. Results: The reports of 29 trials were analyzed. The incidence of grade 3/4 hyponatremia was 11.9% in patients treated with platinum-based chemotherapy and 3.8% in those treated with nonplatinum-based regimens (P < 0.01). Univariable analysis revealed a high incidence of hyponatremia in patients receiving cisplatin, three-drug combination regimen, two drug combination regimen with amrubicin or irinotecan, or high-dose cisplatin (weekly equivalent cisplatin dose >=20 mg/m2), and in patients with small-cell lung cancer. Conclusion: This is the first report of the actual incidence and the potential risk factors of chemotherapy-induced hyponatremia. Careful monitoring of serum sodium level is needed when platinum-based chemotherapy is administered. Methods: This study included all clinical trials of systemic chemotherapies for solid cancers that were conducted by the Japan Clinical Oncology Group (JCOG) after January 2000 and of which the patient enrolment was completed by January 2014. The latest reports of each trial were used for analysis. The incidence of chemotherapy-induced grade 3/4 hyponatremia and the potential risk factors were investigated with univariable analysis. PMID- 29464096 TI - A multicenter, retrospective analysis of elderly patients with acute myeloid leukemia who were treated with decitabine. AB - Decitabine is widely accepted as the treatment options for elderly acute myeloid leukemia (AML) patients. However, the efficacy has yet been assessed in Asian population. We retrospectively analyzed the outcomes of 80 Korean elderly AML patients who were treated with decitabine. The median age was 74 years (range, 64 to 86 years) and 6 (7.5%), 48 (60.0%), and 25 (31.3%) patients were categorized to favorable, intermediate, and poor risk group, respectively. The median OS was 10.2 months (95% CI 5.0-15.4). Given that decitabine treatment demonstrated improved clinical outcomes, it could be considered as one of the first-line treatment for Korean elderly AML patients. PMID- 29464097 TI - The association between hydroxychloroquine treatment and cardiovascular morbidity among rheumatoid arthritis patients. AB - Objectives: To examine the independent effect of hydroxychloroquine (HCQ) treatment on cardiovascular morbidity among RA patients. Materials and Methods: A retrospective cohort study of RA patients treated at Meir medical center between 2003-2013 was conducted. Patients were divided into two groups, those who had been treated with HCQ during the course of their disease and those who had never received it. The two groups were compared for possible confounding factors. Study endpoints included arterial and venous thrombotic events. Results: A total of 514 suitable RA patients were identified, 241 HCQ-treated and 273 non-treated patients. Of the HCQ-treated patients, 32 (13.3%) suffered from cardiovascular events compared to 104 (38.1%) of the non-treated group. HCQ treatment had a significant protective effect for all cardiovascular events examined (HR = 0.456 CI 0.287 to 0.726) as well as arterial events alone (HR = 0.461 CI 0.274 to 0.778). A dose of 400 mg HCQ per day demonstrated a protective effect for any cardiovascular event (HR = 0.432 CI 0.243 to 0.768), while the lower dose of 200 mg per day showed no significant protective effect. Conclusions: The use of HCQ is independently associated with decreased risk for cardiovascular morbidity among RA patients, particularly with a higher dose of 400 mg per day. This newly demonstrated effect of HCQ should be considered in the overall management of RA. PMID- 29464098 TI - Forty five percent of the Israeli population were infected with the influenza B Victoria virus during the winter season 2015-16. AB - While infection with influenza A viruses has been extensively investigated, infections with influenza B viruses which are commonly categorized into the highly homologous Victoria and Yamagata lineages, are less studied, despite their considerable virulence. Here we used RT-PCR assays, hemagglutination inhibition assays and antibody titers to determine the levels of influenza B infection. We report of high influenza B Victoria virus prevalence in the 2015-16 winter season in Israel, affecting approximately half of the Israeli population. We further show that the Victoria B virus infected individuals of all ages and that it was present in the country throughout the entire winter season. The vaccine however included the inappropriate Yamagata virus. We propose that a quadrivalent vaccine, that includes both Yamagata and Victoria lineages, should be considered for future influenza vaccination. PMID- 29464101 TI - Pneumatocele during sorafenib therapy: first report of an unusual complication. AB - Sorafenib is a multi-kinase inhibitor and a vascular endothelial growth factor (VEGF) inhibitor approved to treat patients with advanced hepatocellular carcinoma, renal cell carcinoma and differentiated thyroid carcinoma. Its most common side effects are asthenia/fatigue, skin toxicity, diarrhea and arterial hypertension. Reported respiratory adverse reactions include dyspnea, cough, pleural effusion and hoarseness. The aim of this report is to describe for the first time the occurrence of pneumatocele in two patients treated with Sorafenib. Patients had no respiratory symptoms and alternative diagnoses were ruled out. Primary tumors were different (liver metastases from a pancreatic neuroendocrine tumor and hepatocellular carcinoma) but both patients had been treated with yttrium 90 radioembolization 9 and 17 months before starting on Sorafenib, respectively. No complications occurred and Sorafenib withdrawal was followed by radiologic improvement. PMID- 29464100 TI - Pancreatic cancer: disease dynamics, tumor biology and the role of the microenvironment. AB - Pancreatic cancer is known for its propensity to metastasize. Recent studies have challenged the commonly held belief that pancreatic cancer is a stepwise process, where tumor cells disseminate late in primary tumor development. Instead it has been suggested that pancreatic tumor cells may disseminate early and develop independently and in parallel to the primary tumor. Circulating tumor cells can be found in most patients with pancreatic cancer, even in those with localized stage. Also, recent phylogenetic analyses have revealed evidence for a branched evolution where metastatic lineages can develop early in tumor development. In this Review, we discuss current models of pancreatic cancer progression and the importance of the tumor microenvironment, in order to better understand the recalcitrant nature of this disease. PMID- 29464099 TI - Implications of KRAS mutations in acquired resistance to treatment in NSCLC. AB - Rationale: KRAS is the most common and, simultaneously, the most ambiguous oncogene implicated in human cancer. Despite KRAS mutations were identified in Non Small Cell Lung Cancers (NSCLCs) more than 20 years ago, selective and specific inhibitors aimed at directly abrogating KRAS activity are not yet available. Nevertheless, many therapeutic approaches have been developed potentially useful to treat NSCLC patients mutated for KRAS and refractory to both standard chemotherapy and targeted therapies.The focus of this review will be to provide an overview of the network related to the intricate molecular KRAS pathways, stressing on preclinical and clinical studies that investigate the predictive value of KRAS mutations in NSCLC patients. Materials and Methods: A bibliographic search of the Medline database was conducted for articles published in English, with the keywords KRAS, KRAS mutations in non-small cell lung cancer, KRAS and tumorigenesis, KRAS and TKIs, KRAS and chemotherapy, KRAS and monoclonal antibody, KRAS and immunotherapy, KRAS and drugs, KRAS and drug resistance. PMID- 29464102 TI - Development of an Estimation Instrument of Acoustic Lens Properties for Medical Ultrasound Transducers. AB - In medical ultrasound transducers, the transmission mode (pass-through) approach has been used to estimate the characteristics of the acoustic lens. However, it is difficult to measure the acoustic lens properties with high precision because of human, systemic, or mechanical measurement errors. In this paper, we propose a low-cost estimation instrument for acoustic lens properties connected with a customized database. In the instrument, three-axis and one-axis transmitting and material fixtures accurately align the transmitting and receiving transducers separately. Through the developed instrument, we obtained a precise standard deviation of the attenuation coefficient and velocity of the acoustic lens material of 0.05 dB/cm and 2.62 m/s, respectively. Additionally, the simultaneous alignment between the fixtures is controllable with developed programs, thus generating very accurate information of the acoustic lens about the testing ultrasound transducer. In our instrument, the database could support users in managing the result data efficiently. User programs developed using LabVIEW provide the capability to obtain precise values of the attenuation coefficient and velocity, which represent the fundamental material characteristics of the acoustic lens of the medical ultrasound transducers. The developed review program of the customized database can also search the acoustic lens information and store the experimental results. PMID- 29464103 TI - Dehydration is how you define it: comparison of 318 blood and urine athlete spot checks. AB - : Clinical medicine defines dehydration using blood markers that confirm hypertonicity (serum sodium concentration ([Na+])>145 mmol/L) and intracellular dehydration. Sports medicine equates dehydration with a concentrated urine as defined by any urine osmolality (UOsm) >=700 mOsmol/kgH2O or urine specific gravity (USG) >=1.020. Objective: To compare blood versus urine indices of dehydration in a cohort of athletes undergoing routine screenings. Methods: 318 collegiate athletes (193 female) provided blood and urine samples and asked to rate how thirsty they were on a 10-point visual analogue scale. Serum was analysed for [Na+], while serum and UOsm were measured using an osmometer. USG was measured using a Chemstrip. Data were categorised into dehydrated versus hydrated groupings based on these UOsm and USG thresholds. Results: Using UOsm >=700 mOsmol/kgH2O to define dehydration, 55% of athletes were classified as dehydrated. Using any USG >=1.020 to define dehydration, 27% of these same athletes were classified as dehydrated. No athlete met the clinical definition for dehydration (hypertonicity; serum [Na+]>145 mmol/L). Normonatremia (serum [Na+] between 135 mmol/L and 145 mmol/L) was maintained in 99.7% of athletes despite wide variation in UOsm (110-1298 mOsmol/kgH2O). A significant correlation was confirmed between serum [Na+] versus UOsm (r=0.18; P<0.01), although urine concentration extremes did not reflect derangement in serum markers or thirst rating. Conclusion: Urine concentration thresholds classified 27%-55% of collegiate athletes as dehydrated, while no athlete was dehydrated according to blood [Na+] measurement. Practitioners should caution against using urine indices to diagnose or monitor dehydration, because urinary output is a response rather than a reflection of (tightly regulated) blood tonicity. PMID- 29464104 TI - Does ovulation affect performance in tennis players? AB - Background: Scientific data on the performance of collegiate female tennis players during the menstrual phases are scarce. Trial design: Double-blind, counter-balanced, crossover trials were conducted to examine whether tennis performance was affected during menstruation, with and without dehydroepiandrosterone sulfate (DHEA-S) supplementation. Methods: Ten Division 1 collegiate tennis players (aged 18-22 years) were evenly assigned into placebo supplemented and DHEA-supplemented (25 mg/day) trials. Treatments were exchanged among the participants after a 28-day washout. Tennis serve performance was assessed on the first day of menstrual bleeding (day 0/28) and on days 7, 14 and 21. Results: Mood state was unaltered during the menstrual cycles in both trials. The lowest tennis serve performance score (speed times accuracy) occurred on day 14 (P=0.06 vs day 0; P=0.01 vs day 21) in both placebo and DHEA trials. Decreased performance on day 14 was explained by decreased accuracy (P=0.03 vs day 0/28; P=0.01 vs day 21), but not velocity itself. Isometric hip strength, but not quadriceps strength, was moderately lower on day 14 (P=0.08). Increasing plasma DHEA-S (by ~65%) during the DHEA-supplemented trial had no effects on mood state, sleep quality or tennis serve performance. Conclusion: We have shown that menses does not affect serve performance of collegiate tennis players. However, the observed decrement in the accuracy of serve speed near ovulation warrants further investigation. PMID- 29464105 TI - Osteochondral defects of the talus with a focus on platelet-rich plasma as a potential treatment option: a review. AB - Objective: To provide a review of osteochondral lesions of the talus, to discuss the evidence of the risks and benefits of platelet-rich plasma (PRP) as a viable treatment option, and to measure the efficacy of PRP using MRI evidence of cartilage regeneration, as well as scales that measure improvement in 'pain' and 'functionality'. Eligibility criteria: Studies that use PRP in either conservative or intraoperative settings to treat osteochondral defects of the talus. Results: There are seven studies that compare hyaluronic acid or standard surgical options against PRP in treating osteochondral lesions of the talus. Five studies use PRP as supplemental treatment in intraoperative settings, while two studies use PRP conservatively as intra-articular injections. There were minimal adverse effects. Pain and functionality scores consistently improved in those who underwent PRP treatments over the course of 4 years. MRI showed significant but inconsistent results in chondral regeneration. Conclusion: PRP may show clinical benefit in those with osteochondral lesions of the talus in terms of pain and functionality, although chondral regeneration via MRI is inconsistent. Limitations include the small sample sizes in these seven studies, as well as no standardised formula for PRP preparation. Clinical relevance: To serve as an overview of the literature regarding PRP treatment for osteochondral lesions of the talus and how this modality may improve patient outcomes in pain, functionality and chondral regeneration. A case is reported to complement the subject review. PMID- 29464106 TI - Hospital-treated injuries from horse riding in Victoria, Australia: time to refocus on injury prevention? AB - Background: The most recent report on hospital-treated horse-riding injuries in Victoria was published 20 years ago. Since then, injury countermeasures and new technology have aimed to make horse riding safer for participants. This study provides an update of horse-riding injuries that required hospital treatment in Victoria and examines changes in injury patterns compared with the earlier study. Methods: Horse-riding injuries that required hospital treatment (hospital admission (HA) or emergency department (ED) presentations) were extracted from routinely collected data from public and private hospitals in Victoria from 2002 2003 to 2015-2016. Injury incidence rates per 100 000 Victorian population per financial year and age-stratified and sex-stratified injury incidence rates are presented. Poisson regression was used to examine trends in injury rates over the study period. Results: ED presentation and HA rates were 31.1 and 6.6 per 100 000 person-years, increasing by 28.8% and 47.6% from 2002 to 2016, respectively. Female riders (47.3 ED and 10.1 HA per 100 000 person-years) and those aged between 10 and 14 years (87.8 ED and 15.7 HA per 100 000 person-years) had the highest incidence rates. Fractures (ED 29.4%; HA 56.5%) and head injuries (ED 15.4%; HA 18.9%) were the most common injuries. HA had a mean stay of 2.6+/-4.1 days, and the mean cost per HA was $A5096+/-8345. Conclusion: Horse-riding injuries have remained similar in their pattern (eg, types of injuries) since last reported in Victoria. HA and ED incidence rates have increased over the last 14 years. Refocusing on injury prevention countermeasures is recommended along with a clear plan for implementation and evaluation of their effectiveness in reducing injury.

PMID- 29464109 TI - Global cancer control: responding to the growing burden, rising costs and inequalities in access. AB - The cancer burden is rising globally, exerting significant strain on populations and health systems at all income levels. In May 2017, world governments made a commitment to further invest in cancer control as a public health priority, passing the World Health Assembly Resolution 70.12 on cancer prevention and control within an integrated approach. In this manuscript, the 2016 European Society for Medical Oncology Leadership Generation Programme participants propose a strategic framework that is in line with the 2017 WHO Cancer Resolution and consistent with the principle of universal health coverage, which ensures access to optimal cancer care for all people because health is a basic human right. The time for action is now to reduce barriers and provide the highest possible quality cancer care to everyone regardless of circumstance, precondition or geographic location. The national actions and the policy recommendations in this paper set forth the vision of its authors for the future of global cancer control at the national level, where the WHO Cancer Resolution must be implemented if we are to reduce the cancer burden, avoid unnecessary suffering and save as many lives as possible. PMID- 29464110 TI - Phase I study of the investigational oral mTORC1/2 inhibitor sapanisertib (TAK 228): tolerability and food effects of a milled formulation in patients with advanced solid tumours. AB - Background: Sapanisertib (TAK-228) is an investigational, orally available, potent and highly selective mTORC1/2 inhibitor demonstrating promise in numerous malignancies. This phase I study (NCT02412722) evaluated the safety, tolerability, pharmacokinetics and antitumour activity of single-agent TAK-228 (milled capsules), administered daily (QD) or weekly (QW) and in combination with paclitaxel in patients with advanced solid tumours. Pharmacokinetic comparisons of milled versus unmilled TAK-228 and the impact of food were also investigated. Methods: Patients were enrolled to receive: TAK-228 QD, TAK-228 3 days/week plus paclitaxel 80 mg/m2 days 1, 8, 15 (TAK-228+P) or TAK-228 QW (all 28-day cycles); starting TAK-228 doses were 4, 6 and 20 mg, respectively. Results: Sixty-one adults were enrolled. Maximum tolerated doses for milled TAK-228 were 3 mg (TAK 228 QD), 6 mg (TAK-228+P) and 30 mg (TAK-228 QW). Most patients reported >=1 adverse event (AE); there were no meaningful differences in drug-related AEs across regimens or doses. Three on-study deaths occurred, all considered unrelated to study drugs. TAK-228 pharmacokinetics did not differ between unmilled/milled capsules or with/without paclitaxel. However, TAK-228 Cmax decreased by ~40% in fed versus fasted patients. Objective response rates were 12% (TAK-228 QD), 18% (TAK-228+P) and 0% (TAK-228 QW). One patient receiving TAK 228+P had a complete response; three patients receiving TAK-228+P and two patients receiving TAK-228 QD had partial responses. Conclusions: Milled TAK-228 was well tolerated with signs of antitumour activity; administration did not reduce overall exposure (area under the plasma concentration-time curve) but reduced Cmax, which is expected when dosed in the fed state. These promising findings warrant further investigation. Trial registration number: NCT02412722.

PMID- 29464112 TI - Phase I study of tomuzotuximab, a glycoengineered therapeutic antibody against the epidermal growth factor receptor, in patients with advanced carcinomas. AB - Background: Changes in glycosylation of the constant domain (Fc) of monoclonal antibodies (mAbs) enhance antibody-dependent cell-mediated cytotoxicity independently of downstream effects following receptor blockade by the antibody, thus extending their indication. We investigated the safety, pharmacokinetics, pharmacodynamics and antitumour activity of tomuzotuximab, an IgG1 glycoengineered mAb against the epidermal growth factor receptor with enhanced tumour cytotoxicity in a phase I dose-escalation study (NTC01222637). Patients and methods: Forty-one patients with advanced solid tumours refractory to standard therapies received tomuzotuximab weekly (12-1370 mg) or two-weekly (990 mg) on a three-plus-three dose escalation design. Results: A maximum tolerated dose was not reached. The most frequent treatment-related adverse events were infusion-related reactions in 31 (76%) patients (grade 3, 12%), mainly confined to the first dose, and skin toxicities (grade 1 or 2) in 30 (73%) patients. Hypomagnesaemia was observed in 9 out of 23 evaluable patients (39%). Similar to cetuximab, tomuzotuximab concentrations increased proportionally to dose from doses>=480 mg with a median terminal half life (t1/2) of 82 hours, range 55-113 hours. Antitumour activity included one complete response ongoing since more than 4.5 years in a patient with non-small-cell lung cancer and one partial response lasting 353 days in a patient with colorectal cancer. Twelve patients achieved stable disease (median, 166 days, range, 71-414 days) and two patients had prolonged control (>1 year) of their non-measurable disease. Conclusion: Tomuzotuximab was safe and showed promising antitumour activity in heavily pretreated patients with advanced metastatic disease. A phase IIb trial of chemotherapy and weekly tomuzotuximab or cetuximab followed with maintenance therapy with the corresponding mAb in patients with recurrent or metastatic head and neck squamous cell carcinoma is ongoing. PMID- 29464114 TI - Primary Outcomes of Accelerated Epithelium-Off Corneal Cross-Linking in Progressive Keratoconus in Children: A 1-Year Prospective Study. AB - Purpose: To evaluate corneal transparency following accelerated collagen cross linking (ACXL) in pediatric keratoconus. Design: A prospective interventional case series. Methods: This study included 47 eyes (25 patients), aged 9-14 years, with documented progressive keratoconus. After applying 0.1% riboflavin drops, ACXL was performed. Assessment included corrected distance visual acuity (CDVA), uncorrected visual acuity (UCVA), corneal haze, and corneal densitometry in grayscale units (GSU). Result: The mean baseline and corneal densitometry peaked at 3 months post-ACXL while central and posterior densitometry showed a statistically significant increase (P < 0.05) and peaked at 8 months postoperatively. By 12 months, densitometry in all corneal layers (P >= 0.99) and concentric zones (P >= 0.97) reached near baseline values. Slit-lamp graded haze peaked at 1 month to 1.82 +/- 0.65 (P < 0.05) and declined to near baseline at 12 months (0.39 +/- 0.58). There was a statistically significant increase in the mean UCVA and CDVA at 12 months. Conclusion: Total and anterior corneal densitometry peaked after 3 months, while central and posterior densitometry peaked after 8 months. Maximum haze was at 1 month post-ACXL. All corneal layers, concentric zone densitometry and haze reached near baseline values after 1 year. Scheimpflug densitometry showed weak correlation with CDVA over the 12-month follow-up period (r = -0.193). PMID- 29464115 TI - Ocular Biometry in Primary Angle-Closure Glaucoma Associated with Retinitis Pigmentosa. AB - Background: Retinitis pigmentosa (RP) comprises a group of inherited disorders in which patients typically lose night vision in adolescence and then lose peripheral vision in young adulthood before eventually losing central vision later in life. A retrospective case-control study was performed to evaluate differences in ocular biometric parameters in primary angle-closure glaucoma (PACG) patients with and without concomitant RP to determine whether a relationship exists between PACG and RP. Methods: We used ultrasound biomicroscopy (UBM) to measure anterior chamber depth (ACD). A-scan biometry was carried out to measure lens thickness (LT) and axial length (AL). Propensity score matching and mixed linear regression model analysis were conducted. 23 patients with chronic primary angle-closure glaucoma (CPACG) associated with RP, 21 patients with acute primary angle-closure glaucoma (APACG) associated with RP, 270 patients with CPACG, and 269 patients with APACG were recruited for this study. Results: There were no significant differences on ACDs, ALs, and relative lens position (RLP) (P > 0.05) between patients with PACG associated with RP and patients with PACG; however, patients with APACG associated with RP had a significantly greater LT than patients with APACG (P < 0.05). Conclusion: Patients with PACG associated with RP had the same biometric parameter characteristic as the patients with CPACG and APACG. This may suggest that RP is a coincidental relationship with angle-closure glaucoma. PMID- 29464116 TI - Putative HIV and SIV G-Quadruplex Sequences in Coding and Noncoding Regions Can Form G-Quadruplexes. AB - The HIV virus is one of the most studied viruses in the world. This is especially true in terms of gene sequencing, and to date more than 9 thousand genomic sequences of HIV isolates have been sequenced and analyzed. In this study, a series of DNA sequences, which have the potential to form G-quadruplex structures, is analyzed. Several such sequences were found in various coding and noncoding virus domains, including the U3 LTR, tat, rev, env, and vpx regions. Interestingly, a homological sequence to the already well-known HIV integrase aptamer was identified in the minus-strand. The sequences derived from original isolates were analyzed using standard spectral and electrophoretic methods. In addition, a recently developed methodology is applied which uses induced circular dichroism spectral profiles of G-quadruplex-ligand (Thiazole Orange) complexes to determine if G-rich sequences can adopt G-quadruplex structure. Targeting the G quadruplexes or peptide domains corresponding to the G-rich coding sequence in HIV offers researchers attractive therapeutic targets which would be of particular use in the development of novel antiviral therapies. The analysis of G rich regions can provide researchers with a path to find specific targets which could be of interest for specific types of virus. PMID- 29464117 TI - Metabolomic Insights into the Nutritional Status of Adults and Adolescents with Phenylketonuria Consuming a Low-Phenylalanine Diet in Combination with Amino Acid and Glycomacropeptide Medical Foods. AB - Background: Nutrient status in phenylketonuria (PKU) requires surveillance due to the restrictive low-Phe diet in combination with amino acid medical foods (AA-MF) or glycomacropeptide medical foods (GMP-MF). Micronutrient profiles of medical foods are diverse, and optimal micronutrient supplementation in PKU has not been established. Methods: In a crossover design, 30 participants with PKU were randomized to consume AA-MF and GlytactinTM GMP-MF in combination with a low-Phe diet for 3 weeks each. Fasting venipunctures, medical food logs, and 3-day food records were obtained. Metabolomic analyses were completed in plasma and urine by Metabolon, Inc. Results: The low-Phe diets in combination with AA-MF and GMP-MF were generally adequate based on Dietary Reference Intakes, clinical measures, and metabolomics. Without micronutrient supplementation of medical foods, >70% of participants would have inadequate intakes for 11 micronutrients. Despite micronutrient supplementation of medical foods, inadequate intakes of potassium in 93% of participants and choline in >40% and excessive intakes of sodium in >63% of participants and folic acid in >27% were observed. Sugar intake was excessive and provided 27% of energy. Conclusions: Nutrient status was similar with AA-MF and Glytactin GMP-MF. More research related to micronutrient supplementation of medical foods for the management of PKU is needed. PMID- 29464118 TI - Health Behaviour among Nurses Working in Public Hospitals in Kakamega County, Kenya. AB - Health behaviour refers to actions undertaken by a person who perceives self to be ill for the purpose of finding an appropriate remedy. Nurses as gate keepers of health are expected to seek formal treatment when they are taken ill because this is what they teach their patients. Nurses' working conditions all over the world are described as squalid with long working hours and workload. This scenario predisposes them to occupational health hazards and at the same time denies them time for self-care. Although nurses are knowledgeable about disease and its treatment and have access to health care, they engage in self-treatment in contrast to what they teach patients. Health behaviour among nurses in Kakamega County was investigated using a cross-sectional design. Data was collected using self-administered questionnaires and subjected to bivariate and logistic regression analyses. The study found that health behaviour of nurses in Kakamega County is below expectation, as 33% (n = 61) engaged in voluntary screening services. Further, 34.8% (n = 65) said that their health would improve if they engaged in health promotion activities. The study recommends empowering nurses to engage in positive health behaviour through education. The county should also provide affordable screening services to its nurses. PMID- 29464119 TI - Instrumental Mechanoreceptoric Palpation in Gastrointestinal Surgery. AB - Background and Aims: Small gastric or colorectal tumours can be visually undetectable during laparoscopic surgeries, and available methods still do not provide a 100% localisation rate. Thus, new methods for further improvements in tumour localisation are highly desirable. In this study, we evaluated the usage of the Medical Tactile Endosurgical Complex (MTEC) in gastrointestinal surgery for localisation of tumours. The MTEC provides the possibility of instrumental mechanoreceptoric palpation, which serves as an analogue of conventional manual palpation. Methods: Ninety-six elective surgeries were performed, including 48 open surgeries, 43 laparoscopies, and 5 robot-assisted surgeries. The 20 mm version of the MTEC tactile mechanoreceptor was used in open surgeries, and the 10 mm version in laparoscopic and robot-assisted surgeries. Results: The mean time of instrumental mechanoreceptoric palpation was 3 minutes 12 seconds for open surgeries, which constituted the early stage of the learning curve, and 3 minutes 34 seconds for laparoscopic surgeries. No side effects or postoperative complications related to instrumental mechanoreceptoric palpation were observed, and this procedure provided data sufficient for tumour localisation in more than 95% of cases. Conclusion: Instrumental mechanoreceptoric palpation performed using MTEC is a simple, safe, and reliable method for tumour localisation in gastrointestinal laparoscopic surgery.

AB - Background: Congenital adrenal hyperplasia (CAH) is an endocrine condition that requires regularly blood samples for optimal treatment. The management of CAH in children is complex when intravenous access is one of the most stressful procedures for children. The purpose of this pilot study was to investigate the effects of nitrous oxide inhalation (N2O) in combination with cutaneous application of local anesthetics (EMLA) for improving intravenous access in children with CAH. Method: Ten children (7-14 years) were studied. The children received two intravenous procedures: one with EMLA and one with EMLA + N2O. The order of priority was randomized. The outcomes were the children's pain experience (0-10) and an evaluation of satisfaction (1-5) after the procedure. Heart rate, blood pressure, saturation, and analyses of 17-hydroxyprogesterone (17-OHP), norepinephrine, and glucose were analyzed. Results: Higher pain scores, heart rate, and glucose levels were reported after EMLA, compared to EMLA + N2O, but 17-OHP levels remained unchanged. The children's satisfaction with the intravenous procedure was more positive for EMLA + N2O. Conclusions: EMLA + N2O offers the possibility of improving the intravenous procedure for anxious children with CAH. Although the quality of care was better with N2O treatment, it was not possible to demonstrate that this is a prerequisite for valid 17-OHP measurements. PMID- 29464121 TI - Interaction Effects of Season of Birth and Cytokine Genes on Schizotypal Traits in the General Population. AB - Literature suggests that the effect of winter birth on vulnerability to schizophrenia might be mediated by increased expression of proinflammatory cytokines due to prenatal infection and its inadequate regulation by anti inflammatory factors. As the response of the immune system depends on genotype, this study assessed the interaction effects of cytokine genes and season of birth (SOB) on schizotypy measured with the Schizotypal Personality Questionnaire (SPQ 74). We searched for associations of IL1B rs16944, IL4 rs2243250, and IL-1RN VNTR polymorphisms, SOB, and their interactions with the SPQ-74 total score in a sample of 278 healthy individuals. A significant effect of the IL4 X SOB interaction was found, p = 0.007 and eta2 = 0.028. We confirmed this effect using an extended sample of 373 individuals. Homozygotes CC born in winter showed the highest SPQ total score and differed significantly from winter-born T allele carriers, p = 0.049. This difference was demonstrated for cognitive-perceptual and disorganized but not interpersonal dimensions. The findings are consistent with the hypothesis that the cytokine genes by SOB interaction can influence variability of schizotypal traits in the general population. The IL4 T allele appeared to have a protective effect against the development of positive and disorganized schizotypal traits in winter-born individuals. PMID- 29464122 TI - The Use of BEREP4 Immunohistochemistry Staining for Detection of Basal Cell Carcinoma. AB - Basal Cell Carcinoma (BCC) is the most common type of malignant cancer found in the world today with a 3-10% increase in incidence each year. The American Cancer Society reported that 8 out of 10 patients with skin cancer are suffering from BCC with over 2 million new cases each year. BCC needs to be detected at the early stages to prevent local destruction causing disabilities to patients and increasing treatment costs. Furthermore, BCC patients who have undergone surgery are still at risk for recurrence, especially when the surgery performed fails to remove all the BCC cells, even when conventional histopathological testing after surgery has reported a surgically free margin. This review aims to evaluate studies on the use of BerEP4 immunohistochemistry staining on pathological sections of various types of BCC as well as its shortfalls. BerEP4 is a monoclonal antibody which detects specific epithelial-glycoprotein-adhesion molecules (EpCAM) found on BCC cells. Various studies have shown that BerEP4 has a high sensitivity and specificity in detecting only BCC cells. The use of BerEP4 immunohistochemistry testing for the routine examination of cases of BCC is expected to be able to increase and improve early diagnosis as well as prevent recurrence after surgery. PMID- 29464124 TI - Epstein-Barr Virus as a Promising Immunotherapeutic Target for Nasopharyngeal Carcinoma Treatment. AB - Epstein-Barr virus (EBV) is a pathogen that infects more than 90% of global human population. EBV primarily targets B-lymphocytes and epithelial cells while some of them infect monocyte/macrophage, T-lymphocytes, and dendritic cells (DCs). EBV infection does not cause death by itself but the infection has been persistently associated with certain type of cancers such as nasopharyngeal carcinoma (NPC), Burkitt's lymphoma (BL), and Hodgkin's lymphoma (HL). Recent findings have shown promise on targeting EBV proteins for cancer therapy by immunotherapeutic approach. Some studies have also shown the success of adopting EBV-based therapeutic vaccines for the prevention of EBV-associated cancer particularly on NPC. In-depth investigations are in progress to refine the current therapeutic and vaccination strategies. In present review, we discuss the highly potential EBV targets for NPC immunotherapy and therapeutic vaccine development as well as addressing the underlying challenges in the process of bringing the therapy and vaccination from the bench to bedside. PMID- 29464123 TI - Targeted Therapeutic Nanoparticles: An Immense Promise to Fight against Cancer. AB - In nanomedicine, targeted therapeutic nanoparticle (NP) is a virtual outcome of nanotechnology taking the advantage of cancer propagation pattern. Tying up all elements such as therapeutic or imaging agent, targeting ligand, and cross linking agent with the NPs is the key concept to deliver the payload selectively where it intends to reach. The microenvironment of tumor tissues in lymphatic vessels can also help targeted NPs to achieve their anticipated accumulation depending on the formulation objectives. This review accumulates the application of poly(lactic-co-glycolic acid) (PLGA) and polyethylene glycol (PEG) based NP systems, with a specific perspective in cancer. Nowadays, PLGA, PEG, or their combinations are the mostly used polymers to serve the purpose of targeted therapeutic NPs. Their unique physicochemical properties along with their biological activities are also discussed. Depending on the biological effects from parameters associated with existing NPs, several advantages and limitations have been explored in teaming up all the essential facts to give birth to targeted therapeutic NPs. Therefore, the current article will provide a comprehensive review of various approaches to fabricate a targeted system to achieve appropriate physicochemical properties. Based on such findings, researchers can realize the benefits and challenges for the next generation of delivery systems. PMID- 29464126 TI - Thrombosis in the Surgically Corrected Anomalous Right Coronary Artery after Reimplantation in Aorta. AB - A 32-year-old African American female presented with dyspnea, and after several cardiac diagnostic tests, the diagnosis of an anomalous origin of the RCA from the pulmonary trunk was established by multislice coronary CT angiography. She underwent surgical correction with reimplantation of the RCA, from the pulmonary artery to the aortic root. However, 10 days after surgery, she developed frequent episodes of chest pain, and repeat coronary CTA showed a partially occlusive thrombus in the surgically reimplanted RCA. Anticoagulation with warfarin resulted in complete resolution of the patient's symptoms. PMID- 29464125 TI - Botanicals as Modulators of Neuroplasticity: Focus on BDNF. AB - The involvement of brain-derived neurotrophic factor (BDNF) in different central nervous system (CNS) diseases suggests that this neurotrophin may represent an interesting and reliable therapeutic target. Accordingly, the search for new compounds, also from natural sources, able to modulate BDNF has been increasingly explored. The present review considers the literature on the effects of botanicals on BDNF. Botanicals considered were Bacopa monnieri (L.) Pennell, Coffea arabica L., Crocus sativus L., Eleutherococcus senticosus Maxim., Camellia sinensis (L.) Kuntze (green tea), Ginkgo biloba L., Hypericum perforatum L., Olea europaea L. (olive oil), Panax ginseng C.A. Meyer, Rhodiola rosea L., Salvia miltiorrhiza Bunge, Vitis vinifera L., Withania somnifera (L.) Dunal, and Perilla frutescens (L.) Britton. The effect of the active principles responsible for the efficacy of the extracts is reviewed and discussed as well. The high number of articles published (more than one hundred manuscripts for 14 botanicals) supports the growing interest in the use of natural products as BDNF modulators. The studies reported strengthen the hypothesis that botanicals may be considered useful modulators of BDNF in CNS diseases, without high side effects. Further clinical studies are mandatory to confirm botanicals as preventive agents or as useful adjuvant to the pharmacological treatment. PMID- 29464127 TI - Use of High-Flow Nasal Cannula Oxygen Therapy in a Pregnant Woman with Dermatomyositis-Related Interstitial Pneumonia. AB - A 33-year-old pregnant woman was referred to our hospital with respiratory distress at 30 weeks of gestation. Chest computed tomography (CT) scans revealed pulmonary infiltrates along the bronchovascular bundles and ground-glass opacities in both lungs. Despite immediate treatment with steroid pulse therapy for suspected interstitial pneumonia, the patient's condition worsened. Respiratory distress was slightly alleviated after the initiation of high-flow nasal cannula (HFNC) oxygen therapy (40 L/min, FiO2 40%). We suspected clinically amyopathic dermatomyositis (CADM) complicating rapidly progressive refractory interstitial pneumonia. In order to save the life of the patient, the use of combination therapy with immunosuppressants was necessary. The patient underwent emergency cesarean section and was immediately treated with immunosuppressants while continuing HFNC oxygen therapy. The neonate was treated in the neonatal intensive care unit. The patient's condition improved after 7 days of hospitalization; by this time, she was positive for myositis-specific autoantibodies and was diagnosed with interstitial pneumonia preceding dermatomyositis. This condition can be potentially fatal within a few months of onset and therefore requires early combination immunosuppressive therapy. This case demonstrates the usefulness of HFNC oxygen therapy for respiratory management as it negates the need for intubation and allows for various treatments to be quickly performed. PMID- 29464128 TI - Perianal Comedones: A Rare Incidental Finding. AB - Comedones occur when an overproliferation of keratinocytes blocks sebum secretion in a pilosebaceous duct. Comedones have multiple possible etiologies and contributing factors. While comedones are common to acne, they are also seen in occupational exposures and are associated with certain syndromes. We describe a particularly rare case of comedones at the perianus that is not associated with any known exposure or disease and is a rare incidental finding. PMID- 29464129 TI - A Peculiar Case of Invasive Streptococcus pneumoniae. AB - Patients commonly present to the emergency department with acute respiratory distress; however, the differentials are broad and at times difficult to distinguish. We describe a case of severe community-acquired pneumonia (CAP) secondary to invasive Streptococcus pneumoniae. The patient was intubated within 3 h of presentation and suffered multiorgan failure within 72 h of intensive care unit (ICU) admission. This case is a stark illustration of how the most common bacteria associated with CAP can be fatal and highlights the associated markers of severity. It also outlines other potential complications including a very rare phenomenon of cardiomyopathy with myocarditis associated with S. pneumoniae bacteraemia. PMID- 29464130 TI - Osteoid Osteoma of the Trapezium: Case Report of an Unusual Tumor Location Presenting a Diagnostic Challenge. AB - Osteoid osteoma is a benign bone tumor, which represents approximately 10% of all benign bone tumors. When localized to the carpus, osteoid osteomas are most often seen in the scaphoid and capitate. Rarely, these tumors can also be observed in the trapezium. Given the infrequency with which osteomas are located in the trapezium and often nonspecific presenting symptoms, diagnosis of this tumor can be challenging and requires a high index of suspicion. PMID- 29464131 TI - Nutritional Aspects of Bone Health and Fracture Healing. AB - Introduction: Fractures are quite common, especially among the elderly. However, they can increase in prevalence in younger ages too if the bone health is not good. This may happen as a result of bad nutrition. Methods: A customized, retrospective review of available literature was performed using the following keywords: bone health, nutrition, and fractures. Results: Insufficient intake of certain vitamins, particularly A and D, and other nutrients, such as calcium, may affect bone health or even the time and degree of bone healing in case of fracture. The importance of different nutrients, both dietary and found in food supplements, is discussed concerning bone health and fracture healing. Conclusion: A healthy diet with adequate amounts of both macro- and micronutrients is essential, for both decreasing fracture risk and enhancing the healing process after fracture. PMID- 29464132 TI - Crowd-sourced Ontology for Photoleukocoria: Identifying Common Internet Search Terms for a Potentially Important Pediatric Ophthalmic Sign. AB - Purpose: Leukocoria is the most common presenting sign for pediatric eye disease including retinoblastoma and cataract, with worse outcomes if diagnosis is delayed. We investigated whether individuals could identify leukocoria in photographs (photoleukocoria) and examined their subsequent Internet search behavior. Methods: Using a web-based questionnaire, in this cross-sectional study we invited adults aged over 18 years to view two photographs of a child with photoleukocoria, and then search the Internet to determine a possible diagnosis and action plan. The most commonly used search terms and websites accessed were recorded. Results: The questionnaire was completed by 1639 individuals. Facebook advertisement was the most effective recruitment strategy. The mean age of all respondents was 38.95 +/- 14.59 years (range, 18-83), 94% were female, and 59.3% had children. An abnormality in the images presented was identified by 1613 (98.4%) participants. The most commonly used search terms were: "white," "pupil," "photo," and "eye" reaching a variety of appropriate websites or links to print or social media articles. Conclusions: Different words or phrases were used to describe the same observation of photoleukocoria leading to a range of websites. Variations in the description of observed signs and search words influenced the sites reached, information obtained, and subsequent help-seeking intentions. Translational Relevance: Identifying the most commonly used search terms for photoleukocoria is an important step for search engine optimization. Being directed to the most appropriate websites informing of the significance of photoleukocoria and the appropriate actions to take could improve delays in diagnosis of important pediatric eye disease such as retinoblastoma or cataract. PMID- 29464133 TI - Reduced Time to Breast Cancer Diagnosis with Coordination of Radiological and Clinical Care. AB - Introduction Diagnostic delays for breast problems is a current concern in British Columbia and diagnostic pathways for breast cancer are currently under review. Breast centres have been introduced in Europe and reported to facilitate diagnosis and treatment. Guidelines for breast centers are outlined by the European Society for Mastology (EUSOMA). A Rapid Access Breast Clinic (RABC) was developed at our hospital applying the concept of triple evaluation for all patients and navigation between clinicians and radiologists. We hypothesize that the Rapid Access Breast Clinic will decrease wait times to diagnosis and minimize duplication of services compared to usual care. Methods A retrospective review was undertaken looking at diagnostic wait times and the number of diagnostic centres involved for consecutive patients seen by breast surgeons with diagnostic workups performed either in the traditional system (TS) or the RABC. Only patients presenting with a new breast problem were included in the study. Results Patients seen at the RABC had a decreased time to surgical consultation (33 vs 86 days, p<0.0001) for both malignant (36 vs 59 days, p=0.0007) and benign diagnoses (31 vs 95 days, p<0.0001). Furthermore, 13% of the patients referred to the surgeon in the TS without a diagnosis were eventually diagnosed with a malignancy and waited a mean of 84 days for initial surgical assessment. Of the patients seen at the RABC, 5% required investigation at more than one institution compared to 39% patients seen in the TS (p<0.0001). Cancer patients had a shorter time from presentation to surgery in the RABC (64 vs 92 days, p=0.009). Conclusion The establishment of the RABC has significantly reduced the time to surgical consultation, time to breast cancer surgery, and duplication of investigations for patients with benign and malignant breast complaints. It is feasible to introduce a EUSOMA-based breast clinic in the Canadian Health Care System and improvements in diagnostic wait times are seen. We recommend the expansion of coordinated care to other sites. PMID- 29464134 TI - Crowdsourced Curriculum Development for Online Medical Education. AB - In recent years online educational content, efforts at quality appraisal, and integration of online material into institutional teaching initiatives have increased. However, medical education has yet to develop large-scale online learning centers. Crowd-sourced curriculum development may expedite the realization of this potential while providing opportunities for innovation and scholarship. This article describes the current landscape, best practices, and future directions for crowdsourced curriculum development using Kern's framework for curriculum development and the example topic of core content in emergency medicine. A scoping review of online educational content was performed by a panel of subject area experts for each step in Kern's framework. Best practices and recommendations for future development for each step were established by the same panel using a modified nominal group consensus process. The most prevalent curriculum design steps were (1) educational content and (2) needs assessments. Identified areas of potential innovation within these steps included targeting gaps in specific content areas and developing underrepresented instructional methods. Steps in curriculum development without significant representation included (1) articulation of goals and objectives and (2) tools for curricular evaluation. By leveraging the power of the community, crowd-sourced curriculum development offers a mechanism to diffuse the burden associated with creating comprehensive online learning centers. There is fertile ground for innovation and scholarship in each step along the continuum of curriculum development. Realization of this paradigm's full potential will require individual developers to strongly consider how their contributions will align with the work of others. PMID- 29464135 TI - Impact of CyberKnife Radiosurgery on Median Overall Survival of Various Parameters in Patients with 1-12 Brain Metastases. AB - Introduction This study's objective is to assess various patient, tumor and imaging characteristics and to compare median overall survival (OS) of 150 patients with 1-12 brain metastases post-CyberKnife radiosurgery (CKRS) (Accuray, Sunnyvale, California) alone. Methods Charts of 150 patients, from 2009-2014, treated with only CKRS for brain metastases were reviewed retrospectively for patient, tumor, and imaging characteristics. Parameters included demographics, Eastern Cooperative Oncology Group (ECOG) performance scores, number and control of extracranial disease (ECD) sites, cause of death (COD), histology, tumor volume (TV), and post-CKRS whole brain radiotherapy (WBRT). The imaging characteristics assessed were time of complete response (CR), partial response (PR), stable imaging or local failure (LF), and distal brain failure (DBF). The primary tumor Ki-67s of the breast carcinoma brain metastasis patients, who had the longest median OS of any group, were recorded when available. Results The predominant age group for the 150-patient cohort was the younger 17-65 years of age category, which was represented by 94 (62.7%). The 150-patient group had slightly more males, 79 (52.7%). The majority of 111 (74%) patients had an ECOG score of 1, 39 (26%) had 1 ECD site and uncontrolled ECD occurred in 112 (74.7%). The main COD was ECD in 106 (70.7%). The prevalent tumor histology was non-small cell lung carcinoma (88 of 150, 58.7%). The most common TV was 0-0.5 ccs (48 of 150, 32%). The majority of 125 (83.3%) patients did not undergo post-CKRS WBRT. Imaging outcomes were local control (LC) (CR, PR, or stable imaging) in 119 (79.3%), of whom 38 (25.3%) had CR, 56 (37.3%) PR and 25 (16.7%) stable imaging; LF was the outcome in 31 (20.7%) and DBF occured in 83 (55.3%). The median OS was 13 months. Patients 17-65 years of age had a median OS of 13 months, while those 66-88 years, had 12 months. Females versus males had median OS of 15 versus 12 months. The most prolonged median OS of 21.5 months occurred in those with an ECOG score of 0. Patients with two ECD sites had a median OS of 14.5 months, while those with controlled ECD, 20.5 months. Patients with breast cancer brain metastases had the longest median OS of 23 months. The median OS for each of three (0-0.5 ccs, 0.6-1.5 ccs, 1.6-4.0 ccs) of four CKRS TV quartiles was 13 months and for those with 4.1-28.5 ccs, 10 months. Median OS for patients with versus without post-CKRS WBRT was 23 versus 12 months. The longest median OS of 18.5 months for post-CKRS imaging outcomes was in patients with CR; those with LF had a median OS of 11.5 months. Of nine patients with breast carcinoma brain metastases with available Ki-67s from primary tumor resections, the Ki-67 values were >= 34% for four patients with CR, PR and stable imaging outcomes, and < 34% for five patients with LF. Conclusions An ECOG score of 0, ECD control, breast carcinoma brain metastasis histology. undergoing WBRT post-CKRS and CR imaging outcomes, each resulted in a longer median OS. The Ki-67 proliferation indices from primary breast carcinoma resection correlated well with the brain imaging outcomes in a small preliminary study in the present study's breast carcinoma patients with brain metastases. PMID- 29464136 TI - Anesthetic Management of Pheochromocytoma Resection in Adults with Single Ventricle Physiology. AB - Survival rates for patients with palliated congenital heart disease are increasing, and an increasing number of adults with cyanotic congenital heart disease (CCHD) might require surgical resection of pheochromocytoma-paraganglioma (PHEO-PGL). A recent study supports the idea that patients with a history of CCHD and current or historical cyanosis might be at increased risk for developing PHEO PGL. We review the anesthetic management of two adults with single-ventricle physiology following Fontan palliation presenting for PHEO-PGL resection and review prior published case reports. We found the use of epidural analgesia to be safe and effective in the operative and postoperative management of our patients. PMID- 29464137 TI - Podcast Use in Undergraduate Medical Education. AB - Introduction Podcasts have become increasingly popular as a medium for free open access medical education (FOAM). However, little research has examined the use of these extracurricular audio podcasts as tools in undergraduate medical education. We aimed to examine knowledge retention, usage conditions, and preferences of undergraduate medical students at a Canadian university interacting with extracurricular podcasts. Methods Students enrolled in the undergraduate medical program at McMaster University volunteered to participate in this study. Two podcasts were created specifically for the purposes of this study, and online tests and surveys were sent to participants to gather data regarding user preferences of podcasts. In addition, we recorded changes in topic test scores before and after podcast exposure. Results Forty-two students were recruited to this study. Participants who completed the assessments demonstrated an effect of learning. Podcasts of 30 minutes or less were preferred in the majority of participants who had a preference in duration. The top three activities participants were engaged in while listening to the podcasts were driving (46%), completing chores (26%), and exercising (23%). A large number of participants who did not complete the study in its entirety cited a lack of time and podcast length to be the top two barriers to completion. Conclusion This is one of the first studies to examine extracurricular podcast-usage data and preferences in a Canadian undergraduate medical student population. This information may help educators and FOAM producers to optimize educational tools for medical education. PMID- 29464138 TI - The Use of Twitter by the Trauma and Orthopaedic Surgery Journals: Twitter Activity, Impact Factor, and Alternative Metrics. AB - Aim Social media (SoMe) platforms have become leading methods of communication and dissemination of scientific information in the medical community. They allow for immediate discussion and widespread engagement around important topics. It has been hypothesized that the activity on Twitter positively correlates with highly cited articles. The purpose of this study was to analyze the prevalence and activity of Trauma and Orthopaedic Surgery journals on Twitter, with the hypothesis that the impact factor is positively associated with the Twitter usage. Methods The top 50 Trauma and Orthopaedic Surgery journals, ranked by 2016 Impact Factor were analyzed. The Twitter profiles of each journal or affiliated society were identified. Other SoMe platforms used were also recorded. The Twitonomy software (Digonomy Pty Ltd, New South Wales, Australia) was used to analyze the Twitter profiles over a one-year period. The Twitter Klout scores were recorded for each journal to approximate the SoMe influence. The Altmetric scores (the total number of mentions via alternative metrics) were also recorded. The statistical analysis was carried out to identify correlations between journal Impact Factors, SoMe activity, Twitter Klout scores and Altmetric scores. Results Twenty-two journals (44%) were dedicated to the Twitter profiles. Fourteen journals (28%) were associated with societies that had profiles and 14 journals (28%) had no Twitter presence. The mean Impact Factor overall was 2.16 +/- 0.14 (range, 1.07-5.16). The journals with dedicated Twitter profiles had higher Impact Factors than those without (mean 2.41 vs. 1.61; P=0.005). A greater number of Twitter followers were associated with higher Impact Factors (R2 0.317, P=0.03). The journals with higher Twitter Klout scores had higher Impact Factors (R2 0.357, P=0.016). The Altmetric score was positively associated with an Impact Factor (R2 0.310, P=0.015). The journals with higher numbers of retweets (virtual citations in the Twittersphere) had higher Altmetric scores (R2 0.463, P=0.015). Conclusion The Trauma and Orthopaedic Surgery journals with dedicated Twitter profiles have higher Impact Factors than those without. The Altmetrics is likely to play a significant role in the literature evaluation going forward along with the traditional metrics. The engagement with the Twitter by Trauma and Orthopaedic surgeons should be encouraged. PMID- 29464139 TI - Role of Three-Dimensional Rotational Angiography in the Treatment of Spinal Dural Arteriovenous Fistulas. AB - Spinal dural arteriovenous fistulas (AVFs), being the most commonly encountered spinal vascular malformations, result in considerable morbidity with progressive spinal cord symptoms. A selective spinal digital subtraction angiography (DSA) is needed to confirm the diagnosis, to better evaluate the fine vascular structures and to plan therapy. With the introduction of three-dimensional rotational angiography (3D-RA), the information available for the treating physician has vastly increased. In the following article, we present a case series of four patients, in which the advantages of 3D-RA over the conventional biplane projections could be observed clearly. PMID- 29464140 TI - A Case Report of Recombinant Tissue Plasminogen Activator Use in a SPAN-100 Positive Geriatric Patient with Thrombocytopenia. AB - Thrombocytopenia (platelet count: < 100,000/mm3) is considered a contraindication in the use of intravenous thrombolysis for acute ischemic stroke. Little literature exists regarding tissue plasminogen activator (tPA) usage in thrombocytopenic patients, especially in older patients. Age and stroke severity are major prognostic indicators of the risk of hemorrhagic transformation. The Stroke Prognostication using Age and NIH Stroke Scale (SPAN) index estimates a patient's risk of intracerebral hemorrhage (ICH) and clinical response to thrombolysis by combining age in years with the National Institutes of Health Stroke Scale (NIHSS) scores. If the total numeric sum is 100 or more, these individuals are considered SPAN-100-positive, while those with a sum less than 100 are considered SPAN-100-negative patients. SPAN-100-positive patients are found to have a greater risk of ICH and poorer long-term outcomes than SPAN-100 negative patients both with and without thrombolysis treatment. SPAN-100-positive patients are found to have a greater risk of ICH and poorer long-term outcomes than SPAN-100-negative patients both with and without thrombolysis treatment. Nonetheless, SPAN-100-positive patients treated with tPA have a reduced relative likelihood of severe disability or death than SPAN-100-positive patients not treated with tPA. We report a case of a SPAN-100-positive, 90-year-old community dwelling patient who presented with an acute ischemic stroke, an NIHSS score of 14 with near complete left-sided plegia, and a platelet count of 85,000/mm3. Our patient was at increased risk of ICH and poor outcome regardless of tPA administration. However, due to the patient's high functional capacity prior to hospitalization and probable severe morbidity with poor recovery potential at his age, he was treated with tPA and showed a rapid improvement in neurological symptoms with no thrombolytic-associated morbidity. Thrombolytic therapy requires a case-by-case approach. Taking into account the patient's baseline and recovery potential is critical. Even absolute and relative contraindications, as they stand now, may need reconsideration, particularly those with little empiric evidence. More research is indicated to establish if thrombocytopenia should be reclassified as a relative rather than absolute contraindication to tPA. PMID- 29464141 TI - Survival and Failure Outcomes Predicted by Brain Metastasis Volumetric Kinetics in Melanoma Patients Following Upfront Treatment with Stereotactic Radiosurgery Alone. AB - Introduction The roles of early whole brain radiotherapy (WBRT) and upfront stereotactic radiosurgery (SRS) alone in the treatment of melanoma patients with brain metastasis remain uncertain. We investigated the volumetric kinetics of brain metastasis development and associations with clinical outcomes for melanoma patients who received upfront SRS alone. Methods Volumetric brain metastasis velocity (vBMV) was defined as the volume of new intracranial disease at the time of distant brain failure (DBF) for the first DBF (DBF1) and second DBF (DBF2) averaged over the time since initial or most recent SRS. Non-volumetric brain metastasis velocity (BMV) was calculated for comparison. Results Median overall survival (OS) for all patients was 7.7 months. Increasing vBMVDBF1 was associated with worsened OS (hazard ratio (HR): 1.10, confidence interval (CI): 1.02 - 1.18, p = .01). Non-volumetric BMVDBF1 was not predictive of OS after DBF1 (HR: 1.00, CI: 0.97 - 1.02, p = .77). Cumulative incidence of DBF2 at three months after DBF1 was 50.0% for vBMVDBF1 > 4 cc/yr versus (vs) 15.1% for vBMVDBF1 <= 4 cc/yr, (Gray's p-value = .02). Cumulative incidence of salvage WBRT at three months after DBF1 was 50.0% for vBMVDBF1 > 4 cc/yr vs 2.3% for vBMVDBF1 <= 4 cc/yr (Gray's p-value < .001). Conclusion In melanoma patients with brain metastasis, volumetric BMV was predictive of survival, shorter time to second DBF, and the need for salvage WBRT. Non-volumetric BMV, however, did not predict for these outcomes, suggesting that vBMV is a stronger predictor in melanoma. PMID- 29464142 TI - Decreased Renal Function Is Associated with Elevated CHA2DS2VASC and R2CHADS2 Scores in Non-Valvular Atrial Fibrillation Patients Presenting with Stroke. AB - Introduction Atrial fibrillation (AF), the most common cardiac arrhythmia, affects approximately 2.3 million patients in the United States, costing around $26 billion. Atrial fibrillation is associated with a two- to seven-fold increased risk of stroke, one of the most serious complications. Chronic kidney disease affects approximately 13% of the US population and has been associated with higher rates of AF than the general population. In patients with chronic kidney disease (CKD), the risk of stroke increases as the glomerular filtration rate (GFR) decreases, especially in CKD stages three and four. Several risks stratification scores such as CHADS2 (congestive heart failure, hypertension, age, diabetes mellitus, stroke), CHA2DS2VASc (congestive heart failure, hypertension, age, diabetes mellitus, stroke, vascular disease, age, sex), and R2CHADS2 (renal failure, congestive heart failure, age, diabetes, stroke) scores are used for stroke risk assessment in patients with non-valvular atrial fibrillation (NVAF). This study investigates the association between renal functions and risk stratification scoring systems in patients with non-valvular AF presenting with stroke. Methods Using the convenience sampling method, 171 subjects were selected from the eligible population (n = 386). A Pearson product moment correlation coefficient was calculated to determine the association between the GFR and each of the CHA2DS2VASc and R2CHADS2 scores. In addition, a Pearson product-moment correlation coefficient was calculated to determine the association between the CHA2DS2VASc and R2CHADS2 scores. Results The selected population represented 44.3% of the eligible subjects. Of these, 88% were Caucasian, 60% were female, and the mean age was 78 years. The mean CHA2DS2VASc score was six (range 2-9). The mean eGFR was 69.77 (range 6-108). Both the mode and the median CHA2DS2VASc score was four (range 2-8). A weak, but significant, negative correlation was found between renal function (eGFR) and the CHA2DS2VASc score (r = -0.263; p = 0.0005). There was a stronger negative correlation between the eGFR and R2CHADS2score (r = -0.70; p < 0.00001). The CHA2DS2VASc and R2CHADS2scoring schemes were significantly and positively correlated (r = 0.627; p < 0.00001). Discussion In NVAF patients presenting with stroke, renal failure is associated with higher CHA2DS2VASc and R2CHADS2 scores. One must consider renal failure (end-stage or non-end stage renal failure) as an additional potential risk factor for stroke when recommending anticoagulation in non valvular atrial fibrillation.

AB - Erythroderma is characterized by erythema involving greater than 90% of the body surface area and may be caused by several etiologies, including erythrodermic psoriasis. Psoriasis is an autoimmune skin and systemic condition characterized by erythematous and scaly plaques. Monoclonal B-cell lymphocytosis is an asymptomatic hematological disorder diagnosed by elevated, small, clonal B-cell counts in the peripheral blood. The characteristics of a 71-year-old man with new onset of erythrodermic psoriasis and concurrent monoclonal B-cell lymphocytosis are presented. The simultaneous development of these two conditions raises the possibility that they may share a related pathogenesis. PMID- 29464144 TI - Restrictive Strabismus Following Frontotemporal-orbitozygomatic Craniotomy. AB - The frontotempotal-orbitozygomatic craniotomy (FTOZ) is a standard approach for large sphenoid wing meningiomas (SWMs). Nevertheless, resection of these tumors is not without ophthalmologic risks. This series presents two patients with acute postoperative restrictive strabismus following tumor resection and orbital wall reconstruction. Forced duction testing and postoperative imaging revealed impingement of the lateral rectus muscle caused by an alloplastic implant and/or residual bone, prompting immediate orbitotomy and restoration of normal extraocular muscle function. This report highlights the intricacies of orbital reconstruction, as well as the need for intraoperative forced duction testing.

AB - Objective: Over the past few years, virtual surgical planning (VSP) has evolved into a useful tool for the craniofacial surgeon. Virtual planning and computer aided design and manufacturing (CAD/CAM) may assist in orthognathic, cranio orbital, traumatic, and microsurgery of the craniofacial skeleton. Despite its increasing popularity, little emphasis has been placed on the learning curve. Methods: A retrospective analysis of consecutive virtual surgeries was done from July 2012 to October 2016 at the University of Montreal Teaching Hospitals. Orthognathic surgeries and free vascularized bone flap surgeries were included in the analysis. Results: Fifty-four virtual surgeries were done in the time period analyzed. Forty-six orthognathic surgeries and 8 free bone transfers were done. An analysis of errors was done. Eighty-five percentage of the orthognathic virtual plans were adhered to completely, 4% of the plans were abandoned, and 11% were partially adhered to. Seventy-five percentage of the virtual surgeries for free tissue transfers were adhered to, whereas 25% were partially adhered to. The reasons for abandoning the plans were (1) poor communication between surgeon and engineer, (2) poor appreciation for condyle placement on preoperative scans, (3) soft-tissue impedance to bony movement, (4) rapid tumor progression, (5) poor preoperative assessment of anatomy. Conclusion: Virtual surgical planning is a useful tool for craniofacial surgery but has inherent issues that the surgeon must be aware of. With time and experience, these surgical plans can be used as powerful adjuvants to good clinical judgement. PMID- 29464147 TI - Superficial Inferior Epigastric Artery Flap Salvage Technique Using Deep Inferior Epigastric Artery Graft. AB - Superficial inferior epigastric artery (SIEA) flap salvage remains challenging, particularly in cases of arterial insufficiency due to vessel spasm, pedicle kinking, or thrombosis. The already small, short SIEA pedicle, in addition to its inherent tendency toward spasm, renders the SIEA flap more difficult to manage when anastomotic revision is required. Furthermore, arterial thrombosis will cause dilation of the internal mammary artery, exacerbating vessel mismatch. In our previously published experience with 145 SIEA flaps, no flap with postoperative arterial thrombosis was salvageable. Following this experience, a new salvage technique using deep inferior epigastric artery grafts has been utilized and is described here. PMID- 29464148 TI - Immediate Breast Reconstruction among Patients with Medicare and Private Insurance: A Matched Cohort Analysis. AB - Background: By eliminating economic hurdles, the Women's Health and Cancer Rights Act of 1998 represented a paradigm shift in the availability of breast reconstruction. Yet, studies report disparities among Medicare-insured women. These studies do not account for the inherent differences in age and comorbidities between a younger privately insured and an older Medicare population. We examined immediate breast reconstruction (IBR) utilization between a matched pre- and post-Medicare population. Methods: Using the Nationwide Inpatient Sample database (1992-2013), breast cancer patients undergoing IBR were identified. To minimize confounding medical variables, 64-year-old privately insured women were compared with 66-year-old Medicare-insured women. Demographic data, IBR rates, and complication rates were compared. Trend over time was plotted for both cohorts. Result: A total of 21,402 64-year-old women and 25,568 66-year-old women were included. Both groups were well matched in terms of demographic type of reconstruction and complication rates. 72.3% of 64-year-old and 71.2 of % 66-year-old women opted for mastectomy. Of these, 25.5% (n = 3,941) of 64-year-old privately insured and 17.7% (n = 3,213) of 66-year-old Medicare insured women underwent IBR (P < 0.01). During the study period, IBR rates increased significantly in both cohorts in a similar cohort. Conclusion: This study demonstrates significant increasing IBR rates in both cohorts. Moreover, after an initial slower upward trend, after a decade, IBR in 66-year-old Medicare insured women approached similar rates of breast reconstruction among those with private insurance. Trends in unilateral versus bilateral mastectomy are also seen. PMID- 29464149 TI - Microsurgical Engineering: Bilateral Deep Inferior Epigastric Artery Perforator Flap with Flow-Through Intraflap Anastomosis. AB - Squamous cell carcinoma (SCC) of the head and neck affects a significant number of people around the world every year. Treatment generally entails surgical resection, radiotherapy, chemotherapy, or some combination of the three. Following resection, microsurgical reconstruction can provide definitive coverage, replace many tissue types simultaneously, and bring healthy tissue to irradiated wound beds. Microsurgical engineering, the manipulation and reorganization of native vascular tissue, can further augment the adaptability of free tissue transfer to complex, compromised wound beds. We present one such case. The patient described in the following report was treated for a recurrent SCC of the left face, which required extensive resection resulting in a complex, composite tissue defect with compromised vascular supply. Using the principals of microsurgical engineering, definitive coverage of the defect, with accept- able aesthetic result, was achieved via bipedicle, DIEP flap with flow-through intraflap anastomosis. PMID- 29464150 TI - Incisional Negative Pressure Wound Therapy for Prevention of Wound Healing Complications Following Reduction Mammaplasty. AB - Background: It has been proposed that negative pressure wound therapy (NPWT) applied prophylactically to a closed incision may decrease the incidence of wound complications. Patients undergoing reduction mammaplasty are at risk of wound complications such as delayed healing, infection, and dehiscence, and the bilateral nature of the surgery allows for a within-patient randomized study to evaluate incisional NPWT's effect in reducing healing complications. Methods: In this multicenter trial, 200 patients undergoing bilateral reduction mammaplasty were treated with PICO Single-Use NPWT System or standard wound-care dressings randomized to right or left breast for up to 14 days to enable within-patient comparison. Follow-up assessments were conducted to evaluate the difference in incision healing complications up to 21 days postsurgery. Healing complications (for the primary endpoint) were defined as delayed healing (incision not 100% closed by 7 days) and occurrence of dehiscence or infection within 21 days. Individual healing complications were assessed separately as secondary endpoints. Results: Significantly fewer healing complications (primary endpoint) were noted in NPWT-treated breasts [113 (56.8%)] versus standard care [123 (61.8%)]. The difference of 10 (5.0%) patients with fewer healing complications using NPWT was statistically significant (P = 0.004). NPWT also resulted in a significantly lower incidence of dehiscence (secondary endpoint) compared with standard care [32 patients (16.2%) versus 52 patients (26.4%)] by day 21, a relative reduction of 38% (P < 0.001). Conclusions: This is the first major prospective, within patient, randomized, controlled, multicenter study to provide evidence for an incisional NPWT strategy to reduce healing complications. PMID- 29464151 TI - The Pedicled LICAP Flap Combined with a Free Abdominal Flap In Autologous Breast Reconstructions. AB - Background: Previous surgery or slim body configuration can limit the size of the available abdominal flap in autologous breast reconstruction. However, redundant skin and subcutaneous tissue lateral to the mastectomy site can be utilized as the pedicled lateral intercostal artery perforator (LICAP) flap. This study evaluates the combination of a free abdominal flap and a pedicled LICAP flap to achieve increased breast size and improved cosmetic outcome. Methods: Patients undergoing secondary autologous breast reconstruction were included in a prospective study. The combination with a LICAP flap was used for women with insufficient abdominal flap tissue in relation to the desired breast size. The authors also assessed their modification of the original lateral thoracodorsal flap design to improve the aesthetic outcome. Results: In 109 patients, 121 free abdominal flaps were performed. The combination with a pedicled LICAP flap was used in 82 free abdominal flap reconstructions (68%). The LICAP flap provided additional volume and resulted in better projection and ptosis of the neo-mamma. The overall complication rate for the LICAP flaps was 26 %; all minor complications. Despite combining flaps, the majority of patients needed additional surgery to improve breast symmetry. Breast reduction of the native breast was the most common symmetrizing procedure. Conclusion: In selected patients with insufficient abdominal flap tissue, a combination of a free abdominal flap and a pedicled LICAP flap is a valuable option to increase breast size and cosmetic outcome. Additional symmetrizing surgery might still be necessary. PMID- 29464152 TI - Light-emitting Diode Transilluminator for the Identification of Recipient Veins in Finger Reconstruction. AB - Supplemental Digital Content is available in the text. PMID- 29464153 TI - SSET Project: Cost-effectiveness Analysis of Surgical Specialty Emergency Trays in the Emergency Department. AB - Background: We hypothesize that reusable, on-site specialty instrument trays available to plastic surgery residents in the emergency department (ED) for bedside procedures are more cost-effective than disposable on-site and remote re usable operating room (OR) instruments at our institution. Methods: We completed a cost-effectiveness analysis comparing the use of disposable on-site kits and remote OR trays to a hypothetical, custom, reusable tray for ED procedures completed by PRS residents. Material costs of existing OR trays were used to estimate the purchasing and use-cost of a custom on-site tray for the same procedures. Cost of per procedure 'consult time' was estimated using procedure and resident salary. Results: Sixteen bedside procedures were completed over a 4.5 month period. A mean of 2.14 disposable kits were used per-procedure. Mean consultation time was 1.66 hours. Procedures that used OR trays took 3 times as long as procedures that used on-site kits (4 vs. 1.1 hours). Necessary, additional instruments were unavailable for 75% of procedures. Mean cost of using disposable kits and OR trays was $115.03/procedure versus an estimated $26.67/procedure cost of using a custom tray, yielding $88.36/procedure cost savings. Purchase of a single custom tray ($1,421.55) would be redeemed after 2.3 weeks at 1 procedure/day. Purchasing 4 trays has projected annual cost-savings of $26,565.20. Conclusion: The purchase of specialized procedure trays will yield valuable time and cost-savings while providing quality patient care. Improving time efficiency will help achieve the Accreditation Council of Graduate Medical Education (ACGME) goals of maintaining resident well-being and developing quality improvement competency. PMID- 29464154 TI - V-shaped Internal Nasal Vestibular Flap for Reconstruction of Iatrogenic Columellar Defect. AB - Columella is an important structure in the center of the face, and its structural integrity has an important functional, social, and psychological role. Columella reconstruction can be very challenging for surgeons and the ideal technique remains elusive. This article describes a reconstruction technique in a young woman with columella necrosis due to nasal continuous positive airway pressure treatment. The method of reconstruction described here, with a V-shaped internal nasal vestibular flap and a cartilage grafts from lateral crura, is simple and easily reproducible, providing an optimal aesthetic result and in addition the donor site does not create a secondary deformity by disrupting normal anatomy. PMID- 29464155 TI - Single-Stage Breast Reconstruction Using an All-In-One Adjustable Expander/Implant. AB - Background: When tissue expansion is necessary in breast reconstruction, a single stage approach is possible using adjustable expander/implants, with or without the use of acellular dermal matrix. We aimed to present the senior author's single-stage experience over a period of 12 years using combined expander/implants in breast reconstruction. Methods: This is a Single institution, retrospective review of breast reconstruction with combined expander/implants from 2002 to 2014. Logistic regression was performed to evaluate the impact of multiple variables on long-term outcomes. Results: A total of 162 implants in 105 patients were included in this study. Mean follow-up time was 81.7 months (SD, +/- 39.2; range, 15-151). Complication rates were as follows: 0.62% extrusion, 1.2% mastectomy flap necrosis, 1.2% hematoma, 1.9% dehiscence, 2.5% seroma, 4.9% infection, and 15.4% deflation. The following associations were identified by logistic regression: adjuvant radiotherapy and capsular contracture (P = 0.034), tumor size and deflation (P = 0014), and smoking history and infection (P = 0.013). Conclusions: Overall, 81% of breasts were successfully reconstructed in a single stage. Single-stage reconstruction using all-in-one expander/implants reduces costs by eliminating the need for a second procedure under general anesthesia and can achieve results comparable with other alloplastic reconstructions reported in the literature. PMID- 29464156 TI - Structural and Mechanical Comparison of Human Ear, Alar, and Septal Cartilage. AB - Background: In the human ear and nose, cartilage plays a key role in establishing its form and function. Interestingly, there is a noticeable paucity on biochemical, structural, and mechanical studies focused on facial cartilage. Such studies are needed to provide elementary knowledge that is fundamental to tissue engineering of cartilage. Therefore, in this study, a comparison is made of the biochemical, structural, and mechanical differences between ear, ala nasi, and septum on the extracellular matrix (ECM) level. Methods: Cartilage samples were harvested from 10 cadaveric donors. Each sample was indented 10 times with a nanoindenter to determine the effective Young's modulus. Structural information of the cartilage was obtained by multiple-photon laser scanning microscopy capable of revealing matrix components at subcellular resolution. Biochemistry was performed to measure glycosaminoglycan (GAG), DNA, elastin, and collagen content. Results: Significant differences were seen in stiffness between ear and septal cartilage (P = 0.011) and between ala nasi and septal cartilage (P = 0.005). Elastin content was significantly higher in ear cartilage. Per cartilage subtype, effective Young's modulus was not significantly correlated with cell density, GAG, or collagen content. However, in septal cartilage, low elastin content was associated with higher stiffness. Laser microscopy showed a distinct difference between ear cartilage and cartilage of nasal origin. Conclusion: Proposed methods to investigate cartilage on the ECM level provided good results. Significant differences were seen not only between ear and nasal cartilage but also between the ala nasi and septal cartilage. Albeit its structural similarity to septal cartilage, the ala nasi has a matrix stiffness comparable to ear cartilage. PMID- 29464157 TI - Clinical Significance of Venous Anomalies in Syndromic Craniosynostosis. AB - Background: The pattern of cranial venous drainage in syndromic craniosynostosis is unpredictable and not adequately understood. Collateral channels substitute for stenotic venous sinuses and pose potential risk for surgical intervention. The purpose of this study was to analyze the patterns of venous drainage in patients with syndromic craniosynostosis and their influence on operative planning and morbidity. Methods: A retrospective study of patients with syndromic craniosynostosis from 2000 to 2013 was performed. Demographic data were collected including phenotype and associated pathologies. Pre- and/or postoperative venous imaging was reviewed for venous sinus stenosis, collateral emissaries, and persistent fetal sinuses. Categorization of anomalous venous drainage was performed, and the relationship with surgical morbidity was assessed. Results: Forty-one patients were identified. Anomalies were present in 31 patients (76%) consisting of dural sinus stenosis in 28 (68%), dilated emissaries in 26 (63%), and fetal sinuses in 7 (17%). Pfeiffer syndrome was most commonly associated with anomalous drainage (100%). Venous anomalies were associated with elevated intracranial pressure (ICP), shunted hydrocephalus, Chiari malformations, and sleep apnea. In 5 cases, the surgical plan was adjusted based on anomalous anatomy. No mortalities occurred. Intraoperative complication rate was 7.3%, all with anomalous drainage. Median estimated blood loss was 1,100 cc for patients with anomalies versus 400 cc without anomalies (P = 0.181). Conclusion: Cranial venous anomalies are commonly detected in patients with syndromic craniosynostosis and may affect surgical morbidity and outcome with a higher estimated blood loss, alteration of procedure, and postoperative morbidity. Detailed preoperative imaging of the venous drainage is therefore recommended in cases of syndromic synostosis. PMID- 29464158 TI - Hyperbaric Oxygen for Ischemia due to Injection of Cosmetic Fillers: Case Report and Issues. AB - Natural and synthetic fillers have revolutionized aesthetic facial rejuvenation and soft-tissue augmentation. We present a case highlighting the dangers of filler self-injection. A 37-year-old woman self-injected a dermal filler around both temples. She immediately experienced left--side hearing loss, blanching over the left face, and pain. Prompt treatment with hyaluronidase, topical nitro paste, and warm compresses ensued. An emergency computed tomography angiogram showed occlusion of a superficial temporal artery branch. We treated her with enoxaparin, aspirin, dexamethasone, piperacillin-tazobactam, and intradermal lidocaine. After 6 hyperbaric oxygen therapy (HBO2) treatments in 3 days, the patient showed improvement in appearance with markedly decreased ischemic discoloration and her hearing returned to baseline. Algorithms for treating such injuries generally neglect HBO2. HBO2 is thought to be efficacious in these situations by a variety of mechanisms: oxygenation of ischemic tissues, reduction of edema, amelioration of ischemic/reperfusion injury, promotion of angiogenesis and collagen maturation. Her resolved hearing highlights the utility of HBO2 in sudden hearing loss as well. Injectors should have guidelines for using product, not only on patients but staff as well. Filler courses should include handling complications and include HBO2 in their guidelines. Clinicians should remind patients to seek treatment from qualified clinicians. The goal of a bargain price using self-injection may quickly become expensive and disfiguring. PMID- 29464159 TI - The Use of Vibrational Energy to Isolate Adipose-Derived Stem Cells. AB - Background: Adipose-derived stem cell (ADSC)-based treatments have the potential to treat numerous soft-tissue pathologies. It would be beneficial to develop an efficient and reliable intraoperative, nonenzymatic method of isolating ADSCs for clinical use. This study aims to determine the (1) viability and proliferative capacity of ADSCs after exposure to vibrational energies and (2) efficacy of vibrational energy as a method of ADSC isolation from surgically harvested infrapatellar fat pad (IFP). Methods: Cultured ADSCs were exposed to 15 minutes of vibration (60 Hz) with displacements ranging from 0 to 2.5 mm to assess cell viability and proliferation. Then, arthroscopically harvested adipose tissue (IFP; n = 5 patients) was filtered and centrifuged to separate the stromal vascular fraction, which was exposed to 15 minutes of vibration (60 Hz; 1.3 mm or 2.5 mm displacement). A viability analysis was then performed along with proliferation and apoptosis assays. Results: Vibration treatment at all displacements had no effect on the viability or proliferation of the cultured ADSCs compared with controls. There was an increased apoptosis rate between the 2.5 mm displacement group (7.53%) and controls (5.17%; P < 0.05) at day 1, but no difference at days 2, 3, and 14. ADSCs were not isolated from the IFP tissue after vibration treatment. Conclusions: ADSCs maintained viability and proliferative capacity after 15 minutes of vibration at 60 Hz and 2.5 mm displacement. ADSCs were not isolated harvested IFP tissue after the application of vibrational energy. PMID- 29464160 TI - Earfold Implantable Clip System for Correction of Prominent Ears: Analysis of Safety in 403 Patients. AB - Background: The Earfold system, a new treatment for the correction of prominent ears, consists of 3 components: the Earfold implant, the Earfold introducer, and the Prefold positioner. Methods: This is an interim report based on an ongoing analysis of safety in a series of patients treated for prominent ears with the Earfold implant between February 2013 and September 2014. Safety was assessed based on adverse event reports and the need for implant revision; follow-up is ongoing. Results: Seven surgeons used 1,200 Earfold implants to treat 403 patients (ages, 7-70 years; 63% male); the time since the initial implant procedure now ranges from 30 to 48 months. To date, 145 patients (36%) have returned for a follow-up visit (mean, 7.7 months [range, 1-34 months]). Adverse events requiring intervention have affected 39 of 403 (9.7%) patients; these include implant revisions (n = 17 [4.2%], most often due to implant visibility), skin erosion over the implant (n = 15 [3.7%]), and infection (n = 7 [1.7%]). Bleeding, recurrence of prominence, hematoma, deformity, or adverse scarring did not occur. Conclusions: This interim analysis has shown that Earfold prominent ear correction system is associated with relatively few adverse events that require intervention; a small number of patients experienced infection, implant extrusion, or implant visibility that required revision. Most adverse events were related to either patient selection or technical errors at implantation. It is expected that with continued use of Earfold by surgeons experienced in otoplasty, the adverse event incidence will decrease. PMID- 29464161 TI - Complications following Nipple-Sparing Mastectomy and Immediate Acellular Dermal Matrix Implant-based Breast Reconstruction-A Systematic Review and Meta-analysis. AB - Background: Acellular dermal matrix was introduced in breast reconstruction in 2001 and is gradually becoming a standard component for immediate breast reconstruction and nipple-sparing mastectomy. The reconstructive technique allows for improved aesthetic outcomes. However, there seems to be uncertainty regarding complication rates. The aim of this review was to systematically evaluate complication rates related to this method. Methods: This systematic review was conducted according to the recommendations outlined in the Cochrane Handbook for reviews and reported in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Relevant databases were searched for in the literature concerning the use of acellular dermal matrix in implant-based nipple sparing mastectomy and immediate breast reconstruction. All studies underwent detailed quality assessment. Summarized outcome rates were computed using meta analysis. Results: Nine of 1,039 studies were eligible for inclusion yielding 778 procedures. The quality was acceptable for all included studies. The meta analysis found the rate of skin necrosis to be 11%, nipple necrosis 5%, infection in 12%, hematoma in 1%, treated seroma in 5%, explantation 4%, and unplanned return to the operating room in 9%. Conclusion: The use of acellular dermal matrix in nipple-sparing mastectomy and implant-based breast reconstruction can be done with acceptable complication rates in selected patients. We recommend future studies to include specific definitions when reporting complication rates. Furthermore, future studies should elaborate on demographic characteristics of the included study samples and include predictor analysis to enhance knowledge of high risk patients. PMID- 29464162 TI - Hinge Flap with Triangular Extension for Reconstruction of Pharyngocutaneous and Laryngocutaneous Fistulas. AB - Hinge flaps are commonly used for closure of a pharyngocutaneous fistula (PCF) or laryngocutaneous fistula. These flaps are employed to augment the wall of the pharynx or larynx, but the junction between the reconstructed and native lumens can eventually become narrow and irregular after reconstruction with standard hinge flaps. We devised a method of adding a triangular extension to the end of either or both flaps and used it to treat 3 patients. In 1 patient who developed a PCF (4 * 10 cm) after laryngectomy followed by radiotherapy, the fistula was closed with 2 hinge flaps. One flap had a caudal triangular extension. The residual skin defect was covered by a pedicled latissimus dorsi musculocutaneous flap. Another patient who developed a PCF (2.5 * 3 cm) after laryngectomy underwent 2-stage reconstruction using a buccal mucosal graft with a triangular extension, followed by 2 hinge flaps. A patient who developed an laryngocutaneous fistula (1 * 2 cm) after radiotherapy and subsequent partial laryngectomy underwent reconstruction using 2 hinge flaps, each of which had a triangular extension. The skin defect was covered by another flap. Postoperative CT or video fluoroscopic examination of swallowing showed a smooth lumen with no strictures in all 3 patients. The triangular extension of the hinge flap supplements the pharyngeal/laryngeal wall at the junction between the reconstructed and intact regions, thus avoiding postoperative stricture. Especially with PCF reconstruction, restoration of a smooth luminal surface minimizes dysphagia. PMID- 29464163 TI - Innovative Use of Thighplasty to Improve Prosthesis Fit and Function in a Transfemoral Amputee. AB - Background: Excess residual limb fat is a common problem that can impair prosthesis control and negatively impact gait. In the general population, thighplasty and liposuction are commonly performed for cosmetic reasons but not specifically to improve function in amputees. The objective of this study was to determine if these procedures could enhance prosthesis fit and function in an overweight above-knee amputee. Methods: We evaluated the use of these techniques on a 50-year-old transfemoral amputee who was overweight. The patient underwent presurgical imaging and tests to measure her residual limb tissue distribution, socket-limb interface stiffness, residual femur orientation, lower-extremity function, and prosthesis satisfaction. A medial thighplasty procedure with circumferential liposuction was performed, during which 2,812 g (6.2 lbs.) of subcutaneous fat and skin was removed from her residual limb. Imaging was repeated 5 months postsurgery; functional assessments were repeated 9 months postsurgery. Results: The patient demonstrated notable improvements in socket fit and in performing most functional and walking tests. Her comfortable walking speed increased 13.3%, and her scores for the Sit-to-Stand and Four Square Step tests improved over 20%. Femur alignment in her socket changed from 8.13 to 4.14 degrees, and analysis showed a marked increase in the socket-limb interface stiffness. Conclusions: This study demonstrates the potential of using a routine plastic surgery procedure to modify the intrinsic properties of the limb and to improve functional outcomes in overweight or obese transfemoral amputees. This technique is a potentially attractive option compared with multiple reiterations of sockets, which can be time-consuming and costly. PMID- 29464164 TI - An Enhanced Recovery after Surgery Pathway for Microvascular Breast Reconstruction Is Safe and Effective. AB - Background: The aim of this study was to develop, implement, and evaluate a standardized perioperative enhanced recovery after surgery (ERAS) clinical care pathway in microsurgical abdominal-based breast reconstruction. Methods: Development of a clinical care pathway was informed by the latest ERAS guideline for breast reconstruction. Key features included shortened preoperative fasting, judicious fluids, multimodal analgesics, early oral nutrition, early Foley catheter removal, and early ambulation. There were 3 groups of women in this cohort study: (1) traditional historical control; (2) transition group with partial implementation; and (3) ERAS. Narcotic use, patient-reported pain scores, antiemetic use, time to regular diet, time to first walk, hospital length of stay, and 30-day postoperative complications were compared between the groups. Results: After implementation of the pathway, the use of parenteral narcotics was reduced by 88% (traditional, 112 mg; transition, 58 mg; ERAS, 13 mg; P < 0.0001), with no consequent increase in patient-reported pain. Patients in the ERAS cohort used less antiemetics (7.0, 5.3, 2.2 doses, P < 0.0001), returned to normal diet 19 hours earlier (46, 39, 27 hours, P < 0.0001), and walked 25 hours sooner (75, 70, 50 hours, P < 0.0001). Overall, hospital length of stay was reduced by 2 days in the ERAS cohort (6.6, 5.6, 4.8 days, P < 0.0001), without an increase in rates of major complications (9.5%, 10.1%, 8.3%, P = 0.9). Conclusions: A clinical care pathway in microsurgical breast reconstruction using the ERAS Society guideline promotes successful early recovery.

AB - Background: The lateral arm flap is used for composite defects in need of vascularized soft tissue, skin, and bone. From its original description, the distal humeral metaphysis can be included with the flap, supplied by the periosteal extensions of the posterior branch of the radial collateral artery. We sought to reexplore the anatomy of the lateral arm to determine its utility as a donor site for vascularized bone. Methods: Twelve fresh, silicone-injected cadaver dissections were performed. Arteriovenous anatomy, pedicle length and diameter, and anatomic variability as well as photo documentation was recorded. Results: The distal extent of the deltoid, lateral intermuscular septum and lateral humeral epicondyle were identified before the dissection. A septocutaneous perforator was consistently located 10 cm proximal to the lateral humeral epicondyle, which could be used for a skin paddle to monitor. Harvest of a 1.5 cm * 2 cm corticocancellous bone graft was performed. Average pedicle length was 9.1 +/- 1.1 cm, and average pedicle diameter was 1.74 +/- 0.52 mm. The inferior lateral cutaneous nerve of the arm and the posterior cutaneous nerve of the forearm were consistently identified and preserved. Conclusion: The predictable anatomy of the lateral distal humerus make it an ideal donor site for small segments of vascularized bone.

AB - Replantation is the reattachment of a severed body part, with attempts to restore neurovascular and musculoskeletal integrity, function, and aesthetics. On September 7, 1964, the first extremity replantation-a completely amputated hand by vascular anastomosis technique was successfully performed.1 Soon after, the first replantation of a complete thumb amputation using microvascular anastomosis in a human was successfully conducted by Komatsu et al.2 in 1968. The overall success rate of limb replantation surgery is around 83.2%.3 The mechanism of injury plays a role in the outcome; guillotine amputations-for example-carry a better prognosis than crush amputations.4 We present a case report of a 36-year old male patient who presented with a total avulsion of the right hand with multiple fracture levels at the level of trans-carpal, distal radius extra articulation fracture, and total avulsion of the hand. The patient was managed by a multidisciplinary team who were able to reattach his hand successfully with good functional outcome. PMID- 29464167 TI - Use of Viable Cryopreserved Placental Membrane as an Adjunct to Facial Keloid Resection. AB - Keloids are the physical manifestation of an exaggerated inflammatory response resulting in excess collagen deposition. The resulting fibroproliferative mass can be distressing for patients due to appearance, pruritus, and/or pain. Despite extensive research into the pathophysiology of keloid formation and the development of numerous treatments, keloids remain a challenge to treat. Even when the initial treatment is successful, a risk of recurrence remains. Basic science research into viable cryopreserved placental membranes and viable cryopreserved umbilical tissue has demonstrated their anti-inflammatory and anti fibrotic effects, which may decrease keloid recurrence after excision. In this article, we present the first-reported case of viable cryopreserved placental membrane, with living mesenchymal stem cells, to treat a painful preauricular keloid in conjunction with surgical resection. PMID- 29464168 TI - Treatment Strategies for Hypopigmentation in the Context of Burn Hypertrophic Scars. AB - Dyspigmentation in burn scars can contribute to the development of psychosocial complications after injury and can be detrimental to social reintegration and quality of life for burn survivors. Although treatments for skin lightening to treat hyperpigmentation have been well reviewed in the literature, skin-darkening strategies to treat hypopigmentation have not. The following potential treatment options in the context of burn hypertrophic scar will be discussed: use of the melanocyte-keratinocyte transplantation procedure, use of ectopic synthetic analogues of alpha-melanocyte stimulating hormone to initiate melanogenesis, and use of FK506 to induce melanogenesis. A proposed future direction of research in laser-assisted drug delivery of inducers of local melanin production, with the hope of developing a targeted, effective approach to dyspigmentation in hypertrophic scar is also discussed. PMID- 29464169 TI - Enhanced Preoperative Deep Inferior Epigastric Artery Perforator Flap Planning with a 3D-Printed Perforasome Template: Technique and Case Report. AB - Optimizing preoperative planning is widely sought in deep inferior epigastric artery perforator (DIEP) flap surgery. One reason for this is that rates of fat necrosis remain relatively high (up to 35%), and that adjusting flap design by an improved understanding of individual perforasomes and perfusion characteristics may be useful in reducing the risk of fat necrosis. Imaging techniques have substantially improved over the past decade, and with recent advances in 3D printing, an improved demonstration of imaged anatomy has become available. We describe a 3D-printed template that can be used preoperatively to mark out a patient's individualized perforasome for flap planning in DIEP flap surgery. We describe this "perforasome template" technique in a case of a 46-year-old woman undergoing immediate unilateral breast reconstruction with a DIEP flap. Routine preoperative computed tomographic angiography was performed, with open-source software (3D Slicer, Autodesk MeshMixer and Cura) and a desktop 3D printer (Ultimaker 3E) used to create a template used to mark intra-flap, subcutaneous branches of deep inferior epigastric artery (DIEA) perforators on the abdomen. An individualized 3D printed template was used to estimate the size and boundaries of a perforasome and perfusion map. The information was used to aid flap design. We describe a new technique of 3D printing a patient-specific perforasome template that can be used preoperatively to infer perforasomes and aid flap design. PMID- 29464170 TI - Adjuvant Therapy for Revision Rhinoplasty of Contracted Nose Using Polydeoxyribonucleotide and Invasive Bipolar Radiofrequency. AB - Most cases of severely contracted nose require revision rhinoplasty and septoplasty, wherein preoperative and/or intraoperative expansion of nasal soft tissue is necessary for tension-free revision surgery. The present study aimed to evaluate the efficacy and safety of pre- and postoperative adjuvant therapy using polydeoxyribonucleotide (PDRN) and invasive, pulsed-type, bipolar, alternating current radiofrequency (RF) for revision surgery of a contracted nose. In total, 30 patients were treated with 16 sessions (8 preoperative sessions and 8 postoperative sessions) of intralesional injection of PDRN and invasive RF treatment using microneedle electrodes at 1-week intervals. One week after the final combined pretreatment using PDRN and invasive bipolar RF, the skin of contracted noses was sufficiently softened, and nasal skin mobility was notably improved in all the patients. During revision rhinoplasty and septoplasty, the contracted nasal skin in each patient was adequately released for proper covering of the nasal tip without tension. Postoperatively, 8 sessions of adjuvant therapy elicited marked clinical improvements in persistent nasal tip dimpling and contracture, septal deviation, and warping from the incomplete recovery of nasal contracture after revision surgery. In conclusion, our pre- and postoperative adjuvant therapies using PDRN and invasive bipolar RF remarkably improved the therapeutic outcomes of revision rhinoplasty and septoplasty for contracted skin of the nose without major side effects. PMID- 29464171 TI - Dimensional Error in Rapid Prototyping with Open Source Software and Low-cost 3D printer. AB - Rapid prototyping models (RPMs) had been extensively used in craniofacial and maxillofacial surgery, especially in areas such as orthognathic surgery, posttraumatic or oncological reconstructions, and implantology. Economic limitations are higher in developing countries such as Mexico, where resources dedicated to health care are limited, therefore limiting the use of RPM to few selected centers. This article aims to determine the dimensional error of a low cost fused deposition modeling 3D printer (Tronxy P802MA, Shenzhen, Tronxy Technology Co), with Open source software. An ordinary dry human mandible was scanned with a computed tomography device. The data were processed with open software to build a rapid prototype with a fused deposition machine. Linear measurements were performed to find the mean absolute and relative difference. The mean absolute and relative difference was 0.65 mm and 1.96%, respectively (P = 0.96). Low-cost FDM machines and Open Source Software are excellent options to manufacture RPM, with the benefit of low cost and a similar relative error than other more expensive technologies. PMID- 29464172 TI - Free Flap Survival Despite Internal Jugular Vein Thrombosis in Head and Neck Reconstruction. AB - Microvascular free tissue transfer is one of the most common techniques of reconstruction for complex head and neck surgical defects. Generally, venous thrombosis is more likely to occur than arterial thrombosis in vascular anastomosis. Thus, recipient veins must be chosen carefully. Although the internal jugular vein is preferred as a recipient vein by many microsurgeons, internal jugular vein thrombosis is a potential complication, as shown in our report. Therefore, we consider that the external jugular vein still is an option as a recipient for venous anastomosis and that it is better to perform multiple vein anastomoses with 2 different venous systems, such as the internal and external jugular systems, than anastomoses within the same venous system. PMID- 29464173 TI - Temporomandibular Joint Septic Arthritis. AB - Infection of the temporomandibular joint (TMJ) is a rare pediatric condition resulting from the introduction of pathogens into the joint by hematogenous seeding, local extension, or trauma. Early recognition of the typical signs and symptoms including fever, trismus, preauricular swelling, and TMJ region tenderness are critical in order to initiate further evaluation and prevent feared complications of fibrosis, ankylosis, abnormal facial structure, or persistence of symptoms. Contrast-enhanced computed tomography with ancillary laboratory analysis including erythrocyte sedimentation rate, C-reactive protein, and white blood cell count are beneficial in confirming the suspected diagnosis and monitoring response to therapy. Initial intervention should include empiric parenteral antibiotics, early mandibular mobilization, and joint decompression to provide synovial fluid for analysis including cultures. This report describes a case of TMJ bacterial arthritis in a healthy 6-year-old male who was promptly treated nonsurgically with intravenous antibiotics and localized needle joint decompression with return to normal function after completion of oral antibiotics and physical therapy. PMID- 29464174 TI - Suture Technique to Prevent Air Leakage during Negative-Pressure Wound Therapy in Fournier Gangrene. AB - Background: The use of negative-pressure wound therapy (NPWT) for Fournier gangrene management is well documented; however, it is difficult to fixate GranuFoam dressings and maintain an airtight seal over the perineum area. We developed a simple method to facilitate GranuFoam fixation and improve airtight sealing. Methods: The Fournier's gangrene severity index (FGSI) score less than 9 was collected in from January 2015 to October 2016. All 13 patients underwent fasciotomy, and NPWT was applied directly on fasciotomy wounds after the debridement of infected tissue. Partial wound closure was performed, and a portion of GranuFoam was inserted to facilitate fixation. The seal check was converted to a 0-10 scale score that was recorded every 4 hours during NPWT. Patient profiles including medical history, FGSI, method of wound closure, and length of stay were collected in this study. Results: The median age of the patients was 62 (38-76) years. The mean FGSI score was 4.3 +/- 3.1. The average duration of NPWT was 17.5 +/- 11.5 days, and the average seal check score was 0.8 +/- 0.5. No seal check alarms were noted during the study. Successful wound closure was achieved in all patients without using additional reconstruction methods such as skin grafting or muscle flap coverage. Conclusions: The present results suggest that partial wound-edge closure and in situ GranuFoam fixation improve the NPWT leaks in Fournier gangrene wounds. Furthermore, this method is simple to learn and can be useful in applying NPWT to anatomically difficult areas. PMID- 29464175 TI - Quality Improvement in Facial Transplantation: Standard Approach for Novel Procedures. PMID- 29464176 TI - Latissimus Dorsi and Immediate Fat Transfer (LIFT) for Complete Autologous Breast Reconstruction. AB - Background: Despite the popularity of latissimus dorsi (LD) flap in breast reconstruction, a breast implant is often necessary to achieve sufficient volume. Prior reports describe fat grafting to the LD flap as a secondary procedure to correct contour deformities and improve volume. Our institution has instituted autologous breast reconstruction with an LD flap and immediate fat transfer (LIFT). Methods: A retrospective review of all patients undergoing the LIFT procedure was undertaken. Patient age, total volume of fat transfer, length of follow-up, need for adjuvant therapy, and complications were recorded. The procedure begins with harvest of the LD flap and fat. Prior to disorigination of the latissimus muscle, fat is injected into the flap. Flap harvest is then completed and inset to create a breast mound. Results: Eighteen patients underwent LIFT procedures over 3 years with an average follow-up of 8.7 months (range, 2-24). Four breasts (22.2%) had previously received adjuvant radiation therapy. The mean total fat grafting volume was 515.5 mL (range, 325-730) per breast. The average estimated fat graft take was 66.8% (range, 50-80%). Four patients (22.2%) experienced complications. Conclusion: Autologous augmentation of the LD flap with lipotransfer has been used to avoid placement of an implant. We improve the technique by performing lipotransfer during index reconstruction. Furthermore, we perform lipotransfer prior to disorigination of the LD muscle to minimize trauma to the flap and increase the efficiency of fat grafting. Our experience demonstrates that this technique is a viable autologous alternative to microsurgical breast reconstruction. PMID- 29464177 TI - TB or not TB? Mycobacterium celatum mimicking Mycobacterium tuberculosis: A case of mistaken identity. AB - Mycobacterium celatum is a slow-growing, non-tuberculous mycobacterium (NTM) and a rare cause of infection in humans. Infection occurs primarily by inhalation or direct inoculation from environmental sources, and this pathogen has been reported to cause localized infections in the lungs and lymph nodes of both immunocompetent and immunocompromised patients, and disseminated disease in immunocompromised patients. Here, we present a case of pulmonary infection with M. celatum in an immunocompetent 68-year-old male with clinical features similar to tuberculosis. The patient initially developed palpitations, worsening fatigue, night sweats, dyspnea, productive cough, and weight loss. Computed tomography angiogram of the chest revealed a right upper lobe pulmonary artery embolus and extensive biapical fibronodular cavitary densities. Two separate sputum samples were positive for acid-fast bacilli (AFB) and sputum cultures were positive for M. celatum. The patient responded well to treatment with clarithromycin, ciprofloxacin, and ethambutol. We advise physicians to consider M. celatum infection in the differential diagnosis of patients with symptoms and radiographic and microbiologic evidence suggestive of NTM pulmonary infection. PMID- 29464178 TI - Diagnostic Accuracy of Platelet Count and Platelet Indices in Noninvasive Assessment of Fibrosis in Nonalcoholic Fatty Liver Disease Patients. AB - Objective: Keeping in mind the rising prevalence of nonalcoholic fatty liver disease (NAFLD) and the need to establish noninvasive tests for its detection, the aim of our study was to investigate whether platelet count (PC), mean platelet volume (MPV), and platelet distribution width (PDW) can predict the presence of liver fibrosis in this group of patients. Methods: In 98 patients with NAFLD and 60 healthy volunteers, complete blood counts with automated differential counts were performed and values of PC, PDW, MPV, and PCT were analyzed. Results: Patients with NAFLD had lower PC and higher MPV, PCT, and PDW compared to the controls (P < 0.05). When NAFLD group was stratified according to severity of liver fibrosis, there was a statistically significant difference in the average values of PDW and PC between the groups (P < 0.05). Conclusion: Patients with NAFLD have significantly higher values of PCT, PDW, and MPV when compared to the healthy controls. Further studies are needed to establish their potential use for prediction of the degree of liver steatosis and fibrosis in NAFLD patients. PMID- 29464179 TI - Leukocyte Cell-Derived Chemotaxin 2-Associated Renal Amyloidosis: A Case Report. AB - Amyloidosis is a disorder characterized by the deposition of abnormal protein fibrils in tissues. Leukocyte cell-derived chemotaxin 2-associated amyloidosis is a recently recognized entity and is characterized by a distinctive clinicopathologic type of amyloid deposition manifested in adults by varying degrees of impaired kidney function and proteinuria. There are only a limited number of cases reported in the literature. We present a 64-year-old Hispanic female with a history of hypertension who was referred for chronic kidney disease management. The review of her laboratory tests revealed a serum creatinine of 1.5 1.8 mg/dL and microalbuminuria (in the presence of a bland urine sediment) in the past year. She denied any history of diabetes, rheumatologic disorders or exposure to intravenous contrast, nonsteroidal anti-inflammatory drugs, herbals, and heavy metals. Serological workup was negative. A renal biopsy showed diffuse infiltration of glomerulus with pale eosinophilic material strongly positive for Congo red stain and a similar eosinophilic material in the interstitium, muscular arteries, and arterioles. Electron microscopy showed marked infiltration of the mesangium, capillary loops, and interstitium with haphazardly arranged fibrillary deposits (9.8 nm thick). Liquid chromatography tandem mass spectrometry confirmed leukocyte cell-derived chemotaxin 2 (LECT2) amyloid deposition. LECT2 amyloidosis (ALECT2) should be suspected in renal biopsy specimens exhibiting extensive and strong mesangial as well as interstitial congophilia. Individuals with LECT2 renal amyloidosis have a varying prognosis. Therapeutic options include supportive measures and consideration of a kidney transplant for those with end stage renal disease. PMID- 29464180 TI - Lingguizhugan Decoction Protects against High-Fat-Diet-Induced Nonalcoholic Fatty Liver Disease by Alleviating Oxidative Stress and Activating Cholesterol Secretion. AB - Background: Nonalcoholic fatty liver disease (NAFLD) has become a leading cause of liver transplantation. Lingguizhugan decoction (LGZG), a classical Chinese herbal formula, has beneficial effects on NAFLD animal models. Our study examined the impact of LGZG on hepatic global transcriptome of high-fat-diet-induced NAFLD rats. Methods: Three groups of Wistar rats were included: normal, NAFLD model, and LGZG-treated NAFLD groups. Four weeks for the treatment, liver tissues were harvested for RNA sequencing. Differentially expressed genes (DEGs) and enriched pathways were detected on hepatic global transcriptome profile. Real-time PCR validated the regulatory patterns of LGZG on NAFLD rats. Results: DEGs between the NAFLD model and normal groups indicated the elevated peroxisome proliferator activated receptor (PPAR) and hedgehog signaling pathways in NAFLD rats. In bile secretion pathway, genes involved in cholesterol secretion were activated by LGZG treatment. Increased expression of antioxidant OSIGN1 and decreased expression of genes (AHR, IRF2BP2, and RASGEF1B) that induce oxidative stress and inflammation were observed in NAFLD rats treated with LGZG. The regulatory patterns of LGZG treatment on these oxidative stress-related genes were confirmed by real-time PCR. Conclusion: Our study revealed a "two-hits-targeting" mechanism of LGZG in the treatment for NAFLD: alleviating oxidative stress and activating cholesterol secretion. PMID- 29464181 TI - Diabetic Retinopathy in the Spontaneously Diabetic Torii Rat: Pathogenetic Mechanisms and Preventive Efficacy of Inhibiting the Urokinase-Type Plasminogen Activator Receptor System. AB - The spontaneously diabetic Torii (SDT) rat is of increasing preclinical interest because of its similarities to human type 2 diabetic retinopathy (DR). The system formed by urokinase-type plasminogen activator (uPA) and its receptor (uPAR) is a player in blood-retinal barrier (BRB) breakdown in DR. Here, we investigated whether in SDT rats, preventive administration of UPARANT, an inhibitor of the uPAR pathway, counteracts the retinal impairment in response to chronic hyperglycemia. Electroretinogram (ERG) monitoring was followed over time. Fluorescein-dextran microscopy, CD31 immunohistochemistry, quantitative PCR, ELISA, Evans blue perfusion, and Western blot were also used. UPARANT prevented ERG dysfunction, upregulation of vascular endothelial growth factor and fibroblast growth factor-2, BRB leakage, gliosis, and retinal cell death. The mechanisms underlying UPARANT benefits were studied comparing them with the acute streptozotocin (STZ) model in which UPARANT is known to inhibit DR signs. In SDT rats, but not in the STZ model, UPARANT downregulated the expression of uPAR and its membrane partners. In both models, UPARANT reduced the levels of transcription factors coupled to inflammation or inflammatory factors themselves. These findings may help to establish the uPAR system as putative target for the development of novel drugs that may prevent type 2 DR. PMID- 29464182 TI - Association between Knowledge-Attitude-Practices and Control of Blood Glucose, Blood Pressure, and Blood Lipids in Patients with Type 2 Diabetes in Shanghai, China: A Cross-Sectional Study. AB - Knowledge-attitude-practices (KAP) significantly impact the outcome of self management in patients with diabetes, yet the association between KAP and the combined control of the levels of blood glucose, blood pressure, and blood lipids in these patients remains uncertain. This community-based cross-sectional study was conducted from December 2014 to December 2016 on 3977 patients with type 2 diabetes in Shanghai. KAP were evaluated using the modified Chinese version of the Diabetes, Hypertension and Hyperlipidemia (DHL) Knowledge Instrument, Diabetes Empowerment Scale-Short Form (DES-SF), and Summary of Diabetes Self-Care Activities (SDSCA). Clinical and biochemical measurements were performed at each sampling site. The association between KAP scores and achieving the combined target goal was assessed by multiple logistic regression. Patients having a higher score of knowledge were more likely to achieve the combined target goal. Furthermore, a turning point of knowledge score was found that the possibility of achieving the combined target goal presented a sharp increase when the knowledge score was more than 70. However, the scores of attitude and practices had no significant relations with achieving the combined target goal. Health intervention strategies, especially increasing integrated diabetes knowledge, should be targeted to patients with type 2 diabetes in communities. PMID- 29464183 TI - The Involvement of Notch1-RBP-Jk/Msx2 Signaling Pathway in Aortic Calcification of Diabetic Nephropathy Rats. AB - Background: This study explored the changes in expression of vascular smooth muscle cell (VSMC) markers and osteogenic markers, as well as the involvement of Notch1-RBP-Jk/Msx2 pathway in a rat model of diabetic nephropathy (DN) with vascular calcification. Methods: A rat model of DN with concomitant vascular calcification was created by intraperitoneal injection of streptozotocin followed by administration of vitamin D3 and nicotine. Biochemical analysis and histological examination of aortic tissue were performed. VSMC markers and osteogenic markers as well as target molecules in Notch1-RBP-Jk/Msx2 were determined by quantitative real-time polymerase chain reaction and immunohistochemical analysis. Results: Serum calcium and phosphorus levels were significantly increased in model rats as compared to that in normal controls. Diabetic rats with vascular calcification exhibited mineral deposits in aortic intima-media accompanied by decreased expression of VSMC markers and increased expression of osteogenic markers. Notch1, RBP-Jk, Msx2, Jagged1, and N1-ICD were barely expressed in the aortic wall of normal rats. In contrast, these were significantly increased in the model group at all time points (8, 12, and 16 weeks), as compared to that in the normal rats. Conclusion: Activation of the Notch1-RBP-Jk/Msx2 signaling pathway may be involved in the development and progression of vascular calcification in DN. PMID- 29464184 TI - Lysosomal Exoglycosidase Profile and Secretory Function in the Salivary Glands of Rats with Streptozotocin-Induced Diabetes. AB - Before this study, there had been no research evaluating the relationship between a lysosomal exoglycosidase profile and secretory function in the salivary glands of rats with streptozotocin- (STZ-) induced type 1 diabetes. In our work, rats were divided into 4 groups of 8 animals each: control groups (C2, C4) and diabetic groups (STZ2, STZ4). The secretory function of salivary glands nonstimulated and stimulated salivary flow, alpha-amylase, total protein-and salivary exoglycosidase activities-N-acetyl-beta-hexosaminidase (HEX, HEX A, and HEX B), beta-glucuronidase, alpha-fucosidase, beta-galactosidase, and alpha mannosidase-was estimated both in the parotid and submandibular glands of STZ diabetic and control rats. The study has demonstrated that the activity of most salivary exoglycosidases is significantly higher in the parotid and submandibular glands of STZ-diabetic rats as compared to the healthy controls and that it increases as the disease progresses. Reduced secretory function of diabetic salivary glands was also observed. A significant inverse correlation between HEX B, alpha-amylase activity, and stimulated salivary flow in diabetic parotid gland has also been shown. Summarizing, STZ-induced diabetes leads to a change in the lysosomal exoglycosidase profile and reduced function of the salivary glands. PMID- 29464185 TI - Performance Characteristics of Different Anti-Double-Stranded DNA Antibody Assays in the Monitoring of Systemic Lupus Erythematosus. AB - Objective: We sought to evaluate different anti-double-stranded DNA assays for their performance characteristics in monitoring disease activity fluctuations in systemic lupus erythematosus (SLE). Methods: 36 active SLE patients were followed monthly. At each study visit (total n = 371), blood was collected and disease activity was scored using the SELENA-SLEDAI (excluding anti-dsDNA or complement components) and by a physician's global assessment (PGA). Four anti-dsDNA tests were compared. Linear mixed-effects models with random intercept and fixed slopes were used to evaluate the relationship between the longitudinal fluctuations of disease activity and anti-dsDNA titers. Results: At enrollment, positivity for QUANTA Lite and high-avidity anti-dsDNA assay was both 64% and significantly lower than anti-dsDNA positivity by QUANTA Flash (83%) and CLIFT (96%). Linear mixed-effects modeling indicated that the change in clinical SELENA-SLEDAI scores was associated with the titers of all anti-dsDNA with QUANTA Flash yielding the highest marginal R2 (0.15; p < 0.01). QUANTA Flash was the only anti-dsDNA assay significantly associated with the change in PGA (marginal R2 = 0.05; p < 0.01). Conclusion: These data indicate that anti-dsDNA antibodies determined by QUANTA Flash have a value in monitoring SLE disease activity. PMID- 29464186 TI - Exemestane Attenuates Hepatic Fibrosis in Rats by Inhibiting Activation of Hepatic Stellate Cells and Promoting the Secretion of Interleukin 10. AB - Exemestane (EXE) is an irreversible steroidal aromatase inhibitor mainly used as an adjuvant endocrine therapy for postmenopausal women suffering from breast cancer. Besides inhibiting aromatase activity, EXE has multiple biological functions, such as antiproliferation, anti-inflammatory, and antioxidant activities which are all involved in hepatic fibrosis. Therefore, we investigated the role of EXE during the progress of hepatic fibrosis. The effect of EXE on liver injury and fibrosis were assessed in two hepatic fibrosis rat models, which were induced by either carbon tetrachloride (CCl4) or bile duct ligation (BDL). The influence of EXE treatment on activation and proliferation of primary rat hepatic stellate cells (HSCs) was observed in vitro. The results showed that EXE attenuated the liver fibrosis by decreasing the collagen deposition and alpha-SMA expression in vivo and inhibited the activation and proliferation of primary rat HSCs in vitro. Additionally, EXE promoted the secretion of antifibrotic and anti inflammatory cytokine IL-10 in vivo and in HSC-T6 culture media. In conclusion, our findings reveal a new function of EXE on hepatic fibrosis and prompted its latent application in liver fibrotic-related disease. PMID- 29464187 TI - Nanoscale diffractive probing of strain dynamics in ultrafast transmission electron microscopy. AB - The control of optically driven high-frequency strain waves in nanostructured systems is an essential ingredient for the further development of nanophononics. However, broadly applicable experimental means to quantitatively map such structural distortion on their intrinsic ultrafast time and nanometer length scales are still lacking. Here, we introduce ultrafast convergent beam electron diffraction with a nanoscale probe beam for the quantitative retrieval of the time-dependent local deformation gradient tensor. We demonstrate its capabilities by investigating the ultrafast acoustic deformations close to the edge of a single-crystalline graphite membrane. Tracking the structural distortion with a 28-nm/700-fs spatio-temporal resolution, we observe an acoustic membrane breathing mode with spatially modulated amplitude, governed by the optical near field structure at the membrane edge. Furthermore, an in-plane polarized acoustic shock wave is launched at the membrane edge, which triggers secondary acoustic shear waves with a pronounced spatio-temporal dependency. The experimental findings are compared to numerical acoustic wave simulations in the continuous medium limit, highlighting the importance of microscopic dissipation mechanisms and ballistic transport channels. PMID- 29464188 TI - Glycine receptor modulating antibody predicting treatable stiff-person spectrum disorders. AB - Background: Glycine receptor alpha-1 subunit (GlyRalpha1)-immunoglobulin G (IgG) is diagnostic of stiff-person syndrome (SPS) spectrum but has been reported detectable in other neurologic diseases for which significance is less certain. Methods: To assess GlyRalpha1-IgGs as biomarkers of SPS spectrum among patients and controls, specimens were tested using cell-based assays (binding [4 degrees C] and modulating [antigen endocytosing, 37 degrees C]). Medical records of seropositive patients were reviewed. Results: GlyRalpha1-IgG (binding antibody) was detected in 21 of 247 patients with suspected SPS spectrum (8.5%) and in 8 of 190 healthy subject sera (4%) but not CSF. Among 21 seropositive patients, 20 had confirmed SPS spectrum clinically, but 1 was later determined to have a functional neurologic disorder. Sera from 9 patients with SPS spectrum , but not 7 controls, nor the functional patient, caused GlyRalpha1 modulation (100% specificity). SPS spectrum phenotypes included progressive encephalomyelitis with rigidity and myoclonus (PERM) (8), classic SPS (5), stiff limb (5), stiff trunk (1), and isolated exaggerated startle (hyperekplexia, 1). Neuropsychiatric symptoms present in 12 patients (60%) were anxiety (11), depression (6), and delirium (3). Anxiety was particularly severe in 3 patients with PERM. Objective improvements in SPS neurologic symptoms were recorded in 16 of 18 patients who received first-line immunotherapy (89%, 9/10 treated with corticosteroids, 8/10 treated with IVIg, 3/4 treated with plasma exchange, and 1 treated with rituximab). Treatment-sparing maintenance strategies were successful in 4 of 7 patients (rituximab [2/3], azathioprine [1/1], and mycophenolate [1/3]). Conclusions: GlyRalpha1-modulating antibody improves diagnostic specificity for immunologically treatable SPS spectrum disorders. Classification of evidence: This study provides Class IV evidence that GlyRalpha1-modulating antibody accurately identifies patients with treatable SPS spectrum disorders. PMID- 29464189 TI - Achievements of Diabetes Goals and Their Determinants in Type 2 Diabetic Patients Attending Outpatient Diabetic Clinic in Northern Ethiopia. AB - Background: The aim of this study was to assess target diabetic goal achievements and to explore variables associated with them. Methods: A cross-sectional study was conducted between December 2015 and April 2016 on 188 type 2 diabetic patients attending Ayder Referral Hospital's outpatient diabetic clinic. Glycemic control was assessed using fasting plasma glucose values and total cholesterol and triglyceride were used to evaluate lipid profiles. Bivariate and multivariate logistic regression analyses were done to identify factors associated with poor glycemic control, hypertension, and dyslipidemia. Result: Mean duration of diabetes was 6.5 years. Combined glycemic, lipid, and blood pressure targets were achieved only in 8.5% of the participants. More males achieved combined targets than females. Separately, while above two-thirds of the patients had poor glycemic control (67%), more than half of the participants have had poor lipid (58.5%) and blood pressure (52.1%) control. A significant portion of the patients (68.1%) had also comorbidities other than hyperglycemia. In bivariate and multivariate analyses, longer duration of diabetes disease (AOR: 3.4; P = 0.013) and marked month to month fasting plasma glucose (FPG) variability as measured by large standard deviation (AOR: 2.5; P = 0.023) were significantly associated with overall poor mean FPG results. Female sex was also significantly associated with dyslipidemia (AOR: 1.9; P = 0.049). Conclusion: The study showed that achievements of combined diabetic goals are generally poor. PMID- 29464190 TI - Identification of Neurotensin Receptor Expressing Cells in the Ventral Tegmental Area across the Lifespan. AB - Neurotensin (Nts) promotes activation of dopamine (DA) neurons in the ventral tegmental area (VTA) via incompletely understood mechanisms. Nts can signal via the G protein-coupled Nts receptors 1 and 2 (NtsR1 and NtsR2), but the lack of methods to detect NtsR1- and NtsR2-expressing cells has limited mechanistic understanding of Nts action. To overcome this challenge, we generated dual recombinase mice that express FlpO-dependent Cre recombinase in NtsR1 or NtsR2 cells. This strategy permitted temporal control over recombination, such that we could identify NtsR1- or NtsR2-expressing cells and determine whether their distributions differed between the developing and adult brain. Using this system, we found that NtsR1 is transiently expressed in nearly all DA neurons and in many non-DA neurons in the VTA during development. However, NtsR1 expression is more restricted within the adult brain, where only two thirds of VTA DA neurons expressed NtsR1. By contrast, NtsR2 expression remains constant throughout lifespan, but it is predominantly expressed within glia. Anterograde tract tracing revealed that NtsR1 is expressed by mesolimbic, not mesocortical DA neurons, suggesting that VTA NtsR1 neurons may represent a functionally unique subset of VTA DA neurons. Collectively, this work reveals a cellular mechanism by which Nts can directly engage NtsR1-expressing DA neurons to modify DA signaling. Going forward, the dual recombinase strategy developed here will be useful to selectively modulate NtsR1- and NtsR2-expressing cells and to parse their contributions to Nts-mediated behaviors. PMID- 29464191 TI - Impact of NMDA Receptor Overexpression on Cerebellar Purkinje Cell Activity and Motor Learning. AB - In many brain regions involved in learning NMDA receptors (NMDARs) act as coincidence detectors of pre- and postsynaptic activity, mediating Hebbian plasticity. Intriguingly, the parallel fiber (PF) to Purkinje cell (PC) input in the cerebellar cortex, which is critical for procedural learning, shows virtually no postsynaptic NMDARs. Why is this? Here, we address this question by generating and testing independent transgenic lines that overexpress NMDAR containing the type 2B subunit (NR2B) specifically in PCs. PCs of the mice that show larger NMDA mediated currents than controls at their PF input suffer from a blockage of long term potentiation (LTP) at their PF-PC synapses, while long-term depression (LTD) and baseline transmission are unaffected. Moreover, introducing NMDA-mediated currents affects cerebellar learning in that phase-reversal of the vestibulo ocular reflex (VOR) is impaired. Our results suggest that under physiological circumstances PC spines lack NMDARs postsynaptically at their PF input so as to allow LTP to contribute to motor learning. PMID- 29464192 TI - Specific Relationship between the Shape of the Readiness Potential, Subjective Decision Time, and Waiting Time Predicted by an Accumulator Model with Temporally Autocorrelated Input Noise. AB - Self-initiated movements are reliably preceded by a gradual buildup of neuronal activity known as the readiness potential (RP). Recent evidence suggests that the RP may reflect subthreshold stochastic fluctuations in neural activity that can be modeled as a process of accumulation to bound. One element of accumulator models that has been largely overlooked in the literature is the stochastic term, which is traditionally modeled as Gaussian white noise. While there may be practical reasons for this choice, we have long known that noise in neural systems is not white - it is long-term correlated with spectral density of the form 1/fbeta(with roughly 1 < beta < 3) across a broad range of spatial scales. I explored the behavior of a leaky stochastic accumulator when the noise over which it accumulates is temporally autocorrelated. I also allowed for the possibility that the RP, as measured at the scalp, might reflect the input to the accumulator (i.e., its stochastic noise component) rather than its output. These two premises led to two novel predictions that I empirically confirmed on behavioral and electroencephalography data from human subjects performing a self-initiated movement task. In addition to generating these two predictions, the model also suggested biologically plausible levels of autocorrelation, consistent with the degree of autocorrelation in our empirical data and in prior reports. These results expose new perspectives for accumulator models by suggesting that the spectral properties of the stochastic input should be allowed to vary, consistent with the nature of biological neural noise.

AB - Repetitive transcranial magnetic stimulation (rTMS) induces plasticity in normal and abnormal neural circuitries, an effect that may be influenced by intrinsic brain activity during treatment. Here, we study potential synergistic effects between low-intensity rTMS (LI-rTMS) and concurrent neural activity in promoting circuit reorganization and enhancing visual behavior. We used ephrin-A2A5-/- mice, which are known to possess visuotopic mapping errors that are ameliorated by LI-rTMS, and assessed the impact of stimulation when mice were engaged in a visual learning task. A detachable coil was affixed to each mouse, and animals underwent 2 wk of 10-min daily training in a two-choice visual discrimination task with concurrent LI-rTMS or sham stimulation. No-task controls (+LI rTMS/sham) were placed in the task arena without visual task training. At the end of the experiment, visuomotor tracking behavior was assessed, and corticotectal and geniculocortical pathway organization was mapped by injections of fluorescent tracers into the primary visual cortex. Consistent with previous results, LI-rTMS alone improved geniculocortical and corticotectal topography, but combining LI rTMS with the visual learning task prevented beneficial corticotectal reorganization and had no additional effect on geniculocortical topography or visuomotor tracking performance. Unexpectedly, there was a significant increase in the total number of trials completed by task + LI-rTMS mice in the visual learning task. Comparison with wild-type mice revealed that ephrin-A2A5-/- mice had reduced accuracy and response rates, suggesting a goal-directed behavioral deficit, which was improved by LI-rTMS. Our results suggest that concurrent brain activity during behavior interacts with LI-rTMS, altering behavior and different visual circuits in an abnormal system. PMID- 29464194 TI - Identification of Two Distinct Working Memory-Related Brain Networks in Healthy Young Adults. AB - Working memory (WM) is an important cognitive domain for everyday life functioning and is often disturbed in neuropsychiatric disorders. Functional magnetic resonance imaging (fMRI) studies in humans show that distributed brain areas typically described as fronto-parietal regions are implicated in WM tasks. Based on data from a large sample of healthy young adults (N = 1369), we applied independent component analysis (ICA) to the WM-fMRI signal and identified two distinct networks that were relevant for differences in individual WM task performance. A parietally-centered network was particularly relevant for individual differences in task measures related to WM performance ("WM dependent") and a frontally-centered network was relevant for differences in attention-dependent task performance. Importantly, frontal areas that are typically considered as key regions for WM were either involved in both WM dependent and attention-dependent performance, or in attention-dependent performance only. The networks identified here are provided as publicly available datasets. These networks can be applied in future studies to derive a low dimensional representation of the overall WM brain activation. PMID- 29464195 TI - Danger Changes the Way the Mammalian Brain Stores Information About Innocuous Events: A Study of Sensory Preconditioning in Rats. AB - The amygdala is a critical substrate for learning about cues that signal danger. Less is known about its role in processing innocuous or background information. The present study addressed this question using a sensory preconditioning protocol in male rats. In each experiment, rats were exposed to pairings of two innocuous stimuli in stage 1, S2 and S1, and then to pairings of S1 and shock in stage 2. As a consequence of this training, control rats displayed defensive reactions (freezing) when tested with both S2 and S1. The freezing to S2 is a product of two associations formed in training: an S2-S1 association in stage 1 and an S1-shock association in stage 2. We examined the roles of two medial temporal lobe (MTL) structures in consolidation of the S2-S1 association: the perirhinal cortex (PRh) and basolateral complex of the amygdala (BLA). When the S2-S1 association formed in a safe context, its consolidation required neuronal activity in the PRh (but not BLA), including activation of AMPA receptors and MAPK signaling. In contrast, when the S2-S1 association formed in a dangerous context, or when the context was rendered dangerous immediately after the association had formed, its consolidation required neuronal activity in the BLA (but not PRh), including activation of AMPA receptors and MAPK signaling. These roles of the PRh and BLA show that danger changes the way the mammalian brain stores information about innocuous events. They are discussed with respect to danger-induced changes in stimulus processing. PMID- 29464196 TI - Sequences Flanking the Gephyrin-Binding Site of GlyRbeta Tune Receptor Stabilization at Synapses. AB - The efficacy of synaptic transmission is determined by the number of neurotransmitter receptors at synapses. Their recruitment depends upon the availability of postsynaptic scaffolding molecules that interact with specific binding sequences of the receptor. At inhibitory synapses, gephyrin is the major scaffold protein that mediates the accumulation of heteromeric glycine receptors (GlyRs) via the cytoplasmic loop in the beta-subunit (beta-loop). This binding involves high- and low-affinity interactions, but the molecular mechanism of this bimodal binding and its implication in GlyR stabilization at synapses remain unknown. We have approached this question using a combination of quantitative biochemical tools and high-density single molecule tracking in cultured rat spinal cord neurons. The high-affinity binding site could be identified and was shown to rely on the formation of a 310-helix C-terminal to the beta-loop core gephyrin-binding motif. This site plays a structural role in shaping the core motif and represents the major contributor to the synaptic confinement of GlyRs by gephyrin. The N-terminal flanking sequence promotes lower affinity interactions by occupying newly identified binding sites on gephyrin. Despite its low affinity, this binding site plays a modulatory role in tuning the mobility of the receptor. Together, the GlyR beta-loop sequences flanking the core-binding site differentially regulate the affinity of the receptor for gephyrin and its trapping at synapses. Our experimental approach thus bridges the gap between thermodynamic aspects of receptor-scaffold interactions and functional receptor stabilization at synapses in living cells. PMID- 29464197 TI - MeCP2 Deficiency Leads to Loss of Glial Kir4.1. AB - Rett syndrome (RTT) is an X-linked neurodevelopmental disorder usually caused by mutations in methyl-CpG-binding protein 2 (MeCP2). RTT is typified by apparently normal development until 6-18 mo of age, when motor and communicative skills regress and hand stereotypies, autonomic symptoms, and seizures present. Restoration of MeCP2 function selectively to astrocytes reversed several deficits in a murine model of RTT, but the mechanism of this rescue is unknown. Astrocytes carry out many essential functions required for normal brain functioning, including extracellular K+ buffering. Kir4.1, an inwardly rectifying K+ channel, is largely responsible for the channel-mediated K+ regulation by astrocytes. Loss of-function mutations in Kir4.1 in human patients result in a severe neurodevelopmental disorder termed EAST or SESAME syndrome. Here, we evaluated astrocytic Kir4.1 expression in a murine model of Rett syndrome. We demonstrate by chromatin immunoprecipitation analysis that Kir4.1 is a direct molecular target of MeCP2. Astrocytes from Mecp2-deficient mice express significantly less Kir4.1 mRNA and protein, which translates into a >50% deficiency in Ba2+ sensitive Kir4.1-mediated currents, and impaired extracellular potassium dynamics. By examining astrocytes in isolation, we demonstrate that loss of Kir4.1 is cell autonomous. Assessment through postnatal development revealed that Kir4.1 expression in Mecp2-deficient animals never reaches adult, wild-type levels, consistent with a neurodevelopmental disorder. These are the first data implicating a direct MeCP2 molecular target in astrocytes and provide novel mechanistic insight explaining a potential mechanism by which astrocytic dysfunction may contribute to RTT. PMID- 29464199 TI - Immunosuppression Adherence in Stable Kidney Transplant Patients Converted From Immediate- to Prolonged-Release Tacrolimus in Clinical Practice: A Norwegian Study. AB - Background: This study investigated medication adherence in kidney transplant patients (KTPs) converted from immediate-release tacrolimus (IR-T) to prolonged release tacrolimus (PR-T)-based immunosuppression in routine practice. Methods: Noninterventional, observational, multicenter study in Norway. Included adult KTPs with stable graft function, converted from IR-T (baseline) to PR-T (1 mg:1 mg) in routine practice. Data were collected at baseline, and months 1, 3, 6, and 12 postconversion. Primary endpoint: adherence using the Basel Assessment of Adherence to Immunosuppressive Medication Scale. Secondary assessments: tacrolimus dose and trough levels (target, 3-7 ng/mL), clinical laboratory parameters (eg, estimated glomerular filtration rate [Modified Diet in Renal Disease]), and adverse events. Results: Ninety-one KTPs (mean +/- SD age 47.7 +/- 14.3 years) were analyzed. Mean +/- SD change in PR-T dose from baseline (4.4 +/- 2.4 mg/d) to month 12 was -0.1 +/- 0.9 mg/d; mean tacrolimus trough levels remained within target. Overall medication adherence increased from 45.6% at baseline to 58.1% at month 1, but was similar to baseline thereafter; taking and timing adherence followed a similar pattern. Odds ratio (OR) for adherence at month 1 (but not at other time points) was greater versus baseline for overall (OR, 1.71; P = 0.0205), taking (OR, 3.38; P = 0.0004), and timing (OR, 1.77, P = 0.0252) dimensions. Mean +/- SD Basel Assessment of Adherence to Immunosuppressive Medication Scale visual analogue scale score at baseline was 96.4 +/- 5.5%, and increased postconversion. Estimated glomerular filtration rate remained stable (month 12, 61.6 +/- 17.7 mL/min per 1.73 m2), as did other laboratory parameters. Two (2.2%) patients had adverse events considered probably/possibly treatment-related. Conclusions: There was disparity between high, patient-perceived and low, actual adherence. Converting stable KTPs from IR T to PR-T in routine practice did not impact long-term adherence to immunosuppression; renal function remained stable. PMID- 29464198 TI - Unraveling Synaptic GCaMP Signals: Differential Excitability and Clearance Mechanisms Underlying Distinct Ca2+ Dynamics in Tonic and Phasic Excitatory, and Aminergic Modulatory Motor Terminals in Drosophila. AB - GCaMP is an optogenetic Ca2+ sensor widely used for monitoring neuronal activities but the precise physiological implications of GCaMP signals remain to be further delineated among functionally distinct synapses. The Drosophila neuromuscular junction (NMJ), a powerful genetic system for studying synaptic function and plasticity, consists of tonic and phasic glutamatergic and modulatory aminergic motor terminals of distinct properties. We report a first simultaneous imaging and electric recording study to directly contrast the frequency characteristics of GCaMP signals of the three synapses for physiological implications. Different GCaMP variants were applied in genetic and pharmacological perturbation experiments to examine the Ca2+ influx and clearance processes underlying the GCaMP signal. Distinct mutational and drug effects on GCaMP signals indicate differential roles of Na+ and K+ channels, encoded by genes including paralytic (para), Shaker (Sh), Shab, and ether-a-go-go (eag), in excitability control of different motor terminals. Moreover, the Ca2+ handling properties reflected by the characteristic frequency dependence of the synaptic GCaMP signals were determined to a large extent by differential capacity of mitochondria-powered Ca2+ clearance mechanisms. Simultaneous focal recordings of synaptic activities further revealed that GCaMPs were ineffective in tracking the rapid dynamics of Ca2+ influx that triggers transmitter release, especially during low-frequency activities, but more adequately reflected cytosolic residual Ca2+ accumulation, a major factor governing activity-dependent synaptic plasticity. These results highlight the vast range of GCaMP response patterns in functionally distinct synaptic types and provide relevant information for establishing basic guidelines for the physiological interpretations of presynaptic GCaMP signals from in situ imaging studies. PMID- 29464200 TI - Polyomavirus BK Nephropathy-Associated Transcriptomic Signatures: A Critical Reevaluation. AB - Background: Recent work using DNA microarrays has suggested that genes related to DNA replication, RNA polymerase assembly, and pathogen recognition receptors can serve as surrogate tissue biomarkers for polyomavirus BK nephropathy (BKPyVN). Methods: We have examined this premise by looking for differential regulation of these genes using a different technology platform (RNA-seq) and an independent set 25 biopsies covering a wide spectrum of diagnoses. Results: RNA-seq could discriminate T cell-mediated rejection from other common lesions seen in formalin fixed biopsy material. However, overlapping RNA-seq signatures were found among all disease processes investigated. Specifically, genes previously reported as being specific for the diagnosis of BKPyVN were found to be significantly upregulated in T cell-mediated rejection, inflamed areas of fibrosis/tubular atrophy, as well as acute tubular injury. Conclusions: In conclusion, the search for virus specific molecular signatures is confounded by substantial overlap in pathogenetic mechanisms between BKPyVN and nonviral forms of allograft injury. Clinical heterogeneity, overlapping exposures, and different morphologic patterns and stage of disease are a source of substantial variability in "Omics" experiments. These variables should be better controlled in future biomarker studies on BKPyVN, T cell-mediated rejection, and other forms of allograft injury, before widespread implementation of these tests in the transplant clinic. PMID- 29464201 TI - Prediction of Early BK Virus Infection in Kidney Transplant Recipients by the Number of Cells With Intranuclear Inclusion Bodies (Decoy Cells). AB - Background: BK virus (BKV) is the cause of nephropathy. Because BKV nephropathy can progress to graft loss, early diagnosis of BKV infection is very important. In this study, we aimed to investigate the utility of quantifying cells with intranuclear inclusion bodies (decoy cells) in urinary sediment for the screening and monitoring of BKV infection in renal transplant recipients at our hospital. Methods: This was a retrospective single-center study. Urine sediment examination was performed at each outpatient visit, and the number of decoy cells was measured in the whole microscopic field. Patients (n = 41) were divided into the BK viremia group (blood positive for BKV DNA by polymerase chain reaction [PCR]) and non-BK viremia group (blood negative for BKV DNA by PCR), and the decoy cell count in urinary sediments was examined. Results: The maximum decoy cell count was significantly higher (P = 0.04) in the BK viremia group than in the non-BK viremia group. In the receiver operating characteristic curve for the maximum decoy cells, the cutoff value was 507 cells. The area under the receiver operating characteristic curve was 0.8774 (95% confidence interval, 0.7739 0.9810). The number of decoy cells at the time of appearance in the BK viremia group was not significantly different from that in the non-BK viremia group. However, the BK viremia group showed an increasing trend, whereas the non-BK viremia group showed a decreasing trend, in the number of decoy cells. There was a positive correlation between the number of decoy cells and the data from the urine BKV-DNA PCR quantification (correlation coefficient [r] = 0.74). Conclusions: Measurement of decoy cells in urinary sediments may predict early BKV infection, and if performed quickly, it may be useful for screening and continuous monitoring of BKV infection in renal transplant recipients. PMID- 29464202 TI - Prevalence and Clinical Correlates of Chronic Hepatitis E Infection in German Renal Transplant Recipients With Elevated Liver Enzymes. AB - Background: Elevated liver enzymes are frequently observed in renal transplant recipients and warrant further exploration. In immunosuppressed patients, hepatitis E virus (HEV) infection may cause chronic hepatitis, cirrhosis, and extrahepatic manifestations such as renal injury. Methods: We performed a retrospective cross-sectional study investigating the prevalence, clinical correlates, and outcome of chronic HEV infection in a cohort of renal transplant recipients with elevated liver enzymes. Results: Over a period of 30 months, 140 of 1469 renal transplant recipients had elevated liver enzymes, of which serum samples from 98 patients were available to determine HEV status. Seventeen patients were detected with HEV infection, of which 16 developed chronic HEV infection, while 1 patient controlled viremia (prevalence of chronic infection of 16.3%, with a minimum prevalence of 1.1% in the whole cohort). Increased liver stiffness was indicated by an average FibroScan result of 11.2 kPa in these patients. All 16 patients with chronic HEV infection were treated with ribavirin for a mean duration of 3 months. Five patients developed a viral rebound and received a second treatment course, of which 2 controlled HEV replication. Six months after the end of therapy, HEV clearance was achieved in 81.3% of the patients. One patient developed ribavirin resistance. Hemolytic anemia after ribavirin treatment was frequent, requiring blood transfusion in 3 patients. Four patients developed de novo glomerulonephritis, of which 2 were possibly associated with HEV infection. Conclusions: This retrospective study showed that prevalence of chronic HEV infection was high in our renal transplant patient cohort and was associated with significant liver impairment and the occurrence of renal injury. Ribavirin treatment was effective and should be initiated early to avoid complications, but the risk of severe hemolytic anemia makes strict monitoring essential. PMID- 29464203 TI - Rituximab Induction to Prevent the Recurrence of PSC After Liver Transplantation The Lessons Learned From ABO-Incompatible Living Donor Liver Transplantation. AB - Background: Multiple studies have failed to reveal an effective method for preventing the recurrence of primary sclerosing cholangitis (PSC) after liver transplantation (LTx). A national study conducted in Japan revealed several risk factors for the recurrence after living donor LTx (LDLTx); however, recipients of ABO-blood type incompatible (ABO-I) LTx were excluded from the previous analysis. In the present study, we investigated the efficacy of an immunosuppressive protocol in ABO-I LTx on the recurrence of PSC after LDLTx. Methods: We conducted a national survey and analyzed the outcome of recipients who underwent ABO-I LDLTx for PSC (n = 12) between 1994 and 2010 in 9 centers and compared the outcome with that of ABO-compatible LDLTx for PSC (n = 96). The key elements of the immunosuppressive regimen in ABO-I LTx are plasma exchange sessions to remove existing antibodies, and the use of immunosuppression to control humoral immunity. Rituximab was added to the immunosuppression regimen from 2006 onward; 5 patients received rituximab perioperatively. Results: All 7 recipients who underwent ABO-I LDLTx before 2006 (who did not receive rituximab) died of infection (n = 3), antibody-mediated rejection (n = 1), ABO-incompatibility associated cholangiopathy (n = 1) or recurrence of PSC (n = 2). In contrast, we found that all 5 recipients from 2006 (who were treated with rituximab) retained an excellent graft function for more than 7 years without any recurrence of PSC. Conclusions: The findings of this study shed light on the efficacy of a novel strategy to prevent the recurrence of PSC and the possible mechanisms provided by rituximab treatment are discussed. PMID- 29464204 TI - Tailored Rabbit Antithymocyte Globulin Induction Dosing for Kidney Transplantation. AB - Background: Rabbit antithymocyte globulin (rATG) is the most widely used kidney transplant induction immunotherapy in the United States. It was recently Food and Drug Administration approved for this indication with typical dose recommendations of 1.5 mg/kg for up to 7 days given via a central line. Methods: We theorized that reduced rATG dosing when compared with conventional dosing (6 10.5 mg/kg) is safe and effective, leading to development of a risk-stratified treatment protocol. Five-year data from a retrospective cohort of 224 adult kidney transplants (2008-2013) with follow-up through 2015 is presented. Cumulative rATG doses of 3 mg/kg were administered peripherally to nonsensitized living donor recipients, 4.5 mg/kg to nonsensitized deceased donor recipients. A subset of higher immunologic risk recipients (defined as history of prior transplant, panel reactive antibody greater than 20%, or flow cytometry crossmatch positivity) received 6 mg/kg. Results: There were no differences in patient or graft survival between the 3 groups. One-year rejection rates in the first 2 groups were 8.3% and 8.8%, respectively, comparable to contemporaneous rates reported to the Scientific Registry of Transplant Recipients. Dose tailoring permitted substantial cost savings estimated at US $1 091 502. Mean length of stay fell by almost 3 days as the protocol was refined. There were no episodes of phlebitis. Infection rates were comparable with those reported to the Scientific Registry of Transplant Recipients. Conclusions: The novel findings of the current study include peripheral administration, reduced dosing, favorable safety, excellent allograft outcomes, and clear associative data regarding reduced costs and length of stay. PMID- 29464205 TI - Pilot Study of Delayed ICOS/ICOS-L Blockade With alphaCD40 to Modulate Pathogenic Alloimmunity in a Primate Cardiac Allograft Model. AB - Background: Inducible costimulator (ICOS) is rapidly upregulated with T-cell stimulation and may represent an escape pathway for T-cell costimulation in the setting of CD40/CD154 costimulation blockade. Induction treatment exhibited no efficacy in a primate renal allograft model, but rodent transplant models suggest that the addition of delayed ICOS/ICOS-L blockade may prolong allograft survival and prevent chronic rejection. Here, we ask whether ICOS-Ig treatment, timed to anticipate ICOS upregulation, prolongs NHP cardiac allograft survival or attenuates pathogenic alloimmunity. Methods: Cynomolgus monkey heterotopic cardiac allograft recipients were treated with alphaCD40 (2C10R4, d0-90) either alone or with the addition of delayed ICOS-Ig (d63-110). Results: Median allograft survival was similar between ICOS-Ig + alphaCD40 (120 days, 120-125 days) and alphaCD40 (124 days, 89-178 days) treated animals, and delayed ICOS-Ig treatment did not prevent allograft rejection in animals with complete CD40 receptor coverage. Although CD4+ TEM cells were decreased in peripheral blood (115 +/- 24) and mLNs (49 +/- 1.9%) during ICOS-Ig treatment compared with monotherapy (214 +/- 27%, P = 0.01; 72 +/- 9.9%, P = 0.01, respectively), acute and chronic rejection scores and kinetics of alloAb elaboration were similar between groups. Conclusions: Delayed ICOS-Ig treatment with the reagent tested is probably ineffective in modulating pathogenic primate alloimmunity in this model. PMID- 29464206 TI - Improved Cuff Technique and Intraoperative Detection of Vascular Complications for Hind Limb Transplantation in Mice. AB - Background: Vascularized composite tissue allotransplantation (VCA) from a cadaveric donor has now become a clinical reality and the treatment modality of choice for patients with devastating injuries, deformities, and complex tissue defects. However, many VCA patients experience severe toxicities due to the strong immunosuppression required secondary to high antigenicity of the grafts. To improve immunosuppressive protocols for VCA, feasible and reliable preclinical models are necessary. The purpose of this study was to introduce new techniques to an established preclinical VCA model to accelerate future investigations. Methods: C57BL/6 (H-2b) and BALB/c (H-2d) mice were used to perform VCA as recipients and donors, respectively. Surgery time, success rate, associated complications, and mortality were analyzed. Blood flow in grafts was interrogated with laser speckle image (LSI). Results: A nonsuture cuff technique was used with the abdominal aorta for end-to-end anastomosis. The cuff technique demonstrated efficiency for donor surgery (52 +/- 10 minutes for donor vs. 45 +/- 8 minutes for recipient surgery). Successful revascularization was achieved in 27 (90%) of 30 transplants. The majority of surgical complications occurred within 48 hours including artery occlusion, venous occlusion, cerebral stroke, and minor bleeding without mortality. LSI was useful in detecting intraoperative vascular complications with display patterns predictive of complication type. Conclusions: The described techniques may facilitate a more efficient heterotopic hind limb transplantation mouse model of VCA. PMID- 29464207 TI - Socioeconomic Inequalities in the Kidney Transplantation Process: A Registry Based Study in Sweden. AB - Background: Few studies have examined the association between individual-level socioeconomic status and access to kidney transplantation. This study aims to investigate the association between predialysis income and education, and access to (i) the kidney waitlist (first listing), and (ii) kidney transplantation conditional on waitlist placement. Adjustment will be made for a number of medical and nonmedical factors. Methods: The Swedish Renal Register was linked to national registers for adult patients in Sweden who started dialysis during 1995 to 2013. We employed Cox proportional hazards models. Results: Nineteen per cent of patients were placed on the waitlist. Once on the waitlist, 80% received kidney transplantation. After adjusting for covariates, patients in the highest income quintile were found to have higher access to both the waitlist (hazard ratio [HR], 1.73; 95% confidence interval [CI], 1.53-1.96) and kidney transplantation (HR, 1.33; 95% CI, 1.16-1.53) compared with patients in the lowest income quintile. Patients with higher education also had better access to the waitlist and kidney transplantation (HR, 2.16; 95% CI, 1.94-2.40; and HR, 1.16; 95% CI, 1.03-1.30, respectively) compared with patients with mandatory education. Conclusions: Socioeconomic status-related inequalities exist with regard to both access to the waitlist, and kidney transplantation conditional on listing. However, the former inequality is substantially larger and is therefore expected to contribute more to societal inequalities. Further studies are needed to explore the potential mechanisms and strategies to reduce these inequalities. PMID- 29464208 TI - Multi-heme cytochromes provide a pathway for survival in energy-limited environments. AB - Bacterial reduction of oxidized sulfur species (OSS) is critical for energy production in anaerobic marine subsurfaces. In organic-poor sediments, H2 has been considered as a major energy source for bacterial respiration. We identified outer-membrane cytochromes (OMCs) that are broadly conserved in sediment OSS respiring bacteria and enable cells to directly use electrons from insoluble minerals via extracellular electron transport. Biochemical, transcriptomic, and microscopic analyses revealed that the identified OMCs were highly expressed on the surface of cells and nanofilaments in response to electron donor limitation. This electron uptake mechanism provides sufficient but minimum energy to drive the reduction of sulfate and other OSS. These results suggest a widespread mechanism for survival of OSS-respiring bacteria via electron uptake from solid minerals in energy-poor marine sediments. PMID- 29464209 TI - Survival of spin state in magnetic porphyrins contacted by graphene nanoribbons. AB - We report on the construction and magnetic characterization of a fully functional hybrid molecular system composed of a single magnetic porphyrin molecule bonded to graphene nanoribbons with atomically precise contacts. We use on-surface synthesis to direct the hybrid creation by combining two molecular precursors on a gold surface. High-resolution imaging with a scanning tunneling microscope finds that the porphyrin core fuses into the graphene nanoribbons through the formation of new carbon rings at chemically predefined positions. These ensure the stability of the hybrid and the extension of the conjugated character of the ribbon into the molecule. By means of inelastic tunneling spectroscopy, we prove the survival of the magnetic functionality of the contacted porphyrin. The molecular spin appears unaffected by the graphenoid electrodes, and we simply observe that the magnetic anisotropy appears modified depending on the precise structure of the contacts. PMID- 29464210 TI - Topological transport of sound mediated by spin-redirection geometric phase. AB - When a dynamic system undergoes a cyclic evolution, a geometric phase that depends only on the path traversed in parameter space can arise in addition to the normal dynamical phase. These geometric phases have profound impacts in both quantum and classical physics. In addition to the geometric phase associated with band structures in reciprocal space that has led to the discovery of topological insulators, the spin-redirection geometric phase induced by the SO(3) rotation of states in real space can also give rise to intriguing phenomena such as the photonic analog of the spin Hall effect. By exploiting the orbital angular momentum of sound vortices, we theoretically and experimentally demonstrate the spin-redirection geometric phase effects in airborne sound, which is a scalar wave without spin. We show that these effects, associated with the helical transport of sound, can be used to control the flow of sound. This finding opens new possibilities for the manipulation of scalar wave propagation by exploiting spin-redirection geometric phases. PMID- 29464211 TI - Probing quantum coherence in single-atom electron spin resonance. AB - Spin resonance of individual spin centers allows applications ranging from quantum information technology to atomic-scale magnetometry. To protect the quantum properties of a spin, control over its local environment, including energy relaxation and decoherence processes, is crucial. However, in most existing architectures, the environment remains fixed by the crystal structure and electrical contacts. Recently, spin-polarized scanning tunneling microscopy (STM), in combination with electron spin resonance (ESR), allowed the study of single adatoms and inter-atomic coupling with an unprecedented combination of spatial and energy resolution. We elucidate and control the interplay of an Fe single spin with its atomic-scale environment by precisely tuning the phase coherence time T2 using the STM tip as a variable electrode. We find that the decoherence rate is the sum of two main contributions. The first scales linearly with tunnel current and shows that, on average, every tunneling electron causes one dephasing event. The second, effective even without current, arises from thermally activated spin-flip processes of tip spins. Understanding these interactions allows us to maximize T2 and improve the energy resolution. It also allows us to maximize the amplitude of the ESR signal, which supports measurements even at elevated temperatures as high as 4 K. Thus, ESR-STM allows control of quantum coherence in individual, electrically accessible spins. PMID- 29464212 TI - Understanding the informational needs of patients with IPF and their caregivers: 'You get diagnosed, and you ask this question right away, what does this mean?' AB - Background: Idiopathic pulmonary fibrosis (IPF) is a progressive, incurable lung disease whose intrusive symptoms rob patients of their quality of life. Patients with IPF rely on their caregivers for support and assistance in amounts that vary according to patients' individual circumstances and disease severity. Knowledgeable and well-informed patients and caregivers are best suited to deal with life-altering conditions like IPF. Methods: We conducted two hour-long focus groups with 13 patients with IPF and 4 caregivers of patients with IPF to better understand their informational needs and in what format such information should be delivered. Results: Patients discussed the challenges IPF creates in their daily lives. They wanted information on how to live well despite having IPF, practical information on how they could remain active and travel and how they could preserve their quality of life despite living with a life-threatening disease like IPF. Caregivers wanted information on the general aspects of IPF, because it would help them understand what patients were going through. They also wanted specific information on how to give care to a patient with IPF, even when physical care may not be needed (as in earlier phases of the disease). Patients and caregivers both needed efficient information delivery from trustworthy sources, including the healthcare team involved in their care. They considered both spoken and written information valuable, and ease of access was critical. Conclusion: This study provides valuable insight regarding the informational needs of IPF patients and their caregivers. It is hoped that identifying or creating sources of this information, and insuring that patients and caregivers have access to it, will improve well-being for patients with IPF and their caregivers. PMID- 29464213 TI - Effect of initial lactate level on short-term survival in patients with out-of hospital cardiac arrest. AB - Purpose: This study evaluated whether serum lactate levels (SLL) at admission in patients with cardiac arrest (CA) can predict successful return of spontaneous circulation (ROSC) or short-term survival, especially within the first 24 h. Materials and methods: This prospective, observational study was conducted in the emergency department (ED) of a training and research hospital from April 2015 through February 2016. It included all patients older than 18 years who presented to the ED during the study period with non-traumatic out-of-hospital cardiac arrest (OHCA). The study measured two outcomes: whether ROSC was achieved and whether short-term survival was achieved. ROSC was defined as the presence of spontaneous circulation for the first hour after cardiopulmonary resuscitation (CPR). Survival was defined as having survived for a minimum of 24 h after ROSC. Results: The study included 140 patients who were admitted to the ED with OHCA. ROSC was achieved in 55 patients (39.3%), and survival for 24 h following CA was achieved in 42 patients (30%). The mean SLL in the ROSC (+) and ROSC (-) groups were 9.1 +/- 3.2 mmol/L and 9.8 +/- 2.9 mmol/L, respectively. The mean SLL in the survivor and non-survivor groups were 8.6 +/- 2.9 mmol/L and 10 +/- 3.1 mmol/L, respectively. These differences were not statistically significant (p = 0.1). A multivariate regression model assessing the factors that predicted both ROSC and 24-h survival showed the odds ratio (OR) of initial SLL was 1.3 (95% CI: 1.05 1.6) and 1.1 (95% CI: 0.9-1.3), respectively. Conclusions: This study showed that in OHCA patients, SLL on admission was not associated with increased ROSC achievement or 24-h survival. PMID- 29464214 TI - The diagnostic value of complete blood count parameters in patients with subarachnoid hemorrhage. AB - Objectives: Diagnosis of subarachnoid hemorrhage (SAH) in patients presenting with headache is challenging and there has been any biomarker studied for excluding of SAH in those patients. We aim to determine the sensitivity of leukocytosis or left shift to exclude the diagnosis of SAH in ED patients presenting with headache. Method: Adult patients with headache who received a computed tomography (CT) with the diagnosis of SAH and had a complete blood count (CBC) represent the case group, headache patients with normal CT and had a CBC represent the control group. The white blood cell (WBC) count and percentage of polymorphonuclear cells (PMNs%) taken during admission and within the first 6 and 12 h of admission were recorded. Results: A hundred ninety seven patients with SAH and 197 patients without SAH were enrolled in to study. Sensitivity, specificity, NPV and PPV of leukocytosis or increase in PMNs% (left shift) in the diagnosis of SAH was 89.8% (84.5-93.5, 95% CI), 46.7% (39.6-53.9, 95% CI), 82.1% (73.5-88.4, 95% CI) and 62.8% (56.8-68.4, 95% CI) respectively on initial emergency department (ED) admission. Conclusion: CBC should be considered as a noninvasive test for the exclusion of SAH in ED patients with 6 h observation. PMID- 29464215 TI - Accuracy of point-of-care ultrasound using low frequency curvilinear transducer in the diagnosis of shoulder dislocation and confirmation of appropriate reduction. AB - Background: Ultrasound (US) is an effective modality in the evaluation of shoulder dislocation and reduction. In most studies, high frequency US probes have been used. Objective: To determine the sensitivity and specificity of low frequency US in the diagnosis of shoulder dislocation and its proper reduction in the emergency department (ED). Methods: In a prospective observational study 84 patients, suspicious of shoulder dislocation, were enrolled in our study. In ED, they all underwent low frequency (curve) probe US examination by the emergency physician at the time of admission. Standard radiographies of their shoulder joints were taken later and then reported by the attending radiologist. As soon as the shoulder dislocation was confirmed, reduction of the joint was done under procedural sedation and analgesia. US and radiography of the relocated joint were taken for the second time. The sensitivity and specificity of low frequency US were compared with radiography by the appropriate statistical analysis. Results: In comparison to radiography, US had a sensitivity of 100.0%, specificity of 80.0%, positive predictive value of 98.7%, and negative predictive value of 100.0% in diagnosis of shoulder dislocation. The specificity of US in diagnosis of proper reduction of the joint, was estimated to be 98.7% with a negative predictive value of 100.0%. US took a significantly less time than radiography to be performed (p < 0.001). Conclusions: Low frequency US is highly accurate in diagnosing shoulder dislocation and its proper reduction. Thus it might be a good substitute for radiography in these situations. PMID- 29464216 TI - Demographic and clinical characteristics among Turkish homeless patients presenting to the emergency department. AB - Objective: Since the homeless are at greater risk of encountering health problems than the general population, the reasons for and incidence of their presentations to emergency departments also vary. The purpose of this study was to determine the sociodemographic and clinical characteristics of Turkish homeless patients who brought to the emergency department by ambulance. Materials and methods: The records of homeless adult patients brought to the ED by 112 emergency service ambulance teams over a 1-year period from January to December, 2014, were examined retrospectively. Results: Thirty-six (21.56%) of the homeless patients enrolled in the study presented due to trauma, and 131 (78.44%) due to non traumatic causes. One hundred thirty-seven (82.04%) of the total patient group were male. The mean age of the non-trauma patients was 47.3 +/- 15.2 years (range, 18-81 years), and the mean age of the trauma patients was 36.9 +/- 14.4 years (range, 18-63 years). The most common reason for presentation among patients presenting to the emergency department for non-trauma reasons was clouded consciousness (n = 39, 23.35%), followed by general impaired condition (n = 26, 15.57%), respiratory difficulty (n = 25 14.97%) and abdominal pain (n = 21, 12.57%). The most common reason for presentation among trauma cases was traffic accidents (n = 13, 7.78%), followed by sharp implement injury (n = 9, 5.39%). Four (2.4%) homeless patients died in the emergency department, three (%1.8) homeless patients discharged from the emergency department, and the remaining 160 (95.8%) were admitted to the hospital. Conclusion: Homeless patients may present to the emergency department due to traumatic or non-traumatic causes. Admission levels are high among these patients, who may have many acute and chronic problems, and appropriate precautions must be taken in the management of these subjects in the emergency department. PMID- 29464218 TI - A ventricular septal defect restricted by the tricuspid septal leaflet and discrete subaortic membrane presenting with high-grade atrioventricular block and syncope. PMID- 29464217 TI - A retrospective analysis of cases with neuroleptic malignant syndrome and an evaluation of risk factors for mortality. AB - Objective: Neuroleptic malignant syndrome (NMS) is a neurological emergency rarely encountered in clinical practice but with a high mortality rate. Cases associated with atypical antipsychotic use or termination of dopamine agonists have been seen in recent years. The purpose of this study was to assess the presence of risk factors for mortality by investigating all clinical and laboratory characteristics of cases with NMS. Material and methods: This descriptive, cross-sectional study retrospectively investigated all clinical and laboratory characteristics by scanning the ICD-10 codes of patients presenting to the XXXX Faculty of Medicine Emergency Department and diagnosed with NMS between 2006 and 2016. Patients were divided into surviving and non-surviving groups, and the data elicited were subjected to statistical comparisons. Results: The mean age of the 18 patients diagnosed with NMS was 46.9 +/- 4.8 years, and 50% were women. In addition to antipsychotics among the drugs leading to NMS, the syndrome also developed as a result of levodopa withdrawal in three patients and metoclopramide use in one patient. Statistically significant differences were determined between the surviving and non-surviving patients in terms of blood pressure, blood urea nitrogen (BUN), creatine kinase (CK) and mean platelet volume (MPV) values (p <= 0.05). Conclusion: In this study the most common agent that cause NMS was atypical antipsychotics. Also advanced age, increased blood pressure and serum CK, BUN and MPV values were identified as potential risk factors for mortality in NMS. PMID- 29464219 TI - Typical pericarditis ECG findings after falling from height. The PR segment depression or ST segment elevation? AB - Acute pericarditis (AP) following blunt thoracic trauma is rare and difficult to diagnosis. A 43-year-old man with offered to the emergency department (ED) after falling from height before a week ago. The ECG performed in the ED was abnormal, ECG revealed PR segment depression in leads DII, DIII, aVF, and V3-6 and a preliminary diagnosis of acute inferolateral STEMI was presumed. Patients have evidence of systemic inflammation, including leukocytosis, elevated erythrocyte sedimentation rate. We are reporting a case of post-traumatic acute pericarditis presenting with PR-segment depression and normal cardiac enzymes mimicking acute STEMI. PMID- 29464220 TI - A rare cause of acute abdomen in the ED: Chemotherapy-induced pneumatosis intestinalis. AB - Pneumatosis intestinalis (PI) and portomesenteric venous gas (PVG) refers to the presence of air within the intestinal wall and portomesenteric vessels. Most of the time, it is associated with mesenteric ischemia that requires immediate surgical intervention as it has high mortality rate. It may also be seen secondary to various conditions, including infections, surgeries, and some chemotherapeutic drugs. A 61-year old-male was admitted to our emergency department complaining of abdominal pain after chemotherapy. Radiological evaluation of the patient demonstrated massive PVG and PI. Patient underwent urgent surgery due to the possibility of intestinal ischemia and infarction, but no necrosis was identified Chemotherapeutic drug-induced PI and PVG was the final diagnosis. Although PI and PVG are signs of mesenteric ischemia and intestinal necrosis most the of time, chemotherapeutic drugs may also cause PI and PVG rarely. Recent history of chemotheraphy and absence of any mesenteric vascular occlusion may be the diagnostic clue. PMID- 29464221 TI - A young puerperal woman presenting to emergency department with severe dyspnea. AB - Peripartum cardiomyopathy (PPCM) is an idiopathic cardiomyopathy presenting with heart failure (HF) secondary to left ventricular systolic dysfunction towards the end of pregnancy or in the months following delivery, where no other cause of HF is found. The symptoms and signs of this rare disorder mimic those of the physiological changes of pregnancy or other cardiovascular diseases. Consequently, its diagnosis is frequently delayed, which worsens an already poor prognosis. Here, we report a young adult who was diagnosed with PPCM, early, with the help of focused cardiac ultrasonography, performed after presenting to the emergency department with nonspecific respiratory complaints, including dyspnea and hemoptysis, which suggested at first pulmonary embolism. PMID- 29464222 TI - Nivolumab, a new immunomodulatory drug, a new adverse effect; adrenal crisis. AB - Owing to the advancements in medicine, new information is obtained regarding cancer, new antineoplastic agents are developed. Frequent use of these new pharmacological agents emergency physicians to be vigilant about their side effects. We present a case of adrenal crisis in a patient with non-small cell lung cancer (NSCLC), caused by an immunomodulatory drug; nivolumab. While adverse events are related to other immunomodulatory drugs have been reported in literature, our case is the first nivolumab-related adrenal failure to be reported. A patient with lung cancer presented to the emergency room(ER) with nausea and vomiting. Hyponatremia, hyperkalemia, persistent hypoglycemia led to the diagnosis of adrenal crisis. Having direct effect on the immune system, these drugs were claimed to be highly reliable. However, there is no reliable data on the side effect profile of these agents. It should be kept in mind that life threatening auto-immune reactions may occur. PMID- 29464224 TI - Acne in adolescents. AB - BACKGROUND: Acne vulgaris affects more than 90% of Australian adolescents aged 16 18 years. It may have a significantly deleterious effect on their self-esteem and emotional state. Moderate-to-severe acne can lead to scarring. There are many treatment options available. Most teenagers obtain information from their peers or from the internet. OBJECTIVE: The aim of this article is to inform general practitioners (GPs) of the pathogenesis, physiology and description of acne, as well as therapeutic options, including topical and systemic therapies. Skin care, diet and other factors of importance are also discussed. DISCUSSION: The first point of contact with patients is in general practice. GPs effectively manage most patients with acne. Treatment choice is guided by experience, with many clinical acne treatment guidelines available. The most common reason for treatment failure is insufficient duration of therapy. Successful treatments require months of topical agents and, in many cases, additional systemic therapies. Internationally, there is a resurgence in the basic research of acne vulgaris, leading to new topical and systemic treatments. PMID- 29464223 TI - Determinants of inappropriate acute pain management in old people unable to communicate verbally in the emergency department. AB - Objectives: Poor pain management is relevant among individuals unable to communicate verbally (UCV). Analgesia may be due to three determinants: patients' status, physician's characteristics and pain etiology. Our aim is to investigate the association between prescription of ED pain treatment and these determinants. Materials and Methods: An observational prospective study including UCV patients was conducted. Severity of pain was evaluated by ALGOPLUS Scale and a score P >= 2 out of 5 on the pain scale was retained as the threshold for the presence of acute pain in elderly UCV patients. Results: Our data showed that only 31,9% of UCV patients received a pharmacological treatment. The presence of the caregiver would influence the rate of therapy administration [OR 6,19 (95% CI 2,6-14,75)]. The presence of leg pain [OR 0,32 (95% CI 0,12-0,86)] and head pain [OR 0,29 (95% CI 0,10-0,84)] were less likely associated to receive analgesia. Pain related to trauma [OR 4.82 (95% CI 1.17 to 19.78)] and youngest physicians [OR 1.08 (95% CI 1.001 to 1.18)] were variables associated with the administration of drugs opiates. Discussion: Older UCV patients presenting to the ED with pain are at high risk of inadequate analgesia. Providers should always suspect presence of pain and an increasing need for behavioural pain evaluation is necessary for a complete assessment. Conclusions: Presence of a caregiver influences a more appropriate pain management in these patients. Staff training on pain management could result in better assessment, treatment, and interaction with caregivers. PMID- 29464225 TI - Eczema management in school-aged children. AB - BACKGROUND: Atopic eczema is a relapsing inflammatory skin condition that can be lifelong. Management of eczema is often focused on infants, with many school-aged children undertreated. Uncontrolled eczema has a significant impact on the quality of life of the child and their family. OBJECTIVE: The objective of this article is to discuss the practical management of eczema in school-aged children. DISCUSSION: This article will describe how eczema manifests in school-aged children, focusing on when to suspect triggers and how to manage these from a general practice perspective, and when to refer the child on to specialist services. PMID- 29464226 TI - Depression in children. AB - BACKGROUND: Major depressive disorder (MDD) in children (5-12 years of age) is a confronting and serious psychiatric illness. MDD has significant ramifications for the psychosocial development of the child, yet it remains under-recognised and undertreated. General practice is where these children and their parents will first present. OBJECTIVE: The aim of this article is to provide general practitioners (GPs) with a framework for considering MDD in a child and recommendations for treatment. DISCUSSION: Children with MDD have the same core features as adolescents and adults, taking into account the child's capacities for cognition and language, and developmental stage. Earlier onset of illness is associated with poorer outcomes and greater psychiatric morbidity persisting into adulthood. MDD is more common than anticipated, and should be considered for any child presenting with depressive symptoms and/or impaired psychosocial functioning. Despite limited evidence, numerous interventions exist that will, ideally, significantly affect the child's developmental trajectory. GPs are in an important position to initiate these interventions. PMID- 29464227 TI - Childhood constipation. AB - BACKGROUND: Constipation is best defined as difficulty passing stools that may be infrequent (<=2 per week), painful and associated with stool retention. Childhood constipation is common, with a prevalence of 3-30% worldwide. Most constipation in children is functional and related to behavioural withholding after an unpleasant stool event. Successful diagnosis and management can occur in primary care, and specialist referral is only needed for refractory cases or concerns regarding organic pathology. OBJECTIVE: This article aims to provide a structure for evaluating, diagnosing and managing childhood functional constipation in general practice. DISCUSSION: Structured history and examination can screen for organic pathology or red flags that require specialist referral. Investigations such as abdominal X-ray are not routine. Early management of childhood constipation provides improved quality of life for patients and their families. Management, including disimpaction and maintenance, should maintain continuity of care and provide long-term support for families. PMID- 29464228 TI - Growth disorders in adolescents. AB - BACKGROUND: Growth is one of the fundamental processes of adolescent development. Careful history and examination, and relevant tar-geted investigations, can streamline the referral process, highlighting the important role of primary healthcare clinicians. OBJECTIVE: This article will provide a guide for clinicians to categorise growth patterns in adolescents, and recognise patients who may have a growth disorder. It will assist clinicians in considering appropriate investigations, and provide guidance for when to refer the adolescent to appropriate paediatric specialists. DISCUSSION: Causes of tall and short stature can often be distinguished on history, physical examination, and accurate pubertal staging. The height of the adolescent should always be considered in the context of their genetic potential. Physiological variants re-main the most common reason for short stature, but awareness of the features of pathological causes is critical. One of the most common presentations is maturational delay in males, and an approach to this issue is discussed. PMID- 29464229 TI - Management of bariatric patients beyond the scalpel. AB - BACKGROUND: Obesity management in general practice sometimes involves referral of patients for bariatric surgery. Integral to the success of long-term weight loss maintenance is supporting the patient's psychological, nutritional and exercise needs. OBJECTIVE: This article is written to equip general practitioners (GPs) to manage the comprehensive needs, before and after bariatric surgery, of patients who are obese. DISCUSSION: The number of patients undergoing bariatric surgery in Australia has increased significantly in the past few years. Pre-operative and postoperative management of this intervention presents a challenge for GPs. In this article we provide guidance around psychological, nutritional and exercise interventions, to equip GPs in managing patients who are obese. Access to allied health providers is not always available for patients, so this article is co written with allied health colleagues who share their expertise as a resource for GPs. PMID- 29464230 TI - The Australian Mid-West Coastal Marine Wound Infections Study. AB - BACKGROUND: Marine organism wound infections are common in coastal regions of Western Australia. Local treatment guidelines are based on studies from elsewhere. The objective of this article was to identify the causative organisms in marine wounds sustained in the subtropical and tropical coastal waters of the Indian Ocean, Gascoyne region (north-west), Western Australia. METHODS: This was a prospective study. A single wound swab was taken from 28 consenting patients who presented with a suppurating marine wound to the emergency departments of Carnarvon and Exmouth hospitals. RESULTS: The wounds of 27 out of 28 patients returned a positive culture. The two most common organisms were Staphylococcus aureus (n = 18/28; 64.3%) and Vibrio species (n = 9/28; 32.1%). The culture was polymicrobial in 11 patients (39.3%). DISCUSSION: S. aureus or Vibrio species were frequently seen in marine wounds, and infections were often polymicrobial. Our results suggest that flucloxacillin (or clindamycin) and doxycycline (or ciprofloxacin) would be a reasonable combination for empirical oral therapy in adults. PMID- 29464231 TI - A mixed-methods feasibility study of routinely weighing patients in general practice to aid weight management. AB - BACKGROUND: The optimal role of general practice in population weight management remains unclear. The aim of this mixed-methods study was to test the feasibility of routinely weighing all adult patients attending their general practice as an intervention to aid weight management in clinical practice. METHODS: Consenting patients in six general practices were weighed at each presentation over a 12 month period. Data were analysed using linear mixed growth models. Participants' interviews at the completion of the study were thematically analysed. RESULTS: The overall weight loss in patients who completed the study (n = 217) was 0.51 kg (P = 0.26; not significant); in patients who were obese (n = 106) there was a greater weight loss of 1.79 kg (P = 0.04). Patients were receptive to the intervention; however, there was disruption to clinical workflow. DISCUSSION: Routinely weighing adult patients in general practice is feasible, requires resources and may be associated with weight loss in patients who are obese. Further research is required to inform support for implementation within practices. PMID- 29464232 TI - Psychological distress and risky sexual behaviours among women aged 16-25 years in Victoria, Australia. AB - BACKGROUND: Identifying factors related to risky sexual behaviour may contribute to preventive and interventional approaches to reduce negative mental health outcomes among young women. The aim of this study was to investigate the association between psychological distress and risky sexual behaviours in females aged 16-25 years in Victoria, Australia. METHODS: Data were extracted from the Young Female Health Initiative (YFHI), a study in which participants were recruited via advertisements on Facebook. Logistic regression was used to assess associations between psychological distress, as measured by the Kessler 10 (K10) Psychological Distress Scale, and risky sexual behaviours. RESULTS: Data were available from 200 sexually active participants and 40 non-sexually active participants. We found that the K10 score was independently associated with sex while under the influence of alcohol or drugs (odds ratio: 1.7; 95% confidence intervals: 1.2, 2.7; P = 0.006). DISCUSSION: Although data were collected from a small sample of young women, we found that those with underlying psychological distress may adopt risky sexual behaviours, especially if concomitantly drinking alcohol or taking drugs. PMID- 29464233 TI - Understanding the decision to commence a dose administration aid. AB - BACKGROUND: The use of dose administration aids (DAAs), such as compartmentalised boxes (eg dosette) or medicine packs (eg Webster-pak), is common, particularly among patients with chronic disease. The aim of this study was to investigate factors influencing patients' decisions to commence using a DAA with a view to summarising implications for practice for general practitioners (GPs). METHODS: Semi-structured interviews were undertaken with participants living in a regional town in South Australia. Analysis of transcripts was facilitated using a qualitative analysis grid. RESULTS: Eight participants were interviewed. Four main themes included complexity of managing medications, DAAs as a cultural artefact, taking the lead in decision making, and weight of influence of health professionals. DISCUSSION: This study highlights the role of individual autonomy, close relatives and pharmacy staff in decisions to commence using a DAA. Tablets included in DAAs can take priority over inhaled and injected medications. GPs have an important role in ensuring that commencing a DAA helps empower patients to improve their healthcare management and does not inhibit communication between patient, doctor and pharmacist. PMID- 29464234 TI - You should get that mole checked out: Ethical and legal considerations of the unsolicited clinical opinion. AB - BACKGROUND: Legal and ethical obligations do not always align when doctors become aware of a clinical situation involving a person with whom they have no pre existing therapeutic relationship. Noting a potentially malignant skin lesion, such as a melanoma on a person outside the clinical setting, provides a pertinent example. OBJECTIVE: The aim of this article is to describe the legal, ethical and professional considerations surrounding proffering a dermatological opinion in the case of suspected melanoma outside the clinical setting. DISCUSSION: The application of professional and ethical standards may require the doctor to act in some way to alert the person of their findings in a context whereby there is no defined positive duty to do so in Australian law. The degree to which the doctor is ethically obligated to provide an unsolicited dermatological opinion is affected by numerous and, oftentimes, competing factors. PMID- 29464236 TI - AFP reviewers 2017. PMID- 29464235 TI - Occupational violence and staff safety in general practice. AB - BACKGROUND: The recent death of a Victorian surgeon who was assaulted by a member of the public when leaving work has re-highlighted the risk and potential cost of violence experienced by healthcare workers. OBJECTIVE: The aim of this article is to outline the risk of occupational violence experienced by doctors, and general practitioners in particular, and to discuss practical measures that can be taken to manage this risk. DISCUSSION: The majority of doctors have experienced aggression or violence in their workplaces in the past 12 months. Risks for violence include elements of workplace design, policy and procedures, and client factors. A series of practical tools designed to assist the assessment and management of risk of occupational violence are discussed. PMID- 29464237 TI - Magneto-structural correlations in oxalate-bridged Sr(ii)Cr(iii) coordination polymers: structure, magnetization, X-band, and high-field ESR studies. AB - The results of high-field electron spin resonance (HF-ESR) spectroscopy on the title 1D coordination polymers at frequencies up to 415 GHz, supported by X-ray diffraction, thermal, magnetic susceptibility, and X-band (10 GHz) ESR studies, are presented. The heterometallic compounds {SrCr2(phen)2(C2O4)4}.H2O (SrCrPhen) and {SrCr2(bpy)2(C2O4)4(H2O)}.5H2O (SrCrBpy) (phen = 1,10-phenanthroline, bpy = 2,2'-bipyridine) were synthesized. Structural analysis revealed double oxalate bridged zigzag Sr-Cr chains while magnetic susceptibility studies showed paramagnetic behaviour of the complexes. HF-ESR spectroscopy data were analysed with a relevant spin-Hamiltonian, yielding the g, D and E parameters of the Cr(iii) ions. Both complexes showed small magnetic easy-axis type anisotropy with |D| ~ 1 K; SrCrBpy has uniaxial anisotropy while SrCrPhen has biaxial anisotropy. HF-ESR studies have enabled us to establish rational magneto-structural correlations and revealed significant differences between very similar crystal structures. Additionally, the ability of SrCrPhen and SrCrBpy to be single-source precursors for the formation of Sr-Cr oxides was investigated. PMID- 29464238 TI - A fluorescent microporous crystalline dendrimer discriminates vapour molecules. AB - A self-assembled crystalline microporous dendrimer framework (MDF) exhibits novel turn-on and ratiometric fluorescence upon exposure to solvent vapours. The donor acceptor character, combined with the large surface area (>650 m2 g-1), allows the MDF to discriminate vapours of volatile solvents with turn-on and colour change of photoluminescence. PMID- 29464239 TI - Effect of stacking order and in-plane strain on the electronic properties of bilayer GeSe. AB - Germanium selenide as a new layered material is promising for nanoelectronic applications due to its unique optoelectronic properties and tunable band gap. In this study, based on density functional theory, we systematically investigated the structure, stability, and electronic properties of bilayer germanium selenide with four different stacking orders (namely AA-, AB-, AC- and AD-stacking). The obtained results indicated that the band gap is dependent on the stacking order with an indirect band gap for AA- and AC-stacking and direct band gap for AB- and AD-stacking. In addition, we also found that the band gap of the GeSe bilayer with different stacking orders can be tuned by in-plane strain. The transition between the direct to indirect band gap or semiconductor to metal is tunable. In particular, the direct band gap of the AB-stacking germanium selenide bilayer can be tuned in a wide energy range under applied strain along the armchair direction. PMID- 29464240 TI - Gellan Gum-based luminal fillers for peripheral nerve regeneration: an in vivo study in the rat sciatic nerve repair model. AB - Peripheral nerve injuries (PNI) resulting in a gap to be bridged between the transected nerve ends are commonly reconstructed with autologous nerve tissue, but there is a need for valuable alternatives. This experimental work considers the innovative use of the biomaterial Gellan Gum (GG) as a luminal filler for nerve guidance channels made from chitosan with a 5% degree of acetylation. The engineered constructs should remodel the structural support given to regenerating axons by the so-called bands of Bungner. Four different GG formulations were produced by combining varying amounts of High-Acyl GG (HA-GG) and Methacrylated GG (MA-GG). The effective porosity of the freeze-dried networks was analysed by SEM and micro-CT 3D reconstructions, while the degradation and swelling abilities were characterized in vitro for up to 30 days. The metabolic activity and viability of immortalized Schwann cells seeded onto the freeze-dried networks were also evaluated. Finally, the developed hydrogel formulations were freeze dried within the chitosan nerve guides and implanted in a 10 mm rat sciatic nerve defect. Functional and histomorphological analyses after 3, 6, and 12 weeks in vivo revealed that although it did not result in improved nerve regeneration, the NGC25:75 formulations could provide a basis for further development of GG scaffolds as luminal fillers for hollow nerve guidance channels. PMID- 29464241 TI - Gas-stimuli-responsive molecularly imprinted polymer particles with switchable affinity for target protein. AB - Gas-responsive molecularly imprinted polymer (MIP) particles, which have nanocavities in their shell layer for protein recognition, were developed for the first time. The MIP particles showed higher affinity for the target protein inside a CO2-treated aqueous medium as compared to that under N2-treated conditions, while retaining selectivity to the target protein. PMID- 29464242 TI - Dynamical heterogeneities in ionic liquids as revealed from deuteron NMR. AB - The heterogeneity in dynamics has important consequences for understanding the viscosity, diffusion, ionic mobility, and the rates of chemical reactions in technology relevant systems such as polymers, metallic glasses, aqueous solutions, and inorganic materials. Herein, we study the spatial and dynamic heterogeneities in ionic liquids by means of solid state NMR spectroscopy. In the 2H spectra of the protic ionic liquid [TEA][OTf] we observe anisotropic and isotropic signals at the same time. The spectra measured below the melting temperature at 306 K could be simulated by a superposition of the solid and liquid line shapes, which provided the transition enthalpies between the rigid and mobile fractions. Consequently, we measured the spin-lattice relaxation times T1 for the anisotropic and the isotropic signals for the temperature range between 203 and 436 K. Both dispersion curves could be fitted to models including rotational correlation times, activation barriers and rate constants. This approach allowed determining the rotational correlation times for the N-D molecular vector of the [TEA]+ cation in differently mobile environments. The mobility is only slightly different, as indicated by small differences in activation energies for these processes. The NMR correlation times for the highly mobile phase are linearly related to measured viscosities, which supports the applicability of the Stokes-Einstein-Debye relation. PMID- 29464243 TI - Sensitive detection of intracellular microRNA based on a flowerlike vector with catalytic hairpin assembly.

PMID- 29464244 TI - Investigation of magneto-structural correlation based on a series of seven coordinated beta-diketone Dy(iii) single-ion magnets with C2v and C3v local symmetry. AB - A series of four beta-diketone mononuclear Dy(iii) complexes, namely Dy(Hthd)3(MeOH).2,5-Py (1), Dy(Hthd)3(Tppo) (2), Dy(Hthd)3(PyNO) (3), and Dy(Hthd)3(4-PyNO) (4) (Hthd = 2,2,6,6-tetramethyl-3,5-heptanedione, 2,5-Py = 2,5 pyridine, Tppo = triphenylphosphine oxide, PyNO = pyridine N-oxide, 4-PyNO = 4 methylpyridine N-oxide), have been isolated by reactions of Hthd, DyCl3.6H2O and an auxiliary ligand. X-ray crystallographic analysis revealed that complexes 1-4 are all seven-coordinated mononuclear structures with C2v or C3v local symmetry. The magnetic measurements of complexes 1-4 revealed their field-induced single ion magnet (SIM) behavior, due to mixed low-lying states. The crystal field parameters and orientations of the magnetic easy axes were obtained from simulations of the DC magnetic data and an electrostatic model calculation. The magneto-structural correlation of seven-coordinated Dy(iii) SIMs with low symmetry coordination environments was further discussed.

AB - We report on the friction and diffusion of a single mobile nano-colloidal disk, whose size and mass are one and two orders of magnitude, respectively, greater than the molecules of the host solvent; all particles are restricted to move in a two-dimensional space. Using molecular dynamics simulations, the variation of the transport coefficients as a function of the thermodynamic state of the supporting fluid, in particular, around those states in the neighbourhood of the liquid liquid phase coexistence, is investigated. The diffusion coefficient is determined through the fit of the mean-square displacement at long times and with the Green-Kubo relationship for the velocity autocorrelation function, whereas the friction coefficient is computed from the correlation of the fluctuating force. From the determination of the transport properties, the applicability of the Stokes-Einstein relation in two dimensions around the second critical point is discussed.

AB - Hydride transfer promoted by the coordination of a substrate molecule to a Lewis acid is a critical step in many catalytic transformations. This computational study investigates the nature of the interaction between a polar substrate molecule and a Lewis acid by examining the influence of Lewis acid strength on the ability to reduce (transfer a hydride to) the coordinated substrate molecule. To investigate this interaction, the coordination of 10 probe substrates to seven Lewis acids was analyzed. Coordination of the probe substrate molecules to a Lewis acid resulted in a more favorable reduction of the substrate molecule by 20 70 kcal mol-1. Further examination of the coordination of the substrate molecules to Lewis acids of varying Lewis acid strengths resulted in a direct linear correlation between the ability of the Lewis acid-substrate adduct to accept a hydride and the Lewis acid strength. The linear correlations also revealed that between 44 and 70% of the Lewis acidity of the Lewis acids translated to the Lewis acid-substrate adducts. From the results obtained in this study, the minimum Lewis acid strength needed to activate the substrates for the reduction with [BH4]- and the implications of employing a Lewis acid to promote the reduction of an unsaturated polar substrate in catalytic reactions are also described.

AB - Acceptor-doped barium zirconates are currently receiving considerable interest because of their high proton conductivity at intermediate temperatures, making them applicable as electrolytes in various electrochemical devices, but the mechanism of proton conduction is unclear. Here, we investigate the role of the acceptor-dopant level in the localized proton motions, i.e. proton transfers between oxygens and O-H reorientations, in hydrated samples of the proton conducting, acceptor-doped, perovskites BaZr1-xInxO3-x/2 with x = 0.10 and 0.20, using quasielastic neutron scattering (QENS). Analysis of the QENS spectra reveals that several proton transfer and O-H reorientational motions contribute to the QENS signal, as a consequence of the locally disordered nature of the structure due to the In doping of these materials, and establishes a generic and complex picture of localized proton dynamics in acceptor-doped barium zirconate based proton conductors. A comparison of the QENS results with vibrational spectroscopy data of the same materials, as reported in the literature, suggests a predominance of O-H reorientational motions in the observed dynamics. The highest doping level corresponds to a more distorted structure and faster dynamics, which thus indicates that some degree of structural disorder is favourable for high local proton mobility.

AB - Programmable surface-patterned functional DNA density is achieved via manipulation of molecular-level defects through chemical lift-off lithography. Artificial SAM defects are well-tunable by a contact-induced reaction, enabling molecular environment guidance and DNA insertion to be spatially and quantitatively addressable. This straightforward molecular density control creates an advanced avenue toward fabricating multiplexed bioactive substrates. PMID- 29464250 TI - Ce-Doped bundled ultrafine diameter tungsten oxide nanowires with enhanced electrochromic performance. AB - Cerium (Ce)-doped tungsten oxide nanostructures were synthesised using a simple solvothermal method from cerium chloride salt (CeCl3.7H2O) and tungsten hexachloride (WCl6) precursors. The as-prepared samples were thoroughly characterised using electron microscopies, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy. The electrochromic performance of different samples was evaluated using a custom-built UV-VIS spectrometer and an electrochemistry technique. The results showed that the as prepared samples underwent morphological evolution with the increase in the Ce/W molar ratio, from long, thin and bundled nanowires, through shorter and thicker nanowires to mixed nanowire bundles and nanoparticle agglomerates. From electrochemical testing, we found that the Ce-doped tungsten oxides exhibited higher optical contrasts of 44.3%, 49.7% and 39.4% for the 1 : 15, 1 : 10 and 1 : 5 Ce/W ratios respectively, compared with 37.4% for the pure W18O49 nanowires. The Ce/W = 1 : 15 samples presented an improved colouration efficiency of 67.3 cm2 C-1 against 62 cm2 C-1 for pure W18O49. This work demonstrated that the Ce doped W18O49 nanowires are very promising candidate materials for the design and construction of electrochemical chromic devices with largely improved efficiency, contrast and stability. The results from this work suggested that smart electrochromic devices based on current Ce-doped WOx nanomaterials could be further developed for future energy-related applications. PMID- 29464252 TI - A luminescent supramolecular Cu2I2(NH3)2-sandwiched Cu3(pyrazolate)3 adduct as a temperature sensor. AB - A highly luminescent supramolecular Cu2I2(NH3)2-sandwiched Cu3(pyrazolate)3 adduct was reported as a temperature sensor. The adduct is stabilized by the synergy of intermolecular Cu3I (pi acidbase), CuCu and NH interactions, to form a Cu8I2 cluster. The emission intensity exhibits a temperature-dependent effect in the solid state with a sensitivity of -0.685% K-1. DFT and TDDFT calculations revealed that the luminescence originates from the triplet state of Cu8I2 cluster centered charge transfer (3CC).

AB - Planar chiral [2.2]paracyclophane-based phosphine-phenol catalysts, which have a benzene ring spacer inserted between the pseudo-ortho-substituted [2.2]paracyclophanol skeleton and the diarylphosphino group, are highly suitable for enantioselective [3 + 2] annulations of allenoates and N-tosylimines. These catalysts can be tuned by changing the substituent on the benzene rings of the diarylphosphino group. The observed enantioselectivity of 92% is the highest reported to date for phosphine-catalyzed annulations of unsubstituted allenic esters and N-tosylaldimines. PMID- 29464255 TI - Plasmonic nose: integrating the MOF-enabled molecular preconcentration effect with a plasmonic array for recognition of molecular-level volatile organic compounds. AB - Timely detection of toxic vapor is vital for safeguarding people's lives. Herein, we design a plasmonic nose based on a zeolitic imidazolate framework (ZIF) encapsulated Ag nanocube array for ultratrace recognition of VOC vapor. The plasmonic nose enables in situ adsorption kinetics and recognition of various VOCs at ppm levels, eliminating false positives. Our approach provides a paradigm shift to next-generation, effective and specific gas sensors.

AB - We report the synthesis of air-stable Pd(i) dimer complexes featuring biaryl phosphine ligands. Catalytic experiments suggest that these complexes are competent precatalysts that can mediate cross-coupling amination reactions between aryl halides with both aliphatic and aromatic amine nucleophiles. This work represents an expansion of the air-stable precatalyst toolbox for Pd catalyzed cross-coupling transformations. PMID- 29464256 TI - Quantitative analysis of UV photolesions suggests that cyclobutane pyrimidine dimers produced in mouse skin by UVB are more mutagenic than those produced by UVC. AB - The amount of photolesions produced in DNA after exposure to physiological doses of ultraviolet radiation (UVR) can be estimated with high sensitivity and at low cost through an immunological assay, ELISA, which, however, provides only a relative estimate that cannot be used for comparisons between different photolesions such as cyclobutane pyrimidine dimer (CPD) and pyrimidine(6 4)pyrimidone photoproduct (64PP) or for analysis of the genotoxicity of photolesions on a molecular basis. To solve this drawback of ELISA, we introduced a set of UVR-exposed, calibration DNA whose photolesion amounts were predetermined and estimated the absolute molecular amounts of CPDs and 64PPs produced in mouse skin exposed to UVC and UVB. We confirmed previously reported observations that UVC induced more photolesions in the skin than UVB at the same dose, and that both types of UVR produced more CPDs than 64PPs. The UVR protection abilities of the cornified and epidermal layers for the lower tissues were also evaluated quantitatively. We noticed that the values of absorbance obtained in ELISA were not always proportional to the molecular amounts of the lesion, especially for CPD, cautioning against the direct use of ELISA absorbance data for estimation of the photolesion amounts. We further estimated the mutagenicity of a CPD produced by UVC and UVB in the epidermis and dermis using the mutation data from our previous studies with mouse skin and found that CPDs produced in the epidermis by UVB were more than two-fold mutagenic than those by UVC, which suggests that the properties of CPDs produced by UVC and UVB might be different. The difference may originate from the wavelength-dependent methyl CpG preference of CPD formation. In addition, the mutagenicity of CPDs in the dermis was lower than that in the epidermis irrespective of the UVR source, suggesting a higher efficiency in the dermis to reduce the genotoxicity of CPDs produced within it. We also estimated the minimum amount of photolesions required to induce the mutation induction suppression (MIS) response in the epidermis to be around 15 64PPs or 100 CPDs per million bases in DNA as the mean estimate from UVC and UVB-induced MIS. PMID- 29464257 TI - A fabrication method of gold coated colloidosomes and their application as targeted drug carriers. AB - Colloidosomes have attracted considerable attention in recent years because of their potential applications in a range of industries, such as food, bioreactors and medicine. However, traditional polymer shell colloidosomes leak low molecular weight encapsulated materials due to their intrinsic shell permeability. Here, we report aqueous core colloidosomes coated with a gold shell, which make the capsules impermeable. The shells can be ruptured using ultrasound. The gold coated colloidosomes are prepared by making an aqueous core capsule with a polymer shell and then adding HAuCl4, surfactant and l-ascorbic acid to form a second shell. We propose to use the capsules as drug carriers. The gold coated colloidosomes demonstrate a low cytotoxicity and after triggering, both encapsulated doxorubicin and broken gold fragments kill cancer cells. In addition, we set up a targeting model by modifying the gold shell colloidosomes using 4,4'-dithiodibutyric acid and crosslinking them with proteins-rabbit immunoglobulin G (IgG). Label-free surface plasmon resonance was used to test the specific targeting of the functional gold shells with rabbit antigen. The results demonstrate that a new type of functional gold coated colloidosome with non permeability, ultrasound sensitivity and immunoassay targeting could be applied to many medical applications. PMID- 29464258 TI - Reconstitution of composite actin and keratin networks in vesicles. AB - Although cytoskeletal networks are interpenetrating and interacting in living cells, very little is understood as to the effect their interaction has on their properties. Here, as a step towards elucidating the synergistic cellular role of these structural proteins, we investigate isolated keratin and actin composites and show how the in vitro network formation of keratin influences the properties of actin networks and vice versa. By encapsulating purified composite networks into vesicles and separating the time scales of network formation we are able to demonstrate that the actin network stabilizes keratin networks by providing an elastic resistance to their collapse in vitro.

AB - A facile and sensitive method with a tunable dynamic range has been proposed for the detection of Cu2+ based on the self-cleavage of Cu2+-specific DNAzyme and the Cu2+-based inhibition of HRP activity, and this method was applied to evaluate the copper species in healthy people and WD patients.

AB - An N-Heterocyclic Carbene (NHC) catalyzed biomimetic Stetter reaction was applied for the first time as a bioconjugation reaction to sensitive nucleoside-type biomolecules to provide original pyrrole linked nucleolipids. A versatile approach allowed the functionalization of thymidine at the three reactive positions (O-5', O-3' and N-3) providing a structural diversity oriented synthesis. This strategy was applied to the synthesis of an original glyconucleolipid amphiphile in the hope that the pyrrole aromatic moiety would induce additional self-assembling properties. PMID- 29464262 TI - Lysine-based amino-functionalized lipids for gene transfection: the influence of the chain composition on 2D properties. AB - The influence of the chain composition on the physical-chemical properties will be discussed for five transfection lipids containing the same lysine-based head group. For this purpose, the chain composition will be gradually varied from saturated tetradecyl (C14:0) and hexadecyl (C16:0) chains to longer but unsaturated oleyl (C18:1) chains with double bonds in the cis configuration. In this work, we investigated the lipids as Langmuir monolayers at the air-water interface in the absence and presence of calf thymus DNA applying different techniques such as infrared reflection absorption spectroscopy (IRRAS) and grazing incidence X-ray diffraction (GIXD). The replacement of saturated tetradecyl (C14:0) and hexadecyl (C16:0) chains by unsaturated oleyl (C18:1) chains increases the fluidity of the lipid monolayer: TH10 < TT10 < OH10 < OT10 < OO10 resulting in a smaller packing density. TH10 forms the stiffest and OO10 the most fluid monolayer in this structure-property study. OO10 has a higher protonation degree compared to the saturated lipids TT10 and TH10 as well as to the hybrids OT10 and OH10 because of a better accessibility of the amine groups. Depending on the bulk pH, different scenarios of DNA coupling to the lipid monolayers have been proposed. PMID- 29464263 TI - Homogeneous melting near the superheat limit of hard-sphere crystals. AB - A defect-free crystal can be superheated into a metastable state above its melting point and eventually melts via homogeneous nucleation. Further increasing the temperature leads to the metastable crystal becoming unstable and melting catastrophically once beyond its superheat limit. The homogeneous melting is not well studied near the superheat limit and this limit is difficult to measure accurately, even for the simplest model of hard-sphere crystals. Here our molecular-dynamics simulations identify its superheat limit at volume fraction philimit = 0.494 +/- 0.003, which is higher than the previous theoretical estimations. We found that the hard-sphere crystal at the superheat limit does not satisfy Born's melting criterion, but has a vanishing bulk modulus, i.e. a spinodal instability, which preempts other thermodynamic or mechanical instabilities. At the strong superheating regime, the nucleation deviates from the assumptions in the classical nucleation theory. In contrast to crystallization which often develops nuclei with various intermediate structures, the melting of face-centered cubic (fcc) hard-sphere crystal does not produce intermediate structures such as body-centered cubic (bcc) crystallites although bcc is more stable than fcc at the strong superheating regime. Moreover, we found that the time evolutions of the order parameters and the pressure all exhibit a compressed exponential function, in contrast to the stretched exponential relaxation of supercooled liquids. The compressed exponential functions have the same exponent, which poses a new challenge to theory. PMID- 29464264 TI - Push-pull D-pi-Ru-pi-A chromophores: synthesis and electrochemical, photophysical and second-order nonlinear optical properties. AB - The present work describes the one-pot synthesis and electrochemical, photophysical and second-order nonlinear optical (NLO) properties of a series of dipolar pi-delocalized Ru(ii) dialkynyl complexes. The eight new asymmetrical D pi-Ru-pi-A push-pull chromophores incorporate pyranylidene ligands as pro aromatic donor groups (D) and formaldehyde, indane-1,3-dione, pyrimidine or pyrimidinium as electron-attracting groups (A) separated by ruthenium bis acetylide fragments and pi-conjugated linkers. The second-order nonlinear optical (NLO) properties of all eight complexes were determined by the Electric-Field Induced Second Harmonic generation (EFISH) technique (operating at 1907 nm), and were compared to those of their purely organic analogs. All investigated compounds (organic and organometallic) exhibited positive MUbeta values, which dramatically increased for the complexes due to the presence of ruthenium in the pi-conjugated core. The second-order NLO response could also be easily modulated by changing the nature of alkynyl substituents. The most promising ruthenium complexes 7 and 8 of the series with the pyrimidinium fragment displayed MUbeta values of 14 000 * 10-48 esu. The effect of structural modifications on the redox and spectroscopic properties of the complexes was also studied. The intramolecular charge transfer (ICT) occurring through the ruthenium center of the push-pull sigma-dialkynyl complexes was investigated by combining experimental and theoretical data.

PMID- 29464268 TI - Reversible Dilation of Cerebral Macrovascular Changes in MELAS Episodes. AB - PURPOSE: To investigate the cerebral macrovascular changes as well as the relationship of large vessels and cerebral blood flow (CBF) in mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS) using magnetic resonance angiography (MRA) and arterial spin labeling (ASL) perfusion MR imaging (MRI). METHODS: A total of 20 patients diagnosed with MELAS (12 males, 8 females; mean age, 23.3 years) underwent conventional MRI, time-of-flight (TOF) MRA and three dimensional ASL. Follow-up scans were performed in 10 patients. The changes of cerebral arteries and branches on MRA images from both acute and recovery patients were independently evaluated by two radiologists. Lesion distribution and CBF were observed on the integrated maps of MRA and ASL. RESULTS: In 14 patients with clinical onsets, increased CBF was observed in all stroke-like lesions. Dilations of a single artery (four middle cerebral arteries, two posterior cerebral arteries) were found in six patients. Dilations of multiple arteries (two anterior cerebral arteries, seven middle cerebral arteries, six posterior cerebral arteries) were found in seven patients. Normal angiography was shown in one acute patient. Cortical terminal branches feeding the lesion areas were more obviously dilated than the main trunks. The dilated vessels returned to normal on follow-up scans concurrently with decreased CBF in nine patients who were resuscitated from episode attacks. Vasodilation was even seen in one preclinical patient who suffered a recurrent episode 50 days later. CONCLUSION: Reversible dilation of cerebral macrovascular changes could be a new feature of MELAS and a presumed reason for fluctuant CBF. It would shed new light on the mitochondrial angiopathy. PMID- 29464269 TI - Glioma grading by dynamic susceptibility contrast perfusion and 11C-methionine positron emission tomography using different regions of interest. AB - PURPOSE: The use of dynamic susceptibility contrast (DSC) perfusion and 11C methionine positron emission tomography (MET-PET) for glioma grading is currently not standardized. The purpose of this study was to identify regions of interest (ROIs) that enable the best performance and clinical applicability in both methods, as well as to evaluate the complementarity of DSC perfusion and MET-PET in spatial hotspot definition. METHODS: In 41 patient PET/MRI datasets, different ROIs were drawn: in T2-hyperintense tumour, in T2-hyperintense tumour and adjacent oedema and in tumour areas with contrast enhancement, altered perfusion or pathological radiotracer uptake. The performance of DSC perfusion and MET-PET using the different ROIs to distinguish high- and low-grade gliomas was assessed. The spatial overlap of hotspots identified by DSC perfusion and MET-PET was assessed visually. RESULTS: ROIs in T2 fluid attenuated inversion recovery (FLAIR) sequence-hyperintense tumour revealed the most significant differences between high- and low-grade gliomas and reached the highest diagnostic performance in both DSC perfusion (p = 0.046; area under the curve = 0.74) and MET-PET (p = 0.007; area under the curve = 0.80). The combination of methods yielded an area under the curve of 0.80. Hotspots were completely overlapped in one half of the patients, partially overlapped in one third of the patients and present in only one method in approximately 20% of the patients. CONCLUSIONS: For multi-parametric examinations with DSC perfusion and MET-PET, we recommend an ROI definition based on T2-hyperintense tumour. DSC perfusion and MET-PET contain complementary information concerning the spatial hotspot definition. PMID- 29464271 TI - [Noise-induced neurodegeneration in the central auditory pathway : An overview of experimental studies in a mouse model]. AB - BACKGROUND: A noise trauma induces central nervous system pathologies, which generate deficits in hearing and perception of sound. OBJECTIVE: Are degenerative mechanisms in the central auditory system a direct impact of overstimulation or an effect of acoustic deprivation? MATERIALS AND METHODS: Detection of cell death in a mouse model of noise-induced hearing loss at different times after single or repeated noise exposure. RESULTS: A single noise exposure (3 h, 115 dB SPL, 5-20 kHz) induces acute (<=1 day) and long-term (observation period 14 days) degeneration, particularly in subcortical structures. Repeated noise trauma is followed by pathologies in the auditory thalamus and cortex. CONCLUSION: Noise has a direct impact on basal structures of the central auditory system; a protection of cortical areas is possibly due to inhibitory neuronal projections. Degenerative mechanisms in higher structures of the pre-damaged system point to an increased impairment of complex processing of acoustic information. PMID- 29464270 TI - Diabetes modifies the role of prostanoids and potassium channels which regulate the hypereactivity of the rabbit renal artery to BNP. AB - Diabetic nephropathy is associated with increased risk of cardiovascular disease. B-type natriuretic peptide (BNP) plays an important role in cardiovascular pathophysiology and therapeutics. The aim of the present study was to investigate the influence of experimental diabetes on the mechanisms that regulate the relaxant response of the rabbit renal artery to BNP. Arterial relaxations to BNP were enhanced in diabetic rabbits. Indomethacin enhanced BNP-induced relaxation in control rabbits but showed no effect in diabetic rabbits. BNP-induced release of thromboxane A2 or prostacyclin was not different in both groups of animals. Iberiotoxin had no effect on relaxations to BNP in both groups of animals. Charybdotoxin displaced to the right the concentration-response curve to BNP in both group of animals, and inhibited BNP-induced relaxation only in diabetic rabbits. Glibenclamide did not modify the BNP-induced relaxations in control rabbits, but inhibited it in diabetic rabbits. These results suggest that diabetes induces hypereactivity of the rabbit renal artery to BNP by mechanisms that at least include (1) a reduced vasoconstrictor influence of arachidonic acid metabolites via cyclooxygenase 2, which is not related with changes in thromboxane A2 and prostacyclin release from the arterial wall and (2) a selectively increased modulatory activity of KATP and endothelial IKCa channels. PMID- 29464272 TI - Quantification of organic solvents in aquatic toys and swimming learning devices and evaluation of their influence on the smell properties of the corresponding products. AB - Based on the observation that the characteristic odour of inflatable aquatic toys for children is predominantly caused by residues of hazardous organic solvents, the concentrations of cyclohexanone, isophorone and phenol were determined in a selection of 20 products obtained from online suppliers located in Germany. Analytes were extracted with dichloromethane after the addition of non-labelled internal standards, and the volatile fraction was isolated using solvent-assisted flavour evaporation (SAFE). Extracts were then concentrated by Vigreux distillation and analysed by means of gas chromatography with mass spectrometric detection (GC-MS). Furthermore, each sample was evaluated regarding its specific olfactory properties by an expert sensory panel. While some samples did not contain significant amounts of solvents, cyclohexanone concentrations above the lower limit of quantification (LLOQ) were determined in nine samples with six samples containing high concentrations ranging from about 1 to 7 g/kg cyclohexanone. Isophorone concentrations above the LLOQ were observed in eight samples. Thereby, six products contained between 0.3 and 1.6 g/kg isophorone and the remaining two samples contained even about 5 g/kg isophorone, each. Likewise, phenol concentrations exceeded the LLOQ in 14 cases, with four samples containing elevated amounts ranging from about 140 to 280 mg/kg phenol. PMID- 29464273 TI - [Perianal inflammatory diseases : Classification and imaging]. AB - During the past 30 years, classifications and scoring systems have been developed in order to evaluate and objectify the degree and activity of anorectal fistulas. Only a few of these disease-specific instruments have been adopted into daily clinical routine. Generally, clinicians tend to use global medical judgement rather than numeric activity indices, which often seem complex and time consuming. Activity scores in Crohn disease, however, appeared to be very useful in clinical trials regarding evaluation of therapy response. Thus, activity indices must be simple and reproducible. The years 1976 and 1995, in which the Parks Classification and Perianal Disease Activity Index (PDAI) were established, can be considered milestone years for classifying patients with anorectal fistulizing disease. These instruments should be recognized at present as the gold standard for evaluating the complexity as well as the severity of anorectal fistulas and perianal Crohn disease. PMID- 29464274 TI - Percutaneous microwave ablation for local control of metastatic renal cell carcinoma. AB - PURPOSE: The purpose of the article is to evaluate the safety and oncologic efficacy of microwave ablation for metastatic renal cell carcinoma (mRCC). MATERIALS AND METHODS: From September 2011 to December 2016, 33 mRCC were ablated in 18 patients using percutaneous microwave ablation. Sites of mRCC include retroperitoneum (n = 12), contralateral kidney (n = 6), liver (n = 6), lung (n = 5), adrenal gland (n = 5). Technical success, local, and distant tumor progression, and complications were assessed at immediate and follow-up imaging. The Kaplan-Meier method was used for survival analysis. RESULTS: Technical success was achieved for 33/33 (100%) mRCC tumors. Ablation provided durable local control for 28/30 (93%) mRCC tumors in 17 patients at a median duration of clinical and imaging follow-up of 1.6 years (IQR 0.7-3.6) and 0.8 years (IQR 0.5 2.7), respectively. In-hospital and perioperative mortality was 0%. There were 5 (15%) procedure-related complications including one high-grade event (Clavien Dindo III). Four patients have died from mRCC at a median of 1.3 years (range 0.7 5.1) following ablation. Estimated OS (95% CI number still at risk) at 1, 2, and 5 years were 86% (53-96%, 11), 75% (39-92%, 8), and 75% (39-92%, 3), respectively. CONCLUSIONS: Microwave ablation of oligometastatic renal cell carcinoma is safe and provides durable local control in appropriately selected patients. PMID- 29464275 TI - Fat halo sign. PMID- 29464276 TI - After the fall: improving osteoporosis treatment following hip fracture. AB - : Osteoporotic hip fractures can be life changing and can increase mortality. Treatment of osteoporosis following hip fracture is often delayed. We began offering osteoporosis medication during hospitalization for hip fracture, dramatically increasing the number of patients meeting standard of care. INTRODUCTION: Osteoporotic hip fracture is a debilitating condition with major morbidity and mortality implications. Osteoporosis medication given within 90 days of hip fracture improves mortality and reduces risk of future fractures. The aim of this project was to improve rates of timely osteoporosis treatment following fragility hip fracture. METHODS: This was a two-step intervention utilizing the Plan-Do-Study-Act cycle, beginning with resident-focused education in cycle 1. In cycle 2, we offered osteoporosis medication to inpatients for hip fracture with help from a new electronic order set. RESULTS: Prior to this intervention, 32% of patients received osteoporosis medication within 90 days of fragility hip fracture; this improved to 81% after intervention. CONCLUSIONS: Resident education and an electronic order set dramatically improved the percentage of patients meeting standard of care with osteoporosis pharmacotherapy following fragility fracture. PMID- 29464277 TI - Health-related quality of life during the first year after a hip fracture: results of the Mexican arm of the International Cost and Utility Related to Osteoporotic Fractures Study (MexICUROS). AB - : We investigated changes in health-related quality of life (HRQoL) due to hip fracture in Mexican adults aged >= 50 years during the first year post-fracture. Mean accumulated loss was 0.27 quality-adjusted life years (QALYs). HRQoL before fracture was the main contributor to explain the loss of QALYs. INTRODUCTION: We aimed to estimate the health-related quality of life (HRQoL) loss over 1 year in patients sustaining a hip fracture in Mexico. METHODS: Individuals aged >= 50 years old with diagnosis of a low-energy-induced hip fracture enrolled in the International Costs and Utilities Related to Osteoporotic Fractures Study (ICUROS) composed the study population. After a recall of their own pre-fracture status, HRQoL was prospectively collected in three phases over 12 months of follow-up using EQ-5D-3L. The UK preference weight set was applied to calculate the utility values. The accumulated quality-adjusted life years (QALYs) loss in the first year post-fracture was estimated using the trapezoid method. Multivariate regression analysis allowed identifying determinants of QALYs loss. RESULTS: One hundred ninety-three patients (mean +/- SD age 77.2 +/- 9.9 years; 80% women; 15.5% with prior fracture in the last 5 years; 78% in low-income category) were evaluated. Mean (95% CI) utility value before fracture was 0.64 (0.59-0.68). It dropped to 0.01 (0.01-0.02) immediately after fracture and then improved to 0.46 (0.42-0.51) and 0.60 (0.55-0.64) at 4 and 12 months post fracture, respectively. Disregarding fracture-related mortality, accumulated QALYs loss over the first year was 0.27 (0.24-0.30) QALYs. Mobility, self-care, and usual activities were the most affected domains throughout the whole year. HRQoL before fracture was the main contributor to explain the loss of QALYs. CONCLUSIONS: Hip fractures reduce dramatically the HRQoL, with the loss sustained at least over the first year post-fracture in Mexico. The utility values derived from this study can be used in future economic evaluations. PMID- 29464278 TI - Biochemical Responses in Freshwater Fish Exposed to Insecticide Propoxur. AB - Although designed to control pests selectively, there is some evidence that environmental contamination by pesticides increases risks for humans and wildlife. In the present study, we evaluated biomarkers of oxidative stress in Astyanax jacuhiensis exposed to (5, 15 and 30 ug L-1) of carbamate Propoxur (PPX) for 96 h. Glutathione S-transferase (GST) in liver and gills showed reduced activity in all PPX concentrations tested. Acetylcholinesterase (AChE) activities reduced in brain and muscle at concentrations 15 and 30 ug L-1 of PPX. Lipid peroxidation (LPO) and hydrogen peroxide (HP) had no significant differences. In the brain, protein carbonyl (PC) increased in all groups treated with PPX. Although PPX is a selective pesticide, it causes oxidative damage and enzyme alteration in fish. This study pointed out some biomarkers that could be used to assess effects of environmentally relevant concentrations of pesticides, and infer about studies using fish as bioindicator. PMID- 29464279 TI - Biodegradability of Chlorophenols in Surface Waters from the Urban Area of Buenos Aires. AB - Biodegradability of 2-Chlorophenol (2-CP), 3-Chlorophenol (3-CP), 4-Chlorophenol (4-CP), 2,4-Dichlorophenol (2,4-DCP) and 2,4,6 Trichlorophenol (2,4,6-TCP) has been tested in surface waters in the urban area of Buenos Aires. Samples were taken from the La Plata River and from the Reconquista and Matanza-Riachuelo basins, with a total amount of 18 sampling points. Water quality was established measuring chemical oxygen demand (COD), biochemical oxygen demand (BOD5), and both Escherichia coli and Enterococcus counts. Biodegradability was carried out by a respirometric method, using a concentration of 20 mg L-1 of chlorophenol, and the surface water as inoculum. Chlorophenols concentration in the same water samples were simultaneously measured by a solid phase microextraction (SPME) procedure followed by gas chromatography-mass spectrometry (GC-MS). 2,4-DCP was the most degradable compound followed by 2,4,6-TCP, 4-CP, 3-CP and 2-CP. Biodegradability showed no correlation with compound concentration. At most sampling points the concentration was below the detection limit for all congeners. Biodegradability does not correlate even with COD, BOD5, or fecal contamination. Biodegradability assays highlighted information about bacterial exposure to contaminants that parameters routinely used for watercourse characterization do not reveal. For this reason, they might be a helpful tool to complete the characterization of a site. PMID- 29464280 TI - [Internal emergency cases at the interface of outpatient and inpatient - part 2]. PMID- 29464281 TI - Varying susceptibility of clinical and environmental Scedosporium isolates to chemical oxidative stress in conidial germination. AB - Scedosporium species are opportunistic pathogens causing a great variety of infections in both immunocompetent and immunocompromised individuals. The Scedosporium genus ranks the second among the filamentous fungi colonizing the airways of patients with cystic fibrosis (CF), after Aspergillus fumigatus, and most species are capable to chronically colonize the respiratory tract of these patients. Nevertheless, few data are available regarding evasion of the inhaled conidia to the host immune response. Upon microbial infection, macrophages and neutrophils release reactive oxygen species (ROS). To colonize the respiratory tract, the conidia need to germinate despite the oxidative stress generated by phagocytic cells. Germination of spores from different clinical or environmental isolates of the major Scedosporium species was investigated in oxidative stress conditions. All tested species showed susceptibility to oxidative stress. However, when comparing clinical and environmental isolates, differences in germination capabilities under oxidative stress conditions were seen between species as well as within each species. Among environmental isolates, Scedosporium aurantiacum isolates were the most resistant to oxidative stress whereas Scedosporium dehoogii were the most susceptible. Overall, the differences observed between Scedosporium species in the capacity to germinate under oxidative stress conditions could explain their varying prevalence and pathogenicity. PMID- 29464283 TI - [Osteoarthritis of the shoulder: pathogenesis, diagnostics and conservative treatment options]. AB - PATHOGENESIS: Osteoarthritis of the shoulder is characterized by a progressive degenerative process, which is based on chronic inflammation with intra-articular release of different cytokines and proteolytic enzymes. The main predisposing factors are a history of trauma or surgery, as well as chronic overuse or instability of the glenohumeral joint. Affected patients especially suffer from impaired joint function and pain, which are often associated with cognitive and psychosocial restrictions. DIAGNOSTICS: Possible co-pathologies have to be evaluated carefully both clinically and radiologically as they must be taken into account in the therapeutic procedure. If arthroplasty of the shoulder is planned, a pre-operative CT scan is mandatory in order to evaluate the bone stock of the glenoid, which has a decisive influence on the choice of implant. TREATMENT: Conservative treatment options are oral pain medication, physical therapy, and intra-articular injections, whereby, in comparison to corticosteroids, hyaluronic acid seems to be advantageous especially with respect to the duration of a positive clinical effect. PMID- 29464284 TI - Degradation of the mitochondrial complex I assembly factor TMEM126B under chronic hypoxia. AB - Cell stress such as hypoxia elicits adaptive responses, also on the level of mitochondria, and in part is mediated by the hypoxia-inducible factor (HIF) 1alpha. Adaptation of mitochondria towards acute hypoxic conditions is reasonably well understood, while regulatory mechanisms, especially of respiratory chain assembly factors, under chronic hypoxia remains elusive. One of these assembly factors is transmembrane protein 126B (TMEM126B). This protein is part of the mitochondrial complex I assembly machinery. We identified changes in complex I abundance under chronic hypoxia, in association with impaired substrate-specific mitochondrial respiration. Complexome profiling of isolated mitochondria of the human leukemia monocytic cell line THP-1 revealed HIF-1alpha-dependent deficits in complex I assembly and mitochondrial complex I assembly complex (MCIA) abundance. Of all mitochondrial MCIA members, we proved a selective HIF-1 dependent decrease of TMEM126B under chronic hypoxia. Mechanistically, HIF-1alpha induces the E3-ubiquitin ligase F-box/WD repeat-containing protein 1A (beta TrCP1), which in turn facilitates the proteolytic degradation of TMEM126B. Attenuating a functional complex I assembly appears critical for cellular adaptation towards chronic hypoxia and is linked to destruction of the mitochondrial assembly factor TMEM126B. PMID- 29464286 TI - Dentoalveolar characteristics in children with juvenile idiopathic arthritis. AB - PURPOSE: Juvenile idiopathic arthritis (JIA) is an autoimmune disease with multiple potential causal factors. In case of temporomandibular joint (TMJ) affection, the inflammatory reaction can result in restricted mandibular growth with implied skeletal and facial deformities. Aim of the present study was to examine dentoalveolar and occlusion characteristics in children with JIA. PATIENTS AND METHODS: The sample consisted of 66 children (27 boys, 39 girls) with JIA. Thirty-three of them showed unilateral or bilateral condylar destruction, while the other half did not manifest any TMJ involvement. Corresponding dental casts of these patients were evaluated and Angle classification, overjet, overbite, crossbite, crowding, and ectopic teeth were registered. All dental casts were subsequently scanned and digitized to analyze 26 additional variables. Subgroups according to sex and condylar affection were formed. Statistical analysis was performed using Fisher's least significant difference (LSD) post hoc test of analysis of variance (ANOVA). RESULTS: The prevalence of Class II, division 1 malocclusion in this JIA sample was high (28.8%). Compared to girls, boys had significantly greater dental arch widths and lengths. The group with bilateral condylar affection had significantly decreased lower arch length and increased irregularity index (p < 0.035) compared to the non-affected group. CONCLUSIONS: Bilateral condylar involvement in children with JIA seems to reduce the lower arch length, while increasing the irregularity index of the lower front teeth. PMID- 29464285 TI - Revisiting the metabolic syndrome: the emerging role of aquaglyceroporins. AB - The metabolic syndrome (MetS) includes a group of medical conditions such as insulin resistance (IR), dyslipidemia and hypertension, all associated with an increased risk for cardiovascular disease. Increased visceral and ectopic fat deposition are also key features in the development of IR and MetS, with pathophysiological sequels on adipose tissue, liver and muscle. The recent recognition of aquaporins (AQPs) involvement in adipose tissue homeostasis has opened new perspectives for research in this field. The members of the aquaglyceroporin subfamily are specific glycerol channels implicated in energy metabolism by facilitating glycerol outflow from adipose tissue and its systemic distribution and uptake by liver and muscle, unveiling these membrane channels as key players in lipid balance and energy homeostasis. Being involved in a variety of pathophysiological mechanisms including IR and obesity, AQPs are considered promising drug targets that may prompt novel therapeutic approaches for metabolic disorders such as MetS. This review addresses the interplay between adipose tissue, liver and muscle, which is the basis of the metabolic syndrome, and highlights the involvement of aquaglyceroporins in obesity and related pathologies and how their regulation in different organs contributes to the features of the metabolic syndrome. PMID- 29464287 TI - Insertion torque values and success rates for paramedian insertion of orthodontic mini-implants : A retrospective study. AB - OBJECTIVES: Orthodontic mini-implants (OMIs) are a reliable method to provide temporary orthodontic anchorage. We hypothesized that there is an optimal insertion torque (<10 Ncm) that can be used to ensure the success of self drilling OMIs in the paramedian region. PATIENTS AND METHODS: Included were 40 (26 females, 14 males) consecutive patients requiring palatal skeletal anchorage. Mean age was 17.3 years (range 11.0-44.6 years) for female patients and 15.7 years (range 10.6-36.9 years) for male patients. A total of 22 patients received a Beneslider according to Wilmes for the distalization of maxillary first molars, 10 patients received a Mesialslider for the mesialization of maxillary first molars, and 8 patients received a bone-borne rapid palatal expansion (RPE) appliance. Torque values of 10-15 Ncm were recorded in 46.3% of the OMIs and 15 20 Ncm in 35% of OMIs. OMIs that endured the orthodontic force applied for >=6 months were considered as success. RESULTS: The overall success rate was 98.8%. No significant differences were found between insertion torque values with respect to the right and left sides, Jarabak's ratio, facial axis, and Frankfort to mandibular plane angle. There were no significant differences in the OMIs insertion torques with regard to the different appliances. No association was found between insertion torque and vertical skeletal morphology. CONCLUSION: With an overall success rate of 98.8%, the study hypothesis that greater insertion torque (>10 Ncm) will decrease the success rate and increase palatal OMI failure was rejected. PMID- 29464288 TI - Mandibular fossa morphology during therapy with a fixed functional orthodontic appliance : A magnetic resonance imaging study. AB - OBJECTIVE: During therapy of distoclusion entailing a rigid, fixed orthodontic appliance, the mandibular fossa and condyle are ideally remodeled, while dentoalveolar effects occur through adaptive mechanisms. Adaptive processes, especially in the fossa region, have not been adequately investigated. Our magnetic resonance imaging (MRI) investigation aimed to assess the effects of therapy with a functional mandibular advancer (FMA) on mandibular fossa morphology. PATIENTS AND METHODS: We monitored via MRI the therapeutic course of 25 patients at three time points. Visual findings and metric assessments were carried out in the sagittal plane. Three-dimensional (3D) reconstructions of the joint structure of two exemplary patients were also made. RESULTS: Visual examinations of the MRI slices at the three time points revealed no changes in fossa shape in any of the 50 temporomandibular joints. Lateral comparisons showed that the morphology of the fossae of all 25 patients was identical. Metric analysis demonstrated no significant alterations in width, depth, or in their ratio, not even laterally. Nine measurements of the distances between the porion, mandibular fossa, and articular eminence revealed no significant changes in total or on the left and right sides, or intralaterally. CONCLUSION: The visual findings and metric analyses of parasagittal MRI slices did not indicate any morphological changes in the mandibular fossa or articular eminence in patients with distoclusion treated via a rigid, fixed orthodontic appliance. However, special reworking of the MRI data facilitated reconstruction of the surfaces of joint structures in 3D. This new method makes it possible to depict more accurately and noninvasively the adaptive mechanisms not ascertainable via metric methods and to assess them as 3D structures. PMID- 29464289 TI - Long-term effects of Class II orthodontic treatment on oral health. AB - AIM: To investigate the long-term (>=15 years) benefit of orthodontic Class II treatment (Tx) on oral health (OH). SUBJECTS AND METHODS: All patients (Department of Orthodontics, University of Giessen, Giessen, Germany) who underwent Class II correction (Herbst-multibracket Tx, end of active Tx >= 15 years ago) and agreed to participate in a recall (clinical examination, interview, impressions, and photographs) were included. Records after active Tx were used to assess the long-term OH effects. Data were compared to corresponding population-representative age-cohorts as well as to untreated Class I controls without orthodontic Tx need during adolescence. RESULTS: Of 152 treated Class II patients, 75 could be located and agreed to participate at 33.7 +/- 3.0 years of age (pre-Tx age: 14.0 +/- 2.7 years). The majority (70.8%) were fully satisfied with their teeth and with their masticatory system. The Decayed, Missing, Filled Teeth Index (DMFT) was 7.1 +/- 4.8 and, thus, almost identical to that of the untreated Class I controls (7.9 +/- 3.6). In contrast, the DMFT in the population representative age-cohort was 56% higher. The determined mean Community Periodontal Index (CPI) maximum score (1.6 +/- 0.6) was also comparable to the untreated Class I controls (1.7 +/- 0.9) but in the corresponding population representative age-cohort it was 19-44% higher. The extent of lower incisor gingival recessions did not differ significantly between the treated Class II participants and the untreated Class I controls (0.1 +/- 0.2 vs. 0.0 +/- 0.1 mm). CONCLUSION: Patients with orthodontically treated severe Class II malocclusions had a lower risk for oral health impairment than the general population. The risk corresponded to that of untreated Class I controls (without orthodontic Tx need during adolescence). PMID- 29464291 TI - [Rupture of the scapholunate intercarpal ligament]. AB - Complete rupture of the scapholunate (SL) ligament can cause a dissociative carpal instability (CID). These ligamentous lesions are caused by a fall from a limited height of approximately 1 m or a fall, e. g. when playing handball or soccer. For a freshly injured wrist joint, the X-ray signs of a static instability (after excluding a fracture) are a SL distance >=3 mm, a SL angle >60 degrees , and a dorsal displacement of the proximal scaphoid pole. Dynamic instabilities are best seen in kinematography of the wrist joint. Early ligament refixation is mandatory, ideally done in the first week after the incident or at least within the first 3 weeks. The cornerstone of the procedure is an anatomic reduction of the SL joint stabilized with K-wires for 8 weeks. In older lesions, ligament transfer or ligamentoplasty using a tendon transfer may add to stability but have so far not achieved a reliable joint alignment despite usually good functional results. It appears that the reduction of the proximal scaphoid pole deserves more attention. PMID- 29464290 TI - Does orthodontic treatment have a permanent effect on tooth color? : A systematic review and meta-analysis. AB - OBJECTIVES: Aim of this systematic review was to assess the effect of orthodontic treatment with fixed appliances on the tooth color of patients. METHODS: Nine databases were searched up to May 2017 for clinical cohort studies on the effect of fixed appliance treatment on tooth color. After elimination of duplicate studies, data extraction, and risk of bias assessment according to the Cochrane guidelines, random effects meta-analyses of mean differences (MD) or means and their 95% confidence intervals (CIs) were performed, followed by GRADE (Grading of Recommendations Assessment, Development and Evaluation) assessment of the quality of evidence. RESULTS: Three nonrandomized and one randomized study with a total of 138 patients (46% male, 54% female) with average age of 15.7 years were included. Tooth color of treated patients was significantly altered during or after orthodontic treatment (4 studies; average of 3.2 ?E units; 95% CI = 2.0-4.4 ?E units), which was more than the variation among controls (1 study; MD = 1.9 ?E units; 95% CI = 1.7-2.2 ?E units). However, the quality of evidence was very low, due to the inclusion of nonrandomized studies, bias, and imprecision. Re-analysis of raw study data indicated that significant differences in clinically discernable treatment-induced color changes were seen between chemically and light-cured adhesives and among the various tooth categories. CONCLUSION: Existing evidence of very low quality indicates that orthodontic treatment might be associated with alterations of tooth color, which are however not consistently clinically discernible. Treatment-induced color alterations might be dependent on bonding material and tooth type, but evidence supporting this is weak. PMID- 29464292 TI - [Display technologies for augmented reality in medical applications]. AB - BACKGROUND: One of the main challenges for modern surgery is the effective use of the many available imaging modalities and diagnostic methods. Augmented reality systems can be used in the future to blend patient and planning information into the view of surgeons, which can improve the efficiency and safety of interventions. OBJECTIVE: In this article we present five visualization methods to integrate augmented reality displays into medical procedures and the advantages and disadvantages are explained. MATERIAL AND METHODS: Based on an extensive literature review the various existing approaches for integration of augmented reality displays into medical procedures are divided into five categories and the most important research results for each approach are presented. RESULTS: A large number of mixed and augmented reality solutions for medical interventions have been developed as research prototypes; however, only very few systems have been tested on patients. CONCLUSION: In order to integrate mixed and augmented reality displays into medical practice, highly specialized solutions need to be developed. Such systems must comply with the requirements with respect to accuracy, fidelity, ergonomics and seamless integration into the surgical workflow. PMID- 29464293 TI - [Kirschner wire osteosynthesis for fractures in childhood: bury wires or not? : Results of a survey on care reality in Germany]. AB - INTRODUCTION: Kirschner wire osteosynthesis is considered to be the standard technique for surgical fixation of displaced supracondylar humeral and distal radial fractures in children. The Kirschner wires can be left exposed or buried under the skin. Advantages of the epicutaneous technique are, e. g. the efficiency (cost, effort) and the possibility for wire removal without the necessity of a second anesthesia. On the other hand, there is a concern about higher infection rates as well as traumatization of the children due to externally visible wires. METHODS: A web-based survey of members of the DGU, DGOU, DGOOC, and the pediatric traumatology section of the DGU (SKT) was performed to evaluate current treatment concepts in Germany. The pros and cons for each technique were recorded and the need for a clinical study was examined. In addition, a cost analysis was performed for both methods. The results from the literature are summarized and discussed. RESULTS: A total of 710 questionnaires were evaluated. The majority of the respondents were trauma surgeons working in a hospital (80%). The buried technique was superior in both fracture groups (supracondylar humeral fractures 73% and distal radius fractures 69%), whereas a relevant difference could be found depending on the profession. The main reason for the subcutaneous technique was anxiety or observed higher infections using the epicutaneous technique. CONCLUSION: In Germany, the majority of wires are buried under the skin due to a fear of higher infection rates. In addition, other influencing factors such as pain and traditional approaches play a significant role. With respect to the results in the literature as well as a possible improvement of efficiency and avoidance of a second anesthesia, a multicentric clinical study seems necessary in the future to compare both techniques. PMID- 29464294 TI - [Defect coverage of fingers and thumb : Indications and treatment]. AB - Due to the exposure of the hands in the daily routine, defect wounds of the hand are common. The injury severity varies and ranges from small fingertip defects to large soft tissue lesions with exposed tendons, nerves and vessels. The complete extent of the soft tissue defect is often only recognizable after meticulous debridement. A considerable variety of techniques for defect coverage are available to the surgeon but the actual challenge is to select the most appropriate procedure which will result in the smallest possible residual defect. This review article presents the diagnostic approaches to soft tissue defects of the hand and current treatment options. PMID- 29464295 TI - [Evolution and principles of intramedullary locked nailing]. AB - Key factors for successful osteosynthetic fracture stabilization are anatomical fracture reduction, restoration of axis and torsion alignment as well as tissue preserving operative techniques. In long bone fractures, the use of intramedullary long bridging nailing offers ideal conditions for bone healing, as axial and rotational stability is provided by canal-filling nails and locking screws. In addition, the tissue in the fracture region is protected as the intramedullary nail insertion is distant from the fracture. The indication spectrum for modern intramedullary locked nailing includes diaphyseal fractures of long bones, metaphyseal fractures and reconstructions, as well as treatment of nonunion, osteotomy and arthrodesis of the lower extremities. Continuous improvements in nail design and instrumentation as well as the introduction of anatomical reconstruction nails will optimize the spectrum and effectiveness of intramedullary osteosynthesis even further.

PMID- 29464300 TI - Association between vaginal parity and rectocele. AB - INTRODUCTION AND HYPOTHESIS: Rectocele is common in parous women but also seen in nulliparae. This study was designed to investigate the association between vaginal parity and descent of the rectal ampulla/rectocele depth as determined by translabial ultrasound (TLUS). METHODS: This retrospective observational study involved 1296 women seen in a urogynaecological centre. All had undergone an interview, clinical examination and 4D ultrasound (US) imaging supine and after voiding. Offline analysis of volume data was undertaken blinded against other data. Rectal ampulla position and rectocele depth were measured on Valsalva. A pocket depth of 10 mm was used as a cutoff to define rectocele on imaging. RESULTS: Most women presented with prolapse (53%, n = 686); 810 (63%) complained of obstructed defecation (OD). Clinically, 53% (n = 690) had posterior compartment prolapse with a mean Bp of -1 [standard deviation (SD)1.5; -3 to 9 cm]. Mean descent of the rectal ampulla was 10 mm below the symphysis (SD 15.8; 50 to 41). A rectocele on imaging was found in 48% (n = 618). On univariate analysis, OD symptoms were strongly associated with rectal descent, rectocele depth and rectocele on imaging (all P < 0.001). The prevalence of a rectocele seen on imaging increased with vaginal parity (P < 0.001). One-way analysis of variance (ANOVA) of vaginal parity against rectal descent and rectocele depth showed a dose-response relationship (both P < 0.001). CONCLUSIONS: Vaginal parity was strongly associated with descent of the rectal ampulla and rectocele depth. This relationship approximated dose-response characteristics, with the greatest effect due to the first vaginal delivery. PMID- 29464301 TI - Outcomes of minimally invasive abdominal sacrocolpopexy with resident operative involvement. AB - INTRODUCTION AND HYPOTHESIS: Resident involvement in complex surgeries is under scrutiny with increasing attention paid to health care efficiency and quality. Outcomes of urogynecological surgery with resident involvement are poorly described. We hypothesized that resident surgical involvement does not influence perioperative outcomes in minimally invasive abdominal sacrocolpopexy (ASC). METHODS: Using the 2006-2012 National Surgical Quality Improvement Program database, we identified 450 cases of laparoscopic or robotic ASC performed with resident involvement. Resident operative participation was stratified by experience (junior [PGY 1-3] vs senior level [PGY >=4]). The primary outcome was operative time, and multinomial logistic regression was used to determine the effects of resident involvement and experience. Chi-squared analyses were used to assess the relationship between resident participation with length of stay (LOS) and 30-day complications and readmissions. RESULTS: Residents participated in 74% (n = 334) of these surgeries, and these cases were significantly longer (median 220 vs 195 min, p = 0.03). On multivariate analysis, senior level resident involvement was associated with longer operative times across all time intervals compared with <2 h (2 to <=4 h relative risk reduction [RRR] 4.1, p = 0.007, CI 1.47-11.40; 4 to <=6 h RRR 6.6, p = 0.001, CI 2.23-19.44; >=6 h RRR 4.7, p = 0.020, CI 1.28-17.43). Resident participation was not associated with LOS, readmissions, or complications. CONCLUSIONS: Senior level resident involvement in minimally invasive ASC is associated with longer operative times, with no association with LOS or adverse perioperative outcomes. The educational benefit of surgical training does not adversely affect patient outcomes for ASC. PMID- 29464303 TI - Brief ethanol exposure and stress-related factors disorganize neonatal breathing plasticity during the brain growth spurt period in the rat. AB - RATIONALE: The effects of early ethanol exposure upon neonatal respiratory plasticity have received progressive attention given a multifactorial perspective related with sudden infant death syndrome or hypoxia-associated syndromes. The present preclinical study was performed in 3-9-day-old pups, a stage in development characterized by a brain growth spurt that partially overlaps with the 3rd human gestational trimester. METHODS: Breathing frequencies and apneas were examined in pups receiving vehicle or a relatively moderate ethanol dose (2.0 g/kg) utilizing a whole body plethysmograph. The experimental design also considered possible associations between drug administration stress and exteroceptive cues (plethysmographic context or an artificial odor). Ethanol exposure progressively exerted a detrimental effect upon breathing frequencies. A test conducted at PD9 when pups were under the state of sobriety confirmed ethanol's detrimental effects upon respiratory plasticity (breathing depression). RESULTS: Pre-exposure to the drug also resulted in a highly disorganized respiratory response following a hypoxic event, i.e., heightened apneic episodes. Associative processes involving drug administration procedures and placement in the plethysmographic context also affected respiratory plasticity. Pups that experienced intragastric administrations in close temporal contiguity with such a context showed diminished hyperventilation during hypoxia. In a 2nd test conducted at PD9 while pups were intoxicated and undergoing hypoxia, an attenuated hyperventilatory response was observed. In this test, there were also indications that prior ethanol exposure depressed breathing frequencies during hypoxia and a recovery normoxia phase. CONCLUSION: As a whole, the results demonstrated that brief ethanol experience and stress-related factors significantly disorganize respiratory patterns as well as arousal responses linked to hypoxia in neonatal rats.

PMID- 29464302 TI - Nicotine drug discrimination and nicotinic acetylcholine receptors in differentially reared rats. AB - RATIONALE: Individuals vary in sensitivity to the behavioral effects of nicotine, resulting in differences in vulnerability to nicotine addiction. The role of rearing environment in determining individual sensitivity to nicotine is unclear. The neuropharmacological mechanisms mediating the effect of rearing environment on the behavioral actions of nicotine are also poorly understood. OBJECTIVES: The contribution of rearing environment in determining the sensitivity to the interoceptive effects of nicotine was determined in rats reared in isolated conditions (IC) or enriched conditions (EC). The role of dopamine receptors and alpha4beta2*-nicotinic acetylcholine (nACh) receptors in mediating the differential effect of IC and EC on the interoceptive action of nicotine was determined. METHODS: The interoceptive action of nicotine was measured as the discriminative stimulus effect of nicotine. Mecamylamine- and eticlopride inhibition of the nicotine stimulus were used to examine nACh and dopamine receptors, respectively. alpha4beta2*-nACh receptor expression in the mesolimbic dopamine pathway was determined by quantitative autoradiography of [125I] epibatidine binding. RESULTS: EC-reared rats are less sensitive than IC-reared rats to the discriminative stimulus effects of nicotine at all but maximally effective doses. Mecamylamine inhibited the nicotine stimulus threefold more potently in EC-reared rats (IC50 = 0.25 mg/kg) compared to IC-reared rats (IC50 = 0.75 mg/kg); eticlopride inhibition was not different. [125I]-epibatidine binding in the ventral tegmental area of EC-reared rats was reduced (2.8 +/- 0.3 fmol) compared to that of IC-reared rats (4.0 +/- 0.4 fmol); there was no difference in the nucleus accumbens. CONCLUSIONS: Rearing environment regulates the sensitivity to the interoceptive effects of nicotine and alpha4beta2*-nACh receptor expression in the mesolimbic dopamine pathway.

AB - Neuroendocrine tumors of the small intestines are a rare disease with an incidence of 1 per 100,000 of the population; however, they account for over 20% of all neuroendocrine tumors and are the most common malignancy of the small intestines. Diagnosis is often made at a late stage of the disease, as the clinical symptoms are unspecific. Approximately one third of all patients show hepatic metastases at the time of diagnosis. There is no correlation between tumor size and tumor stage. Even small tumors <10 mm harbor the risk for lymphatic and distant metastases so that the extent of surgery is not determined by the size of the primary tumor. The intestinal-sparing resection with systematic lymphadenectomy along the superior mesenteric artery and removal of the retropancreatic lymph nodes is recommended even in localized stages of the disease. PMID- 29464307 TI - [Pathology of early stage cancer of the gastrointestinal tract : Definition, principles and diagnosis]. AB - BACKGROUND: Early stage cancers of the gastrointestinal tract are malignant tumors that are eligible for local therapy regimens and show an excellent prognosis. OBJECTIVE: This article explains the histopathological aspects of the various diseases that are covered by this topic. METHODS: Organ-preserving therapies are discussed according to their locations and under consideration of the current guidelines and the relevant literature. RESULTS: The exact histopathological evaluation of early cancers of the gastrointestinal tract is of crucial importance. It is the essential basis for all further therapy decisions. In most cases, an option for a local resection is given. In comparison to partial or complete organ resections, local resection is associated with a significantly decreased morbidity and reduced length of hospital stays; however, it must be ensured that local therapies do not become responsible for increased rates of tumor recurrence and progression. Therefore, an optimal risk estimation based on a sophisticated histopathological classification is mandatory. This includes the evaluation of the infiltration depth, grading, lymphovascular invasion and resection margins. CONCLUSION: Molecular analyses have not yet entered clinical practice. The only exceptions are investigations to detect hereditary diseases. The exact histopathological diagnostic of early gastrointestinal cancers is the basis of an effective and organ-preserving therapy.

Surgical resection is the only curative treatment option. AIM OF THE STUDY: This study analyzed the prognostic factors after resection of ICC. MATERIAL AND METHODS: A total of 84 patients were surgically treated under potentially curative intent. Perihilar and distal cholangiocarcinomas were excluded. The 5-year survival was analyzed with respect to tumor stage (TNM), number of lesions, complete surgical resection (R0), peritoneal carcinosis and postoperative complications. RESULTS: The 5-year survival was 27% and 77% of patients underwent R0 resections. In the univariate analysis a T stage >2, an N+ situation or an R+ resection as well as peritoneal and multilocular intrahepatic spread were associated with a poorer prognosis. Postoperative complications also negatively influenced survival. On multivariate analysis the absence of peritoneal spread, node-negative tumor stages, singular hepatic lesions and a low T stage as well as the absence of complications were associated with improved survival. DISCUSSION: The prognosis of ICC is poor even after successful surgical resection. Well-known tumor characteristics such as TNM are relevant prognostic factors. Surgical resection is accompanied by postoperative complications (most frequently biliary), which negatively influence survival. Adjuvant strategies are urgently needed to improve long-term survival even after complete surgical resection. PMID- 29464309 TI - Nanotechnology in Plants. AB - The integration of nanotechnology in medicine has had a tremendous impact in the past few decades. The discovery of synthesis of nanomaterials (NMs) and their functions as versatile tools promoted various applications in nano-biotechnology and nanomedicine. Although the physical and chemical methods are still considered as commonly used methods, they introduce several drawbacks such as the use of toxic chemicals (solvent, reducing, and capping agents) and poor control of size, size distribution, and morphology, respectively. Additionally, the NMs synthesized in organic solvents and hydrophobic surfactants rapidly aggregate in aqueous solutions or under physiologic conditions, limiting their applications in medicine. Many of the phase-transfer strategies were developed and applied for the transfer of NMs into aqueous solutions. Although great efforts have been put into phase transfers, they mostly include expensive, time-consuming, intensive labor work, multi steps, and complicated procedures.Use of plant extracts in the biological synthesis method offers stark advantages over other biomolecules (protein, enzyme, peptide, and DNA). Plant extracts have been commonly used for food, medicine, NM synthesis, and biosensing. There are many viable techniques developed for the production of plant extracts with various contents based on their simplicity, cost, and the type of extract content. In this chapter, we conduct a comparative study for extract preparation techniques, the use of extracts for metallic single and hybrid nanoparticle (NP) synthesis, and their antimicrobial properties against pathogenic and plant-based bacteria. Graphical Abstract. PMID- 29464310 TI - Different strategies for multi-enzyme cascade reaction for chiral vic-1,2-diol production. AB - The stereoselective three-enzyme cascade for the one-pot synthesis of (1S,2S)-1 phenylpropane-1,2-diol ((1S,2S)-1-PPD) from inexpensive starting substrates, benzaldehyde and acetaldehyde, was explored. By coupling stereoselective carboligation catalyzed by benzoylformate decarboxylase (BFD), L-selective reduction of a carbonyl group with alcohol dehydrogenase from Lactobacillus brevis (ADHLb) as well as the coenzyme regeneration by formate dehydrogenase (FDH), enantiomerically pure diastereoselective 1,2-diol was produced. Two different multi-enzyme system approaches were applied: the sequential two-step one-pot and the simultaneous one-pot cascade. All enzymes were kinetically characterized. The impact of acetaldehyde on the BFD and ADHLb stability was investigated. To overcome the kinetic limitation of acetaldehyde in the carboligation reaction and to reduce its influence on the enzyme stability, experiments were performed in two different excesses of acetaldehyde (100 and 300%). Due to the ADHLb deactivation by acetaldehyde, the simultaneous one-pot cascade proved not to be the first choice for the investigated three-enzyme system. In the sequential cascade with 300% acetaldehyde excess a 100% yield of vic 1,2-diol was reached. PMID- 29464311 TI - High PD-L1 expression predicts poor prognosis in diffuse large B-cell lymphoma.

AB - Castleman's disease (CD) is a rare lymphoproliferative disorder, and its prevalence in Thailand is not known. This 10-year period study investigated the prevalence of CD in Thailand, and the clinical characteristics and outcomes of Thai CD patients, with special focus on the existence and prevalence of TAFRO syndrome. TAFRO syndrome is defined as CD with thrombocytopenia, anasarca, fever, reticulin fibrosis, and organomegaly. Thirty-three CD patients diagnosed and treated at Siriraj Hospital during January 2007 to December 2016 were included. The prevalence of CD was 1.4 per 1,000,000 patients/10 years. Median age was 46 years, with slight female predominance. Six patients were assigned to the TAFRO group. A high proportion of TAFRO syndrome (18.2%) was found among Thai adult CD patients. In addition to routine TAFRO diagnostic criteria, significantly lower hemoglobin and albumin levels were observed in the TAFRO group than in the non TAFRO group. Treatment outcomes of CD patients were complete remission (52%), stable disease (30%), and death (13%). Three-year overall survival in the non TAFRO group and TAFRO group was 88 and 50%, respectively. While most CD patients had a good prognosis, severe cases with TAFRO syndrome had poor outcome.

AB - As Cannabis sativa (marijuana) is a controlled substance in many parts of the world, the ability to track biogeographical origin of cannabis could provide law enforcement with investigative leads regarding its trade and distribution. Population substructure and inbreeding may cause cannabis plants to become more genetically related. This genetic relatedness can be helpful for intelligence purposes. Analysis of autosomal, chloroplast, and mitochondrial DNA allows for not only prediction of biogeographical origin of a plant but also discrimination between individual plants. A previously validated, 13-autosomal STR multiplex was used to genotype 510 samples. Samples were analyzed from four different sites: 21 seizures at the US-Mexico border, Northeastern Brazil, hemp seeds purchased in the US, and the Araucania area of Chile. In addition, a previously reported multi loci system was modified and optimized to genotype five chloroplast and two mitochondrial markers. For this purpose, two methods were designed: a homopolymeric STR pentaplex and a SNP triplex with one chloroplast (Cscp001) marker shared by both methods for quality control. For successful mitochondrial and chloroplast typing, a novel real-time PCR quantitation method was developed and validated to accurately estimate the quantity of the chloroplast DNA (cpDNA) using a synthetic DNA standard. Moreover, a sequenced allelic ladder was also designed for accurate genotyping of the homopolymeric STR pentaplex. For autosomal typing, 356 unique profiles were generated from the 425 samples that yielded full STR profiles and 25 identical genotypes within seizures were observed. Phylogenetic analysis and case-to-case pairwise comparisons of 21 seizures at the US-Mexico border, using the Fixation Index (F ST ) as genetic distance, revealed the genetic association of nine seizures that formed a reference population. For mitochondrial and chloroplast typing, subsampling was performed, and 134 samples were genotyped. Complete haplotypes (STRs and SNPs) were observed for 127 samples. As expected, extensive haplotype sharing was observed; five distinguishable haplotypes were detected. In the reference population, the same haplotype was observed 39 times and two unique haplotypes were also detected. Haplotype sharing was observed between the US border seizures, Brazil, and Chile, while the hemp samples generated a distinct haplotype. Phylogenetic analysis of the four populations was performed, and results revealed that both autosomal and lineage markers could discern population substructure. PMID- 29464315 TI - I don't need your attention: ostracism can narrow the cone of gaze. AB - Previous research has shown that ostracized participants seek inclusive cues, such as gaze directed at them, when trying to reaffiliate. However, instead of seeking reinclusion, ostracized individuals may sometimes withdraw from interactions if not offered an opportunity for reaffiliation. In the current study, after an ostracism manipulation with no reaffiliation opportunity, participants judged whether faces portraying direct gaze or slightly averted gaze (2 degrees -8 degrees to the left and to the right) were looking at them or not. Compared to an inclusion group and a non-social control group, ostracized participants accepted a smaller range of gaze directions as being directed at them, i.e., they had a narrower "cone of gaze". The width of the gaze cone was equally wide in the inclusion and control groups. We propose that, without an opportunity for reaffiliation, ostracized participants may start to view other people as particularly unapproachable, possibly indicative of a motivational tendency to disengage from interactions. PMID- 29464316 TI - The right look for the job: decoding cognitive processes involved in the task from spatial eye-movement patterns. AB - The aim of the study was not only to demonstrate whether eye-movement-based task decoding was possible but also to investigate whether eye-movement patterns can be used to identify cognitive processes behind the tasks. We compared eye movement patterns elicited under different task conditions, with tasks differing systematically with regard to the types of cognitive processes involved in solving them. We used four tasks, differing along two dimensions: spatial (global vs. local) processing (Navon, Cognit Psychol, 9(3):353-383 1977) and semantic (deep vs. shallow) processing (Craik and Lockhart, J Verbal Learn Verbal Behav, 11(6):671-684 1972). We used eye-movement patterns obtained from two time periods: fixation cross preceding the target stimulus and the target stimulus. We found significant effects of both spatial and semantic processing, but in case of the latter, the effect might be an artefact of insufficient task control. We found above chance task classification accuracy for both time periods: 51.4% for the period of stimulus presentation and 34.8% for the period of fixation cross presentation. Therefore, we show that task can be to some extent decoded from the preparatory eye-movements before the stimulus is displayed. This suggests that anticipatory eye-movements reflect the visual scanning strategy employed for the task at hand. Finally, this study also demonstrates that decoding is possible even from very scant eye-movement data similar to Coco and Keller, J Vis 14(3):11 11 (2014). This means that task decoding is not limited to tasks that naturally take longer to perform and yield multi-second eye-movement recordings.

AB - We examined the functional activity of peripheral blood neutrophils and the complement system activation status in patients with rheumatoid arthritis (RA) undergoing infliximab/methotrexate combined therapy. We studied female RA patients under treatment with infliximab (3-5 mg/kg) and methotrexate (15-25 mg/week) who presented inactive (i-RA; n = 34, DAS-28 <= 2.6) or at least moderately active disease (a-RA; n = 29, DAS-28 > 3.2), and age-matched healthy women (n = 38). We measured the levels of reactive oxygen species (ROS) generation (chemiluminescence assay) and membrane expression of FcgammaRIIa/CD32, FcgammaRIIIb/CD16, CR1/CD35, and CR3/CD11b receptors (ELISA assay) in neutrophils. We also determined the hemolytic activity of the alternative and classical pathways of the complement system (spectrophotometry), serum levels of C5a and Bb (ELISA assay), and serum chemotactic activity (Boyden chamber). Compared with the control group, i-RA and a-RA patients exhibited: (1) increased neutrophil ROS production and membrane expression of FcgammaRIIa/CD32, FcgammaRIIIb/CD16, and CR1/CD35, indicating neutrophil activation; and (2) increased serum chemotactic activity and decreased activity of the alternative complement pathway, indicating systemic complement system activation. The levels of C-reactive protein in a-RA patients were augmented, compared with i-RA patients. Although infliximab/methotrexate combined therapy induced disease remission according to the DAS-28 criteria, both i-RA and a-RA patients still exhibited significant levels of systemic activation of neutrophils and the complement system. PMID- 29464318 TI - Diffusion MRI-based cortical connectome reconstruction: dependency on tractography procedures and neuroanatomical characteristics. AB - Diffusion MRI (dMRI)-based tractography offers unique abilities to map whole brain structural connections in human and animal brains. However, dMRI-based tractography indirectly measures white matter tracts, with suboptimal accuracy and reliability. Recently, sophisticated methods including constrained spherical deconvolution (CSD) and global tractography have been developed to improve tract reconstructions through modeling of more complex fiber orientations. Our study aimed to determine the accuracy of connectome reconstruction for three dMRI-based tractography approaches: diffusion tensor (DT)-based, CSD-based and global tractography. Therefore, we validated whole brain structural connectome reconstructions based on ten ultrahigh-resolution dMRI rat brain scans and 106 cortical regions, from which varying tractography parameters were compared against standardized neuronal tracer data. All tested tractography methods generated considerable numbers of false positive and false negative connections. There was a parameter range trade-off between sensitivity: 0.06-0.63 interhemispherically and 0.22-0.86 intrahemispherically; and specificity: 0.99 0.60 interhemispherically and 0.99-0.23 intrahemispherically. Furthermore, performance of all tractography methods decreased with increasing spatial distance between connected regions. Similar patterns and trade-offs were found, when we applied spherical deconvolution informed filtering of tractograms, streamline thresholding and group-based average network thresholding. Despite the potential of CSD-based and global tractography to handle complex fiber orientations at voxel level, reconstruction accuracy, especially for long distance connections, remains a challenge. Hence, connectome reconstruction benefits from varying parameter settings and combination of tractography methods to account for anatomical variation of neuronal pathways. PMID- 29464319 TI - Involvement of CAT in the detoxification of HT-induced ROS burst in rice anther and its relation to pollen fertility. AB - KEY MESSAGE: HT-induced ROS burst in developing anther is closely related to the lowered CAT activity as the result of the markedly suppressed OsCATB transcript, thereby causing severe fertility injury for rice plants exposed to HT at meiosis stage. The reproductive stage of rice plants is highly sensitive to heat stress. In this paper, different rice cultivars were used to investigate the relationship of HT-induced floret sterility with reactive oxygen species (ROS) detoxification in rice anthers under well-controlled climatic conditions. Results showed that high temperature (HT) exposure significantly enhanced the ROS level and malondialdehyde (MDA) content in developing anther, and the increase in ROS amount in rice anther under HT exposure was closely associated with HT-induced decline in the activities of several antioxidant enzymes. For various antioxidant enzymes, SOD and CAT were more susceptible to the ROS burst in rice anther induced by HT exposure than APX and POD, in which SOD and CAT activity in developing anther decreased significantly by HT exposure, whereas APX activity was relatively stable among different temperature regimes. HT-induced decrease in CAT activity was attributable to the suppressed transcript of OsCATB. This occurrence was strongly responsible for HT-induced increase in ROS level and oxidative-damage in rice anther, thereby it finally caused significant reduction in pollen viability and floret fertility for the rice plants exposed to HT during meiosis. Exogenous application of 1000 uM salicylic acid (SA) may alleviate HT induced reduction in pollen viability and floret fertility, concomitantly with the increased CAT activity and reduced ROS level in rice anther. PMID- 29464320 TI - Comparative immunohistochemical characterization of interstitial cells in the urinary bladder of human, guinea pig and pig. AB - Interstitial cells (ICs) are thought to play a functional role in urinary bladder. Animal models are commonly used to elucidate bladder physiology and pathophysiology. However, inter-species comparative studies on ICs are rare. We therefore analyzed ICs and their distribution in the upper lamina propria (ULP), the deeper lamina propria (DLP) and the detrusor muscular layer (DET) of human, guinea pig (GP) and pig. Paraffin slices were examined by immunohistochemistry and 3D confocal immunofluorescence of the mesenchymal intermediate filament vimentin (VIM), alpha-smooth muscle actin (alphaSMA), platelet-derived growth factor receptor alpha (PDGFRalpha) and transient receptor potential cation channel A1 (TRPA1). Image stacks were processed for analysis using Huygens software; quantitative analysis was performed with Fiji macros. ICs were identified by immunoreactivity for VIM (excluding blood vessels). In all species >= 75% of ULP ICs were VIM+/PDGFRalpha+ and >= 90% were VIM+/TRPA1+. In human and pig >= 74% of ULP ICs were VIM+/alphaSMA+, while in GP the percentage differed significantly with only 37% VIM+/alphaSMA+ ICs. Additionally, over 90% of alphaSMA+ ICs were also TRPA1+ and PDGFRalpha+ in human, GP and pig. In all three species, TRPA1+ and PDGFRalpha+ ICs point to an active role for these cells in bladder physiology, regarding afferent signaling processes and signal modification. We hypothesize that decline in alphaSMA-positivity in GP reflects adaptation of bladder histology to smaller bladder size. In our experiments, pig bladder proved to be highly comparable to human urinary bladder and seems to provide safer interpretation of experimental findings than GP. PMID- 29464321 TI - Origin and development of septoclasts in endochondral ossification of mice. AB - Septoclasts are mononuclear spindle-shaped phagocytes with their long processes in uncalcified cartilage matrices and locate adjacent to the capillary endothelium at the chondro-osseous junction of the growth plate. We have previously revealed a selective expression of epidermal-type fatty acid-binding protein (E-FABP/FABP5) in septoclasts. Although, pericytes are known to distribute along capillaries and directly surround their endothelial cells in a situation similar to septoclasts, no clear evidence is available on the relationship between septoclasts and pericytes. We investigated the chronological localization and morphological change of septoclasts during development of the tibia of mice to clarify the development of septoclasts and the immune localization of pericyte markers in septoclasts to clarify the origin of septoclasts. E-FABP-immunoreactive septoclasts emerged at the perichondrium in the middle of the cartilaginous templates of the tibia in prenatal development. Septoclasts migrated to the surface of the cartilage adjacent to invading blood vessels. Processes of septoclasts became longer and their apexes attached to Von Kossa-negative uncalcified matrices during the formation process of the primary ossification center. Not only platelet-derived growth factor receptor beta, but also neuron-glial antigen 2 was localized in septoclasts of mice from E15 (embryonic day 15) to P6w (postnatal 6 week). Our results suggest that septoclasts are originated from pericytes and involved in the blood vessel invasion during formation of the primary ossification center. PMID- 29464323 TI - Vermetid gastropods modify physical and chemical conditions above coral-algal interactions. AB - Interaction modifications can arise when a third species alters the physical and chemical environment within which two other species interact. On coral reefs, corals and algae commonly interact amid a suite of other species that may modify their interaction. Massive Porites coral and algal turfs often are covered by mucus nets cast by the vermetid gastropod, Ceraesignum maximum. Previously, vermetid mucus nets have been shown to have deleterious effects on corals. Here, we hypothesized that vermetids not only have direct effects on coral, but they also change the local physical and chemical environment establishing the potential for interaction modifications by intensifying the effects of algae on corals. To test this, we examined the effect of vermetids on physical and chemical aspects of the environments. We quantified light penetration, water flow, diffusive boundary layer (DBL) thickness, and oxygen concentrations in the presence and absence of vermetid nets. Vermetid nets did not affect light levels. Because we observed reduced water flow and increased DBL thickness in the presence of nets, we also expected to observe high oxygen concentration over coral surfaces. Instead, we observed no difference in oxygen concentrations in the presence of mucus nets. To explain the lower than expected oxygen concentrations, we hypothesize that nets decreased photosynthesis and/or increased respiration of corals and algae and their associated microbiota. This is the first study to explore mechanisms underlying the deleterious effects of vermetids on corals, and shows that vermetid mucus nets may modify coral-algal interactions by intensifying physical and chemical conditions. PMID- 29464322 TI - Voltinism-associated differences in winter survival across latitudes: integrating growth, physiology, and food intake. AB - Species that span large latitudinal gradients face strong differences in voltinism and in winter conditions within their range. Latitudinal gradients in winter survival and especially their underlying mechanisms and association with voltinism patterns are poorly studied. We tested in the damselfly Enallagma cyathigerum whether high-latitude populations were better in dealing with the longer winters compared to central- and low-latitude populations and whether this was associated with changes in voltinism. We thereby evaluated whether higher initial levels and/or lower reductions during winter of energy storage (measured as fat content) and investment in immune function [measured as the activity of phenoloxidase (PO)], and/or stronger compensatory responses in food intake contributed to the higher winter survival in high-latitude populations. To this end, we simulated a long high-latitude winter at 4 degrees C under manipulated food conditions. Across food levels, winter survival was highest in Swedish larvae, intermediate in Belgian larvae, and lowest in Spanish larvae, indicating latitude-specific thermal adaptation that could be partly linked to differences in voltinism. The semi-voltine Swedish larvae were growing slower before winter and as a result accumulated the highest fat content and PO activity when the winter started compared to the univoltine, faster growing Belgian, and Spanish larvae. Fat content and PO activity declined during the winter, yet equally across latitudes, and were not buffered by compensatory food intake. Our data identified possible underlying physiological mechanisms of winter survival and support the hypothesis that widespread latitude-associated voltinism shifts may be a selective factor contributing to latitudinal shifts in winter survival.

AB - Improving the yield of carbohydrate to lipid conversion and lipid productivity are two critical goals to develop an economically feasible process to commercialize microbial oils. Lignocellulosic sugars are potential low-cost carbon sources for this process but their use is limited by the toxic compounds produced during biomass pretreatment at high solids loading, and by the pentose sugars (mainly xylose) which are not efficiently metabolized by many microorganisms. Adaptive laboratory evolution was used to select a Rhodosporidium toruloides strain with robust growth in non-detoxified wheat straw hydrolysates, produced at 20% solids loading, and better xylose consumption rate. An arabinose inducible cre-lox recombination system was developed in this evolved strain that was further engineered to express a second copy of the native DGAT1 and SCD1 genes under control of the native xylose reductase (XYL1) promoter. Fed-batch cultivation of the engineered strain in 7-L bioreactors produced 39.5 g lipid/L at a rate of 0.334 g/Lh-1 and 0.179 g/g yield, the best results reported in R. toruloides with non-detoxified lignocellulosic hydrolysates to date. PMID- 29464325 TI - Detection and cell sorting of Pseudonocardia species by fluorescence in situ hybridization and flow cytometry using 16S rRNA-targeted oligonucleotide probes. AB - Pseudonocardia spp. are receiving increasing attention due to their ability to biodegrade recalcitrant cyclic ether pollutants (e.g., 1,4-dioxane and tetrahydrofuran), as well as for their distinctive ecological niches (e.g., symbiosis with ants/plants and production of antibiotics). Isolating and characterizing Pseudonocardia spp. is thus important to discern their metabolic and physiological idiosyncrasies and advance their potential applications. However, slow growth, low cell yield, and dissimilar colony morphology hinder efficient isolation of Pseudonocardia using conventional plating methods. Here, we develop the first fluorescent probe (Pse631) targeting the 16S rRNA of Pseudonocardia members. In combination with flow cytometry and cell sorting, in situ hybridization with this probe enables sensitive and specific detection of Pseudonocardia cells in mixed cultures and enriched environmental samples without significant false positives, using Escherichia coli, Bacillus subtilis, and Mycobacterium spp. as negative controls. Pseudonocardia dioxanivorans CB1190 cells labeled with Pse631 as a positive control were detected when their relative abundance in the total bacterial community was as low as 0.1%. Effective separation of Pseudonocardia cells from the mixed consortium was confirmed by quantitative PCR analysis of sorted cells. This study provides a culture independent high-throughput molecular approach enabling effective separation of Pseudonocardia populations from complex microbial communities. This approach will not only facilitate subsequent molecular analyses including species identification and quantification, but also advance understanding of their catabolic capacities and functional molecular diversity. PMID- 29464326 TI - Furfural-tolerant Zymomonas mobilis derived from error-prone PCR-based whole genome shuffling and their tolerant mechanism. AB - Furfural-tolerant strain is essential for the fermentative production of biofuels or chemicals from lignocellulosic biomass. In this study, Zymomonas mobilis CP4 was for the first time subjected to error-prone PCR-based whole genome shuffling, and the resulting mutants F211 and F27 that could tolerate 3 g/L furfural were obtained. The mutant F211 under various furfural stress conditions could rapidly grow when the furfural concentration reduced to 1 g/L. Meanwhile, the two mutants also showed higher tolerance to high concentration of glucose than the control strain CP4. Genome resequencing revealed that the F211 and F27 had 12 and 13 single-nucleotide polymorphisms. The activity assay demonstrated that the activity of NADH-dependent furfural reductase in mutant F211 and CP4 was all increased under furfural stress, and the activity peaked earlier in mutant than in control. Also, furfural level in the culture of F211 was also more rapidly decreased. These indicate that the increase in furfural tolerance of the mutants may be resulted from the enhanced NADH-dependent furfural reductase activity during early log phase, which could lead to an accelerated furfural detoxification process in mutants. In all, we obtained Z. mobilis mutants with enhanced furfural and high concentration of glucose tolerance, and provided valuable clues for the mechanism of furfural tolerance and strain development.

PMID- 29464327 TI - Unclassified sclerosing malignant melanomas with AKAP9-BRAF gene fusion: a report of two cases and review of BRAF fusions in melanocytic tumors. AB - The current classification of melanocytic tumors includes clinical, pathological, and molecular data. A subset of lesions remains difficult to classify according to these complex multilayer schemes. We report two cases of deeply infiltrating melanomas with a sclerosing background. The first case occurred on the back of a middle-aged man appearing clinically as a dermatofibroma. The architectural and cytological aspects resembled those of a desmoplastic melanoma but the strong expression of both melanA and HMB45, two stainings usually reported as negative in this entity, raised the question of an alternate diagnosis. The second case was a large, slowly growing, perivulvar tumor in a middle-aged woman. The morphology was complex with a central junctional spitzoid pattern associating an epidermal hyperplasia with large nests of large spindled melanocytes. The dermal component was made of deeply invasive strands and nests of nevoid unpigmented melanocytes surrounded by fibrosis; a perineural invasion was present at the periphery of the lesion. In both cases, aCGH found, among many other anomalies, a chromosomal breakpoint at the BRAF locus. RNA sequencing identified in both an AKAP9-BRAF gene fusion. A complementary resection was performed and no relapses have been observed in the respectively 15 and 6 months of follow-up. Both of these melanomas remained unclassified. We further review the variety of melanocytic tumors associated with such BRAF fusions. PMID- 29464329 TI - [Systematic literature search in PubMed : A short introduction]. AB - In order to identify current (and relevant) evidence for a specific clinical question within the unmanageable amount of information available, solid skills in performing a systematic literature search are essential. An efficient approach is to search a biomedical database containing relevant literature citations of study reports. The best known database is MEDLINE, which is searchable for free via the PubMed interface. In this article, we explain step by step how to perform a systematic literature search via PubMed by means of an example research question in the field of ophthalmology. First, we demonstrate how to translate the clinical problem into a well-framed and searchable research question, how to identify relevant search terms and how to conduct a text word search and a search with keywords in medical subject headings (MeSH) terms. We then show how to limit the number of search results if the search yields too many irrelevant hits and how to increase the number in the case of too few citations. Finally, we summarize all essential principles that guide a literature search via PubMed. PMID- 29464330 TI - The interplay of histone H2B ubiquitination with budding and fission yeast heterochromatin. AB - Mono-ubiquitinated histone H2B (H2B-Ub) is important for chromatin regulation of transcription, chromatin assembly, and also influences heterochromatin. In this review, we discuss the effects of H2B-Ub from nucleosome to higher-order chromatin structure. We then assess what is currently known of the role of H2B-Ub in heterochromatic silencing in budding and fission yeasts (S. cerevisiae and S. pombe), which have distinct silencing mechanisms. In budding yeast, the SIR complex initiates heterochromatin assembly with the aid of a H2B-Ub deubiquitinase, Ubp10. In fission yeast, the RNAi-dependent pathway initiates heterochromatin in the context of low H2B-Ub. We examine how the different silencing machineries overcome the challenge of H2B-Ub chromatin and highlight the importance of using these microorganisms to further our understanding of H2B Ub in heterochromatic silencing pathways. PMID- 29464331 TI - Salvage proton beam therapy for recurrent iris melanoma: outcome and side effects. AB - PURPOSE: This study aims to analyze the effect of salvage proton beam therapy for the treatment of recurrent iris melanoma. METHOD: In this clinical case series, we retrospectively analyzed the data of eight patients who underwent proton beam therapy of the whole anterior segment as salvage therapy between 2000 and 2016 for recurrent iris melanoma after resection, ruthenium brachytherapy, or sector proton beam therapy. Two patients received salvage proton beam therapy for repeated tumor relapse. All patients were observed and prepared for proton beam therapy at the Charite and irradiated at the Helmholtz-Zentrum Berlin where they received 50 cobalt Gray equivalents (CGE) in four daily fractions. We investigated survival rates and ocular outcome. RESULTS: Median follow-up after salvage proton beam therapy was 39 months. No local recurrence was detected during follow-up. One patient died from hepatic metastases 5.5 years after salvage therapy. Secondary glaucoma occurred in seven out of eight patients during follow-up. Two patients had chronic corneal erosion and two other patients presented with corneal decompensation, necessitating Descemet membrane endothelial keratoplasty (DMEK), and perforating keratoplasty. Median visual acuity was 0.2 logMAR before salvage proton beam therapy and 0.7 logMAR at the end of follow-up. CONCLUSION: Whole anterior segment salvage proton beam therapy has effectively controlled recurrent iris melanoma in our patients, but has been associated with a high incidence of radiation-induced corneal impairment and secondary glaucoma requiring extensive secondary treatment. PMID- 29464332 TI - The effect of sevoflurane on retinal angiogenesis in a mouse model of oxygen induced retinopathy. AB - BACKGROUND: Sevoflurane is commonly used in general anesthesia for premature neonates. The main mechanism of retinopathy of prematurity (ROP) is increased levels of vascular endothelial growth factor (VEGF). For the investigation of sevoflurane's effect on angiogenesis, the angiogenesis and VEGF expression in the retina were measured after administering sevoflurane in an oxygen-induced retinopathy mice model. MATERIALS AND METHODS: The mice were divided into the normoxic group (Nc and Ns group; n = 6) and the ROP group (C, Rc, and Rs group; n = 6). Rc group were exposed to 75% oxygen for 5 days beginning on postnatal day (P) 7, and then returned to room air. Age-matched mice in the C group were exposed to room air. To observe angiogenesis of the retina, the mice were sacrificed on P16. The Rs group was exposed to 2 vol% sevoflurane for 2 h on P12, P13, and P14 with 40% oxygen. RESULTS: The angiogenic area and the spreading distance of vessels on P4 were statistically decreased in the Ns group, compared to the Nc group. The avascular area on P16 was significantly increased and the expression of VEGF was suppressed in the Rs group compared to the Rc group. CONCLUSIONS: Sevoflurane can inhibit retinal angiogenesis via suppressing VEGF expression in an OIR mice model with exposure to relative hypoxia. Nevertheless, it is still difficult to apply the results of this study immediately to humans because of the heterogeneity of responses to sevoflurane.

AB - The mechanisms for the acetylene hydrochlorination reaction on pristine Au7 and Au8 clusters and on the Si-doped Au clusters Au6Si and Au7Si were systematically investigated via density functional theory using the PBE functional. The band gap (?Eg) of the Au7Si cluster was found to smaller than that of its undoped equivalent (Au8), thus enhancing its catalytic activity, and Au7Si presented a significantly reduced activation barrier (16.69 kcal mol-1) for the acetylene hydrochlorination reaction compared with the pristine Au8 cluster (21.83 kcal mol 1). On the other hand, the activation barrier for the acetylene hydrochlorination reaction was not lower for the Au6Si cluster than for the pristine Au7 cluster because the band gap (?Eg) of Au6Si was found to be larger than that of Au7. Hence, the current work shows that the catalytic activities of gold clusters can be systematically modified by doping them. Our findings also suggest how to enhance the acetylene hydrochlorination reaction by doping foreign atoms into Au clusters. Graphical abstract The Si-doped Au7Si cluster showed stronger catalytic activity for the acetylene hydrochlorination reaction compared with the pristine Au8 cluster.

AB - Electrical charge transport through thiophene-dithiol-based molecular wires attached to gold electrodes with three different types of crystallographic orientations (<1,1,1>, <1,1,0 > and <1,0,1 >) was investigated. Electron transport in the systems under consideration was evaluated systematically by analyzing current values, transmission spectrum, projected device density of states and zero bias orbital analysis utilizing density functional theory in conjunction with non-equilibrium Green's function. Investigations proved that tuning of conductance in nano-molecular junctions is possible through different electrode orientations. As the HOMO-LUMO gap in the <1,1,0 > oriented thiophene dithiol junction is drastically less than that of the other configurations under consideration, the <1,1,0 > configuration exhibited superior constructive conductance in comparison to other junction orientations. This provided us with ideas for designing pioneering hetero-cyclic nano-scale electronics devices. Also, <1,1,0 > has been found to show negative differential conductance behavior above +2.6 V and below -2.6 V, and hence has potential applications in oscillating and switching circuits.

AB - In this work we investigate the level of theory necessary for reproducing the non linear variation of the 129Xe nuclear magnetic resonance (NMR) chemical shift with the density of Xe in supercritical conditions. In detail we study how the 129Xe chemical shift depends under supercritical conditions on electron correlation, relativistic and many-body effects. The latter are included using a sequential-QM/MM methodology, in which a classical MD simulation is performed first and the chemical shift is then obtained as an average of quantum calculations of 250 MD snapshots conformations carried out for Xe n clusters (n = 2 - 8 depending on the density). The analysis of the relativistic effects is made at the level of 4-component Hartree-Fock calculations (4c-HF) and electron correlation effects are considered using second order Moller-Plesset perturbation theory (MP2). To simplify the calculations of the relativistic and electron correlation effects we adopted an additive scheme, where the calculations on the Xe n clusters are carried out at the non-relativistic Hartree-Fock (HF) level, while electron correlation and relativistic corrections are added for all the pairs of Xe atoms in the clusters. Using this approach we obtain very good agreement with the experimental data, showing that the chemical shift of 129Xe in supercritical conditions is very well described by cluster calculations at the HF level, with small contributions from relativistic and electron correlation effects.

AB - Joint pain attributable to osteoarthritis (OA) is complex and influenced by a myriad of factors beyond local joint pathology. Current practice continues to predominantly adopt a biomedical approach to OA despite emerging evidence of the importance of a more holistic approach. This paper will summarise evidence for the presence of multidimensional pain profiles in knee joint pain and the presence of subgroups characterized by systemic features such as psychological distress, high comorbidity load or sensitisation of the nervous system. These factors have the potential to influence patient outcomes making them relevant for clinicians and highlighting the necessity of a broader multifactorial approach to assessment and treatment. This review describes the current state of the evidence for treatments of people with knee OA-related pain, including those receiving strong recommendations from current clinical guidelines, namely exercise, weight loss, self-management advice and pharmacological approaches. Other pain modulating treatment options are emerging such as sleep and psychological interventions, pain education and multisensory retraining. The evidence and rationale for these newer therapeutic approaches is discussed. Finally, this review will highlight some of the limitations of current international guidelines for the management of OA and make recommendations for future research. PMID- 29464337 TI - Health risk assessment on human exposed to heavy metals in the ambient air PM10 in Ahvaz, southwest Iran. AB - Heavy metals (HM) are one of the main components of urban air pollution. Today, megacities and industrial regions in southwest of Iran are frequently suffering from severe haze episodes, which essentially caused by PM10-bound heavy metals. The purpose of this study was to evaluate the health risk assessment on human exposed to heavy metals (Cr, Ni, Pb, and Zn) in the ambient air PM10 in Ahvaz, southwest Iran. In this study, we estimated healthy people from the following scenarios: (S3) residential site; (S2) high-traffic site; (S1) industrial site in Ahvaz metropolitan during autumn and winter. In the current study, high-volume air samplers equipped with quartz fiber filters were used to sampling and measurements of heavy metal concentration. Inductively coupled plasma optical emission spectroscopy (ICP-OES) was utilized for detection of heavy metal concentration (ng m-3). Also, an estimate of the amount of health risk assessment (hazard index) of Cr, Ni, Pb, and Zn of heavy metal exposure to participants was used. Result of this study showed that the residential and industrial areas had the lowest and the highest level of heavy metal. Based on the result of this study, average levels of heavy metal in industrial, high-traffic, and residential areas in autumn and winter were 31.48, 30.89, and 23.21 MUg m-3 and 42.60, 37.70, and 40.07 MUg m-3, respectively. Based on the result of this study, the highest and the lowest concentration of heavy metal had in the industrial and residential areas. Zn and Pb were the most abundant elements among the studied PM10-bound heavy metals, followed by Cr and Ni. The carcinogenic risks of Cr, Pb, and the integral HQ of metals in PM10 for children and adults via inhalation and dermal exposures exceeded 1 * 10-4 in three areas. Also, based on the result of this study, the values of hazard index (HI) of HM exposure in different areas were significantly higher than standard. The health risks attributed to HM should be further investigated from the perspective of the public health in metropolitans. The result of this study showed increasing exposure concentrations to heavy metal in the studied scenarios have a significant potential for generating different health endpoints, while environmental health management in ambient air can cause disorders in citizenship and causing more spiritual and material costs.

PMID- 29464339 TI - New GJA8 variants and phenotypes highlight its critical role in a broad spectrum of eye anomalies. AB - GJA8 encodes connexin 50 (Cx50), a transmembrane protein involved in the formation of lens gap junctions. GJA8 mutations have been linked to early onset cataracts in humans and animal models. In mice, missense mutations and homozygous Gja8 deletions lead to smaller lenses and microphthalmia in addition to cataract, suggesting that Gja8 may play a role in both lens development and ocular growth. Following screening of GJA8 in a cohort of 426 individuals with severe congenital eye anomalies, primarily anophthalmia, microphthalmia and coloboma, we identified four known [p.(Thr39Arg), p.(Trp45Leu), p.(Asp51Asn), and p.(Gly94Arg)] and two novel [p.(Phe70Leu) and p.(Val97Gly)] likely pathogenic variants in seven families. Five of these co-segregated with cataracts and microphthalmia, whereas the variant p.(Gly94Arg) was identified in an individual with congenital aphakia, sclerocornea, microphthalmia and coloboma. Four missense variants of unknown or unlikely clinical significance were also identified. Furthermore, the screening of GJA8 structural variants in a subgroup of 188 individuals identified heterozygous 1q21 microdeletions in five families with coloboma and other ocular and/or extraocular findings. However, the exact genotype-phenotype correlation of these structural variants remains to be established. Our data expand the spectrum of GJA8 variants and associated phenotypes, confirming the importance of this gene in early eye development.

PMID- 29464341 TI - Additional cryoapplications at the pulmonary vein antrum using a 28-mm second generation cryoballoon: a pilot study of extra-pulmonary vein ablation. AB - Isolation areas post-28-mm cryoballoon pulmonary vein isolation (CB-PVI) are smaller than post-radiofrequency PV antrum isolation at the left superior PV (LSPV) antrum and recurrent atrial fibrillation (AF) can originate from this area. This pilot study evaluated the impact of additional extra-PV CB applications at the LSPV antrum following conventional CB-PVI. Eighteen paroxysmal AF patients underwent CB-PVI with single 3-min freeze techniques. Following the CB-PVI, 2-min CB applications were added once or twice at the LSPV antrum. Before and after extra-PV ablation, left atrial (LA) 3-D electroanatomical maps were created. Seventy-two total PVs were successfully isolated with 4.2 +/- 0.4 applications/patient with 28-mm CBs. The mean LA posterior wall (LAPW) and non-isolated LAPW areas were 14.9 +/- 3.6 and 6.9 +/- 2.8 cm2, respectively. After 1.6 +/- 0.5 mean extra-PV applications, the upper non-isolated LAPW area significantly decreased from 3.3 +/- 1.8 to 2.5 +/- 1.8 cm2 (p < 0.001). The lowest esophageal temperatures during the extra-PV ablation were 27 degrees C. The total procedure and fluoroscopic times were 72.8 +/- 13.1 and 15.2 +/- 5.9 min, respectively. Silent gastric hypomotility was detected in 2/9 patients 1 day later, and mild PV stenosis was observed in 4/72 PVs 3 months later, but did not progress. At 12-month after single procedures, 16 (88.9%) patients were free from recurrent AF off antiarrhythmic drugs. A median of 8.0 [6.0-10.0] months later, PV reconnections were detected in 3/12 (25.0%) PVs. The non-isolated LAPW area was significantly larger in the chronic than acute phase (14.3 +/- 5.2 cm2, p = 0.016). This pilot study suggested the potential feasibility of additional LSPV antral cryoapplications following a conventional CB-PVI. The strategy warrants further study in more patients. PMID- 29464342 TI - Vascular response to biolimus A-9 eluting stent in patients with shorter and prolonged dual antiplatelet therapy: optical coherence tomography sub-study of the NIPPON trial. AB - Dual antiplatelet therapy (DAPT) with thienopyridine and aspirin is the standard care for the prevention of stent thrombosis. However, the optimal duration and effect of the duration of DAPT on intra-stent thrombus (IS-Th) formation are unknown. The NIPPON study (Nobori Dual Antiplatelet Therapy as Appropriate Duration) was an open label, randomized multicenter, assessor-blinded, trial designed to demonstrate the non-inferiority of shorter (6-month) DAPT to prolonged (18-month) DAPT, after biolimus A9 eluting stent implantation in 3773 patients at 130 sites in Japan. Among them, 101 patients were randomly allocated for an optical coherence tomography (OCT) sub-study to assess the difference of local IS-Th formation between the two groups. In addition to standard OCT parameters, the number of IS-Th formed was counted in each target stent at 8 months. Baseline patient characteristics were not different between the 6- and 18 month groups. IS-Th was detected in 9.8% of the cases and the presence of IS-Th was not significantly different between the two groups (10.9% in 6-month vs. 9.1% in 12-month, P = 0.76). Furthermore, the number of IS-Th formed was not significantly different between the two groups. This OCT sub-study was in line with the main NIPPON study which demonstrated the non-inferiority of 6-month DAPT to 18-month DAPT. Shorter DAPT duration did not promote progressive IS-Th formation at the mid-term time point. PMID- 29464343 TI - Prognostic Significance of Platelet-Based Inflammatory Indicators in Patients with Gastric Cancer. AB - BACKGROUND: Thrombocytosis develops in association with malignant tumors and may reflect the inflammation status in cancer patients. This study retrospectively investigated the prognostic significance of two platelet-based inflammatory indicators, the platelet * C-reactive protein multiplier value (P-CRP), and platelet-lymphocyte ratio (PLR), in gastric cancer patients. METHODS: The 453 enrolled patients had a histopathological diagnosis of gastric adenocarcinoma and underwent curative surgery. RESULTS: P-CRP correlated significantly with age, tumor size, depth of invasion, lymph node metastasis, and disease stage. A high PLR correlated significantly with tumor size, depth of invasion, lymph node metastasis, lymphatic involvement, venous involvement, and disease stage. In the ROC analysis, the optimal cutoff value of P-CRP and PLR was 3.689 and 173.3, respectively. Five-year survival rates were 62.9 and 82.1% in patients with P CRPHigh (>=3.689) and P-CRPLow (<3.698), respectively (P < 0.0001). Five-year survival rates were 66.3 and 81.3% in patients with PLRHigh (>=173.3) and PLRLow (<173.3), respectively (P = 0.0022). The prognosis of the P-CRPHigh/PLRHigh group was significantly worse than that of the P-CRPHigh or PLRHigh and P-CRPLow/PLRLow groups in terms of overall survival (P < 0.0001) and disease-specific survival (P = 0.029). In a multivariate analysis, the combination of P-CRP and PLR was an independent prognostic indicator. CONCLUSIONS: The combination of P-CRP and PLR may be useful in predicting prognosis in gastric cancer patients. PMID- 29464344 TI - A Novel Classification and Staged Approach for Dissection Along the Celiac and Hepatic Artery During Pancreaticoduodenectomy. AB - BACKGROUND: In recent decades, there have been enthusiastic discussions of, and active proposals for, new approaches to dissection around the superior mesenteric artery during pancreaticoduodenectomy (PD). In contrast, dissection along the celiac axis (CA) and hepatic artery (HA) and in the hepatoduodenal ligament has rarely been systematically discussed. In this report, we propose and describe a three-level classification of dissection along the CA-HA system which is applicable to a variety of diseases for which PD is indicated. METHODS: The extent of dissection is classified into three levels. With the first level (LV 1), neither LN nor plexus dissection is required. The second level (LV-2) includes en bloc resection of LNs along the CA, HA, and in the hepatoduodenal ligament, preserving the nerve plexus around the artery. The third level (LV-3) includes en bloc dissection of LNs and the nerve plexus close to cancer invasion, for example, being accompanied by half circumferential dissection of the nerve plexus around the CA or circumferential dissection of that of HA. LV-1 dissection is indicated for benign lesions, low grade malignancy, pancreatic metastasis, or intraductal papillary mucinous neoplasm. LV-2 is indicated for periampullary malignancies requiring dissection of regional LNs, including ampullary, distal bile duct, duodenal cancers, and pancreatic cancers without evidence of invasion around the CA-HA system. LV-3 is indicated for malignancies with evidence of perineural invasion in the CA-HA system, such as pancreatic cancer at the pancreatic neck or advanced bile duct cancer. CONCLUSIONS: In combination with classified superior mesenteric artery dissection, a variety of PD procedures would be systematically classified, understood, and reproduced regardless of nature of disease, surgeon, or approach. PMID- 29464345 TI - Prognostic Impact of Bacterobilia on Morbidity and Postoperative Management After Pancreatoduodenectomy: A Systematic Review and Meta-analysis. AB - BACKGROUND: Intraoperative bile analysis during pancreatoduodenectomy (PD) is performed routinely at specialized centers worldwide. However, it remains controversial if and how intraoperative bacterobilia during PD affects morbidity and its management. The aim of the study was a systematic review and meta analysis of intraoperative bacterobilia and its impact on patient outcome after PD. METHODS: Five relevant outcomes of interest were defined, and a systematic review of the literature with meta-analysis was performed according to the PRISMA guidelines. RESULTS: A total of 28 studies (8523 patients) were included. The median incidence of bacterobilia was 58% (interquartile range 51-67%). The most frequently isolated bacteria were Enterococcus species (51%), Klebsiella species (28%), and Escherichia coli (27%). Preoperative biliary drainage was significantly associated with bacterobilia (86 vs. 25%; RR 3.27; 95% confidence interval (CI) 2.42-4.42; p < 0.001). The incidence of surgical site infections (SSI) was significantly increased in cases with bacterobilia (RR 2.84; 95% CI 2.17-3.73; p < 0.001). Postoperative pancreatic fistula, overall postoperative morbidity, and mortality were not significantly influenced. Identical bacteria in bile and the infectious sources were found in 48% (interquartile range 34-59%) of the cases. CONCLUSIONS: Bacterobilia is detected during almost every second PD and is associated with an increased rate of SSI. The microbiome from intraoperative bile and postoperative infectious sources match in ~50% of patients, providing the option of early administration of calculated antibiotics and the determination of resistance patterns. PMID- 29464347 TI - Dietary carbohydrate rather than protein intake drives colonic microbial fermentation during weight loss. AB - PURPOSE: High protein weight loss diets are effective in aiding body weight management. However, high protein and low carbohydrate intakes can alter colonic fermentation profiles in humans and may impact on colonic health. This study aims to identify the most important dietary contributors to colonic fermentation during diet-controlled weight loss. METHODS: Overweight or obese male volunteers (n = 18) consumed a body weight maintenance diet (fed at 1.5* basic metabolic rate, BMR) followed by three weight loss diets (fed at 1* BMR) for 10 days each in a cross-over design. Weight loss diets were designed as normal protein (NPWL, 15% of energy from protein, 55% from carbohydrate), normal protein enriched with free amino acids and moderate amounts of carbohydrate (NPAAWL, 15% of energy from protein, 15% from free AA, 40% from carbohydrate) or high protein containing moderate amounts of carbohydrate (HPWL, 30% of energy from protein, 40% from carbohydrate). Faecal samples collected at the end of each diet period were profiled for dietary metabolites using LC-MS/MS. RESULTS: This study shows that the NPWL diet only induced very minor changes in the faecal metabolome, whereas NPAAWL and HPWL diets decreased carbohydrate-related metabolites (butyrate, ferulic acid) and increased protein-related metabolites. Most faecal metabolites were correlated with dietary carbohydrate and not protein intake. CONCLUSION: This study demonstrates that dietary carbohydrate is the main driver of colonic fermentation in humans and that a balance between dietary carbohydrate and protein should be maintained when designing safe, effective and healthy weight loss diets. PMID- 29464346 TI - Systematic Review and Meta-analysis of Restrictive Perioperative Fluid Management in Pancreaticoduodenectomy. AB - BACKGROUND: There is significant interest and controversy surrounding the effect of restrictive fluid management on outcomes in major gastrointestinal surgery. This has been most studied in colorectal surgery, although the literature relating to pancreaticoduodenectomy (PD) patients is growing. The aim of this paper was to generate a comprehensive review of the available evidence for restrictive perioperative fluid management strategies and outcomes in PD. METHODS: MEDLINE/PubMed, Embase, and the Cochrane Library were searched from inception to April 2017. A review protocol was utilized and registered with PROSPERO. Primary citations that evaluated perioperative fluid management in PD, including those as part of a clinical pathway, were considered. The primary outcome was postoperative pancreatic fistula (POPF). Secondary outcomes included delayed gastric emptying (DGE), complication rate, length of stay (LOS), mortality, and readmission. RESULTS: A total of six studies involving 846 patients were included (2009-2015), of which four were RCTs. Pooled analysis of RCTs and high-quality observational studies found no effect of restrictive intraoperative fluid management on POPF, DGE, complication rate, LOS, mortality, and readmission. Only one study assessed postoperative fluid management exclusively and found prolonged LOS in patients in the restricted fluid group. CONCLUSION: Based on results of RCTs and high-quality observational studies, intraoperative fluid restriction in PD has not been shown to significantly affect postoperative outcomes. There are too few studies assessing postoperative fluid management to draw conclusions at this time.

PMID- 29464349 TI - Treatment and outcome of patients with localized intrathoracic and chest wall rhabdomyosarcoma: a report of the Cooperative Weichteilsarkom Studiengruppe (CWS). AB - PURPOSE: Rhabdomyosarcoma (RMS) is the most common pediatric soft tissue sarcoma. In 7% of the cases it is localized at the chest wall or intrathoracically. The aim of this study was to analyze the multimodal treatment concepts and outcomes of children suffering from intrathoracic and chest wall RMS treated within three different Cooperative Soft Tissue Sarcoma (CWS) trials and one registry (Soft Tissue Sarcoma Registry, SoTiSaR). METHODS: Data of 51 patients with thoracic RMS enrolled in three different CWS trials (CWS-86, -91, -2002P) and one registry (SoTiSaR) were analyzed retrospectively. Surgery and its influence on outcome were assessed. Median follow-up was 37.5 months (0.9-152.5). RESULTS: Median age of the patients was 8.8 years (range 0-19 years). The 5-year overall survival rate (OS) was 57% (95%-CI 49-65) and the 5-year event-free survival rate (EFS) was 45% (38-52). Thirty-five patients had tumors located at the chest wall (EFS: 51%, 43-59), and 16 patients had intrathoracic tumors (EFS: 26%, 13-39). Seventeen patients with tumors <= 5 cm had a better outcome (EFS: 64%, 52-76) compared to patients with tumors larger than 5 cm (EFS: 36%, 27-45). Radiotherapy (RT) significantly improved the survival of patients with alveolar RMS compared to patients with embryonal histology (EFS: 66%, 52-80 vs. 32%, 21-43 p = 0.02). Complete tumor excision during delayed surgery was the main prognostic factor for survival (p = 0.045). CONCLUSION: Thoracic RMS is a rare tumor entity. Completeness of tumor resection significantly improved survival of the patients. PMID- 29464350 TI - NIPA-like domain containing 1 is a novel tumor-promoting factor in oral squamous cell carcinoma. AB - PURPOSE: In our previous global gene expression analysis, we identified NIPA-like domain containing 1 (NIPAL1), which encodes a magnesium transporter, as one of the most overexpressed genes in recurrent oral squamous cell carcinoma (OSCC). Although has been NIPAL1 linked with gout pathogenesis, little is known about its expression and function in human malignancies. METHODS: In this study, we examined NIPAL1 expression in 192 cases of OSCC by immunohistochemistry and performed a functional analysis of human OSCC cells. RESULTS: NIPAL1 immunostaining was observed in 39 of 192 OSCC patients (20.3%). NIPAL1 expression correlated significantly with cancer cell intravsation (P = 0.0062), as well as with poorer disease-free survival in a Kaplan-Meier analysis (P < 0.0001). Moreover, a multivariate Cox proportional hazards model analysis revealed that NIPAL1 expression was an independent predictor of disease-free survival in OSCC (P < 0.0001). In a functional analysis, NIPAL1 regulated the growth and adhesion of OSCC tumor cells and endothelial cells. CONCLUSIONS: Our findings suggest that NIPAL1 might be a novel factor promoting OSCC tumorigenesis, as well as a useful molecular marker of OSCC. PMID- 29464351 TI - Vasculitis in Africa. AB - PURPOSE OF REVIEW: Systemic vasculitides are characterized by inflammation of blood vessel walls leading to a myriad of organ disorders depending on the size, site, and location of the affected blood vessel. The epidemiology of vasculitis in the developing world has been inadequately documented. The description of the vasculitides in Africa, both from hospital series as well as taking into consideration, previous epidemiological studies in the community, indicates that these conditions have been rare until relatively recently. In view of these past observations, this review of publications on the topic looks to shed light on the current state of vasculitis in Africa. RECENT FINDINGS: Takayasu and Kawasaki appear to be the most commonly reported vasculitides in Africa. Most of the published reports are from North and South Africa. Furthermore, the contribution of vasculitis associated with infections, and in particular HIV, is significant. There are increasing numbers of publications reflecting a growing recognition of the vasculitides in Africa. PMID- 29464352 TI - Preparation of TPP-crosslinked chitosan microparticles by spray drying for the controlled delivery of progesterone intended for estrus synchronization in cattle. AB - PURPOSE: Planned reproduction in cattle involves regulation of estrous cycle and the use of artificial insemination. Cycle control includes the administration of exogenous progesterone during 5-8 days in a controlled manner allowing females to synchronize their ovulation. Several progesterone delivery systems are commercially available but they have several drawbacks. The aim of the present contribution was to evaluate chitosan microparticles entrapping progesterone as an alternative system. METHODS: Microparticles were prepared by spray drying. The effect of formulation parameters and experimental conditions on particle features and delivery was studied. A mathematical model to predict progesterone plasma concentration in animals was developed and validated with experimental data. RESULTS: Microparticle size was not affected by formulation parameters but sphericity enhances as Tween 80 content increases and it impairs as TPP content rises. Z potential decreases as phosphate content rises. Particles remain stable in acidic solution but the addition of surfactant is required to stabilize dispersions in neutral medium. Encapsulation efficiencies was 69-75%. In vitro delivery studies showed burst and diffusion-controlled phases, being progesterone released faster at low pH. In addition, delivery extend in cows was affected mainly by particle size and hormone initial content, while the amount injected altered plasma concentration. Theoretical predictions with excellent accuracy were obtained. CONCLUSION: The mathematical model developed can help to find proper particle features to reach specific delivery rates in the animals. This not only save time, money and effort but also minimized experimentation with animals which is desired from an ethical point of view. PMID- 29464353 TI - Cardio-pulmonary responses to incremental eccentric and concentric cycling tests to task failure. AB - PURPOSE: This study compared cardio-pulmonary responses between incremental concentric and eccentric cycling tests, and examined factors affecting the maximal eccentric cycling capacity. METHODS: On separate days, nine men and two women (32.6 +/- 9.4 years) performed an upright seated concentric (CON) and an eccentric (ECC) cycling test, which started at 75 W and increased 25 W min-1 until task failure. Gas exchange, heart rate (HR) and power output were continuously recorded during the tests. Participants also performed maximal voluntary contractions of the quadriceps (MVC), squat and countermovement jumps. RESULTS: Peak power output was 53% greater (P < 0.001, g = 1.77) for ECC (449 +/- 115 W) than CON (294 +/- 61 W), but peak oxygen consumption was 43% lower (P < 0.001, g = 2.18) for ECC (30.6 +/- 5.6 ml kg min-1) than CON (43.9 +/- 6.9 ml kg min-1). Maximal HR was not different between ECC (175 +/- 20 bpm) and CON (182 +/ 13 bpm), but the increase in HR relative to oxygen consumption was 33% greater (P = 0.01) during ECC than CON. Moderate to strong correlations (P < 0.05) were observed between ECC peak power output and CON peak power (r = 0.84), peak oxygen consumption (r = 0.54) and MVC (r = 0.53), while no significant relationships were observed between ECC peak power output and squat as well as countermovement jump heights. CONCLUSION: Unexpectedly, maximal HR was similar between CON and ECC. Although ECC power output can be predicted from CON peak power output, an incremental eccentric cycling test performed after 3-6 familiarisation sessions may be useful in programming ECC training with healthy and accustomed individuals. PMID- 29464354 TI - PARP inhibitors in platinum-sensitive high-grade serous ovarian cancer. AB - PURPOSE: Poly(ADP-ribose) polymerase inhibitors (PARPi) have changed the management of high-grade serous ovarian cancer (HGSOC). The rationale for the development of PARPi was based on the concept of synthetic lethality, in which a cell can survive a deficiency of one gene/gene product, but may die if there is a deficiency in a combination of genes/gene products. In women with BRCA1/2 deficiency within their ovarian cancer tissue, inhibition of PARP imposes an intolerable burden of DNA damage repair deficiency and may induce cell death. METHODS: Clinical trials have evaluated PARPi as single-agent therapeutics and as maintenance treatment following platinum-based chemotherapy for HGSOC. Clinical data suggest the most impressive anti-tumour activity occurs in women with platinum-sensitive ovarian cancer and germline or somatic BRCA1/2 mutations (g/sBRCAmt). RESULTS: In the maintenance setting, randomised trials have shown that PARPi compared to placebo reduce the hazard ratio for the development of progressive disease to 0.2-0.27 for patients with a g/sBRCAmt; to 0.34-0.38 for patients with putative evidence of DNA damage repair deficiency; and to 0.35-0.45 in an unselected population with HGSOC. Furthermore, phase 1/2 trials have reported single-agent anti-tumour response rates in gBRCAmt of approximately 50% in platinum-sensitive and 25% in platinum-resistant disease. CONCLUSION: Here, we discuss the evidence for the use of PARPi as single-agent therapeutics and maintenance treatment in HGSOC and evaluate the genetic assays used in clinical trials so far. We discuss the emerging role of platinum sensitivity as a broad eligibility criteria for the use of PARPi. PMID- 29464355 TI - FDG PET/CT after first molecular targeted therapy predicts survival of patients with renal cell carcinoma. AB - PURPOSE: We investigated prospectively whether 18F-2-fluoro-2-deoxyglucose positron emission tomography/computed tomography (FDG PET/CT) can predict the overall survival (OS) of patients with advanced renal cell carcinoma (RCC) previously treated by molecular targeted therapies. METHODS: Between 2009 and 2016, 81 patients who had received single molecular targeted therapies (43 sorafenib, 27 sunitinib, 8 temsirolimus and others) and were scheduled for second line molecular targeted therapies for advanced RCC were enrolled in this prospective study. FDG PET/CT was performed after first line molecular targeted therapies, the max SUVmax (highest standardized uptake value for each patient) recorded, and its association with OS compared with those of known risk factors. The median follow-up was 15.4 months (range 0.9-97.4 months). RESULTS: The max SUVmax of the 81 subjects ranged from undetectable to 23.0 (median 7.1). Patients with high max SUVmax had a poor prognosis and multivariate analysis with established risk factors showed that it was an independent predictor of survival (p < 0.001; hazard ratio 1.156; 95% confidence interval 1.080-1.239). Subclassification of patients by max SUVmax showed that the median OS of patients with max SUVmax < 7.0 (39), 7.0-12.0 (30), and >= 12.0 (12) were 32.8, 15.2, and 6.0 months, respectively. These differences are statistically significant (< 7.0 versus 7.0-12.0: p = 0.0333, 7.0-12.0 versus >= 12.0: p = 0.0235). CONCLUSIONS: The max SUVmax by FDG PET/CT of patients with RCC evaluated after their first molecular targeted therapy predicts OS. FDG PET/CT is a useful "imaging biomarker" for patients with advanced RCC planning sequential molecular targeted therapies.

AB - Sheehan's syndrome (SS) is an important cause of pan-hypopituitarism in women. There is scanty information on bone mineral density (BMD) in this condition. We determined BMD and the changes in BMD after oestrogen (E2) replacement and nutritional supplementation in women with SS. In a cross-sectional study, BMD was measured by DEXA in 83 patients [age (mean +/- SD) 42 +/- 9.2 years] and compared with an equal number of matched controls. In a sub-set of 19 patients, we conducted an open-label, prospective study to determine changes in BMD after 1 year of replacement of E2, and calcium and vitamin D3 supplementation. All patients had low serum IGF-1 and E2, while 98% had >= 3 pituitary hormone deficiencies. Compared with Indian reference standards, 47% had decreased bone mass (Z-score <= - 2.0). BMD Z-scores were decreased at all sites, being most marked in the lumbar spine and femoral neck. At the lumbar spine, BMD was lowest among the age group 21-30 years. Women with SS also had significantly lower BMD Z scores at all three sites on comparison with ethnic controls. On multivariate analysis, BMD Z-score was associated with weight, daily calcium intake and age (lumbar spine). In the prospective study, 1 year of therapy improved BMD Z-score at lumbar spine (- 1.4 +/- 1.2 vs. - 1.1 +/- 1.1, p = 0.02), but not at hip or femoral neck. In conclusion, patients with SS had significantly lower BMD compared to controls at all three sites. Replacement of E2 and supplementation with calcium/vitamin D3 lead to significant improvement in lumbar spine BMD.

AB - PURPOSE OF REVIEW: The role of aspirin in secondary cardiovascular prevention is well understood; however, the role in primary prevention is less clear, and requires careful balancing of potential benefits with risks. Here, we summarize the evidence base on the benefits and risks of aspirin therapy, discuss clinical practice guidelines and decision support tools to assist in initiating aspirin therapy, and highlight ongoing trials that may clarify the role of aspirin in cardiovascular disease prevention. RECENT FINDINGS: In 2016, the USPSTF released guidelines on the use of aspirin for primary prevention. Based on 11 trials (n = 118,445), aspirin significantly reduced all-cause mortality and nonfatal myocardial infarction, and in 7 trials that evaluated aspirin <= 100 mg/day, there was significant reduction in nonfatal stroke. The USPSTF recommends individualized use of aspirin based on factors including age, 10-year atherosclerotic cardiovascular disease risk score, and bleeding risk. Several ongoing trials are evaluating the role of aspirin in primary prevention, secondary prevention, and in combination therapy for atrial fibrillation. Evidence-based approaches to aspirin use should consider the anti-ischemic benefits and bleeding risks from aspirin. In this era of precision medicine, tools that provide the personalized benefit to risk assessment, such as the freely available clinical decision support tool (Aspirin-Guide), can be easily incorporated into the electronic health record and facilitate more informed decisions about initiating aspirin therapy for primary prevention. Aspirin has a complex matrix of benefits and risks, and its use in primary prevention requires individualized decision-making. Results from ongoing trials may guide healthcare providers in identifying appropriate candidates for aspirin therapy. PMID- 29464358 TI - Association of cystatin C- and creatinine-based eGFR with osteoporotic fracture in Japanese postmenopausal women with osteoporosis: sarcopenia as risk for fracture. AB - Coexistence of chronic kidney disease (CKD) is regarded as a risk for osteoporotic fracture particularly in postmenopausal women, not only because of increased parathyroid hormone level but also uremic sarcopenia. We examined the relationships of cystatin C-based glomerular filtration rate (eGFRcys) and creatinine-based GFR (eGFRcr), as well as their ratio with occurrence of osteoporotic fracture in postmenopausal osteoporotic women. This cross-sectional study included 555 postmenopausal women with osteoporosis. eGFRcr and eGFRcys were simultaneously measured, while occurrence of osteoporotic fracture was obtained by a medical chart review. Patients with osteoporotic fractures (n = 211) exhibited significantly lower levels of physical activity, eGFRcr, eGFRcys, and eGFRcys/eGFRcr ratios, while a higher percentage was CKD stage 3 or more, estimated by eGFRcr or eGFRcys (CKDcys), than those without (n = 344). Lower eGFRcys, but not lower eGFRcr, was independently associated with osteoporotic fracture in the entire cohort and that association was retained in CKDcys patients. Of great interest, higher eGFRcr was associated with osteoporotic fracture independent of eGFRcys in CKDcys patients. Furthermore, lower eGFRcys/eGFRcr ratio was independently associated with osteoporotic fracture in both CKDcys patients and the entire cohort. eGFRcys reduction might be associated with osteoporotic fracture in postmenopausal osteoporotic women, indicating the involvement of renal osteopathy in its occurrence. Furthermore, the association of higher, but not lower, eGFRcr with osteoporotic fracture in CKDcys cases might be explained by underestimation of renal dysfunction by eGFRcr resulting from decreased muscle mass and quality in those patients. PMID- 29464359 TI - Dentinal tubule obliteration using toothpastes containing sodium trimetaphosphate microparticles or nanoparticles. AB - OBJECTIVES: This in vitro study evaluated the effect of microparticles (TMPmicro) or nanoparticles (TMPnano) TMP associated with fluoride (F) in toothpaste formulations on the obliteration of dentinal tubules (DT). MATERIALS AND METHODS: The dentinal tubules of bovine dentin blocks were unobstructed by immersion in 37% phosphoric acid solution. Blocks (n = 20/group) underwent mechanical brushing (2*/day) during 7 days with toothpastes: placebo, 1100 ppm F, and 1100 with 3% TMPmicro or 3% TMPnano. After that, ten blocks of each group were immersed in citric acid (pH 3.2) for 1 min. The number, diameter and area of unobstructed DT, atomic % of chemical elements from precipitates, and the mineral concentration were quantified. Data were submitted to two-way ANOVA, followed by Student-Newman Keuls test (P < 0.05). RESULTS: Toothpastes containing TMPmicro and TMPnano promoted greater obliteration of DT and greater mineral concentration compared to other groups (P < 0.05). Placebo and 1100 ppm F group presented similar obliteration but 1100 ppm F group promoted higher mineral concentration. Higher Ca/P ratios were observed in groups treated with TMP; the acid challenge reduced Ca/P ratio for all groups. The atomic % of C and N was significantly lower for TMP toothpastes before acid challenge, but increased afterwards. CONCLUSIONS: It was concluded that the addition of TMPmicro or TMPnano to F toothpastes produced greater obliteration of dentinal tubules and higher mineral concentration when compared with 1100 ppm F. CLINICAL RELEVANCE: By the addition of TMP, fluoride toothpastes may occlude the dentinal tubules, with potential to reduce dentin hypersensitivity. PMID- 29464361 TI - Flavobacterium chungangensis sp. nov., a Bacterium Isolated from Soil of Chinese Cabbage Garden. AB - A novel bacterial strain MAH-10T was isolated from soil sample of a Chinese cabbage garden, Republic of Korea and was characterized using a polyphasic approach. Cells were Gram-staining negative, rod-shaped, yellowish orange colored, and motile. The strain was aerobic, catalase and oxidase are positive, and optimum growth temperature and pH were 28 degrees C and 6.5, respectively. Flexirubin-type pigments were found to be present. On the basis of 16S rRNA gene sequence analysis, strain MAH-10T belongs to the genus Flavobacterium and is most closely related to Flavobacterium tyrosinilyticum KCTC 42726T (98.7%). On the basis of phylogenetic tree, other closely related species are Flavobacterium banpakuense KACC 14225T (98.3%) and Flavobacterium chungbukense KACC 15048T (97.6%). In DNA-DNA hybridization tests, the DNA relatedness between strain MAH 10T and its closest phylogenetic neighbor was below 45.0%. The DNA G+C content was 37.2 mol% and the predominant respiratory quinone was menaquinone-6. The major cellular fatty acids were C15:0 iso, C16:0, and summed feature 3 (C16:1omega7c and/or C16:1omega6c). On the basis of DNA-DNA hybridization results and genotypic, chemotaxonomic, and physiological data analysis, it is demonstrated that strain MAH-10T represented a novel species within the genus Flavobacterium, for which the name Flavobacterium chungangensis is proposed. The type strain is MAH-10T (=KACC 19296T=CGMCC 1.16226T). The NCBI GenBank accession number for the 16S rRNA gene sequence of strain MAH-10T is KY964277 and the digital protologue database (DPD) Taxon Number of strain MAH-10T is TA00296. PMID- 29464360 TI - Identification and Analysis of a Novel Gene Cluster Involves in Fe2+ Oxidation in Acidithiobacillus ferrooxidans ATCC 23270, a Typical Biomining Acidophile. AB - Iron-oxidizing Acidithiobacillus spp. are applied worldwide in biomining industry to extract metals from sulfide minerals. They derive energy for survival through Fe2+ oxidation and generate Fe3+ for the dissolution of sulfide minerals. However, molecular mechanisms of their iron oxidation still remain elusive. A novel two-cytochrome-encoding gene cluster (named tce gene cluster) encoding a high-molecular-weight cytochrome c (AFE_1428) and a c4-type cytochrome c552 (AFE_1429) in A. ferrooxidans ATCC 23270 was first identified in this study. Bioinformatic analysis together with transcriptional study showed that AFE_1428 and AFE_1429 were the corresponding paralog of Cyc2 (AFE_3153) and Cyc1 (AFE_3152) which were encoded by the extensively studied rus operon and had been proven involving in ferrous iron oxidation. Both AFE_1428 and AFE_1429 contained signal peptide and the classic heme-binding motif(s) as their corresponding paralog. The modeled structure of AFE_1429 showed high resemblance to Cyc1. AFE_1428 and AFE_1429 were preferentially transcribed as their corresponding paralogs in the presence of ferrous iron as sole energy source as compared with sulfur. The tce gene cluster is highly conserved in the genomes of four phylogenetic-related A. ferrooxidans strains that were originally isolated from different sites separated with huge geographical distance, which further implies the importance of this gene cluster. Collectively, AFE_1428 and AFE_1429 involve in Fe2+ oxidation like their corresponding paralog by integrating with the metalloproteins encoded by rus operon. This study provides novel insights into the Fe2+ oxidation mechanism in Fe2+-oxidizing A. ferrooxidans ssp. PMID- 29464362 TI - Inhibitory Mechanism on Combination of Phytic Acid with Methanolic Seed Extract of Syzygium cumini and Sodium Chloride over Bacillus subtilis. AB - The antibiotic resistance in bacteria responsible for causing community and health care-associated infection displayed a major threat to global health. Use of broad-spectrum antibiotics for the treatment of various ailments poses serious side effects. In the present research, we investigated the combined role of 2% phytic acid with 2% methanolic seed extract of Syzygium cumini and 0.5% sodium chloride for inhibition of Bacillus subtilis and Pseudomonas aeruginosa and found it to be efficient over B. subtilis. The zone of inhibition by present mixture was found to be 2.9 +/- 0.0004 and 1.9 +/- 0.0006 cm against Bacillus subtilis and P. aeruginosa in comparison to individual component. Mixture was found more potent against B. subtilis and selected for further study. The underlying mechanism involved in inhibitory action of this mixture was determined by Scanning electron microscope, DNA fragmentation and propidium iodide staining. Scanning electron microscopy revealed that inhibition of B. subtilis by this mixture is mainly due to the disruption of bacterial cell membrane, leakage of internal cellular content which ultimately leads to the death of bacterial cells. DNA fragmentation showed apoptotic hallmark through degradation caused by mixture against B. subtilis at various time intervals. Likewise, PI staining also revealed the disruption of bacterial membrane by the mixture as the PI gives fluorescence after binding with DNA. The present study concludes that inhibitory potential of this mixture is mainly due to disruption of bacterial cell membrane, degradation of DNA and creation of pores in the membrane. The mixture could be used for inhibition of food pathogen B. subtilis. PMID- 29464364 TI - Fatty acids promote bovine skeletal muscle satellite cell differentiation by regulating ELOVL3 expression. AB - Fatty acids (FAs) play essential roles in regulating differentiation and proliferation by affecting gene expression in various cell types. However, their potential functions in bovine cells remain unclear. Herein, we examine the differentiation and proliferation of bovine skeletal muscle-derived satellite cells (MDSCs) after incubation with three types of representative FAs (palmitic acid, oleic acid and docosahexaenoic acid) by western blotting, immunofluorescence assays, flow cytometry analysis and EdU incorporation assays. The myotube fusion rate, myotube length and expression levels of muscle differentiation-related gene myogenin (MYOG) and myosin heavy chain 3 (MYH3) increased significantly, although the FAs did not affect proliferation. Additionally, FA-induced bovine MDSC differentiation increased ELOVL3 expression and relocation of ELOVL3 to cytoplasmic lipid droplets in the differentiation of bovine MDSCs. Moreover, the effect of FAs on bovine MDSC differentiation was inhibited upon ELOVL3 downregulation. Collectively, these data indicate that FAs promote bovine MDSC differentiation by regulating ELOVL3 expression. PMID- 29464363 TI - Corallibacterium pacifica gen. nov., sp. nov., a Novel Bacterium of the Family Vibrionaceae Isolated from Hard Coral. AB - A gram-negative, rod-shaped, motile, oxidase- and catalase-positive, non pigmented marine bacterium, designated strain OS-11M-2T, was isolated from a coral sample collected from the Osakura coastal area in Micronesia. Phylogenetic analysis based on 16S ribosomal RNA (rRNA) gene sequences indicated that strain OS-11M-2T is a member of the family Vibrionaceae, its closest neighbors being Photobacterium damselae subsp. piscicida NCIMB 2058T (94.9%), Photobacterium damselae subsp. damselae CIP 102761T (94.75%), Grimontia marina IMCC5001T (94.5%), Enterovibrio coralii LMG 22228T (94.5%), and Grimontia celer 96-237T (94.5%). The major cellular fatty acids were summed feature 3 (21.4%), summed feature 8 (18.5%), iso-C16:0 (13.8%), and C16:0 (11.9%). The major respiratory quinone of the bacterium was ubiquinone-8 (Q-8) and its major polar lipid phosphatidylethanolamine. Six amino lipids, two phospholipids, and one polar lipid, all unidentified, were detected. The DNA G+C content was 49.7 mol%. The 16S rRNA gene sequence of OS-11M-2T was registered in GenBank under accession number MF359550. On the basis of phenotypic, genotypic, and phylogenetic analyses, strain OS-11M-2T represents a novel genus of the family Vibrionaceae, for which we propose the name Corallibacterium pacifica gen. nov., sp. nov., with the type strain of the type species being OS-11M-2T (= KCCM 43265T). The digital protologue database (DPD) taxon number for strain OS-11M-2T is GA00041. PMID- 29464365 TI - Structural and functional maturation of skin during metamorphosis in the Atlantic halibut (Hippoglossus hippoglossus). AB - To establish if the developmental changes in the primary barrier and osmoregulatory capacity of Atlantic halibut skin are modified during metamorphosis, histological, histochemical, gene expression and electrophysiological measurements were made. The morphology of the ocular and abocular skin started to diverge during the metamorphic climax and ocular skin appeared thicker and more stratified. Neutral mucins were the main glycoproteins produced by the goblet cells in skin during metamorphosis. Moreover, the number of goblet cells producing neutral mucins increased during metamorphosis and asymmetry in their abundance was observed between ocular and abocular skin. The increase in goblet cell number and their asymmetric abundance in skin was concomitant with the period that thyroid hormones (THs) increase and suggests that they may be under the control of these hormones. Several mucin transcripts were identified in metamorphosing halibut transcriptomes and Muc18 and Muc5AC were characteristic of the body skin. Na+, K+-ATPase positive (NKA) cells were observed in skin of all metamorphic stages but their number significantly decreased with the onset of metamorphosis. No asymmetry was observed between ocular and abocular skin in NKA cells. The morphological changes observed were linked to modified skin barrier function as revealed by modifications in its electrophysiological properties. However, the maturation of the skin functional characteristics preceded structural maturation and occurred at stage 8 prior to the metamorphic climax. Treatment of Atlantic halibut with the THs disrupter methimazole (MMI) affected the number of goblet cells producing neutral mucins and the NKA cells. The present study reveals that the asymmetric development of the skin in Atlantic halibut is TH sensitive and is associated with metamorphosis and that this barrier's functional properties mature earlier and are independent of metamorphosis. PMID- 29464366 TI - Peritoneal fluid of women with endometriosis reduces SOD1 in bovine oocytes in vitro maturation. AB - Studies have demonstrated oxidative stress in peritoneal fluid (PF) from women with endometriosis and the importance of enzymatic antioxidant machinery to avoid oocyte oxidative damage. Considering that PF constantly surrounds the ovaries and has direct contact with the oocyte at ovulation, we wonder if PF from women with endometriosis may affect antioxidant enzyme gene expression. Thus, the present study aims to evaluate the PF impact from infertile women with minimal and mild endometriosis and from fertile control women without endometriosis on SOD1, CAT, GSR gene's expression in experimental bovine oocytes matured in vitro. Samples of PF were obtained from women who underwent videolaparoscopy-7 infertile with EI/II and 7 fertile without endometriosis. Immature bovine oocytes underwent in vitro maturation in the absence of PF and in the presence of three concentrations (1, 5 and 10%) of PF from fertile and from infertile women with EI/II. After 22 to 24 h of IVM, oocytes were denuded and stored for analysis of SOD1, CAT and GSR by real time polymerase chain reaction. Oocyte SOD1 expression was significantly lower in the 10% endometriosis group (0.67 +/- 0.32) when compared with no-peritoneal fluid (1.05 +/- 0.24, p < 0.008) and 10% control groups (1.06 +/- 0.22, p < 0.006). These findings raise the possibility of a deleterious influence of PF from women with EI/II on the oocyte, not only after ovulation but also during the maturation process, which could contribute to worsening oocyte quality, being one of the mechanisms related to infertility in patients with endometriosis. PMID- 29464367 TI - Inalambric Biofeedback Devices to Analyze Strength Manifestation in Military Population. AB - The study of the effect of stress on both combatants physiological and anatomical systems have been poor studied in the specific literature. The present research aimed to study the effect of combat stress in strength manifestations of leg flexor-extensor muscles and the anaerobic metabolism of soldiers. Before and after asymmetrical combat simulation were analyzed parameters of blood lactate concentration, explosive leg strength manifestation and contractile capacity of leg muscle in 186 professional soldiers. Results showed a significant increase (p < 0.05) in blood lactate values (2.23 +/- 0.95 vs 7.47 +/- 3.67 mmol/L), explosive leg strength (Squat Jump 0.31 +/- 0.06 vs 0.35 +/- 0.07 m, Countermovement Jump 0.33 +/- 0.07 vs 0.36 +/- 0.07 m, Abalakov Jump 0.39 +/- 0.08 vs 0.41 +/- 0.09 m), and a significant decrease of the elastic capacity (0.022 +/- 0.04 vs 0.021 +/- 0.04) and recruitment and muscle synchronization capability (0.028 +/- 0.04 vs 0.026 +/- 0.04). This data suggest that combat stress increases the leg strength manifestation despite the significantly increase of muscle acidosis after a combat simulation. This result is probably due to the high activation of the fight-flight system of soldiers which increases the organic response of soldiers and that can compensate the prejudicial effect of acidosis in muscle contraction. These results could be used by officers to improve specific training programs and to improve planning and election of equipment and material for the development of different missions in current theaters of operations.

AB - PURPOSE: We aimed to investigate the status quo of orthopaedic publications from China and characterize the most-cited articles to provide valuable insights for orthopaedists. METHODS: PubMed and Embase databases were used to search for Chinese orthopaedic publications from 1997 to 2017 to determine the growing pattern of Chinese research globally. Then Web of Science database was searched for articles with most citations in all journals included in the Journal Citation Report 2016 under the category of "orthopaedics" for the last five years, and the total numbers of articles in the last three respective years were also analyzed. RESULTS: The number of publications published in PubMed and Embase during the last 20 years ranged from 218 to 6836, and year 2002 had the biggest growth rate of 59.15% and 2014 had the biggest growth value of 1203, comparing with previous years. Fifty-three articles were selected as the most-cited ones for the last five years. European Spine Journal and West China Hospital are the journal and institution that published the most high-impact articles. Majority of the articles (47%) were meta-analysis, and 6 RCTs were identified in a total of 11 clinical articles. Most high-cited clinical articles or meta-analyses were classified as level of evidence of I (41.67%).A total of 1238 articles, 1264 articles, and 1225 articles in the field of orthopedics from China were included in SCI for the last three years. CONCLUSION: The Chinese orthopaedic research grew rapidly in terms of number of publications in the last decades, and the quality of publications also improved in recent years. PMID- 29464370 TI - Morphometric evaluation of the knee in Chinese population reveals sexual dimorphism and age-related differences. AB - PURPOSE: Morphologic data of the knee is very important in the design of total knee prostheses. Generally, the designs of the total knee prostheses are based on the knee anatomy of Caucasian population. Moreover, in forensic medicine, a person's age and sex might be estimated by the shape of their knees. The aim of this study is to utilize three-dimensional morphometric analysis of the knee in Chinese population to reveal sexual dimorphism and age-related differences. MATERIALS AND METHODS: Sexually dimorphic differences and age-related differences of the distal femur were studied by using geometric morphometric analysis of ten osteometric landmarks on three-dimensional reconstructions of 259 knees in Chinese population. General Procrustes analysis, PCA, and other discriminant analysis such as Mahalanobis and Goodall's F test were conducted for the knee to identify sexually dimorphism and age-related differences of the knee. RESULTS: The shape of distal femur between the male and female is significantly different. A difference between males and females in distal femur shape was identified by PCA; PC1 and PC2 accounted for 61.63% of the variance measured. The correct sex was assigned in 84.9% of cases by CVA, and the cross-validation revealed a 81.1% rate of correct sex estimation. The osteometric analysis also showed significant differences between the three age-related subgroups (< 40, 40-60, > 60 years, p < 0.005). CONCLUSION: This study showed both sex-related difference and age-related difference in the distal femur in Chinese population by 3D geometric morphometric analysis. Our bone measurements and geometric morphometric analysis suggest that population characteristics should be taken into account and may provide references for design of total knee prostheses in a Chinese population. Moreover, this reliable, accurate method could be used to perform diachronic and interethnic comparisons. PMID- 29464371 TI - Risk factor analysis for re-collapse of cemented vertebrae after percutaneous vertebroplasty (PVP) or percutaneous kyphoplasty (PKP). AB - PURPOSE: Re-collapse of cemented vertebrae occasionally occurs after percutaneous augmentation. However, the potential risks still remain unclear. Several articles have reported some possible risk factors which were not consistent or comprehensive. This study aimed to make a retrospective review on patients with osteoporotic vertebral compression fracture (OVCF) after percutaneous vertebroplasty (PVP) or percutaneous kyphoplasty (PKP) and to further analyse the risk factors for treated vertebral refracture. METHODS: All patients receiving the PKP/PVP with bilateral approach were retrospectively reviewed from January 2014 to January 2016, among whom 230 patients with single level augmentation (30 in refracture group and 200 in the non-refracture group) were enrolled according to inclusion criteria. The following covariates were reviewed: gender, age, height, weight, body mass index (BMI), bone mineral density (BMD), serum bone turnover markers, surgical parameters including approach, cement volume, anterior height, and Cobb angle restoration. Binary logistic regression analysis was used to determine the relative risk of re-collapse of cemented vertebrae. RESULTS: Regarding the patient data, weight, BMI, and BMD were of statistical significance in refracture group (P < 0.01), among which only low BMD was a risk factor to cemented vertebral re-collapse (P = 0.022, OR = 4.197). In respect of surgical variables, the better restoration of anterior height and Cobb angle was found in refracture group (P < 0.05), both of which might increase the refracture risk but not be risk factors (P = 0.065, OR = 0.891, and P = 0.937, OR = 0.996, respectively). Besides, less injected cement (3.30 +/- 0.84 ml vs 4.46 +/- 1.10 ml, P = 0.000, OR = 19.433) and PKP (P = 0.007, OR = 13.332) significantly boosted the potential risk of refracture (P < 0.001). CONCLUSION: Patients with low BMD, or undergoing PKP, or receiving a low volume of injected cement might have a high risk of re-collapse in surgical vertebrae. PMID- 29464372 TI - Long-term results of total knee arthroplasty after failed high tibial osteotomy. AB - PURPOSE: Sometimes, total knee replacement (TKR) is performed after a tibial osteotomy. It is not known if the osteotomy influences the clinical process of a TKR. The aim of this study was to look at the clinical outcome of a TKR after high tibial osteotomy (HTO) compared to a TKR with no HTO. METHODS: Between 1995 and 2005, 41 post-HTO TKRs (group A) with a minimum follow-up of ten years were selected. In parallel, it was selected a control group undergoing simple TKR, consisting of 41 patients (group B) matched with group A. The Knee Society Knee Score (KS), Knee Score Functional Score (FS), the Oxford Knee Score (OKS), and the range of motion (ROM) were used for evaluation at one, five and ten years after surgery. The Insall-Salvatti ratio (ISR), the posterior tibial slope (PTS), and the joint height line (JHL) were also measured both pre-operatively and post operatively. RESULTS: No differences were found between both groups in KS, FS, OKS, and ROM at the pre-operative stage or at any of the post-operative controls. Higher patellar height was found in group A, both pre-operatively and post operatively (p < 0.005), and the same for PTS pre-operative (p < 0.001) and post operative (p < 0.05). No differences were found regarding the JHL. Post-operative differences were found among the post-HTO subgroups at the FS (p < 0.02), the OKS (p < 0.05), and the ROM (p < 0.01) as a function of whether there was a varus or a valgus deformity before the TKR. CONCLUSION: A HTO was not determinant for having a worse outcome at the TKR, even when there were radiographic differences. The coronal alignment with valgus deformity pre-TKR after a HTO showed better functional results than in the case of varus deformity. Level of evidence III.

PMID- 29464374 TI - Heterogeneous pattern of autonomic dysfunction in Parkinson's disease. AB - Dysautonomic symptoms are frequent non-motor complaints in patients with Parkinson's disease. Numerous neuropathological studies have shown that Lewy bodies and neurites, the pathological hallmarks of Parkinson's disease, are widely distributed throughout the peripheral autonomic nervous systems and across end organs. However, few investigations integrally explored the symptoms and physiology of dysautonomia in Parkinson's disease. We, therefore, performed a comprehensive evaluation of the autonomic function in a prospective group of 45 patients with idiopathic Parkinson's disease. Autonomic components (pupillomotor, tear, salivary, cardiovascular, digestive, urinary, sexual, sudomotor functions and skin sensitivity) were evaluated using questionnaires and functional tests. Skin biopsy was performed for intraepidermal nerve fibre density quantification. In addition, all patients underwent polysomnography and a complete neuropsychological and neurological assessment. The analysis association of autonomic components showed that dysautonomic signs and symptoms were heterogeneously distributed among patients. Skin denervation as assessed by intraepidermal nerve fibre density quantification was only associated with quantitative thermal sensory testing (OR = 12.0, p = 0.02), constipation (OR = 5.5, p = 0.01) and ocular dryness symptoms (OR = 8.29, p = 0.04). Cognitive alteration was associated with cardiovascular symptoms (OR = 4.33, p = 0.03) and dysfunction (OR = 5.83, p = 0.02) as well as with constipation (OR = 5.38, p = 0.02). Axial motor impairment and rapid eye movement (REM) sleep behaviour disorder were not related to any of the autonomic complaint or dysfunction. Our results show that autonomic functions are affected in a heterogeneous pattern in Parkinson's disease, thereby suggesting that the progression of autonomic dysfunction follows an erratic rather than a stepwise progression.

AB - BACKGROUNDS: The previous studies on the association between marital status and stroke outcomes were rare. Furthermore, the existing studies mostly focused on the protective effect of marriage on survival. We conducted the study to evaluate the association between marital status and adverse stroke outcomes in patients with AIS based on China national stroke registry. METHODS: This was a multicenter, prospective cohort study of patients with AIS. Patients were classified into two groups based on marital status at admission: married and unmarried. The primary outcomes included all-cause mortality, stroke recurrence, combined endpoint, and stroke disability. Stroke disability was defined as modified Rankin Scale of 2-6. RESULTS: Of 12,118 patients, 1220 were unmarried and 10,898 married. Unmarried patients had higher proportion of 1-year post stroke events than married patients did. As compared with being unmarried, the adjusted odds ratios with 95% confidence interval of being married for outcomes were as follows: 0.70 (0.58-0.84) for all-cause mortality, 0.78 (0.66-0.91) for stroke recurrence, 0.77 (0.66-0.90) for combined endpoint, and 0.75 (0.65-0.88) for stroke disability. Interactions between marital status and education were significant for all outcomes except for stroke disability. CONCLUSIONS: Marital status was associated with all adverse stroke outcomes in patients with acute ischemic stroke, especially in those with middle-school education. PMID- 29464376 TI - In vivo assessment of retinal vessel pathology in amyotrophic lateral sclerosis. AB - BACKGROUND: Changes in skin and muscle small blood vessels (SBVs) and microvascular structures of the brain have been reported in patients with amyotrophic lateral sclerosis (ALS). A direct assessment of brain SBVs in vivo is currently not feasible. Retinal vessels are considered a "mirror" of brain SBVs. In this study, we used optic coherence tomography (OCT)-based measurements to detect changes in retinal blood vessels of ALS patients compared to those of healthy controls. METHODS: We analysed Spectralis-OCT images of 34 ALS patients and 20 HCs. The inner wall thickness (IWT), outer wall thickness (OWT), and lumen diameter (LD) of retinal vessels were assessed using intensity-based measurements. In addition, the different retinal layers were analysed using automated segmentation software. The correlations between the various retinal layers and clinical parameters [e.g., disease duration and revised ALS functional rating scale (ALS-FRS-R)] were examined. RESULTS: The OWT of retinal vessels was higher in ALS patients than in HCs (p = 0.04). There were no differences in the IWT, LD. ALS patients showed a thinning of the outer nuclear layer (ONL) compared to HCs (median 1.63 vs. 1.77, p = 0.002). The whole retinal thickness negatively correlated with the ALS-FRS scale (r = 0.3, p = 0.03). CONCLUSION: Our study reports retinal vessel pathology in ALS patients. These changes may be related to those observed in SBVs in skin and muscle biopsies. Furthermore, we report a thinning of the ONL in ALS, revealing a possible affection of rods and cones function in ALS. PMID- 29464377 TI - Is oral feeding compatible with an unresponsive wakefulness syndrome? AB - OBJECTIVE: The aim of the study is to explore the possibility of oral feeding in unresponsive wakefulness syndrome/vegetative state (UWS/VS) patients. METHOD: We reviewed the clinical information of 68 UWS/VS patients (mean age 45 +/- 11; range 16-79 years) searching for mention of oral feeding. UWS/VS diagnosis was made after repeated behavioural assessments using the Coma Recovery Scale Revised. Patients also had complementary neuroimaging evaluations (positron emission tomography, functional magnetic resonance imaging and electroencephalography and diffusion tensor imaging). RESULTS: Out of the 68 UWS/VS patients, only two could resume oral feeding (3%). The first patient had oral feeding (only liquid and semi liquid) in addition to gastrostomy feeding and the second one could achieve full oral feeding (liquid and mixed solid food). Clinical assessments concluded that they fulfilled the criteria for a diagnosis of UWS/VS. Results from neuroimaging and neurophysiology were typical for the first patient with regard to the diagnosis of UWS/VS but atypical for the second patient. CONCLUSION: Oral feeding that implies a full and complex oral phase could probably be considered as a sign of consciousness. However, we actually do not know which components are necessary to consider the swallowing conscious as compared to reflex. We also discussed the importance of swallowing assessment and management in all patients with altered state of consciousness. PMID- 29464378 TI - Smoking at time of CIS increases the risk of clinically definite multiple sclerosis. AB - BACKGROUND: Cigarette smoking is a modifiable risk factor that influences the disease course of patients with multiple sclerosis (MS). However, in patients with a clinically isolated syndrome (CIS), there are conflicting results about the association between smoking and the risk of a subsequent MS diagnosis. The aim of this study was to determine the risk of clinically definite MS (CDMS) in smoking and non-smoking patients at time of a first demyelinating event. METHODS: Two hundred and fifty patients, aged 18-50 years, were included in our prospective CIS cohort. At time of the first neurological symptoms, patients completed a questionnaire about smoking habits. Cox regression analyses were performed to calculate univariate and multivariate hazard ratios for CDMS diagnosis in smoking and non-smoking CIS patients. RESULTS: One hundred and fourteen (46%) CIS patients were diagnosed with CDMS during a mean follow-up of 58 months. In total, 79 (32%) patients smoked at time of CIS. Sixty-seven % of the smoking CIS patients were diagnosed with CDMS during follow-up compared to 36% of the non-smoking CIS patients (p < 0.001). Smoking at time of CIS was an independent predictor for CDMS diagnosis (HR 2.3; p = 0.002). Non-smoking CIS patients who had a history of smoking did not have a higher risk for CDMS than those who had never smoked. CONCLUSIONS: Smoking at time of CIS was an independent risk factor for a future CDMS diagnosis. This is an additional argument to quit smoking at time of the first attack of suspected MS. PMID- 29464379 TI - Positive effects of fampridine on cognition, fatigue and depression in patients with multiple sclerosis over 2 years. AB - OBJECTIVE: To assess the effects of PR-fampridine on cognitive functioning, fatigue and depression in patients with multiple sclerosis (PwMS). METHODS: Thirty-two PwMS were included in this trial. Cognitive performance was assessed in an open-label and randomized double-blind, placebo-controlled study design using a comprehensive neuropsychological test battery as well as questionnaires examining depression and fatigue. RESULTS: We found significant improvements in cognitive measures assessing alertness (tonic alertness, p = 0.0244 and phasic alertness, p = 0.0428), psychomotor speed (p = 0.0140) as well as verbal fluency (p = 0.0002) during open-label treatment with PR-fampridine. These effects of performance were paralleled by patients' perception of reduced fatigue (physical, p = 0.0131; cognitive, p = 0.0225; total, p = 0.0126). Fampridine-induced improvements in phasic alertness (p = 0.0010) and measures of fatigue (physical, p = 0.0014; cognitive, p = 0.0003; total, p = 0.0005) were confirmed during randomized, double-blind, placebo-controlled assessment in the second year. In addition, we found positive effects of PR-fampridine on depressive symptoms (p = 0.0049). We demonstrated persisting beneficial effects of PR-fampridine on fatigue in PwMS over a period of more than 2 years. Drug responsiveness regarding cognitive performance and fatigue was not limited to walking responders. CONCLUSIONS: Our data demonstrate significant positive effects of treatment with PR-fampridine over 2 years on different cognitive domains as well as fatigue and depression in a cohort of PwMS. These findings imply that PR-fampridine should be considered as symptomatic treatment improving aspects of cognition, fatigue and depression in PwMS. PMID- 29464381 TI - Is mental time embodied interpersonally? AB - Recent evidence has shown that the mental representation of time is "embodied" time is expressed via the hands, the eyes, and the whole body. These findings suggest the existence of a manually reflected mental time line running (in Western culture) horizontally from left (past) to right (future) and an ocularly reflected mental time line running from left/down (past) to right/up (future). We addressed the question whether mental time is also reflected interpersonally and investigated whether an avatar's face orientation (left vs. right) would facilitate a subject's temporal processing in relation to the horizontal mental time line. In combination with a left- or right-gazing avatar, we presented a temporal auditory word ("gestern"-yesterday or "morgen"-tomorrow), and our subjects had to manually categorize the word as being either past- or future related (classic left/right key-press paradigm). The stimulus-response (SR) mapping was either compatible (past word-left hand, future word-right hand) or incompatible (future word-left hand, past word-right hand). Responses were significantly faster in blocks with compatible versus incompatible mapping. Thus, our results provide clear evidence for manually reflected mental time running from left to right, even for temporal auditory words that are free of potential visual (reading direction) confounds. The presented interpersonal cues (avatar head orientation) facilitated the activation of the horizontal mental time line in blocks with incompatible SR-mapping but not in blocks with compatible (standard) mapping. We conclude that interpersonal cues exert weak effects on the spatial representation of mental time and can help to adapt context-specific mappings of temporal concepts. PMID- 29464382 TI - Repair of the Severe Muscle Aponeurotic Abdominal Laxity with Alloplastic Mesh in Aesthetic Abdominoplasty. AB - BACKGROUND: Abdominoplasty is the most frequently performed surgical procedure for body contour; in our experience, we have observed some patients with prominent bulging that is difficult to treat and that presents results that are unsatisfactory or have recurrences to conventional treatments. This leads us to carry out an analysis of the elements responsible for the containment and abdominal format. We determined that it may be due to an inability of an important sagging aponeurotic muscle of primary origin to support the abdomen and could be caused by predisposing factors. For these specific cases, we developed a treatment proposing the use of a mesh. METHODS: We present these cases over a period of 24 years. Fourteen patients were treated with primary and secondary abdominoplasties. The abdominal wall reinforcement was performed by placing polypropylene mesh at the sub-muscular plane, fixed with U-stitches on the fascia transversalis, seeking to strengthen the muscle and the fascia transversalis. RESULTS: The results were satisfactory after long-term observation, gaining resolution of the abdominal bulges. Only two complications occurred; the presence of localized chronic pain and the appearance of umbilical fistula. DISCUSSION: We emphasize the importance of avoiding unnecessary interventions in patients with marked bulging, associated with inability of abdominal restraint. We only consider its indications in patients with conventional recurrence treatment, also identifying the predisposing factors, the knowledge of the abdominal anatomy, the muscular dynamics of the abdomen and understanding its indication in these specific cases of difficult treatment.

PMID- 29464380 TI - The metabolic and endocrine characteristics in spinal and bulbar muscular atrophy. AB - OBJECTIVE: Spinal and bulbar muscular atrophy (SBMA) is caused by an abnormal expansion of the CAG repeat in the androgen receptor gene. This study aimed to systematically phenotype a German SBMA cohort (n = 80) based on laboratory markers for neuromuscular, metabolic, and endocrine status, and thus provide a basis for the selection of biomarkers for future therapeutic trials. METHODS: We assessed a panel of 28 laboratory parameters. The clinical course and blood biomarkers were correlated with disease duration and CAG repeat length. A subset of 11 patients was evaluated with body fat MRI. RESULTS: Almost all patients reported muscle weakness (99%), followed by dysphagia (77%), tremor (76%), and gynecomastia (75%) as major complaints. Creatine kinase was the most consistently elevated (94%) serum marker, which, however, did not relate with either the disease duration or the CAG repeat length. Paresis duration and CAG repeat length correlated with dehydroepiandrosterone sulfate after correction for body mass index and age. The androgen insensitivity index was elevated in nearly half of the participants (48%). CONCLUSIONS: Metabolic alterations in glucose homeostasis (diabetes) and fat metabolism (combined hyperlipidemia), and sex hormone abnormalities (androgen insensitivity) could be observed among SBMA patients without association with the neuromuscular phenotype. Dehydroepiandrosterone sulfate was the only biomarker that correlated strongly with both weakness duration and the CAG repeat length after adjusting for age and BMI, indicating its potential as a biomarker for both disease severity and duration and, therefore, its possible use as a reliable outcome measure in future therapeutic studies. PMID- 29464383 TI - Concentric Malar Lift in the Management of Lower Eyelid Rejuvenation or Retraction: A Clinical Retrospective Study on 342 Cases, 13 Years After the First Publication. AB - BACKGROUND: Lower eyelid rejuvenation can, unfortunately, induce scleral show even if the lower eyelid procedure is limited. This study was designed to assess the effectiveness and reliability of the concentric malar lift technique in two scenarios: the first, in rejuvenation of the mid-face and, the second, in reconstructive surgery for correction of congenital or acquired eyelids malposition. METHODS: The concentric malar lift technique was first published by Le Louarn (Aesthet Plast Surg 28(6):359-372, 2004). This retrospective study was carried out by analyzing data on patients operated on between January 2010 and January 2016. Patients operated on before 2010 were excluded because barbed thread sutures were not used in the first version of the technique. Patients after January 2016 were excluded to ensure adequate follow-up, and so 342 patients are included in the study. A total of 256 cases (75%) were for aesthetic mid-face lifting, and 86 cases (25%) were reconstructive surgeries for lower eyelid retraction. A spacer graft was used in 30 of these reconstructive cases (35%). The mean follow-up time was 13.6 months. All the concentric malar lifting procedures included strengthening the lateral canthus, which is a key element of the procedure. RESULTS: None of the patients developed secondary eyelid malposition, and all the cases of lower eyelid retraction displayed marked improvement both functionally and aesthetically. Two patients experienced loss of sensitivity of part in the infra-orbital nerve distribution for 4 months after the procedure. CONCLUSION: The concentric malar lift procedure enables the recruitment of a significant amount of skin into the lower eyelid: between 10 and 30 mm. It ensures better rejuvenation of the mid-face with minimal risk of lower eyelid malposition. In reconstruction of the lower eyelid lid, the concentric malar lift is able to reduce the need for skin grafting and a skin flap reducing the risks of visible scarring.

PMID- 29464384 TI - Versajet-Assisted Hydraulic Epilation Through Small Incisions for Axillary Osmidrosis. AB - BACKGROUND: Osmidrosis is a malodorous disease caused by the breakdown of sweat secreted from the apocrine glands by surface bacteria. The aim of this study was to evaluate the effect of Versajet-assisted hydraulic epilation for the treatment of axillary osmidrosis. METHODS: Thirty-two patients with axillary osmidrosis (64 axillae) underwent Versajet-assisted hydraulic epilation between January 2016 and January 2017. Subjective assessments were evaluated by a patient survey at least 3 months after the procedure. RESULTS: There were no complications other than one mild pigmentation in the axilla at 3 months after the procedure. Thirty-two patients evaluated malodor elimination as good. No patients evaluated it as fair or poor. There were no recurrences. CONCLUSION: Versajet-assisted hydraulic epilation is an ideal surgical procedure for the treatment of axillary osmidrosis that decreases complications and recurrence.

PMID- 29464385 TI - Prevention of Emergence Agitation with Ketamine in Rhinoplasty. AB - BACKGROUND: Emergence agitation (EA), defined as restlessness, disorientation, excitation, and/or inconsolable crying, is a common phenomenon during early recovery from general anesthesia. In this study, we aimed to determine the (1) EA incidence after rhinoplasty operations in adults; (2) the effects of ketamine administered at sub-anesthetic doses just 20 min before the end of the surgery in rhinoplasty operations on agitation level, postoperative pain, side effects, and complications; and (3) to determine the risk factors for EA in adults after rhinoplasty. MATERIALS AND METHODS: Totally 140 patients scheduled to undergo elective rhinoplasty were enrolled in this prospective study. Patients were equally and randomly divided into two groups: saline group (control group) (n = 70) and ketamine group (n = 70). Twenty minutes before surgery completion, 1 ml saline was administered via the intravenous (i.v.) route to the saline group, while 0.5 mg/kg ketamine was administered via i.v. patients in the ketamine group. The emergence agitation level of the patients was evaluated using the Richmond Agitation-Sedation Scale just after extubation and in the post anesthesia care unit (PACU). For postoperative pain evaluation, the Numerical Rating Scale (NRS) was scored (from 0 to 10) every 10 min until the patients were discharged from PACU. RESULTS: EA incidence in the control group was as high as 54.3%, while in the ketamine group it was 8.6% just after extubation (p < 0.001). In the PACU, EA incidence was 28.6% in the control group, while none of the patients had EA in the PACU in the ketamine group (p < 0.001). Male gender, severe pain (NRS >= 5), and smoking were defined as significant risk factors for EA both after extubation and during follow-ups in the PACU (p < 0.001). CONCLUSIONS: Emergence agitation after rhinoplasty is a common complication, likely disturbing operative outcomes in adults. Ketamine at sub-anesthetic doses is highly effective in preventing EA. Further, larger-scale prospective studies are warranted to determine preventive measures for EA development in rhinoplasty.

PMID- 29464386 TI - Clinical Characteristics of Asymmetric Bilateral Gynecomastia: Suggestion of Desirable Surgical Method Based on a Single-Institution Experience. AB - BACKGROUND: Asymmetric bilateral gynecomastia (ABGM) is uncommon, and reports on its characteristics are rare. In the present study, we investigated the clinical characteristics and surgical treatment of ABGM. METHODS: We conducted a retrospective study of 1159 patients with gynecomastia who underwent subcutaneous mastectomy with liposuction at Damsoyu Hospital from January 2014 to February 2016. We then analyzed differences in the characteristics and operative results between two groups of patients: those with asymmetric and symmetric gynecomastia. Asymmetric gynecomastia was defined as gynecomastia meeting both of the following criteria: (1) upon physical examination, the size of the palpable mass below the nipple-areolar complex was twice as large as the smaller one, and (2) upon ultrasonography, the depth of the glandular tissue under the nipple-areolar complex was twice as large as the smaller one. RESULTS: Fifty-four patients were diagnosed with asymmetric gynecomastia. Among them, 51 had ABGM and three had unilateral gynecomastia. In the asymmetric group, more patients had a larger left than right breast (33 patients, 64.7%). The incidence of true-type (entirely glandular) breasts was significantly higher in the asymmetric group (84.3%) than in the symmetric group (p < 0.001). The asymmetry ratios in the asymmetric and symmetric groups were 1.87 +/- 2.07 and 0.20 +/- 0.16, respectively (p < 0.001). CONCLUSION: Bilateral mastectomy provided an acceptable and symmetric cosmetic outcome in patients with ABGM.

PMID- 29464387 TI - Influence of hydrogen bonds on edge-to-face interactions between pyridine molecules. AB - Edge-to-face interactions between two pyridine molecules and the influence of simultaneous hydrogen bonding of one or both of the pyridines to water on those interactions were studied by analyzing data from ab initio calculations. The results show that the edge-to-face interactions of pyridine dimers that are hydrogen bonded to water are generally stronger than those of non-H-bonded pyridine dimers, especially when the donor pyridine forms a hydrogen bond. The binding energy of the most stable edge-to-face interacting H-bonded pyridine dimer is -5.05 kcal/mol, while that for the most stable edge-to-face interacting non-H-bonded pyridine dimer is -3.64 kcal/mol. The interaction energy data obtained in this study cannot be explained solely by the differences in electrostatic potential between pyridine and the pyridine-water dimer. However, the calculated cooperative effect can be predicted using electrostatic potential maps. PMID- 29464388 TI - Simultaneous bone remodeling and surgical decompression of large Sylvian arachnoid cyst. AB - The most common location for intracranial arachnoid cysts is the region of the Sylvian fissure, where they can be found in 49% of cases. Management of these cysts is still quite controversial. We present our surgical technique for the treatment of large Sylvian fissure arachnoid cysts which involves cyst decompression and simultaneous calvarial remodeling. After decreasing cyst size, remodeling of the frontal, temporal, and parietal bones follows. The cyst itself is treated with a cystoperitoneal shunt. In immediate postoperative period, correction of the deformity is observed. The cyst volume is reduced immediately after surgery, and adequate adaptation of the bone is achieved. Our surgical procedure for simultaneous bone remodeling and cyst decompression is a fast, simple, and effective treatment option for patients with large Sylvian fissure arachnoid cysts associated with significant cranial disfigurement. We consider cranial remodeling in case of large arachnoid cyst important not just because of the cosmetic result but also for reducing remaining intracranial space filled with cerebrospinal fluid. It may be an important factor to reduce the risk of intracystic and subdural hemorrhage. It is a widely applicable procedure that does not require special tools and expensive equipment, and yet it can help avoid multiple surgeries and complications tied to them. PMID- 29464389 TI - Patient-reported outcome measures in a pharmacokinetic study with sunitinib, a prospective cohort study. AB - PURPOSE: During treatment with tyrosine kinase inhibitors, such as sunitinib, patients experience treatment and/or disease-related symptoms. Although application of patient-reported outcome measures (PROMs) enhances early recognition of symptoms, early clinical trials are focused on symptom severity objectified by the Common Terminology Criteria for Adverse Events (CTCAE) in order to evaluate drug safety and to determine a personalized and/or safe dosage range. To gain insight into patient-reported symptoms in addition to healthcare professional-reported adverse events (AEs), a substudy was conducted in an ongoing pharmacokinetic-guided sunitinib dosing study. METHODS: In patients for whom sunitinib was considered standard therapy or patients with advanced/metastatic tumors for whom no standard therapy was available, patient reported symptoms and well-being besides healthcare professional-reported AEs were assessed. RESULTS: Twenty-nine patients were included for analysis. Over 50% of them experienced a decreased well-being, caused by symptoms of mild and moderate intensity. Compared to healthcare professionals, all measured symptoms, with the exception of fatigue and vomiting, were reported statistically significantly more often by patients. CONCLUSIONS: Application of PROMs in early clinical trials on personalized or individualized oral targeted anticancer agents is feasible and enhances early recognition of symptom burden due to multiple CTCAE grade 1-2 AEs, just as pro-active symptom management and effect evaluation of interventions performed. Application of PROMs in these trials might be clinically relevant in obtaining dose-limiting toxicities. PMID- 29464390 TI - Bariatric Surgery Prior to Total Joint Arthroplasty, Does it Decrease the Risk of Obesity Related Perioperative Complications? AB - PURPOSE OF REVIEW: The purpose of this review paper is to provide an overview of the relationship between obesity, osteoarthritis, arthroplasty outcomes, and the potential use of bariatric surgery to improve these outcomes. RECENT FINDINGS: Unfortunately, the findings in the currently available literature evaluating the role of bariatric surgery prior to arthroplasty surgery largely rely on retrospective data and their results are somewhat conflicting. Future prospective studies are needed to further evaluate whether or not bariatric surgery prior to arthroplasty surgery may be of benefit for patients. Additional research is needed to identify other methods to minimize complications that obese patients are particularly prone to developing following arthroplasty surgery. PMID- 29464391 TI - Treatment of Pediatric Pulmonary Hypertension. AB - Pulmonary hypertension (PH) is an increasingly recognized problem in children, particularly within tertiary pediatric hospitals. This increase is, in large part, due to ever improving survival among previously fatal conditions, such as extreme prematurity and complicated congenital heart disease. This increased recognition has paralleled burgeoning pharmacologic and interventional PH specific treatment options. Unfortunately, most PH-specific therapies have not been tested in children with rigorous, randomized, controlled trials. As a result, most treatment of PH in children is based upon expert consensus and practitioners' experience. In this article, we highlight some of the current and recent advances in therapies available for children with PH. The role that a Potts shunt may have in ameliorating severe PH in children is highlighted. PMID- 29464392 TI - Posterior subdeltoid and external rotators preserving approach for reduction and fixation of displaced extra-articular fractures of the scapula. AB - BACKGROUND: Operative management of scapular body fractures, when indicated, typically involves extensive exposure through a posterior approach. We present our experience with a deltoid preserving approach that allows excellent exposure of the fracture lines for reduction and fixation while minimizing muscle detachment and overall tissue trauma. TECHNIQUE: Exposure of the scapula was obtained through a posterior incision. The posterior deltoid was exposed and retracted superiorly while the arm was abducted in accordance with Brodsky et al. The scapula was exposed in the interval between infraspinatus and teres minor. PATIENTS AND METHODS: Six patients were treated using this approach and were retrospectively reviewed. All were men with a mean age of 34 years (range 24-45 +/- 6.7 years). The injuries involved two 14-A3.1 and four 14-A3.2 AO/OTA types of fractures. The mean follow-up after surgery was 28 months (range 21-36 +/- 4.93 months). RESULTS: All fractures could be anatomically reduced and healed without compromise. The mean Constant score was 93.8 (range 91-97 +/- 2.13), while range of motion and strength returned to levels equal to the uninjured shoulder. All patients returned to their previous level of activity. We did not observe atrophy of the posterior muscles or hardware complications, and none required hardware removal. CONCLUSION: The deltoid and external rotators preserving posterior approach permitted good visualization of the fractures while allowing reduction and fixation without extensive muscular dissection and provided excellent functional outcomes. We consider that it offers obvious advantages over more aggressive muscle detaching approaches. LEVEL OF EVIDENCE: Therapeutic study, IV. PMID- 29464394 TI - Functional dissection of the three N-terminal general secretory pathway domains and the Walker motifs of the traffic ATPase PilF from Thermus thermophilus. AB - The traffic ATPase PilF of Thermus thermophilus powers pilus assembly as well as uptake of DNA. PilF differs from other traffic ATPases by a triplicated general secretory pathway II, protein E, N-terminal domain (GSPIIABC). We investigated the in vivo and in vitro roles of the GSPII domains, the Walker A motif and a catalytic glutamate by analyzing a set of PilF deletion derivatives and pilF mutants. Here, we report that PilF variants devoid of the first two or all three GSPII domains do not form stable hexamers indicating a role of the triplicated GSPII domain in complex formation and/or stability. A pilFDeltaGSPIIC mutant was significantly impaired in piliation which leads to the conclusion that the GSPIIC domain plays a vital role in pilus assembly. Interestingly, the pilFDeltaGSPIIC mutant was hypertransformable. This suggests that GSPIIC strongly affects transformation efficiency. A pilF?GSPIIA mutant exhibited wild-type piliation but reduced pilus-mediated twitching motility, suggesting that GSPIIA plays a role in pilus dynamics. Furthermore, we report that pilF mutants with a defect in the ATP binding Walker A motif or in the catalytic glutamate residue are defective in piliation and natural transformation. These findings show that both, ATP binding and hydrolysis, are essential for the dual function of PilF in natural transformation and pilus assembly. PMID- 29464395 TI - Temporal Trends of Pediatric Dysphagia in Hospitalized Patients. AB - The objective of this study was to determine temporal trends of dysphagia diagnoses in hospitalized children. This is a retrospective observational study from the 1997-2012 Kids' Inpatient Database (KID) conducted in the setting of weighted hospitalizations in a KID participating center. More than 6 million pediatric admissions were captured in each triennial KID report. Main outcomes included triennial rates of dysphagia diagnosis in hospitalized pediatric patients, and secondary outcomes included rates of dysphagia in premature and low birthweight infants. Dysphagia diagnoses were coded in 5107/6607653 (0.08%) of these admissions in 1997, rising to 27,464/6,675,222 (0.41%) in 2012 (p < 0.001). The portion of these diagnoses in premature neonates has been increasing over time from 162/9551 (1.7%) in 2003 to 1027/27,464 (3.7%) by 2012 (p < 0.001). Similarly, low-birthweight children constituted 40/5107 (0.8%) of dysphagia diagnoses in 1997, a number that increased to 762/27,464 (2.8%) in 2012. Rates of dysphagia are increasing nationally, particularly in premature and low birthweight infants, which may represent an increase alongside other neuroanatomic abnormalities. This growing problem illustrates the need for better data on the comparative efficacy of diagnostic and treatment modalities. PMID- 29464393 TI - Knockdown of STEAP1 inhibits cell growth and induces apoptosis in LNCaP prostate cancer cells counteracting the effect of androgens. AB - Six transmembrane epithelial antigen of the prostate 1 (STEAP1) is overexpressed in numerous types of tumors, especially in prostate cancer. STEAP1 is located in the plasma membrane of epithelial cells and may play an important role in inter- and intracellular communication. Several studies suggest STEAP1 as a potential biomarker and an immunotherapeutic target for prostate cancer. However, the role of STEAP1 in cell proliferation and apoptosis remains unclear. Therefore, the role of STEAP1 in prostate cancer cells proliferation and apoptosis was determined by inducing STEAP1 gene knockdown in LNCaP cells. In addition, the effect of DHT on the proliferation of LNCaP cells knocked down for STEAP1 gene was evaluated. Our results demonstrated that silencing the STEAP1 gene reduces LNCaP cell viability and proliferation, while inducing apoptosis. In addition, we showed that the cellular and molecular effects of STEAP1 gene knockdown may be independent of DHT treatment, and blocking STEAP1 may reveal to be an appropriate strategy to activate apoptosis in cancer cells, as well as to prevent the proliferative and anti-apoptotic effects of DHT in prostate cancer. PMID- 29464396 TI - Phase I study of primary treatment with 5-FU, oxaliplatin, irinotecan, levofolinate, and panitumumab combination chemotherapy in patients with advanced/recurrent colorectal cancer involving the wild-type RAS gene: the JACCRO CC-14 study. AB - BACKGROUND: FOLFOXIRI is now regarded as the chemotherapy regimen that offers the best platform for the treatment of colorectal cancer. However, the safety and efficacy of FOLFOXIRI + panitumumab has not been demonstrated. We conducted a phase I study to determine the recommended dose of FOLFOXIRI + panitumumab as first-line treatment for RAS wild-type metastatic colorectal cancer (mCRC). METHODS: Patients received combination therapy consisting of panitumumab (6 mg/kg on day 1) + FOLFOXIRI [irinotecan (CPT-11), oxaliplatin (L-OHP) 85 mg/m2, and folinate (LV) 200 mg/m2] on day 1, followed by fluorouracil (5-FU) 3200 mg/m2 infused as a 46-h continuous infusion starting on day 1) repeated every 2 weeks as first-line treatment of RAS wild-type mCRC patients. A decrease in CPT-11 dose was planned (started at level 1: CPT-11 165 mg/m2). RESULTS: Seven patients were enrolled, and six were assessed for safety and efficacy. Maximum tolerated dose was not reached at level 1; all patients were treated at these levels. The common Grade 3 or 4 relevant toxicities were diarrhea (50%), hypokalemia (33%) and stomatitis (33%). No treatment-related deaths occurred. Of the six patients assessed four had partial response and the two others had stable disease; hence, the response rate was 66.7% (95% confidence interval 28.9-100%) and the disease control rate was 100%. Time to protocol treatment failure was 7.2 (1.4-7.3) months. CONCLUSION: The FOLFOXIRI + panitumumab chemotherapy regimen was well tolerated by our patients with mCRC and showed promising anti-tumor activity. The recommended phase II dose was determined to be the same as the standard doses of this regimen used worldwide.

AB - Voltage-gated sodium channel (VGSC) beta (beta) subunits have been called the "overachieving" auxiliary ion channel subunit. Indeed, these subunits regulate the trafficking of the sodium channel complex at the plasma membrane and simultaneously tune the voltage-dependent properties of the pore-forming alpha subunit. It is now known that VGSC beta-subunits are capable of similar modulation of multiple isoforms of related voltage-gated potassium channels, suggesting that their abilities extend into the broader voltage-gated channels. The gene family for these single transmembrane immunoglobulin beta-fold proteins extends well beyond the traditional VGSC beta1-beta4 subunit designation, with deep roots into the cell adhesion protein family and myelin-related proteins - where inherited mutations result in a myriad of electrical signaling disorders. Yet, very little is known about how VGSC beta-subunits support protein trafficking pathways, the basis for their modulation of voltage-dependent gating, and, ultimately, their role in shaping neuronal excitability. An evolutionary approach can be useful in yielding new clues to such functions as it provides an unbiased assessment of protein residues, folds, and functions. An approach is described here which indicates the greater emergence of the modern beta-subunits roughly 400 million years ago in the early neurons of Bilateria and bony fish, and the unexpected presence of distant homologues in bacteriophages. Recent structural breakthroughs containing alpha and beta eukaryotic sodium channels containing subunits suggest a novel role for a highly conserved polar contact that occurs within the transmembrane segments. Overall, a mixture of approaches will ultimately advance our understanding of the mechanism for beta-subunit interactions with voltage-sensor containing ion channels and membrane proteins.

AB - Unaffected relatives of individuals with Lynch syndrome can be offered predictive genetic testing to guide surveillance recommendations. The decision-making process of those who decline testing, particularly those who do not attend a clinical genetics service, is poorly understood. We have addressed this gap by interviewing 33 individuals from Lynch syndrome mutation-carrying families, unaffected by cancer, who declined predictive genetic testing. Here, we analyse the data provided by 20 participants who unequivocally declined testing. Those who indicated they did not have enough information to make a decision or intended to undergo testing in the future were excluded. Analysis revealed that few decliners discussed their decision with general practitioners or genetic counsellors. Family members were commonly involved to varying degrees, with participants either (1) making group decisions with family members, (2) feeling persuaded by family members to either accept or decline testing, (3) discussing the test but making their own decision. A minority did not discuss testing with family members while making their decision. This research reveals the health communication activities of an understudied group, those declining predictive testing, and indicates that for many, health professionals play a minor role in the decision compared to family. PMID- 29464400 TI - Monitoring and assessment of urban growth patterns using spatio-temporal built-up area analysis. AB - The identification of spatio-temporal patterns of the urban growth phenomenon has become one of the most significant challenges in monitoring and assessing current and future trends of the urban growth issue. Therefore, spatio-temporal and quantitative techniques should be used hand in hand for a deeper understanding of various aspects of urban growth. The main purpose of this study is to monitor and assess the significant patterns of urban growth in Seremban using a spatio temporal built-up area analysis. The concentric circles approach was used to measure the compactness and dispersion of built-up area by employing Shannon's Entropy method. The spatial directions approach was also utilised to measure the sustainability and speed of development, while the gradient approach was used to measure urban dynamics by employing landscape matrices. The overall results confirm that urban growth in Seremban is dispersed, unbalanced and unsustainable with a rapid speed of regional development. The main contribution of using existing methods with other methods is to provide several spatial and statistical dimensions that can help researchers, decision makers and local authorities understand the trend of growth and its patterns in order to take the appropriate decisions for future urban planning. For example, Shannon's Entropy findings indicate a high value of dispersion between the years 1990 and 2000 and from 2010 to 2016 with a growth rate of approximately 94 and 14%, respectively. Therefore, these results can help and support decision makers to implement alternative urban forms such as the compactness form to achieve an urban form that is more suitable and sustainable. The results of this study confirm the importance of using spatio temporal built-up area and quantitative analysis to protect the sustainability of land use, as well as to improve the urban planning system via the effective monitoring and assessment of urban growth trends and patterns.

AB - Recent studies of noncrystalline HIV-1 capsid protein (CA) assemblies by our laboratory and by Polenova and coworkers (Protein Sci 19:716-730, 2010; J Mol Biol 426:1109-1127, 2014; J Biol Chem 291:13098-13112, 2016; J Am Chem Soc 138:8538-8546, 2016; J Am Chem Soc 138:12029-12032, 2016; J Am Chem Soc 134:6455 6466, 2012; J Am Chem Soc 132:1976-1987, 2010; J Am Chem Soc 135:17793-17803, 2013; Proc Natl Acad Sci USA 112:14617-14622, 2015; J Am Chem Soc 138:14066 14075, 2016) have established the capability of solid state nuclear magnetic resonance (NMR) measurements to provide site-specific structural and dynamical information that is not available from other types of measurements. Nonetheless, the relatively high molecular weight of HIV-1 CA leads to congestion of solid state NMR spectra of fully isotopically labeled assemblies that has been an impediment to further progress. Here we describe an efficient protocol for production of segmentally labeled HIV-1 CA samples in which either the N-terminal domain (NTD) or the C-terminal domain (CTD) is uniformly 15N,13C-labeled. Segmental labeling is achieved by trans-splicing, using the DnaE split intein. Comparisons of two-dimensional solid state NMR spectra of fully labeled and segmentally labeled tubular CA assemblies show substantial improvements in spectral resolution. The molecular structure of HIV-1 assemblies is not significantly perturbed by the single Ser-to-Cys substitution that we introduce between NTD and CTD segments, as required for trans-splicing. PMID- 29464401 TI - Pathological outcomes of transanal versus laparoscopic total mesorectal excision for rectal cancer: a systematic review with meta-analysis. AB - BACKGROUND: Since 2010, comparative studies on transanal and laparoscopic total mesorectal excision (TME) have been published and it remains unclear about the oncological benefit from transanal total mesorectal excision (taTME). METHODS: We have searched English databases to identify all taTME studies published between January 2010 and August 2017. Pathological outcomes included circumferential resection margin (CRM), positive CRM (< 1 M), length of distal resection margin (DRM), positive DRM, quality of mesorectum (complete mesorectum), harvested lymph node, and length of the specimen. Odds ratios (ORs) were calculated for dichotomous outcomes and weighted mean differences (WMDs) for continuous outcomes. RESULTS: We have included ten studies comprising of 762 patients. Compared with laparoscopic TME, taTME had a longer CRM (WMD, 0.833; 95% CI 0.366 1.299; P < 0.001), a lower positive rate of CRM (OR, 0.505; 95% CI 0.258-0.991; P = 0.047), and a longer DRM (WMD, 6.261; 95% CI 1.049-11.472; P = 0.019). There were no significant differences in other pathological outcomes. Both cumulative meta-analysis and sensitivity analysis were unable to detect potential sources of the heterogeneity in DRM. There was no evidence of publication bias. CONCLUSIONS: This meta-analysis revealed that taTME had more advantages on positive CRM, CRM, and DRM compared with laparoscopic TME. Compared with laparoscopic TME, more benefits of taTME on pathological outcomes remained undetected. The current findings are all based on observational studies, RCTs with adequate power are required. PMID- 29464402 TI - Clinical outcomes of minimally invasive treatment for early gastric cancer in patients beyond the indications of endoscopic submucosal dissection. AB - BACKGROUND: Endoscopic submucosal dissection (ESD) with laparoscopic sentinel lymph node dissection (ESN) and endoscopic full-thickness gastric resection with laparoscopic sentinel lymph node dissection (Hybrid-natural orifice transluminal endoscopic surgery, Hybrid-NOTES) are minimally invasive treatment options for early gastric cancer (EGC) beyond the indications of ESD. This study aimed to evaluate the short- and long-term clinical outcomes of ESN and Hybrid-NOTES. METHODS: We retrospectively analyzed patients who had undergone ESN or Hybrid NOTES for EGC from January 2009 to March 2013. A total of 48 patients, including 21 undergoing ESN and 27 undergoing Hybrid-NOTES, were enrolled. All patients had cancer stage T1N0M0, EGC less than 5 cm in size, and suspected submucosal invasion according to imaging or biopsy-proven diffuse-type histology. RESULTS: In ESN and Hybrid-NOTES, the curative resection rates were 76.5% and 90.9% of patients, respectively. In the ESN group, 5 patients underwent an additional gastrectomy (1 for lymph node metastasis (LNM), 3 for surgical complications, and 1 for noncurative resection). In the Hybrid-NOTES group, 6 patients underwent additional gastrectomy, (1 for LNM, 3 for surgical complications, and 2 for noncurative resection). Of the 37 patients who were followed up in the long-term (a median follow-up of 59.8 months), one was found to have liver metastasis after ESN and received palliative chemotherapy. CONCLUSIONS: ESN and Hybrid-NOTES have shown favorable long-term outcomes despite their technical limitations. These methods may be utilized as a bridge between ESD and gastrectomy in cases of EGC with a high risk of LNM beyond the ESD indications. PMID- 29464403 TI - Assessment of snow-glacier melt and rainfall contribution to stream runoff in Baspa Basin, Indian Himalaya. AB - Hydrological regimes of most of the Himalayan river catchments are poorly studied due to sparse hydro-meteorological data. Hence, stream runoff assessment becomes difficult for various socio-industrial activities in the Himalaya. Therefore, an attempt is made in this study to assess the stream runoff of Baspa River in Himachal Pradesh, India, by evaluating the contribution from snow-ice melt and rainfall runoff. The total volume of flow was computed for a period of 15 years, from 2000 to 2014, and validated with the long-term field discharge measurements, obtained from Jaipee Hydropower station (31 degrees 32' 35.53" N, 78 degrees 00' 54.80" E), at Kuppa barrage in the basin. The observations suggest (1) a good correlation (r2 > 0.80) between the modeled runoff and field discharge measurements, and (2) out of the total runoff, 81.2% are produced by snowmelt, 11.4% by rainfall, and 7.4% from ice melt. The catchment receives ~75% of its total runoff in the ablation period (i.e., from May to September). In addition, an early snowmelt is observed in accumulation season during study period, indicating the significant influence of natural and anthropogenic factors on high altitude areas. PMID- 29464404 TI - Assessing and enhancing the utility of low-cost activity and location sensors for exposure studies. AB - Nowadays, the advancement of mobile technology in conjunction with the introduction of the concept of exposome has provided new dynamics to the exposure studies. Since the addressing of health outcomes related to environmental stressors is crucial, the improvement of exposure assessment methodology is of paramount importance. Towards this aim, a pilot study was carried out in the two major cities of Greece (Athens, Thessaloniki), investigating the applicability of commercially available fitness monitors and the Moves App for tracking people's location and activities, as well as for predicting the type of the encountered location, using advanced modeling techniques. Within the frame of the study, 21 individuals were using the Fitbit Flex activity tracker, a temperature logger, and the application Moves App on their smartphones. For the validation of the above equipment, participants were also carrying an Actigraph (activity sensor) and a GPS device. The data collected from Fitbit Flex, the temperature logger, and the GPS (speed) were used as input parameters in an Artificial Neural Network (ANN) model for predicting the type of location. Analysis of the data showed that the Moves App tends to underestimate the daily steps counts in comparison with Fitbit Flex and Actigraph, respectively, while Moves App predicted the movement trajectory of an individual with reasonable accuracy, compared to a dedicated GPS. Finally, the encountered location was successfully predicted by the ANN in most of the cases. PMID- 29464405 TI - The Role of Circulating Tumor DNA in Renal Cell Carcinoma. AB - OPINION STATEMENT: Next-generation sequencing (NGS) of circulating tumor DNA (ctDNA) is a novel technology that can complement tumor tissue NGS and has the potential to influence diagnosis and treatment of both localized and metastatic renal cell carcinoma (mRCC). ctDNA NGS is an attractive alternative to tumor tissue NGS because it circumvents the need for repeated, invasive tissue biopsies while providing a contemporary mutational profile of a patient's tumors. While the role of ctDNA NGS in non-small cell lung cancer and colorectal cancer is well established, studies of ctDNA NGS in mRCC are only hypothesis-generating to date. In the localized RCC setting, ctDNA has demonstrated potential as a surveillance biomarker for disease recurrence. Earlier detection of mRCC, prior to the onset of symptoms, may lead to improved clinical outcomes. NGS of ctDNA in mRCC is even more promising in patients with metastatic disease. The majority of patients with mRCC have detectable ctDNA. Thus, ctDNA could be used to select patients for biomarker-guided clinical trials, such as savolitinib in MET-positive papillary RCC. Furthermore, studies have shown that the mutational profile of mRCC in ctDNA evolves after treatment progression. The most exciting potential role for ctDNA in mRCC is as a predictive biomarker for response to immunotherapy. Studies have shown that tumor mutational burden (TMB) is predictive of response to immune checkpoint inhibitors, and hypermutated ctDNA can act as a surrogate biomarker for TMB and response to immunotherapy. While studies of ctDNA in RCC are still in their infancy, there are many promising roles for ctDNA in localized and metastatic RCC.

AB - Copper is an essential element, but at high concentrations, it is toxic for living organisms. The present study investigated the responses of goldfish, Carassius auratus, to 96 h exposure to 30, 300, or 700 MUg L-1 of copper II chloride (Cu2+). The content of protein carbonyls was higher in kidney (by 158%) after exposure to 700 mg L-1 copper, whereas in gills, liver, and brain, we observed lower content of protein carbonyls after exposure to copper compared with control values. Exposure to copper resulted in increased levels of lipid peroxides in gills (76%) and liver (95-110%) after exposure to 300 and 700 MUg L 1 Cu2+. Low molecular mass thiols were depleted by 23-40% in liver and by 29-67% in kidney in response to copper treatment and can be used as biomarkers toxicity of copper. The activities of primary antioxidant enzymes, superoxide dismutase and catalase, were increased in liver as a result of Cu2+ exposure, whereas in kidney catalase activity was decreased. The activities of glutathione-related enzymes, glutathione peroxidase, glutathione-S-transferase, and glutathione reductase were decreased as a result of copper exposure, but glutathione reductase activity increased by 25-40% in liver. Taken together, these data show that exposure of fish to Cu2+ ions results in the development of low/high intensity oxidative stress reflected in enhanced activities of antioxidant and associated enzymes in different goldfish tissues. PMID- 29464408 TI - Isolation and identification of bovine nasopharyngeal mucosal epithelial cells and establishment of cell models of acute infection by foot-and-mouth disease virus. AB - Foot-and-mouth disease (FMD) commonly occurs via the respiratory tract, and bovine nasopharyngeal mucosal epithelial cells are the primary infection cells in cattle. The aim of the present study was to isolate and culture epithelial cells from the bovine nasopharyngeal mucosa in vitro using a mechanical separation method. The cells were expanded, established in continuous cell culture, and used for immunofluorescence cytochemistry and establishment of infection models. We detected pan-cytokeratin markers of bovine nasopharyngeal mucosal epithelial cells by immunofluorescence. Bovine nasopharyngeal mucosal epithelial cells were then infected with foot-and-mouth disease virus (FMDV) serum type O. RT-PCR demonstrated the successful establishment of acute FMDV infection in the cell models. This infection model provides the basis for clarification of the interaction between FMDV and host bovine nasopharyngeal mucosal epithelial cells in vitro. PMID- 29464410 TI - Simulations of microscopic propulsion of soft elastic bodies. AB - Using simulations that realistically model both hydrodynamic and elastic behavior, we study the motion of a microscopic, driven elastic sphere immersed in water. We first confirm the "jittery" relaxation recently predicted theoretically for an externally driven elastic sphere. The sphere is then divided in two and each section is driven internally with the two sections 180 degrees out of phase. With periodic and perfectly symmetric driving, the elastic sphere spontaneously breaks symmetry and can attain macroscopic average swimming velocities to the right or left, the direction depending only on the initial state. With asymmetric driving the elastic sphere swims in one direction and the maximum speed is obtained with a 1/3:2/3 split. At high drive frequencies close to elastic resonances of the sphere, the motion can be quite efficient. At low drive frequencies the propulsion speed becomes independent of the elastic constants of the sphere and less efficient, but still substantial. Inertia is found to be an important driver of the behavior despite the small size of the spheres. As we model the full three-dimensional elasticity and compressible hydrodynamics, our simulations give not just qualitative indications but quantitative predictions for the motion. PMID- 29464409 TI - Solid-State NMR Investigation of Drug-Excipient Interactions and Phase Behavior in Indomethacin-Eudragit E Amorphous Solid Dispersions. AB - PURPOSE: To investigate the nature of drug-excipient interactions between indomethacin (IMC) and methacrylate copolymer Eudragit(r) E (EE) in the amorphous state, and evaluate the effects on formulation and stability of these amorphous systems. METHODS: Amorphous solid dispersions containing IMC and EE were spray dried with drug loadings from 20% to 90%. PXRD was used to confirm the amorphous nature of the dispersions, and DSC was used to measure glass transition temperatures (Tg). 13C and 15N solid-state NMR was utilized to investigate changes in local structure and protonation state, while 1H T1 and T1rho relaxation measurements were used to probe miscibility and phase behavior of the dispersions. RESULTS: Tg values for IMC-EE solid dispersions showed significant positive deviations from predicted values in the drug loading range of 40-90%, indicating a relatively strong drug-excipient interaction. 15N solid-state NMR exhibited a change in protonation state of the EE basic amine, with two distinct populations for the EE amine at -360.7 ppm (unprotonated) and -344.4 ppm (protonated). Additionally, 1H relaxation measurements showed phase separation at high drug load, indicating an amorphous ionic complex and free IMC-rich phase. PXRD data showed all ASDs up to 90% drug load remained physically stable after 2 years. CONCLUSIONS: 15N solid-state NMR experiments show a change in protonation state of EE, indicating that an ionic complex indeed forms between IMC and EE in amorphous solid dispersions. Phase behavior was determined to exhibit nanoscale phase separation at high drug load between the amorphous ionic complex and excess free IMC. PMID- 29464411 TI - Optimal Human Passive Vestibulo-Ocular Reflex Adaptation Does Not Rely on Passive Training. AB - The vestibulo-ocular reflex (VOR) is the main vision-stabilising system during rapid head movements in humans. A visual-vestibular mismatch stimulus can be used to train or adapt the VOR response because it induces a retinal image slip error signal that drives VOR motor learning. The training context has been shown to affect VOR adaptation. We sought to determine whether active (self-generated) versus passive (externally imposed) head rotation vestibular training would differentially affect adaptation and short-term retention of the active and passive VOR responses. Ten subjects were tested, each over six separate 1.5-h sessions. We compared active versus passive head impulse (transient, rapid head rotations with peak velocity ~ 150 degrees /s) VOR adaptation training lasting 15 min with the VOR gain challenged to increment, starting at unity, by 0.1 every 90 s towards one side only (this adapting side was randomised to be either left or right). The VOR response was tested/measured in darkness at 10-min intervals, 20-min intervals, and two single 60-min interval sessions for 1 h post-training. The training was active or passive for the 10- and 20-min interval sessions, but only active for the two single 60-min interval sessions. The mean VOR response increase due to training was ~ 10 % towards the adapting side versus ~2 % towards the non-adapting side. There was no difference in VOR adaptation and retention between active and passive VOR training. The only factor to affect retention was exposure to a de-adaptation stimulus. These data suggest that active VOR adaptation training can be used to optimally adapt the passive VOR and that adaptation is completely retained over 1 h as long as there is no visual feedback signal driving de-adaptation. PMID- 29464412 TI - Speech Intelligibility Predicted from Neural Entrainment of the Speech Envelope. AB - Speech intelligibility is currently measured by scoring how well a person can identify a speech signal. The results of such behavioral measures reflect neural processing of the speech signal, but are also influenced by language processing, motivation, and memory. Very often, electrophysiological measures of hearing give insight in the neural processing of sound. However, in most methods, non-speech stimuli are used, making it hard to relate the results to behavioral measures of speech intelligibility. The use of natural running speech as a stimulus in electrophysiological measures of hearing is a paradigm shift which allows to bridge the gap between behavioral and electrophysiological measures. Here, by decoding the speech envelope from the electroencephalogram, and correlating it with the stimulus envelope, we demonstrate an electrophysiological measure of neural processing of running speech. We show that behaviorally measured speech intelligibility is strongly correlated with our electrophysiological measure. Our results pave the way towards an objective and automatic way of assessing neural processing of speech presented through auditory prostheses, reducing confounds such as attention and cognitive capabilities. We anticipate that our electrophysiological measure will allow better differential diagnosis of the auditory system, and will allow the development of closed-loop auditory prostheses that automatically adapt to individual users. PMID- 29464413 TI - Influence of the static field on a heavy body in a rotating drum with liquid. AB - The behaviour of a heavy cylindrical body in a rotating horizontal cylindrical cavity filled with viscous liquid is investigated experimentally. Several modes of the body behaviour depending on the rate of the cavity rotation, i.e., the ratio of the centrifugal force of inertia and the gravity, are detected. At a fast rotation rate, the body makes the solid-body rotation, remaining immobile relative to the cavity due to the action of the centrifugal force. In the absence of rotation, under the influence of gravity, the body occupies a position in the lower part of the cavity. At slow uniform rotation rate, the body is dragged by the cavity boundary and shifts to some angle relative to the initial position. With an increase in the rotation rate, the body is repulsed from the cavity boundary and occupies a suspended position, stationary in the laboratory frame, at a certain distance from it. In the suspension regime and the partial repulsion regime, which precedes it, the body performs auto-oscillations that resemble the precession. The flow structures near the suspended cylinder are studied using the PIV method. PMID- 29464414 TI - Metal-Free Half-Metallicity in B-Doped gh-C3N4 Systems. AB - Half-metallicity rising from the s/p electrons has been one of the hot topics in spintronics. Based on the first-principles of calculation, we explore the magnetic properties of the B-doped graphitic heptazine carbon nitride (gh-C3N4) system. Ferromagnetism is observed in the B-doped gh-C3N4 system. Interestingly, its ground state phase (BC1@gh-C3N4) presents a strong half-metal property. Furthermore, the half-metallicity in BC1@gh-C3N4 can sustain up to 5% compressive strain and 1.5% tensile strain. It will lose its half-metallicity, however, when the doping concentration is below 6.25%. Our results show that such a metal-free half-metallic system has promising spintronic applications. PMID- 29464415 TI - Inflammatory Biomarkers During Bacterial Acute Rhinosinusitis. AB - PURPOSE OF REVIEW: Diagnosis of bacterial acute rhinosinusitis is difficult. Several attempts have been made to clarify the diagnostic criteria. Inflammatory biomarkers are easily obtainable variables that could shed light on both the pathophysiology and diagnosis of bacterial acute rhinosinusitis. The purpose of this review article is to assess literature concerning the course of inflammatory biomarkers during acute rhinosinusitis and the use of inflammatory biomarkers in diagnosing bacterial acute rhinosinusitis. RECENT FINDINGS: We included C reactive protein, erythrocyte sedimentation rate, white blood cell counts, procalcitonin, and nasal nitric oxide in this review and found that especially elevated C-reactive protein and erythrocyte sedimentation rate are related to a higher probability of a bacterial cause of acute rhinosinusitis. Still, normal levels of these two biomarkers are quite common as well, or the levels can be heightened even during viral respiratory infection without suspicion of bacterial involvement. Elevated levels of C-reactive protein or erythrocyte sedimentation rate support diagnosis of bacterial acute rhinosinusitis, but due to a lack of sensitivity, they should not be used to screen patients for bacterial acute rhinosinusitis. PMID- 29464416 TI - Sliding friction and contact angle hysteresis of droplets on microhole-structured surfaces. AB - Microstructured surfaces with continuous solid topography have many potential applications in biology and industry. To understand the liquid transport property of microstructured surfaces with continuous solid topography, we studied the sliding behavior of a droplet on microhole-structured surfaces. We found that the sliding friction of the droplet increased with increasing solid area fraction due to enlarged apparent contact area and enhanced contact angle hysteresis. By introducing a correction factor to the modified Cassie-Baxter relation, we proposed an improved theoretical model to better predict the apparent receding contact angle. Our experimental data also revealed that the geometric topology of surface microstructures could affect the sliding friction with microhole decorated surfaces, exhibiting a larger resistance than that for micropillar decorated surfaces. Assisted by optical microscopy, we attributed this topology effect to the continuity and the true total length of the three-phase contact line at the receding edge during the sliding. Our study provides new insights into the liquid sliding behavior on microstructured surfaces with different topologies, which may help better design functional surfaces with special liquid transport properties. PMID- 29464417 TI - Stability of a stationary plane-parallel flow of a ternary fluid between two vertical plates maintained at constant different temperatures. AB - The linear stability of a steady convective flow of a ternary mixture placed between differently heated vertical rigid plates is studied. The applied temperature gradient induces concentration gradients due to the Soret effect. The analysis is done for the case when separation ratios of ternary mixture, i.e., Soret coefficients, have different signs but the net separation ratio is negative. The stability maps in terms of the Grashof number and net separation ratio are obtained and discussed for monotonic and oscillatory modes of instability. The previous results for long-wave instability of a binary mixture were recovered in the limit when one of the Soret coefficients tends to zero. For finite-wavelength perturbations the previous results were extended by discovering the oscillatory instability. PMID- 29464418 TI - Annual costs attributed to atrial fibrillation management: cross-sectional study of primary healthcare electronic records. AB - Atrial fibrillation (AF) is the most common chronic arrhythmia, with increasing healthcare and economic burden and a prevalence which increases with progressive ageing. This study aims to describe overall annual costs per patient for management of non-valvular AF in a primary healthcare (PHC) setting and compare these costs between the groups of patients treated with vitamin K antagonists, antiplatelets or non-treated through a population-based study conducted with electronic health records. We analysed annual costs per person of 19,787 patients in 2012; PHC visits, hospital admissions, AF-related events requiring hospital admission, referrals to secondary specialists, sick leave, diagnostic tests and laboratory tests at PHC level, including INR determinations performed in PHC, and drug therapy. Higher costs of AF management were associated with increasing age, male sex, stroke and bleeding risks, comorbidities and occurrence of events associated to AF. The sensitivity analyses conducted showed that PHC visits and hospitalizations represented the most important part of overall costs for all patients. PMID- 29464419 TI - Light-Induced Covalent Buffer Adducts to Histidine in a Model Protein. AB - PURPOSE: Light is known to induce histidine (His) oxidation and His-His crosslinking in proteins. The crosslinking is resulted from the nucleophilic attack of a His to a photooxidized His from another protein. The goal of this work is to understand if covalent buffer adducts on His residues can be generated by light through similar mechanisms in nucleophilic buffers such as Tris and His. METHODS: A model protein (DNase) was buffer exchanged into nucleophilic buffers before light exposure. Photogenerated products were characterized by tryptic peptide mapping with mass spectrometry (MS) analysis. Several buffer adductions on His residues were identified after light exposure. To understand the influencing factors of such reactions, the levels of adducts were measured for six nucleophilic buffers on all His residues in DNase. RESULTS: The levels of adducts were found to correlate with the solvent accessibility of the His residue. The levels of adducts also correlate with the structure of the nucleophile, especially the steric restrictions of the nucleophile. The levels of adducts can be higher than that of other His photoreaction products, including photooxidation and crosslinking. CONCLUSIONS: In nucleophilic buffers, light can induce covalently-linked adducts to His residues. PMID- 29464420 TI - Dexmedetomidine versus propofol-opioid for sedation in transcatheter aortic valve implantation patients: a retrospective analysis of periprocedural gas exchange and hemodynamic support. AB - PURPOSE: Different sedation regimens have been described for use during transfemoral transcatheter aortic valve implantation (tf-TAVI) for treatment in patients with severe aortic stenosis. The purpose of this study was to compare dexmedetomidine (DEX) with a combination of propofol-opioid (PO) with respect to periprocedural gas exchange and hemodynamic support. METHODS: Data from a cohort of patients sedated with either DEX or PO for tf-TAVI were retrospectively analyzed from a prospectively maintained TAVI registry. Operative risk was determined from comorbidities and risk scores. Periprocedural partial pressure of carbon dioxide (PaCO2) was chosen as the primary endpoint. Other differences in gas exchange, need for catecholamine therapy, the frequency of conversion to general anesthesia, and need for sedative "rescue therapy" (in DEX patients) were secondary endpoints. Inverse probability of treatment weighting (IPTW) was used for analysis to minimize any selection bias. RESULTS: Of the 297 patients (140 PO, 157 DEX) included, the median [interquartile range] periprocedural PaCO2 values of DEX patients were significantly lower than in PO patients (40 [36-45] mmHg vs 44 [40-49] mmHg, respectively; median difference -4 mmHg; 95% confidence interval, -5 to -3 mmHg; P < 0.001). Hypercapnia (PaCO2 > 45 mmHg) was significantly less frequent in DEX patients compared with the PO group (25% vs 42%, respectively; P = 0.005). Vasopressor support was more frequent in the PO group compared with DEX (68% vs 25%, respectively; P < 0.001). Conversion to general anesthesia was not different between groups (9%, PO vs 3%, DEX; P = 0.051). Additional sedatives/opioids were required in 25 (16%) of the DEX patients. CONCLUSIONS: In sedated TAVI patients, DEX was associated with lower PaCO2 values and reduced requirements for vasopressor support, making it a promising alternative to PO for sedation during TAVI.

PMID- 29464421 TI - Two inhibitors of yeast plasma membrane ATPase 1 (ScPma1p): toward the development of novel antifungal therapies. AB - Given that many antifungal medications are susceptible to evolved resistance, there is a need for novel drugs with unique mechanisms of action. Inhibiting the essential proton pump Pma1p, a P-type ATPase, is a potentially effective therapeutic approach that is orthogonal to existing treatments. We identify NSC11668 and hitachimycin as structurally distinct antifungals that inhibit yeast ScPma1p. These compounds provide new opportunities for drug discovery aimed at this important target. PMID- 29464422 TI - Relationship between carotid artery atherosclerosis and bulb geometry. AB - The carotid bifurcation is a common site of atherosclerotic plaque. Plaque development is thought to occur preferentially at geometrically predisposed areas such as arterial branch points. The aim of this study was to investigate the geometric and anatomical variables that contribute to the development of carotid plaque using three-dimensional (3D) ultrasound. Sixty-seven consecutive outpatients referred for elective coronary angiography underwent 3D carotid ultrasound scans for the purpose of carotid plaque quantification. Geometric quantification of the left and right carotid bulbs were performed retrospectively on this study population. Geometric values such as angle, area and length of the carotid bulb and the bifurcation were determined using QLAB software (Philips Healthcare). Plaque volume within the carotid bulb and artery branches was quantified using the stacked contour method. Pearson's correlation and linear regression analysis were used to determine the relationship between anatomical variables and plaque volume. The mean age for the total patient population was 65.9 +/- 11.5 years. Carotid bulb inflow area (BIA) (r = 0.28, p = 0.001), bulb volume (BV) (r = 0.21, p = 0.01) and bifurcation angle (BifA) (r = 0.18, p = 0.04) showed a positive linear relationship with plaque volume. In contrast, internal carotid artery angle (ICAA) (r = - 0.18, p = 0.04) and bulb flare (r = - 0.20, p = 0.02) displayed a negative linear relationship with plaque volume. When adjusting for age and sex, only the BIA remained significant (beta = 0.18, p = 0.04). Geometric variables were identified as potential risk factors associated with plaque volume in the carotid bulb. Further analysis of the evolution of the BIA as well as the relationship to other geometric variables could create a stronger predictive model of atherosclerosis as well as assist in preoperative planning.

AB - Selenium (Se) is an essential trace element for human beings and many other forms of life. Organic selenium from natural foods has greater bioavailability and is safer than inorganic selenium species. In this article, the structural properties and antioxidant activities of a Glycyrrhiza uralensis polysaccharide (GUP) after selenylation modification were investigated. The GUP was extracted by water decoction and ethanol precipitation and purified via protein elimination using the trichloroacetic acid method and column chromatography. The purified product was subsequently modified by the nitric acid-sodium selenite (HNO3-Na2SeO3) method. The selenized GUP (SeGUP) product was characterized by Fourier transform infrared (FT-IR) spectroscopy, and its thermal stability, particle size, and antioxidant activities were investigated. FT-IR analysis indicated that the selenium in SeGUP existed mainly as O-Se-O. The thermal stability and particle size of SeGUP differed significantly from those of GUP. Moreover, compared to GUP, SeGUP exhibited greater antioxidant activities in vitro and in vivo. These results indicate that selenylation modification significantly enhances the antioxidant activity of SeGUP, increasing its potential for application as an antioxidant. Graphical abstract ?. PMID- 29464424 TI - Prevalence and risk factors for CTX-M gram-negative bacteria in hospitalized patients at a tertiary care hospital in Kilimanjaro, Tanzania. AB - Emergence and spread of extended spectrum beta-lactamase (ESBL)-producing gram negative bacteria, mainly due to CTX-M, is a major global public health problem. Patients infected with ESBL-producing gram-negative bacteria have an increased risk of treatment failure and death. We investigated the prevalence and risk factors for CTX-M gram-negative bacteria isolated from clinical specimens of patients hospitalized at a tertiary care hospital in Kilimanjaro, Tanzania. Isolated gram-negative bacteria from inpatients admitted at Kilimanjaro Christian Medical Centre (KCMC) between August 2013 and August 2015 were fully genome sequenced. The prevalence of ESBL-producing gram-negative bacteria was determined based on the presence of blaCTX-M. The odds ratio (OR) and risk factors for ESBL producing gram-negative bacteria due to CTX-M were assessed using logistic regression models. The overall CTX-M prevalence (95% CI) was 13.6% (10.1-18.1). Adjusted for other factors, the OR of CTX-M gram-negative bacteria for patients previously hospitalized was 0.26 (0.08-0.88), p = 0.031; the OR for patients currently on antibiotics was 4.02 (1.29-12.58), p = 0.017; the OR for patients currently on ceftriaxone was 0.14 (0.04-0.46), p = 0.001; and the OR for patients with wound infections was 0.24 (0.09-0.61), p = 0.003. The prevalence of ESBL producing gram-negative bacteria due to CTX-M in this setting is relatively low compared to other previous reports in similar settings. However, to properly stop further spread in the hospital, we recommend setting up a hospital surveillance system that takes full advantage of the available next-generation sequencing facility to routinely screen for all types of bacterial resistance genes. PMID- 29464425 TI - The Interaction Between Child Behavioral Inhibition and Parenting Behaviors: Effects on Internalizing and Externalizing Symptomology. AB - Both child temperament and parenting have been extensively researched as predictors of child outcomes. However, theoretical models suggest that specific combinations of temperament styles and parenting behaviors are better predictors of certain child outcomes such as internalizing and externalizing symptoms than either temperament or parenting alone. The current qualitative review examines the interaction between one childhood temperamental characteristic (child behavioral inhibition) and parenting behaviors, and their subsequent impact on child psychopathology. Specifically, the moderating role of parenting on the relationship between child behavioral inhibition and both internalizing and externalizing psychopathology is examined, and the methodological variations which may contribute to inconsistent findings are explored. Additionally, support for the bidirectional relations between behavioral inhibition and parenting behaviors, as well as for the moderating role of temperament on the relationships between parenting and child outcomes, is briefly discussed. Finally, the clinical applicability of this overall conceptual model, specifically in regard to future research directions and potential clinical interventions, is considered. PMID- 29464426 TI - The impact of historical breastfeeding practices on the incidence of cancer in France in 2015. AB - PURPOSE: The purpose of the study was to estimate the number of new breast cancer cases in France in 2015 attributable to breastfeeding for durations below recommendations (at least 6 months per child), and cases prevented through historical breastfeeding. As a secondary analysis, the corresponding numbers for ovarian cancer were estimated. METHODS: Historical breastfeeding data were obtained from population surveys. Duration of breastfeeding data were obtained from the French Epifane cohort study. Relative risks were obtained from meta analyses, cohort, and case-control studies. Cancer incidence data were obtained from the French Network of Cancer Registries. A 10-year latency period was assumed. RESULTS: Among parous women 25 years of age and older, 14.1% breastfed for at least 6 months per child born before 2006. As a result, 1,712 new breast cancer cases (3.2% of all new breast cancer cases) were attributable to breastfeeding for < 6 months per child, while actual breastfeeding practices prevented 765 breast cancer cases. Furthermore, 411 new ovarian cancer cases (8.6% of all new ovarian cancer cases) may be attributable to breastfeeding for < 6 months per child, with breastfeeding preventing 163 ovarian cancer cases. CONCLUSIONS: The historically low breastfeeding prevalence and duration in France led to numerous avoidable cancer cases. PMID- 29464427 TI - Minority Stressors Associated with Sexual Risk Behaviors and HIV Testing in a U.S. Sample of Transgender Individuals. AB - The majority of published research on transgender health focuses on associations between external minority stressors (e.g., discrimination) and health. Little is known about how internal minority stressors (e.g., identity concealment and expecting rejection) might predict HIV disparities. The current study addresses this gap by examining the association between external and internal minority stressors and sexual risk behaviors and HIV testing history in a sample of 300 transgender adults across the U.S. Transgender-related discrimination and expecting rejection were associated with sexual risk behaviors. When controlling for covariates, none of the minority stressors were associated with HIV testing. Results illustrate how minority stress, both external and internal, may operate uniquely for transgender individuals. PMID- 29464428 TI - Changes in Providers' Self-Efficacy and Intentions to Provide Safer Conception Counseling Over 24 Months. AB - High rates of fertility desires, childbearing and serodiscordant partnerships among people living with HIV (PLHIV) in Uganda underscore the need to promote use of safer conception methods (SCM). Effective SCM exist but few PLHIV benefit from provider-led safer conception counseling (SCC) and comprehensive national SCC guidelines are still lacking. Providers' self-efficacy, intentions and attitudes for SCC impact provision and should inform development of services, but there are no longitudinal studies that assess these important constructs. This study reports on changes in providers' knowledge, attitudes, motivation and confidence to provide SCC among a 24-month observational cohort of Ugandan HIV providers. Compared to baseline, providers evidenced increased awareness of SCM, perceived greater value in providing SCC, saw all SCM but sperm washing as likely to be acceptable to clients, reported consistently high interest in and peer support for providing SCC, and perceived fewer barriers at the 24-month follow-up. Providers' intentions for providing SCC stayed consistently high for all SCM except manual self-insemination which decreased at 24 months. Self-efficacy for providing SCC increased from baseline with the greatest improvement in providers' confidence in advising serodiscordant couples where the man is HIV-infected. Providers consistently cite the lack of established guidelines, training, and their own reluctance to broach the issue with clients as significant barriers to providing SCC. Despite providers being more interested and open to providing SCC than ever, integration of SCC into standard HIV services has not happened. Concerted efforts are needed to address remaining barriers by establishing national SCC guidelines and implementing quality provider training. PMID- 29464429 TI - A Conceptual Model of Dyadic Coordination in HIV Care Engagement Among Couples of Black Men Who Have Sex with Men: A Qualitative Dyadic Analysis. AB - Among Black men who have sex with men (MSM), HIV incidence is disproportionately high and HIV care engagement is disproportionately low. There may be important opportunities to leverage the primary relationship to improve engagement in HIV care and treatment among Black MSM couples. Using dyadic qualitative analysis of semi-structured, one-on-one interviews, we explored dyadic aspects of HIV care engagement among 14 Black MSM couples in which at least one partner was HIV positive and identified as a Black cisgender man. Findings showed that men varied in how involved they were in their HIV-positive partner's care and treatment, and in how they reciprocated their partner's involvement. Patterns of dyadic HIV care engagement supported a conceptual model of dyadic coordination that describes Black MSM relationships in terms of two conceptual dimensions of dyadic HIV care engagement, and guides future intervention designs with Black MSM couples. PMID- 29464431 TI - A SEPSECS mutation in a 23-year-old woman with microcephaly and progressive cerebellar ataxia. AB - Mutations in the SEPSECS gene are associated with pontocerebellar hypoplasia type 2D. Pontocerebellar hypoplasia (PCH) is a heterogeneous group of rare autosomal recessive neurodegenerative disorders, mainly affecting pons and cerebellum. Patients have severe motor and cognitive impairments and often die during infancy. Here, we report a 23-year-old woman with slowly progressive cerebellar ataxia and cognitive impairment, in whom a homozygous missense mutation in the SEPSECS gene (c.1321G>A; p.Gly441Arg) was identified with whole exome sequencing. Our findings underline that defects in selenoprotein synthesis can also result in milder cerebellar atrophy presenting at a later age. PMID- 29464430 TI - HIV Testing and Counseling Among Female Sex Workers: A Systematic Literature Review. AB - HIV testing uptake continues to be low among Female Sex Workers (FSWs). We synthesizes evidence on barriers and facilitators to HIV testing among FSW as well as frequencies of testing, willingness to test, and return rates to collect results. We systematically searched the MEDLINE/PubMed, EMBASE, SCOPUS databases for articles published in English between January 2000 and November 2017. Out of 5036 references screened, we retained 36 papers. The two barriers to HIV testing most commonly reported were financial and time costs-including low income, transportation costs, time constraints, and formal/informal payments-as well as the stigma and discrimination ascribed to HIV positive people and sex workers. Social support facilitated testing with consistently higher uptake amongst married FSWs and women who were encouraged to test by peers and managers. The consistent finding that social support facilitated HIV testing calls for its inclusion into current HIV testing strategies addressed at FSW. PMID- 29464432 TI - Sharpness-Aware Low-Dose CT Denoising Using Conditional Generative Adversarial Network. AB - Low-dose computed tomography (LDCT) has offered tremendous benefits in radiation restricted applications, but the quantum noise as resulted by the insufficient number of photons could potentially harm the diagnostic performance. Current image-based denoising methods tend to produce a blur effect on the final reconstructed results especially in high noise levels. In this paper, a deep learning-based approach was proposed to mitigate this problem. An adversarially trained network and a sharpness detection network were trained to guide the training process. Experiments on both simulated and real dataset show that the results of the proposed method have very small resolution loss and achieves better performance relative to state-of-the-art methods both quantitatively and visually. PMID- 29464433 TI - Optimizing Travel Time to Outpatient Interventional Radiology Procedures in a Multi-Site Hospital System Using a Google Maps Application. AB - The purpose of this study is to determine whether a custom Google Maps application can optimize site selection when scheduling outpatient interventional radiology (IR) procedures within a multi-site hospital system. The Google Maps for Business Application Programming Interface (API) was used to develop an internal web application that uses real-time traffic data to determine estimated travel time (ETT; minutes) and estimated travel distance (ETD; miles) from a patient's home to each a nearby IR facility in our hospital system. Hypothetical patient home addresses based on the 33 cities comprising our institution's catchment area were used to determine the optimal IR site for hypothetical patients traveling from each city based on real-time traffic conditions. For 10/33 (30%) cities, there was discordance between the optimal IR site based on ETT and the optimal IR site based on ETD at non-rush hour time or rush hour time. By choosing to travel to an IR site based on ETT rather than ETD, patients from discordant cities were predicted to save an average of 7.29 min during non-rush hour (p = 0.03), and 28.80 min during rush hour (p < 0.001). Using a custom Google Maps application to schedule outpatients for IR procedures can effectively reduce patient travel time when more than one location providing IR procedures is available within the same hospital system. PMID- 29464434 TI - Vibrational spectra of DNA in the confined interglobular volume of photonic crystal. AB - The impact of confinement of DNA molecules in a limited volume of the cavity of photonic crystals (PC) on the vibrational properties of the DNA molecule and its conformation is studied. According to our preliminary study, the aqueous shell is removed when the DNA molecules are infiltrated into the PC cavities. Raman scattering (RS) DNA marker lines showed a dramatic conformational change of DNA in the PC cavities and the appearance of new unknown conformational states. We observed the enhancement of vibrational modes of DNA in the PC in comparison with free DNA of about tenfold and the absence of vibrational modes in DNA bases in a region of 1450-1700 cm-1. The observed features in the RS spectra of DNA are explained by the impact of confined interglobular volume and strong localization of the electromagnetic field. Namely, FDTD simulations in linear regime demonstrate the localization of light in cavities of PC with an approximately ninefold enhancement of the electric field within the photonic stop-band, which is the main reason for RS amplification. PMID- 29464435 TI - Palliative Care for Movement Disorders. AB - PURPOSE OF REVIEW: While care for patients with movement disorders has traditionally focused on motor symptoms, there is increasing evidence that optimal care for these disorders is more complex both in terms of the spectrum of symptoms experienced by patients (e.g., pain, depression) and the multidimensional needs of patients and their families. Palliative care is an approach to the care of patients and families affected by serious illnesses that seeks to relieve suffering by addressing complex medical symptoms, psychosocial issues, spiritual well-being, and goals of care. While traditionally associated with cancer and hospice, more recent work in palliative care has focused on integrating a palliative care approach from the time of diagnosis for patients with chronic illnesses, including movement disorders. RECENT FINDINGS: Studies of patients with movement disorders and their family caregivers suggest that these patients have significant unmet needs under current models of care, including underrecognition and treatment of non-motor symptoms, inadequate psychosocial support, and suboptimal end-of-life care. We describe how a palliative care approach can empower clinicians, patients, and families to reduce common sources of suffering and optimize quality of life. This field recognizes the importance of primary palliative care (palliative skills useful for any clinician caring for persons caring for serious illness) as a foundation of the palliative care approach and complementary to specialist palliative care. In this article, we will focus on primary palliative care skills for movement disorder specialists including providing a diagnosis and prognosis with compassion, discussing goals of care, complex symptom management, caregiver support, spiritual and emotional well-being, and referral to hospice and specialist palliative care. A palliative care approach complements other efforts in movement disorder care. Research is needed to evaluate and develop therapeutic interventions and models of care applying a palliative care approach. PMID- 29464436 TI - The effect of pH on the dynamics of natural membranes. AB - Pure phospholipids and membrane fragments from bacterial cells living under various conditions were studied against the influence of the surrounding acidity on the internal dynamics. For that we compared mean square displacements extracted from elastic incoherent neutron scattering data, measured both at low and at neutral pH, of the phospholipids 1,2-dimyristoyl-sn-glycero-3 phosphocholine and of samples from neutralophilic and acidophilic micro-organisms (some being hyperthermophilic and others mesophilic). The lipids showed a slight shift in the phase transition temperature of about 4 degrees under pH variation and became slightly more mobile at lower pH. The membrane fragments not used to extreme acidic conditions were significantly more sensitive to variations in the pH values, whereas the acidophilic and -tolerant samples were much less influenced by this parameter. They presented the higher softness at low pH, which was closer to their native condition. Such findings might be a hint for adaptation mechanisms to different acidity conditions. PMID- 29464438 TI - Tregs in SLE: an Update. AB - PURPOSE OF REVIEW: There has been great interest in understanding why T regulatory cells (Tregs) are reduced in number and/or in function in several autoimmune diseases including systemic lupus erythematosus (SLE). Although research has provided some answers, there is still much to learn. RECENT FINDINGS: Recent investigations on the mechanisms responsible for the impairment of the Tregs in SLE have identified relevant abnormalities in cellular and molecular pathways that have been instrumental in the design of studies in animal models and in the development of pilot immunotherapeutic studies in lupus patients. We review the progress made in the field in the last 5 years, discussing the mechanistic studies, together with the preclinical and clinical works that are moving forward the understanding of the physiopathology of Tregs in SLE. PMID- 29464437 TI - Cutaneous Manifestations of Reactions to Biologics. AB - PURPOSE OF REVIEW: The goal of this paper is to review the major adverse cutaneous reactions that have been reported to the most commonly used biologics. RECENT FINDINGS: Anti-TNF agents and immune checkpoint inhibitors have significant, immune-mediated cutaneous manifestations that can necessitate discontinuation. Anti-TNF agents, IL-6 inhibitors, and IL-12/23 inhibitors can paradoxically cause psoriasis flares or unmask previously undiagnosed psoriasis. IL-17 inhibitors are unique in increasing risk for Candida infections. Benign injection site reactions, non-specific rash, cellulitis, and hypersensitivity reactions are relatively common adverse events. A wide variety of cutaneous reactions caused by biologics have been reported, ranging from benign injection site reactions to life-threatening cutaneous reactions necessitating discontinuation of the implicated biologic agent. PMID- 29464441 TI - Left heart pressures can be the key to know the limitation of left ventricular assist device support against progression of aortic insufficiency. AB - Aortic insufficiency (AI) is a worrisome complication under left ventricular assist device (LVAD) support. AI progression causes LVAD-left ventricular (LV) recirculation and can require surgical intervention to the aortic valve. However, the limitations of LVAD support are not well known. Using an animal model of LVAD with AI, the effect of AI progression on hemodynamics and myocardial oxygen metabolism were investigated. Five goats (Saanen 48 +/- 2 kg) underwent centrifugal type LVAD, EVAHEART, implantation. The AI model was established by placing a vena cava filter in the aortic valve. Cardiac dysfunction was induced by continuous beta-blockade (esmolol) infusion. Hemodynamic values and myocardial oxygen extraction ratio (O2ER) were evaluated while changing the degree of AI which was expressed as the flow rate of LVAD-LV recirculation (recirculation rate). Diastolic aortic pressure was decreased with AI progression and correlated negatively with the recirculation rate (p = 0.00055). Systolic left ventricular pressure (LVP) and mean left atrial pressure (LAP) were increased with AI progression and correlated positively with the recirculation rate (p = 0.010, 0.023, respectively). LVP and LAP showed marked exponential increases when the recirculation rate surpassed 40%. O2ER was also increased with AI progression and had a significant positive correlation with the recirculation rate (p = 0.000043). O2ER was increased linearly, with no exponential increase. AI progression made it difficult to reduce the cardiac pressure load, worsening myocardial oxygen metabolism. The exponential increase of left heart pressures could be the key to know the limitation of LVAD support against AI progression. PMID- 29464442 TI - The use of VV-ECMO in patients with drug dependencies. AB - The purpose of this study is to determine the effect of illicit drug and alcohol dependencies on mortality, length of stay, and complications in patients who have been supported with veno-venous extracorporeal membrane oxygenation (VV-ECMO) following respiratory failure not responsive to conventional methods of ventilation. 584 VV-ECMO referrals received at Wythenshawe Hospital were reviewed for evidence of drug dependency. 13 patients were identified as being drug dependent and having undergone treatment with VV-ECMO. A matched cohort of 13 non drug-dependent patients was identified using date of birth, pre-ECMO Murray Score, and primary diagnosis. The outcomes were compared. 19 more complications were found amongst the drug-dependent patients compared with the non-drug dependent cohort (39 vs 20). A mean difference of 1.46 complications per patient was calculated (p = 0.005). Mortality after 180 days was reported in 4 of the drug-dependent patients, compared with one in the matched cohort. Length of stay on ECMO was increased on average by 1.93 days amongst the drug-dependent patients (p = 0.557); however, the sample size was not great enough to achieve statistical significance. Patients with drug dependencies undergoing VV-ECMO have more complications when compared with a cohort of patients with no proven or suspected drug dependencies. Differences in morbidity and mortality were not statistically significant. PMID- 29464443 TI - A visual familiarity account of evidence for orthographic processing in pigeons (Columbia livia): a reply to Scarf, Corballis, Gunturkun, and Colombo (2017). AB - Scarf et al. (Proc Natl Acad Sci 113(40):11272-11276, 2016) demonstrated that pigeons, as with baboons (Grainger et al. in Science 336(6078):245-248, 2012; Ziegler in Psychol Sci. https://doi.org/10.1177/0956797612474322 , 2013), can be trained to display several behavioural hallmarks of human orthographic processing. But, Vokey and Jamieson (Psychol Sci 25(4):991-996, 2014) demonstrated that a standard, autoassociative neural network model of memory applied to pixel maps of the words and nonwords reproduces all of those results. In a subsequent report, Scarf et al. (Anim Cognit 20(5):999-1002, 2017) demonstrated that pigeons can reproduce one more marker of human orthographic processing: the ability to discriminate visually presented four-letter words from their mirror-reversed counterparts (e.g. "LEFT" vs. " "). The current report shows that the model of Vokey and Jamieson (2014) reproduces the results of Scarf et al. (2017) and reinforces the original argument: the recent results thought to support a conclusion of orthographic processing in pigeons and baboons are consistent with but do not force that conclusion. PMID- 29464444 TI - Cuprizone Administration Alters the Iron Metabolism in the Mouse Model of Multiple Sclerosis. AB - Cuprizone (CZ) is a widely used copper chelating agent to develop non-autoimmune animal model of multiple sclerosis, characterized by demyelination of the corpus callosum (CC) and other brain regions. The exact mechanisms of CZ action are still arguable, but it seems that the only affected cells are the mature oligodendrocytes, possibly via metabolic disturbances caused by copper deficiency. During the pathogenesis of multiple sclerosis, high amount of deposited iron can be found throughout the demyelinated areas of the brain in the form of extracellular iron deposits and intracellularly accumulated iron in microglia. In the present study, we used the accepted experimental model of 0.2% CZ-containing diet with standard iron concentration to induce demyelination in the brain of C57BL/6 mice. Our aim was to examine the changes of iron homeostasis in the CC and as a part of the systemic iron regulation, in the liver. Our data showed that CZ treatment changed the iron metabolism of both tissues; however, it had more impact on the liver. Besides the alterations in the expressions of iron storage and import proteins, we detected reduced serum iron concentration and iron stores in the liver, together with elevated hepcidin levels and feasible disturbances in the Fe-S cluster biosynthesis. Our results revealed that the CZ containing diet influences the systemic iron metabolism in mice, particularly the iron homeostasis of the liver. This inadequate systemic iron regulation may affect the iron homeostasis of the brain, eventually indicating a relationship among CZ treatment, iron metabolism, and neurodegeneration. PMID- 29464445 TI - Night shift work and breast cancer: a pooled analysis of population-based case control studies with complete work history. AB - Night shift work has been suspected to increase breast cancer risk but epidemiological studies have been inconsistent due to heterogeneous assessment of exposure to night work. To overcome this limitation, we pooled data of five population-based case-control studies from Australia, Canada, France, Germany, and Spain into a single harmonized dataset using a common definition of night work including 6093 breast cancer cases and 6933 population controls. The odds ratio for breast cancer in women who ever worked at night for at least 3 h between midnight and 5 a.m. as compared to never night workers was 1.12 (95% CI 1.00-1.25). Among pre-menopausal women, this odds ratio was 1.26 [1.06-1.51], increasing to 1.36 [1.07-1.74] for night shifts >= 10 h, 1.80 [1.20-2.71] for work >= 3 nights/week, and 2.55 [1.03-6.30] for both duration of night work >= 10 years and exposure intensity >= 3 nights/week. Breast cancer risk in pre menopausal women was higher in current or recent night workers (OR = 1.41 [1.06 1.88]) than in those who had stopped night work more than 2 years ago. Breast cancer in post-menopausal women was not associated with night work whatever the exposure metric. The increase in risk was restricted to ER+ tumors, particularly those who were both ER+ and HER2+ . These results support the hypothesis that night shift work increases the risk of breast cancer in pre-menopausal women, particularly those with high intensity and long duration of exposure. Risk difference between pre- and post-menopausal women deserves further scrutiny. PMID- 29464446 TI - Supportive therapy in gastroenteropancreatic neuroendocrine tumors: Often forgotten but important. AB - Neuroendocrine tumors (NETs) are a group of rare and heterogeneous malignancies that can develop in various organs. A significant number of gastroenteropancreatic neuroendocrine tumours (GEP-NETs) is functionally active and presents with symptoms related to the secretion of biologically active substances, leading to the development of distinct clinical syndromes. There are various therapeutic approaches for GEP-NETs, including curative surgery, palliative surgery, local-ablative and loco-regional therapies as well as systemic therapeutic options including peptide receptor radionuclide therapy, cytotoxic therapy, and molecularly targeted therapies. Specific supportive therapy of patients with NETs includes management or prevention of hormone related clinical syndromes and paraneoplastic states. Supportive therapy plays a key role in NET treatment. Supportive therapy includes debulking surgery and interventional radiologic techniques to reduce tumour bulk or load, as well as systemic medical treatment options to manage or prevent hypersecretion syndromes and treatment-related side effects. Supportive therapies are a type of of comprehensive treatment addressing the patient as a whole person throughout the process of NET treatment. Therefore, supportive therapy also encompasses psychosocial support, expert nursing, nutritional support and management of cancer related pain. PMID- 29464447 TI - Pathogenesis of Skin Injury of Systemic Lupus Erythematosus. AB - PURPOSE OF REVIEW: The second most common clinical expression in lupus patients is skin damage that the pathogenesis remains unclear. We discuss the role of pathological factors in the development of skin damage in SLE. RECENT FINDINGS: Skin deposited IgG is a crucial pathologic factor in the development of skin damage in SLE. Macrophages and signaling of TNFalpha/TNFR1 and IFN/IFNR play an important role in the skin injury of SLE. The intracellular molecules including Syk and calcium/calmodulin 4 and NFAT are involved in the manifestation of skin damage in lupus-prone mice. UV is the most typical environmental factor to trigger skin injury in areas of IgG deposition in SLE. These evidences indicate that skin deposited IgG is a crucial pathological factor to trigger skin lesions in SLE and blockade of IgG signaling may be effective target against skin injury of SLE. PMID- 29464449 TI - Are Women's Orgasms Hindered by Phallocentric Imperatives? AB - Women who have sex with women (WSW) are more likely to report experiencing an orgasm during partnered sex, compared to women who have sex with men (WSM). We investigated whether this difference can be partially accounted for by phallocentric imperatives-gendered sexual scripts that prioritize men's sexual experience. For example, these imperatives emphasize vaginal-penile intercourse (i.e., the coital imperative) and men's physical pleasure (i.e., the male orgasm imperative). We reasoned that a larger variety of sexual behaviors indicates less adherence to the coital imperative and that more self-oriented orgasm goals for women indicate less adherence to the male orgasm imperative. Consistent with previous work, we expected WSW to report higher rates of orgasm than WSM when taking frequency of sex into account. We also hypothesized that this difference in orgasm rates would dissipate when controlling for variety of sexual behavior and women's self-oriented orgasm goals. In a sample of 1988 WSM and 308 WSW, we found that WSW were 1.33 times (p < .001) more likely to report experiencing an orgasm than WSM, controlling for frequency of sex. This incidence rate ratio was reduced to 1.16 (p < .001) after taking into account variety of sexual behavior and self-oriented orgasm goals. Our findings indicate that certain sexual scripts (e.g., phallocentric imperatives) help explain the orgasm discrepancy between WSW and WSM. We discuss masturbation as another male-centered practice that may be relevant to this gap, as well as implications for intervention and future research. PMID- 29464448 TI - Development and validation of an algorithm to identify drug-induced anaphylaxis in the Beijing Pharmacovigilance Database. AB - Background Pharmacovigilance databases are utilized to identify serious adverse drug events (ADEs). In China, very few studies have evaluated the validity of using pharmacovigilance databases to identify drug-induced anaphylaxis (DIA). Objective We aimed to develop and validate an algorithm to identify DIA using the Beijing Pharmacovigilance Database (BPD). Setting ADEs from the BPD mainly spontaneously reported from 94 hospitals in Beijing, China. Method Using the diagnoses, we developed an algorithm to identify potential DIAs from the BPD between January 2004 and December 2014. A sample of 500 patients was randomly selected for chart abstraction. Two physician adjudicators assessed whether DIA occurred using the published clinical criteria as the gold standard. Main outcome measure Positive predictive values (PPVs) and 95% confidence intervals of the algorithm and algorithm criteria components were calculated. Results 500 patients (53.2% female; the mean age 48.2 years) with potential DIA were selected using the algorithm. 444 were adjudicated as having anaphylaxis by physicians. The PPV of the overall algorithm was 88.8% (95% CI 86.0-91.6%). PPV for the algorithm only using specific diagnoses of "anaphylactic shock", "anaphylactic reaction", and "anaphylactoid reaction [severe]" was 89.6% (95% CI 86.6-92.4%); this partial algorithm identified 387 (87.2%) DIAs. The diagnosis that identified the most DIAs (83.8%) was "anaphylactic shock", with a PPV of 91.6% (95% CI 88.9-94.3%). Conclusion The overall algorithm identified a greater number of DIAs than the algorithm that only used specific diagnoses; however, its PPV was slightly lower. We were able to identify DIAs with the algorithm we developed.

PMID- 29464451 TI - The Co-Occurrence of Asexuality and Self-Reported Post-Traumatic Stress Disorder Diagnosis and Sexual Trauma Within the Past 12 Months Among U.S. College Students. AB - An increasing number of individuals identify as asexual. It is important to understand the relationship between a diagnosis of post-traumatic stress disorder or a history of sexual trauma co-occurs with asexual identity. We aimed to assess whether identification as asexual was associated with greater likelihood for self reported PTSD diagnosis and history of sexual trauma within the past 12 months. Secondary data analysis was undertaken of a cross-sectional survey of 33,385 U.S. college students (12,148 male, 21,237 female), including 228 self-identified asexual individuals (31 male, 197 female), who completed the 2015-2016 Healthy Minds Study. Measures included assessment of self-report of prior professional diagnosis of PTSD and self-report of prior sexual trauma in the past year. Among non-asexual participants, 1.9% self-reported a diagnosis of PTSD and 2.4% reported a history of sexual trauma in the past 12 months. Among the group identified as asexual, 6.6% self-reported a diagnosis of PTSD and 3.5% reported a history of sexual assault in the past 12 months. Individuals who identified as asexual were more likely to report a diagnosis of PTSD (OR 4.44; 95% CI 2.32, 8.50) and sexual trauma within the past 12 months (OR 2.52; 95% CI 1.20, 5.27), compared to non-asexual individuals. These differences persisted after including sex of the participants in the model, and the interaction between asexual identification and sex was not significant in either case. Asexual identity was associated with greater likelihood of reported PTSD diagnosis and reported sexual trauma within the past 12 months. Implications for future research on asexuality are discussed. PMID- 29464452 TI - Implicit and Explicit Associations with Erotic Stimuli in Women with and Without Sexual Problems. AB - Conceptual models of sexual functioning have suggested a major role for implicit cognitive processing in sexual functioning. The present study aimed to investigate implicit and explicit cognition in sexual functioning in women. Gynecological patients with (N = 38) and without self-reported sexual problems (N = 41) were compared. Participants performed two Single-Target Implicit Association Tests (ST-IAT), measuring the implicit association of visual erotic stimuli with attributes representing, respectively, valence and motivation. Participants also rated the erotic pictures that were shown in the ST-IATs on the dimensions of valence, attractiveness, and sexual excitement, to assess their explicit associations with these erotic stimuli. Participants completed the Female Sexual Functioning Index and the Female Sexual Distress Scale for continuous measures of sexual functioning, and the Hospital Anxiety and Depression Scale to assess depressive symptoms. Compared to nonsymptomatic women, women with sexual problems were found to show more negative implicit associations of erotic stimuli with wanting (implicit sexual motivation). Across both groups, stronger implicit associations of erotic stimuli with wanting predicted higher level of sexual functioning. More positive explicit ratings of erotic stimuli predicted lower level of sexual distress across both groups. PMID- 29464453 TI - Gender Expression and Mental Health in Black South African Men Who Have Sex with Men: Further Explorations of Unexpected Findings. AB - Unlike studies conducted in Western countries, two studies among Black South African men who have sex with men (MSM) found no support for the association between gender nonconformity and mental distress, even though gender nonconforming men experienced more discrimination and discrimination was associated with mental distress (Cook, Sandfort, Nel, & Rich, 2013; Sandfort, Bos, Knox, & Reddy, 2016). In Sandfort et al., gender nonconformity was assessed as a continuous variable, validated by comparing scores between a categorical assessment of gender presentation (masculine, feminine, no preference). Using the same dataset, we further explored this topic by (1) testing differences between gender expression groups in sexual minority stressors, resilience factors, and mental distress; (2) testing whether the impact of elevated discrimination in the feminine group was counterbalanced by lower scores on other stressors or higher scores on resilience factors; and (3) exploring whether relationships of stressors and resilience factors with mental distress varied between gender expression groups. Controlling for demographics, we found several differences between the gender expression groups in the stressors and resilience factors, but not in mental distress. We found no support for the idea that the lack of differences in mental distress between the gender expression groups was a consequence of factors working in opposite directions. However, internalized homophobia had a differential impact on depression in feminine men compared to masculine men. In our discussion of these findings, we explored the meaning of our participants' self-categorization as it might relate to gender instead of sexual identities. PMID- 29464454 TI - Never Been Kissed: Correlates of Lifetime Kissing Status in U.S. University Students. AB - Kissing a partner occurs relatively early during adolescence. Thus, young adults who have never kissed are off-time from their peers. Substantial exploration in the areas of identity and intimacy occur during this period, and kissing may fulfill both of these functions, addressing autonomy and relatedness motives for sexual behaviors. We examined the prevalence and personal, contextual, and adjustment/health predictors of delayed onset of kissing. An ethnically and racially diverse sample of traditionally aged first year university students (N = 738; 50.7% female) completed online surveys. Only 14.2% of young adults had never kissed a partner on the lips. Compared to their peers who had kissed partners, young adults who had never kissed were more likely to be Asian-American, less likely to be in a romantic relationship, were less extraverted, were more likely to be in the Honors College, and drank alcohol less frequently. In bivariate models but not the multivariate model, young adults who had never kissed were more neurotic, had mothers who were less facilitating of independence, and had lower self-esteem. Findings inform understanding of normative sexuality development, and inform future research on normative and off-time sexual behaviors in young adulthood. PMID- 29464455 TI - "And Then Break the Cliche": Understanding and Addressing HIV Vulnerability Through Development of an HIV Prevention Telenovela with Men Who Have Sex with Men and Transwomen in Lima, Peru. AB - HIV and other sexually transmitted infections (STIs) continue to affect men who have sex with men (MSM) and transgender women (TW) in Peru at disproportionately high rates. The ineffectiveness of traditional prevention strategies may be due to the disconnect between health promotion messages and community-level understandings of sexual cultures. We conducted 15 workshops with MSM and TW to develop a community-based sexual health intervention. Intervention development consisted of focus groups and scenic improvisation to identify sexual scripts for an HIV prevention telenovela, or Spanish soap opera. Workshops were stratified by self-reported socioeconomic status, sexual orientation, and gender identity: (1) low-income MSM (n = 9); (2) middle/high-income MSM (n = 6); and (3) TW (n = 8). Employing a conceptual model based on sexual scripts and critical consciousness theories, this paper reports on three themes identified during the telenovela development process as participants sought to "rescript" social and sexual stereotypes associated with HIV-related vulnerability: (1) management of MSM and TW social identities at the intersection of socioeconomic status, sexuality, and gender performance; (2) social constructions of gender and/or sexual role and perceived and actual HIV/STI risk(s) within sexual partnership interactions; and (3) idealized and actual sexual scripts in the negotiation of safer sex practices between MSM/TW and their partners. These findings are key to reframing existing prevention strategies that fail to effectively engage poorly defined "high-risk populations." Leveraging community-based expertise, the results provide an alternative to the static transfer of information through expert-patient interactions in didactic sessions commonly used in HIV prevention interventions among MSM and TW. PMID- 29464456 TI - Application of validity theory and methodology to patient-reported outcome measures (PROMs): building an argument for validity. AB - BACKGROUND: Data from subjective patient-reported outcome measures (PROMs) are now being used in the health sector to make or support decisions about individuals, groups and populations. Contemporary validity theorists define validity not as a statistical property of the test but as the extent to which empirical evidence supports the interpretation of test scores for an intended use. However, validity testing theory and methodology are rarely evident in the PROM validation literature. Application of this theory and methodology would provide structure for comprehensive validation planning to support improved PROM development and sound arguments for the validity of PROM score interpretation and use in each new context. OBJECTIVE: This paper proposes the application of contemporary validity theory and methodology to PROM validity testing. ILLUSTRATIVE EXAMPLE: The validity testing principles will be applied to a hypothetical case study with a focus on the interpretation and use of scores from a translated PROM that measures health literacy (the Health Literacy Questionnaire or HLQ). DISCUSSION: Although robust psychometric properties of a PROM are a pre-condition to its use, a PROM's validity lies in the sound argument that a network of empirical evidence supports the intended interpretation and use of PROM scores for decision making in a particular context. The health sector is yet to apply contemporary theory and methodology to PROM development and validation. The theoretical and methodological processes in this paper are offered as an advancement of the theory and practice of PROM validity testing in the health sector. PMID- 29464457 TI - Cloning and characterization of the human lactoferrin receptor gene promoter. AB - Lactoferrin (Lf) is a major protein in human milk. Multiple biological functions of Lf are postulated to be mediated by a Lf receptor (LfR). The Lf receptor (LfR) plays an important role in absorption of Lf and Lf-bound iron by intestinal epithelial cells. Here, we cloned and characterized the promoter from a ~ 3.1 kb 5'-flanking region of the human LfR gene. Neither a TATA box nor a CCAAT box is found at the typical positions. The transcription start site was identified as 298 bp upstream of the translation start codon (+ 1) by 5' RLM-RACE. A series of deletions of 5'-flanking sequences of the human LfR gene were cloned into a promoter-less pGL3 luciferase reporter and transiently transfected into an intestinal enterocyte model (Caco-2 cells). A fragment of - 299/+ 63 elicited the maximal promoter activity in transfected Caco-2 cells, suggesting that functional transcription factor binding sites appear in the region of - 299/+ 63. Bioinformatics analysis indicates that the - 299/+ 63 fragment contains two putative Sp1 binding sites. The promoter activity was significantly decreased when the Sp1 binding sites were mutated by site-directed mutagenesis. Additionally, the promoter activity was dramatically inhibited by treating cells with an Sp1 inhibitor. Binding of Sp1 to the promoter was confirmed by EMSA. Moreover, after Sp1 expression was significantly suppressed by RNA interference, LfR was significantly decreased at both RNA and protein levels. In conclusion, the LfR gene promoter contains downstream core promoter elements, and the Sp1 binding sites play critical roles in transcriptional regulation of the LfR gene. PMID- 29464458 TI - PFO closure for secondary stroke prevention: is the discussion closed? AB - Three previous reports of PFO closure for secondary stroke prevention failed to find any significant benefit. Recently however, three conflicting reports were published suggesting a benefit in select patients. Although we are enthusiastic for PFO closure in appropriate patients, caution is warranted in the extrapolation of this data and the application of this intervention to broader patient groups. Only small minorities of stroke patients are likely to benefit from PFO closure, the intervention has a notable complication rate, and it has not been compared against modern anticoagulation options. Clinicians should consider all of these points as discussions around PFO closure are likely to become more and more common going forward. PMID- 29464459 TI - A Diaper Pad for Diaper-Based Urine Collection and Colorimetric Screening of Urinary Biomarkers. AB - The high prevalence of urinary tract infection in aging adults is a challenging aspect of geriatric care. Incontinence and cognitive/functional impairment make collection of urine samples difficult and often require either catheterization for sample collection, which is a risk factor for infections, or more lenient criteria for initiating antibiotic treatment. We report the development of a diaper inlay with absorbent materials, superabsorbent polymer-based valve and chemical reaction pads for rapid screening of urinary tract infection of incontinent diaper-wearing elderly receivers of home care services. The developed diaper inlay was capable of collecting, isolating, analyzing samples and retaining results > 8 h. The diaper inlay can therefore be compatible with the diaper changing routines of nurses in home care services, without requiring much time or effort. A nurse can insert a diaper inlay in a diaper and the results can be recorded during a later diaper change. Although the research focuses on tools for home care services, the nursing home sector has similar problems and may benefit from technological development for rapid screening to avoid unnecessary catheterization and overuse of antibiotics. PMID- 29464460 TI - Effects of Hollow Fiber Membrane Oscillation on an Artificial Lung. AB - Gas transfer through hollow fiber membranes (HFMs) can be increased via fiber oscillation. Prior work, however, does not directly translate to present-day, full-scale artificial lungs. This in vitro study characterized the effects of HFM oscillations on oxygenation and hemolysis for a pediatric-sized HFM bundle. Effects of oscillation stroke length (2-10 mm) and frequency (1-25 Hz) on oxygen transfer were measured according to established standards. The normalized index of hemolysis was measured for select conditions. All measurements were performed at a 2.5 L min-1 blood flow rate. A lumped parameter model was used to predict oscillation-induced blood flow and elucidate the effects of system parameters on oxygenation. Oxygen transfer increased during oscillations, reaching a maximum oxygenation efficiency of 510 mL min-1 m-2 (97% enhancement relative to no oscillation). Enhancement magnitudes matched well with model-predicted trends and were dependent on stroke length, frequency, and physical system parameters. A 40% oxygenation enhancement was achieved without significant hemolysis increase. At a constant enhancement magnitude, a larger oscillation frequency resulted in increased hemolysis. In conclusion, HFM oscillation is a feasible approach to increasing artificial lung gas transfer efficiency. The optimal design for maximizing efficiency at small fiber displacements should minimize bundle resistance and housing compliance. PMID- 29464461 TI - Tactile Feedback can be Used to Redistribute Flexion Motion Across Spine Motion Segments. AB - This experiment investigates the efficacy of tactile feedback in affecting changes to dynamic spine movements. A sample of (n = 24) young, healthy males were assessed while completing targeted spine flexion movements with instruction to minimize stretching of the skin beneath an applied tactile stimulus (liquid bandage). Localized tactile stimuli were placed bilaterally at either lumbar (L4), lower thoracic (T10) or upper thoracic (T4) levels. Results demonstrate that localized tactile feedback elicited a re-distribution of spine flexion movement across spine sub-sections (e.g. lumbar vs. thoracic) and intervertebral segments (e.g. C7/T1 through L5/S1). Further, tactile feedback successfully limited the magnitude of end-range flexion, but did not limit functional mid range spine flexion. Finally, tactile feedback located in the lower thoracic region (T10) increased thoracic flexion variability; however, tactile feedback located at the T4 and L4 regions had no significant effect on movement variability. These findings provide evidence that spine neuromuscular control patterns can be altered using simple tactile stimuli. In terms of low back injury prevention and/or rehabilitation, the tactile feedback investigated here has apparent utility in limiting recognized mechanical risk factors for low back injury; specifically, the local incidence of flexion at specific spine levels, and the incidence of end-range flexion. PMID- 29464462 TI - Gestational and lactational exposure to dichlorinated bisphenol A induces early alterations of hepatic lipid composition in mice. AB - OBJECTIVE: Using non-invasive magnetic resonance (MR) techniques and a histological approach, we assessed the outcomes of perinatal exposure at a low dose of 3,3'-DCBPA (2-chloro-4-[1-(3-chloro-4-hydroxyphenyl)-1 methylethyl]phenol) and/or 3,5-DCBPA (2,6-dichloro-4-[1-(4-hydroxyphenyl)-1 methylethyl]phenol) on mice livers. MATERIALS AND METHODS: Fertilized female Swiss mice were injected intraperitoneally during gestation and lactation with either vehicle control, 20 MUg/kg/day of BPA, 3,5-DCBPA, 3,3'-DCBPA or a mixture (mix-DCBPA). Complementary methods were used to evaluate, in male and female pups, (1) liver structure by texture analysis of images obtained through MR imaging (MRI) and histology, (2) hepatic lipid composition through in vivo 1H MR spectroscopy (1H MRS). RESULTS: Principal component analysis of texture parameters showed no structural modification of the liver with BPA and DCBPA treatments. Accordingly, no hepatic microvesicular steatosis was observed through hematoxylin-eosin staining. Compared to control, MRS revealed no difference in lipid composition for BPA, 3,5-DCBPA or 3,3'-DCBPA groups. However, MRS detected a significant increase in the mix-DCBPA groups for the saturated component of fatty acids (FA), total unsaturated FA bond index and polyunsaturated FA bond index. CONCLUSION: Prior to any structural changes, polyunsaturated fatty acids significantly increased in young male and female mice exposed perinatally at a low dose to a mixture of dichlorinated BPA. PMID- 29464463 TI - The impact of fibre orientation on T1-relaxation and apparent tissue water content in white matter. AB - OBJECTIVE: Recent MRI studies have shown that the orientation of nerve fibres relative to the main magnetic field affects the R2*(= 1/T2*) relaxation rate in white matter (WM) structures. The underlying physical causes have been discussed in several studies but are still not completely understood. However, understanding these effects in detail is of great importance since this might serve as a basis for the development of new diagnostic tools and/or improve quantitative susceptibility mapping techniques. Therefore, in addition to the known angular dependence of R2*, the current study investigates the relationship between fibre orientation and the longitudinal relaxation rate, R1 (= 1/T1), as well as the apparent water content. MATERIALS AND METHODS: For a group of 16 healthy subjects, a series of gradient echo, echo-planar and diffusion weighted images were acquired at 3T from which the decay rates, the apparent water content and the diffusion direction were reconstructed. The diffusion weighted data were used to determine the angle between the principle fibre direction and the main magnetic field to examine the angular dependence of R1 and apparent water content. RESULTS: The obtained results demonstrate that both parameters depend on the fibre orientation and exhibit a positive correlation with the angle between fibre direction and main magnetic field. CONCLUSION: These observations could be helpful to improve and/or constrain existing biophysical models of brain microstructure by imposing additional constraints resulting from the observed angular dependence R1 and apparent water content in white matter. PMID- 29464464 TI - Pazopanib-related tumor lysis syndrome in metastatic clear cell renal cell carcinoma: a case report. AB - Introduction Tumor lysis syndrome (TLS) is a life-threatening emergency caused by rapid cell death as a result of anti-tumor therapy. In the era of targeted therapy it has increasingly been observed in solid malignancies such as hepatocellular carcinoma (HCC) and renal cell carcinoma (RCC). Case We describe the case of a 58-year old man with the medical history of a memorial sloan kettering cancer centre (MSKCC) poor prognosis metastasized clear cell renal cell carcinoma (mRCC) who developed TLS within six days after initiating therapy with the tyrosine kinase inhibitor (TKI) pazopanib. Discussion The pharmacokinetics and pharmacodynamics of pazopanib are complex and characterized by a non-linear and time-dependent bioavailability. Pazopanib is almost completely bound to serum albumin (>99.9%). In this presented case, a low serum albumin (26 g/L) might have led to a higher free fraction of pazopanib, which could have resulted in more toxicity. Also, pazopanib is metabolised by the CYP3A4 isoform of the cytochrome P450 group. Low quantities of this enzyme may lead to an impaired and prolonged breakdown of the drug. Conclusion As far as we know this is the first report on pazopanib induced TLS. We advise further research in order to identify the exact mechanism behind TKI-induced TLS and the patients at risk of developing TLS. PMID- 29464465 TI - The concomitant use of lapatinib and paracetamol - the risk of interaction. AB - Lapatinib is a tyrosine kinase inhibitor used for the treatment of breast cancer. Paracetamol is an analgesic commonly applied to patients with mild or moderate pain and fever. Cancer patients are polymedicated, which involves high risk of drug interactions during therapy. The aim of the study was to assess the interaction between lapatinib and paracetamol in rats. The rats were divided into three groups of eight animals in each. One group received lapatinib + paracetamol (IL + PA), another group received lapatinib (IIL), whereas the last group received paracetamol (IIIPA). A single dose of lapatinib (100 mg/kg b.w.) and paracetamol (100 mg/kg b.w.) was administered orally. Plasma concentrations of lapatinib, paracetamol and its metabolites - glucuronide and sulphate, were measured with the validated HPLC-MS/MS method and HPLC-UV method, respectively. The pharmacokinetic parameters of both drugs were calculated using non compartmental methods. The co-administration of lapatinib and paracetamol increased the area under the plasma concentration-time curve (AUC) and the maximum concentration (Cmax) of lapatinib by 239.6% (p = 0.0030) and 184% (p = 0.0011), respectively. Lapatinib decreased the paracetamol AUC0-infinity by 48.8% and Cmax by 55.7%. In the IL + PA group the Cmax of paracetamol glucuronide was reduced, whereas the Cmax of paracetamol sulphate was higher than in the IIIPA group. Paracetamol significantly affected the enhanced plasma exposure of lapatinib. Additionally, lapatinib reduced the concentrations of paracetamol. The co-administration of lapatinib decreased the paracetamol glucuronidation but increased the sulphation. The findings of this study may be of clinical relevance to patients requiring analgesic therapy. PMID- 29464466 TI - WhichP450: a multi-class categorical model to predict the major metabolising CYP450 isoform for a compound. AB - In the development of novel pharmaceuticals, the knowledge of how many, and which, Cytochrome P450 isoforms are involved in the phase I metabolism of a compound is important. Potential problems can arise if a compound is metabolised predominantly by a single isoform in terms of drug-drug interactions or genetic polymorphisms that would lead to variations in exposure in the general population. Combined with models of regioselectivities of metabolism by each isoform, such a model would also aid in the prediction of the metabolites likely to be formed by P450-mediated metabolism. We describe the generation of a multi class random forest model to predict which, out of a list of the seven leading Cytochrome P450 isoforms, would be the major metabolising isoforms for a novel compound. The model has a 76% success rate with a top-1 criterion and an 88% success rate for a top-2 criterion and shows significant enrichment over randomised models. PMID- 29464467 TI - Insight into the molecular mechanism of yeast acetyl-coenzyme A carboxylase mutants F510I, N485G, I69E, E477R, and K73R resistant to soraphen A. AB - Acetyl-coenzyme A carboxylases (ACCs) is the first committed enzyme of fatty acid synthesis pathway. The inhibition of ACC is thought to be beneficial not only for diseases related to metabolism, such as type-2 diabetes, but also for infectious disease like bacterial infection disease. Soraphen A, a potent allosteric inhibitor of BC domain of yeast ACC, exhibit lower binding affinities to several yeast ACC mutants and the corresponding drug resistance mechanisms are still unknown. We report here a theoretical study of binding of soraphen A to wild type and yeast ACC mutants (including F510I, N485G, I69E, E477R, and K73R) via molecular dynamic simulation and molecular mechanics/generalized Born surface area free energy calculations methods. The calculated binding free energies of soraphen A to yeast ACC mutants are weaker than to wild type, which is highly consistent with the experimental results. The mutant F510I weakens the binding affinity of soraphen A to yeast ACC mainly by decreasing the van der Waals contributions, while the weaker binding affinities of Soraphen A to other yeast ACC mutants including N485G, I69E, E477R, and K73R are largely attributed to the decreased net electrostatic (DeltaEele + DeltaGGB) interactions. Our simulation results could provide important insights for the development of more potent ACC inhibitors.

We successfully observed the microvascular structure of the inflamed portion between the abdominal wall and surface of the liver in an elderly patient with FHCS using a superb microvascular imaging (SMI) system, a new technology developed for observing minute vascular flow. An 80-year-old Japanese female with right dorsal to lateral abdominal pain and fever came to our hospital. Anti-chlamydia antibodies were positive. SMI revealed signals suggesting small vessels passing from the liver surface to the hypoechoic space. PMID- 29464469 TI - Ultrasonographic images of the hand in a case with early eosinophilic fasciitis. AB - Eosinophilic fasciitis (EF), a rare rheumatic disease, usually affects the limbs symmetrically and generally spares the hands and feet. Cases of unilateral hand involvement are rarely reported. Here, we report such a rare case. Ultrasonography demonstrated thickening of the overlying skin and subcutaneous tissue, peripheral deep fascia, myositis of lumbrical muscles and adductor pollicis muscle, and edema surrounding flexor digitorum tendons. It reminds us that EF should be considered in the differential diagnosis of unilateral painful hand swelling despite being uncommon. Ultrasonography can be used to aid the diagnosis and monitor therapeutic response in patients with EF. PMID- 29464470 TI - Open flap versus flapless placement of dental implants. A randomized controlled pilot trial. AB - The aim of this study was to compare the immediate postoperative period of participants rehabilitated with dental implants placed with a conventional technique or with a minimally invasive technique, without a mucoperiosteal flap elevation (flapless). Participants who needed implant placement were divided into two groups: one group was operated using a mucoperiosteal flap elevation (G_A), and the other with a flapless surgical technique (G_B). Objective clinical parameters including oral hygiene, mouth opening, inflammation (facial perimeter), surgical time and analgesic consumption, as well as subjective parameters of pain and degree of satisfaction with the procedure, were evaluated. 48 implants were placed in 30 participants (15 participants per group). Oral hygiene index, maximum interincisal opening, pain and analgesic consumption values had a significant difference between groups favoring the flapless technique at 24 h and 7 days but at the 15 days' follow-up the differences were only significant for oral hygiene and pain (P < 0.05); there were no statistically significant differences between groups in terms of facial perimeter values and surgical time (P > 0.05). Average on the degree of satisfaction was of 2.6 (SD 0.8) for G_A and 3.6 (SD 1.02) for G_B (P = 0.06). One implant placed in G_A (2.0%) failed before prosthetic loading due to mobility and pain at 3 months' follow-up. Participants operated for implant placement with flapless surgical technique go through less postoperative discomfort. Both techniques show high success rates, but to perform a flapless technique patients must be properly selected. PMID- 29464472 TI - "Lethal talk or healthful words?

AB - BACKGROUND: Sleep impairment is highly prevalent among resident physicians and is associated with both adverse patient outcomes and poor resident mental and physical health. Risk factors for sleep problems during residency are less clear, and no screening model exists to identify residents at risk for sleep impairment. OBJECTIVE: The objective of this study was to assess change in resident sleep during training and to evaluate utility of baseline sleep screening in predicting future sleep impairment. DESIGN: This is a prospective observational repeated measures survey study. PARTICIPANTS: The participants comprised PGY-1 residents across multiple specialties at Partners HealthCare hospitals. MAIN MEASURES: Main measures used for this study were demographic queries and two validated scales: the Pittsburgh Sleep Quality Index (PSQI), measuring sleep quality, and the Epworth Sleepiness Scale (ESS), measuring excessive daytime sleepiness. KEY RESULTS: Two hundred eighty-one PGY-1 residents completed surveys at residency orientation, and 153 (54%) completed matched surveys 9 months later. Mean nightly sleep time decreased from 7.6 to 6.5 hours (p < 0.001). Mean PSQI score increased from 3.6 to 5.2 (p < 0.001), and mean ESS score increased from 7.2 to 10.4 (p < 0.001). The proportion of residents exceeding the scales' clinical cutoffs increased over time from 15 to 40% on the PSQI (p < 0.001) and from 26 to 59% on the ESS (p < 0.001). Baseline normal sleep was not protective: 68% of residents with normal scores on both scales at baseline exceeded the clinical cutoff on at least one scale at follow-up. Greater age and fewer children increased follow-up PSQI score (p < 0.001) but not ESS score. CONCLUSIONS: During PGY-1 training, residents experience worsening sleep duration, quality of sleep, and daytime sleepiness. Residents with baseline impaired sleep tend to remain impaired. Moreover, many residents with baseline normal sleep experience sleep deterioration over time. Sleep screening at residency orientation may identify some, but not all, residents who will experience sleep impairment during training.

AB - AIM: To retrospectively investigate the prognostic role of the ratio between target lesion and liver SUVmax (rPET) in patients with follicular lymphoma (FL) submitted to FDG-PET/CT at the end of immuno-chemotherapy (PI-PET), and to compare rPET with International Harmonization Project criteria (IHP), Deauville Score (5p-DS) and FL International Prognostic Index at diagnosis (FLIPI). METHODS: Eighty-nine patients with FL undergoing PI-PET were evaluated. The receiver operating characteristic (ROC) approach was applied to identify the optimal cut-point of rPET with respect to 5-years progression free survival (PFS). The prognostic significance of rPET was compared with IHP, DS and FLIPI. Positive predictive value (PPV) and negative predictive value (NPV) were calculated using the presence of adverse events as gold standard. RESULTS: The ROC analysis for rPET as predictor of progression showed an optimal rPET cut point of 0.98. Patients with positive values of IHP, DS and rPET had a PFS of 50, 30 and 31%. PPV were of 56, 80 and 80%, NPV of 83, 86 and 88%, respectively. DS and rPET differed only in two patients. FLIPI was not predictive of progression and relapse. CONCLUSIONS: rPET is a prognostic factor in patients with FL submitted to PI-PET. Although it has a similar prognostic power as DS, it can have methodological advantages over visual analysis. PI-PET with different evaluation systems has a stronger prognostic power than FLIPI at diagnosis, so it could be useful to identify patients with FL at risk for early relapse after immuno-chemotherapy.

AB - This opportunistic case-study highlights striking differences in 6 urban children's and 12 preservice suburban middle-class teachers' perception of science and discuss consequences of science education and beyond. I found that all of the interviewed urban children demonstrated scientific inquiries and interests outside of the school science education that can be characterized by diverse simultaneous discourses from diverse practices, i.e., "heterodiscoursia" (Matusov in Culture & Psychology, 17(1), 99-119, 2011b), despite their diverse, positive and negative, attitudes toward school science. In contrast to the urban children's mixed attitudes to science, the preservice teachers view science negatively. They could not see science inquiries in the videotaped interviews of the urban children. There seemed to be many reasons for that. One of the possible reasons for that was that the preservice teachers tried to purify the science practice. Another reason was that they did not see a necessity to be interested and engaged in the curriculum that they are going to teach in future. The pedagogical consequences and remedies are discussed. PMID- 29464483 TI - Mutational subtypes of JAK2 and CALR correlate with different clinical features in Japanese patients with myeloproliferative neoplasms. AB - The majority of patients with Philadelphia chromosome-negative myeloproliferative neoplasms (MPNs) harbor JAK2, CALR, or MPL mutations. We compared clinical manifestations of different subtypes of JAK2 and CALR mutations in Japanese patients with MPNs. Within our cohort, we diagnosed 166 patients as polycythemia vera (PV), 212 patients as essential thrombocythemia (ET), 23 patients as pre primary myelofibrosis (PMF), 65 patients as overt PMF, and 27 patients as secondary myelofibrosis following the 2016 WHO criteria. Compared to patients with JAK2V617F-mutated PV, JAK2 exon 12-mutated PV patients were younger, showed lower white blood cell (WBC) counts, lower platelet counts, higher red blood cell counts, and higher frequency of thrombotic events. Compared to JAK2-mutated ET patients, CALR-mutated ET patients were younger, showed lower WBC counts, lower hemoglobin levels, higher platelet counts, and fewer thrombotic events. CALR type 1-like mutation was the dominant subtype in CALR-mutated overt PMF patients. Compared with JAK2V617F-mutated ET patients, JAK2V617F-mutated pre-PMF patients showed higher LDH levels, lower hemoglobin levels, higher JAK2V617F allele burden, and higher frequency of splenomegaly. In conclusion, Japanese patients with MPNs grouped by different mutation subtypes exhibit characteristics similar to those of their Western counterparts. In addition, ET and pre-PMF patients show different characteristics, even when restricted to JAK2V617F-mutated patients. PMID- 29464484 TI - Characteristics and outcome of chronic myeloid leukemia patients with E255K/V BCR ABL kinase domain mutations. AB - Kinase domain (KD) mutations of ABL1 represent the most common resistance mechanism to tyrosine kinase inhibitors (TKI) in CML. Besides T315I, mutations in codon 255 are highly resistant mutations in vitro to all TKI. We aimed to study the incidence, prognosis, and response to treatment in patients with E255K/V. We evaluated 976 patients by sequencing of BCR-ABL1 fusion transcript for ABL1 KD mutations. We identified KD mutations in 381 (39%) patients, including E255K/V in 48 (13% of all mutations). At mutation detection, 14 patients (29%) were in chronic phase (CP), 12 (25%) in accelerated phase (AP), and 22 (46%) in blast phase (BP). 9/14 CP patients responded to treatment (best response complete hematologic response-CHR-4; complete cytogenetic response-CCyR-1; major molecular response-MMR-4); only 4/12 AP patients (CHR 3; MMR 1) and 7/22 BP patients responded (CCyR 2; MMR 2; partial cytogenetic response-PCyR-3). After a median follow-up of 65 months from mutation detection, 36 patients (75%) died: 9/14 (64%) in CP, 9/12 (75%) in AP, and 18/22 (82%) in BP (p = 0.003); median overall survival was 12 months. Patients with E255K/V mutation have a poor prognosis, regardless of the stage of the disease at detection. PMID- 29464485 TI - Determining the Roles of a Conserved alpha-Helix in a Global Virulence Regulator from Staphylococcus aureus. AB - SarA, a pleiotropic transcription regulator, is encoded by Staphylococcus aureus, a pathogenic bacterium. The expression of many virulence and non-virulence genes in S. aureus is modulated by this regulator. Structural studies have shown it to be a winged-helix DNA-binding protein carrying two monomers. Each SarA monomer is composed of five alpha-helices (alpha1-alpha5), three beta-strands (beta1-beta3) and multiple loops. The putative DNA binding region of SarA is constituted with alpha3, alpha4, beta2, and beta3, whereas, its dimerization seems to occur using alpha1, alpha2, and alpha5. Interestingly, many SarA-like proteins are dimeric and use three or more helices for their dimerization. To clearly understand the roles of helix alpha1 in the dimerization, we have constructed and purified a SarA mutant (Deltaalpha1) that lacks helix alpha1. Our in-depth studies with Deltaalpha1 indicate that the helix alpha1 is critical for preserving the structure, DNA binding activity and thermodynamic stability of SarA. However, the helix has little affected its dimerization ability. Possible reasons for such anomaly have been discussed at length. PMID- 29464487 TI - Binocular visual function of myopic pseudophakic monovision. AB - PURPOSE: To compare binocular visual function of myopic pseudophakic patients with myopic monovision to patients without monovision. STUDY DESIGN: Randomized comparative study METHODS: Sixty patients were randomized to one of two groups: patients whose refraction was targeted to -2.75 diopters (D) in the dominant eye and -1.75D in the nondominant eye (myopic monovision group), and patients whose refraction was targeted to -2.75D bilaterally (non-monovision group). Binocular uncorrected and corrected visual acuity at various distances was measured using an all-distance vision tester, and contrast visual acuity and near stereoacuity were examined. RESULTS: In the myopic monovision group mean refraction was -2.74D in the dominant eyes and -1.94D in the nondominant eyes, and in the non monovision group it was -2.96D bilaterally. Mean binocular uncorrected distance (UDVA) and intermediate visual acuity (UIVA) from 0.5 m to 5.0 m were significantly better in the myopic monovision group than in the non-monovision group (P<= 0.0134), while binocular uncorrected near visual acuity (UNVA) at 0.3 m did not differ significantly between groups. The distribution of UIVA and UDVA was significantly better in the myopic monovision group (P<= 0.0035). Corrected visual acuity at any distance, photopic and mesopic contrast visual acuity, and stereoacuity did not differ significantly between groups. CONCLUSION: Patients with myopic monovision exhibited significantly better binocular UIVA and UDVA than those without monovision, while UNVA, corrected visual acuity, contrast sensitivity, and stereoacuity were comparable between groups, suggesting that this method is useful for patients who want to see near and intermediate distances without spectacles. PMID- 29464486 TI - MicroRNA-322 Cluster Promotes Tau Phosphorylation via Targeting Brain-Derived Neurotrophic Factor. AB - Brain-derived neurotrophic factor (BDNF) is a crucial regulator to support synaptic plasticity and neuronal survival, its significant decrease is a pathophysiological hallmark in Alzheimer's disease (AD) brains and accounts for poor prognosis. MicroRNAs (miRNAs) interfere with the translation of target mRNAs and control a variety of physiological and pathological processes. MiR-322 is the rodent homologue of human miR-424, it is involved in the modulation of cell differentiation, proliferation, apoptosis and metabolic activities in diverse tissues and organs. However, the roles and potential mechanisms of miR-322 remain elusive in AD pathogenesis. Here we observed miR-322 is significantly increased along with BDNF decrease in AD mouse brain. Bioinformatics prediction implicated that BDNF 3'-untranslated region (3'-UTR) possesses the putative target sequence of miR-322. Luciferase reporter assay identified that miR-322 can directly conjugate to BDNF 3'-UTR. The functional research showed that MiR-322 input deregulates BDNF expression at either mRNA or protein levels, whereas miR-322 silence restores BDNF expression in vitro. Furthermore, we found miR-322 promotes Tau phosphorylation via negatively controlling BDNF-TrkB receptor activation, otherwise MiR-322 silence restores TrkB activation and attenuates tau phosphorylation. Collectively, this study demonstrated a novel miRNA-dependent manner of BDNF degradation in AD pathogenesis, it may drive a miRNAs- or BDNF based therapeutic strategies against Alzheimer's disease. PMID- 29464488 TI - Reinforced scleral fixation of foldable intraocular lens by double sutures: comparison with intrascleral intraocular lens fixation. AB - PURPOSE: The purpose of this study is to describe a new technique for small incision scleral fixation of intraocular lens (IOL) using double 10-0 polypropylene sutures, and to report the outcomes of IOL position compared with intrascleral IOL fixation at 12-month follow-up. STUDY DESIGN: A retrospective comparative study. METHOD: This new technique, called double sutured scleral fixated-IOL (DSF-IOL), was created to help with long-term knots strengthening by applying double sutures to each IOL haptic using an augmented Clove-hitch knot instead of the conventional knots tied by single suture. The tilt and decenter of IOL were measured by Scheimpflug camera and other refractive outcomes were compared between two groups at 12-month follow-up. RESULTS: This study consisted of 26 eyes (54.2%) from the DSF-IOL group, and 22 eyes (45.8%) from the intrascleral fixated IOL (ISF-IOL) group. No significant differences of mean absolute degree of IOL tilt (2.90 +/- 0.77 vs 2.82 +/- 0.72; p = 0.633) and IOL decenter (151.90 +/- 59.80 vs 175.0 +/- 73.14 microns; p = 0.265) were found between the two groups. Post-operative LogMAR visual acuity was not statistically different between the two groups (0.32 +/- 0.17 vs 0.41 +/- 0.19, p = 0.089). Early post-operative hypotony was only present in the ISF-IOL group (13.6%). CONCLUSION: This study shows that DSF-IOL is as effective as ISF-IOL. This technique can be a simpler approach to optimize small-incision scleral fixation of IOL without the complications associated with intrascleral IOL fixation. PMID- 29464489 TI - Learning neural connectivity from firing activity: efficient algorithms with provable guarantees on topology. AB - The connectivity of a neuronal network has a major effect on its functionality and role. It is generally believed that the complex network structure of the brain provides a physiological basis for information processing. Therefore, identifying the network's topology has received a lot of attentions in neuroscience and has been the center of many research initiatives such as Human Connectome Project. Nevertheless, direct and invasive approaches that slice and observe the neural tissue have proven to be time consuming, complex and costly. As a result, the inverse methods that utilize firing activity of neurons in order to identify the (functional) connections have gained momentum recently, especially in light of rapid advances in recording technologies; It will soon be possible to simultaneously monitor the activities of tens of thousands of neurons in real time. While there are a number of excellent approaches that aim to identify the functional connections from firing activities, the scalability of the proposed techniques plays a major challenge in applying them on large-scale datasets of recorded firing activities. In exceptional cases where scalability has not been an issue, the theoretical performance guarantees are usually limited to a specific family of neurons or the type of firing activities. In this paper, we formulate the neural network reconstruction as an instance of a graph learning problem, where we observe the behavior of nodes/neurons (i.e., firing activities) and aim to find the links/connections. We develop a scalable learning mechanism and derive the conditions under which the estimated graph for a network of Leaky Integrate and Fire (LIf) neurons matches the true underlying synaptic connections. We then validate the performance of the algorithm using artificially generated data (for benchmarking) and real data recorded from multiple hippocampal areas in rats.

PMID- 29464491 TI - Do I Need to Operate on That in the Middle of the Night? Development of a Nomogram for the Diagnosis of Severe Acute Cholecystitis. AB - BACKGROUND: Some authors have proposed different predictive factors of severe acute cholecystitis, but generally, the results of risk analyses are expressed as odds ratios, which makes it difficult to apply in the clinical practice of the acute care surgeon. The severe form of acute cholecystitis should include both gangrenous and phlegmonous cholecystitis, due to their severe clinical course, and cholecystectomy should not be delayed. The aim of this study was to create a nomogram to obtain a graphical tool to compute the probability of having a severe acute cholecystitis. METHODS: This is a retrospective study on 393 patients who underwent emergency cholecystectomy between January 2010 and December 2015 at the Acute Care Surgery Service of the S. Anna University Hospital of Ferrara, Italy. Patients were classified as having a non-severe acute cholecystitis or a severe acute cholecystitis (i.e., gangrenous and phlegmonous) based on the final pathology report. The baseline characteristics, pre-operative signs, and abdominal ultrasound (US) findings were assessed with a stepwise multivariate logistic regression analysis to predict the risk of severe acute cholecystitis, and a nomogram was created. RESULTS: Age as a continuous variable, WBC count >= 12.4 * 103/MUl, CRP >=9.9 mg/dl, and presence of US thickening of the gallbladder wall were significantly associated with severe acute cholecystitis at final pathology report. A significant interaction between the effect of age and CRP was found. Four risk classes were identified based on the nomogram total points. CONCLUSIONS: Patients with a nomogram total point >= 74 should be considered at high risk of severe acute cholecystitis (at 74 total point, sensitivity = 78.5%; specificity = 78.2%; accuracy = 78.3%) and this finding could be useful for surgical planning once confirmed in a prospective study comparing the risk score stratification and clinical outcomes.

AB - Essential oil of eucalyptus species is among the most common traded essential oils in the world. There is an increasing interest in the application of eucalyptus oil as a natural additive in food and pharmaceutical industry. The present study was undertaken to identify the phytoconstituents present in the essential oil of Eucalyptus globulus leaves (EO) and ascertain their protective effect against ketamine-induced psychosis in rats. GC-MS technique was used for analysis of phytoconstituents present in EO. Ketamine (50 mg/kg, i.p.) was used to induce psychosis in rats. Photoactometer, forced swim test and pole climb avoidance test were used to evaluate the protective effects of the EO (500, 1000 and 2000 mg/kg, p.o.) on acute and chronic administration. Bar test was used to test the side effect of EO. Biochemical and neurochemical estimations were carried out to explore the possible mechanism of action. GC-MS analysis of EO showed the presence of a number of biologically active compounds. EO at the dose of 500, 1000 and 2000 mg/kg, p.o. on acute and chronic administration, decreased locomotor activity, immobility duration and latency to climb the pole. EO was effective to facilitate the release of GABA, increase GSH levels, inhibit dopamine neurotransmission and decrease TNF-alpha levels as well as diminish AChE activity in different regions of the brain. EO at the dose of 500, 1000 mg/kg did not produce cataleptic behavior in rats. EO at the dose of 500, 1000 mg/kg produced protective effects against ketamine-induced psychosis and can be further explored clinically against neuropsychiatric disorders. PMID- 29464496 TI - Tumor Targeting via Sialic Acid: [68Ga]DOTA-en-pba as a New Tool for Molecular Imaging of Cancer with PET. AB - PURPOSE: The aim of this study was to demonstrate the potential of Ga-68-labeled macrocycle (DOTA-en-pba) conjugated with phenylboronic vector for tumor recognition by positron emission tomography (PET), based on targeting of the overexpressed sialic acid (Sia). PROCEDURES: The imaging reporter DOTA-en-pba was synthesized and labeled with Ga-68 at high efficiency. Cell binding assay on Mel C and B16-F10 melanoma cells was used to evaluate melanin production and Sia overexpression to determine the best model for demonstrating the capability of [68Ga]DOTA-en-pba to recognize tumors. The in vivo PET imaging was done with B16 F10 tumor-bearing SCID mice injected with [68Ga]DOTA-en-pba intravenously. Tumor, blood, and urine metabolites were assessed to evaluate the presence of a targeting agent. RESULTS: The affinity of [68Ga]DOTA-en-pba to Sia was demonstrated on B16-F10 melanoma cells, after the production of melanin as well as Sia overexpression was proved to be up to four times higher in this cell line compared to that in Mel-C cells. Biodistribution studies in B16-F10 tumor-bearing SCID mice showed blood clearance at the time points studied, while uptake in the tumor peaked at 60 min post-injection (6.36 +/- 2.41 % ID/g). The acquired PET images were in accordance with the ex vivo biodistribution results. Metabolite assessment on tumor, blood, and urine samples showed that [68Ga]DOTA-en-pba remains unmetabolized up to at least 60 min post-injection. CONCLUSIONS: Our work is the first attempt for in vivo imaging of cancer by targeting overexpression of sialic acid on cancer cells with a radiotracer in PET.

PMID- 29464498 TI - Milk Proteins Are Predigested Within the Human Mammary Gland. AB - Previous work demonstrates that proteases present in human milk release hundreds of peptides derived from milk proteins. However, the question of whether human milk protein digestion begins within the mammary gland remains incompletely answered. The primary objective of this study was to determine whether proteolytic degradation of human milk proteins into peptides begins within the mammary gland. The secondary objectives were to determine which milk proteases participate in the proteolysis and to predict which released peptides have bioactivity. Lactating mothers (n = 4) expressed their milk directly into a mixture of antiproteases on ice followed by immediate freezing of the milk to limit post-expression protease activity. Samples were analyzed for their peptide profiles via mass spectrometry and database searching. Peptidomics-based protease prediction and bioactivity prediction were each performed with several different approaches. The findings demonstrate that human milk contains more than 1,100 unique peptides derived from milk protein hydrolysis within the mammary gland. These peptides derived from 42 milk proteins and included 306 potential bioactive peptides. Based on the peptidomics data, plasmin was predicted to be the milk protease most active in the hydrolysis of human milk proteins within the mammary gland. Milk proteases actively cleave milk proteins within the mammary gland, initiating the release of functional peptides. Thus, the directly breastfed infant receives partially pre-digested proteins and numerous bioactive peptides. PMID- 29464499 TI - Catechin Attenuates Coronary Heart Disease in a Rat Model by Inhibiting Inflammation. AB - Accumulating evidence has established that systemic inflammation is an important pathophysiologic factor of coronary heart disease (CHD). In this study, we investigated whether catechin exerts anti-inflammatory function in CHD rats. CHD model of rats was established by high-fat diet feeding and pituitrin injection. The successful building of CHD model was confirmed using blood liquid biochemical analyzer. Additionally, the effects of catechin on CHD parameters and several inflammatory signaling were investigated. The levels of total cholesterol, high density lipoprotein, low-density lipoprotein cholesterin, triglyceride and blood glucose were all significantly elevated in CHD rats compared to them in control rats, suggesting the successful establishment of CHD model. Administration of catechin attenuated CHD by reversing the levels of creatine kinase, creatine kinase-MB, lactate dehydrogenase, cardiac troponin (cTnT), ventricular ejection fraction (LVEF) and systolic internal diameter (LVIDs). Additionally, several inflammatory biomarkers or cytokines such as C-reactive protein, lipoprotein associated phospholipase A2 (Lp-PLA2), interleukin (IL)-6 and tumor necrosis factor-alpha (TNF-alpha) were inhibited by catechin. In contrast to nuclear factor-kappa beta (NF-kappaB), several proteins involved in inflammation such as farnesoid X receptor, signal transducers and activators of transcription (STAT)-3 and protein kinase B (PKB/Akt) were all activated by catechin. Catechin could be used as a promising treatment for CHD based on its role in suppressing inflammation and balancing STAT-3 signaling.

AB - The neutral outcome of the recently reported school-based trial of probiotic K12 (The effect of the oral probiotic Streptococcus salivarius K12 on group A streptococcus pharyngitis: a pragmatic trial in schools) can be attributed at least partially to several readily identifiable confounding factors. Mainly, the execution and outcome were negatively impacted by (a) the suboptimal efficacy and frequency of K12 administration, (b) the failure both clinically and microbiologically to adequately diagnose and distinguish active group A streptococci (GAS) pharyngitis from harmless GAS carriage, and ( c ) the exceptionally low occurrence of GAS in this population at the time of the probiotic intervention due to recent high-intensity antibiotic exposure. PMID- 29464501 TI - A Systematic Review of Probiotic Interventions for Gastrointestinal Symptoms and Irritable Bowel Syndrome in Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME). AB - Gastrointestinal (GI) symptoms and irritable bowel (IB) symptoms have been associated with chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME). The aim of this study was to conduct a systematic review of these symptoms in CFS/ME, along with any evidence for probiotics as treatment. Pubmed, Scopus, Medline (EBSCOHost) and EMBASE databases were searched to source relevant studies for CFS/ME. The review included any studies examining GI symptoms, irritable bowel syndrome (IBS) and/or probiotic use. Studies were required to report criteria for CFS/ME and study design, intervention and outcome measures. Quality assessment was also completed to summarise the level of evidence available. A total of 3381 publications were returned using our search terms. Twenty-five studies were included in the review. Randomised control trials were the predominant study type (n = 24). Most of the studies identified examined the effect of probiotic supplementation on the improvement of IB symptoms in IBS patients, or IB symptoms in CFS/ME patients, as well as some other significant secondary outcomes (e.g. quality of life, other gastrointestinal symptoms, psychological symptoms). The level of evidence identified for the use of probiotics in IBS was excellent in quality; however, the evidence available for the use of probiotic interventions in CFS/ME was poor and limited. There is currently insufficient evidence for the use of probiotics in CFS/ME patients, despite probiotic interventions being useful in IBS. The studies pertaining to probiotic interventions in CFS/ME patients were limited and of poor quality overall. Standardisation of protocols and methodology in these studies is required.

PMID- 29464502 TI - Type 2 Diabetes Mellitus and Alzheimer's Disease: Overlapping Biologic Mechanisms and Environmental Risk Factors. AB - PURPOSE OF REVIEW: A number of studies over the past two decades have suggested that type 2 diabetes mellitus (T2DM) patients are at an increased risk of Alzheimer's disease (AD). Several common molecular pathways to cellular and metabolic dysfunction have been implicated in the etiology of both diseases. Here, we review the emerging evidence from observational studies that investigate the relationship between T2DM and AD, and of shared environmental risk factors, specifically air pollution and pesticides, associated with both chronic disorders. RECENT FINDINGS: Particulate matter and traffic-related air pollution have been widely associated with T2DM, and multiple studies have associated exposures with AD or cognitive function. Organochlorine (OC) and organophosphate (OP) pesticides have been associated with T2DM in multiple independent populations. Two populations have observed increased risks for OC and OP exposures and AD. Other studies, limited in exposure assessment, have reported increased risk of AD with any pesticide exposure assessments. This may suggest shared pathogenic pathways between environmental risk factors, T2DM, and AD. Research focusing on exposures related to both T2DM and AD could provide new disease insights on shared mechanisms and help shape innovative preventative measures and policy decisions. PMID- 29464504 TI - Significant and safe reduction of propofol sedation dose for geriatric population undergoing pacemaker implantation: randomized clinical trial. AB - OBJECTIVE: A previous multidisciplinary pilot study based on computer simulations for the geriatric population showed that a dose of 0.5 mg/kg/h of propofol could sedate patients older than 65 for pacemaker implantation. The present study validates that the pacemaker implantation can be done in the elderly using 0.5-1 mg/kg/h of propofol with hemodynamic stability. METHODS: 66 patients from 65 to 88 years old scheduled for pacemaker implantation were randomly assigned one of three doses of propofol. The first group received 2 mg/kg/h of propofol (P2) that is within normal range of the sedation dose. The second group received 1 mg/kg/h (P1) dose and the third group received the dose of 0.5 mg/kg/h (P0.5) according to the simulation-predicted dose for geriatric populations. RESULTS: All patients kept MAP between 76 and 85 mmHg, with no hypotension episodes in any of the groups; therefore, they were all hemodynamically stable during the procedure. BIS was between 80 and 65 during the pacemaker implantation for the three groups, BIS of group P2 was significantly lower than the other groups. BIS in groups P1 and P0.5 was within the appropriated range for moderate sedation. Brice was positive for auditory recalls only when there was arousing noise in the operating room. CONCLUSIONS: Moderate sedation, adequate for pacemaker implantation, can be achieved infusing 0.5-1 mg/kg/h of propofol in elderly patients when the patient has proper analgesia management at the device implantation site. The second important condition is to avoid unnecessary and alerting auditory and mechanical stimuli in the operating room, so that the patient will remain calm.

PMID- 29464506 TI - Idiopathic portal hypertension and extrahepatic portal venous obstruction. AB - BACKGROUND: Idiopathic portal hypertension (IPH) and extrahepatic portal venous obstruction (EHPVO) are non-cirrhotic vascular causes of portal hypertension (PHT). Variceal bleed and splenomegaly are the commonest presentations. AIM: The present review is intended to provide the existing literature on etiopathogenesis, clinical profile, diagnosis, natural history and management of IPH and EHPVO. RESULTS: IPH and EHPVO are both characterized by normal hepatic venous pressure gradient, moderate to massive splenomegaly with preserved liver synthetic functions. While the level of block in IPH is presinusoidal, in EHPVO it is at prehepatic level. Infections, autoimmunity, drugs, immunodeficiency and prothrombotic states are possible etiological agents in IPH. Contrastingly in EHPVO, prothrombotic disorders and local factors around the portal vein are the incriminating factors. Diagnosis is often clinical, supported by simple radiological tools. Natural history is defined by episodes of variceal bleed and symptoms related to enlarged spleen. Growth failure, portal biliopathy and minimal hepatic encephalopathy are additional concerns in EHPVO. Long-term survival is reasonably good with endoscopic surveillance; however, parenchymal extinction leading to decompensation is seen in a minority of patients in both the disorders. Surgical shunts revert the complications secondary to PHT. Meso Rex shunt has become the standard surgery in children with EHPVO. CONCLUSION: This review gives a detailed summary of these two vascular conditions of liver IPH and EHPVO. Further research is needed to understand the pathogenesis and natural history of these disorders. PMID- 29464509 TI - Agarotetrol: a source compound for low molecular weight aromatic compounds from agarwood heating. AB - Agarwood is known to generate a distinct fragrance upon heating and is used as both a medicine and a fragrant wood. Low molecular weight aromatic compounds (LACs) such as benzylacetone are emitted from agarwood on heating and have a sedative effect on mice. These are detected exclusively in the headspace vapor of heated agarwood and are absent in the wood itself; hence, some compounds in agarwood are thought to be converted to LACs by the process of heating. In this study, different fractions obtained from agarwood were analyzed to reveal the source compounds of LACs. Some LACs detected in the resinous agarwood were absent from the non-resinous parts and confirmed as characteristic of the resinous parts. The essential oil and hydrosol of agarwood obtained by distillation were analyzed by gas chromatography-mass spectrometry (GC-MS). Sesquiterpenes were detected in the essential oil, and sesquiterpenes and a variety of LACs were detected in the hydrosol. A hot water extract of agarwood remaining in the distillation flask after distillation was analyzed by high-performance liquid chromatography (HPLC), and agarotetrol was found to be the main compound. Purified agarotetrol was heated in a glass vial and its headspace vapor was analyzed by solid-phase microextraction GC-MS. Benzylacetone and other LACs were detected. These results indicate that agarotetrol, a chromone derivative, contributes to the fragrance of agarwood through the generation of LACs upon heating.

AB - Mesenchymal stem cells (MSCs) are an important population of multipotent stem cells that differentiate into multiple lineages and display great potential in bone regeneration and repair. Although the role of protein-coding genes in the osteogenic differentiation of MSCs has been extensively studied, the functions of noncoding RNAs in the osteogenic differentiation of MSCs are unclear. The recent application of next-generation sequencing to MSC transcriptomes has revealed that long noncoding RNAs (lncRNAs) are associated with the osteogenic differentiation of MSCs. LncRNAs are a class of non-coding transcripts of more than 200 nucleotides in length. Noncoding RNAs are thought to play a key role in osteoblast differentiation through various regulatory mechanisms including chromatin modification, transcription factor binding, competent endogenous mechanism, and other post-transcriptional mechanisms. Here, we review the roles of lncRNAs in the osteogenic differentiation of bone marrow- and adipose-derived stem cells and provide a theoretical foundation for future research.

AB - The root of Angelica acutiloba Kitagawa is an important crude drug in Kampo medicines (traditional Japanese medicine). Chemical evaluation of crude drugs is crucial to ensuring the safety and efficacy of herbal medicine; however, there is currently no chemical standard for the A. acutiloba crude drug in Japanese pharmacopoeia. (E)-ferulic acid (FA) is an important active ingredient of Angelica spp., including A. sinensis (Oliv.) Diels, and has been suggested as a marker for quality evaluation of those crude drugs. However, it has been controversial whether FA is a reliable marker constituent of A. acutiloba. To achieve effective extraction of FA from A. acutiloba, we compared three different extraction methods: alkaline hydrolysis, ethanol extraction, and hexane extraction. FA levels in these extracts were assessed using high performance liquid chromatography (HPLC), and alkaline hydrolysis was found to be the most effective. Furthermore, in the hydrolysate, FA was distinctly identified by thin layer chromatography (TLC) analysis. These results provide useful information for the quality control of the A. acutiloba crude drug. PMID- 29464511 TI - Computational Investigation of a Self-Powered Fontan Circulation. AB - Children born with anatomic or functional "single ventricle" must progress through two or more major operations to sustain life. This management sequence culminates in the total cavopulmonary connection, or "Fontan" operation. A consequence of the "Fontan circulation", however, is elevated central venous pressure and inadequate ventricular preload, which contribute to continued morbidity. We propose a solution to these problems by increasing pulmonary blood flow using an "injection jet" (IJS) in which the source of blood flow and energy is the ventricle itself. The IJS has the unique property of lowering venous pressure while enhancing pulmonary blood flow and ventricular preload. We report preliminary results of an analysis of this circulation using a tightly-coupled, multi-scale computational fluid dynamics model. Our calculations show that, constraining the excess volume load to the ventricle at 50% (pulmonary to systemic flow ratio of 1.5), an optimally configured IJS can lower venous pressure by 3 mmHg while increasing systemic oxygen delivery. Even this small decrease in venous pressure may have substantial clinical impact on the Fontan patient. These findings support the potential for a straightforward surgical modification to decrease venous pressure, and perhaps improve clinical outcome in selected patients. PMID- 29464512 TI - Feasibility of continuous sedation monitoring in critically ill intensive care unit patients using the NeuroSENSE WAVCNS index. AB - Sedation in the intensive care unit (ICU) is challenging, as both over- and under sedation are detrimental. Current methods of assessment, such as the Richmond Agitation Sedation Scale (RASS), are measured intermittently and rely on patients' behavioral response to stimulation, which may interrupt sleep/rest. A non-stimulating method for continuous sedation monitoring may be beneficial and allow more frequent assessment. Processed electroencephalography (EEG) monitors have not been routinely adopted in the ICU. The aim of this observational study was to assess the feasibility of using the NeuroSENSETM monitor for EEG-based continuous sedation assessment. With ethical approval, ICU patients on continuous propofol sedation were recruited. Depth-of-hypnosis index (WAVCNS) values were obtained from the NeuroSENSE. Bedside nurses, blinded to the NeuroSENSE, performed regular RASS assessments and maintained the sedation regimen as per standard of care. Participants were monitored throughout the duration of their propofol infusion, up to 24 h. Fifteen patients, with median [interquartile range] age of 57 [52-62.5] years were each monitored for a duration of 9.0 [5.7 20.1] h. Valid WAVCNS values were obtained for 89% [66-99] of monitoring time and were widely distributed within and between individuals, with 6% [1-31] spent < 40 (very deep), and 3% [1-15] spent > 90 (awake). Significant EEG suppression was detected in 3/15 (20%) participants. Observed RASS matched RASS goals in 36/89 (40%) assessments. The WAVCNS variability, and incidence of EEG suppression, highlight the limitations of using RASS as a standalone sedation measure, and suggests potential benefit of adjunct continuous brain monitoring. PMID- 29464513 TI - Lipids in RA: Is Less Not Necessarily More? AB - PURPOSE OF REVIEW: In rheumatoid arthritis (RA), lipid levels are dynamic and can fluctuate along with changes in inflammation. A reduction in inflammation, most commonly as a result of disease-modifying anti-rheumatic drug (DMARD) therapy, is associated with increases in total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C). In this review, we discuss new evidence shedding light on the potential mechanism underlying changes in lipid levels observed with changes in inflammation. RECENT FINDINGS: Measured lipid levels in the blood are a result of a balance between synthesis and catabolism or absorption. Recent human studies in active RA show that the catabolic rates of lipids are higher than expected compared to expected rates in the general population. DMARD therapy appears to allow a return to baseline lower catabolic rates, resulting in an apparent increase in lipids. Increases in lipids observed with control of inflammation and RA treatment suggest a return to homeostasis. Studies are underway to understand the overall impact on cardiovascular risk in RA when lipid levels increase as a result of controlling inflammation.

AB - BACKGROUND: Eligibility of nipple-sparing mastectomy has been expanded. The purpose of this study was to evaluate interobserver agreement regarding magnetic resonance imaging (MRI) descriptors important in determining eligibility for mastectomy, and to investigate the significance of enhancement extending to the areola concerning nipple-areolar complex (NAC) involvement. METHODS: Fifty-one cases with histologically confirmed NAC involvement and 54 cases with negative NAC were enrolled. Two radiologists assessed the following factors: lesion morphology (mass or non-mass enhancement); intra-nipple bright signal; enhancement extending to the areola; abnormal nipple enhancement; and tumor nipple distance. Factors that showed a significant association with outcome in the univariate analysis were assessed by means of multivariate analysis using a logistic regression model. Interobserver agreement between observers was assessed by calculating kappa values (dichotomous variables), or intraclass correlation coefficients (ICCs; continuous variables). RESULTS: In multivariate analysis of the results from the two observers, tumor-nipple distance (observer 1: odds ratio [OR] 0.93; 95% confidence interval [CI] 0.88-0.99; observer 2: OR 0.89; 95% CI 0.83-0.95) and enhancement extending to the areola (observer 1: OR 17.9; 95% CI 1.97-162.2; observer 2: OR 24.0; 95% CI 2.62-219.7) were found to be significant predictors of NAC involvement. A substantial agreement (kappa = 0.64-0.71) for every dichotomous variable and an almost perfect agreement (ICC = 0.86) for continuous variable were observed. CONCLUSIONS: Findings of breast MRI for NAC preservation had good interobserver agreement. Enhancement extending to the areola, together with tumor-nipple distance, was significant factors for NAC involvement. PMID- 29464517 TI - Evaluation of Kefir as a New Anodic Biocatalyst Consortium for Microbial Fuel Cell. AB - Kefir, a combined consortium of bacteria and yeast encapsulated by a polymeric matrix of exopolysaccharides, was used as anodic biocatalyst in a two-chamber microbial fuel cell (MFC). Fermentation was followed during 72 h and polarization curves were obtained from linear sweep voltammetry. The effect of methylene blue as charge-transfer mediator in the kefir metabolism was evaluated. UV/Vis spectrophotometry and cyclic voltammetry were applied to evaluate the redox state of the mediator and to characterize the electrochemical activity, whereas current interruption was used for internal resistance determination. Aiming to establish a relationship between the microbial development inside the anodic chamber with the generated power in the MFC, total titratable acidity, pH, viscosity, carbohydrate assimilation, and microbial counting were assayed. The kefir-based MFC demonstrated a maximum power density of 54 mW m-2 after 24 h fermentation, revealing the potential use of kefir as a biocatalyst for microbial fuel cells. PMID- 29464518 TI - ERP Source Analysis Guided by fMRI During Familiar Face Processing. AB - Event related potentials (ERPs) provide precise temporal information about cognitive processing, but with poor spatial resolution, while functional magnetic resonance imaging (fMRI) reliably identifies brain areas involved, but with poor temporal resolution. Here we use fMRI to guide source localization of the ERPs at different times for studying the temporal dynamics of the neural system for recognizing familiar faces. fMRI activation areas were defined in a previous experiment applying the same paradigm used for ERPs. The Bayesian model averaging (BMA) method was used to estimate the generators of the ERPs to unfamiliar, visually familiar, and personally-familiar faces constraining the model by fMRI activation results. For this, higher prior probabilities in the solution space were assigned to the fMRI-defined regions, which included face-selective areas and other areas related to "person knowledge" retrieval. Source analysis was carried out in three-time windows: early (150-210 ms), middle (300-380 ms) and late (460-580 ms). The early and middle responses were generated in fMRI-defined areas for all face categories, while these areas do not contribute to the late response. Different areas contributed to the generation of the early and middle ERPs elicited by unfamiliar faces: fusiform (Fus), inferior occipital, superior temporal sulcus and the posterior cingulate (PC) cortices. For familiar faces, the contributing areas were Fus, PC and anterior temporal areas for visually familiar faces, with the addition of the medial orbitofrontal areas and other frontal structures for personally-significant faces. For both unfamiliar and familiar faces, more extended and reliable involvement of contributing areas were obtained for the middle compare with early time window. Our fMRI guide ERP source analysis suggested the recruitment of person-knowledge processing areas as early as 150-210 ms after stimulus onset during recognition of personally-familiar faces. We concluded that fMRI-constrained BMA source analysis provide information regarding the temporal-dynamics in the neural system for cognitive processsing. PMID- 29464516 TI - Quantitative Comparison of Primary Cilia Marker Expression and Length in the Mouse Brain. AB - Primary cilia are small, special cellular organelles that provide important sensory and signaling functions during the development of mammalian organs and coordination of postnatal cellular processes. Dysfunction of primary cilia are thought to be the main cause of ciliopathies, a group of genetic disorders characterized by overlapping developmental defects and prominent neurodevelopmental features. Although, disrupted cilia-linked signaling pathways have been implicated in the regulation of numerous neuronal functions, the precise role of primary cilia in the brain are still unknown. Importantly, studies of recent years have highlighted that different functions of primary cilia are reflected by their diverse morphology and unique signaling components localized in the ciliary membrane. In the present study, we conducted a comparative analysis of the expression pattern, distribution and length of adenylyl cyclase 3, somatostatin receptor 3, and ADP-ribosylation factor-like protein 13B expressing primary cilia in the mouse brain. We show that cilia of neurons and astrocytes display a well characterized distribution and ciliary marker arrangements. Moreover, quantitative comparison of their length, density and occurrence rate revealed that primary cilia exhibit region-specific alternations. In summary, our study provides a comprehensive overview of the cellular organization and morphological traits of primary cilia in regions of the physiological adult mouse brain. PMID- 29464520 TI - Infrared Spectroscopy and Imaging in Stem Cells and Aging Research. AB - The effect of aging process on stem cell function is crucial because of their critical role in tissue regeneration and repair. The impact of aging on stem cells needs to be understood clearly for the success of clinical application and obtaining desired therapeutic outcome throughout the novel stem cell based therapies. The existing methods used to monitor and characterize the stem cells have some unwanted effects on the properties of stem cells and these methods also do not provide real-time information about cellular conditions. These challenges enforce the usage of nondestructive, rapid, sensitive, high-quality, label-free, cheep, and innovative chemical monitoring methods. In this context, vibrational spectroscopy provides promising alternative to get new information into the field of stem cell biology for chemical analysis, quantification, and imaging of stem cells. Infrared spectroscopy and imaging coupled with chemometric methods can be used as novel and complimentary methods to obtain new insight into stem cell studies for future therapeutic and regenerative medicine. PMID- 29464519 TI - MRI Verification of a 10-20 Targeting Protocol Used During Transcranial Magnetic Stimulation Sessions for Tinnitus. AB - Langguth et al. (2006) described a method for targeting primary auditory cortex (PAC) during transcranial magnetic stimulation (TMS) using the 10-20 electroencephalography system. Study aims were to measure the degree of accuracy in placing the TMS coil on the scalp overlying PAC using the 10-20 method and determine the extent to which accuracy depends on the hemisphere of the coil placement. Twelve participants underwent anatomical magnetic resonance imaging (MRI) of their head in a 3T scanner. Before imaging, a fiducial marker was placed on their scalp corresponding to the TMS coil position. MRI scans were analyzed to determine the distance from the fiducial marker to PAC for each participant. On average, the 10-20 method resulted in distances in the medial-lateral, anterior posterior, and inferior-superior dimensions that were within a few millimeters (~ 4 mm) of each other between the left and right hemispheres. The fiducial marker was, on average, 10.4 mm superior and 10.8 mm posterior to the optimal scalp location that minimized the distance to PAC. Individual asymmetries and other systematic differences found in this study raise important considerations to keep in mind that might necessitate using an MRI-guided method of coil-positioning when targeting PAC for TMS. PMID- 29464521 TI - Remembering the place with the tiger: Survival processing can enhance source memory. AB - Rating the relevance of words for survival in the grasslands of a foreign land often leads to a memory advantage. However, it is as yet unclear whether the survival processing effect generalizes to source memory. Here, we examined whether people have enhanced source memory for the survival context in which an item has been encountered. Participants were asked to make survival-based or moving-based decisions about items prior to a classical source memory test. A multinomial model was used to measure old-new discrimination, source memory, and guessing biases separately. We replicated the finding of a survival advantage in old-new recognition. Extending previous results, we also found a survival processing advantage in source memory. These results are in line with the richness-of-encoding explanation of the survival processing advantage and with an adaptive perspective on memory. PMID- 29464522 TI - Protective effects of a modified apelin-12 and dinitrosyl iron complexes in experimental cardioplegic ischemia and reperfusion. AB - The maintenance of nitric oxide (NO) bioavailability has been recognized as an important component of myocardial protection during cardiac surgery. This study was designed to evaluate the efficacy of using two NO-donating compounds in cardioplegia and reperfusion: (i) a modified peptide apelin-12 (MA12) that activates endothelial NO synthase (eNOS) and (ii) dinitrosyl iron complexes with reduced glutathione (DNIC-GS), a natural NO vehicle. Isolated perfused working rat hearts were subjected to normothermic global ischemia and reperfusion. St. Thomas' Hospital cardioplegic solution (STH) containing 140 MUM MA12 or 100 MUM DNIC-GS was used. In separate series, 140 MUM MA12 or 100 MUM DNIC-GS was administered at early reperfusion. Metabolic state of the hearts was evaluated by myocardial content of high-energy phosphates and lactate. Lactate dehydrogenase (LDH) activity in myocardial effluent was used as an index of cell membrane damage. Cardioplegia with MA12 or DNIC-GS improved recovery of coronary flow and cardiac function, and reduced LDH leakage in perfusate compared with STH without additives. Cardioplegic arrest with MA12 significantly enhanced preservation of high-energy phosphates and decreased accumulation of lactate in reperfused hearts. The overall protective effect of cardioplegia with MA12 was significantly greater than with DNIC-GS. The administration of MA12 or DNIC-GS at early reperfusion also increased metabolic and functional recovery of reperfused hearts. In this case, recovery of cardiac contractile and pump function indices was significantly higher if reperfusion was performed with DNIC-GS. The results show that MA12 and DNIC-GS are promising adjunct agents for protection of the heart during cardioplegic arrest and reperfusion. PMID- 29464523 TI - Methotrexate preferentially affects Tc1 and Tc17 subset of CD8 T lymphocytes. AB - Rheumatoid arthritis is considered a T-lymphocyte-mediated disease. However, studies have focussed on CD4 T-lymphocytes, ignoring CD8 T-lymphocytes despite the latter being found abundantly in the synovium. Specifically, there is little data of the effect of methotrexate, the gold-standard DMARD, on various CD8 cytokine T-lymphocyte subsets and conflicting data on CD4 subsets. In this prospective study, patients with active rheumatoid arthritis, who were 18 to 65 years of age, were treated with methotrexate (up to 25 mg per week) for 24 weeks. At baseline and 24 weeks, frequencies of CD8+IFNgamma+, CD8+IL17+, CD8+IL4+, corresponding CD4 subsets and plasma levels of IFNgamma, IL-12, IL-10, IL-4 and IL-17 were determined by flow cytometry. These are summarised as median (IQR = interquartile range, 25th-75th percentile) and paired data compared using Wilcoxon signed rank test. This study included 67 patients (F/M = 4:1) with rheumatoid arthritis, 57 (85%) being RF positive and 20 receiving prednisolone at baseline. Mean (+/- SD) dose of methotrexate at 24 weeks was 22.9 +/- 3.0 mg per week. On treatment with methotrexate, there was a significant (p = 0.04) decline in CD8+IFNgamma+ cells from 37.2 (IQR 19.4-60.2) to 22.7% (IQR 8.5-49.7) and a marginal increase in CD8+IL17+ cells from 0.3 (IQR 0.1-0.6) to 0.4 (IQR 0.2-1.2), p = 0.006. There was no significant change in the other subsets. There was also a significant decline in circulating levels of IL-12, IL-10 and IL-17 and marginal increase in IL-4. On evaluating by response, non-responders but not responders had a significant increase in CD8+IL17+ (p = 0.01). There is a significant decline of CD8+IFNgamma+ T cells and marginal increase in CD8+IL17+ T cells after methotrexate. Change in Tc1 subset may be mediated through reduction in IL-12 levels. PMID- 29464524 TI - Physical articular examination in the activity of rheumatoid arthritis: a systematic review of the literature : Systematic review of the literature regarding physical examination in rheumatoid arthritis. AB - To summarize evidence concerning the articular examination needed to determine rheumatoid arthritis (RA) activity (follow-up or control) via a systematic review. A search of Medline, Embase, Lilacs, SciELO, the Web of Science, the National Technical Reports Library, and the reference lists of relevant studies through March 2017 was conducted using a systematic methodology to identify studies of patients with RA older than 18 years in which a detailed description of the physical examination or a description of the components of the articular examination was provided. Of 8322 references, 74 studies were included according to the selection criteria, and 6 references were ultimately included at the end of the review. Most of the included studies (n = 5) were associated with a moderate risk of bias. There was great variability among the studies and the articular examination methods used. Some studies presented the examination with a complete specification of the technique (n = 2), the consensus of rheumatologists (n = 2), or training through audiovisual materials and face-to-face courses (n = 2), but none of the studies explicitly showed the technique by which the physical examination was performed. Despite the importance of the clinical evaluation and physical examination of patients with RA for diagnosis, prognosis, clinimetrics, and follow-up, evidence concerning how to perform the articular examination is scarce.

PMID- 29464526 TI - Characteristics of children with acute lymphoblastic leukemia presenting with arthropathy. AB - Acute lymphoblastic leukemia (ALL) is the most common childhood neoplasia and may present with arthralgia and arthritis, with the risk of misdiagnosis and diagnostic delay. We describe in detail arthropathy (arthritis/arthralgia) among children with leukemia as the children's laboratory results, misdiagnosis, and treatment before the diagnosis of ALL and the diagnostic delay. In this retrospective cohort study, we reviewed records of 286 children aged 1-15 years diagnosed with ALL from January 1992 to March 2013. We identified 26 children with arthralgia and 27 children with arthritis. The majority of the children had one or two joints involved (arthralgia 72%, arthritis 42%), and most often hips and knees. Morning stiffness was not reported. Imaging of affected joints was included in the initial workup of 77% of children with ALL and arthropathy, and 66% was abnormal. Misdiagnosis as JIA occurred in 26% and 71% of these children received treatment with intraarticular corticosteroids. The diagnostic delay was 3 weeks longer for the children with arthritis than those with arthralgia (median 54 vs 36 days), primarily as a consequence of a longer first doctor's delay. Compared to the children with arthralgia, the children with arthritis were more often misdiagnosed and treated with intraarticular steroid before the diagnosis of ALL. They also had longer diagnostic delay, primarily as a consequence of a longer first doctor's delay. PMID- 29464528 TI - The shaded side of the UHC cube: a systematic review of human resources for health management and administration in social health protection schemes. AB - Managers and administrators in charge of social protection and health financing, service purchasing and provision play a crucial role in harnessing the potential advantage of prudent organization, management and purchasing of health services, thereby supporting the attainment of Universal Health Coverage. However, very little is known about the needed quantity and quality of such staff, in particular when it comes to those institutions managing mandatory health insurance schemes and purchasing services. As many health care systems in low- and middle-income countries move towards independent institutions (both purchasers and providers) there is a clear need to have good data on staff and administrative cost in different social health protection schemes as a basis for investing in the development of a cadre of health managers and administrators for such schemes. We report on a systematic literature review of human resources in health management and administration in social protection schemes and suggest some aspects in moving research, practical applications and the policy debate forward. PMID- 29464529 TI - Prognostic Factors and the Role of Adjuvant Treatment in Periampullary Carcinoma: a Single-Centre Experience of 95 Patients. AB - PURPOSE: The effect of adjuvant treatment on those undergoing pancreaticoduodenectomy (PD) for periampullary carcinomas (PAC) is not well studied. Most studies employed chemoradiation as the adjuvant modality. We aimed to analyse clinicopathological differences between types of PACs, the prognostic factors and the role of adjuvant therapy (chemotherapy in the majority). METHODS: Patients with PAC who underwent PD from Jan 2011 to Dec 2015 were retrospectively analysed. RESULTS: Ninety-five patients with PAC underwent PD in the study period. Ampullary carcinoma (AC) was the most common. Pancreatic carcinomas (PC) were larger. AC had lower T stage, perineural invasion (PNI) and R1 resections. Median overall survival (OS) was 32.7 months. On multivariate analysis, lymph node ratio (LNR) >= 0.2 and advanced T stage adversely affected the OS. Fifty seven (66.3%) patients received adjuvant treatment, of which 50 had chemotherapy alone. Adjuvant treatment resulted in better OS in patients with T stage >= 3, lymph node involvement, LNR >= 0.2, lymphovascular invasion, PNI, tumour size > 2 cm, higher grade and distal cholangiocarcinoma. CONCLUSION: In patients of PAC undergoing PD, AC had favourable clinicopathological profile. LNR >= 0.2 and advanced T stage adversely affected OS. Adjuvant treatment resulted in significantly better OS in patients with high-risk features.

AB - Chronic Kidney Disease affects approximately 10% of the world's adult population: it is within the top 20 causes of death worldwide, and its impact on patients and their families can be devastating. World Kidney Day and International Women's Day in 2018 coincide, thus offering an opportunity to reflect on the importance of women's health and specifically their kidney health, on the community, and the next generations, as well as to strive to be more curious about the unique aspects of kidney disease in women so that we may apply those learnings more broadly. Girls and women, who make up approximately 50% of the world's population, are important contributors to society and their families. Gender differences continue to exist around the world in access to education, medical care, and participation in clinical studies. Pregnancy is a unique state for women, offering an opportunity for diagnosis of kidney disease, but also a state where acute and chronic kidney diseases may manifest, and which may impact future generations with respect to kidney health. There are various autoimmune and other conditions that are more likely to impact women with profound consequences for child bearing, and on the fetus. Women have different complications on dialysis than men, and are more likely to be donors than recipients of kidney transplants. In this editorial, we focus on what we do and do not know about women, kidney health, and kidney disease, and what we might learn in the future to improve outcomes worldwide. PMID- 29464530 TI - Difference in regional neural fluctuations and functional connectivity in Crohn's disease: a resting-state functional MRI study. AB - Patients with Crohn's disease (CD) are shown to have abnormal changes in brain structures. This study aimed to further investigate whether these patients have abnormal brain activities and network connectivity. Sixty patients with CD and 40 healthy controls (HCs) underwent resting-state functional magnetic resonance imaging (fMRI) scans. Amplitude of low-frequency fluctuation (ALFF) and seed based functional connectivity (FC) were used to assess differences in spontaneous regional brain activity and functional connectivity. Compared to the HCs, patients with CD showed significantly higher ALFF values in hippocampus and parahippocampus (HIPP/paraHIPP), anterior cingulate cortex, insula, superior frontal cortex and precuneus. The ALFF values were significantly lower in secondary somatosensory cortex (S2), precentral gyrus, and medial prefrontal cortex. Functional connectivities between left HIPP and left inferior temporal cortex, and right middle cingulate cortex, HIPP, and fusiform area were significantly lower. The functional connectivities between right HIPP and right inferior orbitofrontal cortex and left HIPP were also significantly lower. Patients with CD showed higher or lower spontaneous activity in multiple brain regions. Altered activities in these brain regions may collectively reflect abnormal function and regulation of visceral pain and sensation, external environmental monitoring, and cognitive processing in these patients. Lower functional connectivity of the hippocampus-limbic system was observed in these patients. These findings may provide more information to elucidate the neurobiological mechanisms of the disease. PMID- 29464531 TI - The relationship between voxel-based metrics of resting state functional connectivity and cognitive performance in cognitively healthy elderly adults. AB - In previous studies, resting-state functional connectivity (FC) metrics of specific brain regions or networks based on prior hypotheses have been correlated with cognitive performance. Without constraining our analyses to specific regions or networks, we employed whole-brain voxel-based weighted degree (WD), a measure of local FC strength, to be correlated with three commonly used neuropsychological assessments of language, executive function and memory retrieval in both positive and negative directions in 67 cognitively healthy elderly adults. We also divided voxel-based WD into short-ranged and long-ranged WDs to evaluate the influence of FC distance on the WD-cognition relationship, and performed three validation tests. Our results showed that for language and executive function tests, positive WD correlates were located in the frontal and temporal cortices, and negative WD correlates in the precuneus and occipital cortices; for memory retrieval, positive WD correlates were located in the inferior temporal cortices, and negative WD correlates in the anterior cingulate cortices and supplementary motor areas. An FC-distance-dependent effect was also observed, with the short-ranged WD correlates of language and executive function tests located in the medial brain regions and the long-ranged WD correlates in the lateral regions. Our findings suggest that inter-individual differences in FC at rest are predictive of cognitive ability in the elderly adults. Moreover, the distinct patterns of positive and negative WD correlates of cognitive performance recapitulate the dichotomy between task-activated and task-deactivated neural systems, implying that a competition between distinct neural systems on functional network topology may have cognitive relevance. PMID- 29464532 TI - Contaminant exposure effects in a changing climate: how multiple stressors can multiply exposure effects in the amphipod Hyalella azteca. AB - Global climate change (GCC) is likely to intensify the synergistic effects between altered physicochemical parameters [of changing habitats] and other anthropogenic threats, such as water pollution, posing increased risks to aquatic biodiversity. As such, it is critical to understand how organisms will respond to changes in water temperature and salinity in the presence of contaminants. We exposed the epibenthic amphipod Hyalella azteca to a 3 * 3 factorial treatment design of three temperatures and three salinities ranging from 12 to 18 degrees C and 0 to 8 parts per thousand (ppt), respectively, in combination with a low level environmentally relevant concentration of the pyrethroid insecticide bifenthrin (1 ng/L). Effects on survival and swimming behavior were evaluated after 96 h exposure. Transcription of a select suite of genes was monitored at 24, 48, and 96 h using quantitative polymerase chain reaction (qPCR). Our results not only demonstrate that the changes in salinity and temperature result in negative effects to invertebrate survival, behavior, and gene response, but that the effects were significantly more pronounced in the presence of bifenthrin. This is particularly important since greater thermal fluctuations, changes in timing and extent of glacial melt, and changes in precipitation, could result in H. azteca experiencing lower temperatures at times that coincide with increased spraying of pyrethroids. These environmentally relevant exposures using the standard test species H. azteca provide essential information for understanding effects caused by GCC in conjunction with increasing pesticide use, further highlighting the need to incorporate GCC impacts into risk assessments of contaminants of concern. PMID- 29464533 TI - Photo-induced toxicity in early life stage fiddler crab (Uca longisignalis) following exposure to Deepwater Horizon oil. AB - The 2010 explosion of the Deepwater Horizon (DWH) oil rig led to the release of millions of barrels of oil in the Gulf of Mexico. Oil in aquatic ecosystems exerts toxicity through multiple mechanisms, including photo-induced toxicity following co-exposure with UV radiation. The timing and location of the spill coincided with both fiddler crab reproduction and peak yearly UV intensities, putting early life stage fiddler crabs at risk of injury due to photo-induced toxicity. The present study assessed sensitivity of fiddler crab larvae to photo induced toxicity during co-exposure to a range of environmentally relevant dilutions of high-energy water accommodated fractions of DWH oil, and either <10, 50, or 100% ambient sunlight, achieved with filters that allowed for variable UV penetration. Solar exposures (duration: 7-h per day) were conducted for two consecutive days, with a dark recovery period (duration: 17-h) in between. Survival was significantly decreased in treatments the presence of >10% UV and relatively low concentrations of oil. Results of the present study indicate fiddler crab larvae are sensitive to photo-induced toxicity in the presence of DWH oil. These results are of concern, as fiddler crabs play an important role as ecosystem engineers, modulating sediment biogeochemical processes via burrowing action. Furthermore, they occupy an important place in the food web in the Gulf of Mexico.

AB - PURPOSE: High expression of glioma-associated oncogene homolog-1 (GLI1) is associated with poor prognosis in estrogen receptor (ER) positive breast cancers. We sought to define a GLI1-dependent gene signature in ER-positive tumors that could further stratify patients at higher risk for disease recurrence and potentially lead to novel combination therapies. METHODS: We identified an inverse correlation between GLI1 expression and distant disease-free survival (DFS) using a dataset developed at MD Anderson Cancer Center (Hatzis dataset) containing clinical data from 508 breast cancer patients. Using a qPCR-based microarray platform, we identified genes differentially regulated by GLI1 in MCF7 cells and then determined if expression of these genes correlated with GLI1 expression in patient tumor samples. Statistical comparison between the groups was performed by ANOVA. Direct comparison of two groups was done by a two-tailed t test. Correlations between variables were done by Pearson's method. RESULTS: Expression of GLI1 and its target genes correlated significantly with worse distant DFS in breast cancer patients with Luminal A molecular subtype. Particularly, co-expression of GLI1 with EGFR and/or SNAI1, two of the identified GLI1 targets, was predictive of worse distant DFS in this subtype. Furthermore, patients with Luminal A tumors with a high GLI1 signature had a shorter distant DFS compared to the Luminal B subtype and the outcome for this group was comparable to patients with HER2-positive or basal-like tumors. CONCLUSION: We have identified a novel GLI1 gene signature that is associated with worse clinical outcomes among the patients with Luminal A subtype of breast cancer. PMID- 29464535 TI - Long-term survival and cure model following liver resection for breast cancer metastases. AB - INTRODUCTION: Long-term survival is still rarely achieved with current systemic treatment in patients with breast cancer liver metastases (BCLM). Extended survival after hepatectomy was examined in a select group of BCLM patients. PATIENTS AND METHODS: Hepatectomy for BCLM was performed in 139 consecutive patients between 1985 and 2012. Patients who survived < 5 years were compared to those who survived >= 5 years from first diagnosis of hepatic metastases. Predictive factors for survival were analyzed. Statistically cured, defined as those patients who their hazard rate returned to that of the general population, was analyzed. RESULTS: Of the 139, 43 patients survived >= 5 years. Significant differences between patient groups (< 5 vs. >= 5 years) were mean time interval between primary tumor and hepatic metastases diagnosis (50 vs. 43 months), mean number of resected tumors (3 vs. 2), positive estrogen receptors (54% vs. 79%), microscopic lymphatic invasion (65% vs. 34%), vascular invasion (63% vs. 37%), hormonal therapy after resection (34% vs. 74%), number of recurrence (40% vs. 65%) and repeat hepatectomy (1% vs. 42%), respectively. The probability of statistical cure was 14% (95% CI 1.4-26.7%) in these patients. CONCLUSIONS: Hepatectomy combined with systemic treatment can provide a chance of long-term survival and even cure in selected patients with BCLM. Microscopic vascular/lymphatic invasion appears to be a novel predictor for long-term survival after hepatectomy for BCLM and should be part of the review when discussing multidisciplinary treatment strategies. PMID- 29464536 TI - A Specialized Medical Management Program to Address Post-operative Weight Regain in Bariatric Patients. AB - INTRODUCTION: Although bariatric surgery results in massive weight loss, weight regain over time up to as much as 25% is not uncommon. Weight regain in this population often leads to long-term weight loss failure and non-compliance in clinical follow-up and program recommendations. METHODS: We analyzed early weight outcomes at 3 and 6 months of 48 bariatric patients referred to an individualized, multidisciplinary medical management program at the Center for Obesity Medicine (COM) to address weight regain in 2015 and compared to a group of matched non-bariatric patients. The medical management center, under the direction of a medical obesity specialist and complementary to the surgical program and multidisciplinary team, addressed weight regain with intensive lifestyle (diet, activity, anti-stress therapy, behavioral counseling, sleep) and with medical intervention (one or more anti-obesity medications). RESULTS: According to early findings, the average percentage post-operative weight regain of patients entering the weight management program was 20% above nadir and time since surgery averaged 6 years (range = 1 to 20 years) with a mean weight loss of - 2.3 kg after 3 months and - 4.4 kg at 6 months into the program. Individuals most successful with weight loss were those treated with anorexigenic pharmaceuticals. Weight and percent weight loss were significantly greater for the non-surgical than the surgical patients at 3 and 6 months (p < 0.05). CONCLUSIONS: A medically supervised weight management program complementary to surgery is beneficial for the treatment of weight regain and may prove important in assisting the surgical patient achieve long-term weight loss success.

PMID- 29464538 TI - Temperament Moderators of Prospective Associations Between Community Violence Exposure and Urban African American Adolescents' Aggressive Behavior. AB - Research suggests that neighborhood risks are associated with internalizing symptoms for adolescents high on temperament characteristics related to the behavioral inhibition system (BIS). However, it is unclear whether newer conceptualizations of the BIS distinguishing fear from anxiety operate similarly. Furthermore, it is unclear whether the BIS attenuates community violence exposure effects on externalizing problems. The current study examined whether the BIS or the fight-flight-freeze system (FFFS) moderated associations between community violence exposure and internalizing and externalizing problems. Participants were 367 urban African American adolescents who reported on temperament characteristics in grade 9, and community violence exposure and adjustment problems in grades 9 and 10. Hierarchical linear regression analyses indicated that the FFFS, but not the BIS, moderated the association between community violence exposure and aggressive behavior. Grade 9 community violence exposure was positively associated with grade 10 aggression for adolescents low on FFFS, suggesting that the FFFS may partly differentiate community violence-exposed adolescents' aggressive behavior.

AB - Coccidiosis endemicity remains a major challenge in poultry production in the tropics and all over the world. In order to develop predictive tool for identification of chickens that are at risk of coccidiosis among Nigerian indigenous chickens, body weight gain (BWG) and hematological variables were determined for chickens infected with Eimeria tenella (female = 60, male = 63) and uninfected (female = 51, male = 45). The hematological variables analyzed include the following: packed cell volume (PCV, %), white blood cells (WBC, * 106/MUl), and red blood cells (RBC, * 106/MUl), as well as differential leucocyte percentages of neutrophils, lymphocytes, monocytes, and eosinophils. Body weight gain was determined at days 3, 6, 9, 12, and 15. Of the 12 variables analyzed, BWG at day 3, monocyte, PCV, and WBC in males and BWG at days 6, 9, and 12, PCV, and WBC in female chickens showed significant (P <= 0.01) difference between the infected and uninfected. Stepwise discriminant analysis evolved a model that could distinguish uninfected from Eimeria-infected chickens. Packed cell volume, WBC, BWG at day 3, and lymphocytes emerged the most discriminant between uninfected and Eimeria-infected chickens in male chickens. In female chickens, PCV, RBC, and BWG at day 3 were identified as most discriminant variables in separating the uninfected from Eimeria-infected chickens. Therefore, this study suggests that routine blood test and estimates of body weight gain could serve as a useful tool for identifying chickens that may be at risk of coccidiosis, enabling improvement of preventive measures. PMID- 29464540 TI - Genetic analysis of persistency in HF crossbred cattle at an organized farm of northern India. AB - The present study was undertaken to estimate effect of various genetic and non genetic factors on persistency of milk production and to identify the most appropriate persistency method that fits best in our environment. In the present study, effects of different non-genetic factors, viz. year, season, days to attain peak yield, and genetic group based on the level of exotic inheritance on persistency of milk yield in crossbred cattle were studied. Data comprised of 686 first lactation daily milk yield records of crossbred cattle that were maintained at GADVASU dairy farm over a period of 25 years from 1991 to 2015 were utilized to calculate persistency coefficients by four methods, viz., Ludwick and Peterson method (P1), Mahadevan method (P2), ratio method (P3), and Prasad et al. method (P4). Overall least squares means for persistency by Ludwick and Peterson method (P1), Mahadevan method (P2), ratio method (P3), and Prasad et al. method (P4) were 0.896 +/- 0.096, 1.385 +/- 0.224, 187.207 +/- 26.398, and 0.621 +/- 0.098, respectively. Effect of sires was significant (P < 0.05) on P2 and P4 methods. Effect of genetic group on all four methods was non-significant. Period of calving had significant (P < 0.01) effect on persistency of milk yield (P2, P3, and P4 methods). Effect of season of calving on persistency of milk yield was found to be significant in all estimates obtained by the four methods. Summer and autumn calvers were most persistent whereas spring and winter calvers were least persistent for (P2, P3, and P4 methods). Persistency of milk yield was significantly (P < 0.05) affected by days to attain peak yield in P1 and P2 methods. Maximum persistency was obtained in animals attaining peak at 41-57 days of lactation and minimum in < 41 days for Mahadevan method and ratio method. The highest heritability of persistency and minimum value of standard error was estimated as 0.275 +/- 0.11 for the Mahadevan method followed by the Prasad method (0.197 +/- 0.10) by half sib correlation method. The maximum coefficient of variation which indicates available variability was estimated as 20.788% for persistency by the Mahadevan method followed by 18.969% for the Prasad method. The highest correlation was also observed between P1 and P3 methods by Spearman's and Pearson's correlation for least squares breeding value of the sires. On the basis of heritability, standard error of heritability, and coefficient of variation, it can be concluded that the Mahadevan method followed by the Prasad method suits best to our environment for animals in first lactation as well as they can be utilized for effective selection for higher persistency in crossbred animals of Punjab. PMID- 29464541 TI - Sero-prevalence of chlamydiosis in cattle and selected wildlife species at a wildlife/livestock interface area of Zimbabwe. AB - A study was conducted to investigate the seroprevalence and associated risk factors of Chlamydia abortus infection in cattle and some selected wildlife species at selected interface areas at the periphery of the Great Limpopo Transfrontier Conservation Area in Zimbabwe. Three study sites were selected based on the type of livestock-wildlife interface, porous livestock-wildlife interface (unrestricted), non-porous livestock-wildlife interface (restricted by fencing), and livestock-wildlife non-interface (totally absent or control). Sera were collected from cattle aged >= 2 years representing both female and intact male. Sera were also collected from selected wild ungulates from Mabalauta (porous interface) and Chipinda Pools (non-interface) areas of the Gonarezhou National Park. Sera were tested for antibodies to Chlamydia abortus using a CFT. A X 2 test was used to assess differences between categories and p < 0.05 was considered as significant. In cattle, the overall seroprevalence was 32.7% (327/1011; 95% CI 29.5-35.3). A significantly lower seroprevalence was recorded for the porous interface (24.2%) compared to the non-porous (42.5%) (p < 0.0001) and the non-interface (36.2%) (p = 0.001). Overall, the wet season recorded a significantly (p = 0.015) higher seroprevalence than the dry season. In wildlife, antibodies were detected in buffaloes (47.7%) and impalas (43.8%) but not in kudus. Buffaloes from Chipinda Pools (53.4%) had a significantly (p = 0.036) higher seroprevalence than those from Mabalauta (26.1%). The results established the presence of chlamydiosis in cattle and selected wildlife and that independent infections may be maintained in buffalo populations. Further studies are required to clarify chlamydiae circulating between cattle and wildlife. PMID- 29464542 TI - Streptomyces tunisialbus sp. nov., a novel Streptomyces species with antimicrobial activity. AB - A novel actinomycete strain designated S2T was isolated from Tunisian rhizosphere soil of Lavandula officinalis. This isolate exhibited broad spectrum antibacterial activity against several Gram-positive and Gram-negative bacteria and also antifungal activity against yeast and filamentous fungi. The isolate S2T presents morphological and chemotaxonomic characteristics typical of the members of the genus Streptomyces. Whole cell hydrolysates of S2T were found to contain LL-diaminopimelic acid. The major fatty acids were identified as C16:0, anteiso C15:0 and iso-C16:0 whereas the predominant menaquinones were found to be MK 9(H6) and MK-9(H8). The polar lipids were identified as diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside and three unidentified compounds. The G+C content of the genomic DNA was determined to be 71.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain S2T belongs to the genus Streptomyces and is closely related to Streptomyces netropsis DSM 40259T with 99.86% sequence similarity. Multi-locus sequence analysis (MLSA) based on four house-keeping gene alleles (gyrB, recA, trpB, rpoB) showed that isolate S2T is closely related to S. netropsis, with an MLSA distance greater than 0.007. The DNA-DNA relatedness between strain S2T and its near phylogenetic neighbour was 63.6 +/- 2.3%, which is lower than the 70% threshold value for delineation of genomic prokaryotic species. This isolate was also distinguished from the type strain S. netropsis DSM 40259T, using a combination of morphological and physiological features. Based on its phenotypic and molecular properties, strain S2T is considered to represent a novel species of the genus Streptomyces, for which the name Streptomyces tunisialbus sp. nov. is proposed. The type strain is S2T (= JCM 32165T = DSM 105760T).

AB - The use of MALDI MS as a fast and direct method to detect the Abeta oligomers of different masses is examined in this paper. Experimental results suggest that Abeta oligomers are ionized and detected as singly charged ions, and thus, the resulting mass spectrum directly reports the oligomer size distribution. Validation experiments were performed to verify the MS data against artifacts. Mass spectra collected from modified Abeta peptides with different propensities for aggregation were compared. Generally, the relative intensities of multimers were higher from samples where oligomerization was expected to be more favorable, and vice versa. MALDI MS was also able to detect the differences in oligomeric composition before and after the incubation/oligomerization step. Such differences in sample composition were also independently confirmed with an in vitro Abeta toxicity study on primary rat cortical neurons. An additional validation was accomplished through removal of oligomers from the sample using molecular weight cutoff filters; the resulting MS data correctly reflected the removal at the expected cutoff points. The results collectively validated the ability of MALDI MS to assess the monomeric/multimeric composition of Abeta samples. Graphical Abstract ?. PMID- 29464544 TI - Top Down Tandem Mass Spectrometric Analysis of a Chemically Modified Rough-Type Lipopolysaccharide Vaccine Candidate. AB - Recent advances in lipopolysaccharide (LPS) biology have led to its use in drug discovery pipelines, including vaccine and vaccine adjuvant discovery. Desirable characteristics for LPS vaccine candidates include both the ability to produce a specific antibody titer in patients and a minimal host inflammatory response directed by the innate immune system. However, in-depth chemical characterization of most LPS extracts has not been performed; hence, biological activities of these extracts are unpredictable. Additionally, the most widely adopted workflow for LPS structure elucidation includes nonspecific chemical decomposition steps before analyses, making structures inferred and not necessarily biologically relevant. In this work, several different mass spectrometry workflows that have not been previously explored were employed to show proof-of-principle for top down LPS primary structure elucidation, specifically for a rough-type mutant (J5) E. coli-derived LPS component of a vaccine candidate. First, ion mobility filtered precursor ions were subjected to collision induced dissociation (CID) to define differences in native J5 LPS v. chemically detoxified J5 LPS (dLPS). Next, ultra-high mass resolving power, accurate mass spectrometry was employed for unequivocal precursor and product ion empirical formulae generation. Finally, MS3 analyses in an ion trap instrument showed that previous knowledge about dissociation of LPS components can be used to reconstruct and sequence LPS in a top down fashion. A structural rationale is also explained for differential inflammatory dose-response curves, in vitro, when HEK-Blue hTLR4 cells were administered increasing concentrations of native J5 LPS v. dLPS, which will be useful in future drug discovery efforts. Graphical Abstract ?. PMID- 29464545 TI - Extra-mucosal enucleation is still a safe and feasible treatment option of giant esophageal leiomyomas. AB - Esophageal leiomyoma (EL) is rare but still the most common benign tumor of the esophagus. Extra-mucosal enucleation (EME) is the treatment of choice. Many recent reports have favored esophageal resection for giant Esophageal leiomyomas (ELs). The consequence of esophageal resection is well known and it would be radical to consider it as a preferred treatment for giant EL since most of them are still benign. We share case series of five giant ELs managed by EME, avoiding a mucosal breach and hence avoiding potentially morbid esophageal resections. PMID- 29464546 TI - Gene-diet-related factors of hyperglycaemia in postmenopausal women. AB - As ageing and increased body fat are the signs of insulin resistance, we have studied whether the presence of Pro12Ala and C1431T of peroxisome proliferator activated receptor gamma 2 gene and Trp64Arg of beta 3-adrenergic receptor gene may predispose to the hyperglycaemia development in postmenopausal women, who have never undergone hypoglycaemic treatment. The distributions of selected allele and genotype frequencies were determined by the PCR-RFLP method in normo- and hyperglycaemic, who have never been diagnosed and treated for diabetes mellitus were measured. The amount of body fat and lean body mass (LBM) were assessed by the bioimpedance method and nutritional habits by 7-day dietary recall. There were no differences between the distribution of genotypes and the allele frequencies of the Pro12Ala, C1431T and Trp64Arg polymorphisms in normo- and hyperglycaemic women. Hyperglycaemic women were characterized by visceral obesity, hypertension, higher serum insulin and triglycerides, higher intake of fat and lower consumption of complex carbohydrates and B vitamins. Normoglycaemic women with Pro12Pro polymorphism acquired higher energy from dietary fat (p < 0.0276) and lower energy from carbohydrates (p < 0.0480) than normoglycaemic Ala12 carriers. Subjects with Pro12Pro polymorphism and LBM > 58% of total body mass or with Trp64Trp and normal triglycerides have higher chance of normoglycaemia. Genotyping for Pro12Ala and Trp64Arg polymorphism in postmenopausal women may have the clinical benefit of predicting hyperglycaemia, thereby contributing to the prevention of diabetes mellitus development in the future. However, not only the genetic background but also the dietary habits (intake of fat, carbohydrates and B vitamins) determine the risk of hyperglycaemia. PMID- 29464547 TI - Comparative evaluation of technetium-99m-diethylenetriaminepentaacetic acid renal dynamic imaging versus the Modification of Diet in Renal Disease equation and the Chronic Kidney Disease Epidemiology Collaboration equation for the estimation of GFR. AB - PURPOSE: We compared the performance of technetium-99m diethylenetriaminepentaacetic acid (99mTc-DTPA) renal dynamic imaging (RDI), the MDRD equation, and the CKD EPI equation to estimate glomerular filtration rate (GFR). METHODS: A total of 551 subjects, including CKD patients and healthy individuals, were enrolled in this study. Dual plasma sample clearance method of 99mTc-DTPA was used as the true value for GFR (tGFR). RDI and the MDRD and CKD EPI equations for estimating GFR were compared and evaluated. RESULTS: Data indicate that RDI and the MDRD equation underestimated GFR and CKD EPI overestimated GFR. RDI was associated with significantly higher bias than the MDRD and CKD EPI equations. The regression coefficient, diagnostic precision, and consistency of RDI were significantly lower than either equation. RDI and the MDRD equation underestimated GFR to a greater degree in subjects with tGFR >= 90 ml/min/1.73 m2 compared with the results obtained from all subjects. In the tGFR60-89 ml/min/1.73 m2 group, the precision of RDI was significantly lower than that of both equations. In the tGFR30-59 ml/min/1.73 m2 group, RDI had the least bias, the most precision, and significantly higher accuracy compared with either equation. In tGFR < 30 ml/min/1.73 m2, the three methods had similar performance and were not significantly different. CONCLUSIONS: RDI significantly underestimates GFR and performs no better than MDRD and CKD EPI equations for GFR estimation; thus, it should not be recommended as a reference standard against which other GFR measurement methods are assessed. However, RDI better estimates GFR than either equation for individuals in the tGFR30-59 ml/min/1.73 m2 group and thus may be helpful to distinguish stage 3a and 3b CKD. PMID- 29464548 TI - Leptin Involvement in Primary Brain and Pituitary Tumors: Therapeutic Potential, Prognostic Value, and Proposed Diagnostic Application. AB - Brain tumors are associated with increased mortality and morbidity and are the most common cancer type in children and young adults. The present review focuses on the interplay between leptin, the most extensively studied adipokine, and the onset, development, and treatment of primary brain and intracranial tumors. The two main mechanisms for increased leptin levels in intracranial tumor survivors, leptin resistance caused by hypothalamic damage, or secondary to obesity, are discussed. The contradicting mechanistic observations on leptin being able to both promote tumorinogenesis (e.g., in gliomas) as well as inhibit it (e.g., in adenomas) are also reported. Additionally, the relevant current and future clinical applications, including most notably the proposed use of serum leptin measurements for non-invasive brain tumor diagnostics, are also reported. PMID- 29464549 TI - Exploring Preconception Care: Insurance Status, Race/Ethnicity, and Health in the Pre-pregnancy Period. AB - Objective To measure the association of preconception health insurance status with preconception health among women in New York City, and examine whether this association is modified by race/ethnicity. Methods Using data from the New York City Pregnancy Risk Assessment Monitoring System 2009-2011 (n = 3929), we created a "Preconception Health Score" (PHS) capturing modifiable behaviors, healthcare services utilization, pregnancy intention, and timely entry into prenatal care. We then built multivariable logistic regression models to measure the association of PHS with health insurance status and race/ethnicity. Results We found PHS to be higher among women with private insurance (7.3 +/- 0.07) or public insurance (6.3 +/- 0.08) before pregnancy than no insurance (5.9 +/- 0.09) (p < .001). However, when stratified by race/ethnicity, the positive association of PHS with insurance was absent in the non-white population. Conclusions for Practice Having health insurance during the pre-pregnancy period is associated with greater health among white women, but not among black or Hispanic women in NYC. PMID- 29464551 TI - Immunohistochemical Assessment of the Expression of Biliary Transportation Proteins MRP2 and MRP3 in Hepatocellular Carcinoma and in Cholangiocarcinoma. AB - Multidrug resistance-associated protein 2 (MRP2) is a multi-specific organic anion transporter predominantly expressed in the canalicular membrane of hepatocytes, epithelial cells from gallbladder and apical membranes of proximal tubular kidney epithelium whereas multidrug resistance-associated protein 3 (MRP3) is present in the basolateral membrane of hepatocytes and cholangiocytes. This study aims to detect the expression of these transporters in hepatocellular carcinoma (HCC) and in cholangiocarcinoma (CC), searching for evidences for future studies on differential diagnosis and on clinical essays. The immunohistochemical reactivity (IHC) of these transporters was assessed in tissue microarrays of 80 HCC and 56 CC cases using monoclonal antibodies and compared with anatomopathological (AP) variables. The positivity of MRP2 was observed in 92.3% of HCC and in 96.3% of CC. The detection of high MRP2 expression in HCC was not significantly different (p > 0.05) according to the size, number of nodules architectural pattern and growth pattern of HCC and CC. Regarding histological grades, 22/22 well moderately differentiated HCC versus 50/56 poorly differentiated HCC were positive for MRP2. A trend for lower expression in poor differentiation HCC was found. And 50/50 well/moderately differentiated CC versus 2/4 poorly/undifferentiated CC were positive for MRP2. This result showed a reduced expression (p = 0,0004) in poorly differentiated CC. MRP3 positivity was observed in 18.8% of HCC and was not significantly different according to AP parameters. MRP3 was expressed in 44.5% CC, with a trend for lower expression in less differentiated CC and significantly lower rates in the ductular histological subtype (p = 0.023). The high expression of MRP2 in HCC and in CC is conserved regardless most of the anatomopathological parameters, except for a trend of lower expression in less differentiated HCC and CC. The observation of lower MRP3 expression in less differentiated CC and, especially, in the histological subtype with expression of hepatic progenitor cell phenotypes leads to future opportunities to evaluate the expression of this marker in cholangiocarcinomas. PMID- 29464550 TI - Clinical Pharmacokinetics and Pharmacodynamics of Drugs in the Central Nervous System. AB - Despite contributing significantly to the burden of global disease, the translation of new treatment strategies for diseases of the central nervous system (CNS) from animals to humans remains challenging, with a high attrition rate in the development of CNS drugs. The failure of clinical trials for CNS therapies can be partially explained by factors related to pharmacokinetics/pharmacodynamics (PK/PD), such as lack of efficacy or improper selection of the initial dosage. A focused assessment is needed for CNS-acting drugs in first-in-human studies to identify the differences in PK/PD from animal models, as well as to choose the appropriate dose. In this review, we summarize the available literature from human studies on the PK and PD in brain tissue, cerebrospinal fluid, and interstitial fluid for drugs used in the treatment of psychosis, Alzheimer's disease and neuro-HIV, and address critical questions in the field. We also explore newer methods to characterize PK/PD relationships that may lead to more efficient dose selection in CNS drug development. PMID- 29464552 TI - Neural response to prosocial scenes relates to subsequent giving behavior in adolescents: A pilot study. AB - Adolescence is characterized by extensive neural development and sensitivity to social context, both of which contribute to engaging in prosocial behaviors. Although it is established that prosocial behaviors are linked to positive outcomes in adulthood, little is known about the neural correlates of adolescents' prosociality. Identifying whether the brain is differentially responsive to varying types of social input may be important for fostering prosocial behavior. We report pilot results using new stimuli and an ecologically valid donation paradigm indicating (1) brain regions typically recruited during socioemotional processing evinced differential activation when adolescents evaluated prosocial compared with social or noninteractive scenes (N = 20, ages 13-17 years, MAge = 15.30 years), and (2) individual differences in temporoparietal junction recruitment when viewing others' prosocial behaviors were related to adolescents' own charitable giving. These novel findings have significant implications for understanding how the adolescent brain processes prosocial acts and for informing ways to support adolescents to engage in prosocial behaviors in their daily lives. PMID- 29464553 TI - Heart work after errors: Behavioral adjustment following error commission involves cardiac effort. AB - Posterror slowing (PES) is the observation that people respond slower on trials subsequent to error commissions than on trials subsequent to correct responses. Different accounts have been proposed to explain PES. On the one hand, it has been suggested that PES arises from an adaptive increase in cognitive control following error commission, thereby making people more cautious after making an error. On the other hand, PES has been attributed to an orienting response, indicating that attention is shifted toward the error. In the present study we tested these accounts by investigating the effects of error commission in both flanker and switch tasks on two task-evoked cardiac measures: the interbeat interval-that is, the interval between two consecutive R peaks-and the RZ interval-that is, the interval between the R peak and the Z point-as measured using electro- and impedance cardiography, respectively. These measures allowed us to measure cardiac deceleration (autonomic orienting) and cardiac effort mobilization, respectively. Our results revealed a shorter RZ interval during posterror trials, indicating increased effort mobilization following errors. In addition, we replicated earlier studies that have shown cardiac slowing during error trials. However, multilevel analyses showed that only the posterror decrease in RZ interval predicted posterror reaction times, whereas there was no positive relationship between error-related cardiac deceleration and posterror reaction times. Our results suggest that PES is related to increased cardiac effort, supporting a cognitive-control account of PES. PMID- 29464554 TI - The influence of self-construals on the ERP response to the rewards for self and mother. AB - Individual self-construal (independent vs. interdependent) could be temporarily modulated by the priming effect. Our previous studies have found that when Chinese participants gambled for mother and for self, outcome feedback evoked comparable neural responses between two conditions. However, it remains unclear if the response to rewards for mother and for self would differ after independence self-construal priming. In this study, we manipulated participants' self-construal (independent vs. interdependent) before a simple gambling task. The event-related potential (ERP) results reveal that when an interdependent self construal was primed, the participants exhibited a comparable feedback-related negativity (FRN) elicited by outcome feedback for self and for mother. In contrast, independent self-construal priming resulted in a greater FRN elicited by outcome feedback for self than for mother. Meanwhile, the P3 component was insensitive to self-construal manipulation. These findings indicate the modulation effect of self-construal priming on the response to rewards for others. PMID- 29464555 TI - Bacterial Adhesion Pili. AB - Escherichia coli bacterial cells produce multiple types of adhesion pili that mediate cell-cell and cell-host attachments. These pili (also called 'fimbriae') are large biopolymers that are comprised of subunits assembled via a sophisticated micro-machinery into helix-like structures that are anchored in the bacterial outer membrane. They are commonly essential for initiation of disease and thus provide a potential target for antibacterial prevention and treatment. To develop new therapeutics for disease prevention and treatment we need to understand the molecular mechanisms and the direct role of adhesion pili during pathogenesis. These helix-like pilus structures possess fascinating and unique biomechanical properties that have been thoroughly investigated using high resolution imaging techniques, force spectroscopy and fluid flow chambers. In this chapter, we first discuss the structure of pili and the micro-machinery responsible for the assembly process. Thereafter, we present methods for measurement of the biomechanics of adhesion pili, including optical tweezers. Data demonstrate unique biomechanical properties of pili that allow bacteria to sustain binding during in vivo fluid shear forces. We thereafter summarize the current biomechanical findings related to adhesion pili and show that pili biomechanical properties are niche-specific. That is, the data suggest that there is an organ-specific adaptation of pili that facilitates infection of the bacteria's target tissue. Thus, pilus biophysical properties are an important part of Escherichia coli pathogenesis, allowing bacteria to overcome hydrodynamic challenges in diverse environments. PMID- 29464556 TI - Microbial Rhodopsins. AB - Microbial rhodopsins (MRs) are a large family of photoactive membrane proteins, found in microorganisms belonging to all kingdoms of life, with new members being constantly discovered. Among the MRs are light-driven proton, cation and anion pumps, light-gated cation and anion channels, and various photoreceptors. Due to their abundance and amenability to studies, MRs served as model systems for a great variety of biophysical techniques, and recently found a great application as optogenetic tools. While the basic aspects of microbial rhodopsins functioning have been known for some time, there is still a plenty of unanswered questions. This chapter presents and summarizes the available knowledge, focusing on the functional and structural studies.

In the case of cyanobacteria and red-algae, photosynthetic organisms found in a wide variety of ecological niches, the major antenna is called the Phycobilisome (PBS). The PBS has many unique characteristics that sets it apart from the antenna complexes of other organisms (bacteria, algae and plants). These differences include the type of light absorbing chromophores, the protein environment of the chromophores, the method of assembly and association and the intercellular location with respect to the photosynthetic reaction centers (RCs). Since the final goal of all antenna complexes is the same - controlled absorption and transfer of the energy of the sun to the RCs, the unique structural and chemical differences of the PBS also require unique energy transfer mechanisms and pathways. In this review we will describe in detail the structural facets that lead to a mature PBS, followed by an attempt to understand the energy transfer properties of the PBS as they have been measured experimentally. PMID- 29464558 TI - Bacterial Mechanosensitive Channels. AB - Mechanosensitive (MS) channels protect bacteria against hypo-osmotic shock and fulfil additional functions. Hypo-osmotic shock leads to high turgor pressure that can cause cell rupture and death. MS channels open under these conditions and release unspecifically solutes and consequently the turgor pressure. They can recognise the raised pressure via the increased tension in the cell membrane. Currently, a better understanding how MS channels can sense tension on molecular level is developing because the interaction of the lipid bilayer with the channel is being investigated in detail. The MS channel of large conductance (MscL) and of small conductance (MscS) have been distinguished and studied in molecular detail. In addition, larger channels were found that contain a homologous region corresponding to MscS so that MscS represents a family of channels. Often several members of this family are present in a species. The importance of this family is underlined by the fact that members can be found not only in bacteria but also in higher organisms. While MscL and MscS have been studied for years in particular by electrophysiology, mutagenesis, molecular dynamics, X-ray crystallography and other biophysical techniques, only recently more details are emerging about other members of the MscS-family. PMID- 29464559 TI - Monoamine Oxidases. AB - Monoamine oxidases A and B (MAO A and B) are mammalian flavoenzymes bound to the outer mitochondrial membrane. They were discovered almost a century ago and they have been the subject of many biochemical, structural and pharmacological investigations due to their central role in neurotransmitter metabolism. Currently, the treatment of Parkinson's disease involves the use of selective MAO B inhibitors such as rasagiline and safinamide. MAO inhibition was shown to exert a general neuroprotective effect as a result of the reduction of oxidative stress produced by these enzymes, which seems to be relevant also in non-neuronal contexts. MAOs were successfully expressed as recombinant proteins in Pichia pastoris, which allowed a thorough biochemical and structural characterization. These enzymes are characterized by a globular water-soluble main body that is anchored to the mitochondrial membrane through a C-terminal alpha-helix, similar to other bitopic membrane proteins. In both MAO A and MAO B the enzyme active site consists of a hydrophobic cavity lined by residues that are conserved in the two isozymes, except for few details that determine substrate and inhibitor specificity. In particular, human MAO B features a dual-cavity active site whose conformation depends on the size of the bound ligand. This article provides a comprehensive and historical review of MAOs and the state-of-the-art of these enzymes as membrane drug targets. PMID- 29464561 TI - Mitochondrial Respiratory Chain Complexes. AB - Mitochondria are the power stations of the eukaryotic cell, using the energy released by the oxidation of glucose and other sugars to produce ATP. Electrons are transferred from NADH, produced in the citric acid cycle in the mitochondrial matrix, to oxygen by a series of large protein complexes in the inner mitochondrial membrane, which create a transmembrane electrochemical gradient by pumping protons across the membrane. The flow of protons back into the matrix via a proton channel in the ATP synthase leads to conformational changes in the nucleotide binding pockets and the formation of ATP. The three proton pumping complexes of the electron transfer chain are NADH-ubiquinone oxidoreductase or complex I, ubiquinone-cytochrome c oxidoreductase or complex III, and cytochrome c oxidase or complex IV. Succinate dehydrogenase or complex II does not pump protons, but contributes reduced ubiquinone. The structures of complex II, III and IV were determined by x-ray crystallography several decades ago, but complex I and ATP synthase have only recently started to reveal their secrets by advances in x-ray crystallography and cryo-electron microscopy. The complexes I, III and IV occur to a certain extent as supercomplexes in the membrane, the so-called respirasomes. Several hypotheses exist about their function. Recent cryo-electron microscopy structures show the architecture of the respirasome with near-atomic detail. ATP synthase occurs as dimers in the inner mitochondrial membrane, which by their curvature are responsible for the folding of the membrane into cristae and thus for the huge increase in available surface that makes mitochondria the efficient energy plants of the eukaryotic cell. PMID- 29464560 TI - Transient Receptor Potential (TRP) Channels. AB - Transient Receptor Potential (TRP) channels are evolutionarily conserved integral membrane proteins. The mammalian TRP superfamily of ion channels consists of 28 cation permeable channels that are grouped into six subfamilies based on sequence homology (Fig. 6.1). The canonical TRP (TRPC) subfamily is known for containing the founding member of mammalian TRP channels. The vanilloid TRP (TRPV) subfamily has been extensively studied due to the heat sensitivity of its founding member. The melastatin-related TRP (TRPM) subfamily includes some of the few known bi functional ion channels, which contain functional enzymatic domains. The ankyrin TRP (TRPA) subfamily consists of a single chemo-nociceptor that has been proposed to be a target for analgesics. The mucolipin TRP (TRPML) subfamily channels are found primarily in intracellular compartments and were discovered based on their critical role in type IV mucolipidosis (ML-IV). The polycystic TRP (TRPP) subfamily is a diverse group of proteins implicated in autosomal dominant polycystic kidney disease (ADPKD). Overall, this superfamily of channels is involved in a vast array of physiological and pathophysiological processes making the study of these channels imperative to our understanding of subcellular biochemistry. PMID- 29464562 TI - The SarcoEndoplasmic Reticulum Calcium ATPase. AB - The calcium pump (a.k.a. Ca2+-ATPase or SERCA) is a membrane transport protein ubiquitously found in the endoplasmic reticulum (ER) of all eukaryotic cells. As a calcium transporter, SERCA maintains the low cytosolic calcium level that enables a vast array of signaling pathways and physiological processes (e.g. synaptic transmission, muscle contraction, fertilization). In muscle cells, SERCA promotes relaxation by pumping calcium ions from the cytosol into the lumen of the sarcoplasmic reticulum (SR), the main storage compartment for intracellular calcium. X-ray crystallographic studies have provided an extensive understanding of the intermediate states that SERCA populates as it progresses through the calcium transport cycle. Historically, SERCA is also known to be regulated by small transmembrane peptides, phospholamban (PLN) and sarcolipin (SLN). PLN is expressed in cardiac muscle, whereas SLN predominates in skeletal and atrial muscle. These two regulatory subunits play critical roles in cardiac contractility. While our understanding of these regulatory mechanisms are still developing, SERCA and PLN are one of the best understood examples of peptide transporter regulatory interactions. Nonetheless, SERCA appeared to have only two regulatory subunits, while the related sodium pump (a.k.a. Na+, K+-ATPase) has at least nine small transmembrane peptides that provide tissue specific regulation. The last few years have seen a renaissance in our understanding of SERCA regulatory subunits. First, structures of the SERCA-SLN and SERCA-PLN complexes revealed molecular details of their interactions. Second, an array of micropeptides concealed within long non-coding RNAs have been identified as new SERCA regulators. This chapter will describe our current understanding of SERCA structure, function, and regulation. PMID- 29464563 TI - Organization of Plant Photosystem II and Photosystem I Supercomplexes. AB - In nature, plants are continuously exposed to varying environmental conditions. They have developed a wide range of adaptive mechanisms, which ensure their survival and maintenance of stable photosynthetic performance. Photosynthesis is delicately regulated at the level of the thylakoid membrane of chloroplasts and the regulatory mechanisms include a reversible formation of a large variety of specific protein-protein complexes, supercomplexes or even larger assemblies known as megacomplexes. Revealing their structures is crucial for better understanding of their function and relevance in photosynthesis. Here we focus our attention on the isolation and a structural characterization of various large protein supercomplexes and megacomplexes, which involve Photosystem II and Photosystem I, the key constituents of photosynthetic apparatus. The photosystems are often attached to other protein complexes in thylakoid membranes such as light harvesting complexes, cytochrome b 6 f complex, and NAD(P)H dehydrogenase. Structural models of individual supercomplexes and megacomplexes provide essential details of their architecture, which allow us to discuss their function as well as physiological significance. PMID- 29464564 TI - The Cytochrome b 6 f Complex: Biophysical Aspects of Its Functioning in Chloroplasts. AB - This chapter presents an overview of structural properties of the cytochrome (Cyt) b 6 f complex and its functioning in chloroplasts. The Cyt b 6 f complex stands at the crossroad of photosynthetic electron transport pathways, providing connectivity between Photosystem (PSI) and Photosysten II (PSII) and pumping protons across the membrane into the thylakoid lumen. After a brief review of the chloroplast electron transport chain, the consideration is focused on the structural organization of the Cyt b 6 f complex and its interaction with plastoquinol (PQH2, reduced form of plastoquinone), a mediator of electron transfer from PSII to the Cyt b 6 f complex. The processes of PQH2 oxidation by the Cyt b 6 f complex have been considered within the framework of the Mitchell's Q-cycle. The overall rate of the intersystem electron transport is determined by PQH2 turnover at the quinone-binding site Qo of the Cyt b 6 f complex. The rate of PQH2 oxidation is controlled by the intrathylakoid pHin, which value determines the protonation/deprotonation events in the Qo-center. Two other regulatory mechanisms associated with the Cyt b 6 f complex are briefly overviewed: (i) redistribution of electron fluxes between alternative (linear and cyclic) pathways, and (ii) "state transitions" related to redistribution of solar energy between PSI and PSII. PMID- 29464566 TI - Conformational Equilibrium of Human Platelet Integrin Investigated by Three Dimensional Electron Cryo-Microscopy. AB - Integrins are bidirectional transmembrane receptors that play central roles in hemostasis and arterial thrombosis. They have been subject to structural studies for many years, in particular using X-ray crystallography, nuclear magnetic resonance spectroscopy, and two-dimensional negative stain electron microscopy. Despite considerable progress, a full consensus on the molecular mechanism of integrin activation is still lacking. Three-dimensional reconstructions of full length human platelet integrin alphaIIbbeta3 in lipid-bilayer nanodiscs obtained by electron cryo-microscopy and single-particle reconstruction have shed new light on the activation process. These studies show that integrin alphaIIbbeta3 exists in a continuous conformational equilibrium ranging from a compact nodular conformation similar to that obtained in crystal structures to a fully extended state with the leg domains separated. This equilibrium is shifted towards the extended conformation when extracellular ligands, cytosolic activators and lipid bilayer nanodiscs are added. Addition of cytosolic activators and extracellular ligands in the absense of nanodiscs produces significantly less dramatic shifts, emphasizing the importance of the membrane bilayer in the activation process. PMID- 29464567 TI - Mitochondrial Proteolipid Complexes of Creatine Kinase. AB - Isoforms of creatine kinase (CK) generate and use phosphocreatine, a concentrated and highly diffusible cellular "high energy" intermediate, for the main purpose of energy buffering and transfer in order to maintain cellular energy homeostasis. The mitochondrial CK isoform (mtCK) localizes to the mitochondrial intermembrane and cristae space, where it assembles into peripherally membrane bound, large cuboidal homooctamers. These are part of proteolipid complexes wherein mtCK directly interacts with cardiolipin and other anionic phospholipids, as well as with the VDAC channel in the outer membrane. This leads to a stabilization and cross-linking of inner and outer mitochondrial membrane, forming so-called contact sites. Also the adenine nucleotide translocator of the inner membrane can be recruited into these proteolipid complexes, probably mediated by cardiolipin. The complexes have functions mainly in energy transfer to the cytosol and stimulation of oxidative phosphorylation, but also in restraining formation of reactive oxygen species and apoptosis. In vitro evidence indicates a putative role of mtCK in mitochondrial phospholipid distribution, and most recently a role in thermogenesis has been proposed. This review summarizes the essential structural and functional data of these mtCK complexes and describes in more detail the more recent advances in phospholipid interaction, thermogenesis, cancer and evolution of mtCK. PMID- 29464565 TI - Ryanodine Receptor Structure and Function in Health and Disease. AB - Ryanodine receptors (RyRs) are ubiquitous intracellular calcium (Ca2+) release channels required for the function of many organs including heart and skeletal muscle, synaptic transmission in the brain, pancreatic beta cell function, and vascular tone. In disease, defective function of RyRs due either to stress (hyperadrenergic and/or oxidative overload) or genetic mutations can render the channels leaky to Ca2+ and promote defective disease-causing signals as observed in heat failure, muscular dystrophy, diabetes mellitus, and neurodegerative disease. RyRs are massive structures comprising the largest known ion channel bearing macromolecular complex and exceeding 3 million Daltons in molecular weight. RyRs mediate the rapid release of Ca2+ from the endoplasmic/sarcoplasmic reticulum (ER/SR) to stimulate cellular functions through Ca2+-dependent processes. Recent advances in single-particle cryogenic electron microscopy (cryo EM) have enabled the determination of atomic-level structures for RyR for the first time. These structures have illuminated the mechanisms by which these critical ion channels function and interact with regulatory ligands. In the present chapter we discuss the structure, functional elements, gating and activation mechanisms of RyRs in normal and disease states. PMID- 29464568 TI - The Vacuolar ATPase - A Nano-scale Motor That Drives Cell Biology. AB - The vacuolar H+-ATPase (V-ATPase) is a ~1 MDa membrane protein complex that couples the hydrolysis of cytosolic ATP to the transmembrane movement of protons. In essentially all eukaryotic cells, this acid pumping function plays critical roles in the acidification of endosomal/lysosomal compartments and hence in transport, recycling and degradative pathways. It is also important in acid extrusion across the plasma membrane of some cells, contributing to homeostatic control of cytoplasmic pH and maintenance of appropriate extracellular acidity. The complex, assembled from up to 30 individual polypeptides, operates as a molecular motor with rotary mechanics. Historically, structural inferences about the eukaryotic V-ATPase and its subunits have been made by comparison to the structures of bacterial homologues. However, more recently, we have developed a much better understanding of the complete structure of the eukaryotic complex, in particular through advances in cryo-electron microscopy. This chapter explores these recent developments, and examines what they now reveal about the catalytic mechanism of this essential proton pump and how its activity might be regulated in response to cellular signals.

AB - In the original publication, the abstract, conclusion was incorrectly published. PMID- 29464570 TI - Hepatic esterase activity is increased in hepatocyte-like cells derived from human embryonic stem cells using a 3D culture system. AB - OBJECTIVES: The aim of the study is to generate a spherical three-dimensional (3D) aggregate of hepatocyte-like cells (HLCs) differentiated from human embryonic stem cells and to investigate the effect of the 3D environment on hepatic maturation and drug metabolism. RESULTS: Quantitative real-time PCR analysis indicated that gene expression of mature hepatocyte markers, drug metabolizing enzymes, and hepatic transporters was significantly higher in HLCs cultured in the 3D system than in those cultured in a two-dimensional system (p < 0.001). Moreover, hepatocyte-specific functions, including albumin secretion and bile canaliculi formation, were increased in HLCs cultured in the 3D system. In particular, 3D spheroidal culture increased expression of CES1 and BCHE, which encode hepatic esterases (p < 0.001). The enhanced activities of these hepatic esterases were confirmed by the cholinesterase activity assay and the increased susceptibility of HLCs to oseltamivir, which is metabolized by CES1. CONCLUSIONS: 3D spheroidal culture enhances the maturation and drug metabolism of stem cell derived HLCs, and this may help to optimize hepatic differentiation protocols for hepatotoxicity testing. PMID- 29464571 TI - Direct electrospinning of poly(vinyl butyral) onto human dermal fibroblasts using a portable device. AB - OBJECTIVE: To demonstrate that uniform poly(vinyl butyral) (PVB) fibres can be safely electrospun onto a monolayer of human dermal fibroblasts using a portable device. RESULTS: PVB in solvent mixtures containing various amounts of ethanol and water was electrospun. Six percent (weight-to-volume ratio) PVB in a 9:1 ethanol:water ratio was the solution with the highest content in water that could be electrospun into consistent fibres with an average diameter of 0.9 MUm (+/- 0.1 MUm). Four and five percent PVB solutions created beaded fibres. A 8:2 ethanol:water solution lead to microbead formation while a 7:3 ethanol:water mix failed to fully dissolve. The selected solution was successfully electrospun onto a monolayer of human dermal fibroblasts and the process had no significant effect (p < 0.05) on cell viability compared to the control without fibres. CONCLUSIONS: PVB-ethanol-water solutions could be electrospun without damaging the exposed cell layer. However, further work is required to demonstrate the long-term effect of PVB as a wound healing material. PMID- 29464572 TI - Brain Renin-Angiotensin System Blockade Attenuates Methamphetamine-Induced Hyperlocomotion and Neurotoxicity. AB - Methamphetamine (METH) abuse has become a major public health concern worldwide without approved pharmacotherapies. The brain renin-angiotensin system (RAS) is involved in the regulation of neuronal function as well as neurological disorders. Angiotensin II (Ang II), which interacts with Ang II type 1 receptor (AT1-R) in the brain, plays an important role as a neuromodulator in dopaminergic transmission. However, the role of brain RAS in METH-induced behavior is largely unknown. Here, we revealed that repeated METH administration significantly upregulated the expression of AT1-R in the striatum of mice, but downregulated dopamine D3 receptor (D3R) expression. A specific AT1-R blocker telmisartan, which can penetrate the brain-blood barrier (BBB), or genetic deletion of AT1-R was sufficient to attenuate METH-triggered hyperlocomotion in mice. However, intraperitoneal injection of AT1-R blocker losartan, which cannot penetrate BBB, failed to attenuate METH-induced behavior. Moreover, intra-striatum re-expression of AT1 with lentiviral virus expressing AT1 reversed the weakened locomotor activity of AT1-/- mice treated with METH. Losartan alleviated METH-induced cytotoxicity in SH-SY5Y cells in vitro, which was accompanied by upregulated expressions of D3R and dopamine transporter. In addition, intraperitoneal injection of perindopril, which is a specific ACE inhibitor and can penetrate BBB, significantly attenuated METH-induced hyperlocomotor activity. Collectively, our results show that blockade of brain RAS attenuates METH-induced hyperlocomotion and neurotoxicity possibly through modulation of D3R expression. Our findings reveal a novel role of Ang II-AT1-R in METH-induced hyperlocomotion. PMID- 29464574 TI - Targeted Pituitary Adenylate Cyclase-Activating Peptide Therapies for Migraine. AB - Here, we review the role of pituitary adenylate cyclase-activating peptide-38 (PACAP38) in migraine pathophysiology and data implicating PAC1 receptor as a future drug target in migraine. Much remains to be fully elucidated about migraine pathophysiology, but recent attention has focused on signaling molecule PACAP38, a vasodilator able to induce migraine attacks in patients who experience migraine without aura. PACAP38, with marked and sustained effect, dilates extracerebral arteries but not the middle cerebral artery. The selective affinity of PACAP38 to the PAC1 receptor makes this receptor a highly interesting and potential novel target for migraine treatment. Efficacy of antagonism of this receptor should be investigated in randomized clinical trials. PMID- 29464573 TI - Intrinsic Inflammation Is a Potential Anti-Epileptogenic Target in the Organotypic Hippocampal Slice Model. AB - Understanding the mechanisms of epileptogenesis is essential to develop novel drugs that could prevent or modify the disease. Neuroinflammation has been proposed as a promising target for therapeutic interventions to inhibit the epileptogenic process that evolves from traumatic brain injury. However, it remains unclear whether cytokine-related pathways, particularly TNFalpha signaling, have a critical role in the development of epilepsy. In this study, we investigated the role of innate inflammation in an in vitro model of post traumatic epileptogenesis. We combined organotypic hippocampal slice cultures, representing an in vitro model of post-traumatic epilepsy, with multi-electrode array recordings to directly monitor the development of epileptiform activity and to examine the concomitant changes in cytokine release, cell death, and glial cell activation. We report that synchronized ictal- and interictal-like activities spontaneously evolve in this culture. Dynamic changes in the release of the pro-inflammatory cytokines IL-1beta, TNFalpha, and IL-6 were observed throughout the culture period (3 to 21 days in vitro) with persistent activation of microglia and astrocytes. We found that neutralizing TNFalpha with a polyclonal antibody significantly reduced ictal discharges, and this effect lasted for 1 week after antibody washout. Neither phenytoin nor an anti-IL-6 polyclonal antibody was efficacious in inhibiting the development of epileptiform activity. Our data show a sustained effect of the anti-TNFalpha antibody on the ictal progression in organotypic hippocampal slice cultures supporting the critical role of inflammatory mediators in epilepsy and establishing a proof-of principle evidence for the utility of this preparation to test the therapeutic effects of anti-inflammatory treatments.

AB - The culture supernatant of Clostridium botulinum type C, concentrated by addition of RNA, acid precipitation and subsequent protamine treatment was used as starting material for rapid purification of L toxin (mol. wt. ca. 500K) and M toxin (mol. wt. ca. 350K) of C1 neurotoxin by ion-exchange chromatography on a Mono S column by fast performance liquid chromatography (FPLC). L and M toxins were highly purified further by gel permeation chromatography through a TSK G3000SW column at pH 6.0 by high performance liquid chromatography (HPLC). Purified S toxin (mol. wt. ca. 150K, Cl neurotoxin without a nontoxic component) was then obtained from L toxin rapidly by gel permeation chromatography at pH 7.3 through a TSK G3000SW column by HPLC. Purified S toxin was also obtained rapidly from M and L toxins by ion-exchange chromatography on a Mono Q column at pH 8.0 using an FPLC system. The purified preparations of L, M and S toxins gave single bands on conventional polyacrylamide gel electrophoresis, and had specific activities of 2.8, 6.7, and 14-21 * 107 LD50/mg N, respectively, in mice. On immunoelectrophoresis, purified S toxin gave a single arc against anti-crude toxin serum. The yield of toxicity as L and M toxins was 73.1% (32.5% as L toxin and 40.6% as M toxin) from the protamine-treated concentrated culture supernatant. The recovery of toxicity as S toxin from purified L or M toxin was almost 100% (97.6-100% of L toxin and 97.5% of M toxin). These procedures provide a rapid method for purifying L and M toxins, which have stable toxicities. The method will also be very useful for rapid preparation of the toxic component (S toxin) of C1 neurotoxin, which is unstable, in small amounts from the L and M toxins just before its use in experiments. PMID- 29464577 TI - Behavioral consequences of children with sleep-disordered breathing after adenotonsillectomy. AB - BACKGROUND: Adenotonsillectomy (AT) has been an effective treatment for sleep disordered breathing (SDB) in children, and several studies described the risk of postoperative weight gain and obesity in children treated with AT. The present study aimed to evaluate behavioral improvements in children with SDB one year after adenotonsillectomy and to investigate an influence of postoperative weight gain on behaviors. METHODS: The study included 170 children aged 5-11 years who underwent adenotonsillectomy for SDB and 150 controls. Body mass index percentile was obtained for age and gender, and parental sleep-related breathing disorder (SRBD) questionnaire was used to assess the severity of SDB. Psychological assessment was performed pre- and post-adenotonsillectomy using standardized questionnaires including strength and difficulties questionnaire, children's depression inventory and screen for child anxiety-related emotional disorder. RESULTS: The mean age of 170 patients was 7.7 +/- 1.5 years with 73 (42.9%) girls and 97 (57.1%) boys. The mean follow-up period were 15.4 +/- 2.7 months. The patients had shown significant improvements in SDB scores as well as in questionnaire-based behavioral problems after adenotonsillectomy. The odds of a child being overweight were significantly increased after adenotonsillectomy. Less improvements in hyperactivity and conduct problems were observed in the patients with older ages, higher SRBD scores, and overweight/obesity at 1-year follow-up after adenotonsillectomy. CONCLUSION: These data suggest that abnormal behavioral outcomes should be evaluated postoperatively, which potentially could be reduced with the early adenotonsillectomy and adequate postoperative weight control. PMID- 29464578 TI - Incidence and risk factors of post-phototherapy neonatal rebound hyperbilirubinemia. AB - BACKGROUND: To determine the incidence and risk factors of post-phototherapy rebound hyperbilirubinemia because data about bilirubin rebound in neonates are lacking and few studies have concerned this condition. METHODS: A prospective observational study was conducted on 500 neonates with indirect hyperbilirubinemia who were treated according to standard guidelines. Total serum bilirubin (TSB) was measured at 24-36 h after phototherapy; significant bilirubin rebound (SBR) is considered as increasing TSB that needs reinstitution of phototherapy. RESULTS: A total of 124 (24.9%) neonates developed SBR with TSB increased by 3.4 (2.4-11.2) mg/dL after stopping phototherapy. Multiple logistic regression model revealed the following significant risk factors for rebound: low birth weight (B = 1.3, P < 0.001, OR 3.5), suspected sepsis (B = 2.5, P < 0.001, OR 12.6), exposure to intensive phototherapy (B = 0.83, P = 0.03, OR 2.3), hemolysis (B = 1.2, P < 0.001, OR 3.1), high discharge bilirubin level (B = 0.3, P = 0.001, OR 1.3), and short duration of conventional phototherapy (B = - 1.2, P < 0.001, OR 0.3). CONCLUSIONS: SBR should be considered in neonates with hemolysis, low birth weight, suspected sepsis, short duration of conventional phototherapy, exposure to intensive phototherapy, and relatively high discharge TSB. These risk factors should be taken into account when planning post-phototherapy follow-up. PMID- 29464579 TI - Oxcarbazepine oral suspension in young pediatric patients with partial seizures and/or generalized tonic-clonic seizures in routine clinical practice in China: a prospective observational study. AB - BACKGROUND: This study aimed to assess efficacy and safety of oxcarbazepine (OXC) oral suspension in pediatric patients aged 2-5 years with partial seizures (PS) and/or generalized tonic-clonic seizures (GTCS) in real-world clinical practice in China. METHODS: This 26-week, prospective, single-arm, multicenter, observational study recruited pediatric patients aged 2-5 years with PS or GTCS suitable for OXC oral suspension treatment based on physicians' judgments from 11 medical centers in China. Enrolled subjects started OXC oral suspension treatment as monotherapy or in combination with other antiepileptic drugs. Primary efficacy outcome was the percentage of pediatric subjects achieving >= 50% seizure frequency reduction at the end of the 26-week treatment. Secondary efficacy related parameters and safety parameters such as adverse events (AEs) and serious AEs (SAEs) were also monitored during the 26-week treatment period. RESULTS: Six hundred and six pediatric patients were enrolled and 531 (87.6%) completed the study. After 26 weeks of treatment, 93.3% subjects achieved >= 50% seizure frequency reduction, and 81.8% achieved 100% seizure frequency reduction compared to baseline. Among different seizure types, OXC was effective in all subjects with simple PS and in > 90% of subject with other type of seizure present in the study. AEs were observed in 49 (8.1%) subjects. Only three subjects experienced SAE. Rash (n = 18, 2.97%) was the most common AE. Only 17 subjects discontinued due to AEs. CONCLUSION: This study, reporting the real-world data, further confirms the efficacy and good safety profile of OXC oral suspension in Chinese pediatric patients aged 2-5 years with PS and/or GTCS. PMID- 29464580 TI - Outcome after early mobilization following hip reconstruction in children with developmental hip dysplasia and luxation. AB - BACKGROUND: Most orthopedic surgeons prefer spica cast immobilization in children for 4 to 12 weeks after surgical hip reconstruction in children with developmental hip dysplasia. This challenging treatment may be associated with complications. Studies are lacking that focus on early mobilization without casting for postoperative care after hip reconstruction. METHODS: Twenty-seven children (3.4+/-2.0 years), including 33 hips with developmental hip dysplasia (DDH) and dislocation of the hip (Tonnis grade 1 to 4), who underwent hip reconstruction (Dega acetabuloplasty, varisation-derotation osteotomy and facultative open reduction) were retrospectively included in this study. Postoperatively the patients were placed in an individual foam shell with 30 degrees of hip abduction, hip extension, and neutral rotation. Early mobilization physiotherapy was performed within the first few days after the surgery under epidural anaesthesia. Full weight bearing was allowed after 3-4 weeks. All children received a clinical examination and radiographic evaluation before and after surgical intervention. The follow-up period was 12.3+/-2.9 months. RESULTS: On average, the postoperative acetabular index decreased significantly from 36.9 to 21.7 degrees and the center-edge angle increased from 9.9 to 28.6 degrees. All hips had reached Tonnis grade 1 at the time of the last follow-up. No complications such as dislocation of the bone wedge, avascular necrosis of the acetabulum or femur, lack of non-union, or nerve injury, were reported. CONCLUSIONS: In this cohort study, hip reconstruction was successful according to clinical and radiographic outcome parameters after early mobilization without cast therapy. Early mobilization may be used as an alternative treatment option after hip reconstruction in DDH. PMID- 29464581 TI - Urinary neutrophil gelatinase-associated lipocalin (NGAL) and serum cystatin C measurements for early diagnosis of acute kidney injury in children admitted to PICU. AB - BACKGROUND: Acute kidney injury (AKI) is common in critically ill children with significant mortality and morbidity. Serum creatinine is an insensitive and late biomarker compared to newly proposed AKI biomarkers. METHODS: Prospective study in pediatric intensive care unit (PICU) over three months to compare between serum cystatin-C (s-Cys-C) and urinary neutrophil gelatinase-associated lipocalin (uNGAL) as AKI biomarkers at multiple time points with pediatric risk, injury, failure, loss, end-stage renal disease (pRIFLE) classification in diagnosing AKI. RESULTS: Forty children were recruited. Of these 40 children, 22 developed AKI according to pRIFLE criteria. There was no significant difference between AKI and non-AKI in age (P = 0.29). Post cardiac surgery, renal insult was the main cause of AKI (27.3%). There was a twofold increased risk of incident AKI in those patients with high baseline uNGAL at PICU admission and almost a fourfold increased risk in patients with high baseline s-Cys-C at PICU admission. uNGAL levels were highly predictive of AKI during the follow-up period [area under the curve (AUC) = 0.76, 95% confidence interval (CI) 0.61-0.92]. The cutoff point with the highest correctly classified proportion was 223 ng/mL (>= 12 centiles) which correctly predict 80.0% patients with AKI, with a corresponding sensitivity of 72.7% and a specificity of 89.9%. AUC for s-Cys-C was 0.86 (95% CI 0.75-0.97), and the highest correctly classified proportion was 1009 ug/L (>= 13 centiles); 75% of patients with AKI, with a corresponding sensitivity of 63.6% and a specificity of 88.9%. CONCLUSION: uNGAL and s-Cys-C predicts AKI early in critically ill children. PMID- 29464582 TI - Rebamipide in Functional and Organic Dyspepsia: Sometimes the Best Offense Is a Good Defense.

PMID- 29464583 TI - Intestinal Involvement in Systemic Sclerosis: A Clinical Review. AB - Systemic sclerosis (SSc) is a chronic systemic disease characterized by microvasculopathy, autoantibodies, and extensive fibrosis. Intestinal involvement is frequent in SSc and represents a significant cause of morbidity. The pathogenesis of intestinal involvement includes vascular damage, nerve dysfunction, smooth muscle atrophy, and fibrosis, causing hypomotility, which leads to small intestinal bacterial overgrowth (SIBO), malabsorption, malnutrition, diarrhea, pseudo-obstruction, constipation, pneumatosis intestinalis, and fecal incontinence. Manifestations are often troublesome and reduce quality of life and life expectancy. Assessment of intestinal involvement includes screening for small intestine hypomotility, malnutrition, SIBO, and anorectal dysfunction. Current management of intestinal manifestations is largely inadequate. Patients with diarrhea are managed with low-fat diet, medium-chain triglycerides, avoidance of lactulose and fructose, and control of bacterial overgrowth with antibiotics for SIBO. In diarrhea/malabsorption, bile acid sequestrant and pancreatic enzyme supplementation may help, and nutritional support is needed. General measures are applied for constipation, and intestine rest plus antibiotics for pseudo-obstruction. Fecal incontinence is managed with measures for associated SIBO, or constipation, and with behavioral therapies. Pneumatosis intestinalis is usually an incidental finding that does not require any specific treatment. Immunomoduation should be considered early in intestinal involvement. Multidisciplinary approach of intestinal manifestations in SSc by gastroenterologists and rheumatologists is required for optimum management.

AB - BACKGROUND: The necessity of histological analysis is increasing. A 19-gauge histology needle (PC19) in endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) has recently been developed and has shown high yields of tissue acquisition and histological diagnosis. AIMS: To compare the histological diagnostic yield in single-pass EUS-FNA for solid lesions using PC19 and a standard 19-gauge needle (EC19). PATIENTS AND METHODS: Consecutive patients with solid lesions were enrolled and underwent one pass with each of PC19 and EC19 for EUS-FNA with the randomized order of the needles. The primary endpoint was the histological diagnostic accuracy. The secondary endpoints were the feasibility, yield of histological core, cytological and overall diagnostic accuracies, and adverse events. Subgroup analysis was performed for the optimal situation with PC19. RESULTS: Of the 115 patients, 110 underwent EUS-FNA and five were excluded. EUS-FNA was performed from the esophagus in four, stomach in 80, or duodenum in 26. The final diagnosis was malignancy in 100 and benign in 10. The feasibility was 98.2 and 97.3% with PC19 and EC19, respectively (p = 1.00). The rate of presence of a histological core and the histological, cytological, and overall diagnostic accuracies for PC19 versus EC19 were 84.6 versus 80.9% (p = 0.593), 83.6 versus 73.6% (p = 0.099), 63.6 versus 56.4% (p = 0.335), and 90.0 versus 79.1% (p = 0.039), respectively. PC19 was favored in the trans-esophageal/gastric approaches to obtain a histological diagnosis (p = 0.013). Adverse events were observed in four patients. CONCLUSION: Single-pass EUS-FNA with PC19 was feasible and showed significantly higher overall diagnostic accuracy and an increased tendency towards histological diagnostic accuracy, especially with trans esophageal/gastric FNA.

In this letter, we highlighted the role of functional meningeal lymphatics and cerebrospinal fluid outflow. PMID- 29464587 TI - Comparison of the Effects of Vonoprazan and Lansoprazole for Treating Endoscopic Submucosal Dissection-Induced Artificial Ulcers. AB - BACKGROUND: Vonoprazan exhibits a more potent, rapid, and longer-lasting inhibitory effect on gastric acid secretion than proton pump inhibitors; however, whether it is more effective than PPI for treating endoscopic submucosal dissection (ESD)-induced artificial ulcers remains controversial. AIM: This study aimed to assess and compare the effects of vonoprazan and lansoprazole for treating ESD-induced artificial ulcers. METHODS: This prospective, randomized controlled trial enrolled 149 patients who underwent ESD for the treatment of early gastric neoplasms from April 2015 to May 2017. They were randomly treated with either 20 mg/day vonoprazan (V group) or 30 mg/day lansoprazole (L group) orally. The primary end points were the area and shrinkage ratio of the ulcers at 4 and 8 weeks post-ESD. RESULTS: Data from 127 patients were analyzed, which showed that the 4- and 8-week healing ratios were not significantly different between the V and L groups (4 weeks, 16.3 vs. 25.8%; 8 weeks, 86.9 vs. 90.9%, respectively). Similarly, the shrinkage ratio, categorized as less than 90%, 90% or more but less than 100%, or 100% at 4 weeks and as less than 100% or 100% at 8 weeks were not statistically different between the V and L groups (4 weeks: 12, 41, 8 vs. 13, 41, 12, p = 0.7246; 8 weeks: 9, 52 vs. 9, 57, p = 0.8568). Delayed bleeding was also not significantly different between both the groups (5.4 vs. 5.3%; p = 0.9844). CONCLUSIONS: Vonoprazan is as effective as lansoprazole in treating ESD-induced ulcers.

AB - The present work aimed to investigate the presence of T. vivax DNA in the semen of experimentally infected goats. Twelve male goats native to the Brazilian Northeast, adults, were randomly assigned to two experimental groups: the infected group consisting of six goats infected intravenously with 0.5 mL of blood containing approximately 1.25 * 105 trypomastigotes of T. vivax, and a control group composed of six uninfected goats. After the infection, clinical examinations aiming to evaluate rectal temperature, parasitemia and hematocrit were performed. Semen samples were collected from goats by electroejaculation on the 7th, 14th and 21st days post-infection (dpi). The recombinant DNA-encoding gene encoding the L-like-specific gene for T. vivax. The infection was characterized by increased rectal temperature, high parasitemia and significant reduction of hematocrit values. Results for T. vivax DNA detection using TviCatL PCR were positive in all semen samples from the infected group collected on 7th, 14th and 21st dpi. The presence of T. vivax DNA in 7th dpi suggests the early invasion of the parasite in the reproductive organs. Also, the finding of T. vivax DNA in all periods analyzed may suggest the continued elimination of the parasite in the semen, which may increase the chances of sexual transmission. Thus, T. vivax DNA is recorded for the first time in the semen of infected goats. Thus, these data are of great importance, since the detection of the T. vivax genetic material in the semen may point to the possibility that the parasite may be transmitted through the sexual pathway. PMID- 29464590 TI - Methods for the effective study of collective behavior in a radial arm maze. AB - Collective behaviors are observed throughout nature, from bacterial colonies to human societies. Important theoretical breakthroughs have recently been made in understanding why animals produce group behaviors and how they coordinate their activities, build collective structures, and make decisions. However, standardized experimental methods to test these findings have been lacking. Notably, easily and unambiguously determining the membership of a group and the responses of an individual within that group is still a challenge. The radial arm maze is presented here as a new standardized method to investigate collective exploration and decision-making in animal groups. This paradigm gives individuals within animal groups the opportunity to make choices among a set of discrete alternatives, and these choices can easily be tracked over long periods of time. We demonstrate the usefulness of this paradigm by performing a set of refuge-site selection experiments with groups of fish. Using an open-source, robust custom image-processing algorithm, we automatically counted the number of animals in each arm of the maze to identify the majority choice. We also propose a new index to quantify the degree of group cohesion in this context. The radial arm maze paradigm provides an easy way to categorize and quantify the choices made by animals. It makes it possible to readily apply the traditional uses of the radial arm maze with single animals to the study of animal groups. Moreover, it opens up the possibility of studying questions specifically related to collective behaviors. PMID- 29464591 TI - Design and Characterization of Topical Formulations: Correlations Between Instrumental and Sensorial Measurements. AB - The interaction between cosmetic emulsions and the skin's surface is an important factor to consider in the development of topical formulations. Two important ingredients in cosmetic formulations are waxes and polymers. The physical and mechanical properties of formulations directly impact the interface skin formulation. To evaluate this interaction, it is important to study the rheology, texture, and sensory properties. In this context, the aim of the study was to evaluate the influence of waxes and polymers on the rheological behavior, texture profile, and sensorial properties of topical formulations and the correlation between these parameters. The best combination of a wax and a polymer was determined by full factorial design of experiments and applied to develop eight formulations that were tested in relation to rheological, mechanical, and sensorial properties. The polymer helps with the spreadability of the formulation, and the wax had a strong influence on the parameters related to the structure of emulsions. A correlation between these parameters was observed. This way, it was possible to compare theoretical and practical data, except between the flow index and the work of shear. Finally, it was possible to predict sensorial aspects from rheological and texture parameters, making the formulation process easier and more integrated with all stages of the development of new topical formulations. Thus, the present study introduces a new proposal in the development of cosmetics. PMID- 29464593 TI - Improving Properties of Albendazole Desmotropes by Supramolecular Systems with Maltodextrin and Glutamic Acid. AB - Albendazole, an effective broad-spectrum anthelmintic agent, showed unpredictable therapeutic response caused by poor water solubility and slow dissolution rate. Then, novel binary and multicomponent supramolecular systems of two different solid forms of albendazole (I and II) with maltodextrin alone or with glutamic acid were studied as an alternative to improve the oral bioavailability of albendazole. The interactions and effects on the properties of albendazole were studied in solution and solid state. The solid systems were characterized using Raman and Fourier transform-infrared spectroscopy, thermal analysis, powder X-ray diffraction, and scanning electron microscopy. The solubility measurements, performed in aqueous and simulated gastric fluid, showed that albendazole (form II) was the most soluble form, while its supramolecular systems showed the highest solubility in simulated gastric fluid. On the other hand, the dissolution profiles of binary and multicomponent systems in simulated gastric fluid displayed pronounced increments of the dissolved drug and a faster dissolution rate compared to those of free albendazole forms. Thus, these supramolecular structures constitute an interesting alternative to improve the physicochemical properties of albendazole, with potential application for the preparation of pharmaceutical oral formulations. PMID- 29464592 TI - Delivery Considerations of Highly Viscous Polymeric Fluids Mimicking Concentrated Biopharmaceuticals: Assessment of Injectability via Measurement of Total Work Done "WT". AB - An account is given of the recent development of the highly viscous complex biopharmaceuticals in relation to syringeability and injectability. The specific objective of this study is to establish a convenient method to examine problem of the injectability for the needle-syringe-formulation system when complex formulations with diverse viscosities are used. This work presents the inter relationship between needle size, syringe volume, viscosity, and injectability of polymeric solutions having typical viscosities encountered in concentrated biologics, by applying a constant probe crosshead speed on the plunger-syringe needle assembly and continuously recording the force-distance profiles. A computerized texture analyzer was used to accurately capture, display, and store force, displacement, and time data. The force-distance curve and area under the curve are determined, and total work done for complete extrusion of the syringe content was calculated automatically by applying an established Matlab program. Various concentrations (i.e., 0.5-4% w/v of polymeric fluids/dispersions) of polyethylene oxide (PEO) and hydroxypropyl methylcellulose (HPMC) with viscosity ranges of 5-100 cP mimicking concentrated monoclonal antibody solutions and complex biopharmaceutical formulations are investigated. Results indicate that calculated values of total work done to completely extrude the syringe content are the most appropriate parameter that describes viscosity-injection force of dispersed formulations. Additionally, the rheological properties of HPMC and PEO fluids in the context of syringeability and injectability are discussed. PMID- 29464594 TI - Inhalable Levofloxacin Liposomes Complemented with Lysozyme for Treatment of Pulmonary Infection in Rats: Effective Antimicrobial and Antibiofilm Strategy. AB - Treatment of bacterial infections becomes increasingly complicated due to increasing bacterial resistance and difficulty in developing new antimicrobial agents. Emphasis should be laid on improvising the existing treatment modalities. We studied the improved antimicrobial and antibiofilm activity of levofloxacin (LFX) and lysozyme (LYS) in microbiological studies. LFX at sub-minimum inhibitory concentration with LYS eradicated > 85% of preformed biofilm. LFX was actively loaded into the liposomes using pH gradient method and was spray-dried with LYS solution. Percent entrapment of LFX in liposome was > 80% and prolonged cumulative release of 85% LFX at the end of 12 h. In vitro lung deposition study and solid-state characterization for spray dried LFX liposome in combination with LYS (LFX liposome-LYS) was performed. Co-spray dried product had mass median aerodynamic diameter ranging < 5 MUm. In pharmacodynamic study, Staphylococcus aureus infected rats were treated with LFX liposome-LYS. Lungs, bronchoalveolar lavage fluid (BALF), and nasal fluid were evaluated for microbial burden. Expression of cytokine levels in BALF and serum were also studied by ELISA. In addition, mRNA expression for lung inflammatory mediators and lung myeloperoxidase activity were carried out. Further, lungs and histological changes were observed grossly. Untreated infected rat lungs demonstrated higher mRNA expression for inflammatory markers, cytokine levels, and microbial load compared to vehicle control. Conversely, LFX liposome-LYS significantly abated these adverse repercussions. Histology findings were also in agreement of above. Acute toxicity study revealed safeness of LFX liposome-LYS. Our findings confirm LFX liposome-LYS exhibited prolonged, improved antibiofilm and antimicrobial efficacy in treating S. aureus infection. PMID- 29464595 TI - Toxicological study of the degradation products of antineoplastic agent etoposide in commercial formulation treated by heterogeneous photocatalysis using SrSnO3. AB - Etoposide is an antineoplastic agent used for treating lung cancer, testicular cancer, breast cancer, pediatric cancers, and lymphomas. It is a pollutant due to its mutagenic and carcinogenic potential. Disposal of waste from this drug is still insufficiently safe, and there is no appropriate waste treatment. Therefore, it is important to use advanced oxidative processes (AOPs) for the treatment and disposal of medicines like this. The use of strontium stannate (SrSnO3) as a catalyst in heterogeneous photocatalysis reactions has emerged as an alternative for the removal of organic pollutants. In our study, SrSnO3 was synthesized by the combustion method and characterized by X-ray diffraction (XRD), Raman, UV-Vis, and scanning electron microscopy (SEM) techniques, obtaining a surface area of 3.28 m2 g-1 with cubic and well-organized crystallinity and a band gap of 4.06 eV. The experimental conditions optimized for degradation of an etoposide solution (0.4 mg L-1) were pH 5 and catalyst concentration of 1 g L-1. The results showed that the degradation processes using SrSnO3 combined with H2O2 (0.338 mol L-1) obtained total organic carbon removal from the etoposide solution, 97.98% (+/- 4.03 * 10-3), compared with TiO2, which obtained a mineralization rate of 72.41% (+/- 6.95 * 10-3). After photodegradation, the degraded solution showed no toxicity to zebrafish embryos through embryotoxicity test (OECD, 236), and no genotoxicity using comet assay and micronucleus test. PMID- 29464596 TI - Adsorptive removal of organics from aqueous phase by acid-activated coal fly ash: preparation, adsorption, and Fenton regenerative valorization of "spent" adsorbent. AB - Raw coal fly ash was activated to an adsorbent by sulfuric acid impregnation. The activation condition, the adsorption capacity, and the regenerative valorization of the adsorbent were studied. The results show that the optimal preparation conditions of the adsorbent are [H2SO4] = 1 mol L-1, activation time = 30 min, the ratio of coal fly ash to acid = 1:20 (g:mL), calcination temperature = 100 degrees C. The adsorption of p-nitrophenol on the adsorbent accords with the pseudo-second-order kinetic equation and the adsorption rate constant is 0.089 g mg-1 min-1. The adsorption on this adsorbent can be considered enough after 35 min, when the corresponding adsorption capacity is 1.07 mg g-1 (85.6% of p nitrophenol removal). Compared with raw coal fly ash, the adsorbent has a stable adsorption performance at low pH range (pH = 1-6) and the adsorption of p nitrophenol is an exothermic process. Ninety minutes is required for the regenerative valorization of saturated adsorbent by Fenton process. The regenerative valorization for this saturated adsorbent can reach 89% under the optimal proposed conditions (30 degrees C, pH = 3, [H2O2] = 5.0 mmol L-1, [Fe2+] = 5.5 mmol L-1). Within 15 experimental runs, the adsorbent has a better and better stability with the increase of experimental runs. Finally, the mechanism of activating coal fly ash is proposed, being verified by the results of the SEM and BET test. PMID- 29464597 TI - The environmental Kuznets curve in the presence of corruption in developing countries. AB - Environmental degradation is at an alarming level in developing economies. The present paper examines the direct and indirect impacts of corruption on environmental deterioration using the panel data of 64 developing countries. Adopting the generalized method of moments (GMM) technique, the paper finds evidence that corruption exhibits a positive impact on pollution. Subsequently, there is also evidence indicating that the level of pollution tends to be higher in countries with a higher level of corruption, eliminating the effectiveness of income effect on environmental preservation. These results also suggest that environmental degradation is monotonically increasing with higher corruption and invalidate the presence of the EKC. Hence, a policy focuses that an anti corruption particularly in the environmental and natural resources sector needs to be emphasized and enforced in order to reduce or possibly to totally eliminate the rent for corruption. PMID- 29464598 TI - Ultrasound enhanced activation of peroxydisulfate by activated carbon fiber for decolorization of azo dye. AB - Activated carbon fiber (ACF) has become an emerging activator for peroxydisulfate (PDS) to generate sulfate radical (SO4*-). However, the relative low activation efficiency and poor contaminant mineralization limited its widespread application. Herein, ultrasound (US) was introduced to the ACF activated PDS system, and the synergistic effect of US and ACF in PDS activation and the enhancement of contaminant mineralization were investigated. The synergistic effect of US and ACF was observed in the PDS activation to decolorize orange G (OG). The decolorization efficiency increased with increasing ACF loading and US power, and PDS/OG ratio from 1 to 40. The activation energy was determined to be 24.065 kJ/mol. The radical-induced decolorization of OG took place on the surface of ACF, and both SO4*- and hydroxyl radical (*OH) contributed to OG decolorization. The azo bond and naphthalene ring on OG were destructed to other aromatic intermediates and finally mineralized to CO2 and H2O. The introduction of US in the ACF/PDS system significantly enhanced the mineralization of OG. The combination of US and PDS was highly efficient to activate PDS to decolorize azo dyes. Moreover, the introduction of US remarkably improved the contaminant mineralization.

AB - To better monitor and remediate environments contaminated by cadmium (Cd), plants are used as hyperaccumulators or biomonitors; however, few have been identified for aquatic Cd pollution. In our study, two aquatic ornamental plants, Microsorum pteropus (Blume) Copel. and Echinodorus grisebachii Small, were studied for their Cd accumulation capacity, morphological characteristics, and leaf physiological indexes. Microsorum pteropus (Blume) Copel. leaf has the potential to hyperaccumulate Cd (166 mg/kg dry weight for 1 mg/L exposure), with no significant physiological difference under exposure. Echinodorus grisebachii Small had sensitive diagnostic responses to Cd toxicity, such as significant decreases in Chl (a + b) and Chl-a/b, increased peroxidase (POD) activity, greater malondialdehyde (MDA) content, and increased soluble sugar content. These results suggest that Microsorum pteropus (Blume) Copel. could have the potential to be a Cd hyperaccumulator, while Echinodorus grisebachii Small could serve as a biomonitor for Cd-contaminated water bodies. PMID- 29464600 TI - Comparative study of calcium alginate, ball-milled biochar, and their composites on aqueous methylene blue adsorption. AB - In this work, a novel composite, ball-milled biochar (BMB) encapsulated in calcium-alginate (CA) beads (CA-BMB), was synthesized as an alternative adsorbent for the removal of methylene blue (MB) from an aqueous solution. Sorption performance was compared among CA, BMB, and CA-BMB composite with batch adsorption experiments. With 25% BMB and 75% alginate, the new composite resembled CA in MB adsorption. With an initial MB concentration of 50 mg L-1, kinetics studies showed that 74% MB removal by CA-BMB was achieved within 8 h, followed by slow kinetics reaching 91% removal in 16 h. The adsorption kinetics was well explained by the Ritchie's kinetic model, indicative of energetically heterogeneous solid surface of the composite. Adsorption isotherms of BMB, CA, and CA-BMB can all be fitted with the Langmuir models; the adsorption capacity of CA-BMB (1210.7 mg g-1) was close to that of CA (1282.2 mg g-1) and much higher than that of BMB alone (184.1 mg g-1). The outstanding adsorption performance suggested that CA-BMB can serve as a low-cost and eco-friendly adsorbent for MB removal from an aqueous solution. PMID- 29464601 TI - Using a multi-method approach based on soil radon deficit, resistivity, and induced polarization measurements to monitor non-aqueous phase liquid contamination in two study areas in Italy and India. AB - Geochemical and geophysical surveys employing radon deficit, resistivity, and induced polarization (IP) measurements were undertaken on soil contaminated with non-aqueous phase liquids (NAPLs) in two different sites in India and in Italy. Radon deficit, validated through the comparison with average soil radon in reference unpolluted areas, shows the extension of contamination in the upper part of the unsaturated aquifers. In site 1 (Italy), the spill is not recent. A residual film of kerosene covers soil grains, inhibiting their chargeability and reducing electrical resistivity difference with background unpolluted areas. No correlation between the two parameters is observed. Soil volatile organic compounds (VOCs) concentration is not linked with radon deficit, supporting the old age of the spillage. NAPL pollution in sites 2a and 2b (India) is more recent and probably still active, as demonstrated by higher values of electrical resistivity. A good correlation with IP values suggests that NAPL is still distributed as droplets or as a continuous phase in the pores, strengthening the scenario of a fresh spill or leakage. Residual fraction of gasoline in the pore space of sites 2a and 2b is respectively 1.5 and 11.8 kg per cubic meter of terrain. This estimation is referred to the shallower portion of the unsaturated aquifer. Electrical resistivity is still very high indicating that the gasoline has not been strongly degraded yet. Temperature and soil water content influence differently radon deficit in the three areas, reducing soil radon concentration and partly masking the deficit in sites 2a and 2b.

AB - This study aims to reveal the effects of earthworms (Eisenia fetida) on bacterial profiles during the vermicomposting process of sewage sludge and cattle dung with the high-throughput sequencing technology. The earthworms could accelerate organic degradation and improve the stabilization process. Moreover, the addition of earthworms not only affected the bacterial numbers, but also increased the bacterial community diversity. The activity of earthworms had significant effects on the bacterial community structure as the bacterial community was clearly different between the vermicomposting and the control treatment. Furthermore, the earthworms affected the physical and chemical properties of substrates, thus promoting the growth of some microorganisms, such as Flavobacteria, Acidbacteria, and Planctomycetes. Earthworms largely inhibited the growth of various human pathogenic bacteria. In summary, earthworms significantly affected the bacterial community in vermicomposting and it could be applied as an authentically effective technique for the stabilization of organic wastes. PMID- 29464603 TI - Antioxidant biomarkers in Gammarus pulex to evaluate the efficiency of electrocoagulation process in landfill leachate treatment. AB - The discharge of landfill leachate into the environment without effective treatment poses a serious threat for the aquatic ecosystems. This present study was undertaken to evaluate whether electrocoagulation process is efficient for treatment landfill leachate (LL) or not by using antioxidant biomarkers in Gammarus pulex. Glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), and catalase (CAT) activities and malondialdehyde (MDA) and glutathione (GSH) levels in G. pulex exposed to untreated, treated, and diluted rates 1/10 and 1/20 in both LL during 24 and 96 h were tested. Physiochemical characteristics of leachate (chemical oxygen demand, electrical conductivity, pH, phosphate, turbidity, NH3, Cl-, and color) were determined pre and post treatment. All physiochemical characteristics of LL decreased after treatment process. GSH-Px and CAT activities and GSH and MDA levels were increased in untreated groups when compared to control (p < 0.05). After treatment by electrocoagulation, MDA and GSH levels and CAT activities were returned to control values. In conclusion, the abilities of LL to stimulate oxidative stress in G. pulex have been proven. The results revealed that antioxidant parameters are useful biomarkers for determining the treatment efficiency of the electrocoagulation process. PMID- 29464604 TI - Quantifying particulate matter accumulated on leaves by 17 species of urban trees in Beijing, China. AB - Airborne particulate matter (PM) has become a serious environmental problem and harms human health worldwide. Trees can effectively remove particles from the atmosphere and improve the air quality. In this study, a washing and weighing method was used to quantify accumulation of water-soluble ions and insoluble PM on the leaf surfaces and within the wax of the leaves for 17 urban plant species (including 4 shrubs and 13 trees). The deposited PM was determined in three size fractions: fine (0.2-2.5 MUm), coarse (2.5-10 MUm), and large (> 10 MUm). Significant differences in the accumulation of PM were detected among various species. The leaves of Platycladus orientalis and Pinus armandi were the most effective in capturing PM. Across the species, 65 and 35% of PM, on average, deposited on the leaf surface and in the wax, respectively. The greatest PM accumulation by mass on leaves was in the largest PM size fraction, while the accumulation of coarse and fine particle size fractions was smaller. Water soluble ions accumulated on the leaf surfaces contributed 28% to the total PM mass, on average. This study demonstrated that leaves of woody plants accumulate PM differently, and the most effective plant species should be selected in urban areas for attenuating ambient PM. PMID- 29464606 TI - Kinetics, isotherms, and thermodynamic studies of lead, chromium, and cadmium bio adsorption from aqueous solution onto Picea smithiana sawdust. AB - Lead (Pb), chromium (Cr), and cadmium (Cd) removal capacity of sawdust (Picea smithiana) from aqueous solution was investigated by conducting batch experiments. Thermodynamic parameters, like change in standard free energy (DeltaGTheta), enthalpy (DeltaHTheta) and entropy (DeltaSTheta) during bio adsorption process were estimated using the Van't Hoff equation. The maximum metals adsorption was observed at pH 8, 20 g L-1 bio-adsorbent and at 60 min of contact time. The metal adsorption kinetics was examined by fitting the pseudo first-order as well as four forms of pseudo-second-order kinetic models. Type 1 pseudo-second-order equation described adsorption kinetics better than others. Langmuir model and Freundlich equations were used for calculation of sorption parameters. The Langmuir maximum adsorption capacity of Pb, Cr, and Cd was 6.35, 3.37, and 2.87 mg g-1 at room temperature, respectively. The values of the separation factor (RL) were in between 0 and 1, indicating that bio-adsorption was favorable. Thermodynamics study revealed that the Pb, Cr, and Cd uptake reactions were endothermic and spontaneous. Results of the study asserted that the removal of heavy metal ions from aqueous solution is viable and the sawdust could be used in the treatment of effluents from industries, thereby reducing the level of water pollution. PMID- 29464605 TI - Polycyclic aromatic hydrocarbons (PAHs) in multi-phases from the drinking water source area of the Pearl River Delta (PRD) in South China: Distribution, source apportionment, and risk assessment. AB - Sixteen priority polycyclic aromatic hydrocarbons (PAHs) were investigated in the water dissolved phase (DP), suspended particulate matter (SPM), and sediment collected from the water source zone of the Pearl River Delta region. The sum of 16 PAH concentrations ranged from 92.8 to 324 ng/L in the water DP, from 28.8 to 205 ng/L in the SPM, and from 55.7 to 381 ng/g (d.w.) in the sediment. Compared with other areas globally, the PAH levels were considerably moderate in the DP and SPM and relatively low in the sediment. Spatial distribution of PAHs was site specific, and relatively higher PAH levels were found in the areas with dense population and heavy traffic. The PAH profile was dominated by two- and three ring PAHs, and PAH pollution was identified of pyrolytic origins. Based on risk quotient, the ecological risk in water was ranked as moderate, but the adverse health risk associated with water ingestion was minimal. Naphthalene and fluorene of the sediment samples showed potential biological impairment in some locations; nevertheless, the mean effects range median quotient suggested that the ecological risk of multiple PAHs was quite low (less than 10% incidence of adverse effects).

PMID- 29464607 TI - First report of an atypical new Aspergillus parasiticus isolates with nucleotide insertion in aflR gene resembling to A. sojae. AB - Aflatoxins are toxic and carcinogenic secondary metabolites produced primarily by the filamentous fungi Aspergillus flavus and Aspergillus parasiticus and cause toxin contamination in food chain worldwide. Aspergillus oryzae and Aspergillus sojae are highly valued as koji molds in the traditional preparation of fermented foods, such as miso, sake, and shoyu. Koji mold species are generally perceived of as being nontoxigenic and are generally recognized as safe (GRAS). Fungal isolates were collected from a California orchard and a few were initially identified to be A. sojae using beta-tubulin gene sequences blasted against NCBI data base. These new isolates all produced aflatoxins B1, B2, G1, and G2 and were named as Pistachio Winter Experiment (PWE) strains. Thus, it is very important to further characterize these strains for food safety purposes. The full length of aflR gene of these new isolates was sequenced. Comparison of aflR DNA sequences of PWE, A. parasiticus and A. sojae, showed that the aflatoxigenic PWE strains had the six base insertion (CTCATG) similar to domesticated A. sojae, but a pre termination codon TGA at nucleotide positions 1153-1155 was absent due to a nucleotide codon change from T to C. Colony morphology and scanning microscopic imaging of spore surfaces showed similarity of PWE strains to both A. parasiticus and A. sojae. Concordance analysis of multi locus DNA sequences indicated that PWE strains were closely linked between A. parasiticus and A. sojae. The finding documented the first report that such unique strains have been found in North America and in the world. PMID- 29464609 TI - ? PMID- 29464610 TI - ? PMID- 29464611 TI - ?

AB - Heart failure with preserved ejection fraction (HFpEF) has emerged as a public health burden with currently no effective medication. We assessed the treatment effects of the incretin hormone glucagon-like peptide-1 (GLP-1) on cardiac metabolism and function in a model of HFpEF. Following aortic banding, rats developed HFpEF characterized by diastolic dysfunction, pulmonary congestion, and poor survival (38%). A 4-week GLP-1 treatment via osmotic pumps significantly improved survival (70%) and reduced left ventricular stiffness, diastolic dysfunction, and pulmonary congestion. Isolated heart perfusion revealed preserved cardiac glucose oxidation (GO) and a shift in cardiac substrate utilization towards GO. While GLP-1 may boost insulin secretion and responsiveness, the protective effects were not related to cardiac insulin action. GLP-1 improves diastolic function and survival in rats with HFpEF, which was associated with a cardiac substrate switch towards GO. The therapeutic role of GLP-1 in HFpEF is new and warrants further investigation. PMID- 29464656 TI - Non-invasive Management Options for Erectile Dysfunction When a Phosphodiesterase Type 5 Inhibitor Fails. AB - Phosphodiesterase type 5 inhibitors (PDE5Is) are the drug of choice for medical management of erectile dysfunction (ED). On-demand PDE5Is have an overall efficacy of 60-70% for ED; 30-35% of patients fail to respond to a PDE5I, and 30 50% of non-responders can be salvaged with detailed counseling on proper use and physician follow-up to ensure that the patient has been prescribed an appropriate and full PDE5I clinical trial. True non-responders may be offered intracavernosal injections of erectogenic drugs, intraurethral alprostadil, or surgical insertion of a penile prosthesis. Such options are not discreet and are associated with more adverse effects than PDE5Is. Thus patients may request additional non invasive medical management options. This review describes published literature on patients who failed to respond to an on-demand PDE5I regimen and were treated with a non-invasive PDEI-based regimen, including switching from one PDE5I to another; increasing the dose of PDE5I above the labeled dosage range; using two PDE5Is concurrently; using a daily PDE5I regimen; or combining a PDE5I with a testosterone supplement, alpha-adrenergic antagonist, intraurethral or intracavernosal alprostadil, vacuum erection device, or low-intensity shock wave therapy. The limitations of published clinical trials do not allow for sufficient evidence to recommend one option over another. Therefore, in PDE5I-refractory patients, the choice of a specific next step should be individualized based on the preference of the patient and his sexual partner, the advantages and disadvantages of the various options, the concurrent medical illnesses and medications of the patient, and the patient's response to treatment. PMID- 29464657 TI - Acute obstructive suppurative pancreatic ductitis (AOSPD) in pancreatic cancer treated by nasopancreatic drainage. AB - An 80-year-old woman with pancreatic cancer was admitted with fever and abdominal pain. Blood examinations showed an elevated CRP level. On computed tomography (CT), a pancreatic tumor with a dilated upstream main pancreatic duct (MPD) was seen. Endoscopic retrograde cholangiopancreatography (ERCP) showed the strictured part of the MPD at the head of the pancreas with upstream dilatation. A nasopancreatic drainage tube was placed. Through the tube, purulent pancreatic juice was discharged and culture of the pancreatic juice grew Klebsiella pneumoniae. On the day after ERCP, the patient's condition and the laboratory results improved. The patient's disorder was diagnosed as acute obstructive suppurative pancreatitis with pancreatic cancer. PMID- 29464658 TI - Examining the Association Between Different Aspects of Socioeconomic Status, Race, and Disability in Hawaii. AB - Socioeconomic status and race/ethnicity are known to be associated with health disparities. This study used data (2010-2014) from the American Community Survey. Respondents over age 30 from Hawaii were included (n = 44,921). Outcome variables were self-reported disability in vision, hearing, ambulatory function, self-care, independent living, or cognitive function. Four measures of socioeconomic status were personal income, average income for the area, income inequality for area, and education. This study used multivariable logistic regression to predict disability by race/ethnicity and socioeconomic status, controlling for age and gender. All four measures of socioeconomic status were significant predictors of at least one type of disability after adjustment for age, gender, and other measures of socioeconomic status. Higher education was significantly related to having every type of disability. Similarly, people with high personal income were less likely to have each type of disability than those with middle income, and those with low income were more likely to have all disabilities except hearing. Income inequality was significantly associated with half the disabilities. Low area income was significantly associated with increased vision-related disability, while high income was associated with less likelihood of hearing related disability. Native Hawaiians were significantly more likely to report having a disability than Filipinos and Chinese for all six types of disability, Japanese for four, and whites for two, after adjustment. These results suggest that in order to reduce health disparities for Native Hawaiians, as well as other ethnic groups, a range of socioeconomic factors need to be addressed. PMID- 29464659 TI - Embryonic Stem Cells in Development and Regenerative Medicine. AB - After progressive improvement in embryonic stem (ES) cell field, several studies have been conducted to explore the usage of ES cells in regenerative medicine. Unlimited self renewal and pluripoteny properties, combined with encouraging preclinical trials, remark that ES cell technology might be promising for clinical practice. ES cells, which can form three germ layers in vitro, are potential candidates to study development at the cellular and molecular level. Understanding the cell fate decision and differentiation processes during development might enable generating functional progenitor cells for tissue restoration. Progression in gene modifications and tissue engineering technology has facilitated the derivation of desired cells for therapy. Success in differentiation protocols and identification the regulatory pathways simplify the research for clinical applications. Although there are established protocols for cell differentiation in vitro and promising preclinical studies in vivo, many challenges need to be adressed before clinical translation. In this review, ES cells are discussed as a model of development in vitro and as a potential candidate for regenerative medicine. This review also dissusses current challenges for ES cell based therapy. PMID- 29464661 TI - An unusual cause of cavitating leukoencephalopathy: ethylmalonic encephalopathy. PMID- 29464660 TI - Association between vitamin D deficiency and risk of thyroid cancer: a case control study and a meta-analysis. AB - PURPOSE: Although vitamin D is reportedly associated with various cancers, the association between vitamin D and thyroid cancer is indefinite. We aimed to investigate whether this association applies to thyroid cancer (TC). METHODS: A total of 276 Chinese Han people were recruited in a current matched case-control study. Multivariable conditional logistic regression was computed to estimate the association between plasma 25(OH)D and papillary thyroid cancer (PTC). In addition, we searched relevant studies in PubMed and Web of Science databases before December 2017 to conduct a meta-analysis. RESULTS: In our case-control study, plasma 25(OH)D concentration was inversely associated with PTC risk (highest tertile vs lowest tertile: adjusted OR = 0.25; 95% CI 0.10, 0.61; Ptrend = 0.003). This association was independent of body mass index and physical activity (all adjusted Pinteraction > 0.05). A total of 11 studies were included in the meta-analysis, among which ten studies have been published and one was our case-control study. Compared with 25(OH)D non-deficient group, the pooled OR of TC was 1.42 (95% CI 1.17, 1.73) in the deficient group. Similarly, blood 25(OH)D levels in patients with TC were tend to be lower than those in the controls (SMD = - 0.20, 95% CI - 0.36, - 0.03). CONCLUSIONS: A high level of circulating 25(OH)D was associated with a decreased TC risk. This association has important significance in public health and should, therefore, be further studied. PMID- 29464662 TI - Clinical routine assessment of palliative care symptoms and concerns and caregiver burden in glioblastoma patients: an explorative field study. AB - The implementation of self-reported outcome measurements into clinical routine was tested to help facilitate early access to palliative care (PC) for glioblastoma (GBM)-patients. Measures detail PC symptoms and concerns and caregiver burden. Between January 2014 and December 2016, a total of 337 GBM patients were discussed during meetings of the neuro-oncology tumor board to examine further treatment options. Each patient, along with their caregivers, was requested to participate in self-assessment using the palliative outcome scale (POS) and the Zarit Burden Interview (ZBI). Analyses encompassed summary statistics, non-parametric tests, visual graphic analysis, content analysis and assessing the utilization of the specialized PC consulting service (SPCCS). Ninety-five (28%) GBM-patients and 71 (21%) caregivers completed the self assessment. Of these, 20 patients and 12 caregivers repeated the assessment at least once more during follow-up. POS total scores were similar in the group of patients with initial diagnosis [10 (0-31)] and those with later disease stages like recurrent diagnosis [9 (0-25)], but ZBI total scores differed [14 (0-51) vs. 24 (2-62)]. Single item analysis demonstrated that anxiety and worries about the future predominated. Caregivers were torn between high engagement in caring and feeling overburdened. Still, requests for the SPCCS showed no increase. Actual implementation of measures like POS and ZBI for detecting PC concerns and caregiver burden with GBM-patients in the field remains challenging as indicated by the limited response rate and lack of increased requests for the SPCCS. Modified clinical routines including strengthening awareness of PC, and allowing proxy-assessment might help to overcome barriers. PMID- 29464663 TI - Incidence and survival of gliomatosis cerebri: a population-based cancer registration study. AB - Gliomatosis cerebri (GC) comprises a rare widespread infiltrating growth pattern of diffuse gliomas. We explored the incidence patterns and survival rates of GC in a population-based registration sample from the Surveillance, Epidemiology and End, Results database (1973-2012). GC cases (n = 176) were identified based on their International Classification of Diseases in Oncology (ICD-O-3) morphology code (9381). We calculated age-adjusted incidence rates (AIR) and evaluated temporal trends. Survival was assessed with Kaplan-Meier curves and Cox regression models. The annual AIR of GC was 0.1/million. We noted increasing trends in the preceding registration years (1973-2002; annually, + 7%) and a tendency of clinical/radiological approaches to substitute the gold-standard histological assessment for diagnosis. GC was diagnosed in the entire age spectrum (range 1-98 years), but higher incidence rates (0.43/million) were noted among the elderly (>= 65 years). A slight male preponderance was identified (male to-female ratio: 1.4). Median overall survival was 9 months with a 5 year survival rate of 18%. Increasing age, primary tumor location not restricted to the cerebral hemispheres and rural residence at diagnosis were identified as negative prognostic factors, whereas receipt of radiotherapy, surgical treatment, race and method of diagnosis were not associated with outcome. This first comprehensive overview of GC epidemiology exemplifies the rarity of the disease, provides evidence for male preponderance and increased incidence among the elderly and shows lower survival rates compared to the published single center reports. Expansion of registration to histological and molecular characteristics would allow emergence of clinical prognostic factors at the population level. PMID- 29464664 TI - Benralizumab: First Global Approval. AB - Kyowa Hakko Kirin, AstraZeneca and subsidiaries are developing benralizumab (FasenraTM)-a humanised anti-interleukin-5 receptor alpha chain (IL-5Ralpha) monoclonal antibody-as a treatment of severe eosinophilic asthma and chronic obstructive pulmonary disease (COPD). Eosinophilia is a characteristic of certain asthma and COPD phenotypes and depletion of eosinophils has demonstrated therapeutic benefit. Benralizumab was recently approved by the US FDA as add-on maintenance therapy for patients with severe asthma who have an eosinophilic phenotype. This article summarizes the milestones in the development of benralizumab leading to this first approval for the treatment of severe eosinophilic asthma. PMID- 29464665 TI - Generic Substitution of Orphan Drugs for the Treatment of Rare Diseases: Exploring the Potential Challenges. AB - Generic drugs are important components of measures introduced by healthcare regulatory authorities to reduce treatment costs. In most patients and conditions the switch from a branded drug to its generic counterpart is performed with no major complications. However, evidence from complex diseases suggests that generic substitution requires careful evaluation in some settings and that current bioequivalence criteria may not always be adequate for establishing the interchangeability of branded and generic products. Rare diseases, also called orphan diseases, are a group of heterogeneous diseases that share important characteristics: in addition to their scarcity, most are severe, chronic, highly debilitating, and often present in early childhood. Finding a treatment for a rare disease is challenging. Thanks to incentives that encourage research and development programs in rare diseases, several orphan drugs are currently available. The elevated cost of orphan drugs is a highly debated issue and a cause of limited access to treatment for many patients. As patent protection and the exclusivity period of several orphan drugs will expire soon, generic versions of orphan drugs should reach the market shortly, with great expectations about their impact on the economic burden of rare diseases. However, consistent with other complex diseases, generic substitution may require thoughtful considerations and may be even contraindicated in some rare conditions. This article provides an overview of rare disease characteristics, reviews reports of problematic generic substitution, and discusses why generic substitution of orphan drugs may be challenging and should be undertaken carefully in rare disease patients. PMID- 29464666 TI - Application of Discrete-Choice Experiment Methods in Tobacco Control: A Systematic Review. AB - BACKGROUND: Economic evidence relating to tobacco control is generally derived from the cost effectiveness of smoking-cessation programs or the economic impact of tobacco-induced disease, based on revealed-preference data. However, empirical estimates from stated-preference data on tobacco users' preferences, smoking behaviour and smoking cessation aids using analytical techniques such as discrete choice experiments (DCEs) could be important for policy decision making in tobacco control. OBJECTIVES: Our objective was to review the practice and utility of DCE methodology across nicotine- and tobacco-related issues, particularly smoking and smoking-cessation behaviour, anti-smoking policies and preferences for smoking-cessation aids. METHODS: We searched the PubMed, MEDLINE and ECONLIT databases for full-text original research articles on tobacco-related issues published between January 2000 and April 2016 that used a DCE method. We summarised the evidence and methodological characteristics of DCEs according to Lancsar and Louviere, 2008. RESULTS: Our review of the 12 eligible studies showed that DCE methodology was used to elicit smoker preferences and to evaluate tobacco-control policies. The majority of the studies were published in the last 5 years. The areas of application were smoking cessation, smoking behaviour, electronic cigarette use, water-pipe smoking and tobacco packaging. Monetary attributes were the most influential attributes in all studies. The design of the DCEs varied. CONCLUSION: DCE studies of tobacco-related issues were methodologically consistent with guidelines proposed for conducting health related DCEs. PMID- 29464667 TI - Economic Evaluation of Bevacizumab for Treatment of Platinum-Resistant Recurrent Ovarian Cancer in Canada. AB - BACKGROUND: Ovarian cancer is a leading cause of cancer-related mortality. Although the disease is relatively rare, it carries a disproportionately large morbidity burden. OBJECTIVE: We conducted a cost-utility analysis from a Canadian public payer perspective to determine the cost effectiveness of bevacizumab, a newly available treatment option for recurrent ovarian cancer. METHODS: Using a 7 year time horizon, a three health-state cohort-based partitioned survival model was developed to assess the cost utility of bevacizumab plus chemotherapy (BEV) versus chemotherapy alone. We reconstructed individual patient data from published Kaplan-Meier curves. Clinical parameters, including progression-free survival and overall survival, were derived from the AURELIA phase III randomized controlled trial. Costs, resource utilization and utility values from recent Canadian sources were used to populate the model. Results were presented using incremental cost-utility ratios (ICURs). Uncertainty was examined through univariate and probabilistic sensitivity analyses. RESULTS: The reconstructed individual patient data matched the AURELIA trial results. Total costs for the BEV and chemotherapy treatment arms were $Can79,086 and $Can54,982, respectively. Total estimated quality-adjusted life-years (QALYs) were 1.1055 and 0.9926 for the BEV and chemotherapy arms, respectively. The ICUR was estimated to be $Can213,424 per QALY gained. At a willingness-to-pay threshold of $Can100,000 per QALY gained, the probability of BEV being cost effective was 0. CONCLUSIONS: The results of our analysis suggest that the addition of bevacizumab to single-agent chemotherapy treatment, while improving patient outcomes, is unlikely to be cost effective in this Canadian patient population. The results also provide some preliminary validation for use of individual patient data-reconstruction techniques in pharmacoeconomic evaluation. PMID- 29464668 TI - Health Technology Assessment for Policy Making in India: Current Scenario and Way Forward. PMID- 29464669 TI - Weighting Health Outcomes by Socioeconomic Position Using Stated Preferences. AB - BACKGROUND: The trade-off that society is willing to make to promote a more equitable distribution of health can be represented as a social welfare function (SWF). SWFs are an economic construct that can be used to illustrate concerns for total health with aversion to inequalities between socioeconomic groups. OBJECTIVE: This study used people's preferences to estimate the shapes of health related SWFs (HRSWFs). We tested the suitability of this method to derive equity weights. METHODS: A questionnaire was used to elicit preferences concerning trade offs between the total level of health and its distribution among two socioeconomic groups. The participant group was a sample of convenience that included a mix of health researchers, academics, clinicians, managers, public servants and research students. The data collected were used to develop HRSWFs with a constant elasticity of substitution. The weight was calculated using the marginal rate of substitution. RESULTS: A marginal health gain to the lowest socioeconomic position (SEP) group was valued 14.1-81.4 times more than a marginal health gain to the high SEP group. CONCLUSIONS: Our results provide evidence to support the idea that the public may be willing to make trade-offs between efficiency and equity, and that they value health gains differently depending on which socioeconomic group receives the health gain. Further evidence is required before such indicative weights have practical value. PMID- 29464670 TI - Reliability and Validity of the Greek Migraine Disability Assessment (MIDAS) Questionnaire. AB - BACKGROUND: The Migraine Disability Assessment (MIDAS) Questionnaire is a reliable and valid instrument for migraine-related disability. Such a tool is needed to quantify migraine-related disability in the Greek population. OBJECTIVE: This validation study aims to assess the test-retest reliability, internal consistency, item discriminant and convergent validity of the Greek translation of the MIDAS. METHODS: Adults diagnosed with migraine completed the MIDAS Questionnaire on two occasions 3 weeks apart to assess reliability, and completed the RAND-36 to assess validity. RESULTS: Participants (n = 152) had a median MIDAS score of 24 and mostly severe disability (58% were grade IV). The test-retest reliability analysis (N = 59) revealed excellent reliability for the total score. Internal consistency was alpha = 0.71 for initial and alpha = 0.82 for retest completion. For item discriminant validity, the correlations between each question and the total score were significant, with high correlations for questions 2-5 (range 0.67 <= r <= 0.79; p < 0.01). For convergent validity, there was significant negative correlation between the total score and all RAND-36 subscales except for 'emotional wellbeing'. The negative correlation indicates that patients with a lower degree of disability according to their MIDAS score tended to have better wellbeing. Psychometric properties are comparable with those of other published validation studies of the MIDAS and the original. Findings on question 1 show that missing work/school days may be closely related with increased affect issues. CONCLUSION: The Greek version of the MIDAS Questionnaire has good reliability and validity. This study allowed for cross cultural comparability of research findings. PMID- 29464671 TI - An Exploratory Study of Long-Term Publicly Waitlisted Bariatric Surgery Patients' Quality of Life Before and 1 Year After Bariatric Surgery, and Considerations for Healthcare Planners. AB - BACKGROUND: Long-term publicly waitlisted bariatric surgery patients typically experience debilitating physical/psychosocial obesity-related comorbidities that profoundly affect their quality of life. OBJECTIVES: We sought to measure quality of-life impacts in a study population of severely obese patients who had multiyear waitlist times and then underwent bariatric surgery. METHODS: Participants were recruited opportunistically following a government-funded initiative to provide bariatric surgery to morbidly obese long-term waitlisted patients. Participants self-completed the EQ-5D-5L and AQoL-8D questionnaires pre and postoperatively. Utility valuations (utilities) and individual/super dimension scores (AQoL-8D only) were generated. RESULTS: Participants' (n = 23) waitlisted time was mean [standard deviation (SD)] 6.5 (2) years, body mass index reduced from 49.3 (9.35) kg/m2 preoperatively to 40.8 (7.01) 1 year postoperatively (p = 0.02). One year utilities revealed clinical improvements (both instruments). AQoL-8D improved significantly from baseline to 1 year, with the change twice that of the EQ-5D-5L [EQ-5D-5L: mean (SD) 0.70 (0.25) to 0.78 (0.25); AQoL-8D: 0.51 (0.24) to 0.67 (0.23), p = 0.04], despite the AQoL-8D's narrower algorithmic range. EQ-5D-5L utility plateaued from 3 months to 1 year. AQoL-8D 1-year utility improvements were driven by Happiness/Coping/Self-worth (p < 0.05), and the Psychosocial super dimension score almost doubled at 1 year (p < 0.05). AQoL-8D revealed a wider dispersion of individual utilities. CONCLUSIONS: Ongoing improvements in psychosocial parameters from 3 months to 1 year post surgery accounted for improvements in overall utilities measured by the AQoL-8D that were not detected by EQ-5D-5L. Selection of a sensitive instrument is important to adequately assess changes in quality of life and to accurately reflect changes in quality-adjusted life-years for cost-utility analyses and resource allocation in a public healthcare resource-constrained environment. PMID- 29464672 TI - Assessing Variation in the Cost of Palivizumab for Respiratory Syncytial Virus Prevention in Preterm Infants. AB - BACKGROUND: The variability in cost of palivizumab treatment, indicated for prevention of respiratory syncytial virus (RSV) infections in high-risk infants, has not been robustly estimated in prior studies. This study aimed to determine the cost variations of palivizumab from a US payer perspective for otherwise healthy preterm infants born 29-35 weeks gestational age (wGA) using infant characteristics and applied dosing regimens. METHODS: Fenton Growth Charts were merged with World Health Organization Child Growth Standards to estimate preterm infant growth patterns. The merged growth chart was applied to infants who received palivizumab from a prospective, observational registry to determine future body weight using each infant's wGA and birth weight. Using quarter 3 (Q3) 2016-Q2 2017 vial cost, treatment costs at monthly dosing intervals were estimated using expected weights and averaged by age to derive expected mean 2016 2017 RSV seasonal costs per infant under various dosing scenarios. RESULTS: Given different dosing scenarios (two to five doses), birth month, and growth patterns for preterm infants 29-35 wGA, the estimated average 2016-2017 seasonal cost of palivizumab treatment ranged from $3221 to $12,568. Outpatient-only cost (excluding first dose at hospital discharge) ranged from $1733 to $11,862. The main drivers of costs were dosing regimen (74% of variance), dosing interacted with birth month (17%), and wGA (6%). CONCLUSION: The considerable variability in the average cost of palivizumab treatment for preterm infants is driven by choice of dosing regimen, wGA, and birth month. Therefore, when estimating the cost of palivizumab, it is important to consider both infant characteristics at each dose and potential dosing regimens. PMID- 29464673 TI - Comparison of Disease-Modifying Therapies for the Management of Multiple Sclerosis: Analysis of Healthcare Resource Utilization and Relapse Rates from US Insurance Claims Data. AB - BACKGROUND: Data on comparative healthcare resource utilization and costs associated with the newer oral disease-modifying therapies (DMTs) for managing relapsing-remitting multiple sclerosis (MS) in routine clinical practice are limited. The purpose of this study was to estimate healthcare resource utilization, costs, and relapse rates in the year after initiating treatment with dimethyl fumarate (DMF), interferon (IFN)-beta, glatiramer acetate (GA), teriflunomide, or fingolimod in routine clinical practice for patients with MS who did not receive a DMT in the previous year. METHODS: Patients initiating DMF, IFNbeta, GA, teriflunomide, or fingolimod were identified based on claims data from 2012 to 2015 in the Truven MarketScan Commercial Claims Databases (n = 4194). Healthcare resource utilization assessment included the proportion of patients who were hospitalized, or had emergency room (ER) or urgent care (UC) visits. Healthcare costs were estimated for 1 year before and 1 year after DMT initiation. Relapse episodes were identified based on a published claims-based algorithm and clinical input from the research investigators. RESULTS: After DMT initiation, significant reductions in the proportions of patients who were hospitalized or requiring ER/UC visits were observed in all patient cohorts (p < 0.001 and p < 0.05, respectively). Non-prescription medical costs decreased after DMT initiation, with the largest decrease observed in the DMF cohort (US$5761 reduction, p < 0.0001). Reductions in non-prescription medical costs were associated with decreased use of outpatient services and inpatient hospital stays, and have the potential to partially offset DMT costs. CONCLUSIONS: DMT initiation is associated with reductions in healthcare resource utilization and non-prescription medical costs in routine clinical practice. PMID- 29464674 TI - Attention toward contexts modulates context-specificity of behavior in human predictive learning: Evidence from the n-back task. AB - According to the attentional theory of context processing (ATCP), learning becomes context specific when acquired under conditions that promote attention toward contextual stimuli regardless of whether attention deployment is guided by learning experience or by other factors unrelated to learning. In one experiment with humans, we investigated whether performance in a predictive learning task can be brought under contextual control by means of a secondary task that was unrelated to predictive learning, but supposed to modulate participants' attention toward contexts. Initially, participants acquired cue-outcome relationships presented in contexts that were each composed of two elements from two dimensions. Acquisition training in the predictive learning task was combined with a one-back task that required participants to match across consecutive trials context elements belonging to one of the two dimensions. During a subsequent test, we observed that acquisition behavior in the predictive learning task was disrupted by changing the acquisition context along the dimension that was relevant for the one-back task, while there was no evidence for context specificity of predictive learning when the acquisition context was changed along the dimension that was irrelevant for the one-back task. Our results support the generality of the principles advocated by ATCP. PMID- 29464675 TI - Outpatient parenteral antibiotic therapy in a suburban tertiary referral centre in Australia over 10 years. AB - PURPOSE: Outpatient parenteral antibiotic therapy (OPAT) is a widely accepted and safe therapeutic option for carefully selected patients. This study reviewed the practice of an OPAT service in a large Australian tertiary teaching hospital in Western Sydney over a 10-year period. METHOD: Data were retrieved from a prospectively maintained electronic database which included information on patient demographics, clinical diagnosis, microbiological identity, antimicrobial therapy, complications and readmissions. Data were analysed using descriptive statistics. RESULTS: There were 3435 referrals made to the service between January 2004 and June 2014, amounting to 25,289 antibiotic days. The most frequent referral was for Skin and Soft Tissue Infections (SSTIs), 61.28%, followed by Bone and Joint Infections (BJIs), 15.30%. The most common organism identified was methicillin-sensitive Staphylococcus aureus. Readmission was uncommon (5.15%), with the highest rate of readmission noted for Cardiovascular System Infections (16.67%) followed by BJIs (10.31%). Line infection, aseptic thrombophlebitis and drug hypersensitivity or reaction were the cause of 68.55% of all complications. There was a decline in line-related complications throughout the study period. CONCLUSION: OPAT service is in increasing demand in Australia, providing a significant relief in in-hospital days. Growth in referrals was seen not only with SSTIs and BJIs, but also a diverse range of other infective entities with limited literature in its treatment in an OPAT setting. This study highlights the need to improve data collection, develop risk stratification strategies and standardisation of OPAT services in Australia. PMID- 29464676 TI - Further Evidence of the Association of the Diacylglycerol Kinase Kappa (DGKK) Gene With Hypospadias. AB - PURPOSE: Hypospadias is a common developmental anomaly of the male external genitalia. In previous studies conducted on West European, Californian, and Han Chinese populations the relationship between polymorphic variants of the diacylglycerol kinase kappa (DGKK) gene and hypospadias have been reported. The aim was to study the possible associations between polymorphic variants of the DGKK gene and hypospadias using an independent sample of the Polish population. MATERIALS AND METHODS: Ten single nucleotide polymorphisms in DGKK, which were reported to have an impact on the risk of hypospadias in other populations, were genotyped using high-resolution melting curve analysis in a group of 166 boys with isolated anterior (66%) and middle (34%) forms of hypospadias and 285 properly matched controls without congenital anomalies. RESULTS: Two DGKK variants rs11091748 and rs12171755 were associated with increased risk of hypospadias in the Polish population. These results were statistically significant, even after applying the Bonferroni correction for multiple comparisons (P < .005). All the tested nucleotide variants were involved in haplotype combinations associated with hypospadias. The global p-values for haplotypes comprising of rs4143304-rs11091748, rs11091748-rs17328236, rs1934179 rs4554617, rs1934183-rs1934179-rs4554617 and rs12171755-rs1934183-rs1934179 rs4554617 were statistically significant, even after the permutation test correction. CONCLUSION: Our study provides strong evidence of an association between DGKK nucleotide variants, haplotypes and hypospadias susceptibility. PMID- 29464677 TI - Laparoscopic Pyelolithotomy for Management of Complete Staghorn Stone of An Ectopic Pelvic Kidney. AB - A 40-year-old man was referred to our urology clinic due to vague abdominal pain and hematuria. Computed tomography (CT) without contrast material visualized an ectopic kidney in the left iliac fossa with a complete staghorn stone. Under general anesthesia, operation was done in supine position with a gentle lateral elevation on the right side. The surgeon stands on the right side of the patient. First, a 12 mm port was inserted at the umbilicus using the Hasson technique. After creation of pneumoperitoneum, operation was done by three 5 mm trocars were arranges as paraumbilical, the point between umbilicus and inguinal canal at left and right side.A vertical pyelotomy incision was made over the anterior pelvic wall and then extended to a cross figure. The stone extracted intact with a laparoscopic stone grasper and placed in endobag. A short double J stent was placed via the pyelotomy incision and renal pelvis was closed using continuous 4.0 vicryl sutures. He was discharged from hospital after 3 days without any complication.

PMID- 29464679 TI - Prognostic significance of body mass index and other tumor and patient characteristics in non-metastatic renal cell carcinoma. AB - PURPOSE: In this retrospective study, we aimed to investigate the prognostic effect of body mass index (BMI) in localized renal cell carcinoma (RCC) cases who underwent surgical treatment. Furthermore, the assessment of various patient and tumor characteristics and surgical methods on survival has been identified as additional targets. MATERIALS AND METHODS: Three hundred and eighty patients with localised, non-metastatic, unilateral RCC who underwent radical or partial nephrectomy in our clinic between January 2007 and December 2016 were enrolled in this study. Age, gender, height, weight, BMI, operation type and method, pathology results and tumor stage of the patients were recorded. Patients were divided into 3 groups according to body mass index (BMI): Normal weight(< 25 kg/m2), overweight (25-30 kg/m2) and obese (>30 kg/m2) as groups 1, 2 and 3, respectively. We analyzed the relation between the BMI, gender, smoking, hypertension, type and method of surgical treatment, histologic subtype, tumor stage, estimated glomerular filtration rate (eGFR) and cancer-specific (CSS) and recurrence free survival (RFS). All data analysis was performed using SPSS(r) Statistical Software for Windows (Version 13.0) and a P value less than 0.05 was considered to be significant. RESULTS: The effect of BMI on both CSS and RFS was statistically significant (P < .001). There was also a significant relation between smoking, operation type (partial/radical), eGFR and tumor stage and CSS and RFS. CONCLUSION: Our findings show that overweight and obese RCC patients according to the BMI have a more favorableprognosis. Multicenter, prospective studies with more cases and longer oncological follow-up period are needed to support these findings. PMID- 29464680 TI - Comparative Results of Transurethral Incision with Transurethral Resection of The Prostate in Renal Transplant Recipients with Benign Prostate Hyperplasia. AB - PURPOSE: The aim of this study is to compare the results of transurethral incision of the prostate (TUIP) and transurethral resection of the prostate (TURP) for the surgical treatment of benign prostate hyperplasia (BPH) in patients with renal transplantation. MATERIALS AND METHODS: Between April 2009 and May 2016, BPH patients with renal transplants whose prostate volumes were less than 30 cm3 were treated surgically. Forty-seven patients received TURP and 32 received TUIP. The patients' age, duration of dialysis, duration between transplant and TURP/TUIP, preoperative and postoperative serum creatinine (SCr), International Prostate Symptom Score (IPSS), maximum flow rate (Qmax) and postvoidresidual volume (PVR) were recorded. At 1-,6- and 12-month follow-up, early and long-term complications were assessed. Results were evaluated retrospectively. RESULTS: In both groups, SCr, PVR and IPSS decreased significantly after the operation, while Qmax increased significantly (P < .001). There was no difference between the two groups in terms of increase in Qmax and decrease in IPSS, SCr and PVR (P = .89, P = .27, P = .08, and P = .27). Among postoperative complications, urinary tract infection (UTIs) and retrograde ejaculation (RE) rates were higher in the TURP group than the TUIP group (12.7% versus 6.2% and 68.1% versus 25%,respectively), whereas urethral strictures were more prevalent in the TUIP group (12.5% versus 6.3%). CONCLUSION: For the treatment of BPH in renal transplant patients with a prostate volume less than 30 cm3, bothTUIP and TURP are safe and effective. PMID- 29464681 TI - An Unusual Complication of Suprapubic Catheter Migration into the Left Ureter. AB - Suprapubic cystostomy is a widely employed procedure that is used to drain the bladder. Despite being a safe procedure, suprapubic cystostomy has been reported to present multiple intra- and postoperative complications. Serious and unusual complications can occur during changing of the suprapubic catheter (SPC) in patients with neuropathic bladder. In this work, we report an elderly patient with neuropathic bladder suffering from an unusual complication involving migration of the SPC into the ureter during changing of the SPC, leading to ureteric obstruction and left pyelonephritis. PMID- 29464682 TI - Comparison of Partial and Radical Laparascopic Nephrectomy: Long-Term Outcomes for Clinical T1b Renal Cell Carcinoma. AB - PURPOSE: To compare the long-term clinical and oncologic outcomes in patients treated with laparoscopic partial nephrectomy (LPN) and laparoscopic radial nephrectomy (LRN) for clinical T1b renal cell carcinoma. MATERIALS AND METHODS: We retrospectively reviewed the records of all patients who underwent LPN or LRN for a single clinical T1b tumor between January 2005 and January 2012, an actual follow-up of 2-year or greater was available in 39 and 160 after LPN and LRN, respectively. Survival was calculated using the Kaplan-Meier method. Multivariable Cox regression analysis was done to assess predictors of survival. RESULTS: The two cohorts of patients were similar in age, sex, body-mass index and preoperative eGFR. There were no differences in tumors size (4.97 vs 5.29cm, P = .08), and pathological stage distribution between the two cohorts. The median follow-up after LPN and LRN were 67 (range: 18-118) and 70 (19-120) months, respectively. For LPN versus LRN, 5-years overall and cancer specific survival rates were 93.33% vs 85.69% and 96.00% vs 91.35%, respectively. For LPN versus LRN, 10-years overall and cancer specific survival rates were 85.56% vs73.41% and 88.00% vs 82.85%, respectively. On multivariate analysis, patients' age, ASA score and pathological stage were the major factors affecting overall survival, and patients' age and pathological stage were associated with cancer specific survival. The percent decrease in glomerular filtration rate was significantly lower in the LRN group at early and last followup. CONCLUSION: LPN is an effective treatment option in appropriately selected patients with cT1b RCC. It provides 5-year, 10-year overall survival and cancer specific survival comparable to those of LRN as well as better preservation of renal function than LRN. Overall survival and cancer specific survival are associated with nonmodifiable factors but not by the choice of operative technique. PMID- 29464683 TI - Autophosphorylation of the carboxyl-terminal domain is not required for oncogenic transformation by lung-cancer derived EGFR mutants. AB - Aberrant activation of cancer-derived mutants of the epidermal growth factor receptor (EGFR) is closely associated with cancer pathogenesis and is thought to be mediated through multiple tyrosine phosphorylations within the C-terminal domain. Here, we examined the consequences of the loss of these C-terminal phosphorylation sites on cellular transformation in the context of lung-cancer derived L858R, exon 19 deletion and exon 20 insertion mutant EGFR. Oncogenic EGFR mutants with substitution of the 10 potential C-terminal tyrosine autophosphorylation sites for phenylalanine (CYF10) were still able to promote anchorage-independent growth in soft agar at levels comparable to the parental L858R or exon19 deletion or exon 20 insertion mutants with intact autophosphorylation sites. Furthermore, these CYF10 mutants retained the ability to transform Ba/F3 cells in the absence of IL-3. Bead-based phosphorylation and immunoprecipitation analyses demonstrated that key EGFR-associated proteins including Grb2 and PLC-gamma-are neither phosphorylated nor bound to CYF10 mutants in transformed cells. Taken together, we conclude that tyrosine phosphorylation is not required for oncogenic activity of lung-cancer-derived mutant EGFR, suggesting these mutants can lead to cellular transformation by an alternative mechanism independent of EGFR phosphorylation. PMID- 29464685 TI - Estimating Sex Using Metric Analysis of the Scapula by Postmortem Computed Tomography. AB - Postmortem computed tomography (CT) has been extensively used in the last decade for identification purposes and in various anthropologic studies. Postmortem CT measurements of scapulae, analyzed using logistic discriminant function developed in this study, showed 94.5% accuracy in estimating sex. Data analyzed using the Dabbs and Moore-Jansen (2010) discriminant function and the discriminant function generated in this study provided nearly identical results with disagreement in only one case. Height and weight were not statically significant in sex prediction. The results of this study show that data obtained from volume rendered postmortem CT images can be considered reliable and treated as a practical option to standard anthropological methods, especially in mass fatalities as a rapid triage tool for sex determination. PMID- 29464686 TI - Fatal Complications of Aesthetic Techniques: The Gluteal Region. AB - Cosmetic procedures are common and utilize many techniques to obtain aesthetically good outcomes for patient satisfaction with acceptable safety standards. Cosmetic procedures that involve the gluteal region are becoming increasingly popular as various procedures can target the gluteal region such as liposuction, tumescent liposuction, cosmetic filler injections, autologous fat transfer, depot drug delivery, and implants. Complications of cosmetic gluteal procedures can be localized or systemic with systemic complications being responsible for most deaths. These reported systemic complications include sepsis, thromboembolism, fat embolism with or without fat embolism syndrome, macroscopic fat embolism, anesthesia-related and blood volume abnormalities. We herein report 10 deaths due to elective gluteal cosmetic procedures. Autologous fat transfer (fat grafting, lipoinjection) following liposuction resulted in 8 of 10 fatal outcomes of the gluteal aesthetic procedures. A comprehensive discussion of gluteal anatomy, gluteal contouring procedures, and the approach to such cases is presented along with the autopsy findings of the reported cases. PMID- 29464684 TI - Neuregulin directed molecular mechanisms of visual cortical plasticity. AB - Experience-dependent critical period (CP) plasticity has been extensively studied in the visual cortex. Monocular deprivation during the CP affects ocular dominance, limits visual performance, and contributes to the pathological etiology of amblyopia. Neuregulin-1 (NRG1) signaling through its tyrosine kinase receptor ErbB4 is essential for the normal development of the nervous system and has been linked to neuropsychiatric disorders such as schizophrenia. We discovered recently that NRG1/ErbB4 signaling in PV neurons is critical for the initiation of CP visual cortical plasticity by controlling excitatory synaptic inputs onto PV neurons and thus PV-cell mediated cortical inhibition that occurs following visual deprivation. Building on this discovery, we review the existing literature of neuregulin signaling in developing and adult cortex and address the implication of NRG/ErbB4 signaling in visual cortical plasticity at the cellular and circuit levels. NRG-directed research may lead to therapeutic approaches to reactivate plasticity in the adult cortex. PMID- 29464687 TI - A Case of Self-Enucleation in an Incarcerated Patient: Case Report and Review of Literature. AB - Self-enucleation is a severe form of self-injurious behavior which presents as an ophthalmologic and psychiatric emergency. It is usually known to occur with untreated psychosis, however, there have been reports of self-enucleation across various psychopathologies. We review a case documenting self-enucleation in the forensic setting in a patient with an unusual presentation and cluster of psychotic symptoms. Literature was reviewed using PubMed/Medline databases with key terms: "forensic science," "forensic psychiatry," "auto-enucleation," "self enucleation," "Oedipism," "self-harm." This case is unique as it offers an alternative presentation to those most commonly depicted in current literature, helps highlight the sparsity of literature depicting self-enucleation in the forensic setting, and stimulates discussion around various potential differential diagnoses, management strategies and complications of self-enucleation within the forensic setting. It is prudent to emphasize need for aggressive and collaborative treatment for the forensic population regardless of psychopathology, presentation, or propensity for secondary gain. PMID- 29464688 TI - It takes a few to tango: changing climate and fire regimes can cause regeneration failure of two subalpine conifers. AB - Environmental change is accelerating in the 21st century, but how multiple drivers may interact to alter forest resilience remains uncertain. In forests affected by large high-severity disturbances, tree regeneration is a resilience linchpin that shapes successional trajectories for decades. We modeled stands of two widespread western U.S. conifers, Douglas-fir (Pseudotsuga menziesii var. glauca), and lodgepole pine (Pinus contorta var. latifolia), in Yellowstone National Park (Wyoming, USA) to ask (1) What combinations of distance to seed source, fire return interval, and warming-drying conditions cause postfire tree regeneration failure? (2) If postfire tree regeneration was successful, how does early tree density differ under future climate relative to historical climate? We conducted a stand-level (1 ha) factorial simulation experiment using the individual-based forest process model iLand to identify combinations of fire return interval (11-100 yr), distance to seed source (50-1,000 m), and climate (historical, mid-21st century, late-21st century) where trees failed to regenerate by 30-yr postfire. If regeneration was successful, we compared stand densities between climate periods. Simulated postfire regeneration were surprisingly resilient to changing climate and fire drivers. Douglas-fir regeneration failed more frequently (55%) than lodgepole pine (28% and 16% for non-serotinous and serotinous stands, respectively). Distance to seed source was an important driver of regeneration failure for Douglas-fir and non-serotinous lodgepole pine; regeneration never failed when stands were 50 m from a seed source and nearly always failed when stands were 1 km away. Regeneration of serotinous lodgepole pine only failed when fire return intervals were <=20 yr and stands were far (1 km) from a seed source. Warming climate increased regeneration success for Douglas-fir but did not affect lodgepole pine. If regeneration was successful, postfire density varied with climate. Douglas-fir and serotinous lodgepole pine regeneration density both increased under 21st-century climate but in response to different climate variables (growing season length vs. cold limitation). Results suggest that, given a warmer future with larger and more frequent fires, a greater number of stands that fail to regenerate after fires combined with increasing density in stands where regeneration is successful could produce a more coarse-grained forest landscape. PMID- 29464689 TI - Distinction of Fly Artifacts from Human Blood using Immunodetection. AB - Insect stains produced by necrophagous flies are indistinguishable morphologically from human bloodstains. At present, no diagnostic tests exist to overcome this deficiency. As the first step toward developing a chemical test to recognize fly artifacts, polyclonal antisera were generated in rats against three distinct antigenic sequences of fly cathepsin D-like proteinase, an enzyme that is structurally distinct in cyclorrhaphous Diptera from other animals. The resulting rat antisera bound to artifacts produced by Protophormia terraenovae and synthetic peptides used to generate the polyclonal antisera, but not with any type of mammalian blood tested in immunoassays. Among the three antisera, anti md3 serum displayed the highest reactivity for fly stains, demonstrated cross reactivity for all synthetic peptides representing antigenic sequences of the mature fly enzyme, and bound artifacts originating from the fly digestive tract. Further work is needed to determine whether the antisera are suitable for non laboratory conditions. PMID- 29464690 TI - BIS monitoring versus clinical assessment for sedation in mechanically ventilated adults in the intensive care unit and its impact on clinical outcomes and resource utilization. AB - BACKGROUND: Patients admitted to intensive care and on mechanical ventilation, are administered sedative and analgesic drugs to improve both their comfort and interaction with the ventilator. Optimizing sedation practice may reduce mortality, improve patient comfort and reduce cost. Current practice is to use scales or scores to assess depth of sedation based on clinical criteria such as consciousness, understanding and response to commands. However these are perceived as subjective assessment tools. Bispectral index (BIS) monitors, which are based on the processing of electroencephalographic signals, may overcome the restraints of the sedation scales and provide a more reliable and consistent guidance for the titration of sedation depth.The benefits of BIS monitoring of patients under general anaesthesia for surgical procedures have already been confirmed by another Cochrane review. By undertaking a well-conducted systematic review our aim was to find out if BIS monitoring improves outcomes in mechanically ventilated adult intensive care unit (ICU) patients. OBJECTIVES: To assess the effects of BIS monitoring compared with clinical sedation assessment on ICU length of stay (LOS), duration of mechanical ventilation, any cause mortality, risk of ventilator-associated pneumonia (VAP), risk of adverse events (e.g. self-extubation, unplanned disconnection of indwelling catheters), hospital LOS, amount of sedative agents used, cost, longer-term functional outcomes and quality of life as reported by authors for mechanically ventilated adults in the ICU. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, CINAHL, ProQuest, OpenGrey and SciSearch up to May 2017 and checked references citation searching and contacted study authors to identify additional studies. We searched trial registries, which included clinicaltrials.gov and controlled-trials.com. SELECTION CRITERIA: We included all randomized controlled trials comparing BIS versus clinical assessment (CA) for the management of sedation in mechanically ventilated critically ill adults. DATA COLLECTION AND ANALYSIS: We used Cochrane's standard methodological procedures. We undertook analysis using Revman 5.3 software. MAIN RESULTS: We identified 4245 possible studies from the initial search. Of those studies, four studies (256 participants) met the inclusion criteria. One more study is awaiting classification. Studies were, conducted in single-centre surgical and mixed medical-surgical ICUs. BIS monitor was used to assess the level of sedation in the intervention arm in all the studies. In the control arm, the sedation assessment tools for CA included the Sedation-Agitation Scale (SAS), Ramsay Sedation Scale (RSS) or subjective CA utilizing traditional clinical signs (heart rate, blood pressure, conscious level and pupillary size). Only one study was classified as low risk of bias, the other three studies were classified as high risk.There was no evidence of a difference in one study (N = 50) that measured ICU LOS (Median (Interquartile Range IQR) 8 (4 to 14) in the CA group; 12 (6 to 18) in the BIS group; low-quality evidence).There was little or no effect on the duration of mechanical ventilation (MD -0.02 days (95% CI -0.13 to 0.09; 2 studies; N = 155; I2 = 0%; low-quality evidence)). Adverse events were reported in one study (N = 105) and the effects on restlessness after suction, endotracheal tube resistance, pain tolerance during sedation or delirium after extubation were uncertain due to very low-quality evidence. Clinically relevant adverse events such as self-extubation were not reported in any study. Three studies reported the amount of sedative agents used. We could not measure combined difference in the amount of sedative agents used because of different sedation protocols and sedative agents used in the studies. GRADE quality of evidence was very low. No study reported other secondary outcomes of interest for the review. AUTHORS' CONCLUSIONS: We found insufficient evidence about the effects of BIS monitoring for sedation in critically ill mechanically ventilated adults on clinical outcomes or resource utilization. The findings are uncertain due to the low- and very low-quality evidence derived from a limited number of studies. PMID- 29464691 TI - A pilot study of hyperoxemia on neurological injury, inflammation and oxidative stress. AB - BACKGROUND: Normobaric hyperoxia is used to alleviate secondary brain ischaemia in patients with traumatic brain injury (TBI), but clinical evidence is limited and hyperoxia may cause adverse events. METHODS: An open label, randomised controlled pilot study comparing blood concentrations of reactive oxygen species (ROS), interleukin 6 (IL-6) and neuron-specific enolase (NSE) between two different fractions of inspired oxygen in severe TBI patients on mechanical ventilation. RESULTS: We enrolled 27 patients in the Fi O2 0.40 group and 38 in the Fi O2 0.70 group; 19 and 23 patients, respectively, completed biochemical analyses. In baseline, there were no differences between Fi O2 0.40 and Fi O2 0.70 groups, respectively, in ROS (64.8 nM [22.6-102.1] vs. 64.9 nM [26.8-96.3], P = 0.80), IL-6 (group 92.4 pg/ml [52.9-171.6] vs. 94.3 pg/ml [54.8-133.1], P = 0.52) or NSE (21.04 ug/l [14.0-30.7] vs. 17.8 ug/l [14.1-23.9], P = 0.35). ROS levels did not differ at Day 1 (24.2 nM [20.6-33.5] vs. 29.2 nM [22.7-69.2], P = 0.10) or at Day 2 (25.4 nM [21.7-37.4] vs. 47.3 nM [34.4-126.1], P = 0.95). IL-6 concentrations did not differ at Day 1 (112.7 pg/ml [65.9-168.9) vs. 83.9 pg/ml [51.8-144.3], P = 0.41) or at Day 3 (55.0 pg/ml [34.2-115.6] vs. 49.3 pg/ml [34.4 126.1], P = 0.95). NSE levels did not differ at Day 1 (15.9 ug/l [9.0-24.3] vs. 15.3 ug/l [12.2-26.3], P = 0.62). There were no differences between groups in the incidence of pulmonary complications. CONCLUSION: Higher fraction of inspired oxygen did not increase blood concentrations of markers of oxidative stress, inflammation or neurological injury or the incidence of pulmonary complications in severe TBI patients on mechanical ventilation.

In 1973 David Musto published his book, The American Disease: Origins of Narcotic Control, which described the problem as dating back to the time of the Civil War. Continued attempts to address it through legislation, law enforcement, prevention, treatment, and the development of less abuseable pain relievers have shown limited success. PMID- 29464693 TI - The Role of Postmortem Computed Tomography in the Evaluation of Strangulation Deaths. AB - We explored the value of postmortem computed tomography (PMCT) to augment autopsy in evaluating strangulation fatalities. A literature search identified 16 studies describing autopsy findings in 576 deaths and two studies describing autopsy and PMCT findings in six deaths. Similar cases were identified from our institution, yielding 130 deaths with autopsy findings and 14 deaths with both autopsy and PMCT findings. The presence of laryngohyoid fracture and soft tissue hemorrhage was compared from autopsy and autopsy+PMCT cases. The detection rates of fractures in autopsy and autopsy+PMCT cases were not significantly different. PMCT identified all fractures observed at autopsy and five fractures not identified. While PMCT may not detect soft tissue injuries in decomposed remains or subtle internal hemorrhages in neck injury, it is equally able to detect bony injuries as autopsy and might surpass autopsy in detecting subtle fractures. We conclude PMCT is useful to supplement autopsy in strangulation cases. PMID- 29464694 TI - The evolution of floral signals in relation to range overlap in a clade of California Jewelflowers (Streptanthus s.l.). AB - Because of their function as reproductive signals in plants, floral traits experience distinct selective pressures related to their role in speciation, reinforcement, and prolonged coexistence with close relatives. However, few studies have investigated whether population-level processes translate into detectable signatures at the macroevolutionary scale. Here, we ask whether patterns of floral trait evolution and range overlap across a clade of California Jewelflowers reflect processes hypothesized to shape floral signal differentiation at the population level. We found a pattern of divergence in floral scent composition across the clade such that close relatives had highly disparate floral scents given their age. Accounting for range overlap with close relatives explained additional variation in floral scent over time, with sympatric species pairs having diverged more than allopatric species pairs given their age. However, three other floral traits (flower size, scent complexity and flower color) did not fit these patterns, failing to deviate from a null Brownian motion model of evolution. Together, our results suggest that selection for divergence among close relatives in the composition of floral scents may play a key, sustained role in mediating speciation and coexistence dynamics across this group, and that signatures of these dynamics may persist at the macroevolutionary scale. PMID- 29464695 TI - Time Radically Alters Ex Situ Evidentiary Soil 16S Bacterial Profiles Produced Via Next-Generation Sequencing,. AB - Previous research has revealed the potential of soil bacterial profiling for forensic purposes; however, investigators have not thoroughly examined fluctuations in microbial profiles from soil aged on evidence. In this research, soils collected from multiple habitats were placed on evidence items and sampled over time, and then bacterial profiles were generated via next-generation sequencing of the 16S rRNA locus. Bacterial abundance charts and nonmetric multidimensional scaling plots provided visual representation of bacterial profiles temporally, while supervised classification was used to statistically associate evidence to a source. The ex situ evidence soils displayed specific, consistent taxonomic changes as they aged, resulting in their drift in multidimensional space, but never toward a different habitat. Ninety-five percent of the 364 evidentiary profiles statistically classified to the correct habitat, with misclassification generally stemming from evidence type and increased age. Ultimately, understanding bacterial changes that occur temporally in ex situ soils should enhance their use in forensic investigations. PMID- 29464698 TI - Dual-guild herbivory disrupts predator-prey interactions in the field. AB - Plant defenses often mediate whether competing chewing and sucking herbivores indirectly benefit or harm one another. Dual-guild herbivory also can muddle plant signals used by specialist natural enemies to locate prey, further complicating the net impact of herbivore-herbivore interactions in naturally diverse settings. While dual-guild herbivore communities are common in nature, consequences for top-down processes are unclear, as chemically mediated tri trophic interactions are rarely evaluated in field environments. Combining observational and experimental approaches in the open field, we test a prediction that chewing herbivores interfere with top-down suppression of phloem feeders on Brassica oleracea across broad landscapes. In a two-year survey of 52 working farm sites, we found that parasitoid and aphid densities on broccoli plants positively correlated at farms where aphids and caterpillars rarely co-occurred, but this relationship disappeared at farms where caterpillars commonly co occurred. In a follow-up experiment, we compared single and dual-guild herbivore communities at four local farm sites and found that caterpillars (P. rapae) caused a 30% reduction in aphid parasitism (primarily by Diaeretiella rapae), and increased aphid colony (Brevicoryne brassicae) growth at some sites. Notably, in the absence of predators, caterpillars indirectly suppressed, rather than enhanced, aphid growth. Amid considerable ecological noise, our study reveals a pattern of apparent commensalism: herbivore-herbivore facilitation via relaxed top-down suppression. This work suggests that enemy-mediated apparent commensalism may override constraints to growth induced by competing herbivores in field environments, and emphasizes the value of placing chemically mediated interactions within their broader environmental and community contexts. PMID- 29464699 TI - Immune checkpoint blockade combined with IL-6 and TGF-beta inhibition improves the therapeutic outcome of mRNA-based immunotherapy. AB - Improved understanding of cancer immunology has provided insight into the phenomenon of frequent tumor recurrence after initially successful immunotherapy. A delicate balance exists between the capacity of the immune system to control tumor growth and various resistance mechanisms that arise to avoid or even counteract the host's immune system. These resistance mechanisms include but are not limited to (i) adaptive expression of inhibitory checkpoint molecules in response to the proinflammatory environment and (ii) amplification of cancer stem cells, a small fraction of tumor cells possessing the capacity for self-renewal and mediating treatment resistance and formation of metastases after long periods of clinical remission. Several individual therapeutic agents have so far been developed to revert T-cell exhaustion or disrupt the cross-talk between cancer stem cells and the tumor-promoting microenvironment. Here, we demonstrate that a three-arm combination therapy-consisting of an mRNA-based vaccine to induce antigen-specific T-cell responses, monoclonal antibodies blocking inhibitory checkpoint molecules (PD-1, TIM-3, LAG-3), and antibodies targeting IL-6 and TGF beta-improves the therapeutic outcome in subcutaneous TC-1 tumors and significantly prolongs survival of treated mice. Our findings point to a need for a rational development of multidimensional anticancer therapies, aiming at the induction of tumor-specific immunity and simultaneously targeting multiple resistance mechanisms. PMID- 29464700 TI - Septic Cavernous Sinus Thrombosis Following a Minor Head Injury: A Rare Cause of Medico-Legal Death. AB - Septic cavernous sinus thrombosis (SCST) is an uncommon consequence of head and face infection, but a rare complication after craniofacial fracture. In this case, SCST developed in a 13-year-old girl following a minor fall during volleyball, with impact and resulting abrasive contusion of the left forehead. She developed watery rhinorrhea, progressive headache, fever, nausea, vomiting, and left proptosis with blurred vision, and was admitted to hospital 3 days after injury. Drowsiness, high-grade fever, severe headache, left ocular pain with marked periorbital swelling, and paralysis of extraocular eye movements developed. Computed tomography scan identified left sphenoid and ethmoid sinusitis, a posterior clinoid fracture, and septic cavernous sinus thrombosis. She died after 10 days of in-hospital antibiotic therapy. Death was due to Staphylococcus aureus sepsis with septic pulmonary thromboemboli due to suppurative meningitis and cerebral infarction, due to SCST following apparently minor blunt head injury from an accidental fall. PMID- 29464701 TI - Analysis of Class Characteristics of Reciprocating Saws. AB - Criminal dismemberment is accomplished using a variety of tools and frequently used to dispose or facilitate the transport of human remains in an attempt to hinder forensic investigation. The present research examined features that may differentiate cuts made in bone by various commercially available reciprocating saw blades. The partial limbs of adult white-tailed deer (Odocoileus virginianus) were used as a proxy for human remains and were cut using five reciprocating saw blades and a hand-powered hacksaw. The resulting false start and complete kerfs were examined macroscopically and microscopically. Kerf characteristics in which significant differences (p <= 0.05) between reciprocating blades were noted including minimum kerf width, kerf false start shape, presence of cut surface drift and harmonics, exit chipping size, and striation regularity. Interblade differences generally reflect class characteristics previously established for hand-powered blades. The present research may aid in the identification of reciprocating saw use in forensic contexts.

One machete and two katanas were used to produce cut marks on Sus scrofa rib, flat and long bones. Fifty-nine cuts were produced by the katanas and 38 by the machete. The presence of flaking, feathering, peeling, micropeeling, chattering, microcurvature, scoop defect, and exit notch was noted, and bivariate associations between each characteristic and weapon type were assessed using Pearson's chi-square tests for independence and logistic regression models developed. Significant predictors for machete cut marks are scoop defect for rib bones (correct classification 93%), micropeeling in flat bones, chattering on flat and long bones (all p < 001) and for the katana, microcurvature (p < 004) and exit notch on flat and long bones (p < 001; correct classification 96% and 100%, respectively). The identified bivariate associations and final logistic regression models may be utilized in forensic investigations when identifying hacking trauma. PMID- 29464703 TI - A Comparison Among Three Multiplex Y-STR Profiling Kits for Sexual Assault Cases. AB - Biological evidence of sexual assault is one of the most difficult sample types to analyze in forensic laboratories. Y-STR markers are thus a valuable tool for analyzing these samples. The aim of this project was to compare three Y-STR commercial kits by analyzing their amplification performance on casework samples. Overall, 247 trace samples were analyzed with a Yfiler(r) Plus PCR Amplification Kit (Applied Biosystems), PowerPlex(r) Y23 (Promega(r) ) System and AmpFLSTR(r) YfilerTM PCR Amplification Kit (Applied Biosystems). Comparing the amplification performance of the three kits, the first two were significantly more sensitive than the latter (p < 0.001). For samples, with a male DNA quantity less than 0.5 ng, the PowerPlex Y23(r) kit was the most sensitive and best performing kit, followed by the Yfiler(r) Plus kit (p = 0.009). In conclusion, the Yfiler(r) Plus and PowerPlex Y-23(r) kits are viable alternatives to older kits for samples with low amounts of male DNA. PMID- 29464704 TI - Epilepsy with auditory features: Long-term outcome and predictors of terminal remission. AB - OBJECTIVE: To assess the long-term outcome of epilepsy with auditory features (EAF) and to identify the clinical predictors for prognosis. METHODS: The study involved consecutive EAF patients with a follow-up of >=5 years. Terminal remission (TR) was defined as a period of >=5 consecutive years of seizure freedom at the last follow-up. We used Kaplan-Meier estimate to calculate the cumulative time-dependent probability of conversion to TR. Log-rank test and multivariate Cox regression analyses were performed to study the association between time to TR and prognostic determinants. RESULTS: We included 123 EAF patients (male/female = 58/65) with a median follow-up of 11 years (1626.9 person years). Most were sporadic cases (68.3%), whereas 31.7% reported a family history of epilepsy. At last assessment, 42 patients had achieved TR (34.1%). Of the remaining 81 cases with no TR (65.9%), 37% had been in remission for 1-4 years and 62.9% still had seizures within the past year. The cumulative rates of TR were 26.6%, 35.7%, and 51.6% at 10, 20, and 30 years from inclusion. On multivariate analysis, age at onset > 10 years (hazard ratio [HR] = 3.2, P = .028), auditory aura characterized by distortions only versus simple/complex hallucinations (HR = 2.9, P = .041), and unremarkable scalp electroencephalogram (EEG) versus EEG with focal epileptiform activity (HR = 3.5, P = .041) were associated with TR. SIGNIFICANCE: Our data show a wide prognostic spectrum of EAF, ranging from mild forms with spontaneous remission, to severely refractory epilepsy addressed to surgery. The outcome, less favorable than expected from previous studies, appears to be primarily a function of 3 prognostic negative risk factors: age at onset < 10 years, auditory aura characterized by complex auditory hallucinations, and focal epileptiform abnormalities on scalp EEG. These predictors, easy to collect even at the first visit, may inform both clinicians and patients about the long-term prognosis and aid patient management.

AB - INTRODUCTION: Understanding dental therapy practice across clinical settings is useful for education and service planning. This study assessed if dental therapy service provision varied according to practitioner and workplace characteristics. METHODS: Members of professional associations representing dental therapists (DT) and oral health therapists (OHT) were posted a self-complete survey collecting practitioner and workplace characteristics, together with clinical activity on a self-selected typical day of practice. Differences in service provision according to characteristics were assessed by comparing mean services per patient visit. Negative binomial regression models estimated adjusted ratios (R) of mean services per patient. RESULTS: The response rate was 60.6%. Of practitioners registered as an OHT or a DT, 80.0% (n = 500) were employed in general clinical practice. Nearly one-third of OHT and nearly two-thirds of DT worked in public sector dental services. Patterns of service provision varied significantly according to practice sector and other characteristics. After adjusting for characteristics, relative to private sector, public sector practitioners had higher provision rates of fissure sealants (R = 3.79, 95% confidence interval [95% CI]: 2.84-5.06), restorations (R = 3.78, 95% CI: 2.94-4.86) and deciduous tooth extractions (R = 3.58, 95% CI: 2.60-4.93) per patient visit, and lower provision rates of oral health instruction (R = 0.86, 95% CI: 0.76-0.98), fluoride applications (R = 0.43, 95% CI: 0.33-0.56), scale and cleans (R = 0.39, 95% CI: 0.34-0.45) and periodontal services (R = 0.20, 95% CI: 0.14-0.28) per patient visit. CONCLUSION: Differences in service provision according to sector indicate that OHT and DT adapt to differing patient groups and models of care. Variations may also indicate that barriers to utilising the full scope of practice exist in some settings. PMID- 29464706 TI - A Systems Approach to Biometrics in the Military Domain. AB - Forensic biometrics is the application of forensic science principles to physical and behavioral characteristics. Forensic biometrics is a secondary sub-system in the forensic science "system of systems," which describes forensic science as a sub-system in the larger criminal justice, law enforcement, intelligence, and military system. The purpose of this paper is to discuss biometrics in the military domain and integration into the wider forensic science system of systems. The holistic system thinking methodology was applied to the U.S. biometric system to map it to the system of systems framework. The U.S. biometric system is used as a case study to help guide other countries to develop military biometric systems that are integrated and interoperable at the whole-of government level. The aim is to provide the system of systems framework for agencies to consider for proactive design of biometric systems.

AB - BACKGROUND: To investigate the incidence of heart failure (HF) and ischaemic heart disease (IHD) in different time spans following incident rheumatoid arthritis (RA) and, furthermore, to investigate the impact of IHD on the development of HF and the impact of different treatment era of RA. MATERIALS AND METHODS: This matched cohort study used nationwide, prospectively collected data. From the total Danish population of approximately 5.7 million inhabitants, we identified 51 859 patients (between 1995 and July 2016) with incident RA and a sex- and age-matched cohort from the general population (256 653 persons). RESULTS: The hazard ratio (HR) for HF among RA patients compared with persons from comparison cohort was 2.28 within the first year of index date, 1.39 within the 1-5 years of index date and 1.38 within the 5-10 years of index date. No difference was identified regarding different treatment era of RA. For IHD, the subdistribution hazard ratio (sHR) was 1.93 within the first year of index date, 1.26 within the 1-5 years of index date and 1.31 within the 5-10 years of index date. Coronary revascularization was also more common within the first year after diagnosis of RA. An increased risk of percutaneous coronary intervention and coronary artery bypass grafting within 10 years following the RA diagnosis was observed. HR for new onset of HF in RA without IHD was 1.23, while the HR for new onset of HF in patients with RA and IHD was 2.06. CONCLUSIONS: Rheumatoid arthritis patients had higher rates of HF and IHD throughout the entire observation period compared to the comparison cohort. RA was associated with a larger risk of developing HF. PMID- 29464713 TI - The psychosocial burden of hand eczema: Data from a European dermatological multicentre study. AB - BACKGROUND: The essential physical role, visibility and social importance of the hands place a major psychological burden on patients with hand eczema. OBJECTIVES: The aim of this study was to identify the psychological, social and clinical characteristics of patients with hand eczema, in particular the prevalences of depression, anxiety, suicidal ideation, and comorbidities. MATERIALS AND METHODS: Data on patients with hand eczema were analysed from a large European multicentre study conducted with dermatology outpatients from 13 countries. Groups of patients and controls were compared to analyse the psychological burden of hand eczema. RESULTS: Female patients with hand eczema had higher Hospital Anxiety and Depression Scale (HADS) scores for anxiety (n = 86, median = 7.0) than controls (n = 900, median = 5.0, P = .02), and for depression (median = 4.0) than controls (3.0, P < .001). Patients with high suicidal ideation, with low socioeconomic status and who were widowed or divorced were more likely to fulfil the HADS criteria for anxiety [odds ratio (OR) > 1, P = .038, P < .001, and P < .001, respectively]. The median Dermatology Life Quality Index score was 7.0 (n = 68). DISCUSSION: This study identifies a specific psychological burden experienced by hand eczema patients, highlighting the need for focused psychosocial interventions. Physicians in particular should be aware of the need to identify anxiety and depression in female patients.

PMID- 29464716 TI - Richter transformation driven by Epstein-Barr virus reactivation during therapy related immunosuppression in chronic lymphocytic leukaemia. AB - The increased risk of Richter transformation (RT) in patients with chronic lymphocytic leukaemia (CLL) due to Epstein-Barr virus (EBV) reactivation during immunosuppressive therapy with fludarabine other targeted agents remains controversial. Among 31 RT cases classified as diffuse large B-cell lymphoma (DLBCL), seven (23%) showed EBV expression. In contrast to EBV- tumours, EBV+ DLBCLs derived predominantly from IGVH-hypermutated CLL, and they also showed CLL unrelated IGVH sequences more frequently. Intriguingly, despite having different cellular origins, clonally related and unrelated EBV+ DLBCLs shared a previous history of immunosuppressive chemo-immunotherapy, a non-germinal centre DLBCL phenotype, EBV latency programme type II or III, and very short survival. These data suggested that EBV reactivation during therapy-related immunosuppression can transform either CLL cells or non-tumoural B lymphocytes into EBV+ DLBCL. To investigate this hypothesis, xenogeneic transplantation of blood cells from 31 patients with CLL and monoclonal B-cell lymphocytosis (MBL) was performed in Rag2 /- IL2gammac-/- mice. Remarkably, the recipients' impaired immunosurveillance favoured the spontaneous outgrowth of EBV+ B-cell clones from 95% of CLL and 64% of MBL patients samples, but not from healthy donors. Eventually, these cells generated monoclonal tumours (mostly CLL-unrelated but also CLL-related), recapitulating the principal features of EBV+ DLBCL in patients. Accordingly, clonally related and unrelated EBV+ DLBCL xenografts showed indistinguishable cellular, virological and molecular features, and synergistically responded to combined inhibition of EBV replication with ganciclovir and B-cell receptor signalling with ibrutinib in vivo. Our study underscores the risk of RT driven by EBV in CLL patients receiving immunosuppressive therapies, and provides the scientific rationale for testing ganciclovir and ibrutinib in EBV+ DLBCL.

PMID- 29464718 TI - Technical Note: Feasibility of MRI-based estimation of water-equivalent path length to detect changes in proton range during treatment courses. AB - PURPOSE: To evaluate the feasibility of using on-treatment magnetic resonance imaging (MRI) to detect proton range changes during treatment courses. METHODS: MRI-based virtual computed tomography (vCT) was generated to calculate water equivalent path length (WEPL) at the distal surface of a clinical target volume. T2-weighted MR images with and without fat suppression were processed by thresholding and fuzzy c-mean clustering to assign a bulk HU (Hounsfield Unit) to each segment of fat, water, and air. Bony tissues in vCT were transferred from planning CT via a region-based registration. We validated this method using images from three patients (aged 9, 12, and 17 yr old) with pelvic sarcomas who underwent proton therapy. MRI-based WEPL was evaluated against those of repeat CT (rCT) and cone beam CT (CBCT). RESULTS: The vCT agreed well with the rCT, wherein the use of bulk HU and imperfect bone registration contributed to discrepancies. The 99th percentile error of the MRI-based WEPL was up to 3.3 mm for posterior fields when we compensated the effect of mobile air. The gamma index (2-mm WEPL/2 mm pixel distance) was greater than 99% for those fields. We observed larger errors for anterior fields, which were due to bowel gas movement, mismatched respiratory motion, and differences in patient posture between the vCT and rCT. Applied to multiple on-treatment MRI of a patient, the estimated WEPL demonstrated an underrange trend, which was consistent with the CBCT results and the increased patient body circumference. CONCLUSIONS: The MRI-based vCT produced highly accurate WEPL estimates, demonstrating the potential of using on-treatment MRI for detecting changes in proton ranges. PMID- 29464719 TI - Blood donation history and eligibility assessment in a community-based sample of men who have sex with men. AB - BACKGROUND: In 2016, the US Food and Drug Administration changed the regulation from a permanent deferral from donation for men who have sex with men (MSM) to a 1-year deferral since last sexual contact. It is unknown what proportions of MSM try to donate and if they would be willing to answer individual risk-based questions to assess their current eligibility. STUDY DESIGN AND METHODS: The National HIV Behavioral Surveillance surveys periodically measure human immunodeficiency virus (HIV) prevalence and risk behaviors among MSM using a venue-based, time-location sampling method. In the 2014 cycle, that is, before the policy change, investigators in San Francisco and New Orleans added questions about blood donation. Questions inquired into three domains: donation history, policy awareness, and knowledge about HIV testing of donations. RESULTS: There were 404 and 557 respondents in San Francisco and New Orleans, respectively. Nearly one in three MSM in San Francisco (27.4%) and New Orleans (31.4%) tried to donate after their first MSM contact. A majority (63.1% in San Francisco, 58.8% in New Orleans) somewhat or strongly agreed that they would be willing to be asked detailed questions for donation eligibility assessment. CONCLUSIONS: The proportion of MSM who reported trying to donate was similar in the two cities. However, a substantial proportion did not agree to be asked more detailed risk behavior questions to assess eligibility. In these two geographic locations, prominent regional differences were not evident. PMID- 29464720 TI - The re-emergence of hallucinogenic research.

This article discusses the renewed interest in hallucinogens for such treatment. PMID- 29464721 TI - Physiological response of 10 phytoplankton species exposed to macondo oil and the dispersant, Corexit. AB - Culture experiments were conducted on ten phytoplankton species to examine their biological and physiological responses during exposure to oil and a combination of oil and dispersant. The species tested included a range of taxa typically found in the Gulf of Mexico such as cyanobacteria, chlorophytes, and diatoms. Cultures were exposed to Macondo surrogate oil using the water accommodated fraction (WAF), and dispersed oil using a chemically enhanced WAF (CEWAF) and diluted CEWAF, to replicate conditions following the Deepwater Horizon spill in the Gulf of Mexico. A range of responses were observed, that could broadly class the algae as either "robust" or "sensitive" to oil and/or dispersant exposure. Robust algae were identified as Synechococcus elongatus, Dunaliella tertiolecta, two pennate diatoms Phaeodactylum tricornutum and Navicula sp., and Skeletonema grethae CCMP775, and were largely unaffected by any of the treatments (no changes to growth rate or time spent in lag phase relative to controls). The rest of the phytoplankton, all centric diatoms, exhibited at least some combination of reduced growth rates or increased lag time in response to oil and/or dispersant exposure. Photophysiology did not have a strong treatment effect, with significant inhibition of photosynthetic efficiency (Fv /Fm ) only observed in the CEWAF, if at all. We found that the effects of oil and dispersants on phytoplankton physiology were species-dependent, and not always detrimental. This has significant implications on how oil spills might impact phytoplankton community structure and bloom dynamics in the Gulf of Mexico, which in turn impacts higher trophic levels. PMID- 29464722 TI - Phelipanche aegyptiaca parasitism impairs salinity tolerance in young leaves of tomato. AB - The parasite Phelipanche aegyptiaca infests tomato, a crop plant that is commonly cultivated in semi-arid environments, where tomato may be subject to salt stress. Since the relationship between the two stresses -salinity and parasitism - has been poorly investigated in tomato, the effects of P. aegyptiaca parasitism on tomato growing under moderate salinity were examined. Tomatoes were grown with regular or saline water irrigation (3 and 45 mM Cl- , respectively) in soils infested with P. aegyptiaca. The infested plants accumulated higher levels of sodium and chloride ions in the roots, shoots and leaves (old and young) under both salinity levels vs. non-infected plants. There was a positive linear correlation between P. aegyptiaca biomass and salt accumulation in young tomato leaves, and a negative linear correlation between parasite biomass and the osmotic potential of young tomato leaves. Concentrations of the osmoprotectants proline, myoinositol and sucrose were reduced in infected tomato plants, which impaired the host's osmotic adjustment ability. The sensitivity of P. aegyptiaca to salt stress was manifested as a decrease in biomass. In conclusion, P. aegyptiaca parasitism reduced the salt tolerance of tomato plants by promoting the accumulation of salts from the rhizosphere and impairing the host's osmotic adjustment ability. PMID- 29464723 TI - A unique major histocompatibility complex Class II-binding register correlates with HLA-DR11-associated immunogenicity of the major K blood group antigen. AB - BACKGROUND: Kell is a glycoprotein expressed on red blood cells (RBCs). Its K and k variants contain either Met (K antigen) or Thr (k antigen) at Position 193, respectively. Development of anti-K after K-mismatched antigen exposure via blood transfusions or pregnancy can destroy RBCs, leading to hemolytic transfusion reactions and hemolytic disease of the fetus and newborn. The immunogenicity of overlapping 15-mer Kell peptides with M193 or T193 at every possible position was investigated previously. Interestingly, Peptide W179 to M193, with the polymorphic M193T residue at the peptide's C-terminus, was the most effective at stimulating CD4 T cells from a series of K-immunized women. STUDY DESIGN AND METHODS: This study investigates the basis for HLA restriction of anti-K immune responses. Major histocompatibility complex Class II (MHCII)-binding prediction algorithms and quantitative peptide-MHCII-binding assays were employed to determine the binding registers; anchor residues; and affinities of wild-type, truncated, and sequence-modified K and k peptides. Predictions were generated using Immune Epitope Database and ProPred algorithms. Competitive peptide-MHCII binding assays utilized 12 recombinant HLA-DR proteins, K and k peptides, and high-affinity MHCII-restricted reference peptides. RESULTS: The peptide-MHCII binding assays identified a unique K peptide-binding register (W179-S187) restricted to HLA-DRB1*11:01, in addition to partially overlapping binding registers that included the K/k M193T polymorphic site and that bound promiscuously to multiple HLA-DR proteins. CONCLUSION: Three partially overlapping MHCII-binding motifs for HLA-DRB1*11:01 result in high-avidity K peptide binding, which may contribute to HLA-DR11-restricted immunogenicity associated with the K allele. PMID- 29464724 TI - Exploring and exploiting the boundaries of host specificity using the cereal rust and mildew models. AB - Individual plants encounter a vast number of microbes including bacteria, viruses, fungi and oomycetes through their growth cycle, yet few of these pathogens are able to infect them. Plant species have diverged over millions of years, co-evolving with few specific pathogens. The host boundaries of most pathogen species can be clearly defined. In general, the greater the genetic divergence from the preferred host, the less likely that pathogen would be able to infect that plant species. Co-evolution and divergence also occur within pathogen species, leading to highly specialized subspecies with narrow host ranges. For example, cereal rust and mildew pathogens (Puccinia and Blumeria spp.) display high host specificity as a result of ongoing co-evolution with a narrow range of grass species. In rare cases, however, some plant species are in a transition from host to nonhost or are intermediate hosts (near nonhost). Barley was reported as a useful model for genetic and molecular studies of nonhost resistance due to rare susceptibility to numerous heterologous rust and mildew fungi. This review evaluates host specificity in numerous Puccinia/Blumeria-cereal pathosystems and discusses various approaches for transferring nonhost resistance (NHR) genes between crop species to reduce the impact of important diseases in food production. PMID- 29464725 TI - Gibberellin antagonizes jasmonate-induced defense against Meloidogyne graminicola in rice. AB - Gibberellin (GA) regulates various plant growth and developmental processes, but its role in pathogen attack, and especially nematode-plant interactions, still remains to be elucidated. An in-depth characterization of the role of GA in nematode infection was conducted using mutant lines of rice, chemical inhibitors, and phytohormone measurements. Our results showed that GA influences rice Meloidogyne graminicola interactions in a concentration-dependent manner. Foliar spray of plants with a low concentration of gibberellic acid enhanced nematode infection. Biosynthetic and signaling mutants confirmed the importance of gibberellin for rice susceptibility to M. graminicola infection. Our study also demonstrates that GA signaling suppresses jasmonate (JA)-mediated defense against M. graminicola, and likewise the JA-induced defense against M. graminicola requires SLENDER RICE1 (SLR1)-mediated repression of the GA pathway. In contrast to observations from other plant-pathogen interactions, GA plays a dominant role over JA in determining susceptibility to M. graminicola in rice. This GA-induced nematode susceptibility was largely independent of auxin biosynthesis, but relied on auxin transport. In conclusion, we showed that GA-JA antagonistic crosstalk is at the forefront of the interaction between rice and M. graminicola, and SLR1 plays a central role in the JA-mediated defense response in rice against this nematode.

The objective of this study is to determine the influence of surgery on D-dimer concentration as well as to examine the relation between the magnitude of change and invasiveness of the surgical procedures. STUDY DESIGN: Prospective clinical study. ANIMALS: Forty-five client-owned dogs undergoing elective neutering (n = 15), elective orthopedic (n = 15), or posttraumatic orthopedic (n = 15) surgical procedures. METHODS: Dogs undergoing elective neutering, elective orthopedic, and posttraumatic orthopedic surgical procedures were enrolled. D-dimer concentration, measured immediately prior to, immediately after, and 24 hours after surgery (T0, T1, and T24, respectively), was compared within and among study groups. RESULTS: D-dimer concentration was >250 ng/mL in 8 (18%) dogs at T0, in 9 (20%) at T1, and in 5 (11%) at T24. At T1 and T24, only 2 dogs had a D dimer concentration >500 ng/mL, and it was <750 ng/mL in all dogs. There was no difference in the proportion of increased D-dimer concentration (>250 ng/mL) among the time points (P = 0.29). Median D-dimer concentration did not vary between time points within the groups, except in the neutering group (P = 0.029), in which T1 concentration tended to increase compared with T0 values (161 ng/dL, range 71-727 vs 122 ng/mL, range, 43-353, respectively; P = .065). CONCLUSION: The surgical procedures tested in this study are unlikely to cause a direct increase in D-dimer concentration. CLINICAL SIGNIFICANCE: Any increase in D-dimer concentration after elective neutering, elective orthopedic, and posttraumatic orthopedic surgical procedures should be regarded as clinically important and trigger investigations to detect a hemostatic derangement.

AB - Maize (Zea mays L.) suspension-cultured cells habituated to a cellulose biosynthesis inhibitor 2,6-dichlorobenzonitrile (DCB) have a modified cell wall, in which the reduction in the cellulose content is compensated by a network of highly cross-linked feruloylated arabinoxylans and the deposition of lignin-like polymers. For both arabinoxylan cross-linking and lignin polymerization, class III peroxidases (POXs) have been demonstrated to have a prominent role. For the first time, a comparative study of POX activity and isoforms in control and cellulose-impaired cells has been addressed, also taking into account their cellular distribution in different compartments. Proteins from the spent medium (SM), soluble cellular (SC), ionically (ICW) and covalently bound cell wall protein fractions were assayed for total and specific peroxidase activity by using coniferyl and sinapyl alcohol and ferulic acid as substrates. The isoPOX profile was obtained by isoelectric focusing. POX activity was higher in DCB habituated than in non-habituated cells in all protein fractions at all cell culture stages. For all substrates assayed, SC and ICW fractions showed higher activity at the early log growth phase than at the late log phase. However, the highest POX activity in the spent medium was found at the late log phase. According to the isoPOX profiles, the highest diversity of isoPOXs was detected in the ICW and SM protein fractions. The latter fraction contained isoPOXs with higher activity in DCB-habituated cells. Some of the isoPOXs detected could be involved in cross-linking of arabinoxylans and in the lignin-like polymer formation in DCB-habituated cells. PMID- 29464728 TI - Aluminum oxo-fluoride clusters: A first principle investigation of stability, synthetic considerations, and the interaction with water. AB - The introduction of the so called fluorolytic sol-gel synthesis in 2003 gave access to previously inaccessible aluminum oxo-fluorides, thus to nanoscopic materials and, more importantly, novel catalysts. The intermediate cluster structures synthesized and stabilized by Kemnitz and coworkers have mainly been protected by iso-propoxide groups. However, since catalytic reactions take place in a large variety of media, hydrophilic analogs of those clusters would be of interest. In this manuscript, we present a computational analysis for the fluorination reaction, which represents the second part of fluorolytic sol-gel synthesis, and a theoretical study of the synthesized Al4 F4 (MU4 -O)(MU-Oi Pr)5 [H(Oi Pr)2 ] nanostructure's conversion to its hydroxylated analog Al4 F4 (MU4 O)(MU-OH)5 [H(OH)2 ] utilizing the nudged elastic band method. Furthermore, the role of the fluorine atoms of the cluster in an aqueous medium is evaluated by studying the incremental addition of water molecules to the cluster with and without fluorine atoms. In addition, NMR shifts of clusters exhibiting different substituents are compared. It has been found that the inclusion of an explicit solvent is necessary to capture the magnetic response of the individual cluster atoms in an aqueous solvent correctly.

AB - In this study, the capillary electrophoresis method with ultraviolet detection was established to directly determine amino acids in vinegar, according to the coordination interaction between amino acids (AAs) and copper ions. The online sweeping technique was combined to improve the detection sensitivity. The quality of vinegar was evaluated with AAs as parameters by United Nations Food Agriculture Organization/Word Health Organization AAs model and principal component analysis. Optimum conditions were obtained under 50 mM CuSO4 and adjusted pH 4.40 with 8 mM acetate, 70 s injection time, 22.5 kV separation voltage, and 254 nm detected wavelength. Method validation, indicating good linearity (R2 > 0.9989), precision with an RSD less than 8.0% (n = 5), LOD (0.13 0.25 MUg/mL), LOQ (0.43-0.83 MUg/mL) and recovery (80.5-112.6%). Under the optimal conditions, AAs in vinegar can be directly separated which is propitious for the quality evaluation of vinegar. PMID- 29464730 TI - Demyelination during anti-tumour necrosis factor therapy for psoriasis. AB - Anti-tumour necrosis factor (anti-TNF) therapies have been associated with neurological complications, including in rare cases demyelinating disease. It is currently unknown whether patients who have received more than one immunosuppressive agent or anti-TNF have a greater risk of demyelination. We report the case of a 37-year-old woman with psoriasis who presented with an acute episode of demyelination while on anti-TNF therapy. This case was complicated by the fact that progressive multifocal leukoencephalopathy was considered the likely diagnosis initially and was only definitively excluded by brain biopsy. This case demonstrates the difficulty establishing the correct diagnosis in patients with atypical presentations on immunomodulating therapies. We present this rare case of demyelination in a patient who received multiple immunosuppressive therapies to highlight this challenging clinical situation and discuss management with a literature review.

AB - A computational method which extracts the dominant motions from an ensemble of biomolecular conformations via a correlation analysis of residue-residue contacts is presented. The algorithm first renders the structural information into contact matrices, then constructs the collective modes based on the correlated dynamics of a selected set of dynamic contacts. Associated programs can bridge the results for further visualization using graphics software. The aim of this method is to provide an analysis of conformations of biopolymers from the contact viewpoint. It may assist a systematical uncovering of conformational switching mechanisms existing in proteins and biopolymer systems in general by statistical analysis of simulation snapshots. In contrast to conventional correlation analyses of Cartesian coordinates (such as distance covariance analysis and Cartesian principal component analysis), this program also provides an alternative way to locate essential collective motions in general. Herein, we detail the algorithm in a stepwise manner and comment on the importance of the method as applied to decoding allosteric mechanisms. (c) 2018 Wiley Periodicals, Inc. PMID- 29464734 TI - Prevalence of potential sexual abuse in adolescents and young adults and feasibility of an assessment and management plan used in three research projects. AB - The aims of this study were to examine the feasibility of a protocol to assess for assessment and response to potential sexual abuse (defined as self-report of sexual initiation before age 13) among adolescent and young adult research participants in human papillomavirus (HPV) vaccination screening; determine the proportion of participants whose survey responses indicated potential sexual abuse and assess whether age, gender, race, and recruitment site were associated with potential abuse. We pooled data from three cross-sectional studies of 13-26 year-old women and men (N = 1541) recruited at a Teen Health Center (THC) and Health Department (HD). Using written and electronic documentation, we demonstrated feasibility by the following outcomes: 100% of participants who indicated early sexual initiation were interviewed by the research staff, 100% of assessments were disclosed to participants' primary care clinicians, and no adverse consequences of the interviews or referrals occurred. Potential sexual abuse was identified in 95 participants (6.2%). In multivariable logistic regression, the following factors were independently associated with potential abuse: race (Black vs. White, odds ratio [OR] = 3.0, 95% confidence interval [CI] = 1.6-5.7; other race vs. White, OR = 2.6, 95%CI = 1.0-6.5); and recruitment site (HD vs. THC, OR = 2.1, 95%CI = 1.4-3.3). The standardized protocol to identify, assess and refer youth who may have been sexually abused was feasible and can enable researchers to ensure the safety of study participants.

AB - The notable advances obtained by computational (bio)chemistry provided its widespread use in many areas of science, in particular, in the study of reaction mechanisms. These studies involve a huge number of complex calculations, which are often carried out using the Gaussian suite of programs. The preparation of input files and the analysis of the output files are not easy tasks and often involve laborious and complex steps. Taking this into account, we developed molUP: a VMD plugin that offers a complete set of tools that enhance the preparation of QM and ONIOM (QM/MM, QM/QM, and QM/QM/MM) calculations. The starting structures for these calculations can be imported from different chemical formats. A set of tools is available to help the user to examine or modify any geometry parameter. This includes the definition of layers in ONIOM calculations, choosing fixed atoms during geometry optimizations, the recalculation or adjustment of the atomic charges, performing SCANs or IRC calculations, etc. molUP also extracts the geometries from the output files as well as the energies of each of them. All of these tasks are performed in an interactive GUI that is extremely helpful for the user. MolUP was developed to be easy to handle by inexperienced users, but simultaneously to be a fast and flexible graphical interface to allow the advanced users to take full advantage of this plugin. The program is available, free of charges, for macOS, Linux, and Windows at the PortoBioComp page https://www.fc.up.pt/PortoBioComp/database/doku.php?id=molup. (c) 2018 Wiley Periodicals, Inc. PMID- 29464736 TI - Molecular dynamics coupled with a virtual system for effective conformational sampling. AB - An enhanced conformational sampling method is proposed: virtual-system coupled canonical molecular dynamics (VcMD). Although VcMD enhances sampling along a reaction coordinate, this method is free from estimation of a canonical distribution function along the reaction coordinate. This method introduces a virtual system that does not necessarily obey a physical law. To enhance sampling the virtual system couples with a molecular system to be studied. Resultant snapshots produce a canonical ensemble. This method was applied to a system consisting of two short peptides in an explicit solvent. Conventional molecular dynamics simulation, which is ten times longer than VcMD, was performed along with adaptive umbrella sampling. Free-energy landscapes computed from the three simulations mutually converged well. The VcMD provided quicker association/dissociation motions of peptides than the conventional molecular dynamics did. The VcMD method is applicable to various complicated systems because of its methodological simplicity. (c) 2018 Wiley Periodicals, Inc.

AB - OBJECTIVE: Plasma arginine-vasopressin (AVP) analysis can help in the differential diagnosis of the polyuria-polydipsia syndrome (PPS), even if such investigation is hampered by technical difficulties, conversely to its surrogate copeptin. This study aims to enlarge the existing data on normal copeptin levels in childhood, to evaluate the correlation between copeptin, serum sodium and plasma and urine osmolality, and to assess the utility of the copeptin analysis in the diagnostic work-up of PPS in the paediatric age. PATIENTS AND METHODS: Plasma copeptin levels were evaluated in 53 children without AVP disorders (control population), in 12 hypopituitaric children and in 15 patients with PPS after water deprivation test (WDT). RESULTS: Mean basal copeptin levels were 5.2 +/- 1.56 (range 2.4-8.6 pmol/L) in the control population, 2.61 +/- 0.49 pmol/L in the hypopituitaric children with complete diabetes insipidus (CDI) (P = .04) and 6.21 +/- 1.17 pmol/L in the hypopituitaric patients without DI (P = .02). After WDT, among 15 naive polyuric/polydipsic children, copeptin values greater than 20 pmol/L allowed to identify nephrogenic diabetes insipidus (NDI), concentrations below 2.2 pmol/L complete central DI (CCDI) and between 5 and 20 pmol/L primary polydipsia (PP). Copeptin cut-off level of 3.5 pmol/L distinguished CDI from PP, with a sensitivity and specificity of 75% and 83.3%, respectively. CONCLUSION: Copeptin evaluation holds promises as a diagnostic tool in paediatric PPS; its interpretation might be useful to promptly distinguish NDI, even avoiding the WDT need. PMID- 29464739 TI - Trigger bond analysis of nitroaromatic energetic materials using wiberg bond indices. AB - The identification of trigger bonds, bonds that break to initiate explosive decomposition, using computational methods could help direct the development of novel, "green" and efficient high energy density materials (HEDMs). Comparing bond densities in energetic materials to reference molecules using Wiberg bond indices (WBIs) provides a relative scale for bond activation (%DeltaWBIs) to assign trigger bonds in a set of 63 nitroaromatic conventional energetic molecules. Intramolecular hydrogen bonding interactions enhance contributions of resonance structures that strengthen, or deactivate, the C?NO2 trigger bonds and reduce the sensitivity of nitroaniline-based HEDMs. In contrast, unidirectional hydrogen bonding in nitrophenols strengthens the bond to the hydrogen bond acceptor, but the phenol lone pairs repel and activate an adjacent nitro group. Steric effects, electron withdrawing groups and greater nitro dihedral angles also activate the C?NO2 trigger bonds. %DeltaWBIs indicate that nitro groups within an energetic molecule are not all necessarily equally activated to contribute to initiation. %DeltaWBIs generally correlate well with impact sensitivity, especially for HEDMs with intramolecular hydrogen bonding, and are a better measure of trigger bond strength than bond dissociation energies (BDEs). However, the method is less effective for HEDMs with significant secondary effects in the solid state. Assignment of trigger bonds using %DeltaWBIs could contribute to understanding the effect of intramolecular interactions on energetic properties. (c) 2018 Wiley Periodicals, Inc. PMID- 29464738 TI - Heterozygous aggrecan variants are associated with short stature and brachydactyly: Description of 16 probands and a review of the literature. AB - OBJECTIVE: Mutations in the aggrecan gene (ACAN) have been identified in two autosomal dominant skeletal dysplasias, spondyloepiphyseal dysplasia, Kimberley type (SEDK), and osteochondritis dissecans, as well as in a severe recessive dysplasia, spondyloepimetaphyseal dysplasia, aggrecan type. Next-generation sequencing (NGS) has aided the identification of heterozygous ACAN mutations in individuals with short stature, minor skeletal defects and mild facial dysmorphisms, some of whom have advanced bone age (BA), poor pubertal spurt and early growth cessation as well as precocious osteoarthritis. DESIGN AND METHODS: This study involves clinical and genetic characterization of 16 probands with heterozygous ACAN variants, 14 with short stature and mild skeletal defects (group 1) and two with SEDK (group 2). Subsequently, we reviewed the literature to determine the frequency of the different clinical characteristics in ACAN positive individuals. RESULTS: A total of 16 ACAN variants were located throughout the gene, six pathogenic mutations and 10 variants of unknown significance (VUS). Interestingly, brachydactyly was observed in all probands. Probands from group 1 with a pathogenic mutation tended to be shorter, and 60% had an advanced BA compared to 0% in those with a VUS. A higher incidence of coxa valga was observed in individuals with a VUS (37% vs 0%). Nevertheless, other features were present at similar frequencies. CONCLUSIONS: ACAN should be considered as a candidate gene in patients with short stature and minor skeletal defects, particularly those with brachydactyly, and in patients with spondyloepiphyseal dysplasia. It is also important to note that advanced BA and osteoarticular complications are not obligatory conditions for aggrecanopathies/aggrecan-associated dysplasias. PMID- 29464740 TI - The Current State of Ultrasound Training in Obstetrics and Gynecology Residency Programs. AB - OBJECTIVES: We evaluated the current state of ultrasound training in obstetrics and gynecology (OB-GYN) residency programs across the United States. METHODS: An electronic survey was sent to OB-GYN residency program directors and OB-GYN residents. Responses were obtained in September 2016. Program directors and residents were asked to reflect on their current ultrasound curriculum. RESULTS: A total of 93 program directors and 437 residents responded. Respondents were mostly from university programs located in tertiary centers. Ultrasound curricula varied: 11% of program directors and 23% of residents did not have any ultrasound related didactics; of those who did, 27% of program directors and 40% of residents had it yearly or less. Three-quarters had mandatory ultrasound rotations, and few offered ultrasound electives (program directors, 52%; residents, 28%). Most residents were required to perform ultrasound examinations daily or weekly (98%). Most stated that the main focus of the rotation was OB only. Skill was evaluated mainly subjectively by direct observation. Although most program directors stated that residents were satisfactory/excellent in ultrasound, 22% would not treat patients on the basis of ultrasound examinations performed by their senior residents. Similarly, of all postgraduate year 4 respondents (n = 86), 76% stated that they will require additional training to be able to perform or read ultrasound examinations independently, and 43% would not treat a patient on the basis of their own ultrasound examinations without further confirmation. Residents believed that the biggest obstacle in ultrasound training is lack of dedicated faculty time (41%). CONCLUSIONS: Recognizing the lack of clearly defined milestones in ultrasound training in OB-GYN residency, this study confirms the substantial heterogeneity in curricula between programs, highlighting a need for a standardized ultrasound curriculum. PMID- 29464741 TI - Accuracy of adrenal computed tomography in predicting the unilateral subtype in young patients with hypokalaemia and elevation of aldosterone in primary aldosteronism. AB - CONTEXT: The current Endocrine Society Guideline suggests that patients aged <35 years with marked primary aldosteronism (PA) and unilateral adrenal lesions on adrenal computed tomography (CT) scan may not need adrenal vein sampling (AVS) before proceeding to unilateral adrenalectomy. This suggestion is, however, based on the data from only one report in the literature. OBJECTIVE: We sought to determine the accuracy of CT findings in young PA patients who had unilateral adrenal disease on CT with hypokalaemia and elevation of aldosterone. DESIGN AND PATIENTS: We retrospectively studied 358 PA patients (n = 30, aged <35 years; n = 39, aged 35-40 years; n = 289, aged >=40 years) with hypokalaemia and elevation of aldosterone and unilateral disease on CT who had successful AVS. MAIN OUTCOME MEASURE: Accuracy of CT findings is determined by AVS findings and/or surgical outcomes in patients aged <35 years. RESULTS: Concordance of the diagnosis between CT and AVS was 90% (27/30) in patients aged <35 years, 79% (31/39) in patients aged 35-40 years and 69% (198/289) in those aged >=40 years (trend for P < .01). Surgical benefit was confirmed in three patients aged <35 years and in three patients aged 35-40 years with the available surgical data who had discordance between CT and AVS findings. Collectively, the diagnostic accuracy of CT findings was 100% (30/30) if aged <35 years and 87% (34/39) if aged 35-40 years. CONCLUSION: Primary aldosteronism patients aged <35 years with hypokalaemia and elevation of aldosterone and unilateral disease on adrenal CT could be spared AVS. PMID- 29464742 TI - GdX/UBL4A null mice exhibit mild kyphosis and scoliosis accompanied by dysregulation of osteoblastogenesis and chondrogenesis. AB - GdX, also named ubiquitin-like protein 4A, is a ubiquitin-domain protein characterized by a ubiquitin-like domain that regulates the movement of misfolded proteins from the endoplasmic reticulum membrane to proteasome. However, its function in skeletal biology remains unclear. Here, we report that GdX plays a crucial role in skeletal development as mice lacking GdX exhibit skeletal dysplasias, mild kyphosis, and scoliosis. During embryonic stage, GdX knockout mice display decreased bone mineral density and trabecular bone accompanied by delayed osteogenic formation. GdX knockout mice also have blended spine and small body size. At the molecular level, GdX knockout mice showed perturbed expression of osteogenesis-related genes and cartilage developmental genes, indicative of altered differentiation of mesenchymal cell lineage. Collectively, our results uncovered GdX as a novel regulator in bone development and a potential candidate gene for skeletal dysplasias. PMID- 29464743 TI - Micellar polymerization: Computer simulations by dissipative particle dynamics. AB - Nowadays, micellar polymerization is widely used in different fields of industry and research, including modern living polymerization technique. However, this process has many variables and there is no comprehensive model to describe all features. This research presents simulation methodology which describes key properties of such reactions to take a guide through a variety of their modifications. Dissipative particle dynamics is used in addition to Monte Carlo scheme to simulate initiation, propagation, and termination events. Influence of initiation probability and different termination processes on final conversion and molecular-weight distribution are presented. We demonstrate that prolonged initiation leads to increasing in polymer average molecular weight, and surface termination events play major role in conversion limitation, in comparison with recombination. (c) 2018 Wiley Periodicals, Inc. PMID- 29464744 TI - Primary peri-anal adenocarcinoma of intestinal type - a new proposed entity. AB - AIMS: The currently recognised subtypes of anal canal/peri-anal adenocarcinoma are those arising from low rectal mucosa or columnar cuff, fistula-related tumours and anal gland carcinoma. This report presents two examples of a hitherto undescribed subtype of peri-anal adenocarcinoma with an intestinal phenotype. METHODS AND RESULTS: A 74-year-old man had a peri-anal tumour locally excised, whereas a 73-year-old female underwent an abdominoperineal resection for peri anal Paget's disease with an underlying carcinoma. Neither patient had a history of perineal fistulae, Crohn's disease or previous gastrointestinal neoplasia, and neither showed clinical, radiological or endoscopic evidence of another abdominal or pelvic tumour. Both resection specimens contained adenocarcinoma, which were similar in demonstrating an intestinal morphology and CDX2 immunopositivity. The man has shown a disease-free outcome thus far, but the woman has suffered with nodal and pelvic recurrence within a few months of surgery. CONCLUSIONS: The name 'primary peri-anal adenocarcinoma of intestinal type' is proposed for this previously unrecognised subtype of perineal neoplasia. Awareness of its distinct existence - by recognising its intestinal morphology and immunophenotype while excluding metastasis from the intestinal tract - should help to collate data to determine its specific prognosis and to formulate its best management. PMID- 29464745 TI - Effects of a prevention program for internet addiction among middle school students in South Korea. AB - OBJECTIVES: This study explored the effects of a self-regulatory efficacy improvement program on self-control, self-efficacy, internet addiction, and time spent on the internet among middle school students in South Korea. The program was led by school nurses, and it is integrated self-efficacy and self-regulation promotion strategies based on Bandura's social cognitive theory. DESIGN AND SAMPLE: A quasi-experimental, nonequivalent, control group, pre-posttest design was used. The participants were 79 middle school students. MEASURES: Measurements included the Self-Control Scale, Self-Efficacy Scale, Internet Addiction Proneness Scale, and an assessment of internet addiction. RESULTS: Self-control and self-efficacy significantly increased and internet addiction and time spent on the internet significantly decreased in the intervention group compared with the control group. CONCLUSION: A program led by school nurses that integrated and applied self-efficacy and self-regulation intervention strategies proved effective for prevention of students' internet addiction. PMID- 29464746 TI - Basal cell carcinoma induced by therapeutic radiation for tinea capitis clinicopathological study. AB - AIMS: An increased prevalence of aggressive histological subtypes, such as micronodular and morpheaform, has been seen, irrespective of the clinical course, in basal cell carcinoma (BCC) following irradiation for tinea capitis. The aim of this study was to assess the histopathological features of BCCs among patients irradiated for tinea capitis and correlate them with the clinical course. METHODS AND RESULTS: The medical records and BCC biopsy specimens of individuals who were previously irradiated for tinea capitis were reviewed. Demographic data and clinical characteristics were retrieved. Biopsy specimens were evaluated for histological subtype classification and additional histopathological features. A telephone survey was conducted to assess the clinical behaviour of the tumours. Thirty-one patients (17 male; 14 female) were included. The average age at time of first biopsy was 56 years. The total number of lesions was 185, with 80% of subjects showing multiple lesions. The nodular subtype was the most prevalent, followed by superficial, micronodular and mixed tumours. One-third of the BCCs could be classified as aggressive histologically. Stromal fibroplasia and melanin deposits were common. There was no mortality related to BCC. None of the 17 patients who completed the survey had evidence of local invasiveness or metastases. CONCLUSIONS: BCCs following radiation therapy for tinea capitis show unique histological characteristics related to aggressive behaviour. These aggressive features did not reflect the clinical behaviour in the current cohort. PMID- 29464747 TI - Tarsal attachment devices of the southern green stink bug Nezara viridula (Heteroptera: Pentatomidae). AB - Based on analyses with cryo-scanning and transmission electron microscopy, the present study reports on the morphology and ultrastructure of the attachment structures of the green stinkbug Nezara viridula L. (Heteroptera: Pentatomidae), a cosmopolitan pest of different crops in most areas of the world. In addition, the presence and distribution of large proportions of the elastic protein resilin in these structures was revealed by confocal laser scanning microscopy. The attachment structures of each leg comprise two sclerotised claws, a pair of smooth flexible pulvilli and a hairy adhesive pad located at the ventral side of the basitarsus. No sexual dimorphism is evident. Contact areas of resting individuals on a smooth surface show that N. viridula creates contact to the substrate with the ventral surface of (a) the distal portions of the pulvilli, (b) the setae of the hairy adhesive pad, (c) the two paraempodia representing mechanosensory setae, and (d) the tips of the claws. Each pulvillus is a sac-like structure formed by complex cuticular layers that vary in their structure and resilin content. The dorsal side consists of sclerotised chitinous material, while the ventral cuticle consists mainly of resilin and shows a very thin epicuticle and a thick exocuticle. The setae of the hairy adhesive pad are pointed and socketed. They exhibit a pronounced longitudinal gradient in the material composition, with large proportions of resilin being present in the setal tips. In most of these setae, especially in those of the distal-most part of the pad, also a transverse gradient in the material composition is visible. PMID- 29464748 TI - Prospective randomized study evaluating ultrasound versus fluoroscopy guided sacral InterStim(r) lead placement: A pilot study. AB - OBJECTIVE: To investigate the use of intraoperative ultrasound during stage I InterStim(r) sacral lead placement. METHODS: A total of 40 patients were randomly assigned to undergo InterStim(r) lead placement utilizing fluoroscopy or ultrasound guidance. Patients were blinded for the duration of the study. The surgeon and staff were blinded until after induction of anesthesia. Patients met criteria for refractory overactive bladder, fecal incontinence, or both. The ICIQ OABqol, OABSS, and FIQL validated questionnaires were used pre- and post operatively. Primary endpoint was total fluoroscopy time. Secondary endpoints were total radiation exposure and total number of foramen needle skin punctures. RESULTS: Forty patients were enrolled, twenty in the ultrasound and twenty in the fluoroscopy only arm. Mean age was 60 (SD = 14.4) and mean BMI 32 (SD = 7.2). Twenty-seven patients (67.5%) had urinary symptoms, four (10%) fecal incontinence, and nine (22.5%) had mixed symptoms. Radiation exposure time was reduced by 70.5 s (P = 0.002), radiation exposure was decreased by 42.3 mGy (P = 0.017), and the number of needle skin punctures decreased by 3.6 (P = 0.035) with use of ultrasound. Mean OR time in minutes was 55.5 in ultrasound and 58.2 in fluoroscopy group (P = 0.53). There were no statistically significant differences in questionnaire scores between groups. CONCLUSION: Ultrasound guided placement of foramen needle during Stage I sacral neuromodulation results in reduction of radiation exposure to the patient, surgeon, and operating room staff. Further studies are necessary to determine the learning curve and efficacy of this technique. PMID- 29464749 TI - Intraarticular injection autologous platelet-rich plasma and bone marrow concentrate in a goat osteoarthritis model. AB - To evaluate the effects of intraarticular injections of autologous platelet-rich plasma (PRP) or bone marrow concentrate (BMC) on osteoarthritis (OA), 24 adult goats were equally divided into control (Ctrl), saline (NS), PRP, and BMC groups, and OA was induced by surgery in NS, PRP, and BMC groups. Autologous PRP and BMC were obtained from whole blood and bone marrow aspirates, respectively. The data revealed, platelets were increased in BMC by 1.8-fold, monocytes by 5.6-fold, TGF beta1 by 7.7-fold, and IGF-1 by 3.6-fold (p < 0.05), and platelets were increased in PRP by 2.9-fold, and TGF-beta1 by 3.3-fold (p < 0.05). From the sixth week post-operation, saline, PRP, and BMC were administered by intraarticular injection once every 4 weeks, three consecutive times. After the animals were sacrificed, inflammatory cytokines in the synovial fluid was measured, and bone and cartilage degeneration progression was observed by macroscopy, histology, and immunohistochemistry. Compared with the NS group, the level of inflammatory cytokines was reduced in the PRP and BMC groups (p < 0.05). Histologically, delayed cartilage degeneration and higher levels of extracellular matrix (ECM) were observed in both PRP and BMC treated groups (p < 0.05). Furthermore, the BMC group showed greater cartilage protection and less ECM loss than the PRP group (p < 0.05). In summary, this study showed that intraarticular injection of autologous PRP and BMC has therapeutic efficacy in a goat osteoarthritis model, with the greater benefit in terms of cartilage protection being observed in the BMC-treated group than PRP.

PMID- 29464750 TI - Inhibition of ADAM10 in satellite cells accelerates muscle regeneration following muscle injury. AB - Muscle injury is one of the most common orthopedic and sports disorders. For severe cases, surgical repair may be indicated; however, other than immobilization and the administration of anti-inflammatory drugs there is currently no effective conservative treatment for this condition. Satellite cells (SCs) are muscle-specific stem cells and are indispensable for muscle regeneration after muscle injury. SCs are activated upon muscle injury to proliferate and differentiate into myoblasts, which subsequently fuse into myofibers and regenerate the damaged muscle. We have previously shown that ADAM10, a membrane-anchored proteolytic enzyme, is essential for the maintenance of SC quiescence by activating the Notch signaling pathway in SCs. Because suppression of ADAM10 activity in SCs can activate SC differentiation, we asked whether inactivation of ADAM10 in SCs after muscle injury could enhance muscle regeneration. Using Adam10 conditional knockout mice, in which ADAM10 activity can specifically be suppressed in SCs, we found that partial inactivation of ADAM10 accelerates muscle regeneration after muscle injury. Nearly identical results were obtained by the administration of GI254023X, a selective ADAM10 inhibitor. The findings of the present study thus indicate that transient enhancement of SC differentiation after muscle injury expedites muscle regeneration and that ADAM10 can be a potential molecular target in treating muscle injuries.

PMID- 29464751 TI - Prediction of bladder outcomes after ischemic spinal cord injury: A longitudinal cohort study from the European multicenter study about spinal cord injury. AB - OBJECTIVE: The recovery of bladder function after spinal cord injury (SCI) is of major importance for patients and caregivers. We recently developed prediction models of bladder outcomes (defined as the capacity of storing the urine and emptying completely the bladder) 1 year after a SCI of traumatic etiology and investigated if these models would also be applicable to patients with ischemic SCI. PATIENTS AND METHODS: From the European multicenter study about spinal cord injury (EMSCI), we extracted data of all ischemic SCI patients with available neurological and functional data (according to the International Standards for Neurological Classification of Spinal Cord Injury, ISNCSCI, and Spinal Cord Independence Measure, SCIM) within 40 days and bladder outcomes 1 year after ischemia. The model relies on three predictors: strength of the legs, the presence of sensation in the S3 dermatome, and the part of the SCIM assessing breathing and bladder and bowel control. A simplified model relying on leg strength only was also tested. Bladder outcomes were evaluated according to the score of item six of SCIM. RESULTS: In total 85 patients (56 males (66%), mean age 55 years) were included. Twenty-three patients (27%) showed complete bladder function recovery one year after ischemia. Both models showed a very good predictive power: the area under the receiver operating characteristics curve (aROC) of the two models was 0.825 and 0.822, respectively. CONCLUSIONS: Comparable to acute traumatic SCI, also in ischemic SCI the outcome of full bladder function recovery can be predicted by clinical scores, and prediction models of bladder outcomes may be applicable in clinical trials. PMID- 29464752 TI - Voluntary wheel running attenuates urinary bladder hypersensitivity and dysfunction following neonatal maternal separation in female mice. AB - AIMS: Patients with interstitial cystitis/painful bladder syndrome (IC/PBS) commonly suffer from widespread pain and mood disorder, which has been attributed to improper functioning of the hypothalamic-pituitary-adrenal (HPA) axis. Voluntary exercise has been shown to improve HPA axis function, therefore we are determining whether voluntary wheel running can attenuate urological pain and dysfunction following neonatal maternal separation (NMS) in female mice. METHODS: Mice underwent NMS for 3 h/day from postnatal Day 1-21, were caged with free access to running wheels at 4 weeks of age, and assessed 4 weeks later for bladder sensitivity, micturition, reward behavior, mast cell degranulation, and HPA axis-related in vitro analysis. RESULTS: Increased bladder sensitivity, void frequency, and mast cell degranulation was observed in adult sedentary (-Sed) NMS mice, compared to naive-Sed controls. Sucrose preference was increased in NMS-Sed mice and corticotropin-releasing factor receptor 1 (CRF1 ) and glucocorticoid receptor mRNA levels were significantly reduced in the hippocampus. Exercise normalized bladder sensitivity, micturition output, and increased brain-derived neurotrophic factor (BDNF) mRNA levels in the hippocampus of NMS mice. Mast cell degranulation was also normalized in NMS bladders following exercise. CONCLUSIONS: Voluntary exercise normalized behavioral outcomes resulting from NMS in female mice, increased hippocampal BDNF mRNA levels, and decreased mast cell degranulation in the bladder. Together these results provide novel insight into the efficacy of voluntary exercise to attenuate comorbid outcomes resulting from exposure to early life stress. PMID- 29464754 TI - Development of the duct system during exocrine pancreas differentiation in the grass snake Natrix natrix (Lepidosauria, Serpentes). AB - We analyzed the development of the pancreatic ducts in grass snake Natrix natrix L. embryos with special focus on the three-dimensional (3D)-structure of the duct network, ultrastructural differentiation of ducts with attention to cell types and lumen formation. Our results indicated that the system of ducts in the embryonic pancreas of the grass snake can be divided into extralobular, intralobular, and intercalated ducts, similarly as in other vertebrate species. However, the pattern of branching was different from that in other vertebrates, which was related to the specific topography of the snake's internal organs. The process of duct remodeling in Natrix embryos began when the duct walls started to change from multilayered to single-layered and ended together with tube formation. It began in the dorsal pancreatic bud and proceeded toward the caudal direction. The lumen of pancreatic ducts differentiated by cavitation because a population of centrally located cells was cleared through cell death resembling anoikis. During embryonic development in the pancreatic duct walls of the grass snake four types of cells were present, that is, principal, endocrine, goblet, and basal cells, which is different from other vertebrate species. The principal cells were electron-dense, contained indented nuclei with abundant heterochromatin, microvilli and cilia, and were connected by interdigitations of lateral membranes and junctional complexes. The endocrine cells were electron translucent and some of them included endocrine granules. The goblet cells were filled with large granules with nonhomogeneous, moderately electron-dense material. The basal cells were small, electron-dense, and did not reach the duct lumen. PMID- 29464753 TI - Grade 4 asbestosis does not extend directly from the respiratory bronchiole to the peripheral lung. AB - AIMS: To confirm whether or not grade 4 asbestosis progresses from the respiratory bronchiole to the peripheral lung. METHODS AND RESULTS: We examined retrospectively the autopsy or lobectomy specimens from 31 cases (29 males; mean age 64 years) satisfying the pathological criteria of grade 4 asbestosis. Asbestos bodies (ABs) were quantified in samples of dissolved lung and in tissue preparations on glass slides. Respiratory bronchiolar lesions were graded as 0, 1 and >=2. Grade 4 asbestosis was subdivided into an atelectatic induration (AI) and usual interstitial pneumonia pattern (UIP pattern). Five, 10, and 16 cases had grades 0, 1 or >=2 lesions, respectively, with mean respective numbers of ABs in dissolved lung of 117 000/g dry lung, 468 000/g and 968 000/g; and in specimens on glass slides of seven ABs/cm2 of tissue slice, 34 ABs /cm2 and 195 ABs /cm2 . The differences were significant. Fifteen and 16 cases showed AI and UIP patterns, respectively, with mean respective numbers of ABs in dissolved lung of 1 006 000/g dry lung and 354 000/g, and 186 and 56 ABs/cm2 on glass slides. The differences were significant. AI patterns originated in subpleural lobules or subpleural zonal areas and UIP patterns originated in subpleural, peripheral lobules. CONCLUSIONS: Grade 4 asbestosis does not start in the respiratory bronchiole. The presence of a grade 1 lesion is not required for the diagnosis of grade 4 asbestosis.

AB - A postmarketing surveillance study is ongoing to evaluate nivolumab treatment for Japanese patients with malignant melanoma and accumulate data on all adverse events (AE) and efficacy. In this interim analysis, we evaluated data from approximately 100 Japanese medical institutions obtained from the nivolumab approval date in Japan (4 July 2014) through 3 July 2016. Patients were monitored during the first 12 months of treatment. Nivolumab was administrated by i.v. infusion (2 mg/kg every 3 weeks). A total of 680 and 610 patients were evaluated for safety and efficacy, respectively. The incidences of adverse drug reactions (ADR) and grade 3 or higher ADR were 53.53% and 12.35%, respectively. Predominant ADR included hypothyroidism (11.32%) and abnormal enzyme activity, such as increase of aspartate aminotransferase (7.79%), alanine aminotransferase (6.76%), alkaline phosphatase (6.18%) and gamma-glutamyltransferase (5.44%). Grade 3 or higher ADR of special interest with an incidence of 1% or higher were hepatic function disorder (2.50%), colitis/diarrhea (2.06%) and infusion reaction (1.32%). No cases of encephalitis or venous thromboembolism, other AE of special interest, were observed. The estimated median overall survival was 379 days (95% confidence interval [CI], 290-not reached [NR]) in the overall population, NR (95% CI, 305-NR) for cutaneous melanoma and 340 days (95% CI, 275-NR) for mucosal melanoma. The improvement rate based on the antitumor response at the last evaluation was 22.2% (131/590 patients). No new safety concerns were raised, and serious ADR of special interest were infrequent. Nivolumab showed equivalent efficacy in patients with mucosal melanoma and those with cutaneous melanoma.

AB - AIMS: To evaluate long-term general and urinary quality of life (QOL) and sexual satisfaction in adult neurologic patients undergoing continent cystostomy surgery associated with a bladder enlargement to treat neurogenic lower urinary tract dysfunction. METHODS: Monocentre, retrospective series of adult neurologic patients who underwent continent cystostomy with bladder enlargement and followed up in the long-term. We assessed during follow-up, urinary and renal function and patients filled QOL questionnaires on general QOL, sexuality and urinary (short form Qualiveen) disability. RESULTS: Fifty-three patients were included and followed-up 77 months on average. Rates of patients' satisfaction, stomal and urethral continences were respectively of 98.7% (n = 51), 94.1% (n = 48), and 80.4% (n = 41). Impact of surgery on general QOL and autonomy were strong and positive (respective mean scores of 4.8 and 4.7 on a scale ranging from 1 to 5). Mean overall urinary Qualiveen QOL score was 0.8 (0.09-2.67) indicating a low negative impact of urinary disability on QOL. In patients <45 years, 52.6% (n = 10) reported a moderate to important improvement of their sexuality after surgery. Renal function remained stable during follow-up. CONCLUSION: In the long term, continent cystostomy with bladder enlargement provides great satisfaction to almost most patients. It has a strong positive impact on general and specific urinary QOL, patients' autonomy and urinary continence. In young patients a positive impact on sexuality was also noticed. These encouraging data, that need to be confirmed, constitute interesting information to provide to neurologic patients to help them deciding whether they are willing to undergo continent cystostomy surgery.

AB - AIMS: To perform pelvimetry in nulliparous and primiparous women using 3 Tesla magnetic resonance imaging (3T MRI). METHODS: Twenty-five nulliparous volunteers and 25 primiparous women underwent pelvic 3T MRI within one week after vaginal childbirth in a prospective clinical single-center trial. The pelvimetric parameters interspinous distance (ISD), intertuberous distance (ITD), sagittal outlet (SO), obstetric conjugate (OC), and coccygeal curved length (CCL) were adapted from anthropometric measurements as well as from sonographic and computed tomography-based pelvimetry performed on high-resolution T2-weighted images. We compared the results of the two study groups to one another, recent literature and postpartum-diagnosed levator ani muscle (LAM) injuries. RESULTS: The mean values for primipara/nullipara were ISD 107 +/- 8.3/105 +/- 8.4 mm, ITD 119.8 +/- 10.2/118.4 +/- 13.1 mm, OC 129.4 +/- 10/130.8 +/- 6.9 mm, SO 114.3 +/- 7.8/112.5 +/- 8.9 mm, and CCL 37.3 +/- 7.4/39 +/- 8 mm. Significant differences (P < 0.05) were found between the results for OC, SO, and CCL (primipara) and ISD, ITD and OC (nullipara) and the values in the literature. No significant difference in pelvimetric values was found between the groups. A significant correlation was found between the pelvimetric parameters and five types of LAM injuries. CONCLUSIONS: Two-dimensional 3T MRI combines high-resolution images with objective pelvimetric measurements applicable in a postpartum setting. Our results provide a good foundation for further MRI-based studies evaluating the bony pelvis and its relation to LAM injuries during vaginal childbirth. PMID- 29464758 TI - A genomic and clinicopathological study of non-small-cell lung cancers with discordant ROS1 gene status by fluorescence in-situ hybridisation and immunohistochemical analysis. AB - AIMS: ROS1 immunohistochemistry (IHC) using D4D6 antibody is a useful tool for screening patients with non-small-cell lung cancer (NSCLC) who may be suitable for targeted therapy. Many studies and our data have identified cases that express the ROS1 protein strongly but are negative for ROS1 by fluorescence in situ hybridisation (FISH). The present study investigated the driver mutation and clinicopathological characteristics of 26 discordant cases (ROS1 IHC-positive but FISH-negative) to find new clues for distinguishing real ROS1-rearranged cases. METHODS AND RESULTS: Tumours from 26 discordant cases were analysed for clinicopathological characteristics, mutations in EGFR, KRAS, ERBB2, BRAF and PIK3CA; fusions in ALK and RET; and amplifications in MET, ERBB2 and ROS1. ROS1 rearranged NSCLCs were significantly more likely to be found in younger patients and at an advanced stage; they showed cribriform features, extracellular mucus and psammoma bodies, whereas ROS1-discordant cases were found in older patients at a relatively early tumour-node-metastasis (TNM) stage and showed a lepidic growth pattern (all P < 0.001). Most ROS1-rearranged NSCLCs had no concurrent mutation, whereas 73% of discordant cases harboured genetic aberrations, including EGFR and ERBB2. Compared with general lung adenocarcinomas, ERBB-2 abnormality was disproportionately high in ROS1-discordant cases. Moreover, we optimised the scoring criteria for ROS1 IHC as 'H score > 150 and no concurrent mutations'; the specificity was then increased to 81.6%. CONCLUSIONS: Compared with ROS1-rearranged cases, ROS1-discordant patients showed distinct clinical and morphological features and often harboured another oncogenic driver alteration. The use of optimised screening criteria will increase the specificity of ROS1 antibody.

AB - AIMS: Historically, urine has been viewed primarily as a waste product with little biological role in the overall health of an individual. Increasingly, data suggest that urine plays a role in human health beyond waste excretion. For example, urine might act as an irritant and contribute to symptoms through interaction with-and potential compromise of-the urothelium. METHODS: To explore the concept that urine may be a vehicle for agents with potential or occult bioactivity and to discuss existing evidence and novel research questions that may yield insight into such a role, the National Institute of Diabetes and Digestive and Kidney Disease invited experts in the fields of comparative evolutionary physiology, basic science, nephrology, urology, pediatrics, metabolomics, and proteomics (among others) to a Urinology Think Tank meeting on February 9, 2015. RESULTS: This report reflects ideas that evolved from this meeting and current literature, including the concept of urine quality, the biological, chemical, and physical characteristics of urine, including the microbiota, cells, exosomes, pH, metabolites, proteins, and specific gravity (among others). Additionally, the manuscript presents speculative, and hopefully testable, ideas about the functional roles of urine constituents in health and disease. CONCLUSION: Moving forward, there are several questions that need further understanding and pursuit. There were suggestions to consider actively using various animal models and their biological specimens to elaborate on basic mechanistic information regarding human bladder dysfunction. PMID- 29464761 TI - Evolution of facial innervation in anomodont therapsids (Synapsida): Insights from X-ray computerized microtomography. AB - Anomodontia was the most successful herbivorous clade of the mammalian stem lineage (non-mammalian synapsids) during the late Permian and Early Triassic. Among anomodonts, Dicynodontia stands apart because of the presence of an osseous beak that shows evidence of the insertion of a cornified sheath, the ramphotheca. In this study, fourteen anomodont specimens were microCT-scanned and their trigeminal canals reconstructed digitally to understand the origin and evolution of trigeminal nerve innervation of the ramphotheca. We show that the pattern of innervation of the anomodont "beak" is more similar to that in chelonians (the nasopalatine branch is enlarged and innervates the premaxillary part of the ramphotheca) than in birds (where the nasopalatine and maxillary branches play minor roles). The nasopalatine branch is noticeably enlarged in the beak-less basal anomodont Patranomodon, suggesting that this could be an anomodont or chainosaur synapomorphy. Our analyses suggest that the presence or absence of tusks and postcanine teeth are often accompanied by corresponding variations of the rami innervating the caniniform process and the alveolar region, respectively. The degree of ossification of the canal for the nasal ramus of the ophthalmic branch also appears to correlate with the presence of a nasal boss. The nasopalatine canal is absent from the premaxilla in the Bidentalia as they uniquely show a large plexus formed by the internal nasal branch of the maxillary canal instead. The elongated shape of this plexus in Lystrosaurus supports the hypothesis that the rostrum evolved as an elongation of the subnarial region of the snout. Finally, the atrophied and variable aspect of the trigeminal canals in Myosaurus supports the hypothesis that this genus had a reduced upper ramphotheca. PMID- 29464762 TI - KPR-2579, a novel TRPM8 antagonist, inhibits acetic acid-induced bladder afferent hyperactivity in rats. AB - AIMS: Transient receptor potential melastatin 8 (TRPM8) is proposed to be a promising therapeutic target for hypersensitive bladder disorders. We examined the effects of KPR-2579, a novel selective TRPM8 antagonist, on body temperature and on mechanosensitive bladder single-unit afferent activities (SAAs) provoked by intravesical acetic acid (AA) instillation in rats. METHODS: Female Sprague Dawley rats were used. Effects of cumulative intravenous (i.v.) administrations of KPR-2579 (0.03-1 mg/kg) on deep body temperature were investigated (N = 18). In separate animals, effects of bolus administration of KPR-2579 (0.03 or 0.3 mg/kg, i.v.) on bladder hyperactivity induced by intravesical instillation of 0.1% AA were investigated using cystometry (N = 57) in a conscious free-moving condition or urethane-anesthetized condition, and SAA measurements (N = 41) were performed in a urethane-anesthetized condition. RESULTS: KPR-2579 at any doses tested did not affect body temperature. In cystometry measurements, a high dose (0.3 mg/kg) of KPR-2579 counteracted the shortened intercontraction interval provoked by AA instillation. In SAA measurements, 48 single afferent fibers (n = 24 in each fiber) were isolated. AA instillations significantly increased the SAAs of C fibers, but not of Adelta fibers, in the presence of KPR-2579's vehicle and a low dose (0.03 mg/kg) of KPR-2579. Pretreatment with a high dose (0.3 mg/kg) of KPR-2579 significantly inhibited the AA-induced activation of C-fiber SAAs. CONCLUSION: The present results suggest that TRPM8 channels play a role in the AA-induced pathological activation of mechanosensitive bladder C fibers in rats. KRP-2579 may be a promising drug for hypersensitive bladder disorders. PMID- 29464763 TI - Promising therapeutic option for cutaneous plasmacytosis: 308-nm excimer lamp. PMID- 29464764 TI - A pilot feasibility study of treating overactive bladder patients with percutaneous saphenous nerve stimulation. AB - AIMS: Effective long-term treatment of overactive bladder (OAB) remains a significant clinical challenge. We present our initial experience with a new bladder neuromodulation method that electrically targets the saphenous nerve (SAFN). METHODS: A total of 18 OAB patients (female, 55-84 years) were provided with percutaneous SAFN stimulation. The SAFN was targeted with a needle electrode inserted below the medial condyle of the tibia. Activation of the SAFN was confirmed by the patient's perception of paresthesia radiating down the leg. Electrical stimulation was applied for 30 min and subsequently repeated weekly for 3 months. The effects of stimulation were assessed by a 4-day bladder diary and quality-of-life questionaire (OAB-q). RESULTS: Percutaneous SAFN stimulation was confirmed in all 16 patients who completed the study, and no adverse events were reported. Positive response to SAFN stimulation was achieved in 87.5% (14 of 16) of patients, as determined by either a minimum 50% reduction in bladder symptoms or a minimum 10 point increase in the HRQL total score. CONCLUSIONS: Electrical activation of the SAFN was consistently achieved using anatomical landmarks and patient feedback. The procedure was well tolerated and, based on our small cohort of patients, appears efficacious, and safe. This pilot study provides early feasibility data that points to a promising new intervention for treating OAB. PMID- 29464765 TI - Delay of alternative antiviral therapy and poor outcomes of acyclovir-resistant herpes simplex virus infections in recipients of allogeneic stem cell transplant a retrospective study. AB - Acyclovir is commonly used to prevent and treat herpes simplex virus (HSV) reactivation after hematopoietic cell transplant (HCT), and only few reports have been published on acyclovir-resistant HSV in HCT recipients. We reviewed the medical records of patients with a microbiologic diagnosis of acyclovir-resistant HSV by plaque reduction test who received an HCT from 2002 through 2014. A total of 4 028 HCTs were performed during the study period, and 18 of the recipients met the diagnostic criteria for acyclovir-resistant HSV. All cases had undergone allogeneic HCTs. Most patients were in the pre-engraftment period or on systemic corticosteroid therapy for graft-versus-host disease (GVHD). The median time between diagnosis and susceptibility testing was 15 days, and antiviral therapy was changed at a median of 27 days. Patients required prolonged therapy (~80 days), and many had serious complications including renal failure and hospitalization. In conclusion, acyclovir-resistant HSV infection is more likely during the period of profound deficit in T-cell-mediated immunity and is associated with significant morbidities. Higher doses of acyclovir prophylaxis might be needed for patients with history of HSV during pre-engraftment or GVHD treatment. In patients who do not respond or progress after 1 week of acyclovir therapy, testing for drug-resistant HSV, and early switch to an alternative antiviral should be considered. PMID- 29464767 TI - Afterword: materialities, care, 'ordinary affects', power and politics. AB - In this paper I explore how the papers in this volume offer ways of thinking about materialities of care in terms of political ecologies, including hierarchies of value as well as assemblages, in which strategic agendas are made present in everyday practices, with profound and ordinary affects, as well as effects. I show how power can work through the association of multiple and heterogeneous materials and social processes to create 'thresholds', as spaces through which people must pass in order to be included as patients, and which circulate specific imaginaries over what counts as an appropriate need. I go on to suggest how some material practices are made mundane and immaterial, that is inconsequential, so that by drawing attention to their importance in how care is done (or not done) the papers help disrupt the commonplace production and reproduction of the 'neglected things' (Puig de la Bellacasa ) of healthcare environments, and by so doing help reimagine what is important for occasions to actually be caring. I then shift to thinking about a sensibility, one that is highly valued in this collection of articles, that helps illuminate different imaginaries of care to those that dominate healthcare environments, an approach that I have called elsewhere 'relational extension', and in the example I offer here show how shifts in extension as a form of motility disrupts stabilities and their reproduction, to accomplish different forms of world-making. PMID- 29464768 TI - Dressing disrupted: negotiating care through the materiality of dress in the context of dementia. AB - This paper explores how the materiality of dress mediates and shapes practices of care in the context of dementia. Earlier research called for an approach to conceptualising care that recognised the role played by everyday artefacts. We extend this to a consideration of dress and dressing the body in relation to people with dementia that involves the direct manipulation of material objects, as well as the materiality of bodies. The paper draws on an ESRC funded study Dementia and Dress, which examined experiences of dress for people with dementia, families and care-workers using ethnographic and qualitative methods. Our analysis explores the process of dressing the body, the physicality of guiding and manipulating bodies into clothing, dealing with fabrics and bodies which 'act back' and are resistant to the process of dressing. We consider how the materiality of clothing can constrain or enable practices of care, exploring tensions between garments that support ease of dressing and those that sustain identity. Examining negotiations around dress also reveals tensions between competing 'logics' of care (Mol ). PMID- 29464769 TI - Becoming at home in residential care for older people: a material culture perspective. AB - Residential homes encourage new residents to bring belongings with them, so that they can personalise their room and 'feel at home'. Existing literature on material culture in residential homes views objects as symbols and repositories of home and identity, which can facilitate a sense of belonging in residents through their display in residents' rooms. I suggest that this both misunderstands the processual and fluid nature of home and identity, and conceptualises objects as essentially passive. This article uses ethnographic data and theories of practice and relationality to argue that rather than the meaning of home being inherent in objects, or felt subjectively by residents, meaning is generated through ongoing, everyday interactions between the two. I show that residents became at home by acquiring new things -as well as displaying existing possessions - and also through interacting with mundane objects in everyday social and relational practices such as cleaning and hosting. I conclude that being at home in older people's residential homes need not be so different from being at home at other stages of the life course and in other settings. This challenges conceptualisations of older people's homes - and older age itself - as somehow unknowable and unfamiliar. PMID- 29464766 TI - Systemic and transdermal melatonin administration prevents neuropathology in response to perinatal asphyxia in newborn lambs. AB - Perinatal asphyxia remains a principal cause of infant mortality and long-term neurological morbidity, particularly in low-resource countries. No neuroprotective interventions are currently available. Melatonin (MLT), a potent antioxidant, anti-inflammatory and antiapoptotic agent, offers promise as an intravenous (IV) or transdermal therapy to protect the brain. We aimed to determine the effect of melatonin (IV or transdermal patch) on neuropathology in a lamb model of perinatal asphyxia. Asphyxia was induced in newborn lambs via umbilical cord occlusion at birth. Animals were randomly allocated to melatonin commencing 30 minutes after birth (60 mg in 24 hours; IV or transdermal patch). Brain magnetic resonance spectroscopy (MRS) was undertaken at 12 and 72 hours. Animals (control n = 9; control+MLT n = 6; asphyxia n = 16; asphyxia+MLT [IV n = 14; patch n = 4]) were euthanised at 72 hours, and cerebrospinal fluid (CSF) and brains were collected for analysis. Asphyxia resulted in severe acidosis (pH 6.9 +/- 0.0; lactate 9 +/- 2 mmol/L) and altered determinants of encephalopathy. MRS lactate:N-acetyl aspartate ratio was 2.5-fold higher in asphyxia lambs compared with controls at 12 hours and 3-fold higher at 72 hours (P < .05). Melatonin prevented this rise (3.5-fold reduced vs asphyxia; P = .02). Asphyxia significantly increased brain white and grey matter apoptotic cell death (activated caspase-3), lipid peroxidation (4HNE) and neuroinflammation (IBA-1). These changes were significantly mitigated by both IV and patch melatonin. Systemic or transdermal neonatal melatonin administration significantly reduces the neuropathology and encephalopathy signs associated with perinatal asphyxia. A simple melatonin patch, administered soon after birth, may improve outcome in infants affected by asphyxia, especially in low-resource settings. PMID- 29464770 TI - Placing care: embodying architecture in hospital clinics for immigrant and refugee patients. AB - This article is part of a hospital ethnography that investigates healthcare architecture as an aspect of an increasingly large, complex, and urgent global health issue: caring for refugees and other immigrants. It argues that hospitals are nodes in transnational social networks of immigrant and refugee patients that form assemblages of human and non-human objects. These assemblages co-produce place-specific hospital care in different hospital spaces. Place-specific tensions and power dynamics arise when refugees and immigrants come into contact with these biomedical spaces. The argument is developed by analysing waiting rooms and exam rooms in two outpatient clinics in one US hospital. The article draws its analysis from 9 months of fieldwork in 2012 that included following 69 adult immigrant and refugee patients and observing their encounters with interpreters and clinic staff. Its inclusion of a transnational dimension for understanding place-specific hospital care adds conceptual and empirical depth to the study of how place matters in 21st century hospitals. PMID- 29464771 TI - Materialities of mundane care and the art of holding one's own. AB - The focus of this special issue is on how everyday or mundane materialities actively mediate health and care practices. This article extends this concern with the mundane to care itself and explores how specific materialities, such as shared spaces and everyday objects, not only mediate mundane care but enable it to happen. Our focus is on mundane help in the context of ill health, between people who are not immediate family, such as neighbours, acquaintances and others with whom we interact in our daily lives. Drawing on recent empirical studies of low-level support in two different parts of the UK, we show how the materialities of care can mediate the affective risks associated with receiving such help. Specifically, we investigate how materialities help people to balance the expression of their vulnerability with a need to retain their dignity, a practice referred to as 'holding one's own'. In doing so, we argue that materialities are not just the conduits for care - what care passes through - or things that mediate care. We suggest instead that materialities are part of how relationships of mundane care are constituted and maintained. PMID- 29464772 TI - The art and nature of health: a study of therapeutic practice in museums. AB - Drawing on ethnographic fieldwork and interviews at a major metropolitan art museum and botanic garden, this article considers the practical accomplishment of American museums' 'health turn' by tracing how museum staff develop therapeutic programmes for visitors with disabilities. In doing so, it considers one of medical sociology's fundamental theoretical questions - how ideologies of health order social life - in an unconventional empirical setting. Acknowledging contemporary arguments for both the relative merits and unintended consequences of this policy trend, I focus instead on the particular institutional arrangements, professional norms, and material cultures of art and nature that shape museums' therapeutic work, so as to reveal its effects. Data reveals ideological similarities, but practical differences, between museological and medical understandings of wellness. Extending a 'medical sociology of practice' to new contexts ultimately foregrounds the contingencies, and diversity, of therapeutic mechanisms and meanings, thereby broadening sociological research on healing and healthism. PMID- 29464773 TI - Thinking with care infrastructures: people, devices and the home in home blood pressure monitoring. AB - The growing consumer market in health monitoring devices means that technologies that were once the preserve of the clinic are moving into spaces such as homes and workplaces. We consider how one such device, blood pressure monitors, comes to be integrated into everyday life. We pursue the concept of 'care infrastructure', drawing on recent scholarship in STS and medical sociology, to illuminate the work and range of people, things and spaces involved in self monitoring. Drawing on a UK study involving observations and interviews with 31 people who have used a consumer blood pressure monitor, we apply the concept beyond chronic illness, to practices involving consumer devices - and develop a critical account of its value. We conclude that the care infrastructure concept is useful to highlight the socio-material arrangements involved in self monitoring, showing that even for ostensibly personal devices, monitoring may be a shared practice that expresses care for self and for others. The concept also helps draw attention to links between different objects and spaces that are integral to the practice, beyond the device alone. Care infrastructure draws attention to the material, but ensures that analytic attention engages with both material and social elements of practice and their connections. PMID- 29464774 TI - Family food practices: relationships, materiality and the everyday at the end of life. AB - This article draws on data from a research project that combined participant observation with in-depth interviews to explore family relationships and experiences of everyday life during life-threatening illness. In it I suggest that death has often been theorised in ways that make its 'mundane' practices less discernible. As a means to foreground the everyday, and to demonstrate its importance to the study of dying, this article explores the (re)negotiation of food and eating in families facing the end of life. Three themes that emerged from the study's broader focus on family life are discussed: 'food talk' and making sense of illness; food, family and identity; and food 'fights'. Together the findings illustrate the material, social and symbolic ways in which food acts relationally in the context of dying, extending conceptual work on materiality in death studies in novel directions. The article also contributes new empirical insights to a limited sociological literature on food, families and terminal illness, building on work that theorises the entanglements of materiality, food, bodies and care. The article concludes by highlighting the analytical value of everyday materialities such as food practices for future research on dying as a relational experience. PMID- 29464775 TI - Conceptualising 'materialities of care': making visible mundane material culture in health and social care contexts. AB - 'Materialities of care' is outlined as a heuristic device for making visible the mundane and often unnoticed aspects of material culture within health and social care contexts, and exploring interrelations between materials and care in practice. Three analytic strands inherent to the concept are delineated: spatialities of care, temporalities of care and practices of care. These interconnecting themes span the articles in this special issue. The articles explore material practice across a range of clinical and non-clinical spaces, including hospitals, hospices, care homes, museums, domestic spaces, and community spaces such as shops and tenement stairwells. The collection addresses fleeting moments of care, as well as choreographed routines that order bodies and materials. Throughout there is a focus on practice, and relations between materials and care as ongoing, emergent and processual. We conclude by reflecting on methodological approaches for examining 'materialities of care', and offer some thoughts as to how this analytic approach might be applied to future research within the sociology of health and illness. PMID- 29464776 TI - Private finance initiative hospital architecture: towards a political economy of the Royal Liverpool University Hospital. AB - Sociological analysis has done much to illuminate the architectural contexts in which social life takes place. Research on care environments suggests that the built environment should not be understood as a passive backdrop to healthcare, but rather that care is conditioned by the architecture in which it happens. This article argues for the importance of going beyond the hospital walls to include the politics that underwrite the design and construction of hospital buildings. The article assesses the case of the yet-to-be-realised Liverpool Royal University Hospital, and the private finance initiative (PFI) funding that underpins the scheme, which is suggested as a salient 'external' context for understanding architecture's role in the provision of healthcare of many kinds for many years to come. PFI has major implications for democratic accountability and local economy, as well as for the architecture of the hospital as a site of care. Critical studies can illuminate these paradoxically visible-but-opaque hospital spaces by going beyond that which is immediately empirically evident, so as to reveal the ways in which hospital architecture is conditioned by political and economic forces. PMID- 29464777 TI - Associations between fatigue, physical activity, and QoL in patients with myeloproliferative neoplasms. AB - BACKGROUND: Patients with Philadelphia chromosome-negative Myeloproliferative Neoplasms (MPNs) report fatigue as the most common symptom and contributing significantly to reduction in their quality of life (QoL). Targeted non pharmacological intervention to increase levels of physical activity is suggested as a fatigue-reducing and QoL-enhancing intervention in MPN patients. The interrelationship between physical activity, fatigue, and QoL has, to our knowledge, never been reported. METHODS: We analyzed data from 1807 MPN patients. The primary analysis included a multiple regression model allowing fatigue to mediate the relationship between physical activity and QoL. RESULTS: We herein report the first and the largest study of patients with MPNs, in whom we have investigated the interrelationship between fatigue, physical activity, and QoL. Sedentary patients were more likely to report fatigue compared to highly active patients. There was a negative association between fatigue and QoL, and there was a positive association between physical activity and QoL. There was no interaction between fatigue and physical activity in the association with QoL. CONCLUSION: We found positive associations between level of physical activity and QoL, independently of fatigue being present. More research is needed before physical activity can be introduced as a targeted intervention to reduce fatigue and increase QoL in the management of patients.

PMID- 29464778 TI - Expression of 14-3-3 sigma and eta proteins is unrelated to survival in metastatic high-grade serous carcinoma. AB - The objective of this study was to analyze the expression and clinical role of 14 3-3 family proteins in high-grade serous carcinoma (HGSC). Protein expression of 14-3-3 sigma (14-3-3sigma) and 14-3-3 eta (14-3-3eta) by immunohistochemistry was studied in 298 HGSC specimens (249 peritoneal, 49 pleural) and was analyzed for association with clinicopathologic parameters, chemoresponse and survival. The 14 3-3sigma protein was diffusely (>75% of cells) expressed in 100% of carcinomas in analysis of a pilot series and was therefore not further analyzed. The 14-3-3eta protein was expressed to a variable extent in 260/298 (87%) effusions. Higher 14 3-3eta protein expression was significantly related to higher CA 125 levels at diagnosis (p = 0.004), but was unrelated to other clinicopathologic parameters, chemoresponse or survival. Analysis of the association between 14-3-3eta and previously studied proteins regulating mitosis showed positive association with class III beta-tubulin expression (p = 0.025). The present study documents frequent expression of 14-3-3sigma and 14-3-3eta in HGSC effusions, but does not support a role for these proteins as prognostic markers or predictors of chemotherapy response in metastatic HGSC.

PMID- 29464781 TI - Physicochemical Stability and Sterility of Standard Parenteral Nutrition Solutions and Simulated Y-Site Admixtures for Neonates. AB - BACKGROUND: Parenteral nutrition (PN) is frequently needed in neonatal intensive care. The use of standard PN has emerged as an easy-to-prescribe approach that allows one to have on-site, ready-to-use PN. The aim of this study was to test the physicochemical stability and sterility of 2 specific PN solutions as well as simulate Y-site compatibility with lipid injectable emulsions (ILE). METHODS: Our study considered 2 standard ILE-free PN solutions according to neonatal weight. These solutions were prepared in duplicate and stored at 4 degrees C. The following physicochemical parameters were tested: visual alterations, turbidity, pH, osmolarity, and calcium concentration. Sterility was assessed by means of agar blood culture and glucose concentration determination. In addition, we assessed the stability of simulated Y-site admixtures. For each standard ILE-free PN solution, 2 3-in-1 PN admixtures were designed, considering extreme values of fluid requirements (50 and 150 ml/kg/d) and a fat supply of 2 g/kg/24 h. The physicochemical parameters tested were phase separation and fat mean droplet size distribution. RESULTS: No alterations were detected by visual inspection. Calcium concentrations, turbidity, pH, and osmolarity values remained stable in all the determinations. All agar blood cultures were negative and glucose concentration was constant over time. Physical stability of simulated Y-site admixtures was considered acceptable as mean droplet size distribution remained below 500 nm in all the emulsions. CONCLUSION: The 2 tested standard ILE-free PN solutions for neonates are physicochemically stable and sterile for 31 days under refrigeration (4 degrees C). These solutions are also stable in case of Y-site administration with ILE at the conditions tested.

AB - The participation of peripheral peptides in the processes regulating the food intake (energy homeostasis) at the central nervous system level remains unclear. This study focuses on the role of obestatin in neuronal activity within the hypothalamic appetite-regulating network in ruminants. The animals (n = 28) were randomly divided into two groups. The sheep in the control group received intracerebroventricular infusions of the Ringer-Locke solution, and the sheep in obestatin group were infused with obestatin (diluted in the Ringer-Locke solution) at 25 MUg per 120 MUl/hr. The series of four 1-hr infusions on 3 consecutive days were performed, and immediately after the experiment, the sheep were decapitated. Selected brain regions were fixed in situ for further immunohistochemical analysis, while the remaining ones were frozen for real-time RT-qPCR analysis. Obestatin infusion elicited changes in the neuropeptide Y (NPY) neuronal network in the hypothalamus. The results obtained show that exogenous obestatin evoked an increase in npy and agrpmRNA expression in the mediobasal hypothalamus (MBH), while the immunoreactivity for NPY was decreased in the arcuate and periventricular nuclei. The increase in cart and pomcmRNA expression in the MBH was also observed. Moreover, increased levels of gpr39 receptor and npy receptor 1 mRNA expression were evident in obestatin-infused sheep. Based on these results, it can be concluded that obestatin plays a role in the modulation of appetite-regulating network at the central level in sheep. The results obtained suggest that the underlying mechanism may involve the modification of the activity of NPY/AgRP and CART/alpha-MSH neurons in the arcuate nucleus.

AB - INTRODUCTION: To study the evolution of type of presenting symptoms after mid urethral sling (MUS) placement relative to the interval between placement and subsequent synthetic sling removal (SSR) for complication(s). METHODS: An IRB approved, prospectively maintained database of women who underwent SSR was retrospectively reviewed for demographics, interval between MUS placement and SSR, history of chronic pain syndromes and recurrent urinary tract infections (RUTI), anti-incontinence and prolapse repairs, and MUS-related symptoms at presentation, including storage dysfunction, voiding dysfunction, RUTI, vaginal pain, non-vaginal pain, mesh exposure, and urinary incontinence (UI). Comparisons were made between patient groups divided into 2 and 4-year intervals to test the hypothesis that there would be higher rates of mesh exposure, pain and/or dyspareunia earlier, but higher rates of RUTI and UI in later groups. RESULTS: Between 2005-2017, 278/435 women met study criteria. Overall, mean number of presenting symptoms per patient was 3.8 +/- 1.4 and increased significantly in relation to time since MUS placement (P < 0.01). There was a significant difference between number of patients presenting with RUTI (P = 0.01), vaginal pain (P = 0.03), and UI (P = 0.03) between the 2-year groups and a significant difference between number of patients presenting with RUTI (P < 0.01), non vaginal pain (P = 0.01) and vaginal pain (P = 0.05) between the 4-year groups. CONCLUSIONS: In our tertiary care center, women with MUS-related complications presented with multiple symptoms that increased in number over time, with a higher rate of pain complaints in earlier groups but a higher rate of RUTI and UI in later groups. PMID- 29464784 TI - Total nasal reconstruction with 3D custom made porous titanium prosthesis and free thoracodorsal artery perforator flap: A case report. AB - Total nasal reconstruction is a challenging surgical procedure which usually involves a free flap, forehead flap, and cartilage grafts. In certain failure situations where patients do not accept the idea of anaplastology, possibilities become very limited. We report the case of a patient who underwent several reconstruction steps with multiple failures including free and local flaps and cartilage harvests which showed recurrent episodes of necrosis and infection leading to melting and collapse of reconstructed structures. Furthermore, the patient did not want any anaplastological rehabilitation. We proposed to the patient an innovative method that consists to print a three-dimensional custom made porous titanium prosthesis, based on the original shape of his nose, to replace the cartilage support. This implant was first inserted in a thoracodorsal artery perforator flap for primary integration before the free transfer of the complete structure, two months later. The free transfer was successful without any complication. A stable reconstruction and satisfying result was obtained. The patient did not want additional surgical improvement 24 months post-operatively, and resumed his professional activities. The possibility of using three dimensional custom titanium prostheses to replace the bone and cartilage support seems to be an interesting alternative for patients in the failure situation of nasal reconstruction.

AB - The "shock and kill" HIV-1 cure strategy proposes eradication of stable cellular reservoirs by clinical treatment with latency-reversing agents (LRAs). Although resting CD4+ T cells latently infected with HIV-1 constitute the main reservoir that is targeted by these approaches, their consequences on other reservoirs such as the central nervous system are still unknown and should be taken into consideration. We performed experiments aimed at defining the possible role of astrocytes in HIV-1 persistence in the brain and the effect of LRA treatments on this viral sanctuary. We first demonstrate that the diminished HIV-1 production in a proliferating astrocyte culture is due to a reduced proliferative capacity of virus-infected cells compared with uninfected astrocytes. In contrast, infection of non-proliferating astrocytes led to a robust HIV-1 infection that was sustained for over 60 days. To identify astrocytes latently infected with HIV 1, we designed a new dual-color reporter virus called NL4.3 eGFP-IRES-Crimson that is fully infectious and encodes for all viral proteins. Although we detected a small fraction of astrocytes carrying silent HIV-1 proviruses, we did not observe any reactivation using various LRAs and even strong inducers such as tumor necrosis factor, thus suggesting that these proviruses were either not transcriptionally competent or in a state of deep latency. Our findings imply that astrocytes might not constitute a latent reservoir per se but that relentless virus production by this brain cell population could contribute to the neurological disorders seen in HIV-1-infected persons subjected to combination antiretroviral therapy. PMID- 29464786 TI - Polymer-free drug-eluting stents for coronary artery disease. AB - Polymer-free drug-eluting stents (PF-DES) were designed with the expectation of avoiding late restenosis and thrombosis related to the polymer used in traditional DES platforms. Furthermore, due to similarities with bare metal stents after drug elution, PF-DES has been considered as particularly suitable for patients at high bleeding risk. A variety of PF-DES platforms have been clinically tested. Despite their theoretical advantages, PF platforms showed comparable clinical outcomes with modern permanent- or biodegradable polymer based DES up to 5 years after implantation. Use of more biocompatible polymers on the modern DES platforms is one of the reasons therefore. Their improved safety profile allows already less intensive antithrombotic regimes after DES. Hence, nowadays PF-DES platforms can be considered as one of many DES options for percutaneous treatment of coronary artery disease. PMID- 29464787 TI - Skin microbiota and human 3D skin models. AB - Although the role of the microbiota in skin homeostasis is still emerging, there is growing evidence that an intact microbiota supports the skin barrier. The increasing number of research efforts that are trying to shed more light on the human skin-microbiota interaction requires the use of suitable experimental models. Three-dimensional (3D) skin equivalents have been established as a valuable tool in dermatological research because they contain a fully differentiated epidermal barrier that reflects the morphological and molecular characteristics of normal human epidermis. In this review, we provide an overview of current 3D skin models and illustrate the potential of 3D skin models to study the human skin-microbiota interplay. PMID- 29464788 TI - The impact of child welfare legislation on domestic violence-related homicide rates. AB - State-specific statutes providing legal consequences for perpetrating domestic violence in the presence of a child have been enacted across the United States between 1996 and 2012. This paper examines the impact of this child welfare legislation, using a difference-in-differences approach. We find a significant drop in domestic violence-related homicide rates, when considering a wide range of victim-offender relationships. However, this result does not hold for marital homicides, suggesting that for this subpopulation, the risk of reprisal and consequent reduction in reporting may be counterbalancing the hypothesized deterrent impacts of the legislation. PMID- 29464789 TI - Surgical outcomes of mitral valve replacement with concomitant mitral annular reconstruction. AB - BACKGROUND AND AIM OF THE STUDY: We evaluated the early and long-term outcomes of mitral annular reconstruction (MAR) with pericardium during mitral valve replacement (MVR), and analyzed the risk factors associated with post-operative mortality. METHODS: Between May 1997 and April 2013, 78 consecutive patients underwent MVR with MAR. The indications for MAR were treatment for annular infection in native valve endocarditis (n = 23, 29.5%) or prosthetic valve endocarditis (n = 26, 33.3%), reinforcement of damaged annulus resulting from a previous operation (n = 17, 21.8%), complete excision of extensive calcification (n = 9, 11.5%), and left ventricular or left atrial rupture (n = 3, 3.8%). Patients were classified into infective endocarditis (n = 49) and non endocarditis groups (n = 29). The mean follow-up period was 59.4 +/- 47.3 months. RESULTS: There were two operative deaths and 11 cases of late mortality in the endocarditis group and five cases in the non-endocarditis group. Late prosthetic valve endocarditis occurred in four patients. The overall survival rate at 1 and 10 years was 94.8% and 65.1%, respectively. There was no statistical difference in the overall survival, freedom from reoperation, and freedom from endocarditis rates between the groups (P = 0.565, P = 0.635, and P = 0.449, respectively). Univariable and multivariable analyses revealed that pre-operative left ventricular dysfunction (ejection fraction <40%) was an independent predictor of overall mortality. CONCLUSIONS: The early and long-term results of MAR with pericardium during MVR are acceptable in both endocarditis and non-endocarditis patients. PMID- 29464790 TI - Constrained Chemical Dynamics of CO Dissociation/Hydrogenation on Rh Surfaces. AB - Among noble metal catalysts, rhodium (Rh) is unique in its ability to perform a one-step synthesis of ethanol from syngas. The first steps following the adsorption of syngas on Rh surfaces are assumed to be responsible for the conversion of CO and the selectivity effects between C1 , C2 , and oxygenated species. In the current work, constrained ab initio molecular dynamics are applied to investigate the kinetics of CO dissociation and hydrogenation over flat and stepped Rh surfaces. The obtained barriers for the Rh(111) surface are in good agreement with the literature data. On the stepped Rh(211) surface, a large site-dependent variation in barrier height is shown, with the upper terrace exhibiting behavior comparable to the Rh(111) surface, whereas the barriers over the lower terrace site are generally significantly lower. The rate constants are calculated using transition state theory for both surfaces, and are applied successfully in a microkinetic model, confirming the predicted impact on CO conversion and CH4 /C1 -oxygenate/C2 Hn selectivity. In addition to the high accuracy energetics and rate constants reported for CO dissociation/hydrogenation and the presentation of an updated microkinetic mechanism for Rh catalysts, the applicability of constrained molecular dynamics for reaction barrier calculation is confirmed, and sensitive pathways affecting the selectivity between formaldehyde/methanol over Rh catalysts are highlighted.

PMID- 29464791 TI - Comparing pharmacological treatments for cocaine dependence: Incorporation of methods for enhancing generalizability in meta-analytic studies. AB - OBJECTIVES: Few head-to-head comparisons of cocaine dependence medications exist, and combining data from different randomized controlled trials (RCTs) is fraught with methodological challenges including limited generalizability of the RCT findings. This study applied a novel meta-analytic approach to data of cocaine dependence medications. METHODS: Data from 4 placebo-controlled RCTs (Reserpine, Modafinil, Buspirone, and Ondansetron) were obtained from the National Institute of Drug Abuse Clinical Trials Network (n = 456). The RCT samples were weighted to resemble treatment-seeking patients (Treatment Episodes Data Set-Admissions) and individuals with cocaine dependence in general population (National Survey on Drug Use and Health). We synthesized the generalized outcomes with pairwise meta analysis using individual-level data and compared the generalized outcomes across the 4 RCTs with network meta-analysis using study-level data. RESULTS: Weighting the data by the National Survey on Drug Use and Health generalizability weight made the overall population effect on retention significantly larger than the RCT sample effect. However, there was no significant difference between the population effect and the RCT sample effect on abstinence. Weighting changed the ranking of the effectiveness across treatments. CONCLUSIONS: Applying generalizability weights to meta-analytic studies is feasible and potentially provides a useful tool in assessing comparative effectiveness of treatments for substance use disorders in target populations.

PMID- 29464796 TI - Drug-like dietary vanilloids induce anticancer activity through proliferation inhibition and regulation of bcl-related apoptotic proteins. AB - In this study, a series of 20 structurally similar vanilloids (Vn) were tested for their antiproliferative effects against 12 human cancer cells: human breast (MCF-7 and MDA-MB-231), cervical (HeLa), ovarian (Caov-3), lung (A549), liver (HepG2), colorectal (HT-29 and HCT116), nasopharyngeal (CNE-1 and HK-1), and leukemic (K562 and CEM-SS) cancer cells. Among all the tested vanilloids, Vn16 (6 shogaol) exhibited the most potent cytotoxic effects against human colorectal cancer cells (HT-29). The apoptotic induction effects exhibited by Vn16 on HT-29 cells were confirmed using dual staining fluorescence microscopy and enzyme linked immunosorbent assay. The effects of Vn16 on regulation of 43 apoptotic related markers were determined in HT-29. The results suggested that 8 apoptotic markers (caspase 8, BAD, BAX, second mitochondrial-derived activator, caspase 3, survivin, bcl-2, and cIAP-2) were either upregulated or downregulated. These results further support the chemopreventive properties of foods that contain vanilloids.

(Annonaceae) is a medicinal plant traditionally used in Mozambique to treat infectious diseases. The aim of this study was to find resistance modifiers in C. kirkii for Gram-positive and Gram negative model bacterial strains. One of the most important resistance mechanisms in bacteria is the efflux pump-related multidrug resistance. Therefore, polycarpol (1), three C-benzylated flavanones (2-4), and acetylmelodorinol (5) were evaluated for their multidrug resistance-reverting activity on methicillin susceptible and methicillin-resistant Staphylococcus aureus and Escherichia coli AG100 and AG100 A strains overexpressing and lacking the AcrAB-TolC efflux pump system. The combined effects of antibiotics and compounds (2 and 4) were also assessed by using the checkerboard microdilution method in both S. aureus strains. The relative gene expression of the efflux pump genes was determined by real-time reverse transcriptase quantitative polymerase chain reaction. The inhibition of quorum sensing was also investigated. The combined effect of the antibiotics and compound 2 or 4 on the methicillin-sensitive S. aureus resulted in synergism. The most active compounds 2 and 4 increased the expression of the efflux pump genes. These results suggested that C. kirkii constituents could be effective adjuvants in the antibiotic treatment of infections. PMID- 29464799 TI - Antiproliferative activity and apoptosis induction by trijuganone C isolated from the root of Salvia miltiorrhiza Bunge (Danshen). AB - In this study, we found that the hexane fraction of Danshen, the dried root of Salvia miltiorrhiza (Lamiaceae), exerted antiproliferative effects on human leukemia cells. Phytochemical investigation of the hexane fraction achieved the isolation of the tanshinone diterpenes: dihydrotanshinone I (1), trijuganone C (2), trijuganone B (3), cryptotanshinone (4), tanshinone IIA (5), and tanshinone I (6). Compound 2 showed significant antiproliferative activities against human leukemia cells HL-60, Jurkat, and U937. The antiproliferative activities of 2 against human cancer and normal cells indicated that 2 exhibited potent antiproliferative activities with IC50 values less than 10 MUM against HL-60 and Jurkat cells as well as on the colon cancer cells DLD-1, COLO 205, and Caco-2. Compound 2 induced chromatin condensation, DNA fragmentation, activation of caspase-3, -8, and -9, and the cleavage of poly (ADP-ribose) polymerase (PARP) in HL-60 cells. Moreover, 2 activated Bid and Bax, leading to the loss of mitochondrial membrane potential, and 2 induced the cytochrome c release from mitochondria into cytosol. In contrast, Bcl-2 and Bcl-xL were unaffected by 2. These results suggest that 2 exerts antiproliferative effects via apoptosis induction mediated by mitochondrial dysfunction and caspase activation. Compound 2 may serve as a candidate of potential chemotherapeutic agent for human leukemia. PMID- 29464800 TI - Gender differences in retirement planning: A longitudinal study among Spanish Registered Nurses. AB - BACKGROUND: Consistent patterns of gender differences in retirement planning behaviours have been shown but little is known about these behaviours among nurses. AIMS: To analyse the antecedents of the behaviours to prepare for retirement in nurses older than 55 and to identify differences as a function of gender. METHODS: A two-wave longitudinal study with Spanish nurses (n = 132). RESULTS: Statistically significant gender differences were revealed. Specifically, paths from financial knowledge to public protection and self insurance as well as paths from goals clarity to public protection all differed by gender. CONCLUSIONS: Patterns of retirement planning differentiated by gender apparently continue to emerge. IMPLICATIONS FOR NURSING MANAGEMENT: The study adds evidence showing that female nurses continue to rely on public protection as a solid support for their retirement. Despite their greater awareness of the importance of health care and social relations, savings and finance are more neglected by female nurses. Intervention should be aimed at fostering financial literacy of the entire nursing population, but particularly, the access of women to this training. Secondly, given that the differences persist, advance planning of social actions to protect those who will be living alone and economically helpless in old age. PMID- 29464802 TI - Comparison of stratum corneum thickness between two proposed methods of calculation using Raman spectroscopic depth profiling of skin water content. AB - BACKGROUND/PURPOSE: The stratum corneum (SC) is the most important layer for the barrier function of skin, so investigation of the SC is very important in cosmetic and medical research. Here, we calculated the SC thickness using the depth profile of the skin's water concentration based on previously described methods, and then compared the results. METHODS: Seven Korean women in their 30s participated in this study. Raman spectroscopy was used to measure the in vivo depth profile of skin water concentration. A total of 21 areas were measured at forearm. Microsoft Excel 2007 was used to calculate SC thickness based on the slope and intersection methods. RESULTS: The slope method and the intersection method gave a forearm SC thickness calculated at 21.3 +/- 2.6 MUm and 17.6 +/- 2.8 MUm, respectively. There was a significant difference between the two calculation methods but the two methods showed strong correlation of SC thickness results (r = .899). CONCLUSION: Although there was a difference in calculated SC thickness of about 20% between the two methods, these results reveal that the two SC thickness calculation methods using Raman spectroscopy were suitable for measuring SC thickness, a finding consistent with other published results.

PMID- 29464801 TI - Herbal medicine for depression and anxiety: A systematic review with assessment of potential psycho-oncologic relevance. AB - Anxiety and depression are prevalent among cancer patients, with significant negative impact. Many patients prefer herbs for symptom relief to conventional medications which have limited efficacy/side effects. We identified single-herb medicines that may warrant further study in cancer patients. Our search included PubMed, Allied and Complementary Medicine, Embase, and Cochrane databases, selecting only single-herb randomized controlled trials between 1996 and 2016 in any population for data extraction, excluding herbs with known potential for interactions with cancer treatments. One hundred articles involving 38 botanicals met our criteria. Among herbs most studied (>=6 randomized controlled trials each), lavender, passionflower, and saffron produced benefits comparable to standard anxiolytics and antidepressants. Black cohosh, chamomile, and chasteberry are also promising. Anxiety or depressive symptoms were measured in all studies, but not always as primary endpoints. Overall, 45% of studies reported positive findings with fewer adverse effects compared with conventional medications. Based on available data, black cohosh, chamomile, chasteberry, lavender, passionflower, and saffron appear useful in mitigating anxiety or depression with favorable risk-benefit profiles compared to standard treatments. These may benefit cancer patients by minimizing medication load and accompanying side effects. However, well-designed larger clinical trials are needed before these herbs can be recommended and to further assess their psycho-oncologic relevance. PMID- 29464804 TI - Policy-relevant behaviours predict heavier drinking and mediate the relationship with age, gender and education status: Analysis from the International Alcohol Control Study. AB - INTRODUCTION AND AIMS: To investigate behaviours related to four alcohol policy variables (policy-relevant behaviours) and demographic variables in relation to typical quantities of alcohol consumed on-premise in six International Alcohol Control study countries. DESIGN AND METHODS: General population surveys with drinkers using a comparable survey instrument and data analysed using path analysis in an overall model and for each country. MEASURES: typical quantities per occasion consumed on-premise; gender, age; years of education, prices paid, time of purchase, time to access alcohol and liking for alcohol advertisements. RESULTS: In the overall model younger people, males and those with fewer years of education consumed larger typical quantities. Overall lower prices paid, later time of purchase and liking for alcohol ads predicted consuming larger typical quantities; this was found in the high-income countries, less consistently in the high-middle-income countries and not in the low middle-income country. Three policy-relevant behaviours (prices paid, time of purchase, liking for alcohol ads) mediated the relationships between age, gender, education and consumption in high-income countries. DISCUSSION AND CONCLUSIONS: International Alcohol Control survey data showed a relationship between policy-relevant behaviours and typical quantities consumed and support the likely effect of policy change (trading hours, price and restrictions on marketing) on heavier drinking. The path analysis also revealed policy-relevant behaviours were significant mediating variables between the effect of age, gender and educational status on consumption. However, this relationship is clearest in high-income countries. Further research is required to understand better how circumstances in low-middle income countries impact effects of policies.

AB - The embryonic and early larval development of laboratory reared Zagros tooth carp, Aphanius vladykovi Coad, 1988, are described and illustrated. Development and embryogenesis start with the external fertilization of sticky, transparent and spherical telolecithal/macrolecithal eggs with a mean diameter of 1.61+/- 0.12 mm and it continues with meroblastic/radial cleavage, blastulation/blastula formation, epibolic cell migration during gastrulation and organogenesis resulting in a newly hatched larvae of 5.23 +/- 0.09 mm in length with attached yolk sac at about 164 hr (at 24 +/- 1 degrees C) after fertilization. PMID- 29464807 TI - Leadership practices of nurse managers for implementing evidence-based nursing in China. AB - AIM: To explore leadership of Chinese nurse managers in evidence-based nursing implementation. BACKGROUND: Despite much in the literature that highlights the significance of involving nurse managers, the qualitative nature of how their leadership practices influence the evidence implementation has not yet been fully explored. METHODS: A qualitative secondary data analysis was conducted on 15 transcripts of interviews of nurse managers from a parent grounded theory study. The method for analysis employed the directed content analysis approach, using the framework of Kouzes & Posner's Five Practices of Exemplary Leadership(r) model. RESULTS: All the leadership practice categories of Five Practices of Exemplary Leadership(r) were observed in the data. Two additional categories "getting oneself prepared" and "keep it going" were also identified as important leadership practices of nurse managers to exhibit during evidence-based practice implementation. CONCLUSION: This study advances the leadership model by providing validation of existing exemplars and suggests two new practices with exemplars for a better understanding of the nurse managers' role during evidence implementation. IMPLICATIONS FOR NURSING MANAGEMENT: Strategies are proposed to recognise, value and prepare nurse managers' leadership practices during evidence implementation. Emphasis should also be put on cultivating and developing individual nurses' professional practice to sustain evidence-based practice. PMID- 29464806 TI - Histopathological and immunophenotypic features of ipilimumab-associated colitis compared to ulcerative colitis. AB - BACKGROUND: Use of the immune checkpoint inhibitor ipilimumab is sometimes complicated by ipilimumab-associated colitis (Ipi-AC), an immune-mediated colitis that mimics inflammatory bowel disease. OBJECTIVE: We sought to characterize the histopathologic and immunophenotypic features of Ipi-AC and to directly compare these features to ulcerative colitis (UC). METHODS: This is a retrospective cohort study of 22 patients with Ipi-AC, 12 patients with treatment-naive UC and five controls with diarrhoea but normal endoscopic findings. Immunohistopathologic features were described, and quantitative immunohistochemistry (IHC) was performed for CD4, CD8, CD20, CD138 and FOXP3. RESULTS: Endoscopic findings in both the Ipi-AC and UC groups included ulcerated, oedematous and erythematous mucosa. Involvement of the GI tract was more diffuse in Ipi-AC. As compared to UC, a smaller proportion of Ipi-AC biopsies had basal plasmacytosis (14% for Ipi-AC vs. 92% for UC, P < 0.0001) and crypt distortion (23% for Ipi-AC vs. 75% for UC, P = 0.003), whereas Ipi-AC biopsies had more apoptotic bodies in the left colon (17.6 +/- 15.3 for Ipi-AC vs. 8.2 +/- 4.2 for UC, P = 0.011). Cryptitis, ulcerations and crypt abscesses were common in both groups. Biopsy specimens from Ipi-AC had a lower density of CD20-positive lymphocytes than UC (275.8 +/- 253.3 cells mm-2 for Ipi-AC vs. 1173.3 +/- 1158.2 cells mm-2 for UC, P = 0.022) but had a similar density of CD4, CD8, CD138 and FOXP3-positive cells. CONCLUSIONS: Ipi-AC is a distinct pathologic entity with notable clinical and histopathological differences compared to UC. These findings provide insights into the pathophysiology of immune-related adverse events (iAEs) from ipilimumab therapy. PMID- 29464808 TI - Cancer diagnosis in patients with heart failure: epidemiology, clinical implications and gaps in knowledge. AB - Cancer and heart failure (HF) are common medical conditions with a steadily rising prevalence in industrialized countries, particularly in the elderly, and they both potentially carry a poor prognosis. A new diagnosis of malignancy in subjects with pre-existing HF is not infrequent, and challenges HF specialists as well as oncologists with complex questions relating to both HF and cancer management. An increased incidence of cancer in patients with established HF has also been suggested. This review paper summarizes the epidemiology and the prognostic implications of cancer occurrence in HF, the impact of pre-existing HF on cancer treatment decisions and the impact of cancer on HF therapeutic options, while providing some practical suggestions regarding patient care and highlighting gaps in knowledge. PMID- 29464809 TI - Mapping and characterization of positive and negative BOLD responses to visual stimulation in multiple brain regions at 7T. AB - External stimuli and tasks often elicit negative BOLD responses in various brain regions, and growing experimental evidence supports that these phenomena are functionally meaningful. In this work, the high sensitivity available at 7T was explored to map and characterize both positive (PBRs) and negative BOLD responses (NBRs) to visual checkerboard stimulation, occurring in various brain regions within and beyond the visual cortex. Recently-proposed accelerated fMRI techniques were employed for data acquisition, and procedures for exclusion of large draining vein contributions, together with ICA-assisted denoising, were included in the analysis to improve response estimation. Besides the visual cortex, significant PBRs were found in the lateral geniculate nucleus and superior colliculus, as well as the pre-central sulcus; in these regions, response durations increased monotonically with stimulus duration, in tight covariation with the visual PBR duration. Significant NBRs were found in the visual cortex, auditory cortex, default-mode network (DMN) and superior parietal lobule; NBR durations also tended to increase with stimulus duration, but were significantly less sustained than the visual PBR, especially for the DMN and superior parietal lobule. Responses in visual and auditory cortex were further studied for checkerboard contrast dependence, and their amplitudes were found to increase monotonically with contrast, linearly correlated with the visual PBR amplitude. Overall, these findings suggest the presence of dynamic neuronal interactions across multiple brain regions, sensitive to stimulus intensity and duration, and demonstrate the richness of information obtainable when jointly mapping positive and negative BOLD responses at a whole-brain scale, with ultra high field fMRI. PMID- 29464810 TI - Prevalence and risk of sport types to stress urinary incontinence in sportswomen: A cross-sectional study. AB - OBJECTIVE: The objective of our study was to investigate the prevalence and risk of developing stress urinary incontinence (SUI) in each type of high-intensity sport, and the associated impact on quality of life in sportswomen. METHODS: This cross-sectional study was conducted between March and November 2016. The study included 278 sportswomen. The basic inclusion criteria were being nulliparous and engaging in high-intensity physical activity. The exclusion criteria were childbirth, surgical treatment of gynecological and urological illnesses and urinary tract infection. For evaluation were used: The International Physical Activity Questionnaire (IPAQ), The International Consultation on Incontinence Questionnaire Urinary Incontinence (ICIQ-UISF), the Overactive Bladder Questionnaire (OAB-q), the Urinary Incontinence Quality of Life Scale (I-QOL). RESULTS: The highest percentage of SUI was found in athletes (23.8%), followed by volleyball players (19.6%). We found that cumulative metabolic equivalent (MET) did not affect SUI, but the type of sport did. The risk of SUI was highest in volleyball sportswomen (odds ratio[OR] = 2.16,95% confidence interval[CI] = 0.96 4.89, P < 0.05) and athletes (OR = 2.56,95%CI = 0.87-7.51, P = 0.08). As assessed by the I- QOL, SUI in people who participated in fitness and athletics (e.g., basketball, volleyball and handball) had a negative impact on quality of life including behavior, psychosocial impacts and social embarrassment score. CONCLUSION: Volleyball players have a 116% chance of getting SUI compared to women who play other types of sports that were analyzed as part of this study. Healthcare professionals should inform the population of sportswomen with risk factors for SUI in order to implement preventive physiotherapy for strengthening pelvic floor muscles. PMID- 29464811 TI - Novel splice site mutation in the LIPH gene in a patient with autosomal recessive woolly hair/hypotrichosis: Case report and published work review. AB - Autosomal recessive woolly hair is a relatively rare hereditary hair disorder characterized by sparse, short, curly hair. This condition is known to be caused by mutations in the LIPH gene, LPAR6 gene or KRT25 gene. In the Japanese population, most patients with autosomal recessive woolly hair carry one of two founder mutations in the LIPH gene, c.736T>A (p.Cys246Ser) or c.742C>A (p.His248Asn). However, occasionally, individuals with this condition carry compound heterozygous mutations, typically one founder mutation and another mutation. In this study, we describe a patient with a compound heterozygous mutation in the LIPH gene at c.736T>A and c.1095-3C>G. The latter mutation created a novel splice site. This was the fourth splice site mutation to be described in the LIPH gene. Furthermore, we performed an in vitro transcription assay in cultured cells, and demonstrated that the c.1095-3C>G mutation led to a frame-shift, which created a premature termination codon at the protein level (p.Glu366Ilefs*7). Finally, we summarized the mutations previously reported for the LIPH gene. Our findings provide further clues as to the molecular basis of autosomal recessive woolly hair. PMID- 29464812 TI - The female continence mechanism measured by high resolution manometry: Urethral bulking versus midurethral sling. AB - AIMS: Traditional technology to characterize urethral pressure changes during dynamic conditions is limited by slow response times or artifact-inducing withdrawal maneuvers. The 8F high-resolution manometry (HRM) catheter (ManoScanTM ESO, Covidien) has advantages of fast response times and the ability to measure urethral pressures along the urethral length without withdrawal. Our objective was to determine static and dynamic maximum urethral closure pressures (MUCPs) and resting functional urethral length (FUL) in women using HRM before and after transurethral bulking and compare results to other women who underwent midurethral sling (MUS). METHODS: We recorded rest, cough, and strain MUCPs and FUL in 24 women before and after transurethral bulking with polydimethylsiloxane (Macroplastique(r)) using the HRM catheter and compared these changes to HRM values from 26 women who had the same measures before and after MUS. RESULTS: At rest, MUCPs increased minimally after both urethral bulking and MUS (3 vs 0.4 cm H2 O respectively, P = 0.4). Under dynamic conditions there were statistically insignificant small increases in MUCP and these increases were markedly less than after MUS (cough: 1.5 vs 63.8 cm H2 O, P < 0.001 and strain: 11.5 vs 57.7 cm H2 O, P < 0.001). FUL increased by 0.5 cm after transurethral bulking (P = 0.003), and decreased by 0.25 cm after MUS placement (P = 0.012). CONCLUSIONS: The mechanism of continence after urethral bulking differs from MUS. While MUS increases dynamic MUCP, bulking may rely on increasing the length of the continence zone. PMID- 29464813 TI - The economic burden of overactive bladder (OAB) and its effects on the costs associated with other chronic, age-related comorbidities in the United States. AB - AIMS: The prevalence of OAB increases with age and is associated with several chronic comorbidities. However, the impact of OAB on the healthcare costs of patients with such comorbidities is not well-understood. This study aimed to quantify the impact of OAB on healthcare costs and assess the potential moderating effects of OAB on the costs of patients with chronic comorbidities. METHODS: Adults with evidence of OAB/OAB-related therapy between 1/1/2008 12/31/2013 were identified from two large, administrative claims databases. Per patient-per-month (PPPM) expenditures for OAB cases were estimated and compared to those of propensity score-matched subjects without OAB. Costs were modeled using ordinary least squares regression including main effects and interactions of chronic depression, dementia, diabetes, hypertension, and osteoporosis with OAB. Values for the comparisons were calculated on the original dollar scale using smearing estimators. RESULTS: A total of 110 059 pairs of OAB cases and matched non-OAB controls were identified. The mean, multivariable-adjusted, PPPM all-cause costs of OAB cases from the model without interactions were $3003, compared to $1123 for matched controls (P < 0.0001). In the model assessing the interactions of chronic comorbidities with OAB, those OAB patients with comorbid depression, dementia, diabetes, hypertension, and osteoporosis incurred significantly higher costs than controls with these comorbidities. The synergistic effect of these interactions was estimated to be $95-$574 PPPM. CONCLUSIONS: Within this US-based population, the healthcare costs of OAB patients were more than 2.5 times those of similar patients without OAB. Additionally, patients with OAB and chronic, age-related comorbidities incurred higher healthcare costs than non-OAB controls with the same comorbidities. PMID- 29464814 TI - DRD2 promoter methylation and measures of alcohol reward: functional activation of reward circuits and clinical severity. AB - Studies have identified strong associations between D2 receptor binding potential and neural responses to rewarding stimuli and substance use. Thus, D2 receptor perturbations are central to theoretical models of the pathophysiology of substance dependence, and epigenetic changes may represent one of the fundamental molecular mechanisms impacting the effects of alcohol exposure on the brain. We hypothesized that epigenetic alterations in the promoter region of the dopamine D2 receptor (DRD2) gene would be associated with cue-elicited activation of neural reward regions, as well as severity of alcohol use behavior. The current study leveraged functional neuroimaging (fMRI) during an alcohol reward paradigm (n = 383) to test associations among DRD2 promoter methylation in peripheral tissue, signal change in the striatum during the presentation of alcohol cues, and severity of alcohol use disorder (AUD). Controlling for age, DRD2 promoter methylation was positively associated with responses to alcohol cues in the right accumbens (partial r = 0.144, P = 0.005), left putamen (partial r = 0.133, P = 0.009), right putamen (partial r = 0.106, P = 0.039), left caudate (partial r = 0.117, P = 0.022), and right caudate (partial r = 0.133, P = 0.009), suggesting that DRD2 methylation was positively associated with robust activation in the striatum in response to reward cues. DRD2 methylation was also positively associated with clinical metrics of AUD severity. Specifically, controlling for age, DRD2 methylation was associated with Alcohol Use Disorders Identification Test total (partial r = 0.140, P = 0.002); Impaired Control Scale total (partial r = 0.097, P = 0.044) and Alcohol Dependence Scale total (partial r = 0.152, P = 0.001). Thus, DRD2 methylation may be a critical mechanism linking D2 receptors with functional striatal brain changes and clinical severity among alcohol users. PMID- 29464816 TI - On the issue of choosing psychodiagnostic methods of measuring and scoring of cognitive deficit in case of schizophrenia. AB - RATIONALE, AIMS, AND OBJECTIVES: The article is dedicated to the search of more accurate psychodiagnostic methods and methods of evaluation that can help to define the degree of manifestation of cognitive deficiency among patients suffering from various schizophrenic disorders. The notions of cognitive deficiency and cognitive profile are analysed; we understand them as the correlation between intact and damaged components of cognitive processes and their diagrammatic representation. The authors prove that it is essential to provide a detailed scale of cognitive deficiencies detectable in case of schizophrenic disorders and to design universal algorithms that could translate the results of traditional content analysis of cognitive disorders into quantitative indicators. The article is based on the authors' experiments. We examined 128 patients, among whom 76 were suffering from paranoid schizophrenia (F20 according to ICD) and 52 were suffering from schizotypal disorder (F21 according to ICD). METHOD: In evaluation of cognitive deficiency, we used both traditional methods devised in Russia and foreign tests that are seldom used by medical psychologists in their daily practice. We have analysed the difference in doing the cognitive tests between the groups of patients with different forms of schizophrenia and also suffering from it for different periods (up to 5 y and more than 5 y). RESULTS: On the basis of the quantitative indicators, a cognitive profile of each particular illness was compiled. As a result, we have defined different varieties of cognitive deficiency depending on the symptoms and dynamics of the disease. CONCLUSION: The authors have provided a detailed description of the structure and dynamics of the cognitive deficiency in case of different forms of schizophrenia and compiled cognitive profiles based on those data. PMID- 29464815 TI - Hepatic elastin content is predictive of adverse outcome in advanced fibrotic liver disease. AB - AIMS: The aim of this study was to determine if elastin content in needle core native liver biopsies was predictive of clinical outcome in patients with chronic hepatitis C virus-related chronic liver disease. METHODS AND RESULTS: Elastin contents in liver biopsies were determined by image analysis, technically validated in an independent centre, and correlated with outcome in patients with advanced (Ishak stage >=5) chronic hepatitis C virus-related chronic liver disease. Elastin was robustly quantified in an operator-independent and laboratory-independent manner, with very strong correlation of elastin staining measured with two methods of image classification (rs = 0.873, P < 0.00001). Elastin content (but not absolute scar content or Ishak stage) was predictive for future clinical outcomes. In a cohort of patients without sustained virological response, the median hepatic elastin content was 3.4%, and 17 patients (57%) progressed to a liver-related clinical outcome; 11 of the 15 patients (73%) with a hepatic elastin content of >3.4% progressed to a clinical outcome, as compared with only six of 15 (40%) with an elastin content of <3.4%. The difference in time to outcome was significant. CONCLUSIONS: We describe a simple and reproducible method for elastin quantification in liver biopsies that provides potentially valuable prognostic information to inform clinical management. PMID- 29464817 TI - The role of angiotensin receptor-neprilysin inhibitors in cardiovascular disease existing evidence, knowledge gaps, and future directions. AB - Although traditional renin-angiotensin system antagonists including angiotensin converting enzyme inhibitors and angiotensin receptor blockers have revolutionized the treatment of cardiovascular disease (CVD), the pivotal PARADIGM-HF trial demonstrated that sacubitril/valsartan, an angiotensin receptor neprilysin inhibitor (ARNI), was superior to an angiotensin-converting enzyme inhibitor in reducing cardiovascular morbidity and mortality in patients with heart failure and reduced ejection fraction. However, despite international regulatory approval and strong recommendations in the guidelines, uptake of sacubitril/valsartan has been disappointing. Sacubitril/valsartan is now the focus of a large programme of clinical trials testing the hypothesis that ARNIs may supplant conventional renin-angiotensin system inhibitors across the spectrum of CVD, including hypertension, secondary prevention after myocardial infarction, and heart failure with preserved ejection fraction. This review summarizes the existing evidence, knowledge gaps, and future directions of ARNIs in CVD based on discussions between clinical trialists, industry representatives, and regulatory authorities at the 2016 Global CardioVascular Clinical Trialists Forum in Washington, D.C.

PMID- 29464819 TI - Mentalization and the left inferior frontal gyrus and insula. AB - OBJECTIVE: To determine if an interpersonal attribution bias associated with self perception, the externalizing bias, was related to neural activations during mentalization. METHODS: A functional magnetic resonance imaging task involving verbal appraisals measured neural activations when thinking about oneself and others in 59 adults, including healthy women as well as women with and recovered from anorexia nervosa. Whole-brain regressions correlated brain function during mentalization with the externalizing bias measured using the Internal, Personal, and Situational Attributions Questionnaire. RESULTS: Women with anorexia nervosa had a lower externalizing bias, demonstrating a tendency to self-attribute more negative than positive social interactions, unlike the other groups. The externalizing bias was correlated with activation of the left inferior frontal gyrus and posterior insula, when comparing thinking about others evaluating oneself with direct self-evaluation. DISCUSSION: Externalizing biases may provide an office-based assay reflecting neurocognitive disturbances in social self perception that are common during anorexia nervosa. PMID- 29464821 TI - Determination of adsorption and desorption of DNA molecules on freshwater and marine sediments. AB - AIMS: Free DNA and its adsorption by sediment in the aquatic environment lead to ambiguity in the identification of recent faecal pollution sources. The goal of this study was to understand the mechanisms of DNA adsorption and desorption on aquatic sediment under various conditions using quantitative polymerase chain reaction (qPCR). METHODS AND RESULTS: Both raw sewage (RS) DNA and purified PCR product (PPP) were used in adsorption and desorption experiments; autoclaved freshwater and marine sediments served as sorbents. Thirty-six hours were needed for adsorption to reach equilibrium. More DNA was adsorbed on both sediments in stream water than in 5 mmol l-1 NaCl and DNA adsorption increased in the presence of Ca2+ and Mg2+ . Successive desorption experiments showed that between 5% and 22% of adsorbed DNA was desorbed. CONCLUSIONS: Organic matter and clay played a significant role in determining the DNA adsorption capacity on sediment. The data suggest the presence of multilayer adsorption. DNA molecules on sediments were mostly adsorbed through ligand binding rather than electrostatic binding. SIGNIFICANCE AND IMPACT OF THE STUDY: Quantitative polymerase chain reaction assays provide a better way to investigate the DNA adsorption and desorption mechanisms by sediment. DNA desorption can potentially complicate the outcomes of microbial source tracking studies. PMID- 29464823 TI - Caudal articular process dysplasia of thoracic vertebrae in neurologically normal French bulldogs, English bulldogs, and Pugs: Prevalence and characteristics. AB - The aims of this study were to evaluate the prevalence and anatomical characteristics of thoracic caudal articular process dysplasia in French bulldogs, English bulldogs and Pugs presenting for problems unrelated to spinal disease. In this retrospective cross-sectional study, computed tomography scans of the thoracic vertebral column of these three breeds were reviewed for the presence and location of caudal articular process hypoplasia and aplasia, and compared between breeds. A total of 271 dogs met the inclusion criteria: 108 French bulldogs, 63 English bulldogs, and 100 Pugs. A total of 70.4% of French bulldogs, 84.1% of English bulldogs, and 97.0% of Pugs showed evidence of caudal articular process dysplasia. Compared to French and English bulldogs, Pugs showed a significantly higher prevalence of caudal articular process aplasia, but also a lower prevalence of caudal articular process hypoplasia, a higher number of affected vertebrae per dog and demonstrated a generalized and bilateral spatial pattern more frequently. Furthermore, Pugs showed a significantly different anatomical distribution of caudal articular process dysplasia along the vertebral column, with a high prevalence of caudal articular process aplasia between T10 and T13. This area was almost completely spared in French and English bulldogs. As previously suggested, caudal articular process dysplasia is a common finding in neurologically normal Pugs but this also seems to apply to French and English bulldogs. The predisposition of clinically relevant caudal articular process dysplasia in Pugs is possibly not only caused by the higher prevalence of caudal articular process dysplasia, but also by breed specific anatomical characteristics. PMID- 29464824 TI - Evaluation of electron tomography reconstruction methods for interface roughness measurement. AB - We evaluate the suitability of simultaneous iterative reconstruction technique (SIRT), filtered back projection, and simultaneous algebraic reconstruction technique methods for buried interface roughness measurements. We also investigate the effect of total electron dose distributed over the entire tilt series on measured roughness values. We investigate the applicability of the dose fractionation theorem by evaluating the effect of an increasing number of images, i.e., decreasing tilt increment size at fixed total electron irradiation dose on the quantitative measurement of buried interface roughness. The results indicate that SIRT is the most suitable method for reconstruction and a 3 degrees to 5 degrees angle is optimal for the roughness measurement. PMID- 29464825 TI - Performance of pre-RT-qPCR treatments to discriminate infectious human rotaviruses and noroviruses from heat-inactivated viruses: applications of PMA/PMAxx, benzonase and RNase. AB - AIMS: Detection/Quantification of RNA viruses is mostly done by reverse transcriptase (RT)-(q)PCR, but it does not distinguish between infectious and noninfectious viruses. Our aim was to test, how different pretreatments before RT qPCR could eliminate positivity originated from external nucleic acids or genomes of damaged particles. METHODS AND RESULTS: Heat-inactivated (80 degrees C for 10 min) rotavirus Wa strain and faecal samples containing rotavirus or norovirus were treated with PMA/PMAxx, benzonase or crude extract RNase prior to RT-qPCR. PMA/PMAxx pretreatments were not consistently efficient for RV, although they seemed to work to some extent for heat-inactivated norovirus. Benzonase and RNase provided consistently 2.2-2.8 log10 reductions in the titre of faecal rotavirus. CONCLUSIONS: All pretreatments need to be further validated for each virus separately, taking into account sample matrix and inactivation conditions. Although none of the pretreatments could completely render inactivated viruses undetectable, RNase worked most consistently for both rota- and norovirus. SIGNIFICANCE AND IMPACT OF THE STUDY: This study sheds light on capacity of the most common pre-RT-qPCR treatments to eliminate damaged, noninfectious rotaviruses and noroviruses after thermal treatment. To our knowledge, this is the first time, when benzonase has been used in this context. PMID- 29464826 TI - International Continence Society supported pelvic physiotherapy education guideline. AB - AIM: To provide a guideline of desired knowledge, clinical skills and education levels in Pelvic Physiotherapy (PT). Physiotherapy (PT) involves "using knowledge and skills unique to physiotherapists" and, "is the service only provided by, or under the direction and supervision of a physiotherapist."1 METHODS: The PT Committee, within the body of the International Continence Society (ICS), collected information regarding existing educational levels for pelvic floor PT. Through face to face and on on-line discussion consensus was reached which was summarized in three progressive educational levels based on knowledge and skills and brought together in a guideline. The guideline was submitted to all physiotherapists and the Educational Committee of the ICS, and after approval, submitted to the Executive Board of the ICS. RESULT: The guideline lists, in a progressive way, knowledge areas and skills to be achieved by education. It is broad and allows for individual interpretation based on local situations regarding education and healthcare possibilities. It is intended to be dynamic and updated on a regular basis. CONCLUSION: The proposed Pelvic PT education guideline is a dynamic document that allows course creators to plan topics for continuing course work and to recognize educational level of a therapist in the field of Pelvic PT. This education guideline can be used to set minimum worldwide standards resulting in higher skill levels for local pelvic physiotherapists and thereby better patient care outcome. PMID- 29464827 TI - Keep your feet warm? A cryptic refugium of trees linked to a geothermal spring in an ocean of glaciers. AB - Up to now, the most widely accepted idea of the periglacial environment is that of treeless ecosystems such as the arctic or the alpine tundra, also called the tabula rasa paradigm. However, several palaeoecological studies have recently challenged this idea, that is, treeless environments in periglacial areas where all organisms would have been exterminated near the glacier formed during the Last Glacial Maximum, notably in the Scandinavian mountains. In the Alps, the issue of glacial refugia of trees remains unanswered. Advances in glacier reconstructions show that ice domes did not cover all upper massifs, but glaciers filled valleys. Here, we used fossils of plant and malacofauna from a travertine formation located in a high mountain region to demonstrate that trees (Pinus, Betula) grew with grasses during the Lateglacial-Holocene transition, while the glacier fronts were 200-300 m lower. The geothermal travertine started to accumulate more than 14,500 years ago, but became progressively more meteogene about 11,500 years ago due to a change in groundwater circulation. With trees, land snails (gastropods) associated to woody or open habitats and aquatic mollusc were also present at the onset of the current interglacial, namely the Holocene. The geothermal spring, due to warm water and soil, probably favoured woody glacial ecosystems. This new finding of early tree growth, combined with other scattered proofs of the tree presence before 11,000 years ago in the western Alps, changes our view of the tree distribution in periglacial environments, supporting the notion of tree refugia on nunataks in an ocean of glaciers. Therefore, the tabula rasa paradigm must be revisited because it has important consequences on the global changes, including postglacial plant migrations and biogeochemical cycles. PMID- 29464829 TI - Clinical judgement in precision medicine. AB - Precision medicine, which aims to individualize care based upon the unique combination of genetic, environmental, and lifestyle features in particular patients, will require an evolution in clinical decision making. Practitioners of precision medicine will need to utilize an expanded body of medical knowledge derived from a wide variety of sources. Clinical judgement in the case-based reasoning necessary for individualizing care will involve understanding and utilizing methodological approaches not commonly invoked in medicine, including mechanistic and qualitative research results. Instead of searching for an answer in the published literature, precision medicine demands clinical judgement that finds the reasons for clinical decisions within, not without, the patient. PMID- 29464828 TI - Significance of tumor-infiltrating lymphocytes before and after neoadjuvant therapy for rectal cancer. AB - Neoadjuvant therapy for locally advanced rectal cancer is becoming increasingly common. However, biomarkers predicting the response to neoadjuvant therapy have not been established. Tumor-infiltrating lymphocytes (TILs) have a crucial effect on tumor progression and survival outcome as the primary host immune response, and an antitumor immune effect has been reported to contribute to the response to radiotherapy and chemotherapy. We investigated the significance of TILs before and after neoadjuvant treatment and the change in the density of those TILs. Sixty-four patients who underwent radical resection after neoadjuvant treatment for locally advanced rectal cancer were enrolled. The number of TIL subsets was examined using immunohistochemical staining of pretreatment biopsy samples and post-treatment resected specimens. In both the neoadjuvant chemotherapy cohort and the neoadjuvant chemoradiotherapy cohort, a low density of CD8+ TILs in pretreatment biopsy samples was associated with a poor response, and a low density of CD8+ TILs in post-treatment resected specimens was similarly associated with a poor response. In the neoadjuvant chemoradiotherapy cohort, the density of CD8+ TILs in post-treatment resected specimens was significantly increased compared with that in pretreatment biopsy samples. We concluded that T lymphocyte-mediated immune reactions play an important role in tumor response to neoadjuvant treatment for rectal cancer, and the evaluation of TILs in pretreatment biopsy samples might be a predictor of the clinical effectiveness of neoadjuvant treatment. Furthermore, neoadjuvant therapy, especially chemoradiotherapy, could induce the activation of the local immune status. PMID- 29464830 TI - Dietary Approach to Stop Hypertension (DASH) diet and risk of renal function decline and all-cause mortality in renal transplant recipients. AB - Renal transplant recipients (RTR) are at risk of decline of graft function and premature mortality, with high blood pressure as an important risk factor for both. To study the association of the Dietary Approach to Stop Hypertension (DASH) diet with these adverse events, we conducted a prospective cohort study of adult RTR. Dietary data were collected using a validated 177-item food frequency questionnaire and an overall DASH-score was obtained. We included 632 stable RTR (mean +/- standard deviation age 53.0 +/- 12.7 years, 57% men). Mean DASH score was 23.8 +/- 4.7. During median follow-up of 5.3 (interquartile range, 4.1-6.0) years, 119 (18.8%) RTR had renal function decline, defined as a combined endpoint of doubling of serum creatinine and death-censored graft failure, and 128 (20.3%) died. In Cox-regression analyses, RTR in the highest tertile of the DASH score had lower risk of both renal function decline (hazard ratio [HR] = 0.57; 95% confidence interval [CI], 0.33-0.96, P = .03) and all-cause mortality (HR = 0.52; 95%CI, 0.32-0.83, P = .006) compared to the lowest tertile, independent of potential confounders. Adherence to a DASH-style diet is associated with lower risk of both renal function decline and all-cause mortality. These results suggest that a healthful diet might benefit long-term outcome in RTR. PMID- 29464831 TI - Intensive remote monitoring versus conventional care in type 1 diabetes: A randomized controlled trial. AB - OBJECTIVE: While frequent contact with diabetes care providers may improve glycemic control among patients with type 1 diabetes (T1D), in-person visits are labor-intensive and costly. This study was conducted to assess the impact of an intensive remote therapy (IRT) intervention for pediatric patients with T1D. METHODS: Pediatric patients with T1D were randomized to IRT or conventional care (CC) for 6 months. Both cohorts continued routine quarterly clinic visits and uploaded device data; for the IRT cohort, data were reviewed and patients were contacted if regimen adjustments were indicated. Glycated hemoglobin (HbA1c) change from baseline was assessed at 6 and 9 months. Diabetes-related quality of life (QoL), healthcare services utilization, and hypoglycemic events were also tracked. RESULTS: Among 117 enrollees (60 IRT, 57 CC), mean (SD) 6-month %HbA1c change for IRT vs CC was -0.34 (0.85) (-3.7 mmol/mol) vs -0.05 (0.74) (-0.5 mmol/mol) overall (P = .071); -0.15 (0.67) (1.6 mmol/mol) vs -0.02 (0.66) (0.2 mmol/mol) for ages 8 to 12 (P = .541); and -0.50 (0.95) (-5.5 mmol/mol) vs -0.06 (0.80) (-0.7 mmol/mol) for ages 13 to 17 (P = .056). Diabetes-related QoL increased by 6.5 and 1.3 points for IRT and CC, respectively (P = .062). Three months after intervention cessation, %HbA1c changed minimally among treated children aged 8 to 12 but increased by 0.22 (0.89) (2.4 mmol/mol) among those aged 13 to 17. CONCLUSIONS: IRT substantially affected diabetes metrics and improved QoL among pediatric patients with T1D. Adolescents experienced a stronger treatment effect, but had difficulty in sustaining improved control after intervention cessation. PMID- 29464833 TI - CgPDR1 gain-of-function mutations lead to azole-resistance and increased adhesion in clinical Candida glabrata strains. AB - Recently, Candida glabrata has emerged as a health-threatening pathogen and the rising resistance to antifungal agent in C. glabrata often leads to clinical treatment failure. To investigate the evolution of drug resistance and adherence ability in four paired clinical isolates collected before and after antifungal treatment. Sequence analysis, gene disruption, drug-susceptibility, adhesion tests and real-time quantitative PCR were performed. The azole-susceptible strains acquired azole resistance after antifungal therapy. Four gain-of-function (GOF) mutations in CgPDR1 were revealed by sequence analysis, namely G1099D, G346D, L344S and P927S, the last being reported for the first time. CDR1, CDR2 and SNQ2 efflux pump gene expression levels were elevated in strains harbouring GOF mutations in CgPDR1, resulting in decreased azole susceptibility. CgPDR1 alleles with distinct GOF mutations displayed different expression profiles for the drug-related genes. CgPDR1GOF mutations led to increased efflux pumps expression levels in a strain background independent way. Hyperactive Pdr1G1099D and Pdr1P927S displayed strain background-dependent increased adherence to host cells via upregulation of EPA1 transcription. Interestingly, the drug transporter gene expression levels did not always correspond with that of the adhesin EPA1 gene. GOF mutations in CgPDR1 conferred drug resistance and increased adherence in the clinical strains, possibly endowing C. glabrata with increased viability and pathogenicity. PMID- 29464834 TI - Increasing incidence of HIV- associated tuberculosis in Romanian injecting drug users. AB - BACKGROUND: A high prevalence of tuberculosis (TB) among HIV-positive injecting drug users (IDUs) may fuel the TB epidemic in the general population of Romania. We determined the frequency and characteristics of TB in HIV-infected IDUs referred to a national centre. METHODS: Prospective observational cohort study of all newly-diagnosed HIV-positive IDUs admitted to Victor Babes Hospital, Bucharest, between January 2009 and December 2014. Socio-demographics, clinical characteristics and outcomes of HIV/TB co-infected IDUs were compared to HIV positive IDUs without TB. RESULTS: 170/598 (28.5%) HIV-infected IDUs were diagnosed with TB. The prevalence increased from 12.5% in 2009 to 32.1% in 2014 (P < 0.001). HIV/TB co-infected individuals had lower median CD4 cell counts 75 (vs. 450/mm3 , P < 0.0001) and higher median HIV viral loads 5.6 log10 (vs. 4.9 log10 , P < 0.0001) when presenting to healthcare services. 103/170 (60.6%) HIV/TB co-infected IDUs were diagnosed with pulmonary TB. Resistant Mycobacterium tuberculosis strains were common, with 18/105 (17.1%) of patients having Multi Drug Resistant (MDR) disease. Higher mortality rate was associated with TB co infection (P < 0.0001), extra-pulmonary TB (P = 0.0026) and extensively drug resistant TB (P = 0.024). CONCLUSIONS: Tuberculosis (TB) is an increasing problem in HIV-infected IDUs in Romania. Presentation is often with advanced HIV, significant TB drug resistance and consequent outcomes are poor. PMID- 29464832 TI - Differential effects of donor-specific HLA antibodies in living versus deceased donor transplant. AB - The presence of donor-specific anti-HLA antibodies (DSAs) is associated with increased risk of graft failure after kidney transplant. We hypothesized that DSAs against HLA class I, class II, or both classes indicate a different risk for graft loss between deceased and living donor transplant. In this study, we investigated the impact of pretransplant DSAs, by using single antigen bead assays, on long-term graft survival in 3237 deceased and 1487 living donor kidney transplants with a negative complement-dependent crossmatch. In living donor transplants, we found a limited effect on graft survival of DSAs against class I or II antigens after transplant. Class I and II DSAs combined resulted in decreased 10-year graft survival (84% to 75%). In contrast, after deceased donor transplant, patients with class I or class II DSAs had a 10-year graft survival of 59% and 60%, respectively, both significantly lower than the survival for patients without DSAs (76%). The combination of class I and II DSAs resulted in a 10-year survival of 54% in deceased donor transplants. In conclusion, class I and II DSAs are a clear risk factor for graft loss in deceased donor transplants, while in living donor transplants, class I and II DSAs seem to be associated with an increased risk for graft failure, but this could not be assessed due to their low prevalence. PMID- 29464835 TI - Perceived utility and relevance of intern well-being sessions. AB - BACKGROUND/AIM: We conducted a pilot project assessing the perceived utility and relevance of well-being sessions provided to interns at a large regional teaching hospital in Australia, with the aim of promoting intern well-being and fostering a nurturing and supportive learning and work hospital culture. METHODS: Our intervention involved two separate 60-min lectures covering well-being topics and skills to approximately 50 interns within protected teaching time, along with emailed well-being resources. Participants were emailed an online survey asking questions about value and novelty of the sessions, and work satisfaction and stress, as well as open comments. A request for an additional interview to explore responses in more depth was included. RESULTS: Fifty interns attended at least one of the sessions and 35 participated in the survey, six to an additional interview. Survey and interview data showed that the majority of interns perceived the sessions as valuable, relevant and useful and felt that ongoing sessions would benefit junior medical officers in future years. Feedback highlighted the importance of providing future sessions in person, incorporating an interactive approach and emphasised that work site factors and medical culture play a large causative role in their stress. CONCLUSIONS: We conclude that well being sessions are acceptable and useful to interns and should be incorporated into hospital teaching curricula, and evaluated. However, these programmes are unlikely to change the high stress experienced unless external and systemic stressors are addressed by all stakeholders. PMID- 29464836 TI - The presentation and management of platelet disorders in pregnancy. AB - Thrombocytopenia, defined as a platelet count less than 150 000 per microlitre, occurs in 7%-12% of all pregnancies. Apart from anaemia, it is the most common haematological disorder in pregnancy. Despite its frequent occurrence, thrombocytopenia often leads to difficulties of diagnosis and management in pregnancy. Typically, a pregnant woman will have platelet counts of 150 000 to 450 000 per microlitre and platelet counts may be slightly lower than those of healthy, non-pregnant controls. Approximately, 8% of pregnant women will develop mild thrombocytopenia (100 000-150 000 per microlitre) and while 65% of these women will have no underlying pathology, all pregnant women with platelet counts of less than 100 000 per microlitre should undergo further clinical and laboratory assessment. Thrombocytopenia in pregnancy occurs as a result of multiple distinct conditions, we present four cases of thrombocytopenia in pregnancy encountered in our unit over a 12-month period. These include gestational thrombocytopenia, immune thrombocytopenic purpura (ITP), thrombotic thrombocytopenic purpura (TTP) and thrombocytopenia absent radius (TAR) syndrome. The literature review of these cases highlights the significance of identification, understanding pathophysiology and a multidisciplinary approach to these conditions. We refresh knowledge on these conditions and emphasise the importance of thrombocytopenia in pregnancy.

AB - According to the Banff criteria for kidney allografts, isolated vascular or "v" lesions are defined as intimal inflammation, age-inappropriate fibro-intimal hyperplasia, or both, without the presence of associated interstitial T cell mediated rejection (TCMR). In general, these lesions portend a worse outcome for kidney allografts, particularly in those where the "v" lesions are identified in patients with coexistent donor specific antibodies (DSA) or later after transplantation. Although affected arteries are rarely sampled in liver allograft biopsies, we identified nine patients at a mean of 1805 days posttransplantation and compared these to matched controls. Almost half (4 of 9) of the study patient biopsies showed inflammatory arteritis associated with focal or diffuse C4d positivity, which was not observed in matched controls. One "v" lesion patient progressed to rejection-related graft failure and two developed moderate/severe TCMR in subsequent biopsies, whereas only one rejection episode occurred in follow-up biopsies, and no rejection-related deaths or graft failures were detected in controls. In conclusion, patients with liver allograft isolated "v" lesions should undergo further evaluation and closer follow-up for impending TCMR and/or underlying co-existent chronic antibody-mediated rejection (AMR). PMID- 29464838 TI - Transformation/dissolution characterization of tungsten and tungsten compounds for aquatic hazard classification. AB - The transformation/dissolution protocol (T/DP) for metals and sparingly soluble metal compounds was applied to determine the transformation/dissolution (T/D) characteristics of yellow tungsten trioxide, WO3 ; blue tungsten oxide, WOx, x taken as 2.9; tungsten disulphide, WS2 ; tungsten metal, W; 3 samples of tungsten carbide, WC; sodium tungstate, Na2 WO4 . 2H2 O; ammonium paratungstate (APT), (NH4 )10 (H2 W12 O42 ) . 4H2 O; and ammonium metatungstate (AMT) (NH4 )6 (H2 W12 O40 ) . 3H2 O. The T/D data were used to derive aquatic hazard classification outcomes under the United Nations Globally Harmonized System of Classification and Labelling of Chemicals (UN GHS) and European Union Classification, Labelling and Packaging of Substances and Mixtures (EU CLP) schemes by comparing the data with selected acute and chronic ecotoxicity reference values (ERVs) of 31 and 3.37 mg W/L, respectively. In addition to the concentration of total dissolved tungsten (W), the T/D solutions were analyzed for the concentration of the tungstate anion, because speciation can be an important factor in establishing the ecotoxicity of dissolved metals. Results show that the tungstate anion was the predominant W-bearing species in solution for all substances examined at pH 6 and 8.5. It was found that the 100 mg/L loadings of both the yellow WO3 and the blue WOx exceeded the 31 mg/L acute ERV, so they would classify as Acute 3 Chronic 3 under the UN GHS scheme but they would not classify under the EU CLP. An effect of pH on the reactivity of the W metal was observed with 3% and 16% W dissolution at pH 6 and 8.5, respectively. Tungsten metal would not classify under either the UN GHS or EU CLP schemes nor would the WS2 . The WCs were the least reactive in terms of the 1% or less dissolution of the contained W at pH 6. A critical surface area for WC was calculated. The sodium tungstate, APT and the AMT all yielded, at pH 8.5, total dissolved W concentrations that would result in UN GHS Acute 3-Chronic 3 classifications.

AB - The active species in supported metal catalysts are elusive to identify, and large quantities of inert species can cause significant waste. Herein, using a stoichiometrically precise synthetic method, we prepare atomically dispersed palladium-cerium oxide (Pd1 /CeO2 ) and hexapalladium cluster-cerium oxide (Pd6 /CeO2 ), as confirmed by spherical-aberration-corrected transmission electron microscopy and X-ray absorption fine structure spectroscopy. For aerobic alcohol oxidation, Pd1 /CeO2 shows extremely high catalytic activity with a TOF of 6739 h 1 and satisfactory selectivity (almost 100 % for benzaldehyde), while Pd6 /CeO2 is inactive, indicating that the true active species are single Pd atoms. Theoretical simulations reveal that the bulkier Pd6 clusters hinder the interactions between hydroxy groups and the CeO2 surface, thus suppressing synergy of Pd-Ce perimeter. PMID- 29464840 TI - Distribution and density of melatonin receptors in human main pancreatic islet cell types. AB - Recent investigations of our group established that melatonin modulates hormone secretion of pancreatic islets via melatonin receptor types MT1 and MT2. Expression of MT1 and MT2 has been shown in mouse, rat, and human pancreatic islets as well as in the beta-, alpha-, and delta-cell lines INS-1, alphaTC1.9, and QGP-1. In view of these earlier investigations, this study was performed to analyze in detail the distribution and density of melatonin receptors on the main islet cell types in human pancreatic tissue obtained from nondiabetic and type 2 diabetic patients. Immunohistochemical analysis established the presence of MT1 and MT2 in beta-, alpha-, and delta-cells, but notably, with differences in receptor density. In general, the lowest MT1 and MT2 receptor density was measured in alpha-cells compared to the 2 other cell types. In type 2 diabetic islets, MT1 and MT2 receptor density was increased in delta-cells compared to normoglycemic controls. In human islets in batch culture of a nondiabetic donor, an increase of somatostatin secretion was observed under melatonin treatment while in islets of a type 2 diabetic donor, an inhibitory influence could be observed, especially in the presence of 5.5 mmol/L glucose. These data suggest the following: i) cell-type-specific density of MT1 and MT2 receptors in human pancreatic islets, which should be considered in context of the hormone secretion of islets, ii) the influence of diabetes on density of MT1 and MT2 as well as iii) the differential impact of melatonin on somatostatin secretion of nondiabetic and type 2 diabetic islets. PMID- 29464841 TI - Super-Chelators for Advanced Protein Labeling in Living Cells. AB - Live-cell labeling, super-resolution microscopy, single-molecule applications, protein localization, or chemically induced assembly are emerging approaches, which require specific and very small interaction pairs. The minimal disturbance of protein function is essential to derive unbiased insights into cellular processes. Herein, we define a new class of hexavalent N-nitrilotriacetic acid (hexaNTA) chelators, displaying the highest affinity and stability of all NTA based small interaction pairs described so far. Coupled to bright organic fluorophores with fine-tuned photophysical properties, the super-chelator probes were delivered into human cells by chemically gated nanopores. These super chelators permit kinetic profiling, multiplexed labeling of His6 - and His12 tagged proteins as well as single-molecule-based super-resolution imaging.

AB - It still remains to be demonstrated that using molecular profiling to guide therapy improves patient outcome in oncology. Classification of somatic variants is not straightforward, rendering treatment decisions based on variants with unknown significance (VUS) hard to implement. The oncogenic activity of VUS and mutations identified in 12 patients treated with molecularly targeted agents (MTAs) in the frame of SHIVA01 trial was assessed using Functional Annotation for Cancer Treatment (FACT). MTA response prediction was measured in vitro, blinded to the actual clinical trial results, and survival predictions according to FACT were correlated with the actual PFS of SHIVA01 patients. Patients with positive prediction had a median PFS of 5.8 months versus 1.7 months in patients with negative prediction (P < 0.05). Our results highlight the role of the functional interpretation of molecular profiles to predict MTA response. PMID- 29464844 TI - Dietary live yeast and increased water temperature influence the gut microbiota of rainbow trout. AB - AIMS: The objective was to determine the effects of dietary substitution of fishmeal (FM) with live yeast and increasing water temperature on the diversity and composition of gut microbiota in rainbow trout. METHODS AND RESULTS: Fish were fed either FM or yeast (Saccharomyces cerevisiae) and reared in water temperatures of either 11 degrees C (cold) or 18 degrees C (warm) for 6 weeks. Luminal content and mucosa were collected from the distal gut and the load, diversity and species abundance of yeast and bacteria were analysed using agar plating, MALDI-TOF and rRNA gene amplicon sequencing. Yeast in the gut of fish fed FM were represented by S. cerevisiae, Rhodotorula spp. and Debaryomyces hansenii, while fish fed yeast contained 4-5 log higher CFU per g of yeast that were entirely represented by S. cerevisiae. For gut bacteria, sequencing of 16S rRNA gene amplicons using Illumina MiSeq showed lower bacterial diversity and abundance of lactic acid bacteria, especially Lactobacillus, in fish reared in warm rather than cold water. Fish fed yeast had similar bacterial diversity and lower abundance of Leuconostocaceae and Photobacterium compared with fish fed FM. CONCLUSIONS: Feeding live yeast mainly increased yeast load in the gut, while increased water temperature significantly altered the gut microbiota of rainbow trout in terms of bacterial diversity and abundance. SIGNIFICANCE AND IMPACT OF THE STUDY: Live yeast can replace 40% of FM without disrupting bacteria communities in the gut of rainbow trout, while increased water temperature due to seasonal fluctuations and/or climate change may result in a gut dysbiosis that may jeopardize the health of farmed fish.

PMID- 29464846 TI - Real-life experience of a stent-less revascularization strategy using a combination of excimer laser and drug-coated balloon for patients with acute coronary syndrome. AB - OBJECTIVES: We aimed to test a novel stent-less revascularization strategy using a combination of excimer laser coronary angioplasty (ELCA) and drug-coated balloon (DCB) for patients with acute coronary syndrome (ACS). BACKGROUND: Percutaneous coronary intervention with drug eluting stents is a standard invasive treatment for ACS. Some unsolved issues however remain, such as stent thrombosis and bleeding risks associated with dual antiplatelet therapy. METHODS: Consecutive ACS patients were planned to receive either a DCB application following ELCA without a stent implantation or conventional revascularization with a coronary stent. The endpoints were (i) major cardiac adverse events (MACEs), defined as the composite of cardiac death, myocardial infarctions, and target lesion revascularization; (ii) target vessel revascularization (TVR); and (iii) angiographic outcome. RESULTS: Since a greater than expected number of patients allocated to the stent-less treatment arm eventually received a bailout stenting, the following 3 as-treated groups were compared; DCB with ELCA group (N = 60), Stent with ELCA group (N = 23), and Stent without ELCA group (N = 85). During a mean follow-up period of 420 +/- 137 days, and with angiographic 6- and 12-month-follow-up rates of 96.7%, 87%, and 81.2%, and 50%, 65.2%, and 45.9%, respectively, the MACE rate did not differ across the groups (10%, 4.3%, and 3.5%; P = 0.22) while an incidence of TVR was more common (15%, 0, and 4.7%; P = 0.02) and the diameter stenosis at 6-months of follow-up was greater (25.7 +/- 18.2, 14.9 +/- 13.1 and 16.2 +/- 15.4%; P = 0.002) in the DCB with ELCA group. CONCLUSIONS: The stent-less revascularization strategy with DCB and ELCA was associated with a higher occurrence of restenosis in ACS patients. PMID- 29464847 TI - Clinical efficacy of oral administration of finasteride at a dose of 2.5 mg/day in women with female pattern hair loss. AB - Female pattern hair loss (FPHL) presents with diffuse thinning over the mid frontal scalp, for which various treatment modalities have been tried. Although currently, oral 5 alpha-reductase inhibitors such as finasteride are being used, their clinical efficacy remains controversial. We retrospectively investigated 544 premenopausal or postmenopausal patients with FPHL who were prescribed finasteride at a dose of 2.5 mg/day. Our study excluded patients with a follow-up period of < 3 months and patients who were prescribed other FPHL treatment modalities including topical minoxidil. Finally, 112 patients were evaluated based on their medical records and clinical photographs. Based on assessment using the Ludwig scale at the time of their initial visit, among 112 patients studied, 59 patients were classified as belonging to grade I, 47 were grade II, and 6 were grade III. Using global photographs, we found that 33 (29.5%) of the 112 patients studied showed slight improvement, 73 (65.2%) showed significant improvement, whereas no change was recorded in 6 (5.4%). We could demonstrate efficacy of administration of finasteride at a dose of 2.5 mg/day for patients with FPHL and also found that finasteride has a better effect on hair growth when patients had a lower Ludwig score and an older age at onset. PMID- 29464848 TI - CORM-401 induces calcium signalling, NO increase and activation of pentose phosphate pathway in endothelial cells. AB - Carbon monoxide-releasing molecules (CO-RMs) induce nitric oxide (NO) release (which requires NADPH), and Ca2+ -dependent signalling; however, their contribution in mediating endothelial responses to CO-RMs is not clear. Here, we studied the effects of CO liberated from CORM-401 on NO production, calcium signalling and pentose phosphate pathway (PPP) activity in human endothelial cell line (EA.hy926). CORM-401 induced NO production and two types of calcium signalling: a peak-like calcium signal and a gradual increase in cytosolic calcium. CORM-401-induced peak-like calcium signal, originating from endoplasmic reticulum, was reduced by thapsigargin, a SERCA inhibitor, and by dantrolene, a ryanodine receptors (RyR) inhibitor. In contrast, the phospholipase C inhibitor U73122 did not significantly affect peak-like calcium signalling, but a slow and progressive CORM-401-induced increase in cytosolic calcium was dependent on store operated calcium entrance. CORM-401 augmented coupling of endoplasmic reticulum and plasmalemmal store-operated calcium channels. Interestingly, in the presence of NO synthase inhibitor (l-NAME) CORM-401-induced increases in NO and cytosolic calcium were both abrogated. CORM-401-induced calcium signalling was also inhibited by superoxide dismutase (poly(ethylene glycol)-SOD). Furthermore, CORM 401 accelerated PPP, increased NADPH concentration and decreased the ratio of reduced to oxidized glutathione (GSH/GSSG). Importantly, CORM-401-induced NO increase was inhibited by the PPP inhibitor 6-aminonicotinamide (6-AN), but neither by dantrolene nor by an inhibitor of large-conductance calcium-regulated potassium ion channel (paxilline). The results identify the primary role of CO induced NO increase in the regulation of endothelial calcium signalling, that may have important consequences in controlling endothelial function. PMID- 29464849 TI - In vitro protective effects of an aqueous extract of Clitoria ternatea L. flower against hydrogen peroxide-induced cytotoxicity and UV-induced mtDNA damage in human keratinocytes. AB - The traditional practice of eating the flowers of Clitoria ternatea L. or drinking their infusion as herbal tea in some of the Asian countries is believed to promote a younger skin complexion and defend against skin aging. This study was conducted to investigate the protective effect of C. ternatea flower water extract (CTW) against hydrogen peroxide-induced cytotoxicity and ultraviolet (UV) induced mitochondrial DNA (mtDNA) damage in human keratinocytes. The protective effect against hydrogen peroxide-induced cytotoxicity was determined by 3-(4, 5 dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium assay, and mtDNA damage induced by UV was determined by polymerase chain reaction. Preincubation of HaCaT with 100, 250, and 500 MUg/ml CTW reduced cytotoxicity effects of H2 O2 compared with control (H2 O2 alone). CTW also significantly reduced mtDNA damage in UV-exposed HaCaT (p < .05). CTW was chemically-characterized using high resolution liquid chromatography-mass spectrometry. The main compounds detected were assigned as anthocyanins derived from delphinidin, including polyacylated ternatins, and flavonol glycosides derived from quercetin and kaempferol. These results demonstrated the protective effects of C. ternatea flower extracts that contain polyacylated anthocyanins and flavonol glycosides as major constituents, against H2 O2 and UV-induced oxidative stress on skin cells, and may provide some explanation for the putative traditional and cosmetic uses of C. ternatea flower against skin aging. PMID- 29464850 TI - Reactions of Metal-Carbon Bonds within Six-Membered Metallaaromatic Rings. AB - Metallaaromatics represent a distinct and attractive class of heterocycles, which have greatly expanded the library of known aromatics. They have garnered extensive research interest on account of their unique properties, organometallic reactivity, and aromaticity. The metal-carbon bonds have been regarded as the most active reaction sites of metallaaromatics and a variety of related reactions have been demonstrated in the literature. This Minireview summarized recent findings on the reactivity of the metal-carbon bonds, mainly relevant to the representative metallaaromatics with six-membered ring scaffolds. A series of reactions occurred on the metal-carbon bonds, including the nucleophilic addition reactions, nucleophilic aromatic substitution reactions, electrophilic addition reactions, reactions with unsaturated compounds, and migratory insertion reactions, have been classified. These reactions demonstrate that the metal carbon bonds of metallaaromatics can undergo typical reactions for both aromatic species and metal carbene/carbyne complexes. Meanwhile, the reactivity trends of the metal-carbon bonds are strongly affected by the metal centers and the effect of the corresponding substituents of metallacycles. PMID- 29464851 TI - Alteration of GABAergic neurotransmission in Huntington's disease. AB - Hereditary Huntington's disease (HD) is characterized by cell dysfunction and death in the brain, leading to progressive cognitive, psychiatric, and motor impairments. Despite molecular and cellular descriptions of the effects of the HD mutation, no effective pharmacological treatment is yet available. In addition to well-established alterations of glutamatergic and dopaminergic neurotransmitter systems, it is becoming clear that the GABAergic systems are also impaired in HD. GABA is the major inhibitory neurotransmitter in the brain, and GABAergic neurotransmission has been postulated to be modified in many neurological and psychiatric diseases. In addition, GABAergic neurotransmission is the target of many drugs that are in wide clinical use. Here, we summarize data demonstrating the occurrence of alterations of GABAergic markers in the brain of HD carriers as well as in rodent models of the disease. In particular, we pinpoint HD-related changes in the expression of GABAA receptors (GABAA Rs). On the basis that a novel GABA pharmacology of GABAA Rs established with more selective drugs is emerging, we argue that clinical treatments acting specifically on GABAergic neurotransmission may be an appropriate strategy for improving symptoms linked to the HD mutation. PMID- 29464852 TI - Perceptions of driving after marijuana use compared to alcohol use among rural American young adults. AB - INTRODUCTION AND AIMS: Substance use contributes to motor vehicle crashes, the leading cause of death among young adults. The current qualitative study examined perceptions of the acceptability and harms associated with driving after marijuana versus alcohol use in rural America. Illuminating rural perspectives is critical given that the motor vehicle fatality rate is twice as high in rural as in urban areas in the USA. DESIGN AND METHODS: In 2015-2016, 72 young adults aged 18-25 years (Mage = 20.2; 50.7% female) living in Montana, USA, participated in 11 focus groups. A list of descriptive codes was generated inductively and two individuals coded participant comments. Discussion, memoing and concept mapping were used to uncover broader themes and transcripts were reviewed for evidence of these themes. RESULTS: There was shared consensus that, with regard to crash risk, driving after marijuana use was safer than driving after alcohol use. While alcohol was thought to impair driving ability universally, marijuana's impacts depended on individual characteristics (e.g. compensatory behaviours) and the marijuana itself (e.g. type). Participants expressed conflicting beliefs about policies surrounding marijuana use and driving but were more knowledgeable about alcohol-related policies. Participants viewed older adults and those in frontier areas as more disapproving of driving after marijuana use. DISCUSSION AND CONCLUSIONS: Misinformation about the consequences of driving after marijuana use is common, demonstrating the need for future research and educational interventions. Developing and disseminating guidelines for driving after marijuana use would help marijuana users make informed decisions and mitigate driving-related risks. PMID- 29464853 TI - Quality assessment of clinical practice guidelines for infectious diseases in China. AB - AIM: We aimed to appraise the quality of Chinese Society of Infectious Diseases of China Medical Association clinical practice guidelines (CPGs) for infectious diseases in China. METHODS: We performed the electronic search and hand search on the above-mentioned CPGs for infectious diseases published from January 1997 to October 2017. Each publication was evaluated using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument. RESULTS: Thirteen guidelines were identified and enrolled for the further evaluation. The median scores of the AGREE II domains across all 13 guidelines were as follows: scope and purpose 73.61% (36.11% to 84.72%), stakeholder involvement 12.50% (8.33% to 20.83%), rigor of development 19.27% (12.50% to 26.04%), clarity of presentation 86.11% (23.61% to 94.44%), applicability 33.33% (26.04% to 50.00%), and editorial independence 8.33% (4.17% to 16.67%). The clarity of presentation domain got the highest score among the six domains. Moreover, when compared the CPGs by the year of publication (2002 to 2006 vs. 2007 to 2017), the quality scores were higher in the CPGs published in the last 10 years than those published before, but with no significant difference. CONCLUSIONS: The quality score of CPGs for infectious diseases in China from January 1997 to October 2017 was moderate, but had significant shortcomings, especially in the stakeholder involvement and editorial independence domains. However, the AGREE II instrument is useful and feasible for appraising the CPGs and should be applied to develop, implement, and promote the CPGs in China. PMID- 29464855 TI - Luteoloside attenuates anoxia/reoxygenation-induced cardiomyocytes injury via mitochondrial pathway mediated by 14-3-3eta protein. AB - Ischemia/reperfusion (I/R) injury is the major cause of acute cardiovascular disease worldwide. 14-3-3eta protein has been demonstrated to protect myocardium against I/R injury. Luteoloside (Lut), a flavonoid found in many Chinese herbs, exerts myocardial protection effects. However, the mechanism remains unclear. We hypothesize that the cardioprotective role of Lut is exerted by regulating the 14 3-3eta signal pathway. To investigate our hypothesis, an in vitro I/R model was generated in H9C2 cardiomyocytes by anoxia/reoxygenation (A/R) treatment. The effects of Lut on cardiomyocytes with A/R injury were assessed by determining the cell viability, lactate dehydrogenase levels, intracellular reactive oxygen species levels, mitochondrial permeability transition pores (mPTP) openness, caspase-3 activity, and apoptosis rate. The effects on protein expression were tested using western blot analysis. Lut attenuated A/R-induced injury to cardiomyocytes by increasing the expression of 14-3-3eta protein and cell viability; decreasing levels of lactate dehydrogenase, reactive oxygen species, mPTP openness, caspase-3 activity, and low apoptosis rate were observed. However, the cardioprotective effects of Lut were blocked by AD14-3-3etaRNAi, an adenovirus knocking down the intracellular 14-3-3eta expression. In conclusion, to our knowledge, this is the first study to demonstrate that Lut protected cardiomyocytes from A/R-induced injury via the regulation of 14-3-3eta signaling pathway. PMID- 29464856 TI - Influence of chemoradiotherapy on nutritional status, functional capacity, quality of life and toxicity of treatment for patients with cervical cancer. AB - AIM: Assess the influence of chemoradiotherapy on the nutritional status, functional capacity and quality of life (QoL), associating these indicators at baseline with toxicity and interruption of oncologic treatment in women with cervical cancer. METHODS: Prospective cohort study performed on 49 women diagnosed with cervical cancer, who underwent treatment between August 2015 and January 2016. For data collection, two appointments were conducted by the lead researcher: the first occurred the day before the first chemotherapy session (T0) and the other at the end of chemotherapy session (T1). Nutritional status was measured by anthropometry (weight, height, mid-upper arm circumference and triceps skinfold thickness) and computed tomography (skeletal muscle index-SMI), functional capacity by handgrip strength (HGS) and Karnofsky Performance Status (KPS), and application of QoL questionnaire (EORTC QLQ-C30). RESULTS: The average age was 45 +/- 13.8 years and 81.6% of the women were diagnosed in stages II and III. There was significant reduction in HGS, KPS and QoL between T0 and T1, in addition to a significant QoL reduction according to worsening nutritional status. The interruption of chemotherapy was significantly associated with the variables of nutritional status assessed at baseline. Women who interrupted treatment due to acute toxicity also had a significant lower median SMI than those who concluded the treatment and 83% of these patients presented cachexia. CONCLUSIONS: Chemoradiotherapy treatment in patients with cervical cancer had changed negative nutritional parameters, function capacity and QoL, and poor nutritional status at baseline was associated with chemotherapy interruption. PMID- 29464858 TI - Effects of nurses' emotional intelligence on their organizational citizenship behavior, with mediating effects of leader trust and value congruence. AB - AIM: To investigate the causal relationship between nurses' emotional intelligence and their organizational citizenship behavior and the possible mediating effects of leader trust and value congruence. METHODS: The participants were 348 nurses who were working in a general hospital in a metropolitan area. The data were collected from December 16, 2012 to February 20, 2013. The hypothetical model of emotional intelligence, organizational citizenship behavior, leader trust, and value congruence was fitted to the actual data via structural equation modeling. RESULT: The leaders' emotional intelligence had a direct positive effect on leader trust and value congruence; however, the nurses' own emotional intelligence had a negative effect on these two variables. Furthermore, leader trust had a direct positive effect on organizational citizenship behavior; value congruence had no such relationship. The nurses' emotional intelligence had a partial, indirect effect on organizational citizenship behavior via leader trust. CONCLUSION: In a nursing organization, it is necessary to build a system, such as mentoring, to be able to exchange emotions actively among the members in order to enhance emotional intelligence and have the same values between leaders and members throughout open communication. Therefore, nurse managers can contribute greatly to the enhancement of organizational performance by promoting members' organizational citizenship behavior through improving their relationships with them and gaining their trust, while concurrently making efforts to further develop their emotional intelligence. PMID- 29464859 TI - Growth hormone-releasing peptide 6 prevents cutaneous hypertrophic scarring: early mechanistic data from a proteome study. AB - Hypertrophic scars (HTS) and keloids are forms of aberrant cutaneous healing with excessive extracellular matrix (ECM) deposition. Current therapies still fall short and cause undesired effects. We aimed to thoroughly evaluate the ability of growth hormone releasing peptide 6 (GHRP6) to both prevent and reverse cutaneous fibrosis and to acquire the earliest proteome data supporting GHRP6's acute impact on aesthetic wound healing. Two independent sets of experiments addressing prevention and reversion effects were conducted on the classic HTS model in rabbits. In the prevention approach, the wounds were assigned to topically receive GHRP6, triamcinolone acetonide (TA), or vehicle (1% sodium carboxy methylcellulose [CMC]) from day 1 to day 30 post-wounding. The reversion scheme was based on the infiltration of either GHRP6 or sterile saline in mature HTS for 4 consecutive weeks. The incidence and appearance of HTS were systematically monitored. The sub-epidermal fibrotic core area of HTS was ultrasonographically determined, and the scar elevation index was calculated on haematoxylin/eosin stained, microscopic digitised images. Tissue samples were collected for proteomics after 1 hour of HTS induction and treatment with either GHRP6 or vehicle. GHRP6 prevented the onset of HTS without the untoward reactions induced by the first-line treatment triamcinolone acetonide (TA); however, it failed to significantly reverse mature HTS. The preliminary proteomic study suggests that the anti-fibrotic preventing effect exerted by GHRP6 depends on different pathways involved in lipid metabolism, cytoskeleton arrangements, epidermal cells' differentiation, and ECM dynamics. These results enlighten the potential success of GHRP6 as one of the incoming alternatives for HTS prevention. PMID- 29464860 TI - Sensing of Vimentin mRNA in 2D and 3D Models of Wounded Skin Using DNA-Coated Gold Nanoparticles. AB - Wound healing is a highly complex biological process, which is accompanied by changes in cell phenotype, variations in protein expression, and the production of active biomolecules. Currently, the detection of proteins in cells is done by immunostaining where the proteins in fixed cells are detected by labeled antibodies. However, immunostaining cannot provide information about dynamic processes in living cells, within the whole tissue. Here, an easy method is presented to detect the transition of epithelial to mesenchymal cells during wound healing. The method employs DNA-coated gold nanoparticle fluorescent nanoprobes to sense the production of Vimentin mRNA expressed in mesenchymal cells. Fluorescence microscopy is used to achieve temporal detection of Vimentin mRNA in wounds. 3D light-sheet microscopy is utilized to observe the dynamic expression of Vimentin mRNA spatially around the wounded site in skin tissue. The use of DNA-gold nanoprobes to detect mRNA expression during wound healing opens up new possibilities for the study of real-time mechanisms in complex biological processes. PMID- 29464861 TI - Glioma infiltration and extracellular matrix: key players and modulators. AB - An outstanding characteristic of gliomas is their infiltration into brain parenchyma, a property that impairs complete surgical resection; consequently, these tumors might recur, resulting in a high mortality rate. Gliomas invade along preferential routes, such as those along white matter tracts and in the perineuronal and perivascular spaces. Brain extracellular components and their partners and modulators play a crucial role in glioma cell invasion. This review presents an extensive survey of the literature, showing how the brain extracellular matrix (ECM) is modulated during the glioma infiltration process. We explore aspects of ECM interaction with glioma cells, reviewing the main glycosaminoglycans, glycoproteins and proteoglycans. We discuss the roles of ECM binding proteins, including CD44, RHAMM, integrins and axonal guidance molecules, and highlight the role of proteases and glycosidases in glioma infiltration; in binding and release chemokines, cytokines and growth factors; and in generating new bioactive ECM fragments. We also consider the roles of cytoskeletal signaling, angiogenesis, miRNAs and the glial-to-mesenchymal transition linked to glioma invasion. We closely discuss therapeutic approaches based on the modulation of the extracellular matrix, targeting the control of glioma infiltration, its relative failure in clinical trials, and potential means to overcome this difficulty. PMID- 29464862 TI - Protein Network Analysis and Functional Studies of Calcium Oxalate Crystal Induced Cytotoxicity in Renal Tubular Epithelial Cells. AB - Our previous expression study has reported a set of proteins with altered levels in renal tubular cells after exposure to calcium oxalate monohydrate (COM) crystals, which are the main composition of kidney stones. However, their functional significance remained largely unknown. In this study, protein network analysis revealed that the significantly altered proteins induced by COM crystals were involved mainly in three main functional networks, including i) cell proliferation and wound healing; ii) oxidative stress and mitochondrial function; and iii) cellular junction complex and integrity. Cell proliferation and wound healing assays showed that the COM-treated cells had defective proliferation and tissue healing capability, respectively. Oxyblot analysis demonstrated accumulation of the oxidized proteins, whereas intracellular ATP level was significantly increased in the COM-treated cells. Additionally, level of zonula occludens-1 (ZO-1), a tight junction protein, was significantly decreased, consistent with the significant declines in transepithelial resistance (TER) and level of RhoA signaling molecule in the COM-treated cells. These findings indicate significant perturbations in mitochondrial and oxidative stress axis that cause defective cell proliferation, tissue healing capability, junctional protein complex, and cellular integrity of renal tubular epithelial cells exposed to COM crystals that may play important roles in kidney stone pathogenesis.

AB - AIM: Prescription of statins to patients with chronic liver disease whose alanine transaminase (ALT) is over three times the upper normal limit (UNL) is not recommended. In this study, we attempted to evaluate patients with baseline ALT levels > 3 * UNL who were prescribed statins without ethical problems, using electronic medical records. METHODS: We enrolled subjects with ALT levels > 3 * UNL. The patients were divided into three groups consisting of those who had been taking agents affecting liver function (HEPA) and continued to do so after the statin prescription (HepCon), those who had not previously taken HEPA and began doing so after statin prescription (HepNew), and those who had never taken HEPA (HepNo). All ALT levels were determined within 3 months of statins administration, and changes were monitored. RESULTS: From January 2009 to December 2012, 61 patients with baseline ALT levels > 3 * UNL were prescribed statins for the first time. During the 3-month ALT monitoring, levels of the HepCon, HepNew, and HepNo groups decreased by 45 +/- 8%, 64 +/- 10%, and 42 +/- 8%, respectively; however, intergroup differences were not significant (P = .386). All the subjects who were administered statins showed improvement or maintained their ALT levels, except for two subjects, which showed deterioration. However, the ALT levels of the two subjects subsequently remained stable. CONCLUSION: It is not clear whether it is safe to prescribe statins to patients with ALT > 3 times the UNL. Our study showed that prescription of statins in combination with HEPA did not cause deleterious effects, suggesting that ALT levels > 3 times the UNL do not have harmful effects.

PMID- 29464864 TI - Inferences of individual drug responses across diverse cancer types using a novel competing endogenous RNA network. AB - Differences in individual drug responses are an obstacle to progression in cancer treatment, and predicting responses would help to plan treatment. The accumulation of cancer molecular profiling and drug response data provides opportunities and challenges to identify novel molecular signatures and mechanisms of tumor responsiveness to drugs. This study evaluated drug responses with a competing endogenous RNA (ceRNA) system that depended on competition between diverse RNA species. We identified drug response-related ceRNA (DRCEs) by combining the sequence and expression data of long noncoding RNA (lncRNA), microRNA (miRNA), and messenger RNA (mRNA), and the survival data of cancer patients treated with drugs. We constructed a patient-drug two-layer integrated network and used a linear weighting method to predict individual drug responses. DRCEs were found to be significantly enriched in known cancer and drug-associated data resources, involved in biological processes known to mediate drug responses, and correlated to drug activity in cancer cell lines. The dysregulation of DRCE expression influenced drug response-associated functions and pathways, suggesting DRCEs as potential therapeutic targets affecting drug responses. A further case study in breast invasive carcinoma (BRCA) found that DRCE expression was consistent with the drug response pattern and the aberrant expression of the two NEAT1-related DRCEs may lead to poor response to tamoxifen therapy for patients with TP53 mutations. In summary, this study provides a framework for ceRNA-based evaluation of clinical drug responses across multiple cancer types. Understanding the underlying molecular mechanisms of drug responses will allow improved response to chemotherapy and outcomes of cancer treatment.

There have been no reported cases, however, of a biliary stricture secondary to a migrated suture after laparoscopic distal gastrectomy (LDG). Here, we report one such case. The patient was a 60-year-old man who underwent LDG with Roux-en-Y reconstruction for early gastric cancer. Pathology revealed early cancer (T1N0M0) with a curative resection. Two years after LDG, the patient was found to have elevated hepatobiliary enzymes. After further workup, the new diagnosis was invasive cholangiocarcinoma (T2N0M0), and the patient underwent pancreaticoduodenectomy. Intraoperatively, a monofilament nylon suture was found in the center of a biliary stricture; this suture was previously used for duodenal closure during LDG. Histologically, the bile duct with stricture showed chronic inflammation and fibrosis. Despite no evidence of invasive carcinoma on pathology, a small lesion of adenocarcinoma in situ was found in the superior common hepatic duct. PMID- 29464867 TI - Blunted cortisol response to stress in patients with eating disorders: Its association to bulimic features. AB - OBJECTIVE: Clinical research on cortisol response to stress in patients with eating disorders has provided controversial and even contradictory results. As this might be the consequence of the inclusion in the studies of heterogeneous clinical populations, 3 highly selected samples were studied. METHODS: Dexamethasone suppression test was performed on 15 restricting anorexia nervosa patients without history of bulimia nervosa (BN), 17 BN patients with normal weight and no history of anorexia nervosa, and 22 healthy controls. Three days later, the Trier Social Stress Test was applied, and 8 saliva samples were collected along the trial for cortisol assessment. RESULTS: When the patients were considered as a single group, a slightly blunted cortisol response to stress was observed, but when the 3 groups were considered separately, the blunted response was observed only in the BN patients. DISCUSSION: The results support the association between blunted cortisol response and bulimic features. PMID- 29464868 TI - An improved strategy for skin lesion detection and classification using uniform segmentation and feature selection based approach. AB - Melanoma is the deadliest type of skin cancer with highest mortality rate. However, the annihilation in early stage implies a high survival rate therefore, it demands early diagnosis. The accustomed diagnosis methods are costly and cumbersome due to the involvement of experienced experts as well as the requirements for highly equipped environment. The recent advancements in computerized solutions for these diagnoses are highly promising with improved accuracy and efficiency. In this article, we proposed a method for the classification of melanoma and benign skin lesions. Our approach integrates preprocessing, lesion segmentation, features extraction, features selection, and classification. Preprocessing is executed in the context of hair removal by DullRazor, whereas lesion texture and color information are utilized to enhance the lesion contrast. In lesion segmentation, a hybrid technique has been implemented and results are fused using additive law of probability. Serial based method is applied subsequently that extracts and fuses the traits such as color, texture, and HOG (shape). The fused features are selected afterwards by implementing a novel Boltzman Entropy method. Finally, the selected features are classified by Support Vector Machine. The proposed method is evaluated on publically available data set PH2. Our approach has provided promising results of sensitivity 97.7%, specificity 96.7%, accuracy 97.5%, and F-score 97.5%, which are significantly better than the results of existing methods available on the same data set. The proposed method detects and classifies melanoma significantly good as compared to existing methods. PMID- 29464869 TI - Identification of the novel HLA-DQB1*06:209 allele in a Chinese individual.

AB - BACKGROUND: Primary hypothyroidism is a common endocrine disorder, more so in an increasing UK ageing population. There is no qualitative research examining the older patient perspective of symptoms, treatment and self-management of hypothyroidism. OBJECTIVE: In this study we explored the experience of hypothyroidism in older people and examined how this may influence their understanding and acceptance of diagnosis, treatment with Levothyroxine and the monitoring process. DESIGN: We conducted semi-structured interviews with 18 participants aged between 80 and 93 years. Interview transcripts were analysed using a thematic approach. RESULTS: The themes involved older individuals' knowledge about symptoms, confidence in diagnosis and understanding of clinical management regimen to understand hypothyroidism. Interpretation of the themes was informed by the Health Belief Model. CONCLUSION: Our findings can help to inform the development of interventions by treating clinicians and support staff to engage older patients in the long-term management of this chronic condition. PMID- 29464871 TI - Mining the Synergistic Core Allosteric Modules Variation and Sequencing Pharmacological Module Drivers in a Preclinical Model of Ischemia. AB - Identifying the variation of core modules and hubs seems to be critical for characterizing variable pharmacological mechanisms based on topological alteration of disease networks. We first identified a total of eight core modules by using an approach of multiple modular characteristic fusing (MMCF) from different targeted networks in ischemic mice. Interestingly, the value of module disturbance intensity (MDI) increased in drug combination group. Second, we redefined a weak allosteric module and a strong allosteric module. Then, we identified 15 pharmacological module drivers (PMDs) by leave-one-out screening with a cutoff of two folds, which were at least, in part, validated by expression and variation of topological contribution. Finally, we revealed the fusional and emergent variation of PMD in core modules contributing to multidimensional synergistic mechanism in ischemic mice and rats. Our findings provide a new set of drivers that might promote the pharmacological modular flexibility and offer a potential avenue for disease treatment. PMID- 29464872 TI - Time-dependent effect of phytocannabinoid treatments in fat cells. AB - The objectives of this paper is to investigate, demonstrate, and compare the mechanism of action of phytocannabinoids as antidiabetic and anti-obesity agents in preadipocytes and adipocytes, relative to rosiglitazone and metformin. Briefly, cannabis extract, Delta9 -tetrahydrocannabinol and cannabidiol (in very low dosages) were shown to promote glucose uptake higher or to equivalent levels, reduce fat accumulation, and reverse the insulin-resistant state of 3T3-L1 cells more effectively, relative to rosiglitazone and metformin. The phytocannabinoids had a more pronounced effect in preadipocytes undifferentiated model rather than the differentiated model. They induced a protective effect at the mitochondrial level by preventing overactivity of the succinate dehydrogenase pathway (p < .01), unlike rosiglitazone, through activation of the glycerol-3-phosphate dehydrogenase shuttling system. An increase in oxygen consumption and an increased expression of beta to alpha adrenoceptors (p < .05) in treated cells were noted. These findings contribute toward understanding the mechanism of action of phytocannabinoids in fat cells and highlight the antidiabetic and anti obesity properties of various phytocannabinoids that could potentially support the treatment of obesity-related insulin resistance. PMID- 29464873 TI - Improving the usefulness of a tool for appraising the quality of qualitative, quantitative and mixed methods studies, the Mixed Methods Appraisal Tool (MMAT). AB - RATIONALE, AIMS, AND OBJECTIVES: Systematic reviews combining qualitative, quantitative, and/or mixed methods studies are increasingly popular because of their potential for addressing complex interventions and phenomena, specifically for assessing and improving clinical practice. A major challenge encountered with this type of review is the appraisal of the quality of individual studies given the heterogeneity of the study designs. The Mixed Methods Appraisal Tool (MMAT) was developed to help overcome this challenge. The aim of this study was to explore the usefulness of the MMAT by seeking the views and experiences of researchers who have used it. METHODS: We conducted a qualitative descriptive study using semistructured interviews with MMAT users. A purposeful sample was drawn from the researchers who had previously contacted the developer of the MMAT, and those who have published a systematic review for which they had used the MMAT. All interviews were transcribed verbatim and analyzed by 2 coders using thematic analysis. RESULTS: Twenty participants from 8 countries were interviewed. Thirteen themes were identified and grouped into the 2 dimensions of usefulness, ie, utility and usability. The themes related to utility concerned the coverage, completeness, flexibility, and other utilities of the tool. Those regarding usability were related to the learnability, efficiency, satisfaction, and errors that could be made due to difficulties understanding or selecting the items to appraise. CONCLUSIONS: On the basis of the results of this study, we make several recommendations for improving the MMAT. This will contribute to greater usefulness of the MMAT. PMID- 29464875 TI - Probing lactate metabolism variations in large-scale bioreactors. AB - Lactate metabolism variations are frequently encountered in mammalian cell culture processes, especially during process scale-up. In this study, we took a multipronged approach to investigate the impact of pH, pCO2 , osmolality, base addition, and mixing conditions on the observed lactate variations in a Chinese Hamster Ovary (CHO) fed-batch process at 2,000 L scale. Two cultivating methods, CO2 -controlled and pH-controlled, were used to decouple the individual and synergistic effects from those factors. The individual effects from pH, pCO2 , and osmolality on lactate consumption/reproduction in the stationary phase were insignificant in the ranges studied though the initial lactate production rates varied. In contrast, lactate metabolism was found to be impacted by an interaction between mixing conditions and CO2 accumulation. High CO2 accumulation and poor mixing led to lactate reproduction, whereas either low CO2 or improved mixing were sufficient to result in lactate consumption. Base addition was not required for pH control in the low CO2 conditions, and therefore lactate reproduction was correlated with base addition under poor mixing conditions. Under good mixing conditions, CO2 -triggered base addition did not significantly impact lactate reproduction. It is reasonable to postulate that increased mixing times further promoted lactate production during base addition. As lactate reproduction results in more base addition to maintain pH, a cycle could be formed between lactate production and base addition. As a remediation, we showed that such lactate reproduction could be eliminated by improving CO2 removal at 2,000 L scale. (c) 2018 American Institute of Chemical Engineers Biotechnol.

AB - Patients with locally advanced rectal cancer (LARC) are at tremendous risk of metastatic diseases. To improve the prognoses of LARC patients, the efficacy of adding targeted agents to neoadjuvant therapy has been investigated by many researchers but remains controversial. A literature search of relevant databases was conducted through December 2016, 804 studies were identified and 32 investigations were ultimately included. A total of 1196 patients from 31 cohorts of 29 studies were eligible for quantitative synthesis in this single-arm setting meta-analysis. As pathologic complete response (pCR) shows promise as a prognosis indicator, we focused on pCR rates to evaluate whether adding targeted agents to neoadjuvant therapies improves the outcome of LARC patients. In our study, we revealed pooled estimates of pCR of 27% (95%CI, 21-34%) and 14% (95%CI, 9-21%) for bevacizumab-relevant cohorts and cetuximab-relevant cohorts, respectively. The safety of adding targeted agents to neoadjuvant therapy was also evaluated by pooling the data of Grade 3/4 toxicity. In conclusion, our study revealed that adding bevacizumab to the neoadjuvant therapy regimens provides appreciable pCR for LARC patients. Meanwhile, the efficacy of cetuximab remains inconclusive, RCTs with larger scale and better study design that stress more on mutational status are needed. PMID- 29464876 TI - Pilot towards developing a school mental health service: Experiences and lessons learnt in implementing Kenya integrated intervention model for dialogue and screening to promote children's mental well-being. AB - AIM: This paper aims at documenting the process of implementing "Kenya Integrated intervention model for Dialogue and Screening to promote children's mental wellbeing (KIDS)", with emphasis on activities, experiences, challenges and lessons learnt through the process that can inform improvement in Kenya and other social-economically and culturally similar settings. METHODS: KIDS aimed at providing early and integrated culturally acceptable intervention to promote child mental health in 6 to 13 year olds, targeting 5429 children in 24 schools. It was a pilot study conducted in 2 administrative counties in Kenya (Machakos and Makueni). The main goal of this study was to test the efficacy and feasibility of the proposed model that incorporated several significant stakeholders. RESULTS: The implementation of KIDS was grouped into 6 stepwise and 2 ongoing processes: (1) Stakeholder engagement and collaboration; (2) Selecting, adapting, translating, piloting and adopting the study tools; (3) Conducting Participatory Theory of Change (ToC); (4) Building the capacity of the key implementing partners; (5) Community awareness and psycho-education, (6) Using school-based life skills and peer clubs counselling to provide psychosocial support; (7) Ongoing monitoring, supervision and quality assurance and (8) Ongoing knowledge exchange and dissemination. Specific logistical challenges and possible solutions for future school mental health services are also stated in this article. CONCLUSION: KIDS is a feasible model for school mental health service programme in Kenya but there are challenges which provide innovative opportunities for better designed school mental health services programme. PMID- 29464877 TI - Patient navigation for lung cancer screening among current smokers in community health centers a randomized controlled trial. AB - Annual chest computed tomography (CT) can decrease lung cancer mortality in high risk individuals. Patient navigation improves cancer screening rates in underserved populations. Randomized controlled trial was conducted from February 2016 to January 2017 to evaluate the impact of a patient navigation program on lung cancer screening (LCS) among current smokers in five community health centers (CHCs) affiliated with an academic primary care network. We randomized 1200 smokers aged 55-77 years to intervention (n = 400) or usual care (n = 800). Navigators contacted patients to determine LCS eligibility, introduce shared decision making about screening, schedule appointments with primary care physicians (PCPs), and help overcome barriers to obtaining screening and follow up. Control patients received usual care. The main outcome was the proportion of patients who had any chest CT. Secondary outcomes were the proportion of patients contacted, proportion receiving LCS CTs, screening results and number of lung cancers diagnosed. Of the 400 intervention patients, 335 were contacted and 76 refused participation. Of the 259 participants, 124 (48%) were ineligible for screening; 119 had smoked <30 pack-years, and five had competing comorbidities. Among the 135 eligible participants in the intervention group, 124 (92%) had any chest CT performed. In intention-to-treat analyses, 124 intervention patients (31%) had any chest CT versus 138 control patients (17.3%, P < 0.001). LCS CTs were performed in 94 intervention patients (23.5%) versus 69 controls (8.6%, P < 0.001). A total of 20% of screened patients required follow-up. Lung cancer was diagnosed in eight intervention (2%) and four control (0.5%) patients. A patient navigation program implemented in CHCs significantly increased LCS among high risk current smokers. PMID- 29464878 TI - A blood tumor marker combination assay produces high sensitivity and specificity for cancer according to the natural history. AB - Diagnosis using a specific tumor marker is difficult because the sensitivity of this detection method is under 20%. Herein, a tumor marker combination assay, combining growth-related tumor marker and associated tumor marker (Cancer, 73(7), 1994), was employed. This double-blind tumor marker combination assay (TMCA) showed 87.5% sensitivity as the results, but a low specificity, ranging from 30 to 76%. To overcome this low specificity, we exploited complex markers, a multivariate analysis and serum fractionation by biochemical biopsy. Thus, in this study, a combination of new techniques was used to re-evaluate these serum samples. Three serum panels, containing 90, 120, and 97 samples were obtained from the Mayo Clinic. The final results showed 80-90% sensitivity, 84-85% specificity, and 83-88% accuracy. We demonstrated a notable tumor marker combination assay with high accuracy. This TMCA should be applicable for primary cancer detection and recurrence prevention. PMID- 29464879 TI - Insights into implementation of sacubitril/valsartan into clinical practice. AB - BACKGROUND: Sacubitril/valsartan significantly reduced heart failure hospitalization and mortality in PARADIGM-HF (Prospective Comparison of Angiotensin Receptor-Neprilysin Inhibitor With an Angiotensin-Converting Enzyme Inhibitor to Determine Impact on Global Mortality and Morbidity in Heart Failure). However, real-world data from its use are lacking. METHODS AND RESULTS: We retrospectively assessed all baseline and follow-up data of consecutive heart failure patients with reduced ejection fraction receiving therapy with sacubitril/valsartan for Class I recommendation between December 2016 and July 2017. Baseline characteristics and dose titration of sacubitril/valsartan were compared between patients in clinical practice and in PARADIGM-HF. A total of 120 patients (81% male) were switched from angiotensin-converting enzyme inhibitor or angiotensin receptor blocker to sacubitril/valsartan. A total of 20.1% of patients received dose uptitration. Patients were treated with an equipotential dose of renin-angiotensin system blockers before and after uptitration of sacubitril/valsartan (57 +/- 29% vs. 53 +/- 29% of target dose indicated by European Society of Cardiology guidelines; P = 0.286). However, they received a lower dose of sacubitril/valsartan in comparison with those in the PARADIGM-HF (219 +/- 12 vs. 375 +/- 75 mg; P < 0.001). In comparison with the patients receiving sacubitril/valsartan in PARADIGM-HF, patients in clinical practice were older and had a higher serum creatinine, higher New York Heart Association functional classification, and lower left ventricular ejection fraction (all P value <0.05). Even in comparison with patients who experienced dropout during the run-in phase of PARADIGM-HF, real-world patients exhibited baseline characteristics indicative of more disease severity. Patients were at high absolute baseline risk for adverse outcome as illustrated by the EMPHASIS-HF (Eplerenone in Mild Patients Hospitalization and Survival Study in Heart Failure) risk score of 6 (inter-quartile range 3), in comparison with 5 (inter-quartile range 4) in PARADIGM-HF. After initiation of sacubitril/valsartan, New York Heart Association class significantly improved (P < 0.001), but systolic blood pressure dropped more than was reported in PARADIGM-HF (7.1 +/- 8.0 vs. 3.2 +/- 0.4 mmHg; P < 0.001). CONCLUSIONS: Patients in clinical practice exhibit baseline characteristics associated with more severe disease, which might lead to prescription of lower doses. Nevertheless, patients in clinical practice are at high risk of adverse outcome as illustrated by the EMPHASIS-HF risk score, underscoring the large potential for sacubitril/valsartan therapy to reduce the risk of heart failure hospitalization and all-cause mortality. PMID- 29464880 TI - Spatial elongation of population receptive field profiles revealed by model-free fMRI back-projection. AB - Estimates of visual field topographies in human visual cortex obtained through fMRI traveling wave techniques usually provide the parameters of population receptive field (pRF) location (polar angle, eccentricity) and receptive field size. These parameters are obtained by fitting the recorded data to a standard model population receptive field. In this work, pRF profiles are measured directly by back-projecting preprocessed fMRI time-series to sweeps of a bar across the visual field in different angles. The current data suggest that the model-free pRF profiles contain information not only about receptive field location and size but also about the pRF shape characteristics. The elongation (ellipticity) of pRFs decreases along the early visual hierarchy to a different degree for the ventral and the dorsal stream. Furthermore, ellipticity changes as a function of eccentricity. pRF orientation shows a high degree of collinearity with its angular position within the visual field. Using model-free pRF measurements, the traveling wave technique provides additional characteristics of pRF topographies that are not restricted to size and provide robust measures within the single subject. PMID- 29464881 TI - Cytologic features of needle aspiration of ovarian sex cord tumor with annular tubules: Report of two cases and literature review. AB - Sex cord tumor with annular tubules (SCTAT) is a rare ovarian tumor with characteristic microscopic morphologic features. Diagnosis most often is based on examination of tissue specimens. Cytologic features of this tumor rarely have been described in the English literature. Herein, we report cytologic findings of cyst aspiration fluid in two cases of SCTAT, with cyto-histologic correlation. PMID- 29464882 TI - Designed Precursor for the Controlled Synthesis of Highly Active Atomic and Sub nanometric Platinum Catalysts on Mesoporous Silica. AB - The development of new methods to synthesize nanometric metal catalysts has always been an important and prerequisite step in advanced catalysis. Herein, we design a stable nitrogen ligated Pt complex for the straightforward synthesis by carbonization of uniformly sized atomic and sub-nanometric Pt catalysts supported on mesoporous silica. During the carbonization of the Pt precursor into active Pt species, the nitrogen-containing ligand directed the decomposition in a controlled fashion to maintain uniform sizes of the Pt species. The nitrogen ligand had a key role to stabilize the single Pt atoms on a weak anchoring support like silica. The Pt catalysts exhibited remarkable activities in the hydrogenation of common organic functional groups with turnover frequencies higher than in previous studies. By a simple post-synthetic treatment, we could selectively remove the Pt nanoparticles to obtain a mixture of single atoms and nanoclusters, extending the applicability of the present method. PMID- 29464883 TI - High-intensity interval training improves acute plasma volume responses to exercise that is age dependent. AB - Plasma volume (PV) is affected by several factors including age, physical training and, acutely, by exercise intensity. The purpose of this study was to investigate the effects of 6 weeks of high-intensity interval training (HIT) on PV and blood pressure (BP) changes among sedentary individuals. Thirty subjects aged between 18 and 71 years [body mass index=30.1(1.2) kg/m2 ] completed a 6 weeks HIT program. Anthropometric and fitness variables were obtained at pre- and post- HIT. PV variations during warm-up and after supramaximal cycling test (SCT) were calculated using two methods based on Hematocrit (Ht) and Hemoglobin (Hb) measures. After both the warm-up and SCT, PV decreased significantly among participants at pre- and at post-HIT (P < 0.01). However, PV decreases were significantly greater at pre-HIT compared with post-HIT during warm-up and after SCT (P < 0.01, respectively). In addition, at pre-HIT, a positive relationship was found between age and both PV variations at warm-up and after SCT (r2 = 0.55 and r2 = 0.46; P < 0.01 respectively). However, no relationship was found during the post-HIT period. After SCT and after both visits, only body weight predicted 22% of PV variations. In the current study, a significant relationship was found between systolic and diastolic BP improvements and PV variations in post-HIT (r2 = 0.54 and r2 =0.56, P < 0.05, respectively). Our results suggest that HIT may improve PV values and reduce the effects of age on the decrease in PV. These interventions led to improvements in systolic and diastolic BP values among participants.

PMID- 29464885 TI - Effect of Roux-en-Y gastric bypass on liver mitochondrial dynamics in a rat model of obesity. AB - Bariatric surgery provides significant and durable improvements in glycemic control and hepatic steatosis, but the underlying mechanisms that drive improvements in these metabolic parameters remain to be fully elucidated. Recently, alterations in mitochondrial morphology have shown a direct link to nutrient adaptations in obesity. Here, we evaluate the effects of Roux-en-Y gastric bypass (RYGB) surgery on markers of liver mitochondrial dynamics in a diet-induced obesity Sprague-Dawley (SD) rat model. Livers were harvested from adult male SD rats 90-days after either Sham or RYGB surgery and continuous high fat feeding. We assessed expression of mitochondrial proteins involved in fusion, fission, mitochondrial autophagy (mitophagy) and biogenesis, as well as differences in citrate synthase activity and markers of oxidative stress. Gene expression for mitochondrial fusion genes, mitofusin 1 (Mfn1; P < 0.05), mitofusin 2 (Mfn2; P < 0.01), and optic atrophy 1 (OPA1; P < 0.05) increased following RYGB surgery. Biogenesis regulators, peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC1alpha; P < 0.01) and nuclear respiratory factor 1 (Nrf1; P < 0.05), also increased in the RYGB group, as well as mitophagy marker, BCL-2 interacting protein 3 (Bnip3; P < 0.01). Protein expression for Mfn1 (P < 0.001), PGC1alpha (P < 0.05), BNIP3 (P < 0.0001), and mitochondrial complexes I-V (P < 0.01) was also increased by RYGB, and Mfn1 expression negatively correlated with body weight, insulin resistance, and fasting plasma insulin. In the RYGB group, citrate synthase activity was increased (P < 0.02) and reactive oxygen species (ROS) was decreased compared to the Sham control group (P < 0.05), although total antioxidant capacity was unchanged between groups. These data are the first to show an association between RYGB surgery and improved markers of liver mitochondrial dynamics. These observed improvements may be related to weight loss and reduced energetic demand on the liver, which could facilitate normalization of glucose homeostasis and protect against hepatic steatosis. PMID- 29464887 TI - Factitious hypoglycemia in children and adolescents with diabetes. AB - BACKGROUND: Factitious hypoglycemia is a condition of self-induced hypoglycemia due to surreptitious administration of insulin or oral hypoglycemic agents. In adults, it is an uncommon, but well known clinical entity observed in individuals with and without diabetes. OBJECTIVES: To report a case of factitious hypoglycemia highlighting diagnostic pitfalls, to identify common characteristics of children and adolescents with factitious hypoglycemia, and to examine whether the information on long-term outcome exists. METHODS: We present a case of an adolescent with type 1 diabetes who had self-induced hypoglycemia of several years' duration; and we conducted a systematic literature review on factitious hypoglycemia in pediatric patients with diabetes. RESULTS: We identified a total of 83 articles of which 14 met the inclusion criteria (describing 39 cases). All but 1 individual had type 1 diabetes and the majority was female (63%). Average age was 13.5 +/- 2.0 years with the youngest patient presenting at the age 9.5 years. Blood glucose control was poor (hemoglobin A1c: 12.1 +/- 4.0%). In 35%, psychiatric disorders were mentioned as contributing factors. Only 3 reports provided follow-up beyond 6 months. CONCLUSIONS: Factitious hypoglycemia typically occurs in adolescents with type 1 diabetes who use insulin to induce hypoglycemia. Awareness of this differential diagnosis and knowledge of potentially misleading laboratory results may facilitate earlier recognition and intervention. Little information exists on effective treatments and long-term outcome. PMID- 29464888 TI - Postoperative cytological findings from the use of the Integran microfibrillar collagen hemostatic matrix in conization. AB - The Integran microfibrillar collagen hemostatic matrix is one form of microfibrillar collagen hemostat. This form has a sheet-type structure and has explicitly been used in Japan. In gynecology, this sheet-type matrix has helped effect uterine surface hemostasis, especially in myomectomy and cervical conization. However, cytotechnologists and pathologists have overlooked the foreign materials used for conization in postoperative cervical cytology. We report two cases describing the characteristic cervical cytology findings when Integran was used in conization. The first case was a 67-year-old woman who underwent conization because of cervical intraepithelial neoplasia (CIN) 3. Thirty-six days after the surgery, many cylindrical fragments of glossy acellular materials appeared in the cervical cytology. Fortunately, the content did not impede the diagnosis of NILM. The patient then underwent hysterectomy two months after conization. Surgical specimen revealed a high degree of inflammation and granulation without malignancy. Following surgery, the cylindrical fragments disappeared from microscopic findings. The second case was a 45-year-old woman who underwent conization because of CIN3. Thirty-four days after the surgery, many tubular pieces of glossy acellular materials appeared in cervical cytology, as seen in the first case. The cytological diagnosis was NILM. One hundred days after surgery, cervical cytology revealed many clue cells but no cylindrical fragments. These clusters of cylindrical fragments of glossy acellular materials in cervical cytology after conization might induce a delay in diagnosing the persistence and recurrence of cervical cancer. This article is the first report describing cervical cytology findings associated with Integran use. PMID- 29464889 TI - Immediate mandibular reconstruction via patient-specific titanium mesh tray using electron beam melting/CAD/rapid prototyping techniques: One-year follow-up. AB - BACKGROUND: Immediate mandibular reconstruction was performed using a patient specific titanium mesh tray fabricated by electron beam melting (EBM) /rapid prototyping techniques. METHODS: Patient-specific titanium trays were virtually designed and fabricated using EBM technology/rapid prototyping for patients requiring mandibular resection and immediate reconstruction using an iliac crest bone graft. Dental implants were placed in the grafted sites and the patients received prosthetic rehabilitation with a follow-up of one year. Clinical data, postoperative bone formation and complications were evaluated. RESULTS: A symmetric appearance of facial contours was achieved. The titanium tray incorporated the particulate iliac crest bone graft that provided significant bone formation (mean 18.97 +/- 1.45 mm) and predictable results. Stability of the dental implants was achieved. CONCLUSION: The patient-specific titanium meshes and immediate particulate autogenous bone graft showed satisfactory clinical and surgical results in improving patients' quality of life and decreasing the overall treatment time with adequate functional rehabilitation.

AB - Liver ischemia-reperfusion injury (IRI) represents a risk factor for early graft dysfunction and an obstacle to expanding donor pool in orthotopic liver transplantation (OLT). We have reported on the crucial role of macrophage Notch1 signaling in mouse warm hepatic IRI model. However, its clinical relevance or therapeutic potential remain unknown. Here, we used Serelaxin (SER), to verify Notch1 induction and putative hepatoprotective function in ischemia-reperfusion stressed OLT. C57BL/6 mouse livers subjected to extended (18-hour) cold storage were transplanted to syngeneic recipients. SER treatment at reperfusion ameliorated IRI, improved post-OLT survival, decreased neutrophil/macrophage infiltration, and suppressed proinflammatory cytokine programs, while simultaneously increasing Notch intracellular domain (NICD) and hairy and enhancer of split 1 (Hes1) target genes. In bone marrow-derived macrophage cultures, SER suppressed proinflammatory while enhancing antiinflammatory gene expression concomitantly with increased NICD and Hes1. Hepatic biopsies from 21 adult primary liver transplant patients (2 hours postreperfusion) were divided into low-NICD (n = 11) and high-NICD (n = 10) expression groups (western blots). Consistent with our murine findings, human livers characterized by high NICD were relatively IRI resistant, as shown by serum alanine aminotransferase (ALT) levels at day 1 post-OLT. Our study documents the efficacy of SER-Notch1 signaling in mouse OLT and highlights the protective function of Notch1 in liver transplant patients.

AB - The advent of devices that can track interstitial glucose levels, which are closely related to blood glucose levels, on a near continuous basis, has facilitated better insights into patterns of glycaemia. Continuous glucose monitoring (CGM) therefore allows for more intensive monitoring of blood glucose levels and potentially improved glycaemic control. In the context of the announcement on 1 April 2017 that the Australian Government will fund CGM monitoring for people with type 1 diabetes under the age of 21 years, this paper provides a review of the evidence for CGM and some of the ongoing challenges. There is evidence that real-time CGM in type 1 diabetes improves HbA1c and hypoglycaemia, while in type 2 diabetes, the evidence is less robust. Initial barriers to widespread implementation of CGM included issues with accuracy and user friendliness; however, as the technology has evolved, these issues have largely improved. Ongoing barriers include cost, and weaker evidence for their benefit in certain populations such as those with type 2 diabetes and less glycaemic variability. CGM has the potential to reduce healthcare costs, although real-world studies, including cost-effectiveness analyses, are needed in this area.

AB - The efficiencies of mono gradient elution and dual salt-pH gradient elution for separation of six mAb charge and size variants on a preparative-scale ion exchange chromatographic resin are compared in this study. Results showed that opposite dual salt-pH gradient elution with increasing pH gradient and simultaneously decreasing salt gradient is best suited for the separation of these mAb charge and size variants on Eshmuno(r) CPX. Besides giving high binding capacity, this type of opposite dual salt-pH gradient also provides better resolved mAb variant peaks and lower conductivity in the elution pools compared to single pH or salt gradients. To have a mechanistic understanding of the differences in mAb variants retention behaviors of mono pH gradient, parallel dual salt-pH gradient, and opposite dual salt-pH gradient, a linear gradient elution model was used. After determining the model parameters using the linear gradient elution model, 2D plots were used to show the pH and salt dependencies of the reciprocals of distribution coefficient, equilibrium constant, and effective ionic capacity of the mAb variants in these gradient elution systems. Comparison of the 2D plots indicated that the advantage of opposite dual salt-pH gradient system with increasing pH gradient and simultaneously decreasing salt gradient is the noncontinuous increased acceleration of protein migration. Furthermore, the fitted model parameters can be used for the prediction and optimization of mAb variants separation in dual salt-pH gradient and step elution.

PMID- 29464893 TI - Improvements in fitness are not obligatory for exercise training-induced improvements in CV risk factors. AB - The purpose of this study was to assess whether changes in physical fitness relate to changes in cardiovascular risk factors following standardized, center based and supervised exercise training programs in subjects with increased cardiovascular risk. We pooled data from exercise training studies of subjects with increased cardiovascular risk (n = 166) who underwent 8-52 weeks endurance training. We determined fitness (i.e., peak oxygen uptake) and traditional cardiovascular risk factors (body mass index, blood pressure, total cholesterol, high-density lipoprotein cholesterol), before and after training. We divided subjects into quartiles based on improvement in fitness, and examined whether these groups differed in terms of risk factors. Associations between changes in fitness and in cardiovascular risk factors were further tested using Pearson correlations. Significant heterogeneity was apparent in the improvement of fitness and individual risk factors, with nonresponder rates of 17% for fitness, 44% for body mass index, 33% for mean arterial pressure, 49% for total cholesterol, and 49% for high-density lipoprotein cholesterol. Neither the number, nor the magnitude, of change in cardiovascular risk factors differed significantly between quartiles of fitness change. Changes in fitness were not correlated with changes in cardiovascular risk factors (all P > 0.05). Our data suggest that significant heterogeneity exists in changes in peak oxygen uptake after training, while improvement in fitness did not relate to improvement in cardiovascular risk factors. In subjects with increased cardiovascular risk, improvements in fitness are not obligatory for training-induced improvements in cardiovascular risk factors. PMID- 29464895 TI - Selective extraction of lipase and amylase from enzyme mixture by employing liquid emulsion membrane. AB - This work deals with the extraction of lipase and amylase from enzyme mixture by employing liquid emulsion membranes (LEM). The electrostatic interaction between enzymes and reverse micellar surfactant polar head group plays an important role for selective extraction of two different enzymes having different isoelectric points. The optimized conditions for lipase extraction (pH 7.0) resulted in the purification fold and activity recovery of 5.43 fold and 89.53%, respectively, whereas, in case of amylase (pH 9.0) the purification fold and activity recovery were 6.58 and 94.32%, respectively. The results were compared with the control sample (containing individual enzymes) and mixture of enzymes lipase and amylase and it was shown that for optimum conditions the activity recovery and purification fold was higher for the individual enzymes as compared to their mixture. Downstream processing involving LEM was shown to be a feasible method for selective extraction of enzymes. (c) 2018 American Institute of Chemical Engineers Biotechnol. Prog., 34:721-729, 2018. PMID- 29464896 TI - Corticostriatal network dysfunction in Huntington's disease: Deficits in neural processing, glutamate transport, and ascorbate release. AB - AIMS: This review summarizes evidence for dysfunctional connectivity between cortical and striatal neurons in Huntington's disease (HD), a fatal neurodegenerative condition caused by a single gene mutation. The focus is on data derived from recording of electrophysiological signals in behaving transgenic mouse models. DISCUSSIONS: Firing patterns of individual neurons and the frequency oscillations of local field potentials indicate a disruption in corticostriatal processing driven, in large part, by interactions between cells that contain the mutant gene rather than the mutant gene alone. Dysregulation of glutamate, an excitatory amino acid released by cortical afferents, plays a key role in the breakdown of corticostriatal communication, a process modulated by ascorbate, an antioxidant vitamin found in high concentration in striatum. Up regulation of glutamate transport by drug administration or viral-vector delivery improves ascorbate homeostasis and neurobehavioral processing in HD mice. Further analysis of electrophysiological data, including the use of sophisticated computational strategies, is required to discern how behavioral demands modulate the flow of corticostriatal information and its disruption by HD. CONCLUSIONS: Long before massive cell loss occurs, HD impairs the mechanisms by which cortical and striatal neurons communicate. A key problem identified in transgenic animal models is dysregulation of the dynamic changes in extracellular glutamate and ascorbate. Improved understanding of how these neurochemical systems impact corticostriatal communication is necessary before an effective therapeutic strategy can emerge.

PMID- 29464898 TI - Matching donor and recipient based on predicted indirectly recognizable human leucocyte antigen epitopes. AB - The predicted indirectly recognizable human leucocyte antigen (HLA) epitopes (PIRCHE) algorithm is a novel in silico algorithm to determine donor-recipient compatibility. The PIRCHE algorithm determines donor-recipient compatibility by counting the number of mismatched HLA-derived epitopes that are involved in indirect T-cell alloimmune responses; these epitopes are designated as PIRCHE. Over the last few years, the PIRCHE algorithm has been investigated in both hematopoietic stem cell transplantation and solid organ transplantation. This review describes the theory of the algorithm, its application in transplantation, and highlights the future perspectives on the clinical application of the PIRCHE algorithm. PMID- 29464899 TI - Proteomic Adaptation of Australian Epidemic Bordetella pertussis. AB - Bordetella pertussis causes whooping cough. The predominant strains in Australia changed to single nucleotide polymorphism (SNP) cluster I (pertussis toxin promoter allele ptxP3/pertactin gene allele prn2) from cluster II (non-ptxP3/non prn2). Cluster I was mostly responsible for the 2008-2012 Australian epidemic and was found to have higher fitness compared to cluster II using an in vivo mouse competition assay, regardless of host's immunization status. This study aimed to identify proteomic differences that explain higher fitness in cluster I using isobaric tags for relative and absolute quantification (iTRAQ), and high resolution multiple reaction monitoring (MRM-hr). A few key differences in the whole cell and secretome were identified between the cluster I and II strains tested. In the whole cell, nine proteins were upregulated (>1.2 fold change, q < 0.05) and three were downregulated (<0.8 fold change, q < 0.05) in cluster I. One downregulated protein was BP1569, a TLR2 agonist for Th1 immunity. In the secretome, 12 proteins were upregulated and 1 was downregulated which was Bsp22, a type III secretion system (T3SS) protein. Furthermore, there was a trend of downregulation in three T3SS effectors and other virulence factors. Three proteins were upregulated in both whole cell and supernatant: BP0200, molybdate ABC transporter (ModB), and tracheal colonization factor A (TcfA). Important expression differences in lipoprotein, T3SS, and transport proteins between the cluster I and II strains were identified. These differences may affect immune evasion, virulence and metabolism, and play a role in increased fitness of cluster I.

AB - INTRODUCTION: Malaria is a life-threatening infectious disease, which has been for long confined to specific endemic areas. Nevertheless, the recent increase in immigration flows from endemic regions and imported cases has reemphasized many diagnostic challenges in Western countries, thus paving the way to introduce rapid and accurate strategies for screening subjects with suspected Malaria infection. Therefore, the aim of this article was to describe our recent experience with Sysmex XN-module for rapid screening of subjects with suspected Malaria. METHODS: Fourteen patients admitted to the Emergency Department (Papa Giovanni XXIII Hospital Bergamo, Italy) with a clinical suspicion of Malaria infection were evaluated, along with 1047 control samples. The analysis of peripheral blood was performed with XN-module, and results were then compared to optical microscopy. RESULTS: Nine patients were positive to Plasmodim falciparum, 3 to Plasmodim vivax, one to Plasmodim ovale, and one to Plasmodim malarie. Characteristic abnormalities could be observed in both white blood cell differential (WDF) and white cell nucleated (WNR) scattergrams (sensitivity 0.64 and specificity 1.0) in 9 samples with parasites at gametocyte or schizos stage irrespective of Plasmodium species and parasitic index, while characteristic scattergram abnormalities could not be seen in the 5 samples containing only parasites at the trophozoites stage. In these cases, specific variations of some cell population data (CPD) could be recorded (sensitivity 1.00 and specificity 0.91). CONCLUSION: The peculiar abnormalities observed in CPDs, WDF, and WNR scattergrams may raise a definite suspicion of Malaria infection. Further studies should then be planned for validating these preliminary findings and assessing whether these specific abnormalities may be incorporated in rapid and inexpensive Malaria diagnostic algorithms.

PMID- 29464902 TI - Mechanomyographic responses for the biceps brachii are associated with failure times during isometric force tasks. AB - In order to characterize the physiological adjustments within the neuromuscular system that contribute to task failure, this study examined the surface mechanomyographic (MMG) response during maximal and submaximal isometric force tasks of the elbow flexors sustained to failure. The time and frequency components of the MMG signal have shown to be influenced by motor unit activation patterns as well as tetanus. Therefore, it was hypothesized that the rate of change for the MMG response would associate with failure times and would be reduced to a similar degree between the two tasks. The isometric force tasks were performed by the dominant elbow flexors of twenty healthy males (age: 25 +/- 4 years) and MMG was collected from the biceps brachii. Regression analyses were used to model the relationships between the rates of change for MMG versus failure times. There were high levels of interindividual variability in the response patterns, yet the models demonstrated significant negative associations between the rate of change for the MMG responses and failure times during both tasks (R2 = 0.41-0.72, P < 0.05). Similarly, the mean MMG amplitude and frequency values were reduced to comparable levels at the failure point of the two tasks. The results of this study demonstrated that force failure is associated with the rate of diminution in the properties of the muscle force twitch. PMID- 29464904 TI - Genetics of Obesity in Consanguineous Populations: Toward Precision Medicine and the Discovery of Novel Obesity Genes. AB - OBJECTIVE: Consanguinity has been instrumental in the elucidation of many Mendelian genetic diseases. Here, the unique advantage of consanguineous populations was considered in the quest for genes causing obesity. METHODS: PubMed was searched for articles relevant to consanguinity and obesity published between 1995 and 2016. Some earlier articles of interest were also consulted. RESULTS: Although obesity is the most heritable disorder, even in outbred populations, only 2% to 5% of severe obesity cases have so far been proven to be caused by single gene mutations. In some highly consanguineous populations, a remarkably higher proportion of obesity cases because of known and novel monogenic variants has been identified (up to 30%). CONCLUSIONS: Combining the power conferred by consanguinity with current large-capacity sequencing techniques should bring new genetic factors and molecular mechanisms to the fore, unveiling a large part of the yet-elusive neurohumoral circuitry involved in the regulation of energy homeostasis and appetite. Importantly, the undertaking of such initiatives is destined to unfold novel targets for the development of precision medicine relevant to different forms of obesity.

PMID- 29464905 TI - Greater Neonatal Fat-Free Mass and Similar Fat Mass Following a Randomized Trial to Control Excess Gestational Weight Gain. AB - OBJECTIVE: The objective of this study was to determine the effectiveness of controlling maternal gestational weight gain (GWG) in the second and third trimesters on neonate body composition. METHODS: Two hundred ten healthy women with overweight (25 > BMI < 30) or obesity (BMI >= 30) were randomly assigned to a lifestyle intervention (LI) program focused on controlling GWG through nutrition and activity behaviors or to usual obstetrical care (UC). Infant fat and fat-free mass (FFM) at birth were measured by using air displacement plethysmography (PEA POD) and by using quantitative magnetic resonance (QMR). RESULTS: At baseline, there were no between-group differences in maternal characteristics (mean [SD]): age: 33.8 (4.3) years, weight: 81.9 (13.7) kg, BMI: 30.4 (4.5), and gestational age at randomization: 14.9 (0.8) weeks. GWG was less in the LI group by 1.79 kg (P = 0.003) or 0.0501 kg/wk (P = 0.002). Compared with UC infants, LI infants had greater weight (131 +/- 59 g P = 0.03), FFM (98 +/- 45 g; P = 0.03) measured by PEA POD, and lean mass (105 +/- 38 g; P = 0.006) measured by QMR. Fat mass and percent fat were not significantly different. CONCLUSIONS: Intervening in women with overweight and obesity through behaviors promoting healthy diet and physical activity to control GWG resulted in neonates with similar fat and greater FFM.

AB - OBJECTIVE: This study aimed to evaluate the efficacy of a home-based lifestyle intervention delivered through Parents as Teachers (PAT) to reduce excessive gestational weight gain (GWG). METHODS: This was a single-blinded randomized controlled trial conducted as part of the LIFE-Moms consortium at a single university-based tertiary care institution from October 2012 to March 2016. There were 267 socioeconomically disadvantaged (SED) African American women with overweight or obesity (BMI 25.0-45.0 kg/m2 before pregnancy. Participants were randomized to therapy with standard PAT alone (n = 134) or PAT plus a lifestyle intervention program embedded within the standard PAT program (PAT+) (n = 133). Both interventions were delivered in 10 biweekly home visits during pregnancy. The primary outcome was the percentage of women whose GWG exceeded the Institute of Medicine guidelines, and secondary outcomes included both weekly and total GWG. RESULTS: Compared with the standard PAT group in the intent-to-treat analysis, the PAT + group gained less weekly (0.4 kg vs. 0.5 kg/wk; P = 0.04) and total (8.0 kg vs. 9.6 kg; P = 0.02) weight during gestation. Fewer participants in the PAT + group had excessive total GWG (36.1% vs. 45.9%), but the difference between groups was not statistically significant (P = 0.11). CONCLUSIONS: PAT + reduced the weekly and total GWG in SED African American women with overweight or obesity at the start of pregnancy.

PMID- 29464908 TI - Beauty and the Body of the Beholder: Raters' BMI Has Only Limited Association with Ratings of Attractiveness of the Opposite Sex. AB - OBJECTIVE: Assortative mating for adiposity increases the genetic burden on offspring, but its causes remain unclear. One hypothesis is that people who have high adiposity find other people with obesity more physically attractive than lean people. METHODS: The attractiveness of sets of images of males and females who varied in adiposity were rated by opposite sex subjects (559 males and 340 females) across 12 countries. RESULTS: There was tremendous individual variability in attractiveness ratings. For female attractiveness, most males favored the leanest subjects, but others favored intermediate fatness, some were indifferent to body composition, and others rated the subjects with obesity as most attractive. For male images rated by females, the patterns were more complex. Most females favored subjects with low levels of adiposity (but not the lowest level), whereas others were indifferent to body fatness or rated the images depicting individuals with obesity as the most attractive. These patterns were unrelated to rater BMI. Among Caucasian males who rated the images of the thinnest females as being more attractive, the magnitude of the effect depended on rater BMI, indicating limited "mutual attraction." CONCLUSIONS: Individual variations in ratings of physical attractiveness were broadly unrelated to rater BMI and suggest that mutual attraction is an unlikely explanation for assortative mating for obesity. PMID- 29464910 TI - Weighing in on Bariatric Surgery: Effectiveness Among Medicaid Beneficiaries Limited Evidence and Future Research Needs. AB - INTRODUCTION: In the general population, bariatric surgery is well documented as the most effective obesity treatment for sustained weight loss and remission of comorbidities. Characterization of the patient populations most likely to benefit from surgical intervention is needed, but the heterogeneity of treatment effects across payer groups has not been reviewed. METHODS: A systematic review of published studies focusing on bariatric surgery outcomes among Medicaid beneficiaries was conducted. By using PubMed and Scopus, this study searched for studies that quantitatively compared clinical or social bariatric surgery outcomes for United States adult Medicaid recipients and commercially insured patients. RESULTS: Of the 568 titles reviewed, 21 met inclusion criteria. Weight loss and the remission of comorbidities at 1 or 2 years postoperatively were similar between groups despite differences in baseline health status. Short-term health care utilization and mortality outcomes were worse in Medicaid recipients; for instance, Medicaid patients had an average length of stay that was 2 days longer and experienced three more deaths in the first postoperative year. CONCLUSIONS: The critical research gaps in the evidence base needed to improve treatment guidelines for Medicaid patients undergoing bariatric surgery include an understanding of the causes of the baseline health differences and how these differences contribute to postoperative outcomes. PMID- 29464912 TI - BMX-001, a novel redox-active metalloporphyrin, improves islet function and engraftment in a murine transplant model. AB - Islet transplantation has become a well-established therapy for select patients with type 1 diabetes. Viability and engraftment can be compromised by the generation of oxidative stress encountered during isolation and culture. We evaluated whether the administration of BMX-001 (MnTnBuOE-2-PyP5+ [Mn(III) meso tetrakis-(N-b-butoxyethylpyridinium-2-yl)porphyrin]) and its earlier derivative, BMX-010 (MnTE-2-PyP [Mn(III) meso-tetrakis-(N-methylpyridinium-2-yl)porphyrin]) could improve islet function and engraftment outcomes. Long-term culture of human islets with BMX-001, but not BMX-010, exhibited preserved in vitro viability. Murine islets isolated and cultured for 24 hours with 34 MUmol/L BMX-001 exhibited improved insulin secretion (n = 3 isolations, P < .05) in response to glucose relative to control islets. In addition, 34 MUmol/L BMX-001-supplemented murine islets exhibited significantly reduced apoptosis as indicated by terminal deoxynucleotidyl transferase dUTP nick end labeling, compared with nontreated control islets (P < .05). Murine syngeneic islets transplanted under the kidney capsule at a marginal dose of 150 islets revealed 58% of 34 MUmol/L BMX-001 treated islet recipients became euglycemic (n = 11 of 19) compared with 19% of nontreated control islet recipients (n = 3 of 19, P < .05). Of murine recipients receiving a marginal dose of human islets cultured with 34 MUmol/L BMX-001, 92% (n = 12 of 13) achieved euglycemia compared with 57% of control recipients (n = 8 of 14, P = .11). These results demonstrate that the administration of BMX-001 enhances in vitro viability and augments murine marginal islet mass engraftment. PMID- 29464911 TI - CD Obesity-Prone Rats, but not Obesity-Resistant Rats, Robustly Ferment Resistant Starch Without Increased Weight or Fat Accretion. AB - OBJECTIVE: This study used CD obesity-prone (OP) and obesity-resistant (OR) rats to examine how weight gain and fat accretion relate to fermentation levels and microbiota composition after feeding resistant starch (RS). METHODS: After feeding OP rats and OR rats a high-fat (HF) diet for 4 weeks, rats were stratified into three groups: they were fed either an HF diet (group 1: HF-HF) or were switched to a low-fat (LF) diet (group 2: HF-LF) or an LF diet supplemented with 20% RS by weight for 4 weeks (group 3: HF-LFRS). Energy intake, body weight, fermentation variables, and microbiota composition were determined. RESULTS: In OP rats, RS elicited robust fermentation (increased cecal contents, short-chain fatty acids, and serum glucagon-like peptide 1). Total bacteria, species of the Bacteroidales family S24-7, and the archaean Methanobrevibacter smithii increased. The robust fermentation did not elicit higher weight or fat accretion when compared with that of control rats fed the same isocaloric diets (HF-LF +/- RS). In OR rats, body weight and fat accretion were also not different between HF LF +/- RS diets, but RS elicited minimal changes in fermentation and microbiota composition. CONCLUSIONS: Robust fermentation did not contribute to greater weight. Fermentation levels and changes in microbiota composition in response to dietary RS differed by obesity phenotype. PMID- 29464913 TI - Evaluation of nuclear chromatin using grayscale intensity and thresholded percentage area in liquid-based cervical cytology. AB - OBJECTIVES: Development of computerized image analysis techniques has opened up the possibility for the quantitative analysis of nuclear chromatin in pathology. We hypothesized that the features extracted from digital images could be used to determine specific cytomorphological findings for nuclear chromatin that may be applicable for establishing a medical diagnosis. METHODS: Three parameters were evaluated from nuclear chromatin images obtained from the liquid-based cervical cytology samples of patients with biopsy-proven high-grade squamous intraepithelial lesion (HGSIL), and compared between non-neoplastic squamous epithelia and dysplastic epithelia groups: (1) standard deviation (SD) of the grayscale intensity; (2) difference between the maximum and minimum grayscale intensity (M-M); and (3) thresholded area percentage. Each parameter was evaluated at the mean, mean-1SD, and mean-2SD thresholding intensity levels. RESULTS: Between the mean and mean-1SD levels, the thresholded nuclear chromatin pattern was most similar to the chromatin granularity of the unthresholded grayscale images. The SD of the gray intensity and the thresholded area percentage differed significantly between the non-neoplastic squamous epithelia and dysplastic epithelia of HGSIL images at all three thresholding intensity levels (mean, mean-1SD, and mean-2SD). However, the M-M significantly differed between the two sample types for only two of the thresholding intensity levels (mean-1SD and mean-2SD). CONCLUSIONS: The digital parameters SD and M-M of the grayscale intensity, along with the thresholded area percentage could be useful in automated cytological evaluations. Further studies are needed to identify more valuable parameters for clinical application.

PMID- 29464914 TI - Clinical impact of ulceration width, lymphovascular invasion, microscopic satellitosis, perineural invasion, and mitotic rate in patients undergoing sentinel lymph node biopsy for cutaneous melanoma: a retrospective observational study at a comprehensive cancer center. AB - The prognostic significance of the width of the ulceration in primary melanomas remains unclear, and there is a relative paucity of data for lymphovascular invasion (LVI), microscopic satellitosis (MS), perineural invasion (PNI), and mitotic rate when compared with other pathological elements currently required for reporting. To evaluate the prognostic importance of the ulceration width and other important pathologic measurements, a single-institutional retrospective study was conducted using records of cutaneous melanoma patients who underwent sentinel lymph node (SLN) biopsy at The University of Texas, MD Anderson Cancer Center between 2003 and 2008. We identified 1898 eligible patients with median tumor thickness of 1.25 mm and median follow-up of 6.7 years. By multivariable analyses, the strongest risk factor for SLN positivity was high tumor thickness followed by the presence of LVI. The pathologic measures with the strongest influence on recurrence-free survival (RFS) were tumor thickness and positive SLN status. Ulceration width and presence of MS were also significantly associated with RFS while PNI was not. Factors with the strongest influence on melanoma specific survival (MSS) were positive SLN status and mitotic rate. In conclusion, SLN biopsy should probably be offered if the primary tumor has LVI. MS is an adverse prognostic factor for RFS, but its influence on outcome is modest. Ulceration width predicts RFS but loses its independent prognostic significance for MSS when adjusting for currently used clinicopathological factors. In view of its impact on MSS, mitotic rate should be recorded for cutaneous invasive melanomas across all T categories.

AB - The aims of the study were to determine the prevalence of skin tears in the extremities and to explore factors associated with development of skin tears in inpatients at a Danish hospital. The study was designed as a point prevalence survey and included 202 patients in the age range 19-99 (mean: 70.7, SD: 16.5). The patients were assessed for presence of skin tears, numbers, locations and previous skin tears. Data were collected using a data collection sheet developed for a previous study. The survey team consisted of four specialist nurses. Data were collected over a period of 24 hours spread over 3 days. Of the 202 patients, 23 had skin tears, yielding a prevalence of 11.4%. In total, 40 skin tears were observed. Multiple logistic regression analysis showed that previous skin tears (odds ratio (OR): 9.3, 95% confidence interval (CI): 2.6-33.4, P < 0.001), ecchymosis (OR: 5.6, CI: 1.4-23.2, P < 0.017) and risk of falling (OR: 3.8, CI: 1.2-12.0, P < 0.021) were significantly associated with development of skin tears. The prevalence of skin tears in this study (11.4%) matches other international observations. The following risk factors were recognised: previous skin tear, ecchymosis and risk of falling. These factors could be used to identify patients requiring prevention of skin tears.

AB - AIM: The bisoprolol transdermal patch is a newly developed beta-blocker designed to deliver its pharmaceutical ingredient through the skin surface. We aimed to compare the bisoprolol transdermal patch and bisoprolol fumarate tablet using the heart rate variability (HRV). METHOD: Eligible hypertensive patients received a 2 week administration with a 2.5 mg bisoprolol fumarate tablet, followed by 24-hour Holter monitoring. The tablet was then switched to a 4 mg bisoprolol transdermal patch, and after 2 weeks of its administration, the Holter monitoring was repeated. Both drugs were given once daily. Endpoint was any alteration in the HRV caused by a change in the administration route for bisoprolol. RESULTS: There was no difference in the 24-hour time-domain and frequency-domain HRV measurements before and after the drug switching among patients recruited (N = 30). However, the switching significantly altered the time-course curves of the hourly HRV measurements, including the mean normal-to-normal (NN) interval (P = .004), standard deviation of the NN index (P < .001), high frequency component (P = .01), and low frequency component (P = .003). Those alternations were attributed to the slower heart rate and more decreased short-term autonomic fluctuation resulting from the administration of the bisoprolol transdermal patch, which were observed later than 12 hours after the drug initiation. No adverse events were noted throughout the study period. CONCLUSION: The pattern of the autonomic modulation may vary depending on either a transdermal or oral administration even though an equivalent dose of bisoprolol is given.

One assesses socioeconomic status (SES) and the other measures environmental factors. METHODS: The SES questionnaire was composed of 14 questions, which included the presence of several consumer goods, domestic services, family income, parental education level, and current parental occupation status. The environmental questionnaire was composed of 15 questions to measure the social and infrastructure characteristics of the area of residence. Parents or guardians completed the questionnaires on behalf of their children. Adolescents answered the questions themselves for environmental factors, while those related to SES factors were answered by their parents or guardians. We analyzed the reliability of the questionnaires through kappa coefficient determination. Multilevel linear regression models were applied to calculate the correlation between the total household scores, the household income, and parents' education level. RESULTS: The environmental questionnaire showed good reproducibility in both age groups (k = 0.132-0.612 in children and k = 0.392-0.746 in adolescents). The SES questionnaire showed strong reliability in both age groups for all indicators (k = 0.52-1.00 in children and k = 0.296-0.964 in adolescents). CONCLUSIONS: Our multiple indicator questionnaires focused on environmental factors and SES in pediatric health surveys provided useful and easily applicable additional indicators to measure these important determinants of cardiovascular health.

AB - OBJECTIVE: This study aimed to test the validity of an automatic oscillometric device to measure the blood pressure (BP) in children (n = 191) and adolescents (n = 127) aged 3 to 18 years. METHODS: Systolic BP (SBP) and diastolic BP (DBP) levels were measured simultaneous by automatic device and mercury column with Y connection. To verify the validity, Bland-Altman plots and limits of agreement of 95% (95% LOA), specificity and sensitivity of the device, and the grade of British Hypertension Society (BHS) criteria were used. RESULTS: The monitor measurements demonstrated lower measurement bias (mean difference [95% LOA]): 1.4 (-9.9 to 12.8) mmHg in children and 4.3 (-7.8 to 16.5) mmHg in adolescents for SBP. For DBP, it was 2.2 (-7.4 to 11.7) mmHg in children and 1.4 (-8.4 to 11.1) mmHg in adolescents. The sensitivity in children was 21.4 (95% CI = 16.3-26.6), and in adolescents, it was 20.0 (95% CI = 13.2-26.8); the specificity was 95.9 (95% CI = 93.4-98.4) in children and 100.0 (95% CI = 100.0-100.0) in adolescents. The monitor-tested ratings are Grade B for SBP in children and SBP and DBP in adolescents and Grade C for DBP in children. CONCLUSIONS: The automatic monitor presented high values of specificity and lower values of sensitivity to the diagnosis of HBP; however, it can be considered accurate (lower measurement bias) and valid for epidemiological and clinical practice in accordance with BHS criteria. PMID- 29464920 TI - Development of a Food Frequency Questionnaire for Assessing Dietary Intake in Children and Adolescents in South America. AB - OBJECTIVE: This study aimed to describe the development of a food frequency questionnaire (FFQ) to assess dietary intake in South American children and adolescents. METHODS: A total of 345 children (aged 3-10 years) and 357 adolescents (aged 11-17 years) were included for analysis. The FFQ was designed to be self-administered and to assess dietary intake over the past 3 months. It was developed in Spanish and translated into Portuguese. Multiple approaches were considered to compile the food list, and 11 food groups were included. A food photo booklet was produced as supporting material. RESULTS: The FFQ items maintained a common core list among centers (47 items) and country-specific foods. The FFQ for Buenos Aires and Lima had a total of 63 items; there were 55 items for the FFQ in Medelin, 60 items for Montevideo, 58 items for Santiago, 67 items for Sao Paulo, and 68 items for Teresina. Alcohol was also incorporated in the adolescents' FFQ. CONCLUSIONS: We developed a semiquantitative, culturally adapted FFQ to assess dietary intake in children and adolescents in South America. It has an optimal size allowing its completion in a high proportion of the population; therefore, it can be used in epidemiological studies with South American children and adolescents. PMID- 29464921 TI - Design and Objectives of the South American Youth/Child Cardiovascular and Environmental (SAYCARE) Study. AB - OBJECTIVE: The purpose of this paper is to introduce the overarching study design of the South American Youth/Child Cardiovascular and Environmental (SAYCARE) study, which is an observational multicenter feasibility study held in seven South American cities: Buenos Aires (Argentina), Lima (Peru), Medellin (Colombia), Montevideo (Uruguay), Santiago (Chile), and Sao Paulo and Teresina (Brazil). Children and adolescents (3-17 years of age) were studied. METHODS: The data management systems, quality assurance monitoring activities, standardized operating procedure manuals, and training and study management are addressed in this paper. Various quality controls to ensure the collection of valid and reliable data are also discussed. RESULTS AND CONCLUSIONS: Data were obtained from 237 preschoolers and schoolchildren and 258 adolescents during the validation phase measurements. The results of the SAYCARE study are expected to provide higher accuracy in the assessment of cardiovascular disease risk factors, including eating behaviors, body composition, physical activity, sedentary behaviors, lipid profiles and cardiovascular health biomarkers, oral health, social conditions, environmental factors and home environment, and their determinants in children and adolescents from ages 3 to 17 in seven South American cities. PMID- 29464922 TI - Reliability and Validity of a Questionnaire for Physical Activity Assessment in South American Children and Adolescents: The SAYCARE Study. AB - OBJECTIVE: The objective of this article is to test the reliability and validity of the new and innovative physical activity (PA) questionnaire. METHODS: Subsamples from the South American Youth/Child Cardiovascular and Environment Study (SAYCARE) study were included to examine its reliability (children: n = 161; adolescents: n = 177) and validity (children: n = 82; adolescents: n = 60). The questionnaire consists of three dimensions of PA (leisure, active commuting, and school) performed during the last week. To assess its validity, the subjects wore accelerometers for at least 3 days and 8 h/d (at least one weekend day). The reliability was analyzed by correlation coefficients. In addition, Bland-Altman analysis and a multilevel regression were applied to estimate the measurement bias, limits of agreement, and influence of contextual variables. RESULTS: In children, the questionnaire showed consistent reliability (rho = 0.56) and moderate validity (rho = 0.46), and the contextual variable variance explained 43.0% with -22.9 min/d bias. In adolescents, the reliability was higher (rho = 0.76) and the validity was almost excellent (rho = 0.88), with 66.7% of the variance explained by city level with 16.0 min/d PA bias. CONCLUSIONS: The SAYCARE PA questionnaire shows acceptable (in children) to strong (in adolescents) reliability and strong validity in the measurement of PA in the pediatric population from low- to middle-income countries. PMID- 29464923 TI - Effect of acute hypoxemia on cerebral blood flow velocity control during lower body negative pressure. AB - The ability to maintain adequate cerebral blood flow and oxygenation determines tolerance to central hypovolemia. We tested the hypothesis that acute hypoxemia during simulated blood loss in humans would cause impairments in cerebral blood flow control. Ten healthy subjects (32 +/- 6 years, BMI 27 +/- 2 kg.m-2 ) were exposed to stepwise lower body negative pressure (LBNP, 5 min at 0, -15, -30, and -45 mmHg) during both normoxia and hypoxia (Fi O2 = 0.12-0.15 O2 titrated to an SaO2 of ~85%). Physiological responses during both protocols were expressed as absolute changes from baseline, one subject was excluded from analysis due to presyncope during the first stage of LBNP during hypoxia. LBNP induced greater reductions in mean arterial pressure during hypoxia versus normoxia (MAP, at -45 mmHg: -20 +/- 3 vs. -5 +/- 3 mmHg, P < 0.01). Despite differences in MAP, middle cerebral artery velocity responses (MCAv) were similar between protocols (P = 0.41) due to increased cerebrovascular conductance index (CVCi) during hypoxia (main effect, P = 0.04). Low frequency MAP (at -45 mmHg: 17 +/- 5 vs. 0 +/- 5 mmHg2 , P = 0.01) and MCAv (at -45 mmHg: 4 +/- 2 vs. -1 +/- 1 cm.s-2 , P = 0.04) spectral power density, as well as low frequency MAP-mean MCAv transfer function gain (at -30 mmHg: 0.09 +/- 0.06 vs. -0.07 +/- 0.06 cm.s-1 .mmHg-1 , P = 0.04) increased more during hypoxia versus normoxia. Contrary to our hypothesis, these findings support the notion that cerebral blood flow control is not impaired during exposure to acute hypoxia and progressive central hypovolemia despite lower MAP as a result of compensated increases in cerebral conductance and flow variability. PMID- 29464924 TI - Development of a novel affinity chromatography resin for platform purification of bispecific antibodies with modified protein a binding avidity. AB - There is strong interest in the production of bispecific monoclonal antibodies that can simultaneously bind two distinct targets or epitopes to achieve novel mechanisms of action and efficacy. Regeneron's bispecific technology, based upon a standard IgG, consists of a heterodimer of two different heavy chains, and a common light chain. Coexpression of two heavy chains leads to the formation of two parental IgG impurities, the removal of which is facilitated by a dipeptide substitution in the Fc portion of one of the heavy chains that ablates Fc Protein A binding. Therefore, the affinity capture (Protein A) step of the purification process must perform both bulk capture and high resolution of these mAb impurities, a task current commercially available resins are not designed for. Resolution can be further impaired by the ability of Protein A to bind some antibodies in the variable region of the heavy chain (VH ). This article details development of a novel Protein A resin. This resin combines an alkali stable ligand with a base matrix exhibiting excellent mass transfer properties to allow high capacity single step capture and resolution of bispecific antibodies (bsAbs) with high yields. The developed resin, named MabSelect SuReTM pcc, is implemented in GMP production processes for several bsAbs.

PMID- 29464925 TI - Molecular characterization of unusual bovine rotavirus A strains having high genetic relatedness with human rotavirus: evidence for zooanthroponotic transmission. AB - We report here the genomic characterization of two rare rotavirus A (RVAs) G1P[11] and G9P[X] strains detected in cattle calves from two different geographical locations in India during routine rotavirus surveillance. These strains possessed unusual G types (VP7 gene) on a bovine/artiodactyl genotype constellation, G1-P[11]-I2-Rx-Cx-Mx-Ax-N2-T6-E2-H3 (HR-B91) and G9-P[X]-I2-Rx-Cx Mx-Ax-N2-T6-E2-H3 (WB-H2). This is the first report on molecular characterization of G9 in cattle, and second report on G1 in cattle. The VP7 gene of HR-B91 occupied lineage IIc within G1 while that of WB-H2 occupied IIIb within G9 genotype. The latter was found to be very diverse from other RVA strains of G9 genotype, and this may emerge as a new genotype in due course. The study provides evidence of zooanthroponotic transmission of human G1 and G9 RVA genes to calves. Of note, the G9 genotype was found to serve as the ancestral genotype for G1. Phylogenetic analysis of remaining gene segments revealed close relatedness to artiodactyl or artiodactyl-like human RVA strains. The findings of this study highlight the potential role of interspecies transmission and reassortment events in generating the rare rotavirus strains.

AB - This study aims to observe the expression of microRNA (miR)-634 in different gastric cancer cell lines and tissues, and to study the effects of miR-634 on the proliferation, migration, and invasion of the gastric cancer cells. The miR-634 mimics and miR-634 inhibitors were transfected by lentivirus into human gastric cancer SGC-7901 and MGC-803 cells, and the miR-634 cells without transfection were used as the control group (NC group). The expression of miR-634 in the transfected cells was detected by qRT-PCR. Cell viability was measured by the CCK8 assay. The migration and invasion ability of the cells were detected by scratch assays and Transwell(r) chamber assays, respectively, and the luciferase assay verified the binding of miR-634 to the target gene JAG1. The expression level of miR-634 in gastric cancer tissues and cell lines was significantly lower than that in normal adjacent tissues and control cells. The survival of cells was significantly decreased, and number of cells migrating and invading was decreased in the miR-634 mimics group. However, in the miR-634 inhibitor group, the opposite results were observed. Over-expression of miR-634 inhibited the proliferation, migration, and invasion of gastric cancer cell lines, and the miR 634 target gene was JAG1. PMID- 29464927 TI - Microbial lipid extraction from Lipomyces starkeyi using irreversible electroporation. AB - The aim of the study was to investigate the feasibility of using irreversible electroporation (EP) as a microbial cell disruption technique to extract intracellular lipid within short time and in an eco-friendly manner. An EP circuit was designed and fabricated to obtain 4 kV with frequency of 100 Hz of square waves. The yeast cells of Lipomyces starkeyi (L. starkeyi) were treated by EP for 2-10 min where the distance between electrodes was maintained at 2, 4, and 6 cm. Colony forming units (CFU) were counted to observe the cell viability under the high voltage electric field. The forces of the pulsing electric field caused significant damage to the cell wall of L. starkeyi and the disruption of microbial cells was visualized by field emission scanning electron microscopic (FESEM) image. After breaking the cell wall, lipid was extracted and measured to assess the efficiency of EP over other techniques. The extent of cell inactivation was up to 95% when the electrodes were placed at the distance of 2 cm, which provided high treatment intensity (36.7 kWh m-3 ). At this condition, maximum lipid (63 mg g-1 ) was extracted when the biomass was treated for 10 min. During the comparison, EP could extract 31.88% lipid while the amount was 11.89% for ultrasonic and 16.8% for Fenton's reagent. The results recommend that the EP is a promising technique for lowering the time and solvent usage for lipid extraction from microbial biomass.

PMID- 29464928 TI - Metabolic responses and pathway changes of mammalian cells under different culture conditions with media supplementations. AB - Amino acids and glucose consumption, cell growth and monoclonal antibody (mAb) production in mammalian cell culture are key considerations during upstream process and particularly media optimization. Understanding the interrelations and the relevant cellular physiology will provide insight for setting strategy of robust and effective mAb production. The aim of this study was to further our understanding of nutrient consumption metabolism, since this could have significant impact on enhancing mAb titer, cell proliferation, designing feeding strategies, and development of feed media. The nutrient consumption pattern, mAb concentration, and cell growth were analyzed in three sets of cell cultures with media supplementation of glucose, methionine, threonine, tryptophan, and tyrosine. The amino acids metabolism and its impact on cell growth and mAb production during the batch and fed-batch culture were closely analyzed. It was shown that the phenylalanine, tyrosine and tryptophan biosynthesis pathways were significantly altered under different culture conditions with different media. These changes were more apparent in the fed-batch process in which higher mAb titer was observed due to the metabolic changes than mAb titer in the batch process. The pathway analysis approach was well utilized for evaluating the impact on the relevant pathways involved under different cell culture conditions to improve cell growth and mAb titer.

AB - Denervation induces skeletal muscle atrophy, which primarily impairs oxidative slow twitch fibers. The underlying mechanism of this phenomenon, however, remains to be addressed. We hypothesize that denervation-induced fiber-specific atrophy may result from the distinct activities of different signaling pathways that are involved in protein synthesis and degradation in fast- and slow-twitch fibers. In this study, 1-month-old male mice were subjected to unilateral sciatic denervation for 4 days. Fast-twitch muscle extensor digitorum longus (EDL) and slow-twitch muscle soleus were collected from the denervated side and the control side of hind limbs. Total and phosphorylated protein levels of key factors of major signaling pathways in these tissues were determined using western blot assay. Our data showed that total AKT and FoxO3 protein levels were upregulated in denervated muscles as compared with control sides. Phosphorylation of AKT and FoxO3 were proportionally enhanced in denervated EDL but not soleus, indicating AKT activation drives phosphorylation of FoxO3 in EDL but not in soleus upon denervation. As a result, FoxO3-targeted atrogenes MurF1 and Atrogin1 protein abundances were reduced in denervated EDL but not altered in soleus. In consistent with this change, polyubiquitination were significantly increased in denervated soleus, but only a slight increase in ubiquitination was found in denervated EDL. Autophagy marker LC3 protein level was significantly increased in both muscle types, but in greater extent in EDL after denervation. IRS1 protein level and active ERK were reduced in both muscles upon denervation, which might contribute to the upregulation of total AKT protein level and FoxO3 abundance in EDL and soleus. Total and phosphorylated AMPK protein levels were increased in denervated soleus but not in EDL. Overall, these data reveal that the key signaling pathways that regulate protein synthesis and degradation are more sensitive in soleus than EDL in response to denervation.

PMID- 29464936 TI - Evaluation of cellular adhesion and organization in different microporous polymeric scaffolds. AB - The lack of prediction accuracy during drug development and screening risks complications during human trials, such as drug-induced liver injury (DILI), and has led to a demand for robust, human cell-based, in vitro assays for drug discovery. Microporous polymer-based scaffolds offer an alternative to the gold standard flat tissue culture plastic (2D TCPS) and other 3D cell culture platforms as the porous material entraps cells, making it advantageous for automated liquid handlers and high-throughput screening (HTS). In this study, we optimized the surface treatment, pore size, and choice of scaffold material with respect to cellular adhesion, tissue organization, and expression of complex physiologically relevant (CPR) outcomes such as the presence of bile canaliculi like structures. Poly-l-lysine and fibronectin (FN) coatings have been shown to encourage cell attachment to the underlying substrate. Treatment of the scaffold surface with NaOH followed with a coating of FN improved cell attachment and penetration into pores. Of the two pore sizes we investigated (A: 104 +/- 4 MUm; B: 175 +/- 6 MUm), the larger pore size better promoted cell penetration while limiting tissue growth from reaching the hypoxia threshold. Finally, polystyrene (PS) proved to be conducive to cell growth, penetration into the scaffold, and yielded CPR outcomes while being a cost-effective choice for HTS applications. These observations provide a foundation for optimizing microporous polymer-based scaffolds suitable for drug discovery. (c) 2018 American Institute of Chemical Engineers Biotechnol.

AB - AIM: Perivascular adipose tissue (PVAT) is in intimate contact with the vessel wall and extravascular PVAT-derived inflammatory mediators may adversely influence atherosclerotic plaque formation and stability through outside-to inside signaling. We sought to investigate the role of PVAT on the atheroma development in an experimental animal model of metabolic syndrome (MS) associated with oxidative stress and low-grade inflammatory state. We also studied the effect of pioglitazone an insulin sensitizer, on the aortic wall and its surrounding PVAT, considering a bi-directional communication between both layers. METHODS: Apolipoprotein E-deficient mice (ApoE-/- ) were fed with standard diet (CD, control diet) or fructose overload (10% w/v) (FD, fructose diet) for 8 weeks and treated with or without pioglitazone the latest 4 weeks. RESULTS: Biochemical variables show that glycemia and lipid peroxidation determined by thiobarbituric acid reactive species (TBARS) significantly increased in FD-fed ApoE-/- mice. FD significantly increased aortic PVAT expression of oxidative stress associated genes: p22phox , Nox1, Nox2, Nox4 and p47phox , and proinflammatory genes: Visfatin, MCP-1, and MMP-9. Pioglitazone diminished PVAT-oxidative damage elicited by fructose treatment and markedly down-regulated proinflammatory markers. Even pioglitazone did not prevent the development of the aortic atheroma plaques stimulated by FD, significantly diminished VCAM-1 expression, MMP-9 expression and activity in aortic media wall and significantly reduced the accumulation of lipids and macrophages in atheroma plaques. CONCLUSION: Our results support the fact that PVAT contributes to the development and progression of cardiovascular disease by underlying mechanisms elicited by "outside-in" signaling. Treatment with pioglitazone may offer a new effect on the whole vessel wall, promoting the stability of advanced atherosclerotic plaques. PMID- 29464938 TI - Reliability of maximal mitochondrial oxidative phosphorylation in permeabilized fibers from the vastus lateralis employing high-resolution respirometry. AB - The purpose was to assess the impact of various factors on methodological errors associated with measurement of maximal oxidative phosphorylation (OXPHOS) in human skeletal muscle determined by high-resolution respirometry in saponin permeabilized fibers. Biopsies were collected from 25 men to assess differences in OXPHOS between two muscle bundles and to assess the correlation between OXPHOS and the wet weight of the muscle bundle. Biopsies from left and right thighs of another five subjects were collected on two occasions to compare limbs and time points. A single muscle specimen was used to assess effects of the anesthetic carbocaine and the influence of technician. The difference in OXPHOS between two fiber-bundles from the same biopsy exhibited a standard error of measurement (SEM) of 10.5 pmol . s-1 . mg-1 and a coefficient of variation (CV) of 15.2%. The differences between left and right thighs and between two different time points had SEMs of 9.4 and 15.2 pmol . s-1 . mg-1 and CVs of 23.9% and 33.1%, respectively. The average (+/-SD) values obtained by two technicians monitoring different bundles of fibers from the same biopsy were 31.3 +/- 7.1 and 26.3 +/- 8.1 pmol . s-1 . mg-1 . The time that elapsed after collection of the biopsy (up to a least 5 h in preservation medium), wet weight of the bundle (from 0.5 to 4.5 mg) and presence of an anesthetic did not influence OXPHOS. The major source of variation in OXPHOS measurements is the sample preparation. The thigh involved, time-point of collection, size of fiber bundles, and time that elapsed after biopsy had minor or no effect. PMID- 29464939 TI - Genome analysis of two novel Pseudomonas strains exhibiting differential hypersensitivity reactions on tobacco seedlings reveals differences in nonflagellar T3SS organization and predicted effector proteins. AB - Multilocus sequence analysis (MLSA) of two new biological control strains (S1E40 and S3E12) of Pseudomonas was performed to assess their taxonomic position relative to close lineages, and comparative genomics employed to investigate whether these strains differ in key genetic features involved in hypersensitivity responses (HRs). Strain S3E12, at high concentration, incites HRs on tobacco and corn plantlets while S1E40 does not. Phylogenies based on individual genes and 16S rRNA-gyrB-rpoB-rpoD concatenated sequence data show strains S1E40 and S3E12 clustering in distinct groups. Strain S3E12 consistently clustered with Pseudomonas marginalis, a bacterium causing soft rots on plant tissues. MLSA data suggest that strains S1E40 and S3E12 are novel genotypes. This is consistent with the data of genome-based DNA-DNA homology values that are below the proposed cutoff species boundary. Comparative genomics analysis of the two strains revealed major differences in the type III secretion systems (T3SS) as well as the predicted T3SS secreted effector proteins (T3Es). One nonflagellar (NF-T3SS) and two flagellar T3SSs (F-T3SS) clusters were identified in both strains. While F-T3SS clusters in both strains were relatively conserved, the NF-T3SS clusters differed in the number of core components present. The predicted T3Es also differed in the type and number of CDSs with both strains having unique predicted protease-related effectors. In addition, the T1SS organization of the S3E12 genome has protein-coding sequences (CDSs) encoding for key factors such as T1SS secreted agglutinin repeats-toxins (a group of cytolysins and cytotoxins), a membrane fusion protein (LapC), a T1SS ATPase of LssB family (LapB), and T1SS associated transglutaminase-like cysteine proteinase (LapP). In contrast, strain S1E40 has all CDSs for the seven-gene operon (pelA-pelG) required for Pel biosynthesis but not S3E12, suggesting that biofilm formation in these strains is modulated differently. The data presented here provide an insight of the genome organization of these two phytobacterial strains.

PMID- 29464942 TI - Flexible Hydrophobic Antifouling Coating with Oriented Nanotopography and Nonleaking Capsaicin. AB - Incorporating natural product antifoulants (NPAs) into coatings with controlled surface topography is considered a promising way to suppress marine fouling. However, the rapid leakage of NPAs and the relatively complicated process of constructing well-patterned topography remain unresolved problems for practical applications. In this work, capsaicin bonded to CoFe2O4/gelatin magnetic nanoparticles was mixed with a polydimethylsiloxane (PDMS)-based block copolymer. When applied together by a simple spray-coating method, these materials formed a film. The leakage of capsaicin was restrained by the chemical bonds with the CoFe2O4/gelatin nanospheres. The primary nanorough structure was constructed by the phase separation of the PDMS-based copolymer. The secondary nanorough structure was formed by the incorporation of capsaicin-loaded CoFe2O4/gelatin nanospheres, which were demonstrated to improve the orientation of the PDMS-based block copolymer chains. The combination of oriented nanotopography and nonleaking capsaicin endows the coating with enhanced, long-lasting antifouling ability. PMID- 29464943 TI - Molecular Profiling of Pooled Circulating Tumor Cells from Prostate Cancer Patients Using a Dual-Antibody-Functionalized Microfluidic Device. AB - To capture both epithelial and mesenchymal subpopulations of CTCs at different metastatic stages of PCa patients, here we constructed a novel dual-antibody functionalized microfluidic device by employing antibodies against PSMA and EpCAM. In vitro experiments with the dual capture system for capturing both LnCAP and LnCAP-EMT cells have shown significantly enhanced capture efficiency as compared to that of the EpCAM single capture system. Furthermore, the dual capture system could successfully identify CTCs in 20 out of 24 (83.3%) PCa patients, and the CTCs counts from the dual capture system were statistically correlated with the TNM stage of patients ( P < 0.05), while conventional diagnostic methods, such as serum PSA level and Gleason score, failed to correlate to patient TNM stages. To further explore potential clinical application of our dual capture system, captured CTCs were recovered and subjected to qRT-PCR to quantify known factors involved in PCa development and therapy. The results demonstrated that the combined detection of SChLAP1 and PSA in CTCs is a potential marker for identifying patients with metastatic PCa, while detection of AR and PD-L1 in CTCs may have the potential to determine the sensitivity of PCa patients to androgen deprivation therapy and immunotherapy, respectively. Taken together, the dual-antibody-functionalized microfluidic device established in our study overcomes the limitations of some CTC capture platforms that only detect epithelial or mesenchymal CTCs in PCa patients, and detection of the PCa-related RNA signatures from purified CTCs holds great promise to offer warnings for early metastasis of PCa and may provide guidance for therapy decisions. PMID- 29464940 TI - Multiplatform plasma fingerprinting in cancer cachexia: a pilot observational and translational study. AB - BACKGROUND: Cachexia is a metabolic syndrome that affects up to 50-80% of cancer patients. The pathophysiology is characterized by a variable combination of reduced food intake and abnormal metabolism, including systemic inflammation and negative protein and energy balance. Despite its high clinical significance, defined diagnostic criteria and established therapeutic strategies are lacking. The 'omics' technologies provide a global view of biological systems. We hypothesize that blood-based metabolomics might identify findings in cachectic patients that could provide clues to gain knowledge on its pathophysiology, and eventually postulate new therapeutic strategies. METHODS: This is a cross sectional observational study in two cohorts of cancer patients, with and without cachexia. Patients were consecutively recruited from routine clinical practice of a General Oncology Department at '12 de Octubre' University Hospital. Selected clinical and biochemical features were collected. Blood metabolite fingerprinting was performed using three analytical platforms, gas chromatography coupled to mass spectrometry (GC-MS), capillary electrophoresis coupled to mass spectrometry (CE-MS), and liquid chromatography coupled to mass spectrometry (LC-MS). Besides, we performed pathway-based metabolite analyses to obtain more information on biological functions. RESULTS: A total of 15 subjects were included in this study, 8 cachectic and 7 non-cachectic patients. Metabolomic analyses were able to correctly classify their samples in 80% (GC-MS), 97% (CE-MS), 96% [LC-MS (positive mode)], and 89% [LC-MS (negative mode)] of the cases. The most prominent metabolic alteration in plasma of cachectic patients was the decrease of amino acids and derivatives [especially arginine, tryptophan, indolelactic acid, and threonine, with 0.4-fold change (FC) compared with non-cachectic patients], along with the reduction of glycerophospholipids [mainly lysophosphatidylcholines(O-16:0) and lysophosphatidylcholines(20:3) sn-1, FC = 0.1] and sphingolipids [SM(d30:0), FC = 0.5]. The metabolite with the highest increase was cortisol (FC = 1.6). Such alterations suggest a role of the following metabolic pathways in the pathophysiology of cancer cachexia: arginine and proline metabolism; alanine, aspartate, and glutamate metabolism; phenylalanine metabolism; lysine degradation; aminoacyl-tRNA biosynthesis; fatty acid elongation in mitochondria; tricarboxylic acids cycle; among others. CONCLUSIONS: These findings suggest that plasma amino acids and lipids profiling has great potential to find the mechanisms involved in the pathogenesis of cachexia. Metabolic profiling of plasma from cancer patients show differences between cachexia and non-cachexia in amino acids and lipids that might be related to mechanisms involved in its pathophysiology. A better understanding of these mechanisms might identify novel therapeutic approaches to palliate this unmet medical condition. PMID- 29464944 TI - Ultralow Power Consumption Flexible Biomemristors. AB - Low power consumption is the important requirement in memory devices for saving energy. In particular, improved energy efficiency is essential in implantable electronic devices for operation under a limited power supply. Here, we demonstrate the use of kappa-carrageenan (kappa-car) as the resistive switching layer to achieve memory that has low power consumption. A carboxymethyl (CM) group is introduced to the kappa-car to increase its ionic conductivity. Ag was doped in CM:kappa-car to improve the resistive switching properties of the devices. Memory devices based on Ag-doped CM:kappa-car showed electroforming-free resistive switching. This device exhibited low reset voltage (~0.05 V), fast switching speed (50 ns), and high on/off ratio (>103) under low compliance current (10-5 A). Its power consumption (~0.35 MUW) is much lower than those of the previously reported biomemristors. The resistive switching may be a result of an electrochemical redox process and Ag filament formation in the CM:kappa-car under an electric field. This biopolymer memory can also be fabricated on flexible substrate. This study verifies the feasibility of using biopolymers for applications to future implantable and biocompatible nanoelectronics.

AB - Natural A-type procyanidins have shown very interesting biological activities, such as their proven antiadherence properties against pathogenic bacteria. In order to find the structural features responsible for their activities, we describe herein the design and synthesis of six A-type procyanidin analogues and the evaluation of their antimicrobial and antibiofilm properties against 12 resistant bacteria, both Gram positive and Gram negative, isolated from organic foods. The natural A-type procyanidin A-2, which had known antiadherence activity, was also tested as a reference compound for the comparative studies. Within the series, analogue 4, which had a NO2 group on ring A, showed the highest antimicrobial activity (MIC of 10 MUg/mL) and was one of the best molecules at preventing biofilm formation (up to 40% decreases at 100 MUg/mL) and disrupting preformed biofilms (up to 40% reductions at 0.1 MUg/mL). Structure activity relationships are also analyzed. PMID- 29464946 TI - Uptake of TiO2 Nanoparticles into C. elegans Neurons Negatively Affects Axonal Growth and Worm Locomotion Behavior. AB - We employ model organism Caenorhabditis elegans to effectively study the toxicology of anatase and rutile phase titanium dioxide (TiO2) nanoparticles (NPs). The experimental results show that nematode C. elegans can take up fluorescein isothiocyanate-labeled TiO2 NPs and that both anatase and rutile TiO2 NPs can be detected in the cytoplasm of cultured primary neurons imaged by transmission electron microscopy. After TiO2 NP exposure, these neurons also grow shorter axons, which may be related to the detected impeded worm locomotion behavior. Furthermore, anatase TiO2 NPs did not affect the worm's body length; however, we determined that a concentration of 500 MUg/mL of anatase TiO2 NPs reduced the worm population by 50% within 72 h. Notably, rutile TiO2 NPs negatively affect both the body size and worm population. Worms unable to enter the L4 larval stage explain a severe reduction in the worm population at TiO2 NPs LC50/3d. To obtain a better understanding of the cellular mechanisms involved in TiO2 NP intoxication, DNA microarray assays were employed to determine changes in gene expression in the presence or absence of TiO2 NP exposure. Our data reveal that three genes (with significant changes in expression levels) were related to metal binding or metal detoxification (mtl-2, C45B2.2, and nhr-247), six genes were involved in fertility and reproduction (mtl-2, F26F2.3, ZK970.7, clec-70, K08C9.7, and C38C3.7), four genes were involved in worm growth and body morphogenesis (mtl-2, F26F2.3, C38C3.7, and nhr-247), and five genes were involved in neuronal function (C41G6.13, C45B2.2, srr-6, K08C9.7, and C38C3.7).

AB - Surface damage characteristics of single- and multilayer hexagonal boron nitride (h-BN), molybdenum disulfide (MoS2), and graphene films were systematically investigated via atomic force microscopy (AFM)-based progressive-force and constant-force scratch tests and Raman spectroscopy. The film-to-substrate interfacial strengths of these atomically thin films were assessed based on their critical forces (i.e., the normal force where the atomically thin film was delaminated from the underlying substrate), as determined from progressive-force scratch tests. The evolution of surface damage with respect to normal force was further investigated using constant-force tests. The results showed that single layer h-BN, MoS2, and graphene strongly adhere to the SiO2 substrate, which significantly improves its tribological performance. Moreover, defect formation induced by scratch testing was found to affect the topography and friction force differently prior to failure, which points to distinct surface damage characteristics. Interestingly, the residual strains at scratched areas suggest that the scratch test-induced in-plane compressive strains were dominant over tensile strains, thereby leading to buckling in front of the scratching tip and eventually failure at sufficient strains. These trends represent the general failure mechanisms of atomically thin materials because of a scratch test. As the number of layers increased, the tribological performances of atomically thin h BN, MoS2, and graphene were found to significantly improve because of an increase in the interfacial strengths and a decrease in the surface damage and friction force. In all, the findings on the distinctive surface damage characteristics and general failure mechanisms are useful for the design of reliable, protective and solid-lubricant coating layers based on these materials for nanoscale devices.

AB - Several benefits have been described for red wine polyphenols and probiotic strains in the promotion of colonic metabolism and health. On the contrary, knowledge about their role in the management of oral health is still scarce. In this work, the antiadhesive capacity of selected red wine polyphenols and oenological extracts against the oral pathogens Porphyromonas gingivalis, Fusobacterium nucleatum, and Streptococcus mutans in an in vitro model of human gingival fibroblasts has been explored as well as their complementary action with the candidate oral probiotic Streptococcus dentisani. Results highlighted the antiadhesive capacity of caffeic and p-coumaric acids as well as grape seed and red wine oenological extracts. Both, caffeic and p-coumaric acids increased their inhibition potential against S. mutans adhesion when combined with S. dentisani. Additionally, UHPLC-MS/MS analysis demonstrated the oral metabolism of wine phenolics due to both, cellular and bacterial activity. PMID- 29464949 TI - Field Application of 238U/235U Measurements To Detect Reoxidation and Mobilization of U(IV). AB - Biostimulation to induce reduction of soluble U(VI) to relatively immobile U(IV) is an effective strategy for decreasing aqueous U(VI) concentrations in contaminated groundwater systems. If oxidation of U(IV) occurs following the biostimulation phase, U(VI) concentrations increase, challenging the long-term effectiveness of this technique. However, detecting U(IV) oxidation through dissolved U concentrations alone can prove difficult in locations with few groundwater wells to track the addition of U to a mass of groundwater. We propose the 238U/235U ratio of aqueous U as an independent, reliable tracer of U(IV) remobilization via oxidation or mobilization of colloids. Reduction of U(VI) produces 238U-enriched U(IV), whereas remobilization of solid U(IV) should not induce isotopic fractionation. The incorporation of remobilized U(IV) with a high 238U/235U ratio into the aqueous U(VI) pool produces an increase in 238U/235U of aqueous U(VI). During several injections of nitrate to induce U(IV) oxidation, 238U/235U consistently increased, suggesting 238U/235U is broadly applicable for detecting mobilization of U(IV).

AB - We report the design of a novel microcapsule platform for in situ pH sensing and photothermal heating, which involves the encapsulation of pH-responsive polymer coated molybdenum disulfide (MoS2) nanosheets (NSs) in microcapsules with an aqueous core and a semipermeable polymeric shell. The MoS2 NSs were functionalized with pH-responsive polymers having fluorescent groups at the distal end to provide pH-sensitive Forster resonance energy transfer (FRET) effect. The pH-responsive polymers were carefully designed to produce a dramatic change in the polymer conformation, which translated to a change in the FRET efficiency near pH 7.0 in response to subtle pH changes, enabling the detection of cancer cells. The pH-sensitive MoS2 NSs were microfluidically encapsulated within semipermeable membranes to yield microcapsules with a uniform size and composition. The microcapsules retained the MoS2 NSs without leakage while allowing the diffusion of small ions and water through the membrane. At the same time, the membranes excluded adhesive proteins and lipids in the surrounding media, protecting the encapsulated MoS2 NSs from deactivation and enabling in situ pH monitoring. Moreover, the encapsulated MoS2 NSs showed high-performance photothermal heating, rendering the dual-functional microcapsules highly suitable for cancer diagnosis and treatment.

AB - Because of their full compatibility with the modern Si-based technology, the HfO2 based ferroelectric films have recently emerged as viable candidates for application in nonvolatile memory devices. However, despite significant efforts, the mechanism of the polarization switching in this material is still under debate. In this work, we elucidate the microscopic nature of the polarization switching process in functional Hf0.5Zr0.5O2-based ferroelectric capacitors during its operation. In particular, the static domain structure and its switching dynamics following the application of the external electric field have been monitored with the advanced piezoresponse force microscopy (PFM) technique providing a nm resolution. Separate domains with strong built-in electric field have been found. Piezoresponse mapping of pristine Hf0.5Zr0.5O2 films revealed the mixture of polar phase grains and regions with low piezoresponse as well as the continuum of polarization orientations in the grains of polar orthorhombic phase. PFM data combined with the structural analysis of pristine versus trained film by plan-view transmission electron microscopy both speak in support of a monoclinic-to-orthorhombic phase transition in ferroelectric Hf0.5Zr0.5O2 layer during the wake-up process under an electrical stress. PMID- 29464952 TI - High-Content Screening of Plankton Alkaline Phosphatase Activity in Microfluidics. AB - One way for phytoplankton to survive orthophosphate depletion is to utilize dissolved organic phosphorus by expressing alkaline phosphatase. The actual methods to assay alkaline phosphate activity-either in bulk or as a presence/absence of enzyme activity-fail to provide information on individual living cells. In this context, we develop a new microfluidic method to compartmentalize cells in 0.5 nL water-in-oil droplets and measure alkaline phosphatase activity at the single-cell level. We use enzyme-labeled fluorescence (ELF), which is based on the hydrolysis of ELF-P substrate, to monitor in real time and at the single-cell level both qualitative and quantitative information on cell physiology (i.e., localization and number of active enzyme sites and alkaline phosphatase kinetics). We assay the alkaline phosphatase activity of Tetraselmis sp. as a function of the dissolved inorganic phosphorus concentration and show that the time scale of the kinetics spans 1 order of magnitude. The advantages of subnanoliter-scale compartmentalization in droplet-based microfluidics provide a precise characterization of a population with single-cell resolution. Our results highlight the key role of cell physiology to efficiently access dissolved organic phosphorus.

AB - The single-conformation spectroscopy and infrared-induced conformational isomerization of a model protonated pentapeptide [YGPAA + H]+ is studied under cryo-cooled conditions in the gas phase. Building on recent results ( DeBlase , A. F. ; J. Am. Chem. Soc. 2017 , 139 , 5481 - 5493 ), firm assignments are established for the presence of two conformer families with distinct infrared and ultraviolet spectra, using IR-UV depletion spectroscopy. Families (A and B) share a similar structure near the N-terminus but differ in the way that the C-terminal COOH group configures itself (cis versus trans) in forming H-bonds with the peptide backbone. Infrared population transfer (IR-PT) spectroscopy is used to study the IR-induced conformational isomerization following single-conformer infrared excitation. IR-induced isomerization is accomplished in both directions (A -> B and B -> A) in the hydride stretch region and is used to determine fractional abundances for the two conformer families (FA = 0.65 +/- 0.04, FB = 0.35 +/- 0.04, 2sigma error bars). The time scale for collisional cooling of the room-temperature ions to Tvib = 10 K by cold helium in the octupole trap is established as 1.0 ms. Key stationary points on the isomerization potential energy surface are calculated at the DFT B3LYP/6-31+G(d) G3DBJ level of theory. Using RRKM theory, the energy-dependent isomerization rates and populations are calculated as a function of energy. According to the model, the observed population distribution after collisional cooling is close to that of the 298 K Boltzmann distribution and is in near-quantitative agreement with experiment. On the basis of this success, inferences are drawn for the circumstances that govern the population distribution in the trap, concluding that, in ions the size of [YGPAA + H]+ and larger, the observed distributions will be near those at 298 K. PMID- 29464954 TI - Ultrafast, Self-Driven, and Air-Stable Photodetectors Based on Multilayer PtSe2/Perovskite Heterojunctions. AB - We report on the large-scale synthesis of polycrystalline multilayer PtSe2 film with typical semimetallic characteristics. With the availability of the large area film, we constructed a heterojunction composed of multilayer PtSe2 and Cs doped FAPbI3, which can function as a self-driven photodetector in a broadband wavelength from the ultraviolet to the near-infrared region. Further photoresponse analysis revealed that the heterojunction device showed outstanding photosensitive characteristics with a large Ilight/ Idark ratio of 5.7 * 103, high responsivity of 117.7 mA W-1, and decent specific detectivity of 2.91 * 1012 Jones at zero bias. More importantly, the rise/fall times were estimated to be 78/60 ns, rendering our device the fastest device among perovskite-2D photodetectors reported to date. In addition, it was also observed that the PtSe2/perovskite photodetector can almost retain its photoresponse properties after storage in ambient conditions for 3 weeks. This study suggests the potential of the present PtSe2/perovskite heterojunction for future air-stable ultrafast photodetecting applications. PMID- 29464955 TI - The Interplay Between Hydrogen Bonding and Coulombic Forces in Determining the Structure of Sulfuric Acid-Amine Clusters. AB - Acid-base cluster chemistry drives atmospheric new particle formation (NPF), but the details of the growth mechanisms are difficult to experimentally probe. Clusters of ammonia, alkylamines, and sulfuric acid, species fundamental to NPF, are probed by infrared spectroscopy. These spectra show that substitution of amines for ammonia, which is linked to accelerated growth, induces profound structural rearrangement in clusters with initial compositions (NH4+) n+1(HSO4-) n (1 <= n <= 3). This rearrangement is driven by the loss of N-H hydrogen bond donors, yielding direct bisulfate-bisulfate hydrogen bonds, and its onset with respect to cluster composition indicates that more substituted amines induce rearrangement at smaller sizes. A simple model counting hydrogen bond donors and acceptors explains these observations. The presence of direct hydrogen bonds between formal anions shows that hydrogen bonding can compete with Coulombic forces in determining cluster structure. These results suggest that NPF mechanisms may be highly dependent on amine identity. PMID- 29464956 TI - Characterization of Indole-3-acetic Acid Biosynthesis and the Effects of This Phytohormone on the Proteome of the Plant-Associated Microbe Pantoea sp. YR343. AB - Indole-3-acetic acid (IAA) plays a central role in plant growth and development, and many plant-associated microbes produce IAA using tryptophan as the precursor. Using genomic analyses, we predicted that Pantoea sp. YR343, a microbe isolated from Populus deltoides, synthesizes IAA using the indole-3-pyruvate (IPA) pathway. To better understand IAA biosynthesis and the effects of IAA exposure on cell physiology, we characterized proteomes of Pantoea sp. YR343 grown in the presence of tryptophan or IAA. Exposure to IAA resulted in upregulation of proteins predicted to function in carbohydrate and amino acid transport and exopolysaccharide (EPS) biosynthesis. Metabolite profiles of wild-type cells showed the production of IPA, IAA, and tryptophol, consistent with an active IPA pathway. Finally, we constructed an Delta ipdC mutant that showed the elimination of tryptophol, consistent with a loss of IpdC activity, but was still able to produce IAA (20% of wild-type levels). Although we failed to detect intermediates from other known IAA biosynthetic pathways, this result suggests the possibility of an alternate pathway or the production of IAA by a nonenzymatic route in Pantoea sp. YR343. The Delta ipdC mutant was able to efficiently colonize poplar, suggesting that an active IPA pathway is not required for plant association. PMID- 29464958 TI - sp-d Exchange Interactions in Wave Function Engineered Colloidal CdSe/Mn:CdS Hetero-Nanoplatelets. AB - In two-dimensional (2D) colloidal semiconductor nanoplatelets, which are atomically flat nanocrystals, the precise control of thickness and composition on the atomic scale allows for the synthesis of heterostructures with well-defined electron and hole wave function distributions. Introducing transition metal dopants with a monolayer precision enables tailored magnetic exchange interactions between dopants and band states. Here, we use the absorption based technique of magnetic circular dichroism (MCD) to directly prove the exchange coupling of magnetic dopants with the band charge carriers in hetero nanoplatelets with CdSe core and manganese-doped CdS shell (CdSe/Mn:CdS). We show that the strength of both the electron as well as the hole exchange interactions with the dopants can be tuned by varying the nanoplatelets architecture with monolayer accuracy. As MCD is highly sensitive for excitonic resonances, excited level spectroscopy allows us to resolve and identify, in combination with wave function calculations, several excited state transitions including spin-orbit split-off excitonic contributions. Thus, our study not only demonstrates the possibility to expand the extraordinary physical properties of colloidal nanoplatelets toward magneto-optical functionality by transition metal doping but also provides an insight into the excited state electronic structure in this novel two-dimensional material.

AB - An enantioselective and diastereoselective approach toward the synthesis of the tetracyclic scaffold of the furanobutenolide-derived polycyclic norditerpenoids is described. Focusing on synthetic efforts toward ineleganolide, the synthetic approach utilizes a palladium-catalyzed enantioselective allylic alkylation for the construction of the requisite chiral tertiary ether. A diastereoselective cyclopropanation-Cope rearrangement cascade enabled the convergent assembly of the ineleganolide [6,7,5,5]-tetracyclic scaffold. Investigation of substrates for this critical tandem annulation process is discussed along with synthetic manipulations of the [6,7,5,5]-tetracyclic scaffold and the attempted interconversion of the [6,7,5,5]-tetracyclic scaffold of ineleganolide to the isomeric [7,6,5,5]-core of scabrolide A and its naturally occurring isomers. Computational evaluation of ground-state energies of late-stage synthetic intermediates was used to guide synthetic development and aid in the investigation of the conformational rigidity of these highly constrained and compact polycyclic structures. PMID- 29464959 TI - Angstrom-Size Defect Creation and Ionic Transport through Pores in Single-Layer MoS2. AB - Atomic-defect engineering in thin membranes provides opportunities for ionic and molecular filtration and analysis. While molecular-dynamics (MD) calculations have been used to model conductance through atomic vacancies, corresponding experiments are lacking. We create sub-nanometer vacancies in suspended single layer molybdenum disulfide (MoS2) via Ga+ ion irradiation, producing membranes containing ~300 to 1200 pores with average and maximum diameters of ~0.5 and ~1 nm, respectively. Vacancies exhibit missing Mo and S atoms, as shown by aberration-corrected scanning transmission electron microscopy (AC-STEM). The longitudinal acoustic band and defect-related photoluminescence were observed in Raman and photoluminescence spectroscopy, respectively. As the irradiation dose is increased, the median vacancy area remains roughly constant, while the number of vacancies (pores) increases. Ionic current versus voltage is nonlinear and conductance is comparable to that of ~1 nm diameter single MoS2 pores, proving that the smaller pores in the distribution display negligible conductance. Consistently, MD simulations show that pores with diameters <0.6 nm are almost impermeable to ionic flow. Atomic pore structure and geometry, studied by AC STEM, are critical in the sub-nanometer regime in which the pores are not circular and the diameter is not well-defined. This study lays the foundation for future experiments to probe transport in large distributions of angstrom-size pores. PMID- 29464960 TI - Composition-Dependent Energy Splitting between Bright and Dark Excitons in Lead Halide Perovskite Nanocrystals. AB - Perovskite semiconductor nanocrystals with different compositions have shown promise for applications in light-emitting devices. Dark excitonic states may suppress light emission from such nanocrystals by providing an additional nonradiative recombination channel. Here, we study the composition dependence of dark exciton dynamics in nanocrystals of lead halides by time-resolved photoluminescence spectroscopy at cryogenic temperatures. The presence of a spin related dark state is revealed by magneto-optical spectroscopy. The energy splitting between bright and dark states is found to be highly sensitive to both halide elements and organic cations, which is explained by considering the effects of size confinement and charge screening, respectively, on the exchange interaction. These findings suggest the possibility of manipulating dark exciton dynamics in perovskite semiconductor nanocrystals by composition engineering, which will be instrumental in the design of highly efficient light-emitting devices. PMID- 29464961 TI - Spatially Resolved Lateral Transmission Measurements to Characterize Changes in the Scattering Coefficient and the Anisotropy Factor. AB - A new setup is described to characterize the scattering coefficient and the scattering phase function of liquid media. The setup utilizes the basic idea of a spatially resolved reflectance measurement combined with a sophisticated illumination geometry. The sample is illuminated parallel and close to the interface of the sample and a glass window to get information from single scattered and multiple scattered light. By illuminating the sample with a fiber orientated with the axis parallel to the glass surface, small distances to the source can be examined unimpeded by the illumination beam. The derived information is, for example, not only sensitive to the concentration of the scatterers but also to the size of the scattering particles. We present the setup including the theory to describe the light propagation in the whole configuration using Monte Carlo simulations. The validation has been done with polystyrene microsphere dispersions with different scattering coefficients. As application for the developed setup, we show measurements of different milk samples which vary in concentration of fat, protein, and in fat droplet size during homogenization process. By measuring milk, we show the ability of the sensor to determine information about the scattering phase function without diluting the sample. For sensors in the dairy industry, a measurement with no pre-processing and no diluting of the sample is worthwhile, because this can be used to determine the fat and protein concentration on-line.

AB - Background Pyromania is a rare disorder that is characterized by multiple episodes of deliberate and purposeful fire-setting. It is typically associated with significant psychosocial dysfunction and legal problems. Even so, little research has examined cognitive aspects of the disorder. Case presentation/study In this study, we compared a 24-year-old woman with pyromania with 19 age- and gender-matched healthy controls using a battery of computerized neurocognitive tasks. Our participant affected by pyromania showed impaired cognitive flexibility but intact functioning on measures of impulsive action and decision making. Discussion Although pyromania shares phenomenological similarities with other urge-driven disorders, our results suggest that pyromania may have features of compulsivity as well. Conclusions Pyromania is relatively understudied from a neurobiological perspective. Further research is needed to understand the pathophysiology, classification, and treatment of pyromania.

AB - The term comparative effectiveness research (CER) took center stage with passage of the American Recovery and Reinvestment Act (2009). The companion US$1.1 billion in funding prompted the launch of initiatives to train the scientific workforce capable of conducting and using CER. Passage of the Patient Protection and Affordable Care Act (2010) focused these initiatives on patients, coining the term 'patient-centered outcomes research' (PCOR). Educational and training initiatives were soon launched. This report describes the initiative of the Pharmaceutical Research and Manufacturers Association of America (PhRMA) Foundation. Through provision of grant funding to six academic Centers of Excellence, to spearheading and sponsoring three national conferences, the PhRMA Foundation has made significant contributions to creation of the scientific workforce that conducts and uses CER/PCOR.

AB - Evidence from comparative effectiveness research (CER) and patient-centered outcomes research (PCOR) studies are increasingly available in the literature. However, there remain opportunities to better integrate that evidence into decision-making. An invitation-only conference held in January 2017, titled "Comparative Effectiveness and Patient-Centered Outcomes Research: Enhancing Uptake and Use by Patients, Clinicians and Payers", sought to identify and discuss both gaps in the uptake and use of CER/PCOR, and approaches to enhance the uptake and use of CER/PCOR evidence by patients, clinicians and payers. In this article, we summarize the conference proceedings, and highlight the themes and recommendations that resulted from the sessions. This paper also introduces other articles in this issue of CER from that conference. PMID- 29464966 TI - Trends in transfusion rates after the FOCUS trial. AB - AIM: We estimate the impact of the FOCUS trial, which concluded that hip surgery patients with hemoglobin values above 8 g/dl do not benefit from routine transfusions, on transfusion rates. METHODS: We evaluated trends in transfusion rates using inpatient discharge data from four states. RESULTS: The transfusion rate was 5.2 percentage points lower in the fourth quarter of 2013 than it would have been had pre-FOCUS trends continued. Transfusion rates declined more in hospitals with a low end-of-life treatment intensity index, a general measure of treatment intensity. CONCLUSION: The FOCUS trial affected practice, but there are additional opportunities to reduce the use of transfusions.

AB - Clostridioides difficile (C. difficile) has become a pathogen of worldwide importance considering that epidemic strains are disseminated in hospitals of several countries, where community-acquired infections act as a constant source of new C. difficile strains into hospitals. Despite the advances in the treatment of infections, more effective therapies against C. difficile are needed but, at the same time, these therapies should be less harmful to the resident gastrointestinal microbiota.

CONCLUSION: M-PCR showed superiority over Xpert assay and may facilitate an efficient diagnosis of pleural TB. PMID- 29464971 TI - Inflammatory Nodules Identify Steroid-Responsive Primary Sclerosing Cholangitis. AB - Primary sclerosing cholangitis (PSC) is a cholangiopathy-usually associated with inflammatory bowel disease-that leads to cirrhosis and liver failure. Based on a multitude of clinical trials, there is general consensus that PSC progression is unchanged by current therapies, including steroids. However, there are scattered reports in the literature of PSC patients responsive to steroids. Recently, several steroid-responsive PSC mimics have been described, most notably immunoglobulin G4-related sclerosing cholangitis. Following these discoveries, many assume that cases in the literature previously reported as steroid responsive PSC would now be classified as one of these mimics. We reviewed liver biopsies and the medical histories of patients diagnosed with PSC with documented response to steroids. We identified 3 cases of steroid-responsive PSC in patients with inflammatory bowel disease that do not fit criteria of known PSC mimics. All 3 were adults (age range = 18-44 years) with inflammatory bowel disease, and included 2 males and 1 female. All 3 patients had abnormal liver function tests that normalized on prednisone. Histologically, these 3 cases share a common feature, hepatic fibroinflammatory nodules in a collagen-rich background. They lacked clinical, serologic, and histologic features of immunoglobulin G4-related sclerosing cholangitis. These cases suggest that fibroinflammatory nodules may identify a unique subset of PSC patients who are responsive to steroids.

PMID- 29464973 TI - Trajectories of Episodic Disability in People Aging with HIV: A Longitudinal Qualitative Study. AB - People living with HIV may experience disability which is episodic in nature, characterized by periods of wellness and illness. The purpose of this longitudinal qualitative study was to understand how the episodic nature of HIV and the associated uncertainty shape the disability experience of older adults living with HIV over time. Fourteen men and 10 women who were HIV positive and over 50 years (mean age: 57 years; range: 50-73) participated in 4 interviews over 20 months. Longitudinal analyses of the transcribed interviews identified 4 phenotypes of episodic disability over time: decreasing, increasing, stable, or significant fluctuations. Although all participants experienced uncertainty, acceptance and optimism were hallmarks of those whose phenotypes were stable or improved over time. Understanding a person's episodic trajectory may help to tailor interventions to promote stability, mitigate an upward trajectory of increasing disability, and increase the time between episodes of illness. PMID- 29464974 TI - A Comparison of Spastic Diplegia in Term and Preterm-Born Children. AB - This study compared the risk factors and clinical and radiologic profile of children with spastic diplegic cerebral palsy born at term (>=37 weeks) with those born preterm. Children (2-14 years) with cerebral palsy meeting the study criteria for spastic diplegia were enrolled. Antecedent risk factors, clinical profile, and magnetic resonance imaging (MRI) findings were recorded. Spasticity, functional ability, intellectual ability, and social quotient were assessed using standard scales. Ninety-three children met the study inclusion criteria (45 term, 48 preterm). Moderate to severe intellectual disability (53% vs 21%, P = .001) and epilepsy (51% vs 33%) were significantly more common in term-born children, whereas periventricular white matter injury was less common in term-born children (64%vs 89.4%, P = .004). Term spastic diplegia was associated with cortical/subcortical involvement in (11/42 (26%) vs 3/47(6.4%); P = .01). We conclude that term-spastic-diplegia is clinicopathologically different from preterm-spastic-diplegia. Their neuroradiologic pattern also differs with more frequent involvement of cortical/subcortical areas.

AB - Until recently, palliative options for the treatment of platinum-refractory recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC) have been cytotoxic chemotherapy and EGFR inhibitors. These agents offer limited efficacy with substantial toxicity. The development of novel immune checkpoint inhibitors has challenged the standard treatment. Pembrolizumab is a potent and highly selective humanized monoclonal antibody that blocks the interaction between PD-1, an immune checkpoint receptor and its ligands PD-L1 and -2. In August 2016, the US FDA approved the use of pembrolizumab in R/M HNSCC following disease progression on or after platinum-containing chemotherapy. This review highlights the pharmacology, therapeutic efficacy and tolerability data relevant to the use of pembrolizumab for the treatment of R/M HNSCC. Readers will gain greater insight into the HNSCC tumor microenvironment, available biomarkers, and learn about important clinical considerations associated with the use of pembrolizumab and similar immune checkpoint inhibitors.

AB - PURPOSE: Chronic, low-grade inflammation is a proposed etiological factor associated with schizophrenia. Thus, various studies have been conducted to understand the role of inflammatory process in schizophrenia by using inflammatory maker C-reactive protein (CRP) with conflicting findings. Inadvertently, studies of CRP among the Indian schizophrenia patients are very few. Therefore, the present study was undertaken to investigate the role of inflammatory process among Indian Bengalee schizophrenia patients of Siliguri, using the marker CRP and its stimulating cytokine interleukin-6 (IL-6). In addition, the study also intended to investigate the immunomodulatory effect of antipsychotic medication on serum levels of CRP and IL-6. MATERIALS AND METHODS: The serum levels of CRP and IL-6 were measured by Enzyme-Linked Immunosorbent Assay (ELISA) among 67 antipsychotic medicating, 28 psychotropic medication-free schizophrenia patients, and it was compared with 72 age, sex and ethnicity matched controls. RESULTS: A significantly higher level of CRP and IL-6 were recorded among the antipsychotic medicating patients. Although CRP was found to be higher among the psychotropic medication-free patients than the controls, it was not found to be significant. However, a significantly higher level of IL-6 was observed in this group. CONCLUSIONS: The results provide the evidence for a possible immunomodulatory effect of antipsychotic drugs on CRP. Future investigations including the study of antipsychotics separately may help to understand the differential effects of individual antipsychotics on CRP level. Additional studies with a larger sample size of psychotropic medication-free patients may help to verify the role of inflammation in schizophrenia patients of this region.

AB - OBJECTIVE: To investigate whether small-for-gestational-age (SGA) and large-for gestational-age (LGA) birth weight at-term poses an increased risk for long-term pediatric endocrine morbidity. STUDY DESIGN: A retrospective population-based cohort study compared the incidence of long-term pediatric hospitalizations due to endocrine morbidity of singleton children born SGA, appropriate-for gestational-age (AGA), and LGA at-term. A multivariate generalized estimating equation (GEE) logistic regression model analysis was used to control for confounders. RESULTS: During the study period, 235,614 deliveries met the inclusion criteria; of which 4.7% were SGA (n = 11,062), 91% were AGA (n = 214,249), and 4.3% were LGA neonates (n = 10,303). During the follow-up period, children born SGA or LGA at-term had a significantly higher rate of long-term endocrine morbidity. Using a multivariable GEE logistic regression model, controlling for confounders, being delivered SGA or LGA at-term was found to be an independent risk factor for long-term pediatric endocrine morbidity (Adjusted OR = 1.4; 95%CI = 1.1-1.8; p = .015 and aOR = 1.4; 95%CI = 1.1-1.8; p = .005, respectively). Specifically, LGA was found an independent risk factor for overweight and obesity (aOR = 1.7; 95%CI = 1.2-2.5; p = .001), while SGA was found an independent risk factor for childhood hypothyroidism (aOR = 3.2; 95%CI = 1.8-5.8; p = .001). CONCLUSIONS: Birth weight either SGA or LGA at-term is an independent risk factor for long-term pediatric endocrine morbidity. PMID- 29464979 TI - Erratum: Halson and Lastella (2017).

PMID- 29464980 TI - Evaluation the efficacy of trichloroacetic acid (TCA) 33% in treatment of oral retinoid-induced cheilitis compared with placebo (Vaseline): a randomized pilot study. AB - BACKGROUND: Oral Isotretinoin (13-cis-retinoic acid) is a gold standardtreatment for severe forms of acne with cheilitis as a most frequent complication. We designed this novel study to investigate the therapeutic effect of trichloroacetic acid (TCA) 33% as compared with placebo to treat cheilitis. METHODS: In this pilot study, 90 acne vulgaris patients between 18 and 50 years, who referred dermatologic clinic with cheilitis, were assigned to either case (TCA) or control (Vaseline) group using permuted-block randomization from 2013 to 2015 with data analysis in 2016. Patients had follow-up visits after 2 and 6 weeks, at which their lesions were photographed. Two blinded expert dermatologists recorded physician International global score for each image. RESULTS: Ninety eligible patients were randomly allocated into two groups. This included 45 patients in each group. At the end of follow-up, 44 patients in the intervention group and 37 patients in control group completed the final assessment. Compared to the control group, the TCA group had a greater reduction in the mean ICGS value from baseline to Week 6 (mean difference 2.59 points, p < .0001). CONCLUSIONS: TCA can be considered as a good strategy in improvement of cheilitis to isotretinoin therapy. PMID- 29464981 TI - Multiple sclerosis-related fatigue: Altered resting-state functional connectivity of the ventral striatum and dorsolateral prefrontal cortex. AB - OBJECTIVE: Since recent studies suggested a role of the striatum and prefrontal cortex for multiple sclerosis (MS)-related fatigue, we investigated resting-state functional connectivity alterations of striatal subdivisions and the dorsolateral prefrontal cortex (dlPFC). METHODS: Resting-state functional magnetic resonance imaging was acquired in 77 relapsing-remitting MS patients (38 fatigued (F-MS), 39 non-fatigued (NF-MS)) and 41 matched healthy controls (HC). Fatigue severity was assessed using the fatigue severity scale. Seed-based connectivity analyses were performed using subregions of the striatum and the dlPFC as regions of interest applying non-parametric permutation testing. RESULTS: Compared to HC and NF-MS patients, F-MS patients showed reduced caudate nucleus and ventral striatum functional connectivity with the sensorimotor cortex (SMC) and frontal, parietal, and temporal cortex regions. Fatigue severity correlated negatively with functional connectivity of the caudate nucleus and ventral striatum with the SMC and positively with functional connectivity of the dlPFC with the rostral inferior parietal gyrus and SMC. CONCLUSION: MS-related fatigue is associated with reduced functional connectivity between the striatum and sensorimotor as well as attention and reward networks, in which the ventral striatum might be a key integration hub. Together with increased connectivity between the dlPFC and sensory cortical areas, these connectivity alterations shed light on the mechanisms of MS-related fatigue. PMID- 29464982 TI - RCC1 regulates inner centromeric composition in a Ran-independent fashion. AB - RCC1 associates to chromatin dynamically within mitosis and catalyzes Ran-GTP production. Exogenous RCC1 disrupts kinetochore structure in Xenopus egg extracts (XEEs), but the molecular basis of this disruption remains unknown. We have investigated this question, utilizing replicated chromosomes that possess paired sister kinetochores. We find that exogenous RCC1 evicts a specific subset of inner KT proteins including Shugoshin-1 (Sgo1) and the chromosome passenger complex (CPC). We generated RCC1 mutants that separate its enzymatic activity and chromatin binding. Strikingly, Sgo1 and CPC eviction depended only on RCC1's chromatin affinity but not its capacity to produce Ran-GTP. RCC1 similarly released Sgo1 and CPC from synthetic kinetochores assembled on CENP-A nucleosome arrays. Together, our findings indicate RCC1 regulates kinetochores at the metaphase-anaphase transition through Ran-GTP-independent displacement of Sgo1 and CPC. PMID- 29464983 TI - Repurposing anticancer drugs for targeting necroptosis. AB - Necroptosis represents a form of programmed cell death that can be engaged by various upstream signals, for example by ligation of death receptors, by viral sensors or by pattern recognition receptors. It depends on several key signaling proteins, including the kinases Receptor-Interacting Protein (RIP)1 and RIP3 and the pseudokinase mixed-lineage kinase domain-like protein (MLKL). Necroptosis has been implicated in a number of physiological and pathophysiological conditions and is disturbed in many human diseases. Thus, targeted interference with necroptosis signaling may offer new opportunities for the treatment of human diseases. Besides structure-based drug design, in recent years drug repositioning has emerged as a promising alternative to develop drug-like compounds. There is accumulating evidence showing that multi-targeting kinase inhibitors, for example Dabrafenib, Vemurafenib, Sorafenib, Pazopanib and Ponatinib, used for the treatment of cancer also display anti-necroptotic activity. This review summarizes recent evidence indicating that some anticancer kinase inhibitors also negatively affect necroptosis signaling. This implies that some cancer therapeutics may be repurposed for other pathologies, e.g. ischemic or inflammatory diseases. PMID- 29464984 TI - The challenges of implementing advanced access for residents in family medicine in Quebec. Do promising strategies exist? AB - BACKGROUND: The advanced access (AA) model is a highly recommended innovation to improve timely access to primary healthcare. Despite that many studies have shown positive impacts for healthcare professionals, and for patients, implementing this model in clinics with a teaching mission for family medicine residents poses specific challenges. OBJECTIVE: To identify these challenges within these clinics, as well as potential strategies to address them. DESIGN: The authors adopted a qualitative multiple case study design, collected data in 2016 using semi-structured interviews (N = 40) with healthcare professionals and clerical staff in four family medicine units in Quebec, and performed a thematic analysis. They validated results through a discussion workshop, involving many family physicians and residents practicing in different regions Results: Five challenges emerged from the data: 1) choosing, organizing residents' patient; 2) managing and balancing residents' appointment schedules; 3) balancing timely access with relational continuity; 4) understanding the AA model; 5) establishing collaborative practices with other health professionals. Several promising strategies were suggested to address these challenges, including clearly defining residents' patient panels; adopting a team-based care approach; incorporating the model into academic curriculum and clinical training; proactive and ongoing education of health professionals, residents, and patients; involving residents in the change process and in adjustment strategies. CONCLUSIONS: To meet the challenges of implementing AA, decision-makers should consider exposing residents to AA during academic training and clinical internships, involving them in team work on arrival, engaging them as key actors in the implementation and in intra- and inter-professional collaborative models.

AB - Background Investigators use phase-contrast magnetic resonance (PC-MR) and computational fluid dynamics (CFD) to assess cerebrospinal fluid dynamics. We compared qualitative and quantitative results from the two methods. Methods Four volunteers were imaged with a heavily T2-weighted volume gradient echo scan of the brain and cervical spine at 3T and with PC-MR. Velocities were calculated from PC-MR for each phase in the cardiac cycle. Mean pressure gradients in the PC MR acquisition through the cardiac cycle were calculated with the Navier-Stokes equations. Volumetric MR images of the brain and upper spine were segmented and converted to meshes. Models of the subarachnoid space were created from volume images with the Vascular Modeling Toolkit. CFD simulations were performed with a previously verified flow solver. The flow patterns, velocities and pressures were compared in PC-MR and CFD flow images. Results PC-MR images consistently revealed more inhomogeneous flow patterns than CFD, especially in the anterolateral subarachnoid space where spinal nerve roots are located. On average, peak systolic and diastolic velocities in PC-MR exceeded those in CFD by 31% and 41%, respectively. On average, systolic and diastolic pressure gradients calculated from PC-MR exceeded those of CFD by 11% and 39%, respectively. Conclusions PC-MR shows local flow disturbances that are not evident in typical CFD. The velocities and pressure gradients calculated from PC-MR are systematically larger than those calculated from CFD.

AB - OBJECTIVES: Thymoquinone (TQ), the main active ingredient in Nigella sativa oil, exhibits various bioactivities. This study aimed to investigate the effect of TQ on neurobehavioral and neuropathological alterations induced by aluminum trichloride (AlCl3) and D-galactose (D-gal)-in male rats and to explore the related mechanisms. METHODS: D-gal (60 mg/kg day) and AlCl3 (10 mg/kg day) were given intraperitoneally (i.p.) once daily for 42 days and after 4 weeks TQ was concomitantly administered intragastrically (i.g.) (20 mg/kg/day) once daily for 14 days. Then, memory function was evaluated by Morris water maze test (MWM). Superoxide dismutase (SOD), Total antioxidant capacity (TAC), Acetylcholinesterase (AChE) activities, and malondialdehyde (MDA), nitric oxide (NO), brain-derived neurotrophic factor (BDNF), and B-cell lymphoma-2 (Bcl-2) levels in whole brain were assessed with the biochemical technique. Tumor necrosis factor-alpha (TNF-alpha) and Acetylcholine (ACh) were also assessed using an immunohistochemical technique. RESULTS: Administration of TQ significantly improved cognition. In addition, TQ significantly increased SOD and TAC and decreased AChE activities. It also decreased MDA and NO levels as well as TNF-alpha immunoreactivity and increased BDNF and Bcl-2 levels as well as ACh immunoreactivity. DISCUSSION: Our results indicate that TQ prevents D-gal/AlCl3 induced cognitive decline by enhancing cholinergic function and synaptic plasticity as well as attenuation of oxidative damage, neuronal apoptosis, and neuroinflammation. These results indicate that TQ holds potential for neuroprotection and may be a promising approach for the treatment of neurodegenerative disorders. PMID- 29464989 TI - Removal of residual functionalized ionic liquids from water by ultrasound assisted zero-valent iron/activated carbon. AB - Numerous applications of ionic liquids (ILs) are often accompanied by the generation of aqueous wastes. Due to the high toxicity and poor biodegradability of ILs, effective chemical treatment is of great importance for their removal from aqueous solution. In this work, an ultrasound-assisted zero-valent iron/activated carbon (US-ZVI/AC) micro-electrolysis technique was used to degrade residual functionalized ILs, 1-butyl-3-methyl benzimidazolium bromide ([BMBIM]Br) and 1-allyl-3-methylimidazolium chloride ([AMIM]Cl) in aqueous solution, and the degradation degree, degradation kinetics and possible degradation pathways were investigated. It was shown that the degradation of these functionalized ILs was highly efficient in the US-ZVI/AC system, and the degradation degree was as high as 96.1% and 92.9% in 110 min for [BMBIM]Br and [AMIM]Cl, respectively. The degradation of [BMBIM]Br could be described by the second-order kinetics model, and [BMBIM]+ was decomposed in two ways: (i) sequential cleavage of N-alkyl side chain of the cation produced three intermediates; (ii) the 2-positioned H atoms of the benzimidazolium ring were first oxidized, and then the imidazolium ring was opened. The degradation of [AMIM]Cl followed the first-order kinetics rule, and the 2,4,5-positioned H atoms of the imidazolium ring were oxidized to induce ring opening. In addition, the removal of total organic carbon was found to be >87%, which indicates that most of the ILs was mineralized in the degradation process. These results suggest that ultrasound-assisted ZVI/AC micro-electrolysis is highly effective for the removal of residual functionalized ILs from aqueous environment.

The workplace affords good opportunities for learning, but the service-learning period may also impose stress on phycisians in specialization training. In medical work, social support has proved to be a very important factor in managing stress. Social support may afford advantages also for learning and professional identity building. However, little was known about how social support is perceived by doctors in specialization training. This study aimed to understand the perceptions of physicians in specialization training regarding social support communication in their workplace during their learning-through-service period. The study was conducted qualitatively by inductively analyzing the physicians' descriptions of workplace communication. The dataset included 120 essays, 60 each from hospitals and primary healthcare centres. Physicians in specialization training explained the need of social support with the responsibilities and demands of their clinical work and the inability to control and manage their workloads. They perceived that social support works well for managing stress, but also for strengthening relational ties and one's professional identity. A leader's support was perceived as being effective, and both senior and junior colleagues were described as an important source of social support. Also co workers, such as the individual nurse partner with whom one works, was mentioned as an important source of social support. The results of this study indicate that social support works at the relational and identity levels, which is due to the multi-functional nature of workplace communication. For example, consultation functions as situational problem-solving, but also the tone of social interaction is meaningful. Thus, strengthening one's professional identity or collegial relationships requires further attention to workplace communication. Abbreviations PiST: Physician in specialization training.

AB - There is a demand for interventions aimed at adolescent girls with psychosomatic problems. In 2013, positive results were reported from a dance intervention programme addressing girls with internalizing problems. The research team behind the intervention immediately received requests from municipalities and county councils interested in using the intervention. From an implementation point of view it is unclear what made the intervention spread without an active plan. The aim of this study was to explore adopters' experiences about the diffusion and initiation of a public health intervention targeting adolescent girls with internalizing problems. Interviews were conducted with 12 people who were engaged in initiating the intervention in different settings. Data were analysed using conventional content analysis, yielding three categories: perceived appeal and trustworthiness, convenient information, and contextual factors. The results reflected that the participants found that there was a need for an intervention and found the dance intervention to be evidence based and not too complex to perform. Further, there was available information on the project which could easily be distributed to decision makers and others. When initiating the intervention, factors related to economy, possibility for collaboration and recruitment were of importance.

AB - This study of Afton Chemical Corporation's Sauget facility and its International Chemical Workers Union Council (ICWUC) Local 871C demonstrates how significant safety improvements can be made when committed leadership from both management and union work together, build trust, train the entire work force in U.S. Occupational Safety and Health Administration 10-hour classes, and communicate with their work force, both salaried and hourly. A key finding is that listening to the workers closest to production can lead to solutions, many of them more cost-efficient than top-down decision-making. Another is that making safety and health an authentic value is hard work, requiring time, money, and commitment. Third, union and management must both have leadership willing to take chances and learn to trust one another. Fourth, training must be for everyone and ongoing. Finally, health and safety improvements require dedicated funding. The result was resolution of more than one hundred safety concerns and an ongoing institutionalized process for continuing improvement.

AB - It is commonly argued that a serious right to life is grounded only in actual, relatively advanced psychological capacities a being has acquired. The moral permissibility of abortion is frequently argued for on these grounds. Increasingly it is being argued that such accounts also entail the permissibility of infanticide, with several proponents of these theories accepting this consequence. We show, however, that these accounts imply the permissibility of even more unpalatable acts than infanticide performed on infants: organ harvesting, live experimentation, sexual interference, and discriminatory killing. The stronger intuitions against the permissibility of these 'pre personal acts' allow us to re-establish a comprehensive and persuasive reductio against psychological accounts of persons.

AB - Several automatic strategies for aeration control have been investigated so far to favor a significant decrement of energy consumptions in biological processes in wastewater treatment plants (WWTPs). Above all, the intermittent aeration process has demonstrated to have several advantages. This work reports the results of a case study made in a small municipal WWTP where an intermittent aeration control strategy based on the online measurement of real-time nitrogen forms has been implemented to optimize the nitrogen removal and the energy consumption in an activated process. High organic removal efficiency was achieved during the whole experimental period. Results indicated that nitrogen removal efficiency has been improved, especially during winter months, by the control strategy adopted that helped to determine the perfect length for the nitrification and denitrification phases. The intermittent aeration process increased the activity of the biomass, further selecting phosphate-accumulating bacteria and improving the growth of bacteria able to internally store carbon source. Excellent effects were achieved on energy and chemical consumption, with a reduction of about 15% and 23%, respectively. Finally, a 12% reduction of sludge production was also detected. PMID- 29464995 TI - Fabrication of calixarene-grafted magnetic nanocomposite for the effective removal of lead(II) from aqueous solution. AB - Magnetic nanocomposites adorned with calixarene were successfully prepared by immobilizing diethanolamine functionalized p-tert-butylcalix[4]arene (DEA-Calix) onto silica-coated magnetic nanoparticles (MNPs). The synthesis, surface morphology, purity, elemental composition and thermal stability of newly prepared nanocomposites were analyzed using FT-IR spectroscopy, scanning electron microscopy (SEM), energy dispersive spectroscopy (EDX), X-ray diffractometer (XRD), thermal gravimetric analysis (TGA) and vibrating sample magnetometer (VSM). Magnetic solid-phase adsorption (MSPA) was employed to explore the adsorption behavior of DEA-Calix-MNPs towards Pb(II) from water samples prior to its flame atomic absorption spectrometric analysis. The essential analytical factors governing the adsorption efficiency such as solution pH, mass of adsorbent, concentration and contact time have been investigated and optimized. The results depict that DEA-Calix-MNPs has excellent adsorption efficiency 97% (at pH 5.5) with high adsorption capacity of 51.81 mg g-1 for Pb(II) adsorption. Additionally, kinetic and equilibrium studies suggested that Pb(II) adsorption process follows a pseudo-second-order model and Langmuir isotherms, respectively. Real sample analysis also confirmed field applicability of the new DEA-Calix-MNPs adsorbent.

AB - This paper describes the search for procedures through which the xenobiotic pollutant diclofenac can be removed from non-sterile aquatic systems. Specifically, adsorption to solid supports (carriers) in combination with biodegradation by non-immobilized and immobilized white rot fungus Trametes versicolor were investigated. Batch experiments using polyurethane foam (PUF) carriers resulted in 99.9% diclofenac removal after 4 h, with monolayer adsorption of diclofenac to carrier and glass surfaces accounting for most of the diclofenac decrease. Enzymatic reactions contributed less, accounting for approximately < 0.5% of this decrease. In bioreactor experiments using PUF carriers, an initial 100% removal was achieved with biodegradation contributing approximately 7%. In batch experiments that utilized polyethylene-carriers with negligible immobilization of Trametes versicolor, a 98% total diclofenac removal was achieved after one week, with a biodegradation contribution of approximately 14%. Five novel enzyme-catalyzed biodegradation products were tentatively identified in the batch-wise and bioreactor experiments using full scan ultra high-performance liquid chromatography-quadrupole/time of flight mass spectrometry. Both reduction and oxidation products were found, with the contents estimated to be at ug L-1 concentration levels.

AB - Histone deacetylase 3 (HDAC3) is a potential target for the treatment of human diseases such as cancers, diabetes, chronic inflammation and neurodegenerative diseases. Previously, we proposed a virtual screening (VS) pipeline named "Hypo1_FRED_SAHA-3" for the discovery of HDAC3 inhibitors (HDAC3Is) and had thoroughly validated it by theoretical calculations. In this study, we attempted to explore its practical utility in a large-scale VS campaign. To this end, we used the VS pipeline to hierarchically screen the Specs chemical library. In order to facilitate compound cherry-picking, we then developed a knowledge-based pose filter (PF) by using our in-house quantitative structure activity relationship- (QSAR-) modelling approach and coupled it with FRED and Autodock Vina. Afterward, we purchased and tested 11 diverse compounds for their HDAC3 inhibitory activity in vitro. The bioassay has identified compound 2 (Specs ID: AN-979/41971160) as a HDAC3I (IC50 = 6.1 MUM), which proved the efficacy of our workflow. As a medicinal chemistry study, we performed a follow-up substructure search and identified two more hit compounds of the same chemical type, i.e. 2-1 (AQ-390/42122119, IC50 = 1.3 MUM) and 2-2 (AN-329/43450111, IC50 = 12.5 MUM). Based on the chemical structures and activities, we have demonstrated the essential role of the capping group in maintaining the activity for this class of HDAC3Is. In addition, we tested the hit compounds for their in vitro activities on other HDACs, including HDAC1, HDAC2, HDAC8, HDAC4 and HDAC6. We have identified these compounds are HDAC1/2/3 selective inhibitors, of which compound 2 show the best selectivity profile. Taken together, the present study is an experimental validation and an update to our earlier VS strategy. The identified hits could be used as starting structures for the development of highly potent and selective HDAC3Is.

AB - Hb New York or Hb Kaohsiung [beta113(G15)Val->Glu (GTG>GAG), HBB: c.341T>A] has been considered a rare beta hemoglobin (Hb) variant found originally in an Iranian woman and later in diverse populations but its genetic origin has not been elucidated. Here we report molecular and hematological descriptions of this variant found in the Thai population. Among 5643 subjects referred for hemoglobinopathy investigation during January 2015 to September 2017, 183 (3.2%) were found to carry several Hb variants, including beta chain variants (n = 135, 2.4%), alpha chain variants (n = 33, 0.6%), Hb Lepore-Hollandia (NG_000007.3: g.63290_70702del) and Hb Lepore-Boston-Washington (NG_000007.3: g.63632_71046del) (deltabeta hybrid Hb) (n = 12, 0.2%) and delta chain variants (n = 3, 0.05%). Of patients with beta chain variants, six with normal high performance liquid chromatography (HPLC) patterns, had an abnormal Hb in zone 11 of capillary electrophoresis (CE), the amounts of which ranged from 29.6-45.4% with normal levels of Hb A2 and Hb F. DNA analysis identified a heterozygous Hb New York mutation in all cases. Further screening of alpha-thalassemia (alpha-thal) identified coinheritance of alpha+- and alpha0-thal in two of them who had reduced levels of Hb New York. Haplotype analysis suggested that the Thai Hb New York was likely associated with a single beta-globin haplotype [+ - - - - + +], indicating that it was of the same origin. Hematological findings and simple DNA assay based on allele-specific polymerase chain reaction (PCR) for rapid detection of Hb New York are presented. PMID- 29465000 TI - Long non-coding RNA FENDRR reduces prostate cancer malignancy by competitively binding miR-18a-5p with RUNX1. AB - CONTEXT: Prostate cancer (PCa) is one of the most commonly diagnosed malignancy in men in the western world. OBJECTIVE: We aim to investigate the biological role of long non-coding RNA FENDRR and its mechanism in PCa. MATERIALS AND METHODS: We determined the expression of FENDRR and miR-18a-5p in PCa tissues and examined the regulatory mechanism in PCa cell lines. RESULTS: FENDRR transcripts in human PCa tissues were significantly decreased compared with the normal controls. Reduced expression of FENDRR was correlated with the increase of pathological degree and poor prognosis in PCa patients. Upregulation of FENDRR inhibited cell proliferation, increased apoptosis and decreased invasion and migration ability, which was inhibited by miR-18a-5p mimic. Knockdown of FENDRR resulted in a significant increase of PCa cell proliferation and decrease of apoptosis and this effect was inhibited miR-18a-5p inhibitor. FENDRR and RUNX1 contain potential target sites for miR-18a-5p. miR-18a-5p mimic inhibited RUNX1 expression and luciferase activity. FENDRR could increase RUNX1 expression, which was inhibited by miR-18a-5p. The effect of FENDRR on cell proliferation, apoptosis and invasion and migration ability was suppressed by silence of RUNX1. DISCUSSION AND CONCLUSION: These results position FENDRR/miR-18a-5p/RUNX1 as a potential therapeutic target and biomarker for PCa.

AB - PURPOSE: To revise and extend the previously published serum cotinine cut offs to classify smokers and non-smokers for US adolescents and adults. MATERIALS AND METHODS: Cross-sectional data (N = 10171) from National Health and Nutrition Examination Survey for 2011-2014 were used to compute serum cotinine cut-offs to classify smokers and non-smokers for US adults aged >=20 years and 2007-2014 (N = 4583) data were used to compute serum cotinine cut-offs for US adolescents aged 12-19 years. RESULTS: Specificities and sensitivities for the cut-offs among adults were >=95% and >=75% among adolescents. For adults, serum cotinine cut offs in ng/mL to classify smokers from non-smokers were 3.3 for the total population, 4.13 for males, 2.99 for females, 4.03 for non-Hispanic whites, 8.85 for non-Hispanic blacks, 0.377 for Mexican Americans, 1.72 for other Hispanics and 1.41 for non-Hispanic Asians. For adolescents, serum cotinine cut-offs in ng/mL to classify smokers from non-smokers were 0.765 for the total population, 1.1 for males, 0.408 for females, 1.2 for non-Hispanic whites, 1.98 for non Hispanic blacks, 0.215 for Mexican Americans and 0.321 for other Hispanics. CONCLUSIONS: Serum cotinine cut-offs to distinguish smokers from non-smokers for US adults and adolescents were developed.

AB - PURPOSE: The diagnostic and prognostic significance of procalcitonin remains uncertain in HF patients. We reviewed and performed a meta-analysis of studies that measured PCT in HF patients, with or without infection. MATERIALS AND METHODS: We identified seven studies (9514 patients, 5810 with diagnoses of HF) eligible for our analysis, out of 247 examined. We estimated the serum PCT concentrations in patients with and without HF and/or infection and examined the mortality rates of patients with versus without elevated serum PCT concentrations. RESULTS: The mean age of the study samples ranged between 58 and 81 years, the men proportion between 47% and 66%, the follow-up duration between 22 and 180 days. The median PCT concentration in patients with HF and concomitant infections tended to be higher (0.26 ng/l [0.06, 0.46]) than in patients with HF alone (0.10 ng/l [0.08, 0.12]; p = 0.059). The mortality of patients suffering from HF and whose serum PCT concentrations were elevated was significantly higher than that of patients suffering from HF whose PCT concentrations were normal at 30 (2.66 [1.74, 4.05]), 90 (2.12 [1.59, 2.83]) and 180 days (2.06 [1.13, 3.78]). CONCLUSIONS: In patients with HF, an elevated serum PCT concentration predicted the short-term risk of death.

PMID- 29465005 TI - Influence of airborne particulates on respiratory tract deposition of inhaled toluene and naphthalene in the rat. AB - OBJECTIVE: Most studies report that inhaled volatile and semivolatile organic compounds (VOCs/SVOCs) tend to deposit in the upper respiratory tract, while ultrafine (or near ultrafine) particulate matter (PM) (~100 nm) reaches the lower airways. The objective of this study was to determine whether carbon particle co exposure carries VOCs/SVOCs deeper into the lungs where they are deposited. MATERIALS AND METHODS: Male Sprague-Dawley rats were exposed by inhalation (nose only) to radiolabeled toluene (20 ppm) or naphthalene (20 ppm) on a single occasion for 1 h, with or without concurrent carbon particle exposure (~5 mg/m3). The distribution of radiolabel deposited within the respiratory tract of each animal was determined after sacrifice. The extent of adsorption of toluene and naphthalene to airborne carbon particles under the exposure conditions of the study was also assessed. RESULTS: We found that in the absence of particles, the highest deposition of both naphthalene and toluene was observed in the upper respiratory tract. Co-exposure with carbon particles tended to increase naphthalene deposition slightly throughout the respiratory tract, whereas slight decreases in toluene deposition were observed. Few differences were statistically significant. Naphthalene showed greater adsorption to the particles compared to toluene, but overall the particle-adsorbed concentration of each of these compounds was a small fraction of the total inspired concentration. CONCLUSIONS: These studies imply that at the concentrations used for the exposures in this study, inhaled carbon particles do not substantially alter the deposition of naphthalene and toluene within the respiratory tract.

AB - Hyperandrogenic state in females is accompanied with metabolic syndrome, insulin resistance and vascular pathologies. A total of 67%-85% of hyperandrogenic women suffer also from vitamin D deficiency. We aimed to check a potential interplay between hyperandrogenism and vitamin D deficiency in producing insulin resistance and effects on coronary resistance arteries. Adolescent female rats were divided into four groups, 11-12 animals in each. Transdermal testosterone-treated and vehicle-treated animals were kept either on vitamin D-deficient or on vitamin D supplemented diet for 8 weeks. Plasma sexual steroid, insulin, leptin and vitamin D plasma levels were measured, and oral glucose tolerance test was performed. In coronary arterioles, insulin receptor and vitamin D receptor expressions were tested by immunohistochemistry, and insulin-induced relaxation was measured in vitro on isolated coronary resistance artery segments. Testosterone impaired glucose tolerance, and it diminished insulin relaxation but did not affect the expression of insulin and vitamin D receptors in vascular tissue. Vitamin D deficiency elevated postprandial insulin levels and homeostatic model assessment insulin resistance. It also diminished insulin-induced coronary arteriole relaxation, while it raised the expression of vitamin D and insulin receptors in the endothelial and medial layers. Our conclusion is that both hyperandrogenism and vitamin D deficiency reduce sensitivity of coronary vascular tissue to insulin, but they do it with different mechanisms. PMID- 29465006 TI - Probiotic effects of anaerobic co-digestion substrates. AB - Manure is often added to stabilise anaerobic digesters especially when co digesting high-energy substrates such as whey. While different researchers have attributed its beneficial effect to various components including alkalinity, nutrients or trace elements this research instead aimed to determine whether microorganisms, such as lactic acid bacteria which are naturally present in the feedstocks, were having a notable beneficial effect on biogas production. Casein whey and cow manure were co-digested with primary sludge and produced 151.1% biogas compared to the control reactor digesting primary sludge alone. It was found that targeting the microorganisms in the manure via autoclaving decreased reactor performance to only 112.8% compared to the control potentially indicating that the manure is providing a probiotic effect. It was also found that storing casein whey (which is needed to balance out its seasonal production peaks) produces microorganisms that play a similarly important role as evidenced by the decrease in performance from 151.1% to 112.9% when they were removed via filtration. PMID- 29465007 TI - The Necrotrophic Fungus Macrophomina phaseolina Promotes Charcoal Rot Susceptibility in Grain Sorghum Through Induced Host Cell-Wall-Degrading Enzymes. AB - The cell-wall-degrading enzymes (CWDE) secreted by necrotrophs are important virulence factors. Although not unequivocally demonstrated, it has been suggested that necrotrophs induce hosts to cooperate in disease development through manipulation of host CWDE. The necrotrophic fungus Macrophomina phaseolina causes charcoal rot disease in Sorghum bicolor. An RNA-seq experiment was conducted to investigate the behavior of sorghum CWDE-encoding genes after M. phaseolina inoculation. Results revealed M. phaseolina's ability to significantly upregulate pectin methylesterase-, polygalacturonase-, cellulase-, endoglucanase-, and glycosyl hydrolase-encoding genes in a charcoal rot-susceptible sorghum genotype (Tx7000) but not in a resistant genotype (SC599). For functional validation, crude enzyme mixtures were extracted from M. phaseolina- and mock-inoculated charcoal-rot-resistant (SC599 and SC35) and -susceptible (Tx7000 and BTx3042) sorghum genotype stalks. A gel diffusion assay (pectin substrate) revealed significantly increased pectin methylesterase activity in M. phaseolina inoculated Tx7000 and BTx3042. Polygalacturonase activity was determined using a ruthenium red absorbance assay (535 nm). Significantly increased polygalacturonase activity was observed in two susceptible genotypes after M. phaseolina inoculation. The activity of cellulose-degrading enzymes was determined using a 2-cyanoacetamide fluorimetric assay (excitation and emission maxima at 331 and 383 nm, respectively). The assay revealed significantly increased cellulose-degrading enzyme activity in M. phaseolina-inoculated Tx7000 and BTx3042. These findings revealed M. phaseolina's ability to promote charcoal rot susceptibility in grain sorghum through induced host CWDE. PMID- 29465009 TI - The Top 50 Most Cited Publications in Disability Sport: A Bibliometric Analysis. AB - Despite increasing publications in disability sport, no bibliometric analysis has been conducted to evaluate their impact.We conducted a systematic search of theWeb of Science Core Collection citation index on June 26, 2017 for publications published since 1980 to identify the top 50 most cited publications in disability sport. The top 50 cited publications were mainly articles and reviews published in the English language between 1993 and 2014. Most of the 148 authors who contributed to these publications were based in Europe and North America. The majority of the publications can be categorized as sociological and psychological as well as training and competition effects. The most researched events were the Paralympics and Special Olympics. These top-cited publications have contributed to the development of disability sport research. PMID- 29465008 TI - Genetic variations in genes of the stress response pathway are associated with prolonged abstinence from heroin. AB - AIM: This study assesses whether genetic variants in stress-related genes are associated with prolonged abstinence from heroin in subjects that are not in long term methadone treatment. METHODS: Frequencies of 117 polymorphisms in 30 genes were compared between subjects with history of heroin addiction, either without agonist treatment (n = 129) or in methadone maintenance treatment (n = 923). RESULTS: SNP rs1500 downstream of CRHBP and an interaction of SNPs rs10482672 (NR3C1) and rs4234955 (NPY1R/NPY5R) were significantly associated with prolonged abstinence without agonist treatment. CONCLUSION: This study suggests that variability in stress-related genes may contribute to the ability of certain subjects to remain in prolonged abstinence from heroin, possibly due to higher resilience to stress.

AB - Polycyclic aromatic hydrocarbons (PAHs) and potentially toxic trace elements (PTEs) soil contamination have become areas of concern. Bioaugmentation is regarded as an effective bioremediation method, however it is difficult to simultaneously degrade organic compounds and remove PTEs with individual microbial strains. Therefore, the objective of this study was to evaluate the feasibility of using immobilized microbial consortia, including two PAH-degrading bacterial strains (W1 and W2) and a Cr(VI)-reducing bacterium (Y2), for the remediation of pyrene-Cr(VI) co-contaminated soil. Three immobilization methods were investigated: (1) bacterial consortium adsorption onto biochar (BC), (2) bacterial consortium entrapment in alginate beads (AC), (3) bacterial consortium adsorption on biochar and sequential entrapment in alginate beads (BAC). In addition, a free bacterial consortium (FC) was also used for comparison. Ten treatments were designed to illustrate the bioremediation efficiency of the free and immobilized consortia. The results show that treatments AC and BAC resulted in more efficient Cr(VI) removal compared with BC and FC. Pyrene levels in AC and BAC microcosms were reduced from 42.33 +/- 3.82 to 11.56 +/- 1.37 and 7.48 +/- 0.39 mg kg-1, respectively. Bioavailable Cr (VI) in AC and BAC was significantly lower than that in other microcosms after 28 days' incubation. Both AC and BAC microcosms exhibited a higher level of dehydrogenase and fluorescein diacetate hydrolysis activity. Furthermore, soil microbial diversity was higher in AC and BAC microcosms compared with the others. Thus, the entrapped consortia may be useful for bioremediation of pyrene and Cr (VI) without compromising soil ecology. PMID- 29465024 TI - A prospective study of women with ASCUS or LSIL pap smears at baseline and HPV E6/E7 mRNA positive: a 3-year follow-up. AB - Human papillomavirus (HPV) testing is used in the triage of women with a borderline smear result. The efficiency of testing women with a low-grade squamous intraepithelial lesion (LSIL) and atypical squamous cells of undetermined significance (ASCUS) is less clear. For this reason we used a new HPV test that detects E6/E7 messenger RNA (mRNA), which might have a higher specificity. The objective of this prospective study was to assess whether HPV E6/E7 mRNA positivity in women with ASCUS and LSIL at baseline, is able to predict those women who have a high risk of developing a histological cervical intraepithelial neoplasia (CIN2) or worse lesion. We took into consideration the women's age and HPV DNA genotype and followed them up for 3 years. Cervical samples from women with high-risk HPV (HR-HPV) DNA-positive ASCUS (n = 90) or LSIL (n = 222) were tested for the presence of HR-HPV E6/E7 mRNA and the women were monitored for the development of histopathologically verified CIN2+. Thirteen patients with ASCUS and 17 with LSIL did not complete follow-up. All patients with LSIL and ASCUS, enrolled in this study, had confirmed lesions at the colposcopic examination. Follow-up was available for 312 women, 193 were positive in the HR-HPV DNA test and 93 had a HPV E6/E7 mRNA positive test. Finally, 22 women positive in the HPV DNA test for high-risk genotypes and with positive E6/E7 mRNA had a histologically confirmed CIN2+. Only two cases with negative HPV E6/E7 mRNA had CIN2+. The study shows that women positive in the HPV E6/E7 mRNA test have a greater risk of malignant progression of cervical lesions and therefore deserve greater attention and earlier check-ups. PMID- 29465025 TI - Swift and Low-Cost Surge in Chemical Threat Response: Is It Possible? The Experience of a French Hospital. AB - In 2016 France hosted the European football championship. In a context of an increased terrorist threat, Chemical, Bacteriological, Radiological, Nuclear (CBRN) attacks were considered possible. Three days prior to the beginning of the event, the Health Authorities required that a medium sized hospital close to a major potential target, prepare a chemical decontamination centre. Despite a low level of preparedness, little external help, and very few extra resources, an efficient decontamination chain (all premises necessary for the management of contaminated victims: from the entrance gate to the post-decontamination dressing cabins) was set up in 15 days (12 days after the unrealistic deadline). Numerous practical measures allowed three persons in CBRN personal protective equipment (PPE) to manage the whole chain, providing a maximum flow of 24 persons/hour. Volunteers were trained in PPE dressing, undressing and in decontamination procedures. This experience, offers a novel paradigm in managing chemical decontamination, in terms of attitude, and with adaptations to overcome practical constraints. It demonstrates that it is possible to set up a decontamination chain rapidly at very low cost. This provides an attractive option for less advanced countries and in humanitarian contexts. Some additional refinements, enhancements may be considered to further improve results. (Disaster Med Public Health Preparedness. 2018;12:649-656). PMID- 29465026 TI - Great boast, small roast on effects of selective serotonin reuptake inhibitors: response to a critique of our systematic review. AB - Our systematic review in BMC Psychiatry concluded that selective serotonin reuptake inhibitors (SSRIs) compared with placebo significantly increase the risk of serious adverse events (SAEs) in patients with major depression and the potential beneficial effects of SSRIs seem to be outweighed by the harms. Hieronymus et al. accused us of methodological inaccuracies and blatant errors. In their post-hoc analysis of our data, they reported that SSRIs only increase the risk of SAEs in elderly and seems safe for non-elderly patients. They also found our review misleading because our efficacy analyses were based on the 17 item Hamilton Depression Rating Scale; we included suboptimal SSRI doses; and we missed some 'pivotal trials'. We do not agree with Hieronymus et al. regarding several of the 'errors' they claim that we have made. However, we acknowledge that they have identified minor errors and that we missed some trials. After rectifying the errors and inclusion of the missed trials by us and Hieronymus et al., we re-analysed the data. The updated analyses are even more robust and confirm our earlier conclusions. SSRIs significantly increase the risk of an SAE both in non-elderly (p=0.045) and elderly (p=0.01) patients [overall odds ratio 1.39; 95% confidence interval (CI) 1.13 to 1.73; p=0.002; I2=0%]. Moreover, SSRIs did not change noticeably the 17-item Hamilton Depression Rating Scale, the internationally accepted scale (mean difference -2.02 points; 95% CI -2.38 to 1.66; p<0.00001). We found no differential effect of dose (p=0.20). PMID- 29465028 TI - ICTV Virus Taxonomy Profile: Rhabdoviridae. AB - The family Rhabdoviridae comprises viruses with negative-sense (-) single stranded RNA genomes of 10.8-16.1 kb. Virions are typically enveloped with bullet shaped or bacilliform morphology but can also be non-enveloped filaments. Rhabdoviruses infect plants and animals including mammals, birds, reptiles and fish, as well as arthropods which serve as single hosts or act as biological vectors for transmission to animals or plants. Rhabdoviruses include important pathogens of humans, livestock, fish and agricultural crops. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the taxonomy of Rhabdoviridae, which is available at www.ictv.global/report/rhabdoviridae. PMID- 29465027 TI - Correlation between measles vaccine doses: implications for the maintenance of elimination. AB - Measles eradication efforts have been successful at achieving elimination in many countries worldwide. Such countries actively work to maintain this elimination by continuing to improve coverage of two routine doses of measles vaccine following measles elimination. While improving measles vaccine coverage is always beneficial, we show, using a steady-state analysis of a dynamical model, that the correlation between populations receiving the first and second routine dose also has a significant impact on the population immunity achieved by a specified combination of first and second dose coverage. If the second dose is administered to people independently of whether they had the first dose, high second-dose coverage improves the proportion of the population receiving at least one dose, and will have a large effect on population immunity. If the second dose is administered only to people who have had the first dose, high second-dose coverage reduces the rate of primary vaccine failure, but does not reach people who missed the first dose; this will therefore have a relatively small effect on population immunity. When doses are administered dependently, and assuming the first dose has higher coverage, increasing the coverage of the first dose has a larger impact on population immunity than does increasing the coverage of the second. Correlation between vaccine doses has a significant impact on the level of population immunity maintained by current vaccination coverage, potentially outweighing the effects of age structure and, in some cases, recent improvements in vaccine coverage. It is therefore important to understand the correlation between vaccine doses as such correlation may have a large impact on the effectiveness of measles vaccination strategies.

AB - WalRK is an essential two-component signal transduction system that plays a central role in coordinating cell wall synthesis and cell growth in Bacillus subtilis. However, the physiological role of WalRK and its essentiality for growth have not been elucidated. We investigated the behaviour of WalRK during heat stress and its essentiality for cell proliferation. We determined that the inactivation of the walHI genes which encode the negative modulator of WalK, resulted in growth defects and eventual cell lysis at high temperatures. Screening of suppressor mutations revealed that the inactivation of LytE, an dl endopeptidase, restored the growth of the DeltawalHI mutant at high temperatures. Suppressor mutations that reduced heat induction arising from the walRK regulon were also mapped to the walK ORF. Therefore, we hypothesized that overactivation of LytE affects the phenotype of the DeltawalHI mutant. This hypothesis was corroborated by the overexpression of the negative regulator of LytE, IseA and PdaC, which rescued the growth of the DeltawalHI mutant at high temperatures. Elucidating the cause of the temperature sensitivity of the DeltawalHI mutant could explain the essentiality of WalRK. We proved that the constitutive expression of lytE or cwlO using a synthetic promoter uncouples these expressions from WalRK, and renders WalRK nonessential in the pdaC and iseA mutant backgrounds. We propose that the essentiality of WalRK is derived from the coordination of cell wall metabolism with cell growth by regulating dl endopeptidase activity under various growth conditions. PMID- 29465030 TI - Novel host restriction factors implicated in HIV-1 replication. AB - Human immunodeficiency virus-1 (HIV-1) is known to interact with multiple host cellular proteins during its replication in the target cell. While many of these host cellular proteins facilitate viral replication, a number of them are reported to inhibit HIV-1 replication at various stages of its life cycle. These host cellular proteins, which are known as restriction factors, constitute an integral part of the host's first line of defence against the viral pathogen. Since the discovery of apolipoprotein B mRNA-editing enzyme 3G (APOBEC3G) as an HIV-1 restriction factor, several human proteins have been identified that exhibit anti-HIV-1 restriction. While each restriction factor employs a distinct mechanism of inhibition, the HIV-1 virus has equally evolved complex counter strategies to neutralize their inhibitory effect. APOBEC3G, tetherin, sterile alpha motif and histidine-aspartate domain 1 (SAMHD1), and trim-5alpha are some of the best known HIV-1 restriction factors that have been studied in great detail. Recently, six novel restriction factors were discovered that exhibit significant antiviral activity: endoplasmic reticulum alpha1,2-mannosidase I (ERManI), translocator protein (TSPO), guanylate-binding protein 5 (GBP5), serine incorporator (SERINC3/5) and zinc-finger antiviral protein (ZAP). The focus of this review is to discuss the antiviral mechanism of action of these six restriction factors and provide insights into the probable counter-evasion strategies employed by the HIV-1 virus. The recent discovery of new restriction factors substantiates the complex host-pathogen interactions occurring during HIV 1 pathogenesis and makes it imperative that further investigations are conducted to elucidate the molecular basis of HIV-1 replication.

A CT scan showed no cerebral or ophthalmic injury. However, the patient was persistently apathic with head- and gaze direction towards the left and a facial nerve palsy. An MRI showed a linear intracerebral lesion stretching through pons into the cerebellar vermis. The patient had neuropaediatric rehabilitation and recovered fully within months.

The result showed Mycobacterium abscessus. Hence, cephalexin administration was instituted, but the ulcer did not heal, and it was excised. The subsequent healing was rapid. Mycobacterial infections in Denmark are rare, serious, and often resistant to antibiotics. PMID- 29465037 TI - Risk factors of peritonitis during early peritoneal dialysis in patients with ANCA-associated systemic vasculitis?. AB - This study investigated the risk factors of peritonitis during early peritoneal dialysis for renal failure in patients with antineutrophil cytoplasmic antibody (ANCA)-associated systemic vasculitis (AASV). This study enrolled hospitalized AASV patients with renal failure who underwent peritoneal dialysis at the Department of Nephrology of our hospital between 2008 and 2015. The primary aim of this study was to perform a retrospective analysis to characterize peritonitis during the early period (<= 8 weeks) of dialysis, and to compare the differences in initial clinical manifestations, vasculitis activity, immunosuppressive therapies prior to the renal replacement therapy, and prognosis between patients with or without peritonitis. The secondary aim of this study was to conduct a literature review of peritoneal dialysis in patients with vasculitis. All 14 enrolled AASV patients had myeloperoxidase (MPO)-positive microscopic polyangiitis (MPA). Six patients (of whom 2 died) withdrew from peritoneal dialysis due to peritonitis caused by enteric bacteria during the early period of dialysis. Their mean Birmingham vasculitis activity score (BVAS) during the early AASV onset was 31.67 +/- 3.98, with significant symptoms of gastrointestinal involvement. Also, their BVAS score, anti-MPO antibody titer, erythrocyte sedimentation rate, C-reactive protein level, serum ANCA level, and glucocorticoid dose were higher than the AASV patients without peritonitis (all p < 0.05). AASV patients with a higher level of vasculitis (BVAS score > 30) during onset as well as gastrointestinal symptoms had a higher risk for intestinal peritonitis. Therefore, peritoneal dialysis is not recommended as a first-choice renal replacement therapy for such patients.?.

AB - Interface roughness scattering (IRS) is one of the major scattering mechanisms limiting the performance of non-planar multi-gate transistors, like Fin field effect transistors (FETs). Here, two physical models (Ando's and multi-sub-band) of electron scattering with the interface roughness induced potential are investigated using an in-house built 3D finite element ensemble Monte Carlo simulation toolbox including parameter-free 2D Schrodinger equation quantum correction that handles all relevant scattering mechanisms within highly non equilibrium carrier transport. Moreover, we predict the effect of IRS on performance of FinFETs with realistic channel cross-section shapes with respect to the IRS correlation length (Lambda) and RMS height ([Formula: see text]). The simulations of the n-type SOI FinFETs with the multi-sub-band IRS model shows its very strong effect on electron transport in the device channel compared to the Ando's model. We have also found that the FinFETs are strongly affected by the IRS in the ON-region. The limiting effect of the IRS significantly increases as the Fin width is reduced. The FinFETs with [Formula: see text] channel orientation are affected more by the IRS than those with the [Formula: see text] crystal orientation. Finally, Lambda and [Formula: see text] are shown to affect the device performance similarly. A change in values by 30% (Lambda) or [Formula: see text] ([Formula: see text]) results in an increase (decrease) of up to [Formula: see text] in the drive current.

AB - Despite intensive investigations into the Verwey phase transition of Fe3O4 over half a century, the mechanism of this phase transition remains controversial and needs further research. In this work, we build the Fe3O4/SrTiO3 multiferroic heterostructure and investigate the temperature dependence of its saturation magnetization under various electric fields. It is found that the charge screening effect not only influences the magnetization but also induces the temperature of the Verwey phase transition shifting ~13 K. It suggests that the Verwey phase transition has certain correlations with the electron distribution and the change of the number of minority spin electrons in the trimerons plays a dominant role in the temperature shift of the phase transition.

AB - Recently topological materials have attracted much attention due to their quantization transports as well as edge states. It will be excellent to realize the robust quantum anomalous Hall transports in graphene-based devices. Using density-functional theory and tight-binding method, we investigated the structural, magnetic and topological properties for the boron-doped graphene with Re-adsorption. A large band-gap of 32.5 meV is opened by the Rashba spin-orbital coupling, and the band-gap is robust against the shape deformation of +/ [Formula: see text] along the zigzag direction. Giant magnetic anisotropy emerges in this adsorption system together with the Fermi level lying in the band gap. Both the magnetic anisotropy and the band gap can be tuned by a moderate electric field. Calculations reveal that the system exhibits the quantization transports with the Chern number [Formula: see text].

AB - As it approaches the glass transition, particle motion in liquids becomes highly heterogeneous and regions with virtually no mobility coexist with liquid-like domains. This complex dynamic is believed to be responsible for different phenomena including non-exponential relaxation and the breakdown of the Stokes Einstein relation. Understanding the relationships between dynamical heterogeneities and local structure in metallic liquids and glasses is a major scientific challenge. Here we use classical molecular dynamics simulations to study the atomic dynamics and microscopic structure of [Formula: see text] alloy in the supercooling regime. Dynamical heterogeneities are identified via an isoconfigurational analysis. We demonstrate the transition from isolated to clustering low mobility with decreasing temperature. These slow clusters, whose sizes grow upon cooling, are also associated with concentration fluctuations, characterized by a Zr-enriched phase, with a composition [Formula: see text]. In addition, a structural analysis of slow clusters based on Voronoi tessellation evidences an increase with respect of the bulk system of the fraction of Cu atoms having a local icosahedral order. These results are in agreement with the consolidated scenario of the relevant role played by icosahedral order in the dynamic slowing-down in supercooled metal alloys.

AB - Room-temperature superparamagnetism due to a large magnetic anisotropy energy (MAE) of a single atom magnet has always been a prerequisite for nanoscale magnetic devices. Realization of two dimensional (2D) materials such as single layer (SL) MoS2, has provided new platforms for exploring magnetic effects, which is important for both fundamental research and for industrial applications. Here, we use density functional theory (DFT) to show that the antisite defect (Mo S ) in SL MoS2 is magnetic in nature with a magnetic moment MU of ~2 [Formula: see text] and, remarkably, exhibits an exceptionally large atomic scale MAE [Formula: see text] of ~500 meV. Our calculations reveal that this giant anisotropy is the joint effect of strong crystal field and significant spin-orbit coupling (SOC). In addition, the magnetic moment MU can be tuned between 1 [Formula: see text] and 3 [Formula: see text] by varying the Fermi energy [Formula: see text], which can be achieved either by changing the gate voltage or by chemical doping. We also show that MAE can be raised to ~1 eV with n-type doping of the MoS2:Mo S sample. Our systematic investigations deepen our understanding of spin-related phenomena in SL MoS2 and could provide a route to nanoscale spintronic devices. PMID- 29465043 TI - The Intraoral Ultrasonography in Dentistry. AB - Ultrasonography (USG) is a diagnostic method that the ultrasonic image is created by ultrahigh-frequency sound waves, which have an acoustic frequency above the threshold of human hearing. Compared to other medical imaging methods, USG has several advantages of being real time, portable, inexpensive, radiation free, and noninvasive. In the medicine, most of the USG applications are transcutaneous. However, intraoral USG has been a relatively rare application, it has recently been drawing more interest. Intraoral USG is also used in dentistry for examining the salivary glands and ducts, as well as the mouth floor, the buccal, labial, and palatal mucosa, the tongue, periodontal tissues, and periapical lesions. The main purpose of this review is to provide detailed information about intraoral USG applications in dentistry. PMID- 29465044 TI - Antimicrobial Effect of Toothpastes Containing Fluoride, Xylitol, or Xylitol Probiotic on Salivary Streptococcus mutans and Lactobacillus in Children. AB - Aim: This in vivo study was designed to compare the antimicrobial effect of toothpastes containing fluoride, xylitol, or xylitol-probiotic on Streptococcus mutans and Lactobacillus in 13-15-year-old children. Materials and Methods: The study consisted of 60 pediatric patients who were randomly divided into three groups of 20 each. Group 1 recieved fluoride toothpaste (Colgate Max Fresh), group 2 used xylitol toothpaste (Xyliwhite), and group 3 used xylitol-probiotic toothpaste (PerioBiotic). Participants were asked to use the allocated dentifrice two times a day for 6 weeks. We performed tests on the saliva samples at the beginning of the study and after 6 weeks' duration following the use of toothpaste. The Statistical Package for the Social Sciences version 15 software and chi-square test were used for data analysis. Results: PerioBiotic toothpaste and Colgate Max Fresh toothpaste showed significant reduction in the number of participants who, prior to commencing the study, were diagnosed with a high number of cariogenic bacteria. On the contrary, no significant changes were observed with respect to the number of participants with a very high number of S. mutans and Lactobacillus on Xyliwhite toothpaste group. Conclusion: In the light of the data obtained in this in-vivo study, a new innovational aspect has been reached in the use of probiotics to ensure the balance between bacterial flora in the oral cavity. In daily routine, the administration of probiotics to children is difficult. The toothpaste can be used as a vehicle to transport probiotics to children's mouth. PMID- 29465045 TI - Sugammadex Improves Neuromuscular Function in Patients Receiving Perioperative Steroids. AB - Context: Sugammadex has steroid-encapsulating effect. Aim: This study was undertaken to assess whether the clinical efficacy of sugammadex was altered by the administration of steroids. Setting and Design: Sixty patients between 18 and 60 years of age with the American Society of Anesthesiologists I-IV and undergoing elective direct laryngoscopy/biopsy were included in this study. Materials and Methods: Patients were assigned to two groups based on the intraoperative steroid use: those who received steroid (Group S) and who did not (Group C). After standard general anesthesia, patients were monitored with the train of four (TOF) monitoring. The preferred steroid and its dose, timing of steroid administration, and TOF value before and after sugammadex as well as the time to recovery (TOF of 0.9) were recorded. Statistical Analysis Used: SPSS software version 17.0 was used for statistical analysis. Results: There is no statistically significant difference between groups in terms of age, gender, preoperative medication use, and TOF ratio just before administering sugammadex. The reached time to TOF 0.9 after sugammadex administration was significantly shorter in Group S than Group C (P < 0.05). A within-group comparison in Group S showed no difference in TOF ratio immediately before sugammadex as well as the dose of sugammadex in those who received prednisolone; time to TOF 0.9 was higher in prednisolone receivers as compared to dexamethasone receivers (P < 0.05). Conclusion: In patients receiving steroids, and particularly dexamethasone, an earlier reversal of neuromuscular block by sugammadex was found, in contrast with what one expect. Further studies are required to determine the cause of this effect which is probably due to a potential interaction between sugammadex and steroids. PMID- 29465046 TI - Clinical and Laboratory Features of Metformin Intoxication in Suicidal Patients Attending an Intensive Care Unit. AB - Introduction: This study has been performed for the purpose of researching the complications occurred at patients who took metformin overdose in an attempt to suicide. None of the patients has the diagnosis of diabetes mellitus and never used metformin. Materials and Methods: This retrospective cross-sectional study was carried out with 21 patients who has neither diagnosed diabetes mellitus nor taken metformin for suicide before. Results: It was observed that there is a moderate, negative (r = -0.63) statistically significant correlation (P < 0.001) between the time of applying to the hospital and arterial blood pH at the arrival and a statistically significant positive mild correlation (P < 0.041) between applying and blood lactate level (r = 0.45), and a moderate positive (r = 0.63) and statistically significant correlation (P < 0.001) between the total metformin dose and blood lactate level at the arrival and a positive, moderate (r = 0.68) significant correlation (P < 0.001) between the creatinine and metformin dose at the arrival. Lactic acidosis has been detected at 8 of 21 patients, 6 patients were hemodialized, 2 patients needed mechanical ventilation, and 2 patients died. It is observed that there is no mortality for early hemodialized patients. Conclusion: The most important reason of the mortality in patients who has metformin intoxication is metformin-associated lactic acidosis (MALA). It was considered that hemodialysis therapy could be effective in MALA. PMID- 29465047 TI - Knowledge and Practice of Standard Precautions by Health-Care Workers in a Tertiary Health Institution in Enugu, Nigeria. AB - Background: Standard precautions (SPs) are crucial in protecting both health-care workers (HCWs) and patients from nosocomial infections. This study assessed the knowledge and practices of SP among HCWs in tertiary health-care facilities. Methods: : This descriptive study was done in October 2014 among 629 HCWs at the University of Nigeria Teaching Hospital, Ituku-Ozalla, Enugu State. A pretested questionnaire was used and analysis done using SPSS version 13. Results: The HCWs studied were 629, mostly females (64.4%), married (62.3%), Christians (94%), and within 20-59 years. Majority were nurses (46.1%) working in the wards. Over 90% of respondents had heard of SP, mainly from formal training (62%). Over 70% could define SP, 74.6% had knowledge of when SP is needed and> 70% identified most components of SP. Over 90% agreed that SPs are useful and that employers should provide SP training. Most respondents washed hands after removal of gloves (73.6%) and before leaving patient's care area (33.1%). More than 70% had been exposed to patient's body fluids and washed the exposed part with water, soap, and disinfectant (52.1%). Gloves were the most commonly used personal protective equipment (PPE) (53.4%) and the major reason for inconsistent use was irregular access (57.7%). Over 50% recap needles before discarding. Exposure to patients' serum was significantly higher among doctors and nurses P < 0.05, while the use of PPEs was highest among the laboratory scientists (82.4%). Those who were trained on SP (70.8%) and PPE (69.7) were significantly more likely to use PPEs, P < 0.05. Conclusions: SP training and regular provision of PPEs are vital in compliance to SP. PMID- 29465048 TI - Evaluation of Teeth Development in Unilateral Cleft Lip and Palate Patients in Mixed Dentition by Using Medical Image Control Systems. AB - Objectives: The aim of this study was to evaluate the crown and root development in patients with cleft lip and palate using medical software programmes. Materials and Methods: In our study, 25 patients with mixed dentition unilateral cleft lip and palate were examined with cone-beam computed tomography (CBCT). The tomography images obtained as high resolution medical images on the computer control system (MIMICS 15.0, Materialise, Leuven, Belgium and SOLIDWORKS 2014 Premium, Concord, Massachusetts) were converted to three-dimensional volumetric images. These three-dimensional images of the cleft on the sides of the teeth in the crown and root growth were measured by mesiodistal length and crown/root rate with volume and area. These measurements were compared with a control group of healthy individuals. Results: There were no statistically significant differences in the volume, surface area and MD size, crown/root ratio of central incisor, canine, first premolar and second premolar teeth within defect, and healthy teeth. However, it was found that there was a significant difference between the volume, surface area and MD size, and crown/root ratio of the lateral teeth in each group. Conclusion: In particular, among patients with cleft lip and palate, on obtaining a solid model of the tooth structure by using these programs, tooth development can be examined in more detail, diagnosis can be made more reliable, as well as in treatment planning. We believe that these programs can be used to resolve certain limitations such as a lack of an application to be used in routine dental treatment and in particular the need to do more study. PMID- 29465049 TI - The Effect on Survival and Mortality of the Highest SUVmax Value on Metastatic Foci in Postoperative Kidney Tumors. AB - Objective: One-third of patients newly diagnosed with a kidney tumor have metachoronous disease, 25-50% have synchronous metastasis, and approximately 30 40% of patients have metastasis at the time of diagnosis. Metastasis mostly occurs in the lungs, regional lymph nodes, bones, and liver. The present study was aimed to determine the effect on mortality the values of standard uptake value (SUV)max measured with positron emission tomography (PET) in metastases of kidney tumors. Material and Methods: A retrospective review was conducted of the files of 77 patients newly diagnosed with kidney tumor and disease staging determined with PET in the Nuclear medicine Department of Saglik Bilimleri University Diyarbakir Gazi Yasargil Training and Research Hospital between August 2007 and April 2012. The gender, age, histological types, metastases, SUVmax values, and dates of death of the patients were recorded in the SPSS software. Results: It was observed that higher SUVmax values indicated a shorter survival time (r = .303) (P = 0.022). Patients with metastasis lived for a shorter period (P < 0.001), particularly those with liver metastasis (r = .515) (P = 0.049). Metastases were most frequently seen in lymph nodes (42.1%); the SUVmax values of lung metastases were higher (P = 0.025) and papillary carcinomas showed higher SUVmax uptake (P = 0.015). Conclusions: In the present study, it was concluded that the higher the SUVmax value the shorter the survival time. The survival time of patients with metastasis was shorter, and this could be estimated through the measured SUVmax values. PMID- 29465050 TI - Antibacterial Effect of Surface Pretreatment Techniques against Streptococcus Mutans. AB - Objective: The aim of this study was to evaluate the antibacterial surface pretreatment methods against Streptococcus mutans within the infected dentin surface using a tooth cavity model. Material and Methods: Seventy-two cavities were prepared on caries-free third molars (n = 8). After sterilization, teeth were inoculated with S. mutans for 48 h. One cavity of each tooth was used to evaluate the infection. Following inoculation, infected cavity surfaces were treated either with (1) Er:YAG Laser (1W; 5x5s, Smart 2940D Plus, Deka Laser), (2) Ozone (80s; HealOzone, Kavo), (3) ErYAG-Ozone combination, (4) Er:YAG-Ozone CHX combination, (5) Chlorhexidine (CHX), (6) Clearfil Protect Bond (PB), (7) potassium-titanyl-phosphate (KTP) Laser (1W; 60 s, SMARTLITE D, Deka Laser), (8) KTP-Ozone combination, and (9) KTP-Ozone-CHX. Standardized amounts of dentin chips were obtained from the cavity walls, and the number of bacteria recovered was counted. Kruskal-Wallis test was used for statistical analyzes. Results: Both sole antibacterial materials, CHX or Protect Bond application, exhibited the most effective antibacterial activity with 125 and 156 CFU is an acronym of "colony forming unit" usullay mentioned by acronym. (CFU/ml), respectively, among the groups evaluated (P < 0.05). Er:YAG laser irradiation and its combinations with other antibacterial surface pretreatment applications also inhibited the bacterial growth with, respectively, 1444, 406, and 294 CFU/ml bacterial recovery being more efficient than KTP laser irradiation and ozone combinations. Conclusions: As an alternative device with photodynamic effects, Er:YAG and KTP laser irradiations and their further combinations during the cavity pretreatment procedure with chlorhexidine and ozone treatments exerted antibacterial effect against S. mutans, whereas chlorhexidine and antibacterial dentin bonding application solely have the highest antibacterial effects. PMID- 29465051 TI - Resistance Pattern and Detection of Metallo-beta-lactamase Genes in Clinical Isolates of Pseudomonas aeruginosa in a Central Nigeria Tertiary Hospital. AB - Background: : Acquired metallo-beta-lactamases (MBLs) pose serious problem both in terms of treatment and infection control in the hospitals and report across the world showed an increase in their prevalence. However, there is a paucity of data from Africa, and their report is rare in Nigeria. Aim: : This study aimed to determine the prevalence of acquired MBL-resistant genes in carbapenem-resistant Pseudomonas aeruginosa in Abuja, North Central Nigeria. Materials and Methods: : Two hundred nonduplicate, consecutive isolates of P. aeruginosa from clinical samples submitted to the Medical Microbiology Laboratory of National Hospital, Abuja were screened for carbapenem resistance using imipenem and meropenem. Phenotypic detection of MBL-producing strains was determined using Total MBL confirm kits and E-test strips on isolates that were resistant to both Imipenem and meropenem. The MBL genes were detected using multiplex polymerase chain reaction, while the gene variant was determined by sequencing. Results: : Twenty two MBL-producing strains were detected phenotypically, but only 5 harbored the blaVIM-1 gene, giving a prevalence of 2.5%. These 5 strains were resistant to all the antipseudomonal antibiotics tested except Aztreonam and Colistin. Other common MBL-genes were not detected. Conclusion: : The prevalence of MBL-producing strains of P. aeruginosa which poses serious challenge for therapeutics and infection control is currently low in Abuja, North Central, Nigeria. Therefore, rational use of the carbapenems and other antipseudomonal antibiotics, regular surveillance and adequate infection control measures should be instituted to limit further spread. PMID- 29465052 TI - Nasotracheal Intubation in Children for Outpatient Dental Surgery: Is Fiberoptic Bronchoscopy Useful? AB - Background: The aim of our study was to compare the hemodynamic responses and adverse events associated with nasotracheal intubation (NTI) using a fiberoptic bronchoscope (FOB) and a direct laryngoscope (DLS) in children undergoing general anesthesia for outpatient dental surgery. Methods: Eighty children (aged 5-15 years) were scheduled to undergo outpatient dental surgery under general anesthesia and of these children those who required NTI were included. Results: NTI was significantly longer in the FOB group (P = 0.03). In both groups, systolic blood pressure (SBP) and heart rate (HR) significantly decreased after the induction of anesthesia when compared with the baseline values. SBP was significantly higher in both groups at intubation and 1 and 3 min after intubation when compared with postinduction. SBP significantly increased in the DLS group compared with the FOB group at intubation and 1 min after intubation. HR was significantly increased at intubation and 1 min after intubation in the DLS group compared with the FOB group. Nose bleeding after intubation was significantly more frequent in the DLS group (30%) than in the FOB group (7.5%) (P = 0.034). The incidence of sore throat 24 h after surgery was 20% (8/40) in the DLS group and 2.5% (1/40) in the FOB group (P = 0.014). Conclusions: There are fewer hemodynamic responses and adverse events in the FOB group than in the DLS group; therefore, FOB can be safely used for NTI in children undergoing outpatient dental surgery, and FOB may be more successful than DLS for NTI. PMID- 29465053 TI - Erythropoietic Response to Anaemia of Dialysis Naive Patients with Chronic Kidney Disease in Zaria, North-West Nigeria. AB - Introduction: Chronic kidney disease (CKD) is a global health problem with an increasing prevalence worldwide. Anemia is one of its consistent and severe hematological complications although its mechanism is not fully elucidated. The primary defect could manifest as serum erythropoietin (sEPO) deficiency or EPO resistance. We set out to determine the erythropoietic response to anemia of patients with CKD and its relationship with their iron status in a cross sectional descriptive study of 91 patients in various stages of CKD. Materials and Methods: Soluble transferrin receptor (sTfR), sEpo, and serum ferritin levels were determined using ELISA method (Diagnostic Automation Inc and WKEA med supplies corp.). Data generated were analyzed using Epi Info version 3.5.3 and level of statistical significance was set at <=0.05. Results: Participants comprised of 50 females (54.9%) and 41 (45.1%) males with an overall mean age of 47 +/- 15 years. The major causes of CKD were hypertension (HTN) (50.54%), diabetes mellitus (DM) (6.59%), and HTN + DM (19.78%). The mean hemoglobin (Hb) concentration of the participants was 10.97 +/- 2.28 g/dl; the red cell indices were within normal ranges except for Red cell distribution width-Coefficient of variation (%) which was elevated (16.29%). The mean serum ferritin, sTfR, and sEpo were 70.58 +/- 46.44 ng/ml (interquartile range [IQR] 82.00), 22.9 +/- 49.7 ng/ml (IQR 15.00), and 12.49 +/- 33.47 IU/L (IQR 6.00), respectively, with a high variance. Serum ferritin and sTfR are consistently low across the stages of CKD (range between 54.54 ng/ml and 88.64 ng/ml), but sEPO for stage 3 and 4 showed a 2-fold increase when compared to normal level at Hb 10.97 g/dl (29.54 IU/L and 38.83 IU/L, respectively). Correlation between sTfR and sEpo (r2 = 0.96, P = 0.001), while between sEpo and serum ferritin (r2 = 0.02, P = 0.185), and between Hb and stage of CKD undulating (r2 = 0.41, P = 0.001). Conclusion: In contrast to some existing literature, this study has demonstrated that EPO resistance and iron deficiency contributes to anemia in CKD and serum ferritin can be used to assess the iron level of dialysis naive CKD patients at every stage of the disease. PMID- 29465054 TI - Evaluation of the School Environment of Public and Private Schools in Enugu to Ensure Child Health Promotion. AB - Objectives: Poor maintenance of school environment can cause or worsen illnesses among schoolchildren. The objective of this study was to assess the healthfulness of school environments of primary schools in Enugu East, Nigeria, and to compare the difference if any between public and private schools. Study Design: This was a cross-sectional noninterventional study of the school environments in Enugu East, Nigeria. Methods: Multistage sampling method was used to select the sample population. The participating schools were inspected and their head teachers were interviewed using a questionnaire. Scores were awarded using the School Health Program Evaluation scale. Results: Thirty-three schools were studied. The most common source of water for most schools was well. Eleven schools dump refuse openly. Three public schools only had functional toilets. All public schools were adequately ventilated and lit. One private school had a foodservice area. Ten schools did not have a play field, while three public schools had soaps for handwashing. The mean scores for public and private schools were 33.00 and 37.86, respectively. Three schools only attained the minimum score of 57 of a maximum of 66. Conclusion: The environment of primary schools in Enugu east, Nigeria, is unhealthy and unfriendly and currently cannot promote and protect the health of the schoolchildren. PMID- 29465055 TI - Evaluation of the Effect of Platelet-Rich Fibrin on the Alveolar Osteitis Incidence and Periodontal Probing Depth after Extracting Partially Erupted Mandibular Third Molars Extraction. AB - Aims: To evaluate whether the alveolar osteitis (AO) incidence after extracting partially erupted third molars differs when platelet-rich fibrin (PRF) is administered in the alveolar socket and to assess the influence of PRF on postoperative pain levels and periodontal probing depth. Settings and Design: In this split-mouth randomized study, 50 patients (17 men/ 33 women; mean age, 23.96 years) with bilateral symmetric partially erupted mandibular third molars were enrolled. Material and Methods: PRF was randomly placed in one extraction socket, whereas the other socket was left empty. A verbal rating scale was used to evaluate postoperative pain levels. AO development was evaluated on the 7th postoperative day. At 3 months postoperatively, periodontal probing depth was measured on the distal surface of the second molars. Results: In total, 8% of patients in the PRF group and 18% of the patients in the control group were diagnosed with AO. None of the smokers in the PRF group and 37.5% smokers in the control group were diagnosed with AO. Mean postoperative pain levels were lower in the PRF group than in the control group at all time points. At 3 months postoperatively, periodontal probing depths were found to be <=3 mm in both groups. Conclusions: PRF significantly reduced the AO incidence among smokers and had a positive effect on postoperative pain levels but not on periodontal healing. PMID- 29465056 TI - Effects of Inferior Alveolar Nerve Neurosensory Deficits on Quality of Life. AB - Objective: The purpose of this study was to investigate the effect of temporary or persistent neurosensory disturbance of the inferior alveolar nerve (IAN) on the quality of life using Oral Health Impact Profile (OHIP-14) questionnaire. Methods: The patients with the neurosensory deficit of the IAN that was confirmed by subjective and objective neurosensory tests formed the study group. The patients who had dental or oral and maxillofacial surgery procedures in the same unit and did not present neurosensory deficit were matched with the study group according to their gender and age and were presented as the control group. Both groups filled OHIP-14 questionnaire. Results: This study included 200 patients (122 female and 78 male), aged between 18 and 75 years. Kolmogrov-Smirnov, Levene, Mann-Whitney U, and Kruskal Wallis tests were used for statistical analysis. In study group, the average OHIP-14 scores were higher in women than in men in physical pain and handicap subgroups. There were significant differences between study and control groups in functional limitation, psychological discomfort, psychological disability, and handicap subgroups. The OHIP-14 scores were higher in study group compared with the control group. Conclusion: It was concluded that the patients with the neurosensory deficit of the IAN have a poorer quality of life than those without neurosensory deficits. PMID- 29465057 TI - The Role of Diffusion-Weighted Magnetic Resonance Imaging in the Differential Diagnosis of Simple and Hydatid Cysts of the Liver. AB - Introduction: The present study indicates that simple and hydatid cysts in liver are a common health problem in Turkey. The aim of the study is to differentiate different types of hydatid cysts from simple cysts by using diffusion-weighted images. Materials and Methods: In total, 37 hydatid cysts and 36 simple cysts in the liver were diagnosed. We retrospectively reviewed the medical records of the patients who had both ultrasonography and magnetic resonance imaging. We measured apparent diffusion coefficient (ADC) values of all the cysts and then compared the findings. Results: There was no statistically meaningful difference between the ADC values of simple cysts and type 1 hydatid cysts. However, for the other types of hydatid cysts, it is possible to differentiate hydatid cysts from simple cysts using the ADC values. Conclusion: Although in our study we cannot differentiate between type I hydatid cysts and simple cysts in the liver, diffusion-weighted images are very useful to differentiate different types of hydatid cysts from simple cysts using the ADC values. PMID- 29465058 TI - Beneficial Therapeutic Effects of Sildenafil on Bone Healing in Animals Treated with Bisphosphonate. AB - Objectives: The purpose of the present study was to evaluate the effects of sildenafil on mandibular fracture healing in animals treated with zoledronic acid by using histologic, histomorphometric, immunohistochemical, and radiodensitometric methods. Materials and Methods: A total of 36 Sprague-Dawley rats (3 months old) were used. All animals were treated intraperitoneally with 0.1 mg/kg zoledronate three times per week, for a total of 8 weeks. Postoperatively, the animals were divided into two groups: zoledronate group (Z), which had no treatment applied (n = 18), and zoledronate + sildenafil (ZS), which were treated daily with 10 mg/kg sildenafil (n = 18). Each group was divided into two subgroups and the animals were sacrificed at the end of week 1 (Z1 and ZS1, n = 9) and week 4 (Z4 and ZS4, n = 9) after the operation. Histologic, histomorphometric, immunohistochemical analysis, and radiodensitometry were performed on the test subjects. Results: Sildenafil-treated groups showed a significant increase in fracture healing scores. This result was supported by the densitometric, histologic, histomorphometric, and immunohistochemical findings. Conclusions: Sildenafil may have positive effects on accelerating and improving fracture healing, and it may be used as a supporting factor in bone healing in patients treated with bisphosphonate (BP) to prevent negative effects of BP's. PMID- 29465059 TI - Efficiency of Lasers and a Desensitizer Agent on Dentin Hypersensitivity Treatment: A Clinical Study. AB - Aim: The aim of this clinical study was to determine and compare the efficiency of the glutaraldehyde-containing agent (GCA), Nd:YAG, Er,Cr:YSGG lasers, and the combination of them on the dentin hypersensitivity (DH) treatment. Subjects and Methods: This study was performed with the participation of 17 healthy adult patients having 100 teeth with DH; the patients were randomly divided into five groups according to the treatment protocol: (1) application of GCA on sensitive teeth, (2) Nd:YAG laser (1 W/cm2, 10 Hz) irradiation on sensitive teeth, (3) application of GCA on sensitive teeth and then Nd:YAG laser irradiation, (4) Er,Cr:YSGG laser (0.25 W/cm2, 20 Hz) irradiation on sensitive teeth, (5) application of GCA on sensitive teeth and then Er,Cr:YSGG laser irradiation. Sensitivity levels were assessed by the Yeaple probe on the buccal surfaces of the teeth at a force setting of 10 g. Measurements were performed for 30 min, after 7, 90, and 180 days of the therapy to assess the effects of desensitization. The evaluations were analyzed using the one-way analysis of variance and repeated measurement test (P < 0.05). Results: After sessions, DH was significantly reduced in all groups at each measurement point. The Er,Cr:YSGG laser with or without GCA application were the most effective ones in DH treatment (P < 0.05). Comparison of the treatment regimens demonstrated that the scores achieved with the Yeaple probe were not significantly higher for the Nd:YAG laser groups than the GCA alone group. Conclusions: This clinical study shows that the Er,Cr:YSGG laser have promising potential for the treatment of DH. PMID- 29465060 TI - Cyclic Fatigue Resistance of Novel Rotary Files Manufactured from Different Thermal Treated Nickel-Titanium Wires in Artificial Canals. AB - Aims: The aim of this in vitro study was to compare the static cyclic fatigue resistance of thermal treated rotary files with a conventional nickel-titanium (NiTi) rotary file. Subjects and Methods: Four groups of 60 rotary files with similar file dimensions, geometries, and motion were selected. Groups were set as HyFlex Group [controlled memory wire (CM-Wire)], ProfileVortex Group (M-Wire), Twisted File Group (R-Phase Wire), and OneShape Group (conventional NiTi wire)] and tested using a custom-made static cyclic fatigue testing apparatus. The fracture time and fragment length of the each file was also recorded. Statistical analysis was performed using one-way analysis of variance and Tukey's test at the 95% confidence level (P = 0.05). Results: The HyFlex group had a significantly higher mean cyclic fatigue resistance than the other three groups (P < 0.001). The OneShape groups had the least fatigue resistance. Conclusions: CM-Wire alloy represented the best performance in cyclic fatigue resistance, and NiTi alloy in R-Phase had the second highest fatigue resistance. CM and R-Phase manufacturing technology processed to the conventional NiTi alloy enhance the cyclic fatigue resistance of files that have similar design and size. M-wire alloy did not show any superiority in cyclic fatigue resistance when compared with conventional NiTi wire.

AB - Background and Objectives: The objective of this study was to evaluate potential morphological changes in the brain tissue of patients with severe obstructive sleep apnea syndrome (OSAS) in comparison with normal subjects by using T1 weighted magnetic resonance imaging (MRI) technique. Material and Methods: This study comprised subjects with severe OSAS with an apnea-hypopnea index (AHI) more than 30 and normal subjects with AHI less than 5 according to polysomnography findings. The study subjects were evaluated using Three Dimensional Magnetization Prepared Rapid Acquisition Gradient Echo sequence on T1-weighted MRI. FreeSurfer morphometric procedure was used as the automated segmentation method and in both cerebral and cerebellar hemsipheres and segmental volumes of brain were analyzed. Results: Of the 22 patients with severe OSAS, 19 were male, three were female and their ages ranged between 40 and 60 years (mean age 50.27 +/- 5.3 years). Of the 22 control subjects 19 were male, three were female and their ages ranged between 40 and 60 years (mean age 49.36 +/- 6.95 years). There were no statistically significant differences in terms of age and sex properties between the groups. There was a statistically significant difference in BMI between the OSAS patients and the control group. There were statistically significant differences in polysomnographic features (time elapsed below 90% SaO2 (min), Epworth Sleepiness Scale, AHI, mean minimum SaO2 (%), mean O2 desaturation (%), and arousal index values) between the OSAS patients and the control group. Conclusions: The findings of our study indicated that even if severe, no structural changes occur in the course of mild, moderate, and severe OSAS.

AB - Background and aim: This study aimed to examine the microleakage of class V cavities of primary molars prepared by either a conventional dental bur or Er:YAG laser and one of two different adhesive systems. Methods: A total of 50 tooth samples from primary molars were used in this study. They were randomly assigned into five experimental groups of 10 samples each, according to the cavity preparation technique and the type of adhesive system applied to the cavities. Following cavity preparation, etching, bonding, and filling steps, samples were dyed using basic fuchsine and were sectioned longitudinally in buccolingual direction. Percentages of dye penetration at gingival and occlusal margins were calculated for each group. Results: Overall, microleakage scores of gingival margins were significantly higher than those of occlusal margins (P < 0.001). The group that underwent laser preparation, laser etch, and self-etch bonding procedures had worse microleakage scores for gingival margins. However, all groups had similar occlusal scores (P > 0.05). Conclusion: Self-etch bonding systems and cavity preparation with Er:YAG laser may be an alternative to conventional restoration of primary molars with compomers. Further studies are warranted to fully elucidate the effect of laser-based etching techniques in cavities prepared by laser. PMID- 29465063 TI - Posterior Reversible Encephalopathy Syndrome in the Emergency Service. AB - Posterior reversible encephalopathy syndrome (PRES) is an entity characterized by headache, altered mental status, seizures, visual disturbances, and focal neurological signs. The most common etiologies of PRES are hypertension and renal failure, and the most frequent pathophysiology is hyperperfusion. PRES is generally symmetrical, often in the occipital and parietal lobes, and is typically characterized by vasogenic edema in the subcortical white matter. This study involves a 38-year-old female patient who had hypertension, used immunosuppressive drugs and was also found to have nephropathy. After 3 months of treatment for PRES, the patient's symptoms had declined.

The orientation of the condylar heads can behelpful for the etiological diagnosis.This case report describes a 56-year-old woman who suffered from a unilateral, progressively increasing, radiating pain which intensified with the movement of the mandible and includes information about the diagnosis, management, radiographic and three-dimensional model features and review of the literature. PMID- 29465065 TI - Use of ECDC PPS HAI&AU data to evaluate adherence to national guidelines for antimicrobial treatment of community--acquired pneumonia AB - INTRODUCTION Point prevalence surveys are widely described as a useful tool for evaluating antimicrobial policy and adherence to guidelines. OBJECTIVES We aimed to investigate if data from the European Centre for Disease Prevention and Control (ECDC) point prevalence survey of healthcare-associated infections and antimicrobial use (PPS HAI&AU) canbe used to evaluate adherence to national guidelines for the treatment of community-acquired pneumonia (CAP) and to analyze the quality of treatment regimens. PATIENTS AND METHODS Data for 72 698 patients were collected in Poland between the years 2012 and 2015 according to the ECDC Protocol v.4.2. CAP was an indication for antimicrobial treatment in 3608patients. Patients hospitalized longer than 48 hours were excluded. A total of 667 patients met the inclusion criteria, and 79 regimens were recorded and evaluated as concordant or discordant with the guidelines. Afterwards, 7 experts scored the regimens from 1 to 5. The averages were calculated, and the results below 3.0 were considered as not optimal and those of 3.0 or higher-as optimal. Coherence of the experts' scores was evaluated. RESULTS Of all patients, 153 (22.8%) were treated exactly according to the guidelines. Nineteen regimens (24.0%) were optimal but discordant with the guidelines; they were administered to 346 patients (51.9%). The remaining 50 regimens (63.3%) were evaluated as discordant and not optimal and were used in 169 patients(25.3%). The correlation results of the experts' scores were significant. CONCLUSIONS ECDC PPS HAI&AU data can be efficiently used to assess adherence to guidelines. Despite low adherence (22.8%), almost 75% of patients received optimal antimicrobial treatments. Actions promoting the guidelines and time-series studies analyzing improvement of adherence should be considered. PMID- 29465066 TI - Prognostic utility of the N terminal prohormone of brain natriuretic peptide and the modified Model for End Stage Liver Disease in patients with end stage heart failure. AB - INTRODUCTION The N terminal prohormone of brain natriuretic peptide (NT proBNP) is secreted by cardiomyocytes in response to increased wall stress resulting from pressure and volume overload. The modified Model for End Stage Liver Disease (modMELD) scale reflects the systemic effect of heart failure (HF), which includes end-organ congestion and subsequent hepatic and renal dysfunction. OBJECTIVES The aim of this study was to assess the prognostic accuracy of NT proBNP and the modMELD score, as well as to compare their usefulness in the risk stratification of patients with end-stage HF awaiting orthotopic heart transplantation (OHT). PATIENTS AND METHODS We retrospectively analyzed the data of 641 consecutive adult patients awaiting OHT between 2012 and 2016. Exclusion criteria included "urgent status", OHT, and removal from the waiting list. Clinical and laboratory data were obtained at the time of admission to the waiting list. The primary endpoint was all-cause mortality during a one-year follow up. RESULTS In the overall population of 370 patients, the median age was 54.0 (46.0-60.0) years, and 87.6% of the patients were male. During the follow-up period, the mortality rate was 27.6%. The areas under the curve (AUCs) were 0.619 (95% CI: 0.557-0.681) for NT proBNP and 0.870 (95% CI: 0.833-0.906) for modMELD. The difference between the AUC for modMELD and NT proBNP was 0.251 (95% CI: 0.179-0.322, P <0.0001). CONCLUSIONS The usefulness of NT proBNP in evaluating the prognosis of patients with end stage HF awaiting OHT is limited. The modMELD score is a better prognostic marker of waiting list mortality than the NT proBNP serum concentration. PMID- 29465067 TI - Preliminary Study of the Role F-Box Protein 32 (FBXO32) in Colorectal Neoplasms Through the Transforming Growth Factor beta (TGF-beta)/Smad4 Signalling Pathway. AB - BACKGROUND F-box protein 32 (FBXO32) (also known as atrogin-1), a member of the F box protein family, was recently shown to be a transforming growth factor beta (TGF-beta)/Smad4 target gene involved in regulating cell survival. It can be transcriptionally silenced by epigenetic mechanisms in some cancers, but its role in colorectal carcinoma (CRC) is unclear. We investigated the role of FBXO32 in CRC and determined its prognostic significance. MATERIAL AND METHODS We used real time quantitative PCR, Western blot, and immunohistochemistry to elucidate the role of FBXO32 in clinical specimens and primary CRC cell lines. Differences in patient survival were determined by the Kaplan-Meier method and log-rank test. RESULTS We found that the FBXO32 and SMAD4 levels were higher in normal tissues than in CRC tissues, but PAI-1 and VEGF levels showed the opposite pattern. The expressions of FBXO32 and SMAD4 were related to clinicopathological parameters in CRC. Kaplan-Meier analyses showed that the 5-year overall survival of the low FBXO32 expression group was significantly shorter than that of the high-FBXO32 expression group (p=0.010). CONCLUSIONS The fbxo32 gene is a novel tumor suppressor that inhibits CRC progression by inducing differentiation. Elevated expression of FBXO32 predicts longer survival in CRC patients.

AB - The aim of the study was to analyze the key trends of medical staff provision for maxillofacial surgery facilities. It is established that the provision of the population with maxillofacial surgeons staff has slightly decreased from 0.08 (year 2011) to 0.06 (year 2015). The amount of staff positions at this period has increased by 17.22%, the intensity of growth of employed positions has grown by 15.74%, which makes the understaffing rate equal to approximately 8-10%. The coefficient of part-time workers has also varied slightly from 1.4 in 2011 to 1.26 in 2015. Over 93% of maxillofacial surgeons work in hospitals. The qualification category was awarded to over 46.0% of specialists in this field, 97.6% of maxillofacial surgeons have a specialist certificate. The results indicate the need for a new project of personnel policy strategy for further training and professional growth of maxillofacial surgeons.

AB - The aim of the study was to evaluate the prevalence of dental diseases requiring prosthetic treatment among rural population of Omsk region. The study involved 1247 residents from 12 rural areas of the Omsk region at the age of 18 to 87 years. Partial absence of teeth was found in 69.4+/-1.30%, 7.5+/-0.75% had a complete absence of teeth on one jaw and 3.8+/-0.54% on both jaws. Malocclusion is present in 29.5+/-1.29% of rural residents, the pathology of dental hard tissues, clinical symptoms of TMJ dysfunction, increased dental abrasion were revealed in 63.8+/-1.36%, 12.0+/-0.92% and 8.7+/-0.80%, respectively. Thus the study showed high prevalence of dental pathology that require prosthetic dental rehabilitation in rural areas of the Omsk region. PMID- 29465070 TI - [Root canals dentinal wall structure after photodynamic exposure]. AB - The aim of the study was to assess root canal dentinal walls structure after photodynamic exposure with the use of 0.5% photoditazine. A root canal dentin of 46 single root intact teeth removed for orthodontic indications was examined by scanning electron microscope JEOL JSM-6510 (Japan). Microphotographs of the root canal wall were obtained in the orifice, central and apical parts under*2000 magnification. It was found that photoactivation of 0.5% gel photoditazine by a light source, laser or diode, with a wavelength of 635-660 nm and a power of 150 200 mW is an effective technique for removing the smear layer of the root canal wall, which facilitates the maximum opening of the dentinal tubules to a depth of 2-3 MUm. The best result (the maximum number of open dentinal tubules, the absence of a smear layer) is observed with 3 min photoditazine exposure and 2 min of laser exposure. The method can be proposed as an alternative supplement to the conventional root canals irrigation.

AB - The aim of the study was to compare the effectiveness of laser singlet phototherapy and traditional photodynamic therapy the treatment of periodontal diseases in an animal model. The experimental model involved 70 male rats Wistar in which periodontitis was modeled and treated: in group I (30 animals) a nanosecond laser device for medical use with a wavelength of 1270 nm was used for 7 sessions in a 400 ns pulse mode, an average radiation power of 2 W, and a radiation density of 200 J/cm2, group II (30 animals) received photodynamic therapy with the administration of a photosensitizer, followed by irradiation with a laser wavelength of 660 nm for 7 sessions 2 Wt average radiation power, group III (controls, 10 animals) - traditional drug therapy. Morphological studies were performed on 7, 14 and 21 day after treatment. On day 7th and 14th the study revealed In group I the presence of full blood vessels and diffuse expressed leukocyte infiltration with an admixture of macrophages, in group II - pronounced edema of the tissue and vasoconstriction. On day 21 the picture included in group I regenerated periodontal ligament with dilated full blood vessels on the border with the bone beams of the alveolar bone, in group II a moderately pronounced edema of the periodontal ligament with single dilated vessels, in controls significantly destroyed periodontal ligament substituted with granulation tissue and periodontal ligament. Thus, the treatment of periodontitis with the methods of singlet phototherapy leads to the development of reactive inflammation and significant vascularization of periodontal tissues which contributes to the rapid regeneration and stability of remission.

AB - The objective of the research was to elaborate experimental-theoretical and clinic-bacteriological rationale for the application of laser diagnostic for identification of main pathogens of purulent-inflammatory processes in maxillofacial area. For germs identification by giant Raman scattering effect SERS-substrate with nano silver metallic balls, reference strains (Ps. aeruginosa 27853 and S. aureus 25923) and clinical cultures of Staphylococcus, Bacillus and Escherichia coli were used. Using an example of purulent inflammation pathogens we considered that each of bacterial species is characterized by individual spectral lines of Raman scattering, which allows to identify them in short term (1-2 min). Moreover the proposed method is highly sensitive (105-106 CFU/ml). Creation of germs library and device portability makes use of laser diagnostic for express-indication purulent infections possible directly in clinical conditions. Thus, analytical capability, quick result, high sensitivity and peculiarity, economical effectiveness due to lack of necessity to use growth medium and to transport it to microbiological lab gives an opportunity to consider laser diagnostic as a perspective universal express-method of clinical microbiology.

AB - The aim of the study was to evaluate the resorbable vs nonresorbable fixation efficiency in bone grafting for unilateral cleft lip and palate (UCLP) patients. Thirty eight UCLP patients aged from 7 to 17 years (mean 11.5+/-3.1 years) were divided in two groups with different types of cortical graft fixation: group 1 ? titanium screws (22 patients), group 2 ? resorbable pins (16 patients). The Bergland and Chelsea scales were used to evaluate the outcomes 8 months after surgery. Additional authors' original scales were introduced: bone volume scale and pyriform rim restoration scale. The Bergland and Chelsea scales have shown good results in groups 1 and 2 in 91 and 81% of cases, satisfactory in 4.5 and 19% of cases, respectively. Upon the bone volume scale good results were achieved in groups 1 and 2 in 64 and in 75% of cases, satisfactory results - in 18 and 19% of cases, respectively. Upon the pyriform rim restoration scale good results achieved in 59 and 88% of cases, respectively. We also took into consideration the influence of age, diagnosis, post-op complications. No statistically significant difference between groups was found, with neither age nor diagnosis showing any influence. Only postsurgical complications and the stability of the orthodontic design seem to be important for good bone formation after alveolar bone grafting.

AB - It reports the results of primary basal blood flow in partially edentulous bone tissue with atrophy, as well as comparative evaluation of haemomicrocirculation level of the alveolar bone mucosa after bone augmentation via tunneling and conventional methods. The results of the initial state of microcirculation in the mucous membrane of the alveolar process in the partially edentulous area show a 45% decrease of blood flow (M), its intensity (s) by 60%. Microcirculatory shifts in blood flow levels indicators, its intensity, vasomotor activity are more evident when using the conventional method, where revascularization takes more than five months. When using the tunnel method, there is an improvement in haemodynamic mechanisms of tissue blood flow regulation. Microcirculation is restored 4 months after surgery.

AB - The study objective was to determinate variations of stato-dynamical functional markers of postural balance system in the process of malocclusion treatment. Twenty patients aged from 14 to 30 years with class II malocclusion were recruited for this prospective study. All patients underwent electromyography of mm. temporalis and mm. maseter in rest and at maximal jaws pressure. Postural balance was evaluated by stabilometry platform and body's regions relationship was assessed by computer optical topography. Orthodontic interventions included using occlusal splint, dental straps or 'TwinForce' device. There were two diagnostic sessions: before and after one month of orthodontic treatment. The majority of patients after anterior dislocation of mandible demonstrated significant increase in unilateral masticatory muscles activity (r<0.05) which correlated with iliac crest position. According to computerized topography data superior iliac crest position was registered in opposite side with regard to muscle hypertonia. According to stabilometry data forward translation of the mandible resulted in retroversion of total pressure point projection (r<0.05). Asymmetric muscle working in the process of occlusal adjustment may provoke postural imbalance in distal body regions. It dictates postural system condition monitoring during orthodontic treatment.

PMID- 29465084 TI - Protein kinase D1 regulates subcellular localisation and metastatic function of metastasis-associated protein 1. AB - BACKGROUND: Cancer progression and metastasis is profoundly influenced by protein kinase D1 (PKD1) and metastasis-associated protein 1 (MTA1) in addition to other pathways. However, the nature of regulatory relationship between the PKD1 and MTA1, and its resulting impact on cancer metastasis remains unknown. Here we present evidence to establish that PKD1 is an upstream regulatory kinase of MTA1. METHODS: Protein and mRNA expression of MTA1 in PKD1-overexpressing cells were determined using western blotting and reverse-transcription quantitative real time PCR. Immunoprecipitation and proximity ligation assay (PLA) were used to determine the interaction between PKD1 and MTA1. PKD1-mediated nucleo-cytoplasmic export and polyubiquitin-dependent proteosomal degradation was determined using immunostaining. The correlation between PKD1 and MTA1 was determined using intra tibial, subcutaneous xenograft, PTEN-knockout (PTEN-KO) and transgenic adenocarcinoma of mouse prostate (TRAMP) mouse models, as well as human cancer tissues. RESULTS: We found that MTA1 is a PKD1-interacting substrate, and that PKD1 phosphorylates MTA1, supports its nucleus-to-cytoplasmic redistribution and utilises its N-terminal and kinase domains to effectively inhibit the levels of MTA1 via polyubiquitin-dependent proteosomal degradation. PKD1-mediated downregulation of MTA1 was accompanied by a significant suppression of prostate cancer progression and metastasis in physiologically relevant spontaneous tumour models. Accordingly, progression of human prostate tumours to increased invasiveness was also accompanied by decreased and increased levels of PKD1 and MTA1, respectively. CONCLUSIONS: Overall, this study, for the first time, establishes that PKD1 is an upstream regulatory kinase of MTA1 status and its associated metastatic activity, and that the PKD1-MTA1 axis could be targeted for anti-cancer strategies.

This study aims to assess its control in Galicia. METHODS: Voluntary random telephone interviews resulted in 149 completed questionnaires. The variables are described by percentages or means and standard deviations. A bivariate analysis was undertaken using the Chi square test. RESULTS: Participants were mostly middle-age (mean=45.7, SD=9.8) males (68.5%) with 20.8 (SD=10.5) years of professional experience in middle-size urban (58.4%) laboratories, who identified a higher risk when receiving items from the clinic (80.6%). Most technicians (57.7%) have a written protocol. Many (55.0%), significantly older males, do not check for item disinfection. Most technicians use gloves (62.4%) particularly younger staff at larger laboratories. Fifty-five point seven percent had been vaccinated against hepatitis B. Only 22.0% of technicians reported receiving training in cross-contamination control. CONCLUSIONS: Identified cross-infection control practices are below standards, and lack of training and protocols are a matter for concern. PMID- 29465088 TI - [The problem of hidden HIV infection].

AB - Donation after circulatory death (Maastricht type III donation) or controlled cardiac death refers to the retrieval of organs for transplantation purposes following death confirmed using circulatory criteria after the withdrawal of life support. The persistent shortfall in organ availability has prompted the development of donation programs following circulatory death for lung transplantation. The combined thorax-abdomen extraction in these cases is carried out in only twelve centres in Spain, while the combined use of abdominal normothermic regional perfusion (NRP) is even more exceptional. The first case of pulmonary and abdominal extraction in a Maastricht type III donor in Navarre with this type of preservation techniques is a milestone and the success achieved shows that it is a feasible and safe procedure. PMID- 29465090 TI - [Level of knowledge of Quality Commitment Campaign and of "do not do" recommendations amongst general practitioners, pediatricians and nurses Primary Care]. AB - BACKGROUND: To evaluate if the Quality Commitment Campaign (QCC) was sufficiently known among primary care professionals (PC), and second, to evaluate the knowledge about certain recommendations of what should not be done in PC. METHODS: A observational study was conducted. General practitioners (GP), pediatricians (PED) and nursing (NUR) participated. A direct question was asked about whether QCC was known and a set of dichotomous questions based on the "do not do" recommendations to assess their knowledge. A sample size of 288 professionals from each group was the minimum required for a sampling error of 5%, 95% confidence level and p=0.75. The field study was conducted with the collaboration of health services and professional and scientific organizations. Data were described by frequencies and mean (standard deviation), and compared by means of ?2/Fisher or ANOVA and t-test. RESULTS: A total of 1,904 professionals (936 GP, 682 PED and 286 NUR) answered. The QCC initiative was known by 828 (43.5%) professionals: 524 (56.0%) GP, 234 (34.3%) PED and 70 (24.5%) NUR (p<0.001). All the questions were correctly answered by 652 (69.7%) GP, 631 (92.5%) PED and 116 (40.6%) NUR. Significantly more mistakes (p<0.001) were made by those who did not know the QCC, worked in the private sector or were not considered responsible for overuse. Despite not knowing the QCC, 60% GP and 90% PED answered all the questions of the test correctly. CONCLUSIONS: NUR and GP could benefit from a greater diffusion of the QCC. As could those working in the private sector and those who believe that professionals have little responsibility for unnecessary overuse. PMID- 29465091 TI - [Public participation in health. A review of reviews]. AB - BACKGROUND: This study aims to synthesize knowledge about the role of the public's participation in the definition, prioritization, rationalization, monitoring or control of policies, plans, governance, investment/disinvestment, and design of health services. METHODS: Review of review articles (narrative or systematic) about consumer participation indexed in PubMed until August 2016. RESULTS: Forty-two reviews were identified (eighteen systematic and twenty-four narrative). The extent of participation was provincial/regional or national. The issues addressed covered: What is public participation? What benefits are expected? Who participates in the representation of citizens? How and to what extent do citizens participate and with what outcomes? The impact of public participation has hardly been studied. CONCLUSIONS: There is moderate evidence in support of the argument that public participation legitimizes decisions of the Health Authorities, and improves outcomes of health policies. There is consensus on how participation techniques should be applied but there is a need to inquire more deeply into the level of impact of this participation.

METHODS: Descriptive, cross-sectional and multicentre study. Intentional sampling of physicians and nurses with more than four months professional practice from four hospitals, five PC centres and twenty-nine NH in Granada was carried out. An ad hoc questionnaire was developed to assess perception of professional practice in eight dimensions (structure and processes of care, physical, psychological, social, spiritual, cultural, ethical aspects and care for the dying), frequency of ethical dilemmas, and obstacles to optimum care. Scores of different settings were compared using the ANOVA test and post hoc analysis. RESULTS: A total of 378 professionals participated, 215 (56.9%) from hospitals, 97 (25.7%) from PC and 66 (17.5%) from NH. NH professionals were older and had more professional experience than those from PC and hospitals, and they also rated both the institution and their own professional practice significantly better (p<0.01) than other professionals with respect to the dimensions of structure and processes of care, physical, psychological, social, spiritual, cultural aspects and care for the dying. Psychological and ethical aspects were the worst valued in all settings, with no differences regarding ethical aspects. Fewer ethical dilemmas were identified by PC professionals, while NH professionals perceived greater obstacles to end-of-life care in relation to other settings. CONCLUSION: Primary care and hospitalization presented similar results on the perception of end-of life care, and lower results than those of nursing homes, although in these centres more ethical dilemmas and more obstacles were identified.

AB - Acute upper gastrointestinal bleed (AUGIB) is one of the most common medical emergencies in the UK, with roughly one presentation every 6 min. Despite advances in therapeutics and endoscopy provision, mortality following AUGIB over the last two decades has remained high, with over 9,000 deaths annually in the UK; consequently, several national bodies have published UK-relevant guidelines. Despite this, the 2015 UK National Confidential Enquiry into Patient Outcome and Death in AUGIB highlighted variations in practice, raised concerns regarding suboptimal patient care and released a series of recommendations. This review paper incorporates the latest available evidence and UK-relevant guidelines to summarise the optimal pre-endoscopic, endoscopic, and post-endoscopic approach to and management of non-variceal and variceal AUGIB that will be of practical value to both general physicians and gastroenterologists. PMID- 29465097 TI - Quantitative data analysis of perceived barriers and motivators to physical activity in stroke survivors. AB - BACKGROUND: Levels of physical activity after stroke are low, despite multiple health benefits. We explored stroke survivors' perceived barriers, motivators, self-efficacy and intention to physical activity. METHODS: Fifty independently mobile stroke survivors were recruited prior to hospital discharge. Participants rated nine possible motivators and four possible barriers based on the Mutrie Scale, as having 'no influence', 'some influence' or 'a major influence' on physical activity. Participants also rated their self-efficacy and intention to increasing walking. RESULTS: The most common motivator was 'physical activity is good for health' [34 (68%)]. The most common barrier was 'feeling too tired' [24 (48%)]. Intention and self-efficacy were high. Self-efficacy was graded as either 4 or 5 (highly confident) on a five-point scale by [34 (68%)] participants, while 42 (84%) 'strongly agreed' or 'agreed' that they intended to increase their walking. CONCLUSION: Participants felt capable of increasing physical activity but fatigue was often perceived as a barrier to physical activity. This needs to be considered when encouraging stroke survivors to be more active.

AB - We investigated the effects of reinforced audit and feedback on the medical record documentation (MRD) of 35 surgical residents at a tertiary university hospital. In three phases (pre-intervention, 3 and 9-month post-intervention), 525 medical records were assessed. An educational guideline assisting residents to record more accurate MRD was developed. The MRD rate in the pre-intervention and immediate post-intervention phases had changed significantly. The MRD rate in the pre-intervention and 9 months after cessation of intervention was not statistically significant. Reinforced audit and feedback had only a short term effect on MRD. To achieve long lasting change, we suggest residents' MRD behaviour must be integrated in their periodic clinical performance evaluation and reinforced through positive feedback including incentive mechanisms.

AB - Gadolinium-based contrast agents have greatly expanded the capability of magnetic resonance imaging and have been used extensively in neuroradiology over the past 30 years. When initially developed they were thought to be relatively harmless; it was later discovered they are associated with nephrogenic systemic fibrosis and should be used with caution in certain patient groups, especially those with renal failure. Lately it has been found that the use of these contrast agents may result in deposition of gadolinium in the brain even in patients with an intact blood-brain barrier. While this has not been shown to be associated with any clinical effects, a precautionary approach has been advised by the regulatory authorities. Here we review the development of the gadolinium contrast agents, their use and the advice related to this new information.

AB - Patients with intra-cerebral metastases often receive glucocorticoids, particularly in the presence of peri-lesional vasogenic cerebral oedema.

AB - Successive governments of the UK have strongly supported two policies: an NHS free at the point of delivery, and the encouragement of consumer choice. It was natural for governments to think that amalgamating the policies would increase patient satisfaction, improve efficiency and save money. There are many reasons why this has not been well-received by patients and doctors and has not saved money, but the underlying problem is that there is a conceptual misfit between healthcare as public policy and as individual responsibility. Patients in the NHS cannot become consumers and doctors cannot become suppliers of goods and services. PMID- 29465105 TI - Communicating with a human voice: developing a relational model of empathy. AB - The medical profession has adopted a cognitive model of empathy, or detached concern, in its professionalism and practice. As a consequence there is now an empathy gap which has been demonstrated by lapses in patient care in the UK. There may also be an empathy gap developing in medical students during their training. This paper argues for the adoption of a relational view of empathy which embraces emotional and moral dimensions of the concept, acknowledges the importance of the clinical context and prioritises the relationship between the doctor and patient. A relational model extends to encompass the patient's family and all members of the healthcare team. By exploring the process of empathising in clinical practice I develop a relational model that is more appropriate for modern patterns of patient care and medical education than detached concern. Adoption of a relational model of empathy in training and practice can help bridge the empathy gap. PMID- 29465106 TI - MRI brain white matter change: spectrum of change - how we can grade? AB - Magnetic resonance imaging has become a widely used clinical tool for the assessment of neurologic symptoms, as well as being increasingly used in neuroscience research. White matter hyperintensities are common findings on brain imaging and their discovery leads to questions about best management, especially when findings are incidental or not considered relevant to the patient's presentation. This review will discuss the varied causes of white matter hyperintensities, consider how best to distinguish between them radiologically, and when they might have potential clinical relevance. PMID- 29465107 TI - Sanatoria revisited: sunlight and health. AB - Since the 18th century tuberculosis has been a major cause of death throughout the world. It is a highly infectious disease that spreads by droplet infection and finding effective treatment to combat tuberculosis took a great deal of time. One of the first treatments to have some real success was a stay in a sanatorium. Sanatoria were homes that provided patients with good food and fresh air (and therefore sunlight). The first sanatorium to use sunlight therapy (heliotherapy) seriously was founded in Leysin, Switzerland, by Auguste Rollier. Patients built up their sun exposure gradually to prevent sunburn or skin damage. We suggest that heliotherapy was more successful in treating tuberculosis than was appreciated once chemotherapy became available. The birth of heliotherapy coincided with an increased appreciation of the association of sunlight and health among the general public. The secret of its success is the combined effects of sunlight on the skin inducing the production of nitric oxide and vitamin. Nitric oxide is not only a messenger in the cardiovascular system and responsible for relaxation of vascular muscle but is also involved in the innate immune system. Vitamin D is responsible for immune system functions and multiple studies have found an association between tuberculosis immunity and high vitamin D levels. Therefore, it is understandable that providing tuberculosis patients with sunlight may have boosted their immune system and aided them in the fight against tuberculosis. In view of the high level of resistance to all drug regimens in some patients, perhaps it is time to revive the use of sanatoria in the fight against tuberculosis.

The fallacy consists of over reliance on metrics, and may be summarised as: 'if it cannot be measured, it is not important'. This paper describes the McNamara fallacy as it applies to medicine and healthcare, taking as examples hospital mortality data, NHS targets and quality assurance. PMID- 29465109 TI - In Carthage ruins: the illness of Sir Winston Churchill at Carthage, December 1943. AB - This paper reviews Churchill's illness in Carthage in December 1943. It was characterised by fever that lasted 6 days, left lower lobe pneumonia and two episodes of atrial fibrillation. He was managed in a private villa by Lord Moran, his personal physician, with the assistance of two nurses and the expert advice of colleagues. Sulphadiazine and digitalis leaf were prescribed and Churchill recovered. It is remarkable that, despite the severity of his illness, he continued to direct the affairs of State from his bed. PMID- 29465110 TI - James Craufurd Gregory, 19th century Scottish physicians, and the link between occupation as a coal miner and lung disease. AB - By the mid-19th century about 200,000 miners were employed in a UK coal mining industry still growing with the advances of the Industrial Revolution. Coal miners were long known to suffer poor health but the link to inhaling dust in the mines had not been made. In 1813 George Pearson was the first to suggest that darkening of lungs seen in normal individuals as they aged was caused by inhaled soot from burning oil, candles and coal, which were the common domestic sources of heat and light. In 1831 Dr James Craufurd Gregory first described black pigmentation and disease in the lungs of a deceased coal miner and linked this to pulmonary accumulation of coal mine dust. Gregory hypothesised that the black material seen at autopsy in the collier's lungs was inhaled coal dust and this was confirmed by chemical analysis carried out by Professor Sir Robert Christison. Gregory suggested that coal dust was the cause of the disease and warned physicians in mining areas to be vigilant for the disease. This first description of what came to be known as 'coal worker's pneumoconiosis' sparked a remarkable intellectual effort by physicians in Scotland, culminating in a large body of published work that led to the first understandings of this disease and its link to coalblackened lungs. This paper sets out the history of the role of Scottish physicians in gaining this understanding of coal worker's pneumoconiosis. It describes Gregory's case and the lung - recently discovered in the pathology collection of the Surgeons' Hall Museums, Edinburgh, where it has lain unnoticed for over 180 years - on which Gregory based his landmark paper.

AB - Graphene oxide (GO) membranes have shown excellent selectivities in nanofiltration and pervaporation. However, the water transport mechanisms in the unique membrane laminar structure are still not well understood, especially in pervaporation which involves selective permeation and evaporation. Herein, water transport in GO membranes was tested under two different modes: pressure-driven permeation and pervaporation. The pure water flux was found to be 1-2 orders of magnitude higher in pervaporation due to the large capillary pressure induced by evaporation. The water flux in pervaporation was suggested to be limited by evaporation at room temperature but surface diffusion at high temperature. PMID- 29465113 TI - Quantum corral effects on competing orders and electronic states in chiral d + id or f-wave superconductors. AB - Self-consistent calculations are performed to characterize the quantum corral effects on the electronic states of chiral d + id or f-wave superconductors in this paper. A variety of spatial structures of competing orders are revealed in the presence of ferromagnetic nano-corrals, and superconducting islands are found to be absent in the case of small corrals while being seen for large corrals. Compared with the local suppression of superconductivity by a magnetic impurity inside the corral, surprisingly, an additional remarkable feature, i.e., obvious oscillations or enhancement of superconductivity around a non-magnetic impurity, is observed inside the magnetic corral. This is important in view of applications, especially in view of the demand for devices to locally produce strong superconductivity. Meanwhile, the charge density displays obvious modulations due to quantum confinement but in contrast, the spin density pattern exhibits its robustness against the corral effect. Furthermore, we explore the local density of states so as to be directly checked by experiments. We demonstrate that a magnetic corral can suppress the formation of quasi-particle bound states induced by an impurity inside the corral in the chiral d + id state while the f-wave case shows different behaviors. These results also propose a new route to make a distinction between the two competing pairing states in triangular-lattice superconductors. PMID- 29465114 TI - Water transport confined in graphene oxide channels through the rarefied effect. AB - Understanding the mechanism of water transport inside an interlayer between graphene-based plates has tremendous value for theoretical studies and industrial applications. The fluid flow confined in nano-scaled spaces experiences a slip velocity near the wall, which is significantly different to that of bulk water. Here we propose a model combining classic hydrodynamics with kinetic theory to depict the dependency of the slip effect on the oxide concentration of valley plates. The influence of oxidized graphene on water flow is a comprehensive result of a slipped boundary, and depends on both the diffuse reflection coefficient of the wall, and the shrunken effective passageway caused by the electrostatic interactions between the oxidized surface and the water molecules. The former effect enhances the water flow, which reduces with increasing oxide concentration, while the latter effect inhibits water flow. We examine the diffuse reflection coefficient and the shrunken effective passageway at different oxide concentrations of the GO sheets by molecular dynamics simulations, and we quantitively predict the flux relationship at various concentrations. This work provides a molecular insight into transport processes of confined water and a useful guideline for the design of perfect graphene-derived membranes for desalination. PMID- 29465115 TI - Enhanced photocatalytic properties of ZnO nanorods by electrostatic self-assembly with reduced graphene oxide. AB - A series of ZnO nanorod (NR)-reduced graphene oxide (rGO) nanocomposites (NCs) (i.e., ZnO-rGO NCs) with varying rGO loadings were fabricated by electrostatic self-assembly of positively charged ZnO NRs with negatively charged graphene oxide (GO), followed by the hydrothermal reduction of GO to rGO. When compared with bare ZnO NRs, ZnO-5% rGO exhibited significant photoactivity 6 times higher in the photodegradation of rhodamine B (RhB), and 2 times higher than ZnO-5% rGO(H) synthesized by hard integration of GO and ZnO NRs. In the same manner, ZnO 5% rGO exhibited a significant photoactivity 3 times higher in photodegrading phenol, which is 2 times higher than ZnO-5% rGO(H). Furthermore, the adsorption properties of ZnO-rGO NCs towards RhB and phenol were significantly different as a result of the opposite charges of the two pollutants in aqueous solution, which also led to the formation of different key free radicals during the degradation reaction. Based on various characterization techniques, it is concluded that the enhanced photoactivity and photostability of ZnO-5% rGO originated from the synergistic effects between ZnO NRs and rGO nanosheets including higher specific surface area, enhanced photogenerated carrier separation, and strengthened protection effects from intimate rGO coupling. However, these synergistic effects were weaker in ZnO-5% rGO(H) which reflects the key importance of surface charge modification in producing a well-contacted interface. PMID- 29465116 TI - Polyphenols-rich extract from Pleurotus eryngii with growth inhibitory of HCT116 colon cancer cells and anti-inflammatory function in RAW264.7 cells. AB - Edible mushrooms are rich sources of bioactive components. In this study, a polyphenol-rich extract, designated as PPEP, was isolated from an edible mushroom, Pleurotus eryngii. Using ultra high performance liquid chromatograph combined with triple time-of-flight mass spectrometry (UPLC-TOF/MS/MS), gallic acid monohydrate, 3-(3,4-dihydroxyphenyl)-propionic acid, methyl gallate, syringic acid, ellagic acid and catechin were identified in PPEP. This phenolic rich extract PPEP exhibited anti-inflammatory effect in lipopolysaccharide stimulated RAW264.7 macrophages by inhibiting the overproduction of pro inflammatory mediators including nitric oxide (NO) and reactive oxygen species (ROS). It was demonstrated that the anti-inflammatory effects of PPEP were associated with the inhibition of iNOS expression, suppression of p-IkappaB protein expression and inhibition of NF-kappaB and IkappaB mRNA expression. Next, the inhibitory effect of PPEP against human colon cancer cells was also determined. PPEP suppressed cell proliferation of human colon cancer HCT116 cells in a dose- and time-dependent fashion, while it showed no inhibitory effect on normal human colonic myofibroblasts CCD-18Co cells at the same tested concentrations (0-200 MUg mL-1). Moreover, PPEP induced cell cycle arrest and led to extensive cellular apoptosis in human colon cancer cells, which was associated with the downregulation of cell cycle-related signaling protein, e.g. cyclin B and cyclin E, and the upregulation of apoptosis-related signaling protein caspase 3 and cleaved caspase-3. Overall, our results provided a basis for using PPEP as a promising preventive agent against inflammatory disease and colon cancer. PMID- 29465117 TI - Gold(i) phosphine compounds as parasite attenuating agents for malaria vaccine and drug development. AB - Here, the anti-malarial activity of two gold(i) phosphine compounds auranofin and [Au(d2pype)2]Cl (where d2pype is 1,2-bis(di-2-pyridylphosphino)ethane), were examined to inform their use as potential drugs and malaria parasite-attenuating agents. In vitro, the gold compounds were active against Plasmodium falciparum and P. knowlesi as well as the rodent parasite P. chabaudi AS. Attenuation of the parasite was observed when mice were inoculated with P. chabaudi AS infected red blood cells treated in vitro with [Au(d2pype)2]Cl (1 or 2 MUM) or auranofin (2 MUM) for 2 or 3 h. Quantitative PCR data showed persistence of low levels of parasite DNA up to 8 days post inoculation. In some experiments, there was microscopically detectable parastiemia following inoculation which subsequently cleared. Following 1 or 3 doses of gold compound-treated parasitized red blood cells (pRBCs), protection was not observed when these mice were subsequently challenged with wild type P. chabaudi AS. In experiments where microscopically detectable parasites were observed following in vivo inoculation, mice were subsequently fully protected against a challenge infection with wildtype parasites. In an infect-and-treat rodent model, the gold compounds were unable to inhibit P. chabaudi AS growth in vivo when administered orally. Gold compounds act via the inhibition of antioxidant systems which are critical in the pathogen's survival from attack by the host oxidants. In vitro, they directly inhibit the parasite thioredoxin reductase, hence the observed suppressive activity. On the other hand, in vivo, the gold compounds may not be readily available for absorption and thus pharmacokinetic studies will be required to further examine drug bioavailability following administration. With structural differences in redox mechanisms of P. falciparum and the human host being identified, gold compounds can be better designed to more efficiently target and selectively inhibit the parasite. PMID- 29465118 TI - Electric field analyses on monolayer semiconductors: the example of InSe. AB - External electric fields can be used to manipulate the electronic properties of two-dimensional (2D) materials. 2D InSe semiconductors possess high electron mobility and wide band gap tunability. Therefore, they have been proposed for use in ultrathin electronic devices. Here, using first-principles calculations, we study the charge polarization, structure, electronic structure, and gas adsorption of an InSe monolayer under vertical electric fields. We find that both the structural evolution and charge polarization rely on the directions of the electric fields. The hole effective mass at the valance band maximum can be decreased by fields that offer a possible route to increase mobility. In contrast, the fields have little impact on the effective mass of electrons at the conduction band minimum. Therefore, high electron mobility in InSe is retained under the fields. Besides, electric fields could alter the absorption intensity for gas molecules. Therefore, gas sensors could be an expected application. More importantly, this work systematically points out some key steps for setting up electric-field calculations in the popular VASP code, such as the cancellation of the symmetrisation of the charge density, avoiding electrons spilling out into the vacuum under high fields. PMID- 29465119 TI - Chemical synthesis of culmorin metabolites and their biologic role in culmorin and acetyl-culmorin treated wheat cells. AB - The Fusarium metabolite culmorin (1) is receiving increased attention as an "emerging mycotoxin". It co-occurs with trichothecene mycotoxins and potentially influences their toxicity. Its ecological role and fate in plants is unknown. We synthesized sulfated and glucosylated culmorin conjugates as potential metabolites, which are expected to be formed in planta, and used them as reference compounds. An efficient procedure for the synthesis of culmorin sulfates was developed. Diastereo- and regioselective glucosylation of culmorin (1) was achieved by exploiting or preventing unexpected acyl transfer when using different glucosyl donors. The treatment of a wheat suspension culture with culmorin (1) revealed an in planta conversion of culmorin into culmorin-8 glucoside (6) and culmorin acetate, but no sulfates or culmorin-11-glucoside (7) was found. The treatment of wheat cells with the fungal metabolite 11 acetylculmorin (2) revealed its rapid deacetylation, but also showed the formation of 11-acetylculmorin-8-glucoside (8). These results show that plants are capable of extensively metabolizing culmorin. PMID- 29465120 TI - High-performance optical projection controllable ZnO nanorod arrays for microweighing sensors. AB - Optical microweighing sensors are an essential component of micro-force measurements in physical, chemical, and biological detection fields, although, their limited detection range (less than 15 degrees ) severely hinders their wide application. Such a limitation is mainly attributed to the essential restrictions of traditional light reflection and optical waveguide modes. Here, we report a high-performance optical microweighing sensor based on the synergistic effects of both a new optical projection mode and a ZnO nanorod array sensor. Ascribed to the unique configuration design of this sensing method, this optical microweighing sensor has a wide detection range (more than 80 degrees ) and a high sensitivity of 90 nA deg-1, which is much larger than that of conventional microcantilever-based optical microweighing sensors. Furthermore, the location of the UV light source can be adjusted within a few millimeters, meaning that the microweighing sensor does not need repetitive optical calibration. More importantly, for low height and small incident angles of the UV light source, we can obtain highly sensitive microweighing properties on account of the highly sensitive ZnO nanorod array-based UV sensor. Therefore, this kind of large detection range, non-contact, and non-destructive microweighing sensor has potential applications in air quality monitoring and chemical and biological detection. PMID- 29465125 TI - Mismatch in cation size causes rapid anion dynamics in solid electrolytes: the role of the Arrhenius pre-factor. AB - Crystalline ion conductors exhibiting fast ion dynamics are of utmost importance for the development of, e.g., sensors or rechargeable batteries. In some layer structured or nanostructured compounds fluorine ions participate in remarkably fast self-diffusion processes. As has been shown earlier, F ion dynamics in nanocrystalline, defect-rich BaF2 is much higher than that in the coarse-grained counterpart BaF2. The thermally metastable fluoride (Ba,Ca)F2, which can be prepared by joint high-energy ball milling of the binary fluorides, exhibits even better ion transport properties. While long-range ion dynamics has been studied recently, less information is known about local ion hopping processes to which 19F nuclear magnetic resonance (NMR) spin-lattice relaxation is sensitive. The present paper aims at understanding ion dynamics in metastable, nanocrystalline (Ba,Ca)F2 by correlating short-range ion hopping with long-range transport properties. Variable-temperature NMR line shapes clearly indicate fast and slow F spin reservoirs. Surprisingly, from an atomic-scale point of view increased ion dynamics at intermediate values of composition is reflected by increased absolute spin-lattice relaxation rates rather than by a distinct minimum in activation energy. Hence, the pre-factor of the underlying Arrhenius relation, which is determined by the number of mobile spins, the attempt frequency and entropy effects, is identified as the parameter that directly enhances short-range ion dynamics in metastable (Ba,Ca)F2. Concerted ion migration could also play an important role to explain the anomalies seen in NMR spin-lattice relaxation. PMID- 29465126 TI - Effects of a galacto-oligosaccharide-rich diet on fecal microbiota and metabolite profiles in mice. AB - Galacto-oligosaccharides (GOS) are prebiotics that positively affect the host's gut microbiota, which is important for the health of the host. Most previous studies focused on specific flora components (e.g. Bifidobacterium and Lactobacillus); very few have investigated the relationship between flora and metabolites. Here, we used 16S rRNA analysis and metabolomics to analyze the effect of GOS on microbiota and metabolites. Results show that the abundance of Ruminococcaceae and Oscillibacter decreased significantly in GOS-fed mice. Twenty one metabolites, including oleic acid, arachidic acid, and behenic acid, decreased significantly in the GOS-fed mice. Fatty acid synthesis and blood triglyceride content significantly decreased in the GOS-fed mice compared with those in the control mice, suggesting that GOS may improve lipid metabolism in mice. Additionally, after three weeks of a GOS-rich diet, the mouse microbiota was significantly enriched in Alloprevotella, Bacteroides, and Parasutterella. The blood glucose level of the GOS-fed group was significantly higher than that of the control group, whereas the abundance of Coprococcus and Odoribacter (butyrate-producing bacteria) was significantly decreased. The metabolism of butyrate, known to reduce plasma glucose levels, was significantly downregulated in the GOS-fed mice, an effect potentially detrimental to the glucose metabolism of the host. This dual-omics analysis provided important information on the changes in host-microbe-metabolite interactions resulting from GOS supplementation. Our results provide evidence that GOS may improve lipid metabolism, and that long-term GOS supplementation had a detrimental effect on the host's glucose metabolism, which could be important for optimizing methods of prebiotic supplementation and developing approaches to prevent diseases using prebiotic interventions.

PMID- 29465129 TI - The photolysis of alpha-hydroperoxycarbonyls. AB - In this work, we theoretically elucidated the mechanism and predicted the major products of the photolysis of alpha-hydroperoxycarbonyls, known to be products of the atmospheric oxidation of biogenic volatile organic compounds (BVOC) and components of secondary organic aerosol (SOA) in rural and remote areas. Using 2 hydroperoxypropanal OCHCH(OOH)CH3 as a model compound, we show that the likely major photolysis mechanism is a fast 1,5 H-shift in the initially excited singlet S1 state followed by spontaneous elimination of singlet oxygen to yield an enol HOCH[double bond, length as m-dash]CHCH3, while intersystem crossing (ISC) to the triplet T1 state and C-C scission into HCO + HOOCHCH3 followed by expulsion of a hydroxyl radical from the unstable HOOCHCH3 is another product channel. The direct S1 reaction was found to occur at such a high rate that the quantum yield in atmospheric conditions is expected to approach unity. In the atmosphere, the enol should generally react with OH radicals or tautomerize into the more stable carbonyl O[double bond, length as m-dash]CH-CH2CH3. Vinylalcohol is shown to be a major end product of the photolysis of hydroperoxyacetaldehyde, an isoprene oxidation product. Taking into account also the important enhancement of the absorption cross sections over those of the constituent monofunctional compounds as observed for the analogous beta-ketohydroperoxides, (F. Jorand et al., J. Photochem. Photobiol. A: Chem., 2000, 134, 119-125) the atmospheric photolysis rate of alpha-hydroperoxycarbonyls was estimated to be in the range of (1 to 5) * 10-4 s-1, generally faster than the rate of their OH reactions. PMID- 29465130 TI - Targeted VEGF-triggered release of an anti-cancer drug from aptamer functionalized metal-organic framework nanoparticles. AB - Amino-triphenyl dicarboxylate-bridged Zr4+ metal-organic framework nanoparticles (NMOFs), 100-130 nm, are modified with a nucleic acid complementary to the VEGF aptamer. The nucleic acid-functionalized NMOFs were loaded with the anti-cancer drug doxorubicin (or Rhodamine 6G as a drug model), and the loaded NMOFs were capped by hybridization with the VEGF aptamer that yielded VEGF-responsive duplex nucleic acid gates. In the presence of VEGF, a biomarker over-expressed in cancer cells, selective unlocking of the gates proceeds through the formation of VEGF/aptamer complexes, resulting in the release of the loads. In addition, the VEGF aptamer locking units were conjugated to the AS1411 aptamer sequence that binds to nucleolin receptors associated with cancer cells, resulting in the construction of cancer-cell targeted VEGF-responsive doxorubicin-loaded NMOFs. The different drug-loaded stimuli-responsive NMOFs reveal selective permeation into MDA-MB-231 breast cancer cells, compared to their incorporation into normal MCF-10A breast cells, with a two-fold enhanced incorporation into the MDA-MB-231 cells of the AS1411 aptamer-functionalized NMOFs. Cytotoxicity experiments revealed impressive selective apoptosis of the doxorubicin-loaded NMOFs towards the MDA-MB-231 cancer cells compared to the normal MCF-10A breast cells. A 55% and 70% MDA-MB-231 cell apoptosis was observed upon subjecting the cells to the VEGF aptamer and the VEGF aptamer/AS1411 aptamer conjugate-caged NMOFs, respectively, for a time-interval of three days, where only <10% apoptosis of the MCF-10A cells was observed under similar conditions. PMID- 29465131 TI - Hierarchically ZnIn2S4 nanosheet-constructed microwire arrays: template-free synthesis and excellent photocatalytic performances. AB - Hierarchically ZnIn2S4 nanosheet-constructed microwire arrays (NCMAs) on a zinc substrate have been synthesized for the first time through a one-step solvothermal method without using any template or surfactant. The as-synthesized ZnIn2S4 microwires are constructed by vertical nanosheets preferentially exposing (006) facets, which are about 1-5 MUm in diameters and larger than 10 MUm in average length. Experimental results demonstrate that the hierarchically ZnIn2S4 NCMAs are converted from intermediate components of single crystalline indium nanowires, which are generated along the direction of (101) planes by a displacement reaction between Zn and In3+ during the initial synthesis process. This conversion of indium nanowires to hierarchically ZnIn2S4 NCMAs has been explained by a novel corrosion-exchange-self-assembly mechanism, which might indicate a novel strategy for preparing other ternary sulphide nano-microwire arrays. The prepared ZnIn2S4 NCMAs are used as photocatalysts, demonstrating effective photocatalytic degradation activity for diverse organic pollutants including different dyes, tetracycline and 2,4,6-tribromophenol (2,4,6-TBP). This efficient photocatalytic activity is ascribed to the strong absorption of ZnIn2S4 NCMAs in a wide range from ultraviolet to visible light as well as the preferentially exposed (006) facets of ZnIn2S4 nanosheets. PMID- 29465145 TI - Immunisation Registries at regional level in Italy and the roadmap for a future Italian National Registry. AB - BACKGROUND: Immunization Information Systems, or Immunisation registries (IRs), are essential to monitor and evaluate the accessibility, quality and outcomes of immunisation programmes both at local and national level. STUDY DESIGN: We conducted a cross-sectional survey in order to investigate and map the level of IRs implementation obtained by the 21 Italian Regional Health Authorities. On this basis we defined a roadmap towards implementing an Italian National IR. METHODS: We designed an online questionnaire. Data were collected from July to September 2016 from all the 21 Regional Health Authorities in charge of infectious diseases control and immunization management. RESULTS: 18/21 Italian Regions have fully implemented an IR, out of them, 11 use the same software for all Local Health Units. Two Regions have partially implemented their IRs and one Region is not yet computerised. CONCLUSION: The decentralization of the Italian Health System is reflected also on the IRs characteristics and functionalities in terms of fragmented implementation of IRs and diversity in the software systems and data flows in place. Future efforts should not only aim not only to clarify the functionalities of Regional IRs, but should also aim to define how aggregation of data at national level can be optimised.

AB - The phenomenon of "vaccine hesitancy" has only been studied for a few years, and this attitude is becoming a serious threat that can frustrate the efforts of recent years that have led to the achievement of relevant scientific advances to human health. The paper analyzes the possible causes, the scope of the phenomenon and its consequences, trying to identify the most effective actions to resolve this trend. PMID- 29465147 TI - Research on mesophilic aerobic microorganisms and Enterobacteriaceae in cultivated and commercialized Agaricus bisporus. AB - BACKGROUND: Production and consumption of fresh mushrooms reached high levels in recent years but only a few data regarding microbiological quality of these products are available, although their potential microbial load is expected to be high. EU and Italian legislation have not set a limit on microbial counts in these products and label information is often unclear. This study investigates the microbial quality of samples of fresh cultivated mushrooms sold in Tuscany so that both food business operators and legislators can obtain data about potential microbial risk for consumers and debate about the opportunity of realizing an update on fresh mushrooms labels that should include information to protect consumers' health. STUDY DESIGN: This study reports the microbial load in samples of cultivated and commercialized Agaricus bisporus. Samples were obtained from different shops in Florence, chosen among those products whose labels did not indicate how the product should be consumed. METHODS: From March through May 2014, 20 couples of samples of A. bisporus were acquired in Florence. Microbiological analysis included the quantification of the microbial counts for mesophilic aerobic microorganisms and Enterobacteriaceae, as indicators of hygienic practices during cultivation and manufacturing. The analyses were carried out at two subsequent stages: one immediately (T0) and one at the end of the shelf life (T1), i.e. close to the expiry date stated on the label. RESULTS: The high microbial load observed exceeds the reference values set as acceptable for raw foods in Tuscany and is worse than the ones reported in other studies on this subject. The results are particularly alarming in light of the fact that A. bisporus is usually consumed raw and there is no mandatory specification on the label that informs consumers that the product must be cooked before being consumed. CONCLUSION: This research highlights the importance of adequate and complete information on fresh mushrooms labels, that should include information about the need for sanitization before the consumption, the appropriate storage temperature, and the maximum duration of shelf life. Data obtained could also be useful for food business operators to gather information about the microbial quality of fresh cultivated commercialized mushrooms in order to implement quality controls of the production process and storage conditions.

AB - BACKGROUND: Pseudomonas aeruginosa, being responsible of a broad variety of infections, is considered an important nosocomial pathogen. The emergence of multiple-drug resistance among strains of P. aeruginosa appeared as a further public health concern. Due to the considerable ability of multiple-drug resistant P. aeruginosa strains to transmit themselves in the environment, we aimed to investigate the association of class 1 integrons with the antibiotic resistance profile of P. aeruginosa strains isolated from hospital wastewaters. METHODS: In this cross-sectional study, a total of 100 P. aeruginosa isolates were obtained from raw wastewater samples from February 2010 to January 2011 in a Teaching Burn Hospital in Guilan province. All isolates were identified as P. aeruginosa using standard microbiological tests. Antibiotic susceptibility was investigated using the disk diffusion method according to Clinical and Laboratory Standards Institute recommendations. All isolates were assayed for the presence of the class 1 integrons gene by PCR. RESULTS: Overall, 30 (30%) P. aeruginosa isolates were positive for the presence of class 1 integrons. The highest antibiotic resistance rates in both integron-positive and -negative isolates belonged to cephalexin and cephazolin, with 100% resistance. Amikacin and ciprofloxacin with the lowest level of resistance (13.3%) were the effective antibiotics against integron-positive isolates. The rates of MDR isolates were significantly higher among integron-positive isolates with 43.3% compared to negative isolates with 22.9% (P < 0.05). CONCLUSION: The results highlight the importance of class 1 integrons in multiple antibiotic resistance among P. aeruginosa isolates. Moreover, the spread of hospital derived wastewaters in the environment can be regarded as the origin of significant reservoirs for antibiotic-resistant pathogens.

AB - BACKGROUND AND OBJECTIVES: People with diabetes and cardiovascular complications need to be educated about the self-management of the disease at the time of diagnosis and during the follow-up to best benefit from what they learn. Education is most effective when offered to small groups of patients led by a professional team. The aim of the study is the evaluation of diabetes and food education aimed at improving the self-awareness of the disease, the management and the quality of the lives of diabetic patients with a previous myocardial infarction. METHODS AND RESULTS: The sample group consisted of 20 subjects suffering from diabetes mellitus type 2 with a previous myocardial infarction. First, subjects were administered a test to assess the degree of knowledge of diabetes and quality of life; they also performed a walking test and a food interview. Anthropometric assessments and serum chemistry parameters were taken into consideration. Subsequently, they attended 7 lessons on nutrition, diabetes and cardiovascular complications; post intervention, the sample group demonstrated statistically significant improvement in the knowledge of the disease, in anthropometric measurements and walking test. CONCLUSION: Although we have not found an improvement of biochemical parameters, informing diabetic subjects of their health conditions and complications is essential in order to achieve patient empowerment and the compliance. PMID- 29465150 TI - Frailty screening and assessment tools: a review of characteristics and use in Public Health. AB - INTRODUCTION: Frailty screening and assessment are a fundamental issue in Public Health in order to plan prevention programs and services. METHODOLOGY: By a narrative review of the literature employing the International Narrative Systematic Assessment tool, the authors aims to develop an updated framework for the main procedures and measurement tools to assess frailty in older adults, paying attention to the use in the primary care setting. RESULTS: The study selected 10 reviews published between January 2010 and December 2016 that define some characteristics of the main tools used to measure the frailty. Within the selected reviews only one of the described tools met all the criteria (multidimensionality, quick and easy administration, accurate risk prediction of negative outcomes and high sensitivity and specificity) necessary for a screening tool. CONCLUSION: Accurate risk prediction of negative outcomes could be the appropriate and sufficient criteria to assess a tool aimed to detect frailty in the community-dwelling elderly population. A two-step process (a first short questionnaire to detect frailty and a second longer questionnaire to define the care demand at individual level) could represent the appropriate pathway for planning care services at community level. PMID- 29465151 TI - Pre-pregnancy body mass index, gestational weight gain and adverse birth outcomes: some evidence from Italy. AB - BACKGROUND: Overweight and obese women present an increased risk of poor maternal and child health outcomes. The aim of this paper is to analyze the joint effects of pre-pregnancy body mass index and inadequate gestational weight gain on birth weight and gestational age in an Italian sample of pregnant women. METHODS: Data were obtained from a sample of about 2,000 pregnant women at the University Teaching Hospital of Perugia University (Italy) in 2013. We used the revised classification proposed by Institute of Medicine to identify gestational weight gains considered as appropriate. Logistic regression models were used to estimate the adjusted odds-ratios of women belonging to any BMI class different from normal (used as the reference category) and of women who increased their weight by an amount smaller or greater than normal, controlling for a large set of observable confounders. RESULTS: Higher probability of low birth weight was associated with both obesity (OR = 1.9124, s.e. = 0.526) and less than normal weight gains (OR = 2.3614, s.e. = 0.388). The probability of fetal macrosomia was found to be positively associated with more than normal weight increases (OR = 2.6232, s.e. = 0.465). Pre-term deliveries were associated with less than normal gestational weight gains (OR 1.7338, s.e. = 0.320). CONCLUSION: Overweight and obesity represent a big issue for public health. In particular, weight management during pregnancy and pre-pregnancy could determine negative health outcomes in newborns. In our study we found that inadequate weight variations during pregnancy, according to the Classification of the Institute of Medicine, negatively influence health conditions at birth. Stronger initiatives, especially in terms of midwifery, nurse training and informative policies should be adopted by policy makers. PMID- 29465152 TI - Inter- and intra-interviewer reliability of Italian version of Pediatric Evaluation of Disability Inventory (I-PEDI). AB - BACKGROUND: Childhood disabilities determine a range of immediate and long-term economic costs that have important implications for the well-being of the child, the family and the society. The Pediatric Evaluation of Disability Inventory (PEDI) measures capability and performance in children aged between 6 months and 7.5 years. It contains three scales: Functional Skills Scales (FSS), Caregiver Assistance Scale (CAS) and Modifications Scale (MS). The present study evaluated the measurement properties of the Italian version of the PEDI (PEDI-I) in patients with spastic cerebral palsy (CP). STUDY DESIGN: Reliability study. METHODS: The original PEDI was translated - including a cross-cultural adaptation - into Italian. Internal consistency and test-retest reliability were evaluated. RESULTS: Fifty-eight children with CP were recruited. According to inter interviewer reproducibility, the FSS domain revealed intraclass correlation coefficient (ICC) values ranging between 0.94 and 1.00. CAS domain revealed ICC values ranging between 0.94 and 1.00. The SEM values ranged between 3.25 (SDD=8.98) for SF and 5.24 for SC (SDD=14.5). According to intra-interviewer reproducibility, the FSS domain revealed ICC values ranging between 0.99 and 1.00. CAS domain revealed ICC values ranging between 0.92 and 0.99. The SEM values ranged between 3.44 (SDD=9.5) for SF and 3.75 for SC (SDD=10.36). The inter-interviewer and intra-interviewer reproducibility results showed very high ICC values for both FFS and CAS domains. Cronbach's alpha ranged between 0.94 and 0.99, indicating excellent internal consistency within each domain of the PEDI-I. CONCLUSION: The inter-interviewer and intra-interviewer reproducibility results of PEDI-I showed very high ICC values for FFS and CAS domains. Therefore, we recommend its application to evaluate the effect of treatment in children with CP. PMID- 29465153 TI - Knowledge and Attitudes on Food Hygiene among Food Services Staff on Board Ships. AB - BACKGROUND: Ships have long been sites for outbreaks of infectious diseases, particularly gastrointestinal diseases. The ship environment has the potential to facilitate the spread of such diseases, infecting susceptible cohorts of embarked passengers and crew. Gastrointestinal disorders among seafarers are fairly common and usually represent the first or second cause of requests for medical assistance aboard ships in international waters. STUDY DESIGN: The purpose of this study was to evaluate food safety and the level of knowledge among food service personnel on board merchant ships, where food handlers could be a cause of health problems for all crew members. METHODS: An anonymous self-administered questionnaire containing specific questions about food hygiene and safety knowledge was administered. RESULTS: The overall score of correct answers for the food safety aspects tested was 51.77 (SD 3.87) out of 76 points, corresponding to 68.12% of questions answered correctly. Food workers who followed a training course showed higher mean knowledge score (p < 0.05) compared to not-trained workers. The most relevant significant differences (p < 0.05) were noticeable in the personal hygiene, cross-contamination, safe storage, and knowledge of foodborne pathogens sections. CONCLUSION: Food services staff on board cargo ships should be adequately trained and should understand basic and fundamental aspects of food hygiene, related pathologies and sanitation, as they are responsible for the health and wellbeing of many seafarers. PMID- 29465154 TI - Implications of modified food choices and food-related lifestyles following the economic crisis in the Marche Region of Italy. AB - BACKGROUND: The economic crisis in Italy has led to profound changes in resource management not only at the macro level but also for individual families, causing substantial changes in different habits of Italians. STUDY DESIGN: The purpose of this research was to conduct a study on changes in family eating habits potentially triggered by the economic crisis was conducted in an area of the Marche Region in central Italy. METHODS: The research was conducted in the period 2016 - 2017 by administering a specific and anonymous questionnaire. RESULTS: The interviewed people has reduced its food consumption. In particular, analyzing the results for the animal protein food group, there has been a reduction in purchase of beef, and an increase in that of pork. Overall fish consumption has decreased by 44%, with a decrease in the purchase of fresh fish, and an increase in that of canned fish products. Finally, consumers have reduced their purchases of fresh and canned legumes, fresh vegetables, and fresh fruit. CONCLUSION: The economic crisis seems to have changed the eating habits and food-related lifestyle choices of the subjects studied, especially in the urban area affected by the deeper economic depression. These changes are likely to have permanent social consequences, and deserve to be analyzed also in smaller territories in order to better understand the dynamics of individual choices and the social framework. PMID- 29465155 TI - Effects of physical activity on sclerostin concentrations. AB - : Osteoporosis is a serious medical and socioeconomic problem of the 21st century. Mechanical load is a key regulator which controls bone formation and remodelling, with participation of osteocytes. Sclerostin is produced and released by mature osteocytes into bone surface, where it inhibits the conveyance of osteoblast proliferation and differentiation activating signals from mesenchymal cells, thus suppressing new bone formation. The goal of the study was an evaluation of the effects of a 12-week physical training programme on the levels of bone turnover markers [Sclerostin, Osteocalcin (OC), C-terminal telopeptide of type I collagen (beta-CTX)] in blood serum of women with osteopenia. MATERIALS & METHODS: The study included 50 women of the Regional Menopause and Osteoporosis Centre of the WAM Teaching Hospital, at the age of 50 75 years with the diagnosis of osteopenia, obtained on the basis of hip and/or lumbar spine densitometry (T-score from -1.0 to -2.5 SD). During the initial 12 weeks (between point 1 and 2), the patients maintained their previous, normal level of physical activity. During subsequent 12 weeks (between point 2 and 3), a programme of exercise was implemented. The programme included the interval training on a bicycle ergometer, three times a week for 36 minutes. During the entire study duration, all the patients received a supplementation of calcium (500 mg) and vit. D3 (1800 IU) once daily. Serum levels of OC, alkaline phosphatase (ALP), beta-CTX and sclerostin were assayed at 3 time points. RESULTS: After the course of the exercise cycle, the OC concentration was increased, sclerostin levels decreased, while no statistical differences were observed in beta-CTX levels vs. the period of physical inactivity. No correlations were found between sclerostin level changes and osteocalcin level changes during the training time, because of too small groups. Neither statistically significant were the differences in alkaline phosphatase, calcium and phosphorus levels. CONCLUSIONS: The obtained results emphasise the role of physical training as an effective stimulation method of bone formation processes in women with osteopenia. Sclerostin can be a marker of physical activity. < /p > < p >. PMID- 29465156 TI - The impact of serum adropin and ischemia modified albumin levels based on BMI in PCOS. AB - INTRODUCTION: The aim of this study was to evaluate the effects of polycystic ovary syndrome (PCOS) and body mass index (BMI) on serum adropin and ischemia modified albumin (IMA) levels. MATERIALS AND METHODS: This prospective cross sectional study was performed with a total of 120 women [group1; non-PCOS = 60 (BMI < 25 = 30, BMI >=25 = 30) and group 2; PCOS = 60 (BMI < 25 = 30, BMI >=25 = 30)]. Blood samples were collected between the third and fifth days of the women's menstrual cycles after a night of fasting. RESULTS: There were no differences between the groups in relation to age, basal follicle stimulating hormone, estradiol, thyroid stimulating hormone, prolactin, high-density lipoprotein cholesterol, total testosterone, dehydroepiandrosterone sulfate levels, systolic and diastolic blood pressures. A significant difference was found in basal luteinizing hormone, fasting glucose, insulin, homeostatic model assessment of insulin resistance, total cholesterol, low-density lipoprotein cholesterol, triglycerides, free testosterone levels, waist-to-hip ratios and the Ferriman-Gallwey scores between the PCOS and non-PCOS patients in the lean and overweight groups (p < 0.05). The serum adropin levels in the lean PCOS group were lower than in the lean non-PCOS group (p < 0.05) and were lower in the overweight PCOS group than in the overweight non-PCOS group (p < 0.05). There was also a statistically significant difference in serum IMA levels in the PCOS group than in the non-PCOS group in both the lean and overweight groups (p < 0.05). CONCLUSIONS: Although serum adropin levels were significantly decreased in the PCOS group, IMA levels increased. Further studies are needed to determine the effects of adropin and IMA in women with PCOS and to use a new marker to monitorize treatment outcomes. < /p > < p >. PMID- 29465157 TI - Serum concentrations of adipokines in men with prostate cancer and benign prostate hyperplasia. AB - INTRODUCTION: Obesity and prostate cancer are related, but the causal relationship remains unknown. The aim of the study was to compare concentrations of leptin, adiponectin and chemerin in patients with prostate cancer and benign prostate hyperplasia and to examine associations of the adipokines with the grade of prostate cancer, interleukin-6 (IL-6), insulin resistance and anthropometric and metabolic variables. MATERIAL AND METHODS: The study group consisted of 140 men divided into two groups: I- prostate cancer (n=74) and II- with benign hyperplasia (n=66). Serum leptin, adiponectin, chemerin, IL-6 and metabolic profile were measured. Considering histological differentiation prostate cancer patients were divided into 3 subgroups: well differentiated (Gleason score <= 6), moderately differentiated subgroup (Gleason 7), and poorly differentiated (Gleason >=8). RESULTS: There were no differences between groups in BMI, waist circumference, HOMA-I, serum levels of total cholesterol, glucose, triglycerides, adiponectin, leptin and chemerin. However, the concentrations of PSA, leptin-to adiponectin ratio and IL-6 were significantly higher in cancer group compared with benign hyperplasia group. In the poorly differentiated cancer subgroup, subjects had higher PSA, leptin, chemerin, IL-6 and triglycerides concentrations. Overweight and obese men with prostate cancer were more likely to have moderately or poorly differentiated cancer than those with normal BMI. In the all men serum adiponectin was significantly correlated with HOMA-I, BMI, glucose, triglycerides, cHDL. There were significant correlations between leptin and BMI, HOMA-I, waist, glucose, triglycerides and cHDL. Among all the participants we observed associations between chemerin and waist as well as triglycerides. In prostate cancer patients chemerin correlated with IL-6 and leptin. We measured significant positive correlations between Gleason score and chemerin and leptin concentrations. There was a positive correlation between adiponectin and PSA levels in all men, as well as in cancer group. CONCLUSION: Leptin-to-adiponectin ratio and IL-6 were elevated in men with prostate cancer. Leptin, chemerin and IL 6 were associated with Gleason score. The relationships between leptin, chemerin and IL-6 were dependent on each other. Overweight and obese men had a higher Gleason score. PMID- 29465158 TI - Evaluation of adipokines in children with cystic fibrosis. AB - INTRODUCTION: Patients with CF present numerous pathological conditions such as malnutrition, depletion of fat-free mass, metabolic disturbances (abnormal glucose metabolism, increased insulin resistance, chronic energy deficit, local and chronic inflammation), which could affect or be associated with altered adipokines concentration Material and Methods: We aimed in this study to investigate the levels of selected adipokines such as resistin, apelin, adiponectin to demonstrate their application as possible markers of inflammation. RESULTS: Serum level of resistin was higher (p < 0.001) and adiponectin - lower (p=0.02) in CF children than in healthy children. There was no difference in serum apelin level between two examined groups. However, values of adiponectin/BMI and apelin/BMI ratios in CF did not differ significantly from controls. Higher values of resistin/BMI ratio in CF in comparison to controls were observed Serum resistin/adiponectin ratio was significantly higher in CF patients than in controls (p < 0.0001). Resistin/BMI ratio correlated negatively with FEV1 (R:-48,p < 0.043). Serum resistin/adiponectin ratio correlated negatively with FEV1/FVC (R:-49, p=0.04), Adipokines showed no correlation with BMI and BMI-SDS, glucose, total cholesterol, and LDL-, HDL-cholesterol, triglyceride serum levels. Spirometric parameters FEV1, FVC, VC correlated negatively with serum glucose levels (R: -0.55, p < 0.018; R: -0.65 p < 0.0025; R:-0.76, p < 0.0008 respectively). FEV1 and FVC correlated positively with BMI SDS (R:0.58, p < 0.01; R:0.5, p < 0.036, respectively). CONCLUSIONS: A significant increase in resistin concentration expressed also as resistin/BMI, and resistin/adiponectin ratios, observed in children with CF may suggests that this adipokine is involved in the inflammatory process underlying the disease and is related to worse spirometric parameters describing airways obstruction.

AB - Stepped velocity tests were conducted on juvenile largemouth bronze gudgeon Coreius guichenoti in a swim tunnel respirometer, and oxygen consumption increased with swimming speed to fatigue and then decreased during recovery. Serum levels of total protein, glucose and triglycerides initially decreased, increased at fatigue and then decreased during recovery. Levels stabilized after 120 min, corresponding to the time necessary to recover from fatigue. PMID- 29465160 TI - Pharmacokinetics of orbifloxacin in crucian carp (Carassius auratus) after intravenous and intramuscular administration. AB - The pharmacokinetics of orbifloxacin was studied after a single dose (7.5 mg/kg) of intravenous or intramuscular administration to crucian carp (Carassius auratus) reared in freshwater at 25 degrees C. Plasma samples were collected from six fish per sampling point. Orbifloxacin concentrations were determined by high performance liquid chromatography with a 0.02 MUg/ml limit of detection, then were subjected to noncompartmental analysis. After intravenous injection, initial concentration of 5.83 MUg/ml, apparent elimination rate constant (lambdaz ) of 0.039 hr-1 , apparent elimination half-life (T1/2lambdaz ) of 17.90 hr, systemic total body clearance (Cl) of 75.47 ml hr-1 kg-1 , volume of distribution (Vz) of 1,948.76 ml/kg, and volume of distribution at steady-state (Vss) of 1,863.97 ml/kg were determined, respectively. While after intramuscular administration, the lambdaz , T1/2lambdaz , mean absorption time (MAT), absorption half-life (T1/2ka ), and bioavailability were determined as 0.027 hr-1 , 25.69, 10.26, 7.11 hr, and 96.46%, respectively, while the peak concentration was observed as 3.11 +/- 0.06 MUg/ml at 2.0 hr. It was shown that orbifloxacin was completely but relatively slowly absorbed, extensively distributed, and slowly eliminated in crucian carp, and an orbifloxacin dosage of 10 mg/kg administered intravenously or intramuscularly would be expected to successfully treat crucian carp infected by strains with MIC values <=0.5 MUg/ml. PMID- 29465161 TI - Assessment of the pharmacological interactions between the nematodicidal fenbendazole and the flukicidal triclabendazole: In vitro studies with bovine liver microsomes and slices. AB - Parasitic diseases have a significant impact on livestock production. Nematodicidal drugs, such as fenbendazole (FBZ) or its oxidized metabolite oxfendazole (OFZ), can be used along with the trematodicidal triclabendazole (TCBZ), to broaden the spectrum of anthelmintic activity. However, co-exposure to these compounds could lead to drug-drug (D-D) interactions and eventually alter the clinical profile of each active principle. The aim of this study was to assess the presence of such interactions by means of two in vitro models, namely bovine liver microsomal fractions and bovine precision-cut liver slices (PCLSs). To this end, an in vitro assessment involving incubation of FBZ and TCBZ or a combination of FBZ and TCBZ was carried out. Results with microsomal fractions showed a 78.4% reduction (p = .002) in the rate of OFZ production upon co incubation, whereas the sulfoxide metabolite of TCBZ (TCBZSO) exhibited a decreasing tendency. With PCLS, OFZ accumulation in the incubation medium increased 1.8-fold upon co-incubation, whereas TCBZSO accumulation decreased by 28%. The accumulation of FBZ and OFZ in the liver tissue increased upon 2-hr co incubation, from 2.1 +/- 1.5 to 18.2 +/- 6.1 (p = .0009) and from 0.4 +/- 0.1 to 1.3 +/- 0.3 nmol (p = .0005), respectively. These results confirm the presence of D-D interactions between FBZ and TCBZ. Further studies are needed to determine the extent of involvement of drug-metabolizing enzymes and membrane transporters in interactions between compounds largely used in livestock production systems. PMID- 29465163 TI - The Long History of the Diverse Roles of Short ORFs: sPEPs in Fungi. AB - Since the completion of the genome sequence of the model eukaryote Saccharomyces cerevisiae, there have been significant advancements in the field of genome annotation, in no small part due to the availability of datasets that make large scale comparative analyses possible. As a result, since its completion there has been a significant change in annotated ORF size distribution in this first eukaryotic genome, especially in short ORFs (sORFs) predicted to encode polypeptides less than 150 amino acids in length. Due to their small size and the difficulties associated with their study, it is only relatively recently that these genomic features and the sORF-encoded peptides (sPEPs) they encode have become a focus of many researchers. Yet while this class of peptides may seem new and exciting, the study of this part of the proteome is nothing new in S. cerevisiae, a species where the biological importance of sPEPs has been elegantly illustrated over the past 30 years. Here the authors showcase a range of different sORFs found in S. cerevisiae and the diverse biological roles of their encoded sPEPs, and provide an insight into the sORFs found in other fungal species, particularly those pathogenic to humans.

AB - A palatal organ, possibly used for food sorting and processing, has previously been identified among the vomerine toothplates of the chimaeroid Chimaera monstrosa. In this study, the palatal organ was described in six additional species, confirming it is a widespread trait among holocephalans. It is proposed that this palatal structure, which appears to differ in shape according to each chimaeroid's degree of durophagy and is not homologous to the palatal structure described in teleosts, be hereby referred to as Vacchi's organ. PMID- 29465165 TI - Validation of the Mood and Feelings Questionnaire (MFQ) and Short Mood and Feelings Questionnaire (SMFQ) in New Zealand help-seeking adolescents. AB - OBJECTIVE: This study examines the reliability and validity of the Mood and Feelings Questionnaire (MFQ) and Short Mood and Feelings Questionnaire (SMFQ) for measuring depression in New Zealand help-seeking adolescents. METHOD: A sample of 183 adolescents completed the 33-item MFQ, which includes all 13 items on the SMFQ, at three time points during a trial of a computerized intervention for depression. RESULTS: Both the MFQ and SMFQ demonstrated good to excellent Cronbach's alphas, moderate to strong item-total score correlations, moderate to strong correlations with quality of life and anxiety measures, and strong correlations with the clinician-rated Children's Depression Rating Scale-Revised and the Reynolds Adolescent Depression Scale 2 at all time points, indicating good reliability and content, convergent, and concurrent validities, respectively. Favoring sensitivity over specificity, the optimal cut-off value for differentiating depressed from nondepressed cases for the MFQ was >=28 and for the SMFQ was >=12. Both instruments demonstrated satisfactory diagnostic accuracy and sensitivity to change. CONCLUSION: The MFQ and SMFQ are free and simple instruments that can be used to identify depression and measure symptom change in New Zealand help-seeking adolescents. PMID- 29465166 TI - Full percutaneous biventricular support with two Impella pumps: the Bi-Pella approach. AB - Extracorporeal membrane oxygenation is used for acute respiratory distress syndrome, refractory cardiogenic shock, and out-of-hospital cardiac arrest with uncertain neurological status, and, until recently, it was the only minimally invasive option to achieve biventricular support. However, extracorporeal membrane oxygenation increases left ventricular afterload and requires systemic anticoagulation, which is a major contraindication in the context of thrombolytic therapy following an ischaemic stroke. Conversely, the Impella heart pumps by design unload the ventricle and require minimal anticoagulation. We report the first case of mechanical circulatory supported with Impella CP on the left and Impella RP on the right (Abiomed Inc., Danvers, MA) for acute biventricular failure due to suspected acute myocarditis in the context of thrombolytic therapy for ischaemic stroke. PMID- 29465167 TI - Computer Simulations Reveal a Novel Blocking Mode of the hERG Ion Channel by the Antiarrhythmic Agent Clofilium. AB - The binding modes of many hERG ion channel blockers are well understood, but a notable exception is clofilium, a potent antiarrhythmic agent whose action relies on blocking the current mediated by hERG. From the previously hypothesized binding modes of clofilium to hERG, only two can explain most of the experimental results. In this study, computer simulations are performed in order to analyze the hypothesized binding modes and to identify the consensus one. This is accomplished by employing molecular dynamics (MD) simulations and interaction energy calculations. The results show an unexpected binding mode, in which the quaternary nitrogen is placed in the upper part of the inner cavity, interacting strongly with Ser624, while the chlorophenyl group is located in the lower part, in better agreement with previous experimental results. This novel binding position also explains the higher affinity of clofilium for the related hEag1 channel and was correlated with the possibility that potent hERG blockers interact in specific ways with the residues near the intracellular activation gate, offering a new explanation that could help predict the potency of other hERG-blocking compounds. PMID- 29465168 TI - A new species of Sturisoma (Loricariidae: Loricariinae) from the Madre de Dios River basin, Peru, with a key to all congeners and comments on the type series of Sturisoma rostratum. AB - A new species of the genus Sturisoma from the Madre de Dios River, upper Madeira, Peru, is described. The new species can be differentiated from its congeners by the following characteristics: dorsolateral stripe reaching to less than half, or only half length of caudal peduncle (v. absence of dorsolateral stripe or, if present, spanning more than half caudal-peduncle length); premaxillary teeth longer than dentary teeth (v. dentary teeth longer); sexually mature adult males having well-developed odontodes on the sides of the head and a broader snout (v. adult males lacking well-developed hypertrophied odontodes or, if present, rostrum is same width as females' or immature males'); by having the ventral portion of the rostrum conspicuously darker than ventral surface of the body (v. rostrum light, with same colour as ventral portion of body, except in Sturisoma barbatum); by lacking the lateral process of the sphenotic (v. lateral process of sphenotic well-developed, except in Sturisoma tenuirostre); a dark spot on the first three branched pectoral-fin rays (v. brown spot absent, except in S. barbatum); and the frontal bone contributing less than half of dorsal border of the orbital ridge (v. extensive participation of the frontal, except in Sturisoma guentheri). Furthermore, the new species has 18-20 plates in the median series, which differentiates it from Sturisoma rostratum (21-22), and Sturisoma monopelte (21); and 14-15 coalescent plates, which differentiates it from S. tenuirostre (16-17). It is further differentiated from Sturisoma brevirostre by presence of an enlarged rostrum (v. rostrum not enlarged). A discussion regarding status of the type series and geographic distribution of Sturisoma rostratum is offered, and an identification key for all Sturisoma species is presented. PMID- 29465169 TI - "Time is Brain:" A concept anaiysis. AB - Time is brain has been heard echoing in the world of acute stroke since the early nineties. At that time, the use of intravenous recombinant tissue plasminogen activator (rt-PA) revolutionized the approach to treating acute ischemic stroke. However, the use of rt-PA is strongly time dependant, with a narrow window of opportunity of only 4.5 hours. There is also convincing scientific evidence of a significant relationship between time to rt-PA treatment and patient outcomes. Similar to rt-PA in the '90s, time sensitive endovascular therapy has transformed the treatment of acute stroke. Hence, time is brain has been referred to as a battle cry, with these three words significantly influencing the multidisciplinary stroke teams who provide care to stroke victims. Despite agreement in the scientific literature that time is brain represents the essence of hyperacute stroke care, this concept has not been studied through the methodological approach of a concept analysisframework. Therefore, the purpose of this concept analysis was to explore the concept of time is brain within the context of acute stroke. Walker and Avants (2011) approach to concept analyses was used to gain insight into the provision of optimal acute stroke care in clinical nursing practice. PMID- 29465170 TI - The Importance of Preserving Tax-Preferred Status for Employer-Sponsored Health and Retirement Plans. AB - The future of employer-sponsored health and retirement plans may be at risk. For years, employers have struggled to maintain and pay for these plans despite the increasing compliance and financial burdens imposed by legislative and regulatory action. Now, as Congress begins to lay the foundation for comprehensive tax reform, the need to raise federal revenue may trump the continuation of the tax preferences for employer-provided health and retirement benefits. Recent actions illustrate that the drive for federal revenue may not be sufficiently tempered by the potential negative impact on employers and employees who must bear the brunt of these revenue-induced changes. This article considers the erosion of protections offered by the Employee Retirement Income Security Act (ERISA) and the importance of maintaining the tax treatment of employer-provided benefits.

AB - Despite its complexities, the health savings account (HSA) is a powerful and growing element of the U.S. financial landscape. In the future, employers will likely be expected to provide tax-advantaged savings programs for employees' current and future medical expenses. This article discusses investment lineup issues that must be addressed in order to optimize HSAs to help participants achieve successful outcomes. Plan sponsors at the forefront of addressing these issues (and perhaps others) will be in a better position to help their employees maximize both the health benefits and the wealth benefits provided for a secure retirement.

AB - While the United States continues to be the only developed nation without mandated paid maternity leave, U.S. employers are blazing their own trail for new parents. This article defines parental leave, explains what's driving the increased interest in paid parental leave among employers offering it and discusses how paid parental leave can benefit employers and employees alike. Finally, the author discusses why not all employers are offering these benefits as well as considerations for employers contemplating whether paid parental leave is right for them.

AB - Innovative approaches to managing an employee population with a high prevalence of type 2 diabetes mellitus can mitigate costs for employers by improving employees' health. This article describes such an approach at McCormick & Company, Inc., where participants had statistically significant improvements in weight, average plasma glucose concentration (also called glycated hemoglobin or A1c) and cholesterol. A simulation analysis applying the findings of the study population to Maryland employees with a baseline A1c of greater than 6.0% showed that participation in the program could improve glycemic control in these patients, reducing the A1 c by 0.24% on average, with associated cost savings for the employer.

AB - BACKGROUND: Death is a common occurrence in intensive care units (IC Us) and the complexity of care makes it difficult for nurses to find a balance between the patient's physical needs and the family's emotional needs, especially in circumstances of unexpected death. Cumulative or unresolved grief for families can have lasting negative repercussions. Nurses, therefore, need access to bereavement education in order to provide optimal- bereavement support. PURPOSE: The purpose of this review is to identify challenges and facilitators that nurses experience in delivering bereavement support during and after sudden or unexpected death in ICUs. METHODS: A narrative overview was conducted based on a literature search using GINA HL, Medline, Psyclnfo, Scopus, and Pro quest databases, as well as grey literature, revealing 241 articles, 15 of which met inclusion criteria. FINDINGS: Four themes surrounding bereavement support in the ICUs emerged: influence of hospital policies and organizational constraints; sign ~tl cance of time and trust; level of knowledge and support of staff and nurses' inner conflict, moral distress, and personal ways of coping. CONCLUSION: The availability of up-to-date literature in this area is limited. Further research could inform organizational poli- cies, nursing education, and nursing staff development to address existing barriers. With adequate resources, practical strate- gies could be implemented to provide bereavement support that ensures optimal bereavement outcomes for families experiencing sudden or unexpected death in ICUs.

AB - In early 2010, the Royal Alexandra Hospital (RAH) was the only tertiary hospital in Edmonton, Alberta, without a rapid response team (RRT). Once funding was obtained, the RAH RRT was developed with the mission of "Helping you make it happen" with the underlying philosophy that any call is a good call and the team is there to support care on the wards. The RAH RRT is unique, as it uses a registered nurse/respiratory therapist model rather than the physician model used by most tertiary centres. The RAH RRT provides consistent and efficient response to deteriorating patients and visitors to the hospital. The RRT does not replace the attending team, rather the team supports them to provide improved patient care and to escalate care if required. Other major centres in Alberta have heard about the success of the RAH model and are moving toward a similar model.

The barriers to achieving the mental health system we need are not just a chasm of a poorly organized system of care but a mountain range of issues that stop us from bringing mental health and well:being into the 21st century on a par with the rest of health care. This article reviews the progress that has been made, describes the continuing concerns and outlines a path forward toward holistic mental health and well-being in the workplace. We have been starting to move these mountains, but it is a heavy lift and will require unprecedented dialogue, engagement of diverse stakeholders and actions on many fronts to get us to the other side.

AB - Although the Mental Health Parity and Addiction Equity Act (MHPAEA) and associated regulations have been around for a while, behavioral health advocacy groups have expressed significant concern about a lack of enforcement to ensure compliance among health plans and employers. Federal and state governments have stepped up efforts to encourage MHPAEA compliance. This article presents recent developments in mental health parity, including a summary of the parity law requirements, new warning signs for nonquantitative treatment limitations, a confusing answer to a frequently asked question from the U.S. Department of Labor, an update on enforcement developments and the results of recent Milliman research on cost patterns since MHPAEA went into effect.

AB - Although the prevalence and destruction of opioid addiction have touched individuals and families across all social groups and geographies, until recently, federal and state-level efforts to confront this growing problem have lacked focus and rigor. With several legislative actions already underway and the recent enactment of the Comprehensive Addiction and Recovery Act (CARA), we will continue to see a focus on program development and treatment strategies. Employers can contribute toward curbing the opioid addiction epidemic in a number of ways and should play an instrumental role in facilitating increased awareness of and access to needed programming. These efforts will improve quality of life for employees and their dependents, as well as have a positive impact on productivity (including reduced absenteeism and decreased presenteeism). This article will explore the size and prevalence of the opioid epidemic, reflect on its implications for employers-including public policy initiatives-and suggest specific strategies for employer interventions. PMID- 29465185 TI - How Perceptions of Mental Illness Impact EAP Utilization. AB - Studies of employee assistance program (EAP) clinical use across multiple industries and multiple EAP delivery models range from highs greater than 5% to lows of less than 1 %. Despite the range in utilization, the rates of employee behaviors that indicate a behavioral health issue are significantly higher, suggesting far too little use of EAPs overall. Studies of the costs to an employer for an employee with a mental health issue are as high as 37% lost annual productivity. EAPs have attempted to raise utilization through a variety of efforts, with mixed results. Most EAP utilization initiatives fail to address the impact of stigma, misunderstandings about mental illness and the reluctance of many employees to seek counseling as an option for better management of stress, work-life balance and overall mental wellness. For both employers and EAPs, addressing the impact of stigma and perceptions of mental illness is costly, requiring greater direct employee engagement and education. However, it is a more effective means of increasing EAP use than current practices and, ultimately, can result in significantly higher net gains in productivity while reducing employers' direct costs.

PMID- 29465188 TI - Bringing Workforce Health to the Top Line-Expanding the Value Proposition for Workforce Health Improvement. AB - The pressure on employers to justify providing health benefits or to prove the value of health investment has never been greater. Many employers have resorted to cost shifting to employees to dampen the impact of health care costs on their companies or have avoided health investments, believing they don't deliver a return. Both strategies come with significant risk to employees, their dependents and the company's business performance. This article provides a framework for employers to better understand the full impact of workforce health and well-being on bottom-line costs and the opportunities for connecting workforce health and well-being to topline business performance metrics. Application of the principles presented in this commentary can help human resources/benefits personnel better understand the broader business impacts of their workforce health and well-being strategies as well as equip them to have a more meaningful role in workforce strategic planning.

PMID- 29465194 TI - Workplace Financial Wellness Programs Help Employees Manage Health Care Changes. AB - Employers and employees are navigating major changes in health insurance benefits, including the move to high-deductible health plans in conjunction with health savings accounts (HSAs). The HSA offers unique benefits that could prove instrumental in helping workers both navigate current health care expenses and build a nest egg for much larger health care costs in retirement. Yet employees often don't understand the HSA and how to best use it. How can employers help employees make wise benefits choices that work for their personal financial circumstances? PMID- 29465195 TI - Health Savings Accounts: An Emerging Cornerstone of the Health-Wealth Bridge?. AB - Several trends may help make health savings accounts (HSAs) a ubiquitous part of Americans' financial planning. When one looks at the totality of factors, it is easy to see how HSAs can become a vital connection be- tween active and retiree health care needs and between retirement income and retiree medical needs. However, it is also easy to see the clouds over the horizon that could stall HSA growth in coming years. This article discusses both.

Twelve years later, growth in HSA eligibility, participation, contributions and asset accumulations suggests we just might achieve that prediction. This article shares one plan sponsor's journey to help employees accumulate assets to fund medical costs-while employed and after retirement, It documents a 30-plus-year retiree health insurance transition from a defined benefit to a defined dollar structure and culminating in a full replacement defined contribution structure using HSA-qualifying high-deductible health plans (HDHPs) and then redeploying/repurposing the HSA to incorporate a savings incentive for retiree medical costs.

This is due to the ana- tomical prerequisites and the hemostatic system failure. Using of various research methods in practice can reduce the frequency of such complications. The purpose of the study is to identify predictors of high probability of epistaxis associated with the NTI and the pecu- liarities of the anatomical mucous membrane structure of the nasal passages, and to assess significance of blood coag- ulationfailures in these cases. MATERIALS AND METHODS: 45 patients (f-25 and m-20), aged 23 to 47 years, with physical status I-IIASA were analyzed. Depending on the degree of surgical trauma manipulation during intubation were formed three groups of patients in whom the NTI was atraumatic, moderately traumatic and overly traumatic. During preoperative period all patients underwent a rhinoscopy. Intubation trauma of the trachea was assessed by visual analogue scale. The results and discussion. The study of the nasal mucosa structure showed that with atraumatic intubation (Group 1; n=9) were dominated by deep type of bedding nonplethoric nonkinking vessels (66.7% ofpatients (n=6)). During mod- erate trauma intubation (Group 2; n=24), superficial and deep vessels were found equally (50% and 50%). In patients with severe trauma during intubation (Group 3; n=13), 100% of the patients, the vessels were located superficially, 75 % were convoluted, plethoric, mucosa contact bleeding. There were no anatomical changes. CONCLUSION: The source of bleeding are superficial, plethoric, kinking vessels of the mucous membrane. Hypocoagu- lation disorders, observed in patients during reconstructive surgeries, exacerbate such bleeding and can lead to fatal complications.

Blood pressure, heart rate, glucose and cortisol, and complications of airway management in children were analyzed. METHODS: The influence of the method of airway management with surgery in nose and sinuses in children in the stress response, hemodynamics, injuries of the airway were studied. The study included 140 patients aged 3 to 17 years. RESULTS: LMA FlexibleTMhas a minimal negative impact on the hemodynamics. Stress response is less pronounced when installing laryngeal mask than with tracheal intubation, which manifests itself in less cortisol concentration of 3.7%, 11.4% glucose. After removing the flexible reinforced laryngeal mask less than after extubation occurs: cough by 21%, 10% hoarseness, and sore throat by 26%. CONCLUSION: The use of the laryngeal mask airway during surgery in the nose and paranasal sinuses safer and less trau- matic manipulation compared with tracheal intubation.

THE PURPOSE OF THE STUDY: Comparison the efficacy ofvarious methods of maintaining the airway patency in the practice of reconstructive maxillofacial surgery. MATERIALS AND METHODS: 89 patients, who were divided into 4 groups, were examined. Group I (n=57) - classic laryngos- copy with the Macintosh blade, group II (n=14) -fiber-optic bronchoscopy (FBS) in clear consciousness. In group III (n=10) tracheal intubation was performed by the blade D-Blade of videolaryngoscope C-MAC (Karl Storz) or McGrath (Aircraft Medical Ltd.). In group IV (n=12) - retromolar endoscope (RAE) intubation by videostylet Shikani (Clarus Medical) and RME Bonfils (Karl Storz). At the time of laryngoscopy and tracheal intubation the duration of tracheal intubation (t), the maximum values of arterial blood pressure and heart rate, galvanic skin response (GSR) (NASTYA, Neyrok, Russia) were analyzed. The results and discussion. Unexpected difficult tracheal intubation occurredfor 31.6 % of the 1st group patients, need two attempts at laryngoscopy and tracheal intubation occurred in the subgroup 1B patients at 61.1 % (n=11), three at- tempts at 33.3 % (n=6), more than three attempts at 5.6% (n=1). FBS is the method of choice in patients with a planned difficult intubation, in cases of facial skeleton severe deformations . At the same time, local anesthesia and sedation is not capable ofproviding psycho-emotional comfort forpatients during FBS procedure. Visualization in 100% of the hy- popharynx structures at the McCormack I-II degree when using the blade D-Blade is appeared. The use of RME should not be recommended for routine planned and especially unexpected emergency difficult intubation. CONCLUSION: Comparison of methods of maintaining the airway allows to adjust the plan of sequential actions in difficult intubation, both planned and in an emergency situation. The effectiveness of blades type D-Blade is confirmed. In patients with facial skull deformity and impaired mouth opening (less than 1.3 cm) method of choice is awake intubation by fibrobronchoscope. The use if retromolar intubation is also justified, but this method may be accompanied by a lot number of failures.

METHODS: Randomized study included 23 scheduled patients operated upon due to cardiovascular diseases. Cardiac index (CI) was measured Comparative analyses of esCCO and others CO measurement methods used intraoperative was carried out. In the first group (n = 9) esCCO was compared with transpulmonary thermodilution (PiCCO-plus); in the second group (n = 8) - with pulmonary artery thermodilution; in the third group (n = 6) - with transoesophageal echocardiography (velocity time integral). RESULTS: In the 1st group direct correlation was found (r = 0,773, p <0.0001), but overestimation was found in 39% of cases; underestimation in 4%. The 2nd group showed direct correlation (r = 0.586, p <0.0001). The 3d group showed direct relationship (r = 0.68, p = 0.0018), but 66.7% of the measurements were out of reference interval (more than ? 15%). Blend- Altman method showed the dispersion of results in all groups. CONCLUSIONS: 1. Estimated continuous cardiac output measurement technique based on PWTT has a direct correla- tion with prepulmonary thermodilution and transoesophageal echocardiography, medium and high power respectively. 2. esCCO has significant differences with the referential techniques during general anesthesia in cardiac surgery pa- tients. 3. Calibration based on invasive blood pressure and outside cardiac output measurement does not increase the accuracy of measurements. 4. esCCO has a negative diagnostic value and cannot be recommendedfor the cardiac out- put evaluation during cardiac surgery. 5. This method can be useful for analyze general effectiveness of perioperative hemodynamics.

MATERIALS AND METHODS: 39 patients with hematological malignancies and ARF were enrolled in prospective study. The investigation of the patients included LUS, chest C, extravascular lung water index (EVLW) by transpulmonary ther- modilution, and bronchoalveolar lavage (BAL). RESULTS: There was correlation between the total number of B-lines and E VLW index (r = 0,40; p <0,05). The sensitivity, specificity of LUS in the total number of B-lines were 78% and 70%, respectively (and A UC 0,7). There were correla- tions between A-lines and volume of hyperaerated lung regions (r = 0,40; p <0,05) and normally ventilated (r = 0,60; p = 0,001) regions, between A-lines and the total lung volume (r = 0,50; p = 0,001), between A-lines and volume of poorlyventilated lung regions (r = -0,40; p = 0,001), A-lines and weight of normally ventilated lung regions (r = 0,50; p = 0,001), A-lines and weight of poorly ventilated regions (r = -0,35; p <0,05), total count of B-lines and volume of poorly ventilated lung regions (r = 0,4; p = 0,001), between total count of B-lines and weight poorly ventilated lung regions (r = 0,4; p = 0,001). There were associations between USfeathers and etiology ofpneumonia. A-lines were often detected in patients with gram-negative bacterial pneumonia and fungal pneumonia more than in patients with pneu- mocystis pneumonia. B-lines were detected often in patients with Pneumocystis pneumonia. Sensitivity ofLUS pleural effusion assessment was 95%, specificity was 90%. CONCLUSION: LUS is high sensitivity and specificity method to detect lung lesions in patients with ARF.

OBJECTIVES: define lung complication risks, evaluate the effect ofprotective lung ventilation (PLV) on lung functioning, and investigate the feasibility ofpreventive PB in higher pulmonary risk (PR) patients. MATERIALS AND METHODS: 66 patients participated in prospective randomized research. Allocation was based on PR and intraoperative mechanical ventilation type. PLV includedfollowing parameters: PCK PIP - up to 20 cm H20, Vt - 6 ml/ kg of PBW, PEEP - 5-10 cm H20, IE ratio - 1:1.5-1:1, EtCO2 - 35-42 mm Hg, FiO2 - 45-60%, lung ventilation during CPB, alveolar recruitment. Four groups were formed: A - higher PR plus PLV- B - higher PR plus conventional LV (CLV), C - lower PR plus PLV- D - lower PR plus CLV PIP PEEP dynamic compliance, p/f ratio and intrapulmonary shunt (Qs/Qt) were recorded. Seventeen patients of group A underwent PB. RESULTS: Advanced dynamic compliance, higher p/f ratio and lower Qs/Qt were seen in group A, in comparison with group B (p< 0.05). Lower Qs/Qt was seen in group C, in comparison with group D (p<0.05). Mucus obstruction of subsegmental bronchi was observed in 53.3% of higher PR patients. More than half ofpatients without PB sufferedfrom postoperative lung complications (70.4 vs. 34.2 7%, p328.5 ng/l, PCT>1 ng/ml), but presepsin have a statistically significant lower specificity in comparison with procalcitonin (31% and 61%, respectively). This fact limits the use of presepsin in routine practice in multidisciplinary surgical hospital. Quantitative determination ofprocalcitonin is most preferably for the detection of septic complications in patients in the postoperative period, the results ofpresepsin must be interpreted only with other biochemical and hematological parameters. PMID- 29465205 TI - [PARTICIPATION OF AROMATIC MICROBIAL METABOLITES IN THE DEVELOPMENT OF SEVERE INFECTION AND SEPSIS.] AB - : Background Actuality of the problem of infection in critically ill patients remains high. Addition a local infectious processes have a tendency to rapid generalization and sepsis. Neutrophilsfunction failure plays a key role in the patho- genesis of infectious complications and sepsis. The hypothesis about the role of microbial metabolites in the formation of immunosuppression, in particular in the inhibition of phagocytic activity of neutrophils as the first line of defense against bacteria is acquiring more and more supporters. Among the microbial metabolites aromatic compounds, such as phenylcarbinol acid (PCA) are of particular interest. Their concentration in the blood reaches a maximum in case of generalized infection, and correlates with mortality in patients in critical conditions, and PCA biological activity confirmed by earlier researches in vitro. The purpose of the study was to reveal the relationship of the PCA with the severity of bacterial infections and to assess the effect of PCA on neutrophils phagocytic activity. MATERIALS AND METHODS: At the first stage the levels of PCA (GCh-FID method) in the serum ofpatients (n=57) with a documented bacterial infection of varying severity, confirmed APACHE II and SOFA scales were analyzed comparing with healthy donors (n=72). During the second stage the effect of clinically-relevant concentrations of PCA on neutrophils phagocytic activity ofperipheral blood was analyzed in vitro. RESULTS: The levels ofphenylacetic (PAA), phenyllactic (PLA), hydroxyphenylacetic (p-HPAA) and hydroxyphenyllactic (p-HPLA) acids in patients were significantly higher than in healthy donors, reaching the highest values in severe infection. High direct correlation of PCA levels with the indicators ofscales APACHE II and SOFA was detected. A significant decrease in the number ofphagocytic neutrophils under the influence PAA, p-HPAA and PLA was identified in vitro experiment on average 11%. The most significant influence p-HPAA, PLA and p-HPLA have made on the intensity of the neutrophils absorption capacity reducing this parameter by an average of 26%. Also noted that phenylpropionic acid (PPC) which is in blood of healthy donors, disappears in critical ill patients. CONCLUSION: Phenolcarbonic acids level in the blood serum shows the severity of bacterial inflammatory process. Ex- periment in vitro shows that the PCA in clinically-relevant concentrations is able to suppress the neutrophilsphagocytic activity.

SUBJECTS AND METHODS: 70 patients underwent determination of blood pressure, heart rate, SpO , the content of leu- kocytes, albumin, C-reactive protein, fibrinogen and TNF-a in arterial (femoral artery) and venous (subclavian vein) blood. Automatic biochemical analyzer Cobas-Integra 400 ('Roche", Switzerland), the test system Microlab STAR ELISA kit reagents "alpha TNF - ELISA - best" were used during the research. System statistical analysis included paired comparison of patients with favorable (n=27) and lethal (n=43) outcome, correlation, cluster; discriminating analysis, multidimensional scaling and plotting ROC curves with sensitivity and specificity indicators predictive value. RESULTS: Identfied predictors of outcome inpatients,from which to form a predictive model of CRP fibrinogen, albumin, and TNF-a arterial blood. It is established that if the basic treatment of the patient CRP <9,8 g/l,fibrinogen >3,43 g/l, albumin <28,9 gl and TNF-a <499,3 ng/ml, the probability of death was statistically significantly higher thanfavorable. CONCLUSION: It is assumed that therapeutic measures should be aimed at correction of the above mentioned indicators.

Group K (n=20) underwent general anaesthesia and postoperative analgesia on-demand. Group PMA+SA (n=23) got subarachnoid block and preventive multimodal analgesia (PMA) including ketoprofen, paracetamol and nalbuphine. At PMA group (n=21) general anaesthesia and PMA were used; at PMA+I (n=21) also bupivacaine wound infiltration was administrated; at PlvL4+S (n=20) - depo-corticosteroid was applied locally on affected spinal nerve root; at PMA+IS (n=24) wound infiltration and local corticosteroids were combined. Patients could use i.v. nalbuphine on-demand by PCA device in addition to PMA post-operatively. 7 days post-operatively, the pain scores using 10 cm VAS at rest and during movement were also recorded. RESULTS: Group K patients had not adequate pain relief during 4 postoperative days. At PMA group the postoperative analgesia was adequate during the whole assessment time, PMA group patients had significant less pain scores than at K group during 4 postoperative days. Patients at PM +SA had better than PMA group pain relief only during 2 hours postoperatively. Groups PMA+I and PMA+IS did not demand nalbuphine at al. Their pain scores were signifcant less than at PMA group during 2 postoperative days. CONCLUSIONS: Postoperative analgesia on-demand is not adequate but the PMA is. Subarachnoid block results in decreasing severity of pain only during first hours postoperatively. The additional bupivacaine wound infiltration in pa- tients with lumbar herniated disc follows avoiding of opioids and significant pain relief during 2 postoperative days.

The purpose of the review is a synthesis of literature data about the influence of genetic factors on pain perception and its treatment. The review included information obtained from SCOPUS, MedLine, EMBASE. The search keywords were: pain, pharmacogenetics, polymorphism, analgesics.Describe the effect ofgene polymorphisms of OPRM, 5HTRIA, 5HTR2A, COMT GCHI, SCN9A, KCNSI, CACNA2D3, CACNG2, PTGSI, PTGS2, MDRJ/ABCB] on the perception of pain, and CYP2D6, CYP2C9, CYP3A4 on the pharmacokinetics and pharmacodynamics of medi- cations used in the treatment of pain.

OBJECTIVE: To reduce the number of ophthalmic complications of general anesthesia by prophylactic use of new mito- chondria-targeted antioxidants - Vizomitin (eye drops). MATERIALS AND METHODS: 70 patients, which was supposed to perform the average duration of operations under general anesthesia were randomized into 3 groups depending on the method specific (pharmacological) prevention of corneal erosions: (1) control (specic (pharmacological) prevention was not carried out), (2), using preparation "natural tear, and (3) "Vizomitin" preparation. Postoperative biomicroscopy was performed to assess the condition of the cornea, tear film stability was measured and the height of the tear meniscus. RESULTS: When using eye drops "Vizomitin" value is an indicator of stability of the tear film on the 3rd day after the operation more than in the control group of patients by 51% (p = 0.012) and patients groups, natural tear by 57% (p = 0.013). Surgical interventions performed under general anesthesia, leading to an increase in the number ofpatients with decreased tear meniscus height index of the control group with 4 to 7 patients (p = 0.30) in the group of natural tear from 3 to 11 patients (p = 0.008) . In the group with drug "Vizomitin" the number of such patients is reduced from 7 to 1 (p = 0.018). CONCLUSION: In the surgical procedures under general anesthesia eye drops "Vizomitin" effectively prevents the devel- opment of corneal erosion.

One of the rare complications of epidural anesthesia is pneumocephalia. The article describes a case of pneumocephalia after epidural anesthesia performed for anesthetic management of the hip replacement surgery. Eight hours after the epidural anesthesia the patient had depression of consciousness progressing to coma. Computed tomog- raphy of the brain detected pneumocephalia. Symptomatic treatment provided a regression of neurological deficit. CT scanning of the brain on the 8th postoperative day showed resolution ofpneumocephalia. The patient was discharged from the hospital on the 15th day after surgery. The most probable mechanism explaining this case ofpneumocephalia development is the theory ofa the inverted bottle).

The treatment of 48 patients was analyzed. Immediately prior to surgery, at random, patients were divided into primary (n = 26) and control group (n = 22). In the study group for compensation the energy deficient states and organ hypoxia in the pancreas and the liver during the intra- and postoperative periods remaxol was included in the infusion therapy, the introduction ofwhich had been began before the start of anesthesia. In the control group antihypoxants weren't used. Integral assessment of prognosis and severity on a scale SAPS II and APACHE II. Status of energy and the type of energy deficit was estimated by the transport of oxygen and the concentration of lactate. In order to determine the level of stress exposure and the for- mation of adaptive reactions examined quantitative and qualitative composition of the peripheral blood. The study was conducted prior to surgery, on the 2nd and 5th day perioperative period. Inclusion in the scheme of metabolic remaxol program in the perioperative period in patients with malignant diseases of hepatopancreatoduodenal zone promotes the reduction of different types ofgipoergosis, efficient delivery and oxygen consumption, the adequacy of tissue oxygenation and restoration of adaptive physiological reactions such as.

AB - : Since the 1980s, the emergency nurse practitioner (ENP) role has evolved as increasing socioeconomic pressures and changing government policy have led to new working practices in emergency departments. Similarly, a lack of consensus regarding educational support for ENPs and the regulation of ENP training, mean that variations remain in the scope of practice, role description and academic requirements for ENPs. AIM: To explore ENPs' perceptions of their changing role, including their educational requirements and whether their training needs are being met. METHOD: This qualitative phenomenological study examined the views of six ENPs using semi-structured interviews. FINDINGS: The study identified four themes: inadequate protected time for continuing professional development (CPD); importance of senior medical support in role expansion and CPD; inconsistent educational preparation for expanded roles; and the ENPs' perceived reasons for role expansion. Although all the participants stated that it was challenging to find time for CPD when working in busy clinical environments, this was regarded as less important than the positive effect of senior medical support for advanced roles. CONCLUSION: Over the past three decades, the ENP role has become well established, which has led to increased confidence, and the development of collaborative ways of working, among ENPs and their colleagues. However, while ENPs have embraced the challenges of their changing role, educational support has not been consistent. There are still disparities in ENPs' scope of practice, expectations of the role between services, and the educational preparation required to undertake the role.

AB - Patients exhibiting challenging behaviour, which includes any non-verbal, verbal or physical behaviour, is a significant issue in healthcare settings. Preventing such behaviour and the harm it can cause is important for healthcare organisations and individuals, and involves following a public health model comprised of three tiers: primary, secondary and tertiary prevention. Primary prevention aims to reduce the risk of challenging behaviour occurring in the first instance; secondary prevention involves reducing the risk associated with imminent challenging behaviour and its potential escalation; and tertiary prevention focuses on minimising the physical and emotional harm caused by challenging behaviours, during and after an event. De-escalation should be the first-line response to challenging behaviour, and healthcare staff should use a range of techniques - maintaining safety, self-regulation, effective communication, and assessment and actions - to reduce the incidence of challenging behaviour. In some situations, physical interventions may be required to protect the safety of the individual, healthcare staff and other individuals involved, and healthcare staff should be aware of local policies and procedures for this. Following a serious incident, where there was potential or actual harm to patients and healthcare staff, healthcare organisations should use post incident reviews to learn from the situation, while healthcare staff should be offered the opportunity for debriefing. Positive responses to challenging behaviour at an organisational and individual level can lead to improved work environments for healthcare staff and optimal patient care and outcomes.

AB - No selective drugs exist, and we have been designing, synthesizing, and evaluating multitarget-directed ligands since the beginning of modern medicinal chemistry, without knowing it, most possibly. The challenge to discover the efficient Multi-Target Small Molecules (MTSMs) for Alzheimer's disease (AD) therapy implies to identify the key combination of biological targets to modulate them, thus including in the design the corresponding pharmacophoric groups able to do it. Universal and polyvalent pharmacophoric groups, able to modulate diverse receptors or enzymatic systems, would simplify the drug discovery process leading to new and more efficient MTSMs for AD. PMID- 29465221 TI - Polydopamine Surface Chemistry: A Decade of Discovery. AB - Polydopamine is one of the simplest and most versatile approaches to functionalizing material surfaces, having been inspired by the adhesive nature of catechols and amines in mussel adhesive proteins. Since its first report in 2007, a decade of studies on polydopamine molecular structure, deposition conditions, and physicochemical properties have ensued. During this time, potential uses of polydopamine coatings have expanded in many unforeseen directions, seemingly only limited by the creativity of researchers seeking simple solutions to manipulating surface chemistry. In this review, we describe the current state of the art in polydopamine coating methods, describe efforts underway to uncover and tailor the complex structure and chemical properties of polydopamine, and identify emerging trends and needs in polydopamine research, including the use of dopamine analogs, nitrogen-free polyphenolic precursors, and improvement of coating mechanical properties.

AB - In vitro culture of Plasmodium vivax liver stages underlies key understandings of the fundamental biology of this parasite, particularly the latent, hyponozoite stage, toward drug and vaccine development. Here, we report systematic production of Plasmodium vivax sporozoites in colonized Anopheles darlingi mosquitoes in the Peruvian Amazon. Human subject-derived P. vivax-infected blood was fed to Anopheles darlingi females using standard membrane feedings assays. Optimizing A. darlingi infection and sporozoite production included replacement of infected patient donor serum with naive donor serum, comparing anticoagulants in processing blood samples, and addition of penicillin-streptomycin and ATP to infectious blood meals. Replacement of donor serum by naive serum in the P. vivax donor blood increased oocysts in the mosquito midgut, and heparin, as anticoagulant, was associated with the highest sporozoite yields. Maintaining blood-fed mosquitoes on penicillin-streptomycin in sugar significantly extended mosquito survival which enabled greater sporozoite yield. In this study, we have shown that a robust P. vivax sporozoite production is feasible in a malaria endemic setting where infected subjects and a stable A. darlingi colony are brought together, with optimized laboratory conditions. PMID- 29465222 TI - DNA Nanotechnology-Enabled Drug Delivery Systems. AB - Over the past decade, we have seen rapid advances in applying nanotechnology in biomedical areas including bioimaging, biodetection, and drug delivery. As an emerging field, DNA nanotechnology offers simple yet powerful design techniques for self-assembly of nanostructures with unique advantages and high potential in enhancing drug targeting and reducing drug toxicity. Various sequence programming and optimization approaches have been developed to design DNA nanostructures with precisely engineered, controllable size, shape, surface chemistry, and function. Potent anticancer drug molecules, including Doxorubicin and CpG oligonucleotides, have been successfully loaded on DNA nanostructures to increase their cell uptake efficiency. These advances have implicated the bright future of DNA nanotechnology-enabled nanomedicine. In this review, we begin with the origin of DNA nanotechnology, followed by summarizing state-of-the-art strategies for the construction of DNA nanostructures and drug payloads delivered by DNA nanovehicles. Further, we discuss the cellular fates of DNA nanostructures as well as challenges and opportunities for DNA nanostructure-based drug delivery.

AB - Mixed-valent iron [Fe(II)-Fe(III)] minerals such as magnetite and green rust have received a significant amount of attention over recent decades, especially in the environmental sciences. These mineral phases are intrinsic and essential parts of biogeochemical cycling of metals and organic carbon and play an important role regarding the mobility, toxicity, and redox transformation of organic and inorganic pollutants. The formation pathways, mineral properties, and applications of magnetite and green rust are currently active areas of research in geochemistry, environmental mineralogy, geomicrobiology, material sciences, environmental engineering, and environmental remediation. These aspects ultimately dictate the reactivity of magnetite and green rust in the environment, which has important consequences for the application of these mineral phases, for example in remediation strategies. In this review we discuss the properties, occurrence, formation by biotic as well as abiotic pathways, characterization techniques, and environmental applications of magnetite and green rust in the environment. The aim is to present a detailed overview of the key aspects related to these mineral phases which can be used as an important resource for researchers working in a diverse range of fields dealing with mixed-valent iron minerals.

AB - Three-dimensional (3D) binary oxides with hierarchical porous nanostructures are attracting increasing attentions as electrode materials in energy storage and conversion systems because of their structural superiority which not only create desired electronic and ion transport channels but also possess better structural mechanical stability. Herein, unusual 3D hierarchical MnCo2O4 porous dumbbells have been synthesized by a facile solvothermal method combined with a following heat treatment in air. The as-obtained MnCo2O4 dumbbells are composed of tightly stacked nanorods and show a large specific surface area of 41.30 m2 g-1 with a pore size distribution of 2-10 nm. As an anode material for lithium-ion batteries (LIBs), the MnCo2O4 dumbbell electrode exhibits high reversible capacity and good rate capability, where a stable reversible capacity of 955 mA h g-1 can be maintained after 180 cycles at 200 mA g-1. Even at a high current density of 2000 mA g-1, the electrode can still deliver a specific capacity of 423.3 mA h g-1, demonstrating superior electrochemical properties for LIBs. In addition, the obtained 3D hierarchical MnCo2O4 porous dumbbells also display good oxygen evolution reaction activity with an overpotential of 426 mV at a current density of 10 mA cm-2 and a Tafel slope of 93 mV dec-1.

AB - Stimuli-responsive hydrogels that undergo programmable shape deformation are of great importance for a wide variety of applications spanning from soft robotics and biomedical devices to tissue engineering and drug delivery. To guide shape morphing, anisotropic elements need to be encoded into the hydrogels during fabrication, which are extremely difficult to alter afterward. This study reports a simple and reliable mechanochemical regulation strategy to postengineer the hydrogels by encoding structures of high stiffness locally into prestretched tough hydrogels through ion transfer printing with a paper-cut. During printing, trivalent ions (Fe3+) were patterned and diffused into the prestretched tough gels, which dramatically increased the local stiffness by forming the second trivalent ionically cross-linked network. By removing the applied stretching force, the stiff anisotropy-encoded prestretched tough hydrogels underwent programmable shape morphing into complex three-dimensional origami structures due to the stiffness mismatch. PMID- 29465226 TI - Data-Independent Acquisition Coupled to Visible Laser-Induced Dissociation at 473 nm (DIA-LID) for Peptide-Centric Specific Analysis of Cysteine-Containing Peptide Subset. AB - Thanks to comprehensive and unbiased sampling of all precursor ions, the interest to move toward bottom-up proteomic with data-independent acquisition (DIA) is continuously growing. DIA offers precision and reproducibility performances comparable to true targeted methods but has the advantage of enabling retrospective data testing with the hypothetical presence of new proteins of interest. Nonetheless, the chimeric nature of DIA MS/MS spectra inherent to concomitant transmission of a multiplicity of precursor ions makes the confident identification of peptides often challenging, even with spectral library-based extraction strategy. The introduction of specificity at the fragmentation step upon ultraviolet or visible laser-induced dissociation (LID) range targeting only the subset of cysteine-containing peptides (Cys-peptide) has been proposed as an option to streamline and reduce the search space. Here, we describe the first coupling between DIA and visible LID at 473 nm to test for the presence of Cys peptides with a peptide-centric approach. As a test run, a spectral library was built for a pool of Cys-synthetic peptides used as surrogates of human kinases (1 peptide per protein). By extracting ion chromatograms of query standard and kinase peptides spiked at different concentration levels in an Escherichia coli proteome lysate, DIA-LID demonstrates a dynamic range of detection of at least 3 decades and coefficients of precision better than 20%. Finally, the spectral library was used to search for endogenous kinases in human cellular extract.

AB - The extensive use of sulfonamides (SNs) in animal husbandry has led to an unintentional widespread occurrence in several environmental compartments. The implementation of regulations and management recommendations to reduce the potential risk of development of antibiotic resistances necessitates detailed knowledge on their fate in soil. We present results from two independent incubation studies of 15N-labeled sulfadiazines (SDZ) which focused on identifying binding types in bound residues. In the first study 15N-amino labeled SDZ was incubated with two previously isolated humic acids in the presence and absence of Trametes versicolor laccase, while in the second study 15N-double labeled SDZ was incubated with a typical agricultural Luvisol and the humic acid fraction isolated after sequential extraction of the soil. The freeze-dried humic acid fractions of both studies were then analyzed by 15N-CPMAS NMR and compared with the 15N-spectra of synthesized model compounds. In both studies amide bonds and Michael adducts were identified, while formation of imine bonds could be excluded. In the humic acid study, where less harsh extraction methods were applied, possible formation of H-bridging and sequestration were additionally detected.

AB - While solid-state nuclear magnetic resonance (ssNMR) has emerged as a powerful technique for studying viral capsids, current studies are limited to capsids formed from single proteins or single polyproteins. The ability to selectively label individual protein components within multiprotein viral capsids and the resulting spectral simplification will facilitate the extension of ssNMR techniques to complex viruses. In vitro capsid assembly by combining individually purified, labeled, and unlabeled components in NMR quantities is not a viable option for most viruses. To overcome this barrier, we present a method that utilizes sequential protein expression and in cell assembly of component specifically labeled viral capsids in amounts suitable for NMR studies. We apply this approach to purify capsids of bacteriophage phi6 isotopically labeled on only one of its four constituent protein components, the NTPase P4. Using P4 labeled phi6 capsids and the sensitivity enhancement provided by dynamic nuclear polarization, we illustrate the utility of this method to enable ssNMR studies of complex viruses.

AB - Various hydrogels have been used for protein delivery in the treatment of human diseases. Nevertheless, it is always difficult to control the capture and release of multiple proteins in different regions and periods. This research successfully proves that multiple proteins can be captured and released from the aptamer patterned hydrogel films with an adjustable release rate at a prospective time and in specific regions utilizing the complementary DNA strand of aptamers via photoclick chemistry and DNA hybridization. The hydrogel film is successfully applied to complex matrixes such as human serum and has excellent cytocompatibility. Thus, the aptamer-patterned hydrogel film will be a good candidate for controlled delivery of multiple proteins. PMID- 29465231 TI - Ab Initio Nonadiabatic Quantum Molecular Dynamics. AB - The Born-Oppenheimer approximation underlies much of chemical simulation and provides the framework defining the potential energy surfaces that are used for much of our pictorial understanding of chemical phenomena. However, this approximation breaks down when the dynamics of molecules in excited electronic states are considered. Describing dynamics when the Born-Oppenheimer approximation breaks down requires a quantum mechanical description of the nuclei. Chemical reaction dynamics on excited electronic states is critical for many applications in renewable energy, chemical synthesis, and bioimaging. Furthermore, it is necessary in order to connect with many ultrafast pump-probe spectroscopic experiments. In this review, we provide an overview of methods that can describe nonadiabatic dynamics, with emphasis on those that are able to simultaneously address the quantum mechanics of both electrons and nuclei. Such ab initio quantum molecular dynamics methods solve the electronic Schrodinger equation alongside the nuclear dynamics and thereby avoid the need for precalculation of potential energy surfaces and nonadiabatic coupling matrix elements. Two main families of methods are commonly employed to simulate nonadiabatic dynamics in molecules: full quantum dynamics, such as the multiconfigurational time-dependent Hartree method, and classical trajectory based approaches, such as trajectory surface hopping. In this review, we describe a third class of methods that is intermediate between the two: Gaussian basis set expansions built around trajectories.

The second portion of this Viewpoint showcases the historical developments in using these molecules for applications ranging from materials science to medicine. Last, we suggest potential new directions for these clusters as they apply to both synthetic methods and applications.

AB - A competitive-displacement reaction strategy based on target-induced dissociation of gold nanoparticle coated graphene nanosheet (AuNPs/GN) from CdS quantum dot functionalized mesoporous titanium dioxide (CdS QDs/TiO2) was designed for the sensitive photoelectrochemical (PEC) aptasensing of prostate-specific antigen (PSA) through the exciton-plasmon interaction (EPI) between CdS QDs and AuNPs. To construct such an aptasensing system, capture DNA was initially conjugated covalently onto CdS QDs/TiO2-modified electrode, and then AuNPs/GN-labeled PSA aptamer was bound onto biofunctionalized CdS QDs/TiO2 via hybridization chain reaction of partial bases with capture DNA. Introduction of AuNPs/GN efficiently quenched the photocurrent of CdS QDs/TiO2 thanks to energy transfer. Upon addition of target PSA, the sandwiched aptamer between CdS QDs/TiO2 and AuNPs/GN reacted with the analyte analyte, thus resulting in the dissociation of AuNPs/GN from the CdS QDs/TiO2 to increase the photocurrent. Under optimum conditions, the aptasensing platform exhibited a high sensitivity for PSA detection within a dynamic linear range of 1.0 pg/mL to 8.0 ng/mL at a low limitat of detection of 0.52 pg/mL. The interparticle distance of exciton-plasmon interaction and contents of AuNPs corresponding to EPI effect in this system were also studied. Good selectivity and high reproducibility were obtained for the analysis of target PSA. Importantly, the accuracy and matrix effect of PEC aptasensor was evaluated for the determination of human serum specimens and newborn calf serum diluted PSA standards, giving a well-matched result with the referenced PSA ELISA kit. PMID- 29465233 TI - Forward Osmosis Membranes under Null-Pressure Condition: Do Hydraulic and Osmotic Pressures Have Identical Nature? AB - Forward osmosis (FO) membranes fall into the category of nonporous membranes, based on the assumption that water and solute transport occur solely based on diffusion. The solution-diffusion (S-D) model has been widely used in predicting their performances in the coexistence of hydraulic and osmotic driving forces, a model that postulates the hydraulic and osmotic driving forces have identical nature. It was suggested, however, such membranes may have pores and mass transport could occur both by convection (i.e., volumetric flow) as well as by diffusion assuming that the dense active layer of the membranes is composed of a nonporous structure with defects which induce volumetric flow through the membranes. In addition, the positron annihilation technique has revealed that the active layers can involve relatively uniform porous structures. As such, the assumption of a nonporous active layer in association with hydraulic pressure is questionable. To validate this assumption, we have tested FO membranes under the conditions where hydraulic and osmotic pressures are equivalent yet in opposite directions for water transport, namely the null-pressure condition. We have also established a practically valid characterization method which quantifies the vulnerability of the FO membranes to hydraulic pressure.

PMID- 29465235 TI - Postsynthetic Addition of Ligand Struts in Metal-Organic Frameworks: Effect of Syn/Anti Addition on Framework Structures with Distinct Topologies. AB - For the parent metal-organic framework (MOF) of UiO-type 1, postsynthetic bromination (anti addition) was readily carried out on the stilbene-ligand struts by directly adding excess bromine, whereas successful hydrogenation (syn addition) can only be achieved by slowing the reaction rate; otherwise, the crystalline structure of 1 will be irreversibly damaged. Meanwhile, Kagome-like MOF 2 can be smoothly modified by both postsynthetic bromination and hydrogenation. This study of the structural conversion not only represents the first example that adopts postsynthetic hydrogenation for modifying MOFs but also reveals various factors such as the reaction manner of syn/anti, framework topology, and reaction rate that can influence postsynthetic modification on the ligand struts of MOFs. PMID- 29465236 TI - Exploring Nuclear Photorelaxation of Pyranine in Aqueous Solution: an Integrated Ab-Initio Molecular Dynamics and Time Resolved Vibrational Analysis Approach. AB - Advances in time-resolved vibrational spectroscopy techniques provided a new stimulus for understanding the transient molecular dynamics triggered by the electronic excitation. The detailed interpretation of such time-dependent spectroscopic signals is a challenging task from both experimental and theoretical points of view. We simulated and analyzed the transient photorelaxation of the pyranine photoacid in aqueous solution, with special focus on structural parameters and low frequency skeleton modes that are possibly preparatory for the photoreaction occurring at later time, as suggested by experimental spectroscopic studies. To this aim, we adopted an accurate computational protocol that combines excited state ab initio molecular dynamics within an hybrid quantum mechanical/molecular mechanics framework and a time resolved vibrational analysis based on the Wavelet transform. According to our results, the main nuclear relaxation on the excited potential energy surface is completed in about 500 fs, in agreement with experimental data. The rearrangement of C-C bonds occurs according to a complex vibrational dynamics, showing oscillatory patterns that are out of phase and modulated by modes below 200 cm-1. We also analyzed in both the ground and the excited state the evolution of some structural parameters involved in excited state proton transfer reaction, namely, those involving the pyranine and the water molecule hydrogen bonded to the phenolic O-H group. Both the hydrogen bond distance and the intermolecular orientation are optimized in the excited state, resulting in a tighter proton donor-acceptor couple. Indeed, we found evidence that collective low frequency skeleton modes, such as the out of plane wagging at 108 cm-1 and the deformation at 280 cm-1, are photoactivated by the ultrafast part of the relaxation and modulate the pyranine-water molecule rearrangement, favoring the preparatory step for the photoreactivity. PMID- 29465238 TI - Orbital Symmetry and the Optical Response of Single-Layer MX Monochalcogenides. AB - We show that the absorption spectra of single-layer GaSe and GaTe in the hexagonal phase feature exciton peaks with distinct polarization selectivity. We investigate these distinct features from first-principles calculations using the GW-BSE formalism. We show that, because of the symmetry of the bands under in plane mirror symmetry, the bound exciton states selectively couple to either in plane or out-of-plane polarization of the light. In particular, for a p-polarized light absorption experiment, the absorption peaks of the hydrogenic s-like excitons emerge at large angle of incidence, while the overall absorbance reduces over the rest of the spectrum.

AB - The development of synthetic analogs of the active sites of [NiFe] hydrogenases remains challenging, and, in spite of the number of complexes featuring a [NiFe] center, those featuring CO and CN- ligands at the Fe center are under represented. We report herein the synthesis of three bimetallic [NiFe] complexes [Ni( N2 S2)Fe(CO)2(CN)2], [Ni( S4)Fe(CO)2(CN)2], and [Ni( N2 S3)Fe(CO)2(CN)2] that each contain a Ni center that bridges through two thiolato S donors to a {Fe(CO)2(CN)2} unit. X-ray crystallographic studies on [Ni( N2 S3)Fe(CO)2(CN)2], supported by DFT calculations, are consistent with a solid-state structure containing distinct molecules in the singlet ( S = 0) and triplet ( S = 1) states. Each cluster exhibits irreversible reduction processes between -1.45 and 1.67 V vs Fc+/Fc and [Ni( N2 S3)Fe(CO)2(CN)2] possesses a reversible oxidation process at 0.17 V vs Fc+/Fc. Spectroelectrochemical infrared (IR) and electron paramagnetic resonance (EPR) studies, supported by density functional theory (DFT) calculations, are consistent with a NiIIIFeII formulation for [Ni( N2 S3)Fe(CO)2(CN)2]+. The singly occupied molecular orbital (SOMO) in [Ni( N2 S3)Fe(CO)2(CN)2]+ is based on Ni 3dz2 and 3p S with the S contributions deriving principally from the apical S-donor. The nature of the SOMO corresponds to that proposed for the Ni-C state of the [NiFe] hydrogenases for which a NiIIIFeII formulation has also been proposed. A comparison of the experimental structures, and the electrochemical and spectroscopic properties of [Ni( N2 S3)Fe(CO)2(CN)2] and its [Ni( N2 S3)] precursor, together with calculations on the oxidized [Ni( N2 S3)Fe(CO)2(CN)2]+ and [Ni( N2 S3)]+ forms suggests that the binding of the {Fe(CO)(CN)2} unit to the {Ni(CysS)4} center at the active site of the [NiFe] hydrogenases suppresses thiolate-based oxidative chemistry involving the bridging thiolate S donors. This is in addition to the role of the Fe center in modulating the redox potential and geometry and supporting a bridging hydride species between the Ni and Fe centers in the Ni-C state.

PMID- 29465240 TI - Competitive Halogen Bond in the Molecular Ferroelectric with Large Piezoelectric Response. AB - Molecular piezoelectrics are attracting tremendous interest because of their easy processing, light weight, low acoustical impedance, and mechanical flexibility. However, reports of molecular piezoelectrics with a piezoelectric coefficient d33 comparable to piezoceramics such as barium titanate (BTO, 90-190 pC/N) have been scarce. Here, we present a uniaxial molecular ferroelectric, trimethylchloromethylammonium tribromocadmium(II) (TMCM-CdBr3), in which the halogen bonding might be a possible critical point for the stabilization of one dimensional (1D) {CdBr3}- chain and further reservation of its ferroelectricity in such organic-inorganic hybrid crystalline systems. It has a large d33 of 139 pC/N, 1 order of magnitude higher than those of most classically uniaxial ferroelectrics such as LiNbO3 (6-16 pC/N) and Rochelle salt (~7 pC/N), and comparable with those of multiaxial ferroelectrics such as BTO and trimethylbromomethylammonium tribromomanganese(II) (112 pC/N). Moreover, the simple single-crystal growth and easy-to-find polar axis enable it to hold a great potential for applying in the single-crystal form. In light of the strong, specific, and directional halogen-bonding interactions, this work provides possibilities to explore new classes of molecular piezoelectrics and contribute to further developments. PMID- 29465241 TI - Response of Membranes and Vesicles to Capillary Forces Arising from Aqueous Two Phase Systems and Water-in-Water Droplets. AB - Aqueous two-phase systems and water-in-water emulsions have attracted much recent interest. Here, we theoretically study the interactions of such systems with biomimetic membranes and giant unilamellar vesicles (GUVs). For partial wetting, the water-water interface and the membrane form a three-phase contact line that partitions the membrane into two distinct segments with different tensions and different curvature-elastic properties. On the nanometer scale, the capillary forces arising from the water-water interface lead to a smoothly curved membrane that forms an intrinsic contact angle with the interface. The corresponding balance conditions are derived here for general curvature-elastic parameters of the two membrane segments. On the micrometer scale, the capillary forces deform the membrane segments into spherical caps with an apparent kink along the contact line. A new computational method is introduced by which these piece-wise spherical vesicle shapes can be analyzed in a systematic manner. The method is based on a general relationship that is reminiscent of Neumann's triangle but depends explicitly on the curvatures of the membrane segments. For certain regions of the parameter space, corresponding to small or large spontaneous curvatures, the force balance along the apparent contact line can be described in a self-consistent manner and then leads to curvature-independent relationships that involve the total membrane tensions. The different relationships can be used to determine the material parameters of the droplet-vesicle system from the observed morphologies of the GUVs. The approach described here is quite general and can be applied to different membrane compositions and aqueous two-phase systems. The same computational approach can also be used to elucidate the response of biological membranes to the recently discovered membrane-less, droplet-like organelles.

AB - The interfacial phenomena at liquid-liquid interfaces remain the subject of constant fascination in science and technology. Here, we show that fingers forming at the interface of nonequilibrium all-aqueous systems can spontaneously break into an array of droplets. The dynamic formation of droplets at the water water (w/w) interface is observed when a less dense aqueous phase, for instance, the dextran solution, is placed on a denser aqueous phase, the polyethylene glycol solution, in a vertical Hele-Shaw cell. Because of the gradual diffusion of water from the upper phase into the lower phase, a dense layer appears at the nonequilibrium w/w interface. As a result, a periodic array of fingers emerge and sink. Remarkably, these fingers break up and an array of droplets are emitted from the interface. We characterize the wavelength of fingering by measuring the average distance between the dominant fingers. By varying the initial concentrations of the two nonequilibrium aqueous phases, we identify experimentally a phase diagram with a wide parameter space in which finger breaking occurs. Finally, plenty of droplets, spontaneously formed when one phase is continuously deposited onto another aqueous phase, further confirm the robustness of our experimental results. Our work suggests a simple yet efficient approach with a potential upscalability to generate all-aqueous droplets.

AB - Ruthenium-based complexes are widely used as photocatalysts, as photosensitizers, or as building blocks for supramolecular assemblies. In the field of solar energy conversion, building light harvesting antenna is of prime interest. Nevertheless, collecting light is mandatory but not sufficient; once collected and transferred, the exciton has to be long-lived enough to be transferred to a catalytic site. If Ru(II) terpyridine complexes are prime building blocks for structural reasons, the short lifetime of their excited state prevents their use as a harvesting center in light antennae. In this paper, we present new polynuclear assemblies, based on Ru(II)-terpyridine units where delocalization of the excited state is combined with an antenna effect. As a consequence, complexes C1-C3 display long lived excited states compared to [Ru(tpy)2]2+, making them promising efficient antenna building blocks to be connected to a final acceptor or a catalytic center. PMID- 29465244 TI - Study of Meldrum's Acid Cyclization Reactions. AB - On the basis of the cyclization reactions reported by Danishefsky et al. of Meldrum's acid hydroxylethyl and anilinoethyl derivatives, the cyclization of the sulfamidomethylene and ureidomethylene derivatives was attempted without success. To understand the lack of reactivity of these compounds versus the successful cyclization of the ethyl derivatives, the corresponding mechanisms of reaction for both processes have been explored by means of MP2/6-311+G(d,p) calculations in an aqueous environment. The conformational analysis of all of these structures revealed that, while for the ethyl derivatives the minimum energy conformation corresponds to that of the cyclization initiating structure, for the methylene analogues the entrance channel conformations are substantially less stable than the energy minimum. Intramolecular hydrogen bonds were found in all of the energy minima as well as in the cyclization initiating conformations as determined by analysis of their electron density. The potential energy surfaces for the successful and unsuccessful cyclization processes were obtained at room temperature and 100 degrees C. Comparison of both processes allows rationalization that the lack of reactivity of the methylene derivatives can be thermodynamically explained based not only on the strength of the intramolecular hydrogen bond formed in their energy minima but also by the energy penalty needed to reach the entrance channel conformation and by the calculated energy barriers. PMID- 29465245 TI - Electronic Level Alignment at an Indium Tin Oxide/PbI2 Interface and Its Applications for Organic Electronic Devices. AB - The electronic level alignment at the indium tin oxide (ITO)/PbI2 interface is investigated by an ultraviolet photoelectron spectroscopy. An n-type conductivity property is found for PbI2 as well as a downward shift energy level at the ITO/PbI2 interface. These indicate that PbI2 can be used as an anode buffer layer for organic electronic devices. The power conversion efficiency of the organic solar cell based on tetraphenyldibenzoperiflanthene/C70 planar heterojunction is dramatically increased from 1.05 to 3.82%. Meanwhile, the thermally activated delayed fluorescence organic light-emitting diode based on 4,4',4"-tri( N carbazolyl)triphenylamine-((1,3,5-triazine-2,4,6-triyl)tris(benzene-3,1 diyl))tris(diphenylphosphine oxide) shows a significantly reduced turn-on voltage and enhanced power efficiency from 6.26 to 18.60 lm/W. The improved performance is attributed to the high hole injection/extraction efficiency at the ITO/PbI2 interface. Besides, the near-infrared (NIR) absorption of lead phthalocyanine (PbPc)-based NIR organic photodetector (NIR-OPD) is dramatically increased, indicating that the PbI2 layer can also be used as a template layer for the growth of the triclinic phase of PbPc. As a result, the optimized device shows an external quantum efficiency of 26.7% and a detectivity of 9.96 * 1011 jones at 900 nm, which are among the highest ones reported for organic NIR-OPDs. PMID- 29465246 TI - Hybrid Dion-Jacobson 2D Lead Iodide Perovskites. AB - The three-dimensional hybrid organic-inorganic perovskites have shown huge potential for use in solar cells and other optoelectronic devices. Although these materials are under intense investigation, derivative materials with lower dimensionality are emerging, offering higher tunability of physical properties and new capabilities. Here, we present two new series of hybrid two-dimensional (2D) perovskites that adopt the Dion-Jacobson (DJ) structure type, which are the first complete homologous series reported in halide perovskite chemistry. Lead iodide DJ perovskites adopt a general formula A'A n-1Pb nI3 n+1 (A' = 3 (aminomethyl)piperidinium (3AMP) or 4-(aminomethyl)piperidinium (4AMP), A = methylammonium (MA)). These materials have layered structures where the stacking of inorganic layers is unique as they lay exactly on top of another. With a slightly different position of the functional group in the templating cation 3AMP and 4AMP, the as-formed DJ perovskites show different optical properties, with the 3AMP series having smaller band gaps than the 4AMP series. Analysis on the crystal structures and density functional theory (DFT) calculations suggest that the origin of the systematic band gap shift is the strong but indirect influence of the organic cation on the inorganic framework. Fabrication of photovoltaic devices utilizing these materials as light absorbers reveals that (3AMP)(MA)3Pb4I13 has the best power conversion efficiency (PCE) of 7.32%, which is much higher than that of the corresponding (4AMP)(MA)3Pb4I13. PMID- 29465247 TI - Viability of single balloon enteroscopy performed under endoscopist-directed sedation. AB - INTRODUCTION: there is a lot of controversy with regard to who should be responsible for sedation during digestive endoscopy, particularly in advanced procedures that require deep sedation such as enteroscopy. The aim of this study was to evaluate the endoscopist-directed sedation viability during single balloon enteroscopy. MATERIAL AND METHOD: this was a prospective, observational study of a series of consecutive enteroscopies. The clinical staff included an endoscopist, scrub nurse and a nurse in charge of monitoring and sedative administration. The following parameters were monitored: pulse oximetry, blood pressure (every five minutes), electrocardiogram and respiratory rate. There was continuous supplemental oxygen and CO2 insufflation. The patient was in the left lateral decubitus position and a fluoroscopic control was used. RESULTS: forty four explorations were performed in 39 patients, 24 were male and 15 female. The median age was 74 (18-89) and the ASA score was I in 12 cases, II in 23 cases and III in nine cases. Comorbidities were present in 68% of cases. The drugs used included propofol in 23 cases, propofol and midazolam in ten cases, propofol/midazolam/fentanyl in two cases, propofol and fentanyl in two cases, and midazolam/fentanyl in seven cases. All procedures were complete. The length of the procedure was 52 minutes (20-120). There were diagnostic findings in 65.9% of cases and therapeutic measures in 47.7%. There were no severe complications and the rate of complications derived from sedation was 22.7%. CONCLUSION: endoscopist-directed sedation is effective and safe for single balloon enteroscopy. Multi-center and wider studies are needed in order to better assess the efficacy, safety and efficiency of sedation controlled by a non-anesthetist during advanced endoscopy in this field. PMID- 29465248 TI - Quality of sedation with propofol administered by non-anesthetists in a digestive endoscopy unit: the results of a one year experience. AB - INTRODUCTION: research has shown that an endoscopist-nurse clinical team can perform sedation with propofol effectively, safely and efficiently. To do so, it is essential to provide specific and appropriate training in the necessary skills. The main aim of the present study was to evaluate the quality of the sedation procedure administered by non-anesthetists in a digestive endoscopy unit, one year after its introduction. METHODS: a prospective cohort study was performed in patients given propofol sedation by non-anesthetists. Subsequently, a random sample of clinical records was selected in order to evaluate the adherence of professionals to the quality criteria and to assess the rate of adverse events related to sedation. RESULTS: a total of 595 procedures were performed under propofol sedation during the study period. The rate of adverse events was 2.4% (n = 507), mainly involving hypotension and hypoxemia. Adherence to the sedation procedure was above 80% for most of the applicable criteria, although it was lower for the completion of ASA risk evaluation. CONCLUSIONS: the results of the study suggest that propofol can be administered safely and effectively by a qualified endoscopist-nurse team, in patients with an ASA I-II risk. Audits of adherence by medical staff to the recommended procedure facilitate the identification of areas for improvement; further work is needed on the aspects that have not yet been consolidated. PMID- 29465249 TI - The right colon challenge. AB - Colorectal cancer (CRC) is the third most common cancer and the fourth cause of cancer-related mortality worldwide. In an attempt to raise awareness on this situation, and to implement preventive measures, March 31st has been established as international colorectal cancer awareness day. Our country, with the Spanish "Alianza para la Prevencion del Cancer de Colon", pioneered in 2008 an institution that brought together scientific and civil societies to pursue this goal. A stabilization, even a decrease in the incidence and mortality of this condition has been reported in western countries for the last few years, which may be attributed to a number of highly relevant factors. PMID- 29465250 TI - Continuous esomeprazole infusion versus bolus administration and second look endoscopy for the prevention of rebleeding in children with a peptic ulcer. AB - INTRODUCTION: the majority of studies of acute gastrointestinal bleeding in children are retrospective, focusing on therapeutic endoscopy. Previous studies performed in adult patients have demonstrated that both scheduled second look endoscopy and high dose continuous omeprazole infusion are effective in the prevention of peptic ulcer rebleeding. The aim of this study was to compare the efficacy of these two strategies using esomeprazole for the prevention of rebleeding following primary endoscopic hemostasis in children with peptic ulcers. The main outcome was to assess the rebleeding rate within 30 days after the initial hemostasis. METHODS: consecutive pediatric cases who underwent endoscopic treatment for bleeding peptic ulcers were randomized into two treatment groups following hemostasis. The first group received esomeprazole as an intravenous bolus every 12 hours for 72 hours and a routine second look endoscopy within 12-24 hours with endotherapy retreatment in the case of a persistent stigmata of bleeding. The second group received a continuous high dose esomeprazole infusion for 72 hours without endoscopic reassessment unless required due to rebleeding. RESULTS: a total of 63 children were randomized to the second look endoscopy group and 64 to the esomeprazole infusion group. Rebleeding occurred within 30 days in four patients (6.3%) in the first group and in three patients (4.6%) in the second group (p = 0.7). CONCLUSIONS: a pharmaceutical approach using a high dose continuous esomeprazole infusion in children after an initial endoscopic hemostasis has a similar efficacy compared to second look endoscopy and bolus esomeprazole administration for the prevention of peptic ulcer rebleeding. Thus, the discomfort of a second endoscopy in children can be avoided and is only recommended for selected high risk cases. PMID- 29465251 TI - Managing iron deficiency and iron deficiency anemia in inflammatory bowel disease. The results of the "Gestiona hierro-EII" survey. AB - INTRODUCTION: iron deficiency anemia is a common and very relevant manifestation of inflammatory bowel disease (IBD). Although clinical practice guidelines have been published and updated on this subject, the management in the daily practice of this complication is far from optimal. OBJECTIVE: to determine the actual management, needs and limitations of anemia in IBD by means of a survey of gastroenterology specialists. MATERIAL AND METHODS: a self-administered telematic survey was carried out between April and May 2017 and was sent to SEPD members. The survey included four sections: participant demographics, monitoring, treatment and limitations/needs. RESULTS: a total of 122 evaluable surveys were received from all Spanish autonomous communities. Iron deficiency anemia is considered as a frequent manifestation of IBD and is monitored in all patients via the measurement of hemoglobin and ferritin. In the case of anemia, the survey respondents found it necessary to rule out the presence of IBD activity. However, only 14.8% prescribed intravenous iron when IBD was active. The required dose of intravenous iron is mainly calculated according to patient needs but only 33.1% of clinicians infused doses of 1 g or more. CONCLUSIONS: the "Gestiona Hierro EII" survey on the management of anemia in IBD demonstrated a high quality of care, even though some aspects need to be improved. These included the prescription of intravenous iron for patients with disease activity, the use of high-dose intravenous iron and the implementation of algorithms into clinical practice.

AB - The goal of comparative effectiveness research (CER) and patient-centered outcomes research (PCOR) is to improve health outcomes by providing stakeholders with evidence directly relevant to decision making. In January 2017, the Pharmaceutical Research and Manufacturers Association Foundation, alongside the Academy for Managed Care Pharmacy, organized a conference aimed at engaging experts and opinion leaders representing clinicians, patients and payers to identify and discuss barriers and strategies to enhancing uptake and use of CER/PCOR. This report summarizes the conference discussion in the following sections: preconference survey; summary of barriers and strategies to the uptake of CER/PCOR identified by conference attendees; and future perspectives on the field. PMID- 29465253 TI - Nanocrystal: a novel approach to overcome skin barriers for improved topical drug delivery. AB - INTRODUCTION: Skin is an important route of drug delivery for the treatment of various dermatological conditions. The advent of nanotechnology is paving the roadmaps for topical drug delivery by providing sustained release as well as maintaining a localized effect, outweighing the toxicity concern. Area covered: This review highlighted the morphology of skin, its barrier nature as well as drug penetration pathways after topical application of formulations. The existing methods to improve topical drug delivery, by infringing or permeating the skin barriers, are discussed. This context concretes the foundation to accentuate the need for the development of nanocrystal-based topical formulation. The mechanism of drug release, immediate as well as sustained release, after topical administration of drug nanocrystals is also elaborated. The special emphasis is given on the breakthrough achieved, in topical drug delivery using drug nanocrystals, so far in the plethora of literature, patents, and products, under clinical trial as well as in the market. Expert opinion: The current research on nanocrystals for topical drug delivery is highlighting the breakthroughs achieved so far. The output of these research envisages that topical nanocrystals based formulations can be a novel strategy for the drugs which are facing solubility, bioavailability and toxicity concerns. PMID- 29465254 TI - Type and doses of oral anticoagulants and adherence to anticoagulant treatment in elderly patients with atrial fibrillation: the ESPARTA study. AB - AIM: To analyze the use of oral anticoagulants in elderly patients with atrial fibrillation in clinical practice. PATIENTS & METHODS: Cross-sectional and multicenter study performed in atrial fibrillation patients >=75 years treated with oral anticoagulants >=3 months. RESULTS: 837 patients (83.0 +/- 5.0 years; CHA2DS2-VASc 5.0 +/- 1.4; HAS-BLED 2.1 +/- 0.9; 70.8% vitamin K antagonists; 29.2% direct oral anticoagulants [DOACs]) were included. Poor adherence was observed in 27.9% of patients. Higher scores in the Pfeiffer's test and FRAIL scale were associated with poorer adherence. Among patients treated with DOACs, 62.3% received the lower doses. Having high CHADS2 score and being older were associated with the use of low doses. CONCLUSION: 28% of patients had a poor adherence to anticoagulant treatment. 62% of patients were treated with the lower doses of DOACs.

AB - In this essay, the author reflects on how biomedical and gendered perceptions of reproductive health can impact an illness experience. Using a narrative lens, she relays the frustration of attempting to have her excessive menstrual pain legitimated and treated when loved ones and medical professionals trivialized it and refused to let her take on the sick role. She recounts incidents that demonstrate the embedded and limiting persistence of gendered perceptions of pain. In the end, she argues that only through strong patient self-advocacy and knowledge can one rewrite the social scripts assigned to how women cope with menstrual pain. PMID- 29465256 TI - Managing Anti-Fat Stigma in Primary Care: An Observational Study. AB - : In many wealthy countries, fatness is stigmatized as a sign of personal failure. Health care interactions can enact fat-related stigmatization, which can worsen health outcomes. The present analysis highlights how stigmatizing discourses about fat bodies emerge in primary care appointments, and examines immediate conversational effects. METHODS: Observational study in three primary care clinics in Canada, using conversation and discourse analytic methods on transcripts of 29 audio-recorded appointments with adults. Talk about weight and blood pressure are contrasted. RESULTS: During measurement and review of measurements, clinicians routinely interpreted the blood pressure result but rarely interpreted weight. Patients of varied ages and body sizes often filled the interpretative vacuum, and focused on behaviors. Overall, neither patients nor clinicians challenged the stigmatizing discourses associated with fat bodies, but sometimes agreed that the "personal failure" frame associated with fatness does not apply to the particular patient. Physicians rarely raised other determinants of weight, but often did so when talking about blood pressure. CONCLUSIONS: Across most body types and ages, weight-related talk spurred stigma management from adult patients. Patients' interpretations were consistent with accepting or avoidant strategies to manage stigma. The findings challenge clinicians and researchers to frame patients' defensiveness or sensitivity as a predictable response to mitigate stigma, and consider how clinical care might be better structured to avoid stigmatization. Recognizing the range of determinants of weight with interpretation of weight may help, particularly if combined with other methods to de-stigmatize care. The results have implications for clinical weight management and behavior change support. PMID- 29465257 TI - Investigational drugs in development to prevent neuromyelitis optica relapses. AB - INTRODUCTION: In the short time since 2014, three pivotal, worldwide studies in neuromyelitis optica spectrum disorders have been launched: eculizumab, SA237 and inebelizumab, each based on a unique mechanism. Areas covered: In this review, we provide a discussion on the trial data available for each drug, a brief description of the trial design, and our expert opinion on the potential benefits and risks. Expert opinion: Eculizumab, a C5 complement inhibitor, may prove useful in the treatment of intractable cases of NMOSD, but physicians must be aware of the known risk of meningococcal infection. SA237, an interleukin-6 receptor blocker, may be effective at reducing relapse risk, and also has the potential to reduce neuropathic pain in NMOSD. Inebelizumab, a B cell depleting agent, has never been tested in NMOSD, but based on extensive evidence of efficacy with B cell depletion using rituximab, inebelizumab is expected to work at least as well. PMID- 29465258 TI - Administration of low-molecular-weight heparin in patients with two or more unsuccessful IVF/ICSI cycles: a multicenter cohort study. AB - To compare the effects of the administration of low-molecular-weight heparin (LMWH) in subfertile patients with two or more unsuccessful IVF/ICSI cycles. In this six-center two-arm retrospective cohort study, the study population (230 women) underwent a GnRH-antagonist protocol and was classified into two groups, according to the couse of LMWH or not. Groups were compared regarding the clinical and IVF/ICSI cycle characteristics and reproductive outcomes, whereas clinical pregnancy and miscarriage constituted the primary endpoints. Logistic regression analysis was performed to determine the potential predictors of clinical pregnancy, miscarriage and live birth rates using the Enter method. Baseline characteristics were comparable in the two groups. There was no statistically significant difference between the two study groups with regard neither to clinical pregnancy and miscarriage rates (33/133 vs. 20/97, p = .456 and 15/133 vs. 9/97, p = .624, respectively), nor to the secondary outcomes preset for this study (all p values >.05). Logistic regression revealed that age of the woman and ICSI and dose of gonadotrophins used were predictors of clinical pregnancy and live birth, respectively. In conclusion, there is no evidence to support the standard addition of LMWH in patients with two or more unsuccessful IVF/ICSI cycles. PMID- 29465259 TI - Latent tuberculosis in childhood: tolerability of two different therapeutic approaches. AB - BACKGROUND: Isoniazid monotherapy for six or nine months and the combination of isoniazid and rifampicin for three or four months are the most used regimens for treating latent tuberculosis. The main aim of this retrospective study is to evaluate the safety of latent tuberculosis treatment by analysing side effects in both regimens. RESEARCH DESIGN AND METHODS: Children with latent tuberculosis and treated with isoniazid or isoniazid and rifampicin were included. Periodic evaluations with clinical assessment and blood exams were carried out to detect any adverse reaction, including elevated serum transaminases. RESULTS: 441 children were included, 14.5% treated with isoniazid and 85.5% with isoniazid and rifampicin. Five patients under combined treatment developed hepatotoxicity within the first month. None of the patients under isoniazid monotherapy presented hepatotoxicity. A slight increase of transaminases level was found in both groups (18.7% in isoniazid and 10.3% in isoniazid/rifampicin groups, respectively) without causing discontinuation of treatment, with values normalization at the subsequent checks. CONCLUSIONS: Both regimens resulted safe. Hepatotoxicity occurred rarely and within the first month. For this reason, it may be appropriate to perform liver function tests after about one month from the beginning of therapy to avoid diagnostic delays.

AB - The purpose of this simulation study was to analyze the effect of variation in Knee-Ankle-Foot-Orthosis stiffness on the joint power and the energy cost of walking. The effect of contractile tissue was simulated using linear elastic spring and viscous dampers in knee and ankle joints. Then, joint angles, ground reaction force, were collected from Twenty chronic hemiparesis subjects (15 males and 5 females) and twenty control subjects (14 males and 6 females), and spring stiffness were considered as the inputs. In this new study, the generated muscle torques were optimized by changing the stiffness as the desired output in the mathematical model attained by the MATLAB SimMechanics toolbox. Finally, the simulated mathematical model was introduced as an appropriate substitute in obtaining the optimized stiffness with a more convenient and efficient designed orthosis. PMID- 29465261 TI - Lipid Synthesis Is Required to Resolve Endoplasmic Reticulum Stress and Limit Fibrotic Responses in the Lung. AB - Endoplasmic reticulum (ER) stress is evident in the alveolar epithelium of humans and mice with pulmonary fibrosis, but neither the mechanisms causing ER stress nor the contribution of ER stress to fibrosis is understood. A well-recognized adaptive response to ER stress is that affected cells induce lipid synthesis; however, we recently reported that lipid synthesis was downregulated in the alveolar epithelium in pulmonary fibrosis. In the present study, we sought to determine whether lipid synthesis is needed to resolve ER stress and limit fibrotic remodeling in the lung. Pharmacologic and genetic manipulations were performed to assess whether lipid production is required for resolving ER stress and limiting fibrotic responses in cultured alveolar epithelial cells and whole lung tissues. Concentrations of ER stress markers and lipid synthesis enzymes were also measured in control and idiopathic pulmonary fibrosis lung tissues. We found that chemical agents that induce ER stress (tunicamycin or thapsigargin) enhanced lipid production in cultured alveolar epithelial cells and in the mouse lung. Moreover, lipid production was found to be dependent on the enzyme stearoyl coenzyme A desaturase 1, and when pharmacologically inhibited, ER stress persisted and lung fibrosis ensued. Conversely, lipid production was reduced in mouse and human fibrotic lung, despite there being an increase in the magnitude of ER stress. Furthermore, augmenting lipid production effectively reduced ER stress and mitigated fibrotic remodeling in the mouse lung after exposure to silica. Augmenting lipid production reduces ER stress and attenuates fibrotic remodeling in the mouse lung, suggesting that similar approaches might be effective for treating human fibrotic lung diseases. PMID- 29465262 TI - Glecaprevir + pibrentasvir for treatment of hepatitis C. AB - INTRODUCTION: Glecaprevir/pibrentasvir is a fixed-dose combination regimen of a new generation NS3/4A inhibitor and an NS5A inhibitor with potent antiviral activity against all hepatitis C virus (HCV) genotypes. This regimen offers a shorter course of therapy (8 weeks) for selected patients regardless of genotype and has demonstrated high virological efficacy for retreatment of individuals who previously failed an NS5A containing regimen. Glecaprevir and pibrentasvir are minimally excreted by the kidneys; thus this regimen can safely be used in individuals with severe chronic kidney disease (CKD), including those undergoing hemodialysis. Areas covered: This review covers the mechanism of action, pharmacokinetics, clinical applications, efficacy, and safety profile of glecaprevir/pibrentasvir. It also covers key phase 2 and 3 clinical trials that led to licensure of this regimen. Expert opinion: Glecaprevir/pibrentasvir is the latest antiviral regimen licensed in the United States for treatment of HCV infection. Although several other direct-acting antiviral agents (DAAs) are currently available, glecaprevir/pibrentasvir has some unique characteristics that expand treatment options for HCV infection, including patients with comorbidities such as advanced stage CKD or prior treatment failure to antiviral regimens containing other DAAs. PMID- 29465263 TI - Experience with developing antibiotic stewardship programs in Serbia: potential model for other Balkan countries? AB - AIM: Antimicrobial resistance and inappropriate use of antibiotics in children are important issues. Consequently, there is a need to develop comprehensive stewardship programs even in hospitals with limited resources starting with children's hospitals. METHODS: Retrospective observational analysis of antimicrobial utilization and resistance patterns over 5 years in a tertiary care children's hospital in Serbia. RESULTS: Cumulative antimicrobial resistance decreased but was still high, with high cumulative resistance rates among the most widely used antibiotics in the hospital. Total antibiotic use decreased from 2010 to 2014 although there was still high prescribing of reserved antibiotics. CONCLUSION: Concerns with inappropriate use and high resistance rates among some antibiotics used in the hospital are being used to develop guidance on future antibiotic use in this hospital, building on the recently introduced antibiotic stewardship program, as well as encourage other hospitals in Serbia to review their policies. PMID- 29465265 TI - Validation of the DSM-5 Alternative Model Personality Disorder Diagnoses in Turkey, Part 1: LEAD Validity and Reliability of the Personality Functioning Ratings. AB - This study addresses longitudinal, expert, all data (LEAD) validity and reliability of the personality functioning ratings in Turkey, which are essential in assessing Criterion A for the entire DSM-5 alternative model for personality disorders (AMPD) diagnoses. A total of 120 consenting patients recruited at a university psychiatry clinic were rated by individual clinicians with respect to DSM-III-R and AMPD criteria. Subsequently, a LEAD panel consisting of 3 senior clinicians convened to reach a consensus personality disorder diagnosis for each participant. Blind personality functioning ratings of a subgroup of 20 participants by the same set of 4 clinicians were obtained for test-retest reliability investigation. Concordance between the LEAD and AMPD diagnoses was as good as that between the LEAD and DSM-III-R diagnoses (kappas = .68). The personality functioning scores correlated strongly (r > .50) with the sum of specific DSM-III-R diagnoses. Reliability estimates pertaining to the personality functioning scores and resultant AMPD Criterion A decisions were mostly in the good range. In conclusion, DSM-5 alternative model-oriented personality functioning ratings yield total or composite scores that are evidently valid and reliable tools to diagnose general personality disorder and to estimate its global severity. PMID- 29465264 TI - Ibrutinib inhibits free fatty acid metabolism in chronic lymphocytic leukemia. AB - Unlike normal B-cells, and similar to fat cells, chronic lymphocytic leukemia (CLL) cells aberrantly express lipoprotein lipase (LPL), which contributes to free fatty acids (FFAs) metabolism. Here we show that, in CLL cells, the B-cell receptor (BCR) inhibitor ibrutinib reduced LPL mRNA and protein levels and inhibited FFA metabolism in vitro. Likewise, in CLL cells from ibrutinib-treated patients, FFA metabolism was reduced and eventually stopped. Because ibrutinib disrupts CLL cells' ability to use FFAs for energy production, and because various BCR-dependent cellular functions rely on a continuous supply of chemical energy, ibrutinib interrupts several pathways imperative for cellular function in CLL cells. PMID- 29465266 TI - Cardiotoxicity associated with carfilzomib: systematic review and meta-analysis. AB - Carfilzomib is a second-generation proteasome inhibitor (PI) that is approved for patients with relapsed or refractory multiple myeloma (RRMM) who failed >=1 prior lines of therapy. We performed a systematic review of carfilzomib literature with meta-analysis to determine cumulative incidence of cardiotoxicity. After the literature search, we included a total of 29 eligible phase I/II, phase II and phase III clinical trials which used carfilzomib. The cumulative incidence and overall odds ratios (OR) were calculated with random effect model, using 'R' software with metaphor package. A total of 4164 patients with various malignancies were included. The overall estimated cumulative incidence of cardiotoxicity was 8.68% and 4.92%, respectively, for all-grade and high-grade (>= grade 3) toxicity, which seems higher than other PIs. Compared to control group, the odds of developing cardiotoxicity due to carfilzomib was significantly higher with OR of 2.03 (95% CI: 1.19-3.46, p = .010) and 2.04 (95% CI: 1.31-3.17, p = .002) for all-grades and high grades, respectively. Concomitant immunomodulatory agents seem to increase the risk of cardiotoxicity (high-grade cardiotoxicity 6.45% and 4.34% with and without concomitant immunomodulatory agents, respectively (p = .033)). There was no variation in the incidence of cardiotoxicity among newly diagnosed versus RRMM (p = .38), and high versus standard dose carfilzomib (p = .86).

PMID- 29465268 TI - Convergent and discriminant validity of the Immediate Postconcussion Assessment and Cognitive Testing Battery (ImPACT) in young athletes. AB - Sports concussions are recognized as significant injuries among young athletes. Research demonstrates that return-to-play prior to becoming asymptomatic has significant repercussions including sustained cognitive deficits. Many programs have begun to use computerized testing rather than traditional neuropsychological tests to (a) determine baseline performance, (b) track symptoms, and (c) measure symptoms following concussion. Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) is one such tool. The current study examined ImPACT's convergent and discriminant validity by comparing scores from sports-related concussion athletes (SRC) to those from nonconcussed controls (CTL). SRC included 29 athletes, ages 12-16, referred for neuropsychological assessment following sports related concussions. CTL included 25 healthy athletes, ages 12-16, who were concussion-free in the past year. Overall, results showed general support for ImPACT, when used to screen cognition. In fact, all ImPACT domains successfully differentiated between SRC and CTL athletes. Evidence supporting appropriate convergent validity was best for the Visual Memory domain. Further, ImPACT domains demonstrated variable discriminant validity. Overall examination of validity demonstrated that ImPACT has some weaknesses but may have utility in detecting postconcussion cognitive impairment.

AB - A strong foundation in physical conditioning and sport-specific experience, in addition to a bespoke and periodized training and nutrition program, are essential for athlete development. Once these underpinning factors are accounted for, and the athlete reaches a training maturity and competition level where marginal gains determine success, a role may exist for the use of evidence-based performance supplements. However, it is important that any decisions surrounding performance supplements are made in consideration of robust information that suggests the use of a product is safe, legal, and effective. The following review focuses on the current evidence-base for a number of common (and emerging) performance supplements used in sport. The supplements discussed here are separated into three categories based on the level of evidence supporting their use for enhancing sports performance: (1) established (caffeine, creatine, nitrate, beta-alanine, bicarbonate); (2) equivocal (citrate, phosphate, carnitine); and (3) developing. Within each section, the relevant performance type, the potential mechanisms of action, and the most common protocols used in the supplement dosing schedule are summarized.

AB - INTRODUCTION: Multiple myeloma (MM) is generally an incurable hematological malignancy with heterogeneous overall survival rates ranging from a few months to more than 10 years. Survival is especially poor for patients who developed disease that is refractory to immunomodulatory drugs and proteasome inhibitors. Areas covered: This review will discuss the importance of CD38-targeting antibodies for the treatment of MM patients to improve their outcome. Expert commentary: Intense immuno-oncological laboratory research has resulted in the development of functionally active monoclonal antibodies against cell surface markers present on MM cells. In this respect, CD38-targeting antibodies such as daratumumab, MOR202, and isatuximab, have high single agent activity in heavily pretreated MM patients by virtue of their pleiotropic mechanisms of action including Fc-dependent effector mechanisms and immunomodulatory activities. Importantly, CD38-targeting antibodies are well tolerated, with infusion reactions as most frequent adverse event. Altogether, this makes them attractive combination partners with other anti-MM agents. Daratumumab is already approved as monotherapy and in combination with lenalidomide-dexamethasone as well as bortezomib-dexamethasone in pretreated MM patients. Furthermore, results from studies evaluating CD38-targeting antibodies in newly diagnosed MM patients are also promising, indicating that CD38-targeting antibodies will be broadly used in MM, resulting in further improvements in survival.

AB - This retrospective study determined the efficacy of the 'freeze-all' embryo strategy in poor ovarian responders undergoing ovarian stimulation for in vitro fertilization (IVF). A total of 559 poor responders who met Bologna criteria between January 2012 and December 2014 were included in this study: 256 in the fresh embryo transfer group and 303 in the freeze-all group. Vitrification and warming of day 3 embryos were performed using the Cryotop method. The poor responders treated with fresh embryo transfer and those treated with freeze-all strategy showed similar live birth rates per cycle (12.1% vs. 16.2%, p = .172) and per transfer (15.9% vs. 20.9%, p = .182). Multivariate logistic regression analysis showed that maternal age at retrieval (odds ratio, 0.919; 95% confidence interval, 0.865-0.977; p = .006) and number of good-quality embryos transferred (odds ratio, 1.953; 95% confidence interval, 1.346-2.835; p < .001) were significantly associated with the live birth rate. Freeze-all cycle is an acceptable treatment in poor ovarian responders, and it should be suggested by physicians as an alternative to cycle cancelation in case in which a fresh transfer would not be advantageous.

AB - Medication adherence and community living problems were assessed by a telephone intervention for stable outpatients with schizophrenia spectrum disorders. A majority were white males who lived with family members. We conducted a descriptive analysis of data gathered during weekly calls to 87 participants receiving weekly TIPS for nine months. Analysis included traditional atheoretical content analysis, Pearson correlations, and Chi squares. The following themes emerged: mood disturbances and related symptoms, psychotic symptoms, coping problems, medication adherence, and substance cravings. The most frequently reported problems were mood disturbances: depression and anxiety. Forty two percent of Caucasians versus 72.1% of African Americans were prescribed intramuscular (IM) antipsychotic delivery (Chi square = 8.24, df 2, p = 0.016). Our findings regarding racial differences in antipsychotic delivery method warrant further investigation. PMID- 29465274 TI - Intubation Success in Critical Care Transport: A Multicenter Study. AB - INTRODUCTION: Tracheal intubation (TI) is a lifesaving critical care skill. Failed TI attempts, however, can harm patients. Critical care transport (CCT) teams function as the first point of critical care contact for patients being transported to tertiary medical centers for specialized surgical, medical, and trauma care. The Ground and Air Medical qUality in Transport (GAMUT) Quality Improvement Collaborative uses a quality metric database to track CCT quality metric performance, including TI. We sought to describe TI among GAMUT participants with the hypothesis that CCT would perform better than other prehospital TI reports and similarly to hospital TI success. METHODS: The GAMUT Database is a global, voluntary database for tracking consensus quality metric performance among CCT programs performing neonatal, pediatric, and adult transports. The TI-specific quality metrics are "first attempt TI success" and "definitive airway sans hypoxia/hypotension on first attempt (DASH-1A)." The 2015 GAMUT Database was queried and analysis included patient age, program type, and intubation success rate. Analysis included simple statistics and Pearson chi square with Bonferroni-adjusted post hoc z tests (significance = p < 0.05 via two sided testing). RESULTS: Overall, 85,704 patient contacts (neonatal n [%] = 12,664 [14.8%], pediatric n [%] = 28,992 [33.8%], adult n [%] = 44,048 [51.4%]) were included, with 4,036 (4.7%) TI attempts. First attempt TI success was lowest in neonates (59.3%, 617 attempts), better in pediatrics (81.7%, 519 attempts), and best in adults (87%, 2900 attempts), p < 0.001. Adult-focused CCT teams had higher overall first attempt TI success versus pediatric- and neonatal-focused teams (86.9% vs. 63.5%, p < 0.001) and also in pediatric first attempt TI success (86.5% vs. 75.3%, p < 0.001). DASH-1A rates were lower across all patient types (neonatal = 51.9%, pediatric = 74.3%, adult = 79.8%). CONCLUSIONS: CCT TI is not uncommon, and rates of TI and DASH-1A success are higher in adult patients and adult-focused CCT teams. TI success rates are higher in CCT than other prehospital settings, but lower than in-hospital success TI rates. Identifying factors influencing TI success among high performers should influence best practice strategies for TI.

AB - PURPOSE: Physiotherapists, orthotists, and physicians are involved in the prescription of ankle-foot orthoses (AFOs) for children with cerebral palsy (CP); however, little is known about how prescription decisions are made in practice. Therefore, the study objective was to identify current AFO prescription and clinical decision-making practices for children with CP in Canada. METHODS: Focus groups were conducted in five pediatric rehabilitation facilities, with 32 clinicians. Semi-structured interviews focused on the goals and types of AFOs used, referral and follow-up processes, and clinical evaluation measures. Interpretive Description was used as a framework for analysis. Transcribed dialogue was imported into NVivo 11 for data coding and analysis. Three researchers participated in coding to establish categories and themes. RESULTS: Categories included: what is made, how it is used, and factors that either support or challenge outcomes. Strengths and challenges of the current prescription process were discussed, including funding, communication, and technology to enhance clinical evaluation. Throughout the interviews, the theme of prescription as a collaborative, iterative, and individualized process emerged. CONCLUSIONS: Processes, strengths, and challenges associated with AFO prescription in Canada were identified. This is a first step toward the development of guidelines to help clinicians improve AFO prescription for children with CP. PMID- 29465277 TI - What Is the Impact of Targeted Health Education for Mental Health Nurses in the Provision of Physical Health Care? An Integrated Literature Review. AB - Individuals with a severe mental illness have a gap in life expectancy of up to twenty years in comparison to the general population. Nurses who work in mental health services have been identified as best placed to improve the physical health outcomes of individuals with mental illness. The literature identifies a lack of nursing knowledge related to physical health care and the presence of metabolic syndrome which is impeding nurses in providing essential physical health care to patients. An integrated literature review was carried out due to the dearth of research evidence pertaining to the impact of targeted education specifically with psychiatric/mental health nurses in the provision of physical healthcare. A search for literature included the following databases: CINAHL, Medline, PsycINFO, Embase and Web of Science revealed nine studies: seven quantitative, one qualitative and one mixed method. Qualitative synthesis has shed light on the value of targeted education on improving knowledge and skills in providing physical health care that can then be translated into clinical practice. Targeted education in physical healthcare grows psychiatric/mental health nurse's confidence and develops the skills necessary to enable them to screen and monitor and offer range of physical health interventions to individuals with severe mental illness. Accessible summary * The poor physical health outcomes and premature death of individuals with severe mental illness is of growing concern; a contributing factor is a lack of knowledge and confidence amongst psychiatric/mental health nurses to providing physical health screening and intervening in preventable diseases such as cardiovascular disease, stroke cancer, and type 2 diabetes mellitus. * An integrated literature review was used to ascertain if targeted education on physical health care can improve the knowledge base of psychiatric/mental health nurses within physical health care. * Nine studies were critically appraised, and the data reduced using a narrative synthesis that tells a story of the findings from these research studies. * The review found that targeted education with psychiatric/mental health nurses does result in a statistical increase in knowledge This review finds that nurses have not been regularly supported with physical health education to alter existing practices. This lack of knowledge within physical healthcare is hindering psychiatric/mental health nurses to fully engaging in physical health care activities in practice. PMID- 29465278 TI - Differences in Emotion Dysregulation and Symptoms of Depression and Anxiety among Illicit Substance Users and Nonusers. AB - BACKGROUND: Illicit substance users may rely on mind-altering substances to regulate affect, especially when mental health symptoms are present. OBJECTIVES: In light of the prevalence of illicit substance use and symptoms of depression and anxiety among college students, as well as the affect regulation properties of illicit substances, we sought to examine whether differences in emotion dysregulation, depression, anxiety, and stress exist between illicit substance users and non-users. METHODS: At a large Southwestern U.S. university, we examined differences in emotion dysregulation, depression, anxiety, and stress among college students who used illicit substances in the past 30 days (n = 92, 34.5%) and those who did not (n = 175, 65.5%). Data were collected in 2016 using two measures: the Difficulties in Emotion Regulation Scale (DERS; Gratz & Roemer, 2004) and the Depression Anxiety Stress Scales (DASS21; Lovibond & Lovibond, 1995). RESULTS: Results from the Descriptive Discriminate Analysis (DDA) indicated that significant differences existed between the two groups. Anxiety, difficulty clarifying emotions, difficulty employing goal-directed behaviors, and stress accounted the most for the group differences. Conclusion/Importance: Mental health differences between illicit substance users and nonusers exist. Specifically, illicit substance users reported more anxiety, stress, and difficulties with emotion regulation. PMID- 29465279 TI - A Continuous Quality Improvement Airway Program Results in Sustained Increases in Intubation Success. AB - INTRODUCTION: Airway management is a critical skill for air medical providers, including the use of rapid sequence intubation (RSI) medications. Mediocre success rates and a high incidence of complications has challenged air medical providers to improve training and performance improvement efforts to improve clinical performance. OBJECTIVES: The aim of this research was to describe the experience with a novel, integrated advanced airway management program across a large air medical company and explore the impact of the program on improvement in RSI success. METHODS: The Helicopter Advanced Resuscitation Training (HeART) program was implemented across 160 bases in 2015. The HeART program includes a novel conceptual framework based on thorough understanding of physiology, critical thinking using a novel algorithm, difficult airway predictive tools, training in the optimal use of specific airway techniques and devices, and integrated performance improvement efforts to address opportunities for improvement. The C-MAC video/direct laryngoscope and high-fidelity human patient simulation laboratories were implemented during the study period. Chi-square test for trend was used to evaluate for improvements in airway management and RSI success (overall intubation success, first-attempt success, first-attempt success without desaturation) over the 25-month study period following HeART implementation. RESULTS: A total of 5,132 patients underwent RSI during the study period. Improvements in first-attempt intubation success (85% to 95%, p < 0.01) and first-attempt success without desaturation (84% to 94%, p < 0.01) were observed. Overall intubation success increased from 95% to 99% over the study period, but the trend was not statistically significant (p = 0.311). CONCLUSIONS: An integrated advanced airway management program was successful in improving RSI intubation performance in a large air medical company. PMID- 29465280 TI - Friendship and Mental Health. PMID- 29465281 TI - Initial Studies of Validity of the Sensory Processing 3-Dimensions Scale. AB - AIMS: This study examined the validity of a new measure of sensory processing for children, the Sensory Processing 3-Dimensions Scale (SP-3D). The SP-3D is a performance-based measure for children ages three to thirteen years, designed to assess sensory processing abilities, and identify the three patterns of sensory processing disorder (SPD) and related subtypes, including sensory modulation, sensory discrimination, and sensory-based motor disorders. METHODS: Age trends were explored using descriptive statistics and graphing techniques with a sample of children with and without SPD. SP-3D scores were correlated with scores from the Sensory Processing Measure (SPM) to examine criterion-related validity. Discriminant validity was assessed by comparing SP-3D scores from children with and without SPD. RESULTS: Age trends of SP-3D scores supported sensory discrimination, praxis and postural functions as developmental constructs. Several mild to moderate correlations were found between the scores of the SP-3D and the SPM, indicating that the tools are measuring similar constructs, and supporting the SP-3D as a measure of sensory processing. Modulation and Motor Behavior Scores from the SP-3D discriminated typically developing children from those with SPD, while results from subtests measuring sensory discrimination, postural and praxis were mixed regarding capacity for discrimination suggesting revision to several items. CONCLUSION: The study provides preliminary evidence of the SP-3D as a valid measure of sensory processing abilities and dysfunction. Further research regarding the reliability and validity of the SP-3D are needed. PMID- 29465282 TI - Typology of Nightclubs in Sao Paulo, Brazil: Alcohol and Illegal Drug Consumption, Sexual Behavior and Violence in the Venues. AB - BACKGROUND: Nightclubs are venues in which excessive alcohol use and illegal drug consumption occur in addition to other high-risk behaviors, such as violence and sexual risk behaviors. Environmental factors common in nightclubs and the personal characteristics of patrons might increase the risk of these events. To better understand the relationship between these factors, typologies were formulated that clustered nightclubs according to definite profiles to identify differences to be taken into consideration in preventive interventions. OBJECTIVES: The present study aim was to construct a typology of nightclubs in Sao Paulo, Brazil. METHODS: This typology was constructed using mixed methods research through the triangulation of several data sources as follows: 307 hours of ethnographic observation at 31 nightclubs, 8 focus group sessions with nightclub patrons (n = 34) and 30 semi-structured interviews with nightclub employees. Content analysis and qualitative typology were used. RESULTS: Four nightclub types were defined based on four analyzed thematic axes (Intoxicating, Violent, Dancing and Highly Sexualized nightclubs). Excessive alcohol use was detected in almost all of the investigated nightclubs, and drug use was observed in approximately one-third of them. Triangulation of the data revealed a relationship among environmental factors (especially alcohol sales strategies and promotion and the availability of areas for sex) and a more considerable presence of high-risk behaviors. CONCLUSIONS: The study shows that nightclubs are settings in which high-risk behaviors are potentiated by facilitating environmental factors as well as by the lack of laws restricting excessive alcohol use stimulated by the promotion strategies applied at these venues. PMID- 29465283 TI - Augmented reality in dentistry: a current perspective. AB - Augmentation reality technology offers virtual information in addition to that of the real environment and thus opens new possibilities in various fields. The medical applications of augmentation reality are generally concentrated on surgery types, including neurosurgery, laparoscopic surgery and plastic surgery. Augmentation reality technology is also widely used in medical education and training. In dentistry, oral and maxillofacial surgery is the primary area of use, where dental implant placement and orthognathic surgery are the most frequent applications. Recent technological advancements are enabling new applications of restorative dentistry, orthodontics and endodontics. This review briefly summarizes the history, definitions, features, and components of augmented reality technology and discusses its applications and future perspectives in dentistry. PMID- 29465284 TI - Accuracy of Intravenous Infusion Flow Regulators in the Prehospital Environment. AB - OBJECTIVE: To assess the accuracy of multiple Intravenous Infusion Flow Regulators (IIFRs) at infusion rates and hanging heights common to the prehospital setting. METHODS: Five different manufacturer's IIFRs were tested over a range of infusion rates while hanging at heights equivalent to the gurney pole, ambulance ceiling hook, and manufacturer's recommended height (if available). Each IIFR was run over a 15-minute period at each infusion rate and height three times. Drip effluent was collected and measured for comparison of volumes. Intra- and inter-device accuracy at different infusion rates and heights was calculated. RESULTS: All devices deviated from the expected infusion volume regardless of infusion rate or height. There was inter-device variability across all IIFRs with some having reproducible though inaccurate volumes. Volumes were consistently below expected at lower heights and above expected at increased heights. Manufacturer recommended height guidelines provided slight improvements in accuracy. CONCLUSIONS: Significant deviations from expected IIFR volume were observed across all devices, flow rates, and heights in a static, laboratory environment. These findings would lend caution to the use of IIFRs as they could lead to inaccurate medication dosing (both over- or under-dosing) in the prehospital environment. PMID- 29465285 TI - Depressive Symptoms and Suicidal Ideation among Irish Undergraduate College Students. AB - This study examined the prevalence of depressive symptoms and suicidal ideation among 220 first year undergraduate university students in Ireland. Data were collected using the Centre for Epidemiological Studies Depression Scale and the Suicidal Behaviours Questionnaire. Findings indicated that 59% of participants experienced depressive symptoms and 28.5% had suicidal ideation. Financial stress and poor relationships with both parents, increased the odds of experiencing depressive symptoms. Sexual orientation, financial stress, and poor relationships with fathers, increased the odds of experiencing suicidal ideation. Suicidal ideation was also higher in those who had sought help in the past from mental health professionals. Nurses need to be aware of the factors associated with mental ill-health in this population. PMID- 29465286 TI - Genetic association of single nucleotide polymorphisms of FZD4 and BDNF genes with retinopathy of prematurity. AB - BACKGROUND: Retinopathy of prematurity (ROP) is a multifactorial disease occurring in preterm neonates, caused by incorrect development of retinal blood vessels. It has been suggested that, in addition to gestational age, weight, and oxygen supplementation, genetic factors can play a role in the pathogenesis of ROP. METHODS: In the present prospective study, 97 neonates were enrolled based on the gestational age and weight, and genomic DNA from patients diagnosed with ROP and premature newborns without ROP was collected. The DNA sequence of protein coding and 5'and 3' untranslated regions (UTRs) of the frizzled-4 (FZD4) gene and the genotype of the locus rs7934165:G?A (NM_170731.4: c.3 + 10976 C?T) within the brain-derived neurotrophic factor gene (BDNF) were determined. RESULTS: We detected a significant association between rs61749246:C?A (NM_012193.3: c.*2G?T) and ROP in a general genetic model as well as in a multiplicative model and by the Cochran-Armitage test for trend. Moreover, rs61749246 was strongly associated with ROP, requiring surgical intervention. CONCLUSION: We suggest that rs61749246:C?A of the FZD4 gene is likely associated with the development of ROP. It is necessary to confirm this suggestion in larger studies. PMID- 29465288 TI - Origin and Consequences of Necroinflammation. AB - When cells undergo necrotic cell death in either physiological or pathophysiological settings in vivo, they release highly immunogenic intracellular molecules and organelles into the interstitium and thereby represent the strongest known trigger of the immune system. With our increasing understanding of necrosis as a regulated and genetically determined process (RN, regulated necrosis), necrosis and necroinflammation can be pharmacologically prevented. This review discusses our current knowledge about signaling pathways of necrotic cell death as the origin of necroinflammation. Multiple pathways of RN such as necroptosis, ferroptosis, and pyroptosis have been evolutionary conserved most likely because of their differences in immunogenicity. As the consequence of necrosis, however, all necrotic cells release damage associated molecular patterns (DAMPs) that have been extensively investigated over the last two decades. Analysis of necroinflammation allows characterizing specific signatures for each particular pathway of cell death. While all RN-pathways share the release of DAMPs in general, most of them actively regulate the immune system by the additional expression and/or maturation of either pro- or anti inflammatory cytokines/chemokines. In addition, DAMPs have been demonstrated to modulate the process of regeneration. For the purpose of better understanding of necroinflammation, we introduce a novel classification of DAMPs in this review to help detect the relative contribution of each RN-pathway to certain physiological and pathophysiological conditions. PMID- 29465287 TI - The exoribonuclease Xrn1 is a post-transcriptional negative regulator of autophagy. AB - Macroautophagy/autophagy is a conserved catabolic process that promotes survival during stress. Autophagic dysfunction is associated with pathologies such as cancer and neurodegenerative diseases. Thus, autophagy must be strictly modulated at multiple levels (transcriptional, post-transcriptional, translational and post translational) to prevent deregulation. Relatively little is known about the post transcriptional control of autophagy. Here we report that the exoribonuclease Xrn1/XRN1 functions as a negative autophagy factor in the yeast Saccharomyces cerevisiae and in mammalian cells. In yeast, chromosomal deletion of XRN1 enhances autophagy and the frequency of autophagosome formation. Loss of Xrn1 results in the upregulation of autophagy-related (ATG) transcripts under nutrient replete conditions, and this effect is dependent on the ribonuclease activity of Xrn1. Xrn1 expression is regulated by the yeast transcription factor Ash1 in rich conditions. In mammalian cells, siRNA depletion of XRN1 enhances autophagy and the replication of 2 picornaviruses. This work provides insight into the role of the RNA decay factor Xrn1/XRN1 as a post-transcriptional regulator of autophagy. PMID- 29465290 TI - Global, integrated analysis of methylomes and transcriptomes from laser capture microdissected bronchial and alveolar cells in human lung. AB - Gene regulatory analysis of highly diverse human tissues in vivo is essentially constrained by the challenge of performing genome-wide, integrated epigenetic and transcriptomic analysis in small selected groups of specific cell types. Here we performed genome-wide bisulfite sequencing and RNA-seq from the same small groups of bronchial and alveolar cells isolated by laser capture microdissection from flash-frozen lung tissue of 12 donors and their peripheral blood T cells. Methylation and transcriptome patterns differed between alveolar and bronchial cells, while each of these epithelia showed more differences from mesodermally derived T cells. Differentially methylated regions (DMRs) between alveolar and bronchial cells tended to locate at regulatory regions affecting promoters of 4,350 genes. A large number of pathways enriched for these DMRs including GTPase signal transduction, cell death, and skeletal muscle. Similar patterns of transcriptome differences were observed: 4,108 differentially expressed genes (DEGs) enriched in GTPase signal transduction, inflammation, cilium assembly, and others. Prioritizing using DMR-DEG regulatory network, we highlighted genes, e.g., ETS1, PPARG, and RXRG, at prominent alveolar vs. bronchial cell discriminant nodes. Our results show that multi-omic analysis of small, highly specific cells is feasible and yields unique physiologic loci distinguishing human lung cell types in situ. PMID- 29465291 TI - Men's hopes, fears and challenges in engagement in perinatal health and the prevention of mother-to-child transmission of HIV in rural Kenya. AB - Male involvement in antenatal care has been shown to improve health outcomes for women and infants. However, little is known about how best to encourage male partners to support essential perinatal health activities. We explored men's perceptions of facilitators and barriers to involvement in antenatal care and HIV prevention including fears, hopes and challenges. Forty in-depth interviews were conducted with the male partners of HIV-positive and HIV-negative pregnant women in southwest Kenya. Most male partners believed engaging in pregnancy health related activities was beneficial for keeping families healthy. However, thematic analysis revealed several obstacles that hindered participation. Poor couple relationship dynamics seemed negatively to influence male engagement. Some men were apprehensive that clinic staff might force them to test for HIV and disclose the results; if HIV-positive, men feared being labelled as 'victimisers' in situations of serodiscordancy, and described fears of abandonment by their wives. Some men avoided accompanying their wives, citing local culture as rationale for avoiding the 'effeminate' act of antenatal care attendance. Amidst these obstacles, some men chose to use their partners' HIV status as proxy for their own. Findings suggest that improving male engagement in essential maternal and child health-related activities will require addressing both structural and interpersonal barriers. PMID- 29465292 TI - An unusual case of sudden cardiac death during sexual intercourse. AB - The most common cause of sudden death during sexual intercourse in adults is heart disease, and it is usually the male, whereas the death of the woman is unusual. Generally, in these cases, death occurs as a result of cardiovascular disease. The authors report an unusual case of the sudden death of a young woman during sexual intercourse. The post-mortem investigations (autopsy, cardiac nuclear magnetic resonance and cardiac histology) demonstrated a previously undiagnosed arrhythmogenic right ventricular cardiomyopathy. The terminal cause of death was a malignant arrhythmia from arrhythmogenic right ventricular cardiomyopathy. This is the first report of a case in which sexual activity can be regarded as the triggering factor combined with cardiac disease to the woman's death. PMID- 29465293 TI - Effectiveness of a physical activity program on weight, physical fitness, occupational stress, job satisfaction and quality of life of overweight employees in high-tech industries: a randomized controlled study. AB - INTRODUCTION: This study aimed to examine the effectiveness of a physical activity (PA) program on weight control, physical fitness, occupational stress, job satisfaction and quality of life of overweight and sedentary employees in high-tech industries. METHODS: Participants in the intervention group (n = 37) were instructed to carry out a PA program at moderate intensity for 60 min/session, 3 sessions/week for 12 weeks. Those in the control group (n = 38) received no PA program and were asked to continue their routine lifestyle. Evaluations were performed at baseline and at the end of the intervention. Results of structured questionnaires and blood biochemistry tests and evaluations of physical fitness were analyzed. RESULTS: The PA program effectively reduced the number of risk factors for metabolic syndrome and body fat percentage, and improved physical fitness such as flexibility, muscular strength and endurance and cardiorespiratory endurance. The intervention also significantly decreased levels of serum triglyceride, total cholesterol and low-density lipoprotein cholesterol. Significant positive effects on work control, interpersonal relationships at work, global job satisfaction and quality of life were also demonstrated. CONCLUSION: This study showed that a PA program can be helpful in improving physical, physiological and psychological outcomes for overweight and sedentary employees in high-tech industries. PMID- 29465294 TI - Occupational health risk assessment of volatile organic compounds emitted from the coke production unit of a steel plant. AB - In this study, cancer and non-cancer risks of exposure to volatile organic compounds in the coke production unit of a steel plant were evaluated. To determine individual exposure to benzene, toluene, xylene and ethylbenzene, personal samples were taken from the breathing zone of workers according to National Institute for Occupational Safety and Health (NIOSH) method 1501. Cancer and non-cancer risk assessment was performed, using US Environmental Protection Agency (US EPA) methods. Samples analysis showed that the concentration of benzene in the energy and biochemistry and the benzol refinement sections was higher than occupational exposure limits. The cancer risk for benzene in all sections was significantly higher than allowable limit; the non-cancer risk for benzene in all sections and toluene in the benzol refinement section was also higher than 1.0. In conclusion, the current control measures are not sufficient and should be improved for efficient control of occupational exposures. PMID- 29465295 TI - Predicting complicated outcomes in spinal cord injury patients with urinary tract infection: Development and internal validation of a risk model. AB - CONTEXT/OBJECTIVE: Patients with chronic SCI hospitalized for UTI can have significant morbidity. It is unclear whether SIRS criteria, SOFA score, or quick SOFA score can be used to predict complicated outcome. DESIGN: Retrospective cohort study. A risk prediction model was developed and internally validated using bootstrapping methodology. SETTING: Urban, academic hospital in St. Louis, Missouri. PARTICIPANTS: 402 hospitalizations for UTI between October 1, 2010 and September 30, 2015, arising from 164 patients with chronic SCI, were included in the final analysis. Outcome/measures: An a priori composite complicated outcome defined as: 30-day hospital mortality, length of hospital stay >4 days, intensive care unit (ICU) admission, and hospital revisit within 30 days of discharge. RESULTS: Mean age of patients was 46.4 +/- 12.3 years; 83.6% of patient-visits involved males. The primary outcome occurred in 278 (69.2%) hospitalizations. In multivariate analysis, male sex was protective (odds ratio [OR], 0.43; 95% confidence interval [CI], 0.18-0.99; P = 0.048) while Gram-positive urine culture (OR 3.07; 95% CI, 1.05-9.01; P = 0.041), urine culture with no growth (OR, 1.69; 95% CI, 1.02-2.80; P = 0.041), and greater SOFA score (for one-point increments, OR, 1.41; 95% CI, 1.18-1.69; P < 0.001) were predictive for complicated outcome. SIRS criteria and qSOFA score were not associated with complicated outcome. Our risk prediction model demonstrated good overall performance (Brier score, 0.19), fair discriminatory power (c-index, 0.72), and good calibration during internal validation. CONCLUSION: Clinical variables present on hospital admission with UTI may help identify SCI patients at risk for complicated outcomes and inform future clinical decision-making. PMID- 29465296 TI - Airlift bioreactor system for simultaneous removal of hydrogen sulfide and ammonia from synthetic and actual waste gases. AB - The effectiveness of an airlift reactor system in simultaneously removing hydrogen sulfide (H2S) and ammonia (NH3) from synthetic and actual waste gases was investigated. The effects of various parameters, including the ratio of inoculum dilution, the gas concentration, the gas retention time, catalyst addition, the bubble size, and light intensity, on H2S and NH3 removal were investigated. The results revealed that optimal gas removal could be achieved by employing an activated inoculum, using a small bubble stone, applying reinforced fluorescent light, adding Fe2O3 catalysts, and applying a gas retention time of 20 s. The shock loading did not substantially affect the removal efficiency of the airlift bioreactor. Moreover, more than 98.5% of H2S and 99.6% of NH3 were removed in treating actual waste gases. Fifteen bands or species were observed in a profile from denaturing gradient gel electrophoresis during waste gas treatment. Phylogenetic analysis revealed the phylum Proteobacteria to be predominant. Six bacterial strains were consistently present during the entire operating period; however, only Rhodobacter capsulatus, Rhodopseudomonas palustris, and Arthrobacter oxydans were relatively abundant in the system. The photosynthetic bacteria R. capsulatus and R. palustris were responsible for H2S oxidation, especially when the reinforced fluorescent light was used. The heterotrophic nitrifier A. oxydans was responsible for NH3 oxidation. To our knowledge, this is the first report on simultaneous H2S and NH3 removal using an airlift bioreactor system. It clearly demonstrates the effectiveness of the system in treating actual waste gases containing H2S and NH3.

AB - In this work, the effect of the improvement carried out at a large-scale wastewater treatment plant (WWTP) was evaluated, by means of modelling works, with the aim to determine the influence of the modernization over the process performance. After modernization, the energy consumption due to the aeration decreased about a 20% maintaining the effluent quality. In order to double-check the good effluent quality, modelling works were carried out at the full-scale plant. After calibration, the model was applied to the upgraded full-scale plant obtaining deviations lower than 10%. Then, the performance of the main biochemical processes was evaluated in terms of oxygen uptake rate (OUR), ammonia uptake rate (AUR), and chemical oxygen demand (COD) consumption. The rate of the main processes depending on the aeration, that is OUR and AUR, were about 22 gO2/(kg VSS.h) and 2.9 gN/(kg VSS.h), respectively. PMID- 29465298 TI - The determination of the validity of an application-based knee-training device. AB - The goals of knee rehabilitation are to improve range of motion and muscle status. The aim of the study was to investigate accuracy and reproducibility of a newly designed knee-training device (KT) under standardized laboratory conditions. Two application-based software programs, one to measure maximum force and the other intended to improve users' coordination were developed to be used on a tablet during exercises, wirelessly connected to KT placed under the popliteal fossa. KT was loaded for 20 intervals of 15 seconds (s) ranging between 0-350 Newton (N) each. The interval of times was chosen to be enough to take right measurement for accurate results. In addition, a 300-s continuous measurement was undertaken. The pressure readings were developed through a servo hydraulic system and used as reference values. KT results were compared with the reference values to assess its accuracy. In addition, KT was tested on a force measuring platform in a close to reality measurement. Based on Bland-Altman plots, the mean difference between KT and material testing machine was -0.63 N (0.4%), between KT and force-measuring platform was -0.11 N (0.7%), which proves the accuracy of its result. Laboratory experiments confirm that KT delivers precise and reproducible values, which provide base for clinical trials.

AB - BACKGROUND: Reports indicate a geographic effect of socioeconomic inequalities on the occurrence of opioid-related fatal overdoses. This study aims to (1) estimate the rates of opioid-related overdoses, (2) estimate the association of benzodiazepine co-ingestion with opioid-related deaths, (3) estimate associations between socioeconomic indicators and opioid-related deaths, and (4) map the distribution of fatal overdoses, in Orange County (OC), California. METHODS: An ecologic study was conducted of all opioid- related deaths (1205 total) from 2010 to 2014 obtained from the OC Coroner Division database (1065 OC residents, 55 nonresidents, 85 OC homeless) (analyzed 2016-2017). Rates of opioid overdose, benzodiazepine co-ingestion prevalence, and associations with socioeconomic status (SES; education, poverty, median income) using ZIP code analysis in the residential and homeless communities were calculated. RESULTS: Of 1205 deaths, 904 involved prescription-type opioids, 223 involved heroin, 39 involved both, and 39 not stated; 973 were classified unintentional overdoses, 180 suicides, and 52 undetermined; 49% of cases involved benzodiazepines. Prescription-type opioid and heroin death rates for residents were 5.4/ 100,000 person-years (95% confidence interval [CI]: 5.0-5.8) and 1.2/100,000 person-years (95% CI: 1.0 1.4), respectively. Males, age group 45-54, and Caucasian race had the highest rate (13.6/100,000) of opioid mortality. The highest death rates were seen in homeless adults, at 136/100,000 person-years for prescription-type opioids (95% CI: 99.0-185.5) and 156/100,000 person-years for heroin (95% CI: 116.8-209.5). CONCLUSIONS: The burden of prescription-type opioid-related deaths in OC affects all demographics and levels of SES; there is a disproportionately high rate of opioid-related deaths in the OC homeless population. PMID- 29465302 TI - Merits and complexities of modeling multiple sclerosis in non-human primates: implications for drug discovery. AB - INTRODUCTION: The translation of scientific discoveries made in animal models into effective treatments for patients often fails, indicating that currently used disease models in preclinical research are insufficiently predictive for clinical success. An often-used model in the preclinical research of autoimmune neurological diseases, multiple sclerosis in particular, is experimental autoimmune encephalomyelitis (EAE). Most EAE models are based on genetically susceptible inbred/SPF mouse strains used at adolescent age (10-12 weeks), which lack exposure to genetic and microbial factors which shape the human immune system. Areas covered: Herein, the authors ask whether an EAE model in adult non human primates from an outbred conventionally-housed colony could help bridge the translational gap between rodent EAE models and MS patients. Particularly, the authors discuss a novel and translationally relevant EAE model in common marmosets (Callithrix jacchus) that shares remarkable pathological similarity with MS. Expert opinion: The MS-like pathology in this model is caused by the interaction of effector memory T cells with B cells infected with the gamma1 herpesvirus (CalHV3), both present in the pathogen-educated marmoset immune repertoire. The authors postulate that depletion of only the small subset (<0.05%) of CalHV3-infected B cells may be sufficient to limit chronic inflammatory demyelination. PMID- 29465303 TI - Morphologic and morphometric study on microvasculature of developing mouse kidneys. AB - A proper morphogenesis of the renal microvasculature is crucial not only for fulfilling the renal function but also to slow down the progression of chronic kidney disease in adulthood. However, the current description of the developing microvasculature is incomplete. The present study investigated the morphogenesis and volume densities of the renal microvasculature using computer-assisted tubular tracing, immunohistochemistry for CD34, and unbiased stereology. The earliest glomerular capillaries were observed at the lower cleft of the S-shaped nephrons, as simple loops connecting the afferent and efferent arterioles. In parallel with this, the peritubular capillaries were established. Noticeably, from early nephrogenesis on, the efferent arterioles of the early-formed glomeruli ran in close proximity to their own thick ascending limbs. In addition, the ascending vasa recta arising from the arcuate or interlobular veins also ran in close proximity to the thick descending limb. Thus, the tubules and vessels formed the typical countercurrent relation in the medulla. No loop bends were observed between descending and ascending vasa recta. The volume density of the cortical and medullary peritubular capillary increased 3.3- and 2.6-fold, respectively, from 2.34 (0.13) and 7.03 (0.09)% [means (SD)] at embryonic day 14.5 (E14.5) to 7.71 (0.44) and 18.27 (1.17)% at postnatal day 40 (P40). In contrast, the volume density of glomeruli changed only slightly during kidney development, from 4.61 (0.47)% at E14.5 to 6.07 (0.2)% at P7 to 4.19 (0.47)% at P40. These results reflect that the growth and formation of the renal microvasculature closely correspond to functional development of the tubules. PMID- 29465304 TI - A MAPP Network study: overexpression of tumor necrosis factor-alpha in mouse urothelium mimics interstitial cystitis. AB - Interstitial cystitis/bladder pain syndrome is a chronic bladder condition associated with pain and voiding dysfunction that is often regarded as a neurogenic cystitis. Patient symptoms are correlated with the presence of urothelial lesions. We previously characterized a murine neurogenic cystitis model that recapitulates mast cell accumulation and urothelial lesions, and these events were dependent on TNF. To further explore the role of TNF in bladder inflammation and function, we generated a transgenic mouse model with chronic TNF overexpression in urothelium under the control of the uroplakin II (UPII) promoter. Transgenic mouse lines were maintained by backcross onto wild-type C57BL/6J mice and evaluated for pelvic tactile allodynia as a measure of visceral pain, urinary function, and urothelial lesions. TNF mRNA and protein were expressed at greater levels in bladders of UPII-TNF mice than in those of wild type mice. UPII-TNF mice showed significantly increased urinary frequency and decreased void volume. UPII-TNF mice had increased urothelial apoptosis and loss of urothelial integrity consistent with urothelial lesions. Overexpression of TNF was also associated with pelvic tactile allodynia. Consistent with these findings, UPII-TNF mice exhibited increased bladder afferent activity in response to stretch ex vivo. In summary, UPII-TNF mice display significant pelvic pain, voiding dysfunction, urothelial lesions, and sensory input. Thus UPII-TNF mice are a model for characterizing mechanisms of interstitial cystitis symptoms and evaluating therapies. PMID- 29465305 TI - Glomerular hyperpermeability after acute unilateral ureteral obstruction: effects of Tempol, NOS, RhoA, and Rac-1 inhibition. AB - It is well known that proteinuria following urinary tract obstruction is mainly of a tubular nature. However, it is unknown whether there are also changes in glomerular permeability. In this study, we compared glomerular sieving coefficients (theta) of polydisperse fluorescein isothiocyanate (FITC)-Ficoll 70/400 following a 120- or 180-min unilateral ureteral obstruction (UUO) in anesthetized Sprague-Dawley rats. Samples were collected from the obstructed kidney at 5, 15, and 30 min postrelease and analyzed by means of high-pressure size-exclusion chromatography. After 120-min UUO, mean theta for Ficoll70A was increased ( P < 0.01) from 2.2 +/- 0.5 * 10-5 (baseline) to 10.6 +/- 10 * 10-5 15 min postrelease (highest value). After 180-min UUO, mean theta for Ficoll70A was further increased ( P < 0.001) from 1.4 +/- 0.5 * 10-5 (baseline) to 40 +/- 10 * 10-5 at 5 min postrelease (highest value). Administration of a reactive oxygen species (ROS) scavenger (Tempol; 1 mg.kg-1.min-1) partly abrogated the permeability effects following 120-min UUO but not after 180 min. Moreover, administration of the RhoA kinase inhibitor Y-27632, the nitric oxide synthase inhibitor NG-nitro-l-arginine methyl ester, or Rac-1 inhibition did not ameliorate glomerular hyperpermeability following 180-min UUO. We show, for the first time, that acute UUO results in marked elevations in glomerular permeability. In addition, our data suggest a time-dependent pathophysiology of UUO-induced hyperpermeability, where reactive oxygen species generation may play an important role in the early stages. PMID- 29465306 TI - Sex dimorphism in the distribution of adipose tissue and its influence on proinflammatory adipokines and cardiometabolic profiles in motor complete spinal cord injury. AB - OBJECTIVE: We aimed to examine the influence of sex on the distribution of adipose tissue, as well as proinflammatory adipokine and cardiometabolic profiles, in chronic motor complete spinal cord injury (SCI). DESIGN: Cross sectional and correlational study. SETTING: Academic rehabilitation hospital. PARTICIPANTS: Forty-seven individuals with chronic motor complete SCI classified according to sex (males: age 44.0 +/- 10.9 y, body mass index (BMI) 27.2 +/- 5.8, level of injury (LOI) C4 - L1; females: 42.0 +/- 13.5 y, BMI 27.8 +/- 6.6, LOI C4 - T11). INTERVENTION: Not applicable. OUTCOME MEASURES: Visceral (VAT), subcutaneous (SAT), and total trunk (TTAT) adipose tissue volumes were assessed utilizing magnetic resonance imaging and a VAT:SAT ratio was calculated. Proinflammatory adipokines (tumor neurosis factor-alpha, interleukin-6, plasminogen activator inhibitor-1, thrombin-activatable fibrinolysis inhibitor, and high sensitivity c-reactive protein) and cardiovascular, carbohydrate, and lipid profiles were evaluated according to standard techniques. RESULTS: VAT and VAT:SAT ratio were significantly greater in male participates with SCI (P <= 0.002), while SAT volume was significantly greater in female participants with SCI (P = 0.001). No difference was noted in TTAT between groups (P = 0.341). Male participants with SCI demonstrated lower high-density lipoprotein-cholesterol (HDLC) profiles and an elevated total cholesterol to HDLC ratio (P <= 0.003) compared with females. No other significant differences were found between groups concerning cardiometabolic profiles or proinflammatory adipokines; however, males exhibited poorer profiles overall. Proinflammatory adipokines significantly correlated with adipose tissue depots by sex (P < 0.05). CONCLUSION: The results show that sex influences the distribution of adipose tissue, and may influence proinflammatory and cardiometabolic profiles following SCI. The findings of this study highlight the need for further research with dietary modification and exercise to decrease health risks. PMID- 29465307 TI - Sensory sensitivity and posttraumatic stress disorder in blast exposed veterans with mild traumatic brain injury. AB - The purpose of this study was to examine the unique contribution of posttraumatic stress disorder (PTSD) symptoms on sensory sensitivity following mild traumatic brain injury (mTBI) in an Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF) Veteran sample. We hypothesized that the effect of PTSD on noise and light sensitivity following mTBI would be largely driven by PTSD-related hyperarousal symptoms. We compared the relationships between PTSD, noise sensitivity, and light sensitivity of 49 OEF/OIF Veterans with mTBI to that of 23 OEF/OIF Veterans without mTBI. Results suggest that intrusive experiences were significantly related to noise sensitivity in the mTBI group, while light sensitivity was significantly associated with avoidance. Hyperarousal symptoms significantly accounted for noise sensitivity in the no-blast, non-TBI group, whereas PTSD did not affect light sensitivity in this group. These data suggest that PTSD symptoms may uniquely influence the experience of noise and light sensitivity. As such, treatment targeting specific PTSD symptoms may yield clinically significant improvement in sensory sensitivity.

PMID- 29465308 TI - CLL2-BXX Phase II trials: sequential, targeted treatment for eradication of minimal residual disease in chronic lymphocytic leukemia. AB - AIM: Four Phase II trials (clinical trials numbers: NCT02345863, NCT02401503, NCT02445131 and NCT02689141) evaluate a different combination of targeted agents in an all-comer population of approximately 60 patients with chronic lymphocytic leukemia irrespective of prior treatment, physical fitness and genetic risk factors. Patients with a higher tumor load start with a debulking treatment with bendamustine. The subsequent induction and maintenance treatment with an anti CD20 antibody (obinutuzumab or ofatumumab) and a targeted oral agent (ibrutinib, idelalisib or venetoclax) are continued until achievement of a complete response and minimal residual disease negativity. CONCLUSION: This strategy represents a new era of chronic lymphocytic leukemia therapy where chemotherapy is increasingly replaced by targeted agents and treatment duration is tailored to the patient's individual tumor load and response. PMID- 29465310 TI - Dietary starch breakdown product sensing mobilizes and apically activates alpha glucosidases in small intestinal enterocytes. AB - Dietary starch is finally converted to glucose for absorption by the small intestine mucosal alpha-glucosidases (sucrase-isomaltase [SI] and maltase glucoamylase), and control of this process has health implications. Here, the molecular mechanisms were analyzed associated with starch-triggered maturation and transport of SI. Biosynthetic pulse-chase in Caco-2 cells revealed that the high MW SI species (265 kDa) induced by maltose (an alpha-amylase starch digestion product) had a higher rate of early trafficking and maturation compared with a glucose-induced SI (245 kDa). The maltose-induced SI was found to have higher affinity to lipid rafts, which are associated with enhanced targeting to the apical membrane and higher activity. Accordingly, in situ maltose-hydrolyzing action was enhanced in the maltose-treated cells. Thus, starch digestion products at the luminal surface of small intestinal enterocytes are sensed and accelerate the intracellular processing of SI to enhance starch digestion capacity in the intestinal lumen.-Chegeni, M., Amiri, M., Nichols, B. L., Naim, H. Y., Hamaker, B. R. Dietary starch breakdown product sensing mobilizes and apically activates alpha-glucosidases in small intestinal enterocytes. PMID- 29465311 TI - p32 regulates ER stress and lipid homeostasis by down-regulating GCS1 expression. AB - Sustained endoplasmic reticulum (ER) stress plays a major role in the development of many metabolic diseases, including cardiovascular disease, nonalcoholic fatty liver disease, insulin resistance, obesity, and diabetes. p32 is a multicompartmental protein involved in the regulation of oxidative phosphorylation and glucose oxidation. p32 ablation is associated with resistance to age-associated and diet-induced obesity through a mechanism that remains largely unknown. Here, we show that p32 promotes lipid biosynthesis by modulating fatty acid-induced ER stress. We found that p32 interacts with endoplasmic reticulum-anchored enzyme mannosyl-oligosaccharide glucosidase I (GCS1), an ER lumen-anchored glucosidase that is essential for the processing of N-linked glycoproteins, and reduces GCS1 in a lysosome-dependent manner. We demonstrate that increased GCS1 expression alleviates fatty acid-induced ER stress and is critical for suppressing ER stress-associated lipogenic gene activation, as demonstrated by the down-regulation of Srebp1, Fasn, and Acc. Consistently, suppression of p32 leads to increased GCS1 expression and alleviates fatty acid induced ER stress, resulting in reduced lipid accumulation. Thus, p32 and GCS1 are regulators of ER function and lipid homeostasis and are potential therapeutic targets for the treatment of obesity and diabetes.-Liu, Y., Leslie, P. L., Jin, A., Itahana, K., Graves, L. M., Zhang, Y. p32 regulates ER stress and lipid homeostasis by down-regulating GCS1 expression. PMID- 29465312 TI - Identification of a TGF-beta-miR-195 positive feedback loop in hepatocytes and its deregulation in hepatoma cells. AB - Resistance to TGF-beta-induced growth repression is prevalent in various cancer cells, but the underlying mechanisms remain unclear. In this study, we showed that activation of TGF-beta signaling caused Sma- and Mad-related family (Smad) 2 and Smad3 to bind directly to the promoter region of miR-195, and then activated miR-195 transcription in normal hepatocytes. Conversely, miR-195 inhibited the expression of Smad7 by binding to its 3'-UTR, thereby strengthening TGF-beta-Smad signaling. These data identify a novel TGF-beta-miR-195 positive regulatory circuitry in normal hepatocytes. Further investigation revealed that HDAC1, a histone deacetylase that was abnormally overexpressed in hepatocellular carcinoma, could bind to the miR-195 promoter via Smad3 and cause hypoacetylation in the histones associated with the miR-195 promoter in hepatoma cells. This resulted in transcriptional repression of miR-195 and, subsequently, disruption of the TGF-beta-miR-195 regulatory loop and evasion of TGF-beta-mediated growth inhibition. Moreover, silencing HDAC1 in hepatoma cells restored TGF-beta mediated growth suppression, but this effect was attenuated if miR-195 expression decreased. These findings suggest that HDAC1-induced miR-195 down-regulation is an important mechanism for tumor cells to resist the cytostatic activity of TGF beta, and highlight the importance of TGF-beta-Smad2/3-miR-195-Smad7 circuitry in preventing uncontrolled cell proliferation.-Wang, R., Fu, T., You, K., Li, S., Zhao, N., Yang, J., Zhuang, S.-M. Identification of a TGF-beta-miR-195 positive feedback loop in hepatocytes and its deregulation in hepatoma cells. PMID- 29465313 TI - CD5L is upregulated in hepatocellular carcinoma and promotes liver cancer cell proliferation and antiapoptotic responses by binding to HSPA5 (GRP78). AB - CD5-like (CD5L) is a soluble scavenger cysteine-rich protein that modulates inflammatory responses. We studied the involvement of CD5L in liver cancer. Immunohistochemistry (IHC) of CD5L in 60 hepatocellular carcinomas and 34 adjacent nontumor livers, showed that CD5L staining was higher in tumor than in nontumor tissue (Mann-Whitney test; P = 0.0039). High CD5L correlated with elevated proliferation (Ki67, linear regression; P < 0.0001) and lower patient event-free survival (log-rank; P = 0.0185). Accordingly, CD5L expression was detected in the liver cancer cell lines Huh7, HepG2, and SNU-398. In vitro technologies using these cell lines, including small interfering RNA (siRNA) and cDNA transfection, showed that CD5L promoted colony formation and cell proliferation and protected against cisplatin-induced apoptosis. To find a molecular explanation for these roles, novel CD5L-interacting protein ligands in liver cancer cells were identified by immunoprecipitation followed by mass spectrometry. Among these, the molecular chaperone of the unfolded protein response (UPR), heat shock protein (HSP)-A5, was selected for validation. The interaction was confirmed by confocal microscopy in the Huh7 and HepG2 cell lines. Furthermore, functional experiments revealed that CD5L activates the UPR and autophagy mechanisms in Huh7 cells, thereby providing a novel molecular link between the UPR and autophagy in liver cancer.-Aran, G., Sanjurjo, L., Barcena, C., Simon-Coma, M., Tellez, E., Vazquez-Vitali, M., Garrido, M., Guerra, L., Diaz, E., Ojanguren, I., Elortza, F., Planas, R., Sala, M., Armengol, C., Sarrias, M.-R.

PMID- 29465314 TI - Endogenously generated arachidonate-derived ligands for TRPV1 induce cardiac protection in sepsis. AB - The severity of cardiac dysfunction predicts mortality in sepsis. Activation of transient receptor potential vanilloid receptor type (TRPV)-1, a predominantly neuronal nonselective cation channel, has been shown to improve outcome in sepsis and endotoxemia. However, the role of TRPV1 and the identity of its endogenous ligands in the cardiac dysfunction caused by sepsis and endotoxemia are unknown. Using TRPV1-/- and TRPV1+/+ mice, we showed that endogenous activation of cardiac TRPV1 during sepsis is key to limiting the ensuing cardiac dysfunction. Use of liquid chromatography-tandem mass spectrometry lipid analysis and selective inhibitors of arachidonic metabolism suggest that the arachidonate-derived TRPV1 activator, 20-hydroxyeicosateraenoic acid (20-HETE), underlies a substantial component of TRPV1-mediated cardioprotection in sepsis. Moreover, using selective antagonists for neuropeptide receptors, we show that this effect of TRPV1 relates to the activity of neuronally released cardiac calcitonin gene-related peptide (CGRP) and that, accordingly, administration of CGRP can rescue cardiac dysfunction in severe endotoxemia. In sum activation of TRPV1 by 20-HETE leads to the release of CGRP, which protects the heart against the cardiac dysfunction in endotoxemia and identifies both TRPV1 and CGRP receptors as potential therapeutic targets in endotoxemia.-Chen, J., Hamers, A.

PMID- 29465315 TI - Ginsenoside Rh2 inhibits vascular endothelial growth factor-induced corneal neovascularization. AB - VEGF-induced neovascularization plays a pivotal role in corneal neovascularization (CoNV). The current study investigated the potential effect of ginsenoside Rh2 (GRh2) on neovascularization. In HUVECs, pretreatment with GRh2 largely attenuated VEGF-induced cell proliferation, migration, and vessel-like tube formation in vitro. At the molecular level, GRh2 disrupted VEGF-induced VEGF receptor 2 (VEGFR2)-Grb-2-associated binder 1 (Gab1) association in HUVECs, causing inactivation of downstream AKT and ERK signaling. Gab1 knockdown (by targeted short hairpin RNA) similarly inhibited HUVEC proliferation and migration. Notably, GRh2 was ineffective against VEGF in Gab1-silenced HUVECs. In a mouse cornea alkali burn model, GRh2 eyedrops inhibited alkali-induced neovascularization and inflammatory cell infiltrations in the cornea. Furthermore, alkali-induced corneal expression of mRNAs/long noncoding RNAs in cornea were largely attenuated by GRh2. Overall, GRh2 inhibits VEGF-induced angiogenic effect via inhibiting VEGFR2-Gab1 signaling in vitro. It also alleviates angiogenic and inflammatory responses in alkali burn-treated mouse corneas.-Zhang, X.-P., Li, K.-R., Yu, Q., Yao, M.-D., Ge, H.-M., Li, X.-M., Jiang, Q., Yao, J., Cao, C.

AB - PURPOSE/OBJECTIVES: Overall non-melanoma head and neck skin cancer has a good prognosis; however, rarely patients have an aggressive variant which results in orbital invasion via perineural spread or direct extension. Despite these consequences, there are limited published studies defining this clinical entity. The main objectives of the current study are to describe orbital invasion patterns of non-melanoma head and neck skin cancers and their impact on survival. METHODS: Retrospective case series from a tertiary-care, academic institution performed between 2004 and 2014. Demographic and tumour characteristics are reported as well as patterns of orbital invasion, types of treatments received, and survival outcomes. RESULTS: There were 17 consecutive patients with non melanoma skin cancer and orbital invasion who met inclusion criteria. Average age at orbital invasion diagnosis was 70.8 years old. 76% were male. Mean follow-up time was 28.5 months. Of these patients, 71% had squamous cell carcinoma and 29% had basal cell carcinoma. Brow (41%) was the most common primary sub-site followed by cheek (23%) and temple (12%). 76% of patients had a history of prior treatment. The lateral orbital wall (41%) was the most common site of invasion, followed by the medial orbital wall (29%) and antero-superior invasion (23%). Age, histology, and location of orbital invasion were associated with disease specific and overall survival. CONCLUSION: Orbital invasion for non-melanoma head and neck skin cancers creates a treatment dilemma and the patterns of invasion are described. In addition, the location of orbital invasion is associated with survival outcomes. PMID- 29465317 TI - Neuroprotective effects of silibinin: an in silico and in vitro study. AB - AIM OF THE STUDY: Astrogliosis is a key contributor for many neurological disorders involving apoptosis, neuroinflammation and subsequent neuronal death. Silibinin, a polyphenol isolated from milk thistle (Silybum marianum), has been shown to suppress the astrocyte activation in various neurodegenerative disorders and also exhibit a neuroprotective role in neuroinflammation-driven oxidative damage. The present study was designed with an aim to investigate the neuroprotective effects of Silibinin against LPS induced oxido-inflammatory cascade and astrocyte activation. MATERIALS AND METHODS: We have used in-silico molecular modelling techniques to study the interaction and binding affinity of silibinin with chemokine receptors associated with neuroinflammation. We have also tested silibinin against LPS induced oxido-inflammatory cascade and astrocyte activation in C6 glia cell lines. RESULTS: In the present study, we found that treatment with silibinin significantly attenuates LPS-oxidative nitrosative stress in C6 astrocytoma cells. We also observed the significant inhibition of induced astrocyte activity after treatment with silibinin. Moreover, molecular modelling studies have proposed a binding pose of silibinin with binding sites of p38 MAPK, CX3CR1 and P2X4 which is an important downstream cascade involved in glia cell activation and neuroinflammation. CONCLUSIONS: Overall, the findings from the current study suggests that silibinin exhibits neuroprotective activity by attenuating oxidative damage and astrocytes activation. PMID- 29465318 TI - Nucleolar stress and sugar response in plants. AB - The processes involved in ribosome biogenesis, including synthesis of ribosomal proteins, ribosome biogenesis-related factors, and ribosomal RNAs (rRNAs), must be coordinately orchestrated in response to changes in energy supply. In animal cells, defects in ribosome biogenesis induce a nucleolar stress response through the p53-mediated pathway. Our recent finding that an essential, sugar-inducible Arabidopsis gene, APUM24, encoded a pre-rRNA processing factor allowed the relationships between rRNA biogenesis, nucleolar stress, sugar response, and growth regulation to be understood in plants. A knockdown mutant of APUM24 developed sugar-dependent phenotypes including pre-rRNA processing defects, reductions in nucleolar size, and limited promotion of leaf and root growth. Alongside the absence of plant p53 homologs and the synchronous sugar-induced expression of ribosome biogenesis-related genes, these findings suggest the following hypothesis. Sugar supply may enhance ribosome biogenesis defects, leading to p53-independent induction of nucleolar stress responses that include negative regulation of growth and development in plants. PMID- 29465319 TI - Sit Still and Pay Attention! Trunk Movement and Attentional Resources in Infants with Typical and Delayed Development. AB - AIMS: (1) examine infant movement during an early posture (sitting) utilizing a novel video assessment technique; and (2) document the differences between infants with typical development (TD), premature infants with motor delay, and infants with cerebral palsy (CP) during focused and nonfocused attention (NFA). METHODS: Infants were tested when they began to sit independently. We utilized Eulerian Video Magnification (EVM) to accentuate small trunk and pelvic movements for visual coding from video taken during a natural play task with and without focused attention (FA). RESULTS: Trunk/pelvic movement varied as a function of both motor skill and attention. Infants with TD and CP made fewer trunk movements during periods of FA than NFA. Preterm infants exhibited more trunk/pelvic movement than the other groups and their movement did not differ based on attention type. CONCLUSIONS: The EVM technique allowed for replicable coding of real-time "hidden" motor adjustments from video. The capacity to minimize extraneous movements in infants, or "sitting still" may allow greater attention to the task at hand, similar to older children and adults. Premature infants' excessive trunk/pelvic movement that did not adapt to task requirements could, in the long term, impact tasks requiring attentional resources. PMID- 29465320 TI - Word Ban? Wherefore "Vulnerable". PMID- 29465321 TI - Dynamics of fixational eye position and microsaccades during spatial cueing: the case of express microsaccades. AB - Microsaccades are systematically modulated by peripheral spatial cues, and these eye movements have been implicated in perceptual and motor performance changes in cueing tasks. However, an additional oculomotor factor that may also influence performance in these tasks, fixational eye position itself, has been largely neglected so far. Using precise eye tracking and real-time retinal-image stabilization, we carefully analyzed fixational eye position dynamics and related them to microsaccade generation during spatial cueing. As expected, during baseline fixation, microsaccades corrected for a foveal motor error away from the preferred retinal locus of fixation (the so-called ocular position "set point" of the oculomotor system). However, we found that this relationship was violated during a short period immediately after cue onset; a subset of cue-directed "express microsaccades" that were highly precise in time and direction, and that were larger than regular microsaccades, occurred. These movements, having <100-ms latencies from cue onset, were triggered when fixational eye position was already at the oculomotor set point when the cue appeared; they were thus error increasing rather than error-decreasing. Critically, even when no microsaccades occurred, fixational eye position itself was systematically deviated toward the cue, again with ~100-ms latency, suggesting that the oculomotor system establishes a new set point at different postcue times. This new set point later switched to being away from the cue after ~200-300 ms. Because eye position alters the location of retinal images, our results suggest that both eye position and microsaccades can be associated with performance changes in spatial cueing tasks. NEW & NOTEWORTHY Covert spatial cueing tasks are a workhorse for studying cognitive processing in humans and monkeys, but gaze is not perfectly stable during these tasks. We found that minute fixational eye position changes, independent of the more studied microsaccades, are not random in cueing tasks and are thus not "averaged out" in analyses. These changes can additionally dictate microsaccade times. Thus, in addition to microsaccadic influences, retinal image changes associated with fixational eye position are relevant for performance in cueing tasks. PMID- 29465322 TI - Learned rather than online relative weighting of visual-proprioceptive sensory cues. AB - When reaching to an object, information about the target location as well as the initial hand position is required to program the motor plan for the arm. The initial hand position can be determined by proprioceptive information as well as visual information, if available. Bayes-optimal integration posits that we utilize all information available, with greater weighting on the sense that is more reliable, thus generally weighting visual information more than the usually less reliable proprioceptive information. The criterion by which information is weighted has not been explicitly investigated; it has been assumed that the weights are based on task- and effector-dependent sensory reliability requiring an explicit neuronal representation of variability. However, the weights could also be determined implicitly through learned modality-specific integration weights and not on effector-dependent reliability. While the former hypothesis predicts different proprioceptive weights for left and right hands, e.g., due to different reliabilities of dominant vs. nondominant hand proprioception, we would expect the same integration weights if the latter hypothesis was true. We found that the proprioceptive weights for the left and right hands were extremely consistent regardless of differences in sensory variability for the two hands as measured in two separate complementary tasks. Thus we propose that proprioceptive weights during reaching are learned across both hands, with high interindividual range but independent of each hand's specific proprioceptive variability. NEW & NOTEWORTHY How visual and proprioceptive information about the hand are integrated to plan a reaching movement is still debated. The goal of this study was to clarify how the weights assigned to vision and proprioception during multisensory integration are determined. We found evidence that the integration weights are modality specific rather than based on the sensory reliabilities of the effectors. PMID- 29465323 TI - Peripheral u-opioid receptors attenuate the responses of group III and IV afferents to contraction in rats with simulated peripheral artery disease. AB - Patients with peripheral artery disease show an exaggerated pressor response to mild exercise, an effect attributable to the exercise pressor reflex, whose afferent arm comprises the thinly myelinated group III and unmyelinated group IV afferents. Previously, we found that DAMGO, a u-opioid agonist injected into the femoral artery, attenuated the exaggerated exercise pressor reflex in rats with ligated femoral arteries, a preparation that simulates the blood flow patterns to muscle that is seen in patients with peripheral artery disease. Continuing this line of investigation, we recorded the responses of group III and IV afferents to static contraction before and after injecting DAMGO (1 ug) into the superficial epigastric artery in rats with patent femoral arteries and in rats with ligated femoral arteries. In rats with patent arteries, DAMGO did not change the responses to contraction of either group III ( n = 9; P = 0.83) or group IV ( n = 8; P = 0.34) afferents. In contrast, in rats with ligated femoral arteries, DAMGO injection (1 ug) significantly decreased the responses to contraction of both group III afferents ( n = 9, P < 0.01) and group IV afferents ( n = 9; P < 0.01). DAMGO did not significantly attenuate the responses of either group III or IV afferents to capsaicin in rats with either patent or ligated femoral arteries. These findings are in agreement with our previous studies that showed that peripheral DAMGO injection attenuated the exercise pressor reflex in rats with ligated femoral arteries but had only a modest effect on the exercise pressor reflex in rats with patent femoral arteries. NEW & NOTEWORTHY In an animal model of peripheral artery disease, we show that the u-opioid agonist, DAMGO reduces the afferent response rate resulting from stimulated static contraction. These results suggest that peripherally active opioid agonists that do not cross the blood-brain barrier may be therapeutic for treatment of peripheral artery disease without the negative and addictive side effects associated with opioids in the central nervous system. PMID- 29465324 TI - May the power be with you: are there highly powered studies in neuroscience, and how can we get more of them? AB - Statistical power is essential for robust science and replicability, but a meta analysis by Button et al. in 2013 diagnosed a "power failure" for neuroscience. In contrast, Nord et al. ( J Neurosci 37: 8051-8061, 2017) reanalyzed these data and suggested that some studies feature high power. We illustrate how publication and researcher bias might have inflated power estimates, and review recently introduced techniques that can improve analysis pipelines and increase power in neuroscience studies. PMID- 29465325 TI - Ultra-fast accurate reconstruction of spiking activity from calcium imaging data. AB - Calcium imaging provides an indirect observation of the underlying neural dynamics and enables the functional analysis of neuronal populations. However, the recorded fluorescence traces are temporally smeared, thus making the reconstruction of exact spiking activity challenging. Most of the established methods to tackle this issue are limited in dealing with issues such as the variability in the kinetics of fluorescence transients, fast processing of long term data, high firing rates, and measurement noise. We propose a novel, heuristic reconstruction method to overcome these limitations. By using both synthetic and experimental data, we demonstrate the four main features of this method: 1) it accurately reconstructs both isolated spikes and within-burst spikes, and the spike count per fluorescence transient, from a given noisy fluorescence trace; 2) it performs the reconstruction of a trace extracted from 1,000,000 frames in less than 2 s; 3) it adapts to transients with different rise and decay kinetics or amplitudes, both within and across single neurons; and 4) it has only one key parameter, which we will show can be set in a nearly automatic way to an approximately optimal value. Furthermore, we demonstrate the ability of the method to effectively correct for fast and rather complex, slowly varying drifts as frequently observed in in vivo data. NEW & NOTEWORTHY Reconstruction of spiking activities from calcium imaging data remains challenging. Most of the established reconstruction methods not only have limitations in adapting to systematic variations in the data and fast processing of large amounts of data, but their results also depend on the user's experience. To overcome these limitations, we present a novel, heuristic model-free-type method that enables an ultra-fast, accurate, near-automatic reconstruction from data recorded under a wide range of experimental conditions. PMID- 29465327 TI - Improving the translational potential of rodent models to study the behavioral and pathophysiological effects of repetitive mild traumatic brain injury. AB - Chronic traumatic encephalopathy (CTE) is thought to be caused by repetitive head impacts. Consequently, there is a need to develop rodent models to better understand the behavioral and pathophysiological changes of repetitive mild traumatic brain injury (rmTBI) and to determine the link between rmTBI and CTE. This Neuro Forum article reviews recent rodent rmTBI models, comparing the impact methods and outcome measures in terms of translational potential. PMID- 29465328 TI - Mechano- and thermosensitivity of injured muscle afferents 20 to 80 days after nerve injury. AB - Chronic injury of limb nerves leading to neuropathic pain affects deep somatic nerves. Here the functional properties of injured afferent fibers in the lateral gastrocnemius-soleus nerve were investigated 20 and 80 days after suturing the central stump of this muscle nerve to the distal stump of the sural nerve in anesthetized rats. Neurophysiological recordings were made from afferent axons identified in either the sciatic nerve (87 A-, 63 C-fibers) or the dorsal root L4/L5 (52 A-, 26 C-fibers) by electrical stimulation of the injured nerve. About 70% of the functionally identified A-fibers had regenerated into skin by 80 days after nerve suture; the remaining A-fibers could be activated only from the injured nerve. In contrast, 93% of the functionally identified C-fibers could only be activated from the injured sural nerve after 80 days. Nearly half of the injured A- (45%) and C-fibers (44%) exhibited ongoing and/or mechanically or thermally evoked activity. Because ~50% of the A- and C-fibers are somatomotor or sympathetic postganglionic axons, respectively, probably all injured muscle afferent A- and C-fibers developed ectopic activity. Ongoing activity was present in 17% of the A- and 46% of the C-fibers. Mechanosensitivity was present in most injured A- (99%) and C-fibers (85%), whereas thermosensitivity was more common in C-fibers (cold 46%, heat 47%) than in A-fibers (cold 18%, heat 12%). Practically all thermosensitive A-fibers and C-fibers were also mechanosensitive. Thus, unlike cutaneous axons, almost all A- and C-fibers afferents in injured muscle nerves demonstrate ectopic activity, even chronically after nerve injury. NEW & NOTEWORTHY After chronic injury of a muscle nerve, allowing the nerve fibers to regenerate to the target tissue, 1) most afferent A-fibers are mechanosensitive and regenerate to the target tissue; 2) ectopic ongoing activity, cold sensitivity, and heat sensitivity significantly decrease with time after injury in A-afferents; 3) most afferent C-fibers do not regenerate to the target tissue; and 4) injured C-afferents maintain the patterns of ectopic discharge properties they already show soon after nerve injury. PMID- 29465326 TI - Corrective response times in a coordinated eye-head-arm countermanding task. AB - Inhibition of motor responses has been described as a race between two competing decision processes of motor initiation and inhibition, which manifest as the reaction time (RT) and the stop signal reaction time (SSRT); in the case where motor initiation wins out over inhibition, an erroneous movement occurs that usually needs to be corrected, leading to corrective response times (CRTs). Here we used a combined eye-head-arm movement countermanding task to investigate the mechanisms governing multiple effector coordination and the timing of corrective responses. We found a high degree of correlation between effector response times for RT, SSRT, and CRT, suggesting that decision processes are strongly dependent across effectors. To gain further insight into the mechanisms underlying CRTs, we tested multiple models to describe the distribution of RTs, SSRTs, and CRTs. The best-ranked model (according to 3 information criteria) extends the LATER race model governing RTs and SSRTs, whereby a second motor initiation process triggers the corrective response (CRT) only after the inhibition process completes in an expedited fashion. Our model suggests that the neural processing underpinning a failed decision has a residual effect on subsequent actions. NEW & NOTEWORTHY Failure to inhibit erroneous movements typically results in corrective movements. For coordinated eye-head-hand movements we show that corrective movements are only initiated after the erroneous movement cancellation signal has reached a decision threshold in an accelerated fashion. PMID- 29465329 TI - Time course of ongoing activity during neuritis and following axonal transport disruption. AB - Local nerve inflammation (neuritis) leads to ongoing activity and axonal mechanical sensitivity (AMS) along intact nociceptor axons and disrupts axonal transport. This phenomenon forms the most feasible cause of radiating pain, such as sciatica. We have previously shown that axonal transport disruption without inflammation or degeneration also leads to AMS but does not cause ongoing activity at the time point when AMS occurs, despite causing cutaneous hypersensitivity. However, there have been no systematic studies of ongoing activity during neuritis or noninflammatory axonal transport disruption. In this study, we present the time course of ongoing activity from primary sensory neurons following neuritis and vinblastine-induced axonal transport disruption. Whereas 24% of C/slow Adelta-fiber neurons had ongoing activity during neuritis, few (<10%) A- and C-fiber neurons showed ongoing activity 1-15 days following vinblastine treatment. In contrast, AMS increased transiently at the vinblastine treatment site, peaking on days 4-5 (28% of C/slow Adelta-fiber neurons) and resolved by day 15. Conduction velocities were slowed in all groups. In summary, the disruption of axonal transport without inflammation does not lead to ongoing activity in sensory neurons, including nociceptors, but does cause a rapid and transient development of AMS. Because it is proposed that AMS underlies mechanically induced radiating pain, and a transient disruption of axonal transport (as previously reported) leads to transient AMS, it follows that processes that disrupt axonal transport, such as neuritis, must persist to maintain AMS and the associated symptoms. NEW & NOTEWORTHY Many patients with radiating pain lack signs of nerve injury on clinical examination but may have neuritis, which disrupts axonal transport. We have shown that axonal transport disruption does not induce ongoing activity in primary sensory neurons but does cause transient axonal mechanical sensitivity. The present data complete a profile of key axonal sensitivities following axonal transport disruption. Collectively, this profile supports that an active peripheral process is necessary for maintained axonal sensitivities. PMID- 29465330 TI - Spatial bias in estimating the position of visual and proprioceptive targets. AB - When people match an unseen hand to a visual or proprioceptive target, they make both variable and systematic (bias) errors. Variance is a well-established factor in behavior, but the origin and implications of bias, and its connection to variance, are poorly understood. Eighty healthy adults matched their unseen right index finger to proprioceptive (left index finger) and visual targets with no performance feedback. We asked whether matching bias was related to target modality and to the magnitude or spatial properties of matching variance. Bias errors were affected by target modality, with subjects estimating visual and proprioceptive targets 20 mm apart. We found three pieces of evidence to suggest a connection between bias and variable errors: 1) for most subjects, the target modality that yielded greater spatial bias was also estimated with greater variance; 2) magnitudes of matching bias and variance were somewhat correlated for each target modality ( R = 0.24 and 0.29); and 3) bias direction was closely related to the angle of the major axis of the confidence ellipse ( R = 0.60 and 0.63). However, whereas variance was significantly correlated with visuo proprioceptive weighting as predicted by multisensory integration theory ( R = 0.29 and 0.27 for visual and proprioceptive variance, respectively), bias was not. In a second session, subjects improved their matching variance, but not bias, for both target modalities, indicating a difference in stability. Taken together, these results suggest bias and variance are related only in some respects, which should be considered in the study of multisensory behavior. NEW & NOTEWORTHY People matching visual or proprioceptive targets make both variable and systematic (bias) errors. Multisensory integration is thought to minimize variance, but if the less variable modality has more bias, behavioral accuracy will decrease. Our data set suggests this is unusual. However, although bias and variable errors were spatially related, they differed in both stability and correlation with multisensory weighting. This suggests the bias-variance relationship is not straightforward, and both should be considered in multisensory behavior. PMID- 29465331 TI - The effect of dimerization on the interaction of ibuprofen drug with calf thymus DNA: Molecularmodeling and spectroscopic investigation. AB - The interaction between the dimer structure of ibuprofen drug (D-IB) and calf thymus DNA under simulative physiological conditions was investigated with the use of Hoechst 33258 and methylene blue dye as spectral probes by the methods of UV-visible absorption, fluorescence spectroscopy, circular dichroism spectroscopy and molecular modeling study.Using the Job's plot, a single class of binding sites for theD-IB on DNA was put in evidence. The Stern-Volmer analysis of fluorescence quenching data shows the presence of both the static and dynamic quenching mechanisms. The binding constants, Kb were calculated at different temperatures, and the thermodynamic parameters ?G?, ?H? and ?S? were given. The experimental results showed that D-IB molecules could bind with DNA via groove binding mode as evidenced by: I. DNA binding constant from spectrophotometric studies of the interaction of D-IB with DNA is comparable to groove binding drugs. II. Competitive fluorimetric studies with Hoechst 33258 have shown that D IB exhibits the ability of this complex to displace with DNA-bounded Hoechst, indicating that it binds to DNA in strong competition with Hoechst for the groove binding. III. There is no significantly change in the absorption of the MB-DNA system upon adding the D-IB, indicates that MB molecules are not released from the DNA helix after addition of the D-IB and are indicative of a non intercalative mode of binding. IV. Small changes in DNA viscosity in the presence of D-IB, indicating weak link to DNA, which is consistent with DNA groove binding. As well as, induced CD spectral changes, and the docking results revealed that groove mechanism is followed by D-IB to bind with DNA. PMID- 29465332 TI - A coaches' perspective on the contribution of anthropometry, physical performance, and motor coordination in racquet sports. AB - Differences and similarities between table tennis and other racquet sports exist, but are not well documented in the literature, in spite of the relevance for talent identification. In this study we aimed at identifying the key characteristics of table tennis in comparison with tennis and badminton based upon a survey in coaches. A total of 177 licensed coaches from all across the world and with diverse professional backgrounds completed a survey on anthropometric measures, physical performance, and motor coordination skills. On a scale from 1 to 10, coaches indicated to what extent a talent characteristic was important for their sport. MANOVA identified key differences as well as similarities between all three racquet sports and a subsequent discriminant analysis allocated coaches correctly for table tennis, tennis, and badminton 81.01%, 55.6%, and 71.4% respectively. Our results show that table tennis and other racquet sport coaches are well aware of differences between the racquet sports and also the importance and value of testing and assortment of skill components. These findings can assist coaches in future talent orientation and transfer in racquet sports. PMID- 29465333 TI - US Fine-Needle Aspiration Biopsy for Thyroid Malignancy: Diagnostic Performance of Seven Society Guidelines Applied to 2000 Thyroid Nodules. AB - Purpose To compare the diagnostic performance of ultrasonography (US)-based fine needle aspiration biopsy (FNAB) criteria from seven international societies in the detection of thyroid malignancy. Materials and Methods This study included a total of 2000 consecutive thyroid nodules (>=1 cm) in 1802 patients with final diagnoses from January 2010 to May 2011. US features of the thyroid nodules were retrospectively reviewed and were classified according to the categories defined by the seven international society guidelines. The diagnostic performance of US based FNAB criteria in the detection of thyroid malignancy and unnecessary FNAB rates were calculated and compared by using a generalized estimating equation method. Results Of the 2000 thyroid nodules, 1546 (78.3%) were benign and 454 (22.7%) were malignant, with papillary carcinoma comprising 85.5% of all malignancies. The Korean Thyroid Association/Korean Society of Thyroid Radiology (KTA/KSThR) (94.5%), National Comprehensive Cancer Network (NCCN) (92.5%), and American Thyroid Association (ATA) (89.6%) guidelines were more sensitive than those of the American Association of Clinical Endocrinologists/American College of Endocrinology/Associazione Medici Endocrinologi (AACE/ACE/AME) (80.4%), American College of Radiology (ACR) (74.7%), French Society of Endocrinology (FSE) (72.7%), and Society of Radiology in Ultrasound (SRU) (70.9%) (P < .001), while the latter guidelines had higher specificity (P < .001). The rate of unnecessary FNAB was lowest with the ACR guidelines (25.3%), followed by the FSE (29.1%), AACE/ACE/AME (32.5%), SRU (45.2%), ATA (51.7%), NCCN (54.0%), and KTA/KSThR (56.9%) guidelines. Conclusion Because the diagnostic performance of US based FNAB criteria varies according to the individual international society guidelines, clinicians should be aware of the strengths and weaknesses of US based FNAB criteria in the management of thyroid nodules.

PMID- 29465334 TI - Association of Mucoid Degeneration of the Anterior Cruciate Ligament at MR Imaging with Medial Tibiofemoral Osteoarthritis Progression at Radiography: Data from the Osteoarthritis Initiative. AB - Purpose To determine whether anterior cruciate ligament (ACL) mucoid degeneration in participants with or at risk for osteoarthritis is associated with longitudinal risk of radiographic progression of medial tibiofemoral compartment joint space loss (JSL). Materials and Methods Baseline demographic, clinical, radiographic, and Magnetic Resonance (MR) Imaging Osteoarthritis Knee Score (MOAKS) data were evaluated in 600 participants from the Osteoarthritis Initiative database. Two blinded musculoskeletal radiologists independently evaluated baseline MR images for ACL mucoid degeneration. Multiple logistic regression was used to investigate the association between ACL mucoid degeneration at MR imaging and JSL progression at radiography, defined as a minimum joint space width decrease greater than 0.7 mm (48 months; cutoff according to mean and standard deviation of 1-year minimum joint space width changes in 90 knees of reference group). Stratified analysis was performed based on baseline cartilage surface damage. Results Knees with ACL mucoid degeneration showed a greater proportion of JSL progression compared with knees with a normal ACL (64% vs 47%; P = .004). After adjustment for all demographic, clinical, radiographic, and MOAKS variables, ACL mucoid degeneration was not statistically significantly associated with JSL progression in the entire cohort (adjusted odds ratio, 1.66; 95% confidence interval: 1.00, 2.77; P = .051). In subgroup analysis, ACL mucoid degeneration was statistically significantly associated with JSL progression in participants with less baseline cartilage surface damage (maximum cartilage surface loss of <=75% in all subregions [P = .015] and <=4 of involved subregions with cartilage surface loss [P = .028]). Conclusion ACL mucoid degeneration in participants with or at risk for osteoarthritis is associated with progression of medial tibiofemoral compartment JSL in knees with less baseline cartilage surface area damage.

AB - During the first two years of life, infants concurrently refine native-language speech categories and word learning skills. However, in the Switch Task, 14-month olds do not detect minimal contrasts in a novel object-word pairing (Stager & Werker, 1997). We investigate whether presenting infants with acoustically salient contrasts (liquids) facilitates success in the Switch Task. The first two experiments demonstrate that acoustic differences boost infants' detection of contrasts. However, infants cannot detect the contrast when the segments are digitally shortened. Thus, not all minimal contrasts are equally difficult, and the acoustic properties of a contrast matter in word learning. PMID- 29465336 TI - Current Emergency Preparedness Resources and Capabilities Among Academic Health Systems in the United States. AB - OBJECTIVE: Although hospital emergency preparedness efforts have been recognized as important, there has been growing pressure on cost containment, as well as consolidation within the US health care system. There is little data looking at what health care emergency preparedness functions have been, could be, or should be centrally coordinated at a system level. METHODS: We developed a questionnaire for academic health systems and asked about program funding, resources provided, governance, and activities. The questionnaire also queried managers' opinions regarding the appropriate role for the system-level resources in emergency response, as well as about what is most helpful at the system-level supporting preparedness. RESULTS: Fifty-two of 97 systems (54%) responded. The most frequently occurring system-wide activities included: creating trainings or exercise templates (75%), promoting preparedness for employees in the system (75%), providing access to specific subject matter experts (73%), and developing specific plans for individual member entities within their system (73%). The top resources provided included a common mass notification system (71%), arranging for centralized contracts for goods and services (71%), and providing subject matter expertise (69%). CONCLUSIONS: Currently, there is wide variation in the resources, capabilities, and programs used to support and coordinate system-level emergency preparedness among academic health systems.

PMID- 29465337 TI - Jatrophihabitans telluris sp. nov., isolated from sediment soil of lava forest wetlands and the emended description of the genus Jatrophihabitans. AB - A novel actinobacterial strain, designated N237T, was isolated from sediment soil of wetlands at Meonmulkkak, Dongbaek-Dongsan, the lava forest, Gotjawal, Jeju, Republic of Korea. Cells of strain N237T were Gram-stain-positive, non-motile rods and formed pale yellow colonies on ten-fold diluted Reasoner's 2A agar. Strain N237T contained iso-C16 : 0 and C17 : 1omega8c as the major fatty acids, MK-9(H4) as the predominant isoprenoid quinone and meso-DAP as the diamino acid in the peptidoglycan. It contained diphosphatidylglycerol, phosphatidylinositol polymannosides, an unidentified phospholipid, an unidentified aminophospholipid, an unidentified aminolipid, two unidentified glycophospholipids, three unidentified glycolipids and two unidentified lipids as polar lipids. The DNA G+C content was 68.1 mol%. Strain N237T formed a separate lineage in the genus Jatrophihabitans, as demonstrated by phylogenetic analysis based on 16S rRNA sequencing. It was most closely related to Jatrophihabitans soli KIS75-12T (95.6 % sequence similarity). The combined phenotypic, chemotaxonomic and phylogenetic characteristics supported the conclusion that strain N237T represents a novel species in the genus Jatrophihabitans, for which the name Jatrophihabitans telluris sp. nov. is proposed. The type strain is N237T (=KCTC 39922T=NRRL B 65477T). PMID- 29465338 TI - Virgibacillus phasianinus sp. nov., a halophilic bacterium isolated from faeces of a Swinhoe's pheasant, Lophura swinhoii. AB - A rod-shaped, Gram-stain-positive, motile and aerobic bacterium, designated LM2416T, was isolated from faeces of Lophuras winhoii living in Seoul Grand Park, Gyeonggi-do, Republic of Korea. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain LM2416T belonged to the genus Virgibacillus, sharing high 16S rRNA gene sequence similarities to Virgibacillus necropolis LMG 19488T (99.0 %), Virgibacillus carmonensis LMG 20964T (98.4 %), Virgibacillus arcticus Hal 1T (98.3 %) and Virgibacillus flavescens S1-20T (97.9 %). The isolate grew at 10-30 degrees C, pH 6-7 and 0-20 % (w/v) NaCl. Optimal growth was observed at 30 degrees C, pH 6-7 and 10 % (w/v) NaCl. The major fatty acid was anteiso-C15 : 0. Polar lipids were composed of phosphatidylglycerol, diphosphatidylglycerol, three unknown phospholipids and two unknown aminophospholipids. The main menaquinone was MK-7. Strain LM2416T had alanine, lysine, glutamic acid, glycine and aspartic acid as cell-wall amino acids and ribose as a cell-wall sugar. The whole genome sequences of strain LM2416T and V. necropolis KCTC 3820T were sequenced by PacBio RS II sequencing. The genome sequence-based G+C content of strain LM2416T was 39.5 mol%. The orthologous average nucleotide identity value, showing genetic relatedness between strain LM2416T and V. necropolis KCTC 3820T, was 78.3 %. Based on the phylogenetic, biochemical, chemotaxonomic and genotypic data presented in this study, strain LM2416T is considered to represent a novel species of the genus Virgibacillus, for which the name Virgibacillus phasianinus is proposed. The type strain is LM2416T (=KCTC 33927T=JCM 32144T). PMID- 29465339 TI - Edaphobacter lichenicola sp. nov., a member of the family Acidobacteriaceae from lichen-dominated forested tundra. AB - An isolate of aerobic, Gram-stain-negative, rod-shaped, non-motile and light-pink pigmented bacteria, designated SBC68T, was obtained from slightly decomposed thalli of the lichen Cladonia sp. collected from the forested tundra of north western Siberia. Cells of this isolate occurred singly, in pairs or in rosettes. These bacteria were acidophilic (optimum growth at pH 4.3-5.6) and mesophilic (optimum growth at 20-30 degrees C) but were also capable of growth at low temperatures, down to 7 degrees C. The preferred growth substrates were sugars, some organic acids and lichenan. The major fatty acids were iso-C15 : 0, C16 : 1omega7c, C16 : 0, C16 : 1omega7t, and 13,16-dimethyl octacosanedioic acid. The only quinone was MK-8, and the G+C content of the DNA was 54.7 mol%. SBC68T represented a member of the family Acidobactericeae; the closest taxonomically described relatives were Edaphobacter dinghuensis DHF9T and Granulicella aggregans TPB6028T (97.2 and 97.1 % 16S rRNA gene sequence similarity, respectively). In 16S rRNA gene-based trees, SBC68T clustered together with species of the genus Edaphobacter. However, this isolate differed from all previously described species of the genus Edaphobacter with respect to the pink pigmentation, formation of cell rosettes and substrate utilization pattern. On the basis of these data, strain SBC68T should be considered to represent a novel species of acidobacteria, for which the name Edaphobacterlichenicola sp. nov. is proposed. The type strain is SBC68T (=DSM 104462T=VKM B-3208T). PMID- 29465341 TI - Microbe Profile: Corynebacterium diphtheriae - an old foe always ready to seize opportunity.

Diphtheria was a major cause of childhood mortality prior to the introduction of the toxoid vaccine, yet it is capable of rapid resurgence following the breakdown of healthcare provision, vaccination or displacement of people. The mechanism and treatment of toxin-mediated disease is well understood, however there are key gaps in our knowledge on the basic biology of C. diphtheriae particularly relating to host colonisation, the nature of asymptomatic carriage, population genomics and host adaptation. PMID- 29465340 TI - Bacillus alkalitolerans sp. nov., isolated from marine sediment near a hydrothermal vent. AB - A Gram-stain-positive, endospore-forming, rod-shaped, motile and strictly aerobic strain, designated T3-209T, was isolated from sediment sampled at a water depth of 1206 m of the southern Okinawa Trough at station T1 (25.07 degrees N, 122.58 degrees E) near the Tangyin hydrothermal vent during an expedition on the R/V Kexue in May 2014. The strain was able to grow at a temperature range of 10-42 degrees C (optimum 28 degrees C). Growth was observed at NaCl concentrations (w/v) of 0-6 % (optimum 0 %). The pH range for growth was 7.0-9.0 (optimum 8.0). The 16S rRNA gene sequence analysis indicated that strain T3-209T belonged to the genus Bacillus within the family Bacillaceae and was most closely related to Bacillus drentensis LMG 21831T and Bacillus bataviensis LMG 21833T, with the same sequence similarity (97.0 %), but shared relatively low levels of similarity (92.6-96.9 %) to the type strains of other Bacillus species. The peptidoglycan type of strain T3-209T was meso-diaminopimelic acid. The predominant cellular fatty acids were anteiso-C15 : 0, iso-C15 : 0 and alcohol-C16 : 1omega7c. The respiratory quinone was menaquinone-7. The polar lipids of strain T3-209T comprised phosphatidylglycerol, two unidentified phospholipids and one unidentified aminolipid. The DNA G+C content was 41.8 mol%. Combining results of phylogenetic analysis, phenotypic characterization and chemotaxonomic studies, strain T3-209T represents a novel species of the genus Bacillus, for which the name Bacillus alkalitolerans sp. nov. is proposed. The type strain is T3-209T (=KCTC 33631T=DSM 29135T=MCCC 1K00503T). PMID- 29465342 TI - Lack of glyoxylate shunt dysregulates iron homeostasis in Pseudomonas aeruginosa. AB - The aceA and glcB genes, encoding isocitrate lyase (ICL) and malate synthase, respectively, are not in an operon in many bacteria, including Pseudomonas aeruginosa, unlike in Escherichia coli. Here, we show that expression of aceA in P. aeruginosa is specifically upregulated under H2O2-induced oxidative stress and under iron-limiting conditions. In contrast, the addition of exogenous redox active compounds or antibiotics increases the expression of glcB. The transcriptional start sites of aceA under iron-limiting conditions and in the presence of iron were found to be identical by 5' RACE. Interestingly, the enzymatic activities of ICL and isocitrate dehydrogenase had opposite responses under different iron conditions, suggesting that the glyoxylate shunt (GS) might be important under iron-limiting conditions. Remarkably, the intracellular iron concentration was lower while the iron demand was higher in the GS-activated cells growing on acetate compared to cells growing on glucose. Absence of GS dysregulated iron homeostasis led to changes in the cellular iron pool, with higher intracellular chelatable iron levels. In addition, GS mutants were found to have higher cytochrome c oxidase activity on iron-supplemented agar plates of minimal media, which promoted the growth of the GS mutants. However, deletion of the GS genes resulted in higher sensitivity to a high concentration of H2O2, presumably due to iron-mediated killing. In conclusion, the GS system appears to be tightly linked to iron homeostasis in the promotion of P. aeruginosa survival under oxidative stress.

AB - Mycobacterium tuberculosis is an expert and deadly pathogen, causing the disease tuberculosis (TB) in humans. It has several notable features: the ability to enter non-replicating states for long periods and cause latent infection; metabolic remodelling during chronic infection; a thick, waxy cell wall; slow growth rate in culture; and intrinsic drug resistance and antibiotic tolerance. As a pathogen, M. tuberculosis has a complex relationship with its host, is able to replicate inside macrophages, and expresses diverse immunomodulatory molecules. M. tuberculosis currently causes over 1.8 million deaths a year, making it the world's most deadly human pathogen. PMID- 29465343 TI - Stackebrandtia soli sp. nov., a novel actinobacterium isolated from a soil sample. AB - An aerobic actinobacterium, strain AN130378T, was isolated from a soil sample collected in Korea and subjected to taxonomic investigation using a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequence data showed that strain AN130378T is a member of the genus Stackebrandtia, with sequence similarities of 97.3 % to Stackebrandtia albiflava YIM 45751T and 97.1 % to Stackebrandtia endophytica YIM 64602T. The whole-cell hydrolysates contained meso diaminopimelic acid as the diagnostic diamino acid, and galactose, glucose and xylose. The major menaquinones were MK-11(H4), MK-10(H4) and MK-11(H6), while the major fatty acids were identified as iso-C15 : 0, anteiso-C17 : 0, anteiso-C15 : 0, iso-C17 : 0 and summed feature 3 (C16 : 1omega6c and/or C16 : 1omega7c). The polar lipids were identified as diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylmethylethanolamine, an unidentified aminophospholipid, four unidentified glycolipids, three unidentified phospholipids and two unidentified polar lipids. The G+C content of the genomic DNA was determined to be 67.7 mol%. All chemotaxonomic and genotypic data indicated that the strain belongs to the genus Stackebrandtia. On the basis of morphological, chemotaxonomic data and phylogenetic analysis, strain AN130378T is considered to represent a novel species within the genus Stackebrandtia, for which the name Stackebrandtia soli sp. nov. is proposed. The type strain is AN130378T (=DSM 103573T=KCTC 39809T). PMID- 29465345 TI - The group I alphabaculovirus-specific protein, AC5, is a novel component of the occlusion body but is not associated with ODVs or the PIF complex. AB - Autographa californica nucleopolyhedrovirus (AcMNPV) orf5 (ac5) is a group I alphabaculovirus-specific gene of unknown function, although the protein (AC5) was previously reported to be associated with the per os infectivity factor (PIF) complex. The purpose of this study was to study the dynamics of AC5 during AcMNPV infection and to verify whether it is indeed a component of the PIF complex. Transcription and expression analyses suggested that ac5 is a late viral gene. An ac5-deleted recombinant AcMNPV was generated by homologous recombination. A one step growth curve assay indicated that ac5 was not required for budded virus (BV) production in Sf9 cells. Scanning electron microscopy and transmission electron microscopy demonstrated that the deletion of ac5 did not affect occlusion body (OB) morphology, and nor did it affect the insertion of occlusion-derived virus (ODV) into OBs. Partially denaturing SDS-PAGE and a co-immunoprecipitation assay clearly showed that AC5 was not a component of the PIF complex, while the deletion of ac5 did not affect the formation and presence of the PIF complex. Further analyses showed, however, that AC5 was an OB-specific protein, but it was not detected as a component of BVs or ODVs. Bioassay experiments showed that the oral infectivity of ac5-deleted AcMNPV to third instar Spodoptera exigua larvae was not significantly different from that of the ac5-repaired virus. In conclusion, AC5 is an intrinsic protein of OBs, instead of being a component of the PIF complex, and is not essential for either BV or ODV infection. AC5 is awaiting the assignment of another hitherto unknown function. PMID- 29465346 TI - IL-6 receptor inhibition modulates type III collagen and C-reactive protein degradation in rheumatoid arthritis patients with an inadequate response to anti tumour necrosis factor therapy: analysis of connective tissue turnover in the tocilizumab RADIATE study. AB - OBJECTIVES: The objective of this study was to examine the tissue degradation in response to anti-IL6 receptor treatment in rheumatoid arthritis (RA) patients which are anti-TNF-alpha inadequate responders. METHODS: RADIATE was a randomised, double-blinded, placebo-controlled, parallel-group, phase III trial. RA patients with previous inadequate response to anti-TNFalpha therapy (n=299) were randomly assigned to tocilizumab 4 or 8 mg/kg with methotrexate (10-25 mg weekly) or placebo with methotrexate. Type III collagen degradation (C3M) and CRP degradation (CRPM) were analysed in serum samples at baseline and 16 weeks. RESULTS: Treatment with 4 and 8 mg/kg tocilizumab significantly decreased C3M (p=0.0001 and p=0.0007) and CRPM (p<0.0001) levels after 16 weeks. Changes in C3M and CRPM levels after 16 weeks correlated well with the changes in disease activity score 28 (DAS28). Change in CRPM levels furthermore correlated moderately with the change in patient pain (VAS) (rpartial of 0.20) and Health assessment questionnaire disability index (HAQ-DI) (rpartial of 0.24). Changes in biomarker levels above median change led to an odds ratio of 1.95 (C3M) and 3.00 (CRPM) for achieving the American College of Rheumatology 20% improvement criteria (ACR20). CONCLUSIONS: This study shows that a decrease in inflammation leads to a decrease in excessive extracellular matrix degradation. It furthermore supports earlier shown evidence that tocilizumab works in the treatment of RA patients, although there is a clear need for identifying and selecting patients who are more likely to respond to treatment. PMID- 29465347 TI - An increased major vessel uptake by 18F-FDG-PET/CT in NIH criteria inactive patients with Takayasu's arteritis. AB - OBJECTIVES: The commonly adopted method of defining active disease in Takayasu's arteritis (TAK) is the definition used by the US National Institutes of Health (NIH). A gold standard in imaging techniques for assessing disease activity in TAK has not been clearly established and the creation of practical and valid tools represents a challenge. To assess whether 18F-FDG-PET/CT and NIH criteria show a good level of agreement in assessing disease activity of TAK patients. METHODS: 18F-FDG-PET/CT was performed in 17 patients with TAK. All 17 patients fulfilled the clinical criteria according to the American College of Rheumatology criteria. Two nuclear physicians visually assessed the degree of 18F-FDG uptake in the inflammatory vascular lesion. 18F-FDG-PET/CT and the inflammatory vascular lesion were evaluated by using the standardised uptake value (SUV) of 18F-FDG accumulation were interpreted as active vasculitic lesions. RESULTS: Of the 17 patients, 6 were in the active stage and 11 were in the inactive stage according to the level of disease activity as clinically assessed by the NIH criteria. No significant 18F-FDG accumulation was observed in the patients with inactive disease (SUV<=1.2). 18F-FDG-PET/CT localised 18F-FDG accumulation in the inflammatory lesion in the patients with TAK who had inactive disease (n=3) assessed by the NIH criteria. 18F-FDG PET/CT revealed intense 18F-FDG accumulation (SUV max 2.88) in the vasculature of 3 patients in the inactive stage of TAK. The other 8 patients in the active stage showed weak 18F-FDG accumulation (SUV <=1.2). CONCLUSION: 18FDG-PET/CT appears to be a promising technique for the diagnosis and assessment of disease activity in patients of TAK, even those considered to be inactive by the NIH criteria. However, it needs to be validated in larger groups for cost-effectiveness and sensitivity to change. PMID- 29465348 TI - Increased circulating CD14brightCD16+ intermediate monocytes are regulated by TNF alpha and IL-6 axis in accordance with disease activity in patients with rheumatoid arthritis. AB - OBJECTIVES: Although circulating CD14brightCD16+ monocyte subsets are increased in inflammatory disease, the pathogenesis of the increase in the inflammatory condition of the cells is still unclear and the relationship to cytokines is unknown particularly in rheumatoid arthritis (RA). The purpose of this study was to investigate the influence anti-cytokine treatment has on CD14brightCD16+ monocytes in patients with RA. METHODS: Thirty-two RA patients and 14 healthy volunteers (HV) were enrolled in this study. All the patients had never been treated with methotrexate (MTX) or biological agents. Peripheral blood samples and clinical information of the patients were obtained at the time of 0, 12 and 24 weeks of treatment. Peripheral blood samples were also obtained from the HV. The expression levels of CD14 and CD16 on monocytes were measured by flow cytometry (FCM). RESULTS: Eight patients received anti-interleukin (IL)-6 receptor antibody, tocilizumab (TCZ) treatment alone, 12 patients received anti tumour necrosis factor (TNF)-alpha antibody, adalimumab (ADA) with MTX treatment and the others received only MTX treatment. FCM analysis revealed that the proportion of CD14brightCD16+ monocytes significantly increased in patients at baseline compared with HV. The proportion of CD14brightCD16+ monocytes significantly decreased after TCZ, and ADA with MTX treatment. The proportion of intermediate monocytes was significantly and positively correlated with disease activity and it improved in accordance with the proportion of CD14brightCD16+ monocytes after inhibition of signal transduction of inflammatory cytokines. CONCLUSIONS: We showed that the population of CD14brightCD16+ monocytes significantly decreased with the change of disease activity by key cytokines, IL 6 or TNF-alpha signal blockade in RA. This result indicates that the proportion of those monocytes is important for reflecting disease activity in RA. PMID- 29465349 TI - Association of depression with socioeconomic status, anticardiolipin antibodies, and organ damage in patients with systemic lupus erythematosus: results from the KORNET registry. AB - OBJECTIVES: Depression is more common in patients with systemic lupus erythematosus (SLE) compared to the general population. However, few studies have investigated risk factors of depression in SLE patients, and the results are inconsistent. This study evaluated the prevalence of, and risk factors for, depression in ethnically homogeneous Korean SLE patients. METHODS: In this study, 505 consecutive SLE patients were enrolled from the Korean Lupus Network registry. Demographic variables, clinical manifestations, laboratory findings, physician global assessment, and SLEDAI-2000 and SLICC damage index were recorded at enrolment. Patients were identified as having depressive symptoms using the Korean version of the Beck Depression Inventory (BDI) with a cut-off >=16, and categorised into four groups. Multivariable logistic regression analyses were performed to identify independent risk factors for depression defined as a BDI score >=16. RESULTS: Of the 505 patients, 97 (19.2%) were diagnosed with depression. Patients with a higher BDI score were older, more likely to be a current smoker, and had a SLICC score >1. Conversely, they had lower income and educational levels. Regarding the serologic findings, patients with a higher BDI score had lower anti-double-stranded DNA positivity and higher anticardiolipin (aCL) positivity. On multivariate analysis, the following factors were associated with depression: current smoking status (OR 2.533, p=0.049), aCL-positivity (OR 2.009, p=0.035), and a SLICC damage index score >1 (OR 2.781, p=0.039). On the other hand, high-level education (OR 0.253, p=0.024) and a high income (OR 0.228, p=0.008) were negatively associated with depression. CONCLUSIONS: Our results show that depression is prevalent in patients with SLE and multiple factors are associated with depression in SLE. These data could help guide target programmes for those at high risk of depression in SLE. PMID- 29465350 TI - The association of endothelial nitric oxide synthase gene single nucleotide polymorphisms with paediatric systemic lupus erythematosus. AB - OBJECTIVES: Endothelial nitric oxide synthase (eNOS) is a type of nitric oxide synthase that mainly exists in the endothelium. It produces nitric oxide (NO) to regulate the function of endothelial cells. Endothelial dysfunction and increased NO metabolites have been shown in animal models of lupus and in lupus patients, so eNOS gene polymorphisms may be important in the pathogenesis of SLE. This study aimed to investigate the association of the single nucleotide polymorphisms (SNPs) of eNOS and paediatric systemic lupus erythematosus (pSLE). METHODS: A total of 91 pSLE cases and 90 healthy controls were used in this study. We divided these patients into 4 subgroups according to kidney or central nervous system involvement. Four selected SNPs in the gene were analysed with MALDI-TOF mass spectrometry. Statistical methods were carried out to investigate the correlation between the SNPs and pSLE. RESULTS: SNP rs1808593 genotype GT in case group were significantly higher than those in the control group (p=0.047), and the genotype GT had positive correlation with pSLE (OR=1.93, 95% CI: 1.01-3.69). In subgroup C (the patients with central nervous system but no kidney damage), the genotype GT was significantly higher than those in the control group (p=0.028), and the genotype GT was related to pSLE with central nervous system damage (OR=6.24, 95% CI: 1.17-33.15). In male patients, we found SNP rs1808593 genotype GT in pSLE group was significantly higher than in the control group (p=0.0065), and the risk of pSLE increased in patients with genotype GT (OR=8.36, 95% CI: 2.02-34.6). CONCLUSIONS: SNP rs1808593 GT genotype is significantly higher than that in the control group, which may indicate that this genotype increases the risk of pSLE, especially in boys, and also this genotype might increase the risk of central nervous system involvement. Therefore, eNOS gene SNP rs1808593 genotype may have an important role in predicting the occurrence of pSLE and central nervous system complications in pSLE. PMID- 29465351 TI - Increased remodelling of interstitial collagens and basement membrane is suppressed by treatment in patients with rheumatoid arthritis: serological evaluation of a one-year prospective study of 149 Japanese patients. AB - OBJECTIVES: This prospective study aimed to use serological biomarkers for evaluation of, connective tissue turnover, in a population of 149 Japanese patients with rheumatoid arthritis (RA). It was aimed to investigate how the connective tissue was affected by treatment at follow-up after 1 year (+/- 6 weeks) with either methotrexate (n=23) alone, or in combination with: adalimumab (n=49), tofacitinib (n=27) or tocilizumab (n=50). METHODS: Clinical characteristics were collected and connective tissue turnover, was evaluated by 4 serological biomarkers: C1M and C3M reflect degradation of types I and III collagen in interstitial tissue; C4M, reflecting degraded type IV collagen of the basement membranes; and CRPM, a marker of degraded C-reactive protein. Evaluated biomarker levels were measured at baseline and at follow-up. Levels were compared to the reference levels of healthy individuals. RESULTS: The four evaluated biomarkers were all elevated at baseline in patients with RA compared to healthy individuals. The biomarkers were higher in RA patients compared to healthy individuals at baseline and they were all significantly correlated with disease activity score of 28 joint (DAS28) (p<0.0001). The biomarker levels were all significantly decreased in all four patient groups at follow-up in all of the four treatment groups. CONCLUSIONS: Rheumatoid joint inflammation elicits enhanced turnover of major collagen constituents of the synovial membrane and this abnormal pathway may be implicated in erosive progression. Evaluations of the applied biomarkers: C1M, C3M, C4M and CRPM, indicate that the pathologically enhanced tissue turnover was attenuated, by all of the four studied treatments. PMID- 29465352 TI - Immune response against the coiled coil domain of Sjogren's syndrome associated autoantigen Ro52 induces salivary gland dysfunction. AB - OBJECTIVES: The structural domains of Ro52, termed the RING, B-box, coiled coil (CC) and B30.2/SPRY are targets of anti-Ro52 in multiple autoimmune disorders. In Sjogren's syndrome patients, the presence of anti-Ro52 is associated with higher disease severity, and in mice, they induce salivary gland hypofunction. This study was undertaken to investigate whether immune responses against different domains of Ro52, influences salivary gland disease in mice. METHODS: Female NZM2758 mice were immunised with Ro52 domains expressed as recombinant fusion proteins with maltose binding protein (MBP) [MBP-RING-B-box, MBP-CC, MBP CC(DeltaC19), MBP-B30.2/SPRY]. Sera from immunised mice were studied for IgG antibodies to Ro52 by immunoprecipitation, and to salivary gland cells by immunofluorescence. Pilocarpine-induced saliva production was measured to evaluate salivary gland function. Submandibular glands were investigated by histopathology for inflammation and by immune-histochemistry for IgG deposition. RESULTS: Mice immunised with different Ro52-domains had comparable reactivity to Ro52 and to salivary gland cells. However, only mice immunised with the CC domain and its C-terminal truncated version CC(DeltaC19) showed a significant drop in saliva production. None of the mice developed severe salivary gland inflammation. The salivary gland hypofunction significantly correlated with increased intra lobar IgG deposits in the submandibular salivary glands. CONCLUSIONS: Our data demonstrate that epitope specificity of anti-Ro52 antibodies plays a critical role in the induction of glandular dysfunction. Clearly, screening Sjogren's syndrome patients for relative levels of Ro52 domain specific antibodies will be more informative for associating anti-Ro52 with clinical measures of the disorder. PMID- 29465353 TI - Serum IgG ACPA-IgM RF immune complexes were detected in rheumatoid arthritis patients positive for IgM ACPA. AB - OBJECTIVES: Since the presence of IgM antibodies is a hallmark of ongoing immune response, we aimed to identify immunologically active rheumatoid arthritis (RA) patients by detecting IgM anti-citrullinated protein antibody (ACPA) levels. METHODS: IgM ACPA levels were determined in the serum of 176 RA patients by enzyme-linked immunosorbent assay, in which parameters of reactivity against citrullinated and non-citrullinated peptides were compared to ensure the specificity. Influence of IgM rheumatoid factor (RF) on IgM ACPA detection was examined by removing IgG, using protein G-conjugated beads, or by purifying ACPA, using citrullinated peptide-conjugated beads. RESULTS: Although IgM specific for citrullinated proteins was detected in some patients (11%), IgM molecules reactive to both citrullinated and non-citrullinated peptides were detected in a substantial number of patient samples (12%). IgM ACPA-positive reactions were associated with the presence of IgG ACPA and IgM RF. Surprisingly, protein G mediated removal of IgG from the serum eliminated positivity for IgM ACPA, suggesting that IgG ACPA-IgM RF complex was being detected. This assumption was confirmed by the detection of IgM RF in the eluate of protein G beads and citrullinated peptide-conjugated beads. CONCLUSIONS: In an attempt to detect IgM ACPA, we mostly revealed false positive reactions due to the presence of IgM molecules, which were not specific for citrullinated proteins, and IgG ACPA-IgM RF immune complex. The latter complex had been proposed to play a role in the pathogenesis of RA, and here, for the first time, we have demonstrated its presence in the sera of RA patients. PMID- 29465354 TI - Self-reported childhood maltreatment, lifelong traumatic events and mental disorders in American and Israeli rheumatoid arthritis patients. AB - OBJECTIVES: Psychological stress is thought to play a major role in the development and exacerbation of autoimmune diseases in general, as well as in rheumatoid arthritis (RA) in particular. The aims of the current study are to compare retrospective self-reports of childhood maltreatment and lifetime major life/traumatic experiences of American and Israeli RA patients, using standardised instruments, while adjusting for concomitant mental disorders and psychological distress, in order to rule out their part in the subjective reports, thus addressing the trans-cultural robustness of the association between childhood maltreatment, traumatic experiences and RA. METHODS: RA patients at the participating study centres were recruited by their physicians, both in Israel and the USA. Patients filled out questionnaires regarding demographic data, disease activity, psychological distress, potential anxiety and potential depression. In addition, patients answered questions regarding pain and childhood maltreatment. RESULTS: 83 RA patients were recruited in the US and 23 patients in Israel. The comparison of CTQ-subscales between the US and Israeli cohorts showed significant differences between the groups only in the subscales of emotional neglect (US 10.30+/-5.05, Israeli 22.67+/-3.68, p<0.05) and emotional abuse (US 10.46+/-5.77, Israeli 7.13+/-4.84, p<0.05). 87% of Israeli patients had severe emotional neglect. Severe emotional abuse was associated with probable depression (OR 7.778, CI [1.907-31.716]). Using Pain Disability Index (PDI) score, Americans reported more pain during sexual activity than Israelis (US PDI Score 5.64+/ 3.70. Israeli 3.16+/-3.86, p<0.05). PDI score was also associated with a previous traumatic event (36.89+/-18.57 vs. 16.82+/-14.85, p<0.05). CONCLUSIONS: A high degree of similarity was demonstrated between American and Israeli populations of RA patients, regarding psychological stressors and previous traumatic events. As expected, the results indicated a link between emotional abuse and depression in these patients. In addition, a previous traumatic event was associated with more significant pain. Physicians caring for RA patients should be vigilant regarding the possible association with childhood adversity and should consider appropriate consultations when indicated. In addition, while dealing with pain management in RA patients, physicians should keep in mind the possible contribution of distant childhood adversity. PMID- 29465355 TI - Functional characterisation of ADP ribosylation factor-like protein 15 in rheumatoid arthritis synovial fibroblasts. AB - OBJECTIVES: ARL15 is a novel susceptibility gene identified in a recent GWAS in a north Indian rheumatoid arthritis (RA) cohort. However, the role of ARL15 or ARF family genes in RA aetiology remains unknown. Therefore, we aimed to i) establish the expression of ARL15 in rheumatoid arthritis synovial fibroblasts (RASF) and ii) its functional characterisation by assessing its effects on major inflammatory cytokines and interacting partners using a knockdown approach. METHODS: RASF were cultured from synovial tissue obtained from RA patients (n=5) and osteoarthritis (OA) patients (n=3) serving as controls. Expression of ARL15, ARF1 and ARF6 in RASF was checked by semi-quantitative PCR and western blots; and altered expression of ARL15, if any, by induction of RASF with TNF using real time PCR. The effect of ARL15 on the expression of adiponectin, adiponectin receptor I, IL6 and GAPDH and on cell mobility by invasion and migration assays were assessed by siRNA mediated gene knockdown. RESULTS: Expression of ARL15, ARF1 and ARF6 was confirmed in RASF and OASF samples but ARL15 expression remained unaltered on TNF induction. Notably, ARL15 knockdown resulted in downregulation of IL6 and GAPDH, upregulation of adiponectin and adiponectin receptor I genes; and significant reduction in migration and invasion of RASF. Genemania showed significant interactions of ARL15 with genes responsible for insulin resistance and phospholipase D. CONCLUSIONS: This first report on ARL15 expression in RASF and its likely role in inflammation and metabolic syndromes through a TNF independent pathway, encourages hypothesis-free studies to identify additional pathways underlying RA disease biology.

PMID- 29465357 TI - Molecular recognition patterns of anti-topoisomerase I-antibodies in patients with systemic sclerosis before and after autologous stem cell transplantation. AB - OBJECTIVES: To evaluate the effect of autologous stem cell transplantation (aSCT) on antibody (ab) reactivity towards linear epitopes of topoisomerase-I (topo I/Scl70) in patients with systemic sclerosis (SSc) and to correlate antibody reactivities with clinical outcome after aSCT. METHODS: Fourteen anti-topo I/Scl70-positive SSc-patients were analysed before and after non-myeloablative aSCT. Five patients showed ongoing good response (group 1), 9 had primarily responded but later relapsed or did not respond (group 2). Patients' sera were tested by ELISA against full length (fl) topo-I and 45 overlapping 25-mer peptides. Furthermore, for comparison sera from patients with anti-topo-I negative SSc (n=12), other collagen disorders (n=6), and from 21 healthy controls (HC) were analysed. RESULTS: Anti-topo-I-positive SSc-sera showed significantly higher IgG-reactivity as compared to HC towards 34 of the 45 peptides. Especially peptide 39 (aa647-671) emerged as a immunodominant epitope being recognised predominantly by anti-topo-I-positive SSc-sera. Reactivity towards 17 of the 45 peptides decreased after aSCT in group 1- and 2-patients. Before aSCT, group 1 patients had lower antibody reactivity towards peptide 39 than group 2-patients. There was no change in peptide-specificity after aSCT. CONCLUSIONS: Reactivity towards topo-I-epitopes is heterogeneous in SSc, but peptide 39 (aa647-671) may be another immunodominant epitope besides the published epitope aa489-573. Antibody reactivity to this peptide 39 was higher in group 2- than in group 1 patients. Peptide recognition pattern did not change after aSCT.

PMID- 29465359 TI - Socio-economic inequalities in occurrence and health care costs in rheumatic and musculoskeletal diseases: results from a Spanish population-based study including 1.9 million persons. AB - OBJECTIVES: To explore and compare the impact of socio-economic deprivation on the occurrence of the major rheumatic and musculoskeletal diseases (RMDs) and health care costs. METHODS: Data on diagnoses, socio-demographics and health care costs of the entire adult population of the Basque Country (Spain) was used. Area deprivation index included five categories (1 to 5 (most deprived)). Cost categories included primary and specialist care, emergency room, hospitalisations, and drug prescriptions. Twenty-nine RMDs were grouped into seven groups: Rheumatoid Arthritis, Spondyloarthritis, Crystal Arthropathies, Osteoarthritis, Soft Tissue Diseases, Connective Tissue Diseases, and Vasculitis. The relations between the deprivation and the occurrence of RMD and costs were explored in regression models adjusted for relevant confounders. RESULTS: Data from 1,923,156 adults were analysed. Mean age was 49.9 (SD18.4) years, 49% were males. Soft tissue diseases were the most prevalent RMD (5.5%, n=105,656), followed by osteoarthritis (2.2%, n=41,924). Socio-economic deprivation was associated with higher likelihood to have any of the 29 RMDs. The strongest socio economic gradient was seen for the soft tissue diseases (OR 1.82 [95%CI 1.78;1.85], most vs. least deprived), followed by osteoarthritis (OR 1.59 [1.54;1.64]). Deprivation was also associated with higher costs across the majority of the conditions however patterns were more blurred, and inverse relationship was observed for connective tissue diseases, gout, hip osteoarthritis and undifferentiated (poly)arthritis. CONCLUSIONS: Socio-economic deprivation is associated with increased occurrence of all RMDs, and in most cases more deprived patients incur higher health care costs.

AB - OBJECTIVES: To identify biomarkers for disease activity in IgG4-related disease (IgG4-RD) and primary Sjogren's syndrome (pSS). METHODS: Forty-three consecutive treatment-naive patients with IgG4-RD, 62 patients with pSS, and 5 patients with sicca syndrome were enrolled. IgG4-RD and pSS disease activity was assessed based on the IgG4-RD responder index (IgG4-RD RI) and EULAR Sjogren's Syndrome Disease Activity Index (ES- SDAI), respectively. The associations of biomarkers with disease activity were examined. RESULTS: Comparison of the three dis- eases identified the serum levels of IgG, IgG4, IgG4/IgG ratio, IgE, and soluble interleukin-2 receptor (sIL-2R) for IgG4-RD and the serum levels of IgM and sIL 2R and lymphocyte counts for pSS as potential biomarkers of disease activity. Among these, serum sIL-2R levels correlate with baseline IgG4-RD RI scores and the number of affected organs in IgG4-RD (rho=0.74, p<0.0001 and rho=0.75, p<0.0001, respectively). Serum sIL-2R levels also correlate with ESSDAI scores and the number of af- fected organs in pSS (rho=0.67, p<0.0001 and rho=0.41, p<0.0001, respectively). Receiver operating characteristic curve analysis suggested serum sIL-2R levels as an efficient biomarker to distinguish the presence of extra-dacryosialadenitis involvements in IgG4-RD with a cut-off value of 424 U/mL (AUC=0.93, p<0.0001), and in pSS with 452 U/mL (AUC=0.89, p<0.0001). Serum sIL-2R levels decreased significantly after treatment in patients with IgG4 RD and pSS. CONCLUSIONS: Serum sIL-2R levels are a potentially valuable biomarker for evaluating disease activity and treatment response in IgG4-RD and pSS.

AB - OBJECTIVES: Systemic sclerosis (SSc) is a chronic, autoimmune connective tissue disease with a female predominance. The reason for the female predilection in SSc may relate to the difference in hormones between the genders. There are no current data on the influence male-to-female sex transition may have in the development of SSc. We report three patients who developed SSc after initiating the transgender process, and review current literature in regards to transgender patients with connective tissue disease (CTD). METHODS: We describe the clinical features and disease course of three transgender patients who developed SSc after their transition from male-to-female, who presented to our centre. Two additional transgender cases de- scribed in the literature with CTD were included in this review. RESULTS: All three patients developed SSc after having started the hormonal therapy required to transition. Two patients had surgical procedures preceding their diagnosis of SSc. Antibody profile, time of onset and disease features differed among our patients. Hormonal therapies were continued in all patients and they received the standard therapy for SSc. One patient died from complications of her disease. Only two cases describing the development of CTD in transgender patients were identified in the literature and both of these patients were diagnosed with systemic lupus erythematosus (SLE). CONCLUSIONS: This case series suggests that the hormonal modification as part of gender transition may be relevant in development of SSc. No further conclusions can be drawn on the continuation or not of HT.

AB - OBJECTIVES: To explore the inhibitory effect and mechanism of 1,25-dihydroxy vitamin D3 (l,25(OH)2D3) on receptor activator of nuclear factor-kappaB ligand (RANKL) expression in fibroblast-like synoviocytes (FLSs) and osteoclastogenesis induced by interleukin (IL)-22 in patients with rheumatoid arthritis (RA). METHODS: Fibroblast-like synoviocytes from patients with rheumatoid arthritis (RA FLSs) were cultured and stimulated for RANKL expression with IL-22 in the absence or presence of various concentrations of l,25(OH)2D3, and JAK-2 inhibitor or p38 MAPK inhibitor at the optimised time point of IL-22 treatment. The level of RANKL messenger RNA (mRNA) or protein was measured using real-time polymerase chain reaction (RT-PCR) or western blot method. To assess the impact of l,25(OH)2D3 on osteoclastogenesis, isolated monocytes were activated by M-CSF and RANKL or cocultured with FLSs stimulated by IL-22 in the presence or absence of l,25(OH)2D3 and those inhibitors. TRAP-positive cells as differentiated osteoclasts were stained for alkaline phosphatase. RESULTS: FLSs stimulated with IL-22 for 72 hours were used in further experiment because of the highest expression of RANKL at this time point. The expression of RANKL mRNA and protein in IL-22-stimulated FLSs were significantly inhibited by 1 nM of 1,25(OH)2D3 (p<0.05). Interestingly, this inhibition was reversed by inhibitor of JAK-2/STAT 3 or p38 MAPK/NF-kappaB signalling. In monocytes cocultured with IL-22-stimulated FLSs in the presence of exogenous RANKL and M-CSF, 1,25(OH)2D3 could block the process of osteoclastogenesis by JAK-2/STAT-3 or p38 MAPK/NF-kappaB signalling. CONCLUSIONS: 1,25(OH)2D3 may exert inhibitory effect on osteoclastogenesis of RA FLSs by down-regulating RANKL expression, which could be mediated by IL-22 through JAK-2/STAT-3 and p38 MAPK/NF-kappaB signalling.

PMID- 29465365 TI - Polyarteritis nodosa revisited: a review of historical approaches, subphenotypes and a research agenda. AB - Polyarteritis nodosa (PAN) is a rare form of primary systemic vasculitis with heterogeneous presentations, treatments and disease course. Historical approaches to classification and diagnostic terminology are reviewed. Since differentiation of PAN from microscopic polyangiitis (MPA) and other ANCA vasculitides by the Chapel Hill conference statements, and with hepatitis associated PAN defined as a secondary vasculitis, the phenotyping and subclassification of PAN has received little attention. Monogenic disorders similar to PAN have been described (familial Mediterranean fever, Adenosine Deaminase-2 deficiency), and cutaneous PAN and single organ vasculitis, discussed. The overlapping phenotypes between PAN and other primary vasculitic syndromes and subphenotypes within PAN are explored. This work will underpin development of newer treatment regimens and future genetic and related aetiologic studies. PMID- 29465366 TI - Cancer development in Korean patients with ANCA-associated vasculitis: a single centre study. AB - OBJECTIVES: We investigated the incidence rate and type of cancer, and furthermore, estimated the standardised incidence ratios (SIRs) of cancer in patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) in Korea. METHODS: We retrospectively included 150 patients with AAV [81 patients with microscopic polyangiitis (MPA), 38 with granulomatosis with polyangiitis (GPA) and 31 patients with eosinophilic GPA (EGPA)], and reviewed their medical records. We collected demographic, clinical and laboratory data, and reviewed the use of glucocorticoid and immunosuppressive drugs administered until detection of cancer or last visit. We estimated the SIRs of cancer according to totality, gender, age, AAV variants and each type of cancer. RESULTS: The mean age at diagnosis of AAV was 55.2 years and that at last visit was 59.5 years. The mean follow-up duration was 50.7 months. Four of 150 AAV patients had cancer (2.7%), and they got four different types of cancers including gastric cancer, lung cancer, prostate cancer and Non-Hodgkin lymphoma. Two patients exhibited gap-time from AAV to malignancy less than one year, and the rest of them exhibited gap-time of 8 and 6 years, respectively. The overall SIR of cancer in AAV patients was 1.43 (95% confidence interval 0.391, 3.671). The SIRs of cancer based on gender, and age at cancer or last visit, AAV variants and each type of cancer were not significant, either. CONCLUSIONS: The risk of cancer is low in Korean patients with AAV. PMID- 29465367 TI - Proprotein convertase enzyme FURIN is upregulated in primary Sjogren's syndrome. AB - OBJECTIVES: The proprotein convertase enzyme FURIN is a critical regulator of the anti-inflammatory TGFbeta-1 cytokine and peripheral immune tolerance. In T cells, FURIN is co-regulated with IFN-gamma and thus highly expressed in T helper 1 type cells. Previous studies have demonstrated that FURIN is upregulated in inflammatory conditions, including atherosclerosis, rheumatoid arthritis and systemic lupus erythematosus. Here, we evaluated the levels of FURIN in the plasma and peripheral blood mononuclear cells (PBMCs) of patients with primary Sjogren's syndrome (pSS) and in healthy controls. METHODS: FURIN plasma levels were determined by ELISA, and the mRNA expression in PBMCs was quantitated using qPCR. FURIN levels in the plasma were correlated with the clinical and demographic characteristics of the patients. RESULTS: FURIN was found to be significantly upregulated at both the protein and mRNA level in pSS patients compared to healthy controls. In pSS patients, high FURIN protein levels were significantly associated with elevated IFN-gamma levels in the plasma as well as a longer duration of sicca symptoms in the eyes. pSS patients with high FURIN levels in their plasma showed a trend towards lower levels of serum beta-2 microglobulin, ESR and a lower systemic disease activity index ESSDAI. CONCLUSIONS: The proprotein convertase FURIN is significantly upregulated in pSS. Elevated FURIN levels associate with high levels of the Th1 type cytokine IFN gamma and long duration of dry eye symptoms. Patients with high FURIN levels show signs of lower disease activity suggesting that FURIN might have a protective role in pSS. PMID- 29465368 TI - Comparative effectiveness of glucosamine, chondroitin, acetaminophen or celecoxib for the treatment of knee and/or hip osteoarthritis: a network meta-analysis. AB - OBJECTIVES: To compare the efficacies of oral glucosamine, chondroitin, the combination of glucosamine and chondroitin, acetaminophen and celecoxib on the treatment of knee and/or hip osteoarthritis. METHODS: We searched electronic databases including PubMed, Embase, and Cochrane Library and the reference lists of relevant articles published from inception to October 23, 2017. A Bayesian hierarchical random effects model was used to examine the overall effect size among mixed multiple interventions. RESULTS: We identified 61 randomised controlled trials of patients with knee and/or hip osteoarthritis. There was no obvious difference in the results between the traditional meta-analysis and the network meta-analysis. The network meta-analysis demonstrated that celecoxib was most likely the best option (SMD, -0.32 [95% CI, -0.38 to -0.25]) for pain, followed by the combination of glucosamine and chondroitin. For physical function, all interventions were significantly superior to oral placebo except for acetaminophen. In terms of stiffness, glucosamine (SMD, -0.36 [95% CI, -0.67 to -0.06]) and celecoxib (SMD, -0.29 [95% CI, -0.51 to -0.08]) were significantly better compared to placebo. In view of safety, compared to placebo only, celecoxib and acetaminophen presented significant differences. CONCLUSIONS: Given the effectiveness of these non-steroidal anti-inflammatory drugs and symptomatic slow-acting drugs, oral celecoxib is more effective than placebo on relieving pain and improving physical function, followed by the combination of glucosamine and chondroitin. Acetaminophen is likely the least efficacious intervention option. This information, accompanied by the tolerability and economic costs of the included treatments, would be conducive to making decisions for clinicians. PMID- 29465369 TI - Altered gene expression profiles of histone lysine methyltransferases and demethylases in rheumatoid arthritis synovial fibroblasts. AB - OBJECTIVES: Aberrant histone lysine methylation (HKM) has been reported in rheumatoid arthritis (RA) synovial fibroblasts (SFs). As histone lysine methyltransferases (HKMTs) and demethylases (HKDMs) regulate HKM, these enzymes are believed to be dysregulated in RASFs. The aim of this study is to clarify whether gene expressions of HKMTs and HKDMs are altered in RASFs. METHODS: SFs were isolated from synovial tissues obtained from RA or osteoarthritis (OA) patients during total knee joint replacement. The mRNA levels of 34 HKMTs and 22 HKDMs were examined after stimulation with tumour necrosis factor alpha (TNF alpha) in RASFs and OASFs. RESULTS: The gene expression of the 12 HKMTs, including MLL1, MLL3, SUV39H1, SUV39H2, PRDM2, EZH2, SETD2, NSD2, NSD3, SMYD4, DOT1, and PR-set7, that catalyse the methylation of H3K4, H3K9, H3K27, H3K36, H3K79, or H4K20 was higher after TNFalpha stimulation in RASFs vs. OASFs. The gene expression of the 4 HKDMs, including FBXL10, NO66, JMJD2D, and FBXL11, that catalyse the methylation of H3K4, H3K9, or H3K36 was higher after TNFalpha stimulation in RASFs vs. OASFs. CONCLUSIONS: The study findings suggest that the HKM-modifying enzymes are involved in the alteration of HKM, which results in changes in the gene expression of RASFs. PMID- 29465370 TI - The initial predictors of death in 153 patients with ANCA-associated vasculitis in a single Korean centre. AB - OBJECTIVES: We estimated the cumulative patient survival rates, the causes of death and the initial predictors of death in Korean patients with microscopic polyangiitis (MPA), granulomatosis with polyangiitis (GPA) and eosinophilic GPA (EGPA). METHODS: We reviewed the medical records of 153 patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). We collected clinical and laboratory data including ANCA, Birmingham vasculitis activity score (BVAS), five factor score (FFS) (2009), comorbidities, medications and prognosis (death and relapse). The hazard ratio (HR) of variables at diagnosis for death in the disease course was assessed by the Cox hazard model analysis. RESULTS: The mean age of 153 AAV patients (47 men and 106 women) was 55.2 years and the mean follow-up duration was 51.5 months. Fourteen of 153 patients (9.2%) died (7 MPA and 7 GPA patients) during the mean follow-up of 56.9 months. In all patients with AAV, 1 year-, 5 year- and 10 year-cumulative patient survival rates were 96.1%, 94.8% and 92.8%, respectively. The most common cause of death was infection of various causes. FFS (2009) >=2 (HR 16.520, p=0.012) and diffuse alveolar haemorrhage (DAH) (HR 3.705, p=0.042) at diagnosis could predict death during the follow-up in AAV patients in multivariate COX regression analysis. CONCLUSIONS: The overall mortality rate was 9.2% and 10-year cumulative patient survival rate was 92.8%. At diagnosis, FFS (2009) >= 2 and DAH were independent predictors of death during the follow-up in Korean patients with MPA, GPA and EGPA.

PMID- 29465371 TI - Long-term effects of the new direct antiviral agents (DAAs) therapy for HCV related mixed cryoglobulinaemia without renal involvement: a multicentre open label study. AB - OBJECTIVES: To investigate the long-term effects and safety of new direct anti viral agents (DAAs) in patients with hepatitis C virus (HCV)-related mixed cryoglobulinaemia (MC) without renal involvement. METHODS: The study enrolled 22 consecutive patients, 19 received sofosbuvir-based regimen and three patients received other DAAs, individually tailored according to latest guidelines. As of December 2016, the median length of follow-up was 17 months (range 13-21). RESULTS: Extra-hepatic manifestations at enrollment were: purpura and arthralgia (12 cases), peripheral neuropathy (10 cases) and marginal zone B- lymphomas (2 cases). After a four-week DAA therapy, all patients became HCV- negative. Moreover, after 48 weeks since the beginning of DAA treatment, sustained regression of purpura and arthralgias was observed respectively in eight and in nine cases; peripheral neuropathy improved in seven cases, and cryocrit median values decreased from three (1-20) at baseline to two (1-12) after 48 weeks. Two cases with indolent marginal zone lymphomas did not show any haematological response: size and number of the involved nodes remained unchanged. In addition, the monoclonal B-cell population found in the peripheral blood in four cases did not disappear after recovery from HCV- RNA. Mild side effects occurred in nine patients, but six patients developed ribavirin-related anaemia requiring reduction of ribavirin dose. CONCLUSIONS: DAA therapy is safe and effective to eradicate HCV in MC, but seems associated with satisfactory clinical response in mild or moderate cryoglobulinaemic vasculitis and no response in B-NHL. PMID- 29465373 TI - Anti-alpha-enolase antibodies in Behcet's disease: a marker of mucocutaneous and articular disease activity? AB - OBJECTIVES: To assess IgM anti-alpha-enolase antibodies (AAEA) in systemic Behcet's disease (BD) and its possible association with clinical manifestations and disease activity. METHODS: Ninety-seven consecutively selected BD patients were compared to 36 enteropathic spondyloarthritis (ESpA) [24 Crohn's disease (CD) and 12 ulcerative colitis (UC)] patients and 87 healthy controls. IgM AAEA was detected by immunoblotting. Disease activity was assessed by standardised indexes, Brazilian BD Current Activity Form (BR-BDCAF) for BD and Harvey-Bradshaw Index (HBI) for CD and UC patients. A second evaluation was performed in BD patients (n=56), regarding IgM AAEA presence, disease activity scores and C reactive protein (CRP). RESULTS: Higher IgM AAEA prevalence was found in 97 BD (17.7%) compared to ESpA (2.8%) and healthy controls (2.3%), p<0.001. IgM AAEA frequency was higher in active BD compared to inactive BD (30.2% vs. 7.4%, p=0.006), a finding confirmed in the second cross-sectional evaluation of 56 of these BD patients (45.5% vs. 13.3%, p=0.02). Mean BR-BDCAF scores were higher in IgM AAEA positive group on both evaluations (9.1 +/- 5.4 vs. 4.9 +/- 4.9, p=0.002; 5.0 +/- 4.9 vs. 2.2 +/- 2.9, p=0.01, respectively). BD patients with mucocutaneous and articular symptoms presented higher IgM AAEA positivity in the first and second evaluations (64.7% vs. 27.5%, p=0.005; 36.4% vs. 7.1%, p=0.039 respectively). CONCLUSIONS: Our data support the notion that alpha-enolase is a target antigen in BD, particularly associated with disease activity, mucocutaneous and articular involvement. In addition, IgM AAEA may distinguish BD from ESpA, especially in patients with high disease activity. PMID- 29465374 TI - No specific imaging pattern can help differentiate IgG4-related disease from idiopathic retroperitoneal fibrosis: 18 histologically proven cases. AB - OBJECTIVES: Retroperitoneal fibrosis (RPF) is a rare disease, with unknown aetiology (idiopathic RPF: iRPF) in two-thirds of cases. A subset of iRPF may be a manifestation of IgG4-related disease (IgG4-RD). Thus, recognition of IgG4-RD RPF is crucial to optimise patient's care with iRPF. The current study aimed to examine imaging specific patterns, which could help differentiate between IgG4-RD RPF and iRPF, and thus skip performing biopsies. METHODS: This analysis included patients with iRPF and a retroperitoneal biopsy at the Lille University Hospital, France. We reviewed their baseline characteristics, clinical presentation, biological results and imaging features. Patients were classified in 3 groups according to histopathological characteristics of IgG4-RD as follows: highly suggestive of IgG4-RD, possible IgG4-RD, or non-evocative of IgG4-RD. RESULTS: Of the 18 patients analysed in the study, 4 (22%) patients had highly suggestive IgG4-RD-RPF, 8 (44%) possible IgG4-RD-RPF and 6 (33%) non-evocative IgG4-RD. We found no clinical, biological features nor specific imaging pattern that could help differentiate between the 3 groups. CONCLUSIONS: After ruling out all known causes of RPF, retroperitoneal biopsy is still necessary to ascertain the diagnosis of IgG4-RD-RPF. No specific pattern can be used to distinguish between IgG4-RD-RPF and iRFP. PMID- 29465375 TI - Pauci-immune crescentic glomerulonephritis in a patient with B-lymphocyte poly/autoreactivity.

AB - Benzalkonium chloride (BAC), which is a mixture of C8 and C18 alkylbenzyldimethylammonium chlorides, has an important biocide character and is used in many cosmetics, especially wet wipes, as a preservative and/or antibacterial agent. The concentration range of BAC is 0.005-0.5 % and it is an irritant substance when used at high concentrations. Thus, the concentration of BAC should be carefully monitored in commercial products intended for skin use. In this study, a capillary electrophoresis (CE) analysis method for BAC quantification was developed. The quantitative analysis was carried out by the external standard method. The electrophoretic separation was performed by using 75 mM (pH 6.0) phosphate buffer solution containing 30% acetonitrile as the electrolyte. The separation voltage was 10 kV and the temperature was held at 18 degrees C. Samples were introduced into the capillary column hydrodynamically using 50.0-mbar pressure over a 3-s period. The developed method was validated and applied on samples prepared by wringing out antibacterial wet wipes containing BAC without any further extraction. The linearity of the method was controlled by applying the Mandel test. The limit of detection (LOD) values for the developed method were 0.313 and 0.309 ug/ml and the limit of quantification (LOQ) values were 1.042 and 1.029 ug/ml for C10 and C12 derivatives, respectively. PMID- 29465378 TI - Investigation of water-soluble elastin as a multifunctional cosmetic material: Moisturizing and whitening effects. AB - Elastin and collagen are extracellular matrix proteins that are widely distributed in the body. Although elastin essentially functions as a skin moisturizer, there have been few reports on its other fundamental chemical and biological functions. In this study, we investigated the moisturizing and whitening (tyrosinase inhibition) effects of elastin to examine its usefulness as a cosmetic material. Water-soluble hot alkali pig aorta (HAPA)-elastin was prepared from pig aorta using the hot alkali method. HAPA-elastin showed a widely distributed molecular weight and had a coacervation property that mediated reversible self-assembly of its molecules with increasing temperature. Amino acid analysis of HAPA-elastin showed a high content (81.5%) of hydrophobic amino acids such as Gly, Ala, Val, and Pro. Des (desmosine) and Ide (isodesmosine), which are characteristic amino acids of elastin, accounted for more than 0.4% of the total amino acid content. HAPA-elastin showed a moisture-retaining property. The water content of skin samples treated with and without HAPA-elastin was 77.2% +/- 7.8% and 49.4% +/- 10.1%, respectively. HAPA-elastin also inhibited tyrosinase activity by 11.3% +/- 3.9%. The results obtained indicate that elastin has a useful function as a cosmetic material. PMID- 29465379 TI - Effect of SIRT6 knockdown on NF-kappaB induction and on residual DNA damage in cultured human skin fibroblasts. AB - SIRT6 is a member of the sirtuin family, which is involved in multiple cellular pathways related to aging, inflammation, epigenetics, and a variety of other cellular functions, including DNA repair (1). Multiple pathways involving different cellular functions are impacted by the deacetylase activity of SIRT6. Genomic integrity is maintained by the capacity of SIRT6 to modulate the accessibility of DNA repair proteins. Glucose metabolism is suppressed by SIRT6 via the deacetylation of histones located at the promoter regions of multiple glycolytic genes and the corepression of hypoxia-inducible factor-1alpha. SIRT6 is also a corepressor of nuclear factor (NF)-kappaB, silencing NF-kappaB target genes through the deacetylation of histones at their promoters' regions. We used SIRT6 small-interfering RNA as a tool to modulate residual DNA damage and NF kappaB expression in human dermal fibroblasts. We measured NF-kappaB levels in the presence or the absence of ultraviolet B (UVB). The impact of SIRT6 knockdown as shown by a decrease in SIRT6 messenger RNA levels resulted in residual DNA damage as evaluated by the comet assay. Our results show that NF-kappaB was increased significantly (up to 400%) due to SIRT6 silencing in the absence of UVB, illustrating the master regulatory function of SIRT6 in inflammation. We also found a significant increase in DNA damage without UV exposure as a result of SIRT6 silencing, indicating the importance of SIRT6 in DNA repair pathways in cultured human dermal fibroblasts.

AB - Salicylic acid (SA) is widely used in leave-on antiacne formulations, typically at a 2% level. As a beta-hydroxy acid, it is a milder active ingredient than either alpha-hydroxy acids or benzoyl peroxide. SA is a keratolytic agent, a bacteriocide, and a comedolytic agent. For these reasons, improving the efficiency of SA delivery is of interest. The objective of this work is to measure in vivo SA penetration from topically applied 2% SA leave-on products and to understand the penetration in terms of formulation parameters. Penetration of SA was measured in three depth zones-0-3 MUm, 3-6 MUm, and 6-9 MUm below the surface-using in vivo confocal Raman spectroscopy. The delivery of SA from an emulsion, pH 4.0, and a hydrogel, pH 3.75, was compared and contrasted. A comparison of depth profiles reveals, e.g., significant differences in SA distribution between-treatment profiles at various time points after treatment, particularly 3C6 MUm below the surface. The hydrogel exhibited the higher normalized level of SA in the 3-6 MUm depth zone. Confocal in vivo Raman spectroscopy is proving to be a valuable tool in determination of details of penetration of products into the skin. The penetration of various 2% SA anti-acne product forms will be compared and contrasted in this presentation. Delivery of SA will be discussed in terms of formulation parameters such as phase, pH, and specific ingredients and molecular-level interactions. PMID- 29465384 TI - A botanically derived skin surface lipid mimetic based on the composition of healthy 22-year-old females. AB - INTRODUCTION: Skin surface lipids (SSLs) greatly affect the skin physiology and are thought to be involved in skin processes such as thermoregulation, bacterial colonization, and barrier function and maintenance. SSLs are primarily composed of fatty acids, triglycerides, cholesterol, steryl esters, wax esters, and squalene. The objective of this research was to evaluate and better understand the SSL composition and variation in an age- and sex-controlled population, and create an appropriate botanically derived mimetic. METHODS: SSL samples taken from the foreheads of 59 healthy, 22-year-old females were analyzed by gas chromatography mass spectrometry (GC-MS). Using botanically derived raw materials from Macadamia integrifolia, Simmondsia chinensis, and Olea europaea, a mimetic was engineered via a series of esterification reactions and lipid components quantitated with GC-MS. The glyceride and wax ester components were produced by the interesterification of M. integrifolia and S. chinensis under specified conditions. The steryl ester component was produced by the esterification of the fatty acids of M. integrifolia and phytosterols under similar conditions. RESULTS: The following major classes of lipids were found and quantified by percent composition: glycerides, free fatty acids, squalene, wax esters, steryl esters, and cholesterol. The variability between subjects for each component was minimal; however, the greatest variation was seen for free fatty acids and cholesterol. Correlations among the components were calculated and found to be statistically or directionally significant with few exceptions. The esterification reactions of jojoba, macadamia, and tall oils, along with a precise addition of squalene derived from O. europaea, produced a suitable SSL mimetic. When applied to delipidized skin, the mimetic helped restore barrier function, increased skin hydration, and increased skin elasticity and firmness in aged skin. DISCUSSION: The present research indicates that, overall, the SSL composition is quite consistent in a controlled population of 22-year-old females. Furthermore, there were strong correlations between the SSL components among subjects, with the exception of squalene and steryl esters. This was expected due to the fact that of the six major SSL components, steryl esters and squalene also showed higher variation over time for each individual. The variation in free fatty acids may be attributable to the potential differences in the microflora of the subjects. The variation in this study's results, as compared to previously published work, could indicate that the collection methods, geographic location, gender, and age specificity contribute to the distribution or collection of different lipid components on the skin surface. Since the excretion of sebum is known to decrease in females after 40 years of age, the proposed mimetic could be a beneficial supplement to human SSLs in aged skin, as well as in skin where the stratum corneum is defective, by aiding in the restoration of barrier function, while increasing skin hydration, elasticity, and firmness.

For a given formulation chassis, we recommend studying compatibility and viscoelastic profiles of blends made of "Hard" polymeric resins and "Soft" structuring polymers to gain fundamental understanding of the polymer matrix for pigment adhesion. Enhanced oil/sebum resistance may be achieved, where there is good compatibility among the "Soft" and "Hard" polymeric components and where there is considerable immiscibility between oil/sebum and each nonvolatile component. Our strategy may help promote cosmetic formulation development based on rational design and understanding interactions among components, develop novel long-wear formulation chassis, and properly evaluate emerging new technologies.

PMID- 29465391 TI - New targets in the battle against dandruff. AB - Dandruff is a scalp disorder characterized by flaking skin and itch of an excessive oily scalp skin. It affects 55% of the global youth and adult population. Seborrheic dermatitis is a similar scalp skin disorder with aggravated itchy rashes and flaking. Different factors are identified in the dandruff development: increased sebum production, uncontrolled fungal growth of Malassezia strains and individual reaction to pro-inflammatory environment, and the susceptibility to trigger an immunological response. Using in vitro and ex vivo models, we show that an Epilobium angustifolium extract dose dependently reduces lipid synthesis in sebocytes to a maximum of -43% (1% extract), and protects the epidermis from Malassezia-induced morphological changes. Epilobium angustifolium extract also acts through innovative mechanisms involving regulations of defensins (human beta-defensins [hBD2] and hBD3) and toll-like receptor 2 involved in the immunological response of the skin. The anti-dandruff and sebum-regulating efficacy of E. angustifolium extract (1.5%) was confirmed in a clinical study that mobilized 24 volunteers with dandruff and greasy scalp for 30 days. At the end of the study, nonadherent and adherent dandruffs were significantly (p < 0.0001) reduced in average by -54% and -48%, respectively. Using Sebumeter(r) measurements, scalp sebum production was inhibited by -67% (p < 0.0001) in average over baseline. In conclusion, E. angustifolium extract offers a new innovative approach to dandruff reduction through immunomodulation of the skin response to Malassezia invasion.

AB - Structure/property comparisons were made of chemistries based on renewable 1,3 propanediol (PDO)- versus petroleum-based alkylene oxides as well as comparisons of the respective polyethers, emulsifiers, and cosmetic formulations based on these feedstocks. Green Chemistry Principles were applied in the manufacture of polyethylene glycol (PEG)-free renewable PDO-based oligomers and PDO-based fatty acid ester emulsifiers. Sustainable cosmetic products formulated with renewable PDO-based emulsifiers gave equivalent performance in sensory and moisturization evaluations compared to those formulated with the petroleum-derived PEG-based emulsifiers. PMID- 29465393 TI - Unique natural exopolysaccharides for biomimetic protective effect against urban pollution. AB - : Through natural selection, living organisms have evolved well-adapted survival strategies over time. The shallow salt waters of Moorea lagoon are the site of accumulation of microbial mats called "Kopara," in the native Polynesian language. This unique ecosystem is rich in film-forming exopolysaccharides (EPSs) secreted by microorganisms within the biofilm, as a mean to protect themselves from environmental stress (strong ultraviolet [UV], pH, salinity ... ). Using blue biotechnology, a manufacturing process was developed to obtain an EPS with skin benefits. The active ingredient (EPS-229) protects against urban pollution, including free radicals, heavy metals, hydrocarbons, and PM2.5 (particulate matter with a size lower than 2.5 MUm). METHODS: The anti-lipid peroxidation action of EPS-229 was studied in an in vitro UVB-irradiated keratinocyte culture model, using lipophilic fluorescent probe. The chelating properties of EPS-229 were evaluated in tubo in the presence of cadmium and lead. The protective effect of EPS-229 on pollution-exposed skin explants was investigated through quantification of released malondialdehyde (MDA) and histological observation of skin morphology using optical microscopy. Clinical evaluation of the protective and cleansing efficacy of a water solution containing EPS-229 (0.02% and 0.01% w/v, respectively) was performed, against placebo, on a panel of 18 volunteers. For these studies, the forearms of volunteers were treated with EPS-229 before (anti-adhesion affect) or after (cleansing effect) application of PM2.5 (iron particles of 1 MUm). The presence of skin-adherent particles was observed and quantified by image analysis, using specific digital masks. RESULTS: In vitro, EPS-229 significantly protected keratinocyte cell membranes from lipid peroxidation. A decrease of 28% was achieved when a concentration of 0.001% w/v EPS-229 was applied to the cell culture. In tubo, EPS-229 also presented strong chelating properties. Maximal adsorption was estimated at 154 mg/g (1.37 mmol/g) of EPS-299 for cadmium and at 250 mg/g (1.21 mmol/g) of EPS-229 for lead. In the skin explant model of pollution exposure, EPS-229 (0.03% w/v) reduced MDA production by 44%, preserved cell integrity, improved dermal-epidermal cohesion, and normalized the collagen network. In vivo, treatment of skin with EPS-229 before exposure to PM2.5 created a protective film limiting particle adhesion. When used in a cleansing solution after exposure to PM2.5, EPS-229 formed a mesh that entrapped particles and removed them from the skin surface. CONCLUSION: Inspired by the French Polynesia Kopara unique ecosystem, a bioactive exopolysaccharide (EPS-229) has been developed that offers protection from environmental aggression. As a biomimetic shield at the surface of the skin, EPS 229 provides an immediate multiprotective action that efficiently fights the harmful effects of urban pollution and smog.

PMID- 29465396 TI - A dynamic mechanism for allosteric activation of Aurora kinase A by activation loop phosphorylation. AB - Many eukaryotic protein kinases are activated by phosphorylation on a specific conserved residue in the regulatory activation loop, a post-translational modification thought to stabilize the active DFG-In state of the catalytic domain. Here we use a battery of spectroscopic methods that track different catalytic elements of the kinase domain to show that the ~100 fold activation of the mitotic kinase Aurora A (AurA) by phosphorylation occurs without a population shift from the DFG-Out to the DFG-In state, and that the activation loop of the activated kinase remains highly dynamic. Instead, molecular dynamics simulations and electron paramagnetic resonance experiments show that phosphorylation triggers a switch within the DFG-In subpopulation from an autoinhibited DFG-In substate to an active DFG-In substate, leading to catalytic activation. This mechanism raises new questions about the functional role of the DFG-Out state in protein kinases. PMID- 29465398 TI - On the move.

PMID- 29465397 TI - Molecular coordination of Staphylococcus aureus cell division. AB - The bacterial cell wall is essential for viability, but despite its ability to withstand internal turgor must remain dynamic to permit growth and division. Peptidoglycan is the major cell wall structural polymer, whose synthesis requires multiple interacting components. The human pathogen Staphylococcus aureus is a prolate spheroid that divides in three orthogonal planes. Here, we have integrated cellular morphology during division with molecular level resolution imaging of peptidoglycan synthesis and the components responsible. Synthesis occurs across the developing septal surface in a diffuse pattern, a necessity of the observed septal geometry, that is matched by variegated division component distribution. Synthesis continues after septal annulus completion, where the core division component FtsZ remains. The novel molecular level information requires re-evaluation of the growth and division processes leading to a new conceptual model, whereby the cell cycle is expedited by a set of functionally connected but not regularly distributed components. PMID- 29465399 TI - Learning place cells, grid cells and invariances with excitatory and inhibitory plasticity. AB - Neurons in the hippocampus and adjacent brain areas show a large diversity in their tuning to location and head direction, and the underlying circuit mechanisms are not yet resolved. In particular, it is unclear why certain cell types are selective to one spatial variable, but invariant to another. For example, place cells are typically invariant to head direction. We propose that all observed spatial tuning patterns - in both their selectivity and their invariance - arise from the same mechanism: Excitatory and inhibitory synaptic plasticity driven by the spatial tuning statistics of synaptic inputs. Using simulations and a mathematical analysis, we show that combined excitatory and inhibitory plasticity can lead to localized, grid-like or invariant activity. Combinations of different input statistics along different spatial dimensions reproduce all major spatial tuning patterns observed in rodents. Our proposed model is robust to changes in parameters, develops patterns on behavioral timescales and makes distinctive experimental predictions.

PMID- 29465401 TI - Adherence to Anaphylaxis Guidelines: Real-World Data From the Emergency Department of a Tertiary Hospital. AB - BACKGROUND AND OBJECTIVE: Few studies have evaluated adherence to anaphylaxis guidelines in emergency departments (EDs). Objective: The objective of this study was to evaluate adherence to anaphylaxis guidelines in the ED of a tertiary hospital. METHODS: Medical records of patients attended in the ED of University Hospital of Salamanca, Spain were reviewed. Those patients fulfilling the anaphylaxis criteria proposed by the NIAID/FAAN were selected. RESULTS: During a 1-year period, we identified 89 patients (74 adults and 15 children). The anaphylactic reaction was moderate in 65% of adults, severe in 34%, and very severe in 1%. In children, all reactions were moderate. Fewer than half of the patients (42%) received adrenaline in the ED; this was administered intramuscularly in only 19% of cases. As for the severity of the reaction, 65% of patients with moderate reactions and 42% with severe reactions were not treated with adrenaline. At discharge from the ED, an adrenaline auto-injector was recommended to only 5.6% of patients. Fifty-two percent of patients received a documented allergy referral (57% adults vs 27% children, P=.047), 29% instructions about avoidance of triggers (31% adults vs 20% children, NS), and 51% written instructions for recognition of anaphylaxis warning signs (41% adults vs 100% children, P<.001). CONCLUSIONS: The results of the study show a large discrepancy between recommendations in guidelines and management of anaphylaxis in the ED. Additional training efforts are needed to improve the treatment of patients with anaphylactic reactions. PMID- 29465400 TI - Tumor initiating cells induce Cxcr4-mediated infiltration of pro-tumoral macrophages into the brain. AB - It is now clear that microglia and macrophages are present in brain tumors, but whether or how they affect initiation and development of tumors is not known. Exploiting the advantages of the zebrafish (Danio rerio) model, we showed that macrophages and microglia respond immediately upon oncogene activation in the brain. Overexpression of human AKT1 within neural cells of larval zebrafish led to a significant increase in the macrophage and microglia populations. By using a combination of transgenic and mutant zebrafish lines, we showed that this increase was caused by the infiltration of peripheral macrophages into the brain mediated via Sdf1b-Cxcr4b signaling. Intriguingly, confocal live imaging reveals highly dynamic interactions between macrophages/microglia and pre-neoplastic cells, which do not result in phagocytosis of pre-neoplastic cells. Finally, depletion of macrophages and microglia resulted in a significant reduction of oncogenic cell proliferation. Thus, macrophages and microglia show tumor promoting functions already during the earliest stages of the developing tumor microenvironment.

AB - In this work, we investigate the pressure and compressibility factors of bidisperse magnetic fluids with relatively weak dipolar interactions and different granulometric compositions. In order to study these properties, we employ the method of diagram expansion, taking into account two possible scenarios: (1) dipolar particles repel each other as hard spheres; (2) the polymer shell on the surface of the particles is modelled through a soft-sphere approximation. The theoretical predictions of the pressure and compressibility factors of bidisperse ferrofluids at different granulometric compositions are supported by data obtained by means of molecular dynamics computer simulations, which we also carried out for these systems. Both theory and simulations reveal that the pressure and compressibility factors decrease with growing dipolar correlations in the system, namely with an increasing fraction of large particles. We also demonstrate that even if dipolar interactions are too weak for any self-assembly to take place, the interparticle correlations lead to a qualitative change in the behaviour of the compressibility factors when compared to that of non-dipolar spheres, making the dependence monotonic. PMID- 29465410 TI - Mechanistics of biomass discharge during whole-heart decellularization. AB - Whole-organ engineering-based on the functional repopulation of acellular whole organ scaffolds derived from perfusion-based in toto decellularization of the specific organ system-is one of the most promising fields in tissue engineering. However, to date, we still have hardly any insights into the process of perfusion based scaffold generation itself, with human-scale scaffolds usually obtained by adoption of small animal decellularization models, although those organs are of decreased biomass and potentially different biological characteristics. Therefore, in this study we analyzed perfusion-based human-scale whole-heart decellularization by evaluating and comparing the dynamics of biomass discharge and its kinetic characteristics during in toto decellularization of ovine and rodent hearts, while introducing a theoretical model of biomass depletion during perfusion-based whole-heart decellularization. Our results suggest highly varying process characteristics for the in toto decellularization of individual human scale organs, such as protein discharge kinetics or time-dependent viscoelasticity of formed debris, despite seemingly consistent inter-sample decellularization efficacy, as evaluated by conventional disruptive analysis of obtained ECM scaffolds. Hence, the here exposed insights into the mechanistics of whole-heart decellularization as well as the introduced non-disruptive process accompanying tools may help to monitor and further optimize the decellularization process, especially with regards to human-scale scaffold production.

AB - Three-dimensional (3D) cotton-like Ni-Co layered double hydroxide nanosheet arrays/nickel nanowires (3D Ni-Co LDH/NiNw) were successfully fabricated through a facile chemical bath deposition method. The 3D nickel nanowires are used as a conductive substrate with robust adhesion for high-pseudocapacitance Ni-Co LDH. The 3D Ni-Co LDH/NiNw electrode shows a high areal specific capacitance of 14 F cm-2 at 5 mA cm-2 and quality specific capacitance of 466.6 F g-1 at 0.125 A g-1 with respect to the whole quality of the electrode. The fabricated asymmetric supercapacitor exhibits a remarkable energy density of 0.387 mWh cm-2 using Ni-Co LDH/NiNw as the negative electrode. This high-performance composite electrode presents a new and affordable general approach for supercapacitors. PMID- 29465412 TI - Magnetic particle imaging for in vivo blood flow velocity measurements in mice. AB - Magnetic particle imaging (MPI) is a new imaging technology. It is a potential candidate to be used for angiographic purposes, to study perfusion and cell migration. The aim of this work was to measure velocities of the flowing blood in the inferior vena cava of mice, using MPI, and to evaluate it in comparison with magnetic resonance imaging (MRI). A phantom mimicking the flow within the inferior vena cava with velocities of up to 21 cm s-1 was used for the evaluation of the applied analysis techniques. Time-density and distance-density analyses for bolus tracking were performed to calculate flow velocities. These findings were compared with the calibrated velocities set by a flow pump, and it can be concluded that velocities of up to 21 cm s-1 can be measured by MPI. A time density analysis using an arrival time estimation algorithm showed the best agreement with the preset velocities. In vivo measurements were performed in healthy FVB mice (n = 10). MRI experiments were performed using phase contrast (PC) for velocity mapping. For MPI measurements, a standardized injection of a superparamagnetic iron oxide tracer was applied. In vivo MPI data were evaluated by a time-density analysis and compared to PC MRI. A Bland-Altman analysis revealed good agreement between the in vivo velocities acquired by MRI of 4.0 +/ 1.5 cm s-1 and those measured by MPI of 4.8 +/- 1.1 cm s-1. Magnetic particle imaging is a new tool with which to measure and quantify flow velocities. It is fast, radiation-free, and produces 3D images. It therefore offers the potential for vascular imaging. PMID- 29465413 TI - Facile synthesis of nickel-doped Co9S8 hollow nanoparticles with large surface controlled pseudocapacitive and fast sodium storage. AB - Transition metal sulfides are considered to be promising candidates as anodes for sodium ion batteries (SIBs). However, their further applications are limited by poor electrical conductivity and sluggish electrochemical kinetics. We report, for the first time, nickel-doped Co9S8 hollow nanoparticles as SIB anodes with enhanced electrical conductivity and a large pseudocapacitive effect, leading to fast kinetics. This compound exhibits excellent sodium storage performance, including a high capacity of 556.7 mA h g-1, a high rate capability of 2000 mA g 1 and an excellent stability up to 200 cycles. The results demonstrate that nickel-doped Co9S8 hollow nanoparticles are a promising anode material for SIBs. PMID- 29465414 TI - Septal penetration correction in I-131 imaging following thyroid cancer treatment. AB - Whole body gamma camera images acquired after I-131 treatment for thyroid cancer can suffer from collimator septal penetration artefacts because of the high energy of the gamma photons. This results in the appearance of 'spoke' artefacts, emanating from regions of high activity concentration, caused by the non isotropic attenuation of the collimator. Deconvolution has the potential to reduce such artefacts, by taking into account the non-Gaussian point-spread function (PSF) of the system. A Richardson-Lucy deconvolution algorithm, with and without prior scatter-correction was tested as a method of reducing septal penetration in planar gamma camera images. Phantom images (hot spheres within a warm background) were acquired and deconvolution using a measured PSF was applied. The results were evaluated through region-of-interest and line profile analysis to determine the success of artefact reduction and the optimal number of deconvolution iterations and damping parameter (lambda). Without scatter correction, the optimal results were obtained with 15 iterations and lambda = 0.01, with the counts in the spokes reduced to 20% of the original value, indicating a substantial decrease in their prominence. When a triple-energy window scatter-correction was applied prior to deconvolution, the optimal results were obtained with six iterations and lambda = 0.02, which reduced the spoke counts to 3% of the original value. The prior application of scatter-correction therefore produced the best results, with a marked change in the appearance of the images. The optimal settings were then applied to six patient datasets, to demonstrate its utility in the clinical setting. In all datasets, spoke artefacts were substantially reduced after the application of scatter-correction and deconvolution, with the mean spoke count being reduced to 10% of the original value. This indicates that deconvolution is a promising technique for septal penetration artefact reduction that could potentially improve the diagnostic accuracy of I-131 imaging. Novelty and significance This work has demonstrated that scatter correction combined with deconvolution can be used to substantially reduce the appearance of septal penetration artefacts in I-131 phantom and patient gamma camera planar images, enable improved visualisation of the I-131 distribution. Deconvolution with symmetric PSF has previously been used to reduce artefacts in gamma camera images however this work details the novel use of an asymmetric PSF to remove the angularly dependent septal penetration artefacts. PMID- 29465415 TI - Dose coefficients for children and young adolescents exposed to external neutron fields. AB - The risks associated with exposure to external fields of ionising radiation are important to quantify in order to provide guidance towards public and worker protection. In Publication 116 of 2010, the International Commission on Radiological Protection (ICRP) published adult male and female fluence-to-dose coefficients (henceforth referred to as dose coefficients) for external exposures to six types of idealised neutron fields. However, ICRP 116 dose coefficients are not appropriate for applications involving children due to their smaller body weight and stature. Our current work details dose coefficient calculations for children and young adolescents using the UF-NCI pediatric hybrid phantoms at all neutron energies considered in ICRP 116 (0.001 eV to 10 GeV); those dose coefficients with energy up to 150 MeV are discussed. The hybrid UF-NCI phantoms are divided into five separate age groups: newborn, 1, 5, 10, and 15 years. For these phantoms, we calculated dose coefficients for the six idealised neutron fields for 28 organs, two bone tissues, and the overall whole body effective dose. All calculations were performed using the MCNP6 radiation transport code. To validate our methodology, we first calculated dose coefficients for the ICRP adult male and female phantoms and confirmed our ability to reproduce the values published within ICRP 116. The same methodology was then applied to calculate dose coefficients for the UF-NCI pediatric phantoms. Energy-dependent trends were observed in the neutron dose coefficients for pediatric phantoms: below 100 keV, dose increases with phantom age (a proxy for body size); however, above 100 keV, the opposite trend was observed. Comparisons between field geometries showed varying trends depending on the location of the organ within the body. Explanations for these trends are also explored within. Our results are the first comprehensive set of neutron dose coefficients derived for children and young adolescents using the newest generation of hybrid phantoms. The primary application of the pediatric neutron dose coefficients presented in this work will be for a planned effort to update the dosimetry for the Japanese atomic bomb survivors. PMID- 29465416 TI - Ammonium-tungstate-promoted growth of boron nitride nanotubes. AB - Ammonium tungstate ((NH4)10W12O41 . xH2O) is a kind of oxygen-containing ammonium salt. The following study proves that it can be successfully used as a metal oxide alternative to produce boron oxide (B2O2) by oxidizing boron (B) in a traditional boron oxide chemical vapor deposition (BOCVD) process. This special oxidant promotes the simplistic fabrication of boron nitride nanotubes (BNNTs) in a conventional horizontal tube furnace, an outcome which may have resulted from its strong oxidizability. The experimental results demonstrate that the mole ratio of B and (NH4)10W12O41 . xH2O is a key parameter in determining the formation, quality and quantity of BNNTs when stainless steel is employed as a catalyst. We also found that Mg(NO3)2 and MgO nanoparticles (NPs) can be used as catalysts to grow BNNTs with the same precursor. The BNNTs obtained from the Mg(NO3)2 catalyst were straighter than those obtained from the MgO NP catalyst. This could have been due to the different physical forms of the catalysts that were used. PMID- 29465417 TI - Effect of distribution, interface property and density of hydrogel-embedded vertically aligned carbon nanotube arrays on the properties of a flexible solid state supercapacitor. AB - In this paper we fabricate a robust flexible solid-state supercapacitor (FSC) device by embedding a conductive poly(vinyl alcohol) hydrogel into aligned carbon nanotube (CNT) arrays. We carefully investigate the effect of distribution, interface properties and densification of CNTs in the gel matrix on the electrochemical properties of an FSC. The total electrochemical capacitance of the device is measured to be 227 mF cm-3 with a maximum energy density of 0.02 mWh cm-3, which is dramatically enhanced compared with a similar device composed of non-parallel CNTs. Additionally, controllable in situ electrochemical oxidation greatly improved the compatibility between the hydrophobic CNTs and the hydrophilic hydrogel, which decreased the resistance of the device and introduced extra pseudocapacitance. After such oxidation treatment the energy storage ability further doubled to 430 mF cm-3 with a maximum energy density of 0.04 mWh cm-3 . The FSCs based on densified CNT arrays exhibited a much higher volumetric capacitance of 1140 mF cm-3 and a larger energy density of 0.1 mWh cm-3, with a large power density of 14 mW cm-3. All devices show excellent stability of capacitance after at least 10 000 charge-discharge cycles with a loss of less than 2%. These easy-to-assemble hybrid arrays thus potentially provide a new method for manufacturing wearable devices and implantable medical devices. PMID- 29465418 TI - Distinguishing Majorana bound states and Andreev bound states with microwave spectra. AB - Majorana fermions are a fascinating and not yet confirmed quasiparticles in condensed matter physics. Here we propose using microwave spectra to distinguish Majorana bound states (MBSs) from topological trivial Andreev bound states. By numerically calculating the transmission and Zeeman field dependence of the many body excitation spectrum of a 1D Josephson junction, we find that the two kinds of bound states have distinct responses to variations in the related parameters. Furthermore, the singular behaviors of the MBSs spectrum could be attributed to the robust fractional Josephson coupling and nonlocality of MBSs. Our results provide a feasible method to verify the existence of MBSs and could accelerate its application to topological quantum computation. PMID- 29465419 TI - Assessment of PCXMC for patients with different body size in chest and abdominal x ray examinations: a Monte Carlo simulation study. AB - A PC Program for x ray Monte Carlo (PCXMC) has been used to calculate organ doses in patient dosimetry and for the exposure assessment in epidemiological studies of radiogenic health related risks. This study compared the dosimetry from using the built-in stylized phantoms in the PCXMC to that of a newer hybrid phantom library with improved anatomical realism. We simulated chest and abdominal x ray projections for 146 unique body size computational phantoms, 77 males and 69 females, with different combinations of height (125-180 cm) and weight (20-140 kg) using the built-in stylized phantoms in the PCXMC version 2.0.1.4 and the hybrid phantom library using the Monte Carlo N-particle eXtended transport code 2.7 (MCNPX). Unfortunately, it was not possible to incorporate the hybrid phantom library into the PCXMC. We compared 14 organ doses, including dose to the active bone marrow, to evaluate differences between the built-in stylized phantoms in the PCXMC and the hybrid phantoms (Cristy and Eckerman 1987 Technical Report ORNL/TM-8381/V1, Oak Ridge National Laboratory, Eckerman and Ryman 1993 Technical Report 12 Oak Ridge, TN, Geyer et al 2014 Phys. Med. Biol. 59 5225-42). On average, organ doses calculated using the built-in stylized phantoms in the PCXMC were greater when compared to the hybrid phantoms. This is most prominent in AP abdominal exams by an average factor of 2.4-, 2.8-, and 2.8-fold for the 10-year old, 15-year-old, and adult phantoms, respectively. For chest exams, organ doses are greater by an average factor of 1.1-, 1.4-, and 1.2-fold for the 10-year-old, 15-year-old, and adult phantoms, respectively. The PCXMX, due to its ease of use, is often selected to support dosimetry in epidemiological studies; however, it uses simplified models of the human anatomy that fail to account for variations in body morphometry for increasing weight. For epidemiological studies that use PCXMC dosimetry, associations between radiation-related disease risks and organ doses may be underestimated, and to a greater degree in pediatric, especially obese pediatric, compared to adult patients.

PMID- 29465421 TI - Molecular and Metabolic Basis of Clear Cell Carcinoma of the Kidney. AB - Renal cell carcinoma (RCC) is a heterogenous group of tumors, >70% of which belong to the category of clear cell carcinoma. In recent years, crucial advances have been made in our understanding of the molecular and metabolic basis of clear cell carcinoma. This tumor manifests significant alterations in the cellular metabolism, so that the tumor cells preferentially induce the hypoxia response pathway using aerobic glycolysis, rather than the normal oxidative phosphorylation for energy. Most of the clear cell carcinomas (sporadic as well as familial) have mutations and deletions in the VHL gene located at 3p (p3.25). Normally, pVHL plays a crucial role in the proteasomal degradation of hypoxia inducible factors (HIF)1 and HIF2. Lack of a functioning pVHL owing to genetic alterations results in stabilization and accumulation of these factors, which promotes cell growth, cell proliferation, and angiogenesis, contributing to a neoplastic phenotype. Several other genes normally located adjacent to VHL (BAP1, SETD2, PBRM1) may also be lost. These are tumor suppressor genes whose loss not only plays a role in carcinogenesis but may also influence the clinical course of these neoplasms. In addition, interaction among a variety of other genes located at several different chromosomes may also play a role in the genesis and progression of clear cell carcinoma. PMID- 29465422 TI - Elevated Postmortem Vitreous Sodium and Chloride Level in a Salt Water Drowning Death During Self-Contained Underwater Breathing Apparatus Diving With Diving Mask in Place: Case Report. AB - Elevation of postmortem vitreous sodium and chloride (PMVSC) levels in salt water drowning (SWD) is hypothesized to result from electrolyte changes in blood from salt water inhalation/ingestion during drowning. After approximately 1 hour after death, electrolytes may diffuse into the vitreous humor via the eye coverings. This hypothesis was based on a study where bovine eyeballs were immersed in salt water. There is no human study that could confirm that SWD would result in an initial elevation of PMVSC with no effects from immersion. We present an SWD during self-contained underwater breathing apparatus diving in which the face mask remained in its correct position while the deceased was underwater. The face mask would have prevented the orbits from being in direct contact with salt water and therefore stopped any effects of immersion on PMVSC. The PMVSC was 294 mmol/L, above control levels, and the reported cut-off of 259 mmol/L for a diagnosis SWD. The elevated PMVSC would unlikely be owing to immersion but SWD. This case report supports the observation that during SWD PMVSC would initially increase from salt water inhalation and ingestion and not from immersion. PMID- 29465423 TI - Patient Perceptions of Minimally Invasive Versus Open Spine Surgery. AB - STUDY DESIGN: Prospective questionnaire. OBJECTIVE: To describe patient perceptions of minimally invasive spine (MIS) versus open surgery, and to determine which factors are most heavily considered by the patient when choosing between approaches. SUMMARY OF BACKGROUND DATA: MIS surgery has increased in popularity due to proposed advantages in the perioperative and immediate postoperative periods. However, patient preferences and understanding with regard to the differences between MIS and open surgery have not been elucidated. MATERIALS AND METHODS: An anonymous questionnaire consisting of 30 questions was administered to patients scheduled to see either an MIS surgeon or an open spine surgeon for a clinical evaluation from 2016 to 2017. Six questions asked about patient demographics and medical history. Nine questions asked respondents to rate the importance of several criteria when deciding between MIS and open surgery. In total, 15 multiple choice and free response questions asked respondents about their perceptions of MIS versus open surgery with regard to surgical and physician characteristics. RESULTS: In total, 326 patients completed the survey. The 3 most important criteria for patients when choosing between open and MIS surgery were: long-term outcomes, surgeon's recommendation, and complication risk. When compared with MIS surgery, the majority of patients perceived open surgery to be more painful (83.8%), have increased complication risk (78.5%), have increased recovery time (89.3%), have increased costs (68.1%), and require heavier sedation (62.6%). If required to have spine surgery in the future, the majority of both patient groups would prefer a minimally invasive approach (80.0%). CONCLUSIONS: Long-term outcomes, surgeon's recommendation, and complication risk were the most important criteria identified by patients when choosing between open and MIS surgery. Patients also perceived MIS surgery to have advantages over open surgery with regard to postoperative pain, complication risk, recovery time, cost, and anesthesia requirement. Most patients seem to prefer a minimally invasive approach to their treatment. PMID- 29465424 TI - Nutritional approach to preeclampsia prevention. AB - PURPOSE OF REVIEW: Although not fully understood, the physiopathology of preeclampsia is thought to involve an abnormal placentation, diffuse endothelial cell dysfunction and increased systemic inflammation. As micronutrients play a key role in placental endothelial function, oxidative stress and expression of angiogenic factors, periconceptional micronutrient supplementation has been proposed to reduce the risk of preeclampsia. However, recent studies reported conflicting results. RECENT FINDINGS: Calcium intake (>1 g/day) may reduce the risk of preeclampsia in women with low-calcium diet. Data from recently updated Cochrane reviews did not support routine supplementation of vitamins C, E or D for either the prevention or treatment of preeclampsia. Evidences are also poor to support zinc or folic acid supplementation for preeclampsia prevention. Dark chocolate, flavonoid-rich food, and long-chain polyunsaturated fatty acids might also be candidates for prevention of preeclampsia. SUMMARY: Through antioxidant, anti-inflammatory or vasoactive proprieties, micronutrients are good candidates for preeclampsia prevention. Calcium supplementation is recommended to prevent preeclampsia in women with low-calcium intake. Despite positive clinical and in vitro data, strong evidence to support periconceptional supplementation of other micronutrients for preeclampsia risk-reduction is still lacking. Further studies are also needed to evaluate the benefit of nutritional supplementation such as chocolate and long-chain polyunsaturated fatty acids. PMID- 29465425 TI - Optimization of nutrition during allogeneic hematologic stem cell transplantation. AB - PURPOSE OF REVIEW: Malnutrition before and during hematopoietic stem cell transplantation (HSCT) is an independent risk factor for mortality in patients undergoing hematopoietic stem cell transplantation. Yet, optimal use of nutritional support to improve outcomes remains controversial. Our aim was to do an up-to-date literature review regarding nutritional therapy in allogeneic HSCT, the neutropenic diet and the use of immunonutrients. RECENT FINDINGS: Several observational studies find malnutrition to be associated with poor outcome, increased complications and lower overall survival. There are, however, few interventional trials proving the benefits of nutritional therapy in this population compared with no nutritional treatment. Regarding routes of treatment, studies suggested that parenteral nutrition is associated with higher risk for complications compared with enteral nutrition. Whether the use of specific formulas, such as immunonutrition, has a beneficial effect on clinical outcome is not established yet. Strict use of neutropenic diets did not show a reduction in infection risk and clinical outcome, and can no longer be recommended. SUMMARY: Our updated search confirms that malnutrition is a strong negative predictor for outcome, yet optimal use of nutritional interventions to prevent or treat malnutrition remains ill-defined. There is need for larger randomized trials to better address these issues in the future. PMID- 29465426 TI - Advances in molecular diagnosis and therapeutics in nephrotic syndrome and focal and segmental glomerulosclerosis. AB - PURPOSE OF REVIEW: The widespread adoption of next-generation sequencing by research and clinical laboratories has begun to uncover the previously unknown genetic basis of many diseases. In nephrology, one of the best examples of this is seen in focal and segmental glomerulosclerosis (FSGS) and nephrotic syndrome. We review advances made in 2017 as a result of human and molecular genetic studies as it relates to FSGS and nephrotic syndrome. RECENT FINDINGS: There are more than 50 monogenic genes described in steroid-resistant nephrotic syndrome and FSGS, with seven reported in 2017. In individuals presenting with FSGS or nephrotic syndrome before or at the age of 18 years, the commonest genes in which a mutation is found continues to be limited to only a few including NPHS1 and NPHS2 based on multiple studies. For FSGS or nephrotic syndrome that presents after 18 years, mutations in COl4A3/4/5, traditionally associated with Alport syndrome, are increasingly being reported. Despite the extensive genetic heterogeneity in FSGS, there is evidence that some of these genes converge onto common pathways. There are also reports of in-vivo models exploring apolipoprotein 1 biology, variants in which account for part of the increased risk of nondiabetic kidney disease in African-Americans. Finally, genetic testing has several clinical uses including clarification of diagnosis and treatment; identification of suitable young biologic relatives for kidney donation; and preimplantation genetic diagnosis. CRISPR gene editing is currently an experimental tool only, but the recent reports of excising mutations in embryos could be a therapeutic option for individuals with any monogenic disorder in the future. SUMMARY: Sequencing efforts are bringing novel variants into investigation and directing the efforts to understand how these lead to disease phenotypes. Expanding our understanding of the genetic basis of health and disease processes is the necessary first step to elaborate the repertoire of therapeutic agents available for patients with FSGS and nephrotic syndrome. PMID- 29465427 TI - Dihydrotestosterone and cancer risk. AB - PURPOSE OF REVIEW: Androgens have been implicated in prostate growth; however, the role of androgens in prostate cancer development is not clear. Furthermore, studies suggest a role for androgens in female-hormone-dependent cancers and common nonhormone dependent cancers. This study aims to review key studies and more recent studies of dihydrotestosterone (DHT) and cancer risk. RECENT FINDINGS: Epidemiological studies are reassuring as they have not associated endogenous androgens with prostate cancer risk. Intraprostatic regulation of DHT is becoming recognized as an important area of research to clarify the role of DHT in prostate cancer development. In females, further understanding of intracrine regulation of sex hormones and interactions between androgens and estrogens in influencing breast and endometrial cancer risk are required. Studies show a signal for DHT in modulating lung and colorectal cancer growth; however, research in this area is relatively scarce and further studies are required to clarify these associations. SUMMARY: Although concerns of prostate cancer risk remain, there is also potential for androgens to modulate the growth and development of other common cancers. Further research is required as this may have clinical implications. PMID- 29465428 TI - Recent advances in radiation oncology: multimodal targeting of high risk and recurrent prostate cancer. AB - PURPOSE OF REVIEW: The overview summarizes recent developments in radiation oncology for high risk and recurrent prostate cancer. RECENT FINDINGS: A number of well known phase III prostate hypofractionated radiation therapy (HFxRT) trials were finally published with long-term follow-ups. These trials demonstrate patterns of equivalent tumor control with several showing worse toxicity rates. The ASCENDE-RT randomized trial demonstrated the superiority of brachytherapy boost in intermediate and high-risk prostate cancer. Important randomized trials show a clear benefit to androgen deprivation therapy (ADT) in both intermediate risk prostate cancer and postprostatectomy patients with rising PSA. Finally, the first randomized trial of metastasis-directed therapy showed a delay in time to ADT and biochemical failures in oligometastatic prostate cancer. SUMMARY: The use of brachytherapy boost in high-risk disease and ADT in locally recurrent cancer after prostatectomy are practice changing given the magnitude of benefit seen in the randomized trials. The benefit of metastasis-directed therapy in oligometastatic prostate cancer must be validated in a larger randomized trial. However, hypofractionated radiation therapy requires further long-term follow-up so that late toxicity risk can be accurately assessed before it becomes a standard of care in prostate cancer. PMID- 29465430 TI - New paradigms for organ allocation and distribution in liver transplantation. AB - PURPOSE OF REVIEW: The 'Final Rule,' issued by the Health Resources and Service Administration in 2000, mandated that liver allocation policy should be based on disease severity and probability of death, and - among other factors - should be independent of a candidate's residence or listing. As a result, the Organ Procurement Transplantation Network/United Network for Organ Sharing (UNOS) has explored policy changes addressing geographic disparities without compromising outcomes. RECENT FINDINGS: Major paradigm shifts are underway in U.S. liver allocation policy. New hepatocellular carcinoma exception policy incorporates tumor characteristics associated with posttransplantation outcomes, whereas a National Liver Review Board will promote a standardized process for awarding exception points. Meanwhile, following extensive debate, new allocation policy aims to reduce geographic disparity by broadening sharing to the UNOS region and 150-mile circle around the donor hospital for liver transplant candidates with a calculated model for end-stage liver disease score at least 32. Unnecessary organ travel will be reduced by granting 3 'proximity points' to candidates within the same donation service area (DSA) as a liver donor or within 150 nautical miles of the donor hospital, regardless of DSA or UNOS region. SUMMARY: This review provides an evaluation of major policy changes in liver allocation from 2016 to 2018. PMID- 29465429 TI - Advances in prostate-specific membrane antigen PET of prostate cancer. AB - PURPOSE OF REVIEW: In recent years, a large number of reports have been published on prostate-specific membrane antigen (PSMA)/PET in prostate cancer (PCa). This review highlights advances in PSMA PET in PCa during the past year. RECENT FINDINGS: PSMA PET/computed tomography (CT) is useful in detection of biochemical recurrence, especially at low prostate-specific antigen (PSA) values. The detection rate of PSMA PET is influenced by PSA level. For primary PCa, PSMA PET/CT shows promise for tumour localization in the prostate, especially in combination with multiparametric MRI (mpMRI). For primary staging, PSMA PET/CT can be used in intermediate and high-risk PCa. Intraoperative PSMA radioligand guidance seems promising for detection of malignant lymph nodes. While the use of PSMA PET/MRI in primary localized disease is limited to high and intermediate risk patients and localized staging, in the recurrence setting, PET/MRI can be particularly helpful when the lesions are subtle. PSMA PET/CT is superior to choline PET/CT and other conventional imaging modalities. SUMMARY: Molecular imaging with PSMA PET continues to pave the way for personalized medicine in PCa.However, large prospective clinical studies are still needed to fully evaluate the role of PSMA PET/CT and PET/MRI in the clinical workflow of PCa. PMID- 29465431 TI - Noncirrhotic portal hypertension. AB - PURPOSE OF REVIEW: Noncirrhotic portal hypertension represents a heterogeneous group of liver disorders that is characterized by portal hypertension in the absence of cirrhosis. The purpose of this review is to serve as a guide on how to approach a patient with noncirrhotic portal hypertension with a focus on recent developments. RECENT FINDINGS: Recent studies pertaining to noncirrhotic portal hypertension have investigated aetiological causes, mechanisms of disease, noninvasive diagnostic modalities, clinical characteristics in the paediatric population and novel treatment targets. SUMMARY: Noncirrhotic portal hypertension is an underappreciated clinical entity that can be difficult to diagnosis without a healthy suspicion. Diagnosis then relies on a comprehensive understanding of the causes and clinical manifestations of this disease, as well as a careful interpretation of the liver biopsy. Noninvasive approaches to diagnosis may play a significant role moving forward in this disease. Treatment in NCPH remains largely targeted at the individual sequalae of portal hypertension. PMID- 29465433 TI - Emerging targets for reprograming the immune response to promote repair and recovery of function after spinal cord injury. AB - PURPOSE OF REVIEW: In adult mammals, a traumatic spinal cord injury (SCI) elicits a chronic unregulated neuroinflammatory response accompanied by seemingly paradoxical suppression of systemic immunity. These SCI-induced changes in immune function contribute to poor neurological outcomes and enhanced morbidity or mortality. Nonspecific anti-inflammatory or proinflammatory therapies are ineffective and can even worsen outcomes. Therefore, recent experimental SCI research has advanced the understanding of how neuroimmune cross-talk contributes to spinal cord and systemic pathology. RECENT FINDINGS: It is now appreciated that the immune response caused by injury to the brain or spinal cord encompasses heterogeneous elements that can drive events on the spectrum between exacerbating pathology and promoting tissue repair, within the spinal cord and throughout the body. Recent novel discoveries regarding the role and regulation of soluble factors, monocytes/macrophages, microRNAs, lymphocytes and systemic immune function are highlighted in this review. SUMMARY: A more nuanced understanding of how the immune system responds and reacts to nervous system injury will present an array of novel therapeutic opportunities for clinical SCI and other forms of neurotrauma. PMID- 29465434 TI - The Five-Year Clinical and Angiographic Follow-Up Outcomes of Intracoronary Transfusion of Circulation-Derived CD34+ Cells for Patients With End-Stage Diffuse Coronary Artery Disease Unsuitable for Coronary Intervention-Phase I Clinical Trial. AB - OBJECTIVES: This study investigated the clinical and angiographic long-term outcomes of intracoronary transfusion of circulation-derived CD34+ cells for patients with end-stage diffuse coronary artery disease unsuitable for coronary intervention. DESIGN AND SETTING: A single-center prospective randomized double blinded phase I clinical trial. Thirty-eight patients undergoing CD34+ cell therapy were allocated into groups 1 (1.0 * 10 cells/each vessel; n = 18) and 2 (3.0 * 10 cells/each vessel; n = 20). PATIENTS: Those with end-stage diffuse coronary artery disease were unsuitable for percutaneous and surgical coronary revascularization. INTERVENTIONS: Intracoronary delivery of circulation-derived CD34+ cells. MEASUREMENTS AND MAIN RESULTS: We prospectively evaluated long-term clinical and echocardiographic/angiographic outcomes between survivors and nonsurvivors. By the end of 5-year follow-up, the survival rate and major adverse cardio/cerebrovascular event were 78.9% (30/38) and 36.8% (14/38), respectively. During follow-up period, 31.6% patients (12/38) received coronary stenting for reason of sufficient target vessel size grown-up after the treatment. Endothelial function was significantly reduced in the nonsurvivors than the survivors (p = 0.039). Wimasis image analysis of angiographic findings showed that the angiogenesis was significantly and progressively increased from baseline to 1 and 5 years (all p < 0.001). The 3D echocardiography showed left ventricular ejection fraction increased from baseline to 1 year and then remained stable up to 5 years, whereas left ventricular chamber diameter exhibited an opposite pattern to left ventricular ejection fraction among the survivors. The clinical scores for angina and heart failure were significantly progressively reduced from baseline to 1 and 5 years (all p < 0.001). CONCLUSIONS: CD34+ cell therapy for end-stage diffuse coronary artery disease patients might contribute to persistently long term effects on improvement of left ventricular function, angina/heart failure, and amelioration of left ventricular remodeling. PMID- 29465435 TI - Clinical manifestations of sickle cell disease in India: misconceptions and reality. AB - PURPOSE OF REVIEW: In the past, milder clinical manifestations of sickle cell disease (SCD) have been described from India. However, recent data from some parts of India suggest that the severity of the disease can be compared to that of African phenotypes. This review therefore describes the varied clinical manifestation of SCD, the success of newborn screening programme, prenatal diagnosis and low dose hydroxyurea therapy in India. RECENT FINDINGS: The varied clinical manifestations such as anemia, vaso-occlusive crisis, acute chest syndrome, renal involvement, stroke and so on vary from one part of the country to the other and also among different communities of India. Strategies for improving quality of life and controlling of SCD have been suggested. Certain factors other than genetics also play an important role in clinical manifestation of the disorder. SUMMARY: The clinical diversity of SCD is described. The natural history of SCD in India is unfolding from newborn screening programme. The use of low-dose hydroxy urea therapy both in adults and children has brought down the incidences of crisis and provides great relief to the patients. The tailor-made programme for India as regards the control and management has been discussed. PMID- 29465432 TI - Mechanisms for lesion localization in neuromyelitis optica spectrum disorders. AB - PURPOSE OF REVIEW: Neuromyelitis optica spectrum disorders (NMOSD) are severe inflammatory diseases of the central nervous system (CNS), with the presence of aquaporin 4 (AQP4)-specific serum antibodies in the vast majority of patients, and with the presence of myelin oligodendrocyte glycoprotein (MOG)-specific antibodies in approximately 40% of all AQP4-antibody negative NMOSD patients. Despite differences in antigen recognition, the preferred sites of lesions are similar in both groups of patients: They localize to the spinal cord and to the anterior visual pathway including retina, optic nerves, chiasm, and optic tracts, and - to lesser extent - also to certain predilection sites in the brain. RECENT FINDINGS: The involvement of T cells in the formation of NMOSD lesions has been challenged for quite some time. However, several recent findings demonstrate the key role of T cells for lesion formation and localization. Studies on the evolution of lesions in the spinal cord of NMOSD patients revealed a striking similarity of early NMOSD lesions with those observed in corresponding T-cell induced animal models, both in lesion formation and in lesion localization. Studies on retinal abnormalities in NMOSD patients and corresponding animals revealed the importance of T cells for the very early stages of retinal lesions which eventually culminate in damage to Muller cells and to the retinal nerve fiber layer. Finally, a study on cerebrospinal fluid (CSF) barrier pathology demonstrated that NMOSD immunopathology extends beyond perivascular astrocytic foot processes to include the pia, the ependyma, and the choroid plexus, and that diffusion of antibodies from the CSF could further influence lesion formation in NMOSD patients. SUMMARY: The pathological changes observed in AQP4-antibody positive and MOG-antibody positive NMOSD patients are strikingly similar to those found in corresponding animal models, and many mechanisms which determine lesion localization in experimental animals seem to closely reflect the human situation. PMID- 29465436 TI - Orbital exenteration for sinonasal malignancies: indications, rehabilitation and oncologic outcomes. AB - PURPOSE OF REVIEW: Review the recent literature regarding the management of orbital invasion in sinonasal malignant tumors. RECENT FINDINGS: There is a recent trend in preserving the orbit in cases of minimal invasion of periosteum and limited periorbit involvement, as well as in presence of good response to neoadjuvant chemotherapy, mainly in squamous cell carcinoma and neuroendocrine histologies. SUMMARY: The decision about orbital exenteration in cases of sinonasal malignancies is facilitated if the patient already has clear clinical signs of intraconal invasion such as visual loss, restriction of ocular mobility or infiltration of the eyeglobe. However, in borderline situations, confirmation of orbital involvement should be performed intraoperatively. In selected cases with minimal orbital invasion without functional compromise, orbit sparing surgery can be done with acceptable oncological outcomes. PMID- 29465437 TI - Perspectives on voice treatment for unilateral vocal fold paralysis. AB - PURPOSE OF REVIEW: Unilateral vocal fold paralysis (UVFP) is a common cause of neurogenic dysphonia resulting in glottal insufficiency. To restore glottal sufficiency and reduce the presenting dysphonia, treatment involving either surgical intervention, voice therapy or a combination of the two is typically provided. Currently, there is no consensus for the most effective voice treatment for UVFP. This results in an inability to compare current studies, and a lack of treatment effectiveness for the management of UVFP. This study aims to review the most recent literature for the management of dysphonia due to UVFP to establish the current evidence base for voice treatment options. RECENT FINDINGS: There was found to be a lack of consistency in the rationale, selection and timing of the surgical intervention and/or voice therapy being provided for patients with UVFP. SUMMARY: Further consensus is required for the rationale and selection of voice treatment prescriptions for the management of UVFP in order to improve treatment effectiveness and voice outcomes in patients with UVFP. PMID- 29465438 TI - The evolving role of percutaneous ventricular assist devices in high-risk cardiac patients. AB - The Impella is a mechanical circulatory support device that supports ventricular function. Since 2008, when the first Impella device received Food and Drug Administration clearance, its use has become increasingly prevalent. A variety of Impella devices are available, and are differentiated by size, power, and insertion techniques. These versions of the Impella have been used in a multitude of clinical scenarios, both emergent and elective, including high-risk coronary interventions, acute myocardial infarction complicated by cardiogenic shock, decompensated left and right heart failure, high-risk ventricular tachycardia ablations, and aortic valvuloplasty. However, the available evidence supporting its use is less than robust, primarily consisting of case reports and registries, with a limited number of randomized-controlled trials comparing the Impella with the intra-aortic balloon pump. Although these trials show that the Impella provides better hemodynamic support compared with the intra-aortic balloon pump, they failed to show a survival benefit for the Impella. This finding may have a number of explanations, foremost the inherent difficulty of selecting appropriate patients for trials that are conducted in extreme clinical settings. In this study, we discuss the mechanism of the Impella and the different types of Impella devices available, and review the medical literature for evidence of its efficacy in treating cardiac patients. Although the Impella has become ubiquitous in certain markets, such as in the USA, it has yet to be a part of the standard of care for patients in Israel. PMID- 29465439 TI - Intestinal re-transplantation: indications, techniques and outcomes. AB - PURPOSE OF REVIEW: The field of intestinal transplantation has shown significant growth and has become the gold standard therapy for patients that suffer from the complications of total parenteral nutrition due to irreversible intestinal failure. In the early years of intestinal transplant, retransplantation was associated with extremely high morbidity and mortality. The purpose of this review is to summarize recent encouraging reports, showing significant improvement in outcomes after intestinal retransplantation. RECENT FINDINGS: Recent studies at large volume centers have reported significant progress in patient and graft survival after intestinal retransplantation. Recent literature described the most common indications for retransplantation, surgical techniques, timing of graft enterectomy, immunologic monitoring, and complications. Improvement in outcomes due to advances in immunosuppression management and the importance of liver-containing grafts are also described. SUMMARY: Improving early to midterm patient and graft survival has made consideration for intestinal retransplantation even more necessary. Current clinical evidence supports the benefit of intestinal retransplantation in well selected recipients. Initial immunosuppression protocols, technical modifications, proper timing of enterectomy, and improved infectious disease monitoring have contributed to improved outcomes. PMID- 29465440 TI - Obesity management in the liver transplant recipient: the role of bariatric surgery. AB - PURPOSE OF REVIEW: The epidemic of obesity is having a marked impact on liver transplant candidates and recipients, and optimal approach for the obese liver transplant patient is not yet defined. The current review summarizes the role of bariatric surgery in obese liver transplant patients. RECENT FINDINGS: NASH is now the second most common indication for listing for liver transplantation and is the third most common reason for patients undergoing liver transplantation. Recent reports of outcomes for obese recipients demonstrate satisfactory patient and graft survival, though complication rates may be higher. The impact of weight loss on long-term health in the nontransplant population, including those with liver disease, has been demonstrated, though less in known on the impact for weight loss and bariatric surgery for liver transplant recipients. SUMMARY: Obesity-related liver disease has become one of the most common indications for liver transplantation and further research is needed to determine the role of bariatric surgery in the optimal management of this population.

PMID- 29465442 TI - Comparison Between Corticosteroid and Lidocaine Injection in the Treatment of Tennis Elbow: A Randomized, Double-Blinded, Controlled Trial. PMID- 29465443 TI - Outcome Trends of Adult Cancer Patients Receiving Inpatient Rehabilitation: A 13 Year Review. AB - OBJECTIVE: This study describes characteristics and trends of inpatient rehabilitation among cancer patients within the United States over a 13-yr period. DESIGN: This was a retrospective study of data from the Uniform Data System for Medical Rehabilitation from 2002 to 2014. Patients older than 17 yrs admitted to inpatient rehabilitation facilities with a diagnosis of malignant cancer were included. Trends of rehabilitation outcomes including length of stay, Functional Independence Measure (FIM) Instrument scores, and discharge location were examined. RESULTS: Data from 115,570 cancer patients were evaluated. Mean age was 66 +/- 14 yrs and 49% were women. Mean length of stay decreased over time (2002: 14 days to 2014: 13 days; P < 0.0005). Patient's admission total FIM scores decreased over time (2002: 68 +/- 18 to 2014: 61 +/- 16; P < 0.0005). The FIM change score increased over time (2002: 19 +/- 16 to 2014: 25 +/- 17; P < 0.0005). The greatest significant functional gains occurred in self care and transfers. Most patients (>70%) were discharged to the community. CONCLUSIONS: Cancer patients receiving acute inpatient rehabilitation demonstrated significant improvements in functional outcomes from admission to discharge. Cancer patients became more independent in important activities of daily living, thereby potentially reducing caregiver burden and ensuring safer discharges back to the community. This study suggests potential benefit of inpatient rehabilitation for appropriate cancer patients. PMID- 29465444 TI - Effects of Anodal Transcranial Direct Current Stimulation on Somatosensory Recovery After Stroke: A Randomized Controlled Trial. AB - OBJECTIVE: The aim of this study was to evaluate the effect of anodal transcranial direct current stimulation over the primary somatosensory cortex on the recovery of somatosensation, motor function, and the activities of daily living in patients with subacute stroke. DESIGN: This study was a prospective, randomized sham controlled, double-blinded study. Patients with subacute stroke having somatosensory deficits (N = 24) were enrolled and assigned randomly to the anodal and sham stimulation groups. Patients received 10 consecutive anodal or sham transcranial direct current stimulations over the primary somatosensory cortex on the side of the stroke lesion. Before and after each stimulation session, Nottingham sensory assessments, Semmes Weinstein monofilaments examination, and manual function tests were performed, and modified Brunnstrom classification, modified Barthel index, and functional ambulation categories were assessed. RESULTS: Although there was no clear significant difference between the two groups, when the changes from baseline to posttreatment evaluation were compared between the groups, a partially significant improvement was observed in the anodal stimulation group compared with the sham stimulation group. Interestingly, the tactile sensation of the unaffected side also improved. Moreover, the greater improvement in activities of daily living function was observed in the anodal stimulation group too. CONCLUSION: Anodal transcranial direct current stimulation over the primary somatosensory cortex may be a useful adjuvant therapy for the recovery of somatosensation and activities of daily living function in patients with sensory deficits after stroke. PMID- 29465445 TI - Regorafenib-Associated Fatigue: A Systematic Review and Meta-analysis. PMID- 29465447 TI - Extracellular vesicles in cardiovascular homeostasis and disease. AB - PURPOSE OF REVIEW: Extracellular vesicles have emerged as one of the most important means through which cells interact with each other and the extracellular environment, but extracellular vesicle research remains challenging due to their small size, limited amount of material required for traditional molecular biology assays and inconsistency in the methods of their isolation. The advent of new technologies and standards in the field, however, have led to increased mechanistic insight into extracellular vesicle function. Herein, the latest studies on the role of extracellular vesicles in cardiovascular physiology and disease are discussed. RECENT FINDINGS: Extracellular vesicles help control cardiovascular homeostasis and remodelling by mediating communication between cells and directing alterations in the extracellular matrix to respond to changes in the environment. The message carried from the parent cell to extracellular space can be intended for both local (within the same tissue) and distal (downstream of blood flow) targets. Pathological cargo loaded within extracellular vesicles could further result in various diseases. On the contrary, new studies indicate that injection of extracellular vesicles obtained from cultured cells into diseased tissues can promote restoration of normal tissue function. SUMMARY: Extracellular vesicles are an integral part of cell and tissue function, and harnessing the properties inherent to extracellular vesicles may provide a therapeutic strategy to promote tissue regeneration. PMID- 29465448 TI - Learning Through Boundary Crossing: Professional Identity Formation of Pharmacists Transitioning to General Practice in the Netherlands. AB - PURPOSE: To unravel boundary crossing as it relates to professional identity formation in pharmacists transitioning from a community pharmacy to working as nondispensing clinical pharmacists in general practice, with the aim of optimizing their education. METHOD: This was a multiple-case study, including two stage interviews, peer feedback, and individual reflection, that collected data in 2014-2016 from eight clinical pharmacists working in general practice in the Netherlands. These pharmacists acted-without a workplace role model-as pharmaceutical care providers in general practices during a 15-month training program. In within-case and cross-case analysis, data were collected regarding pharmacists' role development in practice and perceptions of learning processes, and examined through the lens of professional identity formation and boundary crossing. RESULTS: Analysis of data collected during and after the training program demonstrated that the clinical pharmacists who applied the learning mechanisms of reflection and transformation developed a patient-care-oriented professional identity. Some clinical pharmacists, who learned mainly through the mechanism of identification, did not integrate the new patient-care-oriented role into their professional identity. They felt that their workplace provided limited opportunities for reflection and transformation. Learning with peers on formal training days was seen as highly valuable for professional identity formation; it counterbalanced the lack of a role model in the workplace. CONCLUSIONS: Professional identity formation in the transition from community pharmacist to clinical pharmacist in general practice benefited from reflective, on-the-job training. This permitted transformative, boundary-crossing learning with peers and supported professional identity formation oriented to providing practice based pharmaceutical care. PMID- 29465446 TI - Current Practices and Attitudes Regarding Use of Inhaled Nitric Oxide in the NICU: Results From a Survey of Members of the National Association of Neonatal Nurse Practitioners. AB - BACKGROUND: Excessive supplemental oxygen exposure in the neonatal intensive care unit (NICU) can be associated with oxygen-related toxicities, which can lead to negative clinical consequences. Use of inhaled nitric oxide (iNO) can be a successful strategy for avoiding hyperoxia in the NICU. iNO selectively produces pulmonary vasodilation and has been shown to improve oxygenation parameters across the spectrum of disease severity, from mild to very severe, in neonates with hypoxic respiratory failure associated with persistent pulmonary hypertension of the newborn. PURPOSE: An online survey was conducted among members of the National Association of Neonatal Nurse Practitioners to gain insight into the level of understanding and knowledge among neonatal nurse practitioners (NNPs) about optimizing supplemental oxygen exposure and the use of iNO in the NICU setting. RESULTS: Of 937 NNP respondents, 51% reported that their healthcare team typically waits until the fraction of inspired oxygen level is 0.9 or more before adding iNO in patients not responding to oxygen ventilation alone. Among respondents with 1 or more iNO-treated patients per month, only 35% reported they know the oxygenation index level at which iNO should be initiated. Less than 20% of NNPs reported perceived benefits associated with early initiation of iNO for preventing progression to use of extracorporeal membrane oxygenation or reducing the length of hospital stay, and about one-third of respondents reported they believe early iNO use minimizes hyperoxia. IMPLICATIONS FOR PRACTICE: More education is needed for NNPs regarding the negative effects of oxidative stress in neonates. IMPLICATIONS FOR RESEARCH: Additional clinical trials investigating the most beneficial strategies for avoiding neonatal hyperoxia are warranted. PMID- 29465449 TI - A Comparison of Approaches for Mastery Learning Standard Setting. AB - PURPOSE: Defensible minimum passing standards (MPSs) must be used to evaluate learner performance outcomes in health professions education. In this study, the authors compared the results of traditional Angoff and Hofstee standard-setting exercises with the Mastery Angoff and Patient-Safety approaches for central venous catheter (CVC) insertion skills examinations. The authors also evaluated how these standards affected the historical performance of residents who participated in a simulation-based mastery learning (SBML) curriculum for CVC insertion skills. METHOD: In April and May 2015, 12 physicians with expertise in CVC insertion set MPSs for previously published internal jugular (IJ) and subclavian (SC) CVC insertion checklists using Angoff, Hofstee, Mastery Angoff, and Patient-Safety approaches. The resulting MPSs were compared using historical performance of internal medicine and emergency medicine residents who participated in CVC insertion SBML. RESULTS: The MPSs were set as follows: Angoff: IJ 91% checklist items correct, SC 90%. Hofstee: IJ 88%, SC 90%. Mastery Angoff: IJ 98%, SC 98%. Patient-Safety: IJ 98%, SC 98%. Based on the historical performance of 143 residents assessed on IJ and SC insertion, applying the 98% MPS would result in additional practice and retesting of 55/123 residents (45%) who had previously passed the IJ examination and 36/130 residents (28%) who had passed the SC examination using the Angoff and Hofstee MPSs. CONCLUSIONS: The Mastery Angoff and Patient-Safety standard-setting approaches resulted in higher CVC insertion SBML MPSs compared with traditional standard-setting methods. Further study should assess the impact of these more rigorous standards on patient outcomes. PMID- 29465450 TI - Gamification in Action: Theoretical and Practical Considerations for Medical Educators. AB - Gamification involves the application of game design elements to traditionally nongame contexts. It is increasingly being used as an adjunct to traditional teaching strategies in medical education to engage the millennial learner and enhance adult learning. The extant literature has focused on determining whether the implementation of gamification results in better learning outcomes, leading to a dearth of research examining its theoretical underpinnings within the medical education context. The authors define gamification, explore how gamification works within the medical education context using self-determination theory as an explanatory mechanism for enhanced engagement and motivation, and discuss common roadblocks and challenges to implementing gamification.Although previous gamification research has largely focused on determining whether implementation of gamification in medical education leads to better learning outcomes, the authors recommend that future research should explore how and under what conditions gamification is likely to be effective. Selective, purposeful gamification that aligns with learning goals has the potential to increase learner motivation and engagement and, ultimately, learning. In line with self determination theory, game design elements can be used to enhance learners' feelings of relatedness, autonomy, and competence to foster learners' intrinsic motivation. Poorly applied game design elements, however, may undermine these basic psychological needs by the overjustification effect or through negative effects of competition. Educators must, therefore, clearly understand the benefits and pitfalls of gamification in curricular design, take a thoughtful approach when integrating game design elements, and consider the types of learners and overarching learning objectives. PMID- 29465451 TI - How Mentor Identity Evolves: Findings From a 10-Year Follow-up Study of a National Professional Development Program. AB - PURPOSE: Despite academic medicine's endorsement of professional development and mentoring, little is known about what junior faculty learn about mentoring in implicit curricula of professional development programs, and how their mentor identity evolves in this context. The authors explored what faculty-participants in the Educational Scholars Program implicitly learned about mentoring and how the implicit curriculum affected mentor identity transformation. METHOD: Semistructured interviews with 19 of 36 former faculty-participants were conducted in 2016. Consistent with constructivist grounded theory, data collection and analysis overlapped. The authors created initial codes informed by Ibarra's model for identity transformation, iteratively revised codes based on incoming data patterns, and created visual representations of relationships amongst codes to gain a holistic, shared understanding of the data. RESULTS: In the implicit curriculum, faculty-participants learned the importance of having multiple mentors, the value of peer mentors, and the incremental process of becoming a mentor. The authors used Ibarra's model to understand how the implicit curriculum worked to transform mentor identity: Faculty-participants reported observing mentors, experimenting with different ways to mentor and to be a mentor, and evaluating themselves as mentors. CONCLUSIONS: The Educational Scholars Program's implicit curriculum facilitated faculty-participants taking on mentor identity via opportunities it afforded to watch mentors, experiment with mentoring, and evaluate self as mentor, key ingredients for identity construction. Leaders of professional development programs can develop faculty as mentors by capitalizing on what faculty-participants learn in the implicit curriculum and deliberately structuring postgraduation mentoring opportunities. PMID- 29465452 TI - Web-Enabled Mechanistic Case Diagramming: A Novel Tool for Assessing Students' Ability to Integrate Foundational and Clinical Sciences. AB - PROBLEM: As medical schools move from discipline-based courses to more integrated approaches, identifying assessment tools that parallel this change is an important goal. APPROACH: The authors describe the use of test item statistics to assess the reliability and validity of web-enabled mechanistic case diagrams (MCDs) as a potential tool to assess students' ability to integrate basic science and clinical information. Students review a narrative clinical case and construct an MCD using items provided by the case author. Students identify the relationships among underlying risk factors, etiology, pathogenesis and pathophysiology, and the patients' signs and symptoms. They receive one point for each correctly identified link. OUTCOMES: In 2014-2015 and 2015-2016, case diagrams were implemented in consecutive classes of 150 medical students. The alpha reliability coefficient for the overall score, constructed using each student's mean proportion correct across all cases, was 0.82. Discrimination indices for each of the case scores with the overall score ranged from 0.23 to 0.51. In a G study using those students with complete data (n = 251) on all 16 cases, 10% of the variance was true score variance, and systematic case variance was large. Using 16 cases generated a G coefficient (relative score reliability) equal to 0.72 and a Phi equal to 0.65. NEXT STEPS: The next phase of the project will involve deploying MCDs in higher-stakes settings to determine whether similar results can be achieved. Further analyses will determine whether these assessments correlate with other measures of higher-order thinking skills. PMID- 29465453 TI - Creation and Implementation of a Taxonomy for Educational Activities: A Common Vocabulary to Guide Curriculum Mapping. AB - PROBLEM: Undergraduate medical education (UME) has trended toward outcomes-based education, unveiling new issues for UME program organization and leadership. Using a common language for categorizing and linking all program components is essential. The Emory Curriculum Alignment Taxonomy (ECAT) was designed as a common vocabulary for curriculum mapping in the outcomes-based environment of the Emory University School of Medicine. APPROACH: The ECAT, developed in 2016, uses a set of 291 controlled identifiers, or "tags," to describe every educational activity's content, instruction, assessment, and outcomes, and thereby to align teaching inputs with student outcomes. Tags were drawn from external frameworks or developed by local stakeholders. A key feature is the arrangement of tags into eight categories, with the aim of balancing specificity and parsimony. Tags from multiple categories can be combined using Boolean operators to search for specific topics across the curriculum. OUTCOMES: In 2016-2017, all educational activities were tagged, including classroom events, workplace learning, mentored research, and student assessments. Tagging was done by two assistant deans and course/clerkship directors, which reinforced the importance of aligning instruction with assessment and aligning both of these with student outcomes. NEXT STEPS: Using the ECAT tags has linked instruction with achievement of student outcomes, has shown the compromises between specificity and parsimony were workable, and has facilitated comprehensive program management and evaluation. As the ECAT tags can be modified, other programs could adapt this approach to suit their context. Next steps will include aggregating data into a centralized repository to support reporting and research. PMID- 29465454 TI - The Impact of Surgeons on the Likelihood of Mastectomy in Breast Cancer. AB - OBJECTIVE: This study evaluates the impact of individual surgeons and institutions on the use of mastectomy or breast conserving surgery (BCS) among elderly women with breast cancer. SUMMARY OF BACKGROUND DATA: Current literature characterizes patient clinical and demographic factors that increase likelihood of mastectomy use. However, the impact of the individual provider or institution is not well understood, and could provide key insights to biases in the decision making process. METHODS: A retrospective cohort study of 29,358 women 65 years or older derived from the SEER-Medicare linked database with localized breast cancer diagnosed from 2000 to 2009. Multilevel, multivariable logistic models were employed, with odds ratios (ORs) used to describe the impact of demographic or clinical covariates, and the median OR (MOR) used to describe the relative impact of the surgeon and institution. RESULTS: Six thousand five hundred ninety-four women (22.4%) underwent mastectomy. Unadjusted rates of mastectomy ranged from 0% in the bottom quintile of surgeons to 58.0% in the top quintile. On multivariable analysis, the individual surgeon (MOR 1.97) had a greater impact on mastectomy than did the institution (MOR 1.71) or all other clinical and demographic variables except tumor size (OR 3.06) and nodal status (OR 2.95). Surgeons with more years in practice, or those with a lower case volume were more likely to perform mastectomy (P < 0.05). CONCLUSION: The individual surgeon influences the likelihood of mastectomy for the treatment of localized breast cancer. Further research should focus on physician-related biases that influence this decision to ensure patient autonomy. PMID- 29465455 TI - Commentary on Gomez et al.

PMID- 29465457 TI - Key Components of the Safe Surgical Ward: International Delphi Consensus Study to Identify Factors for Quality Assessment and Service Improvement. AB - OBJECTIVE: The aim of this study was to prioritize key factors contributing to safety on the surgical ward BACKGROUND:: There is a variation in the quality and safety of postoperative care between institutions. These variations may be attributed to a combination of process-related issues and structural factors. The aim of this study is to reach a consensus, by means of Delphi methodology, on the most influential of these components that may determine safety in this environment. METHODS: The Delphi questionnaire was delivered via an online questionnaire platform. The panel were blinded. An international panel of safety experts, both clinical and nonclinical, and safety advocates participated. Individuals were selected according to their expertise and extent of involvement in patient safety research, regulation, or patient advocacy. RESULTS: Experts in patient safety from the UK, Europe, North America, and Australia participated. The panel identified the response to a deteriorating patient and the care of outlier patients as error-prone processes. Prioritized structural factors included organizational and environmental considerations such as use of temporary staff, out-of-hours reduction in services, ward cleanliness, and features of layout. The latter includes dedicated areas for medication preparation and adequate space around the patient for care delivery. Potential quality markers for safe care that achieved the highest consensus include leadership, visibility between patients and nurses, and nursing team skill mix and staffing levels. CONCLUSION: International consensus was achieved for a number of factors across process-related and structural themes that may influence safety in the postoperative environment. These should be championed and prioritized for future improvements in patient safety at the ward-level. PMID- 29465458 TI - Prognostic Implications of Pathological Response to Neoadjuvant Chemoradiation in Pathologic Stage III Rectal Cancer. AB - OBJECTIVE: To evaluate the independent prognostic ability of the American Joint Committee on Cancer (AJCC) tumor regression scores within pathologic stage II and III rectal cancers. BACKGROUND: Response to neoadjuvant chemoradiation (nCRT) has been debated as a biologic surrogate for tumor biology and prognosis in rectal cancer. AJCC regression scores have been shown to correlate with prognosis. METHODS: Patient demographics, tumor characteristics, and AJCC scores (0 = complete response; 1 = isolated tumor cells remaining; 2 = residual cancer outgrown by fibrosis; 3 = extensive residual cancer) were assessed from 545 rectal cancer patients treated by nCRT followed by surgery at a single institution. Patients were classified as responders (score 0-2) or nonresponders (score 3). Survival analyses were performed using Cox proportional hazards models. RESULTS: Of 545 cases, 123 and 182 were pathologic stage II and III, respectively. Median follow-up was 4.9 years. AJCC regression scores were not independently prognostic within stage II cancers. However, AJCC scores were strongly associated with prognosis within stage III cancers (nonresponse 5-year overall survival [OS] 27% vs 67%, P < 0.001). Stage III responders (N = 139, 76.4%) had similar outcomes to stage II (5-year OS 67% vs 74%, P = 0.89). Conversely, stage III nonresponders (N = 43, 23.6%) approached stage IV outcomes (5-year OS 27% vs 18%, P = 0.09). On multivariable analysis, nonresponse (hazard ratio 3.2, 95% confidence interval 1.7-6.2), along with positive margin, abdominoperineal resection, and no adjuvant chemotherapy administration were independently associated with worse OS. CONCLUSIONS: AJCC response score after nCRT is a novel prognostic factor in pathologic stage III rectal cancer and may guide surveillance and adjuvant therapy decisions. PMID- 29465459 TI - Can We Do Better?: A Canadian Perspective on Firearm Injury Prevention. PMID- 29465460 TI - An Economic Evaluation of the National Surgical Quality Improvement Program (NSQIP) in Alberta, Canada. AB - OBJECTIVE: The aim of this study was to analyze the health care costs and savings associated with quality improvement (QI) interventions initiated and implemented utilizing NSQIP. BACKGROUND: Five acute care facilities of Alberta Health Services (AHS) adopted NSQIP in 2015 for a pilot project. METHODS: The cost savings of NSQIP were estimated from the start of NSQIP to the end of 2017 under an AHS perspective using this formula: Gross cost-savings = N * (p1 - p2) * unit cost, where N was the number of surgical patients after the intervention, p1 was the probability of event occurrence (within 30 days of surgery) before the intervention, p2 was the probability of event occurrence after the intervention, and unit cost is health care cost per event. To calculate the net cost-savings, we deducted the costs of NSQIP and its interventions from the gross cost-savings. RESULTS: The QI initiatives initiated by NSQIP to reduce surgical events had significant impacts clinically and economically. The gross cost-savings of NSQIP were estimated at $11.4 million. Subtracting the costs of NSQIP and its interventions ($2.6 million) from the gross cost-savings, the net cost-savings were $8.8 million. The return on investment ratio was 4.3, meaning that every $1.00 invested in NSQIP would bring $4.30 in returns. The sensitivity analysis showed the probability for NSQIP to be cost-saving was 95%. CONCLUSION: QI interventions initiated and implemented utilizing NSQIP appear to be effective and cost-saving for AHS. These cost-savings would be even larger if NSQIP was prolonged in the pilot sites and/or expanded to other sites across the province. PMID- 29465461 TI - Resident Autonomy in the Operating Room: How Faculty Assess Real-time Entrustability. AB - OBJECTIVE: This study aimed to identify the empirical processes and evidence that expert surgical teachers use to determine whether to take over certain steps or entrust the resident with autonomy to proceed during an operation. BACKGROUND: Assessing real-time entrustability is inherent in attending surgeons' determinations of residents' intraoperative autonomy in the operating room. To promote residents' autonomy, it is necessary to understand how attending surgeons evaluate residents' performance and support opportunities for independent practice based on the assessment of their entrustability. METHODS: We conducted qualitative semi-structured interviews with 43 expert surgical teachers from 21 institutions across 4 regions of the United States, using purposeful and snowball sampling. Participants represented a range of program types, program size, and clinical expertise. We applied the Framework Method of content analysis to iteratively analyze interview transcripts and identify emergent themes. RESULTS: We identified a 3-phase process used by most expert surgical teachers in determining whether to take over intraoperatively or entrust the resident to proceed, including 1) monitoring performance and "red flags," 2) assessing entrustability, and 3) granting autonomy. Factors associated with individual surgeons (eg, level of comfort, experience, leadership role) and the context (eg, patient safety, case, and time) influenced expert surgical teachers' determinations of entrustability and residents' final autonomy. CONCLUSION: Expert surgical teachers' 3-phase process of decisions on take-over provides a potential framework that may help surgeons identify appropriate opportunities to develop residents' progressive autonomy by engaging the resident in the determination of entrustability before deciding to take over. PMID- 29465462 TI - Fatal Diesel Poisoning: A Case Report and Brief Review of Literature. AB - Hydrocarbons are volatile substances that are used in routine life activities for cooking or as automobile fuel. Diesel is one of the commonly used automobile fuels obtained from crude oil. Death due to poisoning by diesel is rarely reported. Most commonly affected is the respiratory system either after aspiration or ingestion. The most common presentation is chemical pneumonitis or aspiration pneumonitis from which patient usually recovers. Gas chromatography techniques help in the detection of volatile substances like diesel. Here, we report a rare case of fatal pediatric accidental diesel poisoning. PMID- 29465463 TI - Novel therapeutics for bronchopulmonary dysplasia. AB - PURPOSE OF REVIEW: This review provides a concise summary of recent literature pertaining to emerging therapies for bronchopulmonary dysplasia (BPD). To provide context for the presented therapies, a brief overview of recently proposed changes to the definition of BPD and the concept of expanded respiratory outcomes is included. RECENT FINDINGS: New or redefined respiratory outcomes are required to improve accuracy in evaluating new therapies and correlating results with long term clinical outcomes of importance. Dexamethasone is no longer the only steroid based therapy showing promise for impacting BPD. Early trials indicate hydrocortisone, inhaled budesonide, and a budesonide-surfactant combination may be of benefit to preterm infants. Additionally, simple approaches like increasing utilization of mother's own milk may deserve more emphasis. Of significant interest is the traction stem cell therapies are acquiring as one of the more anticipated treatments for BPD. A new preclinical meta-analysis demonstrates the benefits of mesenchymal stromal cell therapy in animal models while the results of early clinical trials remain eagerly awaited. SUMMARY: BPD continues to be the most frequently occurring significant morbidity for extremely preterm infants, yet highly effective therapies remain elusive. Promising new treatments are on the horizon, but only continued efforts to complete well-designed clinical trials will determine the true impact of these emerging therapies. PMID- 29465464 TI - Immunostimulating and cancer-reductive experimental therapy with the oxazaphosphorine cytostatic SUM-IAP. AB - SUM-IAP is an aldo-ifosfamide-perhydrothiazine derivative that, under physiological conditions, spontaneously hydrolyzes to SUM-aldo-ifosfamide. In SUM IAP, one 2-chloroethyl group of the alkylating function of aldo-ifosfamide perhydrothiazine is substituted by a mesyl-ethyl group. The compound was synthesized to investigate the influence of the alkylating function of aldo ifosfamide on the antitumor activity of oxazaphosphorine cytostatics. In chemotherapy experiments in CD2F1 mice with advanced subcutaneously growing P388 mice leukemia cells, the primary tumor was reduced below the detection level with two highly dosed injections on days 7 and 8, but after 14 days, the primary tumor was measurable again. The primary tumor and detectable metastases killed the animals 29-30 days after SUM-IAP application. When, however, the animals were treated again with two highly dosed injections on day 14 and 15, a 4-5 times increase in the number of leukocytes was measured and all animals survived the observation period of 100 days. In the high, cancer-reductive dose range, SUM-IAP is not only a cytotoxic but also an immunostimulating oxazaphosphorine cytostatic. PMID- 29465465 TI - Pneumonia as a systemic illness. AB - PURPOSE OF REVIEW: The manuscript reviews the recent literature describing the occurrence, risk factors, recognition and treatment of sepsis, respiratory failure, and multiple organ dysfunction in patients with community-acquired pneumonia (CAP). RECENT FINDINGS: CAP may present with varying degrees of disease severity ranging from an almost asymptomatic infection to a fulminant systemic disease with both respiratory failure and multiple organ dysfunction. Severe sepsis occurs early in the course of the infection in more than 30% of cases. It may involve several organ systems and is associated with the severity and mortality of CAP. A number of factors exist, which may promote the transition of CAP from a local to a systemic disease, particularly immunosuppression and poorly controlled inflammatory responses, which promote extrapulmonary dissemination of the causative pathogens. Although CAP may be associated with complications involving most organ systems, much recent research has focused attention on cardiac complications, particularly those associated with pneumococcal infections. Biomarkers as a strategy for discriminating between invasive and noninvasive CAP have been comprehensively studied. A number of treatment strategies using antibiotics and various adjunctive therapies have been studied in severe CAP. SUMMARY: Recent research highlights the fact that CAP is frequently a systemic illness. PMID- 29465466 TI - The prevalence of unexplained falls and syncope in older adults presenting to an Irish urban emergency department. AB - AIM: There is growing evidence of an overlap between unexplained falls and syncope in older adults. Our aim was to examine the prevalence and associated resource utilization of these conditions in an urban emergency department (ED). PATIENTS AND METHODS: A single-centre, prospective, observational study was carried out over a 6-month period. Consecutive patients older than 50 years who presented to the ED because of a fall, collapse or syncope were included. Univariate analysis of demographic data is presented as percentages, mean (SD), 95% confidence intervals (CIs) and medians (interquartile range). Logistic regression modelling was used to examine the association between falls and resource utilization. RESULTS: A total of 561 patients fulfilled the inclusion criteria during the study period. Unexplained fallers accounted for 14.3% (n=80; 95% CI: 13.3-15.3) and syncope for 12.7% (n=71; 95% CI: 11.7-13.6) of all fall presentations. Overall, 50% (n=282; 95% CI: 48.20-52.34) of patients required admission to hospital. Patients with syncope [odds ratio (OR)=2.48, 95% CI: 1.45 4.23], and unexplained falls (OR=2.36, 95% CI: 1.37-4.08) were more likely to require admission than those with an explained falls. Unexplained fallers were nearly five times more likely to suffer recurrent falls (OR=4.97, 95% CI: 2.89 8.56). CONCLUSION: One in four older fallers presenting to ED have symptoms suggestive of syncope or an unexplained fall. There are significant biological consequences of recurrent falls including greater rates of cognitive decline, gait and mobility disturbances, depression and frailty. Recognition that syncope can present as an unexplained fall in older adults is important to ensure that appropriate early modifiable interventions are initiated.

PMID- 29465467 TI - Outcome and predictors of remission in bipolar-I patients experiencing manic episode and treated with oral antipsychotics and/or mood stabilizers: a prospective observational study in Italy. AB - This observational study aimed to identify internal (clinical-demographic, temperamental characteristics) and external (childhood trauma, psychosocial characteristics) factors potentially predicting remission at 12 weeks in bipolar I patients experiencing manic episode and requiring to start or switch treatment with oral antipsychotics and/or mood stabilizers. The following scales were administered: the Young Mania Rating Scale (YMRS), the Montgomery-Asberg Depression Rating Scale (MADRS), the Functioning Assessment Short Test (FAST), and the Clinical Global Impression for Bipolar Disorders (CGI-BP). A logistic regression analysis was carried out to test the effect of the explored factors on remission rate (YMRS score <=12), functionality, and clinical outcomes at week 12. Overall, 243 patients were enrolled and 197 (81.1%) completed the follow-up. Remission at week 12 was achieved in 200 (82.3%) patients. Marked improvements from baseline were observed in MADRS, FAST, CGI-BP mania, and bipolar illness scores. None of the factors was associated with remission, or showed strong correlations with the improvements in clinical health state. In our sample, after 12 weeks of initiation or change of oral therapy for mania in bipolar-I patients, treatment was associated with rapid improvements in symptoms and functioning in most patients. Factors predictive of remission and clinical improvements in manic symptoms were not identified. PMID- 29465469 TI - A critical appraisal of gabapentinoids for pain in cancer patients. AB - PURPOSE OF REVIEW: Gabapentinoids are frequently used in the management of cancer pain. In recent Cochrane systematic reviews, although there was an abundance of evidence relating to non-cancer pain, only a few studies related to cancer pain. This review summarizes recent randomised controlled trials (RCTs) evaluating the use of gabapentinoids for tumour-related (as monotherapy or part of combination therapy) and treatment-related pain. RECENT FINDINGS: For tumour-related pain, ten out of thirteen studies showed statistically significant benefits in favour of gabapentinoids. When used, as part of monotherapy or combination therapy, benefits were observed in five out of six studies evaluating gabapentin, and in six out of eight studies evaluating pregabalin. For treatment-related pain, none of the four studies (two gabapentin, two pregabalin) showed statistically significant benefits in favour of gabapentinoids. Unfortunately, many of the studies included were limited by small sample size, lack of blinding, and inadequate follow-up. SUMMARY: More and better quality studies are required, although it may be challenging to accomplish in this patient population. Gabapentinoids may offer benefits to cancer patients with pain, but careful titration and monitoring of adverse effects is necessary. PMID- 29465470 TI - Opioid addiction, diversion, and abuse in chronic and cancer pain. AB - PURPOSE OF REVIEW: The primary cause of overdose death in the United States is related to pharmaceutical opioids. A few particular populations that struggle with adverse outcomes related to opioid abuse are those in palliative care, those with chronic pain, and those receiving pain treatments secondary to cancer or chemotherapy. RECENT FINDINGS: There have been massive efforts to decrease the use of opioid abuse in patient care in a gestalt manner, but palliative care provides unique challenges in applying these reduction tactics used by other specialties. SUMMARY: We explore behavioral interventions, provider education, alternative pain management techniques, postmarketing surveillance, and abuse deterrent formulas as emerging methods to counteract opioid abuse in these populations. PMID- 29465471 TI - Perioperative venous thromboembolism in urologic oncology procedures, risk factors, and prevention. AB - PURPOSE OF REVIEW: Venous thromboembolism (VTE) is a common complication during the perioperative period for major urologic oncology operations. The present review focuses on the risk factors, the mechanisms of hypercoagulability in this patient population, and the timing and prevention of VTE. RECENT FINDINGS: Although the vast majority of patients undergoing major urologic oncology operations do not develop VTEs, when they do develop they can be fatal. The risk factors for VTEs are important to identify in this patient population. The timing of VTE events are also essential to understanding their prevention. Prevention focused around the perioperative period is the best way to reduce fatal complications secondary to a VTE event. SUMMARY: VTEs are common and can potentially be fatal. Prevention in high-risk patients during the most vulnerable perioperative time period should be the focus of clinical efforts to reduce VTE complications and the associated morbidity and mortality. PMID- 29465472 TI - A new prognostic score can predict survival after hepatocellular carcinoma treatment in a cohort of 1302 Egyptian hepatocellular carcinoma patients. AB - INTRODUCTION: Survival of hepatocellular carcinoma (HCC) differs between regions and countries according to the different underlying factors and the degree of standard of care that enables early diagnosis and management. Our aim was to identify the most potent predictive factors of survival in Egyptian HCC patients receiving curative or palliative treatments. PATIENTS AND METHODS: This retrospective study included 1302 HCC patients attending the HCC multidisciplinary clinic, Cairo University, between February 2009 and December 2016. Clinical, laboratory, tumor characteristics, and treatment data were collected. Prognostic scores for each of the treatment categories, curative or palliative, were developed using routine laboratory tests. RESULTS: Patients were predominantly men, mean age 57.79+/-7.56 years. All cases developed HCC in addition to cirrhosis, mainly hepatitis C virus-related (88.2%). Most of the patients were Child-Pugh A (56.8%) or B (34.4%) and had single lesions. Transarterial chemoembolization was the most common line of treatment (42.08%). The overall median survival was 18.3 months from the date of diagnosis. Cigarette smoking, Child-Pugh score, performance status, number and size of the focal lesion, alpha-fetoprotein, and application of a specific treatment, particularly curative treatment, were the significant independent prognostic factors for survival. We found no impact of diabetes mellitus or hypertension on survival. Multidisciplinary HCC clinic predictive scores of survival after palliative and curative treatments were developed including independent prognostic factors, age, and portal vein status. CONCLUSION: A new Egyptian prognostic score of tumor and patients factors can predict the survival of patients with HCC after palliative and curative treatments. PMID- 29465473 TI - Characteristics of patients with hepatitis C virus-related chronic liver diseases just before the era of oral direct-acting antiviral therapy in Italy. AB - BACKGROUND: In 2017, oral direct-acting antiviral (DAA) therapy for chronic hepatitis C virus (HCV) infection became available free of charge for all HCV-RNA positive patients, irrespective of their fibrosis stage. AIM: The aim of this study was to evaluate the characteristics of HCV-related chronic liver disease (CLD) in Italy just before the introduction of DAA therapy. PATIENTS AND METHODS: Patients with CLD were enrolled in two national surveys conducted in 2001 and in 2014. The two surveys prospectively enrolled patients aged older than 18 years referring to Italian liver units throughout the country using a similar clinical approach and analytical methods. RESULTS: Out of the 12 564 patients enrolled, 8447 (67.3%) were anti-HCV-positive, with a decreasing trend from 69.0% in 2001 to 60.4% in 2014. During this period, an increasing trend over time was observed in the mean age of patients (55.6 vs. 59.1 years; P<0.01), in the proportion of patients with liver cirrhosis (19.4 vs. 28.2%; P<0.01), and in the circulation of genotype 4 (0 vs. 6.1%). The multiple logistic analysis showed that age older than 60 years, birth in southern Italy, and multiple etiology (HCV+hepatitis B virus or HCV+alcohol) are independent predictors of a likelihood of liver cirrhosis, whereas a higher level of education plays a protective role (odds ratio: 0.65; 95% confidence interval=0.57-0.76). CONCLUSION: Currently, in Italy, chronic HCV infection plays a decreasing role in CLD, showing a shift toward older age groups and a more severe disease stage. These data, relating to just before the era of DAA therapy for this infection, represent up-to-date reference data for evaluating the effectiveness of DAAs in the future. PMID- 29465474 TI - Smartphone technology: a reliable and valid measure of knee movement in knee replacement. AB - Knee range of motion (ROM) following a knee arthroplasty is an important clinical outcome that directly relates to the patient's physical function. Smartphone technology has led to the creation of applications that can measure ROM. The aim was to determine the concurrent reliability and validity of the photo-based application 'Dr Goniometer' (DrG) compared with a universal goniometer performed by a clinician. A smartphone camera was used to take photographs of the knee in full flexion and full extension, and the images were sent by participants to a study phone. Participants then rated the ease of participation. To assess validity, the patient's knee was measured by a clinician using a goniometer. To examine reliability, four clinicians assessed each image using DrG on four separate occasions spaced 1 week apart. A total of 60 images of knee ROM for 30 unicondylar or total knee arthroplasty were assessed. The goniometer and DrG showed strong correlations for flexion (r=0.94) and extension (r=0.90). DrG showed good intrarater reliability and excellent inter-rater reliability for flexion (intraclass correlation coefficient=0.990 and 0.990) and good reliability for extension (intraclass correlation coefficient=0.897 and 0.899). All participants found the process easy. DrG was proven to be a valid and reliable tool in measuring knee ROM following arthroplasty. Smartphone technology, in conjunction with patient-reported outcomes, offers an accurate and practical way to remotely monitor patients. Benefit may be found in differentiating those who need face-to-face clinical consult to those who do not. PMID- 29465476 TI - Idiopathic pulmonary fibrosis: A guide for nurse practitioners. AB - Idiopathic pulmonary fibrosis (IPF) is a rare disease characterized by decline in lung function, dyspnea, and cough. The clinical course of IPF is variable and unpredictable. Early referral to specialists is key to ensure timely and accurate diagnosis. Two antifibrotic drugs (nintedanib and pirfenidone) have been approved for the treatment of IPF. PMID- 29465475 TI - Physical Activity and Bone Accretion: Isotemporal Modeling and Genetic Interactions. AB - PURPOSE: This study aimed to determine if replacing time spent in high- and low impact physical activity (PA) predicts changes in pediatric bone mineral density (BMD) and content (BMC). METHODS: We analyzed data from the longitudinal Bone Mineral Density in Childhood Study (N = 2337 with up to seven visits). The participants were age 5-19 yr at baseline, 51.2% were female, and 80.6% were nonblack. Spine, total hip, and femoral neck areal BMD and total body less head (TBLH) BMC Z-scores were calculated. Hours per day spent in high- and low-impact PA were self-reported. Standard covariate-adjusted (partition model) and time allocation-sensitive isotemporal substitution modeling frameworks were applied to linear mixed models. Statistical interactions with sex, self-reported ancestry, age, and bone fragility genetic scores (percentage of areal BMD-lowering alleles carried) were tested. RESULTS: In standard models, high-impact PA was positively associated with bone Z-score at all four skeletal sites (e.g., TBLH-BMC Z-score: beta = 0.05, P = 2.0 * 10), whereas low-impact PA was not associated with any of the bone Z-scores. In isotemporal substitution models, replacing 1 h.d of low- for high-impact PA was associated with higher bone Z-scores (e.g., TBLH-BMC Z score: beta = 0.06, P = 2.9 * 10). Conversely, replacing 1 h.d of high- for low impact PA was associated with lower bone Z-scores (e.g., TBLH-BMC Z-score: beta = -0.06, P = 2.9 * 10). The substitution associations were similar for each sex and ancestry group, and for those with higher and lower genetic scores for bone fragility (P-interactions > 0.05), but increased in strength among the older adolescents (P-age interactions < 0.05). CONCLUSIONS: Time-sensitive models suggest that replacing low-impact PA for high-impact PA would be beneficial for the growing skeleton in the majority of children.

AB - BACKGROUND: Comparing postvaccination fever rates in pediatric influenza vaccine clinical trials is difficult due to variability in how fever is reported. The impact of vaccine-related fever and antipyretic use on trivalent influenza vaccine immunogenicity in children is also unclear. METHODS: In this pilot study, we used individual-level data provided by GlaxoSmithKline from 3 pediatric clinical trials of GlaxoSmithKline versus comparator trivalent influenza vaccine. We explored a primary study (NCT00764790), the largest trial involving young children (6-35 months, n = 3317), and further explored key findings in the 2 other trials (3-17 years, NCT00980005; 6 months to 17 years, NCT00383123). We analyzed postvaccination fever and antipyretic use, and their association with immunogenicity through use of multivariable regression. RESULTS: Postvaccination fever data were reanalyzed from the primary study using the Brighton Collaboration standardized definition (vaccine-related fever >=38 degrees C, measured by any route, reported after each dose). Rates were substantially lower after first (2.7%-3.4%) and second doses (3.3%-4.1%), than those published (6.2% 6.6%; combined dose data, any causality). A pooled immunogenicity analysis combining the 3 studies (n = 5902) revealed children with postvaccination fever had significantly higher adjusted geometric mean titers than those without fever (ratio, 1.21-1.39; P <= 0.01). Conversely those with antipyretic use had significantly lower adjusted geometric mean titers (ratio, 0.80-0.87; P < 0.0006), dependent on virus strain. CONCLUSIONS: Varying analyses and reporting methods can result in substantially different reported fever rates in studies. Standardized reporting of fever is needed to facilitate comparison between studies. Fever and antipyretic use may have important associations with influenza vaccine immunogenicity in children and need further prospective investigation. PMID- 29465478 TI - Glutamatergic Modulators in Depression. AB - LEARNING OBJECTIVE: After participating in this activity, learners should be better able to evaluate the evidence supporting the antidepressant effects of glutamatergic modulators.Both preclinical and clinical studies have implicated glutamatergic system dysfunction in the pathophysiology of mood disorders such as bipolar depression and major depressive disorder. In particular, rapid reductions in depressive symptoms have been noted in response to subanesthetic doses of the glutamatergic modulator ketamine in subjects with major depressive disorder or bipolar depression. These results have prompted the repurposing or development of other glutamatergic modulators, both as monotherapy or adjunctive to other therapies. Here, we highlight the evidence supporting the antidepressant effects of various glutamatergic modulators, including (1) broad glutamatergic modulators (ketamine, esketamine, dextromethorphan, dextromethorphan-quinidine [Nuedexta], AVP-786, nitrous oxide [N2O], AZD6765), (2) subunit (NR2B)-specific N-methyl-D aspartate (NMDA) receptor antagonists (CP-101,606/traxoprodil, MK-0657 [CERC 301]), (3) glycine-site partial agonists (D-cycloserine, GLYX-13, sarcosine, AV 101), and (4) metabotropic glutamate receptor modulators (AZD2066, RO4917523/basimglurant, JNJ40411813/ADX71149, R04995819 [RG1578]). PMID- 29465481 TI - Murine Typhus in South Texas Children: An 18-year Review. AB - BACKGROUND: Murine typhus is a zoonotic infection caused by Rickettsia typhi that remains endemic in South Texas. In 2003, only 9 Texas counties reported murine typhus compared with 41 counties in 2013. METHODS: A retrospective study of children discharged with a confirmed diagnosis of murine typhus from Driscoll Children's Hospital between January 1998 and September 2016. RESULTS: Two hundred thirteen children (113 female) 3 months through 19 years of age (mean, 11.2 +/- 4.5 years) were identified. Cases occurred throughout the year. Children were admitted after a mean of 7.7 +/- 5.3 days of fever. The most common symptoms were fever (100%), poor appetite (71.9%), malaise/fatigue (69.0%) and headache (67.6%). The most common laboratory abnormalities were elevated C-reactive protein, hypoalbuminemia, elevated erythrocyte sedimentation rate, elevated transaminases and elevated band count with normal total white blood cell count. Children defervesced in a mean of 31.87 +/- 21.36 hours after initiation of doxycycline. Hospitalization lasted for a mean of 2.7 +/- 1.8 days when children were administered doxycycline within 24 hours of admission compared with, 4.1 +/- 1.8 days, P <= 0.0001 when started later. Eleven patients (5.1%) were admitted to the pediatric intensive care unit and were older, P = 0.0009. No children died. CONCLUSIONS: Murine typhus is endemic in South Texas. Children who were treated earlier with doxycycline had a shorter hospitalization than were those who began therapy later. Recognition of murine typhus is important to prevent delay in treatment and development of complications. PMID- 29465479 TI - Ketamine-Associated Brain Changes: A Review of the Neuroimaging Literature. AB - Major depressive disorder (MDD) is one of the most prevalent conditions in psychiatry. Patients who do not respond to traditional monoaminergic antidepressant treatments have an especially difficult-to-treat type of MDD termed treatment-resistant depression. Subanesthetic doses of ketamine-a glutamatergic modulator-have shown great promise for rapidly treating patients with the most severe forms of depression. As such, ketamine represents a promising probe for understanding the pathophysiology of depression and treatment response. Through neuroimaging, ketamine's mechanism may be elucidated in humans. Here, we review 47 articles of ketamine's effects as revealed by neuroimaging studies. Some important brain areas emerge, especially the subgenual anterior cingulate cortex. Furthermore, ketamine may decrease the ability to self-monitor, may increase emotional blunting, and may increase activity in reward processing. Further studies are needed, however, to elucidate ketamine's mechanism of antidepressant action. PMID- 29465482 TI - Soft Tissue Metrics in Thyroid Eye Disease: An International Thyroid Eye Disease Society Reliability Study. AB - PURPOSE: To determine the reliability of 3 scales for assessing soft tissue inflammatory and congestive signs associated with thyroid eye disease. METHODS: This was a multicentered prospective observational study, recruiting 55 adults with thyroid eye disease from 9 international centers. Six thyroid eye disease soft tissue features were measured; each sign graded using 3 scales (presence/absence [0-1], 3-point scale [0-2], and percentage [0-100]). Each eye was graded twice by 2 independent raters. Accuracy (fraction of agreement) was calculated between the 2 trials for each rater (intrarater reliability) and between raters for all trials (interrater reliability) to determine the most sensitive scale for each feature that maintained a threshold of agreement greater than 0.70. Trial, intrarater reliability, and interrater reliability were determined by accuracy measurement of agreement for each inflammatory/congestive feature. RESULTS: Fifty-five patients had 218 assessments for 6 thyroid eye disease metrics. The intrarater reliability for each feature was consistently better than the interrater reliabilities. Using an agreement of 0.70 or better, for the interrater tests, conjunctival and eyelid edema could be reliably measured using the 0-1 or 0-2 scale while conjunctival and eyelid redness could only be reliably measured with the binary 0-1 scale. Caruncular edema and superior conjunctival redness could not be measured reliably between 2 raters with any scale. The percentage scale had poor agreement unless slippage intervals of >20% were allowed on either side of the measurements. CONCLUSIONS: Of the specific periocular soft tissue inflammatory features measured between raters in the Clinical Activity Score and Vision, Inflammation, Strabismus, Appearance scales, edema of the eyelids and conjunctiva could reliably be measured by both 0 1 and 0-2 scales, erythema of the eyelid and bulbar conjunctiva could reliably be measured only by the 0-1 scale, and the other parameters of superior bulbar erythema and caruncular edema were not reliably measured by any scale. PMID- 29465483 TI - Case Series: Noninflammatory Thyroid Eye Disease. AB - PURPOSE: Patients presenting with thyroid eye disease (TED) usually follow a well defined self-remitting course characterized by an active inflammatory phase followed by an inactive fibrotic phase. We present 3 cases where patients presented primarily with signs of progressive fibrosis and no signs of prior active inflammation. METHODS: We reviewed the clinical notes and investigations of 3 patients who presented to our center between January 2015 and August 2017. RESULTS: All patients included in the study presented primarily with severe, progressive fibrosis without evidence of a previous active inflammatory condition. Although there were no signs of inflammation, each case was progressive, with 2 of the cases developing dysthyroid optic neuropathy that was relatively recalcitrant. We found that these patients were older than the general population of TED patients and that their disease course represents a departure from the common narrative. CONCLUSIONS: This subgroup of TED patients do not conform to the typical inflammatory natural history of TED. We propose that the heterogeneity of the orbital fibroblast pool and their function may be different in this subgroup. Further work will be required to reveal the pathophysiology of this atypical TED process, potentially revealing links between aging and the inflammatory mediators in TED. PMID- 29465484 TI - Expansion Vibration Lipofilling: A New Technique in Large-Volume Fat Transplantation. AB - BACKGROUND: Despite rapid growth, gluteal fat transplantation is an operation in search of science and a teachable technique. Long operating times, tedious syringe transfers, inability to shape the recipient site, and the risk of fat embolism all headline as impediments to clinical adoption of the procedure. Expansion vibration lipofilling is a syringe-free surgical strategy that is a logical extension of Separation, Aspiration, and Fat Equalization (SAFELipo). In expansion vibration lipofilling, there is simultaneous disruption of recipient site connective tissue, internal expansion using exploded-tip cannulas, and backfilling of these spaces with roller pump-propelled fat. METHODS: Two thousand four hundred nineteen consecutive cases of expansion vibration lipofilling fat transplantation to the buttocks were reviewed. Average follow-up was 12 months. The technique of expansion vibration lipofilling is dependent on the use of larger caliber cannulas attached to a roller pump and to an oscillatory power assisted liposuction device, which is less labor-intensive, potentially allowing for better knowledge of cannula-tip location at all times during the procedure. RESULTS: Operating times averaged 1 hour 40 minutes. The average volume of fat inserted was 1003 cc. Complications included donor-site seroma, infection, and one pulmonary embolism treated with anticoagulation. There were no cases of fat embolism or death. CONCLUSIONS: Expansion vibration lipofilling is a new method for large-volume fat transplantation. Avoidance of fatal fat emboli demands a surgeon's complete knowledge of cannula tip location at all times during the procedure. Syringe-free, larger caliber, and less flexible cannulas, combined with techniques requiring less operator upper extremity effort resulting in less fatigue, may contribute to avoidance of this dreadful complication. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV. PMID- 29465486 TI - Hypercholesterolemia Is Associated with the Subjective Evaluation of Postoperative Outcomes in Patients with Idiopathic Carpal Tunnel Syndrome Who Undergo Surgery: A Multivariate Analysis. AB - BACKGROUND: Carpal tunnel syndrome is a compression neuropathy of the median nerve at the wrist; its symptoms include neuropathic pain and sensory and motor disturbance distributed by the median nerve. Carpal tunnel syndrome and hypercholesterolemia have similar backgrounds, but the effect of these similarities on postoperative outcomes has not been reported. Using multivariate analysis, the authors analyzed the relationship between prognostic factors, including the presence of hypercholesterolemia, and subjective postoperative outcomes of patients with idiopathic carpal tunnel syndrome. METHODS: Of 168 hands with carpal tunnel syndrome that were treated surgically, 141 that were followed up and assessed 1 year postoperatively or thereafter were included. The mean postoperative follow-up period was 40.8 months. Surgery was performed through a small palmar skin incision under local anesthesia. The outcomes were postoperative symptoms, including pain and numbness, and overall Kelly assessment. RESULTS: Preoperative numbness and pain resolved and alleviated in 94 of 141 hands and was diminished in 59 of 64 hands. Univariate analysis showed that postoperative numbness and Kelly assessment were significantly associated with hypercholesterolemia. Multivariate analysis showed that postoperative numbness was significantly associated with smoking and hypercholesterolemia, and Kelly assessment was significantly associated with smoking (adjusted OR, 3.3; 95 percent CI, 1.1 to 10; p = 0.04) and hypercholesterolemia (adjusted OR, 2.9; 95 percent CI, 1.4 to 6.3; p = 0.01). CONCLUSION: Hypercholesterolemia, usually a systemic condition in sites other than the hand, is associated with the subjective evaluation of postoperative symptoms in patients with idiopathic carpal tunnel syndrome. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III. PMID- 29465485 TI - Enhanced Recovery Pathway in Microvascular Autologous Tissue-Based Breast Reconstruction: Should It Become the Standard of Care? AB - BACKGROUND: Enhanced recovery pathway programs have demonstrated improved perioperative care and shorter length of hospital stay in several surgical disciplines. The purpose of this study was to compare outcomes of patients undergoing autologous tissue-based breast reconstruction before and after the implementation of an enhanced recovery pathway program. METHODS: The authors retrospectively reviewed consecutive patients who underwent autologous tissue based breast reconstruction performed by two surgeons before and after the implementation of the enhanced recovery pathway at a university center over a 3 year period. Patient demographics, perioperative data, and 45-day postoperative outcomes were compared between the traditional standard of care (pre-enhanced recovery pathway) and enhanced recovery pathway patients. Multivariate logistic regression was performed to identify risk factors for length of hospital stay. Cost analysis was performed. RESULTS: Between April of 2014 and January of 2017, 100 consecutive women were identified, with 50 women in each group. Both groups had similar demographics, comorbidities, and reconstruction types. Postoperatively, the enhanced recovery pathway cohort used significantly less opiate and more acetaminophen compared with the traditional standard of care cohort. Median length of stay was shorter in the enhanced recovery pathway cohort, which resulted in an extrapolated $279,258 savings from freeing up inpatient beds and increase in overall contribution margins of $189,342. Participation in an enhanced recovery pathway program and lower total morphine equivalent use were independent predictors for decreased length of hospital stay. Overall 45-day major complication rates, partial flap loss rates, emergency room visits, hospital readmissions, and unplanned reoperations were similar between the two groups. CONCLUSION: Enhanced recovery pathway program implementation should be considered as the standard approach for perioperative care in autologous tissue-based breast reconstruction because it does not affect morbidity and is associated with accelerated recovery with reduced postoperative opiate use and decreased length of hospital stay, leading to downstream health care cost savings. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III. PMID- 29465487 TI - Incidental Detection of Type B2 Thymoma on 68Ga-Labeled Prostate-Specific Membrane Antigen PET/CT Imaging. AB - Ga-labeled prostate-specific membrane antigen is a novel radiotracer for imaging of prostate cancer. We report a hormonally treated patient with prostate carcinoma, presenting with lower urinary tract symptoms and rising prostate specific antigen levels, who underwent Ga-labeled prostate-specific membrane antigen PET/CT for suspected recurrence. No tracer avid lesion was noted in the prostate gland and locoregional area. However, intense tracer avid heterogeneously enhancing soft tissue lesion with cystic areas and coarse calcifications was seen in the anterior mediastinum. PET/CT-guided biopsy from the mediastenal lesion revealed type B2 thymoma. PMID- 29465488 TI - FDG PET and MRI Findings in a Case of Bing-Neel Syndrome. AB - A 64-year-old man was admitted for expressive aphasia with lack of words. He had been diagnosed with Waldenstrom 4 years before. At that time, he received 6 cycles of single-agent fludarabine, and remission was obtained. Because of acute expressive aphasia, he underwent brain MRI, which showed frontoparietal and insular subcortical gadolinium enhancement; Bing-Neel syndrome was suspected. Fronto-temporo-insular hypometabolism and left parietal hypometabolism were highlighted on FDG PET/CT. Structural and functional brain imaging revealed impairment of brain areas due to white matter changes and reinforced the diagnosis.

AB - A 58-year-old man with Gleason 4+3 prostate cancer was initially treated by radical prostatectomy followed by salvage radiotherapy to the prostate bed for postoperative biochemical failure. One year later, F-fluorocholine PET/CT detected a pelvic lymph node recurrence, which was treated with radiation therapy and 6 months of androgen deprivation. PSA started to rise again 18 months later, but F-fluciclovine PET/CT failed to demonstrate the site of recurrence at a PSA of 0.63 ng/mL. However, Ga-PSMA PET/CT revealed a single positive 4-mm perirectal lymph node (PSA 0.80 ng/mL at time of scan), in retrospect anatomically apparent but negative on F-fluciclovine PET/CT. PMID- 29465490 TI - 99mTc-MDP SPECT-CT and Ultrasound in the Diagnosis and Staging of Thyroid Metastasis From Osteosarcoma. AB - The classification of thyroid nodules in children is often difficult, especially in pretreated patients with metastatic disease. In osteosarcoma patients, Tc-MDP SPECT/CT is used for primary and follow-up staging. Bone and soft tissue metastases can be revealed because of Tc-MDP imaging of osteoid-producing metastases. We present Tc-MDP SPECT-CT, CT, and ultrasound images of a highly suspicious calcified thyroid lesion in a 17-year-old boy with osteosarcoma. High uptake in Tc-MDP SPECT-CT provides diagnosis of thyroid metastasis of osteosarcoma, which was proven by histopathology.

AB - FDG PET/CT was performed in a 30-year-old woman to detect the source of fever of unknown origin. The images showed widespread abnormal activity, consistent with lymphoma. However, lymph node biopsy revealed only inflammation, and a diagnosis of familial hemophagocytic lymphohistiocytosis was eventually made after familial hemophagocytic lymphohistiocytosis-specific gene was detected. After proper therapy, a follow-up FDG PET/CT examination 2 months later showed resolution of most of the previously seen lesions. PMID- 29465492 TI - Seizure-Induced Increased 18F-DOPA Uptake in a Child With Diffuse Astrocytoma and Transient Brain MRI Abnormalities Related to Status Epilepticus. AB - We report the finding of increased F-DOPA uptake in the brain parenchyma surrounding a temporoparietal low-grade diffuse astrocytoma and corresponding to transient seizure-induced MRI abnormalities. There was concomitant markedly increased tumoral uptake. This F-DOPA PET phenomenon may represent increased amino acid transport induced by seizures. In the setting of brain tumor imaging, increased F-DOPA uptake of low-grade epileptogenic tumors and adjacent brain parenchyma should be carefully interpreted in light of clinical and electroencephalographic findings related to seizure activity.

AB - An 85-year-old man with prostate cancer for metastatic workup underwent Gallium Prostate-Specific Membrane Antigen (Ga-PSMA) PET/CT (Ga-PSMA PET/CT), which revealed unusual tracer uptake in the shaft and glans of penis as well as multiple systemic metastases in liver, skeletal, and lymph nodes. The penile lesion was proved to be metastatic adenocarcinoma from prostate on fine needle aspiration cytology. The patient underwent Lutetium (Lu)-labeled PSMA radioligand therapy, which also revealed diffuse tracer uptake in the penile shaft as well as other metastatic sites. PMID- 29465494 TI - 68Ga-PSMA PET/CT Revealing Unusual Inguinal Canal and Distant Nodal Metastasis in a Case of Castration-Resistant Prostate Cancer. AB - Gallium-prostate-specific membrane antigen (Ga-PSMA) is well established in the imaging of prostate cancer (PC). Here, we report a case of castration-resistant PC who underwent Ga-PSMA PET/CT for recurrence evaluation, which revealed metastatic lesions in distant lymph nodes and additionally an unusual metastatic deposit in the inguinal canal. The second Ga-PSMA PET/CT done after oral hormonal therapy yielded a favorable response. This pattern of distant metastatic spread is a rare presentation of PC, and PSMA PET/CT revealed the unusual metastasis in the inguinal canal with a timely therapy culminating in favorable disease response. PMID- 29465496 TI - A Systematic Review of Exercise Training in Patients With Cardiac Implantable Devices. AB - PURPOSE: This systematic review identified exercise-based intervention studies in patients with cardiac implantable devices (CIDs): implantable cardioverter defibrillator (ICD), cardiac resynchronization pacemaker or defibrillator (cardiac resynchronization therapy [CRT]), or ventricular assist device (VAD) and assessed evidence for the safety and efficacy of exercise-based interventions alone or in combination with psychoeducational components. METHODS: PubMed, EMBASE, CINAHL Plus, Web of Science, Cochrane, and PEDro databases were searched from database inception to September 2016. Data were extracted and validity was assessed by 2 reviewers. Study quality was evaluated using the JADAD scale for randomized controlled trials. A total of 3991 articles for all CIDs (ICD: 1015; pacemaker: 1630; and VAD: 1346) were screened for relevance. Subsequently, 24 full-text articles (ICD: 14; CRT: 4; and VAD: 6) were deemed eligible for this review. RESULTS: Studies of aerobic exercise training demonstrated an average increase in peak oxygen uptake of 2.61 mL/kg/min, (ICD = 2.43, VAD = 2.2, and CRT = 3.2 mL/kg/min). These incremental increases were statistically significant when compared with the usual care or other comparison groups. Adverse event rates were very low at 1.1% to 2.2% for all CIDs. CONCLUSION: Exercise interventions tested to date in the CID population (ICD, CRT, and VAD) indicate that exercise training at moderate to high intensity is safe and effective in improving cardiopulmonary outcomes without adverse events. Future investigations should include a more diverse sample of participants, designs that include translation of exercise to routine practice, the destination therapy VAD population, and measurement of costs and patient-centered outcomes. PMID- 29465495 TI - Exercise Rehabilitation for Peripheral Artery Disease: A REVIEW. AB - PURPOSE: To summarize evidence regarding exercise therapy for people with lower extremity peripheral artery disease (PAD). METHODS: Literature was reviewed regarding optimal strategies for delivering exercise interventions for people with PAD. Randomized trial evidence and recent studies were emphasized. RESULTS: Randomized clinical trial evidence consistently demonstrates that supervised treadmill exercise improves treadmill walking performance in people with PAD. A meta-analysis of 25 randomized trials (1054 participants) concluded that supervised treadmill exercise was associated with 180 m of improvement in maximal treadmill walking distance and 128 m of improvement in pain-free walking distance compared with a control group. Three randomized trials of 493 patients with PAD demonstrated that home-based walking exercise interventions that incorporate behavioral change techniques improve walking ability in patients with PAD. Furthermore, evidence suggests that home-based walking exercise improves the 6 min walk more than supervised treadmill exercise. Upper and lower extremity ergometry also significantly improved walking endurance in PAD. The Centers for Medicare & Medicaid Services recently determined that Medicare would cover 12 wk (36 sessions) of supervised treadmill exercise for patients with PAD. CONCLUSIONS: Supervised treadmill exercise and home-based walking exercise each improve walking ability in patients with PAD. The availability of insurance coverage for supervised treadmill exercise for patients with PAD will make supervised treadmill exercise more widely available and accessible. Home-based exercise that incorporates behavioral change technique is an effective alternative for patients unwilling or unable to attend 3 supervised exercise sessions per week. PMID- 29465497 TI - Effects of beta-Blockers on Maximal Heart Rate Prediction Equations in a Cardiac Population. AB - PURPOSE: To derive specific maximal heart rate (HRmax) prediction equations for a coronary artery disease (CAD) population based upon status of beta-blocker (BB) therapy and to compare these to prior HRmax equations (Fox and Brawner-specific for CAD). METHODS: We retrospectively reviewed stress echocardiogram treadmill tests in patients with CAD, dividing subjects into 3 groups based upon BB use on test day: not prescribed BB therapy (no BB group; n = 110); held for 12 to 24 hr prior (held BB group; n = 155); and continued taking (took BB group; n = 72). RESULTS: Derived HRmax equations for our CAD population were no BB = 200 - 0.79 * age; held BB = 193 - 0.71 * age; and took BB = 168 - 0.51 * age. Achieved HRmax mean was not significantly different between held BB and no BB groups; however, HRmax in the took BB group was significantly lower. Fox and Brawner (no BB)-HRmax equations significantly overestimated (+6 and +9 mean bias) and underestimated ( 8 and -6 mean bias) achieved HRmax in no BB and held BB groups, respectively. The Brawner (no BB) equation intercept and slope were not significantly different from our CAD-held BB and no BB equations. The Brawner (on BB) equation intercept and slope were similar to our took BB equation, but greatly underestimated achieved HRmax (-17 mean bias). CONCLUSION: For patients holding BB therapy on test day, a similar CAD HRmax estimation equation to those patients never on BB can be used, comparable to the Brawner (no BB) equation. Further research is needed to determine when patients should take their BB therapy in conjunction with exercise testing. PMID- 29465498 TI - Variability in Quality of Life Outcomes Following a Pulmonary Rehabilitation Program in Patients With COPD. AB - PURPOSE: Pulmonary rehabilitation (PR) improves exercise tolerance in patients with chronic obstructive pulmonary disease. However, it is unclear why some patients do not improve quality of life during a training program. Our objective was to evaluate the differences between patients with chronic obstructive pulmonary disease who improve and those who do not improve quality of life during a pulmonary rehabilitation program. METHODS: Seventy-three patients underwent a PR program. All patients trained at 80% (legs) and 50% (arms) of their maximum load. Incremental and endurance tests, 6-min walk test, and health-related quality of life with the St George Respiratory Questionnaire (SGRQ) were measured. We subdivided the groups based on a decrease >=4 points in the pre- and post-PR SGRQ total score (G1); <4-point change in the SGRQ total score (G2); and an increase in scores >=4 points (G3). RESULTS: Exacerbation frequency (P = .004) and SGRQ total scores (P < .001) were lower in G1 and G2 than in G3. G1 (P = .0007) and G2 (P = .0005) significantly improved 6-min walk test distance. Before PR, G1 and G2 walked greater distances than G3 (P = .003); however, the difference was no longer significant after PR (P = .34). A significant load increase was seen after PR for the 3 groups (P < .05). We found a significant correlation between the SGRQ and the Charlson index (r = 0.78, P < .0001), exacerbation frequency (r = 0.72, P < .0001), and basal dyspnea index (r = -0.48, P < .0001). CONCLUSION: Patients whose quality of life did not improve after comprehensive PR presented a higher number of disease-related exacerbations with comorbidities. PMID- 29465499 TI - Pulmonary Rehabilitation in Patients With Advanced Idiopathic Pulmonary Fibrosis Referred for Lung Transplantation. AB - PURPOSE: Currently, pulmonary rehabilitation (PR) has a weak recommendation for idiopathic pulmonary fibrosis (IPF) and is often recommended for mild to moderate disease. We aimed to investigate the completion rate of PR in patients with advanced IPF, to analyze whether the severity of disease influences PR response and whether there is any difference between subjects who are able or not able to successfully complete the program. METHODS: Patients with IPF referred to lung transplantation (n = 48) were enrolled in an outpatient PR program including 3 times/wk supervised exercise training during 12 wk. A short-form 36-item health related quality-of-life (HRQL) questionnaire and 6-min walk test distance (6MWD) were evaluated before and after PR. RESULTS: We found that 64.5% of patients successfully completed PR (31/48). Baseline forced vital capacity (FVC) and lung diffusion capacity for carbon monoxide (DLCO) were 49% +/- 13% and 46% +/- 17% of predicted, respectively. There was no difference comparing those who did and did not complete PR. In the former group, 6MWD (58 +/- 63 m) and several domains of the HRQL questionnaire improved significantly. No significant association was found between markers of disease severity (FVC, DLCO, and dyspnea) and improvement in clinical outcomes. CONCLUSIONS: Two-thirds of our sample with advanced IPF referred to lung transplant successfully attended PR and improved exercise capacity and HRQL, without association with markers of disease severity. No difference was found at baseline compared with subjects who were not able to complete the program. PMID- 29465501 TI - Experience, Knowledge, and Attitudes of Child and Adolescent Psychiatrists in Belgium Toward Pediatric Electroconvulsive Therapy. AB - OBJECTIVE: The purpose of the present study was to ascertain the experience, knowledge, and attitudes of child and adolescent psychiatrists toward the use of ECT (electroconvulsive therapy) in children and adolescents in Belgium. METHODS: A questionnaire was mailed to all the members of the Flemish and Walloon Association of Child and Adolescent Psychiatrists. RESULTS: Thirty-five percent (n = 151) of the psychiatrists responded to the questionnaire. Sixty-seven percent (n = 101) rated their knowledge about ECT in children and adolescents as nil or negligible. Only one percent (n = 2) estimated their knowledge to be advanced. Fifteen percent (n = 22) were aware of a minor treated with ECT. Ten (n = 16) and thirty-one percent (n = 47) believed that ECT is a safe treatment for children and adolescents, respectively. Only six percent (n = 10) would recommend ECT for a major psychiatric disorder in a child, whereas thirty-eight percent (n = 58) for an adolescent. Fifty-three percent (n = 71) regarded ECT as a treatment of last resort. A significant correlation was identified between knowledge and attitudes toward the use of ECT in minors. Respondents with some or advanced knowledge perceived ECT as a safer and a more effective treatment option than those with negligible knowledge. Most (91%, n = 138) of the child and adolescent psychiatrists are enthusiastic to learn more about the use of ECT in minors. CONCLUSIONS: Flemish and Walloon child and adolescents psychiatrists have very little experience with using ECT in minors. They self-estimated their knowledge as negligible but are keen to learn more about this treatment option. The lack of knowledge likely explains the rare use of ECT in Belgium for children and adolescents with serious psychiatric disorders.

PMID- 29465504 TI - Letter From the Editor. PMID- 29465505 TI - Mutational Aberrations Detected in Mucinous Epithelial Ovarian Cancer of Asian Women. AB - BACKGROUND: Mucinous epithelial ovarian cancers (mEOCs) respond poorly to conventional chemotherapy and have a poor prognosis in advanced stages. The genomic landscape for mEOC in the Asian settings is ill defined. We seek to identify various mutational aberrations present in mEOC and correlate them with clinical outcomes. METHODS: A total of 199 cases of mEOC were identified from a prospectively maintained gynecologic oncology tumor database. DNA was extracted and analyzed for KRAS mutations by using Sanger sequencing. Further MassArray sequencing was performed on 45 samples. Clinicopathologic correlation was performed with the results obtained. FINDINGS: KRAS mutation status was evaluable in 124 cases. Fifty-five percent (68/124) were KRAS negative, whereas 45% (56/124) harbored a KRAS mutation, lower than that in Western populations. Successful ascertainment of both KRAS and HER2 statuses by Sanger sequencing occurred for 105 cases. The proportion of the double-positive subtype (HER2+ and KRAS positive) was 8% (8/105); double-negative subtype (HER2- and KRAS negative), 34% (36/105); and cases with mutation in either KRAS or HER2, 58% (61/105). The KRAS mutation rate was 44%, 50%, and 29% among Chinese, Indians, and Malays, respectively. There was no significant difference in overall survival (P = 0.952) or progression-free survival (P = 0.635) between KRAS-positive and KRAS-negative patients. Similar results were observed for progression-free survival (P = 0.206) and overall survival (P = 0.440) when outcomes were examined between the 4 groups based on KRAS and HER2 mutation. Patients in the double-negative mutation subgroup had higher risk for death/progression compared with patients in the other 3 mutation subgroups. Further MassARRAY multiplexed profiling was performed in patients with sufficient DNA material (n = 45) and yielded KRAS mutations (n = 16), PDGFRA mutations (n = 3), PIK3CA (n = 1) and KIT (n = 1), and HRAS, FGFR, MET, and NRAS (n = 1 each). CONCLUSIONS: Our study provides further knowledge about the mutational aberrations in mEOC in Asian populations. Neither the presence of KRAS mutation nor their correlation with HER2 mutations influenced outcomes. PMID- 29465506 TI - BRCA1, Ki67, and beta-Catenin Immunoexpression Is Not Related to Differentiation, Platinum Response, or Prognosis in Women With Low- and High-Grade Serous Ovarian Carcinoma. AB - OBJECTIVE: The purpose of this study was to compare the immunohistochemical expression of BRCA1, Ki67, and beta-catenin in women with low-grade (LGSOC) and high-grade serous ovarian carcinomas (HGSOC) and their relationship with clinicopathological features, response to platinum-based chemotherapy, and survival. METHODS: For this study, 21 LGSOC and 85 HGSOC stage I to IV cases, diagnosed and treated from 1996 to 2013 and followed-up until December 2016, were included. BRCA1, Ki67, and beta-catenin expression was assessed using tissue microarray-based immunohistochemistry. RESULTS: Women with HGSOC were significantly more likely to have advanced-stage disease (P < 0.001), higher CA125 levels (P < 0.001), postsurgery residual disease (P < 0.01), and higher rates of disease progression and recurrence (P = 0.001). The percentage of women with HGSOC whose tumors expressed Ki67 was significantly higher compared with women with LGSOC (P < 0.001). The expression of BRCA1 and beta-catenin did not differ between LGSOC and HGSOC (P = 0.12 and P = 1.00, respectively). The clinicopathological features and the response to platinum-based chemotherapy did not differ according to the BRCA1, Ki67, and beta-catenin expression in either group. In HGSOC, only International Federation of Gynecology and Obstetrics stage was independently associated with poor survival (PFS and OS). CONCLUSIONS: Ki67 expression was significantly higher in HGSOC. BRCA1 and beta-catenin expression did not differ between LGSOC and HGSOC samples. BRCA1, Ki67, and beta-catenin expression was neither related to clinicopathological features, response to platinum-based chemotherapy, nor survival. Only International Federation of Gynecology and Obstetrics stage remained associated with poor survival in women with HGSOC. PMID- 29465507 TI - BRCA1 and MAD2 Are Coexpressed and Are Prognostic Indicators in Tubo-ovarian High Grade Serous Carcinoma. AB - OBJECTIVES: The aim of this study was to investigate the relationship between BRCA1 and mitotic arrest deficiency protein 2 (MAD2) protein expression, as determined by immunohistochemistry, and clinical outcomes in epithelial ovarian carcinoma (EOC). METHODS: A tissue microarray consisting of 94 formalin-fixed paraffin-embedded EOC with fully matched clinicopathological data were immunohistochemically stained with anti-BRCA1 and anti-MAD2 antibodies. The cores were scored in a semiquantitative manner evaluating nuclear staining intensity and extent. Coexpression of BRCA1 and MAD2 was evaluated, and patient survival analyses were undertaken. RESULTS: Coexpression of BRCA1 and MAD2 was assessed in 94 EOC samples, and survival analysis was performed on 65 high-grade serous carcinomas (HGSCs). There was a significant positive correlation between BRCA1 and MAD2 expression in this patient cohort (P < 0.0001). Both low BRCA1 and low MAD2 are independently associated with overall survival because of HGSC. Low coexpression of BRCA1 and MAD2 was also significantly associated with overall survival and was driven by BRCA1 expression. CONCLUSION: BRCA1 and MAD2 expressions are strongly correlated in EOC, but BRCA1 expression remains the stronger prognostic factor in HGSC.

PMID- 29465508 TI - Impact of Hormone Receptor Status and Ki-67 Expression on Disease-Free Survival in Patients Affected by High-risk Endometrial Cancer. AB - OBJECTIVES: The aim of this study was to evaluate the immunohistochemical (IHC) expression of Ki-67, estrogen receptors alpha (ERsalpha), and progesterone receptors (PRs) in high-risk endometrial cancer patients and to assess their prognostic impact. METHODS/MATERIALS: Immunohistochemical expression of Ki-67, ERsalpha, and PRs was evaluated in primary untreated endometrial cancer. The correlation among IHC staining and risk factors of recurrence such as age, Federation International of Gynecology and Obstetrics stage, grading, depth of invasion, and metastatic spread was assessed. RESULTS: Eighty-two patients were available for the analysis. Mean +/- SD age was 65.05 +/- 10.48 years. The IHC assessment revealed a lack of ERalpha in 46.3% and of PR in 48.7% as well as a high Ki-67 in 31.7%. Loss of ERalpha and PR was associated with a significant higher rate of advanced stage of disease, a higher frequency of G3 tumors, and a myometrial invasion greater than 50%. A strong Ki-67 expression correlated with a deeper myometrial invasion. Analysis of the interrelationship between receptor immunonegativity revealed a relevant association of ERalpha immunolocalization with PR and with a high Ki-67 expression. The present study also showed that loss of ERalpha (P = 0.003), advanced Federation International of Gynecology and Obstetrics stage (P < 0.001), and high Ki-67 (P = 0.004) were independent prognostic factors of a shorter disease-free survival. Importantly, loss of ERalpha, loss of PR, and a high Ki-67 were correlated with a higher incidence of distant recurrence. CONCLUSIONS: A systematic immunohistochemistry should be a key step in the therapeutic algorithm and could contribute to the identification of high-risk tumors. PMID- 29465510 TI - Chronic Rhinosinusitis Related to Occupational Exposure: The Telemark Population Study. AB - OBJECTIVE: The aim of this study was to investigate the association between occupational exposure and chronic rhinosinusitis. METHODS: A random population from the region of Telemark, aged 16 to 50 years, answered a respiratory questionnaire including questions on chronic rhinosinusitis and exposure in the occupational environment. RESULTS: A total of 16,099/48,142 subjects responded. The prevalence of chronic rhinosinusitis was 9%. Exposure associated with chronic rhinosinusitis comprised paper dust [odds ratio (OR) 1.3, 95% confidence interval (95% CI) 1.1 to 1.5], cleaning agents (OR 1.2, 95% CI 1.0 to 1.3), metal dust (OR 1.3, 95% CI 1.1 to 1.6), animals (OR 1.2, 95% CI 1.0 to 1.5), moisture/mould/mildew (OR 1.3, 95% CI 1.1 to 1.5), and physically strenuous work (OR 1.4, 95% CI 1.2 to 1.7). CONCLUSION: Occupational exposure to paper dust, cleaning agents, metal dust, animals, moisture/mould/mildew, and physically strenuous work was independently related to having chronic rhinosinusitis. An occupational history should be reviewed when assessing patients with chronic rhinosinusitis. PMID- 29465511 TI - Prescription Dispensing Patterns Before and After a Workers' Compensation Claim: An Historical Cohort Study of Workers With Low Back Pain Injuries in British Columbia. AB - OBJECTIVE: Compare prescription dispensing before and after a work-related low back injury. METHODS: Descriptive analyses were used to describe opioid, nonsteroidal anti-inflammatory drug (NSAID), and skeletal muscle relaxant (SMR) dispensing 1 year pre- and post-injury among 97,124 workers in British Columbia with new workers' compensation low back claims from 1998 to 2009. RESULTS: Before injury, 19.7%, 21.2%, and 6.3% were dispensed opioids, NSAIDs, and SMRs, respectively, increasing to 39.0%, 50.2%, and 28.4% after. Median time to first post-injury prescription was less than a week. Dispensing was stable pre-injury, followed by a sharp increase within 8 weeks post-injury. Dispensing dropped thereafter, but remained elevated nearly a year post-injury, an increase attributable to less than 2% of claimants. CONCLUSION: These drug classes are commonly dispensed, particularly shortly after injury and dispensing is of short duration for most, though a small subgroup receives prolonged courses. PMID- 29465513 TI - Health Care Expenditures and Length of Disability Across Medical Conditions. AB - OBJECTIVE: To describe the relationship between the length of short-term disability (STD) and health care spending. METHODS: Medical claims for insured US employees on STD were evaluated to describe the distribution of disability durations and health expenditures across major diagnostic categories and common medical conditions. Correlations between health expenditures and disability durations were examined. RESULTS: The most expensive 10% of cases accounted for more than half of total health spending. The longest 10% of cases accounted for more than one-third of total disability time. Only one-third of the most expensive cases were also among the longest in duration. Disability durations were moderately correlated with medical spending and this relationship was modified by comorbid conditions and age. CONCLUSION: Psychosocial barriers, in addition to biomedical factors, should be considered to achieve optimal functional outcomes and well-being of patients. PMID- 29465512 TI - MicroRNA Changes in Firefighters. AB - OBJECTIVES: Firefighters have elevated cancer incidence and mortality rates. MicroRNAs play prominent roles in carcinogenesis, but have not been previously evaluated in firefighters. METHODS: Blood from 52 incumbent and 45 new recruit nonsmoking firefighters was analyzed for microRNA expression, and the results adjusted for age, obesity, ethnicity, and multiple comparisons. RESULTS: Nine microRNAs were identified with at least a 1.5-fold significant difference between groups. All six microRNAs with decreased expression in incumbent firefighters have been reported to have tumor suppressor activity or are associated with cancer survival, and two of the three microRNAs with increased expression in incumbent firefighters have activities consistent with cancer promotion, with the remaining microRNA associated with neurological disease. CONCLUSION: Incumbent firefighters showed differential microRNA expression compared with new recruits, providing potential mechanisms for increased cancer risk in firefighters. PMID- 29465514 TI - Smoking Cessation Is Associated With Lower Indirect Costs. AB - OBJECTIVE: This study quantified differences in indirect costs due to decreased work productivity between current and former smokers. Former smokers were further categorized by number of years since quitting to assess corresponding differences. METHODS: Data on employed individuals were obtained from the 2013 US National Health and Wellness Survey (NHWS; N = 75,000). Indirect costs were calculated for current smokers and former smokers from weekly wages based on age and sex. RESULTS: The annual total indirect costs for current smokers were $1327.53, $1560.18, and $1839.87 higher than for those who quit 0 to 4 years, 5 to 10 years, and more than or equal to 11 years prior, respectively. There were no significant differences in mean total indirect costs between the former smoker groups. CONCLUSIONS: Current smokers showed significantly higher total annual indirect costs compared with former smokers, independently of the number of years since quitting smoking. PMID- 29465515 TI - Metabolic Rate during a Cognitive Vigilance Challenge at Alternative Workstations. AB - OBJECTIVE: The aim of this study was to compare energy expenditure (EE, kcal/min) at three workstations during an attention-demanding cognitive function task (Test of Variables of Attention or TOVA). Workstations included the seated desk (SIT), standing desk (STAND), and seated workstation designed to promote spontaneous movement (SWING). METHODS: Adult males (n = 11) and females (n = 13) were assessed for EE using VO2 and VCO2 per quarter of the 22-min TOVA. RESULTS: Average EE were 1.39 +/- 0.06 (SIT), 1.55 +/- 0.08 (SWING), and 1.44 +/- 0.08 (STAND). Main effects (P < 0.05) were seen for workstation (SWING, STAND > SIT), and quarter of TOVA (Q2 < Q1,Q3,Q4). TOVA errors and response times were not different for workstations but increased for Q3 and Q4. CONCLUSION: Spontaneous movement at an alternative workstation elevated EE 10% to 11% compared with sitting and could increase daily nonexercise activity thermogenesis without diminishing mental attention to desk work.

PMID- 29465516 TI - The Correlation of a Corporate Culture of Health Assessment Score and Health Care Cost Trend. AB - OBJECTIVE: Employers that strive to create a corporate environment that fosters a culture of health often face challenges when trying to determine the impact of improvements on health care cost trends. This study aims to test the stability of the correlation between health care cost trend and corporate health assessment scores (CHAS) using a culture of health measurement tool. METHODS: Correlation analysis of annual health care cost trend and CHAS on a small group of employers using a proprietary CHAS tool. RESULTS: Higher CHAS scores are generally correlated with lower health care cost trend. For employers with several years of CHAS measurements, this correlation remains, although imperfectly. CONCLUSION: As culture of health scores improve, health care costs trends moderate. These findings provide further evidence of the inverse relationship between organizational CHAS performance and health care cost trend.

PMID- 29465536 TI - Primary cutaneous amyloidosis associated with autoimmune hepatitis-primary biliary cirrhosis overlap syndrome and Sjogren syndrome: A case report. AB - RATIONALE: Primary cutaneous amyloidosis (PCA) is a localized skin disorder characterized by the abnormal deposition of amyloid in the extracellular matrix of the dermis. The association between PCA and other diseases, although rare, has been documented for various autoimmune diseases. PCA associated with autoimmune hepatitis-primary biliary cirrhosis (AIH-PBC) overlap syndrome and Sjogren syndrome (SS) has not been previously reported in the literature. PATIENT CONCERNS: A 50-year-old woman presented with progressive abnormal liver enzyme levels and was referred to our department. DIAGNOSES: Due to the patient's symptoms, laboratory test results, radiographic findings, and pathologic results, she was diagnosed with PCA associated with AIH-PBC overlap syndrome and SS. INTERVENTIONS: She was subsequently treated with a combination of ursodeoxycholic acid (UDCA), prednisone, and azathioprine. OUTCOMES: While this treatment can achieve therapeutic success, it cannot prevent complications from cirrhosis. This patient remains alive but experienced an emergent gastrointestinal hemorrhage. LESSONS: While we acknowledge that this is a single case, these findings extend our knowledge of immunological diseases associated with PCA and suggest a common, immune-mediated pathogenic pathway between PCA, AIH-PBC overlap syndrome, and SS. After 12 years of follow up, clinical manifestations have developed, and these autoimmune diseases have progressed. The combination of UDCA, prednisone, and azathioprine can achieve therapeutic success but cannot prevent disease progression. Routine follow up for this patient is necessary to document disease progression. PMID- 29465538 TI - Enhanced recovery after surgery (ERAS) programs for esophagectomy protocol for a systematic review and meta-analysis. AB - BACKGROUND: Esophageal cancer is one of the worst malignant digestive neoplasms with poor treatment outcomes. Esophagectomy plays an important role and offers a potential curable chance to these patients. However, esophagectomy with radical lymphadenectomy is known as one of the most invasive digestive surgeries which are associated with high morbidity and mortality. The enhanced recovery after surgery (ERAS) protocol is a patient-centered, surgeon-led system combining anesthesia, nursing, nutrition, and psychology, which is designed for reducing complications, promoting recovery, and improving treatment outcomes. This systematic review and meta-analysis is aiming at how beneficial, and to what extent ERAS really will be. METHODS: A systematic literature search will be performed through January 2018 using MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, and Google Scholar for relevant articles published in any language. Randomized controlled trials, prospective cohort studies, and propensity-matched comparative studies will be included. All meta-analyses will be performed using Review Manager software. The quality of the studies will be evaluated using the guidelines listed in the Cochrane Handbook. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses statements will be followed until the findings of the systematic review and meta-analysis are reported. RESULTS: The results of this systematic review and meta-analysis will be published in a peer-reviewed journal. CONCLUSION: Our study will draw an objective conclusion of the comparisons between ERAS and conventional care in aspects of perioperative outcomes and provide level I evidences for clinical decision makings. PMID- 29465537 TI - Laparoscopic gastrectomy for elderly patients with gastric cancer: A systematic review with meta-analysis. AB - BACKGROUND: Laparoscopic gastrectomy (LG) has been widely applied in patients with gastric cancer (GC). However, the safety and application value of LG in elderly patients with GC was still unclear. In this study, we aimed to evaluate the feasibility and safety of LG for elderly patients with GC using the meta analysis. METHODS: Studies comparing elderly patients and nonelderly patients who underwent LG for GC were reviewed and collected from the PubMed, EBSCO, Cochrane Library, and EMBASE. Outcomes such as operative results, postoperative recovery, and morbidity were compared and analyzed. The Review Manager 5.3 was used to portray the weighted mean difference (WMD) and odds ratio (OR) with a 95% confidence interval (CI). RESULTS: Eleven observational studies with a total of 3275 patients were included. Compared with nonelderly patients, elderly patients had shorter operation time (WMD -10.46; 95% CI -17.06 to -3.86; P = .002), less retrieved lymph nodes (WMD -2.34; 95% CI -3.77 to -0.92; P = .001), delayed time to first flatus (WMD 0.31; 95% CI 0.10-0.51; P = .003), longer postoperative hospital stays (WMD 1.06; 95% CI 0.07-2.05; P = .04), higher risk for overall postoperative complication (OR 1.34; 95% CI 1.08-1.67; P = .009), nonsurgical postoperative complication (OR 1.98; 95% CI 1.24-3.15; P = .004), and postoperative pulmonary complication (OR: 3.09; 95% CI 1.68-5.68; P < .001). There was no significance between nonelderly patients and elderly patients regarding the estimated blood loss, incidences of surgical postoperative complication, surgical site infection, and ileus (P > .05). CONCLUSION: Outcomes of LG for elderly patients were comparable to those in nonelderly patients. Age alone should not preclude LG in elderly patients.

PMID- 29465539 TI - Different utilization of intensive care services (ICSs) for patients dying of hemorrhagic and ischemic stroke, a hospital-based survey. AB - The intensive care service (ICS) saves lives and rescues the neurological function of stroke patients. We wondered the different utilization of ICS for patients with ischemic and hemorrhagic stroke, especially those who died within 30 days after stroke.Sixty-seven patients died during 2011 to 2015 due to acute stroke (42 due to intracranial hemorrhage [ICH]; 25 due to cerebral infarct [CI]). The durations of hospital stay (hospital staying days [HSDs]) and ICS staying days (ISDs) and codes of the do-not-resuscitate (DNR) were surveyed among these medical records. Statistics included chi-square and descriptive analyses.In this study, CI patients had a longer HSD (mean 14.3 days), as compared with ICH patients (mean 8.3 days); however, the ICH patients had a higher percentage of early entry within the first 24 hours of admission into ICS than CI group (95.1% vs 60.0%, P = .003). A higher rate of CI patients died in holidays or weekends than those with ICH (44.0% vs 21.4%, P = .051). DNR, requested mainly from direct descendants (children or grandchildren), was coded in all 25 CI patients (100.0%) and 38 ICH patients (90.5%). More cases with early DNR coded within 24 hours after admission occurred in ICH group (47%, 12% in CI patients, P = .003). None of the stroke patient had living wills. Withhold of endotracheal intubation (ETI) occurred among CI patients, more than for ICH patients (76.0% vs 18.4%, P < .005).In conclusion, CI patients longer HSD, ISD, higher mortality within holidays or weekends, and higher ETI withhold; but less percentage of ICS utilization expressed by a lower ISD/HSD ratio. This ICS utilization is a key issue of medical quality for stroke care.

AB - RATIONALE: To report a case of late spontaneous reattachment of Descemet membrane (DM) detachment after deep anterior lamellar keratoplasty (DALK). PATIENT CONCERNS: A 50-year-old woman with stromal corneal scarring underwent a DALK with the big bubble technique. The DM detachment and double anterior chamber were observed on the first day after operation. DIAGNOSES: Descemet membrane detachment after deep anterior lamellar keratoplasty [Oculus Dexter (OD), indicates right eye]. INTERVENTIONS: Sterile air injection was unsuccessful. Conservative observation was performed. OUTCOMES: During the follow-up, the donor cornea kept transparent and no edema was observed. The DM reattached spontaneously at the fifth months post-DALK. LESSONS: The present case suggests that the retained host DM may result in DM detachment after DALK. For the DM detachment without roll rim, the detachment may spontaneously reattach in several months after surgery. PMID- 29465542 TI - The small bowel diseases detected by capsule endoscopy in patients with chronic abdominal pain: A retrospective study. AB - Chronic abdominal pain (CAP) remains a particular challenge because of its complicated causes, especially when the disorders involve the small bowel, where it is quite difficult to intubate the flexible endoscopes. This study was to investigate the small bowel diseases detected by capsule endoscopy (CE) in CAP patients to evaluate the role of CE on CAP, and analyzed the relationship among the clinical characteristics of CAP patients and the positive rates of CE findings to search for the indications of CE for CAP patients.This retrospective study included 341 patients with CAP defined as recurrent abdominal pain for no <3 months. Each patient underwent CE after a negative diagnostic work-up. All CE images were reviewed by 3 gastroenterologists independently. The positive findings were defined as abnormal findings in the small bowel that might have been the causes of CAP. The final diagnosis was confirmed by CE findings, clinical features, histopathology, and a response to the treatment during the follow-up for at least 3 months after CE.The overall positive rate of CE findings was 28.15% (96/341). The positive rate in CAP-A (CAP with associated symptoms) group was significantly higher than that in CAP-O (CAP only) group (33.16% vs 21.38%, P = .017). Multivariate logistic regression analysis revealed that weight loss (odds ratio [OR] = 2.827, 95% confidence interval (CI) = 1.938-4.926), hypoalbuminemia (OR = 6.142, 95%IC = 4.129-8.274), elevated erythrocyte sedimentation rate (ESR) (OR = 4.025, 95%IC = 3.178-6.892), or increased C reactive protein (CRP) (OR = 7.539, 95%CI = 5.365-11.723) were significantly associated with high positive rates. On follow-up, final diagnosis was confirmed in 56 of 69 (81.16%) patients with positive CE findings. About half of these patients (46.38%, 32/69) were diagnosed as inflammatory diseases, including Crohn disease (12), tuberculosis (5), NSAID enteropathy (4), etc. Tumors were proved in 21.74% (15/69) patients, including malignant in 7 cases and benign in 8 cases. Parasitosis was found in 9 (13.04%) patients.This study suggests that CE may be helpful for CAP patients to detect the small bowel diseases, half of which were comprised of inflammatory diseases. Besides, weight loss, hypoalbuminemia, elevated ESR, or increased CRP may be regarded as the indications of CE for CAP patients. PMID- 29465544 TI - The choose of different surgical therapies of hepatic alveolar echinococcosis: A single-center retrospective case-control study. AB - The aim of this study was to evaluate different surgical therapies for hepatic alveolar echinococcosis in different clinical stages.We analyze the clinical data of 115 patients who received surgical treatment in West China Hospital from January 2004 to June 2016. Among these patients, 77 cases underwent radical hepatic resection (group A, n = 77); 17 cases underwent palliative resection (group B, n = 17), and 21 cases underwent liver transplantation (group C, n = 21) with 12 cases of orthotopic liver transplantation and 9 cases of liver autotransplantation.The postoperative complication rate of radical hepatic resection group was 13.0% (10/77), which is statistically significant (P < .05) than the rate of palliative resection group 29.4% (5/17) or liver transplantation group 23.8% (5/21). The follow-up period ranged from 1 to 72 months. The overall median survival rate of radical resection was 72/77, higher than the rate of palliative group (12/17) or transplantation group (17/21), which was also statistically significant (P < .01).In our study, we believe in that all stages of hepatic alveolar echinococcosis should take active surgical interventions, and radical hepatic resection should be considered as the first-choice treatment for early stage of alveolar echinococcosis, while palliative surgery is still helpful to relieve symptoms and improve the life quality for advanced patients. Liver transplantation might also be an alternative option for the late-stage hepatic alveolar echinococcosis.

PMID- 29465545 TI - Metformin reduces the risk of cancer in patients with type 2 diabetes: An analysis based on the Korean National Diabetes Program Cohort. AB - The epidemiological literature suggests that insulin resistance, hyperinsulinemia, and increased levels of insulin-like growth factors place patients with type 2 diabetes mellitus (T2DM) at greater risk of cancer. The association between cancer incidence and the use of antidiabetic medications in patients with T2DM has been recently examined. There have been conflicting reports regarding an association between metformin and cancer risk. The aim of this study was to investigate the relationship between metformin use and the incidence of cancer in Koreans with T2DM.Data from The Korean National Diabetes Program (KNDP, 2006-2014), a nationwide, large-scale, prospective, multicenter cohort study in Korea, were used to study patients with T2DM. Patients >=30 years old whose complete medical records were available were included in this study. Patients with a history of any cancer on KNDP registration or those who had been diagnosed with any type of cancer within 1 year of metformin use were excluded. Survival curves with respect to the incidence of cancer were plotted using the Kaplan-Meier method. Hazard ratios and 95% confidence intervals for cancer were estimated in a Cox proportional hazards regression analysis.During a mean 5.8 years of follow-up, 164 of the 1918 study patients (335 metformin nonusers and 1583 metformin users) developed cancer. The incidence per 1000 person-years was 21.8 in metformin nonusers and 13.2 in metformin users. Metformin users had a reduced risk of cancer, even after adjustment for demographic characteristics, metabolic parameters, diabetic complications, and other antidiabetic medications (hazard ratio 0.513, 95% confidence interval 0.318-0.826, P = .0060). Subgroup analysis of metformin users showed a reduced risk of cancer in males, patients < 65 years of age, patients with a T2DM duration < 5 years, nonobese patients, nonsmokers, and good glycemic control group.This large-scale, prospective, multicenter cohort study demonstrated an association between metformin use and reduced cancer risk in patients with T2DM.

PMID- 29465549 TI - Cardiorespiratory parameters and glycated hemoglobin of patients with type 2 diabetes after a rehabilitation program. AB - INTRODUCTION: Cardiovascular autonomic dysfunction reflex of the pathophysiology of diabetes mellitus (DM) favors an increase in morbidity and mortality related to cardiovascular events, and for this reason has been one of the most studied clinical entities. METHOD: An experimental study of a randomized clinical trial type was therefore proposed to analyze the hemodynamic and glycemic response after the practice of a rehabilitation program in patients with type 2 diabetes mellitus (T2DM). In this clinical trial the patients will initially be submitted to an evaluation protocol that consists of assessing blood pressure, heart rate, Borg scale, respiratory rate, oxygen saturation, distance traveled through the 6 minute walk test, quality of life questionnaire, Pittsburgh sleep quality questionnaire, and still glycated hemoglobin and heart rate variability through the cardiofrequency meter. After careful evaluation of the patients, they will be submitted to a metabolic rehabilitation program composed of aerobic and resisted exercises, performed for 12 weeks, in 3 weekly meetings of 60 minutes each. With such evaluations, it will be possible to construct with evidence that it is possible to work safer metabolic rehabilitation programs in patients with T2DM or other diseases that generate cardiovascular risks, guaranteeing them an improvement in cardiorespiratory fitness, hemodynamic and glycemic variables, allowing improvement of the quality of life. ETHICS AND DISSEMINATION: The protocol is approved by the host institution's ethics committee under the number 1.616.721. Results will be disseminated via peer-reviewed journal articles and conferences. This clinical trial is registered at ClinicalTrials.gov identifier: NCT3094767. PMID- 29465550 TI - Clinical significance of computed tomography-detected ascites in gastric cancer patients with peritoneal metastases. AB - Patients with peritoneal metastases (PM) are generally considered incurable; therefore, the presence of PM is a critical factor in deciding between palliative surgery and curative resection as a therapeutic strategy. Previous studies have not determined the predictive value of ascites detected on computed tomography (CT) for the presence of PM. We aimed to analyze the factors that are associated with PM in patients with CT-detected ascites.A total of 2207 consecutive patients who were diagnosed with gastric cancer between 2004 and 2013 were identified. Eleven patients with liver cirrhosis or chronic renal insufficiency with ascites and 57 patients who received previous treatment were excluded. Ninety-eight patients who had definite evidence of distant metastasis or PM on CT and 64 patients who did not undergo surgery were excluded. A total of 91 patients were enrolled in the study to analyze the association between CT-detected ascites and surgically confirmed PM.Seventy-six patients underwent curative resection and 15 patients underwent palliative surgery. Twelve patients exhibited peritoneal seeding and 37 patients showed regional lymph node metastasis. Regional lymph node metastasis, advanced gastric cancer, undifferentiated pathology, and the amount of ascites were significantly associated with PM. Multivariable logistic regression analysis identified the amount of ascites to be an independent risk factor for the presence of PM.Regional lymph node metastasis, advanced gastric cancer, undifferentiated pathology, and the amount of ascites were associated with PM. The amount of ascites was found to be an independent risk factor for PM. PMID- 29465551 TI - Sirolimus alternative to blood transfusion as a life saver in blue rubber bleb nevus syndrome: A case report. AB - RATIONALE: Blue rubber bleb nevus syndrome (BRBNS) is a rare disease characterized by multiple venous malformations. The gastrointestinal bleeding and secondary iron deficiency anemia are the most common complications. There are currently no effective treatments for BRBNS. Here, we report a case of successful treatment with a small dose of sirolimus of a BRBN patient with a de novo gene mutation. PATIENT CONCERNS: A 12-year-old female was admitted to our hospital with multiple hemangiomas for 12 years. The patient often displayed melena; she recently received transfusion of 2 units of red blood cells once every 2 weeks. Multiple fist-sized hemangiomas were piled up on both sides and back of the neck, and were also noted on the arms, legs, chest, back, and on the tip of the tongue. The laboratory findings demonstrated severe anemia. Blood sample sequencing detected a heterozygous de novo mutation c.2545C > Tin the TEK gene. DIAGNOSES: Based on these findings, final diagnosis of Blue rubber bleb nevus syndrome (BRBNS) was made. INTERVENTIONS: After the diagnosis, low-dose sirolimus was orally administered. OUTCOMES: The patient's hemoglobin was increased after treatment with sirolimus for 1 month. Since the initial treatment with sirolimus, she had not received any blood transfusions. The skin and mucosal hemangioma decreased significantly, and new digestive tract hemorrhage, muscle hematoma, or adverse drug reactions were not observed. LESSONS: we report a case of a mutation in exon 15 of the TEK gene leading to BRBN. It was successfully treated with a small dose of sirolimus as an alternative to blood transfusion in order to save the of BRBN patient's life. PMID- 29465552 TI - Diagnostic accuracy of magnetic resonance imaging, transvaginal, and transrectal ultrasonography in deep infiltrating endometriosis. AB - To determine the diagnostic accuracy of pelvic magnetic resonance imaging (MRI), transvaginal sonography (TVS), and transrectal sonography (TRS) in diagnosis of deep infiltrating endometriosis (DIE).This diagnostic accuracy study was conducted during a 2-year period including a total number of 317 patients with signs and symptoms of endometriosis. All the patients were evaluated by pelvic MRI, TVS, and TRS in the same center. The criterion standard was considered to be the laparoscopy and histopathologic examination.Of 317 patients being included in the present study, 252 tested positive for DIE. The sensitivity, specificity, positive predictive value, and negative predictive value of TVS was found to be 83.3%, 46.1%, 85.7%, and 41.6%, respectively. These variables were 80.5%, 18.6%, 79.3%, and 19.7% for TRS and 90.4%, 66.1%, 91.2%, and 64.1% for MRI, respectively. MRI had the highest accuracy (85.4%) when compared to TVS (75.7%) and TRS (67.8%). The sensitivity of TRS, TVS, and MRI in uterosacral ligament DIE was 82.8%, 70.9%, and 63.6%, respectively. On the contrary, specificity had a reverse trend, favoring MRI (93.9%, 92.8%, and 89.8% for TVS and TRS, respectively).The results of the present study demonstrated that TVS and TRS have appropriate diagnostic accuracy in diagnosis of DIE comparable to MRI. PMID- 29465553 TI - Prognostic role of platelet to lymphocyte ratio in pancreatic cancers: A meta analysis including 3028 patients. AB - BACKGROUND: Platelet to lymphocyte ratio (PLR) was recently reported being associated with the prognosis of pancreatic cancer (PC), but the prognostic value of PLR in pancreatic cancer remains inconsistent. We conduct a meta-analysis to evaluate the prognostic role of PLR in patients with PC. METHODS: PubMed, Embase, Cochrane Library, and Web of Science were systematically searched for eligible studies which investigated the relationship between PLR and clinical outcome of patients with pancreatic cancer. Pooled hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated to evaluate the prognostic role of PLR in overall survival (OS) and progression-free survival (PFS)/time to progression (TTP). RESULTS: A total of 16 studies comprising 3028 patients with PC were enrolled in this meta-analysis. Pooled analysis demonstrated that elevated PLR predicted a poor OS (HR = 1.22, 95% CI: 1.09-1.36, P < .001). Prognostic role of PLR on OS were significant in subgroup of Asians (HR = 1.22, 95% CI: 1.11-1.34, P < .001), patients treated with chemotherapy (HR = 1.18, 95% CI: 1.04-1.35, P = .01) and mixed methods (HR = 1.29, 95% CI: 1.07-1.57, P = .009), American joint committee on cancer (AJCC) stage of III-IV (HR = 1.22, 95% CI: 1.09-1.36, P < .001), pathological subtype of pancreatic adenocarcinoma (HR = 1.21, 95% CI: 1.08-1.36, P = .001), and cut-off value of PLR >=160 (HR = 1.48, 95% CI: 1.25-1.75, P < .001). CONCLUSIONS: An elevated PLR is associated with unfavorable overall survival in patients with pancreatic cancer. PMID- 29465554 TI - Case report: Purulent transformation of granulocytic sarcoma: An unusual pattern of differentiation in acute promyelocytic leukemia. AB - RATIONALE: Acute promyelocytic leukemia (APL) is a curable subtype of acute myeloid leukemia. APL is currently treated with combination of all-trans retinoic acid (ATRA) and arsenic trioxide (ATO) resulting in the induction of apoptosis and differentiation of the leukemic cells. Differentiation syndrome (so-called ATRA syndrome) is the main life-threatening complication of induction therapy with these differentiating agents. PATIENT CONCERNS: Herein, we report the case of a 49-year-old woman diagnosed with APL with, concomitantly, a bulky cutaneous lesion of 10 cm diameter with a red-to-purple background and a necrotic center, localized on her abdomen. DIAGNOSES: After 10 days of treatment, the cutaneous lesion became purulent. Fluorescence in situ hybridization (FISH) analysis performed on this pus confirmed the presence of malignant features in the involved granulocytes proving their origin from the differentiation of leukemic APL cells, as all the analyzed nuclei showed 2 promyelocytic leukemia (PML) retinoic acid receptor-a (RARA) fusions signals. INTERVENTION: The association by ATRA and ATO was continued. OUTCOME: Eventually, the evolution was favorable with healing in three weeks. LESSONS: This case report therefore highlights the differentiation phenomenon of promyelocytic blasts within promyelocytic sarcoma with the ATRA-ATO combination and the efficacy of this drug association in resolving both the malignant sarcoma and a secondary local infection. PMID- 29465555 TI - Two cases of Dieulafoy lesions of the bronchus with novel comorbid associations and endobronchial ablative management. AB - RATIONALE: Dieulafoy lesions are aberrantly large submucosal arteries most frequently associated with gastrointestinal hemorrhage. They are rarely identified in the bronchial submucosa and can cause massive hemoptysis. PATIENT CONCERNS: We present three episodes of massive hemoptysis in two patients, the first with comorbid Alagille syndrome including multiple cardiac and pulmonary vascular abnormalities and the second with thyroid cancer metastatic to the mediastinum. DIAGNOSES: All episodes were due to Dieulafoy lesions of the bronchus based on bronchoscopic appearance. INTERVENTIONS: Bronchoscopic ablation using Nd:YAP laser was attempted both patients. OUTCOMES: Nd:YAP laser successfully ablated the Dieulafoy lesion in the first case with long-term relief from recurrent hemoptysis. The first episode in the second patient responded to bronchial artery embolization; laser ablation of a different Dieulafoy lesion responsible for the second episode was unsuccessful but additional bronchial artery embolization has provided relief from further episodes. LESSONS: Bronchoscopic ablation of Dieulafoy lesions of the bronchus can provide durable relief from recurrent symptoms. Clinical and anatomical features should be considered carefully before intervention, which should only be attempted by experienced operators with appropriate ancillary support available. PMID- 29465556 TI - Identification of potential target genes for ankylosing spondylitis treatment. AB - This study aimed to identify the potential target genes for the treatment of ankylosing spondylitis (AS).Dataset GSE25101 was downloaded from Gene Expression Omnibus, including 16 AS and 16 normal control blood samples. Differentially expressed genes (DEGs) were identified using unmatched t-test in limma package with adjusted P < .05. Gene ontology-biological process (GO-BP) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were conducted using multifaceted analysis tool for human transcriptome. Protein-protein interaction (PPI) network was constructed using STRING and Cytoscape, and module analysis was performed using MCODE plug-in. Webgestal was utilized to predict transcriptional factor (TF)-microRNA-target network and Comparative Toxicogenomics Database (CTD) was applied to predict chemical-target network.A total of 334 DEGs were identified, including 136 upregulated genes and 198 downregulated genes. According to STRING, a PPI network was constructed and 1 significant clustered module was screen out with score = 6.33. MAPK7 (degree = 11) and NDUFS4 (degree = 10) were 2 important nodes in PPI network, and both of them were significantly enriched in cAMP mediated signaling pathway (P = 2.02E-02). MAPK7 could be regulated by NFY. Both MAPK7 and NDUFS4 were 2 potential targets for Indomethacin.MAPK7 and NDUFS4 played important roles in the pathogenesis of AS via cAMP mediated signaling pathway. Both of them could be targeted by Indomethacin. PMID- 29465557 TI - Follow-up of blood glucose distribution characteristics in a health examination population in Chengdu from 2010 to 2016. AB - The worldwide prevalence and incidence of diabetes and obesity are increasing in pandemic proportions. Thus, regular health examination is an important way for early detection of diabetes and glucose intolerance. The present study aims to detect the blood glucose distribution characteristics of the participants in the Health Examination Center at West China Hospital, Sichuan University from 2010 to 2016.A prospective cohort included 9168 Chinese participants, aged 18 years or more, who had available information on fasting blood glucose concentrations at the start of the study (2010). Examination surveys were conducted every year from 2010 to 2016. Cases having serum level of fasting blood glucose between 2.2 and 6.1 mmol/L were considered as normality, while serum level of fasting blood glucose < 2.2 or higher than 6.2 mmol/L were considered as abnormality.The percentage of participants having normal level of glucose was gradually reduced both in males and females from 2010 to 2016, by which the percentage of males having normal level of glucose was significantly lower than that in females. Moreover, the mean level of glucose was significantly increased from 2010 to 2016 both in males and females overall, and the mean level of glucose was higher in males compared with that in females every year. Furthermore, we showed that the level of glucose was gradually increased year by year in each age group, and the level of glucose was higher in aged cases compared with the young population.The study population in the current study showed higher levels of glucose with ages increasing, and males indicated higher expression of glucose than that in females. Some preventive action may be adopted early and more attention can be paid to this health-examination population. PMID- 29465558 TI - Analysis of clinical characteristics and treatment of immunoglobulin G4 associated cholangitis: A retrospective cohort study of 39 IAC patients. AB - Immunoglobulin (Ig)G4-associated cholangitis (IAC) is one of the common organ manifestations of IgG4-related systemic disease (ISD). IAC and autoimmune pancreatitis (AIP) may mimic sclerosing cholangitis, cholangiocarcinoma, or pancreatic carcinoma. Diagnosis is based on a combination of clinical, biochemical, radiological, and histological findings.To study the clinical presentation of and treatment strategy for IAC, we reviewed clinical, serologic, and imaging characteristics, as well as treatment response, in 39 patients with IAC. The majority of patients were men (82%). Clinical features on presentation included obstructive jaundice in 26 patients (67%) and abdominal pain in 20 (51%). Positive IgG4 immunostaining was seen in 27 patients. The median serum IgG4 level before treatment was 769.4 mg/dL (range, 309.1-1229.7 mg/dL). After the steroid therapy, the median serum IgG4 level in 23 patients was 247.0 mg/dL (range, 139.0-355.0 mg/dL). Cholangiograms were available in 36 (92%) patients. Stenosis of the lower part of the common bile duct was found in 26 of 39 patients. Stenosis was diffusely distributed in the intra- and extrahepatic bile ducts in 14 of 39 patients. Additionally, strictures of the bile duct were detected in the hilar hepatic lesions in 27 of 39 patients. AIP was the most frequent comorbidity (35/39 in this study) of IAC. Other affected organs included eyes (n = 6), salivary glands (sialadenitis, n = 10), lymph nodes (mediastinal and axillary, n = 3), kidneys (n = 2), and the retroperitoneum (retroperitoneal fibrosis, n = 2).Regarding treatment, 29 patients were treated with steroids, of whom one underwent pancreatoduodenectomy, and one underwent choledochojejunostomy. Eight patients were treated with biliary stents. The remaining 19 patients took prednisolone alone. Eight patients achieved spontaneous resolution. Four patients with suspected pancreatic cancer or cholangiocarcinoma underwent surgery, including 2 patients who also received postoperative steroids. All patients were regularly followed up for 9 to 36 months. Only 2 patients in the steroids treatment group relapsed to manifest obstructive jaundice and high serum IgG4 levels. These 2 patients were treated with steroids and biliary stents, resulting in complete remission.We also review the diagnostic and therapeutic management and discuss recent pathophysiological findings, which might aid in understanding the molecular mechanisms contributing to IAC and other manifestations of IgG4-related diseases (IgG4-RD). Biomarkers that are more accurate are needed to correctly diagnose IAC and prevent misdiagnoses and unnecessary therapeutic interventions. PMID- 29465559 TI - Cardiac rehabilitation in acute myocardial infarction patients after percutaneous coronary intervention: A community-based study. AB - BACKGROUND: Acute myocardial infarction (AMI) is one of the leading causes of death and physical disability worldwide. However, the development of community- based cardiac rehabilitation (CR) in AMI patients is hysteretic. Here, we aimed to evaluate the safety and efficacy of CR applied in the community in AMI patients who underwent percutaneous coronary intervention (PCI). METHODS: A total of 130 ST-segment elevated myocardial infarction (STEMI) patients after PCI were randomly divided into 2 groups in the community, rehabilitation group (n = 65) and control group (n = 65). Cardiac function, a 6-minute walk distance, exercise time and steps, cardiovascular risk factors were monitored respectively and compared before and after the intervention of 2 groups. The software of EpiData 3.1 was used to input research data and SPSS16.0 was used for statistical analysis. RESULTS: After a planned rehabilitation intervention, the rehabilitation group showed better results than the control group. The rehabilitation group had a significant improvement in recurrence angina and readmission (P < .01). Left ventricular ejection fraction (LVEF) of rehabilitation group showed improvement in phase II (t = 4.963, P < .01) and phase III (t = 11.802, P < .01), and the New York Heart Association (NYHA) classification was recovered within class II. There was a significant difference compared with before (Z = 7.238, P < .01). Six minutes walking distance, aerobic exercise time, and steps all achieved rehabilitation requirements in rehabilitation group in phase II and III, there existed distinct variation between 2 phases. Rehabilitation group had a better result in cardiovascular risk factors than control group (P < .05). CONCLUSION: Community-based CR after PCI through simple but safe exercise methods can improve the AMI patient's living quality, which includes increasing cardiac ejection fraction, exercise tolerance, and physical status. It must be emphasized that the good result should be established by the foundation of close cooperation between cardiologists and general practitioners, also the importance of cooperation of patients and their families should not be ignored. The rehabilitation program we used is feasible, safe, and effective. PMID- 29465560 TI - Olanzapine and haloperidol for the treatment of acute symptoms of mental disorders induced by amphetamine-type stimulants: A randomized controlled trial. AB - BACKGROUND: This study aimed to compare olanzapine and haloperidol efficacies in the treatment of acute psychiatric symptoms due to amphetamine-type stimulants (ATSs). METHODS: The Zelen II design method was used; 124 patients with acute mental disorders due to amphetamine were randomly divided into olanzapine group (n = 63) and haloperidol group (n = 61). Then, a 4-week open-label medical therapy was performed. Clinical Global Impression Scale Item 2 was employed to evaluate the onset time; meanwhile, Brief Psychiatric Rating Scale (BPRS) was used at baseline and at posttreatment weeks 1, 2, and 4. Moreover, adverse reactions during the treatment were recorded. RESULTS: Onset time in the olanzapine group was significantly earlier than in the haloperidol group; BPRS scores in the olanzapine group were significantly lower than haloperidol group values at 1 and 2 weeks of treatment. The overall effective rates had no statistically significant difference. CONCLUSION: Short-term olanzapine and haloperidol treatments had equivalent efficacies in the treatment of acute symptoms of mental disorders due to ATSs; however, olanzapine administration resulted in relatively earlier disease onset, with less adverse reactions. PMID- 29465561 TI - Cross-sectional study of CD4: CD8 ratio recovery in young adults with perinatally acquired HIV-1 infection. AB - Antiretroviral therapy (ART) has improved survival into adulthood for young people with perinatally acquired HIV-1 (yp-PaHIV), but long-term prognosis remains unclear. We hypothesized that on-going immune activation, reflected in the failure of CD4:CD8 ratio normalization would be observed in yp-PaHIV, despite ART.A cross-sectional study of routinely collected clinical data from a cohort of yp-PaHIV (>=16 years).Data were collected from records of individuals attending a specialist clinic for yp-PaHIV transitioning to adult care. CD4:CD8 ratio and proportion with CD4:CD8 ratio >=1, demographic data and viral parameters, including HIV-1 viral load (VL) and human cytomegalovirus (CMV) IgG, were analyzed with IBM SPSS Statistics v22.A total of 115 yp-PaHIV, median (IQR) age 22.0 (20.0-24.0) years, were studied, of whom 59 were females, and the majority were Black African 75/115 (65.2%). Where measured, CMV antibodies were frequently detected (71/74, 95.9%) and CMV IgG titre was inversely associated with CD4:CD8 ratio, (Rho -0.383, P = .012). Of those taking ART, 69 out of 90 (76.7%) yp-PaHIV had suppressed HIV viremia (<50 RNA copies/mL) and recovery of CD4:CD8 ratio to >=1 was seen in 26 out of 69 (37.7%) with suppressed HIV viremia. Persistence of low CD4:CD8 ratio was observed even in those with a CD4 count >=500 cells/MUL, where 28/52 (53.8%) had a CD4:CD8 ratio <1. Of those with suppressed viremia, the median (IQR) age for starting ART was 8.0 (5.0-12.8) years and CD4:CD8 ratio was inversely associated with age at ART start, Rho -0.348, (P = .028).In this cohort of yp-PaHIV, despite lifelong HIV infection and widespread CMV coinfection, CD4:CD8 ratio recovery rate was comparable to adults treated in acute infection. Where persistence of CD4:CD8 ratio abnormality was observed, on-going immune activation may have significance for non-AIDS outcomes. Taken together our findings indicate immune resilience to be a feature of these adult survivors of perinatally acquired HIV infection, which can be supported with early antiretroviral therapy. PMID- 29465562 TI - Subacute onset leukodystrophy and visual-spatial disorders revealing phenylketonuria combined with homocysteinmia in adulthood: A case report. AB - RATIONALE: Phenylketonuria (PKU) is a metabolic disorder, which manifests a progressive irreversible neurological impairment during infancy and childhood. Hyperhomocysteinemia also showed that it might be involved in pathophysiology of many neuropsychiatric disorders. The late-onset clinical manifestations of these 2 diseases have not been reported elsewhere. We speculated that the late-onset PKU is caused by 2 kinds of metabolic dysfunction synergistically, especially a short period of irregular diet directly caused clinical symptoms. PATIENT CONCERNS: A 21-year old Asian male patient demonstrated subacute leukodystrophy and visual-spatial disorders of late onset in adulthood. DIAGNOSES: Phenylketonuria combined with homocysteinmia, who presented with heterozygous mutations in gene encoding PAH p.G247R (c.739G>C) and p.Y204C (c.611A>G), along with homozygous mutation of gene encoding MTHFR c.677C>T. INTERVENTIONS: The patient was treated with cobalamine (500 MUg/day), vitamin B6 (30 mg/day), folate (5 mg/day) and encouraged to follow a protein-restricted diet. OUTCOMES: Visual disorientation and cognitive function showed improvement. Head MR showed similar resolution with the original lesion. Serum homocysteine and folate analysis were normal with decreased phenylalanine level. LESSONS: This case suggests that neurological involvement of progressive nervous system dysfunction could be caused by more than one kind of inherited metabolic disturbances, and each one can induce or deteriorate the manifestations of another metabolic disorders. PMID- 29465563 TI - Non-Hodgkin lymphoma, diagnostic, and prognostic particularities in children - a series of case reports and a review of the literature (CARE compliant). AB - RATIONALE: Non-Hodgkin lymphoma remains an unpredictable condition in pediatric patients. PATIENT CONCERNS: Our first case describes an 8-year-old boy with a history of iron deficiency anemia, admitted in our clinic for recurrent abdominal pain, weight loss, loss of appetite, diarrheic stools, and fever. The second case also describes an 8-year-old boy admitted for abdominal pain and vomiting. The 3rd case refers to a 4 years and 10 months old boy admitted in our clinic with abdominal pain and loss of appetite, who was initially admitted in the Pediatrics Surgery Clinic with the suspicion of appendicitis. Our 4th patient was a 5-year old boy admitted in our clinic for abdominal pain and intermittent diarrheic stools. DIAGNOSES: In the first case, the laboratory tests showed anemia, thrombocytosis, elevated inflammatory biomarkers, a low level of iron, and hypoproteinemia. The abdominal ultrasound and CT exam revealed an abdominal mass, and the histopathological exam established the diagnosis of diffuse large B-cell lymphoma of the bowel. In the second case, the laboratory tests pointed out anemia, elevated ESR and lactate dehydrogenase level, while both abdominal ultrasound and CT exams showed an abdominal mass. The histopathological exam confirmed the diagnosis of Burkitt lymphoma. Regarding our 3rd case, the laboratory findings revealed leukocytosis, anemia, thrombocytosis, increased inflammatory biomarkers, elevated LDH, and a low level of iron. The abdominal ultrasound and the CT scan revealed an abdominal mass which, according to the histopathological exam, was a Burkitt lymphoma. Due to the cranial CT findings the patient was diagnosed with IV stage Burkitt lymphoma with central nervous system metastases. In our 4th patients we found leukocytosis, anemia, mildly increased inflammatory biomarkers, a high level of LDH, hypoproteinemia, and a low level of serum Ir. Both ultrasound and abdominal CT exams were negative, but the exploratory laparotomy identified an abdominal mass, and according to the histopathological exam the patient was diagnosed with Burkitt lymphoma. INTERVENTIONS: All the patients followed chemotherapy (B-NHL BFM 04 protocol) and supportive treatment. OUTCOMES: The first patient died approximately 4 months after the completion of chemotherapy due to tumor relapse, the second patient died after the first cure of chemotherapy and the fourth patient died at approximately 2 years after the diagnosis. The third patient is recurrence-free after 2 years. LESSONS: Despite the advances in the management, NHL remains a fatal condition in pediatrics. PMID- 29465564 TI - Dental caries and vitamin D3 in children with growth hormone deficiency: A STROBE compliant study. AB - Vitamin D may prevent dental caries. To date, no attempts have been made to examine the correlation between the incidence of caries and the concentrations of vitamin D in children with pituitary growth hormone deficiency.The study observed patients of the Department of Endocrinology and Diabetology of the University Paediatric Hospital of the Medical University of Lublin treated with human recombinant growth hormone for pituitary growth hormone deficiency (GHD). The study was conducted between October 2014 and June 2015. The study group consisted of 121 children and adolescents (6-17 years old), including 56 children from rural areas and 65 children from urban areas. The study group was stratified by area of residence.In our study, the increase in vitamin D3 [25(OH)D] levels reduced the D component by 0.66 per each 10 ng/mL of vitamin D3 concentration. The percentage of children with active caries in rural areas is 91.07% (n = 51), which is significantly higher than the percentage of children with active caries in urban areas (81.54%, n = 53).To date, information regarding the potential possibility of reducing the incidence of dental caries by means of increasing the levels of vitamin D was sidelined by paediatricians and dentists alike. Therefore, this aspect of caries prevention should be highlighted. PMID- 29465565 TI - Peripheral whole blood lncRNA expression analysis in patients with eosinophilic asthma. AB - Long noncoding RNA (lncRNA) plays roles in many diseases including asthma. Several lncRNAs function in the early differentiation of T-helper cells. lncRNA controls gene transcription, protein expression, and epigenetic regulation. Of the 4 asthma phenotypes, eosinophilic asthma (EA) is the most common. However, the lncRNAs associated with eosinophilic asthma have yet to be identified.We designed a study to identify the circulating lncRNA signature in EA samples. We tested whether significant differences in lncRNA expression were observed between blood samples from patients with EA and healthy individuals (control). Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were performed for the lncRNA-mRNA (messenger RNA) co-expression network. lncRNA expression was measured using quantitative real-time PCR (polymerase chain reaction).A total of 41 dysregulated lncRNAs and 762 dysregulated mRNAs (difference >= 2-fold) were found in EA compared to control samples. GO terms and KEGG pathway annotation data revealed that several lncRNAs are significantly associated with EA. KEGG pathway annotation indicated that the pathways most enriched in EA were measles, T cell receptor signaling pathway, peroxisome proliferator activated-receptors (PPAR) signaling pathway, Fc gamma R-mediated phagocytosis, NF (nuclear factor) kappa B signaling pathway, chemokine signaling pathway, and primary immunodeficiency. Using qRT-PCR, lncRNA was confirmed to differ significantly between EA and control samples.The results presented here show that several lncRNAs may take part in the immune regulation of EA. Whether these lncRNAs can be used as biomarkers needs further study. PMID- 29465566 TI - Acupuncture for adults with overactive bladder: A systematic review and meta analysis of randomized controlled trials. AB - BACKGROUND: Overactive bladder is stated as the occurrence of urinary urgency which will cause negative impacts and decrease patients' health-related quality of life. The aim of this systematic review is to assess the efficiency and safety of acupuncture for adults with overactive bladder (OAB) comparing with sham acupuncture, drugs, and acupuncture plus drugs. METHODS: We independently searched 9 databases from beginning to August 15, 2017. Two writers extracted data at the same time independently. Study outcomes were calculated by standardized mean differences (SMD) with 95% confidence intervals (CIs) and mean difference (MD) with 95% CIs. RESULTS: Ten randomized controlled trials (RCTs) with 794 patients were included in this systematic review. The combined results showed that electroacupuncture (EA) may be more effective than sham electroacupuncture (sham EA) in improving the 24-hour nocturia episodes and EA may enhance tolterodine for relieving voiding symptoms and enhancing patients' quality of life. However, more trials with high quality and larger sample sizes will be needed in the future to provide sufficient evidence. Only 15 of 794 OAB patients from the included studies reported mild adverse reactions related to EA, therefore, acupuncture is safe for treating OAB. CONCLUSION: Acupuncture might have effect in decreasing the number of micturition episodes, incontinence episodes, and nocturia episodes. However, the evidence is insufficient to show the effect using acupuncture alone or the additional effect to drugs in treating OAB. PMID- 29465567 TI - Measurement of the nerve root of the lower lumbar region using digital images. AB - The purpose of this study was to evaluate the relationship between the nerve root of lower lumbar and the surrounding structures using three-dimensional computed tomography (3D CT).Twenty-three consecutive patients with thoracolumbar fractures without obvious radiological degeneration were retrospectively studied at the spinal surgery department of the hospital. The parameters of the relationship between the nerve root of the lower lumbar and the surrounding structures were measured using 3D CT in the work station of the picture archiving and communication system.The size of the dorsal root ganglion (DRG) of the L4 was 5.5 +/- 0.4 mm on the right side and 5.8 +/- 0.3 mm on the left side. The size of the DRG of the L5 was 6.1 +/- 0.5 mm on the right side and 5.7 +/- 0.4 mm on the left side. The value of the preganglionic nerve root of the L4 was 11.2 +/- 0.6 mm on the right side and 12.3 +/- 0.8 mm on the left side, and the value of the preganglionic nerve root of the L5 was 15.1 +/- 1.1 mm on the right side and 14.9 +/- 0.9 mm on the left side.Using 3D CT imaging constructed in the picture archiving and communication system is a practical and convenient method for evaluating the relationship between the nerve root and the surrounding structures in the routine clinical work of a spinal surgeon. The data obtained through 3D CT imaging will be helpful for surgeons, allowing them to become more familiar with correlating anatomical knowledge of individual patient. PMID- 29465568 TI - Preliminary evidence: the stress-reducing effect of listening to water sounds depends on somatic complaints: A randomized trial. AB - BACKGROUND: Listening to natural sounds is applied in health contexts in order to induce relaxation. However, it remains unclear whether this effect is equally efficacious in all individuals or whether it depends on interindividual differences. Given that individuals differ in how they are impaired by somatic complaints, we investigated whether somatic complaints moderate the stress reducing effect of listening to water sounds. METHODS: Sixty healthy women (Mage = 25 years) were randomly allocated to 3 different conditions (listening to water sounds, a relaxing piece of music, or no auditory stimulus: n = 20 per condition) for 10 minutes before they were exposed to a standardized psychosocial stress task. Salivary cortisol was assessed before, during, and after the stress task. For binary logistic regression analyses, participants were divided into 2 groups: 1 group with a high salivary cortisol release and 1 group with low cortisol release. The Freiburg Complaints Inventory was used to assess occurrence of somatic complaints. RESULTS: A significant moderating effect of somatic complaints on cortisol secretion was found in the group listening to water sounds (chi(1) = 5.87, P < .015) but not in the other 2 groups, explaining 35.7% of the variance and correctly classifying 78.9% of the cases. CONCLUSION: The stress reducing effect of listening to water sounds appears to depend on the occurrence of somatic complaints. This effect was not found in the music or silence condition. Individuals with somatic complaints may benefit from other, potentially more powerful forms of stress-reducing interventions, that is, combinations of visual and auditory stimuli. TRIAL REGISTRATION: not applicable (pilot study). PMID- 29465569 TI - Three cases of a torn haptic after scleral fixation using a hydrophobic acrylic intraocular lens: Case reports. AB - RATIONALE: We report 3 cases of a torn haptic after successful scleral fixation with a hydrophobic acrylic intraocular lens. PATIENT CONCERNS: Patients complained of decreased visual acuity about 1 week to 1 month after scleral fixation. DIAGNOSES: In all 3 cases, the direction of the damaged haptic correlated with the direction of the pulling force made by the hung suture material. Observation of a cheese-wiring effect on scanning electron microscopy suggested that the haptic was cut by the suture. INTERVENTIONS: Patients underwent re-scleral fixation with caution. OUCTOMES: There was no complication of broken haptic after re-scleral fixation. LESSONS: To avoid unexpected haptic tears, great caution is needed; surgeons should avoid applying excessive pulling force to the intraocular lens when performing scleral fixation using a hydrophobic acrylic intraocular lens.

AB - Categorical syndromes such as schizophrenia may represent complexes of many continuous psychological structural phenotypes along several dimensions of personality development/degeneration. The present study investigated the heritability and familiality of Neuroticism-Extraversion-Openness to experience (NEO) personality dimensions in Korean families with schizophrenic linkage disequilibrium (LD).We have recruited 204 probands (with schizophrenia) with their parents and siblings whenever possible. We have used NEO questionnaires for measuring personality and symptomatic dimensions. Heritabilities of personality dimensions in total 543 family members were estimated using Sequential Oligogenic Linkage Analysis Routines (SOLAR). Personality dimensions in total family members were compared with those in 307 healthy unrelated controls for measuring the familialities using ANOVA analysis.Four of the 5 NEO variables were significantly heritable and were included in the subsequent analyses. The 3 groups (control, unaffected first-degree relative, case) were found to be significantly different and with the expected order of average group scores for all heritable dimensions.Our results show that the aberrations in several personality dimensions could form the complexity of schizophrenic syndrome as a result of genetic-environment coactions or interactions in spite of some limitations (recruited family, phenotyping).

AB - Pyroptosis plays a pivotal role in sepsis and septic shock in animal studies. However, its clinical significance in pathological conditions has not been well elucidated. This study aimed to evaluate the correlation between the percentage of pyroptotic peripheral blood mononuclear cells (PBMCs) and the clinical index and to investigate the relationship between PBMCs pyroptosis and the development of sepsis in trauma patients.This prospective study was conducted from October 2016 to May 2017 in a comprehensive trauma center. Sixty trauma patients and 10 healthy controls were enrolled. Peripheral blood samples were collected from the patients within 24 hours after injury. The percentages of pyroptotic and apoptotic PBMCs were measured using flow cytometry, and plasma levels of cytokines were evaluated using flow cytometric analysis with a human inflammation 13-plex panel.Trauma patients who developed sepsis had higher percentages of pyroptotic and apoptotic PBMCs at admission. Patients who developed sepsis (n = 33) had higher interleukin (IL)-6, IL-18, and monocyte chemotactic protein-1 (MCP 1) concentrations at admission than patients (n = 27) who did not develop sepsis. The percentage of PBMCs pyroptosis was significantly correlated with injury severity score (ISS), acute physiology and chronic health evaluation (APACHE) II score, IL-10, IL-18, and MCP-1 levels in trauma patients. PBMCs pyroptosis is a better biomarker in predicting the development of sepsis after trauma.This study indicates that the percentage of pyroptotic PBMCs increases during the early phase of trauma and that this increase is significantly correlated with the severity and state of inflammation in trauma patients. PBMCs pyroptosis is a potential marker for predicting the development of sepsis after trauma. PMID- 29465572 TI - Therapeutic effect of photodynamic therapy for nonresectable cholangiocarcinoma: Protocol for a meta-analysis and systematic review. AB - BACKGROUND: Cholangiocarcinoma is a malignant neoplasia that originates in the bile ducts. Most patients with cholangiocarcinoma are inoperable at the time of diagnosis. photodynamic therapy (PDT) is a fairly well accepted treatment in clinical practice for nonresectable cholangiocarcinoma (NCC) but lack of quantitatively assessment. Herein, we present a protocol for a systematic review to identify the efficacy of PDT in patients with NCC. METHODS: We will search PUBMED, SpringerLink, Cochrane Library, the Chinese Biomedical database (CBM), WanFang data, China National Knowledge Infrastructure (CNKI) up to December 2017. Studies will be screened by title, abstract, and full text independently and in duplicate. Studies that report PDT in patients with nonresectable cholangiocarcinoma will be eligible for inclusion. Outcome variables will be assessed included survival benefit, health status and quality of life, and adverse events with photodynamic therapy. Assessment of risk of bias and data synthesis will be performed using Revman software. The hazard ratios will be extracted from the survival curves using Tierney Method. Heterogeneity among studies will be assessed using the I statistic. RESULTS: This study will review randomized controlled trials, cohort studies, or retrospective studies and quantitatively assess the efficacy of PDT in patients with NCC for the latest evidence-based recommendation. CONCLUSION: This study will evaluate therapeutic effect of PDT in patients with NCC systematically. We expect that the results from this systematic review for clinical trials will help inform clinical practice in NCC. PMID- 29465573 TI - Synovium as a widespread pathway to the adjacent joint in undifferentiated high grade pleomorphic sarcoma of the tibia: A case report. AB - RATIONALE: Undifferentiated high-grade pleomorphic sarcoma (UPS), originated from bone, is a rare tumor, accounting for 2% to 5% of all primary maligment bone neoplasms. Skip lesion can be found in undifferentiated high-grade pleomorphic sarcoma of bone (UPS-B). However, the direct invasion across the articular synovium to bone has not been reported previously. PATIENT CONCERNS: We report an unusual case of a 65-year-old man complained of a year history of pain, swelling, and limitation of activity in the left knee joint. At the proximal tibia, there was extensive invasion of articular synovium, which provides a direct anatomic pathway for the tumor invasion to the adjacent bone, including patella and femoral condyle. DIAGNOSES: Magnetic resonance imaging was important in defining the marrow involvement and joint invasion, including the thickening articular synovium. Subsequent pathological examination confirmed the diagnosis of UPS. INTERVENTIONS: The patient underwent an extensive resection of the knee joint, except for the patellar. OUTCOMES: After operation, routine chemotherapy was performed. Unfortunately, half a year later, soft tissue swelling of whole thigh was found. Then this patient came our hospital again. Positron emission tomography imaging showed there was recurrence of UPS with lung metastasis. A week later, this patient died. LESSONS: In contrast to frequent infiltration pathway, the articular synovium as a media for this tumor spread is rare. This study adds a better understanding of this direct invasion way to the medical literature. PMID- 29465574 TI - Simultaneous acute Marchiafava-Bignami disease and central pontine myelinolysis: A case report of a challenging diagnosis. AB - RATIONALE: Marchiafava-Bignami disease (MBD) is a rare disease characterized by demyelination of the corpus callosum. It is most commonly seen in patients with chronic alcoholism. The clinical diagnosis of MBD can be difficult due to its nonspecific manifestation. Central pontine myelinolysis (CPM) occurs mostly as a complication of severe and prolonged hyponatremia, especially when corrected too rapidly. However, CPM can be associated with chronic alcoholism and its clinical presentation can be heterogeneous. Because both MBD and CPM can have fatal outcomes, early recognition and treatment can result in a better prognosis. We present a very rare case of simultaneous acute Marchiafava-Bignami disease and central pontine myelinolysis in a patient with chronic alcoholism who was diagnosed unexpectedly using brain magnetic resonance imaging and improved after proper treatment. PATIENT CONCERNS: We presented a case of a 39-year-old patient who visited the hospital with general weakness and an altered neurologic condition after a week of vomiting. DIAGNOSIS: The patient was diagnosed with simultaneous acute Marchiafava-Bignami disease and central pontine myelinolysis using brain magnetic resonance imaging. INTERVENTION: Administration of a high dose of thiamine. OUTCOMES: The neurologic signs improved after a week of thiamine administration. LESSONS: This case suggests that Marchiafava-Bignami disease and central pontine myelinolysis might have a common pathogenesis, and brain magnetic resonance imaging is of crucial importance in chronic alcoholic patients presenting with nonspecific neurological deterioration. The appropriate administration of thiamine may prevent poor outcomes. PMID- 29465575 TI - Impact of vitamin D receptor and binding protein gene polymorphisms in clinical and laboratory data of HCV patients: Cross sectional study. AB - Potential relationship of vitamin D, vitamin D receptor (VDR), and vitamin D binding protein (DBP) have been suggested in the pathophysiology of hepatitis C virus (HCV) infection. The aim of this observational study is to determine vitamin D levels, and VDR and DBP genetic polymorphism according demographic and laboratory data in chronic HCV patients (CHC).A total of 148 CHC patients gave serum samples for testing 25-hydroxyvitamin D (25 (OH)D) level by immunochemiluminometric assay (<20 ng/mL defined as deficient) and donated blood samples to allelic discrimination analysis using TaqMan assays. Analyzed single nucleotide polymorphisms (SNPs) were: VDR-rs7975232 (ApaI) C>A, rs731236 A>G (TaqI), rs1544410 C>T (BsmI), rs10735810 T>C (FokI) and carrier globulin/binding protein (GC)-rs4588 and rs7041 and the haplotype bAt [CCA]. Hepatic fibrosis was assessed using Fib-4 and Forns index.Eighty-two (54.40%) patients demonstrated deficiency of vitamin D and this was associated to AST (P = .019 [CI: 1.003 1.034]), total cholesterol (P = .038 [CI: 1.004-1.164]), fibrosis grade (P < .001 [CI: 0.000-0.844]), and FokI (P = .028) allele T presence. Association was found between VDR polymorphism and fibrosis (BsmI andTaqI), triglycerides (TaqI), and HDL (FokI). DBP polymorphism was associated to HCV genotype (GC rs7041), previous HCV treatment, and GGT (GC rs4588).In conclusion, low frequency of vitamin D deficiency was found, but VDR polymorphisms were frequently associated to fibrosis grade suggesting that they could be used as disease evaluation markers to understand the mechanisms underlying the virus-host interaction. PMID- 29465576 TI - Delayed epidural pseudoaneurysm following cervical laminectomy and instrumentation in a patient with canal stenosis secondary to skeletal fluorosis: A case report. AB - RATIONALE: The typical intraoperative presentation of vertebral artery injury (VAI) usually involves profuse bleeding and requires immediate treatment. However, an occult VAI may occur intraoperatively and result in delayed life threatening epidural pseudoaneurysm several days postoperatively. PATIENT CONCERNS: A 21-year-old man with compressive cervical myelopathy resulting from canal stenosis of skeletal fluorosis underwent decompression of C1 to C7 and instrumentation from C2 to C7. No impressive bleeding event occurred during the operation. On postoperative day 40, progressive quadriplegia developed. DIAGNOSES: Pseudoaneurysm of the VA was established by angiography. INTERVENTIONS: After occlusion of the right VA, the patient underwent hematoma clearing. OUTCOMES: Fortunately, the patient experienced significant recovery of neurologic function after the second surgery. LESSONS: From this case, we realize even in the absence of obvious signs of VAI during a cervical operation, postoperative evaluation should be mandatory for suspected bleeding events occurring at VAI-prone sites during surgery. Moreover, the bone morphological abnormality of skeletal fluorosis was determined to be the most important risk contributing to VAI in this case. The safety limits of bone removal should be determined preoperatively to avoid the effects of bone morphological abnormalities. PMID- 29465577 TI - Nitrite-induced acute kidney injury with secondary hyperparathyroidism: Case report and literature review. AB - RATIONALE: Acute kidney injury (AKI) with hyperparathyroidism caused by nitrite was rare, and renal function and parathyroid hormone (PTH) decreased to normal range after therapy. PATIENT CONCERNS: Acute kidney injury was diagnosed in a 40 year-old male with hyperparathyroidism and cyanosis of his hands and both forearms. DIAGNOSES: The patient ate some recently pickled vegetables, and he experienced nausea, vomiting and diarrhoea without oliguria or anuria; Additionally, his hands and both forearms had a typical blue ash appearance. After admission, the laboratory findings indicated theincreasing serum creatinine (Scr) and parathyroid hormone (PTH). He was diagnosed as acute kidney injury with hyperparathyroidism caused by nitrite. INTERVENTIONS: The patient stopped eating the pickled vegetables and was given rehydration, added calories and other supportive therapy without any glucocorticoids. OUTCOMES: According to his clinical manifestations, laboratory findings and imaging results, the patient was diagnosed with acute kidney injury with secondary hyperparathyroidism. He was given symptomatic supportive care therapy. After one week, the serum creatinine, parathyroid hormone (PTH), hypercalcemia, hyperphosphatemia, proteinuria, and urine red blood cell values decreased to normal range. LESSONS: Nitrite-induced acute kidney injury with secondary hyperparathyroidism was relatively rare. After therapy, the function of the kidney and parathyroid returned to normal. This case suggests that detailed collection of medical history, physical examination and correct symptomatic treatment is very important. PMID- 29465578 TI - Short tandem repeat analysis for confirmation of uterine non-gestational choriocarcinoma in a postmenopausal Taiwanese woman. AB - RATIONALE: Rare uterine choriocarcinoma can be differentiated gestational from nongestational choriocarcinoma by using short tandem repeats (STRs). PATIENT CONCERNS: A 56-year-old Taiwanese woman underwent staging surgery because of suspicion of high-grade endometrial cancer. The pathology-confirmed uterine tumor with syncytiotrophoblasts and decidual change of the endometrium was harvested. DIAGNOSIS: Uterine nongestational choriocarcinoma. INTERVENTIONS: The tumor specimen, the patient's blood, and her husband's blood were drawn for STRs analysis using polymerase chain reaction amplification kit. The genotype of the tumor cells was solely maternal and made the diagnosis of uterine nongestational choriocarcinoma. OUTCOME: Adjuvant chemotherapy with etoposide, methotrexate, actinomycin D, cyclophosphamide, vincristine regimen achieved good response in the patient. The patient is now recurrence-free for 12 months. LESSONS: STRs aid precise classification of rare choriocarcinoma. We encourage using the method to analyze suspicious choriocarcinoma. PMID- 29465579 TI - Efficacy of alemtuzumab and natalizumab in the treatment of different stages of multiple sclerosis patients. AB - BACKGROUND: Multiple sclerosis (MS) is an autoimmune disease, in which the insulating covers of nerve cells in the brain and spinal cord are demyelinated. This study was conducted to compare the efficacy of alemtuzumab and natalizumab in the treatment of different stages of MS patients. METHODS: A total of 585 patients diagnosed with MS and hospitalized were included and analyzed after which they were divided into the primary progressive MS A and B groups, the relapsing-remitting MS (RRMS) C and D groups, and the secondary progressive MS E and F groups. Patients in A, C, and E groups were administered alemtuzumab while those in B, D, and F groups were administered natalizumab for the treatment. The expanded disability status scale (EDSS) scores and the EDSS difference were calculated before and after treatment. The number of head magnetic resonance imaging enhanced lesions in the patients, recurrence time and recurrence rate were measured before and after treatment. RESULTS: The EDSS score of the RRMS group was significantly lower than that of the primary progressive MS group and the secondary progressive MS group. After 12 months of treatment, the EDSS score of RRMS patients treated with natalizumab was significantly lower compared with the patients with alemtuzumab, and the difference before and after treatment was significantly higher than alemtuzumab. The recurrence rate of the RRMS-D group was significantly lower than the RRMS-C group. After 12 months of treatment, compared with the RRMS-C group, a significant reduction was observed in the number of head magnetic resonance imaging enhanced lesions and longer recurrence time in the RRMS-D group. CONCLUSION: The efficacy of natalizumab was better than alemtuzumab in the treatment of patients in the RRMS group, while there was no significant difference among other stages of MS patients, which provided the theoretical basis and clinical guidance for the treatment of different stages of MS. PMID- 29465580 TI - Standard values for gas-perfusion manometry of the esophagus. AB - The manometry with water-perfused or solid-state catheters is the predominant diagnostic procedure to detect motility disorders of the esophagus. Another method is the manometry using gas-perfused catheters. Although the high resolution manometry is the method of first choice, the conventional manometry with helium has some advantages: the simple and hygienically unproblematic use and the absence of any artefacts by the perfusion medium compared with water perfusion, and the considerably lower costs compared with the solid-state catheters. Every method has own normal values because of the specific pressure transmission and the design of the catheter probes. To our knowledge, normal values for gas-perfusion manometry of the esophagus have not yet been published.The esophageal manometry with helium-perfused catheters was performed in 30 healthy volunteers. The main parameters of the esophageal motility and the lower esophageal sphincter were analyzed by liquid and bolus-like swallows and compared with the previous published values in other manometric procedures.The values of the motility in the distal esophagus are consistent; the pressure of the lower esophageal sphincter is generally lower than with other methods. The distal wave amplitude and the propagation velocity are significant higher in the distal esophagus than in the middle. The perfusion medium is well tolerated by the investigated volunteers. PMID- 29465581 TI - Atypical microdeletion in 22q11 deletion syndrome reveals new candidate causative genes: A case report and literature review. AB - RATIONALE: 22q11 deletion syndrome, the most common chromosomal microdeletion disease, is caused by megabase-sized deletions on chromosome 22q11.2. It is characterized by a wide spectrum of congenital anomalies in velopharyngeal and facial, cardiac, genitourinary, vertebroskeletal, respiratory, digestive, and central nervous systems. Phenotype-genotype studies have revealed several causative genes that regulate the development of the third and fourth pharyngeal arches in human. However, the exact pathogenesis of this syndrome remains unknown. Herein, we report a case of 22q11 deletion syndrome with an atypical microdeletion of 125 kb. PATIENT CONCERNS: A 15-year-old Chinese girl presented with symptoms of facial dysmorphia, cardiac defects, velopharyngeal insufficiency, splenomegaly, immunodeficiency, and thrombocytopenia. DIAGNOSES: Microarray analysis revealed a 22q11.23 deletion of 125 kb (chromosome 22: 24276973-24402263), suggesting the diagnosis of 22q11 deletion syndrome. The haploinsufficient genes included GSTT2B, GSTT2, DDTL, DDT, GSTTP1, LOC391322, GSTT1, and GSTTP2. INTERVENTIONS: The patient was administrated glucocorticoids and calcium supplements. OUTCOMES: No epistaxis or petechiae episode occurred during the follow-up; her platelet count ranged between 60 * 10 and 80 * 10/L. LESSONS: Although none of the previous reported causative genes were affected in the patient, her clinical manifestations were typical of 22q11 deletion syndrome, apart from her progressive splenomegaly. This case indicated 8 new candidate pathogenic genes for 22q11 deletion syndrome. Given that the loss of these genes was sufficient to induce 22q11DS defects, whether these genes directly influence the pathogenesis of 22q11DS or through interactions with known hotspot mutations is worthy of research. PMID- 29465582 TI - Successfully treating hand primary tuberculous synovitis by synovectomy combined antituberculous therapy: A case report. AB - RATIONALE: Primary tuberculous infection in hand and wrist is a rare disease. Few articles reported on hand primary tuberculous synovitis. PATIENT CONCERNS: A 68 year-old Chinese male, without history of tuberculosis (TB), had complained of pain and swelling in right palm and little finger for 3 months. Patient came to our hospital on 9th Oct 2016. X-ray just showed soft tissue swelling in little finger. Magnetic resonance imaging (MRI) showed synovitis around flexor tendon of little finger, volar palm, and carpal tunnel. Notably, it also implied nodular images in little finger sizing 5 mm * 11 mm. Laboratory tests revealed C-reactive protein (CRP): 22 mg/L, erythrocyte sedimentation rate (ESR): 49 mm/h, and white blood cells (WBC): 11.8 * 10/L. DIAGNOSES: He was diagnosed with primary hand tuberculous synovitis. INTERVENTIONS: The patient received aspiration biopsy in right palm guided by ultrasound on 13rd Oct and pathological examination indicated Mycobacterium tuberculosis (MTB) infection. We performed radical synovetomy and collected abnormal tissue for pathological examination on 18th Oct. Finally, result showed MTB infection, which was the same with the result of first pathological examination. Then, this patient received antituberculous treatment. OUTCOMES: One year after operation, pain and swelling relieve and no recurrence of the clinical symptoms happened. LESSONS: Primary tuberculous synovitis of hand and wrist is rare, MTB infection should be considered as an infectious agent, especially in developing countries. Radical synovectomy and antituberculous treatment regain a satisfactory outcome. PMID- 29465584 TI - Duplication of the extrahepatic bile duct: A case report and review of the literatures. AB - RATIONALE: Duplication of the extrahepatic bile duct is an extremely rare congenital anomaly of the biliary system. PATIENT CONCERNS: A 44-year-old woman presented with a history of continuous upper abdominal pain and vomiting. DIAGNOSES: Magnetic resonance cholangiopancreatography (MRCP) disclosed diffuse dilatation of the intrahepatic and extrahepatic bile ducts. Endoscopic retrograde cholangiopancreatography (ERCP) showed the presence of two extrahepatic bile ducts with calculus at the distal end of the CBD. INTERVENTIONS: Laparoscopic cholecystectomy (LC) was performed after an ERCP. Choledochoscopy, performed during the operation, showed duplicated common bile duct and the cystic duct was seen opening at the right side of the extrahepatic duct. OUTCOMES: The patient was doing well after 6 months of follow-up. LESSONS: We reported a case of a double common duct with choledocholithiasis and gallstone. This rare anomaly may lead to cholangitis, common bile duct injury during surgery, malignancy occurrence, and should be treated with extreme care. PMID- 29465583 TI - "Living High-Training Low" improved weight loss and glucagon-like peptide-1 level in a 4-week weight loss program in adolescents with obesity: A pilot study. AB - BACKGROUND: "Living High-Training Low" (LHTL) is effective for the improvement of athletic ability; however, little is known about the effect of LHTL on obese individuals. The present study determined whether LHTL would have favorable influence on body composition, rebalance the appetite hormones, and explore the underlying mechanism. METHODS: Adolescents with obesity [body mass index (BMI) >30 kg/m] were randomly assigned to "Living Low-Training Low" (LLTL, n = 19) group that slept in a normobaric normoxia condition and the LHTL (n = 16) group slept in a normobaric hypoxia room (14.7% PO2 ~2700 m). Both groups underwent the same aerobic exercise training program. Morphological, blood lipids, and appetite hormones were measured and assessed. RESULTS: After the intervention, the body composition improved in both groups, whereas reductions in body weight (BW), BMI, and lean body mass increased significantly in the LHTL group (all, P < .05). In the LLTL group, cholecystokinin (CCK) decreased remarkably (P < .05) and CCK changes were positively associated with changes in BW (r = 0.585, P = .011) and BMI (r = 0.587, P = .010). However, in the LHTL group, changes in plasma glucagon like peptide-1 (GLP-1) and interleukin-6 (IL-6) levels, positively correlated with each other (r = 0.708, P = .015) but negatively with BW changes (r = -0.608, P = .027 and r = -0.518, P = .048, respectively). CONCLUSION: The results indicated that LHTL could induce more weight loss safely and efficiently as compared to LLTL and increase the plasma GLP-1 levels that may be mediated by IL 6 to rebalance the appetite. Thus, an efficient method to treat obesity and prevent weight regain by appetite rebalance in hypoxia condition was established. PMID- 29465585 TI - Occurrence of signet-ring cell carcinoma with cholangiocarcinoma 25 years after choledochal cyst excision: A case report. AB - RATIONALE: Choledochal cysts are a risk factor for the development of cholangiocarcinoma. Hence, complete surgical excision is the preferred treatment in most cases. However, cholangiocarcinoma still can develop from the remnant biliary system after surgical excision. Signet-ring cell carcinoma is a rare type of cancer of the biliary system, and the occurrence of signet-ring cell carcinoma after surgical excision of choledochal cysts has not been reported in the English literature to date. PATIENT CONCERNS: We report a case of a 32-year-old woman who presented with a 1-month history of abdominal pain,obstructive jaundice, itching, and fever. The patient had undergone choledochal cyst excision and Roux-en-Y hepatico-jejunostomy 25 years previously and had now developed signet-ring cell carcinoma along with cholangiocarcinoma at the anastomotic site. DIAGNOSES:: signet-ring cell carcinoma along with cholangiocarcinoma. INTERVENTIONS: Interventions included laparotomy with evacuation,blood transfusion,and other adjuvant therapy. OUTCOMES: The patient died five months later. LESSONS: Surgery is the best treatment for CCCs, and the surgeon should try to remove as much as of the bile duct cyst as possible. PMID- 29465586 TI - YiQiFuMai injection for chronic heart failure: Protocol for a systematic review and meta-analysis. AB - BACKGROUND: Chronic heart AQ4 failure (CHF) is the final stage of various heart diseases. YiQiFuMai injection (YQFMI) has been widely applied in the treatment of CHF. However, to our knowledge, there has been no systematic review or meta analysis of randomized controlled trails (RCTs) regarding the effectiveness of this treatment. Here, we provide a protocol to evaluate the efficacy and safety of YQFMI for CHF. METHODS: To evaluate the clinical efficacy of YQFMI in treating CHF, 2 researcher members will independently search the RCTs in the following 8 Chinese and English databases, in which the data collection will be from the time when the respective databases were established to January 2018. The databases will include MEDLINE, EMBASE, Cochrane CENTRAL, CINAHL, the Chinese Biomedical Literature Database, the China National Knowledge Infrastructure, VIP Information and Wanfang Data. The therapeutic effects according to the mortality and the New York Heart Association (NYHA) function classification will be accepted as the primary outcomes. We will use RevMan V.5.3 software as well to compute the data synthesis carefully when a meta-analysis is allowed. RESULTS: This study will provide a high-quality synthesis of current evidence of YQFMI for CHF from several aspects including mortality, NYHA function classification. CONCLUSION: The conclusion of our systematic review will provide evidence to judge whether YQFMI is an effective intervention for CHF.PROSPERO registration number: PROSPERO CRD42017079696. PMID- 29465587 TI - Systemic-pulmonary arteriovenous fistulae with pulmonary hypertension: A case report. AB - BACKGROUND: Arteriovenous (AV) fistulae is an extremely rare disease of vascular malformation that involves fistulae formation between the systemic and pulmonary AV systems. CASE REPRESENTATION: This case report describes a rare systemic pulmonary AV fistulae of congenital origin, accompanied by pulmonary hypertension, as determined by aortic angiography and echocardiography. CONCLUSION: Characteristics, diagnosis, and therapeutic approaches of this rare abnormality are explored. PMID- 29465588 TI - Chart validation of inpatient International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) administrative diagnosis codes for venous thromboembolism (VTE) among intravenous immune globulin (IGIV) users in the Sentinel Distributed Database. AB - The Sentinel Distributed Database (SDD) is a database of patient administrative healthcare records, derived from insurance claims and electronic health records, sponsored by the US Food and Drug Administration for evaluation of medical product outcomes. There is limited information on the validity of diagnosis codes for acute venous thromboembolism (VTE) in the SDD and administrative healthcare data more generally.In this chart validation study, we report on the positive predictive value (PPV) of inpatient administrative diagnosis codes for acute VTE pulmonary embolism (PE) or lower-extremity or site-unspecified deep vein thrombosis (DVT)-within the SDD. As part of an assessment of thromboembolic adverse event risk following treatment with intravenous immune globulin (IGIV), charts were obtained for 75 potential VTE cases, abstracted, and physician adjudicated.VTE status was determined for 62 potential cases. PPVs for lower extremity DVT and/or PE were 90% (95% CI: 73-98%) for principal-position diagnoses, 80% (95% CI: 28-99%) for secondary diagnoses, and 26% (95% CI: 11-46%) for position-unspecified diagnoses (originating from physician claims associated with an inpatient stay). Average symptom onset was 1.5 days prior to hospital admission (range: 19 days prior to 4 days after admission).PPVs for principal and secondary VTE discharge diagnoses were similar to prior study estimates. Position unspecified diagnoses were less likely to represent true acute VTE cases. PMID- 29465589 TI - High-dose tigecycline for the treatment of nosocomial carbapenem-resistant Klebsiella pneumoniae bloodstream infections: A retrospective cohort study. AB - Carbapenem-resistant Klebsiella pneumoniae (CRKP) bloodstream infection (BSI) has become increasingly frequent threat recently, especially in the intensive care unit (ICU). High-dose tigecycline (TGC) regimen is proposed due to the limitation of treatment options. We investigated the efficacy and safety of high-dose TGC combination regimens for treating CRKP BSI. Furthermore, the risk factors for mortality were also determined.This was a single center retrospective cohort study conducted from 2014 to 2016. A total of 40 patients with nosocomial CRKP BSI admitted to the ICU were included; they were classified into two groups according to the treatment regimens with high-dose TGC (HD group) or not (non-HD group). In-hospital mortality rates and microbiologic responses from both groups were reviewed and compared. Besides, the survival and non-survival groups were compared to identify the risk factors of mortality.Twenty-three patients constituted the HD group (high-dosage TGC regimen was administered as 200 mg loading dose followed by 100 mg every 12 h) and 17 patients constituted the non HD group (standard dose TGC therapy as 100 mg loading dose followed by 50 mg every 12 h and other antibiotics). The in-hospital mortality was 52.2% in the HD group and 76.5% in the non-HD group (P = .117). The Kaplan-Meier test showed significantly longer survival times in the HD group (mean: 83 days vs 28 days; P = .027). Microbiological eradication was observed in 13 patients (56.5%) in the HD group and 6 patients (36.3%) in the non-HD group (P = .184). A smaller fraction of patients in the HD group were subjected to vasoactive therapy (52.2% vs 88.2%; P = .016) compared to the non-HD group. There was no significant difference in the manifestation of adverse effects between the two groups. In the multivariate analysis, multiple organ dysfunction syndrome (MODS), vasoactive therapy, and exposure to carbapenems were regarded as the independent predictors of mortality.A therapeutic regimen consisting of a high dose of TGC was associated with significantly longer survival time and numerically lower mortality in CRKP BSI. Adverse events were not increased with the double dose therapy.

AB - The aim of the present study was to investigate the age-related patterns and the relationships between serum levels of tartrate-resistant acid phosphatase-5b (TRACP-5b) or bone-specific alkaline phosphatase (BAP), and the heel stiffness index measured by quantitative ultrasound (QUS) in 429 Japanese men, with special emphasis on 2 age groups (40-59 years and 60 years or over). The heel stiffness index (bone mass) was measured by QUS. Serum samples were collected, and TRACP-5b and BAP levels were measured. The stiffness index was significantly decreased with age. Log (TRACP-5b) was significantly increased with age, but Log (BAP) was stable. Generalized linear models showed that higher levels of Log (TRACP-5b) and Log (BAP) were correlated with a lower stiffness index after adjusting for covariates in men aged 60 years or over, but not in men aged 40 to 59 years. In conclusion, higher rates of bone turnover markers were associated with a lower stiffness index only in elderly men. These results may indicate a different mechanism of low bone mass among different age groups of men. PMID- 29465591 TI - A study on risk factors and diagnostic efficiency of posthepatectomy liver failure in the nonobstructive jaundice. AB - Liver failure remains as the most common complication and cause of death after hepatectomy, and continues to be a challenge for doctors.t test and chi test were used for single factor analysis of data-related variables, then results were introduced into the model to undergo the multiple factors logistic regression analysis. Pearson correlation analysis was performed for related postoperative indexes, and a diagnostic evaluation was performed using the receiver operating characteristic (ROC) of postoperative indexes.Differences in age, body mass index (BMI), portal vein hypertension, bile duct cancer, total bilirubin, alkaline phosphatase (ALP), gamma-glutamyl transpeptidase (GGT), operation time, cumulative portal vein occlusion time, intraoperative blood volume, residual liver volume (RLV)/entire live rvolume, ascites volume at postoperative day (POD)3, supplemental albumin amount at POD3, hospitalization time after operation, and the prothrombin activity (PTA) were statistically significant. Furthermore, there were significant differences in total bilirubin and the supplemental albumin amount at POD3. ROC analysis of the average PTA, albumin amounts, ascites volume at POD3, and their combined diagnosis were performed, which had diagnostic value for postoperative liver failure (area under the curve (AUC): 0.895, AUC: 0.798, AUC: 0.775, and AUC: 0.903).Preoperative total bilirubin level and the supplemental albumin amount at POD3 were independent risk factors. PTA can be used as the index of postoperative liver failure, and the combined diagnosis of the indexes can improve the early prediction of postoperative liver failure. PMID- 29465592 TI - Urinary metalloproteinases and tissue inhibitors of metalloproteinases as potential early biomarkers for renal fibrosis in children with nephrotic syndrome. AB - In chronic glomerulopathies, renal fibrosis (RF) results from extracellular matrix remodeling processes regulated by matrix metalloproteinases (MMP) and tissue inhibitors of metalloproteinases (TIMP). We assessed urinary (u-) and serum (s-) MMP-1, -2, -9, TIMP-1, -2 concentrations and MMP-1, -2, -9/TIMP-1, -2 ratios in children with nephrotic syndrome. Steroid-dependent and steroid resistant nephrotic patients (SDNS-Ps and SRNS-Ps, respectively) were compared with respect to measured parameters. The correlations of measured parameters with magnitude of proteinuria and histopathological diagnosis were determined.The study comprised of 39 children with nephrotic syndrome and 20 healthy controls. Twenty-three patients had SDNS and 16 ones-SRNS. The concentrations MMPs and TIMPs were measured using enzyme-linked immunosorbent assay.In nephrotic patients, higher u-MMP-1, -2, -9/creatinine ratios and u-TIMP-1, -2/creatinine ratios were observed as compared with controls. Nephrotic children were also characterized by lower MMP-1, -2, -9/TIMP-1 ratios. In SRNS-Ps, u-MMP 2/creatinine ratio and u-TIMP-1/creatinine ratio were higher as compared with SDNS-Ps. Magnitude of proteinuria correlated positively with u-MMP-2/creatinine ratio and negatively with u-MMP-2/TIMP-1. In minimal change disease (MCD) patients as compared with those with other glomerulopathies, there was higher u MMP-2/TIMP-1 ratio. No significant differences in s-MMPs, s-TIMPs, and s MMPs/TIMPs ratios between nephrotic patients and controls were observed.Children with nephrotic syndrome are characterized by increased u-fibrotic biomarkers excretions. U-MMP-1, -2, -9 excretions and u-MMP-2/TIMP-1 ratio may become potential early biomarkers for RF. SRNS-Ps, those with heavier proteinuria and other than MCD glomerulopathies, seem to be more susceptible to early RF. PMID- 29465593 TI - Preoperative fluid management in traumatic shock: A retrospective study for identifying optimal therapy of fluid resuscitation for aged patients. AB - Fluid resuscitation was used on aged patients with traumatic shock in their early postoperative recovery. The present study aimed to assess whether different fluid resuscitation strategies had an influence on aged patients with traumatic shock.A total of 219 patients with traumatic shock were recruited retrospectively. Lactated Ringer and hydroxyethyl starch solution were transfused for fluid resuscitation before definite hemorrhagic surgery. Subjects were divided into 3 groups: group A: 72 patients were given aggressive fluid infusion at 20 to 30 mL/min to restore normal mean arterial pressure (MAP) of 65 to 75 mm Hg. Group B: 72 patients were slowly given restrictive hypotensive fluid infusion at 4 to 5 mL/min to maintain MAP of 50 to 65 mm Hg. Group C: 75 patients were given personalized infusion to achieve MAP of 75 to 85 mm Hg. Preoperative infusion volume, preoperative MAP, optimal initial points for surgery, postoperative shock time and mortality rates at 6 and 24 hours after surgery were determined.No significant difference in clinical characteristics was found among the 3 groups. Amount of preoperative infusion was considerably lower in the restrictive group (P < .01, compared with group A). A significant difference in preoperative infusion volume was found between the personalized and other 2 groups (P < .01, compared with groups A and B). Patients in the personalized resuscitation group achieved a higher preoperative MAP (P < .01 compared with Group B; P < .05, compared with group A) and required less prepared time for surgery (P < .01 compared with groups A and B). In addition, a lower mortality rate at 6 and 24 hours after operation was observed in the subjects with personalized therapy (P < .05, compared with group B).Personalized management of fluid resuscitation in traumatized aged patients with appropriate volume and speed of fluid transfusion, suggesting increased survival rate and less prepared time for surgery. PMID- 29465594 TI - Understanding the productive author who published papers in medicine using National Health Insurance Database: A systematic review and meta-analysis. AB - Many researchers used National Health Insurance database to publish medical papers which are often retrospective, population-based, and cohort studies. However, the author's research domain and academic characteristics are still unclear.By searching the PubMed database (Pubmed.com), we used the keyword of [Taiwan] and [National Health Insurance Research Database], then downloaded 2913 articles published from 1995 to 2017. Social network analysis (SNA), Gini coefficient, and Google Maps were applied to gather these data for visualizing: the most productive author; the pattern of coauthor collaboration teams; and the author's research domain denoted by abstract keywords and Pubmed MESH (medical subject heading) terms.Utilizing the 2913 papers from Taiwan's National Health Insurance database, we chose the top 10 research teams shown on Google Maps and analyzed one author (Dr. Kao) who published 149 papers in the database in 2015. In the past 15 years, we found Dr. Kao had 2987 connections with other coauthors from 13 research teams. The cooccurrence abstract keywords with the highest frequency are cohort study and National Health Insurance Research Database. The most coexistent MESH terms are tomography, X-ray computed, and positron-emission tomography. The strength of the author research distinct domain is very low (Gini < 0.40).SNA incorporated with Google Maps and Gini coefficient provides insight into the relationships between entities. The results obtained in this study can be applied for a comprehensive understanding of other productive authors in the field of academics. PMID- 29465595 TI - Discordant CSF/plasma HIV-1 RNA in individuals on virologically suppressive antiretroviral therapy in Western India. AB - Aim of this study was to estimate the prevalence of cerebrospinal fluid (CSF)/Plasma HIV-1 RNA discordance in virologically suppressed individuals presenting with incident neurologic symptoms.In this retrospective cohort study conducted between March 1, 2009, and March 1, 2017, HIV-1 infected adults exposed to atleast 12 months of antiretroviral therapy (ART) and having plasma viral load (VL) <1000 copies/mL (virologically suppressed) were included. Among these, individuals presenting with neurologic symptoms during follow-up were assessed for CSF/Plasma HIV-1 RNA discordance by measuring HIV-1 RNA in collected plasma and CSF samples. CSF/plasma HIV-1 RNA discordance was defined as either detectable CSF HIV-1 RNA (VL > 20 copies/mL) with an undetectable plasma RNA (complete viral suppression, VL <=20 copies/mL) or CSF HIV-1 RNA >= 0.5 log10 higher than plasma RNA when plasma VL was between 20 and 1000 copies/mL (low level viremia, LLV).Out of 1584 virologically suppressed patients, 71 (4.4%) presented with incident neurologic symptoms. Twenty out of 71 (28.2%) patients were diagnosed with CSF/Plasma HIV-1 discordance. Median plasma and CSF VL in patients with discordance was 120 [interquartile range (IQR): <20 to 332.5] and 4250 (IQR: 2550.0- 9615.0) copies/mL, respectively. All 9 individuals in which CSF HIV-1 genotypic resistance testing was done showed mutations that would compromise efficacy of prescribed ART regimen. Prevalence of CSF/plasma HIV-1 RNA discordance was higher among neurologically symptomatic patients with plasma LLV as compared with those with complete viral suppression (70% vs 11.8%, P < .001). The risk of discordance was also greater in patients who received protease inhibitor (PI) containing ART (P < .001) and those on ART regimens with central nervous system (CNS) penetration effectiveness (CPE) value <6 (P = .006).CSF/plasma HIV-1 RNA discordance indicates replication of HIV-1 that has adapted to the CNS or has developed antiretroviral drug resistance. Larger studies should be performed to study incidence of discordance in India. This will help in managing patients presenting with neurologic symptoms on suppressive ART with appropriate neuroeffective therapy. PMID- 29465596 TI - Tianma Gouteng decoction for essential hypertension: Protocol for a systematic review and meta-analysis. AB - BACKGROUND: Essential hypertension is one of the most common chronic diseases, as well as one of the leading risk factors for cardio-cerebrovascular diseases. Tianma Gouteng decoction has been commonly used in clinical practice for patients with essential hypertension. It is important to update the search and evaluation to provide the best available evidence for essential hypertension. Here, we provide a protocol to evaluate the efficacy and safety of Tianma Gouteng decoction (TGD) for essential hypertension. METHODS: Retrieve literature on the TGD treatment for essential hypertension in the databases including PubMed, Cochrane Library, EMBASE, Chinese Biomedical database (CBM), Chinese National Knowledge Infrastructure (CNKI), Wanfang database, and Chinese Science and Technology Periodical database (VIP) on computer. The literature to be collected will be those published from the time when the respective databases were established to January 2018. The therapeutic effects according to the blood pressure (BP) will be accepted as the primary outcomes. We will use RevMan V.5.3 software as well to compute the data synthesis carefully when a meta-analysis is allowed. RESULTS: This study will provide a high-quality synthesis of current evidence of TGD for essential hypertension from several aspects including BP, life quality, heart rate, and adverse events. CONCLUSION: The conclusion of our systematic review will provide evidence to judge whether TGD is an effective intervention for patient with essential hypertension. PROSPERO REGISTRATION NUMBER: PROSPERO CRD 42018082319. PMID- 29465597 TI - Chinese herbal injections for heart failure: A protocol for systematic review and network meta-analyses. AB - BACKGROUND: Chinese herbal injections (CHIs) are commonly used for the treatment of heart failure in China. Due to the variety of CHIs used in clinic, selecting a suitable CHI for patients with heart failure is vital. This study aims to assess and compare the effect of different CHIs for heart failure using network meta analysis (NMA). METHODS: Six electronic databases, including PubMed, the Cochrane Central Register of Controlled Trials, Embase, China National Knowledge Infrastructure, Wanfang, and Chinese Biomedical Literature Database will be search from inception to January 2018. Randomized controlled trial (RCT) comparing CHI with another CHI will be included. The primary outcome will be changes in heart function classification and left ventricular ejection fraction. Risk of bias assessment of the included RCTs will be conducted according to the Cochrane Handbook 5.1.0. A Bayesian NMA will be performed using WinBUGS 14 software and the result figures will be generated using Stata 13 software. GRADE will be used to explore the quality of evidence. RESULTS: The results of this NMA will be published in a peer-reviewed journal. CONCLUSION: Our study will generate evidence of CHIs for patients with heart failure and provide suggestions for Chinese medicine clinical practice or guideline. ETHICS AND DISSEMINATION: Ethics approval and patient consent are not required because this study is an NMA based solely on the published literature. The results of this NMA will be submitted to a peer-reviewed journal. PROTOCOL REGISTRATION NUMBER: PROSPERO CRD 42018086740. PMID- 29465598 TI - Tuina for osteoporosis: A systematic review protocol. AB - BACKGROUND: Osteoporosis is one kind of commonly and frequently occurring global disease accompanying with serious complications. As a branch of the subject of Acupuncture-Tuina, tuina is widely applied for osteoporosis alone or combined with other methods in China and other nations while its effective evidence is not clear. Hence, this systematic review protocol purpose is to evaluate the value of its efficacy and safety for osteoporosis. METHODS: This systematic review and meta-analysis will be performed by means of electronic databases including Cochrane Library, Medline, Cochrane Library, Web of Science, EBASE, Springer, WHO International Clinical Trials Registry Platform (ICTRP), China National Knowledge Infrastructure (CNKI), Wanfang database, Chinese Biomedical Literature Database (CBM), Chinese Scientific Journal Database (VIP) and others with valid search strategy probably. The assessment of bias risk, data synthesis, subgroup analysis, and meta-analyses will be conducted using RevMan V.5.3.5 software. RESULTS: This systematic review will present a high-quality evidence for clinicians and might be the first to evaluate the efficacy and safety of tuina for osteoporosis including alleviation of pain, adverse event, spinal motor function improvement as well as improvement of self-care ability and daily living. CONCLUSION: This protocol will determine whether or not tuina is an effective and safety intervention for osteoporosis. PMID- 29465599 TI - Primary pulmonary lymphoepithelioma-like carcinoma in non-endemic region: A case report and literature review. AB - RATIONALE: Pulmonary lymphoepithelioma-like carcinoma (LELC) is a rare type of lung squamous cell carcinoma. In situ hybridization test for Epstein-Bar virus encoded RNA (EBER) is generally used for distinguishing it from other lung cancers. Although plasma EBV DNA quantification has been widely used as a tumor biomarker in nasopharyngeal carcinoma (NPC), only a limiting number of studies have suggested that plasma EBV DNA quantification may be used as a tumor marker in pulmonary LELC patients. PATIENT CONCERNS: We report two female patients diagnosed as poorly differentiated squamous cell carcinoma, subsequently, their further histological examinations showed that tumor cells were EBER positive and plasma EBV DNA was detectable. DIAGNOSES: Two patients was diagnosed with advanced pulmonary LELC. INTERVENTIONS: The patients were treated with chemotherapy and chemoradiotherapy respectively. OUTCOMES: Both patients responded well to our treatment, in accordance with their decreased EBV DNA level. LESSONS: Pulmonary LELC is a rare type of lung cancer which is sensitive to chemoradiotherapy, especially in late staged patients. PMID- 29465600 TI - A novel endobronchial approach to massive hemoptysis complicating silicone Y stent placement for tracheobronchomalacia: A case report. AB - RATIONALE: Airway stabilization for severe, symptomatic tracheobronchomalacia (TBM) may be accomplished by silicone Y-stent placement. Common complications of the Y-stent include mucus plugging and granulation tissue formation. PATIENT CONCERNS: We describe a rare case of massive hemoptysis originating from a silicone Y-stent placed for TBM. DIAGNOSES: An emergent bronchoscopy showed an actively bleeding, pulsatile vessel at the distal end of the left bronchial limb of the Y-stent. It was felt that the bleeding was caused by, or at least impacted by, the distal left bronchial limb of the Y-stent eroding into the airway wall. INTERVENTIONS: We hypothesized that placement of oxidized regenerated cellulose (ORC) would provide initial hemostasis, and the subsequent placement of a biocompatible surgical sealant would lead to definitive resolution. OUTCOMES: ORC provided sufficient hemostasis and the subsequent synthetic polymer reinforced the tissue for complete cessation of the bleed. LESSONS: The combined use of ORC and a biocompatible surgical sealant provided long-term management for life threatening hemoptysis, and potentially morbid procedures such as embolization or surgery were avoided by advanced endobronchial therapy. PMID- 29465601 TI - Postoperative hemorrhage caused by portal hypertension associated with autoimmune pancreatitis: A case report. AB - RATIONALE: Autoimmune pancreatitis is a form of chronic pancreatitis, characterized by diffused enlargement of the pancreas and irregular narrowing of the main pancreatic duct. The theory that portal hypertension is associated with autoimmune pancreatitis has not been emphasized. In addition, only a few studies report that the gastrointestinal tract hemorrhage caused by portal hypertension is associated with autoimmune pancreatitis. PATIENT CONCERNS: The patient was a 61-year-old male with pancreas occupying lesion detected in a physical examination. Preoperative CT showed portal vein diameter increased significantly (1.6 cm) and the junction of splenic and portal vein was capsuled by lesions and the splenic vein became thin. The Whippie procedure was performed for the correction of the lesion. The pancreatic tissue showed chronic inflammation and lymphocytic infiltration and fibrosis, and abundant IgG4 cells. After the surgery, the patient suffered twice from postoperative hemorrhage (9 and 16 mos). DIAGNOSES: Postoperative hemorrhage, autoimmune pancreatitis. INTERVENTION: Electronic gastroscopy, exploratory laparotomy, and titanium clips were used simultaneously to stop the bleeding. OUTCOMES: The patient recovered well after the surgery. LESSONS: In this study, we present the case of repeated postoperative hemorrhage (9 and 16 mos). We discussed the correlation between postoperative hemorrhage and autoimmune pancreatitis, and the cause of postoperative hemorrhage. PMID- 29465602 TI - Pleomorphic liposarcoma: An analysis of 6 case reports and literature review. AB - RATIONALE: Pleomorphic liposarcoma (PLS), is a rare subtype of liposarcoma, and is considered to be of the highest malignancy grade. PATIENT CONCERNS: We aimed to analyze the clinical features, diagnosis, treatment, and recurrence of the 6 cases of PLS. DIAGNOSES: Six cases with confirmed pathological PLS presented at out hospital from January 2003 to January 2017. The postoperative pathology of 5 cases confirmed PLS, and the other was confirmed as PLS with well-differentiated liposarcoma. INTERVENTIONS: All 6 patients underwent complete tumor resection at the time of the first definite diagnosis, and one of them had underwent 3 cycles of chemotherapy treatment. OUTCOMES: There were 4 cases with local recurrence and surgery was repeated after the first radical excision. One case was not recurrent after 27 months post-operation, and the other was lost. The shortest recurrence time of all of these cases was 4 months, and the longest was 29 months after the first radical surgery. LESSONS: PLS is a rare and high-grade malignancy with high recurrence, poor prognosis, and its treatment is still highly controversial. More studies are required to determine the appropriate treatment and therapeutic strategies to improve the survival rate of patients with PLS, as the disease is associated with frequent relapse. PMID- 29465603 TI - Postoperative delirium after partial laryngectomy in a middle-aged patient: A case report. AB - RATIONAL: Postoperative delirium is a common occurrence in older patients. However, reports of postoperative delirium in middle-aged patients are limited, and the underlying mechanism of delirium in this patient population is not clear. PATIENT CONCERNS: A 45-year-old man who developed postoperative delirium on the second day after partial laryngectomy. Interviews of the surgical team, patient, and patient's spouse revealed that the patient was psychologically stressed, but had not been diagnosed or treated. The patient also suffered impairment in physiological functioning and sleep disturbance after surgery. DIAGNOSIS: Postoperative delirium. INTERVENTIONS: The postoperative delirium was treated with an antipsychotic drug. OUTCOMES: The patient recovered well. LESSONS: Preoperative psychological stress, which is often undiagnosed and untreated, can increase the risk of postoperative delirium in middle-aged patients undergoing laryngectomy. Therefore, screening for psychological stress and implementing strategies to prevent delirium should be considered for patients who undergo laryngectomy, even if they are not in high-risk older age groups. PMID- 29465604 TI - Double laparoscopy assisted cylindrical abdominal-perineal resection for low rectal cancer with 4 cases report. AB - INTRODUCTION: Rectal cancer is a common cancer worldwide. Low rectal cancer exhibits a tendency for recurrence. Surgical resection is an important treatment for rectal cancer. Cylindrical abdominal-perineal resection is suitable for patients with low rectal cancer and has helped improve the prognosis of these patients. However, there are some difficulties during the operation. Especially the perineal area operation cannot be performed under direct vision, which affects the quality of surgical resection. To resolve these constraints, our group designed double laparoscopy assisted cylindrical abdominal-perineal resection for low rectal cancer. CONCLUSION: The procedure effectively solved these problems and reduced the operation time with no increase in surgery complications. PMID- 29465606 TI - Test-Retest Reliability and Concurrent Validity of Athletic Performance Combine Tests in 6-15-Year-Old Male Athletes. AB - Gillen, ZM, Miramonti, AA, McKay, BD, Leutzinger, TJ, and Cramer, JT. Test-retest reliability and concurrent validity of athletic performance combine tests in 6-15 year-old male athletes. J Strength Cond Res 32(10): 2783-2794, 2018-Athletic performance combine tests are used by high school, collegiate, and professional American football programs to evaluate performance; however, limited evidence is available on performance combine test results in youth athletes. The purposes of this study were to report test-retest reliability statistics and evaluate concurrent validity among combine performance tests in 6-15-year-old male athletes. Sixty-nine young male athletes (mean +/- SD; age = 10.9 +/- 2.1 years, height = 154.4 +/- 13.6 cm, body mass = 46.8 +/- 16.0 kg) were divided into 3 age groups: 6-9 years (n = 16), 10-11 years (n = 26), and 12-15 years (n = 27). Participants completed 2 attempts of the vertical jump (VJ), broad jump (BJ), pro agility (PA), L-cone (LC) drill, and 10-, 20-, 40-yd dashes. The results indicated that the older age groups performed better on most performance assessments compared with the 6-9-year group (p <= 0.05). The combine tests demonstrated consistently adequate reliability for all age groups, except for the 10-yd dash, which was deemed unreliable. Evidence of concurrent validity, and possible measurement redundancy were observed in the VJ vs. BJ, PA vs. LC, and 20 vs. 40 yd, but zero- and first-order partial correlations suggested that only the PA and LC were redundant, and the PA may be superior for this age group over the LC. Although the VJ and BJ provide independent performance information regarding lower-body power, questions regarding the redundancy of the 20 vs. 40 yd remain unanswered from a measurement perspective. PMID- 29465605 TI - A false-positive I-131 finding of duodenum diverticulum in thyroid cancer evaluation by SPECT/CT: A case report. AB - RATIONALE: Iodine-131 (I-131) is a sensitive marker for the detection of differentiated thyroid cancer (DTC). I-131 whole-body scintigraphy (WBS) has been used widely in evaluation of DTC patient. However, I-131 WBS exists many false positive uptake of I-131 because radioiodine uptake can also be seen in healthy tissue or in a variety of benign and malignant non-thyroidal tumors. PATIENT CONCERNS: A 44-year-old woman with a papillary thyroid carcinoma for the purpose of ablation therapy after a total thyroidectomy. I-131 WBS showed intensive uptake by thyroid remnant. Meanwhile, a focus of increased activity was seen in right upper abdomen. DISGNOSES, INTERVENTIONS AND OUTCOMES: Based on an I-131 single-photon emission computed tomography/computed tomography (SPECT/CT) fusion imaging combining a Tc-99m pertechnetate dynamic SPECT scan and SPECT/CT fusion imaging with oral administration of iodine contrast agent, a descending duodenum diverticulum was diagnosed. This patient was then treated with conservative treatment, such as diet regulation, rest, appropriate use of antacids and antispasmodic agents, etc. So far, she recovered uneventfully with no any complications. LESSONS: Duodenum diverticulum is a rare false-positive uptake of I-131, it might be a diagnostic challenge when there are many false-positive uptake of I-131 in evaluation of DTC. So it must be significant to be familiar with these physiologic and pathologic variants of I-131 uptake and make further efforts to accurately interpret radioiodine scintigraphy results. PMID- 29465607 TI - The Efficacy of Heart Rate Variability in Tracking Travel and Training Stress in Youth Female Rowers: A Preliminary Study. AB - : (248 words)Heart rate (HR) variability (HRV) is a reliable indicator of cardiac parasympathetic activity and has been used in athletic populations to measure training adaptations. To date, there is limited research showing whether HRV is practical in youth female athletes and rowers during short periods of overload training. PURPOSE: The purpose of this study was to evaluate the practicality of HRV in documenting training responses during a period of overload training in youth female rowers. METHODS: Time domain (standard deviation of RR intervals, SDNN; root mean square of successive differences, RMSSD) and nonlinear (SD1) indices of HRV were recorded during baseline training, daily during the six-day training camp, and one week after the camp in 5 athletes from an elite high school rowing team. Training duration and rate of perceived exertion (RPE) were recorded to document training load. RESULTS: Training load during the camp was 76% above the athlete's normal workload (2258 +/- 459 vs. 1280 +/- 356 a.u.). Using progressive statistics, cardiac vagal activity (RMSSD and SD1) was very likely reduced during each day of the camp when compared with baseline training, though returned to baseline within a week of the training camp. Interestingly, SDNN was reduced throughout the training camp and remained reduced up to a week after the training camp (78% likely, ES=0.32). CONCLUSIONS: These insights add value to HRV's use in youth sport and provides coaches with an easy, cost effective means to monitor the physiological response to training, allowing fine tuning of training, potentially enhancing performance. PMID- 29465608 TI - Muscle Activation Patterns of Lower-Body Musculature Among 3 Traditional Lower Body Exercises in Trained Women. AB - Korak, JA, Paquette, MR, Fuller, DK, Caputo, JL, and Coons, JM. Muscle activation patterns of lower-body musculature among 3 traditional lower-body exercises in trained women. J Strength Cond Res 32(10): 2770-2775, 2018-The deadlift and back and front squats are common multijoint, lower-body resistance exercises that target similar musculature. To our knowledge, muscle activity measured using surface electromyography has never been analyzed among these 3 exercises. Furthermore, most literature examining this topic has included male participants creating a void in the literature for the female population. Knowledge of lower body muscle activation among these 3 exercises can aid coaches, trainers, and therapists for training and rehabilitative purposes. Trained women (n = 13) completed 2 days of testing including a 1-repetition maximum (1RM) estimation, an actual 1RM, and 3 repetitions at 75% 1RM load for the deadlift and back and front squats. Muscle activity of the 3 repetitions of each muscle was averaged and normalized as a percentage to the 1RM lifts for the deadlift and front and back squats. Five separate repeated-measure analysis of variances were performed indicating muscle activity of the gluteus maximus (GM) differed among the 3 exercises (p = 0.01, (Equation is included in full-text article.)= 0.39). Specifically, post hoc analysis indicated greater muscle activity during the front squat (M = 94%, SD = 15%) compared with the deadlift (M = 72%, SD = 16%; p <= 0.05) in the GM. No significant differences were observed among the lifts in the vastus medialis, vastus lateralis, biceps femoris, and rectus femoris. Strength and conditioning specialist and trainers can use these findings by prescribing the front squat to recruit greater motor units of the GM. PMID- 29465609 TI - Novel Myelin Protein Zero Mutation in 3 Generations of Vermonters With Demyelinating Charcot-Marie-Tooth Disease. AB - OBJECTIVES: We report the clinical phenotype in 3 consecutive generations with demyelinating Charcot-Marie-Tooth disease that possess a novel sequence variant of myelin protein zero (MPZ). METHODS: Family members from 3 consecutive generations were interviewed, examined, and studied with electrodiagnostic testing. Commercially available next-generation sequencing was performed for the proband. Single-gene analysis was performed for the remaining family members. RESULTS: All patients demonstrated symmetric distal weakness; symmetric distal sensory loss; and diminished deep tendon reflexes. Electrodiagnostic testing was consistent with primary distal demyelination with secondary axon loss. Genetic testing identified a novel base-pair substitution of MPZ (c.314C>T), resulting in a missense variant (p.Pro105Leu). CONCLUSIONS: The novel MPZ base-pair substitution in this family is associated with inherited distal demyelinating neuropathy and should be reclassified as pathogenic for Charcot-Marie-Tooth. PMID- 29465610 TI - COL6A and LAMA2 Mutation Congenital Muscular Dystrophy: A Clinical and Electrophysiological Study. AB - OBJECTIVES: COL6A and LAMA2 are subtypes of congenital muscular dystrophy. METHODS: Retrospective chart review of clinical findings, spirometry, muscle histology, muscle ultrasound, neuroimaging, and Electromyography (EMG)/Nerve Conduction Study data in genetically confirmed COL6A and LAMA2 subjects. RESULTS: We identified 8 COL6A and 6 LAMA2 subjects: the female-to-male ratio was 1.3:1 and the mean age was 11.9 +/- 3.6 years. Gross motor delays since birth, proximal muscle weakness, and contractures were noted in both groups. Joint hyperlaxity and skin changes (follicular hyperkeratosis and muscle biopsy scar thinning) were unique to COL6A. Severe scoliosis, macrocephaly, and nonambulatory status were common in LAMA2. Increasing age was associated with poor respiratory function in COL6A. There was central "cloud appearance" on rectus femoris muscle ultrasound in COL6A and white matter T2 hyperintensity on brain magnetic resonance imaging in LAMA2. LAMA2 also showed demyelinating polyneuropathy. Neurogenic changes on EMG and muscle histology were noted in 37% and 33% of COL6A cases, respectively. CONCLUSIONS: COL6A has unique skin changes, central cloud appearance on muscle ultrasound. LAMA2 has demyelinating polyneuropathy and white matter changes on brain imaging. The presence of neurogenic changes on EMG and muscle histology in COL6A suggests motor axonal neuropathy. Genetic testing remains the gold standard in confirming COL6A congenital muscular dystrophy. PMID- 29465612 TI - Patient With 2 Hematologic Malignancies Presenting as Neurolymphomatosis. AB - Peripheral nervous system damage from hematologic malignancies is related to neoplastic cells infiltration of peripheral nerves or to monoclonal antibody production cross-reacting with peripheral nerves' antigens. Neurolymphomatosis (NL), a rare manifestation of hematologic malignancies, occurs when malignant cells invade the peripheral nerves leading to various manifestations. Here, we report a case of NL with 2 hematologic malignancies in a 79-year-old woman presenting with lower extremity pain/weakness. Investigation revealed anemia, IgM kappa monoclonal gammopathy, and elevated anti-MAG titer. Electrodiagnostic studies were consistent with mononeuropathy multiplex while imaging suggested malignancy in her ovaries and right S1 nerve root. Bone marrow and ovarian biopsies revealed chronic myelomonocytic leukemia, Waldenstrom macroglobulinemia, and diffuse large B-cell lymphoma. She received standard chemotherapy resulting in radiographic resolution of disease and symptomatic relief. NL can precede the diagnosis of hematologic malignancy but its symptoms are not easily identifiable, whereas management depends on the treatment of the underlying tumor. PMID- 29465611 TI - Mitochondrial DNA Deletions With Low-Level Heteroplasmy in Adult-Onset Myopathy. AB - We report the cases of 2 patients who presented to our Myositis Center with myalgias and elevated creatine kinase levels. Muscle biopsy showed pathological features consistent with mitochondrial myopathy. In both cases, a single large deletion in mitochondrial DNA at low-level heteroplasmy was identified by next generation sequencing in muscle tissue. In 1 case, the deletion was identified in muscle tissue but not blood. In both cases, the deletion was only identified on next-generation sequencing of muscle mitochondrial DNA and missed on array comparative genome hybridization testing. These cases demonstrate that next generation sequencing of mitochondrial DNA in muscle tissue is the most sensitive method of molecular diagnosis for mitochondrial myopathy due to mitochondrial DNA deletions. PMID- 29465613 TI - What is in the Myopathy Literature? AB - This review is focused on recent reports of sporadic inclusion body myositis (sIBM), myopathy in patients with human immunodeficiency virus type 1 (HIV) infection, and necrotizing autoimmune myopathy with antibodies to signal recognition particle. The sIBM articles cover associations with certain genetic polymorphisms, the possible pathogenic role of anti-cytosolic 5'-nucleotidase 1A antibody, and disease-related burden and health care costs. Another article addressed the possible pathogenic role of signal recognition particle antibody in necrotizing myopathy. A series of HIV patients with overlapping features of sIBM and polymyositis are highlighted as is a report of a patient with HIV and late onset rod-body myopathy that may have improved with immunotherapy. PMID- 29465614 TI - Radiation-Induced Painful Neurogenic Hypertrophy Treated With Botulinum Toxin A. AB - Painful neurogenic hypertrophy is a rare complication of radiation therapy. We report a 27-year-old woman with a history of adenoid cystic carcinoma of the submandibular gland presented with painful twitching of her left shoulder. Electrodiagnostic studies were consistent with a diagnosis of radiation-induced spinal accessory nerve hyperactivity. The patient failed conventional medical therapy. She was treated with an injection of botulinum toxin A, and within 1 month experienced significant relief of symptoms. We thus conclude that Botulinum toxin is a therapeutic option for the pain associated with radiation-induced peripheral nerve hyperactivity. PMID- 29465615 TI - Peripheral Vasculitic Neuropathy Associated With Minocycline Use. AB - We describe 2 patients presenting with multiplex mononeuritis, associated with skin manifestation, secondary to minocycline-induced vasculitis. One of the cases is associated neither with lupus nor polyarteritis nodosa. An extensive laboratory workup ruled out any possible underlying immunologic disorder. Electrodiagnostic studies were conducted to show axonal neuropathy in patchy and multifocal distribution consistent with multiplex mononeuritis. This diagnosis was confirmed with nerve biopsy. Withdrawing from the offending medication, minocycline, improved the patients' clinical condition and the quantitative serological measures.

PMID- 29465623 TI - The distinct roles of insular subareas in recognition memory: a stereo electroencephalography study. AB - Previous studies have reported that the insular cortex is involved in recognition memory, but it remains unclear which subarea of the insular cortex serves this function. To address this question, we examined 14 drug-resistant focal epilepsy patients implanted with stereotactic electrodes in the insular cortex. All participants performed a delayed match-to-sample task. Event-related potentials and spectrograms from each insular subarea were analyzed when the participants were exposed to identical (match condition) and different (mismatch condition) stimuli. Each of the insular subareas had a significantly different event-related potential within the investigated interval of recognition memory under both match and mismatch conditions. Moreover, we observed that most of contacts in the left anterior insula had a stronger high-gamma response under the mismatch condition than the match condition, whereas most of contacts in the right insula had a stronger high-gamma response under the match condition than the mismatch condition. Thus, distinct roles for each insular subarea in recognition memory were found in this study. The right insula appears to subserve recognition memory by focusing on processing identical information, whereas the left anterior insula seems to subserve conflict monitoring by focusing on processing different information. PMID- 29465624 TI - Subcortical grey matter structures in multiple sclerosis: what is their role in cognition? AB - The present study aimed to investigate altered grey matter (GM) and functional connectivity (FC) in deep subcortical areas, such as the thalamus and basal ganglia, and their relationship with cognitive impairment (CI) in multiple sclerosis (MS). Thirty-six patients were neuropsychologically assessed, classified as cognitive preserved (CP) and CI, and were compared with 18 healthy controls. GM atrophy and FC were observed in 10 predefined functional areas of the thalamus and in six of basal ganglia. GM atrophy was prominent in the basal ganglia in CI patients compared with CP MS patients. Increased FC was observed between the right caudate and the bilateral orbitofrontal cortex in CI versus CP patients. The discriminant and correlation analyses showed that the enhanced FC observed between the right caudate and the orbitofrontal cortex was closely associated with CI in MS patients. In conclusion, reduced GM volume and enhanced frontobasal ganglia connectivity are related to cognition in MS patients. PMID- 29465625 TI - Spinal bromodomain-containing protein 4 contributes to neuropathic pain induced by HIV glycoprotein 120 with morphine in rats. AB - The symptoms of HIV-sensory neuropathy are dominated by neuropathic pain. Recent data show that repeated use of opiates enhances the chronic pain states in HIV patients. Limited attention has so far been devoted to exploring the exact pathogenesis of HIV painful disorder and opiate abuse in vivo, for which there is no effective treatment. Bromodomain-containing protein 4 (Brd4) is a member of the bromodomain and extraterminal domain protein (BET) family and functions as a chromatin 'reader' that binds acetylated lysines in histones in brain neurons to mediate the transcriptional regulation underlying learning and memory. Here, we established a neuropathic pain model of interaction of intrathecal HIV envelope glycoprotein 120 (gp120) and chronic morphine in rats. The combination of gp120 and morphine (gp120/M, for 5 days) induced persistent mechanical allodynia compared with either gp120 or morphine alone. Mechanical allodynia reached the lowest values at day 10 from gp120/M application, beginning to recover from day 21. In the model, gp120/M induced overexpression of Brd4 mRNA and protein at day 10 using RT-qPCR and western blots, respectively. Immunohistochemical studies showed that Brd4 at day 10 was expressed in the neurons of spinal cord dorsal horn. BET inhibitor I-BET762 dose-dependently increased the mechanical threshold in the gp120/M pain state. The present study provides preclinical evidence for treating HIV neuropathic pain with opioids using the BET inhibitor.

PMID- 29465627 TI - A Social Network Analysis of HIV Treatment Partners and Patient Viral Suppression in Botswana. AB - OBJECTIVE: Many national HIV guidelines recommend that health care providers encourage patients to identify a treatment partner from their social network to support antiretroviral therapy adherence. This study examined associations of patient and treatment partner characteristics with patient viral suppression in Botswana. DESIGN: One hundred thirty-one patients [67 (51.1%) virally suppressed and 64 (48.9%) not suppressed] and their treatment partners were recruited for cross-sectional interviews from one HIV clinic. METHODS: Participants completed surveys assessing social network, sociodemographic, and psychosocial characteristics. Open-ended questions explored treatment partner relationship quality. RESULTS: Multivariate logistic regressions indicated a higher likelihood of viral suppression among patients who reported greater average emotional closeness to their network members [odds ratio (95% confidence interval) = 3.8 (1.3 to 11.5), P = 0.02] and whose treatment partners were spouses/partners [odds ratio (95% confidence interval) = 2.6 (1.0 to 6.7), P = 0.04]. Qualitative analyses indicated that treatment partners of suppressed patients provided both medical and nonmedical support, whereas treatment partners of unsuppressed patients focused mainly on adherence reminders and appointment accompaniment. Treatment partners, especially of unsuppressed patients, requested ongoing training and counseling skills. CONCLUSIONS: Additional research is needed to further explore effective characteristics of treatment partners to inform HIV treatment guidelines. Standard training for treatment partners could include medical-related information and counseling education. PMID- 29465628 TI - Long-Term Clinical and Computed Tomography Angiographic Follow-up After Totally Endoscopic Coronary Artery Bypass Grafting. AB - OBJECTIVE: Totally endoscopic coronary artery bypass grafting was shown to be feasible and safe, with excellent clinical and angiographic mid-term results. Data on long-term outcome are lacking. Therefore, we aimed to investigate the long-term rate of major adverse cardiac and cerebrovascular events and left internal mammary artery patency rate in patients undergoing arrested heart totally endoscopic coronary artery bypass grafting. METHODS: From 2001 to 2012, a total of 208 arrested heart-totally endoscopic coronary artery bypass grafting patients were prospectively included. Mean +/- SD age was 58.8 +/- 9.4 years, and mean +/- SD Society of Thoracic Surgeons score was 0.5 +/- 0.5%. Major adverse cardiac and cerebrovascular events were defined as a composite of death, myocardial infarction, stroke, re-percutaneous coronary intervention, re-coronary artery bypass graft, and target vessel revascularization. Left internal mammary artery patency was assessed using cardiac computed tomography and depicted according to the established Fitzgibbon classification. Mean +/- SD follow-up was 6.9 +/- 2.3 years. RESULTS: At 1, 5, and 10 years, survival rate was 100%, 98.3%, and 95.8%, respectively. The freedom from clinical events at 1, 5, and 10 years were major adverse cardiac and cerebrovascular events (93.5%, 85.9%, and 83.0%), myocardial infarction (99.0%, 97.4%, and 95.9%), target vessel revascularization (96.0%, 94.3%, and 91.7%), re-percutaneous coronary intervention (94.5%, 91.6%, and 84.2%), and re-coronary artery bypass graft (100%, 99.5%, and 99.5%), respectively. Left internal mammary artery patency rate at 1, 5, and 10 years was 100%, 94.9%, and 88.1%, respectively. CONCLUSIONS: Arrested heart-totally endoscopic coronary artery bypass grafting shows excellent clinical long-term results with a left internal mammary artery patency rate comparable with conventional coronary artery bypass graft at 10 years after surgery. PMID- 29465629 TI - Comparison of Automated Titanium Fasteners to Hand-Tied Knots in Open Aortic Valve Replacement. AB - OBJECTIVE: Aortic cross-clamp and cardiopulmonary bypass times are independent predictors of postoperative morbidity and mortality. Reducing ischemic times with automated titanium fasteners may improve surgical outcomes. This study compared operative times and costs of titanium fasteners versus hand-tied knots for prosthesis securement in open aortic valve replacement. METHODS: A randomized control trial was conducted during a 16-month period at a single university medical center. Patients undergoing elective aortic valve replacement were randomized to the titanium fastener (n = 37) or hand-tied groups (n = 36). Knotting, aortic cross-clamp, cardiopulmonary bypass, and total operating room times were recorded. Hospital charges were also calculated for these procedures. RESULTS: Baseline characteristics, concomitant procedures, prosthetic valve size, and sutures were similar between groups. The titanium fastener group had significantly reduced knotting (7.4 vs. 13.0 minutes, P < 0.001), aortic cross clamp (69 vs. 90 minutes, P < 0.05), cardiopulmonary bypass (86 vs. 114 minutes, P < 0.05), and total operating room times (234 vs. 266 minutes, P < 0.05). Intraoperative complications occurred more frequently in the hand-tied group compared with the titanium fastener group. Postoperative complications were similar between groups. Operating room costs were significantly higher in the titanium fastener group (US $10,428 vs. US $9671, P = 0.01). Hospitalization costs did not differ significantly between the titanium fastener and hand-tied group (US $23,987 vs. US $21,068, P = 0.12). CONCLUSIONS: Titanium fastener use was associated with shorter knotting, aortic cross-clamp, cardiopulmonary bypass, and operating room times and fewer intraoperative complications in open aortic valve replacement, without significantly increasing hospitalization cost. PMID- 29465630 TI - Safety and Functionality of a Guidewire Fixator: Clinical Investigation of a New Endovascular Tool. AB - OBJECTIVE: A new endovascular tool, the Liungman Guidewire Fixator, has been developed to simplify endovascular treatment in complex aortic aneurysms. The device has been extensively tested in bench models and animal trials. To verify the safety and functionality demonstrated in the porcine model, the device was tested in ten patients undergoing endovascular aortic repair (EVAR) or fenestrated endovascular aortic repair (f-EVAR) treatment for abdominal aortic aneurysm. METHODS: The Liungman Guidewire Fixator consists of a braided stent like, cylindrical structure with conical ends and a central channel for a 0.035" guidewire. When in use, it is slid along the guidewire and positioned in the target artery, where the Liungman Guidewire Fixator interacts with the arterial wall by anchoring the guidewire to the wall through a radial force. The Liungman Guidewire Fixator allows for uninterrupted blood flow passed the point of fixation. In this study, the Liungman Guidewire Fixator was tested in ten patients undergoing EVAR or f-EVAR treatment for abdominal aortic aneurysm. The device was deployed and retrieved crossover into the hypogastric artery, and the occurrence of thrombotic occlusion, arterial dissection, and vascular rupture or trauma was studied using angiography, as well as device ability to withstand guidewire tension. RESULTS: There were no instances of occlusion, dissection, or vascular trauma detected using angiography. In all cases, deployment and retrieval were successful, and the devices could withstand an applied tension of 3 N. In one instance, retrieval was challenging because of significant tortuosity, which was resolved by a coaxial catheterization. CONCLUSIONS: Deployment was uneventful in all ten patients. Retrieval according to the intended instruction for use was performed in nine of the patients. In one patient, a coaxial catheterization was necessary. All devices withstood a retention force of 3 N. PMID- 29465631 TI - Near-Infrared Cerebral Oximetry to Predict Outcome After Pediatric Cardiac Surgery: A Prospective Observational Study. AB - OBJECTIVES: To assess whether near-infrared cerebral tissue oxygen saturation, measured with the FORESIGHT cerebral oximeter (CAS Medical Systems, Branford, CT) predicts PICU length of stay, duration of invasive mechanical ventilation, and mortality in critically ill children after pediatric cardiac surgery. DESIGN: Single-center prospective, observational study. SETTING: Twelve-bed PICU of a tertiary academic hospital. PATIENTS: Critically ill children and infants with congenital heart disease, younger than 12 years old, admitted to the PICU between October 2012 and November 2015. Children were monitored with the FORESIGHT cerebral oximeter from PICU admission until they were weaned off mechanical ventilation. Clinicians were blinded to cerebral tissue oxygen saturation data. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Primary outcome was the predictive value of the first 24 hours of postoperative cerebral tissue oxygen saturation for duration of PICU stay (median [95% CI], 4 d [3-8 d]) and duration of mechanical ventilation (median [95% CI], 111.3 hr (69.3-190.4 hr]). We calculated predictors on the first 24 hours of cerebral tissue oxygen saturation monitoring. The association of each individual cerebral tissue oxygen saturation predictor and of a combination of predictors were assessed using univariable and multivariable bootstrap analyses, adjusting for age, weight, gender, Pediatric Index of Mortality 2, Risk Adjustment in Congenital Heart Surgery 1, cyanotic heart defect, and time prior to cerebral tissue oxygen saturation monitoring. The most important risk factors associated with worst outcomes were an increased SD of a smoothed cerebral tissue oxygen saturation signal and an elevated cerebral tissue oxygen saturation desaturation score. CONCLUSIONS: Increased SD of a smoothed cerebral tissue oxygen saturation signal and increased depth and duration of desaturation below the 50% saturation threshold were associated with longer PICU and hospital stays and with longer duration of mechanical ventilation after pediatric cardiac surgery.

AB - BACKGROUND: Recent increases in syphilis among men who have sex with men (MSM) are especially concerning, given the biologic and epidemiologic associations between syphilis and HIV infection. We sought to better describe the current epidemiology of primary and secondary (P&S) syphilis and the prevalence of HIV infection among reported P&S syphilis cases by demographic group, including sex of sex partner, in the United States in 2016. METHODS: We reviewed national P&S syphilis case report data from 2016, including available risk factor information such as sex of sex partner and HIV status. Data were extracted from the National Electronic Telecommunications System for Surveillance, the system through which Centers for Disease Control and Prevention receives notifiable sexually transmitted disease data from all 50 states and the District of Columbia. The proportion of cases with HIV coinfection was calculated using cases with known HIV status as the denominator. RESULTS: Of 27,814 P&S syphilis cases reported in 2016, 58.1% were among MSM, 13.9% were among men who have sex with women only, 11.0% were among women, and 16.9% were among men without data on sex of sex partners. Similar patterns were observed across geographic regions, race/ethnicity groups, and most age groups. Overall, 38.5% of reported P&S syphilis cases with known HIV status were coinfected with HIV. The prevalence of HIV coinfection was highest among MSM (47.0%) compared with men who have sex with women only (10.7%) or women (4.1%). Among MSM with P&S syphilis, the prevalence of HIV coinfection was highest among black MSM, ranging from 33.8% among black MSM aged 15 to 19 years to 77.8% among black MSM aged 45 to 49 years. CONCLUSIONS: These data underscore the epidemiologic linkages between syphilis and HIV, particularly among MSM. Primary and secondary syphilis may represent an opportunity to prevent HIV infection among persons who are HIV negative and identify and link to care persons living with HIV infection but not currently engaged in care.

PMID- 29465639 TI - Multi-state Syphilis Outbreak among American Indians, 2013-2015. AB - This article summarizes a multi-state outbreak of heterosexual syphilis, including 134 cases of syphilis in adults and adolescents and at least two cases of congenital syphilis, which occurred on an American Indian reservation in the United States during 2013-2015. In addition to providing salient details about the outbreak, the article seeks to document the case-finding and treatment activities undertaken, their relative success or failure, and the lessons learned from a coordinated, multiagency response. Of 134 adult cases of syphilis, 40% were identified by enhanced, interagency contact tracing and partner services; 26% through symptomatic testing; and 16% through screening of asymptomatic individuals as the result of an electronic medical record (EMR) screening prompt. A smaller proportion of cases were identified by community screening events in high-morbidity communities; high risk venue-based screening events; other screening, including screening upon request; and prenatal screening at first trimester, third trimester, and day-of-delivery. Future heterosexual syphilis outbreak responders should act quickly to coordinate a package of high-yield case finding and treatment activities-potentially including activities that seek to do the following: 1) increase prenatal screening, 2) improve community awareness and symptomatic test-seeking, 3) educate providers and improve general screening for syphilis; 4) implement EMR reminders for providers; 5) screen high-morbidity communities and at high-risk venues; and 6) form novel partnerships to accomplish partner services work when the context does not allow for traditional, DIS-only partner services. PMID- 29465638 TI - Out of the Closet, Into the Clinic: Opportunities for Expanding Men Who Have Sex With Men-Competent Services in China. AB - BACKGROUND: Despite the high human immunodeficiency virus (HIV) burden among men who have sex with men (MSM), there is little research on health services provided to MSM in China and other low- and middle-income countries. Discrimination and inadequate services may discourage MSM from seeking health care services. This study examined essential services provided to MSM and health care discrimination among MSM in China. METHODS: A nationwide cross-sectional online survey was conducted among MSM who saw a physician in the last 24 months in China. The survey included items on sociodemographic information, HIV testing, experiences from the last physician encounter, and history of perceived health care discrimination. We defined MSM-competent physicians as physicians who asked their patient about having sex with other men, asked about anal sex, and either asked about or recommended HIV testing at the most recent visit. RESULTS: Among the 503 participants, 35.0% (176/503) saw an MSM-competent physician. In multivariate analyses, respondents who saw an MSM-competent physician were more likely to be younger (adjusted odds ratio [AOR], 0.87; 95% confidence interval [CI], 0.81 0.94), have a primary care physician (AOR, 3.24; 95% CI, 1.85-5.67), and be living with HIV (AOR, 2.01; 95% CI, 1.13-3.56). 61.2% (308/503) of MSM had ever experienced health care discrimination. CONCLUSIONS: Our data suggest that there is variability in the extent to which physicians are meeting the needs of MSM in China. There is an urgent need to evaluate and expand MSM-competent services in China. PMID- 29465640 TI - Context-Appropriate Interventions to Prevent Syphilis: A Narrative Review. AB - BACKGROUND: The success of an intervention to prevent syphilis will depend on the context and the goal of the intervention. To help programs choose interventions, we reviewed major changes in context and types of interventions that may be effective. METHODS: We reviewed the literature on the changing context of syphilis in the United States and interventions to prevent syphilis, focusing on articles that included evidence of effectiveness. RESULTS: Populations acquiring syphilis are constantly changing. Currently, incidence is very high among men who have sex with men (MSM). Among adults, late disease caused by syphilis has become rare. Congenital syphilis incidence has been low but is increasing, and morbidity and mortality remain high when babies are infected. Congenital syphilis now causes more deaths than syphilis among adults.Routine screening of MSM can identify and treat infections before they progress to disease (secondary prevention). Screening rates are highest when done as part of routine standing orders. Partner notification effectiveness has decreased, partly because many partners are anonymous. Most congenital syphilis can be prevented by screening pregnant women; it has been eliminated in areas where intense primary prevention efforts eliminated syphilis among women. CONCLUSIONS: So far, no program has stopped the increasing rates of infection among MSM, but secondary prevention efforts have prevented most disability. Congenital syphilis is increasing, and can be decreased by screening pregnant women and stopped by intensive efforts to prevent infection among women. PMID- 29465641 TI - Relative Impact of Different Strategies for Allocating Federal Funds for Syphilis Prevention. AB - BACKGROUND: Improvements in resource allocation can increase the benefits of federally funded sexually transmitted disease (STD) prevention activities. The purpose of this study was to illustrate how different strategies for allocating federal funds to subnational districts for syphilis prevention might affect the incidence of syphilis at the national level. METHODS: We modeled syphilis rates by district and year using an equation based on a previous analysis of state level syphilis elimination funding and syphilis case rates from 1998 to 2005 in the United States. We used the model to illustrate the potential impact of 3 different strategies for allocating supplemental federal funds to subnational districts to support syphilis prevention activities a hypothetical country with 18 subnational districts. The 3 strategies were based on each district's (1) population size, (2) syphilis incidence rate, or (3) number of syphilis cases. The hypothetical country was similar to the United States in overall population and syphilis burden. RESULTS: Without the supplemental federal funds, there would be an estimated 48,600 incident infections annually in the hypothetical country. With the supplemental federal funds, the annual number of infections would be reduced to 27,800 with a population-based allocation of funding to each district, 26,700 with a rate-based allocation, and 24,400 with a case-based allocation of funding. CONCLUSIONS: Allocating federal STD prevention funds to districts based on burden of disease can be an efficient strategy, although this efficiency may be reduced or eliminated when high-burden districts have less ability to provide adequate STD prevention services than lower-burden districts. PMID- 29465642 TI - Spontaneous Clearance of Pharyngeal Gonococcal Infections: A Retrospective Study in Patients of the Sexually Transmitted Infections Clinic; Amsterdam, the Netherlands; 2012 to 2015. AB - INTRODUCTION: Pharyngeal Neisseria gonorrhoeae infections are mostly asymptomatic, yet sustain ongoing gonococcal transmission. We assessed the proportion of pharyngeal gonorrhea that spontaneously clears and identified determinants of clearance. METHODS: At the sexually transmitted infections clinic Amsterdam, at-risk women and men who have sex with men were routinely screened for pharyngeal N. gonorrhoeae using an RNA-based nucleic acid amplification test (NAAT; Aptima Combo 2).We retrospectively examined medical records of pharyngeal gonorrhea patients (January 2012-August 2015). We included patients who returned for antibiotic treatment and had a new sample taken for NAAT before treatment. Spontaneous clearance was defined as a negative NAAT result at the follow-up visit. RESULTS: During the study period, 1266 cases with a pharyngeal gonorrhea were not treated at the first consultation and returned for a follow-up visit. Median (interquartile range) time between the first consultation and follow-up was 10 (7-14) days. Spontaneous clearance was found in 139 cases (11.0%) and was associated with age at least 45 years (vs. 16-24 years; adjusted odds ratio, 2.02 [95% confidence interval, 1.09-3.75]) and with time from the first consultation to follow-up (adjusted odds ratio, 1.08 [1.06-1.10], per extra day). CONCLUSIONS: Eleven percent of pharyngeal gonorrhea cases cleared spontaneously. Spontaneous clearance of pharyngeal gonorrhea was more often seen among older patients. PMID- 29465643 TI - Human Immunodeficiency Virus Partner Notification Services Among a Representative Sample of Young Black Men Who Have Sex With Men Demonstrates Limited Service Offering and Potential Benefits of Clinic Involvement. AB - BACKGROUND: Partner notification (PN) is commonly offered to persons recently diagnosed with human immunodeficiency virus (HIV) to improve linkage to care and prevent onward transmission. Yet, much remains unknown about the factors associated with successful PN participation in populations at highest risk. METHODS: Data were collected during the first 2 waves (2013-2015) of "uConnect," a population-based cohort study of young black men who have sex with men in Chicago (N = 618). Participants completed a biobehavioral survey and were tested for HIV. Among HIV-infected participants (N = 187), weighted logistic regression models examined the relationship between participant characteristics and being offered PN and providing partner names. RESULTS: 30.3% (n = 187) of the sample was HIV-positive, of which 71.7% (n = 134) were offered PN, including: 8.2% (n = 11) by the city health department; 51.5% (n = 69) by health care providers; and 40.3% (n = 54) by both. Being offered PN was significantly associated with criminal justice involvement history (adjusted odds ratio [aOR], 2.49; 95% confidence interval [CI], 1.38-4.49), volatile nitrates usage (aOR, 2.88; 95% CI, 1.20-6.94), and recent conversations with HIV outreach workers (aOR, 2.68; 95% CI, 1.25-5.77). Providing partner names was significantly associated with intermittent (aOR, 7.26; 95% CI, 1.75-30.07) and heavy (aOR, 11.47; 95% CI, 2.57 51.22) marijuana use, and being offered PN by both the city health department and health care provider (aOR, 8.36; 95% CI, 2.73-25.62). CONCLUSIONS: A substantial proportion of HIV-diagnosed individuals were never offered PN. Being offered PN by multiple sources is associated with participation, and improved collaboration within health systems may improve participation rates. PMID- 29465644 TI - State laws related to billing third parties for healthcare services at public STD clinics in the United States. AB - BACKGROUND: Health departments (HDs) cite state laws as barriers to billing third parties for sexually transmitted disease (STD) services, but the association between legal/policy barriers and third party HD billing has not been examined. This study investigates the relationship between laws that may limit HDs' ability to bill, clinic perceptions of billing barriers, and billing practices. METHODS: Two surveys (1) clinic managers [N=246], 2) STD program managers [N=63]) conducted via a multi-regional needs assessment of federally funded HD clinics' capacity to bill for STD services, billing/reimbursement practices, and perceived barriers were combined with an analysis of state laws regarding third party billing for STD services. Statistical analyses examined relationships between laws that may limit HDs' ability to bill, clinic perceptions, and billing practices. RESULTS: Clinic managers reported clinics were less likely to bill Medicaid and other third parties in jurisdictions with a state law limiting their ability to bill compared to respondents who billed neither or one payer (OR=0.31, CI=0.10,0.97) and cited practical concerns as a primary barrier to billing (OR=2.83 CI=1.50,5.37). STD program managers' reports that staff believed STD services should be free (OR=0.34, CI=0.13, 0.90) was associated with not billing (not sure versus no resistance to billing); confidentiality concerns was not a reported barrier to billing among either sample. CONCLUSIONS: Practical concerns and clinic staff beliefs that STD services should be free emerged as possible barriers to billing, and laws less so. Attempts to initiate HD billing for STD services may benefit from staff education as well as addressing perceived legal barriers and staff concerns. PMID- 29465645 TI - Assessing STD Partner Services in State and Local Health Departments.

PMID- 29465646 TI - New Human Immunodeficiency Virus Diagnoses Among Men Who Have Sex With Men Attending Sexually Transmitted Disease Clinics, STD Surveillance Network, January 2010 to June 2013. AB - : To estimate new human immunodeficiency virus (HIV) diagnosis rates among HIV negative men who have sex with men (MSM) who are repeatedly tested for HIV in sexually transmitted disease (STD) clinics and assess the impact of demographic and disease-specific characteristics that are associated with higher HIV diagnosis rates. STUDY DESIGN: Retrospective analysis using 2010 to 2013 data from the STD Surveillance Network (SSuN), a sentinel surveillance system comprised of health departments in 12 cities conducting sentinel surveillance in 40 STD clinics. We analyzed data from all MSM repeatedly (>=2 times) tested for HIV, with an initial negative HIV test required for staggered cohort entry. Follow-up time was accrued from the date of the first negative HIV test to the most recent negative test or the first positive HIV test. The STD diagnoses during the follow-up period were reviewed. We estimated HIV diagnoses rates (number of HIV diagnoses/total number of person-years [PY] at risk) by demographic and clinical characteristics with 95% confidence intervals (CI) using an inverse variance weighted random effects model, adjusting for heterogeneity between SSuN jurisdictions. RESULTS: Overall, 640 HIV diagnoses occurred among 14,824 individuals and 20,951.6 PY of observation, for an adjusted incidence of HIV diagnosis of 3.0 per 100 PY (95% CI, 2.6-3.4). Rates varied across race/ethnicity groups with the highest rate among Blacks (4.7/100 PY; 95% CI, 4.1 5.3) followed by Hispanics, whites, and persons of other races/ethnicities. Men who have sex with men having a diagnosis of primary or secondary (P&S) syphilis on or after the first negative HIV test had a higher new HIV diagnosis rate (7.2/100 PY; 95% CI, 5.8-9.0) compared with MSM who did not have a P&S syphilis diagnosis (2.8/100 PY; 95% CI, 2.6-3.1). Men who have sex with men who tested positive for rectal gonorrhea (6.3/100 PY; 95% CI, 5.7-6.9) or rectal chlamydia (5.6/100 PY; 95% CI, 4.6-6.6) had higher rates of new HIV diagnosis when compared to those with negative test results. CONCLUSIONS: Men who have sex with men attending SSuN STD clinics have high rates of new HIV diagnoses, particularly those with a previous diagnosis of P&S syphilis, rectal chlamydia, and/or gonorrhea. Sexually transmitted disease clinics continue to be important clinical setting for diagnosing HIV among MSM populations. PMID- 29465647 TI - Sexually Transmitted Infection Positivity Rate and Treatment Uptake Among Female and Male Sexual Assault Victims Attending The Amsterdam STI Clinic Between 2005 and 2016. AB - BACKGROUND: Victims could become infected with sexually transmitted infections (STIs) during a sexual assault. Several guidelines recommend presumptive antimicrobial therapy for sexual assault victims (SAVs). We assessed the STI positivity rate and treatment uptake of female and male SAVs at the Amsterdam STI clinic. METHODS: Sexual assault victims answered assault-related questions and were tested for bacterial STI (chlamydia, gonorrhea, and syphilis), hepatitis B, and HIV during their initial visits. Sexual assault victim characteristics were compared with non-SAV clients. Backward multivariable logistic regression analysis was conducted to assess whether being an SAV was associated with a bacterial STI. The proportion of those returning for treatment was calculated. RESULTS: From January 2005 to September 2016, 1066 (0.6%) of 168,915 and 135 (0.07%) of 196,184 consultations involved female and male SAVs, respectively. Among female SAVs, the STI positivity rate was 11.2% versus 11.6% among non-SAVs (P = 0.65). Among male SAVs, the STI positivity rate was 12.6% versus 17.7% among non-SAVs (P = 0.12). In multivariable analysis, female SAVs did not have increased odds for an STI (odds ratio 0.94; 95% confidence interval, 0.77-1.13), and male SAVs had significantly lower odds for an STI (odds ratio, 0.60; 95% confidence interval, 0.36-0.98). Of SAVs requiring treatment, 89.0% (female) and 92.0% (male) returned. CONCLUSIONS: The STI positivity rate among female SAVs was comparable with female non-SAVs, but male SAVs had lower odds for having a bacterial STI than did male non-SAVs, when adjusting for confounders. The return rate of SAV for treatment was high and therefore does not support the recommendations for presumptive therapy. PMID- 29465648 TI - Associations Between Anorectal Chlamydia and Oroanal Sex or Saliva Use as a Lubricant for Anal Sex: A Cross-sectional Survey. AB - BACKGROUND: Receptive condomless anal sex is a known risk factor for anorectal chlamydia, but it remains unclear whether oroanal sex practices also contribute. We aimed to determine whether oroanal sex ("rimming"), fingering, or the use of saliva as anal lubricant are risk factors for anorectal chlamydia among men who have sex with men (MSM). METHODS: This cross-sectional study was conducted at Melbourne Sexual Health Centre from July 2014 to June 2015. Routinely collected computer-assisted self-interview data included demographics, number of sexual partners, and condom use. We added questions on receptive rimming, receptive fingering or penis "dipping," and the use of a partner's saliva as anal lubricant. RESULTS: A total of 1691 MSM completed the questionnaire and tested for anorectal chlamydia. In univariable analyses, anorectal chlamydia was associated with using a partner's saliva as lubricant (odds ratio [OR] 1.97, 95% confidence interval [CI] 1.26-3.09), receptive rimming (OR 1.59; 95% CI 1.04 2.45), and receptive fingering or dipping (OR 1.90; 95% CI 1.06-3.43). In multivariable analysis, anorectal chlamydia was not associated with these sexual practices, after adjusting for number of sexual partners, HIV status, known contact with chlamydia, and condom use. However, collinearity between sexual practices likely obscured associations with anorectal chlamydia, and further analyses suggested weak associations between these sexual practices and anorectal chlamydia. CONCLUSIONS: The use of a partner's saliva during receptive anal sex practices such as rimming, fingering, or penis dipping were weak risk factor for anorectal chlamydia in MSM. This contrasts with our previously reported findings that the use of saliva as anal lubricant is more strongly associated with anorectal gonorrhea. PMID- 29465649 TI - Mycoplasma genitalium Infection in Kenyan and US Women. AB - BACKGROUND: Little is known about the natural history of Mycoplasma genitalium (MG) infection in women. We retrospectively tested archived vaginal fluid samples to assess MG prevalence, incidence, persistence, recurrence and antimicrobial resistance markers among women participating in the Preventing Vaginal Infections trial, a randomized trial of monthly presumptive treatment to reduce vaginal infections. METHODS: High-risk, nonpregnant, HIV-negative women aged 18 to 45 years from Kenya and the United States were randomized to receive metronidazole 750 mg + miconazole 200 mg intravaginal suppositories or placebo for 5 consecutive nights each month for 12 months. Clinician-collected swabs containing cervicovaginal fluid were tested for MG using Hologic nucleic acid amplification testing at enrollment and every other month thereafter. Specimens that were MG+ underwent additional testing for macrolide resistance-mediating mutations by DNA sequencing. RESULTS: Of 234 women enrolled, 221 had available specimens and 25 (11.3%) had MG at enrollment. Among 196 women without MG at enrollment, there were 52 incident MG infections (incidence, 33.4 per 100 person-years). Smoking was independently associated with incident MG infection (adjusted hazard ratio, 3.02; 95% confidence interval, 1.32-6.93), and age less than 25 years trended toward an association (adjusted hazard ratio, 1.70; 95% confidence interval, 0.95 3.06). Median time to clearance of incident MG infections was 1.5 months (interquartile range, 1.4-3.0 months). Of the 120 MG+ specimens, 16 specimens from 15 different women were macrolide resistance-mediating mutation positive (13.3%), with no difference by country. CONCLUSIONS: M. genitalium infection is common among sexually active women in Kenya and the Southern United States. Given associations between MG and adverse reproductive health outcomes, this high burden of MG in reproductive-aged women could contribute to substantial morbidity. PMID- 29465650 TI - Chlamydia Prevalence Trends Among Women and Men Entering the National Job Training Program From 1990 Through 2012. AB - BACKGROUND: Evaluating chlamydia prevalence trends from sentinel surveillance is important for understanding population disease burden over time. However, prevalence trend estimates from surveillance data may be misleading if they do not account for changes in risk profiles of individuals who are screened (case mix) and changing performance of the screening tests used. METHODS: We analyzed chlamydia screening data from a sentinel surveillance population of 389,555 young women (1990-2012) and 303,699 young men (2003-2012) entering the US National Job Training Program. This period follows the introduction of national chlamydia screening programs designed to prevent transmission and reduce population disease burden. After ruling out bias due to case mix, we used an expectation maximization-based maximum likelihood approach to account for measurement error from changing screening tests, and generated minimally biased long-term chlamydia prevalence trend estimates among youth and young adults in this sentinel surveillance population. RESULTS: Adjusted chlamydia prevalence among women was high throughout the study period, but fell from 20% in 1990 to 12% in 2003, and remained between 12% and 14% through 2012. Adjusted prevalence among men was steady throughout the study period at approximately 7%. For both women and men, adjusted prevalence was highest among Black and American Indian youth and young adults, and in the Southern and Midwestern regions of the United States throughout the study period. CONCLUSIONS: Our minimally biased trend estimates provide support for an initial decrease in chlamydia prevalence among women soon after the introduction of national chlamydia screening programs. Constant chlamydia prevalence in more recent years suggests that screening may not be sufficient to further reduce chlamydia prevalence among high-risk youth and young adults. PMID- 29465651 TI - The Epidemiology of Syphilis in New York City: Historic Trends and the Current Outbreak Among Men Who Have Sex With Men, 2016. AB - BACKGROUND: Male primary and secondary (P&S) and early latent syphilis cases have increased markedly in New York City (NYC) after a historic nadir in 1998. The majority of cases are among men who have sex with men (MSM). We describe the epidemiology of syphilis among NYC males to provide a model of how 1 jurisdiction collects, analyzes, interprets, uses, and disseminates local data to guide programmatic activities directed at syphilis control. METHODS: We analyzed trends in reported infectious syphilis cases using routinely collected surveillance and case investigation data. Human immunodeficiency virus (HIV) coinfection status was ascertained by routine deterministic match between sexually transmitted infection and HIV surveillance registries, and self-report. We mapped diagnosing facilities to display the relative contribution of different public/private facilities. Characteristics of male syphilis cases diagnosed in public sexual health (SH) clinics were compared to those diagnosed elsewhere. RESULTS: During 2012 to 2016, male P&S syphilis case rates increased 81%, from 24.8 to 44.8/100,000 (1832 cases in 2016); the highest rates were among black non Hispanic men. Overall, 87.6% (902/1030) of interviewed men in 2016 disclosed 1 or more male partner. The HIV coinfection rates are high among MSM with P&S syphilis (43.4%; 394/907 in 2016), but appear to be decreasing (from 54.1% in 2012). Maps highlight SH clinics' contribution to diagnosing P&S syphilis cases among men of color. HIV coinfection rates were lower among men with P&S syphilis diagnosed in SH clinics than among those diagnosed elsewhere (34%, SH clinics vs 49%; other settings, P < 0.0001). CONCLUSIONS: Syphilis infections continue to increase among MSM in NYC. Novel interventions responsive to the drivers of the current outbreak are needed. PMID- 29465652 TI - Whose Responsibility Is It? Beliefs About Preventing HIV Transmission Among Men Who Have Sex With Men. AB - HIV-negative and HIV-positive men believed that they both are responsible for preventing HIV. Responsibility beliefs, however, did not always correspond with discussing HIV status or refraining from serodiscordant condomless anal sex. Discrepancies between individuals' HIV prevention responsibility beliefs and their sexual risk behaviors merit further examination, particularly in the preexposure prophylaxis era. PMID- 29465653 TI - Clinical Characteristics of Anorectal Mycoplasma genitalium Infection and Microbial Cure in Men Who Have Sex With Men. AB - BACKGROUND: We report clinical characteristics of proctitis caused solely by Mycoplasma genitalium (MG) compared with chlamydia and gonococcus. We determined the proportions cured with first-line (azithromycin) and second-line antimicrobials (moxifloxacin, pristinamycin). METHODS: A total of 166 patients attending Melbourne Sexual Health Centre from 2012 to 2016 with symptoms of proctitis were tested for MG, Chlamydia trachomatis, and Neisseria gonorrhoeae. Demographic characteristics, sexual behaviors, clinical symptoms, and signs were recorded. Multinomial multivariable logistic regression was used to test for significant differences in symptoms and signs for the pathogens detected. RESULTS: Seventeen percent of men had MG (95% confidence interval, 12-24), 21% had chlamydia (15-27), and 40% had gonococcal monoinfection (32-48), whereas 22% had MG coinfection (16-29). Relative to men with MG monoinfection, those with chlamydial monoinfection reported more anal pain (adjusted prevalence odds ratio (aPOR), 4.68 [1.41-14.19]), whereas men with gonococcal monoinfection reported more anal pain (aPOR, 6.75 [2.21-20.55]) and tenesmus (aPOR, 15.44 [1.62 146.90]), but less anal itch (aPOR, 0.32 [0.11-0.93]). The microbiological cure for MG using azithromycin was low at 35% (22-50), whereas moxifloxacin subsequently cured 92% (64-100) and pristinamycin cured 79% (54-94) of infections. CONCLUSIONS: M. genitalium was almost as common as chlamydia in men presenting to a sexual health center with symptoms of proctitis. Men with anorectal MG monoinfection were less likely to have symptoms and signs compared with those with chlamydia or gonococcus monoinfection. Cure for men with symptomatic anorectal MG by azithromycin was low. We suggest routine testing for MG in cases of proctitis, with test of cure after treatment being essential. PMID- 29465654 TI - HIV Co-infection among Persons Diagnosed with Sexually Transmitted Diseases, San Francisco, 2007-2014. AB - BACKGROUND: Early syphilis, gonorrhea, and chlamydia but not HIV infections have increased in San Francisco, primarily among men. METHODS: We linked records of persons reported with early syphilis, gonorrhea, and chlamydia to records of persons reported with HIV to measure the proportion and characteristics of San Francisco residents with HIV-STD co-infection between 2007 and 2014. We measured trends in HIV co-infection separately for men and women for each STD. RESULTS: From 2007 through 2014, 5,745 early syphilis, 18,037 gonorrhea, and 37,224 chlamydia diagnoses were reported, 66%, 28%, and 15%, respectively, were among persons co-infected with HIV. Men accounted for the majority of persons with early syphilis, gonorrhea, and chlamydia HIV co-infection. For early syphilis and HIV co-infection, among MSM, Latinos were more likely and Asian/Pacific Islanders were less likely to have HIV co-infection compared to Whites. Older age at diagnosis and prior history of a STD were both also significantly associated with early syphilis and HIV co-infection. Transgender persons, older ages, Latino MSM compared to White MSM and those with a prior history of STD were more likely to have HIV co-infection whereas Asian/Pacific Islander MSM were less likely to have HIV co-infection for both gonorrhea and chlamydia. CONCLUSIONS: Our findings highlight the high burden of HIV-STD co-infection in San Francisco. To maintain the current declines in HIV incidence and turn the curve in rising STD incidence, there is an urgent need for collaborative HIV and STD prevention and control efforts. PMID- 29465655 TI - Defining the Urethritis Syndrome in Men Using Patient Reported Symptoms. AB - To evaluate self-reported symptoms to guide urethritis diagnosis, symptomatic men being evaluated for urethritis were asked about 7 symptoms captured during history taking. Discharge and dysuria were significantly associated with urethritis and, when combined with genital irritation and itching, identified 95% of urethritis cases; odor and urinary frequency performed poorly. PMID- 29465656 TI - Herpes Simplex Virus Type 2 Seroprevalence Among Different National Populations of Middle East and North African Men. AB - BACKGROUND: There are limited data on herpes simplex virus type 2 (HSV-2) seroprevalence in the Middle East and North Africa (MENA). We examined country- and age-specific HSV-2 seroprevalence among select MENA populations residing in Qatar. METHODS: Sera were collected from male blood donors attending Hamad Medical Corporation between June 2013 and June 2016. Specimens were screened for anti-HSV-2 IgG antibodies following a 2-test algorithm: HerpeSelect 2 ELISA was used to identify HSV-2-positive specimens, and Euroline-WB was used to confirm positive and equivocal specimens for final HSV-2 status. Trends and associations with HSV-2 seropositivity were assessed. RESULTS: Of the 2077 tested sera, 61 were found and confirmed positive. The proportion of those confirmed positive increased steadily with HerpeSelect 2 ELISA index value, ranging from 16.3% for index values of 1.101 to 1.999 to 92.9% for index values of 4 or greater. Nationality-specific seroprevalence was 6.0% (95% confidence interval [CI], 4.1% 8.8%) in Qataris, 5.3% (95% CI, 2.5%-11.1%) in Iranians, 4.2% (95% CI, 1.8%-9.5%) in Lebanese, 3.1% (95% CI, 1.2%-7.7%) in Sudanese, 3.0% (95% CI, 1.4%-6.4%) in Palestinians, 2.2% (95% CI, 1.1%-4.3%) in Egyptians, 2.0% (95% CI, 1.0%-5.0%) in Syrians, 1.0% (95% CI, 0.3%-3.6%) in Jordanians, 0.7% (95% CI, 0.1%-3.7%) in Yemenis, and 0.5% (95% CI, 0.1%-2.8%) in Pakistanis. There was evidence for higher seroprevalence in older age groups. CONCLUSIONS: The seroprevalence of HSV 2 was in the range of few percentage points. There were no major differences in seroprevalence by nationality. These findings add to our understanding of HSV-2 epidemiology in MENA and indicate unmet needs for sexual health and control of sexually transmitted infections. PMID- 29465658 TI - Pathways to Congenital Syphilis Prevention: A Rapid Qualitative Assessment of Barriers, and the Public Health Response, in Caddo Parish, Louisiana. AB - BACKGROUND: Congenital syphilis (CS) disproportionately affects racial and ethnic minority women, especially in the US South. Although CS is relatively easy and inexpensive to prevent through screening and treatment of pregnant women, CS cases have continued to rise and are concentrated in relatively few US counties and states. In 2010, Louisiana had the highest case rate in the country for primary, secondary, and CS, with the highest number of CS cases in northwest Louisiana, where Shreveport is located. METHODS: We conducted qualitative interviews with community members (women and frontline providers) living in Caddo Parish to obtain their views about factors that negatively impact CS prevention. RESULTS: Participants described impediments in the pathways for prevention of CS. Lack of sexual and reproductive health education, discontinuities and fragmentation in health care insurance coverage, a dearth of referral points for prenatal care, and difficulty finding prenatal care providers who accept Medicaid can delay timely and adequate care for pregnant women. Participants reported that low reimbursement for necessary injections and difficulty obtaining required medication challenged efforts to screen and treat pregnant women according to guidelines. CONCLUSIONS: Although CS is easily prevented, health system and policy obstacles in pathways to CS prevention and care may need remediation at state and local levels. PMID- 29465659 TI - Self-Reported Chlamydia and Gonorrhea Testing and Diagnosis Among Men Who Have Sex With Men-20 US Cities, 2011 and 2014. AB - BACKGROUND: Annual screening for chlamydia and gonorrhea is recommended for sexually active men who have sex with men (MSM) at anatomical sites of contact, regardless of condom use. METHODS: We assessed differences in self-reported chlamydia and gonorrhea testing and diagnosis in the past 12 months among MSM using National HIV Behavioral Surveillance data from 2011 and 2014. Men who have sex with men who had 1 or more partners in the past 12 months were included in analyses. Analyses of chlamydia and gonorrhea diagnosis data were limited to participants who reported past 12 months chlamydia and gonorrhea testing, respectively. Differences in testing and diagnosis over time were assessed using Poisson regression models with robust standard errors separately for chlamydia and gonorrhea. RESULTS: Analyses included data from 18,896 MSM (2011, n = 9256; 2014, n = 9640). Testing for chlamydia was 37% in 2011 and 47% in 2014 (prevalence ratio [PR], 1.25; 95% confidence interval [CI], 1.20-1.30) and 38% and 47% for gonorrhea (PR, 1.24; 95% CI, 1.19-1.29). Testing was higher in 2014 among most demographic subgroups. Prevalence of chlamydia diagnoses was 8% in 2011 and 11% in 2014 (PR, 1.37; 95% CI, 1.18-1.59) and of gonorrhea diagnoses was 10% in 2011 and 14% in 2014 (adjusted PR: 1.40, 95% CI, 1.23-1.60). Larger changes in diagnoses were observed among MSM in the white and "other" racial categories and those who disclosed same-sex behavior to their health care provider. CONCLUSIONS: Self-reported testing and diagnoses among MSM increased from 2011 to 2014. Increased efforts are needed to meet annual sexually transmitted disease screening recommendations among MSM at high HIV risk. PMID- 29465660 TI - Observed Treatment Responses to Short-Course Doxycycline Therapy for Rectal Lymphogranuloma Venereum in Men Who Have Sex With Men. AB - BACKGROUND: Lymphogranuloma venereum (LGV) has reestablished itself as an endemic sexually transmitted infection in the United Kingdom and elsewhere in Europe and North America over the last decade. Current guidelines suggest treatment with 21 days of doxycycline; however, the evidence base for LGV treatment including its duration is very limited. METHODS: We conducted a retrospective review in 2 central London genitourinary medicine clinics of men who have sex with men (MSM) with LGV in whom less than 21 days of doxycycline was used initially. RESULTS: Sixty MSM were treated initially with less than 21 days of doxycycline, of whom 50 (83%) were prescribed a 7-day course. Fifty percent of patients were asymptomatic, with the rest having rectal or other symptoms. Fifty-nine (97%) of 60 had a negative test of cure for LGV at a median of 31 days (7-200 days). Reinfection as opposed to treatment failure was considered likely in the patient testing positive. A second test of cure at a median of 139 days later (37-638 days) was completed in 30 patients, of whom 28 (93%) were negative for LGV. CONCLUSIONS: Seven to 14 days of doxycycline is effective in most cases of LGV with negative TOCs in 59 of 60 patients. These data suggest that 7 days of doxycycline is effective in achieving cure of rectal LGV in most MSM. There is a case for a randomized controlled trial of LGV treatment including a 7-day regimen of doxycycline. PMID- 29465661 TI - Sexually Transmitted Infection Prevalence among Homeless Adults in the United States: A Systematic Literature Review. AB - BACKGROUND: Homelessness significantly affects health and well-being. Homeless adults often experience co-occurring and debilitating physical, psychological, and social conditions. These determinants are associated with disproportionate rates of infectious disease among homeless adults, including tuberculosis, HIV, and hepatitis. Less is known about sexually transmitted infection (STI) prevalence among homeless adults. METHODS: We systematically searched 3 databases and reviewed the 2000-2016 literature on STI prevalence among homeless adults in the United States. We found 59 articles of US studies on STIs that included homeless adults. Of the 59 articles, 8 met the inclusion criteria of US-based, English-language, peer-reviewed articles, published in 2000 to 2016, with homeless adults in the sample. Descriptive and qualitative analyses were used to report STI prevalence rates and associated risk factors. RESULTS: Overall, STI prevalence ranged from 2.1% to 52.5%. A composite STI prevalence was most often reported (n = 7), with rates ranging from 7.3% to 39.9%. Reported prevalence of chlamydia/gonorrhea (7.8%) was highest among younger homeless adult women. Highest reported prevalence was hepatitis C (52.5%) among older homeless men. Intimate partner violence, injection and noninjection substance use, incarceration history, and homelessness severity are associated with higher STI prevalence. CONCLUSIONS: Homeless adults are a vulnerable population. Factors found to be associated with sexual risk were concurrently associated with housing instability and homelessness severity. Addressing STI prevention needs of homeless adults can be enhanced by integrating sexual health, and other health services where homeless adults seek or receive housing and other support services. PMID- 29465662 TI - Social Vulnerability in Congenital Syphilis Case Mothers: Qualitative Assessment of Cases in Indiana, 2014 to 2016. AB - BACKGROUND: Congenital syphilis occurs when a pregnant woman with syphilis is not diagnosed or treated and the infection is passed in utero, causing severe infant morbidity and mortality. Congenital syphilis is easily prevented if women receive timely and adequate prenatal care. Cases of congenital syphilis are considered indicators of problems in the safety net. However, maternal social and behavioral factors can impede women's care, even when providers follow guidelines. METHODS: We reviewed case interviews and maternal records for 23 congenital syphilis cases reported to the Centers for Disease Control and Prevention from Indiana between 2014 and 2016. We used qualitative methods to analyze narrative notes from maternal interviews to learn more about factors that potentially contributed to congenital syphilis cases. RESULTS: All providers followed Centers for Disease Control and Prevention and state recommendations for screening and treatment for pregnant women with syphilis. Twenty-one of 23 women had health insurance. The number of prenatal care visits women had was suboptimal; more than one third of women had no prenatal care. Nearly one third of women's only risk factor was sex with a primary male sex partner. The majority of women suffered social vulnerabilities, including homelessness, substance abuse, and incarceration. CONCLUSIONS: Despite provider adherence to guidelines and health insurance availability, some pregnant women with syphilis are unlikely to receive timely diagnosis and treatment. Pregnant women at high risk for syphilis may need additional social and material support to prevent a congenital syphilis case. Additional efforts are needed to reach the male partners of vulnerable females with syphilis. PMID- 29465664 TI - Knowledge, Practices, and Barriers to HIV Preexposure Prophylaxis Prescribing Among Washington State Medical Providers. AB - BACKGROUND: We aimed to assess HIV preexposure prophylaxis (PrEP) awareness and prescribing practices among Washington State medical providers from diverse professional disciplines and practice types. METHODS: In May 2016, we administered an anonymous online survey to licensed medical practitioners who provide primary, longitudinal, walk-in, emergency, obstetric, gynecologic, sexually transmitted infection, or family planning care. RESULTS: Of 735 eligible providers, 64.8% had heard of PrEP. Younger providers and providers with a doctor of medicine degree were more likely to be aware of PrEP compared with older providers (P = 0.0001) and providers of other training backgrounds (advanced registered nurse practitioner, doctor of osteopathic medicine, or physician assistant; P = 0.04). Among providers aware of PrEP, most frequent reported concerns about prescribing were adherence (46.0%) and costs (42.9%). Providers felt very (20.1%) or somewhat (33.8%) comfortable discussing PrEP overall, but very (26.8%) or somewhat (44.7%) uncomfortable discussing cost and insurance issues. The 124 PrEP prescribers reported a median of 2 (range, 1-175; total, 1142) patients prescribed PrEP. Prior authorizations and insurance denials had prevented prescriptions for 28.7% and 12.1% of prescribers, respectively. CONCLUSIONS: Interventions to improve PrEP access should include education to inform medical providers about PrEP, with particular attention to provider types less likely to be aware. Continued efforts to eliminate cost and insurance barriers and educate providers regarding financial resources would help improve PrEP access. PMID- 29465663 TI - A Network Analysis of Sexually Transmitted Diseases and Online Hookup Sites Among Men Who Have Sex With Men. AB - BACKGROUND: Sexually transmitted diseases (STDs) are increasing among gay, bisexual, and other men who have sex with men (MSM). Little is known about the use of websites and mobile phone applications to meet sexual partners ("hookup sites") and association with STD diagnoses. METHODS: We performed a demographic and behavioral assessment of 415 MSM presenting to the Rhode Island STD clinic. Bivariate and multivariable analyses assessed associations between using hookup sites and testing positive for syphilis, gonorrhea, or chlamydia. Venue-based affiliation networks were created to evaluate hookup sites and their association with STD diagnoses. RESULTS: Among 415 MSM, 78% reported meeting a partner online in the last 12 months, and 25% tested positive for at least one STD. Men who met partners online were more likely to be white (67% vs. 54%, P = 0.03) and have more than 10 lifetime partners (87% vs. 58%, P < 0.05). The most commonly used hookup sites included Grindr (78%), Scruff (35%), and Tinder (22%). In the multivariable analysis, only Scruff use was associated with testing positive for an STD (odds ratio, 2.28; 95% confidence interval, 1.09-4.94). However, among men who met partners online, 75% of men diagnosed as having an STD had met a sexual partner on Grindr, including 100% of those who were diagnosed as having gonorrhea. CONCLUSIONS: Use of hookup sites was nearly ubiquitous among MSM undergoing STD screening. Specific hookup sites were significantly associated with STD diagnoses among MSM. Greater efforts are needed to promote STD screening and prevention among MSM who meet partners online. PMID- 29465665 TI - Syphilis Is (Still) Here: How Must Sexually Transmitted Disease Public Health Programs Adapt? PMID- 29465666 TI - Characteristics Associated With Delivery of an Infant With Congenital Syphilis and Missed Opportunities for Prevention-California, 2012 to 2014. AB - BACKGROUND: Congenital syphilis (CS), the transmission of Treponema pallidum from mother to fetus during pregnancy, can cause adverse birth outcomes. In 2012 to 2014, the CS rate in California increased more than 200% from 6.6 to 20.3 cases per 100,000 live births. Our objectives were to identify characteristics associated with delivering an infant with CS and missed opportunities for prevention among syphilis-infected pregnant women in California. METHODS: We linked California Department of Public Health syphilis surveillance records from women aged 15 to 45 years-diagnosed from March 13, 2012, to December 31, 2014-to birth records. We compared characteristics among mothers who delivered an infant with CS (CS mothers) with mothers who delivered an infant without CS (non-CS mothers) by using chi or Fisher exact tests. To visualize gaps in prevention among syphilis-infected pregnant women, we constructed a CS prevention cascade, a figure that shows steps to prevent CS. RESULTS: During the selected period, 2498 women were diagnosed as having syphilis, and 427 (17%) linked to birth records; 164 (38%) were defined as CS mothers and 263 (62%) as non-CS mothers. Mothers with CS were more likely than non-CS mothers to have their first prenatal care visit in the third trimester. High proportions of mothers in both groups reported high-risk sexual behaviors, methamphetamine use, or incarceration (13%-29%). The CS prevention cascade showed decrements of 5% to 11% in prenatal care receipt, testing, and treatment steps; only 62% of potential CS births were prevented. CONCLUSIONS: Multifaceted efforts are needed to address gaps in the CS prevention cascade and reduce CS cases in California.

AB - BACKGROUND: This study aimed to examine the agreement between sexually transmitted infection (STI) screening using self-collected specimens and physician-collected specimens, and to investigate the acceptability of self collection for screening in an 18-month study of female sex workers in a high risk, low-resource setting. METHODS: A total of 350 female sex workers in Nairobi, Kenya, participated in a prospective study from 2009 to 2011. Women self collected a cervicovaginal specimen. Next, a physician conducted a pelvic examination to obtain a cervical specimen. Physician- and self-collected specimens were tested for Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, and Mycoplasma genitalium (MG) using Aptima nucleic acid amplification assays (Hologic). Specimens were collected at 3-month intervals over 18-month follow-up. kappa Statistics measured agreement of positivity between self-collection and physician collection. RESULTS: Baseline STI prevalence was 2.9% for N. gonorrhoeae, 5.2% for C. trachomatis, 9.2% for T. vaginalis, and 20.1% for MG in self-collected samples, and 2.3%, 3.7%, 7.2%, and 12.9%, respectively, in physician-collected samples. kappa Agreement was consistently strong (range, 0.66-1.00) for all STIs over the 18-month study period, except for MG, which had moderate agreement (range, 0.50-0.75). Most participants found self-collection easy (94%) and comfortable (89%) at baseline, with responses becoming modestly more favorable over time. CONCLUSIONS: Self collected specimen screening results showed strong agreement to clinical collected specimens, except for MG, which was consistently detected more commonly in self-collected than in physician-collected specimens. Acceptability of the self-collection procedure was high at baseline and increased modestly over time. In high-risk, low-resource settings, STI screening with self-collected specimens provides a reliable and acceptable alternative to screening with physician collected specimens.

AB - BACKGROUND: In August 2015, a nurse-led express human immunodeficiency virus (HIV)/sexually transmitted infection (STI) testing service "Test-And-Go" (TAG) for asymptomatic men who have sex with men (MSM) was implemented in a large public sexual health center in Melbourne, Australia. We aimed to compare the clients' characteristics between the TAG and routine walk-in service among asymptomatic MSM. METHODS: This study was conducted at the Melbourne Sexual Health Centre, Australia, between August 5, 2015, and June 1, 2016. General estimating equation logistic regression models were constructed to examine the association between the use of TAG service and clients' demographic characteristics, sexual behaviors, and HIV/STI positivity. Clients' consultation and waiting times for both services were calculated. RESULTS: Of the 3520 consultations, 784 (22.3%) were TAG services and 2736 (77.7%) were routine walk in services for asymptomatic MSM. Asymptomatic MSM were more likely to use the TAG service if they were born in Australia (adjusted odds ratio, 1.29; 95% confidence interval, 1.07-1.56), and had more than 6 male partners in the last 12 months (adjusted odds ratio, 1.13; 95% confidence interval, 1.08-1.58). Age, HIV status, condomless anal sex and HIV/STI positivity did not differ between the two services. The TAG service had a shorter median waiting time (8.4 minutes vs 52.9 minutes; p < 0.001) and consultation time (8.9 minutes vs 17.6 minutes; p < 0.001) than the routine walk-in service. CONCLUSIONS: Although country of birth and sexual behaviors differed between clients attending the 2 services, there were no differences in HIV and STI positivity. Importantly, the TAG service required less waiting and consultation time and hence created additional clinic capacity at the general clinic to see clients who are at higher risk.

PMID- 29465670 TI - Effect of a Rapid Test Algorithm on Linkage to Medical Care and Viral Suppression Among New Jersey Residents, 2007 to 2015. AB - BACKGROUND: Efforts to identify and link human immunodeficiency virus-infected persons to medical care are the first steps to achieving viral suppression. In the United States, the goals are to link 85% of newly diagnosed persons to medical care in 30 days or less and for 80% to become virally suppressed by 2020. Among newly diagnosed residents from 2007 to 2015, in New Jersey, we evaluated the impact of a rapid testing algorithm (RTA) on linkage to medical care and viral suppression. METHODS: This is a retrospective review of data from New Jersey's Enhanced HIV/AIDS Reporting System for residents, newly diagnosed at 13 years or older, from 2007 to 2015. We used survival analysis methods to estimate the proportion of residents and time to linkage to medical care and viral suppression. RESULTS: Of 8508 newly diagnosed residents, 60.3% and 72.3% were linked to medical care in 30 days or less and 90 days or less, respectively; 45.7% achieved viral suppression in 365 days or less. Linkage to medical care in 90 days or less and viral suppression in 365 days or less were more likely among those tested by RTA than laboratory testing. The adjusted hazard ratios for linkage to medical care, in clinical sites were 1.41, (95% confidence interval [CI], 1.22-1.63 and 1.08, 95% CI, 0.97-1.2 in community sites. The adjusted hazard ratios for viral suppression in clinical sites were 1.25 (95% CI, 1.05 1.47 and 1.16, 95% CI, 1.01-1.32, in community sites. CONCLUSIONS: Implementation of a RTA may eliminate barriers to linkage to medical care and viral suppression leading to decreased morbidity, mortality, and transmission.

AB - Vaginolysin (VLY), a cytotoxic protein produced by Gardnerella vaginalis, may contribute to bacterial vaginosis. We observed that women with G. vaginalis, low levels of lactobacilli, history of vaginal douching, higher Nugent scores, and higher vaginal pH had increased VLY. Inflammatory markers were not highly expressed with increasing VLY. Vaginolysin's role in bacterial vaginosis warrants further evaluation. PMID- 29465673 TI - Health Care Provider Perceptions of a Sexually Transmitted Infection Self-testing Program in an HIV Care Clinic. AB - BACKGROUND: Sexually transmitted infections (STIs) disproportionately affect men who have sex with men. Although clinical practice guidelines recommend routine STI screening of men who have sex with men who have high-risk behaviors, extragenital STI testing rates have been low in HIV clinics across the nation. The University of Washington STD Prevention Training Center implemented an STI self-testing program at a large HIV primary care clinic in Seattle, WA, to facilitate extragenital STI testing. METHODS: We performed a mixed-methods program evaluation to assess health care provider acceptability of the program at 9 months after implementation. Twenty-eight clinicians were invited to complete an online survey. We conducted one-on-one, semistructured interviews with 6 clinicians and a focus group with 7 members of the clinic nursing staff. Survey responses were tallied. Conventional content analysis was performed on survey comments and transcripts from the interviews and focus group. RESULTS: Ninety-one percent of clinicians were either satisfied or very satisfied with the program. Perceived advantages of the program included saving time for clinicians, overcoming patient discomfort, and increasing patient access to testing. Perceived program disadvantages included unclear responsibility of directing patients through the self-testing process and incorrect sample collection and labeling. CONCLUSIONS: Despite perceived disadvantages, the self-testing program was acceptable to clinicians and nursing staff, key population for successful program adoption. Implementation of STI self-testing programs in clinic settings could help to increase extragenital STI testing rates by removing provider and patient barriers to testing. PMID- 29465674 TI - The Etiology of Vaginal Discharge Syndrome in Zimbabwe: Results from the Zimbabwe STI Etiology Study. AB - INTRODUCTION: Symptomatic vaginal discharge is a common gynecological condition managed syndromically in most developing countries. In Zimbabwe, women presenting with symptomatic vaginal discharge are treated with empirical regimens that commonly cover both sexually transmitted infections (STIs) and reproductive tract infections, typically including a combination of an intramuscular injection of kanamycin, and oral doxycycline and metronidazole regimens. This study was conducted to determine the current etiology of symptomatic vaginal discharge and assess adequacy of current syndromic management guidelines. METHODS: We enrolled 200 women with symptomatic vaginal discharge presenting at 6 STI clinics in Zimbabwe. Microscopy was used to detect bacterial vaginosis and yeast infection. Nucleic acid amplifications tests were used to detect Neisseria gonorrhoeae, Chlamydia trachomatis, Trichomonas vaginalis, and Mycoplasma genitalium. In addition, serologic testing was performed to detect human immunodeficiency virus (HIV) infection. RESULTS: Of the 200 women, 146 (73%) had an etiology detected, including bacterial vaginosis (24.7%); N. gonorrhoeae (24.0%); yeast infection (20.7%); T. vaginalis (19.0%); C. trachomatis (14.0%) and M. genitalium (7.0%). Among women with STIs (N = 90), 62 (68.9%) had a single infection, 18 (20.0%) had a dual infection, and 10 (11.1%) had 3 infections.Of 158 women who consented to HIV testing, 64 (40.5%) were HIV infected.The syndromic management regimen covered 115 (57.5%) of the women in the sample who had gonorrhea, chlamydia, M. genitalium, or bacterial vaginosis, whereas 85 (42.5%) of women were treated without such diagnosis. CONCLUSIONS: Among women presenting with symptomatic vaginal discharge, bacterial vaginosis was the most common etiology, and gonorrhea was the most frequently detected STI. The current syndromic management algorithm is suboptimal for coverage of women presenting with symptomatic vaginal discharge; addition of point of care testing could compliment the effectiveness of the syndromic approach. PMID- 29465675 TI - App-Based Sexual Partner Seeking and Sexually Transmitted Infection Outcomes: A Cross-Sectional Study of HIV-Negative Men Who Have Sex With Men Attending a Sexually Transmitted Infection Clinic in Los Angeles, California. AB - BACKGROUND: Gay, bisexual, and other men who have sex with men (MSM) face higher rates of sexually transmitted infections (STIs) compared with the general population. The association between venues where sexual partners are met and STI transmission is dynamic and poorly understood, especially among those who use geosocial networking (GSN) apps. This study aimed to determine whether there is a difference in STI incidence between MSM who met their last sexual partner through a GSN app and MSM who met their last partner via other venues. METHODS: Data were analyzed from HIV-negative MSM attending the Los Angeles LBGT Center between August 2015 and July 2016 (n = 9499). Logistic regression models were used to investigate the relationship between STI incidence and whether or not an individual met his last partner through a GSN app. RESULTS: No relationship was detected between STI incidence and whether one's last sexual partner was met via GSN app. However, an association was detected between STI incidence and having used GSN apps to meet sexual partners in the past 3 months. A dose-response relationship was observed between the number of venues used to meet partners and testing positive for any STI (adjusted odds ratio, 1.08; 95% confidence interval, 1.02-1.14). CONCLUSIONS: The relationship between how people meet sexual partners and STI acquisition is much more nuanced than previously thought. Geosocial networking apps do not inherently expose users to high-risk reservoirs of STIs, but further understanding of the complexity of sexual networks and networking methods is warranted, given increasing rates of STIs. PMID- 29465676 TI - Previously Diagnosed HIV-Positive Persons: The Role of Centers for Disease Control and Prevention-Funded HIV Testing Programs in Addressing Their Needs. AB - BACKGROUND: Increased HIV testing efforts have resulted in retesting previously diagnosed persons. This study examined Centers for Disease Control and Prevention (CDC)-funded HIV testing programs to evaluate how the needs of previously diagnosed persons are being addressed. METHODS: The following were examined by demographic and test setting among previously diagnosed HIV-positive persons in 2015: CDC-funded HIV testing, previously diagnosed HIV positivity, current care status, and linkage to care. In addition, trends of HIV positivity and previously diagnosed HIV-positivity were examined from 2011 to 2015. RESULTS: In 2015, CDC funded 3,026,074 HIV tests, and 27,729 were HIV-positive tests. Of those, 13,528 (48.8%) were previously diagnosed persons. Only 11.6% of previously diagnosed persons reported already being in HIV care; after excluding them, 62.1% of previously diagnosed persons were linked within 90 days. In addition, the percentage of previously diagnosed persons steadily increased from 2011 (25.9%) to 2015 (34.1%; P < 0.001). CONCLUSIONS: Almost half of all HIV-positive tests were among previously diagnosed persons, but only 11.6% were already in HIV care. Linkage is necessary among persons who already know their HIV status because they either were never linked or need to be reengaged into care. Barriers in linkage and retention among this group also need to be addressed. PMID- 29465677 TI - Patterns of Sexual Behavior and Sexually Transmitted Infections in Young Men Who Have Sex With Men. AB - PURPOSE: Young men who have sex with men (MSM) are at an increased risk for sexually transmitted infections (STIs). Recent research has documented the importance of understanding the multidimensional nature of sexual risk behavior; however, little is known about how multidimensional patterns of sexual behavior among MSM may be associated with STIs. METHOD: This study applies latent class analysis to data from a large, HIV- sample of 18- to 25-year-old MSM recruited from social and sexual networking Web sites (N = 5965; 76% white, 11% Latino, 5% black, 4% Asian, 4% other; 74% homosexual, 21% bisexual, 1% heterosexual, 3%, unsure/questioning 1% other) to uncover multidimensional patterns of past-year sexual behaviors, partner factors, and protective behavior and their associations with self-reported STI diagnosis. RESULTS: We selected a model with 8 classes, with nearly half of participants belonging to a class marked by multiple behaviors with more than 1 partner, and smaller numbers of individuals in classes with a smaller number of behaviors, romantic relationships, and sexual inactivity. Class membership was associated with recent STI diagnosis, with classes marked by no penetrative sex or receptive anal sex with consistent condom use having lower prevalence than those with inconsistent condom use, including those engaging in only insertive anal sex. CONCLUSIONS: Findings suggest heterogeneity of behaviors within MSM and that prevention messages may be more effective if they are tailored to individuals' patterns of sexual behavior, as well as demographic and sociocontextual factors. PMID- 29465678 TI - Men Who Have Sex With Men-Identification Criteria and Characteristics From the National Health and Nutrition Examination Survey, 1999 to 2014. AB - OBJECTIVES: This study aimed to provide identification criteria for men who have sex with men (MSM), estimate the prevalence of MSM behavior, and compare sociodemographics and sexually transmitted disease risk behaviors between non-MSM and MSM groups using data from a nationally representative, population-based survey. METHODS: Using data from men aged 18 to 59 years who took part in the National Health and Nutrition Examination Survey (NHANES), 1999 to 2014, detailed criteria were developed to estimate MSM behavior-at least one lifetime same-sex partner (MSM-ever), at least one same-sex partner in the past 12 months (MSM current), and at least one lifetime and zero same-sex partners in the past 12 months (MSM-past). RESULTS: The estimated prevalence of MSM-ever was 5.5%-of these, 52.4% were MSM-current and 47.1% were MSM-past. Furthermore, MSM-ever are a nonhomogenous subpopulation, for example, 70.4% of MSM-current identified as homosexual and 71.2% of MSM-past identified as heterosexual (P < 0.001). CONCLUSIONS: The prevalence of MSM behavior identified here is similar to other published estimates. This is also the first article, to our knowledge, to use National Health and Nutrition Examination Survey data to compare MSM by 2 recall periods (recent vs. lifetime) of last same-sex sexual behavior. PMID- 29465679 TI - A Cluster Randomized Evaluation of a Health Department Data to Care Intervention Designed to Increase Engagement in HIV Care and Antiretroviral Use. AB - BACKGROUND: Many US health departments have implemented Data to Care interventions, which use HIV surveillance data to identify persons who are inadequately engaged in HIV medical care and assist them with care reengagement, but the effectiveness of this strategy is uncertain. METHODS: We conducted a stepped-wedge, cluster-randomized evaluation of a Data to Care intervention in King County, Washington, 2011 to 2014. Persons diagnosed as having HIV for at least 6 months were eligible based on 1 of 2 criteria: (1) viral load (VL) greater than 500 copies/mL and CD4 less than 350 cells/MUL at the last report in the past 12 months or (2) no CD4 or VL reported to the health department for at least 12 months. The intervention included medical provider contact, patient contact, and a structured individual interview. Health department staff assisted patients with reengagement using health systems navigation, brief counseling, and referral to support services. We clustered all eligible cases in the county by the last known medical provider and randomized the order of clusters for intervention, creating contemporaneous intervention and control periods (cases in later clusters contributed person-time to the control period at the same time that cases in earlier clusters contributed person-time to the intervention period). We compared the time to viral suppression (VL <200 copies/mL) for individuals during intervention and control periods using a Cox proportional hazards model. RESULTS: We identified 997 persons (intention to treat [ITT]), 18% of whom had moved or died. Of the remaining 822 (modified ITT), 161 (20%) had an undetectable VL reported before contact and 164 (20%) completed the individual interview. The hazard ratio (HR) for time to viral suppression did not differ between the intervention and control periods in ITT (HR, 1.21 [95% confidence interval, 0.85-1.71]) or modified ITT (HR, 1.18 [95% confidence interval, 0.83 1.68]) analysis. CONCLUSIONS: The Data to Care intervention did not impact time to viral suppression. PMID- 29465680 TI - Genital Wart and HPV Prevalence in Males in the United States from Penile Swabs: Results from NHANES. AB - INTRODUCTION: Human papillomavirus (HPV) is a common sexually transmitted infection in the US that can lead to both malignant (high risk) and benign (low risk) findings. These low risk findings include both genital condyloma, anal warts, and adult or juvenile papillomatosis, which are directly attributable to subtypes HPV 6 and HPV 11. We aim to estimate the prevalence of genital wart infections in males in the US population using a nationwide sample. METHODS: The NHANES database was queried for all men 18-59 years old during the years 2013 2014. During these years, the survey included penile swabs that were tested for HPV infection from 37 subtypes using PCR. Information was also obtained regarding patient reported history of having a genital wart infection previously. RESULTS: A total of 1,757 men had information regarding HPV DNA. Fifty-three men tested positive for HPV 6 or HPV 11 DNA. This corresponds to an estimated prevalence of 2.9% (95% CI 2.2-3.8) of men aged 18-59 years. In addition, 2.2% (95% CI 1.5-3.3) of men reported a history of genital wart infection. There was no significant association with genital HPV DNA detection with age. Increasing number of sexual partners was associated with higher rates of both genital warts and HPV 6 and HPV 11 DNA. CONCLUSIONS: The estimated prevalence of genital HPV DNA in the US male population is 2.9%. This burden of disease could potentially be lowered with increased usage of quadrivalent and nonavalent vaccinations. PMID- 29465681 TI - A Population-Based Study to Compare Treatment Outcomes Among Women With Urogenital Chlamydial Infection in Washington State, 1992 to 2015. AB - BACKGROUND: United States guidelines recommend azithromycin or doxycycline for chlamydia (Chlamydia trachomatis [CT]) treatment. These therapies are similarly efficacious for urogenital infections when outcomes are measured 7 to 42 days after treatment, although doxycycline may be superior for rectal infections. Some investigators have suggested that persistent rectal infections may lead to autoinfection of the urogenital tract, potentially resulting in higher rates of recurrent infection in azithromycin-treated women. METHODS: We used Washington State surveillance data to identify women 14 years or older with urogenital CT (1992-2015) treated with azithromycin or doxycycline. We defined persistent/recurrent CT as a repeat positive CT test result 14 to 180 days after treatment of the initial infection. We used log binomial regression to estimate the adjusted relative risk (aRR) of persistent/recurrent infection associated with treatment with azithromycin versus doxycycline. RESULTS: From 1992 to 2015, there were 268,596 reported cases of urogenital CT, including 168,301 (63%) who received azithromycin and 66,432 (25%) who received doxycycline. The risk of persistent/recurrent urogenital CT was 6.7% and 4.7% in azithromycin- and doxycycline-treated cases, respectively (P < 0.001). Adjusting for age, race/ethnicity, year, pregnancy status, jurisdiction reporting, reason for examination, and gonorrhea coinfection, azithromycin-treated women were significantly more likely to have persistent/recurrent urogenital CT than doxycycline-treated women (aRR, 1.24; 95% confidence interval [CI], 1.19-1.30). Adjusting the retesting window to 21 to 180 days (aRR, 1.24; 95% CI, 1.19-1.30) and 28 to 180 days (aRR, 1.25; 95% CI, 1.19-1.30) did not alter our primary findings. CONCLUSIONS: Persistent/recurrent urogenital CT may be more common among women treated with azithromycin than with doxycycline. The reason for this difference is uncertain and is an important area of future investigation. PMID- 29465682 TI - Variability in Condom Use Trends by Sexual Risk Behaviors: Findings from the 2003 2015 National Youth Risk Behavior Surveys. AB - OBJECTIVE: This study aimed to examine variability in condom use trends by sexual risk behavior among US high school students. METHODS: Data were from the 2003 2015 national Youth Risk Behavior Surveys conducted biennially among a nationally representative sample of students in grades 9 to 12. We used logistic regression to examine variability in trends of condom use during last sexual intercourse among female and male students by 4 sexual risk behaviors: drank alcohol or used drugs before last sexual intercourse, first sexual intercourse before age 13 years, 4 or more sex partners during their life, and 2 or more sex partners during the past 3 months. RESULTS: Between 2003 and 2015, significant declines in self-reported condom use were observed among black female (63.6% in 2003 to 46.7% in 2015) and white male students (69.0% in 2003 to 58.1% in 2015). Among female students, declines in self-reported condom use were significant only among those who drank or use drugs before last sexual intercourse, had 4 or more sex partners during their life, or had 2 or more sex partners during the past 3 months. There was a significant interaction between trends in condom use and first sexual intercourse before age 13 years, suggesting more pronounced declines among female students who initiated first sexual intercourse before age 13 years compared with their female peers. Trends did not vary by sexual risk behavior for male students. CONCLUSIONS: Results suggest that declines in self-reported condom use have occurred among female students at greater risk for acquiring a sexually transmitted disease. PMID- 29465683 TI - Chemsex Among Men Who Have Sex With Men: a Sexualized Drug Use Survey Among Clients of the Sexually Transmitted Infection Outpatient Clinic and Users of a Gay Dating App in Amsterdam, the Netherlands. AB - OBJECTIVES: Chemsex (i.e., drug use during sex) is practiced by some men who have sex with men (MSM) and is associated with high-risk behavior. In a cross sectional study at the sexually transmitted infection (STI) clinic of Amsterdam, we explored chemsex practices, risk behavior, and STI prevalence. METHOD: A survey on chemsex (gamma-hydroxybutyrate, crystal methamphetamine, and/or mephedrone) was offered to clinic clients during routine STI screening and to Amsterdam users of a gay online dating app. Associations were assed using chi test and multivariable regression. RESULTS: Chemsex in the past 6 months was practiced by 866 (17.6%) of 4925 MSM clients and by 159 (1.5%) of 10857 non-MSM clients. Among gay dating app users, the proportion that reported chemsex engagement was higher than among MSM visiting the STI clinic (29.3% [537/1832] vs. 17.6%; P < 0.001). Chemsex was a significant risk factor for bacterial STI in HIV-negative MSM visiting the STI clinic (adjusted odd ratio, 1.5; 95% confidence interval, 1.2-1.8), but not in HIV-positive MSM. A majority practiced chemsex once a month or less, and 87.0% reported sex without drug use in the past month. CONCLUSIONS: In Amsterdam, chemsex is frequently practiced and significantly associated with bacterial STI in HIV-negative MSM but not in HIV-positive MSM. Future prevention strategies to reduce STI incidence should especially target HIV negative MSM engaging in chemsex.

AB - Men and women attending family planning and sexually transmitted disease clinics for sexually transmitted infection screening in 2012 to 2013 were tested for Trichomonas vaginalis (TV) using a sensitive nucleic acid amplification test. T. vaginalis prevalence in urogenital samples was 11.3% in 77,740 women and 6.1% in 12,604 men, and increased with age in both sexes. PMID- 29465685 TI - Ciprofloxacin May be Efficacious in Treating Wild-Type Gyrase A Genotype Neisseria gonorrhoeae Infections. PMID- 29465686 TI - Prevalence and Detection of Trichomonas vaginalis in HIV-Infected Pregnant Women. AB - BACKGROUND: Trichomonas vaginalis is a sexually transmitted infection associated with increased transmission of HIV and significant adverse birth outcomes; culture and polymerase chain reaction (PCR) are commonly used in diagnosis. METHODS: Consenting HIV-infected pregnant women were recruited from clinics in South Africa and screened for T. vaginalis using PCR. Polymerase chain reaction positive women provided an additional sample for culture. We compared T. vaginalis detection between PCR and culture, and investigated how PCR cycle threshold (Ct) values differ among culture results. RESULTS: A total of 359 women were enrolled and 76 (20%) tested T. vaginalis PCR positive. Cultures were obtained from 61 of the PCR-positive women, and 38 (62%) were culture positive. The median baseline Ct of the PCR-positive/culture-positive group was 22.6 versus 38.0 among those who were PCR positive/culture negative (P < 0.001). Culture positive cases had lower Ct values (higher DNA load); a Ct value less than 30 predicted positivity with a sensitivity of 97% and a specificity of 96%. CONCLUSIONS: Culture was positive in roughly half of PCR-positive cases. The culture-negative cases had significantly higher Ct values, indicating a lower concentration of T. vaginalis DNA. A Ct value of 30 provides a reliable threshold for predicting culture positivity. The clinical significance of culture-negative infections detected by PCR is still unclear. PMID- 29465687 TI - Molecular Characterization of Markers Associated With Antimicrobial Resistance in Neisseria gonorrhoeae Identified From Residual Clinical Samples. AB - BACKGROUND: The emergence and spread of antimicrobial-resistant (AMR) Neisseria gonorrhoeae (NG) is a major public health concern. In the era of nucleic acid amplifications tests, rapid and accurate molecular approaches are needed to help increase surveillance, guide antimicrobial stewardship, and prevent outbreaks. METHODS: Residual urethral swabs, collected prospectively in the Baltimore City Health Department during a 6-month period, were analyzed by real-time polymerase chain reaction assays for NG DNA and AMR determinants to fluoroquinolones, penicillin, and extended-spectrum cephalosporins. RESULTS: N. gonorrhoeae DNA was detected in 34.8% (73/210) of samples, including 67.3% (68/101) of the swabs that had been previously identified as NG positive by culture. Markers associated with decreased susceptibility to fluoroquinolones were detected in 22.4% of the polymerase chain reaction NG-positive samples. The rate of penicillinase producing NG was very low (1.6%), and no markers associated with decreased susceptibility to extended-spectrum cephalosporins were detected in this cohort of men using the AMR assays herein described. CONCLUSIONS: Detection of molecular markers associated with AMR in NG can be performed directly from residual clinical samples, although the recovery rate of adequate DNA for molecular testing from these samples can be suboptimal. A high number of samples with mutations associated with decreased susceptibility to fluoroquinolones were identified. PMID- 29465688 TI - Prevalence of Rectal Chlamydial and Gonococcal Infections: A Systematic Review. AB - We undertook a systematic review to examine rectal Chlamydia trachomatis (Ct) and Neisseria gonorrhoeae (Ng) infections in women and men who have sex with men (MSM). English-language publications measuring rectal Ct or Ng prevalence using nucleic acid amplification tests were eligible. Searching multiple electronic databases, we identified 115 eligible reports published between January 2000 and November 2016. Overall, the prevalence of rectal Ct (9%) was higher than that of rectal Ng (4.7%). Rectal Ct prevalence was similar in MSM (9%) and women (9.2%), whereas rectal Ng prevalence was higher in MSM (6.1%) than in women (1.7%). Generally, rectal Ct prevalence was similar in sexually transmitted disease clinics (9.1%) and nonsexual health clinics (8.6%), whereas rectal Ng prevalence was somewhat lower in sexually transmitted disease clinics (4.5%) than in nonsexual health clinics (6%). These infections seem to be relatively common across a range of populations and clinical settings, highlighting the need for additional research on these preventable, treatable conditions. PMID- 29465689 TI - Expedited Partner Therapy: Pharmacist Refusal of Legal Prescriptions. AB - BACKGROUND: Expedited partner therapy (EPT) is an effective strategy for partner management of sexually transmitted infections. Some states, including Wisconsin, allow EPT prescriptions to be filled without a patient name. This study determined the refusal rates of nameless EPT prescriptions in Milwaukee pharmacies. METHODS: In this cross-sectional study, 3 trained research assistants of different age, sex, and race posed as "patients" and visited 50 pharmacy locations from one pharmacy chain in Milwaukee County, WI, to fill nameless EPT prescriptions. A chi test was used to compare demographics of patients, pharmacists, and pharmacies. Multiple logistic regression was used to identify factors associated with prescription refusal. RESULTS: Twenty-nine (58%) of 50 nameless EPT prescriptions were refused. Univariate analysis showed that prescriptions were more likely to be refused if the pharmacy was in the suburbs (77%) compared with Milwaukee city (43%; P = 0.01), if the pharmacist was older than the patient (82%) compared with being younger (46%) or within the same age group (33%; P = 0.01 for both), and if the patient was white (78%) compared with nonwhite (47%; P = 0.03). Multivariable regression revealed significantly higher refusals for pharmacies located in the suburbs compared with the city (odds ratio, 5.3; 95% confidence interval, 1.4-20.3; P = 0.03) and in patients who were white compared with nonwhite (odds ratio: 4.8; 95% confidence interval, 1.2-19.8; P = 0.01). CONCLUSIONS: More than half of nameless EPT prescriptions were refused in Milwaukee county pharmacies, more frequently at suburban pharmacies and for white patients. Increased pharmacist education regarding EPT is essential to help combat the sexually transmitted infection crisis.

AB - This study compared sexual risk behaviors and sexually transmitted infection prevalence among African American women who have sex with women, women who have sex with men with a single male partner, women who have sex with men with 4 or more male partners, and women who have sex with women and men at a sexually transmitted disease clinic. The results suggest that, despite differences in prevalence, there was not a clear continuum of sexually transmitted infection risk among African American women in the study; all women were at risk. PMID- 29465690 TI - Conceptualizing Geosexual Archetypes: Mapping the Sexual Travels and Egocentric Sexual Networks of Gay and Bisexual Men in Toronto, Canada. AB - BACKGROUND: There are complex, synergistic, and persistent sexually transmitted infection (STI) epidemics affecting gay, bisexual and other men who have sex with men (gbMSM) in every major urban centre across North America. We explored the spatial architecture of egocentric sexual networks for gbMSM in Toronto, Canada. METHODS: Our integrative mixed methods study included in-depth interviews with 31 gbMSM between May and July 2016. During interviews, participants mapped their egocentric sexual network for the preceding 3 months geographically. At the end, a self-administered survey was used to collect sociodemographic characteristics, online technology use, and STI testing and history. RESULTS: We identified 6 geosexual archetypes: hosters, house-callers, privates, rovers, travellers, and geoflexibles. Hosters always, or almost always (>=80%), hosted sex at their home. House-callers always, or almost always (>=80%), had sex at their partner's home. Rovers always or almost always (>=80%) had sex at public venues (eg, bath houses, sex clubs) and other public spaces (eg, parks, cruising sites). Privates had sex in private-their own home or their partner's (part hoster, part house-caller). Travellers had sex away from their home, either at a partner's home or some other venue or public space (part house-caller, part rover). Geoflexibles had sex in a variety of locations-their home, their partner's home, or public venues. All hosters and rovers, and to a lesser extent, geoflexibles, reported a history of syphilis and human immunodeficiency virus. CONCLUSIONS: Prioritizing interventions to hosters, rovers, and geoflexibles may have an important impact on reducing STI transmission. PMID- 29465692 TI - Molecular Typing and Macrolide Resistance of Syphilis Cases in Manitoba, Canada, From 2012 to 2016. AB - BACKGROUND: The province of Manitoba, Canada, with a population of approximately 1.3 million, has been experiencing increased incidence of syphilis cases since 2015. In this study, we examined the detection of Treponema pallidum DNA in 354 clinical samples from 2012 to 2016, and determined molecular types and mutations conferring resistance to azithromycin in the polymerase chain reaction (PCR) positive samples. METHODS: T. pallidum DNA detection was done by PCR amplification of tpp47, bmp, and polA genes. Syphilis serology results were reviewed for the PCR-positive cases. Molecular typing of syphilis strains was done by analysis of the T, pallidum arp, tpr, and tp0548 gene targets as well as partial sequencing of the 23S rRNA gene for azithromycin resistance. RESULTS: Of the 354 samples tested, 74 individual cases were PCR positive. A result from the treponemal antibody chemiluminescent microparticle immunoassay test was positive in 72 of these cases and that from the Venereal Disease Research Laboratory testing was positive in 66. Mutations conferring resistance to azithromycin were found in all 74 PCR-positive samples. Molecular typing was completed on 57 PCR positive samples, and 12 molecular types were identified with 14d/g found in 63.2%. Increased strain diversity was observed with 8 molecular types detected in 2016, whereas only 2 to 3 types were found in 2012 to 2014. A patient with 2 episodes of infection 9 months apart caused by different molecular strain types was also identified. CONCLUSIONS: The finding of an increase in genetic diversity in the strains in this study and an increase in macrolide resistance compared with previous Canadian reports highlighted the need for continued surveillance including strain characterization. PMID- 29465693 TI - Scaling Up Human Immunodeficiency Virus Screening and Antiretroviral Therapy Among Men Who Have Sex With Men to Achieve the 90-90-90 Targets in China. AB - INTRODUCTION: The Joint United Nations Programme on human immunodeficiency virus (HIV)/acquired immune deficiency syndrome has proposed the 90-90-90 targets by 2020. Human immunodeficiency virus epidemic is spreading rapidly among men who have sex with men (MSM) in China. This study investigates how the scale-up of HIV testing and treatment in achieving the targets and its cost-effectiveness. METHODS: We constructed a compartmental model to forecast the HIV epidemic in Chinese MSM based on various "test-and-treat" scale-up scenarios. We assessed their cost effectiveness based on the cost for each HIV infection, death, and disability-adjusted life years (DALYs) prevented by the scale-up. RESULTS: If the current epidemic continued, HIV prevalence among Chinese MSM would increase from 9.2% in 2016 to 12.6% (9.2-15.6%) in 2020 and 16.2% (11.3-20.0%) in 2025. By 2020, 49.2% of infected MSM would be diagnosed and 40.1% of whom on treatment, falling short of the 90-90-90 targets, so would be even by 2025. To achieve these targets by 2020, additional 850,000 HIV screening tests and 112,500 person-years of antiretroviral treatment (ART) annually are necessary. This spending is US $478 million during 2016 to 2020, which almost tripled the status quo. However, by delaying to 2025, an investment of US $1210 million over 2016 to 2025 corresponding to 52% increase to the status quo, will enable extra 340,000 HIV screening tests and 60,000 person-year on ART annually. In both scenarios, the incremental cost-effectiveness ratio was US $733 to 960 for each DALY prevented, indicating highly cost-effective scenarios. CONCLUSIONS: Achieving the 90-90-90 targets by 2020 requires steep increase in investment, but delaying the targets to 2025 is practical and cost-effective.

AB - Among men who have sex with men traveling internationally, self-reported hepatitis B virus (HBV) vaccination prevalence was 77% and less prevalent among older men and those with HBV infection. The HBV infection prevalence was 25% and was associated with older age and HIV infection. Testing for chronic infection, universal vaccination, and treatment for populations with multiple risks is needed. PMID- 29465695 TI - Extragenital Chlamydia and Gonorrhea in Young Black Men Who Have Sex With Men: Missed Treatment Opportunities for Human Immunodeficiency Virus-Infected Men Who Have Sex With Men? AB - OBJECTIVES: This study of young black men who have sex with men (YBMSM) assessed the prevalence of extragenital chlamydia and gonorrhea among those testing negative for urethral infections, and compared prevalence of both by human immunodeficiency virus (HIV) status. METHODS: A convenience sample of 609 YBMSM was recruited for a cross-sectional study from 2 sexual health clinics located in Jackson, MS. To detect Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG), nucleic acid amplification testing was performed on urine, rectal swabs, and oral swabs. OraSure was used to detect HIV. RESULTS: Seventy-three percent of all chlamydia infections and 77% of gonorrhea infections were found from anal and oral swabs in the absence of urethral positivity. Compared with HIV-uninfected men, HIV-infected men were significantly more likely to have pharyngeal chlamydia (P = 0.03), multiple CT infections (P = 0.02), rectal NG (P < 0.001), multiple NG infections (P = 0.04), both CT/NG rectal infections (P = 0.001). CONCLUSIONS: As much as three quarters of all chlamydia and gonorrhea infections may be missed when only urine-based nucleic acid amplification testing is used to screen YBMSM for bacterial sexually transmitted infections. These missed opportunities for diagnosis may be particularly likely among HIV-infected YBMSM. PMID- 29465696 TI - Integrated Hepatitis C Testing and Linkage to Care at a Local Health Department Sexually Transmitted Disease Clinic: Determining Essential Resources and Evaluating Outcomes. AB - Guidance about integration of comprehensive hepatitis C virus (HCV)-related services in sexually transmitted disease (STD) clinics is limited. We evaluated a federally funded HCV testing and linkage-to-care program at an STD clinic in Durham County, North Carolina. During December 10, 2012, to March 31, 2015, the program tested 733 patients for HCV who reported 1 or more HCV risk factor; 81 (11%) were HCV-infected (ie, HCV antibody-positive and HCV ribonucleic acid positive). Fifty-one infected patients (63%) were linked to care. We concluded that essential program resources include reflex HCV ribonucleic acid testing; a dedicated bridge counselor to provide test results, health education, and linkage to-care assistance; and referral relationships for local HCV management and treatment. PMID- 29465698 TI - Enhanced Molecular Typing of Treponema pallidum subspecies pallidum Strains From 4 Italian Hospitals Shows Geographical Differences in Strain Type Heterogeneity, Widespread Resistance to Macrolides, and Lack of Mutations Associated With Doxycycline Resistance. AB - BACKGROUND: Although syphilis rates have been relatively high in Italy for more than 15 years, no data on the molecular types of Treponema pallidum subspecies pallidum circulating in this country are yet available. Likewise, no data on how widespread is resistance to macrolide or tetracycline antibiotics in these strains exist. Such data would, however, promote comprehensive studies on the molecular epidemiology of syphilis infections in Italy and inform future interventions aiming at syphilis control in this and other European countries. GOALS AND STUDY DESIGN: Swabs from oral, genital, cutaneous, or anal lesions were obtained from 60 syphilis patients attending dermatology clinics in Milan, Turin, Genoa, and Bologna. Molecular typing of T. pallidum DNA was performed to provide a snapshot of the genetic diversity of strains circulating in Northern Italy. Samples were also screened for mutations conferring resistance to macrolides and tetracyclines. RESULTS: T. pallidum DNA was detected in 88.3% (53/60) of the specimens analyzed. Complete and partial T. pallidum typing data were obtained for 77.3% (41/53) and 15.0% (8/53) of samples, respectively, whereas 4 samples could not be typed despite T. pallidum DNA being detected. The highest strain type heterogeneity was seen in samples from Bologna and Milan, followed by Genoa. Minimal diversity was detected in samples from Turin, despite the highest number of typeable samples collected there. Resistance to macrolides was detected in 94.3% (50/53) of the strains, but no known mutations associated with tetracycline resistance were found. CONCLUSIONS: Genetic diversity among T. pallidum strains circulating in Northern Italy varies significantly among geographical areas regardless of physical distance. Resistance to macrolides is widespread. PMID- 29465699 TI - Early Evidence of the Effectiveness of the Human Papillomavirus Vaccination Program Against Anogenital Warts in Manitoba, Canada: A Registry Cohort Study. AB - BACKGROUND: We assessed the effectiveness of the quadrivalent human papillomavirus vaccine (qHPV) vaccination program in Manitoba, Canada, in reducing incident anogenital warts (AGWs) and to what extent effectiveness depends on age at vaccination and number of doses. METHODS: Female participants 9 years or older who received the qHPV in Manitoba between September 2006 and March 2013 (n = 31,464) through the publicly funded school-based program and a high risk catch-up program were included. They were matched on age and area of residence to unvaccinated female participants. Information on incident AGWs was obtained from provincial administrative databases using validated algorithms. Using stratified Cox regression models, we estimate hazard ratios (HRs) for the association between qHPV and AGWs. RESULTS: For female participants vaccinated at age 18 years or younger, receipt of qHPV was associated with a 40% reduction in AGW risk (HR, 0.6; 95% confidence interval [CI], 0.4-0.8). Further adjustment for socioeconomic and medical history did not alter this estimate. For women vaccinated at age 19 years or older, we saw an increase in AGW incidence, especially among those who were sexually active (HR, 2.8; 95% CI, 2.1-3.7). Among female participants vaccinated at age 18 years or younger, risk of AGWs was lowest among those who received 3 doses, corresponding to a vaccine effectiveness of 56% (95% CI, 30%-70%). For women vaccinated at older age, risk of AGWs remained increased regardless of the number of doses. CONCLUSIONS: Women vaccinated at an older (>=19 years) age may be less protected against AGWs, particularly if sexually active before vaccine administration. Further efforts should be targeted at increasing vaccine uptake among preadolescents before the initiation of sexual activity.

PMID- 29465701 TI - Optimizing Screening for Sexually Transmitted Infections in Men Using Self Collected Swabs: A Systematic Review. AB - BACKGROUND: Sexually transmitted infection (STI) rates are increasing in the United States while funding for prevention and treatment programs has declined. Sample self-collection for STI testing in men may provide an acceptable, easy, rapid, and potentially cost-effective method for increasing diagnosis and treatment of STIs. METHODS: We conducted a systematic review of articles assessing self-collection of anal, oral, or genital swab samples among adult men for detection of STIs and/or human papillomavirus-related dysplasia. We searched for English-language articles in which men 18 years or older were recruited to participate. RESULTS: Our literature search resulted in 1053 citations, with 20 meeting inclusion criteria. Self-collection methods were highly sensitive and comparable with clinician collection for detection of multiple STI pathogens. However, self-collected samples were less likely to be of adequate quality for anorectal cytology and less sensitive for detection of anal intraepithelial neoplasia than clinician-collected samples. Self-collection was highly acceptable. Overall, studies were small and heterogeneous and used designs providing lower levels of evidence. CONCLUSIONS: Self-collection methods are a viable option for collecting samples for STI testing in adult men based on their high feasibility, acceptability, and validity. Implementation of self-collection procedures in STI testing venues should be performed to expand opportunities for STI detection and treatment. PMID- 29465702 TI - Narrative Review: Assessment of Neisseria gonorrhoeae Infections Among Men Who Have Sex With Men in National and Sentinel Surveillance Systems in the United States. AB - To assess trends in Neisseria gonorrhoeae among gay, bisexual, and other men who have sex with men (MSM), we reviewed existing and published gonorrhea surveillance data in the United States. Data identified in this review include the following: national gonorrhea case report data and data from 3 other surveillance programs, the Gonococcal Isolate Surveillance Project (GISP), the STD Surveillance Network (SSuN), and National HIV Behavioral Surveillance.Rates of reported cases of gonorrhea among men increased 54.8% in 2006 to 2015 compared with a 2.6% increase among women. Since 2012, the rate of reported gonorrhea cases among men surpassed the rate among women; the male-to-female case rate ratio increased from 0.97 in 2012 to 1.31 in 2015. The proportion of gonococcal urethral isolates collected in the Gonococcal Isolate Surveillance Project that were collected from MSM increased from 21.5% to 38.1% in 2006 to 2015. In 2009 to 2015, the percent of MSM who tested positive for rectal and oropharyngeal gonorrhea in sexually transmitted disease (STD) clinics increased by 73.4% and 12.6%, respectively. Estimated rates of gonorrhea among MSM increased by 151% in 2010 to 2015 in jurisdictions participating in the STD Surveillance Network. Data from the National HIV Behavioral Surveillance demonstrate that testing for gonorrhea among MSM increased by 23.1% between 2011 and 2014.Together, surveillance data suggest a disproportionate burden of gonorrhea among MSM in the United States and suggest increases in both screening and disease in recent years. Because each data source has inherent limitations and biases, examining these data from different systems together strengthens this conclusion. PMID- 29465703 TI - An Exploration of Factors Impacting Preexposure Prophylaxis Eligibility and Access Among Syringe Exchange Users. AB - BACKGROUND: In 2015, approximately 50,000 new HIV infections occurred in the United States, 2,400 of which were attributable to injection drug use. Preexposure prophylaxis (PrEP) has the potential to curb HIV acquisition; however, uptake remains low among persons who inject drugs (PWID). The purpose of the study is to describe PrEP eligibility, willingness to use PrEP, and ability to access PrEP among PWID recruited from a pilot program that paired screening and treatment of sexually transmitted infections with mobile syringe exchange program (SEP) services. METHODS: Between 2015 and 2016, 138 PWID 18 years or older were recruited from a mobile SEP in Camden, New Jersey. Participants completed a survey assessing sociodemographics and HIV risk and underwent chlamydia and gonorrhea screening. Centers for Disease Control clinical guidelines were used to calculate PrEP eligibility. Differences by sex were examined using inferential statistics. RESULTS: Most women (95.4%) and men (84.5%) were considered PrEP eligible (P < 0.04). More women than men were willing to take PrEP (88.9% vs. 71.0%; P < 0.02). Participants reported substantial barriers to PrEP including feeling embarrassed (45.0%) or anxious (51.6%) about taking PrEP, nondisclosure to partners (51.4%), limited engagement with health care providers where PrEP might be provided (43.8%), and lacking health insurance (32.9%). CONCLUSIONS: Despite reporting behavior that warrants the use of PrEP to prevent HIV and finding the concept acceptable, PWID face multiple barriers to PrEP access. Without tailored interventions to promote PrEP, uptake will likely remain suboptimal. Packaging PrEP with SEP services could provide a viable option for reaching eligible and interested PWID.

Most patients (81%) with pelvic inflammatory disease were diagnosed as having chlamydia alone. Three treatment failures were seen in patients treated with ofloxacin. PMID- 29465705 TI - Non-Vaccine-Type Human Papillomavirus Prevalence After Vaccine Introduction: No Evidence for Type Replacement but Evidence for Cross-Protection. AB - BACKGROUND: We examined non-vaccine-type human papillomavirus (HPV) prevalence in a community before and during the first 8 years after vaccine introduction, to assess for (1) type replacement with any non-vaccine-type HPV and (2) cross protection with non-vaccine types genetically related to vaccine-type HPV. METHODS: Sexually experienced 13- to- 26-year-old women were recruited for 3 cross-sectional studies from 2006 to 2014 (N = 1180). Outcome variables were as follows: (1) prevalence of at least 1 of 32 anogenital non-vaccine-type HPVs and (2) prevalence of at least 1 HPV type genetically related to HPV-16 and HPV-18. We determined changes in proportions of non-vaccine-type HPV prevalence across the study waves using logistic regression with propensity score inverse probability weighting. RESULTS: Vaccine initiation rates increased from 0% to 71.3%. Logistic regression demonstrated that from 2006 to 2014, there was no increase in non-vaccine-type HPV among vaccinated women (adjusted odds ratio [AOR], 1.02; 95% confidence interval [CI], 0.73-1.42), but an increase among unvaccinated women (AOR, 1.88; 95% CI, 1.16-3.04). Conversely, there was a decrease in types genetically related to HPV-16 among vaccinated (AOR, 0.57; 95% CI, 0.38-0.88) but not unvaccinated women (AOR, 1.33; 95% CI, 0.81-2.17). CONCLUSIONS: We did not find evidence of type replacement, but did find evidence of cross-protection against types genetically related to HPV-16. These findings have implications for cost-effectiveness analyses, which may impact vaccine related policies, and provide information to assess the differential risk for cervical cancer in unvaccinated and vaccinated women, which may influence clinical screening recommendations. The findings also have implications for public health programs, such as health messaging for adolescents, parents, and clinicians about HPV vaccination. PMID- 29465706 TI - Creating Innovative STI Testing Options for University Students: the Impact of an STI Self-testing Program. AB - BACKGROUND: National-level data suggest that STI testing rates among young adults are low. The purpose of this study was to evaluate the acceptability of an STI self-testing program at a university health center. Few evaluations have been conducted on the acceptability of collegiate self-testing programs and their effect on testing uptake. METHODS: To assess acceptability and uptake of self testing (urine and SCVS), we conducted a brief self-administered survey of students accessing a large US-based university health center from January - December 2015. RESULTS: In 2015, University Health Services experienced a 28.5% increase in CT/GC testing for males and 13.7% increase in testing for females compared to 2013 (baseline). In 2015, 12.4% of males and 4.8% of females tested positive for CT/GC via clinician testing, while 12.9% of males and 12.4% of females tested positive via self-testing. Females were more likely to test positive for CT/GC when selected to test via self-test versus a clinician test, X(1, N = 3068) = 36.54, p<.01; no significant difference in testing type was observed for males. Overall, 22.5% of students who opted for the self-test option completed the acceptability survey; 63% reported their main reason for testing was unprotected sex. In the past year, 42% reported 4>= partners. The majority were very satisfied and likely to use the service again (82%). CONCLUSIONS: Self testing may be an efficient and effective way to provide STI testing for students, and increase testing uptake. Self-reports of multiple partners, unprotected sex, and detected infections suggest that at-risk students are using the service.

PMID- 29465708 TI - Integration of Contact Tracing and Phylogenetics in an Investigation of Acute HIV Infection. AB - BACKGROUND: The integration of traditional contact tracing with HIV sequence analyses offers opportunities to mitigate some of the barriers to effective network construction. We used combined analyses during an outbreak investigation of spatiotemporally clustered acute HIV infections to evaluate if the observed clustering was the product of a single outbreak. METHODS: We investigated acute and recent HIV index cases reported in North Carolina from 2013 to 2014 and their reported contacts. Contact tracing networks were constructed with surveillance data and compared with phylogenetic transmission clusters involving an index case using available HIV-1 pol sequences including 1672 references. Clusters were defined as clades of 2 or more sequences with a less than 1.5% genetic distance and a bootstrap of at least 98% on maximum-likelihood phylogenies. RESULTS: In total, 68 index cases and 210 contacts (71 HIV infected) were reported. The contact tracing network involved 58 components with low overall density (1.2% statewide); 33% of first-degree contacts could not be located. Among 38 (56%) of 68 index cases and 34 (48%) of 71 contacts with sequences, 13 phylogenetic clusters were identified (size 2-4 members). Four clusters connected network components that were not linked in contact tracing. The largest component (n = 28 cases) included 2 distinct phylogenetic clusters and spanned 2 regions. CONCLUSIONS: We identified the concurrent expansion of multiple small transmission clusters rather than a single outbreak in a largely disconnected contact tracing network. Integration of phylogenetic analyses provided timely information on transmission networks during the investigation. Our findings highlight the potential of combined methods to better identify high-risk networks for intervention. PMID- 29465710 TI - Blood pressure variability increases with advancing chronic kidney disease stage: a cross-sectional analysis of 16 546 hypertensive patients. AB - OBJECTIVE: Increased BP-variability predicts cardiovascular morbidity and mortality in hypertensives. This study aimed to examine short-term BP-variability according to renal function stage. METHODS: We included 16 546 patients [10 270 (62.1%) without/6276 (38.9%) with CKD Stage 1-5] from the Spanish Ambulatory Blood-Pressure Monitoring (ABPM) Registry. Stages of CKD were defined according to K/DIGO criteria, based on estimated glomerular filtration rate calculated with the CKD-EPI equation and albumin-to-creatine ratio. BP-variability was assessed with standard deviation (SD), weighted SD (wSD), coefficient of variation (CV), and average real variability (ARV). RESULTS: Compared with those without CKD, a lower proportion of CKD patients were dippers (51.9 versus 39.6%; P < 0.001). Across CKD stages, a progressive decrease in dipper (from 39.1 to 20.4%; P < 0.001) and increase in riser proportion (from 12.3 to 36.7%; P < 0.001) were noted. Patients with CKD had significantly higher SBP SD, wSD, CV and ARV and lower DBP SD compared with those without CKD (P < 0.001). Within CKD Stages, an increasing trend from Stage 1 towards Stage 5 was observed for SBP SD (from 13.8 +/- 3.7 to 15.6 +/- 5.4 mmHg), wSD (from 12.0 +/- 3.2 to 13.9 +/- 5.1 mmHg), CV (from 10.4 +/- 2.7 to 11.5 +/- 4.1%), ARV (from 9.9 +/- 2.3 to 11.4 +/- 3.2 mmHg); P < 0.001 for all comparisons. DBP SD (P < 0.001), wSD and ARV (P = 0.002) were slightly decreasing, whereas DBP CV increased from Stage 1 to Stage 4 (P < 0.001). In multivariate analysis, male gender, older age, abdominal obesity, diabetes, number of antihypertensive medications, and clinic SBP were independent factors for higher SBP 24-h ARV in CKD. CONCLUSION: An increase in short-term SBP variability was present with advancing CKD stages in a large cohort. This increased SBP-variability may be involved in the sharp elevation of cardiovascular risk with worsening renal function. PMID- 29465711 TI - Relation of blood pressure and organ damage: comparison between feasible, noninvasive central hemodynamic measures and conventional brachial measures. AB - OBJECTIVE: The present cross-sectional study investigated whether central SBP and pulse pressure (PP) measured noninvasively with a novel cuff-based stand-alone monitor are more strongly associated with hypertensive end-organ damage than corresponding brachial measures. METHODS: We investigated the cross-sectional association of central versus brachial SBP and PP with echocardiographic left ventricular mass index (LVMI), LV hypertrophy (LVH), carotid intima-media thickness (IMT), and increased IMT (IMT >= 75th percentile) among 246 participants drawn from the general population (mean age 57.2 years, 55.3% women). RESULTS: All blood pressure (BP) measures were positively correlated with LVMI and IMT (P < 0.001 for all). Brachial and central SBP correlated equally strongly with LVMI (r = 0.42 versus 0.40, P for difference 0.19) and IMT (r = 0.32 versus 0.33, P = 0.60). However, brachial PP correlated more strongly than central PP with LVMI (r = 0.34 versus 0.27, P = 0.03) and IMT (r = 0.40 versus 0.35, P = 0.04). In multivariable-adjusted logistic models, all four BP measures were significantly associated with LVH and increased IMT (P <= 0.03 for all). However, the diagnostic accuracy of logistic regression models that included brachial or central hemodynamic parameters was similar for LVH [area under curve (AUC) for SBP: 0.74 versus 0.76, P = 0.16; AUC for PP: 0.75 versus 0.73, P = 0.35] and IMT (AUC for SBP: 0.61 versus 0.61, P = 0.67; AUC for PP: 0.63 versus 0.61, P = 0.29). CONCLUSION: Our findings suggest that central SBP and PP measured with a stand-alone noninvasive BP monitor do not improve diagnostic accuracy for end-organ damage over corresponding brachial measures. PMID- 29465712 TI - Ambulatory arterial stiffness index as a predictor of blood pressure response to renal denervation. AB - BACKGROUND: Renal denervation (RDN) can reduce blood pressure (BP) in patients with resistant hypertension, but less so in patients with isolated systolic hypertension. A possible explanation is that patients with stiffer arteries may have lesser neural contribution to their hypertension. METHOD: We hypothesized that arterial stiffness predicts the response to RDN. From ambulatory BP monitoring (ABPM), ambulatory arterial stiffness index (AASI) was calculated as 1 - the regression slope of DBP versus SBP. RESULTS: In 111 patients with resistant hypertension, RDN reduced office and 24-h SBP after 3, 6, and 12 months (by -11 +/- 22, -11 +/- 25, -14 +/- 21 mmHg for office, and -4 +/- 11, -5 +/- 12, -5 +/- 15 mmHg for 24-h SBP, respectively, P < 0.01). Patients with baseline AASI above the median (>0.51) showed no change in 24-h SBP at 6 months after RDN (-0.4 +/- 12.3 mmHg, P > 0.05), whereas an AASI below 0.51was associated with a marked reduction (-9.3 +/- 11.0 mmHg, P < 0.01). Across AASI quartiles, patients in the highest quartile (AASI >= 0.60) had lower muscle sympathetic nerve activity than the other three quartiles (39 +/- 13 versus 49 +/- 13 bursts/min, P = 0.035). The responder rate, defined as a 24-h SBP reduction of at least 5% was 58% in the lowest AASI quartile (<0.45) and 16% in the highest quartile (>=0.60). After adjustment for age, sex, BMI, office and 24-h SBP, an AASI less than 0.51predicted those who respond to RDN (odds ratio 3.46, P = 0.04). CONCLUSION: We conclude that in patients with resistant hypertension, a lower AASI is an independent predictor of the BP response to RDN, possibly explained by a more pronounced neurogenic rather than biomechanical contribution to their BP elevation. PMID- 29465713 TI - Hydrochlorothiazide and alternative diuretics versus renin-angiotensin system inhibitors for the regression of left ventricular hypertrophy: a head-to-head meta-analysis. AB - BACKGROUND: Found in 36-41% of hypertension, elevated left ventricular mass (LVM) independently predicts cardiovascular events and total mortality. Conversely, drug-induced regression of LVM predicts improved outcomes. Previous studies have favored renin-angiotensin system inhibitors (RASIs) over other antihypertensives for reducing LVM but ignored differences among thiazide-type diuretics. From evidence regarding potency, cardiovascular events, and electrolytes, we hypothesized a priori that 'CHIP' diuretics [CHlorthalidone, Indapamide and Potassium-sparing Diuretic/hydrochlorothiazide (PSD/HCTZ)] would rival RASIs for reducing LVM. METHOD AND RESULTS: Systematic review yielded 12 relevant double blind randomized trials. CHIPs were more closely associated with reduced LVM than HCTZ (P = 0.004), indicating that RASIs must be compared with each diuretic separately. Publication bias favoring RASIs was corrected by cumulative analysis. For reducing LVM, HCTZ tended to be less effective than RASIs. However, the following surpassed RASIs: chlorthalidone Hedge's G: -0.37 (95% CI -0.72 to 0.02), P = 0.036; indapamide -0.20 (-0.39 to -0.01), P = 0.035; all CHIPs combined (with 61% of patients in one trial) -0.25 (-0.41to -0.09), P = 0.002. Statistical significance (P < 0.05) did not depend on any one trial. CHIPs reduction in LVM was 37% greater than that from RASIs. CHIPs superiority tended to increase with trial duration, from a negligible effect at 0.5 year to a maximal effect at 0.9-1.0 years: -0.26 (-0.43 to -0.09), P = 0.003. Fifty-eight percent of patients had information on echocardiographic components of LVM: relative to RASIs, CHIPs significantly reduced end-diastolic LV internal dimension (EDLVID): -0.18 (-0.36 to -0.00), P = 0.046. Strength of evidence favoring CHIPs over RASIs was at least moderate. CONCLUSION: In these novel results in patients with hypertension, CHIPs surpassed RASIs for reducing LVM and EDLVID. PMID- 29465714 TI - Preeclampsia induced by STOX1 overexpression in mice induces intrauterine growth restriction, abnormal ultrasonography and BOLD MRI signatures. AB - BACKGROUND: Preeclampsia is a major hypertensive disease caused by pregnancy, inducing proteinuria and increased blood pressure starting from the second half of pregnancy (early preeclampsia) or near the end of pregnancy (late preeclampsia). Pre-symptomatic diagnosis would allow for therapeutic interventions, such as with low-dose aspirin. Among non-invasive methods to explore organ physiology, Doppler ultrasonography (US) and functional blood oxygenation level-dependent (BOLD) MRI (which do not need radioactive contrast agents such as gadolinium) can be used in pregnant women. METHODS: In this study, we used US and BOLD MRI to finely characterize the phenotype of preeclampsia induced by the foeto-placental overexpression of the transcription factor storkhead box 1A (STOX1A) in female mice. RESULTS: We could observe late fetal growth restriction consistent with the placental dysfunction revealed by US and the known association between preeclampsia and intra-uterine growth restriction. On US, uterine and umbilical artery as well as heart and kidney parameters were modified in preeclamptic mice. On BOLD MRI, mean T2* values revealed considerable differences between control and preeclamptic placentas, which suggests altered dynamics of oxygen release and ratio of oxyhemoglobin to deoxyhemoglobin in the model. CONCLUSION: These preliminary pre-clinical results suggest that BOLD MRI could be evaluated as a prognostic/diagnostic tool for preeclampsia. PMID- 29465715 TI - Application of strict criteria in adrenal venous sampling increases the proportion of missed patients with unilateral disease who benefit from surgery for primary aldosteronism. AB - OBJECTIVES: Adrenal vein sampling (AVS) is intended to confirm unilateral forms of primary aldosteronism, which are amenable to surgical cure. Excessively strict AVS criteria to define lateralization may result in many patients incorrectly categorized as bilateral primary aldosteronism and opportunity for surgical cure missed. METHODS: Retrospective review of an AVS-primary aldosteronism database in which surgical cases are verified by standardized outcomes. Having used 'less strict' AVS criteria for lateralization, we examined the distribution of AVS lateralization indices in our confirmed unilateral primary aldosteronism cases both with and without cosyntropin stimulation. The proportion of proven unilateral cases that would have been missed with stricter AVS interpretation criteria was calculated. Particular focus was given to the proportion of missed cases according to use of international guidelines. False-positive lateralization with 'less strict' interpretation was also calculated. RESULTS: Of 80 surgical primary aldosteronism cases, 10-23% would have been missed with AVS lateralization indices of 3 : 1 to 5 : 1, with or without cosyntropin. If strict selectivity indices (for confirmation of catheterization) were combined with strict lateralization indices, up to 70% of unilateral primary aldosteronism cases could have been missed. Use of Endocrine Society AVS guidelines would have missed 21-43% of proven unilateral cases. 'Less strict' AVS interpretation yielded one case (1.2%) of false lateralization. CONCLUSION: Excessively strict AVS interpretation criteria will result in a high rate of missed unilateral primary aldosteronism with subsequent loss of opportunity for intervention. Use of more lenient lateralization criteria will improve the detection rate of unilateral primary aldosteronism with very low false-positive rate.

AB - The monitoring of the magnetic field is the most significant process for academic or industrial applications. In this study, we design a self-powered magnetic field sensor based on the magnetorheological elastomer (MRE) and triboelectric nanogenerator (TENG) that can be used for both time-varying and uniform magnetic field (UMF) sensing. This TENG-based magnetic-field sensor (TMFS) relies on contact electrification and electrostatic induction of TENG to generate an electrical signal in response to the magnetic-induced deformation of MRE without using an external power supply. Enabled by the unique sensing mechanism and excellent magnetic-induced deformation of MRE, the TMFS exhibits a fast response (20 ms) and good magnetic-field sensing performance. The TMFS with 60 wt%-MRE shows a maximum sensitivity of 16 mV mT-1 of the magnetic field ranging from 40 to 100 mT experimentally, and the sensitivity and detection range of TMFS can be adjusted by several parameters of the device. Besides the contribution to the effective detection of UMF, this novel sensor provides a new idea for the magnetic-field measurements in self-powered mode.

AB - Cubic, octahedral and rhombic dodecahedral Pd nanocrystals were synthesized and examined as nanocatalysts for electro-oxidation of ethanol and ethylene glycol.

PMID- 29465722 TI - Formation of n-n type heterojunction-based tin organic-inorganic hybrid perovskite composites and their functions in the photocatalytic field. AB - MASnI3/TiO2 composites (MA represents CH3NH3+) are prepared via a solvothermal method and characterized by various techniques. The results indicate that n-n type heterojunction structures and different ohmic contact interfaces are formed for the composites with different contents of MASnI3 and TiO2 before and after calcination, resulting in different optical and photocatalytic performances. Generally speaking, n-n type heterojunctions play roles in photocatalytic applications through two different mechanisms: the heterojunction mechanism and the Z-type mechanism. The calcined composites with better ohmic contact interfaces mainly follow the Z-type mechanism, which can promote direct radiative recombination of photogenerated carriers. As a result, higher luminous intensities and interface recombination instead of bulk recombination between electrons and holes can be achieved, which improves the photoluminescence and photocatalytic activities of the materials. Moreover, the n-n type heterojunction structure avoids p-type defect states to some degree, which averts the hydrolysis and oxidation of MASnI3 in atmosphere and enhances the long-term stability of the MASnI3/TiO2 composites.

AB - DNA switches are ideally suited for numerous nanotechnological applications, and increasing efforts are being directed toward their engineering. In this review, we discuss how to engineer these switches starting from the selection of a specific DNA-based recognition element, to its adaptation and optimisation into a switch, with applications ranging from sensing to drug delivery, smart materials, molecular transporters, logic gates and others. We provide many examples showcasing their high programmability and recent advances towards their real life applications. We conclude with a short perspective on this exciting emerging field. PMID- 29465724 TI - Interaction anisotropy and the KPZ to KPZQ transition in particle deposition at the edges of drying drops. AB - The deposition process at the edge of evaporating colloidal drops varies with the shape of suspended particles. Experiments with prolate ellipsoidal particles suggest that the spatiotemporal properties of the deposit depend strongly on particle aspect ratio. As the aspect ratio increases, the particles form less densely-packed deposits and the statistical behavior of the deposit interface crosses over from the Kardar-Parisi-Zhang (KPZ) universality class to another universality class which was suggested to be consistent with the KPZ plus quenched disorder. Here, we numerically study the effect of particle interaction anisotropy on deposit growth. In essence, we model the ellipsoids, at the interface, as disk-like particles with two types of interaction patches that correspond to specific features at the poles and equator of the ellipsoid. The numerical results corroborate experimental observations and further suggest that the deposition transition can stem from interparticle interaction anisotropy. Possible extensions of our model to other systems are also discussed. PMID- 29465725 TI - O-Difluorodeuteromethylation of phenols using difluorocarbene precursors and deuterium oxide.

This facile method affords a convenient way to introduce OCF2D groups into organic molecules. PMID- 29465726 TI - A Au monolayer on WC(0001) with unexpected high activity towards CO oxidation. AB - Catalysts with weak adsorption yet high reactivity towards CO are urgently required to solve the serious problem of CO poisoning that occurs in many important reactions, e.g., in fuel cells. Using the combination of density functional calculations and ab initio molecular dynamic simulations, we found a promising electrocatalyst for this purpose: a Au monolayer on WC(0001) (AuML/WC), which has both high oxygen reduction activity and high tolerance to CO poisoning. The advantages of using AuML/WC as an electrocatalyst in fuel cells are demonstrated through analyses of energetics of different reaction steps as well as interaction properties of reactants and products. We anticipate that the present results are useful to advance the development of efficient catalysts with high tolerance to CO poisoning.

AB - An AgSCF3 mediated nucleophilic trifluoromethylthiolation reaction for C(sp)-SCF3 bond formation is reported. This nucleophilic trifluoromethylthiolation reaction of bromoalkynones afforded various useful ynonyl trifluoromethyl sulfides in high yields. Interestingly, the over-addition of AgSCF3 is avoided in our approach. PMID- 29465728 TI - A novel class of one-dimensional Ta4TMTe4 (TM = Cr, Fe, Co and Ni) compounds with strain-switched magnetic states. AB - The development of one-dimensional (1D) nanowires with controllable magnetic properties is important for spintronic applications. Herein, we systematically investigated the structural, electronic, and magnetic properties of 1D transition metal (TM) compounds (Ta4TMTe4, TM = Cr, Fe, Co and Ni) through density functional theory (DFT) calculations. Ta4CrTe4 and Ta4FeTe4 are non-magnetic, while Ta4CoTe4 and Ta4NiTe4 are predicted to have antiferromagnetic ground states. Interestingly, uniaxial strain can induce nonmagnetism-ferromagnetism and nonmagnetism-antiferromagnetism transitions in Ta4CrTe4 and Ta4FeTe4 nanowires, respectively. Moreover, the antiferromagnetic ground states in Ta4CoTe4 and Ta4NiTe4 can be switched to ferromagnetic states through moderate strain. These strain-dependent magnetic moment and magnetic coupling transitions are related to the redistribution of d states in TM atoms. Our findings suggest a new route for facilitating the design of nanoelectronics and spintronics. PMID- 29465729 TI - Ballistic impact response of lipid membranes. AB - Therapeutic agent loaded micro and nanoscale particles as high-velocity projectiles can penetrate cells and tissues, thereby serving as gene and drug delivery vehicles for direct and rapid internalization. Despite recent progress in developing micro/nanoscale ballistic tools, the underlying biophysics of how fast projectiles deform and penetrate cell membranes is still poorly understood. To understand the rate and size-dependent penetration processes, we present coarse-grained molecular dynamics simulations of the ballistic impact of spherical projectiles on lipid membranes. Our simulations reveal that upon impact, the projectile can pursue one of three distinct pathways. At low velocities below the critical penetration velocity, projectiles rebound off the surface. At intermediate velocities, penetration occurs after the projectile deforms the membrane into a tubular thread. At very high velocities, rapid penetration occurs through localized membrane deformation without tubulation. Membrane tension, projectile velocity and size govern which phenomenon occurs, owing to their positive correlation with the reaction force generated between the projectile and the membrane during impact. Two critical membrane tension values dictate the boundaries among the three pathways for a given system, due to the rate dependence of the stress generated in the membrane. Our findings provide broad physical insights into the ballistic impact response of soft viscous membranes and guide design strategies for drug delivery through lipid membranes using micro/nanoscale ballistic tools.

PMID- 29465730 TI - Dihomo-gamma-linolenic acid induces fat loss in C. elegans in an omega-3 independent manner by promoting peroxisomal fatty acid beta-oxidation. AB - Bioactive compounds, including some fatty acids (FAs), can induce beneficial effects on body fat-content and metabolism. In this work, we have used C. elegans as a model to examine the effects of several FAs on body fat accumulation. Both omega-3 and omega-6 fatty acids induced a reduction of fat content in C. elegans, with linoleic, gamma-linolenic and dihomo-gamma-linolenic acids being the most effective ones. These three FAs are sequential metabolites especially in omega-6 PUFA synthesis pathway and the effects seem to be primarily due to dihomo-gamma linolenic acid, and independent of its transformation into omega-3 or arachidonic acid. Gene expression analyses suggest that peroxisomal beta oxidation is the main mechanism involved in the observed effect. These results point out the importance of further analysis of the activity of these omega-6 FAs, due to their potential application in obesity and related diseases. PMID- 29465734 TI - Refining the aggregate exposure pathway. AB - Advancements in measurement technologies and modeling capabilities continue to result in an abundance of exposure information, adding to that currently in existence. However, fragmentation within the exposure science community acts as an obstacle for realizing the vision set forth in the National Research Council's report on Exposure Science in the 21st century to consider exposures from source to dose, on multiple levels of integration, and to multiple stressors. The concept of an Aggregate Exposure Pathway (AEP) was proposed as a framework for organizing and integrating diverse exposure information that exists across numerous repositories and among multiple scientific fields. A workshop held in May 2016 followed introduction of the AEP concept, allowing members of the exposure science community to provide extensive evaluation and feedback regarding the framework's structure, key components, and applications. The current work briefly introduces topics discussed at the workshop and attempts to address key challenges involved in refining this framework. The resulting evolution in the AEP framework's features allows for facilitating acquisition, integration, organization, and transparent application and communication of exposure knowledge in a manner that is independent of its ultimate use, thereby enabling reuse of such information in many applications.

AB - A reductive dicarbofunctionalization reaction of alkenes has been developed and applied to the preparation of substituted carbo- and heterocycles.

PMID- 29465736 TI - Fermentation of non-digestible raffinose family oligosaccharides and galactomannans by probiotics. AB - Due to their prebiotic potential indigestible oligosaccharides became a major focus of research interest. In this study the growth of selected probiotic strains including lactobacilli, bifidobacteria, Lactococcus lactis, Streptococcus salivarius ssp. thermophilus, Pediococcus ssp. and Enterococcus faecium with the, raffinose family oligosaccharides (RFOs) raffinose, stachyose and verbascose and galactomannan from guar bean Cyamopsis tetragonoloba (total guar carbohydrates, oligosaccharides (dp 2-4) and polysaccharides (dp > 5), obtained by size exclusion chromatography) were tested by means of turbidity measurements. RFOs were used by 75% of all strains, with some delay for the trisaccharide raffinose and the tetrasaccharide stachyose and a limited fermentation of the pentasaccharide verbascose. L. reuteri, P. pentosaceus and B. lactis HNO19TM were able to ferment not only raffinose and stachyose but also verbascose. Guar oligosaccharides were fermented by 15 out of 20 strains; P. acidilactici, L. acidophilus, L. rhamnosus GG and B. animalis ssp. lactis BB12 metabolized them comparably well as glucose or galactose. Isolated guar polysaccharides were not fermented whereas total guar carbohydrates were fermented by 7 strains, apparently caused by the oligosaccharide content. The findings of this study may be important for functional food products especially for indigestible oligosaccharides which may cause adverse effects in the gut when not cleaved. PMID- 29465737 TI - A novel panchromatic shutter based on an ambipolar electrochromic system without supporting electrolyte. AB - Two triphenylamine derivatives, N,N,N',N'-tetrakis(4-methoxyphenyl)-1,4 phenylenediamine TPPA and N,N,N',N'-tetrakis(4-methoxyphenyl)-1,1'-biphenyl-4,4' diamine TPB, were successfully prepared and combined with HV to fabricate the electrochromic device as a panchromatic shutter for the application of transparent display. The obtained electrochromic device exhibits exceptional novel electrochromic properties, including enhanced color contrast, switching time, and long-term stability. Furthermore, it is worth mentioning that the most important contribution of this ambipolar system approach is that no supporting electrolyte is added into the device. PMID- 29465738 TI - Positional accuracy of geocoding from residential postal codes versus full street addresses. AB - BACKGROUND: Postal codes are often the only geographic identifier available for assigning contextual or environmental information to a study population. This analysis assesses the influence of three factors-delivery mode type (mode of postal delivery), representative point type (source of latitude-longitude coordinates), and community size-on the accuracy of postal code spatial assignment. DATA AND METHODS: PCCF+ (Postal Code Conversion File Plus) was used to assign delivery mode type, representative point type and community size to each individual in the 2011 Census of Canada. A sample (n = 1,004) was randomly selected with a minimum of 90 observations for each category of those three factors. Based on the address information of individuals in the sample, measures of positional accuracy for geocoding from residential postal codes (PCCF+) versus reference locations as determined by full street addresses (Google Maps) were calculated using a geographic information system. Accuracy was measured as the distance that the geocoded position differed from the full street address. RESULTS: Positional accuracy was related primarily to mode of postal delivery. Rural and mixed (partly urban, partly rural) modes had much higher geocoding error than did urban modes. Rural and small-town Canada and latitude and longitude based on dissemination area centroids had low accuracy, largely because of their close relationship to rural and mixed modes of delivery. DISCUSSION: The accuracy of geocoding from postal codes can vary. Geocoding imprecision may result in misclassification, depending on the spatial resolution of the environmental or contextual measures. The spatial resolution required for a study helps to identify subpopulations that should be excluded because of inadequate positional accuracy. PMID- 29465739 TI - Analysis of trends in the prevalence of cannabis use in Canada, 1985 to 2015. AB - BACKGROUND: The Canadian federal government has committed to legalize, regulate, and restrict non-medical cannabis use by adults in 2018. To prepare for monitoring the health, social and economic impacts of this policy change, a greater understanding of the long-term trends in the prevalence of cannabis use in Canada is needed. DATA AND METHODS: Nine national surveys of the household population collected information about cannabis use during the period from 1985 through 2015. These surveys are examined for comparability. The data are used to estimate past-year (current) cannabis use (total, and by sex and age). Based on the most comparable data, trends in use from 2004 through 2015 are estimated. RESULTS: From 1985 through 2015, past-year cannabis use increased overall. Analysis of comparable data from the Canadian Tobacco Use Monitoring Survey and the Canadian Tobacco, Alcohol and Drugs Survey for the 2004-to-2015 period suggests that use was stable among 15- to 17-year-old males, decreased among 15- to 17-year-old females and among 18- to 24-year-olds (both sexes), and increased among people aged 25 or older. DISCUSSION: According to data from national population surveys, since 2004, cannabis use was stable or decreased among youth, and rose among adults. Results highlight the importance of consistent monitoring of use in the pre-and post-legalization periods. PMID- 29465740 TI - A Technical Guide for Fiber Tract Dissection of the Internal Capsule. AB - AIM: Dissection of white fibers is important in identifying detailed neuroanatomical relationships. With tractrography it is possible to transport and apply this knowledge in a practical way to treat many diseases involving the white matter. MATERIAL AND METHODS: The Klingler method, subsequently disseminated by Ture with slight modifications was used. RESULTS: We review some historical aspects of white fibers and provide a guide for dissection of the internal capsule. The removal of gray matter allowed us to obtain a view of the white matter. We removed all U-shaped fibers to expose the insular cortex. The cortex of the insular lobe was removed, which exposed the extreme capsule. The removal of the claustrum exposed the external capsule, which covers the lentiform nucleus, specifically the putamen. During dissection, removing some fibers of the external capsule produced windows in which the putamen could be medially visualized. Since the internal capsule lies medial to the lentiform nucleus, it was necessary to remove the nucleus in order to expose the internal capsule. We identified five regions of the internal capsule: the anterior limb, genu, posterior limb, and sublenticular and retrolenticular parts. Finally, we determined that the fibers of the corona radiata condense into the internal capsule at the level of the superior border of the lentiform nucleus. CONCLUSION: Knowledge gained with the cadaveric fiber dissection technique can be applied in microsurgical practice and can be used to evaluate the surgical treatment for different tumors and vascular malformations. PMID- 29465741 TI - Management of Hardware Related Infections after DBS Surgery: A Cost Analysis. AB - AIM: To investigate the costs of treating the infection with antibiotics only with the risk of surgery when unsuccessful versus immediate removal followed by re-implantation in patients with deep brain stimulation (DBS) hardware infection. MATERIAL AND METHODS: We calculated the costs of the different strategies through a standard costing procedure. A decision model has been applied to establish the average treatment cost per patient representative for a clinical setting where both strategies are employed. Subsequently, a sensitivity analysis has been performed to assess the influence of clinical assumptions regarding the effectiveness of antibiotics treatment on average treatment costs. RESULTS: The costs of treating a case of DBS hardware infection with immediate internal pulse generator (IPG) replacement surgery were ?29,301 compared to ?9499 for successful antibiotic treatment. For antibiotic treatment followed by IPG replacement surgery the total costs were ?38,741. Antibiotic treatment alone was successful in 44% (4/9) of the included cases of DBS infection, resulting in average treatment costs per patient of ?25,745. Trying to resolve DBS hardware infections initially with antibiotics reduced treatment costs by 12.1%. CONCLUSION: Treatment with antibiotics with the risk of a later removal when unsuccessful was a more valuable strategy in terms of costs when compared to immediate surgical intervention in cases of hardware-related infections in DBS surgeries.

AB - Objective Restoration of CSF flow and removal of Intraventricular Cystecercal Cyst is the main goal in treatment Hydrocephalus due Intraventricular Neurocysticercosis. The purpose of this study was to evaluate the technique and outcome of Endoscopic management of Intraventricular Neurocysticercosis. Methods We retrospectively analysed the records of 30 consecutive patients of Intraventricular Intra third and fourth ventricle Neurocysticercosiswho underwent endoscopic management.The clinical profile of the patient were evaluated which included age, symptoms and signs. Transcranial endoscopy was perfomed through frontal burr hole using Gaab Universal Endoscope system with rigid 0o and 30o telescope for ETV and removal of cyst was described. The mean follow up was 22.6 months Results In 86.67 % (26/30) patients we are able to visualize/ excise/ decompress the cyst. We were able to successfully excise all the third ventricular cysts (16/16) and in 66.67% (8/12) of the fourth ventricular cysts.In 90% (27/30) patients we were able to successfully divert the CSF flow and achieve long term shunt free period. Conclusion We found that endoscopic CSF diversion in cases of Intraventricular NCC is feasible and associated with high success rate. Endoscopic CSF diversion in NCC related hydrocephalus usually produces a long term cure. PMID- 29465743 TI - Participation in bowel screening among men attending abdominal aortic aneurysm screening. AB - BACKGROUND: Uptake of population-based screening for colorectal cancer in Scotland is around 55 per cent. Abdominal aortic aneurysm (AAA) screening has recently been introduced for men aged 65 years and the reported uptake is 78 per cent. The aim was to determine the impact of a brief intervention on bowel screening in men who attended AAA screening, but previously failed to complete bowel screening. METHODS: Men invited for AAA screening between September 2015 and March 2016 within NHS Tayside were included. Attendees who had not responded to their latest bowel screening invitation were seen by a colorectal cancer clinical nurse specialist. Reasons for not completing the faecal occult blood test (FOBT) were recorded; brief information on colorectal cancer screening was communicated, and participants were offered a further invitation to complete a FOBT. Those who responded positively were sent a further FOBT from the Scottish Bowel Screening Centre. Subsequent return of a completed FOBT within 6 months was recorded. RESULTS: A total of 556 men were invited for AAA screening, of whom 38.1 per cent had not completed a recent FOBT. The primary reason stated for not participating was the time taken to complete the test or forgetting it (35.1 per cent). Other reasons included: lack of motivation (23.4 per cent), confusion regarding the aim of screening (16.2 per cent), disgust (19.8 per cent), fear (6.3 per cent) and other health problems (9.9 per cent). Following discussion, 81.1 per cent agreed to complete the FOBT and 49 per cent subsequently returned the test. CONCLUSION: A substantial proportion of previous bowel screening non responders subsequently returned a completed FOBT following a brief intervention with a nurse specialist. Attendance at non-bowel screening appointments may provide a valuable opportunity to improve bowel screening uptake. PMID- 29465744 TI - Baseline factors predicting a response to neoadjuvant chemotherapy with implications for non-surgical management of triple-negative breast cancer. AB - BACKGROUND: Patients with triple-negative breast cancer (TNBC) and a pathological complete response (pCR) after neoadjuvant chemotherapy may be suitable for non surgical management. The goal of this study was to identify baseline clinicopathological variables that are associated with residual disease, and to evaluate the effect of neoadjuvant chemotherapy on both the invasive and ductal carcinoma in situ (DCIS) components in TNBC. METHODS: Patients with TNBC treated with neoadjuvant chemotherapy followed by surgical resection were identified. Patients with a pCR were compared with those who had residual disease in the breast and/or lymph nodes. Clinicopathological variables were analysed to determine their association with residual disease. RESULTS: Of the 328 patients, 36.9 per cent had no residual disease and 9.1 per cent had residual DCIS only. Patients with residual disease were more likely to have malignant microcalcifications (P = 0.023) and DCIS on the initial core needle biopsy (CNB) (P = 0.030). Variables independently associated with residual disease included: DCIS on CNB (odds ratio (OR) 2.46; P = 0.022), T2 disease (OR 2.40; P = 0.029), N1 status (OR 2.03; P = 0.030) and low Ki-67 (OR 2.41; P = 0.083). Imaging after neoadjuvant chemotherapy had an accuracy of 71.7 (95 per cent c.i. 66.3 to 76.6) per cent and a negative predictive value of 76.9 (60.7 to 88.9) per cent for identifying residual disease in the breast and lymph nodes. Neoadjuvant chemotherapy did not eradicate the DCIS component in 55 per cent of patients. CONCLUSION: The presence of microcalcifications on imaging and DCIS on initial CNB are associated with residual disease after neoadjuvant chemotherapy in TNBC. These variables can aid in identifying patients with TNBC suitable for inclusion in trials evaluating non-surgical management after neoadjuvant chemotherapy. PMID- 29465745 TI - Deserving citizenship? Exploring migrants' experiences of the 'citizenship test' process in the United Kingdom. AB - Since the early 2000s several European countries have introduced language and citizenship tests as new requirements for access to long-term residence or naturalization. The content of citizenship tests has been often presented as exclusionary in nature, in particular as it is based on the idea that access to citizenship has to be 'deserved'. In this paper, we aim to explore the citizenship tests 'from below', through the focus on the experience of migrants who prepare and take the 'Life in the UK' test, and with particular reference to how they relate to the idea of 'deservingness'. Through a set of in-depth interviews with migrants in two different cities (Leicester and London), we show that many of them use narratives in which they distinguish between the 'deserving citizens' and the 'undeserving Others' when they reflect upon their experience of becoming citizens. In so doing, they negotiate new hierarchies of inclusion into and exclusion from citizenship, which reflect broader neo-liberal and ethos-based conceptions of citizenship.

AB - BACKGROUND: Textbook outcome is a multidimensional measure representing an ideal course after oesophagogastric cancer surgery. It comprises ten perioperative quality-of-care parameters and has been developed recently using population-based data. Its association with long-term outcome is unknown. The objectives of this study were to validate the clinical relevance of textbook outcome at a hospital level, and to assess its relation with long-term survival after treatment for oesophagogastric cancer. METHODS: All patients with oesophageal or gastric cancer scheduled for surgery with curative intent between January 2009 and June 2015 were selected from an institutional database. A Cox model was used to study the association between textbook outcome and survival. RESULTS: A textbook outcome was achieved in 58 of 144 patients (40.3 per cent) with oesophageal cancer and in 48 of 105 (45.7 per cent) with gastric cancer. Factors associated with not achieving a textbook outcome were failure to achieve a lymph node yield of at least 15 (after oesophagectomy) and postoperative complications of grade II or more. After oesophagectomy, median overall survival was longer for patients with a textbook outcome than for patients without (median not reached versus 33 months; P = 0.012). After gastrectomy, median survival was 54 versus 33 months respectively (P = 0.018). In multivariable analysis, textbook outcome was associated with overall survival after oesophagectomy (hazard ratio 2.38, 95 per cent c.i. 1.29 to 4.42) and gastrectomy (hazard ratio 2.58, 1.25 to 5.32). CONCLUSION: Textbook outcome is a clinically relevant measure in patients undergoing oesophagogastric cancer surgery as it can identify underperforming parameters in a hospital setting. Overall survival in patients with a textbook outcome is better than in patients without a textbook outcome. PMID- 29465747 TI - Antibiotics for treating gonorrhoea in pregnancy. AB - BACKGROUND: Gonorrhoea is a sexually transmitted infection that is caused by Neisseria gonorrhoeae, and is a major public health challenge today. N gonorrhoeae can be transmitted from the mother's genital tract to the newborn during birth, and can cause gonococcal ophthalmia neonatorum as well as systemic neonatal infections. It can also cause endometritis and pelvic sepsis in the mother. This review updates and replaces an earlier Cochrane Review on antibiotics for treating this infectious condition. OBJECTIVES: To assess the clinical effectiveness and harms of antibiotics for treating gonorrhoea in pregnant women. SEARCH METHODS: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 May 2017), LILACS database (1982 to April 5, 2017), the WHO International Clinical Trials Registry Platform (ICTRP; April 5, 2017), ClinicalTrials.gov (April 5, 2017), the ISRCTN Registry (April 5, 2017), and Epistemonikos (April 5, 2017). We also searched reference lists of all retrieved articles. SELECTION CRITERIA: We included randomised controlled trials (RCTs) comparing the use of antibiotics for treating gonorrhoea in pregnancy. The antibiotics could have been used alone or in combination, were administered parenterally, orally, or both, and were compared with another antibiotic.We included RCTs regardless of their publication status (published, unpublished, published as an article, an abstract, or a letter), language, or country. We applied no limits on the length of follow-up.We excluded RCTs using a cluster- or cross-over design, or quasi-RCTs. DATA COLLECTION AND ANALYSIS: Three review authors independently assessed trials for inclusion and risk of bias, extracted data, and checked them for accuracy. MAIN RESULTS: We included two RCTs, that randomised 514 pregnant women (347 women analysed) at a mean gestational age of 22 weeks. Both trials were conducted in the outpatient department of the same two hospitals in the USA between 1993 and 2001, and had a follow-up of 14 days. One of the trials was sponsored by a drug company. We considered both trials to be at a high risk of bias.One trial compared ceftriaxone (125 mg, intramuscular) with cefixime (400 mg, oral); the other trial had three arms, and assessed ceftriaxone (250 mg, intramuscular) versus either amoxicillin (3 g, oral) plus probenecid (1 g, oral) or spectinomycin (2 g, intramuscular). We did not include the spectinomycin data because this medication is no longer produced. We were unable to conduct meta-analysis because the trials compared different medications.We found inconclusive evidence that there were clear differences in the cure of gonococcal infections (genital, extragenital, or both) between intramuscular ceftriaxone versus oral amoxicillin plus oral probenecid (risk ratio (RR) 1.07, 95% confidence interval (CI) 0.98 to 1.16; one RCT; 168 women; very low-quality evidence) or intramuscular ceftriaxone versus oral cefixime (RR 0.99, 95% CI 0.91 to 1.08; one RCT; 95 women; very low-quality evidence).Neither of the trials reported on two of this review's primary maternal outcomes: incidence of obstetric complications (miscarriage, premature rupture of membranes, preterm delivery, or fetal death), or disseminated gonococcal infection, or on the incidence of neonatorum ophthalmia in the neonates.One trial reported one case of vomiting in the oral amoxacillin plus probenecid group. Trials reported pain at the injection sites, but did not quantify it. Hyperberbilurrubinemia was more frequent in neonates whose mothers were exposed to ceftriaxone. There were no clear differences between groups for neonatal malformation. AUTHORS' CONCLUSIONS: This Cochrane Review found high levels of cure of gonococcal infections in pregnancy with the given antibiotic regimens. However, the evidence in this review is inconclusive as it does not support one particular regimen over another. This conclusion was based on very low-quality evidence (downgraded for poor trial design, imprecision) from two trials (involving 514 women), which we assessed to be at a high risk of bias for a number of domains. The harm profiles of the antibiotic regimes featured in this review remain unknown.High-quality RCTs are needed, with sufficient power to assess the clinical effectiveness and potential harms of antibiotics in pregnant women with gonorrhoea. These should be planned according to Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT),conducted following CONSORT recommendations, and based on Patient Centered Outcomes Research Institute (PCORI) outcomes. PMID- 29465748 TI - Species associations overwhelm abiotic conditions to dictate the structure and function of wood-decay fungal communities. AB - Environmental conditions exert strong controls on the activity of saprotrophic microbes, yet abiotic factors often fail to adequately predict wood decomposition rates across broad spatial scales. Given that species interactions can have significant positive and negative effects on wood-decay fungal activity, one possibility is that biotic processes serve as the primary controls on community function, with abiotic controls emerging only after species associations are accounted for. Here we explore this hypothesis in a factorial field warming- and nitrogen-addition experiment by examining relationships among wood decomposition rates, fungal activity, and fungal community structure. We show that functional outcomes and community structure are largely unrelated to abiotic conditions, with microsite and plot-level abiotic variables explaining at most 19% of the total variability in decomposition and fungal activity, and 2% of the variability in richness and evenness. In contrast, taxonomic richness, evenness, and species associations (i.e., co-occurrence patterns) exhibited strong relationships with community function, accounting for 52% of the variation in decomposition rates and 73% in fungal activity. A greater proportion of positive vs. negative species associations in a community was linked to strong declines in decomposition rates and richness. Evenness emerged as a key mediator between richness and function, with highly even communities exhibiting a positive richness-function relationship and uneven communities exhibiting a negative or null response. These results suggest that community-assembly processes and species interactions are important controls on the function of wood-decay fungal communities, ultimately overwhelming substantial differences in abiotic conditions. PMID- 29465750 TI - Identification of pyrG Used as an Endogenous Reference Gene in Qualitative and Real-Time Quantitative PCR Detection of Pleurotus ostreatus. AB - : As a well-known edible fungus rich in nutrients, Pleurotus ostreatus has been used as an alternative to expensive wild edible fungi. Specifically, the fact that using P. ostreatus instead of other expensive wild edible fungi has damaged the rights and interests of consumers. Among the existing methods for detection of food adulteration, the amplification of endogenous reference gene is the most accurate method. However, an ideal endogenous reference gene for P. ostreatus has yet to be developed. In this study, a DNA extraction method for P. ostreatus was optimized, and pyrG was selected as a species-specific gene through sequence alignment. This gene was subsequently subjected to qualitative and quantitative Polymerase Chain Reaction (PCR) assays with 3 different P. ostreatus varieties and 7 other species. A low detection limit of 5 pg/MUL was obtained by TaqMan quantitative PCR, and no pyrG amplification product was observed in the 7 other species. No allelic variation was detected in P. ostreatus varieties. These experiments confirmed that pyrG was an ideal endogenous reference gene for the qualitative and real-time quantitative PCR detection of P. ostreatus. This method was also suitable for the examination of processed P. ostreatus samples and determination of adulteration in wild mushrooms. PRACTICAL APPLICATION: The pyrG gene was chosen as an ideal endogenous reference gene for the qualitative and real-time quantitative PCR detection of P. ostreatus, and the detection limit was 5 pg/MUL for the quantification. This method is used not only for raw materials but also for processed P. ostreatus products and other processed mushroom foods. PMID- 29465749 TI - Systematic review of measurement tools to assess surgeons' intraoperative cognitive workload. AB - BACKGROUND: Surgeons in the operating theatre deal constantly with high-demand tasks that require simultaneous processing of a large amount of information. In certain situations, high cognitive load occurs, which may impact negatively on a surgeon's performance. This systematic review aims to provide a comprehensive understanding of the different methods used to assess surgeons' cognitive load, and a critique of the reliability and validity of current assessment metrics. METHODS: A search strategy encompassing MEDLINE, Embase, Web of Science, PsycINFO, ACM Digital Library, IEEE Xplore, PROSPERO and the Cochrane database was developed to identify peer-reviewed articles published from inception to November 2016. Quality was assessed by using the Medical Education Research Study Quality Instrument (MERSQI). A summary table was created to describe study design, setting, specialty, participants, cognitive load measures and MERSQI score. RESULTS: Of 391 articles retrieved, 84 met the inclusion criteria, totalling 2053 unique participants. Most studies were carried out in a simulated setting (59 studies, 70 per cent). Sixty studies (71 per cent) used self reporting methods, of which the NASA Task Load Index (NASA-TLX) was the most commonly applied tool (44 studies, 52 per cent). Heart rate variability analysis was the most used real-time method (11 studies, 13 per cent). CONCLUSION: Self report instruments are valuable when the aim is to assess the overall cognitive load in different surgical procedures and assess learning curves within competence-based surgical education. When the aim is to assess cognitive load related to specific operative stages, real-time tools should be used, as they allow capture of cognitive load fluctuation. A combination of both subjective and objective methods might provide optimal measurement of surgeons' cognition. PMID- 29465751 TI - Prognostic value of pathological lymph node status and primary tumour regression grading following neoadjuvant chemotherapy - results from the MRC OE02 oesophageal cancer trial. AB - AIMS: Neoadjuvant chemotherapy (NAC) remains an important therapeutic option for advanced oesophageal cancer (OC). Pathological tumour regression grade (TRG) may offer additional information by directing adjuvant treatment and/or follow-up but its clinical value remains unclear. We analysed the prognostic value of TRG and associated pathological factors in OC patients enrolled in the Medical Research Council (MRC) OE02 trial. METHODS AND RESULTS: Histopathology was reviewed in 497 resections from OE02 trial participants randomised to surgery (S group; n = 244) or NAC followed by surgery [chemotherapy plus surgery (CS) group; n = 253]. The association between TRG groups [responders (TRG1-3) versus non-responders (TRG4 5)], pathological lymph node (LN) status and overall survival (OS) was analysed. One hundred and ninety-five of 253 (77%) CS patients were classified as 'non responders', with a significantly higher mortality risk compared to responders [hazard ratio (HR) = 1.53, 95% confidence interval (CI) = 1.05-2.24, P = 0.026]. OS was significantly better in patients without LN metastases irrespective of TRG [non-responders HR = 1.87, 95% CI = 1.33-2.63, P < 0.001 versus responders HR = 2.21, 95% CI = 1.11-4.10, P = 0.024]. In multivariate analyses, LN status was the only independent factor predictive of OS in CS patients (HR = 1.93, 95% CI = 1.42 2.62, P < 0.001). Exploratory subgroup analyses excluding radiotherapy-exposed patients (n = 48) showed similar prognostic outcomes. CONCLUSION: Lymph node status post-NAC is the most important prognostic factor in patients with resectable oesophageal cancer, irrespective of TRG. Potential clinical implications, e.g. adjuvant treatment or intensified follow-up, reinforce the importance of LN dissection for staging and prognostication. PMID- 29465752 TI - Endothelial extracellular vesicles modulate the macrophage phenotype: Potential implications in atherosclerosis. AB - Endothelial cells (ECs) and macrophages engage in tight and specific interactions that play critical roles in cardiovascular homeostasis and the pathogenesis of atherosclerosis. Extracellular vesicles (EVs) are circular membrane fragments released from the endosomal compartment as exosomes or shed from the surfaces of the membranes of most cell types. Increasing evidence indicates that EVs play a pivotal role in cell-to-cell communication. However, the contribution of EVs, as determine by oxidized low-density lipoprotein (ox-LDL)-exposed and/or Kruppel like factor 2 (KLF2)-transduced ECs in the interaction between vascular ECs and monocytes/macrophages, which is a key event in atherosclerotic plaque development, has remained elusive. This study demonstrates the characteristic impact of EVs from ox-LDL-treated and/or KLF2-transduced ECs on the monocyte/macrophage phenotype in vitro and in vivo.Q-PCR showed that both the atherosclerosis inducer ox-LDL and atheroprotective factor KLF2 regulated inflammation-associated microRNA-155 (miR-155) expression in human umbilical vein endothelial cells (HUVECs). Moreover, coculture, immunofluorescence and flow cytometry revealed that miR-155 was enriched in ox-LDL-induced ECs-EVs and subsequently transferred to human monocytic THP1 cells, in which these vesicles enhance monocyte activation by shifting the monocytes/macrophages balance from anti-inflammatory M2 macrophages towards proinflammatory M1 macrophages; EVs from KLF2-expressing ECs suppressed monocyte activation by enhancing immunomodulatory responses and diminishing proinflammatory responses, which indicate the potent anti-inflammatory activities of these cells. Furthermore, oil red staining showed that atherosclerotic lesions were reduced in mice that received EVs from KLF2 transduced ECs with decreased proinflammatory M1 macrophages and increased anti inflammatory M2 macrophages, and this effect is at least partly due to the decreased expression of inflammation-associated miR-155, confirming our in vitro findings. In summary, this study provides novel insights into the pathophysiological effects of altered EV secretion and/or microRNA content and their influence on modulating monocyte activation depending on the environment surrounding EVs-releasing ECs. PMID- 29465753 TI - Size and molecular weight determination of polysaccharides by means of nano electrospray gas-phase electrophoretic mobility molecular analysis (nES GEMMA). AB - Size, size distribution and molecular weight (MW) determination of nanoparticles and that are for example large polymers, are of great interest and pose an analytical challenge. In this context, nano electrospray gas-phase electrophoretic mobility molecular analysis (nES GEMMA) is a valuable tool with growing impact. Separation of single-charged analytes according to their electrophoretic mobility diameter (EMD) starting from single-digit EMDs up to several hundred nm diameters is possible. In case of spherical analytes, the EMD corresponds to the dry nanoparticle size. Additionally, the instrument is capable of number-based, single-particle detection following the recommendation of the European Commission for nanoparticle characterization (2011/696/EU). In case an EMD/MW correlation for a particular compound class (based on availability of well defined standards) exists, a nanoparticle's MW can be determined from its EMD. In the present study, we focused on nES GEMMA of linear and branched, water-soluble polysaccharides forming nanoparticles and were able to obtain spectra for both analyte classes regarding single-charged species. Based on EMDs for corresponding analytes, an excellent EMD/MW correlation could be obtained in case of the branched natural polymer (dextran). This enables the determination of dextran MWs from nES GEMMA spectra despite high analyte polydispersity and in a size/MW range, where classical mass spectrometry is limited. EMD/MW correlations based on linear (pullulans, oat-beta-glucans) polymers were significantly different, possibly indicating challenges in the exact MW determination of these compounds by, for example, chromatographic and light scattering means. Despite these observations, nES GEMMA of linear, monosaccharide-based polymers enabled the determination of size and size-distribution of such dry bionanoparticles. PMID- 29465755 TI - Comparison of the CMNC and MNC apheresis protocol for the collection of T-cells showed comparable outcome: An observational study in a single centre. AB - BACKGROUND: An increasing demand for human lymphocytes require an efficient, reliable and reproducible lymphocyte process. Here, we compare the Spectra Optia(r) CMNC protocol with the Optia MNC platform in unmobilised donor lymphocyte collections. PURPOSE: To establish and compare the feasibility, efficiency, and practicability of the two apheresis protocols. METHODS: Data was collected prospectively from 60 non-cytokine stimulate donors who underwent a total of 64 T-cell collection procedures. Of these, 24 procedures were performed in the CMNC cohort and 40 procedures in the MNC cohort. All donors in the CMNC group were related; all donors in the MNC group were donors from a registry. Donor characteristics, procedure parameters and cellular product content were analysed and compared. RESULTS: Donor characteristics and full blood count results were comparable, except the median white blood cell count, which was higher in the CMNC cohort (6.87 vs. 5.58 *109 /L, P < .005). This resulted in higher lymphocyte (1.95 vs. 1.57 *109 /L, P < .009) and CD3+ cell counts (1476 vs. 1060/L, P < .02). A total blood volume processed of 2.0 resulted in i) run time (222 vs. 242 min), ii) product volume (192 vs. 183 ml), iii) platelet content (2140 vs. 1345 *106 /ml, P < .003). CD3+ CE2 (%): 54.7 vs. 50.4. CONCLUSION: The CMNC and MNC protocols are reliable, efficient and comparable in performance parameters and cell composition of final product, respectively. One advantages of the CMNC protocol is the potential ability to tailor the cell composition of the final product accordingly to demands from cell processing laboratories. PMID- 29465756 TI - A Variety of Bond Analysis Methods, One Answer? An Investigation of the Element Oxygen Bond of Hydroxides Hn XOH. AB - There is a great variety of bond analysis tools that aim to extract information on the bonding situation from the molecular wavefunction. Because none of these can fully describe bonding in all of its complexity, it is necessary to regard a balanced selection of complementary analysis methods to obtain a reliable chemical conclusion. This is, however, not a feasible approach in most studies because it is a time-consuming procedure. Therefore, we provide the first comprehensive comparison of modern bonding analysis methods to reveal their informative value. The element-oxygen bond of neutral Hn XOH model compounds (X=Li, Be, B, C, N, O, F, Na, Mg, Al, Si, P, S, Cl) is investigated with a selection of different bond analysis tools, which may be assigned into three different categories: i) real space bonding indicators (quantum theory of atoms in molecules (QTAIM), the electron localizability indicator (ELI-D), and the Raub Jansen index), ii) orbital-based descriptors (natural bond orbitals (NBO), natural resonance theory (NRT), and valence bond (VB) calculations), and iii) energy analysis methods (energy decomposition analysis (EDA) and the Q-analysis). Besides gaining a deep insight into the nature of the element-oxygen bond across the periodic table, this systematic investigation allows us to get an impression on how well these tools complement each other. Ionic, highly polarized, polarized covalent, and charge-shift bonds are discerned from each other. PMID- 29465754 TI - Core cis-element variation confers subgenome-biased expression of a transcription factor that functions in cotton fiber elongation. AB - Cotton cultivars have evolved to produce extensive, long, seed-born fibers important for the textile industry, but we know little about the molecular mechanism underlying spinnable fiber formation. Here, we report how PACLOBUTRAZOL RESISTANCE 1 (PRE1) in cotton, which encodes a basic helix-loop-helix (bHLH) transcription factor, is a target gene of spinnable fiber evolution. Differential expression of homoeologous genes in polyploids is thought to be important to plant adaptation and novel phenotypes. PRE1 expression is specific to cotton fiber cells, upregulated during their rapid elongation stage and A-homoeologous biased in allotetraploid cultivars. Transgenic studies demonstrated that PRE1 is a positive regulator of fiber elongation. We determined that the natural variation of the canonical TATA-box, a regulatory element commonly found in many eukaryotic core promoters, is necessary for subgenome-biased PRE1 expression, representing a mechanism underlying the selection of homoeologous genes. Thus, variations in the promoter of the cell elongation regulator gene PRE1 have contributed to spinnable fiber formation in cotton. Overexpression of GhPRE1 in transgenic cotton yields longer fibers with improved quality parameters, indicating that this bHLH gene is useful for improving cotton fiber quality. PMID- 29465757 TI - Recent Advances in the Cycloisomerizations of Methylenecyclopropanes using Gold Catalysis. AB - During the past decades, cycloisomerizations of methylenecyclopropanes using gold catalysis have attracted much attention from organic chemists. The different patterns of gold(I)-catalyzed cycloisomerizations of methylenecyclopropanes have been developed, and they can be classified as ring-opening and ring-expansion reaction patterns. This synthetic methodology provides a new approach to novel cyclic- or polycyclic compounds. The corresponding products have great potential for material science, medicinal chemistry and total synthesis. This Concept article will mainly focus on the recent advances in the cycloisomerizations of methylenecyclopropanes in the past four years. PMID- 29465758 TI - An Adverse Effect of Higher Catalyst Loading and Longer Reaction Time on Enantioselectivity in an Organocatalytic Multicomponent Reaction. AB - An enantioselective organocatalytic multicomponent reaction of aldehydes, ketones, and Meldrum's acid has been developed. A cinchona-based primary amine (1 mol %) catalyses the multicomponent reaction via the formation of the Knoevenagel product and a chiral enamine to form enantiopure delta-keto Meldrum's acids in a tandem catalytic pathway. An adverse effect of higher catalyst loading and longer reaction time on enantioselectivity was studied. This mild protocol provides an easy access to enantiopure carboxylic acids, esters and amides and the method is scalable on a gram quantity. DFT calculations were carried out on the proposed reaction mechanism and they were in close agreement with the experimental results. PMID- 29465759 TI - Development of a method to preliminarily embed tissue samples using low melting temperature fish gelatin before sectioning: A technical note. AB - Embedding of tissue samples that maintains a desired orientation is critical for preparing sections suitable for diagnosis and study objectives. Methods to prepare tissue sections include: (i) paraffin embedding or snap-freezing followed by microtome or cryostat sectioning; and (ii) agarose embedding followed by cutting on a vibrating microslicer. Although these methods are useful for routine laboratory work, preparation of small and fragile tissues such as mouse organs, small human biopsy samples, and cultured floating spheres is difficult and requires special skills. In particular, tissue specimen orientation can be lost during embedding in molds and subsequent sectioning. Here, we developed a method using low melting temperature (LM) gelatin either alone or mixed with agarose to preliminarily embed collected tissues that are either prefixed or unfixed, followed by conventional fixation, paraffin embedding, freezing, and sectioning. The advantage of the method is that the LM gelatin and its mixture with agarose can be handled at room temperature but quickly hardens at 4 degrees C, which allows embedding, trimming, and arranging of small and fragile tissues in a desired orientation and are compatible with traditional stainings. Thus, this method can have various laboratory applications and can be modified according to the needs of each laboratory.

AB - Neuroblastoma is the most common tumor diagnosed in children and infants, with high recurrence and poor prognosis. Angelica sinensis polysaccharide (AP) whose average molecular weight is 72,900 Da possesses various bioactivities. We aimed to explore the effects of AP on neuroblastoma SH-SY5Y cells as well as the underlying mechanisms. Effects of AP on cell viability, proliferation, apoptosis, migration, invasion, and expressions of long noncoding RNA H19 (lncRNA-H19), microRNA (miR)-675, and CD44 were assessed. Then, effects of miR-675 overexpression on AP-treated cells were analyzed. Next, expression of key kinases in the PI3K/AKT and JAK/ STAT pathways was detected. The possible target gene of miR-675 was finally explored. Cell viability was reduced by 200-500 ug/mL AP. Meanwhile, AP repressed cell proliferation, migration, and invasion, but induced apoptosis. Expressions of lncRNA-H19 and miR-675 were upregulated in neuroblastoma cells, and were downregulated by AP. AP was also identified to upregulate CD44. We next found AP affected SH-SY5Y cells through downregulating miR-675. Key kinases in the PI3K/AKT and JAK/STAT pathways were downregulated by AP stimulation, while these downregulations were abrogated by miR-675 overexpression. KIF1B isoform beta (KIF1Bbeta) is proved to be a target of miR 675. In conclusion, AP was first identified to inhibit proliferation, migration, and invasion but induce apoptosis. Furthermore, AP might repress tumorigenesis of SH-SY5Y cells through miR-675-mediated inactivation of the PI3K/AKT and JAK/STAT pathways. Besides, KIF1Bbeta might be a target of miR-675. PMID- 29465761 TI - Tumor deposits in salivary gland tumors. AB - Tumor deposits (TDs), identified in different types of carcinomas are associated with poor prognosis. Salivary gland tumors were evaluated for the first time for TDs in this series. Pathological and clinical features of 25 salivary gland carcinomas primarily treated surgically including neck dissection were determined and all cases were evaluated for TDs in dissection specimens. Seven patients (28%) had TDs. There was no difference for TDs when histological type, tumor grade, tumor localization, pT, pN stage, surgical margin, lymphovascular, perineural invasion, local recurrence, distant metastatic disease and overall survival were considered. Disease-free survival rates at 12 and 24 months were 52.5%, 28.6% and 73.3%, 57.1%, for cases with and without TDs (P = 0.463). Overall survival rates at 12 and 24 months for these groups were 85.7% and 57.1 versus 86.7% and 66.7% respectively (P = 0.916). Mean estimated recurrence-free survival time for all cases, TD negative and TD positive cases were: 171.86, 182.72 and 82.42 months, respectively. Mean estimated overall survival time for these groups were 175.80, 186.489 and 89.70 months, respectively. TDs were described in salivary gland tumors for the first time in this series and seem to be associated with poor prognosis requiring further evaluation in larger series. PMID- 29465762 TI - Antitumor activity of pan-HER inhibitors in HER2-positive gastric cancer. AB - Molecularly targeted therapy has enabled outstanding advances in cancer treatment. Whereas various anti-human epidermal growth factor receptor 2 (HER2) drugs have been developed, trastuzumab is still the only anti-HER2 drug presently available for gastric cancer. In this study, we propose novel treatment options for patients with HER2-positive gastric cancer. First, we determined the molecular profiles of 12 gastric cancer cell lines, and examined the antitumor effect of the pan-HER inhibitors afatinib and neratinib in those cell lines. Additionally, we analyzed HER2 alteration in 123 primary gastric cancers resected from Japanese patients to clarify possible candidates with the potential to respond to these drugs. In the drug sensitivity analysis, both afatinib and neratinib produced an antitumor effect in most of the HER2-amplified cell lines. However, some cells were not sensitive to the drugs. When the molecular profiles of the cells were compared based on the drug sensitivities, we found that cancer cells with lower mRNA expression levels of IGFBP7, a tumor suppressor gene that inhibits the activation of insulin-like growth factor-1 receptor (IGF-1R), were less sensitive to pan-HER inhibitors. A combination therapy consisting of pan-HER inhibitors and an IGF-1R inhibitor, picropodophyllin, showed a notable synergistic effect. Among 123 clinical samples, we found 19 cases of HER2 amplification and three cases of oncogenic mutations. In conclusion, afatinib and neratinib are promising therapeutic options for the treatment of HER2-amplified gastric cancer. In addition to HER2 amplification, IGFBP7 might be a biomarker of sensitivity to these drugs, and IGF-1R-targeting therapy can overcome drug insensitiveness in HER2-amplified gastric cancer. PMID- 29465764 TI - Comparison of two prognostic models in trauma outcome. AB - BACKGROUND: The Trauma Audit and Research Network (TARN) in the UK publicly reports hospital performance in the management of trauma. The TARN risk adjustment model uses a fractional polynomial transformation of the Injury Severity Score (ISS) as the measure of anatomical injury severity. The Trauma Mortality Prediction Model (TMPM) is an alternative to ISS; this study compared the anatomical injury components of the TARN model with the TMPM. METHODS: Data from the National Trauma Data Bank for 2011-2015 were analysed. Probability of death was estimated for the TARN fractional polynomial transformation of ISS and compared with the TMPM. The coefficients for each model were estimated using 80 per cent of the data set, selected randomly. The remaining 20 per cent of the data were used for model validation. TMPM and TARN were compared using calibration curves, measures of discrimination (area under receiver operating characteristic curves; AUROC), proximity to the true model (Akaike information criterion; AIC) and goodness of model fit (Hosmer-Lemeshow test). RESULTS: Some 438 058 patient records were analysed. TMPM demonstrated preferable AUROC (0.882 for TMPM versus 0.845 for TARN), AIC (18 204 versus 21 163) and better fit to the data (32.4 versus 153.0) compared with TARN. CONCLUSION: TMPM had greater discrimination, proximity to the true model and goodness-of-fit than the anatomical injury component of TARN. TMPM should be considered for the injury severity measure for the comparative assessment of trauma centres. PMID- 29465763 TI - The role of bradykinin receptor type 2 in spontaneous extravasation in mice skin: implications for non-allergic angio-oedema. AB - BACKGROUND AND PURPOSE: Non-allergic angio-oedema is a life-threatening disease mediated by activation of bradykinin type 2 receptors (B2 receptors). The aim of this study was to investigate whether activation of B2 receptors by endogenous bradykinin contributes to physiological extravasation. This may shed new light on the assumption that treatment with an angiotensin converting enzyme inhibitor (ACEi) results in an alteration in the vascular barrier function predisposing to non-allergic angio-oedema. EXPERIMENTAL APPROACH: We generated a new transgenic mouse model characterized by endothelium-specific overexpression of the B2 receptor (B2tg ) and established a non-invasive two-photon laser microscopy approach to measure the kinetics of spontaneous extravasation in vivo. The B2tg mice showed normal morphology and litter size as compared with their transgene negative littermates (B2n ). KEY RESULTS: Overexpression of B2 receptors was functional in conductance vessels and resistance vessels as evidenced by B2 receptor-mediated aortic dilation to bradykinin in presence of non-specific COX inhibitor diclofenac and by significant hypotension in B2tg respectively. Measurement of dermal extravasation by Miles assay showed that bradykinin induced extravasation was significantly increased in B2tg as compared with B2n . However, neither endothelial overexpression of B2 receptors nor treatment with the ACEi moexipril or B2 antagonist icatibant had any effect on spontaneous extravasation measured by two-photon laser microscopy. CONCLUSIONS AND IMPLICATIONS: Activation of B2 receptors does not appear to be involved in spontaneous extravasation. Therefore, the assumption that treatment with an ACEi results in an alteration in the physiological vascular barrier function predisposing to non-allergic angio oedema is not supported by our findings. PMID- 29465765 TI - The role of general anesthesia on traits of neurodevelopmental disorders in a Swedish cohort of twins. AB - BACKGROUND: The role of general anesthetics as a risk factor for possible neurodevelopmental disorders (NDDs) in humans is unresolved. The investigation of the role of anesthetics in the development of postgeneral anesthesia (anesthesia onward) NDDs has proven to be complicated, partly because of the inherent confounding in clinical cohort studies, and partly by the fact that anesthetics are only one part in the complex process of anesthesia-surgery. METHODS: Utilizing the Swedish databases Child and Adolescent Twins Study in Sweden (CATSS) and National Patient Register (NPR), we investigated twins discordant for anesthesia, born between 1997 and 2004 for traits of NDDs. We identified 68 twin pairs discordant for anesthesia and explored traits of Attention Deficit/Hyperactivity Disorder (ADHD), Learning Disability (LD), and Autism Spectrum Disorder (ASD) in them while simultaneously taking congenital abnormalities and systemic disorders (CSDs) into account. We analyzed the possible effect of anesthesia on neurodevelopmental problems, and we analyzed the within-pair differences using conditional linear regression. RESULTS: Twins with a recorded episode of anesthesia had higher traits of NDDs than twins without; similarly twins with CSDs had higher mean scores on all traits than twins without CSDs. The within-pair analyses suggested that exposure to anesthesia was associated with higher scores of ADHD (regression coefficient 1.02 and 95% confidence intervals: 0.27-1.78) in monozygotic (MZ) twins discordant for anesthesia. This effect remained when adjusting for congenital abnormalities. DISCUSSION: Our finding that traits of ADHD were slightly associated with anesthesia in a genetically sensitive design is in need of replication and warrants further investigation. Future studies should aim to elucidate mechanisms behind this possible association (e.g. anesthetics doses, age at exposure, exposure duration). PMID- 29465766 TI - Segmentectomy versus lobectomy in early non-small cell lung cancer of 2 cm or less in size: A population-based study. AB - BACKGROUND AND OBJECTIVE: Standard surgical management for early stage lung cancer is lobectomy with mediastinal lymph node dissection. The feasibility of limited resection remains controversial; we retrospectively assessed lung cancer specific survival (LCSS) and overall survival (OS) in early stage non-small cell lung cancer (NSCLC) to evaluate whether segmentectomy is comparable to standard lobectomy. METHODS: Patients with primary NSCLC of 20 mm or less who were diagnosed from 2000 to 2014 were extracted from the Surveillance, Epidemiology, and End Results (SEER) database. To compare the two surgical interventions, a propensity score analysis was performed between lobectomy and segmentectomy. RESULTS: Of the 15 358 patients analysed, there were 14 549 lobectomies and 809 segmentectomies. The 5-year OS was 76% for the lobectomy group and 74.4% for the segmentectomy group. There were no significant differences in OS or LCSS among patients who underwent lobectomy versus segmentectomy, as demonstrated by the propensity-matched hazard ratio (HR) for OS (HR: 1.195, 95% CI: 0.993-1.439) and LCSS (HR: 1.124, 95% CI: 0.860-1.469). The inverse propensity-weighted analysis also supported these results. Segmentectomy was more likely to be performed in elderly patients. In the subset of patients aged >=75 years, the segmentectomy group demonstrated comparable OS (HR: 1.17, 95% CI: 0.87-1.58, P = 0.31) and LCSS (HR: 0.94, 95% CI: 0.59-1.51, P = 0.81), compared with the lobectomy group. CONCLUSION: Equivalent OS and LCSS were demonstrated in patients with primary NSCLC of 20 mm or less without lymph node or distant metastasis. PMID- 29465767 TI - Molecular characteristics of rhesus macaque interleukin-22: cloning, in vitro expression and biological activities. AB - Interleukin-22 (IL-22) is a potential therapeutic agent for diseases driven by epithelial injury. To characterize the IL-22 expressed by rhesus macaques, animals that are irreplaceable for human disease research, rhesus macaque IL-22 (rhIL-22) was cloned and expressed, and its biological activity and in vivo distribution were examined. It was found that the rhIL-22 gene consists of five introns and six exons, including a short non-coding exon starting 22 bp downstream of a putative TATA box. The amino acid sequence of rhIL-22 showed 95.5% identity to that of humans, and it shared two conserved disulphide bonds, three N-glycosylation sites and all the critical residues for binding to IL-22R1. High levels of IL-22 mRNA were observed in the liver, pancreas, lymphoid tissues and especially in the outer-body barriers such as the intestinal tract of rhesus macaques. Functionally, purified rhIL-22 has a similar but a little earlier effect on signal transducer and activator of transcription 3 phosphorylation at Tyr705 compared with that of commercial human IL-22. The expression of the antibacterial proteins beta-defensin-2, S100A8, S100A9, RegIIIalpha and Muc1 by HT-29 cells was largely upregulated after stimulation with rhIL-22. Recombinant rhIL-22 could also significantly promote the proliferation of human intestinal epithelial cells without affecting cell apoptosis. These data indicate that rhesus macaque IL-22 is highly similar to that of humans in both structure and function, and tests of therapeutic effects of human IL-22 on human diseases in rhesus macaques are warranted. PMID- 29465768 TI - Controls on denitrification potential in nitrate-rich waterways and riparian zones of an irrigated agricultural setting. AB - Denitrification, the microbial conversion of NO3- to N gases, is an important process contributing to whether lotic and riparian ecosystems act as sinks for excess NO3- from agricultural activities. Though agricultural waterways and riparian zones have been a focus of denitrification research for decades, almost none of this research has occurred in the irrigated agricultural settings of arid and semiarid climates. In this study, we conducted a broad survey of denitrification potential in riparian soils and channel sediments from 79 waterway reaches in the irrigated agricultural landscape of California's Central Valley. With this approach, we sought to capture the wide range of variation that arose from diverse waterway management and fluctuating flow conditions, and use this variation to identify promising management interventions. We explored associations of denitrification potentials with surface water NO3- -N, organic matter, flow conditions, vegetation cover, near-channel riparian bank slope, and channel geomorphic features using generalized linear mixed models. We found strong associations of sediment denitrification potentials with reach flow conditions, which we hypothesize was the result of variation in microbial communities' tolerance to dry-wet cycles. Denitrification potentials in riparian soils, in contrast, did not appear affected by flow conditions, but instead were associated with organic matter, vegetation cover, and bank slope in the riparian zone. These results suggest a strong need for further work on how denitrification responds to varying flow conditions and dry-wet cycles in non-perennial lotic ecosystems. Our findings also demonstrate that denitrifier communities respond to key features of waterway management, which can therefore be leveraged to control denitrification through a variety of management actions. PMID- 29465769 TI - X-ray-enhanced cancer cell migration requires the linker of nucleoskeleton and cytoskeleton complex. AB - The linker of nucleoskeleton and cytoskeleton (LINC) complex is a multifunctional protein complex that is involved in various processes at the nuclear envelope, including nuclear migration, mechanotransduction, chromatin tethering and DNA damage response. We recently showed that a nuclear envelope protein, Sad1 and UNC84 domain protein 1 (SUN1), a component of the LINC complex, has a critical function in cell migration. Although ionizing radiation activates cell migration and invasion in vivo and in vitro, the underlying molecular mechanism remains unknown. Here, we examined the involvement of the LINC complex in radiation enhanced cell migration and invasion. A sublethal dose of X-ray radiation promoted human breast cancer MDA-MB-231 cell migration and invasion, whereas carbon ion beam radiation suppressed these processes in a dose-dependent manner. Depletion of SUN1 and SUN2 significantly suppressed X-ray-enhanced cell migration and invasion. Moreover, depletion or overexpression of each SUN1 splicing variant revealed that SUN1_888 containing 888 amino acids of SUN1 but not SUN1_916 was required for X-ray-enhanced migration and invasion. In addition, the results suggested that X-ray irradiation affected the expression level of SUN1 splicing variants and a SUN protein binding partner, nesprins. Taken together, our findings supported that the LINC complex contributed to photon-enhanced cell migration and invasion. PMID- 29465770 TI - Cookie-cutter shark Isistius spp. predation upon different tuna species from the south-western Atlantic Ocean. AB - The predation of cookie-cutter sharks Isistius spp. upon the early life stages of yellowfin tuna Thunnus albacares, skipjack tuna Katsuwonus pelamis and little tunny Euthynnus alletteratus are described. New evidence suggesting a connection between commercial fishing and predation by Isistius sp. is presented, with these sharks biting tunas hooked in surface waters during daylight. The healing patterns of the wounds made by the sharks are described in detail and, although such damage is known to negatively influence market price elsewhere, it is not the case on the south-east Brazilian coast. PMID- 29465771 TI - Site-Specific Studies of Nucleosome Interactions by Solid-State NMR Spectroscopy. AB - Chromatin function depends on a dense network of interactions between nucleosomes and a wide range of proteins. A detailed description of these protein-nucleosome interactions is required to reach a full molecular understanding of chromatin function in both genetics and epigenetics. Herein, we show that the structure, dynamics, and interactions of nucleosomes can be interrogated in a residue specific manner by using state-of-the-art solid-state NMR spectroscopy. Using sedimented nucleosomes, high-resolution spectra were obtained for both flexible histone tails and the non-mobile histone core. Through co-sedimentation of a nucleosome-binding peptide, we demonstrate that protein-binding sites on the nucleosome surface can be determined. We believe that this approach holds great promise as it is generally applicable, extendable to include the structure and dynamics of the bound proteins, and scalable to interactions of proteins with higher-order chromatin structures, including isolated and cellular chromatin. PMID- 29465772 TI - Superhydrophobic Blood-Repellent Surfaces. AB - Superhydrophobic surfaces repel water and, in some cases, other liquids as well. The repellency is caused by topographical features at the nano-/microscale and low surface energy. Blood is a challenging liquid to repel due to its high propensity for activation of intrinsic hemostatic mechanisms, induction of coagulation, and platelet activation upon contact with foreign surfaces. Imbalanced activation of coagulation drives thrombogenesis or formation of blood clots that can occlude the blood flow either on-site or further downstream as emboli, exposing tissues to ischemia and infarction. Blood-repellent superhydrophobic surfaces aim toward reducing the thrombogenicity of surfaces of blood-contacting devices and implants. Several mechanisms that lead to blood repellency are proposed, focusing mainly on platelet antiadhesion. Structured surfaces can: (i) reduce the effective area exposed to platelets, (ii) reduce the adhesion area available to individual platelets, (iii) cause hydrodynamic effects that reduce platelet adhesion, and (iv) reduce or alter protein adsorption in a way that is not conducive to thrombus formation. These mechanisms benefit from the superhydrophobic Cassie state, in which a thin layer of air is trapped between the solid surface and the liquid. The connections between water- and blood repellency are discussed and several recent examples of blood-repellent superhydrophobic surfaces are highlighted. PMID- 29465773 TI - Chemical priming of immunity without costs to plant growth. AB - beta-Aminobutyric acid (BABA) induces broad-spectrum disease resistance, but also represses plant growth, which has limited its exploitation in crop protection. BABA perception relies on binding to the aspartyl-tRNA synthetase (AspRS) IBI1, which primes the enzyme for secondary defense activity. This study aimed to identify structural BABA analogues that induce resistance without stunting plant growth. Using site-directed mutagenesis, we demonstrate that the (l)-aspartic acid-binding domain of IBI1 is critical for BABA perception. Based on interaction models of this domain, we screened a small library of structural BABA analogues for growth repression and induced resistance against biotrophic Hyaloperonospora arabidopsidis (Hpa). A range of resistance-inducing compounds were identified, of which (R)-beta-homoserine (RBH) was the most effective. Surprisingly, RBH acted through different pathways than BABA. RBH-induced resistance (RBH-IR) against Hpa functioned independently of salicylic acid, partially relied on camalexin, and was associated with augmented cell wall defense. RBH-IR against necrotrophic Plectosphaerella cucumerina acted via priming of ethylene and jasmonic acid defenses. RBH-IR was also effective in tomato against Botrytis cinerea. Metabolic profiling revealed that RBH, unlike BABA, does not majorly affect plant metabolism. RBH primes distinct defense pathways against biotrophic and necrotrophic pathogens without stunting plant growth, signifying strong potential for exploitation in crop protection. PMID- 29465774 TI - Measuring Resilience to Operational Stress in Canadian Armed Forces Personnel. AB - Adaptability to stress is governed by innate resilience, comprised of complex neuroendocrine and immune mechanisms alongside inherited or learned behavioral traits. Based on their capacity to adapt, some people thrive in stressful situations, whereas others experience maladaptation. In our study, we used state of-the-art tools to assess the resilience level in individuals, as well as their susceptibility to developing military stress-induced behavioral and cognitive deficits. To address this complex question, we tested Canadian Armed Forces (CAF) personnel in three distinct stress environments (baselines): during predeployment training, deployment in Afghanistan, and readjustment upon return to Canada. Our comprehensive outcome measures included psychometric tests, saliva biomarkers, and computerized cognitive tests that used the Cambridge Neuropsychological Automated Test Battery. Participants were categorized based on initial biomarker measurements as being at low-, moderate-, or high stress-maladaptation risk. Biomarkers showed significant changes (ds = 0.56 to 2.44) between baselines, calculated as "delta" changes. Participants at low stress-maladaptation risk demonstrated minimal changes, whereas those at high stress-maladaptation risk showed significant biomarker variations. The psychometric patterns and cognitive functions were likewise affected across baselines, suggesting that the panel of saliva stress biomarkers could be a useful tool for determining the risk of stress maladaptation that can cause psychological and cognitive decline. PMID- 29465775 TI - Identification of the correlation between illness perception and anxiety level in cancer patients. AB - PURPOSE: To investigate the relationship between the perception of the disease and level of anxiety in patients with cancer. DESIGN AND METHODS: A correlation and descriptive study from a convenience sample of 318 oncological patients aged 18 years and older was done. Subjects were measured with a Patient's Information Form, the Revised Illness Perception Questionnare, and the Strait-Trait Anxiety Inventory. FINDINGS: When evaluated together with most of its subscales, illness perception was found to affect anxiety. PRACTICE IMPLICATIONS: Nurses should evaluate the anxiety levels of the cancer patients in every stage and should educate the patients and their relatives on coping with anxiety. Appropriate treatment and care depending on the illness perception of the cancer patients should be planned by nurses. PMID- 29465776 TI - Fair chances and hard work? Families making sense of inequality and opportunity in 21st-century Britain. AB - In British social mobility discourse, the rhetoric of fair access can obscure wider issues of social justice. While socio-economic inequalities continue to shape young people's lives, sociological work on class dis-identification suggests social class is less obviously meaningful as a source of individual and collective identity. This paper considers subjective understandings of the post 16 education and employment landscape in this context, drawing on qualitative research exploring the aspirations of young men and women as they completed compulsory education in north-west England, and the hopes their parents had for their future. It shows how unequal access to resources shaped the older generation's expectations for their children, although this was rarely articulated using the explicit language of class. Their children recognized they faced a difficult job market but embraced the idea that success was possible through hard work. Both generations drew moral boundaries and made judgments based on implicit classed discourses about undeserving others, while at the same time disavowing class identities. There was a more explicit recognition of gender inequality among the parents framed with reference to hopes for greater freedom for their daughters. Opportunities and inequalities were thus understood in complex and sometimes contradictory ways. PMID- 29465777 TI - Expression of MAGE-A and NY-ESO-1 cancer/testis antigens is enriched in triple negative invasive breast cancers. AB - AIMS: A better understanding of the expression of cancer/testis antigens (CTAs) in breast cancer might enable the identification of new immunotherapy options, especially for triple-negative (TN) tumours, which lack expression of the conventional therapeutic targets oestrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2. The aim of this study was to quantify the expression of MAGE-A and NY-ESO-1 CTAs in breast cancer, and relate this to known clinicopathological parameters. METHODS AND RESULTS: We surveyed MAGE-A and NY-ESO-1 expression in an unselected cohort of 367 breast tumours (of which 65 were TN), with accompanying clinical follow-up data, by using immunohistochemical analysis of tissue microarrays. Relevant to their potential as vaccine targets in breast cancer, MAGE-A was expressed in 13% of cases, and NY-ESO-1 in 3.8%, with the majority of tumours showing fairly homogeneous staining within individual tissue cores (~85% of cases with staining in >75% of tumour cells). Most NY-ESO-1 positive cases also expressed MAGE-A (P = 2.06 * 10-9 ), and both were strongly associated with the TN phenotype (P < 0.0001), with the most proliferative and poorly differentiated cases, in paticular, showing genomic instability. This was characterised by coexpression of c-Kit and TTK, and overexpression of p53. CONCLUSIONS: MAGE-A and NY-ESO-1 are frequently expressed in TN breast cancer (~47% and 17% of TN cases, respectively), suggesting that targeting them could be feasible in this patient group. Expression is reasonably homogeneous in positive cases, suggesting that immunohistochemical analysis of tissue biopsies would be a reliable companion biomarker. PMID- 29465778 TI - The O-GlcNAc transferase OGT interacts with and post-translationally modifies the transcription factor HOXA1. AB - HOXA1 belongs to the HOX family of transcription factors which are key regulators of animal development. Little is known about the molecular pathways controlling HOXA1. Recent data from our group revealed distinct partner proteins interacting with HOXA1. Among them, OGT is an O-linked N-acetylglucosamine (O-GlcNAc) transferase modifying a variety of proteins involved in different cellular processes including transcription. Here, we confirm OGT as a HOXA1 interactor, we characterise which domains of HOXA1 and OGT are required for the interaction, and we provide evidence that OGT post-translationally modifies HOXA1. Mass spectrometry experiments indeed reveal that HOXA1 can be phosphorylated on the AGGTVGSPQYIHHSY peptide and that upon OGT expression, the phosphate adduct is replaced by an O-GlcNAc group. PMID- 29465779 TI - Atlantic sturgeon Acipenser oxyrinchus surfacing behaviour. AB - Atlantic sturgeon Acipenser oxyrinchus surfacing behaviour was investigated in Minas Basin (45 degrees 20' N; 64 degrees 00' W) and the Bay of Fundy with pop up satellite archival tags (MiniPAT) measuring physical variables (pressure, temperature, light). Of six tags deployed during June and July, five provided pop up locations and two were recovered after c. 4 months. Analysis of recovered archival data revealed that the frequency of surfacing events was highest (78.9%) when A. oxyrinchus were in Minas Basin at depths <10 m. Surfacing frequency decreased substantially when fish migrated into greater depths of the Bay of Fundy (>40 m). The tidal cycle in Minas Basin had a significant relationship to surfacing frequency, with the most surfacing events (49.5%) occurring on the flood tide, from mid- to high-tide. Surfacing events ranged from 0-12 a day and the maximum number occurred between 2300 and 0300 hours. Maximum surfacing ascent speeds ranged from 0.50 to 4.17 m s-1 and maximum descent speeds ranged from 0.17 to 3.17 m s-1 . Buoyancy control, by gulping air to inflate the gas bladder, is proposed as the main reason for surfacing behaviour in A. oxyrinchus. PMID- 29465780 TI - Inferring species interactions through joint mark-recapture analysis. AB - Introduced species are frequently implicated in declines of native species. In many cases, however, evidence linking introduced species to native declines is weak. Failure to make strong inferences regarding the role of introduced species can hamper attempts to predict population viability and delay effective management responses. For many species, mark-recapture analysis is the more rigorous form of demographic analysis. However, to our knowledge, there are no mark-recapture models that allow for joint modeling of interacting species. Here, we introduce a two-species mark-recapture population model in which the vital rates (and capture probabilities) of one species are allowed to vary in response to the abundance of the other species. We use a simulation study to explore bias and choose an approach to model selection. We then use the model to investigate species interactions between endangered humpback chub (Gila cypha) and introduced rainbow trout (Oncorhynchus mykiss) in the Colorado River between 2009 and 2016. In particular, we test hypotheses about how two environmental factors (turbidity and temperature), intraspecific density dependence, and rainbow trout abundance are related to survival, growth, and capture of juvenile humpback chub. We also project the long-term effects of different rainbow trout abundances on adult humpback chub abundances. Our simulation study suggests this approach has minimal bias under potentially challenging circumstances (i.e., low capture probabilities) that characterized our application and that model selection using indicator variables could reliably identify the true generating model even when process error was high. When the model was applied to rainbow trout and humpback chub, we identified negative relationships between rainbow trout abundance and the survival, growth, and capture probability of juvenile humpback chub. Effects on interspecific interactions on survival and capture probability were strongly supported, whereas support for the growth effect was weaker. Environmental factors were also identified to be important and in many cases stronger than interspecific interactions, and there was still substantial unexplained variation in growth and survival rates. The general approach presented here for combining mark-recapture data for two species is applicable in many other systems and could be modified to model abundance of the invader via other modeling approaches.

AB - BACKGROUND: Despite the high incidence of breast cancer worldwide, methods for early non-invasive diagnosis and sensitive and specific prognostic evaluation remain difficult. In this study, we investigated microwave parameters as a potential non-invasive approach to detect breast cancer. METHODS: Samples of freshly excised breast tissues (n = 509) from 98 patients were identified as normal, benign tumor, or malignant cancer via histology. Further samples were prepared and the microwave effective dielectric permittivity and effective conductivity were measured every 0.0375 GHz from 0.5 GHz to 8 GHz. These parameters were compared among the breast tissue types. RESULTS: The effective relative permittivity and effective conductivity at each frequency was significantly higher in breast cancer tissues compared with benign tumors, which in turn was significantly higher than in normal breast tissue. The standard deviation of each parameter was narrowest at ~2.5 GHz in both normal and malignant breast tissues. CONCLUSIONS: The effective dielectric permittivity and effective conductivity, measured via microwave technology, could differentiate breast cancer from normal and benign tumor tissues.

AB - A new antimonato polyoxovanadate {Zn(en)3 }3 [V15 Sb6 O42 (H2 O)]?3 en?10 H2 O (en=ethylenediamine) synthesized under hydrothermal conditions exhibits remarkable solubility in water. Electrospray ionization mass spectrometry (ESI MS) investigations on an aqueous solution demonstrate that the cluster core remains fully intact for 72 h. At longer times, slow transformation into a {V14 Sb8 O42 } cluster is observed. The conversion reaches 50 % after 14 days and is complete after approximately 20 days. The rate of this {V15 Sb6 }->{V14 Sb8 } cluster transformation is significantly increased in the presence of ammonium acetate. Applying the new compound as a synthon in the presence of 1,10 phenanthroline (phen) led to crystallization of {Zn(phen)3 }2 [Zn(en)2 V15 Sb6 O42 (H2 O)]?23 H2 O after a short reaction time, whereas addition of Sb2 O3 led to fast crystallization of {(Zn(en)2 (H2 O)2 )(Zn(en)2 )}[Zn(en)2 V15 Sb6 O42 (H2 O)] ?8.5 H2 O. In the crystal structure of {Zn(en)3 }3 [V15 Sb6 O42 (H2 O)]?3 en?10 H2 O, the en molecules are seen to be attached to the cluster anion through Sb-N bonds. In the structures of the two new compounds obtained, the [V15 Sb6 O42 (H2 O)]6- anions are expanded by Zn2+ -centered complexes through Zn-O-V bond formation.

PMID- 29465786 TI - Subpopulations of vomeronasal sensory neurons with coordinated coexpression of type 2 vomeronasal receptor genes are differentially dependent on Vmn2r1. AB - The mouse vomeronasal organ is specialized in the detection of pheromones. Vomeronasal sensory neurons (VSNs) express chemosensory receptors of two large gene repertoires, V1R and V2R, which encode G-protein-coupled receptors. Phylogenetically, four families of V2R genes can be discerned as follows: A, B, C, and D. VSNs located in the basal layer of the vomeronasal epithelium coordinately coexpress V2R genes from two families: Approximately half of basal VSNs coexpress Vmn2r1 of family C with a single V2R gene of family A8-10, B, or D ('C1 type of V2Rs'), and the other half coexpress Vmn2r2 through Vmn2r7 of family C with a single V2R gene of family A1-6 ('C2 type V2Rs'). The regulatory mechanisms of the coordinated coexpression of V2Rs from two families remain poorly understood. Here, we have generated two mouse strains carrying a knockout mutation in Vmn2r1 by gene targeting in embryonic stem cells. These mutations cause a differential decrease in the numbers of VSNs expressing a given C1 type of V2R. There is no compensatory expression of Vmn2r2 through Vmn2r7. VSN axons coalesce into glomeruli in the appropriate region of the accessory olfactory bulb in the absence of Vmn2r1. Gene expression profiling by NanoString reveals a differential and graded decrease in the expression levels across C1 type of V2Rs. There is no change in the expression levels of C2 type of V2Rs, with two exceptions that we reclassified as C1 type. Thus, there appears to be a fixed probability of gene choice for a given C2 type of V2R. PMID- 29465787 TI - Nonmotor symptoms evolution during 24 months of bilateral subthalamic stimulation in Parkinson's disease. AB - BACKGROUND: The objective of this study was to investigate 24-month of effects of bilateral subthalamic nucleus (STN) deep brain stimulation (DBS) on nonmotor symptoms in Parkinson's disease (PD). METHODS: In this prospective, observational, multicenter, international study including 67 PD patients undergoing bilateral STN-DBS, we examined the Non-motor Symptom Scale, Non-Motor Symptoms Questionnaire, Parkinson's Disease Questionnaire-8, Scales for Outcomes in Parkinson's Disease-motor examination, -activities of daily living, and complications, and levodopa-equivalent daily dose preoperatively and at 5 and 24 month of follow-up. After checking distribution normality, longitudinal outcome changes were investigated with Friedman tests or repeated-measures analysis of variance and Bonferroni correction for multiple comparisons using multiple tests. Post hoc, Wilcoxon signed rank t tests were computed to compare visits. The strength of clinical responses was analyzed using effect size. Explorative Spearman correlations of change scores from baseline to 24-month follow-up were calculated for all outcomes. RESULTS: The Non-motor Symptom Scale and all other outcome parameters significantly improved from baseline to the 5-month follow-up. From 5 to 24-month, partial decrements in these gains were found. Nonetheless, comparing baseline with 24-month follow-up, significant improvements were observed for the Non-motor Symptom Scale (small effect), Scales for Outcomes in PD-motor examination showed a moderate effect, and Scales for Outcomes in Parkinson's Disease-complications and levodopa-equivalent daily dose showed large effects. Non-motor Symptom Scale change scores from baseline to 24-month follow up correlated significantly with Parkinson's Disease Questionnaire-8, Scales for Outcomes in Parkinson's Disease-activities of daily living, and -motor complications change scores. CONCLUSIONS: This study provides evidence of beneficial effects of bilateral STN-DBS on nonmotor symptoms at 24-month follow up. The extent of nonmotor symptom improvement was directly proportionate to improvements in quality of life, activities of daily living, and motor complications. This study underlines the importance of nonmotor symptoms for holistic assessments of DBS outcomes. (c) 2018 International Parkinson and Movement Disorder Society.

AB - AIMS: To investigate the real treatment outcomes after augmentation enterocystoplasty (AE) of patients with refractory neurogenic lower urinary tract dysfunction. METHODS: Retrospective follow-up in a single center. The videourodynamic data, renal function, incontinence grade, voiding pattern and management, clinical outcome, and complications were evaluated. RESULTS: Seventy nine patients (62 men and 17 women) were included. The mean age at operation was 39.4 +/- 11.6 years and the mean follow-up period was 128.4 +/- 85.2 months. At follow-up, 5 (6.7%) patients had spontaneous voiding, 60 (80%) had to perform clean intermittent catheterization, and 10 (13.3%) chose to keep the indwelling catheter. The catheter-dependent rate was 93.3% and complete catheter-dependent rate was 76%. Renal function of the patients did not appear to be significantly different after AE. Three patients developed end-stage renal disease. The incontinence grade showed significant improvement (P = 0.000). Among all the patients, 41.8% experienced recurrent urinary tract infections requiring medical treatment and 21.5% suffered from chronic diarrhea. Overall, 45.6% of the patients experienced complications requiring surgical interventions, most of which were stones. Life-threatening complications like bowel obstruction and bladder cancer were also noted. Three patients even expired within one year postoperatively. The majority (86.8%) of patients reported moderate to excellent satisfaction with the outcome of AE. CONCLUSIONS: AE is a procedure with long term durability and high rates of patient satisfaction. However, several bothersome complications affecting life quality may occur. Both patients and doctors thus need to consider possible outcomes carefully before the operation.

AB - Current diagnostic and prognostic tools for prostate cancer (PC) are suboptimal, leading to overdiagnosis and overtreatment. Aberrant promoter hypermethylation of specific genes has been suggested as novel candidate biomarkers for PC that may improve diagnosis and prognosis. We here analyzed ST6GALNAC3 and ZNF660 promoter methylation in prostate tissues, and ST6GALNAC3, ZNF660, CCDC181, and HAPLN3 promoter methylation in liquid biopsies. First, using four independent patient sample sets, including a total of 110 nonmalignant (NM) and 705 PC tissue samples, analyzed by methylation-specific qPCR or methylation array, we found that hypermethylation of ST6GALNAC3 and ZNF660 was highly cancer-specific with areas under the curve (AUC) of receiver operating characteristic (ROC) curve analysis of 0.917-0.995 and 0.846-0.903, respectively. Furthermore, ZNF660 hypermethylation was significantly associated with biochemical recurrence in two radical prostatectomy (RP) cohorts of 158 and 392 patients and remained significant also in the subsets of patients with Gleason score <=7 (univariate Cox regression and log-rank tests, P < 0.05), suggesting that ZNF660 methylation analysis can potentially help to stratify low-/intermediate-grade PCs into indolent vs. more aggressive subtypes. Notably, ZNF660 hypermethylation was also significantly associated with poor overall and PC-specific survival in the RP cohort (n = 158) with long clinical follow-up available. Moreover, as proof of principle, we successfully detected highly PC-specific hypermethylated circulating tumor DNA (ctDNA) for ST6GALNAC3, ZNF660, HAPLN3, and CCDC181 in liquid biopsies (serum) from 27 patients with PC vs. 10 patients with BPH, using droplet digital methylation-specific PCR analysis. Finally, we generated a three gene (ST6GALNAC3/CCDC181/HAPLN3) ctDNA hypermethylation model, which detected PC with 100% specificity and 67% sensitivity. In conclusion, we here for the first time demonstrate diagnostic biomarker potential of ST6GALNAC3 and ZNF660 methylation, as well as prognostic biomarker potential of ZNF660. Furthermore, we show that hypermethylation of four genes can be detected in ctDNA in liquid biopsies (serum) from patients with PC. PMID- 29465790 TI - Forkhead box C2 promotes the invasion ability of human trophoblast cells through Hedgehog (Hh) signaling pathway. AB - Embryonic development depends on the normal invasion of trophoblast cells. Forkhead box C2 (FOXC2) is a member of Forkhead box family, which is involved in the tumor cells invasion. The aim of this study was to explore the roles of FOXC2 on the invasion of human trophoblast cells, and further study its molecular mechanism. The mRNA and protein levels of FOXC2 in human normal trophoblast and choriocarcinoma cell lines were analyzed by quantitative real-time PCR (qRT-PCR) and Western blot assays, respectively. Methylthiazolyldiphenyl-tetrazo lium bromide (MTT) and transwell assays were separately performed to detect the adhesion and invasion of normal trophoblast cells treated with exogenous FOXC2 and FOXC2 siRNA. QRT-PCR and Western blot assays were used to test levels of the epithelial-mesenchymal transition (EMT)-related and Hedgehog (Hh) signaling pathway-related factors, respectively. Herein, our results found that the expression levels of FOXC2 in normal trophoblast cells were lower than choriocarcinoma cells. FOXC2 over-expression remarkably strengthened the adhesion and invasion abilities of normal trophoblast cells. Moreover, over-expression of FOXC2 significantly promoted the expression of human leukocyte antigen-G (HLA-G), matrix metalloproteinase-2 (MMP-2), Vimentin, sonic hedgehog (Shh), Glioma associated oncogene homolog 1 (Gli1), and Snail, and inhibited E-cadherin expression. However, it showed the opposite tendency in FOXC2 siRNA group. In addition, there was no significant change in the expression of MMP9 among different groups. Above results illustrated that FOXC2 could promote the invasion ability of normal trophoblast cells by EMT-mediated Hh pathway. PMID- 29465791 TI - Identification and functional analysis of a novel chorion protein essential for egg maturation in the brown planthopper. AB - In insect eggs, the chorion has the essential function of protecting the embryo from external agents during development while allowing gas exchange for respiration. In this study, we found a novel gene, Nilaparvata lugens chorion protein (NlChP), that is involved in chorion formation in the brown planthopper, Nilaparvata lugens. NlChP was highly expressed in the follicular cells of female adult brown planthoppers. Knockdown of NlChP resulted in oocyte malformation and the inability to perform oviposition, and electron microscopy showed that the malformed oocytes had thin and rough endochorion layers compared to the control group. Liquid chromatography with tandem mass spectrometry analysis of the eggshell components revealed four unique peptides that were matched to NlChP. Our results demonstrate that NlChP is a novel chorion protein essential for egg maturation in N. lugens, a hemipteran insect with telotrophic meroistic ovaries. NlChP may be a potential target in RNA interference-based insect pest management.

PMID- 29465793 TI - Modulation of task-related cortical connectivity in the acute and subacute phase after stroke. AB - The functional relevance of cortical reorganization post-stroke is still not well understood. In this study, we investigated task-specific modulation of cortical connectivity between neural oscillations in key motor regions during the early phase after stroke. EEG and EMG recordings were examined from 15 patients and 18 controls during a precision grip task using the affected hand. Each patient attended two sessions in the acute and subacute phase (median of 3 and 34 days) post-stroke. Dynamic causal modelling (DCM) for induced responses was used to investigate task-specific modulations of oscillatory couplings in a bilateral network comprising supplementary motor area (SMA), dorsal premotor cortex (PMd) and primary motor cortex (M1). Fourteen models were constructed for each subject, and the input induced by the experimental manipulation (task) was set to inferior parietal lobule (IPL). Bayesian model selection favoured a fully connected model. A reduced coupling from SMA and intact M1 in the gamma-band (31-48 Hz) to lesioned M1 in the beta-band (15-30 Hz) was observed in patients in the acute phase compared to controls. Behavioural performance improved significantly in the subacute phase, while an increased positive coupling from intact PMd to lesioned M1 and a less negative modulation from lesioned M1 to intact M1 were observed for patients compared to controls both from the gamma-band to the beta-band. We infer that the observed differences in cross-frequency cortical interactions are important for functional recovery. PMID- 29465794 TI - Liver involvement in dengue viral infections. AB - Dengue fever is the commonest viral haemorrhagic fever worldwide and is a leading cause of morbidity and mortality in the tropics. Dengue viral infections are frequently associated with varying degrees of liver injury. Liver injury is more severe in dengue haemorrhagic fever or severe dengue. We review the current knowledge on liver involvement following dengue viral infections and explore the links between clinical manifestations, pathogenesis, and their impact on management. PMID- 29465795 TI - Enhanced Li Storage Stability Induced by Locating Sn in Metal-Organic Frameworks. AB - By locating elemental Sn in an open anionic framework, the particle cracking arising from huge volume expansion of Sn-based anode materials during lithiation/delithiation is alleviated, and the cycling stability is greatly improved. The Sn-based metal-organic framework anode material shows superior cyclic stability, with a capacity retention >92 % (after 200 cycles) and high lithium storage capacity (610 mAh g-1 ). PMID- 29465796 TI - Conserved residues are critical for Haloferax volcanii archaeosortase catalytic activity: Implications for convergent evolution of the catalytic mechanisms of non-homologous sortases from archaea and bacteria. AB - Proper protein anchoring is key to the biogenesis of prokaryotic cell surfaces, dynamic, resilient structures that play crucial roles in various cell processes. A novel surface protein anchoring mechanism in Haloferax volcanii depends upon the peptidase archaeosortase A (ArtA) processing C-termini of substrates containing C-terminal tripartite structures and anchoring mature substrates to the cell membrane via intercalation of lipid-modified C-terminal amino acid residues. While this membrane protein lacks clear homology to soluble sortase transpeptidases of Gram-positive bacteria, which also process C-termini of substrates whose C-terminal tripartite structures resemble those of ArtA substrates, archaeosortases do contain conserved cysteine, arginine and arginine/histidine/asparagine residues, reminiscent of His-Cys-Arg residues of sortase catalytic sites. The study presented here shows that ArtAWT -GFP expressed in trans complements DeltaartA growth and motility phenotypes, while alanine substitution mutants, Cys173 (C173A), Arg214 (R214A) or Arg253 (R253A), and the serine substitution mutant for Cys173 (C173S), fail to complement these phenotypes. Consistent with sortase active site replacement mutants, ArtAC173A GFP, ArtAC173S -GFP and ArtAR214A -GFP cannot process substrates, while replacement of the third residue, ArtAR253A -GFP retains some processing activity. These findings support the view that similarities between certain aspects of the structures and functions of the sortases and archaeosortases are the result of convergent evolution.

The catalytic reactions proceed under very mild conditions in a highly atom-efficient and highly selective fashion to afford the corresponding monohydroborated N-borylformamidine products in high yields. A plausible mechanism is proposed based on stoichiometric and kinetic studies. PMID- 29465798 TI - Sexual conflict and ecology: Species composition and male density interact to reduce male mating harassment and increase female survival. AB - Sexual conflict is a pervasive evolutionary force that can reduce female fitness. Experimental evolution studies in the laboratory might overestimate the importance of sexual conflict because the ecological conditions in such settings typically include only a single species. Here, we experimentally manipulated conspecific male density (high or low) and species composition (sympatric or allopatric) to investigate how ecological conditions affect female survival in a sexually dimorphic insect, the banded demoiselle (Calopteryx splendens). Female survival was strongly influenced by an interaction between male density and species composition. Specifically, at low conspecific male density, female survival increased in the presence of heterospecific males (C. virgo). Behavioral mating experiments showed that interspecific interference competition reduced conspecific male mating success with large females. These findings suggest that reproductive interference competition between con- and heterospecific males might indirectly facilitate female survival by reducing mating harassment from conspecific males. Hence, interspecific competitors can show contrasting effects on the two sexes thereby influencing sexual conflict dynamics. Our results call for incorporation of more ecological realism in sexual conflict research, particularly how local community context and reproductive interference competition between heterospecific males can affect female fitness. PMID- 29465799 TI - Imaging of Al/Fe ratios in synthetic Al-goethite revealed by nanoscale secondary ion mass spectrometry. AB - RATIONALE: Aluminium (Al)-substituted goethite is ubiquitous in soils and sediments. The extent of Al-substitution affects the physicochemical properties of the mineral and influences its macroscale properties. Bulk analysis only provides total Al/Fe ratios without providing information with respect to the Al substitution of single minerals. Here, we demonstrate that nanoscale secondary ion mass spectrometry (NanoSIMS) enables the precise determination of Al-content in single minerals, while simultaneously visualising the variation of the Al/Fe ratio. METHODS: Al-substituted goethite samples were synthesized with increasing Al concentrations of 0.1, 3, and 7 % and analysed by NanoSIMS in combination with established bulk spectroscopic methods (XRD, FTIR, Mossbauer spectroscopy). The high spatial resolution (50-150 nm) of NanoSIMS is accompanied by a high number of single-point measurements. We statistically evaluated the Al/Fe ratios derived from NanoSIMS, while maintaining the spatial information and reassigning it to its original localization. RESULTS: XRD analyses confirmed increasing concentration of incorporated Al within the goethite structure. Mossbauer spectroscopy revealed 11 % of the goethite samples generated at high Al concentrations consisted of hematite. The NanoSIMS data show that the Al/Fe ratios are in agreement with bulk data derived from total digestion and demonstrated small spatial variability between single-point measurements. More advantageously, statistical analysis and reassignment of single-point measurements allowed us to identify distinct spots with significantly higher or lower Al/Fe ratios. CONCLUSIONS: NanoSIMS measurements confirmed the capacity to produce images, which indicated the uniform increase in Al-concentrations in goethite. Using a combination of statistical analysis with information from complementary spectroscopic techniques (XRD, FTIR and Mossbauer spectroscopy) we were further able to reveal spots with lower Al/Fe ratios as hematite. PMID- 29465800 TI - The cycling gonad: retinoic-acid synthesis and degradation patterns during adult zebrafish Danio rerio oogenesis. AB - The expression pattern of genes coding for enzymes of the retinoic acid (RA) synthetic and degradation pathways was characterized in adult female zebrafish Danio rerio. Females were conditioned until maturation and post-spawn expression dynamics were determined. A striking upregulation of cyp26b1, but not cyp26a1, was observed following egg deposition, decreasing to initial levels during recovery. A similar, yet lower, fluctuation was observed for aldh1a2 and rdh10a, the enzymes participating in the two-step RA biosynthesis cascade. The present work highlights the dynamics of the adult D. rerio oogenesis and uncovers novel, yet elusive, metabolic contributors. Possible compartmentalized roles for the different gene paralogue isoforms are discussed. PMID- 29465801 TI - Near-Infrared Light-Controlled Gene Expression and Protein Targeting in Neurons and Non-neuronal Cells. AB - Near-infrared (NIR) light-inducible binding of bacterial phytochrome BphP1 to its engineered partner, QPAS1, is used for optical protein regulation in mammalian cells. However, there are no data on the application of the BphP1-QPAS1 pair in cells derived from various mammalian tissues. Here, we tested the functionality of two BphP1-QPAS1-based optogenetic tools-an NIR- and blue-light-sensing system for control of protein localization (iRIS) and an NIR light-sensing system for transcription activation (TA)-in several cell types, including cortical neurons. We found that the performance of these optogenetic tools often relied on physiological properties of a specific cell type, such as nuclear transport, which could limit the applicability of the blue-light-sensitive component of iRIS. In contrast, the NIR-light-sensing component of iRIS performed well in all tested cell types. The TA system showed the best performance in cervical cancer (HeLa), bone cancer (U-2 OS), and human embryonic kidney (HEK-293) cells. The small size of the QPAS1 component allowed the design of adeno-associated virus (AAV) particles, which were applied to deliver the TA system to neurons. PMID- 29465802 TI - Cholesterol accumulation by suppression of SMT1 leads to dwarfism and improved drought tolerance in herbaceous plants. AB - Dwarfism and drought tolerance are 2 valuable traits in breeding of many crops. In this study, we report the novel physiological roles of cholesterol in regulation of plant growth and drought tolerance. Compared with the wild type, sterol-C24-methyltransferase 1 (SMT1) gene transcript was greatly reduced in a bermudagrass mutant with dwarfism and enhanced drought tolerance, accompanied with cholesterol accumulation, elevated transcript levels of a small group of genes including SAMDC, and increased concentrations of putrescine (Put), spermidine (Spd), and spermine (Spm). Knock-down of OsSMT1 expression by RNA interference resulted in similar phenotypic changes in transgenic rice. Moreover, exogenously applied cholesterol also led to elevated transcripts of a similar set of genes, higher levels of Put, Spd, and Spm, improved drought tolerance, and reduced plant height in both bermudagrass and rice. We revealed that it is Spm, but not Spd, that is responsible for the height reduction in bermudagrass and rice. In conclusion, we suggest that cholesterol induces expression of SAMDC and leads to dwarfism and elevated drought tolerance in plants as a result of the promoted Spd and Spm synthesis. PMID- 29465803 TI - Olaparib is effective in combination with, and as maintenance therapy after, first-line endocrine therapy in prostate cancer cells. AB - A number of prostate cancer (PCa)-specific genomic aberrations (denominated BRCAness genes) have been discovered implicating sensitivity to PARP inhibition within the concept of synthetic lethality. Recent clinical studies show favorable results for the PARP inhibitor olaparib used as single agent for treatment of metastatic castration-resistant PCa. Using 2D and 3D cell culture models mimicking the different treatment and progression stages of PCa, we evaluated a potential use for olaparib in combination with first-line endocrine treatments, androgen deprivation, and complete androgen blockade, and as a maintenance therapy following on from endocrine therapy. We demonstrate that the LNCaP cell line, possessing multiple aberrations in BRCAness genes, is sensitive to olaparib. Additive effects of olaparib combined with endocrine treatments in LNCaP are noted. In contrast, we find that the TMPRSS2:ERG fusion-positive cell lines VCaP and DuCaP do not show signs of synthetic lethality, but are sensitive to cytotoxic effects caused by olaparib. In consequence, additive effects of olaparib with endocrine therapy were not observable in these cell lines, showing the need for synthetic lethality in combination treatment regimens. Additionally, we show that PCa cells remain sensitive to olaparib treatment after initial androgen deprivation implicating a possible use of olaparib as maintenance therapy. In sum, our preclinical data recommend olaparib as a synthetic lethal treatment option in combination or sequenced to first-line endocrine therapy for PCa patients with diagnosed BRCAness.

AB - In vivo optical imaging using fluorescence and bioluminescence is superior to other methods in terms of spatiotemporal resolution and specificity, and represents a new technology for comprehensively studying living organisms in a less invasive way. Nowadays, it is an indispensable technology for studying many aspects of cancer biology, including dynamic invasion and metastasis. In observations of fluorescence or bioluminescence signals in a living body, various problems were caused by optical characteristics such as absorption and scattering and, therefore, observation of deep tissue was difficult. Recent developments in techniques for observation of the deep tissues of living animals overcame this difficulty by improving bioluminescent proteins, fluorescent proteins, and fluorescent dyes, as well as detection technologies such as two-photon excitation microscopy. In the present review, we introduce these technological developments and in vivo application of bioluminescence and fluorescence imaging, and discuss future perspectives on the use of in vivo optical imaging technology in cancer research. PMID- 29465806 TI - Principles of haemophilia care: The Asia-Pacific perspective. AB - Optimal haemophilia care is best established and implemented through a well coordinated plan guided by clearly defined principles and priorities. A document which enunciates those details is therefore important. A successful example of this approach is the definition of principles of haemophilia care (PHC) outlined by the European Association for Haemophilia and Associated Disorders (EAHAD) and also the World Federation of Hemophilia. A similar document applicable to the Asia-Pacific region must take into account not only the highly varied healthcare systems but also the tremendous socio-economic and cultural diversities which impact provision of such care. The Asia-Pacific Haemophilia Working Group (APHWG), representing the countries in this region, has prepared this perspective of the PHC. While endorsing the overall framework outlined by EAHAD, this APHWG document emphasizes regional priorities on education and training of healthcare personnel in the diagnosis and management of hereditary bleeding disorders. Central coordinating agencies with wide stakeholder input, networks of haemophilia treatment centres and national registries as well as robust processes for procurement and distribution of safe and effective clotting factor concentrates (CFCs), implementation of prophylaxis programmes and management of patients with inhibitors should also be developed. The implementation of these strategies should lead to establishment of good comprehensive care programmes. This document should also be an advocacy tool to lobby for improved care for people with haemophilia (PWH) in the region. We urge national healthcare policy makers to consider these principles and initiate strong and decisive action to reach these goals. PMID- 29465807 TI - Revisiting Polyarenes and Related Molecules: An Update of Synthetic Approaches and Structure-Activity-Mechanistic Correlation for Carcinogenesis. AB - A major proportion of basic cause for human cancer has been linked to widespread environmental pollutants including analogs of polyarenes. Search of an effective therapy can be started with the understanding of the generation of such "carcinogens" and their biological interactions. This review is to discuss the syntheses, structural activities, mechanistic and biological studies of polyarenes such as polycyclic aromatic hydrocarbons (PAHs), polycyclic azaarenes (PAAs) and their thia-analogs (PASH). It also summarizes the mechanism of mutagenicity and tumorigenicity via metabolic interventions producing diol epoxide complexes and eventually formation of DNA adducts. It suggests that inhibition of oxidative reactions and formation of diols and epoxides and unspecific intracellular activation of cytochrome P450 enzymes could be approaches in therapy against such mutagenicity and tumorigenicity. Thus, this review reflects that understanding of molecular mechanisms and activations along with a clinical and translational medicine approach would require achieving both prevention and treatment of this atrocity. PMID- 29465808 TI - Investigating the Potential Barrier Function of Nanostructured Materials Formed in Engineered Barrier Systems (EBS) Designed for Nuclear Waste Isolation. AB - Clay and cement are known nano-colloids originating from natural processes or traditional materials technology. Currently, they are used together as part of the engineered barrier system (EBS) to isolate high-level nuclear waste (HLW) metallic containers in deep geological repositories (DGR). The EBS should prevent radionuclide (RN) migration into the biosphere until the canisters fail, which is not expected for approximately 103 years. The interactions of cementitious materials with bentonite swelling clay have been the scope of our research team at the Autonomous University of Madrid (UAM) with participation in several European Union (EU) projects from 1998 up to now. Here, we describe the mineral and chemical nature and microstructure of the alteration rim generated by the contact between concrete and bentonite. Its ability to buffer the surrounding chemical environment may have potential for further protection against RN migration.

PMID- 29465809 TI - IDH2 is a novel diagnostic and prognostic serum biomarker for non-small-cell lung cancer. AB - Lung cancer is the most common leading cause of cancer-related death worldwide. Late diagnosis contributes to a high mortality rate and poor survival of this cancer. In our previous study, we found that IDH2 polymorphism rs11540478 is a risk factor for lung cancer. Here, we examined IDH2 protein expression in culture medium in which two non-small-cell lung cancer (NSCLC) cell lines, H460 and A549, were growing. We found that the IDH2 protein was elevated in the culture supernatant fraction in a time- and cell number-dependent manner. Next, we used ELISA methods to examine IDH2 protein level in serum from patients with NSCLC and healthy controls. We found that IDH2 protein levels in serum could distinguish NSCLC patients from healthy controls with an AUC (area under the curve) of 0.83 (95% confidence interval = 0.79-0.88). The IDH2 level was decreased in serum from NSCLC postsurgical patients compared with the paired presurgical serum. High serum IDH2 levels appear to correlate with poor survival in patients with NSCLC. These results suggest that IDH2 levels in the serum could be a new effective biomarker for the diagnosis and prognosis of NSCLC. PMID- 29465811 TI - CK1epsilon and p120-catenin control Ror2 function in noncanonical Wnt signaling. AB - Canonical and noncanonical Wnt pathways share some common elements but differ in the responses they evoke. Similar to Wnt ligands acting through the canonical pathway, Wnts that activate the noncanonical signaling, such as Wnt5a, promote Disheveled (Dvl) phosphorylation and its binding to the Frizzled (Fz) Wnt receptor complex. The protein kinase CK1epsilon is required for Dvl/Fz association in both canonical and noncanonical signaling. Here we show that differently to its binding to canonical Wnt receptor complex, CK1epsilon does not require p120-catenin for the association with the Wnt5a co-receptor Ror2. Wnt5a promotes the formation of the Ror2-Fz complex and enables the activation of Ror2 bound CK1epsilon by Fz-associated protein phosphatase 2A. Moreover, CK1epsilon also regulates Ror2 protein levels; CK1epsilon association stabilizes Ror2, which undergoes lysosomal-dependent degradation in the absence of this kinase. Although p120-catenin is not required for CK1epsilon association with Ror2, it also participates in this signaling pathway as p120-catenin binds and maintains Ror2 at the plasma membrane; in p120-depleted cells, Ror2 is rapidly internalized through a clathrin-dependent mechanism. Accordingly, downregulation of p120 catenin or CK1epsilon affects late responses to Wnt5a that are also sensitive to Ror2, such as SIAH2 transcription, cell invasion, or cortical actin polarization. Our results explain how CK1epsilon is activated by noncanonical Wnt and identify p120-catenin and CK1epsilon as two critical factors controlling Ror2 function.

AB - The emergence of multidrug-resistant bacteria and pathogens has created an urgent need for the development of new antibiotics. Herein we report our investigations into the broad-spectrum activity of an easily prepared water-soluble polyaminosterol compound, namely claramine A1, against both drug-sensitive and drug-resistant Gram-negative and Gram-positive bacterial strains. We also report its peculiar mechanism of action, which differs from that of all the other well known classes of antibiotics, toward Gram-negative and Gram-positive bacteria. Given their low cytotoxicity, this class of compounds based on claramine A1 could constitute an effective response to combat the emergence of multidrug-resistant bacteria and nosocomial diseases. PMID- 29465812 TI - The role of salt for immune cell function and disease. AB - The immune system evolved to protect organisms from invading pathogens. A network of pro- and anti-inflammatory cell types equipped with special effector molecules guarantees efficient elimination of intruders like viruses and bacteria. However, imbalances can lead to an excessive response of effector cells incurring autoimmune or allergic diseases. An interplay of genetic and environmental factors contributes to autoimmune diseases and recent studies provided evidence for an impact of dietary habits on the immune status and related disorders. Western societies underwent a change in lifestyle associated with changes in food consumption. Salt (sodium chloride) is one component prevalent in processed food frequently consumed in western countries. Here we summarize recent advances in understanding the mechanisms behind the effects of sodium chloride on immune cells like regulatory T cells (Tregs) and T helper (TH ) 17 cells and its implication as a risk factor for several diseases. PMID- 29465815 TI - Revealing the Transient Concentration of CO2 in a Mixed-Matrix Membrane by IR Microimaging and Molecular Modeling. AB - Through IR microimaging the spatially and temporally resolved development of the CO2 concentration in a ZIF-8@6FDA-DAM mixed matrix membrane (MMM) was visualized during transient adsorption. By recording the evolution of the CO2 concentration, it is observed that the CO2 molecules propagate from the ZIF-8 filler, which acts as a transport "highway", towards the surrounding polymer. A high-CO2 concentration layer is formed at the MOF/polymer interface, which becomes more pronounced at higher CO2 gas pressures. A microscopic explanation of the origins of this phenomenon is suggested by means of molecular modeling. By applying a computational methodology combining quantum and force-field based calculations, the formation of microvoids at the MOF/polymer interface is predicted. Grand canonical Monte Carlo simulations further demonstrate that CO2 tends to preferentially reside in these microvoids, which is expected to facilitate CO2 accumulation at the interface.

(Ar=Ph, 5 a; 4-DMP, 5 b) and [(SIPrAr )]. (Ar=Ph, 6 a; 4-Tol, 6 b). Each of 5 a,b and 6 a,b exhibited a doublet EPR signal, a characteristic of monoradical species. The first solid-state characterization of NHC-derived carbon-centered radicals 6 a,b by single-crystal X-ray diffraction is reported. DFT calculations indicate that the unpaired electron is mainly located at the original carbene carbon atom and stabilized by partial delocalization over the adjacent aryl group. PMID- 29465817 TI - Spectroscopic and Hydrodynamic Characterisation of DNA-Linked Gold Nanoparticle Dimers in Solution using Two-Photon Photoluminescence. AB - Two-photon photoluminescence (TPPL) emission spectra of DNA-gold nanoparticle (AuNP) monoconjugates and the corresponding DNA-linked AuNP dimers are obtained by photon time-of-flight spectroscopy. This technique is combined with two-photon photoluminescence fluctuation correlation spectroscopy (TPPL-FCS) to simultaneously monitor the optical and hydrodynamic behaviour of these nano assemblies in solution, with single-particle sensitivity and microsecond temporal resolution. In this study, the AuNPs have an average core diameter of 12 nm, which renders their dark-field plasmonic light scattering too weak for single particle imaging. Moreover, as a result of the lack of plasmonic coupling in the dimers, the optical extinction, scattering and photoluminescence spectra of the DNA-AuNP complexes are not sufficiently different to distinguish between monomers and dimers. The use of TPPL-FCS successfully addresses these bottlenecks and enables the distinction between AuNP monomers and AuNP dimers in solution by measurement of their hydrodynamic rotational and translational diffusion. PMID- 29465818 TI - Calcineurin is required for male sex pheromone biosynthesis and female acceptance. AB - Lepidoptera sex pheromone biosynthesis is regulated by pheromone biosynthesis activating neuropeptide (PBAN). PBAN regulates not only female sex pheromone biosynthesis but also male sex pheromone biosynthesis. Previous research has confirmed that PBAN regulates sex pheromone biosynthesis using Ca2+ as a secondary messenger in all examined species to date. However, the downstream signal of Ca2+ has remained elusive. In the present study, calcineurin A (CNA), a downstream signal of Ca2+ , was discovered in Helicoverpa armigera male hairpencil and named HaCNA. Sequence analysis demonstrated that the open reading frame of HaCNA contains 1488 nucleotides encoding 495 amino acid residues. A homology search revealed that HaCNA shares a high amino acid identity with the CNA of other insects. Developmental and spatial expression analyses revealed that the mRNA levels of HaCNA peaked at 24 h after emergence and that HaCNA expression was ubiquitous in all examined tissues. Activity analysis revealed that PBAN activates HaCNA, and a Ca2+ inhibitor, Lacl3 , attenuated the effect of PBAN by decreasing HaCNA activity. Pharmacological inhibitor and RNA interference mediated knockdown assays revealed that both activity inhibition and decreased mRNA levels of HaCNA led to a significant decrease in the production of the male sex pheromone components [octadecanol and (Z)-11 hexadecanol)] and in the efficacy of female mating acceptance. Our results demonstrate that HaCNA acts as downstream signal of PBAN/Ca2+ and plays an important role in PBAN-induced male sex pheromone biosynthesis and female mating acceptance.

AB - The performance of the present-day scanning electron microscopy (SEM) extends far beyond delivering electronic images of the surface topography. Oxide dispersion strengthened (ODS) steel is on of the most promising materials for the future nuclear fusion reactor because of its good radiation resistance, and higher operation temperature up to 750 degrees C. The microstructure of ODS should not exceed tens of nm, therefore there is a strong need in a fast and reliable technique for their characterization. In this work, the results of low-kV SEM characterization of nanoprecipitates formed in the ODS matrix are presented. Application of highly sensitive photo-diode BSE detector in SEM imaging allowed for the registration of single nm-sized precipitates in the vicinity of the ODS alloys. The composition of the precipitates has been confirmed by TEM-EDS. PMID- 29465820 TI - Literally Green Chemical Synthesis of Artemisinin from Plant Extracts. AB - Active pharmaceutical ingredients are either extracted from biological sources where they are synthesized in complex, dynamic environments-or prepared in stepwise chemical syntheses by reacting pure reagents and catalysts under controlled conditions. A combination of these two approaches, where plant extracts containing reagents and catalysts are utilized in intensified chemical syntheses, creates expedient and sustainable processes. We illustrate this principle by reacting crude plant extract, oxygen, acid, and light to produce artemisinin, a key active pharmaceutical ingredient of the most powerful antimalarial drugs. The traditionally discarded extract of Artemisia annua plants contains dihydroartemisinic acid-the final biosynthetic precursor-as well as chlorophyll, which acts as a photosensitizer. Efficient irradiation with visible light in a continuous-flow setup produces artemisinin in high yield, and the artificial biosynthetic process outperforms syntheses with pure reagents. PMID- 29465821 TI - Quantitative magnetic resonance spectroscopy at 3T based on the principle of reciprocity. AB - Quantification of magnetic resonance spectroscopy signals using the phantom replacement method requires an adequate correction of differences between the acquisition of the reference signal in the phantom and the measurement in vivo. Applying the principle of reciprocity, sensitivity differences can be corrected at low field strength by measuring the RF transmitter gain needed to obtain a certain flip angle in the measured volume. However, at higher field strength the transmit sensitivity may vary from the reception sensitivity, which leads to wrongly estimated concentrations. To address this issue, a quantification approach based on the principle of reciprocity for use at 3T is proposed and validated thoroughly. In this approach, the RF transmitter gain is determined automatically using a volume-selective power optimization and complemented with information from relative reception sensitivity maps derived from contrast minimized images to correct differences in transmission and reception sensitivity. In this way, a reliable measure of the local sensitivity was obtained. The proposed method is used to derive in vivo concentrations of brain metabolites and tissue water in two studies with different coil sets in a total of 40 healthy volunteers. Resulting molar concentrations are compared with results using internal water referencing (IWR) and Electric REference To access In vivo Concentrations (ERETIC). With the proposed method, changes in coil loading and regional sensitivity due to B1 inhomogeneities are successfully corrected, as demonstrated in phantom and in vivo measurements. For the tissue water content, coefficients of variation between 2% and 3.5% were obtained (0.6 1.4% in a single subject). The coefficients of variation of the three major metabolites ranged from 3.4-14.5%. In general, the derived concentrations agree well with values estimated with IWR. Hence, the presented method is a valuable alternative for IWR, without the need for additional hardware such as ERETIC and with potential advantages in diseased tissue. PMID- 29465822 TI - MSN-on-a-Chip: Cell-Based Screenings Made Possible on a Small-Molecule Microarray of Native Natural Products. AB - Standard small-molecule microarrays (SMMs) are not well-suited for cell-based screening assays. Of the few attempts made thus far to render SMMs cell compatible, all encountered major limitations. Here we report the first mesoporous silica nanoparticle (MSN)-on-a-chip platform capable of allowing high throughput cell-based screening to be conducted on SMMs. By making use of a glass surface on which hundreds of MSNs, each encapsulated with a different native natural product, were immobilized in spatially defined manner, followed by on chip mammalian cell growth and on-demand compound release, high-content screening was successfully carried out with readily available phenotypic detection methods. By combining this new MSN-on-a-chip system with small interfering RNA technology for the first time, we discovered that (+)-usniacin possesses synergistic inhibitory properties similar to those of olaparib (an FDA-approved drug) in BRCA1-knockdown cancer cells. PMID- 29465823 TI - Differential expression of various clones of estrogen receptor in cell block preparation of lung adenocarcinoma. AB - BACKGROUND: Women treated for breast cancer are at increased risk of developing pulmonary nodules which could represent new primary lung carcinomas or metastatic breast carcinoma. The FNA biopsy is frequently the first diagnostic choice in determining the primary site of the tumor. Estrogen receptor (ER) positivity in diagnostic tissue is generally used to favor breast over lung primary. However, the recent studies have shown a wide range of ER antibody cross reactivity with lung adenocarcinoma. We studied the frequency of ER expression in cytology samples of lung adenocarcinoma using antibodies to three different ER clones. METHODS: Cytology cell block preparations, including 22 lung FNAs and 19 malignant pleural effusions (PE) from 41 patients, with clinically documented primary lung adenocarcinomas were selected for this study. All cases were stained with monoclonal antibodies to ER clones 6F11 and 1D5. Twenty nine cases with remaining available material (15 FNA and 14 PE) were stained with a third antibody to ER clone SP1. The extent of ER nuclear staining was scored as 3+ (50% 100% of tumor cells), 2+ (11%-49%), and 1+ (<=10%). RESULTS: Positivity for ER 6F11 clone was present in 4 of 22 lung FNAs (18.2%, 2+ staining). Two of the four 6F11 positive FNAs also co-expressed ER-1D5 (9.1%, 2+ staining). No immunoreactivity was observed for ER clones 6F11 and 1D5 in all 19 malignant PEs. In addition, none of the remaining 15 FNAs and 14 PEs showed immunoreactivity for ER-SP1 clone. CONCLUSIONS: A small subset of pulmonary adenocarcinomas shows immunoreactivity for ER clones 6F11 and 1D5 in FNA samples (18.2% and 9.1%, respectively). The absence of immunoreactivity for ER-SP1 clone indicates higher specificity of this clone in non-breast tissue. The differential diagnostic value of all ER clones in malignant PEs appears to be secure. Larger studies are necessary to validate this observation. PMID- 29465824 TI - Left ventricular chamber geometry in cardiomyopathies: insights from a computerized anatomical study. AB - AIMS: Some authors have hypothesized that left ventricular chamber dilatation in ischaemic and idiopathic cardiomyopathies results in spherical transformation. Aiming to characterize how this transformation occurs, a study was performed by comparing normal and dilated specimens regarding sphericity and proportionality in left heart chambers. It is important to provide data for the development of therapeutic strategies in these diseases. METHODS AND RESULTS: An anatomical study was performed by comparing normal (n = 10), ischaemic (n = 15), and idiopathic (n = 18) dilated human cardiomyopathic specimens regarding left ventricular chambers and their segmental proportionality to normal hearts. It was performed by capturing and processing images with proper software in three different levels of left ventricular chamber (basal, equatorial, and apical). These obtained data were analysed based on sphericity and proportionality by two dedicated indexes. Spherical shape: Calculated segmental indexes showed that dilated specimens were not spherical because they were smaller than as expected for a spherical shape (all values were <70% of a perfect sphere). Proportionality: There was no difference between basal index perimeters among groups, but apical index was lower in dilated specimens than in normal hearts, and so dilatation was not proportional to normal hearts. CONCLUSIONS: Left ventricular chambers of anatomical specimens with dilated cardiomyopathies did not display a spherical shape and were not proportional to normal hearts.

AB - Safe and rechargeable lithium metal batteries have been difficult to achieve because of the formation of lithium dendrites. Herein an emerging electrolyte based on a simple solvation strategy is proposed for highly stable lithium metal anodes in both coin and pouch cells. Fluoroethylene carbonate (FEC) and lithium nitrate (LiNO3 ) were concurrently introduced into an electrolyte, thus altering the solvation sheath of lithium ions, and forming a uniform solid electrolyte interphase (SEI), with an abundance of LiF and LiNx Oy on a working lithium metal anode with dendrite-free lithium deposition. Ultrahigh Coulombic efficiency (99.96 %) and long lifespans (1000 cycles) were achieved when the FEC/LiNO3 electrolyte was applied in working batteries. The solvation chemistry of electrolyte was further explored by molecular dynamics simulations and first principles calculations. This work provides insight into understanding the critical role of the solvation of lithium ions in forming the SEI and delivering an effective route to optimize electrolytes for safe lithium metal batteries.

AB - Recently, most of evidence shows that caloric restriction could induce antidepressant-like effects in animal model of depression. Based on studies of the brain-gut axis, some signal pathways were common between the control of caloric restriction and depression. However, the specific mechanism of the antidepressant-like effects induced by caloric restriction remains unclear. Therefore, in this article, we summarized clinical and experimental studies of caloric restriction on depression. This review may provide a new therapeutic strategy for depression. PMID- 29465829 TI - [Spatio-temporal variation of the ichthyofauna in Xel-Ha, Mexican Caribbean Marine Park and its relationship to physico-chemical parameters]. AB - Xel-Ha is a private marine park where the extraction of flora and fauna is not allowed. Here, reef fish are one of the main touristic attractions, but there are no published surveys focused on fish community in this site. In this study we analyzed the spatio-temporal variation of the fish community in different areas of the marine park Xel-Ha. Abundance and richness were estimated during one-year period (2012-2013); visual censuses using fixed transects of 100x5 m each distributed in 21 transects along five sites were established in different zones: "Bocana", "Center", "North branch", "Cave" and "River", including the inlet mouth to the sea, brackish mangrove channels and a zone with freshwater influence. To characterize the fish community, we used species richness, abundance, diversity, and density compared among zones and climatic seasons (rain, "norths" and dry). The similarity among zones and seasons was estimated using a multidimensional scaling analysis. The replacement on the species composition among seasons and sites was realized based on the presence-absence of fish. The influence of physicochemical variables such as temperature, salinity and dissolve oxygen concentration in the fish community was estimated by a principal component analysis. A total of 22 641 individuals were recorded corresponding to sixty three species over the year. Abundance was higher during the windy season (locally named "norths") with 7 991 organisms. The most representative species according with abundance and frequency of occurrence were: Haemulon sciurus, H. flavolineatum, Lutjanus griseus, Acanthurus coeruleus, Abudefduf saxatilis, and Gerres cinereus. Diversity increased from the rainy to the dry season; species richness and diversity was lower in "River" than other sites in Xel-Ha. Most species (54 %) species were residents through the year. Four non-shared species were observed during the rainy season and three in dry season. Dissolved oxygen was the most influential variable on the fish community composition among zones. Xel-Ha houses nearly 20 % of fish biodiversity reported for the mexican Caribbean, and the predominance of juveniles of several species confirms its role as a nursery area.

PMID- 29465830 TI - Toll-like receptor 3 signal augments radiation-induced tumor growth retardation in a murine model. AB - Radiotherapy induces anti-tumor immunity by induction of tumor antigens and damage-associated molecular patterns (DAMP). DNA, a representative DAMP in radiotherapy, activates the stimulator of interferon genes (STING) pathway which enhances the immune response. However, the immune response does not always parallel the inflammation associated with radiotherapy. This lack of correspondence may, in part, explain the radiation-resistance of tumors. Additive immunotherapy is expected to revive tumor-specific CTL facilitating radiation resistant tumor shrinkage. Herein pre-administration of the double-stranded RNA, polyinosinic-polycytidylic acid (polyI:C), in conjunction with radiotherapy, was shown to foster tumor suppression in mice bearing radioresistant, ovalbumin expressing Lewis lung carcinoma (LLC). Extrinsic injection of tumor antigen was not required for tumor suppression. No STING- and CTL-response was induced by radiation in the implant tumor. PolyI:C was more effective for induction of tumor growth retardation at 1 day before radiation than at post-treatment. PolyI:C targeted Toll-like receptor 3 with minimal effect on the mitochondrial antiviral signaling protein pathway. Likewise, the STING pathway barely contributed to LLC tumor suppression. PolyI:C primed antigen-presenting dendritic cells in draining lymph nodes to induce proliferation of antigen-specific CTL. By combination therapy, CTL efficiently infiltrated into tumors with upregulation of relevant chemokine transcripts. Batf3-positive DC and CD8+ T cells were essential for therapeutic efficacy. Furthermore, polyI:C was shown to stimulate tumor associated macrophages and release tumor necrosis factor alpha, which acted on tumor cells and increased sensitivity to radiation. Hence, polyI:C treatment prior to radiotherapy potentially induces tumor suppression by boosting CTL dependent and macrophage-mediated anti-tumor responses. Eventually, polyI:C and radiotherapy in combination would be a promising therapeutic strategy for radiation-resistant tumors.

PMID- 29465834 TI - Targeted Delivery of an Activatable Fluorescent Probe for the Detection of Furin Activity in Living Cells. AB - Furin, a protein convertase, plays a crucial role in the progression of tumors. In this work, a new fluorescent probe consisting of a peptide, Arg-Val-Arg-Arg (RVRR), and an aminoluciferin fluorophore was designed and prepared for the responsive and activatable detection of furin activity in vitro and in living cells. We demonstrated that this probe could be responsive toward furin with an "off-on" florescence signal and generated an approximately 3.58-fold enhancement in the fluorescence intensity in vitro. Fluorescence imaging in MDA-MB-468 and LoVo cells showed that the probe could be cleaved by overexpressed furin with fluorescence turn-on in MDA-MB-468 cells, and this probe was also found to be capable of discriminating between furin-overexpressing and furin-deficient cell lines. Our research indicates that this probe has great potential for the detection of furin activity in living cells.

AB - Diabetic retinopathy is a significant complication of diabetes, and the most common cause of blindness in people under the age of 65. The National Diabetic Retinal Screening Programme (Diabetic RetinaScreen) was established to detect sight threatening retinopathies. The purpose of this cross-sectional study is to determine the barriers to the uptake of Diabetic RetinaScreen, to investigate discrepancies in attendance, if any, between patients whose diabetes care is delivered in a large tertiary referral hospital out-patient setting or in general practice, and to evaluate general practitioner's satisfaction with the service. Older age (OR 1.023, 95% CI 1.001 to 1.046) and complications of diabetes, excluding ocular complications, (OR 2.741, 95% CI 1.158 to 6.489) were associated with increased attendance at Diabetic RetinaScreen. Online referral is now available and the preferred method of referral. Efforts to encourage younger patients who do not yet have complications of diabetes may be beneficial. PMID- 29465838 TI - An Analysis of Gender Diversity in Urology in the UK and Ireland. AB - Traditionally, surgery and certain surgical sub-specialities in particular have been predominantly male orientated. In recent years, there has been an increased proportion of female medical graduates which will ultimately have an effect on speciality choices. The aim of this study was to assess the gender diversity among urologists in the UK and Ireland. The total number and gender breakdown of consultant urologists and trainees in the UK and Ireland was obtained from the British Association of Urological Surgeons (BAUS) and the Irish Society of Urology (ISU) membership offices. The total number and gender breakdown of medical school entrants and graduates in 2015 was obtained from the six medical schools in the Republic of Ireland. There are a total of 1,012 consultant urologists in the UK and Ireland. In the UK, 141 (14.6%) are female compared to four (8.2%) in Ireland, p= 0.531. There was a significant increase in the number of females between consultant urologists and trainees in both the UK (p=0.0001) and Ireland (p=0.015). In recent years, there has been a significant change in the percentage of female trainees in the UK and Ireland (22.8% (n=75) in 2011 vs 31.7% (n=93) in 2014, p=0.019. Between the six medical schools in Ireland, there were significantly more female entrants (n=726, 56.5%) than female graduates (n=521, 51.2%) in 2015, p=0.013.There has been a significant shift in gender diversity in urology in the UK and Ireland. Efforts to increase diversity should be pursued to attract further trainees to urology. PMID- 29465839 TI - Vitamin D Insufficiency in Patients Undergoing Total Knee Arthroplasty in Ireland. AB - Introduction: Vitamin D is essential for bone health. We aimed to assess the vitamin D levels of patients undergoing total knee arthroplasty TKA). Methods: All TKA patients during a calendar year had their 25-hydroxyvitamin-D3 (25-OH-D3) assay levels assessed pre and post operatively. A control group comprising of patients admitted for 1-day general medical assessment was recruited. Usage of supplements containing Vitamin D was recorded for both groups. Results: There was no evidence of a difference in Vitamin D levels between the TKA group and the control group (p=0.19). Just over 40% of patients had insufficient levels of vitamin D in the TKA group (50 nmol/L cut off). There was a statistically significant drop in vitamin D levels post operatively (p=0.0001). Supplements were protective against insufficiency post operatively (p=0.0005, OR 6.0985). Discussion: This study documents a high prevalence of vitamin D insufficiency in patients undergoing TKA surgery. Our results suggest a consumption of 25-OH-D3 as part of the surgical insult.

No clear association could be established between PSF, social, radiological and functional characteristics. PMID- 29465841 TI - Permanent Childhood Hearing Impairment: Aetiological Evaluation of Infants identified through the Irish Newborn Hearing Screening Programme. AB - The Newborn Hearing Screening Programme (NHSP) was established in Cork University Maternity Hospital (CUMH) in April 2011. Between April 2011 and July 2014, 42 infants were identified with a Permanent Childhood Hearing Impairment (PCHI). Following this diagnosis, infants underwent a paediatric assessment according to recognised guidelines with the intention of identifying the underlying aetiology of the PCHI. The aim of this study was to assess the findings of this aetiological workup via retrospective chart review. PCHI data was obtained from the eSP database. This is a web based information system (eSP) used to track each baby through the screening and referral process A retrospective chart review of these patients was performed. Sixteen (38%) infants were diagnosed with a bilateral sensorineural hearing loss. Two infants had congenital CMV infection. A Connexin 26 gene mutation was detected in one infant. Two infants were diagnosed with Waardenburg syndrome, One with Pendred syndrome and one with Pfeiffer syndrome. Five babies underwent cochlear implantation. Through adherence to the recommended protocol a possible cause of PCHI may be determined. This study has identified areas of future improvement for this service in Ireland. PMID- 29465842 TI - Paediatric Consultation Liaison Psychiatry Services (PCLPS) -what are they actually doing? AB - Introduction Paediatric Consultation Liaison Psychiatry Services (PCLPS) are specialised services treating mental health difficulties co-morbid with medical problems. Methods Standardised clinical data was retrieved from all case notes (N=108) during the study timeframe (Jan-June 2016). Results The majority of children were female 59 (55%) with a mean age of 13. Presentation was typically via the Emergency Department (ED) (85, 79%), and of those, the majority (53, 62%) were 'out of hours' and for Deliberate Self-harm (44, 52%) Almost half of all cases seen (50, 46%) were previously known, and discharged back (84, 78%), to CAMHS. Discussion The majority of work conducted by the PCLPS involved children with acute or deteriorating psychiatry disorders, previously known to CAMHS, with a much smaller focus on typical liaison presentations. Adequate resourcing of hospital based PCLPS and 'out of hours' CAMHS are necessary to allow PCLPS provide a specialist service to children with combined medical and MH problems. Given the development of the National Children's Hospital, addressing these resourcing deficits is of vital importance. PMID- 29465843 TI - Awareness of Medical Fitness to Drive Guidelines among Occupational Physicians and Psychiatrists. AB - Irrespective of national guidelines for medical fitness to drive, this study investigated the cumulative expert wisdom of clinicians regarding minimum periods of driving cessation required for patients suffering from conditions that can impair driver capability. Occupational Physicians (196) and Psychiatrists (103) completed an online questionnaire. For private motorists, the modal response for anxiety and depression favoured clinical discretion, followed by three month cessations for hypomania, acute psychosis, schizophrenia and alcohol dependence and six weeks for alcohol misuse/dependence. For professional drivers the modal value for anxiety and depression was three months, rising to six months for hypomania, psychosis and schizophrenia and 12 months for both alcohol misuse/dependence. Chi-square test results indicated statistically significant differences in clinical opinion between Occupational Physicians and Psychiatrists regarding driving cessation times for drivers suffering from psychiatric and alcohol misuse conditions except for alcohol dependence. Further studies are warranted to investigate these issues in more depth. PMID- 29465844 TI - Oocyte Donation Pregnancies- Non-Disclosure of Oocyte Recipient Status to Obstetric Care Providers and Perinatal Outcomes. AB - Background: Oocyte donation pregnancies- non-disclosure of oocyte recipient (OR) status to obstetric care providers and perinatal outcomes.Many studies report a higher rate of pregnancy-induced hypertension (PIH) and severe pre-eclampsia (PET) in OR pregnancies. The objective is to determine the rates of non disclosure of OR pregnancy to obstetric care providers and also the rates of perinatal complications. Method: This was a retrospective review of all oocyte recipient (OR) pregnancies, who subsequently delivered at Cork University Maternity Hospital, between 2007- 2012 inclusive. Obstetric case notes were reviewed to investigate perinatal outcomes and whether OR status had been documented (unambiguously, in code or not at all). Results: Less than one-third (30.2%; n=32/106) had unambiguous documentation, one-third (33%; n=35/106) had no documentation and the remainder (36.8%; n=39/106) had a code familiar only to their obstetrician. There was a high rate of gestational hypertensive disorders (28.3%; n= 30), most frequently occurring with multiple gestation. Discussion: There was a low rate of clear documentation of OR status. Gestational hypertensive disorders occurred with increased frequency. PMID- 29465845 TI - A Study To Assess The Prevalence Of Exercise-Induced Bronchoconstriction In Inter County Hurling. AB - Exercise-Induced Bronchoconstriction (EIB) is an acute, transient airway narrowing occurring after exercise which may impact athletic performance. Studies report 10% of the general population and up to 90% of asthmatics experience EIB. Ninety-two players from three elite hurling squads underwent a spirometric field based provocation test with real-time heart rate monitoring and lactate measurements to ensure adequate exertion. Players with a new diagnosis of EIB and those with a negative field-test but with a previous label of EIB or asthma underwent further reversibility testing and if negative, methacholine challenge. Eight (8.7%) of players had EIB, with one further athlete having asthma with a negative field test. Interestingly, only three out of 12 players who had previously been physician-labelled with EIB or asthma had their diagnosis objectively confirmed. Our study highlights the role of objective testing in EIB. PMID- 29465846 TI - Isolated Unilateral Pulmonary Artery Agenesis complicated by Symptomatic Aspergilloma.

AB - Accidental self-inflicted knife injuries to digits are a common cause of tendon and nerve injury requiring hand surgery. There has been an apparent increase in avocado related hand injuries. Classically, the patients hold the avocado in their non-dominant hand while using a knife to cut/peel the fruit with their dominant hand. The mechanism of injury is usually a stabbing injury to the non dominant hand as the knife slips past the stone, through the soft avocado fruit. Despite their apparent increased incidence, we could not find any cases in the literature which describe the "avocado hand". We present a case of a 32-year-old woman who sustained a significant hand injury while preparing an avocado. She required exploration and repair of a digital nerve under regional anaesthesia and has since made a full recovery. PMID- 29465849 TI - Interventions to Improve the Treatment of Malaria in an Acute Teaching Hospital in Ireland. AB - Malaria is the most serious parasitic infection. At our institution over a two year period there were treatment errors in 18% (n=3) of cases. The aim of this multidisciplinary study was to ensure appropriate and timely treatment of malaria by implementation of a cluster of interventions: reconfiguration of existing guidelines, provision of prescribing information; delivery of education sessions to front-line staff and enabling rapid access to medication. Staff feedback was assessed through a questionnaire. Perceived benefits gained included awareness of guidelines (91%, n= 39), how to diagnose (81%, n =35), how to treat (86%, n=37), that treatment must be prompt (77%, n=33) and where to find treatment out of hours (84%, n=36). 'Others' perceived benefits (5% n= 2) noted referred to treatment in pregnancy. Going forward, a programme of on-going staff education, repeated audits of guideline compliance and promotion of reporting of medication errors should help ensure that these benefits are sustained. PMID- 29465850 TI - Incorporating Oral Health as Part of Routine Diabetes Care in Ireland. AB - Diabetes mellitus is a common disorder of glucose metabolism that is increasingly prevalent in the Irish population. It is associated with a range of complications leading to substantial morbidity and mortality. A less well-recognized complication of diabetes is periodontal disease. This is a chronic inflammatory disease affecting the periodontium, the specialized group of tissues that surround and support the teeth, including the gingiva (gums) and alveolar bone. Periodontal disease affects patients with diabetes with a greater prevalence and incidence than non-diabetic patients, and can itself exert negative effects on glucose control in people with diabetes. The National Clinical Programme for Diabetes in Ireland aims to reduce the morbidity and mortality associated with diabetes, which includes the development and dissemination of guidelines supporting integrated care. Based on the bidirectional relationship between diabetes mellitus and periodontal disease, we recommend that an oral health evaluation, as well as any necessary onward referral, be incorporated into the Irish recommendations for routine diabetes care, as part of the National Clinical Programme.

AB - BACKGROUND: The first Ebola virus disease (EVD) epidemic in West Africa is unprecedented in its spread, complexity and severity. Comparing responses to spread of the virus in the three most affected countries - Guinea, Sierra Leone and Liberia- with that in Nigeria, Senegal and Mali where the epidemic was quickly brought under control may guide future mitigation efforts. METHODS: Literature from Pubmed. Google,Center for Disease Control and Prevention (CDC), Morbidity and Mortality Weekly Report (MMWR), World Health Organization's Updates and Ebola Response Reports: Results: The epidemic spread undiagnosed for three months from Meliandou in Guinea to its four rural prefectures and its. capital Conakry, two countires in Liberia and two districts in Sierra Leone. Control measures were hampered by traditional and faith healers offering -inappropriate treatments, as well as secret societies encouraging unsafe burial rituals. Whereas, in Nigeria, a case imported from Liberia on 20 July 2014 was diagnosed on the 3rd day; all primary, secondary and tertiary contacts were traced. Also, at a formal meeting, officials of Lagos state government discouraged treatment of EVD by faith healers. In Senegal, a single case imported from Guinea on 20 August 2014 was diagnosed on the 9th day, treated and further spread was prevented. In Mali, there were two waves of transmissions identified on 23 October and 12 November 2014 within 15 days of importation and the epidemic was controlled.There were no cases of EVD treated by any traditional healers or faith healers in Nigeria, Senegal and Mali. CONCLUSION: Education of traditional and faith healers on EVD will complement control measures for EVD epidemic. PMID- 29465856 TI - Bacteriology of middle meatal aspirate of adult patients with chronic rhinosinusitis in Lagos. University Teaching Hospital, Lagos. AB - BACKGROUND: Chronic rhinosinusitis (CRS) significantly lowers the quality of life of patients. The common use of broad spectrum antibiotics for its treatment may alter the pathogens that promote the persistence of this condition. However, the data concerning the distribution of bacteria species. in patients with CRS are not consistent. OBJECTIVE: To isolate the common aerobic and anaerobic bacteria from the middle meatal aspirates of adult patients with CRS and determine their antibiotic sensitivity patterns Methods: This was a case-control study of adults with diagnosis of CRS. Middle meatal aspirate and swab were obtained from cases and control respectively for bacteriological studies. Data analysis was done using Statistical package for social sciences (SPSS) version 17 Result: Forty one aerobic bacteria were cultured. Sixty one percent of the aerobic bacteria isolated were gram positive (staphlylococcus.aureus was the most frequently found) organisms while the remaining 39% was gram negative. Fifteen peicent of the cultured isolates yielded mixed growth of both aerobes (Gram positive and gram negative).3(6%) isolates of Bacteroides species were cultured Conclusion: The present study found that Staphylococcus aureus, streptococcus pneumoniae, Proteus mirabilis, Klebsiella spp, Escherichia coli and Bacteroides spp) were the common bacterial flora in the paranasal sinuses of patients with CRS. PMID- 29465857 TI - Dental care seeking behaviour of children in a rural Nigerian community. AB - BACKGROUND: There is sparse information about oral health seeking behaviour of children in rural areas of developing countries. The aim of the Study was to determine the dental care seeking-behaviour of children attending the first rural based community oral health centre in Nigeria. METHODS: A retrospective review of records of patients aged 16 years or younger treated at the Primary Oral Health Care Centre in Ibarapa, Nigeria over six years was conducted. Data on sociodemographic characteristics of the patients, pattern of presentation and their oral hygiene practices were collected and processed using SPSS. RESULTS: A total of 239 paediatric patients were seen during the period with a mean age of 9.7 +/- 4.4 years and 132 (55.2%) were males. The majority, 225 (94.1%), were presenting for the first time. All the children sought dental care for one problem or the other and the most common reasons for seeking care were: tooth ache in 105 (43.9%), trauma in 30 (12.6%) and perceived unclean mouth in 20 (8.4%) patients. Older children were more likely to seek dental care because of pain (p < 0.00 1), while younger children sought care principally on account of trauma (p < 0.001) and the under 5 years were seen more often for gum ache (p =0.006). The majority, 175 (73.2%), used toothbrush and 182 (76.2%) cleaned their teeth once daily. CONCLUSION: None of the children presented for routine check up, rather, consultation was as a result of dental problems with toothache being the most common reason.

AB - OBJECTIVE: This study was carried out to explore perceptions ofunder five caregivers on growth monitoring in Ibadan south-west local government in Nigeria. METHOD: Descriptive. cross-sectional-design was used for the study which involved four-stage sampling techniques. The study was conducted among the 410 caregivers who consented to participate. Both qualitative and quantitative methods were used to collect the data. The questionnaire elicited information on sociodemographic characteristics, Knowledge, Attitude and Growth -Monitoring perceptions were measured on a 16-point scale and categorizedinto "negative" (<=8) and positive (>8) Descriptive statistics -using mean and standard deviation were generated while qualitative data was analysed using Atlas Ti version 7. Result Mean age of the Caregivers of Under-5 was 31.6+/-6.5 years, 46.8% had secondary education and 56.8% were traders. Majority (88.3%) had received information on Growth Monitoring and (66:6%) heard from the health workers. Almost all the: respondents (90.0%) had positive perception towards Growth Monitoring (10.8+/-2.9). It was also suggested by the caregivers that their involvement is very crucial in monitoring the growth of their children. Concusion: The study showed that most of the caregivers. had positive perceptions towards growth monitoring and advocated their active involvement if training progriammes can be developed. PMID- 29465859 TI - Spectrophotometric studies of a novel Gedunin-2-Hydroxypropyl- beta-cyclodextrin binary system. AB - BACKGROUND: Gedunin, a limonoid, is linked with antimalarial, anticancer and anti allergic activities. This study was aimed at preparing an inclusion complex of gedunin and 2-hydroxypropyl-p-cyclodextrin (HBD) to increase solubility of gedunin in polar solvents which will increase absorption and bioavailability in vivo and thus enhance pharmacological effects. MATERIALS AND METHODS: Gedunin was obtained from the hexane extract of Entandrophragma angolense heartwood by column and preparative thin layer chromatography. The structure was previously confirmed by spectroscopic means (NMR). The electronic absorption spectra data of the complexes formed between gedunin. and HBD in various solvents was determined using the UV-VIS spectrophotometer. The stoichiometry of inclusion was determined by Job's method of continuous variation. RESULTS: Evidence of interaction was observed between gedunin and HBD in the various solvents but gedunin and its complex with HBD exhibited sharp absorption bands in acetate buffer (pH 3.5).The spectrophotometric titrations showed curves with a single point of inflexion when the experiment was carried'out at 250C (298 K) and 370C (310 K). A stoichiometric ratio of 1:1 for complex formation was obtained. The formation constants (K,) obtained at 250C and 370C.were 9.539 x.103 M-1 and .1.853 x 104 M-1 respectively. Thermodynamic considerations revealed hydrophobic interaction between gedunin and HBD. CONCLUSION: A stable inclusion complex of gedunin and HBD was formed at room and body temperature. This complex formation involved trapping of poorly soluble gedunin into the hydrophobic core of the cyclodextrin and may enhance the pharmacological activity of gedunin in vivo. PMID- 29465860 TI - Sport participation and injuries among undergraduate students of a Nigerian University. AB - : Backgroud: Sports participation is a healthy behaviour but it is not without the risk of injuries. Information on the extent of sport participation and sport injuries among Nigerian Unversity students is sparse. Objeclive: To determine the prevalence and types of sport participation and injuries among university.students in Nigeria. Factors associated with sport participation among students were also examined. METHODS: A cross-sectional survey was conducted using a self-administered questionnaire to collect information on the frequcncy and types of sport participation and sport-related injuries among a representative sample of undergraduate students of the University of Lagos, Nigeria. Resuts: A sport participation prevalence of 64.2% (95%CI: 59.5 - 68.7) was recorded among students. Football (soccer) (53.2%) had the highest participation rate. Male students (78.4% vs.41.2%) participated more frequently in sports (p <0.001). Overall injury rate was 52.5 injuries/100 students/ year (95%CI: 46.5 - 58.5). The prevalence of injury was 45.7% in male and 12.7% in female students. About half (49.3%) of reported injuries resulted in time loss. The leg and ankle were the most frequently injured body parts for all injuries and most serious injuries. Football recorded the highest prevalence of injury (73.8%). CONCLUSION: Sport participation among students was fair and injury rate was considerably high, mostly affecting the lower extremity and most injuries resulting from football participation. This study suggests the need for improved sport participation support among students and the need for the initiation of injury prevention initiatives by stakeholders. PMID- 29465861 TI - A prospective study of adverse events to antiretroviral therapy in HIV- infected adults in Ekiti State, Nigeria. AB - OBJECTIVES: Highly active antiretroviral therapy (HAART); the-current standard of antiretroviral therapy for Human Immunodeficiency Virus (HIV) infected persons, has been documented to drastically, reduce the number of cases of Acquired Immune Deficiency Sypdrome (AIDS). However, adverse. events are a challenge to the use of HAART. This study intends to determine the nature and incidence of suspected advcrse events to prescribed anti retroviral drugs in treatment centers in Ekiti State. METHOD: One hundred and twenty participants were enrolled and followed up over a period of six months. At each clinic visit, there was an administration of a detailed interviewer questionnaire that was completed by the attending pharmacist together with the participant. The form is designed to obtain information on the demographics of the patients, WHO clinical stage of their HIV infection, HAART regimen for the patients, and suspected adverse events associated with the antiretroviral drugs used by the patients. RESULTS: Tenofovir/Lamivudine/Eifavirenz (72.5%), Zidovudinc/Lamiv.udin/Nevirapine (16.7%), Zidovudine/Lamivudiine/ElafIvirenz (6.7%), Tenofovir/ Lamivudine/Nevirapine (3.3%), and Abacavir/ Lamivudine/Nevirapine (0.8%) were the HAART regimens prescribed to the patients. About half (57%) of the participants reported clinical adverse events; 92% of which were reported within two weeks of HAART initiation. Most of the reported adveise events were nausea (14.5%), abdominal discomfort (8.2%), and insomnia (7.5%). A few (6%) of those who reported adverse events required regimen switch or drug substitution. CONCLUSIONS: Antiretroviral drugs exposure often presents with adverse events, an observation similar to other studies. Most of the clinical adverse events were not severe or life threatening. PMID- 29465862 TI - Validation of a Yoruba version of the arthritis self-efficacy scale. AB - BACKGROUND: The Arthritis Self Efficacy Scale (ASES) measures a patient's perceived efficacy to cope with the consequences of chronic arthritis. The aim of this, study was to translate ASES in to Yoruba, one of the indigenous Nigerian languages, and to investigate the validity and reliability of the translated version. METHODS: Forty one (21 males; 20 females).patients diagnosed with arthritis participated in this cross sectional survey, although only thirty seven (87.8%) were available for the reliability study. The ASES was translated to Yoruba language using forward-backward translations. Participants completed both English and Yoruba version of ASES on the first day while the second administration of the two versions of ASES was.. completed at one week after the first administrations. Data was analyzed -using descriptive statistics, Spearman correlation and intra-class correlation (at p=0.05). RESULTS: There was a significant direct correlation (p<0.0001) between the scores obtained on the English and Yoruba versions (r=0.933). Also there was a significant direct correlation (p<0.0001) between the scores obtained on the first and second administrations of the English and Yoruba version of the ASES. CONCLUSION: The Yoruba version of the ASES is a valid and reliable outcome measure for health outcomes assessment in Yoruba-speaking populations. PMID- 29465863 TI - Methods of voluntary reporting medication administration errors among nurses in the University College Hospital, Ibadan, Nigeria. AB - BACKGROUND: Reporting medication administration error (MAEs) is a significant strategy to ensure patient safety. Literature had it that most of what is reported as errors of administration is just a tip of the iceberg, suggesting that a lot more go unreported. The methods of reporting medication administration errors in Nigeria have not been well explored. This study examined the methods of reporting MAEs by nurses in selected wards. in the University College Hospital, Ibadan. Nigeria. Methods- A cross sectional survey of 286 nurses, who were conveniently selected from Medical, Surgical and Accident and Emergency departments of the University College Hospital, Ibadan Nurses who gave consent to participate completed a 42-item structured questionnaire on the methods and reasons for non-reporting MAEs. RESULTS: Among the study cohort, 162(64.8%) admitted to have committed MAEs in the past, of which 137(84.4%) voluntarily reported. Common methods included reporting to inmmediate supervisor (88; 34%), and confiding in a colleague 62 (24.8%). Only 39 (15.6%) documented and completed report forms. In addition, 183 (73.2%) believed that anonymous reporting enhances the rate of reporting errors. The major reason for non-reporting was the fear of being punished and labelled as incompetent practitioner (Mean 3.82, +/- 1.09). CONCLUSION: Findings suggest that not all MAEs committed by the study cohort were reported, and the methods used differ with individuals and units of practice. There is therefore a need to create more awareness that disclosure of MAEs will help to identify the specific causes of errors, thereby fostering safe practice. PMID- 29465864 TI - Endodontic flare up: incidence and association of possible risk factors. AB - BACKGROUND: Endodontic emergency during root canal treatment (flare up) is a common occurrence in multivisit root canal treatment (RCT) and it may be associated with many factors. The occurrence however can affect the prognosis of the tooth and the patient -clinician relationship. AIM: To determine the incidence and risk factors associated with occurrence of flare up in a multi visit RCT. METHODOLOGY: Patients planned for multi-visit (RCT) were recruited for the research. Standard protocol was followed in all cases. After the first visit, the patients were followed up for possible development of flare up. Patients' demographics, presence or absence of preoperative pain, status of the pulp and occurrence of flare up were among the data collected. Data was analyzed using SPSS version 20 with level of significance set at P <0.05. RESULT: A total of 106 root treated teeth were analyzed in patients aged 17 to 73years with a mean of 33+/-13.2 and male to female ratio of 1:1.5. Incidence of flare up was 8.5%. Prior to treatment, 47% of the cases had pain, 61.3% had apical radioluscency and 83% had pulpal necrosis. Majority (7, 77.8%) of the flare up occurred after the first visit (p=0.000). Only pre- treatment pain had a statistical significant ielationship with occurrence of flare up (p=0.009). CONCLUSION: Incidence of flare up was 8.5% and the major risk factor was preoperative pain. First visit in a multi visit RCT is an important stage which if well handled, can reduce the incidence of flare up. PMID- 29465865 TI - Nicolo Paganini's hair lock for Signora Chatterton - morphological hair investigations using digital light microscopy. AB - The famous violin virtuoso Nicolo Paganini (born on 27 October 1782 in Genoa, died on 27 May 1840 in Nice) left us with many puzzles. An interesting aspect is his hair: In the 19th century, hair given away as a token of friendship or romantic love became very popular, and Paganini also seems to have made use of this fad. In 2009, a lock of hair, purportedly that of Paganini, kept in a locked presentation box together with a bilingual autograph inscription saying: "Alla Signora Chatterton avec les compliments de Nicolo Paganini" was bought at an auction. From this hair lock a sample was taken and was investigated morphologically by using digital light microscopy (digital microscope VHX-100, Keyence) in reflected and transmitted light with and without polarization at different magnifications up to 1:5,000. The sample was then compared with a hair sample from the possession of the Paganini family, which had been microscopically examined in 2012 by the co-author of this paper yielding numerous figures with measurement results that had been stored and could be retrieved for direct comparison. The hair sample consisted of ten strands of hair or hair fragments and was investigated with great effort for the following parameters: exogenous hair damage, especially feeding traces caused by parasites, modeling and angulation of hairs, hair thickness, medulla and pigmentation, curling and mercury load on the trace material. After evaluation of all findings not only a non-exclusion of identity can be determined, but due to the broad match of also rare findings there is no reasonable doubt about their identity. In addition, the findings suggest that the studied hair samples are in fact from Paganini's head. The present case of Nicolo Paganini's hair lock is also an excellent starting point for reflections on the probative value of trace hair investigations. This point is also critically discussed in the paper. Finally, this study shows that said lock of hair had probably really been dedicated and given to Eliza Davenport Latham (born on 25 November 1806, died on 9 January 1877), the future wife of the, at that time, best-known and most famous English harpist John Balsir Chatterton (born on 25 November 1804, died on 9 April 1871). Paganini must have met her on his concert tour 1831/32, where he had travelled to Paris, London, the rest of England, Scotland and Ireland. PMID- 29465866 TI - Field study to detect illicit and medicinal drugs in car drivers in Southern and Western Hesse. AB - In the present study, immunochemical tests (Mahsan DrugInspector, DOA4, DOA8, DOA10, Protzek) as well as the detection rate of police checks were evaluated. Urine and blood samples of suspected car drivers were analysed by chromatography mass spectrometry. Additionally, anonymised urine samples were analysed on a voluntary basis in cases where no legal proceedings were initiated. Toxicological analyses (total unknown screening) were performed using gas chromatography-mass spectrometry (GC-MS) after hydrolysis, acidic and alkaline extraction and derivatization. A data base for screening 9000 substance entries was applied. In addition, urine samples were analysed using liquid chromatography/ time-of-flight mass spectrometry (HPLC-ToF-MS) to screen psychiatric and narcotic drugs. In total, samples of 154 suspects were analysed, of these, 46 samples for no actual reason. In 5 of the latter samples, forensically relevant substances were detected; in two cases the consumption of illicit drugs, i. e. cannabis and methamphetamine, was proved. Of the 154 suspects, 108 were charged with driving under the influence of drugs; in samples of 103 of these cases, illicit drugs were found. Immunochemical pretesting showed posi- tive results in 97 of the 108 cases; in 6 samples, psychiatric drugs (citalopram, doxepin, promethazine, mirtazapine, fluoxetine, venlafaxine) were later identified, which are not detectable by ordinary pretesting systems. Police officers successfully identified 95.4 % of the suspects as drug consumers, which is an excellent result. In practice, pretesting of urine samples using immunochemical techniques proved to be very reliable. The Protzek system in particular corresponded well with the results of the chromatographic analyses. In conclusion, systematic chromatographic-mass spectrometric analysis of urine samples of suspects is recommended to identify car drivers consuming illicit drugs and to obtain data usable in legal proceedings (e. g. suspending of the driving license), which is not always possible when using blood samples in cases of drugs consumed some time ago. PMID- 29465867 TI - Lethal hypothermia after firing a suicidal shot to the head in a car. AB - In suicide cases involving an automobile, the car is mostly used as a tool/instrument for the suicide (intoxication by exhaust fumes, crash against solid objects such as a pylon). However, a car is uncommonly also used only as the location for a suicide. In the present case, a 70-year-old man had been found dead on the passenger seat of his car. According to witnesses, the car had not been parked there at the same time of the previous day. During that period, the weather had been dry, with temperatures ranging from -10 C at night to +50 C during the day. The man had shot himself with a small-caliber revolver (so-called bulldog-revolver) almost horizontally in the left temple (transtemporal shot through the frontal lobes). Obviously, the suicide had retained the capability to act at least for a short time, as the revolver was found under his left bottom. As morphological signs of prolonged agony some findings of hypothermia were observed (e. g. Wischnewski spots of the stomach). PMID- 29465868 TI - Quality of death certificates in hospitals. AB - The cause-of-death-statistics and the release of the body for burial depend primarily on the information contained in the death certificate. How to handle the death certificate has been critically discussed in professional circles again and again. A retrospective review of 1,315 deaths from six acute care hospitals in Germany was carried out with regard to the quality of the death certificates, taking into account information contained in the medical records. The review covered the readability of the death certificate, the quality of the epicrisis, misclassifications relating to the manner of death and the degree of certainty regarding the cause of death. In 93 % of cases (n= 1,221), death certificates were clearly legible. In about half the cases (43.3 %, n=569), the quality of the entries in the "epicrisis" section was good. In 45 % of cases (n= 592), no details were provided in the "epicrisis " section. In 3.9 % (n = 42) of deaths classified as natural, information was given indicating a non-natural death. Most of these deaths occurred in connection with a fall or an injury (n = 27) or possible errors relating to treatment or care (n = 7). Overall, the review showed that clinicians handled the medical death certificate in a competent and careful manner. However, based on the content of the files, the review identified individual and avoidable misclassifications as to the manner of death and improbable causes of death; it also demonstrated that information on the epicrisis is often missing and needs significant improvement. PMID- 29465870 TI - ? PMID- 29465869 TI - Unusual planned complex suicide committed with a muzzle-loading pistol in combination with subsequent hanging. AB - In Germany, suicides by firearms are not very common in contrast to deaths by hanging and intoxications. The use of historical muzzle-loading firearms in the context of suicides is a rarity. Contact shots from muzzle loaders cause an unusual wound morphology with extensive soot soiling. We report the case of a 59 year-old man, who committed a planned complex suicide by shooting into his mouth with a replica percussion gun in combination with hanging. The gunshot injury showed strong explosive effects in the oral cavity with fractures of the facial bones and the skull associated with cerebral evisceration (so-called Kronlein shot). Due to the special constellation of the case with hanging immediately after the shot, external bleeding from the head injuries was only moderate. Therefore, the head injuries could be assessed and partially reconstructed already at the scene. PMID- 29465871 TI - [Treatment of hyperkalemia: 2.0 version]. AB - Hyperkaliaemia is a serious electrolyte disorder that is favored by many comorbidities, such as chronic renal failure or some treatments such as renin angiotensin-aldosterone system blockers. The new oral treatments by chelation of intestinal potassium have demonstrated : 1) their effectiveness in the management of serum potassium by maintaining the treatments at optimal dosages ; 2) their safety of use by the absence of serious side effect and 3) the ease of use with a daily intake. PMID- 29465872 TI - [Acid uric : key player in a recently recognized devastating nephropathy and in the development of chronic kidney disease.] AB - Uric acid has been known since long ago for its implication in gout and in certain kinds of nephrolithiasis. However, its role in models of acute and chronic nephropathies has been the focus of many new developments. The so called Mesoamerican nephropathy is a devastating disease that has caused more than 20'000 deaths in central America these last few years among sugarcane workers. Acid uric could play a key role in its physiopathology. Moreover, acid uric tends to be recognized as an independent factor of development and progression in chronic kidney disease, opening a way for new therapeutic targets. PMID- 29465873 TI - [What place for therapeutic education in nephrology ?] AB - Chronic kidney disease (CKD) usually goes unrecognized for patients until late symptomatic stages. In preterminal CKD, extrarenal substitution methods are usually presented to patients. This is felt like a breakdown, implying major modifications of everyday life. Acquisition of health literacy is necessary for patients with CKD to become autonomous and increase their empowerment toward the disease. Therapeutic education in nephrology plays a major role in improving the care of CKD patients. PMID- 29465874 TI - [Gut microbiota and kidney diseases : dangerous liaisons?] AB - Recent studies have found a relationship between the kidney and the intestinal microbiome, called the colo-renal axis. Mounting evidence suggests that patients suffering from chronic kidney disease (CKD) have an altered composition of gut microbiota. This leads to 1) the increased fermentation of intestinal proteins to uremic toxins such as p-cresyl sulphate and indoxyl sulphate, 2) an altered, more 'leaky' intestinal barrier, and 3) translocation of bacteria and toxins from the gut lumen to the circulation, inducing systemic inflammation. This may contribute to the increased morbidity and mortality in this population. Future studies are needed to confirm this hypothesis, and to assess whether manipulating the intestinal microbiota with pre-, pro-, or symbiotics may alter the development and course of CKD. PMID- 29465875 TI - [Calcific uremic arteriolopathy (calciphylaxis) : update in 2018]. AB - Calciphylaxis is a rare disease with a poor prognostic that mostly occurs in patients with renal failure. Diagnosis is difficult and skin biopsy is the gold standard diagnostic procedure, although it may aggravate skin lesions. Identification of the typical cutaneous signs is important to initiate adequate medical care. Several differential diagnoses must be excluded. Treatments should include appropriate pain management, local wound pain, daily dialysis, intravenous sodium thiosulfate treatment, hyperbaric oxygenotherapy, thigh control of calcium-phosphate metabolism and interruption of medications that could contribute to calciphylaxis. Palliative care should be considered in uncontrolled clinical course. PMID- 29465877 TI - ?

AB - Renal transplantation is the first-line therapy for eligible patients with end stage kidney disease. However, approximately 20 % of cadaveric graft recipients need to start dialysis at 5 years. The transition period between transplantation and dialysis is at high risk of complications, but data exploring this issue are scarce. In this retrospective study from dialysis centres of the Canton de Vaud, we analysed the clinical data and management of these patients at the beginning of dialysis after graft loss, and up to one year after dialysis start. Our data show that such patients suffer from a high rate of complications, such as urgent start of dialysis, hospitalizations, severe hypertension and depression. We suggest that clinical management in this period should be revisited. PMID- 29465878 TI - ? PMID- 29465879 TI - ? PMID- 29465880 TI - ? PMID- 29465881 TI - ? PMID- 29465882 TI - ?

AB - Meningiomas are one of the most frequent primary intracranial tumours, representing one-third of all intracranialneoplasms. The vast majority of meningiomas are histologically benign, but recurrence and progression is quite frequent. They occur usually between the 6th and 7th decade, the female/male ratio is 3:2. Although rare in pregnancy, when occurring, they can cause serious, life-threatening complications due to rapid growth and unfavourable localisation. There are two dominant hypothesis explaining rapid growth in pregnancy: the role of hormonal effects and hemodynamic changes. Several studies tested these theories but none provided unequivocal answer probably because the pathomechanism is complex and multifactorial. We provide an overview of the pathomechanism of meningiomas in pregnancy with emphasis on data obtained by advanced neuropathological, molecular biological, bioinformatic, imaging and epidemiological methods. A better understanding of the processes leading to meningioma development and growth in pregnancy will help us to design personalized therapy and reduce morbidity and mortality. PMID- 29465886 TI - Syndrome of trephined-underestimated and poorly understood complication after decompressive craniectomy. AB - Decompressive craniectomy (DC) is still a matter of debate, with a numerous complications as expansion of haemorrhagic contusions, external cerebral herniation, subdural hygromas, post-traumatic hydrocephalus (HC). The often overlooked "syndrome of the trephined" (ST) as a delayed complication of DC also known as sinking skin flap sy initially described in 1939.ST is characterised by the neurological changes associated with alteration of the pressure/volume relationship between intracranial pressure (ICP), volume of cerebrospinal fluid (CSF), blood, and brain tissue in patients with large bone defects. This review aims at elucidating the mechanisms responsible for the development of ST, and providing useful tips and red-flag signs for healthcare professionals involved with care of post DC patients. Symptoms identified on time could help to develop appropriate treatment strategies for this suddenly deteriorating, but possible reversible condition. Although the treatment strategy is straightforward, calling for a prompt cranioplasty, the correction of HC through CSF diversion devices might require a lengthy optimisation period. Continuous changes in the setting of the shunting systems or spinal tap might lead to dangerous swinging of the midline structures causing further neurological deterioration. Thus, finding the right balance in terms of clinical management often represents a significant challenge. PMID- 29465887 TI - [The role of zonisamide in the management of pediatric partial epilepsy]. AB - In our review we discuss the group of approved antiepileptic drugs for children in Hungary. We cite the results of the review conducted by the International League Against Epilepsy on antiepileptic drug efficacy and effectiveness as initial monotherapy for newly diagnosed epileptic seizures and syndromes in pediatric age group. 25% of pediatric epilepsy is therapy resistant, so we further need new drugs, which must be investigated according to the rules of the European Medicine Agency. The ethical dilemmas of childhood drug studies lead to the situation that the new antiepileptic drugs, approved as monotherapy in adult epilepsies, are in the majority just in add-on regimen tested in pediatric patients. As clinicians we appreciate open label extension safety studies. An old new antiepileptic drug in Europe is zonisamide. Though it was approved for first line monotherapy in pediatric and adult patients with partial and generalised epilepsy in 1989 in Japan, the European Medicine Agency licensed its use as adjunctive therapy in children aged 6 years or older with partial seizures (with or without secondary generalisation) just in 2013. The results of the openlabel extension study appeared in 2014. The mean dose received was 7.5 mg/kg/day. During the open label phase 11% of the patients achieved seizure freedom and it was maintained throughout the study. The drug was generally well tolerated. The most frequently reported treatment-related adverse events were decreased weight (6%), decreased appetite (4%), and headache (2%). No new or unexpected side effects emerged. In conclusion oral zonisamide as adjunctive therapy in pediatric patients aged 6-17 years with partial seizures demonstrated an acceptable safety and tolerability profile and efficacy over a period at least 1 year. So it is a good treatment option in this population. PMID- 29465888 TI - [Angioneuritic edema in ischaemic stroke patients treated with rt-PA]. AB - Data of our 254 patients who were treated with rt-PA between 1st of Jan, 2011 and 31st of Dec, 2014 were processed. We focused on angioneurotic oedema as allergic complication of thrombolysis which caused life threatening respiratory obstruction in two cases. We describe these two patients' history. Out of 254 patients six (2.3%) suffered angioneurotic edema caused respiratory obstruction in two (0.90%) cases. This occurrence is approximately 1.3-5.1% in literature. Five, out of six patients who suffered from angioneurotic oedema, had been treated with ACE inhibitors or ARB before. The role of ACE inhibitors is known in metabolism of bradykinin cascade. Plasmin which present during thrombolysis, precipitates biochemical mechanisms of this potential life threatening complication. Therefore rt-PA alone can be the cause of angioedema, but it can be more frequent together with ACE inhibitors therapy. PMID- 29465889 TI - [Transthyretin familial amyloid polyneuropathy - three Hungarian cases with rare mutations (His88Arg and Phe33Leu)]. AB - Introduction - Transthyretin familial amyloid polyneuropathy is a rare autosomal dominant progressive systemic disesase of adults caused by endoneural amyloid deposition due to point mutations of the transthyretin gene. It is the most severe form among hereditary polyneuropathies, being fatal within 10 years if left untreated. The disease is underdiagnosed, the late onset forms (above the age of 50) being probably more widespread than previously thought. Early diagnosis is essential as the early introduction of causal therapy (tafamidis) slows progression and prolongs survival. Patients - We report here three non related Hungarian cases of transthyretin familial amyloid polyneuropathy with non Val30Met mutations (His88Arg in two cases, Phe33Leu in one case). They were all characterized by late-onset, progressive, length-dependent, axonal, sensorimotor polyneuropathy and the simultaneous presentation of severe restrictive cardiomyopathy. In all three cases, clinical and electrophysiological signs of myopathy were also present, suggesting the involvement of skeletal muscles as well. In two cases, high resolution ultrasound of the peripheral nerves was also performed, which showed segmental structural alterations (change or loss of fascicular structure) and some increase of echogenicity of the interfascicular epineurium, without substantial enlargement of the nerves. Conclusion - In Hungary, mainly the rare, non-Val30Met mutation forms of transthyretin familial amyloid polyneuropathy are encountered, as in our cases. As opposed to the Val30Met forms, these mutations are characterized by late onset and simultaneous presentation of severe cardiomyopathy. Our report highlights the importance of considering transthyretin familial amyloid polyneuropathy in the differential diagnosis of late-onset, progressive, axonal polyneuropathies of unknown etiology, particularly if associated with cardiac disease.

Materials and methods - We studied combined and intravenous anesthesia detecting pre-and postoperative cognitive functions, intraoperative haemodynamic parameters, demographic data, other data of case history and surgical data. The Montreal Cognitive Assessment test was applied in the randomized, prospective study. The preoperative data served as basis for comparison. The second test was performed following surgery when patients were fully awake. Both groups included 30 patients. Results and conclusion - After both narcosis methods (postoperative second hour) cognitive functions were significantly deteriorated (p<0.05). Median MoCA before sevoflurane anesthesia was 24 points (interquartile range: 22-25), postoperative value was 20 (19-21) (p<0.05). Median MoCA before propofol anesthesia was 24 points (23-26), postoperative value was 20 (18-22) (p<0.01). Intraoperative arterial blood pressure, pulse rate and oxygen saturation values did not correlate with worsening of cognitive function (Pearson correlation coefficient values between -0.19 and 0.42). Execution is influenced by age (negative correlation) and education (positive correlation). PMID- 29465891 TI - Gray matter atrophy in presymptomatic Huntington's patients. AB - Background and purpose: Background - Huntington's disease is a progressive disease in which neurodegeneration is on-going from the early presymptomatic phase. Development of sensitive biomarkers in this presymptomatic stage that are able to monitor the disease progression and test the efficacy of putative neuroprotective treatments are essential. Methods: Methods - Seven presymptomatic Huntington mutation carriers and ten age-matched healthy controls were recruited. Six of the patients participated in a 24 months longitudinal study having MRI scans 12 and 24 months after the baseline measurements. High resolution T1 weighted images were carried out and voxel based morphometry was used to analyse the data. Apart of group differences, correlation of CAG repeat number with focal cortical thickness and with global gray matter volume was calculated. Results: Results - Focal cortical atrophy was found bilaterally in the superior temporal sulcus and in the left middle frontal gyrus in presymptomatic Huntington patients in whom no sign of cognitive or motor deterioration was detected. Global gray matter atrophy (p<0.048) and decreased total brain volume was found. The number of CAG triplets showed no correlation with the focal gray matter atrophy and total brain volume. Strong correlation between the CAG repeat number and global gray matter volume was found (p<0.016). Conclusion: Conclusion - Cortical atrophy is apparent in the early, presymptomatic stage of the disease. With further validation in large patient sample atrophy measure could be biomarker of disease progression and putatively of neurodegeneration. PMID- 29465892 TI - Burning mouth syndrome: Evaluation of clinical and laboratory findings. AB - Background and purpose: Burning mouth syndrome is a chronic and persistent painful condition characterized by burning sensation in the oral mucosa. We investigated the etiological factors of patients presented with the history of burning in the mouth who admitted our outpatient clinics over the 8-years period and who had no underlying identifiable local factors. We also tried to determine their demographic and clinical characteristics. Our aim was to investigate the association between burning mouth and psychiatric disorders such as depression and anxiety, chronic diseases like diabetes mellitus (DM) and other laboratory studies in patients complaining of solely burning in the mouth. Methods: The study included patients with the history of burning in mouth who presented in our outpatient clinic between 2005 and 2012. They were evaluated by a neurologist, a psychiatrist, an internist, and a dentist. Complete blood counts, biochemical analysis and cranial magnetic resonance imaging (MRI) were performed for all patients. Results: A total of 26 (22 (84%) females, 4 (15%) males; mean age 55.9 years) patients were enrolled in this study. Five (19.2%) of the patients had depression, 2 (7.7%) had anxiety disorder, 2 (7.7%) had diabetes mellitus, 8 (30%) had B12 vitamin deficiency, 3 (11.5%) had decreased ferritin levels in blood, and 1 (3.8%) had folic acid deficiency. Cranial MRI of all patients were normal. Nine patients (34.6%) had no etiological causes. Conclusion: A multidisciplinary approach in the management of burning mouth and establishment of common criteria for the diagnosis would provide insight into the underlying pathophysiological mechanism. PMID- 29465893 TI - Association of anterior thoracic meningocele and azygos lobe of the lung. AB - Here we report an anterior thoracic meningocele case. Twoyears- old female patient was presented with kyphosis. Azygos lobe of the lung was also demonstrated during radiological studies. Posterolateral thoracotomy incision and extralpeural approach was performed for excision of the anterior meningocele to untether the cord. Although both anomalies are related to faulty embryogenesis and it is well known that faulty embryogenesis may also reveal coexisting abnormalities, we could not speculate a common mechanism for anterior thoracic meningocele and azygos lobe of the lung association. PMID- 29465894 TI - Four cases of GABAB receptor encephalitis. AB - GABAB receptor (gamma-aminobutyric acid type B receptors - GABABR) encephalitis is a rare manifestation of autoimmune encephalitides. We report four cases - including the first two Hungarian patients - with some peculiar features. One patient developed subacute disorientation and almost complete loss of short-term memory, but no epilepsy. Without immunotherapy, his memory spontaneously improved up to mild cognitive impairment in six weeks. GABABR antibodies persisted in his serum, and 18 months later, FDG-PET detected abnormal mediastinal lymph nodes and small cell lung cancer (SCLC). Another patient had persistently decreased sodium content in the peripheral blood. In those three patients who died, CSF was abnormal, but CSF was not pathological in the patient, who spontaneously improved. Brain MRI indicated signal intensity changes in the medial temporal areas in three cases. SCLC was found in three patients. Only the patient, who spontaneously improved, survived for more than 24 months. In summary, our cases show that (i) GABABR encephalitis may develop without epilepsy; (ii) the severe short-term memory loss can spontaneously improve; (iii) persistent hyponatremia can be present in the blood; (iv) the patient with benign course without epilepsy and CSF abnormality survived; (v) spontaneously remitting encephalitis can precede SCLC by 1.5 year, which emphasizes that repeated search for cancer is of paramount importance even in cases with spontaneous improvement. PMID- 29465895 TI - [Clinical neurophysiological methods in diagnosis and treatment of cerebrovascular diseases]. AB - Neurophysiological methods are gaining ground in the diagnosis and therapy of cerebrovascular disease. While the role of the EEG (electroencephalography) in the diagnosis of post-stroke epilepsy is constant, quantitative EEG para-meters, as new indicators of early efficiency after thrombolysis or in prognosis of patient's condition have proved their effectiveness in several clinical studies. In intensive care units, continuous EEG monitoring of critically ill patients became part of neurointenzive care protocols. SSEP (somatosesnsory evoked potencial) and EEG performed during carotid endarterectomy, are early indicative intraoperativ neuromonitoring methods of poor outcome. Neurorehabilitation is a newly discovered area of neurophysiology. Clinical studies have demonstrated the effectiveness of repetitive transcranial magnetic stimulation (rTMS) in the rehabilitation of stroke patients. Brain computer interface mark the onset of modern rehabi-litation, where the function deficit is replaced by robotic tehnology. PMID- 29465896 TI - Insights into the structure and function of the hippocampal formation: Relevance to Parkinson's disease. AB - The link between the hippocampus and declarative memory dysfunctions following the removal of the medial temporal lobe opened unexplored fields in neuroscience. In the first part of our review, we summarized current theoretical frameworks discussing the role of hippocampus in learning and memory. Several theories are highlighted suggesting that the hippocampus is responsible for assembling stimulus elements into a unitary representation that later can be utilized to simulate future events. The hippocampal formation has been implicated in a growing number of disorders, from neurodegenerative diseases to atypical cognitive ageing and depression. Recent neuroimaging studies provided new opportunities to study in detail the hippocampal formation's role in higher levels of the nervous system. We will present data regarding the regional specialization of the hippocampus in experimental models developed for healthy and neurological conditions with a special focus on Parkinson's disease. Combined evidence from neuroimaging studies suggested that hippocampal volume is reduced in non-demented, newly diagnosed patients with Parkinson's disease, which is associated with impaired memory performance. These findings proposed that, beyond the well-known striatal dopamine loss, impaired hippocampal synaptic plasticity may contribute to cognitive and affective impairments in early Parkinson's disease. PMID- 29465897 TI - [Effects of nasal provocation with a single-dose allergen on the explicit and implicit memory of physically active and inactive patients with ragweed allergy]. AB - Background and purpose: Allergy is an endemic disease and has a considerable impact on the quality of life. This study aimed to measure the effect of active allergic rhinitis on memory functions of physically active and inactive patients with ragweed allergy. Methods: Memory functions were assessed before and after allergen exposure. Participants in both groups were provoked nasally with 30 IR/mL ragweed allergen in each nostril. Explicit memory was measured with story recalling and implicit memory was investigated with reaction time task. Results: In neuropsychological assessments athletes performed significantly better, compared with the control group after allergen provocation in short-term and long term memory functions. There was no difference between the groups in the implicit tasks. Athletes have achieved better results after provocation, comparing to the baseline test and the tests that measured short-term and long-term memory functions. Conclusion: Short-term disturbing factors, e.g. swollen nasal mucosa, sneezing, and watery eyes after provocation did have not caused deterioration in cognitive functions. A single-shot allergen in high doses have caused an increase of mental concentration, which was more pronounced in athletes. PMID- 29465898 TI - Functional neurotoxicity and tissue metal levels in rats exposed subacutely to titanium dioxide nanoparticles via the airways. AB - Background and purpose: Nanoparticles of titanium dioxide are suspected neurotoxic agents and have numerous applications possibly resulting in human exposure by several ways including inhalation. In the present work, rats were exposed to spherical TiO2 nanoparticles of two different sizes by the intratracheal route. It was investigated how the neuro-functional alterations, detected by electrophysiological and behavioral methods, were related to the concentration of Ti in the tissue samples and what the influence of the size of the NPs was. Methods: Rats (young adult Wistar males, 10/group) were exposed to TiO2 nanoparticles of ca. 10 and 100 nm diameter (suspension medium: neutral PBS with 1% hydroxyethyl cellulose) by intratracheal instillation in 5 and 18 mg/kg b.w. dose; 5 days per week for 6 weeks. Controls were instilled with saline, and vehicle controls, with the suspension medium. To see general toxicity, body weight was checked daily, and organ weights were measured at the end of experiment. Grip strength test, to assess motor function damage, was done before and after the 6-week treatment. Finally, the rats were anesthetized with urethane, spontaneous cortical activity and sensory evoked potentials were recorded, then the rats were dissected and tissue samples were taken for Ti level measurement. Results: Body weight gain indicated no general toxicity, and no significant change in the relative organ weights, except that of the lungs, was seen. However, change of time-to-fall in the grip strength test, and latency of cortical evoked po-tentials, were altered in the treated groups, indicating functional damage. Correlation of these alterations with the cortical Ti level was dissimilar for the two sizes of nanoparticles. Conclusion: The results provided further support to the functional neurotoxicity of TiO2 nanoparticles. The exact role of particle size, and the mechanisms involved, remain to be elucidated. PMID- 29465899 TI - Electroclinical and prognostic characteristics of epilepsy patients with photosensitivity. AB - Background and purpose: Epilepsy with photosensitivity (PSE) is one of the reflex epilepsy types with pathophysiology still unexplained. In our study we aimed to evaluate the clinical, electroencephalogram (EEG) and prognosis of patients with PSE diagnosis. Methods: A total of 44 patients with PSE diagnosis according to international classification were included in this retrospective and cross sectional study. The age, gender, syndrome, clinical and EEG characteristics of patients, and treatment response were investigated. Results: The mean age was 22.09+/-6.49 years for 28 females and 16 males included in the study. Of patients, 17 had idiopathic photosensitive occipital lobe epilepsy (IPOLE), 11 had juvenile myoclonic epilepsy (JME), 11 had other PSE and 5 had juvenile absence epilepsy (JAE), with the most common visual trigger factors television and sunlight. In terms of seizure type, the most common was generalized tonic clonic seizure (GTCS), with myoclonus, absence and other seizure types observed. There was family history present in 17 patients and valproic acid was most commonly used for treatment. Conclusion: As noted in the literature, our data show that PSE has defined age group and clinical presentation, good prognosis but requires correct choice of medication for treatment. It is thought that good description of these epilepsy types will reduce misdiagnosis and mistreatment rates. PMID- 29465900 TI - Alteration of mean platelet volume in the pathogenesis of acute ischemic stroke: cause or consequence? AB - Background and purpose: Platelets have a crucial role on vascular disease which are involved in pathogenesis of ischemic stroke. Platelet size is measured as mean platelet volume (MPV) and is a marker of platelet activity. Platelets contain more dense granules as the size increases and produce more serotonin and tromboglobulin (b-TG) than small platelets. In this study, the alteration of MPV values were investigated in patients with acute stroke, who had MPV values before stroke, during acute ischemic stroke and 7 days after the stroke. The relationship between this alteration and risk factors, etiology and localization of ischemic stroke were also investigated. Methods: Sixty-seven patients with clinically and radiologically established diagnoses of ischemic stroke were enrolled into the study and stroke etiology was classified by modified Trial of Org 10 172 in Acute Stroke Treatment (TOAST) classification and, modified Bamford classification was used for localization and stroke risk factors were also evaluated. The platelet counts and MPV values from patient files in patients who had values before stroke (at examination for another diseases), within 24 hours of symptom onset and after 7 further days were analysed. Results: MPV values increased after stroke (10.59+/-2.26) compared with acute stroke values (9.84+/ 1.64) and the values before stroke (9.59+/-1.72) (p<0.0001); this alteration of MPV values occured 7 days after stroke (p<0.016). There was a positive correlation between age and MPV values during acute stroke (r=0.270; p<0.05). Patients with atrial fibrillation had higher alteration in the time of MPV compared with patients without atrial fibrillation (p>0.006). We assessed for gender, men (n=38) had a higher alteration in the time of MPV compared with women (n=29) (p=0.013). Conclusion: Although there was no alteration of platelet counts, MPV values were increased 7 days after stroke in patients with acute ischemic stroke. PMID- 29465901 TI - Association of cardiovascular risk factors and Parkinson's disease - case-control study in South East Hungary. AB - Background and purpose: Parkinson's disease (PD) has the second highest incidence among neurodegenerative diseases in the world population. The study aimed to investigate the presence of some cardiovascular risk factors - dyslipidemia, diabetes, and hypertension - in PD patients and to compare their risk with non-PD population in South East Hungary. Methods: A case-control study was conducted at the Department of Neurology, University of Szeged, Hungary. The study included 1299 subjects out of which 620 patients were identified as cases of diagnosed PD and 679 as controls. Logistic regression analyses were conducted to reveal the association of vascular risk factors with PD. Results: In the univariate analysis, diabetes mellitus was positively associated with PD, while dyslipidemia showed negative association to it in the total population, and no significant associations were found between hypertension and PD. The multivariate logistic regression models showed that the odds of diabetes mellitus was higher (OR=2.86), while the odds of dyslipidemia was lower (OR=0.58) among PD patients than in the control group. Hypertension showed a different pattern by gender: the odds of registered hypertension was significantly lower in female PD patients (OR=0.68), whereas the result was not significant in males. Conclusion: This is the first study that provides a comprehensive view of the cardiovascular risk factors in PD patients in Hungary and shows considerable relationship between diabetes mellitus and PD. PMID- 29465902 TI - [The facets of creativity in the light of bipolar mood alterations]. AB - The link between creativity, as the highest expression form of human achievement, and bipolar disorder came into focus of scientific investigations and research. Accomplished writers, composers and visual artists show a substantially higher rate of affective disorders, prodominantly bipolar mood disorders, comparing to the general population. Then again, patients afflicted with bipolar II subtype (hypomania and depression), as well as persons presenting the mildest form of bipolar mood swings (cyclothymia) possess higher creative skills. It evokes therefore that certain forms and mood states of bipolar disorder, notably hypomania might convey cognitive, emotional/affective, and motivational benefits to creativity. The aim of this paper is to display expression forms of creativity (writing, visual art, scientific work) as well as productivity (literary and scientific work output, number of artworks and exhibitions, awards) in the light of clinically diagnosed mood states at an eminent creative individual, treated for bipolar II disorder. Analysing the affective states, we found a striking relation between hypomanic episodes and visual artistic creativity and achievement, as well as scientific performance, whereas mild-moderate depressed mood promoted literary work. Severe depression and mixed states were not associated with creative activities, and intriguingly, long-term stabilised euthymic mood, exempted from marked affective lability, is disadvantageous regarding creativity. It seems, thereby, that mood functions as a sluice of creativity. Nevertheless, it is likely that there is a complex interaction between bipolar mood disorder spectrum and psychological factors promoting creativity, influenced also by individual variability due to medication, comorbid conditions, and course of disorder. PMID- 29465903 TI - Population structure and reproduction of a migratory fish Leporinus piau (Characiformes: Anostomidae) in a semiarid tropical reservoir, Brazil. AB - Migratory fishes have been seriously impacted by the building of reservoirs and because of the negative effects of these projects such as the interruption of migratory routes, reduction or elimination of spawning/feeding areas, and initial development can influence the population structure the migratory fishes, resulting in reduction in abundance. Leporinus piau is migratory fish widely distributed in the watersheds of the Brazilian semiarid and it is of importance for artisanal and sport fishing. The goal of the study was to evaluate the population structure and reproductive dynamics of the migratory species Leporinus piau in the Pau dos Ferros Reservoir, which is located in the semiarid region of Brazil. The CPUE, length structure, length-weight relationship, length at first maturity, sex ratio, gonad development and IGS were analyzed. Collections were performed quarterly between February 2011 and November 2012 using gillnets. The captured fish were counted; the standard length (cm) and total weight (g) were measured, and dissected to determine the sex and gonad maturity stage. The rainfall and reservoir water levels were recorded, and their correlations with the reproductive period and CPUE were analyzed. A total 549 individuals were captured. The average CPUE varied between 0.0259 individuals/m2*h (May/2011) and 0.0008 individuals/m2*h (August/2012), and significant differences were observed; however, significant correlations were not observed between rainfall and reservoir levels. The standard length varied between 5.9 cm and 20.7 cm, and the weight varied between 4.16 g and 271.5 g. A histogram analysis revealed that the 5-10 cm standard length class was the most abundant for juveniles and that the 10 15 cm class was the most abundant for adult females and males. The weight-length relationship was best fit by the equation log10Wt = -1.57711 + 3.00707 Log10 Ls, and the species presented isometric growth. The estimated length at first maturity was 12.76 cm. A total of 148 males and 82 females were collected (1.81:1, M:F), and these values were significantly different. The highest GSI was observed in February 2011 for both females (10.69) and males (5.72), and the GSI was significantly and positively correlated with rainfall. We concluded that the L. piau population is established in the reservoir and found that its reproduction period occurred during the rainy season between February and May. PMID- 29465904 TI - Effect of a major highway on the spatial and temporal variation in the structure and diversity of the avifauna of a tropical premontane rain forest. AB - Roads immersed in conservation areas will increase in number, size, and traffic over the next decade, and thus, understanding their effects on forest-dependent wildlife is crucial for improving current management practices and reducing the negative impacts of roads on sensitive species. We examined the influence of route 32 (a.k.a. Guapiles Highway) on temporal and spatial changes in the structure of the avifauna of Braulio Carrillo National Park, Costa Rica, a site crossed by this road along 25 km. The highway connects the capital city of San Jose with the Harbor of Limon in the Caribbean Sea (142 km). Although the road is narrow (12 m in width and comprised by two lanes along most of the route) it services over 1.5 million motor vehicles per year, 12 % are heavy trucks and trailers. We expected the highway to divide the avifauna, and thus to observe significant differences in species structure on opposite sides of the road. We described changes in bird diversity between wet and dry seasons at Las Palmas and Ceibo trails located on opposite sides of the highway (14 point counts per trail), and evaluated how abundance and diversity varied with road distance. Censuses took place during wet and dry seasons from 2002 to 2005. We listed 245 species and 6 035 observations during the 4-yr survey. Rare species dominated the avifauna (65 % of species < 5 observations), and species overlap between trails was high (Sorensen= 71 %; Morisita= 0.96). Species accumulation curves varied little among trails, yielding 190 species. Resident species represented 70 % of observations, followed by elevational (15 %) and long-distance migrants (1-2 %). Understory species were the most abundant (60 %) followed by canopy birds (30 %). Species turnover rate was 55 % between seasons, but species composition between trails remained homogeneous. Overall, birds were avoiding the road (abundance increased away from the road) although other diversity parameters (richness, dominance, Shannon index, and equitability) were not influenced by road proximity. Although the avifauna remained homogeneous on both sides of the road, which did not support the fragmentation hypothesis, the highway reduced the abundance and diversity of specialized understory insectivores associated with primary forests near the road. This highway will expand outside the National Park (from 2 to 4 lanes along 107 km from Rio Frio to Limon) in the next years, which will increase traffic volume and road impacts within the Park. Roads are increasing across highly diverse tropical areas justifying the need for management practices based on the identification of sensitive groups. PMID- 29465905 TI - The geographic distribution of Costa Rican velvet worms (Onychophora: Peripatidae). AB - Velvet worms, "peripatus" or onychophorans, are "living fossils" that were geographically widespread in Cambrian seas but now occur exclusively on terrestrial habitats. The only extant species studied in some detail are those from Costa Rica, but their real geographic distribution was in urgent need of revision. To solve this problem we visited the localities mentioned in all the original taxonomic descriptions and redescriptions. These visits covered a 25 year period (1988-2014) and included interviews with local residents. We also examined all Costa Rican collections, and checked the information in old maps and books. Here we critically review geographic data, correct errors, designed neotype localities, report on the survival of populations after heavy volcanic eruptions or urbanization, and present the correct geographical distribution for the seven currently described Costa Rican species. PMID- 29465906 TI - [Population ecology of Heteromys pictus (Rodentia: Heteromyidae), in a tropical deciduous forest with human disturbance, in Oaxaca coast, Mexico]. AB - Spiny pocket mice Liomys and Heteromys are forest-dwelling granivorous rodents distributed in seasonally dry forest or thorn scrub along the Pacific lowlands or xeric regions in the Mexican Plateau. We analyzed the population dynamics of the spiny pocket mouse Heteromys pictus, in the coast of Oaxaca, Mexico, in two sites of tropical deciduous forest with different degrees of disturbance: ZPP = less disturbed site, and ZMP = more disturbed site. Two plots were established in each area with 66 trap stations; we used the capture-recapture method and trapping for 12 periods for one year. Population density was estimated using the method of Minimum Number of Individuals Known Alive (MNKA). We captured 706 individuals, 290 for the ZPP and 416 for the ZMP. The population density ranged from 28 to 142 ind./ha for both zones, but it was higher for the ZMP (54 against 142 ind./ha). The population density for both areas increased during the rainy season and coincided with the increased recruitment of adults. Reproductive activity occurred throughout the study period in both areas, but it was higher for the ZMP. The sex ratio in the ZPP was 1:1 while in the ZMP was 1:0.75. In the ZMP we found a higher population density and reproductive activity in females, compared to the ZPP. These results suggest that H. pictus prefers the ZMP, indicating that thespeciesisnot significantly affected by human disturbance in the studied location. PMID- 29465907 TI - In vitro antioxidant activity and qualitative phytochemical analysis of two Vismia (Hypericaceae) species collected in Los Andes, Venezuela. AB - Vismia genus is distributed mainly in tropical and subtropical regions of Central, South America and some areas of Africa. According to previous investigations, antioxidant potential of Vismia species might be related to anthrones, anthraquinones, flavonoids and phenol derivatives biosynthesized by these plants. In this investigation, phytochemical screening of Vismia baccifera (VB) from Merida-Venezuela and Vismia macrophylla (VM) from Tachira-Venezuela methanolic extracts, carried out using various chemical assays, revealed an abundant presence of anthraquinones in both species analyzed. Glycosides were also present while flavones and dehydroflavones were observed abundantly in VB but moderated in VM. Triterpenes were also detected and steroids showed to be abundant in VM but moderate in VB. On the other hand, antioxidant capacity measured by the DPPH assay showed that VM possesses a stronger antioxidant activity than VB with IC50 5.50 ug mL-1. Phenol and flavonoid assays carried out by Folin-Ciocalteu and colorimetric test also revealed that methanol extracts of both species contain high concentrations of these metabolites. A relationship between the antioxidant activity, total phenol and flavonoids content of the extracts analyzed was demonstrated in this investigation since those samples with higher phenolic concentrations showed likewise higher antioxidant activity. PMID- 29465908 TI - Does Plan B work? Home range estimations from stored on board and transmitted data sets produced by GPS-telemetry in the Colombian Amazon. AB - Telemetry based on Global Positioning Systems (GPS) makes possible to gather large quantities of information in a very fine scale and work with species that were impossible to study in the past. When working with GPS telemetry, the option of storing data on board could be more desirable than the sole satellite transmitted data, due to the increase in the amount of locations available for analysis. Nonetheless, the uncertainty in the retrieving of the collar unit makes satellite-transmitted technologies something to take into account. Therefore, differences between store-on-board (SoB) and satellite-transmitted (IT) data sets need to be considered. Differences between SoB and IT data collected from two lowland tapirs (Tapirus terrestris), were explored by means of the calculation of home range areas by three different methods: the Minimum Convex Polygon (MCP), the Fixed Kernel Density Estimator (KDE) and the Brownian Bridges (BB). Results showed that SoB and IT data sets for the same individual were similar, with fix ranging from 63 % to 85 % respectively, and 16 m to 17 m horizontal errors. Depending on the total number of locations available for each individual, the home ranges estimated showed differences between 2.7 % and 79.3 %, for the 50 % probability contour and between 9.9 % and 61.8 % for the 95 % probability contour. These differences imply variations in the spatial coincidence of the estimated home ranges. We concluded that the use of IT data is not a good option for the estimation of home range areas if the collar settings have not been designed specifically for this use. Nonetheless, geographical representations of the IT based estimators could be of great help to identify areas of use, besides its assistance to locate the collar for its retrieval at the end of the field season and as a proximate backup when collars disappear. PMID- 29465909 TI - [The jaguar Panthera onca (Carnivora: Felidae) in "El Cielo" Biosphere Reserve, Tamaulipas, Mexico]. AB - Information on the ecology of jaguars (Panthera onca) in "El Cielo" Biosphere Reserve in Tamaulipas, Mexico is scant and limited to anecdotic records in a handful of publications. The objectives of our study were to: a) determine population density and structure of jaguars, b) compare their activity patterns with that of pumas (Puma concolor), c) ascertain potential prey relative abundance, and d) evaluate local resident's perception on loss of domestic animals due to jaguar predation. Between April 2013 and April 2014 we conducted camera trapping in Gomez Farias Township with a total sampling effort of 8 580 camera trap days. Besides, we completed 136 semi-structured interviews among local residents of Gomez Farias and Llera Townships to gather information on domestic animal losses attributed to jaguars and other carnivores. We identified eight different jaguar individuals during a complete year of camera-trapping, composed of four adult females, one juvenile female, two adult males and one juvenile male. We estimated a jaguar density of 5.9 +/- 1.3 jaguars/100 km2. Activity patterns for jaguars and pumas were similar as both were nocturnal and crepuscular in nature. The most abundant potential prey species for jaguars in the study site were Crax rubra, Cuniculus paca, Mazama temama, Odocoileus virginianus and Didelphis virginiana; while the rarest were Mephitis macroura and Procyon lotor. Interview results suggested that chickens, dogs, and house cats were the most consumed domestic animals from all reported losses by local residents (n= 107). This study represents the first attempt to describe jaguar ecology in "El Cielo" Biosphere Reserve; however, there is a need of additional monitoring efforts to determine the current status of jaguars in a larger area in order to establish conservation strategies. Finally, this jaguar population may have an important role in maintaining the species in the Sierra Madre Oriental biological corridor connecting populations in Nuevo Leon and San Luis states in Northeastern Mexico. PMID- 29465910 TI - [Diversity and biogeographic affinities of sharks, rays and chimaeras (Chondrichthyes: Elasmobranchii, Holocephali) of Mexico]. AB - The diversity of chondrychthyans in Mexico is described. The fauna is composed by 214 species (111 sharks, 95 rays and 8 chimaeras) and represents 17.3 % of the total number of species recorded worldwide. The families with the highest diversity comprise: Rajidae (14.5 %), Carcharhinidae (12.1 %), Pentanchidae, Triakidae, and Urotrygonidae (5.1 %). In terms of geographical distribution, the diversity on the Mexican Pacific slope reaches up to 56.1 % of those species inhabiting Mexican marine and brackish waters (120 species, 62 genera, 37 families and 14 orders); the diversity in the Atlantic slope resulted similar to that on the Mexican Pacific with 55.1 % of the species (118 species, 59 genera, 35 families and 13 orders). The biogeographical affinities of the Mexican chondrychthyan fauna are complex with 19.7 % of the species being circumglobal, 9.9 % transatlantic, 1.9 % transpacific, and 9.4 % endemic to the exclusive economic zone. Additionally, 36.6 % of the species recorded so far are endemic to the Eastern Pacific coast where the species are similar to those found in the Cortez biogeographic province (27.7 %), followed by the Californian (20.7 %), Panamanian (19.3 %), Galapagos (5.6 %) and Peruvian-Chilean (8.9 %). Likewise, 33.3 % are endemic of the Atlantic coast, where species are similar to those found in the Caribbean province (31.9 %), followed by the Carolinean (24.4 %) and the Brazilian (6.6 %).

AB - Several illnesses of vectorial origin have a great medical and veterinary relevance, due to the adaptations developed by the species involved in their transmission. To support preventive programs with updated ecological information of Ae. aegypti populations, an entomological survey was carried out in three Health Areas of Camaguey, Cuba, during low and high rain seasons of 2013. For this, we assessed the type and number of positive containers, quantified larvae and pupae in positive containers, according to the container location in or outside the house. Both the container representativeness percentage and the pupal index by specific containers were calculated (PIsC). The total of houses as well as the positive habitual-use and non-disposable containers were compared among weather seasons, using the non parametric Chi2 test. The existent relationship between the total of positive houses and the habitual-use and non-disposable container was explored through the test of proportions hypothesis, with a level of significance of P <= 0.05. Ae. aegypti colonized 73 different types of containers, being habitual-use and non-disposable a 23.2 %. This number included 76 % of the positive containers. The greatest larvae collections were obtained in exterior water tanks and barrels, with important pupal production (PIsC = 3.04 and 1.75, respectively), and as well as significant differences towards the rainy season respect to positive houses (PUIA: Chi2 = 32.89; P = 0.00; PUE: Chi2 = 127.44; P = 0.00 and PUJAM: Chi2 = 127.44; P = 0.00), and the habitual-use and non-disposable container (PUIA: Chi2 = 30.37; P = 0.00; PUE: Chi2 = 37.26; P = 0.00 and PUJAM: Chi2 = 81.82; P = 0.00). These data reinforce the priority given to the control and surveillance actions conducted by the community in their respective houses.

AB - The availability of information on species abundance in the Neotropic is insufficient, and this prevents the execution of precise analysis and the definition of adequate conservation strategies for endemic and threatened species. This study aimed to analyze the population size of the endemic and threatened subspecies Grus canadensis nesiotes. For this, a simultaneous census was undertaken in 24 count stations in Isla de la Juventud (IJ) and 32 stations in Ciego de Avila (CA), Cuba, during two consecutive days between 2008 and 2010. Abundance and behavior pattern (instantaneous method) were analyzed by habitat type, to help understand how cranes modify their behavioral pattern when the natural habitat is changed. Flocks in IJ had three individuals, and between 1.9 +/- 1.5 and 2.8 +/- 1.5 in CA. Population size in IJ was 164 individuals, and in CA of 137, 141 and 168 individuals for the 2008-2010 period, respectively. The counting efficacy was high (IJ: 91 %; CA: 81-87 %) and the numerical concordance was intermediate (IJ: 45.4 %; CA: 72 %). When comparing the habitat type, the abundance was higher in natural savannahs (83), followed by coastal flats (59), pines (23) and cattle pastures (7) in IJ; while in CA, marsh grasslands hosted the greatest abundance for the three years period (130; 120; 112), followed by grassland with palms (2; 17; 51) and cattle pastures (5; 4; 5). The cranes were fed more in cattle pastures and were more alert in natural savannas and marsh grasslands. The frequency of feeding and alert behaviors was different from the natural savannah/coastal flats and natural savannah/cattle pastures combinations in IJ. For CA, differences were found between marsh grasslands and marsh grasslands with palms. The population size increased by management strategies adopted in CA; nevertheless, might be affected by habitat loss associated with invasive alien plants in IJ. We propose the maintenance of prescribed fire in marsh grasslands under protection regime, as a strategy for long-term management to contribute with population growth.

AB - The productivity of arid legumes, such as Clusterbean (Cyamopsis tetragonoloba), Cowpea (Vigna unguiculata), Moth bean (Vigna aconitifolia) and Horse gram (Macrotyloma uniflorum), may remain stagnant over decades because of their high susceptibility to root diseases. Besides, there is a limitation on the information about molecular diagnosis and intraspecific genetic variability of root pathogens in arid legumes. To contribute in this field, we assessed a total of 52 isolates from 88 root samples that were found infected with fungal pathogens in Jodhpur, Jaipur and Bikaner Districts of Rajasthan. Diseased roots samples were analyzed following standard microbiological methods for fungus extraction and purification, and for genetic studies. Irrespective of the geographical location from where the diseased samples were collected, all pathogen isolates were clustered in RAPD dendrograms as per their respective genera. Phylogram, based on multiple sequence alignment, revealed that different genera (i.e. Fusarium, Neocosmospora and Syncephalastrum), separated from each other, and species within the same genera, clustered together with their reference sequences with apreciable bootstrap values. Out of 20 representative isolates representing each cluster and all outgroups sequenced, eight were molecularly identified as Neocosmospora vasinfecta, five as Fusarium solani, two as Neocosmospora striata, two as Fusarium acutatum, one as Syncephalastrum monosporum, one as Fusarium oxysporum and one as Fusarium species. The root pathogens of the arid legumes were found neither restricted to a geographical location nor were host specific in nature. Fusarium solani wilt in cowpea and seedling rot in moth bean, F. oxysporum wilt in moth bean, F. acutatum damping off in cowpea and Clusterbean, Fusarium sp. seedling rot in Clusterbean, Neocosmospora striata root rot in cowpea and wilt in Clusterbean and Syncephalastrum monosporum root rot in Clusterbean were molecularly identified as new fungal records as pathogens causing root diseases in arid legumes. PMID- 29465914 TI - Profile of plasmatic progesterone on pregnancy, and the postpartum estrus of Dasyprocta prymnolopha (Rodentia: Dasyproctidae). AB - The agouti (Dasyprocta sp.) is a hystricomorph rodent found in some regions of the Americas. It is an important cynegetic species, which indicates that the overhunting is a threat to their conservation. Very little is known about this wildlife in relation to what already has been studied in domestic animals. Thus, the knowledge on reproduction of wildlife becomes necessary and essential for the management and conservation of these natural resources. Specifically, studies regarding hormonal monitoring are important as a basic tool for research in modern reproductive biotechnology, and currently, there is no information on the progesterone changes during pregnancy of Dasyprocta sp., compared to other hystricomorphs. The aim of this study was to describe the profile of plasmatic progesterone during pregnancy, and report the restart of ovarian cycle in agouti after parturition. For this purpose, 18 black-rumped agoutis (Dasyprocta prymnolopha) born in captivity were used, and one or more consecutive pregnancies were observed. Copulation was confirmed by the presence of spermatozoa observed in the colpocytological examination. Blood samples were collected two times per week, and concentrations of progesterone, assessed in ten agoutis, were determined by radioimmunoassay. The onset of ovarian activity in six females was observed daily by colpocytological examination, starting on the seventh day postpartum. The gestational period observed in this study was 104.04 days (SD = 1.31) (101-106 days) (Number of cases, N = 26), and the interval between births was 126.03 days (SD = 18.40) (109-184 days). The plasmatic profile of progesterone during pregnancy showed a progressive increase from the 1st to the 5th week. The higher progesterone levels over this period (6.88 ng / mL, SD = 3.01) were detected in the 5th week. This value was similar (One-Way ANOVA, p > 0.05) to that observed in the 4th and 6th weeks, but was statistically different (One-Way ANOVA, p < 0.05) when compared to the other weeks. After the 6th week there was a progressive decrease in plasmatic progesterone levels. The animals showed a postpartum estrus of 12.04 days (SD= 4.29) (7-24 days) (N= 23). It was observed that 80.95 % (N= 19) of copulations during this period were fertile. This work contributed to understanding the dynamic changes in the progesterone levels during the pregnancy in agouti. Nevertheless, more studies are needed for a better appreciation of other endocrine and biological changes, in the mother and feto-placental unit of the agouti.

AB - The marine angiosperm Thalassia testudinum, commonly known as turtle grass, is a dominant seagrass that grows in the Caribbean Sea shelf associated to Syringodium filiforme. The hydroalcoholic extract of T. testudinum is rich in polyphenols; the most abundant metabolite in this extract is thalassiolin B, a glycosilated flavonoid with skin damage repairing properties, and antioxidant capacity among others. The present study aimed at generating information about the seasonal behavior of secondary metabolites, as well as to study the antioxidant capacity of the T. testudinum leaves extract, collected monthly during 2012 from the Northeast coastline of Havana, Cuba. For this study, spectrophotometric methods were used to determine the concentrations of polyphenols, flavonoids, anthocyanins, soluble carbohydrates and proteins, chlorophylls a and b, and antioxidant activity of the extracts. In general, results demonstrated seasonal variations of the analyzed parameters. Extracts prepared from the vegetal material collected in October and November showed the highest values of polyphenols (58.81 +/- 1.53 and 52.39 +/- 0.63 mg/g bs, respectivally) and flavonoids (44.12 +/- 1.30 and 51.30 +/- 0.67 mg/gdw, respectively). On the contrary, the lowest values of polyphenols were found in extracts of leaves collected in July and August (15.51 +/- 0.84 and 13.86 +/- 0.48 mg/g,respectively). In accordance with these results, the lower value of Inhibitory Concentration (IC50) was obtained to get a 50 % of maximal effect on free radical scavenging activity with the extracts prepared from leaves collected in October and November, and less significant IC50 was obtained from the extract prepared from leaves collected in August (5.63 mg/mL). A negative correlation (r= -0.694) was observed in this study between the content of polyphenols and the IC50 necessary to get the half of its antioxidant maximal effect. The high correspondence between the maximum values of polyphenols, flavonoids, carbohydrates and proteins in October and November, revealed a close relationship between these metabolites found in the extract of T. testudinum. Our hypothesis about the annual variation in the concentration of these metabolites was validated; and these results will support the correct harvesting of T. testudinum leaves for biotechnology and industrial purposes.

AB - Elevation gradient studies have strengthened the evaluation of changes in richness and composition of bird assemblages. They also provide information on environmental variables that determine bird distribution, and the variables that define their population structure. Our aim was to describe their variation through an elevational cline in Southern Nayarit, Mexico. To analyze the behavior of richness across the gradient, we gathered information through point counts in nine elevational intervals (300 m from each other) from sea level to 2 700 m of elevation. With a standardized sampling effort, we produced rarefaction curves and analyzed changes in species composition by hierarchical classification using the TWINSPAN technique. In order to identify variables associated with richness changes, we examined the effect of precipitation and habitat structure via regression trees. An analysis of nonmetric multidimensional scaling (NMDS) was implemented with the purpose to determine if the changes in composition correspond to changes in vegetation types. Species richness varied significantly across the gradient: high in the lower parts of the gradient, reached its peak in the middle, and decreased monotonically with elevation. Species responded to changes in the cline and were grouped in three elevational zones. Analyses suggest that changes in richness and species composition are influenced by vegetation, its structure and precipitation regime, as well as various aspects related to habitat features and disturbance. These aspects should be taken into account in order to design appropriate strategies for the conservation of the birds of Nayarit. PMID- 29465918 TI - Large mammal community composition and density under a disturbance gradient in Northeast Costa Rica. AB - Large mammal communities, integral components of Neotropical ecosystems, are increasingly threatened by habitat fragmentation and degradation due to anthropogenic pressures and climate change. Lowland Neotropical palm forests harbor diverse mammal communities, including threatened and endangered species. We monitored three transects in the Barra del Colorado Wildlife Refuge in Northeast Costa Rica from February 2014 until April 2015 documenting large terrestrial mammal and primate detections. Following established large mammal survey methodology, each transect was walked weekly alternating between early morning and late afternoon to maximize detection. The three transects represent three levels of anthropogenic disturbance with highest disturbance at the Cerro, followed by Cano Palma Biological Station (CPBS), and lowest levels in Tortuguero National Park (TNP). Overall we found higher diversity and increased presence of endangered species in TNP and the lowest diversity and lower presence of those species in the Cerro. Overall we detected 25 species; 19 at the Cerro, 22 in TNP and 23 at CPBS. TNP had the highest diversity as calculated by Simpson index (28.3) followed by CBPS (27.9), and the Cerro had the lowest diversity of mammals (2.27). The most influential species driving the differences of communities between the three transects included the white-lipped and collared peccaries, which were both present in higher densities in transects with lower disturbance and higher levels of protection, and domestic dogs which were present in higher densities at the Cerro. This study has documented baseline densities of large mammal communities in the wildlife refuge which can be used as preliminary data for future comparisons. As development is continuing in the region, including construction of a tourist trail at the Cerro, a continued monitoring is recommended to understand the effect of development on mammal communities. PMID- 29465919 TI - Seedling growth and survival of five tree species in secondary forests and adjacent pastures in the montane rain forests of Southern Costa Rica. AB - Successful forest restoration in tropical environments is limited by the paucity of studies on the initial establishment and early survival requirements of seedlings of most native tropical tree species under disturbed conditions. Here, we evaluated the initial growth responses and the regeneration potential of seedlings of five tree species native to Costa Rica (Hasseltia floribunda, Inga densiflora, Persea americana, Tapirira mexicana and Trichilia pittieri). Seedlings were grown in secondary forests and adjacent open pastures under contrasting conditions of light availability. We quantified seedling growth, survival and herbivory from August 2010 to August 2011 on a monthly basis, and measured differences in leaf mass per area (LMA) at the end of the experiment. We found significant variation in growth responses between the understory of secondary forests and pastures. Growth in height was highest in pastures across all species, with I. densiflora, P. americana and T. mexicana showing the most striking differences. In contrast, H. floribunda and T. pittieri did not show differences in diameter growth between environments. Except for T. mexicana, herbivory increased throughout the experiment in all the species. Herbivory increased faster in pastures for H. floribunda and T. pittieri and showed higher rates in the forest understory for I. densiflora and P. americana. Seedling survival showed significant differences for all species across environments. Survival of H. floribunda and I. densiflora was higher in secondary forests, whereas the other species showed higher survival in pastures. Leaf mass per area showed higher values in the pastures across all species, it suggests that individuals exposed to high light conditions had great photosynthetic rate and great leaf construction capacity. Due to their rapid growth and high survival, I. densiflora and T. mexicana showed great potential to restore abandoned pastures and secondary forests. Increasing our knowledge on the response of seedlings under disturbed conditions in tropical ecosystems is critical for improving the restoration of altered environments by matching the ecological amplitude of native species with specific environmental conditions.

AB - The endangered species Strombus gigas is a marine gastropod of significant economic importance through the Greater Caribbean region. In contrast to phenotypic plasticity, the role of genetics on shell variations in S. gigas has not been addressed so far, despite its importance in evolution, management and conservation of this species. This work used geometric morphometrics to investigate the phenotypic variation of 219 shells of S. gigas from eight sites of the Colombian Southwest Caribbean. Differences in mean size between sexes and among sites were contrasted by analysis of variance. Allometry was tested by multivariate regression and the hypothesis of common slope was contrasted by covariance multivariate analysis. Differences in the shell shape among sites were analyzed by principal component analysis. Sexual size dimorphism was not significant, whereas sexual shape dimorphism was significant and variable across sites. Differences in the shell shape among sites were concordant with genetic differences based on microsatellite data, supporting its genetic background. Besides, differences in the shell shape between populations genetically similar suggest a role of phenotypic plasticity in the morphometric variation of the shell shape. These outcomes evidence the role of genetic background and phenotypic plasticity in the shell shape of S. gigas. Thus, geometric morphometrics of shell shape may constitute a complementary tool to explore the genetic diversity of this species. PMID- 29465921 TI - Permanent germinal epithelium and reproductive cycle of Atractosteus tropicus (Lepisosteiformes: Lepisosteidae) males, Tabasco, Mexico. AB - The tropical gar A. tropicus plays an important ecological role as it regulates other fish stocks in different water bodies in Southeastern Mexico. Nevertheless, wild populations are declining, and one conservation alternative is the aquaculture production and basic knowledge of reproductive biology; for males, this requires the study of germ and somatic structures of testes, to characterize the reproductive cycle, and to provide basic knowledge for exploitation and conservation models and strategies. With this aim, a total of 24 males with an average Lp = 47.2 cm were collected from wild populations from the Laguna Pomposu, municipality of Jalpa de Mendez (18 degrees 19' - 93 degrees 01'12" W), Tabasco, Mexico. Fish were collected with a trawl net and were transported live to the Tropical Aquaculture Laboratory, Division Academica de Ciencias Biologicas (DACBiol), Universidad Juarez Autonoma de Tabasco (UJAT). Males were slaughtered by prolonged immersion in MS222. Testes samples were collected from each specimen and were processed using the standard histological procedures, that consisted of dehydration in an ascending ethanol series, xylol, embedding in paraffin, sectioning at 7 um, and staining with hematoxylin-eosin (HE). The diameter of 20 seminiferous tubules (Tse), height of germinal epithelium (Egl), gonadosomatic index (IGS) and gonad volume (gV) were determined monthly. Based on morphometric and morpho-physiological characteristics, the testes consisted of a network of anastomosed tubules with non-restricted cystic spermatogenesis, and a permanent germinal epithelium. This is the first report of a permanent germinal epithelium in A. tropicus. Five reproductive classes were histologically identified: Class I Regressed; Class II Early Maturation; Class III Mid Maturation; Class IV Late Maturation; Class V Regression. Monthly GSI, gV and Tse values were lower in January and February, the testis showed spermatozoa remains and a regenerating discontinuous germinal epithelium. In March spermiogenesis increased and proliferation of spermatogonia decreased. Male tropical gar followed a seasonal reproductive cycle, indicated by the monthly variation of the reproductive classes and the reproductive season processes observed, and for which temperature and rainfall seem to stimulate reproductive activity and spermiation. PMID- 29465940 TI - [Evaluation of PAE and AE for identifying generalized tracks using snakes in Hidalgo, Mexico]. AB - One of the most important concepts in Panbiogeography is the generalized track, which represents an ancestral biota fragmented by geological events that can be recovered through several methods, including Parsimony analysis of endemicity (PAE) and endemicity analysis (EA). PAE has been frequently used to identify generalized tracks, while EA is primarily designed to find areas of endemicity, but has been recently proposed for identifying generalized tracks as well. In this study we evaluated these methods to find generalized tracks using the distribution of the 84 snake species of Hidalgo. PAE found one generalized track from three individual tracks (Agkistrodon taylori, Crotalus totonacus and Pliocercus elapoides), supported by 89 % of Bootstrap, and EA identified two generalized tracks, with endemicity index values of 2.71-2.96 and 2.84-3.09, respectively. Those areas were transformed to generalized tracks. The first generalized track was retrieved from three individual tracks (Micrurus bernadi, Rhadinaea marcellae and R. quinquelineata), and the second was recovered from two individual tracks (Geophis mutitorques and Thamnophis sumichrasti). These generalized tracks can be considered a unique distribution pattern, because they resembled each other and agreed in shape. When comparing both methods, we noted that both are useful for identifying generalized tracks, and although they can be used independently, we suggest their complementary use. Nevertheless, to obtain accurate results, it is useful to consider theoretical bases of both methods, along with an appropriate choice of the size of the area. Results using small grid size in EA are ideal for searching biogeographical patterns within geopolitical limits. Furthermore, they can be used for conservation proposals at state level where endemic species become irreplaceable, and where losing them would imply the extinction of unique lineages. PMID- 29465941 TI - [Effects of human disturbance on the population dynamics of Ocypode quadrata (Decapoda: Ocypodidae) in beaches of the Mexican Caribbean]. AB - The ghost crab Ocypode quadrata is a relevant species in the Western Atlantic beaches, and has been proposed as an indicator of human impact in these ecosystems. Eventhough some studies have covered various aspects of its natural history, no evaluations on the effects of human disturbance on its population dynamics have been made. This work compared the abundance, growth, and mortality of O. quadrata in two disturbed beaches (Aventuras and Majahual) and two preserved beaches (Xcacel and Puerto Angel) from the Mexican Caribbean. For this, nine samplings were made on each beach (every two to three months) between March 2013 and November 2014. Crabs were collected manually by three people, during the night first hours and for one hour, and a total area of 9 000 m2 per beach. The crabs were measured, weighed, and separated into three groups: juvenile, male and female; while abundance was estimated by the number of collected crabs, and growth parameters were estimated using length frequencies. A total of 1 047 crabs were sampled in the four beaches; a higher crab abundance was found in the preserved beaches, but significant differences were only found between Puerto Angel and Majahual (Tukey, p<0.05). The adult-juvenile ratio was 1:1 in Xcacel and Aventuras, while in Majahual, more juveniles than adults were collected; and Puerto Angel had more adults than the juveniles. The size structure at Xcacel ranged from 4-32 mm, but in the rest of the beaches the minimum size was 5 mm. The maximum size at Aventuras, Majahual and Puerto Angel were 27 mm, 25 mm and 30 mm, respectively. The modal progression analysis of length's pooled data, revealed the presence of at least two groups of ages in all beaches. For all beaches, individuals smaller than 10 mm length were collected in almost all sampling months, indicating a continuous recruitment throughout the year. The length-weight relationship of the ghost crab was found isometric in the two preserved beaches, and negative allometric at the two impacted beaches. Crabs from Puerto Angel showed the highest body condition (Tukey, p<0.05). K-values ranged from 0.6-0.97/year and Linfinity from 29.0 mm to 33.6 mm with higher values for the two preserved beaches. The highest mortality values were found in Xcacel and Aventuras. In the disturbed beaches, the destruction of the dunes, the mechanical cleaning and the removal of organic matter, seem to be the main causes that lead to a low abundance of crabs, their slower growth and higher mortalities. However, in the best preserved beaches, biological interactions appear to be the most important aspects in regulating the population dynamics of this species. These results supported the information that the ghost crab is a good indicator of human disturbance, and its population changes were clearly measurable and comparable among protected and impacted beaches; these results are also relevant for the management of sandy beaches in the Mexican Caribbean. PMID- 29465942 TI - [Reproductive aspects of Pomacea flagellata (Mollusca: Ampullariidae) at Bacalar lagoon, Quintana Roo, Mexico]. AB - The freshwater snail Pomacea flagellata is native from Southeastern Mexico. Studies about this species are scarce and none has treated their reproduction. This snail has been exploited at Bacalar lagoon for many years, leading to a significant decrease in their abundance and currently, a permanent ban was proposed by the government. This work aimed to assess the temporal variations of mating frequency and the abundance of egg clutches of P. flagellata at Bacalar lagoon, as well as their relation with snails density and environmental variables. Sampling was done during the three climatic seasons: Rainy (July, August and September/2012), North or Cold fronts (December/2012 and January and February/2013) and Dry (March, April and May/2013) in 12 sampling stations located along the Bacalar lagoon. On each station a transect of 100 m length was set parallel to the edge, and the number of fresh egg clutches (pink color) laid over vegetation, rocks or manmade structures, were counted. In the water, three 50 x 2 m transects were set and the number of snails were counted as well as the mating frequency. Density of snails varied significantly among seasons, decreasing from the rainy to the dry season. There were no significant differences of snail abundance among months, nested in climatic seasons (ANOVA, p>0.05). During the rainy season the mating frequency was significantly higher than in the Norths, meanwhile in the dry season no mating were registered (Kruskal-Wallis, p?0.05). Eggs clutches appeared from July to March. Density of egg clutches presented no differences between the Rainy and the North seasons (2.72 and 2.93 clutches/m, respectively), nonetheless during the dry season abundance of egg masses was significantly lower (0.1 clutches/m) (H, p?0.05). Mating frequency was related with snail abundance (rs= 0.26; p<0.05) and water temperature (rs= 0.34; p<0.05) and the abundance of egg masses is related with snail abundance (rs= 0.46; p<0.05). In general, we observed that reproductive activity of P. flagellata at Bacalar lagoon is related with the warmer months and with higher rainfall. This finding is relevant to support the management of this resource in the region, so that to implement any management arrangement they must be aware that a temporal ban is necessary during the reproductive season at least. PMID- 29465943 TI - Water absorption and method improvement concerning electrical conductivity testing Acacia mangium (Fabaceae) seeds. AB - Acacia is an important forest species of rapid growth whose seeds have tegument dormancy. In this work it was intended to characterize water absorption pattern after seed dormancy break, and to determine the amount of water, container size and the need of breaking the tegument dormancy, as to perform electrical conductivity test in small and large seeds of Acacia mangium (Fabaceae). The seeds were collected from 10, 8 and 6 years old trees established in poor yielding-capacity soils on savannah areas of Roraima, Brazil; seeds were classified in six lots concerning to seed size and tree age. Germination tests (50 seeds and four replications per lot) were carried out on germitest(r) paper maintained on gerbox at 25 degrees C. Imbibition was verified by seed weighing at different times (0, 2, 5, 8, 12, 16, 24, 36, 48, 60, 72, 84, 96 and 120 hours). The electrical conductivity test consisted of three experiments, distinguished by the amount of water used and by the container size in which seeds were immersed. Seeds of A. mangium coming from 10 years old trees presented increased germination percent and germination speed than seeds of six-year old trees. Small seeds presented increased in electrical conductivity and water absorption until 120 hours when compared to large seeds. The immersion of seeds of A. mangium in 40 mL of distilled water into 180 mL plastic containers, after dormancy break, it is indicated for the determination of electrical conductivity test. The ratio of electrolytes by seed mass, after 24 hours of immersion in water, turns electrical conductivity test more accurate concerning A. mangium seeds. PMID- 29465944 TI - Using indigenous knowledge to link hyper-temporal land cover mapping with land use in the Venezuelan Amazon: "The Forest Pulse". AB - Remote sensing and traditional ecological knowledge (TEK) can be combined to advance conservation of remote tropical regions, e.g. Amazonia, where intensive in situ surveys are often not possible. Integrating TEK into monitoring and management of these areas allows for community participation, as well as for offering novel insights into sustainable resource use. In this study, we developed a 250 m resolution land-cover map of the Western Guyana Shield (Venezuela) based on remote sensing, and used TEK to validate its relevance for indigenous livelihoods and land uses. We first employed a hyper-temporal remotely sensed vegetation index to derive a land classification system. During a 1 300 km, eight day fluvial expedition in roadless areas in the Amazonas State (Venezuela), we visited six indigenous communities who provided geo-referenced data on hunting, fishing and farming activities. We overlaid these TEK data onto the land classification map, to link land classes with indigenous use. We characterized land classes using patterns of greenness temporal change and topo hydrological information, and proposed 12 land-cover types, grouped into five main landscapes: 1) water bodies; 2) open lands/forest edges; 3) evergreen forests; 4) submontane semideciduous forests, and 5) cloud forests. Each land cover class was identified with a pulsating profile describing temporal changes in greenness, hence we labelled our map as "The Forest Pulse". These greenness profiles showed a slightly increasing trend, for the period 2000 to 2009, in the land classes representing grassland and scrubland, and a slightly decreasing trend in the classes representing forests. This finding is consistent with a gain in carbon in grassland as a consequence of climate warming, and also with some loss of vegetation in the forests. Thus, our classification shows potential to assess future effects of climate change on landscape. Several classes were significantly connected with agriculture, fishing, overall hunting, and more specifically the hunting of primates, Mazama americana, Dasyprocta fuliginosa, and Tayassu pecari. Our results showed that TEK-based approaches can serve as a basis for validating the livelihood relevance of landscapes in high-value conservation areas, which can form the basis for furthering the management of natural resources in these regions.

AB - The ecosystems fragmentation is one of the anthropic phenomena with highest impact at global level and the edge effect causes that only the fragments interior conserve their original biotic and abiotic characteristics. Lichens are organisms especially susceptible to environmental variability, what could be useful for bio-indication of edge effect. In this work, we evaluated the edge effect in two fragments of Polylepis quadrijuga in the Paramo de la Rusia (Boyaca Colombia) to determine if there is an edge effect on distribution of lichens associated to P. quadrijuga and their chlorophyll content. We used three transects of 70 m across the matrix-edge-interior gradient in each fragment. We chose nine phorophytes per transect to measure the environmental variables: photosynthetically active radiation, relative humidity and air temperature, and the biological variables: richness and cover per species. Besides, we employed the species that were present in all the three zones of the gradient to quantify the content of chlorophylls a and b, and determine if there are changes in the ratio of chlorophylls a/b that could suggest physiological plasticity as a response to the edge effect. Our results showed that fragment 2 had a higher edge exposition because of its high relation perimeter/area, allowing to an environmental homogenization and lose of biodiversity in relation with fragment 1. Overall, we found 55 differentially distributed species in relation with the fragments and the matrix-edge-interior gradient. The interior of fragment 1 was the most conserved zone, harboring a composition different in more than 40 % to the composition of any other zone. We classified the lichens according with their habits: gelatinous, fruticose, crusty or foliose, but we did not find any relationship between the habit distribution and the edge effect. Six species of wide distribution showed changes in the chlorophyll content along the matrix-edge interior gradient, what is an evidence of physiological plasticity to edge effect. It was also possible to distinguish between species with preference to warmer environment and species with preference to more humid and sufficiently irradiated places. We concluded that some species of lichens could have an important potential as bio-indicators of fragmentation in the paramo.

AB - The light environment in the understory of cloud forests is highly heterogeneous and determined by species composition, canopy structure, site conditions, and seasonality. This study was carried out at San Eusebio cloud forest, Venezuela (2 300 - 2 500 masl). The impact of canopy structure variations on understory light availability was estimated in the dry (December-February) and rainy (March November) seasons, in sites under continuous canopy cover and gaps of various sizes. Hemispherical photographs were taken to estimate the percentage of canopy openness, leaf area index, percentages of transmitted direct and diffuse light, and duration and frequency of sunflecks. A light index was calculated from the relative proportions of direct and diffuse light transmitted to the understory. For most variables, there were significant differences between seasons, as well as among different gap sizes and under closed canopy. The light index was low (0.25 to 26 of a maximum = 100), even for the largest gaps, indicating a highly shaded light environment, especially beneath closed canopy in the rainy season. Patterns and interactions among factors were analyzed (gaps vs. continuous canopy, gap sizes, location within the gaps, and seasonality) with a mixed effects repeated measures Anova design. Results showed that the amount of light reaching the understory is low in both gaps and closed canopy. However, small but significant differences in light availability existed for both seasonality and magnitude of the perturbations. These differences could contribute to explain the dynamics of tree species regeneration in this forest. The knowledge of the factors conditioning light availability in the understory where tree regeneration begins is crucial in cloud forests because of energetic limitations in this ecosystem, and might be essential for future restoration and conservation plans concerning the preservation of the diversity and integrity of these forests.

AB - The fine roots play an important role in the acquisition of water and minerals from the soil, the global carbon balance and mitigation of climate change. The dynamics (productivity and turnover) of fine roots is essential for nutrient cycling and carbon balance of forest ecosystems. The availability of soil water and nutrients has significantly determined the productivity and turnover of fine roots. It has been hypothesized that fine roots dynamics increases with the availability of soil resources in tropical forest ecosystems. To test this hypothesis in tropical rainforests of Choco (ecosystems with the highest rainfall in the world), five one-ha permanent plots were established in the localities of Opogodo and Pacurita, where the productivity and turnover of fine roots were measured at 0-10 cm and 10-20 cm depth. The measurement of the fine root production was realized by the Ingrowth core method. The fine root turnover was measured like fine roots production divided mean annual biomass. In addition, soil fertility parameters (pH, nutrients, and texture) were measured and their association with productivity and turnover of fine roots was evaluated. It was found that the sites had nutrient-poor soils. The localities also differ in soil; Opogodo has sandy soils and flat topography, and Pacurita has clay soils, rich in aluminum and mountainous topography. In Opogodo fine root production was 6.50 +/- 2.62 t/ha.yr (mean +/- SD). In Pacurita, fine root production was 3.61 +/- 0.88 t/ha.yr. Also in Opogodo, the fine root turnover was higher than in Pacurita (1.17 /y and 0.62 /y, respectively). Fine root turnover and production in the upper soil layers (10 cm upper soil) was considerably higher. Productivity and turnover of fine roots showed positive correlation with pH and contents of organic matter, total N, K, Mg, and sand; whereas correlations were negative with ECEC and contents of Al, silt, and clay. The percentage of sand was the parameter that best explained the variations of fine root production. The fine root turnover was negatively explained by soil Al availability. Results suggested the increase of fine root dynamics with soil fertility at a local scale, which also indicates that under the oligotrophic conditions of soils in tropical rainforests, fine roots tend to proliferate rapidly in small patches of soil rich in sand and nutrients. PMID- 29465948 TI - A living fossil Tetrapus fig wasp (Hymenoptera: Agaoninae) developing in extant Neotropical fig species (Moraceae: Ficus, section Pharmacosycea). AB - It has been assumed that Tetrapus female wasps (Agaonidae s.s.), the pollinators of the figs of the New World, section Pharmacosycea, are mainly characterized by the presence of one mandibular appendange only, and that it is the most ancestral clade of extant Agaonidae s.s., and the males are tetrapodous. The main objective of this work was to study five Tetrapus morphotypes, whose females have two mandibular appendages and the males are hexapodous, their fig host association and phylogenetic position to the family Agaonidae. The question of which group of fig pollinating wasps and associated figs are the sister to the rest of the pollinating agaonids, and figs respectively remain open. I report a group of New World extant Tetrapus morphotypes (Agaonidae: Agaoninae) provisionally assigned to Hexapus subg. nov. in preparation. Currently, Tetrapus appears as the sister taxon to all other fig pollinating taxa. Howeveer, morphologically, ecologically, geographically and historically Hexapus seems to be the ancestral clade of the extant Agaoninae. Hexapus morphotypes develop in fig species of subsection Petenenses (section Pharmacosycea). In the known extant Tetrapus, the females have one mandibular appendage and the males have reduced one or two short-lobe atrophied non-functional midlegs (tetrapodous). Hexapus females have two free mandibular appendages, and the males have five segmented functional mid-legs (hexapodous). Molecularly Hexapus seems to be the ancestral clade of extant Agaoninae; e.g., a Tetrapus sp. of Ficus crassivenosa was placed by other author as the ancestral clade of 101 wasp species, representing 19 worldwide Agaoninae genera, including four Tetrapus species. In Tetrapus sp. of Ficus crassivenosa, the female has two mandibular appendages and the male is hexapodous. The females of T. apopnus and T. delclosi, preserved in Early to mid-Miocene amber from the Dominican Republic, also have two mandibular appendages and the general morphology of extant Hexapus. I suggest that Hexapus stands up as a living fossil and the sister clade of Tetrapus s.s. The presence of extant Hexapus; as well as extant Tetrapus and their fig host species, especially in South America supports a Southern Gondwanaland origin for both of them, but not a trans-Pacific migrating connection with tropical America for section Pharmacosycea (the host of Tetrapus and Hexapus), a long oceanic dispersal, high levels of stem extinction of Tetrapus or Atlantic land connections, as proposed by other authors. However, lastly it has been assumed that figs and their pollinators arose simultaneously in Eurasia during early Tertiary and spread southwards from it. Most of the morphological and molecular studies of the fig biology of Agaoninae and Ficus, did not include Hexapus morphotypes and their fig hosts, and assumed that Tetrapus is the most ancestral clade of the extant fig pollinating wasps.

AB - The effect of insecticides on bees has gained great attention, however, there are few studies that explore this issue on Neotropical bees. Bombus atratus is a neotropical species broadly distributed in Colombia and is considered an important pollinator of both Andean ecosystems and agroecosystems. However, as for many wild bees species, the effect of insecticides on B. atratus is unknow. In this study we determined the acute median lethal dose (LD50) of commercial formulations of insecticides Imidacloprid, Spinosad and Thiocyclam hydrogen oxalate, widely used in Colombia to control several pests of important crops. The LD50 was carried out by oral and contact routes, following and modifying the EPPO and OECD guidelines to perform LD50 on A. mellifera. We evaluated five doses for each route and insecticide, in a total of 25 medium-size workers for each dose by duplicate. Mortality was registered at 24, 48 and 72 hours after the experiment; and data were analyzed with the Probit regression model. For Imidacloprid, contacts and oral LD50 were 0.048 ug/bee and 0.010 ug/bee, respectively. For Thiocyclam hydrogen oxalate, topical and oral LD50 were 0.244 ug/bee and 0.056 ug/bee, respectively. For Spinosad, the oral LD50 corresponded to 0.28 ug/bee; it was not possible to establish the LD50 for the contact route. The Hazard Quotient (HQ) and Index of Relative Toxicity indicated that all three active ingredients are highly toxic. We discussed the risk of the insecticides use on B. atratus, considering their chemical nature. PMID- 29465950 TI - Total protein composition of young and adult Biomphalaria alexandrina snails with different compatibilities to Schistosoma mansoni infection. AB - Schistosomiasis remains a disease of major global public health concern since it is a chronic anddebilitating illness. The widely distributed Schistosoma mansoni that causes intestinal schistosomiasis representsa great threat. Its world-wide distribution is permitted by the broad geographic range of the susceptible species ofits intermediate host, Biomphalaria, which serves as an obligatory host for the larval stage, at which humans getinfected. The objectives were to identify the proteins responsible for the snails' compatibility outcome throughdifferentiation between the total proteins among Biomphalaria alexandrina snails at different ages. The workwas conducted on snails that differ in age and genetic backgrounds. Four subgroups (F1) from the progeny ofself-reproduced susceptible and resistant snails (F0) were studied. Infection rates of these subgroups (youngsusceptible, adult susceptible, young resistant and adult resistant) were 90 %, 75 %, 40 % and 0 %, respectively.Using Sodium Dodecyl Sulphate Polyacrylamide Gel electrophoresis (SDS-PAGE), differences in proteinexpression were evaluated between adult and young snails of different subgroups. Dice similarity coefficient wascalculated to determine the percentage of band sharing among the experimental subgroups. The results showedthat the combination of similarities between age and compatibility status of the snails, lead to the highest similaritycoefficient, followed by the combination of similarities of both genetic origin and age, even though theydiffer in the compatibility status. On the other hand, the differences in the genetic background, age and compatibilitystatus, lead to the least similarity index. It was also found that the genetic background in young snailsplays a major role in the determination of their compatibility, while the internal defense system has the upperhand in determining the level of adult compatibility. In conclusion, the findings of the present work highlightthe great impact of the snail age in concomitance with the genetics and the internal defense in the determinationof B. alexandrina/S.mansoni compatibility. Future works are recommended, as further characterization of theshared protein bands among the studied subgroups is needed to clarify their role in host-parasite relationship. PMID- 29465951 TI - Anaerobic microbiota: spatial-temporal changes in the sediment of a tropical coastal lagoon with ephemeral inlet in the Gulf of Mexico. AB - Sulfate-reducing bacteria (SRB) and methanogenic archaea (MA) share common niches in coastal sediments during the terminal phases of the anaerobic mineralization of organic matter. The purpose of this study was to analyze the spatial - temporal variation of SRB and MA in the sediments of a tropical coastal lagoon with ephemeral inlet (La Mancha, Veracruz, Gulf of Mexico) and its relationship with environmental changes. A total of 24 sediment samples were collected during the dry (April, May), rainy (July, September) and Northern (November, February) seasons in the period 2013-2014. Microbiological analyses included the quantification of the viable SRB and MA with different substrates, as well as mineralization experiments to determine the effect of sulfate on acetate oxidation. The analyzed environmental variables in the sediments included: temperature, pH, Eh, salinity, sulfates, H2S, volatile solids, carbohydrates, and granulometric characteristics. Major changes occurred between the dry and rainy seasons. During the dry season, sulfate-reducing abundance was significantly greater with lactate (8.3x105 - 1.2x107 cells / g) and propionate (1.8x105 - 6.6x106 cells / g) as substrates, while the MA that use methanol were dominant (4.2x105 - 9.1x106 cells / g). In contrast, during the rainy season, hydrogenophylic (2.6x105 - 8.3x106 cells/g) and acetoclastic (5.4x105-6.4x106 cells / g) MA increased significantly and SRB decreased in the analyzed substrates. An apparent competition for acetate was observed, with a greater oxidation in the media with sulfates in the dry season (0.06 mM acetate / g sediment / day), and a greater oxidation in the media without sulfates in the rainy season (0.02 mM acetate / g sediment / day). SRB and MA were present throughout the sediment column, however SRB dominated in the first centimeters of the sediment while MA were abundant in deeper layers. In conclusion, SRB and MA together played a role in the mineralization of organic matter in the sediments of La Mancha lagoon, with sulfate-reduction dominating in the dry season (closed inlet) and methanogenesis during the rainy season (open inlet). Changes in rainfall and river input in this lagoon significantly affect salinity and sulfate content, the main factors that regulate the dynamics of SRB and MA in the sediments. PMID- 29465952 TI - One year weekly dynamics of limnological conditions and phytoplankton in Lake Bonilla, Costa Rica. AB - The detailed response of tropical lake phytoplankton to weather variations has been little studied, but it seems that composition varies in response to rain and wind variability over the course of the year. In order to gather more evidence on this variation, the weekly variability of phytoplankton composition was studied in Lake Bonilla, a low land (380 masl) 30 m deep tropical lake, from April 2010 to May 2011. Temperature variation at several depths was recorded automatically, and measurements of dissolved oxygen, water transparency, and nutrients were performed several times during the study period. The lake showed a warm monomictic pattern, with deep mixing occurring during the hemispherical winter, especially after a heavy rain period in December 2010. Phytoplankton was dominated by a few species: a colonial Cyanobacteria (Aphanocapsa sp., functional group F) and two colonial Chlorococcaceae (Botryococcus braunii and Eutetramorus tetrasporus, both in the functional group K). Their relative dominance shifted throughout the year, following changes in water column conditions in response to weather variations. Although changes in main functional groups indicate a shift in resource availability rather than energy, it was clear that attention should also be given to particular species adaptations beyond those used for establishing functional groups. PMID- 29465953 TI - Infectivity of Chordodes nobilii larvae (Gordiida: Nematomorpha). AB - The gordiids are freshwater representatives of the parasite phylum Nematomorpha that function asa link between aquatic and terrestrial ecosystems. In recent years, different ecotoxicologic studies have beenmade with the South-American gordiid species, Chordodes nobilii, that have demonstrated the capacity of thisgroup to act as a bioindicator of contamination. Despite the Gordiida's ecologic relevance, further studies arestill needed to elucidate different aspects of the biology of the class, and among those, the infective capacity,a parameter that can be evaluated by the infection index mean abundance (IIMA). A knowledge of the intrinsicvariability in the infective capacity of C. nobilii would warrant priority in order to establish, the range ofacceptable responses for normal or standard conditions in the laboratory, and, to compare the criteria amongdifferent assays. The objective of this study was to establish a baseline value for the infective capacity for C.nobilii larvae, under controlled laboratory conditions, by employing the IIMA as the evaluation parameter. Tothat end, we analyzed the infective capacity of C. nobilii larvae that had hatched from different strings of eggslaid in the laboratory by a total of 12 females. The C. nobilii adults were collected from streams within theArgentina Sauce Grande basin, between 2006 and 2009. Once in the laboratory, after mating, the females wereplaced in individual containers for oviposition. The egg strings obtained from each female were cut in 3 mmlong segments; and when free larvae were observed, the segments (N= 90) were placed together with 30 Aedesaegypti larvae for evaluation of the gordiids' infective capacity. After 72 h, the mosquito larvae were observedby microscopy in order to quantify the C. nobilii larvae in body cavities. The IIMAs were calculated as the totalnumber of C. nobilii larvae present divided by total number of A. aegypti larvae examined. For analysis of theIIMAs obtained, the data were grouped according to the female who made the original ovoposition. Our resultsenabled the corroboration of an ample range of responses in the infective capacity of this species, a characteristicthat would normally be linked to the progenitors originating the hatch. Because this relationship prevents theestablishment of a baseline for making comparisons among assays with gordiids, through the IIMA as a responseparameter, we recommend expressing the IIMA values in each assay relative to their respective controls. Thesefindings also provide evidence for the greater success in infections by certain members of the progeny over others.Finally, on the basis of the results obtained from this study, we stress the relevance of the use of the IIMAas a decisive aspect to be considered in different studies on the biology of Gordiida. PMID- 29465954 TI - Sexual and vegetative propagation of the medicinal Mexican species Phyllonoma laticuspis (Phyllonomaceae). AB - Phyllonoma laticuspis leaves are used in Carrizal de Bravo, Guerrero, Mexico, to heal skin lesions such as injuries and smallpox sequelae and to treat diabetes mellitus type 2, and organic extracts of these leaves have been reported to exert antibacterial effects. High demand of P. laticuspis as a medicinal plant has decreased its natural populations, and propagation of the species has not yet been reported. Therefore, the purpose of this study was to assess the vegetative propagation of the species through cutting and air layering, as well as its sexual propagation in a preserved population. For this, concentrations of 1 000, 4 000 and 6 000 ppm of a commercial root enhancer, with indole butyric acid (IBA), and a control treatment without IBA, were applied to the cuttings and air layers. Germination was evaluated under light and dark conditions using lots of freshly collected seeds and lots of seeds that had been stored for three months at 4 degrees C or 24 +/- 2 degrees C. All experiments were performed in a completely randomized design. The cuttings did not develop roots in any concentration, whereas 100 % of the air layers rooted, displaying vigorous roots in the presence of 4 000 ppm IBA, after four month of treatment application. Regarding germination, more than 60 % of the freshly collected seeds germinated, whereas less than 20 % of the seeds stored at 4 degrees C, and close to 50 % of the seeds stored at 24 +/- 2 degrees C germinated under light and dark conditions. No significant differences were observed between light and dark conditions, so they were categorized as indifferent photoblastic seeds. The observed moisture content of 13.5 % and germination behaviour as the response to cold storage, suggest that the resultant seed quality was intermediate. P. laticuspis propagation for short-term foliage production can be carried out in air layers, in populations with a high density of adult plants as a source of plant material and for the restoration of disturbed areas, in the same locality. On the other hand, large-scale seedling production, medium-term foliage production and preservation of species variability can be achieved using seeds.

AB - The oil industry has generated chronic oil spills and their accumulation in wetlands of the state of Tabasco, in Southeastern Mexico. Waterlogging is a factor that limits the use of remediation technologies because of its high cost and low levels of oil degradation. However, Leersia hexandra is a grass that grows in these contaminated areas with weathered oil. The aim of the study was to evaluate the bacteria density, plant biomass production and phytoremediation of L. hexandra in contaminated soil. For this, two experiments in plastic tunnel were performed with fresh (E1) and weathered petroleum (E2) under waterlogging experimental conditions. The E1 was based on eight doses: 6 000, 10 000, 30 000, 60 000, 90 000, 120 000, 150 000 and 180 000 mg.kg-1 dry basis (d. b.) of total petroleum hydrocarbons fresh (TPH-F), and the E2, that evaluated five doses: 14 173, 28 400, 50 598, 75 492 and 112 142 mg. kg-1 d. b. of total petroleum hydrocarbons weathered (TPH-W); a control treatment with 2 607 mg.kg-1 d. b. was used. Each experiment, with eight replicates per treatment, evaluated after three and six months: a) microbial density of total free-living nitrogen-fixing bacteria (NFB) of Azospirillum (AZP) and Azotobacter group (AZT), for viable count in serial plate; b) dry matter production (DMP), quantified gravimetrically as dry weight of L. hexandra; and c) the decontamination percentage of hydrocarbons (PDH) by Soxhlet extraction. In soil with TPH-F, the NFB, AZP y AZT populations were stimulated five times more than the control both at the three and six months; however, concentrations of 150 000 and 180 000 mg.kg-1 d. b. inhibited the bacterial density between 70 and 89 %. Likewise, in soil with TPH W, the FNB, AZP and AZT inhibitions were 90 %, with the exception of the 14 173 mg.kg-1 d. b. treatment, which stimulated the NFB and AZT in 2 and 0.10 times more than the control, respectively. The DMP was continued at the six months in the experiments, with values of 63 and 89 g in fresh and weathered petroleum, respectively; had no significant differences with the control (p<=0.05). The PDH reached values of 66 to 87 % both TPH-F and TPH-W at six months, respectively. These results demonstrated the ability the L. hexandra rhizosphere to stimulate the high NFB density, vegetal biomass production and phytoremediation of contaminated soils (with fresh and weathered petroleum), in a tropical waterlogging environment.

The morphological features and illustrations of immature stages of A. rugosus are presented. Notes about the biology and behavior were included. The nymphal and adult stages of A. rugosus were found in remnants of riparian vegetation of the mesophilous forest in La Antigua river basin, Veracruz, Mexico. Twelve sites in five localities were selected and the specimens were sampled in rainy (July) and dry (April) seasons of 2012. The samples were processed in Berlese-Tullgren funnel and Winkler. A total of 419 individuals, 320 adults and 99 nymphs of A. rugosus were revised. The size and coloration of the body and punctuation patterns the immature stages of A. rugosus, A. ficus, and A. morelensis are the main differences among these species. A. rugosus is a first record from Veracruz. PMID- 29465957 TI - [Effect of management on tree diversity in secondary vegetation in the Biosphere Reserve of Calakmul, Campeche, Mexico]. AB - The tropical dry forest (BTS) of Yucatan Peninsula has been managed forcenturies, but the relationship between these management efforts and their effects on trees diversity has not beenfully understood. The aim of this study was to evaluate the effect of forest management (thinning, harvestingand enrichment of species), in the structure of secondary vegetation derived from dry tropical forests, in twocommunities in Calakmul, Campeche, Southeast Mexico. We analyzed changes in the composition, speciesrichness, species diversity, and structure in secondary vegetation subject to following types of management: (1)secondary vegetation with beekeeping management (MA), secondary vegetation with forest management (MF),natural secondary vegetation (SM) and tropical dry forest (BTS). The species composition was similar betweensecondary vegetation managed and unmanaged. On the other hand, between managed secondary vegetation andBTS there were differences in species composition. Species richness was not different between all conditions.MA showed the lowest species diversity and presented higher average density (5 413+/ 770.26 ind.ha-1).MF hadlowest average density (3 289 +/- 1 183.60 ind.ha-1). BTS showed the highest average basal area (24.89 +/- 1.56m2.ha-1) regarding the other conditions. We concluded that is necessary to keep monitoring the managed areasto detect effects of management that may be adverse or favorable to conservation of floristic diversity of BTS. PMID- 29465973 TI - Impact of daily variable temperatures in life-history traits of tropical anurans. AB - Anuran embryos and tadpoles are daily exposed to wide thermal variations in their ponds, with maximum temperatures at midday. The aim of this research was to study the impact of three daily variable thermal environments (with maximum experimental temperatures between 10:00 and 16:00 hours), on the survival, developmental time and body size of metamorphs of four tropical anuran species from lowland habitats in Colombia. A total of 50 embryos (Gosner stage ten) to metamorphosis (Gosner stage 46) of Rhinella humboldti, Hypsiboas crepitans and Engystomops pustulosus were exposed to each one of the three daily variable temperature treatments: high temperature (mean = 27.5 degrees C; maximum temperature = 34 +/- 1 degrees C; range = 23-35 degrees C), medium temperature (25.5 degrees C; 29 +/- 1 degrees C; 23-30 degrees C), and low temperature (24 degrees C; 24 +/- 1 degrees C; 23-25 degrees C). For the other species, Espadarana prosoblepon, 40 embryos to metamorphosis were exposed to each one of the following thermal treatments: high temperature (mean = 22 degrees C; maximum temperature = 25 +/- 1 degrees C; range = 18-26 degrees C), medium temperature (20.5 degrees C; 22 +/- 1 degrees C; 18-23 degrees C), and low temperature (19 degrees C; 19 +/- 1 degrees C; 18-20 degrees C). For all species, the thermal variable environment with the highest temperature showed the greatest accumulated survival, reduced significantly the developmental time from embryos to metamorphs, and the snout-vent-length of metamorphs. Therefore, under field conditions where ponds are exposed to thermally variable environments, the highest temperatures may promote a decrease in the period of time to metamorphosis, and a positive increase for the anuran survival; nevertheless, extreme temperatures were also found in the microhabitat of the species studied, higher than their upper thermal limits reported, which suggest a vulnerable situation for them and other tropical anurans from similar habitats. PMID- 29465974 TI - Metal-Organic Framework-Derived Hollow Hierarchical Co3O4 Nanocages with Tunable Size and Morphology: Ultrasensitive and Highly Selective Detection of Methylbenzenes. AB - Nearly monodisperse hollow hierarchical Co3O4 nanocages of four different sizes (~0.3, 1.0, 2.0, and 4.0 MUm) consisting of nanosheets were prepared by controlled precipitation of zeolitic imidazolate framework-67 (ZIF-67) rhombic dodecahedra, followed by solvothermal synthesis of Co3O4 nanocages using ZIF-67 self-sacrificial templates, and subsequent heat treatment for the development of high-performance methylbenzene sensors. The sensor based on hollow hierarchical Co3O4 nanocages with the size of ~1.0 MUm exhibited not only ultrahigh responses (resistance ratios) to 5 ppm p-xylene (78.6) and toluene (43.8) but also a remarkably high selectivity to methylbenzene over the interference of ubiquitous ethanol at 225 degrees C. The unprecedented and high response and selectivity to methylbenzenes are attributed to the highly gas-accessible hollow hierarchical morphology with thin shells, abundant mesopores, and high surface area per unit volume as well as the high catalytic activity of Co3O4. Moreover, the size, shell thickness, mesopores, and hollow/hierarchical morphology of the nanocages, the key parameters determining the gas response and selectivity, could be well controlled by tuning the precipitation of ZIF-67 rhombic dodecahedra and solvothermal reaction. This method can pave a new pathway for the design of high performance methylbenzene sensors for monitoring the quality of indoor air. PMID- 29465975 TI - An Integrated Approach Based on a DNA Self-Assembly Technique for Characterization of Crosstalk among Combinatorial Histone Modifications. AB - Combinatorial histone post-translational modifications (HPTMs) form a complex epigenetic code that can be decoded by specific binding proteins, termed as readers. Their specific interplays have been thought to determine gene expression and downstream biological functions. However, it is still a big challenge to analyze such interactions due to various limitations including rather weak, transient, and complicated interactions between HPTMs and readers, the high dynamic property of HPTMs, and the low abundance of reader proteins. Here we sought to take advantage of DNA-templated and photo-cross-linking techniques to design a group of combinatorial histone PTM peptide probes for the identification of multivalent interactions among histone PTMs and readers. By use of trimethylation on histone H3K4 (H3K4me3) and phosphorylation on H3T3, we demonstrated that this approach can be successfully utilized for identification of the PTM crosstalk on the same histone. By use of H3K4me3 and acetylation on H4K16, we showed the potential application of the probe in the multivalent interactions among PTMs on different histones. Thus, this new chemical proteomics tool combined with mass spectrometry holds a promising potential in profiling of the readers of combinatorial HPTMs and characterization of crosstalk among multiple PTMs on histones and can be adapted for broad biomedical applications. PMID- 29465976 TI - Role of Gastropod Mucus in the Transmission of Angiostrongylus cantonensis, a Potentially Serious Neurological Infection. AB - Angiostrongylus cantonensis, the rat lungworm, is endemic to Hawaii. A recent increase in the number of cases has drawn intense local and national media attention. As a result there is an increased fear of acquiring the disease from local produce, which has the potential to adversely affect the income of local farmers. The most common means of transmission is by the ingestion of an infected intermediate host. Other modes of transmission have been suggested including infectious larvae being released into the mucus trail of gastropods. This literature review indicates that mucus trails from infected gastropods poses a minimal risk to humans. PMID- 29465977 TI - Potential Utility of Metal-Organic Framework-Based Platform for Sensing Pesticides. AB - The progress in modern agricultural practices could not have been realized without the large-scale contribution of assorted pesticides (e.g., organophosphates and nonorganophosphates). Precise tracking of these chemicals has become very important for safeguarding the environment and food resources owing to their very high toxicity. Hence, the development of sensitive and convenient sensors for the on-site detection of pesticides is imperative to overcome practical limitations encountered in conventional methodologies, which require skilled manpower at the expense of high cost and low portability. In this regard, the role of novel, advanced functional materials such as metal-organic frameworks (MOFs) has drawn great interest as an alternative for conventional sensory systems because of their numerous advantages over other nanomaterials. This review was organized to address the recent advances in applications of MOFs for sensing various pesticides because of their tailorable optical and electrical characteristics. It also provides in-depth comparison of the performance of MOFs with other nanomaterial sensing platforms. Further, we discuss the present challenges (e.g., potential bias due to instability under certain conditions, variations in the diffusion rate of the pesticide, chemical interferences, and the precise measurement of luminesce quenching) in developing robust and sensitive sensors by using tailored porosity, functionalities, and better framework stability. PMID- 29465978 TI - Weaker N-Terminal Interactions for the Protective over the Causative Abeta Peptide Dimer Mutants. AB - Knowing that abeta amyloid peptide (Abeta42) dimers are the smallest and most abundant neurotoxic oligomers for Alzheimer's disease (AD), we used molecular simulations with advanced sampling methods (replica-exchange) to characterize and compare interactions between the N-termini (residues 1-16) of wild type (WT-WT) and five mutant dimers under constrained and unconstrained conditions. The number of contacts and distances between the N-termini, and contact maps of their conformational landscape illustrate substantial differences for a single residue change. The N-terminal contacts are significantly diminished for the dimers containing the monomers that protect against (WT-A2T) as compared with those that predispose toward (A2V-A2V) AD and for the control WT-WT dimers. The reduced number of N-terminal contacts not only occurs at or near the second residue mutations but also is distributed through to the 10th residue. These findings provide added support to the accumulating evidence for the "N-terminal hypothesis of AD" and offer an alternate mechanism for the cause of protection from the A2T mutant.

These technological innovations are based on several factors, one of which is miniaturization. This was made possible also due to the discovery and synthesis of new materials with characteristics at the nanoscale that are designed for specific purposes. This "on purpose" approach, joined to the development of preparation and growth methods, has led to use of thin films rather than bulk materials in devices. Using thin films makes devices easier to produce, and using films for coating protects the devices and gives specific properties to surfaces. For several decades thin films, surfaces, and interfaces have been intensively investigated. Indeed, device performances rely on the optimized match of thin films of different natures, such as organic and inorganic semiconductors and metals for contacts. Surprisingly, in comparison, little attention has been devoted to the deposition of organic radicals on a substrate. This might be because these materials are considered not stable enough for evaporation. In this work, we demonstrate that it is possible to evaporate and deposit organic radicals onto well-defined surfaces under controlled conditions, without degradation. Using soft X-ray spectroscopies, performed also at synchrotrons, we investigate thin film processes, surfaces, and interfaces at the nanoscale, when organic radicals are deposited on metal and metal oxide surfaces. We suggest how to design organic radicals bearing in mind the thermodynamic factors that govern thin film stability, with the purpose of obtaining not only a chemically stable radical, but also stable thin films. We investigate the thermal and air stability of the deposited films, and we explore the influence of the surface/radical chemical bond and the role of surface defects on the magnetic moment at the interface. We find that organic radicals are physisorbed and keep their magnetic moment on inert and passivated surfaces such as Au(111) and Al2O3(1120) single crystals, SiO2, and ideal TiO2(110) single crystals, while defective sites such as oxygen vacancies or the presence of OH groups lead to chemisorption of the organic radicals on the surface with quenching of their magnetic moment. Our work shows that the use of X-ray based techniques represents a powerful approach to reveal the mechanisms governing complex interfaces, such as radical/metal and radical/metal-oxide, where it is important to describe both charge and spin behavior (spinterfaces). It also makes it possible to conceive new experiments to investigate the magnetic character of the thin films versus their structural properties, toward tuning the arrangement of the molecules in films. Controlling the molecular arrangement will give the opportunity to tune the mutual position and orientation of the molecules, that is, of the single magnetic moments in the films, "imprinting" their magnetic properties. A deep understanding of stable radical/inorganic spinterfaces may open the way to use radicals in solid state devices or as quantum bits with dedicated configurations, as proposed for other molecular quantum bits, and in spin-based electronics.

AB - Due to the critical role glycation plays in many serious pathological conditions, such as diabetes, it is of great significance to discover protein glycation at an early stage for precaution and prediction of the disease. Here, a method of reductive amination combining dimethylation (RAD) was developed for the quantification of early-stage glycated proteins. The quantitative analysis was first carried out by reducing the samples using NaBH3CN or NaBD3CN, resulting in a 1 Da mass shift and the stabilization of early-stage protein glycation. The two samples were then digested and isotopically dimethylated to achieve the mass shift of 4 m + 3 n ( m represents the number of N-termini and Lys residues, and n represents the number of glycated sites) between light- and heavy-labeled glycated peptides for quantification. Consequently, the false positive result can be removed according to the different mass shifts of glycated peptides and non glycated peptides. In quantification of glycated myoglobin, RAD showed good linearity ( R2 > 0.99) and reproducibility (CVs <= 1.6%) in 2 orders of magnitude (1:10-10:1). RAD was then applied to quantify the endogenous glycated proteins in the serum of diabetic patients, revealing significant differences in the glycation level between the patients with complicated retinal detachment and those without. In conclusion, RAD is an effective method for quantifying endogenous glycated proteins.

AB - Self-assembled micrometer-scale vesicles composed of lamellar phase forming amphiphiles are useful as chemical microreactors, as minimal artificial cells, as protocell mimics for studies of the origins of life, and as vehicles for the targeted delivery of drugs. Given their varied uses, discovery of a universal mechanism that is simple, rapid, and that produces vesicles from a large variety of amphiphiles with different chemical and physical properties at high yield is extremely desirable. Here we show that cellulose, in the form of cellulose paper, facilitates the assembly of membranous vesicles 5-20 MUm in diameter from scientifically and technologically important amphiphiles of diverse chemical structures and functionality such as fatty acids (fatty acid vesicles), amphiphilic diblock copolymers, and amphiphilic triblock copolymers (polymersomes). Assembly of vesicles occurred within 90 min of placing the amphiphile-coated cellulose paper into aqueous solutions. Varying thermal and chemical conditions, however, are required for the high-yield assembly of vesicles from the different amphiphiles. The vesicles, when attached to cellulose fibers, have membranes that remain unsealed. This topological characteristic of the vesicles grown on paper allowed the scalable separation of the process of growth from the process of loading cargo (temporally decoupled growth and loading). We demonstrate a temporally decoupled process to rapidly produce large quantities of protein-loaded polymersomes on the benchtop by using high temperatures to accelerate the growth of the polymersomes and subsequently milder temperatures during diffusive loading of the protein cargo.

AB - To improve the health of patients with end-stage renal disease, there is a clear need for slow, continuous hemodialysis, and the primary barrier to a wearable device is the requirement of a large reservoir of dialysate. We describe an electrokinetic means of producing dialysate from the excess fluid extant in the peripheral blood of patients undergoing therapy. A critical feature of this process is the retention of essential components of blood, especially serum albumin. In progress toward this goal, we demonstrate the separation of charged from neutral species in blood plasma at a branched microchannel junction by ion concentration polarization (ICP). Further, we introduce a method that reduces the opportunity for damage to proteins and prevents electrode biofouling. The present approach results in as high as 99.7% retention of albumin and successful separation of neutral metabolites and excess fluid to be utilized as a precursor to dialysate.

AB - Polysaccharide characterization posts the most difficult challenge to available analytical technologies compared to other types of biomolecules. Plant polysaccharides are reported to have numerous medicinal values, but their effect can be different based on the types of plants, and even regions of productions and conditions of cultivation. However, the molecular basis of the differences of these polysaccharides is largely unknown. In this study, direct analysis in real time mass spectrometry (DART-MS) was used to generate polysaccharide fingerprints. Large saccharides can break down into characteristic small fragments in the DART source via pyrolysis, and the products are then detected by high resolution MS. Temperature was shown to be a crucial parameter for the decomposition of large polysaccharide. The general behavior of carbohydrates in DART-MS was also studied through the investigation of a number of mono- and oligosaccharide standards. The chemical formula and putative ionic forms of the fragments were proposed based on accurate mass with less than 10 ppm mass errors. Multivariate data analysis shows the clear differentiation of different plant species. Intensities of marker ions compared among samples also showed obvious differences. The combination of DART-MS analysis and mechanochemical extraction method used in this work demonstrates a simple, fast, and high throughput analytical protocol for the efficient evaluation of molecular features in plant polysaccharides.

AB - The development of synthetic nanomaterials that could embed within, penetrate, or induce fusion between membranes without permanent disruption would have great significance for biomedical applications. Here we describe structure-function relationships of highly water-soluble gold nanoparticles comprised of an ~1.5-5 nm diameter metal core coated by an amphiphilic organic ligand shell, which exhibit membrane embedding and fusion activity mediated by the surface ligands. Using an environment-sensitive dye anchored within the ligand shell as a sensor of membrane embedding, we demonstrate that particles with core sizes of ~2-3 nm are capable of embedding within and penetrating fluid bilayers. At the nanoscale, these particles also promote spontaneous fusion of liposomes or spontaneously embed within intact liposomal vesicles. These studies provide nanoparticle design and selection principles that could be used in drug delivery applications, as membrane stains, or for the creation of novel organic/inorganic nanomaterial self assemblies.

AB - The success of Mycobacterium tuberculosis (Mtb) as a pathogen depends on the redundant and complex mechanisms it has evolved for resisting nitrosative and oxidative stresses inflicted by host immunity. Improving our understanding of these defense pathways can reveal vulnerable points in Mtb pathogenesis. In this study, we combined genetic, structural, computational, biochemical, and biophysical approaches to identify a novel enzyme class represented by Rv2466c. We show that Rv2466c is a mycothiol-dependent nitroreductase of Mtb and can reduce the nitro group of a novel mycobactericidal compound using mycothiol as a cofactor. In addition to its function as a nitroreductase, Rv2466c confers partial protection to menadione stress. PMID- 29465987 TI - Bimetallic Ag-Cu Supported on Graphitic Carbon Nitride Nanotubes for Improved Visible-Light Photocatalytic Hydrogen Production. AB - This work, for the first time, reports visible-light active bare graphitic carbon nitride nanotubes (C3N4 NTs) for photocatalytic hydrogen generation, even in the absence of any cocatalyst. Upon uniform dispersion of the cocatalysts, Ag-Cu nanoparticles, on the well-ordered bare C3N4 NTs, they exhibit twice the H2 evolution rate of the bare C3N4 NTs. The improved activity is attributed to their unique tubular nanostructure, strong metal-support interaction, and efficient photoinduced electron-hole separation compared to their bare and monometallic counterparts, evidenced by complementary characterization techniques. This work reveals that the H2 production rates correlate well with the oxidation potentials of the sacrificial reagents used. Triethylamine (TEA) outperforms other sacrificial reagents, including triethanolamine (TEOA) and methanol. Mechanistic studies on the role of various sacrificial reagents in photocatalytic H2 generation demonstrate that irreversible photodegradation of TEA into diethylamine and acetaldehyde via monoelectronic oxidation contributes to the improved H2 yield. Similarly, TEOA is oxidized to diethanolamine and glycolaldehyde, whereas methanol is unable to quickly capture the photoinduced holes and remains intact due to the low oxidation potential. PMID- 29465983 TI - Targeting the Proteostasis Network for Mycobacterial Drug Discovery. AB - Tuberculosis (TB), caused by Mycobacterium tuberculosis (Mtb), remains one of the world's deadliest infectious diseases and urgently requires new antibiotics to treat drug-resistant strains and to decrease the duration of therapy. During infection, Mtb encounters numerous stresses associated with host immunity, including hypoxia, reactive oxygen and nitrogen species, mild acidity, nutrient starvation, and metal sequestration and intoxication. The Mtb proteostasis network, composed of chaperones, proteases, and a eukaryotic-like proteasome, provides protection from stresses and chemistries of host immunity by maintaining the integrity of the mycobacterial proteome. In this Review, we explore the proteostasis network as a noncanonical target for antibacterial drug discovery.

AB - Optogenetics is an emerging technique that enables precise and specific control of biological activities in defined space and time. This technique employs naturally occurring or engineered light-responsive proteins to manipulate the physiological processes of the target cells. To better elucidate the molecular bases of neural functions, substantial efforts have been made to confer light sensitivity onto ion channels and neurotransmitter receptors that mediate signaling events within and between neurons. The chemical strategies for engineering light-switchable channels/receptors and the neuronal implementation of these tools are discussed.

AB - Photoactive yellow proteins (PYPs) make up a diverse class of blue-light absorbing bacterial photoreceptors. Electronic excitation of the p-coumaric acid chromophore covalently bound within PYP results in triphasic quenching kinetics; however, the molecular basis of this behavior remains unresolved. Here we explore this question by examining the excitation-wavelength dependence of the photodynamics of the PYP from Halorhodospira halophila via a combined experimental and computational approach. The fluorescence quantum yield, steady state fluorescence emission maximum, and cryotrapping spectra are demonstrated to depend on excitation wavelength. We also compare the femtosecond photodynamics in PYP at two excitation wavelengths (435 and 475 nm) with a dual-excitation wavelength-interleaved pump-probe technique. Multicompartment global analysis of these data demonstrates that the excited-state photochemistry of PYP depends subtly, but convincingly, on excitation wavelength with similar kinetics with distinctly different spectral features, including a shifted ground-state beach and altered stimulated emission oscillator strengths and peak positions. Three models involving multiple excited states, vibrationally enhanced barrier crossing, and inhomogeneity are proposed to interpret the observed excitation wavelength dependence of the data. Conformational heterogeneity was identified as the most probable model, which was supported with molecular mechanics simulations that identified two levels of inhomogeneity involving the orientation of the R52 residue and different hydrogen bonding networks with the p-coumaric acid chromophore. Quantum calculations were used to confirm that these inhomogeneities track to altered spectral properties consistent with the experimental results. PMID- 29465992 TI - Local Structure of Zr(OH)4 and the Effect of Calcination Temperature from X-ray Pair Distribution Function Analysis. AB - Analysis of X-ray pair distribution function data has provided a detailed picture of the local structure of amorphous Zr(OH)4 and its thermal decomposition into ZrO2. In the untreated phase, the Zr atoms tend to be coordinated by six or seven oxygen atoms. The Zr centered polyhedra connect to each other primarily by sharing edges, but also with a significant amount of corner sharing, to form two dimensional sheets in which the Zr are connected to an average of about five other Zr. This local structure is related to the structure of monoclinic ZrO2 and can be derived from it by removing certain Zr neighbors to form sheets and reduce the corner to edge sharing ratio. The maximum correlation length in Zr(OH)4 is about 12 A. Heating up to 125 degrees C results in significant water loss but does not alter the network of Zr and bridging O atoms. Additional water loss caused by heating to 250 degrees C triggers a reorganization into a new type of amorphous phase with a three-dimensional network and a greater number of Zr-Zr neighbors. Further heating to 330 degrees C causes crystallization into a mixture of tetragonal and monoclinic ZrO2, with the minor tetragonal phase having a smaller average domain size. The tetragonal component vanishes by 900 degrees C.

AB - By utilizing a preselected functional ligand produced by 1 H-imidazole-4,5 dicarboxylic acid, three isostructural lanthanide coordination polymers (CPs), denoted as {[Ln2(OH)2(L)2].(DMF).(H2O)4} n (Ln = Gd (1), Eu (2), Dy (3); L = 1-(4 carboxybenzyl)imidazole-4-carboxylic acid), containing a 1D infinite [Ln4(OH)4] subchain have been successfully constructed. The highly connected mode between the multifunctional ligand and 1D building units is responsible for the exceptional chemical stability of three lanthanide CPs. In addition, a study of the magnetic properties reveals that 1 displays a large magnetic entropy change ( Delta Sm = 30.33 J kg-1 K-1 with T = 2 K and Delta H = 7 T). Furthermore, genetic algorithm and quantum Monte Carlo methods were combined to simulate the magnetic coupling parameters of compound 1, shedding light on the effect of linking bridges on magnetic propagation. 2 shows intense luminescence in the range of 350 710 nm. Comparably, magnetic studies of 3 reveal the existence of a metamagnetic transformation from an antiferromagnetic interaction to a ferromagnetic interaction along with a decrease in temperature. Through fitting of the results of HF-EPR measurements, a component of the g tensor is obtained, g|| = 16.4(5), indicating the large anisotropy of 3.

AB - The structures and properties of vanadium oxides are often related to the formation of molecule-like clusters of vanadium cations through direct V-V bonding. GaV2O4, a new vanadium spinel, was synthesized. Powder diffraction and X ray total scattering studies, complemented by magnetization and resistivity measurements, reveal that the low-temperature phase of this material is structurally distorted and features ordered pairs of three- and four-atom vanadium clusters. These clusters persist into a disordered cubic phase above the charge-ordering transition at TCO = 415 K. Furthermore, quasi-elastic neutron scattering indicates that the disordered clusters remain well-defined and static to 1100 K. PMID- 29465995 TI - Natural Porphyrins Accelerating the Phototransformation of Benzo[a]pyrene in Water. AB - Phototransformation is one of the most important transformation pathways of organic contaminants in the water environment. However, how active compounds enable and accelerate the phototransformation of organic pollutants remains to be elucidated. In this study, the phototransformation of benzo[a]pyrene (BaP, the first class "human carcinogens") by various natural porphyrins under solar irradiation was investigated, including chlorophyll a, sodium copper chlorophyllin, hematin, cobalamin, and pheophorbide a. Transformation efficiency of BaP varied considerably with chemical stabilities of the porphyrins. Porphyrins with a lower stability displayed higher BaP transformation efficiencies. BaP transformation had a significant positive correlation with the production of singlet oxygen. Identical phototransformation products of BaP were observed for all investigated porphyrins, and the main products were identified as BaP-quinones, including BaP-1,6-dione, BaP-3,6-dione, and BaP-6,12-dione. The mechanism of natural porphyrins accelerating the BaP phototransformation in water was proposed to proceed via the photocatalytic generation of singlet oxygen resulting in the transformation of BaP to quinones. PMID- 29465996 TI - Palladium and Lewis-Acid-Catalyzed Intramolecular Aminocyanation of Alkenes: Scope, Mechanism, and Stereoselective Alkene Difunctionalizations. AB - An expansion of methodologies aimed at the formation of versatile organonitriles, via the intramolecular aminocyanation of unactivated alkenes, is herein reported. Importantly, the need for a rigid tether in these reactions has been obviated. The ease-of-synthesis and viability of substrates bearing flexible backbones has permitted for diastereoselective variants as well. We demonstrated the utility of this methodology with the formation of pyrrolidones, piperidinones, isoindolinones, and sultams. Furthermore, subsequent transformation of these motifs into medicinally relevant molecules is also demonstrated. A double crossover 13C-labeling experiment is consistent with a fully intramolecular cyclization mechanism. Deuterium labeling experiments support a mechanism involving syn-addition across the alkene.

AB - The enhancement of two-stage anaerobic digestion of polysaccharide-enriched food waste by the addition of cysteine-an oxygen scavenger, electron mediator, and nitrogen source-to the acidification stage was reported. It was found that in the acidification stage the accumulation of volatile fatty acids (VFA), which mainly consisted of acetate, butyrate, and propionate, was increased by 49.3% at a cysteine dosage of 50 mg/L. Although some cysteine was biodegraded in the acidification stage, the VFA derived from cysteine was negligible. In the methanogenesis stage, the biotransformations of both VFA and biohydrogen to methane were enhanced, and the methane yield was improved by 43.9%. The mechanisms study showed that both d-glucose and l-glucose (the model monosaccharides) were detectable in the hydrolysis product, and the addition of cysteine remarkably increased the acidification of l-glucose, especially acetic acid and hydrogen generation, due to key enzymes involved in l-glucose metabolism being enhanced. Cysteine also improved the activity of homoacetogens by 34.8% and hydrogenotrophic methanogens by 54%, which might be due to the electron transfer process being accelerated. This study provided an alternative method to improve anaerobic digestion performance and energy recovery from food waste.

PMID- 29465999 TI - Efficient Method for Calculating Effective Core Potential Integrals. AB - Effective core potential (ECP) integrals are among the most difficult one electron integrals to calculate due to the projection operators. The radial part of these operators may include r0, r-1, and r-2 terms. For the r0 terms, we exploit a simple analytic expression for the fundamental projected integral to derive new recurrence relations and upper bounds for ECP integrals. For the r-1 and r-2 terms, we present a reconstruction method that replaces these terms by a sum of r0 terms and show that the resulting errors are chemically insignificant for a range of molecular properties. The new algorithm is available in Q-Chem 5.0 and is significantly faster than the ECP implementations in Q-Chem 4.4, GAMESS (US) and Dalton 2016.

AB - Multidrug-resistant Staphylococcus aureus, including MRSA (methicillin-resistant) and VRSA (vancomycin-resistant), causes serious healthcare-associated infections, even sepsis and death. Here, we identified six novel cathelicidins (CATHPb1-6) from Python bivittatu, and CATHPb1 displayed the best in vitro pharmacological and toxicological profile. We further show that CATHPb1 exhibited evident protection in mice MRSA/VRSA infection models, given either 24 h before or 4 h after infection. The protection was all effective through different administration routes, but was blocked by in vivo depletion of monocyte/macrophages or neutrophils. CATHPb1 can rapidly and massively modulate macrophages/monocytes and neutrophils trafficking to the infection site, and potentiate their bactericidal functions. Meanwhile, CATHPb1 remarkably augmented neutrophil-mediated bacteria killing by facilitating neutrophil extracellular traps (NETs) formation and preventing its degradation. Acting through MAPKs and NF-kappaB pathways, CATHPb1 selectively enhanced the levels of chemokines while reducing the production of pro-inflammatory cytokines without undesirable toxicities. The much improved serum half-life and stabilities confer CATHPb1 an excellent prospect to become a novel therapeutic agent against multidrug resistant staphylococcal infections. PMID- 29466001 TI - Introduction of Intrinsic Kinetics of Protein-Ligand Interactions and Their Implications for Drug Design. AB - Structure-kinetic relationship analyses and identification of dominating interactions for optimization of lead compounds should ideally be based on intrinsic rate constants instead of the more easily accessible observed kinetic constants, which also account for binding-linked reactions. The intrinsic rate constants for sulfonamide inhibitors and pharmacologically relevant isoforms of carbonic anhydrase were determined by a novel surface plasmon resonance (SPR) biosensor-based approach, using chemodynamic analysis of binding-linked pH dependent effects. The observed association rates ( kaobs) were pH-dependent and correlated with the fraction of deprotonated inhibitor and protonated zinc-bound water molecule. The intrinsic association rate constants ( kaintr) were pH independent and higher than kaobs. By contrast, the observed and intrinsic dissociation rate constants were identical and pH-independent, demonstrating that the observed association and dissociation mechanisms are inherently different. A model accounting for the differences between intrinsic and observed rate constants was developed, useful also for other interactions with binding-linked protonation reactions.

To drive development toward specific oncopathways, compounds were tested against cancer cells that overexpress, or not, AXL kinase.

PMID- 29466003 TI - Electronic Structure and Bonding Situation in M2O2 (M = Be, Mg, Ca) Rhombic Clusters. AB - Quantum chemical calculations using ab initio methods at the CCSD(T) level and density functional theory have been carried out for the title molecules. The electronic structures of the molecules were analyzed with a variety of charge and energy decomposition methods. The equilibrium geometries of the M2O2 rhombic clusters exhibit very short distances between the transannular metal atoms M = Be, Mg, Ca. The calculated distances are close to standard values between double and triple bonds, but there are no chemical M-M bonds. The metal atoms M carry large positive partial charges, which are even bigger than in diatomic MO. The valence electrons of M are essentially shifted toward oxygen in M2O2, which makes it possible that there is practically no electronic charge in the region between the metal atoms. The bond dissociation energies for fragmentation of M2O2 into two metal oxides MO are very large. The metal-oxide bonds in the rhombic clusters are shorter and stronger than in diatomic MO. A detailed analysis of the electronic structure suggests that there is no significant direct M-M interaction in the M2O2 rhombic clusters, albeit weak three-center M-O-M bonding. PMID- 29466004 TI - Reaction Coordinate, Free Energy, and Rate of Intramolecular Proton Transfer in Human Carbonic Anhydrase II. AB - The role of structure and dynamics of an enzyme has been investigated at three different stages of its function including the chemical event it catalyzes. A one pot computational method has been designed for each of these stages on the basis of classical and/or quantum mechanical-molecular mechanical molecular dynamics and transition path sampling simulations. For a pair of initial and final states A and B separated by a high free-energy barrier, using a two-stage selection process, several collective variables (CVs) are identified that can delineate A and B. However, these CVs are found to exhibit strong cross-coupling over the transition paths. A set of mutually orthogonal order parameters is then derived from these CVs and an optimal reaction coordinate, r, determined applying half trajectory likelihood maximization along with a Bayesian information criterion. The transition paths are also used to project the multidimensional free energy surface and barrier crossing dynamics along r. The proposed scheme has been applied to the rate-determining intramolecular proton transfer reaction of the well-known enzyme human carbonic anhydrase II. The potential of mean force, F( r), in the absence of the chemical step is found to reproduce earlier results on the equilibrium population of two side-chain orientations of key residue His-64. Estimation of rate constants, k, from mean first passage times for the three different stages of catalysis shows that the rate-determining step of intramolecular proton transfer occurs with k ? 1.0 * 106 s-1, in close agreement with known experimental results. PMID- 29466006 TI - Quantum Stochastic Trajectories: The Fokker-Planck-Bohm Equation Driven by the Reduced Density Matrix. AB - The quantum molecular trajectory is the deterministic trajectory, arising from the Bohm theory, that describes the instantaneous positions of the nuclei of molecules by assuring the agreement with the predictions of quantum mechanics. Therefore, it provides the suitable framework for representing the geometry and the motions of molecules without neglecting their quantum nature. However, the quantum molecular trajectory is extremely demanding from the computational point of view, and this strongly limits its applications. To overcome such a drawback, we derive a stochastic representation of the quantum molecular trajectory, through projection operator techniques, for the degrees of freedom of an open quantum system. The resulting Fokker-Planck operator is parametrically dependent upon the reduced density matrix of the open system. Because of the pilot role played by the reduced density matrix, this stochastic approach is able to represent accurately the main features of the open system motions both at equilibrium and out of equilibrium with the environment. To verify this procedure, the predictions of the stochastic and deterministic representation are compared for a model system of six interacting harmonic oscillators, where one oscillator is taken as the open quantum system of interest. The undeniable advantage of the stochastic approach is that of providing a simplified and self contained representation of the dynamics of the open system coordinates. Furthermore, it can be employed to study the out of equilibrium dynamics and the relaxation of quantum molecular motions during photoinduced processes, like photoinduced conformational changes and proton transfers. PMID- 29466005 TI - Optimization of Metabolic and Renal Clearance in a Series of Indole Acid Direct Activators of 5'-Adenosine Monophosphate-Activated Protein Kinase (AMPK). AB - Optimization of the pharmacokinetic (PK) properties of a series of activators of adenosine monophosphate-activated protein kinase (AMPK) is described. Derivatives of the previously described 5-aryl-indole-3-carboxylic acid clinical candidate (1) were examined with the goal of reducing glucuronidation rate and minimizing renal excretion. Compounds 10 (PF-06679142) and 14 (PF-06685249) exhibited robust activation of AMPK in rat kidneys as well as desirable oral absorption, low plasma clearance, and negligible renal clearance in preclinical species. A correlation of in vivo renal clearance in rats with in vitro uptake by human and rat renal organic anion transporters (human OAT/rat Oat) was identified. Variation of polar functional groups was critical to mitigate active renal clearance mediated by the Oat3 transporter. Modification of either the 6 chloroindole core to a 4,6-difluoroindole or the 5-phenyl substituent to a substituted 5-(3-pyridyl) group provided improved metabolic stability while minimizing propensity for active transport by OAT3. PMID- 29466007 TI - Steric Crowding in Tetrel Bonds. AB - The tetravalent character of tetrel atoms leaves only limited room for an incoming nucleophile to approach and engage in a noncovalent bond with a tetrel atom. Any such approach can only occur at the expense of internal geometric distortions. The balance between attractive forces and repulsive steric crowding was studied for a series of Lewis acids of the type FTR3 (T = Si, Ge, Sn, Pb) which were allowed to interact with various bases. The strength and other properties of the tetrel bond are examined as the R groups are made progressively larger, varying from H and CH3 to isopropyl and tert-butyl, which induce steric crowding with the incoming base. The effects of crowding which impede the bond can be offset by enlarging the T atom, by adding electron-withdrawing substituents to the Lewis acid, or by considering stronger bases such as anions. The tetrel bond energies reach up to 10 kcal/mol for a pair of neutral molecules with no electron-withdrawing substituents on the Lewis acid. Adding -CF3 substituents grows the interaction energy to as high as 35 kcal/mol, and a further increment occurs for an anionic base, taking the maximum up to 54 kcal/mol. PMID- 29466008 TI - Raman Microscopy Insights on the Out-of-Plane Electrical Transport of Carbon Nanotube-Doped PEDOT:PSS Electrodes for Solar Cell Applications. AB - In the present report, we focused on the study of the out-of-plane electrical transport of multiwalled carbon nanotube (MWCNT)-doped poly(3,4 ethylenedioxythiophene):poly(styrene sulfonate) composites (PEDOT:PSS-MWCNTs) as electrodes for solar cell applications. The out-of-plane direct current and alternating current electrical transport, rarely studied but not less relevant, was additionally supported with in-plane and out-of-plane confocal Raman microscopy and grazing incidence small-angle X-ray scattering characterizations. The main relevance of our study is the monitoring of the polymer structure all across the polymeric film by using confocal Raman spectroscopy and its correlation with electrical transport. Modifications in the PEDOT benzenoid and quinoid conformations were observed in the vicinities of MWCNTs, and the enrichment of PSS at the indium tin oxide electrode interface was also evidenced. In consequence, the low MWCNT loadings into PEDOT:PSS lead to an increase of the out-of-plane conductivity, but the heavier MWCNT loadings lead to a drastic decrease. The tuning of the doping level of these polymer composites and the understanding of the interface structure are crucial to fabricate electrodes with higher out-of-plane conductivities for organic solar cell applications.

In ultrafast vibrational spectroscopy, changes in the vibrational features of hydrogen-bonded NH and OH stretch modes are typically observed to persist long after these high frequency vibrations have relaxed. Due to the resemblance to the spectral changes caused by heating the sample, these features are typically described as arising from a hot ground state. However, these spectral features appear on ultrafast time scales that are much too fast to result from a true thermal state, and significant differences between the thermal difference spectrum and the induced quasi-thermal changes in ultrafast spectroscopy are often observed. Here, we examine and directly compare the thermal and quasi-thermal responses of the hydrogen-bonded homodimer of 7-azaindole with temperature-dependent FTIR spectroscopy and ultrafast mid-IR continuum spectroscopy. We find that the thermal difference spectra contain contributions from both dissociation of the hydrogen bonds and from frequency shifts due to changes in the thermal population of low-frequency modes. The transient spectra in ultrafast vibrational spectroscopy are also found to contain two contributions: initial frequency shifts over 2.3 +/- 0.11 ps associated with equilibration of the initial excitation, and frequency shifts associated with the excitation of several fingerprint modes, which decay over 21.8 +/- 0.11 ps, giving rise to a quasi thermal response caused by a distribution of fingerprint modes being excited within the sample ensemble. This resembles the thermal frequency shifts due to population changes of low-frequency modes, but not the overall thermal spectrum, which is dominated by features caused by dimer dissociation. These findings provide insight into the changes in the vibrational spectrum from different origins and are important for assigning, analyzing, and comparing features in thermal and ultrafast vibrational spectroscopy of hydrogen-bonded complexes. PMID- 29466010 TI - Dielectric Properties of a Protein Probed by Reversal of a Buried Ion Pair. AB - Thirty years ago, Hwang and Warshel suggested that a microenvironment preorganized to stabilize an ion pair would be incapable of reorganizing to stabilize the reverse ion pair. The implications were that (1) proteins have a limited capacity to reorganize, even under the influence of strong interactions, such as those present when ionizable groups are buried in the hydrophobic interior of a protein, and (2) the inability of proteins to tolerate the reversal of buried ion pairs demonstrates the limitations inherent to continuum electrostatic models of proteins. Previously we showed that when buried individually in the interior of staphylococcal nuclease, Glu23 and Lys36 have p Ka values near pH 7, but when buried simultaneously, they establish a strong interaction of ~5 kcal/mol and have p Ka values shifted toward more normal values. Here, using equilibrium thermodynamic measurements, crystal structures, and NMR spectroscopy experiments, we show that although the reversed, individual substitutions-Lys23 and Glu36-also have p Ka values near 7, when buried together, they neither establish a strong interaction nor promote reorganization of their microenvironment. These experiments both confirm Warshel's original hypothesis and expand it by showing that it applies to reorganization, as demonstrated by our artificial ion pairs, as well as to preorganization as is commonly argued for motifs that stabilize naturally occurring ion pairs in polar microenvironments. These data constitute a challenging benchmark useful to test the ability of structure-based algorithms to reproduce the compensation between self-energy, Coulomb and polar interactions in hydrophobic environments of proteins.

A variety of diaryl and aryl alkyl N-H imines participated in the reaction to afford the corresponding branched adducts in good yield and regioselectivity. Interestingly, unsymmetrical diaryl imines with modest electronic biases reacted regioselectively at one of the aryl rings. Furthermore, the branched selectivity was reversed for substrates bearing a secondary directing group or a bulky pivaloyl N-H imine. PMID- 29466012 TI - Primary and Higher Order Structure of the Reaction Center from the Purple Phototrophic Bacterium Blastochloris viridis: A Test for Native Mass Spectrometry. AB - The reaction center (RC) from the phototrophic bacterium Blastochloris viridis was the first integral membrane protein complex to have its structure determined by X-ray crystallography and has been studied extensively since then. It is composed of four protein subunits, H, M, L, and C, as well as cofactors, including bacteriopheophytin (BPh), bacteriochlorophyll (BCh), menaquinone, ubiquinone, heme, carotenoid, and Fe. In this study, we utilized mass spectrometry-based proteomics to study this protein complex via bottom-up sequencing, intact protein mass analysis, and native MS ligand-binding analysis. Its primary structure shows a series of mutations, including an unusual alteration and extension on the C-terminus of the M-subunit. In terms of quaternary structure, proteins such as this containing many cofactors serve to test the ability to introduce native-state protein assemblies into the gas phase because the cofactors will not be retained if the quaternary structure is seriously perturbed. Furthermore, this specific RC, under native MS, exhibits a strong ability not only to bind the special pair but also to preserve the two peripheral BCh's. PMID- 29466013 TI - Evidence of a Transition Layer between the Free Surface and the Bulk. AB - The free surface, a very thin layer at the interface between polymer and air, is considered the main source of the perturbations in the properties of ultrathin polymer films, i.e., nanoconfinement effects. The structural relaxation of such a layer is decoupled from the molecular dynamics of the bulk. The free surface is, in fact, able to stay liquid even below the temperature where the polymer resides in the glassy state. Importantly, this surface layer is expected to have a very sharp interface with the underlying bulk. Here, by analyzing the penetration of n hexane into polystyrene films, we report on the existence of a transition region, not observed by previous investigations, extending for 12 nm below the free surface. The presence of such a layer permits reconciling the behavior of interfacial layers with current models and has profound implications on the performance of ultrathin membranes. We show that the expected increase in the flux of the permeating species is actually overruled by nanoconfinement. PMID- 29466014 TI - Impact of Polyelectrolyte Multilayers on the Ionic Current Rectification of Conical Nanopores. AB - Single conical nanopores were functionalised layer by layer with weak polyelectrolytes. We studied their influence on the ionic diode properties We have considered different couples of polyelectrolytes: poly-l-lysine/poly(acrylic acid) and poly(ethyleneimine)/poly(acrylic acid) as well as the influence of cross-linking. The results show that the nanopores decorated with poly(ethyleneimine)/poly(acrylic acid) exhibit an interesting behavior. Indeed, at pH 3, the nanopore is open only at the low salt concentration, while at pH 7, it is already open. The nanopores functionalized with poly-l-lysine/poly(acrylic acid) do not show an inversion of ionic transport properties with the pH as expected. After cross-linked to prevent large conformational changes, the ionic diode properties are dependent on the pH.

AB - In many insects, mating induces drastic changes in male and female responses to sex pheromones or host-plant odors. In the male moth Agrotis ipsilon, mating induces a transient inhibition of behavioral and neuronal responses to the female sex pheromone. As neuropeptides and peptide hormones regulate most behavioral processes, we hypothesize that they could be involved in this mating-dependent olfactory plasticity. Here we used next-generation RNA sequencing and a combination of liquid chromatography, matrix assisted laser desorption ionization time-of-flight (MALDI-TOF) mass spectrometry, and direct tissue profiling to analyze the transcriptome and peptidome of different brain compartments in virgin and mated males and females of A. ipsilon. We identified 37 transcripts encoding putative neuropeptide precursors and 54 putative bioactive neuropeptides from 23 neuropeptide precursors (70 sequences in total, 25 neuropeptide precursors) in different areas of the central nervous system including the antennal lobes, the gnathal ganglion, and the corpora cardiaca-corpora allata complex. Comparisons between virgin and mated males and females revealed tissue-specific differences in peptide composition between sexes and according to physiological state. Mated males showed postmating differences in neuropeptide occurrence, which could participate in the mating-induced olfactory plasticity.

AB - The C-H heteroarylation of benzaldehydes with indoles and pyrroles was realized using the benziodoxolone hypervalent iodine reagents indole- and pyrroleBX. Functionalization of the aldehyde C-H bond using either an o-hydroxy or amino directing group and catalyzed by an iridium or a rhodium complex allowed the synthesis of salicyloylindoles and (2-sulfonamino)benzoylindoles, respectively, with good to excellent yields (74-98%). This new transformation could be carried out under mild conditions (rt to 40 degrees C) and tolerated a broad range of functionalities, such as ethers, halogens, carbonyls, or nitro groups.

AB - Direct oxidative deamination of glyoxal-derived Ugi-azide and Ugi three-component reaction products readily affords vicinal tricarbonyls (alpha,beta-diketoamides) and alpha,beta-diketotetrazoles with two diversity elements. This significant extension of our previously described multicomponent reaction-oxidative deamination methodology is proposed to proceed through a mechanistically distinct SeO2-mediated C-N oxidation derived from an active enol of alpha-amino-beta ketone systems, effectively an aza-Riley oxidation. This methodology accesses diverse VTC systems from prototypical amines, glyoxaldehydes, and isocyanide building blocks in a mere two steps. PMID- 29466018 TI - Differences in learning retention when teaching a manual motor skill with a visual vs written instructional aide. AB - OBJECTIVE:: This study aimed to determine if a written or visual teaching aid influenced learning retention when teaching a manual motor skill. METHODS:: Seventy chiropractic students who had completed an upper cervical specific chiropractic technique course were evaluated for technique-specific recall before and after a review using either a visual teaching aid or a written guide. Two randomized groups reviewed original course-written guides ( n = 33) or new visual teaching aids ( n = 37). Repeated-measures analysis of variance and post hoc t tests compared group differences in reevaluation scores. RESULTS:: Performance of both groups improved postintervention ( F[1, 68] = 182.56, p < .001). However, the visual teaching aid group improved more than the written guide group ( F[1, 68] = 4.66, p = .03). The visual teaching aid group percentage score improved by 24.4% (SD +/- 12.3%, p < .01); the written guide group improved by 17.7% (SD +/- 13.7%; p < .01). CONCLUSION:: The mean learning retention improved in both the visual and the written teaching guide groups, but there was greater improvement in the visual aid group. This study suggests that visual teaching aids may be more useful than written guides when students attempt to recall information related to learning a manual motor skill. PMID- 29466019 TI - Video Analysis of Anterior Cruciate Ligament Tears in Professional American Football Athletes. AB - BACKGROUND: Anterior cruciate ligament (ACL) injuries are prevalent in contact sports that feature cutting and pivoting, such as American football. These injuries typically require surgical treatment, can result in significant missed time from competition, and may have deleterious long-term effects on an athlete's playing career and health. While the majority of ACL tears in other sports have been shown to occur from a noncontact mechanism, it stands to reason that a significant number of ACL tears in American football would occur after contact, given the nature of the sport. Hypothesis/Purpose: The purpose was to describe the mechanism, playing situation, and lower extremity limb position associated with ACL injuries in professional American football players through video analysis to test the hypothesis that a majority of injuries occur via a contact mechanism. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: A retrospective cohort of National Football League (NFL) players with ACL injuries from 3 consecutive seasons (2013-2016) was populated by searching publicly available online databases and other traditional media sources. Of 156 ACL injuries identified, 77 occurred during the regular season and playoffs, with video analysis available for 69 injuries. The video of each injury was independently viewed by 2 reviewers to determine the nature of the injury (ie, whether it occurred via a noncontact mechanism), the position of the lower extremity, and the football activity at the time of injury. Playing surface, player position, and time that the injury occurred were also recorded. RESULTS: Contrary to our hypothesis, the majority of ACL injuries occurred via a noncontact mechanism (50 of 69, 72.5%), with the exception of injury to offensive linemen, who had a noncontact mechanism in only 20% of injuries. For noncontact injuries, the most common football activity at the time of injury was pivoting/cutting, and the most common position of the injured extremity included hip abduction/flexion, early knee flexion/abduction, and foot abduction/external rotation. There was no association between injury mechanism and time of injury or playing surface in this cohort. CONCLUSION: In this study of players in the NFL, the majority of ACL tears involved a noncontact mechanism, with the lower extremity exhibiting a dynamic valgus moment at the knee. These findings suggest that ACL injury prevention programs may reduce the risk of noncontact ACL tears in American football players. PMID- 29466021 TI - Assessment of Performance Carryover Effects Due to Successive Exposure to Different Lateral Camera Rotations in a Laparoscopic Training Environment. AB - Objective The aim of this study was to assess performance carryover effects associated with different successive lateral camera rotations in the laparoscopic training environment. Background Laparoscopy requires surgeons to adapt to disruptions of visuomotor mapping. A gradual adaptation process is hypothesized to be effective up to a given rotation threshold; this threshold may have performance implications for successive exposure to different lateral camera rotations. Method Two experiments utilized a laparoscopic training task. Experiment 1 exposed novices to a subsequent rotation that was either 45 degrees larger than one of the initial rotations of 45 degrees , 75 degrees , 105 degrees , and 135 degrees or 45 degrees smaller than one of the initial rotations of 90 degrees , 120 degrees , 150 degrees , and 180 degrees . Experiment 2 exposed novices to either stepwise increasing rotations (0 degrees to 180 degrees ) or stepwise decreasing rotations (180 degrees to 0 degrees ). Results Regarding Experiment 1, performance generally improved for subsequent rotations that were 45 degrees larger than the initial rotation, except for one condition (initial rotation, 105 degrees ; subsequent rotation, 150 degrees ). Performance generally improved for subsequent rotations that were 45 degrees smaller than the initial rotation, except for one condition (initial rotation, 120 degrees ; subsequent rotation, 75 degrees ). Experiment 2 indicated worst performance at 120 degrees for the increasing and decreasing conditions. This finding suggests an identical threshold for increasing and decreasing rotations, which is inconsistent with Experiment 1 results. Conclusion Improved performance due to carryover effects from successive exposure to lateral camera rotations in the laparoscopic training environment is contingent on the specific camera rotations. Application Supplementary laparoscopic training might be needed for surgeries that entail certain successive lateral camera rotations.

PMID- 29466024 TI - Sexual Self-Efficacy and Gender: A Review of Condom Use and Sexual Negotiation Among Young Men and Women in Sub-Saharan Africa. AB - Sexual self-efficacy (SSE), one's perceived control of or confidence in the ability to perform a given sexual outcome, predicts sexual behavior; however, important questions remain regarding whether gender modifies observed associations. In a comprehensive review of peer-reviewed HIV-prevention literature focusing on youth (ages 10 to 25) in sub-Saharan Africa, we measured and assessed the influence of SSE on condom use and sexual refusal, overall and by gender. Our results, after reviewing 63 publications, show that SSE is inconsistently measured. Most studies measured condom use self-efficacy (CUSE) (96.8%) and/or sexual refusal self-efficacy (SRSE) (63.5%). On average, young men had higher CUSE than young women, while young women had higher SRSE than young men. While cross-sectional studies reported an association between high SSE and sexual behaviors, this association was not observed in interventions, particularly among young women who face a disproportionate risk of HIV acquisition. In all, 25% of intervention studies demonstrated that fostering CUSE increased condom use among young men only, and one of two studies demonstrated that higher SRSE led to reduced frequency of sexual activity for both men and women. Future research and HIV-prevention interventions must be gender targeted, consider improving CUSE for young men, and move beyond limited individual-level sexual behavior change frameworks. PMID- 29466026 TI - Opposition-Based Memetic Algorithm and Hybrid Approach for Sorting Permutations by Reversals. AB - Sorting unsigned permutations by reversals is a difficult problem; indeed, it was proved to be NP-hard by Caprara (1997). Because of its high complexity, many approximation algorithms to compute the minimal reversal distance were proposed until reaching the nowadays best-known theoretical ratio of 1.375. In this article, two memetic algorithms to compute the reversal distance are proposed. The first one uses the technique of opposition-based learning leading to an opposition-based memetic algorithm; the second one improves the previous algorithm by applying the heuristic of two breakpoint elimination leading to a hybrid approach. Several experiments were performed with one-hundred randomly generated permutations, single benchmark permutations, and biological permutations. Results of the experiments showed that the proposed OBMA and Hybrid OBMA algorithms achieve the best results for practical cases, that is, for permutations of length up to 120. Also, Hybrid-OBMA showed to improve the results of OBMA for permutations greater than or equal to 60. The applicability of our proposed algorithms was checked processing permutations based on biological data, in which case OBMA gave the best average results for all instances. PMID- 29466027 TI - Effect of Cold-Water Immersion on Handgrip Performance in Rock Climbers. AB - PURPOSE: To determine the effect of 2 cold-water-immersion (CWI) temperatures (15 degrees C and 8 degrees C) on repeat handgrip performance to failure. METHODS: A total of 32 participants completed 3 intermittent trials to failure on a climbing specific handgrip dynamometer on 3 laboratory visits. For each visit, a different recovery strategy was employed: passive (PAS) recovery, CWI at 8 degrees C (CW8), or CWI at 15 degrees C (CW15). The force time integral (FTI: time of contraction multiplied by the force of contraction) was determined to assess handgrip performance. RESULTS: There was no significant difference between recovery strategies at the end of trial 1. In response to the PAS recovery strategy, there were 10% and 22% decreases in FTI in the second and third trials, respectively. The PAS recovery-strategy FTI values were lower than both CWI strategies for trials 2 and 3 (P < .05). FTI increased in the second trial (?32% and ?38%; P < .05) for both immersion strategies (CW8 and CW15, respectively) compared with trial 1. During the third trial, FTI was significantly higher for CW15 than CW8 (?27% and ?4% with respect to baseline trial; P < .05). CONCLUSIONS: The results suggest that CWI has potential performance advantages over PAS recovery for rock climbing. The data show that in events where multiple recoveries are required, 15 degrees C CWI may be more beneficial for climbers than 8 degrees C CWI. Future research should focus on the optimization of protocols for sport performance. PMID- 29466033 TI - A New Era of Cancer Biotherapy and Radiopharmaceuticals. PMID- 29466028 TI - Analysis of the Impact of Common Polymorphisms of the FTO and MC4R Genes with the Risk of Severe Obesity in Saudi Arabian Population. AB - BACKGROUND: Obesity has reached epidemic proportions worldwide resulting in a serious public health problem. In Saudi Arabia, 28.7% of the population is obese due largely to the adoption of western dietary patterns over the last decade. The fat-mass and obesity associated (FTO) and melanocortin-4 receptor (MC4R) genes are ubiquitously expressed in the brain and pancreatic islets, and are the main link between the central nervous system and energy homeostasis based on food intake and energy expenditure. Genetic variants in the FTO and MC4R genes have been strongly associated with an increased obesity risk. AIM: To identify novel mutations in the MC4R gene and to perform correlation analyses of the known variants rs9939609 and rs1421085 in the FTO gene and rs17782313 near the MC4R gene in an obese Saudi population. MATERIALS AND METHODS: A total of 136 obese patients and 104 healthy controls from King Fahd Hospital, Al-Khobar, were genotyped for single-nucleotide polymorphisms within or near the FTO and MC4R genes using the TaqMan assay. Leptin levels were determined by enzyme-linked immunosorbent assay. Targeted sequencing of MC4R exon was done by Sanger sequencing method. RESULTS: The study included 58 obese males and 78 obese females with a mean age of 39.78 +/- 12.77 years and a mean body mass index (BMI) of 42.65 +/- 9.03 kg/m2. A significant increase in the levels of leptin and triglycerides was associated with an increase of BMI. Other factors such as lactate dehydrogenase, gamma-glutamyltransferase, and high-density lipoprotein were also significantly higher in the severely obese cohort. The FTO polymorphisms were associated with a significantly increased risk for obesity and in BMI-stratified cohort, rs9939609 (T/A: odds ratio [OR] = 1.73, p = 0.007) and rs1421085 (T/C: OR = 1.56, p = 0.03) showed even stronger association. Genotyping for the near MC4R polymorphism, rs17782313 revealed an association with moderately obese patients (T/C: OR = 1.73, p = 0.038). CONCLUSION: The studied FTO gene polymorphisms were found to be significantly associated with increased BMI and were highly significantly associated with severe obesity. These FTO gene polymorphisms combined with a high-fat diet appear to promote early-onset obesity in the Saudi population. FTO polymorphisms appear to be universally associated with the risk of obesity, and further investigation into this genetic locus may provide clues for potential therapeutic targets. PMID- 29466034 TI - Astragalus Saponins and Liposome Constitute an Efficacious Adjuvant Formulation for Cancer Vaccines. AB - Cancer vaccines mostly aim to induce cytotoxic T lymphocytes (CTLs) against tumors. An appropriate adjuvant is of fundamental importance for inducing cellular immune response. Since the antigen in particulate form is substantially more immunogenic than soluble form antigen, it is beneficial to interact with antigen-presenting cells membrane to induce robust CD8+ T cell activation following vaccination. Based on previous research, we designed an adjuvant formulation by combining Astragalus saponins, cholesterol, and liposome to incorporate antigen into a particulate delivery system, so as to enhance cellular immune response. Meanwhile, angiogenesis contributes to tumor growth and metastasis, and basic fibroblast growth factor (bFGF) is involved in tumor angiogenesis. Therefore, using lipo-saponins adjuvant formulation and a human recombinant bFGF antigen protein, we tried to induce bFGF-specific CTL response to inhibit tumor angiogenesis to achieve antitumor activity. After five immunizations, the lipo-saponins/bFGF complex elicited robust antibody response and markedly higher amount of interferon-gamma in BALB/c mice, resulting in superior antitumor activities. Decreased microvessel density in CD31 immunohistochemistry and the lysis of vascular endothelial cells by the T lymphocytes from the immunized mice indicated that the immunity inhibited the angiogenesis of tumors and further led to the inhibition of tumors. Our data suggest that the approach to construct adjuvant formulation between liposome and Astragalus saponins appeared highly desirable, and that Astragalus saponins may be utilized as a valuable additive for enhancing the effectiveness of vaccines and stimulating an appropriate immune response that can benefit tumor therapy. PMID- 29466035 TI - Inhibition of STAT6/Anoctamin-1 Activation Suppresses Proliferation and Invasion of Gastric Cancer Cells. AB - BACKGROUND: Gastric carcinoma is the most popular cancer worldwide. Anoctamin-1 is a calcium-activated channel and highly expressed in various tumors. A previous study indicated that suppressed Anoctamin-1 expression decreased cancer cell proliferation or migration. As a signal transduction and transcription activator, STAT6 is a novel agonist for Anoctamin-1 promoter. However, its role in tumor cell proliferation or migration remains unclear. Therefore, this study aimed to suppress STAT6 and Anoctamin-1 protein expression in gastric cancer cells to test the inhibitory effects on gastric cancer cell migration or invasion. MATERIALS AND METHODS: MTT colorimetry was used to test cell proliferation. Western blot was used to measure STAT6 and Anoctamin-1 expression before and after small interfering RNA (siRNA) treatment. A scratch assay was performed to measure cell migration, followed by Transwell chamber assay analysis of cell invasion. RESULTS: After STAT6 siRNA interference, the expression of STAT6 and Anoctamin-1 was significantly decreased in the gastric carcinoma cell line. Anoctamin-1 siRNA interference only decreased its protein expression, but not STAT6 protein expression. Interference of STAT6 or Anoctamin-1 reduced their protein expression and inhibited proliferation, migration, or invasion of gastric cancer cells. CONCLUSIONS: Inhibition of STAT6/Anoctamin-1 activation decreased proliferation, migration, or invasion of gastric cancer cells, suggesting that the STAT6/Anoctamin-1 pathway might be a novel target for treating gastric cancer. PMID- 29466036 TI - Pharmacokinetics of buprenorphine after intravenous and oral transmucosal administration in guinea pigs (Cavia porcellus). AB - OBJECTIVE To determine pharmacokinetics and sedative effects of buprenorphine after IV and oral transmucosal (OTM) administration in guinea pigs. ANIMALS 14 male guinea pigs (6 adults for preliminary experiment; eight 8 to 11-week-old animals for primary study). PROCEDURES A preliminary experiment was conducted to determine an appropriate buprenorphine dose. In the primary study, buprenorphine (0.2 mg/kg) was administered IV or OTM, and blood samples were obtained. The pH of the oral cavity was measured before OTM administration. Sedation was scored for 6 hours on a scale of 0 to 3 (0 = no sedation and 3 = heavy sedation). After a 7-day washout period, procedures were repeated in a crossover manner. Plasma buprenorphine concentration was quantified, and data were analyzed with a noncompartmental pharmacokinetic approach. RESULTS Mean peak plasma buprenorphine concentrations were 46.7 and 2.4 ng/mL after IV and OTM administration, respectively. Mean time to maximum plasma buprenorphine concentration was 1.5 and 71.2 minutes, and mean terminal half-life was 184.9 and 173.0 minutes for IV and OTM administration, respectively. There was a range of sedation effects (0 to 2) for both routes of administration, which resolved within the 6-hour time frame. CONCLUSIONS AND CLINICAL RELEVANCE On the basis of pharmacokinetic parameters for this study, buprenorphine at 0.2 mg/kg may be administered IV every 7 hours or OTM every 4 hours to maintain a target plasma concentration of 1 ng/mL. Further studies are needed to evaluate administration of multiple doses and sedative effects in guinea pigs with signs of pain. PMID- 29466037 TI - Time required to achieve maximum concentration of amikacin in synovial fluid of the distal interphalangeal joint after intravenous regional limb perfusion in horses. AB - OBJECTIVE To determine the maximum concentration (Cmax) of amikacin and time to Cmax (Tmax) in the distal interphalangeal (DIP) joint in horses after IV regional limb perfusion (IVRLP) by use of the cephalic vein. ANIMALS 9 adult horses. PROCEDURES Horses were sedated and restrained in a standing position and then subjected to IVRLP (2 g of amikacin sulfate diluted to 60 mL with saline [0.9% NaCl] solution) by use of the cephalic vein. A pneumatic tourniquet was placed 10 cm proximal to the accessory carpal bone. Perfusate was instilled with a peristaltic pump over a 3-minute period. Synovial fluid was collected from the DIP joint 5, 10, 15, 20, 25, and 30 minutes after IVRLP; the tourniquet was removed after the 20-minute sample was collected. Blood samples were collected from the jugular vein 5, 10, 15, 19, 21, 25, and 30 minutes after IVRLP. Amikacin was quantified with a fluorescence polarization immunoassay. Median Cmax of amikacin and Tmax in the DIP joint were determined. RESULTS 2 horses were excluded because an insufficient volume of synovial fluid was collected. Median Cmax for the DIP joint was 600 MUg/mL (range, 37 to 2,420 MUg/mL). Median Tmax for the DIP joint was 15 minutes. CONCLUSIONS AND CLINICAL RELEVANCE Tmax of amikacin was 15 minutes after IVRLP in horses and Cmax did not increase > 15 minutes after IVRLP despite maintenance of the tourniquet. Application of a tourniquet for 15 minutes should be sufficient for completion of IVRLP when attempting to achieve an adequate concentration of amikacin in the synovial fluid of the DIP joint. PMID- 29466040 TI - Determination of anatomic landmarks for optimal placement in captive-bolt euthanasia of goats. AB - OBJECTIVE To determine the optimal anatomic site and directional aim of a penetrating captive bolt (PCB) for euthanasia of goats. SAMPLE 8 skulls from horned and polled goat cadavers and 10 anesthetized horned and polled goats scheduled to be euthanized at the end of a teaching laboratory. PROCEDURES Sagittal sections of cadaver skulls from 8 horned and polled goats were used to determine the ideal anatomic site and aiming of a PCB to maximize damage to the midbrain region of the brainstem for euthanasia. Anatomic sites for ideal placement and directional aiming were confirmed by use of 10 anesthetized horned and polled goats. RESULTS Clinical observation and postmortem examination of the sagittal sections of skulls from the 10 anesthetized goats that were euthanized confirmed that perpendicular placement and firing of a PCB at the intersection of 2 lines, each drawn from the lateral canthus of 1 eye to the middle of the base of the opposite ear, resulted in consistent disruption of the midbrain and thalamus in all goats. Immediate cessation of breathing, followed by a loss of heartbeat in all 10 of the anesthetized goats, confirmed that use of this site consistently resulted in effective euthanasia. CONCLUSIONS AND CLINICAL RELEVANCE Damage to the brainstem and key adjacent structures may be accomplished by firing a PCB perpendicular to the skull over the anatomic site identified at the intersection of 2 lines, each drawn from the lateral canthus of 1 eye to the middle of the base of the opposite ear. PMID- 29466041 TI - Histologic investigation of airway inflammation in postmortem lung samples from racehorses. AB - OBJECTIVE To describe histologic findings in the small airways during postmortem examination of actively racing horses and to quantify the degree of airway inflammation by use of a semiquantitative scoring system. SAMPLE Lung tissues obtained from 95 horses (Thoroughbreds, Standardbreds, and Quarter Horses) that had been actively racing or training. PROCEDURES 10 standardized lung sections were obtained during postmortem examination of 37 horses that had been actively racing or training, and 2 histologic sections of the caudodorsal lung lobes previously collected from each of 58 horses that died or were euthanized during racing or training were also obtained. Sections were evaluated by use of a validated histologic small airway scoring system. RESULTS Scores for inflammatory cells, smooth muscle, and hemosiderin typically were high. Signalment and cause of death were not significant predictors of lung scores. Lung sample location was a significant predictor, with the highest scores in the caudal and dorsal sections. Inflammatory cell infiltration in peribronchiolar tissues, smooth muscle hyperplasia, and hemosiderin (prevalence of 86%, 98%, and 80%, respectively) were common findings in lungs of these horses, with the caudodorsal regions more severely affected. Correlation was moderate between smooth muscle hyperplasia and inflammatory cell infltration, with minimal correlation between hemosiderin and inflammatory cell infiltration. CONCLUSIONS AND CLINICAL RELEVANCE Inflammatory airway disease has been identified by use of bronchoalveolar lavage in young athletic horses throughout the world. In the study reported here, pathological changes were detected in the wall of small airways of horses that were actively training or racing.

PROCEDURES T1-weighted cartilage relaxation times were obtained for predetermined sites of the DIPJ before (T1preGd) and after (T1postGd) intra-articular gadolinium administration. Corresponding cartilage sites underwent macroscopic, histologic, and immunohistochemical evaluation, and cartilage glycosaminoglycan concentration and water content were determined. Median T1preGd and T1postGd were correlated with macroscopic, histologic, and biochemical data. Mixed generalized linear models were created to evaluate the effects of cartilage site, articular surface, and macroscopic and histologic scores on relaxation times. RESULTS 122 cartilage specimens were analyzed. Median T1postGd was lower than the median T1preGd for normal and diseased cartilage. Both T1preGd and T1postGd were correlated with macroscopic and histologic scores, whereby T1preGd increased and T1postGd decreased as osteoarthritis progressed. There was topographic variation of T1preGd and T1postGd within the DIPJ. Cartilage glycosaminoglycan concentration and water content were significantly correlated with T1preGd and macroscopic and histologic scores but were not correlated with T1postGd. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that dGEMRIC relaxation times varied for DIPJs with various degrees of osteoarthritis. These findings may help facilitate early detection of osteoarthritis. PMID- 29466043 TI - Neuropathologic features of the hippocampus and amygdala in cats with familial spontaneous epilepsy. AB - OBJECTIVE To investigate epilepsy-related neuropathologic changes in cats of a familial spontaneous epileptic strain (ie, familial spontaneous epileptic cats [FSECs]). ANIMALS 6 FSECs, 9 age-matched unrelated healthy control cats, and 2 nonaffected (without clinical seizures)dams and 1 nonaffected sire of FSECs. PROCEDURES Immunohistochemical analyses were used to evaluate hippocampal sclerosis, amygdaloid sclerosis, mossy fiber sprouting, and granule cell pathological changes. Values were compared between FSECs and control cats. RESULTS Significantly fewer neurons without gliosis were detected in the third subregion of the cornu ammonis (CA) of the dorsal and ventral aspects of the hippocampus as well as the central nucleus of the amygdala in FSECs versus control cats. Gliosis without neuronal loss was also observed in the CA4 subregion of the ventral aspect of the hippocampus. No changes in mossy fiber sprouting and granule cell pathological changes were detected. Moreover, similar changes were observed in the dams and sire without clinical seizures, although to a lesser extent. CONCLUSIONS AND CLINICAL RELEVANCE Findings suggested that the lower numbers of neurons in the CA3 subregion of the hippocampus and the central nucleus of the amygdala were endophenotypes of familial spontaneous epilepsy in cats. In contrast to results of other veterinary medicine reports, severe epilepsy-related neuropathologic changes (eg, hippocampal sclerosis, amygdaloid sclerosis, mossy fiber sprouting, and granule cell pathological changes) were not detected in FSECs. Despite the use of a small number of cats with infrequent seizures, these findings contributed new insights on the pathophysiologic mechanisms of genetic-related epilepsy in cats. PMID- 29466044 TI - Use of high-field and low-field magnetic resonance imaging to describe the anatomy of the proximal portion of the tarsal region of nonlame horses. AB - OBJECTIVE To use high-field and low-field MRI to describe the anatomy of the proximal portion of the tarsal region (proximal tarsal region) of nonlame horses. SAMPLE 25 cadaveric equine tarsi. PROCEDURES The proximal portion of 1 tarsus from each of 25 nonlame horses with no history of tarsal lameness underwent high field (1.5-T) and low-field (0.27-T) MRI. Resulting images were used to subjectively describe the anatomy of that region and obtain measurements of the collateral ligaments of the tarsocrural joint. RESULTS Long and short components of the lateral and medial collateral ligaments of the tarsocrural joint were identified. Various bundles of the short collateral ligaments were difficult to delineate on low-field images. Ligaments typically had low signal intensity in all sequences; however, multiple areas of increased signal intensity were identified at specific locations in most tarsi. This signal intensity was attributed to focal magic angle effect associated with orientation of collagen fibers within the ligaments at those locations. Subchondral bone of the distal aspect of the tibia was uniform in thickness, whereas that of the medial trochlear ridge of the talus was generally thicker than that of the lateral trochlear ridge. In most tarsi, subchondral bone of the talocalcaneal joint decreased in thickness from proximal to distal. CONCLUSIONS AND CLINICAL RELEVANCE Results generated in this study can be used as a reference for interpretation of MRI images of the proximal tarsal region in horses.

AB - OBJECTIVE To determine the pharmacokinetics of florfenicol, terbinafine, and betamethasone acetate after topical application to canine auricular skin and the influence of synthetic canine cerumen on pharmacokinetics. SAMPLE Auricular skin from 6 euthanized shelter dogs (3 females and 3 neutered males with no visible signs of otitis externa). PROCEDURES Skin adjacent to the external opening of the ear canal was collected and prepared for use in a 2-compartment flow-through diffusion cell system to evaluate penetration of an otic gel containing florfenicol, terbinafine, and betamethasone acetate over a 24-hour period. Radiolabeled 14C-terbinafine hydrochloride and 3H-betamethasone acetate were added to the gel to determine dermal penetration and distribution. Florfenicol absorption was determined by use of high-performance liquid chromatography-UV detection. Additionally, the effect of synthetic canine cerumen on the pharmacokinetics of all compounds was evaluated. RESULTS During the 24-hour experiment, mean +/- SD percentage absorption without the presence of synthetic canine cerumen was 0.28 +/- 0.09% for 3H-betamethasone acetate, 0.06 +/- 0.06% for florfenicol, and 0.06 +/- 0.02% for 14C-terbinafine hydrochloride. Absorption profiles revealed no impact of synthetic canine cerumen on skin absorption for all 3 active compounds in the gel or on skin distribution of 3H-betamethasone acetate and 14C-terbinafine hydrochloride. CONCLUSIONS AND CLINICAL RELEVANCE 3H betamethasone acetate, 14C-terbinafine hydrochloride, and florfenicol were all absorbed in vitro through healthy auricular skin specimens within the first 24 hours after topical application. Synthetic canine cerumen had no impact on dermal absorption in vitro, but it may serve as a temporary reservoir that prolongs the release of topical drugs. PMID- 29466047 TI - Optimized computed tomography protocol for assessment of dentition in alpacas. AB - OBJECTIVE To determine the optimal protocol for acquisition of CT images of the dentition in alpacas. ANIMALS 3 healthy adult male alpacas. PROCEDURES Each alpaca was anesthetized with an IM injection of a combination of ketamine, xylazine, and butorphanol and positioned in sternal recumbency on the CT couch with its legs folded in a natural cush position and its head positioned within the isocenter of the gantry of a 64-slice CT scanner. Images were acquired by means of 6 protocols (sequential and helical modes at slice thicknesses of 1.25, 2.5, and 5 mm). Five images (2 molar, 2 premolar, and mandibular incisor teeth) were selected from each protocol for evaluation by 3 veterinary radiologists. For each image, tooth root visibility and sharpness and image noise artifact were subjectively evaluated on a 3-point scoring system. RESULTS Slice thickness significantly affected tooth root visibility and tooth root sharpness but did not affect image noise artifact. Acquisition mode significantly affected tooth root visibility and tooth root sharpness as well as image noise artifact. Tooth root visibility and sharpness did not differ significantly between the helical and sequential images when the slice thickness was 1.25 mm. Image noise artifact was greater for helical images than sequential images but did not differ by slice thickness within either acquisition mode. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that for a 64-slice CT scanner, the optimal protocol for the acquisition of CT images of the dentition in alpacas was a sequential scan with a slice thickness of 1.25 mm. PMID- 29466048 TI - Effects of dexmedetomidine combined with commonly administered opioids on clinical variables in dogs. AB - OBJECTIVE To evaluate cardiopulmonary, sedative, and antinociceptive effects of dexmedetomidine combined with commonly administered opioids in dogs. ANIMALS 8 healthy Beagles. PROCEDURES Dogs were sedated by IM administration of each of 7 treatments. Treatments comprised dexmedetomidine (0.01 mg/kg; Dex) and the same dose of dexmedetomidine plus butorphanol (0.15 mg/kg; Dex-But), meperidine (5 mg/kg; Dex-Mep), methadone (0.5 mg/kg; Dex-Meth), morphine (0.5 mg/kg; Dex-Mor), nalbuphine (0.5 mg/kg; Dex-Nal), or tramadol (5 mg/kg; Dex-Tram). Cardiorespiratory and arterial blood gas variables and sedative and antinociceptive scores were measured before drug injection (time 0; baseline) and at 15-minute intervals for 120 minutes. RESULTS Heart rate was reduced at all time points after injection of Dex-But, Dex-Mep, Dex-Meth, and Dex-Mor treatments. There was a significant reduction of mean arterial blood pressure for Dex-But, Dex-Mep, and Dex-Mor treatments at all time points, compared with baseline. There was a significant decrease in respiratory rate, compared with the baseline value, for Dex, Dex-But, Dex-Meth, and Dex-Tram treatments from 15 to 120 minutes. A significant decrease in arterial blood pH was detected from baseline to 120 minutes for all treatments, with differences among Dex, Dex-Mep, and Dex-Mor. Reduction in Pao2 was greater for the Dex-Mep treatment than for the other treatments. The highest sedation scores were detected for Dex-Mep and Dex Meth treatments. Antinociceptive effects were superior for Dex-But, Dex-Meth, Dex Mor, and Dex-Nal treatments. CONCLUSIONS AND CLINICAL RELEVANCE Drug combinations caused similar cardiorespiratory changes, with greater sedative effects for Dex Mep and Dex-Meth and superior antinociceptive effects for Dex-But, Dex-Meth, Dex Mor, and Dex-Nal. PMID- 29466049 TI - Use of pressure mapping for quantitative analysis of pressure points induced by external coaptation of the distal portion of the pelvic limb of dogs. AB - OBJECTIVE To quantitatively measure the amount of pressure induced at the calcaneus and cranial tibial surface of dogs by use of 2 cast configurations. ANIMALS 13 client- or student-owned dogs. PROCEDURES Pressure sensors were placed over the calcaneus and cranial tibial surface. Dogs then were fitted with a fiberglass cast on a pelvic limb extending from the digits to the stifle joint (tall cast). Pressure induced over the calcaneus and proximal edge of the cast at the level of the cranial tibial surface was simultaneously recorded during ambulation. Subsequently, the cast was shortened to end immediately proximal to the calcaneus (short cast), and data acquisition was repeated. Pressure at the level of the calcaneus and cranial tibial surface for both cast configurations was compared by use of paired t tests. RESULTS The short cast created significantly greater peak pressure at the level of the calcaneus (mean +/- SD, 0.2 +/- 0.07 MPa), compared with peak pressure created by the tall cast (0.1 +/- 0.06 MPa). Mean pressure at the proximal cranial edge of the cast was significantly greater for the short cast (0.2 +/- 0.06 MPa) than for the tall cast (0.04 +/- 0.03 MPa). CONCLUSIONS AND CLINICAL RELEVANCE A cast extended to the level of the proximal portion of the tibia caused less pressure at the level of the calcaneus and the proximal cranial edge of the cast. Reducing the amount of pressure at these locations may minimize the potential for pressure sores and other soft tissue injuries. PMID- 29466050 TI - Letters to the Editor. PMID- 29466051 TI - Effect of a syringe aspiration technique versus a mechanical suction technique and use of N-butylscopolammonium bromide on the quantity and quality of bronchoalveolar lavage fluid samples obtained from horses with the summer pasture endophenotype of equine asthma. AB - OBJECTIVE To evaluate the effect of 2 bronchoalveolar lavage (BAL) sampling techniques and the use of N-butylscopolammonium bromide (NBB) on the quantity and quality of BAL fluid (BALF) samples obtained from horses with the summer pasture endophenotype of equine asthma. ANIMALS 8 horses with the summer pasture endophenotype of equine asthma. PROCEDURES BAL was performed bilaterally (right and left lung sites) with a flexible videoendoscope passed through the left or right nasal passage. During lavage of the first lung site, a BALF sample was collected by means of either gentle syringe aspiration or mechanical suction with a pressure-regulated wall-mounted suction pump. The endoscope was then maneuvered into the contralateral lung site, and lavage was performed with the alternate fluid retrieval technique. For each horse, BAL was performed bilaterally once with and once without premedication with NBB (21-day interval). The BALF samples retrieved were evaluated for volume, total cell count, differential cell count, RBC count, and total protein concentration. RESULTS Use of syringe aspiration significantly increased total BALF volume (mean volume increase, 40 mL [approx 7.5% yield]) and decreased total RBC count (mean decrease, 142 cells/MUL), compared with use of mechanical suction. The BALF nucleated cell count and differential cell count did not differ between BAL procedures. Use of NBB had no effect on BALF retrieval. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that retrieval of BALF by syringe aspiration may increase yield and reduce barotrauma in horses at increased risk of bronchoconstriction and bronchiolar collapse. Further studies to determine the usefulness of NBB and other bronchodilators during BAL procedures in horses are warranted. PMID- 29466052 TI - Long noncoding RNA SNHG1 promotes non-small cell lung cancer progression by up regulating MTDH via sponging miR-145-5p. AB - Long noncoding RNAs participate in the progression and initiation of non-small cell lung cancer (NSCLC), although the mechanism remains unknown. The lncRNA identified as small nucleolar RNA host gene 1 ( SNHG1) is a novel lncRNA that is increased in multiple human cancers; however, the regulatory mechanism requires further investigation. In this study, we discovered that SNHG1 was markedly up regulated in NSCLC tissues and cells and that SNHG1 silencing decreased tumor volumes. Moreover, we explored its regulatory mechanism and found that SNHG1 directly bound to microRNA (miRNA)-145-5p, isolating miR-145-5p from its target gene MTDH. Inhibition of SNHG1 suppressed NSCLC cell viability, proliferation, migration, and invasion in vitro, but its effect was rescued by miR-145-5p inhibition. These results demonstrate that SNHG1 contributes to NSCLC progression by modulating the miR-145-5p/ MTDH axis, and it could potentially be a therapeutic target as well as a diagnostic marker.-Lu, Q., Shan, S., Li, Y., Zhu, D., Jin, W., Ren, T. Long noncoding RNA SNHG1 promotes non-small cell lung cancer progression by up-regulating MTDH via sponging miR-145-5p. PMID- 29466053 TI - Interplay between gut microbiota and p66Shc affects obesity-associated insulin resistance. AB - The 66 kDa isoform of the mammalian Shc gene promotes adipogenesis, and p66Shc-/- mice accumulate less body weight than wild-type (WT) mice. As the metabolic consequences of the leaner phenotype of p66Shc-/- mice is debated, we hypothesized that gut microbiota may be involved. We confirmed that p66Shc-/- mice gained less weight than WT mice when on a high-fat diet (HFD), but they were not protected from insulin resistance and glucose intolerance. p66Shc deletion significantly modified the composition of gut microbiota and their modification after an HFD. This was associated with changes in gene expression of Il-1b and regenerating islet-derived protein 3 gamma ( Reg3g) in the gut and in systemic trimethylamine N-oxide and branched chain amino acid levels, despite there being no difference in intestinal structure and permeability. Depleting gut microbiota at the end of HFD rendered both strains more glucose tolerant but improved insulin sensitivity only in p66Shc-/- mice. Microbiota-depleted WT mice cohoused with microbiota-competent p66Shc-/- mice became significantly more insulin resistant than WT mice cohoused with WT mice, despite no difference in weight gain. These findings reconcile previous inconsistent observations on the metabolic phenotype of p66Shc-/- mice and illustrate the complex microbiome-host genotype interplay under metabolic stress.-Ciciliot, S., Albiero, M., Campanaro, S., Poncina, N., Tedesco, S., Scattolini, V., Dalla Costa, F., Cignarella, A., Vettore, M., Di Gangi, I.

PMID- 29466055 TI - Nature Versus Nurture: Have Performance Gaps Between Men and Women Reached an Asymptote? AB - Men outperform women in sports requiring muscular strength and/or endurance, but the relative influence of "nurture" versus "nature" remains difficult to quantify. Performance gaps between elite men and women are well documented using world records in second, centimeter, or kilogram sports. However, this approach is biased by global disparity in reward structures and opportunities for women. Despite policies enhancing female participation (Title IX legislation), US women only closed performance gaps by 2% and 5% in Olympic Trial swimming and running, respectively, from 1972 to 1980 (with no change thereafter through 2016). Performance gaps of 13% in elite middistance running and 8% in swimming (~4-min duration) remain, the 5% differential between sports indicative of load carriage disadvantages of higher female body fatness in running. Conversely, sprint swimming exhibits a greater sex difference than sprint running, suggesting anthropometric/power advantages unique to swim-block starts. The ~40-y plateau in the performance gap suggests a persistent dominance of biological influences (eg, longer limb levers, greater muscle mass, greater aerobic capacity, and lower fat mass) on performance. Current evidence suggests that women will not swim or run as fast as men in Olympic events, which speaks against eliminating sex segregation in these individual sports. Whether hormone reassignment sufficiently levels the playing field in Olympic sports for transgender females (born and socialized male) remains an issue to be tackled by sport-governing bodies. PMID- 29466054 TI - The role of Rpgrip1l, a component of the primary cilium, in adipocyte development and function. AB - Genetic variants within the FTO (alpha-ketoglutarate-dependent dioxygenase) gene have been strongly associated with a modest increase in adiposity as a result of increased food intake. These risk alleles are associated with decreased expression of both FTO and neighboring RPGRIP1L (retinitis pigmentosa GTPase regulator-interacting protein 1 like). RPGRIP1L encodes a protein that is critical to the function of the primary cilium, which conveys extracellular information to the cell. Rpgrip1l+/- mice exhibit increased adiposity, in part, as a result of hyperphagia. Here, we describe the effects of Rpgrip1l in adipocytes that may contribute to the adiposity phenotype observed in these animals and possibly in humans who segregate for FTO risk alleles. Loss of Rpgrip1l in 3T3-L1 preadipocytes increased the number of cells that are capable of differentiating into mature adipocytes. Knockout of Rpgrip1l in mature adipocytes using Adipoq-Cre did not increase adiposity in mice that were fed chow or a high-fat diet. We also did not observe any effects of Rpgrip1l knockdown in mature 3T3-L1 adipocytes. Thus, to the extent that Rpgrip1l affects cell autonomous adipose tissue function, it may do so as a result of the effects conveyed in preadipocytes in which the primary cilium is functionally important. We propose that decreased RPGRIP1L expression in preadipocytes in humans who segregate for FTO obesity risk alleles may increase the storage capacity of adipose tissue.-Martin Carli, J. F., LeDuc, C. A., Zhang, Y., Stratigopoulos, G., Leibel, R. L. The role of Rpgrip1l, a component of the primary cilium, in adipocyte development and function. PMID- 29466056 TI - A GUIDE TO FOLLOW-ON BIOLOGICS AND BIOSIMILARS WITH A FOCUS ON INSULIN. AB - OBJECTIVE: Many healthcare providers in the U.S. are not familiar with follow-on biologics and biosimilars nor with their critical distinctions from standard generics. Our aim is to provide a detailed review of both, with a focus on insulins in the U.S. regulatory system. METHODS: Literature has been reviewed to provide information on various aspects of biosimilars and a follow-on biologic of insulin. This will include structure, efficacy, cost, switching, and legal issues. RESULTS: Biologic products are large, complex molecules derived from living sources. Follow-on biologics are copies of the original innovator biologics. It is not possible to copy their structure exactly, leading to possible differences in efficacy and safety. Thus, regulations involving biologics are complex. Follow-on biologics are regulated under two Federal laws until March 23, 2020: the Public Health Service Act (PHS Act) and the Federal Food, Drug, and Cosmetic Act. Biosimilars are follow-on biologics which have been approved via the PHS Act. They consist of those which are "highly similar" to the reference drug and those which are "expected" to produce the same clinical result as the reference drug (interchangeable biosimilars). Interchangeable biosimilars have been determined by the U.S. Food and Drug Administration to be substitutable by the pharmacist "without the intervention" of the prescriber. From the patient perspective, switching to a follow-on biologic may necessitate a change in delivery device, which may create issues for patient adherence and dosing. CONCLUSION: Although they present several challenges in terms of regulation and acceptance, follow-on biologics have the potential to significantly reduce costs for patients requiring insulin therapy.

PMID- 29466057 TI - ZOLEDRONIC ACID VERSUS ALENDRONATE IN THE TREATMENT OF CHILDREN WITH OSTEOGENESIS IMPERFECTA: A 2-YEAR CLINICAL STUDY. AB - OBJECTIVE: Bisphosphonates have been demonstrated to increase the bone mineral density (BMD) of osteogenesis imperfecta (OI) patients. We aimed to compare the efficacy and safety of intravenous zoledronic acid and oral alendronate in patients with OI. METHODS: A total of 161 patients with OI ranging from 2 to 16 years old were included and randomized at a 2:1 ratio to receive either weekly oral alendronate (ALN) 70 mg or a once-yearly infusion of zoledronic acid (ZOL) for 2 years. The primary endpoints were percentage change from baseline in lumbar spine (LS) BMD and change in Z-scores of LS BMD. RESULTS: A total of 136 patients with OI completed the 2-year clinical study, 90 of whom were assigned to receive ALN, while 46 received ZOL treatment. The percentage change in LS BMD was 60.01 +/- 7.08% in the ALN group and 62.04 +/- 5.9% in the ZOL group ( P = .721). The corresponding BMD Z-score increased by 0.50 +/- 0.05 in the ALN group and 0.71 +/ 0.06 in the ZOL group ( P = .013). ZOL was superior to ALN in reducing the clinical fracture rate (hazard ratio, 0.23; 95% confidence interval, 0.118 to 0.431). There was no difference in the incidence of severe side effects between the two groups. CONCLUSION: A once-yearly 5 mg infusion of ZOL and weekly oral ALN had similar effects in increasing BMD and reducing bone resorption in children and adolescents with OI. ZOL was superior to ALN in reducing the clinical fracture rate.

PMID- 29466058 TI - CONSENSUS STATEMENT BY THE AMERICAN ASSOCIATION OF CLINICAL ENDOCRINOLOGISTS AND AMERICAN COLLEGE OF ENDOCRINOLOGY ON THE QUALITY OF DXA SCANS AND REPORTS. AB - OBJECTIVE: High-quality dual-energy X-ray absorptiometry (DXA) scans are necessary for accurate diagnosis of osteoporosis and monitoring of therapy; however, DXA scan reports may contain errors that cause confusion about diagnosis and treatment. This American Association of Clinical Endocrinologists/American College of Endocrinology consensus statement was generated to draw attention to many common technical problems affecting DXA report conclusions and provide guidance on how to address them to ensure that patients receive appropriate osteoporosis care. METHODS: The DXA Writing Committee developed a consensus based on discussion and evaluation of available literature related to osteoporosis and osteodensitometry. RESULTS: Technical errors may include errors in scan acquisition and/or analysis, leading to incorrect diagnosis and reporting of change over time. Although the International Society for Clinical Densitometry advocates training for technologists and medical interpreters to help eliminate these problems, many lack skill in this technology. Suspicion that reports are wrong arises when clinical history is not compatible with scan interpretation (e.g., dramatic increase/decrease in a short period of time; declines in previously stable bone density after years of treatment), when different scanners are used, or when inconsistent anatomic sites are used for monitoring the response to therapy. Understanding the concept of least significant change will minimize erroneous conclusions about changes in bone density. CONCLUSION: Clinicians must develop the skills to differentiate technical problems, which confound reports, from real biological changes. We recommend that clinicians review actual scan images and data, instead of relying solely on the impression of the report, to pinpoint errors and accurately interpret DXA scan images.

PMID- 29466059 TI - INITIATION OF PATIENTS ONTO LONG-ACTING SOMATOSTATIN ANALOGUE THERAPY FOR NEUROENDOCRINE TUMORS: A SINGLE-CENTER REVIEW OF PRACTICE. AB - OBJECTIVE: Neuroendocrine tumors (NETs) are being seen increasingly frequently, and recent data show that long-acting somatostatin analogues have become a major initial treatment, regardless of whether the tumors are functioning or not. However, test dosing with subcutaneous (sc) octreotide is usually advised to assess longer-term tolerability, although this advice is mainly based on results with functioning tumors. The aim of the study was to assess the value of an initiating test dose of sc octreotide on the prediction of subsequent adverse events after treatment with the long-acting analogue. METHODS: In a single, large Centre of Excellence for NETs, a first cohort of patients (n = 24) was admitted overnight after an sc injection of octreotide, and then administered the analogue; a subsequent group (n = 53) had the test dose performed on an outpatient basis. Side effects were recorded after the test dose and subsequent treatment with the long-acting analogue. RESULTS: The test dose injection was of little value in predicting adverse events following the long-acting somatostatin analogue. CONCLUSION: Unless there are serious symptoms associated with a functioning NET, it is unnecessary to carry out a test dose; a change to this procedure will improve resource allocation and should enhance early initiation onto maintenance therapy.

PMID- 29466062 TI - MANAGEMENT OF DIABETES DURING AIR TRAVEL: A SYSTEMATIC LITERATURE REVIEW OF CURRENT RECOMMENDATIONS AND THEIR SUPPORTING EVIDENCE. AB - OBJECTIVE: Individuals with diabetes are increasingly seeking pretravel advice, but updated professional recommendations remain scant. We performed a systematic review on diabetes management during air travel to summarize current recommendations, assess supporting evidence, and identify areas of future research. METHODS: A systematic review of the English literature on diabetes management during air travel was undertaken utilizing PubMed and MEDLINE. Publications regarding general travel advice; adjustment of insulin and noninsulin therapies; and the use of insulin pumps, glucometers and subcutaneous glucose sensors at altitude were included. Gathered information was used to create an updated summary of glucose-lowering medication adjustment during air travel. RESULTS: Sixty-one publications were identified, most providing expert opinion and few offering primary data (47 expert opinion, 2 observational studies, 2 case reports, 10 device studies). General travel advice was uniform, with increasing attention to preflight security. Indications for oral antihyperglycemic therapy adjustments varied. There were few recommendations on contemporary agents and on nonhypoglycemic adverse events. There was little consensus on insulin adjustment protocols, many antedating current insulin formulations. Most publications advocated adjusting insulin pump time settings after arrival; however, there was disagreement on timing and rate adjustments. Glucometers and subcutaneous glucose sensors were reported to be less accurate at altitude, but not to an extent that would preclude their clinical use. CONCLUSION: Recommendations for diabetes management during air travel vary significantly and are mostly based on expert opinion. Data from systematic investigation on glucose-lowering medication adjustment protocols may support the development of a future consensus statement.

PMID- 29466063 TI - Antiulcerative and Antinociceptive Activities of Casein and Whey Proteins. AB - The aim of this study was to evaluate the antiulcerative and antinociceptive activities of milk proteins using the induced gastric ulcer with ethanol rat model and the acetic acid-induced writhing mouse model. Casein (CN), (100, 300, and 1000 mg kg-1) doses presented antiulcerative activity on a dose-dependent manner with values of 30.8%, 41.4%, and 57.0% of inhibition measured using the ulcerative lesions index (ULI), respectively. Whey protein concentrate (WPC), (100, 300, and 1000 mg kg-1) doses presented antiulcerative activity on a dose dependent manner with values of 48.9%, 65.5%, and 68.22% of ULI inhibition, respectively. CN, casein hydrolysates (CNH), WPC, and whey protein hydrolysates (WPH), (3, 10, and 30 mg kg-1) doses presented antinociceptive activity using the acetic acid-induced writhing in the mouse model. CN (30 mg kg-1) presented a value of 40% of inhibition writhing, and CNH (30 mg kg-1) presented antinociceptive activity with a value up to 46% of writhing inhibition. WPC (30 mg kg-1) presented a value of 52.50%, and WPH (30 mg kg-1) presented antinociceptive activity with a value up to 88.00% of writhing inhibition. In conclusion, CN and WPC demonstrated in vivo antiulcerative properties and represent a promising alternative to be used as protectors of the gastric mucosa. CNH and WPH demonstrated in vivo antiulcerative properties and represent a promising alternative to be used as natural analgesic. PMID- 29466064 TI - Exploring and Adapting a Conceptual Model of Sexual Positioning Practices and Sexual Risk Among HIV-Negative Black Men Who Have Sex With Men. AB - Estimates show a 50% lifetime human immunodeficiency virus (HIV) risk among Black men who have sex with men (BMSM) in the United States(U.S.). Studying the dynamics of sexual positioning practices among BMSM could provide insights into the disparities observed among U.S. groups of men who have sex with men (MSM). This study explored sexual positioning dynamics among HIV-negative BMSM and how they aligned with a theoretical model of sexual positioning and HIV/sexually transmitted infection (STI) risk among MSM. In-depth qualitative interviews were conducted with 29 HIV-negative BMSM between ages 25 and 35 in Los Angeles. Comments related to sexual behaviors were reviewed for relevance regarding oral or anal sexual positioning practices. Data presented represent the range of themes related to decision making regarding sexual positioning. Personal preference, partner attraction, HIV avoidance, and feeling obligated to practice partner preferences influenced sexual positioning. Drug use also affected decision making and was sometimes preferred in order to practice receptive anal intercourse. These variables build on the conceptual model of sexual positioning practices and sexual risk, and add understanding to the relationship between preferences, practices, and risk management. Future research on risk among HIV negative BMSM should quantify the relative impact of personal preferences, partner attraction, partner type, compromise, and substance use on sexual positioning practices and risk. PMID- 29466065 TI - Physical Preparation Factors That Influence Technical and Physical Match Performance in Professional Australian Football. AB - OBJECTIVES: To examine the collective influence of a range of physical preparation elements on selected performance measures during Australian football match play. DESIGN: Prospective and longitudinal. METHODS: Data were collected from 34 professional Australian football players from the same club during the 2016 Australian Football League competition season. Match activity profiles and acute (7-d) and chronic (3-wk) training loads were collected using global positioning system devices. Training response was measured by well-being questionnaires completed prior to the main training session each week. Maximal aerobic running speed (MAS) was estimated by a 2-km time trial conducted during preseason. Coach ratings were collected from the senior coach and 4 assistants after each match on a 5-point Likert scale. Player ratings were obtained from a commercial statistics provider. Fifteen matches were analyzed. Linear mixed models were constructed to examine the collective influence of training-related factors on 4 performance measures. RESULTS: Muscle soreness had a small positive effect (ES: 0.12) on Champion Data rating points. Three-week average high-speed running distance had a small negative effect (ES: 0.14) on coach ratings. MAS had large to moderate positive effects (ES: 0.55 to 0.47) on relative total and high speed running distances. Acute total and chronic average total running distance had small positive (ES: 0.13) and negative (ES: 0.14) effects on relative total and high-speed running distance performed during matches, respectively. CONCLUSIONS: MAS should be developed to enhance players' running performance during competition. Monitoring of physical preparation data may assist in reducing injury and illness and increasing player availability but not enhance football performance. PMID- 29466066 TI - Effect of Graft Type on Balance and Hop Tests in Adolescent Males following Anterior Cruciate Ligament Reconstruction. AB - CONTEXT: Recent epidemiology studies indicated a steady increase of anterior cruciate ligament (ACL) injury in young athletes. ACL reconstruction (ACLR) is currently a standard of the care, but effect of ACLR graft including bone patellar tendon bone (BTB), hamstring tendon (HT), or iliotibial band (ITB) on balance and hop performance is understudied. OBJECTIVE: To compare balance and hop deficits between uninvolved and reconstructed limbs in each autograft type (aim 1) and among the three autograft groups (aim 2). SETTING: Biomechanical laboratory. PARTICIPANTS: Male ACLR patients who are younger than 22 years old (Total N=160; BTB N=19, HT N=108, ITB N=33). INTERVENTION: Approximately 6-9 months following ACLR, Y-balance and 4 types of hop tests were measured bilaterally. MAIN OUTCOME MEASURES: Limb symmetry index of balance and hop tests within each graft type and between the 3 graft types. RESULTS: In the BTB group, significant anterior reach, single hop, triple hops, and cross-over hops deficits were observed on the ACLR limb compared to uninvolved limb. The HT group showed significant deficits in single hop, triple hops, and cross-over hops on the ACLR limb relative to the uninvolved limb. Compared to uninvolved limb, significantly decreased triple hops and 6 meter timed hop deficits in the ACLR limb were recorded in the ITB group. When controlling for confounders and comparing among the three autograft types, the only significant difference was anterior reach, in which the BTB group showed significant deficits. CONCLUSION: Compared to the uninvolved limb, significant hop deficits in ACLR limb were prevalent among adolescent ACLR patients at approximately 6-9 months postoperatively. After controlling covariates, significantly reduced anterior reach balance was found in BTB group as compared to the HT and ITB groups. PMID- 29466067 TI - A Narrative Analysis: Examining the Transition to Practice for the Full-Time Secondary School Athletic Trainer. AB - CONTEXT: The transition to clinical practice is an important topic in athletic training because it is viewed as a stressful time that is accompanied by self doubt. Mentorship and previous experience support the transition to practice, but little information is available on the organizational entry of the athletic trainer (AT) who is employed full time in the secondary school setting. OBJECTIVE: To understand the experiences of newly credentialed ATs in full-time positions in the secondary school setting. DESIGN: Qualitative study. SETTING: Secondary schools. PATIENTS OR OTHER PARTICIPANTS: Seventeen ATs (4 men, 13 women; age = 25 +/- 4 years) were employed full time in the secondary school setting. On average, the full-time ATs worked 40 +/- 10 hours per week. DATA COLLECTION AND ANALYSIS: All participants completed a semistructured telephone interview with 1 researcher. Data were analyzed using a narrative analysis, and credibility was established by peer review and researcher triangulation. The narrative research paradigm guided our protocol and supported the rigor of the study. RESULTS: Our analyses revealed that transition to practice was organic, such that the newly credentialed AT gained awareness by engaging in the role daily. Additionally, the transition process was facilitated by previous experience in the setting, mostly from educational training. Ongoing communication with various stakeholders (athletic directors, team physicians, and peer ATs) in the setting also assisted in the process of transitioning. Finally, mentorship from previous preceptors provided support during the transition process. CONCLUSIONS: Transitioning into full-time clinical practice in the secondary school setting was informal and supported by professional relationships and past experiences. Past experiences allowed for awareness but also the development of mentoring relationships that continued beyond the clinical education experience. Communication also assisted the newly credentialed AT, as it provided feedback for legitimation by multiple stakeholders. PMID- 29466068 TI - Capture of Time-Loss Overuse Soccer Injuries in the National Collegiate Athletic Association's Injury Surveillance System, 2005-2006 Through 2007-2008. AB - CONTEXT: Overuse injuries are reported to account for nearly 50% of sports injuries and, due to their progressive nature and the uncertainty regarding date of onset, are difficult to define and categorize. Comparing the capture rates of overuse injuries between injury-surveillance systems and medical records can clarify completeness and determinants of how overuse injuries are represented in injury-surveillance data. OBJECTIVE: To estimate the capture rate of time-loss medical-attention overuse injuries in men's and women's soccer in the National Collegiate Athletic Association Injury Surveillance System (NCAA ISS) compared with medical records maintained by certified athletic trainers and assess the differences in completeness of capture and factors contributing to those differences. DESIGN: Capture-recapture study. SETTING: Fifteen NCAA institutions provided NCAA ISS and medical record data from men's and women's soccer programs from 2005-2006 through 2007-2008. PATIENTS OR OTHER PARTICIPANTS: National Collegiate Athletic Association men's and women's soccer players. MAIN OUTCOME MEASURE(S): Time-loss medical-attention overuse injuries were defined as injuries with an overuse mechanism of injury in the NCAA ISS or medical records. Capture rates were calculated as the proportion of total overuse injuries classified as having overuse mechanisms in the NCAA ISS and the NCAA ISS and medical records combined. RESULTS: The NCAA ISS captured 63.7% of the total estimated overuse mechanisms of injury in men's and women's soccer players. The estimated proportion of overuse injury mechanisms captured by both the NCAA ISS and medical records was 37.1%. The NCAA ISS captured more overuse injury mechanisms in men's soccer than in women's soccer (79.2% versus 45.0%, chi2 = 9.60; P = .002) athletes. CONCLUSIONS: From 2005-2006 through 2007-2008, the NCAA ISS captured only two thirds of time-loss medical-attention overuse mechanisms of injury in men's and women's soccer players. Future researchers should consider supplementing injury-surveillance data with a clinical record review to capture the burden of these injuries. PMID- 29466069 TI - Maintaining Professional Commitment as a Newly Credentialed Athletic Trainer in the Secondary School Setting. AB - CONTEXT: Professional commitment, or one's affinity and loyalty to a career, has become a topic of interest in athletic training. The expanding research on the topic, however, has omitted newly credentialed athletic trainers (ATs). For an impressionable group of practitioners, transitioning to clinical practice can be stressful. OBJECTIVE: To explore the professional commitment of newly credentialed ATs in the secondary school setting. SETTING: Secondary school. DESIGN: Qualitative study. PATIENTS OR OTHER PARTICIPANTS: A total of 31 newly credentialed ATs (6 men, 25 women; mean age = 24 +/- 3 years) participated. Of these, 17 ATs (4 men, 13 women; mean age = 25 +/- 4 years) were employed full time in the secondary school setting, and 14 ATs (2 men, 12 women; mean age = 23.0 +/- 2.0 years) were graduate assistant students in the secondary school setting. DATA COLLECTION AND ANALYSIS: All participants completed semistructured interviews, which focused on their experiences in the secondary school setting and transitioning into the role and setting. Transcripts were analyzed using the phenomenologic approach. Creditability was established by peer review, member checks, and researcher triangulation. RESULTS: Four main findings related to the professional commitment of newly credentialed ATs in the secondary school setting were identified. Work-life balance, professional relationships formed with the student-athletes, enjoyment gained from working in the secondary school setting, and professional responsibility emerged as factors facilitating commitment. CONCLUSIONS: Affective commitment is a primary facilitator of professional commitment. Newly credentialed ATs who enjoy their jobs and have time to engage in nonwork roles are able to maintain a positive professional commitment. Our findings align with the previous literature and help strengthen our understanding that rejuvenation and passion are important to professional commitment. PMID- 29466071 TI - Dynamics of the Metabolic Response During a Competitive 100-m Freestyle in Elite Male Swimmers. AB - PURPOSE: To compare the dynamics of maximal oxygen uptake ([Formula: see text]), blood lactate ([La]b), total energy expenditure (Etot), and contributions of the aerobic (Eaer), alactic anaerobic (Ean,al), and lactic anaerobic (Ean,lac) metabolic energy pathways over 4 consecutive 25-m laps (L0-25, L25-50, etc) of a 100-m maximal freestyle swim. METHODS: Elite swimmers comprising 26 juniors (age = 16 [1] y) and 23 seniors (age = 24 [5] y) performed 100 m at maximal speed and then 3 trials (25, 50, and 75 m) at the same pace as that of the 100 m. [La]b was collected, and [Formula: see text] was measured 20 s postexercise. RESULTS: The estimated energetic contributions for the 100-m trial are presented as mean (SD): Eaer, 51% (8%); Ean,al, 18% (2%); Ean,lac, 31% (9%). [Formula: see text] increased from L0-25 to L25-50 (mean = 3.5 L.min-1; 90% confidence interval [CI], 3.4-3.7 L.min-1 to mean = 4.2 L.min-1; 90% CI, 4.0-4.3 L.min-1) and then stabilized in the 2nd 50 m (mean = 4.1 L.min-1; 90% CI, 3.9-4.3 L.min-1 to mean = 4.2 L.min-1; 90% CI, 4.0-4.4 L.min-1). Etot (juniors, 138 [18] kJ; seniors, 168 [26] kJ), Ean,al (juniors, 27 [3] kJ; seniors, 30 [3] kJ), and Ean,lac (juniors, 38 [12] kJ; seniors, 62 [24] kJ) were 11-58% higher in seniors. Faster swimmers (n = 26) had higher [Formula: see text], 90% CI 4.4-4.8 L.min-1 [Formula: see text] L.min-1, 90% CI 3.6-4.2 L.min-1), and Eaer power was associated with fast performances (P < .001). CONCLUSION: Faster swimmers were characterized by higher [Formula: see text] and less time to reach the highest [Formula: see text] at ~50 m of the 100-m swim. Anaerobic qualities become more important with age. PMID- 29466070 TI - Orientation Process for Newly Credentialed Athletic Trainers in the Transition to Practice. AB - CONTEXT: Orientation is an important part of socialization and transition to practice, yet the orientation process for newly credentialed athletic trainers (ATs) is unknown. OBJECTIVE: To determine how newly credentialed ATs are oriented to their roles. DESIGN: Cross-sectional study. SETTING: Online survey. PATIENTS OR OTHER PARTICIPANTS: Three hundred thirty-two of 1835 newly credentialed ATs (18%) certified and employed between January and September of 2013 completed the survey (129 men, 203 women; age = 23.58 +/- 2.54 years). DATA COLLECTION AND ANALYSIS: The survey consisted of demographic information (eg, employment setting, job title) and 2 sections: (1) orientation tactics and (2) usefulness of orientation tactics. For the first section, participants identified if various orientation tactics were included in their orientations (eg, policies and procedures review). For the second section, participants identified how useful each orientation tactic was on a Likert scale (1 = not useful, 4 = very useful). Descriptive statistics were calculated for each survey item. Mann Whitney U and Kruskal-Wallis tests were used to determine differences between demographic characteristics and orientation tactics. A Bonferroni correction accounted for multiple comparisons. A panel of experts established the content validity of the survey. The Cronbach alpha was used to establish internal consistency (alpha = 0.802) Results: The most common orientation tactics were meeting with supervisors (n = 276, 82.9%) and staff members (eg, coaches; n = 266, 79.9%) and learning responsibilities (n = 254, 76.2%). The least common orientation tactics were simulation of the emergency action plan (n = 66, 19.8%) and preceptor development (n = 71, 21.3%); however, preceptor development was not applicable to many participants. The most useful orientation tactics were simulating the emergency action plan (3.45/4.0) and meeting with staff members (3.44/4.0). Participants who felt their orientation prepared them for their roles were exposed to more tactics during orientation (Mann-Whitney U = 17 212, P < .001). CONCLUSIONS: Many tactics were used to orient newly credentialed ATs to their roles, but orientations varied based on the practice setting. PMID- 29466072 TI - A Novel Auxiliary Device for Preventing Band Slippage After Laparoscopic Adjustable Gastric Banding: Infra-Band Fixation Using S-Loop. AB - BACKGROUND: Band slippage is known to be a troublesome complication of laparoscopic adjustable gastric banding (LAGB), often requiring surgical intervention. To prevent band slippage, a new auxiliary device "S-loop" was developed. METHODS: From July 2010 to January 2014, a total of 814 LAGBs were performed by a single surgeon. The patients were divided into two groups based on the application of S-loop: conventional LAGB group (n = 378) and S-loop group (n = 436). The operative outcomes were compared between the two groups. RESULTS: The mean operative time and the length of hospital stay were significantly longer in the conventional LAGB group than in the S-loop group (64.3 minutes versus 57.1 minutes; P < .001 and 5.0 hours versus 3.6 hours; P < .001, respectively). The complications occurred in 7.1% of the conventional LAGB group and 1.6% in the S loop group (P < .001). Slippage was the most common complication: 13 cases were observed in the conventional LAGB group, whereas no slippage was observed in the S-loop group. CONCLUSION: Infra-band fixation using S-loop is a simple and effective method for preventing band slippage compared with the conventional LAGB. PMID- 29466073 TI - The Effects of Hip Mobilizations on Patient Outcomes: A Critically Appraised Topic. AB - Clinical Scenario: Hip osteoarthritis currently affects up to 28% percent of the population, and the number of affected Americans is expected to rise as the American population increases and ages.1,2 Limited hip range of motion (ROM) has been identified as a predisposing factor to hip osteoarthritis and limited patient function.3,4 Clinicians often apply therapy techniques, such as stretching and strengthening exercises, to improve hip ROM.5 Although traditional therapy has been recommended to improve hip ROM, the efficiency of the treatments within the literature are questionable due to lack of high quality studies.3-8 More recently, clinicians have begun to utilize joint mobilization and the Mulligan Concept (MC) mobilization with movement (MWM) techniques to increase ROM at the hip;3-8 however, there is a paucity of research on the lasting effects of mobilizations. Given the difficulties in improving ROM immediately (within a single treatment), and with long-lasting results (over the course of months), 3-8 it is imperative to examine the evidence for the effectiveness of traditional therapy techniques and more novel manual therapy techniques. Focused Clinical Question: Is there evidence to suggest manual mobilizations techniques at the hip are effective at treating hip ROM limitations? PMID- 29466074 TI - Prevalence and Survival Impact of Pretreatment Cancer-Associated Weight Loss: A Tool for Guiding Early Palliative Care. AB - PURPOSE: Cancer-associated weight loss is associated with poor prognosis in advanced malignancy; however, its pretreatment prevalence and survival impact are inadequately described in large cohorts. Such data, stratified by tumor type and stage, may facilitate the optimal and timely allocation of complementary care, leading to improvements in patient survival and quality of life. METHODS: We performed a retrospective cohort study of 3,180 consecutively treated adult patients with lung or GI (including colorectal, liver, and pancreatic) cancer. Pretreatment cancer-associated weight loss was based on the international consensus definition of cachexia. Prevalence and survival impact of pretreatment cancer-associated weight loss were evaluated using the Kaplan-Meier method and compared using log-rank test. RESULTS: Cancer-associated weight loss was observed at the time of cancer diagnosis in 34.1% of patients. Pretreatment weight loss was documented in 17.6%, 25.8%, 36.6%, and 43.3% of stage I, II, III, and IV cancers, respectively. Wasting was common regardless of tumor type, with prevalence at diagnosis ranging from 27.3% in patients with colorectal cancer to 53.4% in patients with gastroesophageal cancer. Pretreatment weight loss was associated with reduced overall survival after adjusting for stage, size, grade, comorbidity, age, sex, and tobacco history (hazard ratio, 1.26; 95% CI, 1.13 to 1.39). CONCLUSION: Pretreatment cancer-associated weight loss is common, even in early-stage disease, and is independently associated with reduced survival. Minimal weight loss represents a clinically distinct entity with an associated overall survival intermediate to that of no weight loss and overt wasting. Early diagnosis and treatment of cancer-associated wasting offers a novel therapeutic avenue for reducing cancer mortality. PMID- 29466076 TI - The Effects of Rigid Scapular Taping on the Subacromial Space in Athletes With and Without Rotator Cuff Tendinopathy: A Randomized-Controlled Study. AB - CONTEXT: Reduction of the subacromial space (SAS) during arm elevation may contribute to rotator cuff tendinopathy. The effects of scapular taping on the SAS in athletes with and without RC tendinopathy is unknown. OBJECTIVES: To investigate the immediate effects of scapular taping on the SAS in athletes with and without RC tendinopathy. DESIGN: Randomized-controlled with repeated measures. SETTING: University laboratory. PARTICIPANTS: Forty-three male volleyball players (17 asymptomatic and 26 with RC tendinopathy, mean age = 22.9+/-3.5 years) participated in the study. INTERVENTION: Three scapular taping protocols - no taping (control), taping with tension (therapeutic taping) and taping without tension (sham taping). MAIN OUTCOME MEASURES: Ultrasound measurements of the SAS with the arm at 0 degrees and 60 degrees of shoulder abduction, and the change in the SAS between 0 degrees and 60 degrees of shoulder abduction (SAS0 degrees -60 degrees ) were calculated. RESULTS: Athletes with RC tendinopathy demonstrated larger SAS with therapeutic taping at 60 degrees of shoulder abduction (6.9+/-1.9 mm vs. 5.8+/-1.7 mm, mean difference = 1.1 mm, 95% CI = -1.80 - -0.39, p=0.002) when compared to the no taping condition. The tendinopathy group also showed less reduction in the SAS with therapeutic taping during SAS0 degrees -60 degrees (2.0+/-1.4 mm vs. 2.8+/-1.4 mm, p=0.023) when compared to the no taping condition. When tape was applied to the scapula in asymptomatic athletes, our results showed a relatively small increase in the SAS with therapeutic taping during arm resting at 0 degrees of abduction when compared to the no taping condition (8.7+/-0.9 mm vs. 8.3+/-0.8 mm, mean difference = 0.4 mm, 95% CI = -0.71 - -0.11, p=0.008). CONCLUSIONS: Athletes with RC tendinopathy demonstrated less reduction of the SAS with rigid scapular taping during early arm abduction. Such observation was not evidenced in asymptomatic athletes. PMID- 29466077 TI - Do People Inherently Dislike Uncertain Advice? AB - Research suggests that people prefer confident to uncertain advisors. But do people dislike uncertain advice itself? In 11 studies ( N = 4,806), participants forecasted an uncertain event after receiving advice and then rated the quality of the advice (Studies 1-7, S1, and S2) or chose between two advisors (Studies 8 9). Replicating previous research, our results showed that confident advisors were judged more favorably than advisors who were "not sure." Importantly, however, participants were not more likely to prefer certain advice: They did not dislike advisors who expressed uncertainty by providing ranges of outcomes, giving numerical probabilities, or saying that one event is "more likely" than another. Additionally, when faced with an explicit choice, participants were more likely to choose an advisor who provided uncertain advice over an advisor who provided certain advice. Our findings suggest that people do not inherently dislike uncertain advice. Advisors benefit from expressing themselves with confidence, but not from communicating false certainty. PMID- 29466078 TI - Recovery of Cycling Gross Efficiency After Time-Trial Exercise. AB - BACKGROUND: Research has shown that gross efficiency (GE) declines during high intensity exercise, but the time course of recovery of GE after high-intensity exercise has not yet been investigated. PURPOSE: To determine the time course of the recovery of GE after time trials (TTs) of different lengths. METHODS: Nineteen trained male cyclists participated in this study. Before and after TTs of 2000 and 20,000 m, subjects performed submaximal exercise at 55% of the power output attained at maximal oxygen uptake (PVO2max). The postmeasurement continued until 30 min after the end of the TT, during which GE was determined over 3-min intervals. The magnitude-based-inferences approach was used for statistical analysis. RESULTS: GE decreased substantially during the 2000-m and 20,000-m TTs (-11.8% [3.6%] and -6.2% [4.0%], respectively). A most likely and very likely recovery of GE was found during the first half of the submaximal exercise bout performed after the 2000-m, with only a possible increase in GE during the first part of the submaximal exercise bout performed after the 20,000-m. After both distances, GE did not fully recover to the initial pre-TT values, as the difference between the pre-TT value and average GE value of minutes 26-29 was still most likely negative for both the 2000- and 20,000-m (-6.1% [2.8%] and 7.0% [4.5%], respectively). CONCLUSIONS: It is impossible to fully recover GE after TTs of 2000- or 20,000-m during 30 min of submaximal cycling exercise performed at an intensity of 55% PVO2max. PMID- 29466079 TI - Reduced Fatigue in Passive Versus Active Recovery: An Examination of Repeated Change-of-Direction Sprints in Basketball Players. AB - PURPOSE: To investigate the physiological and performance effects of active and passive recovery between repeated-change-of-direction sprints. METHODS: Eight semiprofessional basketball players (age: 19.9 [1.5] y; stature: 183.0 [9.6] cm; body mass: 77.7 [16.9] kg; body fat: 11.8% [6.3%]; and peak oxygen consumption: 46.1 [7.6] mL.kg-1.min-1) completed 12 * 20-m repeated-change-of-direction sprints (Agility 5-0-5 tests) interspersed with 20 seconds of active (50% maximal aerobic speed) or passive recovery in a randomized crossover design. Physiological and perceptual measures included heart rate, oxygen consumption, blood lactate concentration, and rating of perceived exertion. Change-of direction speed was measured during each sprint using the change-of-direction deficit (CODD), with summed CODD time and CODD decrement calculated as performance measures. RESULTS: Average heart rate (7.3 [6.4] beats.min-1; P = .010; effect size (ES) = 1.09; very likely) and oxygen consumption (4.4 [5.0] mL.kg-1.min-1; P = .12; ES = 0.77; unclear) were moderately greater with active recovery compared with passive recovery across sprints. Summed CODD time (0.87 [1.01] s; P = .07; ES = 0.76, moderate; likely) and CODD decrement (8.1% [3.7%]; P < .01; ES = 1.94, large; almost certainly) were higher with active compared with passive recovery. Trivial-small differences were evident for rating of perceived exertion (P = .516; ES = 0.19; unclear) and posttest blood lactate concentration (P = .29; ES = 0.40; unclear) between recovery modes. CONCLUSIONS: Passive recovery between repeated-change-of-direction sprints may reduce the physiological stress and fatigue encountered compared with active recovery in basketball players. PMID- 29466080 TI - Does Pre-Cooling With Whole-Body Immersion Affect Thermal Sensation or Perceived Exertion?: A Critically-Appraised Topic. AB - : Clinical Scenario: Exertional heat stroke (EHS) is a potentially deadly heat illness and poses a significant health risk to athletes; EHS survival rates are near 100% if properly recognized and treated.1 Whole body cold water immersion (CWI) is the most effective method of lowering body core temperature.2 Precooling (PC) with CWI before exercise may prevent severe hyperthermia and/or EHS by increasing the body's overall heat-storage capacity.3 However, PC may also alter athletes' perception of how hot they feel or how hard they are exercising. Consequently, they may be unable to accurately perceive their body core temperature or how hard they are working which may predispose them to severe hyperthermia or EHS. CLINICAL QUESTION: Does PC with whole-body CWI affect thermal sensation (TS) or rating of perceived exertion (RPE) during exercise in the heat? SUMMARY OF FINDINGS: In four studies,4-7 RPE during exercise ranged from 12 +/- 2 to 20 +/- 3 with no clinically meaningful differences between PC and control trials. Thermal sensation scores ranged from 2 +/- 1 to 8 +/- 0.5 in control trials and from 2 +/- 1 to 7.5 +/- 0.5 during PC trials. Clinical Bottom Line: Precooling did not cause clinically-meaningful differences in RPE or TS during exercise. It is unlikely PC would predispose athletes to EHS by altering perceptions of exercise intensity or body core temperature. Strength of Recommendation: None of the reviewed studies4-7 (all level 2 studies with PEDro scores >=5) suggest PC with CWI influences RPE or TS in exercising males. PMID- 29466081 TI - Kinesio Taping Improves Perceptions of Pain and Function of Patients with Knee Osteoarthritis. A Randomized, Controlled Trial. AB - CONTEXT: Although increasingly used for therapeutic treatment only limited evidence exists regarding the effects of kinesio taping on patients with knee osteoarthritis. OBJECTIVE: To determine the effects of kinesio taping on pain, function, gait and neuromuscular control concerning patients with knee osteoarthritis (OA). DESIGN: Randomized sham-controlled trial. SETTING: University laboratory. PARTICIPANTS: 141 Patients (65.1+/-7.0 years) with a clinical and radiographic diagnosis of knee osteoarthritis. INTERVENTION: Kinesio tape, sham tape or no tape for 3 consecutive days. MAIN OUTCOME MEASURES: Self reported pain, stiffness and function were measured by the Western Ontario and McMaster Universities Arthritis Index (WOMAC). Further tests included the Balance Error Scoring System (BESS-Test), 10-m Walk Test (10MWT), the maximum voluntary isometric contraction force (MVIC) of the quadriceps femoris and knee active range of motion (active ROM). RESULTS: At baseline, there were no differences in all outcomes between groups except for knee flexion. Significant effects were found for WOMAC pain (tape vs. sham p=0.053; tape vs. control p=0.047), stiffness (tape vs. sham p=0.012; tape vs. control p<=0.001) and physical function (tape vs. sham p=0.034; tape vs. control p=0.004). No interactions were found for balance, muscle strength, walking speed or active ROM. CONCLUSION: Wearing kinesio tape for three consecutive days had beneficial effects regarding self reported clinical outcomes of pain, joint stiffness and function. This emphasizes that kinesio taping might be an adequate conservative treatment for the symptoms of knee osteoarthritis. PMID- 29466082 TI - Determination of Optimum Operation Parameters for Low-Intensity Pulsed Ultrasound and Low-Level Laser Based Treatment to Induce Proliferation of Osteoblast and Fibroblast Cells. AB - OBJECTIVE: The aim of this study was to determine the optimum operating parameters (pulse duration, energy levels, and application time) to promote induction of osteoblast and fibroblast cell proliferation and to maintain cell viability treated with low-intensity pulsed ultrasound (LIPUS) and low-level laser therapy (LLLT). BACKGROUND DATA: The positive effects of LIPUS and LLLT on cellular activity have been reported in recent years. Comparisons between experimental parameters of previous studies are difficult because scientific studies reported frequencies and the duty cycles of LIPUS and wavelengths and doses of LLLT in a wide range of parameters. However, optimum amount of energy and optimum time exposure must be determined to induce bone and tissue cell proliferation for effective healing process and to avoid cell damage. MATERIAL AND METHODS: Fibroblast and osteoblast cell cultures were irradiated with LIPUS (10-50% pulse and continuous mode at 1 and 3 MHz for 1, 3, and 5 min) and LLLT (4, 8, and 16 J at 50, 100, 200, 300, 400, and 500 mW). Cell cultures were analyzed using XTT assay. RESULTS: For both cell types, LIPUS treatment with 10% pulse (1:9 duty cycle), 3 MHz, and for 1 min and LLLT treatment over 100 mV for 4, 8, and 16 J modalities contributed to the growth, and may help bone repair and tissue healing process optimally. CONCLUSIONS: Bio-stimulating effects of LLLT irradiation promote proliferation and maintain cell viability better than LIPUS treatment without causing thermal response for both cell types, and the therapeutic modality above 200 mV has maximum effectiveness. PMID- 29466083 TI - Laparoscopic Nissen Fundoplication: An Excellent Treatment of GERD-Related Respiratory Symptoms in Children-Results of a Multicentric Study. AB - INTRODUCTION: Respiratory manifestations of gastroesophageal reflux disease (GERD), particularly chronic cough, are being recognized with increased frequency in children. This survey aimed to investigate the efficacy of laparoscopic Nissen fundoplication for treatment of GERD-related respiratory symptoms not responsive to medical therapy in neurological normal children. MATERIALS AND METHODS: We collected data of children with GERD-related respiratory complaints not responsive to medical therapy who underwent laparoscopic Nissen fundoplication in four European centers of Pediatric Surgery over a 10-year period. We excluded children with neurological impairment. RESULTS: A total of 220 laparoscopic Nissen procedures were performed in the period 2005-2015. Twenty-four (12 boys and 12 girls, average age 9.5 years) out of the 220 patients (10.9%) presented with chronic cough and other respiratory manifestations, including asthma, reactive airway disease, and recurrent pneumonia. Average operative time was 65 minutes (range 45-100). As for postoperative complications, two tight wraps requiring endoscopic dilatation (IIIb Clavien) and two relapses of GERD for slipped Nissen requiring reoperation (IIIb Clavien) were recorded. None of these complications occurred in the group of patients with GERD-related respiratory symptoms. At follow-up evaluation, respiratory symptoms disappeared with a significant improvement of quality of life scoring (I Grade Visick) in 22/24 patients (91.6%). CONCLUSION: Our results confirm that GERD should be investigated as one of the possible etiologic factors in any child with persistent respiratory complaints. In patients with symptoms not responsive to medical therapy, laparoscopic Nissen fundoplication is the treatment of choice with a very high success rate (>90% in our series), a very low morbidity, a significant improvement in airway symptoms, and a marked reduction in the need for medications. PMID- 29466084 TI - Fertility-Related Perceptions and Impact on Romantic Relationships Among Adult Survivors of Childhood Cancer. AB - PURPOSE: To present an overview of fertility-related perceptions and describe the perceived negative/positive impact of (potential) infertility on romantic relationships among childhood cancer survivors. METHODS: Male and female long term childhood cancer survivors (N = 92) aged 22-43 and 7-37 years postdiagnosis, completed an online survey about fertility-related perceptions (i.e., knowledge, beliefs, uncertainty, concern, and attitudes toward testing) and romantic relationships. Potential differences based on sociodemographic/cancer-specific factors were tested. RESULTS: Most survivors (82.4%, n = 75) knew about infertility risk due to childhood cancer treatment. Seventy percent (n = 65) reported being told they were personally at risk, but less than one-third believed it (29.2%, n = 19/65). Half of survivors (48.9%, n = 45) never underwent fertility testing and were unaware of their fertility status. Fertility-related uncertainty and concerns were more common among survivors without children and those who desired (additional) children (d's > 0.5). Among survivors without biological children (n = 52), partnered survivors felt more uncertain about their fertility than singles (d = 0.8). Ten survivors (10.9%) reported a negative impact of infertility on romantic relationships, 6 (6.5%) reported a positive impact, and 7 (7.6%) reported both (e.g., pressure on relationship, fights, break ups, being closer, and open partner communication). CONCLUSIONS: Fertility related perceptions varied among survivors, but the majority never underwent fertility testing. Uncertainty or concerns differed by current circumstances (e.g., wanting children and relationship status). Providers should routinely discuss potential infertility and offer testing throughout survivorship. A negative impact on romantic relationships may seem small, but should be considered for survivors who desire children and may discover they are infertile in the future.

AB - Acute renal failure in the setting of infection with human immunodeficiency virus can be due to various causes including pre-renal causes such as hypotension, sepsis, and nephrotoxic agents; thrombotic microangiopathy; or direct renal parenchymal infections by opportunistic organisms. We present a case of cryptococcal nephritis in a patient with systemic cryptococcosis and discuss the clinical findings as well as the histological, immunofluorescent, and transmission electron microscopy findings in the renal biopsy. PMID- 29466086 TI - Vulnerability of glia and vessels of rat substantia nigra in rotenone Parkinson model. AB - BACKGROUND: Astrocytes have been implicated as potentially exerting both neurotoxic and neuroprotective activities in Parkinson's disease (PD). Whether glial cells negatively impact the neuron integrity remains to be determined. We aimed to assess the vulnerability of glia and vessels in rat substantia nigra in a rotenone PD model. MATERIAL AND METHODS: Twenty adult male albino rats were divided into two equal groups: vehicle-control group (received dimethylsulfoxide + polyethylene glycol (PEG)-300, 1:1 v/v) and rotenone-treated group (received six doses of rotenone, 1.5 mg/kg/48 h s.c.). Using histological, ultrastructural, biochemical, and morphometric techniques, astrocytes, microglia, vessels, and total antioxidant capacity have been assessed. RESULTS: The rotenone-treated group revealed an increase in the number of astrocytes compared to the control, conformational changes of the immature form, disruption of the outer mitochondrial membrane, and no increase in glial filaments. Dark microglia appeared in close vicinity of blood capillaries. The blood capillaries displayed an increase in number compared to the control, degenerated apoptotic endothelium, and pericytes and an increase in string vessels. The total antioxidant level significantly increased in rotenone-treated group (p < 0.001) compared to the control group. CONCLUSION: Our results demonstrated that oxidative stress and mitochondrial dysfunction involved nigral cellular elements other than dopaminergic neurons. These included astrocytes, microglia, vascular endothelial cells, and pericytes, which might result in promoting damage to the neurons. PMID- 29466087 TI - Rat hippocampal CA3 neuronal injury induced by limb ischemia/reperfusion: A possible restorative effect of alpha lipoic acid. AB - Limb ischemia reperfusion (I/R) injury is associated with serious local and systemic effects. Reperfusion may augment tissue injury in excess of that produced by ischemia alone. The hippocampus has been reported to be vulnerable to I/R injury. Alpha lipoic acid (ALA) is an endogenous antioxidant with a powerful antioxidative, anti-inflammatory, and antiapoptotic properties. We studied the probable restorative effect of ALA on limb I/R-induced structural damage of rat hippocampus. Forty adult male albino rats were divided equally into four groups: group I (sham); group II (I/R-1 day) has undergone bilateral femoral arteries occlusion (3 h), then reperfusion for 1 day; group III (I/R-7 days) has undergone reperfusion for seven days; group IV (I/R-ALA) has undergone I/R as group III and received an intraperitoneal injection of ALA (100 mg/kg) for 7 days. I/R groups revealed degenerative changes in the pyramidal neuronal perikarya of CA3 field in the form of dark-stained cytoplasm, dilated RER cisternae, mitochondrial alterations, and dense bodies' accumulation. Their dendrites showed disorganized microtubules. Astrogliosis is featured by an increased number and increased immunoreactivity of astrocytes for glial fibrillary acid protein. Morphometric data revealed significant reduction of light neurons, surface area of neurons, and thickness of the CA3 layer. Most blood capillaries exhibited narrow lumen and irregular basal lamina. ALA ameliorated the neuronal damage. Pyramidal neurons revealed preservation of normal structure. Significant increase in the thickness of pyramidal layer in CA3 field and surface area and number of light neurons was observed but astrogliosis persisted. Limb I/R had a deleterious remote effect on the hippocampus aggravated with longer period of reperfusion. This work may encourage the use of ALA in the critical clinical settings with I/R injury. PMID- 29466088 TI - Crotamine-like from Southern Pacific rattlesnake (Crotalus oreganus helleri) Venom acts on human leukemia (K-562) cell lines and produces ultrastructural changes on mice adrenal gland. AB - Crotamine is a cationic, non-enzymatic, protein integrating a minor family of myotoxins, composed of 42 amino acid residues, described in Viperidae and Crotalidae snake's families that has been used in neuroscience research, drug progressing and molecular diversity reports. Crotamine-like protein (CLP) from C.o.helleri venom was isolated in fraction 5 from 7 peaks obtained by sulfopropyl waters protein pak cationic exchange column. In tricine-SDS-PAGE under non reduced conditions this CLP showed a single band of ~8 kDa molecular weight. CLP induced toxicity of K-562 cells with a CC50 of 11.09 uM. In mice adrenal gland after 24 h of CLP injection, cortical cells exhibited swollen mitochondria with scarce tubular cristae, some elements of smooth and rough endoplasmic reticula, widened nuclear envelope, slightly osmiophilic lipid droplets, and autophagic vacuoles. In some areas cortical cells plasma membrane and endothelial walls disappeared, which indicated a necrosis process. In other areas, endothelial cell cytoplasm did not present the normal caveolae and pinocytotic vesicles. To our knowledge, this is the first report on mice adrenal gland damages, caused by the injection of CLP from rattlesnakes. Our results propose that adrenal cortex lesions may be significant in the envenoming etiopathogenesis by CLP. PMID- 29466089 TI - Photobiomodulation and Cancer: What Is the Truth? AB - BACKGROUND: Photobiomodulation (PBM) therapy is a rapidly growing approach to stimulate healing, reduce pain, increase athletic performance, and improve general wellness. OBJECTIVE: Applying PBM therapy over the site of a tumor has been considered to be a contraindication. However, since another growing use of PBM therapy is to mitigate the side effects of cancer therapy, this short review seeks to critically examine the evidence of whether PBM therapy is beneficial or harmful in cancer patients. MATERIALS AND METHODS: PubMed and Google Scholar were searched. RESULTS: Although there are a few articles suggesting that PBM therapy can be detrimental in animal models of tumors, there are also many articles that suggest the opposite and that light can directly damage the tumor, can potentiate other cancer therapies, and can stimulate the host immune system. Moreover, there are two clinical trials showing increased survival in cancer patients who received PBM therapy. CONCLUSIONS: PBM therapy may have benefits in cancer patients and should be further investigated. PMID- 29466090 TI - Enhanced External Counterpulsation and Short-Term Recovery From High-Intensity Interval Training. AB - PURPOSE: Enhanced external counterpulsation (EECP) is a recovery strategy whose use has increased in recent years owing to the benefits observed in the clinical setting in some cardiovascular diseases (ie, improvement of cardiovascular function). However, its claimed effectiveness for the enhancement of exercise recovery has not been analyzed in athletes. The aim of this study was to determine the effectiveness of EECP on short-term recovery after a fatiguing exercise bout. METHODS: Twelve elite junior triathletes (16 [2] y) participated in this crossover counterbalanced study. After a high-intensity interval training session (6 bouts of 3-min duration at maximal intensity interspersed with 3-min rest periods), participants were assigned to recover during 30 min with EECP (80 mm Hg) or sham (0 mm Hg). Measures of recovery included performance (jump height and mean power during an 8-min time trial), metabolic (blood lactate concentration at several time points), autonomic (heart-rate variability at several time points), and subjective (rating of perceived exertion [RPE] and readiness to compete) outcomes. RESULTS: There were no differences between EECP and sham in mean RPE or power output during the high-intensity interval training session, which elicited a significant performance impairment, vagal withdrawal, and increased blood lactate and RPE in both EECP and sham conditions (all P < .05). No significant differences were found in performance, metabolic, or subjective outcomes between conditions at any time point. A significantly lower high-frequency power (P < .05, effect size = 1.06), a marker of parasympathetic activity, was observed with EECP at the end of the recovery phase. CONCLUSION: EECP did not enhance short-term recovery after a high-intensity interval training session in healthy, highly trained individuals. PMID- 29466091 TI - Infections by Hepatic Trematodes in Cats from Slaughterhouses in Vietnam. AB - Domestic cats are a final host for some hepatic trematodes, and cat meat is used for human consumption in several parts of northern Vietnam. Since there is no tradition for commercial cat rearing in the area, cats are purchased alive from other areas as well, i.e., southern Vietnam and neighboring countries, and brought to slaughterhouses. This uncontrolled trade in live cats could pose a risk for spread of various parasites, including hepatic trematodes. Hence, in this study, we investigated the infections by hepatic trematodes in cats from the slaughterhouses. Cat livers were sampled from 12 slaughterhouses. Clonorchis sinensis and Platynosomum fastosum were found in 14 of 78 necropsied cats of local origin, while more than half of the non-local cats (170 of 318) were infected by C. sinensis, P. fastosum, or Opisthorchis viverrini. The non-local cats had higher prevalence (odds ratio = 6.61, P < 0.01, 95% CI: 2.34-19.41) and intensity of infection (count ratio = 6.47, P < 0.01, 95% CI: 1.77-23.59) by C. sinensis than local cats. Prevalence of P. fastosum infection did not differ significantly between the 2 groups of cats. Opisthorchis viverrini was found at low prevalence (2.5%) in non-local cats. The presence of O. viverrini in cats sampled in northern Vietnam and the high prevalence and intensity of infection in cats of non-local origin suggest that cats are transported over great distances, and this poses a risk of spreading these trematodes. PMID- 29466092 TI - Initial Inoculation Concentration Does Not Affect Final Bacterial Colonization of In vitro Vascular Conduits. AB - BACKGROUND: Despite improved peri-operative care, prosthetic graft infections continue to cause substantial morbidity and mortality. Contemporary graft infection models have tested a conduit's infectability using varying concentrations without standardization. Using a static assay in vitro model, we sought to evaluate the impact of inoculation concentration on vascular conduit attachment. METHODS: The 2-hour and 24-hour attachment of Staphylococcus aureus TCH1516 and Pseudomonas aeruginosa PA01-UW were determined on polytetrafluoroethylene (PTFE), Dacron(r), nitinol, cobalt chromium, and Viabahn(r) (W.L. Gore and Associates, Newark, DE) endoprotheses. Individually and in combination, concentrations at 104, 105, 106, 107, and 108 were tested on 2-mm sections of each graft. After each time interval, the prosthetics were rinsed to remove non-attached bacteria, sonicated to release the attached bacteria, spiral plated, and then analyzed for the attached concentration. RESULTS: After two hours, the higher initial inoculation concentration translated into a higher attachment percentage, but the mean attachment percentage was only 14.8% in the 108 group. Pseudomonas aeruginosa had the greatest mean attachment across all material and concentration groups. The sequence of attachment on the conduits followed a constant order: Dacron, PTFE, cobalt, nitinol, and Viabahn with no difference between Dacron and PTFE. Although there were still differences at the 24-hour mark, the median attachment at each concentration was greater than the highest initial concentration (108). CONCLUSIONS: Initial attachment percentage is poor consistently regardless of inoculation concentration, however, Staphylococcus aureus and Pseudomonas aeruginosa are still able to achieve full attachment after 24 hours. A concentration of less than 107 should be used in vascular graft infection models to ensure adequate bacterial attachment. PMID- 29466093 TI - Efficacy of a Web-Based Tailored Intervention to Reduce Cannabis Use Among Young People Attending Adult Education Centers in Quebec. AB - BACKGROUND: Cannabis use is common among young adults. Web-based interventions are an increasingly popular way to reach this population. The aim of this study was to evaluate the efficacy of a Web-based tailored intervention, developed on theoretical and empirical grounds, to reduce cannabis use among young people by promoting a more positive intention to abstain. METHODS: An experimental design was employed to evaluate the efficacy of the intervention in reducing cannabis use (primary outcome) by bolstering intention (secondary outcome) to abstain from use. Participants were randomly assigned either to an experimental group that received the Web-based tailored intervention or to a control group that did not. RESULTS: Of 588 young adults (18-24 years of age) recruited, 295 were randomly assigned to the experimental group and 293 to the control group. At baseline, 343 reported using cannabis at least once in the past year. An intention-to-treat analysis showed that, at postintervention, a higher proportion of participants in the experimental group had reduced their cannabis use compared with the control group [10.8% vs. 5.1%, chi2(2) = 9.89, p = 0.007]. A mixed model for repeated measures revealed a statistically significant difference in terms of change in intention to abstain from cannabis use in the coming month [Group * Time interaction, F(1,474) = 8.03, p = 0.005]: intention increased for the experimental group (5.07 +/- 2.07 to 5.45 +/- 1.88; p < 0.001), but stayed stable for the control group (5.32 +/- 2.03 to 5.36 +/- 1.99; p = 0.779). CONCLUSION: This study shows that the intervention can be efficacious in reducing cannabis use among young people attending adult education centers. PMID- 29466094 TI - Communication rights: Fundamental human rights for all. AB - The right to communicate includes the right to "freedom of opinion and expression" and rights and freedoms "without distinction of ... language". The 70th anniversary of the Universal Declaration of Human Rights is a time to celebrate and reflect on communication as a human right, particularly with respect to Article 19 and its relationship to national and international conventions, declarations, policies and practices. This review profiles articles from the special issue of International Journal of Speech-Language Pathology (volume 20, issue 1) addressing communication rights from four perspectives: (1) communication rights of all people; (2) communication rights of people with communication disabilities; (3) communication rights of children and (4) communication rights relating to language. Divergent perspectives from across the globe are considered. First-hand accounts of people whose right to communicate is compromised/upheld are included and perspectives are provided from people with expertise and advocacy roles in speech-language pathology, audiology, linguistics, education, media, literature and law, including members of the International Communication Project. Three steps are outlined to support communication rights: acknowledge people - adjust the communication style - take time to listen. Future advocacy for communication rights could be informed by replicating processes used to generate the Yogyakarta Principles. PMID- 29466095 TI - The importance of the human right to communication. PMID- 29466096 TI - Measurement accuracy: Enabling human rights for Fijian students with speech difficulties. AB - PURPOSE: The Universal Declaration of Human Rights enshrines the rights to communication and education and measuring access to these rights for children with disabilities is fundamental. The UNICEF/Washington Group Child Functioning Module (CFM) is being promoted to measure progress against the Sustainable Development Goals for children with disabilities. This cross-sectional diagnostic accuracy study in Fiji compares parent and teacher CFM responses to the Intelligibility in Context Scale for 463 primary-aged students with and without speech difficulties. METHOD: Receiver operating characteristic curves were constructed to analyse CFM accuracy and determine optimal cut-off points; inter rater reliability between teachers and parents was calculated. RESULT: Parent responses to the CFM speech questions achieved an area under the curve of 0.98, indicating "excellent" diagnostic accuracy. Teachers achieved 0.92 ("very good"). The Youden Index identified the optimal cut-off as "some difficulty". CONCLUSION: The CFM appears effective when used by parents or teachers for distinguishing between children with and without speech difficulties. While identified as the optimal cut-off statistically, the "some difficulty" category identifies too many children without speech difficulties to be simplistically applied to funding eligibility. The CFM should be used as a screening tool, followed by further assessment to confirm eligibility. PMID- 29466097 TI - A Clinical Decision Support System for Diabetic Retinopathy Screening: Creating a Clinical Support Application. AB - BACKGROUND: The aim of this study was to build a clinical decision support system (CDSS) in diabetic retinopathy (DR), based on type 2 diabetes mellitus (DM) patients. METHOD: We built a CDSS from a sample of 2,323 patients, divided into a training set of 1,212 patients, and a testing set of 1,111 patients. The CDSS is based on a fuzzy random forest, which is a set of fuzzy decision trees. A fuzzy decision tree is a hierarchical data structure that classifies a patient into several classes to some level, depending on the values that the patient presents in the attributes related to the DR risk factors. Each node of the tree is an attribute, and each branch of the node is related to a possible value of the attribute. The leaves of the tree link the patient to a particular class (DR, no DR). RESULTS: A CDSS was built with 200 trees in the forest and three variables at each node. Accuracy of the CDSS was 80.76%, sensitivity was 80.67%, and specificity was 85.96%. Applied variables were current age, gender, DM duration and treatment, arterial hypertension, body mass index, HbA1c, estimated glomerular filtration rate, and microalbuminuria. DISCUSSION: Some studies concluded that screening every 3 years was cost effective, but did not personalize risk factors. In this study, the random forest test using fuzzy rules permit us to build a personalized CDSS. CONCLUSIONS: We have developed a CDSS that can help in screening diabetic retinopathy programmes, despite our results more testing is essential. PMID- 29466098 TI - Comparing Global Positioning System and Global Navigation Satellite System Measures of Team-Sport Movements. AB - PURPOSE: To compare data from conventional global positioning system (GPS-) and new global navigation satellite system (GNSS-) enabled tracking devices and to examine the interunit reliability of GNSS devices. METHODS: Interdevice differences between 10-Hz GPS and GNSS devices were examined during laps (n = 40) of a simulated game circuit and during elite hockey matches (n = 21); GNSS interunit reliability was also examined during laps of the simulated game circuit. Differences in distance values and measures in 3 velocity categories (low <3 m.s-1; moderate 3-5 m.s-1; and high >5 m.s-1) and acceleration/deceleration counts (>1.46 and <-1.46 m.s-2) were examined using 1 way analysis of variance. Interunit GNSS reliability was examined using the coefficient of variation (CV) and intraclass correlation coefficient. RESULTS: Interdevice differences (P < .05) were found for measures of peak deceleration, low-speed distance, percentage of total distance at low speed, and deceleration count during the simulated game circuit and for all measures except total distance and low-speed distance during hockey matches. Interunit (GNSS) differences (P < .05) were not found. The coefficient of variation was below 5% for total distance, average and peak speeds and distance and percentage of total distance of low-speed running. The GNSS devices had a lower horizontal dilution of precision score than GPS devices in all conditions. CONCLUSIONS: These findings suggest that GNSS devices may be more sensitive than GPS devices in quantifying the physical demands of team-sport movements, but further study into the accuracy of GNSS devices is required. PMID- 29466099 TI - Infrared Laser Improves Collagen Organization in Muscle and Tendon Tissue During the Process of Compensatory Overload. AB - BACKGROUND: The photobiomodulation using the low-level laser therapy (LLLT) exerts a positive modulating effect on the synthesis of collagen in skeletal muscles and tendons. However, few studies have addressed this effect during the compensatory overload. OBJECTIVE: Evaluate the effect of infrared laser on the deposition and organization of collagen fibers in muscle and tendon tissue during compensatory overload of the plantar muscle in rats. MATERIALS AND METHODS: Wistar rats were submitted to bilateral ablation of the synergist muscles of the hind paws and divided in groups: Control, Hypertrophy, and Hypertrophy (H)+LLLT (780 nm, 40 mW, 9.6 J/cm2 and 10 s/point, 8 points, total energy 3.2 J, daily), evaluated at 7 and 14 days. Muscle cuts were stained with Picrosirius-Red and hematoxylin-eosin and tendon cuts were submitted to birefringence for determination of collagen distribution and organization. RESULTS: After 7 days an increase was observed in the area between beam muscles in H+LLLT (25.45% +/- 2.56) in comparison to H (20.3% +/- 3.31), in mature fibers and fibrilis in H+LLLT (29346.88 MUm2 +/- 2182.56; 47602.8 MUm2 +/- 2201.86 respectively) in comparison to H (26656.5 MUm2 +/- 1880.46; 45630.34 MUm2 +/- 2805.82 respectively) and in the collagen area in H+LLLT (2.25% +/- 0.19) in comparison to H (2.0% +/- 0.15). However, after 14 days a reduction was observed in the area between beam muscles in H+LLLT (13.88% +/- 2.54) in comparison to H (19.1% +/- 2.61), in fibrils and mature fibers in H+LLLT (17174.1 MUm2 +/- 2563.82; 32634.04 MUm2 +/- 1689.38 respectively) in comparison to H (55249.86 MUm2 +/- 1992.65; 44318.36 MUm2 +/- 1759.57) and in the collagen area in H+LLLT (1.76% +/- 0.16) in comparison to H (2.09 +/- 0.27). A greater organization of collagen fibers in the tendon was observed after 7 and 14 days in H+LLLT groups. CONCLUSIONS: Infrared laser irradiation induces an improvement in collagen organization in tendons and a reduction in the total area of collagen in muscles during compensatory atrophy following the ablation of synergist muscles.

PMID- 29466103 TI - Migration and Mental Health in Low- and Middle-Income Countries: A Systematic Review. AB - OBJECTIVE: Rural-to-urban migration within low- and middle-income countries (LMICs), and migration from one LMIC to another, are prevalent forms of international migration. Migration may be associated with adverse mental health outcomes. The aim of the current study is to systematically review the literature on migration and mental health between and within LMICs. METHODS: This systematic review of PubMed, PsycINFO, Embase, Web of Science, and PILOTS, identified 2,818 total records published between 1991 and 2016, with 139 of these assessed for eligibility. Two authors reviewed full text to assess if they met inclusion criteria, extracted data, and applied a quality assessment to all included studies. RESULTS: The search identified 37 articles that met the inclusion criteria, based on 28 separate studies. All studies apart from one were cross sectional studies, and studies utilized a range of sampling methods. In all, 19 of these studies were conducted in China. Studies addressed a range of mental health outcomes, and variation in prevalence was reported. Research questions addressed determinants of mental health outcomes, including analysis of risk and protective factors, such as social, cultural, and economic determinants; migration-related risk factors; and substance use. CONCLUSIONS: Limitations in study design and methodological rigor of studies indicate a limited evidence base concerning migration and mental health in LMICs. Expansion of research to different regions, utilization of adapted and validated measurement instruments, and longitudinal research could significantly strengthen the evidence base. PMID- 29466104 TI - Suicidality in High-Risk Psychiatric Patients: The Contribution of Protective Factors. AB - OBJECTIVE: This study's objective was determine the incremental association of reasons for living to the lifetime number of suicide attempts in relation to other known risk and protective factors in a sample of psychiatric patients with extensive psychopathology in residential treatment. METHODS: Participants (n = 131) completed a demographic questionnaire that also asked for information about lifetime suicide history, psychiatric history, trauma, and abuse history. Additional measures of resilience, reasons for living (RFL), and impulsiveness were completed. RESULTS: A history of sexual abuse was associated with an increasing lifetime number of suicide attempts, while a history of physical abuse and trait impulsiveness were not associated with the lifetime number of suicide attempts. Survival and coping beliefs, a subscale of the Reasons for Living Inventory (RFLI), was found to add incremental predictive validity to the number of lifetime suicide attempts. A composite fear variable, combining fear of suicide and fear of social consequences of suicide, was negatively correlated with lifetime number of attempts but did not add incremental validity to the prediction of lifetime number of suicide attempts. CONCLUSION: In a sample of participants with significant psychiatric impairment, the protective factor of survival and coping beliefs may be an important barrier to repeated suicide attempts and may be considered a suicide-specific resilience measure. Understanding the psychological processes contributing to the development of such protective factors as resilience, meaning in life, and coping resources is an important area of study and a potential avenue for targeted therapeutic intervention in high-risk populations.

PMID- 29466107 TI - A Randomized Controlled Trial of the Collaborative Assessment and Management of Suicidality versus Enhanced Care as Usual With Suicidal Soldiers. AB - OBJECTIVE: This study describes a randomized controlled trial called "Operation Worth Living" (OWL) which compared the use of the Collaborative Assessment and Management of Suicidality (CAMS) to enhanced care as usual (E-CAU). We hypothesized that CAMS would be more effective than E-CAU for reducing suicidal ideation (SI) and suicide attempts (SA), along with secondary behavioral health and health care utilization markers for U.S. Army Soldier outpatients with significant SI (i.e., > 13 on Beck's Scale for Suicide Ideation). METHOD: Study participants were 148 Soldiers who presented to a military outpatient behavioral health clinic. There were 73 Soldiers in the experimental arm of the trial who received adherent CAMS; 75 Soldiers received E-CAU. Nine a-priori treatment outcomes (SI, past year SA, suicide-related emergency department (ED) admits, behavioral health-related ED admits, suicide-related inpatient psychiatric unit (IPU) days, behavioral health-related IPU days, mental health, psychiatric distress, resiliency) were measured through assessments at Baseline and at 1, 3, 6, and 12 months post-Baseline (with a 78% retention of intent-to-treat participants at 12 months). RESULTS: Soldiers in both arms of the trial responded to study treatments in terms of all primary and secondary outcomes (effect sizes ranged from 0.63 to 12.04). CAMS participants were significantly less likely to have any suicidal thoughts by 3 months in comparison to those in E-CAU (Cohen's d = 0.93, p=.028). CONCLUSIONS: Soldiers receiving CAMS and E-CAU significantly improved post-treatment. Those who received CAMS were less likely to report SI at 3 months; further group differences were not otherwise seen. PMID- 29466108 TI - Uncertainty as a Driver of Mental Disorder Diagnostic Strategies. PMID- 29466109 TI - Uncertainty Theory: A Powerful Approach to Understanding Psychiatric Disorder. AB - OBJECTIVE: The tendency over the years in the mental health field has been to cling in circular fashion to one single domain after another, biological, psychological, or social, to explain severe disorder and not even to consider the data from the domain of focus that came before. This report notes that attempts to explore more complex biopsychosocial explanations that integrate the diverse domains have been generally ignored or foundered on the problems posed by the complexities involved and suggests an approach for moving beyond these problems. METHOD: A case history using two different formats highlights the degree to which the single domain models ignore one or another area of data. RESULTS: Uncertainty theory is suggested as providing an important basis for exploring the complexities of a biopsychosocial understanding of mental health problems. CONCLUSIONS: This approach can provide a possible orientation to promote improved research, training, and treatment. PMID- 29466110 TI - Peritraumatic Reaction Courses During War in Individuals With Serious Mental Illness: Gender, Mental Health Status, and Exposure. AB - OBJECTIVE: We assessed in vivo symptom courses of early psychological responses during war and investigated the influence of exposure, gender, and a prior diagnosis of severe mental illness (SMI). METHOD: Participants were 181 highly exposed individuals from the general population and community psychiatric rehabilitation centers. A 30-day twice-daily Internet-smartphone-based intensive assessment two weeks into the 2014 Israel-Gaza war estimated peritraumatic symptom clusters, sense of threat, negative emotions and cognitions, and siren exposure during two periods that varied in exposure level. Piecewise growth curve modeling procedures were performed. RESULTS: We found different courses for most variables, gender, and SMI status. Women were more reactive two weeks into the war but reduced their reactivity level at a faster pace than males, reaching lower symptom levels one month later. Women's courses were characterized by arousal, negative emotionality, sense of threat, and reactivity to siren exposure. No-SMI men had a stable course followed by a significant reduction in arousal, negative emotions, avoidance, and perceived threat during a "return to routine" lower-level intensity period of the war. Individuals with SMI had higher reactivity levels at study onset; but while women with SMI improved over time, men with SMI worsened. SMI reactivity was characterized by negative cognitions, intrusions, and avoidance. CONCLUSIONS: Early reactions during prolonged exposure to war are variable, dynamic, and affected by exposure context. Symptoms, emotions, and cognitions develop differentially over time and are affected by gender and mental health status. The identification of various early stress courses should inform primary intervention strategies. PMID- 29466112 TI - On the Illusion of Certainty. PMID- 29466111 TI - Facilitating Fear-Based Memory Extinction With Dexamethasone: A Randomized Controlled Trial in Male Veterans With Combat-Related PTSD. AB - OBJECTIVE: Animal and preliminary human studies have demonstrated that glucocorticoids enhance the extinction of fear memories. Impaired extinction of fear memories is a critical component in the development and maintenance of posttraumatic stress disorder (PTSD). The purpose of this translational study was to determine the effectiveness of pairing a glucocorticoid with trauma memory reactivation as a novel intervention to treat PTSD and to measure the duration of the effect. METHOD: A total of 54 male veterans with combat-related PTSD in this double-blind, randomized, placebo-controlled trial received either four weekly glucocorticoid (dexamethasone [DEX]) or placebo administrations paired with a 45 second trauma memory reactivation task. PTSD and depressive symptom severity were assessed at baseline and at one three, and six months. RESULTS: Trauma memory activation paired with DEX versus trauma memory activation paired with placebo demonstrated a significantly greater reduction of PTSD symptoms for DEX at the one-month (p = .037) and three-month (p = .036) posttreatment assessments, but the difference was no longer evident at six months. DEX showed a nonsignificantly greater reduction of PTSD symptoms than placebo over the course of the study (p = .067). Significantly more veterans in the DEX group lost their diagnosis of PTSD at one month posttreatment compared to the placebo group, but the difference was not maintained at three or six months. DEX had no effect on depression symptoms. CONCLUSIONS: Despite insufficient power to test differences in PTSD symptom reduction, findings suggest that this novel intervention may have potential for treatment of combat-related PTSD.

AB - Childhood maltreatment is associated with risk for suicidal ideation later in life, yet more research is needed on the indirect effects and bioregulatory protective factors in this association. The present study aimed to investigate the indirect influence of childhood maltreatment on suicidal ideation in emerging adulthood via level of self-esteem, and examine the moderating role of heart rate variability (HRV; a proxy for emotion regulation) in this indirect association. The study included a sample of 167 non-metropolitan emerging adults (Mage = 21.17, 55.8% female) of low-socioeconomic status (low-SES). HRV data were obained using an electrocardigram, whereas childhood maltreatment, suicidal ideation, and self-esteem data were obtained via self-report. Childhood maltreatment was indirectly associated with suicidal ideation via reduced self-esteem. HRV buffered this indirect association. Childhood maltreatment poses a risk for the development of suicidal ideation. Interventions that bolster self-esteem and emotion regulation may reduce suicide risk for emerging adults with a history of childhood maltreatment. PMID- 29466116 TI - Acute Effects of Low-Level Laser Therapy on Patients' Functional Capacity in the Postoperative Period of Coronary Artery Bypass Graft Surgery: A Randomized, Crossover, Placebo-Controlled Trial. AB - OBJECTIVE: The aim of this study was to evaluate the acute effects of low-level laser therapy (LLLT) on the functional capacity to exercise tested by incremental shuttle walking test (ISWT) after coronary artery bypass graft (CABG) surgery. METHODS: Fifteen male patients (60 +/- 9 years) were crossed over during the experiment, to compare the outcomes after active LLLT and placebo LLLT treatments. LLLT (850 nm, 200 mW, 30 J to each point, resulting in a total of 240 J per quadriceps muscle), using a multidiode cluster (five spots; 6 J/spot) in eight points per leg was performed 3 min before the ISWT. We analyzed distance walked, Borg scale of perceived exertion, heart rate, and brachial arterial blood pressure. Markers of tissue damage [lactate dehydrogenase (LDH)] and oxidative stress [lipid peroxidation, total thiol levels, and antioxidant enzyme activity of superoxide dismutase (SOD) and catalase (CAT)] were also measured in peripheral blood. RESULTS: Comparison of the distances walked revealed no significant differences between the LLLT and placebo LLLT groups (p = 0.779). Regarding the Borg scale (p = 0.567), heart rate (p = 0.506) as well as systolic and diastolic blood pressure (p = 0.164 and p = 0.140, respectively), no differences were observed between LLLT and placebo LLLT groups. Application of LLLT was not able to change levels of LDH (p = 0.214), oxidative lipid damage (p = 0.733), total thiol levels (p = 0.925), SOD (p = 0.202), and CAT (p = 0.825) enzyme activities. CONCLUSIONS: Acute LLLT improved neither functional capacity to exercise nor the markers of oxidation after CABG. TRIAL REGISTRATION: Registered as a clinical trial (NCT02688426). PMID- 29466118 TI - Effectiveness of a Radiographic Anatomy Software Application for Enhancing Learning of Veterinary Radiographic Anatomy. AB - The goal of this study was to determine the effectiveness of an interactive radiology software application that we developed to enhance learning of normal canine radiographic anatomy. All first-year veterinary medical students were eligible to participate in this subject pre-test-post-test experimental design. When presented with the software application, all students had completed two terms of gross anatomy in which the complete anatomy of the dog had been taught using a combination of lectures and laboratory dissections, including radiographic examples. The software application was divided into four body regions: front limb, hind limb, skull/spine, and thorax/abdomen, each with a learning mode and a quiz mode. Quizzes were composed of 15 questions drawn pseudo randomly without repeat from all structures within a region (median 206 structures). Students were initially given the software application with only the quiz mode activated. After completing four quizzes, one for each body region, students were given access to the software application with both learning mode and quiz mode activated. Students were instructed to spend 30 minutes using the learning mode to study the radiographic anatomy of each region and to retake each quiz. Quiz scores after using the learning mode were significantly higher for each body region (p<.001), with a large effect size for all four regions (Cohen's d=0.83-1.56). These results suggest that this radiographic anatomy software application is an effective tool for students to use to learn normal radiographic anatomy.

AB - INTRODUCTION: Nissen fundoplication is frequently applied in the surgical treatment of patients with gastroesophageal reflux disease (GERD). When the gastroesophageal junction remains too large or becomes too narrow, persistent GERD or dysphagia may occur. To assure a correct size of the gastroesophageal junction, the fundoplication can be created over a bougie. However, this increases the risk of esophageal perforation. Therefore, we have modified a previously described technique to create a standardized fundoplication without the use of a bougie. In this article, we describe this technique and demonstrate the initial results. MATERIALS AND METHODS: We describe a technique to create a standardized Nissen fundoplication. After suture repair of the hiatal hernia, three marking sutures were placed on the gastric fundus, based on an equilateral triangle. The size of this triangle determines the final diameter of the fundoplication. With these measurements, we assure sufficient patency, minimize rotation, and create a more reproducible fundoplication that may reduce postoperative dysphagia. RESULTS: We have operated 15 patients according to this technique. Mean operative time was 69.5 (SD 8.4) minutes, no complications occurred. There was no early dysphagia and the mean length of stay was 1.3 days (1-2). Quality of life after 1 year was excellent. CONCLUSIONS: This modified method for standardized Nissen fundoplication is safe and might reduce postoperative dysphagia. Quality of life after 1 year is excellent. The effect on postoperative dysphagia and the reproducibility of this technique should be established in a large prospective study.

AB - Various U.S. laws, such as the Clean Air Act and the Food Quality Protection Act, require additional protections for susceptible subpopulations who face greater environmental health risks. The main ethical rationale for providing these protections is to ensure that environmental health risks are distributed fairly. In this article, we (1) consider how several influential theories of justice deal with issues related to the distribution of environmental health risks; (2) show that these theories often fail to provide specific guidance concerning policy choices; and (3) argue that an approach to public decision making known as accountability for reasonableness can complement theories of justice in establishing acceptable environmental health risks for the general population and susceptible subpopulations. Since accountability for reasonableness focuses on the fairness of the decision-making process, not the outcome, it does not guarantee that susceptible subpopulations will receive a maximum level of protection, regardless of costs or other morally relevant considerations.

AB - Inclusion of children in medical decision making, to the extent of their ability and interest in doing so, should be the default position, ensuring that children are routinely given a voice. However, optimizing the involvement of children in their health care decisions remains challenging for clinicians. Missing from the literature is a stepwise approach to assessing when and how a child should be included in medical decision making. We propose a systematic approach for doing so, and we apply this approach in a discussion of two challenging clinical cases. The approach is informed by a literature review, and is anchored by case studies of teenagers' refusal of clinical care, regulatory requirements for research assent, and the accepted approach to involving cognitively impaired adults in medical decisions.

AB - To evaluate the value of ultrasonography in the diagnosis of anterior cruciate ligament injury (ACL injury) by conducting a systematic review and meta-analysis. A literature search was carried out in the Cochrane Library, Embase, Pubmed databases and included studies prior to April 2017. Based on inclusion and exclusion criteria, studies evaluating ultrasound to diagnose ACL injury were selected. MRI, arthroscopy and clinical-follow were considered the reference standards. The diagnostic accuracy of ultrasound was assessed using a combination of sensitivity, specificity, likelihood ratio (LR), post-test probability, diagnostic odds ratio (DOR) and by summarizing the area under the receiver operating characteristic (SROC) curve. A total of 4 studies involving 246 patients were eventually included in the analysis. In these four studies, the combined sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, post-test probability and DOR were 90.0% (95% CI: 77-96), 97% (95% CI: 90 99), 31.08 (95% CI: 8.75-110.41), 0.11 (95% CI: 0.05-0.24), 89% (3%) and 288.81 (95% CI: 78.51-1062.48), respectively. The area under the SROC curve was 0.98 (95% CI: 0.97-0.99). Our meta-analysis showed that ultrasound can play an important role in the diagnosis of ACL injury. Because of its high sensitivity, high specificity and high diagnostic ability, ultrasound should be a part of the standard diagnostic work-up of an ACL injury. PMID- 29466146 TI - Pleural Disease.

AB - BACKGROUND: Fusions involving one of three tropomyosin receptor kinases (TRK) occur in diverse cancers in children and adults. We evaluated the efficacy and safety of larotrectinib, a highly selective TRK inhibitor, in adults and children who had tumors with these fusions. METHODS: We enrolled patients with consecutively and prospectively identified TRK fusion-positive cancers, detected by molecular profiling as routinely performed at each site, into one of three protocols: a phase 1 study involving adults, a phase 1-2 study involving children, or a phase 2 study involving adolescents and adults. The primary end point for the combined analysis was the overall response rate according to independent review. Secondary end points included duration of response, progression-free survival, and safety. RESULTS: A total of 55 patients, ranging in age from 4 months to 76 years, were enrolled and treated. Patients had 17 unique TRK fusion-positive tumor types. The overall response rate was 75% (95% confidence interval [CI], 61 to 85) according to independent review and 80% (95% CI, 67 to 90) according to investigator assessment. At 1 year, 71% of the responses were ongoing and 55% of the patients remained progression-free. The median duration of response and progression-free survival had not been reached. At a median follow-up of 9.4 months, 86% of the patients with a response (38 of 44 patients) were continuing treatment or had undergone surgery that was intended to be curative. Adverse events were predominantly of grade 1, and no adverse event of grade 3 or 4 that was considered by the investigators to be related to larotrectinib occurred in more than 5% of patients. No patient discontinued larotrectinib owing to drug-related adverse events. CONCLUSIONS: Larotrectinib had marked and durable antitumor activity in patients with TRK fusion-positive cancer, regardless of the age of the patient or of the tumor type.

PMID- 29466159 TI - Aspirin or Rivaroxaban for VTE Prophylaxis after Hip or Knee Arthroplasty. AB - BACKGROUND: Clinical trials and meta-analyses have suggested that aspirin may be effective for the prevention of venous thromboembolism (proximal deep-vein thrombosis or pulmonary embolism) after total hip or total knee arthroplasty, but comparisons with direct oral anticoagulants are lacking for prophylaxis beyond hospital discharge. METHODS: We performed a multicenter, double-blind, randomized, controlled trial involving patients who were undergoing total hip or knee arthroplasty. All the patients received once-daily oral rivaroxaban (10 mg) until postoperative day 5 and then were randomly assigned to continue rivaroxaban or switch to aspirin (81 mg daily) for an additional 9 days after total knee arthroplasty or for 30 days after total hip arthroplasty. Patients were followed for 90 days for symptomatic venous thromboembolism (the primary effectiveness outcome) and bleeding complications, including major or clinically relevant nonmajor bleeding (the primary safety outcome). RESULTS: A total of 3424 patients (1804 undergoing total hip arthroplasty and 1620 undergoing total knee arthroplasty) were enrolled in the trial. Venous thromboembolism occurred in 11 of 1707 patients (0.64%) in the aspirin group and in 12 of 1717 patients (0.70%) in the rivaroxaban group (difference, 0.06 percentage points; 95% confidence interval [CI], -0.55 to 0.66; P<0.001 for noninferiority and P=0.84 for superiority). Major bleeding complications occurred in 8 patients (0.47%) in the aspirin group and in 5 (0.29%) in the rivaroxaban group (difference, 0.18 percentage points; 95% CI, -0.65 to 0.29; P=0.42). Clinically important bleeding occurred in 22 patients (1.29%) in the aspirin group and in 17 (0.99%) in the rivaroxaban group (difference, 0.30 percentage points; 95% CI, -1.07 to 0.47; P=0.43). CONCLUSIONS: Among patients who received 5 days of rivaroxaban prophylaxis after total hip or total knee arthroplasty, extended prophylaxis with aspirin was not significantly different from rivaroxaban in the prevention of symptomatic venous thromboembolism.

AB - OBJECTIVE: to compare strategies of invasive treatment of patients with non-ST elevation acute coronary syndrome (NSTEACS) hospitalized in 2014 and 2015. MATERIALS AND METHODS: We have analyzed treatment strategy used in patients with NSTEACS hospitalized in cardio-reanimation department of a city hospital during one month in two successive years (January 2014 and November 2015). We have compared indications to, and timing of coronary angiography, numbers of performed percutaneous coronary interventions (PCI) and coronary artery bypass grafting surgeries. RESULTS: Portion of patients subjected to invasive procedures in 2014 was 26 %, in 2015-42 %. All 32 primary procedures were PCIs. An increase was due to delayed interventions (24-72 hours), which were not performed in 2014. We also more often used selective multivessel coronary stenting, what facilitated availability of invasive treatment for elderly patients. Hospital mortality of patients with NSTEACS decreased from 16 to 7 %. PMID- 29466164 TI - Human Neonatal Rotavirus Vaccine (RV3-BB) to Target Rotavirus from Birth. AB - BACKGROUND: A strategy of administering a neonatal rotavirus vaccine at birth to target early prevention of rotavirus gastroenteritis may address some of the barriers to global implementation of a rotavirus vaccine. METHODS: We conducted a randomized, double-blind, placebo-controlled trial in Indonesia to evaluate the efficacy of an oral human neonatal rotavirus vaccine (RV3-BB) in preventing rotavirus gastroenteritis. Healthy newborns received three doses of RV3-BB, administered according to a neonatal schedule (0 to 5 days, 8 weeks, and 14 weeks of age) or an infant schedule (8 weeks, 14 weeks, and 18 weeks of age), or placebo. The primary analysis was conducted in the per-protocol population, which included only participants who received all four doses of vaccine or placebo within the visit windows, with secondary analyses performed in the intention-to treat population, which included all participants who underwent randomization. RESULTS: Among the 1513 participants in the per-protocol population, severe rotavirus gastroenteritis occurred up to the age of 18 months in 5.6% of the participants in the placebo group (28 of 504 babies), in 1.4% in the neonatal schedule vaccine group (7 of 498), and in 2.7% in the infant-schedule vaccine group (14 of 511). This resulted in a vaccine efficacy of 75% (95% confidence interval [CI], 44 to 91) in the neonatal-schedule group (P<0.001), 51% (95% CI, 7 to 76) in the infant-schedule group (P=0.03), and 63% (95% CI, 34 to 80) in the neonatal-schedule and infant-schedule groups combined (combined vaccine group) (P<0.001). Similar results were observed in the intention-to-treat analysis (1649 participants); the vaccine efficacy was 68% (95% CI, 35 to 86) in the neonatal schedule group (P=0.001), 52% (95% CI, 11 to 76) in the infant-schedule group (P=0.02), and 60% (95% CI, 31 to 76) in the combined vaccine group (P<0.001). Vaccine response, as evidenced by serum immune response or shedding of RV3-BB in the stool, occurred in 78 of 83 participants (94%) in the neonatal-schedule group and in 83 of 84 participants (99%) in the infant-schedule group. The incidence of adverse events was similar across the groups. No episodes of intussusception occurred within the 21-day risk period after administration of any dose of vaccine or placebo, and one episode of intussusception occurred 114 days after the third dose of vaccine in the infant-schedule group. CONCLUSIONS: RV3-BB was efficacious in preventing severe rotavirus gastroenteritis when administered according to a neonatal or an infant schedule in Indonesia.

PMID- 29466167 TI - [Lung Hyperinflation in Chronic Obstructive Pulmonary Disease and Long-Term Outcomes of Percutaneous Coronary Intervention]. AB - OBJECTIVE: to assess the effect of lung hyperinflation (LHI) in patients with chronic obstructive pulmonary disease (COPD) on longterm outcomes of percutaneous coronary intervention (PCI). MATERIALS AND METHODS: Patients with COPD who suffered stable ischemic heart disease and underwent PCI (n=135) were included in a prospective cohort study. LHI was found in 60 patients, while 75 patients had no LHI. Evaluation included comparing the frequency of major adverse cardiac events (MACE) (cardiac death, myocardial infarcpunktion [MI], stroke, repeat revascularization) and Kaplan-Mayer curves between groups of patients with and without LHI. Associations of parameters of pulmonary function and plasma levels of high sensitivity C-reactive protein (hsCRP) with occurrence of MACE were also elucidated. Duration of follow-up was up to 3 years (median 20 months). RESULTS: Study groups did not differ significantly by main factors of cardiovascular risk, except plasma level of hsCRP. MACE occurred in 41.7 and 26.7 % of patients in groups with and without LHI, respectively (p=0.097). However, divergence of the Kaplan-Meier curves was statistically significant (p=0.04). The main contribution was made by cardiac death, MI and stroke (21.7 and 8.0 % among patients with and without LHI; p=0.027). No difference was found regarding repeat revascularization. The correlation between functional residual lung capacity and plasma level of hsCRP was closer than the correlation between forced expiratory volume in 1 second and hsCRP level (r=0.36 and r=0.19; p.

AB - : Aim of the study was assessment of efficiency of lung ventilation and its relationship with quality of life in patients undergoing orthotopic heart transplantation (OHT). MATERIALS AND METHODS: The study involved 40 patients with terminal chronic heart failure (CHF) included in the waiting list for heart transplantation. Before surgery and after OHT all patients underwent cardiopulmonary exercise testing, evaluation of clinical status and quality of life (QL) according to the 36-Item Short Form Survey (SF-36). RESULTS: During the follow-up period (5 years) after OHT there were a significant increase in physical capacity, two-fold increase of peak oxygen consumption (VO2), normalization of VE/VCO2 slope level, improvement of the efficiency of the VO2 recovery within first minute and reduction of the VO2 recovery time. OHT was associated with significant improvement of physical and mental health components of QL. Among exercise test parameters significantly associated with improved physical health component of QL were increments in exercise capacity, peak VO2, rate of VO2 recovery within first minute. There was no relationship between cardiopulmonary parameters of exercise test and mental health component of QL. CONCLUSION: In patients with terminal CHF OHR led to significant increase of the lung ventilation efficiency and QL. Factors contributing to QL improvement after OHT were augmentation of left ventricular ejection fraction and reduction of CHF NYHA class. Among cardiopulmonary exercise test parameters, a high predictive value relative to improvement of subjective assessment of physical health component of QL showed exercise capacity, peak VO2, and efficiency of VO2 recovery within first minute.

AB - PURPOSE: to study efficacy of various schemes of therapy of patients with chronic heart failure (CHF) and anemia. MATERIALS AND METHODS: We included in this study 208 patients with CHF of ishemic etiology (mean age 60.6+/-1.4 years, 174 with and 34 without anemia). According to therapeutic regimen of the use of methoxy polyethylene glycol-epoetin beta (MEB, 0.60 msg/kg) and intravenous (IV) iron hydroxide sucrose complex all patients were divided into 4 groups. In all patients before and after treatment we determined Hb, Ht, plasma levels of ferritin, erythropoietin (EPO), NT-proBNP, IL-1, IL-6, TNF-alpha, transferrin saturation (TS), total vascular peripheral resistance, and parameters of systolic and diastolic function of left ventricular (LV) myocardium (by echocardiography and doppler echocardiography). RESULTS: In patients with NYHA class I-IV CHF and anemia increases of Hb, Ht, TS, levels of EPO and ferritin occurred during treatment by basic drugs combained with MEB. In subgroups of patients with NYHA class I-II and III-IV the 6-minute walk distance significantly increased by 25.1 and 38.3%, and GFR- by 24.5 and 14.9%, respectively. At the background of therapy with IV iron we observed significant increases of Hb, plasma level of ferritin, and TS. Combined treatment with MEB and IV iron was associated with positive dynamics of Hb, Ht, levels of ferritin, EPO, NT-proBNP, and IL-6. In this group in subgroups of patients with NYHA class I-II and III-IV the 6-minute walk distance significantly increased by 21.6 (p.

AB - OBJECTIVE: to examine relationship between anatomical changes of the left ventricle (LV), dynamics of velocity of its volume modification, and blood flows in the LV in patients with mitral regurgitation (MR) before and after surgical treatment. MATERIALS AND METHODS: We included into this study 58 patients with severe 3-4 degree MR (38 men, 20 women aged 24-69 [mean age 51+/-9] years) in sinus rhythm (96 %) or atrial fibrillation (4 %). The control group included 86 healthy volunteers, mean age 39+/-7 years. Transthoracic echocardiographic studies were performed in both groups by standard technique at rest using a high quality echocardiograph Vivid E9, equipped with a 3.5-4.6 MHz multi frequency transducer (in patients before and after surgical repair - mitral valve [MV] replacement and MV reconstruction with annuloplasty ring). The analysis of files recorded was performed off-line by vector analysis technique including estimation of myocardial deformation velocities and dynamics of LV volume modification, construction of "flow-volume" diagram, calculation of the expended kinetic energy, and registration of intraventricular blood flows. RESULTS: End diastolic volume (EDV), end systolic volume (ESV) and total stroke volume (TSV) (effective + retrograde) were significantly increased in patients with severe LV volume overload before surgery in comparison with the control group (p.

This article provides a brief overview of recent data that relate to microRNA expression in various cardiovascular diseases. Detecting significant changes in the level of expression of these molecules in various diseases means that microRNAs can be considered to be potential biomarkers of human pathologies including heart failure. Studying the relationship between the mechanisms of cardiovascular disease and the level of expression of a variety of microRNAs, as well as establishing their exact relationships with the genes is an urgent problem and requires further research. PMID- 29466174 TI - [Pharmacological Properties of Loop Diuretics and Their Clinical Effects]. AB - Edematous states caused by an excessesive extracellular fluid retention are major components of cardiovascular and renal disorders including chronic kidney disease, nephrotic syndrome, and heart failure. The use of diuretic drugs from various groups including loop duiretics are important means of pharmacological correction of these clinical conditions. Moreover, diuretics used to lower bood pressure as a part of antihypertensive treatment, reduce cardiovascular events. The response of patients to the dose of a diuretic is reflected by a sigmoid dose response curve which can be affected by changes of sodium content in the body. Loop diuretics may fail to control salt and water retention despite the use of appropriate doses. The main reasons for loop diuretic resistance may be determined by further reduction of glomerular filtration rate and reduced peak concentration of loop diuretics in primary urine. Chronic treatment with loop diuretics can cause compensatory hyperthrophy of epithelial cells along the ascending limb of the loop of Henle and thus decrease of its diuretic effect. The principles of avoiding this phenomenon are the restriction of sodium intake, correction of doses, timing and frequency of drug administration, and use of combination diuretic therapy. Loop diuretic - related adverse events that involve uricaemia and ototoxicity also should be taken into consideration. PMID- 29466175 TI - [Giant Aneurysms in Coronary Arteries of a Young Woman]. AB - Coronary arteries aneurysms with their thrombotic occlusion are known to be detected in young patients who have suffered Kawasaki disease in childhood. The other vascular beds are usually not involved. In the literature one can find not enough information regarding diagnostics of this pathology, as well as no specific treatment algorithm. We present here a clinical case of re-emergence of giant aneurysms of coronary arteries in the young female patient with subsequent immuno-histological confirmation of previous Kawasaki disease.

PMID- 29466177 TI - [Anticoagulant therapy and prognosis in patients with CHF and AF in the setting of real-life clinical practice]. AB - BACKGROUND: Prevalence of atrial fibrillation (AF) grows with the increase in CHF FC and reaches 45% in III-IV FC CHF. With an adequate anticoagulant (AC) therapy, the risk of thromboembolic complications does not significantly differ between patients with I-II FC and III-IV FC CHF. Of particular interest is studying administration of the anticoagulant treatment and correspondence between the SAMe TT2R2 scale and actual TTR values in patients with CHF and AF in real-life clinical practice. AIM: Toanalyze the efficacy of anticoagulant therapy and prognosis in patients with CHF and AF in the setting of real-life clinical practice. MATERIALS AND METHODS: The study included 272 patients with CHF and AF who were discharged from the hospital where they had been treated for decompensated CHF and who were followed up as outpatients for a year. Efficacy of the AC therapy was evaluated; parameters of CHA2DS2-VASc, HAS-BLED, and SAMe TT2R2 scales were calculated at baseline. TTR was computed to determine the maintenance time. RESULTS: Patients with CHF had permanent (56.3%), persistent (38.6%), or paroxysmal (5.1%) AF. The mean CHA2DS2-VASc score was 3.83+/-1.16 and the mean HAS-BLED score was 1.3+/-0.83. SAMe-TT2R2 scores were 0 for 1.6% of patients; 1 for 36.9%, and 2< for 61.5%. At baseline, one third of patients with CHF and AF received antiplatelet therapy (APT) and every forth patient received no therapy. At one year, 69.0% of patients took AC on a constant basis (r.

AB - AIM: To determine a possibility for improving the capability of patients with chronic heart failure (CHF) for self-care and self-control using a remote monitoring platform on a basis of mobile application. MATERIALS AND METHODS: The study included 142 patients with CHF of different etiology. During the stay in hospital, patients attended structured classes on different aspects of self control and self-care in CHF. The group of active management consisted of 47 patients who subsequently used a version of mobile application. The control group consisted of 95 patients with CHF. The remote monitoring platform was based on a translated to Russian version of the European Heart Failure Self-Care Behavior Scale (EHFScBS_9), which included 9 items addressing different issues of selfcontrol. Responses were presented as a scale ranging from "completely agree" (1) to "completely disagree (5). The total score was calculated by adding scores for each item. The lower the score the better was the capability of CHF patients for self-care. The followup duration was 6 months. RESULTS: On admission, the mean EHFScBS_9 score decreased to 15+/-2.3 in the mobile application group whereas in the control group, the mean score was 23.95+/-3.02, which indicated a significantly better capability for self-care in the mobile application group (p. PMID- 29466179 TI - [Characteristics and treatment of hospitalized patients with CHF]. AB - The article analyzes some characteristics of hospitalized patients with decompensated chronic heart failure (HF) according to data from Russian and international registries, management of decompensated HF, and tactics for titration of evidence-based disease-modified therapies. The demographic characteristics of the patients from the registers that were used for the research are similar. Yet, the proportion of HF patients with preserved LVEF was greater according to data from several Russian studies. Meanwhile, with the patients that did not receive any loop diuretics and therefore had apparently no congestion signs being excluded from the analysis, the proportion of HF patients with preserved LVEF became similar to that from the international studies. The registers also showed that pulmonary edema and acute left ventricular failure were observed in less than a half of the cases. Nevertheless, patients with mild congestion symptoms still have bad lingering prognosis and require the same amount of medical attention. Up to 40 % of admissions for decompensated CHF resulted from a dietary disorder (excessive sodium consumption), low compliance with therapy and lack of access to primary care providers. Furthermore, the analysis of the outpatient treatment administered prior to the forthcoming hospitalization showed a low prescription rate of evidence-based disease modifying therapies (ACEi or ARNi, BB, MRA). It is emphasized that in part of patients the administration and/or titration of this therapy can be started during hospitalization. The article also discusses the use of a new class of drugs, angiotensin receptor-neprilysin inhibitors (ARNi), including not only transferring patients from ACEi to ARNi but also the possibility of administering ARNi to stable, hospitalized patients who do not require intravenous diuretics and inotropic drugs. PMID- 29466180 TI - [Possibilities of modern echocardiographic technologies in the early diagnosis of the cardiotoxic effect of chemotherapy drugs anthracycline series in cancer patients]. AB - Chronic heart failure following chemotherapy for cancer is a relevant issue of an adverse cardiovascular prognosis and premature death in cancer patients. This category of patients requires thorough and chronic monitoring of the cardiovascular system, prevention and treatment of cardiovascular complications of chemotherapy, such as IHD, systolic or diastolic myocardial dysfunction, arterial or pulmonary hypertension, pulmonary thromboembolism, pericarditis, stroke, and peripheral vascular disease. However, many aspects of this important interdisciplinary issue presently remain understudied. For instance, it is still impossible to predict long-term consequences of chemotherapy for cancer and development of the associated cardiovascular complications listed above. Baseline evaluation of the risk for cardiovascular complications is a major component in management of such patients. High-risk patients need an individual, detailed schedule of cardiovascular treatment throughout and after the course of chemotherapy. Furthermore, early detection of subclinical myocardial dysfunction is critical for prevention of the most threatening cardiovascular complications of chemotherapy, CHF. Detecting impaired LV EF following chemotherapy is, unfortunately, only a late predictor of irreversible changes, such as toxic cardiomyopathy and clinically pronounced, rapidly progressing CHF. Markers of myocardial injury, high-sensitivity troponins and natriuretic peptides, in combination with up-to-date EchoCG technologies have been recently used. Their use, for instance, for evaluation of LV myocardial global longitudinal strain to detect early, reversible changes in structure and mechanics of the myocardium is promising for ultimate improvement of prediction for such patients.

AB - Patients with coronary heart disease (CHD) and abdominal obesity (AO) are a priority group for the most active implementation of secondary prevention efforts. The paper focuses on most challenging issues of cardiovascular risk factors (RFs) correction via comprehensive cardiac rehabilitation (CR) programs in patients with CHD and AO. Based on large randomized clinical trials results, intensive behavioral interventions in the form of counselling are beneficial for such patients especially during the long-term support stage. They produce small but important changes in health behaviors (which translate into weight reduction, more healthy nutrition and higher physical activity) and improve selected intermediate clinical endpoints. PMID- 29466183 TI - [Pulmonary arterial hypertension and chronic heart failure as dasatinib cardiotoxicity. A case report]. AB - Modern treatment of patients with oncohematological diseases has allowed to achieve remission or even convalescence in many cases. One of ambitious aims put forward by the hematological society is 100% survival and preservation of quality of life in patients with chronic myeloid leukemia (CML). This hope is related with the emergence of targeted therapy for CML. The second-generation tyrosine kinase inhibitor, dasatinib, which is used for treatment of CML, can occasionally induce severe pulmonary hypertension (PH). We presented here a case report of such cardiotoxicity, which was evident as PH and heart failure in a young female patient with CML treated with dasatinib. Information from published reports about this type of cardiotoxicity is provided. At present time, dasatinib is beginning to be extensively used also in other oncological diseases. For this reason, cardiologists and physicians should be aware of this cardiotoxicity, which can cause heart failure in dasatinib-treated patients.

AB - AIM: To identify factors affecting effective management of patients with myocardial infarction for preventing recurrent coronary events in the outpatient setting. MATERIALS AND METHODS: The study group consisted of patients (n=111) with recurrent myocardial infarction. The control group consisted of patients with primary myocardial infarction (n=89) after percutaneous coronary intervention. Social and demographic, clinical and behavioral factors (weight loss, smoking cessation, adherence to therapy, physical and psychological rehabilitation) were evaluated. RESULTS: Risk factors contributing to the development of repeated MI were as follows: patients' age, concomitant polyvascular and multivessel disease, arterial hypertension, hypercholesterolemia, excess weight and smoking, poor adherence to the recommendations of cardiologists and general physicians. CONCLUSION: The analysis of the effectiveness of the management of patients with myocardial infarction demonstrated the importance of the outpatient rehabilitation in preventing repeated acute coronary events.

AB - AIM: To study indexes of efficacy, safety and compliance for different ASA forms (Aspirin-Cardio, Cardiomagnyl, Thrombo ASS) used in stable IHD. MATERIALS AND METHODS: An open, cross-sectional study compared three groups of patients consisting of 200 patients each who had stable IHD and a high risk of gastrointestinal disorders and who received a long-term antiaggregant monotherapy with one of ASA drugs (group 1, Aspirin Cardio; group 2, Thrombo ASS; group 3, Cardiomagnyl). Efficacy, safety and compliance with the treatment were evaluated using standard tests and analogue scales; dyspepsia symptoms were evaluated using a special, additionally developed questionnaire. RESULTS: The Aspirin-Cardio treatment reduced the mean score of GI symptom severity from the questionnaire (1.4-1.6 times, r=0.001), requirement for proton pump inhibitors (r=0.002) and endoscopy during the ASA treatment the mean score of GI symptom questionnaire >3 predicted non-compliance or insufficient compliance with a diagnostic sensitivity of 58.9 % and specificity of 56.3 % (r=0.002), which makes this value a threshold for considering a modification of the treatment. CONCLUSION: Aspirin-Cardio is characterized by better safety in respect of GI symptoms and better compliance with the treatment during long-term prophylactic therapy. The proposed questionnaire for evaluation of GI symptoms can be used for specifying indications and modifying the treatment tactics.

AB - AIM: To evaluate clinical value copeptin and matrix metalloproteinases in men with acute coronary syndrome (ACS). MATERIALS AND METHODS: The study included 152 men with ACS. After evaluation of the traditional markers of myocardial damage, the patients were divided into 2 groups: the first group included patients with myocardial infarction (MI) - 84 people, the average age was 56.6+/-1.0 years, the second - with unstable angina (UA) - 68 at the age of 61,4+/-1.2 years. All patients at admission and after 6 hours and on day 6 of hospitalization were evaluated for the level of CPK MB, troponin I, copeptin, MMP-1, MMP-2, MMP-7, MMP 9 and TIMP-1. RESULTS: Concentration of copeptin at admission in patients with it is 3.5 times higher than in the group with UA and significantly higher than that of control group. To 6-th day of hospitalization, the concentration of copeptin reduced, but nonetheless remains significantly higher than in the control group (0,9+/-0,1 vs. 0.2+/-0,0, p=0.000) without significant differences with group UA. The level of MMP-1 and MMP-2 in patients with MI and UA at admission higher than in the control group, and in case of MI these levels are significantly higher than in case of UA. CONCLUSION: The obtained data indicates the possibility of using copeptin as a marker of myocardial damage. Additionally, it indicates myocardial damage an increase in the level of MMP-1, MMP-2 and MMP-7. PMID- 29466188 TI - [Incidence of sinus node dysfunction in patients with long-standing, persistent atrial fibrillation who require simultaneous surgical correction of mitral and tricuspid valve defects and the "Maze IIIB" procedure]. AB - BACKGROUND: Atrial fibrillation (AF) is the most common disorder of heart rhythm. A series of "Maze" surgery was developed, among which the "Maze III" modification is presently a gold standard for surgical treatment of AF. AIM: To study the sinoatrial node (SAN) function before and after the "Maze III" surgery. MATERIALS AND METHODS: The study included 100 patients (48 males) with persistent and long standing persistent AF and valve abnormality. Mean age of patients was 59 years and mean AF duration - 4 years. Tachysystolic AF prevailed (62 %); normosystolic AF was observed in 31 % of patients; and bradysystolic - in 7 % of patients. Electric cardioversion was performed for all patients according to the standard method. After successful recovery of the sinus rhythm, the endocardial electrophysiological study (EPS) of the heart was performed. Correction of valve pathology and the "Maze IIIB" surgery were performed on days 1-2 following EPS. The SAN function was evaluated by the time of function recovery (SAN TFR). RESULTS: Using electric cardioversion, the sinus rhythm was restored in all patients. EPS showed abnormal prolongation of the corrected time for the SAN function recovery (CTSANFR) and sinoatrial conduction time (SACT) in 11 % of patients. In 2 % of patients, the abnormal prolongation of SACT was an isolated conduction disorder. In total, 13 % of patients had SAN dysfunction (SAND). These patients received implantable electric cardioverters after a surgical intervention (correction of valve abnormality and "Maze III"). The sinus rhythm recovered immediately after the surgery. On day 7, steady sinus rhythm was observed in 46 % of patients. During the postperfusion period and on the first day postsurgery, 62 % of patients had replacement atrioventricular nodal rhythm. By the time of discharge from the hospital, the nodal rhythm was observed in 25 % of patients. Starting from day 2, the replacement atrial rhythm developed in 13 % of patients, and by the time of discharge from the hospital, 24 % of patients had a stable atrial rhythm. CONCLUSION: Effectiveness of the surgical treatment for persistent and long-standing persistent AF (modified "Maze IIIB" surgery with simultaneous correction of the mitral valve (MV) and the tricuspid valve (TV)) in the early postsurgery period was 95 %. According to data of preoperative endocardial EPS, SAND was observed in 13 % of patients. Following the surgical correction of MV and TV defects and the criomodification of the "Maze IIIB" surgery, signs of SAND requiring implantation of an electric cardioverter were observed in a total of 24 % of patients. PMID- 29466189 TI - [Interventional treatment in patients with myocarditis: Pro and Contra]. AB - AIM: Ventricular tachyarrhythmias (VTs) are often encountered in patients with inflammatory heart diseases. VT can become lifethreatening in patients with myocarditis, and the management may vary in different types of myocarditis. Purpose of the study is to describe VT characteristics in patients with verified myocarditis, and to evaluate the efficacy and safety of VT management, when tailored to the type of myocarditis. MATERIALS AND METHODS: Study population comprised: 56 patients with morphologically verified myocarditis; 18 patients with primary cardiomyopathy (control group). All patients underwent full clinical evaluation, endomyocardial biopsy (including immunohistochemical analysis). Forty (54 %) patients underwent radiofrequency catheter ablation of VT. An implantable cardioverter-defibrillator (ICD) was inserted in 17 patients. RESULTS: There was no statistically significant difference between myocarditis and primary cardiomyopathy groups by demographic and echocardiographic data. In myocarditis group, nonsustained VT and/or frequent premature ventricular beats were seen in 59 % of patients; sustained VT in 12,5 % subjects, 1 patient had a history of ventricular fibrillation. VT ablation was associated with a significant decrease in VT recurrence (p=0,0009) during the follow-up period. Active myocarditis was associated with a higher VT recurrence rate (67 % in active vs. 19 % in borderline myocarditis). Among patients with ICD implantation, only one subject (with active myocarditis at admission) had life-threatening ventricular arrhythmia. CONCLUSION: In this selected group of patients with verified myocarditis and clinically significant VTs, catheter ablation seems at least partly effective. Patients with borderline myocarditis and symptomatic VTs may benefit from ablation. Therefore, morphological diagnostic of myocarditis can be a key point in choice of treatment.

AB - AIM: To study heart structure and function parameters and hepatolienal blood flow in patients with virus-induced cirrhosis (VIC). MATERIALS AND METHODS: 95 patients with VIC (mean age, 38.6; disease duration, 4.5 years) were evaluated. Doppler EchoCG and Doppler ultrasonic examination of hepatolienal vasculature (VIVID E 95 apparatus) were performed. The control group consisted of 19 healthy individuals. Statistical analysis was performed using the Statistica 6.0 software. RESULTS: The study of hepatolienal blood flow showed that the splanchnic artery blood flow velocity was increased by 25%, the hepatic vein blood flow velocity was increased by 13%, and splanchnic arteries and veins were dilated. 24% of VIC patients had moderate pulmonary hypertension associated with a 20% dilatation of inferior vena cava (p=0.007), a 28% increase in hepatic vein blood flow velocity (p=0.0003), and a 13% decrease in portal vein diameter (p=0.001). Four types of left ventricular (LV) geometry were identified: 40% of VIC patients had normal geometry; 17% of patients had concentric hypertrophy; 23% of patients had concentric remodeling; and 19% had eccentric hypertrophy. Features of hepatolienal blood flow were related with the LV geometry type. LV diastolic filling was impaired in 44.3% and RV diastolic filling - in 33% of patients. In patients with VIC, the disturbed diastolic function was associated with 25% reduced hepatic vein blood flow velocity (p=0.05) whereas development of RV diastolic dysfunction was associated with 6% reduced portal vein diameter (p=0.04), 17% dilated portal vein (p=0.006), and 25% decreased portal vein blood flow velocity (p=0.001). Anti-viral therapy resulted in improvement of some hepatolienal blood flow parameters. Parameters of splanchnic circulation were correlated with cardiodynamic parameters with correlation coefficients from 0.51 to 0.95 at p.

AB - AIM: The current study was aimed at assessing the effectiveness and the impact of a long-term education program, in both inpatient and outpatient treatment settings, on adherence to treatment and the quality of life 5 years after heart valve replacement. MATERIALS AND METHODS: All the patients were randomly included into two study groups. The study group patients (n=176) underwent the long-term education program in both inpatient and outpatient treatment settings. The control group (n=108) consisted of patients who underwent only an inpatient education program. Adherence to treatment and the quality of life were assessed before education, at the end of the inpatient and outpatient education and 5 years after heart valve replacement. Patients' treatment adherence was estimated with the Davydov's questionnaire, and the quality of life - with the 36-Item Short Form Health Survey. RESULTS: After the completion of the education program, the integral index reflecting patients' adherence to treatment in the study group remained at the same level, but was 1.4-fold higher compared to the control group in the 5-year follow-up. The long-term education program is associated with improved quality of life, mainly due to emotional well-being. The study reported a correlation between physical functioning and emotional well-being and the integral index reflecting patients' adherence to treatment during the follow-up period. CONCLUSION: The long-term education program in both inpatient and outpatient treatment settings contributed to improved patients' adherence to treatment and the quality of life, mainly due to physical functioning. The inpatient education program was associated with poor patients' adherence to treatment and the quality of life 5 years after heart valve replacement. PMID- 29466192 TI - [Factors associated with levels of interleukins -18, -8, and -6 in hypertensive patients at high and very high cardiovascular risk]. AB - AIM: To identify the most significant factor influencing blood levels of cytokines in patients at high and very high cardiovascular risk. MATERIALS AND METHODS: A patient base from the "Management of chronic patients with multiple diseases" project was analyzed. 523 patients (mean age, 87+/-17.8) were included. Plasma samples were analyzed for concentrations of sodium, creatinine, IL-1, IL 2, IL-4, IL-6, IL-8, IL-10, IL-18, and NT-proBNP. GFR was calculated using the CKD-EPI formula. Time-related CHF progression was assessed in one year; the time related progression was considered an increase in CHF stage. Salt consumption was determined using the Charlton: SaltScreener questionnaire at the baseline visit and at one year. Low-salt diet containing 5 g of salt per day was recommended to all patients; 3.5 g of salt per day was recommended to patients with a documented diagnosis of CHF. Statistical analysis was performed using the Statistica 10.0 software. RESULTS: 52.2 % of included patients consumed 6-10 g of salt per day; 43.4 % of patients consumed 10 g of salt or more per day; and only 4.4 % of patients consumed 5 g of salt or less per day. 21 % of included patients were at high risk of cardiovascular complications whereas for the vast majority of patients (79 %), the risk was stratified as very high. Two clusters of patients were formed based on the grade of hypertension, one-year CHF progression, and plasma levels of IL-6, -8, and -18. The one-year progression of CHF most significantly influenced the levels of IL-18, -8, and -6. The IL-6 level was correlated with the NT-proBNP level; an approximately similar degree of correlation was found for NT-proBNP and BP. CONCLUSION: Therefore, the performed statistical analysis determined correlations between the following factors: IL-6 level, NTproBNP level, and one-year CHF progression.

During a three-month period of recurrent syncope, the patient was managed by the family doctor and at pulmonology and cardiology departments for different diagnoses. Due to an uncertainty in diagnosis, the patient was moved to a hospital where he underwent echocardiographic examination and duplex scanning of right leg veins, which detected a 49.3 mm right leg venous thrombus with a free-floating head in the right common femoral vein. Retrospectively, recurrent pulmonary artery thromboembolism was diagnosed. Thrombectomy and ligation of the right superficial artery were performed; an approximately 17 cm long thrombus was removed; the anticoagulant treatment was administered with a beneficial effect. PMID- 29466194 TI - [The Role of the I/D Polymorphism of the ACE Gene in the Development of Atrial Fibrillation]. AB - OBJECTIVE: To study associations of I / D polymorphism of the ACE gene with risk of atrial fibrillation (AF) with the aim of detecting groups of patients prone to development of this disease. MATERIALS AND METHODS: We examined 90 probands with confirmed diagnosis of AF and 144 their I, II, III degrees relatives. These families constituted a core group of our study. The control group comprised 100 relatively healthy people without history of cardiovascular diseases. Methods used in all patients included clinical examination, electrocardiography, echocardiography, Holter ECG monitoring, veloergometry, transesophageal left atrial pacing, molecular-genetic tests. RESULTS: We found statistically significant predominance of genotype II homozygous carriers among probands with primary AF compared with the control group (30.0+/-7.2 % and 14.0+/-3.5 %, respectively; p=0.028). Homozygous carriers of DD genotype statistically significantly prevailed in the control group compared with group of probands with primary AF (36.0+/-4.8 % and 15.0 %+/-5.6 %; p=0.014). Carriers of homozygous genotype II for common allele statistically significantly prevailed among probands with secondary AF compared with the control group (34.0+/-6.7 % and 14.0+/-3.5 %, respectively; p=0.004). Homozygous carriers of DD genotype for the rare allele statistically significantly prevailed among control subjects compared to probands with secondary AF (36.0+/-4.8 % and 10.0 %+/-4.2 %, respectively; p=0.001). CONCLUSION: Thus, compared with controls statistically significant preponderance of carriers of homozygous genotype II for common allele was found among probands with both primary and secondary AF. At the same time compared with probands there was a statistically significant predominance of homozygous carriers of DD genotype for the rare allele in the control group. Our findings suggest the heterogeneous nature of AF and confirm that DD genotype homozygosity can be protective against the development of AF. PMID- 29466195 TI - [Nerve Growth Factor in Patients With Arterial Hypertension: Neuropsychical, Hemodynamic, Metabolic Relationships]. AB - AIM: To investigate the changes of serum nerve growth factor (NGF) level in patients with arterial hypertension (AH) and obesity in dependence on the degree of psycho-emotional stress and physical activity. MATERIALS AND METHODS: We examined 76 male patients with stage I and II AH with mean age 46.75+/-0.56 years (36 patients with and 40 without obesity). Control group consisted of 26 individuals without AH, obesity, and cardiovascular diseases. All patients underwent ambulatory blood pressure (BP) monitoring. Serum concentrations of NGF beta-subunit and cortisol were determined by enzyme linked immunosorbent assay. For assessment of levels of psycho-emotional stress, reactive and personal anxiety, and physical activity we used Psychological Stress Measure (PSM-25), the Spielberger-Khanin questionnaire, and brief International Physical Activity Questionnaire (IPAQ), respectively. RESULTS: Level of NGF in patients with AH and obesity (0.94+/-0.28 rhog/ml) was higher than in non-obese patients with AH (0.21+/-0.06 rhog/ml; p=0.018) with highest figures in patients with insufficient physical activity and high level of psychoemotional stress. In all groups of patients there was unidirectional reverse correlation between serum NGF and cortisol levels. According to ambulatory BP monitoring, NGF level was inversely proportional to systolic and diastolic BP variability in patients with AH and obesity and in the control group. Reduced serum concentration of NGF was associated with increased levels of reactive and personal anxiety. CONCLUSION: Obtained data suggests that NGF plays an important role in complex multifactorial interactions between neuropsychic, cardiovascular and metabolic processes.

AB - PURPOSE: to determine the role of adipokines and vascular remodeling in formation of osteoporosis in idiopathic pulmonary arterial hypertension (IPAH). MATERIALS AND METHODS: Functional and hemodynamic parameters, bone mineral density (BMD) T score in lumbar spine (LS) and femoral neck (FN), blood serum levels of leptin, adiponectin, visfatin and endothelin-1 were measured in 27 patients with severe IPAH and 30 healthy volunteers. RESULTS: Half of IPAH patients had osteoporosis. Serum levels of leptin, adiponectin, visfatin and endothelin-1 in IPAH group were higher than in healthy volunteers. BMD T-score was directly related to results of 6-minute walk test and inversely related to pulmonary vascular resistance (PVR). Circulating adiponectin and visfatin concentrations correlated with PVR; endothelin-1 concentration was directly related to pulmonary arterial systolic pressure, cardiac index and PVR. Relations between BMD T-score and circulating adiponectin, visfatin, and endothelin-1 were inverse. Positive correlations existed between serum adiponectin, visfatin and endothelin-1 levels. CONCLUSION: Results of our study confirm the important role of adipokine and endotheline dysregulation in development of hemodynamic disorders in severe IPAH and evidence for their possible involvement in formation of osteopenic syndrome.

AB - Use of highly concentrated ethyl esters of polyunsaturated fatty acids after myocardial infarction (MI) and in patients with heart failure was associated with lower mortality. The goal of this analysis was to perform cost-utility analysis of the use of highly concentrated ethyl esters of polyunsaturated fatty acids after MI (with help of a Markov model) and to find whether its use in some group of patients led to decrease in budget costs. As a result, we have shown that use of highly concentrated ethyl esters of polyunsaturated fatty acids after MI leads to increase in quality-adjusted life expectancy on 0.5 QALY, with incremental cost-effectiveness ratio of 105 thousand rubles per QALY, and net monetary benefit of 780.5 thousand rubles. In the patient subpopulation that receives highly concentrated ethyl esters of polyunsaturated fatty acids for arrhythmia prevention after coronary artery bypass the estimated decrease of budget cost varies between 6 and 50% depending on denominator used.

AB - AIM: to study carotid plaques structure in patients with acute coronary syndrome by ultrasound duplex scanning. MATERIALS AND METHODS: We included in this study143 patients with acute coronary syndrome (ACS) aged 32-83 years and 28 patients with documented coronary heart disease (CHD) aged 46-83 years. Duplex scanning of carotid arteries was carried out with Philips iU22 ultrasound system and L9-3 linear array transducer. Atherosclerotic plaques in CCA, CCA bifurcation, and ICA from right and left side were investigated. Off-line analysis of B-mode images and plaque gray scale median (GSM) was performed with computer semiautomated workstation MultiVox. RESULTS: 378 plaques of ACS and 59 plaques of CHD patients were studied. We assessed traditional (heterogenous structure, hypoechogenic component, irregular plaque surface) as well as additional (positive remodeling, "layered" structure of plaque, local calcification) criteria of plaque instability. In ACS compared with CHD group there were more plaques with hypoechogenic component (43.4 and 28.8%, p=0.0459), heterogenous structure (77.8 and 64.4%, p=0.0327), irregular surface including irregularities more than 2.0 mm (22.5 and 6.8%, p=0.0048, respectively). There was significant difference in "layered" structure (55.7 and 35.8%, p=0.0011) and insignificant difference in positive remodeling (16.3 and 7.5%, p=0.06, respectively). There were no differences of GSM value (53.1 and 57.2, p=0.24) and local calcification (23.2 and 24.5%, p=0.23, respectively). CONCLUSION: In our study ultrasound duplex scanning revealed that signs of plaque instability in carotid arteries in patients with ACS were more frequent than in patients with stable CHD. The newly introduced parameter "layered" structure of atherosclerotic plaque was found to be most significant. PMID- 29466207 TI - [Hypertrophic Cardiomyopathy and Ischemic Heart Disease. Variants of Combination Pathology]. AB - The issues of epidemiology and pathophysiology of hypertrophic cardiomyopathy (HCMP), as well as the search for its additional clinical-instrumental and genetic markers, environmental factors capable to influence the formation of its clinical variant and prognosis are subjects of great interest to the modern scientific community. Besides genetic markers of main neurohumoral systems, and morphofunctional parameters of intracardiac hemodynamics clinical course of the disease is influenced by a complex of concomitant pathology including ischemic heart disease (IHD), joining of which is possible in 10% of cases. IHD substantially aggravates course of HCMP and hampers selection of medical therapy. It should be noted that prognosis of primary hypertrophies is affected by episodes of ischemia of complex genesis and addition of IHD significantly increases risk of sudden death in these patients.

AB - OBJECTIVE: to study medical awareness of cardiovascular risk factors (FR) in hospitalized patients of the cardiac and internal medicine units (CU and IMU). MATERIALS AND METHODS: A total of 100 patients from CU (n=50) and IMU (n=50) of a Moscow city hospital were included into the survey. The patients were interviewed during the I-II days of hospital stay. A special questionnaire was developed including socio-demographic and clinical indicators, open questions on the knowledge of traditional cardiovascular RFs and their target values. RESULTS: Patients of both units did not differ in gender and age. The survey revealed an extremely low awareness of major cardiovascular RFs of patients in both units: practically none of them indicated as RFs for cardiovascular disease elevated cholesterol (0 and 2 %, respectively, p>0.05) and blood pressure (0 % and 2 %, respectively, p>0.05). The majority of patients in both units (74 and 68 %, respectively, p>0.05) reported only 1-2 RFs. Patients in both units often believed that stress is the main cardiovascular RF (66 % and 50 %, respectively, p>0.05). CONCLUSION: The survey revealed a low awareness of cardiovascular RFs in different types of medical patients at time of hospital admission.

AB - AIM: to study associations between elevated blood plasma concentration of N terminal pro-brain natriuretic peptide (NT-proBNP), risk factors and cardiovascular diseases (CVD) in samples of adult population of Russian Federation (RF) aged 25-64 years. MATERIALS AND METHODS: We analyzed data of examination of representative samples of population of 5 regions of RF obtained within the framework of the multicenter ESSE-RF study (2012-2013). Number of examined subjects was 8 077 (3 176 men). Methods included use of standard questionnaire, measurements of height, body mass, blood pressure (BP), and plasma NT-proBNP level. The following CVD were included into analysis: arterial hypertension (AH), ischemic heart disease (IHD), atrial fibrillation (AF), and stroke. RESULTS: Women compared to men had higher NT-proBNT concentration was higher in women compared to men, in both genders it rose with age. Overall 17.9 % of examinees had elevated NT-proBNT levels (14.2 and 20.3 % among men and women, respectively). Elevated NTproBNP level was associated in men with age, myocardial infarction, angina pectoris, ischemic ECG changes, left ventricular hypertrophy, AF, bradycardia, smoking, in women with age, IHD, ischemic ECG changes, AF, bradycardia, heart rate >=80 bpm, BP >=160/95 mm Hg. CONCLUSION: In studied RF population elevated NT-proBNP level was significantly associated with gender, age, smoking, and CVD. PMID- 29466212 TI - ? PMID- 29466211 TI - [The Role of Macrophages in Repair of Injured Myocardium and Perspectives of Metabolic Reprogramming of Immune Cells for Myocardial Post-Infarction Recovery]. AB - A new trend in modern experimental cardiology is the development of approaches to correction of reparation after myocardial infarction (MI) with the use of specific effects on immune cells. One of the main targets for such interventions is the process of macrophage's polarization in the infarction zone. Proinflammatory M1-macrophages contribute to hampered myocardial repair, in contrast to M2-macrophages that promote regeneration. Currently, there are two main ways of targeted delivery of agents necessary for macrophage reprogramming - inlipoid and inglycan-encapsulated particles. As modulating agents, small interfering RNA and other genetic constructions are usually used. Both these approaches are currently awaiting their translation into cardiology. The most physiological approach to reprogramming of immune cells may consist in attempts to switch the metabolism of the immune cell from glycolytic to oxidative, which allows macrophages to switch from M1 to M2 phenotype. Among possible targets for macrophage reprogramming, it is worthwhile to isolate the protein complex mTORC1, the blocking of which promotes oxidative metabolism, and the transcription factor HIF-1alpha, the blocking of which also facilitates the switching of the metabolism from glycolytic to oxidative one.

AB - Ischemic heart disease (IHD) and acute coronary syndrome are the main cause of sudden cardiac death (SCD). Incidence of SCD in patients after myocardial infarction (MI) is 4-6-fold higher than in general population. The review focuses on electrophysiological changes during acute myocardial ischemia and mechanisms of myocardial electromechanical remodeling in remote period after MI. Current data on arrhythmia substrates and triggers are presented. Nowadays, the main guide for implantable cardioverter-defibrillator (ICD) use for primary prevention of SCD is reduced left ventricular ejection fraction. The significance of this parameter has been repeatedly demonstrated in large randomized studies. However, the use of a single indicator cannot solve the problem. In this review we present analysis of modern additional predictors of fatal arrhythmias which are available in clinical practice, as well as the perspective for further research of this highly important scientific, clinical, and social problem.

Abnormal catecholamine release has been hypothesized to be the main cause of TCM. Myocardial infarction (MI) is associated with release of large amounts of catecholamines. We present here two cases in which patients simultaneously suffered from acute MI and TCM. In these elderly women without prior history of severe somatic diseases we have not revealed any external stressing factor responsible for the initiation of the disease. Therefore, we have considered primary coronary event (acute MI) to be a triggering factor of TCM manifestation. PMID- 29466218 TI - [Structural and Functional Properties of the Left Atrium in Healthy Volunteers and Patients With Atrial Fibrillation: Data of Magnetic Resonance Imaging]. AB - BACKGROUND: in the recent years, there has been an increasing number of publications postulating that data on left atrial (LA) structure obtained by late gadolinium enhancement magnetic resonance imaging (LGE MRI) can improve the management of patients with atrial fibrillation (AF). At the same time, similar data regarding healthy LA myocardium is limited. AIM: to assess structural and functional properties of LA in healthy volunteers (HV) using cardiac magnetic resonance (CMR) (including LGE MRI); to compare these properties in patients with AF and HV. MATERIALS AND METHODS: We included in this study 53 patients with AF (28 without signs of cardiovascular disease, 28 with hypertension) and 23 HV of similar age. All enrolled persons underwent MRI. Cine-MRI was used to assess end diastolic volume of LA (LA EDV), LA ejection fraction (LA EF), left ventricular diastolic index (LV DI). High resolution LGE MRI was performed 15-20 min after gadoversetamide injection using IR 3D gradient echo pulse sequence with fat saturation (TI 290-340 ms, TE 2.44 ms, TR 610-1100ms). On obtained images LA was segmented semiautomatically. LA fibrosis quantification was performed using developed software LGE Heart Analyzer. The extent of fibrosis was represented as percent of LA myocardium volume. Fibrosis location was determined on reconstructed rotating 3D LA model. RESULTS: Compared with patients HV had lower LA EDV (59 [54; 78] ml and 79 [65.5; 86.6] ml, r=0.043, respectively), higher LA EF (56.1 [49; 63.2] % and 44.5 [34.5, 54.5] %, r=0.03, respectively), and lower extent of LA fibrosis (0.7 [0.05; 3.5] % and 9.1 [1.7; 18] %, r.

AB - OBJECTIVE: To assess the impact of type 2 diabetes mellitus (T2DM) on prognosis of patients hospitalized because of acute decompensated heart failure (ADHF). MATERIALS AND METHODS: We analyzed data of the hospital register of ADHF which comprised information on 735 patients (254 [35%] with T2DM) consecutively admitted in 2010-2011. Median follow-up was 1790 days. RESULTS: The presence of T2DM was associated with increased risk of death: during the index hospitalization due to ADHF (hazard ratio [HR] 1.7, 95% confidence interval [CI] 1.0-2.8), within 18 months (HR 1.4, 95% CI 1.0-1.8), and within 5 years (HR 1.3, 95% CI 1.0-1.5). CONCLUSIONS: T2DM is common among acute decompensated heart failure patients (up to 35% of cases). T2DM is an independent risk factor of death during the index hospitalization and over the next 18 months and 5 years.

AB - PURPOSE: To assess the suppression of tumorogenicity 2 (ST2) and copeptin significance for risk stratification of patient (pts) with acute decompensated heart failure (ADHF) during long-term follow-up compared with traditional risk factors. METHODS: We included in a prospective study 159 pts with ADHF. Blood samples to determine copeptin, sST2, NT-proBNP and hsTnT concentration were collected at admission and at discharge from the hospital. Serial determination of biomarker concentration was performed at 3, 6 and 12 months of follow-up. The combined primary end point of the trial included cardiovascular (CV) death, hospitalization due to HF, episodes of HF deterioration requiring additional intravenous diuretics and CV death with successful resuscitation. RESULTS: During 1-year follow-up (295.3+/-113.2 days) 56 pts (35.2%) had 78 (49.1%) cardiovascular events. Biomarker concentrations in low risk pts (without CV events) were significantly lower compared with high risk pts (with CV events). Discharge copeptin and NT-proBNP values were comparable for pts risk stratification: AUC=0.727 (95% CI 0.637-0.816), r.

AB - AIM: To perform a randomized, open-label comparison of average time in therapeutic range (TTR) of international normalized ratio (INR) using two approaches to initial warfarin dosing during hospitalization: the standard method and the one using individual patient characteristics (clinical algorithm - the studied approach). MATERIALS AND METHODS: We randomly assigned 60 patients with different indications for vitamin K antagonist therapy to the studied approach (n=31, intervention group) or to the standard method (n=29, control group). A target INR range for all patients was 2.0 to 3.0. RESULTS: The average TTR and portions of INR values within target range during the whole time of drug dosing turned out to be small. TTR was 22.4% with standard method and 21.4% with clinical algorithm, which was well below desired 60%. CONCLUSION: The opportunities for achieving target INR in inpatient settings, regardless of warfarin dosing regimen, are limited. PMID- 29466224 TI - ?

Subclinical changes in RV function are of great importance for the diagnosis and assessment of prognosis of multiple cardiovascular as well as non-cardiac pathologies. Two-dimensional speckle tracking allows to assess longitudinal strain of the RV myocardium and to detect pathological changes before their clinical manifestations. Three dimensional echocardiography enables calculation of the RV ejection fraction, what was not possible before with the use of ultrasound. Currently, both methods are promising for a comprehensive assessment of RV function. PMID- 29466226 TI - [The Role of MicroRNA in Atherogenesis].

PMID- 29466231 TI - Transcytosis of payloads that are non-covalently complexed to bispecific antibodies across the hCMEC/D3 blood-brain barrier model. AB - A transcellular shuttle system was generated for the delivery of non-covalently linked payloads across blood-brain barrier (BBB) endothelial cells. Transcytosis enabling shuttles are composed of bispecific antibodies (bsAbs) that simultaneously bind transferrin receptor (TfR) and haptens such as digoxigenin or biocytinamide. Haptenylated payloads are attached to these vehicles via non covalent hapten-antibody complexation. This enables targeting to and internalization into human BBB-derived microvascular endothelial hCMEC/D3 cells. In contrast to other shuttles, this system does not require special affinities or formats of their TfR-binding moieties for transcytosis and subsequent release. Non-covalent payload complexation to bsAb is flexible and robust, works for a multitude of payloads and enables separation of payloads from shuttles during transcytosis. Released payloads can enter the brain without connected bsAb entities, minimizing potential interference with distribution or functionality. Intracellular separation of shuttle and payload and recycling to cell surfaces may also enable recharging of the cell-bound BBB shuttle with payload for subsequent (merry-go-round) transport cycles. PMID- 29466232 TI - Analytical performance of an automated volumetric flow cytometer for quantitation of T, B and natural killer lymphocytes. AB - BACKGROUND: Quantitation of lymphocyte subsets (B cells, T cells, CD4 and CD8 T cells and NK cells) classically relies on quantitation of lymphocytes and immunophenotyping by flow cytometry. AQUIOS CL (Beckman Coulter) is a fully automated system that performs an onboard volumetric cell count, automatically processes the sample (staining, lysing and fixation) and analyzes the results. We compared AQUIOS CL to a dual-platform analysis and evaluated analytical performance. METHODS: We evaluated precision, sample stability, inter-sample carryover, linearity and interpanel consistency. AQUIOS CL was compared to a dual platform method (Sysmex XE-5000 and BD FACSCanto-II). A total of 113 patient samples were included: 45 from posttransplant patients, 44 from children and 24 random routine samples. The degree of automation was scored through the need of manual revisions triggered by AQUIOS CL run notifications and run flags. RESULTS: Intrarun and interrun variability was <9.1% with dedicated control material and <32.1% with patient samples. Relative values of lymphocyte subsets could be determined up to 48 h after venipuncture when the sample was kept at room temperature. There was no carryover and good linearity. Interpanel consistency was 3.3% for relative values and 9.4% for absolute values. Method comparison showed good analytical correlation between AQUIOS CL and a dual-platform method. Thirty-five percent of the samples triggered a run notification. In 74% of these samples, the results could be accepted without intervention, so in 26% of all samples, an unnecessary notification was generated. CONCLUSIONS: AQUIOS CL allows for reliable fully automated immunophenotyping of lymphocyte subset quantitation. Gating algorithms could be further improved. PMID- 29466233 TI - Anti-streptavidin IgG antibody interference in anti-cyclic citrullinated peptide (CCP) IgG antibody assays is a rare but important cause of false-positive anti CCP results. AB - BACKGROUND: The detection of anti-cyclic citrullinated peptide (anti-CCP) IgG antibodies in blood is mainly used for the diagnosis of rheumatoid arthritis. Falsely elevated anti-CCP IgG antibodies due to anti-streptavidin IgG antibodies were suspected in our laboratory. METHODS: In this study, we evaluated, in a standardized approach, the prevalence of anti-streptavidin IgG antibodies in a primary care setting and the effect of anti-streptavidin IgG antibodies on anti CCP IgG assays from three different important commercial manufacturers (Abbott, Roche Diagnostics, Thermo Fisher Scientific). Three different populations were consecutively and prospectively studied: serum samples from 1000 ambulatory patients, 286 serum samples from patients for which anti-CCP was requested and 89 serum samples from patients which had previously given a positive anti-CCP result on Architect(r) i2000. RESULTS: The frequency of confirmed anti-streptavidin IgG positive samples detected in this study was 0.6% (8/1375). Anti-CCP IgG was determined on the eight samples with confirmed anti-streptavidin IgG antibodies: with the Cobas(r) method, seven positive anti-CCP results were observed and five positive anti-CCP results with the Architect(r) method. No positive anti-CCP IgG results were obtained with the EliATM method. Rheumatoid factor was negative in these eight samples. CONCLUSIONS: Anti-streptavidin IgG antibodies rarely cause false-positive results in some anti-CCP assays. However, despite being an infrequent assay problem, it could possibly lead to diagnostic confusion or even an incorrect diagnosis of rheumatoid arthritis.

AB - The white adipose tissue (WAT) exhibits great plasticity and can undergo "browning" and acquire features of the brown adipose tissue (BAT), which takes place following cold exposure, chronic endurance exercise or beta3-adrenergic stimulation. WAT that underwent browning is characterized by the presence of "beige" adipocytes, which are morphologically similar to brown adipocytes, express uncoupling protein 1 (UCP1) and are considered thermogenically competent. Thus, inducing a BAT-like phenotype in the WAT could promote energy dissipation within this depot, reducing the availability of substrate that would otherwise be stored in the WAT. Importantly, BAT in humans only represents a small proportion of total body mass, which limits the thermogenic capacity of this tissue. Therefore, browning of the WAT could significantly expand the energy-dissipating capacity of the organism and be of therapeutic value in the treatment of metabolic diseases. However, the question remains as to whether WAT indeed changes its metabolic profile from an essentially fat storage/release compartment to an energy dissipating compartment that functions much like BAT. Here, we discuss the differences with respect to thermogenic capacity and metabolic characteristics between white and beige adipocytes to determine whether the latter cells indeed significantly enhance their capacity to dissipate energy through UCP1-mediated mitochondrial uncoupling or by the activation of alternative UCP1-independent futile cycles.

AB - An interpretive descriptive qualitative study was conducted to explore the characteristics and outcomes of mentoring used for implementing nursing practice guidelines. We interviewed six mentees, eight mentors, and four program leaders who were involved in the Registered Nurses' Association of Ontario fellowship program in Ontario, Canada. Inductive content analysis was used and study rigor was verified using triangulation of findings and member checking. Mentors were described as accessible, dedicated, and having expertise; mentees were described as enthusiastic, self-directed, and having mixed levels of expertise. The mentoring process included building relationships, developing learning plans, and using teaching and learning activities guided by learning plans to support development of mentees. Mentoring was described as positively impacting mentoring relationships, mentees, mentors, and organizations. A central feature of this fellowship program was the learning plan used to identify mentees' needs, guide mentoring activities, and monitor measureable outcomes.

AB - This project is a mixed-methods systematic review on the use of simulation in pre licensure nursing. This research question guided this review: What is the best evidence available upon which to base decisions regarding the use of simulation experiences with pre-licensure nursing students? Searches of CINAHL Plus with Full Text, MEDLINE, and ERIC were performed to identify relevant literature. These searches yielded 1220 articles. After duplicates were removed and titles and abstracts were reviewed for relevance to the inclusion criteria, the remaining 852 articles were independently assessed for quality by pairs of researchers. Forty-seven articles were retained. Findings were grouped into research using high-, medium-, and low-fidelity simulations and a group where researchers included several or all types of simulation. The conclusion is that insufficient quality research exists to guide educators in making evidence-based decisions regarding simulation. More rigorous and multi-site research is needed. PMID- 29466238 TI - Role of reactive oxygen species-total antioxidant capacity status in Telfairia occidentalis leaves-associated spermatoprotective effect: a pointer to fatty acids benefit. AB - Background The present study used reactive oxygen species (ROS)-total antioxidant capacity (TAC) score to understand the role of redox status on the effect of Telfairia occidentalis (TO) on testicular parameters. The fatty acids (FAs) components of methanol extract of TO (METO) and its fractions were also identified with gas chromatography-mass spectrometry. Methods A total of 66 male Wistar rats were randomly divided in a blinded fashion into six oral treatment groups as follows: group I (control, n=6) received 10% ethanol (vehicle for TO administration). Groups II to VI (n=12 rats each) were subdivided into two treatment subgroups (n=6 each) that received 200 mg/kg and 600 mg/kg of METO and its chloroform, petroleum ether, acetone, and ethanol fractions, respectively. All treatments lasted for 30 days. Results The major FAs detected in TO were myristic, palmitic, oleic, linoleic, linolenic, and stearic acids including their esters. Both doses of METO and its fractions increased the semen parameters, TAC and ROS-TAC scores but decreased the ROS when compared with control. Conclusions Using the ROS-TAC score, this study suggests that TO-associated improvement in semen parameters might be partly mediated by a reduction in free radical generation, and that the FAs present in TO might be involved in its spermatoprotective effect.

AB - BACKGROUND: This study aimed to identify the predictive value of basal sex hormone levels for activation of the hypothalamic-pituitary-gonadal (HPG) axis in girls. METHODS: Gonadotropin-releasing hormone (GnRH) stimulation tests were performed and evaluated in a total of 1750 girls with development of secondary sex characteristics. Correlation analyses were conducted between basal sex hormones and peak luteinizing hormone (LH) levels >=5 IU/L during the GnRH stimulation test. Receiver operating characteristic (ROC) curves for basal levels of LH, follicle-stimulating hormone (FSH), LH/FSH, and estradiol (E2) before the GnRH stimulation test were plotted. The area under the curve (AUC) and 95% confidence intervals (CIs) were measured for each curve. RESULTS: The maximum AUC value was observed for basal LH levels (0.77, 95% CI: 0.74-0.79), followed by basal FSH levels (0.73, 95% CI: 0.70-0.75), the basal LH/FSH ratio (0.68, 95% CI: 0.65-0.71), and basal E2 levels (0.61, 95% CI: 0.59-0.64). The appropriate cutoff value of basal LH levels associated with a positive response of the GnRH stimulation test was 0.35 IU/L, with a sensitivity of 63.96% and specificity of 76.3% from the ROC curves when Youden's index showed the maximum value. When 100% of patients had peak LH levels >=5 IU/L, basal LH values were >2.72 IU/L, but the specificity was only 5.45%. CONCLUSIONS: Increased basal LH levels are a significant predictor of a positive response during the GnRH stimulation test for assessing activation of the HPG axis in most girls with early pubertal signs.

Cross-sectional design studies of height show that, during childhood, height standard deviation scores (SDS) declines steadily and reaches a mean adult height at -6.42 and -6.72 SDS. However, there is a lack of knowledge about longitudinal growth and biological variables during puberty for children with achondroplasia. Here we report the growth velocity and biological parameters during puberty in children with achondroplasia. METHODS: The study was an observational, cohort study. A total of 23 patients, 15 girls and eight boys with achondroplasia, who reached adult size were included. Growth data was collected from mid-childhood until final height by the same trained observer. Individual growth curves were estimated by fitting the Preece-Baines model 1 (PB1) to each individual's height for age data. Pubertal development was scored on Tanner scale on each visit. RESULTS: In boys with achondroplasia the mean adult height was 129.18 cm. Age and velocity at peak velocity in puberty were 13.89 years and 4.86 cm/year, respectively. The adolescent gain was 20.40 cm. Mean age at genital development 2 and 5 were 12.16 (0.60) and 14.97 (0.88), respectively. In girls the mean adult height was 118.67 cm. Age and velocity at peak velocity in puberty were 11.45 years and 4.40 cm/year, respectively. The adolescent gain was 19.35 cm. Mean age at breast 2 and 4 were 10.20 (1.24) and 12.49 (1.07), respectively. CONCLUSIONS: Children with achondroplasia experienced an adolescent growth spurt, which was similar in shape and half the magnitude of the non-achondroplasia population. PMID- 29466241 TI - In iodine-induced thyrotoxicosis, steroid therapy today could keep the surgical knife at bay. AB - BACKGROUND: Amiodarone-induced thyrotoxicosis (AIT) type 2, characterized as a destructive thyroiditis, is well described in the medical literature; however, iodine-induced thyrotoxicosis (IIT) is not, though the latter has similar features and can be managed similarly. CASE PRESENTATION: We present a 17-year old female who presented with a history of an intermittent goiter with thyroid function tests (TFTs): thyroid-stimulating hormone (TSH)<0.015 (0.4-4 MUU/mL), free thyroxine (T4)>=6 (0.7-2.1 ng/dL) and total triiodothyronine (T3) 651 (50 200 mg/dL). Thyroid antibodies were all negative. Despite methimazole therapy for 6 weeks, hyperthyroidism proved refractory to medical management. 123I scan uptake was suppressed. With hyperthyroidism being recalcitrant to therapy, a nutritional history revealed consumption of an iodine supplement containing at least 7 times the recommended daily allowance (RDA) for 5 years, contributing to the Jod-Basedow phenomenon. Urinary spot and 24-hour urinary iodine were both elevated. Though a surgical consult was obtained, surgery was cancelled once TFTs improved and then normalized with steroid therapy. The TFTs and urinary iodine levels remained normal post steroid therapy. CONCLUSIONS: We suggest that in addition to the need for a thorough nutritional history, a trial of corticosteroids should be utilized in the management of IIT which can present with findings similar to AIT type 2 which is recalcitrant to thionamide therapy. If successful, corticosteroids may delay or prevent surgical management thus avoiding possible complications with the latter approach. PMID- 29466242 TI - Mindfulness and meditation: treating cognitive impairment and reducing stress in dementia. AB - This study investigates the relationship between mindfulness, meditation, cognition and stress in people with Alzheimer's disease (AD), dementia, mild cognitive impairment and subjective cognitive decline. Accordingly, we explore how the use of meditation as a behavioural intervention can reduce stress and enhance cognition, which in turn ameliorates some dementia symptoms. A narrative review of the literature was conducted with any studies using meditation as an intervention for dementia or dementia-related memory conditions meeting inclusion criteria. Studies where moving meditation was the main intervention were excluded due to the possible confounding of exercise. Ten papers were identified and reviewed. There was a broad use of measures across all studies, with cognitive assessment, quality of life and perceived stress being the most common. Three studies used functional magnetic resonance imaging to measure functional changes to brain regions during meditation. The interventions fell into the following three categories: mindfulness, most commonly mindfulness-based stress reduction (six studies); Kirtan Kriya meditation (three studies); and mindfulness-based Alzheimer's stimulation (one study). Three of these studies were randomised controlled trials. All studies reported significant findings or trends towards significance in a broad range of measures, including a reduction of cognitive decline, reduction in perceived stress, increase in quality of life, as well as increases in functional connectivity, percent volume brain change and cerebral blood flow in areas of the cortex. Limitations and directions for future studies on meditation-based treatment for AD and stress management are suggested. PMID- 29466243 TI - G protein-coupled receptor-receptor interactions give integrative dynamics to intercellular communication. AB - The proposal of receptor-receptor interactions (RRIs) in the early 1980s broadened the view on the role of G protein-coupled receptors (GPCR) in the dynamics of the intercellular communication. RRIs, indeed, allow GPCR to operate not only as monomers but also as receptor complexes, in which the integration of the incoming signals depends on the number, spatial arrangement, and order of activation of the protomers forming the complex. The main biochemical mechanisms controlling the functional interplay of GPCR in the receptor complexes are direct allosteric interactions between protomer domains. The formation of these macromolecular assemblies has several physiologic implications in terms of the modulation of the signaling pathways and interaction with other membrane proteins. It also impacts on the emerging field of connectomics, as it contributes to set and tune the synaptic strength. Furthermore, recent evidence suggests that the transfer of GPCR and GPCR complexes between cells via the exosome pathway could enable the target cells to recognize/decode transmitters and/or modulators for which they did not express the pertinent receptors. Thus, this process may also open the possibility of a new type of redeployment of neural circuits. The fundamental aspects of GPCR complex formation and function are the focus of the present review article. PMID- 29466244 TI - Biomarkers for detection, prognosis and therapeutic assessment of neurological disorders. AB - Neurological disorders have aroused a significant concern among the health scientists globally, as diseases such as Parkinson's, Alzheimer's and dementia lead to disability and people have to live with them throughout the life. Recent evidence suggests that a number of environmental chemicals such as pesticides (paraquat) and metals (lead and aluminum) are also the cause of these diseases and other neurological disorders. Biomarkers can help in detecting the disorder at the preclinical stage, progression of the disease and key metabolomic alterations permitting identification of potential targets for intervention. A number of biomarkers have been proposed for some neurological disorders based on laboratory and clinical studies. In silico approaches have also been used by some investigators. Yet the ideal biomarker, which can help in early detection and follow-up on treatment and identifying the susceptible populations, is not available. An attempt has therefore been made to review the recent advancements of in silico approaches for discovery of biomarkers and their validation. In silico techniques implemented with multi-omics approaches have potential to provide a fast and accurate approach to identify novel biomarkers. PMID- 29466245 TI - Effect of the Arctic terrestrial plant Ranunculus hyperboreus on LPS-induced inflammatory response via MAPK pathways. AB - The Arctic flora hosts a limited number of species due to its extreme environmental conditions which also yield novel and unique secondary metabolites from withstanding plants. Considering a lack of research on bioactivity potential of Arctic flora, Ranunculus hyperboreus, an Arctic plant, was studied for its anti-inflammatory potential as a part of ongoing research on discovering novel natural bioactive products. Solvent-based fractions (H2O, n-BuOH, 85% aq. MeOH, n hexane) from R. hyperboreus extract were observed to decrease the elevated nitrate amount during the inflammatory response of lipopolysaccharide-induced mouse macrophage RAW264.7 cells. To some extent, treatment with fractions was able to regulate the expression and protein levels of inflammation-related enzymes, iNOS and COX-2, and pro-inflammatory cytokines, TNF-alpha, IL-1beta, and IL-6. The most active fractions, H2O and 85% aq. MeOH, were suggested to exert their effect through suppressed activation of MAPK pathways, especially JNK. Based on the studies of same species, phenolic glycosides were suggested to be the main active ingredients. To our knowledge, this is the first report of any bioactivity of R. hyperboreus which could be a valuable source of natural bioactive agents against inflammation. PMID- 29466246 TI - Modified aging of elite athletes revealed by analysis of epigenetic age markers. AB - Recent progress in epigenomics has led to the development of prediction systems that enable accurate age estimation from DNA methylation data. Our objective was to track responses to intense physical exercise of individual age-correlated DNA methylation markers and to infer their potential impact on the aging processes. The study showed accelerated DNA hypermethylation for two CpG sites in TRIM59 and KLF14. Both markers predicted the investigated elite athletes to be several years older than controls and this effect was more substantial in subjects involved in power sports. Accordingly, the complete 5-CpG model revealed age acceleration of elite athletes (P=1.503x10-7) and the result was more significant amongst power athletes (P=1.051x10-9). The modified methylation of TRIM59 and KLF14 in top athletes may be accounted for by the biological roles played by these genes. Their known anti-tumour and anti-inflammatory activities suggests that intense physical training has a complex influence on aging and potentially launches signalling networks that contribute to the observed lower risk of elite athletes to develop cardiovascular disease and cancer. PMID- 29466247 TI - Ultraviolet A irradiation induces senescence in human dermal fibroblasts by down regulating DNMT1 via ZEB1. AB - In this study, we report the role of DNA methyltransferase 1 (DNMT1) in ultraviolet A (UVA)-induced senescence in human dermal fibroblasts (HDFs). We show that DNMT1 expression was significantly reduced during UVA-induced senescence, and this senescence could be alleviated or aggravated by the up- or down-regulation of DNMT1, respectively. Expression of the transcription factor zinc finger E-box binding homeobox 1(ZEB1) also decreased after UVA irradiation, following a UVA-induced increase of intracellular reactive oxygen species (ROS). We show that ZEB1 binds to the DMNT1 promoter and regulates its transcription, which, in turn, affects cellular senescence. These changes in DMNT1 and ZEB1 expression following UVA exposure were confirmed in matched skin specimens that had or had not been sun-exposed. On analyzing the promoter methylation of 24 senescence associated genes in these matched skin specimens, we discovered that p53 promoter methylation was significantly reduced in sun-exposed skin. In vitro experiments confirmed that UVA irradiation reduced p53 promoter methylation, and DNMT1 up-regulation could reverse this effect. Collectively, down-regulation of ZEB1 caused by UVA induced ROS could transcriptionally inhibit DNMT1, leading to low methylation level of senescence related proteins p53 and increase its expression, eventually result in cellar senescence. PMID- 29466248 TI - Four common polymorphisms of BRIP1 (rs2048718, rs4988344, rs4986764, and rs6504074) and cancer risk: evidence from 13,716 cancer patients and 15,590 cancer-free controls. AB - Previous studies have showed the associations between various BRCA1-interacting protein 1 (BRIP1) polymorphisms and cancer risk. But, these results were inconsistent. This meta-analysis based on 18 studies involving 13,716 cancer patients and 15,590 cancer-free controls is aimed at to evaluate the relationship between the four common SNPs of BRIP1 (rs2048718, rs4988344, rs4986764, and rs6504074) and cancer risk. The results showed a decreased risk of rs2048718 or rs4986764 for cervical cancer rather than breast cancer in the overall population (P < 0.05). However, rs6504074 was associated with gynecologic cancer risk among overall population (P < 0.05). Further stratification analyses by ethnicity indicated that all 4 polymorphisms (rs2048718, rs4988344, rs4986764, and rs6504074) were strongly related to cancer susceptibility in Chinese people (P < 0.05). This meta-analysis showed that rs6504074 may play a decreased risk of gynecologic cancer in the overall population. Rs4988344, rs4986764, and rs6504074 were significantly related to decreasing cancer risk in Chinese population. PMID- 29466249 TI - Exploiting mitochondrial targeting signal(s), TPP and bis-TPP, for eradicating cancer stem cells (CSCs). AB - Tri-phenyl-phosphonium (TPP) is a non-toxic chemical moiety that functionally behaves as a mitochondrial targeting signal (MTS) in living cells. Here, we explored the hypothesis that TPP-related compounds could be utilized to inhibit mitochondria in cancer stem cells (CSCs). We randomly selected 9 TPP-related compounds for screening, using an ATP depletion assay. Based on this approach, five compounds were identified as "positive hits"; two had no detectable effect on ATP production. Remarkably, this represents a >50% hit rate. We validated that the five positive hit compounds all inhibited oxygen consumption rates (OCR), using the Seahorse XFe96 metabolic flux analyzer. Interestingly, these TPP related compounds were non-toxic and had little or no effect on ATP production in normal human fibroblasts, but selectively targeted adherent "bulk" cancer cells. Finally, these positive hit compounds also inhibited the propagation of CSCs in suspension, as measured functionally using the 3D mammosphere assay. Therefore, these TPP-related compounds successfully inhibited anchorage-independent growth, which is normally associated with a metastatic phenotype. Interestingly, the most effective molecule that we identified contained two TPP moieties (i.e., bis-TPP). More specifically, 2-butene-1,4-bis-TPP potently and selectively inhibited CSC propagation, with an IC-50 < 500 nM. Thus, we conclude that the use of bis-TPP, a "dimeric" mitochondrial targeting signal, may be a promising new approach for the chemical eradication of CSCs. Future studies on the efficacy of 2-butene-1,4-bis TPP and its derivatives are warranted. In summary, we show that TPP-related compounds provide a novel chemical strategy for effectively killing both i) "bulk" cancer cells and ii) CSCs, while specifically minimizing or avoiding off target side-effects in normal cells. These results provide the necessary evidence that "normal" mitochondria and "malignant" mitochondria are truly biochemically distinct, removing a significant barrier to therapeutically targeting cancer metabolism. PMID- 29466250 TI - Evaluation of 209At as a theranostic isotope for 209At-radiopharmaceutical development using high-energy SPECT. AB - The development of alpha-emitting radiopharmaceuticals using 211At requires quantitative determination of the time-dependent nature of the 211At biodistribution. However, imaging-based methods for acquiring this information with 211At have not found wide-spread use because of its low abundance of decay emissions suitable for external detection. In this publication we demonstrate the theranostic abilities of the 211At/209At isotope pair and present the first-ever 209At SPECT images. The VECTor microSPECT/PET/CT scanner was used to image 209At with a collimator suitable for the 511 keV annihilation photons of PET isotopes. Data from distinct photopeaks of the 209At energy spectrum (195 keV (22.6%), 239 keV (12.4 %), 545 keV (91.0 %), a combined 782/790 keV peak (147 %), and 209Po x rays (139.0 %)) were independently evaluated for use in image reconstructions using Monte Carlo (GATE) simulations and phantom studies. 209At-imaging in vivo was demonstrated in a healthy mouse injected with 10 MBq of free [209At]astatide. Image-based measurements of 209At uptake in organs of interest-acquired in 5 min intervals-were compared to ex vivo gamma counter measurements of the same organs. Simulated and measured data indicated that-due to the large amount of scatter from high energy (>750 keV) gammas-reconstructed images using the x-ray peak outperformed those obtained from other peaks in terms of image uniformity and spatial resolution, determined to be <0.85 mm. 209At imaging using the x-ray peak revealed a biodistribution that matched the known distribution of free astatide, and in vivo image-based measurements of 209At uptake in organs of interest matched ex vivo measurements within 10%. We have acquired the first 209At SPECT images and demonstrated the ability of quantitative SPECT imaging with 209At to accurately determine astatine biodistributions with high spatial and temporal resolution. PMID- 29466251 TI - Kinematics and dynamics of the auto-rotation of a model winged seed. AB - Numerical simulations of the auto-rotation of a model winged seed are presented. The calculations are performed by solving simultaneously the Navier-Stokes equations for the flow surrounding the seed and the rigid-body equations for the motion of the seed. The Reynolds number based on the descent speed and a characteristic chord length is varied in the range 80-240. Within this range, the seed attains an asymptotic state with finite amplitude auto-rotation, while for smaller values of the Reynolds number no auto-rotation is observed. The motion of the seed is characterized by the coning and pitch angles, the angular velocity and the horizontal translation of the seed. The values obtained for these quantities are qualitatively similar to those reported in the literature in experiments with real winged seeds. When increasing the Reynolds number, the seed tends to rotate at higher speeds, with less inclination with respect to the horizontal plane, and with a larger translation velocity. With respect to the aerodynamic forces, it is observed that, with increasing Reynolds number, the horizontal components decrease in magnitude while the vertical component increases. The force distribution along the wing span is characterized using both global and local characteristic speeds and chord lengths for the non dimensionalisation of the force coefficients. It is found that the vertical component does not depend on the Reynolds number when using local scaling, while the chordwise component of the force does. PMID- 29466252 TI - INTRAVITREAL INJECTION OF PROPRANOLOL FOR THE TREATMENT OF RETINAL CAPILLARY HEMANGIOMA IN A CASE OF VON HIPPEL-LINDAU. AB - PURPOSE: The purpose of this study was to evaluate the safety and efficacy of intravitreal propranolol for the management of retinal capillary hemangioma in a patient with Von Hippel-Lindau. METHODS: Two intravitreal injections of 50 MUg/0.05 mL propranolol were administered 6 weeks apart in the left eye of a 26 year-old patient with bilateral multiple retinal capillary hemangiomas. Safety and response to therapy were evaluated using electroretinogram, fluorescein angiography, and measurement of visual acuity. Laser photocoagulation was performed in the right eye. RESULTS: One month after the second intravitreal injection of propranolol, fluorescein leakage decreased from the tumors located on the optic nerve head and in the inferonasal retinal periphery. Reduction of the retinal capillary hemangioma vascularity and enhancement of its fibrosis associated with the attenuation of the feeder vessel were also observed. Ophthalmic examination showed no adverse effect except for a mild transient vitreous haziness after each injection. Electroretinogram performed 4 weeks after the first injection revealed no retinal toxicity. CONCLUSION: Intravitreal propranolol showed a therapeutic effect on retinal capillary hemangioma with no short-term adverse effects except a mild transient inflammatory response in a patient with Von Hippel-Lindau. PMID- 29466253 TI - An Outpatient, Dose-Intense, Intravenous Cisplatin and Oral Etoposide Regimen for the Treatment of Advanced, Platinum-Resistant Ovarian Cancer. AB - OBJECTIVES: Advanced-stage, platinum-resistant, ovarian cancer can be treated with dose-intense chemotherapy; one such regimen includes intravenous cisplatin and oral etoposide. To minimize the toxicity associated with weekly cisplatin, pretreatment and posttreatment hydration is required, often necessitating inpatient, overnight admission. We report a shorter, within-day regimen for delivering weekly cisplatin. METHODS: This was a retrospective study to assess the use of standard (inpatient; treatment time of 12 hours) versus modified (outpatient; treatment time of 4 hours) regimens. The primary outcome included all-grade and grade 3/4 adverse events. Secondary outcomes included clinical benefit response and, median progression-free survival and overall survival. RESULTS: Between January 2012 and December 2014, 66 women with metastatic ovarian cancer received dose-intense weekly cisplatin and oral etoposide (n = 45 standard, n = 21 modified). The commonest all-grade adverse events were anemia (96% vs 90%, standard and modified, respectively), fatigue (73% vs 67%), neutropenia (71% vs 76%), hypocalcemia (51% vs 43%), and thrombocytopenia (49% vs 57%). There were no statistically significant differences in the incidence or grades of adverse events. The clinical benefit response was 53% in the standard group and 62% in the modified group (P = 0.9). The median progression-free survival was 4.2 and 6.5 months (incidence rate ratio, 1.22; 95% confidence interval, 0.71-2.15; P = 0.29), and median overall survival was 6.6 and 8.4 months (incidence rate ratio, 1.83; 95% confidence interval, 1.04-3.35; P = 0.03), in favor of the modified regimen. CONCLUSIONS: Our shorter, within-day regimen for delivering dose-intense weekly cisplatin and oral etoposide to treat platinum-resistant metastatic ovarian cancer is safe and efficacious. PMID- 29466254 TI - Characteristics and Prognosis of Stage I Ovarian Mucinous Tumors According to Expansile or Infiltrative Type. AB - BACKGROUND: The present study retrospectively determined the outcomes and prognoses in stage I mucinous ovarian carcinoma according to histological type (ie, expansile or infiltrative). METHODS: A centralized pathologic review of tumors in patients treated from 1976 to 2016 for ovarian mucinous carcinoma was performed by 2 expert pathologists according to the 2014 World Health Organization classification. Only patients with stage I disease were analyzed. Tumors were typed as expansile or infiltrative and oncological issues analyzed. RESULTS: A total of 114 cases were reviewed. Fifty were excluded (stage > I in 30 cases and no accessibility to a pathological review for 20 cases). Thus, 64 patients fulfilled the inclusion criteria: 29 had expansile-type and 35 infiltrative-type disease. The characteristics of both groups of patients were comparable, except the use of nodal staging surgery, which was more frequent in patients with infiltrative type. The International Federation of Gynecology and Obstetrics stages in expansile and infiltrative types were as follows: IA in 13 (45%) and 20 (57%), and IC in 16 (55%) and 15 (43%), respectively. Recurrence occurred in 3 patients with expansile type and 6 patients with infiltrative type. Two cases of expansile recurrence had pelvic recurrence and were salvaged after secondary surgery and chemotherapy, whereas 5 cases of infiltrative recurrence had extrapelvic spread and died from disease or were alive with progressive disease. CONCLUSIONS: Recurrence occurred in both types of stage I mucinous ovarian cancer. However, lethal recurrences were observed mainly in infiltrative type. PMID- 29466255 TI - Differential Expression of MicroRNAs in Uterine Cervical Cancer and Its Implications in Carcinogenesis; An Integrative Approach. AB - OBJECTIVES: Cervical cancer is the second most common cancer in women in developing countries, including India. Recently, microRNAs (miRNAs) are gaining importance in cancer biology because of their involvement in various cellular processes. The present study aimed to profile miRNA expression pattern in cervical cancer, identify their target genes, and understand their role in carcinogenesis. METHODS: Human papillomavirus (HPV) infection statuses in samples were assessed by heminested polymerase chain reaction followed by direct DNA sequencing. Next-generation sequencing and miRNA microarray were used for miRNA profiling in cervical cancer cell lines and tissue samples, respectively. MicroRNA signature was validated by quantitative real-time PCR, and biological significance was elucidated using various in silico analyses. RESULTS: Cervical cancer tissues samples were mostly infected by HPV type 16 (93%). MicroRNA profiling showed that the pattern of miRNA expression differed with respect to HPV positivity in cervical cancer cell lines. However, target and pathway analyses indicated identical involvement of these significantly deregulated miRNAs in HPV-positive cervical cancer cell lines irrespective of type of HPV infected. Microarray profiling identified a set of miRNAs that are differentially deregulated in cervical cancer tissue samples which were validated using quantitative real-time PCR. In silico analyses revealed that the signature miRNAs are mainly involved in PI3K-Akt and mTOR pathways. CONCLUSIONS: The study identified that high-risk HPV induces similar carcinogenic mechanism irrespective of HPV type. The miRNA signature of cervical cancer and their target genes were also elucidated, thereby providing a better insight into the molecular mechanism underlying cervical cancer development. PMID- 29466256 TI - The Impact of an Enhanced Recovery After Surgery Program on Patients Treated for Gynecologic Cancer in the Community Hospital Setting. AB - OBJECTIVES: The purpose of this study was to compare the outcomes of gynecologic oncology patients treated in the community hospital setting either under the auspices of an enhanced recovery after surgery (ERAS) protocol or in accordance with physician discretion. METHODS: We retrospectively evaluated a series of consecutive gynecologic oncology patients who were managed via open surgery in coincident with an ERAS pathway from January 2015 to December 2016. They were compared with a historical open surgery cohort who was treated from November 2013 to December 2014. The primary clinical end points encompassed hospital length of stay, hospital costs, and patient readmission rates. RESULTS: There were 86 subjects accrued in the ERAS group and 91 patients in the historical cohort. The implementation of ERAS occasioned a greater than 3-day mean reduction in hospital stay (8.04 days for the historical group vs 4.88 days for the ERAS subjects; P = 0.001) and correspondingly diminished hospital costs ($11,877.47/patient vs $9305.26/patient; P = 0.04). Moreover, there were 2 readmissions (2.3%) in the ERAS group compared with 4 (4.4%) in the historical cohort (P = 0.282). CONCLUSIONS: The results from our investigation suggest that adhering to an ERAS protocol confers beneficial hospital length of stay and hospital cost outcomes, without compromising patient readmission rates. Additional investigation scrutinizing the impact of ERAS enactment with more defined study variables in a larger, randomized setting is warranted. PMID- 29466257 TI - Recurrent Cancer Is Associated With Dissatisfaction With Care-A Longitudinal Analysis Among Ovarian and Endometrial Cancer Patients. AB - OBJECTIVE: The primary aim of this study was to assess the longitudinal impact of a recurrence of gynecological cancer on satisfaction with information provision and care. The secondary aim was to assess the impact of a recurrence on illness perceptions, anxiety, and depression and health-related quality of life. METHODS: This study is a longitudinal analysis from the ROGY Care trial, conducted between 2011 and 2014, including patients with endometrial (n = 215) and ovarian (n = 149) cancer. Patients were invited to complete questionnaires directly after initial treatment and after 6, 12, and 24 months. Satisfaction with information provision and care, illness perceptions, anxiety, and depression were compared before and after the recurrence. Linear mixed-model analyses were conducted to assess the differences in outcomes of patients with a recurrence compared with patients without a recurrence. RESULTS: During 2-year follow-up, 25 patients with endometrial cancer (12%) and 64 patients with ovarian cancer (43%) had recurrent disease, of whom 9 endometrial and 26 ovarian cancer patients completed at least 1 questionnaire after their recurrence was determined. Patients reported lower satisfaction with care after the diagnosis of a recurrence (doctor interpersonal skills, exchange of information between caregivers, and general satisfaction with care) compared with patients without recurrence. In addition, patients reported lower health-related quality of life, more anxiety and depression, and more threatening illness perceptions after diagnosis of a recurrence. CONCLUSIONS: After diagnosis of recurrent disease, endometrial and ovarian cancer patients were less satisfied with care compared with patients without a recurrence. Our findings suggest that patients with recurrent cancer are in need of care that is better tailored to their needs. PMID- 29466258 TI - TIME COURSE OF CHANGES IN OPTIC DISK NEOVASCULARIZATION AFTER A SINGLE INTRAVITREAL BEVACIZUMAB INJECTION. AB - PURPOSE: To evaluate the longitudinal changes in optic disk neovascularization (NVD) after intravitreal bevacizumab injection using optical coherence tomography angiography. METHODS: In this prospective, interventional, case series, eyes with NVD secondary to diabetic retinopathy were enrolled. En face optical coherence tomography angiographic images were obtained from the optic disks before and 3 hours, 6 hours, 24 hours, 7 days, and 30 days after intravitreal bevacizumab injection. The size and flow area of the neovascularization were measured by two graders. RESULTS: Eleven eyes of 9 patients with a mean age of 52.11 +/- 9.48 years were included. The reduction in the NVD size and flow area was statistically significant at 24 hours, 7 days, and 30 days after injections compared with the baseline measurements (all P < 0.05). The decremental regression in the NVD size and flow area continued during the study course. The changes were not statistically significant in 3-hour and 6-hour measurements (all P > 0.05). CONCLUSION: In this study, statistically significant regression in the NVD size and flow area was observed as early as 24 hours after a single intravitreal bevacizumab injection, with a continued decreasing trend for at least a 1-month period. PMID- 29466259 TI - An Exploration of Contributing Factors to Patient Safety. AB - One in 3 patients is estimated to experience health care-related harm during hospitalization. This descriptive, cross-sectional study used the Safety Attitudes Questionnaire to measure interprofessional staff perceptions of safety and teamwork climate and a retrospective, modified Global Trigger Tool chart review methodology to measure unit-level patient outcomes. Safety climate and teamwork did not have a statistically significant relationship with the frequency of adverse events identified by the Global Trigger Tool. Researchers may consider the Global Trigger Tool for detecting unit-level adverse events.

AB - The purpose of this quality improvement initiative was to improve oropharyngeal dysphagia screening and reduce aspiration pneumonia rates on 3 inpatient hospital medical units. Guided by a Plan-Do-Study-Act methodology, an interdisciplinary health team developed and implemented a systematic process for oropharyngeal dysphagia screening and management. As a result, use of the screening protocol increased, timely initiation of speech language pathology consultations increased, and aspiration pneumonia rates decreased. PMID- 29466261 TI - Engaging Nurses in Optimizing Antimicrobial Use in ICUs: A Qualitative Study. AB - Antimicrobial stewardship programs (ASPs) have predominately involved infectious diseases physicians and pharmacists with little attention to the nurses. To achieve optimal success of ASPs, engagement of nurses to actively participate in initiatives, strategies, and solutions to combat antibiotic resistance across the health care spectrum is required. In this context, the experiences of local ASP teams engaging nurses in appropriate antimicrobial use were explored to inform future strategies to enhance their involvement in ASPs.

AB - The purpose of this study was to evaluate the occurrence of medication discrepancies during transitional care home visits and the association with emergency department (ED) visits. Using secondary data analysis, the relationships between in-home medication discrepancies and 30- and 90-day ED utilization were examined. For every in-home medication discrepancy, the odds of being admitted to the ED within 90 days increased by 31%. This brief intervention could add a valuable component to post-hospital transition management. PMID- 29466263 TI - Work Intensification and Quality Assurance: Missed Nursing Care. AB - This article examines nurses' commentaries from a survey conducted in New Zealand that studied contradictions between quality assurance and work intensification in nursing care. Nurse managers were blamed for either avoiding or not recognizing work intensification affecting quality care delivery. However, the data illustrate key structural issues resulting in missed care that impact on patient safety, rather than a problem directly attributable to managers. Until these structural issues are addressed, missed care and adverse events will continue to affect the quality of care. PMID- 29466264 TI - Effects of High Sound Exposure During Air-Conducted Vestibular Evoked Myogenic Potential Testing in Children and Young Adults. AB - OBJECTIVES: Vestibular evoked myogenic potential (VEMP) testing is increasingly utilized in pediatric vestibular evaluations due to its diagnostic capability to identify otolith dysfunction and feasibility of testing. However, there is evidence demonstrating that the high-intensity stimulation level required to elicit a reliable VEMP response causes acoustic trauma in adults. Despite utility of VEMP testing in children, similar findings are unknown. It is hypothesized that increased sound exposure may exist in children because differences in ear canal volume (ECV) compared with adults, and the effect of stimulus parameters (e.g., signal duration and intensity) will alter exposure levels delivered to a child's ear. The objectives of this study are to (1) measure peak to peak equivalent sound pressure levels (peSPL) in children with normal hearing (CNH) and young adults with normal hearing (ANH) using high-intensity VEMP stimuli, (2) determine the effect of ECV on peSPL and calculate a safe exposure level for VEMP, and (3) assess whether cochlear changes exist after VEMP exposure. DESIGN: This was a 2-phase approach. Fifteen CNH and 12 ANH participated in phase I. Equivalent ECV was measured. In 1 ear, peSPL was recorded for 5 seconds at 105 to 125 dB SPL, in 5-dB increments for 500- and 750-Hz tone bursts. Recorded peSPL values (accounting for stimulus duration) were then used to calculate safe sound energy exposure values for VEMP testing using the 132-dB recommended energy allowance from the 2003 European Union Guidelines. Fifteen CNH and 10 ANH received cervical and ocular VEMP testing in 1 ear in phase II. Subjects completed tympanometry, pre- and postaudiometric threshold testing, distortion product otoacoustic emissions, and questionnaire addressing subjective otologic symptoms to study the effect of VEMP exposure on cochlear function. RESULTS: (1) In response to high-intensity stimulation levels (e.g., 125 dB SPL), CNH had significantly higher peSPL measurements and smaller ECVs compared with ANH. (2) A significant linear relationship between equivalent ECV (as measured by diagnostic tympanometry) and peSPL exists and has an effect on total sound energy exposure level; based on data from phase I, 120 dB SPL was determined to be an acoustically safe stimulation level for testing in children. (3) Using calculated safe stimulation level for VEMP testing, there were no significant effect of VEMP exposure on cochlear function (as measured by audiometric thresholds, distortion product otoacoustic emission amplitude levels, or subjective symptoms) in CNH and ANH. CONCLUSIONS: peSPL sound recordings in children's ears are significantly higher (~3 dB) than that in adults in response to high-intensity VEMP stimuli that are commonly practiced. Equivalent ECV contributes to peSPL delivered to the ear during VEMP testing and should be considered to determine safe acoustic VEMP stimulus parameters; children with smaller ECVs are at risk for unsafe sound exposure during routine VEMP testing, and stimuli should not exceed 120 dB SPL. Using 120 dB SPL stimulus level for children during VEMP testing yields no change to cochlear function and reliable VEMP responses.

Biomechanical analysis of suspension training push-up. J Strength Cond Res 32(3): 602-609, 2018 The aims of this study were to evaluate the load distribution between upper and lower extremities during suspension training (ST) push-up at different lengths of ST device and to predict useful equations to estimate the training load. After giving informed consent for participation, 25 subjects (17 men and 8 women; age = 28.1 +/- 5.2 years; body mass = 69.4 +/- 14.3 kg; height = 171.6 +/- 11.3 cm; body mass index (BMI) = 23.4 +/- 3.3 kg.m) were involved in the study. Each subject performed 14 static push-ups at 7 different lengths of ST device in 2 different elbow positions. The load distribution between upper and lower extremities was evaluated through a load cell and a force platform, respectively. To evaluate body inclination, all tests were recorded and analyzed through motion analysis software. To estimate the training load, a multilevel model regression (p <= 0.05) was used. Results showed that when the length of the ST device increased, the body inclination decreased, whereas the ground reaction force decreased and the load on the ST device increased. Moreover, when subjects moved from extended to flexed elbow, the ground reaction force decreased and the load on the ST device increased. In the created regression model (intraclass correlation coefficient = 0.24), the reaction force was the dependent variable, whereas the length of the ST device, BMI, and elbow position were the independent variables. The main findings were that the load distribution between upper and lower extremities changes both when modifying the body inclination and the length of the straps. The use of predicted equations could help practitioners to personalize the workouts according to different specific aims by modifying the length of the ST device to guarantee load progression. PMID- 29466265 TI - Characteristics of Real-World Signal to Noise Ratios and Speech Listening Situations of Older Adults With Mild to Moderate Hearing Loss. AB - OBJECTIVES: The first objective was to determine the relationship between speech level, noise level, and signal to noise ratio (SNR), as well as the distribution of SNR, in real-world situations wherein older adults with hearing loss are listening to speech. The second objective was to develop a set of prototype listening situations (PLSs) that describe the speech level, noise level, SNR, availability of visual cues, and locations of speech and noise sources of typical speech listening situations experienced by these individuals. DESIGN: Twenty older adults with mild to moderate hearing loss carried digital recorders for 5 to 6 weeks to record sounds for 10 hours per day. They also repeatedly completed in situ surveys on smartphones several times per day to report the characteristics of their current environments, including the locations of the primary talker (if they were listening to speech) and noise source (if it was noisy) and the availability of visual cues. For surveys where speech listening was indicated, the corresponding audio recording was examined. Speech-plus-noise and noise-only segments were extracted, and the SNR was estimated using a power subtraction technique. SNRs and the associated survey data were subjected to cluster analysis to develop PLSs. RESULTS: The speech level, noise level, and SNR of 894 listening situations were analyzed to address the first objective. Results suggested that as noise levels increased from 40 to 74 dBA, speech levels systematically increased from 60 to 74 dBA, and SNR decreased from 20 to 0 dB. Most SNRs (62.9%) of the collected recordings were between 2 and 14 dB. Very noisy situations that had SNRs below 0 dB comprised 7.5% of the listening situations. To address the second objective, recordings and survey data from 718 observations were analyzed. Cluster analysis suggested that the participants' daily listening situations could be grouped into 12 clusters (i.e., 12 PLSs). The most frequently occurring PLSs were characterized as having the talker in front of the listener with visual cues available, either in quiet or in diffuse noise. The mean speech level of the PLSs that described quiet situations was 62.8 dBA, and the mean SNR of the PLSs that represented noisy environments was 7.4 dB (speech = 67.9 dBA). A subset of observations (n = 280), which was obtained by excluding the data collected from quiet environments, was further used to develop PLSs that represent noisier situations. From this subset, two PLSs were identified. These two PLSs had lower SNRs (mean = 4.2 dB), but the most frequent situations still involved speech from in front of the listener in diffuse noise with visual cues available. CONCLUSIONS: The present study indicated that visual cues and diffuse noise were exceedingly common in real-world speech listening situations, while environments with negative SNRs were relatively rare. The characteristics of speech level, noise level, and SNR, together with the PLS information reported by the present study, can be useful for researchers aiming to design ecologically valid assessment procedures to estimate real-world speech communicative functions for older adults with hearing loss.

AB - Sokmen, B, Witchey, RL, Adams, GM, and Beam, WC. Effects of sprint interval training with active recovery vs. endurance training on aerobic and anaerobic power, muscular strength, and sprint ability. J Strength Cond Res 32(3): 624-631, 2018-This study compared sprint interval training with active recovery (SITAR) to moderate-intensity endurance training (ET) in aerobic and anaerobic power, muscular strength, and sprint time results. Forty-two recreationally active adults were randomly assigned to a SITAR or ET group. Both groups trained 3* per week for 10 weeks at 75% of V[Combining Dot Above]O2max for 30 minutes weeks 1-4, with duration increasing to 35 minutes weeks 5-7 and 40 minutes weeks 8-10. While ET ran on a 400-m track without rest for the full training session, SITAR sprinted until the 200-m mark and recovered with fast walking or light jogging the second 200 m to the finish line in 3* original sprint time. Maximal oxygen consumption (V[Combining Dot Above]O2max), anaerobic treadmill run to exhaustion at 12.5 km.h at 20% incline, isokinetic leg extension and flexion strength at 60 and 300 degrees .s, and 50 m sprint time were determined before and after training. Results showed a significant improvement (p <= 0.05) in absolute and relative V[Combining Dot Above]O2max, anaerobic treadmill run, and sprint time in both groups. Only SITAR showed significant improvements in isokinetic leg extension and flexion at 300 degrees .s and decreases in body mass (p <= 0.05). SITAR also showed significantly greater improvement (p <= 0.05) over ET in anaerobic treadmill run and 50 m sprint time. These data suggest that SITAR is a time-efficient strategy to induce rapid adaptations in V[Combining Dot Above]O2max comparable to ET with added improvements in anaerobic power, isokinetic strength, and sprint time not observed with ET.

Effect of progressive calisthenic push-up training on muscle strength and thickness. J Strength Cond Res 32(3): 651-659, 2018-Calisthenics, a form of resistance training, continue to increase in popularity; however, few studies have examined their effectiveness for muscle strength improvement. The purpose of this study was to determine whether progressive calisthenic push-up training (PUSH) is comparable with traditional bench press training (BENCH) as a technique for increasing muscle strength and thickness. Twenty-three healthy, moderately trained men (mean +/- SD: age 23 +/- 6.8 years) completed the study. Subjects were randomly assigned to PUSH (n = 14) and BENCH (n = 9) groups and were trained 3 days per week for 4 weeks. Muscle thickness (MT), seated medicine ball put (MBP), 1 repetition maximum (1RM) bench press, and push-up progression (PUP) were measured before and after training. Results revealed significant increases in 1RM (p < 0.001) and PUP (p < 0.001) for both groups after training. The increase in PUP was significantly greater for PUSH (p < 0.001). No significant differences were found within groups for MT and MBP (p > 0.05). This study is the first to demonstrate that calisthenics, using different progressive variations to maintain strength training programming variables, can improve upper-body muscle strength.

Neuromuscular effects to 6 weeks of loaded countermovement jumping with traditional and daily undulating periodization. J Strength Cond Res 32(3): 660-674, 2018-Loaded vertical jumps are routinely used to enhance athlete's power production in the lower extremity and to optimize jumping and sprinting performance. This study compared traditional (TP) and daily undulating (DUP) periodization on muscle strength, jumping performance, electromyographic (EMG) muscle activity, and muscle architecture during preseason loaded jump training. Twenty-two athletes from different team sports (age: 24.3 +/- 2.6 years, height: 175.9 +/- 7.5 cm, body mass: 72.2 +/- 8.4 kg, 12 males/10 females, strength training experience: 5.1 +/- 2.2 years) performed 6 weeks of loaded countermovement jumping (CMJ) (18 sessions) during which subjects arranged the experimental training loads with either TP or DUP. Therefore, loading conditions corresponding to 0, 15, and 30% of individual body mass were used by manipulating weighted training vests and the intensity zones and training volume were equated between the groups. Pre- to post-training, center of mass (COM) maximal CMJ performance, isometric maximal voluntary contractive capacity of the leg extensors (MVC), EMG maximal voluntary muscle activity of knee extensor muscles, and vastus lateralis and rectus femoris muscle architecture were examined. Repeated measures multivariate analysis of variances (MANOVA with factors: time * training group) revealed moderate (5-16%) but significant (p <= 0.006) temporal increases in COM jumping height, leg extensor MVC and muscle architecture in both groups. Importantly, these temporal alterations were similar using either TP or DUP. Therefore, our data indicate that both periodization models can be effectively applied to increase leg extensor strength, vertical jumping performance, and muscle architecture during short-term preseason loaded jump training.

Validity and reliability of the load-velocity relationship to predict the 1RM in deadlift. J Strength Cond Res 32(3): 681-689, 2018-The aim of this study was to verify the reliability and validity of using submaximal loads from the load-velocity relationship to predict the actual 1 repetition maximum (1RM) in the deadlift. Data from 11 resistance-trained athletes were analyzed performing three 1RM assessments separated by at least 3 days. Reliability was assessed by comparing predicted 1RMs of sessions 2 and 3, whereas for validity purposes, predicted 1RMs of session 3 were compared with actual 1RMs of session 2. Mean concentric velocity at 1RM (v at 1RM) was entered in individualized linear regression equations, derived from the load-velocity relationship for 3 (20-60%, 40-80%, and 60-90% of 1RM), 4 (20-80% and 40-90% of 1RM), and 5 (20-90% of 1RM) incremental loads to predict 1RMs. There were trivial changes for all predicted 1RMs between sessions with 20-90% of 1RM being the most reliable model. Similarly, the actual 1RM was very stable (effect size [ES] = 0.04, 90% confidence limit [CL] [-0.03 to 0.12], typical error of measurement [TE] = 3.4 kg [2.5-5.4], intraclass coefficient [ICC] = 0.99 [0.96-0.996], and coefficient of variation [CV] = 1.9% [1.4-3.0]), whereas the v at 1RM was unreliable between trials (ES = -0.30, 90% CL [-0.78 to 0.17], TE = 0.029 m.s [0.022-0.047], ICC = 0.63 [0.19-0.86], and CV = 15.7% [11.7-26.1]). However, predicted 1RMs computed from all submaximal load ranges substantially overestimated the actual 1RM with considerable differences between athletes. Although 1RM predictions showed high reliability, they all overestimated the actual 1RM, which was stable between sessions. Therefore, it is not recommended to apply the prediction models used in this study to compute daily 1RMs. PMID- 29466271 TI - The Relationship Between Multidirectional Jumping and Performance in Change of Direction Tasks. AB - Bourgeois, FA II, Gamble, P, Gill, ND, and McGuigan, MR. The relationship between multidirectional jumping and performance in change of direction tasks. J Strength Cond Res 32(3): 690-699, 2018-This study investigated the test-retest reliability of 2 change of direction (COD; 180 and 45 degrees COD) sprints and 3 multidirectional jump (MDJ) tests. Variables examined were approach time (sprint before plant-step), exit time (sprint after plant-step), total time (time to completion) and MDJ approach time, and distance, respectively. Second, the ability of MDJ tests to predict performance in COD tests was examined. Twenty men (age: 27.5 +/- 5.9 years; height: 1.79 +/- 0.1 m; and body mass: 79.1 +/- 12.0 kg) performed 5 trials for each assessment, executing left plant-leg (LT) and right plant-leg (RT) steps, on 2 testing occasions separated by 7 days. Between session and within-session intraclass correlation coefficients (ICCs) and coefficients of variation (CVs) for all measurements were calculated. Usefulness of COD and MDJ tests was assessed using typical error and smallest worthwhile change (SWC) comparison. Results showed only one MDJ measurement generated unstable between-session reliability. Within-session reliability of approach and exit COD times, and MDJ approach times possessed confidence limits (90% CL) that extended below 0.75 ICC. All COD total times and MDJ distances presented high reliability (ICC = 0.87-0.99) with low CV (0.9-4.1%). Right-leg MDJ distances were predictors of RT COD performances (r = 0.50-0.68, p = 0.001-0.024), whereas LT MDJ distances were predictors of LT180 COD performance (r = 0.67-0.71, p = 0.001). All measurements were useful in detecting SWC in performance. These findings suggest the COD tests and MDJ distances are reliable for assessing and monitoring COD performance in similar cohorts.

Is vertical jump height an indicator of athletes' power output in different sports modalities? J Strength Cond Res 32(3): 708-715, 2018-This study aimed to identify whether the ratio standard is adequate for the scaling of peak power output (PPO) for body mass (BM) in athletes of different sports and to verify classification agreement for athletes involved in different sports using PPO scaled for BM and jump height (JH). One hundred and twenty-four male athletes divided into 3 different groups combat sports, team sports, and runners-participated in this study. Participants performed the countermovement jump on a force plate. Peak power output and JH were calculated from the vertical ground reaction force. We found different allometric exponents for each modality, allowing the use of the ratio standard for team sports. For combat sports and runners, the ratio standard was not considered adequate, and therefore, a specific allometric exponent for these 2 groups was found. Significant correlations between adjusted PPO for BM (PPOADJ) and JH were found for all modalities, but it was higher for runners (r = 0.81) than team and combat sports (r = 0.63 and 0.65, respectively). Moderate agreement generated by the PPOADJ and JH was verified in team sports (k = 0.47) and running (k = 0.55) and fair agreement in combat sports (k = 0.29). We conclude that the ratio standard seems to be suitable only for team sports; for runners and combat sports, an allometric model seems adequate. The use of JH as an indicator of power output may be considered reasonable only for runners. PMID- 29466273 TI - Heart Rate Variability During Exercise: A Comparison of Artefact Correction Methods. AB - Giles, DA and Draper, N. Heart rate variability during exercise: a comparison of artefact correction methods. J Strength Cond Res 32(3): 726-735, 2018-There is a need for standard practice in the collection and processing of RR interval data recorded using heart rate monitors (HRMs) in research. This article assessed the validity of RR intervals and heart rate variability (HRV) data obtained using an HRM during incremental exercise and artefact correction methods. Eighteen participants completed an active orthostatic test and incremental running V[Combining Dot Above]O2max test, while simultaneous recordings using a Polar V800 HRM and an electrocardiogram were made. Artefacts were corrected by deletion; degree zero, linear, cubic, and spline interpolation; and Kubios HRV software. Agreement was assessed using percentage bias, effect size (ES), intraclass correlation coefficients (ICC), and Bland-Altman limits of agreement (LoA). Artefacts increased relative to exercise intensity, to a peak of 4.46% during 80-100% V[Combining Dot Above]O2max. Correction of RR intervals was necessary with unacceptably increased bias, LoA, and ES and reduced ICC in all but resting recordings. All correction methods resulted in data with reduced percentage bias and ES for resting and <60% V[Combining Dot Above]O2max recordings. However, at >60% V[Combining Dot Above]O2max, even with correction, large amounts of variation were present in HRV measures of root mean square of the successive difference of intervals, low-to-high frequency ratio, Poincare dispersion perpendicular to the axis (SD1), and sample entropy. Linear interpolation produced RR intervals with the lowest bias and ES. However, caution should be given to HRV parameters at high exercise intensities, as large amounts of variation were still present. Recommendations for minimizing artefacts are discussed, along with guidelines for their identification, correction, and reporting.

Dissociated time course of recovery between strength and power after isoinertial resistance loading in rugby union players. J Strength Cond Res 32(3): 748-755, 2018-There is a substantial amount of research on the responses to isometric and eccentric loading. However, only a paucity of literature exists on the responses to isoinertial loading, especially in trained athletic populations using realistic loading protocols. The purpose of this study was to examine the acute neuromuscular response to a bout of isoinertial resistance loading in elite rugby players. Seventeen male (age: 19.5 +/- 2.3 years) rugby union players performed a conventional maximal isoinertial resistance loading protocol. Countermovement jump (CMJ) and maximal voluntary isometric contraction (MVC) squat performance were measured on 3 occasions: at baseline, immediately post, and 48 hour post. The results indicated that the decrease in MVC (9.7%) is greater than or comparable with the CMJ output variables (4.2-10.3%), immediately postexercise. Although isometric strength had demonstrated a full recovery at 48 hour post, many of the key CMJ output variables were still impaired (p <= 0.05). Similar findings were observed in the normalized CMJ curves. Complete recovery of the ability to rapidly produced force may require more than 48 hours in many athletes. Individual responses should, therefore, be monitored to help plan acute and chronic training loads. It is recommended that future fatigue studies should incorporate temporal phase analyses to consider the power-, force-, velocity-, and displacement-time curves.

Intra-cyclic velocity variation of the center of mass and hip in breaststroke swimming with maximal intensity. J Strength Cond Res 32(3): 830-840, 2018-The aim of the study was to compare the center of mass (CM) and hip (HIP) intracyclic velocity variation in breaststroke swimming using 3-dimensional kinematic analysis. Nine male breaststrokes, of moderate performance level, swam 25-m breaststroke with maximal intensity, and their movements were recorded, both under and above the water surface, using 8 digital cameras. Their CM and HIP velocities and their intracyclic variations were estimated after manual digitization of 28 selected points on the body in a complete arm and leg breaststroke cycle. Paired sample t tests or Wilcoxon tests, when the assumption of normality was broken, were used for statistical analyses. In both, CM and HIP velocity-time curves, the results revealed a similar pattern of 2 clear peaks associated with the leg and arm propulsive phases and 2 minimal velocities that corresponded to the arm and leg recovery phase and the lag time between the leg and arm propulsive phases, respectively. However, despite this similar general pattern, the HIP minimum resultant velocity was significantly lower, whereas its maximal value was significantly greater, than the corresponding CM values. Consequently, the HIP intracyclic swimming velocity fluctuation significantly overestimates the actual variation of the swimmer's velocity in breaststroke swimming. PMID- 29466276 TI - Changes in Energy Demand of Dance Activity and Cardiorespiratory Fitness During 1 Year of Vocational Contemporary Dance Training. AB - Beck, S, Wyon, MA, and Redding, E. Changes in energy demand of dance activity and cardiorespiratory fitness during 1 year of vocational contemporary dance training. J Strength Cond Res 32(3): 841-848, 2018-Previous literature has demonstrated that the intensity of dance class as well as its discontinuous nature is not sufficient to elicit an aerobic training response and that the aerobic capacity of dancers is relatively low. These findings have raised questions on the suitability of training, through class and rehearsal, as adequate preparation for the physical demands of performance and a sustained, successful career in dance. The aim of this study was to describe changes in aerobic fitness and energy cost of dance movement occurring throughout 1 year of training. Subjects were 13 female dance students; 7 first-year undergraduate (UG) students, and 6 postgraduate (PG) students. At 3 time points (TP1, TP2, and TP3) during 1 academic year, each subject completed a treadmill test to determine V[Combining Dot Above]O2peak (ml.kg.min) and lactate threshold (LT) (ml.kg.min and %V[Combining Dot Above]O2peak) and a standardized 4-minute dance sequence, where the mean demand was expressed as V[Combining Dot Above]O2 (ml.kg.min), heart rate (b.min), %V[Combining Dot Above]O2peak, and %LT. Both groups displayed an overall decrease in mean V[Combining Dot Above]O2peak throughout the year, despite a peak in fitness at TP2 in the PG students. No significant changes in LT were noted over time for either group. A significant reduction in the relative intensity of the dance sequence, particularly in relation to mean VO2 (ml.kg.min) and %LT data, was observed over time in both groups, although the degree of change was less in the UG group than the PG group. Apparent adaptations during a rehearsal period in the PG group are presented in contrast to previous research findings. Recommendations for future research include further investigation into the energy demand of rehearsal and cardiorespiratory adaptation during rehearsal periods as well as further reporting of measures related to LT and movement economy.

Optimizing a treadmill ramp protocol to evaluate aerobic capacity of hemiparetic poststroke patients. J Strength Cond Res 32(3): 876-884, 2018-A correct assessment of cardiopulmonary capacity is important for aerobic training within motor rehabilitation of poststroke hemiparetic patients (PSHPs). However, specific cardiopulmonary exercise testing (CPET) for these patients are scarce. We proposed adaptations in a protocol originally developed for PSHPs by Ovando et al. (CPET1). We hypothesized that our adapted protocol (CPET2) would improve the original test, by preventing early fatigue and increasing patients' peak performance. Eleven PSHPs (52 +/- 14 years, 10 men) performed both protocols. CPET2 integrated changes in final speed (100-120% vs. 140% maximal speed in 10-m walking test), treadmill inclination (final inclination of 5 vs. 10%), and estimated test duration (10 vs. 8 minutes) to smooth the rate of workload increment of CPET1. Peak oxygen uptake (V[Combining Dot Above]O2peak) (20.3 +/- 6.1 vs. 18.6 +/- 5.0 ml.kg.min; p = 0.04), V[Combining Dot Above]O2 at gas exchange transition (V[Combining Dot Above]O2-GET) (11.5 +/- 2.9 vs. 9.8 +/- 2.0 ml.kg.min; p = 0.04), and time to exhaustion (10 +/- 3 vs. 6 +/- 2 minutes; p < 0.001) were higher in CPET2 than in CPET1. Slopes and intercepts of regressions describing relationships between V[Combining Dot Above]O2 vs. workload, heart rate vs. workload, and V[Combining Dot Above]O2 vs. heart rate were similar between CPETs. However, standard errors of estimates obtained for regressions between heart rate vs. workload (3.0 +/- 1.3 vs. 3.8 +/- 1.0 b.min; p = 0.004) and V[Combining Dot Above]O2 vs. heart rate (6.0 +/- 2.1 vs. 4.8 +/- 2.4 ml.kg.min; p = 0.05) were lower in CPET2 than in CPET1. In conclusion, the present adaptations in Ovando's CPET protocol increased exercise tolerance of PSHPs, eliciting higher V[Combining Dot Above]O2peak and V[Combining Dot Above]O2 GET, preventing earlier fatigue, and providing better physiological relationships along submaximal workloads.

AB - BACKGROUND: Despite the large body of extant literature on sexually transmitted infections (STIs) in adolescents and young adults (AYAs), more research on social and environmental contextual factors is needed. Also, further examination of STI indicators by gender remains a critical area of research focus. METHODS: Anonymous survey data were collected using audio computer-assisted self interviews in community venues in urban, low-income, STI prevalent, US neighborhoods to reach AYAs, aged 12 to 24 years. Conventional descriptive statistics, bivariate analysis, and multiple logistical regression models were used to assess indicators of a self-reported lifetime prevalence of STIs. RESULTS: Participants (N = 1540) were on average 20.6 years; 57.2% were women, the majority were racial and ethnic minorities (92%), and almost half (49.2%) identified as sexual minorities. Nearly one third (32.%) had 1 or more STIs. As expected, gender differences were identified. For AYA men, being African American/Black, moving residences more than 4 times since kindergarten, and having a history of human immunodeficiency virus testing were each positively associated with STIs. Also, those who strongly disagreed that many young people in their community exchanged sex for money had a significantly lower likelihood of having an STI. For AYA women, exchanging sex for drugs or money, lacking money, which prevented activities, and using marijuana were each associated with STIs. CONCLUSIONS: This research extends our understanding of social and environmental contextual influences on AYAs' risk for STIs. It highlights differences in risk exposures that are distinctly different for AYA women and men, suggesting the need for tailored interventions to address their unique economic needs and social challenges. PMID- 29466280 TI - Persistent injury-associated anemia and aging: Novel insights. AB - BACKGROUND: Hypercatecholaminemia and bone marrow dysfunction have been implicated in the pathophysiology of persistent injury-associated anemia. The elderly may be more vulnerable to bone marrow dysfunction due to high basal and peak catecholamine levels and impaired hematopoietic progenitor growth. We hypothesized that aging would adversely affect persistent injury-associated anemia. METHODS: Male Sprague-Dawley rats aged 8 to 9 weeks and F344-BN rats aged 25 months were randomized to naive controls, lung contusion plus hemorrhagic shock (LCHS), and LCHS plus daily chronic restraint stress (LCHS/CS). Urine norepinephrine was measured on Days 1 and 7. Mobilization of hematopoietic progenitor cells (HPCs), bone marrow colony-forming units-erythroid growth, and peripheral blood hemoglobin, mean corpuscular volume (MCV), and red cell distribution width (RDW) were assessed on Day 7 (*p < 0.05 young vs. aged counterpart by one-way analysis of variance). RESULTS: Aged rats had higher norepinephrine levels at naive baseline (97* vs. 27 ng/mL) and 7 days following LCHS/CS when compared with young (359* vs. 127 ng/mL). Following LCHS/CS, HPC mobilization was greater among young rats when compared with aged (5.4 vs. 2.5%). Colony-forming units-erythroid growth was lower among aged animals for each group (naive: 47* vs. 65; LCHS: 40* vs. 50; LCHS/CS: 38* vs. 44 cells/plate). Aged naive rats had higher initial hemoglobin (15.2* vs. 14.3 g/dL) but lower MCV (48* vs. 59 fL/cell) and larger RDW at baseline and greater differences 7 days after LCHS/CS (MCV: 46* vs. 60 fL/cell; RDW: 17.4* vs. 16.3%). CONCLUSIONS: Compared with young rats, aged rats had less HPC mobilization despite elevated basal and peak norepinephrine. Aged rats were disproportionately affected by impaired hematopoietic progenitor growth and an iron-restricted red blood cell phenotype at baseline, which persisted 7 days after injury. Further research is needed to assess how the clinical approach to persistent injury-associated anemia should differ for elderly trauma patients. PMID- 29466281 TI - Managing Risk Aversion for Low-Carbon Supply Chains with Emission Abatement Outsourcing. AB - Reducing carbon emissions, including emission abatement outsourcing at the supply chain level, is becoming a significant but challenging problem in practice. Confronting this challenge, we therefore break down the practice to focus on a low-carbon supply chain consisting of one supplier, one manufacturer and one third-party emission-reducing contractor. The contractor offers a carbon reduction service to the manufacturer. In view of the increasing proportion of Greenhouse Gases (GHG) emissions and absence of carbon reduction policies in developing countries, we adopt the prospect of consumers' low-carbon preferences to capture the demand sensitivity on carbon emission. By exploiting the Mean Variance (MV) model, we develop a supply chain game model considering risk aversion. Comparing the supply chain performances of the cases under risk neutrality and risk aversion, we investigate the impact of the risk aversion of the supplier and the manufacturer on the low-carbon supply chain performances, respectively. We show that the risk aversion of chain members will not influence the relationship underlain by the profit-sharing contract between the manufacturer and contractor, whereas they may extend the supplier's concerning range. Although the manufacturer's risk aversion has a positive impact on the wholesale price, interestingly, the supplier's impact on the wholesale price is negative. Furthermore, we propose a contract to coordinate the risk-averse low carbon supply chain by tuning the aversion levels of the supplier and the manufacturer, respectively. Through numerical study, we draw on managerial insights for industrial practitioners to adopt a low carbon strategy potentially by managing the risk attitudes along the supply chain channel.

AB - There is evidence that sea buckthorn, as a source of n-3 polyunsaturated fatty acids (n-3 PUFA), possesses health-enhancing properties and may modulate neuroendocrine and immune functions. In the present study, we investigated the effect of sea buckthorn pomace (SBP) supplementation in the diet of growing German Landrace pigs on fatty acids in the blood and hypothalamus, peripheral immune parameters and mRNA expression of corticotropin-releasing hormone (CRH), mineralocorticoid receptor (MR) and glucocorticoid receptor (GR) in the hypothalamus and spleen. Pigs were fed diets supplemented with 12% of dried SBP or 0% SBP (control group) over an intervention period of eight weeks. The fatty acid profiles in blood plasma were significantly affected by SBP supplementation only for C18:2n-6 and n-6/n-3 PUFA ratio compared with the control group. SBP supplementation did not significantly affect the fatty acid concentrations in the hypothalamus. Furthermore, there were no significant differences in mRNA expression of CRH, MR and GR in the hypothalamus or of GR mRNA expression in the spleen. Concerning the immune status, the plasma IgG levels tended to be higher in SBP pigs, whereas the leukocyte distribution, mitogen-stimulated lymphocyte proliferation, and serum IgM levels remained unchanged. In conclusion, the SBP supplementation of the diet only caused moderate effects on fatty acid metabolism, but no significant effects on hypothalamic-pituitary-adrenal (HPA) activity and immunity in growing pigs. It seems that a beneficial effect of dietary n-3 PUFA on health and welfare is more likely to be expected during stressful situations. PMID- 29466284 TI - An Estimate of the Burden of Fungal Disease in Norway. AB - The aim of this study was to examine the burden of fungal disease in Norway, contributing to a worldwide effort to improve awareness of the needs for better diagnosis and treatment of such infections. We used national registers and actual data from the Departments of Microbiology from 2015 and estimated the incidence and/or prevalence of superficial, allergic and invasive fungal disease using published reports on specific populations at risk. One in 6 Norwegians suffered from fungal disease: Superficial skin infections (14.3%: 745,600) and recurrent vulvovaginal candidiasis in fertile women (6%: 43,123) were estimated to be the most frequent infections. Allergic fungal lung disease was estimated in 17,755 patients (341/100,000). Pneumocystis jirovecii was diagnosed in 262 patients (5/100,000), invasive candidiasis in 400 patients (7.7/100,000), invasive aspergillosis in 278 patients (5.3/100,000) and mucormycosis in 7 patients (0.1/100,000). Particular fungal infections from certain geographic areas were not observed. Overall, 1.79% of the population was estimated to be affected by serious fungal infections in Norway in 2015. Even though estimates for invasive infections are small, the gravity of such infections combined with expected demographic changes in the future emphasizes the need for better epidemiological data. PMID- 29466283 TI - The Relationship between Maternal Nutrition during Pregnancy and Offspring Kidney Structure and Function in Humans: A Systematic Review. AB - The intrauterine environment is critical for fetal growth and organ development. Evidence from animal models indicates that the developing kidney is vulnerable to suboptimal maternal nutrition and changes in health status. However, evidence from human studies are yet to be synthesised. Therefore, the aim of the current study was to systematically review current research on the relationship between maternal nutrition during pregnancy and offspring kidney structure and function in humans. A search of five databases identified 9501 articles, of which three experimental and seven observational studies met the inclusion criteria. Nutrients reviewed to date included vitamin A (n = 3), folate and vitamin B12 (n = 2), iron (n = 1), vitamin D (n = 1), total energy (n = 2) and protein (n = 1). Seven studies were assessed as being of "positive" and three of "neutral" quality. A variety of populations were studied, with limited studies investigating maternal nutrition during pregnancy, while measurements of offspring kidney outcomes were diverse across studies. There was a lack of consistency in the timing of follow-up for offspring kidney structure and/or function assessments, thus limiting comparability between studies. Deficiencies in maternal folate, vitamin A, and total energy during pregnancy were associated with detrimental impacts on kidney structure and function, measured by kidney volume, proteinuria, eGFRcystC and mean creatinine clearance in the offspring. Additional experimental and longitudinal prospective studies are warranted to confirm this relationship, especially in Indigenous populations where the risk of renal disease is greater. PMID- 29466285 TI - The Impact of Brain Breaks Classroom-Based Physical Activities on Attitudes toward Physical Activity in Polish School Children in Third to Fifth Grade. AB - The purpose of this study was to examine the effectiveness of the Brain Breaks(r) Physical Activity Solutions in changing attitudes toward physical activity of school children in a community in Poland. In 2015, a sample of 326 pupils aged 9 11 years old from 19 classes at three selected primary schools were randomly assigned to control and experimental groups within the study. During the classes, children in the experimental group performed physical activities two times per day in three to five minutes using Brain Breaks(r) videos for four months, while the control group did not use the videos during the test period. Students' attitudes toward physical activities were assessed before and after the intervention using the "Attitudes toward Physical Activity Scale". Repeated measures of ANOVA were used to examine the change from pre- to post-intervention. Overall, a repeated measures ANOVA indicated time-by-group interaction effects in 'Self-efficacy on learning with video exercises', F(1.32) = 75.28, p = 0.00, eta2 = 0.19. Although the changes are minor, there were benefits of the intervention. It may be concluded that HOPSports Brain Breaks(r) Physical Activity Program contributes to better self-efficacy on learning while using video exercise of primary school children. PMID- 29466286 TI - Free Monoterpene Isomer Profiles of Vitis Vinifera L. cv. White Wines. AB - Monoterpene compounds contribute floral and fruity characters to wine and are desired by grape growers and winemakers for many white wines. However, monoterpene isomers, especially monoterpene enantiomers, have been little explored. It is possible to identify and quantitate 17 monoterpene isomers in 148 varietal wines from eight grape varieties; Chardonnay, Gewurztraminer, Muscat, Pinot gris, Riesling, Sauvignon blanc, Torrontes, and Viognier in two vintages by Headspace solidphase microextraction multidimensional gas chromatography mass spectrometry (HS-SPME-MDGC-MS). Results obtained from general linear models and discriminant analysis showed significant differences for the isomer profiles and enantiomer fractions among the eight grape varieties and four wine styles. The high R2 values from the fitted line show low variation in enantiomeric differences based on variety. These results provide an overview of the monoterpene isomers of wide varietal wines, and support that isomer profiles and enantiomer fractions could differentiate our wines by varietal and wine style. PMID- 29466288 TI - Research on the Transmission Characteristics of Air-Coupled Ultrasound in Double Layered Bonded Structures. AB - The ultrasonic transmission spectrum in a double-layered bonded structure is related closely to its interfacial stiffness. Consequently, researching the regularity of the transmission spectrum is of significant interest in evaluating the integrity of the bonded structure. Based on the spring model and the potential function theory, a theoretical model is developed by the transfer matrix method to predict the transmission spectrum in a double-layered bonded structure. Some shift rules of the transmission peaks are obtained by numerical calculation of this model with different substrates. The results show that the resonant transmission peaks move towards a higher frequency with the increase of the normal interfacial stiffness, and each of them has different movement distances with the increasing interfacial stiffness. Indeed, it is also observed that the movement starting points of these peaks are at the specific frequency at which the thickness of either substrate plate equals an integral multiple of half a wavelength. The results from measuring the bonding specimens, which have different interfacial properties and different substrates in this experiment, are utilized to verify the theoretical analysis. Though the theory of "starting points" is not demonstrated effectively, the shift direction and distance exactly match with the result from the theoretical algorithm. PMID- 29466287 TI - Comparison of Inhibitory Capacities of 6-, 8- and 10-Gingerols/Shogaols on the Canonical NLRP3 Inflammasome-Mediated IL-1beta Secretion. AB - Endogenous noninfectious substances that mediate the nucleotide oligomerization domain (NOD)-like receptor family pyrin domain-containing 3 (NLRP3) inflammasome activation and interleukin (IL)-1beta secretion causes inappropriate sterile inflammation and is implicated in the pathogenesis of several chronic diseases, such as type 2 diabetes mellitus, gout, atherosclerosis and Alzheimer's disease. Consequently, dietary phytochemicals exhibiting capacities to suppress canonical NLRP3 inflammasome-mediated IL-1beta secretion can be a reliable supplement to prevent such diseases. The purpose of this study was to investigate and compare the inhibitory effects of ginger phytochemicals, including 6-, 8- and 10 gingerols/shogaols on the canonical NLRP3 inflammasome-mediated IL-1beta secretion in THP-1 macrophages with ordered stimulations of lipopolysaccharide (LPS) and adenosine 5'-triphosphate (ATP). At 20 MUM, the 10-gingerol and all the shogaols significantly inhibited canonical IL-1beta secretion. The shogaols had a more potent inhibitory capacity than that of corresponding gingerols. Increase of alkyl chain length impacted negatively the inhibitory activity of shogaols. Additionally, these effective ginger phytochemicals not only inhibited the LPS primed expression of pro-IL-1beta and NLRP3, but also decreased ATP-activated caspase-1. The results demonstrated that ginger phytochemicals, especially the most potent, 6-shogaol, might be promising for developing as an inhibitor of the canonical NLRP3 inflammasome-mediated IL-1beta secretion and further applied in prevention of NLRP3 inflammasome-associated diseases. PMID- 29466289 TI - Effects of Sterilization Cycles on PEEK for Medical Device Application. AB - The effects of the sterilization process have been studied on medical grade thermoplastic polyetheretherketone (PEEK). For a reusable medical device, material reliability is an important parameter to decide its lifetime, as it will be subjected to the continuous steam sterilization process. A spring nature, clip component was selected out of a newly designed medical device (patented) to perform this reliability study. This clip component was sterilized for a predetermined number of cycles (2, 4, 6, 8, 10, 20...100) at 121 degrees C for 30 min. A significant decrease of ~20% in the compression force of the spring was observed after 30 cycles, and a ~6% decrease in the lateral dimension of the clip was observed after 50 cycles. No further significant change in the compression force or dimension was observed for the subsequent sterilization cycles. Vickers hardness and differential scanning calorimetry (DSC) techniques were used to characterize the effects of sterilization. DSC results exhibited no significant change in the degree of cure and melting behavior of PEEK before and after the sterilization. Hardness measurement exhibited an increase of ~49% in hardness after just 20 cycles. When an unsterilized sample was heated for repetitive cycles without the presence of moisture (121 degrees C, 10 and 20 cycles), only ~7% of the maximum change in hardness was observed. PMID- 29466290 TI - Different Risk Factors for Very Low Birth Weight, Term-Small-for-Gestational-Age, or Preterm Birth in Japan. AB - From 1985 to 2013, the mean birth weight of infants in Japan decreased from 3120 g to 3000 g, and the low-birth-weight rate among live births increased from 6.3% to 9.6%. No prospective study has elucidated the risk factors for poor fetal growth and preterm birth in recent Japanese parents, such as increased parental age, maternal body figure, assisted reproductive technology (ART), and socioeconomic status. Participants were mother-infant pairs (n = 18,059) enrolled in a prospective birth cohort in Hokkaido, Japan from 2002 to 2013. Parental characteristics were obtained via self-reported questionnaires during pregnancy. Medical records helped identify very-low-birth-weight (VLBW; <1500g), term-small for-gestational-age (term-SGA), and preterm-birth (PTB; <37 weeks) infants. We calculated relative risks (RRs) for PTB, VLBW, and term-SGA birth based on parental characteristics. The prevalence of PTB, VLBW, and term-SGA was 4.5%, 0.4%, and 6.5%, respectively. Aged parents and ART were risk factors for PTB and VLBW. Maternal alcohol drinking during pregnancy increased the risk; a parental educational level of >=16 years reduced risk of term-SGA. Maternal pre-pregnancy BMI of <18.5 kg/m2 increased the risk of PTB and term-SGA. The RR for low BMI was highest among mothers who have low educational level. Among various factors, appropriate nutritional education to maintain normal BMI is important to prevent PTB and term-SGA in Japan. PMID- 29466291 TI - Recommendations and Choices for BRCA Mutation Carriers at Risk for Ovarian Cancer: A Complicated Decision. AB - Current ovarian cancer screening guidelines in high-risk women vary according to different organizations. Risk reducing surgery remains the gold standard for definitive treatment in BRCA mutation carriers, but research advancements have created more short-term options for patients to consider. The decisions involved in how a woman manages her BRCA mutation status can cause a great deal of stress and worry due to the imperfect therapy options. The goal of this review was to critically analyze the screening recommendations and alternative options for high risk ovarian cancer patients and evaluate how these discrepancies and choices affect a woman's management decisions. PMID- 29466293 TI - Comparison of SF6 and CF4 Plasma Treatment for Surface Hydrophobization of PET Polymer. AB - The fluorination of the polymer polyethylene terephthalate in plasma created from SF6 or CF4 gas at various pressures was investigated. The surface was analysed by X-ray photoelectron spectroscopy and water contact angle measurements, whereas the plasma was characterized by optical emission spectroscopy. The extent of the polymer surface fluorination was dependent on the pressure. Up to a threshold pressure, the amount of fluorine on the polymer surface and the surface hydrophobicity were similar, which was explained by the full dissociation of the SF6 and CF4 gases, leading to high concentrations of fluorine radicals in the plasma and thus causing the saturation of the polymer surface with fluorine functional groups. Above the threshold pressure, the amount of fluorine on the polymer surface significantly decreased, whereas the oxygen concentration increased, leading to the formation of the hydrophilic surface. This effect, which was more pronounced for the SF6 plasma, was explained by the electronegativity of both gases. PMID- 29466292 TI - Targeting Leukemia Stem Cells in the Bone Marrow Niche. AB - Abstract: The bone marrow (BM) niche encompasses multiple cells of mesenchymal and hematopoietic origin and represents a unique microenvironment that is poised to maintain hematopoietic stem cells. In addition to its role as a primary lymphoid organ through the support of lymphoid development, the BM hosts various mature lymphoid cell types, including naive T cells, memory T cells and plasma cells, as well as mature myeloid elements such as monocyte/macrophages and neutrophils, all of which are crucially important to control leukemia initiation and progression. The BM niche provides an attractive milieu for tumor cell colonization given its ability to provide signals which accelerate tumor cell proliferation and facilitate tumor cell survival. Cancer stem cells (CSCs) share phenotypic and functional features with normal counterparts from the tissue of origin of the tumor and can self-renew, differentiate and initiate tumor formation. CSCs possess a distinct immunological profile compared with the bulk population of tumor cells and have evolved complex strategies to suppress immune responses through multiple mechanisms, including the release of soluble factors and the over-expression of molecules implicated in cancer immune evasion. This chapter discusses the latest advancements in understanding of the immunological BM niche and highlights current and future immunotherapeutic strategies to target leukemia CSCs and overcome therapeutic resistance in the clinic. PMID- 29466294 TI - Respiratory-gated Proton Beam Therapy for Hepatocellular Carcinoma Adjacent to the Gastrointestinal Tract without Fiducial Markers. AB - The efficacy of proton beam therapy (PBT) for hepatocellular carcinoma (HCC) has been reported, but insertion of fiducial markers in the liver is usually required. We evaluated the efficacy and toxicity of respiratory-gated PBT without fiducial markers for HCC located within 2 cm of the gastrointestinal tract. From March 2011 to December 2015 at our institution, 40 patients were evaluated (median age, 72 years; range, 38-87 years). All patients underwent PBT at a dose of 60 to 80 cobalt gray equivalents (CGE) in 20 to 38 fractions. The median follow-up period was 19.9 months (range, 1.2-72.3 months). The median tumor size was 36.5 mm (range, 11-124 mm). Kaplan-Meier estimates of the 2-year overall survival, progression-free survival, and local tumor control rates were 76%, 60%, and 94%, respectively. One patient (2.5%) developed a grade 3 gastric ulcer and one (2.5%) developed grade 3 ascites retention; none of the remaining patients developed grade >3 toxicities (National Cancer Institute Common Terminology Criteria for Adverse Events ver. 4.0.). This study indicates that PBT without fiducial markers achieves good local control without severe treatment-related toxicity of the gastrointestinal tract for HCC located within 2 cm of the gastrointestinal tract. PMID- 29466295 TI - Can Plant Defence Mechanisms Provide New Approaches for the Sustainable Control of the Two-Spotted Spider Mite Tetranychus urticae? AB - Tetranychus urticae (T. urticae) Koch is a cosmopolitan, polyphagous mite which causes economic losses in both agricultural and ornamental plants. Some traits of T. urticae hamper its management, including a short life cycle, arrhenotokous parthenogenesis, its haplodiploid sex determination system, and its extraordinary ability to adapt to different hosts and environmental conditions. Currently, the use of chemical and biological control are the major control methods used against this mite. In recent years, some studies have focused on plant defence mechanisms against herbivores. Various families of plant compounds (such as flavonoids, glucosinolates, or acyl sugars) have been shown to behave as acaricides. Plants can be induced upon appropriate stimuli to increase their resistance against spider mites. This knowledge, together with the understanding of mechanisms by which T. urticae detoxifies and adapts to pesticides, may complement the control of this pest. Herein, we describe plant volatile compounds (VOCs) with repellent activity, and new findings about defence priming against spider mites, which interfere with the T. urticae performance. The use of VOCs and defence priming can be integrated into current management practices and reduce the damage caused by T. urticae in the field by implementing new, more sustainable crop management tools. PMID- 29466296 TI - Sarcoma Spheroids and Organoids-Promising Tools in the Era of Personalized Medicine. AB - Cancer treatment is rapidly evolving toward personalized medicine, which takes into account the individual molecular and genetic variability of tumors. Sophisticated new in vitro disease models, such as three-dimensional cell cultures, may provide a tool for genetic, epigenetic, biomedical, and pharmacological research, and help determine the most promising individual treatment. Sarcomas, malignant neoplasms originating from mesenchymal cells, may have a multitude of genomic aberrations that give rise to more than 70 different histopathological subtypes. Their low incidence and high level of histopathological heterogeneity have greatly limited progress in their treatment, and trials of clinical sarcoma are less frequent than trials of other carcinomas. The main advantage of 3D cultures from tumor cells or biopsy is that they provide patient-specific models of solid tumors, and they overcome some limitations of traditional 2D monolayer cultures by reflecting cell heterogeneity, native histologic architectures, and cell-extracellular matrix interactions. Recent advances promise that these models can help bridge the gap between preclinical and clinical research by providing a relevant in vitro model of human cancer useful for drug testing and studying metastatic and dormancy mechanisms. However, additional improvements of 3D models are expected in the future, specifically the inclusion of tumor vasculature and the immune system, to enhance their full ability to capture the biological features of native tumors in high-throughput screening. Here, we summarize recent advances and future perspectives of spheroid and organoid in vitro models of rare sarcomas that can be used to investigate individual molecular biology and predict clinical responses. We also highlight how spheroid and organoid culture models could facilitate the personalization of sarcoma treatment, provide specific clinical scenarios, and discuss the relative strengths and limitations of these models. PMID- 29466297 TI - A Metabolomic Approach to Predict Breast Cancer Behavior and Chemotherapy Response. AB - Although the classification of breast carcinomas into molecular or immunohistochemical subtypes has contributed to a better categorization of women into different therapeutic regimens, breast cancer nevertheless still progresses or recurs in a remarkable number of patients. Identifying women who would benefit from chemotherapy could potentially increase treatment effectiveness, which has important implications for long-term survival. Metabolomic analyses of fluids and tissues from cancer patients improve our knowledge of the reprogramming of metabolic pathways involved in resistance to chemotherapy. This review evaluates how recent metabolomic approaches have contributed to understanding the relationship between breast cancer and the acquisition of resistance. We focus on the advantages and challenges of cancer treatment and the use of new strategies in clinical care, which helps us comprehend drug resistance and predict responses to treatment. PMID- 29466298 TI - Expression of Lectins in Heterologous Systems. AB - Lectins are proteins that have the ability to recognize and bind in a reversible and specific way to free carbohydrates or glycoconjugates of cell membranes. For these reasons, they have been extensively used in a wide range of industrial and pharmacological applications. Currently, there is great interest in their production on a large scale. Unfortunately, conventional techniques do not provide the appropriate platform for this purpose and therefore, the heterologous production of lectins in different organisms has become the preferred method in many cases. Such systems have the advantage of providing better yields as well as more homogeneous and better-defined properties for the resultant products. However, an inappropriate choice of the expression system can cause important structural alterations that have repercussions on their biological activity since the specificity may lay in their post-translational processing, which depends largely on the producing organism. The present review aims to examine the most representative studies in the area, exposing the four most frequently used systems (bacteria, yeasts, plants and animal cells), with the intention of providing the necessary information to determine the strategy to follow in each case as well as their respective advantages and disadvantages. PMID- 29466299 TI - Further Theoretical Insight into the Mechanical Properties of Polycaprolactone Loaded with Organic-Inorganic Hybrid Fillers. AB - Experimental/theoretical analyses have already been performed on poly(epsilon caprolactone) (PCL) loaded with organic-inorganic fillers (PCL/TiO2 and PCL/ZrO2) to find a correlation between the results from the small punch test and Young's modulus of the materials. PCL loaded with Ti2 (PCL = 12, TiO2 = 88 wt %) and Zr2 (PCL = 12, ZrO2 = 88 wt %) hybrid fillers showed better performances than those obtained for the other particle composition. In this context, the aim of current research is to provide further insight into the mechanical properties of PCL loaded with sol-gel-synthesized organic-inorganic hybrid fillers for bone tissue engineering. For this reason, theoretical analyses were performed by the finite element method. The results from the small punch test and Young's modulus of the materials were newly correlated. The obtained values of Young's modulus (193 MPa for PCL, 378 MPa for PCL/Ti2 and 415 MPa for PCL/Zr2) were higher than those obtained from a previous theoretical modelling (144 MPa for PCL, 282 MPa for PCL/Ti2 and 310 MPa for PCL/Zr2). This correlation will be an important step for the evaluation of Young's modulus, starting from the small punch test data. PMID- 29466300 TI - Active Prior Tactile Knowledge Transfer for Learning Tactual Properties of New Objects. AB - Reusing the tactile knowledge of some previously-explored objects (prior objects) helps us to easily recognize the tactual properties of new objects. In this paper, we enable a robotic arm equipped with multi-modal artificial skin, like humans, to actively transfer the prior tactile exploratory action experiences when it learns the detailed physical properties of new objects. These experiences, or prior tactile knowledge, are built by the feature observations that the robot perceives from multiple sensory modalities, when it applies the pressing, sliding, and static contact movements on objects with different action parameters. We call our method Active Prior Tactile Knowledge Transfer (APTKT), and systematically evaluated its performance by several experiments. Results show that the robot improved the discrimination accuracy by around 10 % when it used only one training sample with the feature observations of prior objects. By further incorporating the predictions from the observation models of prior objects as auxiliary features, our method improved the discrimination accuracy by over 20 % . The results also show that the proposed method is robust against transferring irrelevant prior tactile knowledge (negative knowledge transfer). PMID- 29466301 TI - Lactomycins A-C, Dephosphorylated Phoslactomycin Derivatives that Inhibit Cathepsin B, from the Marine-derived Streptomyces sp. ACT232. AB - Three new polyketides, lactomycins A (1)-C (3), were isolated from the culture broth of a marine-derived Streptomyces sp. ACT232 as cathepsin B inhibitors. Their structures were determined by a combination of NMR and MS data analyses to be the dephosphorylated derivatives of a phoslactomycin class of metabolites. Lactomycins exhibited cathepsin B inhibitory activity (IC50 0.8 to 4.5 MUg/mL). Even though the biosynthetic gene clusters found in the genome of the current strain have high similarity to those of phoslactomycin, neither phoslactomycins nor leustroducsins were detected by LC-MS analyses of the crude extract. PMID- 29466302 TI - A Hexahomotrioxacalix[3]arene-Based Ditopic Receptor for Alkylammonium Ions Controlled by Ag+ Ions. AB - A receptor cone-1 based on a hexahomotrioxacalix[3]arene bearing three pyridyl groups was successfully synthesized, which has a C3-symmetric conformation and is capable of binding alkylammonium and metal ions simultaneously in a cooperative fashion. It can bind alkylammonium ions through the ?-cavity formed by three aryl rings. This behaviour is consistent with the cone-in/cone-out conformational rearrangement needed to reorganize the cavity for endo-complexation. As a C3 symmetrical pyridyl-substituted calixarene, receptor cone-1 can also bind an Ag+ ion, and the nitrogen atoms are turned towards the inside of the cavity and interact with Ag+. After complexation of tris(2-pyridylamide) derivative receptor cone-1 with Ag+, the original C3-symmetry was retained and higher complexation selectivity for n-BuNH3+ versus t-BuNH3+ was observed. Thus, it is believed that this receptor will have a role to play in the sensing, detection, and recognition of Ag+ and n-BuNH3+ ions. PMID- 29466303 TI - Visualization of MMP-2 Activity Using Dual-Probe Nanoparticles to Detect Potential Metastatic Cancer Cells. AB - Matrix metalloproteinases (MMPs) are a family of zinc-dependent enzymes capable of degrading extracellular matrix components. Previous studies have shown that the upregulation of MMP-2 is closely related to metastatic cancers. While Western blotting, zymography, and Enzyme-Linked Immunosorbent Assays (ELISA) can be used to measure the amount of MMP-2 activity, it is not possible to visualize the dynamic MMP-2 activities of cancer cells using these techniques. In this study, MMP-2-activated poly(lactic-co-glycolic acid) with polyethylenimine (MMP-2-PLGA PEI) nanoparticles were developed to visualize time-dependent MMP-2 activities. The MMP-2-PLGA-PEI nanoparticles contain MMP-2-activated probes that were detectable via fluorescence microscopy only in the presence of MMP-2 activity, while the Rhodamine-based probes in the nanoparticles were used to continuously visualize the location of the nanoparticles. This approach allowed us to visualize MMP-2 activities in cancer cells and their microenvironment. Our results showed that the MMP-2-PLGA-PEI nanoparticles were able to distinguish between MMP-2-positive (HaCat) and MMP-2-negative (MCF-7) cells. While the MMP-2 PLGA-PEI nanoparticles gave fluorescent signals recovered by active recombinant MMP-2, there was no signal recovery in the presence of an MMP-2 inhibitor. In conclusion, MMP-2-PLGA-PEI nanoparticles are an effective tool to visualize dynamic MMP-2 activities of potential metastatic cancer cells.

PMID- 29466305 TI - Identification and Characterization of Phenylpropanoid Biosynthetic Genes and Their Accumulation in Bitter Melon (Momordica charantia). AB - Phenylpropanoids and flavonoids belong to a large group of secondary metabolites, and are considered to have antioxidant activity, which protects the cells against biotic and abiotic stresses. However, the accumulation of phenylpropanoids and flavonoids in bitter melon has rarely been studied. Here, we identify ten putative phenylpropanoid and flavonoid biosynthetic genes in bitter melon. Most genes were highly expressed in leaves and/or flowers. HPLC analysis showed that rutin and epicatechin were the most abundant compounds in bitter melon. Rutin content was the highest in leaves, whereas epicatechin was highly accumulated in flowers and fruits. The accumulation patterns of trans-cinnamic acid, p-coumaric acid, ferulic acid, kaempferol, and rutin coincide with the expression patterns of McPAL, McC4H, McCOMT, McFLS, and Mc3GT, respectively, suggesting that these genes play important roles in phenylpropanoid and flavonoid biosynthesis in bitter melon. In addition, we also investigated the optimum light conditions for enhancing phenylpropanoid and flavonoid biosynthesis and found that blue light was the most effective wavelength for enhanced accumulation of phenylpropanoids and flavonoids in bitter melon.

AB - Field and laboratory experiments were carried out in 2012-2013, aimed at evaluating the influence of new products stimulating plant growth based on amino acids on crop yield, characteristics of grain and content of macro- and micronutrients in winter wheat (Triticum aestivum L.). The tests included two formulations produced in cooperation with INTERMAG Co. (Olkusz, Poland)-AminoPrim and AminoHort, containing 15% and 20% amino acids, respectively, and 0.27% and 2.1% microelements, respectively. Field experiments showed that the application of products based on amino acids influenced the increase of grain yield of winter wheat (5.4% and 11%, respectively, for the application of AminoPrim at a dose 1.0 L/ha and AminoHort at dose 1.25 L/ha) when compared to the control group without biostimulant. Laboratory tests showed an increase of technological characteristics of grain such as ash content, Zeleny sedimentation index and content of protein. The use of the tested preparations at different doses also contributed to the increase of the nutrients content in grains, in particular copper (ranging 31-50%), as well as sodium (35-43%), calcium (4.3-7.9%) and molybdenum (3.9-16%). Biostimulants based on amino acids, tested in the present study, can be recommended for an efficient agricultural production. PMID- 29466307 TI - Distress Responses in a Routine Vaccination Context: Relationships to Early Childhood Mental Health. AB - Social and emotional competencies, such as distress regulation, are established in early childhood and are critical for the development of children's mental health and wellbeing. Routine vaccinations in primary care provide a unique opportunity to relate responses to a universal, relatively standardized, distress regulation paradigm (i.e., pain-related distress) to key developmental outcomes. The current study sought to examine distress regulation during routine vaccination in infancy and preschool as predictors of outcomes related to socioemotional competence in preschool. It was hypothesized that children with poorer distress regulation abilities post-vaccination would have lower socioemotional development. Furthermore, it was hypothesized that insensitive parenting would exacerbate this relationship for children with poor distress regulation abilities. As part of an ongoing longitudinal cohort, 172 parent-child dyads were videotaped during vaccinations in infancy and preschool, and subsequently participated in a full-day psychological assessment in a university lab. Videotapes were coded for child pre-needle distress (baseline distress), immediate post-needle pain-related distress reactivity (immediate distress reactivity), and pain-related distress regulation (distress regulation). Parent sensitivity during the preschool vaccination was also coded. Baseline distress prior to vaccination predicted greater externalizing problems and behavioral symptoms. Parent sensitivity did not moderate the association between any child distress behaviors and socioemotional development indicators. Child distress behaviors prior to injection, regardless of parent behavior, during the vaccination context may provide valuable information to health care professionals about child socioemotional functioning in the behavioral and emotional domains. PMID- 29466308 TI - The Use of Manual Vacuum Aspiration in the Treatment of Incomplete Abortions: A Descriptive Study from Three Public Hospitals in Malawi. AB - Malawi has a high maternal mortality rate, of which unsafe abortion is a major cause. About 140,000 induced abortions are estimated every year, despite there being a restrictive abortion law in place. This leads to complications, such as incomplete abortions, which need to be treated to avoid further harm. Although manual vacuum aspiration (MVA) is a safe and cheap method of evacuating the uterus, the most commonly used method in Malawi is curettage. Medical treatment is used sparingly in the country, and the Ministry of Health has been trying to increase the use of MVA. The aim of this study was to investigate the treatment of incomplete abortions in three public hospitals in Southern Malawi during a three-year period. All medical files from the female/gynecological wards from 2013 to 2015 were reviewed. In total, information on obstetric history, demographics, and treatment were collected from 7270 women who had been treated for incomplete abortions. The overall use of MVA at the three hospitals during the study period was 11.4% (95% CI, 10.7-12.1). However, there was a major increase in MVA application at one District Hospital. Why there was only one successful hospital in this study is unclear, but may be due to more training and dedicated leadership at this particular hospital. Either way, the use of MVA in the treatment of incomplete abortions continues to be low in Malawi, despite recommendations from the World Health Organization (WHO) and the Malawi Ministry of Health. PMID- 29466309 TI - The Interrelationship between Family Violence, Adolescent Violence, and Adolescent Violent Victimization: An Application and Extension of the Cultural Spillover Theory in China. AB - The current study is the first study to emphasize family systems, violent norms, and violent peer association as three domains of the social environment that influence both adolescent violent offending and victimization among Chinese adolescents using a longitudinal sample. Under the framework of cultural spillover theory, the purpose of the current study was to explore how these three factors influenced adolescent violent offending and victimization. A total of 1192 middle and high school students were randomly selected from one of the largest cities in Southwest China. Structural equation model analysis was applied to investigate the direct and indirect effect of violence in the family system on violent offending and victimization. The results indicated that violent offending and victimization overlapped among Chinese adolescents. Violent peer association and acceptance of the violence norm fully mediated the effect of violence in the family system on violent offending, and partially mediated the effect of violence in the family system on violent victimization. In conclusion, adolescents who had experienced violence in their family system were more likely to be exposed to violent peer influences and to accept violent norms, which increased the likelihood of violence perpetration and victimization later in their life. PMID- 29466310 TI - An Optimal Image-Based Method for Identification of Acoustic Emission (AE) Sources in Plate-Like Structures Using a Lead Zirconium Titanate (PZT) Sensor Array. AB - This paper proposes an innovative method for identifying the locations of multiple simultaneous acoustic emission (AE) events in plate-like structures from the view of image processing. By using a linear lead zirconium titanate (PZT) sensor array to record the AE wave signals, a reverse-time frequency-wavenumber (f-k) migration is employed to produce images displaying the locations of AE sources by back-propagating the AE waves. Lamb wave theory is included in the f-k migration to consider the dispersive property of the AE waves. Since the exact occurrence time of the AE events is usually unknown when recording the AE wave signals, a heuristic artificial bee colony (ABC) algorithm combined with an optimal criterion using minimum Shannon entropy is used to find the image with the identified AE source locations and occurrence time that mostly approximate the actual ones. Experimental studies on an aluminum plate with AE events simulated by PZT actuators are performed to validate the applicability and effectiveness of the proposed optimal image-based AE source identification method. PMID- 29466311 TI - mIoT Slice for 5G Systems: Design and Performance Evaluation. AB - Network slicing is a key feature of the upcoming 5G networks allowing the design and deployment of customized communication systems to integrate services provided by vertical industries. In this context, massive Internet of Things (mIoT) is regarded as a compelling use case, both for its relevance from business perspective, and for the technical challenges it poses to network design. With their envisaged massive deployment of devices requiring sporadic connectivity and small data transmission, yet Quality of Service (QoS) constrained, mIoT services will need an ad-hoc end-to-end (E2E) slice, i.e., both access and core network with enhanced Control and User planes (CP/UP). After revising the key requirements of mIoT and identifying major shortcomings of previous generation networks, this paper presents and evaluates an E2E mIoT network slicing solution, featuring a new connectivity model overcoming the load limitations of legacy systems. Unique in its kind, this paper addresses mIoT requirements from an end to-end perspective highlighting and solving, unlike most prior related work, the connectivity challenges posed to the core network. Results demonstrate that the proposed solution, reducing CP signaling and optimizing UP resource utilization, is a suitable candidate for next generation network standards to efficiently handle massive device deployment. PMID- 29466312 TI - Split-Ring Resonator Sensor Penetration Depth Assessment Using In Vivo Microwave Reflectivity and Ultrasound Measurements for Lower Extremity Trauma Rehabilitation. AB - In recent research, microwave sensors have been used to follow up the recovery of lower extremity trauma patients. This is done mainly by monitoring the changes of dielectric properties of lower limb tissues such as skin, fat, muscle, and bone. As part of the characterization of the microwave sensor, it is crucial to assess the signal penetration in in vivo tissues. This work presents a new approach for investigating the penetration depth of planar microwave sensors based on the Split-Ring Resonator in the in vivo context of the femoral area. This approach is based on the optimization of a 3D simulation model using the platform of CST Microwave Studio and consisting of a sensor of the considered type and a multilayered material representing the femoral area. The geometry of the layered material is built based on information from ultrasound images and includes mainly the thicknesses of skin, fat, and muscle tissues. The optimization target is the measured S11 parameters at the sensor connector and the fitting parameters are the permittivity of each layer of the material. Four positions in the femoral area (two at distal and two at thigh) in four volunteers are considered for the in vivo study. The penetration depths are finally calculated with the help of the electric field distribution in simulations of the optimized model for each one of the 16 considered positions. The numerical results show that positions at the thigh contribute the highest penetration values of up to 17.5 mm. This finding has a high significance in planning in vitro penetration depth measurements and other tests that are going to be performed in the future. PMID- 29466313 TI - Uncertainly Analysis of Two Types of Humidity Sensors by a Humidity Generator with a Divided-Flow System. AB - Humidity measurement is an important technique for the agricultural, foods, pharmaceuticals, and chemical industries. For the sake of convenience, electrical relative humidity (RH) sensors have been widely used. These sensors need to be calibrated to ensure their accuracy and the uncertainty measurement of these sensors has become a major concern. In this study, a self-made divided-flow generator was established to calibrate two types of electrical humidity sensors. The standard reference humidity was calculated from dew-point temperature and air dry-bulb temperature measured by a chilled mirror monitor. This divided-flow generator could produce consistent result of RH measurement results. The uncertainty of the reference standard increased with the increase of RH values. The combined uncertainty with the adequate calibration equations were ranged from 0.82% to 1.45% RH for resistive humidity sensors and 0.63% to 1.4% for capacitive humidity sensors, respectively. This self-made, divided-flow generator, and calibration method are cheap, time-saving, and easy to be used. Thus, the proposed approach can easily be applied in research laboratories. PMID- 29466314 TI - Sensor Compromise Detection in Multiple-Target Tracking Systems. AB - Tracking multiple targets using a single estimator is a problem that is commonly approached within a trusted framework. There are many weaknesses that an adversary can exploit if it gains control over the sensors. Because the number of targets that the estimator has to track is not known with anticipation, an adversary could cause a loss of information or a degradation in the tracking precision. Other concerns include the introduction of false targets, which would result in a waste of computational and material resources, depending on the application. In this work, we study the problem of detecting compromised or faulty sensors in a multiple-target tracker, starting with the single-sensor case and then considering the multiple-sensor scenario. We propose an algorithm to detect a variety of attacks in the multiple-sensor case, via the application of finite set statistics (FISST), one-class classifiers and hypothesis testing using nonparametric techniques. PMID- 29466315 TI - Robust Rate Maximization for Heterogeneous Wireless Networks under Channel Uncertainties. AB - Heterogeneous wireless networks are a promising technology in next generation wireless communication networks, which has been shown to efficiently reduce the blind area of mobile communication and improve network coverage compared with the traditional wireless communication networks. In this paper, a robust power allocation problem for a two-tier heterogeneous wireless networks is formulated based on orthogonal frequency-division multiplexing technology. Under the consideration of imperfect channel state information (CSI), the robust sum-rate maximization problem is built while avoiding sever cross-tier interference to macrocell user and maintaining the minimum rate requirement of each femtocell user. To be practical, both of channel estimation errors from the femtocells to the macrocell and link uncertainties of each femtocell user are simultaneously considered in terms of outage probabilities of users. The optimization problem is analyzed under no CSI feedback with some cumulative distribution function and partial CSI with Gaussian distribution of channel estimation error. The robust optimization problem is converted into the convex optimization problem which is solved by using Lagrange dual theory and subgradient algorithm. Simulation results demonstrate the effectiveness of the proposed algorithm by the impact of channel uncertainties on the system performance. PMID- 29466316 TI - Approach for the Development of a Framework for the Identification of Activities of Daily Living Using Sensors in Mobile Devices. AB - Sensors available on mobile devices allow the automatic identification of Activities of Daily Living (ADL). This paper describes an approach for the creation of a framework for the identification of ADL, taking into account several concepts, including data acquisition, data processing, data fusion, and pattern recognition. These concepts can be mapped onto different modules of the framework. The proposed framework should perform the identification of ADL without Internet connection, performing these tasks locally on the mobile device, taking in account the hardware and software limitations of these devices. The main purpose of this paper is to present a new approach for the creation of a framework for the recognition of ADL, analyzing the allowed sensors available in the mobile devices, and the existing methods available in the literature. PMID- 29466317 TI - Inhibitory Effects of a Variety of Aldehydes on Amaranthus tricolor L. and Echinochloa crus-galli (L.) Beauv. AB - Thirty-seven commercial aldehydes containing aliphatic chains and aromatic rings as well as heteroaromatic rings were evaluated for their inhibitory activities against Chinese amaranth (Amaranthus tricolor L.) and barnyardgrass (Echinochloa crus-galli (L.) Beauv). Polysorbate 80 (Tween(r) 80) was used as a surfactant and the research was preliminarily conducted at 400 MUM of all aldehydes. Among these aldehydes, (E)-cinnamaldehyde (7) showed the greatest inhibitory effect on seed germination, shoot and root growth of Chinese amaranth by 54.55%, 75.53%, and 85.13% respectively. Similarly, (E)-crotonaldehyde (5), a related alpha,beta unsaturated aldehyde, inhibited the germination and seedling growth of the tested species at a high percentage. Apart from these two unsaturated aldehydes, no other aliphatic aldehydes had a harmful effect on Chinese amaranth. In terms of benzaldehyde (6), it had no effect on the tested plant; however, many of its derivatives displayed some inhibitory activity. Furthermore, for the ten common heteroaromatic aldehydes, picolinaldehyde (32) had a high inhibitory effect on Chinese amaranth which closely related to the effect of (E)-crotonaldehyde (5) and (E)-cinnamaldehyde (7), whereas, other heteroaromatic aldehydes showed lower effects. In the case of a monocot plant, barnyardgrass, no tested aldehydes reduced seed germination, however, (E)-cinnamaldehyde (7), 2,4,6 trimethoxybenzaldehyde (16) and 4-(dimethylamino)benzaldehyde (24) could inhibit the seedling growth of the plant with low to moderate levels. The herbicidal effects of the most active aldehydes were then further investigated in order to find the minimum concentration of these aldehydes suppressing the germination and growth of the tested plants. At concentrations as low as 50-100 MUM some aldehydes could inhibit the seedling growth of the tested species. The structure activity relationship (SAR) study reported here demonstrates the chemical clues governing the inhibitory activity of aldehydes which could be utilized in the development of highly effective herbicides in the near future. PMID- 29466318 TI - Biofilm Formation by the Acidophile Bacterium Acidithiobacillus thiooxidans Involves c-di-GMP Pathway and Pel exopolysaccharide. AB - Acidophile bacteria belonging to the Acidithiobacillus genus are pivotal players for the bioleaching of metallic values such as copper. Cell adherence to ores and biofilm formation, mediated by the production of extracellular polymeric substances, strongly favors bioleaching activity. In recent years, the second messenger cyclic diguanylate (c-di-GMP) has emerged as a central regulator for biofilm formation in bacteria. C-di-GMP pathways have been reported in different Acidithiobacillus species; however, c-di-GMP effectors and signal transduction networks are still largely uncharacterized in these extremophile species. Here we investigated Pel exopolysaccharide and its role in biofilm formation by sulfur oxidizing species Acidithiobacillusthiooxidans. We identified 39 open reading frames (ORFs) encoding proteins involved in c-di-GMP metabolism and signal transduction, including the c-di-GMP effector protein PelD, a structural component of the biosynthesis apparatus for Pel exopolysaccharide production. We found that intracellular c-di-GMP concentrations and transcription levels of pel genes were higher in At. thiooxidans biofilm cells compared to planktonic ones. By developing an At. thiooxidans DeltapelD null-mutant strain we revealed that Pel exopolysaccharide is involved in biofilm structure and development. Further studies are still necessary to understand how Pel biosynthesis is regulated in Acidithiobacillus species, nevertheless these results represent the first characterization of a c-di-GMP effector protein involved in biofilm formation by acidophile species. PMID- 29466319 TI - Skin-on-a-Chip: Transepithelial Electrical Resistance and Extracellular Acidification Measurements through an Automated Air-Liquid Interface. AB - Skin is a critical organ that plays a crucial role in defending the internal organs of the body. For this reason, extensive work has gone into creating artificial models of the epidermis for in vitro skin toxicity tests. These tissue models, called reconstructed human epidermis (RhE), are used by researchers in the pharmaceutical, cosmetic, and environmental arenas to evaluate skin toxicity upon exposure to xenobiotics. Here, we present a label-free solution that leverages the use of the intelligent mobile lab for in vitro diagnostics (IMOLA IVD), a noninvasive, sensor-based platform, to monitor the transepithelial electrical resistance (TEER) of RhE models and adherent cells cultured on porous membrane inserts. Murine fibroblasts cultured on polycarbonate membranes were first used as a test model to optimize procedures using a custom BioChip encapsulation design, as well as dual fluidic configurations, for continuous and automated perfusion of membrane-bound cultures. Extracellular acidification rate (EAR) and TEER of membrane-bound L929 cells were monitored. The developed protocol was then used to monitor the TEER of MatTek EpiDermTM RhE models over a period of 48 hours. TEER and EAR measurements demonstrated that the designed system is capable of maintaining stable cultures on the chip, monitoring metabolic parameters, and revealing tissue breakdown over time. PMID- 29466320 TI - Dynamin-Related Protein 1 at the Crossroads of Cancer. AB - Mitochondrial dynamics are known to have an important role in so-called age related diseases, including cancer. Mitochondria is an organelle involved in many key cellular functions and responds to physiologic or stress stimuli by adapting its structure and function. Perhaps the most important structural changes involve mitochondrial dynamics (fission and fusion), which occur in normal cells as well as in cells under dysregulation, such as cancer cells. Dynamin-related protein 1 (DRP1), a member of the dynamin family of guanosine triphosphatases (GTPases), is the key component of mitochondrial fission machinery. Dynamin-related protein 1 is associated with different cell processes such as apoptosis, mitochondrial biogenesis, mitophagy, metabolism, and cell proliferation, differentiation, and transformation. The role of DRP1 in tumorigenesis may seem to be paradoxical, since mitochondrial fission is a key mediator of two very different processes, cellular apoptosis and cell mitosis. Dynamin-related protein 1 has been associated with the development of distinct human cancers, including changes in mitochondrial energetics and cellular metabolism, cell proliferation, and stem cell maintenance, invasion, and promotion of metastases. However, the underlying mechanism for this association is still being explored. Herein, we review the published knowledge on the role of DRP1 in cancer, exploring its interaction with different biological processes in the tumorigenesis context. PMID- 29466322 TI - Environmental Temperature Controls Accumulation of Transacting siRNAs Involved in Heterochromatin Formation. AB - Genes or alleles can interact by small RNAs in a homology dependent manner meaning that short interfering (siRNAs) can act in trans at the chromatin level producing stable and heritable silencing phenotypes. Because of the puzzling data on endogenous paramutations, their impact contributing to adaptive evolution in a Lamarckian manner remains unknown. An increasing number of studies characterizes the underlying siRNA accumulation pathways using transgene experiments. Also in the ciliate Paramecium tetraurelia, we induce trans silencing on the chromatin level by injection of truncated transgenes. Here, we characterize the efficiency of this mechanism at different temperatures showing that silencing of the endogenous genes is temperature dependent. Analyzing different transgene constructs at different copy numbers, we dissected whether silencing efficiency is due to varying precursor RNAs or siRNA accumulation. Our data shows that silencing efficiency correlates with more efficient accumulation of primary siRNAs at higher temperatures rather than higher expression of precursor RNAs. Due to higher primary levels, secondary siRNAs also show temperature dependency and interestingly increase their relative proportion to primary siRNAs. Our data shows that efficient trans silencing on the chromatin level in P. tetraurelia depends on environmental parameters, thus being an important epigenetic factor limiting regulatory effects of siRNAs. PMID- 29466321 TI - In a quest for engineering acidophiles for biomining applications: challenges and opportunities. AB - Biomining with acidophilic microorganisms has been used at commercial scale for the extraction of metals from various sulfide ores. With metal demand and energy prices on the rise and the concurrent decline in quality and availability of mineral resources, there is an increasing interest in applying biomining technology, in particular for leaching metals from low grade minerals and wastes. However, bioprocessing is often hampered by the presence of inhibitory compounds that originate from complex ores. Synthetic biology could provide tools to improve the tolerance of biomining microbes to various stress factors that are present in biomining environments, which would ultimately increase bioleaching efficiency. This paper reviews the state-of-the-art tools to genetically modify acidophilic biomining microorganisms and the limitations of these tools. The first part of this review discusses resilience pathways that can be engineered in acidophiles to enhance their robustness and tolerance in harsh environments that prevail in bioleaching. The second part of the paper reviews the efforts that have been carried out towards engineering robust microorganisms and developing metabolic modelling tools. Novel synthetic biology tools have the potential to transform the biomining industry and facilitate the extraction of value from ores and wastes that cannot be processed with existing biomining microorganisms. PMID- 29466323 TI - Transplantation of Recombinant Vascular Endothelial Growth Factor (VEGF)189 Neural Stem Cells Downregulates Transient Receptor Potential Vanilloid 1 (TRPV1) and Improves Motor Outcome in Spinal Cord Injury. AB - BACKGROUND Spinal cord injury (SCI) causes a rapid loss of motor neurons, leading to weakness and paralysis. Transplantation of neural stem cells is known to restore the neuronal activity but is inefficient due to limited regenerative capability and low rate of survival. There has been an emphasis on the use of growth factors along with neural stem cells (NSCs) to enhance the neuronal recovery. Transplantation of recombinant NSCs with vascular endothelial growth factor (VEGF) might promote neuronal repair. This effect might be attributed to the reduced transient receptor potential vanilloid 1 (TRPV1) expression following transplantation. MATERIAL AND METHODS NSCs were cultured from the embryos of Sprague-Dawley rats (E12.5). Four group of rats (n=10, each) were subjected to SCI and allowed to recover for 1 week. Recombinant VEGF-NSCs, normal NSCs and PBS were intrathecally administered to the rats. VEGF and TRPV-1 expression at mRNA and protein level was evaluated. ELISA was performed to determine the release of neurotrophic factors after the transplantation. Motor neurons and axons were counted and the motor behavioral outcome was assessed using the rota-rod test. RESULTS VEGF-NSC transgene transplantation resulted in an enhanced neuronal repair and motor behavioral outcome compared to the normal NSCs transplanted group. VEGF-NSCs increased the release of neurotrophic factors and reduced the expression of TRPV1. CONCLUSIONS Recombinant VEGF-NSCs transplantation following SCI is more efficacious compared to normal NSC transplantation. This might also be related to a reduced pain in the process of recovery due to reduced TRPV1 expression. PMID- 29466324 TI - Sequences enriched in Alu repeats drive nuclear localization of long RNAs in human cells. AB - Long noncoding RNAs (lncRNAs) are emerging as key parts of multiple cellular pathways, but their modes of action and how these are dictated by sequence remain unclear. lncRNAs tend to be enriched in the nuclear fraction, whereas most mRNAs are overtly cytoplasmic, although several studies have found that hundreds of mRNAs in various cell types are retained in the nucleus. It is thus conceivable that some mechanisms that promote nuclear enrichment are shared between lncRNAs and mRNAs. Here, to identify elements in lncRNAs and mRNAs that can force nuclear localization, we screened libraries of short fragments tiled across nuclear RNAs, which were cloned into the untranslated regions of an efficiently exported mRNA. The screen identified a short sequence derived from Alu elements and bound by HNRNPK that increased nuclear accumulation. Binding of HNRNPK to C-rich motifs outside Alu elements is also associated with nuclear enrichment in both lncRNAs and mRNAs, and this mechanism is conserved across species. Our results thus identify a pathway for regulation of RNA accumulation and subcellular localization that has been co-opted to regulate the fate of transcripts with integrated Alu elements. PMID- 29466325 TI - Electromechanical vortex filaments during cardiac fibrillation. AB - The self-organized dynamics of vortex-like rotating waves, which are also known as scroll waves, are the basis of the formation of complex spatiotemporal patterns in many excitable chemical and biological systems. In the heart, filament-like phase singularities that are associated with three-dimensional scroll waves are considered to be the organizing centres of life-threatening cardiac arrhythmias. The mechanisms that underlie the onset, maintenance and control of electromechanical turbulence in the heart are inherently three dimensional phenomena. However, it has not previously been possible to visualize the three-dimensional spatiotemporal dynamics of scroll waves inside cardiac tissues. Here we show that three-dimensional mechanical scroll waves and filament like phase singularities can be observed deep inside the contracting heart wall using high-resolution four-dimensional ultrasound-based strain imaging. We found that mechanical phase singularities co-exist with electrical phase singularities during cardiac fibrillation. We investigated the dynamics of electrical and mechanical phase singularities by simultaneously measuring the membrane potential, intracellular calcium concentration and mechanical contractions of the heart. We show that cardiac fibrillation can be characterized using the three dimensional spatiotemporal dynamics of mechanical phase singularities, which arise inside the fibrillating contracting ventricular wall. We demonstrate that electrical and mechanical phase singularities show complex interactions and we characterize their dynamics in terms of trajectories, topological charge and lifetime. We anticipate that our findings will provide novel perspectives for non invasive diagnostic imaging and therapeutic applications. PMID- 29466326 TI - Structure of the D2 dopamine receptor bound to the atypical antipsychotic drug risperidone. AB - Dopamine is a neurotransmitter that has been implicated in processes as diverse as reward, addiction, control of coordinated movement, metabolism and hormonal secretion. Correspondingly, dysregulation of the dopaminergic system has been implicated in diseases such as schizophrenia, Parkinson's disease, depression, attention deficit hyperactivity disorder, and nausea and vomiting. The actions of dopamine are mediated by a family of five G-protein-coupled receptors. The D2 dopamine receptor (DRD2) is the primary target for both typical and atypical antipsychotic drugs, and for drugs used to treat Parkinson's disease. Unfortunately, many drugs that target DRD2 cause serious and potentially life threatening side effects due to promiscuous activities against related receptors. Accordingly, a molecular understanding of the structure and function of DRD2 could provide a template for the design of safer and more effective medications. Here we report the crystal structure of DRD2 in complex with the widely prescribed atypical antipsychotic drug risperidone. The DRD2-risperidone structure reveals an unexpected mode of antipsychotic drug binding to dopamine receptors, and highlights structural determinants that are essential for the actions of risperidone and related drugs at DRD2. PMID- 29466328 TI - Probing the interatomic potential of solids with strong-field nonlinear phononics. AB - Nonlinear optical techniques at visible frequencies have long been applied to condensed matter spectroscopy. However, because many important excitations of solids are found at low energies, much can be gained from the extension of nonlinear optics to mid-infrared and terahertz frequencies. For example, the nonlinear excitation of lattice vibrations has enabled the dynamic control of material functions. So far it has only been possible to exploit second-order phonon nonlinearities at terahertz field strengths near one million volts per centimetre. Here we achieve an order-of-magnitude increase in field strength and explore higher-order phonon nonlinearities. We excite up to five harmonics of the A1 (transverse optical) phonon mode in the ferroelectric material lithium niobate. By using ultrashort mid-infrared laser pulses to drive the atoms far from their equilibrium positions, and measuring the large-amplitude atomic trajectories, we can sample the interatomic potential of lithium niobate, providing a benchmark for ab initio calculations for the material. Tomography of the energy surface by high-order nonlinear phononics could benefit many aspects of materials research, including the study of classical and quantum phase transitions. PMID- 29466327 TI - The atomic structure of a eukaryotic oligosaccharyltransferase complex. AB - N-glycosylation is a ubiquitous modification of eukaryotic secretory and membrane bound proteins; about 90% of glycoproteins are N-glycosylated. The reaction is catalysed by an eight-protein oligosaccharyltransferase (OST) complex that is embedded in the endoplasmic reticulum membrane. Our understanding of eukaryotic protein N-glycosylation has been limited owing to the lack of high-resolution structures. Here we report a 3.5 A resolution cryo-electron microscopy structure of the Saccharomyces cerevisiae OST complex, revealing the structures of subunits Ost1-Ost5, Stt3, Wbp1 and Swp1. We found that seven phospholipids mediate many of the inter-subunit interactions, and an Stt3 N-glycan mediates interactions with Wbp1 and Swp1 in the lumen. Ost3 was found to mediate the OST-Sec61 translocon interface, funnelling the acceptor peptide towards the OST catalytic site as the nascent peptide emerges from the translocon. The structure provides insights into co-translational protein N-glycosylation, and may facilitate the development of small-molecule inhibitors that target this process. PMID- 29466329 TI - Circadian clock neurons constantly monitor environmental temperature to set sleep timing. AB - Circadian clocks coordinate behaviour, physiology and metabolism with Earth's diurnal cycle. These clocks entrain to both light and temperature cycles, and daily environmental temperature oscillations probably contribute to human sleep patterns. However, the neural mechanisms through which circadian clocks monitor environmental temperature and modulate behaviour remain poorly understood. Here we elucidate how the circadian clock neuron network of Drosophila melanogaster processes changes in environmental temperature. In vivo calcium-imaging techniques demonstrate that the posterior dorsal neurons 1 (DN1ps), which are a discrete subset of sleep-promoting clock neurons, constantly monitor modest changes in environmental temperature. We find that these neurons are acutely inhibited by heating and excited by cooling; this is an unexpected result when considering the strong correlation between temperature and light, and the fact that light excites clock neurons. We demonstrate that the DN1ps rely on peripheral thermoreceptors located in the chordotonal organs and the aristae. We also show that the DN1ps and their thermosensory inputs are required for the normal timing of sleep in the presence of naturalistic temperature cycles. These results identify the DN1ps as a major gateway for temperature sensation into the circadian neural network, which continuously integrates temperature changes to coordinate the timing of sleep and activity. PMID- 29466331 TI - Evolutionary history resolves global organization of root functional traits. AB - Plant roots have greatly diversified in form and function since the emergence of the first land plants, but the global organization of functional traits in roots remains poorly understood. Here we analyse a global dataset of 10 functionally important root traits in metabolically active first-order roots, collected from 369 species distributed across the natural plant communities of 7 biomes. Our results identify a high degree of organization of root traits across species and biomes, and reveal a pattern that differs from expectations based on previous studies of leaf traits. Root diameter exerts the strongest influence on root trait variation across plant species, growth forms and biomes. Our analysis suggests that plants have evolved thinner roots since they first emerged in land ecosystems, which has enabled them to markedly improve their efficiency of soil exploration per unit of carbon invested and to reduce their dependence on symbiotic mycorrhizal fungi. We also found that diversity in root morphological traits is greatest in the tropics, where plant diversity is highest and many ancestral phylogenetic groups are preserved. Diversity in root morphology declines sharply across the sequence of tropical, temperate and desert biomes, presumably owing to changes in resource supply caused by seasonally inhospitable abiotic conditions. Our results suggest that root traits have evolved along a spectrum bounded by two contrasting strategies of root life: an ancestral 'conservative' strategy in which plants with thick roots depend on symbiosis with mycorrhizal fungi for soil resources and a more-derived 'opportunistic' strategy in which thin roots enable plants to more efficiently leverage photosynthetic carbon for soil exploration. These findings imply that innovations of belowground traits have had an important role in preparing plants to colonize new habitats, and in generating biodiversity within and across biomes.

AB - The class B glucagon-like peptide-1 (GLP-1) G protein-coupled receptor is a major target for the treatment of type 2 diabetes and obesity. Endogenous and mimetic GLP-1 peptides exhibit biased agonism-a difference in functional selectivity-that may provide improved therapeutic outcomes. Here we describe the structure of the human GLP-1 receptor in complex with the G protein-biased peptide exendin-P5 and a Galphas heterotrimer, determined at a global resolution of 3.3 A. At the extracellular surface, the organization of extracellular loop 3 and proximal transmembrane segments differs between our exendin-P5-bound structure and previous GLP-1-bound GLP-1 receptor structure. At the intracellular face, there was a six-degree difference in the angle of the Galphas-alpha5 helix engagement between structures, which was propagated across the G protein heterotrimer. In addition, the structures differed in the rate and extent of conformational reorganization of the Galphas protein. Our structure provides insights into the molecular basis of biased agonism.

AB - Farming was first introduced to Europe in the mid-seventh millennium bc, and was associated with migrants from Anatolia who settled in the southeast before spreading throughout Europe. Here, to understand the dynamics of this process, we analysed genome-wide ancient DNA data from 225 individuals who lived in southeastern Europe and surrounding regions between 12000 and 500 bc. We document a west-east cline of ancestry in indigenous hunter-gatherers and, in eastern Europe, the early stages in the formation of Bronze Age steppe ancestry. We show that the first farmers of northern and western Europe dispersed through southeastern Europe with limited hunter-gatherer admixture, but that some early groups in the southeast mixed extensively with hunter-gatherers without the sex biased admixture that prevailed later in the north and west. We also show that southeastern Europe continued to be a nexus between east and west after the arrival of farmers, with intermittent genetic contact with steppe populations occurring up to 2,000 years earlier than the migrations from the steppe that ultimately replaced much of the population of northern Europe. PMID- 29466333 TI - The cryo-electron microscopy structure of huntingtin. AB - Huntingtin (HTT) is a large (348 kDa) protein that is essential for embryonic development and is involved in diverse cellular activities such as vesicular transport, endocytosis, autophagy and the regulation of transcription. Although an integrative understanding of the biological functions of HTT is lacking, the large number of identified HTT interactors suggests that it serves as a protein protein interaction hub. Furthermore, Huntington's disease is caused by a mutation in the HTT gene, resulting in a pathogenic expansion of a polyglutamine repeat at the amino terminus of HTT. However, only limited structural information regarding HTT is currently available. Here we use cryo-electron microscopy to determine the structure of full-length human HTT in a complex with HTT-associated protein 40 (HAP40; encoded by three F8A genes in humans) to an overall resolution of 4 A. HTT is largely alpha-helical and consists of three major domains. The amino- and carboxy-terminal domains contain multiple HEAT (huntingtin, elongation factor 3, protein phosphatase 2A and lipid kinase TOR) repeats arranged in a solenoid fashion. These domains are connected by a smaller bridge domain containing different types of tandem repeats. HAP40 is also largely alpha-helical and has a tetratricopeptide repeat-like organization. HAP40 binds in a cleft and contacts the three HTT domains by hydrophobic and electrostatic interactions, thereby stabilizing the conformation of HTT. These data rationalize previous biochemical results and pave the way for improved understanding of the diverse cellular functions of HTT.

AB - Skin-like electronics that can adhere seamlessly to human skin or within the body are highly desirable for applications such as health monitoring, medical treatment, medical implants and biological studies, and for technologies that include human-machine interfaces, soft robotics and augmented reality. Rendering such electronics soft and stretchable-like human skin-would make them more comfortable to wear, and, through increased contact area, would greatly enhance the fidelity of signals acquired from the skin. Structural engineering of rigid inorganic and organic devices has enabled circuit-level stretchability, but this requires sophisticated fabrication techniques and usually suffers from reduced densities of devices within an array. We reasoned that the desired parameters, such as higher mechanical deformability and robustness, improved skin compatibility and higher device density, could be provided by using intrinsically stretchable polymer materials instead. However, the production of intrinsically stretchable materials and devices is still largely in its infancy: such materials have been reported, but functional, intrinsically stretchable electronics have yet to be demonstrated owing to the lack of a scalable fabrication technology. Here we describe a fabrication process that enables high yield and uniformity from a variety of intrinsically stretchable electronic polymers. We demonstrate an intrinsically stretchable polymer transistor array with an unprecedented device density of 347 transistors per square centimetre. The transistors have an average charge-carrier mobility comparable to that of amorphous silicon, varying only slightly (within one order of magnitude) when subjected to 100 per cent strain for 1,000 cycles, without current-voltage hysteresis. Our transistor arrays thus constitute intrinsically stretchable skin electronics, and include an active matrix for sensory arrays, as well as analogue and digital circuit elements. Our process offers a general platform for incorporating other intrinsically stretchable polymer materials, enabling the fabrication of next generation stretchable skin electronic devices. PMID- 29466335 TI - Global elevational diversity and diversification of birds. AB - Mountain ranges harbour exceptionally high biodiversity, which is now under threat from rapid environmental change. However, despite decades of effort, the limited availability of data and analytical tools has prevented a robust and truly global characterization of elevational biodiversity gradients and their evolutionary origins. This has hampered a general understanding of the processes involved in the assembly and maintenance of montane communities. Here we show that a worldwide mid-elevation peak in bird richness is driven by wide-ranging species and disappears when we use a subsampling procedure that ensures even species representation in space and facilitates evolutionary interpretation. Instead, richness corrected for range size declines linearly with increasing elevation. We find that the more depauperate assemblages at higher elevations are characterized by higher rates of diversification across all mountain regions, rejecting the idea that lower recent diversification rates are the general cause of less diverse biota. Across all elevations, assemblages on mountains with high rates of past temperature change exhibit more rapid diversification, highlighting the importance of climatic fluctuations in driving the evolutionary dynamics of mountain biodiversity. While different geomorphological and climatic attributes of mountain regions have been pivotal in determining the remarkable richness gradients observed today, our results underscore the role of ongoing and often very recent diversification processes in maintaining the unique and highly adapted biodiversity of higher elevations. PMID- 29466336 TI - Population snapshots predict early haematopoietic and erythroid hierarchies. AB - The formation of red blood cells begins with the differentiation of multipotent haematopoietic progenitors. Reconstructing the steps of this differentiation represents a general challenge in stem-cell biology. Here we used single-cell transcriptomics, fate assays and a theory that allows the prediction of cell fates from population snapshots to demonstrate that mouse haematopoietic progenitors differentiate through a continuous, hierarchical structure into seven blood lineages. We uncovered coupling between the erythroid and the basophil or mast cell fates, a global haematopoietic response to erythroid stress and novel growth factor receptors that regulate erythropoiesis. We defined a flow cytometry sorting strategy to purify early stages of erythroid differentiation, completely isolating classically defined burst-forming and colony-forming progenitors. We also found that the cell cycle is progressively remodelled during erythroid development and during a sharp transcriptional switch that ends the colony forming progenitor stage and activates terminal differentiation. Our work showcases the utility of linking transcriptomic data to predictive fate models, and provides insights into lineage development in vivo.

PMID- 29466339 TI - Intragenic origins due to short G1 phases underlie oncogene-induced DNA replication stress. AB - Oncogene-induced DNA replication stress contributes critically to the genomic instability that is present in cancer. However, elucidating how oncogenes deregulate DNA replication has been impeded by difficulty in mapping replication initiation sites on the human genome. Here, using a sensitive assay to monitor nascent DNA synthesis in early S phase, we identified thousands of replication initiation sites in cells before and after induction of the oncogenes CCNE1 and MYC. Remarkably, both oncogenes induced firing of a novel set of DNA replication origins that mapped within highly transcribed genes. These ectopic origins were normally suppressed by transcription during G1, but precocious entry into S phase, before all genic regions had been transcribed, allowed firing of origins within genes in cells with activated oncogenes. Forks from oncogene-induced origins were prone to collapse, as a result of conflicts between replication and transcription, and were associated with DNA double-stranded break formation and chromosomal rearrangement breakpoints both in our experimental system and in a large cohort of human cancers. Thus, firing of intragenic origins caused by premature S phase entry represents a mechanism of oncogene-induced DNA replication stress that is relevant for genomic instability in human cancer. PMID- 29466338 TI - Extreme disorder in an ultrahigh-affinity protein complex. AB - Molecular communication in biology is mediated by protein interactions. According to the current paradigm, the specificity and affinity required for these interactions are encoded in the precise complementarity of binding interfaces. Even proteins that are disordered under physiological conditions or that contain large unstructured regions commonly interact with well-structured binding sites on other biomolecules. Here we demonstrate the existence of an unexpected interaction mechanism: the two intrinsically disordered human proteins histone H1 and its nuclear chaperone prothymosin-alpha associate in a complex with picomolar affinity, but fully retain their structural disorder, long-range flexibility and highly dynamic character. On the basis of closely integrated experiments and molecular simulations, we show that the interaction can be explained by the large opposite net charge of the two proteins, without requiring defined binding sites or interactions between specific individual residues. Proteome-wide sequence analysis suggests that this interaction mechanism may be abundant in eukaryotes.

PARTICIPANTS & SETTING: 18 HCT survivors who were aged 18-29 years at the time of HCT for a primary hematologic malignancy and were 8-60 months post-HCT participated in the study. The study took place in the hematology outpatient setting at City of Hope National Medical Center.?. METHODOLOGIC APPROACH: The authors conducted in depth semistructured interviews and analyzed interview transcripts using grounded theory methodology.?. FINDINGS: Health-related setbacks following HCT disrupted not only participants' journey toward self-care, but also their overarching developmental trajectory toward adulthood. Physically, participants struggled with lack of personal space around caregivers, but felt unready to live on their own. Socially, they relied on multiple caregivers to avoid relying too much on any one person. Financially, participants worried about prolonged dependence and increased needs in the future.?. IMPLICATIONS FOR NURSING: Nurses can support the transition to self-care among emerging adults after HCT by recognizing the broader developmental impact of their cancer experience. PMID- 29466342 TI - Early Identification of Intracranial Hemorrhage Using a Predictive Nomogram AB - OBJECTIVES: To identify predictive signs and symptoms occurring in hospitalized adults with hematologic malignancies with intracranial hemorrhage (IH).?. SAMPLE & SETTING: In a National Cancer Institute (NCI)-designated comprehensive cancer center, a retrospective matched case-control design included adult inpatients with hematologic malignancies with (n = 39) and without (n = 39) IH.?. METHODS & VARIABLES: Conditional logistic regression, t test, and Fisher's exact tests were used to assess increased risks for IH and the development of a prognostic nomogram with signs, symptoms, and laboratory values relevant to IH. ?. RESULTS: Composite outcomes for signs, symptoms, and laboratory values were included in a prognostic nomogram that had good discriminative ability to predict IH, with a bootstrap corrected concordance index of 0.766 (95% confidence interval [0.657, 0.866]) and good calibration. Prognostic nomogram predicted patients with prolonged activated partial thromboplastin time (APTT) (greater than 30.6), headache, and systolic blood pressure (SBP) of 140 or greater were more likely to have IH. ?. IMPLICATIONS FOR NURSING: Nurses should recognize that patients with the combination of prolonged APTT, SBP of 140 or greater, and headache are more likely to have IH.

By bypassing the effects of disparities, the POP-C intervention may help to decrease suffering among African American patients with cancer pain; consequently, it contributes to improving quality of life and addressing social and other determinants of health among members of this population. ?. PMID- 29466344 TI - Censorship, Then and Now AB - As I was thinking about a topic for this editorial, news and social media outlets exploded with the announcement that employees at the Centers for Disease Control and Prevention (CDC) had been instructed to not use any of seven words or phrases in budget documents (diversity, transgender, fetus, unborn child, vulnerable, evidence-?based, and science-based). To say that this hit a nerve is an understatement. My Twitter feed and email inbox filled with messages of outrage and concern, and I must admit I was swept up in the outpouring of anger. A call went out for editors of nursing journals to write editorials about this, and I was ready to do just that. ?. PMID- 29466337 TI - The Beaker phenomenon and the genomic transformation of northwest Europe. AB - From around 2750 to 2500 bc, Bell Beaker pottery became widespread across western and central Europe, before it disappeared between 2200 and 1800 bc. The forces that propelled its expansion are a matter of long-standing debate, and there is support for both cultural diffusion and migration having a role in this process. Here we present genome-wide data from 400 Neolithic, Copper Age and Bronze Age Europeans, including 226 individuals associated with Beaker-complex artefacts. We detected limited genetic affinity between Beaker-complex-associated individuals from Iberia and central Europe, and thus exclude migration as an important mechanism of spread between these two regions. However, migration had a key role in the further dissemination of the Beaker complex. We document this phenomenon most clearly in Britain, where the spread of the Beaker complex introduced high levels of steppe-related ancestry and was associated with the replacement of approximately 90% of Britain's gene pool within a few hundred years, continuing the east-to-west expansion that had brought steppe-related ancestry into central and northern Europe over the previous centuries. PMID- 29466345 TI - Symptom Dimensions as Outcomes in Interventions for Patients With Cancer: A Systematic Review AB - PROBLEM IDENTIFICATION: Symptom experience in patients with cancer consists of several dimensions, often measured descriptively within various populations but seldom used as intervention outcomes. This review aims at describing symptom dimensions as outcomes of interventions designed to alleviate symptoms in patients with cancer and to describe these interventions' effects on at least two symptom dimensions. ?. LITERATURE SEARCH: The PRISMA statement for reporting systematic reviews was used. Searches were undertaken in various indexing sites.?. DATA EVALUATION: Extracted data included design, participants, intervention and control group treatment, targeted symptom dimension, and summary of results.?. SYNTHESIS: 2,041 articles were identified and 15 were included. The symptom dimensions were intensity, distress, prevalence, frequency, consequences, and quality. Eleven interventions had significant effect on symptom dimensions, mostly on intensity and distress.?. IMPLICATIONS FOR PRACTICE: Oncology nurses need clinical skills to be able to understand patients' experiences through their narratives. Various interventions are targeted at symptoms, and these need to be implemented to provide evidence-based symptom management. PMID- 29466346 TI - Oncology Nurses' Knowledge, Confidence, and Practice in Addressing Caregiver Strain and Burden AB - OBJECTIVES: To describe nurses' practices, confidence, and knowledge of evidence based interventions for cancer caregiver strain and burden and to identify factors that contribute to these aspects. ?. SAMPLE & SETTING: 2,055 Oncology Nursing Society members completed an emailed survey.?. METHODS & VARIABLES: Pooled analysis of survey results. Variables included the baseline nursing assessment, intervention, confidence, knowledge, strategies used, and barriers encountered. ?. RESULTS: Nurses tend to overestimate the strength of evidence for interventions not shown to be effective and have moderate confidence in assessing and intervening with caregivers. Having been an informal caregiver and having received care from an informal caregiver were associated with higher reported practice and confidence. Major strategies used were referral to social workers and others. Barriers reported were financial, caregiver emotional responses, and distance. ?. IMPLICATIONS FOR NURSING: An opportunity exists to increase nurses' knowledge and confidence in assessment and intervention with caregivers. Greater use of technology may help nurses overcome some barriers to working with caregivers. Findings can be used to plan continuing education, develop clinical processes, and identify resources nurses need to address strain and burden among informal caregivers. PMID- 29466347 TI - Effects of Peer-Led Interventions for Patients With Cancer: A Meta-Analysis AB - PROBLEM IDENTIFICATION: To evaluate the effects of peer-led supportive interventions for patients with cancer.?. LITERATURE SEARCH: Six electronic databases (EMBASE, MEDLINE(r), Google Scholar, Cochrane Library, ProQuest Medical Library, and CINAHL(r)) were searched for articles published from 1997 to May 2017.?. DATA EVALUATION: A total of 159 studies were identified. Eighteen (16 randomized, controlled trials [RCTs] and 2 non-RCTs) were eligible for systematic review and 16 for meta-analysis. The Cochrane risk of bias tool and Comprehensive Meta-Analysis software were used for analysis.?. SYNTHESIS: The authors synthesized the results of the effect size of each trial according to cancer symptoms, coping, emotional health, quality of life, self-efficacy, sexuality, social support, and health-related behaviors. ?. IMPLICATIONS FOR RESEARCH: The findings from this study suggest that an additional tiered evaluation that has a theoretical underpinning and high-quality methodology is required to confirm the efficacy of peer-led supportive interventions within cancer care models. PMID- 29466348 TI - Perceived Needs, Preparedness, and Emotional Distress of Male Caregivers of Postsurgical Women With Gynecologic Cancer AB - OBJECTIVES: To describe the perceived needs, preparedness, and emotional distress of male caregivers of postsurgical patients with gynecologic cancer during the transition from hospital to home. ?. SAMPLE & SETTING: 50 male caregivers of patients with gynecologic cancer on an inpatient unit at University Hospitals Seidman Cancer Center in Cleveland, OH.?. METHODS & VARIABLES: Caregiver needs, perceived preparedness, and emotional distress were measured at admission and at one week postdischarge. Instruments included the Comprehensive Needs Assessment Tool for Cancer Caregivers, Preparedness for Caregiving Scale, and National Comprehensive Cancer Network Distress Thermometer. The analysis consisted of descriptive statistics, Spearman's correlations, and univariate linear regressions.?. RESULTS: At both time points, male caregivers' greatest needs were interaction with the healthcare staff and information. Perceived preparedness was not associated with emotional distress. Male caregivers who were young, were employed, were unmarried, and had a lower income had greater needs.?. IMPLICATIONS FOR NURSING: A relational nursing care approach that maintains effective communication with male caregivers is essential. Nurses should broaden the caregiver assessment beyond the practical care of the patient.

This study investigated the information requirements of young women to support their treatment decision making at diagnosis.?. PARTICIPANTS & SETTING: A purposeful sample of 20 women diagnosed with breast cancer aged 40 years or younger who had undergone surgery and had participated in a large cohort study in the United Kingdom.?. METHODOLOGIC APPROACH: Audio recordings of semistructured interviews were used to reveal information received at the time of surgical treatment.?. FINDINGS: Themes identified were types of breast cancer, surgical treatments, nonsurgical treatments, fertility, and surgery and after surgery. Participants felt that information required throughout treatment was influenced by individual life circumstances, such as children or plans for children, relationships, and career intentions. Participants felt information was lacking on the effects of treatment on body image, reconstructive surgery, and genetic predisposition to breast cancer.?. IMPLICATIONS FOR NURSING: Knowledge of the information requirements of young women diagnosed with breast cancer allows nursing staff to provide tailored support at times identified as most useful. PMID- 29466350 TI - Heart Rate Variability Markers as Correlates of Survival in Recipients of Hematopoietic Cell Transplantation AB - OBJECTIVES: To assess pre-/post-transplantation changes in autonomic tone, as measured by heart rate variability (HRV), among patients undergoing hematopoietic cell transplantation (HCT) and to look at those changes as they relate to post transplantation survival rates. ?. SAMPLE & SETTING: Data were derived from a sample of 27 English-speaking patients undergoing allogeneic or autologous HCT at Stanford University. ?. METHODS & VARIABLES: A survival analysis using the Kaplan-Meier estimator was employed to explore whether increased HRV would enhance survival probabilities over time among patients undergoing HCT.?. RESULTS: An increased probability of survival was significantly related to increases in two HRV indexes. IMPLICATIONS FOR NURSING: HRV may be a useful predictor of mortality among patients undergoing HCT. Interventions deliverable by nurses could be used to enhance HRV for patients identified as being at risk for early mortality. PMID- 29466351 TI - Understanding Distress in the Hospital: A Qualitative Study Examining Adults With Cancer AB - PURPOSE: To measure the distress of hospitalized adults with cancer and identify strategies and behaviors to manage distress.?. PARTICIPANTS & SETTING: 185 adults with cancer hospitalized in a large tertiary hospital in the Midwest.?. METHODOLOGIC APPROACH: This study involved a one-time assessment using the National Comprehensive Cancer Network's (NCCN's) Distress Thermometer and two open-ended questions. Demographic data were reviewed, and responses to open-ended questions were analyzed by content analysis. A team approach was used to develop and validate themes. ?. FINDINGS: Strategies used by patients to manage distress were categorized as taking charge and embracing help. Helpful strategies were related to quality of life and relationship with care teams. ?. IMPLICATIONS FOR NURSING: Understanding of distress in hospitalized adults with cancer is limited, which warrants the attention of healthcare professionals. Study results have implications to enhance patient care and to address nationally established psychosocial care objectives and NCCN distress screening standards.

SAMPLE & SETTING: 310 African American patients were recruited from an urban comprehensive cancer center. The study took place in the patients' homes.?. METHODS & VARIABLES: A two-group randomized design with repeated measures was used. Data were analyzed with linear mixed effects regression analysis and structural equation change score models. Variables were pain, pain related distress, functional status, perceived control over pain, and the following antecedents to control. RESULTS: Functional status was improved in POP C participants relative to control group participants (p < 0.05). Distress also was differentially decreased (p < 0.05). Pain intensity ratings decreased significantly in all patients (p < 0.05). The largest intervention effects were observed in the living with pain component. ?. IMPLICATIONS FOR NURSING: Perceived control over pain was strongly related to functional status and is amenable to interventions using the POP-C intervention components described in this article.

AB - Microbial life can leave various traces (or biosignatures) in rocks, including biotic alteration textures, biominerals, enrichments of certain elements, organic molecules, or remnants of DNA. In basalt glass from the ocean floor, microbial alteration textures as well as chemical and isotopic biosignatures have been used to trace microbial activity. However, little is known about the relationship between the physical and chemical nature of the habitat and the prevalent types of biosignatures. Here, we report and compare strongly variable biosignatures from two different oceanic study sites. We analyzed rock samples for their textural biosignatures and associated organic molecules. The biosignatures from the 8 Ma North Pond Region, which represents young, well-oxygenated, and hydrologically active crust, are characterized by little textural diversity. The organic matter associated with those textures shows evidence for the occurrence of remnants of complex biomolecules like proteins. Comparably the biosignatures from the older Louisville Seamount Trail (~70 Ma) are more texturally diverse, but associated with organic molecules that are more degraded. The Louisville Seamount has less fresh glass left and decreased permeability, which metabolic pathways may dominate that only leave molecular biosignatures without textural evidence of glass alteration. We propose that diverse biosignatures in oceanic crust may form during different stages of crustal evolution. PMID- 29466354 TI - Identification of long-term trends and seasonality in high-frequency water quality data from the Yangtze River basin, China. AB - Comprehensive understanding of the long-term trends and seasonality of water quality is important for controlling water pollution. This study focuses on spatio-temporal distributions, long-term trends, and seasonality of water quality in the Yangtze River basin using a combination of the seasonal Mann-Kendall test and time-series decomposition. The used weekly water quality data were from 17 environmental stations for the period January 2004 to December 2015. Results show gradual improvement in water quality during this period in the Yangtze River basin and greater improvement in the Uppermost Yangtze River basin. The larger cities, with high GDP and population density, experienced relatively higher pollution levels due to discharge of industrial and household wastewater. There are higher pollution levels in Xiang and Gan River basins, as indicated by higher NH4-N and CODMn concentrations measured at the stations within these basins. Significant trends in water quality were identified for the 2004-2015 period. Operations of the three Gorges Reservoir (TGR) enhanced pH fluctuations and possibly attenuated CODMn, and NH4-N transportation. Finally, seasonal cycles of varying strength were detected for time-series of pollutants in river discharge. Seasonal patterns in pH indicate that maxima appear in winter, and minima in summer, with the opposite true for CODMn. Accurate understanding of long-term trends and seasonality are necessary goals of water quality monitoring system efforts and the analysis methods described here provide essential information for effectively controlling water pollution. PMID- 29466355 TI - Epigenome comparisons reveal linkage between gene expression and postnatal remodeling of chromatin domain topology. AB - Substantial evidence has accumulated linking epigenome change to alterations in stem cell function during postnatal development and aging. Yet much remains to be learned about causal relationships, and large gaps remain in our understanding of epigenome-transcriptome interactions. Here we investigate structural features of large histone H3K27me3-enriched regions in human stem cell-like monocytes and their dendritic cell derivatives, where the H3K27me3 modification is considered to demarcate Polycomb (PcG) domains. Both differentiation- and postnatal development-related change are explored, initially by confirming expected reciprocal relationships between transcript abundance and span of PcG domains overlapping transcribed regions. PcG-associated postnatal transcriptome change specific to the stem cell-like monocytes is found to be incompletely explained by conventional measures of PcG region structure. To address this, we introduce algorithms that quantify local nucleosome-scale conservation of PcG-region topology. It is shown that topology-based comparisons can reveal broad statistical linkage between postnatal gene down-regulation and epigenome remodeling; further, such comparisons provide access to a previously unexplored dimension of epigenome architecture. PMID- 29466357 TI - Bioerosion by pit-forming, temperate-reef sea urchins: History, rates and broader implications. AB - Sea urchins are dominant members of rocky temperate reefs around the world. They often occur in cavities within the rock, and fit so tightly, it is natural to assume they sculpted these "pits." However, there are no experimental data demonstrating they bore pits. If they do, what are the rates and consequences of bioerosion to nearshore systems? We sampled purple sea urchins, Strongylocentrotus purpuratus, from sites with four rock types, three sedimentary (two sandstones and one mudstone) and one metamorphic (granite). A year-long experiment showed urchins excavated depressions on sedimentary rocks in just months. The rate of pit formation varied with rock type and ranged from <5 yr for medium-grain sandstone to >100 yr for granite. In the field, there were differences in pit size and shapes of the urchins (height:diameter ratio). The pits were shallow and urchins flatter at the granite site, and the pits were deeper and urchins taller at the sedimentary sites. Although overall pit sizes were larger on mudstone than on sandstone, urchin size accounted for this difference. A second, short-term experiment, showed the primary mechanism for bioerosion was ingestion of the substratum. This experiment eliminated potential confounding factors of the year-long experiment and yielded higher bioerosion rates. Given the high densities of urchins, large amounts of rock can be converted to sediment over short time periods. Urchins on sandstone can excavate as much as 11.4 kg m-2 yr-1. On a broader geographic scale, sediment production can exceed 100 t ha-1 yr-1, and across their range, their combined bioerosion is comparable to the sediment load of many rivers. The phase shift between urchin barrens and kelp bed habitats in the North Pacific is controlled by the trophic cascade of sea otters. By limiting urchin populations, these apex predators also may indirectly control a substantial component of coastal rates of bioerosion. PMID- 29466356 TI - Emergence of resistance mutations in simian immunodeficiency virus (SIV)-infected rhesus macaques receiving non-suppressive antiretroviral therapy (ART). AB - Two SIVmac251-infected rhesus macaques received tenofovir/emtricitabine with raltegravir intensification. Viral rebound occurred during treatment and sequencing of reverse transcriptase and integrase genes identified multiple resistance mutations. Similar to HIV infection, antiretroviral-resistance mutations may occur in SIV-infected nonhuman primates receiving nonsuppressive ART. As ART administration to nonhuman primates is currently dramatically expanding, fueled by both cure research and the study of HIV-related comorbidities, viral resistance should be factored in the study design and data interpretation. PMID- 29466358 TI - Cycle-specific female preferences for visual and non-visual cues in the horse (Equus caballus). AB - Although female preferences are well studied in many mammals, the possible effects of the oestrous cycle are not yet sufficiently understood. Here we investigate female preferences for visual and non-visual male traits relative to the periodically cycling of sexual proceptivity (oestrus) and inactivity (dioestrus), respectively, in the polygynous horse (Equus caballus). We individually exposed mares to stallions in four experimental situations: (i) mares in oestrus and visual contact to stallions allowed, (ii) mares in oestrus, with blinds (wooden partitions preventing visual contact but allowing for acoustic and olfactory communication), (iii) mares in dioestrus, no blinds, and (iv) mares in dioestrus, with blinds. Contact times of the mares with each stallion, defined as the cumulative amount of time a mare was in the vicinity of an individual stallion and actively searching contact, were used to rank stallions according to each mare's preferences. We found that preferences based on visual traits differed significantly from preferences based on non-visual traits in dioestrous mares. The mares then showed a preference for older and larger males, but only if visual cues were available. In contrast, oestrous mares showed consistent preferences with or without blinds, i.e. their preferences were mainly based on non-visual traits and could not be predicted by male age or size. Stallions who were generally preferred displayed a high libido that may have positively influenced female interest or may have been a consequence of it. We conclude that the oestrous cycle has a significant influence on female preferences for visual and non-visual male traits in the horse. PMID- 29466359 TI - CDK activity provides temporal and quantitative cues for organizing genome duplication. AB - In eukaryotes, the spatial and temporal organization of genome duplication gives rise to distinctive profiles of replication origin usage along the chromosomes. While it has become increasingly clear that these programs are important for cellular physiology, the mechanisms by which they are determined and modulated remain elusive. Replication initiation requires the function of cyclin-dependent kinases (CDKs), which associate with various cyclin partners to drive cell proliferation. Surprisingly, although we possess detailed knowledge of the CDK regulators and targets that are crucial for origin activation, little is known about whether CDKs play a critical role in establishing the genome-wide pattern of origin selection. We have addressed this question in the fission yeast, taking advantage of a simplified cell cycle network in which cell proliferation is driven by a single cyclin-CDK module. This system allows us to precisely control CDK activity in vivo using chemical genetics. First, in contrast to previous reports, our results clearly show that distinct cyclin-CDK pairs are not essential for regulating specific subsets of origins and for establishing a normal replication program. Importantly, we then demonstrate that the timing at which CDK activity reaches the S phase threshold is critical for the organization of replication in distinct efficiency domains, while the level of CDK activity at the onset of S phase is a dose-dependent modulator of overall origin efficiencies. Our study therefore implicates these different aspects of CDK regulation as versatile mechanisms for shaping the architecture of DNA replication across the genome.

AB - INTRODUCTION: The discovery of new treatments that prevent or treat preeclampsia would be a major advance. Antiangiogenic factors soluble fms-like tyrosine kinase 1 (sFlt-1) and soluble endoglin (sENG) are secreted in excess from the placenta, causing hypertension, endothelial dysfunction, and multiorgan injury. We recently identified metformin and esomeprazole as potential treatments for preeclampsia. Both reduce placental and endothelial secretion of sFlt-1 and soluble endoglin, and reduce endothelial dysfunction. OBJECTIVES: We set out to assess whether combining metformin and esomeprazole would additively reduce sFlt-1 and soluble endoglin secretion and reduce endothelial dysfunction (verses drug alone). Metformin and esomeprazole were added to primary placental cells and tissues, and endothelial cells and their effects on sFlt-1 and soluble endoglin secretion were assessed in vitro. Tumor necrosis factor-alpha (TNF-alpha) was added to endothelial cells to induce dysfunction in vitro. We examined the ability of metformin + esomeprazole to rescue TNF-alpha induced vascular cell adhesion molecule-1 (VCAM-1) and Endothelin-1 (ET-1) expression, leukocyte adhesion (markers of endothelial dysfunction). RESULTS: Combining metformin and esomeprazole was additive at reducing sFlt-1 secretion and expression of sFlt-1 e15a mRNA isoform in primary cytotrophoblast, placental explants and endothelial cells. In contrast, no additive reduction in sENG was observed with combined metformin and esomeprazole. The low-dose combination of metformin + esomeprazole additively reduced TNF-alpha-induced VCAM-1 mRNA, but not VCAM-1 protein expression. There was no additive reduction when combining metformin and esomeprazole on TNF-alpha induced PBMC adhesion to endothelial cells. However, combining metformin and esomeprazole additively reduced ET-1 mRNA expression. CONCLUSIONS: In conclusion combining metformin and esomeprazole additively reduced secretion of sFlt-1, and markers of endothelial dysfunction. The combination of metformin and esomeprazole may provide a more effective treatment or prevention for preeclampsia compared to either as single agents. PMID- 29466361 TI - Is there relationship between epicardial fat and cardiovascular parameters in incident kidney transplant patients? A post-hoc analysis. AB - BACKGROUND: Epicardial fat (EF) has been related to increased cardiovascular risk in chronic kidney disease patients. Kidney transplantation is associated with weight gain, especially within the first 12 months. Recently an association between EF and left ventricular mass (LVM) has been suggested in kidney transplant (KTX) recipients. OBJECTIVE: Evaluate the EF in KTX recipients and its association with cardiovascular parameters in a 12-month follow-up study. METHODS: EF volume was determined using thoracic computed tomography. The EF progressor group (EF gain) was defined by any increment in EF after 12 months. LVM and LVM index were calculated by echocardiography. RESULTS: Ninety-eight incident KTX patients [57% men, 41.2 +/- 10.1 years, mean dialysis time prior to transplant of 24 (11-60) months] were analyzed. At baseline and after 12 months, EF was 318.6 (275.2-392.6) ml and 329.5 (271.7-384.8) ml, respectively (p = 0.03). When compared to patients who EF decreased (n = 33), those with EF gain (n = 65) had a greater increase of body mass index, abdominal circumference and blood glucose. These patients also had a lower reduction of LVM index. However in the multivariate analysis, there was no difference in LVM index change between groups (interaction p = 0.565), even after adjustment for hypertension, glucose and coronary calcium score (interaction p = 0.538). CONCLUSION: The impact of EF gain on ventricular mass after KTX could not be definitely confirmed. Further prospective studies in a large sample of KTX patients should be considered to address a possible causal relationship between EF gain and cardiac hypertrophy in this population.

AB - Androdioecy (co-existence of hermaphrodites and dwarf males) is a fascinating yet poorly understood phenomenon. The pedunculated barnacle Scalpellum scalpellum is an emerging model species for the system. In S. scalpellum, dwarf males and hermaphrodites are very different in adult morphology (e.g., in feeding structures and reproductive organs), but they share the same larval development with nauplii followed by cypris larvae. Recently, it was found that S. scalpellum cypris larvae display both genetic and environmental sex determination, but no detailed morphological study has yet investigated how the settled cypris larvae differ subsequent to settlement. This study investigates the morphological aspects of the onset of sex determination in the cyprids of S. scalpellum by examining their metamorphosis into either dwarf males or hermaphrodites under laboratory conditions. This study emphasizes morphological differences, such as size and shape of primordial shell plates, development of a flexible peduncle and of thoracopods. It was shown that the cypris larvae start to differ already one day after settlement on either a hydroid (leading to hermaphrodites) or an adult hermaphrodite (leading to dwarf males). Dwarf males gradually developed an ovoid body shape and two pairs of circular scutal and tergal primordia. Such cyprids developed neither a carina nor any peduncle or cirri for feeding. The study concludes that the dwarf males of S. scalpellum are not just hermaphrodites arrested early in development. This entails that dwarf males constitute their own separate developmental pathways and points to S. scalpellum dwarf males being more specialized than previously stated. Finally, the study compares differences in dwarf male morphology between S. scalpellum with two other androdioecious species with less specialized dwarf males and use this to discuss evolutionary implications for the adaptive evolution of dwarf males across the Cirripedia. PMID- 29466362 TI - The influence of speed and size on avian terrestrial locomotor biomechanics: Predicting locomotion in extinct theropod dinosaurs. AB - How extinct, non-avian theropod dinosaurs moved is a subject of considerable interest and controversy. A better understanding of non-avian theropod locomotion can be achieved by better understanding terrestrial locomotor biomechanics in their modern descendants, birds. Despite much research on the subject, avian terrestrial locomotion remains little explored in regards to how kinematic and kinetic factors vary together with speed and body size. Here, terrestrial locomotion was investigated in twelve species of ground-dwelling bird, spanning a 1,780-fold range in body mass, across almost their entire speed range. Particular attention was devoted to the ground reaction force (GRF), the force that the feet exert upon the ground. Comparable data for the only other extant obligate, striding biped, humans, were also collected and studied. In birds, all kinematic and kinetic parameters examined changed continuously with increasing speed, while in humans all but one of those same parameters changed abruptly at the walk-run transition. This result supports previous studies that show birds to have a highly continuous locomotor repertoire compared to humans, where discrete 'walking' and 'running' gaits are not easily distinguished based on kinematic patterns alone. The influences of speed and body size on kinematic and kinetic factors in birds are developed into a set of predictive relationships that may be applied to extinct, non-avian theropods. The resulting predictive model is able to explain 79-93% of the observed variation in kinematics and 69-83% of the observed variation in GRFs, and also performs well in extrapolation tests. However, this study also found that the location of the whole-body centre of mass may exert an important influence on the nature of the GRF, and hence some caution is warranted, in lieu of further investigation. PMID- 29466364 TI - Abnormalities in gray matter volume in patients with borderline personality disorder and their relation to lifetime depression: A VBM study. AB - BACKGROUND: Structural imaging studies of borderline personality disorder (BPD) have found regions of reduced cortical volume, but these have varied considerably across studies. Reduced hippocampus and amygdala volume have also been a regular finding in studies using conventional volumetric measurement. How far comorbid major depression, which is common in BPD and can also affect in brain structure, influences the findings is not clear. METHODS: Seventy-six women with BPD and 76 matched controls were examined using whole-brain voxel-based morphometry (VBM). The hippocampus and amygdala were also measured, using both conventional volume measurement and VBM within a mask restricted to these two subcortical structures. Lifetime history of major depression was assessed using structured psychiatric interview. RESULTS: At a threshold of p = 0.05 corrected, the BPD patients showed clusters of volume reduction in the dorsolateral prefrontal cortex bilaterally and in the pregenual/subgenual medial frontal cortex. There was no evidence of volume reductions in the hippocampus or amygdala, either on conventional volumetry or using VBM masked to these regions. Instead there was evidence of right-sided enlargement of these structures. No significant structural differences were found between patients with and without lifetime major depression. CONCLUSIONS: According to this study, BPD is characterized by a restricted pattern of cortical volume reduction involving the dorsolateral frontal cortex and the medial frontal cortex, both areas of potential relevance for the clinical features of the disorder. Previous findings concerning reduced hippocampus and amygdala volume in the disorder are not supported. Brain structural findings in BPD do not appear to be explainable on the basis of history of associated lifetime major depression. PMID- 29466365 TI - Cross-reactive microbial peptides can modulate HIV-specific CD8+ T cell responses. AB - Heterologous immunity is an important aspect of the adaptive immune response. We hypothesized that this process could modulate the HIV-1-specific CD8+ T cell response, which has been shown to play an important role in HIV-1 immunity and control. We found that stimulation of peripheral blood mononuclear cells (PBMCs) from HIV-1-positive subjects with microbial peptides that were cross-reactive with immunodominant HIV-1 epitopes resulted in dramatic expansion of HIV-1 specific CD8+ T cells. Interestingly, the TCR repertoire of HIV-1-specific CD8+ T cells generated by ex vivo stimulation of PBMCs using HIV-1 peptide was different from that of cells stimulated with cross-reactive microbial peptides in some HIV 1-positive subjects. Despite these differences, CD8+ T cells stimulated with either HIV-1 or cross-reactive peptides effectively suppressed HIV-1 replication in autologous CD4+ T cells. These data suggest that exposure to cross-reactive microbial antigens can modulate HIV-1-specific immunity. PMID- 29466366 TI - Meta-analysis of the clinical behavior of posterior direct resin restorations: Low polymerization shrinkage resin in comparison to methacrylate composite resin. AB - Polymerization shrinkage of resin composite can compromise the longevity of restorations. To minimize this problem, the monomeric composition of composites have been modified. The objective of this study was to conduct a meta-analysis to assess the clinical behavior of restorations performed with low polymerization shrinkage resin composite in comparison with traditional methacrylates-based resin composite. This systematic review was registered at Prospero data system (CRD42015023940). Studies were searched in the electronic databases PubMed, Web of Science, Scopus, Lilacs and EMBASE according to a predefined search strategy. The inclusion criteria were as follow: (1) randomized controlled clinical trials with at least six months of follow-up; (2) studies investigating composites with monomers designed to reduce polymerization shrinkage; (3) studies conducted with class I or II restorations in the permanent dentition; and (4) studies that assessed at least one of the following criteria: marginal integrity/adaptation, marginal discoloration, recurent caries, retention of composite restorations, and postoperative sensitivity. Two independent reviewers analyzed the articles to determine inclusion and risk of bias. The search conducted in the databases resulted in a total of 14,217 studies. After reviewing the references and citations, 21 articles remained. The longest clinical follow-up time was 60 months. The meta-analysis of the data in the included studies demonstrated that only one variable (marginal adaptation after 12 months) showed statistically significant outcomes, in which methacrylates-based composites presented significantly better results than resin composites containing modified monomers. The good level of the scientific evidence as well as the overall low risk of bias of the included studies indicate that composites with silorane, ormocer or bulk fill type modified monomers have a clinical performance similar to conventional resin composites. PMID- 29466367 TI - Differentiated embryo chondrocyte plays a crucial role in DNA damage response via transcriptional regulation under hypoxic conditions. AB - Tumor hypoxia contributes to a biologically aggressive phenotype and therapeutic resistance. Recent studies have revealed that hypoxia reduces expression of several DNA damage recognition and repair (DRR) genes via both hypoxia-inducible factor (HIF)-independent and -dependent pathways, and this induced genomic instability in cancer cells. We show here that one of the HIF-target genes differentiated embryo chondrocyte (DEC)-plays a role in DNA damage response via transcriptional repression. Comprehensive gene expression and database analyses have revealed systemic repression of DNA-DRR genes in cancer and non-cancer cells under hypoxic conditions. Hypoxic repression in typical cases was confirmed by quantitative RT-PCR and promoter reporter experiments, and knockdown experiments indicated the critical role of DEC2 in such repression. Assessment of histone H2AX phosphorylation revealed that recognition and repair of DNA double-strand breaks (DSBs) induced by bleomycin or gamma-ray irradiation were attenuated; moreover, Cleaved Caspase-3 levels were decreased with pre-conditioning under hypoxia: opposing phenomena were ascertained by knockdown of DEC2. Finally, pre conditioning under hypoxia decreased the sensitivity of cancer cells to DSBs, and knockdown of DEC2 increased gamma-ray sensitivity. These data imply that a critical reduction of DNA-DRR occurs via DEC-dependent transcriptional repression and suggest that DEC is a potential molecular target for anti-cancer strategies. PMID- 29466368 TI - Untargeted metabolomics reveals distinct metabolic reprogramming in endothelial cells co-cultured with CSC and non-CSC prostate cancer cell subpopulations. AB - Tumour angiogenesis is an important hallmark of cancer and the study of its metabolic adaptations, downstream to any cellular change, can reveal attractive targets for inhibiting cancer growth. In the tumour microenvironment, endothelial cells (ECs) interact with heterogeneous tumour cell types that drive angiogenesis and metastasis. In this study we aim to characterize the metabolic alterations in ECs influenced by the presence of tumour cells with extreme metastatic abilities. Human umbilical vein endothelial cells (HUVECs) were subjected to different microenvironmental conditions, such as the presence of highly metastatic PC-3M and highly invasive PC-3S prostate cancer cell lines, in addition to the angiogenic activator vascular endothelial growth factor (VEGF), under normoxia. Untargeted high resolution liquid chromatography-mass spectrometry (LC-MS) based metabolomics revealed significant metabolite differences among the various conditions and a total of 25 significantly altered metabolites were identified including acetyl L-carnitine, NAD+, hypoxanthine, guanine and oleamide, with profile changes unique to each of the experimental conditions. Biochemical pathway analysis revealed the importance of fatty acid oxidation and nucleotide salvage pathways. These results provide a global metabolic preview that could help in selectively targeting the ECs aiding in either cancer cell invasion or metastasis in the heterogeneous tumour microenvironment. PMID- 29466370 TI - Joint optimization of green vehicle scheduling and routing problem with time varying speeds. AB - Based on an analysis of the congestion effect and changes in the speed of vehicle flow during morning and evening peaks in a large- or medium-sized city, the piecewise function is used to capture the rules of the time-varying speed of vehicles, which are very important in modelling their fuel consumption and CO2 emission. A joint optimization model of the green vehicle scheduling and routing problem with time-varying speeds is presented in this study. Extra wages during nonworking periods and soft time-window constraints are considered. A heuristic algorithm based on the adaptive large neighborhood search algorithm is also presented. Finally, a numerical simulation example is provided to illustrate the optimization model and its algorithm. Results show that, (1) the shortest route is not necessarily the route that consumes the least energy, (2) the departure time influences the vehicle fuel consumption and CO2 emissions and the optimal departure time saves on fuel consumption and reduces CO2 emissions by up to 5.4%, and (3) extra driver wages have significant effects on routing and departure time slot decisions. PMID- 29466369 TI - Induction of epigenetic variation in Arabidopsis by over-expression of DNA METHYLTRANSFERASE1 (MET1). AB - Epigenetic marks such as DNA methylation and histone modification can vary among plant accessions creating epi-alleles with different levels of expression competence. Mutations in epigenetic pathway functions are powerful tools to induce epigenetic variation. As an alternative approach, we investigated the potential of over-expressing an epigenetic function, using DNA METHYLTRANSFERASE1 (MET1) for proof-of-concept. In Arabidopsis thaliana, MET1 controls maintenance of cytosine methylation at symmetrical CG positions. At some loci, which contain dense DNA methylation in CG- and non-CG context, loss of MET1 causes joint loss of all cytosines methylation marks. We find that over-expression of both catalytically active and inactive versions of MET1 stochastically generates new epi-alleles at loci encoding transposable elements, non-coding RNAs and proteins, which results for most loci in an increase in expression. Individual transformants share some common phenotypes and genes with altered gene expression. Altered expression states can be transmitted to the next generation, which does not require the continuous presence of the MET1 transgene. Long-term stability and epigenetic features differ for individual loci. Our data show that over-expression of MET1, and potentially of other genes encoding epigenetic factors, offers an alternative strategy to identify epigenetic target genes and to create novel epi-alleles. PMID- 29466371 TI - Ezh2 is not required for cardiac regeneration in neonatal mice. AB - The neonatal mouse heart has the remarkable capacity to regenerate lost myocardium within the first week of life. Neonatal cardiomyocytes re-express fetal genes that control cell proliferation after injury to promote regeneration. The loss of regenerative capacity of the heart one week after birth coincides with repression of a fetal transcriptional program coordinated by epigenetic regulators. The histone methyltransferase enhancer of zeste homolog 2 (Ezh2) is a repressor of fetal cardiac transcriptional programs and suppresses cardiomyocyte cell proliferation, suggesting a potential function in heart regeneration. However, it was recently demonstrated that Ezh2 is dispensable for heart regeneration in the neonatal heart. Here, we provide evidence supporting this finding and demonstrate that Ezh2 deficiency does not affect regeneration of the neonatal heart. We inactivated Ezh2 in differentiating embryonic cardiomyocytes, which led to depletion of histone H3 trimethylated at lysine 27 (H3K27me3). Ezh2 deficiency in cardiomyocytes did not affect clearance of the fibrotic scar in myocardial infarction (MI) and apical resection models of cardiac injury at post natal day 1 (P1). Similarly, cardiomyocyte-specific loss of Ezh2 did not affect fibrotic scar size after MI or apical resection at P7, suggesting that it does not extend the regenerative time window. Our results demonstrate that Ezh2 is not required for innate neonatal cardiac regeneration. PMID- 29466372 TI - Evaluating the use of stable isotope analysis to infer the feeding ecology of a growing US gray seal (Halichoerus grypus) population. AB - Gray seals (Halichoerus grypus) have been rapidly recolonizing the Northeast US coast, eliciting concern from the fishing industry. However, the ecological effect of this recovery is still unknown and as such, research is needed to better understand how the diet composition of gray seals in US waters will contribute to the ecological impact. While previous research on seal diets has focused on the analysis of hard prey remains, stable isotope analysis presents an alternative method that can be used to describe marine mammal diets when direct observation is impossible. To address this issue, we used stable isotope analysis of gray seal pup vibrissae and lanugo from Monomoy Island, Cape Cod, MA during the 2015/2016 winter breeding season to estimate adult female diet composition during pregnancy. Stable isotope mixing models (SIMM) suggested adult female gray seals were consuming greater amounts of cephalopod prey and less sand lance than previously indicated from analysis of hard prey remains. However, using SIMMs to estimate the diet composition of gray seals remains difficult due to the large number of isotopically similar prey species and uncertainty in tissue-specific, stable isotope trophic enrichment factors. Even so, by combining prey sources into ecologically informative groups and integrating prior information into SIMMs it is possible to obtain additional insights into the diet of this generalist predator. PMID- 29466373 TI - Observations on the symbiotic relationship between the caridean shrimp Odontonia sibogae (Bruce, 1972) and its ascidian host Herdmania momus (Savigny, 1816). AB - Symbiotic relationships between shrimps and other invertebrates are a very common phenomenon in tropical environments. Although the caridean shrimp-ascidian association has been known for many years, the nature of this relationship is still unclear. The current study investigated the association between the caridean shrimp Odontonia sibogae (Bruce, 1972) and solitary ascidians. A combination of field work conducted along the Red Sea coast of Israel and laboratory experiments, conducted during 2015-2016, revealed a clear preference of the shrimps for the ascidian species Herdmania momus (Savigny, 1816), with a low survival ability of the shrimp outside their host's body. The shrimps usually inhabit their host as pairs of male and female or pair of females, but never as pairs of males. Out of the 53 studied females, 51% were observed to bear between 156-1,146 embryos, throughout the course of the year. As these ascidian hosts are known to create large aggregates, we suggest that males may possibly wander among the ascidians occupied by females in order to increase their reproductive success. To date, this is the first study to record the shrimp Dactylonia ascidicola (Borradaile, 1898) inhabiting the ascidian H. momus; and the first study to investigate in depth the ascidian-shrimp association in the Red Sea. It thus provides a platform for future research into the physiological and behavioral adaptations required for such a unique association. PMID- 29466374 TI - Storage in high-barrier pouches increases the sulforaphane concentration in broccoli florets. AB - Sulforaphane is a phytochemical that is usually found in cruciferous vegetables and is known to have a depressive effect on gastric cancer. Preliminary investigations showed that the sulforaphane concentration in broccoli (Brassica oleracea var. italica) florets increased under anoxia. Therefore, in the present study, we examined the effect of different atmospheric conditions on the sulforaphane concentration in broccoli and also tested whether there are concurrent effects on the concentration of ethanol, which is an unfavorable byproduct of fermentation. The sulforaphane concentration in broccoli florets was significantly elevated by 1.9- to 2.8-fold after 2 d of storage under hypoxia at ca. 0% O2 and ca. 24% CO2 at 20 degrees C, whereas no such increase was observed following storage under normoxia at ca. 0% O2 without CO2 at 20 degrees C. Furthermore, after 2 d, the sulforaphane concentration under hypoxia was 1.6- to 2.3-fold higher than that under normoxia. These results suggest that storage under hypoxia with high CO2 levels can elevate the sulforaphane concentration in broccoli florets. However, the elevated sulforaphane concentration could not be maintained beyond 2 d. There was no significant difference in the concentration of ethanol between florets that were stored under hypoxia with/without CO2 or normoxia at 2 d. However, the ethanol concentrations inside the pouches significantly increased between 2 d and 7 d. These findings indicate that the quality of broccoli florets can be improved through storage under hypoxia with high CO2 levels at 20 degrees C for 2 d. PMID- 29466375 TI - Effects of resource-dependent cannibalism on population size distribution and individual life history in a case-bearing caddisfly. AB - Resource availability often determines the intensity of cannibalism, which has a considerable effect on population size distribution and individual life history. Larvae of the caddisfly Psilotreta kisoensis build portable cases from sedimentary sands and often display cannibalism. For this species, the availability of preferable case material is a critical factor that affects larval fitness, and material is locally variable depending on the underlying geology. In this study, we investigated how sand quality as a case material determines cannibalism frequency among larvae and, in turn, how the differential cannibalism frequency affects the body-size distribution and voltinism. Rearing experiments within a cohort revealed that a bimodal size distribution developed regardless of material quality. However, as the preferable material became abundant, the proportion of larger to smaller individuals increased. Consecutive experiments suggested that smaller larvae were more frequently cannibalized by larger ones and excluded from the population when preferable smooth material was abundant. This frequent cannibalism resulted in a bimodal size distribution with a significantly higher proportion of larger compared to smaller individuals. The size-dependent cannibalism was significantly suppressed when the larvae were raised in an environment with a scarcity of the preferable case material. This is probably because larvae cannot enjoy the benefit of rapid growth by cannibalism due to the difficulties in enlarging their case. At low cannibalism the growth of smaller individuals was stunted, and this was probably due to risk of cannibalism by larger individuals. This growth reduction in small individuals led to a bimodal size-distribution but with a lower proportion of larger to smaller individuals compared to at high cannibalism. A field study in two streams showed a similar size distribution of larvae as was found in the rearing experiment. The bimodal ratio has consequences for life history, since a size-bimodal population causes a cohort splitting: only larvae that were fully grown at 1 year had a univoltine life cycle, whereas larvae with a stunted growth continued their larval life for another year (semivoltine). This study suggests that availability of preferable case building material is an important factor that affects cannibalism, which in turn affects larval population size structure and cohort splitting. PMID- 29466376 TI - Endosymbiont-based immunity in Drosophila melanogaster against parasitic nematode infection. AB - Associations between endosymbiotic bacteria and their hosts represent a complex ecosystem within organisms ranging from humans to protozoa. Drosophila species are known to naturally harbor Wolbachia and Spiroplasma endosymbionts, which play a protective role against certain microbial infections. Here, we investigated whether the presence or absence of endosymbionts affects the immune response of Drosophila melanogaster larvae to infection by Steinernema carpocapsae nematodes carrying or lacking their mutualistic Gram-negative bacteria Xenorhabdus nematophila (symbiotic or axenic nematodes, respectively). We find that the presence of Wolbachia alone or together with Spiroplasma promotes the survival of larvae in response to infection with S. carpocapsae symbiotic nematodes, but not against axenic nematodes. We also find that Wolbachia numbers are reduced in Spiroplasma-free larvae infected with axenic compared to symbiotic nematodes, and they are also reduced in Spiroplasma-containing compared to Spiroplasma-free larvae infected with axenic nematodes. We further show that S. carpocapsae axenic nematode infection induces the Toll pathway in the absence of Wolbachia, and that symbiotic nematode infection leads to increased phenoloxidase activity in D. melanogaster larvae devoid of endosymbionts. Finally, infection with either type of nematode alters the metabolic status and the fat body lipid droplet size in D. melanogaster larvae containing only Wolbachia or both endosymbionts. Our results suggest an interaction between Wolbachia endosymbionts with the immune response of D. melanogaster against infection with the entomopathogenic nematodes S. carpocapsae. Results from this study indicate a complex interplay between insect hosts, endosymbiotic microbes and pathogenic organisms. PMID- 29466377 TI - Understanding the psychiatric effects of concussion on constructed identity in hockey players: Implications for health professionals. AB - OBJECTIVE: The following study was undertaken to investigate the effect of concussion and psychiatric illness on athletes and their caregivers. METHODS: Semi-structured interviews with 20 ice hockey stakeholders (17 men and 3 women) including minor and professional players, coaches, parents, and physicians were conducted over two years (2012-2014). These interviews were analyzed using grounded theory. RESULTS: From this analysis, a common biographical theme emerged whereby the subject's identity as a hockey player, constructed early in life over many years, was disrupted by concussion. Furthermore, some players underwent a biographical deconstruction when they experienced post-concussive mental illness, which was amplified by isolation, stigma from peers, and lack of a clear life trajectory. Many players obtained support from family and peers and were able to recover, as evidenced by the biographical reconstruction of their identity post hockey concussion. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: Understanding the process of biographical deconstruction and reconstruction has significant psychosocial treatment implications for both healthcare professionals and caregivers of this population. Specifically, the authors suggest that interpersonal psychotherapy (IPT) that focuses on role transitions may create opportunities to facilitate the process of biographical reconstruction and life transition. PMID- 29466378 TI - Crystal structure of a cold-active protease (Pro21717) from the psychrophilic bacterium, Pseudoalteromonas arctica PAMC 21717, at 1.4 A resolution: Structural adaptations to cold and functional analysis of a laundry detergent enzyme. AB - Enzymes isolated from organisms found in cold habitats generally exhibit higher catalytic activity at low temperatures than their mesophilic homologs and are therefore known as cold-active enzymes. Cold-active proteases are very useful in a variety of biotechnological applications, particularly as active ingredients in laundry and dishwashing detergents, where they provide strong protein-degrading activity in cold water. We identified a cold-active protease (Pro21717) from a psychrophilic bacterium, Pseudoalteromonas arctica PAMC 21717, and determined the crystal structure of its catalytic domain (CD) at a resolution of 1.4 A. The Pro21717-CD structure shows a conserved subtilisin-like fold with a typical catalytic triad (Asp185, His244, and Ser425) and contains four calcium ions and three disulfide bonds. Interestingly, we observed an unexpected electron density at the substrate-binding site from a co-purified peptide. Although the sequence of this peptide is unknown, analysis of the peptide-complexed structure nonetheless provides some indication of the substrate recognition and binding mode of Pro21717. Moreover, various parameters, including a wide substrate pocket size, an abundant active-site loop content, and a flexible structure provide potential explanations for the cold-adapted properties of Pro21717. In conclusion, this is first structural characterization of a cold-adapted subtilisin-like protease, and these findings provide a structural and functional basis for industrial applications of Pro21717 as a cold-active laundry or dishwashing detergent enzyme. PMID- 29466379 TI - Activation of retinal glial (Muller) cells by extracellular ATP induces pronounced increases in extracellular H+ flux. AB - Small alterations in extracellular acidity are potentially important modulators of neuronal signaling within the vertebrate retina. Here we report a novel extracellular acidification mechanism mediated by glial cells in the retina. Using self-referencing H+-selective microelectrodes to measure extracellular H+ fluxes, we show that activation of retinal Muller (glial) cells of the tiger salamander by micromolar concentrations of extracellular ATP induces a pronounced extracellular H+ flux independent of bicarbonate transport. ADP, UTP and the non hydrolyzable analog ATPgammas at micromolar concentrations were also potent stimulators of extracellular H+ fluxes, but adenosine was not. The extracellular H+ fluxes induced by ATP were mimicked by the P2Y1 agonist MRS 2365 and were significantly reduced by the P2 receptor blockers suramin and PPADS, suggesting activation of P2Y receptors. Bath-applied ATP induced an intracellular rise in calcium in Muller cells; both the calcium rise and the extracellular H+ fluxes were significantly attenuated when calcium re-loading into the endoplasmic reticulum was inhibited by thapsigargin and when the PLC-IP3 signaling pathway was disrupted with 2-APB and U73122. The anion transport inhibitor DIDS also markedly reduced the ATP-induced increase in H+ flux while SITS had no effect. ATP-induced H+ fluxes were also observed from Muller cells isolated from human, rat, monkey, skate and lamprey retinae, suggesting a highly evolutionarily conserved mechanism of potential general importance. Extracellular ATP also induced significant increases in extracellular H+ flux at the level of both the outer and inner plexiform layers in retinal slices of tiger salamander which was significantly reduced by suramin and PPADS. We suggest that the novel H+ flux mediated by ATP-activation of Muller cells and of other glia as well may be a key mechanism modulating neuronal signaling in the vertebrate retina and throughout the brain. PMID- 29466380 TI - Q fever in Egypt: Epidemiological survey of Coxiella burnetii specific antibodies in cattle, buffaloes, sheep, goats and camels. AB - Q fever is a zoonotic disease caused by the bacterium Coxiella burnetii. Clinical presentation in humans varies from asymptomatic to flu-like illness and severe sequelae may be seen. Ruminants are often sub-clinically infected or show reproductive disorders such as abortions. In Egypt, only limited data on the epidemiology of Q fever in animals are available. Using a stratified two stage random sampling approach, we evaluated the prevalence of Coxiella burnetii specific antibodies among ruminants and camels in 299 herds. A total of 2,699 blood samples was investigated using enzyme-linked-immunosorbent assay (ELISA). Coxiella burnetii specific antibodies were detected in 40.7% of camels (215/528), 19.3% of cattle (162/840), 11.2% of buffaloes (34/304), 8.9% of sheep (64/716) and 6.8% of goats (21/311), respectively. Odds of seropositivity were significantly higher for cattle (aOR: 3.17; 95% CI: 1.96-5.13) and camels (aOR: 9.75; 95% CI: 6.02-15.78). Significant differences in seropositivity were also found between domains (Western Desert, Eastern Desert and Nile Valley and Delta) and 25 governorates (p < 0.001), respectively. Animal rearing in the Eastern Desert domain was found to be a significant risk factor (aOR: 2.16; 95% CI: 1.62 2.88). Most seropositive animals were older than four years. No correlation between positive titers and husbandry practices or animal origin were found (p > 0.05). Only 8.7% of the interviewed people living on the farms consumed raw camel milk and none reported prior knowledge on Q fever. Findings from this nationwide study show that exposure to Coxiella burnetii is common in ruminants and camels. Disease awareness among physicians, veterinarians and animal owners has to be raised. Future epidemiological investigations have to elucidate the impact of Q fever on human health and on the economy of Egypt. PMID- 29466381 TI - Transmission of fungal partners to incipient Cecropia-tree ant colonies. AB - Ascomycete fungi in the nests of ants inhabiting plants (= myrmecophytes) are very often cultivated by the ants in small patches and used as food source. Where these fungi come from is not known yet. Two scenarios of fungus recruitment are possible: (1) random infection through spores or hyphal fragments from the environment, or (2) transmission from mother to daughter colonies by the foundress queen. It is also not known at which stage of the colony life cycle fungiculture is initiated, and whether the- symbiont fungi serve as food for the ant queen. To clarify these questions, we investigated four Azteca ant species inhabiting three different Cecropia species (C. insignis, C. obtusifolia, and C. peltata). We analysed an rRNA gene fragment from 52 fungal patches produced by founding queens and compared them with those from established Azteca colonies (n = 54). The infrabuccal pockets of winged queens were dissected to investigate whether young queens carry fungi from their mother colony. Additionally, 15N labelling experiments were done to verify whether the queen feeds on the patches until she is nourished by her first worker offspring. We infer from the results that the fungi cultivated in hollow plant structures are transferred from the parental colony of the young queen. First, fungal genotypes/OTU diversity was not significantly different between foundress queen patches and established colonies, and second, hyphal parts were discovered in the infrabuccal pockets of female alates. We could show that fungiculture already starts before queens lay their eggs, and that the queens do not feed on fungal patch material but feed it to the larvae. Our findings suggest that fungiculture may be crucial for successful colony founding of arboreal ants in the tropics. PMID- 29466382 TI - Mating and aggregative behaviors among basal hexapods in the Early Cretaceous. AB - Among the many challenges in paleobiology is the inference and reconstruction of behaviors that rarely, if ever, leave a physical trace on the environment that is suitable for fossilization. Of particular significance are those behaviors tied to mating and courtship, individual interactions critical for species integrity and continuance, as well as those for dispersal, permitting the taxon to expand its distribution as well as access new habitats in the face of local or long-term environmental change. In this context, two recently discovered fossils from the Early Cretaceous amber of Spain (ca. 105 mya) give a detailed view of otherwise fleeting ethologies in Collembola. These occurrences are phylogenetically spaced across the class, and from species representing the two major clades of springtails-Symphypleona and Entomobryomorpha. Specifically, we report unique evidence from a symphypleonan male (Pseudosminthurides stoechus Sanchez-Garcia & Engel, 2016) with modified antennae that may have functioned as a clasping organ for securing females during mating on water's surface, and from an aggregation of entomobryomorphan individuals (Proisotoma communis Sanchez-Garcia & Engel, 2016) purportedly representing a swarming episode on the forest floor. We demonstrate that the mating behavioral repertoire in P. stoechus, which is associated with considerable morphological adaptations, likely implied elaborate courtship and maneuvering for guarantee sperm transfer in an epineustic species. These discoveries reveal significant behaviors consistent with modern counterparts and a generalized stasis for some ancient hexapod ethologies associated with complex mating and courtship and social or pre-social aggregations, so critical to specific constancy and dispersal. PMID- 29466384 TI - Archaeological application of airborne LiDAR to examine social changes in the Ceibal region of the Maya lowlands. AB - Although the application of LiDAR has made significant contributions to archaeology, LiDAR only provides a synchronic view of the current topography. An important challenge for researchers is to extract diachronic information over typically extensive LiDAR-surveyed areas in an efficient manner. By applying an architectural chronology obtained from intensive excavations at the site center and by complementing it with surface collection and test excavations in peripheral zones, we analyze LiDAR data over an area of 470 km2 to trace social changes through time in the Ceibal region, Guatemala, of the Maya lowlands. We refine estimates of structure counts and populations by applying commission and omission error rates calculated from the results of ground-truthing. Although the results of our study need to be tested and refined with additional research in the future, they provide an initial understanding of social processes over a wide area. Ceibal appears to have served as the only ceremonial complex in the region during the transition to sedentism at the beginning of the Middle Preclassic period (c. 1000 BC). As a more sedentary way of life was accepted during the late part of the Middle Preclassic period and the initial Late Preclassic period (600 300 BC), more ceremonial assemblages were constructed outside the Ceibal center, possibly symbolizing the local groups' claim to surrounding agricultural lands. From the middle Late Preclassic to the initial Early Classic period (300 BC-AD 300), a significant number of pyramidal complexes were probably built. Their high concentration in the Ceibal center probably reflects increasing political centralization. After a demographic decline during the rest of the Early Classic period, the population in the Ceibal region reached the highest level during the Late and Terminal Classic periods, when dynastic rule was well established (AD 600-950). PMID- 29466383 TI - Stroke survivors' and informal caregivers' experiences of primary care and community healthcare services - A systematic review and meta-ethnography. AB - OBJECTIVE: To describe and explain stroke survivors and informal caregivers' experiences of primary care and community healthcare services. To offer potential solutions for how negative experiences could be addressed by healthcare services. DESIGN: Systematic review and meta-ethnography. DATA SOURCES: Medline, CINAHL, Embase and PsycINFO databases (literature searched until May 2015, published studies ranged from 1996 to 2015). ELIGIBILITY CRITERIA: Primary qualitative studies focused on adult community-dwelling stroke survivors' and/or informal caregivers' experiences of primary care and/or community healthcare services. DATA SYNTHESIS: A set of common second order constructs (original authors' interpretations of participants' experiences) were identified across the studies and used to develop a novel integrative account of the data (third order constructs). Study quality was assessed using the Critical Appraisal Skills Programme checklist. Relevance was assessed using Dixon-Woods' criteria. RESULTS: 51 studies (including 168 stroke survivors and 328 caregivers) were synthesised. We developed three inter-dependent third order constructs: (1) marginalisation of stroke survivors and caregivers by healthcare services, (2) passivity versus proactivity in the relationship between health services and the patient/caregiver dyad, and (3) fluidity of stroke related needs for both patient and caregiver. Issues of continuity of care, limitations in access to services and inadequate information provision drove perceptions of marginalisation and passivity of services for both patients and caregivers. Fluidity was apparent through changing information needs and psychological adaptation to living with long-term consequences of stroke. LIMITATIONS: Potential limitations of qualitative research such as limited generalisability and inability to provide firm answers are offset by the consistency of the findings across a range of countries and healthcare systems. CONCLUSIONS: Stroke survivors and caregivers feel abandoned because they have become marginalised by services and they do not have the knowledge or skills to re-engage. This can be addressed by: (1) increasing stroke specific health literacy by targeted and timely information provision, and (2) improving continuity of care between specialist and generalist services. SYSTEMATIC REVIEW REGISTRATION NUMBER: PROSPERO 2015:CRD42015026602. PMID- 29466385 TI - Adherence to antiretroviral therapy in a clinical cohort of HIV-infected children in East Africa. AB - OBJECTIVE: To describe antiretroviral therapy (ART) adherence and associated factors for a large HIV-infected pediatric cohort followed by sites of the East Africa International Epidemiologic Databases to Evaluate AIDS (IeDEA) consortium. METHODS: This study utilized prospectively collected clinical data from HIV infected children less than 13 years of age who initiated ART within 4 clinical care programs (with 26 clinical sites) in Kenya, Uganda, and Tanzania and were followed for up to 6 years. Programs used one of 3 adherence measures, including 7-day quantitative recall, 7-day categorical recall, and clinician pill assessments. We fit a hierarchical, three-level, logistic-regression model to examine adherence, with observations nested within patient, and patients within the 26 sites providing pediatric HIV data to this analysis. RESULTS: In East Africa, 3,304 children, 52.0% male, were enrolled in care and were subsequently observed for a median of 92 weeks (inter-quartile range [IQR] 50.3-145.0 weeks). Median age at ART initiation was 5.5 years ([IQR] 3.0-8.5 years). "Good" adherence, as reported by each clinic's measures, was extremely high, remaining on average above 90% throughout all years of follow-up. Longer time on ART was associated with higher adherence (adjusted Odds Ratio-aOR-per log-transformed week on ART: 1.095, 95% Confidence Interval-CI-[1.052-1.150].) Patients enrolled in higher-volume programs exhibited higher rates of clinician-assessed adherence (aOR per log-500 patients: 1.174, 95% CI [1.108-1.245]). Significant site-level variability in reported adherence was observed (0.28), with even higher variability among patients (0.71). In a sub-analysis, being an orphan at the start of ART was strongly associated with lower ART adherence rates (aOR: 0.919, 95% CI [0.864-0.976]). CONCLUSIONS: Self-reported adherence remained high over a median of 1.8 years in HIV care, but varied according to patient-level and site level factors. Consistent adherence monitoring with validated measures and attention to vulnerable groups is recommended. PMID- 29466386 TI - The Arabidopsis arc5 and arc6 mutations differentially affect plastid morphology in pavement and guard cells in the leaf epidermis. AB - Chloroplasts, or photosynthetic plastids, multiply by binary fission, forming a homogeneous population in plant cells. In Arabidopsis thaliana, the division apparatus (or division ring) of mesophyll chloroplasts includes an inner envelope transmembrane protein ARC6, a cytoplasmic dynamin-related protein ARC5 (DRP5B), and members of the FtsZ1 and FtsZ2 families of proteins, which co-assemble in the stromal mid-plastid division ring (FtsZ ring). FtsZ ring placement is controlled by several proteins, including a stromal factor MinE (AtMinE1). During leaf mesophyll development, ARC6 and AtMinE1 are necessary for FtsZ ring formation and thus plastid division initiation, while ARC5 is essential for a later stage of plastid division. Here, we examined plastid morphology in leaf epidermal pavement cells (PCs) and stomatal guard cells (GCs) in the arc5 and arc6 mutants using stroma-targeted fluorescent proteins. The arc5 PC plastids were generally a bit larger than those of the wild type, but most had normal shapes and were division competent, unlike mutant mesophyll chloroplasts. The arc6 PC plastids were heterogeneous in size and shape, including the formation of giant and mini plastids, plastids with highly developed stromules, and grape-like plastid clusters, which varied on a cell-by-cell basis. Moreover, unique plastid phenotypes for stomatal GCs were observed in both mutants. The arc5 GCs rarely lacked chlorophyll-bearing plastids (chloroplasts), while they accumulated minute chlorophyll-less plastids, whereas most GCs developed wild type-like chloroplasts. The arc6 GCs produced large chloroplasts and/or chlorophyll-less plastids, as previously observed, but unexpectedly, their chloroplasts/plastids exhibited marked morphological variations. We quantitatively analyzed plastid morphology and partitioning in paired GCs from wild-type, arc5, arc6, and atminE1 plants. Collectively, our results support the notion that ARC5 is dispensable in the process of equal division of epidermal plastids, and indicate that dysfunctions in ARC5 and ARC6 differentially affect plastid replication among mesophyll cells, PCs, and GCs within a single leaf. PMID- 29466387 TI - Overexpression of the alfalfa WRKY11 gene enhances salt tolerance in soybean. AB - The WRKY transcription factors play an important role in the regulation of transcriptional reprogramming associated with plant abiotic stress responses. In this study, the WRKY transcription factor MsWRKY11, containing the plant-specific WRKY zinc finger DNA-binding motif, was isolated from alfalfa. The MsWRKY11 gene was detected in all plant tissues (root, stem, leaf, flower, and fruit), with high expression in root and leaf tissues. MsWRKY11 was upregulated in response to a variety of abiotic stresses, including salinity, alkalinity, cold, abscisic acid, and drought. Overexpression of MsWRKY11 in soybean enhanced the salt tolerance at the seedling stage. Transgenic soybean had a better salt-tolerant phenotype, and the hypocotyls were significantly longer than those of wild-type seeds after salt treatment. Furthermore, MsWRKY11 overexpression increased the contents of chlorophyll, proline, soluble sugar, superoxide dismutase, and catalase, but reduced the relative electrical conductivity and the contents of malonaldehyde, H2O2, and O2-. Plant height, pods per plant, seeds per plant, and 100-seed weight of transgenic MsWRKY11 soybean were higher than those of wild type soybean, especially OX2. Results of the salt experiment showed that MsWRKY11 is involved in salt stress responses, and its overexpression improves salt tolerance in soybean. PMID- 29466388 TI - Prospecting for viral natural enemies of the fire ant Solenopsis invicta in Argentina. AB - Metagenomics and next generation sequencing were employed to discover new virus natural enemies of the fire ant, Solenopsis invicta Buren in its native range (i.e., Formosa, Argentina) with the ultimate goal of testing and releasing new viral pathogens into U.S. S. invicta populations to provide natural, sustainable control of this ant. RNA was purified from worker ants from 182 S. invicta colonies, which was pooled into 4 groups according to location. A library was created from each group and sequenced using Illumina Miseq technology. After a series of winnowing methods to remove S. invicta genes, known S. invicta virus genes, and all other non-virus gene sequences, 61,944 unique singletons were identified with virus identity. These were assembled de novo yielding 171 contiguous sequences with significant identity to non-plant virus genes. Fifteen contiguous sequences exhibited very high expression rates and were detected in all four gene libraries. One contig (Contig_29) exhibited the highest expression level overall and across all four gene libraries. Random amplification of cDNA ends analyses expanded this contiguous sequence yielding a complete virus genome, which we have provisionally named Solenopsis invicta virus 5 (SINV-5). SINV-5 is a positive-sense, single-stranded RNA virus with genome characteristics consistent with insect-infecting viruses from the family Dicistroviridae. Moreover, the replicative genome strand of SINV-5 was detected in worker ants indicating that S. invicta serves as host for the virus. Many additional sequences were identified that are likely of viral origin. These sequences await further investigation to determine their origins and relationship with S. invicta. This study expands knowledge of the RNA virome diversity found within S. invicta populations. PMID- 29466389 TI - Mapping integration of midwives across the United States: Impact on access, equity, and outcomes. AB - METHODS: Our multidisciplinary team examined published regulatory data to inform a 50-state database describing the environment for midwifery practice and interprofessional collaboration. Items (110) detailed differences across jurisdictions in scope of practice, autonomy, governance, and prescriptive authority; as well as restrictions that can affect patient safety, quality, and access to maternity providers across birth settings. A nationwide survey of state regulatory experts (n = 92) verified the 'on the ground' relevance, importance, and realities of local interpretation of these state laws. Using a modified Delphi process, we selected 50/110 key items to include in a weighted, composite Midwifery Integration Scoring (MISS) system. Higher scores indicate greater integration of midwives across all settings. We ranked states by MISS scores; and, using reliable indicators in the CDC-Vital Statistics Database, we calculated correlation coefficients between MISS scores and maternal-newborn outcomes by state, as well as state density of midwives and place of birth. We conducted hierarchical linear regression analysis to control for confounding effects of race. RESULTS: MISS scores ranged from lowest at 17 (North Carolina) to highest at 61 (Washington), out of 100 points. Higher MISS scores were associated with significantly higher rates of spontaneous vaginal delivery, vaginal birth after cesarean, and breastfeeding, and significantly lower rates of cesarean, preterm birth, low birth weight infants, and neonatal death. MISS scores also correlated with density of midwives and access to care across birth settings. Significant differences in newborn outcomes accounted for by MISS scores persisted after controlling for proportion of African American births in each state. CONCLUSION: The MISS scoring system assesses the level of integration of midwives and evaluates regional access to high quality maternity care. In the United States, higher MISS Scores were associated with significantly higher rates of physiologic birth, less obstetric interventions, and fewer adverse neonatal outcomes. PMID- 29466390 TI - The role of complement activation in rhabdomyolysis-induced acute kidney injury. AB - Rhabdomyolysis (RM) may cause kidney damage and results primarily in acute kidney injury (AKI). Complement is implicated in the pathogenesis of renal diseases and ischemia-reperfusion injury (IRI), but the role of complement, especially its activation pathway(s) and its effect in RM-induced AKI, is not clear. This study established a rat model of AKI induced by RM via intramuscular treatment with glycerol. Cobra venom factor (CVF) was administered via tail vein injection to deplete complement 12 h prior to intramuscular injection of glycerol. We found that the complement components, including complement 3 (C3), C1q, MBL-A, factor B(fB), C5a, C5b-9, and CD59, were significantly increased in rat kidneys after intramuscular glycerol administration. However, the levels of serum BUN and Cr, renal tubular injury scores, and the number of TUNEL-positive cells decreased significantly in the CVF+AKI group. These results suggest that complement plays an important role in RM-induced AKI and that complement depletion may improve renal function and decrease renal tissue damage by reducing the inflammatory response and apoptosis. PMID- 29466391 TI - A standardised equine-based welfare assessment tool used for six years in low and middle income countries. AB - The majority of horses, donkeys and mules (equids) are in low- and middle-income countries, where they remain a key source of labour in the construction, agriculture and tourism industries, as well as supporting households daily through transporting people and staple goods. Globally, approximately 600 million people depend on working equids for their livelihood. Safeguarding the welfare of these animals is essential for them to work, as well as for the intrinsic value of the animal's quality of life. In order to manage animal welfare, it must be measured. Over the past decade, welfare assessment methodologies have emerged for different species, more recently for equids. We present the Standardised Equine Based Welfare Assessment Tool (SEBWAT) for working equids. The tool is unique, in that it has been applied in practice by a non-governmental organisation (NGO) for six years across Low-Middle-Income Countries (LMICs). We describe the revision of the tool from an original to a second version, the tool methodology and user training process and how data collection and analysis have been conducted. We describe its application at scale, where it has been used more than 71,000 times in 11 countries. Case study examples are given from the tool being used for a needs assessment in Guatemala and monitoring welfare change in Jordan. We conclude by describing the main benefits and limitations for how the tool could be applied by others on working equids in LMICs and how it may develop in the future. PMID- 29466392 TI - Differences between co-cultures and monocultures in testing the toxicity of particulate matter derived from log wood and pellet combustion. AB - BACKGROUND: In vitro studies with monocultures of human alveolar cells shed deeper knowledge on the cellular mechanisms by which particulate matter (PM) causes toxicity, but cannot account for mitigating or aggravating effects of cell cell interactions on PM toxicity. METHODS: We assessed inflammation, oxidative stress as well as cytotoxic and genotoxic effects induced by PM from the combustion of different types of wood logs and softwood pellets in three cell culture setups: two monocultures of either human macrophage-like cells or human alveolar epithelial cells, and a co-culture of these two cell lines. The adverse effects of the PM samples were compared between these setups. RESULTS: We detected clear differences in the endpoints between the mono- and co-cultures. Inflammatory responses were more diverse in the macrophage monoculture and the co culture compared to the epithelial cells where only an increase of IL-8 was detected. The production of reactive oxygen species was the highest in epithelial cells and macrophages seemed to have protective effects against oxidative stress from the PM samples. With no metabolically active cells at the highest doses, the cytotoxic effects of the PM samples from the wood log combustion were far more pronounced in the macrophages and the co-culture than in the epithelial cells. All samples caused DNA damage in macrophages, whereas only beech and spruce log combustion samples caused DNA damage in epithelial cells. The organic content of the samples was mainly associated with cytotoxicity and DNA damage, while the metal content of the samples correlated with the induction of inflammatory responses. CONCLUSIONS: All of the tested PM samples induce adverse effects and the chemical composition of the samples determines which pathway of toxicity is induced. In vitro testing of the toxicity of combustion-derived PM in monocultures of one cell line, however, is inadequate to account for all the possible pathways of toxicity. PMID- 29466394 TI - A hybrid intelligent method for three-dimensional short-term prediction of dissolved oxygen content in aquaculture. AB - A precise predictive model is important for obtaining a clear understanding of the changes in dissolved oxygen content in crab ponds. Highly accurate interval forecasting of dissolved oxygen content is fundamental to reduce risk, and three dimensional prediction can provide more accurate results and overall guidance. In this study, a hybrid three-dimensional (3D) dissolved oxygen content prediction model based on a radial basis function (RBF) neural network, K-means and subtractive clustering was developed and named the subtractive clustering (SC)-K means-RBF model. In this modeling process, K-means and subtractive clustering methods were employed to enhance the hyperparameters required in the RBF neural network model. The comparison of the predicted results of different traditional models validated the effectiveness and accuracy of the proposed hybrid SC-K-means RBF model for three-dimensional prediction of dissolved oxygen content. Consequently, the proposed model can effectively display the three-dimensional distribution of dissolved oxygen content and serve as a guide for feeding and future studies. PMID- 29466393 TI - The effect of low and high-intensity cycling in diesel exhaust on flow-mediated dilation, circulating NOx, endothelin-1 and blood pressure. AB - INTRODUCTION: Exposure to air pollution impairs aspects of endothelial function such as flow-mediated dilation (FMD). Outdoor exercisers are frequently exposed to air pollution, but how exercising in air pollution affects endothelial function and how these effects are modified by exercise intensity are poorly understood. OBJECTIVES: Therefore, the purpose of this study was to determine the effects of low-intensity and high-intensity cycling with diesel exhaust (DE) exposure on FMD, blood pressure, plasma nitrite and nitrate (NOx) and endothelin 1. METHODS: Eighteen males performed 30-minute trials of low or high-intensity cycling (30% and 60% of power at VO2peak) or a resting control condition. For each subject, each trial was performed once while breathing filtered air (FA) and once while breathing DE (300ug/m3 of PM2.5, six trials in total). Preceding exposure, immediately post-exposure, 1 hour and 2 hours post-exposure, FMD, blood pressure and plasma endothelin-1 and NOx concentrations were measured. Data were analyzed using repeated-measures ANOVA and linear mixed model. RESULTS: Following exercise in DE, plasma NOx significantly increased and was significantly greater than FA (p<0.05). Two hours following DE exposure, endothelin-1 was significantly less than FA (p = 0.037) but exercise intensity did not modify this response. DE exposure did not affect FMD or blood pressure. CONCLUSION: Our results suggest that exercising in DE did not adversely affect plasma NOX, endothelin-1, FMD and blood pressure. Therefore, recommendations for healthy individuals to moderate or avoid exercise during bouts of high pollution appear to have no acute protective effect. PMID- 29466395 TI - Dynamics of monocytic HLA-DR expression differs between bacterial etiologies during the course of bloodstream infection. AB - OBJECTIVE: In the pathogenesis of sepsis, activation of both pro- and anti inflammatory responses are key components, but knowledge is lacking on the association between bacterial etiology and development of dysregulated responses with sustained immunosuppression. The aim of this study was to evaluate how the immunosupression marker HLA-DR on monocytes (mHLA-DR) is associated with bacterial etiology and markers of inflammation during the clinical trajectory of bloodstream infection (BSI). METHODS: Ninety-one adults, predominantly non-ICU patients, with BSI caused by Streptococcus pneumoniae (n = 27), Staphylococcus aureus (n = 22), Escherichia coli/Klebsiella pneumoniae (n = 23), and other species (n = 19) were prospectively included, and sampled on admission (day 0) and on days 1-2, 3, 7+/-1, 14+/-2, and 28+/-4. RESULTS: The dynamics of mHLA-DR, measured by flow cytometry, differed significantly between etiology groups (p<0.001). Patients with S. pneumoniae and S. aureus BSI demonstrated low initial mHLA-DR, with the S. aureus group showing delayed recovery over time. Eleven patients (55% S. aureus) had negative outcome (secondary bacteremia or death) and they demonstrated sustained C-reactive protein elevation, neutrophilia, lymphocytopenia, and loss of mHLA-DR. CONCLUSIONS: Dynamics of mHLA-DR varied according to the bacterial etiology of infection, with delayed recovery in patients with S. aureus BSI. Patients with negative outcome showed sustained CRP elevation, neutrophilia, lymphocytopenia, and low levels of mHLA-DR, supporting the theory of a dysregulated host response with persistent inflammation and immunosuppression in late stages of deleterious sepsis. PMID- 29466396 TI - Hydrogen sulfide is expressed in the human and the rat cultured nucleus pulposus cells and suppresses apoptosis induced by hypoxia. AB - Apoptosis plays pivotal role in the pathogenesis of degenerative disc diseases, which is the primary contributor to low back pain. Although the role of hydrogen sulfide (H2S) in cell apoptosis is well appreciated, the effects and mechanism that H2S regulates the program death of intervertebral disc cell are not yet elucidated. In this study, we utilized the nucleus pulposus (NP) from patients with lumbar disc herniation to investigate the relationship between endogenous H2S and NP cells apoptosis in human. Furthermore, we analyzed primary rat NP cells to study the effects of exogenous H2S on hypoxia induced cell apoptosis. Human NP samples were obtained from patients with lumbar disc herniation and were divided into uncontained and contained herniation groups. Using immunohistochemistry staining and sulphur-sensitive electrode, we detected the expression of cystathionine-beta-synthase (CBS) and cystathionine gamma-lyase (CSE), as well as the production of endogenous H2S in human NP. Tunel staining showed increased apoptosis in NP from herniated disc; and there was significant correlation between H2S generation and apoptosis in human NP. CoCl2 was then used to induce hypoxia in cultured primary rat NP cells. Annexin V staining indicated that exogenous NaHS attenuated hypoxia induced apoptosis in rat NP cells. Furthermore, hypoxia significantly increased the levels of multiple apoptosis associated proteins (Fas, Cytochromes C, Caspase 9 and cleaved-Caspase-3) in cells, which were eliminated by NaHS. Our study demonstrates the presence of endogenous H2S in human intervertebral disc; and the endogenous H2S generation rate is associated with NP apoptosis in herniated disc. In vitro study showes exogenous H2S donor attenuates hypoxia induced apoptosis in primary rat NP cells. Thus, our work provides insights that H2S may have beneficial effects in treating degenerative disc diseases. PMID- 29466397 TI - A new disclosure index for Non-Governmental Organizations. AB - Website of Non-governmental organization (NGO) is a focal medium of sharing information in response to transparency demands and addressing trust deficits between stakeholders. Many researchers have proposed accountability approaches to measure information sharing trends through websites. This article discusses a new index to measure online disclosure trends along with the theoretical properties of the index and a practical application of data from NGOs working in Pakistan. The websites have been coded in 2016. Results show that NGOs with branch offices have better disclosure scores than single-office NGOs, and international NGOs score better than local NGOs. NGOs that are more often the subject of newspaper reports have better disclosure trends. PMID- 29466398 TI - Complex genetic patterns in human arise from a simple range-expansion model over continental landmasses. AB - Although it is generally accepted that geography is a major factor shaping human genetic differentiation, it is still disputed how much of this differentiation is a result of a simple process of isolation-by-distance, and if there are factors generating distinct clusters of genetic similarity. We address this question using a geographically explicit simulation framework coupled with an Approximate Bayesian Computation approach. Based on six simple summary statistics only, we estimated the most probable demographic parameters that shaped modern human evolution under an isolation by distance scenario, and found these were the following: an initial population in East Africa spread and grew from 4000 individuals to 5.7 million in about 132 000 years. Subsequent simulations with these estimates followed by cluster analyses produced results nearly identical to those obtained in real data. Thus, a simple diffusion model from East Africa explains a large portion of the genetic diversity patterns observed in modern humans. We argue that a model of isolation by distance along the continental landmasses might be the relevant null model to use when investigating selective effects in humans and probably many other species. PMID- 29466399 TI - Acute basilar thrombosis: Recanalization following intravenous thrombolysis is dependent on thrombus length. AB - INTRODUCTION: We investigated whether thrombus length measured in Computed Tomography Angiography (CTA) is predictive of the success rate of intravenous thrombolysis (IVT) in acute basilar occlusion and whether recanalization can be achieved by additional mechanical endovascular thrombectomy. METHODS: In 51 patients with acute basilar thrombosis thrombus length was measured on CTA images before intravenous thrombolysis (IVT) with rt-PA was started. After 114 minutes on average success of IVT was evaluated either by CTA or DSA. Patients with persistent basilar occlusion and no major brainstem infarction on CT underwent endovascular recanalization. RESULTS: 87% of patients had no recanalization of basilar artery after IVT alone. The average thrombus length was 15 mm in patients with persistent basilar occlusion after IVT and 7 mm in patients with recanalization after IVT. Thrombi longer than 13 mm did not resolve after IVT alone and 80% of thrombi shorter than 13 mm did not resolve either. 41 patients were transferred to endovascular recanalization; endovascular therapy was performed successfully in 90% (37 / 41). CONCLUSIONS: Recanalization rates in acute basilar occlusion after IVT alone are low and dependent on thrombus length. Additional mechanical endovascular thrombectomy showed to be a very successful recanalization therapy. PMID- 29466400 TI - Insights into the origin of the high variability of multivalent-meiotic associations in holocentric chromosomes of Tityus (Archaeotityus) scorpions. AB - Scorpions represent an intriguing group of animals characterized by a high incidence of heterozygous chromosomal rearrangements. In this work, we examined six species of Tityus (Archaeotityus) from Brazilian fauna with a particular focus on elucidating the rearrangements responsible for the intraspecific variability of diploid number and the presence of long chromosomal chains in meiosis. To access any interpopulation diversity, we also studied individuals from four species representing distinct localities. Most species demonstrated intraspecific polymorphism in diploid number (2n = 19 and 2n = 20 in T. clathratus, T. mattogrossensis, and T. pusillus, 2n = 16, 2n = 17 and 2n = 18 in T. paraguayensis, and 2n = 16 and 2n = 24 in T. silvestris) and multi-chromosomal associations during meiosis I, which differed even among individuals with the same chromosome number. In some species, the heterozygous rearrangements were not fixed, resulting such as in Tityus clathatrus, in 11 different chromosomal configurations recognized within a same population. Based on meiotic chromosome behaviour, we suggested that independent rearrangements (fusion/fission and reciprocal translocations), occurring in different combinations, originated the multi-chromosomal chains. To evaluate the effects of these chromosome chains on meiotic segregation, we applied the chi-square test in metaphase II cells. The non-significant occurrence of aneuploid nuclei indicated that non-disjunction was negligible in specimens bearing heterozygous rearrangements. Finally, based on our analysis of many chromosome characteristics, e.g., holocentricity, achiasmate meiosis, endopolyploidy, ability to segregate heterosynaptic or unsynapsed chromosomes, (TTAGG)n sequence located in terminal regions of rearranged chromosomes, we suggest that the maintenance of multi-chromosomal associations may be evolutionarily advantageous for these species.

AB - Common vampire bats (Desmodus rotundus) occur throughout much of South America to northern Mexico. Vampire bats have not been documented in recent history in the United States, but have been documented within about 50 km of the U.S. state of Texas. Vampire bats feed regularly on the blood of mammals and can transmit rabies virus to native species and livestock, causing impacts on the health of prey. Thus cattle producers, wildlife management agencies, and other stakeholders have expressed concerns about whether vampire bats might spread into the southern United States. On the other hand, concerns about vampire-borne rabies can also result in wanton destruction at bat roosts in areas occupied by vampire bats, but also in areas not known to be occupied by this species. This can in turn negatively affect some bat roosts, populations, and species that are of conservation concern, including vampire bats. To better understand the current and possible future distribution of vampire bats in North America and help mitigate future cattle management problems, we used 7,094 vampire bat occurrence records from North America and species distribution modeling (SDM) to map the potential distribution of vampire bats in North America under current and future climate change scenarios. We analysed and mapped the potential distribution of this species using 5 approaches to species distribution modeling: logistic regression, multivariate adaptive regression splines, boosted regression trees, random forest, and maximum entropy. We then projected these models into 17 "worst case" future climate scenarios for year 2070 to generate hypotheses about how the vampire bat distribution in North America might change in the future. Of the variables used in this analysis, minimum temperature of the coldest month had the highest variable importance using all 5 SDM approaches. These results suggest two potential near-future routes of vampire bat dispersal into the U.S., one via southern Texas, and a second into southern Florida. Some of our SDM models support the hypothesis that suitable habitat for vampire bats may currently exist in parts of the Mexico-U.S. borderlands, including extreme southern portions of Texas, as well as in southern Florida. However, this analysis also suggests that extensive expansion into the south-eastern and south-western U.S. over the coming ~60 years appears unlikely.

AB - Much of the Human Factors research into vehicle automation has focused on driver responses to critical scenarios where a crash might occur. However, there is less knowledge about the effects of vehicle automation on drivers' behaviour during non-critical take-over situations, such as driver-initiated lane-changing or overtaking. The current driving simulator study, conducted as part of the EC funded AdaptIVe project, addresses this issue. It uses a within-subjects design to compare drivers' lane-changing behaviour in conventional manual driving, partially automated driving (PAD) and conditionally automated driving (CAD). In PAD, drivers were required to re-take control from an automated driving system in order to overtake a slow moving vehicle, while in CAD, the driver used the indicator lever to initiate a system-performed overtaking manoeuvre. Results showed that while drivers' acceptance of both the PAD and CAD systems was high, they generally preferred CAD. A comparison of overtaking positions showed that drivers initiated overtaking manoeuvres slightly later in PAD than in manual driving or CAD. In addition, when compared to conventional driving, drivers had higher deviations in lane positioning and speed, along with higher lateral accelerations during lane changes following PAD. These results indicate that even in situations which are not time-critical, drivers' vehicle control after automation is degraded compared to conventional driving. PMID- 29466403 TI - Estimating the burden of rabies in Ethiopia by tracing dog bite victims. AB - In developing countries where financial resources are limited and numerous interests compete, there is a need for quantitative data on the public health burden and costs of diseases to support intervention prioritization. This study aimed at estimating the health burden and post-exposure treatment (PET) costs of canine rabies in Ethiopia by an investigation of exposed human cases. Data on registered animal bite victims during the period of one year were collected from health centers in three districts, i.e. Bishoftu, Lemuna-bilbilo and Yabelo, to account for variation in urban highland and lowland areas. This data collection was followed by an extensive case search for unregistered victims in the same districts as the registered cases. Victims were visited and questioned on their use of PET, incurred treatment costs and the behavioral manifestations of the animal that had bitten them. Based on the collected data PET costs were evaluated by financial accounting and the health burden was estimated in Disability Adjusted Life Years (DALYs). In total 655 animal bite cases were traced of which 96.5% was caused by dog bites. 73.6% of the biting dogs were suspected to be potentially rabid dog. Annual suspected rabid dog exposures were estimated per evaluated urban, rural highland and rural lowland district at, respectively, 135, 101 and 86 bites, which led, respectively, to about 1, 4 and 3 deaths per 100,000 population. In the same district order average costs per completed PET equaled to 23, 31 and 40 USD, which was significantly higher in rural districts. Extrapolation of the district results to the national level indicated an annual estimate of approximately 3,000 human deaths resulting in about 194,000 DALYs per year and 97,000 exposed persons requiring on average 2 million USD treatment costs per year countrywide. These estimations of the burden of rabies to the Ethiopian society provide decision makers insights into the potential benefits of implementing effective interventions. PMID- 29466404 TI - Antioxidant genes of plants and fungal pathogens are distinctly regulated during disease development in different Rhizoctonia solani pathosystems. AB - Biotic stress, as a result of plant-pathogen interactions, induces the accumulation of reactive oxygen species in the cells, causing severe oxidative damage to plants and pathogens. To overcome this damage, both the host and pathogen have developed antioxidant systems to quench excess ROS and keep ROS production and scavenging systems under control. Data on ROS-scavenging systems in the necrotrophic plant pathogen Rhizoctonia solani are just emerging. We formerly identified vitamin B6 biosynthetic machinery of R. solani AG3 as a powerful antioxidant exhibiting a high ability to quench ROS, similar to CATALASE (CAT) and GLUTATHIONE S-TRANSFERASE (GST). Here, we provide evidence on the involvement of R. solani vitamin B6 biosynthetic pathway genes; RsolPDX1 (KF620111.1), RsolPDX2 (KF620112.1), and RsolPLR (KJ395592.1) in vitamin B6 de novo biosynthesis by yeast complementation assays. Since gene expression studies focusing on oxidative stress responses of both the plant and the pathogen following R. solani infection are very limited, this study is the first coexpression analysis of genes encoding vitamin B6, CAT and GST in plant and fungal tissues of three pathosystems during interaction of different AG groups of R. solani with their respective hosts. The findings indicate that distinct expression patterns of fungal and host antioxidant genes were correlated in necrotic tissues and their surrounding areas in each of the three R. solani pathosystems: potato sprout-R. solani AG3; soybean hypocotyl-R. solani AG4 and soybean leaves-R. solani AG1-IA interactions. Levels of ROS increased in all types of potato and soybean tissues, and in fungal hyphae following infection of R. solani AGs as determined by non-fluorescence and fluorescence methods using H2DCF-DA and DAB, respectively. Overall, we demonstrate that the co-expression and accumulation of certain plant and pathogen ROS-antioxidant related genes in each pathosystem are highlighted and might be critical during disease development from the plant's point of view, and in pathogenicity and developing of infection structures from the fungal point of view. PMID- 29466405 TI - Molecular phylogeny of Panicum s. str. (Poaceae, Panicoideae, Paniceae) and insights into its biogeography and evolution. AB - Panicum sensu stricto is a genus of grasses (Poaceae) with nearly, according to this study, 163 species distributed worldwide. This genus is included in the subtribe Panicinae together with Louisiella, the latter with 2 species. Panicum and subtribe Panicinae are characterized by including annual or perennial taxa with open and lax panicles, and spikelets with the lower glume reduced; all taxa also share a basic chromosome number of x = 9 and a Kranz leaf blade anatomy typical of the NAD-me subtype photosynthetic pathway. Nevertheless, the phylogenetic placements of many Panicum species, and the circumscription of the genus, remained untested. Therefore, phylogenetic analyses were conducted using sequence data from the ndhF plastid region, in an extensive worldwide sampling of Panicum and related genera, in order to infer evolutionary relationships and to provide a phylogenetic framework to review the classification of the genus. Diversification times, historical biogeography and evolutionary patterns of the life history (annual vs. perennial) in the subtribe and Panicum were also studied. Results obtained provide strong support for a monophyletic Panicum including 71 species and 7 sections, of which sections Arthragrostis and Yakirra are new in the genus; 7 new combinations are made here. Furthermore, 32 species traditionally assigned to Panicum were excluded from the genus, and discussed in other subtribes of Paniceae. Our study suggested that early diversification in subtribe Panicinae and Panicum occurred through the Early-Mid Miocene in the Neotropics, while the subsequent diversification of its sections mainly occurred in the Late Miocene-Pleistocene, involving multiple dispersals to all continents. Our analyses also showed that transition rates and changes between annual and perennial life history in Panicum were quite frequent, suggesting considerable lability of this trait. Changes of the life history, together with C4 photosynthesis, and the multiple dispersal events since the Mid Miocene, seem to have facilitated a widespread distribution of the genus. All these findings contribute to a better understanding of the systematics and evolution of Panicum. PMID- 29466406 TI - Increased fecal calprotectin levels in Crohn's disease correlate with elevated serum Th1- and Th17-associated cytokines. AB - BACKGROUND: Patient-reported symptoms and endoscopic disease activity do not correlate well in Crohn's disease (CD). This warrants the need for reliable biomarkers to early detect active intestinal inflammation. Currently, the fecal calprotectin level is the most commonly used biomarker for inflammatory activity in CD. However, the diagnostic accuracy of the fecal calprotectin level is not fully efficacious and diagnosis may be further improved by the identification of other biomarkers for active CD. Here, we studied the association of a variety of serum disease markers with fecal calprotectin levels in CD patients. METHODS: 39 CD patients were included and subdivided into 'normal' (defined as < 200 mg/kg feces) and 'increased' (defined as > 200 mg/kg feces) fecal calprotectin level groups. Serum levels of 37 different cytokines, chemokines and markers for angiogenesis and vascular injury were quantified by an electrochemiluminescence multiplex assay (V-PLEX Human Biomarker 40-Plex Kit of Meso Scale Discovery (r)). Correlations between individual biomarkers and the fecal calprotectin level were assessed using Spearman's correlation coefficient (rho). RESULTS: A highly significant positive correlation was observed between the pro-inflammatory serum cytokines IFN-gamma and CRP and fecal calprotectin levels (P < 0.01). Moreover, fecal calprotectin levels showed a significant positive correlation with IL-6, TNF-beta, SAA and IL-17A (P < 0.05). CONCLUSION: We show that a positive correlation exists between multiple serum Th1- and Th17-associated cytokines and the fecal calprotectin level. These cytokines and CRP may serve as additional biomarkers for determining disease activity and evaluating treatment response in CD. Ultimately, this may result in more efficient treatment of active disease in CD patients and prevention of complications. PMID- 29466407 TI - A scale assessing doctor-patient communication in a context of acute conditions based on a systematic review. AB - BACKGROUND: There is no validated generic tool to measure Doctor-Patient Communication (DPC) in a context of acute conditions. OBJECTIVE: To create and validate such a scale in a real population. MATERIALS AND METHOD: We performed a systematic review of validated DPC scales available in English. From these, using a theoretical model based on a multidisciplinary approach, we selected pertinent items that met the inclusion criteria and included them in a simple questionnaire. This tool based on a synthesis of the literature was then validated in a prospective study in two hospital emergency departments. RESULTS: We found 22 pertinent questionnaires and scoring systems. From these, we extracted items and built a scale based on 15 questions with graded responses (Likert from 1 to 4). The mean time for questionnaire completion was 3 minutes. We included 189 adults and adolescents in the study and analyzed complete responses to the questionnaire by 149 patients, gathered over the phone one week after their consultation. The scale had high internal consistency (Cronbach's alpha = 0.89) and good external validity. Two questions were removed due to redundancy giving a scale based on 13 questions. CONCLUSIONS: We have created an easy-to-use and validated generic questionnaire to assess DPC in a context of acute conditions, usable both in clinical research and in routine practice. PMID- 29466408 TI - The clinical characteristics of adults with rheumatic heart disease in Yangon, Myanmar: An observational study. AB - BACKGROUND: Rheumatic heart disease (RHD) is a major cause of premature death in low and middle-income countries. The greatest barrier to RHD control is neglect of the disease in national health policies and a lack of prevalence data that might inform control efforts. Myanmar is making remarkable progress against many infectious diseases, but there are almost no data to define the clinical burden of RHD in the country. This prospective audit was performed in an adult medical ward of a tertiary-referral hospital in Yangon, to gain an insight into the prevalence of RHD in Myanmar. PRINCIPAL FINDINGS: All patients admitted to the ward between May 1, 2016 and April 30, 2017 were eligible for enrolment. RHD was confirmed in 96 patients who were admitted on 134 occasions, representing 1.1% of the 12,172 adult medical admissions during the study period. This compared with 410 (3.4%) admissions with HIV and 14 (0.1%) with malaria. Patients with RHD had a median age of 44 years (interquartile range: 35-59); 70 (73%) were female. Only one patient had ever had surgery despite 79 (82%) meeting criteria for intervention; 54 (56%) patients were not receiving any regular clinician review. Prior to hospitalisation only 18 (19%) patients were receiving regular penicillin. Only 8 (19%) of the 42 women <50 years were using contraception. Of 49 patients who had been hospitalised previously, 22 (45%) were receiving no regular therapy. During the study three (3.1%) patients died, and 28 (29%) were lost to follow-up. Of the 65 (68%) alive and retained in care, 21 (32%) were still experiencing moderate-severe RHD-related symptoms at the study's end. CONCLUSIONS: There is a significant and unmet clinical burden of RHD in Myanmar. A national RHD programme would improve patient care, reducing morbidity and mortality from this preventable disease. PMID- 29466409 TI - IL-7 treatment augments and prolongs sepsis-induced expansion of IL-10-producing B lymphocytes and myeloid-derived suppressor cells. AB - Immunological dysregulation in sepsis is associated with often lethal secondary infections. Loss of effector cells and an expansion of immunoregulatory cell populations both contribute to sepsis-induced immunosuppression. The extent and duration of this immunosuppression are unknown. Interleukin 7 (IL-7) is important for the maintenance of lymphocytes and can accelerate the reconstitution of effector lymphocytes in sepsis. How IL-7 influences immunosuppressive cell populations is unknown. We have used the mouse model of peritoneal contamination and infection (PCI) to investigate the expansion of immunoregulatory cells as long-term sequelae of sepsis with or without IL-7 treatment. We analysed the frequencies and numbers of regulatory T cells (Tregs), double negative T cells, IL-10 producing B cells and myeloid-derived suppressor cells (MDSCs) for 3.5 months after sepsis induction. Sepsis induced an increase in IL-10+ B cells, which was enhanced and prolonged by IL-7 treatment. An increased frequency of MDSCs in the spleen was still detectable 3.5 months after sepsis induction and this was more pronounced in IL-7-treated mice. MDSCs from septic mice were more potent at suppressing T cell proliferation than MDSCs from control mice. Our data reveal that sepsis induces a long lasting increase in IL-10+ B cells and MDSCs. Late-onset IL-7 treatment augments this increase, which should be relevant for clinical interventions. PMID- 29466410 TI - Familial patterning and prevalence of male androphilia among Istmo Zapotec men and muxes. AB - Male androphilia (i.e., male sexual attraction to other adult males) is known to cluster within families. Some studies demonstrate that male androphilia clusters in both the paternal and maternal familial lines, whereas other studies demonstrated that it clusters only in the latter. Most of these studies were conducted in Euro-American populations where fertility is low and the sexual orientation of male relatives can sometimes be difficult to ascertain. These two factors can potentially confound the results of such studies. To address these limitations, we examined the familial patterning of male androphilia among the Istmo Zapotec of Oaxaca, Mexico--a high fertility, non-Euro-American population where androphilic males are known locally as muxes, a third gender category. The Istmo Zapotec recognize two types of muxes--muxe gunaa and muxe nguiiu--who typify the transgender and cisgender forms of male androphilia, respectively. We compared the familial patterning of male androphilia between muxe gunaa and muxe nguiiu, as well as between gynephilic men and muxes (both cisgender and transgender forms combined). Istmo Zapotec muxe gunaa and muxe nguiiu exhibit similar familial patterning of male androphilia. Overall, muxes were characterized by significantly more muxe relatives than gynephilic men. This familial patterning was equivalent in both the paternal and maternal lines of muxes. The population prevalence rate of male androphilia was estimated to fall between 3.37-6.02% in the Istmo Zapotec. This is the first study that has compared cisgender and transgender androphilic males from the same high fertility population and demonstrated that the two do not differ with respect to the familial patterning of male androphilia. PMID- 29466411 TI - Molecular epidemiology of tuberculosis in Tasmania and genomic characterisation of its first known multi-drug resistant case. AB - BACKGROUND: The origin and spread of tuberculosis (TB) in Tasmania and the types of strains of Mycobacterium tuberculosis complex (MTBC) present in the population are largely unknown. OBJECTIVE: The aim of this study was to perform the first genomic analysis of MTBC isolates from Tasmania to better understand the epidemiology of TB in the state. METHODS: Whole-genome sequencing was performed on cultured isolates of MTBC collected from 2014-2016. Single-locus variant analysis was applied to determine the phylogeny of the isolates and the presence of drug-resistance mutations. The genomic data were then cross-referenced against public health surveillance records on each of the cases. RESULTS: We determined that 83.3% of TB cases in Tasmania from 2014-2016 occurred in non-Australian born individuals. Two possible TB clusters were identified based on single locus variant analysis, one from November-December 2014 (n = 2), with the second from May-August 2015 (n = 4). We report here the first known isolate of multi-drug resistant (MDR) M. tuberculosis in Tasmania from 2016 for which we established its drug resistance mutations and potential overseas origin. In addition, we characterised a case of M. bovis TB in a Tasmanian-born person who presented in 2014, approximately 40 years after the last confirmed case in the state's bovids. CONCLUSIONS: TB in Tasmania is predominantly of overseas origin with genotypically-unique drug-susceptible isolates of M. tuberculosis. However, the state also exhibits features of TB that are observed in other jurisdictions, namely, the clustering of cases, and drug resistance. Early detection of TB and contact tracing, particularly of overseas-born cases, coordinated with rapid laboratory drug-susceptibility testing and molecular typing, will be essential for Tasmania to reach the World Health Organisation's TB eradication goals for low-incidence settings. PMID- 29466412 TI - Determinants of satisfaction with cosmetic outcome in breast cancer survivors: A cross-sectional study. AB - Little research has been done into cosmetic outcomes in non-Western breast cancer populations. We aimed to study the prevalence and determinants of dissatisfaction with cosmetic outcome after breast cancer surgery of Asian breast cancer survivors, and its association with patient-reported anxiety, depression, and quality of life. In a hospital-based cross-sectional study, 384 breast cancer survivors of at least 12 months after diagnosis completed questionnaires on satisfaction with cosmetic appearance, quality of life (EORTC-QLQ-C30) and anxiety and depression (HADS). Cumulative logit models were used to examine the adjusted association between dissatisfaction with cosmetic appearance and demographic and clinical characteristics. Kruskal-Wallis test was used to test for associations between dissatisfaction with cosmetic appearance and patient reported outcomes. Overall, 20% of women reported to be (very) dissatisfied with cosmetic appearance. Survivors of Chinese ethnicity were more likely dissatisfied with cosmetic appearance compared to Malay survivors (22% and 14% respectively, adjusted OR = 2.4, 95%CI: 1.4-3.9). Women with DCIS (adjusted OR = 2.2, 95%CI: 1.3-3.7) or advanced stage disease (adjusted OR = 2.2, 95%CI: 1.2-3.9) had a higher risk of being dissatisfied with their cosmetic appearance. Women treated with mastectomy were at a higher risk of dissatisfaction with cosmetic appearance (adjusted OR = 1.7, 95%CI: 1.1-2.5). Dissatisfaction with cosmetic appearance was associated with increased depression scores. In this South-East Asian population, one in five breast cancer patients were (very) dissatisfied with the cosmetic outcome of treatment. Chinese women, women with larger tumors and women treated with mastectomy were most likely to report dissatisfaction with cosmetic appearance. PMID- 29466413 TI - Impact of insulin on primary arcuate neurons culture is dependent on early postnatal nutritional status and neuronal subpopulation. AB - Nutrition plays a critical role in programming and shaping linear growth during early postnatal life through direct action on the development of the neuroendocrine somatotropic (GH/IGF-1) axis. IGF-1 is a key factor in modulating the programming of linear growth during this period. Notably, IGF-1 preferentially stimulates axonal growth of GHRH neurons in the arcuate nucleus of the hypothalamus (Arc), which is crucial for the proliferation of somatotroph progenitors in the pituitary, thus influencing later GH secretory capacity. However, other nutrition-related hormones may also be involved. Among them, insulin shares several structural and functional similarities with IGF-1, as well as downstream signaling effectors. We investigated the role of insulin in the control of Arc axonal growth using an in vitro model of arcuate explants culture and a cell-type specific approach (GHRH-eGFP mice) under both physiological conditions (normally fed pups) and those of dietary restriction (underfed pups). Our data suggest that insulin failed to directly control axonal growth of Arc neurons or influence specific IGF-1-mediated effects on GHRH neurons. Insulin may act on neuronal welfare, which appears to be dependent on neuronal sub populations and is influenced by the nutritional status of pups in which Arc neurons develop. PMID- 29466414 TI - Assessing the capability to experience a 'good death': A qualitative study to directly elicit expert views on a new supportive care measure grounded in Sen's capability approach. AB - BACKGROUND: Sen's capability approach is underspecified; one decision left to those operationalising the approach is how to identify sets of relevant and important capabilities. Sen has suggested that lists be developed for specific policy or research objectives through a process of public reasoning and discussion. Robeyns offers further guidance in support of Sen's position, suggesting that lists should be explicit, discussed and defended; methods be openly scrutinised; lists be considered both in terms of what is ideal and what is practical ('generality'); and that lists be exhaustive. Here, the principles suggested by Robeyns are operationalised to facilitate external scrutiny of a list of capabilities identified for use in the evaluation of supportive end of life care. METHODS: This work started with an existing list of seven capabilities (the ICECAP-SCM), identified as being necessary for a person to experience a good death. Semi-structured qualitative interviews were conducted with 20 experts in economics, psychology, ethics and palliative care, to facilitate external scrutiny of the developed list. Interviews were recorded, transcribed and analysed using constant comparison. RESULTS: The seven capabilities were found to encompass concepts identified as important by expert stakeholders (to be exhaustive) and the measure was considered feasible for use with patients receiving care at the end of life. CONCLUSION: The rigorous development of lists of capabilities using both initial participatory approaches with affected population groups, and subsequent assessment by experts, strengthens their democratic basis and may encourage their use in policy contexts. PMID- 29466415 TI - Revisiting policy on chronic HCV treatment under the Thai Universal Health Coverage: An economic evaluation and budget impact analysis. AB - Thailand is encountering challenges to introduce the high-cost sofosbuvir for chronic hepatitis C treatment as part of the Universal Health Care's benefit package. This study was conducted in respond to policy demand from the Thai government to assess the value for money and budget impact of introducing sofosbuvir-based regimens in the tax-based health insurance scheme. The Markov model was constructed to assess costs and benefits of the four treatment options that include: (i) current practice-peginterferon alfa (PEG) and ribavirin (RBV) for 24 weeks in genotype 3 and 48 weeks for other genotypes; (ii) Sofosbuvir plus peginterferon alfa and ribavirin (SOF+PEG-RBV) for 12 weeks; (iii) Sofosbuvir and daclatasvir (SOF+DCV) for 12 weeks; (iv) Sofosbuvir and ledipasvir (SOF+LDV) for 12 weeks for non-3 genotypes and SOF+PEG-RBV for 12 weeks for genotype 3 infection. Given that policy options (ii) and (iii) are for pan-genotypic infection, the cost of genotype testing was applied only for policy options (i) and (iv). Results reveal that all sofosbuvir-based regimens had greater quality adjusted life years (QALY) gains compared with the current treatment, therefore associated with lower lifetime costs and more favourable health outcomes. Additionally, among the three regimens of sofosbuvir, SOF+PEG-RBV for genotype 3 and SOF+LDV for non-3 genotype are the most cost-effective treatment option with the threshold of 160,000 THB per QALY gained. The results of this study had been used in policy discussion which resulted in the recent inclusion of SOF+PEG-RBV for genotype 3 and SOF+LDV for non-3 genotype in the Thailand's benefit package. PMID- 29466416 TI - Elevated visual dependency in young adults after chemotherapy in childhood. AB - Chemotherapy in childhood can result in long-term neurophysiological side effects, which could extend to visual processing, specifically the degree to which a person relies on vision to determine vertical and horizontal (visual dependency). We investigated whether adults treated with chemotherapy in childhood experience elevated visual dependency compared to controls and whether any difference is associated with the age at which subjects were treated. Visual dependency was measured in 23 subjects (mean age 25.3 years) treated in childhood with chemotherapy (CTS) for malignant, solid, non-CNS tumors. We also stratified CTS into two groups: those treated before 12 years of age and those treated from 12 years of age and older. Results were compared to 25 healthy, age-matched controls. The subjective visual horizontal (SVH) and vertical (SVV) orientations was recorded by having subjects position an illuminated rod to their perceived horizontal and vertical with and without a surrounding frame tilted clockwise and counter-clockwise 20 degrees from vertical. There was no significant difference in rod accuracy between any CTS groups and controls without a frame. However, when assessing visual dependency using a frame, CTS in general (p = 0.006) and especially CTS treated before 12 years of age (p = 0.001) tilted the rod significantly further in the direction of the frame compared to controls. Our findings suggest that chemotherapy treatment before 12 years of age is associated with elevated visual dependency compared to controls, implying a visual bias during spatial activities. Clinicians should be aware of symptoms such as visual vertigo in adults treated with chemotherapy in childhood. PMID- 29466417 TI - Epinephrine modulates Na+/K+ ATPase activity in Caco-2 cells via Src, p38MAPK, ERK and PGE2. AB - Epinephrine, a key stress hormone, is known to affect ion transport in the colon. Stress has been associated with alterations in colonic functions leading to changes in water movements manifested as diarrhea or constipation. Colonic water movement is driven by the Na+-gradient created by the Na+/K+-ATPase. Whether epinephrine acts via an effect on the Na+/K+-ATPase hasn't been studied before. The aim of this work was to investigate the effect of epinephrine on the Na+/K+ ATPase and to elucidate the signaling pathway involved using CaCo-2 cells as a model. The activity of the Na+/K+-ATPase was assayed by measuring the amount of inorganic phosphate released in presence and absence of ouabain, a specific inhibitor of the enzyme. Epinephrine, added for 20 minutes, decreased the activity of the Na+/K+-ATPase by around 50%. This effect was found to be mediated by alpha2 adrenergic receptors as it was fully abolished in the presence of yohimbine an alpha2-blocker, but persisted in presence of other adrenergic antagonists. Furthermore, treatment with Rp-cAMP, a PKA inhibitor, mimicked epinephrine's negative effect and didn't result in any additional inhibition when both were added simultaneously. Treatment with indomethacin, PP2, SB202190, and PD98059, respective inhibitors of COX enzymes, Src, p38MAPK, and ERK completely abrogated the effect of epinephrine. The effect of epinephrine did not appear also in presence of inhibitors of all four different types of PGE2 receptors. Western blot analysis revealed an epinephrine-induced increase in the phosphorylation of p38 MAPK and ERK that disappeared in presence of respectively PP2 and SB2020190. In addition, an inhibitory effect, similar to that of epinephrine's, was observed upon incubation with PGE2. It was concluded that epinephrine inhibits the Na+/K+-ATPase by the sequential activation of alpha2 adrenergic receptors, Src, p38MAPK, and ERK leading to PGE2 release. PMID- 29466418 TI - Evaluation of the biocontrol efficacy of a Serratia marcescens strain indigenous to tea rhizosphere for the management of root rot disease in tea. AB - The aim of the present study is to evaluate plant growth promoting and biocontrol efficacy of a Serratia marcescens strain ETR17 isolated from tea rhizosphere for the effective management of root rot disease in tea. Isolated bacterial culture ETR17 showed significant level of in vitro antagonism against nine different foliar and root pathogens of tea. The phenotypic and molecular characterization of ETR17 revealed the identity of the bacterium as Serratia marcescens. The bacterium was found to produce several hydrolytic enzymes like chitinase, protease, lipase, cellulase and plant growth promoting metabolites like IAA and siderophore. Scanning electron microscopic studies on the interaction zone between pathogen and antagonistic bacterial isolate revealed severe deformities in the fungal mycelia. Spectral analyses (LC-ESI-MS, UV-VIS spectrophotometry and HPLC) and TLC indicated the presence of the antibiotics pyrrolnitrin and prodigiosin in the extracellular bacterial culture extracts. Biofilm formation by ETR17 on polystyrene surface was also observed. In vivo application of talc-based formulations prepared with the isolate ETR17 in tea plantlets under green house conditions revealed effective reduction of root-rot disease as well as plant growth promotion to a considerable extent. Viability studies with the ETR17 talc formulation showed the survivability of the isolate up to six months at room temperature. The sustenance of ETR17 (concentration of 8-9x108 cfu g-1) in the soil after the application of talc formulation was recorded by ELISA. Safety studies revealed that ETR17 did not produce hemolysin as observed in pathogenic Serratia strains.

Lam. and I. triloba L. AB - Previously, we obtained the sweetpotato somatic hybrid KT1 from a cross between sweetpotato (Ipomoea batatas (L.) Lam.) cv. Kokei No. 14 and its drought-tolerant wild relative I. triloba L. KT1 not only inherited the thick storage root characteristic of Kokei No. 14 but also the drought-tolerance trait of I. triloba L. The aim of this study was to explore the molecular mechanism of the drought tolerance of KT1. Four-week-old in vitro-grown plants of KT1, Kokei No. 14, and I. triloba L. were subjected to a simulated drought stress treatment (30% PEG6000) for 0, 6, 12 and 24 h. Total RNA was extracted from samples at each time point, and then used for transcriptome sequencing. The gene transcript profiles of KT1 and its parents were compared to identify differentially expressed genes, and drought-related modules were screened by a weighted gene co-expression network analysis. The functions of ABI-like protein and Ca2+-ATPase, two proteins screened from the cyan and light yellow modules, were analyzed in terms of their potential roles in drought tolerance in KT1 and its parents. These analyses of the drought responses of KT1 and its somatic donors at the transcriptional level provide new annotations for the molecular mechanism of drought tolerance in the somatic hybrid KT1 and its parents.

AB - Optimism bias and positive attention bias have important highly similar implications for mental health but have only been examined in isolation. Investigating the causal relationships between these biases can improve the understanding of their underlying cognitive mechanisms, leading to new directions in neurocognitive research and revealing important information about normal functioning as well as the development, maintenance, and treatment of psychological diseases. In the current project, we hypothesized that optimistic expectancies can exert causal influences on attention deployment. To test this causal relation, we conducted two experiments in which we manipulated optimistic and pessimistic expectancies regarding future rewards and punishments. In a subsequent visual search task, we examined participants' attention to positive (i.e., rewarding) and negative (i.e., punishing) target stimuli, measuring their eye gaze behavior and reaction times. In both experiments, participants' attention was guided toward reward compared with punishment when optimistic expectancies were induced. Additionally, in Experiment 2, participants' attention was guided toward punishment compared with reward when pessimistic expectancies were induced. However, the effect of optimistic (rather than pessimistic) expectancies on attention deployment was stronger. A key characteristic of optimism bias is that people selectively update expectancies in an optimistic direction, not in a pessimistic direction, when receiving feedback. As revealed in our studies, selective attention to rewarding versus punishing evidence when people are optimistic might explain this updating asymmetry. Thus, the current data can help clarify why optimistic expectancies are difficult to overcome. Our findings elucidate the cognitive mechanisms underlying optimism and attention bias, which can yield a better understanding of their benefits for mental health.

AB - INTRODUCTION: In mental healthcare, one area of major concern identified by health information systems is variability in antipsychotic prescribing. While most studies have investigated patient- and prescriber-related factors as possible reasons for such variability, no studies have investigated facility level characteristics. The present study ascertained whether staffing level is associated with antipsychotic prescribing in community mental healthcare. METHODS: A cross-sectional analysis of data extracted from the Italian national mental health information system was carried out. For each Italian region, it collects data on the availability and use of mental health facilities. The rate of individuals exposed to antipsychotic drugs was tested for evidence of association with the rate of mental health staff availability by means of univariate and multivariate analyses. RESULTS: In Italy there were on average nearly 60 mental health professionals per 100,000 inhabitants, with wide regional variations (range 21 to 100). The average rate of individuals prescribed antipsychotic drugs was 2.33%, with wide regional variations (1.04% to 4.01%). Univariate analysis showed that the rate of individuals prescribed antipsychotic drugs was inversely associated with the rate of mental health professionals available in Italian regions (Kendall's tau -0.438, p = 0.006), with lower rates of antipsychotic prescriptions in regions with higher rates of mental health professionals. After adjustment for possible confounders, the total availability of mental health professionals was still inversely associated with the rate of individuals exposed to antipsychotic drugs. DISCUSSION: The evidence that staffing level was inversely associated with antipsychotic prescribing indicates that any actions aimed at decreasing variability in antipsychotic prescribing need to take into account aspects related to the organization of the mental health system.

AB - Rotavirus (RV), belonging to Reoviridae family, is the leading cause of acute severe viral diarrhea in children (under 5 years old) and infant animals worldwide. Although vaccines are commonly used to prevent infection, episodes of diarrhea caused by RV frequently occur. Thus, this study was conducted to determine whether resveratrol had protective effects against RV infection in piglets. Following pretreatment with resveratrol dry suspension through adding into the basal diet for 3 weeks, the piglets were orally challenged with RV. We found that resveratrol could alleviate diarrhea induced by RV infection. Resveratrol-treatment inhibited the TNF-alpha production, indicating that the anti-RV activity of resveratrol may be achieved by reducing the inflammatory response. The IFN-gamma level was elevated in 10mg/kg/d resveratrol-treated group and 30mg/kg/d resveratrol-treated group after RV infection. The ratios of CD4+/CD8+ in resveratrol-treated groups were the same as that in mock infected group, suggesting that resveratrol could maintain the immune function in RV infected piglets. It was found that resveratrol could alleviate diarrhea induced by RV infection. These results revealed that resveratrol dry suspension could be a new control measure for RV infection.

AB - Differences in regional protein expression within the human retina may explain molecular predisposition of specific regions to ophthalmic diseases like age related macular degeneration, cystoid macular edema, retinitis pigmentosa, and diabetic retinopathy. To quantify protein levels in the human retina and identify patterns of differentially-expressed proteins, we collected foveomacular, juxta macular, and peripheral retina punch biopsies from healthy donor eyes and analyzed protein content by liquid chromatography-tandem mass spectrometry (LC MS/MS). Protein expression was analyzed with 1-way ANOVA, gene ontology, pathway representation, and network analysis. We identified a mean of 1,974 proteins in the foveomacular retina, 1,999 in the juxta-macular retina, and 1,779 in the peripheral retina. Six hundred ninety-seven differentially-expressed proteins included those unique to and abundant in each anatomic region. Proteins with higher expression in each region include: heat-shock protein 90-alpha (HSP90AA1), and pyruvate kinase (PKM) in the foveomacular retina; vimentin (VIM) and fructose bisphosphate aldolase C (ALDOC); and guanine nucleotide-binding protein subunit beta-1 (GNB1) and guanine nucleotide-binding protein subunit alpha-1 (GNAT1) in the peripheral retina. Pathway analysis identified downstream mediators of the integrin signaling pathway to be highly represented in the foveomacular region (P = 6.48 e-06). Metabolic pathways were differentially expressed among all retinal regions. Gene ontology analysis showed that proteins related to antioxidant activity were higher in the juxta-macular and the peripheral retina, but present in lower amounts in the foveomacular retina. Our proteomic analysis suggests that certain retinal regions are susceptible to different forms of metabolic and oxidative stress. The findings give mechanistic insight into retina function, reveal important molecular processes, and prioritize new pathways for therapeutic targeting.

AB - Human immunodeficiency virus (HIV) causes impairment to the human immune system which leads to immunocompromised conditions, including ocular complications. Several important HIV-associated disorders may involve the anterior segment, ocular surface, and adnexae organ such as dry eye, blepharitis which reduce quality of life of patients. In present, potent antiretroviral therapies HAART (highly active antiretroviral therapy) has improved the length and quality of life which may lead to an increased prevalence of anterior segment ocular disorders. Hence, this study has been undertaken to identify the prevalence and associated factors of anterior segment and external ocular disorder in HIV infected patients in the era of HAART. A prospective descriptive cross sectional study was carried out in HIV positive patients conducted at the Department of Ophthalmology, Chiang Mai University Hospital, from February 2014 to October 2015. Detail history and ocular examination was carried out to examine for anterior segment and external ocular disorders. A total number of 363 patients were included for this prospective cross-sectional study. From the total of 363 patients, 123 patients had an anterior segment and external ocular disorder which account as the prevalence of 33.9%. The most common anterior segment manifestations was dry eye seen in 36 patients (9.9%), followed by posterior blepharitis (Meibomian gland dysfunction) seen in 23 patients (6.3%) and anterior blepharitis seen in 12 patients (3.3%). Other ocular complications included microvasculopathy, immune recovery uveitis, conjunctivitis, papilloma, anterior uveitis, corneal ulcer, nevus, trichiasis, molluscum contangiosum, Kaposi sarcoma, interstitial keratitis, conjunctival lymphangiectasia, dacryocystitis, vernal keratoconjunctivitis and eyelid penicilosis. In this study, the prevalance of anterior segment disorders was higher than in the preHAART era. Dry eye, blepharitis and uveitis were the top three most common anterior segment disorders in the HAART era. The statistical analysis showed no association between age, sex, CD4 count, duration of infection or receiving HAART and anterior segment disorders. Anterior segment abnormalities reduce the quality of life of patients, so ophthalmologists have to be aware and complete ocular examination should be performed in all HIV infected patients. PMID- 29466425 TI - Institutional transparency improves public perception of lab animal technicians and support for animal research. AB - The use of animals in research is controversial and often takes place under a veil of secrecy. Lab animal technicians responsible for the care of animals at research institutions are sometimes described as performing 'dirty work' (i.e. professions that are viewed as morally tainted), and may be stigmatized by negative perceptions of their job. This study assessed if transparency affects public perceptions of lab animal technicians and support for animal research. Participants (n = 550) were randomly assigned to one of six scenarios (using a 3x2 design) that described identical research varying only the transparency of the facility (low, high) and the species used (mice, dogs, cows). Participants provided Likert-type and open-ended responses to questions about the personal characteristics (warmth, competence) of a hypothetical lab technician 'Cathy' and their support for the described research. Quantitative analysis showed participants in the low-transparency condition perceived Cathy to be less warm and were less supportive of the research regardless of animal species. Qualitative responses varied greatly, with some participants expressing support for both Cathy and the research. These results suggest that increasing transparency in lab animal institutions could result in a more positive perception of lab animal researchers and the work that they do. PMID- 29466426 TI - Archaeological and anthropological studies on the Harappan cemetery of Rakhigarhi, India. AB - An insufficient number of archaeological surveys has been carried out to date on Harappan Civilization cemeteries. One case in point is the necropolis at Rakhigarhi site (Haryana, India), one of the largest cities of the Harappan Civilization, where most burials within the cemetery remained uninvestigated. Over the course of the past three seasons (2013 to 2016), we therefore conducted excavations in an attempt to remedy this data shortfall. In brief, we found different kinds of graves co-existing within the Rakhigarhi cemetery in varying proportions. Primary interment was most common, followed by the use of secondary, symbolic, and unused (empty) graves. Within the first category, the atypical burials appear to have been elaborately prepared. Prone-positioned internments also attracted our attention. Since those individuals are not likely to have been social deviants, it is necessary to reconsider our pre-conceptions about such prone-position burials in archaeology, at least in the context of the Harappan Civilization. The data presented in this report, albeit insufficient to provide a complete understanding of Harappan Civilization cemeteries, nevertheless does present new and significant information on the mortuary practices and anthropological features at that time. Indeed, the range of different kinds of burials at the Rakhigarhi cemetery do appear indicative of the differences in mortuary rituals seen within Harappan societies, therefore providing a vivid glimpse of how these people respected their dead. PMID- 29466427 TI - Endothelial mineralocorticoid receptor ablation does not alter blood pressure, kidney function or renal vessel contractility. AB - Aldosterone blockade confers substantial cardiovascular and renal protection. The effects of aldosterone on mineralocorticoid receptors (MR) expressed in endothelial cells (EC) within the renal vasculature have not been delineated. We hypothesized that lack of MR in EC may be protective in renal vasculature and examined this by ablating the Nr3c2 gene in endothelial cells (EC-MR) in mice. Blood pressure, heart rate and PAH clearance were measured using indwelling catheters in conscious mice. The role of the MR in EC on contraction and relaxation was investigated in the renal artery and in perfused afferent arterioles. Urinary sodium excretion was determined by use of metabolic cages. EC MR transgenics had markedly decreased MR expression in isolated aortic endothelial cells as compared to littermates (WT). Blood pressure and effective renal plasma flow at baseline and following AngII infusion was similar between groups. No differences in contraction and relaxation were observed between WT and EC-MR KO in isolated renal arteries during baseline or following 2 or 4 weeks of AngII infusion. The constriction or dilatations of afferent arterioles between genotypes were not different. No changes were found between the groups with respect to urinary excretion of sodium after 4 weeks of AngII infusion, or in urinary albumin excretion and kidney morphology. In conclusion, deletion of the EC-MR does not confer protection towards the development of hypertension, endothelial dysfunction of renal arteries or renal function following prolonged AngII-infusion. PMID- 29466428 TI - Hemagglutinin-specific neutralization of subacute sclerosing panencephalitis viruses. AB - Subacute sclerosing panencephalitis (SSPE) is a progressive, lethal complication of measles caused by particular mutants of measles virus (MeV) that persist in the brain despite high levels of neutralizing antibodies. We addressed the hypothesis that antigenic drift is involved in the pathogenetic mechanism of SSPE by analyzing antigenic alterations in the MeV envelope hemagglutinin protein (MeV H) found in patients with SSPE in relation to major circulating MeV genotypes. To this aim, we obtained cDNA for the MeV-H gene from tissue taken at brain autopsy from 3 deceased persons with SSPE who had short (3-4 months, SMa79), average (3.5 years, SMa84), and long (18 years, SMa94) disease courses. Recombinant MeVs with a substituted MeV-H gene were generated by a reverse genetic system. Virus neutralization assays with a panel of anti-MeV-H murine monoclonal antibodies (mAbs) or vaccine-immunized mouse anti-MeV-H polyclonal sera were performed to determine the antigenic relatedness. Functional and receptor-binding analysis of the SSPE MeV-H showed activity in a SLAM/nectin-4-dependent manner. Similar to our panel of wild-type viruses, our SSPE viruses showed an altered antigenic profile. Genotypes A, G3, and F (SSPE case SMa79) were the exception, with an intact antigenic structure. Genotypes D7 and F (SSPE SMa79) showed enhanced neutralization by mAbs targeting antigenic site IIa. Genotypes H1 and the recently reported D4.2 were the most antigenically altered genotypes. Epitope mapping of neutralizing mAbs BH015 and BH130 reveal a new antigenic site on MeV H, which we designated Phi for its intermediate position between previously defined antigenic sites Ia and Ib. We conclude that SSPE-causing viruses show similar antigenic properties to currently circulating MeV genotypes. The absence of a direct correlation between antigenic changes and predisposition of a certain genotype to cause SSPE does not lend support to the proposed antigenic drift as a pathogenetic mechanism in SSPE. PMID- 29466429 TI - Population nutrikinetics of green tea extract. AB - : Green tea polyphenols may contribute to the prevention of cancer and other diseases. To learn more about the pharmacokinetics and interindividual variation of green tea polyphenols after oral intake in humans we performed a population nutrikinetic study of standardized green tea extract. 84 healthy participants took green tea extract capsules standardized to 150 mg epigallocatechin-gallate (EGCG) twice a day for 5 days. On day 5 catechin plasma concentrations were analyzed using non-compartmental and population pharmacokinetic methods. A strong between-subject variability in catechin pharmacokinetics was found with maximum plasma concentrations varying more than 6-fold. The AUCs of EGCG, EGC and ECG were 877.9 (360.8-1576.5), 35.1 (8.0-87.4), and 183.6 (55.5-364.6) h*MUg/L respectively, and the elimination half lives were 2.6 (1.8-3.8), 3.9 (0.9-10.7) and 1.8 (0.8-2.9) h, respectively. Genetic polymorphisms in genes of the drug transporters MRP2 and OATP1B1 could at least partly explain the high variability in pharmacokinetic parameters. The observed variability in catechin plasma levels might contribute to interindividual variation in benefical and adverse effects of green tea polyphenols. Our data could help to gain a better understanding of the causes of variability of green tea effects and to improve the design of studies on the effects of green tea polyphenols in different health conditions. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01360320. PMID- 29466430 TI - Cholinergic signaling mediates the effects of xenin-25 on secretion of pancreatic polypeptide but not insulin or glucagon in humans with impaired glucose tolerance. AB - We previously demonstrated that infusion of an intestinal peptide called xenin-25 (Xen) amplifies the effects of glucose-dependent insulinotropic polypeptide (GIP) on insulin secretion rates (ISRs) and plasma glucagon levels in humans. However, these effects of Xen, but not GIP, were blunted in humans with type 2 diabetes. Thus, Xen rather than GIP signaling to islets fails early during development of type 2 diabetes. The current crossover study determines if cholinergic signaling relays the effects of Xen on insulin and glucagon release in humans as in mice. Fasted subjects with impaired glucose tolerance were studied. On eight separate occasions, each person underwent a single graded glucose infusion- two each with infusion of albumin, Xen, GIP, and GIP plus Xen. Each infusate was administered +/- atropine. Heart rate and plasma glucose, insulin, C-peptide, glucagon, and pancreatic polypeptide (PP) levels were measured. ISRs were calculated from C peptide levels. All peptides profoundly increased PP responses. From 0 to 40 min, peptide(s) infusions had little effect on plasma glucose concentrations. However, GIP, but not Xen, rapidly and transiently increased ISRs and glucagon levels. Both responses were further amplified when Xen was co-administered with GIP. From 40 to 240 min, glucose levels and ISRs continually increased while glucagon concentrations declined, regardless of infusate. Atropine increased resting heart rate and blocked all PP responses but did not affect ISRs or plasma glucagon levels during any of the peptide infusions. Thus, cholinergic signaling mediates the effects of Xen on insulin and glucagon release in mice but not humans. PMID- 29466432 TI - The role of pre-existing comorbidity on the rate of recovery following injury: A longitudinal cohort study. AB - Understanding the role of comorbidity in recovery following injury is an important challenge given the increasing prevalence of multimorbidity (2 or more comorbidities) in many countries. The Prospective Outcomes of Injury Study recruited 2856 injured 18-64 year olds that had registered for entitlements with New Zealand's universal no-fault injury insurer. Recovery, or lack of, in this longitudinal cohort was measured using the World Health Organization Disability Assessment Schedule at 3, 12 and 24 months post-injury. Twenty-one pre-existing chronic conditions were used to identify comorbidity. To investigate whether rates of recovery differed by pre-injury comorbidity, the interaction between time and comorbidity was modelled using Generalised Estimating Equations. Of 1,862 participants with complete data, the distribution reporting none, one comorbidity, or multimorbidity pre-injury was 51%, 27%, and 21% respectively. Longitudinal analysis estimated no difference (log odds per year 0.05, 95% Confidence Interval -0.17 to 0.27) between the rate of change of disability for those with one pre-injury comorbidity compared to those with none. Those with pre injury multimorbidity had significantly slower reduction in disability over time than those with no pre-injury comorbidity (log odds per year 0.27, 95% Confidence Interval 0.05 to 0.48). In a working age cohort, the rate of recovery in the 24 months following injury was similar for those with none or one pre-existing comorbidity and significantly slower for those with multimorbidity. It is important that further research explores mechanisms driving this, and that researchers and health providers identify and implement better supports for injured people with multimorbidity.

AB - This paper presents a novel optimization technique for energy management studies of an isolated microgrid. The system is supplied by various Distributed Energy Resources (DERs), Diesel Generator (DG), a Wind Turbine Generator (WTG), Photovoltaic (PV) arrays and supported by fuel cell/electrolyzer Hydrogen storage system for short term storage. Multi-objective optimization is used through non dominated sorting genetic algorithm to suit the load requirements under the given constraints. A novel multi-objective flower pollination algorithm is utilized to check the results. The Pros and cons of the two optimization techniques are compared and evaluated. An isolated microgrid is modelled using MATLAB software package, dispatch of active/reactive power, optimal load flow analysis with slack bus selection are carried out to be able to minimize fuel cost and line losses under realistic constraints. The performance of the system is studied and analyzed during both summer and winter conditions and three case studies are presented for each condition. The modified IEEE 15 bus system is used to validate the proposed algorithm.

AB - The taxonomy of the mottled rabbitfish Siganus fuscescens species complex has long been challenging. In this study, we analyzed microsatellite genotypes, mitochondrial lineages, and morphometric data from 373 S. fuscescens individuals sampled from the northern Philippines and Hong Kong (South China Sea, Philippine Sea and Sulu Sea basins), to examine putative species boundaries in samples comprising three co-occurring mitochondrial lineages previously reported to characterize S. fuscescens (Clade A and Clade B) or S. canaliculatus (Clade C). We report the existence of two cryptic species within S. fuscescens in the northeast region of the South China Sea and northern Philippine Sea, supported by genetic and morphological differences. Individual-based assignment methods recovered concordant groupings of individuals into two nuclear genotype clusters (Cluster 1, Cluster 2) with (1) limited gene flow, if any, between them (FST = 0.241; P < 0.001); (2) low frequency of later-generation hybrids; (3) significant association with mitochondrial Clade A and Clade B, respectively; and (4) subtle yet significant body shape differences as inferred from geometric morphometric analysis. The divergence between mitochondrial Clade C and the two other clades was not matched by genetic differences at microsatellite marker loci. The occurrence of discordant mitonuclear combinations (20.5% of the total number of individuals) is thought to result from mitochondrial introgression, consistent with a scenario of demographic, and presumably spatial, post-Pleistocene expansion of populations from northern regions into a secondary contact zone in the South China Sea. Mitonuclear discordance due to introgression obscures phylogenetic relationships for recently-diverged lineages, and cautions against the use of mitochondrial markers alone for species identification within the mottled rabbitfish species complex in the South China Sea region.

AB - OBJECTIVE: To evaluate the perinatal effects of a prenatal therapy based on intra amniotic nutritional supplementation in a rabbit model of intrauterine growth restriction (IUGR). METHODS: IUGR was surgically induced in pregnant rabbits at gestational day 25 by ligating 40-50% of uteroplacental vessels of each gestational sac. At the same time, modified-parenteral nutrition solution (containing glucose, amino acids and electrolytes) was injected into the amniotic sac of nearly half of the IUGR fetuses (IUGR-T group n = 106), whereas sham injections were performed in the rest of fetuses (IUGR group n = 118). A control group without IUGR induction but sham injection was also included (n = 115). Five days after the ligation procedure, a cesarean section was performed to evaluate fetal cardiac function, survival and birth weight. RESULTS: Survival was significantly improved in the IUGR fetuses that were treated with intra-amniotic nutritional supplementation as compared to non-treated IUGR animals (survival rate: controls 71% vs. IUGR 44% p = 0.003 and IUGR-T 63% vs. IUGR 44% p = 0.02), whereas, birth weight (controls mean 43g +/- SD 9 vs. IUGR 36g +/- SD 9 vs. IUGR T 35g +/- SD 8, p = 0.001) and fetal cardiac function were similar among the IUGR groups. CONCLUSION: Intra-amniotic injection of a modified-parenteral nutrient solution appears to be a promising therapy for reducing mortality among IUGR. These results provide an opportunity to develop new intra-amniotic nutritional strategies to reach the fetus by bypassing the placental insufficiency. PMID- 29466435 TI - Separate analysis of human papillomavirus E6 and E7 messenger RNAs to predict cervical neoplasia progression. AB - A few studies previously suggested that human papillomavirus (HPV) E6 messenger RNA (mRNA) may exist uniformly in all grades of cervical intraepithelial neoplasia (CIN), whereas the detection rate of E7 mRNA may increase with disease progression from low-grade CIN to invasive carcinoma. The aim of this study was to clarify the different roles of E6 and E7 mRNAs in cervical carcinogenesis. The presence of each E6 and E7 mRNA was analyzed in 171 patients with pathologically diagnosed CIN or cervical carcinoma. We utilized a RT-PCR assay based on consensus primers which could detect E6 mRNA (full-length E6/E7 transcript) and E7 mRNAs (spliced E6*/E7 transcripts) separately for various HPV types. E7 mRNAs were detected in 6% of CIN1, 12% of CIN2, 24% of CIN3, and 54% of cervical carcinoma. The presence of E7 mRNAs was significantly associated with progression from low-grade CIN to invasive carcinoma in contrast with E6 mRNA or high-risk HPV (HR-HPV) DNA (p = 0.00011, 0.80 and 0.54). The presence of both E6 and E7 mRNAs was significantly associated with HPV16/18 DNA but not with HR-HPV DNA (p = 0.0079 and 0.21), while the presence of E6 mRNA was significantly associated with HR-HPV DNA but not with HPV16/18 DNA (p = 0.036 and 0.089). The presence of both E6 and E7 mRNAs showed high specificity and low sensitivity (100% and 19%) for detecting CIN2+ by contrast with the positivity for HR-HPV DNA showing low specificity and high sensitivity (19% and 89%). The positive predictive value for detecting CIN2+ was even higher by the presence of both E6 and E7 mRNAs than by the positivity for HR-HPV DNA (100% vs. 91%). In 31 patients followed up for CIN1 2, the presence of both E6 and E7 mRNAs showed significant association with the occurrence of upgraded abnormal cytology in contrast with E6 mRNA, HR-HPV DNA, or HPV16/18 DNA (p = 0.034, 0.73, 0.53, and 0.72). Our findings support previous studies according to which E7 mRNA is more closely involved in cervical carcinogenesis than E6 mRNA. Moreover, the separate analysis of E6 and E7 mRNAs may be more useful than HR-HPV DNA test for detecting CIN2+ precisely and predicting disease progression. Further accumulation of evidence is warranted to validate our findings.

PMID- 29466436 TI - Loss of HCN2 leads to delayed gastrointestinal motility and reduced energy intake in mice. AB - Hyperpolarization-activated Cyclic Nucleotide-gated (HCN) channels are important regulators of excitability in neural, cardiac, and other pacemaking cells, which are often altered in disease. In mice, loss of HCN2 leads to cardiac dysrhythmias, persistent spike-wave discharges similar to those seen in absence epilepsy, ataxia, tremor, reduced neuropathic and inflammatory pain, antidepressant-like behavior, infertility, and severely restricted growth. While many of these phenotypes have tissue-specific mechanisms, the cause of restricted growth in HCN2 knockout animals remains unknown. Here, we characterize a novel, 3kb insertion mutation of Hcn2 in the Tremor and Reduced Lifespan 2 (TRLS/2J) mouse that leads to complete loss of HCN2 protein, and we show that this mutation causes many phenotypes similar to other mice lacking HCN2 expression. We then demonstrate that while TRLS/2J mice have low blood glucose levels and impaired growth, dysfunction in hormonal secretion from the pancreas, pituitary, and thyroid are unlikely to lead to this phenotype. Instead, we find that homozygous TRLS/2J mice have abnormal gastrointestinal function that is characterized by less food consumption and delayed gastrointestinal transit as compared to wildtype mice. In summary, a novel mutation in HCN2 likely leads to impaired GI motility, causing the severe growth restriction seen in mice with mutations that eliminate HCN2 expression.

PMID- 29466440 TI - Predictors of activities of daily living outcomes after upper limb robot-assisted therapy in subacute stroke patients. AB - BACKGROUND: Upper limb recovery is one of the main goals of post-stroke rehabilitation due to its importance for autonomy in Activities of Daily Living (ADL). Although the efficacy of upper limb Robot-assisted Therapy (RT) is well established in literature, the impact of the initial status of the patient on the effects of RT is still understudied. This paper aims to identify whether demographic, clinical and motor characteristics of stroke patients may influence the ability to independently perform ADL after RT. METHODS: A retrospective study was conducted on sixty stroke patients who conducted planar upper limb goal directed tasks with the InMotion 2.0 robot. The RT was administered 5 days/week for 4 weeks and each session lasted 45 minutes. The primary outcome measure was the Modified Barthel Index (BI), dichotomized into favourable (BI >=75) and unfavourable (BI<75) outcomes. The potential predictors were the demographic and clinical records, and the following clinical assessment scores: Modified Ashworth Scale-Shoulder (MAS-S); Modified Ashworth Scale-Elbow (MAS-E); Fugl-Meyer Assessment Upper Extremity (FMA-UE); upper limb section of the Motricity Index (MIul); total passive Range Of Motion (pROM); and Box and Block Test (BBT). RESULTS: Statistical analysis showed that the BBT, FMA-UE and MIul scores were significant predictors of a favourable outcome in ADL. The cut-off scores of the independent variables were calculated (FMA-UE = 32; MIul = 48; BBT = 3) with respect to the dichotomic BI outcome. Their robustness was assessed with the Fragility Index (FMA-UE = 2; MIul = 3; BBT = 7), showing that BBT is the most robust predictor of favourable BI outcome. Moreover, subjects with all predictors higher than the cut-off scores had higher probability to increase their independence in ADL at the end of the therapy. Demographic records, spasticity and pROM were not identified as predictors. CONCLUSION: Stroke patients with greater manual dexterity and less impairment appear to have a higher probability of achieving clinically significant ADL outcomes after upper limb RT. The obtained results can help to optimise the management of RT treatment planning. Further studies on a larger number of patients with a long-term follow up are recommended in order to evaluate other potential predictors and to validate the results.

PMID- 29466439 TI - Liver macrophage-associated inflammation correlates with SIV burden and is substantially reduced following cART. AB - Liver disease is a leading contributor to morbidity and mortality during HIV infection, despite the use of combination antiretroviral therapy (cART). The precise mechanisms of liver disease during HIV infection are poorly understood partially due to the difficulty in obtaining human liver samples as well as the presence of confounding factors (e.g. hepatitis co-infection, alcohol use). Utilizing the simian immunodeficiency virus (SIV) macaque model, a controlled study was conducted to evaluate the factors associated with liver inflammation and the impact of cART. We observed an increase in hepatic macrophages during untreated SIV infection that was associated with a number of inflammatory and fibrosis mediators (TNFalpha, CCL3, TGFbeta). Moreover, an upregulation in the macrophage chemoattractant factor CCL2 was detected in the livers of SIV-infected macaques that coincided with an increase in the number of activated CD16+ monocyte/macrophages and T cells expressing the cognate receptor CCR2. Expression of Mac387 on monocyte/macrophages further indicated that these cells recently migrated to the liver. The hepatic macrophage and T cell levels strongly correlated with liver SIV DNA levels, and were not associated with the levels of 16S bacterial DNA. Utilizing in situ hybridization, SIV-infected cells were found primarily within portal triads, and were identified as T cells. Microarray analysis identified a strong antiviral transcriptomic signature in the liver during SIV infection. In contrast, macaques treated with cART exhibited lower levels of liver macrophages and had a substantial, but not complete, reduction in their inflammatory profile. In addition, residual SIV DNA and bacteria 16S DNA were detected in the livers during cART, implicating the liver as a site on-going immune activation during antiretroviral therapy. These findings provide mechanistic insights regarding how SIV infection promotes liver inflammation through macrophage recruitment, with implications for in HIV-infected individuals. PMID- 29466442 TI - Soluble adenylyl cyclase: A novel player in cardiac hypertrophy induced by isoprenaline or pressure overload. AB - AIMS: In contrast to the membrane bound adenylyl cyclases, the soluble adenylyl cyclase (sAC) is activated by bicarbonate and divalent ions including calcium. sAC is located in the cytosol, nuclei and mitochondria of several tissues including cardiac muscle. However, its role in cardiac pathology is poorly understood. Here we investigate whether sAC is involved in hypertrophic growth using two different model systems. METHODS AND RESULTS: In isolated adult rat cardiomyocytes hypertrophy was induced by 24 h beta1-adrenoceptor stimulation using isoprenaline (ISO) and a beta2-adrenoceptor antagonist (ICI118,551). To monitor hypertrophy cell size along with RNA/DNA- and protein/DNA ratios as well as the expression level of alpha-skeletal actin were analyzed. sAC activity was suppressed either by treatment with its specific inhibitor KH7 or by knockdown. Both pharmacological inhibition and knockdown blunted hypertrophic growth and reduced expression levels of alpha-skeletal actin in ISO/ICI treated rat cardiomyocytes. To analyze the underlying cellular mechanism expression levels of phosphorylated CREB, B-Raf and Erk1/2 were examined by western blot. The results suggest the involvement of B-Raf, but not of Erk or CREB in the pro-hypertrophic action of sAC. In wild type and sAC knockout mice pressure overload was induced by transverse aortic constriction. Hemodynamics, heart weight and the expression level of the atrial natriuretic peptide were analyzed. In accordance, transverse aortic constriction failed to induce hypertrophy in sAC knockout mice. Mechanistic analysis revealed a potential role of Erk1/2 in TAC-induced hypertrophy. CONCLUSION: Soluble adenylyl cyclase might be a new pivotal player in the cardiac hypertrophic response either to long-term beta1-adrenoceptor stimulation or to pressure overload. PMID- 29466444 TI - Analysis of aluminum toxicity in Hordeum vulgare roots with an emphasis on DNA integrity and cell cycle. AB - Barley is one of the cereals that are most sensitive to aluminum (Al). Al in acid soils limits barley growth and development and, as a result, its productivity. The inhibition of root growth is a widely accepted indicator of Al stress. Al toxicity is affected by many factors including the culture medium, pH, Al concentration and the duration of the treatment. However, Al can act differently in different species and still Al toxicity in barley deserves study. Since the mechanism of Al toxicity is discussed we cytogenetically describe the effects of different doses of bioavailable Al on the barley nuclear genome-mitotic activity, cell cycle profile and DNA integrity. At the same time, we tested an established deep-water culture (DWC) hydroponics system and analyzed the effects of Al on the root system parameters using WinRHIZO software. We demonstrated the cytotoxic and genotoxic effect of Al in barley root cells. We showed that Al treatment significantly reduced the mitotic activity of the root tip cells and it also induced micronuclei and damaged nuclei. The DNA-damaging effect of Al was observed using the TUNEL test. We define the inhibitory influence of Al on DNA replication in barley. Analysis with the labelling and detection of 5-ethynyl-2' deoxyuridin (EdU) showed that the treatment with Al significantly decreased the frequency of S phase cells. We also demonstrated that Al exposure led to changes in the cell cycle profile of barley root tips. The delay of cell divisions observed as increased frequency of cells in G2/M phase after Al treatment was reported using flow cytometry. PMID- 29466443 TI - Burnout and self-reported suboptimal patient care amongst health care workers providing HIV care in Malawi. AB - BACKGROUND: The well-documented shortages of health care workers (HCWs) in sub Saharan Africa are further intensified by the increased human resource needs of expanding HIV treatment programs. Burnout is a syndrome of emotional exhaustion (EE), depersonalization (DP), and a sense of low personal accomplishment (PA). HCWs' burnout can negatively impact the delivery of health services. Our main objective was to examine the prevalence of burnout amongst HCWs in Malawi and explore its relationship to self-reported suboptimal patient care. METHODS: A cross-sectional study among HCWs providing HIV care in 89 facilities, across eight districts in Malawi was conducted. Burnout was measured using the Maslach Burnout Inventory defined as scores in the mid-high range on the EE or DP subscales. Nine questions adapted for this study assessed self-reported suboptimal patient care. Surveys were administered anonymously and included socio demographic and work-related questions. Validated questionnaires assessed depression and at-risk alcohol use. Chi-square test or two-sample t-test was used to explore associations between variables and self-reported suboptimal patient care. Bivariate analyses identified candidate variables (p < 0.2). Final regression models included variables with significant main effects. RESULTS: Of 520 HCWs, 62% met criteria for burnout. In the three dimensions of burnout, 55% reported moderate-high EE, 31% moderate-high DP, and 46% low-moderate PA. The majority (89%) reported engaging in suboptimal patient care/attitudes including making mistakes in treatment not due to lack of knowledge/experience (52%), shouting at patients (45%), and not performing diagnostic tests due to a desire to finish quickly (35%). In multivariate analysis, only burnout remained associated with self-reported suboptimal patient care (OR 3.22, [CI 2.11 to 4.90]; p<0.0001). CONCLUSION: Burnout was common among HCWs providing HIV care and was associated with self-reported suboptimal patient care practices/attitudes. Research is needed to understand factors that contribute to and protect against burnout and that inform the development of strategies to reduce burnout. PMID- 29466445 TI - The BPA-substitute bisphenol S alters the transcription of genes related to endocrine, stress response and biotransformation pathways in the aquatic midge Chironomus riparius (Diptera, Chironomidae). AB - Bisphenol S (BPS) is an industrial alternative to the endocrine disruptor bisphenol A (BPA), and can be found in many products labeled "BPA-free". Its use has grown in recent years, and presently it is considered a ubiquitous emerging pollutant. To date there is a lack of information on the effects of BPS on invertebrates, although they represent more than 95% of known species in the animal kingdom and are crucial for the structure and proper function of ecosystems. In this study, real-time RT-PCR was used to determine the early detrimental effects of BPS on the transcriptional rate of genes in the model species Chironomus riparius, specifically those related to the ecdysone pathway (EcR, ERR, E74, Vtg, cyp18a1) crucial for insect development and metamorphosis, stress and biotransformation mechanisms (hsp70, hsp40, cyp4g, GPx, GSTd3) that regulate adaptive responses and determine survival, and ribosome biogenesis (its2, rpL4, rpL13) which is essential for protein synthesis and homeostasis. While 24-hour exposure to 0.5, 5, 50, and 500 MUg/L BPS had no effect on larval survival, almost all the studied genes were upregulated following a non-monotonic dose-response curve. Genes with the greatest increases in transcriptional activity (fold change relative to control) were EcR (3.8), ERR (2), E74 (2.4), cyp18a1 (2.5), hsp70 (1.7), hsp40 (2.5), cyp4g (6.4), GPx (1.8), and GST (2.1), while others including Vtg, GAPDH, and selected ribosomal genes remained stable. We also measured the transcriptional activity of these genes 24 hours after BPS withdrawal and a general downregulation compared to controls was observed, though not significant in most cases. Our findings showed that BPS exposure altered the transcriptional profile of these genes, which may have consequences for the hormone system and several metabolic pathways. Although further research is needed to elucidate its mode of action, these results raise new concerns about the safety of BPA alternatives. PMID- 29466447 TI - Role of T1 mapping as a complementary tool to T2* for non-invasive cardiac iron overload assessment. AB - BACKGROUND: Iron overload-related heart failure is the principal cause of death in transfusion dependent patients, including those with Thalassemia Major. Linking cardiac siderosis measured by T2* to therapy improves outcomes. T1 mapping can also measure iron; preliminary data suggests it may have higher sensitivity for iron, particularly for early overload (the conventional cut-point for no iron by T2* is 20ms, but this is believed insensitive). We compared T1 mapping to T2* in cardiac iron overload. METHODS: In a prospectively large single centre study of 138 Thalassemia Major patients and 32 healthy controls, we compared T1 mapping to dark blood and bright blood T2* acquired at 1.5T. Linear regression analysis was used to assess the association of T2* and T1. A "moving window" approach was taken to understand the strength of the association at different levels of iron overload. RESULTS: The relationship between T2* (here dark blood) and T1 is described by a log-log linear regression, which can be split in three different slopes: 1) T2* low, <20ms, r2 = 0.92; 2) T2* = 20-30ms, r2 = 0.48; 3) T2*>30ms, weak relationship. All subjects with T2*<20ms had low T1; among those with T2*>20ms, 38% had low T1 with most of the subjects in the T2* range 20-30ms having a low T1. CONCLUSIONS: In established cardiac iron overload, T1 and T2* are concordant. However, in the 20-30ms T2* range, T1 mapping appears to detect iron. These data support previous suggestions that T1 detects missed iron in 1 out of 3 subjects with normal T2*, and that T1 mapping is complementary to T2*. The clinical significance of a low T1 with normal T2* should be further investigated. PMID- 29466446 TI - The cannabinoid-1 receptor is abundantly expressed in striatal striosomes and striosome-dendron bouquets of the substantia nigra. AB - Presynaptic cannabinoid-1 receptors (CB1-R) bind endogenous and exogenous cannabinoids to modulate neurotransmitter release. CB1-Rs are expressed throughout the basal ganglia, including striatum and substantia nigra, where they play a role in learning and control of motivated actions. However, the pattern of CB1-R expression across different striatal compartments, microcircuits and efferent targets, and the contribution of different CB1-R-expressing neurons to this pattern, are unclear. We use a combination of conventional techniques and novel genetic models to evaluate CB1-R expression in striosome (patch) and matrix compartments of the striatum, and in nigral targets of striatal medium spiny projection neurons (MSNs). CB1-R protein and mRNA follow a descending dorsolateral-to-ventromedial intensity gradient in the caudal striatum, with elevated expression in striosomes relative to the surrounding matrix. The lateral predominance of striosome CB1-Rs contrasts with that of the classical striosomal marker, the mu opioid receptor (MOR), which is expressed most prominently in rostromedial striosomes. The dorsolateral-to-ventromedial CB1-R gradient is similar to Drd2 dopamine receptor immunoreactivity and opposite to Substance P. This topology of CB1-R expression is maintained downstream in the globus pallidus and substantia nigra. Dense CB1-R-expressing striatonigral fibers extend dorsally within the substantia nigra pars reticulata, and colocalize with bundles of ventrally extending, striosome-targeted, dendrites of dopamine-containing neurons in the substantia nigra pars compacta (striosome-dendron bouquets). Within striatum, CB1-Rs colocalize with fluorescently labeled MSN collaterals within the striosomes. Cre recombinase-mediated deletion of CB1-Rs from cortical projection neurons or MSNs, and MSN-selective reintroduction of CB1-Rs in knockout mice, demonstrate that the principal source of CB1-Rs in dorsolateral striosomes is local MSN collaterals. These data suggest a role for CB1-Rs in caudal dorsolateral striosome collaterals and striosome-dendron bouquet projections to lateral substantia nigra, where they are anatomically poised to mediate presynaptic disinhibition of both striosomal MSNs and midbrain dopamine neurons in response to endocannabinoids and cannabinomimetics. PMID- 29466448 TI - A dystrophic Duchenne mouse model for testing human antisense oligonucleotides. AB - Duchenne muscular dystrophy (DMD) is a severe muscle-wasting disease generally caused by reading frame disrupting mutations in the DMD gene resulting in loss of functional dystrophin protein. The reading frame can be restored by antisense oligonucleotide (AON)-mediated exon skipping, allowing production of internally deleted, but partially functional dystrophin proteins as found in the less severe Becker muscular dystrophy. Due to genetic variation between species, mouse models with mutations in the murine genes are of limited use to test and further optimize human specific AONs in vivo. To address this we have generated the del52hDMD/mdx mouse. This model carries both murine and human DMD genes. However, mouse dystrophin expression is abolished due to a stop mutation in exon 23, while the expression of human dystrophin is abolished due to a deletion of exon 52. The del52hDMD/mdx model, like mdx, shows signs of muscle dystrophy on a histological level and phenotypically mild functional impairment. Local administration of human specific vivo morpholinos induces exon skipping and dystrophin restoration in these mice. Depending on the number of mismatches, occasional skipping of the murine Dmd gene, albeit at low levels, could be observed. Unlike previous models, the del52hDMD/mdx model enables the in vivo analysis of human specific AONs targeting exon 51 or exon 53 on RNA and protein level and muscle quality and function. Therefore, it will be a valuable tool for optimizing human specific AONs and genome editing approaches for DMD. PMID- 29466449 TI - Nitric oxide mediates antimicrobial peptide gene expression by activating eicosanoid signaling. AB - Nitric oxide (NO) mediates both cellular and humoral immune responses in insects. Its mediation of cellular immune responses uses eicosanoids as a downstream signal. However, the cross-talk with two immune mediators was not known in humoral immune responses. This study focuses on cross-talk between two immune mediators in inducing gene expression of anti-microbial peptides (AMPs) of a lepidopteran insect, Spodoptera exigua. Up-regulation of eight AMPs was observed in S. exigua against bacterial challenge. However, the AMP induction was suppressed by injection of an NO synthase inhibitor, L-NAME, while little expressional change was observed on injecting its enantiomer, D-NAME. The functional association between NO biosynthesis and AMP gene expression was further supported by RNA interference (RNAi) against NO synthase (SeNOS), which suppressed AMP gene expression under the immune challenge. The AMP induction was also mimicked by NO alone because injecting an NO analog, SNAP, without bacterial challenge significantly induced the AMP gene expression. Interestingly, an eicosanoid biosynthesis inhibitor, dexamethasone (DEX), suppressed the NO induction of AMP expression. The inhibitory activity of DEX was reversed by the addition of arachidonic acid, a precursor of eicosanoid biosynthesis. AMP expression of S. exigua was also controlled by the Toll/IMD signal pathway. The RNAi of Toll receptors or Relish suppressed AMP gene expression by suppressing NO levels and subsequently reducing PLA2 enzyme activity. These results suggest that eicosanoids are a downstream signal of NO mediation of AMP expression against bacterial challenge. PMID- 29466450 TI - Inclusion of live yeast and mannan-oligosaccharides in high grain-based diets for sheep: Ruminal parameters, inflammatory response and rumen morphology. AB - The objective of this study was to evaluate the effects of dietary supplementation with live yeast (Saccharomyces cerevisiae), mannan oligosaccharides and the combination of these additives on the inflammatory response, ruminal parameters and rumen morphology of sheep fed a high grain-based diet. Thirty-Two Dorper x Santa Ines crossbred lambs with an average weight of 24+/-2 kg were distributed in a completely randomized design. The animals were housed in individual stalls and fed ad libitum. Diet treatments were: Control (without additive); LY (2 g/kg DM of live yeast, Saccharomyces cerevisiae), MOS (2 g/kg DM of mannan-oligosaccharides) and LY+MOS (2 g/kg DM of LY + 2 g/kg DM of MOS). The experiment lasted 42 days. The supplementation with MOS alone and the additives combination resulted in increased ruminal pH (P<0.01), while the total concentrations of short chain fatty acids (SCFA) in the rumen were higher (P<0.05) only in the diets with LY and MOS. Ammonia (NH3) concentration in the rumen decreased (P<0.04) with the additives usage. Diets with LY, MOS and with additives combination reduced (P<0.01) the levels of lipopolysaccharides (LPS) in the plasma with values of 0.46; 0.44 and 0.04 EU/mL, respectively when compared to the control (0.93 EU/mL). MOS and LY+MOS treatments had reduced stratum corneum thickness (P<0.01) in comparison to the control treatment. The total thickness of ruminal epithelium was lower with the addition of MOS in the diet (P<0.03) than with LY additive. The incidence and severity of hepatic abscesses in animals whose diet was supplemented with LY and LY+MOS was lower (P<0.05) than in animals fed the control diet. The use of LY, MOS and LY+MOS in the high concentrate diets for sheep reduced NH3 concentrations and LPS translocation into the bloodstream. Diets containing MOS and LY+MOS enhanced the health of the ruminal epithelium by reducing the thickness of the stratum corneum, and diets containing LY and LY+MOS decreased the incidence and severity of hepatic abscesses. PMID- 29466451 TI - Implementing a novel movement-based approach to inferring parturition and neonate caribou calf survival. AB - In ungulates, parturition is correlated with a reduction in movement rate. With advances in movement-based technologies comes an opportunity to develop new techniques to assess reproduction in wild ungulates that are less invasive and reduce biases. DeMars et al. (2013, Ecology and Evolution 3:4149-4160) proposed two promising new methods (individual- and population-based; the DeMars model) that use GPS inter-fix step length of adult female caribou (Rangifer tarandus caribou) to infer parturition and neonate survival. Our objective was to apply the DeMars model to caribou populations that may violate model assumptions for retrospective analysis of parturition and calf survival. We extended the use of the DeMars model after assigning parturition and calf mortality status by examining herd-wide distributions of parturition date, calf mortality date, and survival. We used the DeMars model to estimate parturition and calf mortality events and compared them with the known parturition and calf mortality events from collared adult females (n = 19). We also used the DeMars model to estimate parturition and calf mortality events for collared female caribou with unknown parturition and calf mortality events (n = 43) and instead derived herd-wide estimates of calf survival as well as distributions of parturition and calf mortality dates and compared them to herd-wide estimates generated from calves fitted with VHF collars (n = 134). For our data, the individual-based method was effective at predicting calf mortality, but was not effective at predicting parturition. The population-based method was more effective at predicting parturition but was not effective at predicting calf mortality. At the herd level, the predicted distributions of parturition date from both methods differed from each other and from the distribution derived from the parturition dates of VHF-collared calves (log-ranked test: chi2 = 40.5, df = 2, p < 0.01). The predicted distributions of calf mortality dates from both methods were similar to the observed distribution derived from VHF-collared calves. Both methods underestimated herd-wide calf survival based on VHF-collared calves, however, a combination of the individual- and population-based methods produced herd-wide survival estimates similar to estimates generated from collared calves. The limitations we experienced when applying the DeMars model could result from the shortcomings in our data violating model assumptions. However despite the differences in our caribou systems, with proper validation techniques the framework in the DeMars model is sufficient to make inferences on parturition and calf mortality. PMID- 29466452 TI - Self-compassion moderates the perfectionism and depression link in both adolescence and adulthood. AB - BACKGROUND: Psychological practitioners often seek to directly change the form or frequency of clients' maladaptive perfectionist thoughts, because such thoughts predict future depression. Indirect strategies, such as self-compassion interventions, that seek to change clients' relationships to difficult thoughts, rather than trying to change the thoughts directly could be just as effective. This study aimed to investigate whether self-compassion moderated, or weakened, the relationship between high perfectionism and high depression symptoms in both adolescence and adulthood. METHODS: The present study utilised anonymous self report questionnaires to assess maladaptive perfectionism, depression, and self compassion across two samples covering much of the lifespan. Questionnaires were administered in a high school setting for the adolescent sample (Study 1, Mage = 14.1 years, n = 541), and advertised through university and widely online to attract a convenience sample of adults (Study 2, Mage = 25.22 years, n = 515). RESULTS: Moderation analyses revealed that self-compassion reduced the strength of relationship between maladaptive perfectionism and depression in our adolescent Study 1 (beta = -.15, p < .001, R2 = .021.) and our adult study 2 (beta = -.14, p < .001, R2 = .020). LIMITATIONS: Cross-sectional self-reported data restricts the application of causal conclusions and also relies on accurate self-awareness and willingness to respond to questionnaire openly. CONCLUSIONS: The replication of this finding in two samples and across different age appropriate measures suggests that self-compassion does moderate the link between perfectionism and depression. Self-compassion interventions may be a useful way to undermine the effects of maladaptive perfectionism, but future experimental or intervention research is needed to fully assess this important possibility. PMID- 29466453 TI - Palladium nanoparticle-decorated reduced graphene oxide sheets synthesized using Ficus carica fruit extract: A catalyst for Suzuki cross-coupling reactions. AB - We present a biogenic method for the synthesis of palladium nanoparticle (PdNP) modified by reducing graphene oxide sheets (rGO) in a one-pot strategy using Ficus carica fruit juice as the reducing agent. The synthesized material was well characterized by morphological and structural analyses, including, Ultraviolet Visible spectroscopy (UV-Vis), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and Transmission Electron Microscopy (TEM) and Raman spectroscopy. The results revealed that the PdNP modified GO are spherical in shape and estimated to be a dimension of ~0.16 nm. The PdNP/graphene exhibits a great catalytic activity in Suzuki cross-coupling reactions for the synthesis of biaryl compounds with various substrates under both aqueous and aerobic conditions. The catalyst can be recovered easily and is suitable for repeated use because it retains its original catalytic activity. The PdNP/rGO catalyst synthesized by an eco-friendly protocol was used for the Suzuki coupling reactions. The method offers a mild and effective substitute to the existing methods and may significantly contribute to green chemistry. PMID- 29466454 TI - Interaction between FKBP5 variability and recent life events in the anxiety spectrum: Evidence for the differential susceptibility model. AB - BACKGROUND: Gene-environment interaction (GxE) research has highlighted the importance of investigating the FK506 binding protein 51 (FKBP5) gene as a sensitivity gene. However, previous GxE studies with FKBP5 have not measured the full environmental spectrum or applied statistical tests to discern whether the GxE interaction fits better with the differential-susceptibility or diathesis stress hypotheses. This study examined whether single nucleotide polymorphisms (SNPs) on FKBP5 gene moderate the association of positive and negative recent life events (LEs) with depressive symptoms, state-anxiety, neuroticism, and social anxiety traits. METHODS: A total of 86 nonclinical young adults were administered psychological measures and were genotyped for five FKBP5 SNPs (rs3800373, rs9296158, rs1360780, rs9470080 and rs4713916). RESULTS: Regression analyses indicated significant GxE interactions for social anxiety and neuroticism. The interactions predicting neuroticism fit different models for different SNPs, although the overall effect indicated by the haplotype was consistent with the differential-susceptibility hypothesis: the risk-haplotype group presented higher neuroticism in the presence of more negative LEs and lower neuroticism in the presence of more positive LEs. The GxE interactions for social anxiety were consistent with the diathesis-stress model. The lack of significance in the for-better side for social anxiety might be related to the fact that it mapped onto low extraversion, which is associated with a lower permeability to positive experiences. DISCUSSION: Findings underscore the importance of testing the differential-susceptibility model in relation to FKBP5 to adequately characterize its role in healthy and pathological developmental processes. PMID- 29466455 TI - A pneumatic Bionic Voice prosthesis-Pre-clinical trials of controlling the voice onset and offset. AB - Despite emergent progress in many fields of bionics, a functional Bionic Voice prosthesis for laryngectomy patients (larynx amputees) has not yet been achieved, leading to a lifetime of vocal disability for these patients. This study introduces a novel framework of Pneumatic Bionic Voice Prostheses as an electronic adaptation of the Pneumatic Artificial Larynx (PAL) device. The PAL is a non-invasive mechanical voice source, driven exclusively by respiration with an exceptionally high voice quality, comparable to the existing gold standard of Tracheoesophageal (TE) voice prosthesis. Following PAL design closely as the reference, Pneumatic Bionic Voice Prostheses seem to have a strong potential to substitute the existing gold standard by generating a similar voice quality while remaining non-invasive and non-surgical. This paper designs the first Pneumatic Bionic Voice prosthesis and evaluates its onset and offset control against the PAL device through pre-clinical trials on one laryngectomy patient. The evaluation on a database of more than five hours of continuous/isolated speech recordings shows a close match between the onset/offset control of the Pneumatic Bionic Voice and the PAL with an accuracy of 98.45 +/-0.54%. When implemented in real-time, the Pneumatic Bionic Voice prosthesis controller has an average onset/offset delay of 10 milliseconds compared to the PAL. Hence it addresses a major disadvantage of previous electronic voice prostheses, including myoelectric Bionic Voice, in meeting the short time-frames of controlling the onset/offset of the voice in continuous speech. PMID- 29466456 TI - HMP-1/alpha-catenin promotes junctional mechanical integrity during morphogenesis. AB - Adherens junctions (AJs) are key structures regulating tissue integrity and maintaining adhesion between cells. During morphogenesis, junctional proteins cooperate closely with the actomyosin network to drive cell movement and shape changes. How the junctions integrate the mechanical forces in space and in time during an in vivo morphogenetic event is still largely unknown, due to a lack of quantitative data. To address this issue, we inserted a functional Fluorescence Resonance Energy Transfer (FRET)-based force biosensor within HMP-1/alpha-catenin of Caenorhabditis elegans. We find that the tension exerted on HMP-1 has a cell specific distribution, is actomyosin-dependent, but is regulated differently from the tension on the actin cortex during embryonic elongation. By using time-lapse analysis of mutants and tissue-specific rescue experiments, we confirm the role of VAB-9/Claudin as an actin bundle anchor. Nevertheless, the tension exerted on HMP-1 did not increase in the absence of VAB-9/Claudin, suggesting that HMP-1 activity is not upregulated to compensate for loss of VAB-9. Our data indicate that HMP-1 does not modulate HMR-1/E-cadherin turnover, is required to recruit junctional actin but not stress fiber-like actin bundles. Altogether, our data suggest that HMP-1/alpha-catenin acts to promote the mechanical integrity of adherens junctions. PMID- 29466457 TI - Far-UVC light prevents MRSA infection of superficial wounds in vivo. AB - BACKGROUND: Prevention of superficial surgical wound infections from drug resistant bacteria such as methicillin resistant Staphylococcus aureus (MRSA) currently present major health care challenges. The majority of surgical site infections (SSI) are believed to be caused by airborne transmission of bacteria alighting onto the wound during surgical procedures. We have previously shown that far-ultraviolet C light in the wavelength range of 207-222 nm is significantly harmful to bacteria, but without damaging mammalian cells and tissues. It is important that the lamp be fitted with a filter to remove light emitted at wavelengths longer than 230 nm which are harmful. AIMS: Using a hairless mouse model of infection of superficial wounds, here we tested the hypothesis that 222-nm light kills MRSA alighting onto a superficial skin incisions as efficiently as typical germicidal light (254 nm), but without inducing skin damage. METHODS: To simulate the scenario wherein incisions are infected during surgical procedures as pathogens in the room alight on a wound, MRSA was spread on a defined area of the mouse dorsal skin; the infected skin was then exposed to UVC light (222 nm or 254 nm) followed by a superficial incision within the defined area, which was immediately sutured. Two and seven days post procedure, bactericidal efficacy was measured as MRSA colony formation unit (CFU) per gram of harvested skin whereas fixed samples were used to assess skin damage measured in terms of epidermal thickness and DNA photodamage. RESULTS: In the circumstance of superficial incisions infected with bacteria alighting onto the wound, 222-nm light showed the same bactericidal properties of 254-nm light but without the associated skin damage. CONCLUSIONS: Being safe for patient and hospital staff, our results suggested that far-UVC light (222 nm) might be a convenient approach to prevent transmission of drug-resistant infectious agents in the clinical setting. PMID- 29466458 TI - Flogging tired horses: Who wants whipping and who would walk away if whipping horses were withheld? AB - Recent studies have cast doubt on the effectiveness of whipping horses during races and this has led to questions concerning its continuing justification. Furthermore, it has been argued that whipping tired horses in racing is the most televised form of violence to animals. The present study used de-identified data from a recent independent Australian poll (n = 1,533) to characterise the 26% of respondents (113 females and 271 males) who support the whipping of racehorses and the 10% of racing enthusiasts in the sample (44 females and 63 males) who would stop watching races and betting on them if whipping were banned. Logistic regression models examining associations between age, gender, and income level of respondents demonstrated that those who support racehorse whipping are significantly more likely to be male. Among racing enthusiasts who would stop watching races and betting on them if whipping were banned, those in the lowest income bracket were over-represented. The more frequently respondents attended races or gambled on them, the more likely they were to agree that horses should be hit with a whip during the normal course of a race. These findings align with previous studies of violence among men and women but may also be attributed to male support of traditional gambling practices. Globally, racing organisations may consider the findings of the present study helpful in their deliberations on the merits of continuing the practice of whipping tired horses in the name of sport. The study might also provide important data for stakeholders who demand that it continues. PMID- 29466459 TI - Global influenza seasonality to inform country-level vaccine programs: An analysis of WHO FluNet influenza surveillance data between 2011 and 2016. AB - By analyzing publicly available surveillance data from 2011-2016, we produced country-specific estimates of seasonal influenza activity for 118 countries in the six World Health Organization regions. Overall, the average country influenza activity period was 4.7 months. Our analysis characterized 100 countries (85%) with one influenza peak season, 13 (11%) with two influenza peak seasons, and five (4%) with year-round influenza activity. Surveillance data were limited for many countries. These data provide national estimates of influenza activity, which may guide planning for influenza vaccination implementation, program timing and duration, and policy development.

AB - It is generally assumed that populations of a species will have similar responses to climate change, and thereby that a single value of sensitivity will reflect species-specific responses. However, this assumption is rarely systematically tested. High intraspecific variation will have consequences for identifying species- or population-level traits that can predict differences in sensitivity, which in turn can affect the reliability of projections of future climate change impacts. We investigate avian body condition responses to changes in six climatic variables and how consistent and generalisable these responses are both across and within species, using 21 years of data from 46 common passerines across 80 Dutch sites. We show that body condition decreases with warmer spring/early summer temperatures and increases with higher humidity, but other climate variables do not show consistent trends across species. In the future, body condition is projected to decrease by 2050, mainly driven by temperature effects. Strikingly, populations of the same species generally responded just as differently as populations of different species implying that a single species signal is not meaningful. Consequently, species-level traits did not explain interspecific differences in sensitivities, rather population-level traits were more important. The absence of a clear species signal in body condition responses implies that generalisation and identifying species for conservation prioritisation is problematic, which sharply contrasts conclusions of previous studies on the climate sensitivity of phenology.

AB - Random fluctuations in temperature and precipitation have substantial impacts on agricultural output. However, the contribution of these changing configurations in weather to total factor productivity (TFP) growth has not been addressed explicitly in econometric analyses. Thus, the key objective of this study is to quantify and to investigate the role of changing weather patterns in explaining yearly fluctuations in TFP. For this purpose, we define TFP to be a measure of total output divided by a measure of total input. We estimate a stochastic production frontier model using U.S. state-level agricultural data incorporating growing season temperature and precipitation, and intra-annual standard deviations of temperature and precipitation for the period 1960-2004. We use the estimated parameters of the model to compute a TFP index that has good axiomatic properties. We then decompose TFP growth in each state into weather effects, technological progress, technical efficiency, and scale-mix efficiency changes. This approach improves our understanding of the role of different components of TFP in agricultural productivity growth. We find that annual TFP growth averaged 1.56% between 1960 and 2004. Moreover, we observe substantial heterogeneity in weather effects across states and over time.

AB - The pathogenesis of herpes zoster is closely linked to reduced varicella-zoster virus-specific cell-mediated immunity. However, little is known about the interplay between natural killer cells and psychological stress in the pathogenesis of herpes zoster. This study aimed to investigate possible associations among natural killer cells, T cells and psychological stress in herpes zoster. Interferon-gamma secretion from natural killer cell, psychological stress events, stress cognition scale scores and cytomegalovirus-specific cell mediated immunity were compared between 44 patients with herpes zoster and 44 age and gender-matched control subjects. A significantly lower median level of interferon-gamma secreted by natural killer cells was observed in patients with a recent diagnosis of herpes zoster than in control subjects (582.7 pg/ml vs. 1783 pg/ml; P = 0.004), whereas cytomegalovirus-specific cell-mediated immunity was not associated with herpes zoster. Psychological stress events and high stress cognition scale scores were significantly associated in patients with herpes zoster (P<0.001 and P = 0.037, respectively). However, reduced interferon-gamma secretion from natural killer cell and psychological stress were not associated. In conclusion, patients with a recent diagnosis of herpes zoster display reduced interferon-gamma secretion from natural killer cells and frequent previous psychological stress events compared with controls. However, reduced natural killer cell activity is not an immunological mediator between psychological stress and herpes zoster.

AB - Victim support services, in mature societies, aim to help victims recover after suffering a traumatic event. The effectiveness of victim support has traditionally been evaluated through rates of service utilization and incidence of psychopathology such as posttraumatic stress disorder. The current study, instead, inquires into service users' unmet needs and satisfaction, and identifies factors that mediate such subjective measures, using data from a national cross-sectional survey on victims and surviving families of violent crime in Taiwan in 2011. The results reveal: 1) a gap between available and expected services, and 2) a correlation between service utilization and satisfaction, both consistent with previous studies. In addition, the current study identifies unsatisfied service users: They are homicidally bereaved, live with their spouse, suffer from post-crime financial distress and are still waiting for a court verdict on the incident. Victim support that helps victims heal through tailored services incorporating relationship counseling is proposed. PMID- 29466464 TI - Factors that enable or limit the sustained use of improved firewood cookstoves: Qualitative findings eight years after an intervention in rural Mexico. AB - OBJECTIVE: The aim of this study was to analyze the factors enabling/limiting the use of improved cookstoves among rural fuel wood users from one mestizo and two indigenous communities eight years after an intervention in the state of Michoacan, in Mexico. METHODS: A qualitative study with an ethnographic perspective was conducted in 2013/2014 based on 62 interviews with women who had participated in an improved firewood cookstove program in 2005. Thematic qualitative content analysis was performed. RESULTS: Very few women from the indigenous communities were using the improved cookstove at the time of the study; the majority had dismantled or had ceased using it; whereas most of those from the mestizo community were using it for all of their cooking activities. In the indigenous communities, characterized by extended families, uptake of new technology was limited by traditional routine practices, rearrangement of rooms in the house, attachment to the traditional stove, a low- or non-risk perception of woodsmoke; gender relations, insufficient training, non-compliance with program recommendations and design-related aspects. Conversely, in the mestizo community, the uptake of the improved cookstove was favored by routine cooking practices in a nuclear family, a previous use of a raised cookstove and social representations on the health-disease-death effects of woodsmoke vs. the health benefits of cooking with improved stoves. The sociocultural dimension of communities and the cookstove design are aspects that either favor or limit the use of improved cookstoves in indigenous and mestizo populations. CONCLUSIONS: Effective cookstove programs must take these elements into account from their early planning stages, and blend them into implementation and follow-up. Project communication, training and differentiated follow-up activities ensuring the operation and maintenance of the cookstove, should be designed according to the specific needs and traditions of each community; they should be based on the preferences and needs of the users. PMID- 29466465 TI - Analysis of the genetic basis of plant height-related traits in response to ethylene by QTL mapping in maize (Zea mays L.). AB - Ethylene (ET) is critical importance in the growth, development, and stress responses of plants. Plant hormonal stress responses have been extensively studied, however, the role of ET in plant growth, especially plant height (PH) remains unclear. Understanding the genetic control for PH in response to ET will provide insights into the regulation of maize development. To clarify the genetic basis of PH-related traits of maize in response to ET, we mapped QTLs for PH, ear height (EH), and internode length above the uppermost ear (ILAU) in two recombinant inbred line (RIL) populations of Zea mays after ET treatment and in an untreated control (CK) group. Sixty QTLs for the three traits were identified. Twenty-two QTLs were simultaneously detected under both ET treatment and untreated control, and five QTLs were detected at two geographic locations under ET treatment only. Individual QTL can be explained 3.87-17.71% of the phenotypic variance. One QTL (q2PH9-1, q1PH9, q1EH9/q1ILAU9-1, q2ILAU9, and q2EH9) for the measured traits (PH, EH, ILAU) was consistent across both populations. Two QTLs (q2PH2-5, q2ILAU2-2, q1PH2-2, and q1ILAU2-2; q1PH8-1, q1EH8-1, q2PH8-1) were identified for up to two traits in both locations and populations under both ET treatment and untreated control. These consistent and stable regions are important QTLs of potential hot spots for PH, ear height (EH), and internode length above the uppermost ear (ILAU) response to ET in maize; therefore, QTL fine-mapping and putative candidate genes validation should enable the cloning of PH, EH, and ILAU related genes to ET response. These results will be valuable for further fine-mapping and quantitative trait nucleotides (QTNs) determination, and elucidate the underlying molecular mechanisms of ET responses in maize. PMID- 29466466 TI - Family history and obesity in youth, their effect on acylcarnitine/aminoacids metabolomics and non-alcoholic fatty liver disease (NAFLD). Structural equation modeling approach. AB - BACKGROUND: Structural equation modeling (SEM) can help understanding complex functional relationships among obesity, non-alcoholic fatty liver disease (NAFLD), family history of obesity, targeted metabolomics and pro-inflammatory markers. We tested two hypotheses: 1) If obesity precedes an excess of free fatty acids that increase oxidative stress and mitochondrial dysfunction, there would be an increase of serum acylcarnitines, amino acids and cytokines in obese subjects. Acylcarnitines would be related to non-alcoholic fatty disease that will induce insulin resistance. 2) If a positive family history of obesity and type 2 diabetes are the major determinants of the metabolomic profile, there would be higher concentration of amino acids and acylcarnitines in patients with this background that will induce obesity and NAFLD which in turn will induce insulin resistance. METHODS/RESULTS: 137 normoglycemic subjects, mean age (SD) of 30.61 (8.6) years divided in three groups: BMI<25 with absence of NAFLD (G1), n = 82; BMI>30 with absence of NAFLD (G2), n = 24; and BMI>30 with NAFLD (G3), n = 31. Family history of obesity (any) was present in 53%. Both models were adjusted in SEM. Family history of obesity predicted obesity but could not predict acylcarnitines and amino acid concentrations (effect size <0.2), but did predict obesity phenotype. CONCLUSION: Family history of obesity is the major predictor of obesity, and the metabolic abnormalities on amino acids, acylcarnitines, inflammation, insulin resistance, and NAFLD. PMID- 29466467 TI - Fragments of peer review: A quantitative analysis of the literature (1969-2015). AB - This paper examines research on peer review between 1969 and 2015 by looking at records indexed from the Scopus database. Although it is often argued that peer review has been poorly investigated, we found that the number of publications in this field doubled from 2005. A half of this work was indexed as research articles, a third as editorial notes and literature reviews and the rest were book chapters or letters. We identified the most prolific and influential scholars, the most cited publications and the most important journals in the field. Co-authorship network analysis showed that research on peer review is fragmented, with the largest group of co-authors including only 2.1% of the whole community. Co-citation network analysis indicated a fragmented structure also in terms of knowledge. This shows that despite its central role in research, peer review has been examined only through small-scale research projects. Our findings would suggest that there is need to encourage collaboration and knowledge sharing across different research communities. PMID- 29466468 TI - Fluorescent single-stranded DNA-binding protein from Plasmodium falciparum as a biosensor for single-stranded DNA. AB - Single-stranded DNA (ssDNA) is a product of many cellular processes that involve double-stranded DNA, for example during DNA replication and repair, and is formed transiently in many others. Measurement of ssDNA formation is fundamental for understanding many such processes. The availability of a fluorescent biosensor for the determination of single-stranded DNA provides an important route to achieve this. Single-stranded DNA binding proteins (SSBs) protect ssDNA from degradation, but can be displaced to allow processing of the ssDNA. Their tight binding of ssDNA means that they are very good candidates for the development of a biosensor. Previously, the single stranded DNA binding protein from Escherichia coli, labeled with a fluorophore, (DCC-EcSSB) was developed and used for this purpose. However, the multiple binding modes of this protein meant that interpretation of DCC-EcSSB fluorescence was potentially complex in terms of determining the amount of ssDNA. Here, we present an improved biosensor, developed using the tetrameric SSB from Plasmodium falciparum as a new scaffold for fluorophore attachment. Each subunit of this tetrameric SSB was labeled with a diethylaminocoumarin fluorophore at a single site on its surface, such that there is a very large, 20-fold, fluorescence increase when it binds to ssDNA. This adduct can be used as a biosensor to report ssDNA formation. Because SSB from this organism has a single mode of binding ssDNA, namely 65-70 bases per tetramer, over a wide range of conditions, the fluorescent SSB allows simple quantitation of ssDNA. The binding is fast, possibly diffusion controlled, and tight (dissociation constant for DCC-PfSSB <5 pM). Its suitability for real-time assays of ssDNA formation was demonstrated by measurement of AddAB helicase activity, unwinding double-stranded DNA. PMID- 29466469 TI - ERP evidence for consumer evaluation of copycat brands. AB - Copycat brands mimic brand leaders to free ride on the latter's equity. However, little is known regarding if and how consumers confuse copycat as leading brand in purchasing. In this study, we applied a word-pair evaluation paradigm in which the first word was a brand name (copycat vs. normal brand both similar with a leading brand in category), followed by a product name (near vs. far from the leading brand's category). Behavioral results showed that, when the product is near the leader's category, the copycat strategy (CN) was more preferred compared to the normal brand (NN) but not different in the far product condition (CF and NF). Event-related potential (ERP) data provided further insight into the mechanism. The N400 amplitude elicited by the CN condition was significantly smaller than NN. However, when products are far from the leader's category, there was no significant difference in N400 amplitudes. For the late positive component (LPC), the CN gave rise to a larger amplitude than the CF. The N400 amplitude was suggested to reflect the categorization process, and the LPC demonstrated the recollection process in long-term memory. These findings imply that the copycat brand strategy is generally only effective when products are within the category of the leading brand, which offers important implications for marketing practices. PMID- 29466470 TI - Early intervention for subthreshold panic disorder in the Netherlands: A model based economic evaluation from a societal perspective. AB - BACKGROUND: Panic disorder (PD) is associated with impaired functioning and reduced quality of life. In the Netherlands, almost 2% of the population experiences clinically relevant panic symptoms without meeting the diagnostic criteria for PD, which is referred to as subthreshold PD (STHPD). Evidence suggests that subthreshold mental disorders may have a similar impact on quality of life and functioning in comparison with full-blown mental disorders, which draws attention to the need for interventions for STHPD. These interventions are currently not systematically provided in clinical practice. This study aims to investigate the population cost-effectiveness of adding a CBT-based early intervention for adults with STHPD to the existing health care for people with PD in the Netherlands. METHODS: A health-economic Markov model was constructed in order to compare quality adjusted life-years (QALYs) and societal costs of adding an early intervention to usual care for PD. The model compares usual care with an alternative program in which usual care is supplemented with a CBT-based early intervention. Input parameters for the model were derived from national sources and published literature where possible, and based on expert opinion otherwise. Probabilistic and deterministic sensitivity analyses were conducted to evaluate the uncertainty of the model input parameters. RESULTS: On average, the added CBT based early intervention was dominant in comparison with usual care, meaning that the early intervention yielded more QALYs at lower costs. At a willingness-to-pay threshold of ?20,000 per QALY, the cost-effectiveness probability of the added early intervention was 98%. Sensitivity analyses showed that the results were robust. CONCLUSIONS: This study showed that offering an early intervention in addition to usual care for PD is potentially cost-effective, but it should be further investigated to what extent trial results can be extrapolated to the level of the population before such interventions are implemented on a large scale.

PMID- 29466472 TI - When listening to rain sounds boosts arithmetic ability. AB - Studies in the literature have provided conflicting evidence about the effects of background noise or music on concurrent cognitive tasks. Some studies have shown a detrimental effect, while others have shown a beneficial effect of background auditory stimuli. The aim of this study was to investigate the influence of agitating, happy or touching music, as opposed to environmental sounds or silence, on the ability of non-musician subjects to perform arithmetic operations. Fifty university students (25 women and 25 men, 25 introverts and 25 extroverts) volunteered for the study. The participants were administered 180 easy or difficult arithmetic operations (division, multiplication, subtraction and addition) while listening to heavy rain sounds, silence or classical music. Silence was detrimental when participants were faced with difficult arithmetic operations, as it was associated with significantly worse accuracy and slower RTs than music or rain sound conditions. This finding suggests that the benefit of background stimulation was not music-specific but possibly due to an enhanced cerebral alertness level induced by the auditory stimulation. Introverts were always faster than extroverts in solving mathematical problems, except when the latter performed calculations accompanied by the sound of heavy rain, a condition that made them as fast as introverts. While the background auditory stimuli had no effect on the arithmetic ability of either group in the easy condition, it strongly affected extroverts in the difficult condition, with RTs being faster during agitating or joyful music as well as rain sounds, compared to the silent condition. For introverts, agitating music was associated with faster response times than the silent condition. This group difference may be explained on the basis of the notion that introverts have a generally higher arousal level compared to extroverts and would therefore benefit less from the background auditory stimuli. PMID- 29466473 TI - Combined epidural-general anesthesia was associated with lower risk of postoperative complications in patients undergoing open abdominal surgery for pheochromocytoma: A retrospective cohort study. AB - BACKGROUND: Current evidences show that regional anesthesia is associated with decreased risk of complications after major surgery. However, the effects of combined regional-general anesthesia remain controversial. The purpose of our study was to analyze the impact of anesthesia (combined epidural-general anesthesia vs. general anesthesia) on the risk of postoperative complications in patients undergoing open surgery for pheochromocytoma. METHODS: This was a retrospective cohort study. 146 patients who underwent open surgery for pheochromocytoma (100 received combined epidural-general anesthesia and 46 received general anesthesia) in Peking University First Hospital from January 1, 2002 to December 31, 2015 were enrolled. The primary outcome was the occurrence of postoperative complications during hospital stay after surgery. Multivariate Logistic regression models were used to analyze the association between the choice of anesthetic method and the risk of postoperative complications. RESULTS: 17 (11.6%) patients developed complications during postoperative hospital stay. The incidence of postoperative complications was lower in patients with combined epidural-general anesthesia than in those with general anesthesia (6% [6/100] vs. 23.9% [11/46], P = 0.006). Multivariate Logistic regression analysis showed that use of combined epidural-general anesthesia (OR 0.219, 95% CI 0.065-0.741; P = 0.015) was associated with lower risk, whereas male gender (OR 5.213, 95% CI 1.283-21.177; P = 0.021) and perioperative blood transfusion (OR 25.879; 95% CI 3.130-213.961; P = 0.003) were associated with higher risk of postoperative complications. CONCLUSIONS: For patients undergoing open surgery for pheochromocytoma, use of combined epidural-general anesthesia may decrease the occurrence of postoperative complications. PMID- 29466475 TI - Cost Effectiveness of Arthrocentesis Compared to Conservative Therapy for Arthralgia of the Temporomandibular Joint: A Randomized Controlled Trial. AB - AIMS: To determine the cost effectiveness and cost utility of arthrocentesis as an initial treatment for temporomandibular joint (TMJ) arthralgia compared to usual care. METHODS: A two-armed, parallel-design, randomized controlled trial (RCT) was conducted in the Netherlands from January 2009 to June 2012 that included patients with TMJ arthralgia. Patients were randomly allocated to arthrocentesis (n = 40) or usual care (n = 40) for initial treatment. Arthrocentesis consisted of rinsing the intra-articular space with isotonic saline, and usual care included a soft diet, physical therapy, and splint therapy. The duration of the usual care program was 6 weeks, and follow-up was conducted 3, 12, and 26 weeks after its completion. Generalized estimated equation multivariate models were assessed in order to correct for the dependency of repeated measurements in the longitudinal data analysis. An independent samples t test was used to compare the arthrocentesis group with the usual care group for TMJ pain after 26 weeks. Cost effectiveness (total cost from a societal view) was related to TMJ pain (as measured on a visual analog scale [0 to 100 mm]) and to cost utility (quality-adjusted life years). RESULTS: TMJ pain declined more quickly in the arthrocentesis group (n = 36) than in the usual care group (n = 36) (regression coefficient beta = -10.76; 95% confidence interval [CI] = -17.75 to -3.77; P = .003). The estimated mean total (ie, societal) cost over 26 weeks was ?589 (US $795) in the arthrocentesis group and ?1,680 (US $2,266) in the usual care group. Arthrocentesis was associated with a lower mean cost and better health outcomes than usual care in 98% and 95% of the bootstrap simulations, respectively. CONCLUSION: The results of this study suggest that, from an economical perspective, arthrocentesis may be superior to usual care for the initial treatment of TMJ pain, as it had better health outcomes and lower costs than usual care. PMID- 29466474 TI - Early measurement of interleukin-10 predicts the absence of CT scan lesions in mild traumatic brain injury. AB - Traumatic brain injury is a common event where 70%-90% will be classified as mild TBI (mTBI). Among these, only 10% will have a brain lesion visible via CT scan. A triage biomarker would help clinicians to identify patients with mTBI who are at risk of developing a brain lesion and require a CT scan. The brain cells damaged by the shearing, tearing and stretching of a TBI event set off inflammation cascades. These cause altered concentrations of a high number of both pro inflammatory and anti-inflammatory proteins. This study aimed to discover a novel diagnostic biomarker of mTBI by investigating a broad panel of inflammation biomarkers and their capacity to correctly identify CT-positive and CT-negative patients. Patients enrolled in this study had been diagnosed with mTBI, had a GCS score of 15 and suffered from at least one clinical symptom. There were nine patients in the discovery group, 45 for verification, and 133 mTBI patients from two different European sites in the validation cohort. All patients gave blood samples, underwent a CT scan and were dichotomised into CT-positive and CT negative groups for statistical analyses. The ability of each protein to classify patients was evaluated with sensitivity set at 100%. Three of the 92 inflammation proteins screened-MCP-1, MIP-1alpha and IL-10 -were further investigated in the verification group, and at 100% sensitivity their specificities reached 7%, 0% and 31%, respectively. IL-10 was validated on a larger cohort in comparison to the most studied mTBI diagnostic triage protein to date, S100B. Levels of both proteins were significantly higher in CT-positive than in CT-negative patients (p < 0.001). S100B's specificity at 100% sensitivity was 18% (95% CI 10.8-25.2), whereas IL-10 reached a specificity of 27% (95% CI 18.9-35.1). These results showed that IL-10 might be an interesting and clinically useful diagnostic tool, capable of differentiating between CT-positive and CT-negative mTBI patients. PMID- 29466476 TI - PD-L1 is a positive prognostic factor in squamous cell carcinoma of the nasal vestibule. AB - BACKGROUND: Aim was to analyse the role of PD-L1 in squamous cell carcinomas of the nasal vestibule. Advanced squamous cell carcinoma of the nasal vestibule is a highly aggressive tumour. The role of PD-L1 expression is unclear in this tumour type. METHODOLOGY: Forty-six patients diagnosed between 1995 and 2014 were analyzed. Baseline characteristics and outcome were correlated to immunohistochemical staining of PD-L1. PD-L1 positivity of tumour cells and tumour infiltrating immune cells (TIIC) was defined by any staining of more than 1% of the tumour cells. RESULTS: PD-L1 expression was interpretable in 31 of 46 patients (67.4%). PD-L1 positivity was present in 14 (45.2%) patients tumour cells and 17 (54.8%) patients TIIC. PD-L1 positivity of tumour cells was associated with a favourable disease free survival (p=0.019). CONCLUSIONS: Positivity for PD-L1 in tumour cells is a prognostic factor in squamous cell carcinoma of the nasal vestibule and might enable a patient-tailored treatment. PMID- 29466477 TI - mySinusitisCoach: patient empowerment in chronic rhinosinusitis using mobile technology. AB - Mobile health technology is emerging to take a prominent position in the management of chronic diseases. These technologies aim at enhancing patient empowerment via education and self-management. To date, of all the different apps available for patients with sinus disease, none were developed by medical experts dealing with chronic rhinosinusitis (CRS). The European Forum for Research and Education in Allergy and Airway diseases (EUFOREA) has undertaken a multi stakeholder approach for designing, developing and implementing a tool to support CRS patients in monitoring their symptoms and to provide patients with a digital support platform containing reliable medical information about their disease and treatment options. mySinusitisCoach has been developed by medical experts dealing with CRS in close collaboration with patients, primary care physicians and community pharmacists, meeting the needs of both patients and health care providers. From a research perspective, the generation of real life data will help to validate clinical studies, patient stratification and improve understanding of the socio-economic impact of CRS, thereby paving the way for better treatment strategies. PMID- 29466478 TI - The Effect of Ferrous Nano-oxide Particles on Physiological Traits and Nutritional Compounds of Soybean ( Glycine max L.) Seed. AB - Soybean (Glycine max L.) seed contains amounts of protein, lipid, carbohydrate and mineral elements, which protein and lipid have been known as a main part for soybean's trade value. In this study, in order to investigate the effect of ferrous nano-oxide particles on nutritional compounds of soybean seed, an experiment with 5 treatments and 3 replications was conducted as a randomized complete block design. Treatments were 5 concentrations of ferrous nano-oxide particles including 0, 0.25, 0.5, 0.75 and 1 g L-1 which were sprayed 3 times at 4 and 8 leaves stage and pod initiation. Lipid and protein contents, fatty acids profile, some of mineral elements such as Fe, Mg, Ca and P, chlorophyll a, b and total chlorophyll content were determined. Results showed that solution containing ferrous nano-oxide particles had significant effect on nutritional compounds of soybean seed (P<0.01) compared to control. The highest content of lipid and protein (25.4 and %33.8, respectively) observed by applying 0.75 g L-1 of ferrous nano-oxide and the lowest content was also in control. Changes in the trends of fatty acids profile (palmitic, oleic, linoleic and linolenic acids), some of mineral elements (Fe, Mg, Ca and P) and chlorophyll contents were similar to lipid and protein levels which by increasing in concentration of ferrous nano oxide from 0 to 0.75 g L-1 all measured parameters also increased, but reduction in all parameters was observed in concentration from 0.75 to 1 g L-1. In conclusion, application of 0.75 to 1 g L-1 ferrous nano-oxide had the best effect on the nutrient composition of soybean seed. PMID- 29466479 TI - Tree community variation in a tropical continental island according to slope aspect and human interference. AB - Associating description of unrecorded tropical tree community structure to sampling approaches that can help determine mechanisms behind floristic variation is important to further the comprehension of how plant species coexist at tropical forests. Thus, this study had the goals of (i) evaluating tree community structure on the continental island of Marambaia (23 degrees 4'37.09"S; 43 degrees 59'2.15"W) and (ii) testing the prediction that there are local scale changes in a tropical tree community structure between slopes facing different geographic orientation and with distinct human interference history. We established 60 (0.6 ha) sampling units in three different slope sites with distinct predominant geographic orientation and human interference. We sampled all woody trees with diameter at breast height (dbh) >= 5 cm. We found a total of 1.170 individuals representing 220 species, 120 genera and 50 families. The overall tree community structure and structural descriptors (abundance of individuals, basal area, species richness and diversity) varied extensively between the sites. The evidence presented here supports that local scale topography variations and human interference history can be important factors contributing to the known floristic heterogeneity of the Atlantic Rainforest. Future work on the study area should focus on disentangling effects from distinct causal factors over tree community variation and species occurrence. PMID- 29466480 TI - Evaluation of growth performance and gastro-intestinal parameters on the response of weaned piglets to dietary organic acids. AB - Two experiments (E) were carried out to evaluate the effects of fumaric acid and an acidifier blend [composed by calcium formate, calcium lactate and medium-chain fatty acids (capric and caprylic)] in piglet diets containing colistin (40 ppm) or halquinol (120 ppm) on performance, diarrhea incidence (E1), organs relative weight, pH values, intestinal morphometry and microbiota (E2). In E1, 192 and E2, 24 piglets weaned at 21-day-old were randomly assigned to blocks with 2x2 factorial arrangement of treatments [absence or presence of fumaric acid x absence or presence of acidifier blend], six replicates of eight (E1) and one piglet per pen (E2). For E1, the treatments were control (CD): no acidifier product + 40 ppm of colistin, FA: fumaric acid in absence of acidifier blend, AB: acidifier blend in absence of fumaric acid and, AF+AB: presence of fumaric acid and acidifier blend. For E2, the pre-starter I diet were used and the same treatments as E1 evaluated. No treatment effects (P>0.05) were observed on performance, diarrhea incidence (E1), gut pH values and duodenum morphometry of piglets (E2). However, the addition of AB increased (P<0.05) large intestine relative weight and, FA addition decreased (P<0.05) pancreas relative weight, jejunum villi height and, total coliform and E. coli counts in cecum. The inclusion of FA and AB in diets containing colistin or halquinol did not improve performance, although FA exerted an inhibitory effect on cecum microbiota.

AB - The wall of the diaphragm can be affected by congenital or acquired alterations which allow the passage of viscera between the abdominal and chest cavities, allowing the formation of a diaphragmatic hernia. We characterized morphology and performed biometrics of the diaphragm in the common squirrel monkey Saimiri sciureus. After fixation, muscle fragments were collected and processed for optical microscopy. In this species the diaphragm muscle is attached to the lung by phrenopericardial ligament. It is also connected to the liver via the coronary and falciform ligaments. The muscle is composed of three segments in total: 1) sternal; 2) costal, and 3) a segment consisting of right and left diaphragmatic pillars. The anatomical structures analyzed were similar to those reported for other mammals. Histological analysis revealed stable, organized muscle fibers with alternation of light and dark streaks, indicating transverse striation.

AB - Among weeds, morning glories comprise a very important group of climbing plants that infest sugarcane crops. The objective of this study was to evaluate the shoot and root interference of Merremia cissoides on the initial growth of sugarcane cultivar RB 966928. The experiment consisted of five treatment groups: (i) sugarcane monocropping, (ii) morning glory monocropping, (iii) sugarcane intertwined with morning glory but inseparate boxes, (iv) sugarcane intertwined with morning glory in attached boxes and (v) sugarcane with morning glory in attached boxes with morning glory prevented from intertwining with the sugarcane. The experimental design consisted of randomized blocks with four replicates. Merremia cissoides adversely affected the initial growth of the RB 966928 sugarcane starting at 90 days after transplanting (DAT). This effect increased with the time of intercropping, reaching at 180 DAT with a reduction of 57.3% in height,15.5% in stalk diameter, 90.4% in leaf areas, 86.6 and 75.2% in stalk and leaf dry mass, respectively. These reductions primarily due to the weed intertwining with the sugarcane plants because the weed had a physical choking and shading effect. This negative effect of morning glory on the sugarcane plants increased when they shared the substrate (i.e., when they competed for space and water), which also adversely affected weed growth, reducing 50.2% leaf areas and 42.1% shoot dry mass. The leaf area and the stalk and leaf dry mass of sugarcane are the characteristics more sensitive to the weed interference. Thus, both the shoot and root of M. cissoides interferes negatively in the growth of sugarcane, with the effect proportional to the period of coexistence, highlighting the detrimental effect on the stem (greater economic interest), and may also compromise the mechanical harvesting of the crop.

AB - Native to subtropical region of South America, yerba mate is responsive to P under some conditions, but the degree of influence of genetic and soil on the growth and composition of the leaf is unknown. The aim of study was to evaluate plant growth, nutrients and potentially toxic elements in leaves of yerba mate clones in response to P application in acid soils. In greenhouse condition, two yerba mate clone seedlings were grown (210 days) in pots, each clone in a completely randomized design in factorial scheme (with and without P; four acid soils). The elemental composition of leaves and the growth of plants were determined. Phosphorus promoted plant growth, but this was not accompanied by increased P in leaf tissue in all conditions tested. The P effect on the elemental composition varied: decrease/null (N, K, Mg, Mn, Cu, Ni, B, Mo, Al, Cd); increase/null (C/N, C, Ca, Fe, V); increase/decrease/null (Zn, Ba, Pb) and; null (Cr). The soils affect the elemental composition of the leaves, especially Mn, with accumulation greater than 1000 mg kg-1. The Ba, Pb, Al and Zn in the leaves varied among clones. Yerba mate response to P was affected by edaphic and plant factors. PMID- 29466484 TI - The predator Coenosia Attenuata Stein (Diptera, Muscidae) on cultivated plants from Brazil. AB - Coenosia attenuata Stein (1903) is a predatory fly that is commonly found in greenhouses and open fields preying on whiteflies, leafminers, psocopterans and other insects. The species is widespread in the Old World and its distribution has expanded in recent times to Neotropical countries including Chile, Colombia, Costa Rica, Ecuador and Peru. We report here for the first time the presence of C. attenuata in Brazil, occurring in different sites in the State of Ceara (Northeastern Brazil). Expansion of the distribution range of this muscid to the eastern parts of South America opens up the possibility of applying the beneficial predator as a biological control agent for protected crops of the region. PMID- 29466485 TI - Autonomic and Vascular Control in Prehypertensive Subjects with a Family History of Arterial Hypertension. AB - BACKGROUND: Individuals with a family history of systemic arterial hypertension (FHSAH) and / or prehypertension have a higher risk of developing this pathology. OBJECTIVE: To evaluate the autonomic and vascular functions of prehypertensive patients with FHSAH. METHODS: Twenty-five young volunteers with FHSAH, 14 normotensive and 11 prehypertensive subjects were submitted to vascular function evaluation by forearm vascular conductance(VC) during resting and reactive hyperemia (Hokanson(r)) and cardiac and peripheral autonomic modulation, quantified, respectively, by spectral analysis of heart rate (ECG) and systolic blood pressure (SBP) (FinometerPRO(r)). The transfer function analysis was used to measure the gain and response time of baroreflex. The statistical significance adopted was p <= 0.05. RESULTS: Pre-hypertensive individuals, in relation to normotensive individuals, have higher VC both at rest (3.48 +/- 1.26 vs. 2.67 +/- 0.72 units, p = 0.05) and peak reactive hyperemia (25, 02 +/- 8.18 vs. 18.66 +/- 6.07 units, p = 0.04). The indices of cardiac autonomic modulation were similar between the groups. However, in the peripheral autonomic modulation, greater variability was observed in prehypertensive patients compared to normotensive individuals (9.4 [4.9-12.7] vs. 18.3 [14.8-26.7] mmHg2; p < 0.01) and higher spectral components of very low (6.9 [2.0-11.1] vs. 13.5 [10.7-22.4] mmHg2, p = 0.01) and low frequencies (1.7 [1.0-3.0] vs. 3.0 [2.0-4.0] mmHg2, p = 0.04) of SBP. Additionally, we observed a lower gain of baroreflex control in prehypertensive patients compared to normotensive patients (12.16 +/- 4.18 vs. 18.23 +/- 7.11 ms/mmHg, p = 0.03), but similar delay time (-1.55 +/- 0.66 vs. 1.58 +/- 0.72 s, p = 0.90). CONCLUSION: Prehypertensive patients with FHSAH have autonomic dysfunction and increased vascular conductance when compared to normotensive patients with the same risk factor. PMID- 29466486 TI - Sports Practices and Cardiovascular Risk in Teenagers. AB - BACKGROUND: Cardiovascular diseases are the leading cause of deaths in the world, and many events could be prevented by healthy life habits. OBJECTIVES: To compare the occurrence of cardiovascular risk factors in adolescents enrolled at public schools in the city of Rio de Janeiro, including a renowned school for sport practices. METHODS: Cross-sectional study, convenience sampling of 422 students enrolled at the Experimental Olympic Gymnasium (EOG) and at Figueiredo Pimentel School (FP). Using descriptive analyses, continuous variables were expressed as mean and standard deviation or median and interquartile ranges, and the Student's t-test or the chi-square test, respectively, was used for comparisons. The sports were classified according to the metabolic equivalent of task (MET) (below or above 5). RESULTS: We included 274 students enrolled at the EOG and 148 at FP. Mean age was similar between schools -12.5 +/- 1.6 years at FP and 12.6 +/- 0.9 at the EOG; 65.5% of the students at FP and 43.8% of the students at the EOG were female (p < 0.01). Significant differences in the prevalence of hypertension (20% vs. 6.3%, p < 0.01) and borderline cholesterol levels (27.7% vs. 17.3%, p = 0.01) were found between FP and EOG students, respectively. CONCLUSION: High prevalence of hypertension, overweight/obesity and altered blood lipid profile was found in this group of adolescents. Regular sports training program combined with little influence of their eating habits outside school may contribute to a better metabolic profile and reduction in cardiovascular risk factors in students. Public health measures are also need. PMID- 29466487 TI - High-Intensity Interval Training in Heart Transplant Recipients: A Systematic Review with Meta-Analysis. AB - Heart transplantation (HTx) is considered an efficient and gold-standard procedure for patients with end-stage heart failure. After surgery, patients have lower aerobic power (VO2max) and compensatory hemodynamic responses. The aim of the present study was to assess through a systematic review with meta-analysis whether high-intensity interval training (HIIT) can provide benefits for those parameters. This is a systematic review with meta-analysis, which searched the databases and data portals PubMed, Web of Science, Scopus, Science Direct and Wiley until December 2016 (pairs). The following terms and descriptors were used: "heart recipient" OR "heart transplant recipient" OR "heart transplant" OR "cardiac transplant" OR "heart graft". Descriptors via DeCS and Mesh were: "heart transplantation'' OR "cardiac transplantation". The words used in combination (AND) were: "exercise training" OR "interval training" OR "high intensity interval training" OR "high intensity training" OR "anaerobic training" OR "intermittent training" OR "sprint training". The initial search identified 1064 studies. Then, only those studies assessing the influence of HIIT on the post-HTx period were added, resulting in three studies analyzed. The significance level adopted was 0.05. Heart transplant recipients showed significant improvement in VO2peak, heart rate and peak blood pressure in 8 to 12 weeks of intervention. PMID- 29466488 TI - Uninterrupted Use of Oral Anticoagulants for the Ablation of Atrial Flutter: A Single Center Cohort of 154 Patients. AB - BACKGROUND: The uninterrupted use of oral anticoagulation (OAC) with vitamin K antagonists (VKAs) for electrophysiology procedures has been more and more recommended. The clinical practice in our service recommends the continuous use of these drugs for atrial flutter ablation. There is little evidence as to the uninterrupted use of non-vitamin K antagonist oral anticoagulants (NOACs) in this scenario. OBJECTIVE: To compare the rates of complications related with the uninterrupted use of different types of oral anticoagulants in patients referred to atrial flutter (AFL) ablation. METHODS: Historical, single-center cohort of ablation procedures by AFL conducted from November 2012 to April 2016. The primary outcome was the occurrence of hemorrhagic or embolic complication during the procedure. The secondary outcome was the occurrence of stroke or transient ischemic attack (TIA) in follow-up. The statistical significance level was 5%. RESULTS: There were 288 ablations per AFL; 154 were carried out with the uninterrupted use of OAC (57.8% with VKA and 42.2% with NOAC). Mean age was 57 +/ 13 years. The rate of hemorrhagic complication during the procedure was 3% in each group (p = NS). The rate of stroke/TIA was, respectively, of 56/1,000 people year in the VKA group against zero/1,000 people-year in the NOAC group (p = 0.02). CONCLUSION: In our population there were no hemorrhagic complications regarding the procedure of OAC use uninterruptedly, including NOACs. There was higher occurrence of stroke/TIA in the follow-up of the group of patients undergoing VKAs; however, this difference may not only be a result of the type of OAC used. PMID- 29466489 TI - Moderate Continuous Aerobic Exercise Training Improves Cardiomyocyte Contractility in Beta1 Adrenergic Receptor Knockout Mice. AB - BACKGROUND: The lack of cardiac beta1-adrenergic receptors (beta1-AR) negatively affects the regulation of both cardiac inotropy and lusitropy, leading, in the long term, to heart failure (HF). Moderate-intensity aerobic exercise (MCAE) is recommended as an adjunctive therapy for patients with HF. OBJECTIVE: We tested the effects of MCAE on the contractile properties of left ventricular (LV) myocytes from beta1 adrenergic receptor knockout (beta1ARKO) mice. METHODS: Four- to five-month-old male wild type (WT) and beta1ARKO mice were divided into groups: WT control (WTc) and trained (WTt); and beta1ARKO control (beta1ARKOc) and trained (beta1ARKOt). Animals from trained groups were submitted to a MCAE regimen (60 min/day; 60% of maximal speed, 5 days/week) on a treadmill, for 8 weeks. P <= 0.05 was considered significant in all comparisons. RESULTS: The beta1ARKO and exercised mice exhibited a higher (p < 0.05) running capacity than WT and sedentary ones, respectively. The beta1ARKO mice showed higher body (BW), heart (HW) and left ventricle (LVW) weights, as well as the HW/BW and LVW/BW than WT mice. However, the MCAE did not affect these parameters. Left ventricular myocytes from beta1ARKO mice showed increased (p < 0.05) amplitude and velocities of contraction and relaxation than those from WT. In addition, MCAE increased (p < 0.05) amplitude and velocities of contraction and relaxation in beta1ARKO mice. CONCLUSION: MCAE improves myocyte contractility in the left ventricle of beta1ARKO mice. This is evidence to support the therapeutic value of this type of exercise training in the treatment of heart diseases involving beta1-AR desensitization or reduction. PMID- 29466490 TI - Heart Transplantation for Peripartum Cardiomyopathy: A Single-Center Experience. AB - BACKGROUND: Peripartum cardiomyopathy is an idiopathic disorder defined by the occurrence of acute heart failure during late pregnancy or post-partum period in the absence of any other definable cause. Its clinical course is variable and severe cases might require heart transplantation. OBJECTIVE: To investigate long term outcomes after heart transplantation (HT) for peripartum cardiomyopathy (PPCM). METHODS: Out of a single-center series of 1938 HT, 14 HT were performed for PPCM. We evaluated clinical characteristics, transplant-related complications, and long-term outcomes, in comparison with 28 sex-matched controls. Primary endpoint was death from any cause; secondary endpoints were transplant-related complications (rejection, infection, cardiac allograft vasculopathy). A value of p < 0.05 was considered of statistical significance. RESULTS: PPCM patients and matched controls were comparable for most variables (all p values > 0.05), except for a higher use of inotropes at the time of HT in PPCM group (p = 0.03). During a median follow-up of 7.7 years, 16 patients died, 3 (21.5%) in PPCM group and 13 (46.5%) in control group. Mortality was significantly lower in PPCM group (p = 0.03). No significant difference was found in terms of transplant-related complications (p > 0.05). CONCLUSIONS: Long-term outcomes following HT for PPCM are favorable. Heart transplantation is a valuable option for PPCM patients who did not recover significantly under medical treatment. PMID- 29466491 TI - The Presence and Extension of Myocardial Fibrosis in the Undetermined Form of Chagas' Disease: A Study Using Magnetic Resonance. AB - BACKGROUND: Previous data has shown that patients in the indeterminate form of Chagas disease may present myocardial fibrosis as shown on through magnetic resonance imaging (MRI). However, there is little information available regarding the degree of severity of myocardial fibrosis in these individuals. This variable has the potential to predict the evolution of Chagas' disease into its cardiac form. OBJECTIVES: To describe the frequency and extent of myocardial fibrosis evaluated using an MRI in patients in the indeterminate form, and to compare it with other forms of the disease. METHODS: Patients were admitted one after another. Their clinical history was collected and they were submitted to laboratory exams and an MRI. RESULTS: Sixty-one patients with Chagas' disease, with an average age of 58 +/- 9 years old, 17 patients in the indeterminate form, 16 in the cardiac form without left ventricular (LV) dysfunction and 28 in the cardiac form with LV dysfunction were studied. P <0.05 was considered to be statistically significant. Late enhancement was detected in 37 patients (64%). Myocardial fibrosis was identified in 6 individuals in indeterminate form (41%; 95% CI 23-66) in a proportion similar to that observed in cardiac form without LV dysfunction (44%); p = 1.0. Among the individuals with fibrosis, the total area of the affected myocardium was 4.1% (IIQ: 2.1 - 10.7) in the indeterminate form versus 2.3% (IIQ: 1-5) in the cardiac form without LV (p = 0.18). The left ventricular fraction ejection in subjects in the indeterminate form was similar to that of the individuals in the cardiac form without ventricular dysfunction (p = 0.09). CONCLUSION: The presence of fibrosis in the indeterminate form of Chagas' disease has a frequency and extension similar to that of in the cardiac form without dysfunction, suggesting that the former is part of a subclinical disease spectrum, rather than lacking cardiac involvement. PMID- 29466492 TI - Urbanization is Associated with Increased Trends in Cardiovascular Mortality Among Indigenous Populations: the PAI Study. AB - BACKGROUND: The cardiovascular risk burden among diverse indigenous populations is not totally known and may be influenced by lifestyle changes related to the urbanization process. OBJECTIVES: To investigate the cardiovascular (CV) mortality profile of indigenous populations during a rapid urbanization process largely influenced by governmental infrastructure interventions in Northeast Brazil. METHODS: We assessed the mortality of indigenous populations (>= 30 y/o) from 2007 to 2011 in Northeast Brazil (Bahia and Pernambuco states). Cardiovascular mortality was considered if the cause of death was in the ICD-10 CV disease group or if registered as sudden death. The indigenous populations were then divided into two groups according to the degree of urbanization based on anthropological criteria:9,10 Group 1 - less urbanized tribes (Funi-o, Pankararu, Kiriri, and Pankarare); and Group 2 - more urbanized tribes (Tuxa, Truka, and Tumbalala). Mortality rates of highly urbanized cities (Petrolina and Juazeiro) in the proximity of indigenous areas were also evaluated. The analysis explored trends in the percentage of CV mortality for each studied population. Statistical significance was established for p value < 0.05. RESULTS: There were 1,333 indigenous deaths in tribes of Bahia and Pernambuco (2007-2011): 281 in Group 1 (1.8% of the 2012 group population) and 73 in Group 2 (3.7% of the 2012 group population), CV mortality of 24% and 37%, respectively (p = 0.02). In 2007 2009, there were 133 deaths in Group 1 and 44 in Group 2, CV mortality of 23% and 34%, respectively. In 2009-2010, there were 148 deaths in Group 1 and 29 in Group 2, CV mortality of 25% and 41%, respectively. CONCLUSIONS: Urbanization appears to influence increases in CV mortality of indigenous peoples living in traditional tribes. Lifestyle and environmental changes due to urbanization added to suboptimal health care may increase CV risk in this population. PMID- 29466493 TI - Preventable adverse drug events in critically ill HIV patients: Is the detection of potential drug-drug interactions a useful tool? AB - OBJECTIVES: The aim of this study was to develop a strategy to identify adverse drug events associated with drug-drug interactions by analyzing the prescriptions of critically ill patients. METHODS: This retrospective study included HIV/AIDS patients who were admitted to an intensive care unit between November 2006 and September 2008. Data were collected in two stages. In the first stage, three prescriptions administered throughout the entire duration of these patients' hospitalization were reviewed, with the Micromedex database used to search for potential drug-drug interactions. In the second stage, a search for adverse drug events in all available medical, nursing and laboratory records was performed. The probability that a drug-drug interaction caused each adverse drug events was assessed using the Naranjo algorithm. RESULTS: A total of 186 drug prescriptions of 62 HIV/AIDS patients were analyzed. There were 331 potential drug-drug interactions, and 9% of these potential interactions resulted in adverse drug events in 16 patients; these adverse drug events included treatment failure (16.7%) and adverse reactions (83.3%). Most of the adverse drug reactions were classified as possible based on the Naranjo algorithm. CONCLUSIONS: The approach used in this study allowed for the detection of adverse drug events related to 9% of the potential drug-drug interactions that were identified; these adverse drug events affected 26% of the study population. With the monitoring of adverse drug events based on prescriptions, a combination of the evaluation of potential drug drug interactions by clinical pharmacy services and the monitoring of critically ill patients is an effective strategy that can be used as a complementary tool for safety assessments and the prevention of adverse drug events. PMID- 29466494 TI - Granulocyte Colony-Stimulating Factor Combined with Methylprednisolone Improves Functional Outcomes in Rats with Experimental Acute Spinal Cord Injury. AB - OBJECTIVES: To evaluate the effects of combined treatment with granulocyte colony stimulating factor (G-CSF) and methylprednisolone in rats subjected to experimental spinal cord injury. METHODS: Forty Wistar rats received a moderate spinal cord injury and were divided into four groups: control (no treatment); G CSF (G-CSF at the time of injury and daily over the next five days); methylprednisolone (methylprednisolone for 24 h); and G-CSF/Methylprednisolone (methylprednisolone for 24 h and G-CSF at the time of injury and daily over the next five days). Functional evaluation was performed using the Basso, Beattie and Bresnahan score on days 2, 7, 14, 21, 28, 35 and 42 following injury. Motor evoked potentials were evaluated. Histological examination of the spinal cord lesion was performed immediately after euthanasia on day 42. RESULTS: Eight animals were excluded (2 from each group) due to infection, a normal Basso, Beattie and Bresnahan score at their first evaluation, or autophagy, and 32 were evaluated. The combination of methylprednisolone and G-CSF promoted greater functional improvement than methylprednisolone or G-CSF alone (p<0.001). This combination also exhibited a synergistic effect, with improvements in hyperemia and cellular infiltration at the injury site (p<0.001). The groups displayed no neurophysiological differences (latency p=0.85; amplitude p=0.75). CONCLUSION: Methylprednisolone plus G-CSF promotes functional and histological improvements superior to those achieved by either of these drugs alone when treating spinal cord contusion injuries in rats. Combining the two drugs did have a synergistic effect. PMID- 29466495 TI - Monitoring auditory cortical plasticity in hearing aid users with long latency auditory evoked potentials: a longitudinal study. AB - OBJECTIVE: The objective of this study was to compare long-latency auditory evoked potentials before and after hearing aid fittings in children with sensorineural hearing loss compared with age-matched children with normal hearing. METHODS: Thirty-two subjects of both genders aged 7 to 12 years participated in this study and were divided into two groups as follows: 14 children with normal hearing were assigned to the control group (mean age 9 years and 8 months), and 18 children with mild to moderate symmetrical bilateral sensorineural hearing loss were assigned to the study group (mean age 9 years and 2 months). The children underwent tympanometry, pure tone and speech audiometry and long-latency auditory evoked potential testing with speech and tone burst stimuli. The groups were assessed at three time points. RESULTS: The study group had a lower percentage of positive responses, lower P1-N1 and P2-N2 amplitudes (speech and tone burst), and increased latencies for the P1 and P300 components following the tone burst stimuli. They also showed improvements in long-latency auditory evoked potentials (with regard to both the amplitude and presence of responses) after hearing aid use. CONCLUSIONS: Alterations in the central auditory pathways can be identified using P1-N1 and P2-N2 amplitude components, and the presence of these components increases after a short period of auditory stimulation (hearing aid use). These findings emphasize the importance of using these amplitude components to monitor the neuroplasticity of the central auditory nervous system in hearing aid users.

PMID- 29466509 TI - Translation and cross-cultural adaptation of the Detailed Assessment of Speed of Handwriting 17+ to Brazilian Portuguese: conceptual, item and semantic equivalence. AB - PURPOSE: Perform a cross-cultural adaptation of the Detailed Assessment of Speed of Handwriting 17+ (DASH 17+) for Brazilians. METHODS: Evaluation of (1) conceptual, item and (2) semantic equivalence, with assistance of four translators and application of a pilot study to 36 students. RESULTS: (1) The concepts and items are equivalent in the British and Brazilian cultures. (2) Adaptations were made concerning the English language pangram used in copying tasks and selection of the lower-case, cursive handwriting in the alphabet writing task. Application of the pilot study verified acceptability and understanding of the proposed tasks by the students. CONCLUSION: The Brazilian Portuguese version of the DASH 17+ was presented after finalization of the conceptual, item and semantic equivalence of the instrument. Further studies on psychometric properties should be conducted with the purpose of measuring the speed of handwriting in youngsters and adults with greater reliability and validity to the procedure. PMID- 29466510 TI - Educational intervention assessment aiming the hearing preservation of workers at a hospital laundry. AB - OBJECTIVE: Evaluate the effectiveness of educational interventions on hearing health developed at a hospital laundry. METHODS: Quantitative assessment conducted at a hospital laundry. The study sample comprised 80 workers of both genders divided into two groups: Study Group (SG) and Control Group (CG). The educational interventions in hearing preservation were evaluated based on a theoretical approach using the Participatory Problem-based Methodology in five workshops. To assess the results of the workshops, an instrument containing 36 questions on knowledge, attitudes, and practices in hearing preservation at work was used. Questionnaires A and B were applied prior to and one month after intervention, respectively. The answers to both questionnaires were analyzed by group according to gender and schooling. RESULTS: Results of the pre-intervention phase showed low scores regarding knowledge about hearing health in the work setting for both groups, but significant improvement in knowledge was observed after intervention in the SG, with 77.7% of the answers presenting significant difference between the groups. There was also an improvement in the mean scores, with 35 responses (95.22%) presenting scores >4 (considered adequate). The women presented lower knowledge scores than the men; however, these differences were not observed in the SG after the workshops. Schooling was not a relevant factor in the assessment. CONCLUSION: The educational proposal grounded in the Participatory Problem-based Methodology expanded knowledge about hearing health at work among the participants. PMID- 29466511 TI - Comparison between different methods of breast implant volume choice and degree of postoperative satisfaction. AB - OBJECTIVES: to assess the degree of patient satisfaction after undergoing breast augmentation and compare three different, easy, inexpensive and universal methods of preoperative choice of breast implant volume. METHODS: a prospective study was carried out at University Hospital Pedro Ernesto of State University of Rio de Janeiro, in 94 women from Rio de Janeiro, aged 18 to 49 years, submitted to breast augmentation mammaplasty with breast implant due to hypomastia. All implants were textured, with a round base and high projection and were introduced into the retroglandular space through an inframammary access. The patients were divided into three groups: Control, Silicone and MamaSize(r), with 44, 25 and 25 patients, respectively. Satisfaction questionnaires were applied in the pre and postoperative periods by the same evaluator, through the visual analogue scale, in which '0' meant very unsatisfied and '100' very satisfied for the four variables: shape, size, symmetry and consistency. The degree of satisfaction with the surgical scar was also assessed in the postoperative period. RESULTS: when the preoperative and postoperative satisfaction levels were compared, there was a difference in all variables for the three groups, with statistical significance. However, when the postoperative data were compared with each other, there was no significant difference. The degree of satisfaction with the surgical scar was high. CONCLUSION: the augmentation mammaplasty with breast implant had a high index of satisfaction among patients. However, there was no difference in the degree of satisfaction in the postoperative period between the three methodologies of breast volume measurement. PMID- 29466512 TI - The role of computerized tomography in penetrating abdominal trauma. AB - OBJECTIVE: to evaluate the role of abdominal computed tomography in the management of penetrating abdominal trauma. METHODS: we conducted a historical cohort study of patients treated for penetrating trauma in the anterior abdomen, dorsum or thoracoabdominal transition, that were submitted to a computed tomography carried out on admission. We evaluated the location of the wound and the presence of tomographic findings, and the management of these patients as for nonoperative treatment or laparotomy. We calculated the sensitivity and specificity of computed tomography according to the evolution of the nonoperative treatment or the surgical findings. RESULTS: we selected 61 patients, 31 with trauma to the anterior abdomen and 30 to the dorsum or thoracoabdominal transition. The mortality rate was 6.5% (n=4), all in the late postoperative period. Eleven patients with trauma to the anterior abdomen were submitted to nonoperative treatment, and 20, to laparotomy. Of the 30 patients with trauma to the dorsum or thoracoabdominal transition, 23 underwent nonoperative treatment and seven, laparotomy. There were three nonoperative treatment failures. In penetrating trauma of the anterior abdomen, the sensitivity of computed tomography was 94.1% and the negative predictive value was 93.3%. In dorsal or thoracoabdominal transition lesions, the sensitivity was 90% and the negative predictive value was 95.5%. In both groups, the specificity and the positive predictive value were 100%. CONCLUSION: the accuracy of computed tomography was adequate to guide the management of stable patients who could be treated conservatively, avoiding mandatory surgery in 34 patients and reducing the morbidity and mortality of non-therapeutic laparotomies. PMID- 29466513 TI - The experience of an Academic League: the positive impact on knowledge about trauma and emergency. AB - OBJECTIVE: to evaluate the knowledge growth of the members of the Trauma, Resuscitation and Emergency League in comparison with a nonparticipating group, with similar characteristics, at the Fluminense Federal University. METHODS: we evaluated 50 league members and 50 non-members (control group) through questionnaires applied at the beginning and end of a school year. We used a generalized linear model, with interaction effect between groups and tests (multiple comparisons with Bonferroni correction). We included the following control variables: gender, period, age, and attendance to some other course on a similar topic. RESULTS: there was an increase of 22 percentage points (p<0.001) for the group with more than 75% presence in the League compared with the eight points in the control group (p<0.05). There was no statistically significant growth for the group with less than 75% presence. CONCLUSION: the growth of knowledge was significantly higher in the group that assiduously participated in the League, which reinforces its importance in complementing the traditional content of medical courses. PMID- 29466514 TI - Basic ultrasound training assessment in the initial abdominal trauma screening. AB - OBJECTIVE: to verify the efficiency and usefulness of basic ultrasound training in trauma (FAST - Focused Assessment with Sonography in Trauma) for emergency physicians in the primary evaluation of abdominal trauma. METHODS: a longitudinal and observational study was carried out from 2015 to 2017, with 11 emergency physicians from Hospital Universitario do Oeste do Parana, submitted to ultrasound training in emergency and trauma (USET(r) - SBAIT). FAST results started to be collected two months after the course. These were compared with a composite score of complementary exams and surgical findings. Information was stored in a Microsoft Excel program database and submitted to statistical analysis. RESULTS: FAST was performed in 120 patients. In the study, 38.4% of the assessed patients had a shock index >=0.9. The composite score detected 40 patients with free peritoneal fluid, whereas FAST detected 27 cases. The method sensitivity was 67.5%, specificity was 98.7%, the positive predictive value was 96.4%, the negative predictive value was 85.39% and accuracy was 88%. All those with a positive FAST had a shock index >=0.9. Fifteen patients with positive FAST and signs of instability were immediately submitted to surgery. CONCLUSIONS: the basic training of emergency physicians in FAST showed efficiency and usefulness in abdominal trauma assessment. Due to its low cost and easy implementation, this modality should be considered as a screening strategy for patients with abdominal trauma in health systems.

AB - OBJECTIVE: The aim of this study was to analyze the effects of individual low socioeconomic status (SES) and deprived geographical area (GA) on the occurrence of isolated cleft lip with or without cleft palate (CL+/-P) in Argentina. METHODS: This case-control study included 577 newborns with isolated CL+/-P and 13 344 healthy controls, born between 1992 and 2001, from a total population of 546 129 births in 39 hospitals in Argentina. Census data on unsatisfied basic needs were used to establish the degree of geographical area deprivation. An SES index for each individual was established, using maternal age, gravidity, low paternal and maternal education, and low-level paternal occupation. Logistic regression was used to assess the effects of low SES and of deprived GA on CL+/ P. RESULTS: A slightly increased risk of CL+/-P was observed in mothers with a low SES, while a deprived GA showed no effect. Native ancestry, acute maternal illnesses, and poor prenatal care were significant risk factors for CL+/-P for the mothers with low SES, after using propensity scores to adjust for the demographic characteristics in cases and controls. CONCLUSIONS: Low individual SES slightly increased the risk for CL+/-P, but a deprived GA did not have that effect. There was no interaction between individual SES and deprived GA. Factors related to low individual SES-including poor prenatal care, low parental education, lack of information, and lifestyle factors-should be primarily targeted as risk factors for CL+/-P rather than factors related to a deprived place of residence.

AB - OBJECTIVE: The objectives of this study were to: 1) raise awareness of the volume of quality health information on the Internet; 2) explore perceptions of information professionals with regard to the use of qualified sources for health decision-making; and 3) make recommendations that facilitate strengthening health worker capacities and institutional competencies related to digital literacy. METHODS: A non-experimental, descriptive cross-sectional study was conducted with a non-probability sample of 32 information professionals from nine countries. Internet information was compiled on the volume of content in Internet tools, social networks, and health information sources. Searches in English and Spanish were carried out using the keywords Ebola, Zika, dengue, chikungunya, safe food, health equity, safe sex, and obesity. Finally, information was obtained on opportunities for formal education on the subjects of digital literacy, information management, and other related topics. RESULTS: Selecting only four diseases with a high impact on public health in May 2016 and averaging minimum review time for each information product, it would take more than 50 years without sleeping to consult everything that is published online about dengue, Zika, Ebola, and chikungunya. CONCLUSION: We conclude that public health would benefit from: health institutions implementing formal knowledge management strategies; academic health sciences institutions incorporating formal digital literacy programs; and having health workers who are professionally responsible and functional in the information society. PMID- 29466517 TI - Potential occurrence of Zika from subtropical to temperate Argentina considering the basic reproduction number (R0). AB - OBJECTIVE: To assess the potential occurrence of Zika transmission throughout Argentina by the mosquito Aedes aegypti considering the basic reproduction number (R0). METHODS: A model originally developed for dengue was adapted for Zika. R0 was estimated as a function of seven parameters, three of them were considered temperature-dependent. Seasonal Zika occurrence was evaluated in 9 locations representing different climatic suitability for the vector. Data of diary temperatures were extracted and included in the model. A threshold of R0 = 1 was fixed for Zika occurrence. Sensitivity analyses were performed to evaluate the uncertainty around the results. RESULTS: Zika transmission has the potential to occur in all studied locations at least in some moment of the year. In the northern region, transmission might be possible throughout the whole year or with an interruption in winter. The maximum R0 was estimated in 6.9, which means an average of 7 secondary cases from a primary case. The probabilistic sensitivity analysis showed that during winter the transmission can only be excluded in the southern fringe of geographic distribution of the vector and in part of central Argentina. CONCLUSION: Zika virus has the potential to be transmitted in Argentina throughout the current geographic range of the mosquito vector. Although the transmission would be mainly seasonal, the possibility of winter transmission cannot be excluded in northern and central Argentina, meaning that there is a potential endemic maintenance of the disease.

PMID- 29466519 TI - A road map for leptospirosis research and health policies based on country needs in Latin America. AB - This report summarizes the presentations, discussions and the recommendations coming from the Oswaldo Cruz Institute/FIOCRUZ International Workshop for Leptospirosis Research Based on Country Needs and the 5th Global Leptospirosis Environmental Action Network meeting, which was held in the city of Rio de Janeiro, Brazil, 10-12 November 2015. The event focused on health policy and worked to develop a road map as a consensus document to help guide decision making by policymakers, funding bodies, and health care professionals. The direction that leptospirosis research should take in the coming years was emphasized, taking into account the needs of countries of Latin America, as well as experiences from other world regions, as provided by international experts. The operational concepts of "One Health" and translational research underlaid the discussions and the resulting recommendations. Despite the wide geographic distribution of leptospirosis and its impact in terms of incidence, morbidity, and mortality, leptospirosis is not yet considered a "tool-ready" disease for global initiatives. Surveillance programs need new tools and strategies for early detection, prevention, and follow-up. The major recommendations developed at the Rio meeting cover both health policy and research. The health policy recommendations should be taken into account by decisionmakers, government officials, and the Pan American Health Organization. The priorities for research, technological development, and innovation should be considered by research institutions, universities, and stakeholders. PMID- 29466520 TI - ? PMID- 29466521 TI - Prolonged Zika virus viremia in a patient with Guillain-Barre syndrome in Trinidad and Tobago. AB - An emerging mosquito-borne flavivirus, Zika virus (ZIKV) is a significant public health concern because of the syndromes associated with the infection. In addition, ZIKV is considered a major problem due to large-scale spread of the disease and the possible clinical complications for the central nervous system, especially Guillain-Barre syndrome (GBS) and microcephaly. Since the introduction of ZIKV in the Caribbean, molecular detection of the viral RNA has been utilized as a more specific and sensitive approach to demonstrating acute infection. However, it is generally accepted that the virus has a short viremic period, generally less than 5 days. Serologic testing has the inconvenience of strong cross-reactivity among flaviviruses, such as dengue and yellow fever. As part of the laboratory surveillance activities for Zika and other arboviruses at the Caribbean Public Health Agency, in 2016 a sample from a male who was clinically diagnosed with GBS tested positive for Zika virus by real-time polymerase chain reaction (rRT-PCR). The serum sample had been taken on day 21 after the onset of symptoms. The case had initially been characterized as a typical ZIKV infection (mild fever with a generalized maculopapular rash). Later, weakness of limbs and other peripheral neurological symptoms appeared. Enzyme-linked immunoassay (ELISA) showed that the sample was negative for IgM antibodies against Zika, Chikungunya, and dengue viruses. The plaque reduction neutralization test was positive for ZIKV. This indicated parallel development of viremia and immune response against ZIKV. Recent reports have demonstrated a longer duration of the viremia in ZIKV infections. However, our report is the first one that links the infection with extended viremia and the development in parallel of a GBS case. PMID- 29466522 TI - [Health technology assessment for decision-making in Latin America: good practice principles]. AB - OBJECTIVE: Identify the most relevant, applicable, and priority good practice principles in health technology assessment (HTA) in Latin America, and potential barriers to implementing them in the region. METHODS: HTA good practice principles postulated worldwide were identified and then explored through a deliberative process in a forum of evaluators, funders, and technology producers. RESULTS: Forty-two representatives from ten Latin American countries participated in the forum. The good practice principles postulated at the international level were considered valid and potentially applicable in Latin America. Five principles were identified as priorities and as having greater potential to be expanded at this time: transparency in carrying out HTA; involvement of stakeholders in the HTA process; existence of mechanisms to appeal decisions; existence of clear mechanisms for HTA priority-setting; and existence of a clear link between assessment and decision-making. The main challenge identified was to find a balance between application of these principles and available resources, to prevent the planned improvements from jeopardizing report production times and failing to meet decision-makers' needs. CONCLUSIONS: The main recommendation was to gradually advance in improving HTA and its link to decision-making by developing appropriate processes for each country, without attempting to impose, in the short term, standards taken from examples at the international level without adequate adaptation to the local context. PMID- 29466523 TI - [Breastfeeding and externalizing behaviors in childhood and adolescence in a birth cohort]. AB - OBJECTIVE: To assess the association between breastfeeding duration and externalizing behaviors in childhood and adolescence. METHODS: Data from the 1993 Pelotas Birth Cohort was used. Information on breastfeeding was assessed at 12 months of age. Behavior was assessed at 4 years of age using the Child Behavior Checklist (CBCL), and at ages 11 and 15 years using the Strengths and Difficulties Questionnaire (SDQ), both administered to the mother or caretaker. Of 5 249 cohort participants, those with complete data on breastfeeding and externalizing behaviors were included: 630 children at 4 years of age, 1 277 adolescents at 11 years, and 1 199 at 15 years. Poisson regression with robust variance was used to assess the association between breastfeeding duration and externalizing behaviors. RESULTS: After adjustment for confounders, children who were breastfed for least 6 months had lower risk of hyperactivity (RR = 0.54; 95%CI: 0.32-0.91) at age 11 compared to those breastfed for less than 1 month. However, no association was observed between breastfeeding duration and externalizing behaviors at ages 4 and 15. CONCLUSIONS: Although breastfeeding for at least 6 months was inversely associated with hyperactivity at 11 years of age no association was observed at 4 and 15 years of age. Further longitudinal studies should focus on other aspects influencing externalizing behaviors, such as presence of the father in the family, domestic violence and abuse, and the quality of mother-child relationship. PMID- 29466524 TI - [Social determinants of intestinal parasitism, malnutrition, and anemia: systematic review]. AB - OBJECTIVE: Characterize the publications on social determinants of intestinal parasitism, malnutrition, and anemia at the global level. METHODS: A systematic review was conducted of the scientific literature in Pubmed, Science Direct, SciELO, LILACS, and Google Scholar with eight search strategies, guaranteeing completeness and replicability, following the phases of the PRISMA guidelines. RESULTS: The review included 18 studies on malnutrition, three on parasitism, three on anemia, and two on both parasitism and malnutrition; 65.4% of the studies were from South America and 69.2% were carried out among children. The prevalence of intestinal parasitism ranged between 30.6% and 83.3%; anemia, 19.7% to 48.0%; and malnutrition, 0.0% to 67.8%. It was found that biological and psychosocial determinants were most frequently studied; the most frequently studied intermediate determinants were related to housing and income; and structural determinants were least investigated. The social determinants common to the three conditions include: living in homes with poor sanitary conditions, rural areas, inadequate housing, inadequate water supply, access barriers to the medical system, young parents with little schooling, precarious employment, and low income. CONCLUSION: The majority of publications do not conduct a multilevel analysis for individual, intermediate, or structural determinants. Greater efforts are needed in health policies that address the social determinants of inequality with respect to parasitism, malnutrition, and anemia, mainly in categories as macroeconomic policy, social class, labor market, culture, values, and territory. PMID- 29466525 TI - [Chronic diseases in the population affected by the armed conflict in Colombia, 2015]. AB - OBJECTIVE: The purpose of this study was to identify the most frequent non-mental chronic illnesses in the Colombian population affected by the armed conflict. METHODOLOGY: A cross-sectional study using data from the National Mental Health Survey 2015. The study population was stratified by sex and age and other general data were extracted, including education and poverty level, measured by the Multidimensional Poverty Index. Data analysis was based on information from people who reported having been victims of the Colombian armed conflict at some time in their lives; the frequency of presentation of non-mental chronic illnesses was reported as a measure of indirect relative risk. RESULTS: Information on 10,764 people over 18 years of age was described, this being a representative sample at the national level. It was found that 10.4% of subjects affected by the armed conflict have a high educational level (technical school or university), and that 43.6% are living in conditions of poverty or vulnerability. The non-mental chronic illnesses identified were: hypertension 20.4% (CI95%: 15.7 26.1); diabetes 6.7% (CI95%: 4.4-10.3); rheumatologic diseases 10.4% (CI95%: 7.1 14.9); gastrointestinal diseases 19.1% (CI95%: 14.5-24.7); and chronic pain 6.9% (CI95%: 4.2-11). CONCLUSIONS: The population affected by the armed conflict is apparently at greater risk of presenting non-mental chronic illnesses such as hypertension and diabetes, which shows the vulnerability of these communities. PMID- 29466526 TI - [Spatial distribution of hospital discharges of cases of viral infection from mosquito bites in Mexico in the period 2004-2014]. AB - OBJECTIVE: Determine the spatial distribution of hospital discharges of viral fever caused by mosquito bites in Mexico and characterize its historical trend in the period 2004-2014. METHODS: An exploratory cross-sectional inferential analysis was performed. The primary data were obtained from the hospital discharge registries of the National Health Information System (SINAIS) for the period 2004-2014. In order to identify clusters of reported cases, indicators of geographical association were estimated and risk areas established on the basis of environmental determinants validated with estimated relative concentration measurements. In order to determine the temporal trend and age structure of the cases, growth rates were estimated and density curves constructed. RESULTS: The geographic distribution of these hospital discharges in Mexico follows a focalized pattern. In total, a high concentration was detected in clusters made up of 20 municipalities, 9 of which were located in the state of Sinaloa. In 37% of states in the country, the concentrations of hospital discharges of viral fever cases were higher than those for the country as a whole, and their localization indices ranged from 5.79 in Sinaloa to 1.17 in Campeche. CONCLUSION: Geographic information, information on the link found between areas at high risk for transmission of infection due to the presence of the transmitting vector, and information on social conditions such as poverty are useful for designing strategies for the prevention and control of emerging arthropod-borne viral infections, such as the Zika virus, in Mexico.

PMID- 29466528 TI - [Future type 2 diabetes mellitus scenario estimated with a predictive dynamic simulation model]. AB - OBJECTIVE: Develop a predictive dynamic model to estimate future scenarios for the incidence rate of type 2 diabetes mellitus (T2DM). METHODS: A retrospective ecological study was conducted in 2013-2015 in the city of San Luis Potosi, Mexico. Secondary official data from the 58 municipalities making up the state of San Luis Potosi were analyzed. Linear correlation, multiple linear regression, and structural equations were carried out, and four predictive dynamic submodels were developed: T2DM, urban population, inhabited private dwellings that have television, and population aged 45-49 years. A holistic model was also developed. RESULTS: The structural model explains 27.2% of total variance in type 2 diabetes mellitus. Percentage of inhabited dwellings that have television weighs 4.46 non standard units on diabetes; that of urban population, 2.84; and that of population aged 45-49 years, 156.69. Estimated scenarios for T2DM per 100 000 population for the years 2015, 2020, 2025, and 2030 were 1,052.4, 1,413.7, 1,850.1, and 2,351.1 respectively. CONCLUSION: The T2DM scenario shows exponential growth from 2000 to 2030. Risk factors according to the weight they represent in occurrence of the disease were: population aged 45-49 years, inhabited private dwellings that have television, and urban population. PMID- 29466529 TI - ? PMID- 29466530 TI - Cardiac Abnormalities in Patients With Hutchinson-Gilford Progeria Syndrome. AB - Importance: Hutchinson-Gilford progeria syndrome (HGPS) is an ultrarare disorder associated with premature death due to cardiovascular events during the second decade of life. However, because of its rarity (107 identified living patients), the natural history of cardiac disease remains uncharacterized. Therefore, meaningful cardiac end points for clinical trials have been difficult to establish. Objective: To examine the course of appearance of cardiac abnormalities in patients with HGPS to identify meaningful cardiac end points for use in future clinical trials. Design, Setting, and Participants: In this prospective, cross-sectional, observational study, 27 consecutive patients with clinically and genetically confirmed classic HGPS were evaluated at a single center for 1 visit from July 1, 2014, through February 29, 2016, before initiation of treatment. Exposure: Classic HGPS. Main Outcomes and Measures: Echocardiography was used to assess ventricular and valve function using standard techniques. Diastolic left ventricular (LV) function was assessed using tissue Doppler imaging. Previously published normative data were used to adjust findings to age and body size. Results: This study included 27 patients (median age, 5.6 years; age range, 2-17 years; 15 [56%] male). Among echocardiographic indicators, LV diastolic dysfunction, defined as a tissue Doppler septal or lateral early velocity z score less than -2, was the most prevalent abnormality, seen in 16 patients (59%). Diastolic dysfunction was seen in all age groups, and its prevalence increased with age, mirroring findings seen during normal aging. Indicators of LV diastolic function were more abnormal in older patients. The z scores for lateral and septal early velocities were lower (r = -0.77, P < .001; and r = -0.66, P < .001, respectively), whereas those for the ratio of early mitral inflow velocity to early diastolic tissue Doppler myocardial velocity were higher (r = 0.80, P < .001; and r = 0.72, P < .001, respectively) in older patients. Other echocardiographic findings, including LV hypertrophy, LV systolic dysfunction, and valve disease, were less prevalent in the first decade and were seen more frequently in the second decade. Conclusions and Relevance: In this largest-to-date cohort of patients with HGPS, LV diastolic dysfunction was the most prevalent echocardiographic abnormality and its prevalence increased with aging. Echocardiographic indicators of LV diastolic function may be useful end points in future clinical trials in this patient population. PMID- 29466531 TI - Association of Increased Chronicity of Depression With HIV Appointment Attendance, Treatment Failure, and Mortality Among HIV-Infected Adults in the United States. AB - Importance: Depression commonly affects adults with HIV and complicates the management of HIV. Depression among individuals with HIV tends to be chronic and cyclical, but the association of this chronicity with HIV outcomes (and the related potential for screening and intervention to shorten depressive episodes) has received little attention. Objective: To examine the association between increased chronicity of depression and multiple HIV care continuum indicators (HIV appointment attendance, treatment failure, and mortality). Design, Setting, and Participants: The study comprised an observational clinical cohort of 5927 patients with 2 or more assessments of depressive severity who were receiving HIV primary care at 6 geographically dispersed US academic medical centers from September 22, 2005, to August 6, 2015. Main Outcomes and Measures: Missing a scheduled HIV primary care visit, detectable HIV RNA viral load (>=75 copies/mL), and all-cause mortality. Consecutive depressive severity measures were converted into a time-updated measure: percentage of days with depression (PDD), following established methods for determining depression-free days. Results: During 10 767 person-years of follow-up, the 5927 participants (5000 men, 926 women, and 1 intersex individual; median age, 44 years [range, 35-50 years]) had a median PDD of 14% (interquartile range, 0%-48%). During follow-up, 10 361 of 55 040 scheduled visits (18.8%) were missed, 6191 of 28 455 viral loads (21.8%) were detectable, and the mortality rate was 1.5 deaths per 100 person-years. Percentage of days with depression showed a dose-response relationship with each outcome. Each 25% increase in PDD led to an 8% increase in the risk of missing a scheduled appointment (risk ratio, 1.08; 95% CI, 1.05-1.11), a 5% increase in the risk of a detectable viral load (risk ratio, 1.05; 95% CI, 1.01-1.09), and a 19% increase in the mortality hazard (hazard ratio, 1.19; 95% CI, 1.05-1.36). These estimates imply that, compared with patients who spent no follow-up time with depression (PDD, 0%), those who spent the entire follow-up time with depression (PDD, 100%) faced a 37% increased risk of missing appointments (risk ratio, 1.37; 95% CI, 1.22-1.53), a 23% increased risk of a detectable viral load (risk ratio, 1.23; 95% CI, 1.06-1.43), and a doubled mortality rate (hazard ratio, 2.02; 95% CI, 1.20-3.42). Conclusions and Relevance: Greater chronicity of depression increased the likelihood of failure at multiple points along the HIV care continuum. Even modest increases in the proportion of time spent with depression led to clinically meaningful increases in negative outcomes. Clinic-level trials of protocols to promptly identify and appropriately treat depression among adults living with HIV should be conducted to understand the effect of such protocols on shortening the course and preventing the recurrence of depressive illness and improving clinical outcomes. PMID- 29466532 TI - Association of Hippocampal Atrophy With Duration of Untreated Psychosis and Molecular Biomarkers During Initial Antipsychotic Treatment of First-Episode Psychosis. AB - Importance: Duration of untreated psychosis (DUP) has been associated with poor outcomes in schizophrenia, but the mechanism responsible for this association is not known. Objectives: To determine whether hippocampal volume loss occurs during the initial 8 weeks of antipsychotic treatment and whether it is associated with DUP, and to examine molecular biomarkers in association with hippocampal volume loss and DUP. Design, Setting, and Participants: A naturalistic longitudinal study with matched healthy controls was conducted at Shanghai Mental Health Center. Between March 5, 2013, and October 8, 2014, 71 medication-naive individuals with nonaffective first-episode psychosis (FEP) and 73 age- and sex matched healthy controls were recruited. After approximately 8 weeks, 31 participants with FEP and 32 controls were reassessed. Exposures: The participants with FEP were treated according to standard clinical practice with second-generation antipsychotics. Main Outcomes and Measures: Hippocampal volumetric integrity (HVI) (an automated estimate of the parenchymal fraction in a standardized hippocampal volume of interest), DUP, 13 peripheral molecular biomarkers, and 14 single-nucleotide polymorphisms from 12 candidate genes were determined. Results: The full sample consisted of 71 individuals with FEP (39 women and 32 men; mean [SD] age, 25.2 [7.7] years) and 73 healthy controls (40 women and 33 men; mean [SD] age, 23.9 [6.4] years). Baseline median left HVI was lower in the FEP group (n = 57) compared with the controls (n = 54) (0.9275 vs 0.9512; difference in point estimate, -0.020 [95% CI, -0.029 to -0.010]; P = .001). During approximately 8 weeks of antipsychotic treatment, left HVI decreased in 24 participants with FEP at a median annualized rate of -.03791 ( 4.1% annualized change from baseline) compared with an increase of 0.00115 (0.13% annualized change from baseline) in 31 controls (difference in point estimate, 0.0424 [95% CI, -0.0707 to -0.0164]; P = .001). The change in left HVI was inversely associated with DUP (r = -0.61; P = .002). Similar results were found for right HVI, although the association between change in right HVI and DUP did not achieve statistical significance (r = -0.35; P = .10). Exploratory analyses restricted to the left HVI revealed an association between left HVI and markers of inflammation, oxidative stress, brain-derived neurotrophic factor, glial injury, and markers reflecting dopaminergic and glutamatergic transmission. Conclusions and Relevance: An association between longer DUP and accelerated hippocampal atrophy during initial treatment suggests that psychosis may have persistent, possibly deleterious, effects on brain structure. Additional studies are needed to replicate these exploratory findings of molecular mechanisms by which untreated psychosis may affect hippocampal volume and to determine whether these effects account for the known association between longer DUP and poor outcome.

PMID- 29466533 TI - Effectiveness of the DECIDE Interventions on Shared Decision Making and Perceived Quality of Care in Behavioral Health With Multicultural Patients: A Randomized Clinical Trial. AB - Importance: Few randomized clinical trials have been conducted with ethnic/racial minorities to improve shared decision making (SDM) and quality of care. Objective: To test the effectiveness of patient and clinician interventions to improve SDM and quality of care among an ethnically/racially diverse sample. Design, Setting, and Participants: This cross-level 2 * 2 randomized clinical trial included clinicians at level 2 and patients (nested within clinicians) at level 1 from 13 Massachusetts behavioral health clinics. Clinicians and patients were randomly selected at each site in a 1:1 ratio for each 2-person block. Clinicians were recruited starting September 1, 2013; patients, starting November 3, 2013. Final data were collected on September 30, 2016. Data were analyzed based on intention to treat. Interventions: The clinician intervention consisted of a workshop and as many as 6 coaching telephone calls to promote communication and therapeutic alliance to improve SDM. The 3-session patient intervention sought to improve SDM and quality of care. Main Outcomes and Measures: The SDM was assessed by a blinded coder based on clinical recordings, patient perception of SDM and quality of care, and clinician perception of SDM. Results: Of 312 randomized patients, 212 (67.9%) were female and 100 (32.1%) were male; mean (SD) age was 44.0 (15.0) years. Of 74 randomized clinicians, 56 (75.7%) were female and 18 (4.3%) were male; mean (SD) age was 39.8 (12.5) years. Patient-clinician pairs were assigned to 1 of the following 4 design arms: patient and clinician in the control condition (n = 72), patient in intervention and clinician in the control condition (n = 68), patient in the control condition and clinician in intervention (n = 83), or patient and clinician in intervention (n = 89). All pairs underwent analysis. The clinician intervention significantly increased SDM as rated by blinded coders using the 12-item Observing Patient Involvement in Shared Decision Making instrument (b = 4.52; SE = 2.17; P = .04; Cohen d = 0.29) but not as assessed by clinician or patient. More clinician coaching sessions (dosage) were significantly associated with increased SDM as rated by blinded coders (b = 12.01; SE = 3.72; P = .001; Cohen d = 0.78). The patient intervention significantly increased patient-perceived quality of care (b = 2.27; SE = 1.16; P = .05; Cohen d = 0.19). There was a significant interaction between patient and clinician dosage (b = 7.40; SE = 3.56; P = .04; Cohen d = 0.62), with the greatest benefit when both obtained the recommended dosage. Conclusions and Relevance: The clinician intervention could improve SDM with minority populations, and the patient intervention could augment patient-reported quality of care.

PMID- 29466536 TI - Association of Time to Attrition in Surgical Residency With Individual Resident and Programmatic Factors. AB - Importance: Attrition in general surgery residency remains high, and attrition that occurs in the later years is the most worrisome. Although several studies have retrospectively investigated the timing of attrition, no study to date has prospectively evaluated a national cohort of residents to understand which residents are at risk for attrition and at what point during residency. Objective: To prospectively evaluate individual resident and programmatic factors associated with the timing of attrition during general surgery residency. Design, Setting, and Participants: This longitudinal, national cohort study administered a survey to all categorical general surgery interns from the class of 2007-2008 during their first 30 days of residency and linked the data with 9-year follow-up data assessing program completion. Data were collected from June 1, 2007, through June 30, 2016. Main Outcomes and Measures: Kaplan-Meier curves evaluating time to attrition during the 9 years after the start of residency. Results: Among our sample of 836 residents (306 women [36.6%] and 528 men [63.2%]; gender unknown in 2), cumulative survival analysis demonstrated overall attrition for the cohort of 20.8% (n = 164). Attrition was highest in the first postgraduate year (67.6% [n = 111]; absolute rate, 13.3%) but continued during the next 6 years, albeit at a lower rate. Beginning in the first year, survival analysis demonstrated higher attrition among Hispanic compared with non-Hispanic residents (21.1% vs 12.4%; P = .04) and at military programs compared with academic or community programs after year 1 (32.3% vs 11.0% or 13.5%; P = .01). Beginning in year 4 of residency, higher attrition was encountered among women compared with men (23.3% vs 17.4%; P = .05); at year 5, at large compared with small programs (26.0% vs 18.4%; P = .04). Race and program location were not associated with attrition. Conclusions and Relevance: Although attrition was highest during the internship year, late attrition persists, particularly among women and among residents in large programs. These results provide a framework for timing of interventions in graduate surgical training that target residents most at risk for late attrition. PMID- 29466535 TI - Cross-Linguistic Cognate Production in Spanish-English Bilingual Children With and Without Specific Language Impairment. AB - Purpose: Bilinguals tend to produce cognates (e.g., telephone in English and telefono in Spanish) more accurately than they produce noncognates (table/mesa). We tested whether the same holds for bilingual children with specific language impairment (SLI). Method: Participants included Spanish-English bilingual children (aged 5;0 to 9;11 [years;months]), 25 with SLI and 92 without, who had comparable language experience. Cognate and noncognate items were taken from English and Spanish versions of the Expressive One-Word Picture Vocabulary Test (Brownell, 2000, 2001). Results: Although bilingual children with language impairment named fewer items correctly overall, they accurately named cognates more often than noncognates, as did typically developing children. Independent of language ability, accurate naming of a cognate in one language strongly predicted accurate naming in the other language. Conclusion: Language impairment appears unrelated to the mechanism that produces a cognate advantage in naming accuracy. Given that correct performance for a difficult word in one language is associated with knowing its cognate in another, cognates may be particularly viable targets for language intervention in bilingual children with SLI.

PMID- 29466539 TI - Management of Recurrent Vestibular Neuritis in a Patient Treated for Rheumatoid Arthritis. AB - Purpose: This clinical report is presented to describe how results of vestibular function testing were considered along with other medical history to develop a management plan that was ultimately successful. Method: The patient underwent audio-vestibular assessment including comprehensive audiogram, videonystagmography, cervical vestibular evoked myogenic potential, and postural stability testing. Results: Results from initial testing were most consistent with uncompensated peripheral vestibular dysfunction affecting the right superior vestibular nerve. These results, considered along with history and symptoms, supported vestibular neuritis. After a second vertigo event, we became concerned about the potential temporal association between the patient's rheumatoid arthritis treatment and symptom onset. It is established that treatment for rheumatoid arthritis can exacerbate latent viral issues, but this has not specifically been reported for vestibular neuritis. There are reports in the literature in which patients successfully used viral suppressant medication to decrease viral activity while they were able to continue benefiting from immunosuppressive therapy. We hypothesized that, if the current patient's vestibular neuritis events were related to her treatment for rheumatoid arthritis, she may also benefit from use of viral suppressant medication while continuing her otherwise successful immunosuppressive intervention. Conclusions: Patients treated with biologic disease-modifying antirheumatic drugs are more susceptible to viral issues, and this may include vestibular neuritis. For the current case, identifying this possibility and recommending viral suppressant medication allowed her to continue with successful treatment of rheumatoid arthritis while avoiding additional vertigo events.

AB - Importance: The accuracy of melanoma-specific dermoscopic criteria has been tested mainly in studies including invasive tumors. Scarce evidence exists on the usefulness of these criteria for the diagnosis of melanoma in situ (MIS). Objective: To investigate the diagnostic accuracy of dermoscopic criteria for the diagnosis of MIS. Design, Setting, and Participants: A diagnostic accuracy study with retrospective patient enrollment was conducted in 3 centers specializing in skin cancer diagnosis and management. A total of 1285 individuals with histopathologically diagnosed MIS or other flat, pigmented skin tumors that were histopathologically diagnosed or monitored for at least 1 year were included. Dermoscopic images of MIS and other flat, pigmented skin tumors were evaluated by 3 independent investigators for the presence of predefined criteria. Evaluators were blinded to the clinic dermoscopic and histopathologic diagnosis. Main Outcomes and Measures: Frequencies of dermoscopic criteria per diagnosis were calculated. Crude odds ratios, adjusted odds ratios, and corresponding 95% CIs were calculated by univariate and multivariate logistic regression, respectively. Results: A total of 1285 patients were included in the study (642 [50%] male); mean age was 45.9 years (range, 9-91 years). Of a total of 1285 lesions obtained from these patients, 325 (25.3%) were MIS; 574 (44.7%) were nevi (312 [24.3%] excised and 262 [20.4%] not excised); 67 (5.2%) were seborrheic keratoses, solar lentigines, or lichen planus-like keratoses; 91 (7.1%) were pigmented superficial basal cell carcinomas; 26 (2.0%) were pigmented intraepithelial carcinomas; 100 (7.8%) were Reed nevi; and 102 (7.9%) were invasive melanomas with a Breslow thickness less than 0.75 mm. The most frequent dermoscopic criteria for MIS were regression (302 [92.9%]), atypical network (278 [85.5%]), and irregular dots and/or globules (163 [50.2%]). The multivariate analysis revealed 5 main positive dermoscopic indicators of MIS: atypical network (3.7-fold; 95% CI, 2.5-5.4), regression (4.7-fold; 95% CI, 2.8-8.1), irregular hyperpigmented areas (5.4-fold; 95% CI, 3.7-8.0), prominent skin markings (3.4-fold; 95% CI, 1.9-6.1), and angulated lines (2.2-fold; 95% CI, 1.2-4.1). When compared only with excised nevi, 2 of these criteria remained potent MIS indicators, namely, irregular hyperpigmented areas (4.3-fold; 95% CI, 2.7-6.8) and prominent skin markings (2.7 fold; 95% CI, 1.3-5.7). Conclusions and Relevance: Clinicians should take into consideration the aforementioned dermoscopic indicators for the diagnosis of MIS. PMID- 29466543 TI - Ventricular Fibrillation.

(2017), 'How to Choose Between Measures of Tinnitus Loudness for Clinical Research? A Report on the Reliability and Validity of an Investigator-Administered Test and a Patient Reported Measure Using Baseline Data Collected in a Phase IIa Drug Trial'". AB - Purpose: The authors respond to a letter to the editor (Sabour, 2018) concerning the interpretation of validity in the context of evaluating treatment-related change in tinnitus loudness over time. Method: The authors refer to several landmark methodological publications and an international standard concerning the validity of patient-reported outcome measurement instruments. Results: The tinnitus loudness rating performed better against our reported acceptability criteria for (face and convergent) validity than did the tinnitus loudness matching test. Conclusion: It is important to distinguish between tests that evaluate the validity of measuring treatment-related change over time and tests that quantify the accuracy of diagnosing tinnitus as a case and non-case. PMID- 29466546 TI - Association of Hidradenitis Suppurativa With Body Image. AB - Importance: Hidradenitis suppurativa (HS) leads to disfigurement and painful eruptions in terminal hair follicles of the intertriginous skin, mainly of axillary, genitofemoral, and perianal sites. It is associated with an excessive impairment of quality of life, psychiatric disorders, and sexual distress. Body image impairment has been linked to depression and anxiety and has been described for some dermatologic disorders but has not yet been investigated in patients with HS. Objectives: To investigate whether body image is diminished in patients with HS and whether disease severity, age at onset, disease duration, obesity, depression, and anxiety are linked to body image impairment. Design, Setting, and Participants: This 12-month (August 1, 2009, to August 31, 2010) case-control study with a prospective, observational, cross-sectional design recruited 47 consecutive patients with HS entering a tertiary care center and 45 healthy control individuals matched for age, sex, and body mass index (BMI). One patient and 4 controls failed to complete the questionnaire and were excluded from the evaluation. Data analysis was performed from December 1, 2013, to February 15, 2014. Main Outcomes and Measures: The Frankfurt Body Concept Scale (FKKS) and the Hospital Anxiety and Depression Scale (HADS) were given to patients and controls. Correlations among FKKS, HADS, and disease features were calculated. Results: Of the 46 patients and 41 controls included in the evaluation (mean [SD] age, 35.6 [1.6] years; 40 [46%] male and 47 [54%] female), HS significantly reduced body image (mean FKKS score, 234.2 [5.4] in patients and 276.9 [5.7] in controls; P < .001), even when controlled for BMI. A correlation was found for the extent of body image disruption and BMI (r = -0.589; P < .001), HADS-depression score (r = 0.619; P < .001), and HADS-anxiety score (r = -0.340; P = .03). No association was found for the body image score and the severity of HS, age at onset of disease, and duration of disease. The body contact subscale score was the only subscale score that was not different between patients with HS and controls. Conclusions and Relevance: Patients with HS have major body image impairment, which might lead to depression and anxiety, disorders that have been largely acknowledged in HS. This study identified another element of the psychosocial burden of patients with HS and reveals that body image could potentially be used as an outcome measure in future studies of HS.

PMID- 29466549 TI - An International Survey of Assessment Practices for Short-Term and Working Memory Deficits in Aphasia. AB - Purpose: Recent research has highlighted the clinical relevance of understanding the nature of short-term memory (STM) and working memory (WM) deficits in persons with aphasia and the way these deficits affect linguistic processing and functional communication in activities of daily living. The psychometric properties of tests commonly used to identify STM/WM problems in individuals with aphasia, however, have been questioned. No previous study has sought to investigate assessment practices and attitudes by speech-language pathologists involved in aphasia management. Accordingly, the aims of this study were (a) to investigate both attitudes toward STM/WM assessment in individuals with aphasia, as well as the types and frequency of STM/WM tests used with individuals with aphasia, and (b) to explore factors (e.g., educational background) that may influence STM/WM assessment practices. Method: Respondents recruited via professional and aphasia support organizations completed an online survey. The survey elicited information about the respondents' demographic and clinical backgrounds and STM/WM assessment clinical practices and views, including frequency and preferred use of specific STM/WM tests. Results: The majority of respondents reported regular use of STM/WM tests as part of aphasia management. Positive attitudes toward STM/WM assessments were also reported. The most popular rankings of tests were the Cognitive Linguistic Quick Test (Helm-Estabrooks, 2001), the Comprehensive Aphasia Test (Swinburn, Porter, & Howard, 2005), and the Token Test (McNeil & Prescott, 1978). Results suggested limited knowledge about measures that assess self-perceptions of functional memory abilities. Regression analyses showed that the frequency of reported STM/WM test use was similar between clinicians and dual-role researchers/clinicians, but their attitudes toward the value of STM/WM differed. U.S. and UK respondents reported similar assessment practices. Conclusions: It is reassuring that STM/WM is taken into consideration by clinicians when providing aphasia management. Two of the most popular tests, however, have poor psychometric properties, and caution should be exercised in clinical decision making. The different value placed on STM/WM testing by clinicians and researchers/clinicians has implications for continuing professional development. PMID- 29466550 TI - Treatment of Phonological Disorder: A Feasibility Study With Focus on Outcome Measures. AB - Purpose: In a feasibility study for a randomized controlled trial of treatments for phonological disorders conducted over a period of 8 months, we examined 6 clinically relevant outcome measures. We took steps to reduce error variance and to maximize systematic variance. Method: Six children received traditional treatment (Van Riper, 1939), and 7 received expansion points (Smit, 2000), a treatment program with both phonological and traditional elements. Outcome measures, which were applied to both word list and conversational samples, included percentage of consonants correct (PCC; Shriberg & Kwiatkowski, 1982), PCC for late and/or difficult (L/D) consonants and number of L/D consonants acquired. Results: In repeated-measures analyses of variance, all measures showed significant differences from pretreatment to posttreatment, and the word list measures were associated with very high power values. In analyses of covariance for between-groups contrasts, the adjusted expansion points mean exceeded the adjusted traditional treatment mean for every measure; however, no differences reached significance. For the L/D PCC (conversation) measure, the contrast between groups was associated with a large effect size. Conclusion: We recommend that practitioners use outcome measures related to a word list. We recommend that researchers consider using L/D PCC on the basis of conversational samples to detect differences among treatment groups.

PMID- 29466552 TI - Statistical Methodology for the Analysis of Repeated Duration Data in Behavioral Studies. AB - Purpose: Repeated duration data are frequently used in behavioral studies. Classical linear or log-linear mixed models are often inadequate to analyze such data, because they usually consist of nonnegative and skew-distributed variables. Therefore, we recommend use of a statistical methodology specific to duration data. Method: We propose a methodology based on Cox mixed models and written under the R language. This semiparametric model is indeed flexible enough to fit duration data. To compare log-linear and Cox mixed models in terms of goodness-of fit on real data sets, we also provide a procedure based on simulations and quantile-quantile plots. Results: We present two examples from a data set of speech and gesture interactions, which illustrate the limitations of linear and log-linear mixed models, as compared to Cox models. The linear models are not validated on our data, whereas Cox models are. Moreover, in the second example, the Cox model exhibits a significant effect that the linear model does not. Conclusions: We provide methods to select the best-fitting models for repeated duration data and to compare statistical methodologies. In this study, we show that Cox models are best suited to the analysis of our data set. PMID- 29466553 TI - The Effects of Varying Directional Bandwidth in Hearing Aid Users' Preference and Speech-in-Noise Performance. AB - Purpose: Directional microphone systems are typically used to improve hearing aid users' understanding of speech in noise. However, directional microphones also increase internal hearing aid noise. The purpose of this study was to investigate how varying directional microphone bandwidth affected listening preference and speech-in-noise performance. Method: Ten participants with normal hearing and 10 participants with hearing impairment compared internal noise levels between hearing aid memories with 4 different microphone modes: omnidirectional, full directional, high-frequency directionality with directional processing above 900 Hz, and high-frequency directionality with directional processing above 2000 Hz. Speech-in-noise performance was measured with each memory for the participants with hearing impairment. Results: Participants with normal hearing preferred memories with less directional bandwidth. Participants with hearing impairment also tended to prefer the memories with less directional bandwidth. However, the majority of participants with hearing impairment did not indicate a preference between omnidirectional and directional above 2000 Hz memories. Average hearing in-noise performance improved with increasing directional bandwidth. Conclusions: Most participants preferred memories with less directional bandwidth in quiet. Participants with hearing impairment indicated no difference in preference between directional above 2000 Hz and the omnidirectional memories. Speech recognition in noise performance improved with increasing directional bandwidth. PMID- 29466554 TI - Trenchlike Ulcer on a Newborn's Scalp. PMID- 29466555 TI - Pitch and Time Processing in Speech and Tones: The Effects of Musical Training and Attention. AB - Purpose: Musical training is often linked to enhanced auditory discrimination, but the relative roles of pitch and time in music and speech are unclear. Moreover, it is unclear whether pitch and time processing are correlated across individuals and how they may be affected by attention. This study aimed to examine pitch and time processing in speech and tone sequences, taking musical training and attention into account. Method: Musicians (16) and nonmusicians (16) were asked to detect pitch or timing changes in speech and tone sequences and make a binary response. In some conditions, the participants were focused on 1 aspect of the stimulus (directed attention), and in others, they had to pay attention to all aspects at once (divided attention). Results: As expected, musicians performed better overall. Performance scores on pitch and time tasks were correlated, as were performance scores for speech and tonal stimuli, but most markedly in musicians. All participants performed better on the directed versus divided attention task, but again, musicians performed better than nonmusicians. Conclusion: In general, this experiment shows that individuals with a better sense of pitch discrimination also have a better sense of timing discrimination in the auditory domain. In addition, although musicians perform better overall, these results do not support the idea that musicians have an added advantage for divided attention tasks. These findings serve to better understand how musical training and attention affect pitch and time processing in the context of speech and tones and may have applications in special populations.

AB - Purpose: The objectives of this study were to identify acoustic characteristics of connected speech that differentiate children with dysarthria secondary to cerebral palsy (CP) from typically developing children and to identify acoustic measures that best detect dysarthria in children with CP. Method: Twenty 5-year old children with dysarthria secondary to CP were compared to 20 age- and sex matched typically developing children on 5 acoustic measures of connected speech. A logistic regression approach was used to derive an acoustic model that best predicted dysarthria status. Results: Results indicated that children with dysarthria secondary to CP differed from typically developing children on measures of multiple segmental and suprasegmental speech characteristics. An acoustic model containing articulation rate and the F2 range of diphthongs differentiated children with dysarthria from typically developing children with 87.5% accuracy. Conclusion: This study serves as a first step toward developing an acoustic model that can be used to improve early identification of dysarthria in children with CP. PMID- 29466557 TI - Bilingualism and Procedural Learning in Typically Developing Children and Children With Language Impairment. AB - Purpose: The aim of this study was to investigate whether dual language experience affects procedural learning ability in typically developing children and in children with specific language impairment (SLI). Method: We examined procedural learning in monolingual and bilingual school-aged children (ages 8-12 years) with and without SLI. The typically developing children (35 monolinguals, 24 bilinguals) and the children with SLI (17 monolinguals, 10 bilinguals) completed a serial reaction time task. Results: The typically developing monolinguals and bilinguals exhibited equivalent sequential learning effects, but neither group with SLI exhibited learning of sequential patterns on the serial reaction time task. Conclusion: Procedural learning does not appear to be modified by language experience, supporting the notion that it is a child intrinsic language learning mechanism that is minimally malleable to experience. PMID- 29466558 TI - In-Hospital ST-Segment Elevation Myocardial Infarction: Improving Diagnosis, Triage, and Treatment. AB - Importance: In-hospital ST-segment elevation myocardial infarction (STEMI) is a unique clinical entity with epidemiology, incidence, and outcomes distinct from that of out-of-hospital STEMI and has only within the past 10 years begun to receive increased attention and research. Patients with in-hospital STEMI are older, have more comorbidities, and more frequently have coagulopathies and contraindications for anticoagulation and fibrinolytic therapy. A standardized clinical definition of in-hospital STEMI is lacking. The objectives of this special communication are to (1) summarize the knowledge base regarding in hospital STEMI; (2) review the challenges of diagnosis and treatment of patients with in-hospital STEMI; (3) present a standardized clinical definition for in hospital STEMI; and (4) provide a quality improvement protocol to improve diagnosis, triage, and treatment of patients with in-hospital STEMI. Observations: Patients with in-hospital STEMI less frequently present with typical angina symptoms, and an electrocardiogram is often obtained owing to changes in clinical status, changes on telemetry, or a finding of elevated cardiac biomarker. The frequent nontypical presentations often lead to substantial delays in the diagnosis of STEMI. Only 34% to 71% of patients with in hospital STEMI undergo diagnostic catheterization, and only 22% to 56% undergo percutaneous coronary intervention. Even in contemporary reports, some studies report in-hospital mortality in the range of 31% to 42%. Three areas of delay in the treatment of patients with in-hospital STEMI that merit particular attention are (1) delays in electrocardiogram acquisition, (2) delays in electrocardiogram interpretation, and (3) delays in activation of existing STEMI systems of care. Conclusions and Relevance: Treatment of patients with in-hospital STEMI is more complex and challenging than treatment of patients who develop out-of-hospital STEMI, leading to delays in diagnosis and triage and less frequent use of reperfusion therapy. Quality improvement programs targeted at decreasing delays and streamlining treatment of such patients may improve treatment and outcome. PMID- 29466559 TI - Association of Faculty Entrustment With Resident Autonomy in the Operating Room. AB - Importance: A critical balance is sought between faculty supervision, appropriate resident autonomy, and patient safety in the operating room. Variability in the release of supervision during surgery represents a potential safety hazard to patients. A better understanding of intraoperative faculty-resident interactions is needed to determine what factors influence entrustment. Objective: To assess faculty and resident intraoperative entrustment behaviors and to determine whether faculty behaviors drive resident entrustability in the operating room. Design, Setting, and Participants: This observational study was conducted from September 1, 2015, to August 31, 2016, at Michigan Medicine, the University of Michigan's health care system. Two surgical residents, 1 medical student, 2 behavioral research scientists, and 1 surgical faculty member observed surgical intraoperative interactions between faculty and residents in 117 cases involving 28 faculty and 35 residents and rated entrustment behaviors. Without intervening in the interaction, 1 or 2 researchers observed each case and noted behaviors, verbal and nonverbal communication, and interaction processes. Immediately after the case, observers completed an assessment using OpTrust, a validated tool designed to assess progressive entrustment in the operating room. Purposeful sampling was used to generate variation in type of operation, case difficulty, faculty-resident pairings, faculty experience, and resident training level. Main Outcomes and Measures: Observer results in the form of entrustability scores (range, 1-4, with 4 indicating full entrustability) were compared with resident- and faculty-reported measures. Difficulty of operation was rated on a scale of 1 to 3 (higher scores indicate greater difficulty). Path analysis was used to explore direct and indirect effects of the predictors. Associations between resident entrustability and observation duration, observation month, and faculty entrustment scores were assessed by pairwise Pearson correlation coefficients. Results: Twenty-eight faculty and 35 residents were observed across 117 surgical cases from 4 surgical specialties. Cases observed by postgraduate year (PGY) of residents were distributed as follows: PGY-1, 21 (18%); 2, 15 (13%); 3, 17 (15%); 4, 27 (23%); 5, 28 (24%); and 6, 9 (8%). Case difficulty was evenly distributed: 36 (33%) were rated easy/straightforward; 43 (40%), moderately difficult; and 29 (27%), very difficult by attending physicians. Path analysis showed that the association of PGY with resident entrustability was mediated by faculty entrustment (0.23 [.03]; P < .001). At the univariate level, case difficulty (mean [SD] resident entrustability score range, 1.97 [0.75] for easy/straightforward cases to 2.59 [0.82] for very difficult cases; F = 6.69; P = .01), PGY (range, 1.31 [0.28] for PGY-1 to 3.16 [0.54] for PGY-6; F = 22.85; P < .001), and faculty entrustment (2.27 [0.79]; R2 = 0.91; P < .001) were significantly associated with resident entrustability. Mean (SD) resident entrustability scores were highest for very difficult cases (2.59 [0.82]) and PGY 6 (3.16 [0.54]). Conclusions and Relevance: Faculty entrustment behaviors may be the primary drivers of resident entrustability. Faculty entrustment is a feature of faculty surgeons' teaching style and could be amenable to faculty development efforts. PMID- 29466560 TI - Comparison of Military and Civilian Methods for Determining Potentially Preventable Deaths: A Systematic Review. AB - Importance: Military and civilian trauma experts initiated a collaborative effort to develop an integrated learning trauma system to reduce preventable morbidity and mortality. Because the Department of Defense does not currently have recommended guidelines and standard operating procedures to perform military preventable death reviews in a consistent manner, these performance improvement processes must be developed. Objectives: To compare military and civilian preventable death determination methods to understand the existing best practices for evaluating preventable death. Evidence Review: This systematic review followed the PRISMA reporting guidelines. English-language articles were searched from inception to February 15, 2017, using the following databases: MEDLINE (Ovid), Evidence-Based Medicine Reviews (Ovid), PubMed, CINAHL, and Google Scholar. Articles were initially screened for eligibility and excluded based on predetermined criteria. Articles reviewing only prehospital deaths, only inhospital deaths, or both were eligible for inclusion. Information on study characteristics was independently abstracted by 2 investigators. Reported are methodological factors affecting the reliability of preventable death studies and the preventable death rate, defined as the number of potentially preventable deaths divided by the total number of deaths within a specific patient population. Findings: Fifty studies (8 military and 42 civilian) met the inclusion criteria. In total, 1598 of 6500 military deaths reviewed and 3346 of 19 108 civilian deaths reviewed were classified as potentially preventable. Among military studies, the preventable death rate ranged from 3.1% to 51.4%. Among civilian studies, the preventable death rate ranged from 2.5% to 85.3%. The high level of methodological heterogeneity regarding factors, such as preventable death definitions, review process, and determination criteria, hinders a meaningful quantitative comparison of preventable death rates. Conclusions and Relevance: The reliability of military and civilian preventable death studies is hindered by inconsistent definitions, incompatible criteria, and the overall heterogeneity in study methods. The complexity, inconsistency, and unpredictability of combat require unique considerations to perform a methodologically sound combat-related preventable death review. As the Department of Defense begins the process of developing recommended guidelines and standard operating procedures for performing military preventable death reviews, consideration must be given to the factors known to increase the risk of bias and poor reliability. PMID- 29466561 TI - Comment on Hall et al. (2017), "How to Choose Between Measures of Tinnitus Loudness for Clinical Research? A Report on the Reliability and Validity of an Investigator-Administered Test and a Patient-Reported Measure Using Baseline Data Collected in a Phase IIa Drug Trial". AB - Purpose: The purpose of this letter, in response to Hall, Mehta, and Fackrell (2017), is to provide important knowledge about methodology and statistical issues in assessing the reliability and validity of an audiologist-administered tinnitus loudness matching test and a patient-reported tinnitus loudness rating. Method: The author uses reference textbooks and published articles regarding scientific assessment of the validity and reliability of a clinical test to discuss the statistical test and the methodological approach in assessing validity and reliability in clinical research. Results: Depending on the type of the variable (qualitative or quantitative), well-known statistical tests can be applied to assess reliability and validity. The qualitative variables of sensitivity, specificity, positive predictive value, negative predictive value, false positive and false negative rates, likelihood ratio positive and likelihood ratio negative, as well as odds ratio (i.e., ratio of true to false results), are the most appropriate estimates to evaluate validity of a test compared to a gold standard. In the case of quantitative variables, depending on distribution of the variable, Pearson r or Spearman rho can be applied. Conclusion: Diagnostic accuracy (validity) and diagnostic precision (reliability or agreement) are two completely different methodological issues. Depending on the type of the variable (qualitative or quantitative), well-known statistical tests can be applied to assess validity. PMID- 29466564 TI - Validation of the Chinese Sound Test: Auditory Performance of Hearing Aid Users. AB - Purpose: The Chinese Sound Test (Hung, Lin, Tsai, & Lee, 2016) has been recently developed as a modified version of the Ling Six-Sound Test (Ling, 2012). By incorporating Chinese speech sounds, this test should be able to estimate whether the listener can hear across the Chinese speech spectrum. To establish the clinical validity of the test, this study examined the relationship between the aided audiometric thresholds and the distance thresholds. Method: Sixty children with bilateral hearing aids were recruited. The aided sound-field thresholds at 250, 500, 1000, 2000, 4000, and 6000 Hz were compared with the distance thresholds of six sounds, /u, e, a, i, tch, and s/, which encompass the entire Chinese speech frequency range from low to high. Results: Partial correlation and stepwise regression analyses revealed that the Chinese testing sounds are frequency specific and that the audibility of each sound could be predicted by a specific frequency threshold. Conclusions: The results confirm the validity of the Chinese Sound Test, indicating that the testing sounds can be reliably used to assess the perception of frequency-specific information. Crucially, these data also demonstrate that the Chinese Sound Test is a useful tool to identify red flags of poor auditory access in daily environment to monitor device malfunctions and possible hearing fluctuations.

PMID- 29466590 TI - Administrative Costs Associated With Physician Billing and Insurance-Related Activities at an Academic Health Care System. AB - Importance: Administrative costs in the US health care system are an important component of total health care spending, and a substantial proportion of these costs are attributable to billing and insurance-related activities. Objective: To examine and estimate the administrative costs associated with physician billing activities in a large academic health care system with a certified electronic health record system. Design, Setting, and Participants: This study used time driven activity-based costing. Interviews were conducted with 27 health system administrators and 34 physicians in 2016 and 2017 to construct a process map charting the path of an insurance claim through the revenue cycle management process. These data were used to calculate the cost for each major billing and insurance-related activity and were aggregated to estimate the health system's total cost of processing an insurance claim. Exposures: Estimated time required to perform billing and insurance-related activities, based on interviews with management personnel and physicians. Main Outcomes and Measures: Estimated billing and insurance-related costs for 5 types of patient encounters: primary care visits, discharged emergency department visits, general medicine inpatient stays, ambulatory surgical procedures, and inpatient surgical procedures. Results: Estimated processing time and total costs for billing and insurance related activities were 13 minutes and $20.49 for a primary care visit, 32 minutes and $61.54 for a discharged emergency department visit, 73 minutes and $124.26 for a general inpatient stay, 75 minutes and $170.40 for an ambulatory surgical procedure, and 100 minutes and $215.10 for an inpatient surgical procedure. Of these totals, time and costs for activities carried out by physicians were estimated at a median of 3 minutes or $6.36 for a primary care visit, 3 minutes or $10.97 for an emergency department visit, 5 minutes or $13.29 for a general inpatient stay, 15 minutes or $51.20 for an ambulatory surgical procedure, and 15 minutes or $51.20 for an inpatient surgical procedure. Of professional revenue, professional billing costs were estimated to represent 14.5% for primary care visits, 25.2% for emergency department visits, 8.0% for general medicine inpatient stays, 13.4% for ambulatory surgical procedures, and 3.1% for inpatient surgical procedures. Conclusions and Relevance: In a time driven activity-based costing study in a large academic health care system with a certified electronic health record system, the estimated costs of billing and insurance-related activities ranged from $20 for a primary care visit to $215 for an inpatient surgical procedure. Knowledge of how specific billing and insurance related activities contribute to administrative costs may help inform policy solutions to reduce these expenses.

PMID- 29466591 TI - Effect of Haloperidol on Survival Among Critically Ill Adults With a High Risk of Delirium: The REDUCE Randomized Clinical Trial. AB - Importance: Results of studies on use of prophylactic haloperidol in critically ill adults are inconclusive, especially in patients at high risk of delirium. Objective: To determine whether prophylactic use of haloperidol improves survival among critically ill adults at high risk of delirium, which was defined as an anticipated intensive care unit (ICU) stay of at least 2 days. Design, Setting, and Participants: Randomized, double-blind, placebo-controlled investigator driven study involving 1789 critically ill adults treated at 21 ICUs, at which nonpharmacological interventions for delirium prevention are routinely used in the Netherlands. Patients without delirium whose expected ICU stay was at least a day were included. Recruitment was from July 2013 to December 2016 and follow-up was conducted at 90 days with the final follow-up on March 1, 2017. Interventions: Patients received prophylactic treatment 3 times daily intravenously either 1 mg (n = 350) or 2 mg (n = 732) of haloperidol or placebo (n = 707), consisting of 0.9% sodium chloride. Main Outcome and Measures: The primary outcome was the number of days that patients survived in 28 days. There were 15 secondary outcomes, including delirium incidence, 28-day delirium-free and coma-free days, duration of mechanical ventilation, and ICU and hospital length of stay. Results: All 1789 randomized patients (mean, age 66.6 years [SD, 12.6]; 1099 men [61.4%]) completed the study. The 1-mg haloperidol group was prematurely stopped because of futility. There was no difference in the median days patients survived in 28 days, 28 days in the 2-mg haloperidol group vs 28 days in the placebo group, for a difference of 0 days (95% CI, 0-0; P = .93) and a hazard ratio of 1.003 (95% CI, 0.78-1.30, P=.82). All of the 15 secondary outcomes were not statistically different. These included delirium incidence (mean difference, 1.5%, 95% CI, -3.6% to 6.7%), delirium-free and coma-free days (mean difference, 0 days, 95% CI, 0-0 days), and duration of mechanical ventilation, ICU, and hospital length of stay (mean difference, 0 days, 95% CI, 0 0 days for all 3 measures). The number of reported adverse effects did not differ between groups (2 [0.3%] for the 2-mg haloperidol group vs 1 [0.1%] for the placebo group). Conclusions and Relevance: Among critically ill adults at high risk of delirium, the use of prophylactic haloperidol compared with placebo did not improve survival at 28 days. These findings do not support the use of prophylactic haloperidol for reducing mortality in critically ill adults. Trial Registration: clinicaltrials.gov Identifier: NCT01785290. PMID- 29466592 TI - Effect of Low-Fat vs Low-Carbohydrate Diet on 12-Month Weight Loss in Overweight Adults and the Association With Genotype Pattern or Insulin Secretion: The DIETFITS Randomized Clinical Trial. AB - Importance: Dietary modification remains key to successful weight loss. Yet, no one dietary strategy is consistently superior to others for the general population. Previous research suggests genotype or insulin-glucose dynamics may modify the effects of diets. Objective: To determine the effect of a healthy low fat (HLF) diet vs a healthy low-carbohydrate (HLC) diet on weight change and if genotype pattern or insulin secretion are related to the dietary effects on weight loss. Design, Setting, and Participants: The Diet Intervention Examining The Factors Interacting with Treatment Success (DIETFITS) randomized clinical trial included 609 adults aged 18 to 50 years without diabetes with a body mass index between 28 and 40. The trial enrollment was from January 29, 2013, through April 14, 2015; the date of final follow-up was May 16, 2016. Participants were randomized to the 12-month HLF or HLC diet. The study also tested whether 3 single-nucleotide polymorphism multilocus genotype responsiveness patterns or insulin secretion (INS-30; blood concentration of insulin 30 minutes after a glucose challenge) were associated with weight loss. Interventions: Health educators delivered the behavior modification intervention to HLF (n = 305) and HLC (n = 304) participants via 22 diet-specific small group sessions administered over 12 months. The sessions focused on ways to achieve the lowest fat or carbohydrate intake that could be maintained long-term and emphasized diet quality. Main Outcomes and Measures: Primary outcome was 12-month weight change and determination of whether there were significant interactions among diet type and genotype pattern, diet and insulin secretion, and diet and weight loss. Results: Among 609 participants randomized (mean age, 40 [SD, 7] years; 57% women; mean body mass index, 33 [SD, 3]; 244 [40%] had a low-fat genotype; 180 [30%] had a low-carbohydrate genotype; mean baseline INS-30, 93 MUIU/mL), 481 (79%) completed the trial. In the HLF vs HLC diets, respectively, the mean 12 month macronutrient distributions were 48% vs 30% for carbohydrates, 29% vs 45% for fat, and 21% vs 23% for protein. Weight change at 12 months was -5.3 kg for the HLF diet vs -6.0 kg for the HLC diet (mean between-group difference, 0.7 kg [95% CI, -0.2 to 1.6 kg]). There was no significant diet-genotype pattern interaction (P = .20) or diet-insulin secretion (INS-30) interaction (P = .47) with 12-month weight loss. There were 18 adverse events or serious adverse events that were evenly distributed across the 2 diet groups. Conclusions and Relevance: In this 12-month weight loss diet study, there was no significant difference in weight change between a healthy low-fat diet vs a healthy low-carbohydrate diet, and neither genotype pattern nor baseline insulin secretion was associated with the dietary effects on weight loss. In the context of these 2 common weight loss diet approaches, neither of the 2 hypothesized predisposing factors was helpful in identifying which diet was better for whom. Trial Registration: clinicaltrials.gov Identifier: NCT01826591. PMID- 29466595 TI - A Teaching Case. PMID- 29466596 TI - Acute Respiratory Distress Syndrome: Advances in Diagnosis and Treatment. AB - Importance: Acute respiratory distress syndrome (ARDS) is a life-threatening form of respiratory failure that affects approximately 200 000 patients each year in the United States, resulting in nearly 75 000 deaths annually. Globally, ARDS accounts for 10% of intensive care unit admissions, representing more than 3 million patients with ARDS annually. Objective: To review advances in diagnosis and treatment of ARDS over the last 5 years. Evidence Review: We searched MEDLINE, EMBASE, and the Cochrane Database of Systematic Reviews from 2012 to 2017 focusing on randomized clinical trials, meta-analyses, systematic reviews, and clinical practice guidelines. Articles were identified for full text review with manual review of bibliographies generating additional references. Findings: After screening 1662 citations, 31 articles detailing major advances in the diagnosis or treatment of ARDS were selected. The Berlin definition proposed 3 categories of ARDS based on the severity of hypoxemia: mild (200 mm Hg=80 years who engaged in normal activities of daily living were the study cohort. WM function was evaluated by a simple visual WM test consisting of 3 figures. We considered the number of figures recalled by the patient his/her test score. We defined the patients with a score of 0 or 1 as those with WM impairment and those with scores of 2 or 3 as those without. To investigate the relative risk of WM impairment, we evaluated each patient's 24 hour ambulatory systolic blood pressure (SBP) and its weighted standard deviation (SDSBP ), office SBP, and the visit-to-visit SDSBP during the 1 year period from the patient's enrollment. A total of 66 patients (mean 84 +/- 3.6 years) showed WM impairment, and 431 patients (mean 83 +/- 3.1 years) showed no WM impairment. There were no significant differences in 24 hour ambulatory SBP or office SBP between these two groups. However, the WM impairment patients showed significantly higher weighted SDSBP and visit-to-visit SDSBP values compared to the no-impairment group even after adjusting for age. Among these >=80-year-old patients, those with the highest quartile of both weighted SDSBP (>=21.4 mm Hg) and visit-to-visit SDSBP (>=14.5 mm Hg) showed the highest relative risk (odds ratio 3.52, 95% confidence interval 1.42-8.72) for WM impairment. Exaggerated blood pressure variability parameters were significantly associated with working memory impairment in very elderly individuals. PMID- 29466611 TI - Roles of UVA radiation and DNA damage responses in melanoma pathogenesis. AB - The growing incidence of melanoma is a serious public health issue that merits a thorough understanding of potential causative risk factors, which includes exposure to ultraviolet radiation (UVR). Though UVR has been classified as a complete carcinogen and has long been recognized for its ability to damage genomic DNA through both direct and indirect means, the precise mechanisms by which the UVA and UVB components of UVR contribute to the pathogenesis of melanoma have not been clearly defined. In this review, we therefore highlight recent studies that have addressed roles for UVA radiation in the generation of DNA damage and in modulating the subsequent cellular responses to DNA damage in melanocytes, which are the cell type that gives rise to melanoma. Recent research suggests that UVA not only contributes to the direct formation of DNA lesions but also impairs the removal of UV photoproducts from genomic DNA through oxidation and damage to DNA repair proteins. Moreover, the melanocyte microenvironment within the epidermis of the skin is also expected to impact melanomagenesis, and we therefore discuss several paracrine signaling pathways that have been shown to impact the DNA damage response in UV-irradiated melanocytes. Lastly, we examine how alterations to the immune microenvironment by UVA-associated DNA damage responses may contribute to melanoma development. Thus, there appear to be multiple avenues by which UVA may elevate the risk of melanoma. Protective strategies against excess exposure to UVA wavelengths of light therefore have the potential to decrease the incidence of melanoma. Environ. Mol. Mutagen. 59:438 460, 2018.

AB - We developed a facile approach to the construction of bio-recognition sites in silica nanoparticles for efficient separation of bovine hemoglobin based on amino functionalized silica nanoparticles grafting by 3-aminopropyltriethoxylsilane providing hydrogen bonds with bovine hemoglobin through surface molecularly imprinting technology. The resulting amino-functionalized silica surface molecularly imprinted polymers were characterized using scanning electron microscope, transmission electronic microscopy, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and thermogravimetric analysis. Results showed that the as-synthesized imprinted polymers exhibited spherical morphology and favorable thermal stability. The binding adsorption experiments showed that the imprinted polymers can reach equilibrium within 1 h. The Langmuir isotherm and pseudo-second-order kinetic model fitted the adsorption data well. Meanwhile, the imprinted polymers possessed a maximum binding capacity up to 90.3 mg/g and highly selectivity for the recognition of bovine hemoglobin. Moreover, such high binding capacity and selectivity retained after eight cycles, indicating the good stability and reusability of the imprinted polymers. Finally, successful application in the selective recognition of bovine hemoglobin from a real bovine blood sample indicated that the imprinted polymers displayed great potentials in efficient purification and separation of target proteins. PMID- 29466620 TI - Secretome Analysis of Hypoxia-Induced 3T3-L1 Adipocytes Uncovers Novel Proteins Potentially Involved in Obesity. AB - In the obese state, as adipose tissue expands, adipocytes become hypoxic and dysfunctional, leading to changes in the pattern of adipocyte-secreted proteins. To better understand the role of hypoxia in the mechanisms linked to obesity, we comparatively analyzed the secretome of murine differentiated 3T3-L1 adipocytes exposed to normoxia or hypoxia for 24 h. Proteins secreted into the culture media were precipitated by trichloroacetic acid and then digested with trypsin. The peptides were labeled with dimethyl labeling and analyzed by reversed phase nanoscale liquid chromatography coupled to a quadrupole Orbitrap mass spectrometer. From a total of 1508 identified proteins, 109 were differentially regulated, of which 108 were genuinely secreted. Factors significantly downregulated in hypoxic conditions included adiponectin, a known adipokine implicated in metabolic processes, as well as thrombospondin-1 and -2, and matrix metalloproteinase-11, all multifunctional proteins involved in extracellular matrix (ECM) homeostasis. Findings were validated by Western blot analysis. Expression studies of the relative genes were performed in parallel experiments in vitro, in differentiated 3T3-L1 adipocytes, and in vivo, in fat tissues from obese versus lean mice. Our observations are compatible with the concept that hypoxia may be an early trigger for both adipose cell dysfunction and ECM remodeling. PMID- 29466621 TI - Assessment of Arabidopsis thaliana CENH3 promoter in Brassica juncea for development of haploid inducer lines. AB - Centromeres are epigenetically specified by the centromeric histone H3 protein (CENH3). The timing and level of expression of CENH3 is tightly regulated to match the demands of the host cell. So far in plants, only CENH3 promoter of Arabidopsis thaliana (L.) Heynh. has been characterized. However, whether CENH3 promoters retain their characteristic mode of regulation in other species remains to be established. In the present study, activity of AtCENH3 promoter was investigated using reporter gene assay in Brassica juncea (L.) Czem. A 1156 bp promoter fragment of AtCENH3 gene (At1g01370) including the first 111 nucleotides of the coding sequence was amplified and cloned into the pORE-R2 binary vector to ensure translation fusion with the uidA coding sequences. The Agrobacteriun tiunefaciens strain GV3101 harbouring the recombinant construct was used to transform B. juncea cv. RLM198 hypocotyl explants. Histochemical assay of To and T, transgenics showed GUS expression in shoot apical meristem, leaf, sepal, flower pedicel and root tip. Intense GUS expression was observed in meristematic tissues, particularly at shoot and root apices. However, mature leaves, flowers, pollen and ovules exhibited very low or no GUS expression. Our results showed that AtCENH3 promoter regulates cognate gene expression in Brassica juncea as it does in A. thaliana, and hence a suitable candidate for developing haploid inducer line in B. juncea. PMID- 29466622 TI - Isolation and characterization of Lepidoptera specific Bacillus thuringiensis strains predominantly from north-eastern states of India. AB - Both, the tobacco caterpillar Spodoptera litura (Fabricius) and the cotton bollworm Helicoverpa armigera (Hibner), are serious polyphagous pests causing considerable loss to crops. Indiscriminate use of chemical pesticides for controlling them has rather resulted in their resistance development. Microbial pesticides, Bacillus thuringiensis in particular, play an important role in pest management. Here, we isolated Bacillus thuringiensis-like bacteria from the soil samples primarily collected from North East region of India along with some states viz., Haryana, Punjab, Maharashtra, West Bengal and Uttarakhand and studied their toxicity against the above two insect pests at 10 gg/g along with standard strain B. thuringiensis subsp. kurstaki HD-I and at 1 pg/g Pseudomonasfluorescens based MVPII expressing CrylAc toxin and AUG-5. Isolates AUG-5 and GTG-7 proved toxic to more than 75% larvae on the 4h as well as 7h day of the treatment of the neonates of H. armigera. The AUG-5 isolate was also effective against S. litura. Ten effective isolates (AUG-5, GTG-4, GTG-7, GTG-9, GTG-42, GTG-64, GTG-70, GTG-3S, GTG-4S and GTG-6S) were characterized using biochemical and 16S rDNA analysis. Nearly, all the isolates tested positive for utilizing monosaccharides. All selected B. thuringiensis isolates showed resistance to ampicillin and co-trimoxazole except AUG-5 to- co-trimoxazole. AUG 5 and GTG-7 were highly toxic to both insects, and possessed cryl, cry1A and cry2 genes. These isolates AUG-5 and GTG-7 also contained high CrylAc (104.8 and 88.32 ng/mg) and Cry2Ab (3792 and 1305.9 ng/mg), respectively in their spore-crystal complex. Both, AUG-5 and GTG-7 isolates, could be considered for further development as bioinsecticides. The present study has established the diversity and richness of B. thuringiensis-like isolates in soils collected from north eastern region of India. PMID- 29466623 TI - Differential antibrucella activity of bovine and murine macrophages. AB - Brucella abortus is. an intracellular pathogen affecting macrophages. Macrophages release some antibrucella componen such as lysozymes (LZ), reactive-oxygen species (ROS) and reactive nitrite intermediates (RNI) which prevent intracellul survival of Brucella. The present study compared the antibrucella activity of bovine and murine macrophages followir stimulation with B. abortus lipopolysaccharides. Our results revealed increased production of these antibrucella substanci in murine macrophages as compared to bovine macrophages. The differential production of these antibrucella componen explained the differential B. abortus killing ability of these species (bovine and mice) that was measured in terms intramacrophagic survival of Brucellae in murine and bovine macrophages. PMID- 29466624 TI - Effect of flavonoid rich fraction of Tephrosiapurpurea (Linn.) Pers. on complications associated with streptozotocin-induced type I diabetes mellitus. AB - Globally, diabetes is a serious health issue affecting one in 11 adults and consumes 12% of global health expenditure. Prevalence of dyslipidemia in diabetes is not uncommon since decades. Further, patients with type II diabetes have 2-4 folds more risk for cardiovascular disease (CVD). Plants with antioxidant potential are known to have beneficial effects in diabetes and its complications: Natural compounds, flavonoids particularly, ameliorate hyperglycemia as well as CVD. Here, we evaluated common wasteland weed Tephrosia purpurea, used traditionally as folk medicine to treat many disorders including diabetes. We studied the effect of 8-wk treatment of flavonoid-rich fraction of T. purpurea (FFTp) (40 mg/kg/day/p.o.) on various biochemical, cardiovascular and lenticular parameters on streptozotocin (STZ) (45 mg/kg, i.v.) induced type I diabetic rats. STZ administration produced significant hyperglycemia, dyslipidemia, and altered cardiac biomarkers like lactate dehydrogenase, creatinine kinase and reduced antioxidants in lenticular tissues of rats. Treatment with FFTp significantly prevented STZ-induced hyperglycemia, dyslipidemia as well as cardiovascular markers. We observed decreased rate of pressure development (+dp/dt) and decay ( dp/dt) in STZ diabetic hearts which was prevented by FFTp. Further, the soluble protein levels and the antioxidants were also elevated in the diabetic rats by the treatment. In conclusion, our data suggest that FFTp produces beneficial effects on diabetes induced cardiovascular complications and cataract. Such beneficial actions may be attributed to the antioxidant property of flavonoids, quercetin or rutin, present in T. purpurea. PMID- 29466625 TI - Antioxidant activity of Wattakaka volubilis (Linn. f.) leaf extract in carbon tetrachioride induced mice. AB - Plants are natural source of antioxidants which ameliorate a variety of diseases. In this study, we determined the in vitro and in vivo antioxidant activity of methanolic, polyphenolic and sapogenin mixture leaf extracts of Wattakaka volubilis (Linn.f.) Stapf, an ayurvedic medicinal plant. The in vitro antioxidant activity was tested spectrophotometrically by measuring ferric reducing power, DPPH and hydroxyl radical scavenging activity. Whereas the in vivo antioxidant activity was determined by estimation of enzymes catalase, superoxide dismutase (SOD), peroxidase and lipid peroxidation. In vitro study results showed that the tested extracts were capable of reducing ferric ion and scavenging free radical as well as hydroxyl radical. Treatment of mice with single dose of CCd4 resulted in decreased level of catalase, superoxide dismutase (SOD) and peroxidase, hut with 3-fold increase in lipid peroxidation. However, pretreatment of mice with methanolic and polyphenolic sample extracts caused prevention of catalase, and peroxidase when compared with control, where as lipid peroxidation was brought back to normal. NOS activity was also found significantly decreased. PMID- 29466626 TI - Validation of PCR based detection system for aflatoxin producing molds. AB - Aflatoxins are polyketide secondary metabolites that are produced by certain fungal species in the Aspergillus section Flavi, particularly Aspergillus flavus and Aspergillus parasiticus which contaminate human food as well as animal feed. These are among the most carcinogenic substances known. Due to the toxic and carcinogenic properties of aflatoxins, there is a need to develop reliable methods to detect the presence of aflatoxigenic Aspergilli in contaminated food and feed. Not all Aspergillus strains are able to produce aflatoxins. It requires a detection methodology which can specifically distinguish between the aflatoxin producing and nonproducing strains of Aspergillus. Present communication reports validation of a PCR based detection system based on three genes viz., nor-1, apa 2 and omt-1 involved in aflatoxin biosynthesis, that can specifically distinguish the two aflatoxin producing species viz. Aspergillus flavus ,and Aspergillus parasiticus from non-producers i.e., A. niger, A. fumigates and A. oryzae. PMID- 29466627 TI - A rapid and efficient protocol for in vitro multiplication of genetically uniform Stevia rebaudiana (Bertoni). AB - Stevia rebaudiana (Bertoni), commonly called candy leaf or sweet leaf, endemic to South America, is an important medicinal plant. As a source of low calorie natural sweetener 'stevoside', it is used in obesity, diabetes, treatment of heartburn and tooth decay, and also serves as a food supplement. Large scale commercial propagation of S. rebaudiana demands a suitable protocol. Here, we propose an improved protocol for in vitro multiplication of S. rebaudiana from nodal explants. In this protocol, the effect of laboratory grade urea on multiple shoot induction from nodal explants was studied. The nodal explants were initially cultured on Murashige and Skoog (MS) basal media for 2 weeks which facilitated the axillary bud break. Further, culturing of these explants on MS medium fortified with 6 benzyl amninopurine (BAP) (2 mg/L) and Naphthalene acetic acid (NAA) (1 mg/L) with and .without urea (5 mg/L) for a period of 40 days revealed maximum shoot production of 44.56 from a single nodal explant in media supplemented with urea as compared to 22.44 without urea. The differences in the number of shoots produced were significant and these shoots readily rooted in MS media with NAA (4 mg/L). Primary and secondary hardening was successful in these plants. There were no visible morphological abnormalities observed in the micropropagated plantlets. Genetic analysis from random samples also revealed that these plants are genetically uniform. The advantage of the present protocol is that the complete process of multiple shoot induction, rooting and hardening could be completed within a period of 6 months as compared to the existing protocols. PMID- 29466628 TI - Influence of light intensity, temperature and CO2 concentration on growth and lipids in green algae and cyanobacteria. AB - Effects of the environmental variables such as light intensity (Vmol photons m-2 S-1), temperature (*C) and CO2 concentration (ppm) on chlorophyll, total soluble proteins and lipids were studied in selected microalgal strains from Chlorophyceae (Chlamydomonas sp., Scenedesmus sp., Chlorella sp., Kirchneriella sp.) and cyanobacteria (Nostoc sp.1, Anabaena sp., Nostoc sp. 2, Cylindrospermum sp.). Cultures were grown under controlled conditions at the National Phytotron Facility, Indian Agricultural Research Institute (IARI), New Delhi. Our results showed that chlorophyll concentration enhanced with increased C02. Chlorella exhibited the highest chlorophyll at 850 ppm CO2 and 28*C; for Chlamydomonas it was at 78 MUmol photons m-2 S-1 light intensity. In Cylindrospernum, total soluble proteins decreased with enhanced C02, and were highest at 18*C. In Anabaena, a light intensity of 65 MUmol photons m-2 S-1 was best for maximum total soluble proteins. In Chlorella, CO2 @ 850 ppm was most suited for maximum lipid accumulation. In Kirchneriella, increase in temperature, from 18*C up to 370C, increased total lipids; the highest was at 28'C. In Chlamydomonas, the light intensity of 78 MUmol photons m-2 S-1 was optimum for lipid accumulation and the maximum total lipids was 30.8 (% dry wt.). PMID- 29466629 TI - Diel variation in the catch of the shrimp Farfantepenaeus duorarum (Decapoda, Penaeidae) and length-weight relationship, in a nursery area of the Terminos Lagoon, Mexico. AB - The pink shrimp, Farfantepenaeus duorarum is an important commercial species in the Gulf of Mexico, which supports significant commercial fisheries near Dry Tortugas, in Southern Florida and in Campeche Sound, Southern Gulf of Mexico. There is information about the nictemeral behavior of the pink shrimp related to sunset, what is crucial to more accurate estimation of shrimp population biomass, and to assess the potential of this resource and its proper management. To contribute to the knowledge and the population dynamics of the species, shrimp surveys were conducted in a nursery area near "El Cayo" in the Northeastern part of Terminos Lagoon, Mexico during October 2010. Three sampling sites with substrate covered by submerged vegetation were chosen; two set of samples were collected at each site, one in the morning and the other just after sunset. Three trawls were performed per sampling site using a small otter trawl. A total of 1 418 shrimp (between 5.5 to 28.8 mm Carapace Length (CL)) were collected during the study; 1 416 F. duorarum and only two individuals of Litopenaeus setiferus. Shrimps CL and Total Length (TL) were measured in mm and individuals were weighted to the nearest 0.01 g. In general, shrimp biomass and density were significantly higher in all sites during dusk (biomass = 46.36 g.100 m-2, n = 1 344), than daylight samples (biomass = 2.78 g.100 m-2, n = 72). The One-way ANOVA and the Tukey test performed to evaluate variability in CL found significant differences between sites (CL = 14.12 mm, 12.46 mm and 15.13 mm, for site 1, 2 and 3 respectively, F = 64.92, P < 0.001) which might be related to the substrate type. The length-weight relationships reflected positive allometric growth for juveniles but isometric for subadults and two nonlinear power functions were estimated (W = 0.0004CL3.157 for juveniles, and W = 0.0009CL2.902 for subadults). The results of the analysis of covariance (ANCOVA) test indicated that the Total Length - Carapace Length (TL-CL) relationships were significantly different between juveniles and subadults, and two linear equations (TL = 2.615 + 4.476CL and TL = 8.931 + 4.062CL for juveniles and subadults respectively) were fitted. It is important that population assessment takes into account the day or night period as a bias factor when sampling the abundance of the juveniles of F. duorarum in this important nursery ground of the Campeche Sound.

AB - Some species of marine fish have complex relationships with coastal ecosystems during their reproductive periods, as the needle fish Tylosurus pacificus that forms spawning aggregations in gravel beaches in Utria Park. We described fishery and some aspects of the reproductive biology of T. pacificus and proposed some strategies to mitigate the impact of this event and associated ecological processes. Fisheries monitoring were conducted between April 2008 and February 2009 in the Utria National Park, Colombian Pacific. Catch volumes, length structure, sex ratio and fecundity (n= 84) were analyzed. The total length ranged among 60.5 and 104 cm with a mean and standard deviation of 85.35 +/- 9.09 cm. The average fertility of oocytes per gonad was 189 685.56, with a mode of 8 mm diameter and an asynchronous gonadal development. This species spawns collectively on the beach when the tide reaches the highest level during full and new moon, usually in the evening. Fishermen of a near town take advantage of the spawning aggregation of this species. The reproduction study of T. pacificus and ecological processes associated with their spawning, should be expanded to give adequate use, and ensure the sustainability of their fishery over the long term. PMID- 29466631 TI - Distribution of the deep-sea genus Bathypterois (Pisces: Ipnopidae) in the Eastern Central Pacific. AB - The genus Bathypterois (tripod fish) comprises 19 species of deep-sea fishes distributed worldwide. The biology and distribution of the species of this genus are relatively poorly known throughout the Eastern Central Pacific (ECP). This work aims to update the geographic and bathymetric distribution of species of Bathypterois throughout the ECP. To describe the influence of depth, temperature and dissolved oxygen concentrations (DO) on latitudinal and depth distribution of members of the genus throughout the Mexican Pacific, 51 specimens of B. atricolor (12 trawls) and 112 of B. ventralis (18 trawls), collected during TALUD project, were analyzed. Bathypterois atricolor had broader environmental niches (depth: 0.47, temperature: 0.46, DO: 0.39), and inhabits deeper and colder sites (Electivity positives: > 1 000 m, < 3.2 degrees C, 1.0-1.62 mL/L) than B. ventralis, which had narrow environmental niches (depth: 0.34, temperature: 0.32, DO: 0.28), with high affinity to warmer sites and lower DO concentrations (Electivity positives: 778-1 400 m, 3.3-5.8 degrees C, < 1.0 mL/L). Both species used different environmental strata (niche overlap; depth: 0.34, temperature: 0.32, DO: 0.28). The adaptation of B. atricolor to live in a broad range of DO concentrations explains its almost circumglobal distribution, while B. ventralis lives almost permanently in the Oxygen Minimum Zone (< 0.05 mL/L), so the DO could be a limiting factor, reducing its potential geographic and bathymetric distributions. None of these species had been previously recorded in the central Gulf of California, and B. ventralis had not been recorded along the West coast of Baja California. This study confirms that both species have a continuous distribution within the ECP, our new records extended the known northernmost range for B. atricolor by 886 km (from 22 degrees 46' N to 30 degrees 45' N) and for B. ventralis by 645 km (from 21 degrees 18' N to 27 degrees 07' N).

AB - Igarapes are Amazonian streams that are extremely susceptible to environmental changes. Due to the rapidly occurring riparian land use changes, and the several impacts these may have on fish assemblages, it is highly valuable to describe and understand the current relationships between these assemblages and the local environmental conditions, especially in barely know areas. In this research, we studied the taxonomic composition and fish assemblage attributes variation in three streams with different riparian conservation conditions: forest, intermediate and pasture. Samplings were performed every two months from October 2011 to September 2012, in three 1st order streams in the Machado River Basin, Rondonia. Fish were collected using trawls (seine net with a mesh size of 2 mm) and dip nets (2 mm mesh) along the entire stretch; the obtained samples were preserved and identified per site type. A total of 2 141 fish specimens belonging to 59 species, 17 families and five orders were recorded. Unlike the intermediate and pasture streams, the forest stream showed a high richness and low abundance. The forested stream exhibited the highest diversity and evenness value, and had low dominance, unlike the other streams. The variance partitioning and partial Redundancy Analysis (pRDA) indicated that assemblage composition was significantly explained by the environmental variables such as: depth, water velocity, pteridophytes and grasses, but not by spatial predictors. The non metric multidimensional scaling (NMDS) analysis showed that intermediate and pasture streams separated from the forested stream. We concluded that both, the stream environmental variables and fish assemblage attributes were influenced by the different conservation status and land cover. Given the influence of regional processes, which have a pervasive role in local fish assemblages, land use at the watershed scale is important, especially to explain the higher richness and diversity found in forested streams.

AB - The first lionfish sighting at the National Park "Cayos de San Felipe" was in 2009 and could be a threat to its marine ecosystem diversity and their capacity to generate services. To analyze the incidence of the lionfish invasion in the area, an annual sampling was conducted between 2013 and 2015. Lionfish abundance and size was investigated on mangroves through visual census on ten transects of 30x2 m/station, and on coral reefs (15 and 25 m deep) with stereo video on six transects of 50x2 m/station. Additionally, incidence of potential native competitors and predators on coral reefs were also estimated. Over the three years, the average density of lionfish varied between 0.0-1.3 indiv./100 m2 per sample stations and it was not significantly different among habitats (mangroves with 0.6 indiv./100 m2, reefs at 15 m - 0.4 indiv./100 m2 and reef at 25 m with 0.3 indiv./100 m2). Lionfish's density was equal to or lower than competitors' density, and was equal to or higher than predator's density in both depths. While lionfish density on mangroves and on reefs at 25 m remained temporally stable, it decreased on reefs at 15 m. Temporary increase in the competitor's density was observed and the predator's density did not change during the monitored time. Lionfish size varied between 5 and 39 cm; the average fish size from mangroves (12.6 cm) was consistently lower than from reefs (25.2 cm) and showed no variations among years. Lionfish size in reefs was higher than competitor's size and lower than that of predator. Results showed that in the park: 1) mangroves represent lionfish nursery areas; 2) incidence of reef lionfish was not as high as in other areas of Cuba and the Caribbean; and 3) lionfish abundance in reefs tended to decrease over the years, without the intervention of extractive activities or high abundance of large size native groupers. In this sense, recommendations are made to continue monitoring and to investigate lionfish effects and factors that are regulating its incidence in the park.

AB - Endemic populations of Hechtia perotensis have been described in Puebla and Veracruz, Mexico. Good quality seed collections can be used in conservation, research and ecological restoration. To evaluate seed quality of wild and endemic species, some compounds are used as effective promoters of germination, such as potassium nitrate (KNO3) and gibberellic acid (AG3), because they increase seed germination capacity and reduce latency. The triphenyl tetrazolium chloride (tetrazolium) test correlates seed viability because it is based on the activity of dehydrogenases in live tissues that catalyze mitochondrial respiration. The objective of this study was to obtain information on size and weight of capsules and seeds and seed germination and viability of H. perotensis, collected in Veracruz in the year 2012 and 2015. The hypotheses were 1) that seed germination and viability are independent of the year of collection, 2) that there is a tetrazolium concentration that can identify seed viability better than others, and 3) that pretreatment with KNO3 or AG3 improves seed germination. Seed germination was assessed using a completely randomized design with three treatments (control and the germination promoters 0.2 % KNO3 and 500 mg/L AG3), four treatments for the viability test (control, 0.2, 0.5 and 1.0 % of tetrazolium) and six replicates for each treatment. A total of one hundred seeds for germination experiments, and 25 seeds for the viability test were used. The results between and within years were analyzed with ANOVA and multiple comparison with the Tukey test. The proportion of non-germinated seeds was quantified along with the number of normal and abnormal seedlings, seeds with viable embryo, seeds without embryo, and seeds with low or no viability. On average, for the 2012 collected sample, 36 % had viable embryos, 7 % had low viability, 24 % were not viable and 33 % had no embryo. This result was significantly different from the 2015 sample, for which 87 % of seed showed viable embryos, 10 % had low viability, 0 % was not viable and 3 % had no embryo. Seed germination was also significantly different between years (22 and 92 %) Pregerminative treatments did not improve germination. Seed germination and viability of H. perotensis significantly varied between years of seed collection.

AB - The scyphomedusae feed mainly on microscopic crustaceans, eggs and fish larvae, molluscs and some other jellyfishes. The distribution and abundance of the scyphomedusae has an economic and ecological impact as they are predators that have an influence on the population dynamics of other fisheries. This investigation took place in the lagoon system 'Arrastradero-Redonda', Tabasco, from September 2013 to August 2014, with the purpose to provide information on the distribution, and spatial and temporal abundance of Stomolophus meleagris; along with its relation to environmental parameters. A total of 10 stations were defined and biological samples were taken on a monthly basis during this annual cycle. For this purpose, three pulls with a beach seine monofilament (20m long by 3m height, mesh opening 1.5 cm, 5 to 10 minutes) per station were made within a 1 km2 area. Information obtained was used to calculate the fishing efficiency analysis (CPUE con org./Evaluated Area Unit) and to determine the relationship with the environmental parameters. Our results showed that the abundance in the stations 1 to 3 was from 7 to 19 org./km2 from April to August 2014; less organisms were observed in stations 6 to 10 (an average of 1 org./km2) from October 2013 to March 2014. The multiple correlation steps analysis indicated that there is a strong association between the CPUE and some environmental investigated variables, and a 70.9 % variability of the data was observed. The salinity resulted the most important variable because it determined a 64.3 % of variation; it was followed by the temperature with a 3.6 %; meanwhile, dissolved oxygen explained only the 2.9 %, this was mainly because within the area there are several geological, oceanographic and biological factors that favor the distribution of this species due to seawater contribution through the Tupilco bar. With the provided data with this investigation we were able to determine the fishery potential of this resource for Tabasco state. However, additional research is required to allow an extended quantification of this resource, to determine the commercial exploitation areas, and drive studies about reproductive and feeding habits, that may provide the necessary information to establish plans for sustainable use.

AB - Snooks C. undecimalis and C. ensiferus are important fishery resources in their distribution area. In Venezuela they are caught by artisanal fisheries along the entire coast. However, studies on their biology that would help establish fishing regulations are scarce. To study reproduction aspects of these species, we analyzed 1 325 individuals of C. undecimalis and 2 025 of C. ensiferus caught by artisanal fishing in the Laguna de Tacarigua in Northern Venezuela, from July 2009 to September 2010. Total length, total weight, sex and stage of gonadal development were recorded. The sex ratio varied throughout the year: there was a significant difference in favor of C. undecimalis males (1.5:1), and C. ensiferus females (1:3.3). Differences were also evident in the sexual proportion at each size group. For both species, males dominated in the lower size ranges while females dominated in the larger size ranges. These results suggested sequential hermaphroditism (protrandry) in both species. Size at sexual maturity (Lm50) for C. undecimalis was ?= 73.6 and ?= 59.3 cm, and ?= 26 and ?= 21.5 cm for C. ensiferus. C. ensiferus reproduced throughout the year with two periods of higher intensity (August to September and February to April). Although we found very few mature individuals for C. undecimalis, February showed an important reproduction peak. Growth differences were found between males and females of C. undecimalis: positive allometry for females (P= 0.0022*L3.353) and negative allometry for males (P= 0.0108*L2.945). Both males and females of C. ensiferus showed a positive allometric relationship (P= 0.0049*L3.235). Lack of fishing regulations and controls, evidenced in this study by significant volumes of immature individuals in the catches, and the particular reproductive biology of these species, strongly indicates the need to establish regulations to ensure their responsible use. We recommend establishing a closed season during the first quarter of the year and minimum catch sizes for both species. PMID- 29466638 TI - [Economic potential of ornamental fish catching under federal protection in Mexico.]. AB - Ornamental fisheries are economically viable activities in developing countries due to the fact that aquaria have become a worldwide hobby. In Mexico, the fishery has been conducted since the 1980s, especially in the Baja California Peninsula, but nevertheless, there are no adequate records of commercial production, or about the economic gain due to the exploitation of the resource. The objective of this paper was to calculate the maximum allowable catch for the five ornamental fishes included in the NOM-059-SEMARNAT (protected by federal mandate), and the net monetary gain that the resource might generate. Censuses (N=1 610) were conducted in 21 reef sites of the Mexican Pacific and Gulf of California in order to estimate population density of each taxon; also, natural mortality rate (M) was calculated from maximum size (Linfinity), individual growth rate (k) and temperature (C), and the total allowable catch was estimated on the basis of M. Finally, considering the prices of the species paid to fishermen at the beach, an estimation of the economic value of a single fishing season for an area of 220 hectares (representative of the catch area assigned in average to a cooperative in Mexico) was produced. The results indicated that the areas with the best economic potential were Encantadas Islands, Los Angeles Bay, and San Lorenzo Archipelago (all in the state of Baja California). Outside of the gulf (where no legal ornamental fisheries exist) the potentially more rentable locations were Marietas Islands (Jalisco), and the Revillagigedo Islands. Aquarium fisheries may be a viable activity in several of the analyzed areas of the country, however, the potential gain that harvest represents is not enough to fully sustain an organized group that would perform it; for that reason the ornamental fishery should be seen as an alternative commercial activity. Finally, to guarantee this activity to be a rentable and sustainable fishery, we recommended that, the existing rules defined by the Mexican federal government should be applied to control the catch quotas.

We studied its population at Bahia Portete, in order to survey the nesting activities and to obtain valuable information for a conservation management program. This study was undertaken with the participation of the Wayuu community using the Agreement Conservation Model, and took place during July 2007, August 2008, June and August 2009, and March to August 2010 and 2011. Sampling surveys were made by the use of transects along the coast, in order to find nests. For each nesting area found, we recorded the nests biometrics, eggs and hatchlings, fertility of the eggs and reproductive events. We explored a total of 55.12 km, and determined four nesting areas. Colonial nesting and the environmental variables were factors that affected the hatchling success. From the total of nests found, 37 % were oriented towards North, and 48 % were built next to Stenocereus griseus. Juyi island substrate was mostly constituted by sand (71.9 %, 71.44 %). The average number of eggs by nest was 28.42 +/- 6.63, the largest egg diameter was 71.84 +/- 3.54 mm, the average nest weight was 81.54 +/- 9.99 g, and the hatchlings presented an average length of 25.47 +/- 1.16 cm. For this specific site in Colombia, the reproductive period begins in March and ends in August. The few areas of nesting and the 95 % fertility suggest the performance of a conservation management program for this species at Bahia Portete.

AB - Parasites play a crucial role in the ecology of animals. They also appear to be important in mechanisms underlying sexual selection processes. In this article we study the prevalence, effect and potential role in sexual selection of the protozoon Trypanosoma evansi in capybaras, Hydrochoerus hydrochaeris. We collected our samples from the annual capybara cull of a ranch in Venezuela, using the volume of the snout scent gland as an indicator of dominance; the residuals of body weight as indicators of condition; and the residuals of the spleen mass as indicators of immune function. Overall prevalence was 30.9% (N=97) with no difference between males and females and no relation between infection with T. evansi and condition. However, we found that infected animals had larger spleens (residuals), indicating an immunological cost of the infection. Further, males with larger snout scent glands (more dominant) were less likely to be infected than males with smaller glands (less dominant) suggesting that by choosing males with a large gland, females may be using the gland as an indicator of health, which is consistent with the "good genes" view of sexual selection. PMID- 29466641 TI - [Basic biological parameters for Pseudocurimata lineopunctata (Characiformes, Curimatidae) conservation in the Anchicaya River of the Cauca Valley, Colombia]. AB - Pseudocurimata lineopunctata represents an important nutritional source for local human communities in Colombia and Ecuador. Although the yearly catch of this fish is low (590 kg/year), there are no restrictions on minimum size, and this species is categorized as vulnerable with moderate extinction risk by the Regional Autonomous Corporation of the Cauca Valley (Colombia). To support conservation programs, biological data of the target species are required. Therefore, the aims of this study were to describe the sex ratio, distribution, size to weight ratio, macroscopic stages of reproductive maturity, fecundity, and size at first sexual maturity for P. lineopunctata. For this, fish samples were captured with nets over nine months (February-October) in 2007. The total length (Lt) of the captured fish ranged between 10.7 and 16.5 cm, with total weight (Pt) between 25.0 and 67.5 g. Females represented 52.6 % of the sample group while males represented 47.4 %, and differences in sex ratio were observed in relation to fish size. For all sampled months, the fish captured showed an advanced maturity state. Based on analyses of the gonadosomatic index (IGS), gonadic index (IG), and Fulton's condition factor (K), and two spawning peaks were determined, one in June-July, and the other in September-October. The size at first sexual maturity was 9.2 cm for females and 10.1 cm for males. Absolute fecundity was estimated as 3 598 oocytes/g?. It is necessary to carry out additional investigations on the reproduction of this species, to support future repopulation programs. PMID- 29466642 TI - Reproductive cycle of the endemic and threatened fish Puntius shalynius (Cypriniformes: Cyprinidae) in Meghalaya, India. AB - Puntius shalynius is a highly endemic freshwater minor carp that is economically important and isthreatened because of its ornamental value. The present investigation evaluated this barb gonadal maturation,based on morphology and spawning of this species in the Umiam river, Meghalaya, India. The population ofthis indigenous fish has declined due to its fragmented distribution and exploitation as an ornamental fish. Thereproductive cycle of P. shalynius was studied for the first time. A total of 609 fish samples were randomly collectedfrom the river for a period of two years during January 2010 and December 2011. Five maturity phases(rest, primary growth, secondary growth, ripe and spent) were observed on the basis of ovarian and testicularmacroscopic evaluation throughout the annual cycle. Peak spawning activity was observed in the month of June/July and it coincided with the start of the monsoon season. The study showed that the fish spawns once in a yearwith single spawning peak and that the species is a low fecund fish. It is important to conserve this species forits unique ecological value and urgent management policies should promote its sustainable utilization. PMID- 29466643 TI - Divergent predation environment between two sister species of livebearing fishes (Cyprinodontiformes: Poeciliidae) predicts boldness, activity, and exploration behavior. AB - Predators can influence a variety of prey traits, including behavior. Traits such as boldness, activity rate, and tendency to explore can all be shaped by predation risk. Our study examines the effects of predation on these behaviors by considering a natural system in which two sister species of livebearing fishes, Brachyrhaphis roseni and B. terrabensis, experience divergent predation environments. In February of 2013, we collected fish in the Rio Chiriqui Nuevo drainage, Chiriqui, Panama, and conducted behavioral assays. Using open-field behavioral assays, we evaluated both juveniles and adults, and males and females, to determine if there were differences in behavior between ontogenetic stages or between sexes. We assessed boldness as 'time to emerge' from a shelter into a novel environment, and subsequently measured activity and exploration within that novel environment. We predicted that B. roseni (a species that co-occurs with predators) would be more bold, more active, and more prone to explore, than B. terrabensis (a species that does not co-occur with predators). In total, we tested 17 juveniles, 21 adult males, and 20 adult females of B. roseni, and 19 juveniles, 19 adult males, and 18 adult females of B. terrabensis. We collected all animals from streams in Chiriqui, Panama in February 2013, and tested them following a short acclimation period to laboratory conditions. As predicted, we found that predation environment was associated with several differences in behavior. Both adult and juvenile B. roseni were more active and more prone to explore than B. terrabensis. However, we found no differences in boldness in either adults or juveniles. We also found a significant interaction between 'sex' and 'species' as predictors of boldness and exploration, indicating that predation environment can affect behaviors of males and females differently in each species. Our work demonstrates the importance of considering sex and life history stage when evaluating the evolution of behavior.

AB - Deforestation in Amazon forests is one of the main causes for biodiversity loss worldwide. Ants are key into the ecosystem because act like engineers; hence, the loss of ants' biodiversity may be a guide to measure the loss of essential functions into the ecosystems. The aim of this study was to evaluate soil ant's richness and to estimate whether higher taxa levels (Subfamily and Genus) can be used as surrogates of species richness in different vegetation types (fallows, old-growth forests and agroforestry systems) in Eastern Amazon. The samples were taken in 65 areas in the Maranhao and Para States in the period 2011-2014. The sampling scheme followed the procedure of Tropical Soil Biology and Fertility (TSBF). Initially, the vegetation types were characterized according to their age and estimated species richness. Linear and exponential functions were applied to evaluate if higher taxa can be used as surrogates and correlated with the Pearson coefficient. In total, 180 species distributed in 60 genera were identified. The results showed that ant species richness was higher in intermediate fallows (88) and old secondary forest (76), and was lower in agroforestry systems (38) and mature riparian forest (35). The genus level was the best surrogate to estimate the ant's species richness across the different vegetation types, and explained 72-97 % (P < 0.001) of the total species variability. The results confirmed that the genus level is an excellent surrogate to estimate the ant's species richness in the region and that both fallows and agroforestry systems may contribute in the conservation of Eastern Amazon ant community. PMID- 29466645 TI - Oocyte distribution within and between ovary lobes is largely homogeneous in Lachnolaimus maximus (Perciformes: Labridae). AB - Studies of fish reproductive biology often involve quantitative estimates based on histological sections of the ovaries. Prior characterization of gonad oocyte distribution patterns in females is fundamental to these studies. Heterogeneous distribution requires a standardized sampling protocol to prevent bias in data such as fecundity estimations. In contrast, homogeneous distribution allows sampling of any portion of the gonads with no risk of bias. A preliminary study was done of gonad oocyte distribution mode in a hogfish Lachnolaimus maximus population in the southern Gulf of Mexico. A total of 23 sexually-active females were selected and classified by reproductive stage. Six histological sections were taken from the anterior, middle and posterior regions of the left and right ovary lobes of each individual. Digital image processing (AxioVision and Image ProPlus programs) was used to estimate oocyte density per unit area in different development stages. Contingency tables were used to analyze oocyte distribution frequencies between the regions of each lobe and between the lobes of each ovary. This was supported with a Pearson's chi2 test for goodness-of-fit and a replicated G test to confirm distribution heterogeneity. Oocyte type distribution was homogeneous in almost all the females regardless of ovary region or lobe. This was particularly the case for females in the actively spawning reproductive subphase. Females in this subphase are normally used to estimate batch fecundity in fish species such as L. maximus, which have asynchronous oocyte development and batch spawning. However, heterogeneity was present in tertiary vitellogenesis oocytes in the right lobe of females in the spawning capable reproductive phase. In these cases, it is preferable to take histological sections from any region of the left ovary lobe to ensure unbiased estimation of fecundity and adequate characterization of this species' sexual cycle. PMID- 29466646 TI - Estimation of genetic variation in closely related cycad species in Ceratozamia (Zamiaceae: Cycadales) using RAPDs markers. AB - The Ceratozamia norstogii complex from Southern Mexico is made up of four closely related taxa and occurs in similar habitats (Quercus forest). All have linear lanceolate leaflets with great similarity between them, especially in juvenile stages, but differentiate with age. There has been debate regarding delimitation of species due to character loss in herbarium specimens. The aim of this study was to determine the genetic variation, and to measure genetic similarity between the four taxa. We studied populations in Cintalapa (Chiapas) for C. alvarezii and C. norstogii; the Sierra Atravesada (Oaxaca) for C. chimalapensis, and Villa Flores (Chiapas) for C. mirandae. One population for each taxon was sampled (only one population is known for C. alvarezii) 11-15 randomly chosen adult individuals were sampled. Twenty-eight primers were tested of which five were polymorphic using the RAPD'S technique. The data were analyzed using Bayesian methods. Results revealed low genetic diversity, and a differentiation was found between species, suggesting a recent divergence. A previous morphological and anatomical study on the complex has found the taxa to be distinct. However, the results of this study have shown that the C. norstogii species complex is in a divergence process, probably through genetic drift and founder effects. PMID- 29466647 TI - [Leaf-litter breakdown as a tool to assess the functional integrity of high Andean streams of Southern Ecuador]. AB - The ecological condition of tropical Andean rivers are threatened by many human activities including changes in land use and cover in watersheds. Current protocols diagnose the structural condition of streams but not their function. In this study we proposed an assessment tool using the leaf-litter breakdown as a measure of the functional condition and health of high Andean streams in Southern Ecuador, including methodology and threshold values adapted to local conditions. We selected 15 streams in three micro-basins (Mazan, Llaviuco and Matadero) within or in the vicinity of Cajas National Park where we deployed litterbags for 15, 28 and 64 days. We used two types of mesh (coarse and fine) for the litterbags in order to separate the contribution of macro-invertebrates and microorganisms in the decomposition process and also tested two different leaf substrates: Alder (Alnus acuminata) and Miconia (Miconia bracteolata). In each collection period we determined physical and chemical parameters, applied the riparian quality index (QBR-And) and river habitat index (IHF). Decomposition rates (-k) were determined from the time period at which approximately 50 % ash free mass would have been lost. We used Ktotal and the ratio of the rate of decomposition between coarse and fine mesh (Kg/Kf) to define the functional condition thresholds. To test the metrics sensitivity we used graphical methods, one-way ANOVA and discriminative efficiency (ED). The analysis of watershed land use and cover showed a gradient of intervention: Matadero >= Llaviuco > Mazan. The composition of the environmental variables of Mazan streams were different with respect to Llaviuco and Matadero, whose values were similar to each other. The QBR-And index showed a significant gradient from very low levels in Matadero (27.5), moderately high values in Llaviuco (66.5) to high values in Mazan (87). Alder leaf-litter breakdown rates were significantly faster in Mazan than in Matadero and Llaviuco streams, while breakdown rates of Miconia were not significantly different among watersheds. The Kg/Kf ratio was significantly higher in Mazan compared to Llaviuco and Matadero, which did not differ. We consider the Kg/Kf metric sensitive enough to discriminate impacts in the studied areas. Our results support the use of the leaf-litter breakdown as an appropriate tool to assess functional ecological condition, complementing the structural assessments of these Andean rivers. PMID- 29466648 TI - Reproductive pattern of the large fruit-eating bat, Artibeus amplus (Chiroptera: Phyllostomidae) in the Venezuelan Andes. AB - Bimodal polyestry is the most common reproductive pattern in tropical bats, and it consists in producing one offspring per female twice a year. Reproductive patterns are closely related to rainfall regimes, frequently occurring twice a year in tropical regions. The goal of our study was to determine the reproductive pattern of the large fruit-eating bat, Artibeus amplus Handley, 1987 in a cave in the Venezuelan Andes inhabited by a large, stable colony. Thus, in this study we describe for the first time this important biological aspect of this unknown Neotropical bat species through the examination of external reproductive characteristics of males (inguinal or scrotal testes) and females (pregnant, lactating, post-lactating), based on 211 individuals (120 males and 91 females) captured between September 2008 and August 2009, in Cueva del Parque Las Escaleras, Estado Tachira, Venezuela. During this period of monthly sampling for a full year, most males displayed large scrotal testes, averaging 10 mm maximum length. The examination of females indicated that although pregnancy was first observed in November 2008, it reached a maximum during January and February 2009. Although adult males with scrotal testes throughout the year could imply that females have more than one pregnancy, our results suggested a seasonally monoestrous reproductive pattern for A. amplus. This study represents the first report of reproductive pattern for this poorly-known Neotropical frugivorous species. The observed monoestrous reproductive pattern supports the existence of synchronization between precipitation and reproduction. This synchronization has been frequently observed in most species of fruit bats. In this study, Artibeus amplus presumably adjust the parturition to anticipate the rainy season, as a strategy that allows maintenance of offspring during high availability of fruits. PMID- 29466649 TI - Preclinical efficacy against toxic activities of medically relevant Bothrops sp. (Serpentes: Viperidae) snake venoms by a polyspecific antivenom produced in Mexico. AB - The assessment of the preclinical neutralizing ability of antivenoms in Latin America is necessary to determine their scope of efficacy. This study was aimed at analyzing the neutralizing efficacy of a polyspecific bothropic-crotalic antivenom manufactured by BIRMEX in Mexico against lethal, hemorrhagic, defibrinogenating and in vitro coagulant activities of the venoms of Bothrops jararaca (Brazil), B. atrox (Peru and Colombia), B. diporus (Argentina), B. mattogrossensis (Bolivia), and B. asper (Costa Rica). Standard laboratory tests to determine these activities were used. In agreement with previous studies with bothropic antivenoms in Latin America, a pattern of cross-neutralization of heterologous venoms was observed. However, the antivenom had low neutralizing potency against defibrinogenating effect of the venoms of B. atrox (Colombia) and B. asper (Costa Rica), and failed to neutralize the in vitro coagulant activity of the venom of B. asper (Costa Rica) at the highest antivenom/venom ratio tested. It is concluded that, with the exception of coagulant and defibrinogenating activities of B. asper (Costa Rica) venom, this antivenom neutralizes toxic effects of various Bothrops sp venoms. Future studies are necessary to assess the efficacy of this antivenom against other viperid venoms.

AB - The Cuban archipelago has 79 Phyllophaga species with a 98.6 % of endemism, which makes the group ecologically and economically important, as some species are classified as crop pests. The aim of this study was to determine the relationship between the composition and structure of the Phyllophaga assemblages with their habitat type, considering both plant structure and level of human habitat disturbance. A total of 17 locations were sampled in Western Cuba during the rainy seasons of the period from 2011 to 2015; these differed in habitat types (forests and agroecosystems). Samplings followed standard methods and were made once with a light trap screen in each locality. A total of 1153 individuals of 24 Phyllophaga species were collected. The total abundance of collected individuals varied between 10 and 306, and species richness between two and nine species. The most abundant species was Phyllophaga dissimilis (Chevrolat) which also had the highest frequency of occurrence. Generally, less anthropized sites reflected richer and equitative communities; although these characteristics appeared in two sites that showed intermediate degree of disturbance. The non-metric multidimensional scaling showed that the most similar samples were those of the very anthropized sites; this similarity was given mainly by the abundance of Phyllophaga dissimilis, P. insualepinorum and P. puberula. Besides, the geographical distance was not related to the similarity of these assemblages. PMID- 29466651 TI - Reproductive biology of Sodhiana iranica (Brachyura: Gecarcinucidae) from Southern Iran. AB - Freshwater crab, Sodhiana iranica, is an endemic gecarcinucid crab that has been recently reported from Southern Iran. This research examined some reproductive aspects of S. iranica from Eelood freshwater spring, Southern Iran. Crabs were haphazardly sampled from April 2012 to April 2013, on a bimonthly basis. Measurements of Gonado-Somatic Index (GSI), Hepato-Somatic Index (HSI), oocyte diameter, and other aspects such as carapace width (CW) and total body weight (TW) were made in the captured specimens. Results showed a single seasonal reproductive cycle. Maturation and spawning occurred from December 2012 to April 2013 during the study period. The peaks of HSI were observed in April 2012 and February 2013. The oocyte diameter showed its most significant increase between August 2012 and February 2013. Considering the single seasonal breeding of S. iranica, a correct management, during the reproductive cycle, is necessary to support a healthy stock of this crab. PMID- 29466652 TI - Galapagos macroalgae: A review of the state of ecological knowledge. AB - Previous work has highlighted the critical role of macroalgal productivity and dynamics in supporting and structuring marine food webs. Spatio-temporal variability in macroalgae can alter coastal ecosystems, a relationship particularly visible along upwelling-influenced coastlines. As a result of its equatorial location and nutrient rich, upwelling-influenced waters, the Galapagos Archipelago in the East Pacific, hosts a productive and biodiverse marine ecosystem. Reports and collections of macroalgae date back to the Beagle voyage, and since then, more than three hundred species have been reported. However, their ecology and functional role in the ecosystem is not well understood. According to various disparate and in part anecdotal sources of information, abundant and diverse communities exist in the Western regions of the archipelago, the North is essentially barren, and in the central/South abundance and distribution is variable and less well defined. Both oceanographic conditions and herbivore influence have been theorized to cause this pattern. Extensive changes in macroalgal productivity and community composition have occurred during strong ENSO events, and subsequent declines in marine iguana (an endemic and iconic grazer) populations have been linked to these changes. Iguanas are only one species of a diverse and abundant group of marine grazers in the system, highlighting the potentially important role of macroalgal productivity in the marine food web. This review represents a first compilation and discussion of the available literature and presents topics for future research.

AB - Mining is one of the main economic activities in many tropical regions and is the cause of devastation of large areas of natural tropical forests. The knowledge of the regenerative potential of mining disturbed areas provides valuable information for their ecological restoration. The aim of this study was to evaluate the effect of age of abandonment of mines and their distance from the adjacent forest, on the formation of soil seed bank in abandoned mines in the San Juan, Choco, Colombia. To do this, we determined the abundance and species composition of the soil seed bank, and the dynamics of seed rain in mines of different cessation period of mining activity (6 and 15 years), and at different distances from the adjacent forest matrix (50 and 100 m). Seed rain was composed by five species of plants with anemocorous dispersion, and was more abundant in the mine of 6 years than in the mine of 15 years. There were no significant differences in the number of seeds collected at 50 m and 100 m from the adjacent forest. The soil seed bank was represented by eight species: two with anemocorous dispersion (common among the seed rain species) and the rest with zoochorous dispersion. The abundance of seeds in the soil did not vary with the age of the mine, but was higher at close distances to the forest edge than far away. During the early revegetation, the formation of the soil seed bank in the mines seems to be related to their proximity to other disturbed areas, rather than their proximity to the adjacent forest or the cessation activity period of mines. Therefore, the establishment of artificial perches or the maintenance of isolated trees in the abandoned mines could favour the arrival of bird-dispersed seeds at mines. However, since the soil seed bank can be significantly affected by the high rainfall in the study area, more studies are needed to evaluate management actions to encourage soil seed bank formation in mines of high-rainfall environments in the Choco region.

AB - The permanent monoculture of bananas and plantains farming in the middle of Rio Grande (Turbo - Antioquia) requires the application of a variety of pesticides. Inappropriate banana production practices in this region, have often led to waterbody pollution by agrochemicals from leachate and runoff processes. Currently, fish are the most common vertebrates used as bioindicators of water quality, because they are very sensitive to the presence of contaminants. Our main goal with this study was to compare the frequency of micronucleated erythrocytes (MNE) in peripheral blood specimens of fish Brycon henni, from two locations (polluted and unpolluted) in the Rio Grande. We evaluated the frequency of MNE in peripheral blood samples of fish B. henni from each location during two rainy seasons in 2010 and two dry seasons in 2011. Blood samples were collected, fixed for 24 h, and then were stained with Giemsa. Among results, we found that the median frequency of MNE was higher in the polluted site by agrochemical discharges (0.15+/-0.18), than in the unimpacted site (0.06+/-0.08). Furthermore, the frequency of MNE in B. henni during the dry season was highly significant for both locations. The results of this study indicated that the analysis of MNE in B. henni could be recommended as a suitable method for in situ detection of environmental genotoxins.

AB - Bacteria colonize highly diverse and complex environments, from gastrointestinal tracts to soil and plant surfaces. This colonization process is controlled in part by the intracellular signal cyclic di-GMP, which regulates bacterial motility and biofilm formation. To interrogate cyclic di-GMP signaling networks, a variety of fluorescent biosensors for live cell imaging of cyclic di-GMP have been developed. However, the need for external illumination precludes the use of these tools for imaging bacteria in their natural environments, including in deep tissues of whole organisms and in samples that are highly autofluorescent or photosensitive. The need for genetic encoding also complicates the analysis of clinical isolates and environmental samples. Toward expanding the study of bacterial signaling to these systems, we have developed the first chemiluminescent biosensors for cyclic di-GMP. The biosensor design combines the complementation of split luciferase (CSL) and bioluminescence resonance energy transfer (BRET) approaches. Furthermore, we developed a lysate-based assay for biosensor activity that enabled reliable high-throughput screening of a phylogenetic library of 92 biosensor variants. The screen identified biosensors with very large signal changes (~40- and 90-fold) as well as biosensors with high affinities for cyclic di-GMP ( KD < 50 nM). These chemiluminescent biosensors then were applied to measure cyclic di-GMP levels in E. coli. The cellular experiments revealed an unexpected challenge for chemiluminescent imaging in Gram negative bacteria but showed promising application in lysates. Taken together, this work establishes the first chemiluminescent biosensors for studying cyclic di-GMP signaling and provides a foundation for using these biosensors in more complex systems. PMID- 29466658 TI - Variability in Disinfection Resistance between Currently Circulating Enterovirus B Serotypes and Strains. AB - The susceptibility of waterborne viruses to disinfection is known to vary between viruses and even between closely related strains, yet the extent of this variation is not known. Here, different enteroviruses (six strains of coxsackievirus B5, two strains of coxsackievirus B4 and one strain of coxackievirus B1) were isolated from wastewater and inactivated by UV254, sunlight, free chlorine (FC), chlorine dioxide (ClO2), and heat. Inactivation kinetics of these isolates were compared with those of laboratory enterovirus strains (CVB5 Faulkner and echovirus 11 Gregory) and MS2 bacteriophage. FC exhibited the greatest (10-fold) variability in inactivation kinetics between different strains, whereas inactivation by UV254 differed only subtly. The variability in inactivation kinetics was greater between serotypes than it was among the seven strains of the CVB5 serotype. MS2 was a conservative surrogate of enterovirus inactivation by UV254, sunlight, or heat but frequently underestimated the disinfection requirements for FC and ClO2. Similarly, laboratory strains did not always reflect the inactivation behavior of the environmental isolates. Overall, there was considerable variability in inactivation kinetics among and within enteroviruses serotypes, as well as between laboratory and environmental isolates. We therefore recommend that future disinfection studies include a variety of serotypes and environmental isolates. PMID- 29466659 TI - Soil Bacteria Override Speciation Effects on Zinc Phytotoxicity in Zinc Contaminated Soils. AB - The effects of zinc (Zn) speciation on plant growth in Zn-contaminated soil in the presence of bacteria are unknown but are critical to our understanding of metal biodynamics in the rhizosphere where bacteria are abundant. A 6-week pot experiment investigated the effects of two plant growth promoting bacteria (PGPB), Rhizobium leguminosarum and Pseudomonas brassicacearum, on Zn accumulation and speciation in Brassica juncea grown in soil amended with 600 mg kg-1 elemental Zn as three Zn species: soluble ZnSO4 and nanoparticles of ZnO and ZnS. Measures of plant growth were higher across all Zn treatments inoculated with PGPB compared to uninoculated controls, but Zn species effects were not significant. Transmission electron microscopy identified dense particles in the epidermis and intracellular spaces in roots, suggesting Zn uptake in both dissolved and particulate forms. X-ray absorption near-edge structure (XANES) analysis of roots revealed differences in Zn speciation between treatments. Uninoculated plants exposed to ZnSO4 contained Zn predominantly in the form of Zn phytate (35%) and Zn polygalacturonate (30%), whereas Zn cysteine (57%) and Zn polygalacturonate (37%) dominated in roots exposed to ZnO nanoparticles. Inoculation with PGPB increased (>50%) the proportion of Zn cysteine under all Zn treatments, suggesting Zn coordination with cysteine as the predominant mechanism of Zn toxicity reduction by PGPB. Using this approach, we show, for the first time, that although speciation is important, the presence of rhizospheric bacteria completely overrides speciation effects such that most of the Zn in plant tissue exists as complexes other than the original form. PMID- 29466661 TI - Heterogeneity in Nitrogen Sources Enhances Productivity and Nutrient Use Efficiency in Algal Polycultures. AB - Algae hold much promise as a potential feedstock for biofuels and other products, but scaling up biomass production remains challenging. We hypothesized that multispecies assemblages, or polycultures, could improve crop yield when grown in media with mixed nitrogen sources, as found in wastewater. We grew mono- and poly cultures of algae in four distinct growth media that differed in the form (i.e., nitrate, ammonium, urea, plus a mixture of all three) but not the concentration of nitrogen. We found that mean biomass productivity was positively correlated with algal species richness, and that this relationship was strongest in mixed nitrogen media (on average 88% greater biomass production in 5-species polycultures than in monocultures in mixed nitrogen treatment). We also found that the relationship between nutrient use efficiency and species richness was positive across nitrogen treatments, but greatest in mixed nitrogen media. While polycultures outperformed the most productive monoculture only 0-14% of the time in this experiment, they outperformed the average monoculture 26-52% of the time. Our results suggest that algal polycultures have the potential to be highly productive, and can be effective in recycling nutrients and treating wastewater, offering a sustainable and cost-effective solution for biofuel production. PMID- 29466660 TI - A Versatile Approach to Noncanonical, Dynamic Covalent Single- and Multi-Loop Peptide Macrocycles for Enhancing Antimicrobial Activity. AB - Peptide oligomers offer versatile scaffolds for the formation of potent antimicrobial agents due to their high sequence versatility, inherent biocompatibility, and chemical tunability. Though many methods exist for the formation of peptide-based macrocycles (MCs), increasingly pervasive in commercial antimicrobial therapeutics, the introduction of multiple looped structures into a single peptide oligomer remains a significant challenge. Herein, we report the utilization of dynamic hydrazone condensation for the versatile formation of single-, double-, and triple-loop peptide MCs using simple dialdehyde or dihydrazide small-molecule cross-linkers, as confirmed by MALDI-TOF MS, HPLC, and SDS-PAGE. Furthermore, incorporation of aldehyde-containing side chains onto peptides synthesized from hydrazide C-terminal resins resulted in tunable peptide MC assemblies formed directly upon resin cleavage post solid phase peptide synthesis. Both of these types of dynamic covalent assemblies produced significant enhancements to overall antimicrobial properties when introduced into a known antimicrobial peptide, buforin II, when compared to the original unassembled sequence. PMID- 29466662 TI - Tracing the Uptake, Transport, and Fate of Mercury in Sawgrass ( Cladium jamaicense) in the Florida Everglades Using a Multi-isotope Technique. AB - The role of macrophytes in the biogeochemical cycle of mercury (Hg) in the Florida Everglades is poorly understood. Stable isotope tracer techniques were employed to investigate Hg uptake by sawgrass ( Cladium jamaicense) from soil and atmospheric pathways and the fate of Hg after absorption. Our results suggest that soil spiked 201Hg2+ was rapidly taken up by roots and transported to aboveground parts. The spiked 201Hg that was transported to the aboveground parts was trapped; no release of the spiked 201Hg from the leaf to the air was detected. Atmospheric 199Hg0 exposure experiments revealed that the majority of the previously deposited 199Hg0 taken into the leaf was fixed, with a very limited proportion (1.6%) available for re-emission to the atmosphere. The percentage of 199Hg0 fixed in the leaf will help reduce the model uncertainty in estimating the Hg0 exchange over the air-vegetation surface. We propose that sawgrass needs to be viewed as an important sink for atmospheric Hg0 in the regional Hg mass balance; this would have important implications for the critical loads of Hg to the Everglades. The multi-isotope tracer technique could be an effective tool to identify the role of plants in biogeochemical cycling of Hg in other ecosystems. PMID- 29466663 TI - Cis-to- Trans Isomerization of Azobenzene Derivatives Studied with Transition Path Sampling and Quantum Mechanical/Molecular Mechanical Molecular Dynamics. AB - Azobenzene-based molecular photoswitches are becoming increasingly important for the development of photoresponsive, functional soft-matter material systems. Upon illumination with light, fast interconversion between a more stable trans and a metastable cis configuration can be established resulting in pronounced changes in conformation, dipole moment or hydrophobicity. A rational design of functional photosensitive molecules with embedded azo moieties requires a thorough understanding of isomerization mechanisms and rates, especially the thermally activated relaxation. For small azo derivatives considered in the gas phase or simple solvents, Eyring's classical transition state theory (TST) approach yields useful predictions for trends in activation energies or corresponding half-life times of the cis isomer. However, TST or improved theories cannot easily be applied when the azo moiety is part of a larger molecular complex or embedded into a heterogeneous environment, where a multitude of possible reaction pathways may exist. In these cases, only the sampling of an ensemble of dynamic reactive trajectories (transition path sampling, TPS) with explicit models of the environment may reveal the nature of the processes involved. In the present work we show how a TPS approach can conveniently be implemented for the phenomenon of relaxation-isomerization of azobenzenes starting with the simple examples of pure azobenzene and a push-pull derivative immersed in a polar (DMSO) and apolar (toluene) solvent. The latter are represented explicitly at a molecular mechanical (MM) and the azo moiety at a quantum mechanical (QM) level. We demonstrate for the push-pull azobenzene that path sampling in combination with the chosen QM/MM scheme produces the expected change in isomerization pathway from inversion to rotation in going from a low to a high permittivity (explicit) solvent model. We discuss the potential of the simulation procedure presented for comparative calculation of reaction rates and an improved understanding of activated states. PMID- 29466664 TI - Fixed-Node, Importance-Sampling Diffusion Monte Carlo for Vibrational Structure with Accurate and Compact Trial States. AB - We present a new approach to importance sampling in diffusion Monte-Carlo (DMC) simulations of vibrational excited states whereby the trial wave functions for low-energy states are incorporated into the diffusion equations so as to enforce their orthogonality. For the model systems examined here, simple variational wave functions based on the vibrational self-consistent field (VSCF) and the simplest vibrational configuration interaction (VCI) are effective in importance sampling provided that internal coordinates used in the underlying one-particle functions have been variationally optimized. The resulting model yields results comparable in accuracy to the best unguided DMC calculations without requiring an a priori choice of coordinates to specify nodal hyperplanes. PMID- 29466665 TI - Detecting and Visualizing Reaction Intermediates of Anisotropic Nanoparticle Growth. AB - This paper describes a correlative approach to detect, visualize, and characterize intermediate species during a seedless, anisotropic nanoparticle synthesis. Changes in radical concentration as a function of time were correlated in situ to the optical properties and morphology of the particles. Depending on type and concentration of reaction precursors, either one or two increases in radical production occurred, corresponding to initial particle formation and increased branch length, respectively. Thus, changes in radical intensity can be considered as an indicator of nanoparticle structure and properties. PMID- 29466666 TI - Snapshots of the Catalytic Cycle of an O2, Pyridoxal Phosphate-Dependent Hydroxylase. AB - Enzymes that catalyze hydroxylation of unactivated carbons normally contain heme and nonheme iron cofactors. By contrast, how a pyridoxal phosphate (PLP) dependent enzyme could catalyze such a hydroxylation was unknown. Here, we investigate RohP, a PLP-dependent enzyme that converts l-arginine to ( S)-4 hydroxy-2-ketoarginine. We determine that the RohP reaction consumes oxygen with stoichiometric release of H2O2. To understand this unusual chemistry, we obtain ~1.5 A resolution structures that capture intermediates along the catalytic cycle. Our data suggest that RohP carries out a four-electron oxidation and a stereospecific alkene hydration to give the ( S)-configured product. Together with our earlier studies on an O2, PLP-dependent l-arginine oxidase, our work suggests that there is a shared pathway leading to both oxidized and hydroxylated products from l-arginine. PMID- 29466667 TI - Boron Carbonyl Analogues of Hydrocarbons: An Infrared Photodissociation Spectroscopic Study of B3(CO) n+ ( n = 4-6). AB - The boron carbonyl cluster cations in the form of B3(CO) n+ ( n = 4-6) are produced and studied by infrared photodissociation spectroscopy in the carbonyl stretching frequency region in the gas phase. Their geometric structures are determined with the aid of density functional theory calculations. The B3(CO)4+ cation is characterized to have a D2 d (OC)2B?B?B(CO)2 structure and 1A1 electronic ground state with a linear boron skeleton. The B3(CO)5+ cation is determined to have a chain boron framework with C2 v symmetry. The B3(CO)6+ cation is a weakly bound CO-tagged complex involving a B3(CO)5+ ion core. Bonding analysis reveals that B3(CO)4+ has a chemical bonding pattern similar to allene, while bonding in B3(CO)5+ is similar to that in allyl anion. PMID- 29466668 TI - Quantitative Analysis of Glucose Metabolic Cleavage in Glucose Transporters Overexpressed Cancer Cells by Target-Specific Fluorescent Gold Nanoclusters. AB - The glucose metabolism rate in cancer cells is a crucial piece of information for the cancer aggressiveness. A feasible method to monitor processes of oncogenic mutations has been demonstrated in this work. The fluorescent gold nanoclusters conjugated with glucose (glucose-AuNCs) were successfully synthesized as a cancer targeting probe for glucose transporters (Gluts) overexpressed by U-87 MG cancer cells, which can be observed under confocal microscopy. The structural and optical characterizations of fluorescent glucose-AuNCs were confirmed by transmission electron microscope (TEM) and Fourier transform infrared spectroscopy (FTIR). The MTT assay exhibited the high biocompatibility of water soluble glucose-AuNCs for further biomedical applications. The glucose metabolic cleavage of glucose-AuNCs by glycolytic enzymes from U-87 MG cancer cell was measured by fluorescence change of glucose-AuNCs. The fluorescence change based on the integrated area under fluorescence spectra ( A t) of glucose-AuNCs was plotted as a function of different reaction time ( t) with glycolytic enzymes. The fitted curve of A t versus t showed the first-order kinetics to explain the mechanism of glucose metabolic cleavage rate of glucose-AuNCs by glycolytic enzymes. The rate constant k could be utilized to determine the glucose metabolism rate of glucose-AuNCs for the quantitative analysis of cancer aggressiveness. Our work provides a practical application of target-specific glucose-AuNCs as a fluorescence probe to analyze the glucose metabolism in Gluts overexpressed cancer cells. PMID- 29466669 TI - A Model of Uranium Uptake by Plant Roots Allowing for Root-Induced Changes in the soil. AB - We develop a model with which to study the poorly understood mechanisms of uranium (U) uptake by plants. The model is based on equations for transport and reaction of U and acids and bases in the rhizosphere around cylindrical plant roots. It allows for the speciation of U with hydroxyl, carbonate, and organic ligands in the soil solution; the nature and kinetics of sorption reactions with the soil solid; and the effects of root-induced changes in rhizosphere pH. A sensitivity analysis showed the importance of soil sorption and speciation parameters as influenced by pH and CO2 pressure; and of root geometry and root induced acid-base changes linked to the form of nitrogen taken up by the root. The root absorbing coefficient for U, relating influx to the concentration of U species in solution at the root surface, was also important. Simplified empirical models of U uptake by different plant species and soil types need to account for these effects. PMID- 29466670 TI - Long noncoding RNA HOTAIR mediates the estrogen-induced metastasis of endometrial cancer cells via the miR-646/NPM1 axis. AB - LncRNA homeobox (HOX) transcript antisense intergenic RNA (HOTAIR) has been confirmed to be involved in the tumorigenic progression of endometrial carcinoma (EC). However, the molecular mechanisms of HOTAIR in EC are not fully elucidated. The expression of HOTAIR and miR-646 in human EC tissues was determined by qRT PCR. The effect of miR-646 on EC cells was assessed by the cell viability, migration, and invasion using CCK-8 assays and transwell assays. RNA-binding protein immunoprecipitation assays and RNA pull-down assays were performed to explore the interaction between HOTAIR and miR-646. The regulation of miR-646 on nucleophosmin 1 (NPM1) was tested using luciferase reporter assays. MiR-646 expression was significantly decreased both in human EC tissues ( n = 23) and cell lines (Ishikawa and HEC-1-A) compared with the control. Moreover, miR-646 expression was negatively related to HOTAIR in human EC tissues ( n = 23). Our results also showed that miR-646 overexpression considerably attenuated the E2 promoted viability, migration, and invasion of Ishikawa and HEC-1-A cells in vitro. In addition, HOTAIR was confirmed to regulate the viability, migration, and invasion of EC cells through negative regulating miR-646. More importantly, we also demonstrated that NPM1 was the target of miR-646, and HOTAIR promoted NPM1 expression through interacting with miR-646 in EC cells. Taken together, our findings presented that HOTAIR could regulate NPM1 via interacting with miR-646, thereby governing the viability, migration, and invasion of EC cells. PMID- 29466671 TI - Lipopolysaccharide stimulates BK channel activity in bladder umbrella cells. AB - Bladder urothelium plays an active role in response to bacterial infection. There is little known about the electrophysiological activity in urothelial cells in this process. We used a nonenzymatic method to isolate bladder urothelial tissue and to patch clamp umbrella cells in situ. A 200 pS conductance potassium (K+) channel was detected from female C57BL6 mice. Of 58 total patches, 17.2% patches displayed the 200 pS K+ conductance channel. This K+ conductance channel showed Ca2+ sensitivity and voltage dependence. Specific big-conductance potassium channel (BK) inhibitors (paxilline, iberiotoxin) blocked the 200 pS K+ conductance channel activity. RT-PCR and immunoblot confirmed BK channel pore forming alpha-subunit (BK-alpha) mRNA and protein in urothelium. Immunohistochemistry also showed the BK-alpha located in urothelium. The above data provided evidence that the 200 pS K+ conductance channel was a BK channel. Lipopolysaccharide (LPS), a component of uropathogenic Escherichia coli, was used to investigate the role of BK channel in the pathogenesis of urinary tract infection. BK channel activity as NPo increased threefold within 30 min of exposure to LPS. mRNAs for LPS receptors (TLR4, CD14, MD-2) were expressed in the urothelium but not in lamina propria or detrusor. Blockade of the receptors by an antagonist (polymyxin B) abrogated LPS's effect on BK channel. The involvement of protein kinase A (PKA) on BK channel activity was demonstrated by applying PKA blockers (H89 and PKI). Both PKA inhibitors abolished the BK channel activity induced by LPS. In conclusion, BK channel was identified in bladder umbrella cells, and its activity was significantly increased by LPS. PMID- 29466672 TI - The long noncoding RNA SNHG1 promotes nucleus pulposus cell proliferation through regulating miR-326 and CCND1. AB - Aberrant nucleus pulposus cell proliferation is implicated in the development of intervertebral disk degeneration (IDD). Recent studies have suggested that long noncoding RNAs (lncRNAs) can modulate cell proliferation in several pathological conditions. Here, we indicate that expression of SNHG1 was upregulated in IDD tissues compared with control tissues and that higher SNHG1 expression was associated with disk degeneration grade. In addition, we show that ectopic expression of SNHG1 promoted nucleus pulposus (NP) cell proliferation and increased the PCNA and cyclin D1 expression in NP cells. Ectopic expression of SNHG1 inhibited miR-326 expression in nucleus pulposus cells and promoted CCND1 expression, which is a direct target gene of SNHG1. Moreover, we demonstrate that expression of miR-326 was downregulated in IDD tissues compared with control tissues and that lower SNHG1 expression was associated with disk degeneration grade. Expression of miR-326 was negatively associated with SNHG1 expression in disk degeneration tissues. Overexpression of miR-326 inhibited NP cell growth and inhibited PCNA and cyclin D1 expression in NP cells. Furthermore, we show that overexpression of SNHG1 promoted nucleus pulposus cell proliferation through inhibiting miR-326 expression. These data shed novel light on the role of SNHG1 in the pathogenesis of IDD. PMID- 29466674 TI - Expiratory Flow Limitation Assessment in Patients with Acute Respiratory Distress Syndrome.

AB - INTRODUCTION: Alopecia Areata is a common form of non-scarring hair loss that usually starts abruptly with a very high psychological impact. Due to the still not completely understood etiopathogenesis, at present there is no treatment that can induce a permanent remission and there is no drug approved for the treatment of this disorder. Areas covered: Leading existing treatment are briefly overviewed and then ongoing research on Janus Kinases Inhibitors is discussed, reviewing trials with oral and topical formulations so as new opportunities for other forms of alopecia, such as cicatricial alopecia. Expert opinion: JAK inhibitors represent a promise among alopecia treatments, but further studies are needed on long term safety. There is still no validated dosage for alopecia areata and the vehicles used for topical formulations seem not yet ideal in terms of skin penetration and reduced systemic absorption. Hopefully several studies are ongoing and we hope, in the near future, that JAK inhibitors will become part of the armamentarium to treat alopecia areata patients in terms of safety and costs. PMID- 29466676 TI - Establishing MALDI-TOF as Versatile Drug Discovery Readout to Dissect the PTP1B Enzymatic Reaction. AB - Label-free, mass spectrometric (MS) detection is an emerging technology in the field of drug discovery. Unbiased deciphering of enzymatic reactions is a proficient advantage over conventional label-based readouts suffering from compound interference and intricate generation of tailored signal mediators. Significant evolvements of matrix-assisted laser desorption/ionization time-of flight (MALDI-TOF) MS, as well as associated liquid handling instrumentation, triggered extensive efforts in the drug discovery community to integrate the comprehensive MS readout into the high-throughput screening (HTS) portfolio. Providing speed, sensitivity, and accuracy comparable to those of conventional, label-based readouts, combined with merits of MS-based technologies, such as label-free parallelized measurement of multiple physiological components, emphasizes the advantages of MALDI-TOF for HTS approaches. Here we describe the assay development for the identification of protein tyrosine phosphatase 1B (PTP1B) inhibitors. In the context of this precious drug target, MALDI-TOF was integrated into the HTS environment and cross-compared with the well-established AlphaScreen technology. We demonstrate robust and accurate IC50 determination with high accordance to data generated by AlphaScreen. Additionally, a tailored MALDI-TOF assay was developed to monitor compound-dependent, irreversible modification of the active cysteine of PTP1B. Overall, the presented data proves the promising perspective for the integration of MALDI-TOF into drug discovery campaigns. PMID- 29466677 TI - Analysis of Graft Length Change Patterns in Medial Patellofemoral Ligament Reconstruction via a Fluoroscopic Guidance Method. AB - BACKGROUND: A fluoroscopic guidance method for medial patellofemoral ligament (MPFL) reconstruction has been widely used to determine the anatomic femoral attachment site. PURPOSE: To examine the graft length change patterns in MPFL reconstruction with a fluoroscopic guidance method. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: Forty-four knees of 42 patients who underwent MPFL reconstruction for the treatment of recurrent patellar dislocation were examined prospectively. During surgery, suture anchors were inserted into the proximal one-third and center of the patella. A guide pin for the femoral tunnel was inserted into the position reported by Schottle et al based on the true lateral view of the knee under fluoroscopic control. Changes in graft length patterns of the proximal and center anchors were examined through 0 degrees to 120 degrees of knee flexion. Favorable changes in length patterns were defined as meeting 2 of 3 criteria: (1) not long during flexion (<=3 mm between 30 degrees and 120 degrees of flexion) and either (2) nearly isometric during flexion between 0 degrees and 90 degrees or (3) slightly long during maximum extension (<=3 mm). Other patterns were considered unfavorable. If the change in length pattern was unfavorable, then the pin for the femoral tunnel was moved to different positions until it was favorable. Knees were separated into the favorable group and the unfavorable group. Differences between the groups regarding radiographic parameters were assessed. Student t test or chi-square test was used for statistical analysis. RESULTS: Of the 44 knees, 31 (70.5%) showed favorable patterns. However, 13 knees (29.5%) showed unfavorable patterns; therefore, the position of the pin was changed. The mean +/- SD distance from the original position to the final position was 5.3 +/- 1.1 mm distal for 7 patients and 5.2 +/- 0.4 mm posterodistal for 6 patients. Technical errors, including a nontrue lateral view and the tip of the wire not being in the determined area, were found for 4 of 13 knees in the unfavorable group. There was no statistical difference in radiographic parameters between the groups. CONCLUSION: The graft length change pattern could be nonphysiologic at the position determined through the fluoroscopic guidance method; thus, caution may be necessary. The change in length pattern should be checked before graft fixation. If the length change pattern is unfavorable, then it is advisable to move it approximately 5 to 7 mm distally or posterodistally from the first position. PMID- 29466678 TI - Update in Asthma 2017. PMID- 29466679 TI - A Biomechanical Comparison of Fifth Metatarsal Jones Fracture Fixation Methods. AB - BACKGROUND: Fifth metatarsal base fractures of the metaphyseal-diaphyseal watershed junction (Jones fracture) are commonly treated with surgical fixation in athletes. Intramedullary screw fixation remains the most utilized construct, although plantar-lateral plating is an alternative. Purpose/Hypothesis: The purpose was to compare the mechanical strength of fracture fixation between an intramedullary screw and plantar-lateral plating. The hypothesis was that plantar lateral plate fixation would allow for more cycles and higher peak loads before failure, as well as less fracture gapping, than would an intramedullary screw in cadaveric foot specimens with simulated Jones fractures exposed to cantilever bending. STUDY DESIGN: Controlled laboratory study. METHODS: Twelve pairs of male cadaver feet were separated into 2 groups (plate or screw) to conduct contralateral comparative testing of 2 devices with equally numbered right and left feet. For each fifth metatarsal, an osteotomy with a microsagittal saw was created to simulate a Jones fracture. The plate group underwent fixation with a 3.0-mm 4-hole low-profile titanium plate placed plantar-laterally with 3 locking screws and 1 nonlocking screw. The screw group underwent fixation with a 40- or 45-mm * 5.5-mm partially threaded solid titanium intramedullary screw. After fixation, the metatarsals were excised for biomechanical testing. Cyclic cantilever failure testing was conducted with a gradient-cycle method. Sinusoidal loading forces were applied, increasing by 5.0-pound-force increments per 10 cycles, until each specimen experienced mechanical failure of implant or bone. Failure mode, number of cycles to failure, peak failure load, gap width at the last mutual prefailure loading, and video data were recorded. Paired 2-tailed t test (alpha = 0.05) was used to compare groups ( P < .05 set for significance). RESULTS: Failure mode in both groups occurred predominantly at the bone-implant interface. Plate fixation resulted in significantly higher mean +/- SD values for cycles to failure (63.9 +/- 27.0 vs 37.3 +/- 36.9, P = .01) and peak failure load (159.2 +/- 60.5 N vs 96.5 +/- 45.8 N, P = .01), with a significantly lower mean gap width (0.0 +/- 0.0 mm vs 3.2 +/- 2.4 mm, P < .01). CONCLUSION: As compared with intramedullary screw fixation, plantar-lateral plating allowed for greater cycles to failure and peak load before failure, as well as less gap width, when applied to cadaver foot specimens with simulated Jones fractures exposed to cantilever bending in a load frame. CLINICAL RELEVANCE: Early return to play among athletes before Jones fracture union is associated with increased risk of failure. This study introduces a plantar-lateral plating construct that performed more favorably than intramedullary screw fixation when applied to simulated Jones fractures in cadaveric foot specimens. Further clinical comparative studies are needed to assess the clinical use of this construct.

PMID- 29466680 TI - Cytokine Responses to Rhinovirus and Development of Asthma, Allergic Sensitization, and Respiratory Infections during Childhood. AB - RATIONALE: Immunophenotypes of antiviral responses, and their relationship with asthma, allergy, and lower respiratory tract infections, are poorly understood. OBJECTIVES: We characterized multiple cytokine responses of peripheral blood mononuclear cells to rhinovirus stimulation, and their relationship with clinical outcomes. METHODS: In a population-based birth cohort, we measured 28 cytokines after stimulation with rhinovirus-16 in 307 children aged 11 years. We used machine learning to identify patterns of cytokine responses, and related these patterns to clinical outcomes, using longitudinal models. We also ascertained phytohemagglutinin-induced T-helper cell type 2 (Th2)-cytokine responses (PHA Th2). MEASUREMENTS AND MAIN RESULTS: We identified six clusters of children based on their rhinovirus-16 responses, which were differentiated by the expression of four cytokine/chemokine groups: interferon-related (IFN), proinflammatory (Inflam), Th2-chemokine (Th2-chem), and regulatory (Reg). Clusters differed in their clinical characteristics. Children with an IFNmodInflamhighestTh2 chemhighestReghighest rhinovirus-16-induced pattern had a PHA-Th2low response, and a very low asthma risk (odds ratio [OR], 0.08; 95% confidence interval [CI], 0.01-0.81; P = 0.03). Two clusters had a high risk of asthma and allergic sensitization, but with different trajectories from infancy to adolescence. The IFNlowestInflamhighTh2-chemlowRegmod cluster exhibited a PHA-Th2lowest response and was associated with early-onset asthma and sensitization, and the highest risk of asthma exacerbations (OR, 1.37; 95% CI, 1.07-1.76; P = 0.014) and lower respiratory tract infection hospitalizations (OR, 2.40; 95% CI, 1.26-4.58; P = 0.008) throughout childhood. In contrast, the IFNhighestInflammodTh2 chemmodReghigh cluster with a rhinovirus-16-cytokine pattern was characterized by a PHA-Th2highest response, and a low prevalence of asthma/sensitization in infancy that increased sharply to become the highest among all clusters by adolescence (but with a low risk of asthma exacerbations). CONCLUSIONS: Early onset troublesome asthma with early-life sensitization, later-onset milder allergic asthma, and disease protection are each associated with different patterns of rhinovirus-induced immune responses. PMID- 29466682 TI - No effect of acute normobaric hypoxia on plasma triglyceride levels in fasting healthy men. AB - Circulating fatty acids are a major systemic energy source in the fasting state as well as a determinant of hepatic triglycerides (TG)-rich very-low-density lipoprotein production. Upon acute hypoxia, sympathetic arousal induces adipose tissue lipolysis, resulting in an increase in circulating nonesterified fatty acids (NEFA). Animal studies suggest that TG clearance may also be strongly reduced under hypoxia, though this effect has been shown to be dependent on temperature. Whether the hypoxia-induced rise in blood fatty acid concentrations affects fasting TG levels in humans under thermoneutral conditions remains unknown. TG, NEFA, and glycerol levels were measured in fasted healthy young men (n = 10) exposed for 6 h to either normoxia (ambient air) or acute hypoxia (fraction of inspired oxygen = 0.12) in a randomized, crossover design. Participants were casually clothed and rested in front of a fan in an environmental chamber maintained at 28 degrees C during each trial. Under hypoxia, a significantly greater increase in NEFA occurred (condition * time interaction, p = 0.049) and glycerol levels tended to be higher (condition * time, p = 0.104), suggesting an increase in adipose tissue lipolysis. However, plasma TG levels did not change over time and did not differ between the normoxia and hypoxia conditions. In conclusion, acute exposure to normobaric hypoxia under thermoneutral condition in healthy men during fasting state increased lipolysis without affecting circulating TG. PMID- 29466683 TI - Mechanical testing of a steel-reinforced epoxy resin bar and clamp for external skeletal fixation of long-bone fractures in cats. AB - AIMS: To provide veterinarians with confidence when using a commercially available epoxy resin in external skeletal fixators (ESF), testing was conducted to determine exothermia during curing of the epoxy resin compared to polymethylmethacrylate (PMMA), the hardness of the epoxy resin as a bar over 16 weeks, and the strength of the epoxy resin bar compared with metal clamps in similarly constructed Type 1a ESF constructs simulating the repair of feline long bone fractures. METHODS: Exothermia of the epoxy resin during curing was tested against PMMA with surface temperatures recorded over the first 15 minutes of curing, using four samples of each product. The hardness of 90 identical epoxy resin bars was tested by subjecting them to cyclic loads (1,000 cycles of 20.5 N, every 7 days) over a 16-week period and impact testing 10 bars every 2 weeks. Ten bars that were not subjected to cyclic loads were impact tested at 0 weeks and another 10 at 16 weeks. Strength of the epoxy resin product, as a bar and clamp composite, was tested against metal SK and Kirschner-Ehmer (KE) clamps and bars in Type 1a, tied-in intramedullary pin, ESF constructs with either 90 degrees or 75 degrees pin placement, subjected to compressive and bending loads to 75 N. RESULTS: The maximum temperature during curing of the epoxy resin (min 39.8, max 43.0) degrees C was less than the PMMA (min 85.2, max 98.5) degrees C (p<0.001). There was no change in hardness of the epoxy resin bars over the 16 weeks of cyclic loading (p=0.58). There were no differences between the median strength of the epoxy resin, SK or KE ESF constructs in compression or bending when tested to 75 N (p>0.05). Stiffness of constructs with 75 degrees pin placement was greater for SK than epoxy resin constructs in compression (p=0.046), and was greater for KE than epoxy resin constructs in bending (p=0.033). CONCLUSIONS: The epoxy resin tested was found to be less exothermic than PMMA; bars made from the epoxy resin showed durability over an expected fracture healing timeframe and had mechanical strength characteristics comparable to metal bar and clamp ESF constructs. CLINICAL RELEVANCE: The epoxy resin ESF construct tested in this study can be considered a suitable replacement for SK or KE ESF constructs in the treatment of feline long-bone fractures, in terms of mechanical strength. PMID- 29466684 TI - Cardiovascular response to trigeminal nerve stimulation at rest and during exercise in humans: does sex matter? AB - We sought to investigate the possibility that there are sex differences in the cardiovascular responses to trigeminal nerve stimulation (TGS) with cold exposure to the face at rest and during dynamic exercise. In 9 healthy men (age: 28 +/- 3 yr; height: 178 +/- 1 cm; weight: 77 +/- 8 kg) and 13 women (age 26 +/- 5 yr; height 164 +/- 3 cm; weight 63 +/- 7 kg) beat-to-beat heart rate (HR) and blood pressure were recorded. Mean arterial pressure (MAP), stroke volume (SV), cardiac index (CI), and total vascular resistance index (TVRI) were calculated. TGS was applied for 3 min at rest and in-between 10-min steady-state cycling exercise at a HR of 110 beats/min, the measurements were obtained during the last minute of each period. At rest, TGS increased MAP (men: Delta18 +/- 8 mmHg; women: Delta23 +/- 8 mmHg; means +/- SD), TVRI (men: Delta1.1 +/- 0.6 mmHg.l-1.min.m-2; women: Delta1.2 +/- 1.2 mmHg.l-1.min.m-2) and SV (men: Delta19 +/- 15 ml; women: Delta16 +/- 11 ml) in both groups. CI increased with TGS in women but not in men. However, men presented a bradycardic response to TGS (Delta-11 +/- 8 beats/min) that was not significant in women compared with baseline. Cycling exercise increased HR, MAP, SV, and CI and decreased TVRI in men and women. TGS during exercise further increased MAP in men and women and did not change CI in either group. SV and TVRI increased with TGS during exercise only in women. TGS during exercise evoked bradycardia in men (Delta-7 +/- 9 beats/min), whereas HR was unchanged in women. Our findings indicate sex differences in TGS-related cardiovascular responses at rest and during exercise. PMID- 29466685 TI - Prolactin regulates liver growth during postnatal development in mice. AB - The liver grows during the early postnatal period first at slower and then at faster rates than the body to achieve the adult liver-to-body weight ratio (LBW), a constant reflecting liver health. The hormone prolactin (PRL) stimulates adult liver growth and regeneration, and its levels are high in the circulation of newborn infants, but whether PRL plays a role in neonatal liver growth is unknown. Here, we show that the liver produces PRL and upregulates the PRL receptor in mice during the first 2 wk after birth, when liver growth lags behind body growth. At postnatal week 4, the production of PRL by the liver ceases coinciding with the elevation of circulating PRL and the faster liver growth that catches up with body growth. PRL receptor null mice ( Prlr-/-) show a significant decrease in the LBW at 1, 4, 6, and 10 postnatal weeks and reduced liver expression of proliferation [cyclin D1 ( Ccnd1)] and angiogenesis [platelet/endothelial cell adhesion molecule 1 ( Pecam1)] markers relative to Prlr+/+ mice. However, the LBW increases in Prlr-/- mice at postnatal week 2 concurring with the enhanced liver expression of Igf-1 and the liver upregulation and downregulation of suppressor of cytokine signaling 2 ( Socs2) and Socs3, respectively. These findings indicate that PRL acts locally and systemically to restrict and stimulate postnatal liver growth. PRL inhibits liver and body growth by attenuating growth hormone-induced Igf-1 liver expression via Socs2 and Socs3 related mechanisms. PMID- 29466686 TI - Divergent effects of cold water immersion versus active recovery on skeletal muscle fiber type and angiogenesis in young men. AB - Resistance training (RT) increases muscle fiber size and induces angiogenesis to maintain capillary density. Cold water immersion (CWI), a common postexercise recovery modality, may improve acute recovery, but it attenuates muscle hypertrophy compared with active recovery (ACT). It is unknown if CWI following RT alters muscle fiber type expression or angiogenesis. Twenty-one men strength trained for 12 wk, with either 10 min of CWI ( n = 11) or ACT ( n = 10) performed following each session. Vastus lateralis biopsies were collected at rest before and after training. Type IIx myofiber percent decreased ( P = 0.013) and type IIa myofiber percent increased with training ( P = 0.012), with no difference between groups. The number of capillaries per fiber increased from pretraining in the CWI group ( P = 0.004) but not the ACT group ( P = 0.955). Expression of myosin heavy chain genes ( MYH1 and MYH2), encoding type IIx and IIa fibers, respectively, decreased in the ACT group, whereas MYH7 (encoding type I fibers) increased in the ACT group versus CWI ( P = 0.004). Myosin heavy chain IIa protein increased with training ( P = 0.012) with no difference between groups. The proangiogenic vascular endothelial growth factor protein decreased posttraining in the ACT group versus CWI ( P < 0.001), whereas antiangiogenic Sprouty-related, EVH1 domain-containing protein 1 protein increased with training in both groups ( P = 0.015). Expression of microRNAs that regulate muscle fiber type (miR-208b and 499a) and angiogenesis (miR-15a, -16, and -126) increased only in the ACT group ( P < 0.05). CWI recovery after each training session altered the angiogenic and fiber type-specific response to RT through regulation at the levels of microRNA, gene, and protein expression. PMID- 29466687 TI - The 2018 New Investigator Review Awards. PMID- 29466688 TI - The Efficacy of Platelet-Rich Plasma and Platelet-Rich Fibrin in Arthroscopic Rotator Cuff Repair: A Meta-analysis of Randomized Controlled Trials. AB - BACKGROUND: Basic science studies suggest that platelet-rich therapies have a positive effect on tendon repair. However, the clinical evidence is conflicted on whether this translates to increased tendon healing and improved functional outcomes. PURPOSE: To perform a systematic review of randomized controlled trials (RCTs) in the literature to ascertain whether platelet-rich plasma (PRP) or platelet-rich fibrin (PRF) improved patient outcomes in arthroscopic rotator cuff repair. STUDY DESIGN: Meta-analysis. METHODS: Two independent reviewers performed the literature search based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, with a third author resolving any discrepancies. RCTs comparing PRP or PRF to a control in rotator cuff repair were included. Quality of evidence was assessed using the Jadad score. Clinical outcomes were compared using the risk ratio for dichotomous variables and the mean difference for continuous variables. A P value <.05 was deemed statistically significant. RESULTS: Eighteen RCTs with 1147 patients were included in this review. PRP resulted in significantly decreased rates of incomplete tendon healing for all tears combined (17.2% vs 30.5%, respectively; P < .05), incomplete tendon healing in small-medium tears (22.4% vs 38.3%, respectively; P < .05), and incomplete tendon healing in medium-large tears (12.3% vs 30.5%, respectively; P < .05) compared to the control. There was a significant result in favor of PRP for the Constant score (85.6 vs 83.1, respectively; P < .05) and the visual analog scale score for pain at 30 days postoperatively (2.9 vs 4.3, respectively; P < .05) and at final follow-up (1.2 vs 1.4, respectively; P < .05) compared to the control. PRF did not result in a significantly decreased rate of incomplete tendon healing for all tears combined (23.0% vs 24.6%, respectively; P = .74) or an improved Constant score (80.8 vs 79.8, respectively; P = .27) compared to the control. PRF resulted in a significantly longer operation time (99.1 vs 83.3 minutes, respectively; P< .05) compared to the control. CONCLUSION: The current evidence indicates that the use of PRP in rotator cuff repair results in improved healing rates, pain levels, and functional outcomes. In contrast, PRF has been shown to have no benefit in improving tendon healing rates or functional outcomes. PMID- 29466689 TI - The protective effects of gonadotropin-releasing hormone agonist on ovarian functions in breast Cancer patients receiving chemotherapy. AB - In recent decades, the incidence rate of breast cancer has increased dramatically worldwide and has become one of the most prevalent cancers in women. According to the global data provided by the WHO, there were more than 1.7 million new cases of breast cancer in 2012, accounting for 25% of all reported cancer cases and 15% of all reported deaths among females. To most young patients, especially those younger than 40 years of age, chemotherapy should be taken into consideration as a treatment modality, even if the tumor size is small or without lymphatic metastasis. A significant portion of the patients will suffer from the side effects that result from long-term chemotherapy regimens, such as myelosuppression, heart failure, and development of a second primary malignancy. Ovarian suppression and premature ovarian failure (POF) are the most common side effects reported as they have notable clinical symptoms; the incidence rates have been reported to be in a range of 10-90%. Gonadotropin-releasing hormone agonists (GnRH-a), also termed luteinizing hormone release hormone agonists (LHRH-a), may very well offer a solution to treating these side effects. This article aims to summarize advanced studies concerning protective effects of GnRH-a on ovarian functions in the setting of breast cancer under chemotherapy. PMID- 29466690 TI - Safety and efficacy of etanercept-methotrexate combination therapy in patients with rhupus: an observational study of non-glucocorticoid treatment for rheumatic diseases. AB - OBJECTIVES: To evaluate the safety and efficacy of etanercept (ETN) plus methotrexate (MTX) in patients with rhupus without using corticosteroids. METHODS: Twenty rhupus patients [meeting the criteria for both rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE)] who had never been treated with corticosteroids, DMARDs, or biological agents with a 28-joint Disease Activity Score (DAS28) >3.2 and lupus nephritis determined from histopathological specimens were enrolled. All patients were treated with MTX plus ETN, and monitored for 24 weeks of treatment. Clinical efficacy was evaluated using the DAS28 and Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K). Demographic characteristics, clinical parameters, and treatment data were analyzed at baseline (BL) and after 4, 8, 16, and 24 weeks of treatment. The incidence of adverse events (AEs) was evaluated. RESULTS: The 20 patients had a mean age of 44.3+/-8 years and a disease duration of 5.4+/-3.1 years. At week 24, treatment with ETN plus MTX resulted in a significant improvement in DAS28 (3.3+/ 0.1 vs. 6.0+/-0.1 /BL; p<0.001), tender joint count (2.9+/-0.2 vs. 10.75+/ 0.8/BL; p<0.001), swollen joint count (2.7+/-0.2 vs. 8.5+/-0.5/BL; p<0.001), Visual Analog Scale for pain (27.0+/-2.6 mm vs. 66.5+/-3.1 mm/BL; p<0.001), and SLEDAI-2K (6.30+/-0.36 vs. 13.7+/-0.48/BL; p<0.001). During the study, the most frequent AEs were upper respiratory tract infections (10%), injection site reactions (10%), and cutaneous rashes (5%); there were no serious AEs. No deaths, malignancies, or tuberculosis or other serious infections were reported. CONCLUSION: Without corticosteroids, combination therapy of ETN plus MTX was relatively safe and effective in rhupus patients, which indicates efficacy of non corticosteroid treatment for rhupus. PMID- 29466691 TI - Role of production of type I interferons by B cells in the mechanisms and pathogenesis of systemic lupus erythematosus. AB - Type I interferons (IFNs) have a prominent role in many aspects of normal innate and adaptive immunity and autoimmunity. However, cell-type specific information about type I IFN expression and autocrine/paracrine signaling is sparse and mostly focused on non-lymphocyte and non-immune cell populations. A major function of B cells is cytokine production, but surprisingly, type I IFN production by B cells in systemic lupus erythematosus (SLE) has not been thoroughly investigated. This is due, in part, to the established view that plasmacytoid dendritic cells (pDCs) are the primary source of pathogenic type I IFN in lupus. Recent studies, however, have provided evidence to challenge this paradigm. Here, we discuss data supporting a new concept that the production of type I IFN, especially IFNbeta, by early stage transitional B cells may be an important source of type I IFN to support autoreactive B cell development in lupus. These findings, if confirmed, may provide a new paradigm in designing and developing more effective therapies for preventing the formation of autoreactive B cells. PMID- 29466692 TI - Anti-programmed cell death-1 (PD-1) monoclonal antibodies in treating advanced melanoma -- a clinical update. AB - Since their approval by regulatory agencies worldwide, the anti-PD-1 monoclonal antibodies (mAbs), as monotherapy or in combination with ipilimumab, have become the standard frontline therapy for advanced BRAF-wild-type melanoma and an eminent rival to targeted therapy in the first-line setting for unresectable BRAF mutated melanoma. Mature survival data from randomized phase 3 trials have emerged, confirming their position in the current treatment schema for advanced melanoma. Recently, the clinical utility of anti-PD-1 agents has extended into other disease settings, such as resected high-risk melanomas, non-cutaneous subtypes, and brain metastases. How to best combat resistance to anti-PD-1 mAbs remains the major focus of clinical investigations. This review aims to provide an update on the recent progress and current challenges relating to the clinical application of anti-PD-1 agents in the treatment of advanced melanoma. PMID- 29466693 TI - Acute extracellular matrix, inflammatory and MAPK response to lengthening contractions in elderly human skeletal muscle. AB - To uncover potential factors that may be involved in the impaired regenerative capacity of aged skeletal muscle, we comprehensively assessed the molecular stress response following muscle damage in old and young individuals. 10 young (22.7 +/- 2.25 yrs) and 8 physically active old (70.9 +/- 7.5 yrs) subjects completed a bout of 300 lengthening contractions (LC), and muscle biopsies were taken pre-exercise and at 3, 24, and 72 h post-LC. Both age groups performed the same amount of work during LC, with the old group displaying a resistance to LC induced fatigue during the exercise. Muscle damage was evident by soreness and losses in isokinetic force and power production, though older subjects experienced reduced force and power losses relative to the young group. The acute extracellular matrix (ECM) response was characterized by substantial increases in the glycoproteins tenascin C and fibronectin in the young, which were blunted in the old muscle following damage. Old muscle displayed a generally heightened and asynchronous inflammatory response compared to young muscle, with higher expression of MCP-1 that appeared at later time points, and increased NF-kappab activity. Expression of the stress-related MAPKs P38 and JNK increased only in the old groups following muscle damage. In summary, aberrations appear in the inflammatory, ECM and MAPK responses of aged skeletal muscle following damaging LC, each of which may individually or collectively contribute to the deterioration of muscle repair mechanisms that accompanies aging. PMID- 29466694 TI - Lipid pathway deregulation in advanced prostate cancer. AB - The link between prostate cancer (PC) development and lipid metabolism is well established, with AR intimately involved in a number of lipogenic processes involving SREBP1, PPARG, FASN, ACC, ACLY and SCD1. Recently, there is growing evidence implicating the role of obesity and peri-prostatic adipose tissue (PPAT) in PC aggressiveness and related mortality, suggesting the importance of lipid pathways in both localised and disseminated disease. A number of promising agents are in development to target the lipogenic axis in PC, and the likelihood is that these agents will form part of combination drug strategies, with targeting of multiple metabolic pathways (e.g. FASN and CPT1), or in combination with AR pathway inhibitors (SCD1 and AR). PMID- 29466695 TI - Molecular mechanisms and therapeutic targets in neuroblastoma. AB - Neuroblastoma is the most common extracranical tumor of childhood and the most deadly tumor of infancy. It is characterized by early age onset and high frequencies of metastatic disease but also the capacity to spontaneously regress. Despite intensive therapy, the survival for patients with high-risk neuroblastoma and those with recurrent or relapsed disease is low. Hence, there is an urgent need to develop new therapies for these patient groups. The molecular pathogenesis based on high-throughput omics technologies of neuroblastoma is beginning to be resolved which have given the opportunity to develop personalized therapies for high-risk patients. Here we discuss the potential of developing targeted therapies against aberrantly expressed molecules detected in sub populations of neuroblastoma patients and how these selected targets can be drugged in order to overcome treatment resistance, improve survival and quality of life for these patients and also the possibilities to transfer preclinical research into clinical testing. PMID- 29466696 TI - UHRF1 regulates CDH1 via promoter associated non-coding RNAs in prostate cancer cells. AB - Non-coding RNAs (ncRNAs) transcribed from the promoter and the downstream region can affect the expression of the corresponding coding genes. It has been shown that sense-directed ncRNAs arising from the promoter region of the E-cadherin gene (CDH1) mediate its repression. Here, we show that an antisense-directed ncRNA (paRCDH1-AS) transcribed from the CDH1 promoter is necessary for its expression. paRCDH1-AS acts as a hooking scaffold by recruiting the epigenetic regulators, UHRF1, DNMT3A, SUV39H1 and SUZ12, involved in CDH1 repression. The binding of epigenetic regulators to paCRDH1-AS, indeed, prevents their localization to the chromatin on CDH1 promoter. Moreover, paRCDH1-AS silencing induces CDH1 repression and a switch of the epigenetic profile on the promoter towards a more closed chromatin. Using bioinformatic and experimental approaches we defined that the promoter of the paRCDH1-AS is shared with the E-cadherin gene, showing a bidirectional promoter activity. We found that UHRF1 controls both CDH1 and paRCDH1-AS by directly binding this bidirectional promoter region. Our study provides evidences, for the first time, that UHRF1 recruitment can be affected by promoter-associated non-coding RNAs, opening new perspective regarding the role of UHRF1 in these complex regulatory networks. PMID- 29466697 TI - Cdk-related kinase 9 regulates RNA polymerase II mediated transcription in Toxoplasma gondii. AB - Cyclin-dependent kinases are an essential part of eukaryotic transcriptional machinery. In Apicomplexan parasites, the role and relevance of the kinases in the multistep process of transcription seeks more attention given the absence of full repertoire of canonical Cdks and cognate cyclin partners. In this study, we functionally characterize T. gondii Cdk-related kinase 9 (TgCrk9) showing maximal homology to eukaryotic Cdk9. An uncanonical cyclin, TgCyclin L, colocalizes with TgCrk9 in the parasite nucleus and co-immunoprecipitate, could activate the kinase in-vitro. We identify two threonines in conserved T-loop domain of TgCrk9 that are important for its activity. The activated TgCrk9 phosphorylates C terminal domain (CTD) of TgRpb1, the largest subunit of RNA polymerase II highlighting its role in transcription. Selective chemical inhibition of TgCrk9 affected serine 2 phosphorylation in the heptapeptide repeats of TgRpb1-CTD towards 3' end of genes consistent with a possible role in transcription elongation. Interestingly, TgCrk9 kinase activity is regulated by the upstream TgCrk7 based CAK complex. TgCrk9 was found to functionally complement the role of its yeast counterpart Bur1 establishing its role as an important transcriptional kinase. In this study, we provide robust evidence that TgCrk9 is an important part of transcription machinery regulating gene expression in T. gondii. PMID- 29466699 TI - Unveiling network-based functional features through integration of gene expression into protein networks. AB - Decoding health and disease phenotypes is one of the fundamental objectives in biomedicine. Whereas high-throughput omics approaches are available, it is evident that any single omics approach might not be adequate to capture the complexity of phenotypes. Therefore, integrated multi-omics approaches have been used to unravel genotype-phenotype relationships such as global regulatory mechanisms and complex metabolic networks in different eukaryotic organisms. Some of the progress and challenges associated with integrated omics studies have been reviewed previously in comprehensive studies. In this work, we highlight and review the progress, challenges and advantages associated with emerging approaches, integrating gene expression and protein-protein interaction networks to unravel network-based functional features. This includes identifying disease related genes, gene prioritization, clustering protein interactions, developing the modules, extract active subnetworks and static protein complexes or dynamic/temporal protein complexes. We also discuss how these approaches contribute to our understanding of the biology of complex traits and diseases.

PMID- 29466698 TI - ERK1/2/mTOR/Stat3 pathway-mediated autophagy alleviates traumatic brain injury induced acute lung injury. AB - Acute lung injury (ALI) is one of several complications in patients with traumatic brain injury (TBI). Autophagy is a primary homeostatic process that promotes cell survival under stress. Accumulating evidence implicates autophagy in the pathogenesis of ALI under various conditions. However, the role of autophagy in TBI-induced ALI remains unknown. The aim of this study was to adjust autophagy with pharmacological agents to determine its functional significance in TBI-induced ALI. Rats were preconditioned with autophagy promoter rapamycin or inhibitor 3-methyladenine before they were challenged with TBI. Extracellular signal-regulated kinase 1/2 (ERK1/2) inhibitor U0126, mechanistic target of rapamycin (mTOR) inhibitor rapamycin, and signal transducer and activator of transcription 3 (Stat3) inhibitor S31-201 were used to test the role of ERK1/2/mTOR/Stat3 signaling pathway in regulating autophagy. Autophagy is activated in lung tissues after TBI. Enhancement of autophagy suppressed apoptosis, inflammation and oxidative stress in lung tissues, which were activated after TBI, whereas inhibition of autophagy aggravated these critical pathological changes. Autophagy also improved TBI-induced impairment in pulmonary barrier function, oxygenation function and static compliance. Furthermore, TBI induced autophagy was mediated by ERK1/2/mTOR/Stat3 pathway, which may serve to reduce ALI and improve pulmonary barrier function, oxygenation function and static compliance. These findings are important for the prevention and treatment of TBI-induced ALI. PMID- 29466700 TI - Engineering of new-to-nature halogenated indigo precursors in plants. AB - Plants are versatile chemists producing a tremendous variety of specialized compounds. Here, we describe the engineering of entirely novel metabolic pathways in planta enabling generation of halogenated indigo precursors as non-natural plant products. Indican (indolyl-beta-D-glucopyranoside) is a secondary metabolite characteristic of a number of dyers plants. Its deglucosylation and subsequent oxidative dimerization leads to the blue dye, indigo. Halogenated indican derivatives are commonly used as detection reagents in histochemical and molecular biology applications; their production, however, relies largely on chemical synthesis. To attain the de novo biosynthesis in a plant-based system devoid of indican, we employed a sequence of enzymes from diverse sources, including three microbial tryptophan halogenases substituting the amino acid at either C5, C6, or C7 of the indole moiety. Subsequent processing of the halotryptophan by bacterial tryptophanase TnaA in concert with a mutant of the human cytochrome P450 monooxygenase 2A6 and glycosylation of the resulting indoxyl derivatives by an endogenous tobacco glucosyltransferase yielded corresponding haloindican variants in transiently transformed Nicotiana benthamiana plants. Accumulation levels were highest when the 5-halogenase PyrH was utilized, reaching 0.93 +/- 0.089 mg/g dry weight of 5-chloroindican. The identity of the latter was unambiguously confirmed by NMR analysis. Moreover, our combinatorial approach, facilitated by the modular assembly capabilities of the GoldenBraid cloning system and inspired by the unique compartmentation of plant cells, afforded testing a number of alternative subcellular localizations for pathway design. In consequence, chloroplasts were validated as functional biosynthetic venues for haloindican, with the requisite reducing augmentation of the halogenases as well as the cytochrome P450 monooxygenase fulfilled by catalytic systems native to the organelle. Thus, our study puts forward a viable alternative production platform for halogenated fine chemicals, eschewing reliance on fossil fuel resources and toxic chemicals. We further contend that in planta generation of halogenated indigoid precursors previously unknown to nature offers an extended view on and, indeed, pushes forward the established frontiers of biosynthetic capacity of plants. PMID- 29466701 TI - Interaction between amyloidogenic proteins and biomembranes in protein misfolding diseases: Mechanisms, contributors, and therapy. AB - The toxic deposition of misfolded amyloidogenic proteins is associated with more than fifty protein misfolding diseases (PMDs), including Alzheimer's disease, Parkinson's disease and type 2 diabetes mellitus. Protein deposition is a multi step process modulated by a variety of factors, in particular by membrane-protein interaction. The interaction results in permeabilization of biomembranes contributing to the cytotoxicity that leads to PMDs. Different biological and physiochemical factors, such as protein sequence, lipid composition, and chaperones, are known to affect the membrane-protein interaction. Here, we provide a comprehensive review of the mechanisms and contributing factors of the interaction between biomembranes and amyloidogenic proteins, and a summary of the therapeutic approaches to PMDs that target this interaction. This article is part of a Special Issue entitled: Protein Aggregation and Misfolding at the Cell Membrane Interface edited by Ayyalusamy Ramamoorthy. PMID- 29466702 TI - Inflammasome biology, molecular pathology and therapeutic implications. AB - Inflammasomes are intracellular multiprotein signaling complexes, mainly present in myeloid cells. They commonly assemble around a cytoplasmic receptor of the nucleotide-binding leucine-rich repeat containing receptor (NLR) family, although other cytoplasmic receptors like pyrin have been shown to form inflammasomes. The nucleation of the multiprotein scaffolding platform occurs upon detection of a microbial, a danger or a homeostasis pattern by the receptor that will, most commonly, associate with the adaptor protein ASC (apoptosis-associated speck-like protein containing a CARD) through homotypic domain interactions resulting in recruitment of procaspase-1. This will lead to the autoproteolytic activation of caspase-1, which regulates the secretion of proinflammatory IL1beta and IL18 cytokines and pyroptosis, a caspase-1-mediated form of cell death. Pyroptosis occurs through cleavage of Gasdermin D, a membrane pore forming protein. Recently, non-canonical inflammasomes have been described, which directly sense intracellular pathogens through caspase-4 and -5 in humans, leading to pyroptosis. Inflammasomes are important in host defense; however, a deregulated activity is associated with a number of inflammatory, immune and metabolic disorders. Furthermore, mutations in inflammasome receptor coding genes are causal for an increasing number of rare autoinflammatory diseases. Biotherapies targeting the products of inflammasome activation as well as molecules that directly or indirectly inhibit inflammasome nucleation and activation are promising therapeutic areas. This review discusses recent advances in inflammasome biology, the molecular pathology of several inflammasomes, and current therapeutic approaches in autoinflammatory diseases and in selected common multifactorial inflammasome-mediated disorders. PMID- 29466703 TI - sAPPbeta and sAPPalpha increase structural complexity and E/I input ratio in primary hippocampal neurons and alter Ca2+ homeostasis and CREB1-signaling. AB - One major pathophysiological hallmark of Alzheimer's disease (AD) is senile plaques composed of amyloid beta (Abeta). In the amyloidogenic pathway, cleavage of the amyloid precursor protein (APP) is shifted towards Abeta production and soluble APPbeta (sAPPbeta) levels. Abeta is known to impair synaptic function; however, much less is known about the physiological functions of sAPPbeta. The neurotrophic properties of sAPPalpha, derived from the non-amyloidogenic pathway of APP cleavage, are well-established, whereas only a few, conflicting studies on sAPPbeta exist. The intracellular pathways of sAPPbeta are largely unknown. Since sAPPbeta is generated alongside Abeta by beta-secretase (BACE1) cleavage, we tested the hypothesis that sAPPbeta effects differ from sAPPalpha effects as a neurotrophic factor. We therefore performed a head-to-head comparison of both mammalian recombinant peptides in developing primary hippocampal neurons (PHN). We found that sAPPalpha significantly increases axon length (p = 0.0002) and that both sAPPalpha and sAPPbeta increase neurite number (p < 0.0001) of PHN at 7 days in culture (DIV7) but not at DIV4. Moreover, both sAPPalpha- and sAPPbeta-treated neurons showed a higher neuritic complexity in Sholl analysis. The number of glutamatergic synapses (p < 0.0001), as well as layer thickness of postsynaptic densities (PSDs), were significantly increased, and GABAergic synapses decreased upon sAPP overexpression in PHN. Furthermore, we showed that sAPPalpha enhances ERK and CREB1 phosphorylation upon glutamate stimulation at DIV7, but not DIV4 or DIV14. These neurotrophic effects are further associated with increased glutamate sensitivity and CREB1-signaling. Finally, we found that sAPPalpha levels are significantly reduced in brain homogenates of AD patients compared to control subjects. Taken together, our data indicate critical stage-dependent roles of sAPPs in the developing glutamatergic system in vitro, which might help to understand deleterious consequences of altered APP shedding in AD patients, beyond Abeta pathophysiology. PMID- 29466704 TI - A robust SSFP technique for fMRI at ultra-high field strengths. AB - A non-balanced (nb) SSFP-based fMRI method based on CE-FAST is presented to alleviate some shortcomings of high spatial-specificity techniques commonly used in high static magnetic fields. The proposed sequence does not suffer from the banding artifacts inherent to balanced (b) SSFP, has low geometrical distortions and SAR compared to spin-echo EPI, and in contrast to previous nbSSFP implementations, is applied at a TR, theoretically prescribed for the optimum contrast. Its non-balanced gradient was chosen to just dephase the unwanted signal component (2pi dephasing per TR per voxel). 3D data were acquired from nine healthy subjects, who performed a visual-motor task on a 7 Tesla scanner. For comparison, experiments were accompanied by similar bSSFP and spin-echo acquisitions. Consistent activation was achieved in all subjects with theoretically optimal TR, in contrast to previous nbSSFP techniques. The signal stability as well as relative and absolute functional signal changes, were found to be comparable with bSSFP and spin-echo techniques. The results suggest that with suitable modifications, CE-FAST can be regarded as a robust SSFP-based method for high spatial specificity fMRI techniques. PMID- 29466705 TI - Synonymous Mutations at the Beginning of the Influenza A Virus Hemagglutinin Gene Impact Experimental Fitness. AB - The fitness effects of synonymous mutations can provide insights into biological and evolutionary mechanisms. We analyzed the experimental fitness effects of all single-nucleotide mutations, including synonymous substitutions, at the beginning of the influenza A virus hemagglutinin (HA) gene. Many synonymous substitutions were deleterious both in bulk competition and for individually isolated clones. Investigating protein and RNA levels of a subset of individually expressed HA variants revealed that multiple biochemical properties contribute to the observed experimental fitness effects. Our results indicate that a structural element in the HA segment viral RNA may influence fitness. Examination of naturally evolved sequences in human hosts indicates a preference for the unfolded state of this structural element compared to that found in swine hosts. Our overall results reveal that synonymous mutations may have greater fitness consequences than indicated by simple models of sequence conservation, and we discuss the implications of this finding for commonly used evolutionary tests and analyses. PMID- 29466706 TI - Identification and characterization of Taenia solium enolase as a plasminogen binding protein. AB - The larval stage of Taenia solium (cysticerci) is the causal agent of human and swine cysticercosis. When ingested by the host, T. solium eggs are activated and hatch in the intestine, releasing oncospheres that migrate to various tissues and evolve into cysticerci. Plasminogen (Plg) receptor proteins have been reported to play a role in migration processes for several pathogens. This work is aimed to identify Plg-binding proteins in T. solium cysticerci and determine whether T. solium recombinant enolase (rTsEnoA) is capable of specifically binding and activating human Plg. To identify Plg-binding proteins, a 2D-SDS-PAGE ligand blotting was performed, and recognized spots were identified by MS/MS. Seven proteins from T. solium cysticerci were found capable of binding Plg: fascicilin 1, fasciclin-2, enolase, MAPK, annexin, actin, and cytosolic malate dehydrogenase. To determine whether rTsEnoA binds human Plg, a ligand blotting was performed and the results were confirmed by ELISA both in the presence and absence of epsilonACA, a competitive Plg inhibitor. Finally, rTsEnoA-bound Plg was activated to plasmin in the presence of tPA. To better understand the evolution of enolase isoforms in T. solium, a phylogenetic inference analysis including 75 enolase amino acid sequences was conducted. The origin of flatworm enolase isoforms, except for Eno4, is independent of their vertebrate counterparts. Therefore, herein we propose to designate tapeworm protein isoforms as A, B, C, and 4. In conclusion, recombinant enolase showed a strong plasminogen binding and activating activity in vitro. T. solium enolase could play a role in parasite invasion along with other plasminogen-binding proteins. PMID- 29466708 TI - GNIP1 E3 ubiquitin ligase is a novel player in regulating glycogen metabolism in skeletal muscle. AB - BACKGROUND: Glycogenin-interacting protein 1 (GNIP1) is a tripartite motif (TRIM) protein with E3 ubiquitin ligase activity that interacts with glycogenin. These data suggest that GNIP1 could play a major role in the control of glycogen metabolism. However, direct evidence based on functional analysis remains to be obtained. OBJECTIVES: The aim of this study was 1) to define the expression pattern of glycogenin-interacting protein/Tripartite motif containing protein 7 (GNIP/TRIM7) isoforms in humans, 2) to test their ubiquitin E3 ligase activity, and 3) to analyze the functional effects of GNIP1 on muscle glucose/glycogen metabolism both in human cultured cells and in vivo in mice. RESULTS: We show that GNIP1 was the most abundant GNIP/TRIM7 isoform in human skeletal muscle, whereas in cardiac muscle only TRIM7 was expressed. GNIP1 and TRIM7 had autoubiquitination activity in vitro and were localized in the Golgi apparatus and cytosol respectively in LHCN-M2 myoblasts. GNIP1 overexpression increased glucose uptake in LHCN-M2 myotubes. Overexpression of GNIP1 in mouse muscle in vivo increased glycogen content, glycogen synthase (GS) activity and phospho-GSK 3alpha/beta (Ser21/9) and phospho-Akt (Ser473) content, whereas decreased GS phosphorylation in Ser640. These modifications led to decreased blood glucose levels, lactate levels and body weight, without changing whole-body insulin or glucose tolerance in mouse. CONCLUSION: GNIP1 is an ubiquitin ligase with a markedly glycogenic effect in skeletal muscle. PMID- 29466707 TI - Iron transport kinetics through blood-brain barrier endothelial cells. AB - BACKGROUND: Transferrin and its receptors play an important role during the uptake and transcytosis of iron through blood-brain barrier (BBB) endothelial cells (ECs) to maintain iron homeostasis in BBB endothelium and brain. Any disruptions in the cell environment may change the distribution of transferrin receptors on the cell surface, which eventually alter the homeostasis and initiate neurodegenerative disorders. In this paper, we developed a comprehensive mathematical model that considers the necessary kinetics for holo-transferrin internalization and acidification, apo-transferrin recycling, and exocytosis of free iron and transferrin-bound iron through basolateral side of BBB ECs. METHODS: Ordinary differential equations are formulated based on the first order reaction kinetics to model the iron transport considering their interactions with transferrin and transferrin receptors. Unknown kinetics rate constants are determined from experimental data by applying a non-linear optimization technique. RESULTS: Using the estimated kinetic rate constants, the presented model can effectively reproduce the experimental data of iron transports through BBB ECs for many in-vitro studies. Model results also suggest that the BBB ECs can regulate the extent of the two possible iron transport pathways (free and transferrin-bound iron) by controlling the receptor expression, internalization of holo-transferrin-receptor complexes and acidification of holo-transferrin inside the cell endosomes. CONCLUSION: The comprehensive mathematical model described here can predict the iron transport through BBB ECs considering various possible routes from blood side to brain side. The model can also predict the transferrin and iron transport behavior in iron-enriched and iron-depleted cells, which has not been addressed in previous work. PMID- 29466709 TI - Gastrointestinal hormones in regulation of memory. AB - The connection between the gastrointestinal hormones and the brain has been established many years ago. This relation is termed the gut-brain axis (GBA). The GBA is a bidirectional communication which not only regulates gastrointestinal homeostasis but is also linked with higher emotional and cognitive functions. Hypothalamus plays a critical role in the regulation of energy metabolism, nutrient partitioning and control of feeding behaviors. Various gut hormones are released inside the gastrointestinal tract on food intake. These hormones act peripherally and influence the different responses of the tissues to the food intake, but do also have effects on the brain. The hypothalamus, in turn, integrates visceral function with limbic system structures such as hippocampus, amygdala, and cerebral cortex. The hippocampus has been known for its involvement in the cognitive function and the modulation of synaptic plasticity. This review aims to establish the role of various gut hormones in learning and memory, through the interaction of various receptors in the hippocampus. Understanding their role in memory can also aid in finding novel therapeutic strategies for the treatment of the neurological disorders associated with memory dysfunctions. PMID- 29466710 TI - Low shear stress induces vascular eNOS uncoupling via autophagy-mediated eNOS phosphorylation. AB - Uncoupled endothelial nitric oxide synthase (eNOS) produces O2- instead of nitric oxide (NO). Earlier, we reported rapamycin, an autophagy inducer and inhibitor of cellular proliferation, attenuated low shear stress (SS) induced O2- production. Nevertheless, it is unclear whether autophagy plays a critical role in the regulation of eNOS uncoupling. Therefore, this study aimed to investigate the modulation of autophagy on eNOS uncoupling induced by low SS exposure. We found that low SS induced endothelial O2- burst, which was accompanied by reduced NO release. Furthermore, inhibition of eNOS by L-NAME conspicuously attenuated low SS-induced O2- releasing, indicating eNOS uncoupling. Autophagy markers such as LC3 II/I ratio, amount of Beclin1, as well as ULK1/Atg1 were increased during low SS exposure, whereas autophagic degradation of p62/SQSTM1 was markedly reduced, implying impaired autophagic flux. Interestingly, low SS-induced NO reduction could be reversed by rapamycin, WYE-354 or ATG5 overexpression vector via restoration of autophagic flux, but not by N-acetylcysteine or apocynin. eNOS uncoupling might be ascribed to autophagic flux blockade because phosphorylation of eNOS Thr495 by low SS or PMA stimulation was also regulated by autophagy. In contrast, eNOS acetylation was not found to be regulated by low SS and autophagy. Notably, although low SS had no influence on eNOS Ser1177 phosphorylation, whereas boosted eNOS Ser1177 phosphorylation by rapamycin were in favor of the eNOS recoupling through restoration of autophagic flux. Taken together, we reported a novel mechanism for regulation of eNOS uncoupling by low SS via autophagy-mediated eNOS phosphorylation, which is implicated in geometrical nature of atherogenesis. PMID- 29466711 TI - Colorimetric detection of 1,5-anhydroglucitol based on graphene quantum dots and enzyme-catalyzed reaction. AB - Early diagnosis of diabetes yields significant clinical benefits. The serum level of 1,5-anhydroglucitol (1,5-AG) has been a new biochemical marker for postprandial hyperglycemia. In this study, a simple colorimetric method for 1,5 AG detection has been designed based on highly efficient peroxidase mimetic activity of GQDs and enzyme-catalyzed reaction. By the catalytic action of pyranose oxidase (PROD), the 1,5-AG was oxidized to 1,5-anhydrofuctose and H2O2. The GQDs in the presence of H2O2 exhibited highly efficient catalytic activity toward the oxidation of 3, 3', 5, 5'-tetramethylbenzidine (TMB) to a blue colored product. The influence of relevant experimental variables was optimized. A linear relationship of optical signal with the concentration of 1,5-AG in the range of 20.0-100.0MUg/mL with the regression correlation coefficient of 0.9985 was obtained which could be monitored by colorimetry detection. The limit of detection (LOD) for 1,5-AG detection was approximately 0.144MUg/mL. All in all, the proposed 1,5-AG detection system based on GQDs and PROD-catalyzed reaction showed better performances with simple operation, low-cost, higher selectivity. PMID- 29466712 TI - Dihydrolipoamide dehydrogenase from Leishmania donovani: New insights through biochemical characterization. AB - Dihydrolipoamide dehydrogenase (DLDH) regulates many crucial metabolic pathways as a multi-enzyme complex. Leishmania donovani dihydrolipoamide dehydrogenase (LdDLDH) has two variants present on two different chromosomes with very less sequence similarities. In the current study, we cloned both the variants in pET28a (+) vector and expressed in Rosetta-gami (DE3) E. coli strain. Expressed proteins were finally purified from pellets using Ni-NTA affinity chromatography. Purified enzymes were biochemically characterized and different kinetic parameters were studied. Both the variants showed maximum activity in pH range of 7.0-8.0 and temperature 50+/-5 degrees C in the physiological direction. The estimated Km for dihydrolipoamide (DLA) and NAD+ were 2.7+/-0.48mM and 171.23+/ 11.59MUM respectively for variant 1 (LdBPK291950.1). In the case of variant 2 (LdBPK323510.1), Km values for DLA and NAD+ were found to be 829.85+/-37MUM and 226+/-1.56MUM respectively. The variant 2 was more efficient in terms of activity. While both the forms of the enzymes showed diaphorase activity, variant 1 was found to be better. Sequence dissimilarities of both forms were analyzed for biological insights. PMID- 29466713 TI - Daily maternal separations during stress hyporesponsive period decrease the thresholds of panic-like behaviors to electrical stimulation of the dorsal periaqueductal gray of the adult rat. AB - The present study examined whether early life maternal separation (MS), a model of childhood separation anxiety, predisposes to panic at adulthood. For this purpose, male pups were submitted to 3-h daily maternal separations along postnatal (PN) days of either the 'stress hyporesponsive period' (SHRP) from PN4 to PN14 (MS11) or throughout lactation from PN2 to PN21 (MS20). Pups were further reunited to conscious (CM) or anesthetized (AM) mothers to assess the effect of mother-pup interaction upon reunion. Controls were subjected to brief handling (15 s) once a day throughout lactation (BH20). As adults (PN60), rats were tested for the thresholds to evoke panic-like behaviors upon electrical stimulation of dorsal periaqueductal gray matter and exposed to an elevated plus-maze, an open field, a forced swim and a sucrose preference test. A factor analysis was also performed to gain insight into the meaning of behavioral tests. MS11-CM rather than MS20-CM rats showed enhanced panic responses and reductions in both swimming and sucrose preference. Panic facilitations were less intense in mother-neglected rats. Although MS did not affect anxiety, MS11-AM showed robust reductions of defecation in an open-field. Factor analysis singled out anxiety, hedonia, exploration, coping and gut activity. Although sucrose preference and coping loaded on separate factors, appetite (adult weight) correlated with active coping in both forced swim and open-field (central area exploration). Concluding, whereas 3h-daily maternal separations during SHRP increased rat's susceptibility to experimental panic attacks, separations throughout lactation had no effects on panic and enhanced active coping. PMID- 29466714 TI - Cell wall enrichment unveils proteomic changes in the cell wall during treatment of Mycobacterium smegmatis with sub-lethal concentrations of rifampicin. AB - : Understanding the cell wall of mycobacteria is crucial for improving drug design or identifying new antigens suitable to vaccination. Yet this remains problematic due to the complexity of the cell wall composition. In this study, we successfully developed gel-free approaches to study cell wall proteins in Mycobacterium smegmatis. The cell wall was subjected to differential centrifugation, differential detergent solubilisation and phase separation to yield the genuine cell wall proteome. Next, protein extracts were digested by filter-assisted sample preparation for LC-MS/MS analysis on a Q Exactive mass spectrometer, and identified proteins filtered through a stringent bioinformatics pipeline. This yielded the unprecedented coverage of 96 lipoproteins, 475 membrane proteins and 73 secreted proteins. Employing this approach, we next quantified changes in the cell wall proteome during exposure of M. smegmatis to sub-lethal concentration of rifampicin. This facilitated detailed characterisation of the dysregulation of ABC transporters, virulence factors such as Mce proteins and PknG, and proteins involved in cell wall and lipid synthesis. Crucially, these cell wall proteins are under-represented in previous proteome analysis of M. smegmatis. This approach enables further quantitative proteomic studies of the role of the cell wall proteome of mycobacteria in virulence or during drug exposure. SIGNIFICANCE: We developed novel gel-free sample preparation workflows for the cell wall fraction of mycobacteria that significantly increase the coverage of the cell wall proteome compared to previous studies. We then provide a data analysis workflow that enables the removal of likely cytosolic contaminants in the cell wall fraction post measurement. Combined, these approaches increase the coverage of the cell wall proteome while ensuring that the identified proteins are true cell wall proteins and not carry-over of high-abundance contaminants from the cytosol. We have applied these approaches to quantify the dysregulation of cell wall proteins during exposure of M. smegmatis to rifampicin, which has shed new light on the coordinated down-regulation of ABC transporters as well as virulence factors present in the cell wall proteome. PMID- 29466715 TI - Ovine liver proteome: Assessing mechanisms of seasonal weight loss tolerance between Merino and Damara sheep. AB - : The effect of feed restriction on the liver protein profiles of two different breeds of sheep was studied. We compared Merino with the Damara, breeds with respectively low and high tolerance to nutritional stress. Each breed was grouped into two nutritional treatments: restricted (12-14% loss of live weight) and control (maintenance). The trial lasted 42 days. Animals were sacrificed and liver samples subjected to label free shotgun proteomics. The resultant proteins had both their fold change and statistical significance in an unpaired t-test calculated to identify differential protein abundance. The tool WebGestalt was utilized to perform an Overrepresentation Enrichment Analysis (ORA) for gene ontology terms associated with the significant proteins. We further validated shotgun proteomics findings using a selected reaction monitoring (SRM)-based targeted proteomics approach, where similar trends in regulation were obtained for a subset of relevant proteins across an independent cohort of animals. Results confirm that Damara has adapted to nutritional stress by mobilizing stored fatty acids within adipose tissue and converting them to energy more efficiently than Merino. Finally, Merino had an overabundance pattern primarily directed to protein synthesis pathways. Regulated proteins identified may be used as a basis for marker selection towards tolerance to nutritional stress. BIOLOGICAL SIGNIFICANCE: Sheep are one of the most important livestock animals. They remain however poorly understudied and described. Seasonal weight loss (SWL) due to pasture scarcity during the dry season is one of the most limiting conditions to ruminant production in the tropics. To counter SWL, farmers may use supplementation, expensive or difficult to implement. A more suitable long-term solution would be to use breeds that are naturally adapted to nutritional stress. This work contrasts two breeds with different levels of tolerance to SWL, the Damara and the Merino, respectively well and poorly adapted. Comparison is conducted at the level of the hepatic tissue and using label free proteomics. This work identifies a series of pathways in the liver of the Damara via label free proteomics that suggest a unique fatty acid metabolic process within this breed. Proteins that have increased abundance in the Damara in association with fatty acid metabolism may be used as potential markers of tolerance to nutritional stress. This research will pave the way for more viable, long-term solutions for farmers facing annual production problems due to drought in the tropics and the Mediterranean region. PMID- 29466716 TI - Characterization and risk assessment of seasonal and weather dynamics in organic pollutant mixtures from discharge of a separate sewer system. AB - Sites of wastewater discharge are hotspots for pollution of freshwaters with organic micropollutants and are often associated with adverse effects to aquatic organisms. The assessment, monitoring and managment of these hotspots is challenged by variations in the pollutant mixture composition due to season, weather conditions and random spills. In this study, we unraveled temporal exposure patterns in organic micropollutant mixtures from wastewater discharge and analyzed respective acute and sublethal risks for aquatic organisms. Samples were taken from two components of a separate sewer system i) a wastewater treatment plant (WWTP) and ii) a rain sewer of a medium size town as well as from the receiving river in different seasons. Rain sewer samples were separately collected for rain and dry - weather conditions. We analyzed 149 compounds by liquid chromatography-tandem mass spectrometry (LC-MS/MS). By considering the pollution dynamics in the point sources, we reduced the complexity of pollutant mixtures by k-means clustering to a few emission groups representing temporal and weather-related pollution patterns. From these groups, we derived biological quality element (BQE) - specific risk patterns. In most cases, one main risk driving emission group and a few individual risk driving compounds were identified for each BQE. While acute risk for fish was quite low, algae were exposed to seasonally emitted herbicides (terbuthylazine, spiroxamine) and crustaceans to randomly spilled insecticides (diazinon, dimethoate). Sublethal risks for all BQE were strongly influenced by constantly emitted pollutants, above all, pharmaceuticals. Variability of risks in the river was mainly driven by water discharge of the river rather than by season or peak events. Overall, the studied WWTP represented the major pollution source with a specific emission of agricultural compounds. However, the investigated rain sewer showed to be a constant pollution source due to illicit connections and was an important entry route for high loads of insecticides and biocides due to spills or incorrect disposal. By considering these pollution and risk dynamics, monitoring strategies may be optimized with a special focus on times of low flow conditions in the river, rain events and seasonally emitted risk drivers. PMID- 29466717 TI - Is bigger better? Driving factors of POTW performance in New York. AB - Like many regions around the world, New York State, USA, faces challenges in meeting wastewater treatment quality standards because of aging infrastructure, limited funding, shifting demographics and increasingly stringent environmental regulations. In recent decades construction of new wastewater treatment and distribution infrastructure in NY has most often occurred in exurban communities and suburban developments that are less dense than traditional urban cores. Here, we examine the role of size and capacity utilization on wastewater treatment effectiveness with respect to critical effluent parameters, and additionally explore which common facility engineering controls influence water quality treatment using a unique dataset of descriptive information. Our results challenge conventional wisdom, suggesting that the largest facilities (>30,000 m3/d), not the smallest (<300 m3/d), discharge TSS, BOD, and coliform at significantly higher relative effluent concentrations (i.e., the ratio of discharged concentrations to allowable limits). Capacity utilization was also positively correlated to higher concentrations of TSS, BOD, and coliform effluent concentrations in larger facilities, though those concentrations were often within regulated limits. This implies that smaller-sized facilities may perform better in terms of environmental quality, but that the largest facilities demonstrate efficiency in the sense that they are not "over-treating" wastewater while avoiding violations. Results from NY suggest that medium sized facilities (300-30,000 m3/d) are sophisticated enough to incorporate appropriate unit processes, and employ operators with sufficient training and oversight, to reach treatment outcomes that are both reliable and of high quality. PMID- 29466718 TI - The impact of dissolved oxygen on sulfate radical-induced oxidation of organic micro-pollutants: A theoretical study. AB - Sulfate radical (SO4.-)-induced oxidation is an important technology in advanced oxidation processes (AOPs) for the removal of pollutants. To date, few studies have assessed the effects of dissolved oxygen (DO) on the SO4.--induced oxidation of organic micro-pollutants. In the present work, a quantum chemical calculation was used to investigate the influence of the external oxygen molecule on the Gibbs free energy (Gpollutant) and HOMO-LUMO gap (DeltaE) of 15 organic micro pollutants representing four chemical categories. Several thermodynamic and statistical models were combined with the data from the quantum chemical calculation to illustrate the impact of DO on the oxidation of organic micro pollutants by SO4.-. Results indicated that the external oxygen molecule increased Gpollutant of all studied chemicals, which implies DO has the potential to decrease the energy barrier of the SO4.--induced oxidation and shift the chemical equilibrium of the reaction towards the side of products. From the perspective of kinetics, DO can accelerate the oxidation by decreasing DeltaE of organic micro-pollutants. In addition, changes of Gpollutant and DeltaE of the SO4.--induced oxidation were both significantly different between open-chain and aromatic chemicals, and these differences were partially attributed to the difference of polarizability of these two types of chemicals. Furthermore, we revealed that all changes of Gpollutant and DeltaE induced by DO were dependent on the DO content. Our study emphasizes the significance of DO on the oxidation of organic micro-pollutants by SO4.-, and also provides a theoretical method to study the effect of components in wastewater on removal of organic pollutants in AOPs. PMID- 29466719 TI - Simultaneous odour-face presentation strengthens hedonic evaluations and event related potential responses influenced by unpleasant odour. AB - Odours alter evaluations of concurrently presented visual stimuli, such as faces. Stimulus onset asynchrony (SOA) is known to affect evaluative priming in various sensory modalities. However, effects of SOA on odour priming of visual stimuli are not known. The present study aimed to analyse whether subjective and cortical activation changes during odour priming would vary as a function of SOA between odours and faces. Twenty-eight participants rated faces under pleasant, unpleasant, and no-odour conditions using visual analogue scales. In half of trials, faces appeared one-second after odour offset (SOA 1). In the other half of trials, faces appeared during the odour pulse (SOA 2). EEG was recorded continuously using a 128-channel system, and event-related potentials (ERPs) to face stimuli were evaluated using statistical parametric mapping (SPM). Faces presented during unpleasant-odour stimulation were rated significantly less pleasant than the same faces presented one-second after offset of the unpleasant odour. Scalp-time clusters in the late-positive-potential (LPP) time-range showed an interaction between odour and SOA effects, whereby activation was stronger for faces presented simultaneously with the unpleasant odour, compared to the same faces presented after odour offset. Our results highlight stronger unpleasant odour priming with simultaneous, compared to delayed, odour-face presentation. Such effects were represented in both behavioural and neural data. A greater cortical and subjective response during simultaneous presentation of faces and unpleasant odour may have an adaptive role, allowing for a prompt and focused behavioural reaction to a concurrent stimulus if an aversive odour would signal danger, or unwanted social interaction. PMID- 29466720 TI - Modulation of corticospinal excitability during positive and negative motor imageries. AB - We investigated corticospinal excitability during positive (execution) and negative (suppression) imageries for the right and left upper and lower limbs. In the Positive Imagery tasks, sixteen subjects were instructed to repeatedly imagine rotation of the index finger of the right or left hand, or the ankle of the right or left foot. In the Negative Imagery tasks, they were asked to imagine the suppression of movements for the index finger of the right or left hand, or the ankle of the right or left foot. A single-pulse transcranial magnetic stimulation was delivered over the left hand primary motor cortex, and motor evoked potentials (MEPs) were recorded from the right first dorsal interosseous (FDI) muscle under all conditions. The MEP amplitudes of the FDI were significantly larger in the Positive and Negative Imagery tasks than in the resting control task during motor imagery of the right hand, left hand, and left foot, but not during that of right foot. Our results indicate that imageries of suppressing hand and foot movements enhanced corticospinal excitability.

AB - Having accidental deaths from opioid overdoses almost quadrupled over the past fifteen years, there is a strong need to develop new, non-addictive medications for chronic pain to stop one of the deadliest epidemics in American history. Given their potentially fewer on-target overdosing risks and other adverse effects compared to classical opioid drugs, attention has recently shifted to opioid allosteric modulators and G protein-biased opioid agonists as likely drug candidates to prevent and/or reverse opioid overdoses. Understanding how these molecules bind and activate their receptors at an atomistic level is key to developing them into effective new therapeutics, and molecular dynamics-based strategies are contributing tremendously to this understanding. PMID- 29466722 TI - Shared and distinct regional homogeneity changes in bipolar and unipolar depression. AB - BACKGROUND: Bipolar depression (BD) is easily misdiagnosed as unipolar depression (UD) or major depressive disorder (MDD) because the depressive symptoms can overlap. Regional homogeneity (ReHo), a measure commonly used for analyzing resting-state fMRI data, has been applied to the study of various neuropsychiatric disorders. However, to date, studies directly comparing BD and UD using ReHo have been relatively scarce. Further investigation is needed to study the latent pathophysiological mechanisms of BD and UD. METHODS: Fifty-five patients with BD and 76 patients with UD, as well as 113 healthy controls (HC), underwent resting-state functional magnetic resonance imaging (fMRI). We compared the voxel-wise ReHo across the whole brain for subjects in each of the three groups. RESULTS: Significant differences were found in the left frontal cluster (LFC) across the three groups. There were differences between BD and UD in the LFC and left temporal cluster (LTC). In addition, differences between UD and HC existed in the LFC and the occipital cluster (OC). When comparing BD subjects with HC subjects, significant differences were found in all three clusters. No correlations were observed between the 17-item Hamilton Depression Rating Scale (HDRS-17) scores or sub-scores and the ReHo values of BD or UD patients. CONCLUSION: ReHo values in the LFC differed significantly among BD, UD, and HC subjects. ReHo in the LTC showed significant differences between BD and UD that might serve as neuroimaging markers of BD. Further, BD and UD shared ReHo changes in the cuneus, suggesting that the cuneus might provide a depressive state neuroimaging marker of BD and UD patients.

AB - Sirtuin 3 (SIRT3) is a NAD+-dependent deacetylase downregulated in aging and age associated diseases such as cancer and neurodegeneration and in high-fat diet (HFD)-induced metabolic disorders. Here, we performed a small-molecule screen and identified an unexpected metabolic vulnerability associated with SIRT3 loss. Azaserine, a glutamine analog, was the top compound that inhibited growth and proliferation of cells lacking SIRT3. Using stable isotope tracing of glutamine, we observed its increased incorporation into de novo nucleotide synthesis in SIRT3 knockout (KO) cells. Furthermore, we found that SIRT3 KO cells upregulated the diversion of glutamine into de novo nucleotide synthesis through hyperactive mTORC1 signaling. Overexpression of SIRT3 suppressed mTORC1 and growth in vivo in a xenograft tumor model of breast cancer. Thus, we have uncovered a metabolic vulnerability of cells with SIRT3 loss by using an unbiased small-molecule screen. PMID- 29466724 TI - BK Potassium Channels Suppress Cavalpha2delta Subunit Function to Reduce Inflammatory and Neuropathic Pain. AB - Cavalpha2delta subunits contribute to the cell-surface expression of Cav2 calcium channels. Upregulation of Cavalpha2delta-1 in dorsal root ganglion neurons occurs after nerve injury and results in an increased synaptic abundance of Cav2.2 channels in the spinal dorsal horn, thus enhancing the transmission of pain signals. Here, we report that large conductance calcium-activated potassium (BK) channels interact with the Cavalpha2delta subunit. Coexpression of BK channels with the Cav2 calcium channels reduces their cell-surface expression and whole cell current density by competing the Cavalpha2delta subunit away from the Cav2 complex. Biochemical analysis reveals that the extracellular N terminus region of the BK channel is the key molecular determinant of this effect. Intrathecally delivered virus constructs encoding a membrane-anchored BK channel N terminus peptide produces long-lasting analgesia in mouse models of inflammatory and neuropathic pain. Collectively, our data reveal an endogenous ligand of the Cavalpha2delta subunit with analgesic properties. PMID- 29466725 TI - Munc13-3 Is Required for the Developmental Localization of Ca2+ Channels to Active Zones and the Nanopositioning of Cav2.1 Near Release Sensors. AB - Spatial relationships between Cav channels and release sensors at active zones (AZs) are a major determinant of synaptic fidelity. They are regulated developmentally, but the underlying molecular mechanisms are largely unclear. Here, we show that Munc13-3 regulates the density of Cav2.1 and Cav2.2 channels, alters the localization of Cav2.1, and is required for the development of tight, nanodomain coupling at parallel-fiber AZs. We combined EGTA application and Ca2+ channel pharmacology in electrophysiological and two-photon Ca2+ imaging experiments with quantitative freeze-fracture immunoelectron microscopy and mathematical modeling. We found that a normally occurring developmental shift from release being dominated by Ca2+ influx through Cav2.1 and Cav2.2 channels with domain overlap and loose coupling (microdomains) to a nanodomain Cav2.1 to sensor coupling is impaired in Munc13-3-deficient synapses. Thus, at AZs lacking Munc13-3, release remained triggered by Cav2.1 and Cav2.2 microdomains, suggesting a critical role of Munc13-3 in the formation of release sites with calcium channel nanodomains. PMID- 29466726 TI - Tet2 Rescues Age-Related Regenerative Decline and Enhances Cognitive Function in the Adult Mouse Brain. AB - Restoring adult stem cell function provides an exciting approach for rejuvenating the aging brain. However, molecular mechanisms mediating neurogenic rejuvenation remain elusive. Here we report that the enzyme ten eleven translocation methylcytosine dioxygenase 2 (Tet2), which catalyzes the production of 5 hydroxymethylcytosine (5hmC), rescues age-related decline in adult neurogenesis and enhances cognition in mice. We detected a decrease in Tet2 expression and 5hmC levels in the aged hippocampus associated with adult neurogenesis. Mimicking an aged condition in young adults by abrogating Tet2 expression within the hippocampal neurogenic niche, or adult neural stem cells, decreased neurogenesis and impaired learning and memory. In a heterochronic parabiosis rejuvenation model, hippocampal Tet2 expression was restored. Overexpressing Tet2 in the hippocampal neurogenic niche of mature adults increased 5hmC associated with neurogenic processes, offset the precipitous age-related decline in neurogenesis, and enhanced learning and memory. Our data identify Tet2 as a key molecular mediator of neurogenic rejuvenation. PMID- 29466727 TI - In Vivo Analysis of Centromeric Proteins Reveals a Stem Cell-Specific Asymmetry and an Essential Role in Differentiated, Non-proliferating Cells. AB - Stem cells of the Drosophila midgut (ISCs) are the only mitotically dividing cells of the epithelium and, therefore, presumably the only epithelial cells that require functional kinetochores for microtubule spindle attachment during mitosis. The histone variant CENP-A marks centromeric chromatin as the site of kinetochore formation and spindle attachment during mitotic chromosome segregation. Here, we show that centromeric proteins distribute asymmetrically during ISC division. Whereas newly synthesized CENP-A is enriched in differentiating progeny, CENP-C is undetectable in these cells. Remarkably, CENP A persists in ISCs for weeks without being replaced, consistent with it being an epigenetic mark responsible for maintaining stem cell properties. Furthermore, CENP-A and its loading factor CAL1 were found to be essential for post-mitotic, differentiating cells; removal of any of these factors interferes with endoreduplication. Taken together, we propose two additional roles of CENP-A: to maintain stem cell-unique properties and to regulate post-mitotic cells. PMID- 29466728 TI - LKB1 as a Gatekeeper of Hepatocyte Proliferation and Genomic Integrity during Liver Regeneration. AB - Liver kinase B1 (LKB1) is involved in several biological processes and is a key regulator of hepatic metabolism and polarity. Here, we demonstrate that the master kinase LKB1 plays a dual role in liver regeneration, independently of its major target, AMP-activated protein kinase (AMPK). We found that the loss of hepatic Lkb1 expression promoted hepatocyte proliferation acceleration independently of metabolic/energetic balance. LKB1 regulates G0/G1 progression, specifically by controlling epidermal growth factor receptor (EGFR) signaling. Furthermore, later in regeneration, LKB1 controls mitotic fidelity. The deletion of Lkb1 results in major alterations to mitotic spindle formation along the polarity axis. Thus, LKB1 deficiency alters ploidy profile at late stages of regeneration. Our findings highlight the dual role of LKB1 in liver regeneration, as a guardian of hepatocyte proliferation and genomic integrity. PMID- 29466729 TI - A Cell-Intrinsic Interferon-like Response Links Replication Stress to Cellular Aging Caused by Progerin. AB - Hutchinson-Gilford progeria syndrome (HGPS) is a premature aging disease caused by a truncated lamin A protein (progerin) that drives cellular and organismal decline. HGPS patient-derived fibroblasts accumulate genomic instability, but its underlying mechanisms and contribution to disease remain poorly understood. Here, we show that progerin-induced replication stress (RS) drives genomic instability by eliciting replication fork (RF) stalling and nuclease-mediated degradation. Rampant RS is accompanied by upregulation of the cGAS/STING cytosolic DNA sensing pathway and activation of a robust STAT1-regulated interferon (IFN)-like response. Reducing RS and the IFN-like response, especially with calcitriol, improves the fitness of progeria cells and increases the efficiency of cellular reprogramming. Importantly, other compounds that improve HGPS phenotypes reduce RS and the IFN-like response. Our study reveals mechanisms underlying progerin toxicity, including RS-induced genomic instability and activation of IFN-like responses, and their relevance for cellular decline in HGPS. PMID- 29466730 TI - A LIN28B Tumor-Specific Transcript in Cancer. AB - The diversity and complexity of the cancer transcriptome may contain transcripts unique to the tumor environment. Here, we report a LIN28B variant, LIN28B-TST, which is specifically expressed in hepatocellular carcinoma (HCC) and many other cancer types. Expression of LIN28B-TST is associated with significantly poor prognosis in HCC patients. LIN28B-TST initiates from a de novo alternative transcription initiation site that harbors a strong promoter regulated by NFYA but not c-Myc. Demethylation of the LIN28B-TST promoter might be a prerequisite for its transcription and transcriptional regulation. LIN28B-TST encodes a protein isoform with additional N-terminal amino acids and is critical for cancer cell proliferation and tumorigenesis. Our findings reveal a mechanism of LIN28B activation in cancer and the potential utility of LIN28B-TST for clinical purposes. PMID- 29466731 TI - Spine Patterning Is Guided by Segmentation of the Notochord Sheath. AB - The spine is a segmented axial structure made of alternating vertebral bodies (centra) and intervertebral discs (IVDs) assembled around the notochord. Here, we show that, prior to centra formation, the outer epithelial cell layer of the zebrafish notochord, the sheath, segments into alternating domains corresponding to the prospective centra and IVD areas. This process occurs sequentially in an anteroposterior direction via the activation of Notch signaling in alternating segments of the sheath, which transition from cartilaginous to mineralizing domains. Subsequently, osteoblasts are recruited to the mineralized domains of the notochord sheath to form mature centra. Tissue-specific manipulation of Notch signaling in sheath cells produces notochord segmentation defects that are mirrored in the spine. Together, our findings demonstrate that notochord sheath segmentation provides a template for vertebral patterning in the zebrafish spine. PMID- 29466733 TI - Abeta Facilitates LTD at Schaffer Collateral Synapses Preferentially in the Left Hippocampus. AB - Promotion of long-term depression (LTD) mechanisms by synaptotoxic soluble oligomers of amyloid-beta (Abeta) has been proposed to underlie synaptic dysfunction in Alzheimer's disease (AD). Previously, LTD was induced by relatively non-specific electrical stimulation. Exploiting optogenetics, we studied LTD using a more physiologically diffuse spatial pattern of selective pathway activation in the rat hippocampus in vivo. This relatively sparse synaptic LTD requires both the ion channel function and GluN2B subunit of the NMDA receptor but, in contrast to electrically induced LTD, is not facilitated by boosting endogenous muscarinic acetylcholine or metabotropic glutamate 5 receptor activation. Although in the absence of Abeta, there is no evidence of hippocampal LTD asymmetry, in the presence of Abeta, the induction of LTD is preferentially enhanced in the left hippocampus in an mGluR5-dependent manner. This circuit selective disruption of synaptic plasticity by Abeta provides a route to understanding the development of aberrant brain lateralization in AD. PMID- 29466732 TI - Dissonant Representations of Visual Space in Prefrontal Cortex during Eye Movements. AB - We used local field potentials (LFPs) and spikes to investigate representations of visual space in prefrontal cortex and the dynamics of those representations during eye movements. Spatial information contained in LFPs of the frontal eye field (FEF) was differentially distributed across frequencies, with a majority of that information being carried in alpha and high-gamma bands and minimal signal in the low-gamma band. During fixation, spatial information from alpha and high gamma bands and spiking activity was robust across cortical layers. Receptive fields (RFs) derived from alpha and high-gamma bands were retinocentrically organized, and they were spatially correlated both with each other and with spiking RFs. However, alpha and high-gamma RFs probed before eye movements were dissociated. Whereas high-gamma and spiking RFs immediately converged toward the movement goal, alpha RFs remained largely unchanged during the initial probe response, but they converged later. These observations reveal possible mechanisms of dynamic spatial representations that underlie visual perception during eye movements. PMID- 29466734 TI - Pharmacological Inhibition of Necroptosis Protects from Dopaminergic Neuronal Cell Death in Parkinson's Disease Models. AB - Dysfunctions in mitochondrial dynamics and metabolism are common pathological processes associated with Parkinson's disease (PD). It was recently shown that an inherited form of PD and dementia is caused by mutations in the OPA1 gene, which encodes for a key player in mitochondrial fusion and structure. iPSC-derived neural cells from these patients exhibited severe mitochondrial fragmentation, respiration impairment, ATP deficits, and heightened oxidative stress. Reconstitution of normal levels of OPA1 in PD-derived neural cells normalized mitochondria morphology and function. OPA1-mutated neuronal cultures showed reduced survival in vitro. Intriguingly, selective inhibition of necroptosis effectively rescued this survival deficit. Additionally, dampening necroptosis in MPTP-treated mice protected from DA neuronal cell loss. This human iPSC-based model captures both early pathological events in OPA1 mutant neural cells and the beneficial effects of blocking necroptosis, highlighting this cell death process as a potential therapeutic target for PD. PMID- 29466735 TI - Noninflammatory Changes of Microglia Are Sufficient to Cause Epilepsy. AB - Microglia are well known to play a critical role in maintaining brain homeostasis. However, their role in epileptogenesis has yet to be determined. Here, we demonstrate that elevated mTOR signaling in mouse microglia leads to phenotypic changes, including an amoeboid-like morphology, increased proliferation, and robust phagocytosis activity, but without a significant induction of pro-inflammatory cytokines. We further provide evidence that these noninflammatory changes in microglia disrupt homeostasis of the CNS, leading to reduced synapse density, marked microglial infiltration into hippocampal pyramidal layers, moderate neuronal degeneration, and massive proliferation of astrocytes. Moreover, the mice thus affected develop severe early-onset spontaneous recurrent seizures (SRSs). Therefore, we have revealed an epileptogenic mechanism that is independent of the microglial inflammatory response. Our data suggest that microglia could be an opportune target for epilepsy prevention. PMID- 29466737 TI - Suppression of Tcf1 by Inflammatory Cytokines Facilitates Effector CD8 T Cell Differentiation. AB - The formation of central CD8 T cell memory in response to infection depends on the transcription factor Tcf1 (Tcf7). Tcf1 is expressed at high levels in naive CD8 T cells but downregulated in most CD8 T cells during effector differentiation. The relevance of Tcf1 downregulation for effector differentiation and the signals controlling Tcf1 expression have not been elucidated. Here, we show that systemic inflammatory signals downregulated Tcf1 in CD8 T cells during dendritic cell vaccination and bacterial infections. The suppressive effect was mediated by the inflammatory cytokine interleukin 12 (IL 12), which acted via STAT4 in CD8 T cells. IL-12-induced Tcf1 downregulation required cell cycling, occurred at the transcriptional level, and was prevented in part by inhibiting DNA methyltransferases. Absence of Tcf1 during T cell priming circumvented the need of systemic inflammation for effector differentiation. We conclude that silencing of Tcf1 by systemic inflammation facilitates effector CD8 T cell differentiation. PMID- 29466736 TI - Transcriptional Repressor HIC1 Contributes to Suppressive Function of Human Induced Regulatory T Cells. AB - Regulatory T (Treg) cells are critical in regulating the immune response. In vitro induced Treg (iTreg) cells have significant potential in clinical medicine. However, applying iTreg cells as therapeutics is complicated by the poor stability of human iTreg cells and their variable suppressive activity. Therefore, it is important to understand the molecular mechanisms of human iTreg cell specification. We identified hypermethylated in cancer 1 (HIC1) as a transcription factor upregulated early during the differentiation of human iTreg cells. Although FOXP3 expression was unaffected, HIC1 deficiency led to a considerable loss of suppression by iTreg cells with a concomitant increase in the expression of effector T cell associated genes. SNPs linked to several immune mediated disorders were enriched around HIC1 binding sites, and in vitro binding assays indicated that these SNPs may alter the binding of HIC1. Our results suggest that HIC1 is an important contributor to iTreg cell development and function. PMID- 29466738 TI - Cry2 Is Critical for Circadian Regulation of Myogenic Differentiation by Bclaf1 Mediated mRNA Stabilization of Cyclin D1 and Tmem176b. AB - Circadian rhythms regulate cell proliferation and differentiation; however, little is known about their roles in myogenic differentiation. Our synchronized differentiation studies demonstrate that myoblast proliferation and subsequent myotube formation by cell fusion occur in circadian manners. We found that one of the core regulators of circadian rhythms, Cry2, but not Cry1, is critical for the circadian patterns of these two critical steps in myogenic differentiation. This is achieved through the specific interaction between Cry2 and Bclaf1, which stabilizes mRNAs encoding cyclin D1, a G1/S phase transition regulator, and Tmem176b, a transmembrane regulator for myogenic cell fusion. Myoblasts lacking Cry2 display premature cell cycle exit and form short myotubes because of inefficient cell fusion. Consistently, muscle regeneration is impaired in Cry2-/- mice. Bclaf1 knockdown recapitulated the phenotypes of Cry2 knockdown: early cell cycle exit and inefficient cell fusion. This study uncovers a post transcriptional regulation of myogenic differentiation by circadian rhythms. PMID- 29466740 TI - TALEN-Induced Double-Strand Break Repair of CTG Trinucleotide Repeats. AB - Trinucleotide repeat expansions involving CTG/CAG triplets are responsible for several neurodegenerative disorders, including myotonic dystrophy and Huntington's disease. Because expansions trigger the disease, contracting repeat length could be a possible approach to gene therapy for these disorders. Here, we show that a TALEN-induced double-strand break was very efficient at contracting expanded CTG repeats in yeast. We show that RAD51, POL32, and DNL4 are dispensable for double-strand break repair within CTG repeats, the only required genes being RAD50, SAE2, and RAD52. Resection was totally abolished in the absence of RAD50 on both sides of the break, whereas it was reduced in a sae2Delta mutant on the side of the break containing the longest repeat tract, suggesting that secondary structures at double-strand break ends must be removed by the Mre11-Rad50 complex and Sae2. Following the TALEN double-strand break, single-strand annealing occurred between both sides of the repeat tract, leading to repeat contraction. PMID- 29466739 TI - Genetic Ablation of miR-33 Increases Food Intake, Enhances Adipose Tissue Expansion, and Promotes Obesity and Insulin Resistance. AB - While therapeutic modulation of miRNAs provides a promising approach for numerous diseases, the promiscuous nature of miRNAs raises concern over detrimental off target effects. miR-33 has emerged as a likely target for treatment of cardiovascular diseases. However, the deleterious effects of long-term anti-miR 33 therapies and predisposition of miR-33-/- mice to obesity and metabolic dysfunction exemplify the possible pitfalls of miRNA-based therapies. Our work provides an in-depth characterization of miR-33-/- mice and explores the mechanisms by which loss of miR-33 promotes insulin resistance in key metabolic tissues. Contrary to previous reports, our data do not support a direct role for SREBP-1-mediated lipid synthesis in promoting these effects. Alternatively, in adipose tissue of miR-33-/- mice, we observe increased pre-adipocyte proliferation, enhanced lipid uptake, and impaired lipolysis. Moreover, we demonstrate that the driving force behind these abnormalities is increased food intake, which can be prevented by pair feeding with wild-type animals. PMID- 29466741 TI - Rap1 Negatively Regulates the Hippo Pathway to Polarize Directional Protrusions in Collective Cell Migration. AB - In collective cell migration, directional protrusions orient cells in response to external cues, which requires coordinated polarity among the migrating cohort. However, the molecular mechanism has not been well defined. Drosophila border cells (BCs) migrate collectively and invade via the confined space between nurse cells, offering an in vivo model to examine how group polarity is organized. Here, we show that the front/back polarity of BCs requires Rap1, hyperactivation of which disrupts cluster polarity and induces misoriented protrusions and loss of asymmetry in the actin network. Conversely, hypoactive Rap1 causes fewer protrusions and cluster spinning during migration. A forward genetic screen revealed that downregulation of the Hippo (Hpo) pathway core components hpo or mats enhances the Rap1V12-induced migration defect and misdirected protrusions. Mechanistically, association of Rap1V12 with the kinase domain of Hpo suppresses its activity, which releases Hpo signaling-mediated suppression of F-actin elongation, promoting cellular protrusions in collective cell migration. PMID- 29466742 TI - Compartment-Specific Biosensors Reveal a Complementary Subcellular Distribution of Bioactive Furin and PC7. AB - Furin trafficking, and that of related proprotein convertases (PCs), may regulate which substrates are accessible for endoproteolysis, but tools to directly test this hypothesis have been lacking. Here, we develop targeted biosensors that indicate Furin activity in endosomes is 10-fold less inhibited by decanoyl-RVKR chloromethylketone and enriched >3-fold in endosomes compared to the trans-Golgi network (TGN). Endogenous PC7, which resists this inhibitor, was active in distinct vesicles. Only overexpressed PC7 activity reached the cell surface, endosomes, and the TGN. A PLC motif in the cytosolic tail of PC7 was dispensable for endosomal activity, but it was specifically required for TGN recycling and to rescue proActivin-A cleavage in Furin-depleted B16F1 melanoma cells. In sharp contrast, PC7 complemented Furin in cleaving Notch1 independently of PLC-mediated TGN access. Our study provides a proof in principle that compartment-specific biosensors can be used to gain insight into the regulation of PC trafficking and to map the tropism of PC-specific inhibitors. PMID- 29466744 TI - Single-Cell Droplet Microfluidic Screening for Antibodies Specifically Binding to Target Cells. AB - Monoclonal antibodies are a main player in modern drug discovery. Many antibody screening formats exist, each with specific advantages and limitations. Nonetheless, it remains challenging to screen antibodies for the binding of cell surface receptors (the most important class of all drug targets) or for the binding to target cells rather than purified proteins. Here, we present a high throughput droplet microfluidics approach employing dual-color normalized fluorescence readout to detect antibody binding. This enables us to obtain quantitative data on target cell recognition, using as little as 33 fg of IgG per assay. Starting with an excess of hybridoma cells releasing unspecific antibodies, individual clones secreting specific binders (of target cells co encapsulated into droplets) could be enriched 220-fold after sorting 80,000 clones in a single experiment. This opens the way for therapeutic antibody discovery, especially since the single-cell approach is in principle also applicable to primary human plasma cells. PMID- 29466743 TI - A Roadmap for Human Liver Differentiation from Pluripotent Stem Cells. AB - How are closely related lineages, including liver, pancreas, and intestines, diversified from a common endodermal origin? Here, we apply principles learned from developmental biology to rapidly reconstitute liver progenitors from human pluripotent stem cells (hPSCs). Mapping the formation of multiple endodermal lineages revealed how alternate endodermal fates (e.g., pancreas and intestines) are restricted during liver commitment. Human liver fate was encoded by combinations of inductive and repressive extracellular signals at different doses. However, these signaling combinations were temporally re-interpreted: cellular competence to respond to retinoid, WNT, TGF-beta, and other signals sharply changed within 24 hr. Consequently, temporally dynamic manipulation of extracellular signals was imperative to suppress the production of unwanted cell fates across six consecutive developmental junctures. This efficiently generated 94.1% +/- 7.35% TBX3+HNF4A+ human liver bud progenitors and 81.5% +/- 3.2% FAH+ hepatocyte-like cells by days 6 and 18 of hPSC differentiation, respectively; the latter improved short-term survival in the Fah-/-Rag2-/-Il2rg-/- mouse model of liver failure. PMID- 29466746 TI - T Cell LEGO: Identifying the Master Builders and What They Do. AB - Understanding how cell fate decisions are made during cellular differentiation and the mechanisms that drive them is a holy grail of cell biology. In this issue of Immunity, Hu et al.

PMID- 29466745 TI - Massively Parallel Single Nucleus Transcriptional Profiling Defines Spinal Cord Neurons and Their Activity during Behavior. AB - To understand the cellular basis of behavior, it is necessary to know the cell types that exist in the nervous system and their contributions to function. Spinal networks are essential for sensory processing and motor behavior and provide a powerful system for identifying the cellular correlates of behavior. Here, we used massively parallel single nucleus RNA sequencing (snRNA-seq) to create an atlas of the adult mouse lumbar spinal cord. We identified and molecularly characterized 43 neuronal populations. Next, we leveraged the snRNA seq approach to provide unbiased identification of neuronal populations that were active following a sensory and a motor behavior, using a transcriptional signature of neuronal activity. This approach can be used in the future to link single nucleus gene expression data with dynamic biological responses to behavior, injury, and disease.

PMID- 29466752 TI - Have Cytokines, Will Travel. AB - In many contexts, innate lymphoid cells (ILCs) are primarily tissue resident. By contrast, in a recent issue of Science, Huang et al.

PMID- 29466753 TI - Human T Cell Development, Localization, and Function throughout Life. AB - Throughout life, T cells coordinate multiple aspects of adaptive immunity, including responses to pathogens, allergens, and tumors. In mouse models, the role of T cells is studied in the context of a specific type of pathogen, antigen, or disease condition over a limited time frame, whereas in humans, T cells control multiple insults simultaneously throughout the body and maintain immune homeostasis over decades. In this review, we discuss how human T cells develop and provide essential immune protection at different life stages and highlight tissue localization and subset delineation as key determinants of the T cell functional role in immune responses. We also discuss how anatomic compartments undergo distinct age-associated changes in T cell subset composition and function over a lifetime. It is important to consider age and tissue influences on human T cells when developing targeted strategies to modulate T cell-mediated immunity in vaccines and immunotherapies. PMID- 29466754 TI - Understanding Subset Diversity in T Cell Memory. AB - Considerable advances have been made in recent years in understanding the generation and function of memory T cells. Memory T cells are typically parsed into discreet subsets based on phenotypic definitions that connote distinct roles in immunity. Here we consider new developments in the field and focus on how emerging differences between memory cells with respect to their trafficking, metabolism, epigenetic regulation, and longevity may fail to fit into small groups of "memory subsets." Rather, the properties of individual memory T cells fall on a continuum within each of these and other parameters. We discuss how this continuum influences the way that the efficacy of vaccination is assessed, as well as the suitability of a memory population for protective immunity. PMID- 29466755 TI - Transformation of Accessible Chromatin and 3D Nucleome Underlies Lineage Commitment of Early T Cells. AB - How chromatin reorganization coordinates differentiation and lineage commitment from hematopoietic stem and progenitor cells (HSPCs) to mature immune cells has not been well understood. Here, we carried out an integrative analysis of chromatin accessibility, topologically associating domains, AB compartments, and gene expression from HSPCs to CD4+CD8+ T cells. We found that abrupt genome-wide changes at all three levels of chromatin organization occur during the transition from double-negative stage 2 (DN2) to DN3, accompanying the T lineage commitment. The transcription factor BCL11B, a critical regulator of T cell commitment, is associated with increased chromatin interaction, and Bcl11b deletion compromised chromatin interaction at its target genes. We propose that these large-scale and concerted changes in chromatin organization present an energy barrier to prevent the cell from reversing its fate to earlier stages or redirecting to alternatives and thus lock the cell fate into the T lineages. PMID- 29466756 TI - Lineage-Determining Transcription Factor TCF-1 Initiates the Epigenetic Identity of T Cells. AB - T cell development is orchestrated by transcription factors that regulate the expression of genes initially buried within inaccessible chromatin, but the transcription factors that establish the regulatory landscape of the T cell lineage remain unknown. Profiling chromatin accessibility at eight stages of T cell development revealed the selective enrichment of TCF-1 at genomic regions that became accessible at the earliest stages of development. TCF-1 was further required for the accessibility of these regulatory elements and at the single cell level, it dictated a coordinate opening of chromatin in T cells. TCF-1 expression in fibroblasts generated de novo chromatin accessibility even at chromatin regions with repressive marks, inducing the expression of T cell restricted genes. These results indicate that a mechanism by which TCF-1 controls T cell fate is through its widespread ability to target silent chromatin and establish the epigenetic identity of T cells. PMID- 29466757 TI - Quiescent Tissue Stem Cells Evade Immune Surveillance. AB - Stem cells are critical for the maintenance of many tissues, but whether their integrity is maintained in the face of immunity is unclear. Here we found that cycling epithelial stem cells, including Lgr5+ intestinal stem cells, as well as ovary and mammary stem cells, were eliminated by activated T cells, but quiescent stem cells in the hair follicle and muscle were resistant to T cell killing. Immune evasion was an intrinsic property of the quiescent stem cells resulting from systemic downregulation of the antigen presentation machinery, including MHC class I and TAP proteins, and is mediated by the transactivator NLRC5. This process was reversed upon stem cell entry into the cell cycle. These studies identify a link between stem cell quiescence, antigen presentation, and immune evasion. As cancer-initiating cells can derive from stem cells, these findings may help explain how the earliest cancer cells evade immune surveillance.

AB - Immunosurveillance of secondary lymphoid organs (SLO) is performed by central memory T cells that recirculate through blood. Resident memory T (Trm) cells remain parked in nonlymphoid tissues and often stably express CD69. We recently identified Trm cells within SLO, but the origin and phenotype of these cells remains unclear. Using parabiosis of "dirty" mice, we found that CD69 expression is insufficient to infer stable residence of SLO Trm cells. Restimulation of nonlymphoid memory CD8+ T cells within the skin or mucosa resulted in a substantial increase in bona fide Trm cells specifically within draining lymph nodes. SLO Trm cells derived from emigrants from nonlymphoid tissues and shared some transcriptional and phenotypic signatures associated with nonlymphoid Trm cells. These data indicate that nonlymphoid cells can give rise to SLO Trm cells and suggest vaccination strategies by which memory CD8+ T cell immunosurveillance can be regionalized to specific lymph nodes.

PMID- 29466759 TI - Developmental Analysis of Bone Marrow Neutrophils Reveals Populations Specialized in Expansion, Trafficking, and Effector Functions. AB - Neutrophils are specialized innate cells that require constant replenishment from proliferative bone marrow (BM) precursors as a result of their short half-life. Although it is established that neutrophils are derived from the granulocyte macrophage progenitor (GMP), the differentiation pathways from GMP to functional mature neutrophils are poorly defined. Using mass cytometry (CyTOF) and cell cycle-based analysis, we identified three neutrophil subsets within the BM: a committed proliferative neutrophil precursor (preNeu) which differentiates into non-proliferating immature neutrophils and mature neutrophils. Transcriptomic profiling and functional analysis revealed that preNeu require the C/EBPepsilon transcription factor for their generation from the GMP, and their proliferative program is substituted by a gain of migratory and effector function as they mature. preNeus expand under microbial and tumoral stress, and immature neutrophils are recruited to the periphery of tumor-bearing mice. In summary, our study identifies specialized BM granulocytic populations that ensure supply under homeostasis and stress responses.

AB - We developed new gossypol (Gos)-based glycoconjugates through dehydration condensation of native Gos and chemically modified glycosides having aminooxy groups. The resultant glycoconjugates (glycoGos) were resistant to hydrolysis, although they were light-sensitive and slowly decomposed even under indoor lighting. The glycoGos also exhibited improved water solubility compared with native Gos, but their saturated concentrations in water were still low (6.4-17 MUM), due to their hydrophobic naphthyl rings. We also carried out WST-8 assays to assess the anticancer activity of the glycoGos on DLD-1 and HepG2 cells and found that the glycoGos having beta-lactosides and having beta-galactosides (specific ligands for asialoglycoprotein receptors) showed enhanced anticancer activity on HepG2 cells. PMID- 29466763 TI - Discovery and characterization of conserved and novel microRNAs from blunt snout bream (Megalobrama amblycephala) by deep sequencing. AB - MicroRNAs (miRNAs) are short, single stranded RNA molecules with approximately 22 nts in length, which regulate the stability and translation of messenger RNAs in several organisms. To increase the repertoire of miRNAs characterized in M. amblycephala, we used the deep sequencing technology to sequence a small RNA library using pooled RNA sample isolated from the 4 different tissues of M. amblycephala. A total of 309 conserved miRNAs that originated from 131 miRNA families were detected. 15 novel candidates miRNA were identified. Randomly selected 6 miRNAs were analyzed by stem-loop qRT-PCR and differential expression patterns were observed in 6 different tissues of M. amblycephala. Furthermore, the potential targets were predicted. GO analysis showed that most of the targets were involved in a broad range of physiological functions including fish growth, development, metabolism, stress responses and so on. Overall, our results significantly increased the number of novel miRNAs in M. amblycephala, which should be useful for further investigation into the role of miRNAs in regulating diverse biological processes. PMID- 29466764 TI - Molecular characterization of a CONSTANS gene from Sapium sebiferum (L.) Rxob. AB - Sapium sebiferum (L.) Roxb [S. sebiferum L.] is not only one of the most important economic woody oil trees, but is also a significant traditional herbal medicine in China. The CONSTANS (CO) gene is a key regulator of the long day dependent flowering pathway in Arabidopsis and other plants. To gain insight into the role of CO in woody oil trees, SsCO from S. sebiferum L. was isolated and characterized in this study. The corresponding SsCO protein, with 340 amino acid residues, included two putative zinc finger motifs B-Box1 and B-Box2 in the N terminal region and a conserved CCT domain in the C-terminal region. SsCO expression was high in flowers and exhibited distinct circadian regulation. In addition, SsCO had a transcriptional activation effect in yeast strains. Moreover, heterologous expression of SsCO complemented the late-flowering phenotype of the Arabidopsis CO mutant co-1. These results indicate that SsCO is a transcription factor and may regulate the photoperiodic flowering time and SsCO is regulated by circadian rhythms in Sapium sebiferum L. PMID- 29466765 TI - Genetic or pharmacological superoxide-hydrogen peroxide imbalances modulate the in vitro effects of lithium on glycogen synthase kinase-3beta. AB - INTRODUCTION: Lithium (Li), a mood stabilizer used to treat bipolar disorder (BP) symptoms has important anti-inflammatory effects by downregulation of glycogen synthase kinase-3 beta (GSK-3beta). However, sometime Li effect is not efficient in some patients suggesting genetic interference. Previous investigations described association between a genetic superoxide-hydrogen (S-HP) imbalance caused by a superoxide dismutase manganese dependent gene polymorphism (Val16Ala SOD2 SNP, rs4880) and differential anti-inflammatory response of some drugs and bioactive molecules. Therefore, we postulated here that S-HP imbalance could present some effect on GSK-3beta modulation by Li. METHODS: to test this hypothesis, a genetic and a pharmacological S-HP imbalance protocols were performed. In the two protocols, immune cells were activated by phythohemaglutin (PHA). The first one, used peripheral blood mononuclear cells (PBMCs) cultures carrying different Val16Ala-SOD2 genotypes, and the second used a commercial macrophage cell line RAW 264.7. Macrophages were exposed to paraquat to induce high S levels (VV-like cells) or porphyrin, that is a SOD2-like molecule that increase dismutation of S into HP (AA-like cells). In both protocols the Li effects on GSK-3beta gene and protein modulation as evaluated in 24 h cultures. The inflammatory activation was also analyzed by cellular proliferation in 72 h cell cultures. RESULTS: as expected PHA exposure triggered a strong upregulation of GSK-3beta gene expression (p <= 0.001), and Li exposure showed GSK-3beta gene downregulation from 0.7 mEq/L concentrations. However, Li modulatory effects on GSk-3beta gene and protein expression was directly influenced by basal S-HP balance. Presence of high S-basal levels (VV genotype and VV-like cells) induced attenuated Li anti-inflammatory effects in comparison with balanced and AA and AA like cells (p < 0.001). Despite methodological limitations related to in vitro assays, the whole of results suggested that Li anti-inflammatory effects is influenced by S-HP basal state and is plausible that its influence could contributes to resistance of some patients to Li treatment or to increase of intensity of some side effects Li-associated.

AB - This review is based on the presentations and deliberations at the 7th John Goldman Chronic Myeloid Leukemia (CML) and Myeloproliferative Neoplasms (MPN) Colloquium which took place in Estoril, Portugal on the 15th October 2017, and the 11th post-ASH International Workshop on CML and MPN which took place on the 6th-7th December 2016, immediately after the 58th American Society of Hematology Annual Meeting. Rather than present a resume of the proceedings, we have elected to address some of the topical translational research and clinically relevant topics in greater detail. We address recent updates in the genetics and epigenetics of MPN, the mechanisms of transformation by mutant calreticulin, advances in the biology and therapy of systemic mastocytosis, clinical updates on JAK2 inhibitors and other therapeutic approaches for patients with MPNs, cardiovascular toxicity related to tyrosine kinase inhibitors and the concept of treatment-free remission for patients with CML. PMID- 29466767 TI - 18F-labeled estradiol derivative for targeting estrogen receptor-expressing breast cancer. AB - INTRODUCTION: A novel radiotracer 1-(2-(2-(2-[18F]fluoroethoxy)ethoxy)ethyl)-1H 1,2,3-triazole-estradiol ([18F]FETE) was successfully synthesized, characterized and evaluated in mice for estrogen receptor (ER)-positive breast cancer targeting with positron emission tomography (PET) imaging. METHODS: The tosylate precursor 3 was radiolabeled with 18F and then reacted with 17alpha-ethinyl-estradiol to produce the final [18F]FETE. The physicochemical properties of [18F]FETE were tested in vitro, including determination of the octanol/water partition coefficient, stability and cellular uptake in MCF-7 (ER-positive) and MDA-MB-231 (ER-negative) cells. An ex vivo biodistribution study was performed in normal Sprague Dawley rats, and in vivo microPET imaging was performed on MCF-7 and MDA MB-231 tumor-bearing mice. The results of biodistribution and PET imaging of [18F]FETE were compared with that of known 16alpha-[18F]fuoro-17beta-estradiol ([18F]FES). Radiation dose estimates for [18F]FETE were also analyzed. RESULTS: [18F]FETE was obtained in high radiochemical yield (46.59 +/- 8.06%) with high radiochemical purity (>99%) after HPLC purification and high molar activity (15.45 +/- 3.15 GBq/MUmol). [18F]FETE is a moderate lipophilic compound with good in vitro stability and the total synthesis time was 55 to 65 min. In biodistribution studies, [18F]FETE showed high uptake in the ER-abundant uterine tissue of normal immature SD rats (8.55 +/- 1.21 and 6.83 +/- 1.70%ID/g at 1 h after intravenous and intraperitoneal injection, respectively), and could be blocked with estradiol effectively (the uterus uptake was decreased to 0.63 +/- 0.35%ID/g at 1 h after iv injection). MicroPET imaging of tumor-bearing mice with [18F]FETE at 1 h after iv injection revealed considerable uptake in ER-positive MCF-7 tumors (4.63 +/- 0.73%ID/g) that could be inhibited (1.47 +/- 0.29%ID/g) and low uptake in ER-negative MDA-MB-231 tumors (1.97 +/- 0.36%ID/g). [18F]FES has relatively low uptake in ER-positive tumor (0.24 +/- 0.19%ID/g) when compared with [18F]FETE. The adult female effective radiation dose of [18F]FETE in mice was estimated as 0.0022 mSv/MBq. CONCLUSIONS: A novel 17alpha-ethinyl-estradiol based ER probe [18F]FETE was developed with high molar activity and good in vitro stability. Based on the results of bio-evaluation in normal immature rats and tumor-bearing mice, it might be a promising candidate for specific PET imaging of ER-positive breast cancer. PMID- 29466769 TI - Insight into the local source of polybrominated diphenyl ethers in the developing Tibetan Plateau: The composition and transport around the Lhasa landfill. AB - In the background region of the Tibetan Plateau (TP), the rapid urbanization probably results in the massive generation of persistent organic pollutants (POPs), which lacks monitoring and evaluation. Since landfill could serve as an important sink of the locally used POPs, the analysis of POPs in the Tibetan landfill area might help us to understand the source composition and their transport in the TP. In this study, the concentration variations of polybrominated diphenyl ethers (PBDEs) in five soil profiles and seven surficial sediments around the largest Tibetan landfill were investigated. The total concentrations of PBDEs ranged from 128 to 1219 ng/kg in soils, and from 447 to 7295 ng/kg in sediments. The dominance of nona- and deca-BDEs possibly indicated the wide usage of deca-BDE as flame retardant in the TP. The vertical and spatial distribution patterns of PBDEs within soils plausibly revealed their main transport pathways by atmospheric dispersion and leachate seepage from landfill. Based on principal components analysis and multiple linear regression, these two pathways were estimated to account for 61% and 39% of the total concentrations, respectively. Additionally, the spatial and vertical distributions of octa-to deca-BDEs within soils were significantly influenced by soil particle size. Although the PBDEs inventory in the study area was comparatively low, the rapid urbanization in the TP might dramatically accelerate the PBDE emissions in the future. This study firstly introduced the presence of local PBDEs in the TP, and the inventory already influenced the surrounding environment. Once involved in the regional cycle of the TP, the local source of PBDEs from waste might significantly serve to raise background level resulting otherwise primarily from long-range atmospheric transport. PMID- 29466768 TI - Dynamics of the Intratumoral Immune Response during Progression of High-Grade Serous Ovarian Cancer. AB - PURPOSE: Tumor-infiltrating lymphocytes (TILs) have an established impact on the prognosis of high-grade serous ovarian carcinoma (HGSOC), however, their role in recurrent ovarian cancer is largely unknown. We therefore systematically investigated TIL densities and MHC class I and II (MHC1, 2) expression in the progression of HGSOC. EXPERIMENTAL DESIGN: CD3+, CD4+, CD8+ TILs and MHC1, 2 expression were evaluated by immunohistochemistry on tissue microarrays in 113 paired primary and recurrent HGSOC. TILs were quantified by image analysis. All patients had been included to the EU-funded OCTIPS FP7 project. RESULTS: CD3+, CD4+, CD8+ TILs and MHC1 and MHC2 expression showed significant correlations between primary and recurrent tumor levels (Spearman rho 0.427, 0.533, 0.361, 0.456, 0.526 respectively; P<.0001 each). Paired testing revealed higher CD4+ densities and MHC1 expression in recurrent tumors (Wilcoxon P=.034 and P=.018). There was also a shift towards higher CD3+ TILs levels in recurrent carcinomas when analyzing platinum-sensitive tumors only (Wilcoxon P=.026) and in pairs with recurrent tumor tissue from first relapse only (Wilcoxon P=.031). High MHC2 expression was the only parameter to be significantly linked to prolonged progression-free survival after first relapse (PFS2, log-rank P=.012). CONCLUSIONS: This is the first study that analyzed the development of TILs density and MHC expression in paired primary and recurrent HGSOC. The level of the antitumoral immune response in recurrent tumors was clearly dependent on the one in the primary tumor. Our data contribute to the understanding of temporal heterogeneity of HGSOC immune microenvironment and have implications for selection of samples for biomarker testing in the setting of immune-targeting therapeutics. PMID- 29466770 TI - Neonatal triphenyl phosphate and its metabolite diphenyl phosphate exposure induce sex- and dose-dependent metabolic disruptions in adult mice. AB - The widespread application of organophosphorous flame retardants (OPFRs) has led to considerable human exposure, with major concerns regarding their health risks. Herein, we investigate the effects of triphenyl phosphate (TPP), one of the most widely used OPFRs, and one of its main metabolite diphenyl phosphate (DPP) on the endocrine systems and metabolic profiles after neonatal exposure from postnatal days 1-10 at two dosages (2 and 200 MUg per day). Both TPP and DPP had no negative effect on uterine weight, glucose tolerance, and estradiol. 1H-NMR-based metabolomics revealed a sex-specific metabolic disturbance of TPP. Specifically, low dose of TPP altered the metabolic profiles of male mice while exerting no significant effects on female ones. Furthermore, a dose-dependent effect of TPP in male mice was observed, where a low toxicity dose up-regulated lipid-related metabolites, while a high toxicity dose down-regulated the pyruvate metabolism and TCA cycles. These results highlight the importance of carefully assessing the health impact of TPP on infants. PMID- 29466771 TI - Effects of prenatal exposure to air pollution on preeclampsia in Shenzhen, China. AB - The impact of ambient air pollution on pregnant women is a concern in China. However, little is known about the association between air pollution and preeclampsia and the potential modifying effects of meteorological conditions have not been assessed. This study aimed to assess the effects of prenatal exposure to air pollution on preeclampsia, and to explore whether temperature and humidity modify the effects. We performed a retrospective cohort study based on 1.21 million singleton births from the birth registration system in Shenzhen, China, between 2005 and 2012. Daily average measurements of particulate matter <10 MUm (PM10), sulfur dioxide (SO2), nitrogen dioxide (NO2), air temperature (T), and dew point (Td) were collected. Logistic regression models were performed to estimate associations between air pollution and preeclampsia during the first and second trimesters, and during the entire pregnancy. In each time window, we observed a positive gradient of increasing preeclampsia risk with increasing quartiles of PM10 and SO2 exposure. When stratified by T and Td in three categories (<5th, 5th -95th, and >95th percentile), we found a significant interaction between PM10 and Td on preeclampsia; the adverse effects of PM10 increased with Td. During the entire pregnancy, there was a null association between PM10 and preeclampsia under Td < 5th percentile. Preeclampsia risk increased by 23% (95% CI: 19-26%) when 5th < Td < 95th percentile, and by 34% (16 55%) when Td > 95th percentile. We also found that air pollution effects on preeclampsia in autumn/winter seasons were stronger than those in the spring/summer. This is the first study to address modifying effects of meteorological factors on the association between air pollution and preeclampsia. Findings indicate that prenatal exposure to PM10 and SO2 increase preeclampsia risk in Shenzhen, China, and the effects could be modified by humidity. Pregnant women should limit air pollution exposure, particularly during humid periods. PMID- 29466772 TI - Effects of Fe-S-As coupled redox processes on arsenic mobilization in shallow aquifers of Datong Basin, northern China. AB - High arsenic groundwater generally coexists with elevated Fe2+ concentrations (mg L-1 levels) under reducing conditions, but an explanation for the extremely high arsenic (up to ~2690) concentrations at very low Fe2+ (i.e., MUg L-1 levels) in groundwater of Datong Basin remains elusive. Field groundwater investigation and laboratory microcosm experiments were implemented in this study. The field groundwater was characterized by weakly alkaline (pH 7.69 to 8.34) and reducing conditions (Eh -221.7 to -31.9 mV) and arsenic concentration averages at 697 MUg L-1. Acinetobacter (5.9-51.3%), Desulfosporosinus (4.6-30.2%), Brevundimonas (3.9 19%) and Pseudomonas (3.2-14.6%) were identified as the dominant genera in the bacterial communities. Bacterially mediated arsenate reduction, Fe(III) reduction, and sulfate reduction are processes occurring (or having previously occurred) in the groundwater. Results from incubation experiment (27 d) revealed that nitrate, arsenate, and Fe(III)/sulfate reduced sequentially with time under anoxic conditions, while Fe(III) and sulfate reduction processes had no obvious differences, occurring almost simultaneously. Moreover, low Fe2+ concentrations were attributed to initially high pH conditions, which relatively retarded Fe(III) reduction. In addition, arsenic behavior in relation to groundwater redox conditions, matrices, and solution chemistry were elaborated. Bacterial arsenate reduction process proceeded before Fe(III) and sulfate reduction in the incubation experiment, and the total arsenic concentration (dominated by arsenite) gradually increased from ~7 to 115 MUg L-1 as arsenate was reduced. Accordingly, bacterially mediated reductive desorption of arsenate is identified as the main process controlling arsenic mobility, while Fe(III) reduction coupled with sulfate reduction are secondary processes that have also contributed to arsenic enrichment in the study site. Overall, this study provide important insights into the mechanism controlling arsenic mobility under weakly alkaline and reducing conditions, and furnishes that arsenate reduction by bacteria play a major role leading to high accumulation of desorbed arsenite in groundwater. PMID- 29466773 TI - Discovery of 2,4,6-trisubstitued pyrido[3,4-d]pyrimidine derivatives as new EGFR TKIs. AB - Targeting acquired drug resistance is the major challenge in the treatment of EGFR-driven non-small cell lung cancer (NSCLC). In this study, a novel class of compounds containing pyrido[3,4-d]pyrimidine scaffold was designed as new generation EGFR-TKIs to overcome this challenge. The most promising compound B30 inhibited HCC827 and H1975 cells growth with the IC50 values of 0.044 MUM and 0.40 MUM, respectively. Meanwhile, B30 displayed potent inhibitory activity against the EGFRL858R (IC50 = 1.1 nM) and EGFRL858R/T790M/C797S (IC50 = 7.2 nM). B30 could suppress EGFR phosphorylation in a dose-dependent manner in HCC827 cell line and significantly induce the apoptosis of HCC827 cells. Molecular docking indicated that the hydroxyl in B30 could form additional hydrogen bond with mutant Ser797. These findings strongly support our assumption that 2,4,6 trisubstitued pyrido[3,4-d] pyrimidine derivatives can serve as EGFR-TKIs. The predicted hydrogen bond interaction formed by a small molecule inhibitor with mutant Ser797 is available to design the fourth-generation EGFR-TKIs.

AB - A series of novel tacrine-phenolic acid dihybrids and tacrine-phenolic acid ligustrazine trihybrids were synthesized, characterized and screened as novel potential anti-Alzheimer drug candidates. These compounds showed potent inhibition activity towards cholinesterases (ChEs), among of them, 9i was the most potent one towards acetylcholinesterase (eeAChE, IC50 = 3.9 nM; hAChE, IC50 = 65.2 nM). 9i could also effectively block beta-amyloid (Abeta) self-aggregation with an inhibition ratio of 47% at 20 MUM. In addition, its strong anti-oxidation activity could protect PC12 cells from CoCl2-damage in the experimental condition while no neurotoxicity. Furthermore, its hepatotoxicity was lower than tacrine in vitro and in vivo. Kinetic and molecular modeling studies revealed that 9i worked in a mixed-type way, could interact simultaneously with catalytic active site (CAS) and peripheral anionic site (PAS) of AChE. Therefore, 9i was a promising multifunctional candidate for the treatment of AD. PMID- 29466775 TI - Novel Tacrine-Hydroxyphenylbenzimidazole hybrids as potential multitarget drug candidates for Alzheimer's disease. AB - Alzheimer's disease (AD) is a severe age-dependent neurodegenerative disorder affecting millions of people, with no cure so far. The current treatments only achieve some temporary amelioration of the cognition symptoms. The main characteristics of the patient brains include the accumulation of amyloid plaques and neurofibrillary tangles (outside and inside the neurons) but also cholinergic deficit, increased oxidative stress and dyshomeostasis of transition metal ions. Considering the multi-factorial nature of AD, we report herein the development of a novel series of potential multi-target directed drugs which, besides the capacity to recover the cholinergic neurons, can also target other AD hallmarks. The novel series of tacrine-hydroxyphenylbenzimidazole (TAC-BIM) hybrid molecules has been designed, synthesized and studied for their multiple biological activities. These agents showed improved AChE inhibitory activity (IC50 in nanomolar range), as compared with the single drug tacrine (TAC), and also a high inhibition of self-induced- and Cu-induced-Abeta aggregation (up to 75%). They also present moderate radical scavenging activity and metal chelating ability. In addition, neuroprotective studies revealed that all these tested compounds are able to inhibit the neurotoxicity induced by Abeta and Fe/AscH(-) in neuronal cells. Hence, for this set of hybrids, structure-activity relationships are discussed and finally it is highlighted their real promising interest as potential anti-AD drugs. PMID- 29466776 TI - Structure-based discovery of cytotoxic dimeric tetrahydroxanthones as potential topoisomerase I inhibitors from a marine-derived fungus. AB - DNA topoisomerase I (Topo I) is an important anticancer drug target, and xanthone dimers are considered to be a new kind of Topo I inhibitor chemotypes. Based on the characteristics of dimeric xanthone structures, five new dimeric xanthones (1 5) and two known SAD isomers (6 and 7) were isolated from the mangrove-derived fungus Aspergillus vericolor. The absolute configurations of compounds 1-7, entailing both central and axial chirality elements, were established by a combination of ECD comparison, chemical conversions, and biogenetic considerations. Compounds 1-7 possessed high structural diversity and exhibited cytotoxicity at different levels. The selected new compounds 1, 2, and 5 showed Topo I inhibition properties and the most potent compound 1, an atropisomer of compound 2, was confirmed to inhibit Topo I-mediated DNA relaxation by targeting Topo I, thereby, arresting the cell cycle process and inducing necrosis in cancer cells. Molecular docking studies showed that compound 1 could bind DNA by pi-pi interaction and DNA Topo I by hydrogen bonds to form a ternary complex.

AB - To improve the druggability of salinomycin, a 20-epi-amino-20-deoxysalinomycin derivatives library was synthesized with high efficacy from which a few salinomycin derivatives with high potency and selectivity were identified through comprehensive cytotoxicity assay, including a fluorine-19 magnetic resonance sensitive tool molecule. Using a K-ras cellular model, salinomycin and its derivatives showed different molecular mode of action from literature reports. These results would be valuable for developing salinomycin-based cancer therapy. PMID- 29466778 TI - New MD2 inhibitors derived from curcumin with improved anti-inflammatory activity. AB - An overactive Toll-like receptor (TLR) signaling complex is a significant pathogenic factor of acute and chronic inflammatory diseases. The natural product curcumin is reported to inhibit the TLR4 co-receptor, MD2 (myeloid differentiation protein 2), but its low in vivo bioavailability limits its therapeutic potential. We developed new curcumin analogs (MACs) with removal of the beta-diketone moiety and substituted residues in benzene rings, and identify these as potential MD2 inhibitors with improved inhibition potency and stability over that of curcumin. Specifically, MAC 17 and 28 showed the highest anti inflammatory activity, with >90% inhibition of LPS-stimulated cytokine secretion from macrophages, and protected against LPS-induced acute lung injury and sepsis. The MACs inhibited the TLR4-MD2 signaling complex through competition with LPS for binding on MD2, likely at Arg90. Our findings indicated that MAC 17 and 28 are promising candidates for future development as therapeutic drugs for inflammatory diseases with an endotoxin etiology. PMID- 29466779 TI - Simultaneous decomplexation in blended Cu(II)/Ni(II)-EDTA systems by electro Fenton process using iron sacrificing electrodes. AB - This research explored the application of electro-Fenton (E-Fenton) technique for the simultaneous decomplexation in blended Cu(II)/Ni(II)-EDTA systems by using iron sacrificing electrodes. Standard discharge (0.3 mg L-1 for Cu and 0.1 mg L-1 for Ni in China) could be achieved after 30 min reaction under the optimum conditions (i.e. initial solution pH of 2.0, H2O2 dosage of 6 mL L-1 h-1, current density of 20 mA/cm2, inter-electrode distance of 2 cm, and sulfate electrolyte concentration of 2000 mg L-1). The distinct differences in apparent kinetic rate constants (kapp) and intermediate removal efficiencies corresponding to mere and blended systems indicated the mutual promotion effect toward the decomplexation between Cu(II) and Ni(II). Massive accumulation of Fe(III) favored the further removal of Cu(II) and Ni(II) by metal ion substitution. Species distribution results demonstrated that the decomplexation of metal-EDTA in E-Fenton process was mainly contributed to the combination of various reactions, including Fenton reaction together with the anodic oxidation, electro-coagulation (E-coagulation) and electrodeposition. Unlike hypophosphite and citrate, the presence of chlorine ion displayed favorable effects on the removal efficiencies of Cu(II) and Ni(II) at low dosage, but facilitated the ammonia nitrogen (NH4+-N) removal only at high dosage. PMID- 29466780 TI - A novel polymer probe for Zn(II) detection with ratiometric fluorescence signal. AB - A conjugated polymer probe comprised of fluorene, quinolone and benzothiazole units was designed and synthesized by the Suzuki coupling reaction. Through the studies of photophysical and thermal properties, the polymer displays blue emitting feature and good thermal stability. A ratiometric fluorescence signal of the probe for Zn(II) was observed in ethanol with a new emission peak at 555 nm. The probe possesses a high selectivity and sensitivity for Zn(II) during familiar metal ions in ethanol. The detection limit of the probe for Zn (II) is up to 10-8 mol/L. The electron distributions of the polymer before and after bonding with Zn (II) were investigated by the Gaussian 09 software, which agreed with the experimental results. Noticeably, based on the color property of the probe with Zn(II), a series of color test paper were developed for visual detecting Zn(II) ions. This work helps to provide a platform or pattern for the development of polymer fluorescence probe in the chemosensor field. PMID- 29466781 TI - An active learning representative subset selection method using net analyte signal. AB - To guarantee accurate predictions, representative samples are needed when building a calibration model for spectroscopic measurements. However, in general, it is not known whether a sample is representative prior to measuring its concentration, which is both time-consuming and expensive. In this paper, a method to determine whether a sample should be selected into a calibration set is presented. The selection is based on the difference of Euclidean norm of net analyte signal (NAS) vector between the candidate and existing samples. First, the concentrations and spectra of a group of samples are used to compute the projection matrix, NAS vector, and scalar values. Next, the NAS vectors of candidate samples are computed by multiplying projection matrix with spectra of samples. Scalar value of NAS is obtained by norm computation. The distance between the candidate set and the selected set is computed, and samples with the largest distance are added to selected set sequentially. Last, the concentration of the analyte is measured such that the sample can be used as a calibration sample. Using a validation test, it is shown that the presented method is more efficient than random selection. As a result, the amount of time and money spent on reference measurements is greatly reduced. PMID- 29466782 TI - Estimation of light source colours for light pollution assessment. AB - The concept of the smart city raised several technological and scientific issues including light pollution. There are various negative impacts of light pollution on economy, ecology, and heath. This paper deals with the census of the colour of light emitted by lamps used in a city environment. To this end, we derive a light bulb colour estimator based on Bayesian reasoning, directional data, and image formation model in which the usual concept of reflectance is not used. All choices we made are devoted to designing an algorithm which can be run almost in real-time. Experimental results show the effectiveness of the proposed approach.

A dilemma exists, however, as to whether angiogenic stimulation by FGF2 for the prevention and treatment of atherogenesis is feasible. The aim of this study is to investigate the effect of the 18-kDa FGF-2 isoform on atherosclerosis progression in high-fat diet-fed apolipoprotein E knockout (ApoE-/-) mice. METHODS: We established a model of atherosclerosis using ApoE and 18-kDa FGF-2 gene double knockout mice. They were randomly divided into three groups depending on the duration of diet: 8 weeks, 12 weeks and 16 weeks. Then, we studied the morphology and inflammatory factor staining in the atherosclerosis plaque of these mice. RESULTS: Knockout of the 18-kDa FGF-2 isoform did not change the metabolic characteristics of the mice. Compared to the control group, knockout of the 18 kDa FGF-2 isoform significantly attenuated atherogenesis, reduced aortic plaques, reduced macrophage infiltration and suppressed oxidative stress in mice fed with a high fat diet at all-time points. CONCLUSIONS: 18-kDa FGF-2 aggravated the inflammatory reaction of atherosclerosis. PMID- 29466784 TI - Clinical, Hormonal, and Genetic Evaluation of Idiopathic Nonobstructive Azoospermia and Klinefelter Syndrome Patients. AB - To investigate the clinical, hormonal, and genetic factors in infertile men with idiopathic nonobstructive azoospermia (NOA) or azoospermic Klinefelter syndrome (KFS), a total of 556 and 96 patients, respectively, were included in this study. All patient samples were analyzed cytogenetically. Serum reproductive hormone levels were measured. Microdeletions in the azoospermia factor (AZF) region of the Y chromosome were detected by multiplex PCR using 16 specific sequence-tagged sites. FSH and LH levels in both NOA and KFS patients were significantly higher than the normal range, and the testosterone level in KFS patients was significantly lower. Ninety-two (95.8%) of the KFS patients showed non-mosaic 47,XXY karyotypes and 47,XXY,inv(9)(p11.1q13); the other KFS patients had mosaic karyotypes of 47,XXY/46,XY, 47,XXY/46,XX, and 47,XXY/48,XXXY/46,XX. Among the 556 idiopathic NOA patients with normal karyotypes, 67 (12.05%) had microdeletions in the AZF region of the Y chromosome. Microdeletions were most frequently detected in the AZFc region, followed by AZFa, AZFb, AZFbc, and partial AZFc deletions. However, Y chromosome microdeletions were not found in any of the azoospermic KFS patients. In view of the hormonal and genetic abnormalities in infertile men with idiopathic NOA and with azoospermic KFS, genetic testing for karyotype, Y chromosome microdeletions, and hormonal parameters is advocated. PMID- 29466785 TI - Down-Regulation of H3K4me3 by MM-102 Facilitates Epigenetic Reprogramming of Porcine Somatic Cell Nuclear Transfer Embryos. AB - BACKGROUND/AIMS: Aberrantly high levels of H3K4me3, caused by incomplete epigenetic reprogramming, likely cause a low efficiency of somatic cell nuclear transfer (SCNT). Smal molecule inhibitors aimed at epigenetic modification can be used to improve porcine SCNT embryo development. In this study, we examined the effects of MM-102, an H3K4 histone methyltransferase inhibitor, on porcine SCNT preimplantation embryos to investigate the mechanism by which H3K4 methylation regulated global epigenetic reprograming during SCNT. METHODS: MM-102 was added to the SCNT embryos culture system and the global levels of various epigenetic modifications were measured by immunofluorescence (IF) staining and were quantified by Image J software. Relative genes expression levels were detected by quantitative real-time PCR. RESULTS: MM-102 (75 MUM) treatment reduced global H3K4, H3K9 methylation and 5mC levels especially at the zygotic gene activation (ZGA) and blastocyst stages. MM-102 treatment mainly down-regulated a series of DNA and histone methyltransferases, and up-regulated a number of hitone acetyltransferases and transcriptional activators. Furthermore, MM-102 treatment positively regulated the mRNA expression of genes related to pluripotency (OCT4, NANOG, CDX2) and apoptosis (BCL2). CONCLUSION: Down-regulation of H3K4me3 with MM 102 rescued aberrant gene expression patterns of a series of epigenetic chromatin modification enzymes, pluripotent and apoptotic genes at the ZGA and blastocyst stages, thereby greatly improving porcine SCNT efficiency and blastocyst quality, making them more similar to in vivo embryos (IVV). PMID- 29466786 TI - Long-Term Vitamin D Supplementation and the Effects on Recurrence and Metabolic Status of Cervical Intraepithelial Neoplasia Grade 2 or 3: A Randomized, Double Blind, Placebo-Controlled Trial. AB - OBJECTIVE: This study was conducted to evaluate the effects of vitamin D supplementation on the recurrence and metabolic status of patients with cervical intraepithelial neoplasia grade 2 or 3 (CIN2/3). METHODS: This randomized, double blind, placebo-controlled trial was carried out among 58 women diagnosed with CIN2/3. Participants were randomly assigned into 2 groups to receive either 50,000 IU vitamin D3 (n = 29) or placebo (n = 29) every 2 weeks for 6 months. RESULTS: The recurrence rate of CIN1/2/3 was 18.5 and 48.1% in the vitamin D and placebo groups respectively (p = 0.02). When we excluded CIN1, the recurrence rate of CIN2/3 became nonsignificant. Vitamin D supplementation significantly decreased fasting plasma glucose (-7.8 +/- 9.2 vs. -1.1 +/- 8.6 mg/dL, p = 0.006) and insulin levels (-3.2 +/- 4.8 vs. -0.9 +/- 3.4 uIU/mL, p = 0.03), and significantly increased quantitative insulin sensitivity check index (0.01 +/- 0.02 vs. 0.002 +/- 0.01, p = 0.02) compared with the placebo. Additionally, there was a significant decrease in high-sensitivity C-reactive protein (-815.3 +/- 1,786.2 vs. 717.5 +/- 1,827.3 ng/mL, p = 0.002) and a significant increase in total antioxidant capacity (113.4 +/- 137.4 vs. -53.7 +/- 186.7 mmol/L, p < 0.001) following the supplementation of vitamin D compared with the placebo. CONCLUSIONS: Vitamin D3 supplementation for 6 months among women with CIN2/3 had beneficial effects on CIN1/2/3 recurrence and metabolic status; however, it did not affect CIN2/3 recurrence. PMID- 29466787 TI - A Strategy for Optimizing the Combination of Active Components Based on Chinese Medicinal Formula Sheng-Mai-San for Myocardial Ischemia. AB - BACKGROUND/AIMS: Traditional Chinese medicine (TCM) has been used in clinical practice for thousands of years and has accumulated considerable knowledge concerning the in vivo efficacy of targeting complicated diseases. TCM formulae are a mixture of hundreds of chemical components with multiple potential targets, essentially acting as a combination therapy of multi-component drugs. However, the obscure substances and the unclear molecular mechanisms are obstacles to their further development and internationalization. Therefore, it is necessary to develop new modern drugs based on the combination of effective components in TCM with exact clinical efficacy. In present study, we aimed to detect optimal ratio of the combination of effective components based on Sheng-Mai-San for myocardial ischemia. METHODS: On the basis of preliminary studies and references of relevant literature about Sheng-Mai-San for myocardial ischemia, we chose three representative components (ginsenoside Rb1 (G), ruscogenin (R) and schisandrin (S)) for the optimization design studies. First, the proper proportion of the combination was explored in different myocardial ischemia mice induced by isoproterenol and pituitrin based on orthogonal design. Then, the different proportion combinations were further optimized through uniform design in a multi model and multi-index mode. Finally, the protective effect of combination was verified in three models of myocardial ischemia injured by ischemia/reperfusion, chronic intermittent hypoxia and acute infarction. RESULTS: The optimized combination GRS (G: 6 mg/kg, R: 0.75 mg/kg, S: 6 mg/kg) obtained by experimental screening exhibited a significant protective effect on myocardial ischemia injury, as evidenced by decreased myocardium infarct size, ameliorated histological features, decreased myocardial myeloperoxidase (MPO) and malondiadehyde (MDA), calcium overload, and decreased serum lactate dehydrogenase (LDH), creatine kinase MB isoenzyme (CK-MB), cardiac troponin I (cTn-I) activity. In addition, the interactions of three components in combination GRS were also investigated. The combination, compared to G, R and S, could significantly reduce the concentration of serum CK-MB and cTn-I, and decrease myocardial infarct size, which demonstrated the advantages of this combination for myocardial ischemia. CONCLUSION: Our results demonstrated that the optimized combination GRS could exert significant cardioprotection against myocardial ischemia injury with similar effect compared to Sheng Mai preparations, which might provide some pharmacological evidences for further development of new modern Chinese drug for cardiovascular diseases basing on traditional Chinese formula with affirmative therapeutic effect. PMID- 29466788 TI - Metformin-Induced Changes of the Coding Transcriptome and Non-Coding RNAs in the Livers of Non-Alcoholic Fatty Liver Disease Mice. AB - BACKGROUND/AIMS: Recent studies have suggested that changes in non-coding mRNA play a key role in the progression of non-alcoholic fatty liver disease (NAFLD). Metformin is now recommended and effective for the treatment of NAFLD. We hope the current analyses of the non-coding mRNA transcriptome will provide a better presentation of the potential roles of mRNAs and long non-coding RNAs (lncRNAs) that underlie NAFLD and metformin intervention. METHODS: The present study mainly analysed changes in the coding transcriptome and non-coding RNAs after the application of a five-week metformin intervention. Liver samples from three groups of mice were harvested for transcriptome profiling, which covered mRNA, lncRNA, microRNA (miRNA) and circular RNA (circRNA), using a microarray technique. RESULTS: A systematic alleviation of high-fat diet (HFD)-induced transcriptome alterations by metformin was observed. The metformin treatment largely reversed the correlations with diabetes-related pathways. Our analysis also suggested interaction networks between differentially expressed lncRNAs and known hepatic disease genes and interactions between circRNA and their disease related miRNA partners. Eight HFD-responsive lncRNAs and three metformin responsive lncRNAs were noted due to their widespread associations with disease genes. Moreover, seven miRNAs that interacted with multiple differentially expressed circRNAs were highlighted because they were likely to be associated with metabolic or liver diseases. CONCLUSIONS: The present study identified novel changes in the coding transcriptome and non-coding RNAs in the livers of NAFLD mice after metformin treatment that might shed light on the underlying mechanism by which metformin impedes the progression of NAFLD. PMID- 29466789 TI - Two-Port Fetoscopic Repair of Myelomeningocele in Fetal Lambs. AB - OBJECTIVE: The aim of this study was to assess the feasibility and the effectiveness of a fetoscopic myelomeningocele (MMC) repair with a running single suture using a 2-port access in the sheep model. METHODS: Eighteen fetuses underwent surgical creation of a MMC defect at day 75. Fetuses were then randomized into 3 groups. Four fetuses remained untreated (control group). In the other 14 fetuses, a prenatal repair was performed at day 90: 7 fetuses had an open repair (oMMC), and 7 fetuses had a fetoscopic repair (fMMC) using a single layer running suture through a 2-port access. Lambs were sacrificed at term, and histological examinations were performed. RESULTS: Hindbrain herniation was observed in all live lambs in the control group. A complete closure of the defect was achieved in all the lambs of the fMMC group. A complete healing of the defect and no hindbrain herniation were observed in all live lambs of the oMMC and fMMC groups. The durations of surgeries were not statistically different between the oMMC and the fMMC groups (60 vs. 53 min, p = 0.40), as was the risk of fetal loss (fMMC: 1/7, oMMC: 3/7, p = 0.56). DISCUSSION: Fetoscopic repair of MMC can be performed using a single-layer running suture through a 2-port access and may be promising to reduce the risk of premature rupture of membranes. PMID- 29466790 TI - Elevated Faecal Calprotectin Levels are a Reliable Non-Invasive Screening Tool for Small Bowel Crohn's Disease in Patients Undergoing Capsule Endoscopy. AB - BACKGROUND: Approximately 10% of Crohn's disease (CD) patients have this disease affecting the small bowel (SB) beyond the reach of Ileo-colonoscopy. Capsule endoscopy (SBCE) is the recommended investigation for SB disease. An accurate and inexpensive biomarker would help identify at-risk patients. AIM: To examine the efficacy of faecal calprotectin (FC) and C-reactive protein (CRP) as predictors of SBCE findings in suspected and known CD. METHODS: A prospective observational study. Consecutive patients referred for SBCE gave FC and CRP samples. The diagnostic accuracy for SB CD based on SBCE result was calculated for both FC and CRP. RESULTS: Of 100 invitees, FC and SBCE results were available in 64 cases. Correlation between FC >50 ug/g and SBCE result was poor K = 0.163; sensitivity, specificity, positive predictive value (PPV) and negative predictive values for ileitis were 60, 61, 32 and 83% respectively. PPV and specificity improved at FC >100 ug/g, 76 and 40%, correlation remained fair, K = 0.259. Receiver operating characteristic analysis had a sensitivity of 47% and specificity of 90% for FC >194 ug/g. CRP alone or in combination was an inaccurate predictor of ileitis. CONCLUSION: Our study suggests that FC level >194 ug/g may be a useful SBCE filter test, identifying patients at risk of SB CD.

PMID- 29466791 TI - Lysophosphatidic Acid Induces Ligamentum Flavum Hypertrophy Through the LPAR1/Akt Pathway. AB - BACKGROUND/AIMS: Hypertrophic ligamentum flavum (LF) is a major cause of lumbar spinal stenosis. Our previous work showed that high levels of lysophosphatidic acid (LPA) expression are positively correlated with LF hypertrophy. This study aimed to further unveil how LPA regulates LF hypertrophy Methods: We studied LPAR1 expression in human LF cells using PCR and western blotting. Cell viability cell cycle, apoptosis rate and molecular mechanisms were assayed in LPAR1 knockdown or overexpression LF cells. LF hypertrophy and the molecular mechanism was confirmed in human samples and in in vivo studies. RESULTS: The expression of LPA and its receptor LPAR1 is significantly higher in tissues or cells harvested from hypertrophic LF compared to healthy controls. Moreover, LPA promoted LF cell proliferation by interacting with LPAR1. This conclusion is supported by the fact that depletion or overexpression of LPAR1 changed the effect of LPA on LF cell proliferation. LPA also inhibits apoptosis in LF cells through the receptor LPAR1. Importantly, we demonstrated that the LPA-LPAR1 interaction initiated Akt phosphorylation and determined cell proliferation and apoptosis. Our in vitro findings were supported by our in vivo evidence that lyophilized LPA significantly induced LF hypertrophy via the LPAR1-Akt signaling pathway. More importantly, targeted inhibition of LPAR1 by Ki16425 with a gel sponge implant effectively reduced LPA-associated LF hypertrophy. Taken together, these data indicate that LPA binds to the receptor LPAR1 to induce LF cell proliferation and inhibit apoptosis by activating AKT signaling cascades. Targeting this signaling cascade with Ki16425 is a potential therapeutic strategy for preventing LF hypertrophy. CONCLUSION: LPA-LPAR1-Akt activation is positively correlated with the proliferation and survival of LF cells. LPAR1 could be a target for new drugs and the development of new therapeutic methods for treating LF hypertrophy. PMID- 29466793 TI - A Novel Method to Detect Early Colorectal Cancer Based on Chromosome Copy Number Variation in Plasma. AB - BACKGROUND/AIMS: Colonoscopy screening has been accepted broadly to evaluate the risk and incidence of colorectal cancer (CRC) during health examination in outpatients. However, the intrusiveness, complexity and discomfort of colonoscopy may limit its application and the compliance of patients. Thus, more reliable and convenient diagnostic methods are necessary for CRC screening. Genome instability, especially copy-number variation (CNV), is a hallmark of cancer and has been proved to have potential in clinical application. METHODS: We determined the diagnostic potential of chromosomal CNV at the arm level by whole-genome sequencing of CRC plasma samples (n = 32) and healthy controls (n = 38). Arm level CNV was determined and the consistence of arm-level CNV between plasma and tissue was further analyzed. Two methods including regular z score and trained Support Vector Machine (SVM) classifier were applied for detection of colorectal cancer. RESULTS: In plasma samples of CRC patients, the most frequent deletions were detected on chromosomes 6, 8p, 14q and 1p, and the most frequent amplifications occurred on chromosome 19, 5, 2, 9p and 20p. These arm-level alterations detected in plasma were also observed in tumor tissues. We showed that the specificity of regular z score analysis for the detection of colorectal cancer was 86.8% (33/38), whereas its sensitivity was only 56.3% (18/32). Applying a trained SVM classifier (n = 40 in trained group) as the standard to detect colorectal cancer relevance ratio in the test samples (n = 30), a sensitivity of 91.7% (11/12) and a specificity 88.9% (16/18) were finally reached. Furthermore, all five early CRC patients in stages I and II were successfully detected. CONCLUSION: Trained SVM classifier based on arm-level CNVs can be used as a promising method to screen early-stage CRC. PMID- 29466794 TI - FOXO1, a Potential Therapeutic Target, Regulates Autophagic Flux, Oxidative Stress, Mitochondrial Dysfunction, and Apoptosis in Human Cholangiocarcinoma QBC939 Cells. AB - BACKGROUND/AIMS: Autophagy is an evolutionarily conserved catabolic mechanism to maintain energy homeostasis and to remove damaged cellular components, which plays an important role in the survival of various cells. Inhibiting autophagy is often applied as a new strategy to halt the growth of cancer cells. METHODS: The effect of FOXO1 gene on cellular function and apoptosis and its underlying mechanisms were investigated in cultured QBC939 cells by the methylthiazoletetrazolium (MTT) assay, western blot, DCFDA mitochondrial membrane potential, and ATP content measurement. FOXO1 siRNA was applied to down-regulate FOXO1 expression in QBC939 cells. RESULTS: Here we reported that FOXO1, acetylation of FOXO1 (Ac-FOXO1) and the following interaction between Ac-FOXO1 and Atg7 regulated the basal and serum starvation (SS)-induced autophagy as evidenced by light chain 3 (LC3) accumulation and p62 degration. Either treatment with FOXO1 siRNA or resveratrol, a sirt1 agonist, inhibited autophagic flux, resulting in oxidative stress, mitochondrial dysfunction (MtD) and apoptosis in QBC939 cells, which were attenuated by enhancing autophagy with rapamycin. On the contrary, inhibiting autophagic flux with 3-MA worsened all these effects in QBC939 cells. CONCLUSIONS: Taken together, our study for the first time identified FOXO1 as a potential therapeutic target to cure against human cholangiocarcinoma via regulation of autophagy, oxidative stress and MtD. PMID- 29466795 TI - Dialysate Creatinine Response Patterns During Peritoneal Equilibration Test and the Association Between Cardiovascular Mortality: Findings from a Prospective Cohort Study. AB - BACKGROUND/AIMS: During peritoneal equilibrium test (PET), intermediate measures of Dt/P (dialysate/plasma creatinine ratio), D0/P, D2/P and D4/P ratios might provide additional information regarding a patient's cardiovascular mortality. We aimed to characterise heterogeneity of dialysate creatinine response patterns based on three ratios and compare cardiovascular mortality risks by response patterns. METHODS: 3,477 patients initialising peritoneal dialysis (PD) between 2007-2015 were measured D0/P, D2/P and D4/P at baseline and 2-year cardiovascular mortality was defined as the primary outcome. Latent class mixed-effect models were fitted to identify distinct patterns of dialysate creatinine response. Multivariable Logistic regression model with adjustment of cardiometabolic factors were used to compare cardiovascular mortality by latent classes. RESULTS: The 1st latent class including 36% of participants was characterised by consistently increasing and high Dt/P ratios both at 2-hour and 4-hour. The 2nd class including 61% of participants characterised by sharply increased ratio at 2 hour and slightly increased ratio at 4-hour. The 3rd class included 3% of participants with decreased ratio at 2-hour and increased ratio at 4-hour. Comparing the 1st class, the lower cardiovascular mortality risk was identified in the 2nd and 3rd class with adjusted odds ratio 0.65 (95% confidence interval: 0.62-0.69) and 0.48 (0.41-0.57), respectively. CONCLUSION: Patients with decreased Dt/P ratio between 0-hour and 2-hour and low ratios at 2-hour and 4 hour tend to have low cardiovascular mortality. Latent class analysis seems to be a promising method to reveal unidentified subgroups that do not fit into the risk category defined by Dt/P ratio at 4-hour. PMID- 29466796 TI - Changes in Dietary Patterns and the Nutritional Status in Men in the Metallurgical Industry in Poland Over A 21-Year Period. AB - BACKGROUND/AIMS: The study was carried out to evaluate the changes in the eating habits and lipid parameters in a 21-year follow-up on a group of 435 men living in Poland. METHODS: The studied population was composed of the same subjects: a group of men who were first studied in the years 1987-1989 and in 2008-2010. The following data was gathered: body mass, body mass index (BMI), total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and triglyceride concentration in blood serum. RESULTS: The changes in the eating habits among the studied men registered throughout the 21-year period were positive since they showed a reduction in the caloric content of their diet (p < 0.001), lower total fat content (p < 0.001), total amount of carbohydrates (p < 0.001), sucrose (p < 0.001), iron (p < 0.001), and featured more vitamins: A (p < 0.002), B1 (p < 0.001), and C (p < 0.001). An adverse trend was observed in terms of constant calcium shortages in their food portions (ns). A 21-year follow-up of the studied group showed significant differences in terms of weight (p < 0.001), BMI (p < 0.001), and all cholesterol fractions (p < 0.001) in their blood serum, except cholesterol alone (ns). CONCLUSION: It is important to continue observing the dietary trends in the studied group, with the focus on the occurrence of potential changes in their bodies. PMID- 29466797 TI - A Prospective Cohort Study in Patients with Type 2 Diabetes Mellitus for Validation of Biomarkers (PROVALID) - Study Design and Baseline Characteristics. AB - BACKGROUND/AIMS: The prevalence of diabetes mellitus type 2 and kidney disease in these patients varies widely between European countries. METHODS: In addition to store bio-samples the "Prospective cohort study in patients with type 2 diabetes mellitus for validation of biomarkers" collects information on history, physical status, laboratory measurements and medication in 4000 patients with diabetes mellitus type 2, being taken care of at the primary level of healthcare in 5 European countries (Austria, Hungary, Netherlands, Poland and Scotland). Next to comparing the rate of loss of eGFR between the countries, a further objective of the PROVALID study is to determine the 5-year cumulative incidence of renal and cardiovascular outcomes. RESULTS: The mean age of the population recruited is 62.9+/-10 years, 54.6% are male and the mean BMI is 30.9+/-5.4 kg/m2. Metabolic control (median HBA1c 6.8 % (6.2; 7.5)) is achieved via administration of metformin in 67.4% of the patients and insulin in 30.3%. Median systolic and diastolic blood pressure at recruitment is 135 (125; 146) and 80 (72; 85) mmHg, 65.4% of subjects received RAAS blocking agents. Mean eGFR is 80.7+/-29.2 ml/min/1.73m2 and median baseline albumin/creatinine ratio 8.3 mg (IQR: 3.8 and 25.1). CONCLUSION: PROVALID will provide information on incidence and progression of renal and cardiovascular disease and therapy in patients with type 2 diabetes mellitus in different European countries. Thus, in contrast to many other cohort studies we will be able to associate national clinical practise pattern with outcome in this highly vulnerable patient population. PMID- 29466798 TI - Antithrombin III is a Novel Predictor for Contrast Induced Nephropathy After Coronary Angiography. AB - BACKGROUND/AIMS: Antithrombin III (AT III) is an important endogenous anticoagulant and has strong anti-inflammatory properties. Low ATIII activity is considered to be a predictor of poor outcomes in several conditions, including acute kidney injury after cardiac surgery. However, the association between the ATIII level and the occurrence of contrast induced nephropathy (CIN) has not been elucidated. In this study, our aim was to identify the potential predictive value of ATIII for CIN. METHODS: We enrolled a total of 460 patients who underwent coronary angiography (CAG) from January 2015 to December 2016 in coronary care units (CCU). ATIII activity in plasma collected before CAG was measured and <75% was considered low activity according to reference values. A cross-sectional study on CIN after CAG was conducted and the risk factors were analyzed. CIN was diagnosed according to the KDIGO guideline. RESULTS: Of these 460 patients undergoing CAG, 125 (27.17%) progressed to CIN. The incidence of CIN was significantly higher in patients with low ATIII activity compared to patients with normal ATIII activity (Pearson's chi-squared test P=0.002). As ATIII activity declined, the prevalence of CIN progressively increased, with the highest value (58.8%) in patients with an ATIII activity <60%. Moreover, the ATIII activity was significantly lower in CIN patients than in non-CIN patients (84.43+/-16.3% vs. 92.14+/-13.94%, P<0.001). After multivariable analysis, ATIII activity <75% remained a significant independent predictor of CIN (OR 2.207,95%CI [1.29-3.777]; P=0.004) as well as baseline serum creatinine (OR 1.009,95%CI [1.001-1.016]; P=0.026). CONCLUSIONS: Patients with low ATIII activity had a higher risk of developing CIN after CAG. The initial ATIII activity may be a novel independent predictor for CIN. PMID- 29466799 TI - Exogenous beta-Hydroxybutyrate Treatment and Neuroprotection in a Suckling Rat Model of Hypoxic-Ischemic Encephalopathy. AB - beta-Hydroxybutyrate (BHB) is a representative ketone body that may play a role in the mitigation of neonatal hypoxic-ischemic encephalopathy by altering energy metabolism. This study aimed to investigate the neuroprotective efficacy of exogenous BHB administration in a suckling rat model after hypoxia-ischemia (HI). Thirteen-day-old (P13) rat pups were subjected to 120 min of hypoxia according to the Rice-Vannucci model. BHB (5.0 mmol/kg, HI-BHB) or vehicle (0.9% saline, HI Veh) was administered 0, 2, 4, and 6 h after HI induction. Pathologic injury scores and the number of TUNEL-positive cells were evaluated on P15. Residual hemispheric volume was measured with T2-weighted MRI (on P27) and functional tests, such as the negative geotaxis test, rope suspension test, rotarod test, novel object recognition test, and cylinder test, were performed. Systemic ketosis (approx. 2.0-3.0 mM/L) was well tolerated by the rat pups with no difference in the mortality rate between both groups. Compared with the HI-Veh group, the HI-BHB group demonstrated significantly lower pathological scores as well as fewer TUNEL-positive cells. The intact residual hemispheric and hippocampal volumes were greater in the HI-BHB group than the HI-Veh group. However, the results of functional tests did not differ between both groups. Postischemic BHB administration reduced brain injury in suckling rats after HI. The safe clinical application of our animal model to human infants with HI requires further investigation. PMID- 29466800 TI - The Association Between Oxidative Stress Alleviation via Sulforaphane-Induced Nrf2-HO-1/NQO-1 Signaling Pathway Activation and Chronic Renal Allograft Dysfunction Improvement. AB - BACKGROUND/AIMS: Chronic renal allograft dysfunction (CRAD) is a leading cause of long-term renal allograft loss. Oxidative stress may account for the nonspecific interstitial fibrosis and tubular atrophy that occur in CRAD. An antioxidant intervention via Nrf2 signaling pathway activation might be a promising therapy for some kidney diseases. The present paper investigates whether there is an association between oxidative stress alleviation via sulforaphane-induced Nrf2-HO 1/NQO-1 signaling pathway activation and CRAD improvement. METHODS: F344 rat kidneys were orthotopically transplanted into Lewis rat recipients to establish CRAD models. Sulforaphane was administered at 1.5 mg/kg intraperitoneally once daily. Renal function and 24-hour urinary protein were monitored for variations for 24 weeks after transplantation. After 24 weeks, renal histopathology was evaluated according to the Banff criteria after hematoxylin and eosin, Masson's trichrome and periodic acid-Schiff stainings. Additionally, intrarenal oxidative stress was assessed by the indicators malondialdehyde, 8-isoprostane, oxidized low density lipoprotein and 8-hydroxy-2'-deoxyguanosine, as well as the activity levels of the antioxidant enzymes total superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase and gamma-glutamylcysteine synthetase. Nrf2, HO-1 and NQO-1 expression levels were determined via immunohistochemical and Western blot analyses. RESULTS: The sulforaphane-induced Nrf2-HO-1/NQO-1 signaling pathway activation, as demonstrated by immunohistochemical and Western blot analyses, delayed the progression of serum creatinine and blood urea nitrogen, particularly lowering the 24-hour urinary protein levels of CRAD. The semi-quantified histopathological changes were also alleviated. Evidence of oxidative stress alleviation, as indicated by a concurrent decrease in the indicators and sustained levels of antioxidant enzymes activity, was found in the renal allografts after sulforaphane intervention. CONCLUSION: Oxidative stress alleviation caused by continuous sulforaphane induced Nrf2-HO-1/NQO-1 signaling pathway activation is associated with functional and morphological improvements of CRAD. PMID- 29466801 TI - Benzodiazepines as a Monotherapy in Depressive Disorders: A Systematic Review. AB - BACKGROUND: The aim of this paper was to perform a systematic review and, when feasible, a meta-analysis of randomized controlled trials (RCT) which used benzodiazepines (BZD) as a monotherapy versus placebo, antidepressant drugs (AD), or both. METHODS: Keyword searches were conducted for identifying RCT comparing BZD and AD, and/or placebo in the treatment of depression, using electronic databases from their inception up to April 2017. We selected reports of RCT in which BZD were compared to AD and/or placebo in the treatment of adult patients with a primary diagnosis of depressive disorder or anxious depression. When feasible, data were subjected to meta-analysis. RESULTS: A total of 38 studies met the criteria for inclusion and were then included in the systematic review. Only 1 study concerned a newer AD, fluvoxamine. For the meta-analysis, we submitted data on response rate from 22 RCT, considering BZD versus placebo (8 comparisons) and BZD versus tricyclic antidepressants (TCA) (20 comparisons). There was a lack of significant differences as to response rate between BZD and placebo, as well as between BZD and TCA. Analysis of individual studies disclosed that, in more than half of the studies comparing BZD to TCA and/or placebo, BZD were significantly more effective than placebo and as effective as TCA. CONCLUSIONS: BZD are a therapeutic option in anxious depression and there are no indications that AD are preferable. There is a pressing need for RCT of adequate methodological quality and follow-up comparing BZD to second-generation AD and placebo in anxious depression.

AB - Healthy aging is associated with impairment in cognitive information processing. Several neuroimaging methods such as functional magnetic resonance imaging, positron emission tomography and near-infrared spectroscopy have been used to explore healthy and pathological aging by relying on hemodynamic or metabolic changes that occur in response to brain activity. Since electroencephalography (EEG) and magnetoencephalography (MEG) are able to measure neural activity directly with a high temporal resolution of milliseconds, these neurophysiological techniques are particularly important to investigate the dynamics of brain activity underlying neurocognitive aging. It is well known that age is a major risk factor for Alzheimer's disease (AD), and that synaptic dysfunction represents an early sign of this disease associated with hallmark neuropathological findings. However, the neurophysiological mechanisms underlying AD are not fully elucidated. This review addresses healthy and pathological brain aging from a neurophysiological perspective, focusing on oscillatory activity changes during the resting state, event-related potentials and stimulus-induced oscillatory responses during cognitive or motor tasks, functional connectivity between brain regions, and changes in signal complexity. We also highlight the accumulating evidence on age-related EEG/MEG changes and biological markers of brain neurodegeneration, including genetic factors, structural abnormalities on magnetic resonance images, and the biochemical changes associated with Abeta deposition and tau pathology. PMID- 29466803 TI - Grandiose and Vulnerable Narcissism in Borderline Personality Disorder. AB - BACKGROUND: Little is known about narcissistic traits in borderline personality disorder (BPD). This exploratory study aimed to illustrate the associations between total, grandiose, and vulnerable narcissism and gender, diagnostic features of BPD and narcissistic personality disorder (NPD), and psychopathology in BPD patients. SAMPLING AND METHODS: The Pathological Narcissism Inventory and psychometric measures for impulsivity, anger, borderline symptom severity, personality organization, depression, and rejection sensitivity were completed by 65 BPD patients. Statistical analyses were conducted using the t test, Pearson correlation, and multivariate regression analyses. RESULTS: Male BPD patients displayed higher narcissistic scores than females (p < 0.01). Grandiose narcissism showed a stronger association with NPD than with BPD (p < 0.01) while vulnerable narcissism was only associated with BPD (p < 0.01). Rejection sensitivity (p < 0.01) and depression (p < 0.001) predicted vulnerable narcissism. CONCLUSION: Vulnerable narcissism is closely associated with BPD and appears to be more dysfunctional than grandiose narcissism. A comprehensive consideration of both traits is recommended. Our results might help to generate hypotheses for further research on pathological narcissism in the spectrum of personality disorders. Future studies are advised to apply complementary measures and take new diagnostic approaches of DSM-5 and ICD-11 into account. PMID- 29466804 TI - Phenotypic Variability in Autosomal Dominant Familial Alzheimer Disease due to the S170F Mutation of Presenilin-1. AB - BACKGROUND: In rare cases, patients with Alzheimer disease (AD) present at an early age and with a family history suggestive of an autosomal dominant mode of inheritance. Mutations of the presenilin-1 (PSEN1) gene are the most common causes of dementia in these patients. Early-onset and particularly familial AD patients frequently present with variable non-amnestic cognitive symptoms such as visual, language or behavioural changes as well as non-cognitive, e.g. motor, symptoms. OBJECTIVE: To investigate the phenotypic variability in carriers of the PSEN1 S170F mutation. METHODS: We report a family with 4 patients carrying the S170F mutation of whom 2 underwent detailed clinical examinations. We discuss our current findings in the context of previously reported S170F cases. RESULTS: The clinical phenotype was consistent regarding initial memory impairment and early onset in the late twenties found in all S170F patients. There were frequent non amnestic cognitive changes and, at early stages of the disease, indications of a more pronounced disturbance of visuospatial abilities as compared to face and object recognition. Non-cognitive symptoms most often included myoclonus and cerebellar ataxia. A review of the available case reports indicates some phenotypic variability associated with the S170F mutation including different constellations of symptoms such as parkinsonism and delusions. CONCLUSION: The variable clinical findings associated with the S170F mutation highlight the relevance of atypical phenotypes in the context of research and under a clinical perspective. CSF sampling and detection of Abeta species may be essential to indicate AD pathology in unclear cases presenting with cognitive and motor symptoms at a younger age. PMID- 29466805 TI - Personality Disorder and Alcohol Use Disorder: An Overview. AB - BACKGROUND: Clinically, personality disorder (PD) commonly coexists with alcohol use disorder (AUD), although within mainstream mental health services both of these mental disorders are routinely overlooked. Despite a rich literature examining the interactions between AUD and personality functioning, personality traits, and PD, there remains conflicting evidence as to the degree of association and impact of one on the other. METHODS: A narrative review and a synthesis of the literature were done. RESULTS: The lifetime prevalence of AUD approaches 50% in some PD populations. The rates of PD in AUD populations are less clear but likely similar. Personality influences outcomes in AUD regardless of whether a categorical personality diagnosis or dimensional trait domain approach is taken. There are, however, no good data to inform clinicians on the impact of AUD on the outcomes of PD. Understanding the extent of this impact is complicated by the multiple tools used for diagnosis (of both PD and AUD) and the statistical methods used. Overall, caution is required in interpreting the data due to the quality of the current literature; however, comorbidity between the two disorders is likely significant and the impact of PD on AUD outcomes is sufficient to require consideration. CONCLUSIONS: From a research perspective, better agreement on both diagnoses and outcomes is urgently needed to improve the overall quality of the evidence. Clinically, despite the limitations in the literature, it is unacceptable for PD services to ignore AUD and for AUD services not to screen for PD. Both are likely to have an impact on health and functioning and should be considered in routine reviews. A better conceptualization of the putative mechanisms of this interaction, as well as an understanding of the neurobiology and reasons for the impact on treatment outcomes, will help to move the field forward. PMID- 29466806 TI - Vitamin D and Its Role in Neonatal Hypoxic-Ischemic Brain Injury. AB - Emerging evidence has demonstrated that vitamin D plays an important role in many adult neurologic disorders, but is also critical in neuronal development and pruning in the neonatal and pediatric populations. Neonates are at a particularly high risk of vitamin D deficiency, in part due to the high prevalence of maternal deficiency during pregnancy. Several preclinical studies have demonstrated that infants born to vitamin D-deficient mothers are at a high risk of developing neonatal brain injury, and recent clinical studies have shown that neonates with hypoxic-ischemic encephalopathy (HIE) tend to be vitamin D-deficient. There are limited data, however, on whether additional prenatal or postnatal supplementation may alter the prevalence or severity of neonatal HIE. This review examines the current data supporting the neuroprotective role of vitamin D, with a focus on how these findings may be translated to neonates with HIE. PMID- 29466807 TI - Sutureless Belt Loops versus Sutured Buckle Technique in Combination with Vitrectomy for Retinal Detachment Repair: A Comparative Analysis. AB - OBJECTIVE: To compare the anatomic and visual outcomes in primary rhegmatogenous retinal detachment repair involving combined pars plana vitrectomy (PPV)/scleral buckle (SB) using a sutureless belt loops technique versus a conventional sutured buckle technique. METHODS: This is a retrospective, consecutive, interventional, comparative case series study using patients treated for primary retinal detachment who underwent the SB procedure in combination with PPV. Details regarding anatomic and visual outcome were analyzed. RESULTS: Thirty-five eyes were included in this study: 18 eyes (18 patients) treated with combined PPV and SB performed using a sutureless belt loops technique (group A) and 17 eyes (17 patients) treated with combined PPV and SB sutured to the sclera (group B). Successful anatomic attachment and appropriate buckle height were achieved in all 35 cases. There was 1 case of redetachment in each group during the follow-up: 1/17 (5.9%) in group A and 1/18 (5.6%) in group B (p = 0.97). No cases of buckle infection, extrusion, or intrusion were noted during the follow-up period. CONCLUSION: SBs installed using a belt loops sutureless technique appear to be as safe and effective as those applied using conventional suturing for repair of retinal detachment, with similar anatomic and functional outcomes. PMID- 29466808 TI - Impact of Green Tea Catechin ECG and Its Synthesized Fluorinated Analogue on Prostate Cancer Cells and Stimulated Immunocompetent Cells. AB - Among the known or suspected risk factors, inflammation plays an important role in infectious and non-infectious pathways leading to cancer. Green tea polyphenols have been associated with reducing inflammation and protection against carcinogenesis, especially in prostate cancer. While most of the research in this field, so far, has focussed on epigallocatechin-3-O-gallate only, we studied epicatechin-3-O-gallate, the second most abundant green tea polyphenol with essential therapeutic potential, to obtain a more detailed understanding of its anti-tumor and anti-inflammatory action. Furthermore, to improve the bioactivity of (-)-epicatechin-3-O-gallate, we synthesized a difluoro analogue, called (-)-5,7-difluoro-epicatechin-3-O-gallate. Both compounds reduced cell proliferation of human primary inflammatory lymphocytes in an apoptosis-specific fashion, while (-)-5,7-difluoro-epicatechin-3-O-gallate had a significantly higher activity compared to the natural product (-)-epicatechin-3-O-gallate. Treatment of low-metastatic LNCaP and high-metastatic PC-3 prostate cancer cells with (-)-epicatechin-3-O-gallate and (-)-5,7-difluoro-epicatechin-3-O-gallate demonstrated a dose-dependent inhibition of cell viability in the low micromolar range. These effects suggest that (-)-epicatechin-3-O-gallate and the more effective (-)-5,7-difluoro-epicatechin-3-O-gallate could be therapeutically used to inhibit tumorigenesis during initiation, promotion, and progression by diminishing the amount of inflammation due to a reduction of inflammatory lymphocytes. Further studies are needed to prove this in in vivo experiments. PMID- 29466809 TI - An Update on the Biological Activities of Euterpe edulis (Jucara). AB - The palm tree Euterpe edulis, known as jucara, produces spherical and purple fruits, similar to those of the Euterpe oleracea and Euterpe precatoria palm trees, from which the common name acai originates. Jucara fruit has been gaining prominence in the scientific world for its interesting nutritional composition, which is rich in antioxidants, and for its sustainable production model. Recently, relevant biological activities have been associated with the jucara fruit, and its use in alimentation has become an important nutritional, environmental, and economic alternative. The aim of this review is to compile recent scientific data about the phytochemical characterization and biological activities of E. edulis. A review of the literature was conducted in two electronic databases, Medline and Science Direct. The eligibility criteria were as follows: phytochemicals characterize of the E. edulis fruits and evaluate biological effects in vitro or in vivo with pulp, extract, juice, or product of jucara fruits. Investigations were excluded if they used other parts of the plant (seeds), did not assess biological activities, or have tested methodologies for compound extraction. From the identified reports, 25 articles were eligible for this study. The promotion of health benefits related to jucara fruits seems to have improved antioxidant activity in vivo, benefits to lipid and glycemic profiles, and modulation of inflammatory status in experimental studies in animals.

AB - Digital patient photography and morphing software have become an important part of rhinoplasty over the past few decades. Presented is a novel technology incorporating 3D photography and printing to produce life-size models for use in patient evaluation and treatment. Surveys were conducted to assess patient response and were universally positive. Early surgeon experience also indicates benefit for intraoperative use. Three-dimensional printing and modeling is a new technology that has exciting applications for rhinoplasty and facial plastic surgery. PMID- 29466811 TI - Facial Asymmetry: Brow and Ear Position. AB - The purpose of the current study was to analyze brow and ear position, and examine the relationship between these structures in patients presenting for blepharoplasty evaluation. A retrospective chart review was performed, which included all patients presenting to one oculoplastic physician for a blepharoplasty evaluation from November, 2012 to March, 2014. The prevalence of brow ptosis and brow and ear asymmetry was calculated; the proportional distribution was determined, and chi-square analysis and the z-test of proportions were used to calculate the significance. Institutional Review Board approval was obtained for this study. A total of 133 patients met the inclusion criteria. Some degree of brow ptosis was noted in 83% of patients. Brow asymmetry was found in 88% of patients, and ear asymmetry in 77%. Of those patients who had asymmetry, 61% had the right brow lower and 75% had the right ear lower; 73% of all patients had the brow and ear lower on the same side (p < 0.001). In this study, brow ptosis and asymmetry were quite common. In addition, the side of the lower brow correlated strongly with the side of the lower ear, and the right side structures were lower more often than the left. Patients presenting for blepharoplasty evaluation may have an element of generalized facial asymmetry which includes the brows and ears. These observations can be important for preoperative planning and patient counseling. PMID- 29466812 TI - [Non-Small Cell Lung Cancer - Development of Parallel Mechanisms of Resistance].

AB - BACKGROUND: Interstitial lung diseases (ILD) encompass different heterogeneous, mainly chronic diseases of the pulmonary interstitium and/or alveoli with known and unknown reasons. The diagnostic of ILD is challenging and should be performed interdisciplinary. The medical history is of major importance and therefore, in German-speaking countries the Frankfurter Bogen (published in 1985) was utilised to scrutinise the medical history of the patient. This by now more than 30-years old questionnaire requires a revision with regard to content and language. METHOD: Under the auspices of the clinical section of the DGP the new Interstitial Lung Disease Patient Questionnaire was developed in collaboration amongst pulmonologist, occupational medicine physicians and psychologists and supported by patient support groups. The questionnaire was finally optimised linguistically with the help of patients. RESULTS: The newly developed patient questionnaire for interstitial and rare lung diseases encompasses different domains: initial and current symptoms, medical history questions including prior drug treatments, previous pulmonary and extrapulmonary diseases, potential exposition at home, work and leisure time as well as family history and travelling. CONCLUSION: The newly developed questionnaire can facilitate the diagnosis in patients with suspicion on interstitial lung disease in clinical routine.

PMID- 29466818 TI - Development and Validation of a Natural Language Processing Tool to Identify Patients Treated for Pneumonia across VA Emergency Departments. AB - BACKGROUND: Identifying pneumonia using diagnosis codes alone may be insufficient for research on clinical decision making. Natural language processing (NLP) may enable the inclusion of cases missed by diagnosis codes. OBJECTIVES: This article (1) develops a NLP tool that identifies the clinical assertion of pneumonia from physician emergency department (ED) notes, and (2) compares classification methods using diagnosis codes versus NLP against a gold standard of manual chart review to identify patients initially treated for pneumonia. METHODS: Among a national population of ED visits occurring between 2006 and 2012 across the Veterans Affairs health system, we extracted 811 physician documents containing search terms for pneumonia for training, and 100 random documents for validation. Two reviewers annotated span- and document-level classifications of the clinical assertion of pneumonia. An NLP tool using a support vector machine was trained on the enriched documents. We extracted diagnosis codes assigned in the ED and upon hospital discharge and calculated performance characteristics for diagnosis codes, NLP, and NLP plus diagnosis codes against manual review in training and validation sets. RESULTS: Among the training documents, 51% contained clinical assertions of pneumonia; in the validation set, 9% were classified with pneumonia, of which 100% contained pneumonia search terms. After enriching with search terms, the NLP system alone demonstrated a recall/sensitivity of 0.72 (training) and 0.55 (validation), and a precision/positive predictive value (PPV) of 0.89 (training) and 0.71 (validation). ED-assigned diagnostic codes demonstrated lower recall/sensitivity (0.48 and 0.44) but higher precision/PPV (0.95 in training, 1.0 in validation); the NLP system identified more "possible treated" cases than diagnostic coding. An approach combining NLP and ED-assigned diagnostic coding classification achieved the best performance (sensitivity 0.89 and PPV 0.80). CONCLUSION: System-wide application of NLP to clinical text can increase capture of initial diagnostic hypotheses, an important inclusion when studying diagnosis and clinical decision-making under uncertainty.

AB - BACKGROUND: Recent advances in computer vision and wearable technology have created an opportunity to introduce mobile therapy systems for autism spectrum disorders (ASD) that can respond to the increasing demand for therapeutic interventions; however, feasibility questions must be answered first. OBJECTIVE: We studied the feasibility of a prototype therapeutic tool for children with ASD using Google Glass, examining whether children with ASD would wear such a device, if providing the emotion classification will improve emotion recognition, and how emotion recognition differs between ASD participants and neurotypical controls (NC). METHODS: We ran a controlled laboratory experiment with 43 children: 23 with ASD and 20 NC. Children identified static facial images on a computer screen with one of 7 emotions in 3 successive batches: the first with no information about emotion provided to the child, the second with the correct classification from the Glass labeling the emotion, and the third again without emotion information. We then trained a logistic regression classifier on the emotion confusion matrices generated by the two information-free batches to predict ASD versus NC. RESULTS: All 43 children were comfortable wearing the Glass. ASD and NC participants who completed the computer task with Glass providing audible emotion labeling (n = 33) showed increased accuracies in emotion labeling, and the logistic regression classifier achieved an accuracy of 72.7%. Further analysis suggests that the ability to recognize surprise, fear, and neutrality may distinguish ASD cases from NC. CONCLUSION: This feasibility study supports the utility of a wearable device for social affective learning in ASD children and demonstrates subtle differences in how ASD and NC children perform on an emotion recognition task.

AB - OBJECTIVES: To report on the process of updating the German Pension Insurers' rehabilitation therapy standards (RTS) from 2013 to 2015. METHODS: Four methodical approaches were taken to gather evidence: a) systematic literature searches, b) the formation of expert groups, expert workshops, and online discussion forums to bring together the experiences from clinicians and patients, c) an analysis of the latest KTL data to understand the extent to which the RTS are currently being fulfilled, and d) conceptual consideration of the significance of current developments in rehabilitation in light of the RTS revision. RESULTS: There are now updated versions of all 9 RTS. Over half of the therapy modules are based on scientific evidence. Other modules are based on clinical experience with good clinical-practice standards. The scientific evidence has not changed much overall in the last few years, although there are some indications of higher evidence levels. CONCLUSION: The revised RTS can make a positive contribution to ensuring that rehabilitation is of high quality. Further research is needed to increase the level of evidence - especially regarding the intensity of therapy. PMID- 29466823 TI - Analytical and Pharmacological Challenges in Cannabis Research. PMID- 29466822 TI - ? AB - Alternative diets (AD) differ from the current common mixed diet; AD are recommended as a permanent diet. These diets are based on ethical, philosophical and health promoting principles and lead to very different recommendations for food selection. Even within a particular AD there is usually a broad spectrum of versions, so that a general evaluation is only possible to a limited extent. This is also true for single AD. Vegetarian diets and partly paleo-diets have been investigated to a reasonable extent. Plant based diets are appropriate as permanent diets and offer health benefits as compared with currently practiced diets (risk reduction of cancers by 10-18% and of heart diseases by 30%; favorable effect on blood pressure and lipid profile; no risk reduction on cancer and total mortality). Vegan diets have to be critically assessed: they are linked to an increased risk of deficits for single nutrients (vitamin B12, iodine and as the case may be. calcium and long chain omega-3 fatty acids), if suitable supplements or fortified foods are not consumed. PMID- 29466824 TI - QTc Time Correlates with Amitriptyline and Venlafaxine Serum Levels in Elderly Psychiatric Inpatients. AB - INTRODUCTION: Many antidepressants cause QT prolongation but the classification of cardiac risk of these drugs varies markedly in different published lists. This retrospective study analyzed the correlation of QTc time with amitriptyline and venlafaxine serum level in elderly psychiatric inpatients. METHODS: Elderly inpatients aged>=65 years for whom venlafaxine or amitriptyline serum level had been measured were selected retrospectively from a therapeutic drug monitoring database and screened for an electrocardiogram measurement at the time of blood withdrawal. The correlation of amitriptyline or venlafaxine serum levels with QTc time was examined by using Pearson's correlation analysis. RESULTS: Amitriptyline serum levels (n=11) correlated significantly with QTc time (r=0.918, p<0.001, CI 95%). Venlafaxine serum levels (n=27) also correlated significantly with QTc time (r=0.382, p<0.05, CI 95%). DISCUSSION: Amitriptyline and venlafaxine induce QT prolongation depending on drug concentrations in blood. Its extent, however, is very low when drug serum levels are within the therapeutic range. Future pharmacokinetic studies that correlate drug serum level and QT time should classify the cardiac risk of drugs based on the grade of the regression line in relation to the therapeutic range. PMID- 29466825 TI - Responses to warnings about the impact of eating disorders on fertility: a qualitative study. AB - Eating disorders (EDs) have often been discussed as a risk to reproductive health. But existing research is quantitative in nature, paying no attention to issues of patient experience. In discussing data from 24 semi-structured interviews, this article draws on sociological approaches to medical 'risk' and feminist approaches to EDs to explore how women with experience of an ED responded to fertility warnings within treatment contexts. In doing so, it is suggested that responses to fertility warnings offer unique insight into the potentially damaging limitations of biomedical approaches to eating problems and their focus on EDs as individual 'pathologies' (rather than culturally embedded expressions of gendered embodiment). At best warnings are seen as making problematic assumptions about the aspirations of female patients, which may curtail feelings of agency and choice. At worst, they may push women further into destructive bodily and eating practices, and silence the distress that may be articulated by an ED.

In this study we assessed the regenerative effect of microcurrent electrical stimulation (MES) on gastrocnemius muscle (GCM) atrophy induced by immobilization by cast (IC) in rabbits. METHODS: Fifteen rabbits were divided into 3 groups: IC (group 1); IC and free re-ambulation for 2 weeks after cast removal (CR) (group 2); and IC and MES for 2 weeks after CR (group 3). We evaluated clinical parameters (calf circumference, compound muscle action potential of tibial nerve, and thickness of GCM by ultrasound), histomorphometric data (muscle composition and cross sectional area), and immunohistochemistry. RESULTS: Mean atrophic changes in clinical parameters in group 3 were significantly less than those in groups 1 and 2 (P < 0.05). Histomophometric and immunohistochemical parameters in group 3 were significantly greater than those in groups 1 and 2, respectively (P < 0.05).

AB - INTRODUCTION: We describe a new nerve conduction study technique with reference values for the 3 branches of the supraclavicular nerve (SCN) in young healthy subjects and application of it in 2 patients. METHODS: The recording electrode was placed on the posterior border of the sternocleidomastoid muscle, 6-7 cm from the sternoclavicular joint. SCN branches were stimulated below the clavicle, 2.5, 7, and 10.5 cm lateral to the sternoclavicular joint. RESULTS: Twenty healthy volunteers (10 men), 19-38 years, mean 25.9 years (SD 6.3), and 2 patients with SCN lesions were studied. The mean conduction velocities of the SCN branches were 70-78 m/s (SD 8-10 m/s), and amplitudes 3-4 uV (SD 0.9-2.0 uV). There were no side-to-side or gender differences. DISCUSSION: The 3 SCN branches could be studied in all subjects. We provide reference values for young subjects. This new method was useful in verifying SCN lesions in 2 patients.

AB - INTRODUCTION: Our objective in this study was to assess the psychometric properties of the English (UK and USA) version of the Pediatric Quality of Life Inventory 3.0 Neuromuscular Module (PedsQL NMM) administered to patients with Duchenne muscular dystrophy (DMD). METHODS: Patients with DMD from the UK and the US completed the PedsQL NMM online. The psychometric properties of the instrument were examined using Rasch analysis. RESULTS: A total of 278 patients completed the PedsQL NMM. Model misfit was identified for 6 of 25 items (item fit residual: mean 0.162, standard deviation [SD] 2.333), 22 of 25 items displayed disordered thresholds, and item dependency was high. The mean person fit residual was estimated at -0.183 (SD 1.475). The Person Separation Index and Cronbach's alpha were estimated at 0.904 and 0.915, respectively. DISCUSSION: The English version of the PedsQL NMM may not be a valid measure of health-related quality of life in patients with DMD. Muscle Nerve 58: 367-373, 2018.

AB - INTRODUCTION: Quality of life (QOL) has been poorly characterized among patients with myasthenia gravis (MG) other than assessments performed within the clinical setting. METHODS: Patients age >= 18 years who were diagnosed with MG and registered with the MG patient registry between July 1, 2013, and June 30, 2016, were included. Demographic information, disease related history, and QOL were compared between men and women using multivariable analysis. RESULTS: A total of 1,315 subjects (827 women) were included. Women were significantly younger, had a younger age at symptom onset, and were more likely to have thymoma and thymectomy. The 15-item Myasthenia Gravis Quality of Life scale (MG-QOL15) was significantly worse in women. MG-QOL15 score was comparable between women who had thymectomy and men with or without thymectomy. DISCUSSION: QOL among MG patients is worse in women compared with men, but this disparity is eliminated in women who have undergone thymectomy. Muscle Nerve, 2018.

AB - INTRODUCTION: Amyotrophic lateral sclerosis (ALS) is a debilitating neurologic disorder with poor survival rates and no clear biomarkers for disease diagnosis and prognosis. METHODS: We compared serum microRNA (miRNA) expression from patients with ALS with healthy controls and patients with multiple sclerosis and Alzheimer disease. We also correlated miRNA expression in cross-sectional and longitudinal cohorts of ALS patients with clinical parameters. RESULTS: We identified 7 miRNAs (miR-192-5p, miR-192-3p, miR-1, miR-133a-3p, miR-133b, miR 144-5p, miR-19a-3p) that were upregulated and 6 miRNAs (miR-320c, miR-320a, let 7d-3p, miR-425-5p, miR-320b, miR-139-5p) that were downregulated in patients with ALS compared with healthy controls, patients with Alzheimer disease, and patients with multiple sclerosis. Changes in 4 miRNAs (miR-136-3p, miR-30b-5p, miR-331-3p, miR-496) correlated positively and change in 1 miRNA (miR-2110) correlated negatively with changes in clinical parameters in longitudinal analysis. DISCUSSION: Our findings identified serum miRNAs that can serve as biomarkers for ALS diagnosis and progression. Muscle Nerve 58: 261-269, 2018. PMID- 29466832 TI - Pathogen spillover during land conversion. AB - Pathogen spillover from wildlife to domestic animals and humans, and the reverse, has caused significant epidemics and pandemics worldwide. Although pathogen emergence has been linked to anthropogenic land conversion, a general framework to disentangle underlying processes is lacking. We develop a multi-host model for pathogen transmission between species inhabiting intact and converted habitat. Interspecies contacts and host populations vary with the proportion of land converted; enabling us to quantify infection risk across a changing landscape. In a range of scenarios, the highest spillover risk occurs at intermediate levels of habitat loss, whereas the largest, but rarest, epidemics occur at extremes of land conversion. This framework provides insights into the mechanisms driving disease emergence and spillover during land conversion. The finding that the risk of spillover is highest at intermediate levels of habitat loss provides important guidance for conservation and public health policy.

AB - A 13-year-old male presented with neoaortic root dilatation and severe aortic valve regurgitation 13 years following an arterial switch operation. The valve cusps were unbalanced due to an enlarged non-coronary cusp. A valve-sparing reimplantation with a cusp plication was performed which resulted in a competent valve with trivial regurgitation. Thus, even in an unbalanced cusp, valve-sparing reimplantation can be used for neoaortic root dilatation and valve regurgitation after an arterial switch operation. PMID- 29466834 TI - Central and Peripheral Expression of DNA Double-Strand Breaks in Human and Mouse Tissues. AB - Mammalian cells accumulate DNA lesions when they undergo phases of the cell cycle or during normal cellular activity. In this regard, several DNA repair signaling pathways have evolved to maintain genome stability and avoid the potential acquisition of mutations. To define and further characterize the expression of DNA double-strand breaks in humans and mice, we used immunocytochemistry to localize a DNA damage signal within the spatial confines of the cell nucleus. We show that DNA double-strand breaks are abundantly expressed in postmitotic neurons of the human and mouse brain. Notably, DNA double-strand breaks are present in human hypothalamic and mouse striatal and hippocampal cells, with stable expression of the nuclear signal detected throughout the mammalian brain. Analysis of the mouse tongue, heart, and testis shows that expression of DNA double-strand breaks is only demonstrated in circumscribed populations of peripheral cells. These data suggest that levels of DNA double-strand breaks are tissue-specific with the tongue, heart and testicular tissue having different thresholds of DNA repair and DNA damage from those outlined at the brain level.

AB - Epithelial-mesenchymal transition (EMT) is an important process that mediates organ development and wound healing, and in pathological contexts, it can contribute to the progression of fibrosis and cancer. During EMT, cells exhibit marked changes in cytoskeletal organization and increased expression of a variety of actin associated proteins. Here, we sought to determine the role of caldesmon in mediating EMT in response to transforming growth factor (TGF)-beta1. We find that the expression level and phosphorylation state of caldesmon increase as a function of time following induction of EMT by TGFbeta1 and these changes in caldesmon correlate with increased focal adhesion number and size and increased cell contractility. Knockdown and forced expression of caldesmon in epithelial cells reveals that caldesmon expression plays an important role in regulating the expression of the myofibroblast marker alpha smooth muscle actin. Results from these studies provide insight into the role of cytoskeletal associated proteins in the regulation of EMT and may suggest ways to target the cell cytoskeleton for regulating EMT processes.

AB - OBJECTIVE: Voltage-gated sodium (Na+ ) channels underlie action potential generation and propagation and hence are central to the regulation of excitability in the nervous system. Mutations in the genes SCN1A, SCN2A, and SCN8A, encoding the Na+ channel pore-forming (alpha) subunits Nav1.1, 1.2, and 1.6, respectively, and SCN1B, encoding the accessory subunit beta1 , are established causes of genetic epilepsies. SCN3A, encoding Nav1.3, is known to be highly expressed in brain, but has not previously been linked to early infantile epileptic encephalopathy. Here, we describe a cohort of 4 patients with epileptic encephalopathy and heterozygous de novo missense variants in SCN3A (p.Ile875Thr in 2 cases, p.Pro1333Leu, and p.Val1769Ala). METHODS: All patients presented with treatment-resistant epilepsy in the first year of life, severe to profound intellectual disability, and in 2 cases (both with the variant p.Ile875Thr), diffuse polymicrogyria. RESULTS: Electrophysiological recordings of mutant channels revealed prominent gain of channel function, with a markedly increased amplitude of the slowly inactivating current component, and for 2 of 3 mutants (p.Ile875Thr and p.Pro1333Leu), a leftward shift in the voltage dependence of activation to more hyperpolarized potentials. Gain of function was not observed for Nav1.3 variants known or presumed to be inherited (p.Arg1642Cys and p.Lys1799Gln). The antiseizure medications phenytoin and lacosamide selectively blocked slowly inactivating over transient current in wild-type and mutant Nav1.3 channels. INTERPRETATION: These findings establish SCN3A as a new gene for infantile epileptic encephalopathy and suggest a potential pharmacologic intervention. These findings also reinforce the role of Nav1.3 as an important regulator of neuronal excitability in the developing brain, while providing additional insight into mechanisms of slow inactivation of Nav1.3.

AB - The longstanding biotic interactions hypothesis predicts that herbivore pressure declines with latitude, but the evidence is mixed. To address gaps in previous studies, we measured herbivory and defence in the same system, quantified defence with bioassays, and considered effects of leaf age. We quantified herbivory and defence of young and mature leaves along a continental gradient in eastern North America in the native herb Phytolacca americana L. Herbivory in the field declined with latitude and was strongly correlated with lepidopteran abundance. Laboratory bioassays revealed that leaf palatability was positively correlated with latitude of origin. Young leaves were more damaged than mature leaves at lower latitudes in the field, but less palatable in bioassays. Both defence and palatability displayed non-linear latitudinal patterns, suggesting potential mechanisms based on biological or climatic thresholds. In sum, observational and experimental studies find patterns consistent with high herbivore pressure and stronger plant defences at lower latitudes.

AB - OBJECTIVE: To determine relationships of memory complaints to cognitive function and decline, incident dementia, and neurodegenerative and other neuropathologies, as well as the population-attributable risk for dementia in older black and white persons. METHODS: A total of 4,015 community-based persons (28% black; 74% women; mean baseline age = 78 years) were enrolled in 1 of 4 longitudinal cohort studies, and another 2,937 in a population-based cohort. Memory scores, assessed using 2 questions (5-point Likert scales) were categorized as complaints present or absent. Global cognition and 5 cognitive domains were derived from annual neuropsychological tests. Dementia was assessed from these tests and additional data. Neuropathologic data were available for 1,350 deceased subjects with brain autopsies. Regression and mixed effects models were used to examine relationships of memory complaints to cognition and neuropathology. RESULTS: Baseline memory complaints (n = 1,310; 33% of 4,015) were associated with lower cognition and faster decline in all domains (global score estimate = -0.032, standard error = 0.004, p < 0.0001), during a mean follow-up of 6 (standard deviation = 2) years. Persons with memory complaints had higher dementia risk (hazard ratio = 1.64, 95% confidence interval [CI] = 1.42-1.89) and odds of pathologic Alzheimer disease (odds ratio [OR] = 1.96, 95% CI = 1.51-2.54), neocortical Lewy bodies (OR = 2.47, 95% CI = 1.54-3.96), and other neurodegenerative pathologies. Results for dementia risk were similar among blacks and whites. Among 2,937 older persons in a population-based cohort with similar data, the population-attributable risk for incident dementia due to memory complaints was 14.0% (95% CI = 2.6-23.0), and did not vary between the black and white groups. INTERPRETATION: Memory complaints are common in older black and white persons, and relate to cognitive decline, dementia risk, and neurodegenerative pathologies. Ann Neurol 2018;83:718-729.

PMID- 29466841 TI - Seizures and disturbed brain potassium dynamics in the leukodystrophy megalencephalic leukoencephalopathy with subcortical cysts. AB - OBJECTIVE: Loss of function of the astrocyte-specific protein MLC1 leads to the childhood-onset leukodystrophy "megalencephalic leukoencephalopathy with subcortical cysts" (MLC). Studies on isolated cells show a role for MLC1 in astrocyte volume regulation and suggest that disturbed brain ion and water homeostasis is central to the disease. Excitability of neuronal networks is particularly sensitive to ion and water homeostasis. In line with this, reports of seizures and epilepsy in MLC patients exist. However, systematic assessment and mechanistic understanding of seizures in MLC are lacking. METHODS: We analyzed an MLC patient inventory to study occurrence of seizures in MLC. We used two distinct genetic mouse models of MLC to further study epileptiform activity and seizure threshold through wireless extracellular field potential recordings. Whole-cell patch-clamp recordings and K+ -sensitive electrode recordings in mouse brain slices were used to explore the underlying mechanisms of epilepsy in MLC. RESULTS: An early onset of seizures is common in MLC. Similarly, in MLC mice, we uncovered spontaneous epileptiform brain activity and a lowered threshold for induced seizures. At the cellular level, we found that although passive and active properties of individual pyramidal neurons are unchanged, extracellular K+ dynamics and neuronal network activity are abnormal in MLC mice. INTERPRETATION: Disturbed astrocyte regulation of ion and water homeostasis in MLC causes hyperexcitability of neuronal networks and seizures. These findings suggest a role for defective astrocyte volume regulation in epilepsy. Ann Neurol 2018;83:636-649.

PMID- 29466845 TI - Duodenal Niemann-Pick C1-like 1 expression was negatively correlated with liver X receptor expression in nonalcoholic fatty liver disease. AB - Background/Aims: Intestinal cholesterol absorption includes intestinal Niemann Pick C1-like 1 (NPC1L1) and is an important target pathway in nonalcoholic fatty liver disease (NAFLD). We investigated the expression of NPC1L1 and its correlation with liver X receptor (LXR) expression in peripheral mononuclear (PMN) cells in patients with NAFLD. Methods: We evaluated intestinal expression of NPC1L1 in 25 NAFLD patients and 28 healthy controls. We calculated the mRNA expression levels of LXR and farnesoid X receptor (FXR), which are master players of cholesterol metabolism in PMN cells. The protein expression of ABCA1, ABCG5/8, NPC1L1, SREBP, LXR, FXR, and CD36 was measured on tissue samples from the duodenum and ileum. Results: The expression of LXR (p = 0.01) and FXR (p = 0.03) in PMN cells was increased in the NAFLD group compared to the control group. Duodenal NPC1L1 decreased in the NAFLD group compared to the healthy controls (3.38 +/- 1.4 vs. 2.42 +/- 1.2, p = 0.05). NPC1L1 expression in the duodenum was negatively correlated with LXR expression in PMN cells. Expression of LXR and FXR in the ileum was also negatively correlated with the expression of LXR in PMN cells. Conclusions: Duodenal NPC1L1 expression was decreased in NAFLD and was negatively correlated with LXR expression in PMN cells. PMID- 29466846 TI - Utility of shear wave elastography to detect papillary thyroid carcinoma in thyroid nodules: efficacy of the standard deviation elasticity. AB - Background/Aims: The aim of this study was to address the role of the elasticity index as a possible predictive marker for detecting papillary thyroid carcinoma (PTC) and quantitatively assess shear wave elastography (SWE) as a tool for differentiating PTC from benign thyroid nodules. Methods: One hundred and nineteen patients with thyroid nodules undergoing SWE before ultrasound-guided fine needle aspiration and core needle biopsy were analyzed. The mean (EMean), minimum (EMin), maximum (EMax), and standard deviation (ESD) of SWE elasticity indices were measured. Results: Among 105 nodules, 14 were PTC and 91 were benign. The EMean, EMin, and EMax values were significantly higher in PTCs than benign nodules (EMean 37.4 in PTC vs. 23.7 in benign nodules, p = 0.005; EMin 27.9 vs. 17.8, p = 0.034; EMax 46.7 vs. 31.5, p < 0.001). The EMean, EMin, and EMax were significantly associated with PTC with diagnostic odds ratios varying from 6.74 to 9.91, high specificities (86.4%, 86.4%, and 88.1%, respectively), and positive likelihood ratios (4.21, 3.69, and 4.82, respectively). The ESD values were significantly higher in PTC than in benign nodules (6.3 vs. 2.6, p < 0.001). ESD had the highest specificity (96.6%) when applied with a cut-off value of 6.5 kPa. It had a positive likelihood ratio of 14.75 and a diagnostic odds ratio of 28.50. Conclusions: The shear elasticity index of ESD, with higher likelihood ratios for PTC, will probably identify nodules that have a high potential for malignancy. It may help to identify and select malignant nodules, while reducing unnecessary fine needle aspiration and core needle biopsies of benign nodules. PMID- 29466847 TI - Costs and clinical outcomes of patients with diffuse large B-cell lymphoma in first remission: role of PET/CT surveillance. AB - Background/Aims: The role of [18F]-f luorodeoxyglucose positron emission tomography-computed tomography (PET/CT) in patients with diffuse large B-cell lymphoma (DLBCL) in first remission is unclear. Methods: Medical costs within the first 3 years of treatment completion and clinical outcomes of 118 patients with DLBCL in first remission with and without surveillance PET/CT (PET/CT [+] group [n = 76] and PET/CT [-] group [n = 42], respectively) were retrospectively analyzed. Results: In a propensity matched cohort with adjustment for International Prognostic Index risk and relapse, the PET/CT (+) group was shown to have similar medical costs as the PET/CT (-) group. Relapse-free survival (RFS) and overall survival (OS) were comparable between the two groups (median RFS not reached [NR] for both groups, p = 0.133; median OS NR, p = 0.542). Among 76 patients with surveillance PET/CT, 31 (40.8%) had findings suggestive of recurrence and 16 of these (51.6%) were later confirmed to have recurrent disease. Fifteen patients (48.4%) were confirmed to not have recurrence after follow-up CT or PET/CT evaluation (n = 10) and biopsy (n = 4). None of the patients with negative PET/CT findings had disease recurrence. Sensitivity, specificity, positive predictive value, and negative predictive value of PET/CT for detection of recurrence were 1, 0.75, 0.52, and 1, respectively. Conclusions: Surveillance PET/CT resulted in similar clinical outcomes and medical costs compared to no surveillance PET/CT. Approximately half of patients with PET/CT findings of recurrence had no recurrence after follow-up imaging and biopsy, which would not have been carried out if PET/CT had not been performed in the first place. PMID- 29466848 TI - Factors associated with treatment interruption in elderly patients with cancer. AB - Background/Aims: This study was conducted to identify risk factors that predict vulnerability to cancer therapy on the basis of the clinical, geriatric, and quality of life assessment before starting treatment in elderly patients. Methods: Seventy-five patients aged 65 years and over with newly diagnosed stage IV solid cancer receiving chemotherapy were analyzed. Clinical and laboratory data were collected. The geriatric assessment was performed using the Korean versions of the Modified Barthel Index, Instrumental Activities of Daily Living, Mini-Mental State Examination, and Geriatric Depression Scale. The European Organisation for Research and Treatment of Cancer Quality-of-Life Core Questionnaire (EORTC-QLQ-C30) was also performed. Results: Forty-one patients stopped cancer treatment during or after the end of first-line therapy and were classified as the treatment interruption group. By univariate analysis, treatment interruption was associated with metastases to >= 2 distant sites, lower albumin level, lower EORTC-QLQ-C30 physical and role functioning scores, and higher EORTC QLQ-C30 fatigue and appetite loss symptom scores. By multivariate analysis, treatment interruption was significantly associated with low score for the EORTC QLQ-C30 physical functioning scale (odds ratio [OR], 1.020; 95% confidence interval [CI], 1.002 to 1.039; p = 0.030), and >= 2 sites of distant metastases (OR, 2.965; 95% CI, 1.012 to 8.681; p = 0.047). Conclusions: The EORTC-QLQ-C30 physical functioning score and metastases to >= 2 organs, which indicate a poor physical functional status and metastatic high tumor burden, were significantly associated with interruption of first-line treatment in elderly patients with cancer. PMID- 29466849 TI - Predictors of postoperative infectious complications in liver transplant recipients: experience of 185 consecutive cases. AB - Background/Aims: Infections following liver transplant (LT) remain a major cause of mortality. This study was conducted to evaluate risk factors for infection and to review clinical characteristics. METHODS: Medical records of patients who underwent LT from 2010 to 2014 were retrospectively analyzed. Binary logistic regression analysis was used to investigate risk factors of infection. Kaplan Meier analysis was used to predict prognosis of infected and non-infected groups. RESULTS: Of 185 recipients, 89 patients experienced infectious complications. The median follow-up period was 911 days (range, 9 to 2,031). The infected group had higher 1-year mortality (n = 22 [24.7%] vs. n = 8, [8.3%], p = 0.002), and longer postoperative admission days (mean: 53.7 +/- 35.8 days vs. 28.3 +/- 13.0 days, p < 0.001), compared to the non-infected group. High preoperative Model for End Stage Liver Disease (MELD) score (odds ratio [OR], 1.057; 95% confidence interval [CI], 1.010 to 1.105; p = 0.016), deceased-donor type (OR, 5.475; 95% CI, 2.442 to 12.279; p < 0.001), and acute rejection (OR, 3.042; 95% CI, 1.241 to 7.454; p = 0.015) were independent risk factors associated with infection. Intra-abdominal infection (n = 35, 20.8%) was the major infectious complication. Among identified bacteria, Enterococcus species (28.4%) were major pathogens, followed by Escherichia coli and Klebsiella species. Conclusions: High preoperative MELD score, deceased-donor type, and acute rejection were risk factors associated with infection. To prevent infections following surgery, it is important to determine the appropriate time of operation before the recipient has a high MELD score. PMID- 29466850 TI - Direct costs of severe cutaneous adverse reactions in a tertiary hospital in Korea. AB - Background/Aims: There are only a few reports on the direct costs of severe cutaneous adverse reactions (SCARs), including drug reaction with eosinophilia and systemic symptoms (DRESS), Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN), despite the tremendous negative impact these reactions can have on patients. We estimated the direct costs of treating SCARs. Methods: Patients admitted to a tertiary teaching hospital for the treatment of SCARs from January 1, 2005 to December 31, 2010 were included. Patients who had experienced SCARs during their admission for other medical conditions were excluded. The direct costs of hospitalization and outpatient department visits were collected. Inpatient and outpatient care costs were calculated, and factors affecting inpatient care costs were analyzed. Results: The total healthcare cost for the management of 73 SCAR patients (36 with DRESS, 21 with SJS, and 16 with TEN) was 752,067 US dollars (USD). Most of the costs were spent on inpatient care (703,832 USD). The median inpatient care cost per person was 3,720 (range, 1,133 to 107,490) USD for DRESS, 4,457 (range, 1,224 to 21,428) USD for SJS, and 8,061 (range, 1,127 to 52,220) USD for TEN. Longer hospitalization significantly increased the inpatient care costs of the patients with DRESS (by 428 USD [range, 395 to 461] per day). Longer hospitalization and death significantly increased the inpatient care costs of the patients with SJS/TEN (179 USD [range, 148 to 210] per day and an additional 14,425 USD [range, 9,513 to 19,337] for the deceased). Conclusions: The management of SCARs required considerable direct medical costs. SCARs are not only a health problem but also a significant financial burden for the affected individuals. PMID- 29466851 TI - Seropositive rate of the anti-hepatitis A immunoglobulin G antibody in maintenance hemodialysis subjects from two hospitals in Korea. AB - Background/Aims: Hepatitis A virus (HAV) is a self-limiting infectious disease, but 1% of subjects develop fulminant hepatitis. The prevalence of the anti-HAV immunoglobulin G (IgG) antibody in hemodialysis subjects in Korea remains unknown. The purpose of this study was to describe and compare the seropositive rate of anti-HAV antibody among hemodialysis subjects in two hospitals according to age group. Methods: A total of 170 hemodialysis subjects were evaluated for the seropositive rate of the anti-HAV IgG antibody and its titer. Results: Of the 170 maintenance hemodialysis subjects in two hospitals (Kangnam 92 vs. Chuncheon 78), 79 (46.5%) were male. The mean age was 53.2 years old, and 94.1% of the subjects were over 40 years old. The median vintage of hemodialysis was 29.0 months. Anti-HAV antibody was found in 163 subjects (95.9%), with no significant difference between the two areas (Kangnam 97.8% [n = 90] vs. Chuncheon 93.6% [n = 73]). Subjects younger than 40 years old showed a seropositive rate of 50%, while the seropositive rate increased with age for subjects aged 40 or older (p for trend < 0.001). Seropositive subjects from Kangnam showed a higher anti-HAV antibody titer than those from Chuncheon (median: Kangnam 14.2 vs. Chuncheon 11.7). Only age influenced seropositivity. The only factor that influenced the antibody level was the location of hospital (p < 0.001). Conclusions: The seropositive rate of the anti-HAV antibody in hemodialysis subjects was 95%, which is similar to findings in the general population. Active immunization against hepatitis A is strongly recommended for hemodialysis subjects under 40 years of age after anti-HAV testing.

PMID- 29466853 TI - Synthesis and Evaluation of a Novel 64Cu- and 67Ga-Labeled Neurokinin 1 Receptor Antagonist for in Vivo Targeting of NK1R-Positive Tumor Xenografts. AB - Neurokinin 1 receptor (NK1R) is expressed in gliomas and neuroendocrine malignancies and represents a promising target for molecular imaging and targeted radionuclide therapy. The goal of this study was to synthesize and evaluate a novel NK1R ligand (NK1R-NOTA) for targeting NK1R-expressing tumors. Using a carboxymethyl moiety linked to L-733060 as a starting reagent, NK1R-NOTA was synthesized in a three-step reaction and then labeled with 64Cu (or 67Ga for in vitro studies) in the presence of CH3COONH4 buffer. The radioligand affinity and cellular uptake were evaluated with NK1R-transduced HEK293 cells (HEK293-NK1R) and NK1R nontransduced HEK293 cells (HEK293-WT) and their xenografts. Radiolabeled NK1R-NOTA was obtained with a radiochemical purity of >95% and specific activities of >7.0 GBq/MUmol for 64Cu and >5.0 GBq/MUmol for 67Ga. Both 64Cu- and 67Ga-labeled NK1R-NOTA demonstrated high levels of uptake in HEK293 NK1R cells, whereas co-incubation with an excess of NK1R ligand L-733060 reduced the level of uptake by 90%. Positron emission tomography (PET) imaging showed that [64Cu]NK1R-NOTA had a accumulated rapidly in HEK293-NK1R xenografts and a 10 fold lower level of uptake in HEK293-WT xenografts. Radioactivity was cleared by gastrointestinal tract and urinary systems. Biodistribution studies confirmed that the tumor-to-organ ratios were >=5 for all studied organs at 1 h p.i., except kidneys, liver, and intestine, and that the tumor-to-intestine and tumor to-kidney ratios were also improved 4 and 20 h post-injection. [64Cu]NK1R-NOTA is a promising ligand for PET imaging of NK1R-expressing tumor xenografts. Delayed imaging with [64Cu]NK1R-NOTA improves image contrast because of the continuous clearance of radioactivity from normal organs. PMID- 29466854 TI - Long Spin-Relaxation Times in a Transition-Metal Atom in Direct Contact to a Metal Substrate. AB - Long spin-relaxation times are a prerequisite for the use of spins in data storage or nanospintronics technologies. An atomic-scale solid-state realization of such a system is the spin of a transition-metal atom adsorbed on a suitable substrate. For the case of a metallic substrate, which enables the direct addressing of the spin by conduction electrons, the experimentally measured lifetimes reported to date are on the order of only hundreds of femtoseconds. Here, we show that the spin states of iron atoms adsorbed directly on a conductive platinum substrate have a surprisingly long spin-relaxation time in the nanosecond regime, which is comparable to that of a transition metal atom decoupled from the substrate electrons by a thin decoupling layer. The combination of long spin-relaxation times and strong coupling to conduction electrons implies the possibility to use flexible coupling schemes to process the spin information. PMID- 29466855 TI - Nano-Assembly of Pamitoyl-Bioconjugated Coenzyme-A for Combinatorial Chemo Biologics in Transcriptional Therapy. AB - Pathogenesis, the biological mechanism that leads to the diseased state, of many cancers is driven by interruptions to the role of Myc oncoprotein, a regulator protein that codes for a transcription factor. One of the most significant biological interruptions to Myc protein is noted as its dimerization with Max protein, another important factor of family of transcription factors. Binding of this heterodimer to E-Boxes, enhancer boxes as DNA response element found in some eukaryotes that act as a protein-binding site and have been found to regulate gene expression, are interrupted to regulate cancer pathogenesis. The systemic effectiveness of potent small molecule inhibitors of Myc-Max dimerization has been limited by poor bioavailability, rapid metabolism, and inadequate target site penetration. The potential of gene therapy for targeting Myc can be fully realized by successful synthesis of a smart cargo. We developed a "nuclein" type nanoparticle "siNozyme" (45 +/- 5 nm) from nanoassembly of pamitoyl-bioconjugated acetyl coenzyme-A for stable incorporation of chemotherapeutics and biologics to achieve remarkable growth inhibition of human melanoma. Results indicated that targeting transcriptional gene cMyc with siRNA with codelivery of a topoisomerase inhibitor, amonafide caused ~90% growth inhibition and 95% protein inhibition. PMID- 29466856 TI - Enhanced Cellular Ablation by Attenuating Hypoxia Status and Reprogramming Tumor Associated Macrophages via NIR Light-Responsive Upconversion Nanocrystals. AB - Near-infrared (NIR) light-mediated photodynamic therapy (PDT), especially based on lanthanide-doped upconversion nanocrystals (UCNs), have been extensively investigated as a promising strategy for effective cellular ablation owing to their unique optical properties to convert NIR light excitation into multiple short-wavelength emissions. Despite the deep tissue penetration of NIR light in living systems, the therapeutic efficiency is greatly restricted by insufficient oxygen supply in hypoxic tumor microenvironment. Moreover, the coexistent tumor associated macrophages (TAMs) play critical roles in tumor recurrence during the post-PDT period. Herein, we developed a unique photosensitizer-loaded UCNs nanoconjugate (PUN) by integrating manganese dioxide (MnO2) nanosheets and hyaluronic acid (HA) biopolymer to improve NIR light-mediated PDT efficacy through attenuating hypoxia status and synergistically reprogramming TAMs populations. After the reaction with overproduced H2O2 in acidic tumor microenvironment, the MnO2 nanosheets were degraded for the production of massive oxygen to greatly enhance the oxygen-dependent PDT efficiency upon 808 nm NIR light irradiation. More importantly, the bioinspired polymer HA could effectively reprogram the polarization of pro-tumor M2-type TAMs to anti-tumor M1-type macrophages to prevent tumor relapse after PDT treatment. Such promising results provided the great opportunities to achieve enhanced cellular ablation upon NIR light-mediated PDT treatment by attenuating hypoxic tumor microenvironment, and thus facilitated the rational design of new generations of nanoplatforms toward immunotherapy to inhibit tumor recurrence during post-PDT period. PMID- 29466857 TI - Sensitive and Selective Fluorescent Probe for Selenol in Living Cells Designed via a p Ka Shift Strategy. AB - Selenocysteine (Sec) is a primary kind of reactive selenium species in cells, and its vital roles in physiological processes have been featured. Thus, the development of highly sensitive and selective methods for the sensing of Sec is of great significance. This work reports a turn-on fluorescent probe for selenol based on the unique fluorescence OFF-ON switching between the Schiff base (SB) and its complementary protonated Schiff base (PSB) form of merocyanine dyes. The probe consists of a merocyanine Schiff base fluorophore and a 2,4 dinitrobenzenesulfonamide moiety that reacts especially with selenol. The fluorescence turn-on response of MC-Sec is realized via the selective removal of the strongly electron withdrawing 2,4-dinitrobenzenesulfonyl group by Sec, leading to a shift in the p Ka of the imine nitrogen of the probe from 6.40 to 9.04 and thus significantly increasing the population of the fluorescent PSB form of the dye at physiological pH. MC-Sec shows good selectivity and sensitivity for Sec and has been applied in the imaging of exogenous and endogenous selenol in living cells by confocal fluorescence microscopy. The proposed mechanism should be useful for developing future probes directed to other target molecules by employing this simple but effective p Ka shift strategy. PMID- 29466858 TI - Release of Terminal Alkynes via Tandem Photodeprotection and Decarboxylation of o Nitrobenzyl Arylpropiolates in a Flow Microchannel Reactor. AB - Photocleavable protecting groups (PPGs) offer a complementary protection paradigm compared to traditional protection groups. Herein, an o-nitrobenzyl (NB) PPG was employed to protect a variety of arylpropiolic acids. Upon a cascade of light triggered photodeprotection in a microchannel reactor (residence times of 100-500 s), followed by Cu-catalyzed decarboxylation at 60 degrees C, the NB-protected arylpropiolic acid afforded a terminal alkyne. This terminal alkyne was further reacted in situ with an azide via click chemistry to yield a 1,2,3-triazole in a one-pot reaction. Furthermore, the effect of different substituents (methyl, vinyl, allyl, and phenyl) at the benzylic position on the rate of photodeprotection was studied. The quantum yields of photolysis for the benzylic substituted esters were determined to be as high as 0.45 compared to the unsubstituted ester with a 0.08 quantum yield of photolysis. PMID- 29466859 TI - Transferable Coarse-Grained Models of Liquid-Liquid Equilibrium Using Local Density Potentials Optimized with the Relative Entropy. AB - Bottom-up coarse-grained (CG) models are now regularly pursued to enable large length and time scale molecular simulations of complex, often macromolecular systems. However, predicting fluid phase equilibria using such models remains fundamentally challenging. A major problem stems from the typically low transferability of CG models beyond the densities and/or compositions at which they are parametrized, which is necessary if they are to describe distinct structural and thermodynamic properties unique to each phase. CG model transferability is compounded by the representation of the inherently multibody coarse interactions using pair potentials that neglect higher order effects. Here, we propose to construct transferable single site CG models of liquid mixtures by supplementing traditional CG pair interactions with local density potentials, which constitute a computationally inexpensive mean-field approach to describe many-body effects, in that site energies are modulated by the local solution environment. To illustrate the approach, we use intra- and interspecies local density potentials to develop CG models of benzene-water solutions that show impressive transferability in structural metrics (pair correlation functions, density profiles) throughout composition space, in contrast to pair only CG representations. While further refinement may be necessary to represent more complex thermodynamic properties, like the liquid-liquid interfacial tension, the generality and improvement offered by the local density approach are highly encouraging for enabling complex phase equilibrium modeling using CG models. PMID- 29466860 TI - Simulations of Pure Ceramide and Ternary Lipid Mixtures as Simple Interior Stratum Corneum Models. AB - The barrier function of the stratum corneum (SC) is intimately related to the structure of the lipid matrix, which is composed of ceramides (Cer), cholesterol (Chol), and free fatty acid (FFA). In this study, the all-atom CHARMM36 (C36) force field is used to simulate bilayers of N-palmitoylsphingosine (Cer16), N lignoceroylsphingosine (Cer24), Chol, and lignoceric acid (LA) as simple models of the SC. Equimolar mixtures of Cer, Chol, and LA are replicated from experiment for comparison and validation of the C36 force field, and the effects of lipid diversity and temperature are studied. The presence of Chol and LA have effects on nearly all membrane properties including surface area per lipid, area compressibility moduli, chain order, Chol tilt, bilayer thickness, interdigitation, hydrogen bonding, and lipid clustering, while temperature has a more moderate effect. In systems containing Cer16, there is a profound difference in interdigitation between pure Cer and mixed systems, while systems containing Cer24 are relatively unaffected. Increasing temperature has the potential to shift hydrogen bonding pairs rather than uniformly decrease bonding, which can lead to greater Cer-Cer bonding at higher temperatures. Comparison with deuterium order parameter experiments demonstrates good agreement, which supports further use of this class of lipids and fatty acids for development of more complex SC models.

AB - Immunorecovery could be attenuated in HIV-hepatitis B virus (HBV) coinfection versus HIV monoinfection during antiretroviral therapy (ART), yet, whether it also occurs in individuals from sub-Saharan Africa without severe comorbidities is unknown. In this study, 808 HIV-infected patients in Cote d'Ivoire initiating continuous ART were included. Six-month CD4+ count trajectories and the proportion reaching CD4+ T cell counts >350/mm3, HIV-RNA <300 copies/mL, still alive and not lost to follow-up within 18 months ("optimal immunorecovery") were compared between coinfected groups. At inclusion, 80 (9.9%) patients were HIV-HBV coinfected, 40 (50.0%) of whom had high HBV-DNA viral load (VL) (>104 copies/mL). Coinfected patients with high HBV-DNA replication initiated ART with significantly lower median CD4+ T cell counts [216/mm3, interquartile range (IQR) = 150-286] compared to coinfection with low HBV-DNA replication (268/mm3, IQR = 178-375) or HIV monoinfection (257/mm3, IQR = 194-329) (p = .003). These patients had significantly faster rates of CD4+ cell count increase from baseline after adjusting for baseline age, World Health Organization stage III/IV, and CD4+ cell counts (p = .04), yet, were not more likely to exhibit optimal immunorecovery (82.5% vs. 80.0% and 77.9%, respectively) (p = .8). In conclusion, change in CD4+ cell counts after ART-initiation was accelerated in coinfected patients with high HBV DNA VLs, but this did not lead to increased rates of optimal immunorecovery. PMID- 29466861 TI - Flexibility-Not just for yoga anymore! AB - Over the past few years, nucleosides have maintained a prominent role as one of the cornerstones of antiviral and anticancer therapeutics, and many approaches to nucleoside drug design have been pursued. One such approach involves flexibility in the sugar moiety of nucleosides, for example, in the highly successful anti HIV and HBV drug tenofovir. In contrast, introduction of flexibility to the nucleobase scaffold has only more recently gained significance with the invention of our fleximers. The history, development, and some biological relevance for this innovative class of nucleosides are detailed herein. PMID- 29466863 TI - OBSERVE-5: Comparison of Etanercept-Treated Psoriasis Patients From Canada and the United States. AB - BACKGROUND: OBSERVE-5 surveillance registry results evaluating etanercept safety and effectiveness in patients with moderate to severe psoriasis from Canada and the United States have been reported from data collected between May 2006 and December 2012. Although both countries have an identical indicated starting dose, the maintenance dose can differ and thus affect management strategies and outcomes. OBJECTIVE: To compare the long-term safety and effectiveness outcomes of etanercept in the Canadian and US cohorts. METHODS: Primary end points included exposure-adjusted event incidence rates of serious adverse events and serious infectious events. Secondary end points included exposure-adjusted event incidence rates of events of medical interest and efficacy outcomes. RESULTS: Over 5 years, Canadian patients received a higher maintenance dose of etanercept (50 mg twice/week) more frequently than those from the United States. Safety outcome comparisons revealed that Canadian patients had a significantly lower occurrence of serious adverse events than patients from the United States, with an overall exposure-adjusted event incidence rate per 100 patient-years of 4.46 (95% confidence interval [CI], 3.05-6.29) vs 7.76 (95% CI 7.04-8.54), respectively. Serious infectious event rates were not significantly different between the 2 countries. Secondary outcomes of events of medical interest and effectiveness also did not reveal significant differences between the 2 cohorts. CONCLUSION: After 5 years of etanercept use, safety and effectiveness outcomes were similar between patients from Canada and the United States, with the exception of a significantly lower rate of serious adverse events in the Canadian population. PMID- 29466864 TI - Quality of Life in a Hospice: A Validation of the Croatian Version of the EORTC QLQ-C15-PAL. AB - PURPOSE: Quality of life is the cornerstone of palliative care, and assessing it requires validated and standardized questionnaires. However, the majority of questionnaires are not tested in a hospice setting. The purpose of this study is to evaluate the quality of life in a hospice using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 15 for Palliative Care (PAL) (EORTC QLQ-C15-PAL) questionnaire and validating it in Croatian language. METHODS: The study was conducted prospectively on 151 consecutive patients who were evaluated at the admittance to the hospice and after 7 days. Along with the EORTC QLQ-C15-PAL, both evaluations included the Edmonton Symptom Assessment System (ESAS) and the Palliative Performance Score (PPS) version 2. Cronbach alpha coefficient was used to test the reliability of multi-item scales, while construct and concurrent validity was tested using the Pearson correlation coefficients. Known-group validity was evaluated using the Student t test. RESULTS: Physical functioning, pain, and emotional functioning scales all exhibited high reliability on both assessments and met the criteria of Cronbach alpha >=.70, while fatigue scale met the predetermined criteria in the follow-up assessment (alpha = .90). Adequate validity was also displayed, with the highest correlation coefficients between the EORTC QLQ-C15-PAL and ESAS scales recorded for the corresponding items. The EORTC QLQ-C15-PAL was also able to distinguish patients with different PPS scores, exhibiting excellent clinical validity. CONCLUSIONS: The EORTC QLQ-C15-PAL can be used successfully in Croatian palliative care. However, inevitable issues such as low retest percentage due to short survival and low physical functioning scores need to be acknowledged in further formulations of quality of life questionnaires specific to hospice care. PMID- 29466865 TI - Regulation of NADPH Oxidases by G Protein-Coupled Receptors. AB - SIGNIFICANCE: G protein-coupled receptors (GPCR) are the largest group of cell surface receptors, which link cells to their environment. Reactive oxygen species (ROS) can act as important cellular signaling molecules. The family of NADPH oxidases generates ROS in response to activated cell surface receptors. Recent Advances: Various signaling pathways linking GPCRs and activation of NADPH oxidases have been characterized. CRITICAL ISSUES: Still, a more detailed analysis of G proteins involved in the GPCR-mediated activation of NADPH oxidases is needed. In addition, a more precise discrimination of NADPH oxidase activation due to either upregulation of subunit expression or post-translational subunit modifications is needed. Also, the role of noncanonical modulators of NADPH oxidase activation in the response to GPCRs awaits further analyses. FUTURE DIRECTIONS: As GPCRs are one of the most popular classes of investigational drug targets, further detailing of G protein-coupled mechanisms in the activation mechanism of NADPH oxidases as well as better understanding of the link between newly identified NADPH oxidase interaction partners and GPCR signaling will provide new opportunities for improved efficiency and decreased off target effects of therapies targeting GPCRs.

AB - OBJECTIVES: Alcohol misuse and depression are commonly co-occurring conditions. To date, no review has examined the most efficacious treatment model for psychosocial treatment of co-occurring alcohol misuse and depression. This systematic review determined the: (i) methodological quality of publications examining psychosocial treatment of co-occurring alcohol misuse and depression using a sequential, parallel or integrated treatment model; and (ii) effectiveness of each dual treatment model compared to single treatment for those with co-occurring alcohol misuse and depression. METHODS: PubMed, Medline and PsycInfo databases were searched for studies which were included if they involved treatment for alcohol misuse and depression and could be classified into one of the three treatment models. Included studies were assessed using the Cochrane's Effective Practice and Organisation of Care risk of bias criteria. Relevant study characteristics and outcomes were extracted and are presented in a narrative review format. RESULTS: Seven studies met inclusion criteria. None were categorised as low risk on the risk of bias criteria. No studies examined a sequential model of treatment, three examined a parallel model and four examined an integrated model of dual-focussed treatment. The studies examining the parallel model and two out of four studies examining the effectiveness of an integrated model demonstrated greater improvement for alcohol or depression outcomes compared to control conditions. CONCLUSION: Evidence for the psychosocial treatment of co-occurring alcohol misuse and depression is limited to a handful of studies. The evidence has several methodological limitations, which impact the interpretation of the findings. Therefore, while international guidelines recommend integrated dual-focussed treatment for co-occurring conditions, there is little evidence supporting the superiority of this treatment format for co-occurring alcohol misuse and depression. High-quality research demonstrating improvements in patient outcomes is required to ensure recommendations for clinical practice are based on strong empirical evidence. PMID- 29466869 TI - Patient-specific CT-based 3D passive FSI model for left ventricle in hypertrophic obstructive cardiomyopathy. AB - Left ventricular outflow tract obstruction is observed in 70% of patients with hypertrophic cardiomyopathy, which occurs in about 1 of every 500 adults in the general population. It has been widely believed that the motion of the mitral valve, in particular, its systolic anterior motion (SAM), attributes significantly to such obstruction. For a better understanding of the mitral valve motion, a 3D patient-specific fluid-structure interaction model of the left ventricle from a patient with hypertrophic obstructive cardiomyopathy based on computed tomography (CT) scan images was proposed in this study. Displacement, structural stress, pressure, flow velocity and shear stress within the left ventricle and mitral valve were extracted to characterize their behavior. The maximum shear stress on mitral valve was 9.68 [Formula: see text]. The pressure on its posterior leaflet was higher than that on the anterior leaflet and the peak pressure on the mitral valve was 93.5 mm Hg which occurred at pre-SAM time. High angles of attack (54.3 +/- 22.4 degrees ) were found in this patient. The methodology established in this study may have the potential to clarify the mechanisms of SAM and ultimately optimize surgical planning by comparing the mechanical results obtained from preoperative and postoperative models.

AB - OBJECTIVES: To determine the accuracy of the surgeon's impression as to the stone free rate at the end of percutaneous nephrolithotomy (PCNL), and to evaluate predictors for inaccurate estimation. MATERIALS AND METHODS: A prospective study conducted between 2010 and 2015. Surgeon's impression, categorized as "insignificant residual fragments (RFs)" (<4 mm) or "significant RF" (>4 mm), was recorded at the end of PCNL, and was compared with postoperative imaging results, using CT or a combination of US and kidney, ureter, and bladder radiograph for radiolucent and radio-opaque stones, respectively. The association between missed significant RF and the patient and operative variables was evaluated with univariable and multivariable logistic regression analysis. RESULTS: The study cohort included 312 patients. Significant RFs were found in 75 (24%) patients, comprising all 22 patients in whom RFs were suspected (100%) and 53 patients who were considered stone free (18.6%). The sensitivity, specificity, and positive and negative predictive value of the surgeon's estimation for the absence of significant RFs were 100%, 39%, 0.83, and 1 for radiopaque stones, and 100%, 12.5%, 0.75, and 1 for radiolucent stones. On multivariate analysis, multiple stones (OR = 4, 95% CI: 1.85-8.7, p < 0.001) and cumulative stone size (OR = 1.04, 95% CI: 1.02-1.1, p = 0.005) were independent predictors for missed RFs. CONCLUSION: In approximately fifth of the patients undergoing PCNL, the surgeon's impression of "insignificant RF" may be inaccurate. Stone size and number were independently associated with higher miss rate. These data should be shared with the patients when the postoperative drainage method and the option for an auxiliary procedure are discussed. PMID- 29466871 TI - Design of a Novel Gene Therapy Construct to Achieve Sustained Brain-Derived Neurotrophic Factor Signaling in Neurons. AB - Brain-derived neurotrophic factor (BDNF) acting through the tropomyosin-related receptor-B (TrkB) is an important signaling system for the maintenance and survival of neurons. Gene therapy using either recombinant adeno-associated virus (AAV) or lentiviral vectors can provide sustained delivery of BDNF to tissues where reduced BDNF signaling is hypothesized to contribute to disease pathophysiology. However, elevation in BDNF at target sites has been shown to lead to a downregulation of TrkB receptors, thereby reducing the effect of chronic BDNF delivery over time. A novel gene sequence has been designed coding both the ligand (BDNF) and the TrkB receptor in a single transgene separated by a short viral-2A sequence. The single transgene is efficiently processed intracellularly in vitro and in vivo to yield the two mature proteins, which are then independently transported to their final cellular locations: TrkB receptors to the cell surface, and BDNF contained within secretory vesicles. To accommodate the coding sequences of both BDNF and TrkB receptors within the narrow confines of the AAV vectors (4.7 kb pairs), the coding region for the pro-domain of BDNF was removed and the signal peptide sequence modified to improve production, intracellular transport, and secretion of mature BDNF (mBDNF). Intracellular processing and efficacy was shown in HEK293 cells and SH-SY5Y neuroblastoma cells using plasmid DNA and after incorporating the TrkB-2A-mBDNF into an AAV2 vector. Increased BDNF/TrkB-mediated intracellular signaling pathways were observed after AAV2 vector transfection while increased TrkB phosphorylation could be detected in combination with neuroprotection from hydrogen peroxide-induced oxidative stress. Correct processing was also shown in vivo in mouse retinal ganglion cells after AAV2 vector administration to the eye. This novel construct is currently being investigated for its efficacy in animal models to determine its potential to progress to human clinical studies in the future. PMID- 29466872 TI - Attenuation of EGFL7 Expression Inhibits Growth Hormone-Producing Pituitary Adenomas Growth and Invasion. AB - Invasiveness of growth hormone-producing pituitary adenomas (GHPAs) causes difficulties in safe and complete adenoma removal during surgery and often leads to high recurrence. Epidermal growth factor-like domain 7 (EGFL7) has been shown to be able to promote tumor angiogenesis, growth, invasiveness, and metastasis through the Notch signaling pathway. It was previously demonstrated that EGFL7 was overexpressed in GHPAs. This study reports that EGFL7 and Notch2 (positive correlation with EGFL7) are overexpressed in invasive GHPA. A long-rank test (Kaplan-Meier method) shows that invasive GHPAs with EGFL7 strong expression results in reduced recurrence-free survival. Multivariate Cox regression analysis reveals that weak EGFL7 expression is an independent prognostic factor for recurrence-free survival. In addition, knockdown of EGFL7 expression suppresses proliferation and invasion of GH3 and GT1-1 cells in vitro. Moreover, attenuation of EGFL7 inhibits human GHPA growth in vivo. The data suggest that as a Notch agonist, EGFL7 may potentially be an appropriate novel molecular target for future development of GHPA medical therapy. PMID- 29466873 TI - The relationship between Pittsburgh Sleep Quality Index subscales and diabetes control. AB - Objectives Data suggest that poor sleep quality as measured by the Pittsburgh Sleep Quality Index (PSQI) contributes to suboptimal diabetes control. How the subscales comprising the PSQI individually relate to diabetes control is poorly understood. Methods In order to explore how PSQI subscales relate to diabetes control, we analyzed baseline data from a trial of a telemedicine intervention for diabetes. We used multivariable modeling to examine: (1) the relationship between the global PSQI and hemoglobin A1c (HbA1c); (2) the relationships between the 7 PSQI subscales and HbA1c; and (3) medication nonadherence as a possible mediating factor. Results Global PSQI was not associated with HbA1c ( n = 279). Only one PSQI subscale, sleep disturbances, was associated with HbA1c after covariate adjustment; HbA1c increased by 0.4 points for each additional sleep disturbances subscale point (95%CI 0.1 to 0.8). Although the sleep disturbances subscale was associated with medication nonadherence (OR 2.04, 95%CI 1.27 to 3.30), a mediation analysis indicated nonadherence does not mediate the sleep disturbances-HbA1c relationship. Discussion The sleep disturbances subscale may drive the previously observed relationship between PSQI and HbA1c. The mechanism for the relationship between sleep disturbances and HbA1c remains unclear, as does the impact on HbA1c of addressing sleep disturbances. PMID- 29466874 TI - Patient expertise: Contested territory in the realm of long-term condition care. AB - Objectives The aim of this study was to describe the experience of people with multiple long-term conditions with particular reference to the notion of the 'expert patient' in the context of self-management. Methods A multiple case study of 16 people with several long-term conditions, included interviews and contacts over an 18-month period and an interview with their primary care clinicians. Analysis included both case-by-case and some cross-case analysis. Results The findings reveal the patient participants had little capacity to exercise the agency necessary be an expert patient as premised. Weariness, shame, expertise, issues of compliance and control and collaboration are contested areas underpinning clinician encounters. Discussion Patient expertise is at the heart of self-management approaches but the findings surfaced several inherent contradictions between the idealised expert patient and their position within a health care system that is entrenched in biomedicine. Conclusion There is a mismatch between how the self-management approach has been operationalised and what the participants who have multiple LTCs reveal as what they want and need. The research concludes that the self-management approach is inappropriate for people with multiple LTCs and that other ways of offering care should be considered. PMID- 29466876 TI - SREBP2 contributes to cisplatin resistance in ovarian cancer cells. AB - This study is to investigate transcription factors involved in cisplatin resistance in ovarian cancer cells. The transcriptome of cisplatin resistant and sensitive A2780 epithelial ovarian cancer cells was obtained from GSE15372. Ovarian transcriptome data GSE62944 was downloaded from TCGA and applied for transcription regulatory network analysis. The analysis results were confirmed using quantitative polymerase chain reaction. The roles of SREBP2 in cisplatin resistant cells were investigated by RNA inference and cell viability analysis. Transcription regulatory network analysis found that 12 transcription factors and their targets were involved in cisplatin resistant in A2780 cells. Among these factors, the targets of EZH2 and SREBP2 revealed by Transcriptional Regulatory Relationships Unraveled by Sentence-based Text mining were also enriched in differentially expressed genes between cisplatin resistant and cisplatin sensitive cells. Their targets were enriched mainly in cell cycle and cholesterol metabolic process, respectively. Bioinformatic analysis illustrated three known targets of SREBP2, namely LDLR, FDFT1, and HMGCR were increased in A2780 resistant cell lines. Additionally, the three genes and SREBP2 were also elevated in live cells after cisplatin treatment via quantitative polymerase chain reaction. Importantly, RNA inference of SREBP2 in A2780 cell line resulted in a decrease of cell viability after cisplatin treatment. SREBP2 played important roles in cisplatin resistance and cholesterol metabolic process might be a novel target for cancer therapy. Impact statement Transcriptome of cisplatin resistant and sensitive A2780 epithelial ovarian cancer cells was obtained from GSE15372 and TCGA. Twelve transcription factors and their targets were involved in cisplatin resistant. Among these factors, the targets of EZH2 and SREBP2 revealed by Transcriptional Regulatory Relationships Unraveled by Sentence-based Text mining were also enriched in differentially expressed genes. Their targets were enriched mainly in cell cycle and cholesterol metabolic process. Three targets of SREBP2, namely LDLR, FDFT1, and HMGCR were increased in A2780-resistant cell lines and were found elevated in live cells after cisplatin treatment via qPCR. RNAi of SREBP2 in A2780 cell line resulted in a decrease of cell viability after cisplatin treatment. SREBP2 played important roles in cisplatin resistance and might be a novel target for cancer therapy. PMID- 29466875 TI - Impacts of maternal dietary protein intake on fetal survival, growth, and development. AB - Maternal nutrition during gestation, especially dietary protein intake, is a key determinant in embryonic survival, growth, and development. Low maternal dietary protein intake can cause embryonic losses, intra-uterine growth restriction, and reduced postnatal growth due to a deficiency in specific amino acids that are important for cell metabolism and function. Of note, high maternal dietary protein intake can also result in intra-uterine growth restriction and embryonic death, due to amino acid excesses, as well as the toxicity of ammonia, homocysteine, and H2S that are generated from amino acid catabolism. Maternal protein nutrition has a pronounced impact on fetal programming and alters the expression of genes in the fetal genome. As a precursor to the synthesis of molecules (e.g. nitric oxide, polyamines, and creatine) with cell signaling and metabolic functions, L-arginine (Arg) is essential during pregnancy for growth and development of the conceptus. With inadequate maternal dietary protein intake, Arg and other important amino acids are deficient in mother and fetus. Dietary supplementation of Arg during gestation has been effective in improving embryonic survival and development of the conceptus in many species, including humans, pigs, sheep, mice, and rats. Both the balance among amino acids and their quantity are critical for healthy pregnancies and offspring. Impact statement This review aims at: highlighting adverse effects of elevated levels of ammonia in mother or fetus on embryonic/fetal survival, growth, and development; helping nutritionists and practitioners to understand the mechanisms whereby elevated levels of ammonia in mother or fetus results in embryonic/fetal death, growth restriction, and developmental abnormalities; and bringing, into the attention of nutritionists and practitioners, the problems of excess or inadequate dietary intake of protein or amino acids on pregnancy outcomes in animals and humans. The article provides new, effective means to improve embryonic/fetal survival and growth in mammals. PMID- 29466877 TI - Behavior and health beliefs as predictors of HIV testing among women: a prospective study of observed HIV testing. AB - : Much of the research examining predictors of HIV testing has used retrospective self-report to assess HIV testing. FINDINGS: therefore, may be subject to recall bias and to difficulties determining the direction of associations. In this prospective study, we administered surveys to women in community clinics to identify predictors of subsequent observed HIV testing, overcoming these limitations. Eighty-three percent were tested. In the adjusted multivariable model, being born in the U.S., perceived benefits of testing, worries about being infected with HIV, having had more than 15 lifetime sexual partners, and having had one or more casual sexual partners in the previous three months predicted acceptance of testing. Perceived obstacles to testing predicted non-acceptance. Those who had never been tested for HIV and those tested two to five years previously had greater odds of test acceptance than those who had been tested within the last year. The findings from this study with observed testing as the outcome, confirm some of the results from retrospective, self-report studies. Participants made largely rational decisions about testing, reflecting assessments of their risk and their history of HIV testing. Health beliefs are potentially modifiable through behavioral intervention, and such interventions might result in greater acceptance of testing.

PMID- 29466878 TI - Automated Computer Software Compared with Manual Measurements for CT-Based Urinary Stone Metrics: An Evaluation Study. AB - INTRODUCTION AND OBJECTIVE: Stone size guides treatment decisions, yet there is no standard method for measuring stone size. Prior work has shown significant variability in manual stone measurements. We tested a novel stone software program designed to provide an automated and objective comprehensive CT-based stone profile. METHODS: Urinary stones identified on CT imaging were manually measured to obtain linear size and maximal stone density (in Hounsfield unit [HU]). Manual stone volume was calculated using the formula 0.52 * length * width * height. The same stones were assessed with computer software capable of automatically providing stone length, density, and volume. Computer measurements were compared with manual measurements. RESULTS: Eighty-five stones were identified on 42 CT scans from 17 patients. Manual measurements showed an average length of 8 mm (range 1.9-21 mm), average maximal density of 686 HU (126-1492 HU), and average stone volume of 192 mm3 (2.9-2555 mm3). Automated computer measurements did not differ from manual measurements for density (755 HU vs 686 HU, p = 0.18) and volume (183 mm3 vs 192 mm3, p = 0.86. Automated length was slightly longer then manual length (10 mm vs 8 mm, p < 0.003). The mean percent differences between manual and automated metrics were 14.3% for density, 21.0% for volume, and 25.2% for length. CONCLUSION: Automated stone measurements can be accomplished quickly and precisely with dedicated software that can assess stones of varying size as well as stones with complex geometry. This software eliminates interobserver variability and offers a comprehensive stone profile with which to make clinical decisions. PMID- 29466879 TI - Pituitary adenylate cyclase-activating polypeptide ameliorates vascular dysfunction induced by hyperglycaemia. AB - BACKGROUND: Short-lasting hyperglycaemia occurs frequently in prediabetes and poorly controlled diabetes mellitus leading to vascular damage. Pituitary adenylate cyclase-activating polypeptide (PACAP) has been shown to play a protective role in vascular complications of diabetes; moreover, antioxidant effects of PACAP were also described. Therefore, we hypothesized that PACAP exerts protective effects in short-term hyperglycaemia-induced vascular dysfunctions. METHODS: After short-term hyperglycaemia, acetylcholine-induced and sodium nitroprusside-induced vascular relaxation of mouse carotid arteries were tested with a myograph with or without the presence of PACAP or superoxide dismutase. Potential direct antioxidant superoxide-scavenging action of pituitary adenylate cyclase-activating peptide was tested with pyrogallol autoxidation assay; furthermore, the effect of pituitary adenylate cyclase-activating peptide or superoxide dismutase was investigated on hyperglycaemia-associated vascular markers. RESULTS: PACAP administration resulted in reduced endothelial dysfunction after a 1-h hyperglycaemic episode. PACAP was able to restore acetylcholine-induced relaxation of the vessels and improved sodium nitroprusside induced relaxation. This effect was comparable to the protective effect of superoxide dismutase, but PACAP was unable to directly scavenge superoxide produced by autoxidation of pyrogallol. Endothelial dysfunction was associated with elevated levels of fibroblast growth factor basic, matrix metalloproteinase 9 and nephroblastoma overexpressed gene proteins. Their release was reduced by PACAP administration. CONCLUSION: These results suggest a strong protective role of PACAP in the vascular complications of diabetes. PMID- 29466881 TI - A Comparison of Responses to Substantive Transition Prompts in Interviews With Children. AB - This study examined children's responses to two alternate prompts used to transition to the substantive phase of an interview. Children ( N = 401) experienced four scripted events and were later interviewed. After rapport building, half of the children were asked, "Tell me what you're here to talk to me about today," whereas the other half were asked, "Tell me why you're here to talk to me today." Children's responses were coded as informative (e.g., nouns) or uninformative (e.g., "don't know"). The what prompt elicited more informative responses than the why prompt, and 7- to 9-year-olds were more informative than 5 to 6-year-olds regardless of the type of prompt they received. Given that the what prompt elicited more informative responses, the present study provides initial support for this phrasing when forensic interviewers transition to the substantive phase. PMID- 29466880 TI - Telmisartan reverses antiretroviral-induced adipocyte toxicity and insulin resistance in vitro. AB - BACKGROUND: Antiretroviral therapy in HIV-positive patients leads to insulin resistance which is central to the pathogenesis of various metabolic abnormalities and cardiovascular disease seen in this patient group. We have investigated the dose-response relationship of telmisartan, an antihypertensive, on adipocytes in vitro in order to determine whether it may have metabolic beneficial effects. METHODS: Using in vitro chronic toxicity models (3T3-F442A murine and primary human adipocytes), we evaluated the effects of different concentrations of telmisartan on adipocyte differentiation and adipogenic gene expression using lipid accumulation assays and real-time polymerase chain reaction, respectively. Adipokine secretion and expression of insulin signalling mediators were evaluated using enzyme-linked immunosorbent assays. RESULTS: Telmisartan partially reversed the deleterious effects of antiretrovirals on adipocyte lipid accumulation, expression of adipogenic regulators (peroxisome proliferator receptor-gamma and lipin 1), adipokine secretion and expression of the insulin signalling mediator pAktSer473. The metabolic effects of telmisartan followed a non-monotonic response with the maximal effect observed at 5 uM in the primary human adipocyte model. CONCLUSION: Telmisartan has beneficial metabolic effects in adipocytes in vitro, but its potential to reduce antiretroviral induced cardiometabolic disease in HIV-infected individuals needs to be evaluated in a well-designed adequately powered clinical trial. PMID- 29466882 TI - Emulsifying conditions and processing parameters optimisation of kenaf seed oil in-water nanoemulsions stabilised by ternary emulsifier mixtures. AB - Kenaf ( Hibiscus cannabinus L.) seed oil has been proven for its multi pharmacological benefits; however, its poor water solubility and stability have limited its industrial applications. This study was aimed to further improve the stability of pre-developed kenaf seed oil-in-water nanoemulsions by using food grade ternary emulsifiers. The effects of emulsifier concentration (1, 5, 10, 15% w/w), homogenisation pressure (16,000, 22,000, 28,000 psi), and homogenisation cycles (three, four, five cycles) were studied to produce high stability of kenaf seed oil-in-water nanoemulsions using high pressure homogeniser. Generally, results showed that the emulsifier concentration and homogenisation conditions had great effect ( p < 0.05) on the particle sizes, polydispersity index and hence the physical stability of nanoemulsions. Homogenisation parameters at 28,000 psi for three cycles produced the most stable homogeneous nanoemulsions that were below 130 nm, below 0.16, and above -40 mV of particle size, polydispersity index, and zeta potential, respectively. Field emission scanning electron microscopy micrograph showed that the optimised nanoemulsions had a good distribution within nano-range. The optimised nanoemulsions were proved to be physically stable for up to six weeks of storage at room temperature. The results from this study also provided valuable information in producing stable kenaf seed oil nanoemulsions for the future application in food and nutraceutical industries.

AB - INTRODUCTION: The emergence of novel intralesional therapies have dramatically changed the treatment landscape for melanoma. The heterogeneous presentation of melanoma continues to pose challenges for clinicians, especially when dealing with advanced locoregional disease. Intralesional therapies have the benefit of causing local tumor destruction, while minimizing systemic toxicity. Moreover, the integration of immunotherapeutic agents into intralesional compounds has resulted in the additional benefit of a bystander effect, whereby untreated distant lesions also derive a benefit from treatment. Intralesional therapy has assumed an important role in the management of unresectable, locoregional disease for melanoma. Areas covered: Multiple intralesional agents have been studied over the years, with only a few demonstrating promising results. This review will provide an overview of the different intralesional agents for melanoma. Mechanisms of action, clinical efficacy, and side effects will be the primary focus. Expert commentary: Treatment options for advanced melanoma continue to evolve. Attractive new therapies delivered by an intralesional route has demonstrated promising results, with minimal side effects. The ideal treatment strategy for melanoma will remain a multimodal approach; intralesional therapy provides an additional tool in the treatment armamentarium for melanoma.

AB - INTRODUCTION: Major depressive disorder (MDD) and bipolar disorder (BD) are leading causes of disability worldwide, yet many people remain undiagnosed, are misdiagnosed, and/or ineffectively treated. Diagnosis relies on the clinical assessment of symptoms, and there is currently no molecular or brain-imaging diagnostic test available. Identifying and validating protein biomarkers could provide a more accurate and objective means of diagnosis. Areas covered: Proteomics is a powerful tool that enables the identification and quantification of novel candidate biomarkers of disease. In this review, we discuss the role of proteomic technologies in biomarker discovery and validation, peripheral blood as a source of protein biomarkers, statistical methods for analyzing proteomic data, and some existing challenges in the field. We also review a selection of previously published studies focused on identifying blood-based diagnostic protein biomarkers of MDD and BD within a ten-year period. Expert commentary: Proteomic studies have led to the identification of numerous potential biomarkers of MDD and BD. However, clinical validation and translation into clinical practice have not yet been achieved. Conducting large-scale validation studies and addressing various factors that limit the reproducibility of the proteomic findings are key to ensure that robust and reliable biomarker tests are developed and clinically validated. PMID- 29466887 TI - Access to anti-cancer drugs in India: is there a need to revise reimbursement policies? AB - BACKGROUND: The aim of this study was to examine the access of Indian cancer patients to optimum cancer care under selected government schemes by reviewing reimbursement schemes for cancer care in India. METHODS: All cancer care reimbursement schemes in India were identified and three highly utilized schemes (VAS, RAS, CMCHS) were selected. Quality of breast, colorectal, lung, head & neck, and gastric cancer care was reviewed with respect to NCCN guidelines. Direct medical costs and shortage of budget in reimbursed amounts were calculated for each listed chemotherapy regimen. RESULTS: Medical oncology practice following the schemes' formularies is inferior to recommendations by the NCCN guidelines. Innovative treatment (targeted therapies) like trastuzumab, pertuzumab (breast), bevacizumab, cetuximab, panitumumab (colorectal), erlotinib, gefitinib, crizotinib, and nivolumab (lung) are either not reimbursed (VAS, CMCHS) or partially reimbursed (RAS). Average shortage of budget was found to be 43% (breast), 55% (colorectal), 74% (lung), 7% (head & neck), and 51% (gastric cancer). CONCLUSIONS: Policy makers should consider addition of newer treatments, exclusion of sub-optimal treatments, increments in per patient budget and optimization of supportive care, which may contribute to improvements in survival and quality of life for Indian cancer patients.

PMID- 29466889 TI - Downregulated N-acetylglucosaminyltransferase III is involved in attenuating trophoblast migration and invasion under hypoxia-reoxygenation condition. AB - OBJECTIVE: Many studies have confirmed that N-acetylglucosaminyltransferase III (GnT-III) is correlated with tumor invasion and metastasis. However, the expression of GnT-III and its role in normal pregnancy and preeclampsia (PE) has not been reached. So the primary objective of this study is to determine GnT-III expression in normal pregnancy and whether its expression is vulnerable to oxidative stress in the trophoblast cells. METHODS: Human first trimester villous tissues from normal pregnancies and third trimester placentas from pregnancies with or without preeclampsia (PE) were used for the detection of GnT-III expression. Human first trimester extravillous trophoblast cell line (HTR8/SVneo) exposed to hypoxia/reoxygenation (H/R) condition was employed as an oxidative stress model in vitro to investigate the expression of GnT-III. RESULTS: GnT-III was strongly expressed in cytotrophoblast (CTBs), syncytiotrophoblast (STBs) and the trophoblast columns (TCs) of human placental villi, and decidual cells in the maternal decidua. The expression of GnT-III was decreased in PE placentas compared with the normal control placentas. In addition, GnT-III was found to have decreased expression in H/R-exposed HTR8/SVneo cells, and the invasive and migratory abilities of HTR8/SVneo cells were attenuated, too. CONCLUSIONS: These findings suggest that GnT-III is an important regulator at the maternal-fetal interface during early pregnancy. Excessive oxidative stress can decrease GnT-III expression in trophoblast and the decreased expression of GnT-III may be involved in the development of preeclampsia.

AB - INTRODUCTION: The development of therapeutics for central nervous system (CNS) disorders is still considered a challenging area in drug development due to insufficient translocation through the blood-brain barrier (BBB). Under normal conditions, BBB restrict the penetration of more than 98% of blood-borne molecules including drugs to the CNS. However, recent research findings have proven that the nature of the BBB is altered in several neurological conditions. This complexity encourages revisiting drug delivery strategies to the CNS as this can give a wide range of opportunities for CNS drug development. Areas covered: This review focuses on nanotechnology-based drug delivery platforms designed for selective recruitment into the lesioned brain by taking advantages of BBB disruption that is associated with certain neurological conditions. Expert opinion: Current CNS therapeutic strategies do not fully address the pathophysiological adaptation of BBB in their design. The lack of selective delivery to the brain lesions has been the culprit behind the failure of many CNS therapeutics. This highlighted the need for smart designs of advanced drug delivery systems that take advantage of BBB structural changes in CNS diseases. Recently, promising examples have been reported in this area, however, more work is still required beyond the preclinical testing. PMID- 29466891 TI - Proenkephalin and risk of developing chronic kidney disease: the Prevention of Renal and Vascular End-stage Disease study. AB - BACKGROUND: Proenkephalin (pro-ENK) was recently found to be associated with low estimated glomerular filtration rate (eGFR). The association of pro-ENK with urinary albumin excretion (UAE), another marker for chronic kidney disease (CKD), has not been investigated. We examined the association of pro-ENK with eGFR and UAE as markers of CKD. METHODS: We included 4375 subjects of the Prevention of Renal and Vascular End-Stage Disease (PREVEND) study. CKDeGFR was defined as development of eGFR <60 ml/min/1.73 m2 and CKDUAE as albuminuria >30 mg/24 h. RESULTS: Baseline median pro-ENK was 52.2 (IQR: 44.9-60.5) pmol/L. After a median follow-up of 8.4 (IQR: 7.9-8.9) years, 183 subjects developed CKDeGFR and 371 developed CKDUAE. The association of pro-ENK with CKDeGFR was modified by sex (Pinteraction < 0.1), in such a way that after adjustment, the association only remained significant in men (adjusted hazard ratio per SD increase in 10log transformed pro-ENK, 1.65; 95% CI: 1.15-2.36) and not in women (0.83; 0.58-1.20). No significant association was observed between pro-ENK and CKDUAE risk (0.83; 0.58-1.20). CONCLUSIONS: High pro-ENK is associated with increased risk of CKDeGFR in men, but not in women. No association of pro-ENK with CKDUAE was observed. These results should be interpreted with caution, since residual confounding and potential overfitting of models could have influenced the results. PMID- 29466892 TI - Can etanercept treatment failure in moderate-to-severe psoriasis be overcome by addition of low-dose methotrexate? A single-center experience. AB - BACKGROUND: Loss of efficacy is a major anticipated shortcoming of utilizing etanercept and other biologic agents for treating moderate-to-severe psoriasis. PURPOSE: To investigate the addition of low-dose methotrexate as a means to increase etanercept drug survival. METHODS: Eleven patients with severe psoriasis were switched to a combination of etanercept with low-dose methotrexate therapy, after a primary or secondary failure with etanercept treatment as a monotherapy. Time period for cessation of combined treatment and side effects were documented. The effect of previous methotrexate treatment was investigated. RESULTS: Six men and five women were included in the study. The patients had moderate-to-severe psoriasis with a mean baseline Psoriasis Area and Severity Index (PASI) of 29 (median 25). Median duration of etanercept monotherapy was 12 months. Median duration of combined treatment was 13 months. Combined treatment was discontinued in three patients due to side effects. Previous failure of methotrexate monotherapy did not alter the duration of the combined treatment. CONCLUSION: Addition of low-dose methotrexate may rescue etanercept therapy after failure of etanercept monotherapy in patients with moderate-to-severe psoriasis. PMID- 29466893 TI - Physical Function in U.S. Older Adults Compared With Other Populations: A Multinational Study. AB - OBJECTIVE: We compare physical performance from three U.S. national surveys and nationally representative surveys in England, Taiwan, and Costa Rica. METHOD: For each performance test, we use local mean smoothing to plot the age profiles by sex and survey wave and then fit a linear regression model to the pooled data, separately by sex, to test for significant differences across surveys controlling for age and height. RESULTS: Age profiles of performance vary across U.S. surveys, but levels of lung function (peak expiratory flow) and handgrip strength in the United States are as high as they are in the other three countries. Americans also perform as well on the chair stand test as the English and Costa Ricans, if not better, but exhibit slower gait speed than the English at most ages. DISCUSSION: With the exception of walking speed, we find little evidence that older Americans have worse physical performance than their peers. PMID- 29466894 TI - A preliminary study on topical ozonated oil in the therapeutic management of atopic dermatitis in murine. AB - OBJECTIVE: To explore whether ozonated oil recovery atopic dermatitis (AD) via immunoregulation. METHODS: Mice were repeatedly challenged with the triplex allergens of staphylococcal enterotoxin B, ovalbumin and calcipotriol ointment on the back to develop AD lesions, and were treated with ozonated oil. The lesional skins were scanned by reflectance confocal microscopy to measure the thickness of epidermis. The skin tissues were stained. Th1-type and Th2-type cytokines in serum and in tissues were detected by ELISA and real-time PCR, respectively. RESULTS: Ozonated oil significantly inhibited inflammation and healed the lesions in 7 d. Ozonated oil inhibited NGF expression as compared to the groups treated with vehicle or PBS (p < .01).The serum proteins and lesional transcripts of Th2 cytokines including IL-4 and IL-31 were lower in the ozonated oil treated group than the groups treated with vehicle or PBS (p < .05). The IL-10 level was increased with treatment of ozonated oil (p < .01). On the other hand, the expressions of Th1 cytokines including IL-2, TNF-alpha, and IFN-gamma in the serum were not regulated by ozonated oil. CONCLUSIONS: Our results showed that ozonated oil could suppress inflammation in an AD murine via decreasing Th2 dominant cytokines response and increasing IL-10 expression. These suggest that ozonated oil may be a potential remedy for AD. PMID- 29466895 TI - Altered plasma-type gelsolin and amyloid-beta in neonates with hypoxic-ischaemic encephalopathy under therapeutic hypothermia. AB - Hypoxic-ischemic encephalopathy (HIE) is a severe neonatal complication responsible for ~23% of all neonatal deaths. Also, 30-70% of these patients will suffer lifetime disabilities, including learning impairment, epilepsy or cerebral palsy. However, biomarkers for HIE screening, or monitoring disease progression are limited. Herein, we sought to evaluate the clinical usefulness of plasma-type gelsolin (pGSN) and amyloid-beta (Abeta) 40 and 42 as prognostic biomarkers for HIE. pGSN has been previously suggested as a feasible marker in other brain injuries and amyloid-beta 40 and 42 are classically assessed in neurodegenerative diseases. However, to our knowledge, they have not been previously assessed in HIE patients. We have analyzed plasma pGSN and Abeta 40 and 42 levels in 55 newborns (16 controls, 16 mild and 23 moderate-severe HIE) at birth, during 72 h of therapeutic hypothermia, a gold-standard treatment for HIE, and 24 h after hypothermia. Abeta levels were lower in HIE patients, and pGSN levels were progressively reduced in mild and moderate-severe HIE patients. The fact that pGSN reductions could predict the severity of HIE and significantly correlated with the time to undergo hypothermia supports the prognostic value of plasmatic pGSN. Further studies are warranted to investigate the role of pGSN in neonatal HIE. PMID- 29466896 TI - Reentry Devices for Lamella Neofenestration During Endovascular Aortic Repair of Chronic Type B Aortic Dissection. AB - PURPOSE: To present a technique that creates a neofenestration in the dissecting lamella of chronic aortic dissections using standard or intravenous ultrasound (IVUS)-guided reentry devices. TECHNIQUE: To create a neofenestration, a standard or IVUS-guided reentry device is deployed in either the true or false aortic lumen while a balloon is simultaneously inflated in the opposite lumen to stabilize the lamella, provide needle counterforce, and prevent displacement of the lamella away from the reentry needle. Once the lamella is perforated and a guidewire passed across the 2 lumens, progressive dilation of the neofenestration is performed to establish persistent communication. CONCLUSION: The balloon supported lamella neofenestration technique involving off-label application of two currently available reentry devices can be applied to endovascular treatment chronic aortic dissections. While the technique will definitely not become a standard of practice, it provides a safe, effective, and readily available option for endovascular management of those patients with complex chronic aortic dissections requiring bailout maneuvers or elective treatment. PMID- 29466897 TI - Patients Older Than 80 Years Can Reach Their Normal Life Expectancy After Abdominal Aortic Aneurysm Repair: A Comparison Between Endovascular Aneurysm Repair and Open Surgery. AB - PURPOSE: To investigate the long-term outcomes of endovascular aneurysm repair (EVAR) and open surgical repair (OSR) of infrarenal abdominal aortic aneurysm in octogenarian patients and to compare them with the overall expected survival based on a sex- and age-matched German population. METHODS: A total of 177 patients (median age 82 years; 149 men) >=80 years old (range 80-92) who underwent primary elective repair of an infrarenal aortic aneurysm (>=5 cm) between 1998 and 2015 were identified in a database search. Two groups of patients were formed based on the type of procedure: 131 EVAR patients (median age 83 years; 114 men) and 46 OSR patients (median age 82 years; 35 men). RESULTS: The median follow-up was 5 years for the OSR group and 4.5 years for the EVAR group. Kaplan-Meier analysis showed no significant difference in survival between the EVAR and OSR groups at 78 months. The observed survival of all study patients was not statistically different from the expected survival of a sex- and age-matched German population, which was true separately for women and men. CONCLUSION: The patients in this study seemed to reach normal life expectancy in comparison to the age- and sex-matched general population with a similar cumulative survival in both study groups over 5 years of follow-up. PMID- 29466898 TI - The antiepileptic and neuroprotective effect of the Buxus hyrcana Pojark hydroethanolic extract against the pentylentetrazol induced model of the seizures in the male rats. AB - AIMS: The genus Buxus grows up widespread in Europe and Western Asia. It is an important traditional plant that has been used in the treatment of many illnesses. In the present study, the effect of hydroethanolic extract of Buxus hyrcana Pojark (BHP) on the animal model of seizure was studied. MATERIALS AND METHODS: In this experimental study, 42 male Wistar rats weighing 220-250 g were randomly selected and were divided into experimental and control groups (six rats per group). The experimental groups were treated by the intraperitoneal (i.p.) single injection of 150, 300, 450, 600 and 750 mg kg-1 of hydroalcoholic extracts of BHP. The control negative group received normal saline (0.9%) and the control positive group received phenobarbital (30 mg kg-1, i.p.) pre-treatment. Thirty minutes after the treatments, the seizure behaviors were evaluated by the pentylenetetrazole (PTZ) (70 mg kg-1, i.p.) challenge. In addition, after the experiment, the rats were put to death and their brains were removed for the histological study. RESULTS: The ANOVA demonstrated that compared to the control group, all the BHP doses delayed the initiation and duration of the tonic, colonic and tonic-colonic seizures and significantly reduced the tonic and colonic seizures (p < 0.001). Furthermore, the administration of all five doses of the extract significantly prevented the production of the dark neurons (p < 0.001) in different areas of the hippocampus compared to PTZ group. CONCLUSION: We can conclude that the BHP extract has beneficial effects for the prevention of the PTZ induced seizure. PMID- 29466899 TI - Kristeller maneuvers or fundal pressure and maternal/neonatal morbidity: obstetric and judicial literature review. AB - AIM: A significant amount of data concerning maternal-fetal damage arising from the exertion of Kristeller maneuvers (KMs) or fundal pressure (FP) go unreleased due to medicolegal implications. MATERIALS AND METHODS: For this reason, the paper gathers information as to the real magnitude of litigation related to FP induced damages and injuries. The authors have undertaken a research in order to include general search engines (PubMed-Medline, Cochrane, Embase, Google, GyneWeb) and legal databases (De Jure, Italian database of jurisprudence daily update; Westlaw, Thomson Reuters, American ruling database and Bailii, UK Court Ruling Database). RESULTS: Results confirm said phenomenon to be more wide ranging than it appears through official channels. Several courts of law, both in the United States of America (USA) and in European Union (EU) Member States as well, have ruled against the use of the maneuver itself, assuming a stance conducive to a presumption of guilt against those doctors and healthcare providers who resorted to KMs or FP during deliveries. Given how rife FP is in mainstream obstetric practice, it is as if there were a wide gap between obstetric real-life and what official jurisprudence and healthcare institutions sanctioned official practices are. CONCLUSION: The authors think that it would be desirable to draft specifically targeted guidelines or recommendations on maneuvers during vaginal delivery, in which to point out exactly what kinds of maneuvering techniques are to be absolutely banned and what maneuvers are to be allowed, and under what conditions their application can be considered appropriate. PMID- 29466900 TI - Influence of MMP inhibitor GM6001 loading of fibre coated polypropylene meshes on wound healing: Implications for hernia repair. AB - Polypropylene meshes are standard for hernia repair. Matrix metalloproteinases play a central role in inflammation. To reduce the inflammatory response and improve remodelling with an associated reduction of hernia recurrence, we modified polypropylene meshes by nanofibre coating and saturation with the broad spectrum matrix metalloproteinase inhibitor GM6001. The aim was to modulate the inflammatory reaction, increase collagen deposition and improve mesh biointegration. Polypropylene meshes were surface-modified with star-configured NCO-sP(EO -stat-PO) and covered with electrospun nanofibres (polypropylene-nano) and GM6001 (polypropylene-nano-GM). In a hernia model, defects were reconstructed with one of the meshes. Inflammation, neovascularization, bio-integration, proliferation and apoptosis were assessed histologically, collagen content and gelatinases biochemically. Mesh surface modification resulted in higher inflammatory response compared to polypropylene. Pro-inflammatory matrix metalloproteinase-9 paralleled findings while GM6001 reduced matrix metalloproteinase-9 significantly. Significantly increased matrix metalloproteinase-2 beneficial for remodelling was noted with polypropylene-nano meshes. Increased vascular endothelial growth factor, neo-vascularization and collagen content were measured in polypropylene-nano-meshes compared to polypropylene. GM6001 significantly reduced myofibroblasts. This effect ended after d14 due to engineering limitations with release of maximal GM6001 loading. Nanofibre-coating of polypropylene-meshes confers better tissue vascularization to the cost of increased inflammation. This phenomenon can be only partially compensated by GM6001. Future research will enable higher GM6001 uptake in nano coated meshes and may alter mesh biointegration in a more pronounced way. PMID- 29466901 TI - Modified ISTH pregnancy-specific DIC score in parturients with liver rupture: population-based case series. AB - OBJECTIVES: Liver rupture and hematoma are rare life-threatening complications of pregnancy. The aims of the current study are to: (1) characterize in a population based study all cases of liver hematoma and/or rupture; and (2) validate the utility of the International Society on Thrombosis and Haemostasis (ISTH) modified pregnancy specific disseminated intravascular coagulation (DIC) score in those cases. STUDY DESIGN: A retrospective cohort study including all patients with liver subcapsular hematoma or rupture between the years 1996 and 2012 was conducted. Information on maternal characteristics, clinical presentation, diagnostic studies, therapeutic modalities, as well as maternal and fetal outcomes was collected. The pregnancy-specific modified ISTH DIC scores were calculated from admission to discharge, a score >26 is suggestive of DIC. RESULTS: Out of 175,000 births in our database, seven patients were identified with liver rupture or subcapsular hematoma, representing a prevalence of 4:100,000 deliveries. Of those, six had liver rupture and one had subcapsular liver hematoma. One patient died of hemorrhagic shock. Four patients underwent surgical liver packing and one also underwent hepatic artery ligation. Four out of seven patients were diagnosed during the immediate postpartum period with severe features of preeclampsia or with hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome. Modified ISTH pregnancy-specific DIC scores were calculated for five out of seven patients, and three (60%) had a score higher than 26. Patients with higher scores received more blood product transfusions, had longer hospitalizations, and their neonates had lower 1 and 5 minutes Apgar scores. CONCLUSIONS: Elevated pregnancy-specific modified ISTH DIC score (>26) in patients with liver hematoma or rupture was associated with adverse maternal and neonatal outcomes and appeared to perform well in distinguishing high and low-risk cases. Postpartum preeclampsia may be associated with severe features and a more complicated disease course. PMID- 29466902 TI - Aberrant left subclavian artery occlusion in right-sided aortic artery associated with left cerebral infarction: A case report. AB - Purpose Right-sided aortic arch is a rare vessel anomaly with an incidence of 0.1% worldwide. Supra-aortic branches form a mirror image of the left-sided aortic arch or an aberrant left subclavian artery associated with Kommerell diverticulum. Most patients are diagnosed by a difference in blood pressure in each upper extremity or by the presence of left subclavian steal syndrome in their younger age. The diagnosis of onset of ischemic stroke in middle age is rare. Methods We present the case of a female patient who presented with an ischemic stroke in the left posterior circulation area. She had no history of congenital heart malformation. We performed head magnetic resonance imaging, cerebral angiography, and enhanced computed tomography of the aortic arch and major branches. Results The patient had a right-sided aortic arch and an aberrant left subclavian artery. The left subclavian artery was occluded at the proximal portion with a fibrous string. Collateral flow in the anterior cervical subcutaneous area supported left limb perfusion. Conclusion An atheromatous change reduced shunt flow via collateral networks at the anterior cervical region. Congenital subclavian steal supported the ischemic stroke. PMID- 29466905 TI - Corrigendum.

AB - Endovascular coiling for intracranial aneurysms has become an accepted treatment with good clinical results and provides adequate protection against rebleeding and rupture of aneurysms. However, despite the experience, preparation, or skill of the physician, complications during endovascular treatment still occur. The main complications of endovascular coiling are: procedural aneurysmal perforations by the microcatheter, micro-guidewire, or coil, and thromboembolic events. Such situations are unexpected, complex, and can have devastating consequences. In this article, we present a comprehensive review of the two most common complications, aneurysmal perforation and thromboembolism during endovascular coiling, and how we can prevent or overcome these complications to achieve a satisfactory outcome. In addition, as the flow diverter has been become an important tool for management of large, wide necked, and other anatomically challenging aneurysms, we also describe complications stemming from the use of the tool, which remains a novel treatment option for complex aneurysms. PMID- 29466904 TI - Effect of metal artifact reduction software on image quality of C-arm cone-beam computed tomography during intracranial aneurysm treatment. AB - Background and purpose C-arm cone-beam computed tomography (CBCT) has the drawback that image quality is degraded by artifacts caused by implanted metal objects. We evaluated whether metal artifact reduction (MAR) prototype software can improve the subjective image quality of CBCT images of patients with intracranial aneurysms treated with coils or clips. Materials and methods Forty four patients with intracranial aneurysms implanted with coils (40 patients) or clips (four patients) underwent one CBCT scan from which uncorrected and MAR corrected CBCT image datasets were reconstructed. Three blinded readers evaluated the image quality of the image sets using a four-point scale (1: Excellent, 2: Good, 3: Poor, 4: Bad). The median scores of the three readers of uncorrected and MAR-corrected images were compared with the paired Wilcoxon signed-rank and inter reader agreement of change scores was assessed by weighted kappa statistics. The readers also recorded new clinical findings, such as intracranial hemorrhage, air, or surrounding anatomical structures on MAR-corrected images. Results The image quality of MAR-corrected CBCT images was significantly improved compared with the uncorrected CBCT image ( p < 0.001). Additional clinical findings were seen on CBCT images of 70.4% of patients after MAR correction. Conclusion MAR software improved image quality of CBCT images degraded by metal artifacts. PMID- 29466906 TI - Melanin Bleaching With Warm Hydrogen Peroxide and Integrated Immunohistochemical Analysis: An Automated Platform. AB - OBJECTIVE: Diagnosing melanocytic lesions is among the most challenging problems in the practice of pathology. The difficulty of physically masking melanin pigment and the similarity of its color to commonly used chromogens often complicate examination of the cytomorphology and immunohistochemical staining results for tumor cells. Melanin bleach can be very helpful for histopathological diagnosis of heavily pigmented melanocytic lesions. Although various depigmentation methods have been reported, no standardized methods have been developed. This study developed a fully automated platform that incorporates hydrogen peroxide-based melanin depigmentation in an automated immunohistochemical analysis. METHODS AND MATERIALS: The utility of the method was tested in 1 cell block of malignant melanoma cells in pleural effusion, 10 ocular melanoma tissue samples, and 10 cutaneous melanoma tissue samples. Our results demonstrated that the proposed method, which can be performed in only 3 hours, effectively preserves cell cytomorphology and immunoreactivity. RESULTS: The method is particularly effective for removing melanin pigment to facilitate histopathological examination of cytomorphology and for obtaining an unmasked tissue section for immunohistochemical analysis. PMID- 29466907 TI - Teaching forensic pathology to undergraduates at Zhongshan School of Medicine. AB - Producing qualified forensic pathological practitioners is a common difficulty around the world. In China, forensic pathology is one of the required major subspecialties for undergraduates majoring in forensic medicine, in contrast to forensic education in Western countries where forensic pathology is often optional. The enduring predicament is that the professional qualities and abilities of forensic students from different institutions vary due to the lack of an efficient forensic pedagogical model. The purpose of this article is to describe the new pedagogical model of forensic pathology at Zhongshan School of Medicine, Sun Yat-sen University, which is characterised by: (a) imparting a broad view of forensic pathology and basic knowledge of duties and tasks in future careers to students; (b) educating students in primary skills on legal and medical issues, as well as advanced forensic pathological techniques; (c) providing students with resources to broaden their professional minds, and opportunities to improve their professional qualities and abilities; and (d) mentoring students on occupational preparation and further forensic education. In the past few years, this model has resulted in numerous notable forensic students accomplishing achievements in forensic practice and forensic scientific research. We therefore expect this pedagogical model to establish the foundation for forensic pathological education and other subspecialties of forensic medicine in China and abroad. PMID- 29466908 TI - Double suicide in modern Japan (in Kanagawa prefecture): Comparison with those in post-war Japan and other countries. AB - Double-suicide cases have long been common in Japan, particularly among lovers. Classical studies conducted in the 1950s are well known. According to a report by Ohara, the double-suicide rate in Japan was recorded as 3.1% in 1954. Nevertheless, recent tendencies have not been reported. To assess the latest trends of double suicide, extensive studies were conducted in a populous area of Kanagawa, Japan, during 1999-2011. Suicides during the period in the domestic area claimed 23,195 victims. In all, 82 cases of double suicide were extracted, with 170 victims, meaning that double suicides occurred with incidence of 0.73% among all suicides. The mean age and standard deviation were 51.6+/-16.1 years, with 83 men and 87 women. The suicide-partner relationships included 40 cases (48.8%) of married couples, 13 (15.9%) of unmarried lovers, and 10 (12.2%) of elderly woman and her son/daughter dyads. No significant difference was found from Western countries in the incidence of double-suicide cases in Japan, except for a higher incidence of suicide involving elderly people and their sons/daughters. The traditional style of double suicide by lovers has become less frequent in modern Japanese society, presumably because of changing marriage styles and values. PMID- 29466909 TI - Skin Conductance Responses to Masked Emotional Faces Are Modulated by Hit Rate but Not Signal Detection Theory Adjustments for Subjective Differences in the Detection Threshold. AB - The biological preparedness model suggests that survival-related visual cues elicit physiological changes without awareness to enable us to respond to our environment. Previous studies have reported some evidence for this effect. In the current article, we argue that this evidence is subject to methodological confounds. These include the use of a universal masked presentation threshold, the employment of hit rates (HRs) to measure meta-awareness, and the assertion of overall guess-level target detection using nonsignificance. In the current report, we address these issues and test whether masked emotional faces can elicit changes in physiology. We present participants with subjectively adjusted masked angry, fearful, happy, and neutral faces using HRs and signal detection theory. We assess detection performance using a strict Bayesian criterion for meta-awareness. Our findings reveal that HR adjustments in the detection threshold allow higher skin conductance responses to happy, fearful, and angry faces, but that this effect could not be reported by the same participants when the adjustments were made using signal detection measures. Combined these findings suggest that very brief biologically relevant stimuli can elicit physiological changes but cast doubt to the extent that this effect can occur in response to truly unconscious emotional faces. PMID- 29466910 TI - The Role of Ventral Tegmental Area Gamma-Aminobutyric Acid in Chronic Neuropathic Pain after Spinal Cord Injury in Rats. AB - Spinal cord injury (SCI) frequently results in chronic neuropathic pain (CNP). However, the understanding of brain neural circuits in CNP modulation is unclear. The present study examined the changes of ventral tegmental area (VTA) putative GABAergic and dopaminergic neuronal activity with CNP attenuation in rats. SCI was established by T10 clip compression injury (35 g, 1 min) in rats, and neuropathic pain behaviors, in vivo extracellular single-cell recording of putative VTA gamma-aminobutyric acid (GABA)/dopamine neurons, extracellular GABA level, glutamic acid decarboxylase (GAD), and vesicular GABA transporters (VGATs) were measured in the VTA, respectively. The results revealed that extracellular GABA level was significantly increased in the CNP group (50.5 +/- 18.9 nM) compared to the sham control group (10.2 +/- 1.7 nM). In addition, expression of GAD65/67, c-Fos, and VGAT exhibited significant increases in the SCI groups compared to the sham control group. With regard to neuropathic pain behaviors, spontaneous pain measured by ultrasound vocalizations (USVs) and evoked pain measured by paw withdrawal thresholds showed significant alteration, which was reversed by intravenous (i.v.) administration of morphine (0.5-5.0 mg/kg). With regard to in vivo electrophysiology, VTA putative GABAergic neuronal activity (13.6 +/- 1.7 spikes/sec) and putative dopaminergic neuronal activity (2.4 +/- 0.8 spikes/sec) were increased and decreased, respectively, in the SCI group compared to the sham control group. These neuronal activities were reversed by i.v. administration of morphine. The present study suggests that chronic increase of GABAergic neuronal activity suppresses dopaminergic neuronal activity in the VTA and is responsible for negative emotion and motivation for attenuation of SCI induced CNP.

AB - BACKGROUND: There is an absence of studies exploring different goal-setting appraches and none which have examined the use of proxy goal-setting by parents for their children. AIM: To explore how proficient parents are in setting health behaviour goals for their children according to SMART (specific, measurable, achievable, realistic and time-framed) goal principles. A secondary aim was to examine associations between goal setting and change in health behaviors. METHODS: Participants were parents and children taking part in one of two trials incorporating goal setting. Study 1 ( Time2bHealthy) was an online program for parents of preschoolers ( n = 36) and Study 2 ( HIKCUPS) was a three-arm face-to face trial examining a parent-centered dietary intervention, (Study2Diet); a child-centered physical activity intervention, (Study2PA); or combination of both (Study2Combo) ( n = 83). Goals were coded on five 'SMART' principles. Goals were scored 1 or 0 for each principle (1 indicated the principle was met and 0, not met). The total maximum score for each goal was 5. Mean total goal-score and means for each SMART principle were calculated. RESULTS: Mean (and standard deviation) goal setting scores for Study 1 were 3.84 (0.61), Study2Diet 2.17 (1.33), Study2PA 3.18 (1.45) and Study2Combo 2.24 (1.30). Goal-scores were significantly higher for Study 1 than Study 2 ( p < 0.001). In Study2Diet, goal setting was significantly associated with greater reduction in energy intake ( p = 0.019). CONCLUSIONS: Goal-scores were highest in Study 1, which used a supported online format for setting goals. Parents were better at setting physical activity goals, but these goals did not translate into improvements in physical activity behavior. Goals set by parents may be useful in energy intake reduction, however further research is required to determine benefits for weight status or physical activity. PMID- 29466912 TI - Radial shaft fracture obliquity as a predictor of distal radioulnar joint instability. AB - : We assessed whether radial shaft fracture obliquity measurements on radiographs could predict intra-operative distal radioulnar joint instability. We also clinically validated previously described predictors of distal radioulnar joint instability, which included a fracture line within 7.5 cm of the lunate fossa, radial shortening >5 mm, and ulna styloid fracture. We retrospectively analysed the radiographs of all surgically managed patients in our unit with radial shaft fractures from 2006 through 2016. The degree of obliquity was analysed on the basis of the maximum fracture-line angle in either the coronal or the sagittal plane. A radial shaft fracture obliquity >30 degrees is predictive of distal radioulnar joint instability ( P = 0.001). Radial fracture shaft obliquity >30 degrees was the most sensitive radiological parameter (76%) for predicting distal radioulnar joint instability. Oblique radial shaft fractures appear to be associated with increased incidence of distal radioulnar joint instability. This radiologic parameter may be used together with established parameters in predicting distal radioulnar joint instability for surgical treatment. LEVEL OF EVIDENCE: III. PMID- 29466913 TI - Screening for cognitive impairment in SLE using the Self-Administered Gerocognitive Exam. AB - Objective Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease that can affect the central nervous system in multiple ways, including causing cognitive dysfunction. Cognitive dysfunction is a common complaint of SLE patients yet diagnosis is challenging, time consuming, and costly. This study evaluated the Self-Administered Gerocognitive Exam (SAGE) as a screening test for cognitive impairment in a cohort of SLE patients. Methods A total of 118 SLE patients completed the SAGE. Providers completed the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) and the Systemic Lupus International Collaborative Clinics Damage Index (SLICC-DI). SAGE scores were grouped into normal (>16) and abnormal (<=16) categories. Univariate and multivariate analyses were performed. Results Of the 118 participants, 21(18%) scored <=16 on the SAGE instrument. In univariate analysis, race, ethnicity, household income, and SLICC DI scores were associated with the SAGE ( p < 0.05). In multivariable analysis, abnormal SAGE score was independently associated with higher SLICC-DI score (odds ratio (OR) = 1.44, 95% confidence intervals 1.04-1.99, p = 0.03)), Hispanic ethnicity (OR = 43.4, 95% CI 3.1-601, p = 0.005), and lower household income (OR = 11.9 for <=$15,000 vs >$50,000, 95% CI 2.45-57, p = 0.002). Conclusions In SLE patients, this study demonstrates an independent relationship between neurocognitive impairment (as measured by the SAGE) and higher lupus-related damage, as measured by the SLICC-DI, and lower household income. Abnormal SAGE scores were also associated with Hispanic ethnicity. A language barrier could explain this because the SAGE instrument was conducted in English only. The SAGE was feasible to measure in the clinic setting. PMID- 29466915 TI - Effects of Sexual Media Literacy Education for School Nurses in South Korea. AB - This study aimed to examine the effects of a sexual education program (SEP) focused on sexual media literacy (SML) for school nurses. A quasi-experimental, pre-/posttest design was used to examine SML knowledge, awareness, reinterpretation skill, and self-efficacy. A total of 66 school nurses participated. The experimental group ( n = 35) participated in an 18-hr SEP that focused on SML, while the control group ( n = 31) did not. The experimental group showed significant improvement in knowledge ( t = 6.47, d = 1.62, p < .001), awareness ( t = 5.08, d = 1.19, p < .001), reinterpretation skill ( t = 4.81, d = 2.28, p < .001), and self-efficacy ( t = 8.29, d = 1.38, p < .001) as compared to the control group. The SEP developed in this study may be an effective educational intervention for school nurses. PMID- 29466914 TI - Inducible CRISPR genome editing platform in naive human embryonic stem cells reveals JARID2 function in self-renewal. AB - To easily edit the genome of naive human embryonic stem cells (hESC), we introduced a dual cassette encoding an inducible Cas9 into the AAVS1 site of naive hESC (iCas9). The iCas9 line retained karyotypic stability, expression of pluripotency markers, differentiation potential, and stability in 5iLA and EPS pluripotency conditions. The iCas9 line induced efficient homology-directed repair (HDR) and non-homologous end joining (NHEJ) based mutations through CRISPR Cas9 system. We utilized the iCas9 line to study the epigenetic regulator, PRC2 in early human pluripotency. The PRC2 requirement distinguishes between early pluripotency stages, however, what regulates PRC2 activity in these stages is not understood. We show reduced H3K27me3 and pluripotency markers in JARID2 2iL-I-F hESC mutants, indicating JARID2 requirement in maintenance of hESC 2iL-I-F state. These data suggest that JARID2 regulates PRC2 in 2iL-I-F state and the lack of PRC2 function in 5iLA state may be due to lack of sufficient JARID2 protein. PMID- 29466916 TI - Augmented migration of mesenchymal stem cells correlates with the subsidiary CXCR4 variant. AB - Use of mesenchymal stem cells (MSCs) has been introduced as a promising tool, for structural and functional recovery of damaged tissues/organs. Studies have indicated that interactions between chemokine receptors and their ligands have a critical role in homing of MSCs to the site of injury. Although CXCR4 variants have been characterized, the exact role of each transcript in homing has remained unclear. In this study, cells were pretreated with various hypoxia-mimicking compounds (valproic acid, cobalt-chloride, and deferoxamine mesylate). Results indicated that both variants of CXCR4 were overexpressed after 24 hours of treatments and their expression could cooperatively induce and promote the cell migration. Moreover, deferoxamine mesylate was more effective in overexpression of variant A (lo), which resulted in higher level of CXCR4 protein and the highest rate of migration of the cells. In conclusion, our findings may have important potential implications in clinical applications, reinforcing the concept that manipulating the expression of specific CXCR4 variants may increase migration of MSCs. PMID- 29466917 TI - Cure of chronic hepatitis C virus infection in an HIV-coinfected patient with multiple comorbidities and drug interaction challenges. AB - Curing hepatitis C virus (HCV) infection in patients harbouring multiple severe comorbidities is a medical challenge. Evidence-based data are lacking regarding HCV treatment with direct-acting antiviral regimens in particular populations of HCV/HIV-coinfected patients with cirrhosis and chronic kidney disease on haemodialysis. Here, we present the HCV treatment challenges facing a patient with HIV coinfection, prior failure of both HIV-1 and HCV therapy, cirrhosis, end stage renal failure on haemodialysis, as well as management of drug-drug interactions, especially given the need to receive long-term amiodarone therapy. PMID- 29466918 TI - Multiple sclerosis and HIV: a case of multiple sclerosis-immune reconstitution inflammatory syndrome associated with antiretroviral therapy initiation. AB - Studies have suggested that the incidence of multiple sclerosis (MS) in HIV infected (HIV+) patients is lower than that of the general population. Here, we present a case of MS in an HIV+ patient with a relatively suppressed CD4 cell count who developed clinical and radiographic disease worsening in the setting of antiretroviral therapy (ART) initiation. A 47-year-old HIV+ woman (CD4 cell count 216 cells/ul) presented with decreased vision in her right eye. Magnetic resonance imaging (MRI) revealed optic nerve enhancement and open ring-enhancing lesions in the brain concerning for demyelinating disease. Cerebrospinal fluid was tested extensively for infection and malignancy with no abnormal findings. She received five days of intravenous methylprednisolone. Nine days later, she was restarted on ART. Three weeks later, she was readmitted with left eye vision loss and left hemiplegia (CD4 cell count 342 cells/ul). Repeat imaging showed multiple new enhancing lesions. Several cases have described severe MS relapses and unusually widespread demyelinating lesions on MRI after withdrawal of immunosuppressive drugs. We posit that the clinical and radiographic progression that occurred in our patient after initiation of ART represented an immune reconstitution response to ART. Caution may be warranted when initiating ART in HIV+ patients with suppressed CD4 cell count and active MS. PMID- 29466919 TI - What qualities in a potential HIV pre-exposure prophylaxis service are valued by black men who have sex with men in London? A qualitative acceptability study. AB - Black men who have sex with men (BMSM) have higher HIV incidence and prevalence when compared to other MSM, despite similar levels of condom use and testing. Pre exposure prophylaxis (PrEP) could be a useful intervention to reduce these inequalities. This research therefore aims to understand the dimensions of acceptability of a potential PrEP service for BMSM aged 18-45 years in London. In depth semi-structured interviews were conducted with 25 PrEP-eligible BMSM between April and August 2016. Interviews were recorded and transcribed verbatim, then subject to a thematic framework analysis, informed by intersectionality theory. BMSM had distinct preferences for sexual health services, which have implications for PrEP service development. Three primary domains emerged in our analysis: proximity and anonymity; quality, efficiency and reassurance; and understanding, empathy and identity. These relate, respectively, to preferences regarding clinic location and divisions from community, features of service delivery and staff characteristics. Due to concerns about confidentiality, community-based services may not be useful for this group. Careful consideration in regards to components used in service development will facilitate ongoing engagement. Interpersonal skills of staff are central to service acceptability, particularly when staff are perceived to be from similar cultural backgrounds as their patients. PMID- 29466920 TI - Trajectory of Functional Independent Measurements during First Five Years after Moderate and Severe Traumatic Brain Injury. AB - A better understanding of long-term functional recovery process for patients with traumatic brain injury (TBI) facilitates effective rehabilitations. The aim of this study was to classify and characterize patients with moderate-to-severe TBI based on their functional trajectories up to 5 years post-injury. The study included 121 patients with moderate-to-severe TBIs (International Classification of Diseases, Tenth Revision [ICD-10], S06.0-S06.9), 16-55 years of age, and admitted at Trauma Referral Hospital within 24 h of injury between 2005 and 2007. Demographics and injury characteristics were documented at the admission, and functional status was recorded at 3 months and 1 and 5 years post-injury using Functional Independence Measure motor (FIM-M) and cognitive (FIM-C) subscales. We used group-based trajectory models to classify patients' functional trajectories over a 5-year period. For FIM-M, three trajectories were identified: 8.2% of patients showed stable low recovery (13.6 +/- 1.5, 17.9 +/- 8.8, and 21.0 +/- 17.9), 9.2% elevated good recovery (35.8 +/- 14.5, 75.5 +/- 12.4, and 85.5 +/- 8.1), and 82.6% stable good recovery (89.0 +/- 3.6, 90.3 +/- 1.9, and 90.8 +/- 1.0) at the three follow-up points, respectively. For FIM-C, four trajectories were revealed: 4.1% of patients showed stable low recovery (5.0 +/- 0, 5.0 +/- 0, and 5.0 +/- 0), 12.6% delayed moderate recovery (8.9 +/- 3.5, 20.6 +/- 4.6, and 28.3 +/- 3.8), 28.7% elevated good recovery (27.0 +/- 3.8, 30.4 +/- 7.3, and 31.1 +/- 2.3), and 54.6% stable good recovery (32.8 +/- 2.3, 34.6 +/- 1.0, and 34.7 +/ 1.0). The results suggest that three FIM-M and four FIM-C trajectories described various patterns of functional recovery 5 years after moderate-to-severe TBI, with stable good recovery being the most common trajectory. Identifying and characterizing the trajectory memberships should enable targeted rehabilitation programs, inform patient-centered care, and improve long-term outcomes. PMID- 29466921 TI - The confabulation battery: Instructions and international data from normal participants. AB - Confabulation is an unusual sign in neurological and in neuropsychological pathologies. In this article we present an objective neuropsychological instrument, the Confabulation Battery (CB), which allows the quantifying and qualifying of different types of confabulations. The CB was administered to French and Italian normal participants. Data from the present study will allow clinicians and researchers, using the CB, to know how much and in which memory domains their confabulating patients confabulate compared to normal participants. We present international data, instructions and guidelines for the CB, a tool used in different ways worldwide. Not quantifying confabulations, namely not reporting how much and in which domain patients confabulate, can hardly lead to conclusions on the neurocognitive bases of this phenomenon. Following the instructions in this article, versions of the CB can be adapted in different languages and cultures. Quantification and qualification of confabulation is necessary and demanded in order to compare sensibly data from different research and clinical groups. PMID- 29466922 TI - Rabbit Calvarial Defect Model for Customized 3D-Printed Bone Grafts. AB - Bone graft materials are commonly used to regenerate various bone defects, but their application is often limited because of the complex defect shape in various clinical conditions. Hence, customized bone grafts using three-dimensional (3D) printing techniques have been developed. However, conventional simple bone defect models are limited for evaluating the benefits and manufacturing accuracy of 3D printed customized bone grafts. Thus, the aim of the present study was to develop a complex-shaped bone defect model. We designed an 8-shaped bony defect that consists of two simple circles attached to the rabbit calvarium. To determine the critical-sized defect (CSD) of the 8-shaped defects, 5.6- and 7-mm-diameter trephine burs were tested, and the 7-mm-diameter bur could successfully create a CSD, which was easily reproducible on the rabbit calvarium. The rate of new bone formation was 28.65% +/- 8.63% at 16 weeks following creation of the defect. To confirm its efficacy for clinical use, the 8-shaped defect was created on a rabbit calvarium and 3D computed tomography (CT) was performed. A stereolithography file was produced using the CT data, and a 3D-printed polycaprolactone graft was fabricated. Using our 8-shaped defect model, we were able to modify the tolerances of the bone graft and calvarial defect to fabricate a more precise bone graft. Customized characteristics of the bone graft were then used to improve the accuracy of the bone graft. In addition, we confirmed the fitting ability of the 3D-printed graft during implantation of the graft. Our 8 shaped defect model on the rabbit calvarium using a 7.0-mm trephine bur may be a useful CSD model for evaluating 3D-printed graft materials. PMID- 29466923 TI - Impact of a Standardized Beta-Lactam Allergy Questionnaire on Aztreonam Use. AB - METHODS: This quasi-experimental study compared the aztreonam utilization in patients with self-reported beta-lactam allergies admitted to an inpatient service between two study periods (pre- and post-implementation). Post implementation followed the initiation of a standardized beta-lactam allergy questionnaire, a student pharmacist-driven performance improvement project for beta-lactam allergy documentation. Interviews clarified the allergy, reaction history, and any previous tolerance of beta-lactams. If receiving aztreonam at the time of the questionnaire, recommendations were made for changes in therapy if deemed appropriate by the pharmacist. RESULTS: A total of 95 patients were included in the pre-implementation group versus 65 patients in the post implementation group. Baseline characteristics were similar. The average number of aztreonam doses per 1000 patient-days in the post-implementation group was decreased (21.23 vs 9.05, P = .003). The average number of days of therapy per 1000 patient-days in the post-implementation group was decreased (8.79-4.24, P = .016). An increase in the number of aztreonam de-escalations was observed post implementation ( P = .003). A total of 122 questionnaires were completed with 114 allergy documentation updates. There were no reported instances of adverse events. CONCLUSION: Utilization of a standardized beta-lactam allergy questionnaire as a pharmacy education tool resulted in a statistically significant decrease in aztreonam utilization, based on doses, days of therapy, and de-escalations. PMID- 29466924 TI - Ventriculoatrial synchrony induced heart failure. AB - OBJECTIVE AND IMPORTANCE: Endless loop tachycardia or pacemaker-mediated tachycardia, and atrioventricular desynchronization arrhythmia or repetitive non reentrant ventriculoatrial synchrony (RNRVAS) are two forms of reverse impulse conduction - ventriculoatrial (VA) synchrony. Although VA synchrony can theoretically cause aggravation of heart failure, clinical cases describing severe consequential heart failure are lacking. CLINICAL PRESENTATION AND INTERVENTION: We describe a case of a 60-year-old patient who underwent primary percutaneous coronary intervention and mitral valve surgery. Implantation of a two-chamber pacemaker was also performed during the same hospitalization due to development of third-degree atrioventricular block. Ten months later, he presented with a severe form of heart failure with a significant reduction of left ventricular ejection fraction (LVEF). The atrial lead was displaced and VA synchrony was registered (RNRVAS-like condition). The pacemaker was reprogrammed and VA synchrony induced heart failure was successfully resolved. Echocardiographic follow-up showed improvement in LVEF. CONCLUSION: Ventriculoatrial conduction can be present even when the patient has a complete atrioventricular block. Atrial lead displacement and consequently loss of atrial capture with preserved sensing can be a predisposing factor for initiation of ventriculoatrial synchrony. Permanent ventriculoatrial synchrony may provoke aggravation of heart failure. PMID- 29466925 TI - Peripheral VA-ECMO with direct biventricular decompression for refractory cardiogenic shock. AB - Cardiogenic shock and cardiac arrest are life-threatening emergencies that result in high mortality rates. Veno-arterial extracorporeal membrane oxygenation (VA ECMO) via peripheral cannulation is an option for patients who do not respond to conventional therapies. Left ventricular (LV) distention is a major limitation with peripheral VA-ECMO and is thought to contribute to poor recovery and the inability to wean off VA-ECMO. We report on a novel technique that combines peripheral VA-ECMO with off-pump insertion of a trans-apical LV venting cannula and a right ventricular decompression cannula. PMID- 29466926 TI - Pulling force prediction using neural networks. AB - PURPOSE: In ergonomics and human factors investigations, pulling force (PF) estimation has usually been achieved using various types of biomechanical models, and independent approximation of PF was done with the help of upper extremity joints. Recently, multiple regression methods have gained importance for task relevant inputs in predicting PF. Artificial neural networks (ANNs) also play a vital role in fitting the data; however, their use in work-related biomechanics and ergonomics is inadequate. Therefore, the current research aimed to accomplish comparative investigation of ANN and regression models by assessing their capacity to predict PF values. METHODS: Multipositional PF data were acquired from 200 subjects at three different handle heights and body locations. ANN and regression models were formed using a random sample of three subsets (75% training, 15% selection, 10% validation) for proving the outcomes. RESULTS: The comparison of ANN and regression models shows that the predictions of ANN models had a profoundly explained variance and lower root mean square difference values for the PF data at three handle heights. CONCLUSIONS: These outcomes advise that ANNs offer a precise and robust substitute for regression methods, and should be considered a useful method in biomechanics and ergonomics task assessments. PMID- 29466927 TI - "We own the illness": a qualitative study of networks in two communities with mixed ethnicity in Northern Norway. AB - BACKGROUND: When people in Northern Norway get ill, they often use traditional medicine. The global aim of this study was to examine the extended family networks' function and responsibility in cases of illness in the family, in two Northern Norwegian communities with a population of mixed ethnicity. METHODS: Semi-structured individual interviews with 13 participants and 4 focus group interviews with total 11 participants were conducted. The text data was transcribed verbatim and analysed based on the criteria for content analysis. RESULTS: The participants grew up in areas where it was common to seek help from traditional healers. They were organized in networks and shared responsibility for the patient and they provided practical help and support for the family. According to the networks, health-care personnel should make room for the entire network to visit the patient in severe and life-threatening situations. CONCLUSION: Traditional networks are an extra resource for people in these communities. The networks seem to be essential in handling and disseminating hope and manageability on an individual as well as a collective level. Health personnel working in communities with mixed ethnicity should have thorough knowledge of the mixed culture, including the importance of traditional network to the patients. PMID- 29466928 TI - Mapping patterns of change in emotion-focused psychotherapy: Implications for theory, research, practice, and training. AB - An important objective in humanistic-experiential psychotherapies and particularly emotion-focused psychotherapy (EFT) is to map patterns of change. Effective mapping of the processes and pathways of change requires that in session processes be linked to in-session resolutions, immediate post-session changes, intermediate outcome, final therapy outcome, and longer-term change. This is a challenging and long-term endeavour. Fine-grained descriptions of in session processes that lead to resolution of specific interpersonal and intrapersonal issues linked with longer-term outcomes are the foundation of EFT, the process-experiential approach. In this paper, evidence in support of EFT as a treatment approach will be reviewed along with research on two mechanisms of change, viewed as central to EFT, clients' emotional processing and the therapeutic relationship conditions. The implications for psychotherapy research are discussed. Given the methodological constraints, there is a need for more innovative methodologies and strategies to investigate specific psychotherapy processes within and across different approaches to map patterns and mechanisms of change to enhance theory, research, practice, and training. PMID- 29466929 TI - Histological Scoring Method to Assess Bone Healing in Critical Size Bone Defect Models. AB - Large bone defects are a major problem in trauma and orthopedic surgery. Tissue engineering based treatments have emerged as promising alternatives to traditional bone grafting techniques. Critical size bone defect animal models have been developed and widely used to evaluate and compare therapeutic effectiveness in bone tissue engineering treatments. To measure healing in a given defect after treatment, histological assessment methods are commonly used. These histological methods are typically qualitative and only measure the amount of newly formed bone. In this study, we introduce a new histological scoring method that in addition to new bone formation also measures newly formed "cartilage," "fibrous tissue," and "remnant bone defect size." Using Kappa analysis and interclass correlation analysis, we verified the reliability of our new scoring method. These additional parameters make it possible to differentiate between the hard callus and soft callus phases of healing and, thus, derive more valuable information about the effect different tissue-engineering treatments have on the healing process. PMID- 29466930 TI - Mechanism of MicroRNA-708 Targeting BAMBI in Cell Proliferation, Migration, and Apoptosis in Mice With Melanoma via the Wnt and TGF-beta Signaling Pathways. AB - OBJECTIVE: The aim of this study was to evaluate the mechanisms involved with miRNA-708 and its targeting of bone morphogenetic protein and activin membrane bound inhibitor in cell proliferation, migration, and apoptosis in mice with melanoma via the Wnt and transforming growth factor beta signaling pathways. METHODS: Sixty mice were recruited of which 40 were subsequently assigned into the experimental group (22 mice were successfully established as melanoma model and 18 mice used in tumor xenograft), and the normal control group consisted of 20 mice. B16 cells were assigned to the normal, blank, and negative control, miR 708 mimics, miR-708 inhibitors, si-BAMBI, and miR-708 inhibitors + si-bone morphogenetic protein and activin membrane-bound inhibitor groups. Western blotting and reverse transcription quantitative polymerase chain reaction were employed to detect the expression levels within the tissues and cell lines. TCF luciferase reporter (TOP-FLASH) or a control vector (FOP-FLASH) was applied to detect the activity of the Wnt signaling pathway. MTT3-(4,5-Dimethylthiazol-2-yl) 2,5 diphenyltetrazolium bromide assay, flow cytometry, scratch test, and Transwell assay were conducted, respectively, for cell proliferation, apoptosis, migration, and invasion, while tumor xenograft procedures were performed on the nude mice recruited for the study. RESULTS: Compared to the normal control group, the model group displayed increased expressions of bone morphogenetic protein and activin membrane-bound inhibitor, Wnt10B, P53, and Bcl-2; TOPflash activity; beta catenin expression; cell proliferation; migration; and invasion capabilities while decreased expressions of miR-708, vascular endothelial growth factor, Fas, Bax, Caspase-3, and cleaved Caspase-3 and apoptosis rate. Compared to the blank and negative control groups, the miR-708 mimics and small-interfering RNA-bone morphogenetic protein and activin membrane-bound inhibitor groups exhibited decreases expressions of bone morphogenetic protein and activin membrane-bound inhibitor, Wnt10B, P53, and Bcl-2 and decreased proliferation, migration, and invasion capabilities, while increases in the apoptosis rate, expressions of vascular endothelial growth factor, Fas, Bax, Caspase-3, and cleaved Caspase-3; however, downregulated levels of TOPflash activity and beta-catenin expression were recorded. The miR-708 inhibitors group displayed an opposite trend. CONCLUSION: Downregulation of miR-708-targeted bone morphogenetic protein and activin membrane-bound inhibitor inhibits the proliferation and migration of melanoma cells through the activation of the transforming growth factor beta pathway and the suppression of Wnt pathway. PMID- 29466931 TI - Comparative in vitro activity of ceftaroline and comparator agents against nosocomial Gram-negative and Gram-positive clinically significant bacterial isolates from patients in a teaching hospital in Kuwait. AB - The objective was to test the in vitro activities of ceftaroline and comparator agents against clinical isolates of Gram-negative and Gram-positive bacteria. Isolates were identified with VITEK II. Susceptibility testing was with E test. A total of 1264 isolates were tested. Compared to other cephalosporins, ceftaroline demonstrated excellent in vitro activities (MIC90, <=0.5 mg/L) against Escherichia coli, Salmonella spp. and Haemophilus influenzae. When matched with the comparator cephalosporins, ceftaroline demonstrated the greatest activity against methicillin-susceptible Staphylococcus aureus (MSSA), with MIC90 of 0.25 mg/L. Ceftaroline's MIC90s against both community-associated methicillin resistant S. aureus (MRSA) and hospital-acquired MRSA were 0.5 and 1 mg/L, respectively. Major discrepancies were noted between E test and disc diffusion tests for ceftaroline only against 16 Gram-negative and 16 Gram-positive isolates. Ceftaroline demonstrated an excellent in vitro activity against the majority of clinically significant Gram-negative and Gram-positive isolates obtained from proven cases of bacterial infections. PMID- 29466932 TI - A Single Radioactive Iodine Treatment Has a Deleterious Effect on Ovarian Reserve in Women with Thyroid Cancer: Results of a Prospective Pilot Study. AB - BACKGROUND: Women of reproductive age with differentiated thyroid cancer (DTC) often need radioactive iodine (RAI) treatment after surgery. In contrast to the well-documented effect of RAI on testicular function, the potential negative effects of this treatment on ovarian reserve have been largely dismissed. The objective of this pilot study was to examine the possibility that RAI treatment is deleterious to the ovarian reserve by prospectively measuring the concentration of anti-Mullerian hormone (AMH) after RAI treatment. METHODS: Thirty premenopausal women (Mage = 34 years; range 20-45 years) with a new diagnosis of DTC scheduled to undergo RAI ablation were recruited for this study. All of them had TNM stage 1 disease (T1-3, N0, or N1, M0), and were scheduled to receive RAI activities ranging from 30 to 150 mCi. AMH was measured at baseline and at 3, 6, 9, and 12 months after the administration of RAI. RESULTS: Of the 30 women, only 24 returned after the baseline assessment. RAI treatment resulted in a significant decrease in AMH concentrations at three months, from 3.25 +/- 2.75 to 1.9 +/- 1.74 ng/mL (p < 0.0001). Only partial recovery was subsequently documented. Eighty-two percent of subjects had final values below baseline levels, such that at one year, serum AMH was still 32% lower than prior to treatment (2.36 +/- 1.88 ng/mL; p < 0.005). The only two continuous variables that correlated with the extent of AMH reduction at three months were the woman's age (r = 0.51; p = 0.02) and the age at menarche (r = 0.48; p = 0.03). Importantly, the RAI dose was not associated with the extent of AMH reduction and neither were smoking or the use of birth control pills. Older subjects (>=35 years) were significantly more likely to experience a marked AMH reduction at three months (63.7 +/- 18.5% vs. 33.1 +/- 29.2%; p = 0.01). The only predictor of recovery after one year was the extent of AMH decrease at three months: the lower the decline, the higher the chances for recovery. CONCLUSIONS: RAI in DTC has a rapid and profound effect on ovarian reserve, with only a partial recovery potential. In an era of declining human fertility, it is of relevance to recognize the potentially adverse effect of RAI in women of reproductive age. AMH measurement may be useful as a tool in this decision-making process.

AB - Many issues, such as, DO accumulation, N2 fixation obstacle, and carbon dioxide diffusion, hamper the application of microalgae-alginate immobilization in wastewater treatment. The objective of this study was to evaluate the effect of the microalgae Nannochloropsis oculata immobilized with the bacterium Bacillus polymyxa in alginate on ammonium and phosphate removal from synthetic wastewater. Results show that the co-immobilized Bacillus-Nannochloropsis can exploit ammonium and phosphate from wastewater more effectively than the immobilized Nannochloropsis, and immobilized Bacillus alone. A significantly higher ammonium and phosphate removal efficiency was found in co-immobilized Bacillus Nannochloropsis (59.85%, 90.44%) than of that in immobilized Nannochloropsis (49.56%, 77.36%), and Bacillus immobilized (31.46%, 29.66%) alone. Additionally, the most effective co-immobilization mixture ratio for wastewater treatment was found to contain equal suspension (108 cell/ml) volume of the Nannochloropsis and Bacillus. Nannochloris and Bacillus can coexist harmoniously with the symbiotic and synergistic relationship, and the Nannochloropsis oculata- Bacillus polymyxa combination can be useful as a potential method to develop novel wastewater treatment.

AB - Objectives To evaluate 36-month outcomes of drug-eluting balloons in infrapopliteal (=below-the-knee) arterial segments, we made a prospective registry enrolling patients (Rutherford class 2 to 5, ankle-brachial index 0.4 0.7) who were revascularized with drug-eluting balloon from August 2011 to December 2014. Methods Three hundred and seven infrapopliteal arteries were revascularized only with drug-eluting balloon. Endpoints included target lesion revascularization, primary patency rate, and changes in ankle-brachial index and Rutherford class. Results Both ankle-brachial index improvement and Rutherford reduction were statistically significant (p < 0.001). At 36 months control, ankle brachial index improvement was 59.3% (p = 0.032). The clinically driven target lesion revascularization rate was 28% at 36 months. Limb salvage was accomplished in 73.6% of the critical limb ischemia cases, and complete wound healing was detected in 67.8% of cases with Rutherford category 5. Overall, the 1-year primary patency rate was 32.5%. Conclusions Drug-eluting balloons have shown successful performance in infrapopliteal arteries in mid-term, and evidence regarding clinical effectiveness and safety supports drug-eluting balloon angioplasty as the first line therapy in this segment. PMID- 29466935 TI - Endovascular approach in isolated abdominal aortic dissections. AB - Background Here, we report the mid-term results of endovascular treatment of isolated dissection of the abdominal aorta, which is a very rare pathology. Materials and methods A total of 11 patients (4 males (36.3%) and 7 females (63.6%)) aged 42-72 (mean, 60.3 +/- 10.45) years with isolated dissection of the abdominal aorta underwent endovascular stent-graft treatment at our institution between August 2010 and September 2015. Eight patients were symptomatic, and the remaining three were asymptomatic. The asymptomatic patients had aortic aneurysms coexisting with dissection. Eight patients without aneurysm had spontaneous dissections, and the most common symptom was unresponsive abdominal pain. Results The mean abdominal aorta diameter was 46.7 +/- 20.6 (range, 31.2-100.9) mm and the mean dissection length was 71.1 +/- 47.3 (range, 17-162) mm. Aorto-bi-iliac stent grafts were used in all patients, and were placed successfully under spinal anesthesia in all but one (90.9%) patient. Occlusion developed in one patient due to compression of the aorto-bi-iliac graft. Right-left femoral-femoral bypass was performed in this patient, who could not be placed on the opposite side. In addition, the graft was placed in one patient using the left renal artery chimney technique. No intraoperative mortality occurred, and open surgery was not required. In addition, no death occurred and no additional intervention was required during the mean follow-up period of 25.5 +/- 17.1 (range, 6-60) months. Conclusion Limited data regarding endovascular treatment of isolated dissection of the abdominal aorta are available in the literature. Based on data obtained in a limited number of patients, we consider endovascular aortic repair to be a good alternative to surgery due to its low morbidity and mortality rates. PMID- 29466936 TI - Utilization and in-hospital outcomes associated with atherectomy in the treatment of peripheral vascular disease: An observational analysis from the National Inpatient Sample. AB - Objective Percutaneous revascularization for patients with peripheral arterial disease has become a treatment of choice for many symptomatic patients. The presence of severe arterial calcification presents many challenges for successful revascularization. Atherectomy is an adjunctive treatment option for patients with severe calcification undergoing percutaneous intervention. We sought to analyze the impact of atherectomy on in-hospital outcomes, length of stay, and cost in the percutaneous treatment of peripheral arterial disease. Methods Patients with lower extremity peripheral arterial disease undergoing percutaneous revascularization were assessed, utilizing the National Inpatient Sample (2012 2014) and appropriate International Classification of Diseases, 9th Revision, Clinical Modification diagnostic and procedural codes. Patients who were not treated with atherectomy ( n = 51,037) were compared to those treated with atherectomy ( n = 11,408). Propensity score-matched analysis was performed to address baseline differences. Results After performing propensity score-matched analysis, 11,037 patients were included in each group. Utilization of atherectomy was associated with lower in-hospital mortality (2% vs. 1.4% p = 0.0006). All secondary outcomes were lower when using atherectomy except acute renal failure. Length of stay was slightly lower when using atherectomy (7.2 vs. 7.0 days, p = 0.0494). However, median cost was higher in patients treated with atherectomy ($21,589 vs. $24,060, p = <0.0001). Conclusion The use of atherectomy was associated with significantly decreased in-hospital mortality, adverse events, and length of stay. Though, cost associated with atherectomy use is increased, this is offset by decreased in-hospital adverse outcomes. Appropriate use of atherectomy devices is an important tool in revascularization of peripheral arterial disease in select patients.

PMID- 29466939 TI - Interatrial block and atrial remodeling assessed using speckle tracking echocardiography. AB - BACKGROUND: To evaluate the possibility of left atrial (LA) remodeling using speckle tracking echocardiography (STE) in patients with interatrial block (IAB). METHODS: We performed a cross-sectional study with three groups of patients: 56 without IAB, 21 with partial IAB (pIAB), and 22 with advanced IAB (aIAB). Transthoracic echocardiographic (TTE) STE was performed and clinical and echocardiographic findings were analyzed. RESULTS: TTE showed higher LA volume/body surface area in the patients with IAB. With STE, the absolute value of strain rate during atrial booster pump function (SRa) and early reservoir period (SRs) decreased in the pIAB group and even more in the aIAB group, compared to the group without IAB. The independent variables were the echocardiographic measures of LA size and function. After adjusting for confounders, both multiple linear regression and multivariate multinomial regression showed good correlation with dependent variables: longer P-wave duration on electrocardiography and with the type of IAB, respectively. SRa (p < 0.001), SRs (p < 0.001), and maximal peak LA longitudinal strain in the reservoir period (p = 0.009) were independently associated with P-wave duration. SRa was also associated with the presence of pIAB (OR = 11.5; 95% confidence interval (CI): 2.7-49.0; p = 0.001) and aIAB, (OR = 98.2; 95% CI: 16-120.4; p < 0.001) and SRs was associated with pIAB (OR: 0.03; CI: 0.003-0.29; p = 0.003) and with aIAB (OR: 0.008; CI: 0.001-0.12; p = 0.004). CONCLUSIONS: IAB correlates directly with structural remodeling and a decrease in the absolute value of LA SRa and SRs determined using STE. PMID- 29466940 TI - Analytical parameters and validation of homopolymer detection in a pyrosequencing based next generation sequencing system. AB - BACKGROUND: Current technologies in next-generation sequencing are offering high throughput reads at low costs, but still suffer from various sequencing errors. Although pyro- and ion semiconductor sequencing both have the advantage of delivering long and high quality reads, problems might occur when sequencing homopolymer-containing regions, since the repeating identical bases are going to incorporate during the same synthesis cycle, which leads to uncertainty in base calling. The aim of this study was to evaluate the analytical performance of a pyrosequencing-based next-generation sequencing system in detecting homopolymer sequences using homopolymer-preintegrated plasmid constructs and human DNA samples originating from patients with cystic fibrosis. RESULTS: In the plasmid system average correct genotyping was 95.8% in 4-mers, 87.4% in 5-mers and 72.1% in 6-mers. Despite the experienced low genotyping accuracy in 5- and 6-mers, it was possible to generate amplicons with more than a 90% adequate detection rate in every homopolymer tract. When homopolymers in the CFTR gene were sequenced average accuracy was 89.3%, but varied in a wide range (52.2 - 99.1%). In all but one case, an optimal amplicon-sequencing primer combination could be identified. In that single case (7A tract in exon 14 (c.2046_2052)), none of the tested primer sets produced the required analytical performance. CONCLUSIONS: Our results show that pyrosequencing is the most reliable in case of 4-mers and as homopolymer length gradually increases, accuracy deteriorates. With careful primer selection, the NGS system was able to correctly genotype all but one of the homopolymers in the CFTR gene. In conclusion, we configured a plasmid test system that can be used to assess genotyping accuracy of NGS devices and developed an accurate NGS assay for the molecular diagnosis of CF using self designed primers for amplification and sequencing. PMID- 29466941 TI - Transcription start site profiling uncovers divergent transcription and enhancer associated RNAs in Drosophila melanogaster. AB - BACKGROUND: High-resolution transcription start site (TSS) mapping in D. melanogaster embryos and cell lines has revealed a rich and detailed landscape of both cis- and trans-regulatory elements and factors. However, TSS profiling has not been investigated in an orthogonal in vivo setting. Here, we present a comprehensive dataset that links TSS dynamics with nucleosome occupancy and gene expression in the wandering third instar larva, a developmental stage characterized by large-scale shifts in transcriptional programs in preparation for metamorphosis. RESULTS: The data recapitulate major regulatory classes of TSSs, based on peak width, promoter-proximal polymerase pausing, and cis regulatory element density. We confirm the paucity of divergent transcription units in D. melanogaster, but also identify notable exceptions. Furthermore, we identify thousands of novel initiation events occurring at unannotated TSSs that can be classified into functional categories by their local density of histone modifications. Interestingly, a sub-class of these unannotated TSSs overlaps with functionally validated enhancer elements, consistent with a regulatory role for "enhancer RNAs" (eRNAs) in defining developmental transcription programs. CONCLUSIONS: High-depth TSS mapping is a powerful strategy for identifying and characterizing low-abundance and/or low-stability RNAs. Global analysis of transcription initiation patterns in a developing organism reveals a vast number of novel initiation events that identify potential eRNAs as well as other non coding transcripts critical for animal development. PMID- 29466942 TI - Identification of novel genes in the carotenogenic and oleaginous yeast Rhodotorula toruloides through genome-wide insertional mutagenesis. AB - BACKGROUND: Rhodotorula toruloides is an outstanding producer of lipids and carotenoids. Currently, information on the key metabolic pathways and their molecular basis of regulation remains scarce, severely limiting efforts to engineer it as an industrial host. RESULTS: We have adapted Agrobacterium tumefaciens-mediated transformation (ATMT) as a gene-tagging tool for the identification of novel genes in R. toruloides. Multiple factors affecting transformation efficiency in several species in the Pucciniomycotina subphylum were optimized. The Agrobacterium transfer DNA (T-DNA) showed predominantly single-copy chromosomal integrations in R. toruloides, which were trackable by high efficiency thermal asymmetric interlaced PCR (hiTAIL-PCR). To demonstrate the application of random T-DNA insertions for strain improvement and gene hunting, 3 T-DNA insertional libraries were screened against cerulenin, nile red and tetrazolium violet respectively, resulting in the identification of 22 mutants with obvious phenotypes in fatty acid or lipid metabolism. Similarly, 5 carotenoid biosynthetic mutants were obtained through visual screening of the transformants. To further validate the gene tagging strategy, one of the carotenoid production mutants, RAM5, was analyzed in detail. The mutant had a T DNA inserted at the putative phytoene desaturase gene CAR1. Deletion of CAR1 by homologous recombination led to a phenotype similar to RAM5 and it could be genetically complemented by re-introduction of the wild-type CAR1 genome sequence. CONCLUSIONS: T-DNA insertional mutagenesis is an efficient forward genetic tool for gene discovery in R. toruloides and related oleaginous yeast species. It is also valuable for metabolic engineering in these hosts. Further analysis of the 27 mutants identified in this study should augment our knowledge of the lipid and carotenoid biosynthesis, which may be exploited for oil and isoprenoid metabolic engineering.

PMID- 29466944 TI - Risk variants of the alpha-synuclein locus and REM sleep behavior disorder in Parkinson's disease: a genetic association study. AB - BACKGROUND: Parkinson's disease is a heterogeneous disorder where genetic factors may underlie clinical variability. Rapid eye movement sleep behavior disorder (RBD) is a parasomnia strongly linked to synucleinopathies, including Parkinson's disease. We hypothesized that SNCA variants conferring risk of Parkinson's disease would also predispose to an RBD phenotype. METHODS: We assessed possible RBD (pRBD) status using the RBD screening questionnaire and investigated known susceptibility variants for Parkinson's disease located in the alpha-synuclein (SNCA) and tau (MAPT) gene loci in 325 Parkinson's disease patients. Associations between genetic risk variants and RBD were investigated by logistic regression, and an independent dataset of 382 patients from the Parkinson's Progression Marker Initiative (PPMI) study was used for replication. RESULTS: pRBD was associated with rs3756063 located in the 5' region of SNCA (two-sided p = 0.018, odds ratio 1.44). We replicated this finding in the PPMI dataset (one-sided p = 0.036, odds ratio 1.35) and meta-analyzed the results (two-sided p = 0.0032, odds ratio 1.40). The Parkinson's disease risk variant in the 3' region of SNCA and the MAPT variant showed no association with pRBD. CONCLUSIONS: Our findings provide proof of principle that a largely stable, dichotomous clinical feature of Parkinson's disease can be linked to a specific genetic susceptibility profile. Indirectly, it also supports the hypothesis of RBD as relevant marker for a distinct subtype of the disorder. PMID- 29466945 TI - Diversity and evolution of the repetitive genomic content in Cannabis sativa. AB - BACKGROUND: The repetitive content of the genome, once considered to be "junk DNA", is in fact an essential component of genomic architecture and evolution. In this study, we used the genomes of three varieties of Cannabis sativa, three varieties of Humulus lupulus and one genotype of Morus notabilis to explore their repetitive content using a graph-based clustering method, designed to explore and compare repeat content in genomes that have not been fully assembled. RESULTS: The repetitive content in the C. sativa genome is mainly composed of the retrotransposons LTR/Copia and LTR/Gypsy (14% and 14.8%, respectively), ribosomal DNA (2%), and low-complexity sequences (29%). We observed a recent copy number expansion in some transposable element families. Simple repeats and low complexity regions of the genome show higher intra and inter species variation. CONCLUSIONS: As with other sequenced genomes, the repetitive content of C. sativa's genome exhibits a wide range of evolutionary patterns. Some repeat types have patterns of diversity consistent with expansions followed by losses in copy number, while others may have expanded more slowly and reached a steady state. Still, other repetitive sequences, particularly ribosomal DNA (rDNA), show signs of concerted evolution playing a major role in homogenizing sequence variation. PMID- 29466946 TI - Performance of loop-mediated isothermal amplification assay in the diagnosis of pulmonary tuberculosis in a high prevalence TB/HIV rural setting in Uganda. AB - BACKGROUND: Smear microscopy lacks sensitivity especially in HIV co-infection, resulting in undiagnosed tuberculosis (TB) and high mortality. The loop-mediated isothermal amplification (TB-LAMP) assay can be staged with minimal infrastructure, is rapid, low cost and detection can be with the naked eye. We assessed feasibility and performance of Eiken TB-LAMP test at point-of-need in TB diagnosis in a high prevalence TB/HIV rural setting in Uganda. METHODS: From October 2013-February 2014, TB-LAMP testing was performed on sputum specimens from outpatient presumptive TB adults at a district hospital and two low-level health centers in Kiboga District where smear microscopy is the available routine diagnostic option. TB-LAMP was performed by a technician after a week of training in the district hospital. The technician had no prior experience in the technology. Samples from the low-level health centers were transported to the district hospital for TB-LAMP. RESULTS: Of the 233 presumptive TB (126 at hospital); 113 (48.5%) were HIV-infected; 129 (55%) male; median age 40 (IQR 30 53). Compared to MTB culture, overall sensitivity and specificity of TB-LAMP were 55.4% (95 CI 44.1-66.3) and 98.0% (95 CI 94.3-99.6) respectively. Among HIV infected participants, TB-LAMP sensitivity and specificity were 52.3% (95 CI 36.7 67.5%) and 97.1% (95 CI 89.9-99.6) respectively; and 24.4% (95% CI 12.9-39.5) and 98.6% (95% CI 95.1-99.8) respectively among smear-negatives. TB-LAMP sensitivity and specificity were 62.2% (95% CI 44.8-77.5) and 97.8% (95% CI 92.1-99.7) in the hospital setting where central testing occurred compared to 50.0% (95% CI 34.9 65.1) and 98.4% (95% CI 91.2-100) respectively in low-level health centers where specimens were transported centrally. CONCLUSIONS: In this high prevalence TB/HIV rural setting, TB-LAMP performs better than conventional smear microscopy in diagnosis of MTB among presumptive TB patients although the sensitivity is lower than that reported by the World Health Organization. TB-LAMP can easily be performed following a short training period and in absence of sophisticated infrastructure and expertise. PMID- 29466947 TI - Stroke as an atypical initial presentation of giant cell arteritis. AB - BACKGROUND: Giant cell arteritis (GCA) is an immune mediated inflammatory disease of medium and large arteries which afflicts older people. The classical presentation features include: headache, visual disturbances, and jaw claudication. Patients diagnosed with GCA have also been observed to be at higher risk for the subsequent development of strokes. CASE PRESENTATION: We describe a case of an 84-year old right-handed man who presented to hospital with dysarthria, dysphagia, right-sided facial drop, a history of generalized weakness and multiple falls. He was admitted to geriatric medicine with the working diagnosis of a posterior circulation stroke syndrome. He was also started on antibiotic treatment for a possible community-acquired pneumonia because of the presence of a low-grade fever and a chest radiograph showing ill-defined left lower lobe airspace disease. Initial lab results were remarkable for an erythrocyte sedimentation rate (ESR) of 112 mm/h and a C-reactive protein (CRP) level of 110 mg/L consistent with an active inflammatory state. Neurovascular imaging showed mild atherosclerotic changes of the aortic arch and proximal great vessels without significant stenosis. The patient was started on daily high-dose prednisone because of the possibility of a cerebral vasculitis. Bilateral biopsy of temporal arteries showed giant cell arteritis. The patient's neurologic status and inflammatory markers significantly improved (ESR 52 mm/h, CRP 7.0 mg/L) and he was eventually discharged to a seniors home with services. CONCLUSION: The initial presentation of giant cell arteritis as a stroke syndrome, especially in the posterior circulation territory, is exceedingly rare. Other atypical presenting symptoms may include chronic cough and fever of unknown origin. The elevated ESR and CRP levels were clues to the diagnosis and clinical decision making should be driven by a high index of suspicion since no single test (ESR, CRP, temporal artery biopsy) has perfect sensitivity. Elevated CRP may have a role in increasing stroke risk. This case report illustrates that in older people clinicians must consider atypical presentations of disease more often since timely diagnosis and initiation of treatment can result in optimal outcomes. PMID- 29466948 TI - High inter-observer agreement of observer-perceived pain assessment in the emergency department. AB - BACKGROUND: Triage is used to prioritize the patients in the emergency department. The majority of the triage systems include the patients' pain score to assess their level of acuity by using a combination of patient reported pain and observer-perceived pain; the latter therefore requires a certain degree of inter-observer agreement. The aim of the present study was to assess the inter observer agreement of perceived pain among emergency department nurses and to evaluate if it was influenced by predetermined factors like age and gender. METHOD: A project assistant randomly recruited two nurses, who were not allowed to interact with each other, to assess patient pain intensity on the numeric ranking scale. The project assistant afterwards entered the pain scores in a predesigned electronic questionnaire. We used weighted Fleiss-Cohen (quadratic) kappa statistics, Bland-Altman statistics and logistic regression analysis to assess the inter-observer agreement. RESULTS: One hundred and sixty-two patients were included. They had a median age of 38 years and 45% were females. 30% of the patients were acute surgical patients and 70% acute orthopedic patients. The average time between the pain assessments were 1,7 min. The Bland Altman analysis found a mean difference in pain score of 0.2 and 95% limits of agreement of +/- 3 point. When the NRS scores were translated to commonly used pain categories (no, mild, moderate or severe pain) we found a 70% agreement with a mean difference in categories of 0.05 and 95% limits of agreement of +/- 1 category. Patient age, gender, localization of pain, examination room or presence of a significant other did not affect the inter-observer agreement. CONCLUSION: We found 70% agreement on pain category between the nurses and it is justified that nurse-perceived pain assessment is used for triage in the emergency department. PMID- 29466949 TI - The association between pre pregnancy body mass index and risk of preeclampsia: a registry based study from Tanzania. AB - BACKGROUND: Preeclampsia is among the leading causes of maternal mortality and morbidity worldwide, occurs in 2-8% of all pregnancies, and is estimated to account for at least 9 % of maternal deaths in Africa. Studies from developed countries show that high pre pregnancy body mass index (BMI) increases the risk of preeclampsia. We examined the association between pre pregnancy BMI and the risk of preeclampsia in Tanzania, a low income country. METHODS: Data from the Kilimanjaro Christian Medical Center (KCMC) Medical Birth Registry recorded between July 2000 and May 2013 were used. We restricted the study population to singleton deliveries among women with no or one previous pregnancy. Pre pregnancy BMI (kg/m2) was categorized according to the WHO categories of underweight (less than 18.5), normal (18.5 - 24.9), overweight (25.0 - 29.9) and obese (30 or more). Potential confounders were adjusted for in multivariable analyses. RESULTS: Among the 17,738 singleton births, 6.6% of the mothers were underweight, 62.1% were of normal BMI, 24.0% were overweight, and 7.3% were obese. Five hundred and eighty-two pregnancies (3.3%) were affected by preeclampsia. Compared to those with normal BMI, overweight and obese women had a higher risk of preeclampsia (aOR (95% CI) 1.4 (1.2 - 1.8) and 1.8 (1.3 - 2.4)), respectively, while underweight women had a lower risk (0.7 (0.4-1.1)). CONCLUSIONS: Pre pregnancy maternal overweight and obesity were associated with an increased risk of preeclampsia in Tanzania. Risks were similar to those reported in high income countries. PMID- 29466950 TI - HPV positive, wild type TP53, and p16 overexpression correlate with the absence of residual tumors after chemoradiotherapy in anal squamous cell carcinoma. AB - BACKGROUND: Anal residual tumors are consensually identified within six months of chemoradiotherapy and represent a persistent lesion that may have prognostic value for overall survival. The aim of this study was to evaluate the association of HPV and HIV status, p16 expression level and TP53 mutations with the absence of residual tumors (local response) in Squamous Cell Carcinoma (SCC) of the anal canal after chemoradiotherapy. METHODS: We performed a study on 78 patients with SCC of the anal canal who submitted to chemoradiotherapy and were followed for a six-month period to identify the absence or presence of residual tumors. HPV DNA was identified by polymerase chain reaction and direct sequencing, HIV RNA was detected by TaqMan amplification, p16 expression was detected by western blotting, and the mutational analysis of TP53 was performed by direct sequencing; additionally, samples carrying mutations underwent fluorescent in sit hybridization. The evaluation of the tumor response to treatment was conducted six months after the conclusion of chemoradiotherapy. The following classifications were used to evaluate the outcomes: a) no response (presence of residual tumor) and b) complete response (absence of residual tumor). RESULTS: The significant variables associated with the absence of residual tumors were HPV positive, p16 overexpressed, wild-type TP53, female gender, and stages I and II. Only the presence of HPV was independently correlated with the clinical response; this variable increased the chances of a response within six months by 31-fold. CONCLUSIONS: The presence of HPV in tumor cells was correlated with the absence of a residual tumor. This correlation is valuable and can direct future therapeutic approaches in the anal canal. PMID- 29466952 TI - Socio-economic, Knowledge Attitude Practices (KAP), household related and demographic based appearance of non-dengue infected individuals in high dengue risk areas of Kandy District, Sri Lanka. AB - BACKGROUND: Socio-economic, demographic factors and Knowledge Attitude Practices (KAPs) have been recognized as critical factors that influence the incidence and transmission of dengue epidemics. However, studies that characterize above features of a risk free or low risk population are rare. Therefore, the present study was conducted to characterize the household related, demographic, socio economic factors and KAPs status of five selected dengue free communities. METHOD: An analytical cross-sectional survey was conducted on selected demographic, socio-economic, household related and KAPs in five selected dengue free communities living in dengue risk areas within Kandy District, Central Province, Sri Lanka. Household heads of 1000 randomly selected houses were interviewed in this study. Chi-square test for independence, cluster analysis and Principal Coordinates (PCO) analysis were used for data analysis. RESULTS: Knowledge and awareness regarding dengue, (prevention of the vector breeding, bites of mosquitoes, disease symptoms and waste management) and attitudes of the community (towards home gardening, composting, waste management and maintenance of a clean and dengue free environment) are associated with the dengue free status of the study populations. CONCLUSIONS: The vector controlling authorities should focus on socio-economic, demographic and KAPs in stimulating the community to cooperate in the integrated vector management strategies to improve vector control and reduce transmission of dengue within Kandy District. PMID- 29466951 TI - A methodology review on the incremental prognostic value of computed tomography biomarkers in addition to Framingham risk score in predicting cardiovascular disease: the use of association, discrimination and reclassification. AB - BACKGROUND: Computed tomography (CT) biomarkers claim to improve cardiovascular risk stratification. This review focuses on significant differences in incremental measures between adequate and inadequate reporting practise. METHODS: Studies included were those that used Framingham Risk Score as a baseline and described the incremental value of adding calcium score or CT coronary angiogram in predicting cardiovascular risk. Searches of MEDLINE, EMBASE, Web of Science and Cochrane Central were performed with no language restriction. RESULTS: Thirty five studies consisting of 206,663 patients (men = 118,114, 55.1%) were included. The baseline Framingham Risk Score included the 1998, 2002 and 2008 iterations. Selective reporting, inconsistent reference groupings and thresholds were found. Twelve studies (34.3%) had major and 23 (65.7%) had minor alterations and the respective Delta AUC were significantly different (p = 0.015). When the baseline model performed well, the Delta AUC was relatively lower with the addition of a CT biomarker (Spearman coefficient = - 0.46, p < 0.0001; n = 33; 76 pairs of data). Other factors that influenced AUC performance included exploration of data analysis, calibration, validation, multivariable and AUC documentation (all p < 0.05). Most studies (68.7%) that reported categorical NRI (n = 16; 46 pairs of data) subjectively drew strong conclusions along with other poor reporting practices. However, no significant difference in values of NRI was found between adequate and inadequate reporting. CONCLUSIONS: The widespread practice of poor reporting particularly association, discrimination, reclassification, calibration and validation undermines the claimed incremental value of CT biomarkers over the Framingham Risk Score alone. Inadequate reporting of discrimination inflates effect estimate, however, that is not necessarily the case for reclassification. PMID- 29466953 TI - The association between community-associated Staphylococcus aureus colonization and disease: a meta-analysis. AB - BACKGROUND: Colonization with Staphylococcus aureus is a well-defined risk factor for disease in hospitals, which can range from minor skin infections to severe, systemic diseases. However, the generalizability of this finding has not been thoroughly investigated outside of the hospital environment. We aimed to assess the role of S. aureus colonization as a risk factor for disease in the community. METHODS: We performed a meta-analysis of observational studies and searched PubMed for articles published between December 1979 and May 23, 2016. We included cohort, cross-sectional, and case-control studies that reported quantitative estimates of both S. aureus colonization and disease statuses of all study subjects. We excluded studies on recently hospitalized subjects, long-term care facilities, surgery patients, dialysis patients, hospital staff, S. aureus outbreaks, and livestock-associated infections. Our meta-analysis was performed using random-effects analysis to obtain pooled odds ratios (ORs) to compare the odds of S. aureus disease with respect to S. aureus colonization status. RESULTS: We identified 3477 citations, of which 12 articles on 6998 subjects met the eligibility criteria. Overall, subjects colonized with S. aureus were more likely to progress to disease than those who were non-colonized: (OR 1.87, 95% CI 1.21 2.88, n = 7 studies). We observed a larger effect with methicillin-resistant S. aureus colonization (7.06, 4.60-10.84, n = 7 studies). However, the methicillin sensitive S. aureus colonization was not associated with greater odds of disease (1.20, 0.69-2.06, n = 4 studies). Heterogeneity was present across studies in all of the subgroups: S. aureus (I2 = 95.0%, chi2 = 120.3, p < 0.001), MRSA (I2 = 92.8%, chi2 = 82.8, p = p < 0.001), and MSSA (I2 = 86.3%, chi2 = 21.8, p < 0.001). CONCLUSIONS: While the majority of papers individually support the assumption that colonization is a risk factor for S. aureus disease in the general population, there is marked heterogeneity between studies and further investigation is needed to identify the major sources of this variance. There is a shortage of literature addressing this topic in the community setting and a need for further research on colonization as a focus for disease prevention. PMID- 29466954 TI - Cognitive function and the agreement between self-reported and accelerometer accessed physical activity. AB - BACKGROUND: Numerous studies have reported weak or moderate correlations between self-reported and accelerometer-assessed physical activity. One explanation is that self-reported physical activity might be biased by demographic, cognitive or other factors. Cognitive function is one factor that could be associated with either overreporting or underreporting of daily physical activity. Difficulties in remembering past physical activities might result in recall bias. Thus, the current study examines whether the cognitive function is associated with differences between self-reported and accelerometer-assessed physical activity. METHODS: Cross-sectional data from the population-based Activity and Function in the Elderly in Ulm study (ActiFE) were used. A total of 1172 community-dwelling older adults (aged 65-90 years) wore a uniaxial accelerometer (activPAL unit) for a week. Additionally, self-reported physical activity was assessed using the LASA Physical Activity Questionnaire (LAPAQ). Cognitive function was measured with four items (immediate memory, delayed memory, recognition memory, and semantic fluency) from the Consortium to Establish a Registry for Alzheimer's Disease Total Score (CERAD-TS). RESULTS: Mean differences of self-reported and accelerometer-assessed physical activity (MPA) were associated with cognitive function in men (rs = -.12, p = .002) but not in women. Sex-stratified multiple linear regression analyses showed that MPA declined with high cognitive function in men (beta = -.13; p = .015). CONCLUSION: Results suggest that self-reported physical activity should be interpreted with caution in older populations, as cognitive function was one factor that explained the differences between objective and subjective physical activity measurements.

PMID- 29466956 TI - Outcome and prognostic factors of patients with right-sided infective endocarditis requiring intensive care unit admission. AB - BACKGROUND: Right-sided infective endocarditis (RSIE) is an uncommon diagnosis accounting for less than 10% of cases of infective endocarditis. Optimal management for severely ill patients with RSIE remains challenging because few studies reported on management and outcome. The goal of our study was to determine outcome and associated prognostic factors in a population of ICU patients with a diagnosis of definite, active and severe RSIE. METHODS: We performed a retrospective study in 10 French ICUs between January 2002 and December 2012. Main outcome was mortality at 30 days after ICU admission. Significant variables associated with 30-days mortality in the bivariate analysis were included in a logistic regression analysis. RESULTS: A total of 37 patients were studied. Mean age was 47.9 +/- 18.4 years. Mean SAPS II, SOFA score and Charlson comorbidity index were 32.4 +/- 17.4, 6.3 +/- 4.4 and 3.1 +/- 3.4, respectively. Causative pathogens, identified in 34 patients, were mainly staphylococci (n = 29). The source of endocarditis was a catheter related infection in 10 patients, intravenous drug abuse in 8 patients, cutaneous in 7 patients, urinary tract related in one patient and has an unknown origin in 7 patients. Vegetation size was higher than 20 mm for 14 patients. Valve tricuspid regurgitation was classified as severe in 11 patients. All patients received initial appropriate antimicrobial therapy. Aminoglycosides were delivered in combination with beta-lactam antibiotics or vancomycin in 22 patients. Surgical procedure was performed in 14 patients. Eight patients (21.6%) died within 30 days following ICU admission. One independent prognostic factor was identified: use of aminoglycosides was associated with improved outcome (OR = 0.1; 95%CI = 0.0017-0.650; p = 0.007). CONCLUSION: Mortality of patients with RSIE needing ICU admission is high. Aminoglycosides used in combination with beta-lactam or vancomycin could reduce 30 days mortality. PMID- 29466957 TI - Altered DNA methylation in liver and adipose tissues derived from individuals with obesity and type 2 diabetes. AB - BACKGROUND: Obesity is a well-recognized risk factor for insulin resistance and type 2 diabetes (T2D), although the precise mechanisms underlying the relationship remain unknown. In this study we identified alterations of DNA methylation influencing T2D pathogenesis, in subcutaneous and visceral adipose tissues, liver, and blood from individuals with obesity. METHODS: The study included individuals with obesity, with and without T2D. From these patients, we obtained samples of liver tissue (n = 16), visceral and subcutaneous adipose tissues (n = 30), and peripheral blood (n = 38). We analyzed DNA methylation using Illumina Infinium Human Methylation arrays, and gene expression profiles using HumanHT-12 Expression BeadChip Arrays. RESULTS: Analysis of DNA methylation profiles revealed several loci with differential methylation between individuals with and without T2D, in all tissues. Aberrant DNA methylation was mainly found in the liver and visceral adipose tissue. Gene ontology analysis of genes with altered DNA methylation revealed enriched terms related to glucose metabolism, lipid metabolism, cell cycle regulation, and response to wounding. An inverse correlation between altered methylation and gene expression in the four tissues was found in a subset of genes, which were related to insulin resistance, adipogenesis, fat storage, and inflammation. CONCLUSIONS: Our present findings provide additional evidence that aberrant DNA methylation may be a relevant mechanism involved in T2D pathogenesis among individuals with obesity. PMID- 29466958 TI - Case presentation: implantation of cardiac resynchronization therapy pacemaker via the coronary sinus in a patient with triple valve replacement. AB - BACKGROUND: In patients with triple valve replacement developing third-degree atrioventricular block (AVB), the most appropriate approach for permanent pacemaker implantation remains questionable. CASE PRESENTATION: In this case presentation, we first described the approach of implantation of the cardiac resynchronization therapy pacemaker (CRT-P) via one bipolar pacing lead in middle cardiac vein (MCV) and one quadripolar pacing lead in anterior interventricular vein (AIV) in a patient developing complete AVB, who had been previously diagnosed with rheumatic valvular heart disease with triple valve replaced. After the CRT-P implantation, the two pacing leads in coronary sinus (CS) provided a dual-site ventricular pacing from the anterior septum and posterior septum, which resulted in a narrow QRS complex and an increased ventricular synchrony. During the long-term follow-up, no deterioration of heart function was documented and pacing parameters remained good. CONCLUSION: In this patient developing complete AVB with triple valve replaced, our approach of CRT-P implantation provides an effective and reliable ventricular pacing, and is an alternative option when transvenous right ventricular pacing, transseptal left ventricular pacing and transpericardial epicardium pacing are not possible. Further prospective randomized trials are required to confirm the efficiency of our approach of dual site ventricular pacing by CRT-P in this kind patients. PMID- 29466959 TI - "Self-development matters" - Perception of Sakhis (CHWs) assessing self development outcomes of their participation in the HBNC Program. AB - BACKGROUND: Community Health Workers (CHWs) play an instrumental role in promoting socio-behavioural change at the community level, which results in changed indicators of community health. While outcomes are mostly reviewed for achieving program objectives, it is pertinent to understand the process of program implementation mainly from the perception of participating CHWs. METHODS: A qualitative study to understand the perception of Sakhi's (CHWs) regarding the outcomes of their participation in Home-Based Neonatal Care (HBNC) Program implemented by a non-governmental organization (NGO). Data consisted of 3 FGDs and 20 in-depth unstructured interviews with participating Sakhis. RESULTS: Sakhis perceived their ability to take decisions at critical phases of the program as an important factor influencing their performance. The opportunity to participate as a Sakhi in the health programme initiated a process of change at the personal level. The changes perceived by Sakhis were enhancement in knowledge, skills and capabilities of Sakhis. The combination of improved skills, knowledge and attitude had culminated in the process of experiencing self empowerment for the participating Sakhis. Their ability to positively influence the individuals and community with their initiatives to improve women and child health and save lives in critical situations facilitated development of a new identity and improved societal status in their communities. Changed power relations at the family and community level promoted the involvement of Sakhis in the broader development agenda. Sakhis' ability to strategize goals, evaluate their own abilities, their willingness to upgrade knowledge and take others along in bringing social change, was an evident movement towards self-development. CONCLUSION: An opportunity for local women to participate in development programs creates potential for self-development as a cascading effect in addition to the accomplishment of planned program objective. PMID- 29466960 TI - High-dose of intravenous immunoglobulin modulates immune tolerance in premature infants. AB - BACKGROUND: Intravenous immunoglobulin (IVIG) is commonly used to improve the immunomodulatory effects, although its regulatory effect on premature Treg cells is unclear. The purpose of this study is to study the effect of high dose of IVIG (HD-IVIG) on Treg cells expression and cytokine profile in premature birth. METHODS: Fifty-two premature infants were enrolled in this study and thirty-one premature infants who were suspected to have intrauterine infection received HD IVIG (1-2 g/kg) at the first day of birth; the remaining 21 premature infants were assigned as the control group. The peripheral blood CD4 + T and foxp3+ Treg cells were checked by flow cytometry, and cytokine concentrations were detected by cytometric bead array. RESULTS: With the gestational age growth, peripheral blood CD4 + T and foxp3+ Treg cells of prematurity gradually declined from 50% to 35% and from 8% to 6%, respectively. Meanwhile, HD-IVIG increased the percentage of CD4 + T and foxp3+ Treg cells compared with their baseline levels (p < 0.001). HD-IVIG demonstrated different regulating effects on cytokines secretion, increased IL-17 and TGF-beta, and inhibited IL-6 secretion. CONCLUSION: Our results demonstrated that HD-IVIG not only enhanced the premature immune tolerance, but also suppressed the excessive inflammation response mediated by IL 6. TRIAL REGISTRATION: This study was under the clinical study registration (ChiCTR-ORC-16008872, date of registration, 2016-07-21). PMID- 29466961 TI - A randomised trial to compare cognitive outcome after gamma knife radiosurgery versus whole brain radiation therapy in patients with multiple brain metastases: research protocol CAR-study B. AB - BACKGROUND: Gamma Knife radiosurgery (GKRS) is increasingly applied in patients with multiple brain metastases and is expected to have less adverse effects in cognitive functioning than whole brain radiation therapy (WBRT). Effective treatment with the least negative cognitive side effects is increasingly becoming important, as more patients with brain metastases live longer due to more and better systemic treatment options. There are no published randomized trials yet directly comparing GKRS to WBRT in patients with multiple brain metastases that include objective neuropsychological testing. METHODS: CAR-Study B is a prospective randomised trial comparing cognitive outcome after GKRS or WBRT in adult patients with 11-20 newly diagnosed brain metastases on a contrast-enhanced MRI-scan, KPS >=70 and life expectancy of at least 3 months. Randomisation by the method of minimization, is stratified by the cumulative tumour volume in the brain, systemic treatment, KPS, histology, baseline cognitive functioning and age. The primary endpoint is the between-group difference in the percentage of patients with significant memory decline at 3 months. Secondary endpoints include overall survival, local control, development of new brain metastases, cognitive functioning over time, quality of life, depression, anxiety and fatigue. Cognitive functioning is assessed by a standardised neuropsychological test battery. Assessments (cognitive testing, questionnaires and MRI-scans) are scheduled at baseline and at 3, 6, 9, 12 and 15 months after treatment. DISCUSSION: Knowledge gained from this trial may be used to inform individual patients with BM more precisely about the cognitive effects they can expect from treatment, and to assist both doctors and patients in making (shared) individual treatment decisions. This trial is currently recruiting. Target accrual: 23 patients at 3-months follow-up in both groups. TRIAL REGISTRATION: The Netherlands Trials Register number NTR5463. ClinicalTrials.gov registration number NCT02953717 , first received October 27, 2016, 8 patients were enrolled in this study on 31 July 2017. PMID- 29466962 TI - The long non-coding RNA MYCNOS-01 regulates MYCN protein levels and affects growth of MYCN-amplified rhabdomyosarcoma and neuroblastoma cells. AB - BACKGROUND: MYCN is amplified in small cell lung cancers and several pediatric tumors, including alveolar rhabdomyosarcomas and neuroblastomas. MYCN protein is known to play a key oncogenic role in both alveolar rhabdomyosarcomas and neuroblastomas. MYCN opposite strand (MYCNOS) is a gene located on the antisense strand to MYCN that encodes alternatively spliced transcripts, two of which (MYCNOS-01 and MYCNOS-02) are known to be expressed in neuroblastoma and small cell lung cancer with reciprocal regulation between MYCNOS-02 and MYCN reported for neuroblastomas. We sought to determine a functional role for MYCNOS-01 in alveolar rhabdomyosarcoma and neuroblastoma cells and identify any associated regulatory effects between MYCN and MYCNOS-01. METHODS: MYCNOS-01, MYCNOS-02 and MYCN expression levels were assessed in alveolar rhabdomyosarcoma and neuroblastoma cell lines and tumor samples from patients using Affymetrix microarray data and quantitative RT-PCR. Following MYCNOS-01 or MYCN siRNA knockdown and MYCNOS-01 overexpression, transcript levels were assayed by quantitative RT-PCR and MYCN protein expression assessed by Western blot and immunofluorescence. Additionally, effects on cell growth, apoptosis and cell cycle profiles were determined by a metabolic assay, caspase activity and flow cytometry, respectively. RESULTS: MYCNOS-01 transcript levels were generally higher in NB and RMS tumor samples and cell lines with MYCN genomic amplification. RNA interference of MYCNOS-01 expression did not alter MYCN transcript levels but decreased MYCN protein levels. Conversely, MYCN reduction increased MYCNOS-01 transcript levels, creating a negative feedback loop on MYCN protein levels. Reduction of MYCNOS-01 or MYCN expression decreased cell growth in MYCN-amplified alveolar rhabdomyosarcoma and neuroblastoma cell lines. This is consistent with MYCNOS-01-mediated regulation of MYCN contributing to the phenotype observed. CONCLUSIONS: An alternative transcript of MYCNOS, MYCNOS-01, post-transcriptionally regulates MYCN levels and affects growth in MYCN-amplified rhabdomyosarcoma and neuroblastoma cells. PMID- 29466963 TI - Pediatric severe asthma: a case series report and perspectives on anti-IgE treatment. AB - BACKGROUND: The primary goal of asthma management is to achieve disease control for reducing the risk of future exacerbations and progressive loss of lung function. Asthma not responding to treatment may result in significant morbidity. In many children with uncontrolled symptoms, the diagnosis of asthma may be wrong or adherence to treatment may be poor. It is then crucial to distinguish these cases from the truly "severe therapy-resistant" asthmatics by a proper filtering process. Herein we report on four cases diagnosed as difficult asthma, detail the workup that resulted in the ultimate diagnosis, and provide the process that led to the prescription of omalizumab. CASE PRESENTATION: All children had been initially referred because of asthma not responding to long-term treatment with high-dose inhaled steroids, long-acting beta2-agonists and leukotriene receptor antagonists. Definitive diagnosis was severe asthma. Three out four patients were treated with omalizumab, which improved asthma control and patients' quality of life. We reviewed the current literature on the diagnostic approach to the disease and on the comorbidities associated with difficult asthma and presented the perspectives on omalizumab treatment in children and adolescents. Based on the evidence from the literature review, we also proposed an algorithm for the diagnosis of pediatric difficult-to-treat and severe asthma. CONCLUSIONS: The management of asthma is becoming much more patient-specific, as more and more is learned about the biology behind the development and progression of asthma. The addition of omalizumab, the first targeted biological treatment approved for asthma, has led to renewed optimism in the management of children and adolescents with atopic severe asthma. PMID- 29466964 TI - Successful treatment with pazopanib plus PD-1 inhibitor and RAK cells for advanced primary hepatic angiosarcoma: a case report. AB - BACKGROUND: Primary hepatic angiosarcoma (PHA) is a rare and aggressive solid tumor, with high rates of local recurrence and distant metastasis, and poor prognosis. There are no established treatment guidelines for PHA. CASE PRESENTATION: A 78-year-old asymptomatic man with PHA that was successfully treated with pazopanib plus PD-1 inhibitor and RetroNectin-activated killer cells (RAK cells). After one month of treatment, there was a clear reduction in the size and number of the liver metastases; and after nearly 15 months, most of the lesions were stable, no new lesions had developed, and the side effect of treatment was minor. CONCLUSION: Pazopanib, PD-1 inhibitor and RAK cells could serve as a potential option for the treatment of advanced PHA. PMID- 29466965 TI - Neutropenia after intravenous immunoglobulin therapy is associated with coronary artery lesions in children with Kawasaki disease: a case control study. AB - BACKGROUND: To evaluate differences in laboratory parameters, clinical presentation, and incidence of coronary artery lesions (CAL) between children with neutropenic and non-neutropenic Kawasaki disease (KD). METHODS: All consecutive KD patients that presented to the Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University in Wenzhou, China between January 2005 and December 2015 were included in this study. Patients were divided into two groups (KD with neutropenia (NKD) and KD without neutropenia (NNKD)) based on whether or not they developed neutropenia during the course of treatment. We compared differences in clinical manifestations, laboratory parameters, and treatment protocols between groups. We also evaluated the relationship between neutropenia with immunoglobulin dosage and incidence of CAL. RESULTS: An IVIG treatment regimen of 2 g/kg*1d was associated with a lower incidence of neutropenia compared to the 1 g/kg*2d protocol. The incidence of CAL was higher in KD patients with neutropenia than in those without. Subgroup analysis showed no difference in the incidence of CAL among the different age groups between KD patients with and without neutropenia. CONCLUSIONS: Follow up ultrasonic echocardiography should be performed in KD patients with neutropenia in order to allow for early detection of CAL and timely intervention. PMID- 29466966 TI - Real life patterns of care and progression free survival in metastatic renal cell carcinoma patients: retrospective analysis of cross-sectional data. AB - BACKGROUND: Patient characteristics and survival outcomes in randomized trials may be different from those in real-life clinical practice. The objective of this study was to describe treatment pathways, safety, drug costs and survival in patients with metastatic Renal Cell Carcinoma (mRCC) in a real world setting. METHODS: A retrospective analysis was performed using IQVIA real world oncology cross-sectional survey data, a retrospective treatment database collecting anonymized patient-level data in Europe. Data on treatment naive patients with mRCC who received a first-line targeted therapy in France were extracted for the period 2005-2015. Descriptive analyses were performed on treatment patterns, patient characteristics and safety profiles. Progression Free Survival (PFS) was determined using Kaplan-Meier survival analysis. RESULTS: One thousand three hundred thirty-one patients with mRCC who received a first-line targeted therapy were included. The male/female sex ratio was 2.5 and 66% of patients were aged > 60 years. 83% of patients had clear cell adenocarcinoma. 83% of patients underwent a surgical procedure, 10% had radiotherapy. In patients who received a first-line targeted therapy, 73% received sunitinib. The mean time from diagnosis to first-line treatment by targeted therapies in patients initially diagnosed with metastatic disease was 3.3 months [95% CI:2.5-4.1]. In patients who received second-line targeted therapy n = 257 (19%), the most frequently observed treatment sequences were sunitinib-everolimus (33%) and sunitinib-sorafenib (27%). Adverse events data were available for 501 patients and adverse events were documented in 70% of patients, most frequently diarrhoea. The overall median PFS was 13 months [95% CI:11.5-16]. CONCLUSION: Patient characteristics were consistent with the literature. Treatment patterns appeared to follow current practice guidelines. Despite some variations, PFS in our study seems to be consistent with findings from other real world studies. Nevertheless, PFS results were higher than those observed in clinical trials. Due to the use of cross sectional data, PFS in our study should be interpreted with caution. PMID- 29466967 TI - A pediatric death audit in a large referral hospital in Malawi. AB - BACKGROUND: Death audits have been used to describe pediatric mortality in under resourced settings, where record keeping is often a challenge. This information provides the cornerstone for the foundation of quality improvement initiatives. Malawi, located in sub-Saharan Africa, currently has an Under-5 mortality rate of 64/1000. Kamuzu Central Hospital, in the capital city Lilongwe, is a busy government referral hospital, which admits up to 3000 children per month. A study published in 2013 reported mortality rates as high as 9%. This is the first known audit of pediatric death files conducted at this hospital. METHODS: A retrospective chart review on all pediatric deaths that occurred at Kamuzu Central Hospital (excluding deaths in the neonatal nursery) during a 13-month period was done using a standardized death audit form. A descriptive analysis was completed, including patient demographics, HIV and nutritional status, and cause of death. Modifiable factors were identified that may have contributed to mortality, including a lack of vital sign collection, poor documentation, and delays in the procurement or results of tests, studies, and specialist review. RESULTS: Seven hundred forty three total pediatric deaths were recorded and 700 deceased patient files were reviewed. The mortality rate by month ranged from a low of 2.2% to a high of 4.4%. Forty-four percent of deaths occurred within the first 24 h of admission, and 59% occurred within the first 48 h. The most common causes of death were malaria, malnutrition, HIV-related illnesses, and sepsis. CONCLUSIONS: The mortality rate for this pediatric referral center has dramatically decreased in the 6 years since the last published mortality data, but remains high. Areas identified for continued development include improved record keeping, improved patient assessment and monitoring, and more timely and reliable provision of testing and treatment. This study demonstrates that in low resource settings, where reliable record keeping is often difficult, death audits are useful tools to describe the sickest patient population and determine factors possibly contributing to mortality that may be amenable to quality improvement interventions. PMID- 29466968 TI - Palliative care specialists' perceptions concerning referral of haematology patients to their services: findings from a qualitative study. AB - BACKGROUND: Haematological malignancies (leukaemias, lymphomas and myeloma) are complex cancers that are relatively common, affect all ages and have divergent outcomes. Although the symptom burden of these diseases is comparable to other cancers, patients do not access specialist palliative care (SPC) services as often as those with other cancers. To determine the reasons for this, we asked SPC practitioners about their perspectives regarding the barriers and facilitators influencing haematology patient referrals. METHODS: We conducted a qualitative study, set within the United Kingdom's (UK's) Haematological Malignancy Research Network (HMRN: www.hmrn.org ), a population-based cohort in the North of England. In-depth, semi-structured interviews were conducted with 20 SPC doctors and nurses working in hospital, community and hospice settings between 2012 and 2014. Interviews were digitally audio-recorded, transcribed and analysed for thematic content using the 'Framework' method. RESULTS: Study participants identified a range of barriers and facilitators influencing the referral of patients with haematological malignancies to SPC services. Barriers included: the characteristics and pathways of haematological malignancies; the close patient/haematology team relationship; lack of role clarity; late end of life discussions and SPC referrals; policy issues; and organisational issues. The main facilitators identified were: establishment of inter-disciplinary working patterns (co-working) and enhanced understanding of roles; timely discussions with patients and early SPC referral; access to information platforms able to support information sharing; and use of indicators to 'flag' patients' needs for SPC. Collaboration between haematology and SPC was perceived as beneficial and desirable, and was said to be increasing over time. CONCLUSIONS: This is the first UK study to explore SPC practitioners' perceptions concerning haematology patient referrals. Numerous factors were found to influence the likelihood of referral, some of which related to the organisation and delivery of SPC services, so were amenable to change, and others relating to the complex and unique characteristics and pathways of haematological cancers. Further research is needed to assess the extent to which palliative care is provided by haematology doctors and nurses and other generalists and ways in which clinical uncertainty could be used as a trigger, rather than a barrier, to referral. PMID- 29466969 TI - Reliability and validity of measuring scale for postoperative complications in third molar surgery. AB - BACKGROUND: Third molar removal surgery is the most frequently performed surgery in the oral and maxillofacial field with a wide range of items in the quantification of postoperative complications. For their measure, in 2014 a previous scale design was presented. The aim of this study was to determine the reliability and validity of a scale designed to measure and quantify postoperative complications in third molar surgery (TMS). METHODS: A cross sectional study of a measurement model was designed. Sixty-two patients (mean age 20.5 +/- 6.6 years; 36 women) underwent TMS in three Chilean hospitals. In the postoperative check-up on the 7th day, a maxillofacial surgeon and a surgical resident performed independent postoperative assessments, applying the scale. A confirmatory factor analysis was conducted to obtain validity, internal consistency, interobserver reliability and a score to categorize the severity of complications using structural equation model analysis. RESULTS: Nine patients (14.5%) had complications. The scale was defined by two components: "Secondary complication" and "Infection" (Cronbach's alpha 0.71; Interobserver reliability 87.7%) and three categories of postoperative complication: "without or mild", "moderate" and "severe". CONCLUSION: This study presents a reliability and validity scale called "Surgical complication assessment scale in TMS". PMID- 29466970 TI - A novel combined systemic inflammation-based score can predict survival of intermediate-to-advanced hepatocellular carcinoma patients undergoing transarterial chemoembolization. AB - BACKGROUND: There is currently limited information regarding the prognostic ability of the dNLR-PNI (the combination of the derived neutrophil-to-lymphocyte ratio [dNLR] and prognostic nutritional index [PNI]) for hepatocellular carcinoma (HCC). This study aimed to assess the predictive ability of the dNLR-PNI in patients with intermediate-to-advanced HCC after transarterial chemoembolization (TACE). METHODS: A total of 761 HCC patients were enrolled in the study. The dNLR PNI was retrospectively calculated in these patients, as follows: patients with both an elevated dNLR and a decreased PNI, as determined using the cutoffs obtained from receiver operating characteristic curve analysis, were allocated a score of 2, while patients showing one or neither of these alterations were allocated a score of 1 or 0, respectively. RESULTS: During the follow-up period, 562 patients died. Multivariate analysis suggested that elevated total bilirubin, Barcelona Clinic Liver Cancer C stage, repeated TACE, and dNLR-PNI were independently associated with unsatisfactory overall survival. The median survival times of patients with a dNLR-PNI of 0, 1, and 2 were 31.0 (95% confidence interval [CI] 22.5-39.5), 16.0 (95% CI 12.2-19.7) and 6.0 (95% CI 4.8 7.2) months, respectively (P < 0.001). CONCLUSIONS: The dNLR-PNI can predict the survival outcomes of intermediate-to-advanced HCC patients undergoing TACE, and should be further evaluated as a prognostic marker for who are to undergo TACE treatment. PMID- 29466971 TI - Perioperative dynamics and significance of plasma-free amino acid profiles in colorectal cancer. AB - BACKGROUND: For early detection of cancer, we have previously developed the AminoIndex Cancer Screening (AICS) system, which quantifies 6 plasma-free amino acids (PFAAs) in blood samples. Herein, we examined the usefulness of the AICS in patients with colorectal cancer (CRC) by comparing the preoperative and postoperative PFAA profiles. METHODS: Our study cohort consisted of 62 patients who had undergone curative resection for CRC at our cancer center, with no recurrence at the time of the study. Blood samples were collected from fasted patients within 1 week before the resection and at 0.5-6.5 years post-resection. Following plasmapheresis, the PFAA levels were measured via liquid chromatography/mass spectrometry, and the AICS values were computed (the higher the value, the greater the probability of cancer). Risk was calculated from the AICS value and ranked as A, B, or C, with rank C representing the highest risk. All patients in our study were rank B + C. RESULTS: The postoperative AICS value was lower than the preoperative value in 57 of the 62 patients; the rank was also lower postoperatively (49 patients, p < 0.001). The decline in both was stage independent, even occurring in patients with right-sided tumors or poorly differentiated adenocarcinomas. For comparative purposes, the levels of 2 tumor markers (carbohydrate antigen 19-9 and carcinoembryonic antigen) were also examined; these were within the reference ranges in 70-80% of patients preoperatively and in 80-90% postoperatively. CONCLUSION: We suggest that tumor bearing conditions alter the PFAA profiles, which may be used to predict prognosis and monitor for recurrence in CRC patients after tumor resection. TRIAL REGISTRATION: This trial has been retrospectively registered at UMIN-CTR R000028005 , Oct 06, 2016. PMID- 29466972 TI - Is there a causal effect of parity on body composition: a birth cohort study. AB - BACKGROUND: Non-communicable diseases are the leading cause of death, worldwide. Obesity is one of the factors that is associated with the development of such diseases. The role of reproductive factors on women body composition has been evaluated, but the findings are controversial. This study was aimed at assessing the association of parity with body composition among women. METHODS: In 1982, the maternity hospital of Pelotas, a southern Brazilian city, were visited daily and all deliveries were identified. Those livebirths whose family lived in the urban area of the city have been prospectively followed (n = 5914). In 2012-13, we tried to follow the whole cohort, the subjects were interviewed and examined. We evaluated the association of parity with the following body composition variables: body mass index, waist circumference and fat mass %. Estimates were adjusted for family income, skin color, maternal schooling, occupational status, alcohol, smoking, physical activity, and consumption of processed and ultraprocessed foods. All these analyses were replicated among the cohort men as a comparison. We also assessed whether duration of breastfeeding moderated the association. RESULTS: In the 2012-13 visit, 3701 subjects were evaluated (mean age of 30.2 years). In the present analysis, we included 1620 women and 1653 men. 33% of women were nulliparous and 48% of men were without children. Even after controlling for confounding, parous women had a BMI 0.96 kg/m2 (95% CI: 0.30; 1.62) higher than nulliparous and for men the regression coefficient was 0.79 kg/m2 (95% CI: 0.29; 1.29). Waist circumference was also higher among parous women. Among men, the association was not linear and the regression coefficients were lower than that observed among women [3.41 cm (95% CI: -0.91; 7.73) among men and 4.83 cm (95% CI: 2.43; 7.24) among women with more than 3 children when compared with those without children], but this difference was not statistically significant (interaction p value = 0.58). Fat mass % was not associated with parity. Breastfeeding did not modify the association between parity and body composition. CONCLUSIONS: Parity was positively associated with body mass index and waist circumference among women. However, similar results among men suggest that there is no causal effect of parity.

AB - BACKGROUND: Aberrant crypt foci (ACF) are commonly considered the early pre cancerous lesions that can progress to colorectal cancer (CRC). The available literature data reveal that age, dietary factors and lifestyle can affect the development of several dozen percentages of malignant tumours, including CRC. In the present study, an attempt was made to assess the incidence and growth dynamics of ACF and to determine whether the type of diet affected the development and number of AFC. METHODS: Colonoscopy combined with rectal mucosa staining with 0.25% methylene blue was performed in 131 patients. On the day of examination, each patient completed a questionnaire regarding epidemiological data. According to their numbers, colorectal ACF were divided into three groups. The findings were analysed statistically. The Student's t test and the U test were applied in order to determine the significance of differences of means and frequency of events in both groups. Statistica 7.1 and Excel 2010 were used. RESULTS: The single ACF occur in the youngest individuals (ACF < 5). Since the age of 38 years, the number of ACF gradually increases to show a decreasing tendency since the age of 60 years. The number of 5 < ACF < 10 occurs slightly later, since the age of 50 years, and dynamically increases reaching the maximum at the age of 62 years, subsequently the increase is proportional. ACF > 10 occur at a more advanced age (55 years) and their number gradually increases with age. The maximum number is observed at the age of 77 years. In individuals not using high-fibre diets and with high intake of red meat, the probability of higher numbers of ACF increases. The probability of higher numbers of ACF (5 < ACF10) was observed in patients with colon diverticula. In patients with higher BMI, the number of ACF is higher. CONCLUSION: Age significantly affects the number of colorectal ACF. The types of foods consumed can considerably increase the risk of colorectal ACF, which is particularly visible in individuals who do not regularly use high-fibre diets, those obese and with colon diverticula. PMID- 29466974 TI - Temporary employment and tooth loss: a cross-sectional study from the J-SHINE study. AB - BACKGROUND: Temporary employment leads to psychological distress and higher mortality, but data on its associations with oral health is limited. We examined whether having the experience of temporary employment was associated with tooth loss among working adults in Japan. METHODS: We conducted a cross-sectional study from the 2010-2011 Japanese Study on Stratification, Health, Income, and Neighborhood study that analyzed 2652 participants aged 25-50 years (men = 1394; women = 1258). Independent variable was changes in employment status (continuous regular employment and the experience of temporary employment). Dependent variable was self-reported tooth loss (none, 1 tooth, 2 teeth, 3 teeth, 4 teeth, and more than 4 teeth). Covariates were sex, age, years of education, self-rated household economic status in early life at 5 years old, marital status, number of family members in the household, history of diabetes, and body mass index. We conducted a negative binomial regression analysis to estimate prevalence rate ratios (PRRs) and 95% confidence intervals (95%CIs) for tooth loss. We also confirmed the interaction term between changes in employment status and sex. RESULTS: The median age of the participants was 37 years. The percentages of men and women who experienced temporary employment were 14.5% and 61.3%, respectively. Compared with continuous regular employment, the experience of temporary employment was significantly associated with tooth loss in both sexes after adjusting for the covariates (men: PRR = 1.50 [95%CI = 1.13, 2.00]; women: PRR = 1.42 [95%CI = 1.14, 1.76]). The interaction term between employment status and sex was not significant (p = 0.71). CONCLUSIONS: Temporary employment is adversely associated with oral health. PMID- 29466975 TI - The impact of alcohol among injury patients in Moshi, Tanzania: a nested case crossover study. AB - BACKGROUND: Globally, alcohol is responsible for 3.3 million deaths annually and contributes to 5.9% of the overall global burden of disease. In Sub-Saharan Africa, alcohol is the leading avoidable risk factor accounting for a substantial portion of death and disability. This project aimed to determine the proportion of injuries related to alcohol and the increased risk of injury due to alcohol among injury patients seeking care at the emergency department (ED) of Kilimanjaro Christian Medical Centre (KCMC) in Moshi, Tanzania. METHODS: A representative cross-sectional sample of adult patients presenting to the KCMC ED with acute injury were enrolled in this study with a nested case-crossover design. Patient demographics, injury characteristics, and severity as well as alcohol use behaviors were collected. Alcohol breathalyzers were administered to the enrolled patients. Data on activities and alcohol use were collected for the time period 6 h prior to injury and two control periods: 24-30 h prior to injury and 1 week prior to injury. RESULTS: During 47 weeks of data collection, 24,070 patients were screened, of which 2164 suffered injuries, and 516 met the inclusion and exclusion criteria, consented to participate, and had complete data. Of the study participants, 76% were male, and 30% tested positive for alcohol on arrival to the ED. Alcohol use was associated with being male and being employed. Alcohol use was associated with an increased risk of injury (OR 5.71; 95% CI 3.84-8.50), and specifically road traffic injuries were associated with the highest odds of injury with alcohol use (OR 6.53, 95% CI 3.98-10.71). For all injuries and road traffic injuries specifically, we found an increase in the odds of injury with an incremental increase in the dose of alcohol. CONCLUSIONS: At KCMC in Moshi, Tanzania, 3 of 10 injury patients tested positive for alcohol on presentation for care. Similarly, alcohol use conveys an increased risk for injury in this setting. Evidence-based prevention strategies for alcohol related injuries need to be implemented to reduce alcohol misuse and alcohol related injuries.

AB - BACKGROUND: The ecosystems across Tibetan Plateau are changing rapidly under the influence of climate warming, which has caused substantial changes in spatial and temporal environmental patterns. Stipa purpurea, as a dominant herbsage resource in alpine steppe, has a great influence on animal husbandry in the Tibetan Plateau. Global warming has been forecasted to continue in the future (2050s, 2070s), questioning the future distribution of S. purpurea and its response to climate change. The maximum entropy (MaxEnt) modeling, due to its multiple advantages (e.g. uses presence-only data, performs well with incomplete data, and requires small sample sizes and gaps), has been used to understand species environment relationships and predict species distributions across locations that have not been sampled. RESULTS: Annual mean temperature, annual precipitation, temperature seasonality, altitude, and precipitation during the driest month, significantly affected the distribution of S. purpurea. Only 0.70% of the Tibetan Plateau area included a very highly suitable habitat (habitat suitability [HS] = 0.8-1.0). Highly suitable habitat (HS = 0.6-0.8), moderately suitable habitat (HS = 0.4-0.6), and unsuitable habitat (HS = 0.2-0.4) occupied 6.20, 14.30 and 22.40% of the Tibetan Plateau area, respectively, and the majority (56.40%) of the Tibetan Plateau area constituted a highly unsuitable habitat (HS = 0-0.2). In addition, the response curves of species ecological suitability simulated by generalized additive model nearly corresponded with the response curves generated by the MaxEnt model. CONCLUSIONS: At a temporal scale, the habitat suitability of S. purpurea tends to increase from the 1990s to 2050s, but decline from the 2050s to 2070s. At a spatial scale, the future distribution of S. purpurea will not exhibit sweeping changes and will remain in the central and southeastern regions of the Tibetan Plateau. These results benefit the local animal husbandry and provide evidence for establishing reasonable management practices. PMID- 29466977 TI - The Rotterdam Elderly Pain Observation Scale (REPOS) is reliable and valid for non-communicative end-of-life patients. AB - BACKGROUND: In palliative care, administration of opioids is often indispensable for pain treatment. Pain assessment may help recognize pain and guide treatment in non-communicative patients. In the Netherlands the Rotterdam Elderly Pain Observation Scale (REPOS) is recommended to this aim, but not yet validated. Therefore the objective of this study was to validate the REPOS in non communicative or unconscious end-of-life patients. METHODS: In this observational study, the primary researcher applied the REPOS, while both the researcher and a nurse applied the Numeric Rating Scale (NRS). If possible, the patient in question applied the NRS as well. The NRS scores were compared with the REPOS scores to determine concurrent validity. REPOS scores obtained before and after a pain-reducing intervention were analysed to establish the scale's sensitivity to change. RESULTS: A total of 183 REPOS observations in 100 patients were analysed. Almost 90% of patients had an advanced malignancy; observations were done a median of 3 days (IQR 1 to 13) before death. Internal consistency of the REPOS was 0.73. The Pearson product moment correlation coefficient ranged from 0.64 to 0.80 between REPOS and NRS scores. REPOS scores declined with median 2 points (IQR 1 to 4) after a pain-reducing intervention (p < 0.001). Optimal sensitivity (0.81) and specificity (0.62) were found at cut-off score 3. CONCLUSIONS: This study demonstrates that the REPOS has promising psychometric properties for pain assessment in non-communicative end-of-life patients. Its application may be of additional value to relieve suffering, including pain, in palliative care. PMID- 29466978 TI - Repeated electroacupuncture treatment attenuated hyperalgesia through suppression of spinal glial activation in chronic neuropathic pain rats. AB - BACKGROUND: Cumulated evidence reveals that glial cells in the spinal cord play an important role in the development of chronic neuropathic pain and are also complicated in the analgesic effect of EA intervention. But the roles of microgliacytes and astrocytes of spinal cord in the process of EA analgesia remain unknown. METHODS: A total of 120 male Wistar rats were used in the present study. The neuropathic pain model was established by chronic constrictive injury (CCI) of the sciatic nerve. The rats were randomly divided into sham group, CCI group, and sham CCI + EA group, and CCI + EA group. EA was applied to bilateral Zusanli (ST36)-Yanlingquan (GB34). The mechanical (both time and force responses) and thermal pain thresholds (PTs) of the bilateral hind-paws were measured. The number of microgliacytes and activity of astrocytes in the dorsal horns (DHs) of lumbar spinal cord (L4-5) were examined by immunofluorescence staining, and the expression of glial fibrillary acidic protein (GFAP) protein was detected by western blot. RESULTS: Following CCI, both mechanical and thermal PTs of the ipsilateral hind-paw were significantly decreased beginning from the 3rd day after surgery (P < 0.05), and the mechanical PT of the contralateral hind-paw was considerably decreased from the 6th day on after surgery (P < 0.05). CCI also significantly upregulated the number of Iba-1 labeled microgliacytes and the fluorescence intensity of glial fibrillary acidic protein (GFAP) -labeled astrocyte in the superficial laminae of DHs on bilateral sides (P < 0.05). After repeated EA, the mechanical and thermal PTs at bilateral hind-paws were significantly relieved (P < 0.05). The increased of number of microgliacytes was markedly suppressed by 2 days' EA intervention, and the average fluorescence intensity was suppressed by 2 weeks' EA. The expression of GFAP protein were down regulated by 1 and 2 weeks' EA treatment, respectively (P < 0.05). CONCLUSIONS: Repeated EA can relieve neuropathic pain and mirror-image pain in chronic neuropathic pain rats, which is probably associated with its effect in downregulating glial cell activation of the lumbar spinal cord, the microgliacyte first and astrocyte later. PMID- 29466979 TI - The high need for trials assessing functional outcome after stroke rather than stroke prevention with GLP-1 agonists and DPP-4 inhibitors. PMID- 29466980 TI - The benefits of co-location in primary care practices: the perspectives of general practitioners and patients in 34 countries. AB - BACKGROUND: There is no clear evidence as to whether the co-location of primary care professionals in the same facility positively influences their way of working and the quality of healthcare as perceived by patients. The aim of this study was to identify the relationships between general practitioner (GP) co location with other GPs and/or other professionals and the GP outcomes and patients' experiences. METHODS: We wanted to test whether GP co-location is related to a broader range of services provided, the use of clinical governance tools and inter-professional collaboration, and whether the patients of co located GPs perceive a better quality of care in terms of accessibility, comprehensiveness and continuity of care with their GPs. The source of data was the QUALICOPC study (Quality and Costs of Primary Care in Europe), which involved surveys of GPs and their patients in 34 countries, mostly in Europe. In order to study the relationships between GP co-location and both GPs' outcomes and patients' experience, multilevel linear regression analysis was carried out. RESULTS: The GP questionnaire was filled in by 7183 GPs and the patient experience questionnaire by 61,931 patients. Being co-located with at least one other professional is the most common situation of the GPs involved in the study. Compared with single-handed GP practices, GP co-location are positively associated with the GP outcomes. Considering the patients' perspective, comprehensiveness of care has the strongest negative relationship of GP co location of all the dimensions of patient experiences analysed. CONCLUSIONS: The paper highlights that GP mono- and multi-disciplinary co-location is related to positive outcomes at a GP level, such as a broader provision of technical procedures, increased collaboration among different providers and wider coordination with secondary care. However, GP co-location, particularly in a multidisciplinary setting, is related to less positive patient experiences, especially in countries with health systems characterised by a weak primary care structure. PMID- 29466981 TI - A novel purified Lactobacillus acidophilus 20079 exopolysaccharide, LA-EPS-20079, molecularly regulates both apoptotic and NF-kappaB inflammatory pathways in human colon cancer. AB - BACKGROUND: The direct link between inflammatory bowel diseases and colorectal cancer is well documented. Previous studies have reported that some lactic acid bacterial strains could inhibit colon cancer progression however; the exact molecules involved have not yet been identified. So, in the current study, we illustrated the tumor suppressive effects of the newly identified Lactobacillus acidophilus DSMZ 20079 cell-free pentasaccharide against colon cancer cells. The chemical structure of the purified pentasaccharide was investigated by MALDI-TOF mass spectrum, 1D and 2D Nuclear Magnetic Resonance (NMR). The anticancer potentiality of the purified pentasaccharide against both Human colon cancer (CaCo-2) and Human breast cancer (MCF7) cell lines with its safety usage pattern were evaluated using cytotoxicity, annexin V quantification and BrdU incorporation assays. Also, the immunomodulatory effects of the identified compound were quantified on both LPS-induced PBMC cell model and cancer cells with monitoring the immunophenotyping of T and dendritic cell surface marker. At molecular level, the alteration in gene expression of both inflammatory and apoptotic pathways were quantified upon pentasaccharide-cellular treatment by RTqPCR. RESULTS: The obtained data of the spectroscopic analysis, confirmed the structure of the newly extracted pentasaccharide; (LA-EPS-20079) to be: alpha-D Glc (1->2)][alpha-L-Fuc(1->4)] alpha-D-GlcA(1->2) alpha-D-GlcA(1->2) alpha-D GlcA. This pentasaccharide, recorded safe dose on normal mammalian cells ranged from 2 to 5 mg/ml with cancer cells selectivity index, ranged of 1.96-51.3. Upon CaCo-2 cell treatment with the non-toxic dose of LA-EPS-20079, the inhibition percentage in CaCo-2 cellular viability, reached 80.65 with an increase in the ratio of the apoptotic cells in sub-G0/G1 cell cycle phase. Also, this pentasaccharide showed potentialities to up-regulate the expression of IKbalpha, P53 and TGF genes. CONCLUSION: The anticancer potentialities of LA-EPS-20079 oligosaccharides against human colon cancer represented through its regulatory effects on both apoptotic and NF-kappaB inflammatory pathways. PMID- 29466982 TI - Early-life exposure to PM2.5 and risk of acute asthma clinical encounters among children in Massachusetts: a case-crossover analysis. AB - BACKGROUND: Associations between ambient particulate matter < 2.5 MUm (PM2.5) and asthma morbidity have been suggested in previous epidemiologic studies but results are inconsistent for areas with lower PM2.5 levels. We estimated the associations between early-life short-term PM2.5 exposure and the risk of asthma or wheeze clinical encounters among Massachusetts children in the innovative Pregnancy to Early Life Longitudinal (PELL) cohort data linkage system. METHODS: We used a semi-bidirectional case-crossover study design with short-term exposure lags for asthma exacerbation using data from the PELL system. Cases included children up to 9 years of age who had a hospitalization, observational stay, or emergency department visit for asthma or wheeze between January 2001 and September 2009 (n = 33,387). Daily PM2.5 concentrations were estimated at a 4-km resolution using satellite remote sensing, land use, and meteorological data. We applied conditional logistic regression models to estimate adjusted odds ratios (ORs) and 95% confidence intervals (CI). We also stratified by potential effect modifiers. RESULTS: The median PM2.5 concentration among participants was 7.8 MUg/m3 with an interquartile range of 5.9 MUg/m3. Overall, associations between PM2.5 exposure and asthma clinical encounters among children at lags 0, 1 and 2 were close to the null value of OR = 1.0. Evidence of effect modification was observed by birthweight for lags 0, 1 and 2 (p < 0.05), and season of clinical encounter for lags 0 and 1 (p < 0.05). Children with low birthweight (LBW) (< 2500 g) had increased odds of having an asthma clinical encounter due to higher PM2.5 exposure for lag 1 (OR: 1.08 per interquartile range (IQR) increase in PM2.5; 95% CI: 1.01, 1.15). CONCLUSION: Asthma or wheeze exacerbations among LBW children were associated with short-term increases in PM2.5 concentrations at low levels in Massachusetts.

PMID- 29466983 TI - Multidrug-resistant tuberculosis treatment adherence in migrants: a systematic review and meta-analysis. AB - BACKGROUND: Multidrug-resistant tuberculosis (MDR-TB) is a growing concern in meeting global targets for TB control. In high-income low-TB-incidence countries, a disproportionate number of MDR-TB cases occur in migrant (foreign-born) populations, with concerns about low adherence rates in these patients compared to the host non-migrant population. Tackling MDR-TB in this context may, therefore, require unique approaches. We conducted a systematic review and meta analysis to identify and synthesise data on MDR-TB treatment adherence in migrant patients to inform evidence-based strategies to improve care pathways and health outcomes in this group. METHODS: This systematic review and meta-analysis was conducted in line with PRISMA guidelines (PROSPERO 42017070756). The databases Embase, MEDLINE, Global Health and PubMed were searched to 24 May 2017 for primary research reporting MDR-TB treatment adherence and outcomes in migrant populations, with no restrictions on dates or language. A meta-analysis was conducted using random-effects models. RESULTS: From 413 papers identified in the database search, 15 studies reporting on MDR-TB treatment outcomes for 258 migrants and 174 non-migrants were included in the systematic review and meta analysis. The estimated rate of adherence to MDR-TB treatment across migrant patients was 71% [95% confidence interval (CI) = 58-84%], with non-adherence reported among 20% (95% CI = 4-37%) of migrant patients. A key finding was that there were no differences in estimated rates of adherence [risk ratio (RR) = 1.05; 95% CI = 0.82-1.34] or non-adherence (RR = 0.97; 95% CI = 0.79-1.36) between migrants and non-migrants. CONCLUSIONS: MDR-TB treatment adherence rates among migrants in high-income low-TB-incidence countries are approaching global targets for treatment success (75%), and are comparable to rates in non-migrants. The findings highlight that only just over 70% of migrant and non-migrant patients adhere to MDR-TB treatment. The results point to the importance of increasing adherence in all patient groups, including migrants, with an emphasis on tailoring care based on social risk factors for poor adherence. We believe that MDR-TB treatment targets are not ambitious enough. PMID- 29466985 TI - Association between plasma fatty acids and inflammatory markers in patients with and without insulin resistance and in secondary prevention of cardiovascular disease, a cross-sectional study. AB - BACKGROUND: Proinflammatory biomarkers levels are increased among patients with cardiovascular disease, and it is known that both the presence of insulin resistance and diet may influence those levels. However, these associations are not well studied among patients with established cardiovascular disease. Our objective is to compare inflammatory biomarker levels among cardiovascular disease secondary prevention patients with and without insulin resistance, and to evaluate if there is any association between plasma fatty acid levels and inflammatory biomarker levels among them. METHODS: In this cross-sectional sub study from the BALANCE Program Trial, we collected data from 359 patients with established cardiovascular disease. Plasma fatty acids and inflammatory biomarkers (interleukin (IL)-1beta, IL-6, IL-8, IL-10, IL-12, high sensitive C reactive protein (hs-CRP), adiponectin, and tumor necrosis factor (TNF)-alpha) were measured. Biomarkers and plasma fatty acid levels of subjects across insulin resistant and not insulin resistant groups were compared, and general linear models were used to examine the association between plasma fatty acids and inflammatory biomarkers. RESULTS: Subjects with insulin resistance had a higher concentration of hs-CRP (p = 0.002) and IL-6 (p = 0.002) than subjects without insulin resistance. Among subjects without insulin resistance there was a positive association between stearic fatty acid and IL-6 (p = 0.032), and a negative association between alpha-linolenic fatty acid and pro-inflammatory biomarkers (p < 0.05). Among those with insulin resistance there was a positive association between monounsaturated fatty acids and arachidonic fatty acid and adiponectin (p < 0.05), and a negative association between monounsaturated and polyunsaturated fatty acids and pro-inflammatory biomarkers (p < 0.05), as well as a negative association between polyunsaturated fatty acids and adiponectin (p < 0.05). Our study has not found any association between hs-CRP and plasma fatty acids. CONCLUSIONS: Subjects in secondary prevention for cardiovascular disease with insulin resistance have a higher concentration of hs-CRP and IL-6 than individuals without insulin resistance, and these inflammatory biomarkers are positively associated with saturated fatty acids and negatively associated with unsaturated fatty acids. PMID- 29466986 TI - The role of kinesin KIF18A in the invasion and metastasis of hepatocellular carcinoma. AB - BACKGROUND: KIF18A is associated with a variety of tumours; however, the specific mechanism of action of KIF18A in hepatocellular carcinoma (HCC) remains unclear. In this study, in vitro and in vivo experiments were performed with the aim of exploring the potential function and molecular mechanism of kinesin KIF18A in the occurrence and development of HCC. METHODS: We detected the expression of KIF18A in tumour and adjacent tissues as well as cell proliferation, cell invasion and migration in hepatoma cells after silencing KIF18A. KIF18A-silenced hepatoma cells were subcutaneously injected into nude mice to verify the tumorigenicity of KIF18A. We also detected the expression of signal pathway-related proteins in hepatoma cells after KIF18A knockdown with the aim of exploring the association between KIF18A and related signalling pathways. RESULTS: The level of KIF18A protein was higher in liver cancer tissues than adjacent tissues. After silencing KIF18A in SMMC-7721 and HepG2 cells, cell growth was obviously inhibited; the migration and invasion abilities were significantly decreased and the in vivo tumour weight was decreased compared to the control group (0.201 +/- 0.088 g vs 0.476 +/- 0.126 g, p = 0.009). The expression of cell cycle-related protein (cyclin B1), invasion and metastasis-related proteins (MMP-7 and MMP-9) and Akt related proteins in hepatoma cells was also decreased after knocking down KIF18A. CONCLUSIONS: KIF18A may promote proliferation, invasion and metastasis of HCC cells by promoting the cell cycle signalling pathway as well as the Akt and MMP 7/MMP-9-related signalling pathways and may serve as a new target for the diagnosis and treatment of HCC. PMID- 29466987 TI - Antioxidant capacities and total phenolic contents of 20 polyherbal remedies used as tonics by folk healers in Phatthalung and Songkhla provinces, Thailand. AB - BACKGROUND: Uses of polyherbal formulations have played a major role in traditional medicine. The present study is focused on the formulations used in traditional Thai folkloric medicine as tonics or bracers. Twenty documented polyherbal mixtures, used as nourishing tonics by the folk healers in Phatthalung and Songkhla provinces in southern Thailand, are targeted. Despite traditional health claims, there is no scientific evidence to support the utilization of polyherbal formulations. METHODS: The phenolic and flavonoid contents of the polyherbal formulations and a series of antioxidant tests were applied to measure their capability as preventive or chain-breaking antioxidants. In addition, the cytotoxic activity of effective formulations was assayed in Vero cells. RESULTS: Ninety-eight plant species belonging to 45 families were used to prepare the tested formulation. The preliminary results revealed that water extracts of THP R016 and THP-R019 contain a high level of total phenolic and flavonoid contents and exhibit remarkable antioxidant activities, as tested by DPPH, ABTS, and FRAP assays. The extract of THP-R019 also showed the strongest metal chelating activities, whereas THP-R016 extract possessed notable superoxide anion and peroxyl radical scavenging abilities. CONCLUSIONS: The data provide evidence that the water extracts of folkloric polyherbal formulations, particularly THP-R016, are a potential source of natural antioxidants, which will be valuable in the pharmaceutical and nutraceutical industries. The free radical scavenging of THP R016 may be due to the contribution of phenolic and flavonoid contents. Useful characteristics for the consumer, such as the phytochemical profiles of active ingredients, cellular based antioxidant properties and beneficial effects in vivo, are under further investigation. PMID- 29466988 TI - Blood flow characteristics of diabetic patients with complications detected by optical measurement. AB - BACKGROUND: Diabetes mellitus (DM) is one of the most common diseases worldwide. Uncontrolled and prolonged hyperglycemia can cause diabetic complications, which reduce the quality of life of patients. Diabetic complications are common in DM patients. Because it is impossible to completely recover from diabetic complications, it is important for early detection. In this study, we suggest a novel method of determining blood flow characteristics based on fluorescence image analysis with indocyanine green and report that diabetic complications have unique blood flow characteristics. METHODS: We analyzed time-series fluorescence images obtained from controls, DM patients, and DM patients with complications. The images were segmented into the digits and the dorsum of the feet and hands, and each part has been considered as arterial and capillary flow. We compared the blood flow parameters in each region among the three groups. RESULTS: The DM patients with complications showed similar blood flow parameters to the controls, except the area under the curve and the maximum intensity, which indicate the blood flow volume. These parameters were significantly decreased in DM patients with complications. Although some blood flow parameters in the feet of DM patients with complications were close to normal blood flow, the vascular response of the macrovessels and microvessels to stimulation of the hands was significantly reduced, which indicates less reactivity in DM patients with complications. CONCLUSIONS: Our results suggest that DM patients, and DM patients with complications, have unique peripheral blood flow characteristics. PMID- 29466989 TI - Sweet attraction: sugarcane pollen-associated volatiles attract gravid Anopheles arabiensis. AB - BACKGROUND: Anopheles arabiensis is a key vector for the transmission of human malaria in sub-Saharan Africa. Over the past 10,000 years, humans have successfully cultivated grasses and altered the landscape, creating An. arabiensis favourable environments that contain excellent habitats for both larvae and adults. Sugarcane is the most expanding agricultural system in sub Saharan Africa, and is linked to the increased threat of malaria in rural communities. The prolific production and wind dispersal of sugarcane pollen, together with standing pools of water, often provide, as a result of irrigation, a nutrient-rich environment for the offspring of gravid malaria mosquitoes. RESULTS: In the present study, sugarcane pollen-associated volatiles from two cultivars are shown to attract gravid An. arabiensis in a still air two-port olfactometer and stimulate egg laying in an oviposition bioassay. Through combined gas chromatography and electroantennographic detection, as well as combined gas chromatography and mass spectrometric analyses, we identified the bioactive volatiles and generated a synthetic blend that reproduced the full behavioural repertoire of gravid mosquitoes in the Y-tube assay. Two subtractive odour blends, when compared with the full blend, were significantly more attractive. These three and four-component subtractive blends share the compounds (1R)-(+)-alpha-pinene, nonanal and benzaldehyde, of which, (1R)-(+)-alpha-pinene and nonanal are found in the attractive odour blends from rice plants and maize pollen. In pairwise comparisons, the rice synthetic odour blend was more attractive to gravid mosquitoes than either of the pollen blends, whereas the pollen blends did not differ in attraction. CONCLUSIONS: The attraction of gravid females to sugarcane pollen volatiles demonstrated in this study, together with the previously found grass-associated volatiles, raise the potential of developing a bioactive chimeric blend to attract gravid malaria mosquitoes. This is discussed in relation to the development of novel and cost-effective vector control measures. PMID- 29466990 TI - Targeting HER2-breast tumors with scFv-decorated bimodal nanoprobes. AB - BACKGROUND: Recent advances in nanomedicine have shown the great interest of active targeting associated to nanoparticles. Single chain variable fragments (scFv) of disease-specific antibodies are very promising targeting entities because they are small, not immunogenic and able to bind their specific antigens. The present paper is devoted to biological properties in vitro and in vivo of fluorescent and pegylated iron oxide nanoparticles (SPIONs-Cy-PEG-scFv) functionalized with scFv targeting Human Epithelial growth Receptor 2 (HER2). RESULTS: Thanks to a site-selective scFv conjugation, the resultant nanoprobes demonstrated high affinity and specific binding to HER2 breast cancer cells. The cellular uptake of SPIONs-Cy-PEG-scFv was threefold higher than that for untargeted PEGylated iron oxide nanoparticles (SPIONs-Cy-PEG) and is correlated to the expression of HER2 on cells. In vivo, the decrease of MR signals in HER2+ xenograft tumor is about 30% at 24 h after the injection. CONCLUSIONS: These results all indicate that SPIONs-Cy-PEG-scFv are relevant tumor-targeting magnetic resonance imaging agents, suitable for diagnosis of HER2 overexpressing breast tumor. PMID- 29466991 TI - Asymptomatic Plasmodium vivax parasitaemia in the low-transmission setting: the role for a population-based transmission-blocking vaccine for malaria elimination. AB - Plasmodium vivax remains an important cause of morbidity and mortality across the Americas, Horn of Africa, East and South East Asia. Control of transmission has been hampered by emergence of chloroquine resistance and several intrinsic characteristics of infection including asymptomatic carriage, challenges with diagnosis, difficulty eradicating the carrier state and early gametocyte appearance. Complex human-parasite-vector immunological interactions may facilitate onward infection of mosquitoes. Given these challenges, new therapies are being explored including the development of transmission to mosquito blocking vaccines. Herein, the case supporting the need for transmission-blocking vaccines to augment control of P. vivax parasite transmission and explore factors that are limiting eradication efforts is discussed. PMID- 29466992 TI - The HNF1alpha-regulated lncRNA HNF1A-AS1 reverses the malignancy of hepatocellular carcinoma by enhancing the phosphatase activity of SHP-1. AB - BACKGROUND: Our previous study has demonstrated that hepatocyte nuclear factor 1alpha (HNF1alpha) exerts potent therapeutic effects on hepatocellular carcinoma (HCC). However, the molecular mechanisms by which HNF1alpha reverses HCC malignancy need to be further elucidated. METHODS: lncRNA microarray was performed to identify the long noncoding RNAs (lncRNAs) regulated by HNF1alpha. Chromatin immunoprecipitation and luciferase reporter assays were applied to clarify the mechanism of the transcriptional regulation of HNF1alpha to HNF1A antisense RNA 1 (HNF1A-AS1). The effect of HNF1A-AS1 on HCC malignancy was evaluated in vitro and in vivo. RNA pulldown, RNA-binding protein immunoprecipitation and the Bio-Layer Interferometry assay were used to validate the interaction of HNF1A-AS1 and Src homology region 2 domain-containing phosphatase 1 (SHP-1). RESULTS: HNF1alpha regulated the expression of a subset of lncRNAs in HCC cells. Among these lncRNAs, the expression levels of HNF1A-AS1 were notably correlated with HNF1alpha levels in HCC cells and human HCC tissues. HNF1alpha activated the transcription of HNF1A-AS1 by directly binding to its promoter region. HNF1A-AS1 inhibited the growth and the metastasis of HCC cells in vitro and in vivo. Moreover, knockdown of HNF1A-AS1 reversed the suppressive effects of HNF1alpha on the migration and invasion of HCC cells. Importantly, HNF1A-AS1 directly bound to the C-terminal of SHP-1 with a high binding affinity (KD = 59.57 +/- 14.29 nM) and increased the phosphatase activity of SHP-1. Inhibition of SHP-1 enzymatic activity substantially reversed the HNF1alpha- or HNF1A-AS1-induced reduction on the metastatic property of HCC cells. CONCLUSIONS: Our data revealed that HNF1A-AS1 is a direct transactivation target of HNF1alpha in HCC cells and involved in the anti-HCC effect of HNF1alpha. HNF1A-AS1 functions as phosphatase activator through the direct interaction with SHP-1. These findings suggest that regulation of the HNF1alpha/HNF1A-AS1/SHP-1 axis may have beneficial effects in the treatment of HCC.

AB - BACKGROUND: While the admittedly limited number of epidemiological findings on the association between diet-related greenhouse gas emissions (GHGE) and diet quality are not always consistent, potential influence of bias in the estimation of diet-related GHGE caused by misreporting of energy intake (EI) has not been investigated. This cross-sectional study evaluated diet-related GHGE in the UK and their association with diet quality, taking account of EI under-reporting. METHODS: Dietary data used were from the National Diet and Nutrition Survey rolling programme 2008/2009-2013/2014, in which 4-day food diaries were collected from 3502 adults aged >=19 years. Diet-related GHGE were estimated based on 133 food groups, using GHGE values from various secondary sources. Diet quality was assessed by the healthy diet indicator (HDI), Mediterranean diet score (MDS) and Dietary Approaches to Stop Hypertension (DASH) score. EI misreporting was assessed as reported EI divided by estimated energy requirement (EI:EER). RESULTS: Mean value of daily GHGE was 5.7 kg carbon dioxide equivalents (CO2eq), which is consistent with those reported from a number of national representative samples in other European countries. Mean EI:EER was 0.74. Assuming that all the dietary variables were misreported in proportion to the misreporting of EI, the mean value of the misreporting-adjusted diet-related GHGE was 8.2 kg CO2eq/d. In the entire population, after adjustment for potential confounders (i.e., age, sex, ethnicity, socioeconomic classification, smoking status and physical activity), diet-related GHGE were inversely associated with HDI and DASH score but not with MDS. However, with further adjustment for EI:EER, diet-related GHGE showed inverse associations with all three measures of diet quality. Similar associations were observed when only under-reporters (EI:EER < 0.70; n = 1578) were analysed. Conversely, in the analysis including only plausible reporters (EI:EER 0.70-1.43; n = 1895), diet-related GHGE showed inverse associations with all diet quality measures irrespective of adjustment. CONCLUSIONS: With taking account of EI under-reporting, this study showed inverse associations between diet-related GHGE and diet quality not only in the entire sample but also in the separate analyses of plausible reporters and under-reporters, as well as potential underreporting of diet-related GHGE. PMID- 29466994 TI - Developing a framework to evaluate knowledge into action interventions. AB - BACKGROUND: There are many challenges in delivering and evaluating knowledge for healthcare, but the lack of clear routes from knowledge to practice is a root cause of failures in safety within healthcare. Various types and sources of knowledge are relevant at different levels within the healthcare system. These need to be delivered in a timely way that is useful and actionable for those providing services or developing policies. How knowledge is taken up and used through networks and relationships, and the difficulties in attributing change to knowledge-based interventions, present challenges to understanding how knowledge into action (K2A) work influences healthcare outcomes. This makes it difficult to demonstrate the importance of K2A work, and harness support for its development and resourcing. This paper presents the results from a project commissioned by NHS Education for Scotland (NES) and Healthcare Improvement Scotland (HIS) to create an evaluation framework to help understand the NHS Scotland Knowledge into Action model. METHODS: The team took a developmental approach to creating an evaluation framework that would be useful and practical. This included a literature review to ensure the evaluation was evidence-based; adaptation of contribution analysis for K2A project; action research with K2A project leads to refine the work and develop suitable measures. RESULTS: Principles for evaluation and an evaluation framework based on contribution analysis were developed and implemented on a trial project. An outcomes chain was developed for the K2A programme and specific projects. This was used to design, collect and collate evidence of the K2A intervention. Data collected routinely by the intervention was supplemented with specific feedback measures from K2A project users. CONCLUSIONS: The evaluation approach allowed for scrutiny of both processes and outcomes and was adaptable to projects on different scales. This framework has proved useful as a planning, reflecting and evaluation tool for K2A, and could be more widely used to evidence the ways in which knowledge to action work helps improve healthcare outcomes.

The emerging picture of cancer captures its extensive diversity and therapeutic resilience, highlighting the need for more innovative approaches to control. PMID- 29466996 TI - 'Just because she's young, it doesn't mean she has to die': exploring the contributing factors to high maternal mortality in adolescents in Eastern Freetown; a qualitative study. AB - BACKGROUND: In Sierra Leone, 34% of pregnancies and 40% of maternal deaths are in the adolescent population. Risks are known to be higher for younger adolescents, this being borne out by a household survey in Eastern Freetown in 2015. This current qualitative study, funded by Wellbeing of Women's international midwifery fellowship, was conducted to explore the causes of this high incidence of maternal death for younger teenagers, and to identify possible interventions to improve outcomes. METHODS: This qualitative study used semi-structured interviews (n = 19) and focus groups (n = 6), with a wide range of professional and lay participants, recorded with consent. Recordings were transcribed by the first author and a Krio-speaking colleague where necessary, and Nvivo software was used to assist with theming of the data around the three main research questions. RESULTS: Themes from discussions on vulnerability to teenage pregnancy focused on transactional sex, especially for girls living outside of their birth family. They included sex for school fees, sex with teachers for grades, sex for food and clothes, and sex to lessen the impact of the time-consuming duties of water collection and petty trading. In addition, the criminal justice system and the availability and accessibility of contraception and abortion were included within this major theme. Within the major theme of vulnerability to death once pregnant, abandonment, delayed care seeking, and being cared for by a non-parental adult were identified. Several obstetric risks were discussed by midwives, but were explicitly related to the socio-economic factors already mentioned. A cross cutting theme throughout the data was of gendered social norms for sexual behaviour, for both boys and girls, being reinforced by significant adults such as parents and teachers. CONCLUSION: Findings challenge the notion that adolescent girls have the necessary agency to make straightforward choices about their sexual behaviour and contraceptive use. For girls who do become pregnant, risks are believed to be related more to stigma and abandonment than to physical maturity, leading to lack of family-based support and delayed care-seeking for antenatal and delivery care. Two potential interventions identified within the research are a mentoring scheme for the most vulnerable pregnant girls and a locally managed blood donation register. A feasibility study of a pilot mentoring scheme is currently underway, run by the first author and a local partner. PMID- 29466997 TI - Hearing impairment in MELAS: new prospective in clinical use of microRNA, a systematic review. AB - AIM: To evaluate the feasibility of microRNAs (miR) in clinical use to fill in the gap of current methodology commonly used to test hearing impairment in MELAS patients. MATERIAL AND METHOD: A literature review was performed using the following keywords, i.e., MELAS, Hearing Loss, Hearing Impairment, Temporal Bone, Otoacustic Emission (OTOAE), Auditory Brain Response (ABR), and microRNA. We reviewed the literature and focused on the aspect of the temporal bone, the results of electrophysiological tests in human clinical studies, and the use of miR for detecting lesions in the cochlea in patients with MELAS. RESULTS: In patients with MELAS, Spiral Ganglions (SG), stria vascularis (SV), and hair cells are damaged, and these damages affect in different ways various structures of the temporal bone. The function of these cells is typically investigated using OTOAE and ABR, but in patients with MELAS these tests provide inconsistent results, since OTOAE response is absent and ABR is normal. The normal ABR responses are unexpected given the SG loss in the temporal bone. Recent studies in humans and animals have shown that miRs, and in particular miRs 34a, 29b, 76, 96, and 431, can detect damage in the cells of the cochlea with high sensitivity. Studies that focus on the temporal bone aspects have reported that miRs increase is correlated with the death of specific cells of the inner ear. MiR - 9/9* was identified as a biomarker of human brain damage, miRs levels increase might be related to damage in the central auditory pathways and these increased levels could identify the damage with higher sensitivity and several months before than electrophysiological testing. CONCLUSION: We suggest that due to their accuracy and sensitivity, miRs might help monitor the progression of SNHL in patients with MELAS. PMID- 29466998 TI - Contextually tailored interventions can increase evidence-informed policy-making on health-enhancing physical activity: the experiences of two Danish municipalities. AB - BACKGROUND: The present study aims to test out contextually tailored interventions to increase evidence-informed health-enhancing physical activity policy-making in two Danish municipalities. METHODS: The study was performed as experiments in natural settings. Based on results from a pre-intervention study defining the needs and contexts of the two settings, the interventions were developed based on logical models. The interventions aimed at increasing the use of knowledge in policy-making, primarily via strengthening intersectoral collaboration. The interventions were evaluated via pre-, post- and 12-month follow-up questionnaires and qualitative interviews were carried out prior to the intervention start. RESULTS: The use of knowledge changed in several ways. In one municipality, the use of stakeholder and target group knowledge increased whereas, in the other municipality, the use of research knowledge increased. In both municipalities, the ability to translate knowledge to local context, the political request and the organisational procedures for use of knowledge increased during the interventions. There was some variation between the two settings, which shows the importance of tailoring to context. Most of the changes were diminished at the 12-month follow-up. CONCLUSION: Contextually tailored interventions have the potential to increase evidence-informed policy-making on health-enhancing physical activity. However, this finding needs to be tested in larger samples and its sustainability must be strengthened. PMID- 29466999 TI - A probiotic complex, rosavin, zinc, and prebiotics ameliorate intestinal inflammation in an acute colitis mouse model. AB - BACKGROUND: An altered gut microbiota balance is involved in the pathogenesis of inflammatory bowel disease (IBD), and several probiotic strains are used as dietary supplements to improve intestinal health. We evaluated the therapeutic effect of 12 probiotics in combination with prebiotics, rosavin, and zinc in the dextran sodium sulfate (DSS)-induced colitis mouse model. METHODS: The probiotic complex or the combination drug was administered orally to mice with DSS-induced colitis, and the body weight, disease activity index, colon length, and histopathological parameters were evaluated. Also, the combination drug was applied to HT-29 epithelial cells, and the expression of monocyte chemoattractant protein 1 (MCP-1) was evaluated by real-time polymerase chain reaction. RESULTS: Administration of the combination drug attenuated the severity of DSS-induced colitis. Moreover, the combination drug significantly reduced the levels of the proinflammatory cytokines tumor necrosis factor-alpha, interleukin (IL)-6, IL 1beta, and IL-17, and significantly increased the levels of Foxp3 and IL-10 in colon sections. Additionally, treatment with the combination drug reduced MCP-1 expression in HT-29 cells. Treatment with the combination drug decreased the levels of alpha-smooth muscle actin and type I collagen compared with vehicle treatment in mice with DSS-induced colitis. CONCLUSION: These results suggest that the combination of a probiotic complex with rosavin, zinc, and prebiotics exerts a therapeutic effect on IBD by modulating production of pro- and anti inflammatory cytokines and the development of fibrosis. PMID- 29467000 TI - Ginsenoside Re protects methamphetamine-induced dopaminergic neurotoxicity in mice via upregulation of dynorphin-mediated kappa-opioid receptor and downregulation of substance P-mediated neurokinin 1 receptor. AB - BACKGROUND: We previously reported that ginsenoside Re (GRe) attenuated against methamphetamine (MA)-induced neurotoxicity via anti-inflammatory and antioxidant potentials. We also demonstrated that dynorphin possesses anti-inflammatory and antioxidant potentials against dopaminergic loss, and that balance between dynorphin and substance P is important for dopaminergic neuroprotection. Thus, we examined whether GRe positively affects interactive modulation between dynorphin and substance P against MA neurotoxicity in mice. METHODS: We examined changes in dynorphin peptide level, prodynorphin mRNA, and substance P mRNA, substance P immunoreactivity, homeostasis in enzymatic antioxidant system, oxidative parameter, microglial activation, and pro-apoptotic parameter after a neurotoxic dose of MA to clarify the effects of GRe, prodynorphin knockout, pharmacological inhibition of kappa-opioid receptor (i.e., nor-binaltorphimine), or neurokinin 1 (NK1) receptor (i.e., L-733,060) against MA insult in mice. RESULTS: GRe attenuated MA-induced decreases in dynorphin level, prodynorphin mRNA expression in the striatum of wild-type (WT) mice. Prodynorphin knockout potentiated MA induced dopaminergic toxicity in mice. The imbalance of enzymatic antioxidant system, oxidative burdens, microgliosis, and pro-apoptotic changes led to the dopaminergic neurotoxicity. Neuroprotective effects of GRe were more pronounced in prodynorphin knockout than in WT mice. Nor-binaltorphimine, a kappa-opioid receptor antagonist, counteracted against protective effects of GRe. In addition, we found that GRe significantly attenuated MA-induced increases in substance P immunoreactivity and substance P mRNA expression in the substantia nigra. These increases were more evident in prodynorphin knockout than in WT mice. Although, we observed that substance P-immunoreactivity was co-localized in NeuN immunreactive neurons, GFAP-immunoreactive astrocytes, and Iba-1-immunoreactive microglia. NK1 receptor antagonist L-733,060 or GRe selectively inhibited microgliosis induced by MA. Furthermore, L-733,060 did not show any additive effects against GRe-mediated protective activity (i.e., antioxidant, antimicroglial, and antiapoptotic effects), indicating that NK1 receptor is one of the molecular targets of GRe. CONCLUSIONS: Our results suggest that GRe protects MA-induced dopaminergic neurotoxicity via upregulatgion of dynorphin mediated kappa-opioid receptor and downregulation of substance P-mediated NK1 R. PMID- 29467001 TI - Neuregulin-1 elicits a regulatory immune response following traumatic spinal cord injury. AB - BACKGROUND: Spinal cord injury (SCI) triggers a robust neuroinflammatory response that governs secondary injury mechanisms with both degenerative and pro regenerative effects. Identifying new immunomodulatory therapies to promote the supportive aspect of immune response is critically needed for the treatment of SCI. We previously demonstrated that SCI results in acute and permanent depletion of the neuronally derived Neuregulin-1 (Nrg-1) in the spinal cord. Increasing the dysregulated level of Nrg-1 through acute intrathecal Nrg-1 treatment enhanced endogenous cell replacement and promoted white matter preservation and functional recovery in rat SCI. Moreover, we identified a neuroprotective role for Nrg-1 in moderating the activity of resident astrocytes and microglia following injury. To date, the impact of Nrg-1 on immune response in SCI has not yet been investigated. In this study, we elucidated the effect of systemic Nrg-1 therapy on the recruitment and function of macrophages, T cells, and B cells, three major leukocyte populations involved in neuroinflammatory processes following SCI. METHODS: We utilized a clinically relevant model of moderately severe compressive SCI in female Sprague-Dawley rats. Nrg-1 (2 MUg/day) or saline was delivered subcutaneously through osmotic mini-pumps starting 30 min after SCI. We conducted flow cytometry, quantitative real-time PCR, and immunohistochemistry at acute, subacute, and chronic stages of SCI to investigate the effects of Nrg-1 treatment on systemic and spinal cord immune response as well as cytokine, chemokine, and antibody production. RESULTS: We provide novel evidence that Nrg-1 promotes a pro regenerative immune response after SCI. Bioavailability of Nrg-1 stimulated a regulatory phenotype in T and B cells and augmented the population of M2 macrophages in the spinal cord and blood during the acute and chronic stages of SCI. Importantly, Nrg-1 fostered a more balanced microenvironment in the injured spinal cord by attenuating antibody deposition and expression of pro-inflammatory cytokines and chemokines while upregulating pro-regenerative mediators. CONCLUSION: We provide the first evidence of a significant regulatory role for Nrg-1 in neuroinflammation after SCI. Importantly, the present study establishes the promise of systemic Nrg-1 treatment as a candidate immunotherapy for traumatic SCI and other CNS neuroinflammatory conditions. PMID- 29467002 TI - Intraocular DHODH-inhibitor PP-001 suppresses relapsing experimental uveitis and cytokine production of human lymphocytes, but not of RPE cells. AB - BACKGROUND: Uveitis is a potentially blinding inflammatory disease of the inner eye with a high unmet need for new therapeutic interventions. Here, we wanted to investigate the suppressive effect of the intraocular application of the small molecule dihydroorotate dehydrogenase (DHODH)-inhibitor PP-001 on experimental relapsing rat uveitis and furthermore determine its effect on proliferation and cytokine secretion of human peripheral blood lymphocytes (PBL) and human retinal pigment epithelial (RPE) cells in vitro. METHODS: Spontaneously relapsing uveitis was induced in rats by immunization with interphotoreceptor retinoid-binding protein (IRBP) peptide R14. PP-001 was injected intravitreally after resolution of the primary disease to investigate further relapses. Proliferation and metabolic activity of phytohemagglutinin (PHA)-stimulated human peripheral lymphocytes with and without PP-001 and cytokine secretion were determined by XTT assay and bioplex bead assay. The RPE cell line ARPE-19 as well as primary human RPE cells treated with PP-001 or anti-vascular endothelial growth factor (VEGF) antibody bevacizumab were also investigated for metabolic activity and cytokine/chemokine secretion. RESULTS: Injection of PP-001 into rat eyes reduced the number of relapses by 70%, from 20 relapses (57% of the rats affected) in the control group to 6 relapses (33% of the rats) in the treatment group. In human PBL cultures, PP-001 reduced the proliferation in a dose-dependent manner. The secretion of several cytokines such as IL-17, IFN-gamma, and VEGF was suppressed by PP-001, as previously observed with rat T cells in the experimental autoimmune uveitis (EAU) model. In contrast, human RPE cells were not affected by PP-001, while the anti-VEGF antibody bevacizumab severely impaired the secretion of various cytokines including VEGF. CONCLUSIONS: For the first time, intravitreal injection of PP-001 demonstrated an effective, but transient reduction of relapses in the rat EAU model. In vitro PP-001 suppressed proliferation and cytokine/chemokine secretion of human lymphocytes, while neither human RPE cell line ARPE-19 nor primary RPE cells were affected. PMID- 29467003 TI - Extracellular alpha-synuclein levels are regulated by neuronal activity. AB - BACKGROUND: alpha-Synuclein is a presynaptic protein abundant in the cytoplasmic compartment of neurons, whereas its presence in the extracellular space has also been observed under physiological conditions. Extracellular alpha-synuclein has pathological significance, exhibiting cellular toxicity and impairment of synaptic transmission. Notably, misfolded alpha-synuclein drives the cell-to-cell propagation of pathology via the extracellular space. However, the primary mechanism that regulates the extracellular levels of alpha-synuclein remains to be determined. METHODS: Using several mechanistically distinct methods to modulate neuronal/synaptic activities in primary neuronal culture and in vivo microdialysis, we examined the involvement of neuronal/synaptic activities on alpha-synuclein release. RESULTS: We demonstrate here that physiological release of endogenous alpha-synuclein highly depends on intrinsic neuronal activities. Elevating neuronal activity rapidly increased, while blocking activity decreased, alpha-synuclein release. In vivo microdialysis experiments in freely moving mice revealed that ~ 70% of extracellular alpha-synuclein arises from neuronal activity-dependent pathway. Selective modulation of glutamatergic neurotransmission altered extracellular alpha-synuclein levels, implicating this specific neuronal network in the mechanism of activity-dependent release of alpha synuclein. While neuronal activity tightly regulated alpha-synuclein release, elevated synaptic vesicle exocytosis per se was capable to elicit alpha-synuclein release. We also found that extracellular alpha-synuclein exists as high molecular weight species. CONCLUSIONS: The present study uncovers a novel regulatory pathway associated with alpha-synuclein release, whose dysregulation might affect various pathological actions of extracellular alpha-synuclein including its trans-synaptic propagation. PMID- 29467004 TI - Orf virus infection in Alaskan mountain goats, Dall's sheep, muskoxen, caribou and Sitka black-tailed deer. AB - BACKGROUND: The zoonotic Orf virus (ORFV; genus Parapoxvirus, Poxviridae family) occurs worldwide and is transmitted between sheep and goats, wildlife and man. Archived tissue samples from 16 Alaskan wildlife cases, representing mountain goat (Oreamnos americanus, n = 8), Dall's sheep (Ovis dalli dalli, n = 3), muskox (Ovibos moschatus, n = 3), Sitka black-tailed deer (Odocoileus hemionus sitkensis, n = 1) and caribou (Rangifer tarandus granti, n = 1), were analyzed. RESULTS: Clinical signs and pathology were most severe in mountain goats, affecting most mucocutaneous regions, including palpebrae, nares, lips, anus, prepuce or vulva, as well as coronary bands. The proliferative masses were solid and nodular, covered by dark friable crusts. For Dall's sheep lambs and juveniles, the gross lesions were similar to those of mountain goats, but not as extensive. The muskoxen displayed ulcerative lesions on the legs. The caribou had two ulcerative lesions on the upper lip, as well as lesions on the distal part of the legs, around the main and dew claws. A large hairless spherical mass, with the characteristics of a fibroma, was sampled from a Sitka black-tailed deer, which did not show proliferative lesions typical of an ORFV infection. Polymerase chain reaction analyses for B2L, GIF, vIL-10 and ATI demonstrated ORFV specific DNA in all cases. Sequences from Dall's sheep formed a separate cluster, comparable to ORFV from domestic sheep. Sequences from the other species were different from the Dall's sheep sequences, but almost identical to each other. CONCLUSIONS: This is the first major investigation of parapoxvirus infections in large Alaskan game species, and the first report of parapoxvirus infection in caribou and Sitka black-tailed deer. This study shows that most of the wild ruminant species in Alaska and from most parts of Alaska, can carry and be affected by ORFV. These findings call for attention to transmission of ORFV from wildlife to livestock and to hunters, subsistence harvesters, and wildlife biologists. PMID- 29467005 TI - Traditional knowledge on herbal drinks among indigenous communities in Azad Jammu and Kashmir, Pakistan. AB - BACKGROUND: Traditional knowledge about the use of medicinal plants for herbal drinks (HDs) is not well documented in the Azad Kashmir region despite their widespread use. This study highlights the taxonomic diversity and traditional knowledge on medicinal plants used for HDs while examining the diversity of diseases treated with HDs in the study area. METHODS: Individual discussions were conducted with 255 informants (84 women and 171 men). Data gathered included (i) informant age and gender, (ii) HD species and respective plant parts used, (iii) health disorders treated, and (iv) mode of preparation and utilizations. Quantitative ethnobotanical indices including relative frequency of citation (RFC), informant consensus factor (ICF), and use value (UV) were used for data analyses. RESULTS: Altogether, 73 medicinal plants belonging to 40 families and 66 genera were reported to be used in HD preparations, with Asteraceae being the richest family. The average number of HD species cited was 9.09 +/- 0.17 per informant and did not vary either by age or gender. In addition, men and women, and adults and the young used the same pool of species (dissimilarity nearly zero). The most used plant parts were leaves (20.00%), roots (17.25%), and fruits (16.47%). Based on UV, the top five most used species were Valeriana jatamansi, Isodon rugosus, Onopordum acanthium, Acacia nilotica, and Viola canescens; and the UV was similar among gender and age categories too. The most utilized herbal preparation forms included decoctions, infusions, and tea. One hundred and eleven diseases grouped into 13 ailment categories were reported to be cured using HDs. The main category of disease treated with HDs was gastrointestinal (GIT) disorders (RFC = 17.43%). Relatively few species were used by a large proportion of informants for each category of ailment (ICF >= 0.60). Only one species was used for "glandular disorders" and "eye diseases" (ICF = 1). A novelty of about 22% (16 species) was recorded for HD species in the present work. CONCLUSION: The diversity of medicinal plant species used as HDs and the associated traditional knowledge are of considerable value to the indigenous communities of the Azad Kashmir region. Therefore, there is a need for conservation and preservation of medicinal HD species as well as the wealth of indigenous knowledge. The conservation effort should be high for species in the ailments categories glandular disorders and eye diseases. The therapeutic uses of HDs have provided basic data for further research focused on phytochemical and pharmacological studies and conservation of the most important species. PMID- 29467006 TI - Associations within school-based same-sex friendship networks of children's physical activity and sedentary behaviours: a cross-sectional social network analysis. AB - BACKGROUND: Physical activity in children is associated with better physical and mental health but many children do not meet physical activity guidelines. Friendship groups are potentially an important influence on children's physical activity and sedentary time. This paper examines the association between children of physical activity and sedentary time in school-based same-sex friendship networks, for both moderate-to-vigorous intensity physical activity (MVPA) and sedentary time. Moreover, considering the methodological challenges of conducting and interpreting these analyses, we provide examples of how to analyse these data and interpret results to encourage further work in the area. METHODS: Accelerometer data for 1223 children, aged 8-9 years, were collected in 2015-2016 and analysed in 2017. Mean accelerometer minutes of MVPA and sedentary time were calculated. Children named up to four school friends and same-sex school-based friendship networks were constructed. Network models, which include correlation between friends, were fitted by sex. RESULTS: Both MVPA and sedentary time were found to be associated via the friendship networks, for both boys and girls. The network autocorrelation was 0.21 (95% CI: 0.15 to 0.26) for boys' MVPA, and 0.14 (95% CI: 0.07 to 0.21) for sedentary time. Network autocorrelation between girls was weaker, with 0.13 (95% CI: 0.06 to 0.19) for MVPA and 0.11 (95% CI: 0.05 to 0.17) for sedentary time. CONCLUSIONS: Physical activity and sedentary time of boys and girls are associated with the physical activity and sedentary time respectively of others within same-sex friendship networks, and these associations are comparable to other known factors. In this study, the correlation between friends was stronger for boys than girls, and stronger for MVPA than for sedentary time. These findings suggest that friendship networks play a part in understanding children's physical activity and sedentary time and could play a valuable role in developing effective interventions. PMID- 29467007 TI - Enhanced glycolysis contributes to the pathogenesis of experimental autoimmune neuritis. AB - BACKGROUND: With the recognition of the key roles of cellular metabolism in immunity, targeting metabolic pathway becomes a new strategy for autoimmune disease treatment. Guillain-Barre syndrome (GBS) is an acute immune-mediated inflammatory demyelinating disease of the peripheral nervous system, characterized by inflammatory cell infiltration. These inflammatory cells, including activated macrophages, Th1 cells, and Th17 cells, generally undergo metabolic reprogramming and rely mainly on glycolysis to exert functions. This study aimed to explore whether enhanced glycolysis contributed to the pathogenesis of experimental autoimmune neuritis (EAN), a classic model of GBS. METHODS: Preventive and therapeutic treatments with glycolysis inhibitor, 2-deoxy D-glucose (2-DG), were applied to EAN rats. The effects of treatments were determined by clinical scoring, weighting, and tissue examination. Flow cytometry and ELISA were used to evaluate T cell differentiation, autoantibody level, and macrophage functions in vivo and in vitro. RESULTS: Glycolysis inhibition with 2 DG not only inhibited the initiation, but also prevented the progression of EAN, evidenced by the improved clinical scores, weight loss, inflammatory cell infiltration, and demyelination of sciatic nerves. 2-DG inhibited the differentiation of Th1, Th17, and Tfh cells but enhanced Treg cell development, accompanied with reduced autoantibody secretion. Further experiments in vitro proved glycolysis inhibition decreased the nitric oxide production and phagocytosis of macrophages and suppressed the maturation of dendritic cells (DC). CONCLUSION: The effects of glycolysis inhibition on both innate and adaptive immune responses and the alleviation of animal clinical symptoms indicated that enhanced glycolysis contributed to the pathogenesis of EAN. Glycolysis inhibition may be a new therapy for GBS. PMID- 29467009 TI - Mesalazine-induced myocarditis: a case report. AB - BACKGROUND: Myocarditis is a rare complication of therapy with mesalazine, a drug widely prescribed in the treatment of inflammatory bowel disease. CASE PRESENTATION: We report a case of myocarditis occurring in a 49-year-old British man 10 days following initiation of mesalazine therapy for treatment of ulcerative colitis. He presented with troponin-positive chest pain, and the diagnosis of myocarditis was confirmed on the basis of cardiac magnetic resonance imaging, which showed subepicardial delayed gadolinium enhancement in the basal to middle inferior and inferolateral segments of the heart. The patient's symptoms and condition improved upon stopping mesalazine, and he made a full recovery. CONCLUSIONS: Mesalazine-induced myocarditis may be more common than first appreciated and is potentially fatal. Therefore, it is imperative that clinicians be aware of this potentially life-threatening adverse effect of mesalazine therapy and warn patients to seek urgent medical attention if cardiac symptoms arise. PMID- 29467008 TI - Interventions to prevent hemodynamic instability during renal replacement therapy in critically ill patients: a systematic review. AB - BACKGROUND: Hemodynamic instability related to renal replacement therapy (HIRRT) may increase the risk of death and limit renal recovery. Studies in end-stage renal disease populations on maintenance hemodialysis suggest that some renal replacement therapy (RRT)-related interventions (e.g., cool dialysate) may reduce the occurrence of HIRRT, but less is known about interventions to prevent HIRRT in critically ill patients receiving RRT for acute kidney injury (AKI). We sought to evaluate the effectiveness of RRT-related interventions for reducing HIRRT in such patients across RRT modalities. METHODS: A systematic review of publications was undertaken using MEDLINE, MEDLINE in Process, EMBASE, and Cochrane's Central Registry for Randomized Controlled Trials (RCTs). Studies that assessed any intervention's effect on HIRRT (the primary outcome) in critically ill patients with AKI were included. HIRRT was variably defined according to each study's definition. Two reviewers independently screened abstracts, identified articles for inclusion, extracted data, and evaluated study quality using validated assessment tools. RESULTS: Five RCTs and four observational studies were included (n = 9; 623 patients in total). Studies were small, and the quality was mostly low. Interventions included dialysate sodium modeling (n = 3), ultrafiltration profiling (n = 2), blood volume (n = 2) and temperature control (n = 3), duration of RRT (n = 1), and slow blood flow rate at initiation (n = 1). Some studies applied more than one strategy simultaneously (n = 5). Interventions shown to reduce HIRRT from three studies (two RCTs and one observational study) included higher dialysate sodium concentration, lower dialysate temperature, variable ultrafiltration rates, or a combination of strategies. Interventions not found to have an effect included blood volume and temperature control, extended duration of intermittent RRT, and slower blood flow rates during continuous RRT initiation. How HIRRT was defined and its frequency of occurrence varied widely across studies, including those involving the same RRT modality. Pooled analysis was not possible due to study heterogeneity. CONCLUSIONS: Small clinical studies suggest that higher dialysate sodium, lower temperature, individualized ultrafiltration rates, or a combination of these strategies may reduce the risk of HIRRT. Overall, for all RRT modalities, there is a paucity of high-quality data regarding interventions to reduce the occurrence of HIRRT in critically ill patients.

AB - BACKGROUND: A keloid is a fibroproliferative disorder occurring in wounds characterized by an exaggerated response to injury. To date, no effective cure has been identified. As multipotent stem cells, human adipose-derived stem cells (ADSCs) may show the possibility for curing diseases such as fibrosis. This study sought to explore the potential role of human ADSCs in curing keloids. METHODS: After culture in conditioned medium, gene and protein expression of keloid fibroblasts was examined using real-time polymerase chain reaction (RT-PCR) and Western blotting, while analysis of the cell cycle was used to measure the proliferative properties of the cells. Furthermore, ex vivo explant cultures were used to test the effects of ADSC-conditioned medium (ADSC-CM) on CD31+ and CD34+ expression in keloid tissue. RESULTS: Our experimental results show that ADSC-CM was able to attenuate extracellular matrix-related gene expression as well as decrease protein expression. Cell proliferation was significantly suppressed in our study. CD31+ and CD34+ vessels in ex vivo explants were reduced by 55% and 57% in treatment groups compared with control groups. CONCLUSIONS: Human ADSC-CM significantly inhibited keloid fibroblast-related bioactivities. PMID- 29467011 TI - Genes sharing the protein family domain decrease the performance of classification with RNA-seq genomic signatures. AB - BACKGROUND: The experience with running various types of classification on the CAMDA neuroblastoma dataset have led us to the conclusion that the results are not always obvious and may differ depending on type of analysis and selection of genes used for classification. This paper aims in pointing out several factors that may influence the downstream machine learning analysis. In particular those factors are: type of the primary analysis, type of the classifier and increased correlation between the genes sharing a protein domain. They influence the analysis directly, but also interplay between them may be important. We have compiled the gene-domain database and used it for analysis to see the differences between the genes that share a domain versus the rest of the genes in the datasets. RESULTS: The major findings are: pairs of genes that share a domain have an increased Spearman's correlation coefficients of counts; genes sharing a domain are expected to have a lower predictive power due to increased correlation. For most of the cases it can be seen with the higher number of misclassified samples; classifiers performance may vary depending on a method, still in most cases using genes sharing a domain in the training set results in a higher misclassification rate; increased correlation in genes sharing a domain results most often in worse performance of the classifiers regardless of the primary analysis tools used, even if the primary analysis alignment yield varies. CONCLUSIONS: The effect of sharing a domain is likely more a results of real biological co-expression than just sequence similarity and artifacts of mapping and counting. Still, this is more difficult to conclude and needs further research. The effect is interesting itself, but we also point out some practical aspects in which it may influence the RNA sequencing analysis and RNA biomarker use. In particular it means that a gene signature biomarker set build out of RNA sequencing results should be depleted for genes sharing common domains. It may cause to perform better when applying classification. REVIEWERS: This article was reviewed by Dimitar Vassiliev and Susmita Datta. PMID- 29467012 TI - Structural and advanced imaging in predicting MGMT promoter methylation of primary glioblastoma: a region of interest based analysis. AB - BACKGROUND: The methylation status of oxygen 6-methylguanine-DNA methyltransferase (MGMT) promoter has been associated with treatment response in glioblastoma(GBM). Using pre-operative MRI techniques to predict MGMT promoter methylation status remains inconclusive. In this study, we investigated the value of features from structural and advanced imagings in predicting the methylation of MGMT promoter in primary glioblastoma patients. METHODS: Ninety-two pathologically confirmed primary glioblastoma patients underwent preoperative structural MR imagings and the efficacy of structural image features were qualitatively analyzed using Fisher's exact test. In addition, 77 of the 92 patients underwent additional advanced MRI scans including diffusion-weighted (DWI) and 3-diminsional pseudo-continuous arterial spin labeling (3D pCASL) imaging. Apparent diffusion coefficient (ADC) and relative cerebral blood flow (rCBF) values within the manually drawn region-of-interest (ROI) were calculated and compared using independent sample t test for their efficacies in predicting MGMT promoter methylation. Receiver operating characteristic curve (ROC) analysis was used to investigate the predicting efficacy with the area under the curve (AUC) and cross validations. Multiple-variable logistic regression model was employed to evaluate the predicting performance of multiple variables. RESULTS: MGMT promoter methylation was associated with tumor location and necrosis (P < 0.05). Significantly increased ADC value (P < 0.001) and decreased rCBF (P < 0.001) were associated with MGMT promoter methylation in primary glioblastoma. The ADC achieved the better predicting efficacy than rCBF (ADC: AUC, 0.860; sensitivity, 81.1%; specificity, 82.5%; vs rCBF: AUC, 0.835; sensitivity, 75.0%; specificity, 78.4%; P = 0.032). The combination of tumor location, necrosis, ADC and rCBF resulted in the highest AUC of 0.914. CONCLUSION: ADC and rCBF are promising imaging biomarkers in clinical routine to predict the MGMT promoter methylation in primary glioblastoma patients. PMID- 29467013 TI - Description of complex interventions: analysis of changes in reporting in randomised trials since 2002. AB - BACKGROUND: Inadequate description of non-pharmacological complex interventions in trial publications means that they cannot be replicated or assessed for generalisability. There are published guidelines on how to describe an intervention, such as those from the CONSORT Group. However, there have been few evaluations of whether intervention reporting is improving. METHODS: We aimed to assess whether descriptions of multicomponent, non-pharmacological interventions evaluated in randomised trials are improving. To do so, we chose trials of educational and psychotherapeutic interventions to promote adherence to therapy, and compared those published between 2002 and 2007 (Time-1) with those between 2010 and 2015 (Time-2). These time periods were chosen to concord with the publication in 2008 of the CONSORT extension statement of reporting guidelines for non-pharmacological treatment which included items on intervention description. We assessed 19 items, based on the CONSORT Statement and the more recent Template for Intervention Description and Replication Checklist (TIDieR). Two reviewers independently extracted data. We created a quality score of the eight items we considered key information for replication and assessment of generalisability (setting, provider, recipient, comparator, intervention intensity, how it was conducted, existence of a manual or protocol, and detail of whether there was an assessment of fidelity). Score per item was '1' if reported adequately and '0' if not. RESULTS: Of the eligible trials, 42 were published in Time-1 and 134 published in Time-2. The trials included were published in 112 peer-reviewed journals, 52 of these journals currently require authors to follow the CONSORT Statements, while only one recommended adherence to the TIDieR. Most items of CONSORT and TIDieR were reported by more than half of the trials at both time points. Few trials reported fidelity. A large proportion of the trials did not report the existence of a manual or protocol, or what the comparator group received. We found no statistically significant improvement in the eight-item quality score (Time-1: mean 5.71 (standard deviation (SD) 1.09), Time-2: 5.87 (SD 1.28), p = 0.49). CONCLUSIONS: We found no overall evidence that reporting the specifics of multicomponent, non-pharmacological interventions is improving. Details to replicate interventions remain lacking, impairing best implementation or meaningful further research. Editorial endorsement of reporting checklists needs to be more extensive. PMID- 29467014 TI - A biomaterials approach to influence stem cell fate in injectable cell-based therapies. AB - BACKGROUND: Numerous stem cell therapies use injection-based administration to deliver high-density cell preparations. However, cell retention rates as low as 1% have been observed within days of transplantation. This study investigated the effects of varying administration and formulation parameters of injection-based administration on cell dose recovery and differentiation fate choice of human mesenchymal stem cells. METHODS: The impact of ejection rate via clinically relevant Hamilton micro-syringes and biomaterial-assisted delivery was investigated. Cell viability, the percentage of cell dose delivered as viable cells, proliferation capacity as well as differentiation behaviour in bipotential media were assessed. Characterisation of the biomaterial-based cell carriers was also carried out. RESULTS: A significant improvement of in-vitro dose recovery in cells co-ejected with natural biomaterials was observed, with ejections within 2% (w/v) gelatin resulting in 87.5 +/- 14% of the cell dose being delivered as viable cells, compared to 32.2 +/- 19% of the dose ejected in the commonly used saline vehicle at 10 MUl/min. Improvement in cell recovery was not associated with the rheological properties of biomaterials utilised, as suggested by previous studies. The extent of osteogenic differentiation was shown to be substantially altered by choice of ejection rate and cell carrier, despite limited contact time with cells during ejection. Collagen type I and bone-derived extracellular matrix cell carriers yielded significant increases in mineralised matrix deposited at day 21 relative to PBS. CONCLUSIONS: An enhanced understanding of how administration protocols and biomaterials influence cell recovery, differentiation capacity and choice of fate will facilitate the development of improved administration and formulation approaches to achieve higher efficacy in stem cell transplantation. PMID- 29467015 TI - Prevention of disease progression in Leishmania infantum-infected dogs with dietary nucleotides and active hexose correlated compound. AB - BACKGROUND: The prevalence of Leishmania infantum infection in clinically healthy dogs can be several times higher than that of clinical disease in endemic areas. Although treatment is not recommended in dogs with subclinical infection, these animals should be managed to prevent disease progression and parasite transmission to human beings or to other dogs. Dietary nucleotides and active hexose correlated compound (AHCC) have been shown to modulate the immune response. A recent study in dogs with clinical leishmaniosis receiving an initial 28-day course of methylglucamine antimoniate showed that six-month administration of a dietary supplement containing nucleotides plus AHCC achieves similar efficacy to allopurinol. Since the type of immune response plays a key role in the evolution of patients with leishmaniosis, the present study was aimed at evaluating the preventive effect of this supplement in avoiding or delaying disease progression in clinically healthy Leishmania-infected dogs. METHODS: Forty-six dogs were included in this multicenter, randomized, double-blind, placebo-controlled trial. Dogs received once-daily oral administration of a placebo or a dietary supplement containing nucleotides plus AHCC. Disease progression was monitored throughout the study in both groups. At 0, 60, 180 and 365 days of treatment, clinical signs were evaluated using a validated clinical scoring system, and several analytes were measured from blood, urine, and bone marrow samples. RESULTS: During the study, a significantly lower (P = 0.047) proportion of dogs changed their clinical status and became sick in the supplement group (3/20; 15%), compared to the placebo group (10/22; 45.5%). ELISA determined antibody titers were significantly reduced compared to baseline at all time points with the supplement (P < 0.01), but not with the placebo. The mean clinical score of disease severity was significantly lower in the supplement group after 180 days (P = 0.014). No significant differences were observed for the other parameters. The dietary supplement was well tolerated. CONCLUSIONS: Oral administration of nucleotides plus AHCC for 365 days in clinically healthy L. infantum-infected dogs is safe, allows a significant reduction in anti Leishmania antibodies, and leads to a lower disease progression rate, hence exerting a preventive effect. PMID- 29467016 TI - Advancing osteochondral tissue engineering: bone morphogenetic protein, transforming growth factor, and fibroblast growth factor signaling drive ordered differentiation of periosteal cells resulting in stable cartilage and bone formation in vivo. AB - BACKGROUND: Chondrogenic mesenchymal stem cells (MSCs) have not yet been used to address the clinical demands of large osteochondral joint surface defects. In this study, self-assembling tissue intermediates (TIs) derived from human periosteum-derived stem/progenitor cells (hPDCs) were generated and validated for stable cartilage formation in vivo using two different animal models. METHODS: hPDCs were aggregated and cultured in the presence of a novel growth factor (GF) cocktail comprising of transforming growth factor (TGF)-beta1, bone morphogenetic protein (BMP)2, growth differentiation factor (GDF)5, BMP6, and fibroblast growth factor (FGF)2. Quantitative polymerase chain reaction (PCR) and immunohistochemistry were used to study in vitro differentiation. Aggregates were then implanted ectopically in nude mice and orthotopically in critical-size osteochondral defects in nude rats and evaluated by microcomputed tomography (uCT) and immunohistochemistry. RESULTS: Gene expression analysis after 28 days of in vitro culture revealed the expression of early and late chondrogenic markers and a significant upregulation of NOGGIN as compared to human articular chondrocytes (hACs). Histological examination revealed a bilayered structure comprising of chondrocytes at different stages of maturity. Ectopically, TIs generated both bone and mineralized cartilage at 8 weeks after implantation. Osteochondral defects treated with TIs displayed glycosaminoglycan (GAG) production, type-II collagen, and lubricin expression. Immunostaining for human nuclei protein suggested that hPDCs contributed to both subchondral bone and articular cartilage repair. CONCLUSION: Our data indicate that in vitro derived osteochondral-like tissues can be generated from hPDCs, which are capable of producing bone and cartilage ectopically and behave orthotopically as osteochondral units. PMID- 29467017 TI - ADJunctive Ulinastatin in Sepsis Treatment in China (ADJUST study): study protocol for a randomized controlled trial. AB - BACKGROUND: Sepsis is a major challenge in critical care and is associated with high mortality. Current management of sepsis and septic shock remains mainly supportive. Both basic and clinical research has shown that ulinastatin can improve the prognosis of sepsis. The aim of this trial is to evaluate the efficacy and safety profiles of ulinastatin compared with placebo. METHODS/DESIGN: In this multi-center, double-blind, randomized placebo-controlled trial we are recruiting a total of 348 subjects meeting "The Third International Consensus Definitions for Sepsis and Septic Shock" (Sepsis-3). Subjects will be randomized (1:1) to receive ulinastatin 400,000 IU three times a day for 10 days or matching placebo and usual care simultaneously. The primary outcome is 28-day all-cause mortality. Adverse events and serious adverse events will be monitored closely. DISCUSSION: ADJUST is a large, multi-center, double-blind, randomized, parallel-group, placebo-controlled trial of ulinastatin in mainland China and is well-designed on the basis of previous studies. The results of this trial may help to provide evidence-based recommendations for treatment of sepsis. TRIAL REGISTRATION: ClinicalTrials.gov, ID: NCT02647554 .

PMID- 29467018 TI - Efficacy of different DNA and MVA prime-boost vaccination regimens against a Rift Valley fever virus (RVFV) challenge in sheep 12 weeks following vaccination. AB - The aim of this work was to evaluate the immunogenicity and efficacy of DNA and MVA vaccines encoding the RVFV glycoproteins Gn and Gc in an ovine model of RVFV infection. Adult sheep of both sexes were challenged 12 weeks after the last immunization and clinical, virological, biochemical and immunological consequences, were analyzed. Strategies based on immunization with homologous DNA or heterologous DNA/MVA prime-boost were able to induce a rapid in vitro neutralizing antibody response as well as IFNgamma production after in vitro virus specific re-stimulation. In these animals we observed reduced viremia levels and less clinical signs when compared with mock-immunized controls. In contrast, sheep inoculated with a homologous MVA prime-boost showed increased viremia correlating with the absence of detectable neutralizing antibody responses, despite of inducing cellular responses after the last immunization. However, faster induction of neutralizing antibodies and IFNgamma production after challenge were found in this group when compared to the mock vaccinated group, indicative of a primed immune response. In conclusion, these results suggest that vaccination strategies based on DNA priming were able to mount and maintain specific anti-RVFV glycoprotein immune responses upon homologous or heterologous booster doses, warranting further optimization in large animal models of infection. PMID- 29467020 TI - Insulin-like growth factor-1-mediated regulation of miR-193a expression promotes the migration and proliferation of c-kit-positive mouse cardiac stem cells. AB - BACKGROUND: C-kit-positive cardiac stem cells (CSCs) have been shown to be a promising candidate treatment for myocardial infarction and heart failure. Insulin-like growth factor (IGF)-1 is an anabolic growth hormone that regulates cellular proliferation, differentiation, senescence, and death in various tissues. Although IGF-1 promotes the migration and proliferation of c-kit positive mouse CSCs, the underlying mechanism remains unclear. METHODS: Cells were isolated from adult mouse hearts, and c-kit-positive CSCs were separated using magnetic beads. The cells were cultured with or without IGF-1, and c-kit expression was measured by Western blotting. IGF-1 induced CSC proliferation and migration, as measured through Cell Counting Kit-8 (CCK-8) and Transwell assays, respectively. The miR-193a expression was measured by quantitative real-time PCR (qPCR) assays. RESULTS: IGF-1 enhanced c-kit expression in c-kit-positive CSCs. The activities of the phosphoinositol 3-kinase (PI3K)/AKT signaling pathway and DNA methyltransferases (DNMTs) were enhanced, and their respective inhibitors LY294002 and 5-azacytidine (5-AZA) blunted c-kit expression. Based on the results of quantitative real-time PCR (qPCR) assays, the expression of miR-193a, which is embedded in a CpG island, was down-regulated in the IGF-1-stimulated group and negatively correlated with c-kit expression, whereas c-kit-positive CSCs infected with lentivirus carrying micro-RNA193a displayed reduced c-kit expression, migration and proliferation. CONCLUSIONS: IGF-1 upregulated c-kit expression in c kit-positive CSCs resulting in enhanced CSC proliferation and migration by activating the PI3K/AKT/DNMT signaling pathway to epigenetically silence miR 193a, which negatively modifies the c-kit expression level. PMID- 29467019 TI - Clinical- and cost-effectiveness of the STAR care pathway compared to usual care for patients with chronic pain after total knee replacement: study protocol for a UK randomised controlled trial. AB - BACKGROUND: Approximately 20% of patients experience chronic pain after total knee replacement. There is little evidence for effective interventions for the management of this pain, and current healthcare provision is patchy and inconsistent. Given the complexity of this condition, multimodal and individualised interventions matched to pain characteristics are needed. We have undertaken a comprehensive programme of work to develop a care pathway for patients with chronic pain after total knee replacement. This protocol describes the design of a randomised controlled trial to evaluate the clinical- and cost effectiveness of a complex intervention care pathway compared with usual care. METHODS: This is a pragmatic two-armed, open, multi-centred randomised controlled trial conducted within secondary care in the UK. Patients will be screened at 2 months after total knee replacement and 381 patients with chronic pain at 3 months postoperatively will be recruited. Recruitment processes will be optimised through qualitative research during a 6-month internal pilot phase. Patients are randomised using a 2:1 intervention:control allocation ratio. All participants receive usual care as provided by their hospital. The intervention comprises an assessment clinic appointment at 3 months postoperatively with an Extended Scope Practitioner and up to six telephone follow-up calls over 12 months. In the assessment clinic, a standardised protocol is followed to identify potential underlying causes for the chronic pain and enable appropriate onward referrals to existing services for targeted and individualised treatment. Outcomes are assessed by questionnaires at 6 and 12 months after randomisation. The co-primary outcomes are pain severity and pain interference assessed using the Brief Pain Inventory at 12 months after randomisation. Secondary outcomes relate to resource use, function, neuropathic pain, mental well-being, use of pain medications, satisfaction with pain relief, pain frequency, capability, health-related quality of life and bodily pain. After trial completion, up to 30 patients in the intervention group will be interviewed about their experiences of the care pathway. DISCUSSION: If shown to be clinically and cost-effective, this care pathway intervention could improve the management of chronic pain after total knee replacement.

PMID- 29467021 TI - Conjunctival transcriptome profiling of Solomon Islanders with active trachoma in the absence of Chlamydia trachomatis infection. AB - BACKGROUND: Clinical signs of active (inflammatory) trachoma are found in many children in the Solomon Islands, but the majority of these individuals have no serological evidence of previous infection with Chlamydia trachomatis. In Temotu and Rennell and Bellona provinces, ocular infections with C. trachomatis were seldom detected among children with active trachoma; a similar lack of association was seen between active trachoma and other common bacterial and viral causes of follicular conjunctivitis. Here, we set out to characterise patterns of gene expression at the conjunctivae of children in these provinces with and without clinical signs of trachomatous inflammation-follicular (TF) and C. trachomatis infection. METHODS: Purified RNA from children with and without active trachoma was run on Affymetrix GeneChip Human Transcriptome Array 2.0 microarrays. Profiles were compared between individuals with ocular C. trachomatis infection and TF (group DI; n = 6), individuals with TF but no C. trachomatis infection (group D; n = 7), and individuals without TF or C. trachomatis infection (group N; n = 7). Differential gene expression and gene set enrichment for pathway membership were assessed. RESULTS: Conjunctival gene expression profiles were more similar within-group than between-group. Principal components analysis indicated that the first and second principal components combined explained almost 50% of the variance in the dataset. When comparing the DI group to the N group, genes involved in T-cell proliferation, B-cell signalling and CD8+ T cell signalling pathways were differentially regulated. When comparing the DI group to the D group, CD8+ T-cell regulation, interferon gamma and IL17 production pathways were enriched. Genes involved in RNA transcription and translation pathways were upregulated when comparing the D group to the N group. CONCLUSIONS: Gene expression profiles in children in the Solomon Islands indicate immune responses consistent with bacterial infection when TF and C. trachomatis infection are concurrent. The transcriptomes of children with TF but without identified infection were not consistent with allergic or viral conjunctivitis. PMID- 29467022 TI - Recovery of muscle function after deep neuromuscular block by means of diaphragm ultrasonography and adductor of pollicis acceleromyography with comparison of neostigmine vs. sugammadex as reversal drugs: study protocol for a randomized controlled trial. AB - BACKGROUND: The extensive use of neuromuscular blocking agents (NMBAs) during surgical procedures still leads to potential residual paralyzing effects in the postoperative period. Indeed, neuromuscular monitoring in an intra-operative setting is strongly advocated. Acetylcholinesterase inhibitors can reverse muscle block, but their short half-life may lead to residual curarization in the ward, especially when intermediate or long-acting NMBAs have been administered. Sugammadex is the first selective reversal drug for steroidal NMBAs; it has been shown to give full and rapid recovery of muscle strength, thus minimizing the occurrence of residual curarization. Acceleromyography of the adductor pollicis is the gold standard for detecting residual curarization, but it cannot be carried out on conscious patients. Ultrasonography of diaphragm thickness may reveal residual effects of NMBAs in conscious patients. METHODS/DESIGN: This prospective, double-blind, single-center randomized controlled study will enroll patients (of American Society of Anesthesiologists physical status I-II, aged 18 80 years) who will be scheduled to undergo deep neuromuscular block with rocuronium for ear, nose, or throat surgery. The study's primary objective will be to compare the effects of neostigmine and sugammadex on postoperative residual curarization using two different tools: diaphragm ultrasonography and acceleromyography of the adductor pollicis. Patients will be extubated when the train-of-four ratio is > 0.9. Diaphragm ultrasonography will be used to evaluate the thickening fraction, which is the difference between the end expiratory thickness and the end inspiratory thickness, normalized to the end expiratory thickness. Ultrasonography will be performed before the initiation of general anesthesia, before extubation, and 10 and 30 min after discharging patients from the operating room. The secondary objective will be to compare the incidence of postoperative complications due to residual neuromuscular block between patients who receive neostigmine and those who receive sugammadex. DISCUSSION: Postoperative residual curarization is a topic of paramount importance, because its occurrence can cause complications and increase the length of stay in hospital and the related costs. Diaphragm ultrasound assessment may become a bedside integrative tool in the neuromuscular monitoring field to detect concealed residual curarization in surgical patients who have received paralyzing agents.

PMID- 29467023 TI - Protracted immune disorders at one year after ICU discharge in patients with septic shock. AB - BACKGROUND: Sepsis is a leading cause of mortality and critical illness worldwide and is associated with an increased mortality rate in the months following hospital discharge. The occurrence of persistent or new organ dysfunction(s) after septic shock raises questions about the mechanisms involved in the post sepsis status. The present study aimed to explore the immune profiles of patients one year after being discharged from the intensive care unit (ICU) following treatment for abdominal septic shock. METHODS: We conducted a prospective, single center, observational study in the surgical ICU of a university hospital. Eighty six consecutive patients admitted for septic shock of abdominal origin were included in this study. Fifteen different plasma biomarkers were measured at ICU admission, at ICU discharge and at one year after ICU discharge. Three different clusters of biomarkers were distinguished according to their functions, namely: (1) inflammatory response, (2) cell damage and apoptosis, (3) immunosuppression and resolution of inflammation. The primary objective was to characterize variations in the immune status of septic shock patients admitted to ICU up to one year after ICU discharge. The secondary objective was to evaluate the relationship between these biomarker variations and patient outcomes. RESULTS: At the onset of septic shock, we observed a cohesive pro-inflammatory profile and low levels of inflammation resolution markers. At ICU discharge, the immune status demonstrated decreased but persistent inflammation and increased immunosuppression, with elevated programmed cell death protein-1 (PD-1) levels, and a counterbalanced resolution process, with elevated levels of interleukin-10 (IL-10), resolvin D5 (RvD5), and IL-7. One year after hospital discharge, homeostasis was not completely restored with several markers of inflammation remaining elevated. Remarkably, IL-7 was persistently elevated, with levels comparable to those observed after ICU discharge, and PD-1, while lower, remained in the elevated abnormal range. CONCLUSIONS: In this study, protracted immune disturbances were observed one year after ICU discharge. The study results suggested the presence of long-lasting immune illness disorders following a long term septic insult, indicating the need for long-term patient follow up after ICU discharge and questioning the use of immune intervention to restore immune homeostasis after abdominal septic shock. PMID- 29467024 TI - Male synthetic sling versus artificial urinary sphincter trial for men with urodynamic stress incontinence after prostate surgery (MASTER): study protocol for a randomised controlled trial. AB - BACKGROUND: Stress urinary incontinence (SUI) is a frequent adverse effect for men undergoing prostate surgery. A large proportion (around 8% after radical prostatectomy and 2% after transurethral resection of prostate (TURP)) are left with severe disabling incontinence which adversely effects their quality of life and many are reliant on containment measures such as pads (27% and 6% respectively). Surgery is currently the only option for active management of the problem. The overwhelming majority of surgeries for persistent bothersome SUI involve artificial urinary sphincter (AUS) insertion. However, this is expensive, and necessitates manipulation of a pump to enable voiding. More recently, an alternative to AUS has been developed - a synthetic sling for men which elevates the urethra, thus treating SUI. This is thought, by some, to be less invasive, more acceptable and less expensive than AUS but clear evidence for this is lacking. The MASTER trial aims to determine whether the male synthetic sling is non-inferior to implantation of the AUS for men who have SUI after prostate surgery (for cancer or benign disease), judged primarily on clinical effectiveness but also considering relative harms and cost-effectiveness. METHODS/DESIGN: Men with urodynamic stress incontinence (USI) after prostate surgery, for whom surgery is judged appropriate, are the target population. We aim to recruit men from secondary care urological centres in the UK NHS who carry out surgery for post-prostatectomy incontinence. Outcomes will be assessed by participant-completed questionnaires and 3-day urinary bladder diaries at baseline, 6, 12 and 24 months. The 24-h urinary pad test will be used at baseline as an objective assessment of urine loss. Clinical data will be completed at the time of surgery to provide details of the operative procedures, complications and resource use in hospital. At 12 months, men will also have a clinical review to evaluate the results of surgery (including another 24-h pad test) and to identify problems or need for further treatment. DISCUSSION: A robust examination of the comparative effectiveness of the male synthetic sling will provide high-quality evidence to determine whether or not it should be adopted widely in the NHS.

AB - BACKGROUND: No ideal blood pressure (BP) range has been scientifically determined for acute stroke, and no studies on BP management have been carried out for patients with severe stroke. This trial aims to investigate whether individualized lowering of elevated BP would improve the outcome in patients with severe stroke. METHODS/DESIGN: The CHASE trial is a multicenter, randomized, controlled study. A total of 500 adult patients with acute severe stroke will be enrolled in 18 study sites in China and randomized to individualized BP lowering (10-15% reduction from admission level) or guideline-recommended BP lowering. The primary outcome measurement is the proportion of participants with a poor outcome (modified Rankin Scale >= 3) at day 90 of enrollment. Secondary outcomes include disability at hospital discharge and the ability of activities of daily living at day 90 of enrollment. The relationship between intervention and the primary outcome will be analyzed using multivariate logistic regression adjusted for study site, demographics, and baseline characteristics. DISCUSSION: The CHASE trial will be the first study to explore the optimum BP management for acute severe stroke. This trial potentially offers a strong argument for individualized target for lowering elevated BP in patients with severe stroke. TRIAL REGISTRATION: ClinicalTrials.gov, NCT02982655 .

PMID- 29467027 TI - Quality of reporting of outcomes in phase III studies of pulmonary tuberculosis: a systematic review. AB - BACKGROUND: Despite more than 60 years of clinical trials, tuberculosis (TB) still causes a high global burden of mortality and morbidity. Treatment currently requires multiple drugs in combination, taken over a prolonged period. New drugs are needed to shorten treatment duration, prevent resistance and reduce adverse events. However, to improve on current methodology in drug development, a more complete understanding of the existing clinical evidence base is required. METHODS: A systematic review was undertaken to summarise outcomes reported in phase III trials of patients with newly diagnosed pulmonary TB. A systematic search of databases (PubMed, MEDLINE, EMBASE, CENTRAL and LILACs) was conducted on 30 November 2017 to retrieve relevant peer-reviewed articles. Reference lists of included studies were also searched. This systematic review considered all reported outcomes. RESULTS: Of 248 included studies, 229 considered "on treatment" outcomes whilst 148 reported "off-treatment" outcomes. There was wide variation and ambiguity in the definition of reported outcomes, including their relationship to treatment and in the time points evaluated. Additional challenges were observed regarding the analysis approach taken (per protocol versus intention to treat) and the varying durations of "intensive" and "continuation" phases of treatment. Bacteriological outcomes were most frequently reported but radiological and clinical data were often included as an implicit or explicit component of the overall definition of outcome. CONCLUSIONS: Terminology used to define long-term outcomes in phase III trials is inconsistent, reflecting evolving differences in protocols and practices. For successful future cumulative meta-analysis, the findings of this review suggest that greater availability of individual patient data and the development of a core outcome set would be desirable. In the meantime, we propose a simple and logical approach which should facilitate combination of key evidence and inform improvements in the methodology of TB drug development and clinical trials. PMID- 29467028 TI - Diurnal variation of NMDA receptor expression in the rat cerebral cortex is associated with traumatic brain injury damage. AB - OBJECTIVE: Data from our laboratory suggest that recovery from a traumatic brain injury depends on the time of day at which it occurred. In this study, we examined whether traumatic brain injury -induced damage is related to circadian variation in N-methyl-D-aspartate receptor expression in rat cortex. RESULTS: We confirmed that traumatic brain injury recovery depended on the time of day at which the damage occurred. We also found that motor cortex N-methyl-D-aspartate receptor subunit NR1 expression exhibited diurnal variation in both control and traumatic brain injury-subjected rats. However, this rhythm is more pronounced in traumatic brain injury-subjected rats, with minimum expression in those injured during nighttime hours. These findings suggest that traumatic brain injury occurrence times should be considered in future clinical studies and when designing neuroprotective strategies for patients. PMID- 29467029 TI - A newly developed oxime K203 is the most effective reactivator of tabun-inhibited acetylcholinesterase. AB - BACKGROUND: Based on in vitro and in vivo rat experiments, the newly developed acetylcholinesterase (AChE) reactivator, K203, appears to be much more effective in the treatment of tabun poisonings than currently fielded oximes. METHODS: To determine if this reactivating efficacy would extend to humans, studies were conducted in vitro using human brain homogenate as the source of AChE. The efficacy of K203 was compared with commercially available oximes; pralidoxime, obidoxime and asoxime (HI-6). RESULTS: Reactivation studies showed that K203 was the most effective reactivator with a second order kinetic constant (kr) of 2142 min- 1. M- 1, which was 51 times higher than that obtained for obidoxime (kr = 42 min- 1. M- 1). Both pralidoxime and asoxime (HI-6) failed to significantly reactivate tabun-inhibited human AChE. DISCUSSION: According to these results and previous studies, using K203, it appears that oxime K203 is the most effective reactivator of tabun-inhibited cholinesterase in several species including humans and should be considered as a possible medical countermeasure to tabun exposure. PMID- 29467030 TI - Drug discontinuation before contrast procedures and the effect on acute kidney injury and other clinical outcomes: a systematic review protocol. AB - BACKGROUND: Contrast-induced acute kidney injury (CI-AKI) is defined as worsening of renal function after the administration of iodinated contrast material. In patients with cardiovascular disease, kidney disease, and/or diabetes, renin angiotensin system blockers, non-steroidal anti-inflammatory drugs, diuretics, and metformin can increase the risk of CI-AKI when undergoing contrast imaging. Despite CI-AKI being the leading iatrogenic cause of acute kidney injury, there is a lack of sufficient scientific evidence supporting which drugs should be stopped, when they should be stopped, and when they should be resumed. The purpose of this systematic review is to assess (1) the effect of withholding medication before contrast procedures on the risk of CI-AKI and other clinical outcomes and (2) the incidence of adverse events occurring after withholding these drugs prior to contrast procedures. This protocol has been registered with PROSPERO, https://www.crd.york.ac.uk/PROSPERO/display_record.asp?ID=CRD42016033178 . METHODS: An information specialist will assist in searching MEDLINE, Embase, and the Cochrane Library databases to identify randomized controlled trials, observational studies, case reports, and case series. Relevant abstracts from professional society meetings and web-based registries of clinical trials will also be included. Studies included will compare patients aged >= 18 years instructed to continue taking the drugs of interest and those advised to stop taking them before undergoing contrast procedures. If these drugs are not withheld prior to contrast procedures, the studies must compare patients who are administered these drugs and those who are not before undergoing contrast procedures. Two reviewers will independently screen the titles and abstracts of the studies obtained from the search using pre-defined inclusion criteria and will then extract data from the full texts of selected studies. The quality of the studies will be assessed by two independent reviewers using the Cochrane Risk of Bias 2.0 tool for randomized trials and the Newcastle-Ottawa Scale for observational studies. DISCUSSION: This systematic review will provide a synthesis of current evidence on the discontinuation of drugs prior to contrast procedures and its effect on CI-AKI and other clinical outcomes. These findings will provide clinicians with guidelines and serve as a strong research base for future studies in this field. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42016033178. PMID- 29467031 TI - Assessment of communication technology and post-operative telephone surveillance during global urology mission. AB - OBJECTIVE: Compliance with post-operative follow-up in the context of international surgical trips is often poor. The etiology of this problem is multifactorial and includes lack of local physician involvement, transportation costs, and work responsibilities. We aimed to better understand availability of communication technologies within Belize and use this information to improve follow-up after visiting surgical trips to a public hospital in Belize City. Accordingly, a 6-item questionnaire assessing access to communication technologies was completed by all patients undergoing evaluation by a visiting surgical team in 2014. Based on this data, a pilot program for patients undergoing surgery was instituted for subsequent missions (2015-2016) that included a 6-week post-operative telephone interview with a visiting physician located in the United States. RESULTS: Fifty-four (n = 54) patients were assessed via survey with 89% responding that they had a mobile phone. Patients reported less access to home internet (59%), local internet (52%), and email (48%). Of 35 surgical patients undergoing surgery during 2 subsequent surgical trips, 18 (51%) were compliant with telephone interview at 6-week follow-up. Issues were identified in 3 (17%) patients that allowed for physician assistance. The cost per patient interview was $10 USD. PMID- 29467032 TI - Pegylated and liposomal doxorubicin is associated with high mortality and causes limited cardiotoxicity in mice. AB - OBJECTIVE: We wanted to determine the impact of different doses of a pegylated and liposomal formulation of the cardiotoxic drug doxorubicin on cardiac function, fibrosis and survival in mice. The drug causes myocardial damage by producing reactive oxygen species, mitochondrial damage and lipid peroxidation. Thymosin beta 4 is a peptide with cardioprotective, anti-oxidant and anti fibrotic properties and we further investigated whether the peptide could attenuate this drug-induced injury by measuring cardiac function and fibrosis. RESULTS: Mice receiving high doses of doxorubicin died early during follow-up. Lowering the dose improved survival but did not markedly impair cardiac function on echocardiography and caused only limited fibrosis on histology. Thymosin beta 4 had only a mild protective effect on early cardiac function and did not significantly influence myocardial fibrosis. In conclusion, the use of pegylated and liposomal doxorubicin was not appropriate for inducing experimental cardiomyopathy. Thymosin beta 4 therapy was not beneficial in this setting.

AB - BACKGROUND: Brown adipose tissue (BAT) is sympathetically activated and induces thermogenesis during cold exposure, thereby influencing energy expenditure and body fat levels. The very low frequency (VLF) components of pulse rate variability could be a form of thermogenic sympathetic nervous activity, but no clear relationship has yet been reported between VLF activity and BAT density. We therefore aimed to evaluate the association between them. METHODS: We enrolled 20 adults in winter and 20 matched adults in summer. We assessed BAT densities based on total hemoglobin concentrations ([total-Hb]) measured with near-infrared time resolved spectroscopy. We calculated VLF activity from pulse rate variability measurements. RESULTS: BAT density ([total-Hb]; winter 70.5 +/- 17.0 MUM, summer 57.8 +/- 18.3 MUM) and VLF activity (winter 6.7 +/- 0.8, summer 6.1 +/- 0.9) were significantly higher in winter than in summer (P < 0.05). However, there was no significant correlation between VLF activity and BAT density in either season. CONCLUSION: Each parameter exhibited seasonal variation, but we failed to observe any significant correlations. PMID- 29467035 TI - Prevalence and psychometric screening for the detection of major depressive disorder and post-traumatic stress disorder in adults injured in a motor vehicle crash who are engaged in compensation. AB - BACKGROUND: Physical injury and psychological disorder following a motor vehicle crash (MVC) is a public health concern. The objective of this research was to determine rates of major depressive disorder (MDD) and post-traumatic stress disorder (PTSD) in adults with MVC-related injury engaged in compensation, and to determine the capacity (e.g. sensitivity and specificity) of two psychometric scales for estimating the presence of MDD and PTSD. METHODS: Participants included 109 adults with MVC-related injury engaged in compensation during 2015 to 2017, in Sydney, Australia. The mean time from MVC to baseline assessment was 11 weeks. Comprehensive assessment was conducted at baseline, and the Depression Anxiety Stress Scales (DASS-21) and the Impact of Event Scale-Revised (IES-R) were administered to determine probable MDD and PTSD. An online psychiatric interview, based on Diagnostic and Statistical Manual for Mental Disorders (DSM 5), was used to diagnose actual MDD and PTSD, acknowledged as gold standard diagnostic criteria. One-way multivariate analyses of variance established criterion validity of the DASS-21 and IES-R, and sensitivity and specificity analyses were conducted to determine the most sensitive cut-off points for detecting probable MDD and PTSD. RESULTS: Substantial rates of MDD (53.2%) and PTSD (19.3%) were found. The DASS-21 and IES-R were shown to have excellent criterion validity for detecting MDD and PTSD in injured participants. A range of cut-off points were investigated and shown to have acceptable sensitivity and specificity for detecting MDD and PTSD in an injured population engaged in compensation. The preferred cut-off points based on this study are: to detect MDD, a DASS-21 total score of 30 and/or a DASS-21 depression score of 10; to detect PTSD, IES-R scores of 33-40 and/or a DASS-21 anxiety score of 7-8. CONCLUSIONS: Major psychological disorder is prevalent following a MVC. Results suggest the DASS-21 and IES-R are suitable for use in clinical/compensation settings to detect probable MDD and PTSD soon after a MVC in physically injured people engaged in compensation. These results provide positive direction in the public health arena for improving mental health outcomes. TRIAL REGISTRATION: Clinical Trials registration number: ANZCTR - ACTRN12615000326594 (9th April 2015). PMID- 29467037 TI - Strategies for successful trauma registry implementation in low- and middle income countries-protocol for a systematic review. AB - BACKGROUND: The benefits of trauma registries have been well described. The crucial data they provide may guide injury prevention strategies, inform resource allocation, and support advocacy and policy. This has been shown to reduce trauma related mortality in various settings. Trauma remains a leading cause of mortality in low- and middle-income countries (LMICs). However, the implementation of trauma registries in LMICs can be challenging due to lack of funding, specialized personnel, and infrastructure. This study explores strategies for successful trauma registry implementation in LMICs. METHODS: The protocol was registered a priori (CRD42017058586). A peer-reviewed search strategy of multiple databases will be developed with a senior librarian. As per PRISMA guidelines, first screen of references based on abstract and title and subsequent full-text review will be conducted by two independent reviewers. Disagreements that cannot be resolved by discussion between reviewers shall be arbitrated by the principal investigator. Data extraction will be performed using a pre-defined data extraction sheet. Finally, bibliographies of included articles will be hand-searched. Studies of any design will be included if they describe or review development and implementation of a trauma registry in LMICs. No language or period restrictions will be applied. Summary statistics and qualitative meta narrative analyses will be performed. DISCUSSION: The significant burden of trauma in LMIC environments presents unique challenges and limitations. Adapted strategies for deployment and maintenance of sustainable trauma registries are needed. Our methodology will systematically identify recommendations and strategies for successful trauma registry implementation in LMICs and describe threats and barriers to this endeavor. SYSTEMATIC REVIEW REGISTRATION: The protocol was registered on the PROSPERO international prospective register of systematic reviews ( CRD42017058586 ). PMID- 29467036 TI - The living dead? Perception of persons in the unresponsive wakefulness syndrome in Germany compared to the USA. AB - BACKGROUND: The extent to which people ascribe mind to others has been shown to predict the extent to which human rights are conferred. Therefore, in the context of disorders of consciousness (DOC), mind ascription can influence end of life decisions. A previous US-American study indicated that participants ascribed even less mind to patients with unresponsive-wakefulness-syndrome (UWS) than to the dead. Results were explained in terms of implicit dualism and religious beliefs, as highly religious people ascribed least mind to UWS. Here, we addresses mind ascription to UWS patients in Germany. METHODS: We investigate the perception of UWS patients in a large German sample (N = 910) and compare the results to the previous US data, addressing possible cultural differences. We further assess effects of medical expertise, age, gender, socio-economic status and subjective knowledge about UWS in the German sample. RESULTS: Unlike the US sample, German participants did not perceive UWS patients as "more dead than dead", ascribing either equal (on 3 of 5 items) or more (on 2 items) mental abilities to UWS patients than to the dead. Likewise, an effect of implicit dualism was not replicated and German medically trained participants ascribed more capabilities to UWS patients than did a non-medical sample. Within the German sample, age, gender, religiosity and socio-economic status explained about 15% of the variability of mind ascription. Age and religiosity were individually significant predictors, younger and more religious people ascribing more mind. Gender had no effect. CONCLUSION: Results are consistent with cross-cultural differences in the perception of UWS between Germany and the USA, Germans ascribing more mind to UWS patients. The German sample ascribed as much or more but not less mind to a UWS patient than to a deceased, although within group variance was large, calling for further research. Mind ascription is vital, because, in times of declining resources for healthcare systems, and an increasing legalization of euthanasia, public opinion will influence UWS patients' rights and whether 'the right to die' will be the only right conceded to them. PMID- 29467038 TI - Clinical predictors of proteinuric remission following an LN flare - evidence from the UK JSLE cohort study. AB - BACKGROUND: Proteinuria is a well-known risk factor for progression of renal dysfunction in a variety of chronic kidney diseases. In adult-onset Systemic Lupus Erytematosus (SLE) patients with lupus nephritis (LN), proteinuria takes a significant period of time to normalise, with proteinuric remission being associated with improved renal survival and reductions in mortality. The length of time required to attain proteinuric remission has not previously been investigated in Juvenile-onset SLE (JSLE). The aim of this study was to elucidate when proteinuric remission occurs, and whether clinical/demographic factors at LN onset bear influence on the time to proteinuric remission. METHODS: Participants of the UK JSLE Cohort Study and Repository were included if they had active LN (renal biopsy and/or renal British Isles Lupus Assessment Grade (BILAG) score defined active LN) and proteinuria. Univariate Cox proportional hazard regression modelling was used to explore factors associated with time to proteinuric recovery. Covariates with p-value < 0.2 were included in a multivariable Cox regression model, and backward stepwise variable selection applied. RESULT: 64/350 (18%) of UK JSLE Cohort Study patients fulfilled the study inclusion criteria. 25 (39%) achieved proteinuric remission within a median of 17 months (min 2.4, max 78). Within a multivariate Cox proportional hazard regression model, age at time of LN flare (p = 0.007, HR 1.384, CI 1.095-1.750), eGFR (p = 0.035, HR 1.016, CI 1.001-1.030) and haematological involvement (p = 0.016, HR 0.324, CI 0.129-0.812) at the time of LN onset were found to be significantly associated with time to proteinuric recovery. CONCLUSIONS: A significant proportion of children with LN have on-going proteinuria approximately two years after their initial flare. Poor prognostic factors all at time of LN onset include younger age, low eGFR, and concomitant haematological involvement.

Why does this study matter to clinicians? Tailoring knowledge mobilization efforts to end-user priorities is essential to ensure impact and spread of outreach efforts. PMID- 29467039 TI - Influence of lifestyle characteristics and VDR polymorphisms as risk factors for intervertebral disc degeneration: a case-control study. AB - BACKGROUND: Intervertebral disc degeneration (DD) is an important cause of low back pain and its precise aetiology is not fully understood, being attributed to cumulative environmental, biomechanical and genetic effects. The vitamin D plays a key role in regulation of calcium homeostasis and bone mineralization, exerting its biological activities by binding to a high-affinity receptor (VDR). Polymorphisms in VDR gene were previously associated with DD process, however with conflicting results. Here, we aimed to investigate the influence of lifestyle characteristics and VDR TaqI, BsmI, ApaI and FokI polymorphisms as risk factors for DD process. METHODS: Retrospective case-control study involving 231 participants: 119 with confirmed DD and 112 healthy controls. Genotyping of VDR polymorphisms was performed by PCR-RFLP and real-time PCR using TaqMan methodology. All patients answered a questionnaire regarding lifestyle characteristics, such as educational level, pain localization, smoking habits, engagement of physical activity, postural and load weight at work and familial history of disc degeneration. The variables were compared between groups and adjusted by age and gender. RESULTS: The case group was composed by 52% female and 48% male and the mean age was 40.0 years old, while in the control group 79% was female and 21% male and the mean age was 32.0 years old. Although gender distribution and mean age were different between groups, in the control group all participants were less than 45 years old and there was a prevalence of women in both groups. The factors that could be possibly associated to DD in the Brazilian population studied included smoking habits (26% in cases and 9% in controls, p = 0.003), lack of engagement in physical activity (observed in 77% of cases and 62% of controls, p = 0.018), and loading weight during work routine (58% in cases and 24% in controls, p <= 0.001). However, after adjusting by age and gender, only smoking habits remained associated to disc degeneration (p = 0.027). Considering the educational level, 35.2% of cases and 15.6% of controls had only the Elementary School, and 5.5% of DD group and 28.6% of control group had completed College (p = 0.025). In addition, educational level was directly associated to load weight at work (p = 0.012). Regarding VDR polymorphisms, no significant difference in genotype and allele frequencies between groups was observed. The haplotype analysis revealed that the combined wild-type alleles of TaqI, ApaI and FokI polymorphisms-TGT-was observed in a higher frequency in control group (p = 0.039). CONCLUSION: The findings suggested that smoking habits was a risk factor for disc degeneration in the population studied. Single analysis revealed no significant effects of VDR polymorphisms in disc degeneration process, while the combination of wild-type alleles of TaqI, ApaI and FokI polymorphisms, TGT haplotype, decreased the risk of the disease. PMID- 29467041 TI - Interviewer effects in food acquisition surveys. AB - OBJECTIVE: To understand the effects of interviewers on the responses they collect for measures of food security, income and selected survey quality measures (i.e. discrepancy between reported Supplemental Nutrition Assistance Program (SNAP) status and administrative data, length of time between initial and final interview, and missing income data) in the US Department of Agriculture's National Household Food Acquisition and Purchase Survey (FoodAPS). DESIGN: Using data from FoodAPS, multilevel models with random interviewer effects were fitted to estimate the variance in each outcome measure arising from effects of the interviewers. Covariates describing each household's socio-economic status, demographics and experience in taking the survey, and interviewer-level experience were included as fixed effects. The variance components in the outcomes due to interviewers were estimated. Outlier interviewers were profiled. SETTING: Non-institutionalized households in the continental USA (April 2012 January 2013). SUBJECTS: Individuals (n 14 317) in 4826 households who responded to FoodAPS. RESULTS: There was a substantial amount of variability in the distributions of the outcomes examined (i.e. time between initial and final interview, reported values for food security, individual income, missing income) among the FoodAPS interviewers, even after accounting for the fixed effects of the household- and interviewer-level covariates and removing extreme outlier interviewers. CONCLUSIONS: Interviewers may introduce error in food acquisition survey data when they are asked to interact with the respondents. Managers of future surveys with similarly complex data collection procedures could consider using multilevel models to adaptively identify and retrain interviewers who have extreme effects on data collection outcomes. PMID- 29467042 TI - Effect of selected plant species within biodiverse pasture on in vitro fatty acid biohydrogenation and tissue fatty acid composition of lamb. AB - The effect of botanical diversity on supply of polyunsaturated fatty acids (PUFA) to ruminants in vitro, and the fatty acid (FA) composition of muscle in lambs was investigated. Six plant species, commonly grown as part of UK herbal ley mixtures (Trifolium pratense, Lotus corniculatus, Achillea millefolium, Centaurea nigra, Plantago lanceolata and Prunella vulgaris), were assessed for FA profile, and in vitro biohydrogenation of constituent PUFA, to estimate intestinal supply of PUFA available for absorption by ruminants. Modelling the in vitro data suggested that L. corniculatus and P. vulgaris had the greatest potential to increase 18:3n-3 supply to ruminants, having the highest amounts escaping in vitro biohydrogenation. Biodiverse pastures were established using the six selected species, under-sown in a perennial ryegrass-based sward. Lambs were grazed (~50 days) on biodiverse or control pastures and the effects on the FA composition of musculus longissimus thoracis (lean and subcutaneous fat) and musculus semimembranosus (lean) were determined. Biodiverse pasture increased 18:2n-6 and 18:3n-3 contents of m. semimembranosus (+14.8 and +7.2 mg/100 g tissue, respectively) and the subcutaneous fat of m. longissimus thoracis (+158 and +166 mg/100 g tissue, respectively) relative to feeding a perennial ryegrass pasture. However, there was no effect on total concentrations of saturated FA in the tissues studied. It was concluded that enhancing biodiversity had a positive impact on muscle FA profile reflected by increased levels of total PUFA. PMID- 29467043 TI - Three-dimensional spheroid culture of adipose stromal vascular cells for studying adipogenesis in beef cattle. AB - Protocols designed for the adipogenic differentiation of human and mouse cells are commonly used for inducing the adipogenesis of bovine stromal vascular cells. However, likely due to metabolic differences between ruminant and non-ruminant animals, these methods result in only few cells undergoing complete adipogenesis with minimal lipid droplet accumulation. Here, we discuss the development of an adipogenic differentiation protocol for bovine primary cells through a three dimensional spheroid culture. Stromal vascular cells derived from bovine intramuscular fat were isolated and stored in liquid nitrogen before culturing. Cells were cultured in hanging drops for 3 days to allow for the formation of spherical structures. The spheroids were then transferred to cell culture plates with endothelial basal medium-2 for 3 days and in Dulbecco's Modified Eagle's Medium (DMEM) supplemented with a standard adipogenic cocktail for 3 additional days, which were then allowed to fully differentiate for 3 days in DMEM supplemented with insulin. Compared with conventional two-dimensional culture, cells in a three-dimensional spheroid culture system had higher adipogenic gene expression and consequently contained more adipocytes with larger lipid droplets. In addition, endothelial induction of spheroids prior to adipogenic differentiation is essential for efficient induction of adipogenesis of bovine stromal vascular cells, mimicking in vivo adipose development. In summary, the newly developed three-dimensional spheroid culture method is an efficient way to induce adipogenic differentiation and study adipose development of cells derived from ruminant animals, which also can be used for studying the role of angiogenesis in adipose development. PMID- 29467044 TI - Pedigree analysis and inbreeding effects over morphological traits in Campolina horse population. AB - Genetic improvement, without control of inbreeding, can go to loss of genetic variability, reducing the potential for genetic gains in the domestic populations. The aim of this study was to analyze the population structure and the inbreeding depression in Campolina horses. Phenotype information from 43 465 individuals was analyzed, data provided by the Campolina Breeders Association. A pedigree file containing 107 951 horses was used to connected the phenotyped individuals. The inbreeding coefficient was performed by use of the diagonal of the relationship matrix and the genealogical parameters were computed using proper softwares. The effective population size was estimated based on the rate of inbreeding and census information, and the stratification of the population was verified by the average relationship coefficient between animals born in different regions of Brazil. The effects of inbreeding on morphological traits were made by the use of inbreeding coefficient as a covariate in the model of random regression. The inbreeding coefficient increased from 1990 on, impacting effective population size and, consequently, shrinking genetic variability. The paternal inbreeding was greater than maternal, which may be attributed to the preference for inbred animals in reproduction. The average genetic relationship coefficient of animals born in different states was lower than individuals born within the same state. The increase in the inbreeding coefficient was negatively associated with all studied traits, showing the importance to avoid genetic losses in the long term. Although results do not indicate a severe narrowing of the population until the present date, the average relationship coefficient shows signs of increase, which could cause a drastic reduction in genetic variability if inbred mating is not successfully controlled in the Campolina horse population. PMID- 29467045 TI - SYSTEMATIC REVIEW WITH NETWORK META-ANALYSIS OF RANDOMIZED CONTROLLED TRIALS OF ROTATOR CUFF TEAR TREATMENT. AB - OBJECTIVES: Rotator cuff tear is the leading cause of the decline in quality of life for older adults, but comparative evidence on treatment effectiveness is lacking. This study systematically reviewed the effects of various rotator cuff tear treatments through a Bayesian meta-analysis of the related randomized clinical trials (RCTs). METHODS: We searched nine electronic databases for RCTs evaluating rotator cuff tear treatments from their inception through June 2017. A systematic review was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and the National Institute for Health and Care Excellence-Decision Support Unit guidelines (Supplementary Table 1). Outcomes included functional improvement, pain one year after surgical treatment, and tendon structural integrity. The Bayesian network meta-analysis was applied for functional improvement and pain, based on an assumption of consistency and similarity. Tendon integrity was reported descriptively. RESULTS: Fifteen RCTs were selected. Patients undergoing physiotherapy after open surgery showed statistically significant functional improvements compared with those undergoing physiotherapy only (mean differences, 9.1 [credible interval, 0.9 17.4]). Open surgery with physiotherapy was associated with a decrease in pain 1 year after treatment compared with when physiotherapy was combined with arthroscopic rotator cuff surgery, mini open surgery, platelet-rich plasma therapy, or physiotherapy alone (absolute value of mean difference 1.2 to 1.4). The tendon integrity results were inconsistent. CONCLUSIONS: Some surgical treatments were associated with significant improvement in function and pain, but evidence regarding their comparative effectiveness is still lacking. A well designed RCT discussing functional and structural treatment outcomes is needed in future. PMID- 29467046 TI - The interaction between monoamine oxidase A (MAOA) and childhood maltreatment as a predictor of personality pathology in females: Emotional reactivity as a potential mediating mechanism. AB - Research consistently demonstrates that common polymorphic variation in monoamine oxidase A (MAOA) moderates the influence of childhood maltreatment on later antisocial behavior, with growing evidence that the "risk" allele (high vs. low activity) differs for females. However, little is known about how this Gene * Environment interaction functions to increase risk, or if this risk pathway is specific to antisocial behavior. Using a prospectively assessed, longitudinal sample of females (n = 2,004), we examined whether changes in emotional reactivity (ER) during adolescence mediated associations between this Gene * Environment and antisocial personality disorder in early adulthood. In addition, we assessed whether this putative risk pathway also conferred risk for borderline personality disorder, a related disorder characterized by high ER. While direct associations between early maltreatment and later personality pathology did not vary by genotype, there was a significant difference in the indirect path via ER during adolescence. Consistent with hypotheses, females with high-activity MAOA genotype who experienced early maltreatment had greater increases in ER during adolescence, and higher levels of ER predicted both antisocial personality disorder and borderline personality disorder symptom severity. Taken together, findings suggest that the interaction between MAOA and early maltreatment places women at risk for a broader range of personality pathology via effects on ER. PMID- 29467047 TI - Myocardial stress perfusion magnetic resonance in children with hypertrophic cardiomyopathy. AB - BACKGROUND: Microvascular dysfunction in hypertrophic cardiomyopathy has been associated with poor clinical outcome. Several studies have demonstrated a reduced perfusion reserve proportional to the magnitude of the hypertrophy. We investigated the utility of stress perfusion cardiac MRI to detect microvascular dysfunction in children with hypertrophic cardiomyopathy. METHODS: From January 2016 to January 2017, 13 patients, with a mean age of 15.3 years, with hypertrophic cardiomyopathy underwent regadenoson stress perfusion cardiac MRI (1.5-T Siemens Aera). A single-shot, T1-weighted saturation recovery gradient echo was used for first-pass perfusion in a multiple-slices group, including three short-axis slices and one four-chamber slice. Coronary vasodilatory stress was achieved using bolus injection of regadenoson (lexiscan 0.4 mg/5 ml) and dynamic perfusion during rest and stress performed by administering 0.05 mmol/kg of gadolinium contrast agent (gadoteridol) injected at a rate of 3.5 ml/s, followed by assessment of viability using two-dimensional phase-sensitive inversion recovery of the entire myocardium. RESULTS: All patients completed protocols with no interruptions. In all, seven patients developed perfusion defects after the administration of regadenoson. Asymmetric septal hypertrophy was the most common pattern of hypertrophic cardiomyopathy (n=4) in those with abnormal perfusion. A total of four patients with perfusion defects had a maximum wall thickness <30 mm. The finding of perfusion defects in areas without late gadolinium enhancement in some of our patients indicates that gadolinium enhancement by itself could underestimate the true extension of microvascular disease. Out of seven patients, five patients with positive stress cardiac MRI have undergone implantable cardioverter defibrillator placement based on current guidelines. CONCLUSIONS: Regadenoson stress cardiac MRI is feasible and clinically valuable in paediatric patients. It is particularly effective in unmasking abnormal myocardial perfusion in the presence of microvascular dysfunction in children with hypertrophic cardiomyopathy. PMID- 29467048 TI - Pregnancy-associated spontaneous coronary artery dissection (PASCAD): An etiology for chest pain in the young peripartum patient. AB - Cardiac emergencies in pregnancy and the postpartum period are rare but often life-threatening. An emergency physician's differential diagnosis for chest pain in the peripartum patient often includes serious etiologies such as pulmonary embolism or myocardial infarction (MI). A lesser-known but important consideration on the differential for MI is that of a spontaneous coronary artery dissection (SCAD). SCAD is defined as an intramural hematoma within the coronary artery that compresses the true lumen. Expansion by increased pressures may lead to subsequent myocardial ischemia and infarction. This condition is the most common cause of pregnancy-associated MI and is reported as the cause of MI in 24% to 35% of all women younger than 50 years. This condition is predominately seen in young healthy females with no traditional risk factors for coronary artery or cardiac disease, and typically in the postpartum period. SCAD in the peripartum period is defined as pregnancy-associated spontaneous coronary artery dissection (PASCAD). Abnormal ECG changes, elevated troponins, and regional wall motional abnormalities on echocardiography are all diagnostic findings of SCAD, which can be ultimately confirmed with coronary angiography. Failure to immediately address this condition can lead to acute heart failure, cardiogenic shock, and death. Thrombolytic treatment may be harmful and is not recommended, and percutaneous coronary intervention can result in the iatrogenic propagation of further coronary dissection. As a result, the management for suspected SCAD involves emphasis on urgent transfer and urgent coronary artery angiography to determine appropriate treatment modalities.

AB - The aim of this study was to compare the effects of various activating factors on feline oocytes. The study included activation within the ovary (natural), activation during in vitro maturation (spontaneous activation), chemical activation (ionomycin + 6-DMAP), activation by spermatozoa and injection (ICSI) and mechanical activation (sham ICSI). According to our results, parthenogenetic embryos could emerge at every step of in vitro embryo production (IVP) procedures. After oocyte collection, 6% of parthenogenetic embryos were observed, mainly at the 2-4-blastomere stages. After 24 h of in vitro maturation, parthenogenetic activation was observed in 7% of oocytes. Using ionomycin and 6 DMAP to artificially activate oocytes, 53% of cleaved embryos were obtained. The results after ICSI (54% cleaved embryos) were not significantly different from the results in Group III using chemical activation (53% cleaved embryos). But only after ICSI were blastocysts obtained (5/73.7%) as a result of in vitro culture. Moreover, embryos after ICSI were of the best morphological quality with minor levels of fragmentation evident in the embryos. After sham mechanical activation, 'sham ICSI', 8% of cleaved embryos were noted. Therefore, it is advised to maintain a negative control in parallel with each step of IVP techniques, to avoid misleading results. Chemical methods for artificial activation of feline oocytes are the most promising for application to the cloning and production of parthenogenetic embryos for experimental studies. PMID- 29467050 TI - Does the diurnal pattern of enteric methane emissions from dairy cows change over time? AB - Diet manipulation and genetic selection are two important mitigation strategies for reducing enteric methane (CH4) emissions from ruminant livestock. The aim of this study was to assess whether the diurnal pattern of CH4 emissions from individual dairy cows changes over time when cows are fed on diets varying in forage composition. Emissions of CH4 from 36 cows were measured during milking in an automatic (robotic) milking station in three consecutive feeding periods, for a total of 84 days. In Periods 1 and 2, the 36 cows were fed a high-forage partial mixed ration (PMR) containing 75% forage, with either a high grass silage or high maize silage content. In Period 3, cows were fed a commercial PMR containing 69% forage. Cows were offered PMR ad libitum plus concentrates during milking and CH4 emitted by individual cows was sampled during 8662 milkings. A linear mixed model was used to assess differences among cows, feeding periods and time of day. Considerable variation was observed among cows in daily mean and diurnal patterns of CH4 emissions. On average, cows produced less CH4 when fed on the commercial PMR in feeding Period 3 than when the same cows were fed on high forage diets in feeding Periods 1 and 2. The average diurnal pattern for CH4 emissions did not significantly change between feeding periods and as lactation progressed. Emissions of CH4 were positively associated with dry matter (DM) intake and forage DM intake. It is concluded that if the management of feed allocation remains constant then the diurnal pattern of CH4 emissions from dairy cows will not necessarily alter over time. A change in diet composition may bring about an increase or decrease in absolute emissions over a 24-h period without significantly changing the diurnal pattern unless management of feed allocation changes. These findings are important for CH4 monitoring techniques that involve taking measurements over short periods within a day rather than complete 24-h observations. PMID- 29467051 TI - Primary Care Medical Practices: Are Community Health Care Providers Ready for Disasters? AB - OBJECTIVE: This study seeks to determine the capacity of community primary care practices to meet the needs of patients during public health emergencies and to identify the barriers and resources necessary to participate in a coordinated response with public safety agencies. METHODS: The self-administered web-based survey was distributed in January 2014 via e-mail to primary care providers in Pennsylvania using the listservs of several professional societies. RESULTS: A total of 179 primary care providers participated in the survey. In total, 38% had practice continuity of operations plan in place and 26% reported that they had a plan for patient surge in the outpatient setting. Thirty percent reported that they were registered on the state Health Alert Network and 41% said they were able to communicate with patients during disasters. Only 8% of providers reported that they believed that their patients with special health care needs were prepared for a disaster, although over two-thirds of responding practices felt they could assist these patients with disaster preparedness. Providers indicated that more information regarding government agency plans and community resources, patient education materials, and more time to devote to counseling during patient encounters would improve their ability to prepare their patients with special health care needs for disasters. Providers also reported that they would benefit from partnerships to help the practice during emergencies and communications technology to reach large numbers of patients quickly. CONCLUSIONS: Community based primary care practices can be useful partners during public health emergencies. Efforts to promote continuity of operations planning, improved coordination with government and community partners, as well as preparedness for patients with special health care needs, would augment their capabilities and contribute to community resilience.

AB - BACKGROUND: Considering existing knowledge on the relationship between certain environmental factors and incidence rates of psychosis, we carried out a systematic review to provide a broad and updated picture of the incidences of different psychotic disorder subgroups worldwide and how some environmental factors influence these rates. METHODS: Studies with original data related to the incidence of psychosis (published between 2000 and 2015) were identified via searching electronic databases (CINAHL, MEDLINE, PSYCINFO, PUBMED, and SCOPUS). Data on the following risk factors were extracted: gender, urbanicity, immigration and socio-economic level. Descriptive appraisals of variation in incidence rates (IR) and incidence rate ratios (IRR), with a 95% confidence interval were calculated. In addition, a meta-analysis was performed to calculate IR pooled by diagnosis group and IRR pooled by diagnosis and gender, urbanity, immigration and socio-economic level, using a random effects model. RESULTS: We identified 33 reports to analyse. Overall IR per 100 000 persons for non affective psychoses (IR pooled = 22.53 (16.51-28.54)) were higher than affective psychoses (IR pooled = 7.12 (5.03-9.22)). There was an increase in rates of psychosis in men v. women (IRR pooled = 1.54 (1.37-1.72)), in urban v. rural areas (IRR pooled = 1.64 (1.38-1.95)), in immigrants v. natives (IRR pooled = 3.09 (2.74-3.49)), and in lower socio-economic level areas (IRR pooled = 1.78 (1.43-2.22)). CONCLUSIONS: IR among different psychotic disorders was found to vary depending on gender, urbanicity, and immigration (as most of the previous literature focuses on non-affective psychosis or schizophrenia). PMID- 29467053 TI - Randomized control trials demonstrate that nutrition-sensitive social protection interventions increase the use of multiple-micronutrient powders and iron supplements in rural pre-school Bangladeshi children. AB - OBJECTIVE: To examine the impact of a nutrition-sensitive social protection intervention on mothers' knowledge of Fe deficiency, awareness of multiple micronutrient powders (MMP) and the consumption of MMP and other Fe supplements by their children aged 6-59 months. DESIGN: Two randomized controlled trials with treatment arms including cash transfers, food transfers, cash and food transfers, cash and nutrition behaviour change communication (BCC), and food and nutrition BCC were implemented over two years. Both included a control group that received no transfer or BCC. Transfer recipients were mothers living in poor households with at least one child aged less than 2 years at baseline. Probit models were used to analyse endline data. SETTING: Rural areas in north-west and south Bangladesh. SUBJECTS: Mothers (n 4840) and children 6-59 months (n 4840). RESULTS: A transfer accompanied by nutrition BCC increased the share of mothers with knowledge of Fe deficiency (11.9 and 9.2 percentage points for North and South, respectively, P<=0.01), maternal awareness of MMP (29.0 and 22.2 percentage points, P<=0.01), the likelihood that their children 6-59 months had ever consumed MMP (32 and 11.9 percentage points, P<=0.01), consumed MMP in the preceding week (16.9 and 3.9 percentage points, P<=0.01) and consumed either MMP or an Fe supplement in the preceding week (22.3 and 7.1 percentage points, P<=0.01). Improvements were statistically significant relative to groups that received a transfer only. CONCLUSIONS: Nutrition-sensitive social protection (transfers with BCC added) may be a promising way to advance progress on micronutrient deficiencies.

PMID- 29467055 TI - Molecular serogrouping of Escherichia coli. AB - O-antigens present on the surface of Escherichia coli provide antigenic specificity for the strain and are the main components for O-serogroup designation. Serotyping using O-group-specific antisera for the identification of E. coli O-serogroups has been traditionally the gold-standard for distinguishing E. coli strains. Knowledge of the O-group is important for determining pathogenic lineage, classifying E. coli for epidemiological studies, for determining virulence, and for tracing outbreaks of diseases and sources of infection. However, serotyping has limitations, as the antisera generated against each specific O-group may cross-react, many strains are non-typeable, and others can autoagglutinate or be rough (lacking an O-antigen). Currently, the nucleotide sequences are available for most of the 187 designated E. coli O-groups. Public health and other laboratories are considering whole genome sequencing to develop genotypic methods to determine O-groups. These procedures require instrumentation and analysis that may not be accessible and may be cost-prohibitive at this time. In this review, we have identified unique gene sequences within the O-antigen gene clusters and have targeted these genes for identification of O-groups using the polymerase chain reaction. This information can be used to distinguish O groups by developing other platforms for E. coli diagnostics in the future. PMID- 29467056 TI - Review: Integrating a semen quality control program and sire fertility at a large artificial insemination organization. AB - The technology available to assess sperm population characteristics has advanced greatly in recent years. Large artificial insemination (AI) organizations that sell bovine semen utilize many of these technologies not only for novel research purposes, but also to make decisions regarding whether to sell or discard the product. Within an AI organization, the acquisition, interpretation and utilization of semen quality data is often performed by a quality control department. In general, quality control decisions regarding semen sales are often founded on the linkages established between semen quality and field fertility. Although no one individual sperm bioassay has been successful in predicting sire fertility, many correlations to various in vivo fertility measures have been reported. The most powerful techniques currently available to evaluate semen are high-throughput and include computer-assisted sperm analysis and various flow cytometric analyses that quantify attributes of fluorescently stained cells. However, all techniques measuring biological parameters are subject to the principles of precision, accuracy and repeatability. Understanding the limitations of repeatability in laboratory analyses is important in a quality control and quality assurance program. Hence, AI organizations that acquire sizeable data sets pertaining to sperm quality and sire fertility are well positioned to examine and comment on data collection and interpretation. This is especially true for sire fertility, where the population of AI sires has been highly selected for fertility. In the December 2017 sire conception rate report by the Council on Dairy Cattle Breeding, 93% of all Holstein sires (n=2062) possessed fertility deviations within 3% of the breed average. Regardless of the reporting system, estimates of sire fertility should be based on an appropriate number of services per sire. Many users impose unrealistic expectations of the predictive value of these assessments due to a lack of understanding for the inherent lack of precision in binomial data gathered from field sources. Basic statistical principles warn us of the importance of experimental design, balanced treatments, sampling bias, appropriate models and appropriate interpretation of results with consideration for sample size and statistical power. Overall, this review seeks to describe and connect the use of sperm in vitro bioassays, the reporting of AI sire fertility, and the management decisions surrounding the implementation of a semen quality control program. PMID- 29467057 TI - Prevalence and predictors of involuntary psychiatric hospital admissions in Ontario, Canada: a population-based linked administrative database study. AB - BACKGROUND: Involuntary admissions to psychiatric hospitals are common; however, research examining the trends in prevalence over time and predictors is limited. Aims To examine trends in prevalence and risk factors for involuntary admissions in Ontario, Canada. METHOD: We conducted an analysis of all mental health bed admissions from 2009 to 2013 and assessed the association between patient sociodemographics, service utilisation, pathway to care and severity characteristics for involuntary admissions using a modified Poisson regression. RESULTS: We found a high and increasing prevalence of involuntary admissions (70.7% in 2009, 77.1% in 2013, 74.1% overall). Individuals with police contact in the prior week (risk ratio (RR) = 1.20) and immigrants both experienced greater likelihood of being involuntarily admitted, regardless of control for other characteristics (RR = 1.07) (both P < 0.0001). CONCLUSIONS: We identified numerous modifiable and non-modifiable risk factors for involuntary admissions. The prevalence of involuntary admissions was high, linearly increasing over time.

PMID- 29467058 TI - Trends in female authorship in research papers on eating disorders: 20-year bibliometric study. AB - BACKGROUND: There is a clear gender gap in scientific authorship. Although the proportions of female authors in medicine and psychiatry have increased over the past decades, women are still underrepresented. Aims To analyse authorship gender trends in eating disorder research. METHOD: First and last author gender in research articles on eating disorders during the period 1997-2016 were assessed in eating disorder specialty journals, high-impact psychiatry journals and high impact clinical psychology journals. RESULTS: The total number of papers on eating disorders increased substantially over the observation period, although a decrease was observed in high-impact psychiatry journals. Female authorship increased in both specialty journals and high-impact psychiatry journals. Authors were significantly less likely to be female in high-impact psychiatry and clinical psychology journals than in speciality journals. CONCLUSIONS: Eating disorder research has been increasingly allocated to specialty journals over the past 20 years. A consistent gender gap between specialty and high-impact journals exists.

PMID- 29467059 TI - Creation of a Collaborative Disaster Preparedness Video for Daycare Providers: Use of the Delphi Model for the Creation of a Comprehensive Disaster Preparedness Video for Daycare Providers. AB - OBJECTIVE: Eight million American children under the age of 5 attend daycare and more than another 50 million American children are in school or daycare settings. Emergency planning requirements for daycare licensing vary by state. Expert opinions were used to create a disaster preparedness video designed for daycare providers to cover a broad spectrum of scenarios. METHODS: Various stakeholders (17) devised the outline for an educational pre-disaster video for child daycare providers using the Delphi technique. Fleiss kappa values were obtained for consensus data. A 20-minute video was created, addressing the physical, psychological, and legal needs of children during and after a disaster. Viewers completed an anonymous survey to evaluate topic comprehension. RESULTS: A consensus was attempted on all topics, ranging from elements for inclusion to presentation format. The Fleiss kappa value of 0.07 was obtained. Fifty-seven of the total 168 video viewers completed the 10-question survey, with comprehension scores ranging from 72% to 100%. CONCLUSION: Evaluation of caregivers that viewed our video supports understanding of video contents. Ultimately, the technique used to create and disseminate the resources may serve as a template for others providing pre-disaster planning education.

AB - A growing global concern of antibiotic use in poultry diets due to its potential adverse effects on birds and human health, food safety and the environment has led to a complete ban or restricted use in some countries, and, at the same time, expanding options for the use of alternative feed additives. Multiple, rather than a single additive may replace antibiotic growth promoters (AGPs) in poultry. Blending of feeding additives and hygienic farm management, vaccination and biosecurity may help achieve good intestinal health, stabilise enteric ecosystems and result in sustainable and cost effective production performance of birds. Moreover, controlling unsolicited ingredients at the production level must have the support of different markets responsible for the supply of safe and quality poultry products for consumers. This requires the further increase and diversification of value added poultry products and the expansion of their markets through strategic planning and gradual limitation of live bird markets. More research is warranted in order to explore suitable, reliable and cost effective alternatives to AGPs for commercial use, and strategic poultry value chain development.

AB - Occasionally, residents actively or passively refuse to take medications. Residents may refuse medication for a number of reasons, including religious beliefs, dietary restrictions, misunderstandings, cognitive impairment, desire to self-harm, or simple inconvenience. This action creates a unique situation for pharmacists and long-term facility staff, especially if patients have dementia. Residents have the legal right to refuse medications, and long-term care facilities need to employ a process to resolve disagreement between the health care team that recommends the medication and the resident who refuses it. In some cases, simple interventions like selecting a different medication or scheduling medications in a different time can address and resolve the resident's objection. If the medical team and the resident cannot resolve their disagreement, often an ethics consultation is helpful. Documenting the resident's refusal to take any or all medications, the health care team's actions and any other outcomes are important. Residents' beliefs may change over time, and the health care team needs to be prepared to revisit the issue as necessary. PMID- 29467066 TI - Balanitis: A Unique Presentation of Diabetes in an Elderly Male. AB - While diabetes is a common medical condition, the initial presentation of patients with diabetes may vary. In some cases, different types of infections or inflammatory conditions may prompt a patient to seek medical attention. Males may present to their primary care provider with a bothersome inflammation of the penis that may be the first recognition of previously undiagnosed diabetes. Balanitis is an inflammation of the glans of the penis that may prompt a patient to seek medical care. While there are several different causes of balanitis, underlying medical conditions such as uncontrolled diabetes have been associated with balanitis. The genital irritation prompts patients to seek medical evaluation, and at that point diabetes is diagnosed. It is important for pharmacists to recognize that balanitis is a potential though uncommon type of diabetes presentation. It is also important for pharmacists to review other aspects of diabetes care once a patient is diagnosed with diabetes. PMID- 29467067 TI - A Brief Review of Caprylidene (Axona) and Coconut Oil as Alternative Fuels in the Fight Against Alzheimer's Disease. AB - Type 3 diabetes mellitus has been coined to describe an alternative pathologic pathway of Alzheimer's disease (AD). The insulin resistance and impaired insulin signaling seen on positron-emission tomography scans in the brain of those affected by AD support this disease hypothesis. Two products-the medical food caprylidene (Axona) and coconut oil-seek to target the underlying pathology of type 3 diabetes mellitus by providing an alternative fuel source in the brain. Rather than improving glucose utilization, these two products seek to supply ketone bodies in sufficient quantities to pass through the blood-brain barrier and provide an alternative energy source to glucose. This review will provide an overview of the research behind these two modalities, as well as information necessary to ensure the safe use of these supplements. PMID- 29467068 TI - Comparison of Two Versions of the Beers Criteria and Adverse Outcomes in Older Hospitalized Patients. AB - OBJECTIVE: To compare the performance of the 2003 and 2012 Beers criteria (BC) to predict negative clinical outcomes associated with potentially inappropriate medications in hospitalized older adults. DESIGN: Retrospective cohort study. SETTING: Acute Care of Elders (ACE) unit in a community-based teaching hospital. PARTICIPANTS: All patients admitted to an ACE unit who were older than 65 years of age and prescribed at least one medication upon hospital admission. MAIN OUTCOME MEASURE(S): The primary outcome was hospital length of stay (LOS). Secondary outcomes included likelihood of experiencing adverse drug events (ADEs) and in-hospital mortality. RESULTS: A total of 340 patients were included in this study. Inpatients prescribed a BC drug at any time had a longer hospital LOS than those not prescribed a BC drug (2003 BC: adjusted geometric mean, 5.93 vs. 5.50 days, P = 0.003; 2012 BC: adjusted geometric mean, 5.87 vs. 4.21 days, P < 0.001). Patients prescribed a 2003 BC drug had an increased risk of experiencing an ADE compared with those not prescribed a BC drug (odds ratio [OR] = 1.86, 95% confidence interval [CI] 1.11-3.11); however, this outcome was not statistically significant after adjusting for confounders (OR = 1.51, 95% CI 0.870-2.63). There was no statistically significant difference in ADEs when using the 2012 BC (adjusted OR = 1.27, 95% CI 0.689-2.33). There was no difference in hospital mortality regardless of the BC version used. CONCLUSION: Prescription of BC drugs in an acute care setting is associated with an increased hospital LOS; however, there is no difference in the risk of ADEs or in-hospital mortality. PMID- 29467069 TI - Determination of Anticholinergic Medication Use in Patients Prescribed Medications for the Treatment of Dementia. AB - OBJECTIVE: The primary endpoint of the study is to determine the variations in the use of medications to treat dementia in patients concomitantly or not prescribed anticholinergics. DESIGN: The study is a case series of patients at a single community pharmacy over one year based on prescription claims data. SETTING: The setting is an independent community pharmacy in the South. MAIN OUTCOME MEASURE(S): The main outcome is the variations associated in treatment plans for patients either receiving anticholinergics or not receiving medications with anticholinergic properties. RESULTS: The community pharmacy had 33 patients on medications to treat dementia, and 17 patients (51.5%) were prescribed anticholinergic medications. Only patients on anticholinergic medications were prescribed memantine immediate-release. Fifteen patients (93%) not prescribed anticholinergic medications were on a single medication to treat dementia, whereas 9 patients (52%) prescribed anticholinergic medications were on a single medication to treat dementia. CONCLUSION: Further research should be conducted in this area to better ascertain the impact anticholinergic medications have on patients. This study noted differences from previous data regarding the prevalence of concomitant prescribing of medications for the treatment of dementia and anticholinergics.

PMID- 29467071 TI - Relative contribution of overweight and obesity to rising public hospital in patient expenditure in South Australia. AB - Objective Arguments to fund obesity prevention have often focused on the growing hospital costs of associated diseases. However, the relative contribution of overweight and obesity to public hospital expenditure growth is not well understood. This paper examines the effect of overweight and obesity on acute public hospital in-patient expenditure in South Australia over time compared with other expenditure drivers.Methods Annual inflation-adjusted acute public admitted expenditure attributable to a high body mass index was estimated for 2007-08 and 2011-12 and compared with other expenditure drivers.Results Expenditure attributable to overweight and obesity increased by A$45million, from 4.7% to 5.4% of total acute public in-patient expenditure. This increase accounted for 7.8% of the A$583million total expenditure growth, whereas the largest component of total growth (62.4%) was a real increase in the average cost per separation.Conclusions The relatively minor contribution of overweight and obesity to expenditure growth over the time period examined invites reflection on arguments to boost preventive spending that centre upon reducing hospital costs. These arguments may inadvertently detract attention from the considerable health and social burdens of overweight and obesity and from unrelated sources of expenditure growth that reduce opportunities for state governments to fund obesity prevention programs despite their comparative benefits to population health.What is known about the topic? Stand-alone estimates suggest that overweight and obesity are placing a considerable financial burden on the Australian public healthcare system.What does this paper add? Our findings challenge common perceptions about the relative importance of overweight and obesity in the context of rising public in-patient expenditure in Australia.What are the implications for practitioners? Consistent serial estimates of overweight and obesity-attributable expenditure enable its tracking and comparison with other potentially controllable expenditure drivers that may also warrant attention. Explicit consideration of population health trade-offs in expenditure related decisions, including in enterprise bargaining, would enhance transparency in priority setting. PMID- 29467072 TI - Social Gradients in Myocardial Infarction and Stroke Diagnoses in Emergency Medicine. AB - BACKGROUND: Persons of lower socio-economic status are at higher risk of disease, especially with respect to severe and chronic illnesses. To date, there have not been any studies with large case numbers regarding acute medical emergencies in this population. METHODS: In a retrospective study, data were obtained on all cases treated by emergency physicians in Bochum, Germany, in 2014/2015, including the diagnoses that were made by the emergency physicians. There were a total of 16 767 cases. The local unemployment rate was taken as an indicator of the socioeconomic situation of a neighborhood; it was defined as the percentage of registered unemployed persons among persons aged 15 to 64 with their domicile in the neighborhood. 12 168 cases were grouped by emergency medical diagnosis and analyzed with respect to the three most heavily represented diagnostic categories (cardiovascular, neurological, and pulmonary emergencies), which accounted for nearly two-thirds of all diagnoses. RESULTS: The overall rates of deployment involving emergency physicians were found to be positively correlated with the unemployment rate. After adjustment for age, sex, and possible confounders, this correlation was statistically significant (p<0.01). The indirectly standardized rate ratio (IRR) for the overall case-activity rate ranged from 0.841 (95% confidence interval: [0.808; 0.875]) with less than 5% unemployment to 1.212 [1.168; 1.256] with 9.5% unemployment or higher. The same finding was obtained with respect to diagnosis-specific case activity in each of the three main diagnostic categories (cardiovascular, neurological, and pulmonary emergencies), as well as for the respective commonest individual diagnoses (acute coronary syndrome/circulatory arrest [1498 cases], transient ischemic attack/ischemic stroke/intracerebral hemorrhage [1274 cases], and asthma/chronic obstructive pulmonary disease [663 cases]). CONCLUSION: This study shows that the case activity rate of the emergency medical services is significantly higher in socially disadvantaged neighborhoods, both with respect to total numbers and with respect to individual diseases. It demonstrates a problem affecting society as a whole, which should be taken into account in the organization of medical rescue services. PMID- 29467073 TI - The Consumption of New Psychoactive Substances and Methamphetamine. AB - BACKGROUND: The abuse of new psychoactive substances (NPS) and methamphetamine has severe adverse effects. Here we provide the first report of regional patterns in NPS and methamphetamine consumption in Germany, on the basis of epidemiologic data from six federal states (Bavaria, Hamburg, Hesse, North Rhine-Westphalia, Saxony, and Thuringia). METHODS: Data were derived from the 2015 Epidemiological Survey of Substance Abuse (Epidemiologischer Suchtsurvey) and supplemented with additional cases from the federal states that were studied. The numbers of persons included in the representative samples of persons aged 18 to 64 in each state were 1916 (Bavaria), 1125 (Hamburg), 1151 (Hesse), 2008 (North Rhine Westphalia), 1897 (Saxony), and 1543 (Thuringia). Potential risk factors for the lifetime prevalence of consumption were studied by logistic regression. RESULTS: The lifetime prevalence of methamphetamine consumption in the individual states ranged from 0.3% (North Rhine-Westphalia) to 2.0% (Saxony). Thuringia and Saxony displayed values that were significantly higher than average. For NPS, the figures ranged from 2.2% (Bavaria) to 3.9% (Hamburg), but multivariate analysis revealed no statistically significant differences between the states. Higher age and higher educational level were associated with lower consumption of NPS and methamphetamine, while smoking and cannabis use were each associated with higher consumption. CONCLUSION: NPS consumption is equally widespread in all of the federal states studied. Methamphetamine is rarely consumed; its consumption appears to be higher in Saxony and Thuringia. The risk factor analysis reported here should be interpreted cautiously in view of the low case numbers with respect to consumption.

AB - Fecal incontinence is one of the leading causes for the institutionalization of people in the last decades of life, associated with a great psychosocial and economic burden. The literature is scarce in this population group, due to the absence of universally accepted criteria to define "elderly patients" and difficulties in detection and diagnostic. The aim of this article was to conduct a narrative review of the main aspects related to fecal incontinence in older patients, providing management support. Toileting assistance, dietary change, controlling stool consistency and medical treatment can be used to treat these patients. Nevertheless, other therapies, such as biofeedback, neuromodulation or surgical treatment, can be considered in selected patients.

AB - OBJECTIVE: To know organization, management and training in airway (AW) in Spanish Intensive Care Units (ICUs), with special interest in difficult airway (DAW). DESIGN: Descriptive cross-sectional study and chi2 subanalysis, conducted through a national survey from november 1th to december 15th, 2016. With the SEMICYUC's support, an online questionnaire of 27 items was sent to 179 ICUs. SETTING: ICUs of public, private centers, and consortia. RESULTS: In total, 101 units responded (56.4%), corresponding to 1,827 beds and almost 95,000 incomes/year. The 85.1% are public hospitals, and 83.2% had residents. Of the responders, 22.8% don't use routinely AW assessment scales, being the most frequently used the Cormack-Mallampati association (35.6%). There's not intubation (IOT) protocol in 77.2%, nor DAW protocol in 75.2%. An 82.2% have a DAW cart. The 48.5% have training in IOT, and in VAD 53.5%. Having a DAW expert is significantly associated with greater training in IOT (60% vs. 39.3%; P=.03), DAW (64.4% vs. 44.6%; P=.04), and more AW protocols (73.4% vs. 37.5%; P=.000). Having an specific guideline for DAW management in UCI is considered necessary in 99%. CONCLUSIONS: There is room for improvement in AW management. It's necessary to identify an expert in DAW in each Unit, and the development of an specific guideline for DAW management in critical care. PMID- 29467083 TI - Bilateral hydrosalpinx in patients with Hirschsprung's disease. AB - PURPOSE: Hirschsprung's disease (HD) is uncommon in females. There are very few reports on the patients' obstetric and gynecological outcome. Hydrosalpinx causes pain and infertility. It is rare in nonsexually active teenagers. It may be because of an intrinsic disease of the fallopian tubes or secondary to surgery. AIM: to describe the relationship between hydrosalpinx and HD or its surgical approach; to report the impact of bilateral hydrosalpinx on fertility in HD. METHODS: The records of all females with HD since 1980 were reviewed. Only patients who reached menarche were included. Prevalence of hydrosalpinx and hydrosalpinx-free survival were compared after abdominoperineal (A) or transanal (T) surgery. Treatment for hydrosalpinx was reviewed. RESULTS: Seventeen out of 27 patients had reached menarche (Group A: 13 patients; Group T: 4 patients). Five patients in group A and none in group T presented bilateral hydrosalpinx (p=0.261). There were no statistical differences in hydrosalpinx-free survival between groups (p=0.344). Hydrosalpinx treatment: two bilateral and one unilateral salpingectomy, one pyosalpinx evacuation and one untreated. Three patients had conception desire: one has children; two are on IVF program. CONCLUSION: An association between hydrosalpinx and HD was observed. The development of hydrosalpinx was not associated with surgical approach in our study. Females with HD should have a gynecological follow-up for the development of hydrosalpinx, which can impair fertility. LEVEL OF EVIDENCE: Level III, retrospective comparative study. PMID- 29467084 TI - [Social determinants of health at distinct levels by gender: education and household in Spain]. AB - OBJECTIVE: To explore from a gender perspective the association with subjective health of the interaction between education and household arrangements within the framework of social determinants of health placed at the micro and mezzo levels. METHODS: The data comes from the Spanish sample of the European Union Statistics on Income and Living Conditions for 2014. Independent logistic regression models for men and women were run to analyze the association with subjective health of the interaction between education and household arrangements. An additive model was run to assess possible advantages over the interaction approach. RESULTS: The interaction models show a lower or even no significant effect on health of household arrangements usually negatively associated with health among individuals with high education, displaying specific patterns according to sex. CONCLUSIONS: Health profiles of women and men are more precisely drawn if both social determinants of health are combined. Among the women, the important role was confirmed of both social determinants of health in understanding their health inequalities. Among the men, mainly those with low educational achievement, the interaction revealed that the household was a more meaningful social determinant of health. This could enable the definition of more efficient public policies to reduce health and gender inequalities. PMID- 29467085 TI - Persistence of bacterial DNA in orthopedic infections. AB - Polymerase chain reaction (PCR) has been proposed as a method to identify bacteria in clinical samples because it is more sensitive than culture techniques and can produce results rapidly. However, PCR can detect DNA from dead cells and thus cannot distinguish between live and dead cells in a tissue sample. Killed Staphylococcus aureus cells were implanted into the femurs and knee joints of rats to determine the length of time that DNA from dead cells is detectable in a living animal under conditions similar to common orthopedic infections. In the joint infection model studied here, the DNA from the dead planktonic bacteria was detected using PCR immediately after injection or 24 h later, but was undetectable 48 and 72 h after injection. In the biofilm implanted-device model studied, the DNA from these dead biofilm cells was detected by PCR immediately after implantation and at 24 h, but not at 48 or 72 h. Thus, our results indicate that DNA from dead cells does not persist in these animal model systems for more than 2 days, which should reduce concerns about possible false positive results using molecular DNA-based techniques for the detection of pathogens. PMID- 29467086 TI - The application of moving bed bio-reactor (MBBR) in commercial laundry wastewater treatment. AB - Large, laboratory scale biological treatment tests of real industrial wastewater, generated in a large industrial laundry facility, was conducted from October 2014 to January 2015. This research sought to develop laundry wastewater treatment technology which included tests of a two-stage Moving Bed Bio Reactor (MBBR); this had two reactors, was filled with carriers Kaldnes K5 (specific area - 800 m2/m3) and were realized in aerobic condition. Operating on site, in the laundry, reactors were fed actual wastewater from the laundry retention tank. The laundry wastewater contained mainly surfactants and impurities originating from washed fabrics; a solution of urea to supplement nitrogen content and a solution of acid to correct pH were added. The daily flow of raw wastewater Qd varied from 0.6-1.0 m3/d. Wastewater quality indicators showed that the reduction of pollutants was obtained: BOD5 by 95-98%, COD by 89-94%, the sum of anionic and nonionic surfactants by 85-96%. The quality of the purified wastewater after the start-up period met legal requirements regarding the standards for wastewater discharged into the environment. PMID- 29467087 TI - Simulated internal jugular vein cannulation using a needle-guiding device. AB - BACKGROUND: Using a two-dimensional ultrasound-guided approach does not guarantee success during the first attempt at internal jugular vein cannulation. Our randomized, parallel simulation study examined whether a new disposable device could improve the success rate of the first attempt at ultrasound-guided internal jugular vein cannulation of a simulated internal jugular vein. METHODS: Eighty eight participants were randomized to perform needle insertion for internal jugular vein cannulation of a phantom using the ultrasound-guided approach with (case group) or without (control group) this new device. The primary outcome was the success rate of the first attempt. The secondary outcome was the frequency of mechanical complications such as arterial puncture and posterior wall puncture, procedure time, and level of difficulty. RESULTS: Among 44 participants using the device, 33 (75.0%) achieved successful cannulation on the first attempt. However, only 12 (27.3%) of the 44 participants not using the device recorded success during the first attempt (risk difference, 0.477; 95% confidence interval [CI] 0.294-0.661; P<0.001). The number of attempts was significantly lower (risk difference, -3.955; 95% CI, -5.014 to -3.712; P<0.001) when participants performed cannulation with the device (1.63+/-1.71) than without the device (5.59+/-5.78). Our study also showed that participants were comfortable when performing the ultrasound-guided approach with the new device (risk difference, 1.955; 95% CI, -2.016 to -1.493; P<0.0001). CONCLUSIONS: The new disposable device was effective for successful first attempts at needle insertion during ultrasound-guided internal jugular vein cannulation. Future clinical trials are needed to assess the effectiveness of this device. PMID- 29467088 TI - Do Reduced Copayments Affect Mortality after Surgery due to Stroke? An Interrupted Time Series Analysis of a National Cohort Sampled in 2003-2012. AB - BACKGROUND: The South Korean government introduced a policy in 2 phases, in September 2005 and in January 2010, for reducing copayments for patients with critical diseases, including stroke, to prevent excessive medical expenditures and to ease economic barriers. Previous studies of the effect of this policy were focused primarily on cancer. Therefore, we investigated the relationship between this policy and 1-year mortality after surgery among patients with stroke. METHODS: We used data from the Korean National Health Insurance sampling cohort (n = 2173 in 2003-2012) and performed an interrupted time series analysis. RESULTS: Approximately 26% of the patients died within 1 year after surgery. The time trends after reducing copayments from 10% to 5% (phase 2) were inversely associated with risk of 1-year mortality (relative risk = .855, 95% confidence interval: .749-.975; P = .0196). In addition, this inverse association was greater in patients with low incomes, of older ages, and with higher Charlson comorbidity indices. CONCLUSIONS: The introduction of a policy for reducing copayments to ease excessive cost burdens for patients with stroke was positively associated with a reduced risk of 1-year mortality after surgical treatment due to stroke. On the basis of our results, health policy makers should make an effort to identify vulnerable populations and to overcome economic barriers for providing effective alternatives to ensure patients receive optimal health care. PMID- 29467089 TI - ? PMID- 29467090 TI - Chin Position: to treat or not to treat. AB - This study was conducted to compare the mean preference scores for orthodontic treatment need, considering the chin position, amongst orthodontists, orthodontic patients and their parents. Male and female profile silhouettes were prepared by changing their chin prominence using Adobe Photoshop 7 with zero degree meridian as line of reference. Rating of these silhouettes was done by the three groups of raters (orthodontists, orthodontic patients and their parents) on a scale of four with one being no need of treatment and four being severe need of treatment. There was a statistically significant difference seen amongst orthodontists and the orthodontic patients and also amongst the orthodontist and the orthodontic patient's parents for the 2mm and 4mm chin position with orthodontists scoring a higher need of treatment as compared to the patients and parents.

AB - PURPOSE: The aim of this study was to assess differences in interreader variability among radiologists after the implementation of a computer-assisted reporting (CAR) tool for the interpretation of degenerative disc disease on lumbar spine MRI. METHODS: Thirty lumbar spine MRI examinations were selected from the radiology database. Five fellowship-trained musculoskeletal radiologists evaluated each L4-L5 disc in a blinded fashion and reported the findings using a traditional free dictation approach. One month later, they reinterpreted the same discs using a web browser-based CAR tool in the same blinded fashion. The degrees of central canal stenosis, neural foraminal stenosis, and facet joint osteoarthritis; presence or absence of lateral recess stenosis; types of disc bulge or herniation; and herniation location using both methods were recorded. Percentage disagreement among the radiologists for each variable was calculated and compared using the Wilcoxon signed rank test. RESULTS: There was a statistically significant decrease among the five radiologists in percentage disagreement for neural foraminal stenosis (46% versus 35%, P = .0146) and facet joint osteoarthritis (45% and 22%, P < .0001) for reports created by free dictation compared with those created using the CAR tool. There was no statistically significant difference in interreader variability for the assessment of central canal stenosis, lateral recess effacement, disc herniation, disc bulge, or herniation location. CONCLUSIONS: Implementation of a CAR tool for the interpretation of degenerative changes on lumbar spine MRI decreases interreader variability in the assessment of neural foraminal stenosis and facet joint osteoarthritis.

PMID- 29467096 TI - Predictive effect of hyperuricemia on left atrial stasis in non-valvular atrial fibrillation patients. AB - OBJECTIVES: To investigate the relationship between hyperuricemia and left atrial thrombus (LAT)/spontaneous echo contrast (SEC) and to determine the predictive value of hyperuricemia in non-valvular (NV) atrial fibrillation (AF) patients. METHODS: The study retrospectively reviewed 1198 consecutive patients (male 801, female 397, and mean age of 56.84 +/- 12.22) who were diagnosed with AF and accepted transesophageal echocardiography (TEE) prior to catheter ablation, appendage occlusion and electrical cardioversion using a single-center database. The clinical baseline characteristics were collected from medical record review and analyzed. Patients were categorized into an LAT/SEC group and a normal group. RESULTS: According to the TEE examination, there were 97 (8.1%) patients with abnormality; of these, 49 were with LAT and 48 with SEC. The mean serum uric acid (SUA) level and hyperuricemia proportion were markedly higher in patients with LAT/SEC. The significant predictive effect was observed in the SUA level (OR = 1.006) and hyperuricemia (OR = 2.04). After adjustment for persistent/permanent AF, age, gender, LA dimension > 40 mm, previous stroke, hypertension and diabetes, the SUA level (OR = 1.004) and hyperuricemia (OR = 1.69) were independent predictors for LAT/SEC. The SUA level (OR = 1.004) and hyperuricemia (OR = 1.69) were independent predictors for LAT/SEC, Further subgroup analysis in different CHA2DS2-VASc categories, it might be helpful to refine the LAT/SEC risk via combination area CHA2DS2-VASc score and hyperuricemia, especially in those with CHA2DS2-VASc score < 2. CONCLUSIONS: The SUA level and hyperuricemia proportion are closely associated with LA stasis. Hyperuricemia might independently predict and refine LA stasis risk among NVAF patients, especially in those with CHA2DS2-VASc score < 2. PMID- 29467097 TI - Vasovagal responses during cryoballoon pulmonary vein isolation in paroxysmal atrial fibrillation predict favorable mid-term outcomes. AB - BACKGROUND: Vasovagal responses (VR) encountered during radiofrequency pulmonary vein isolation (PVI) in paroxysmal atrial fibrillation (PAF) suggest ablation of the atrial tissue subjacent to the ganglionic plexi (GP) and confer durability of PVI. OBJECTIVE: We hypothesized that VR during cryoballoon PVI (CB-PVI) in PAF can predict mid-term AF recurrence. METHODS: We enrolled 39 patients who underwent PVI using 2nd generation cryoballoon for PAF from November 2014 to July 2016. We evaluated the long term outcomes for those who had VR during index procedure. RESULTS: A total of 39 patients (76% male, mean age 57 +/- 9 years) underwent CB-PVI for PAF and 66.67% (26/39) had VR. VR was frequently observed in the LSPV (100%), followed by RSPV (64%), LIPV (60%), and less frequently, RIPV (28%). Overall, the mean difference in the HR and SBP, and the relative differences in the HR and SBP were observed during CB-PVI in the LSPV (mean difference in HR, p < 0.001; mean difference in SBP, p < 0.001; relative difference in HR, p < 0.001); relative difference in SBP, p < 0.001). After PVI, 22/26 (84.62%) and 5/13 (38.46%) of patients in the VR and NVR group, respectively, maintained SR at 14 +/- 6 months follow-up. The Kaplan-Meier analysis showed statistical difference in favor of patients with VR during CB-PVI (log rank p < 0.01) with a better mid-term outcome. CONCLUSION: In a small cohort of patients, VR during CB-PVI in PAF is a surrogate marker for ablation of atrial tissue subjacent to the GP and predicts a favorable mid-term outcome for AF recurrence. PMID- 29467099 TI - !PrEP Ya! Latin America wants PrEP, and Brazil leads the way. PMID- 29467098 TI - Retention, engagement, and adherence to pre-exposure prophylaxis for men who have sex with men and transgender women in PrEP Brasil: 48 week results of a demonstration study. AB - BACKGROUND: PrEP Brasil was a demonstration study to assess feasibility of daily oral tenofovir diphosphate disoproxil fumarate plus emtricitabine provided at no cost to men who have sex with men (MSM) and transgender women at high risk for HIV within the Brazilian public health system. We report week 48 pre-exposure prophylaxis (PrEP) retention, engagement, and adherence, trends in sexual behaviour, and incidence of HIV and sexually transmitted infections in this study cohort. METHODS: PrEP Brasil was a 48 week, open-label, demonstration study that assessed PrEP delivery at three referral centres for HIV prevention and care in Rio de Janeiro, Brazil (Fundacao Oswaldo Cruz), and Sao Paulo, Brazil (Universidade de Sao Paulo and Centro de Referencia e Treinamento em DST e AIDS). Eligible participants were MSM and transgender women who were HIV negative, aged at least 18 years, resident in Rio de Janeiro or Sao Paulo, and reported one or more sexual risk criteria in the previous 12 months (eg, condomless anal sex with two or more partners, two or more episodes of anal sex with an HIV-infected partner, or history of sexually transmitted infection [STI] diagnosis). Participants were seen at weeks 4, 12, 24, 36, and 48 for PrEP provision, clinical and laboratory evaluation, and HIV testing. Computer-assisted self interviews were also done at study visits 12, 24, 36, and 48, and assessed sexual behaviour and drug use. PrEP retention was defined by attendance at the week 48 visit, PrEP engagement was an ordinal five-level variable combining presence at the study visit and drug concentrations, and PrEP adherence was evaluated by measuring tenofovir diphosphate concentrations in dried blood spots. Logistic regression models were used to quantify the association of variables with high adherence (>=4 doses per week). The study is registered with ClinicalTrials.gov, number NCT01989611. FINDINGS: Between April 1, 2014, and July 8, 2016, 450 participants initiated PrEP, 375 (83%) of whom were retained until week 48. At week 48, 277 (74%) of 375 participants had protective drug concentrations consistent with at least four doses per week: 183 (82%) of 222 participants from Sao Paulo compared with 94 (63%) of 150 participants from Rio de Janeiro (adjusted odds ratio 1.88, 95% CI 1.06-3.34); 119 (80%) of 148 participants who reported sex with HIV-infected partners compared with 158 (70%) of 227 participants who did not (1.78, 1.03-3.08); 67 (87%) of 77 participants who used stimulants compared with 210 (71%) of 298 participants who did not (2.23, 1.02 4.92); and 232 (80%) of 289 participants who had protective concentrations of tenofovir disphosphate at week 4 compared with 42 (54%) of 78 participants who did not (3.28, 1.85-5.80). Overall, receptive anal sex with the last three partners increased from 45% at enrolment to 49% at week 48 (p=0.17), and the mean number of sexual partners in the previous 3 months decreased from 11.4 (SD 28.94) at enrolment to 8.3 (19.55) at week 48 (p<0.0013). Two individuals seroconverted during follow-up (HIV incidence 0.51 per 100 person-years, 95% CI 0.13-2.06); both of these patients had undetectable tenofovir concentrations at seroconversion. INTERPRETATION: Our results support the effectiveness and feasibility of PrEP in a real-world setting. Offering PrEP at public health-care clinics in a middle-income setting can retain high numbers of participants and achieve high levels of adherence without risk compensation in the investigated populations.

PMID- 29467101 TI - Ultrasound screening for complications in twin pregnancy. AB - In the decades since the introduction of ultrasound into routine obstetric practice, the advantages of ultrasound have moved beyond the simple ability to identify multiple pregnancies antenatally to the possibility of screening them for fetal anomalies, pre-eclampsia, preterm birth, and the complications specific to monochorionic pregnancies. Screening studies have often excluded twins because physiological differences impact on the validity and sensitivity of the screening tests in routine use in singletons, and therefore, the evidence of screening performance in multiple pregnancy lags behind the evidence from singleton pregnancies. In general, most pregnancy complications are more common in twin pregnancy, but screening tests are less accurate or well validated. In this review article we present the current state of the evidence and avenues for future research relating to the use of ultrasound and screening for complications in twin pregnancies, including the monochorionicity-related pathologies, such as twin-twin transfusion syndrome, selective growth restriction, twin anaemia polycythaemia sequence and twin reversed arterial perfusion sequence. PMID- 29467100 TI - Epileptogenesis in neonatal brain. AB - Epilepsy is a chronic neurological disorder affecting 65 million people worldwide. The etiologies of seizures can often be identified as genetic, metabolic, structural, immunologic or infectious, but in many cases the cause is unknown with the current diagnostic tools. Epileptogenesis is a process during which genetic or other acquired etiologies/insults lead to functional, structural, or network reorganization changes in the brain that may lead to the development of, or progression of, spontaneous seizures. During development, there are continuous changes in the structure, function, and network operation that also show sex specificity, which may alter the mechanisms underlying the generation of seizures (ictogenesis) and epileptogenesis. Understanding the mechanisms of early life epileptogenesis will enable the development of rationally designed age- and sex-appropriate therapies that would improve the overall quality of patients' lives. Here, we discuss some of these processes that may affect seizure generation and epileptogenesis in the neonatal brain. PMID- 29467102 TI - Acute symptomatic neonatal seizures in preterm neonates: etiologies and treatments. AB - Acute symptomatic neonatal seizures in preterm newborns are a relevant clinical challenge due to the presence of many knowledge gaps. Etiology-wise, acute symptomatic seizures have an age-specific epidemiology, with intraventricular hemorrhage and its complications representing the first cause in extremely and very preterm neonates, whereas other etiologies have similar occurrence rates as in full-term infants. Specific treatment strategies for the premature neonates are not yet available. Studies suggest a similarly low response rate with even more unfavorable prognosis than in full-term infants. Pharmacodynamic and pharmacokinetic changes are likely under way during the preterm period, with the potential to affect both effectiveness and safety of antiepileptic drugs in these patients. However, due to the lack of clear evidence to guide prioritization of second-line drugs, off-label medications are frequently indicated by review papers and flow-charts, and are prescribed in clinical practice. We therefore conclude by exploring potential future lines of research. PMID- 29467103 TI - Designing a trial for neonatal seizure treatment. AB - Neonatal seizures are widely considered a neurological emergency with a need for prompt treatment, yet they are known to present a highly elusive target for bedside clinicians. Recent studies have suggested that the design of a neonatal seizure treatment trial will profoundly influence the sample size, which may readily increase to hundreds or even thousands as the achieved effect size diminishes to clinical irrelevance. The self-limiting and rapidly resolving nature of neonatal seizures diminishes the measurable treatment effect every hour after seizure onset and any effect may potentially be confused with spontaneous resolution, precluding the value of many observational studies. The large individual variability in seizure occurrence over time and between etiologies challenges group comparisons, while the absence of clinical signs mandates quantification of seizure occurrence with continuous multi-channel EEG monitoring. A biologically sound approach that views neonatal seizures as a functional cot-side biomarker rather than an object to treat can overcome these challenges. PMID- 29467104 TI - Estimating Acute Cardiovascular Effects of Ambient PM2.5 Metals. AB - BACKGROUND: Few epidemiologic studies have investigated health effects of water soluble fractions of PM2.5 metals, the more biologically accessible fractions of metals, in their attempt to identify health-relevant components of ambient PM2.5. OBJECTIVES: In this study, we estimated acute cardiovascular effects of PM2.5 components in an urban population, including a suite of water-soluble metals that are not routinely measured at the ambient level. METHODS: Ambient concentrations of criteria gases, PM2.5, and PM2.5 components were measured at a central monitor in Atlanta, Georgia, during 1998-2013, with some PM2.5 components only measured during 2008-2013. In a time-series framework using Poisson regression, we estimated associations between these pollutants and daily counts of emergency department (ED) visits for cardiovascular diseases in the five-county Atlanta area. RESULTS: Among the PM2.5 components we examined during 1998-2013, water soluble iron had the strongest estimated effect on cardiovascular outcomes [RR=1.012 (95% CI: 1.005, 1.019), per interquartile range increase (20.46ng/m3)]. The associations for PM2.5 and other PM2.5 components were consistent with the null when controlling for water-soluble iron. Among PM2.5 components that were only measured during 2008-2013, water-soluble vanadium was associated with cardiovascular ED visits [RR=1.012 (95% CI: 1.000, 1.025), per interquartile range increase (0.19ng/m3)]. CONCLUSIONS: Our study suggests cardiovascular effects of certain water-soluble metals, particularly water-soluble iron. The observed associations with water-soluble iron may also point to certain aspects of traffic pollution, when processed by acidifying sulfate, as a mixture harmful for cardiovascular health. https://doi.org/10.1289/EHP2182. PMID- 29467105 TI - Metal Concentrations in e-Cigarette Liquid and Aerosol Samples: The Contribution of Metallic Coils. AB - BACKGROUND: Electronic cigarettes (e-cigarettes) generate an aerosol by heating a solution (e-liquid) with a metallic coil. Whether metals are transferred from the coil to the aerosol is unknown. OBJECTIVE: Our goal was to investigate the transfer of metals from the heating coil to the e-liquid in the e-cigarette tank and the generated aerosol. METHODS: We sampled 56 e-cigarette devices from daily e-cigarette users and obtained samples from the refilling dispenser, aerosol, and remaining e-liquid in the tank. Aerosol liquid was collected via deposition of aerosol droplets in a series of conical pipette tips. Metals were reported as mass fractions (MUg/kg) in liquids and converted to mass concentrations (mg/m3) for aerosols. RESULTS: Median metal concentrations (MUg/kg) were higher in samples from the aerosol and tank vs. the dispenser (all p<0.001): 16.3 and 31.2 vs. 10.9 for Al; 8.38 and 55.4 vs. <0.5 for Cr; 68.4 and 233 vs. 2.03 for Ni; 14.8 and 40.2 vs. 0.476 for Pb; and 515 and 426 vs. 13.1 for Zn. Mn, Fe, Cu, Sb, and Sn were detectable in most samples. Cd was detected in 0.0, 30.4, and 55.1% of the dispenser, aerosol, and tank samples respectively. Arsenic was detected in 10.7% of dispenser samples (median 26.7MUg/kg) and these concentrations were similar in aerosol and tank samples. Aerosol mass concentrations (mg/m3) for the detected metals spanned several orders of magnitude and exceeded current health based limits in close to 50% or more of the samples for Cr, Mn, Ni, and Pb. CONCLUSIONS: Our findings indicate that e-cigarettes are a potential source of exposure to toxic metals (Cr, Ni, and Pb), and to metals that are toxic when inhaled (Mn and Zn). Markedly higher concentrations in the aerosol and tank samples versus the dispenser demonstrate that coil contact induced e-liquid contamination. https://doi.org/10.1289/EHP2175. PMID- 29467106 TI - Ultrafine and Fine Particle Number and Surface Area Concentrations and Daily Cause-Specific Mortality in the Ruhr Area, Germany, 2009-2014. AB - BACKGROUND: Although epidemiologic studies have shown associations between particle mass and daily mortality, evidence on other particle metrics is weak. OBJECTIVES: We investigated associations of size-specific particle number concentration (PNC) and lung-deposited particle surface area concentration (PSC) with cause-specific daily mortality in contrast to PM10. METHODS: We used time series data (March 2009-December 2014) on daily natural, cardiovascular, and respiratory mortality (NM, CVM, RM) of three adjacent cities in the Ruhr Area, Germany. Size-specific PNC (electric mobility diameter of 13.3-750 nm), PSC, and PM10 were measured at an urban background monitoring site. In single- and multipollutant Poisson regression models, we estimated percentage change (95% confidence interval) [% (95% CI)] in mortality per interquartile range (IQR) in exposure at single-day (0-7) and aggregated lags (0-1, 2-3, 4-7), accounting for time trend, temperature, humidity, day of week, holidays, period of seasonal population decrease, and influenza. RESULTS: PNC100-750 and PSC were highly correlated and had similar immediate (lag0-1) and delayed (lag4-7) associations with NM and CVM, for example, 1.12% (95% CI: 0.09, 2.33) and 1.56% (95% CI: 0.22, 2.92) higher NM with IQR increases in PNC100-750 at lag0-1 and lag4-7, respectfully, which were slightly stronger then associations with IQR increases in PM10. Positive associations between PNC and NM were strongest for accumulation mode particles (PNC 100-500 nm), and for larger UFPs (PNC 50-100 nm). Associations between NM and PNC<100 changed little after adjustment for O3 or PM10, but were more sensitive to adjustment for NO2. CONCLUSION: Size-specific PNC (50-500 nm) and lung-deposited PSC were associated with natural and cardiovascular mortality in the Ruhr Area. Although associations were similar to those estimated for an IQR increase in PM10, particle number size distributions can be linked to emission sources, and thus may be more informative for potential public health interventions. Moreover, PSC could be used as an alternative metric that integrates particle size distribution as well as deposition efficiency. https://doi.org/10.1289/EHP2054. PMID- 29467107 TI - Associations between Personal Care Product Use Patterns and Breast Cancer Risk among White and Black Women in the Sister Study. AB - BACKGROUND: Many personal care products include chemicals that might act as endocrine disruptors and thus increase the risk of breast cancer. OBJECTIVE: We examined the association between usage patterns of beauty, hair, and skin-related personal care products and breast cancer incidence in the Sister Study, a national prospective cohort study (enrollment 2003-2009). METHODS: Non-Hispanic black (4,452) and white women (n=42,453) were examined separately using latent class analysis (LCA) to identify groups of individuals with similar patterns of self-reported product use in three categories (beauty, skin, hair). Multivariable Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for associations between product use and breast cancer incidence. RESULTS: A total of 2,326 women developed breast cancer during follow up (average follow-up=5.4y). Among black women, none of the latent class hazard ratios was elevated, but there were <100 cases in any category, limiting power. Among white women, those classified as "moderate" and "frequent" users of beauty products had increased risk of breast cancer relative to "infrequent" users [HR=1.13 (95% CI: 1.00, 1.27) and HR=1.15 (95% CI: 1.02, 1.30), respectively]. Frequent users of skincare products also had increased risk of breast cancer relative to infrequent users [HR=1.13 (95% CI: 1.00, 1.29)]. None of the hair product classes was associated with increased breast cancer risk. The associations with beauty and skin products were stronger in postmenopausal women than in premenopausal women, but not significantly so. CONCLUSIONS: This work generates novel hypotheses about personal care product use and breast cancer risk. Whether these results are due to specific chemicals or to other correlated behaviors needs to be evaluated. https://doi.org/10.1289/EHP1480. PMID- 29467109 TI - What's in the Mix?

AB - BACKGROUND: Increasing evidence links higher particulate matter (PM) air pollution exposure to late-life cognitive impairment. However, few studies have considered associations between direct estimates of long-term past exposures and brain MRI findings indicative of neurodegeneration or cerebrovascular disease. OBJECTIVE: Our objective was to quantify the association between brain MRI findings and PM exposures approximately 5 to 20 y prior to MRI in the Atherosclerosis Risk in Communities (ARIC) study. METHODS: ARIC is based in four U.S. sites: Washington County, Maryland; Minneapolis suburbs, Minnesota; Forsyth County, North Carolina; and Jackson, Mississippi. A subset of ARIC participants underwent 3T brain MRI in 2011-2013 (n=1,753). We estimated mean exposures to PM with an aerodynamic diameter less than 10 or 2.5MUm (PM10 and PM2.5) in 1990 1998, 1999-2007, and 1990-2007 at the residential addresses of eligible participants with MRI data. We estimated site-specific associations between PM and brain MRI findings and used random-effect, inverse variance-weighted meta analysis to combine them. RESULTS: In pooled analyses, higher mean PM2.5 and PM10 exposure in all time periods were associated with smaller deep-gray brain volumes, but not other MRI markers. Higher PM2.5 exposures were consistently associated with smaller total and regional brain volumes in Minnesota, but not elsewhere. CONCLUSIONS: Long-term past PM exposure in was not associated with markers of cerebrovascular disease. Higher long-term past PM exposures were associated with smaller deep-gray volumes overall, and higher PM2.5 exposures were associated with smaller brain volumes in the Minnesota site. Further work is needed to understand the sources of heterogeneity across sites. https://doi.org/10.1289/EHP2152.

PMID- 29467112 TI - Interobserver agreement between senior radiology resident, neuroradiology fellow, and experienced neuroradiologist in the rating of Alberta Stroke Program Early Computed Tomography Score (ASPECTS). AB - PURPOSE: The distribution of ischemic changes caused by infarction of the middle cerebral artery (MCA) territories is usually measured using the Alberta Stroke Program Early Computed Tomography Score (ASPECTS). The first interpreter of the brain computed tomography (CT) in the emergency department is the on-call radiology resident. The primary objective of this study was to describe the agreement of the ASPECTS performed retrospectively by the resident compared with expert raters. The second objective was to ascertain the appropriate window setting for early detection of acute ischemic stroke and good interobserver agreement between the interpreters. METHODS: We identified consecutive patients presenting with hemiparesis or aphasia at the emergency department who underwent brain CT and CT angiography. Each scan was rated using ASPECTS by senior radiology resident, neuroradiology fellow, and later by consensus between two expert raters. Statistical analysis included determination of Cohen's kappa (kappa) coefficient and intraclass correlation coefficient (ICC). RESULTS: A total of 43 patients met our study criteria. Interobserver agreements for ASPECTS varied from 0.486 to 0.678 in Cohen's kappa coefficient between consensus of two neuroradiologists and a neuroradiology fellow, and from 0.198 to 0.491 for consensus between two neuroradiologists and a senior radiology resident. ICC among three raters (expert consensus, neuroradiology fellow, and senior radiology resident), was very good when 8 HU window width and 32 HU center level setting was used. CONCLUSION: ASPECTS varied among raters. However, when using a narrowed window setting for interpretation, interobserver agreement improved. PMID- 29467113 TI - Accuracy of the ADNEX MR scoring system based on a simplified MRI protocol for the assessment of adnexal masses. AB - PURPOSE: We aimed to evaluate the ADNEX MR scoring system for the prediction of adnexal mass malignancy, using a simplified magnetic resonance imaging (MRI) protocol. METHODS: In this prospective study, 200 patients with 237 adnexal masses underwent MRI between February 2014 and February 2016 and were followed until February 2017. Two radiologists calculated ADNEX MR scores using an MRI protocol with a simplified dynamic study, not a high temporal resolution study, as originally proposed. Sensitivity, specificity, positive and negative predictive values, likelihood ratios, and the area under the receiver operating characteristic curve were calculated (cutoff for malignancy, score >= 4). The reference standard was histopathologic diagnosis or imaging findings during >12 months of follow-up. RESULTS: Of 237 lesions, 79 (33.3%) were malignant. The ADNEX MR scoring system, using a simplified MRI protocol, showed 94.9% (95% confidence interval [CI], 87.5%-98.6%) sensitivity and 97.5% (95% CI, 93.6% 99.3%) specificity in malignancy prediction; it was thus highly accurate, like the original system. The level of interobserver agreement on simplified scoring was high (kappa = 0.91). CONCLUSION: In a tertiary cancer center, the ADNEX MR scoring system, even based on a simplified MRI protocol, performed well in the prediction of malignant adnexal masses. This scoring system may enable the standardization of MRI reporting on adnexal masses, thereby improving communication between radiologists and gynecologists. PMID- 29467114 TI - Adrenal venous sampling: the learning curve of a single interventionalist with 282 consecutive procedures. AB - PURPOSE: Primary aldosteronism (PA) is a common cause of secondary hypertension. Adrenal venous sampling (AVS) is the gold standard for assessing laterality of PA, which is of paramount importance to decide adequate treatment. AVS is a technically complicated procedure with success rates ranging between 30% and 96%. The aim of this study was to investigate the success rate of AVS over time, performed by a single interventionalist. METHODS: This was a retrospective study based on consecutive AVS procedures performed by a single operator between September 2005 and June 2016. Data on serum concentrations of aldosterone and cortisol from right and left adrenal vein, inferior vena cava, and peripheral vein were collected and selectivity index (SI) calculated. Successful AVS was defined as SI > 5. RESULTS: In total, 282 AVS procedures were performed on 269 patients, 168 men (62%) and 101 women (38%), with a mean age of 55+/-11 years (range, 26-78 years). Out of 282 AVS procedures, 259 were successful, giving an overall success rate of 92%. The most common reason for failure was inability to localize the right adrenal vein (n=16; 76%). The success rates were 63%, 82%, and 94% during the first, second, and third years, respectively. During the last 8 years the success rate was 95%, and on average 27 procedures were performed annually. CONCLUSION: Satisfactory AVS success rate was achieved after approximately 36 procedures and satisfactory success rate was maintained by performing approximately 27 procedures annually. AVS should be limited to few operators that perform sufficiently large number of procedures to achieve, and maintain, satisfactory AVS success rate. PMID- 29467115 TI - The pancreatic and extrapancreatic manifestations of IgG4-related disease. AB - The association between immunoglobulin IgG4 and autoimmune pancreatitis was first shown in 2001. Since then many previously established fibrosclerotic diseases demonstrating synchronous or metachronous multiorgan involvement have been included within the ambit of IgG4-related disease. Diagnostic criteria have been proposed involving 1) serum IgG4 level elevated beyond 135 mg/dL, 2) IgG4+ to IgG+ plasma cell ratio > 40% and >10 IgG4+ cells per high power field of biopsy sample and 3) a constellation of imaging features which involve a variety of organ systems. We present a pictorial essay demonstrating the spectrum of imaging findings for IgG4-related disease, including dacryosialadenitis, variety of renal lesions, tumefactive thickening of the extraocular muscles and orbital nerve, sclerosing cholangitis, and type I pancreatitis. Imaging plays an important role in diagnosis, screening for multiorgan involvement, and follow-up of the disease.

PMID- 29467117 TI - The Effects of Bougie Diameters on Tissue Oxygen Levels After Sleeve Gastrectomy: A Randomized Experimental Trial AB - Background: Staple-line leak is the most frightening complication of laparoscopic sleeve gastrectomy and several predisposing factors such as using improper staple sizes regardless of gastric wall thickness, narrower bougie diameter and ischemia of the staple line are asserted. Aims: To evaluate the effects of different bougie diameters on tissue oxygen partial pressure at the esophagogastric junction after sleeve gastrectomy. Study Design: A randomized and controlled animal experiment with 1:1:1:1 allocation ratio. Methods: Thirty-two male Wistar Albino rats were randomly divided into 4 groups of 8 each. While 12-Fr bougies were used in groups 1 and 3, 8-Fr bougies were used in groups 2 and 4. Fibrin sealant application was also carried out around the gastrectomy line after sleeve gastrectomy in groups 3 and 4. Burst pressure of gastrectomy line, tissue oxygen partial pressure and hydroxyproline levels at the esophagogastric junction were measured and compared among groups. Results: Mortality was detected in 2 out of 32 rats (6.25%) and one of them was in group 2 and the cause of this mortality was gastric leak. Gastric leak was detected in 2 out of 32 rats (6.25%). There was no significant difference in terms of burst pressures, tissue oxygen partial pressure and tissue hydroxyproline levels among the 4 groups. Conclusion: The use of narrower bougie along with fibrin sealant has not had a negative effect on tissue perfusion and wound healing. PMID- 29467118 TI - Type 2 Diabetes Education and Support in a Virtual Environment: A Secondary Analysis of Synchronously Exchanged Social Interaction and Support. AB - BACKGROUND: Virtual environments (VEs) facilitate interaction and support among individuals with chronic illness, yet the characteristics of these VE interactions remain unknown. OBJECTIVE: The objective of this study was to describe social interaction and support among individuals with type 2 diabetes (T2D) who interacted in a VE. METHODS: Data included VE-mediated synchronous conversations and text-chat and asynchronous emails and discussion board posts from a study that facilitated interaction among individuals with T2D and diabetes educators (N=24) in 2 types of sessions: education and support. RESULTS: VE interactions consisted of communication techniques (how individuals interact in the VE), expressions of self-management (T2D-related topics), depth (personalization of topics), and breadth (number of topics discussed). Individuals exchanged support more often in the education (723/1170, 61.79%) than in the support (406/1170, 34.70%) sessions or outside session time (41/1170, 3.50%). Of all support exchanges, 535/1170 (45.73%) were informational, 377/1170 (32.22%) were emotional, 217/1170 (18.55%) were appraisal, and 41/1170 (3.50%) were instrumental. When comparing session types, education sessions predominately provided informational support (357/723, 49.4%), and the support sessions predominately provided emotional (159/406, 39.2%) and informational (159/406, 39.2%) support. CONCLUSIONS: VE-mediated interactions resemble those in face-to face environments, as individuals in VEs engage in bidirectional exchanges with others to obtain self-management education and support. Similar to face-to-face environments, individuals in the VE revealed personal information, sought information, and exchanged support during the moderated education sessions and unstructured support sessions. With this versatility, VEs are able to contribute substantially to support for those with diabetes and, very likely, other chronic diseases. PMID- 29467119 TI - Pre-Exposure Prophylaxis YouTube Videos: Content Evaluation. AB - BACKGROUND: Antiretroviral (ARV) medicines reduce the risk of transmitting the HIV virus and are recommended as daily pre-exposure prophylaxis (PrEP) in combination with safer sex practices for HIV-negative individuals at a high risk for infection, but are underused in HIV prevention. Previous literature suggests that YouTube is extensively used to share health information. While pre-exposure prophylaxis (PrEP) is a novel and promising approach to HIV prevention, there is limited understanding of YouTube videos as a source of information on PrEP. OBJECTIVE: The objective of this study was to describe the sources, characteristics, and content of the most widely viewed PrEP YouTube videos published up to October 1, 2016. METHODS: The keywords "pre-exposure prophylaxis" and "Truvada" were used to find 217 videos with a view count >100. Videos were coded for source, view count, length, number of comments, and selected aspects of content. Videos were also assessed for the most likely target audience. RESULTS: The total cumulative number of views was >2.3 million, however, a single Centers for Disease Control and Prevention video accounted for >1.2 million of the total cumulative views. A great majority (181/217, 83.4%) of the videos promoted the use of PrEP, whereas 60.8% (132/217) identified the specific target audience. In contrast, only 35.9% (78/217) of the videos mentioned how to obtain PrEP, whereas less than one third addressed the costs, side effects, and safety aspects relating to PrEP. Medical and academic institutions were the sources of the largest number of videos (66/217, 30.4%), followed by consumers (63/217, 29.0%), community-based organizations (CBO; 48/217, 22.1%), and media (40/217, 18.4%). Videos uploaded by the media sources were more likely to discuss the cost of PrEP (P<.001), whereas the use of PrEP was less likely to be promoted in videos uploaded by individual consumers (P=.002) and more likely to be promoted in videos originated by CBOs (P=.009). The most common target audience for the videos was gay and bisexual men. CONCLUSIONS: YouTube videos can be used to share reliable PrEP information with individuals. Further research is needed to identify the best practices for using this medium to promote and increase PrEP uptake. PMID- 29467120 TI - Medicaid Becomes the First Third-Party Payer to Cover Passive Remote Monitoring for Home Care: Policy Analysis. AB - BACKGROUND: Recent years have seen an influx of location-tracking, activity monitoring sensors, and Web-cameras to remotely monitor the safety of older adults in their homes and to reduce reliance on in-person assistance. The state of research on these monitoring technologies leaves open crucial financial, social, and ethical cost-benefit questions, which have prevented widespread use. Medicaid is now the first large third-party payer in the United States to pay for these technologies, and their use is likely to increase as states transition to managed long-term services and supports (MLTSS). OBJECTIVES: This is the first study to examine how state Medicaid programs are treating passive remote monitoring technologies. This study identifies (1) which states allow location tracking, sensor systems, and cameras; (2) what policies are in place to track their use; (3) what implementation processes and program monitoring mechanisms are in place; and (4) what related insights Medicaid program stakeholders would like to learn from researchers. METHODS: Interviews were conducted with 43 state, federal, and managed care organization (MCO) Medicaid program stakeholders about how these technologies are used in state waivers serving community-dwelling older adults in 15 states, and what policies are in place to regulate them. The interviews were analyzed by the research team using the framework analysis method for applied policy research. RESULTS: Two-thirds of the states cover location tracking and activity-monitoring sensors and one-third cover cameras, but only 3 states have specific service categories that allow them to track when they are paying for any of these technologies, impeding regulation and understanding of their use at the state and federal level. Consideration of ethical and social risks is limited, and states struggle to understand which circumstances warrant use. They are further challenged by extreme resource restrictions and transitions to MLTSS by MCOs inexperienced in serving this growing "high-need, high-cost" population. CONCLUSIONS: Decisions about Medicaid reimbursement of technologies that have the potential to dramatically alter the way older adults receive supportive services are being made without research on their use, social and ethical implications, or outcomes. At a minimum, new service categories are needed to enable oversight. Participants prioritized 3 research aims to inform practice: (1) determine cost-effectiveness; (2) identify what type of information beneficiaries want to be generated and whom they want it to be shared with; and (3) understand how to support ethical decision making for beneficiaries with cognitive impairment. These findings provide direction for future research and reveal that greater interaction between policy makers and researchers in this field is needed. PMID- 29467121 TI - Clinical Feasibility of Continuously Monitored Data for Heart Rate, Physical Activity, and Sleeping by Wearable Activity Trackers in Patients with Thyrotoxicosis: Protocol for a Prospective Longitudinal Observational Study. AB - BACKGROUND: Thyrotoxicosis is a common disease caused by an excess of thyroid hormones. The prevalence of thyrotoxicosis about 2% and 70-90% of thyrotoxicosis cases are caused by Graves' disease, an autoimmune disease, which has a high recurrence rate when treated with antithyroid drugs such as methimazole or propylthiouracil. The clinical symptoms and signs of thyrotoxicosis include palpitation, weight loss, restlessness, and difficulty sleeping. Although these clinical changes in thyrotoxicosis can be detected by currently available wearable activity trackers, there have been few trials of the clinical application of wearable devices in patients with thyrotoxicosis. OBJECTIVE: The aim of this study is to investigate the clinical applicability of wearable device generated data to the management of thyrotoxicosis. We are analyzing continuously monitored data for heart rate, physical activity, and sleep in patients with thyrotoxicosis during their clinical course after treatment. METHODS: Thirty thyrotoxic patients and 10 control subjects were enrolled in this study at Seoul National University Bundang Hospital. Heart rate, physical activity, and sleep are being monitored using a Fitbit Charge HR or Fitbit Charge 2. Clinical data including anthropometric measures, thyroid function test, and hyperthyroidism symptom scale are recorded. RESULTS: Study enrollment began in December 2016, and the intervention and follow-up phases are ongoing. The results of the data analysis are expected to be available by September 2017. CONCLUSIONS: This study will provide a foundational feasibility trial of the clinical applications of biosignal measurements to the differential diagnosis, prediction of clinical course, early detection of recurrence, and treatment in patients with thyrotoxicosis.

PMID- 29467123 TI - Successful perioperative management in a patient with factor XI deficiency. AB - Factor XI (FXI) deficiency is an autosomal disorder which manifests as bleeding of varying severity. While homozygotes typically experience more dramatic bleeding symptoms, heterozygotes may experience clinically significant bleeding following surgical procedures or trauma, and therefore the condition is not purely recessive. The clinical significance of FXI deficiency is complicated in that FXI levels do not correlate well with bleeding severity, and in fact the bleeding risk is variable even for an individual in response to different haemostatic challenges. We present the case of a 74-year-old man of Ashkenazi Jewish heritage with a family and personal history of bleeding during surgical procedures, who presented with excessive bleeding following total thyroidectomy. He was found to have a FXI level of 52% (low normal). Genetic testing revealed that he was heterozygous for the c.403G>T mutation. This case demonstrates successful work-up and perioperative management of a patient with FXI deficiency. PMID- 29467124 TI - Gastric and duodenal ischaemia after transarterial chemoembolisation for hepatocellular carcinoma: an unexpected but significant complication. AB - Transarterial chemoembolisation (TACE) is commonly used for unresectable intermediate-stage hepatocellular carcinoma (HCC). TACE is usually well tolerated. We report a case of a patient who presented with a gastrointestinal bleed from TACE. A 64-year-old man presented with chronic hepatitis C cirrhosis and multifocal bilobar HCC. He had previously undergone multiple TACE sessions, radiofrequency ablation and stereotactic body radiation therapy. In the evening of his TACE procedure, he developed abdominal pain and haematemesis. An oesophagogastroduodenoscopy (OGD) showed non-bleeding oesophageal varices and ulcerations in the stomach and duodenum, with pathology demonstrating mucosal necrosis. The patient recovered and was discharged on omeprazole. While TACE is considered safe with most patients only experiencing postembolisation syndrome, vascular complications have been reported. In our patient, OGD revealed ulcerations, with biopsies confirming ischaemic ulceration. The likely aetiology was seepage of the embolic particles into neighbouring arteries. Patients should be carefully selected for TACE and monitored post procedure. PMID- 29467125 TI - Cefepime-induced encephalopathy. PMID- 29467126 TI - Misunderstanding the goals of animal research. PMID- 29467127 TI - Quantitative Analysis of Immune Infiltrates in Primary Melanoma. AB - Novel methods to analyze the tumor microenvironment (TME) are urgently needed to stratify melanoma patients for adjuvant immunotherapy. Tumor-infiltrating lymphocyte (TIL) analysis, by conventional pathologic methods, is predictive but is insufficiently precise for clinical application. Quantitative multiplex immunofluorescence (qmIF) allows for evaluation of the TME using multiparameter phenotyping, tissue segmentation, and quantitative spatial analysis (qSA). Given that CD3+CD8+ cytotoxic lymphocytes (CTLs) promote antitumor immunity, whereas CD68+ macrophages impair immunity, we hypothesized that quantification and spatial analysis of macrophages and CTLs would correlate with clinical outcome. We applied qmIF to 104 primary stage II to III melanoma tumors and found that CTLs were closer in proximity to activated (CD68+HLA-DR+) macrophages than nonactivated (CD68+HLA-DR-) macrophages (P < 0.0001). CTLs were further in proximity from proliferating SOX10+ melanoma cells than nonproliferating ones (P < 0.0001). In 64 patients with known cause of death, we found that high CTL and low macrophage density in the stroma (P = 0.0038 and P = 0.0006, respectively) correlated with disease-specific survival (DSS), but the correlation was less significant for CTL and macrophage density in the tumor (P = 0.0147 and P = 0.0426, respectively). DSS correlation was strongest for stromal HLA-DR+ CTLs (P = 0.0005). CTL distance to HLA-DR- macrophages associated with poor DSS (P = 0.0016), whereas distance to Ki67- tumor cells associated inversely with DSS (P = 0.0006). A low CTL/macrophage ratio in the stroma conferred a hazard ratio (HR) of 3.719 for death from melanoma and correlated with shortened overall survival (OS) in the complete 104 patient cohort by Cox analysis (P = 0.009) and merits further development as a biomarker for clinical application.

PMID- 29467128 TI - Macrophages and CD8+ T Cells Mediate the Antitumor Efficacy of Combined CD40 Ligation and Imatinib Therapy in Gastrointestinal Stromal Tumors. AB - Tyrosine kinase inhibition of gastrointestinal stromal tumors (GIST) is effective but typically culminates in resistance and is rarely curative. Immunotherapy has potential application to GIST, as we previously showed that T-cell checkpoint blockade increases the antitumor effects of imatinib. Here, we showed that ligation of CD40 using an agonistic antibody (anti-CD40) activated tumor associated macrophages (TAMs) in vivo in a knock-in mouse model of GIST harboring a germline mutation in Kit exon 11. Activated TAMs had greater TNFalpha production and NFkappaB signaling and directly inhibited tumor cells in vitro Anti-CD40 required concomitant therapy with imatinib for efficacy and depended on TAMs, and to a lesser extent CD8+ T cells, but not on CD4+ T cells or B cells. In an analysis of 50 human GIST specimens by flow cytometry, we found that CD40 was expressed on human TAMs and tumor cells yet was downregulated after response to imatinib. CD40 ligation did not have a direct inhibitory effect on human GIST cells. Our findings provide the rationale for combining anti-CD40 and tyrosine kinase inhibition to treat human GIST.

AB - PURPOSE: Little information is available on patients on antiretroviral treatment (ART) after a long-term period from sub-Saharan Africa, with the longest follow up and related outcomes being after 10 years on ART. At the Infectious Diseases Institute (IDI) (Kampala, Uganda), we set up a cohort of patients already on ART for 10 years at the time of enrolment, who will be followed up for additional 10 years. PARTICIPANTS: A prospective observational cohort of 1000 adult patients previously on ART for 10 years was enrolled between May 2014 and September 2015. Patients were eligible for enrolment if they were in their consecutive 10th year of ART regardless of the combination of drugs for both first- and second-line ART. Data were collected at enrolment and all annual study visits. Follow-up visits are scheduled once a year for 10 years. Biological samples (packed cells, plasma and serum) are stored at enrolment and follow-up visits. FINDINGS TO DATE: Out of 1000 patients enrolled, 345 (34.5%) originate from a pre-existing research cohort at IDI, while 655 (65.5%) were enrolled from the routine clinic. Overall, 81% of the patients were on first line at the time of the enrolment in the ART long-term cohort, with the more frequent regimen being zidovudine plus lamivudine plus nevirapine (44% of the cohort), followed by zidovudine plus lamivudine plus efavirenz (22%) and tenofovir plus lamivudine or emtricitabine plus efavirenz (10%). At cohort enrolment, viral suppression was defined as HIV-RNA <400 copies/mL was 95.8%. FUTURE PLANS: Through collaboration with other institutions, we are planning several substudies, including the evaluation of the risk for cardiovascular diseases, the assessment of bone mineral density, screening for liver cirrhosis using fibroscan technology and investigation of drug-drug interactions between ART and common drugs used for non-communicable diseases. PMID- 29467130 TI - How do time trends in inhospital mortality compare? A retrospective study of England and Scotland over 17 years using administrative data. AB - OBJECTIVES: To examine the trends in inhospital mortality for England and Scotland over a 17-year period to determine whether and if so to what extent the time trends differ after controlling for differences in the patients treated. DESIGN: Analysis of retrospective administrative hospital data using descriptive aggregate statistics of trends in inhospital mortality and estimates of a logistic regression model of individual patient-level inhospital mortality accounting for patient characteristics, case-mix, and country-specific and year specific intercepts. SETTING: Secondary care across all hospitals in England and Scotland from 1997 to 2013. POPULATION: Over 190 million inpatient admissions, either electively or emergency, in England or Scotland from 1997 to 2013. DATA: Hospital Episode Statistics for England and the Scottish Morbidity Record 01 for Scotland. MAIN OUTCOME MEASURES: Separately for two admission pathways (elective and emergency), we examine aggregate time trends of the proportion of patients who die in hospital and a binary variable indicating whether an individual patient died in hospital or survived, and how that indicator is influenced by the patient's characteristics, the year and the country (England or Scotland) in which they were admitted. RESULTS: Inhospital mortality has declined in both countries over the period studied, for both elective and emergency admissions, but has declined more in England than Scotland. The difference in trend reduction is greater for elective admissions. These differences persist after controlling for patient characteristics and case-mix. CONCLUSIONS: Comparing data at country level suggests questions about the roles performed by or functioning of their healthcare systems. We found substantial differences between Scotland and England in regard to the trend reductions in inhospital mortality. Hospital resources are therefore being deployed increasingly differently over time in these two countries for reasons that have yet to be explained. PMID- 29467131 TI - HIV/AIDS mortality attributable to alcohol use in South Africa: a comparative risk assessment by socioeconomic status. AB - OBJECTIVES: To quantify HIV/AIDS mortality attributable to alcohol use in the adult general population of South Africa in 2012 by socioeconomic status (SES). DESIGN: Comparative risk assessment based on secondary individual data, aggregate data and risk relations reported in the literature. SETTING: South African adult general population. PARTICIPANTS: For metrics of alcohol use by SES, sex and age: 27 070 adults that participated in a nationally representative survey in 2012. For HRs of dying from HIV/AIDS by SES: 87 029 adults that participated in a cohort study (years 2000 to 2014) based out of the Umkhanyakude district, KwaZulu Natal. MAIN OUTCOME MEASURES: Alcohol-attributable fractions for HIV/AIDS mortality by SES, age and sex were calculated based on the risk of engaging in condom-unprotected sex under the influence of alcohol and interactions between SES and alcohol use. Age-standardised HIV/AIDS mortality rates attributable to alcohol by SES and sex were estimated using alcohol-attributable fractions and SES-specific and sex-specific death counts. Rate ratios were calculated comparing age-standardised rates in low versus high SES by sex. RESULTS: The age standardised HIV/AIDS mortality rate attributable to alcohol was 31.0 (95% uncertainty interval (UI) 21.6 to 41.3) and 229.6 (95% UI 108.8 to 351.6) deaths per 100 000 adults for men of high and low SES, respectively. For women the respective rates were 10.8 (95% UI 5.5 to 16.1) and 75.5 (95% UI 31.2 to 144.9). The rate ratio was 7.4 (95% UI 3.4 to 13.2) for men and 7.0 (95% UI 2.8 to 18.2) for women. Sensitivity analyses corroborated marked differences in alcohol attributable HIV/AIDS mortality, with rate ratios between 2.7 (95% UI 0.8 to 7.6; women) and 15.1 (95% UI 6.8 to 27.7; men). CONCLUSIONS: The present study showed that alcohol use contributed considerably to the socioeconomic differences in HIV/AIDS mortality. Targeting HIV infection under the influence of alcohol is a promising strategy for interventions to reduce the HIV/AIDS burden and related socioeconomic differences in South Africa.

METHODS: Five electronic databases were searched (PubMed, EMBASE, CRD, Cochrane Library and LILACS) to March 2016 for diagnostic accuracy studies of ICS test and standard reference tests for syphilis in pregnant women. Methodological quality was assessed using QUADAS-2 (Quality Assessment of Diagnostic Accuracy Studies). A bivariate meta-analysis was undertaken to generate pooled estimates of diagnostic parameters. Results were presented using a coupled forest plot of sensitivity and specificity and a scatter plot. RESULTS: The methodological quality of the five included studies with regards to risk of bias and applicability concern judgements was either low or unclear. One study was judged as high risk of bias for patient selection due to exclusion of pregnant women with a previous history of syphilis, and one study was judged at high risk of bias for study flow and timing as not all patients were included in the analysis. Five studies contributed to the meta-analysis, providing a pooled sensitivity and specificity for ICS of 0.85 (95% CrI: 0.73 to 0.92) and 0.98 (95% CrI: 0.95 to 0.99), respectively. CONCLUSIONS: This review and meta-analysis observed that rapid ICS POC tests have a high sensitivity and specificity when performed in pregnant women at antenatal clinics. However, the methodological quality of the existing evidence base should be taken into consideration when interpreting these results. PROSPERO REGISTRATION NUMBER: CRD42016036335. PMID- 29467133 TI - Time-dependent risks of cancer clustering among couples: a nationwide population based cohort study in Taiwan. AB - OBJECTIVES: Spousal clustering of cancer warrants attention. Whether the common environment or high-age vulnerability determines cancer clustering is unclear. The risk of clustering in couples versus non-couples is undetermined. The time to cancer clustering after the first cancer diagnosis is yet to be reported. This study investigated cancer clustering over time among couples by using nationwide data. METHODS: A cohort of 5643 married couples in the 2002-2013 Taiwan National Health Insurance Research Database was identified and randomly matched with 5643 non-couple pairs through dual propensity score matching. Factors associated with clustering (both spouses with tumours) were analysed by using the Cox proportional hazard model. RESULTS: Propensity-matched analysis revealed that the risk of clustering of all tumours among couples (13.70%) was significantly higher than that among non-couples (11.84%) (OR=1.182, 95% CI 1.058 to 1.321, P=0.0031). The median time to clustering of all tumours and of malignant tumours was 2.92 and 2.32 years, respectively. Risk characteristics associated with clustering included high age and comorbidity. CONCLUSIONS: Shared environmental factors among spouses might be linked to a high incidence of cancer clustering. Cancer incidence in one spouse may signal cancer vulnerability in the other spouse. Promoting family-oriented cancer care in vulnerable families and preventing shared lifestyle risk factors for cancer are suggested. PMID- 29467134 TI - NHS Diabetes Prevention Programme in England: formative evaluation of the programme in early phase implementation. AB - OBJECTIVES: Evaluation of the demonstrator phase and first wave roll-out of the National Health Service (NHS) Diabetes Prevention Programme (DPP) in England. To examine: (1) intervention design, provision and fidelity assessment procedures; (2) risk assessment and recruitment pathways and (3) data collection for monitoring and evaluation. To provide recommendations informing decision makers on programme quality, improvements and future evaluation. DESIGN: We reviewed programme documents, mapping against the NHS DPP specification and National Institute for Health and Care Excellence (NICE) public health guideline: Type 2 diabetes (T2D) prevention in people at high risk (PH38), conducted qualitative research using individual interviews and focus group discussions with stakeholders and examined recruitment, fidelity and data collection procedures. SETTING: Seven NHS DPP demonstrator sites and, subsequently, 27 first wave areas across England. INTERVENTIONS: Intensive behavioural intervention with weight loss, diet and physical activity goals. The national programme specifies at least 13 sessions over 9 months, delivered face to face to groups of 15-20 adults with non-diabetic hyperglycaemia, mainly recruited from primary care and NHS Health Checks. PARTICIPANTS: Participants for qualitative research were purposively sampled to provide a spread of stakeholder experience. Documents for review were provided via the NHS DPP Management Group. FINDINGS: The NHS DPP specification reflected current evidence with a clear framework for service provision. Providers, with national capacity to deliver, supplied intervention plans compliant with this framework. Stakeholders highlighted limitations in fidelity assessment and recruitment and retention challenges, especially in reach and equity, that could adversely impact on implementation. Risk assessment for first wave eligibility differed from NICE guidance. CONCLUSIONS: The NHS DPP provides an evidence-based behavioural intervention for prevention of T2D in adults at high risk, with capacity to deliver nationally. Framework specification allows for balance between consistency and contextual variation in intervention delivery, with session details devolved to providers. Limitations in fidelity assurance, data collection procedures and recruitment issues could adversely impact on intervention effectiveness and restrict evaluation. PMID- 29467135 TI - Physiological responses to arm versus leg activity in patients with chronic obstructive pulmonary disease: a systematic review protocol. AB - INTRODUCTION: Compared with healthy older adults, people with chronic obstructive pulmonary disease (COPD) have reduced capacity and increased symptoms during leg and arm activities. While the mechanisms underlying limitations and symptoms during leg activities have been investigated in detail, limitations and symptoms during arm activities are not well understood, and the potential differences between physiological responses of leg and arm activities have not been systematically synthesised. Determining physiological responses and symptoms of arm activities compared with physiological responses and symptoms of leg activities will help us understand the mechanisms behind the difficulties that people with COPD experience when performing physical activities, and determine how exercise training should be prescribed. Thus, the aim of this systematic review is to compare the physiological responses and symptoms during activities involving the arms relative to activities involving the legs in people diagnosed with COPD. METHODS AND ANALYSES: This protocol is reported in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols. Potentially relevant studies will be identified from CINAHL, EMBASE, PEDro, Cochrane Central Register of Controlled Trials and PubMed databases. The Population, Exposure, Comparator, Outcomes, and Study characteristics framework will be used to systematise the process of selecting and extracting data from relevant studies. Assessment of the methodological quality of the studies will be done by using the 14 most relevant components from the checklist by Downs and Black. The result will be presented with a narrative synthesis, and if appropriate with meta-analyses. ETHICS AND DISSEMINATION: Ethical approval is not required as this study is a systematic review. It is our intention to submit the results of our review for peer-reviewed publication. PROSPERO REGISTRATION NUMBER: CRD42017074476. PMID- 29467137 TI - Health state utility values among children and adolescents with disabilities: protocol for a systematic review. AB - INTRODUCTION: Increasingly, assessment of healthcare technologies and interventions requires the assessment of both costs and utilities. Health state utility values (HSUVs) are measured using a range of generic and condition specific measures. While reviews have identified that generic measures of HSUVs may lack validity in adults with conditions that result in physical disability, there is little information available on the methods used to obtain HSUVs in children and adolescents with disabilities. The objectives of this systematic review are to describe the methods used to obtain HSUVs, including mode of administration and psychometric properties, and provide summary statistics for HSUVs among children and adolescents with disabilities. METHODS AND ANALYSIS: The following databases will be searched from inception for English-language studies of any design: PubMed, PsychInfo, Medline, Scopus, CINAHL Plus, Econlit and EMBASE databases. Two reviewers will independently screen titles, abstracts and full text articles for studies reporting HSUVs and/or data on the psychometric properties of preference-based measures for children and adolescents with disabilities aged up to 19 years. Two reviewers will independently extract data items including descriptors of the study methods and sample, instruments used to capture HSUVs, summary statistics for HSUVs and items relating to the quality of reporting. A descriptive summary of results from included studies and summary statistics for HSUVs will be presented. If sufficient data is identified, we will pool summary statistics for HSUVs according to the method used to obtain the HSUV using a random effects model. In addition, we will explore the determinants of the HSUVs using a meta-regression. ETHICS AND DISSEMINATION: Ethical approval will not be required as no original data will be collected as part of this review. The completed review will be submitted for publication in a peer-reviewed journal and presentation at conferences. PROSPERO REGISTRATION NUMBER: CRD42018086574. PMID- 29467136 TI - Attitudes and perceptions of health professionals towards management of hypothyroidism in general practice: a qualitative interview study. AB - OBJECTIVE: To explore the attitudes and perceptions of health professionals towards management of hypothyroidism that contributes to the suboptimal treatment of hypothyroidism in general practice. DESIGN: A qualitative interview study using semistructured interviews. PARTICIPANTS: Sixteen participants were interviewed between March and August 2016 comprising nine general practitioners (GPs), four pharmacists, two practice nurses and one nurse practitioner. SETTING: General practice and community pharmacies in the counties of Northumberland, Tyne and Wear, Stockton-on-Tees and North Cumbria, North of England, UK. METHOD: A grounded-theory approach was used to generate themes from interviews, which were underpinned by the theory of planned behaviour to give explanation to the data. RESULTS: Although health professionals felt that hypothyroidism was easy to manage, GPs and nurses generally revealed inadequate knowledge of medication interactions and levothyroxine pharmacokinetics. Pharmacists felt limited in the advice that they provide to patients due to lack of access to patient records. Most GPs and nurses followed local guidelines, and relied on blood tests over clinical symptoms to adjust levothyroxine dose. The information exchanged between professional and patient was usually restricted by time and often centred on symptoms rather than patient education. Health professionals felt that incorrect levothyroxine adherence was the main reason behind suboptimal treatment, although other factors such as comorbidity and concomitant medication were mentioned. Enablers perceived by health professionals to improve the management of hypothyroidism included continuity of care, blood test reminders, system alerts for interfering medications and prescription renewal, and accessible blood tests and levothyroxine prescriptions for patients. CONCLUSION: There is a significant health professional behavioural component to the management of hypothyroidism. Addressing the differences in patient and professional knowledge and perceptions could reduce the barriers to optimal treatment, while continuity of care and increased involvement of pharmacists and practice nurses would help to promote optimal thyroid replacement. PMID- 29467139 TI - SULFATION PATHWAYS: Formation and hydrolysis of sulfonated estrogens in the porcine testis and epididymis. AB - Boars exhibit high concentrations of sulfonated estrogens (SE) mainly originating from the testicular-epididymal compartment. Intriguingly, in porcine Leydig cells, sulfonation of estrogens is colocalized with aromatase and steroid sulfatase (STS), indicating that de novo synthesis of unconjugated estrogens (UE), their sulfonation and hydrolysis of SE occur within the same cell type. So far in boars no plausible concept concerning the role of SE has been put forward. To obtain new information on SE formation and hydrolysis, the porcine testicular epididymal compartment was screened for the expression of the estrogen-specific sulfotransferase SULT1E1 and STS applying real-time RT-qPCR, Western blot and immunohistochemistry. The epididymal head was identified as the major site of SULT1E1 expression, whereas in the testis, it was virtually undetectable. However, SE tissue concentrations are clearly consistent with the testis as the predominant site of estrogen sulfonation. Results from measurements of estrogen sulfotransferase activity indicate that in the epididymis, SULT1E1 is the relevant enzyme, whereas in the testis, estrogens are sulfonated by a different sulfotransferase with a considerably lower affinity. STS expression and activity was high in the testis (Leydig cells, rete testis epithelium) but also present throughout the epididymis. In the epididymis, SULT1E1 and STS were colocalized in the ductal epithelium, and there was evidence for their apocrine secretion into the ductal lumen. The results suggest that in porcine Leydig cells, SE may be produced as a reservoir to support the levels of bioactive UE via the sulfatase pathway during periods of low activity of the pulsatile testicular steroidogenesis.

AB - Evidence indicates that central regulation of food intake is well conserved along the vertebrate lineage, at least between teleost fish and mammals. However, several differences arise in the comparison between both groups. In this review, we describe similarities and differences between teleost fish and mammals on an evolutionary perspective. We focussed on the existing knowledge of specific fish features conditioning food intake, anatomical homologies and analogies between both groups as well as the main signalling pathways of neuroendocrine and metabolic nature involved in the homeostatic and hedonic central regulation of food intake. PMID- 29467138 TI - Pathways: patient-centred decision counselling for women at risk of cancer related infertility: a protocol for a comparative effectiveness cluster randomised trial. AB - INTRODUCTION: National guidelines recommend that all reproductive-age women with cancer be informed of their fertility risks and offered referral to fertility specialists to discuss fertility preservation options. However, reports indicate that only 5% of patients have consultations, and rates of long-term infertility related distress remain high. Previous studies report several barriers to fertility preservation; however, initial success has been reported using provider education, patient decision aids and navigation support. This protocol will test effects of a multicomponent intervention compared with usual care on women's fertility preservation knowledge and decision-making outcomes. METHODS AND ANALYSIS: This cluster-randomised trial will compare the multicomponent intervention (provider education, patient decision aid and navigation support) with usual care (consultation and referral, if requested). One hundred newly diagnosed English-speaking women of reproductive age who are at risk of cancer related infertility will be recruited from four regional oncology clinics.The Pathways patient decision aid website provides (1) up-to-date evidence and descriptions of fertility preservation and other family-building options, tailored to cancer type; (2) structured guidance to support personalising the information and informed decision-making; and (3) a printable summary to help women prepare for discussions with their oncologist and/or fertility specialist. Four sites will be randomly assigned to intervention or control groups. Participants will be recruited after their oncology consultation and asked to complete online questionnaires at baseline, 1 week and 2 months to assess their demographics, fertility preservation knowledge, and decision-making process and quality. The primary outcome (decisional conflict) will be tested using Fisher's exact test. Secondary outcomes will be assessed using generalised linear mixed models, and sensitivity analyses will be conducted, as appropriate. ETHICS AND DISSEMINATION: The University of Texas MD Anderson Cancer Center provided approval and ongoing review of this protocol. Results will be presented at relevant scientific meetings and submitted for publication in a peer-reviewed journal. TRIAL REGISTRATION NUMBER: NCT03141437; Pre-results. PMID- 29467141 TI - The role of Sirtuin1-PPARgamma axis in placental development and function. AB - Placental development is important for proper in utero growth and development of the fetus, as well as maternal well-being during pregnancy. Abnormal differentiation of placental epithelial cells, called trophoblast, is at the root of multiple pregnancy complications, including miscarriage, the maternal hypertensive disorder preeclampsia and intrauterine growth restriction. The ligand-activated nuclear receptor, PPARgamma, and nutrient sensor, Sirtuin-1, both play a role in numerous pathways important to cell survival and differentiation, metabolism and inflammation. However, each has also been identified as a key player in trophoblast differentiation and placental development. This review details these studies, and also describes how various stressors, including hypoxia and inflammation, alter the expression or activity of PPARgamma and Sirtuin-1, thereby contributing to placenta-based pregnancy complications.

AB - In 1988, Carlos Dotti, Chris Sullivan, and I published a paper on the establishment of polarity by hippocampal neurons in culture, which continues to be frequently cited 30 years later (Dotti et al., 1988). By following individual neurons from the time of plating until they had formed well developed axonal and dendritic arbors, we identified the five stages of development that lead to the mature expression of neuronal polarity. We were surprised to find that, before axon formation, the cells pass through a multipolar phase, in which several, apparently identical short neurites undergo periods of extension and retraction. Then one of these neurites begins a period of prolonged growth, becoming the definitive axon; the remaining neurites subsequently become dendrites. This observation suggested that any of the initial neurites were capable of becoming axons, a hypothesis confirmed by later work. In this Progressions article, I will try to recall the circumstances that led to this work, recapture some of the challenges we faced in conducting these experiments, and consider why some of today's neuroscientists still find this paper relevant. PMID- 29467147 TI - Alectinib for advanced ALK-positive non-small-cell lung cancer. AB - PURPOSE: The pharmacology, pharmacokinetics, clinical efficacy, safety and tolerability, dosage and administration, and place in therapy of alectinib for treatment of patients with non-small-cell lung cancer (NSCLC) are reviewed. SUMMARY: In patients with NSCLC driven by mutations of ALK, the gene coding for anaplastic lymphoma kinase (ALK), treatment with the ALK inhibitor crizotinib has been found to provide median progression-free survival (PFS) of 10.9 months; however, therapeutic failures and tumor progression to brain metastases are common with crizotinib use, prompting research to find more potent and tolerable ALK inhibitors that target major oncogenic drivers of NSCLC. Alectinib is a next generation ALK inhibitor initially approved by the Food and Drug Administration for use in patients with metastatic ALK-positive NSCLC who are intolerant of or have disease progression during crizotinib therapy. In clinical trials, alectinib was found effective for delaying disease progression and, more importantly, reducing brain metastases in patients with NSCLC who developed resistance or intolerance to previous crizotinib therapy. Published data from clinical trials indicate that the most common grade 1 and 2 adverse effects associated with alectinib use are fatigue, constipation, peripheral edema, and myalgia; the most common grade 3 or 4 reactions include increases in creatine phosphokinase, alanine aminotransferase, and aspartate aminotransferase levels. CONCLUSION: Alectinib appears to be effective and safe for use in patients with metastatic ALK-positive NSCLC, with demonstrated superiority over crizotinib in terms of PFS rates. Research to better define ALK inhibitor resistance mechanisms and alectinib's place in therapy is ongoing. PMID- 29467145 TI - Electrophysiological Signatures of Spatial Boundaries in the Human Subiculum. AB - Environmental boundaries play a crucial role in spatial navigation and memory across a wide range of distantly related species. In rodents, boundary representations have been identified at the single-cell level in the subiculum and entorhinal cortex of the hippocampal formation. Although studies of hippocampal function and spatial behavior suggest that similar representations might exist in humans, boundary-related neural activity has not been identified electrophysiologically in humans until now. To address this gap in the literature, we analyzed intracranial recordings from the hippocampal formation of surgical epilepsy patients (of both sexes) while they performed a virtual spatial navigation task and compared the power in three frequency bands (1-4, 4-10, and 30-90 Hz) for target locations near and far from the environmental boundaries. Our results suggest that encoding locations near boundaries elicited stronger theta oscillations than for target locations near the center of the environment and that this difference cannot be explained by variables such as trial length, speed, movement, or performance. These findings provide direct evidence of boundary-dependent neural activity localized in humans to the subiculum, the homolog of the hippocampal subregion in which most boundary cells are found in rodents, and indicate that this system can represent attended locations that rather than the position of one's own body.SIGNIFICANCE STATEMENT Spatial computations using environmental boundaries are an integral part of the brain's spatial mapping system. In rodents, border/boundary cells in the subiculum and entorhinal cortex reveal boundary coding at the single-neuron level. Although there is good reason to believe that such representations also exist in humans, the evidence has thus far been limited to functional neuroimaging studies that broadly implicate the hippocampus in boundary-based navigation. By combining intracranial recordings with high-resolution imaging of hippocampal subregions, we identified a neural marker of boundary representation in the human subiculum. PMID- 29467148 TI - Controlling postoperative use of i.v. acetaminophen at an academic medical center. AB - PURPOSE: Results of an interprofessional formulary initiative to decrease postoperative prescribing of i.v. acetaminophen are reported. SUMMARY: After a medical center added i.v. acetaminophen to its formulary, increased prescribing of the i.v. formulation and a 3-fold price increase resulted in monthly spending of more than $40,000, prompting an organizationwide effort to curtail that cost while maintaining effective pain management. The surgery, anesthesia, and pharmacy departments applied the Institute for Healthcare Improvement's Model for Improvement to implement (1) pharmacist-led enforcement of prescribing restrictions, (2) retrospective evaluation of i.v. acetaminophen's impact on rates of opioid-related adverse effects, (3) restriction of prescribing of the drug to 1 postoperative dose on select patient care services, and (4) guideline driven pain management according to an enhanced recovery after surgery (ERAS) protocol. Monitored metrics included the monthly i.v. acetaminophen prescribing rate, the proportion of i.v. acetaminophen orders requiring pharmacist intervention to enforce prescribing restrictions, and prescribing rates for select adjunctive analgesics. Within a year of project implementation, the mean monthly i.v. acetaminophen prescribing rate decreased by 83% from baseline to about 6 doses per 100 patient-days, with a decline in the monthly drug cost to about $4,000. Documented pharmacist interventions increased 2.7-fold, and use of oral acetaminophen, ketorolac, and gabapentin in ERAS areas increased by 18% overall. CONCLUSION: An interprofessional initiative at a large medical center reduced postoperative use of i.v. acetaminophen by more than 80% and yielded over $400,000 in annual cost savings.

AB - BACKGROUND: The associations between high-sensitivity troponin I (hsTnI) levels and coronary artery disease (CAD) severity and progression remain unclear. We investigated whether there is an association between hsTnI and angiographic severity and progression of CAD and whether the predictive value of hsTnI level for incident cardiovascular outcomes is independent of CAD severity. METHODS AND RESULTS: In 3087 patients (aged 63+/-12 years, 64% men) undergoing cardiac catheterization without evidence of acute myocardial infarction, the severity of CAD was calculated by the number of major coronary arteries with >=50% stenosis and the Gensini score. CAD progression was assessed in a subset of 717 patients who had undergone >=2 coronary angiograms >3 months before enrollment. Patients were followed up for incident all-cause mortality and incident cardiovascular events. Of the total population, 11% had normal angiograms, 23% had nonobstructive CAD, 20% had 1-vessel CAD, 20% had 2-vessel CAD, and 26% had 3 vessel CAD. After adjusting for age, sex, race, body mass index, smoking, hypertension, diabetes mellitus history, and renal function, hsTnI levels were independently associated with the severity of CAD measured by the Gensini score (log 2 beta=0.31; 95% confidence interval, 0.18-0.44; P<0.001) and with CAD progression (log 2 beta=0.36; 95% confidence interval, 0.14-0.58; P=0.001). hsTnI level was also a significant predictor of incident death, cardiovascular death, myocardial infarction, revascularization, and cardiac hospitalizations, independent of the aforementioned covariates and CAD severity. CONCLUSIONS: Higher hsTnI levels are associated with the underlying burden of coronary atherosclerosis, more rapid progression of CAD, and higher risk of all-cause mortality and incident cardiovascular events. Whether more aggressive treatment aimed at reducing hsTnI levels can modulate disease progression requires further investigation.

AB - OBJECTIVE: To evaluate differences in downstream testing, coronary revascularisation, and clinical outcomes following non-invasive diagnostic modalities used to detect coronary artery disease. DESIGN: Systematic review and network meta-analysis. DATA SOURCES: Medline, Medline in process, Embase, Cochrane Library for clinical trials, PubMed, Web of Science, SCOPUS, WHO International Clinical Trials Registry Platform, and Clinicaltrials.gov. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Diagnostic randomised controlled trials comparing non-invasive diagnostic modalities in patients presenting with symptoms suggestive of low risk acute coronary syndrome or stable coronary artery disease. DATA SYNTHESIS: A random effects network meta-analysis synthesised available evidence from trials evaluating the effect of non-invasive diagnostic modalities on downstream testing and patient oriented outcomes in patients with suspected coronary artery disease. Modalities included exercise electrocardiograms, stress echocardiography, single photon emission computed tomography-myocardial perfusion imaging, real time myocardial contrast echocardiography, coronary computed tomographic angiography, and cardiovascular magnetic resonance. Unpublished outcome data were obtained from 11 trials. RESULTS: 18 trials of patients with low risk acute coronary syndrome (n=11 329) and 12 trials of those with suspected stable coronary artery disease (n=22 062) were included. Among patients with low risk acute coronary syndrome, stress echocardiography, cardiovascular magnetic resonance, and exercise electrocardiograms resulted in fewer invasive referrals for coronary angiography than coronary computed tomographic angiography (odds ratio 0.28 (95% confidence interval 0.14 to 0.57), 0.32 (0.15 to 0.71), and 0.53 (0.28 to 1.00), respectively). There was no effect on the subsequent risk of myocardial infarction, but estimates were imprecise. Heterogeneity and inconsistency were low. In patients with suspected stable coronary artery disease, an initial diagnostic strategy of stress echocardiography or single photon emission computed tomography-myocardial perfusion imaging resulted in fewer downstream tests than coronary computed tomographic angiography (0.24 (0.08 to 0.74) and 0.57 (0.37 to 0.87), respectively). However, exercise electrocardiograms yielded the highest downstream testing rate. Estimates for death and myocardial infarction were imprecise without clear discrimination between strategies. CONCLUSIONS: For patients with low risk acute coronary syndrome, an initial diagnostic strategy of stress echocardiography or cardiovascular magnetic resonance is associated with fewer referrals for invasive coronary angiography and revascularisation procedures than non-invasive anatomical testing, without apparent impact on the future risk of myocardial infarction. For suspected stable coronary artery disease, there was no clear discrimination between diagnostic strategies regarding the subsequent need for invasive coronary angiography, and differences in the risk of myocardial infarction cannot be ruled out.

PMID- 29467163 TI - Stac proteins associate with the critical domain for excitation-contraction coupling in the II-III loop of CaV1.1. AB - In skeletal muscle, residues 720-764/5 within the CaV1.1 II-III loop form a critical domain that plays an essential role in transmitting the excitation contraction (EC) coupling Ca2+ release signal to the type 1 ryanodine receptor (RyR1) in the sarcoplasmic reticulum. However, the identities of proteins that interact with the loop and its critical domain and the mechanism by which the II III loop regulates RyR1 gating remain unknown. Recent work has shown that EC coupling in skeletal muscle of fish and mice depends on the presence of Stac3, an adaptor protein that is highly expressed only in skeletal muscle. Here, by using colocalization as an indicator of molecular interactions, we show that Stac3, as well as Stac1 and Stac2 (predominantly neuronal Stac isoforms), interact with the II-III loop of CaV1.1. Further, we find that these Stac proteins promote the functional expression of CaV1.1 in tsA201 cells and support EC coupling in Stac3 null myotubes and that Stac3 is the most effective. Coexpression in tsA201 cells reveals that Stac3 interacts only with II-III loop constructs containing the majority of the CaV1.1 critical domain residues. By coexpressing Stac3 in dysgenic (CaV1.1-null) myotubes together with CaV1 constructs whose chimeric II III loops had previously been tested for functionality, we reveal that the ability of Stac3 to interact with them parallels the ability of these constructs to mediate skeletal type EC coupling. Based on coexpression in tsA201 cells, the interaction of Stac3 with the II-III loop critical domain does not require the presence of the PKC C1 domain in Stac3, but it does require the first of the two SH3 domains. Collectively, our results indicate that activation of RyR1 Ca2+ release by CaV1.1 depends on Stac3 being bound to critical domain residues in the II-III loop. PMID- 29467164 TI - The discovery of the ability of rod photoreceptors to signal single photons. AB - Vertebrate rod photoreceptors evolved the astonishing ability to respond reliably to single photons. In parallel, the proximate neurons of the visual system evolved the ability to reliably encode information from a few single-photon responses (SPRs) as arising from the presence of an object of interest in the visual environment. These amazing capabilities were first inferred from measurements of human visual threshold by Hecht et al. (1942), whose paper has since been cited over 1,000 times. Subsequent research, in part inspired by Hecht et al.'s discovery, has directly measured rod SPRs, characterized the molecular mechanism responsible for their generation, and uncovered much about the specializations in the retina that enable the reliable transmission of SPRs in the teeth of intrinsic neuronal noise.

PMID- 29467166 TI - Polarised epithelial monolayers of the gastric mucosa reveal insights into mucosal homeostasis and defence against infection. AB - OBJECTIVE: Helicobacter pylori causes life-long colonisation of the gastric mucosa, leading to chronic inflammation with increased risk of gastric cancer. Research on the pathogenesis of this infection would strongly benefit from an authentic human in vitro model. DESIGN: Antrum-derived gastric glands from surgery specimens served to establish polarised epithelial monolayers via a transient air-liquid interface culture stage to study cross-talk with H. pylori and the adjacent stroma. RESULTS: The resulting 'mucosoid cultures', so named because they recapitulate key characteristics of the gastric mucosa, represent normal stem cell-driven cultures that can be passaged for months. These highly polarised columnar epithelial layers encompass the various gastric antral cell types and secrete mucus at the apical surface. By default, they differentiate towards a foveolar, MUC5AC-producing phenotype, whereas Wnt signalling stimulates proliferation of MUC6-producing cells and preserves stemness-reminiscent of the gland base. Stromal cells from the lamina propria secrete Wnt inhibitors, antagonising stem-cell niche signalling and inducing differentiation. On infection with H. pylori, a strong inflammatory response is induced preferentially in the undifferentiated basal cell phenotype. Infection of cultures for several weeks produces foci of viable bacteria and a persistent inflammatory condition, while the secreted mucus establishes a barrier that only few bacteria manage to overcome. CONCLUSION: Gastric mucosoid cultures faithfully reproduce the features of normal human gastric epithelium, enabling new approaches for investigating the interaction of H. pylori with the epithelial surface and the cross-talk with the basolateral stromal compartment. Our observations provide striking insights in the regulatory circuits of inflammation and defence. PMID- 29467167 TI - Can Family Planning Service Statistics Be Used to Track Population-Level Outcomes? AB - The need for annual family planning program tracking data under the Family Planning 2020 (FP2020) initiative has contributed to renewed interest in family planning service statistics as a potential data source for annual estimates of the modern contraceptive prevalence rate (mCPR). We sought to assess (1) how well a set of commonly recorded data elements in routine service statistics systems could, with some fairly simple adjustments, track key population-level outcome indicators, and (2) whether some data elements performed better than others. We used data from 22 countries in Africa and Asia to analyze 3 data elements collected from service statistics: (1) number of contraceptive commodities distributed to clients, (2) number of family planning service visits, and (3) number of current contraceptive users. Data quality was assessed via analysis of mean square errors, using the United Nations Population Division World Contraceptive Use annual mCPR estimates as the "gold standard." We also examined the magnitude of several components of measurement error: (1) variance, (2) level bias, and (3) slope (or trend) bias. Our results indicate modest levels of tracking error for data on commodities to clients (7%) and service visits (10%), and somewhat higher error rates for data on current users (19%). Variance and slope bias were relatively small for all data elements. Level bias was by far the largest contributor to tracking error. Paired comparisons of data elements in countries that collected at least 2 of the 3 data elements indicated a modest advantage of data on commodities to clients. None of the data elements considered was sufficiently accurate to be used to produce reliable stand-alone annual estimates of mCPR. However, the relatively low levels of variance and slope bias indicate that trends calculated from these 3 data elements can be productively used in conjunction with the Family Planning Estimation Tool (FPET) currently used to produce annual mCPR tracking estimates for FP2020.

AB - Dermatophytes include fungal species that infect humans, as well as those that also infect other animals or only grow in the environment. The dermatophyte species Trichophyton rubrum is a frequent cause of skin infection in immunocompetent individuals. While members of the T. rubrum species complex have been further categorized based on various morphologies, their population structure and ability to undergo sexual reproduction are not well understood. In this study, we analyze a large set of T. rubrum and T. interdigitale isolates to examine mating types, evidence of mating, and genetic variation. We find that nearly all isolates of T. rubrum are of a single mating type, and that incubation with T. rubrum "morphotype" megninii isolates of the other mating type failed to induce sexual development. While the region around the mating type locus is characterized by a higher frequency of SNPs compared to other genomic regions, we find that the population is remarkably clonal, with highly conserved gene content, low levels of variation, and little evidence of recombination. These results support a model of recent transition to asexual growth when this species specialized to growth on human hosts. PMID- 29467169 TI - Functional Redundancy of DICER Cofactors TARBP2 and PRKRA During Murine Embryogenesis Does Not Involve miRNA Biogenesis. AB - Several in vitro studies have suggested that canonical microRNA (miRNA) biogenesis requires the DICER cofactors TARBP2 and PRKRA for processing of pre miRNAs to mature miRNAs. To investigate the roles of TARBP2 and PRKRA in miRNA biogenesis in vivo, and to determine possible functional redundancy, we first compared the phenotypes of Tarbp2 and Prkra single and double mutants. In contrast to Dicer -/- embryos, which die by embryonic day 7.5 (E7.5), single Tarbp2 -/- and Prkra -/- mice survive beyond E7.5 and either die perinatally or survive and exhibit cranial/facial abnormalities, respectively. In contrast, only a few Tarbp2 -/- ; Prkra -/- double mutants survived beyond E12.5, suggesting genetic redundancy between Tarbp2 and Prkra during embryonic development. Sequencing of miRNAs from single-mutant embryos at E15.5 revealed changes in abundance and isomiR type in Tarbp2 -/- , but not Prkra -/- , embryos, demonstrating that TARBP2, but not PRKRA, functions in miRNA biogenesis of a subclass of miRNAs, and suggesting that functional redundancy between TARBP2 and PRKRA does not involve miRNA biogenesis.

AB - Ebstein's anomaly is a rare entity affecting around 1 in 200,000 live births and accounts for less than 1% of congenital heart diseases. Ebstein's anomaly with an associated right-sided myxoma is extremely rare, with only one other case report found in the literature. Previous reports have also noted cases of Ebstein's anomaly associated with left-sided myxomas. We describe a female patient with, to our knowledge, the first case of a histopathologically confirmed right ventricular myxoma in the setting of Ebstein's anomaly.

PMID- 29467172 TI - Amylin Selectively Signals Onto POMC Neurons in the Arcuate Nucleus of the Hypothalamus. AB - Amylin phosphorylates ERK (p-ERK) in the area postrema to reduce eating and synergizes with leptin to phosphorylate STAT3 in the arcuate (ARC) and ventromedial (VMN) hypothalamic nuclei to reduce food intake and body weight. The current studies assessed potential amylin and amylin-leptin ARC/VMN interactions on ERK signaling and their roles in postnatal hypothalamic pathway development. In amylin knockout mice, the density of agouti-related protein (AgRP) immunoreactive (IR) fibers in the hypothalamic paraventricular nucleus (PVN) was increased, while the density of alpha-melanocyte-stimulating hormone (alphaMSH) fibers was decreased. In mice deficient of the amylin receptor components RAMP1/3, both AgRP and alphaMSH-IR fiber densities were decreased, while only alphaMSH-IR fiber density was decreased in rats injected neonatally in the ARC/VMN with an adeno-associated virus short hairpin RNA against the amylin core receptor. Amylin induced p-ERK in ARC neurons, 60% of which was present in POMC expressing neurons, with none in NPY neurons. An amylin-leptin interaction was shown by an additive effect on ARC ERK signaling in neonatal rats and a 44% decrease in amylin-induced p-ERK in the ARC of leptin receptor-deficient and of ob/ob mice. Together, these results suggest that amylin directly acts, through a p-ERK-mediated process, on POMC neurons to enhance ARC-PVN alphaMSH pathway development. PMID- 29467173 TI - qSOFA, SIRS and NEWS for predicting inhospital mortality and ICU admission in emergency admissions treated as sepsis. AB - BACKGROUND: The third international consensus definition for sepsis recommended use of a new prognostic tool, the quick Sequential Organ Failure Assessment (qSOFA), based on its ability to predict inhospital mortality and prolonged intensive care unit (ICU) stay in patients with suspected infection. While several studies have compared the prognostic accuracy of qSOFA to the Systemic Inflammatory Response Syndrome (SIRS) criteria in suspected sepsis, few have compared qSOFA and SIRS to the widely used National Early Warning Score (NEWS). METHODS: This was a retrospective cohort study carried out in a UK tertiary centre. The study population comprised emergency admissions in whom sepsis was suspected and treated. The accuracy for predicting inhospital mortality and ICU admission was calculated and compared for qSOFA, SIRS and NEWS. RESULTS: Among 1818 patients, 53 were admitted to ICU (3%) and 265 died in hospital (15%). For predicting inhospital mortality, the area under the receiver operating characteristics curve for NEWS (0.65, 95% CI 0.61 to 0.68) was similar to qSOFA (0.62, 95% CI 0.59 to 0.66) (test for difference, P=0.18) and superior to SIRS (P<0.001), which was not predictive. The sensitivity of NEWS>=5 (74%, 95% CI 68% to 79%) was similar to SIRS>=2 (80%, 95% CI 74% to 84%) and higher than qSOFA>=2 (37%, 95% CI 31% to 43%). The specificity of NEWS>=5 (43%, 95% CI 41% to 46%) was higher than SIRS>=2 (21%, 95% CI 19% to 23%) and lower than qSOFA>=2 (79%, 95% CI 77% to 81%). The negative predictive value was 88% (86%-90%) for qSOFA, 86% (82% 89%) for SIRS and 91% (88%-93%) for NEWS. Results were similar for the secondary outcome of ICU admission. CONCLUSION: NEWS has equivalent or superior value for most test characteristics relative to SIRS and qSOFA, calling into question the rationale of adopting qSOFA in institutions where NEWS is already in use. PMID- 29467175 TI - Growth affects dispersal success in social mole-rats, but not the duration of philopatry. AB - In naked mole-rats (Heterocephalus glaber), some non-breeding males show faster growth and are more likely to disperse than others. These differences have been suggested to be the result of a specialized developmental strategy leading to shorter philopatry and independent breeding, as opposed to extended philopatry as non-reproductive helpers. However, it is unclear whether fast-growing males disperse sooner than slow-growing males. An alternative explanation is that variation in quality between individuals causes high-quality individuals to grow quickly and maximize dispersal success without reducing philopatry. Here we show that in Damaraland mole-rats (Fukomys damarensis), males that subsequently disperse successfully grow faster than other non-reproductive males. This pattern is predicted by both hypotheses and does not discriminate between them. However, contrary to the suggestion that faster growth represents a developmental specialization for early dispersal, fast-growing and slow-growing males remained equally long in their natal groups. Our study provides no evidence for adaptive divergence in male development leading either to early dispersal or extended philopatry. Instead of representing specialized dispersers, fast-growing males of this species may be high-quality individuals.

AB - Cancer has been characterized as a genetic disease, associated with mutations that cause pathological alterations of the cell cycle, adhesion, or invasive motility. Recently, the importance of the anomalous mechanical properties of tumor tissues, which activate tumorigenic biochemical pathways, has become apparent. This mechanical induction in tumors appears to consist of the destabilization of adult tissue homeostasis as a result of the reactivation of embryonic developmental mechanosensitive pathways in response to pathological mechanical strains. These strains occur in many forms, for example, hypervascularization in late tumors leads to high static hydrodynamic pressure that can promote malignant progression through hypoxia or anomalous interstitial liquid and blood flow. The high stiffness of tumors directly induces the mechanical activation of biochemical pathways enhancing the cell cycle, epithelial-mesenchymal transition, and cell motility. Furthermore, increases in solid-stress pressure associated with cell hyperproliferation activate tumorigenic pathways in the healthy epithelial cells compressed by the neighboring tumor. The underlying molecular mechanisms of the translation of a mechanical signal into a tumor inducing biochemical signal are based on mechanically induced protein conformational changes that activate classical tumorigenic signaling pathways. Understanding these mechanisms will be important for the development of innovative treatments to target such mechanical anomalies in cancer. PMID- 29467177 TI - Extended Vernalization Regulates Inflorescence Fate in Arabis alpina by Stably Silencing PERPETUAL FLOWERING1. AB - The alpine perennial Arabis alpina initiates flower buds during prolonged exposure to cold. In the accession Pajares, we demonstrate that the length of vernalization influences flowering time and inflorescence fate but does not affect the axillary branches that maintain vegetative growth. The expression of floral organ identity genes gradually increases in the main shoot apex during vernalization, correlating with an increase in floral commitment. In northern Arabidopsis (Arabidopsis thaliana) accessions, the length of vernalization modulates the stable silencing of the floral repressor FLOWERING LOCUS C (FLC). We demonstrate that expression of PERPETUAL FLOWERING1 (PEP1), the ortholog of FLC in A. alpina, is similarly influenced by the duration of the exposure to cold. Extended vernalization results in stable silencing of PEP1 in the inflorescence. In contrast, insufficient vernalization leads to PEP1 reactivation after cold treatment, which correlates with delayed flowering and the appearance of floral reversion phenotypes such as bracts and vegetative inflorescence branches. Floral reversion phenotypes are reduced in the pep1-1 mutant, suggesting that PEP1 regulates the fate of the inflorescence after vernalization. The effect of vernalization duration on stable silencing of PEP1 is specific to meristems that initiate flowering during cold treatment. Extended vernalization fails to silence PEP1 in young seedlings and axillary branches that arise from buds initiated during cold treatment, which remain vegetative. We conclude that the duration of vernalization in A. alpina differentially regulates PEP1 in the inflorescence and axillary branches. PEP1 has a dual role regulating meristem fate; it prevents meristems from flowering and antagonizes inflorescence development after vernalization. PMID- 29467178 TI - A Putative Protein O-Fucosyltransferase Facilitates Pollen Tube Penetration through the Stigma-Style Interface. AB - During pollen-pistil interactions in angiosperms, the male gametophyte (pollen) germinates to produce a pollen tube. To fertilize ovules located within the female pistil, the pollen tube must physically penetrate specialized tissues. Whereas the process of pollen tube penetration through the pistil has been anatomically well described, the genetic regulation remains poorly understood. In this study, we identify a novel Arabidopsis (Arabidopsis thaliana) gene, O FUCOSYLTRANSFERASE1 (AtOFT1), which plays a key role in pollen tube penetration through the stigma-style interface. Semi-in vivo growth assays demonstrate that oft1 mutant pollen tubes have a reduced ability to penetrate the stigma-style interface, leading to a nearly 2,000-fold decrease in oft1 pollen transmission efficiency and a 5- to 10-fold decreased seed set. We also demonstrate that AtOFT1 is localized to the Golgi apparatus, indicating its potential role in cellular glycosylation events. Finally, we demonstrate that AtOFT1 and other similar Arabidopsis genes represent a novel clade of sequences related to metazoan protein O-fucosyltransferases and that mutation of residues that are important for O-fucosyltransferase activity compromises AtOFT1 function in vivo. The results of this study elucidate a physiological function for AtOFT1 in pollen tube penetration through the stigma-style interface and highlight the potential importance of protein O-glycosylation events in pollen-pistil interactions. PMID- 29467180 TI - Ocular neuromyotonia. AB - Ocular neuromyotonia is a rare, albeit treatable, ocular motor disorder, characterised by recurrent brief episodes of diplopia due to tonic extraocular muscle contraction. Ephaptic transmission in a chronically damaged ocular motor nerve is the possible underlying mechanism. It usually improves with carbamazepine. A 53-year-old woman presented with a 4-month history of recurrent episodes of binocular vertical diplopia (up to 40/day), either spontaneously or after sustained downward gaze. Between episodes she had a mild left fourth nerve palsy. Sustained downward gaze consistently triggered downward left eye tonic deviation, lasting around 1 min. MR scan of the brain was normal. She improved on starting carbamazepine but developed a rash that necessitated stopping the drug. Switching to lacosamide controlled her symptoms.

PMID- 29467179 TI - Toward an integrated map of genetic interactions in cancer cells. AB - Cancer genomes often harbor hundreds of molecular aberrations. Such genetic variants can be drivers or passengers of tumorigenesis and create vulnerabilities for potential therapeutic exploitation. To identify genotype-dependent vulnerabilities, forward genetic screens in different genetic backgrounds have been conducted. We devised MINGLE, a computational framework to integrate CRISPR/Cas9 screens originating from different libraries building on approaches pioneered for genetic network discovery in model organisms. We applied this method to integrate and analyze data from 85 CRISPR/Cas9 screens in human cancer cells combining functional data with information on genetic variants to explore more than 2.1 million gene-background relationships. In addition to known dependencies, we identified new genotype-specific vulnerabilities of cancer cells. Experimental validation of predicted vulnerabilities identified GANAB and PRKCSH as new positive regulators of Wnt/beta-catenin signaling. By clustering genes with similar genetic interaction profiles, we drew the largest genetic network in cancer cells to date. Our scalable approach highlights how diverse genetic screens can be integrated to systematically build informative maps of genetic interactions in cancer, which can grow dynamically as more data are included. PMID- 29467182 TI - Somatic IL4R mutations in primary mediastinal large B-cell lymphoma lead to constitutive JAK-STAT signaling activation. AB - Primary mediastinal large B-cell lymphoma (PMBCL) is a distinct subtype of diffuse large B-cell lymphoma thought to arise from thymic medullary B cells. Gene mutations underlying the molecular pathogenesis of the disease are incompletely characterized. Here, we describe novel somatic IL4R mutations in 15 of 62 primary cases of PMBCL (24.2%) and in all PMBCL-derived cell lines tested. The majority of mutations (11/21; 52%) were hotspot single nucleotide variants in exon 8, leading to an I242N amino acid change in the transmembrane domain. Functional analyses establish this mutation as gain of function leading to constitutive activation of the JAK-STAT pathway and upregulation of downstream cytokine expression profiles and B cell-specific antigens. Moreover, expression of I242N mutant IL4R in a mouse xenotransplantation model conferred growth advantage in vivo. The pattern of concurrent mutations within the JAK-STAT signaling pathway suggests additive/synergistic effects of these gene mutations contributing to lymphomagenesis. Our data establish IL4R mutations as novel driver alterations and provide a strong preclinical rationale for therapeutic targeting of JAK-STAT signaling in PMBCL. PMID- 29467183 TI - The search for new antithrombotic mechanisms and therapies that may spare hemostasis. AB - Current antithrombotic drugs, including widely used antiplatelet agents and anticoagulants, are associated with significant bleeding risk. Emerging experimental evidence suggests that the molecular and cellular mechanisms of hemostasis and thrombosis can be separated, thereby increasing the possibility of new antithrombotic therapeutic targets with reduced bleeding risk. We review new coagulation and platelet targets and highlight the interaction between integrin alphaMbeta2 (Mac-1, CD11b/CD18) on leukocytes and GPIbalpha on platelets that seems to distinguish thrombosis from hemostasis. PMID- 29467184 TI - Low catalase expression confers redox hypersensitivity and identifies an indolent clinical behavior in CLL. AB - B-cell receptor (BCR) signaling is a key determinant of variable clinical behavior and a target for therapeutic interventions in chronic lymphocytic leukemia (CLL). Endogenously produced H2O2 is thought to fine-tune the BCR signaling by reversibly inhibiting phosphatases. However, little is known about how CLL cells sense and respond to such redox cues and what effect they have on CLL. We characterized the response of BCR signaling proteins to exogenous H2O2 in cells from patients with CLL, using phosphospecific flow cytometry. Exogenous H2O2 in the absence of BCR engagement induced a signaling response of BCR proteins that was higher in CLL with favorable prognostic parameters and an indolent clinical course. We identified low catalase expression as a possible mechanism accounting for redox signaling hypersensitivity. Decreased catalase could cause an escalated accumulation of exogenous H2O2 in leukemic cells with a consequent greater inhibition of phosphatases and an increase of redox signaling sensitivity. Moreover, lower levels of catalase were significantly associated with a slower progression of the disease. In leukemic cells characterized by redox hypersensitivity, we also documented an elevated accumulation of ROS and an increased mitochondrial amount. Taken together, our data identified redox sensitivity and metabolic profiles that are linked to differential clinical behavior in CLL. This study advances our understanding of the redox and signaling heterogeneity of CLL and provides the rationale for the development of therapies targeting redox pathways in CLL.

PMID- 29467186 TI - A pilot study of a Medication Rationalization (MERA) intervention. AB - BACKGROUND: Many seriously ill and frail inpatients receive potentially inappropriate or harmful medications and do not receive medications for symptoms of advanced illness. We developed and piloted an interprofessional Medication Rationalization (MERA) approach to deprescribing inappropriate medications and prescribing appropriate comfort medications. METHODS: We conducted a single centre pilot study of inpatients at risk of 6-month mortality from advanced age or morbidity. The MERA team reviewed the patients' medications and made recommendations on the basis of guidelines. We measured end points for feasibility, acceptability, efficiency and effectiveness. RESULTS: We enrolled 61 of 115 (53%) eligible patients with a mean age of 79.6 years (standard deviation [SD] 11.7 yr). Patients were taking an average of 11.5 (SD 5.2) medications before admission and had an average of 2.1 symptoms with greater than 6/10 severity on the revised Edmonton Symptom Assessment System. The MERA team recommended 263 medication changes, of which 223 (85%) were accepted by both the medical team and the patient. MERA team's recommendations resulted in the discontinuation of 162 medications (mean 3.1 per patient), dose changes for 48 medications (mean 0.9 per patient) and the addition of 13 medications (mean 0.2 per patient). Patients who received the MERA intervention stopped significantly more inappropriate medications than similar non-MERA comparison patients for whom data were collected retrospectively (3.1 v. 0.9 medications per patient, p < 0.01). The MERA approach was highly acceptable to patients and medical team members. INTERPRETATION: The MERA intervention is feasible, acceptable, efficient and possibly effective for changing medication use among seriously ill and frail elderly inpatients. Scalability and effectiveness may be improved through automation and integration with medication reconciliation programs. PMID- 29467187 TI - Drosophila Larval Brain Neoplasms Present Tumour-Type Dependent Genome Instability. AB - Single nucleotide polymorphisms (SNPs) and copy number variants (CNVs) are found at different rates in human cancer. To determine if these genetic lesions appear in Drosophila tumors we have sequenced the genomes of 17 malignant neoplasms caused by mutations in l(3)mbt, brat, aurA, or lgl We have found CNVs and SNPs in all the tumors. Tumor-linked CNVs range between 11 and 80 per sample, affecting between 92 and 1546 coding sequences. CNVs are in average less frequent in l(3)mbt than in brat lines. Nearly half of the CNVs fall within the 10 to 100Kb range, all tumor samples contain CNVs larger that 100 Kb and some have CNVs larger than 1Mb. The rates of tumor-linked SNPs change more than 20-fold depending on the tumor type: at late time points brat, l(3)mbt, and aurA and lgl lines present median values of SNPs/Mb of exome of 0.16, 0.48, and 3.6, respectively. Higher SNP rates are mostly accounted for by C > A transversions, which likely reflect enhanced oxidative stress conditions in the affected tumors. Both CNVs and SNPs turn over rapidly. We found no evidence for selection of a gene signature affected by CNVs or SNPs in the cohort. Altogether, our results show that the rates of CNVs and SNPs, as well as the distribution of CNV sizes in this cohort of Drosophila tumors are well within the range of those reported for human cancer. Genome instability is therefore inherent to Drosophila malignant neoplastic growth at a variable extent that is tumor type dependent. PMID- 29467188 TI - Mapping and Predicting Non-Linear Brassica rapa Growth Phenotypes Based on Bayesian and Frequentist Complex Trait Estimation. AB - Predicting phenotypes based on genotypes and understanding the effects of complex multi-locus traits on plant performance requires a description of the underlying developmental processes, growth trajectories, and their genomic architecture. Using data from Brassica rapa genotypes grown in multiple density settings and seasons, we applied a hierarchical Bayesian Function-Valued Trait (FVT) approach to fit logistic growth curves to leaf phenotypic data (length and width) and characterize leaf development. We found evidence of genetic variation in phenotypic plasticity of rate and duration of leaf growth to growing season. In contrast, the magnitude of the plastic response for maximum leaf size was relatively small, suggesting that growth dynamics vs. final leaf sizes have distinct patterns of environmental sensitivity. Consistent with patterns of phenotypic plasticity, several QTL-by-year interactions were significant for parameters describing leaf growth rates and durations but not leaf size. In comparison to frequentist approaches for estimating leaf FVT, Bayesian trait estimation resulted in more mapped QTL that tended to have greater average LOD scores and to explain a greater proportion of trait variance. We then constructed QTL-based predictive models for leaf growth rate and final size using data from one treatment (uncrowded plants in one growing season). Models successfully predicted non-linear developmental phenotypes for genotypes not used in model construction and, due to a lack of QTL-by-treatment interactions, predicted phenotypes across sites differing in plant density. PMID- 29467189 TI - Synopsis of the SOFL Plant-Specific Gene Family. AB - SUPPRESSOR OF PHYB-4#5DOMINANT (sob5-D) was previously identified as a suppressor of the phyB-4 long-hypocotyl phenotype in Arabidopsis thaliana Overexpression of SOB5 conferred dwarf phenotypes similar to those observed in plants containing elevated levels of cytokinin (CK) nucleotides and nucleosides. Two SOB-FIVE- LIKE (SOFL) proteins, AtSOFL1 and AtSOFL2, which are more similar at the protein level to each other than they are to SOB5, conferred similar phenotypes to the sob5-D mutant when overexpressed. We used protein sequences of founding SOFL gene family members to perform database searches and identified a total of 289 SOFL homologs in genomes of 89 angiosperm species. Phylogenetic analysis results implied that the SOFL gene family emerged during the expansion of angiosperms and later evolved into four distinct clades. Among the newly identified gene family members are four previously unreported Arabidopsis SOFLs Multiple sequence alignment of the 289 SOFL protein sequences revealed two highly conserved domains; SOFL-A and SOFL-B. We used overexpression and site-directed mutagenesis studies to demonstrate that SOFL domains are necessary for SOB5 and AtSOFL1's overexpression phenotypes. Examination of the subcellular localization patterns of founding Arabidopsis thaliana SOFLs suggested they may be localized in the cytoplasm and/or the nucleus. Overall, we report that SOFLs are a plant-specific gene family characterized by two conserved domains that are important for function. PMID- 29467190 TI - Examination of Signatures of Recent Positive Selection on Genes Involved in Human Sialic Acid Biology. AB - Sialic acids are nine carbon sugars ubiquitously found on the surfaces of vertebrate cells and are involved in various immune response-related processes. In humans, at least 58 genes spanning diverse functions, from biosynthesis and activation to recycling and degradation, are involved in sialic acid biology. Because of their role in immunity, sialic acid biology genes have been hypothesized to exhibit elevated rates of evolutionary change. Consistent with this hypothesis, several genes involved in sialic acid biology have experienced higher rates of non-synonymous substitutions in the human lineage than their counterparts in other great apes, perhaps in response to ancient pathogens that infected hominins millions of years ago (paleopathogens). To test whether sialic acid biology genes have also experienced more recent positive selection during the evolution of the modern human lineage, reflecting adaptation to contemporary cosmopolitan or geographically-restricted pathogens, we examined whether their protein-coding regions showed evidence of recent hard and soft selective sweeps. This examination involved the calculation of four measures that quantify changes in allele frequency spectra, extent of population differentiation, and haplotype homozygosity caused by recent hard and soft selective sweeps for 55 sialic acid biology genes using publicly available whole genome sequencing data from 1,668 humans from three ethnic groups. To disentangle evidence for selection from confounding demographic effects, we compared the observed patterns in sialic acid biology genes to simulated sequences of the same length under a model of neutral evolution that takes into account human demographic history. We found that the patterns of genetic variation of most sialic acid biology genes did not significantly deviate from neutral expectations and were not significantly different among genes belonging to different functional categories. Those few sialic acid biology genes that significantly deviated from neutrality either experienced soft sweeps or population-specific hard sweeps. Interestingly, while most hard sweeps occurred on genes involved in sialic acid recognition, most soft sweeps involved genes associated with recycling, degradation and activation, transport, and transfer functions. We propose that the lack of signatures of recent positive selection for the majority of the sialic acid biology genes is consistent with the view that these genes regulate immune responses against ancient rather than contemporary cosmopolitan or geographically restricted pathogens. PMID- 29467191 TI - Targeted next-generation sequencing in blast phase myeloproliferative neoplasms. AB - Among 248 consecutive patients with blast phase myeloproliferative neoplasm (MPN BP), DNA collected at the time of blast transformation was available in 75 patients (median age, 66 years; 64% men). MPN-BP followed primary myelofibrosis in 39 patients, essential thrombocythemia in 20 patients, and polycythemia vera in 16 patients. A myeloid neoplasm-relevant 33-gene panel was used for next generation sequencing. Driver mutation distribution was JAK2 57%, CALR 20%, MPL 9%, and triple-negative 13%. Sixty-four patients (85%) harbored other mutations/variants, including 37% with >=3 mutations; most frequent were ASXL1 47%, TET2 19%, RUNX1 17%, TP53 16%, EZH2 15%, and SRSF2 13%; relative mutual exclusivity was expressed by TP53, EZH2, LNK, RUNX1, SRSF2, and NRAS/KRAS mutations. Paired chronic-blast phase sample analysis was possible in 19 patients and revealed more frequent blast phase acquisition of ASXL1, EZH2, LNK, TET2, TP53, and PTPN11 mutations/variants. In multivariable analysis, RUNX1 and PTPN11 mutations/variants were associated with shorter survival duration; respective hazard ratios (HRs) (95% confidence interval [CI]) were 2.1 (95% CI, 1.1-3.8) and 3.0 (95% CI, 1.1-6.6). An all-inclusive multivariable analysis confirmed the prognostic relevance of RUNX1 mutations (HR, 1.9; 95% CI, 1.5-5.5) and also showed additional contribution from a treatment strategy that includes transplant or induction of complete or near-complete remission (HR, 0.3; 95% CI, 0.2-0.5). The current study points to specific mutations that might bear pathogenetic relevance for leukemic transformation in MPN and also suggest an adverse survival effect of RUNX1 mutations. PMID- 29467192 TI - Combination of the low anticoagulant heparin CX-01 with chemotherapy for the treatment of acute myeloid leukemia. AB - Relapses in acute myelogenous leukemia (AML) are a result of quiescent leukemic stem cells (LSCs) in marrow stromal niches, where they resist chemotherapy. LSCs employ CXCL12/CXCR4 to home toward protective marrow niches. Heparin disrupts CXCL12-mediated sequestration of cells in the marrow. CX-01 is a low anticoagulant heparin derivative. In this pilot study, we combined CX-01 with chemotherapy for the treatment of AML. Induction consisted of cytarabine and idarubicin (7 + 3) with CX-01. Twelve patients were enrolled (median age, 56 years; 3 women). Three, 5, and 4 patients had good-, intermediate-, and poor-risk disease, respectively. Day 14 bone marrows were available on 11 patients and were aplastic in all without detectable leukemia. Eleven patients (92%) had morphologic complete remission after 1 induction (CR1). Eight patients were alive at a median follow-up of 24 months (4 patients in CR1). Three patients received an allogeneic stem cell transplant in CR1. Median disease-free survival was 14.8 months. Median overall survival was not attained at the maximum follow-up time of 29.4 months. No CX-01-associated serious adverse events occurred. Median day to an untransfused platelet count of at least 20 * 109/L was 21. CX-01 is well tolerated when combined with intensive therapy for AML and appears associated with enhanced count recovery and treatment efficacy. PMID- 29467193 TI - Adaptation of Amoeba Plate Test To Recover Legionella Strains from Clinical Samples. AB - The isolation of Legionella from respiratory samples is the gold standard for diagnosis of Legionnaires' disease (LD) and enables epidemiological studies and outbreak investigations. The purpose of this work was to adapt and to evaluate the performance of an amoebic coculture procedure (the amoeba plate test [APT]) for the recovery of Legionella strains from respiratory samples, in comparison with axenic culture and liquid-based amoebic coculture (LAC). Axenic culture, LAC, and APT were prospectively performed with 133 respiratory samples from patients with LD. The sensitivities and times to results for the three techniques were compared. Using the three techniques, Legionella strains were isolated in 46.6% (n = 62) of the 133 respiratory samples. The sensitivity of axenic culture was 42.9% (n = 57), that of LAC was 30.1% (n = 40), and that of APT was 36.1% (n = 48). Seven samples were positive by axenic culture only; for those samples, there were <10 colonies in total. Five samples, all sputum samples, were positive by an amoebic procedure only (5/5 samples by APT and 2/5 samples by LAC); all had overgrowth by oropharyngeal flora with axenic culture. The combination of axenic culture with APT yielded a maximal isolation rate (i.e., 46.6%). Overall, the APT significantly reduced the median time for Legionella identification to 4 days, compared with 7 days for LAC (P < 0.0001). The results of this study support the substitution of LAC by APT, which could be implemented as a second-line technique for culture-negative samples and samples with microbial overgrowth, especially sputum samples. The findings provide a logical basis for further studies in both clinical and environmental settings.

AB - Clostridium difficile multilocus sequence type 37 (ST37), which mainly corresponds to ribotype 017, has been a dominant genotype circulating in China. In this study, we report the use of matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF MS) to analyze and characterize 204 C. difficile clinical isolates, including 49 ST37 and 155 non-ST37 isolates collected in China and other countries. The distributions of two major protein peaks (m/z 3,242 and 3,286) were significantly different between ST37 and non ST37 prototype strains and clinical isolates. This difference was reproducible when analysis was performed on different colonies in different runs. This finding was repeated and confirmed by both bioMerieux Vitek MS and Bruker Microflex LT systems on isolates recovered from a variety of geographic regions worldwide. The combination of the two peaks was present in 47 of 49 ST37 isolates, resulting in a sensitivity of 95.9%. In contrast, the peak combination was absent in 153 of 155 non-ST37 isolates, resulting in a specificity of 98.7%. Our results suggest that MALDI-TOF MS is a rapid and reliable tool to identify C. difficile genotype ST37. Work is in progress to characterize the two molecules having peaks at m/z 3,242 and 3,286, which appear to be specific to C. difficile genotype ST37.

AB - The current diagnostic marker of Lyme neuroborreliosis (LNB), the Borrelia burgdorferisensu lato antibody index (AI) in the cerebrospinal fluid (CSF), has insufficient sensitivity in the early phase of LNB. We aimed to elucidate the diagnostic value of PCR for B. burgdorferisensu lato in CSF from children with symptoms suggestive of LNB and to explore B. burgdorferisensu lato genotypes associated with LNB in children. Children were prospectively included in predefined groups with a high or low likelihood of LNB based on diagnostic guidelines (LNB symptoms, CSF pleocytosis, and B. burgdorferisensu lato antibodies) or the detection of other causative agents. CSF samples were analyzed by two B. burgdorferisensu lato-specific real-time PCR assays and, if B. burgdorferisensu lato DNA was detected, were further analyzed by five singleplex real-time PCR assays for genotype determination. For children diagnosed as LNB patients (58 confirmed and 18 probable) (n = 76) or non-LNB controls (n = 28), the sensitivity and specificity of PCR for B. burgdorferisensu lato in CSF were 46% and 100%, respectively. B. burgdorferisensu lato DNA was detected in 26/58 (45%) children with AI-positive LNB and in 7/12 (58%) children with AI-negative LNB and symptoms of short duration. Among 36 children with detectable B. burgdorferisensu lato DNA, genotyping indicated Borrelia garinii (n = 27) and non B. garinii (n = 1) genotypes, while 8 samples remained untyped. Children with LNB caused by B. garinii did not have a distinct clinical picture. The rate of detection of B. burgdorferisensu lato DNA in the CSF of children with LNB was higher than that reported previously. PCR for B. burgdorferisensu lato could be a useful supplemental diagnostic tool in unconfirmed LNB cases with symptoms of short duration. B. garinii was the predominant genotype in children with LNB. PMID- 29467196 TI - Specific Activation of the Alternative Cardiac Promoter of Cacna1c by the Mineralocorticoid Receptor. AB - RATIONALE: The MR (mineralocorticoid receptor) antagonists belong to the current therapeutic armamentarium for the management of cardiovascular diseases, but the mechanisms conferring their beneficial effects are poorly understood. Part of the cardiovascular effects of MR is because of the regulation of L-type Cav1.2 Ca2+ channel expression, which is generated by tissue-specific alternative promoters as a long cardiac or short vascular N-terminal transcripts. OBJECTIVE: To analyze the molecular mechanisms by which aldosterone, through MR, modulates Cav1.2 expression and function in a tissue-specific manner. METHODS AND RESULTS: In primary cultures of neonatal rat ventricular myocytes, aldosterone exposure for 24 hours increased in a concentration-dependent manner long cardiac Cav1.2 N terminal transcripts expression at both mRNA and protein levels, correlating with enhanced concentration-, time-, and MR-dependent P1-promoter activity. In silico analysis and mutagenesis identified MR interaction with both specific activating and repressing DNA-binding elements on the P1-promoter. The relevance of this regulation is confirmed both ex and in vivo in transgenic mice harboring the luciferase reporter gene under the control of the cardiac P1-promoter. Moreover, we show that this cis-regulatory mechanism is not limited to the heart. Indeed, in smooth muscle cells from different vascular beds, in which the short vascular Cav1.2 N-terminal transcripts is normally the major isoform, we found that MR signaling activates long cardiac Cav1.2 N-terminal transcripts expression through P1-promoter activation, leading to vascular contractile dysfunction. These results were further corroborated in hypertensive aldosterone/salt rodent models, showing notably a positive correlation between blood pressure and cardiac P1 promoter activity in aorta. This new vascular long cardiac Cav1.2 N-terminal transcripts molecular signature reduced sensitivity to the Ca2+ channel blocker, nifedipine, in aldosterone-treated vessels. CONCLUSIONS: Our results reveal that MR acts as a transcription factor to translate aldosterone signal into specific cardiac P1-promoter activation that might influence the therapeutic outcome of cardiovascular diseases.

AB - RATIONALE: Reduction of infarct size by remote ischemic perconditioning (perRIC) is evident only after several hours reperfusion. OBJECTIVE: To develop a potential real-time estimate of cardioprotection by perRIC, we have analyzed the time course of ST-segment elevation. METHODS AND RESULTS: Anesthetized open-chest pigs were subjected to 60-minute coronary occlusion and 180-minute reperfusion (placebo; n=19). PerRIC (n=18; 4*5 min/5 min hindlimb occlusion/reperfusion) was induced 20 minutes after coronary occlusion. Regional myocardial blood flow was measured with microspheres, areas of no-reflow with thioflavin-S, area at risk with blue dye, and infarct size with triphenyl tetrazolium chloride staining. Phosphorylation of protein kinase B alpha/beta/gamma, extracellular signal regulated kinase 1/2, and signal transducer and activator of transcription 3 was determined by Western blot. ST-segment elevation was analyzed in a V2-like ECG lead at baseline, 5- and 55-minute coronary occlusion, and 10-, 30-, 60-, and 120 minute reperfusion. Transmural blood flow at 5-minute coronary occlusion was not different between perRIC (0.029+/-0.015 mL/min per gram; mean+/-SD) and placebo (0.024+/-0.018 mL/min per gram) as was area at risk (perRIC: 24+/-6% of the left ventricle; placebo: 21+/-4%). Areas of no-reflow tended to be smaller with perRIC (9+/-12% of area at risk versus 15+/-14% with placebo; P=0.13). Infarct size with perRIC was 23+/-12% of area at risk versus 40+/-11% with placebo (P<0.001). PerRIC increased phosphorylation of signal transducer and activator of transcription 3 at 120-minute reperfusion by 196+/-142% versus 109+/-120% with placebo (P=0.047). The time courses of ST-segment elevation in perRIC and placebo protocols, respectively, were different (P=0.017). With similar ST-segment elevation at 5-minute coronary occlusion (perRIC 282+/-34 uV; placebo 259+/-28 uV), partial recovery of ST-segment elevation between 5- and 55-minute coronary occlusion was more pronounced with perRIC than placebo (by 111+/-84 versus 15+/ 94 uV; P=0.028). CONCLUSION: Infarct size reduction by perRIC is reflected in the ST-segment elevation during coronary occlusion in pigs, supporting the notion of protection from ischemic injury. PMID- 29467199 TI - Living with breathlessness: a systematic literature review and qualitative synthesis. AB - What is the experience of people living with breathlessness due to medical conditions, those caring for them and those treating them, with regard to quality of life and the nature of clinical interactions?Electronic databases (Ovid MEDLINE, Embase, CINAHL Plus and PsycINFO) were searched (January 1987 to October 2017; English language), for qualitative studies exploring the experience of chronic breathlessness (patients, carers and clinicians). Two independent reviewers screened titles, abstracts and papers retrieved against inclusion criteria. Disagreements were resolved with a third reviewer. Primary qualitative data were extracted and synthesised using thematic synthesis.Inclusion and synthesis of 101 out of 2303 international papers produced four descriptive themes: 1) widespread effects of breathlessness; 2) coping; 3) help-seeking behaviour; and 4) clinicians' responsiveness to the symptom of breathlessness. The themes were combined to form the concept of "breathing space", to show how engaged coping and appropriate help-seeking (patient) and attention to symptom (clinician) helps maximise the patient's quality of living with breathlessness.Breathlessness has widespread impact on both patient and carer and affects breathing space. The degree of breathing space is influenced by interaction between the patient's coping style, their help-seeking behaviour and their clinician's responsiveness to breathlessness itself, in addition to managing the underlying disease. PMID- 29467198 TI - Endothelial TFEB (Transcription Factor EB) Positively Regulates Postischemic Angiogenesis. AB - RATIONALE: Postischemic angiogenesis is critical to limit the ischemic tissue damage and improve the blood flow recovery. The regulation and the underlying molecular mechanisms of postischemic angiogenesis are not fully unraveled. TFEB (transcription factor EB) is emerging as a master gene for autophagy and lysosome biogenesis. However, the role of TFEB in vascular disease is less understood. OBJECTIVE: We aimed to determine the role of endothelial TFEB in postischemic angiogenesis and its underlying molecular mechanism. METHODS AND RESULTS: In primary human endothelial cells (ECs), serum starvation induced TFEB nuclear translocation. VEGF (vascular endothelial growth factor) increased TFEB expression level and nuclear translocation. Utilizing genetically engineered EC specific TFEB transgenic and KO (knockout) mice, we investigated the role of TFEB in postischemic angiogenesis in the mouse hindlimb ischemia model. We observed improved blood perfusion and increased capillary density in the EC-specific TFEB transgenic mice compared with the wild-type littermates. Furthermore, blood flow recovery was attenuated in EC-TFEB KO mice compared with control mice. In aortic ring cultures, the TFEB transgene significantly increased vessel sprouting, whereas TFEB deficiency impaired the vessel sprouting. In vitro, adenovirus mediated TFEB overexpression promoted EC tube formation, migration, and survival, whereas siRNA-mediated TFEB knockdown had the opposite effect. Mechanistically, TFEB activated AMPK (AMP-activated protein kinase)-alpha signaling and upregulated autophagy. Through inactivation of AMPKalpha or inhibition of autophagy, we demonstrated that the AMPKalpha and autophagy are necessary for TFEB to regulate angiogenesis in ECs. Finally, the positive effect of TFEB on AMPKalpha activation and EC tube formation was mediated by TFEB-dependent transcriptional upregulation of MCOLN1 (mucolipin-1). CONCLUSIONS: In summary, our data demonstrate that TFEB is a positive regulator of angiogenesis through activation of AMPKalpha and autophagy, suggesting that TFEB constitutes a novel molecular target for ischemic vascular disease. PMID- 29467200 TI - Effectiveness versus efficacy trials in COPD: how study design influences outcomes and applicability. AB - Guidelines for chronic obstructive pulmonary disease (COPD) management are based largely on results from double-blind randomised controlled trials (RCTs) of efficacy. These trials have high internal validity and test whether a drug is efficacious, but they are conducted in highly selected populations that may differ significantly from patients with COPD seen in routine practice.We compared the baseline characteristics, healthcare use and outcomes between the Salford Lung Study (SLS), an open-label effectiveness RCT, with six recent large-scale efficacy RCTs. We also calculated the proportion of SLS patients who would have been eligible for inclusion in an efficacy RCT by applying the inclusion criteria used in efficacy trials of combination treatments.SLS patients were older, included more females and more current smokers, had more comorbidities (including asthma), and had more often experienced exacerbations prior to inclusion. In the SLS, rates of moderate or severe exacerbations, incidence of overall serious adverse events (SAEs), and SAEs of pneumonia were more frequent. A maximum of 30% of patients enrolled in the SLS would have been eligible for a phase IIIa regulatory exacerbation study.Patients in large COPD efficacy RCTs have limited representativeness compared with an effectiveness trial. This should be considered when interpreting efficacy RCT outcomes and their inclusion into guidelines. PMID- 29467201 TI - Small airways dysfunction: the link between allergic rhinitis and allergic asthma. AB - Abnormal airway reactivity and overproduction of nitric oxide (NO) occurring in small airways have been found in asthma. If the "one airway, one disease" concept is consistent, such dysfunctions should also be detected in the peripheral airways of patients suffering from allergic rhinitis.We investigated whether peripheral airway reactivity and NO overproduction could be documented in distal airways in patients with allergic rhinitis. Exhaled NO fraction (FeNO) and the slope (S) of phase III of the single-breath washout test (SBWT) of helium (He) and sulfur hexafluoride (SF6) were measured in 31 patients with allergic asthma, 23 allergic rhinitis patients and 24 controls, before and after sputum induction. SBWT is sensitive to airway calibre change occurring in the lung periphery.The FeNO decrease was more significant in asthma and rhinitis than in controls ( 55.1% and -50.0%, respectively, versus -40.8%) (p=0.007 and p=0.029, respectively). SSF6 and SHe increased in all groups. Change in SHe (DeltaSHe) > DeltaSSF6 was observed in rhinitis (p=0.004) and asthma (p<0.001), whereas DeltaSSF6 = DeltaSHe in controls (p=0.431).This study provides evidence of peripheral airway dysfunction in patients with allergic rhinitis quite similar to that described in asthma. Furthermore, a large proportion of the increased NO production reported in allergic rhinitis appears to originate in the peripheral airways. PMID- 29467203 TI - Sarcoidosis mortality in Sweden: a population-based cohort study. AB - We aimed to investigate sarcoidosis mortality in a large, population-based cohort, taking into account disease heterogeneity.Individuals with incident sarcoidosis (n=8207) were identified from the Swedish National Patient Register using International Classification of Disease codes (2003-2013). In a subset, cases receiving treatment +/-3 months from diagnosis were identified from the Prescribed Drug Register. Nonsarcoidosis comparators from the general population were matched to cases 10:1 on birth year, sex and county. Individuals were followed for all-cause death in the Cause of Death Register. Adjusted mortality rates, rate differences and hazard ratios (HRs) were estimated, stratifying by age, sex and treatment status.The mortality rate was 11.0 per 1000 person-years in sarcoidosis versus 6.7 in comparators (rate difference 2.7 per 1000 person years). The HR for death was 1.61 (95% CI 1.47-1.76), with no large variation by age or sex. For cases not receiving treatment within the first 3 months, the HR was 1.13 (95% CI 0.94-1.35). The HR was 2.34 (95% CI 1.99-2.75) for those receiving treatment.Individuals with sarcoidosis are at a higher risk of death compared to the general population. For the majority, the increased risk is small. However, patients whose disease leads to treatment around diagnosis have a two-fold increased risk of death. Future interventions should focus on this vulnerable group. PMID- 29467204 TI - The role of air pollution and lung function in cognitive impairment. AB - Air pollution has been associated with impaired lung and cognitive function, especially impairment in visuo-construction performance (VCP). In this article, we evaluate whether the effect of air pollution on VCP is mediated by lung function.We used data from the SALIA cohort (baseline 1985-1994 and follow-up 2007-2010) including 587 women aged 55 years at baseline. Particulate matter (PM) and nitrogen dioxide (NO2) exposures at baseline were estimated via land-use regression models. Lung function was characterised by averages between baseline and follow-up. We used age- and height-controlled Global Lung Initiative (GLI) z scores of forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC) and FEV1/FVC. VCP was assessed at follow-up with the CERAD-Plus neuropsychological test battery and causal mediation analysis was conducted.An increase of one interquartile range in FEV1 and FVC was positively associated with VCP (beta=0.18 (95% CI 0.02-0.34) and beta=0.23 (95% CI 0.07-0.39), respectively). The proportion of the association between NO2 on VCP mediated by FEV1 was 6.2% and this was higher in never smokers (7.2%) and non-carriers of the APOE-epsilon4 allele (11.2%). However, none of the mediations were statistically significant.In conclusion, air pollution associated VCP was partially mediated by lung function. Further studies on the mechanisms underlying this pathway are required to develop new strategies to prevent air pollution induced cognitive impairment. PMID- 29467202 TI - Primary ciliary dyskinesia with normal ultrastructure: three-dimensional tomography detects absence of DNAH11. AB - In primary ciliary dyskinesia (PCD), motile ciliary dysfunction arises from ciliary defects usually confirmed by transmission electron microscopy (TEM). In 30% of patients, such as those with DNAH11 mutations, apparently normal ultrastructure makes diagnosis difficult. Genetic analysis supports diagnosis, but may not identify definitive causal variants. Electron tomography, an extension of TEM, produces three-dimensional ultrastructural ciliary models with superior resolution to TEM. Our hypothesis is that tomography using existing patient samples will enable visualisation of DNAH11-associated ultrastructural defects. Dual axis tomograms from araldite-embedded nasal cilia were collected in 13 PCD patients with normal ultrastructure (DNAH11 n=7, HYDIN n=2, CCDC65 n=3 and DRC1 n=1) and six healthy controls, then analysed using IMOD and Chimera software.DNAH11 protein is localised to the proximal ciliary region. Within this region, electron tomography indicated a deficiency of >25% of proximal outer dynein arm volume in all patients with DNAH11 mutations (n=7) compared to other patients with PCD and normal ultrastructure (n=6) and healthy controls (n=6). DNAH11 mutations cause a shared abnormality in ciliary ultrastructure previously undetectable by TEM. Advantageously, electron tomography can be used on existing diagnostic samples and establishes a structural abnormality where ultrastructural studies were previously normal.

AB - Historical data show that the risk of tuberculosis increases dramatically during adolescence, and young people face unique challenges in terms of case detection and effective treatment. However, little is known about the burden of tuberculosis among young people in the modern era. This study aimed to provide the first estimates of the global and regional incidence of tuberculosis among young people aged 10-24 years.Using the World Health Organization (WHO) database of tuberculosis notifications for 2012, we estimated the burden of tuberculosis among young people by WHO region. Adjustments were made for incomplete age disaggregation and underreporting, using supplementary data from several countries representing diverse tuberculosis epidemics.We estimate that 1.78 million (uncertainty interval (UI) 1.23-3.00 million) young people developed tuberculosis in 2012, accounting for 17% of all new tuberculosis cases globally. Young people in the WHO South East Asian Region (721 000, UI 473 000-1.35 million) and the WHO African Region (534 000, UI 359 000-912 000) experienced the greatest number of tuberculosis episodes.Young people suffer a considerable burden of tuberculosis. Age-specific burden of disease estimation for this age group is complicated by incomplete age disaggregation of tuberculosis data, highlighting the importance of continued surveillance system strengthening.

AB - The bile salt export pump (BSEP) is expressed at the canalicular domain of hepatocytes, where it mediates the elimination of monovalent bile salts into the bile. Inhibition of BSEP is considered a susceptibility factor for drug-induced liver injury that often goes undetected during nonclinical testing. Although in vitro assays exist for screening BSEP inhibition, a reliable and specific method for confirming Bsep inhibition in vivo would be a valuable follow up to a BSEP screening strategy, helping to put a translatable context around in vitro inhibition data, incorporating processes such as metabolism, protein binding, and other exposure properties that are lacking in most in vitro BSEP models. Here, we describe studies in which methods of quantitative intravital microscopy were used to identify dose-dependent effects of two known BSEP/Bsep inhibitors, 2-[4-[4 (butylcarbamoyl)-2-[(2,4-dichlorophenyl)sulfonylamino]phenoxy]-3 methoxyphenyl]acetic acid (AMG-009) and bosentan, on hepatocellular transport of the fluorescent bile salts cholylglycyl amidofluorescein and cholyl-lysyl fluorescein in rats. Results of these studies demonstrate that the intravital microscopy approach is capable of detecting Bsep inhibition at drug doses well below those found to increase serum bile acid levels, and also indicate that basolateral efflux transporters play a significant role in preventing cytosolic accumulation of bile acids under conditions of Bsep inhibition in rats. Studies of this kind can both improve our understanding of exposures needed to inhibit Bsep in vivo and provide unique insights into drug effects in ways that can improve our ability interpret animal studies for the prediction of human drug hepatotoxicity. PMID- 29467213 TI - Rare Variants in the ABCG2 Promoter Modulate In Vivo Activity. AB - ABCG2 encodes the breast cancer resistance protein (BCRP), an efflux membrane transporter important in the detoxification of xenobiotics. In the present study, the basal activity of the ABCG2 promoter in liver, kidney, intestine, and breast cell lines was examined using luciferase reporter assays. The promoter activities of reference and variant ABCG2 sequences were compared in human hepatocellular carcinoma cell (HepG2), human embryonic kidney cell (HEK293T), human colorectal carcinoma cell (HCT116), and human breast adenocarcinoma cell (MCF-7) lines. The ABCG2 promoter activity was strongest in the kidney and intestine cell lines. Four variants in the basal ABCG2 promoter (rs76656413, rs66664036, rs139256004, and rs59370292) decreased the promoter activity by 25%-50% in at least three of the four cell lines. The activity of these four variants was also examined in vivo using the hydrodynamic tail vein assay, and two single nucleotide polymorphisms (rs76656413 and rs59370292) significantly decreased in vivo liver promoter activity by 50%-80%. Electrophoretic mobility shift assays confirmed a reduction in nuclear protein binding to the rs59370292 variant probe, whereas the rs76656413 probe had a shift in transcription factor binding specificity. Although both rs59370292 and rs76656413 are rare variants in all populations, they could contribute to patient-level variation in ABCG2 expression in the kidney, liver, and intestine. PMID- 29467214 TI - Hepatic Transport of 25-Hydroxyvitamin D3 Conjugates: A Mechanism of 25 Hydroxyvitamin D3 Delivery to the Intestinal Tract. AB - Vitamin D3 is an important prohormone critical for maintaining calcium and phosphate homeostasis in the body and regulating drug-metabolizing enzymes and transporters. 25-Hydroxyvitamin D3 (25OHD3), the most abundant circulating metabolite of vitamin D3, is further transformed to the biologically active metabolite 1alpha,25-dihydroxyvitamin D3 (1alpha,25-(OH)2D3) by CYP27B1 in the kidney and extrarenal tissues, and to nonactive metabolites by other cytochrome P450 enzymes. In addition, 25OHD3 undergoes sulfation and glucuronidation in the liver, forming two major conjugative metabolites, 25OHD3-3-O-sulfate (25OHD3-S) and 25OHD3-3-O-glucuronide (25OHD3-G), both of which were detected in human blood and bile. Considering that the conjugates excreted into the bile may be circulated to and reabsorbed from the intestinal lumen, deconjugated to 25OHD3, and then converted to 1alpha,25-(OH)2D3, exerting local intestinal cellular effects, it is crucial to characterize enterohepatic transport mechanisms of 25OHD3-S and 25OHD3-G, and thereby understand and predict mechanisms of interindividual variability in mineral homeostasis. In the present study, with plasma membrane vesicle and cell-based transport studies, we showed that 25OHD3-G is a substrate of multidrug resistance proteins 2 and 3, OATP1B1, and OATP1B3, and that 25OHD3-S is probably a substrate of breast cancer resistance protein, OATP2B1, and OATP1B3. We also demonstrated sinusoidal and canalicular efflux of both conjugates using sandwich-cultured human hepatocytes. Given substantial expression of these transporters in liver hepatocytes and intestinal enterocytes, this study demonstrates for the first time that transporters could play important roles in the enterohepatic circulation of 25OHD3 conjugates, providing an alternative pathway of 25OHD3 delivery to the intestinal tract, which could be critical for vitamin D receptor-dependent gene regulation in enterocytes. PMID- 29467215 TI - Identification of Intestinal UDP-Glucuronosyltransferase Inhibitors in Green Tea (Camellia sinensis) Using a Biochemometric Approach: Application to Raloxifene as a Test Drug via In Vitro to In Vivo Extrapolation. AB - Green tea (Camellia sinensis) is a popular beverage worldwide, raising concern for adverse interactions when co-consumed with conventional drugs. Like many botanical natural products, green tea contains numerous polyphenolic constituents that undergo extensive glucuronidation. As such, the UDP-glucuronosyltransferases (UGTs), particularly intestinal UGTs, represent potential first-pass targets for green tea-drug interactions. Candidate intestinal UGT inhibitors were identified using a biochemometrics approach, which combines bioassay and chemometric data. Extracts and fractions prepared from four widely consumed teas were screened (20 180 MUg/ml) as inhibitors of UGT activity (4-methylumbelliferone glucuronidation) in human intestinal microsomes; all demonstrated concentration-dependent inhibition. A biochemometrics-identified fraction rich in UGT inhibitors from a representative tea was purified further and subjected to second-stage biochemometric analysis. Five catechins were identified as major constituents in the bioactive subfractions and prioritized for further evaluation. Of these catechins, (-)-epicatechin gallate and (-)-epigallocatechin gallate showed concentration-dependent inhibition, with IC50 values (105 and 59 MUM, respectively) near or below concentrations measured in a cup (240 ml) of tea (66 and 240 MUM, respectively). Using the clinical intestinal UGT substrate raloxifene, the Ki values were ~1.0 and 2.0 MUM, respectively. Using estimated intestinal lumen and enterocyte inhibitor concentrations, a mechanistic static model predicted green tea to increase the raloxifene plasma area under the curve up to 6.1- and 1.3-fold, respectively. Application of this novel approach, which combines biochemometrics with in vitro-in vivo extrapolation, to other natural product-drug combinations will refine these procedures, informing the need for further evaluation via dynamic modeling and clinical testing. PMID- 29467216 TI - Molecular basis for sterol transport by StART-like lipid transfer domains. AB - Lipid transport proteins at membrane contact sites, where two organelles are closely apposed, play key roles in trafficking lipids between cellular compartments while distinct membrane compositions for each organelle are maintained. Understanding the mechanisms underlying non-vesicular lipid trafficking requires characterization of the lipid transporters residing at contact sites. Here, we show that the mammalian proteins in the lipid transfer proteins anchored at a membrane contact site (LAM) family, called GRAMD1a-c, transfer sterols with similar efficiency as the yeast orthologues, which have known roles in sterol transport. Moreover, we have determined the structure of a lipid transfer domain of the yeast LAM protein Ysp2p, both in its apo-bound and sterol-bound forms, at 2.0 A resolution. It folds into a truncated version of the steroidogenic acute regulatory protein-related lipid transfer (StART) domain, resembling a lidded cup in overall shape. Ergosterol binds within the cup, with its 3-hydroxy group interacting with protein indirectly via a water network at the cup bottom. This ligand binding mode likely is conserved for the other LAM proteins and for StART domains transferring sterols.

PMID- 29467217 TI - HP1alpha targets the chromosomal passenger complex for activation at heterochromatin before mitotic entry. AB - The chromosomal passenger complex (CPC) is directed to centromeres during mitosis via binding to H3T3ph and Sgo1. Whether and how heterochromatin protein 1alpha (HP1alpha) influences CPC localisation and function during mitotic entry is less clear. Here, we alter HP1alpha dynamics by fusing it to a CENP-B DNA-binding domain. Tethered HP1 strongly recruits the CPC, destabilising kinetochore microtubule interactions and activating the spindle assembly checkpoint. During mitotic exit, the tethered HP1 traps active CPC at centromeres. These HP1-CPC clusters remain catalytically active throughout the subsequent cell cycle. We also detect interactions between endogenous HP1 and the CPC during G2 HP1alpha and HP1gamma cooperate to recruit the CPC to active foci in a CDK1-independent process. Live cell tracking with Fab fragments reveals that H3S10ph appears well before H3T3 is phosphorylated by Haspin kinase. Our results suggest that HP1 may concentrate and activate the CPC at centromeric heterochromatin in G2 before Aurora B-mediated phosphorylation of H3S10 releases HP1 from chromatin and allows pathways dependent on H3T3ph and Sgo1 to redirect the CPC to mitotic centromeres.

Metaplasia inducing injury caused both gastric chief and pancreatic acinar cells to decrease mTORC1 activity and massively upregulate lysosomes/autophagosomes; then increase damage associated metaplastic genes such as Sox9; and finally reactivate mTORC1 and re-enter the cell cycle. Blocking mTORC1 permitted autophagy and metaplastic gene induction but blocked cell cycle re-entry at S-phase. In kidney and liver regeneration and in human gastric metaplasia, mTORC1 also correlated with proliferation. In lysosome-defective Gnptab-/- mice, both metaplasia-associated gene expression changes and mTORC1-mediated proliferation were deficient in pancreas and stomach. Our findings indicate differentiated cells become proliferative using a sequential program with intervening checkpoints: (i) differentiated cell structure degradation; (ii) metaplasia- or progenitor associated gene induction; (iii) cell cycle re-entry. We propose this program, which we term "paligenosis", is a fundamental process, like apoptosis, available to differentiated cells to fuel regeneration following injury.

PMID- 29467221 TI - Vascular Development. AB - The vascular system forms as a branching network of endothelial cells that acquire identity as arterial, venous, hemogenic, or lymphatic. Endothelial specification depends on gene targets transcribed by Ets domain-containing factors, including Ets variant gene 2 (Etv2), together with the activity of chromatin-remodeling complexes containing Brahma-related gene-1 (Brg1). Once specified and assembled into vessels, mechanisms regulating lumen diameter and axial growth ensure that the structure of the branching vascular network matches the need for perfusion of target tissues. In addition, blood vessels provide important morphogenic cues that guide or direct the development of organs forming around them. As the embryo grows and lumen diameters increase, smooth muscle cells wrap around the nascent vessel walls to provide mechanical strength and vasomotor control of the circulation. Increasing mechanical stretch and wall strain promote smooth muscle cell differentiation via coupling of actin cytoskeletal remodeling to myocardin and serum response factor-dependent transcription. Remodeling of artery walls by developmental signaling pathways reappears in postnatal blood vessels during physiological and pathological adaptation to vessel wall injury, inflammation, or chronic hypoxia. Recent reports providing insights into major steps in vascular development are reviewed here with a particular emphasis on studies that have been recently published in Arteriosclerosis, Thrombosis, and Vascular Biology.

AB - Autophagy is a highly conserved, tightly regulated cellular process that degrades intracellular constituents via lysosomes. Autophagy mediates many normal cellular functions and is dysregulated in numerous diseases. This Thematic Series consists of five Minireviews that highlight selected topics of current autophagy research ranging from the molecular mechanisms and regulation of autophagy to the roles of autophagy in health and disease. PMID- 29467225 TI - The transmembrane protein TMEPAI induces myeloma cell apoptosis by promoting degradation of the c-Maf transcription factor. AB - TMEPAI (transmembrane prostate androgen-induced protein, also called prostate transmembrane protein, androgen-induced 1 (PMEPA1)) is a type I transmembrane (TM) protein, but its cellular function is largely unknown. Here, studying factors influencing the stability of c-Maf, a critical transcription factor in multiple myeloma (MM), we found that TMEPAI induced c-Maf degradation. We observed that TMEPAI recruited NEDD4 (neural precursor cell expressed, developmentally down-regulated 4), a WW domain-containing ubiquitin ligase, to c Maf, leading to its degradation through the proteasomal pathway. Further investigation revealed that TMEPAI interacts with NEDD4 via its conserved PY motifs. Alanine substitution or deletion of these motifs abrogated the TMEPAI complex formation with NEDD4, resulting in failed c-Maf degradation. Functionally, TMEPAI suppressed the transcriptional activity of c-Maf. Of note, increased TMEPAI expression was positively associated with the overall survival of MM patients. Moreover, TMEPAI was down-regulated in MM cells, and re expression of TMEPAI induced MM cell apoptosis. In conclusion, this study highlights that TMEPAI decreases c-Maf stability by recruiting the ubiquitin ligase NEDD4 to c-Maf for proteasomal degradation. Our findings suggest that the restoration of functional TMEPA1 expression may represent a promising complementary therapeutic strategy for treating patients with MM. PMID- 29467226 TI - E4BP4/NFIL3 modulates the epigenetically repressed RAS effector RASSF8 function through histone methyltransferases. AB - RAS proteins are major human oncogenes, and most of the studies are focused on enzymatic RAS effectors. Recently, nonenzymatic RAS effectors (RASSF, RAS association domain family) have garnered special attention because of their tumor suppressive properties in contrast to the oncogenic potential of the classical enzymatic RAS effectors. Whereas most members of RASSF family are deregulated by promoter hypermethylation, RASSF8 promoter remains unmethylated in many cancers but the mechanism(s) of its down-regulation remains unknown. Here, we unveil E4BP4 as a critical transcriptional modulator repressing RASSF8 expression through histone methyltransferases, G9a and SUV39H1. In line with these observations, we noticed a negative correlation of RASSF8 and E4BP4 expression in primary breast tumor samples. In addition, our data provide evidence that E4BP4 attenuates RASSF8-mediated anti-proliferation and apoptosis, shedding mechanistic insights into RASSF8 down-regulation in breast cancers. Collectively, our study provides a better understanding on the epigenetic regulation of RASSF8 function and implicates the development of better treatment strategies. PMID- 29467228 TI - Brain cytoplasmic RNA 1 suppresses smooth muscle differentiation and vascular development in mice. AB - The cardiovascular system develops during the early stages of embryogenesis, and differentiation of smooth muscle cells (SMCs) is essential for that process. SMC differentiation is critically regulated by transforming growth factor (TGF) beta/SMAD family member 3 (SMAD3) signaling, but other regulators may also play a role. For example, long noncoding RNAs (lncRNAs) regulate various cellular activities and events, such as proliferation, differentiation, and apoptosis. However, whether long noncoding RNAs also regulate SMC differentiation remains largely unknown. Here, using the murine cell line C3H10T1/2, we found that brain cytoplasmic RNA 1 (BC1) is an important regulator of SMC differentiation. BC1 overexpression suppressed, whereas BC1 knockdown promoted, TGF-beta-induced SMC differentiation, as indicated by altered cell morphology and expression of multiple SMC markers, including smooth muscle alpha-actin (alphaSMA), calponin, and smooth muscle 22alpha (SM22alpha). BC1 appeared to block SMAD3 activity and inhibit SMC marker gene transcription. Mechanistically, BC1 bound to SMAD3 via RNA SMAD-binding elements (rSBEs) and thus impeded TGF-beta-induced SMAD3 translocation to the nucleus. This prevented SMAD3 from binding to SBEs in SMC marker gene promoters, an essential event in SMC marker transcription. In vivo, BC1 overexpression in mouse embryos impaired vascular SMC differentiation, leading to structural defects in the artery wall, such as random breaks in the elastic lamina, abnormal collagen deposition on SM fibers, and disorganized extracellular matrix proteins in the media of the neonatal aorta. Our results suggest that BC1 is a suppressor of SMC differentiation during vascular development. PMID- 29467229 TI - MANAGEMENT OF ENDOCRINE DISEASE: Can we cure Cushing's disease? A personal view. AB - One of today's challenges in endocrinology is the treatment of Cushing's disease: Although pituitary surgery has the potential to 'cure' the patient and restore a completely normal pituitary adrenal axis, there are immediate failures and late recurrences that will ultimately require alternate therapeutic approaches. Their high number is in direct correlation with their serious limitations and they all appear to be 'default options'. This 'personal view' tries to shed some light on the inescapable difficulties of the current treatments of Cushing's disease and to provide some optimistic view for the future where the pituitary adenoma should be the 'reasonable obsession' of a successful therapeutist. PMID- 29467227 TI - Phosphorylation of CDC25C by AMP-activated protein kinase mediates a metabolic checkpoint during cell-cycle G2/M-phase transition. AB - From unicellular to multicellular organisms, cell-cycle progression is tightly coupled to biosynthetic and bioenergetic demands. Accumulating evidence has demonstrated the G1/S-phase transition as a key checkpoint where cells respond to their metabolic status and commit to replicating the genome. However, the mechanism underlying the coordination of metabolism and the G2/M-phase transition in mammalian cells remains unclear. Here, we show that the activation of AMP activated protein kinase (AMPK), a highly conserved cellular energy sensor, significantly delays mitosis entry. The cell-cycle G2/M-phase transition is controlled by mitotic cyclin-dependent kinase complex (CDC2-cyclin B), which is inactivated by WEE1 family protein kinases and activated by the opposing phosphatase CDC25C. AMPK directly phosphorylates CDC25C on serine 216, a well conserved inhibitory phosphorylation event, which has been shown to mediate DNA damage-induced G2-phase arrest. The acute induction of CDC25C or suppression of WEE1 partially restores mitosis entry in the context of AMPK activation. These findings suggest that AMPK-dependent phosphorylation of CDC25C orchestrates a metabolic checkpoint for the cell-cycle G2/M-phase transition. PMID- 29467230 TI - Unenhanced CT imaging is highly sensitive to exclude pheochromocytoma: a multicenter study. AB - BACKGROUND: A substantial proportion of all pheochromocytomas is currently detected during the evaluation of an adrenal incidentaloma. Recently, it has been suggested that biochemical testing to rule out pheochromocytoma is unnecessary in case of an adrenal incidentaloma with an unenhanced attenuation value <=10 Hounsfield Units (HU) at computed tomography (CT). OBJECTIVES: We aimed to determine the sensitivity of the 10 HU threshold value to exclude a pheochromocytoma. METHODS: Retrospective multicenter study with systematic reassessment of preoperative unenhanced CT scans performed in patients in whom a histopathologically proven pheochromocytoma had been diagnosed. Unenhanced attenuation values were determined independently by two experienced radiologists. Sensitivity of the 10 HU threshold was calculated, and interobserver consistency was assessed using the intraclass correlation coefficient (ICC). RESULTS: 214 patients were identified harboring a total number of 222 pheochromocytomas. Maximum tumor diameter was 51 (39-74) mm. The mean attenuation value within the region of interest was 36 +/- 10 HU. Only one pheochromocytoma demonstrated an attenuation value <=10 HU, resulting in a sensitivity of 99.6% (95% CI: 97.5 99.9). ICC was 0.81 (95% CI: 0.75-0.86) with a standard error of measurement of 7.3 HU between observers. CONCLUSION: The likelihood of a pheochromocytoma with an unenhanced attenuation value <=10 HU on CT is very low. The interobserver consistency in attenuation measurement is excellent. Our study supports the recommendation that in patients with an adrenal incidentaloma biochemical testing for ruling out pheochromocytoma is only indicated in adrenal tumors with an unenhanced attenuation value >10 HU. PMID- 29467231 TI - Diagnostic accuracy of computed tomography to identify adenomas among adrenal incidentalomas in an endocrinological population. AB - CONTEXT: The recent recommendations of the European Endocrine Society states that the performance of computed tomography (CT) to characterize 'true' adrenal incidentalomas (AIs) remains debatable. OBJECTIVE: To determine relevant thresholds for usual CT parameters for the diagnosis of benign tumors using robust reference standard among a large series of 'true' AIs recruited in an endocrinological setting. DESIGN: Retrospective study of 253 AIs in 233 consecutive patients explored in a single university hospital: 183 adenomas, 33 pheochromocytomas, 23 adrenocortical carcinomas, 5 other malignant tumors and 9 other benign tumors. Reference standard was histopathology in 118 AIs, biological diagnosis of pheochromocytoma in 2 AIs and size stability after at least 1 year of follow-up in 133 AIs. METHODS: Sensitivity, specificity and positive and negative predictive values were estimated for various thresholds of size, unenhanced attenuation (UA), relative and absolute wash-out (RPW, APW) of contrast media. 197 scans were reviewed independently in a blinded fashion by two expert radiologists to assess inter-observer reproducibility of measurements. RESULTS: Criteria associated with a 100% positive predictive value for the diagnosis of benign AI were: a combination of size and UA: 30 mm and 20 HU or 40 mm and 15 HU, respectively; RPW >53%; and APW >78%. Non-adenomatous AIs with rapid contrast wash-out were exclusively benign pseudocysts and pheochromocytomas, suggesting that classical thresholds of 60% and 40% for APW and RPW, respectively, can be safely used for patients with normal metanephrine values. Inter-observer reproducibility of all parameters was excellent (intra class correlation coefficients: 0.96-0.99). CONCLUSIONS: Our study, the largest conducted in AIs recruited in an endocrinological setting, suggests safe thresholds for quantitative CT parameters to avoid false diagnoses of benignity. PMID- 29467232 TI - Deletion in the uridine diphosphate glucuronyltransferase 2B17 gene is associated with delayed pubarche in healthy boys. AB - OBJECTIVE: Only a few genetic loci are known to be associated with male pubertal events. The ability of excreting testosterone (T) and other steroids in the urine depends on sulfation and glucuronidation. One of several essential glucuronidases is encoded by the UGT2B17 gene. In a preliminary report, we found that homozygous deletion of UGT2B17 in boys was associated with lower urinary excretion of T. We hypothesized that boys with a lower glucuronidation capacity may have altered androgen action and excretion affecting pubarche, as this represents a T dependent event. DESIGN, PARTICIPANTS AND MEASURES: 668 healthy boys (cross sectional) aged 6.1-21.9 years (COPENHAGEN puberty study conducted from 2005 to 2006) were included. 65 of the boys where followed longitudinally every 6 months. Participants were genotyped for UGT2B17 copy number variation (CNV). Clinical pubertal staging including orchidometry, anthropometry and serum reproductive hormone levels. RESULTS: 59 of the 668 boys (8.8%) presented with a homozygous deletion of UGT2B17 (del/del). These boys experienced pubarche at a mean age of 12.73 years (12.00-13.46) vs 12.40 years (12.11-12.68) in boys heterozygous for deletion of UGT2B17 (del/ins) vs 12.06 years (11.79-12.33) in boys with the wild type genotype (ins/ins) (P = 0.029, corrected for BMI z-score). The effect accounted for 0.34 years delay per allele (95% CI: 0.03-0.64). A comparable trend was observed for onset of testicular enlargement >3 mL but did not reach significance. CONCLUSION: CNV of UGT2B17 is a factor contributing to the timing of male pubarche.

PMID- 29467233 TI - Validating upstream regulators of Yorkie activity in Hippo signaling through scalloped-based genetic epistasis. AB - Genetic studies in Drosophila have been instrumental in characterizing the Hippo pathway, which converges on the co-activator Yorkie to regulate target gene transcription. A routinely used strategy to interrogate upstream regulators of Yorkie involves the examination of selected Hippo target genes upon loss or gain of function of a suspected pathway regulator. A caveat with this strategy is that aberrant expression of a given Hippo target per se does not distinguish whether it is caused by changes in Yorkie or Yorkie-independent inputs converging on the same target gene. Building on previous findings that the DNA-binding transcription factor Scalloped mediates both Yorkie overexpression and loss-of function phenotypes yet is itself dispensable for normal eye development, we describe a simple strategy to distinguish these possibilities by analyzing double mutant clones of scalloped and a suspected Yorkie regulator. We provide proof of principle that this strategy can be used effectively to validate canonical Yorkie regulators and to exclude proteins that impact target expression independent of Yorkie. The described methodology and reagents should facilitate efforts to assess the expanding repertoire of proteins implicated in regulation of Yorkie activity.

The E&E provides a rationale for each item and includes examples for how each item has been reported in published papers evaluating patient decision aids. The E&E focuses on items key to reporting studies evaluating patient decision aids and is intended to be illustrative rather than restrictive. Authors and reviewers may wish to use the E&E broadly to inform structuring of patient decision aid evaluation reports, or use it as a reference to obtain details about how to report individual checklist items. PMID- 29467236 TI - Hematopoietic stem cells from induced pluripotent stem cells - considering the role of microRNA as a cell differentiation regulator. AB - Although hematopoietic stem cell (HSC) therapy for hematological diseases can lead to a good outcome from the clinical point of view, the limited number of ideal donors, the comorbidity of patients and the increasing number of elderly patients may limit the application of this therapy. HSCs can be generated from induced pluripotent stem cells (iPSCs), which requires the understanding of the bone marrow and liver niches components and function in vivo iPSCs have been extensively applied in several studies involving disease models, drug screening and cellular replacement therapies. However, the somatic reprogramming by transcription factors is a low-efficiency process. Moreover, the reprogramming process is also regulated by microRNAs (miRNAs), which modulate the expression of the transcription factors OCT-4 (also known as POU5F1), SOX-2, KLF-4 and MYC, leading somatic cells to a pluripotent state. In this Review, we present an overview of the challenges of cell reprogramming protocols with regard to HSC generation from iPSCs, and highlight the potential role of miRNAs in cell reprogramming and in the differentiation of induced pluripotent stem cells.

PMID- 29467238 TI - Ethanol Reversal of Oxycodone Tolerance in Dorsal Root Ganglia Neurons. AB - Oxycodone is a semisynthetic opioid compound that is widely prescribed, used, and abused today, and has a well-established role in shaping the current opioid epidemic. Previously, we have shown that tolerance develops to the antinociceptive and respiratory depressive effects of oxycodone in mice, and that a moderate dose of acute ethanol or a protein kinase C (PKC) inhibitor reversed that tolerance. To investigate further if tolerance was occurring through neuronal mechanisms, our aims for this study were to assess the effects of acute and prolonged oxycodone in isolated dorsal root ganglia (DRG) neurons and to determine if this tolerance was reversed by either ethanol or a PKC inhibitor. We found that an acute exposure to 3 MUM oxycodone reduced neuronal excitability, as measured by increased threshold potentials and reduced action potential amplitude, without eliciting measurable changes in resting membrane potential. Exposure to 10 MUM oxycodone for 18-24 hours prevented oxycodone's effect on neuronal excitability, indicative of tolerance development. The development of opioid tolerance was mitigated in DRG neurons from beta-arrestin 2 knockout mice. Oxycodone tolerance was reversed in isolated DRG neurons by the acute application of either ethanol (20 mM) or the PKC inhibitor, bisindolylmaleimide XI hydrochloride (Bis XI), when a challenge of 3 uM oxycodone significantly reduced neuronal excitability following prolonged exposure. Through these studies, we concluded that oxycodone acutely reduced neuronal excitability, tolerance developed to this effect, and reversal of that tolerance occurred at the level of a single neuron, suggesting that reversal of oxycodone tolerance by either ethanol or Bis XI involves cellular mechanisms.

AB - Bacteria are crucial partners in the development and evolution of vertebrates and invertebrates. A large fraction of insects harbor Wolbachia, bacterial endosymbionts that manipulate host reproduction to favor their spreading. Because they are maternally inherited, Wolbachia are under selective pressure to reach the female germline and infect the offspring. However, Wolbachia infection is not limited to the germline. Somatic cell types, including stem cell niches, have higher Wolbachia loads compared with the surrounding tissue. Here, we show a novel Wolbachia tropism to polar cells (PCs), specialized somatic cells in the Drosophila ovary. During oogenesis, all stages of PC development are easily visualized, facilitating the investigation of the kinetics of Wolbachia intracellular growth. Wolbachia accumulation is triggered by particular events of PC morphogenesis, including differentiation from progenitors and between stages 8 and 9 of oogenesis. Moreover, induction of ectopic PC fate is sufficient to promote Wolbachia accumulation. We found that Wolbachia PC tropism is evolutionarily conserved across most Drosophila species, but not in Culex mosquitos. These findings highlight the coordination of endosymbiont tropism with host development and cell differentiation. PMID- 29467240 TI - Identification, isolation and characterization of human LGR5-positive colon adenoma cells. AB - The intestine is maintained by stem cells located at the base of crypts and distinguished by the expression of LGR5. Genetically engineered mouse models have provided a wealth of information about intestinal stem cells, whereas less is known about human intestinal stem cells owing to difficulty detecting and isolating these cells. We established an organoid repository from patient-derived adenomas, adenocarcinomas and normal colon, which we analyzed for variants in 71 colorectal cancer (CRC)-associated genes. Normal and neoplastic colon tissue organoids were analyzed by immunohistochemistry and fluorescent-activated cell sorting for LGR5. LGR5-positive cells were isolated from four adenoma organoid lines and were subjected to RNA sequencing. We found that LGR5 expression in the epithelium and stroma was associated with tumor stage, and by integrating functional experiments with LGR5-sorted cell RNA sequencing data from adenoma and normal organoids, we found correlations between LGR5 and CRC-specific genes, including dickkopf WNT signaling pathway inhibitor 4 (DKK4) and SPARC-related modular calcium binding 2 (SMOC2). Collectively, this work provides resources, methods and new markers to isolate and study stem cells in human tissue homeostasis and carcinogenesis. PMID- 29467243 TI - Hormonal control of growth in the wing imaginal disks of Junonia coenia: the relative contributions of insulin and ecdysone. AB - The wing imaginal disks of Lepidoptera can be grown in tissue culture, but require both insulin and ecdysone to grow normally. Here, we investigate the contributions the two hormones make to growth. Ecdysone is required to maintain mitoses, whereas in the presence of insulin alone mitoses stop. Both ecdysone and insulin stimulate protein synthesis, but only ecdysone stimulates DNA synthesis. Insulin stimulates primarily cytoplasmic growth and an increase in cell size, whereas ecdysone, by virtue of its stimulation of DNA synthesis and mitosis, stimulates growth by an increase in cell number. Although both hormones stimulate protein synthesis, they do so in different spatial patterns. Both hormones stimulate protein synthesis in the inter-vein regions, but ecdysone stimulates synthesis more strongly in the veins and in the margin of the wing disk. We propose that the balance of insulin and ecdysone signaling must be regulated to maintain normal growth, and when growth appears to be due primarily to an increase in cell number, or an increase in cell size, this may indicate growth occurred under conditions that favored a stronger role for ecdysone, or insulin, respectively. PMID- 29467242 TI - Prothoracicotropic hormone modulates environmental adaptive plasticity through the control of developmental timing. AB - Adult size and fitness are controlled by a combination of genetics and environmental cues. In Drosophila, growth is confined to the larval phase and final body size is impacted by the duration of this phase, which is under neuroendocrine control. The neuropeptide prothoracicotropic hormone (PTTH) has been proposed to play a central role in controlling the length of the larval phase through regulation of ecdysone production, a steroid hormone that initiates larval molting and metamorphosis. Here, we test this by examining the consequences of null mutations in the Ptth gene for Drosophila development. Loss of Ptth causes several developmental defects, including a delay in developmental timing, increase in critical weight, loss of coordination between body and imaginal disc growth, and reduced adult survival in suboptimal environmental conditions such as nutritional deprivation or high population density. These defects are caused by a decrease in ecdysone production associated with altered transcription of ecdysone biosynthetic genes. Therefore, the PTTH signal contributes to coordination between environmental cues and the developmental program to ensure individual fitness and survival. PMID- 29467244 TI - Precise spatial restriction of BMP signaling in developing joints is perturbed upon loss of embryo movement. AB - Dynamic mechanical loading of synovial joints is necessary for normal joint development, as evidenced in certain clinical conditions, congenital disorders and animal models where dynamic muscle contractions are reduced or absent. Although the importance of mechanical forces on joint development is unequivocal, little is known about the molecular mechanisms involved. Here, using chick and mouse embryos, we observed that molecular changes in expression of multiple genes analyzed in the absence of mechanical stimulation are consistent across species. Our results suggest that abnormal joint development in immobilized embryos involves inappropriate regulation of Wnt and BMP signaling during definition of the emerging joint territories, i.e. reduced beta-catenin activation and concomitant upregulation of pSMAD1/5/8 signaling. Moreover, dynamic mechanical loading of the developing knee joint activates Smurf1 expression; our data suggest that Smurf1 insulates the joint region from pSMAD1/5/8 signaling and is essential for maintenance of joint progenitor cell fate. PMID- 29467245 TI - Lineage- and stage-specific expressed CYCD7;1 coordinates the single symmetric division that creates stomatal guard cells. AB - Plants, with cells fixed in place by rigid walls, often utilize spatial and temporally distinct cell division programs to organize and maintain organs. This leads to the question of how developmental regulators interact with the cell cycle machinery to link cell division events with particular developmental trajectories. In Arabidopsis leaves, the development of stomata, two-celled epidermal valves that mediate plant-atmosphere gas exchange, relies on a series of oriented stem cell-like asymmetric divisions followed by a single symmetric division. The stomatal lineage is embedded in a tissue in which other cells transition from proliferation to postmitotic differentiation earlier, necessitating stomatal lineage-specific factors to prolong competence to divide. We show that the D-type cyclin, CYCD7;1, is specifically expressed just prior to the symmetric guard cell-forming division, and that it is limiting for this division. Further, we find that CYCD7;1 is capable of promoting divisions in multiple contexts, likely through RBR1-dependent promotion of the G1/S transition, but that CYCD7;1 is regulated at the transcriptional level by cell type-specific transcription factors that confine its expression to the appropriate developmental window. PMID- 29467246 TI - The transcriptome of early chicken embryos reveals signaling pathways governing rapid asymmetric cellularization and lineage segregation. AB - The phylogenomics and comparative functional genomics of avian species were investigated in the Bird 10,000 Genomes (B10K) project because of the important evolutionary position of birds and their value as a research model. However, the systematic profiling of transcriptional changes prior to oviposition has not been investigated in avian species because of the practical difficulties in obtaining pre-oviposited eggs. In this study, a total of 137 pre-oviposited embryos were collected from hen ovaries and oviducts and subjected to RNA-sequencing analyses. Two waves of chicken zygotic genome activation (ZGA) were observed. Functionally distinct developmental programs involving Notch, MAPK, Wnt and TGFbeta signaling were separately detected during cleavage and area pellucida formation. Furthermore, the early stages of chicken development were compared with the human and mouse counterparts, highlighting chicken-specific signaling pathways and gradually analogous gene expression via ZGA. These findings provide a genome-wide understanding of avian embryogenesis and comparisons among amniotes. PMID- 29467247 TI - Fat body glycogen serves as a metabolic safeguard for the maintenance of sugar levels in Drosophila. AB - Adapting to changes in food availability is a central challenge for survival. Glucose is an important resource for energy production, and therefore many organisms synthesize and retain sugar storage molecules. In insects, glucose is stored in two different forms: the disaccharide trehalose and the branched polymer glycogen. Glycogen is synthesized and stored in several tissues, including in muscle and the fat body. Despite the major role of the fat body as a center for energy metabolism, the importance of its glycogen content remains unclear. Here, we show that glycogen metabolism is regulated in a tissue-specific manner under starvation conditions in the fruit fly Drosophila The mobilization of fat body glycogen in larvae is independent of Adipokinetic hormone (Akh, the glucagon homolog) but is regulated by sugar availability in a tissue-autonomous manner. Fat body glycogen plays a crucial role in the maintenance of circulating sugars, including trehalose, under fasting conditions. These results demonstrate the importance of fat body glycogen as a metabolic safeguard in Drosophila. PMID- 29467249 TI - RNA tales - how embryos read and discard messages from mom. AB - Following fertilization, embryos develop for a substantial amount of time with a transcriptionally silent genome. Thus, early development is maternally programmed, as it solely relies on RNAs and proteins that are provided by the female gamete. However, these maternal instructions are not sufficient to support later steps of embryogenesis and are therefore gradually replaced by novel products synthesized from the zygotic genome. This switch in the origin of molecular players that drive early development is known as the maternal-to zygotic transition (MZT). MZT is a universal phenomenon among all metazoans and comprises two interconnected processes: maternal mRNA degradation and the transcriptional awakening of the zygotic genome. The recent adaptation of high throughput methods for use in embryos has deepened our knowledge of the molecular principles underlying MZT. These mechanisms comprise conserved strategies for RNA regulation that operate in many well-studied cellular contexts but that have adapted differently to early development. In this Review, we will discuss advances in our understanding of post-transcriptional regulatory pathways that drive maternal mRNA clearance during MZT, with an emphasis on recent data in zebrafish embryos on codon-mediated mRNA decay, the contributions of microRNAs (miRNAs) and RNA-binding proteins to this process, and the roles of RNA modifications in the stability control of maternal mRNAs. PMID- 29467248 TI - alpha-Catenin-dependent cytoskeletal tension controls Yap activity in the heart. AB - Shortly after birth, muscle cells of the mammalian heart lose their ability to divide. At the same time, the N-cadherin/catenin cell adhesion complex accumulates at the cell termini, creating a specialized type of cell-cell contact called the intercalated disc (ICD). To investigate the relationship between ICD maturation and proliferation, alphaE-catenin (Ctnna1) and alphaT-catenin (Ctnna3) genes were deleted to generate cardiac-specific alpha-catenin double knockout (DKO) mice. DKO mice exhibited aberrant N-cadherin expression, mislocalized actomyosin activity and increased cardiomyocyte proliferation that was dependent on Yap activity. To assess effects on tension, cardiomyocytes were cultured on deformable polyacrylamide hydrogels of varying stiffness. When grown on a stiff substrate, DKO cardiomyocytes exhibited increased cell spreading, nuclear Yap and proliferation. A low dose of either a myosin or RhoA inhibitor was sufficient to block Yap accumulation in the nucleus. Finally, activation of RhoA was sufficient to increase nuclear Yap in wild-type cardiomyocytes. These data demonstrate that alpha-catenins regulate ICD maturation and actomyosin contractility, which, in turn, control Yap subcellular localization, thus providing an explanation for the loss of proliferative capacity in the newborn mammalian heart.

Aim21/Tda2 also interacts with Cap1/Cap2, revealing a complex interplay between actin assembly regulators. PMID- 29467253 TI - Membrane detachment is not essential for COG complex function. AB - COG is a multisubunit vesicle tethering complex in the Golgi. We demonstrate that both COG subcomplexes can be permanently attached to Golgi membranes and that major COG functions do not require cycling between the membrane and cytosol.

AB - We show that BDNF regulates the timing of neurodevelopment via a novel mechanism of extranuclear sequestration of NFATc4 in Golgi. This leads to accelerated derepression of an NFI temporal occupancy gene program in cerebellar granule cells that includes Bdnf itself, revealing an autoregulatory loop within the program driven by BDNF and NFATc4. PMID- 29467255 TI - Altered translation initiation of Gja1 limits gap junction formation during epithelial-mesenchymal transition. AB - Epithelial-mesenchymal transition (EMT) is activated during development, wound healing, and pathologies including fibrosis and cancer metastasis. Hallmarks of EMT are remodeling of intercellular junctions and adhesion proteins, including gap junctions. The GJA1 mRNA transcript encoding the gap junction protein connexin43 (Cx43) has been demonstrated to undergo internal translation initiation, yielding truncated isoforms that modulate gap junctions. The PI3K/Akt/mTOR pathway is central to translation regulation and is activated during EMT, leading us to hypothesize that altered translation initiation would contribute to gap junction loss. Using TGF-beta-induced EMT as a model, we find reductions in Cx43 gap junctions despite increased transcription and stabilization of Cx43 protein. Biochemical experiments reveal suppression of the internally translated Cx43 isoform, GJA1-20k in a Smad3 and ERK-dependent manner. Ectopic expression of GJA1-20k does not halt EMT, but is sufficient to rescue gap junction formation. GJA1-20k localizes to the Golgi apparatus, and using super resolution localization we find retention of GJA1-43k at the Golgi in mesenchymal cells lacking GJA1-20k. NativePAGE reveals that levels of GJA1-20k regulate GJA1 43k hexamer oligomerization, a limiting step in Cx43 trafficking. These findings reveal alterations in translation initiation as an unexplored mechanism by which the cell regulates Cx43 gap junction formation during EMT. PMID- 29467256 TI - Commonly used trafficking blocks disrupt ARF1 activation and the localization and function of specific Golgi proteins. AB - Cold temperature blocks used to synchronize protein trafficking inhibit GBF1 function, leading to a decrease in ARF1-GTP levels and mislocalization of the ARF1 effector golgin-160. Several other, but not all, Golgi proteins including ARL1 also mislocalize. ARF1 activity and golgin-160 localization require more than 30 min to recover from these blocks. PMID- 29467257 TI - Product diffusion through on-demand information-seeking behaviour. AB - Most models of product adoption predict S-shaped adoption curves. Here we report results from two country-scale experiments in which we find linear adoption curves. We show evidence that the observed linear pattern is the result of active information-seeking behaviour: individuals actively pulling information from several central sources facilitated by modern Internet searches. Thus, a constant baseline rate of interest sustains product diffusion, resulting in a linear diffusion process instead of the S-shaped curve of adoption predicted by many diffusion models. The main experiment seeded 70 000 (48 000 in Experiment 2) unique voucher codes for the same product with randomly sampled nodes in a social network of approximately 43 million individuals with about 567 million ties. We find that the experiment reached over 800 000 individuals with 80% of adopters adopting the same product-a winner-take-all dynamic consistent with search engine driven rankings that would not have emerged had the products spread only through a network of social contacts. We provide evidence for (and characterization of) this diffusion process driven by active information-seeking behaviour through analyses investigating (a) patterns of geographical spreading; (b) the branching process; and (c) diffusion heterogeneity. Using data on adopters' geolocation we show that social spreading is highly localized, while on-demand diffusion is geographically independent. We also show that cascades started by individuals who actively pull information from central sources are more effective at spreading the product among their peers.

AB - Tendon experiences a variety of multiscale changes to its extracellular matrix during mechanical loading at the fascicle, fibre and fibril levels. For example, tensile loading of tendon increases its stiffness, with organization of collagen fibres, and increases cell strain in the direction of loading. Although applied macroscale strains correlate to cell and nuclear strains in uninjured tendon, the multiscale response during tendon healing remains unknown and may affect cell mechanosensing and response. Therefore, this study evaluated multiscale structure function mechanisms in response to quasi-static tensile loading in uninjured and healing tendons. We found that tendon healing affected the macroscale mechanical and structural response to mechanical loading, evidenced by decreases in strain stiffening and collagen fibre realignment. At the micro- and nanoscales, healing resulted in increased collagen fibre disorganization, nuclear disorganization, decreased change in nuclear aspect ratio with loading, and decreased indentation modulus compared to uninjured tendons. Taken together, this work supports a new concept of nuclear strain transfer attenuation during tendon healing and identifies several multiscale properties that may contribute. Our work also provides benchmarks for the biomechanical microenvironments that tendon cells may experience following cell delivery therapies. PMID- 29467259 TI - Structural origins of coloration in the spider Phoroncidia rubroargentea Berland, 1913 (Araneae: Theridiidae) from Madagascar. AB - This study investigates the structural basis for the red, silver and black coloration of the theridiid spider, Phoroncidia rubroargentea (Berland, 1913) from Madagascar. Specimens of this species can retain their colour after storage in ethanol for decades, whereas most other brightly pigmented spider specimens fade under identical preservation conditions. Using correlative optical, structural and chemical analysis, we identify the colour-generating structural elements and characterize their optical properties. The prominent silvery appearance of the spider's abdomen results from regularly arranged guanine microplatelets, similar to those found in other spiders and fish. The microplatelets are composed of a doublet structure twinned about the [[Formula: see text]] axis, as suggested by electron diffraction. The red coloration originates from chambered microspheres (approx. 1 um in diameter), which contain structured fluorescent material. Co-localization of the red microparticles on top of the reflective guanine microplatelets appears to enhance the red coloration. The spider's thick cuticular layer, which encases its abdomen, varies in its optical properties, being transparent in regions where only guanine reflectors are present, and tanned, exhibiting light absorption where the red microspheres are found. Moreover, colour degradation in some preserved spider specimens that had suffered damage to the cuticular layer suggests that this region of the exoskeleton may play an important role in the stabilization of the red coloration. PMID- 29467260 TI - Clownfishes evolution below and above the species level. AB - The difference between rapid morphological evolutionary changes observed in populations and the long periods of stasis detected in the fossil record has raised a decade-long debate about the exact role played by intraspecific mechanisms at the interspecific level. Although they represent different scales of the same evolutionary process, micro- and macroevolution are rarely studied together and few empirical studies have compared the rates of evolution and the selective pressures between both scales. Here, we analyse morphological, genetic and ecological traits in clownfishes at different evolutionary scales and demonstrate that the tempo of molecular and morphological evolution at the species level can be, to some extent, predicted from parameters estimated below the species level, such as the effective population size or the rate of evolution within populations. We also show that similar codons in the gene of the rhodopsin RH1, a light-sensitive receptor protein, are under positive selection at the intra and interspecific scales, suggesting that similar selective pressures are acting at both levels. PMID- 29467261 TI - Estimating encounter rates as the first step of sexual selection in the lizard Anolis sagrei. AB - How individuals move through their environment dictates which other individuals they encounter, determining their social and reproductive interactions and the extent to which they experience sexual selection. Specifically, females rarely have the option of mating with all males in a population-they can only choose among the males they encounter. Further, quantifying phenotypic differences between the males that females encounter and those that sire females' offspring lends insight into how social and reproductive interactions shape male phenotypes. We used an explicitly spatio-temporal Markov chain model to estimate the number of potential mates of Anolis sagrei lizards from their movement behaviour, and used genetic paternity assignments to quantify sexual selection on males. Females frequently encountered and mated with multiple males, offering ample opportunity for female mate choice. Sexual selection favoured males that were bigger and moved over larger areas, though the effect of body size cannot be disentangled from last-male precedence. Our approach corroborates some patterns of sexual selection previously hypothesized in anoles based on describing them as territorial, whereas other results, including female multiple mating itself, are at odds with territorial polygyny, offering insight into discrepancies in other taxa between behavioural and genetic descriptions of mating systems. PMID- 29467262 TI - Flight range, fuel load and the impact of climate change on the journeys of migrant birds. AB - Climate change is predicted to increase migration distances for many migratory species, but the physiological and temporal implications of longer migratory journeys have not been explored. Here, we combine information about species' flight range potential and migratory refuelling requirements to simulate the number of stopovers required and the duration of current migratory journeys for 77 bird species breeding in Europe. Using tracking data, we show that our estimates accord with recorded journey times and stopovers for most species. We then combine projections of altered migratory distances under climate change with models of avian flight to predict future migratory journeys. We find that 37% of migratory journeys undertaken by long-distance migrants will necessitate an additional stopover in future. These greater distances and the increased number of stops will substantially increase overall journey durations of many long distance migratory species, a factor not currently considered in climate impact studies.

PMID- 29467264 TI - Macroevolutionary patterning of woodpecker drums reveals how sexual selection elaborates signals under constraint. AB - Sexual selection drives elaboration in animal displays used for competition and courtship, but this process is opposed by morphological constraints on signal design. How do interactions between selection and constraint shape display evolution? One possibility is that sexual selection continues exaggeration under constraint by operating differentially on each signal component in complex, modular displays. This is seldom studied on a phylogenetic scale, but we address the issue herein by studying macroevolutionary patterning of woodpecker drum displays. These territorial displays are produced when an individual rapidly hits its bill on a hard surface, and drums vary across species in the number of beats included (length) and the rate of drumbeat production (speed). We report that species body size limits drum speed, but not drum length. As a result of this biomechanical constraint, there is less standing variation in speed than length. We also uncover a positive relationship between sexual size dimorphism and the unconstrained trait (length), but with no effect on speed. This suggests that when morphology limits the exaggeration of one component, sexual selection instead exaggerates the unconstrained trait. Modular displays therefore provide the basis for selection to find novel routes to phenotypic elaboration after previous ones are closed. PMID- 29467265 TI - apterous A specifies dorsal wing patterns and sexual traits in butterflies. AB - Butterflies have evolved different colour patterns on their dorsal and ventral wing surfaces to serve different signalling functions, yet the developmental mechanisms controlling surface-specific patterning are still unknown. Here, we mutate both copies of the transcription factor apterous in Bicyclus anynana butterflies using CRISPR/Cas9 and show that apterous A, expressed dorsally, functions both as a repressor and modifier of ventral wing colour patterns, as well as a promoter of dorsal sexual ornaments in males. We propose that the surface-specific diversification of wing patterns in butterflies proceeded via the co-option of apterous A or its downstream effectors into various gene regulatory networks involved in the differentiation of discrete wing traits. Further, interactions between apterous and sex-specific factors such as doublesex may have contributed to the origin of sexually dimorphic surface-specific patterns. Finally, we discuss the evolution of eyespot number diversity in the family Nymphalidae within the context of developmental constraints due to apterous regulation. PMID- 29467266 TI - Oldest known multituberculate stapes suggests an asymmetric bicrural pattern as ancestral for Multituberculata. AB - Middle ear ossicles (malleus, incus, stapes) are known for few multituberculate taxa, and three different stapedial morphotypes have been suggested: (i) slender, columelliform and microperforate, (ii) robust and rod-like, and (iii) bicrural. Reinvestigation of Upper Jurassic (Kimmeridgian) mammalian petrosals from the Guimarota coal mine in central Portugal (Western Europe) revealed an asymmetric bicrural stapes (ABS) in the paulchoffatiid Pseudobolodon oreas The middle ear ossicles displaced inside the osseous vestibule were detected by a uCT analysis. The Kimmeridgian age of the Guimarota stapes exceeds the stapes from the Early Cretaceous (Barremian) of Asia (about 122-124 Ma) by approximately 30 Myr, and is only slightly younger than the stapes of the recently described Oxfordian euharamiyidan Arboroharamiya allinhopsoni The Guimarota stapes indicates that the stapes of Lambdopsalis, described as columelliform and microperforate (small stapedial foramen), does not represent a general condition for multituberculates. The stapes of Pseudobolodon is bicrural, the anterior crus sits centrally on the oval footplate, and the stapedial head is simple and smaller than the footplate. We hypothesize that the ABS evolved from the symmetric bicrural stapes (SBS) of non-mammaliaform cynodonts. The ABS appears to be the ancestral morphotype of the mammalian SBS, and the mammalian columelliform imperforate stapes. PMID- 29467267 TI - Pattern and process in hominin brain size evolution are scale-dependent. AB - A large brain is a defining feature of modern humans, yet there is no consensus regarding the patterns, rates and processes involved in hominin brain size evolution. We use a reliable proxy for brain size in fossils, endocranial volume (ECV), to better understand how brain size evolved at both clade- and lineage level scales. For the hominin clade overall, the dominant signal is consistent with a gradual increase in brain size. This gradual trend appears to have been generated primarily by processes operating within hypothesized lineages-64% or 88% depending on whether one uses a more or less speciose taxonomy, respectively. These processes were supplemented by the appearance in the fossil record of larger-brained Homo species and the subsequent disappearance of smaller-brained Australopithecus and Paranthropus taxa. When the estimated rate of within-lineage ECV increase is compared to an exponential model that operationalizes generation scale evolutionary processes, it suggests that the observed data were the result of episodes of directional selection interspersed with periods of stasis and/or drift; all of this occurs on too fine a timescale to be resolved by the current human fossil record, thus producing apparent gradual trends within lineages. Our findings provide a quantitative basis for developing and testing scale-explicit hypotheses about the factors that led brain size to increase during hominin evolution.

The impact of diallelic self-incompatibility on the sexual system in Fraxinus excelsior (Oleaceae). AB - How flowering plants have recurrently evolved from hermaphroditism to separate sexes (dioecy) is a central question in evolutionary biology. Here, we investigate whether diallelic self-incompatibility (DSI) is associated with sexual specialization in the polygamous common ash (Fraxinus excelsior), which would ultimately facilitate the evolution towards dioecy. Using interspecific crosses, we provide evidence of strong relationships between the DSI system and sexual phenotype. The reproductive system in F. excelsior that was previously viewed as polygamy (co-occurrence of unisexuals and hermaphrodites with varying degrees of allocation to the male and female functions) and thus appears to actually behave as a subdioecious system. Hermaphrodites and females belong to one SI group and functionally reproduce as females, whereas males and male-biased hermaphrodites belong to the other SI group and are functionally males. Our results offer an alternative mechanism for the evolution of sexual specialization in flowering plants.

AB - Hepatoma-derived growth factor (HDGF) is a potent mitogen for vascular smooth muscle cells (SMCs) during embryogenesis and injury repair of vessel walls. Whether mechanical stimuli modulate HDGF expression remains unknown. This study aimed at investigating whether cyclic mechanical stretch plays a regulatory role in HDGF expression and regenerative cytokine production in aortic SMCs. A SMC cell line was grown on a silicone-based elastomer chamber with extracellular matrix coatings (either type I collagen or fibronectin) and received cyclic and uni-axial mechanical stretches with 10% deformation at frequency 1 Hz. Morphological observation showed that fibronectin coating provided better cell adhesion and spreading and that consecutive 6 hours of cyclic mechanical stretch remarkably induced reorientation and realignment of SMCs. Western blotting detection demonstrated that continuous mechanical stimuli elicited up-regulation of HDGF and PCNA, a cell proliferative marker. Signal kinetic profiling study indicated that cyclic mechanical stretch induced signaling activity in RhoA/ROCK and PI3K/Akt cascades. Kinase inhibition study further showed that blockade of PI3K activity suppressed the stretch-induced TNF-a, whereas RhoA/ROCK inhibition significantly blunted the IL-6 production and HDGF over-expression. Moreover, siRNA-mediated HDGF gene silencing significantly suppressed constitutive expression of IL-6, but not TNF-alpha, in SMCs. These findings support the role of HDGF in maintaining vascular expression of IL-6, which has been regarded a crucial regenerative factor for acute vascular injury. In conclusion, cyclic mechanical stretch may maintain constitutive expression of HDGF in vascular walls and be regarded an important biophysical regulator in vascular regeneration.

AB - Truncated APC selective inhibitor-1 (TASIN-1) is a recently identified small molecule that selectively kills colorectal cancer cells that express truncated adenomatous polyposis coli (APC) by reducing cellular cholesterol levels. However, the downstream mechanism responsible for its cytotoxicity is not well understood. In this study, we show that TASIN-1 leads to apoptotic cell death via inducing ER stress-dependent JNK activation in human truncated APC colon cancer cells, accompanied by production of reactive oxygen species (ROS). In addition, TASIN-1 inhibits AKT activity through a cholesterol-dependent manner. Human colon tumor xenografts in immunodeficient mice also show the same TASIN-1 induced molecular mechanisms of tumor cell death as observed in vitro Taken together, cholesterol depletion by TASIN-1 treatment induces apoptotic cell death through activating ER stress/ROS/JNK axis and inhibiting AKT pro-survival signaling in colon cancer cells with truncated APC both in vitro and in vivoMol Cancer Ther; 17(5); 943-51.

AB - Lung cancer is the leading cause of cancer-related deaths worldwide. Approximately 85% of all lung cancers are non-small cell histology [non-small cell lung cancer (NSCLC)]. Modern treatment strategies for NSCLC target driver oncogenes and immune checkpoints. However, less than 15% of patients survive beyond 5 years. Here, we investigated the effects of SAR302503 (SAR), a selective JAK2 inhibitor, on NSCLC cell lines and tumors. We show that SAR is cytotoxic to NSCLC cells, which exhibit resistance to genotoxic therapies, such as ionizing radiation, cisplatin, and etoposide. We demonstrate that constitutive IFN stimulated gene expression, including an IFN-related DNA damage resistance signature, predicts for sensitivity to SAR. Importantly, tumor cell-intrinsic expression of PD-L1 is IFN-inducible and abrogated by SAR. Taken together, these findings suggest potential dual roles for JAK2 inhibitors, both as a novel monotherapy in NSCLCs resistant to genotoxic therapies, and in tandem with immune checkpoint inhibition.

AB - Multiple epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (EGFR TKI) have been developed to effectively inhibit EGFR-derived signals in non-small cell lung cancer (NSCLC). In this study, we assessed the efficacy of EGFR-TKIs, including a novel third-generation inhibitor naquotinib (ASP8273), in clinically relevant EGFR mutations, including L858R, exon 19 deletion, L858R+T790M, exon 19 deletion+T790M with or without a C797S mutation, and several exon 20 insertion mutations. Using structural analyses, we also elucidated the mechanism of activation and sensitivity/resistance to EGFR-TKIs in EGFR exon 20 insertion mutations. The efficacy of naquotinib in cells with L858R, exon 19 deletion and exon 19 deletion+T790M was comparable with that of osimertinib. Interestingly, naquotinib was more potent than osimertinib for L858R+T790M. Additionally, naquotinib and osimertinib had comparable efficacy and a wide therapeutic window for cells with EGFR exon 20 insertions. Structural modeling partly elucidated the mechanism of activation and sensitivity/resistance to EGFR-TKIs in two EGFR exon 20 insertion mutants, A767_V769dupASV and Y764_V765insHH. In summary, we have characterized the efficacy of EGFR-TKIs for NSCLC using in vitro and structural analyses and suggested the mechanism of activation and resistance to EGFR-TKIs of EGFR exon 20 insertion mutations. Our findings should guide the selection of appropriate EGFR-TKIs for the treatment of NSCLC with EGFR mutations and help clarify the biology of EGFR exon 20 insertion mutations.

AB - OBJECTIVES: Seattle Children's Hospital sought to optimize the value equation for neonatal jaundice patients by creating a standard care pathway. METHODS: An evidence-based pathway for management of neonatal jaundice was created. This included multidisciplinary team assembly, comprehensive literature review, creation of a treatment algorithm and computer order sets, formulation of goals and metrics, roll-out of an education program for end users, and ongoing pathway improvement. The pathway was implemented on May 31, 2012. Quality metrics before and after implementation were compared. External data were used to analyze cost impacts. RESULTS: Significant improvements were achieved across multiple quality dimensions. Time to recovery decreased: mean length of stay was 1.30 days for 117 prepathway patients compared with 0.87 days for 69 postpathway patients (P < .001). Efficiency was enhanced: mean time to phototherapy initiation was 101.26 minutes for 14 prepathway patients compared with 54.67 minutes for 67 postpathway patients (P = .03). Care was less invasive: intravenous fluid orders were reduced from 80% to 44% (P < .001). Inpatient use was reduced: 66% of prepathway patients were admitted from the emergency department to inpatient care, compared with 50% of postpathway patients (P = .01). There was no increase in the readmission rate. These achievements translated to statistically significant cost reductions in total charges, as well as in the following categories: intravenous fluids, laboratory, room cost, and emergency department charges. CONCLUSIONS: An evidence based standard care pathway for neonatal jaundice can significantly improve multiple dimensions of value, including reductions in cost and length of stay.

AB - OBJECTIVES: To describe firearm storage practices in homes with children who have versus do not have self-harm risk factors. METHODS: A cross-sectional analysis of a nationally representative probability-based online survey of US adults conducted in 2015 (n = 3949; response rate 55%). Respondents self-reported whether they lived with children and were a caretaker/health care decision-maker for a child. Household firearm ownership was ascertained for all respondents; how firearms were stored in homes with guns was asked of gun owning respondents only; all respondents were asked whether their child had a history of the following self-harm risk factors: depression, mental health conditions other than depression, or attention-deficit/hyperactivity disorder. RESULTS: Household firearms were present in 43.5% (95% confidence interval [CI]: 34.4-64.7) of homes with children who had a history of self-harm risk factors (n = 52), compared with 42.3% (95% CI: 35.2-49.7) of homes in which no child had self-harm risk factors (n = 411). Among parents or caretakers with firearms, 34.9% (95 % CI: 20.2-53.2) stored all guns locked and unloaded when they had a child with a history self harm risk factors, compared with 31.8% (95% CI: 25.9-38.3) when none of their children had such a history. CONCLUSIONS: Millions of US children live in homes in which firearms are left loaded or unlocked or both. A child's history of depression, mental health conditions other than depression, or attention deficit/hyperactivity disorder does not appear to appreciably influence caretaker decisions about whether to (1) have firearms in the home, or (2) store all household firearms in accordance with American Academy of Pediatrics recommendations (ie, locked and unloaded).

PMID- 29467281 TI - The MYO6 interactome reveals adaptor complexes coordinating early endosome and cytoskeletal dynamics. AB - The intracellular functions of myosin motors requires a number of adaptor molecules, which control cargo attachment, but also fine-tune motor activity in time and space. These motor-adaptor-cargo interactions are often weak, transient or highly regulated. To overcome these problems, we use a proximity labelling based proteomics strategy to map the interactome of the unique minus end-directed actin motor MYO6. Detailed biochemical and functional analysis identified several distinct MYO6-adaptor modules including two complexes containing RhoGEFs: the LIFT (LARG-Induced F-actin for Tethering) complex that controls endosome positioning and motility through RHO-driven actin polymerisation; and the DISP (DOCK7-Induced Septin disPlacement) complex, a novel regulator of the septin cytoskeleton. These complexes emphasise the role of MYO6 in coordinating endosome dynamics and cytoskeletal architecture. This study provides the first in vivo interactome of a myosin motor protein and highlights the power of this approach in uncovering dynamic and functionally diverse myosin motor complexes. PMID- 29467282 TI - Proteomic profiling of VCP substrates links VCP to K6-linked ubiquitylation and c Myc function. AB - Valosin-containing protein (VCP) is an evolutionarily conserved ubiquitin dependent ATPase that mediates the degradation of proteins through the ubiquitin proteasome pathway. Despite the central role of VCP in the regulation of protein homeostasis, identity and nature of its cellular substrates remain poorly defined. Here, we combined chemical inhibition of VCP and quantitative ubiquitin remnant profiling to assess the effect of VCP inhibition on the ubiquitin modified proteome and to probe the substrate spectrum of VCP in human cells. We demonstrate that inhibition of VCP perturbs cellular ubiquitylation and increases ubiquitylation of a different subset of proteins compared to proteasome inhibition. VCP inhibition globally upregulates K6-linked ubiquitylation that is dependent on the HECT-type ubiquitin E3 ligase HUWE1. We report ~450 putative VCP substrates, many of which function in nuclear processes, including gene expression, DNA repair and cell cycle. Moreover, we identify that VCP regulates the level and activity of the transcription factor c-Myc.

AB - Activation of brown adipose tissue (BAT) and beige fat by cold increases energy expenditure. Although their activation is known to be differentially regulated in part by hypothalamus, the underlying neural pathways and populations remain poorly characterized. Here, we show that activation of rat-insulin-promoter-Cre (RIP-Cre) neurons in ventromedial hypothalamus (VMH) preferentially promotes recruitment of beige fat via a selective control of sympathetic nervous system (SNS) outflow to subcutaneous white adipose tissue (sWAT), but has no effect on BAT Genetic ablation of APPL2 in RIP-Cre neurons diminishes beiging in sWAT without affecting BAT, leading to cold intolerance and obesity in mice. Such defects are reversed by activation of RIP-Cre neurons, inactivation of VMH AMPK, or treatment with a beta3-adrenergic receptor agonist. Hypothalamic APPL2 enhances neuronal activation in VMH RIP-Cre neurons and raphe pallidus, thereby eliciting SNS outflow to sWAT and subsequent beiging. These data suggest that beige fat can be selectively activated by VMH RIP-Cre neurons, in which the APPL2 AMPK signaling axis is crucial for this defending mechanism to cold and obesity. PMID- 29467284 TI - Adult-born neurons boost odor-reward association. AB - Olfaction is an important sensory modality driving fundamental behaviors. During odor-dependent learning, a positive value is commonly assigned to an odorant, and multiple forms of plasticity are involved when such odor-reward associations are formed. In rodents, one of the mechanisms underlying plasticity in the olfactory bulb consists in recruiting new neurons daily throughout life. However, it is still unknown whether adult-born neurons might participate in encoding odor value. Here, we demonstrate that exposure to reward-associated odors specifically increases activity of adult-born neurons but not preexisting neurons. Remarkably, adult-born neuron activation during rewarded odor presentation heightens discrimination learning and enhances the ability to update the odor value during reversal association. Moreover, in some cases, activation of this interneuron population can trigger olfactory learning without sensory stimulation. Taken together, our results show a specific involvement of adult-born neurons in facilitating odor-reward association during adaptive learning. PMID- 29467285 TI - Angiogenic patterning by STEEL, an endothelial-enriched long noncoding RNA. AB - Endothelial cell (EC)-enriched protein coding genes, such as endothelial nitric oxide synthase (eNOS), define quintessential EC-specific physiologic functions. It is not clear whether long noncoding RNAs (lncRNAs) also define cardiovascular cell type-specific phenotypes, especially in the vascular endothelium. Here, we report the existence of a set of EC-enriched lncRNAs and define a role for spliced-transcript endothelial-enriched lncRNA (STEEL) in angiogenic potential, macrovascular/microvascular identity, and shear stress responsiveness. STEEL is expressed from the terminus of the HOXD locus and is transcribed antisense to HOXD transcription factors. STEEL RNA increases the number and integrity of de novo perfused microvessels in an in vivo model and augments angiogenesis in vitro. The STEEL RNA is polyadenylated, nuclear enriched, and has microvascular predominance. Functionally, STEEL regulates a number of genes in diverse ECs. Of interest, STEEL up-regulates both eNOS and the transcription factor Kruppel-like factor 2 (KLF2), and is subject to feedback inhibition by both eNOS and shear augmented KLF2. Mechanistically, STEEL up-regulation of eNOS and KLF2 is transcriptionally mediated, in part, via interaction of chromatin-associated STEEL with the poly-ADP ribosylase, PARP1. For instance, STEEL recruits PARP1 to the KLF2 promoter. This work identifies a role for EC-enriched lncRNAs in the phenotypic adaptation of ECs to both body position and hemodynamic forces and establishes a newer role for lncRNAs in the transcriptional regulation of EC identity.

AB - Viruses are the most abundant biological entities and carry a wide variety of genetic material, including the ability to encode host-like proteins.

Among the strongest homologies were those for four viral insulin/IGF-1-like peptides (VILPs), each encoded by a different member of the family Iridoviridae VILPs show up to 50% homology to human insulin/IGF-1, contain all critical cysteine residues, and are predicted to form similar 3D structures. Chemically synthesized VILPs can bind to human and murine IGF-1/insulin receptors and stimulate receptor autophosphorylation and downstream signaling. VILPs can also increase glucose uptake in adipocytes and stimulate the proliferation of fibroblasts, and injection of VILPs into mice significantly lowers blood glucose. Transfection of mouse hepatocytes with DNA encoding a VILP also stimulates insulin/IGF-1 signaling and DNA synthesis. Human microbiome studies reveal the presence of these Iridoviridae in blood and fecal samples. Thus, VILPs are members of the insulin/IGF superfamily with the ability to be active on human and rodent cells, raising the possibility for a potential role of VILPs in human disease. Furthermore, since only 2% of viruses have been sequenced, this study raises the potential for discovery of other viral hormones which, along with known virally encoded growth factors, may modify human health and disease. PMID- 29467287 TI - Revealing nascent proteomics in signaling pathways and cell differentiation. AB - Regulation of gene expression at the level of protein synthesis is a crucial element in driving how the genetic landscape is expressed. However, we are still limited in technologies that can quantitatively capture the immediate proteomic changes that allow cells to respond to specific stimuli. Here, we present a method to capture and identify nascent proteomes in situ across different cell types without disturbing normal growth conditions, using O-propargyl-puromycin (OPP). Cell-permeable OPP rapidly labels nascent elongating polypeptides, which are subsequently conjugated to biotin-azide, using click chemistry, and captured with streptavidin beads, followed by digestion and analysis, using liquid chromatography-tandem mass spectrometry. Our technique of OPP-mediated identification (OPP-ID) allows detection of widespread proteomic changes within a short 2-hour pulse of OPP. We illustrate our technique by recapitulating alterations of proteomic networks induced by a potent mammalian target of rapamycin inhibitor, MLN128. In addition, by employing OPP-ID, we identify more than 2,100 proteins and uncover distinct protein networks underlying early erythroid progenitor and differentiation states not amenable to alternative approaches such as amino acid analog labeling. We present OPP-ID as a method to quantitatively identify nascent proteomes across an array of biological contexts while preserving the subtleties directing signaling in the native cellular environment. PMID- 29467288 TI - Molecular basis for diversification of yeast prion strain conformation. AB - Self-propagating beta-sheet-rich fibrillar protein aggregates, amyloid fibers, are often associated with cellular dysfunction and disease. Distinct amyloid conformations dictate different physiological consequences, such as cellular toxicity. However, the origin of the diversity of amyloid conformation remains unknown. Here, we suggest that altered conformational equilibrium in natively disordered monomeric proteins leads to the adaptation of alternate amyloid conformations that have different phenotypic effects. We performed a comprehensive high-resolution structural analysis of Sup35NM, an N-terminal fragment of the Sup35 yeast prion protein, and found that monomeric Sup35NM harbored latent local compact structures despite its overall disordered conformation. When the hidden local microstructures were relaxed by genetic mutations or solvent conditions, Sup35NM adopted a strikingly different amyloid conformation, which redirected chaperone-mediated fiber fragmentation and modulated prion strain phenotypes. Thus, dynamic conformational fluctuations in natively disordered monomeric proteins represent a posttranslational mechanism for diversification of aggregate structures and cellular phenotypes. PMID- 29467290 TI - New sources for the emergence of new invaders. PMID- 29467289 TI - Protonation state of inhibitors determines interaction sites within voltage-gated sodium channels. AB - Voltage-gated sodium channels are essential for carrying electrical signals throughout the body, and mutations in these proteins are responsible for a variety of disorders, including epilepsy and pain syndromes. As such, they are the target of a number of drugs used for reducing pain or combatting arrhythmias and seizures. However, these drugs affect all sodium channel subtypes found in the body. Designing compounds to target select sodium channel subtypes will provide a new therapeutic pathway and would maximize treatment efficacy while minimizing side effects. Here, we examine the binding preferences of nine compounds known to be sodium channel pore blockers in molecular dynamics simulations. We use the approach of replica exchange solute tempering (REST) to gain a more complete understanding of the inhibitors' behavior inside the pore of NavMs, a bacterial sodium channel, and NavPas, a eukaryotic sodium channel. Using these simulations, we are able to show that both charged and neutral compounds partition into the bilayer, but neutral forms more readily cross it. We show that there are two possible binding sites for the compounds: (i) a site on helix 6, which has been previously determined by many experimental and computational studies, and (ii) an additional site, occupied by protonated compounds in which the positively charged part of the drug is attracted into the selectivity filter. Distinguishing distinct binding poses for neutral and charged compounds is essential for understanding the nature of pore block and will aid the design of subtype-selective sodium channel inhibitors. PMID- 29467292 TI - Trophic redundancy reduces vulnerability to extinction cascades. AB - Current species extinction rates are at unprecedentedly high levels. While human activities can be the direct cause of some extinctions, it is becoming increasingly clear that species extinctions themselves can be the cause of further extinctions, since species affect each other through the network of ecological interactions among them. There is concern that the simplification of ecosystems, due to the loss of species and ecological interactions, increases their vulnerability to such secondary extinctions. It is predicted that more complex food webs will be less vulnerable to secondary extinctions due to greater trophic redundancy that can buffer against the effects of species loss. Here, we demonstrate in a field experiment with replicated plant-insect communities, that the probability of secondary extinctions is indeed smaller in food webs that include trophic redundancy. Harvesting one species of parasitoid wasp led to secondary extinctions of other, indirectly linked, species at the same trophic level. This effect was markedly stronger in simple communities than for the same species within a more complex food web. We show that this is due to functional redundancy in the more complex food webs and confirm this mechanism with a food web simulation model by highlighting the importance of the presence and strength of trophic links providing redundancy to those links that were lost. Our results demonstrate that biodiversity loss, leading to a reduction in redundant interactions, can increase the vulnerability of ecosystems to secondary extinctions, which, when they occur, can then lead to further simplification and run-away extinction cascades. PMID- 29467291 TI - Epigenetic alterations in longevity regulators, reduced life span, and exacerbated aging-related pathology in old father offspring mice. AB - Advanced age is not only a major risk factor for a range of disorders within an aging individual but may also enhance susceptibility for disease in the next generation. In humans, advanced paternal age has been associated with increased risk for a number of diseases. Experiments in rodent models have provided initial evidence that paternal age can influence behavioral traits in offspring animals, but the overall scope and extent of paternal age effects on health and disease across the life span remain underexplored. Here, we report that old father offspring mice showed a reduced life span and an exacerbated development of aging traits compared with young father offspring mice. Genome-wide epigenetic analyses of sperm from aging males and old father offspring tissue identified differentially methylated promoters, enriched for genes involved in the regulation of evolutionarily conserved longevity pathways. Gene expression analyses, biochemical experiments, and functional studies revealed evidence for an overactive mTORC1 signaling pathway in old father offspring mice. Pharmacological mTOR inhibition during the course of normal aging ameliorated many of the aging traits that were exacerbated in old father offspring mice. These findings raise the possibility that inherited alterations in longevity pathways contribute to intergenerational effects of aging in old father offspring mice.

AB - Radiation-induced intestinal fibrosis (RIF) is a serious complication after abdominal radiotherapy for pelvic tumor or peritoneal metastasis. Herein, we show that RIF is mediated by eosinophil interactions with alpha-smooth muscle actin positive (alpha-SMA+) stromal cells. Abdominal irradiation caused RIF especially in the submucosa (SM) of the small intestine, which was associated with the excessive accumulation of eosinophils in both human and mouse. Eosinophil deficient mice showed markedly ameliorated RIF, suggesting the importance of eosinophils. After abdominal irradiation, chronic crypt cell death caused elevation of extracellular adenosine triphosphate, which in turn activated expression of C-C motif chemokine 11 (CCL11) by pericryptal alpha-SMA+ cells in the SM to attract eosinophils in mice. Inhibition of C-C chemokine receptor 3 (CCR3) by genetic deficiency or neutralizing antibody (Ab) treatment suppressed eosinophil accumulation in the SM after irradiation in mice, suggesting a critical role of the CCL11/CCR3 axis in the eosinophil recruitment. Activated alpha-SMA+ cells also expressed granulocyte-macrophage colony-stimulating factor (GM-CSF) to activate eosinophils. Transforming growth factor-beta1 from GM-CSF stimulated eosinophils promoted collagen expression by alpha-SMA+ cells. In translational studies, treatment with a newly developed interleukin-5 receptor alpha-targeting Ab, analogous to the human agent benralizumab, depleted intestinal eosinophils and suppressed RIF in mice. Collectively, we identified eosinophils as a crucial factor in the pathogenesis of RIF and showed potential therapeutic strategies for RIF by targeting eosinophils. PMID- 29467299 TI - In situ formed reactive oxygen species-responsive scaffold with gemcitabine and checkpoint inhibitor for combination therapy. AB - Patients with low-immunogenic tumors respond poorly to immune checkpoint blockade (ICB) targeting the programmed death-1 (PD-1)/programmed death-ligand 1 (PD-L1) pathway. Conversely, patients responding to ICB can experience various side effects. We have thus engineered a therapeutic scaffold that, when formed in situ, allows the local release of gemcitabine (GEM) and an anti-PD-L1 blocking antibody (aPDL1) with distinct release kinetics. The scaffold consists of reactive oxygen species (ROS)-degradable hydrogel that releases therapeutics in a programmed manner within the tumor microenvironment (TME), which contains abundant ROS. We found that the aPDL1-GEM scaffold elicits an immunogenic tumor phenotype and promotes an immune-mediated tumor regression in the tumor-bearing mice, with prevention of tumor recurrence after primary resection. PMID- 29467298 TI - Microhemorrhage-associated tissue iron enhances the risk for Aspergillus fumigatus invasion in a mouse model of airway transplantation. AB - Invasive pulmonary disease due to the mold Aspergillus fumigatus can be life threatening in lung transplant recipients, but the risk factors remain poorly understood. To study this process, we used a tracheal allograft mouse model that recapitulates large airway changes observed in patients undergoing lung transplantation. We report that microhemorrhage-related iron content may be a major determinant of A. fumigatus invasion and, consequently, its virulence. Invasive growth was increased during progressive alloimmune-mediated graft rejection associated with high concentrations of ferric iron in the graft. The role of iron in A. fumigatus invasive growth was further confirmed by showing that this invasive phenotype was increased in tracheal transplants from donor mice lacking the hemochromatosis gene (Hfe-/- ). The invasive phenotype was also increased in mouse syngrafts treated with topical iron solution and in allograft recipients receiving deferoxamine, a chelator that increases iron bioavailability to the mold. The invasive growth of the iron-intolerant A. fumigatus double knockout mutant (DeltasreA/DeltacccA) was lower than that of the wild-type mold. Alloimmune-mediated microvascular damage and iron overload did not appear to impair the host's immune response. In human lung transplant recipients, positive staining for iron in lung transplant tissue was more commonly seen in endobronchial biopsy sections from transplanted airways than in biopsies from the patients' own airways. Collectively, these data identify iron as a major determinant of A. fumigatus invasive growth and a potential target to treat or prevent A. fumigatus infections in lung transplant patients. PMID- 29467300 TI - High-throughput metabolomic analysis predicts mode of action of uncharacterized antimicrobial compounds. AB - Rapidly spreading antibiotic resistance and the low discovery rate of new antimicrobial compounds demand more effective strategies for early drug discovery. One bottleneck in the drug discovery pipeline is the identification of the modes of action (MoAs) of new compounds. We have developed a rapid systematic metabolome profiling strategy to classify the MoAs of bioactive compounds. The method predicted MoA-specific metabolic responses in the nonpathogenic bacterium Mycobacterium smegmatis after treatment with 62 reference compounds with known MoAs and different metabolic and nonmetabolic targets. We then analyzed a library of 212 new antimycobacterial compounds with unknown MoAs from a drug discovery effort by the pharmaceutical company GlaxoSmithKline (GSK). More than 70% of these new compounds induced metabolic responses in M. smegmatis indicative of known MoAs, seven of which were experimentally validated. Only 8% (16) of the compounds appeared to target unconventional cellular processes, illustrating the difficulty in discovering new antibiotics with different MoAs among compounds used as monotherapies. For six of the GSK compounds with potentially new MoAs, the metabolome profiles suggested their ability to interfere with trehalose and lipid metabolism. This was supported by whole-genome sequencing of spontaneous drug-resistant mutants of the pathogen Mycobacterium tuberculosis and in vitro compound-proteome interaction analysis for one of these compounds. Our compendium of drug-metabolome profiles can be used to rapidly query the MoAs of uncharacterized antimicrobial compounds and should be a useful resource for the drug discovery community. PMID- 29467302 TI - Alzheimer disease biomarkers and synucleinopathy. PMID- 29467303 TI - Focal myositis: New insights on diagnosis and pathology. AB - OBJECTIVE: To better define in a cohort study the clinical and pathologic features of focal myositis (FM). METHODS: With the use of the usual clinicopathologic definition, each confirmed case of FM in the Lyon University Hospital's myopathologic database between 2000 and 2016 was retrieved. Clinical, pathologic, imaging, serologic, and therapeutic data were collected. When data were missing but feasible, appropriate pathologic analyses were performed. RESULTS: Of the 924 patients included in the database, 37 (4%) had confirmed FM (14 female, 23 male patients). The main symptoms were pain (n = 30, 81%), muscular mass (n = 16, 43%), erythema at the site of FM (n = 12, 32%), and fever (n = 9, 24%). Serum creatine kinase was normal in most patients (81%); serum immune abnormalities were frequent (inflammatory syndrome in sera [39%], dysglobulinemia [52%], and anti-nuclear antibody positivity [29%]). In addition to confirming previously reported findings, pathologic analyses found significant rates of vasculitis (68%) and fasciitis (73%). Here, FM appeared frequently to be associated with other diseases such as immune-mediated inflammatory disease (IMID; 32%), neoplasia (24%), and radiculopathy (11%). Regarding outcomes, 64% of the cases had received immunosuppressive drugs, and the relapse rate was 41%. CONCLUSION: The present study suggests that FM is not as innocuous as previously believed, particularly considering the associated disorders. Notably, patients with FM should receive careful IMID and neoplasia screening. PMID- 29467304 TI - Association between implementation of a code stroke system and poststroke epilepsy. AB - OBJECTIVE: We aimed to investigate the effect of a code stroke system on the development of poststroke epilepsy. METHODS: We retrospectively analyzed consecutive patients treated with IV thrombolysis under or outside the code stroke system between 2003 and 2012. Patients were followed up for at least 2 years or until death. Factors with p < 0.1 in univariate comparisons were selected for multivariable logistic and Cox regression. RESULTS: A total of 409 patients met the eligibility criteria. Their median age at stroke onset was 75 years (interquartile range 64-83 years); 220 (53.8%) were male. The median follow up duration was 1,074 days (interquartile range 119-1,671 days). Thirty-two patients (7.8%) had poststroke seizures during follow-up, comprising 7 (1.7%) with acute symptomatic seizures and 25 (6.1%) with late-onset seizures. Twenty six patients (6.4%) fulfilled the definition of poststroke epilepsy. Three hundred eighteen patients (77.8%) were treated with the code stroke system while 91 (22.2%) were not. After adjustment for age and stroke etiology, use of the code stroke system was associated with decreased odds of poststroke epilepsy (odds ratio = 0.36, 95% confidence interval 0.14-0.87, p = 0.024). Cox regression showed lower adjusted hazard rates for poststroke epilepsy within 5 years for patients managed under the code stroke system (hazard ratio = 0.60, 95% confidence interval 0.47-0.79, p < 0.001). CONCLUSION: The code stroke system was associated with reduced odds and instantaneous risk of poststroke epilepsy. Further studies are required to identify the contribution of the individual components and mechanisms against epileptogenesis after stroke. CLASSIFICATION OF EVIDENCE: This study provides Class III evidence that for people with acute ischemic stroke, implementation of a code stroke system reduces the risk of poststroke epilepsy. PMID- 29467301 TI - Oncogenic JAK2V617F causes PD-L1 expression, mediating immune escape in myeloproliferative neoplasms. AB - Recent evidence has revealed that oncogenic mutations may confer immune escape. A better understanding of how an oncogenic mutation affects immunosuppressive programmed death ligand 1 (PD-L1) expression may help in developing new therapeutic strategies. We show that oncogenic JAK2 (Janus kinase 2) activity caused STAT3 (signal transducer and activator of transcription 3) and STAT5 phosphorylation, which enhanced PD-L1 promoter activity and PD-L1 protein expression in JAK2V617F-mutant cells, whereas blockade of JAK2 reduced PD-L1 expression in myeloid JAK2V617F-mutant cells. PD-L1 expression was higher on primary cells isolated from patients with JAK2V617F-myeloproliferative neoplasms (MPNs) compared to healthy individuals and declined upon JAK2 inhibition. JAK2V617F mutational burden, pSTAT3, and PD-L1 expression were highest in primary MPN patient-derived monocytes, megakaryocytes, and platelets. PD-1 (programmed death receptor 1) inhibition prolonged survival in human MPN xenograft and primary murine MPN models. This effect was dependent on T cells. Mechanistically, PD-L1 surface expression in JAK2V617F-mutant cells affected metabolism and cell cycle progression of T cells. In summary, we report that in MPN, constitutive JAK2/STAT3/STAT5 activation, mainly in monocytes, megakaryocytes, and platelets, caused PD-L1-mediated immune escape by reducing T cell activation, metabolic activity, and cell cycle progression. The susceptibility of JAK2V617F-mutant MPN to PD-1 targeting paves the way for immunomodulatory approaches relying on PD-1 inhibition. PMID- 29467306 TI - Gait analysis in PSP and NPH: Dual-task conditions make the difference. AB - OBJECTIVE: To test whether quantitative gait analysis of gait under single- and dual-task conditions can be used for a differential diagnosis of progressive supranuclear palsy (PSP) and idiopathic normal-pressure hydrocephalus (iNPH). METHODS: In this cross-sectional study, temporal and spatial gait parameters were analyzed in 38 patients with PSP (Neurological Disorders and Stroke and Society for Progressive Supranuclear Palsy diagnostic criteria), 27 patients with iNPH (international iNPH guidelines), and 38 healthy controls. A pressure-sensitive carpet was used to examine gait under 5 conditions: single task (preferred, slow, and maximal speed), cognitive dual task (walking with serial 7 subtractions), and motor dual task (walking while carrying a tray). RESULTS: The main results were as follows. First, both patients with PSP and those with iNPH exhibited significant gait dysfunction, which was worse in patients with iNPH with a more broad-based gait (p < 0.001). Second, stride time variability was increased in both patient groups, more pronounced in PSP (p = 0.009). Third, cognitive dual task led to a greater reduction of gait velocity in PSP (PSP 34.4% vs iNPH 16.9%, p = 0.002). Motor dual task revealed a dissociation of gait performance: patients with PSP considerably worsened, but patients with iNPH tended to improve. CONCLUSION: Patients with PSP seem to be more sensitive to dual-task perturbations than patients with iNPH. An increased step width and anisotropy of the effect of dual-task conditions (cognitive vs motor) seem to be good diagnostic tools for iNPH. PMID- 29467305 TI - CSF tau and beta-amyloid predict cerebral synucleinopathy in autopsied Lewy body disorders. AB - OBJECTIVE: To test the association of antemortem CSF biomarkers with postmortem pathology in Lewy body disorders (LBD). METHODS: Patients with autopsy-confirmed LBD (n = 24) and autopsy-confirmed Alzheimer disease (AD) (n = 23) and cognitively normal (n = 36) controls were studied. In LBD, neuropathologic criteria defined Lewy body alpha-synuclein (SYN) stages with medium/high AD copathology (SYN + AD = 10) and low/no AD copathology (SYN - AD = 14). Ordinal pathology scores for tau, beta-amyloid (Abeta), and SYN pathology were averaged across 7 cortical regions to obtain a global cerebral score for each pathology. CSF total tau (t-tau), phosphorylated tau at threonine181, and Abeta1-42 levels were compared between LBD and control groups and correlated with global cerebral pathology scores in LBD with linear regression. Diagnostic accuracy for postmortem categorization of LBD into SYN + AD vs SYN - AD or neocortical vs brainstem/limbic SYN stage was tested with receiver operating curves. RESULTS: SYN + AD had higher CSF t-tau (mean difference 27.0 +/- 8.6 pg/mL) and lower Abeta1-42 (mean difference -84.0 +/- 22.9 g/mL) compared to SYN - AD (p < 0.01, both). Increasing global cerebral tau and plaque scores were associated with higher CSF t-tau (R2 = 0.15-0.16, p < 0.05, both) and lower Abeta1-42 (R2 = 0.43 0.49, p < 0.001, both), while increasing cerebral SYN scores were associated with lower CSF Abeta1-42 (R2 = 0.31, p < 0.001) and higher CSF t-tau/Abeta1-42 ratio (R2 = 0.27, p = 0.01). CSF t-tau/Abeta1-42 ratio had 100% specificity and 90% sensitivity for SYN + AD, and CSF Abeta1-42 had 77% specificity and 82% sensitivity for neocortical SYN stage. CONCLUSIONS: Higher antemortem CSF t tau/Abeta1-42 and lower Abeta1-42 levels are predictive of increasing cerebral AD and SYN pathology. These biomarkers may identify patients with LBD vulnerable to cortical SYN pathology who may benefit from both SYN and AD-targeted disease modifying therapies. PMID- 29467307 TI - Effects of ATX-MS-1467 immunotherapy over 16 weeks in relapsing multiple sclerosis. AB - OBJECTIVE: To assess safety, tolerability, and efficacy of the antigen-specific immunotherapy ATX-MS-1467 in participants with relapsing multiple sclerosis using different treatment protocols to induce tolerance. METHODS: Two open-label trials in adult participants with relapsing multiple sclerosis were conducted. Study 1 was a multicenter, phase 1b safety evaluation comparing intradermal (i.d.) (cohort 1) with subcutaneous (cohort 2) administration in 43 participants. Both cohorts received ATX-MS-1467 dosed at 25, 50, 100, 400, and 800 MUg at 14-day intervals over 8 weeks, followed by 8 weeks with 4 additional 800-MUg doses at 14 day intervals and 32 weeks off study medication. Study 2 was a phase 2a, multicenter, single-arm trial enrolling 37 participants. ATX-MS-1467 was titrated from 50 MUg i.d. on day 1 to 200 MUg on day 15 and 800 MUg on day 29 followed by biweekly administration of 800 MUg for 16 weeks and 16 weeks off study medication. Efficacy was evaluated on MRI parameters and clinical variables. Safety endpoints included treatment-emergent adverse events and injection-site reactions. RESULTS: In study 1, there was a significant decrease in new/persisting T1 gadolinium-enhanced (GdE) lesions in cohort 1 from baseline to week 16, returning to baseline values at week 48. In study 2, the number of T1 GdE lesions were significantly reduced on treatment and remained reduced at study completion. Safety results were unremarkable in both studies. CONCLUSION: Relatively slow ATX-MS-1467 titration and a longer full-dose i.d. treatment period is associated with reduction in GdE lesions and a sustained effect post treatment. Further trials of ATX-MS-1467 are warranted. CLASSIFICATION OF EVIDENCE: This work provides Class IV evidence that for patients with relapsing multiple sclerosis, slow ATX-MS-1467 titration and a longer full-dose i.d. treatment period is associated with reduction in GdE lesions. PMID- 29467309 TI - Higher CYP2E1 Activity Correlates with Hepatocarcinogenesis Induced by Diethylnitrosamine. AB - Hepatocellular carcinoma (HCC) is one of the most common types of primary liver cancer and the third most frequent cause of cancer death worldwide. Diethylnitrosamine (DEN) is one of the recognized risk factors for hepatocarcinogenesis likely due to CYP2E1-mediated metabolic activation. However, CYP2E1-mediated DEN metabolic activity in non-neoplastic liver tissue from HCC patients has not been determined; the role of CYP2E1 activity, in particular CYP2E1 constitutive activity and CYP2E1 inhibited activity, with respect to the hepatocarcinogenesis induced by DEN is not yet clear. Herein, we determined CYP2E1-mediated DEN metabolic activity in non-neoplastic liver tissue from HCC patients and found that CYP2E1-mediated DEN metabolic activity was significantly elevated with a 43.3% positive rate, and clinicopathologic parameters did not affect the activity. Then, using a Sprague-Dawley rat liver tumor model induced by DEN, the relationship between CYP2E1 constitutive/inhibited activity and hepatocarcinogenesis was explored. The results showed that the CYP2E1 constitutive activity was strongly correlated with tumor incidence and severity of liver tumorigenesis (nodule numbers and size), whereas inhibition of CYP2E1 activity decreased hepatocyte proliferation, liver injury, and liver carcinogenesis in the presence of DEN. In conclusion, the higher CYP2E1 activity would lead to an increased incidence of HCC as a result of CYP2E1-mediated DEN activation. Therefore, higher CYP2E1 activity might be a risk factor for HCC induced by DEN. PMID- 29467308 TI - Comparing the Antiseizure and Neuroprotective Efficacy of LY293558, Diazepam, Caramiphen, and LY293558-Caramiphen Combination against Soman in a Rat Model Relevant to the Pediatric Population. AB - The currently Food and Drug Administration-approved anticonvulsant for the treatment of status epilepticus (SE) induced by nerve agents is the benzodiazepine diazepam; however, diazepam does not appear to offer neuroprotective benefits. This is of particular concern with respect to the protection of children because, in the developing brain, synaptic transmission mediated via GABAA receptors, the target of diazepam, is weak. In the present study, we exposed 21-day-old male rats to 1.2 * LD50 soman and compared the antiseizure, antilethality, and neuroprotective efficacy of diazepam (10 mg/kg), LY293558 (an AMPA/GluK1 receptor antagonist; 15 mg/kg), caramiphen (CRM, an antimuscarinic with NMDA receptor-antagonistic properties; 50 mg/kg), and LY293558 (15 mg/kg) + CRM (50 mg/kg), administered 1 hour after exposure. Diazepam, LY293558, and LY293558 + CRM, but not CRM alone, terminated SE; LY293558 + CRM treatment acted significantly faster and produced a survival rate greater than 85%. Thirty days after soman exposure, neurodegeneration in limbic regions was most severe in the CRM-treated group, minimal to severe-depending on the region-in the diazepam group, absent to moderate in the LY293558-treated group, and totally absent in the LY293558 + CRM group. Amygdala and hippocampal atrophy, a severe reduction in spontaneous inhibitory activity in the basolateral amygdala, and increased anxiety-like behavior in the open-field and acoustic startle response tests were present in the diazepam and CRM groups, whereas the LY293558 and LY293558 + CRM groups did not differ from controls. The combined administration of LY293558 and CRM, by blocking mainly AMPA, GluK1, and NMDA receptors, is a very effective anticonvulsant and neuroprotective therapy against soman in young rats. PMID- 29467310 TI - Whole-Body but Not Hepatic Knockdown of Chemerin by Antisense Oligonucleotide Decreases Blood Pressure in Rats. AB - Chemerin is an inflammatory adipokine positively associated with hypertension and obesity. The majority of chemerin derives from the liver and adipose tissue, however, their individual contributions to blood pressure are unknown. We began studying chemerin in the normal rat using antisense oligonucleotides (ASO) with whole-body activity (Gen 2.5 chemerin ASO) or liver-restricted activity (GalNAc chemerin ASO). We hypothesized that in normotensive male Sprague-Dawley rats, circulating chemerin is predominately liver-derived and regulates blood pressure. A dosing study of the Gen 2.5 chemerin ASO (with a scrambled control ASO) supported 25 mg/kg as the appropriate dose. GalNAc chemerin ASO was also assessed and used at 10 mg/kg. Radiotelemetry monitored mean arterial pressure (MAP) for a 1-week baseline and weekly subcutaneous ASO injections for 4 weeks. Two days after the final injection, animals were euthanized for tissue reverse transcription-polymerase chain reaction and chemerin Western analysis. Gen 2.5 chemerin ASO treatments reduced chemerin mRNA and protein in liver, retroperitoneal fat (RP), and mesenteric perivascular adipose tissue (mPVAT), as well as reducing protein in plasma. GalNAc chemerin ASO treatments reduced chemerin mRNA and protein in liver and chemerin protein in plasma but had no effect on expression in RP fat or mPVAT. Gen 2.5 chemerin ASO treatment reduced MAP compared with control ASO but was unchanged in animals receiving the GalNAc chemerin ASO. Although circulating chemerin is liver-derived, it does not play a major role in blood pressure regulation. Local effects of chemerin from fat may explain this discrepancy and support chemerin's association with hypertension and obesity. PMID- 29467311 TI - Epstein-Barr Virus Nuclear Antigen Leader Protein Coactivates EP300. AB - Epstein-Barr virus nuclear antigen (EBNA) leader protein (EBNALP) is one of the first viral genes expressed upon B-cell infection. EBNALP is essential for EBV mediated B-cell immortalization. EBNALP is thought to function primarily by coactivating EBNA2-mediated transcription. Chromatin immune precipitation followed by deep sequencing (ChIP-seq) studies highlight that EBNALP frequently cooccupies DNA sites with host cell transcription factors (TFs), in particular, EP300, implicating a broader role in transcription regulation. In this study, we investigated the mechanisms of EBNALP transcription coactivation through EP300. EBNALP greatly enhanced EP300 transcription activation when EP300 was tethered to a promoter. EBNALP coimmunoprecipitated endogenous EP300 from lymphoblastoid cell lines (LCLs). EBNALP W repeat serine residues 34, 36, and 63 were required for EP300 association and coactivation. Deletion of the EP300 histone acetyltransferase (HAT) domain greatly reduced EBNALP coactivation and abolished the EBNALP association. An EP300 bromodomain inhibitor also abolished EBNALP coactivation and blocked the EP300 association with EBNALP. EBNALP sites cooccupied by EP300 had significantly higher ChIP-seq signals for sequence specific TFs, including SPI1, RelA, EBF1, IRF4, BATF, and PAX5. EBNALP- and EP300 cooccurring sites also had much higher H3K4me1 and H3K27ac signals, indicative of activated enhancers. EBNALP-only sites had much higher signals for DNA looping factors, including CTCF and RAD21. EBNALP coactivated reporters under the control of NF-kappaB or SPI1. EP300 inhibition abolished EBNALP coactivation of these reporters. Clustered regularly interspaced short palindromic repeat interference targeting of EBNALP enhancer sites significantly reduced target gene expression, including that of EP300 itself. These data suggest a previously unrecognized mechanism by which EBNALP coactivates transcription through subverting of EP300 and thus affects the expression of LCL genes regulated by a broad range of host TFs.IMPORTANCE Epstein-Barr virus was the first human DNA tumor virus discovered over 50 years ago. EBV is causally linked to ~200,000 human malignancies annually. These cancers include endemic Burkitt lymphoma, Hodgkin lymphoma, lymphoma/lymphoproliferative disease in transplant recipients or HIV-infected people, nasopharyngeal carcinoma, and ~10% of gastric carcinoma cases. EBV immortalized human B cells faithfully model key aspects of EBV lymphoproliferative diseases and are useful models of EBV oncogenesis. EBNALP is essential for EBV to transform B cells and transcriptionally coactivates EBNA2 by removing repressors from EBNA2-bound DNA sites. Here, we found that EBNALP can also modulate the activity of the key transcription activator EP300, an acetyltransferase that activates a broad range of transcription factors. Our data suggest that EBNALP regulates a much broader range of host genes than was previously appreciated. A small-molecule inhibitor of EP300 abolished EBNALP coactivation of multiple target genes. These findings suggest novel therapeutic approaches to control EBV-associated lymphoproliferative diseases. PMID- 29467312 TI - Fibronectin Facilitates Enterovirus 71 Infection by Mediating Viral Entry. AB - Fibronectin (FN) is a high-molecular-weight extracellular matrix protein that contains the RGDS motif, which is required to bind to integrins. Synthetic RGDS peptides have been reported to compete with FN to bind to the cell surface and inhibit the function of FN. Here, we identified that synthetic RGDS peptides significantly inhibit human enterovirus 71 (EV71) infection in cell cultures. In addition, mice treated with RGDS peptides and infected with EV71 had a significantly higher survival rate and a lower viral load than the control group. Because RGDS peptides affect the function of FN, we questioned whether FN may play a role in virus infection. Our study indicates that overexpression of FN enhanced EV71 infection. In contrast, knockout of FN significantly reduced viral yield and decreased the viral binding to host cells. Furthermore, EV71 entry, rather than intracellular viral replication, was blocked by FN inhibitor pretreatment. Next, we found that FN could interact with the EV71 capsid protein VP1, and further truncated-mutation assays indicated that the D2 domain of FN could interact with the N-terminal fragment of VP1. Taken together, our results demonstrate that the host factor FN binds to EV71 particles and facilitates EV71 entry, providing a potential therapy target for EV71 infection.IMPORTANCE Hand, foot, and mouth disease outbreaks have occurred frequently in recent years, sometimes causing severe neurological complications and even death in infants and young children worldwide. Unfortunately, no effective antiviral drugs are available for human enterovirus 71 (EV71), one of the viruses that cause hand, foot, and mouth disease. The infection process and the host factors involved remain unknown, although several receptors have been identified. In this study, we found that the host factor fibronectin (FN) facilitated EV71 replication by interacting with EV71 particles and further mediated their entry. The RGDS peptide, an FN inhibitor, significantly inhibited EV71 replication in both RD cells and mice. In conclusion, our research identified a new host factor involved in EV71 infection, providing a new potential antiviral target for EV71 treatment. PMID- 29467313 TI - Reduced Chronic Lymphocyte Activation following Interferon Alpha Blockade during the Acute Phase of Simian Immunodeficiency Virus Infection in Rhesus Macaques. AB - Pathogenic human immunodeficiency virus (HIV)/simian immunodeficiency virus (SIV) infection of humans and rhesus macaques (RMs) induces persistently high production of type I interferon (IFN-I), which is thought to contribute to disease progression. To elucidate the specific role of interferon alpha (IFN alpha) in SIV pathogenesis, 12 RMs were treated prior to intravenous (i.v.) SIVmac239 infection with a high or a low dose of an antibody (AGS-009) that neutralizes most IFN-alpha subtypes and were compared with six mock-infused, SIV infected controls. Plasma viremia was measured postinfection to assess the effect of IFN-alpha blockade on virus replication, and peripheral blood and lymphoid tissue samples were analyzed by immunophenotypic staining. Consistent with the known antiviral effect of IFN-I, high-dose AGS-009 treatment induced a modest increase in acute-phase viral loads versus controls. Four out of 6 RMs receiving a high dose of AGS-009 also experienced an early decline in CD4+ T cell counts that was associated with progression to AIDS. Interestingly, 50% of the animals treated with AGS-009 (6/12) developed AIDS within 1 year of infection compared with 17% (1/6) of untreated controls. Finally, blockade of IFN-alpha decreased the levels of activated CD4+ and CD8+ T cells, as well as B cells, as measured by PD-1 and/or Ki67 expression. The lower levels of activated lymphocytes in IFN alpha-blockaded animals supports the hypothesis that IFN-alpha signaling contributes to lymphocyte activation during SIV infection and suggests that this signaling pathway is involved in controlling virus replication during acute infection. The potential anti-inflammatory effect of IFN-alpha blockade should be explored as a strategy to reduce immune activation in HIV-infected individuals.IMPORTANCE Interferon alpha (IFN-alpha) is a member of a family of molecules (type I interferons) that prevent or limit virus infections in mammals. However, IFN-alpha production may contribute to the chronic immune activation that is thought to be the primary cause of immune decline and AIDS in HIV infected patients. The study presented here attempts to understand the contribution of IFN-alpha to the natural history and progression of SIV infection of rhesus macaques, the primary nonhuman primate model system for testing hypotheses about HIV infection in humans. Here, we show that blockade of IFN alpha action promotes lower chronic immune activation but higher early viral loads, with a trend toward faster disease progression. This study has significant implications for new treatments designed to impact the type I interferon system. PMID- 29467314 TI - A prominent role of the human cytomegalovirus UL8 glycoprotein restraining pro inflammatory cytokine production by myeloid cells at late times during infection. AB - Human cytomegalovirus (HCMV) persistence in infected individuals relies on a plethora of mechanisms to efficiently reduce host immune responses. To that end, HCMV commits a variety of gene products, some of which have not been identified yet. Here we characterized the UL8 gene, which consists of two exons, sharing the first with the HCMV RL11 family member UL7 UL8 is a transmembrane protein with an N-terminal immunoglobulin (Ig)-like domain in common with UL7 but with an extended stalk and a distinctive cytoplasmic tail. The UL8 open reading frame gives rise to a heavily glycosylated protein, predominantly expressed on the cell surface, from where it can be partially endocytosed and subsequently degraded. Infections with UL8-tagged viruses indicated that UL8 was synthesized with late phase kinetics. By virtue of its highly conserved Ig-like domain, this viral protein interacted with a surface molecule present on activated neutrophils. Notably, when ectopically expressed in THP-1 myeloid cells, UL8 was able to significantly reduce the production of a variety of pro-inflammatory cytokines. Mutations in UL8 indicated that this functional effect was mediated by the cell surface expression of its Ig-like domain. To investigate the impact of the viral protein in the infection context, we engineered HCMVs lacking the UL8 gene, and demonstrated that UL8 decreases the release of a large number of pro-inflammatory factors at late times after infection of THP-1 cells. Our data indicate that UL8 may exert an immunosuppressive role key for HCMV survival in the host.IMPORTANCE Human cytomegalovirus (HCMV) is a major pathogen that causes life-threatening diseases and disabilities in infected newborns and immunocompromised individuals. Containing one of the largest genomes among all reported human viruses, HCMV encodes an impressive repertoire of gene products. However, the functions of a large proportion of them remain still unknown, a fact that complicates the design of new therapeutic approaches to prevent or treat HCMV associated diseases. In this report, we have conducted an extensive study of UL8, one of the previously uncharacterized HCMV open reading frames. We found that the UL8 protein is expressed at late times post infection and utilized by HCMV to reduce the production of pro-inflammatory factors by infected myeloid cells. Thus, the work presented here points to a key role of UL8 as a novel HCMV immune modulator capable to restrain host antiviral defenses. PMID- 29467315 TI - Plasmid Partitioning by Human Tumor Viruses. AB - The human tumor viruses that replicate as plasmids (we use the term plasmid to avoid any confusion in the term episome, which was coined to mean DNA elements that occur both extrachromosomally and as integrated forms during their life cycles, as does phage lambda) share many features in their DNA synthesis. We know less about their mechanisms of maintenance in proliferating cells, but these mechanisms must underlie their partitioning to daughter cells. One amazing implication of how these viruses are thought to maintain themselves is that while host chromosomes commit themselves to partitioning in mitosis, these tumor viruses would commit themselves to partitioning before mitosis and probably in S phase shortly after their synthesis. PMID- 29467316 TI - Formation of RNA Granule-Derived Capsid Assembly Intermediates Appears To Be Conserved between Human Immunodeficiency Virus Type 1 and the Nonprimate Lentivirus Feline Immunodeficiency Virus. AB - During immature capsid assembly in cells, human immunodeficiency virus type 1 (HIV-1) Gag co-opts a host RNA granule, forming a pathway of intracellular assembly intermediates containing host components, including two cellular facilitators of assembly, ABCE1 and DDX6. A similar assembly pathway has been observed for other primate lentiviruses. Here we asked whether feline immunodeficiency virus (FIV), a nonprimate lentivirus, also forms RNA granule derived capsid assembly intermediates. First, we showed that the released FIV immature capsid and a large FIV Gag-containing intracellular complex are unstable during analysis, unlike for HIV-1. We identified harvest conditions, including in situ cross-linking, that overcame this problem, revealing a series of FIV Gag containing complexes corresponding in size to HIV-1 assembly intermediates. Previously, we showed that assembly-defective HIV-1 Gag mutants are arrested at specific assembly intermediates; here we identified four assembly-defective FIV Gag mutants, including three not previously studied, and demonstrated that they appear to be arrested at the same intermediate as the cognate HIV-1 mutants. Further evidence that these FIV Gag-containing complexes correspond to assembly intermediates came from coimmunoprecipitations demonstrating that endogenous ABCE1 and the RNA granule protein DDX6 are associated with FIV Gag, as shown previously for HIV-1 Gag, but are not associated with a ribosomal protein, at steady state. Additionally, we showed that FIV Gag associates with another RNA granule protein, DCP2. Finally, we validated the FIV Gag-ABCE1 and FIV Gag-DCP2 interactions with proximity ligation assays demonstrating colocalization in situ Together, these data support a model in which primate and nonprimate lentiviruses form intracellular capsid assembly intermediates derived from nontranslating host RNA granules.IMPORTANCE Like HIV-1 Gag, FIV Gag assembles into immature capsids; however, it is not known whether FIV Gag progresses through a pathway of immature capsid assembly intermediates derived from host RNA granules, as shown for HIV-1 Gag. Here we showed that FIV Gag forms complexes that resemble HIV-1 capsid assembly intermediates in size and in their association with ABCE1 and DDX6, two host facilitators of HIV-1 immature capsid assembly that are found in HIV-1 assembly intermediates. Our studies also showed that known and novel assembly defective FIV Gag mutants fail to progress past putative intermediates in a pattern resembling that observed for HIV-1 Gag mutants. Finally, we used imaging to demonstrate colocalization of FIV Gag with ABCE1 and with the RNA granule protein DCP2. Thus, we conclude that formation of assembly intermediates derived from host RNA granules is likely conserved between primate and nonprimate lentiviruses and could provide targets for future antiviral strategies. PMID- 29467318 TI - Adenovirus infection of human enteroids reveals interferon sensitivity and preferential infection of goblet cells. AB - Human adenoviruses (HAdV) are significant human pathogens. Although only a subset of HAdV serotypes commonly cause gastroenteritis in humans, most HAdV species replicate in the gastrointestinal tract. Knowledge of the complex interaction between HAdVs and the human intestinal epithelium has been limited by the lack of a suitable cell culture system containing relevant cell types. Recently, this need has been met by the stable and prolonged cultivation of primary intestinal epithelial cells as enteroids. Human enteroids have been used to reveal novel and interesting aspects of rotavirus, norovirus, and enterovirus replication, prompting us to explore their suitability for HAdV culture. We found that both prototype strains and clinical isolates of enteric and non-enteric HAdVs productively replicate in human enteroids. HAdV-5p, a respiratory pathogen, and HAdV-41p, an enteric pathogen, are both sensitive to type I and III interferons in human enteroid monolayers but not A549 cells. Interestingly, HAdV-5p, but not HAdV-41p, preferentially infected goblet cells. And, HAdV-5p but not HAdV-41p was potently neutralized by the enteric human alpha-defensin HD5. These studies highlight new facets of HAdV biology that are uniquely revealed by primary intestinal epithelial cell culture.IMPORTANCE Enteric adenoviruses are a significant cause of childhood gastroenteritis worldwide, yet our understanding of their unique biology is limited. Here we report robust replication of both prototype and clinical isolates of enteric and respiratory human adenoviruses in enteroids, a primary intestinal cell culture system. Recent studies have shown that other fastidious enteric viruses replicate in human enteroids. Therefore, human enteroids may provide a unified platform for culturing enteric viruses, potentially enabling isolation of a greater diversity of viruses from patients. Moreover, both the ability of interferon to restrict respiratory and enteric adenoviruses and a surprising preference of a respiratory serotype for goblet cells demonstrates the power of this culture system to uncover aspects of adenovirus biology that were previously unattainable with standard cell lines. PMID- 29467317 TI - Bovine Nebovirus Interacts with a Wide Spectrum of Histo-Blood Group Antigens. AB - Some viruses within the Caliciviridae family initiate their replication cycle by attachment to cell surface carbohydrate moieties, histo-blood group antigens (HBGAs), and/or terminal sialic acids (SAs). Although bovine nebovirus (BNeV), one of the enteric caliciviruses, is an important causative agent of acute gastroenteritis in cattle, its attachment factors and possibly other cellular receptors remain unknown. Using a comprehensive series of protein-ligand biochemical assays, we sought to determine whether BNeV recognizes cell surface HBGAs and/or SAs as attachment factors. It was found that BNeV virus-like particles (VLPs) bound to A type/H type 2/Ley HBGAs expressed in the bovine digestive tract and are related to HBGAs expressed in humans and other host species, suggesting a wide spectrum of HBGA recognition by BNeV. BNeV VLPs also bound to a large variety of different bovine and human saliva samples of all ABH and Lewis types, supporting previously obtained results and suggesting a zoonotic potential of BNeV transmission. Removal of alpha1,2-linked fucose and alpha1,3/4 linked fucose epitopes of target HBGAs by confirmation-specific enzymes reduced the binding of BNeV VLPs to synthetic HBGAs, bovine and human saliva, cultured cell lines, and bovine small intestine mucosa, further supporting a wide HBGA binding spectrum of BNeV through recognition of alpha1,2-linked fucose and alpha1,3/4-linked fucose epitopes of targeted HBGAs. However, removal of terminal alpha2,3- and alpha2,6-linked SAs by their specific enzyme had no inhibitory effects on binding of BNeV VLPs, indicating that BNeV does not use terminal SAs as attachment factors. Further details of the binding specificity of BNeV remain to be explored.IMPORTANCE Enteric caliciviruses such as noroviruses, sapoviruses, and recoviruses are the most important etiological agents of severe acute gastroenteritis in humans and many other mammalian host species. They initiate infection by attachment to cell surface carbohydrate moieties, HBGAs, and/or terminal SAs. However, the attachment factor(s) for BNeV, a recently classified enteric calicivirus genus/type species, remains unexplored. Here, we demonstrate that BNeV VLPs have a wide spectrum of binding to synthetic HBGAs, bovine and human saliva samples, and bovine duodenal sections. We further discovered that alpha1,2-linked fucose and alpha1,3/4-linked fucose epitopes are essential for binding of BNeV VLPs. However, BNeV VLPs do not bind to terminal SAs on cell carbohydrates. Continued investigation regarding the proteinaceous receptor(s) will be necessary for better understanding of the tropism, pathogenesis, and host range of this important viral genus. PMID- 29467320 TI - Whatever happened to silence? PMID- 29467319 TI - Escape of Hepatitis C Virus from Epitope I Neutralization Increases Sensitivity of Other Neutralization Epitopes. AB - The hepatitis C virus (HCV) E2 glycoprotein is a major target of the neutralizing antibody (nAb) response, with multiple type-specific and broadly neutralizing antibody (bnAb) epitopes identified. The 412-to-423 region can generate bnAbs that block interaction with the cell surface receptor CD81, with activity toward multiple HCV genotypes. In this study, we reveal the structure of rodent monoclonal antibody 24 (MAb24) with an extensive contact area toward a peptide spanning the 412-to-423 region. The crystal structure of the MAb24-peptide 412-to 423 complex reveals the paratope bound to a peptide hairpin highly similar to that observed with human MAb HCV1 and rodent MAb AP33, but with a different angle of approach. In viral outgrowth experiments, we demonstrated three distinct genotype 2a viral populations that acquired resistance to MAb24 via N415D, N417S, and N415D/H386R mutations. Importantly, the MAb24-resistant viruses exhibited significant increases in sensitivity to the majority of bnAbs directed to epitopes within the 412-to-423 region and in additional antigenic determinants located within E2 and the E1E2 complex. This study suggests that modification of N415 causes a global change in glycoprotein structure that increases its vulnerability to neutralization by other antibodies. This finding suggests that in the context of an antibody response to viral infection, acquisition of escape mutations in the 412-to-423 region renders the virus more susceptible to neutralization by other specificities of nAbs, effectively reducing the immunological fitness of the virus. A vaccine for HCV that generates polyspecific humoral immunity with specificity for the 412-to-423 region and at least one other region of E2 is desirable.IMPORTANCE Understanding how antibodies neutralize hepatitis C virus (HCV) is essential for vaccine development. This study reveals for the first time that when HCV develops resistance to a major class of bnAbs targeting the 412-to-423 region of E2, this results in a concomitant increase in sensitivity to neutralization by a majority of other bnAb specificities. Vaccines for the prevention of HCV infection should therefore generate bnAbs directed toward the 412-to-423 region of E2 and additional bnAb epitopes within the viral glycoproteins. PMID- 29467321 TI - Development of MK-8353, an orally administered ERK1/2 inhibitor, in patients with advanced solid tumors. AB - BACKGROUND: Constitutive activation of ERK1/2 occurs in various cancers, and its reactivation is a well-described resistance mechanism to MAPK inhibitors. ERK inhibitors may overcome the limitations of MAPK inhibitor blockade. The dual mechanism inhibitor SCH772984 has shown promising preclinical activity across various BRAFV600/RAS-mutant cancer cell lines and human cancer xenografts. METHODS: We have developed an orally bioavailable ERK inhibitor, MK-8353; conducted preclinical studies to demonstrate activity, pharmacodynamic endpoints, dosing, and schedule; completed a study in healthy volunteers (P07652); and subsequently performed a phase I clinical trial in patients with advanced solid tumors (MK-8353-001). In the P07652 study, MK-8353 was administered as a single dose in 10- to 400-mg dose cohorts, whereas in the MK-8353-001 study, MK-8353 was administered in 100- to 800-mg dose cohorts orally twice daily. Safety, tolerability, pharmacokinetics, pharmacodynamics, and antitumor activity were analyzed. RESULTS: MK-8353 exhibited comparable potency with SCH772984 across various preclinical cancer models. Forty-eight patients were enrolled in the P07652 study, and twenty-six patients were enrolled in the MK-8353-001 study. Adverse events included diarrhea (44%), fatigue (40%), nausea (32%), and rash (28%). Dose-limiting toxicity was observed in the 400-mg and 800-mg dose cohorts. Sufficient exposure to MK-8353 was noted that correlated with biological activity in preclinical data. Three of fifteen patients evaluable for treatment response in the MK-8353-001 study had partial response, all with BRAFV600-mutant melanomas. CONCLUSION: MK-8353 was well tolerated up to 400 mg twice daily and exhibited antitumor activity in patients with BRAFV600-mutant melanoma. However, antitumor activity was not particularly correlated with pharmacodynamic parameters. TRIAL REGISTRATION: ClinicalTrials.gov NCT01358331.

PMID- 29467322 TI - Gut microbiota modulates adoptive cell therapy via CD8alpha dendritic cells and IL-12. AB - Adoptive T cell therapy (ACT) is a promising new modality for malignancies. Here, we report that adoptive T cell efficacy in tumor-bearing mice is significantly affected by differences in the native composition of the gut microbiome or treatment with antibiotics, or by heterologous fecal transfer. Depletion of bacteria with vancomycin decreased the rate of tumor growth in mice from The Jackson Laboratory receiving ACT, whereas treatment with neomycin and metronidazole had no effect, indicating the role of specific bacteria in host response. Vancomycin treatment induced an increase in systemic CD8alpha+ DCs, which sustained systemic adoptively transferred antitumor T cells in an IL-12 dependent manner. In subjects undergoing allogeneic hematopoietic cell transplantation, we found that oral vancomycin also increased IL-12 levels. Collectively, our findings demonstrate an important role played by the gut microbiota in the antitumor effectiveness of ACT and suggest potentially new avenues to improve response to ACT by altering the gut microbiota. PMID- 29467323 TI - Von Hippel-Lindau mutations disrupt vascular patterning and maturation via Notch. AB - Von Hippel-Lindau (VHL) gene mutations induce neural tissue hemangioblastomas, as well as highly vascularized clear cell renal cell carcinomas (ccRCCs). Pathological vessel remodeling arises from misregulation of HIFs and VEGF, among other genes. Variation in disease penetrance has long been recognized in relation to genotype. We show Vhl mutations also disrupt Notch signaling, causing mutation specific vascular abnormalities, e.g., type 1 (null) vs. type 2B (murine G518A representing human R167Q). In conditional mutation retina vasculature, Vhl-null mutation (i.e., UBCCreER/+Vhlfl/fl) had little effect on initial vessel branching, but it severely reduced arterial and venous branching at later stages. Interestingly, this mutation accelerated arterial maturation, as observed in retina vessel morphology and aberrant alpha-smooth muscle actin localization, particularly in vascular pericytes. RNA sequencing analysis identified gene expression changes within several key pathways, including Notch and smooth muscle cell contractility. Notch inhibition failed to reverse later-stage branching defects but rescued the accelerated arterialization. Retinal vessels harboring the type 2B Vhl mutation (i.e., UBCCreER/+Vhlfl/2B) displayed stage-specific changes in vessel branching and an advanced progression toward an arterial phenotype. Disrupting Notch signaling in type 2B mutants increased both artery and vein branching and restored arterial maturation toward nonmutant levels. By revealing differential effects of the null and type 2B Vhl mutations on vessel branching and maturation, these data may provide insight into the variability of VHL-associated vascular changes - particularly the heterogeneity and aggressiveness in ccRCC vessel growth - and also suggest Notch pathway targets for treating VHL syndrome. PMID- 29467324 TI - Angiokine Wisp-1 is increased in myocardial infarction and regulates cardiac endothelial signaling. AB - Myocardial infarctions (MIs) cause the loss of myocytes due to lack of sufficient oxygenation and latent revascularization. Although the administration of histone deacetylase (HDAC) inhibitors reduces the size of infarctions and improves cardiac physiology in small-animal models of MI injury, the cellular targets of the HDACs, which the drugs inhibit, are largely unspecified. Here, we show that WNT-inducible secreted protein-1 (Wisp-1), a matricellular protein that promotes angiogenesis in cancers as well as cell survival in isolated cardiac myocytes and neurons, is a target of HDACs. Further, Wisp-1 transcription is regulated by HDACs and can be modified by the HDAC inhibitor, suberanilohydroxamic acid (SAHA/vorinostat), after MI injury. We observe that, at 7 days after MI, Wisp-1 is elevated 3-fold greater in the border zone of infarction in mice that experience an MI injury and are injected daily with SAHA, relative to MI alone. Additionally, human coronary artery endothelial cells (HCAECs) produce WISP-1 and are responsive to autocrine WISP-1-mediated signaling, which functionally promotes their proangiogenic behavior. Altering endogenous expression of WISP-1 in HCAECs directly impacts their network density in vitro. Therapeutic interventions after a heart attack define the extent of infarct injury, cell survival, and overall prognosis. Our studies shown here identify a potentially novel cardiac angiokine, Wisp-1, that may contribute to beneficial post-MI treatment modalities. PMID- 29467325 TI - Lipid abnormalities in atopic skin are driven by type 2 cytokines. AB - Lipids in the stratum corneum of atopic dermatitis (AD) patients differ substantially in composition from healthy subjects. We hypothesized that hyperactivated type 2 immune response alters AD skin lipid metabolism. We have analyzed stratum corneum lipids from nonlesional and lesional skin of AD subjects and IL-13 skin-specific Tg mice. We also directly examined the effects of IL-4/IL 13 on human keratinocytes in vitro. Mass spectrometric analysis of lesional stratum corneum from AD subjects and IL-13 Tg mice revealed an increased proportion of short-chain (N-14:0 to N-24:0) NS ceramides, sphingomyelins, and 14:0-22:0 lysophosphatidylcholines (14:0-22:0 LPC) with a simultaneous decline in the proportion of corresponding long-chain species (N-26:0 to N-32:0 sphingolipids and 24:0-30:0 LPC) when compared with healthy controls. An increase in short-chain LPC species was also observed in nonlesional AD skin. Similar changes were observed in IL-4/IL-13-driven responses in Ca2+-differentiated human keratinocytes in vitro, all being blocked by STAT6 silencing with siRNA. RNA sequencing analysis performed on stratum corneum of AD as compared with healthy subjects identified decreased expression of fatty acid elongases ELOVL3 and ELOVL6 that contributed to observed changes in atopic skin lipids. IL-4/IL-13 also inhibited ELOVL3 and ELOVL6 expression in keratinocyte cultures in a STAT6 dependent manner. Downregulation of ELOVL3/ELOVL6 expression in keratinocytes by siRNA decreased the proportion of long-chain fatty acids globally and in sphingolipids. Thus, our data strongly support the pathogenic role of type 2 immune activation in AD skin lipid metabolism. PMID- 29467327 TI - Talking TOR: a conversation with Joe Heitman and Rao Movva. PMID- 29467326 TI - Loss of epigenetic regulator TET2 and oncogenic KIT regulate myeloid cell transformation via PI3K pathway. AB - Mutations in KIT and TET2 are associated with myeloid malignancies. We show that loss of TET2-induced PI3K activation and -increased proliferation is rescued by targeting the p110alpha/delta subunits of PI3K. RNA-Seq revealed a hyperactive c Myc signature in Tet2-/- cells, which is normalized by inhibiting PI3K signaling. Loss of TET2 impairs the maturation of myeloid lineage-derived mast cells by dysregulating the expression of Mitf and Cebpa, which is restored by low-dose ascorbic acid and 5-azacytidine. Utilizing a mouse model in which the loss of TET2 precedes the expression of oncogenic Kit, similar to the human disease, results in the development of a non-mast cell lineage neoplasm (AHNMD), which is responsive to PI3K inhibition. Thus, therapeutic approaches involving hypomethylating agents, ascorbic acid, and isoform-specific PI3K inhibitors are likely to be useful for treating patients with TET2 and KIT mutations. PMID- 29467328 TI - Allograft dendritic cell p40 homodimers activate donor-reactive memory CD8+ T cells. AB - Recipient endogenous memory T cells with donor reactivity pose an important barrier to successful transplantation and costimulatory blockade-induced graft tolerance. Longer ischemic storage times prior to organ transplantation increase early posttransplant inflammation and negatively impact early graft function and long-term graft outcome. Little is known about the mechanisms enhancing endogenous memory T cell activation to mediate tissue injury within the increased inflammatory environment of allografts subjected to prolonged cold ischemic storage (CIS). Endogenous memory CD4+ and CD8+ T cell activation is markedly increased within complete MHC-mismatched cardiac allografts subjected to prolonged versus minimal CIS, and the memory CD8+ T cells directly mediate CTLA 4Ig-resistant allograft rejection. Memory CD8+ T cell activation within allografts subjected to prolonged CIS requires memory CD4+ T cell stimulation of graft DCs to produce p40 homodimers, but not IL-12 p40/p35 heterodimers. Targeting p40 abrogates memory CD8+ T cell proliferation within the allografts and their ability to mediate CTLA-4Ig-resistant allograft rejection. These findings indicate a critical role for memory CD4+ T cell-graft DC interactions to increase the intensity of endogenous memory CD8+ T cell activation needed to mediate rejection of higher-risk allografts subjected to increased CIS. PMID- 29467329 TI - T cell developmental arrest in former premature infants increases risk of respiratory morbidity later in infancy. AB - The inverse relationship between gestational age at birth and postviral respiratory morbidity suggests that infants born preterm (PT) may miss a critical developmental window of T cell maturation. Despite a continued increase in younger PT survivors with respiratory complications, we have limited understanding of normal human fetal T cell maturation, how ex utero development in premature infants may interrupt normal T cell development, and whether T cell development has an effect on infant outcomes. In our longitudinal cohort of 157 infants born between 23 and 42 weeks of gestation, we identified differences in T cells present at birth that were dependent on gestational age and differences in postnatal T cell development that predicted respiratory outcome at 1 year of age. We show that naive CD4+ T cells shift from a CD31-TNF-alpha+ bias in mid gestation to a CD31+IL-8+ predominance by term gestation. Former PT infants discharged with CD31+IL8+CD4+ T cells below a range similar to that of full-term born infants were at an over 3.5-fold higher risk for respiratory complications after NICU discharge. This study is the first to our knowledge to identify a pattern of normal functional T cell development in later gestation and to associate abnormal T cell development with health outcomes in infants. PMID- 29467330 TI - Inducible podocyte-specific deletion of CTCF drives progressive kidney disease and bone abnormalities. AB - Progressive chronic kidney diseases (CKDs) are on the rise worldwide. However, the sequence of events resulting in CKD progression remain poorly understood. Animal models of CKD exploring these issues are confounded by systemic toxicities or surgical interventions to acutely induce kidney injury. Here we report the generation of a CKD mouse model through the inducible podocyte-specific ablation of an essential endogenous molecule, the chromatin structure regulator CCCTC binding factor (CTCF), which leads to rapid podocyte loss (iCTCFpod-/-). As a consequence, iCTCFpod-/- mice develop severe progressive albuminuria, hyperlipidemia, hypoalbuminemia, and impairment of renal function, and die within 8-10 weeks. CKD progression in iCTCFpod-/- mice leads to high serum phosphate and elevations in fibroblast growth factor 23 (FGF23) and parathyroid hormone that rapidly cause bone mineralization defects, increased bone resorption, and bone loss. Dissection of the timeline leading to glomerular pathology in this CKD model led to the surprising observation that podocyte ablation and the resulting glomerular filter destruction is sufficient to drive progressive CKD and osteodystrophy in the absence of interstitial fibrosis. This work introduces an animal model with significant advantages for the study of CKD progression, and it highlights the need for podocyte-protective strategies for future kidney therapeutics.

Our goal was to establish that PTEN loss promotes SMC dedifferentiation and pathological vascular remodeling in human atherosclerotic coronary arteries and nonatherosclerotic coronary arteries exposed to continuous-flow left ventricular assist devices (CF LVADs). Arteries were categorized as nonatherosclerotic hyperplasia (NAH), atherosclerotic hyperplasia (AH), or complex plaque (CP). NAH coronary arteries from CF-LVAD patients were compared to NAH coronaries from non-LVAD patients. Intimal PTEN and SMC contractile protein expression was reduced compared with the media in arteries with NAH, AH, or CP. Compared with NAH, PTEN and SMC contractile protein expression was reduced in the media and intima of arteries with AH and CP. NAH arteries from CF-LVAD patients showed marked vascular remodeling and reduced PTEN and alpha-smooth muscle actin (alphaSMA) in medial SMCs compared with arteries from non-LVAD patients; this correlated with increased medial collagen deposition. Mechanistically, compared with ApoE-/- mice, SMC-specific PTEN-null/ApoE-/- double-knockout mice exhibited accelerated atherosclerosis progression and increased vascular fibrosis. By microarray and validated quantitative RT-PCR analysis, SMC PTEN deficiency promotes a global upregulation of proinflammatory and profibrotic genes. We propose that PTEN is an antiinflammatory, antifibrotic target that functions to maintain SMC differentiation. SMC loss of PTEN results in pathological vascular remodeling of human arteries. PMID- 29467332 TI - Chronic beta2AR stimulation limits CFTR activation in human airway epithelia. AB - Traditional pulmonary therapies for cystic fibrosis (CF) target the downstream effects of CF transmembrane conductance regulator (CFTR) dysfunction (the cause of CF). Use of one such therapy, beta-adrenergic bronchodilators (such as albuterol), is nearly universal for airway clearance. Conversely, novel modulator therapies restore function to select mutant CFTR proteins, offering a disease modifying treatment. Recent trials of modulators targeting F508del-CFTR, the most common CFTR mutation, suggest that chronic beta-agonist use may undermine clinical modulator benefits. We therefore sought to understand the impact of chronic or excess beta-agonist exposure on CFTR activation in human airway epithelium. The present studies demonstrate a greater than 60% reduction in both wild-type and modulator-corrected F508del-CFTR activation following chronic exposure to short- and long-acting beta-agonists. This reduction was due to reduced cellular generation of cAMP downstream of the beta-2 adrenergic receptor G protein complex. Our results point towards a posttranscriptional reduction in adenylyl cyclase function as the mechanism of impaired CFTR activation produced by prolonged beta-agonist exposure. beta-Agonist-induced CFTR dysfunction was sufficient to abrogate VX809/VX770 modulation of F508del-CFTR in vitro. Understanding the clinical relevance of our observations is critical for CF patients using these drugs, and for investigators to inform future CFTR modulator drug trials. PMID- 29467333 TI - CHD7 represses the retinoic acid synthesis enzyme ALDH1A3 during inner ear development. AB - CHD7, an ATP-dependent chromatin remodeler, is disrupted in CHARGE syndrome, an autosomal dominant disorder characterized by variably penetrant abnormalities in craniofacial, cardiac, and nervous system tissues. The inner ear is uniquely sensitive to CHD7 levels and is the most commonly affected organ in individuals with CHARGE. Interestingly, upregulation or downregulation of retinoic acid (RA) signaling during embryogenesis also leads to developmental defects similar to those in CHARGE syndrome, suggesting that CHD7 and RA may have common target genes or signaling pathways. Here, we tested three separate potential mechanisms for CHD7 and RA interaction: (a) direct binding of CHD7 with RA receptors, (b) regulation of CHD7 levels by RA, and (c) CHD7 binding and regulation of RA related genes. We show that CHD7 directly regulates expression of Aldh1a3, the gene encoding the RA synthetic enzyme ALDH1A3 and that loss of Aldh1a3 partially rescues Chd7 mutant mouse inner ear defects. Together, these studies indicate that ALDH1A3 acts with CHD7 in a common genetic pathway to regulate inner ear development, providing insights into how CHD7 and RA regulate gene expression and morphogenesis in the developing embryo. PMID- 29467334 TI - A specific phosphorylation regulates the protective role of alphaA-crystallin in diabetes. AB - Neurodegeneration is a central aspect of the early stages of diabetic retinopathy, the primary ocular complication associated with diabetes. While progress has been made to improve the vascular perturbations associated with diabetic retinopathy, there are still no treatment options to counteract the neuroretinal degeneration associated with diabetes. Our previous work suggested that the molecular chaperones alpha-crystallins could be involved in the pathophysiology of diabetic retinopathy; however, the role and regulation of alpha-crystallins remained unknown. In the present study, we demonstrated the neuroprotective role of alphaA-crystallin during diabetes and its regulation by its phosphorylation on residue 148. We further characterized the dual role of alphaA-crystallin in neurons and glia, its essential role for neuronal survival, and its direct dependence on phosphorylation on this residue. These findings support further evaluation of alphaA-crystallin as a treatment option to promote neuron survival in diabetic retinopathy and neurodegenerative diseases in general. PMID- 29467335 TI - Apolipoproteins E and CIII interact to regulate HDL metabolism and coronary heart disease risk. AB - BACKGROUND: Subspecies of HDL contain apolipoprotein E (apoE) and/or apoCIII. Both proteins have properties that could affect HDL metabolism. The relation between HDL metabolism and risk of coronary heart disease (CHD) is not well understood. METHODS: Eighteen participants were given a bolus infusion of [D3]L leucine to label endogenous proteins on HDL. HDL was separated into subspecies containing apoE and/or apoCIII and then into 4 sizes. Metabolic rates for apoA-I in HDL subspecies and sizes were determined by interactive modeling. The concentrations of apoE in HDL that contain or lack apoCIII were measured in a prospective study in Denmark including 1,949 incident CHD cases during 9 years. RESULTS: HDL containing apoE but not apoCIII is disproportionately secreted into the circulation, actively expands while circulating, and is quickly cleared. These are key metabolic steps in reverse cholesterol transport, which may protect against atherosclerosis. ApoCIII on HDL strongly attenuates these metabolic actions of HDL apoE. In the epidemiological study, the relation between HDL apoE concentration and CHD significantly differed depending on whether apoCIII was present. HDL apoE was associated significantly with lower risk of CHD only in the HDL subspecies lacking apoCIII. CONCLUSIONS: ApoE and apoCIII on HDL interact to affect metabolism and CHD. ApoE promotes metabolic steps in reverse cholesterol transport and is associated with lower risk of CHD. ApoCIII, when coexisting with apoE on HDL, abolishes these benefits. Therefore, differences in metabolism of HDL subspecies pertaining to reverse cholesterol transport are reflected in differences in association with CHD.

PMID- 29467336 TI - Frameshift events predict anti-PD-1/L1 response in head and neck cancer. AB - Programmed cell death protein 1 (PD-1) inhibitors have efficacy in treating squamous cell carcinoma of the head and neck (SCCHN), but objective response rates are low. PD-1 ligand (PD-L1) expression alone is not considered a robust predictor of response and additional biomarkers are needed. This 3-year observational cohort followed 126 SCCHN patients treated with anti-PD-1/L1 therapy. Prior to treatment, 81 (64%) had targeted massively parallel tumor sequencing. Of these, 42 (52%) underwent fluorescence-activated cell sorting and PD-L1 immunohistochemistry for tumor immunoprofiling. Six (5%) complete responses (CRs) and 11 (9%) partial responses (PRs) were observed. Those treated with prior chemotherapy (98, 78%) versus only surgery and/or radiation had longer overall survival (OS) (10 vs. 3 months, P = 0.02). Smokers had a higher total mutational burden (TMB) (P = 0.01). Virus-positive patients had a lower TMB (P < 0.01) and improved OS (P = 0.02). Among virus-negative responders, NOTCH1 and SMARCA4 were more frequently mutated and frameshift events in tumor suppressor genes occurred more frequently (P = 0.03). Higher TMB and CD8+ T cell infiltrates predicted anti PD-1/L1 benefit (P < 0.01, P < 0.01, respectively) among virus-negative tumors. TIM-3/LAG-3 coexpression with PD-1 was higher on T cells among nonresponders (P = 0.03 and 0.02, respectively). Somatic frameshift events in tumor suppressor genes and higher TMB among virus-negative SCCHN tumors predict anti-PD-1/L1 response. PMID- 29467337 TI - Nitric oxide-sensitive guanylyl cyclase stimulation improves experimental heart failure with preserved ejection fraction. AB - Heart failure with preserved ejection fraction (HFpEF) can arise from cardiac and vascular remodeling processes following long-lasting hypertension. Efficacy of common HF therapeutics is unsatisfactory in HFpEF. Evidence suggests that stimulators of the nitric oxide-sensitive soluble guanylyl cyclase (NOsGC) could be of use here. We aimed to characterize the complex cardiovascular effects of NOsGC stimulation using NO-independent stimulator BAY 41-8543 in a double transgenic rat (dTGR) model of HFpEF. We show a drastically improved survival rate of treated dTGR. We observed less cardiac fibrosis, macrophage infiltration, and gap junction remodeling in treated dTGR. Microarray analysis revealed that treatment of dTGR corrected the dysregulateion of cardiac genes associated with fibrosis, inflammation, apoptosis, oxidative stress, and ion channel function toward an expression profile similar to healthy controls. Treatment reduced systemic blood pressure levels and improved endothelium-dependent vasorelaxation of resistance vessels. Further comprehensive in vivo phenotyping showed an improved diastolic cardiac function, improved hemodynamics, and less susceptibility to ventricular arrhythmias. Short-term BAY 41-8543 application in isolated untreated transgenic hearts with structural remodeling significantly reduced the occurrence of ventricular arrhythmias, suggesting a direct nongenomic role of NOsGC stimulation on excitation. Thus, NOsGC stimulation was highly effective in improving several HFpEF facets in this animal model, underscoring its potential value for patients. PMID- 29467339 TI - Photoreactivities of the Antiseptics Dehydroacetic Acid and Sodium Dehydroacetate Used in Cosmetics. AB - Dehydroacetic acid (1) was found to induce photoisomerization, converting aldrin (3) and dieldrin (4) into photoaldrin (5) and photodieldrin (6), respectively, not only when irradiated with artificial light at wavelengths longer than 290 nm in air but also when exposed to sunlight in air. By contrast, sodium dehydroacetate (2) induced both photoisomerization, primarily converting 3 to 5 and photoepoxidation, partially forming 6. Thus, because 2 is usually used as a water-soluble antiseptic, photo-erethism might occur due to the isomerization and epoxidation properties of this compound. The difference between the photoreactivity of 1 and that of 2 might be attributed to the spin density of the odd electron on the carbon atom in the respective radicals that were formed after photo-excited 1 and 2 caused H-abstraction. PMID- 29467338 TI - TCR-mimic bispecific antibodies targeting LMP2A show potent activity against EBV malignancies. AB - EBV infection is associated with a number of malignancies of clinical unmet need, including Hodgkin lymphoma, nasopharyngeal carcinoma, gastric cancer, and posttransplant lymphoproliferative disease (PTLD), all of which express the EBV protein latent membrane protein 2A (LMP2A), an antigen that is difficult to target by conventional antibody approaches. To overcome this, we utilized phage display technology and a structure-guided selection strategy to generate human T cell receptor-like (TCR-like) monoclonal antibodies with exquisite specificity for the LMP2A-derived nonamer peptide, C426LGGLLTMV434 (CLG), as presented on HLA A*02:01. Our lead construct, clone 38, closely mimics the native binding mode of a TCR, recognizing residues at position P3-P8 of the CLG peptide. To enhance antitumor potency, we constructed dimeric T cell engaging bispecific antibodies (DiBsAb) of clone 38 and an affinity-matured version clone 38-2. Both DiBsAb showed potent antitumor properties in vitro and in immunodeficient mice implanted with EBV transformed B lymphoblastoid cell lines and human T cell effectors. Clone 38 DiBsAb showed a stronger safety profile compared with its affinity matured variant, with no activity against EBV- tumor cell lines and a panel of normal tissues, and was less cross-reactive against HLA-A*02:01 cells pulsed with a panel of CLG-like peptides predicted from a proteomic analysis. Clone 38 was also shown to recognize the CLG peptide on other HLA-A*02 suballeles, including HLA-A*02:02, HLA-A*02:04, and HLA-A*02:06, allowing for its potential use in additional populations. Clone 38 DiBsAb is a lead candidate to treat EBV malignancies with one of the strongest safety profiles documented for TCR-like mAbs. PMID- 29467340 TI - Saltatory Conduction as an Electrostatic Compressional Wave in the Axoplasm. AB - Saltatory conduction is an essential phenomenon to facilitate the fast conduction in myelinated nerves. The conventional conductive models assumed electric circuits with local current along the axonal membrane to explain the nerve conduction in unmyelinated nerves. However, whether such models with local current can be also applied to the saltatory conduction in myelinated nerves is unknown. In this report, I propose a new model of saltatory conduction by focusing on the behavior of electric charges in the axoplasm, not limited to the membrane. In myelinated nerves, because of the large internodal length and the low ion channel density in the internodal segment, the whole cross-section of the internodal axoplasm would contribute to the signal conduction. Because the conducted signals originate from the sodium ion influx through the voltage-gated sodium (NaV) channel at the Ranvier's nodes, an individual conducted signal can be described as a single electrostatic compressional wave of positive charges in the internodal axoplasm. Based on this model, the total number of NaV channels in one Ranvier's node would regulate the strength of the wave. Also, the internodal length would be important for the faster conduction in larger myelinated axons. Based on the linear relationships between axonal diameter, internodal length, and conduction velocity, the internodal length would be inversely proportional to the ratio of the transmitted overall wave strength at a Ranvier's node to the original strength at the proximal adjacent node. This new mathematical model may have wide applicability and usability for the conduction in myelinated nerves.

AB - Retracted Review article: Nucleophagy in Human Disease: Beyond the Physiological Role. [Tohoku J. Exp. Med., 2018, 244 (1), 75-81. doi: 10.1620/tjem.244.75.]The above Review article was published online on January 27, 2018. Soon after its publication (on February 1, 2018), Dr. Nian Fu and Prof. Linxi Chen informed the Editor-in-Chief, The Tohoku Journal of Experimental Medicine (TJEM), about serious violation of publication ethics. Indeed, Dr. Nian Fu and Prof. Linxi Chen were astonished to find their names as coauthors of this Review article, because they were not involved in the submission process of this Review article and they do not know any of other coauthors. In addition, the Review article is similar to their unpublished manuscript.After a thorough investigation in accordance with the recommendations of the Committee on Publication Ethics (COPE), the Editor-in Chief of TJEM decided to retract this Review article. The reasons for Retraction are summarized below: forged authors and an unexpected case of plagiarism.Forged authors: Dr. Nian Fu and Prof. Linxi Chen were added as co-authors of the Review article without their knowledge. In fact, the signature provided by Prof. Linxi Chen is apparently different from the signature of a coauthor, named Linxi Chen, on the AUTHORS' RESPONSIBILITY FORM, provided by the corresponding author of the Review article. More critically, the signature provided by Dr. Nian Fu is completely different from the signature of Nian Fu, because the Chinese characters are different between the two signatures. In addition, the replies from three authors (Ming Zhou, Hongwen Ji and Yong Xia) clearly indicate that they misunderstand the identity of Dr. Nina Fu. We also attempted to contact two authors, named Nian Fu and Linxi Chen, via e-mail. As expected, the forged authors did not respond to our inquiries, despite that their e-mail addresses appear to be active.An unexpected case of plagiarism: This Review article is similar to the unpublished manuscript prepared by Dr. Nian Fu and Prof. Linxi Chen. Moreover, two figures used in the Review article are identical to the preliminary figures of their unpublished manuscript. According to Dr. Nian Fu, a local agency for language editing had transferred their unpublished manuscript to a third party. Unfortunately, the check system of TJEM is not effective for plagiarism of unpublished materials. We believe that the corresponding author of the Review article included the names of the original two authors to avoid the criticism of plagiarism. Eventually, the corresponding author agreed to retract the Review article.We apologize for any inconvenience caused by this retraction to readers. We also hope that the publication of the plagiarized Review article will not trouble Dr. Nian Fu and Prof. Linxi Chen too much.

AB - Glucose promotes insulin secretion primarily via its metabolism and the production of metabolic coupling factors in beta-cells. The activation of AMP activated protein kinase (AMPK), an energy sensor, results in a decrease in insulin secretion from beta-cells, but its mechanism remains largely unknown. Berberine, an oral anti-diabetic drug, has been shown to activate AMPK in multiple peripheral tissues. Here, we examined the effects of berberine and AMPK activation on insulin secretion and glucose oxidation in rat islets. Our results showed that berberine inhibited glucose-stimulated insulin secretion from rat islets with AMPK activation. When glucose concentration was elevated to 25 mmol/L, the inhibitory action of berberine on insulin secretion disappeared. Furthermore, berberine significantly decreased oxygen consumption rate (OCR) and ATP production induced by high glucose in rat islets. Although adenovirus mediated overexpression of constituent-activated AMPK markedly decreased GSIS and OCR in rat islets, the inhibition of AMPK by compound C did not reverse berberine suppressed OCR. In addition, berberine attenuated glucose-stimulated expression of fatty acid synthase. These results indicate that berberine-mediated deceleration of glucose oxidation is tightly link to the decreased insulin secretion in islets independent of AMPK activation and inhibition of fatty acid synthesis may also contribute to the effect of berberine on insulin secretion. PMID- 29467345 TI - Ligustrazine Enhances the Hypnotic and Analgesic Effect of Ketamine in Mice. AB - The purpose of this study was to determine the effects of different concentrations of ligustrazine, an extract from Chinese herb, on ketamine requirement for hypnosis and analgesia in mice. In the hypnotic response study, mice were randomly allocated to receive saline or ligustrazine at 10, 20, 40, 80 or 160 mg.kg-1 by intraperitoneal injection. Ketamine was administrated 15 min after ligustrazine injection. The hypnotic response was determined by assessing loss of the righting reflex (LORR) after ketamine injection. The dose of ketamine was determined by modified Dixon's up-and-down method in each group. In the analgesia study, different doses of ligustrazine were administrated 15 min before 50 mg.kg-1 ketamine injection. The analgesia effects (pain threshold) were determined by heat radiation-induced tail-flick latency and evaluated before ligustrazine administration or 5, 15, 30 and 60 min after ketamine administration. The ED50 [95% confidence interval (CI)] for hypnosis induced by ketamine was 54.1 (44.8, 65.3) mg.kg-1. Ligustrazine dose-dependently decreased the ED50 for ketamine to induce hypnosis, which was [31.6 (26.2, 38.1)] mg.kg-1 with the addition of 80 mg.kg-1 ligustrazine and [27.7 (22.6, 33.7)] mg.kg-1 with the addition of 160 mg.kg-1 ligustrazine, respectively (p<0.05). Ligustrazine at 160 mg.kg-1 also increased pain threshold in the presence of ketamine. Ligustrazine enhanced the hypnotic effect of ketamine in a dose-dependent manner. Ligustrazine at a large dose also increased the analgesic effect of ketamine. PMID- 29467346 TI - Absorption and metabolism of orally administered collagen hydrolysates evaluated by the vascularly perfused rat intestine and liver in situ. AB - A number of studies have shown that oral administration of collagen hydrolysate (CH) results in the absorption of di- and tri-peptides. In order to understand the dynamics of CH absorption and metabolism, molecular profiles of hydroxyproline (Hyp) and Hyp-containing peptides (HCPs) were analyzed by in situ perfusion of rat intestine and liver. The total amount of absorbed HCPs during 1 h of perfusion was 16.6 MUmol, which was significantly higher than that of free Hyp (6.6 MUmol). In addition, HCPs were also reliably detected in hepatic perfusate at the level higher than free Hyp. Thus, the results demonstrated that CH is absorbed predominantly as peptides, which subsequently enter systemic circulation. Size exclusion chromatography showed that perfusates include significant amount of HCPs larger than tripeptides, leading us to analyze these peptides in detail. Mass spectrometric analysis of intestinal perfusate finally identified three CH-derived peptides, which are surprisingly large as food derived circulating peptides. Peptide quantitation by liquid chromatography tandem mass spectrometry (LC-MS/MS) revealed that di- and tri-peptides, which are previously identified as major peptides in circulating blood, comprise only a part of HCPs in intestinal and liver perfusate. Finally, analysis of portal vein blood revealed that the larger peptides, such as pentadecapeptide identified in this study, could be absorbed in vivo. Taken all together, this study showed that peptides which are larger than tripeptide could reach to the circulation system after administration of CH, revealing previously unknown dynamics of absorption of CH. PMID- 29467347 TI - A cell-based interferon-tau assay with an interferon-stimulated gene 15 promoter. AB - Interferon-tau (IFNT) is known as an early pregnancy recognition signal in ruminants. An accurate and convenient IFNT detection system is desirable for the diagnosis of endometrial and trophoblastic functions, including gestation status, in cows. The aim of this study was to develop a new cell-based assay, which involved the stable introduction of an interferon-stimulated gene promoter to a luciferase reporter system. The reactivity of four interferon-stimulated genes to IFNT in Madin-Darby bovine kidney (MDBK) cells was confirmed using reverse transcription-quantitative PCR. The upstream region of the interferon-stimulated gene 15 ubiquitin-like modifier (ISG15) gene as the promoter of the reporter gene, which is more responsive to IFNT and other IFNs, was determined using the luciferase assay. The reporter gene with the ISG15 upstream region was stably transfected into MDBK cells using the PiggyBac vector system; this cell line responded to type I IFNs in a dose-dependent manner. Because of its convenience, this cell line is suitable for the quantification of IFNT as well as other type I IFNs activities. PMID- 29467348 TI - Combination of a cryosectioning method and section scanning electron microscopy for immuno-scanning electron microscopy. AB - We describe a novel immuno-scanning electron microscopy (SEM) technique that combines both Tokuyasu's cryosectioning and section SEM methods. In this technique, semithin cryosections, cut according to the Tokuyasu method, were adhered to glass microscope slides, immunostained for bio-molecules of interest and observed by confocal laser scanning microscopy. The same sections were subsequently embedded in epoxy resin and ultrathin sections were cut on an ultramicrotome. These were then observed by SEM using a backscattered electron detector. Correlation between immunofluorescence and SEM images was performed in the same area of the cryosection. Immuno-SEM was also performed using a FluoroNanogold-labeled secondary antibody. This novel immuno-SEM method can provide ultrastructural information of cell organelles in relation to associated molecules, such as Golgi- and ER-associated proteins. This novel immuno-SEM technique has the potential to be widely used.

AB - Severe fever with thrombocytopenia syndrome phlebovirus (SFTSV) is a newly emerged phlebovirus identified in China, Japan, and South Korea. Phlebovirus glycoproteins (GP) play a key role in targeting viral structural components to the budding compartments in the ER-Golgi intermediate compartment (ERGIC) and Golgi complex. However, the role of SFTSV GP in targeting structural proteins to the ERGIC and Golgi complex remains unresolved. In this study, we show that SFTSV GP plays a significant role in targeting RNA-dependent RNA polymerase (L) and nucleocapsid protein (NP) to the budding sites. Confocal microscopy was used to investigate the subcellular localization of SFTSV structural proteins. In SFTSV infected cells, GP and L localized to the ER, ERGIC and Golgi complex, whereas NP localized to the ERGIC and Golgi complex. In addition, GP colocalized with L and NP in infected cells. In cells singly transfected with GP, L or NP, GP localized to the same subcellular compartments as in infected cells. However, L or NP alone did not localize to the ER, ERGIC, or Golgi complex. Cotransfection experiments showed that GP altered the localization of L to the ERGIC and Golgi complex but not that of NP. Interestingly, plasmid-expressed NP fused with a hemagglutinin tag localized to the ERGIC and Golgi complex when expressed in SFTSV-infected cells and colocalised with GP, suggesting that GP plays a role in the subcellular localization of L and NP in infected cells. Thus, the SFTSV structural components start to assemble at the ERGIC to Golgi complex. GP is required for transporting L and NP to the ERGIC and Golgi complex. In addition, targeting of NP requires interaction with other factors besides GP. PMID- 29467350 TI - Influence of nitrous oxide on granule cell migration in the dentate gyrus of the neonatal rat. AB - For several decades, the neurotoxicities of anesthetics to the developing brain have been reported by many researchers focusing on various phenomena such as apoptosis, neurodegeneration, electrophysiological aberrations, and behavioral abnormalities. According to these reports, signals via N-methyl-D-aspartate receptors (NMDA-r) and/or gamma-aminobutyric acid type A receptors (GABAA-r) are implicated in the anesthetic neurotoxicity. On the other hand, during brain development, NMDA-r and GABAA-r are also recognized to play primary roles in neural cell migration. Therefore, anesthetics exposed in this period may influence the neural cell migration of neonates, and increase the number of hilar ectopic granule cells, which are reported to be a cause of continuous neurological deficits. To examine this hypothesis, we investigated immunohistochemically granule cell distribution in the hippocampal dentate gyrus of Wistar/ST rats after nitrous oxide (N2O) exposure. At postnatal day (P) 6, 5 bromo-2'-deoxyuridine (BrdU) was administered to label newly generated cells. Then, rats were divided into groups (n = 6 each group), exposed to 50% N2O at P7, and evaluated at P21. As a result, we found that ectopic ratios (ratio of hilar/total granule cells generated at P6) were decreased in rats at P21 compared with those at P7, and increased in N2O exposed rats for over 120 min compared with the other groups. These results suggest that 50% N2O exposure for over 120 min increases the ratios of ectopic granule cells in the rat dentate gyrus. PMID- 29467351 TI - Short and long photoperiods differentially exacerbate corticosterone-induced physical and psychological symptoms in mice. AB - Circadian disruption affects the pathogenesis and development of various diseases. Depression is one of the most common diseases that relate to circadian rhythm. In this study, we analyzed the effects of daily light/dark (LD) conditions on depression and other symptoms, and also analyzed the mixed effects of LD conditions and corticosterone treatment. Male adult C57BL/6 mice were treated with corticosterone in a normal LD cycle of 12 hours light and 12 hours dark (LD12 : 12), short day conditions of 6 hours light and 18 hours dark (LD6 : 18), or long day conditions of 21 hours light and 3 hours dark (LD21 : 3). The activity rhythms of mice in aberrant LD conditions were entrained within 2 weeks. After 6 weeks of exposure, several behavioral tests were conducted. Corticosterone induced body weight gain and depression-like symptoms. The short or long LD conditions had little effect on vehicle-treated mice behavior. However, the aberrant LD conditions exacerbated the corticosterone-induced symptoms. Mice treated with corticosterone in LD6 : 18 showed exacerbated depression-like symptoms in a novelty suppressed feeding test. On the other hand, LD21 : 3 did not show any effects on mood, but enhanced corticosterone-induced body weight gain. These results indicated that aberrant LD conditions could act as an exacerbating factor for corticosterone-induced symptoms, and that short and long photoperiods induce different psychological and physiological changes. This corticosterone + aberrant LD model could be a useful animal model for investigating the effect of LD conditions on depression, obesity, and other symptoms in stressful circumstances. PMID- 29467353 TI - Can Tolvaptan Protect Renal Function in the Early Postoperative Period of Cardiac Surgery? - Results of a Single-Center Randomized Controlled Study. AB - BACKGROUND: Oral administration of tolvaptan, a vasopressin V2receptor antagonist, significantly reduces deterioration of renal function, which has recently been highlighted as an exacerbating factor for adverse events in patients with acute heart failure. In the present study we tested the hypothesis that concomitant administration of tolvaptan with a conventional diuretic is beneficial for perioperative body fluid management in patients who have undergone cardiac surgery.Methods and Results:In all, 280 patients who underwent cardiac surgery were prospectively randomized to concomitant treatment with tolvaptan and a conventional diuretic (tolvaptan group; 147 patients) or treatment with a conventional diuretic alone (control group; 133 patients). Groups were compared in terms of the time required to restore preoperative body weight and the incidence of worsening renal function (WRF), defined as an increase in the serum creatinine level >=0.3 mg/dL. The time required to restore preoperative body weight was significantly shorter in the tolvaptan than control group (mean [+/ SD] 3.97+/-1.95 vs. 5.02+/-2.83 days, respectively; P<0.001). The incidence of WRF was significantly lower in the tolvaptan than control group (n=11 [7.5%] vs. n=25 [18.8%], respectively; P=0.011). CONCLUSIONS: Administration of tolvaptan with conventional diuretics in the early postoperative period after cardiac surgery could be beneficial in maintaining urine output without affecting renal function and may thus help avoid WRF. PMID- 29467354 TI - High Signal Intensity on T2-Weighted Cardiovascular Magnetic Resonance Imaging Predicts Life-Threatening Arrhythmic Events in Hypertrophic Cardiomyopathy Patients. AB - BACKGROUND: The prognostic value of high signal intensity on T2-weighted cardiovascular magnetic resonance imaging (T2 high signal) in hypertrophic cardiomyopathy (HCM) patients in a single-center cohort was investigated.Methods and Results:A total of 237 HCM patients (median age, 62 years; 143 male) underwent T2-weighted, cine and late gadolinium enhancement (LGE) imaging, and were followed (median duration, 3.4 years) for life-threatening arrhythmic events. The clinical and magnetic resonance imaging characteristics were extracted, and predictors of life-threatening arrhythmic events were assessed on multivariate analysis. LGE was present in 180 patients (75.9%). Median LGE score was 3 in a left ventricle 17-segment model. T2 high signal was present in 49 patients (20.7%). The annual events rate was significantly higher in patients with extensive LGE (score >=4) than in those without (3.0%/year vs. 0.5%/year, P=0.011). On multivariate analysis, extensive LGE (hazard ratio, 5.650; 95% CI: 1.263-25.000, P=0.024) as an independent predictor for life-threatening arrhythmic events. In patients with extensive LGE, the annual events rate was significantly higher in patients with T2 high signal than in those without (5.8%/year vs. 0.9%/year, P=0.008). CONCLUSIONS: Extensive LGE was an independent predictor of life-threatening arrhythmic events in HCM patients. Furthermore, T2 high signal is useful for the risk stratification of serious arrhythmic events in patients with extensive LGE.

AB - The common marmoset (Callithrix jacchus) is a nonhuman primate that is used for preclinical research on stem cell transplantation therapies due to its similarity to human beings as well as its small size, enabling researchers to perform experiments without preparing a large number of cells. In this study, we developed a marmoset hepatic fibrosis model for regenerative medicine research. Six female marmosets aged 4-6 years were administered thioacetamide (TAA) at a dose of 2.5-40 mg/kg two or three times a week. Hepatic fibrosis was assessed by liver biopsy when blood chemistry indicated liver damage. Administration of TAA increased total bile acid, aspartate aminotransferase, and total bilirubin and decreased serum albumin levels. Following more than 11 weeks of continuous injection of TAA, histological analyses detected hepatic fibrosis in all animals. Type IV collagen 7S serum levels in animals with hepatic fibrosis were significantly higher than in normal animals as a possible marker of hepatic fibrosis in marmosets. Serial liver biopsies following the last administration of TAA revealed that induced fibrosis remained up to 11 weeks. The results suggest that continuous TAA administration induces persistent hepatic fibrosis in the common marmoset and this nonhuman primate hepatic fibrosis model have the possibility to evaluate the therapeutic effects of test samples to ameliorate hepatic fibrosis.

AB - BACKGROUND: Although hyponatremia predicts morbidity and mortality in acute decompensated heart failure (ADHF), hypochloremia is also independently associated with poor prognosis in ADHF. Little is known, however, about the prognostic value of serial change in serum chloride during hospitalization in ADHF patients.Methods and Results:We prospectively studied 208 ADHF survivors after discharge and divided them into 4 groups according to serum chloride on admission and at discharge: (1) persistent hypochloremia group (n=12), hypochloremia both on admission and at discharge; (2) progressive hypochloremia group (n=42), development of hypochloremia after admission; (3) improved hypochloremia group (n=14), hypochloremia only on admission; and (4) no hypochloremia group, no hypochloremia during hospitalization (n=140). During a mean follow-up period of 1.86+/-0.76 years, 20 of 208 patients had heart failure death (HFD). In a model adjusted for hyponatremia, hypochloremia both on admission and at discharge was still significantly associated with HFD. Hyponatremia, however, was not significantly associated with HFD after adjustment for hypochloremia. Patients with persistent hypochloremia (HR, 9.13; 95% CI: 2.56 32.55) and with progressive hypochloremia (HR, 4.65; 95% CI: 1.61-13.4) had a significantly greater risk of HFD than those without hypochloremia during hospitalization. CONCLUSIONS: Both persistent hypochloremia and progressive hypochloremia during hospitalization are associated with HFD in ADHF patients. PMID- 29467356 TI - Endogenous Interleukin-1beta Is Implicated in Intraplaque Hemorrhage in Apolipoprotein E Gene Null Mice. AB - BACKGROUND: Intraplaque hemorrhage (IPH) has been implicated in plaque instability and rupture in atherosclerotic lesions, although the mechanisms by which IPH progresses remain largely unknown. In this study, apolipoprotein E deficient mice with carotid artery ligation and cuff placement around the artery were used, and pro-inflammatory cytokines that are implicated in IPH were analyzed.Methods and Results:The expression of interleukin-1beta (IL-1beta) increased significantly following cuff placement compared with mice with carotid artery ligation alone. IPH occurred in the cuff-placed carotid artery following treatment with the negative control (NC) small interfering RNA (siRNA). However, the occurrence was significantly reduced in the cuff-placed carotid artery following treatment with an IL-1beta siRNA. Neovessel formation was significantly reduced in the carotid artery treated with the NC siRNA compared with that treated with IL-1beta siRNA. IL-1beta significantly inhibited the tube formation and wound healing capacities of vascular endothelial cells in vitro. Furthermore, immunostaining of matrix metalloproteinase-9 (MMP-9) significantly increased in the carotid artery treated with the NC siRNA compared with that treated with IL 1beta siRNA. CONCLUSIONS: These results suggest that endogenous IL-1beta is implicated in the progression of IPH via the inhibition of physiological angiogenesis in the atherosclerotic plaque, leading to the formation of leaky neovessels. Furthermore, the stimulation of MMP-9 expression may also contribute to the formation of leaky neovessels.

PMID- 29467359 TI - Evaluation of a Portable Doppler Ultrasound Gating Device for Fetal Cardiac MR Imaging: Initial Results at 1.5T and 3T. AB - PURPOSE: Fetal cardiac MRI has the potential to play an important role in the assessment of fetal cardiac pathologies, but it is up to now not feasible due to a missing gating method. The purpose of this work was the evaluation of Doppler ultrasound (DUS) for external fetal cardiac gating with regard to compatibility, functionality, and reliability. Preliminary results were assessed performing fetal cardiac MRI. METHODS: An MRI conditional DUS device was developed to obtain a gating signal from the fetal heart. The MRI compatibility was evaluated at 1.5T and 3T using B1 field maps and gradient echo images. The quality and sensitivity of the DUS device to detect the fetal heart motion for cardiac gating were evaluated outside the MRI room in 15 fetuses. A dynamic fetal cardiac phantom was employed to evaluate distortions of the DUS device and gating signal due to electromagnetic interferences at 1.5T and 3T. In the first in vivo experience, dynamic fetal cardiac images were acquired in four-chamber view at 1.5T and 3T in two fetuses. RESULTS: The maximum change in the B1 field and signal intensity with and without the DUS device was <6.5% for 1.5T and 3T. The sensitivity of the DUS device to detect the fetal heartbeat was 99.1%. Validation of the DUS device using the fetal cardiac phantom revealed no electromagnetic interferences at 1.5T or 3T and a high correlation to the simulated heart frequencies. Fetal cardiac cine images were successfully applied and showed good image quality. CONCLUSION: An MR conditional DUS gating device was developed and evaluated revealing safety, compatibility, and reliability for different field strengths. In a preliminary experience, the DUS device was successfully applied for in vivo fetal cardiac imaging at 1.5T and 3T. PMID- 29467360 TI - Atypical Presentation of Acute Coronary Syndrome and Importance of Wellens' Syndrome. AB - BACKGROUND Acute coronary syndrome (ACS) is a common and potentially life threatening condition encountered in emergency departments. Despite its dreaded nature, nearly one-third of ACS present without chest pain and may mislead clinicians. Additionally, Wellens' syndrome is a pre-infarction stage of significant proximal left anterior descending (LAD) artery stenosis, which can lead to extensive anterior wall myocardial infarction without timely intervention. CASE REPORT We report the case of a 74-year-old woman presenting with isolated throat pain and Wellens' pattern in the initial EKG, which prompted the proper workup and management. Subsequently, coronary angiogram revealed more than 90% occlusion of the proximal LAD artery, and a drug-eluting stent was deployed. The patient did well after the procedure and the follow-up at 2 weeks after discharge was uneventful. CONCLUSIONS This case highlights the importance of awareness of atypical presentation of ACS and importance of Wellens' syndrome. We also discuss the incidence of craniofacial symptoms of ACS, and the epidemiology, pathophysiology, management, and prognosis of Wellens' syndrome. PMID- 29467361 TI - Resveratrol Attenuates Cognitive Deficits of Traumatic Brain Injury by Activating p38 Signaling in the Brain. AB - BACKGROUND Traumatic brain injury (TBI) is characterized by cognitive deficits, which was associated with brain oxidative stress and apoptosis. Resveratrol (RSV) is an anti-apoptotic and anti-oxidative. This study aimed to investigate neuroprotective effects and involved molecular mechanisms in TBI. MATERIAL AND METHODS RSV and p38 inhibitor were administrated to TBI rats. Cognitive deficits were evaluated by Morris water maze assay. Reactive oxygen species (ROS) and apoptosis were detected in rat brains by fluorescent staining. Western blotting was used to assess the phosphorylation of p38 and the expression levels of Nrf2, HO1, and activated caspase-3. RESULTS RSV administration attenuated cognitive deficits of TBI rats. The ROS generation and apoptosis in the brain of TBI rats were suppressed by RSV treatment. Moreover, RSV treatment recovered activation of p38/Nrf2/HO1 signaling pathway. The co-administration of p38 inhibitor impaired RSV's attenuating effects on cognitive deficits, brain apoptosis, and ROS generation. CONCLUSIONS RSV attenuated cognitive deficits of TBI by inhibiting oxidative stress-mediated apoptosis via targeting p38/Nrf2 signaling.

However, it is unclear how media influences the maturational trajectories of brain regions involved in social interactions. Here we review the neural development in adolescence and show how neuroscience can provide a deeper understanding of developmental sensitivities related to adolescents' media use. We argue that adolescents are highly sensitive to acceptance and rejection through social media, and that their heightened emotional sensitivity and protracted development of reflective processing and cognitive control may make them specifically reactive to emotion-arousing media. This review illustrates how neuroscience may help understand the mutual influence of media and peers on adolescents' well-being and opinion formation. PMID- 29467363 TI - Enhancing Hi-C data resolution with deep convolutional neural network HiCPlus. AB - Although Hi-C technology is one of the most popular tools for studying 3D genome organization, due to sequencing cost, the resolution of most Hi-C datasets are coarse and cannot be used to link distal regulatory elements to their target genes. Here we develop HiCPlus, a computational approach based on deep convolutional neural network, to infer high-resolution Hi-C interaction matrices from low-resolution Hi-C data. We demonstrate that HiCPlus can impute interaction matrices highly similar to the original ones, while only using 1/16 of the original sequencing reads. We show that the models learned from one cell type can be applied to make predictions in other cell or tissue types. Our work not only provides a computational framework to enhance Hi-C data resolution but also reveals features underlying the formation of 3D chromatin interactions. PMID- 29467364 TI - Nanoscale kinetic segregation of TCR and CD45 in engaged microvilli facilitates early T cell activation. AB - T cells have a central function in mounting immune responses. However, mechanisms of their early activation by cognate antigens remain incompletely understood. Here we use live-cell multi-colour single-molecule localization microscopy to study the dynamic separation between TCRs and CD45 glycoprotein phosphatases in early cell contacts under TCR-activating and non-activating conditions. Using atomic force microscopy, we identify these cell contacts with engaged microvilli and characterize their morphology, rigidity and dynamics. Physical modelling and simulations of the imaged cell interfaces quantitatively capture the TCR-CD45 separation. Surprisingly, TCR phosphorylation negatively correlates with TCR-CD45 separation. These data support a refined kinetic-segregation model. First, kinetic-segregation occurs within seconds from TCR activation in engaged microvilli. Second, TCRs should be segregated, yet not removed too far, from CD45 for their optimal and localized activation within clusters. Our combined imaging and computational approach prove an important tool in the study of dynamic protein organization in cell interfaces. PMID- 29467365 TI - High-performance graphdiyne-based electrochemical actuators. AB - Electrochemical actuators directly converting electrical energy to mechanical energy are critically important for artificial intelligence. However, their energy transduction efficiency is always lower than 1.0% because electrode materials lack active units in microstructure, and their assembly systems can hardly express the intrinsic properties. Here, we report a molecular-scale active graphdiyne-based electrochemical actuator with a high electro-mechanical transduction efficiency of up to 6.03%, exceeding that of the best-known piezoelectric ceramic, shape memory alloy and electroactive polymer reported before, and its energy density (11.5 kJ m-3) is comparable to that of mammalian skeletal muscle (~8 kJ m-3). Meanwhile, the actuator remains responsive at frequencies from 0.1 to 30 Hz with excellent cycling stability over 100,000 cycles. Furthermore, we verify the alkene-alkyne complex transition effect responsible for the high performance through in situ sum frequency generation spectroscopy. This discovery sheds light on our understanding of actuation mechanisms and will accelerate development of smart actuators. PMID- 29467366 TI - Human Semaphorin-4A drives Th2 responses by binding to receptor ILT-4. AB - Semaphorin-4A (Sema4A) has been implicated in the co-stimulation of T cells and drives Th1 immune responses by binding to the receptor T-cell immunoglobulin and mucin domain protein 2 (Tim-2) in mice. Here we show that human, but not murine, Sema4A is preferentially expressed on antigen-presenting cells, and co-stimulates CD4+ T-cell proliferation and drives Th2 responses. By employing two independent cloning strategies, we demonstrate that Immunoglobulin-like transcript 4 (ILT-4) is a receptor for human SEMA4A (hSEMA4A) on activated CD4+ T cells. We also find hSEMA4A to be highly expressed in human asthmatic lung tissue, implying its potential function in disease pathogenesis. Our study defines a different biological function of hSEMA4A from its murine homolog through its binding to the receptor of ILT-4 to co-stimulate CD4+T cells and regulate Th2 cells differentiation. PMID- 29467367 TI - Removal of artificial sweeteners and their effects on microbial communities in sequencing batch reactors. AB - Concern is growing over contamination of the environment with artificial sweeteners (ASWs) because of their widespread existence in wastewater treatment plants (WWTPs). To evaluate ASWs removal and the effect on activated sludge, acesulfame (ACE), sucralose (SUC), cyclamate (CYC) and saccharin (SAC) were introduced individually or in mixture to sequencing batch reactors (SBRs) in environmentally relevant concentrations (100 ppb) for 100 days. Comparisons between ACE removal in a full-scale WWTP and in lab-scale SBRs were conducted. Results showed that CYC and SAC were completely removed, whereas SUC was persistent. However, ACE removal in lab-scale SBRs was significantly greater than in the full-scale WWTP. In SBRs, chemical oxygen demand (COD), ammonia nitrogen (NH4+-N) and total nitrogen (TN) removal appeared unchanged after adding ASWs (p > 0.05). Adenosine triphosphate (ATP) concentrations and triphenyl tetrazolium chloride-dehydrogenase activity (TTC-DHA) declined significantly (p < 0.05). The mixed ASWs had more evident effects than the individual ASWs. Microbial community analyses revealed that Proteobacteria decreased obviously, while Bacteroidetes, Chloroflexi and Actinobacteria were enriched with the addition of ASWs. Redundancy Analysis (RDA) indicated ACE had a greater impact on activated sludge than the other ASWs. PMID- 29467368 TI - Culture-free bacterial detection and identification from blood with rapid, phenotypic, antibiotic susceptibility testing. AB - The current culture-based approach for the diagnosis of bloodstreams infection is incommensurate with timely treatment and curbing the prevalence of multi-drug resistant organisms (MDROs) due to its long time-to-result. Bloodstream infections typically involve extremely low (e.g., <10 colony-forming unit (CFU)/mL) bacterial concentrations that require a labor-intensive process and as much as 72 hours to yield a diagnosis. Here, we demonstrate a culture-free approach to achieve rapid diagnosis of bloodstream infections. An immuno detection platform with intrinsic signal current amplification was developed for the ultrasensitive, rapid detection, identification (ID) and antibiotic susceptibility testing (AST) of infections. With its capability of monitoring short-term (1-2 hours) bacterial growth in blood, the platform is able to provide 84-minute simultaneous detection and ID in blood samples below the 10 CFU/mL level and 204-minute AST. The susceptible-intermediate-resistant AST capacity was demonstrated. PMID- 29467370 TI - The impact of computed high b-value images on the diagnostic accuracy of DWI for prostate cancer: A receiver operating characteristics analysis. AB - To evaluate the performance of computed high b value diffusion-weighted images (DWI) in prostate cancer detection. 97 consecutive patients who had undergone multiparametric MRI of the prostate followed by biopsy were reviewed. Five radiologists independently scored 138 lesions on native high b-value images (b = 1200 s/mm2), apparent diffusion coefficient (ADC) maps, and computed high b-value images (contrast equivalent to b = 2000 s/mm2) to compare their diagnostic accuracy. Receiver operating characteristic (ROC) analysis and McNemar's test were performed to assess the relative performance of computed high b value DWI, native high b-value DWI and ADC maps. No significant difference existed in the area under the curve (AUC) for ROCs comparing B1200 (b = 1200 s/mm2) to computed B2000 (c-B2000) in 5 readers. In 4 of 5 readers c-B2000 had significantly increased sensitivity and/or decreased specificity compared to B1200 (McNemar's p < 0.05), at selected thresholds of interpretation. ADC maps were less accurate than B1200 or c-B2000 for 2 of 5 readers (P < 0.05). This study detected no consistent improvement in overall diagnostic accuracy using c-B2000, compared with B1200 images. Readers detected more cancer with c-B2000 images (increased sensitivity) but also more false positive findings (decreased specificity). PMID- 29467369 TI - Transcriptomic signature of drought response in pearl millet (Pennisetum glaucum (L.) and development of web-genomic resources. AB - Pearl millet, (Pennisetum glaucum L.), an efficient (C4) crop of arid/semi-arid regions is known for hardiness. Crop is valuable for bio-fortification combating malnutrition and diabetes, higher caloric value and wider climatic resilience. Limited studies are done in pot-based experiments for drought response at gene expression level, but field-based experiment mimicking drought by withdrawal of irrigation is still warranted. We report de novo assembly-based transcriptomic signature of drought response induced by irrigation withdrawal in pearl millet. We found 19983 differentially expressed genes, 7595 transcription factors, gene regulatory network having 45 hub genes controlling drought response. We report 34652 putative markers (4192 simple sequence repeats, 12111 SNPs and 6249 InDels). Study reveals role of purine and tryptophan metabolism in ABA accumulation mediating abiotic response in which MAPK acts as major intracellular signal sensing drought. Results were validated by qPCR of 13 randomly selected genes. We report the first web-based genomic resource ( http://webtom.cabgrid.res.in/pmdtdb/ ) which can be used for candidate genes based SNP discovery programs and trait-based association studies. Looking at climatic change, nutritional and pharmaceutical importance of this crop, present investigation has immense value in understanding drought response in field condition. This is important in germplasm management and improvement in endeavour of pearl millet productivity. PMID- 29467371 TI - Predatory flying squids are detritivores during their early planktonic life. AB - Cephalopods are primarily active predators throughout life. Flying squids (family Ommastrephidae) represents the most widely distributed and ecologically important family of cephalopods. While the diets of adult flying squids have been extensively studied, the first feeding diet of early paralarvae remains a mystery. The morphology of this ontogenetic stage notably differs from other cephalopod paralarvae, suggesting a different feeding strategy. Here, a combination of Laser Capture Microdissection (LCM) and DNA metabarcoding of wild collected paralarvae gut contents for eukaryotic 18S v9 and prokaryotic 16S rRNA was applied, covering almost every life domain. The gut contents were mainly composed by fungus, plants, algae and animals of marine and terrestrial origin, as well as eukaryotic and prokaryotic microorganisms commonly found in fecal pellets and particulate organic matter. This assemblage of gut contents is consistent with a diet based on detritus. The ontogenetic shift of diet from detritivore suspension feeding to active predation represents a unique life strategy among cephalopods and allows ommastrephid squids to take advantage of an almost ubiquitous and accessible food resource during their early stages. LCM was successfully applied for the first time to tiny, wild-collected marine organisms, proving its utility in combination with DNA metabarcoding for dietary studies. PMID- 29467372 TI - Chiral Ag23 nanocluster with open shell electronic structure and helical face centered cubic framework. AB - We report the synthesis and crystal structure of a nanocluster composed of 23 silver atoms capped by 8 phosphine and 18 phenylethanethiolate ligands. X-ray crystallographic analysis reveals that the kernel of the Ag nanocluster adopts a helical face-centered cubic structure with C2 symmetry. The thiolate ligands show two binding patterns with the surface Ag atoms: tri- and tetra-podal types. The tetra-coordination mode of thiolate has not been found in previous Ag nanoclusters. No counter ion (e.g., Na+ and NO3-) is found in the single-crystal and the absence of such ions is also confirmed by X-ray photoelectron spectroscopy analysis, indicating electrical neutrality of the nanocluster. Interestingly, the nanocluster has an open shell electronic structure (i.e., 23(Ag 5s1)-18(SR) = 5e), as confirmed by electron paramagnetic resonance spectroscopy. Time-dependent density functional theory calculations are performed to correlate the structure and optical absorption/emission spectra of the Ag nanocluster. PMID- 29467373 TI - Deep learning based tissue analysis predicts outcome in colorectal cancer. AB - Image-based machine learning and deep learning in particular has recently shown expert-level accuracy in medical image classification. In this study, we combine convolutional and recurrent architectures to train a deep network to predict colorectal cancer outcome based on images of tumour tissue samples. The novelty of our approach is that we directly predict patient outcome, without any intermediate tissue classification. We evaluate a set of digitized haematoxylin eosin-stained tumour tissue microarray (TMA) samples from 420 colorectal cancer patients with clinicopathological and outcome data available. The results show that deep learning-based outcome prediction with only small tissue areas as input outperforms (hazard ratio 2.3; CI 95% 1.79-3.03; AUC 0.69) visual histological assessment performed by human experts on both TMA spot (HR 1.67; CI 95% 1.28 2.19; AUC 0.58) and whole-slide level (HR 1.65; CI 95% 1.30-2.15; AUC 0.57) in the stratification into low- and high-risk patients. Our results suggest that state-of-the-art deep learning techniques can extract more prognostic information from the tissue morphology of colorectal cancer than an experienced human observer. PMID- 29467374 TI - Multi-terminal spin valve in a strong Rashba channel exhibiting three resistance states. AB - In a strong spin-orbit interaction system, the existence of three resistance states were observed when two ferromagnetic (FM) contacts were used as current terminals while a separate normal metal contact pair was used as voltage terminals. This result is strikingly different from ordinary spin valve or magnetic tunnel junction devices, which have only two resistance states corresponding to parallel (RP) and antiparallel (RAP) alignments of the FM contacts. Our experimental results on a quantum well layer with a strong Rashba effect clearly exhibit unequal antiparallel states, i.e., RAP(1) > RP > RAP(2), up to room temperature. The three-states are observed without any degradation when the distance between the non-magnetic voltage probe and the ferromagnetic current probe was increased up to 1.6 mm. PMID- 29467375 TI - Phosphorus addition changes belowground biomass and C:N:P stoichiometry of two desert steppe plants under simulated N deposition. AB - Many studies have reported that increasing atmospheric nitrogen (N) deposition broadens N:phosphorus (P) in both soils and plant leaves and potentially intensifies P limitation for plants. However, few studies have tested whether P addition alleviates N-induced P limitation for plant belowground growth. It is also less known how changed N:P in soils and leaves affect plant belowground stoichiometry, which is significant for maintaining key belowground ecological processes. We conducted a multi-level N:P supply experiment (varied P levels combined with constant N amount) for Glycyrrhiza uralensis (a N fixing species) and Pennisetum centrasiaticum (a grass) from a desert steppe in Northwest China during 2011-2013. Results showed that increasing P addition increased the belowground biomass and P concentrations of both species, resulting in the decreases in belowground carbon (C):P and N:P. These results indicate that P inputs alleviated N-induced P limitation and hence stimulated belowground growth. Belowground C:N:P stoichiometry of both species, especially P. centrasiaticum, tightly linked to soil and green leaf C:N:P stoichiometry. Thus, the decoupling of C:N:P ratios in both soils and leaves under a changing climate could directly alter plant belowground stoichiometry, which will in turn have important feedbacks to primary productivity and C sequestration. PMID- 29467376 TI - Changes in functional brain network topology after successful and unsuccessful corpus callosotomy for Lennox-Gastaut Syndrome. AB - Corpus callosotomy (CC) is an effective palliative surgical treatment for patients with Lennox-Gastaut Syndrome (LGS). However, research on the long-term functional effects of CC is sparse. We aimed to investigate these effects and their associated clinical conditions over the two years after CC. Long-term clinical EEG recordings of 30 patients with LGS who had good and bad seizure outcome after CC were collected and retrospectively studied. It was found that CC caused brain network 'hubs' to shift from paramedian to lateral regions in the good-recovery group, which reorganized the brain network into a more homogeneous state. We also found increased local clustering coefficients in patients with bad outcomes and decreases, implying enhanced network integration, in patients with good outcomes. The small worldness of brain networks in patients with good outcomes increased in the two years after CC, whereas it decreased in patients with bad outcomes. The covariation of small-worldness with the rate of reduction in seizure frequency suggests that this can be used as an indicator of CC outcome. Local and global network changes during the long-term state might be associated with the postoperative recovery process and could serve as indicators for CC outcome and long-term LGS recovery. PMID- 29467377 TI - Evolution of extrema features reveals optimal stimuli for biological state transitions. AB - The ability to define the unique features of an input stimulus needed to control switch-like behavior in biological systems is an important problem in computational biology and medicine. We show in this study how highly complex and intractable optimization problems can be simplified by restricting the search to the signal's extrema as key feature points, and evolving the extrema features towards optimal solutions that closely match solutions derived from gradient based methods. Our results suggest a model-independent approach for solving a class of optimization problems related to controlling switch-like state transitions. PMID- 29467378 TI - InForm software: a semi-automated research tool to identify presumptive human hepatic progenitor cells, and other histological features of pathological significance. AB - Hepatic progenitor cells (HPCs) play an important regenerative role in acute and chronic liver pathologies. Liver disease research often necessitates the grading of disease severity, and pathologists' reports are the current gold-standard for assessment. However, it is often impractical to recruit pathologists in large cohort studies. In this study we utilise PerkinElmer's "InForm" software package to semi-automate the scoring of patient liver biopsies, and compare outputs to a pathologist's assessment. We examined a cohort of eleven acute hepatitis samples and three non-alcoholic fatty liver disease (NAFLD) samples, stained with HPC markers (GCTM-5 and Pan Cytokeratin), an inflammatory marker (CD45), Sirius Red to detect collagen and haematoxylin/eosin for general histology. InForm was configured to identify presumptive HPCs, CD45+ve inflammatory cells, areas of necrosis, fat and collagen deposition (p < 0.0001). Hepatitis samples were then evaluated both by a pathologist using the Ishak-Knodell scoring system, and by InForm through customised algorithms. Necroinflammation as evaluated by a pathologist, correlated with InForm outputs (r2 = 0.8192, p < 0.05). This study demonstrates that the InForm software package provides a useful tool for liver disease research, allowing rapid, and objective quantification of the presumptive HPCs and identifies histological features that assist with assessing liver disease severity, and potentially can facilitate diagnosis.

PMID- 29467380 TI - Planctopirus hydrillae sp. nov., an antibiotic producing Planctomycete isolated from the aquatic plant Hydrilla and its whole genome shotgun sequence analysis. AB - An antibiotic producing novel Planctomycete strain, designated JC280T, was isolated from the surface of the plant Hydrilla verticillata collected from an alkaline lake (Buffalo lake), University of Hyderabad, Hyderabad, India. The morphological and chemotaxonomic properties of strain JC280T were in agreement with the characteristics of the genus Planctopirus. The cell shape was spherical to ovoid and some were tear drop shaped. The cells were Gram-stain-negative divided by budding presenting stalks and rosette formation and were non sporulating. Crateriform structures with a sub-polar flagellum were observed. Characteristic polyamines were putrescine and spermidine. Diagnostic polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, an unidentified phospholipid (PL1), unidentified glycolipids (GL1-2), an unidentified aminophospholipid (APL), and an unidentified lipid (L3). Major (>10%) fatty acids were C16:0, C17:1omega8c, C18:1omega9c, and summed feature-3. Major (88%) respiratory quinone was MK-6 with minor amount (12%) of MK-7. Strain JC280T showed 99.7% 16S rRNA gene sequence similarity with Planctopirus limnophila DSM 3776T. To resolve their full taxonomic position, the genome sequence was obtained and compared with the available P. limnophila DSM 3776T genome. The genome sequence of strain JC280T was 5,750,243 bp in size with a total of 4490 protein-coding genes, 66 RNA genes, and 2 CRISPR repeats. Based on whole-genome statistics, ANI value, in silico DDH, diversity of secondary metabolite biosynthetic gene clusters, distinct physiological, biochemical and chemotaxonomic differences, strain JC280T represents a new species in the genus Planctopirus, for which the name Planctopirus hydrillae sp. nov. is proposed. The type strain is JC280T (=KCTC 42880T = LMG 29153T). PMID- 29467381 TI - TMCO1 is essential for ovarian follicle development by regulating ER Ca2+ store of granulosa cells. AB - TMCO1 (transmembrane and coiled-coil domains 1) is an endoplasmic reticulum (ER) transmembrane protein that actively prevents Ca2+ stores from overfilling. To characterize its physiological function(s), we generated Tmco1-/- knockout (KO) mice. In addition to the main clinical features of human cerebrofaciothoracic (CFT) dysplasia spectrum, Tmco1-/- females manifest gradual loss of ovarian follicles, impaired ovarian follicle development, and subfertility with a phenotype analogous to the premature ovarian failure (POF) in women. In line with the role of TMCO1 as a Ca2+ load-activated Ca2+ channel, we have detected a supernormal Ca2+ signaling in Tmco1-/- granulosa cells (GCs). Interestingly, although spontaneous Ca2+ oscillation pattern was altered, ER Ca2+ stores of germinal vesicle (GV) stage oocytes and metaphase II (MII) arrested eggs were normal upon Tmco1 ablation. Combined with RNA-sequencing analysis, we also detected increased ER stress-mediated apoptosis and enhanced reactive oxygen species (ROS) level in Tmco1-/- GCs, indicating the dysfunctions of GCs upon TMCO1 deficiency. Taken together, these results reveal that TMCO1 is essential for ovarian follicle development and female fertility by maintaining ER Ca2+ homeostasis of GCs, disruption of which causes ER stress-mediated apoptosis and increased cellular ROS level in GCs and thus leads to impaired ovarian follicle development. PMID- 29467382 TI - KRAB-type zinc-finger proteins PITA and PISA specifically regulate p53-dependent glycolysis and mitochondrial respiration. AB - Few p53 regulators participate in selective control of p53-mediated cellular metabolism. How p53-mediated aerobic and glycolytic pathways are negatively regulated remains largely unclear. Here, we identified two KRAB-type zinc-finger proteins, PITA (p53 inhibitor of TIGAR activation) and PISA (p53 inhibitor of SCO2 activation), as selective regulators of p53 in metabolic control. PITA and PISA interact with p53 and specifically suppress transcription of the glycolysis regulator TIGAR and the oxidation phosphorylation regulator SCO2, respectively. Importantly, PITA transgenic mice exhibited increased 6-phosphofructokinase 1 (PFK1) activity and an elevated glycolytic rate, whereas PISA transgenic mice had decreased cytochrome c oxidase activity and reduced mitochondrial respiration. In response to glucose starvation, PITA dissociates from p53, resulting in activation of p53 and induction of TIGAR, which inhibited aerobic glycolysis. Prolonged starvation leads to PISA dissociation from p53 and induction of SCO2 and p53-promoted mitochondrial respiration. The dynamic regulation of PITA and PISA upon metabolic stress is dependent on ATM kinase-mediated phosphorylation of PITA and PISA. Furthermore, in human colorectal cancers, the elevated expression of PITA and PISA correlates with cancer progression. Depletion of PITA or PISA in colorectal cancer cells reduced the cell proliferation, migration and invasion. These results identify PITA and PISA as selective regulators of p53-mediated glycolysis and mitochondrial respiration and provide novel insights into the role of p53 network in cell metabolic control.

PMID- 29467385 TI - The novel dithiocarbamate, DpdtC suppresses HER2-overexpressed cancer cells by up regulating NDRG1 via inactivation of HER2-ERK 1/2 signaling. AB - Dithiocarbamate has been tested for its effective anti-tumor activity, but the underlying mechanism remains unclear. We previously prepared a novel diththiocarbamate derivative, DpdtC with an ability of catalase inhibition. Here, we for the first time investigated the growth inhibition effects of DpdtC on HER2 amplified cancer cells and elucidated its mechanism of action. Results showed that DpdtC exerted the potent anti-tumor effects against HER2-overexpressed SK-OV 3 and SK-BR-3 cells, especially on SK-OV-3 cells with a higher NDRG1 level, which was also confirmed in the SK-OV-3 xenograft model. Interestingly, we observed that NDRG1 was up-regulated, while membrane expression of HER2 was regressed in SK-OV-3 cells upon DpdtC treatment. In agreement, silencing endogenous NDRG1 also increased the expression of HER2 in SK-OV-3 cells, while overexpressing NDRG1 decreased HER2 expression in SK-BR-3 cells. Furthermore, our results showed the formation of the EGFR/HER2 heterodimer was attenuated and phosphorylation of ERK1/2 was inhibited in SK-OV-3 cells when treated with DpdtC. Collectively, these observations demonstrated that NDRG1 plays an important role in mediating the inhibition effects of DpdtC in HER2-overexpressed cancer cells via selective targeting of the HER2-ERK1/2 pathway. Hence, our investigation suggests that up regulation of NDRG1 by DpdtC is a promising therapeutic approach in HER2 overexpressed cancers. PMID- 29467386 TI - BMI reduction and vitamin D insufficiency mediated osteoporosis and fragility fractures in patients at nutritional risk: a cross-sectional study. AB - It seemed to be common sense that malnutrition was associated with osteoporosis, but there were few studies with detailed data proving that. Additionally, the association between BMI and osteoporosis was still under discussion. In our study of 138 patients, we first confirmed the association between nutrition and osteoporosis with propensity score matching method reducing the confounding bias, then discovered that body mass index (BMI) and 25OHD level acted as two crucial factors of nutrition risk-mediated osteoporosis. Moreover, a new BMI classification was proposed in our article to do more help for nutrition management and anti-osteoporosis treatment for the old in China. Consequently, nutrition is important to bone health, with BMI and 25OHD level playing key roles. PMID- 29467387 TI - Clinical Utility Gene Card for: Becker muscular dystrophy. PMID- 29467388 TI - A novel MAP3K7 splice mutation causes cardiospondylocarpofacial syndrome with features of hereditary connective tissue disorder. AB - Heterozygous variants in MAP3K7, encoding the transforming growth factor-beta activated kinase 1 (TAK1), are associated with the ultrarare cardiospondylocarpofacial syndrome (CSCFS). Specific gain-of-function variants in the same gene cause the allelic frontometaphyseal dysplasia type 2. Phenotypic series of frontometaphyseal dysplasia also comprise variants in FLNA (type 1) and two patients with a heterozygous variant in TAB2 (type 3). We report on a 7-year old girl with CSCFS due to the novel heterozygous c.737-7A>G variant in MAP3K7. The identified variant generates a new splice acceptor site causing an in-frame insertion of 2 amino acid residues (p.Asn245_Gly246insValVal), as demonstrated by RNA study. The patient was originally ascertained for a presumed hereditary connective tissue disorder due to soft/dystrophic skin, extreme joint hypermobility, polyvalvular heart disease, and upper gastrointestinal dismotility. Our study confirms locus homogeneity for CSCFS, expands the mutational spectrum of MAP3K7, and adds data on the existence of a community of connective tissue disorders caused by abnormalities of the TAK1-dependent signaling pathway. PMID- 29467389 TI - Long glucocorticoid-induced leucine zipper regulates human thyroid cancer cell proliferation. AB - Long glucocorticoid-induced leucine zipper (L-GILZ) has recently been implicated in cancer cell proliferation. Here, we investigated its role in human thyroid cancer cells. L-GILZ protein was highly expressed in well-differentiated cancer cells from thyroid cancer patients and differentiated thyroid cancer cell lines, but poorly expressed in anaplastic tumors. A fusion protein containing L-GILZ, when overexpressed in an L-GILZ-deficient 8505C cell line derived from undifferentiated human thyroid cancer tissue, inhibited cellular proliferation in vitro. In addition, when this protein was injected into nude mice, in which cells from line 8505C had been transplanted, xenograft growth was reduced. Since the mitogen-activated protein kinase (MAPK) pathway is frequently hyperactivated in thyroid cancer cells as a result of the BRAFV600E or Ras mutation, we sought to further investigate the role of L-GILZ in the MAPK pathway. To this end, we analyzed L-GILZ expression and function in cells treated with MAPK inhibitors. We used 8505C cells, which have the BRAFV600E mutation, or the CAL-62 cell line, which harbors a Ras mutation. The cells were treated with the BRAF-specific drug vemurafenib (PLX4032) or the MEK1/2 inhibitor, U0126, respectively. Treatment with these agents inhibited MAPK activation, reduced cell proliferation, and upregulated L-GILZ expression. L-GILZ silencing reversed the antiproliferative activity of the MAPK inhibitors, consistent with an antiproliferative role. Treatment with MAPK inhibitors led to the phosphorylation of the cAMP/response element-binding protein (CREB), and active CREB bound to the L-GILZ promoter, contributing to its transcription. We suggest that the CREB signaling pathway, frequently deregulated in thyroid tumors, is involved in L-GILZ upregulation and that L-GILZ regulates thyroid cancer cell proliferation, which may have potential in cancer treatment. PMID- 29467390 TI - FGF1 induces resistance to chemotherapy in ovarian granulosa tumor cells through regulation of p53 mitochondrial localization. AB - Ovarian cancer remains associated with a high mortality rate and relapse is too frequently seen after chemotherapeutic treatment of granulosa cell tumors (GCTs) or epithelial ovarian cancers (EOCs). It is thus of major importance to progress in the knowledge of the molecular mechanisms underlying chemoresistance of ovarian tumors. Overexpression of Fibroblast Growth Factor 1 (FGF1) is observed in various cancers, correlates with poor survival and could be responsible for resistance to platinum-based chemotherapy of serous ovarian cancers. How FGF1 promotes escape to chemotherapy remains unknown. In previous studies, we showed that FGF1 inhibits p53 transcriptional activities, leading to increased cell survival of neuronal or fibroblast cell lines. In this study, we show that FGF1 favors survival of COV434 cells upon treatment with etoposide and cisplatin, two common chemotherapeutic molecules used for ovarian cancer. Etoposide and cisplatin induced mitochondrial depolarization, cytochrome c release and caspase activation in COV434 cells. Overexpression of FGF1 counteracts these events and thus allows increased survival of ovarian cells. In this study, FGF1 had little effect on p53 stability and transcriptional activities. Etoposide induced p21 expression as expected, but p21 protein levels were even increased in the presence of FGF1. Using RNA interference, we showed that p21 exerts an anti apoptotic activity in COV434 cells. However abrogating this activity was not sufficient to restore cell death of FGF1-overexpressing cells. We also show for the first time that p53 mitochondrial pathway is involved in the cell death of COV434 cells. Indeed, p53 accumulates at mitochondria upon etoposide treatment and inhibition of p53 mitochondrial localization using pifithrin-u inhibits apoptosis of COV434 cells. FGF1 also decreases mitochondrial accumulation of p53 induced by etoposide. This constitutes a novel mechanism of action for FGF1 to promote cell survival in response to chemotherapy. PMID- 29467391 TI - Bio-inspired counter-current multiplier for enrichment of solutes. AB - Improving the efficiency of gas separation technology is a challenge facing modern industry, since existing methods for gas separation, including hollow fiber membrane contactors, vacuum swing adsorption, and cryogenic distillation, represents a significant portion of the world's energy consumption. Here, we report an enhancement in the release rate of carbon dioxide and oxygen of a thermal swing gas desorption unit using a counter-current amplification method inspired by fish. Differing from a conventional counter-current extraction system, counter-current amplification makes use of parallel capture fluid channels separated by a semipermeable membrane in addition to the semipermeable membrane separating the capture fluid channel and the gas release channel. The membrane separating the incoming and outgoing fluid channels allows gas that would normally exit the system to remain in the desorption unit. We demonstrate the system using both resistive heating and photothermal heating. With resistive heating, an increase in release rate of 240% was observed compared to an equivalent counter-current extraction system. PMID- 29467392 TI - Alcohol Impairs N100 Response to Dorsolateral Prefrontal Cortex Stimulation. AB - Alcohol is thought to exert its effect by acting on gamma-aminobutyric (GABA) inhibitory neurotransmission. The N100, the negative peak on electroencephalography (EEG) that occurs approximately 100 ms following the transcranial magnetic stimulation (TMS) pulse, is believed to represent GABAB receptor mediated neurotransmission. However, no studies have examined the effect of alcohol on the N100 response to TMS stimulation of the dorsolateral prefrontal cortex (DLPFC). In the present study, we aimed to explore the effect of alcohol on the DLPFC TMS-evoked N100 response. The study was a within-subject cross-over design study. Fifteen healthy alcohol drinkers were administered TMS to the DLPFC before (PreBev) and after consumption (PostBev) of an alcohol or placebo beverage. The amplitude of the N100 before and after beverage was compared for both the alcohol and placebo beverage. Alcohol produced a significant decrease in N100 amplitude (t = 4.316, df = 14, p = 0.001). The placebo beverage had no effect on the N100 amplitude (t = -1.856, df = 14, p = 0.085). Acute alcohol consumption produces a decrease in N100 amplitude to TMS stimulation of the DLPFC, suggesting a decrease in GABAB receptor mediated neurotransmission. Findings suggest that the N100 may represent a marker of alcohol's effects on inhibitory neurotransmission. PMID- 29467393 TI - A low cost and high performance polymer donor material for polymer solar cells. AB - The application of polymer solar cells requires the realization of high efficiency, high stability, and low cost devices. Here we demonstrate a low-cost polymer donor poly[(thiophene)-alt-(6,7-difluoro-2-(2-hexyldecyloxy)quinoxaline)] (PTQ10), which is synthesized with high overall yield of 87.4% via only two-step reactions from cheap raw materials. More importantly, an impressive efficiency of 12.70% is obtained for the devices with PTQ10 as donor, and the efficiency of the inverted structured PTQ10-based device also reaches 12.13% (certificated to be 12.0%). Furthermore, the as-cast devices also demonstrate a high efficiency of 10.41% and the devices exhibit insensitivity of active layer thickness from 100 nm to 300 nm, which is conductive to the large area fabrication of the devices. In considering the advantages of low cost and high efficiency with thickness insensitivity, we believe that PTQ10 will be a promising polymer donor for commercial application of polymer solar cells. PMID- 29467394 TI - Development of a high-throughput assay for rapid screening of butanologenic strains. AB - We report a Thermotoga hypogea (Th) alcohol dehydrogenase (ADH)-dependent spectrophotometric assay for quantifying the amount of butanol in growth media, an advance that will facilitate rapid high-throughput screening of hypo- and hyper-butanol-producing strains of solventogenic Clostridium species. While a colorimetric nitroblue tetrazolium chloride-based assay for quantitating butanol in acetone-butanol-ethanol (ABE) fermentation broth has been described previously, we determined that Saccharomyces cerevisiae (Sc) ADH used in this earlier study exhibits approximately 13-fold lower catalytic efficiency towards butanol than ethanol. Any Sc ADH-dependent assay for primary quantitation of butanol in an ethanol-butanol mixture is therefore subject to "ethanol interference". To circumvent this limitation and better facilitate identification of hyper-butanol-producing Clostridia, we searched the literature for native ADHs that preferentially utilize butanol over ethanol and identified Th ADH as a candidate. Indeed, recombinant Th ADH exhibited a 6-fold higher catalytic efficiency with butanol than ethanol, as measured using the reduction of NADP+ to NADPH that accompanies alcohol oxidation. Moreover, the assay sensitivity was not affected by the presence of acetone, acetic acid or butyric acid (typical ABE fermentation products). We broadened the utility of our assay by adapting it to a high-throughput microtiter plate-based format, and piloted it successfully in an ongoing metabolic engineering initiative. PMID- 29467395 TI - Spatial geometry of stem cell proliferation in the adult hippocampus. AB - The modes of stem cell divisions (e.g., symmetric vs. asymmetric) can have a profound impact on the number of progeny and tissue growth, repair, and function. This is particularly relevant for adult neural stem cells, since stem cell derived neurons affect cognitive and mental states, resistance to stress and disease, and response to therapies. Here we show that although dividing stem cells in the adult hippocampus display a certain bias towards paired distribution (which could imply the prevalence of symmetric divisions), this bias already exists in the distribution of the general population of stem cells and may be responsible for the perceived occurrence of symmetric stem cell divisions. Remarkably, the bias in the distribution of stem cells decreases with age. Our results argue that the preexisting bias in stem cell distribution may affect current assumptions regarding stem cell division and fate as well as conjectures on the prospects of brain repair and rejuvenation. PMID- 29467396 TI - Trace metals from historical mining sites and past metallurgical activity remain bioavailable to wildlife today. AB - Throughout history, ancient human societies exploited mineral resources all over the world, even in areas that are now protected and considered to be relatively pristine. Here, we show that past mining still has an impact on wildlife in some French protected areas. We measured cadmium, copper, lead, and zinc concentrations in topsoils and wood mouse kidneys from sites located in the Cevennes and the Morvan. The maximum levels of metals in these topsoils are one or two orders of magnitude greater than their commonly reported mean values in European topsoils. The transfer to biota was effective, as the lead concentration (and to a lesser extent, cadmium) in wood mouse kidneys increased with soil concentration, unlike copper and zinc, providing direct evidence that lead emitted in the environment several centuries ago is still bioavailable to free ranging mammals. The negative correlation between kidney lead concentration and animal body condition suggests that historical mining activity may continue to play a role in the complex relationships between trace metal pollution and body indices. Ancient mining sites could therefore be used to assess the long-term fate of trace metals in soils and the subsequent risks to human health and the environment. PMID- 29467397 TI - Expanded diversity of microbial groups that shape the dissimilatory sulfur cycle. AB - A critical step in the biogeochemical cycle of sulfur on Earth is microbial sulfate reduction, yet organisms from relatively few lineages have been implicated in this process. Previous studies using functional marker genes have detected abundant, novel dissimilatory sulfite reductases (DsrAB) that could confer the capacity for microbial sulfite/sulfate reduction but were not affiliated with known organisms. Thus, the identity of a significant fraction of sulfate/sulfite-reducing microbes has remained elusive. Here we report the discovery of the capacity for sulfate/sulfite reduction in the genomes of organisms from 13 bacterial and archaeal phyla, thereby more than doubling the number of microbial phyla associated with this process. Eight of the 13 newly identified groups are candidate phyla that lack isolated representatives, a finding only possible given genomes from metagenomes. Organisms from Verrucomicrobia and two candidate phyla, Candidatus Rokubacteria and Candidatus Hydrothermarchaeota, contain some of the earliest evolved dsrAB genes. The capacity for sulfite reduction has been laterally transferred in multiple events within some phyla, and a key gene potentially capable of modulating sulfur metabolism in associated cells has been acquired by putatively symbiotic bacteria. We conclude that current functional predictions based on phylogeny significantly underestimate the extent of sulfate/sulfite reduction across Earth's ecosystems. Understanding the prevalence of this capacity is integral to interpreting the carbon cycle because sulfate reduction is often coupled to turnover of buried organic carbon. Our findings expand the diversity of microbial groups associated with sulfur transformations in the environment and motivate revision of biogeochemical process models based on microbial community composition. PMID- 29467398 TI - A virus or more in (nearly) every cell: ubiquitous networks of virus-host interactions in extreme environments. AB - The application of viral and cellular metagenomics to natural environments has expanded our understanding of the structure, functioning, and diversity of microbial and viral communities. The high diversity of many communities, e.g., soils, surface ocean waters, and animal-associated microbiomes, make it difficult to establish virus-host associations at the single cell (rather than population) level, assign cellular hosts, or determine the extent of viral host range from metagenomics studies alone. Here, we combine single-cell sequencing with environmental metagenomics to characterize the structure of virus-host associations in a Yellowstone National Park (YNP) hot spring microbial community. Leveraging the relatively low diversity of the YNP environment, we are able to overlay evidence at the single-cell level with contextualized viral and cellular community structure. Combining evidence from hexanucelotide analysis, single cell read mapping, network-based analytics, and CRISPR-based inference, we conservatively estimate that >60% of cells contain at least one virus type and a majority of these cells contain two or more virus types. Of the detected virus types, nearly 50% were found in more than 2 cellular clades, indicative of a broad host range. The new lens provided by the combination of metaviromics and single-cell genomics reveals a network of virus-host interactions in extreme environments, provides evidence that extensive virus-host associations are common, and further expands the unseen impact of viruses on cellular life. PMID- 29467399 TI - Assessment of novel vaccination regimens using viral vectored liver stage malaria vaccines encoding ME-TRAP. AB - Heterologous prime-boost vaccination with viral vectors simian adenovirus 63 (ChAd63) and Modified Vaccinia Ankara (MVA) induces potent T cell and antibody responses in humans. The 8-week regimen demonstrates significant efficacy against malaria when expressing the pre-erythrocytic malaria antigen Thrombospondin Related Adhesion Protein fused to a multiple epitope string (ME-TRAP). We tested these vaccines in 7 new 4- and 8- week interval schedules to evaluate safety and immunogenicity of multiple ChAd63 ME-TRAP priming vaccinations (denoted A), multiple MVA ME-TRAP boosts (denoted M) and alternating vectors. All regimens exhibited acceptable reactogenicity and CD8+ T cell immunogenicity was enhanced with a 4-week interval (AM) and with incorporation of additional ChAd63 ME-TRAP vaccination at 4- or 8-weeks (AAM or A_A_M). Induction of TRAP antibodies was comparable between schedules. T cell immunity against the ChAd63 hexon did not affect T cell responses to the vaccine insert, however pre-vaccination ChAd63 specific T cells correlated with reduced TRAP antibodies. Vaccine-induced antibodies against MVA did not affect TRAP antibody induction, and correlated positively with ME-TRAP-specific T cells. This study identifies potentially more effective immunisation regimens to assess in Phase IIa trials and demonstrates a degree of flexibility with the timing of vectored vaccine administration, aiding incorporation into existing vaccination programmes. PMID- 29467400 TI - A Saliva Protein of Varroa Mites Contributes to the Toxicity toward Apis cerana and the DWV Elevation in A. mellifera. AB - Varroa destructor mites express strong avoidance of the Apis cerana worker brood in the field. The molecular mechanism for this phenomenon remains unknown. We identified a Varroa toxic protein (VTP), which exhibited toxic activity toward A. cerana worker larvae, in the saliva of these mites, and expressed VTP in an Escherichia coli system. We further demonstrated that recombinant VTP killed A. cerana worker larvae and pupae in the absence of deformed-wing virus (DWV) but was not toxic to A. cerana worker adults and drones. The recombinant VTP was safe for A. mellifera individuals, but resulted in elevated DWV titers and the subsequent development of deformed-wing adults. RNAi-mediated suppression of vtp gene expression in the mites partially protected A. cerana larvae. We propose a modified mechanism for Varroa mite avoidance of worker brood, due to mutual destruction stress, including the worker larvae blocking Varroa mite reproduction and Varroa mites killing worker larvae by the saliva toxin. The discovery of VTP should provide a better understanding of Varroa pathogenesis, facilitate host parasite mechanism research and allow the development of effective methods to control these harmful mites. PMID- 29467401 TI - dynGENIE3: dynamical GENIE3 for the inference of gene networks from time series expression data. AB - The elucidation of gene regulatory networks is one of the major challenges of systems biology. Measurements about genes that are exploited by network inference methods are typically available either in the form of steady-state expression vectors or time series expression data. In our previous work, we proposed the GENIE3 method that exploits variable importance scores derived from Random forests to identify the regulators of each target gene. This method provided state-of-the-art performance on several benchmark datasets, but it could however not specifically be applied to time series expression data. We propose here an adaptation of the GENIE3 method, called dynamical GENIE3 (dynGENIE3), for handling both time series and steady-state expression data. The proposed method is evaluated extensively on the artificial DREAM4 benchmarks and on three real time series expression datasets. Although dynGENIE3 does not systematically yield the best performance on each and every network, it is competitive with diverse methods from the literature, while preserving the main advantages of GENIE3 in terms of scalability. PMID- 29467402 TI - Development of a model predicting non-satisfaction 1 year after primary total knee replacement in the UK and transportation to Switzerland. AB - We aimed to develop a predictive model for non-satisfaction following primary total knee replacement (TKR) and to assess its transportability to another health care system. Data for model development were obtained from two UK tertiary hospitals. Model transportation data were collected from Geneva University Hospitals in Switzerland. Participants were individuals undergoing primary TKR with non-satisfaction with surgery after one year the outcome of interest. Multiple imputation and logistic regression modelling with bootstrap backward selection were used to identify predictors of outcome. Model performance was assessed by discrimination and calibration. 64 (14.2%) patients in the UK and 157 (19.9%) in Geneva were non-satisfied with their TKR. Predictors in the UK cohort were worse pre-operative pain and function, current smoking, treatment for anxiety and not having been treated with injected corticosteroids (corrected AUC = 0.65). Transportation to the Geneva cohort showed an AUC of 0.55. Importantly, two UK predictors (treated for anxiety, injected corticosteroids) were not predictive in Geneva. A better model fit was obtained when coefficients were re estimated in the Geneva sample (AUC = 0.64). The model did not perform well when transported to a different country, but improved when it was re-estimated. This emphasises the need to re-validate the model for each setting/country. PMID- 29467403 TI - Proteome analysis of Aspergillus flavus isolate-specific responses to oxidative stress in relationship to aflatoxin production capability. AB - Aspergillus flavus is an opportunistic pathogen of plants such as maize and peanut under conducive conditions such as drought stress resulting in significant aflatoxin production. Drought-associated oxidative stress also exacerbates aflatoxin production by A. flavus. The objectives of this study were to use proteomics to provide insights into the pathogen responses to H2O2-derived oxidative stress, and to identify potential biomarkers and targets for host resistance breeding. Three isolates, AF13, NRRL3357, and K54A with high, moderate, and no aflatoxin production, were cultured in medium supplemented with varying levels of H2O2, and examined using an iTRAQ (Isobaric Tags for Relative and Absolute Quantification) approach. Overall, 1,173 proteins were identified and 220 were differentially expressed (DEPs). Observed DEPs encompassed metabolic pathways including antioxidants, carbohydrates, pathogenicity, and secondary metabolism. Increased lytic enzyme, secondary metabolite, and developmental pathway expression in AF13 was correlated with oxidative stress tolerance, likely assisting in plant infection and microbial competition. Elevated expression of energy and cellular component production in NRRL3357 and K54A implies a focus on oxidative damage remediation. These trends explain isolate-to-isolate variation in oxidative stress tolerance and provide insights into mechanisms relevant to host plant interactions under drought stress allowing for more targeted efforts in host resistance research. PMID- 29467405 TI - MUC13 contributes to rewiring of glucose metabolism in pancreatic cancer. AB - Pancreatic tumors are rewired for high-glucose metabolism and typically present with exceptionally poor prognosis. Recently, we have shown that MUC13, which is highly expressed in pancreatic tumors, promotes tumor progression via modulation of HER2 receptor tyrosine kinase activity. Herein, we investigate a novel, MUC13 mediated molecular mechanism responsible for higher glucose metabolism in pancreatic tumors. Our results demonstrate that MUC13 expression leads to the activation/nuclear translocation of NF-kappaB p65 and phosphorylation of IkappaB, which in turn upregulates the expression of important proteins (Glut-1, c-Myc, and Bcl-2) that are involved in glucose metabolism. MUC13 functionally interacts and stabilizes Glut-1 to instigate downstream events responsible for higher glucose uptake in pancreatic cancer cells. Altered MUC13 expression by overexpression and knockdown techniques effectively modulated glucose uptake, lactate secretion, and metastatic phenotypes in pancreatic cancer cells. NF kappaB inhibitor, Sulfasalazine, abrogates the MUC13 and Glut-1 interaction, and attenuates events associated with MUC13-induced glucose metabolism. Pancreatic ductal adenocarcinoma (PDAC) patient tissue samples also show a positive correlation between the expression of these two proteins. These results delineate how MUC13 rewire aberrant glucose metabolism to enhance aggressiveness of pancreatic cancer and revealed a novel mechanism to develop newer therapeutic strategies for this exceptionally difficult cancer. PMID- 29467404 TI - Basal condensation of Numb and Pon complex via phase transition during Drosophila neuroblast asymmetric division. AB - Uneven distribution and local concentration of protein complexes on distinct membrane cortices is a fundamental property in numerous biological processes, including Drosophila neuroblast (NB) asymmetric cell divisions and cell polarity in general. In NBs, the cell fate determinant Numb forms a basal crescent together with Pon and is segregated into the basal daughter cell to initiate its differentiation. Here we discover that Numb PTB domain, using two distinct binding surfaces, recognizes repeating motifs within Pon in a previously unrecognized mode. The multivalent Numb-Pon interaction leads to high binding specificity and liquid-liquid phase separation of the complex. Perturbations of the Numb/Pon complex phase transition impair the basal localization of Numb and its subsequent suppression of Notch signaling during NB asymmetric divisions. Such phase-transition-mediated protein condensations on distinct membrane cortices may be a general mechanism for various cell polarity regulatory complexes. PMID- 29467406 TI - Genetic variations in ARE1 mediate grain yield by modulating nitrogen utilization in rice. AB - In crops, nitrogen directly determines productivity and biomass. However, the improvement of nitrogen utilization efficiency (NUE) is still a major challenge in modern agriculture. Here, we report the characterization of are1, a genetic suppressor of a rice fd-gogat mutant defective in nitrogen assimilation. ARE1 is a highly conserved gene, encoding a chloroplast-localized protein. Loss-of function mutations in ARE1 cause delayed senescence and result in 10-20% grain yield increases, hence enhance NUE under nitrogen-limiting conditions. Analysis of a panel of 2155 rice varieties reveals that 18% indica and 48% aus accessions carry small insertions in the ARE1 promoter, which result in a reduction in ARE1 expression and an increase in grain yield under nitrogen-limiting conditions. We propose that ARE1 is a key mediator of NUE and represents a promising target for breeding high-yield cultivars under nitrogen-limiting condition. PMID- 29467407 TI - Maternal obesity-induced decreases in plasma, hepatic and uterine polyunsaturated fatty acids during labour is reversed through improved nutrition at conception. AB - Maternal obesity is associated with prolonged and dysfunctional labour, potentially through decreased synthesis of prostaglandins that stimulate myometrial contractions. We assessed the impact of maternal obesity on concentrations of precursor fatty acids (FA) for prostaglandin synthesis and whether any changes could be reversed by improved nutrition post-conception. Wistar rats were fed control (CON) or High-Fat, High-cholesterol (HFHC) diets 6 weeks before mating. At conception half the dams switched diets providing 4 dietary groups: (1) CON, (2) HFHC, (3) CON-HFHC or (4) HFHC-CON. During parturition rats were euthanized and FA composition of plasma, liver and uterus determined. Visceral fat was doubled in rats exposed to the HFHC diet prior to and/or during pregnancy compared to CON. HFHC diet increased MUFAs but decreased omega-3 and omega-6 PUFAs in plasma and liver. Uterine omega-3 FA concentrations were halved in HFHC versus CON rats, but all other FAs were similar. Switching from HFHC to CON diet at conception restored all FA profiles to those seen in CON rats. The increased MUFA and decreased PUFA concentrations in obese HFHC dams may contribute to aberrant prostaglandin synthesis and dysfunctional myometrial activity and it may be possible to reverse these changes, and potentially improve labour outcomes, by improving nutrition at conception. PMID- 29467409 TI - Combined use of CEMIP and CA 19-9 enhances diagnostic accuracy for pancreatic cancer. AB - Carbohydrate antigen (CA) 19-9 is the only diagnostic marker used in pancreatic cancer despite its limitations. Here, we aimed to identify the diagnostic role of CEMIP (also called KIAA1199) combined with CA 19-9 in patients with pancreatic cancer. A retrospective analysis of prospectively collected patient samples was performed to determine the benefit of diagnostic markers in the diagnosis of pancreatic cancer. We investigated CEMIP and CA 19-9 levels in 324 patients with pancreatic cancer and 49 normal controls using serum enzyme-linked immunosorbent assay. Median CA 19-9 and CEMIP levels were 410.5 U/ml (40.8-3342.5) and 0.67 ng/ml (0.40-1.08), respectively, in patients with pancreatic cancer. The AUROC for CA 19-9 and CEMIP were 0.847 (95% confidence interval [CI]: 0.806-0.888) and 0.760 (95% CI: 0.689-0.831), respectively. Combination of CA 19-9 with CEMIP showed markedly improved AUROC over CA 19-9 alone in pancreatic cancer diagnosis (0.94 vs. 0.89; P < 0.0001). CEMIP showed a diagnostic yield of 86.1% (68/79) in CA 19-9 negative pancreatic cancer. Combined use with CEMIP showed significantly improved diagnostic value compared with CA 19-9 alone in pancreatic cancer. Especially, CEMIP may be a complementary marker in pancreatic cancer patients with normal CA 19-9 levels. PMID- 29467408 TI - Prediction complements explanation in understanding the developing brain. AB - A central aim of human neuroscience is understanding the neurobiology of cognition and behavior. Although we have made significant progress towards this goal, reliance on group-level studies of the developed adult brain has limited our ability to explain population variability and developmental changes in neural circuitry and behavior. In this review, we suggest that predictive modeling, a method for predicting individual differences in behavior from brain features, can complement descriptive approaches and provide new ways to account for this variability. Highlighting the outsized scientific and clinical benefits of prediction in developmental populations including adolescence, we show that predictive brain-based models are already providing new insights on adolescent specific risk-related behaviors. Together with large-scale developmental neuroimaging datasets and complementary analytic approaches, predictive modeling affords us the opportunity and obligation to identify novel treatment targets and individually tailor the course of interventions for developmental psychopathologies that impact so many young people today. PMID- 29467410 TI - Analysis of cardiomyocyte clonal expansion during mouse heart development and injury. AB - The cellular mechanisms driving cardiac tissue formation remain poorly understood, largely due to the structural and functional complexity of the heart. It is unclear whether newly generated myocytes originate from cardiac stem/progenitor cells or from pre-existing cardiomyocytes that re-enter the cell cycle. Here, we identify the source of new cardiomyocytes during mouse development and after injury. Our findings suggest that cardiac progenitors maintain proliferative potential and are the main source of cardiomyocytes during development; however, the onset of alphaMHC expression leads to reduced cycling capacity. Single-cell RNA sequencing reveals a proliferative, "progenitor-like" population abundant in early embryonic stages that decreases to minimal levels postnatally. Furthermore, cardiac injury by ligation of the left anterior descending artery was found to activate cardiomyocyte proliferation in neonatal but not adult mice. Our data suggest that clonal dominance of differentiating progenitors mediates cardiac development, while a distinct subpopulation of cardiomyocytes may have the potential for limited proliferation during late embryonic development and shortly after birth. PMID- 29467411 TI - The impact of unrecorded readings on the precision and diagnostic performance of home blood pressure monitoring: a statistical study. AB - Hypertension is a major cardiovascular risk factor. To address the disease adequately, most clinicians rely on home blood pressure monitoring (HBPM). However, the impact of unrecorded BP values on the precision and diagnostic performance of BP schedules is unknown. We obtained 103 HBP patients schedules from a previous study. Then, readings were randomly removed from each schedule in order to create new incomplete schedules using a resampling technique. We obtained 10,000 new incomplete schedules. For each number of randomly removed readings, the percentages of incomplete schedules outside a systolic/diastolic blood pressure (SBP/DBP) range of 5/3 mmHg were calculated from the same complete patient's schedule. The sensitivity and specificity of incomplete HBPM schedules regarding BP control were also assessed. One hundred three HBPM schedules were analyzed. Mean patients' age was 67.9 +/- 9.9 years. In non-diabetic patients, the mean BP of complete schedules' means was 131.9 +/- 12.4/75.5 +/- 10.5. In diabetic patients, the mean BP of complete schedules' means was 135.5 +/- 14.0/73.4 +/- 8.2 mmHg. When schedules were composed of 14 and 21 random measures, differences over 5 mmHg were seen in 2.6% and 0.1% of non-diabetic patients' schedule and 3.7% and 0.1% of diabetic patients' schedule, respectively. At 21 measurements, sensitivity and specificity were approximately 95% and 98% in non-diabetic patients and 90% and 99% in non-diabetic patients, respectively. HBPM precision and diagnostic performance improve rapidly with accumulation of readings. Incomplete schedules composed of 21 readings can provide an almost perfect diagnostic tool compared with the complete schedule reference. PMID- 29467412 TI - IL-32 gamma reduces lung tumor development through upregulation of TIMP-3 overexpression and hypomethylation. AB - The low expression of tissue inhibitor of metalloproteinase 3 (TIMP-3) is important in inflammatory responses. Therefore, inhibition of TIMP-3 may promote tumor development. Our study showed that expression of TIMP-3 was elevated in lL 32gamma mice lung tissues. In this study, we investigated whether IL-32gamma mice inhibited lung tumor development through overexpression of TIMP-3 and its methylation. To explore the possible underlying mechanism, lung cancer cells were transfected with IL-32gamma cDNA plasmid. A marked increase in TIMP-3 expression was caused by promoter methylation. Mechanistic studies indicated that TIMP-3 overexpression reduced NF-kappaB activity, which led to cell growth inhibition in IL-32gamma transfected lung cancer cells. We also showed that IL-32gamma inhibits expression of DNA (cytosine-5-)-methyltransferase 1 (DNMT1). Moreover, IL-32gamma inhibits the binding of DNMT1 to TIMP-3 promoter, but this effect was reversed by the treatment of DNA methyltransferase inhibitor (5-Aza-CdR) and NF-kappaB inhibitor (PS1145), suggesting that a marked increase in TIMP-3 expression was caused by inhibition of promoter hypermethylation via decreased DNMT1 expression through the NF-kappaB pathway. In an in vivo carcinogen induced lung tumor model, tumor growth was inhibited in IL-32gamma overexpressed mice with elevated TIMP-3 expression and hypomethylation accompanied with reduced NF-kappaB activity. Moreover, in the lung cancer patient tissue, the expression of IL-32 and TIMP-3 was dramatically decreased at a grade-dependent manner compared to normal lung tissue. In summary, IL-32gamma may increase TIMP-3 expression via hypomethylation through inactivation of NF-kappaB activity, and thereby reduce lung tumor growth. PMID- 29467413 TI - Tunable Mechanical Metamaterials through Hybrid Kirigami Structures. AB - Inspired by the art of paper cutting, kirigami provides intriguing tools to create materials with unconventional mechanical and morphological responses. This behavior is appealing in multiple applications such as stretchable electronics and soft robotics and presents a tractable platform to study structure-property relationships in material systems. However, mechanical response is typically controlled through a single or fractal cut type patterned across an entire kirigami sheet, limiting deformation modes and tunability. Here we show how hybrid patterns of major and minor cuts creates new opportunities to introduce boundary conditions and non-prismatic beams to enable highly tunable mechanical responses. This hybrid approach reduces stiffness by a factor of ~30 while increasing ultimate strain by a factor of 2 (up to 750% strain) relative to single incision patterns. We present analytical models and generate general design criteria that is in excellent agreement with experimental data from nanoscopic to macroscopic systems. These hybrid kirigami materials create new opportunities for multifunctional materials and structures, which we demonstrate with stretchable kirigami conductors with nearly constant electrical resistance up to >400% strain and magnetoactive actuators with extremely rapid response (>10,000% strain s-1) and high, repeatable elongation (>300% strain). PMID- 29467414 TI - Induction of long-lived room temperature phosphorescence of carbon dots by water in hydrogen-bonded matrices. AB - Phosphorescence shows great potential for application in bioimaging and ion detection because of its long-lived luminescence and high signal-to-noise ratio, but establishing phosphorescence emission in aqueous environments remains a challenge. Herein, we present a general design strategy that effectively promotes phosphorescence by utilising water molecules to construct hydrogen-bonded networks between carbon dots (CDs) and cyanuric acid (CA). Interestingly, water molecules not only cause no phosphorescence quenching but also greatly enhance the phosphorescence emission. This enhancement behaviour can be explained by the fact that the highly ordered bound water on the CA particle surface can construct robust bridge-like hydrogen-bonded networks between the CDs and CA, which not only effectively rigidifies the C=O bonds of the CDs but also greatly enhances the rigidity of the entire system. In addition, the CD-CA suspension exhibits a high phosphorescence lifetime (687 ms) and is successfully applied in ion detection based on its visible phosphorescence. PMID- 29467415 TI - PARP1 and PARP2 stabilise replication forks at base excision repair intermediates through Fbh1-dependent Rad51 regulation. AB - PARP1 regulates the repair of DNA single-strand breaks generated directly, or during base excision repair (BER). However, the role of PARP2 in these and other repair mechanisms is unknown. Here, we report a requirement for PARP2 in stabilising replication forks that encounter BER intermediates through Fbh1 dependent regulation of Rad51. Whereas PARP2 is dispensable for tolerance of cells to SSBs or homologous recombination dysfunction, it is redundant with PARP1 in BER. Therefore, combined disruption of PARP1 and PARP2 leads to defective BER, resulting in elevated levels of replication-associated DNA damage owing to an inability to stabilise Rad51 at damaged replication forks and prevent uncontrolled DNA resection. Together, our results demonstrate how PARP1 and PARP2 regulate two independent, but intrinsically linked aspects of DNA base damage tolerance by promoting BER directly, and by stabilising replication forks that encounter BER intermediates. PMID- 29467416 TI - Long-distance propagation of short-wavelength spin waves. AB - Recent years have witnessed a rapidly growing interest in exploring the use of spin waves for information transmission and computation toward establishing a spin-wave-based technology that is not only significantly more energy efficient than the CMOS technology, but may also cause a major departure from the von Neumann architecture by enabling memory-in-logic and logic-in-memory architectures. A major bottleneck of advancing this technology is the excitation of spin waves with short wavelengths, which is a must because the wavelength dictates device scalability. Here, we report the discovery of an approach for the excitation of nm-wavelength spin waves. The demonstration uses ferromagnetic nanowires grown on a 20-nm-thick Y3Fe5O12 film strip. The propagation of spin waves with a wavelength down to 50 nm over a distance of 60,000 nm is measured. The measurements yield a spin-wave group velocity as high as 2600 m s-1, which is faster than both domain wall and skyrmion motions. PMID- 29467417 TI - Searching for an exotic spin-dependent interaction with a single electron-spin quantum sensor. AB - Searching for new particles beyond the standard model is crucial for understanding several fundamental conundrums in physics and astrophysics. Several hypothetical particles can mediate exotic spin-dependent interactions between ordinary fermions, which enable laboratory searches via the detection of the interactions. Most laboratory searches utilize a macroscopic source and detector, thus allowing the detection of interactions with submillimeter force range and above. It remains a challenge to detect the interactions at shorter force ranges. Here we propose and demonstrate that a near-surface nitrogen-vacancy center in diamond can be utilized as a quantum sensor to detect the monopole-dipole interaction between an electron spin and nucleons. Our result sets a constraint for the electron-nucleon coupling, [Formula: see text], with the force range 0.1 23 MUm. The obtained upper bound of the coupling at 20 MUm is [Formula: see text] < 6.24 * 10-15. PMID- 29467418 TI - Exogenous nitric oxide stimulates the odontogenic differentiation of rat dental pulp stem cells. AB - Nitric oxide (NO) is thought to play a pivotal regulatory role in dental pulp tissues under both physiological and pathological conditions. However, little is known about the NO functions in dental pulp stem cells (DPSCs). We examined the direct actions of a spontaneous NO gas-releasing donor, NOC-18, on the odontogenic capacity of rat DPSCs (rDPSCs). In the presence of NOC-18, rDPSCs were transformed into odontoblast-like cells with long cytoplasmic processes and a polarized nucleus. NOC-18 treatment increased alkaline phosphatase activity and enhanced dentin-like mineralized tissue formation and the expression levels of several odontoblast-specific genes, such as runt related factor 2, dentin matrix protein 1 and dentin sialophosphoprotein, in rDPSCs. In contrast, carboxy-PTIO, a NO scavenger, completely suppressed the odontogenic capacity of rDPSCs. This NO promoted odontogenic differentiation was activated by tumor necrosis factor-NF kappaB axis in rDPSCs. Further in vivo study demonstrated that NOC-18-application in a tooth cavity accelerated tertiary dentin formation, which was associated with early nitrotyrosine expression in the dental pulp tissues beneath the cavity. Taken together, the present findings indicate that exogenous NO directly induces the odontogenic capacity of rDPSCs, suggesting that NO donors might offer a novel host DPSC-targeting alternative to current pulp capping agents in endodontics. PMID- 29467420 TI - Direct DNA and RNA detection from large volumes of whole human blood. AB - PCR inhibitors in clinical specimens negatively affect the sensitivity of diagnostic PCR and RT-PCR or may even cause false-negative results. To overcome PCR inhibition, increase the sensitivity of the assays and simplify the detection protocols, simple methods based on quantitative nested real-time PCR and RT-PCR were developed to detect exogenous DNA and RNA directly from large volumes of whole human blood (WHB). Thermus thermophilus (Tth) polymerase is resistant to several common PCR inhibitors and exhibits reverse transcriptase activity in the presence of manganese ions. In combination with optimized concentrations of magnesium ions and manganese ions, Tth polymerase enabled efficient detection of DNA and RNA from large volumes of WHB treated with various anticoagulants. The applicability of these methods was further demonstrated by examining WHB specimens collected from different healthy individuals and those stored under a variety of conditions. The detection limit of these methods was determined by detecting exogenous DNA, RNA, and bacteria spiked in WHB. To the best of our knowledge, direct RNA detection from large volumes of WHB has not been reported. The results of the developed methods can be obtained within 4 hours, making them possible for rapid and accurate detection of disease-causing agents from WHB. PMID- 29467419 TI - A neuronal mechanism underlying decision-making deficits during hyperdopaminergic states. AB - Hyperdopaminergic states in mental disorders are associated with disruptive deficits in decision making. However, the precise contribution of topographically distinct mesencephalic dopamine pathways to decision-making processes remains elusive. Here we show, using a multidisciplinary approach, how hyperactivity of ascending projections from the ventral tegmental area (VTA) contributes to impaired flexible decision making in rats. Activation of the VTA-nucleus accumbens pathway leads to insensitivity to loss and punishment due to impaired processing of negative reward prediction errors. In contrast, activation of the VTA-prefrontal cortex pathway promotes risky decision making without affecting the ability to choose the economically most beneficial option. Together, these findings show how malfunction of ascending VTA projections affects value-based decision making, suggesting a potential mechanism through which increased forebrain dopamine signaling leads to aberrant behavior, as is seen in substance abuse, mania, and after dopamine replacement therapy in Parkinson's disease. PMID- 29467421 TI - Application of kernel principal component analysis and computational machine learning to exploration of metabolites strongly associated with diet. AB - Computer-based technological innovation provides advancements in sophisticated and diverse analytical instruments, enabling massive amounts of data collection with relative ease. This is accompanied by a fast-growing demand for technological progress in data mining methods for analysis of big data derived from chemical and biological systems. From this perspective, use of a general "linear" multivariate analysis alone limits interpretations due to "non-linear" variations in metabolic data from living organisms. Here we describe a kernel principal component analysis (KPCA)-incorporated analytical approach for extracting useful information from metabolic profiling data. To overcome the limitation of important variable (metabolite) determinations, we incorporated a random forest conditional variable importance measure into our KPCA-based analytical approach to demonstrate the relative importance of metabolites. Using a market basket analysis, hippurate, the most important variable detected in the importance measure, was associated with high levels of some vitamins and minerals present in foods eaten the previous day, suggesting a relationship between increased hippurate and intake of a wide variety of vegetables and fruits. Therefore, the KPCA-incorporated analytical approach described herein enabled us to capture input-output responses, and should be useful not only for metabolic profiling but also for profiling in other areas of biological and environmental systems. PMID- 29467422 TI - Luminescent and paramagnetic properties of nanoparticles shed light on their interactions with proteins. AB - Nanoparticles have been recognized as promising tools for targeted drug-delivery and protein therapeutics. However, the mechanisms of protein-nanoparticle interaction and the dynamics underlying the binding process are poorly understood. Here, we present a general methodology for the characterization of protein-nanoparticle interaction on a molecular level. To this end we combined biophysical techniques including nuclear magnetic resonance (NMR), circular dichroism (CD), resonance energy transfer (RET) and surface plasmon resonance (SPR). Particularly, we analyzed molecular mechanisms and dynamics of the interaction of CaF2 nanoparticles with the prototypical calcium sensor calmodulin (CaM). We observed the transient formation of an intermediate encounter complex involving the structural region linking the two domains. Specific interaction of CaM with CaF2 NPs is driven by the N-terminal EF-hands, which seem to recognize Ca2+ on the surface of the nanoparticle. We conclude that CaF2 NP-CaM interaction is fully compatible with potential applications in nanomedicine. Overall, the methods presented in this work can be extended to other systems and may be useful to quantitatively characterize structural and dynamic features of protein-NP interactions with important implications for nanomedicine and nano-biotechnology. PMID- 29467423 TI - Transcriptome changes induced by abiotic stresses in Artemisia annua. AB - Artemisia annua is known to be the source of artemisinin worldwide which is an antimalarial compound but is synthesised in very limited amount in the plant. Most research laid emphasis on the methods of enhancing artemisinin but our study has been planned in a way that it may simultaneously address two problems encountered by the plant. Firstly, to know the effect on the artemisinin content in the era of climate change because the secondary metabolites tend to increase under stress. Secondly, to identify some of the stress responsive genes that could help in stress tolerance of the plant under abiotic stress. Hence, the A. annua plants were subjected to four abiotic stresses (salt, cold, drought and water-logging) and it was observed that the artemisinin content increased in all the stress conditions except drought. Next, in order to identify the stress responsive genes, the transcriptome sequencing of the plants under stress was carried out resulting in 89,362 transcripts for control and 81,328, 76,337, 90,470 and 96,493 transcripts for salt, cold, drought, and water logging stresses. This investigation provides new insights for functional studies of genes involved in multiple abiotic stresses and potential candidate genes for multiple stress tolerance in A. annua. PMID- 29467424 TI - Spin canting across core/shell Fe3O4/MnxFe3-xO4 nanoparticles. AB - Magnetic nanoparticles (MNPs) have become increasingly important in biomedical applications like magnetic imaging and hyperthermia based cancer treatment. Understanding their magnetic spin configurations is important for optimizing these applications. The measured magnetization of MNPs can be significantly lower than bulk counterparts, often due to canted spins. This has previously been presumed to be a surface effect, where reduced exchange allows spins closest to the nanoparticle surface to deviate locally from collinear structures. We demonstrate that intraparticle effects can induce spin canting throughout a MNP via the Dzyaloshinskii-Moriya interaction (DMI). We study ~7.4 nm diameter, core/shell Fe3O4/MnxFe3-xO4 MNPs with a 0.5 nm Mn-ferrite shell. Mossbauer spectroscopy, x-ray absorption spectroscopy and x-ray magnetic circular dichroism are used to determine chemical structure of core and shell. Polarized small angle neutron scattering shows parallel and perpendicular magnetic correlations, suggesting multiparticle coherent spin canting in an applied field. Atomistic simulations reveal the underlying mechanism of the observed spin canting. These show that strong DMI can lead to magnetic frustration within the shell and cause canting of the net particle moment. These results illuminate how core/shell nanoparticle systems can be engineered for spin canting across the whole of the particle, rather than solely at the surface. PMID- 29467425 TI - Genome-scale examination of NBS-encoding genes in blueberry. AB - Blueberry is an important crop worldwide. It is, however, susceptible to a variety of diseases, which can lead to losses in yield and fruit quality. Although screening studies have identified resistant germplasm for some important diseases, still little is known about the molecular basis underlying that resistance. The most predominant type of resistance (R) genes contains nucleotide binding site and leucine rich repeat (NBS-LRR) domains. The identification and characterization of such a gene family in blueberry would enhance the foundation of knowledge needed for its genetic improvement. In this study, we searched for and found a total of 106 NBS-encoding genes (including 97 NBS-LRR) in the current blueberry genome. The NBS genes were grouped into eleven distinct classes based on their domain architecture. More than 22% of the NBS genes are present in clusters. Ten genes were mapped onto seven linkage groups. Phylogenetic analysis grouped these genes into two major clusters based on their structural variation, the first cluster having toll and interleukin-1 like receptor (TIR) domains and most of the second cluster containing a coiled-coil domain. Our study provides new insight into the NBS gene family in blueberry and is an important resource for the identification of functional R-genes. PMID- 29467426 TI - Neuronal avalanche dynamics indicates different universality classes in neuronal cultures. AB - Neuronal avalanches have become an ubiquitous tool to describe the activity of large neuronal assemblies. The emergence of scale-free statistics with well defined exponents has led to the belief that the brain might operate near a critical point. Yet not much is known in terms of how the different exponents arise or how robust they are. Using calcium imaging recordings of dissociated neuronal cultures we show that the exponents are not universal, and that significantly different exponents arise with different culture preparations, leading to the existence of different universality classes. Naturally developing cultures show avalanche statistics consistent with those of a mean-field branching process, however, cultures grown in the presence of folic acid metabolites appear to be in a distinct universality class with significantly different critical exponents. Given the increased synaptic density and number of feedback loops in folate reared cultures, our results suggest that network topology plays a leading role in shaping the avalanche dynamics. We also show that for both types of cultures pronounced correlations exist in the sizes of neuronal avalanches indicating size clustering, being much stronger in folate reared cultures. PMID- 29467428 TI - Dynamic air/liquid pockets for guiding microscale flow. AB - Microscale flows of fluids are mainly guided either by solid matrices or by liquid-liquid interfaces. However, the solid matrices are plagued with persistent fouling problems, while liquid-liquid interfaces are limited to low-pressure applications. Here we report a dynamic liquid/solid/gas material containing both air and liquid pockets, which are formed by partially infiltrating a porous matrix with a functional liquid. Using detailed theoretical and experimental data, we show that the distribution of the air- and liquid-filled pores is responsive to pressure and enables the formation and instantaneous recovery of stable liquid-liquid interfaces that sustain a wide range of pressures and prevent channel contamination. This adaptive design is demonstrated for polymeric materials and extended to metal-based systems that can achieve unmatched mechanical and thermal stability. Our platform with its unique adaptive pressure and antifouling capabilities may offer potential solutions to flow control in microfluidics, medical devices, microscale synthesis, and biological assays. PMID- 29467427 TI - High-efficiency RNA-based reprogramming of human primary fibroblasts. AB - Induced pluripotent stem cells (iPSCs) hold great promise for regenerative medicine; however, their potential clinical application is hampered by the low efficiency of somatic cell reprogramming. Here, we show that the synergistic activity of synthetic modified mRNAs encoding reprogramming factors and miRNA 367/302s delivered as mature miRNA mimics greatly enhances the reprogramming of human primary fibroblasts into iPSCs. This synergistic activity is dependent upon an optimal RNA transfection regimen and culturing conditions tailored specifically to human primary fibroblasts. As a result, we can now generate up to 4,019 iPSC colonies from only 500 starting human primary neonatal fibroblasts and reprogram up to 90.7% of individually plated cells, producing multiple sister colonies. This methodology consistently generates clinically relevant, integration-free iPSCs from a variety of human patient's fibroblasts under feeder free conditions and can be applicable for the clinical translation of iPSCs and studying the biology of reprogramming. PMID- 29467429 TI - A Genetic Screen for Investigating the Human Lysosomal CystineTransporter, Cystinosin. AB - Cystinosin, a lysosomal transporter is involved in the efflux of cystine from the lysosome to the cytosol. Mutations in the human cystinosin gene (CTNS) cause cystinosis, a recessive autosomal disorder. Studies on cystinosin have been limited by the absence of a robust genetic screen. In the present study we have developed a dual strategy for evaluating cystinosin function that is amenable to rapid genetic analysis. We show that human cystinosin expressed in this yeast confers growth on cystine when the protein is mistargeted to the plasma membrane by the deletion of the C-terminal targeting signal, GYQDL. We also screened a vacuolar protein sorting deletion library, and subsequently created multiple vps deletion mutants for kinetic studies. The double deletion, vps1Deltavps17Delta, greatly enhanced uptake. This enabled validation by kinetic studies, including first studies on the WT CTNS protein (that contained the GYQDL motif). Using this screen we isolated several gain of function mutants, G131S/D, G309S/D, A137V, G197R, S270T, L274F and S312N showing enhanced growth on low concentrations of cystine. Kinetic analysis yielded insights into the role of the residues (including one of the patient mutations, G197R). The results indicate that the screen could be effectively used for interrogating and understanding the CTNS protein. PMID- 29467430 TI - Evaluation of Macaca radiata as a non-human primate model of Dengue virus infection. AB - Dengue virus (DENV) causes a wide range of illnesses in humans, including dengue fever and dengue haemorrhagic fever. Current animal models of DENV infection are limited for understanding infectious diseases in humans. Bonnet monkeys (Macaca radiata), a type of Old World monkey, have been used to study experimental and natural infections by flaviviruses, but Old World monkeys have not yet been used as DENV infection models. In this study, the replication levels of several DENV strains were evaluated using peripheral blood mononuclear cells. Our findings indicated that DENV-4 09-48 strain, isolated from a traveller returning from India in 2009, was a highly replicative virus. Three bonnet monkeys were infected with 09-48 strain and antibody responses were assessed. DENV nonstructural protein 1 antigen was detected and high viraemia was observed. These results indicated that bonnet monkeys and 09-48 strain could be used as a reliable primate model for the study of DENV. PMID- 29467431 TI - Hypoxia-induced long non-coding RNA Malat1 is dispensable for renal ischemia/reperfusion-injury. AB - Renal ischemia-reperfusion (I/R) injury is a major cause of acute kidney injury (AKI). Non-coding RNAs are crucially involved in its pathophysiology. We identified hypoxia-induced long non-coding RNA Malat1 (Metastasis Associated Lung Adenocarcinoma Transcript 1) to be upregulated in renal I/R injury. We here elucidated the functional role of Malat1 in vitro and its potential contribution to kidney injury in vivo. Malat1 was upregulated in kidney biopsies and plasma of patients with AKI, in murine hypoxic kidney tissue as well as in cultured and ex vivo sorted hypoxic endothelial cells and tubular epithelial cells. Malat1 was transcriptionally activated by hypoxia-inducible factor 1-alpha. In vitro, Malat1 inhibition reduced proliferation and the number of endothelial cells in the S phase of the cell cycle. In vivo, Malat1 knockout and wildtype mice showed similar degrees of outer medullary tubular epithelial injury, proliferation, capillary rarefaction, inflammation and fibrosis, survival and kidney function. Small-RNA sequencing and whole genome expression analysis revealed only minor changes between ischemic Malat1 knockout and wildtype mice. Contrary to previous studies, which suggested a prominent role of Malat1 in the induction of disease, we did not confirm an in vivo role of Malat1 concerning renal I/R-injury. PMID- 29467432 TI - Printed Receive Coils with High Acoustic Transparency for Magnetic Resonance Guided Focused Ultrasound. AB - In magnetic resonance guided focused ultrasound (MRgFUS) therapy sound waves are focused through the body to selectively ablate difficult to access lesions and tissues. A magnetic resonance imaging (MRI) scanner non-invasively tracks the temperature increase throughout the tissue to guide the therapy. In clinical MRI, tightly fitted hardware comprised of multichannel coil arrays are required to capture high quality images at high spatiotemporal resolution. Ablating tissue requires a clear path for acoustic energy to travel but current array materials scatter and attenuate acoustic energy. As a result coil arrays are placed outside of the transducer, clear of the beam path, compromising imaging speed, resolution, and temperature accuracy of the scan. Here we show that when coil arrays are fabricated by additive manufacturing (i.e., printing), they exhibit acoustic transparency as high as 89.5%. This allows the coils to be placed in the beam path increasing the image signal to noise ratio (SNR) five-fold in phantoms and volunteers. We also characterize printed coil materials properties over time when submerged in the water required for acoustic coupling. These arrays offer high SNR and acceleration capabilities, which can address current challenges in treating head and abdominal tumors allowing MRgFUS to give patients better outcomes. PMID- 29467433 TI - Trend and risk factors of low birth weight and macrosomia in south China, 2005 2017: a retrospective observational study. AB - The percentages of low birth weight (LBW) increased from 7.7% in 2005 to 11.3% in 2011 and declined to 8.1% in 2017. For very low birth weight (VLBW) individuals, the proportion declined -1.0% annually, from 2.5% in 2005 to 1.4% in 2017. Among moderately low birth weight (MLBW) individuals, the proportion first increased 12.8% annually, from 5.0% in 2005 to 9.3% in 2011, and then declined -3.8% annually, from 9.4% in 2011 to 7.0% in 2017. The percentages of macrosomia monotone decreased from 4.0% in 2005 to 2.5% in 2017, an annual decline of -4.0%. Multiple regression analyses showed that boys, maternal age, hypertensive disorders complicating pregnancy (HDCP), and diabetes were significant risk factors for LBW. Boys, maternal age, gestational age, HDCP, diabetes, and maternal BMI were significant risk factors for macrosomia. Although the relevant figures declined slightly in our study, it is likely that LBW and macrosomia will remain a major public health issue over the next few years in China. More research aimed at control and prevention of these risk factors for LBW and macrosomia and their detrimental outcome in the mother and perinatal child should be performed in China. PMID- 29467434 TI - Conformational IgE Epitope Mapping of Der p 2 and the Evaluations of Two Candidate Hypoallergens for Immunotherapy. AB - Epitope mapping of Der p 2, a clinically important dust-mite allergen is the first step in designing immunotherapy hypoallergen vaccine candidates. Twenty-one single alanine mutants of Der p 2 were generated and their secondary structure was analysed using circular dichroism spectra. Only one mutant, K96A resulted in a misfolded protein. All mutants were tested for serum IgE reactivity using serum from dust mite allergic individuals by immuno dot-blots. Mutations to five residues, N10, E25, K77, K96 and E102 consistently showed reduced IgE reactions compared to wild-type Der p 2, and therefore these residues constitute the major IgE epitopes of Der p 2. Two mutants with consistent low IgE binding, K96A and E102A, were subsequently evaluated as hypoallergen candidates. IgG antibodies raised in mice against both mutants could inhibit human IgE-binding to WT Der p 2. Both mutants had intact T-cell epitopes as they were able to stimulate peripheral blood mononuclear cell proliferation similar to WT Der p 2. However, a switch in Th1:Th2 cytokine profile was not observed. In summary, we have identified the major conformational epitopes of Der p 2, and evaluated two Der p 2 hypoallergen vaccine candidates for immunotherapy. PMID- 29467435 TI - Visualisation of DCP, a nerve agent mimic, in Catfish brain by a simple chemosensor. AB - A chemosensor, 3-aminophenol-based rhodamine conjugate (ARC) has been developed for visualisation of diethylchlorophosphate (DCP), mimic of a chemical warfare agent, in Catfish brain. The simple detection of DCP by "turn-on" fluorescence property of the chemosensor makes it unique for easy and rapid in vivo and in vitro detection of DCP with the detection limit of 5.6 nM.

AB - Tissue engineering has significantly contributed to the development of optimal treatments for individual injury sites based on their unique functional and histologic properties. Human organs and tissue have three-dimensional (3D) morphologies; for example, the morphology of the eye is a spherical shape. However, most conventional electrospinning equipment is only capable of fabricating a two-dimensional (2D) structured fibrous scaffold and no report is available on a 3D electrospinning method to fabricate a hemispherical scaffold to mimic the native properties of the cornea, including microscopic to macroscopic morphology and transparency. We proposed a novel electrospinning method using a single nonconductive hemispherical device and a metal pin. A designed peg-top shaped collector, a hemispherical nonconductive device with a metal pin in the center and copper wire forming a circle around at the edge was attached to a conventional conductive collector. A 3D hemispherical transparent scaffold with radially aligned nanofibers was successfully fabricated with the designed peg-top collector. In summary, our fabricated 3D electrospun scaffold is expected to be suitable for the treatment of injuries of ocular tissues owing to the hemispherical shape and radially aligned nanofibers which can guide the direction of the main collagen and cellular actin filament in the extracellular matrix.

AB - Repetitive transcranial magnetic stimulation (rTMS) is increasingly used clinically in the treatment of patients with major depressive disorder (MDD). However, rTMS treatment response can be slow. Early research suggests that accelerated forms of rTMS may be effective but no research has directly evaluated a schedule of accelerated rTMS compared to standard rTMS. To assess the efficacy of accelerated rTMS compared to standard daily rTMS., 115 outpatients with MDD received either accelerated rTMS (n = 58) (i.e., 63,000 high frequency rTMS pulses delivered as 3 treatments per day over 3 days in week 1, 3 treatments over 2 days in week 2 and 3 treatments on a single day in week 3) or standard rTMS (n = 57) (i.e., 63,000 total high frequency rTMS pulses delivered over 5 days per week for 4 weeks) following randomization. There were no significant differences in remission or response rates (p > 0.05 for all analyses) or reduction in depression scores (Time by group interaction (F (5, 489.452) = 1.711, p = 0.130) between the accelerated and standard rTMS treatment groups. Accelerated treatment was associated with a higher rate of reported treatment discomfort. It is feasible to provide accelerated rTMS treatment for outpatients with depression and this is likely to produce meaningful antidepressant effects.

There, binary bits are carried by nanoscale spin swirls-skyrmions-driven along magnetic strips. Stability of the skyrmions is a critical issue for realising this technology. Here we demonstrate that the racetrack skyrmion lifetime can be calculated from first principles as a function of temperature, magnetic field and track width. Our method combines harmonic transition state theory extended to include Goldstone modes, with an atomistic spin Hamiltonian parametrized from density functional theory calculations. We demonstrate that two annihilation mechanisms contribute to the skyrmion stability: At low external magnetic field, escape through the track boundary prevails, but a crossover field exists, above which the collapse in the interior becomes dominant. Considering a Pd/Fe bilayer on an Ir(111) substrate as a well-established model system, the calculated skyrmion lifetime is found to be consistent with reported experimental measurements. Our simulations also show that the Arrhenius pre-exponential factor of escape depends only weakly on the external magnetic field, whereas the pre exponential factor for collapse is strongly field dependent. Our results open the door for predictive simulations, free from empirical parameters, to aid the design of skyrmion-based information technology.

AB - Bioceramic particulates capable of filling bone defects have gained considerable interest over the last decade. Herein, dual-shell bioceramic microspheres (CaP@CaSi@CaP, CaSi@CaP@CaSi) with adjustable beta-tricalcium phosphate (CaP) and beta-calcium silicate (CaSi) distribution were fabricated using a co-concentric capillary system enabling bone repair via a tailorable biodegradation process. The in vitro results showed the optimal concentration (1/16 of 200 mg/ml) of extracts of dual-shell microspheres could promote bone marrow mesenchymal cell (BMSC) proliferation and enhance the level of ALP activity and Alizarin Red staining. The in vivo bone repair and microsphere biodegradation in calvarial bone defects were compared using micro-computed tomography and histological evaluations. The results indicated the pure CaP microspheres were minimally resorbed at 18 weeks post-operatively and new bone tissue was limited; however, the dual-shell microspheres were appreciably biodegraded with time in accordance with the priority from CaSi to CaP in specific layers. The CaSi@CaP@CaSi group showed a significantly higher ability to promote bone regeneration than the CaP@CaSi@CaP group. This study indicates that the biphasic microspheres with adjustable composition distribution are promising for tailoring material degradation and bone regeneration rate, and such versatile design strategy is thought to fabricate various advanced biomaterials with tailorable biological performances for bone reconstruction. PMID- 29467440 TI - Metabolic profile associated with distinct behavioral coping strategies of 129Sv and Bl6 mice in repeated motility test. AB - We investigated the metabolic outcome of different coping strategies in 129S6/SvEvTac (129Sv) and C57BL/6Ntac (Bl6) strains. Two different batches of male 129Sv and Bl6 mice were used. One batch was not subjected to any behavioral manipulations (home cage control; HCC), whereas the other batch was treated with saline for 11 days and exposed after every treatment to the motor activity measurement (repeated motility tested; RMT). Bl6 RMT mice displayed a robust increase in number of rearings during repeated testing. 129Sv RMT mice experienced significant loss of body weight, but showed enhanced weight gain in HCC batch compared to Bl6. Serum metabolites (acylcarnitines, amino acids, biogenic amines, hexoses, glycerophospholipids and sphingolipids) were determined with AbsoluteIDQ p180 kit. Results of the metabolomic study revealed prominent peculiarities between strains in two different conditions. Comparison of both batches of mice demonstrated that in Bl6 biogenic amines (acetyl-ornithine, alpha amionadipic acid, carnosine) and lysophosphatidylcholine PC(16:1/0:0) dominated. However in 129Sv acylcarnitine C5 clearly dominated, indicating shift towards short-chain acylcarnitines. Stable strain-specific ratios also emerged for both lines, ratio of glycine/PC ae C38:2 for Bl6 and ratios of C5/C0 as well as PC(16:0/0:0)/PC(16:1/0:0) for 129Sv. The described metabolic changes probably reflect different behavioral coping strategies of 129Sv and Bl6 mice. PMID- 29467441 TI - LINC01016 promotes the malignant phenotype of endometrial cancer cells by regulating the miR-302a-3p/miR-3130-3p/NFYA/SATB1 axis. AB - Long noncoding RNAs (lncRNAs) have been implicated in tumorigenesis and cancer progression and are tightly associated with the phenotypes of numerous cancers. However, the functional roles underlying these effects are unknown. The expression levels of LINC01016, miR-302a-3p, miR-3130-3p, NFYA, and SATB1 were evaluated by quantitative real-time polymerase chain reaction (qRT-PCR) in 33 endometrial cancer tissues and 20 normal tissues. Bioinformatics analyses, luciferase reporter analyses, chromatin immunoprecipitation (ChIP) assays, and qRT-PCR assays were performed to verify potential binding sites. The qRT-PCR and western blot were used to identify the regulatory mechanisms of LINC01016 in cell biological behavior, which were also examined by cell counting kit -8 (CCK-8), 5 ethynyl-2'-deoxyuridine (EdU) assays, flow cytometry, wound healing assays, and transwell assays. LINC01016 was substantially upregulated in endometrial cancer tissues, and LINC01016 silencing abolished the malignant behavior of endometrial cancer cells. LINC01016 positively rescued the downstream gene nuclear factor YA (NFYA) by competitively "sponging" miR-302a-3p and miR-3130-3p. In turn, these two miRNAs could inhibit LINC01016 transcription, thus forming two reciprocal repression cycles, which influenced the biological behavior of endometrial cancer cells. MiR-302a-3p and miR-3130-3p could specifically bind with the 3'-UTR regions of NFYA, and NFYA could upregulate the expression of special AT-rich sequence-binding protein 1 (SATB1) as a transcriptional factor. This study was the first to show that the LINC01016-miR-302a-3p/miR-3130-3p/NFYA/SATB1 axis played a crucial role in the occurrence of endometrial cancer. These findings may provide relevant insights into the diagnosis and therapy of endometrial cancer. PMID- 29467442 TI - The influence of riverine barriers, climate, and topography on the biogeographic regionalization of Amazonian anurans. AB - We evaluated five non-mutually exclusive hypotheses driving the biogeographic regions of anuran species in the Amazonia. We overlaid extent-of-occurrence maps for anurans 50 * 50 km cells to generate a presence-absence matrix. This matrix was subjected to a cluster analysis to identify the pattern and number of biogeographic regions for the dataset. Then, we used multinomial logistic regression models and deviance partitioning to explore the relative importance of contemporary and historical climate variables, topographic complexity, riverine barriers and vegetation structure in explaining the biogeographic regions identified. We found seven biogeographic regions for anurans in the Amazonia. The major rivers in the Amazonia made the largest contribution to explaining the variability in anuran biogeographic regions, followed by climate variables and topography. The barrier effect seems to be strong for some rivers, such as the Amazon and Madeira, but other Amazonia rivers appear to not be effective barriers. Furthermore, climate and topographical variables provide an environmental gradient driving the species richness and anuran range-size distributions. Therefore, our results provide a spatially explicit framework that could be used to address conservation and management issues of anuran diversity for the largest tropical forests in the world. PMID- 29467443 TI - Emerging views of the nucleus as a cellular mechanosensor. AB - The ability of cells to respond to mechanical forces is critical for numerous biological processes. Emerging evidence indicates that external mechanical forces trigger changes in nuclear envelope structure and composition, chromatin organization and gene expression. However, it remains unclear if these processes originate in the nucleus or are downstream of cytoplasmic signals. Here we discuss recent findings that support a direct role of the nucleus in cellular mechanosensing and highlight novel tools to study nuclear mechanotransduction. PMID- 29467444 TI - Evaluation of digital real-time PCR assay as a molecular diagnostic tool for single-cell analysis. AB - In a single-cell study, isolating and identifying single cells are essential, but these processes often require a large investment of time or money. The aim of this study was to isolate and analyse single cells using a novel platform, the PanelChipTM Analysis System, which includes 2500 microwells chip and a digital real-time polymerase chain reaction (dqPCR) assay, in comparison with a standard PCR (qPCR) assay. Through the serial dilution of a known concentration standard, namely pUC19, the accuracy and sensitivity levels of two methodologies were compared. The two systems were tested on the basis of expression levels of the genetic markers vimentin, E-cadherin, N-cadherin and GAPDH in A549 lung carcinoma cells at two known concentrations. Furthermore, the influence of a known PCR inhibitor commonly found in blood samples, heparin, was evaluated in both methodologies. Finally, mathematical models were proposed and separation method of single cells was verified; moreover, gene expression levels during epithelial mesenchymal transition in single cells under TGFbeta1 treatment were measured. The drawn conclusion is that dqPCR performed using PanelChipTM is superior to the standard qPCR in terms of sensitivity, precision, and heparin tolerance. The dqPCR assay is a potential tool for clinical diagnosis and single-cell applications. PMID- 29467445 TI - Vaccine-induced antigen-specific regulatory T cells attenuate the antiviral immunity against acute influenza virus infection. AB - Peptide-based T cell vaccines targeting the conserved epitopes of influenza virus can provide cross-protection against distantly related strains, but they are generally not immunogenic. Foreign antigen-specific regulatory T (Treg) cells are induced under subimmunogenic conditions peripherally, although their development and role in vaccine-mediated antiviral immunity is unclear. Here, we demonstrated primary vaccination with peptides alone significantly induced antigen-specific Foxp3+ Treg cells, which were further expanded by repeated vaccination with unadjuvanted peptides. Certain adjuvants, including CpG, suppressed the induction and expansion of antigen-specific Treg cells by peptide vaccination. Interestingly, secondary influenza virus infection significantly increased the frequency of preexisting antigen-specific Treg cells, although primary infection barely induced them. Importantly, specific depletion of vaccine-induced antigen specific Treg cells promoted influenza viral clearance, indicating their inhibitory role in vivo. Immunization with CpG-adjuvanted peptides by the subcutaneous prime-intranasal-boost strategy restricted the recruitment and accumulation of antigen-specific Treg cells in lung, and stimulated robust T cell immunity. Finally, subcutaneous prime-intranasal-boost immunization with CpG adjuvanted peptides or whole-inactivated influenza vaccines protected mice from heterosubtypic influenza virus infection. In conclusion, antigen-specific Treg cells induced by peptide vaccines attenuate the antiviral immunity against influenza virus infection. CpG-adjuvanted peptide vaccines provide heterosubtypic influenza protection probably by inhibiting Treg development and enhancing T cell immunity. PMID- 29467446 TI - Oral cholera vaccination promotes homing of IgA+ memory B cells to the large intestine and the respiratory tract. AB - Oral cholera vaccination is used to induce immune responses in the intestines to protect against cholera infection. However, oral vaccination may also affect immune responses in other mucosal tissues. To study this, tissue-specific homing potential and kinetics of B-cell responses were characterized after oral cholera vaccination. Healthy adult volunteers received two doses of Dukoral(r) and blood, saliva, nasal wash, and fecal samples were collected over time to detect vaccine specific antibodies. Additionally, homing potential of lymphocytes to small intestine, colon, airways, skin, and periphery was measured by expression of Integrin beta1 and beta7, CCR9, CCR10, CCR7, and CLA. After vaccination, antibody responses to cholera toxin B (CTB) and Dukoral(r) were detected in serum and nasal wash. CTB-specific memory B cells in peripheral blood and tissue homing profiles of memory B cells peaked at day 18. IgA+ memory B cells expressed markers that enable homing to the airways and colon, while IgA- memory B cells primarily expressed small-intestine-homing markers. These data show that oral cholera vaccination has a differential effect on immune responses in various mucosal sites, including the respiratory tract. PMID- 29467447 TI - Notch signaling represents an important checkpoint between follicular T-helper and canonical T-helper 2 cell fate. AB - Type-2 immunity is regulated by two distinct CD4+ T-cell subsets. T follicular helper (Tfh) cells are required for humoral hallmarks of type-2 inflammation. T helper type-2 (Th2) cells orchestrate type-2 inflammation in peripheral tissues, such as the lung and intestine. Given the importance of Notch signaling in the establishment of other CD4+ T-helper cell subsets, we investigated whether canonical Notch activation could differentially impact Tfh and Th2 cell fate during the induction of type-2 immunity. These studies show that Tfh cell, but not Th2 cell, generation and function is reliant on Notch signaling. While early Tfh cell specification is influenced by functional Notch ligands on classical dendritic cells, functional Notch ligands on cells other than dendritic cells, T cells, B cells, and follicular dendritic cells are sufficient to achieve full Tfh cell commitment. These findings identify Notch signaling as an early lineage determining factor between Tfh and Th2 cell fate. PMID- 29467449 TI - Systemic lupus erythematosus: Antihypertensive drug has dual effects. PMID- 29467448 TI - Identification of the fungal ligand triggering cytotoxic PRR-mediated NK cell killing of Cryptococcus and Candida. AB - Natural killer (NK) cells use the activating receptor NKp30 as a microbial pattern-recognition receptor to recognize, activate cytolytic pathways, and directly kill the fungi Cryptococcus neoformans and Candida albicans. However, the fungal pathogen-associated molecular pattern (PAMP) that triggers NKp30 mediated killing remains to be identified. Here we show that beta-1,3-glucan, a component of the fungal cell wall, binds to NKp30. We further demonstrate that beta-1,3-glucan stimulates granule convergence and polarization, as shown by live cell imaging. Through Src Family Kinase signaling, beta-1,3-glucan increases expression and clustering of NKp30 at the microbial and NK cell synapse to induce perforin release for fungal cytotoxicity. Rather than blocking the interaction between fungi and NK cells, soluble beta-1,3-glucan enhances fungal killing and restores defective cryptococcal killing by NK cells from HIV-positive individuals, implicating beta-1,3-glucan to be both an activating ligand and a soluble PAMP that shapes NK cell host immunity.

PMID- 29467456 TI - Genome-wide CRISPR screen reveals SGOL1 as a druggable target of sorafenib treated hepatocellular carcinoma. AB - The genome-wide clustered regularly interspaced short palindromic repeats (CRISPR) screen is a powerful tool used to identify therapeutic targets that can be harnessed for cancer treatment. This study aimed to assess the efficacy of genome-wide CRISPR screening to identify druggable genes associated with sorafenib-treated hepatocellular carcinoma (HCC). A genome-scale CRISPR knockout (GeCKO v2) library containing 123,411 single guide RNAs (sgRNAs) was used to identify loss-of-function mutations conferring sorafenib resistance upon HCC cells. Resistance gene screens identified SGOL1 as an indicator of prognosis of patients treated with sorafenib. Of the 19,050 genes tested, the knockout screen identified inhibition of SGOL1 expression as the most-effective genetic suppressor of sorafenib activity. Analysis of the survival of 210 patients with HCC after hepatic resection revealed that high SGOL1 expression shortened overall survival (P = 0.021). Further, matched pairs analysis of the TCGA database revealed that SGOL1 is differentially expressed. When we used a lentivirus Cas9 vector to determine the effect of targeting SGOL1 with a specific sgRNA in HCC cells, we found that SGOL1 expression was efficiently inhibited and that loss of SGOL1 was associated with sorafenib resistance. Further, loss of SGOL1 from HCC cell decreased the cytotoxicity of sorafenib in vivo. We conclude that the CRISPR screen is a powerful tool for therapeutic target analysis of sorafenib treatment and that SGOL1 serves as a druggable target for HCC treated with sorafenib and an indicator of prognosis. PMID- 29467455 TI - Lack of cystic fibrosis transmembrane conductance regulator disrupts fetal airway development in pigs. AB - Loss of cystic fibrosis transmembrane conductance regulator (CFTR) function causes cystic fibrosis (CF), predisposing the lungs to chronic infection and inflammation. In young infants with CF, structural airway defects are increasingly recognized before the onset of significant lung disease, which suggests a developmental origin and a possible role in lung disease pathogenesis. The role(s) of CFTR in lung development is unclear and developmental studies in humans with CF are not feasible. Young CF pigs have structural airway changes and develop spontaneous postnatal lung disease similar to humans; therefore, we studied lung development in the pig model (non-CF and CF). CF trachea and proximal airways had structural lesions detectable as early as pseudoglandular development. At this early developmental stage, budding CF airways had smaller, hypo-distended lumens compared to non-CF airways. Non-CF lung explants exhibited airway lumen distension in response to forskolin/IBMX as well as to fibroblast growth factor (FGF)-10, consistent with CFTR-dependent anion transport/secretion, but this was lacking in CF airways. We studied primary pig airway epithelial cell cultures and found that FGF10 increased cellular proliferation (non-CF and CF) and CFTR expression/function (in non-CF only). In pseudoglandular stage lung tissue, CFTR protein was exclusively localized to the leading edges of budding airways in non-CF (but not CF) lungs. This discreet microanatomic localization of CFTR is consistent with the site, during branching morphogenesis, where airway epithelia are responsive to FGF10 regulation. In summary, our results suggest that the CF proximal airway defects originate during branching morphogenesis and that the lack of CFTR-dependent anion transport/liquid secretion likely contributes to these hypo-distended airways. PMID- 29467457 TI - Adenylosuccinate lyase enhances aggressiveness of endometrial cancer by increasing killer cell lectin-like receptor C3 expression by fumarate. AB - Adenylosuccinate lyase (ADSL) is an enzyme that plays important roles in de novo purine synthesis. Although ADSL was reported to be upregulated in various malignancies, such as colorectal, breast, and prostate cancer, as well as gliomas, the mechanism by which elevated ADSL expression contributes to cancer has not been elucidated. We previously performed a shotgun proteomics analysis to characterize specific proteins associated with the properties of the aldehyde dehydrogenase (ALDH)-high cell population, which was reported to be involved in tumorigenic potential, and showed that ADSL expression is upregulated in the ALDH high population of endometrial cancer. Here, we showed that ADSL is involved in endometrial cancer aggressiveness by regulating expression of killer cell lectin like receptor C3 (KLRC3), which is a receptor expressed on natural killer cells. Immunohistochemical analysis indicated that ADSL expression increased as endometrioid carcinoma specimens became more poorly differentiated and higher degree of primary tumor progression. Knockdown of ADSL in endometrial cancer cells decreased cell proliferation, migration, and invasive capability, and caused the cells to adopt a more rounded shape. DNA microarray analysis and quantitative real-time PCR showed that KLRC3 expression was decreased in ADSL knockdown cells. Knockdown of KLRC3 in endometrial cancer cells resulted in the same phenotype as knockdown of ADSL. Moreover, fumarate, which could be produced by ADSL and was recently shown to be an oncometabolite, recovered KLRC3 expression in ADSL knockdown cells, suggesting that fumarate produced by ADSL could regulate KLRC3 expression. Our findings indicate that ADSL enhances cell proliferation, migration, and invasive capability through regulation of KLRC3 expression by fumarate. PMID- 29467458 TI - Maresin 1 attenuates mitochondrial dysfunction through the ALX/cAMP/ROS pathway in the cecal ligation and puncture mouse model and sepsis patients. AB - Inflammation always accompanies infection during sepsis. Mitochondrial dysfunction and the role of reactive oxygen species (ROS) produced by mitochondria have been proposed in the pathogenesis of sepsis. Maresins have protective and resolving effects in experimental models of infection. In the present study, we investigated the effects of maresin 1 (MaR1) on mitochondrial function in cecal ligation and puncture (CLP)-induced sepsis and sepsis patients to identify mechanisms underlying maresin 1-mediated stimulation of ROS in mitochondria. We found that treatment with MaR1 significantly inhibited production of cytokines, decreased bacterial load in the peritoneal lavage fluid, reduced the number of neutrophils, decreased lactic acid level and upregulated cyclic AMP (cAMP) concentration, with the outcome of decreased lung injury in CLP induced sepsis in mice. The effects of MaR1 on downregulation nitric oxide (NOX) activity, improvement CAT and SOD activity to inhibit ROS production in mitochondria was dependent on lipoxin receptor (ALX) and cAMP. Survival rates were significantly increased after the treatment of mice with MaR1. In BMDM stimulated with LPS, MaR1 inhibited the ROS production, downregulated enzyme activity, reduced mtO2 production, increased mitochondrial membrane potential, improved adenosine triphosphate (ATP) content and mitochondrial DNA (mtDNA) copy number. Finally, the effects of MaR1 on ROS production in the blood of healthy volunteers stimulated with LPS or sepsis patients were associated with ALX and cAMP. Taken together, these data suggest that treatment with MaR1 could attenuate mitochondrial dysfunction during sepsis through regulating ROS production. PMID- 29467459 TI - Gate Modulation of the Spin-orbit Interaction in Bilayer Graphene Encapsulated by WS2 films. AB - Graphene has gigantic potential in the development of advanced spintronic devices. The interfacial interactions of graphene with semiconducting transition metal dichalcogenides improve the electronic properties drastically, making it an intriguing candidate for spintronic applications. Here, we fabricated bilayer graphene encapsulated by WS2 layers to exploit the interface-induced spin-orbit interaction (SOI). We designed a dual gated device, where the SOI is tuned by gate voltages. The strength of induced SOI in the bilayer graphene is dramatically elevated, which leads to a strong weak antilocalization (WAL) effect at low temperature. The quantitative analysis of WAL demonstrates that the spin relaxation time is 10 times smaller than in bilayer graphene on conventional substrates. To support these results, we also examined Shubnikov-de Haas (SdH) oscillations, which give unambiguous evidence of the zero-field spin-splitting in our bilayer graphene. The spin-orbit coupling constants estimated by two different measurements (i.e., the WAL effect and SdH oscillations) show close values as a function of gate voltage, supporting the self-consistency of this study's experimental results. The gate modulation of the SOI in bilayer graphene encapsulated by WS2 films establishes a novel way to explore the manipulation of spin-dependent transport through an electric field. PMID- 29467460 TI - Early antiretroviral therapy on reducing HIV transmission in China: strengths, weaknesses and next focus of the program. AB - Early antiretroviral therapy (ART) initiation is a recommended public health approach for the prevention of HIV-1 transmission. In this cohort study, we included 13132 serodiscordant couples. ART was initiated for patients with CD4+ T cell counts less than 200 cells/uL, 350 cells/uL, and 500 cells/uL respectively. This divided the ART treated couples into three groups. Univariate and multivariate intention-to-treat analyses were performed to examine the association between the study groups. Early-ART initiation was associated with a 45% lower risk of partner infection than was late-ART initiation (AHR 0.55, 95% CI, 0.37-0.81). Mid-ART initiation was associated with a 39% lower risk of partner infection than was late-ART initiation (AHR 0.61, 95% CI, 0.48-0.78). However, the risk reduction between the early and mid-ART groups was not significant. Drug compliance (AHR 1.55, 95% CI 1.03-2.35) and increased baseline viral load (AHR 1.41, 95% CI 1.33-1.51) were associated with an increased risk of infections among partners in the treatment. Prevention of HIV transmission as a result of early ART initiation was feasible on national and regional scales; however, many factors, such as the motivation to commence ART, adherence, and attrition, may affect the impact of this strategy in programmatic settings. PMID- 29467461 TI - The association of aspirin use with severity of acute exacerbation of chronic obstructive pulmonary disease: a retrospective cohort study. AB - Little is known about the effect of long-term aspirin use on acute severity of COPD. We hypothesized that, in patients hospitalized for acute exacerbation of COPD (AECOPD), long-term aspirin use is associated with lower risks of disease severity (in-hospital death, mechanical ventilation use, and hospital length-of stay). We conducted a retrospective cohort study using large population-based data from 2012 through 2013. Among 206,686 patients (aged >=40 years) hospitalized for AECOPD, aspirin users had lower in-hospital mortality (1.0 vs. 1.4%; OR 0.60 [95% CI 0.50-0.72]; P < 0.001) and lower risk of invasive mechanical ventilation use (1.7 vs. 2.6%; OR 0.64 [95% CI 0.55-0.73]; P < 0.001) compared to non-users, while there was no significant difference in risks of non invasive positive pressure ventilation use. Length-of-stay was shorter in aspirin users compared to non-users (P < 0.001). In sum, in patients with AECOPD, aspirin use was associated with lower rates of in-hospital mortality and invasive mechanical ventilation use, and shorter length-of-stay. PMID- 29467462 TI - hiPSC-derived neural stem cells from patients with schizophrenia induce an impaired angiogenesis. AB - Schizophrenia is a neurodevelopmental disease characterized by cerebral connectivity impairment and loss of gray matter. It was described in adult schizophrenia patients (SZP) that concentration of VEGFA, a master angiogenic factor, is decreased. Recent evidence suggests cerebral hypoperfusion related to a dysfunctional Blood Brain Barrier (BBB) in SZP. Since neurogenesis and blood vessel formation occur in a coincident and coordinated fashion, a defect in neurovascular development could result in increased vascular permeability and, therefore, in poor functionality of the SZP's neurons. Here, we characterized the conditioned media (CM) of human induced Pluripotent Stem Cells (hiPSC)-derived Neural Stem Cells of SZP (SZP NSC) versus healthy subjects (Ctrl NSC), and its impact on angiogenesis. Our results reveal that SZP NSC have an imbalance in the secretion and expression of several angiogenic factors, among them non-canonical neuro-angiogenic guidance factors. SZP NSC migrated less and their CM was less effective in inducing migration and angiogenesis both in vitro and in vivo. Since SZP originates during embryonic brain development, our findings suggest a defective crosstalk between NSC and endothelial cells (EC) during the formation of the neuro-angiogenic niche. PMID- 29467464 TI - Loss of the Drosophila m-AAA mitochondrial protease paraplegin results in mitochondrial dysfunction, shortened lifespan, and neuronal and muscular degeneration. AB - The progressive accumulation of dysfunctional mitochondria is implicated in aging and in common diseases of the elderly. To oppose this occurrence, organisms employ a variety of strategies, including the selective degradation of oxidatively damaged and misfolded mitochondrial proteins. Genetic studies in yeast indicate that the ATPase Associated with diverse cellular Activities (AAA+) family of mitochondrial proteases account for a substantial fraction of this protein degradation, but their metazoan counterparts have been little studied, despite the fact that mutations in the genes encoding these proteases cause a variety of human diseases. To begin to explore the biological roles of the metazoan mitochondrial AAA+ protease family, we have created a CRISPR/Cas9 allele of the Drosophila homolog of SPG7, which encodes an inner membrane-localized AAA+ protease known as paraplegin. Drosophila SPG7 mutants exhibited shortened lifespan, progressive locomotor defects, sensitivity to chemical and environmental stress, and muscular and neuronal degeneration. Ultrastructural examination of photoreceptor neurons indicated that the neurodegenerative phenotype of SPG7 mutants initiates at the synaptic terminal. A variety of mitochondrial defects accompanied the degenerative phenotypes of SPG7 mutants, including altered axonal transport of mitochondria, accumulation of electron dense material in the matrix of flight muscle mitochondria, reduced activities of respiratory chain complexes I and II, and severely swollen and dysmorphic mitochondria in the synaptic terminals of photoreceptors. Drosophila SPG7 mutants recapitulate key features of human diseases caused by mutations in SPG7, and thus provide a foundation for the identification of Drosophila paraplegin substrates and strategies that could be used to ameliorate the symptoms of these diseases. PMID- 29467463 TI - Bifunctional immune checkpoint-targeted antibody-ligand traps that simultaneously disable TGFbeta enhance the efficacy of cancer immunotherapy. AB - A majority of cancers fail to respond to immunotherapy with antibodies targeting immune checkpoints, such as cytotoxic T-lymphocyte antigen-4 (CTLA-4) or programmed death-1 (PD-1)/PD-1 ligand (PD-L1). Cancers frequently express transforming growth factor-beta (TGFbeta), which drives immune dysfunction in the tumor microenvironment by inducing regulatory T cells (Tregs) and inhibiting CD8+ and TH1 cells. To address this therapeutic challenge, we invent bifunctional antibody-ligand traps (Y-traps) comprising an antibody targeting CTLA-4 or PD-L1 fused to a TGFbeta receptor II ectodomain sequence that simultaneously disables autocrine/paracrine TGFbeta in the target cell microenvironment (a-CTLA4 TGFbetaRIIecd and a-PDL1-TGFbetaRIIecd). a-CTLA4-TGFbetaRIIecd is more effective in reducing tumor-infiltrating Tregs and inhibiting tumor progression compared with CTLA-4 antibody (Ipilimumab). Likewise, a-PDL1-TGFbetaRIIecd exhibits superior antitumor efficacy compared with PD-L1 antibodies (Atezolizumab or Avelumab). Our data demonstrate that Y-traps counteract TGFbeta-mediated differentiation of Tregs and immune tolerance, thereby providing a potentially more effective immunotherapeutic strategy against cancers that are resistant to current immune checkpoint inhibitors. PMID- 29467465 TI - Development and validation of a clinical prediction model for patient-reported pain and function after primary total knee replacement surgery. AB - To develop and validate a clinical prediction model of patient-reported pain and function after undergoing total knee replacement (TKR). We used data of 1,649 patients from the Knee Arthroplasty Trial who received primary TKR across 34 centres in the UK. The external validation included 595 patients from Southampton University Hospital, and Nuffield Orthopaedic Centre (Oxford). The outcome was the Oxford Knee Score (OKS) 12-month after TKR. Pre-operative predictors including patient characteristics and clinical factors were considered. Bootstrap backward linear regression analysis was used. Low pre-operative OKS, living in poor areas, high body mass index, and patient-reported anxiety or depression were associated with worse outcome. The clinical factors associated with worse outcome were worse pre-operative physical status, presence of other conditions affecting mobility and previous knee arthroscopy. Presence of fixed flexion deformity and an absent or damaged pre-operative anterior cruciate ligament (compared with intact) were associated with better outcome. Discrimination and calibration statistics were satisfactory. External validation predicted 21.1% of the variance of outcome. This is the first clinical prediction model for predicting self reported pain and function 12 months after TKR to be externally validated. It will help to inform to patients regarding expectations of the outcome after knee replacement surgery. PMID- 29467467 TI - Synaptic transmission: A hare as well as a tortoise. PMID- 29467466 TI - Distinguishing Human Peripheral Blood NK Cells from CD56dimCD16dimCD69+CD103+ Resident Nasal Mucosal Lavage Fluid Cells. AB - Natural killer (NK) cells are members of the innate lymphoid cells group 1 (ILC1s), which play a critical role in innate host defense against viruses and malignancies. While many studies have examined the role of circulating peripheral blood (PB) CD56+ NK cells, little is known about the resident CD56+ cell population. Therefore, matched CD56+ cells from nasal lavage fluid (NLF) and PB of smokers and non-smokers were compared phenotypically, via flow cytometry, and functionally, via NK-cell specific gene expression. NLF and PB CD56+ cells had similar expression of CD56, but differentially expressed tissue residency (CD69 and CD103) and cytotoxicity (CD16) markers. In addition, NLF CD56dim cells expressed lower levels of cytotoxicity-associated genes, perforin (PRF1) and granzyme B (GZMB), and increased levels of cytokines and cell signaling molecules, TRAIL, IFNGR2, and IL8, as compared to PB CD56dim cells. In smokers, ITGA2 was downregulated in NLF CD56dim cells, while markers of cytotoxic function were primarily downregulated in PB CD56dim NK cells. Overall, NLF CD56dim cells are a unique cell population that likely play a role in orchestrating innate immune responses in the nasal cavity, which is distinct from their role as a non antigen-restricted cytotoxic CD56dim lymphocytes in the PB.

AB - The CNS regulates body weight; however, we still lack a clear understanding of what drives decisions about when, how much and what to eat. A vast array of peripheral signals provides information to the CNS regarding fluctuations in energy status. The CNS then integrates this information to influence acute feeding behaviour and long-term energy homeostasis. Previous paradigms have delegated the control of long-term energy homeostasis to the hypothalamus and short-term changes in feeding behaviour to the hindbrain. However, recent studies have identified target hindbrain neurocircuitry that integrates the orchestration of individual bouts of ingestion with the long-term regulation of energy balance.

AB - Per occasion, alcohol consumption is higher in adolescents than in adults in both humans and laboratory animals, with changes in the adolescent brain probably contributing to this elevated drinking. This Review examines the contributors to and consequences of the use of alcohol in adolescents. Human adolescents with a history of alcohol use differ neurally and cognitively from other adolescents; some of these differences predate the commencement of alcohol consumption and serve as potential risk factors for later alcohol use, whereas others emerge from its use. The consequences of alcohol use in human adolescents include alterations in attention, verbal learning, visuospatial processing and memory, along with altered development of grey and white matter volumes and disrupted white matter integrity. The functional consequences of adolescent alcohol use emerging from studies of rodent models of adolescence include decreased cognitive flexibility, behavioural inefficiencies and elevations in anxiety, disinhibition, impulsivity and risk-taking. Rodent studies have also showed that adolescent alcohol use can impair neurogenesis, induce neuroinflammation and epigenetic alterations, and lead to the persistence of adolescent-like neurobehavioural phenotypes into adulthood. Although only a limited number of studies have examined comparable measures in humans and laboratory animals, the available data provide evidence for notable across-species similarities in the neural consequences of adolescent alcohol exposure, providing support for further translational efforts in this context. PMID- 29467471 TI - Network analysis of coronary artery disease risk genes elucidates disease mechanisms and druggable targets. AB - Genome-wide association studies (GWAS) have identified over two hundred chromosomal loci that modulate risk of coronary artery disease (CAD). The genes affected by variants at these loci are largely unknown and an untapped resource to improve our understanding of CAD pathophysiology and identify potential therapeutic targets. Here, we prioritized 68 genes as the most likely causal genes at genome-wide significant loci identified by GWAS of CAD and examined their regulatory roles in 286 metabolic and vascular tissue gene-protein sub networks ("modules"). The modules and genes within were scored for CAD druggability potential. The scoring enriched for targets of cardiometabolic drugs currently in clinical use and in-depth analysis of the top-scoring modules validated established and revealed novel target tissues, biological processes, and druggable targets. This study provides an unprecedented resource of tissue defined gene-protein interactions directly affected by genetic variance in CAD risk loci. PMID- 29467472 TI - Effector CD4+ T cells recognize intravascular antigen presented by patrolling monocytes. AB - Although effector CD4+ T cells readily respond to antigen outside the vasculature, how they respond to intravascular antigens is unknown. Here we show the process of intravascular antigen recognition using intravital multiphoton microscopy of glomeruli. CD4+ T cells undergo intravascular migration within uninflamed glomeruli. Similarly, while MHCII is not expressed by intrinsic glomerular cells, intravascular MHCII-expressing immune cells patrol glomerular capillaries, interacting with CD4+ T cells. Following intravascular deposition of antigen in glomeruli, effector CD4+ T-cell responses, including NFAT1 nuclear translocation and decreased migration, are consistent with antigen recognition. Of the MHCII+ immune cells adherent in glomerular capillaries, only monocytes are retained for prolonged durations. These cells can also induce T-cell proliferation in vitro. Moreover, monocyte depletion reduces CD4+ T-cell dependent glomerular inflammation. These findings indicate that MHCII+ monocytes patrolling the glomerular microvasculature can present intravascular antigen to CD4+ T cells within glomerular capillaries, leading to antigen-dependent inflammation. PMID- 29467473 TI - Embryonic lethality in mice lacking Trim59 due to impaired gastrulation development. AB - TRIM family members have been implicated in a variety of biological processes such as differentiation and development. We here found that Trim59 plays a critical role in early embryo development from blastocyst stage to gastrula. There existed delayed development and empty yolk sacs from embryonic day (E) 8.5 in Trim59-/- embryos. No viable Trim59-/- embryos were observed beyond E9.5. Trim59 deficiency affected primary germ layer formation at the beginning of gastrulation. At E6.5 and E7.5, the expression of primary germ layer formation associated genes including Brachyury, lefty2, Cer1, Otx2, Wnt3, and BMP4 was reduced in Trim59-/- embryos. Homozygous mutant embryonic epiblasts were contracted and the mesoderm was absent. Trim59 could interact with actin- and myosin-associated proteins. Its deficiency disturbed F-actin polymerization during inner cell mass differentiation. Trim59-mediated polymerization of F-actin was via WASH K63-linked ubiquitination. Thus, Trim59 may be a critical regulator for early embryo development from blastocyst stage to gastrula through modulating F-actin assembly.

AB - Infective endocarditis (IE) is associated with high morbidity and mortality rates. The predominant bacteria causing IE is Staphylococcus aureus (S. aureus), which can bind to existing thrombi on heart valves and generate vegetations (biofilms). In this in vitro flow study, we evaluated sonobactericide as a novel strategy to treat IE, using ultrasound and an ultrasound contrast agent with or without other therapeutics. We developed a model of IE biofilm using human whole blood clots infected with patient-derived S. aureus (infected clots). Histology and live-cell imaging revealed a biofilm layer of fibrin-embedded living Staphylococci around a dense erythrocyte core. Infected clots were treated under flow for 30 minutes and degradation was assessed by time-lapse microscopy imaging. Treatments consisted of either continuous plasma flow alone or with different combinations of therapeutics: oxacillin (antibiotic), recombinant tissue plasminogen activator (rt-PA; thrombolytic), intermittent continuous-wave low-frequency ultrasound (120-kHz, 0.44 MPa peak-to-peak pressure), and an ultrasound contrast agent (Definity). Infected clots exposed to the combination of oxacillin, rt-PA, ultrasound, and Definity achieved 99.3 +/- 1.7% loss, which was greater than the other treatment arms. Effluent size measurements suggested low likelihood of emboli formation. These results support the continued investigation of sonobactericide as a therapeutic strategy for IE. PMID- 29467476 TI - A Simple 3-Parameter Model for Cancer Incidences. AB - We propose a simple 3-parameter model that provides very good fits for incidence curves of 18 common solid cancers even when variations due to different locations, races, or periods are taken into account. From a data perspective, we use model selection (Akaike information criterion) to show that this model, which is based on the Weibull distribution, outperforms other simple models like the Gamma distribution. From a modeling perspective, the Weibull distribution can be justified as modeling the accumulation of driver events, which establishes a link to stem cell division based cancer development models and a connection to a recursion formula for intrinsic cancer risk published by Wu et al. For the recursion formula a closed form solution is given, which will help to simplify future analyses. Additionally, we perform a sensitivity analysis for the parameters, showing that two of the three parameters can vary over several orders of magnitude. However, the shape parameter of the Weibull distribution, which corresponds to the number of driver mutations required for cancer onset, can be robustly estimated from epidemiological data. PMID- 29467477 TI - Microsecond dark-exciton valley polarization memory in two-dimensional heterostructures. AB - Transition metal dichalcogenides have valley degree of freedom, which features optical selection rule and spin-valley locking, making them promising for valleytronics devices and quantum computation. For either application, a long valley polarization lifetime is crucial. Previous results showed that it is around picosecond in monolayer excitons, nanosecond for local excitons and tens of nanosecond for interlayer excitons. Here we show that the dark excitons in two dimensional heterostructures provide a microsecond valley polarization memory thanks to the magnetic field induced suppression of valley mixing. The lifetime of the dark excitons shows magnetic field and temperature dependence. The long lifetime and valley polarization lifetime of the dark exciton in two-dimensional heterostructures make them promising for long-distance exciton transport and macroscopic quantum state generations. PMID- 29467479 TI - Flat epithelial atypia in directional vacuum-assisted biopsy of breast microcalcifications: surgical excision may not be necessary. AB - The aim of this study was to analyze the clinicopathological features of patients with flat epithelial atypia, diagnosed in directional vacuum-assisted biopsy targeting microcalcifications, to identify upgrade rate to in situ ductal or invasive breast carcinoma, and determine factors predicting carcinoma in the subsequent excision. We retrospectively evaluated the histological, clinical, and mammographic features of 69 cases from 65 women, with directional vacuum-assisted biopsy-diagnosed flat epithelial atypia with or without atypical ductal hyperplasia or atypical lobular hyperplasia, which underwent subsequent surgical excision. The extent and percentage of microcalcifications sampled by directional vacuum-assisted biopsy were evaluated by mammography. All biopsy and surgical excision slides were reviewed. The age of the women ranged from 40 to 85 years (mean 57 years). All patients presented with mammographically detected microcalcifications only, except in one case that had associated architectural distortion. Extent of calcifications ranged from <1 cm (n = 47), 1-3 cm (n = 15) to > 3 cm (n = 6), and no measurement (n = 1). A mean of 11 cores (range 6-25) was obtained from each lesion. Post-biopsy mammogram revealed >90% removal of calcifications in 81% of cases. Pure flat epithelial atypia represented nearly two-thirds of directional vacuum-assisted biopsy specimens (n = 43, 62%), while flat epithelial atypia coexisted with atypical ductal hyperplasia (18 cases, 26%), or atypical lobular hyperplasia (8 cases, 12%). Upon excision, none of the cases were upgraded to in situ ductal or invasive breast cancer. In one case, however, an incidental, tubular carcinoma (4 mm) was found away from biopsy site. Excluding this case, the upgrade rate was 0%. Our study adds to the growing evidence that diagnosis of flat epithelial atypia on directional vacuum-assisted biopsy for microcalcifications as the only imaging finding is not associated with a significant upgrade to carcinoma on excision, and therefore, excision may not be necessary. Additionally, excision may not be necessary for flat epithelial atypia with atypical ductal hyperplasia limited to <=2 terminal duct-lobular units, if at least 90% of calcifications have been removed on biopsy. PMID- 29467478 TI - Reappraisal of HER2 status in the spectrum of advanced urothelial carcinoma: a need of guidelines for treatment eligibility. AB - Although human epidermal growth factor receptor 2 (HER2) may represent a therapeutic target, its evaluation in urothelial carcinoma of the bladder does not rely on a standardized scoring system by immunohistochemistry or fluorescent in situ hybridization (FISH), as reflected by various methodology in the literature and clinical trials. Our aim was to improve and standardize HER2 amplification detection in bladder cancer. We assessed immunohistochemical criteria derived from 2013 American Society of Clinical Oncology (ASCO)/College of American Pathologists (CAPs) guidelines for breast cancer and investigated intratumoral heterogeneity in a retrospective multicentric cohort of 188 patients with locally advanced urothelial carcinoma of the bladder. Immunohistochemistry was performed on 178 primary tumors and 126 lymph node metastases, eligible cases (moderate/strong, complete/incomplete membrane staining) were assessed by FISH. HER2 overexpression was more frequent with 2013 ASCO/CAP than 2007 ASCO/CAP guidelines (p < 0.0001). The rate of positive HER2 FISH was similar between primary tumor and lymph node metastases (8%). Among positive FISH cases, 48% were associated with moderate/strong incomplete membrane staining that were not scored eligible for FISH by 2007 ASCO/CAP criteria. Among 3+ immunohistochemistry score cases, 67% were associated with HER2-positive FISH. Concordance between primary tumors and matched lymph node metastases was moderate for immunohistochemistry (kappa = 0.54 (CI 95%, 0.41-0.67)) and FISH (kappa = 0.50 (CI 95%, 0.20-0.79)). HER2-positive FISH was more frequent in micropapillary carcinomas (12%) and carcinoma with squamous differentiation (11%) than in pure conventional carcinoma (6%). Intratumoral heterogeneity for HER2 immunohistochemistry was observed in 7% primary tumor and 6% lymph node metastases; 24% positive HER2 FISH presented intratumoral heterogeneity. Our study suggests that HER2 evaluation should include an immunohistochemistry screening step with eligibility for FISH including incomplete/complete and moderate/strong membrane staining. Spatial or temporal intratumoral heterogeneity prompts to perform evaluation on both tumor and lymph node, and for each histological variant observed. PMID- 29467480 TI - Adenoid cystic carcinomas of the salivary gland, lacrimal gland, and breast are morphologically and genetically similar but have distinct microRNA expression profiles. AB - Adenoid cystic carcinoma is among the most frequent malignancies in the salivary and lacrimal glands and has a grave prognosis characterized by frequent local recurrences, distant metastases, and tumor-related mortality. Conversely, adenoid cystic carcinoma of the breast is a rare type of triple-negative (estrogen and progesterone receptor, HER2) and basal-like carcinoma, which in contrast to other triple-negative and basal-like breast carcinomas has a very favorable prognosis. Irrespective of site, adenoid cystic carcinoma is characterized by gene fusions involving MYB, MYBL1, and NFIB, and the reason for the different clinical outcomes is unknown. In order to identify the molecular mechanisms underlying the discrepancy in clinical outcome, we characterized the phenotypic profiles, pattern of gene rearrangements, and global microRNA expression profiles of 64 salivary gland, 9 lacrimal gland, and 11 breast adenoid cystic carcinomas. All breast and lacrimal gland adenoid cystic carcinomas had triple-negative and basal like phenotypes, while salivary gland tumors were indeterminate in 13% of cases. Aberrations in MYB and/or NFIB were found in the majority of cases in all three locations, whereas MYBL1 involvement was restricted to tumors in the salivary gland. Global microRNA expression profiling separated salivary and lacrimal gland adenoid cystic carcinoma from their respective normal glands but could not distinguish normal breast adenoid cystic carcinoma from normal breast tissue. Hierarchical clustering separated adenoid cystic carcinomas of salivary gland origin from those of the breast and placed lacrimal gland carcinomas in between these. Functional annotation of the microRNAs differentially expressed between salivary gland and breast adenoid cystic carcinoma showed these as regulating genes involved in metabolism, signal transduction, and genes involved in other cancers. In conclusion, microRNA dysregulation is the first class of molecules separating adenoid cystic carcinoma according to the site of origin. This highlights a novel venue for exploring the biology of adenoid cystic carcinoma. PMID- 29467481 TI - The mechanistic causes of peripheral intravenous catheter failure based on a parametric computational study. AB - Peripheral intravenous catheters (PIVCs) are the most commonly used invasive medical device, yet up to 50% fail. Many pathways to failure are mechanistic and related to fluid mechanics, thus can be investigated using computational fluid dynamics (CFD). Here we used CFD to investigate typical PIVC parameters (infusion rate, catheter size, insertion angle and tip position) and report the hemodynamic environment (wall shear stress (WSS), blood damage, particle residence time and venous stasis volumes) within the vein and catheter, and show the effect of each PIVC parameter on each hemodynamic measure. Catheter infusion rate has the greatest impact on our measures, with catheter orientation also playing a significant role. In some PIVC configurations WSS was 3254 times higher than the patent vein, and blood damage was 512 times greater, when compared to control conditions. Residence time is geometry-dependent and decreases exponentially with increasing insertion angle. Stasis volume decreased with increasing infusion rate and, to a lesser degree, insertion angle. Even without infusion, the presence of the catheter changes the flow field, causing low velocity recirculation at the catheter tip. This research demonstrates how several controllable factors impact important mechanisms of PIVC failure. These data, the first of their kind, suggest limiting excessive infusion rates in PIVC. PMID- 29467482 TI - Synthetic dimensions in ultracold polar molecules. AB - Synthetic dimensions alter one of the most fundamental properties in nature, the dimension of space. They allow, for example, a real three-dimensional system to act as effectively four-dimensional. Driven by such possibilities, synthetic dimensions have been engineered in ongoing experiments with ultracold matter. We show that rotational states of ultracold molecules can be used as synthetic dimensions extending to many - potentially hundreds of - synthetic lattice sites. Microwaves coupling rotational states drive fully controllable synthetic inter site tunnelings, enabling, for example, topological band structures. Interactions leads to even richer behavior: when molecules are frozen in a real space lattice with uniform synthetic tunnelings, dipole interactions cause the molecules to aggregate to a narrow strip in the synthetic direction beyond a critical interaction strength, resulting in a quantum string or a membrane, with an emergent condensate that lives on this string or membrane. All these phases can be detected using local measurements of rotational state populations. PMID- 29467483 TI - Clove Bud Oil Modulates Pathogenicity Phenotypes of the Opportunistic Human Pathogen Pseudomonas aeruginosa. AB - Earlier studies from our laboratory have demonstrated that clove bud oil (CBO) attenuates expression of certain virulence factors of Pseudomonas aeruginosa PAO1. Here, we probe more deeply into the effect of CBO on four pseudomonal proteases - elastase A, elastase B, protease IV and alkaline protease - each known to play key roles in disease pathogenesis. CBO inhibited the activity of these proteases present in the bacterial culture supernatant. Zymography studies indicated that these proteases can activate host matrix metalloproteases (MMPs) to establish infection, through conversion of pro-MMP-2 to active MMP-2. PAO1 is a predominant pathogen in burn wound infections and we show the modulatory effect of CBO on MMPs in an in vitro model of burn injury. Furthermore, CBO induced dose dependent neutrophil extracellular trap formation in human neutrophils. CBO also increased the survival of C. elegans infected with PAO1, establishing an anti infective role in a whole animal model of pathogenesis. LC-MS/MS analysis indicated that CBO treatment elicited a significant reduction of signalling molecules (Acyl-Homoserine-Lactone) involved in quorum sensing regulation. Our observations demonstrate that CBO attenuates key virulence mechanisms of this important human pathogen, while concomitantly enhancing host innate immunomodulatory functions, with potential implications for topical therapy against antibiotic-resistant infections. PMID- 29467484 TI - We skip to work: alternative splicing in normal and malignant myelopoiesis. AB - Alternative splicing expands the transcriptome thereby promoting protein diversity. It governs critical cellular processes such as differentiation, proliferation and apoptosis in a tissue-specific manner. Aberrant splicing consequent to mutations in splicing factors and disruption of isoform ratios in key regulatory genes provides an important contribution to the pathogenesis of the myelodysplastic syndromes and myeloid leukemia. We review here the central role of alternative splicing in regulating myelopoiesis, and provide clear examples of how global splicing disruption or specific aberrant splicing events might promote leukemogenesis. We discuss the growing number of mechanistic links between epigenetic factors and alternative splicing. Finally, we address the potential utility of alternatively spliced isoforms as biomarkers and the development of novel therapies that modulate alternative splicing in myeloid and other malignancies. PMID- 29467485 TI - The cell fate determinant Scribble is required for maintenance of hematopoietic stem cell function. AB - Cell fate determinants influence self-renewal potential of hematopoietic stem cells. Scribble and Llgl1 belong to the Scribble polarity complex and reveal tumor-suppressor function in drosophila. In hematopoietic cells, genetic inactivation of Llgl1 leads to expansion of the stem cell pool and increases self renewal capacity without conferring malignant transformation. Here we show that genetic inactivation of its putative complex partner Scribble results in functional impairment of hematopoietic stem cells (HSC) over serial transplantation and during stress. Although loss of Scribble deregulates transcriptional downstream effectors involved in stem cell proliferation, cell signaling, and cell motility, these effectors do not overlap with transcriptional targets of Llgl1. Binding partner analysis of Scribble in hematopoietic cells using affinity purification followed by mass spectometry confirms its role in cell signaling and motility but not for binding to polarity modules described in drosophila. Finally, requirement of Scribble for self-renewal capacity also affects leukemia stem cell function. Thus, Scribble is a regulator of adult HSCs, essential for maintenance of HSCs during phases of cell stress. PMID- 29467486 TI - ERIC recommendations for TP53 mutation analysis in chronic lymphocytic leukemia update on methodological approaches and results interpretation. AB - In chronic lymphocytic leukemia (CLL), TP53 gene defects, due to deletion of the 17p13 locus and/or mutation(s) within the TP53 gene, are associated with resistance to chemoimmunotherapy and a particularly dismal clinical outcome. On these grounds, analysis of TP53 aberrations has been incorporated into routine clinical diagnostics to improve patient stratification and optimize therapeutic decisions. The predictive implications of TP53 aberrations have increasing significance in the era of novel targeted therapies, i.e., inhibitors of B-cell receptor (BcR) signaling and anti-apoptotic BCL2 family members, owing to their efficacy in patients with TP53 defects. In this report, the TP53 Network of the European Research Initiative on Chronic Lymphocytic Leukemia (ERIC) presents updated recommendations on the methodological approaches for TP53 mutation analysis. Moreover, it provides guidance to ensure that the analysis is performed in a timely manner for all patients requiring treatment and that the data is interpreted and reported in a consistent, standardized, and accurate way. Since next-generation sequencing technologies are gaining prominence within diagnostic laboratories, this report also offers advice and recommendations for the interpretation of TP53 mutation data generated by this methodology. PMID- 29467487 TI - Loss of heterozygosity as a marker of homologous repair deficiency in multiple myeloma: a role for PARP inhibition? AB - PARP inhibitors can induce synthetic lethality in tumors characterized by homologous recombination deficiency (HRD), which can be detected by evaluating genome-wide loss of heterozygosity (LOH). Multiple myeloma (MM) is a genetically unstable tumor and we hypothesized that HRD-related LOH (HRD-LOH) could be detected in patient samples, supporting a potential role for PARP inhibition in MM. Using results from targeted next-generation sequencing studies (FoundationOne(r) Heme), we analyzed HRD-LOH in patients at all disease stages (MGUS (n = 7), smoldering MM (SMM, n = 30), newly diagnosed MM (NDMM, n = 71), treated MM (TRMM, n = 64), and relapsed MM (RLMM, n = 234)) using an algorithm to identify HRD-LOH segments. We demonstrated HRD-LOH in MM samples, increasing as disease progresses. The extent of genomic HRD-LOH correlated with high-risk disease markers. Outcome of RLMM patients, the biggest clinical group, was analyzed and patients with HRD-LOH above the third quartile (>=5% HRD-LOH) had significantly worse progression-free and overall survival than those with lower levels (p < 0.001). Mutations in key homologous recombination genes account for some, but not all, of the cases with an excess of HRD-LOH. These data support the further evaluation of PARP inhibitors in MM patients, particularly in the relapsed setting with a high unmet need for new treatments. PMID- 29467488 TI - ANP32A regulates histone H3 acetylation and promotes leukemogenesis. AB - Deregulation of key regulators of histone modification is important in the initiation and progression of human leukemia. Acidic leucine-rich nuclear phosphoprotein-32A (ANP32A) participates in histone acetylation and its role in acute myeloid leukemia remains unclear. Here we observed significant upregulation of ANP32A in primary AML cells, which was essential for AML cell proliferation, survival, and colony formation. Integrative analysis of the genome-wide histone H3 acetylation and gene expression demonstrated that ANP32A deficiency reduced histone H3 acetylation, in accordance with changes in gene expression. Notably, significant histone H3 acetylation enrichment was associated with mRNA changes in lipid-related genes, including APOC1, PCSK9, P2RX1, and LPPR3. Indeed, over expression of APOC1 partially compensated the proliferation-defect phenotype in ANP32A deficient AML cells while APOC1 knockdown alone mimicked the effect of ANP32A deficiency. Collectively, our data indicate that ANP32A is a novel regulator of histone H3 acetylation and promotes leukemogenesis. PMID- 29467489 TI - A human bone marrow mesodermal-derived cell population with hemogenic potential. AB - The presence, within the human bone marrow, of cells with both endothelial and hemogenic potential has been controversial. Herein, we identify, within the human fetal bone marrow, prior to establishment of hematopoiesis, a unique APLNR+, Stro 1+ cell population, co-expressing markers of early mesodermal precursors and/or hemogenic endothelium. In adult marrow, cells expressing similar markers are also found, but at very low frequency. These adult-derived cells can be extensively culture expanded in vitro without loss of potential, they preserve a biased hemogenic transcriptional profile, and, upon in vitro induction with OCT4, assume a hematopoietic phenotype. In vivo, these cells, upon transplantation into a fetal microenvironment, contribute to the vasculature, and generate hematopoietic cells that provide multilineage repopulation upon serial transplantation. The identification of this human somatic cell population provides novel insights into human ontogenetic hematovascular potential, which could lead to a better understanding of, and new target therapies for, malignant and nonmalignant hematologic disorders. PMID- 29467490 TI - Targeting MYC in multiple myeloma. AB - Multiple myeloma (MM) is a plasma cell tumor marked by clonal evolution and preceded by a premalignant stage, which progresses via molecular pathway deregulation, including MYC activation. This activation relates to translocation or gain of the MYC locus and deregulation of upstream pathways such as IRF4, DIS3/LIN28B/let-7, or MAPK. Precision medicine is an approach to predict more accurately which treatment strategies for a particular disease will work in which groups of patients, in contrast to a "one-size-fits-all" approach. The knowledge of mechanisms responsible for MYC deregulation in MM enables identification of vulnerabilities and therapeutic targets in MYC-driven tumors. MYC can be targeted directly or indirectly, by interacting with several of its functions in cancer. Several such therapeutic strategies are evaluated in clinical trials in MM. In this review, we describe the mechanism of MYC activation in MM, the role of MYC in cancer progression, and the therapeutic options to targeting MYC. PMID- 29467491 TI - MYC-containing amplicons in acute myeloid leukemia: genomic structures, evolution, and transcriptional consequences. AB - Double minutes (dmin), homogeneously staining regions, and ring chromosomes are vehicles of gene amplification in cancer. The underlying mechanism leading to their formation as well as their structure and function in acute myeloid leukemia (AML) remain mysterious. We combined a range of high-resolution genomic methods to investigate the architecture and expression pattern of amplicons involving chromosome band 8q24 in 23 cases of AML (AML-amp). This revealed that different MYC-dmin architectures can coexist within the same leukemic cell population, indicating a step-wise evolution rather than a single event origin, such as through chromothripsis. This was supported also by the analysis of the chromothripsis criteria, that poorly matched the model in our samples. Furthermore, we found that dmin could evolve toward ring chromosomes stabilized by neocentromeres. Surprisingly, amplified genes (mainly PVT1) frequently participated in fusion transcripts lacking a corresponding DNA template. We also detected a significant overexpression of the circular RNA of PVT1 (circPVT1) in AML-amp cases versus AML with a normal karyotype. Our results show that 8q24 amplicons in AML are surprisingly plastic DNA structures with an unexpected association to novel fusion transcripts and circular RNAs. PMID- 29467492 TI - The HDAC inhibitor SAHA regulates CBX2 stability via a SUMO-triggered ubiquitin mediated pathway in leukemia. AB - Polycomb group (PcG) proteins regulate transcription, playing a key role in stemness and differentiation. Deregulation of PcG members is known to be involved in cancer pathogenesis. Emerging evidence suggests that CBX2, a member of the PcG protein family, is overexpressed in several human tumors, correlating with lower overall survival. Unraveling the mechanisms regulating CBX2 expression may thus provide a promising new target for anticancer strategies. Here we show that the HDAC inhibitor SAHA regulates CBX2 stability via a SUMO-triggered ubiquitin mediated pathway in leukemia. We identify CBX4 and RNF4 as the E3 SUMO and E3 ubiquitin ligase, respectively, and describe the specific molecular mechanism regulating CBX2 protein stability. Finally, we show that CBX2-depleted leukemic cells display impaired proliferation, underscoring its critical role in regulating leukemia cell tumorogenicity. Our results show that SAHA affects CBX2 stability, revealing a potential SAHA-mediated anti-leukemic activity though SUMO2/3 pathway. PMID- 29467493 TI - c-Jun/AP-1 overexpression reprograms ERalpha signaling related to tamoxifen response in ERalpha-positive breast cancer. AB - A critical mechanism that has been proposed for transcription regulation by estrogen receptor alpha (ER) is the tethering of ER to DNA via other transcription factors, such as AP-1. However, genome-wide assessment of the overlap in chromatin binding repertoires of these two transcription factors has not been reported. Here, we show that the AP-1 transcription factor c-Jun interacts with ER and that c-Jun chromatin binding shows extensive overlap with ER binding at the global level. Further, we show that c-Jun overexpression reprograms ER chromatin binding and modulates ER-mediated gene regulation. Our data are consistent with a mechanism where estrogen/ER-dependent crosstalk with AP-1 at the transcriptional level is mediated through the tethering of ER to DNA bound AP-1. Additionally, in our system c-Jun overexpression causes reduced sensitivity to tamoxifen in ER+ breast cancer cells. Integrated cistrome, transcriptome, and clinical data reveal TGFBI as a candidate gene which may confer tamoxifen resistance by ER and AP-1 crosstalk. Further, we show that TGFBI expression is elevated in breast cancer compared to normal breast. Together, our data provide a novel genome-wide footprint of ER and AP-1 crosstalk and suggest AP-1 and TGFBI signaling as potential therapeutic targets in AP-1-overexpressing ER-positive breast tumors.

AB - Thrombospondin-2 (TSP2) is an anti-angiogenic matricellular protein that inhibits tumor growth and angiogenesis. Tumor-associated blood vascular endothelial cells (BECs) were isolated from human invasive bladder cancers and from matched normal bladder tissue by immuno-laser capture microdissection. Exon expression profiling analyses revealed a particularly high expression of a short TSP2 transcript containing only the last 9 (3') exons of the full-length TSP2 transcript. Using 5' and 3' RACE (rapid amplification of cDNA ends) and Sanger sequencing, we confirmed the existence of the shorter transcript of TSP2 (sTSP2) and determined its sequence which completely lacked the anti-angiogenic thrombospondin type 1 repeats domain. The largest open reading frame predicted within the transcript comprises 209 amino acids and matches almost completely the C-terminal lectin domain of full-length TSP2. We produced recombinant sTSP2 and found that unlike the full-length TSP2, sTSP2 did not inhibit vascular endothelial growth factor-A induced proliferation of cultured human BECs, but in contrast when combined with TSP2 blocked the inhibitory effects of TSP2 on BEC proliferation. In vivo studies with stably transfected A431 squamous cell carcinoma cells revealed that full length TSP2, but not sTSP2, inhibited tumor growth and angiogenesis. This study reveals that the transcriptional program of tumor stromal cells can change to transcribe a new version of an endogenous angiogenesis inhibitor that has lost its anti-angiogenic activity. PMID- 29467495 TI - Representations of naturalistic stimulus complexity in early and associative visual and auditory cortices. AB - The complexity of sensory stimuli has an important role in perception and cognition. However, its neural representation is not well understood. Here, we characterize the representations of naturalistic visual and auditory stimulus complexity in early and associative visual and auditory cortices. This is realized by means of encoding and decoding analyses of two fMRI datasets in the visual and auditory modalities. Our results implicate most early and some associative sensory areas in representing the complexity of naturalistic sensory stimuli. For example, parahippocampal place area, which was previously shown to represent scene features, is shown to also represent scene complexity. Similarly, posterior regions of superior temporal gyrus and superior temporal sulcus, which were previously shown to represent syntactic (language) complexity, are shown to also represent music (auditory) complexity. Furthermore, our results suggest the existence of gradients in sensitivity to naturalistic sensory stimulus complexity in these areas. PMID- 29467496 TI - Trends in seasonal warm anomalies across the contiguous United States: Contributions from natural climate variability. AB - Many studies have shown the importance of anthropogenic greenhouse gas emissions in contributing to observed upward trends in the occurrences of temperature extremes over the U.S. However, few studies have investigated the contributions of internal variability in the climate system to these observed trends. Here we use daily maximum temperature time series from the North American Land Data Assimilation System Phase 2 (NLDAS-2) dataset to identify trends in seasonal warm anomalies over the contiguous U.S. in the three most recent decades and explore their relationships to low-frequency modes of internal climate variability. The results reveal substantial upward trends in the frequency of warm anomalies in all seasons and in all regions of the U.S., except for portions of the Intermountain West in winter where significant downward trends occur. The strengths and regional coverage of the trends, however, differ considerably by season. These trends can be explained, in part, by the large-scale anomalous atmospheric circulations associated with low-frequency sea-surface temperature oscillations characterized by the Pacific Decadal Oscillation (PDO) and the Atlantic Multidecadal Oscillation (AMO). The association between the upward trends in the seasonal warm anomalies and PDO and AMO is further confirmed by the century-long (1871-2012) Twentieth Century Reanalysis dataset. PMID- 29467497 TI - Altered TAOK2 activity causes autism-related neurodevelopmental and cognitive abnormalities through RhoA signaling. AB - Atypical brain connectivity is a major contributor to the pathophysiology of neurodevelopmental disorders (NDDs) including autism spectrum disorders (ASDs). TAOK2 is one of several genes in the 16p11.2 microdeletion region, but whether it contributes to NDDs is unknown. We performed behavioral analysis on Taok2 heterozygous (Het) and knockout (KO) mice and found gene dosage-dependent impairments in cognition, anxiety, and social interaction. Taok2 Het and KO mice also have dosage-dependent abnormalities in brain size and neural connectivity in multiple regions, deficits in cortical layering, dendrite and synapse formation, and reduced excitatory neurotransmission. Whole-genome and -exome sequencing of ASD families identified three de novo mutations in TAOK2 and functional analysis in mice and human cells revealed that all the mutations impair protein stability, but they differentially impact kinase activity, dendrite growth, and spine/synapse development. Mechanistically, loss of Taok2 activity causes a reduction in RhoA activation, and pharmacological enhancement of RhoA activity rescues synaptic phenotypes. Together, these data provide evidence that TAOK2 is a neurodevelopmental disorder risk gene and identify RhoA signaling as a mediator of TAOK2-dependent synaptic development. PMID- 29467498 TI - Early Detection of Preeclampsia Using Circulating Small non-coding RNA. AB - Preeclampsia is one of the most dangerous pregnancy complications, and the leading cause of maternal and perinatal mortality and morbidity. Although the clinical symptoms appear late, its origin is early, and hence detection is feasible already at the first trimester. In the current study, we investigated the abundance of circulating small non-coding RNAs in the plasma of pregnant women in their first trimester, seeking transcripts that best separate the preeclampsia samples from those of healthy pregnant women. To this end, we performed small non-coding RNAs sequencing of 75 preeclampsia and control samples, and identified 25 transcripts that were differentially expressed between preeclampsia and the control groups. Furthermore, we utilized those transcripts and created a pipeline for a supervised classification of preeclampsia. Our pipeline generates a logistic regression model using a 5-fold cross validation on numerous random partitions into training and blind test sets. Using this classification procedure, we achieved an average AUC value of 0.86. These findings suggest the predictive value of circulating small non-coding RNA in the first trimester, warranting further examination, and lay the foundation for producing a novel early non-invasive diagnostic tool for preeclampsia, which could reduce the life-threatening risk for both the mother and fetus. PMID- 29467499 TI - Coupling a single solid-state quantum emitter to an array of resonant plasmonic antennas. AB - Plasmon resonant arrays or meta-surfaces shape both the incoming optical field and the local density of states for emission processes. They provide large regions of enhanced emission from emitters and greater design flexibility than single nanoantennas. This makes them of great interest for engineering optical absorption and emission. Here we study the coupling of a single quantum emitter, a self-assembled semiconductor quantum dot, to a plasmonic meta-surface. We investigate the influence of the spectral properties of the nanoantennas and the position of the emitter in the unit cell of the structure. We observe a resonant enhancement due to emitter-array coupling in the far-field regime and find a clear difference from the interaction of an emitter with a single antenna. PMID- 29467500 TI - A tomato MADS-box protein, SlCMB1, regulates ethylene biosynthesis and carotenoid accumulation during fruit ripening. AB - The MADS-box transcription factors play essential roles in many physiological and biochemical processes of plants, especially in fruit ripening. Here, a tomato MADS-box gene, SlCMB1, was isolated. SlCMB1 expression declined with the fruit ripening from immature green to B + 7 (7 days after Breaker) fruits in the wild type (WT) and was lower in Nr and rin mutants fruits. Tomato plants with reduced SlCMB1 mRNA displayed delayed fruit ripening, reduced ethylene production and carotenoid accumulation. The ethylene production in SlCMB1-RNAi fruits decreased by approximately 50% as compared to WT. The transcripts of ethylene biosynthesis genes (ACS2, ACS4, ACO1 and ACO3), ethylene-responsive genes (E4, E8 and ERF1) and fruit ripening-related genes (RIN, TAGL1, FUL1, FUL2, LoxC and PE) were inhibited in SlCMB1-RNAi fruits. The carotenoid accumulation was decreased and two carotenoid synthesis-related genes (PSY1 and PDS) were down-regulated while three lycopene cyclase genes (CYCB, LCYB and LCYE) were up-regulated in transgenic fruits. Furthermore, yeast two-hybrid assay showed that SlCMB1 could interact with SlMADS-RIN, SlMADS1, SlAP2a and TAGL1, respectively. Collectively, these results indicate that SlCMB1 is a new component to the current model of regulatory network that regulates ethylene biosynthesis and carotenoid accumulation during fruit ripening. PMID- 29467501 TI - Parents' considerable underestimation of sugar and their child's risk of overweight. AB - High sugar intake is associated with an increased risk of overweight. For parents, as their children's nutritional gatekeepers, knowledge about sugar is a prerequisite for regulating sugar consumption. Yet little is known about parental ability to estimate the sugar content of foods and beverages and how this ability is associated with children's body mass index (BMI). In 305 parent-child pairs, we investigated to what extent parents systematically under- or overestimate the sugar content of foods and beverages commonly found in children's diets as well as potential associations with children's z-BMI. Parents considerably underestimated the sugar content of most foods and beverages (e.g., 92% of parents underestimated the sugar content of yogurt by, on average, seven sugar cubes). After controlling for parental education and BMI, parental sugar underestimation was significantly associated with a higher risk of their child being overweight or obese (odds ratio = 2.01). There was a small dose-response relationship between the degree of underestimation and the child's z-BMI. These findings suggest that providing easily accessible and practicable knowledge about sugar content through, for instance, nutritional labeling may improve parents' intuition about sugar. This could help curtail sugar intake in children and thus be a preventive measure for overweight. PMID- 29467503 TI - Optimism for Africa. PMID- 29467502 TI - CDH13 abundance interferes with adipocyte differentiation and is a novel biomarker for adipose tissue health. AB - BACKGROUND: CDH13, an atypical member of the cadherin superfamily, has been identified in adipocyte secretomes of lean mouse models. CDH13 abundance differs in mouse models according to their susceptibility to develop metabolic disorders, but the role of CDH13 in adipose tissue is unknown. METHODS: Secreted CDH13 protein levels and mRNA levels in visceral adipose tissue were determined in lean and obese mouse models. In vitro studies were performed in 3T3-L1 adipocytes to determine the role of CDH13 in adipocyte differentiation. The pathophysiological impact of visceral adipose tissue CDH13 mRNA and circulating CDH13 levels were determined in humans (normal-weight men n = 37, obese men n = 109 including n = 51 type 2 diabetes patients) and in obese patients (n = 14) pre- and post metabolic surgery. RESULTS: This study shows that in visceral adipose tissue CDH13 protein secretion and mRNA levels were decreased in obese mouse models. Mechanistically, CDH13 affects lipid metabolism during adipogenesis but not in mature adipocytes. CDH13 knockdown during adipogenesis reduced fatty acid uptake and lipid content in developing adipocytes. Furthermore, CDH13 depletion during adipogenesis lowered the induction of PPARgamma and C/EBPalpha expression. These observations are of pathophysiological impact since visceral adipose tissue CDH13 mRNA and circulating CDH13 levels were decreased in obese men compared to normal weight controls. Weight loss induced by bariatric surgery restored circulating CDH13 to levels found in normal-weight controls. CONCLUSIONS: CDH13 levels in adipose tissue and the circulation are affected by obesity in mouse models and humans and are restored by weight loss in humans. CDH13 interferes with the differentiation potential of adipocytes and therefore is a marker for plasticity of fat tissue that might reflect the health status of adipose tissue. PMID- 29467505 TI - Still seeking coherence. PMID- 29467504 TI - Imaging the atomic structure and local chemistry of platelets in natural type Ia diamond. AB - In the past decades, many efforts have been devoted to characterizing {001} platelet defects in type Ia diamond. It is known that N is concentrated at the defect core. However, an accurate description of the atomic structure of the defect and the role that N plays in it is still unknown. Here, by using aberration-corrected transmission electron microscopy and electron energy-loss spectroscopy we have determined the atomic arrangement within platelet defects in a natural type Ia diamond and matched it to a prevalent theoretical model. The platelet has an anisotropic atomic structure with a zigzag ordering of defect pairs along the defect line. The electron energy-loss near-edge fine structure of both carbon K- and nitrogen K-edges obtained from the platelet core is consistent with a trigonal bonding arrangement at interstitial sites. The experimental observations support an interstitial aggregate mode of formation for platelet defects in natural diamond. PMID- 29467506 TI - A thirst for advancement.

AB - Light-flavour Baijiu is a type of Chinese liquor with a pure and mild flavour produced by traditional spontaneous solid-state fermentation. The flavour of this liquor has been found to vary in the different periods of annual production. To explore the factors affecting flavour, the microbiota of the surrounding environment, starter and fermentation process in different periods were investigated. Results showed that the ester content and acidity of light-flavour Baijiu were significantly lower when annual production was resumed after a summer break. HCA plot of volatile flavour profile and bacterial PCoA results indicated that the differences occurred at later stages, mainly due to different structures of Lactobacillus. Correlation analysis by O2PLS indicated that Lactobacillus positively correlated with esters. Species-level analysis showed that the lack of L. acetotolerans on the surface of the jar might cause a lag in fermentation and lower ester content. Thereafter, L. acetotolerans was revived during fermentation and enriched on the surface of the jar, which promoted ester formation. As important sources of L. acetotolerans, the air and fermentation jars played a critical role during fermentation. Therefore, this systematic study on environmental microbial ecology is valuable for quality control and to explore environmental microbiota functions during spontaneous fermentation. PMID- 29467509 TI - Magnesium enhances the chondrogenic differentiation of mesenchymal stem cells by inhibiting activated macrophage-induced inflammation. AB - Magnesium deficiency increases the generation of pro-inflammatory cytokines, which is consistently accompanied by the sensitization of cells such as neutrophils, macrophages and endothelial cells. We investigated the potential of magnesium to regulate macrophage polarization and macrophage-induced inflammation with or without lipopolysaccharide (LPS) and interferon-gamma (IFN-gamma) activation and further elucidated whether these effects impact the inhibitory functions of activated macrophage-induced inflammation on cartilage regeneration. The results showed that magnesium inhibited the activation of macrophages, as indicated by a significant reduction in the percentage of CCR7-positive cells, while the percentage of CD206-positive cells decreased to a lesser degree. After activation, both pro-inflammatory and anti-inflammatory cytokines were down regulated at the mRNA level and certain cytokines (IL-1beta, IL-6 and IL-10) were decreased in the cell supernatant with the addition of magnesium. Moreover, magnesium decreased the nuclear translocation and phosphorylation of nuclear factor-kappaB (NF-kappaB) to impede its activation. A modified micromass culture system was applied to assess the effects of activated macrophage-conditioned medium with or without magnesium treatment on the chondrogenic differentiation of human bone marrow mesenchymal stem cells (hBMSCs). Magnesium enhanced the chondrogenic differentiation of hBMSCs by reversing the adverse effects of activated macrophage-induced inflammation. PMID- 29467510 TI - Three dimensional metal/N-doped nanoplate carbon catalysts for oxygen reduction, the reason for using a layered nanoreactor. AB - A layered nanoreactor (zinc hydroxide gallate/nitrate nanohybrid) has been designed as a nano-vessel to confine the gallate/nitrate reaction inside zinc hydroxide layers for production of metal/nitrogen-doped carbon catalysts. Metals (Fe2+, Co2+ and Ni2+) doped and bare zinc hydroxide nitrates (ZHN) were synthesized as the alpha-phase hydroxide hosts. By an incomplete ion-exchange process, nitrate anions between the layers of the hosts were then partially replaced by the gallate anions to produce the layered nanoreactors. Under heat treatment, the reaction between the remaining un-exchanged nitrate anions and the organic moiety inside the basal spacing of each nanohybrid plate resulted in obtaining highly porous 3D metal/nitrogen-doped carbon nanosheets. These catalysts were then used as extremely efficient electrocatalysts for catalyzing oxygen reduction reaction (ORR). This study is intended to show the way to get maximum electrocatalytic activity of the metal/N-doped carbon catalysts toward the ORR. This exceptionally high ORR performance originates from the increased available surface, the best pore size range and the uniform distribution of the active sites in the produced catalysts, all provided by the use of new idea of the layered nanoreactor. PMID- 29467511 TI - Difference in anisotropic etching characteristics of alkaline and copper based acid solutions for single-crystalline Si. AB - The so called inverted pyramid arrays, outperforming conventional upright pyramid textures, have been successfully achieved by one-step Cu assisted chemical etching (CACE) for light reflection minimization in silicon solar cells. Due to the lower reduction potential of Cu2+/Cu and different electronic properties of different Si planes, the etching of Si substrate shows orientation-dependent. Different from the upright pyramid obtained by alkaline solutions, the formation of inverted pyramid results from the coexistence of anisotropic etching and localized etching process. The obtained structure is bounded by Si {111} planes which have the lowest etching rate, no matter what orientation of Si substrate is. The Si etching rate and (100)/(111) etching ratio are quantitatively analyzed. The different behaviors of anisotropic etching of Si by alkaline and Cu based acid etchant have been systematically investigated. PMID- 29467512 TI - Energy storage in structural composites by introducing CNT fiber/polymer electrolyte interleaves. AB - This work presents a method to produce structural composites capable of energy storage. They are produced by integrating thin sandwich structures of CNT fiber veils and an ionic liquid-based polymer electrolyte between carbon fiber plies, followed by infusion and curing of an epoxy resin. The resulting structure behaves simultaneously as an electric double-layer capacitor and a structural composite, with flexural modulus of 60 GPa and flexural strength of 153 MPa, combined with 88 mF/g of specific capacitance and the highest power (30 W/kg) and energy (37.5 mWh/kg) densities reported so far for structural supercapacitors. In situ electrochemical measurements during 4-point bending show that electrochemical performance is retained up to fracture, with minor changes in equivalent series resistance for interleaves under compressive stress. En route to improving interlaminar properties we produce grid-shaped interleaves that enable mechanical interconnection of plies by the stiff epoxy. Synchrotron 3D X ray tomography analysis of the resulting hierarchical structure confirms the formation of interlaminar epoxy joints. The manuscript discusses encapsulation role of epoxy, demonstrated by charge-discharge measurements of composites immersed in water, a deleterious agent for ionic liquids. Finally, we show different architectures free of current collector and electrical insulators, in which both CNT fiber and CF act as active electrodes.

PMID- 29467514 TI - Could electrohysterography be the solution for external uterine monitoring in obese women? AB - OBJECTIVE: To evaluate the influence of maternal obesity on the performance of external tocodynamometry and electrohysterography. STUDY DESIGN: In a 2-hour measurement during term labor, uterine contractions were simultaneously measured by electrohysterography, external tocodynamometry, and intra-uterine pressure catheter. The sensitivity was compared between groups based on obesity (non obese/obese/morbidly obese) or uterine palpation (good/moderate/poor), and was correlated to maternal BMI and abdominal circumference. RESULT: We included 14 morbidly obese, 18 obese, and 20 non-obese women. In morbidly obese women, the median sensitivity was 87.2% (IQR 74-93) by electrohysterography and 45.0% (IQR 36-66) by external tocodynamometry (p < 0.001). The sensitivity of electrohysterography appeared to be non-influenced by obesity category (p = 0.279) and uterine palpation (p = 0.451), while the sensitivity of tocodynamometry decreased significantly (p = 0.005 and p < 0.001, respectively). Furthermore, the sensitivity of both external methods was negatively correlated with obesity parameters, being non-significant for electrohysterography (range p values 0.057-0.088) and significant for external tocodynamometry (all p-values < 0.001). CONCLUSIONS: Electrohysterography performs significantly better than external tocodynamometry in case of maternal obesity. PMID- 29467515 TI - Infant size and the association between maternal circulating angiogenic factors and preeclampsia. AB - OBJECTIVE: To assess the effect of infant size as a marker of placental function on the association between preeclampsia and the ratio of soluble fms-like tyrosine kinase 1 (sFlt-1) to placental growth factor (PlGF). STUDY DESIGN: The angiogenic factors sFlt-1 and PlGF were measured prospectively at 26 weeks gestation in 2322 women. Pregnancies were stratified by whether or not they were complicated by preeclampsia, the timing of delivery, and birthweight Z-score. RESULT: Independent of preeclampsia status, women with small infants (Z < -1.0) have an increased sFlt-1/PlGF ratio, and women with large infants (Z > 1.0) have a decreased ratio. Among pregnancies yielding small infants, the sFlt-1/PlGF ratio is markedly elevated in preeclamptic pregnancies requiring delivery before 37 weeks (110.0 vs. 17.9, p < 0.0001) but not in preeclamptic pregnancies delivered at term. The strength of the association between preeclampsia and the sFlt-1/PlGF ratio is increased for small infants compared to normal-sized or large infants. CONCLUSION: The sFlt-1/PlGF ratio in the late second trimester is similarly elevated in women with preeclampsia and in women with small infant size and more markedly elevated in a syndrome of placental dysfunction characterized by preeclampsia, preterm delivery, and growth restriction. PMID- 29467516 TI - Packed red blood cells transfusion in neonates: effect on FiO2 and PaO2/SaO2 ratio, and implications for neonatal saturation targeting. AB - OBJECTIVE: To assess the effect of blood transfusions in neonates on partial pressure of oxygen in arterial blood (PaO2), arterial hemoglobin oxygen saturation (SaO2) and arterial hemoglobin oxygen saturation as measured by pulse oximetry (SpO2). STUDY DESIGN: Retrospective study of neonates that received a first blood transfusion while having an indwelling arterial line. We compared PaO2, SaO2, SpO2, SaO2/PaO2 ratio and fraction of inspired oxygen (FiO2) 12 h before and after blood transfusion. RESULTS: Post-transfusion neonates had higher PaO2 and SaO2, had lower SaO2/PaO2 ratio, and received higher FiO2 with no change in SpO2. CONCLUSIONS: Post-transfusion, neonates had lower hemoglobin oxygen affinity. They received higher FiO2 and had higher PaO2 at the same SpO2. We speculate that FiO2 was increased in order to maintain SpO2. Larger prospective trials are needed to confirm our findings.

AB - OBJECTIVE: Abnormal umbilical cord coiling is associated with adverse perinatal outcomes; however, the etiology of the umbilical coiling pattern is poorly understood. STUDY DESIGN: Retrospective cohort of all twin deliveries >20 weeks in 2014. Pregnancies were dichotomized by chorionicity and the umbilical coiling index (UCI) and placental cord insertion location were compared. In cases with one or both cords hypercoiled, the direction and pattern of coiling were compared by chorionicity. A similar analysis was performed stratified by zygosity. RESULTS: Three hundred sisty two twin pairs were included; 26 (7.2%) monochorionic and 174 (87.0%) definitively dizygotic. Concordance in the UCI and coiling category were similar between dichorionic and monochorionic as well as dizygous and monozygous gestations, (73.2% vs 80.8%, p = 0.399 and 71.4% vs 80.8%, p = 0.399, respectively). Analyses of the coiling direction and pattern also demonstrated no difference by chorionicity or zygosity. CONCLUSION: These data do not support a genetic basis for umbilical cord coiling.

PMID- 29467520 TI - Premedication with paralysis improves intubation success and decreases adverse events in very low birth weight infants: a prospective cohort study. AB - OBJECTIVE: To characterize the impact of premedication with and without a paralytic agent on the safety of tracheal intubation (TI) in infants <=1500 g. STUDY DESIGN: A prospective observational cohort study between February 2015 and June 2017. The primary outcomes were associations between the use of different premedication regimens with number of TI attempts, TI adverse events (TIAEs), and changes in heart rate. RESULTS: Data were collected on 237 TIs. Median postmenstrual age at intubation was 28 completed weeks and weight was 953 g. Premedication with a paralytic was associated with fewer intubation attempts compared to premedication without a paralytic (p = 0.037). Premedication with a paralytic was associated with fewer TIAEs (p < 0.001) and less bradycardia compared to the other two regimens (p = 0.003) compared to premedication without a paralytic. CONCLUSIONS: Premedication with a paralytic was associated with fewer intubation attempts, fewer TIAEs, and less bradycardia. Premedication with a paralytic may improve intubation safety in VLBWs.

PMID- 29467521 TI - Rapid resolution of hyperammonemia in neonates using extracorporeal membrane oxygenation as a platform to drive hemodialysis. AB - OBJECTIVE: We aimed to clarify the impact of extracorporeal membrane oxygenation (ECMO) as a platform to drive hemodialysis (HD) for ammonia clearance on outcomes of neonates with severe hyperammonemia. STUDY DESIGN: All neonates treated for hyperammonemia at a single children's hospital between 1992 and 2016 were identified. Patient characteristics and outcomes were compared between those receiving medical management or ECMO/HD. RESULT: Twenty-five neonates were treated for hyperammonemia, of which 13 (52%) received ECMO/HD. Peak ammonia levels among neonates treated with ECMO/HD were significantly higher than those medically managed (1041 [IQR 902-1581] MUmol/L versus 212 [IQR 110-410] MUmol/L; p = 0.009). Serum ammonia levels in the ECMO/HD cohort declined to the median of medically managed within 4.5 (IQR 2.9-7.0) hours and normalized within 7.3 (IQR 3.6-13.5) hours. All neonates survived ECMO/HD, and nine (69.2%) survived to discharge. CONCLUSION: ECMO/HD is an effective adjunct to rapidly clear severe hyperammonemia in newborns, reducing potential neurodevelopmental morbidity. PMID- 29467523 TI - Early low-dose hydrocortisone: is the neurodevelopment affected? AB - TYPE OF INVESTIGATION: Prognosis; exploratory secondary analysis of an interventional randomized controlled trial. QUESTION: In extremely preterm infant (<28 weeks), is early low-dose hydrocortisone compared to placebo associated with neurodevelopmental impairment at 2 years of age? METHODS: Patients: Surviving infants enrolled in the PREMILOC trial conducted in France between 2008 and 2014. INTERVENTION: Double-blind, multicenter, randomized, placebo-controlled trial of infants born between 24 0/7 weeks and 27 6/7 weeks of gestation and before 24 h of postnatal age, assigned to receive either placebo or low-dose hydrocortisone (0.5 mg/kg twice per day for 7 days, followed by 0.5 mg/kg per day for 3 days). MAIN RESULTS: For the pre-specified exploratory outcome, the distribution of patients without neurodevelopmental impairment (73% in the hydrocortisone group vs. 70% in the placebo group), with mild neurodevelopmental impairment (20% in the hydrocortisone group vs. 18% in the placebo group), or with moderate to severe neurodevelopmental impairment (7% in the hydrocortisone group vs. 11% in the placebo group) was not found to be statistically significantly different between the two groups (p = 0.33). Qualitative assessment of patients using standardized neurological examination also was not statistically significantly different between groups (p = 0.87). STUDY CONCLUSION: In this follow-up study of premature infants who were randomly assigned at birth to receive low-dose hydrocortisone or placebo for 10 days, hydrocortisone treatment was not associated with any adverse effects on neurodevelopmental outcome at 22 months of corrected age.

In this large, population-based cohort from northern France, the rapid increase in pediatric CD and UC from 1988-2011 may be due to multiple potential etiologies including environmental factors and advancements in diagnostic capabilities. We should consider the clinical implications of this rise in incidence, including potential risk stratification approaches that may offer the ability to modify the disease course of patients with earlier diagnosis. PMID- 29467540 TI - Identification of a novel microRNA-mRNA regulatory biomodule in human prostate cancer. AB - Our recent study identified a list of differentially expressed microRNAs (miRNAs) in human prostate cancer (PCa) tissues compared to adjacent benign prostate tissues. In the current study, to identify the crucial miRNA-mRNA regulatory biomodule involved into prostate carcinogenesis based on the previous miRNA expression profile in PCa, we proposed an integrated systematic approach which combined miRNA-mediated gene expression regulatory network analysis, experimental validations in vitro and in vivo, as well as clinical significance evaluation. As a result, the CCND1-RNASEL-CDKN1A-TP73-MDM2-UBE2I axis was identified as a bottleneck in the miRNA-mediated gene expression regulatory network of PCa according to network topological analysis. The direct binding relationship between TP73 and PCa downregulated miR-193a-5p, and the direct binding relationship between UBE2I and PCa upregulated miR-188-5p were both experimentally validated. In addition, miR-193a-5p had a more significant regulatory effect on the tumor promoter isoform of TP73-deltaNp73 than on the tumor suppressive isoform of TP73-TAp73. Importantly, the deregulation of either the miR-193a-5p-TP73 or miR-188-5p-UBE2I axes was significantly associated with aggressive progression and poor prognosis in PCa patients. Gain- and loss-of function experiments showed that miR-193a-5p efficiently inhibited in vitro PCa cell proliferation, migration, and invasion, and in vivo tumor growth, and markedly induced PCa cell apoptosis via regulating TP73 with a corresponding suppression of the CCND1-RNASEL-CDKN1A-MDM2 axis. In contrast, miR-188-5p exerted its tumor promoter roles through targeting UBE2I with a subsequent activation of the CCND1-RNASEL-CDKN1A-MDM2 axis. Taken together, this integrated analysis revealed the potential roles of the miR-193a-5p/TP73 and miR-188-5p/UBE2i negative regulation pairs in PCa. In addition to the significant clinical relevance, miR-193a-5p- and miR-188-5p-regulated CCND1-RNASEL-CDKN1A-TP73-MDM2 UBE2I signaling may be a novel regulatory biomodule in prostate carcinogenesis.

AB - Vascular calcification is a pathologic response to mineral imbalances and is prevalent in atherosclerosis, diabetes mellitus, and chronic kidney disease. When located in the media, it is highly associated with increased cardiovascular morbidity and mortality, particularly in patients on dialysis. Vascular calcification is tightly regulated and controlled by a series of endogenous factors. In the present study, we assess the effects of lysosomal and endosomal inhibition on calcification in vascular smooth muscle cells (VSMCs) and aortic rings. We observed that lysosomal function was increased in VSMCs cultured in calcification medium containing 3.5 mM inorganic phosphate (Pi) and 3 mM calcium (Ca2+) for 7 days. We also found that the lysosomal marker lysosome-associated membrane protein 2 was markedly increased and colocalized with osteogenic markers in calcified aortas from vitamin D3-treated rats. Interestingly, both the lysosomal inhibitor chloroquine and the endosomal inhibitor dynasore dose dependently enhanced Pi + Ca2+-mediated VSMC calcification. Inhibition of lysosomal and endosomal function also promoted osteogenic transformation of VSMCs. Additionally, lysosome inhibition increased Pi-induced medial calcification of aortic rings ex vivo. These data suggest that the endosome lysosome system may play a protective role in VSMC and medial artery calcification. PMID- 29467542 TI - Tubulation repair mitigates misdirection of regenerating motor axons across a sciatic nerve gap in rats. AB - The repair of peripheral nerve laceration injury to obtain optimal function recovery remains a big challenge in the clinic. Misdirection of regenerating axons to inappropriate target, as a result of forced mismatch of endoneurial sheaths in the case of end-to-end nerve anastomosis or nerve autografting, represents one major drawback that limits nerve function recovery. Here we tested whether tubulation repair of a nerve defect could be beneficial in terms of nerve regeneration accuracy and nerve function. We employed sequential retrograde neuronal tracing to assess the accuracy of motor axon regeneration into the tibial nerve after sciatic nerve laceration and entubulation in adult Sprague Dawley rats. In a separate cohort of rats with the same sciatic nerve injury/repair protocols, we evaluated nerve function recovery behaviorally and electrophysiologically. The results showed that tubulation repair of the lacerated sciatic nerve using a 3-6-mm-long bioabsorbable guidance conduit significantly reduced the misdirection of motor axons into the tibial nerve as compared to nerve autografting. In addition, tubulation repair ameliorated chronic flexion contracture. This study suggests that tubulation repair of a nerve laceration injury by utilizing a bioresorbable nerve guidance conduit represents a potential substitute for end-to-end epineurial suturing and nerve autografting. PMID- 29467543 TI - AP-2epsilon Expression in Developing Retina: Contributing to the Molecular Diversity of Amacrine Cells. AB - AP-2 transcription factors play important roles in the regulation of gene expression during development. Four of the five members of the AP-2 family (AP 2alpha, AP-2beta, AP-2gamma and AP-2delta) have previously been shown to be expressed in developing retina. Mouse knockouts have revealed roles for AP 2alpha, AP-2beta and AP-2delta in retinal cell specification and function. Here, we show that the fifth member of the AP-2 family, AP-2epsilon, is also expressed in amacrine cells in developing mammalian and chicken retina. Our data indicate that there are considerably fewer AP-2epsilon-positive cells in the developing mouse retina compared to AP-2alpha, AP-2beta and AP-2gamma-positive cells, suggesting a specialized role for AP-2epsilon in a subset of amacrine cells. AP 2epsilon, which is restricted to the GABAergic amacrine lineage, is most commonly co-expressed with AP-2alpha and AP-2beta, especially at early stages of retinal development. Co-expression of AP-2epsilon and AP-2gamma increases with differentiation. Analysis of previously published Drop-seq data from single retinal cells supports co-expression of multiple AP-2s in the same cell. Since AP 2s bind to their target sequences as either homodimers or heterodimers, our work suggests spatially- and temporally-coordinated roles for combinations of AP-2 transcription factors in amacrine cells during retinal development. PMID- 29467544 TI - Ultrasound detection of diaphragm position in the region for lung monitoring by electrical impedance tomography during laparoscopy. AB - BACKGROUND AND AIMS: During laparoscopic surgery, a capnoperitoneum is created to optimize the operating space for surgeons. One effect of this is abdominal pressure which alters the physiological thoraco-abdominal configuration and pushes the diaphragm and lungs cranially. Since the lung image acquired by electrical impedance tomography (EIT) depends on the conditions within the thorax and abdomen, it is crucial to know the diaphragm position to determine the effect of diaphragm shift on EIT thorax image. METHODS: The presence of diaphragm in the region of EIT measurement was determined by ultrasound in 20 patients undergoing laparoscopic surgery. Data were obtained in the supine position during spontaneous breathing in a mechanically ventilated patient under general anesthesia with muscle relaxation and in a mechanically ventilated patient under general anesthesia with muscle relaxation during capnoperitoneum. RESULTS: The diaphragm was shifted cranially during capnoperitoneum. The diaphragm detection rate rose by 10% during capnoperitoneum at the fifth intercostal space, from 55% to 65% and by 10% from 0% at mid-sternal level compared to mechanical ventilation without capnoperitoneum. CONCLUSION: The diaphragm was detected in the area contributing to the creation of the thoracic EIT image. Considering the cranial shift of diaphragm caused by excessive intra-abdominal pressure, the impedance changes in the abdomen and the principle of EIT, we assume there could be a significant impact on EIT image of the thorax acquired during capnoperitoneum. For this reason, for lung monitoring using EIT during capnoperitoneum, the manufacturer's recommendation for electrode belt position is not appropriate. The study was registered in ClinicalTrials.gov with an identifier NCT03038061. PMID- 29467545 TI - Vulnerable atherosclerotic plaque - a review of current concepts and advanced imaging. AB - Atherosclerosis is the most common cause of both carotid and coronary steno occlusive disease. Rupture of an atherosclerotic plaque may lead to the formation of an overlying thrombosis resulting in complete arterial occlusion or downstream embolism. Clinically, this may manifest as a stroke or acute myocardial infarction, the overall leading causes of mortality and disability in developed countries. In this article, we summarize current concepts of the development of vulnerable plaque and provide an overview of commonly used imaging methods that may suggest/indicate atherosclerotic plaque vulnerability. PMID- 29467546 TI - Chemiluminescent detection of oligoclonal immunoglobulins after isoelectric focusing and affinity-mediated immunoblotting. AB - BACKGROUND AND AIMS: Detection of oligoclonal IgG (o-IgG) in the cerebrospinal fluid (CSF) not found in serum is the principal laboratory test to support a diagnosis of multiple sclerosis. The aim of this study was to compare chemiluminescent and chromogenic detection of oligoclonal immunoglobulins in the cerebrospinal fluid and serum after their separation by means of isoelectric focusing followed by immunoblotting. METHODS: A set of experiments was designed to detect oligoclonal immunoglobulins by means of alkaline phosphatase BCIP/NBT substrate and chemiluminescent peroxidase substrate. RESULTS: Based on visual evaluation of signals, chemiluminescent detection requires about a 4 times lower amount of applied protein than very sensitive BCIP/NBT chromogenic detection. Very good correlation between methods has been shown for oligoclonal IgG. Antigen specific oligoclonal IgG could be demonstrated by both methods although the pattern was clearer using chemiluminescence. In one patient, oligoclonal IgD bands barely visible by BCIP/NBT were convincingly demonstrated by chemiluminescence. CONCLUSION: Chemiluminescent detection is a feasible option for oligoclonal immunoglobulin detection and could be used in cases when the sensitivity needs to be improved. Further studies and method optimisation are warranted. PMID- 29467547 TI - Prescriptive or Interpretive Regulation at the Frontlines of Care Work in the "Three Worlds" of Canada, Germany and Norway. AB - This paper examines the tension between macro level regulation and the rule breaking and rule following that happens at the workplace level. Using a comparative study of Canada, Norway, and Germany, the paper documents how long term residential care work is regulated and organized differently depending on country, regional, and organizational contexts. We ask where each jurisdiction's staffing regulations fall on a prescription-interpretation continuum; we define prescription as a regulatory tendency to identify what to do and when and how to do it, and interpretation as a tendency to delineate what to do but not when and how to do it. In examining frontline care workers' strategies for accomplishing everyday social, health, and dining care tasks we explore how a policy-level prescriptive or interpretive regulatory approach affects the potential for promising practices to emerge on the frontlines of care work. Overall, we note the following associations: prescriptive regulatory environments tend to be accompanied by a lower ratio of professional to non-professional staff, a higher concentration of for-profit providers, a lower ratio of staff to residents and a sharper division of labour. Interpretive regulatory environments tend to have higher numbers of professionals relative to non-professionals, more limited for profit provision, a higher ratio of staff to residents, and a more relational division of labour that enables the work to be more fluid and responsive. The implication of a prescriptive environment, such as is found in Ontario, Canada, is that frontline care workers possess less autonomy to be creative in meeting residents' needs, a tendency towards more task-oriented care and less job autonomy. The paper reveals that what matters is the type of regulation as well as the regulatory tendency towards controlling frontline care workers decision making and decision-latitude. PMID- 29467548 TI - Epidemiology, determinants, and management of AIDS cholangiopathy: A review. AB - Diseases of the liver and biliary tree have been described with significant frequency among patients with human immunodeficiency virus (HIV), and its advanced state, acquired immunodeficiency syndrome (AIDS). Through a variety of mechanisms, HIV/AIDS has been shown to affect the hepatic parenchyma and biliary tree, leading to liver inflammation and biliary strictures. One of the potential hepatobiliary complications of this viral infection is AIDS cholangiopathy, a syndrome of biliary obstruction and liver damage due to infection-related strictures of the biliary tract. AIDS cholangiopathy is highly associated with opportunistic infections and advanced immunosuppression in AIDS patients, and due to the increased availability of highly active antiretroviral therapy, is now primarily seen in instances of poor access to anti-retroviral therapy and medication non-compliance. While current published literature describes well the clinical, biochemical, and endoscopic management of AIDS-related cholangiopathy, information on its epidemiology, natural history, and pathology are not as well defined. The objective of this review is to summarize the available literature on AIDS cholangiopathy, emphasizing its epidemiology, course of disease, and determinants, while also revealing an updated approach for its evaluation and management. PMID- 29467549 TI - Glucose transporter expression in the human colon. AB - AIM: To investigate by immunostaining glucose transporter expression in human colorectal mucosa in controls and patients with inflammatory bowel disease (IBD). METHODS: Colorectal samples were obtained from patients undergoing lower endoscopic colonoscopy or recto-sigmoidoscopy. Patients diagnosed with ulcerative colitis (n = 18) or Crohn's disease (n = 10) and scheduled for diagnostic colonoscopy were enrolled. Patients who underwent colonoscopy for prevention screening of colorectal cancer or were followed-up after polypectomy or had a history of lower gastrointestinal symptoms were designated as the control group (CTRL, n = 16). Inflammatory status of the mucosa at the sampling site was evaluated histologically and/or endoscopically. A total of 147 biopsies of colorectal mucosa were collected and processed for immunohistochemistry analysis. The expression of GLUT2, SGLT1, and GLUT5 glucose transporters was investigated using immunoperoxidase labeling. To compare immunoreactivity of GLUT5 and LYVE-1, which is a marker for lymphatic vessel endothelium, double-labeled confocal microscopy was used. RESULTS: Immunohistochemical analysis revealed that GLUT2, SGLT1, and GLUT5 were expressed only in short epithelial portions of the large intestinal mucosa. No important differences were observed in glucose transporter expression between the samples obtained from the different portions of the colorectal tract and between the different patient groups. Unexpectedly, GLUT5 expression was also identified in vessels, mainly concentrated in specific areas where the vessels were clustered. Immunostaining with LYVE-1 and GLUT5 antibodies revealed that GLUT5-immunoreactive (-IR) clusters of vessels were concentrated in areas internal to those that were LYVE-1 positive. GLUT5 and LYVE-1 did not appear to be colocalized but rather showed a close topographical relationship on the endothelium. Based on their LYVE-1 expression, GLUT5-IR vessels were identified as lymphatic. Both inflamed and non-inflamed mucosal colorectal tissue biopsies from the IBD and CTRL patients showed GLUT5-IR clusters of lymphatic vessels. CONCLUSION: Glucose transporter immunoreactivity is present in colorectal mucosa in controls and IBD patients. GLUT5 expression is also associated with lymphatic vessels. This novel finding aids in the characterization of lymphatic vasculature in IBD patients. PMID- 29467550 TI - Translational pancreatic cancer research: A comparative study on patient-derived xenograft models. AB - AIM: To assess the viability of orthotopic and heterotopic patient-derived pancreatic cancer xenografts implanted into nude mice. METHODS: This study presents a prospective experimental analytical follow-up of the development of tumours in mice upon implantation of human pancreatic adenocarcinoma samples. Specimens were obtained surgically from patients with a pathological diagnosis of pancreatic adenocarcinoma. Tumour samples from pancreatic cancer patients were transplanted into nude mice in three different locations (intraperitoneal, subcutaneous and pancreatic). Histological analysis (haematoxylin-eosin and Masson's trichrome staining) and immunohistochemical assessment of apoptosis (TUNEL), proliferation (Ki-67), angiogenesis (CD31) and fibrogenesis (alpha-SMA) were performed. When a tumour xenograft reached the target size, it was re implanted in a new nude mouse. Three sequential tumour xenograft generations were generated (F1, F2 and F3). RESULTS: The overall tumour engraftment rate was 61.1%. The subcutaneous model was most effective in terms of tissue growth (69.9%), followed by intraperitoneal (57.6%) and pancreatic (55%) models. Tumour development was faster in the subcutaneous model (17.7 +/- 2.6 wk) compared with the pancreatic (23.1 +/- 2.3 wk) and intraperitoneal (25.0 +/- 2.7 wk) models (P = 0.064). There was a progressive increase in the tumour engraftment rate over successive generations for all three models (F1 28.1% vs F2 71.4% vs F3 80.9%, P < 0.001). There were no significant differences in tumour xenograft differentiation and cell proliferation between human samples and the three experimental models among the sequential generations of tumour xenografts. However, a progressive decrease in fibrosis, fibrogenesis, tumour vascularisation and apoptosis was observed in the three experimental models compared with the human samples. All three pancreatic patient-derived xenograft models presented similar histological and immunohistochemical characteristics. CONCLUSION: In our experience, the faster development and greatest number of viable xenografts could make the subcutaneous model the best option for experimentation in pancreatic cancer. PMID- 29467551 TI - Cryopreservation for delayed circulating tumor cell isolation is a valid strategy for prognostic association of circulating tumor cells in gastroesophageal cancer. AB - AIM: To demonstrate the feasibility of cryopreservation of peripheral blood mononuclear cells (PBMCs) for prognostic circulating tumor cell (CTC) detection in gastroesophageal cancer. METHODS: Using 7.5 mL blood samples collected in EDTA tubes from patients with gastroesopheagal adenocarcinoma, CTCs were isolated by epithelial cell adhesion molecule based immunomagnetic capture using the IsoFlux platform. Paired specimens taken during the same blood draw (n = 15) were used to compare number of CTCs isolated from fresh and cryopreserved PBMCs. Blood samples were processed within 24 h to recover the PBMC fraction, with PBMCs used for fresh analysis immediately processed for CTC isolation. Cryopreservation of PBMCs lasted from 2 wk to 25.2 mo (median 14.6 mo). CTCs isolated from pre-treatment cryopreserved PBMCs (n = 43) were examined for associations with clinicopathological variables and survival outcomes. RESULTS: While there was a significant trend to a decrease in CTC numbers associated with cryopreserved specimens (mean number of CTCs 34.4 vs 51.5, P = 0.04), this was predominately in samples with a total CTC count of > 50, with low CTC count samples less affected (P = 0.06). There was no significant association between the duration of cryopreservation and number of CTCs. In cryopreserved PBMCs from patient samples prior to treatment, a high CTC count (> 17) was associated with poorer overall survival (OS) (n = 43, HR = 4.4, 95%CI: 1.7-11.7, P = 0.0013). In multivariate analysis, after controlling for sex, age, stage, ECOG performance status, and primary tumor location, a high CTC count remained significantly associated with a poorer OS (HR = 3.7, 95%CI: 1.2-12.4, P = 0.03). CONCLUSION: PBMC cryopreservation for delayed CTC isolation is a valid strategy to assist with sample collection, transporting and processing. PMID- 29467552 TI - Metformin attenuates motility, contraction, and fibrogenic response of hepatic stellate cells in vivo and in vitro by activating AMP-activated protein kinase. AB - AIM: To investigate the effect of metformin on activated hepatic stellate cells (HSCs) and the possible signaling pathways involved. METHODS: A fibrotic mouse model was generated by intraperitoneal injection of carbon tetrachloride (CCl4) and subsequent treatment with or without metformin. The level of fibrosis was detected by hematoxylin-eosin staining, Sirius Red staining, and immunohistochemistry. The HSC cell line LX-2 was used for in vitro studies. The effect of metformin on cell proliferation (CCK8 assay), motility (scratch test and Transwell assay), contraction (collagen gel contraction assay), extracellular matrix (ECM) secretion (Western blot), and angiogenesis (ELISA and tube formation assay) was investigated. We also analyzed the possible signaling pathways involved by Western blot analysis. RESULTS: Mice developed marked liver fibrosis after intraperitoneal injection with CCl4 for 6 wk. Metformin decreased the activation of HSCs, reduced the deposition of ECM, and inhibited angiogenesis in CCl4-treated mice. Platelet-derived growth factor (PDGF) promoted the fibrogenic response of HSCs in vitro, while metformin inhibited the activation, proliferation, migration, and contraction of HSCs, and reduced the secretion of ECM. Metformin decreased the expression of vascular endothelial growth factor (VEGF) in HSCs through inhibition of hypoxia inducible factor (HIF)-1alpha in both PDGF-BB treatment and hypoxic conditions, and it down-regulated VEGF secretion by HSCs and inhibited HSC-based angiogenesis in hypoxic conditions in vitro. The inhibitory effects of metformin on activated HSCs were mediated by inhibiting the Akt/mammalian target of rapamycin (mTOR) and extracellular signal regulated kinase (ERK) pathways via the activation of adenosine monophosphate activated protein kinase (AMPK). CONCLUSION: Metformin attenuates the fibrogenic response of HSCs in vivo and in vitro, and may therefore be useful for the treatment of chronic liver diseases. PMID- 29467553 TI - Fish oil alleviates liver injury induced by intestinal ischemia/reperfusion via AMPK/SIRT-1/autophagy pathway. AB - AIM: To evaluate whether fish oil (FO) can protect liver injury induced by intestinal ischemia/reperfusion (I/R) via the AMPK/SIRT-1/autophagy pathway. METHODS: Ischemia in Wistar rats was induced by superior mesenteric artery occlusion for 60 min and reperfusion for 240 min. One milliliter per day of FO emulsion or normal saline was administered by intraperitoneal injection for 5 consecutive days to each animal. Animals were sacrificed at the end of reperfusion. Blood and tissue samples were collected for analyses. AMPK, SIRT-1, and Beclin-1 expression was determined in lipopolysaccharide (LPS)-stimulated HepG2 cells with or without FO emulsion treatment. RESULTS: Intestinal I/R induced significant liver morphological changes and increased serum alanine aminotransferase and aspartate aminotransferase levels. Expression of p AMPK/AMPK, SIRT-1, and autophagy markers was decreased whereas tumor necrosis factor-alpha (TNF-alpha) and malonaldehyde (MDA) were increased. FO emulsion blocked the changes of the above indicators effectively. Besides, in LPS stimulated HepG2 cells, small interfering RNA (siRNA) targeting AMPK impaired the FO induced increase of p-AMPK, SIRT-1, and Beclin-1 and decrease of TNF-alpha and MDA. SIRT-1 siRNA impaired the increase of SIRT-1 and Beclin-1 and the decrease of TNF-alpha and MDA. CONCLUSION: Our study indicates that FO may protect the liver against intestinal I/R induced injury through the AMPK/SIRT-1/autophagy pathway. PMID- 29467554 TI - Elderly patients had more severe postoperative complications after pancreatic resection: A retrospective analysis of 727 patients. AB - AIM: To examine the impact of aging on the short-term outcomes following pancreatic resection (PR) in elderly patients. METHODS: A retrospective cohort study using prospectively collected data was conducted at the China National Cancer Center. Consecutive patients who underwent PR from January 2004 to December 2015 were identified and included. 'Elderly patient' was defined as ones age 65 and above. Comorbidities, clinicopathology, perioperative variables, and postoperative morbidity and mortality were compared between the elderly and young patients. Univariate and multivariate analyses were performed using the Cox proportional hazard model for severe postoperative complications (grades IIIb-V). RESULTS: A total of 454 (63.4%) patients were < 65-years-old and 273 (36.6%) patients were >= 65-years-old, respectively. Compared to patients < 65-years-old, elderly patients had worse American Society of Anesthesiologists scores (P = 0.007) and more comorbidities (62.6% vs 32.4%, P < 0.001). Elderly patients had more severe postoperative complications (16.8% vs 9.0%, P = 0.002) and higher postoperative mortality rates (5.5% vs 0.9%, P < 0.001). In the multivariate Cox proportional hazards model for severe postoperative complications, age >= 65 years [hazard ratio (HR) = 1.63; 95% confidence interval (CI): 1.18-6.30], body mass index >= 24 kg/m2 (HR = 1.20, 95%CI: 1.07-5.89), pancreaticoduodenectomy (HR = 4.86, 95%CI: 1.20-8.31) and length of operation >= 241 min (HR = 2.97; 95%CI: 1.04-6.14) were significant (P = 0.010, P = 0.041, P = 0.017 and P = 0.012, respectively). CONCLUSION: We found that aging is an independent risk factor for severe postoperative complications after PR. Our results might contribute to more informed decision-making for elderly patients. PMID- 29467555 TI - Predictors of functional benefit of hepatitis C therapy in a 'real-life' cohort. AB - AIM: To define predictors of functional benefit of direct-acting antivirals (DAAs) in patients with chronic hepatitis C virus (HCV) infection and liver cirrhosis. METHODS: We analysed a cohort of 199 patients with chronic HCV genotype 1, 2, 3 and 4 infection involving previously treated and untreated patients with compensated (76%) and decompensated (24%) liver cirrhosis at two tertiary centres in Germany. Patients were included with treatment initiation between February 2014 and August 2016. All patients received a combination regimen of one or more DAAs for either 12 or 24 wk. Predictors of functional benefit were assessed in a univariable as well as multivariable model by binary logistic regression analysis. RESULTS: Viral clearance was achieved in 88% (175/199) of patients. Sustained virological response (SVR) 12 rates were as follows: among 156 patients with genotype 1 infection the SVR 12 rate was 90% (n = 141); among 7 patients with genotype 2 infection the SVR 12 rate was 57% (n = 4); among 30 patients with genotype 3 infection the SVR 12 rate was 87% (n = 26); and among 6 patients with genotype 4 infection the SVR 12 rate was 67% (n = 4). Follow-up MELD scores were available for 179 patients. A MELD score improvement was observed in 37% (65/179) of patients, no change of MELD score in 41% (74/179) of patients, and an aggravation was observed in 22% (40/179) of patients. We analysed predictors of functional benefit from antiviral therapy in our patients beyond viral eradication. We identified the Child-Pugh score, the MELD score, the number of platelets and the levels of albumin and bilirubin as significant factors for functional benefit. CONCLUSION: Our data may contribute to the discussion of potential risks and benefits of antiviral therapy with individual patients infected with HCV and with advanced liver disease. PMID- 29467556 TI - Predictors of post-treatment stenosis in cervical esophageal cancer undergoing high-dose radiotherapy. AB - AIM: To evaluate toxicity and treatment outcome of high-dose radiotherapy (RT) for cervical esophageal cancer (CEC). METHODS: We reviewed a total of 62 consecutive patients who received definitive RT for stage I to III cervical esophageal cancer between 2001 and 2015. Patients who received < 45 Gy, treated for lesions below sternal notch, treated with palliative aim, treated with subsequent surgical resection, or diagnosed with synchronous hypopharyngeal cancer were excluded. Treatment failures were divided into local (occurring within the RT field), outfield-esophageal, and regional [occurring in regional lymph node(s)] failures. Factors predictive of esophageal stenosis requiring endoscopic dilation were analyzed. RESULTS: Grade 1, 2, and 3 esophagitis occurred in 19 (30.6%), 39 (62.9%), and 4 patients (6.5%), respectively, without grade >= 4 toxicities. Sixteen patients (25.8%) developed post-RT stenosis, of which 7 cases (43.8%) were malignant. Four patients (6.5%) developed tracheoesophageal fistula (TEF), of which 3 (75%) cases were malignant. Factors significantly correlated with post-RT stenosis were stage T3/4 (P = 0.001), complete circumference involvement (P < 0.0001), stenosis at diagnosis (P = 0.024), and endoscopic complete response (P = 0.017) in univariate analysis, while complete circumference involvement was significant in multivariate analysis (P = 0.003). A higher dose (>= 60 Gy) was not associated with occurrence of post RT stenosis or TEF. With a median follow-up of 24.3 (range, 3.4-152) mo, the 2 y local control, outfield esophageal control, progression-free survival, and overall survival (OS) rates were 78.9%, 90.2%, 49.6%, and 57.3%, respectively. Factors significantly correlated with OS were complete circumference involvement (P = 0.023), stenosis at diagnosis (P < 0.0001), and occurrence of post-RT stenosis or TEF (P < 0.001) in univariate analysis, while stenosis at diagnosis (P = 0.004) and occurrence of post-RT stenosis or TEF (P = 0.023) were significant in multivariate analysis. CONCLUSION: Chemoradiation for CEC was well tolerated, and a higher dose was not associated with stenosis. Patients with complete circumferential involvement require close follow-up. PMID- 29467557 TI - Esophageal metastasis of stem cell-subtype hepatocholangiocarcinoma: Rare presentation of a rare tumor. AB - Hepatocholangiocarcinoma (cHCC-ICC) is a rare primary hepatic tumor defined by the presence of histological features of both hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC). Its prevalence ranges from 1%-5% of all primary liver cancers. We report the case of a 55-year-old cirrhotic male patient admitted to our university hospital for dysphagia, revealing a 10 cm lower-third esophageal metastasis of an unresectable cHCC-ICC with stem-cell features. Computed tomography and abdominal magnetic resonance imaging scans revealed multiple hepatic lesions combining features of both HCC and ICC, associated with synchronous bone metastasis. Histological and immunohistochemical analyses of biopsies from the esophageal lesion and the hepatic tumor confirmed the diagnosis of cHCC-ICC with a stem cell-subtype, according to the World Health Organization classification. After a multidisciplinary meeting, the patient was treated with chemotherapy. He received two cycles of a gemcitabine plus cisplatin regimen before bone progression, and he died 3 mo after the initial diagnosis.

The development of the Healthy Congregations Healthy Communities Program (HCHC) was guided through a community-based participatory research lens and included: 1) establishment of a community coalition; 2) identification by coalition members of churches as the best venues for health promotion strategies among African Americans; 3) recruitment of churches; 4) development of a training manual; 5) recruitment and training of congregational health leaders (CHLs); and 6) "Passing of the torch" from the coalition to the CHLs who implemented the intervention in their congregations. We trained 35 CHLs to promote awareness about diabetes and colorectal cancer using a culturally relevant, spiritually based curriculum. Pre- and post-test paired t-tests showed significant increases in CHLs' knowledge of wellness (P<.001), colorectal cancer (P<.002), nutrition (P<.004), and lifestyle changes (P<.005). The community academic partnership was successful in developing a culturally relevant, spiritually based capacity-building program for African American CHLs to implement health promotion strategies in their congregations and communities. PMID- 29467562 TI - Fasting Plasma Glucose and the HbA1c Are Not Optimal Screening Modalities for the Diagnosis of New Diabetes in Previously Undiagnosed Asian Indian Community Participants. AB - Objectives: There is no definitive consensus on the screening algorithm in high risk communities for diabetes. The aims of our study were to determine the prevalence of undiagnosed diabetes in a high-risk community using the oral glucose tolerance test (OGTT), as well as determine the value of anthropometric measurements and other measures of glycemia in the detection of diabetes. Method: All participants from the Phoenix Lifestyle project without known diabetes, and who had undergone an OGTT were selected for study. Anthropometric measurements were collected according to accepted guidelines. Diabetes was diagnosed if fasting plasma glucose (FPG) >=7.0 mmol/l, if 2-hour plasma glucose level during OGTT was >= 11.0 mmol/l, or if HbA1c >= 6.5%. Results: The prevalence of newly diagnosed diabetes was 14.3% (11.7 % age standardized) (women=15.4%; men=11.8%). The prevalence rates were underestimated using FPG criteria, but overestimated when using the HbA1c. The AUC (area under the receiver-operator characteristics curve) was highest for FPG (.879), HbA1c (.855), then anthropometry measures (BMI=.621; waist circumference=.627). For diabetes, at levels >6.3, the discriminant ability (DA) of HbA1c was highest (79%), while a cut-point of >=5.5mmol/l for FPG yielded a DA= 81.5% (82% sensitivity; 81%; specificity of 81%). There was a low level of agreement between the FPG (Kappa = .506), HbA1c (Kappa = .537), and the OGTT. Age- and sex-adjusted independent determinants of diabetes using stepwise backward logistic regression were age, triglyceride levels and a positive family history for diabetes. Conclusion: Neither the HbA1c nor the FPG approached adequate predictive accuracy in the diagnosis of diabetes. In view of the high prevalence of undiagnosed diabetes, this study underscores the need for ongoing national surveillance data. PMID- 29467563 TI - Sociocultural Influences on African Americans' Representations of Type 2 Diabetes: A Qualitative Study. AB - Objective: Illness representations, known as patients' beliefs and expectations about an illness, may be influenced by cultural beliefs and personal experiences. This study explored African Americans' perceptions of the sociocultural factors that influence their representations of diabetes. Design: Six semi-structured focus groups. Setting: Private space at a convenient site. Participants: Forty African Americans, aged 45-60 years with type 2 diabetes for at least one year prior. Results: Participants perceived that there was a race-mediated effect of how they developed diabetes because of poverty due to past slavery, racial discrimination by health care providers, and the stigma associated with diabetes within the African American community. Participants perceived that poverty influenced African Americans' unhealthy eating habits, which led to diabetes diagnosis among their ancestors and their development of the disease since it was hereditary. Participants also perceived that there was provider ill intention, ie, providers were purposefully making people sick, and their lack of education on diabetes from providers was done on purpose, as information on diabetes was withheld and not shared due to racial discrimination. Perceived stigma by the community led to African Americans' avoidance and denial of the disease, and subsequently the development of diabetes. Conclusions: To enhance disease management for African Americans with diabetes, it is important to focus on the sociocultural context of how African Americans view their world that may be influenced by their knowledge of negative historical circumstances and their current provider relationship, which, in turn, may be reflected in their perceptions of diabetes. PMID- 29467564 TI - Determinants of Obesity in Two Urban Communities: Perceptions and Community Driven Solutions. AB - Objective: In the search of solutions to the rising rates of obesity, community perspectives are important because they highlight areas of need and help determine the level of community support for potential interventions. This study aimed to identify community perceptions of factors associated with obesity in two urban municipalities - one racially mixed and one predominantly African American and to explore community-driven solutions to the problem of obesity. Methods: The study used Photovoice methodology to understand what community members perceived as obesity-promoting factors in their residential environments. Results: A total of 96 photographs of factors relevant to obesity were discussed. Most commonly depicted were restaurants, grocery stores, fast food, and fitness centers. In 10 race-stratified focus groups, participants made 592 comments on 12 themes, the most common being restaurants, physical activity, food stores, and proposed solutions. The top three themes - restaurants, physical activity, and food stores - accounted for 58% of all barriers to healthy weight. Proposed solutions ranged from personal efforts and peer support, to educating adults and children, to community action. Conclusions: Interventions addressing the immediate food and physical activity environment - restaurants, grocery stores, and resources for physical activity - may have high likelihood of success as they align with community needs and understanding of priorities. Health education and promotion programs that increase food-related knowledge and skills are also needed and likely to receive strong community support. PMID- 29467565 TI - Racial Differences in Weight Loss Mediated by Engagement and Behavior Change. AB - Objective: We set out to determine if a primarily Internet-delivered behavioral weight loss intervention produced differential weight loss in African American and non-Hispanic White women, and to identify possible mediators. Design: Data for this analysis were from a randomized controlled trial, collected at baseline and 4-months. Setting: The intervention included monthly face-to-face group sessions and an Internet component that participants were recommended to use at least once weekly. Participants: We included overweight or obese African American and non-Hispanic White women (n=170), with at least weekly Internet access, who were able to attend group sessions. Intervention: Monthly face-to-face group sessions were delivered in large or small groups. The Internet component included automated tailored feedback, self-monitoring tools, written lessons, video resources, problem solving, exercise action planning tools, and social support through message boards. Main Outcome Measure: Multiple linear regression was used to evaluate race group differences in weight change. Results: Non-Hispanic White women lost more weight than African American women (-5.03% vs.-2.39%, P=.0002). Greater website log-ins and higher change in Eating Behavior Inventory score in non-Hispanic White women partially mediated the race-weight loss relationship. Conclusions: The weight loss disparity may be addressed through improved website engagement and adoption of weight control behaviors. PMID- 29467566 TI - Prevalence of Self-Reported Chronic Diseases and Health Services Utilization by Ethnic Minorities in Manaus Metropolitan Region. AB - Objectives: To assess the prevalence of, and associated factors to, self-reported chronic diseases and health care utilization by ethnicity in the Manaus Metropolitan Region. Methods: We conducted a cross-sectional, population-based survey from May through August 2015. Using probabilistic sampling in three stages, we recruited adults aged >=18 years. Ethnicity was self-identified as White, Black, Yellow, Brown (Brazilian mixed-race), and Indigenous. We calculated adjusted prevalence ratios (PR) and 95% CI of chronic diseases and health service utilization for each ethnic minority and compared the data using Poisson regression with data from White respondents. Results: In this study, we interviewed 4,001 people. Of these, 15.9% were White, 7.5% Black, 3.4% Yellow, 72.1% Brown, and 1.0% Indigenous. Indigenous respondents had the highest prevalence of self-reported hypertension (29.4%), diabetes (12.3%) and hypercholesterolemia (17.0%) among the ethnic respondent groups. Compared with the White population, Browns had less health insurance coverage (PR=.76; 95% CI: .62-.93) and reported hypertension (PR=.84; 95% CI: .72-0.98) and diabetes (PR=.69; 95% CI: .51-.94) less frequently. Yellows visited the doctor more frequently than Whites (PR=1.13; 95% CI: 1.04-1.22), with no significant difference in prevalence of diseases. Conclusions: Indigenous respondents had higher prevalence rates of the investigated diseases. Compared with Whites, Brown respondents had lower rates of self-reported arterial hypertension and diabetes, as well as lower rates of private health insurance coverage. PMID- 29467567 TI - Acculturation, Mental Health, and Quality of Life among Hispanic Childhood Cancer Survivors: A Latent Class Analysis. AB - Objective: Acculturation appears to be an important aspect of the association between ethnicity and disease, but it has not been explored in depth among childhood cancer survivors (CCS). The purpose of our study was to identify distinct acculturative profiles among Hispanic CCS and to assess differences in quality of life and depressive symptoms. Design: Latent class analysis was used to identify distinct acculturative profiles using 9 indicator items reflecting Hispanic and Anglo cultural orientation. Multinomial logistic regression was performed to explore differences in depressive symptoms and quality of life between acculturation classes. Setting and Participants: Participants were diagnosed in Los Angeles County, California, USA between 2000-2007 and were recruited for the study in 2009. Main Outcome Measures: Center for Epidemiologic Studies depression scale and the PedsQL 4.0 quality of life scale. Results: Three distinct acculturation classes emerged. All classes displayed a high probability of endorsing all Anglo orientation items. One class additionally demonstrated a high probability of endorsing all Hispanic orientation items and was labeled bicultural 40%); another demonstrated low probability of endorsing the Hispanic items so was labeled assimilated (32%); and the last demonstrated a high probability of endorsing only the Hispanic items related to language use and was labeled linguistically Hispanic/culturally Anglo (LH) (28%). Conclusions: The assimilated group had significantly more depressive symptoms and lower quality of life than the other two groups. This may indicate that loss of the Hispanic culture may be associated with poorer psychosocial health among CCS. PMID- 29467568 TI - Commentary: Addressing Racial Disparities in Stroke: The Wide Spectrum Investigation of Stroke Outcome Disparities on Multiple Levels (WISSDOM). AB - Racial-ethnic disparities in stroke recovery are well-established in the United States but the underlying causes are not well-understood. The typical assumption that racial-ethnic disparities in stroke recovery are explained by health care access inequities may be simplistic as access to stroke-related rehabilitation, for example, does not adequately explain the observed disparities. To approach the problem in a more comprehensive fashion, the Wide Spectrum Investigation of Stroke Outcome Disparities on Multiple Levels (WISSDOM) was developed to bring together scientists from Regenerative Medicine, Neurology, Rehabilitation, and Nursing to examine disparities in stroke "recovery." As a result, three related projects (basic science, clinical science and population science) were designed utilizing animal modeling, mapping of brain connections, and community-based interventions. In this article we describe: 1) the goals and objectives of the individual projects; and 2) how these projects could provide critical evidence to explain why racial-ethnic minorities traditionally experience recovery trajectories that are worse than Whites. PMID- 29467569 TI - Ten Basic Rules of Antibody Validation. AB - The quality of research antibodies is an issue for decades. Although several papers have been published to improve the situation, their impact seems to be limited. This publication makes the effort to simplify the description of validation criteria in a way that the occasional antibody user is able to assess the validation level of an immunochemical reagent. A simple, 1-page checklist is supplied for the practical application of these criteria. PMID- 29467570 TI - Reference ranges for antiepileptic drugs revisited: a practical approach to establish national guidelines. AB - Background and objective: Laboratories sometimes use different reference ranges for the same antiepileptic drug (AED), particularly for new and poorly investigated drugs. This may contribute to misunderstandings, concerns or inappropriate dose changes, which in turn may affect therapeutic effect, drug safety or treatment adherence. Therefore, the Norwegian Association of Clinical Pharmacology wished to update and harmonize the reference ranges for AEDs and establish national guidelines for Norway. Methods: A working group collected information on the reference ranges used by Norwegian laboratories for all commonly used AEDs. These reference ranges were compared to recent recommendations by the International League Against Epilepsy, current literature, applicable clinical studies, reference ranges used by leading Northern European epilepsy centers outside of Norway, and routine data derived from Norwegian laboratory databases. Results: Reference ranges varied between laboratories for four of 23 available AEDs (lamotrigine, valproate, eslicarbazepine and oxcarbazepine). For four AEDs (brivaracetam, perampanel, stiripentol and sulthiame), reference ranges had not previously been established. In total, 13 reference ranges were either harmonized, updated or newly established. No changes were applied to the remaining 10 AEDs. Conclusion: Updated and harmonized reference ranges are now available for 22 of the 23 AEDs available in Norway. The exception is vigabatrin (reference range not applicable). Revision of reference ranges is an important part of pharmacovigilance of AEDs and must be a continuous process based on current literature and clinical experience. PMID- 29467571 TI - Vitrectomy in patients 85 years of age and older: surgical outcomes and visual prognosis. AB - Purpose: To evaluate visual and surgical outcomes in very elderly patients (above 85 years of age) undergoing pars plana vitrectomy (PPV). Patients and methods: A single-center, retrospective study was carried out on the medical records of 82 patients aged 85 years and older who had undergone PPV from 2006 to 2013. Patients ranged in age from 86 to 99 years, with a mean age of 88.9 years (+/ 2.88). Visual results and intraoperative and postoperative complications were the main outcome measures. Visual improvement/worsening was defined as at least +/ 0.1 logMAR change. Results: Mean follow-up was 7.25 months (+/-5.35), with a range of 1-28 months. General anesthesia was used in 63% of the operations. The most common indication was retinal detachment (27%). The ocular condition necessitating PPV was secondary to trauma (most commonly after a fall) in 10 eyes (12%). Mean visual acuity (VA) improved from 1/58 preoperatively to 1/29 at the final evaluation (p=0.014). Mean improvement in VA in eyes of patients with the comorbidity of age-related macular degeneration (n=34) was 41% lower compared to eyes of patients without the disease (n=48, p=0.013). In the subgroup of patients operated on for retinal detachment, 45.4% did not reach primary anatomic success and 45.4% needed additional retina-affecting surgery. One or more major ocular complications were reported in 24 eyes (29%), while 19 eyes (23%) had minor ocular complications. Conclusion: Improved VA was documented in more than half of the older adults aged 85-99 undergoing vitrectomy. Despite the rate of complications in the very elderly, the possibility of optimizing visual function may positively affect quality of life in this subgroup. PMID- 29467572 TI - Prevalence of geriatric syndromes among people aged 65 years and older at four community clinics in Moscow. AB - Background: Geriatric syndromes (GSs) are common in older adults and have a significant effect on their quality of life, disability, and use of health care resources. Few studies have assessed the prevalence of GSs in Russia. The aim of this study is to assess the prevalence of GSs among older adults living in the community in Moscow. Methods: A cross-sectional study was conducted in four community clinics in Moscow. A total of 1,220 patients completed a screening questionnaire, and 356 of them also underwent a comprehensive geriatric assessment (CGA). Results: The mean age of the 1,220 participants was 74.9+/-6.1 years; 75.5% were women. Based on the questionnaire, 58.3% reported visual or hearing impairment, 58.2% cognitive impairment, 46% mood disorder, 42% difficulty walking, 28.3% urinary incontinence, 21.3% traumatic falls (over the previous year), and 12.2% weight loss. The mean number of GSs per patient was 2.9+/-1.5. Based on CGA, a decline in Instrumental Activity of Daily Living score was identified in 34.8% of the patients, a risk of malnutrition (Mini-Nutritional Assessment score, 17-23.5) in 25.8%, probable cognitive impairment (Mini-Mental State Examination score <25) in 8.6%, and symptoms of depression (15-item Geriatric Depression Scale score >5) in 36.2%. On the whole, patients demonstrated good mobility (average walking speed, 1+/-0.2 m/s) and hand grip strength (23.9+/-6.4 kg in women and 39.1+/-8.3 kg in men), but poor balance (only 39.4% were able to maintain their balance on one leg for 10 s or more). Conclusion: The results of this study demonstrate a high prevalence of GSs among community-dwelling people aged 65 years and older in Moscow. The results provide a better understanding of the needs of older adults in Russia and can facilitate planning for medical and social assistance for this population. PMID- 29467573 TI - Increased skin permeation efficiency of imperatorin via charged ultradeformable lipid vesicles for transdermal delivery. AB - Aim: The aim of this work was to develop a novel vesicular carrier, ultradeformable liposomes (UDLs), to expand the applications of the Chinese herbal medicine, imperatorin (IMP), and increase its transdermal delivery. Methods: In this study, we prepared IMP-loaded UDLs using the thin-film hydration method and evaluated their encapsulation efficiency, vesicle deformability, skin permeation, and the amounts accumulated in different depths of the skin in vitro. The influence of different charged surfactants on the properties of the UDLs was also investigated. Results: The results showed that the UDLs containing cationic surfactants had high entrapment efficiency (60.32%+/-2.82%), an acceptable particle size (82.4+/-0.65 nm), high elasticity, and prolonged drug release. The penetration rate of IMP in cationic-UDLs was 3.45-fold greater than that of IMP suspension, which was the highest value among the vesicular carriers. UDLs modified with cationic surfactant also showed higher fluorescence intensity in deeper regions of the epidermis. Conclusion: The results of our study suggest that cationic surfactant-modified UDLs could increase the transdermal flux, prolong the release of the drug, and serve as an effective dermal delivery system for IMP. PMID- 29467574 TI - A hydrogel biosensor for high selective and sensitive detection of amyloid-beta oligomers. AB - Background: Alzheimer's disease (AD) is a neurodegenerative disorder characterized by progressive cognitive and memory impairment. It is the most common neurological disease that causes dementia. Soluble amyloid-beta oligomers (AbetaO) in blood or cerebrospinal fluid (CSF) are the pathogenic biomarker correlated with AD. Methods: A simple electrochemical biosensor using graphene oxide/gold nanoparticles (GNPs) hydrogel electrode was developed in this study. Thiolated cellular prion protein (PrPC) peptide probe was immobilized on GNPs of the hydrogel electrode to construct an AbetaO biosensor. Electrochemical impedance spectroscopy was utilized for AbetaO analysis. Results: The specific binding between AbetaO and PrPC probes on the hydrogel electrode resulted in an increase in the electron-transfer resistance. The biosensor showed high specificity and sensitivity for AbetaO detection. It could selectively differentiate AbetaO from amyloid-beta (Abeta) monomers or fibrils. Meanwhile, it was highly sensitive to detect as low as 0.1 pM AbetaO in artificial CSF or blood plasma. The linear range for AbetaO detection is from 0.1 pM to 10 nM. Conclusion: This biosensor could be used as a cost-effective tool for early diagnosis of AD due to its high electrochemical performance and bionic structure. PMID- 29467575 TI - Nanoscale polysaccharide derivative as an AEG-1 siRNA carrier for effective osteosarcoma therapy. AB - Background: Nanomedicine, which is the application of nanotechnology in medicine to make medical diagnosis and treatment more accurate, has great potential for precision medicine. Despite some improvements in nanomedicine, the lack of efficient and low-toxic vectors remains a major obstacle. Objective: The aim of this study was to prepare an efficient and low-toxic vector which could deliver astrocyte elevated gene-1 (AEG-1) small interfering RNA (siRNA; siAEG-1) into osteosarcoma cells effectively and silence the targeted gene both in vitro and in vivo. Materials and methods: We prepared a novel polysaccharide derivative by click conjugation of azidized chitosan with propargyl focal point poly (L-lysine) dendrons (PLLD) and subsequent coupling with folic acid (FA; Cs-g-PLLD-FA). We confirmed the complexation of siAEG-1and Cs-g-PLLD or Cs-g-PLLD-FA by gel retardation assay. We examined the cell cytotoxicity, cell uptake, cell proliferation and invasion abilities of Cs-g-PLLD-FA/siAEG-1 in osteosarcoma cells. In osteosarcoma 143B cells tumor-bearing mice models, we established the therapeutic efficacy and safety of Cs-g-PLLD-FA/siAEG-1. Results: Cs-g-PLLD-FA could completely encapsulate siAEG-1 and showed low cytotoxicity in osteosarcoma cells and tumour-bearing mice. The Cs-g-PLLD-FA/siAEG-1 nanocomplexes were capable of transferring siAEG-1 into osteosarcoma cells efficiently, and the knockdown of AEG-1 resulted in the inhibition of tumour cell proliferation and invasion. In addition, caudal vein injecting of Cs-g-PLLD-FA/siAEG-1 complexes inhibited tumor growth and lung metastasis in tumor-bearing mice by silencing AEG 1 and regulating MMP-2/9. Conclusion: In summary, Cs-g-PLLD-FA nanoparticles are a promising system for the effective delivery of AEG-1 siRNA for treating osteosarcoma. PMID- 29467576 TI - Mitochondrial genome variability: the effect on cellular functional activity. AB - Mitochondria are the key players in cell metabolism, calcium homeostasis, and reactive oxygen species (ROS) production. Mitochondrial genome alterations are reported to be associated with numerous human disorders affecting nearly all tissues. In this review, we discuss the available information on the involvement of mitochondrial DNA (mtDNA) mutations in cell dysfunction. PMID- 29467578 TI - Cholesterol-Binding Sites in GIRK Channels: The Devil is in the Details. AB - In recent years, it has become evident that cholesterol plays a direct role in the modulation of a variety of ion channels. In most cases, cholesterol downregulates channel activity. In contrast, our earlier studies have demonstrated that atrial G protein inwardly rectifying potassium (GIRK) channels are upregulated by cholesterol. Recently, we have shown that hippocampal GIRK currents are also upregulated by cholesterol. A combined computational experimental approach pointed to putative cholesterol-binding sites in the transmembrane domain of the GIRK2 channel, the primary subunit in hippocampal GIRK channels. In particular, the principal cholesterol-binding site was located in the center of the transmembrane domain in between the inner and outer alpha helices of 2 adjacent subunits. Further studies pointed to a similar cholesterol binding site in GIRK4, a major subunit in atrial GIRK channels. However, a close look at a sequence alignment of the transmembrane helices of the 2 channels reveals surprising differences among the residues that interact with the cholesterol molecule in these 2 channels. Here, we compare the residues that form putative cholesterol-binding sites in GIRK2 and GIRK4 and discuss the similarities and differences among them. PMID- 29467577 TI - Human Immunodeficiency Virus in the Brain-Culprit or Facilitator? AB - Introduction: Human immunodeficiency virus (HIV) enters the brain early, where it can persist, evolve, and become compartmentalized. Central nervous system (CNS) disease can be attributed to HIV alone or to the complex interplay between the virus and other neurotropic pathogens. Aim: The current review aims to describe the direct impact of HIV on the brain as well as its relationship with other pathogens from a practitioner's perspective, to provide a general clinical overview, brief workup, and, whenever possible, treatment guidance. Methods: A review of PubMed was conducted to identify studies on neuropathogenesis of HIV in relation to host responses. Furthermore, the interaction between the CNS pathogens and the host damage responses were revised in the setting of advanced and also well-controlled HIV infection. Results: Similar to other pathogens, HIV leads to CNS immune activation, inflammation, and viral persistence. Therefore, almost half of the infected individuals present with neurocognitive disorders, albeit mild. Compartmentalized HIV in the CNS can be responsible in a minority of cases for the dramatic presentation of symptomatic HIV escape. Disruption of the immune system secondary to HIV may reactivate latent infections or allow new pathogens to enter the CNS. Opportunistic infections with an inflammatory component are associated with elevated HIV loads in the cerebrospinal fluid and also with greater cognitive impairment. The inflammatory immune reconstitution syndrome associated with CNS opportunistic infections can be a life-threatening condition, which needs to be recognized and managed by efficiently controlling the pathogen burden and timely balanced combination antiretroviral therapy. Latent neurotropic pathogens can reactivate in the brain and mimic HIV-associated severe neurological diseases or contribute to neurocognitive impairment in the setting of stable HIV infection. Conclusions: As HIV can be responsible for considerable brain damage directly or by facilitating other pathogens, more effort is needed to recognize and manage HIV-associated CNS disorders and to eventually target HIV eradication from the brain. PMID- 29467579 TI - Viral and Bacterial Etiologies of Acute Respiratory Infections Among Children Under 5 Years in Senegal. AB - Acute respiratory infections (ARIs) are the leading cause of infectious disease related morbidity, hospitalization, and morbidity among children worldwide. This study aimed to assess the viral and bacterial causes of ARI morbidity and mortality in children under 5 years in Senegal. Nasopharyngeal samples were collected from children under 5 years who had ARI. Viruses and bacteria were identified using multiplex real-time reverse transcription-polymerase chain reaction and conventional biochemical techniques, respectively. Adenovirus was the most prevalent virus (50%; n = 81), followed by influenza virus (45.68%, n = 74), rhinovirus (40.12%; n = 65), enterovirus (25.31%; n = 41), and respiratory syncytial virus (16.05%; n = 26), whereas Streptococcus pneumoniae (17%; n = 29), Moraxella catarrhalis (15.43%; n = 25), and Haemophilus influenzae (8.02%; n = 13) were the most commonly isolated bacteria. Virus pathogens seem more likely to be more prevalent in our settings and were often associated with bacteria and S. pneumoniae (6%; 16) coinfection. PMID- 29467581 TI - Tetrasomy 18p: case report and review of literature. AB - Tetrasomy 18p syndrome (Online Mendelian Inheritance in Man 614290) is a very rare chromosomal disorder that is caused by the presence of isochromosome 18p, which is a supernumerary marker composed of two copies of the p arm of chromosome 18. Most tetrasomy 18p cases are de novo cases; however, familial cases have also been reported. It is characterized mainly by developmental delays, cognitive impairment, hypotonia, typical dysmorphic features, and other anomalies. Herein, we report de novo tetrasomy 18p in a 9-month-old boy with dysmorphic features, microcephaly, growth delay, hypotonia, and cerebellar and renal malformations. We compared our case with previously reported ones in the literature. Clinicians should consider tetrasomy 18p in any individual with dysmorphic features and cardiac, skeletal, and renal abnormalities. To the best of our knowledge, we report for the first time an association of this syndrome with partial agenesis of cerebellar vermis. PMID- 29467580 TI - History of Morgellons disease: from delusion to definition. AB - Morgellons disease (MD) is a skin condition characterized by the presence of multicolored filaments that lie under, are embedded in, or project from skin. Although the condition may have a longer history, disease matching the above description was first reported in the US in 2002. Since that time, the condition that we know as MD has become a polemic topic. Because individuals afflicted with the disease may have crawling or stinging sensations and sometimes believe they have an insect or parasite infestation, most medical practitioners consider MD a purely delusional disorder. Clinical studies supporting the hypothesis that MD is exclusively delusional in origin have considerable methodological flaws and often neglect the fact that mental disorders can result from underlying somatic illness. In contrast, rigorous experimental investigations show that this skin affliction results from a physiological response to the presence of an infectious agent. Recent studies from that point of view show an association between MD and spirochetal infection in humans, cattle, and dogs. These investigations have determined that the cutaneous filaments are not implanted textile fibers, but are composed of the cellular proteins keratin and collagen and result from overproduction of these filaments in response to spirochetal infection. Further studies of the genetics, pathogenesis, and treatment of MD are warranted. PMID- 29467582 TI - Neoadjuvant chemotherapy among patients treated for nonmetastatic breast cancer in a population with a high HIV prevalence in Johannesburg, South Africa. AB - Background: Neoadjuvant (primary) chemotherapy (NACT) is the standard of care for locally advanced breast cancer. It also allows for the short-term assessment of chemotherapy response; a pathological complete responses correspond to improved long-term breast cancer outcomes. In sub-Saharan Africa, many patients are diagnosed with large nonresectable tumors. We examined NACT use in breast cancer patients who visited public hospitals in Johannesburg, South Africa. Methods: We assessed demographic characteristics, tumor stage and grade, hormone receptor status, and human immunodeficiency virus (HIV) status of female patients diagnosed with nonmetastatic invasive carcinoma of the breast at Chris Hani Baragwanath Academic Hospital between January 1, 2009, and December 31, 2011. The patients received neoadjuvant, adjuvant, or no chemotherapy. Trastuzumab was unavailable. We developed logistic regression models to analyze the factors associated with NACT receipt in these patients. Results: Of 554 women with nonmetastatic breast cancer, the median age at diagnosis was 52 years (range: 28 88 years). Only 5.8% of patients were diagnosed with stage I disease; 49.3% and 44.9% were diagnosed with stages II and III, respectively. Most patients had hormone-responsive tumors: luminal A, 38.1%; luminal B1 (human epidermal growth factor receptor 2 [HER2]-negative and high grade), 12.5%, and luminal B2 (HER2 positive any grade), 11.6%; 11.6% had a HER2-enriched tumor and 20.6% a triple negative tumor. Eighty (14.4%) patients were HIV-positive. In total, 195 patients (35.2%) received NACT, 264 (47.7%) patients received adjuvant chemotherapy, and 95 patients (17.1%) received no chemotherapy, including 62 (11.2%) patients who received only hormonal therapy. Of patients receiving NACT, 125 (64.1%) were evaluable for clinical response. Eighty (64.0%) patients had a clinically significant response; 19 (15.2%) patients had a stable disease, and 26 (20.8%) patients had a progressive disease. Multivariate analysis showed age <40 years and disease stage to be independently associated with the receipt of NACT. Conclusion: Most women receiving NACT with available response data showed a clinical benefit. Stage III disease at diagnosis and age <40 years were predictors of neoadjuvant versus adjuvant chemotherapy treatment. PMID- 29467583 TI - Bone metastasis pattern in initial metastatic breast cancer: a population-based study. AB - Purpose: Bone is one of the most common sites of breast cancer metastasis, and population-based studies of patients with bone metastasis in initial metastatic breast cancer (MBC) are lacking. Materials and methods: From 2010 to 2013, 245,707 breast cancer patients and 8901 patients diagnosed with initial bone metastasis were identified by Surveillance, Epidemiology, and End Results database of the National Cancer Institute. Multivariate logistic and Cox regression were used to identify predictive factors for the presence of bone metastasis and prognosis factors. Kaplan-Meier method and log-rank test were used for survival analysis. Results: Eight thousand nine hundred one patients with initial MBC had bone involvement, accounting for 3.6% of the entire cohort and 62.5% of the patients with initial MBC. Also, 70.5% of patients with bone metastasis were hormone receptor (HR) positive (HR+/human epidermal growth factor receptor 2 [HER2]-: 57.6%; HR+/HER2+: 12.9%). Patients with initial bone metastasis had a better 5-year survival rate compared to those with initial brain, liver, or lung metastasis. HR+/HER2- and HR+/HER2+ breast cancer had a propensity of bone metastasis in the entire cohort and were correlated with better prognosis in patients with initial bone metastasis. Local surgery had significantly improved overall survival in initial MBC patients with bone metastasis. Conclusion: Our study has provided population-based estimates of epidemiologic characteristics and prognosis in patients with bone metastasis at the time of breast cancer diagnosis. These findings would lend support to optimal surveillance and treatment of bone metastasis in breast cancer. PMID- 29467584 TI - PCORnet's Collaborative Research Groups. AB - The Patient-Centered Outcomes Research Institute (PCORI) launched a multi institutional "network of networks" in 2013 - Patient-Centered Clinical Research Network (PCORnet) - that is designed to conduct clinical research that is faster, less expensive, and more responsive to the information needs of patients and clinicians. To enhance cross-network and cross-institutional collaboration and catalyze the use of PCORnet, PCORI has supported formation of 11 Collaborative Research Groups focusing on specific disease types (e.g., cardiovascular health and cancer) or particular patient populations (e.g., pediatrics and health disparities). PCORnet's Collaborative Research Groups are establishing research priorities within these focus areas, establishing relationships with potential funders, and supporting development of specific research projects that will use PCORnet resources. PCORnet remains a complex, multilevel, and heterogeneous network that is still maturing and building a diverse portfolio of observational and interventional people-centered research; engaging with PCORnet can be daunting, particularly for outside investigators. We believe the Collaborative Research Groups are stimulating interest and helping investigators navigate the complexity, but only time will tell if these efforts will bear fruit in terms of funded multicenter PCORnet projects. PMID- 29467585 TI - Integrating Circulating Immunological and Sputum Biomarkers for the Early Detection of Lung Cancer. AB - We have demonstrated that assessments of microRNA (miRNA) expressions in circulating peripheral blood mononucleated cell (PBMC) and sputum specimens, respectively, may help diagnose lung cancer. To assess the individual and combined analysis of the miRNAs across the different body fluids for lung cancer early detection, we analyse a panel of 3 sputum miRNAs (miRs-21, 31, and 210) and a panel of 2 PBMC miRNAs (miRs-19b-3p and 29b-3p) in a discovery cohort of 68 patients with lung cancer and 66 cancer-free smokers. We find that integrating 2 sputum miRNAs (miRs-31 and 210) and 1 PBMC miRNA (miR-19b-3p) has higher sensitivity (86.8%) and specificity (92.4%) compared with the individual panels. The synergistic value of the integrated panel of 3 biomarkers is confirmed in a validation cohort, independent of stage and histological type of lung cancer, and patients' age, sex, and ethnicity. Integrating circulating immunological and sputum biomarkers could improve the early detection of lung cancer. PMID- 29467586 TI - An Observational 1-Month Trial on the Efficacy and Safety of Promerim for Improving Knee Joint. AB - Objective: This study was conducted to evaluate the efficacy and tolerability of the oral intake of promerim in the elimination of acute pain and discomfort associated with knee osteoarthritis (OA). Methods: Single-center, 1-month, prospective, observational clinical trial. A total of 92 patients not older than 70 years were included. Patients were offered to use 720-mg promerim for the first 15 days after admission after breakfast and then 360 mg for the second 15 days. All patients were analyzed with the visual analog scale (VAS) for pain, which ranges from 0 to 10, and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score before the start of treatment and 1 month after the start. Statistical analysis was performed by SPSS 15.0 software. An alpha level of P < .05 was assumed to be statistically significant. Results: This study comprised 92 patients (69 women and 23 men) with a mean age of 51.5 (range: 40-69) years. Before treatment, the mean VAS score was 5.6 +/- 1.1, and after treatment, the mean VAS score was 2.6 +/- 1.7. Treatment with promerim consistently showed a significant decrease in the VAS score (P < .001). The mean WOMAC score of the patients was 46.4 +/- 8.2 before treatment. After treatment, the mean WOMAC score was 72.1 +/- 14.4. Treatment with promerim consistently showed a significant increase in the WOMAC score (P < .001). Conclusions: The results of this single-center, open-label clinical study demonstrate that promerim is a viable natural treatment option for treating knee OA. We recommend that 720-mg promerim taken once daily for the first 15 days after admission and 360 mg taken once daily for the next 15 days significantly and rapidly reduced composite pain and stiffness in the knee OA within 1 month. PMID- 29467587 TI - Management of Tizanidine Withdrawal Syndrome: A Case Report. AB - Most drugs that act on the central nervous system (CNS) require dose titration to avoid withdrawal syndrome. Tizanidine withdrawal syndrome is caused by adrenergic discharge due to its alpha2-agonist mechanism and is characterized by hypertension, reflex tachycardia, hypertonicity, and anxiety. Although tizanidine withdrawal syndrome is mentioned as a potential side effect of cessation, it is not common and there have been few reports. We present the case of a 31-year-old woman with tizanidine withdrawal syndrome after discontinuing medication prescribed for a muscle contracture (tizanidine). She showed high adrenergic activity with nausea, vomiting, generalized tremor, dysthermia, hypertension, and tachycardia. Symptoms were reversed and successful reweaning was achieved by restarting tizanidine followed by slow downward titration. Withdrawal syndrome should be considered when drugs targeting the CNS are suddenly stopped. Weaning regimens should be closely monitored for acute withdrawal reactions. PMID- 29467588 TI - Pulmonary Arterial Enlargement is Associated With Acute Chest Pain in Patients Without Obstructive Coronary Artery Disease. AB - Background: Pulmonary hypertension (PH) is an underdiagnosed cause for chest pain in patients without significant coronary artery disease (CAD). Studies showed that enlarged pulmonary arterial (PA) and right ventricular chamber sizes correlate with the severity of PH. Therefore, we studied the association between chest pain, right ventricular dimensions (RVDs), and PA size on coronary coronary tomographic angiography (CCTA). Methods: The CCTA of 87 patients presenting with chest pain without evidence of obstructive CAD was examined. The PA diameter (PAD), right atrial dimension (RAD), and RVD were measured. A comparative control cohort included 31 patients who presented without cardiopulmonary complaints and underwent thoracic CT. The risk for obstructive sleep apnea (OSA) was assessed using STOP-BANG questionnaires. Results: Patients with chest pain without obstructive CAD showed markedly dilated right atrial and ventricular chambers compared with standard parameters (right atrium: 48 +/- 6.4 mm; right ventricle long axis: 61 +/- 9.5 mm). When comparing chest pain vs non-chest pain group, respectively, the mean PAD measured 25.92 +/- 0.43 mm vs 22.89 +/- 0.38 mm (P < .001), RAD2 measured 40.1423 +/- 0.7108 mm vs 34.8800 +/- 1.0245 mm (P = .0048), and RVD2 measured 31.7729 +/- 0.7299 mm vs 27.6379 +/- 1.6178 mm (P = .034). Chest pain was associated with higher PAD (odds ratio [OR]: 11.11, P < .05) after adjusting for age, sex, body mass index, history of hypertension, hyperlipidemia, congestive heart failure, chronic obstructive pulmonary disease, OSA, and smoking. The chest pain group had a mean STOP-BANG score of 3.9 +/- 1.8 in all patients, and 3.62 +/- 0.20 in patients without known history of OSA, representing an elevated risk index for the disease. Conclusions: In patients presenting with chest pain without obstructive CAD on CCTA, there is a strong association between the presence of chest pain and enlarged PAD. They also represent a high-risk group for OSA. PMID- 29467589 TI - Cabergoline-Induced Pneumocephalus Following Treatment for Giant Invasive Macroprolactinoma Presenting With Spontaneous Cerebrospinal Fluid Rhinorrhea. AB - Cerebrospinal fluid (CSF) rhinorrhea is rarely reported as the first presenting feature of giant invasive macroprolactinomas. Cerebrospinal fluid rhinorrhea is usually reported as a complication of trauma, neurosurgical, and skull-based procedures (such as pituitary surgery or radiations), and less frequently after medical treatment with dopamine agonists (DAs) for macroprolactinomas. This phenomenon results from fistula creation that communicates between the subarachnoid space and the nasal cavity. Meanwhile, pneumocephalus is another well-recognized complication after transsphenoidal surgery for pituitary macroadenomas. This entity may present with nausea, vomiting, headache, dizziness, and more seriously with seizures and/or a decreased level of consciousness if tension pneumocephalus develops. Case reports about the occurrence of spontaneous pneumocephalus after medical treatment with DAs without prior surgical interventions are scarce in the literature. Our index case is a young man who was recently diagnosed with a giant invasive prolactin-secreting pituitary macroadenoma with skull base destruction. A few months before this diagnosis, he presented with spontaneous CSF rhinorrhea with no history of previous medical or surgical treatment. In this case report, we report an uncommon presentation for giant invasive macroprolactinoma with a CSF leak treated with cabergoline that was subsequently complicated by meningitis and pneumocephalus. This is a very rare complication of cabergoline therapy, which occurred approximately 1 month after treatment initiation. PMID- 29467590 TI - PAUSE: A Patient-Centric Tool to Support Patient-Provider Engagement on Menopause. AB - There are powerful demographic, political, and environmental trends shaping women's health. Increases in life expectancy, literacy, and empowerment are fueling expansions in education and advocacy. Research and development focuses on women's health and fertility across an expanded age spectrum. There is also a cultural emphasis on antiaging and aesthetics. In parallel, the digital revolution is changing how health care is accessed by and delivered to women. A women's journey through menopause is at the crossroads of these transformations. Medical and social platforms encourage women to embrace menopause as a pivotal life stage. Yet, many women are reticent to discuss "the transition" due to embarrassment about its symptoms, lack of awareness of its physical manifestations, or fear of aging. We introduce a patient-centric framework to support patient-provider engagement on menopause: prevention, anxiety, urogenital symptoms, vasomotor symptoms, and education. Although not comprehensive, PAUSE represents an acronym and reminder to focus a portion of the medical interaction on menopause. PMID- 29467591 TI - Whole exome sequencing reveals novel somatic alterations in neuroblastoma patients with chemotherapy. AB - Background: We ought to explore the acquired somatic alterations, shedding light on genetic basis of somatic alterations in NB patients with chemotherapy. Methods: Marrow blood samples from NB patients were collected before treatment, after the 2nd and 4th chemotherapy for baseline research and continuous monitoring by whole exome sequencing. Plasma cell free DNA (cfDNA) was prepared for baseline research. Finger nail cells were extracted as self control. The clinical data was analyzed. Results: From December 2014 to February 2016, 27 cases of children with stage IV NB were diagnosed. The follow up time ranged from 5 to 25 months, with a median follow up time of 17 months, 20 patients were stable, one patient died of pulmonary embolism during surgery, six patients died of disease progression. Marrow blood whole exome sequencing demonstrated that several novel somatic mutations were identified in all three trios comply or against the trendy of tumor size variation. Of note, six recurrent mutations in bromodomain PHD finger transcription factor (BPTF) were identified in nine NB patients under the continuous monitoring. The mutation rates variation was positively correlated to tumor size (CC = 0.428, P = 0.021), and patients with BPTF mutation may have a worse prognosis compared with wild type. Meanwhile, CGREF1, CUX2, GP1BA, SLC45A1 and TRA2A were mutated with the trendy oppose as therapeutic effects. The baseline research in three NB patients demonstrated that mutation rate of BPTF, TMCO3, GPRIN2 and C20orf96 in plasma cfDNA were in positive correlation with bone marrow genomic DNA (P = 0.001). Conclusions: Our study showed that BPTF along with other mutations may function as a biomarker for evaluating to effects of chemotherapy to this refractory tumor, and patients with BPTF mutation might have a worse prognosis. PMID- 29467592 TI - Loss of PIM1 correlates with progression and prognosis of salivary adenoid cystic carcinoma (SACC). AB - Background: Increasing evidence indicates that PIM1 is a potential prognostic marker and target for cancer treatment but its precise mechanisms of action remain to be determined in salivary adenoid cystic carcinoma (SACC). This study aims to decipher the prognostic and mechanistic role of PIM1 in progression of SACC cells and tumor tissues. Methods: A SACC cell line (ACC-M) was transfected with shRNA plasmids targeting the PIM1 gene. The expression levels of PIM1, RUNX3 and p21 were measured by quantitative real-time PCR and western blot. Subcellular translocalization of RUNX3 and p21 proteins was assessed using immunofluorescence, and cell cycle phase was quantified using flow cytometry. A total of 97 SACC patients were retrospectively analyzed by clinicopathologic characteristics and survival outcomes. Results: After down-regulation of PIM1 in ACC-M cells, RUNX3 and p21 proteins were translocated from cytoplasm to nucleus, with a decrease of p21 expression and increase of G0/G1 phase cells. PIM1 and RUNX3 levels show a distinct covariance. PIM1 is associated with T-status, lymph node involvement, nerve invasion, and distant metastasis in SACC tissues. Patients with low PIM1 level had a better outcome than those with higher PIM1 level. Conclusions: PIM1 is multifunctional in ACC-M cells and it serves as a neoteric therapeutic target and potential prognostic marker for SACC patients. PMID- 29467593 TI - Depletion of membrane cholesterol compromised caspase-8 imparts in autophagy induction and inhibition of cell migration in cancer cells. AB - Background: Cholesterol in lipid raft plays crucial role on cancer cell survival during metastasis of cancer cells. Cancer cells are reported to enrich cholesterol in lipid raft which make them more susceptible to cell death after cholesterol depletion than normal cells. Methyl-beta-cyclodextrin (MbetaCD), an amphipathic polysaccharide known to deplete the membrane cholesterol, induces cell death selectively in cancer cells. Present work was designed to identify the major form of programmed cell death in membrane cholesterol depleted cancer cells (MDA-MB 231 and 4T1) and its impact on migration efficiency of cancer cells. Methods: Membrane cholesterol alteration and morphological changes in 4T1 and MDA MB 231 cancer cells by MbetaCD were measured by fluorescent microscopy. Cell death and cell proliferation were observed by PI, AO/EB and MTT assay respectively. Programme cell death was confirmed by flow cytometer. Caspase activation was assessed by MTT and PI after treatments with Z-VAD [OME]-FMK, mitomycin c and cycloheximide. Necroptosis, autophagy, pyroptosis and paraptosis were examined by cell proliferation assay and flow cytometry. Relative quantitation of mRNA of caspase-8, necroptosis and autophagy genes were performed. Migration efficiency of cancer cells were determined by wound healing assay. Results: We found caspase independent cell death in cholesterol depleted MDA-MB 231 cells which was reduced by (3-MA) an autophagy inhibitor. Membrane cholesterol depletion neither induces necroptosis, paraptosis nor pyroptosis in MDA-MB 231 cells. Subsequent activation of caspase-8 after co-incubation of mitomycin c and cycloheximide separately, restored the cell viability in cholesterol depleted MDA-MB 231 cells. Down regulation of caspase-8 mRNA in cholesterol depleted cancer cells ensures that caspase-8 indirectly promotes the induction of autophagy. In another experiment we have demonstrated that membrane cholesterol depletion reduces the migration efficiency in cancer cells. Conclusion: Together our experimental data suggests that membrane cholesterol is the crucial for the recruitment and activation of caspase-8 as well as its non apoptotic functions in cancer cells. Enriched cholesterol in lipid raft of cancer cells may be regulating the cross talk between caspase-8 and autophagy machineries to promote their survival and migration. Therefore it can be explored to understand and address the issues of chemotherapeutic and drugs resistance. PMID- 29467594 TI - Catalase down-regulation in cancer cells exposed to arsenic trioxide is involved in their increased sensitivity to a pro-oxidant treatment. AB - Background: Pro-oxidant drugs have been proposed for treating certain cancers but the resistance developed by cancer cells to oxidative stress limits its potential use in clinics. To understand the mechanisms underlying resistance to oxidative stress, we found that the chronic exposure to an H2O2-generating system (ascorbate/menadione, Asc/Men) or catalase overexpression (CAT3 cells) increased the resistance of cancer cells to oxidative stress, likely by increasing the antioxidant status of cancer cells. Methods: Modulation of catalase expression was performed by either protein overexpression or protein down-regulation using siRNA against catalase and aminotriazole as pharmacological inhibitor. The former approach was done by transfecting cells with a plasmid construct containing human catalase cDNA (CAT3 cells, derived from MCF-7 breast cancer cell line) or by generating resistant cells through chronic exposure to an oxidant injury (Resox cells). Cell survival was monitored by using the MTT reduction assay and further calculation of IC50 values. Protein expression was done by Western blots procedures. The formation of reactive oxygen species was performed by flow cytometry. The transcriptional activity of human catalase promoter was assessed by using transfected cells with a plasmid containing the - 1518/+ 16 promoter domain. Results: Using Resox and CAT3 cells (derived from MCF-7 breast cancer cell line) as models for cancer resistance to pro-oxidative treatment, we found that arsenic trioxide (ATO) remarkably sensitized Resox and CAT3 cells to Asc/Men treatment. Since catalase is a key antioxidant enzyme involved in detoxifying Asc/Men (as shown by siRNA-mediated catalase knockdown) that is overexpressed in resistant cells, we hypothesized that ATO might regulate the expression levels of catalase. Consistently, catalase protein level is decreased in Resox cells when incubated with ATO likely by a decreased transcriptional activity of the catalase promoter. Conclusions: Our findings support the proposal that ATO should be administered in combination with pro-oxidant drugs to enhance cancer cell death in solid tumors. PMID- 29467595 TI - Increased ETV4 expression correlates with estrogen-enhanced proliferation and invasiveness of cholangiocarcinoma cells. AB - Background: Cholangiocarcinoma (CCA) is one of the worst prognosis cancer. The survival time of CCA patients is related to serum estrogen levels and estrogen has been found to enhance the proliferation and invasiveness of CCA cells in vitro. This has led to the suggestion that estrogen may play an important role in the progression of CCA. This study tests the relevance of the previous in vitro findings in vivo using a mouse xenograft model of CCA, and investigates possible signaling mechanisms involved. Methods: KKU-213 and KKU-139 CCA cell lines were used in the experiments, xenografted to nude mice and treated with a potent estrogenic agent, 17beta-estradiol (E2), and/or with tamoxifen (TAM), an estrogen antagonist. Results: The results demonstrated that E2 could accelerate growth of the xenograft-tumor and the effect was inhibited by TAM. PCR array screening of E2 responsive genes suggested ETV4 as a promising candidate intracellular mediator. ETV4-knockdown CCA cells were generated and these showed a diminished responsiveness to E2 in both cell and spheroid proliferation assays, and in invasion tests. These results point to ETV4 as a possible mediator of E2 activated CCA progression and as a potential target of TAM-mediated inhibition. Conclusions: Finally, TAM may be suggested as an adjunctive treatment of CCA to improve the conventional cytotoxic method with more patient toleration. PMID- 29467596 TI - Cost-effectiveness of antiviral prophylaxis during pregnancy for the prevention of perinatal hepatitis B infection in South Korea. AB - Background: In Korea, hepatitis B virus (HBV) infection accounts for approximately 65-75% of HBV-related diseases, such as chronic hepatitis and liver cancer, and mother-to-child transmission is presumed to be a major source of the infection. To tackle this issue, the Korean government launched the national Perinatal Hepatitis B Prevention Program (PHBPP) in 2002. This study analyzed the cost-effectiveness of the PHBPP with antiviral prophylaxis compared with the current PHBPP and/or universal vaccination, as well as identified the optimal strategy to eliminate mother-to-child transmission of HBV in Korea. Methods: A decision tree model with the Markov process was developed and simulated over the lifetime of a birth cohort in Korea during the year 2014. The current PHBPP providing HBV vaccine and hepatitis B immune globulin to neonates born to HBV positive mothers was compared against two other strategies, universal vaccination of HBV and PHBPP with antiviral prophylaxis, with respect to their costs and health outcomes. The Korean National Health Insurance database was investigated to estimate the costs of HBV-related diseases and utilization of health resources. Costs were assessed from the health care system perspective and converted to 2014 US dollars. Health outcome measures were quality-adjusted life years (QALYs) and number of HBV-related diseases and deaths. Both costs and QALYs were discounted at 5%, following the recommendation of the Health Insurance Review & Assessment Service in Korea. The incremental cost-effectiveness ratio (ICER) obtained from the analysis was evaluated using the willingness-to-pay (WTP) in the Korean society. Results: PHBPP with antiviral prophylaxis in Korea was cost-effective compared with the current PHBPP. An introduction of antiviral prophylaxis to pregnant women with a high viral load of HBV averted 13 HBV related deaths per 100,000 people and saved 82 QALYs in total (ICER: $16,159/QALY). Conclusions: Considering that WTP in Korea is $29,000, PHBPP with antiviral prophylaxis appears to be a cost-effective strategy. To further decrease the burden of perinatal hepatitis B in Korea, adding antiviral prophylaxis to PHBPP is recommended. PMID- 29467597 TI - [? If it's not documented, it's not done ?: Management indicators of workload can leave women's work invisible]. AB - Historically, eldercare was usually furnished by unpaid women at home. Now that women are in paid work, much of this care is given by personal support workers (PSWs), usually female. With the massive introduction of management indicators in public organisations, a form of organisational silence appears: work is rendered invisible. To examine the mechanism involved, we have observed the work of 37 PSWs in six Ontario residences, and performed interviews. Contrary to the way tasks are assigned, PSW work is often done collectively and documentation requirements are demanding; documenting can even conflict with direct health care. PSWs have insufficient time, so they are sometimes forced to omit data showing the challenges of their work. They thus contribute to a vicious circle where, unable to document the work they do, they lack resources and must skimp even more on documentation. PMID- 29467599 TI - Enstrom's Expose of Air Pollution Epidemiology Problems. PMID- 29467598 TI - An attempt to induce an immunomodulatory effect in rowers with spirulina extract. AB - Background: The aim of this study was to analyze the response of selected components of the immune system in rowers to maximal physical exercise, and to verify if this response can be modulated by supplementation with spirulina (cyanobacterium Spirulina platensis). Method: The double-blind study included 19 members of the Polish Rowing Team. The subjects were randomly assigned to the supplemented group (n = 10), receiving 1500 mg of spirulina extract for 6 weeks, or to the placebo group (n = 9). The participants performed a 2000-m test on a rowing ergometer at the beginning (1st examination) and at the end of the supplementation period (2nd examination). Blood samples were obtained from the antecubital vein prior to each exercise test, 1 min after completing the test, and after a 24-h recovery period. Subpopulations of T regulatory lymphocytes (Tregs) [CD4+/CD25+/CD127-], cytotoxic lymphocytes (CTLs) [CD8+/TCRalphabeta+], natural killer (NK) cells [CD3-/CD16+/CD56+] and TCRdeltagamma-positive (Tdeltagamma) cells were determined by means of flow cytometry. Results: On the 2nd examination, athletes from the supplemented group showed neither a post exercise increase in Treg count nor a post-recovery decrease in Tdeltagamma cell count (both observed in the placebo group), and presented with significantly lower values of Treg/CTL prior to and after the exercise. During the same examination, rowers from the placebo group showed a significant post-recovery increase in Treg/(NK + Tdeltagamma + CTL) ratio, which was absent in the supplemented group. Conclusion: The results of this study imply that supplementation with spirulina extract may protect athletes against a deficit in immune function (especially, anti-infectious function) associated with strenuous exercise, and may cause a beneficial shift in "overtraining threshold" preventing a radical deterioration of immunity. PMID- 29467600 TI - White Matter Tract Segmentation as Multiple Linear Assignment Problems. AB - Diffusion magnetic resonance imaging (dMRI) allows to reconstruct the main pathways of axons within the white matter of the brain as a set of polylines, called streamlines. The set of streamlines of the whole brain is called the tractogram. Organizing tractograms into anatomically meaningful structures, called tracts, is known as the tract segmentation problem, with important applications to neurosurgical planning and tractometry. Automatic tract segmentation techniques can be unsupervised or supervised. A common criticism of unsupervised methods, like clustering, is that there is no guarantee to obtain anatomically meaningful tracts. In this work, we focus on supervised tract segmentation, which is driven by prior knowledge from anatomical atlases or from examples, i.e., segmented tracts from different subjects. We present a supervised tract segmentation method that segments a given tract of interest in the tractogram of a new subject using multiple examples as prior information. Our proposed tract segmentation method is based on the idea of streamline correspondence i.e., on finding corresponding streamlines across different tractograms. In the literature, streamline correspondence has been addressed with the nearest neighbor (NN) strategy. Differently, here we formulate the problem of streamline correspondence as a linear assignment problem (LAP), which is a cornerstone of combinatorial optimization. With respect to the NN, the LAP introduces a constraint of one-to-one correspondence between streamlines, that forces the correspondences to follow the local anatomical differences between the example and the target tract, neglected by the NN. In the proposed solution, we combined the Jonker-Volgenant algorithm (LAPJV) for solving the LAP together with an efficient way of computing the nearest neighbors of a streamline, which massively reduces the total amount of computations needed to segment a tract. Moreover, we propose a ranking strategy to merge correspondences coming from different examples. We validate the proposed method on tractograms generated from the human connectome project (HCP) dataset and compare the segmentations with the NN method and the ROI-based method. The results show that LAP-based segmentation is vastly more accurate than ROI-based segmentation and substantially more accurate than the NN strategy. We provide a Free/OpenSource implementation of the proposed method. PMID- 29467601 TI - The Evolution of Musicality: What Can Be Learned from Language Evolution Research? AB - Language and music share many commonalities, both as natural phenomena and as subjects of intellectual inquiry. Rather than exhaustively reviewing these connections, we focus on potential cross-pollination of methodological inquiries and attitudes. We highlight areas in which scholarship on the evolution of language may inform the evolution of music. We focus on the value of coupled empirical and formal methodologies, and on the futility of mysterianism, the declining view that the nature, origins and evolution of language cannot be addressed empirically. We identify key areas in which the evolution of language as a discipline has flourished historically, and suggest ways in which these advances can be integrated into the study of the evolution of music. PMID- 29467602 TI - Feature Selection Methods for Robust Decoding of Finger Movements in a Non-human Primate. AB - Objective: The performance of machine learning algorithms used for neural decoding of dexterous tasks may be impeded due to problems arising when dealing with high-dimensional data. The objective of feature selection algorithms is to choose a near-optimal subset of features from the original feature space to improve the performance of the decoding algorithm. The aim of our study was to compare the effects of four feature selection techniques, Wilcoxon signed-rank test, Relative Importance, Principal Component Analysis (PCA), and Mutual Information Maximization on SVM classification performance for a dexterous decoding task. Approach: A nonhuman primate (NHP) was trained to perform small coordinated movements-similar to typing. An array of microelectrodes was implanted in the hand area of the motor cortex of the NHP and used to record action potentials (AP) during finger movements. A Support Vector Machine (SVM) was used to classify which finger movement the NHP was making based upon AP firing rates. We used the SVM classification to examine the functional parameters of (i) robustness to simulated failure and (ii) longevity of classification. We also compared the effect of using isolated-neuron and multi-unit firing rates as the feature vector supplied to the SVM. Main results: The average decoding accuracy for multi-unit features and single-unit features using Mutual Information Maximization (MIM) across 47 sessions was 96.74 +/- 3.5% and 97.65 +/ 3.36% respectively. The reduction in decoding accuracy between using 100% of the features and 10% of features based on MIM was 45.56% (from 93.7 to 51.09%) and 4.75% (from 95.32 to 90.79%) for multi-unit and single-unit features respectively. MIM had best performance compared to other feature selection methods. Significance: These results suggest improved decoding performance can be achieved by using optimally selected features. The results based on clinically relevant performance metrics also suggest that the decoding algorithm can be made robust by using optimal features and feature selection algorithms. We believe that even a few percent increase in performance is important and improves the decoding accuracy of the machine learning algorithm potentially increasing the ease of use of a brain machine interface. PMID- 29467603 TI - Cognitive Functions and Neurodevelopmental Disorders Involving the Prefrontal Cortex and Mediodorsal Thalamus. AB - The mediodorsal nucleus of the thalamus (MD) has been implicated in executive functions (such as planning, cognitive control, working memory, and decision making) because of its significant interconnectivity with the prefrontal cortex (PFC). Yet, whilst the roles of the PFC have been extensively studied, how the MD contributes to these cognitive functions remains relatively unclear. Recently, causal evidence in monkeys has demonstrated that in everyday tasks involving rapid updating (e.g., while learning something new, making decisions, or planning the next move), the MD and frontal cortex are working in close partnership. Furthermore, researchers studying the MD in rodents have been able to probe the underlying mechanisms of this relationship to give greater insights into how the frontal cortex and MD might interact during the performance of these essential tasks. This review summarizes the circuitry and known neuromodulators of the MD, and considers the most recent behavioral, cognitive, and neurophysiological studies conducted in monkeys and rodents; in total, this evidence demonstrates that MD makes a critical contribution to cognitive functions. We propose that communication occurs between the MD and the frontal cortex in an ongoing, fluid manner during rapid cognitive operations, via the means of efference copies of messages passed through transthalamic routes; the conductance of these messages may be modulated by other brain structures interconnected to the MD. This is similar to the way in which other thalamic structures have been suggested to carry out forward modeling associated with rapid motor responding and visual processing. Given this, and the marked thalamic pathophysiology now identified in many neuropsychiatric disorders, we suggest that changes in the different subdivisions of the MD and their interconnections with the cortex could plausibly give rise to a number of the otherwise disparate symptoms (including changes to olfaction and cognitive functioning) that are associated with many different neuropsychiatric disorders. In particular, we will focus here on the cognitive symptoms of schizophrenia and suggest testable hypotheses about how changes to MD frontal cortex interactions may affect cognitive processes in this disorder. PMID- 29467604 TI - Investigating Misophonia: A Review of the Empirical Literature, Clinical Implications, and a Research Agenda. AB - Misophonia is a neurobehavioral syndrome phenotypically characterized by heightened autonomic nervous system arousal and negative emotional reactivity (e. g., irritation, anger, anxiety) in response to a decreased tolerance for specific sounds. The aims of this review are to (a) characterize the current state of the field of research on misophonia, (b) highlight what can be inferred from the small research literature to inform treatment of individuals with misophonia, and (c) outline an agenda for research on this topic. We extend previous reviews on this topic by critically reviewing the research investigating mechanisms of misophonia and differences between misophonia and other conditions. In addition, we integrate this small but growing literature with basic and applied research from other literatures in a cross-disciplinary manner. PMID- 29467607 TI - Understanding the Generation of Network Bursts by Adaptive Oscillatory Neurons. AB - Experimental and numerical studies have revealed that isolated populations of oscillatory neurons can spontaneously synchronize and generate periodic bursts involving the whole network. Such a behavior has notably been observed for cultured neurons in rodent's cortex or hippocampus. We show here that a sufficient condition for this network bursting is the presence of an excitatory population of oscillatory neurons which displays spike-driven adaptation. We provide an analytic model to analyze network bursts generated by coupled adaptive exponential integrate-and-fire neurons. We show that, for strong synaptic coupling, intrinsically tonic spiking neurons evolve to reach a synchronized intermittent bursting state. The presence of inhibitory neurons or plastic synapses can then modulate this dynamics in many ways but is not necessary for its appearance. Thanks to a simple self-consistent equation, our model gives an intuitive and semi-quantitative tool to understand the bursting behavior. Furthermore, it suggests that after-hyperpolarization currents are sufficient to explain bursting termination. Through a thorough mapping between the theoretical parameters and ion-channel properties, we discuss the biological mechanisms that could be involved and the relevance of the explored parameter-space. Such an insight enables us to propose experimentally-testable predictions regarding how blocking fast, medium or slow after-hyperpolarization channels would affect the firing rate and burst duration, as well as the interburst interval.

AB - Alzheimer's disease (AD), the most common form of dementia in late life, will become even more prevalent by midcentury, constituting a major global health concern with huge implications for individuals and society. Despite scientific breakthroughs during the past decades that have expanded our knowledge on the cellular and molecular bases of AD, therapies that effectively halt disease progression are still lacking, and focused efforts are needed to address this public health challenge. Because AD is classically recognized as a disease of memory, studies have mainly focused on investigating memory-associated brain defects. However, compelling evidence has indicated that additional brain regions, not classically linked to memory, are also affected in the course of disease. In this review, we outline the current understanding of key pathophysiological mechanisms in AD and their clinical manifestation. We also highlight how considering the complex nature of AD pathogenesis, and exploring repurposed drug approaches can pave the road toward the development of novel therapeutics for AD. PMID- 29467606 TI - Integrating Brain and Biomechanical Models-A New Paradigm for Understanding Neuro muscular Control. AB - To date, realistic models of how the central nervous system governs behavior have been restricted in scope to the brain, brainstem or spinal column, as if these existed as disembodied organs. Further, the model is often exercised in relation to an in vivo physiological experiment with input comprising an impulse, a periodic signal or constant activation, and output as a pattern of neural activity in one or more neural populations. Any link to behavior is inferred only indirectly via these activity patterns. We argue that to discover the principles of operation of neural systems, it is necessary to express their behavior in terms of physical movements of a realistic motor system, and to supply inputs that mimic sensory experience. To do this with confidence, we must connect our brain models to neuro-muscular models and provide relevant visual and proprioceptive feedback signals, thereby closing the loop of the simulation. This paper describes an effort to develop just such an integrated brain and biomechanical system using a number of pre-existing models. It describes a model of the saccadic oculomotor system incorporating a neuromuscular model of the eye and its six extraocular muscles. The position of the eye determines how illumination of a retinotopic input population projects information about the location of a saccade target into the system. A pre-existing saccadic burst generator model was incorporated into the system, which generated motoneuron activity patterns suitable for driving the biomechanical eye. The model was demonstrated to make accurate saccades to a target luminance under a set of environmental constraints. Challenges encountered in the development of this model showed the importance of this integrated modeling approach. Thus, we exposed shortcomings in individual model components which were only apparent when these were supplied with the more plausible inputs available in a closed loop design. Consequently we were able to suggest missing functionality which the system would require to reproduce more realistic behavior. The construction of such closed-loop animal models constitutes a new paradigm of computational neurobehavior and promises a more thoroughgoing approach to our understanding of the brain's function as a controller for movement and behavior. PMID- 29467608 TI - Understanding the Role of Adenosine A2AR Heteroreceptor Complexes in Neurodegeneration and Neuroinflammation. AB - Adenosine is a nucleoside mainly formed by degradation of ATP, located intracellularly or extracellularly, and acts as a neuromodulator. It operates as a volume transmission signal through diffusion and flow in the extracellular space to modulate the activity of both glial cells and neurons. The effects of adenosine are mediated via four adenosine receptor subtypes: A1R, A2AR, A2BR, A3R. The A2AR has a wide-spread distribution but it is especially enriched in the ventral and dorsal striatum where it is mainly located in the striato-pallidal GABA neurons at a synaptic and extrasynaptic location. A number of A2AR heteroreceptor complexes exist in the striatum. The existence of A2AR-D2R heteroreceptor complexes with antagonistic A2AR-D2R interactions in the striato pallidal GABA neurons is well-known with A2AR activation inhibiting Gi/o mediated signaling of D2Rs. A2AR-mGluR5 heteroreceptor complexes were also found in with synergistic receptor-receptor interactions enhancing the inhibition of the D2R protomer signaling. They are located mainly in extrasynaptic regions of the striato-pallidal GABA neurons. Results recently demonstrated the existence of brain A2AR-A2BR heteroreceptor complexes, in which A2BR protomer constitutively inhibited the function of the A2AR protomer. These adenosine A2AR heteroreceptor complexes may modulate alpha-synuclein aggregation and toxicity through postulated bidirectional direct interactions leading to marked increases in A2AR signaling both in nerve cells and microglia. It is of high interest that formation of A2AR-A2ABR heteroreceptor complexes provides a brake on A2AR recognition and signaling opening up a novel strategy for treatment of A2AR mediated neurodegeneration. PMID- 29467609 TI - Phospho-Tau Bar Code: Analysis of Phosphoisotypes of Tau and Its Application to Tauopathy. AB - Tau is a microtubule-associated protein which regulates the assembly and stability of microtubules in the axons of neurons. Tau is also a major component of neurofibrillary tangles (NFTs), a pathological hallmark in Alzheimer's disease (AD). A characteristic of AD tau is hyperphosphorylation with more than 40 phosphorylation sites. Aggregates of hyperphosphorylated tau are also found in other neurodegenerative diseases which are collectively called tauopathies. Although a large number of studies have been performed on the phosphorylation of AD tau, it is not known if there is disease-specific phosphorylation among tauopathies. This is due to the lack of a proper method for analyzing tau phosphorylation in vivo. Most previous phosphorylation studies were conducted using a range of phosphorylation site-specific antibodies. These studies describe relative changes of different phosphorylation sites, however, it is hard to estimate total, absolute and collective changes in phosphorylation. To overcome these problems, we have recently applied the Phos-Tag technique to the analysis of tau phosphorylation in vitro and in vivo. This method separates tau into many bands during SDS-PAGE depending on its phosphorylation states, creating a bar code appearance. We propose calling this banding pattern of tau the "phospho-tau bar code." In this review article, we describe what is newly discovered regarding tau phosphorylation through the use of the Phos-Tag. We would like to propose its use for the postmortem diagnosis of tauopathy which is presently done by immunostaining diseased brains with anti-phospho-antibodies. While Phos-tag SDS PAGE, like other biochemical assays, will lose morphological information, it could provide other types of valuable information such as disease-specific phosphorylation. PMID- 29467610 TI - Open Science Meets Stem Cells: A New Drug Discovery Approach for Neurodegenerative Disorders. AB - Neurodegenerative diseases are a challenge for drug discovery, as the biological mechanisms are complex and poorly understood, with a paucity of models that faithfully recapitulate these disorders. Recent advances in stem cell technology have provided a paradigm shift, providing researchers with tools to generate human induced pluripotent stem cells (iPSCs) from patient cells. With the potential to generate any human cell type, we can now generate human neurons and develop "first-of-their-kind" disease-relevant assays for small molecule screening. Now that the tools are in place, it is imperative that we accelerate discoveries from the bench to the clinic. Using traditional closed-door research systems raises barriers to discovery, by restricting access to cells, data and other research findings. Thus, a new strategy is required, and the Montreal Neurological Institute (MNI) and its partners are piloting an "Open Science" model. One signature initiative will be that the MNI biorepository will curate and disseminate patient samples in a more accessible manner through open transfer agreements. This feeds into the MNI open drug discovery platform, focused on developing industry-standard assays with iPSC-derived neurons. All cell lines, reagents and assay findings developed in this open fashion will be made available to academia and industry. By removing the obstacles many universities and companies face in distributing patient samples and assay results, our goal is to accelerate translational medical research and the development of new therapies for devastating neurodegenerative disorders.

PMID- 29467611 TI - The Vagus Nerve at the Interface of the Microbiota-Gut-Brain Axis. AB - The microbiota, the gut, and the brain communicate through the microbiota-gut brain axis in a bidirectional way that involves the autonomic nervous system. The vagus nerve (VN), the principal component of the parasympathetic nervous system, is a mixed nerve composed of 80% afferent and 20% efferent fibers. The VN, because of its role in interoceptive awareness, is able to sense the microbiota metabolites through its afferents, to transfer this gut information to the central nervous system where it is integrated in the central autonomic network, and then to generate an adapted or inappropriate response. A cholinergic anti inflammatory pathway has been described through VN's fibers, which is able to dampen peripheral inflammation and to decrease intestinal permeability, thus very probably modulating microbiota composition. Stress inhibits the VN and has deleterious effects on the gastrointestinal tract and on the microbiota, and is involved in the pathophysiology of gastrointestinal disorders such as irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD) which are both characterized by a dysbiosis. A low vagal tone has been described in IBD and IBS patients thus favoring peripheral inflammation. Targeting the VN, for example through VN stimulation which has anti-inflammatory properties, would be of interest to restore homeostasis in the microbiota-gut-brain axis. PMID- 29467613 TI - Exercise-Mediated Neurogenesis in the Hippocampus via BDNF. AB - Exercise is known to have numerous neuroprotective and cognitive benefits, especially pertaining to memory and learning related processes. One potential link connecting them is exercise-mediated hippocampal neurogenesis, in which new neurons are generated and incorporated into hippocampal circuits. The present review synthesizes the extant literature detailing the relationship between exercise and hippocampal neurogenesis, and identifies a key molecule mediating this process, brain-derived neurotrophic factor (BDNF). As a member of the neurotrophin family, BDNF regulates many of the processes within neurogenesis, such as differentiation and survival. Although much more is known about the direct role that exercise and BDNF have on hippocampal neurogenesis in rodents, their corresponding cognitive benefits in humans will also be discussed. Specifically, what is known about exercise-mediated hippocampal neurogenesis will be presented as it relates to BDNF to highlight the critical role that it plays. Due to the inaccessibility of the human brain, much less is known about the role BDNF plays in human hippocampal neurogenesis. Limitations and future areas of research with regards to human neurogenesis will thus be discussed, including indirect measures of neurogenesis and single nucleotide polymorphisms within the BDNF gene. PMID- 29467614 TI - Safety and Efficacy of Scanning Ultrasound Treatment of Aged APP23 Mice. AB - Deposition of amyloid-beta (Abeta) peptide leads to amyloid plaques that together with tau deposits characterize the brains of patients with Alzheimer's disease (AD). In modeling this pathology, transgenic animals such as the APP23 strain, that expresses a mutant form of the amyloid precursor protein found in familial cases of AD, have been instrumental. In previous studies, we have shown that repeated treatments with ultrasound in a scanning mode (termed scanning ultrasound or SUS) were effective in removing Abeta and restoring memory functions, without the need for a therapeutic agent such as an Abeta antibody. Considering that age is the most important risk factor for AD, we extended this study in which the mice were only 12 months old at the time of treatment by assessing a cohort of 2 year-old mice. Interestingly, at this age, APP23 mice are characterized by cerebral amyloid angiopathy (CAA) and the presence of occasional microbleeds. We found that SUS in aged mice that have been exposed to four SUS sessions that were spread out over 8 weeks and analyzed 4 weeks later did not show evidence of increased CAA or microbleeds. Furthermore, amyloid was reduced as assessed by methoxy-XO4 fluorescence. In addition, plaque-associated microglia were more numerous in SUS treated mice. Together this adds to the notion that SUS may be a treatment modality for human neurodegenerative diseases. PMID- 29467615 TI - Decoding English Alphabet Letters Using EEG Phase Information. AB - Increasing evidence indicates that the phase pattern and power of the low frequency oscillations of brain electroencephalograms (EEG) contain significant information during the human cognition of sensory signals such as auditory and visual stimuli. Here, we investigate whether and how the letters of the alphabet can be directly decoded from EEG phase and power data. In addition, we investigate how different band oscillations contribute to the classification and determine the critical time periods. An English letter recognition task was assigned, and statistical analyses were conducted to decode the EEG signal corresponding to each letter visualized on a computer screen. We applied support vector machine (SVM) with gradient descent method to learn the potential features for classification. It was observed that the EEG phase signals have a higher decoding accuracy than the oscillation power information. Low-frequency theta and alpha oscillations have phase information with higher accuracy than do other bands. The decoding performance was best when the analysis period began from 180 to 380 ms after stimulus presentation, especially in the lateral occipital and posterior temporal scalp regions (PO7 and PO8). These results may provide a new approach for brain-computer interface techniques (BCI) and may deepen our understanding of EEG oscillations in cognition. PMID- 29467616 TI - Molecular Characterization of GABA-A Receptor Subunit Diversity within Major Peripheral Organs and Their Plasticity in Response to Early Life Psychosocial Stress. AB - Gamma aminobutyric acid (GABA) subtype A receptors (GABAARs) are integral membrane ion channels composed of five individual proteins or subunits. Up to 19 different GABAAR subunits (alpha1-6, beta1-3, gamma1-3, delta, epsilon, theta, pi, and rho1-3) have been identified, resulting in anatomically, physiologically, and pharmacologically distinct multiple receptor subtypes, and therefore GABA mediated inhibition, across the central nervous system (CNS). Additionally, GABAAR-modulating drugs are important tools in clinical medicine, although their use is limited by adverse effects. While significant advances have been made in terms of characterizing the GABAAR system within the brain, relatively less is known about the molecular phenotypes within the peripheral nervous system of major organ systems. This represents a potentially missed therapeutic opportunity in terms of utilizing or repurposing clinically available GABAAR drugs, as well as promising research compounds discarded due to their poor CNS penetrance, for the treatment of peripheral disorders. In addition, a broader understanding of the peripheral GABAAR subtype repertoires will contribute to the design of therapies which minimize peripheral side-effects when treating CNS disorders. We have recently provided a high resolution molecular and function characterization of the GABAARs within the enteric nervous system of the mouse colon. In this study, the aim was to determine the constituent GABAAR subunit expression profiles of the mouse bladder, heart, liver, kidney, lung, and stomach, using reverse transcription polymerase chain reaction and western blotting with brain as control. The data indicate that while some subunits are expressed widely across various organs (alpha3-5), others are restricted to individual organs (gamma2, only stomach). Furthermore, we demonstrate complex organ-specific developmental expression plasticity of the transporters which determine the chloride gradient within cells, and therefore whether GABAAR activation has a depolarizing or hyperpolarizing effect. Finally, we demonstrate that prior exposure to early life psychosocial stress induces significant changes in peripheral GABAAR subunit expression and chloride transporters, in an organ- and subunit-specific manner. Collectively, the data demonstrate the molecular diversity of the peripheral GABAAR system and how this changes dynamically in response to life experience. This provides a molecular platform for functional analyses of the GABA-GABAAR system in health, and in diseases affecting various peripheral organs. PMID- 29467617 TI - Quantitative Proteomics of Synaptosomal Fractions in a Rat Overexpressing Human DISC1 Gene Indicates Profound Synaptic Dysregulation in the Dorsal Striatum. AB - Disrupted-in-schizophrenia 1 (DISC1) is a key protein involved in behavioral processes and various mental disorders, including schizophrenia and major depression. A transgenic rat overexpressing non-mutant human DISC1, modeling aberrant proteostasis of the DISC1 protein, displays behavioral, biochemical and anatomical deficits consistent with aspects of mental disorders, including changes in the dorsal striatum, an anatomical region critical in the development of behavioral disorders. Herein, dorsal striatum of 10 transgenic DISC1 (tgDISC1) and 10 wild type (WT) littermate control rats was used for synaptosomal preparations and for performing liquid chromatography-tandem mass spectrometry (LC-MS)-based quantitative proteomics, using isobaric labeling (TMT10plex). Functional enrichment analysis was generated from proteins with level changes. The increase in DISC1 expression leads to changes in proteins and synaptic associated processes including membrane trafficking, ion transport, synaptic organization and neurodevelopment. Canonical pathway analysis assigned proteins with level changes to actin cytoskeleton, Galphaq, Rho family GTPase and Rho GDI, axonal guidance, ephrin receptor and dopamine-DARPP32 feedback in cAMP signaling. DISC1-regulated proteins proposed in the current study are also highly associated with neurodevelopmental and mental disorders. Bioinformatics analyses from the current study predicted that the following biological processes may be activated by overexpression of DISC1, i.e., regulation of cell quantities, neuronal and axonal extension and long term potentiation. Our findings demonstrate that the effects of overexpression of non-mutant DISC1 or its misassembly has profound consequences on protein networks essential for behavioral control. These results are also relevant for the interpretation of previous as well as for the design of future studies on DISC1. PMID- 29467618 TI - Reevaluation of FMR1 Hypermethylation Timing in Fragile X Syndrome. AB - Fragile X syndrome (FXS) is one of the most common heritable forms of cognitive impairment. It results from a fragile X mental retardation protein (FMRP) protein deficiency caused by a CGG repeat expansion in the 5'-UTR of the X-linked FMR1 gene. Whereas in most individuals the number of CGGs is steady and ranges between 5 and 44 units, in patients it becomes extensively unstable and expands to a length exceeding 200 repeats (full mutation). Interestingly, this disease is exclusively transmitted by mothers who carry a premutation allele (55-200 CGG repeats). When the CGGs reach the FM range, they trigger the spread of abnormal DNA methylation, which coincides with a switch from active to repressive histone modifications. This results in epigenetic gene silencing of FMR1 presumably by a multi-stage, developmentally regulated process. The timing of FMR1 hypermethylation and transcription silencing is still hotly debated. There is evidence that hypermethylation varies considerably between and within the tissues of patients as well as during fetal development, thus supporting the view that FMR1 silencing is a post-zygotic event that is developmentally structured. On the other hand, it may be established in the female germ line and transmitted to the fetus as an integral part of the mutation. This short review summarizes the data collected to date concerning the timing of FMR1 epigenetic gene silencing and reassess the evidence in favor of the theory that gene inactivation takes place by a developmentally regulated process around the 10th week of gestation. PMID- 29467619 TI - Cannabidiol Regulates Long Term Potentiation Following Status Epilepticus: Mediation by Calcium Stores and Serotonin. AB - Epilepsy is a devastating disease, with cognitive and emotional consequences that are not curable. In recent years, it became apparent that cannabinoids help patients to cope with epilepsy. We have studied the effects of cannabidiol (CBD) on the ability to produce long term potentiation (LTP) in stratum radiatum of CA1 region of the mouse hippocampus. Exposure to seizure-producing pilocarpine reduced the ability to generate LTP in the slice. Pre-exposure to CBD prevented this effect of pilocarpine. Furthermore, CBD caused a marked increase in ability to generate LTP, an effect that was blocked by calcium store antagonists as well as by a reduction in serotonin tone. Serotonin, possibly acting at a 5HT1A receptor, or fenfluramine (FFA), which causes release of serotonin from its native terminals, mimicked the effect of CBD. It is proposed that CBD enhances non-NMDA LTP in the slice by facilitating release of serotonin from terminals, consequently ameliorating the detrimental effects of pilocarpine. PMID- 29467620 TI - MiR-429 Regulated by Endothelial Monocyte Activating Polypeptide-II (EMAP-II) Influences Blood-Tumor Barrier Permeability by Inhibiting the Expressions of ZO 1, Occludin and Claudin-5. AB - The blood-tumor barrier (BTB) hinders delivery of chemotherapeutic drugs to tumors in the brain; previous studies have shown that the BTB can be selectively opened by endothelial monocyte activating polypeptide-II (EMAP-II), but the specific mechanism involved remains elusive. In this study, we found that microRNA-429 (miR-429) expression in glioma vascular endothelial cells (GECs) was far lower than in human brain microvascular endothelial cells (ECs). miR-429 had lower expression in GECs and glioma tissues compared to ECs or normal tissues of the brain. Furthermore, miR-429 had lower expression in high grade glioma (HGG) than in low grade glioma (LGG). In in vitro BTB models, we also found that EMAP II significantly increased BTB permeability, decreased expression of ZO-1, occludin and claudin-5 in GECs, in a time- and dose-dependent manner. EMAP-II greatly increased miR-429 expression in GECs of the BTB models in vitro. Overexpression of miR-429 in GECs significantly decreased the transepithelial electric resistance (TEER) values in BTB models, and led to enhanced horseradish peroxidase (HRP) flux. Overexpression of miR-429 in GECs significantly decreased the expression of tight junction (TJ)-associated proteins (ZO-1, occludin and claudin-5), and decreased the distribution continuity. Silencing of miR-429 in GECs increased the expression of TJ-associated proteins and the distribution continuity. The dual-luciferase reporter assay revealed that ZO-1 and occludin were target genes of miR-429, and we demonstrated that miR-429 overexpression markedly down-regulated protein expression of p70S6K, as well as its phosphorylation levels. The dual-luciferase reporter assay also showed that p70S6K was a target gene of miR-429; miR-429 overexpression down-regulated expression and phosphorylation levels of p70S6K, and also decreased phosphorylation levels of S6 and increased BTB permeability. Conversely, silencing of miR-429 increased the expression and phosphorylation levels of p70S6K, and increased phosphorylation levels of S6, while decreasing BTB permeability. In conclusion, the results indicated that EMAP-II caused an increase in miR-429 expression that directly targeted TJ-associated proteins, which were negatively regulated; on the other hand, miR-429 down-regulated the expression of TJ-associated proteins by targeting p70S6K, also negatively regulated. As a result, the BTB permeability increased. PMID- 29467621 TI - Immunosignals of Oligodendrocyte Markers and Myelin-Associated Proteins Are Critically Affected after Experimental Stroke in Wild-Type and Alzheimer Modeling Mice of Different Ages. AB - Because stroke therapies are still limited and patients are often concerned by long-term sequelae with significant impairment of daily living, elaborated neuroprotective strategies are needed. During the last decades, research substantially improved the knowledge on cellular pathologies responsible for stroke-related tissue damage. In this context, the neurovascular unit (NVU) concept has been established, summarizing the affections of neurons, associated astrocytes and the vasculature. Although oligodendrocytes were already identified to play a major role in other brain pathologies, their role during stroke evolution and long-lasting tissue damage is poorly understood. This study aims to explore oligodendrocyte structures, i.e., oligodendrocytes and their myelin associated proteins, after experimental focal cerebral ischemia. For translational issues, different ages and genotypes including an Alzheimer-like background were considered to mimic potential co-morbidities. Three- and 12-month old wild-type and triple-transgenic mice were subjected to unilateral middle cerebral artery occlusion. Immunofluorescence labeling was performed on forebrain tissues affected by 24 h of ischemia to visualize the oligodendrocyte-specific protein (OSP), the myelin basic protein (MBP), and the neuron-glia antigen 2 (NG2) with reference to the ischemic lesion. Subsequent analyses concomitantly detected the vasculature and the 2', 3'-cyclic nucleotide-3'-phosphodiesterase (CNPase) to consider the NVU concept and to explore the functional relevance of histochemical data on applied oligodendrocyte markers. While the immunosignal of NG2 was found to be nearly absent 24 h after ischemia onset, enhanced immunoreactivities for OSP and especially MBP were observed in close regional association to the vasculature. Added quantitative analyses based on inter hemispheric differences of MBP-immunoreactivity revealed a shell-like pattern with a significant increase directly in the ischemic core, followed by a gradual decline toward the striatum, the ischemic border zone and the lateral neocortex. This observation was consistent in subsequent analyses on the potential impact of age and genetic background. Furthermore, immunoreactivities for CNPase, MBP, and OSP were found to be simultaneously enhanced. In conclusion, this study provides evidence for a critical role of oligodendrocyte structures in the early phase after experimental stroke, strengthening their involvement in the ischemia affected NVU. Consequently, oligodendrocytes and their myelin-associated proteins may qualify as potential targets for neuroprotective and regenerative approaches in stroke. PMID- 29467623 TI - eIF4E Phosphorylation Influences Bdnf mRNA Translation in Mouse Dorsal Root Ganglion Neurons. AB - Plasticity in dorsal root ganglion (DRG) neurons that promotes pain requires activity-dependent mRNA translation. Protein synthesis inhibitors block the ability of many pain-promoting molecules to enhance excitability in DRG neurons and attenuate behavioral signs of pain plasticity. In line with this, we have recently shown that phosphorylation of the 5' cap-binding protein, eIF4E, plays a pivotal role in plasticity of DRG nociceptors in models of hyperalgesic priming. However, mRNA targets of eIF4E phosphorylation have not been elucidated in the DRG. Brain-derived neurotrophic factor (BDNF) signaling from nociceptors in the DRG to spinal dorsal horn neurons is an important mediator of hyperalgesic priming. Regulatory mechanisms that promote pain plasticity via controlling BDNF expression that is involved in promoting pain plasticity have not been identified. We show that phosphorylation of eIF4E is paramount for Bdnf mRNA translation in the DRG. Bdnf mRNA translation is reduced in mice lacking eIF4E phosphorylation (eIF4ES209A ) and pro-nociceptive factors fail to increase BDNF protein levels in the DRGs of these mice despite robust upregulation of Bdnf-201 mRNA levels. Importantly, bypassing the DRG by giving intrathecal injection of BDNF in eIF4ES209A mice creates a strong hyperalgesic priming response that is normally absent or reduced in these mice. We conclude that eIF4E phosphorylation mediated translational control of BDNF expression is a key mechanism for nociceptor plasticity leading to hyperalgesic priming. PMID- 29467624 TI - Procedure for the Isolation of Endothelial Cells from Human Cerebral Arteriovenous Malformation (cAVM) Tissues. AB - In this study, we successfully established a stable method for the isolation of endothelial cells (ECs) from human cerebral arteriovenous malformation (cAVM) tissues. Despite human cAVM tissues having a minor population of ECs, they play an important role in the manifestation and development of cAVM as well as in hemorrhagic stroke and thrombogenesis. To characterize and understand the biology of ECs in human cAVM (cAVM-ECs), methods for the isolation and purification of these cells are necessary. We have developed this method to reliably obtain pure populations of ECs from cAVMs. To obtain pure cell populations, cAVM tissues were mechanically and enzymatically digested and the resulting single cAVM-ECs suspensions were then labeled with antibodies of specific cell antigens and selected by flow cytometry. Purified ECs were detected using specific makers of ECs by immunostaining and used to study different cellular mechanisms. Compared to the different methods of isolating ECs from tissues, we could isolate ECs from cAVMs confidently, and the numbers of cAVM-ECs harvested were almost similar to the amounts present in vessel components. In addition to optimizing the protocol for isolation of ECs from human cAVM tissues, the protocol could also be applied to isolate ECs from other human neurovascular-diseased tissues. Depending on the tissues, the whole procedure could be completed in about 20 days. PMID- 29467622 TI - Revisiting the Role of Clathrin-Mediated Endoytosis in Synaptic Vesicle Recycling. AB - Without robust mechanisms to efficiently form new synaptic vesicles (SVs), the tens to hundreds of SVs typically present at the neuronal synapse would be rapidly used up, even at modest levels of neuronal activity. SV recycling is thus critical for synaptic physiology and proper function of sensory and nervous systems. Yet, more than four decades after it was originally proposed that the SVs are formed and recycled locally at the presynaptic terminals, the mechanisms of endocytic processes at the synapse are heavily debated. Clathrin-mediated endocytosis, a type of endocytosis that capitalizes on the clathrin coat, a number of adaptor and accessory proteins, and the GTPase dynamin, is well understood, while the contributions of clathrin-independent fast endocytosis, kiss-and-run, bulk endocytosis and ultrafast endocytosis are still being evaluated. This review article revisits and summarizes the current knowledge on the SV reformation with a focus on clathrin-mediated endocytosis, and it discusses the modes of SV formation from endosome-like structures at the synapse. Given the importance of this topic, future advances in this active field are expected to contribute to better comprehension of neurotransmission, and to have general implications for neuroscience and medicine. PMID- 29467626 TI - The Fly Sensitizing Pigment Enhances UV Spectral Sensitivity While Preventing Polarization-Induced Artifacts. AB - Microvillar photoreceptors are intrinsically capable of detecting the orientation of e-vector of linearly polarized light. They provide most invertebrates with an additional sensory channel to detect important features of their visual environment. However, polarization sensitivity (PS) of photoreceptors may lead to the detection of polarization-induced false colors and intensity contrasts. Most insect photoreceptors are thus adapted to have minimal PS. Flies have twisted rhabdomeres with microvilli rotated along the length of the ommatidia to reduce PS. The additional UV-absorbing sensitizing pigment on their opsin minimizes PS in the ultraviolet. We recorded voltage from Drosophila photoreceptors R1-6 to measure the spectral dependence of PS and found that PS in the UV is invariably negligible but can be substantial above 400 nm. Using modeling, we demonstrate that in R1-6 without the sensitizing pigment, PS in the UV (PS UV ) would exceed PS in the visible part of the spectrum (PS VIS ) by a factor PS UV /PS VIS = 1.2 1.8, as lower absorption of Rh1 rhodopsin reduces self-screening. We use polarimetric imaging of objects relevant to fly polarization vision to show that their degree of polarization outdoors is highest in the short-wavelength part of the spectrum. Thus, under natural illumination, the sensitizing pigment in R1-6 renders even those cells with high PS in the visible part unsuitable for proper polarization vision. We assume that fly ventral polarization vision can be mediated by R7 alone, with R1-6 serving as an unpolarized reference channel. PMID- 29467625 TI - Effect of Vitamin D in HN9.10e Embryonic Hippocampal Cells and in Hippocampus from MPTP-Induced Parkinson's Disease Mouse Model. AB - It has long been proven that neurogenesis continues in the adult brains of mammals in the dentatus gyrus of the hippocampus due to the presence of neural stem cells. Although a large number of studies have been carried out to highlight the localization of vitamin D receptor in hippocampus, the expression of vitamin D receptor in neurogenic dentatus gyrus of hippocampus in Parkinson's disease (PD) and the molecular mechanisms triggered by vitamin D underlying the production of differentiated neurons from embryonic cells remain unknown. Thus, we performed a preclinical in vivo study by inducing PD in mice with MPTP and showed a reduction of glial fibrillary acidic protein (GFAP) and vitamin D receptor in the dentatus gyrus of hippocampus. Then, we performed an in vitro study by inducing embryonic hippocampal cell differentiation with vitamin D. Interestingly, vitamin D stimulates the expression of its receptor. Vitamin D receptor is a transcription factor that probably is responsible for the upregulation of microtubule associated protein 2 and neurofilament heavy polypeptide genes. The latter increases heavy neurofilament protein expression, essential for neurofilament growth. Notably N-cadherin, implicated in activity for dendritic outgrowth, is upregulated by vitamin D. PMID- 29467628 TI - Anatomical Evidence for a Direct Projection from Purkinje Cells in the Mouse Cerebellar Vermis to Medial Parabrachial Nucleus. AB - Cerebellar malformations cause changes to the sleep-wake cycle, resulting in sleep disturbance. However, it is unclear how the cerebellum contributes to the sleep-wake cycle. To examine the neural connections between the cerebellum and the nuclei involved in the sleep-wake cycle, we investigated the axonal projections of Purkinje cells in the mouse posterior vermis by using an adeno associated virus (AAV) vector (serotype rh10) as an anterograde tracer. When an AAV vector expressing humanized renilla green fluorescent protein was injected into the cerebellar lobule IX, hrGFP and synaptophysin double-positive axonal terminals were observed in the region of medial parabrachial nucleus (MPB). The MPB is involved in the phase transition from rapid eye movement (REM) sleep to Non-REM sleep and vice versa, and the cardiovascular and respiratory responses. The hrGFP-positive axons from lobule IX went through the ventral spinocerebellar tract and finally reached the MPB. By contrast, when the AAV vector was injected into cerebellar lobule VI, no hrGFP-positive axons were observed in the MPB. To examine neurons projecting to the MPB, we unilaterally injected Fast Blue and AAV vector (retrograde serotype, rAAV2-retro) as retrograde tracers into the MPB. The cerebellar Purkinje cells in lobules VIII-X on the ipsilateral side of the Fast Blue-injected MPB were retrogradely labeled by Fast Blue and AAV vector (retrograde serotype), but no retrograde-labeled Purkinje cells were observed in lobules VI-VII and the cerebellar hemispheres. These results indicated that Purkinje cells in lobules VIII-X directly project their axons to the ipsilateral MPB but not lobules VI-VII. The direct connection between lobules VIII-X and the MPB suggests that the cerebellum participates in the neural network controlling the sleep-wake cycle, and cardiovascular and respiratory responses, by modulating the physiological function of the MPB. PMID- 29467627 TI - Basal Ganglia Neuromodulation Over Multiple Temporal and Structural Scales Simulations of Direct Pathway MSNs Investigate the Fast Onset of Dopaminergic Effects and Predict the Role of Kv4.2. AB - The basal ganglia are involved in the motivational and habitual control of motor and cognitive behaviors. Striatum, the largest basal ganglia input stage, integrates cortical and thalamic inputs in functionally segregated cortico-basal ganglia-thalamic loops, and in addition the basal ganglia output nuclei control targets in the brainstem. Striatal function depends on the balance between the direct pathway medium spiny neurons (D1-MSNs) that express D1 dopamine receptors and the indirect pathway MSNs that express D2 dopamine receptors. The striatal microstructure is also divided into striosomes and matrix compartments, based on the differential expression of several proteins. Dopaminergic afferents from the midbrain and local cholinergic interneurons play crucial roles for basal ganglia function, and striatal signaling via the striosomes in turn regulates the midbrain dopaminergic system directly and via the lateral habenula. Consequently, abnormal functions of the basal ganglia neuromodulatory system underlie many neurological and psychiatric disorders. Neuromodulation acts on multiple structural levels, ranging from the subcellular level to behavior, both in health and disease. For example, neuromodulation affects membrane excitability and controls synaptic plasticity and thus learning in the basal ganglia. However, it is not clear on what time scales these different effects are implemented. Phosphorylation of ion channels and the resulting membrane effects are typically studied over minutes while it has been shown that neuromodulation can affect behavior within a few hundred milliseconds. So how do these seemingly contradictory effects fit together? Here we first briefly review neuromodulation of the basal ganglia, with a focus on dopamine. We furthermore use biophysically detailed multi-compartmental models to integrate experimental data regarding dopaminergic effects on individual membrane conductances with the aim to explain the resulting cellular level dopaminergic effects. In particular we predict dopaminergic effects on Kv4.2 in D1-MSNs. Finally, we also explore dynamical aspects of the onset of neuromodulation effects in multi-scale computational models combining biochemical signaling cascades and multi-compartmental neuron models. PMID- 29467629 TI - Orientation-Selective Retinal Circuits in Vertebrates. AB - Visual information is already processed in the retina before it is transmitted to higher visual centers in the brain. This includes the extraction of salient features from visual scenes, such as motion directionality or contrast, through neurons belonging to distinct neural circuits. Some retinal neurons are tuned to the orientation of elongated visual stimuli. Such 'orientation-selective' neurons are present in the retinae of most, if not all, vertebrate species analyzed to date, with species-specific differences in frequency and degree of tuning. In some cases, orientation-selective neurons have very stereotyped functional and morphological properties suggesting that they represent distinct cell types. In this review, we describe the retinal cell types underlying orientation selectivity found in various vertebrate species, and highlight their commonalities and differences. In addition, we discuss recent studies that revealed the cellular, synaptic and circuit mechanisms at the basis of retinal orientation selectivity. Finally, we outline the significance of these findings in shaping our current understanding of how this fundamental neural computation is implemented in the visual systems of vertebrates. PMID- 29467630 TI - Neural, Cellular and Molecular Mechanisms of Active Forgetting. AB - The neurobiology of memory formation attracts much attention in the last five decades. Conversely, the rules that govern and the mechanisms underlying forgetting are less understood. In addition to retroactive interference, retrieval-induced forgetting and passive decay of time, it has been recently demonstrated that the nervous system has a diversity of active and inherent processes involved in forgetting. In Drosophila, some operate mainly at an early stage of memory formation and involves dopamine (DA) neurons, specific postsynaptic DA receptor subtypes, Rac1 activation and induces rapid active forgetting. In mammals, others regulate forgetting and persistence of seemingly consolidated memories and implicate the activity of DA receptor subtypes and AMPA receptors in the hippocampus (HP) and related structures to activate parallel signaling pathways controlling active time-dependent forgetting. Most of them may involve plastic changes in synaptic and extrasynaptic receptors including specific removal of GluA2 AMPA receptors. Forgetting at longer timescales might also include changes in adult neurogenesis in the dentate gyrus (DG) of the HP. Therefore, based on relevance or value considerations neuronal circuits may regulate in a time-dependent manner what is formed, stored, and maintained and what is forgotten. PMID- 29467631 TI - Neural Temporal Dynamics of Social Exclusion Elicited by Averted Gaze: An Event Related Potentials Study. AB - Eye gaze plays a fundamental role in social communication. The averted eye gaze during social interaction, as the most common form of silent treatment, conveys a signal of social exclusion. In the present study, we examined the time course of brain response to social exclusion by using a modified version of Eye-gaze paradigm. The event-related potentials (ERPs) data and the subjective rating data showed that the frontocentral P200 was positively correlated with negative mood of excluded events, whereas, the centroparietal late positive potential (LPP) was positively correlated with the perceived ostracism intensity. Both the P200 and LPP were more positive-going for excluded events than for included events. These findings suggest that brain responses sensitive to social exclusion can be divided into the early affective processing stage, linking to the early pre cognitive warning system; and the late higher-order processes stage, demanding attentional resources for elaborate stimuli evaluation and categorization generally not under specific situation. PMID- 29467632 TI - Dissociating Explicit and Implicit Timing in Parkinson's Disease Patients: Evidence from Bisection and Foreperiod Tasks. AB - A consistent body of literature reported that Parkinson's disease (PD) is marked by severe deficits in temporal processing. However, the exact nature of timing problems in PD patients is still elusive. In particular, what remains unclear is whether the temporal dysfunction observed in PD patients regards explicit and/or implicit timing. Explicit timing tasks require participants to attend to the duration of the stimulus, whereas in implicit timing tasks no explicit instruction to process time is received but time still affects performance. In the present study, we investigated temporal ability in PD by comparing 20 PD participants and 20 control participants in both explicit and implicit timing tasks. Specifically, we used a time bisection task to investigate explicit timing and a foreperiod task for implicit timing. Moreover, this is the first study investigating sequential effects in PD participants. Results showed preserved temporal ability in PD participants in the implicit timing task only (i.e., normal foreperiod and sequential effects). By contrast, PD participants failed in the explicit timing task as they displayed shorter perceived durations and higher variability compared to controls. Overall, the dissociation reported here supports the idea that timing can be differentiated according to whether it is explicitly or implicitly processed, and that PD participants are selectively impaired in the explicit processing of time. PMID- 29467633 TI - Closed-Loop Targeted Memory Reactivation during Sleep Improves Spatial Navigation. AB - Sounds associated with newly learned information that are replayed during non rapid eye movement (NREM) sleep can improve recall in simple tasks. The mechanism for this improvement is presumed to be reactivation of the newly learned memory during sleep when consolidation takes place. We have developed an EEG-based closed-loop system to precisely deliver sensory stimulation at the time of down state to up-state transitions during NREM sleep. Here, we demonstrate that applying this technology to participants performing a realistic navigation task in virtual reality results in a significant improvement in navigation efficiency after sleep that is accompanied by increases in the spectral power especially in the fast (12-15 Hz) sleep spindle band. Our results show promise for the application of sleep-based interventions to drive improvement in real-world tasks. PMID- 29467635 TI - Oscillatory Brain Responses Reflect Anticipation during Comprehension of Speech Acts in Spoken Dialog. AB - Everyday conversation requires listeners to quickly recognize verbal actions, so called speech acts, from the underspecified linguistic code and prepare a relevant response within the tight time constraints of turn-taking. The goal of this study was to determine the time-course of speech act recognition by investigating oscillatory EEG activity during comprehension of spoken dialog. Participants listened to short, spoken dialogs with target utterances that delivered three distinct speech acts (Answers, Declinations, Pre-offers). The targets were identical across conditions at lexico-syntactic and phonetic/prosodic levels but differed in the pragmatic interpretation of the speech act performed. Speech act comprehension was associated with reduced power in the alpha/beta bands just prior to Declination speech acts, relative to Answers and Pre-offers. In addition, we observed reduced power in the theta band during the beginning of Declinations, relative to Answers. Based on the role of alpha and beta desynchronization in anticipatory processes, the results are taken to indicate that anticipation plays a role in speech act recognition. Anticipation of speech acts could be critical for efficient turn-taking, allowing interactants to quickly recognize speech acts and respond within the tight time frame characteristic of conversation. The results show that anticipatory processes can be triggered by the characteristics of the interaction, including the speech act type. PMID- 29467636 TI - Increased Posterior Insula-Sensorimotor Connectivity Is Associated with Cognitive Function in Healthy Participants with Sleep Complaints. AB - Insomnia is characterized by sensory hypersensitivity and cognitive impairments. Recent work has identified the insula as a central brain region involved in both bottom-up gating of sensory information and top-down cognitive control. However, the specific relationships between insular subregion connectivity and emotional and cognitive functions remain unclear. In this study, resting-state functional magnetic resonance imaging data were obtained from 25 healthy participants with sleep complaints (HPS) and 25 age-, gender- and educational level-matched healthy participants without insomnia complaints (HP). We performed insular subregion (ventral anterior, dorsal anterior and posterior) functional connectivity (FC) analyses, and cognitive function was measured with several validated test procedures (e.g., the Wisconsin Card Sorting Test [WCST], Continuous Performance Test [CPT] and Trail making Test [TMT]). There were no significant differences between the two groups for WCST, CPT and TMT scores. The HPS group showed enhanced connectivity from the right posterior insula (R-PI) to the left postcentral gyrus (L-postCG) compared to HP group. WCST random errors (RE), sleep disturbance scores and HAMA scores correlated with this connectivity measurement in both HP and HPS groups. Our results provide direct evidence that the posterior insula (PI) synchronizes with sensorimotor areas to detect homeostatic changes and suggest that alteration of the latter is related to executive dysfunction in subjects with insomnia. PMID- 29467634 TI - EEG-Informed fMRI: A Review of Data Analysis Methods. AB - The simultaneous acquisition of electroencephalography (EEG) with functional magnetic resonance imaging (fMRI) is a very promising non-invasive technique for the study of human brain function. Despite continuous improvements, it remains a challenging technique, and a standard methodology for data analysis is yet to be established. Here we review the methodologies that are currently available to address the challenges at each step of the data analysis pipeline. We start by surveying methods for pre-processing both EEG and fMRI data. On the EEG side, we focus on the correction for several MR-induced artifacts, particularly the gradient and pulse artifacts, as well as other sources of EEG artifacts. On the fMRI side, we consider image artifacts induced by the presence of EEG hardware inside the MR scanner, and the contamination of the fMRI signal by physiological noise of non-neuronal origin, including a review of several approaches to model and remove it. We then provide an overview of the approaches specifically employed for the integration of EEG and fMRI when using EEG to predict the blood oxygenation level dependent (BOLD) fMRI signal, the so-called EEG-informed fMRI integration strategy, the most commonly used strategy in EEG-fMRI research. Finally, we systematically review methods used for the extraction of EEG features reflecting neuronal phenomena of interest. PMID- 29467638 TI - A Reinforcement-Based Learning Paradigm Increases Anatomical Learning and Retention-A Neuroeducation Study. AB - In anatomy education, a key hurdle to engaging in higher-level discussion in the classroom is recognizing and understanding the extensive terminology used to identify and describe anatomical structures. Given the time-limited classroom environment, seeking methods to impart this foundational knowledge to students in an efficient manner is essential. Just-in-Time Teaching (JiTT) methods incorporate pre-class exercises (typically online) meant to establish foundational knowledge in novice learners so subsequent instructor-led sessions can focus on deeper, more complex concepts. Determining how best do we design and assess pre-class exercises requires a detailed examination of learning and retention in an applied educational context. Here we used electroencephalography (EEG) as a quantitative dependent variable to track learning and examine the efficacy of JiTT activities to teach anatomy. Specifically, we examined changes in the amplitude of the N250 and reward positivity event-related brain potential (ERP) components alongside behavioral performance as novice students participated in a series of computerized reinforcement-based learning modules to teach neuroanatomical structures. We found that as students learned to identify anatomical structures, the amplitude of the N250 increased and reward positivity amplitude decreased in response to positive feedback. Both on a retention and transfer exercise when learners successfully remembered and translated their knowledge to novel images, the amplitude of the reward positivity remained decreased compared to early learning. Our findings suggest ERPs can be used as a tool to track learning, retention, and transfer of knowledge and that employing the reinforcement learning paradigm is an effective educational approach for developing anatomical expertise. PMID- 29467637 TI - Anterior Temporal Lobe Morphometry Predicts Categorization Ability. AB - Categorization is the mental operation by which the brain classifies objects and events. It is classically assessed using semantic and non-semantic matching or sorting tasks. These tasks show a high variability in performance across healthy controls and the cerebral bases supporting this variability remain unknown. In this study we performed a voxel-based morphometry study to explore the relationships between semantic and shape categorization tasks and brain morphometric differences in 50 controls. We found significant correlation between categorization performance and the volume of the gray matter in the right anterior middle and inferior temporal gyri. Semantic categorization tasks were associated with more rostral temporal regions than shape categorization tasks. A significant relationship was also shown between white matter volume in the right temporal lobe and performance in the semantic tasks. Tractography revealed that this white matter region involved several projection and association fibers, including the arcuate fasciculus, inferior fronto-occipital fasciculus, uncinate fasciculus, and inferior longitudinal fasciculus. These results suggest that categorization abilities are supported by the anterior portion of the right temporal lobe and its interaction with other areas.

PMID- 29467640 TI - Alterations of Resting-State Static and Dynamic Functional Connectivity of the Dorsolateral Prefrontal Cortex in Subjects with Internet Gaming Disorder. AB - Internet gaming disorder (IGD), a major behavior disorder, has gained increasing attention. Recent studies indicate altered resting-state static functional connectivity (FC) of the dorsolateral prefrontal cortex (DLPFC) in subjects with IGD. Whereas static FC often provides information on functional changes in subjects with IGD, investigations of temporal changes in FC between the DLPFC and the other brain regions may shed light on the dynamic characteristics of brain function associated with IGD. Thirty subjects with IGD and 30 healthy controls (HCs) matched for age, gender and education status were recruited. Using the bilateral DLPFC as seeds, static FC and dynamic FC maps were calculated and compared between groups. Correlations between alterations in static FC and dynamic FC and clinical variables were also investigated within the IGD group. The IGD group showed significantly lower static FC between the right DLPFC and the left rolandic operculum while higher static FC between the right DLPFC and the left pars triangularis when compared to HCs. The IGD group also had significantly decreased dynamic FC between the right DLPFC and the left insula, right putamen and left precentral gyrus, and increased dynamic FC in the left precuneus. Moreover, the dynamic FC between the right DLPFC and the left insula was negatively correlated with the severity of IGD. Dynamic FC can be used as a powerful supplement to static FC, helping us obtain a more comprehensive understanding of large-scale brain network activity in IGD and put forward new ideas for behavioral intervention therapy for it. PMID- 29467641 TI - Propensity for Bistability of Bursting and Silence in the Leech Heart Interneuron. AB - The coexistence of neuronal activity regimes has been reported under normal and pathological conditions. Such multistability could enhance the flexibility of the nervous system and has many implications for motor control, memory, and decision making. Multistability is commonly promoted by neuromodulation targeting specific membrane ionic currents. Here, we investigated how modulation of different ionic currents could affect the neuronal propensity for bistability. We considered a leech heart interneuron model. It exhibits bistability of bursting and silence in a narrow range of the leak current parameters, conductance (gleak ) and reversal potential (Eleak ). We assessed the propensity for bistability of the model by using bifurcation diagrams. On the diagram (gleak , Eleak ), we mapped bursting and silent regimes. For the canonical value of Eleak we determined the range of gleak which supported the bistability. We use this range as an index of propensity for bistability. We investigated how this index was affected by alterations of ionic currents. We systematically changed their conductances, one at a time, and built corresponding bifurcation diagrams in parameter planes of the maximal conductance of a given current and the leak conductance. We found that conductance of only one current substantially affected the index of propensity; the increase of the maximal conductance of the hyperpolarization activated cationic current increased the propensity index. The second conductance with the strongest effect was the conductance of the low-threshold fast Ca2+ current; its reduction increased the propensity index although the effect was about two times smaller in magnitude. Analyzing the model with both changes applied simultaneously, we found that the diagram (gleak , Eleak ) showed a progressively expanded area of bistability of bursting and silence. PMID- 29467642 TI - Subcritical Hopf Bifurcation and Stochastic Resonance of Electrical Activities in Neuron under Electromagnetic Induction. AB - The FitzHugh-Nagumo model is improved to consider the effect of the electromagnetic induction on single neuron. On the basis of investigating the Hopf bifurcation behavior of the improved model, stochastic resonance in the stochastic version is captured near the bifurcation point. It is revealed that a weak harmonic oscillation in the electromagnetic disturbance can be amplified through stochastic resonance, and it is the cooperative effect of random transition between the resting state and the large amplitude oscillating state that results in the resonant phenomenon. Using the noise dependence of the mean of interburst intervals, we essentially suggest a biologically feasible clue for detecting weak signal by means of neuron model with subcritical Hopf bifurcation. These observations should be helpful in understanding the influence of the magnetic field to neural electrical activity. PMID- 29467643 TI - Simultaneous Estimation of Low- and High-Order Functional Connectivity for Identifying Mild Cognitive Impairment. AB - Functional connectivity (FC) network has been becoming an increasingly useful tool for understanding the cerebral working mechanism and mining sensitive biomarkers for neural/mental disease diagnosis. Currently, Pearson's Correlation (PC) is the simplest and most commonly used scheme in FC estimation. Despite its empirical effectiveness, PC only encodes the low-order (i.e., second-order) statistics by calculating the pairwise correlations between network nodes (brain regions), which fails to capture the high-order information involved in FC (e.g., the correlations among different edges in a network). To address this issue, we propose a novel FC estimation method based on Matrix Variate Normal Distribution (MVND), which can capture both low- and high-order correlations simultaneously with a clear mathematical interpretability. Specifically, we first generate a set of BOLD subseries by the sliding window scheme, and for each subseries we construct a temporal FC network by PC. Then, we employ the constructed FC networks as samples to estimate the final low- and high-order FC networks by maximizing the likelihood of MVND. To illustrate the effectiveness of the proposed method, we conduct experiments to identify subjects with Mild Cognitive Impairment (MCI) from Normal Controls (NCs). Experimental results show that the fusion of low- and high-order FCs can generally help to improve the final classification performance, even though the high-order FC may contain less discriminative information than its low-order counterpart. Importantly, the proposed method for simultaneous estimation of low- and high-order FCs can achieve better classification performance than the two baseline methods, i.e., the original PC method and a recent high-order FC estimation method.

AB - Alzheimer's disease (AD) is a form of dementia and the most common progressive neurodegenerative disease (ND). The targeting of amyloid-beta (Abeta) aggregation is one of the most widely used strategies to manage AD, and efforts are being made globally to develop peptide-based compounds for the early diagnosis and treatment of AD. Here, we briefly discuss the use of peptide-based compounds for the early diagnosis and treatment of AD and the use of peptide-based inhibitors targeting various Abeta aggregation checkpoints. In addition, we briefly discuss recent applications of peptide-based inhibitors against various AD targets including amyloid beta, beta-site amyloid precursor protein cleaving enzyme 1 (BACE1), Glyceraldehyde-3-phosphate dehydrogenase (GAPDH), tyrosine phosphatase (TP) and potassium channel KV1.3. PMID- 29467645 TI - Plasma Exosomal miRNA-122-5p and miR-300-3p as Potential Markers for Transient Ischaemic Attack in Rats. AB - Background: Differentiation of transient ischaemic attack (TIA) from ischaemic stroke within the thrombolysis time window is difficult. Although TIA may be diagnosed within this window, the latest imaging technologies are complex and costly. Serum markers, which are non-invasive, rapid and economic, are used for diagnosis and prognosis of various diseases. Exosome-derived miRNA markers for TIA are unknown. Methods: We examined focal brain ischaemia produced by occlusion of the middle cerebral artery (MCAo) for 5 min, 10 min, and 2 h in rats. Exosomal miRNAs with consistent trends in cerebrospinal fluid (CSF) and plasma were identified by deep sequencing and quantitative real-time polymerase chain reaction (qRT-PCR). The areas under the curve (AUC) of the receiver operating characteristic (ROC) curve were used to evaluate the diagnostic accuracy of these miRNAs for TIA in rats. Results: Rno-miR-122-5p and rno-miR-300-3p were selected. Plasma exosomal rno-miR-122-5p was significantly downregulated in 10 min ischaemic rats compared with control and 5 min plasma. Plasma exosomal rno-miR 300-3p was significantly upregulated in 5 min ischaemic rats compared with control, 10 min and 2 h rats. Plasma and CSF levels of these miRNAs were correlated. ROC analysis showed high AUC values for rno-miR-122-5p (0.960) and rno-miR-300-3p (0.970) in the 10 and 5 min rats, respectively, compared with controls. Conclusions: Plasma exosomal rno-miR-122-5p and rno-miR-300-3p may be blood-based TIA biomarkers. PMID- 29467647 TI - Identification of a Novel Hemizygous SQSTM1 Nonsense Mutation in Atypical Behavioral Variant Frontotemporal Dementia. AB - Frontotemporal dementia includes a large spectrum of neurodegenerative disorders. SQSTM1, coding for p62 protein, plays a vital role in the pathogenesis of FTD. Here, we report a case of a female patient with SQSTM1 mutation S224X, who was 59 years old when she initially exhibited memory decline, mild personality changes, and subtle atrophy of frontal/temporal lobes in magnetic resonance imaging (MRI). Genetic testing revealed a nonsense mutation of the SQSTM1 gene (S224X), resulting in premature termination of protein synthesis and a predicted truncated protein 217 amino acids shorter than the normal protein. Moreover, neither intact nor truncated SQSTM1 proteins was detectable in SQSTM1 S224X mutant overexpressing HEK-293T cells. We assayed for SQSTM1 cDNA in samples from the patient's peripheral leucocytes, and did not detect its mutation. The test of quantitative PCR showed significant decreased level of SQSTM1 mRNA from peripheral leucocytes of the patient compared to five dementia controls. Our results identify a novel pathogenic SQSTM1 S224X mutation in an atypical FTD patient accompanied with loss of SQSTM1/p62 protein expression probably due to SQSTM1 gene haploinsufficiency. PMID- 29467646 TI - Age-Dependent Modulations of Resting State Connectivity Following Motor Practice. AB - Recent work in young adults has demonstrated that motor learning can modulate resting state functional connectivity. However, evidence for older adults is scarce. Here, we investigated whether learning a bimanual tracking task modulates resting state functional connectivity of both inter- and intra-hemispheric regions differentially in young and older individuals, and whether this has behavioral relevance. Both age groups learned a set of complex bimanual tracking task variants over a 2-week training period. Resting-state and task-related functional magnetic resonance imaging scans were collected before and after training. Our analyses revealed that both young and older adults reached considerable performance gains. Older adults even obtained larger training induced improvements relative to baseline, but their overall performance levels were lower than in young adults. Short-term practice resulted in a modulation of resting state functional connectivity, leading to connectivity increases in young adults, but connectivity decreases in older adults. This pattern of age differences occurred for both inter- and intra-hemispheric connections related to the motor network. Additionally, long-term training-induced increases were observed in intra-hemispheric connectivity in the right hemisphere across both age groups. Overall, at the individual level, the long-term changes in inter hemispheric connectivity correlated with training-induced motor improvement. Our findings confirm that short-term task practice shapes spontaneous brain activity differentially in young and older individuals. Importantly, the association between changes in resting state functional connectivity and improvements in motor performance at the individual level may be indicative of how training shapes the short-term functional reorganization of the resting state motor network for improvement of behavioral performance. PMID- 29467649 TI - Tolerance and Tachyphylaxis to Head Twitches Induced by the 5-HT2A Agonist 25CN NBOH in Mice. AB - The serotonin (5-HT) 2A receptor is the primary molecular target of serotonergic hallucinogens, which trigger large-scale perturbations of the cortex. Our understanding of how 5-HT2A activation may cause the effects of hallucinogens has been hampered by the receptor unselectivity of most of the drugs of this class. Here we used 25CN-NBOH (N-(2-hydroxybenzyl)-2,5-dimethoxy-4 cyanophenylethylamine), a newly developed selective 5-HT2A agonist, and tested it with regard to the head-twitch-response (HTR) model of 5-HT2A activity and effects on locomotion. 25CN-NBOH evoked HTRs with an inverted u-shape-like dose response curve and highest efficacy at 1.5 mg/kg, i.p. HTR occurrence peaked within 5 min after agonist injection, and exponentially decreased to half-maximal frequency at ~11 min. Thorough habituation to the experimental procedures (including handling, saline injection, and exposure to the observational boxes 1 day before the experiment) facilitated the animals' response to 25CN-NBOH. 25CN NBOH (1.5 mg/kg, i.p.) induced HTRs were blocked by the 5-HT2A antagonist ketanserin (0.75 mg/kg, 30 min pre), but not by the 5-HT2C antagonist SB-242084 (0.5 mg/kg, i.p., 30 min pre). SB-242084 instead slightly increased the number of HTRs occurring at a 3.0-mg/kg dose of the agonist. Apart from HTR induction, 25CN NBOH also modestly increased locomotor activity of the mice. Repeated once-per day injections (1.5 mg/kg, i.p.) led to reduced occurrence of 25CN-NBOH induced HTRs. This intermediate tolerance was augmented when a second (higher) dose of the drug (3.0 mg/kg) was interspersed. Short-interval tolerance (i.e., tachyphylaxis) was observed when the drug was injected twice at intervals of 1.0 and 1.5 h at either dose tested (1.5 mg/kg and 0.75 mg/kg, respectively). Inducing ketanserin-sensitive HTRs, which are dependent on environmental valences and which show signs of tachyphylaxis and tolerance, 25CN-NBOH shares striking features common to serotonergic hallucinogens. Given its distinct in vitro selectivity for 5-HT2A over non5-HT2 receptors and its behavioral dynamics, 25CN NBOH appears to be a powerful tool for dissection of receptor-specific cortical circuit dynamics, including 5-HT2A related psychoactivity. PMID- 29467650 TI - Additive Dose Response Models: Explicit Formulation and the Loewe Additivity Consistency Condition. AB - High-throughput techniques allow for massive screening of drug combinations. To find combinations that exhibit an interaction effect, one filters for promising compound combinations by comparing to a response without interaction. A common principle for no interaction is Loewe Additivity which is based on the assumption that no compound interacts with itself and that two doses from different compounds having the same effect are equivalent. It then should not matter whether a component is replaced by the other or vice versa. We call this assumption the Loewe Additivity Consistency Condition (LACC). We derive explicit and implicit null reference models from the Loewe Additivity principle that are equivalent when the LACC holds. Of these two formulations, the implicit formulation is the known General Isobole Equation (Loewe, 1928), whereas the explicit one is the novel contribution. The LACC is violated in a significant number of cases. In this scenario the models make different predictions. We analyze two data sets of drug screening that are non-interactive (Cokol et al., 2011; Yadav et al., 2015) and show that the LACC is mostly violated and Loewe Additivity not defined. Further, we compare the measurements of the non interactive cases of both data sets to the theoretical null reference models in terms of bias and mean squared error. We demonstrate that the explicit formulation of the null reference model leads to smaller mean squared errors than the implicit one and is much faster to compute.

AB - Alzheimer's disease (AD), a neurodegenerative disorder, is most common cause of dementia witnessed among aged people. The pathophysiology of AD develops as a consequence of neurofibrillary tangle formation which consists of hyperphosphorylated microtubule associated tau protein and senile plaques of amyloid-beta (Abeta) peptide in specific brain regions that result in synaptic loss and neuronal death. The feeble buffering capacity of endoplasmic reticulum (ER) proteostasis in AD is evident through alteration in unfolded protein response (UPR), where UPR markers express invariably in AD patient's brain samples. Aging weakens UPRER causing neuropathology and memory loss in AD. This review highlights molecular signatures of UPRER and its key molecular alliance that are affected in aging leading to the development of intriguing neuropathologies in AD. We present a summary of recent studies reporting usage of small molecules as inhibitors or activators of UPRER sensors/effectors in AD that showcase avenues for therapeutic interventions. PMID- 29467651 TI - Functional G-Protein-Coupled Receptor (GPCR) Synthesis: The Pharmacological Analysis of Human Histamine H1 Receptor (HRH1) Synthesized by a Wheat Germ Cell Free Protein Synthesis System Combined with Asolectin Glycerosomes. AB - G-protein-coupled receptors (GPCRs) are membrane proteins distributed on the cell surface, and they may be potential drug targets. However, synthesizing GPCRs in vitro can be challenging. Recently, some cell-free protein synthesis systems have been shown to produce a large amount of membrane protein combined with chemical chaperones that include liposomes and glycerol. Liposomes containing high concentrations of glycerol are known as glycerosomes, which are used in new drug delivery systems. Glycerosomes have greater morphological stability than liposomes. Proteoglycerosomes are defined as glycerosomes that contain membrane proteins. Human histamine H1 receptor (HRH1) is one of the most studied GPCRs. In this study, we synthesized wild-type HRH1 (WT-HRH1) proteoglycerosomes and D107A HRH1, (in which Asp107 was replaced by Ala) in a wheat germ cell-free protein synthesis system combined with asolectin glycerosomes. The mutant HRH1 has been reported to have low affinity for the H1 antagonist. In this study, the amount of synthesized WT-HRH1 in one synthesis reaction was 434 +/- 66.6 MUg (7.75 +/- 1.19 * 103pmol). The specific binding of [3H]pyrilamine to the WT-HRH1 proteoglycerosomes became saturated as the concentration of the radioligand increased. The dissociation constant (Kd) and maximum density (Bmax) of the synthesized WT-HRH1 were 9.76 +/- 1.25 nM and 21.4 +/- 0.936 pmol/mg protein, respectively. However, specific binding to D107A-HRH1 was reduced compared with WT-HRH1 and the binding did not become saturated. The findings of this study highlight that HRH1 synthesized using a wheat germ cell-free protein synthesis system combined with glycerosomes has the ability to bind to H1 antagonists.

AB - This study documents information on significant ethnomedicinal plants, which was collected from the traditional healers of three indigenous communities of Bangladesh. The documented data were quantitatively analyzed for the first time in this area. The information was obtained through open-ended, semi-structured questionnaires. The benefits, importance and coverage of ethnomedicine were expressed through several quantitative indices including Informant Consensus Factor (ICF), Use Value (UV), Frequency of Citation (FC), Relative Frequency of Citation (RFC) and Relative Importance Index (RI). The agreement of homogeneity between the present and previous studies and among the indigenous communities was evaluated using the Jaccard Index (JI). A total of 159 ethnomedicinal plant species, which were distributed in 132 genera under 62 families, were documented from 174 informants. Of these, 128 plants were native and 31 were exotic. Of a majority of documented species, herbs and leaves were the most utilized plant parts for the preparation of ethnomedicines (45.28%) whereas pastes (63.03%) were the most popular formulations. Among the documented species, the dominant families were the Asteraceae (14 species) and the Lamiaceae (12 species). The highest ICF value was 0.77 for digestive system disorders. Based on UVs, the five most commonly used ethnomedicinal plant species in the study area were Duabanga grandiflora (0.43), Zingiber officinale (0.41), Congea tomentosa (0.40), Matricaria chamomilla (0.33) and Engelhardtia spicata (0.28). The highest RFC was recorded for Rauvolfia serpentina (0.25). The highest RI value was calculated for both Scoparia dulcis and Leucas aspera (0.83). Importantly, 16 species were reported with new therapeutic uses and to our knowledge, 7 species described herein have never been ethnobotanically and pharmacologically studied, viz: Agastache urticifolia, Asarum cordifolium, C. tomentosa, E. spicata, Hypserpa nitida, Merremia vitifolia and Smilax odoratissima. The present study showed that traditional treatment using medicinal plants is still widespread in the study area. Documentation of new ethnomedicinal species with their therapeutic uses shall promote further phytochemical and pharmacological investigations and possibly, lead to the development of new drugs.

AB - Diabetes mellitus is an important risk factor for the development of heart pathology. Myocardial infarction is the cause of death occurring after prolonged ischemia of the coronary arteries. Restoration of blood flow is the first intervention against heart attack, although the process of restoring blood flow to the ischemic myocardium could cause additional injury. This phenomenon, termed myocardial ischemia-reperfusion (MI-R) injury, is characterized by the formation of oxygen radicals. Pistachios have significant glucose- and insulin-lowering effects and can improve the inflammatory contest by downregulating both the expression and the circulating levels of several metabolic risk markers. The monocyte/macrophage cell line J774 was used to assess the extent of protection by natural raw (NP) and roasted salted (RP) pistachios against lipopolysaccharide (LPS)-induced inflammation. Moreover, antioxidant activity of NP and RP was assessed in an in vivo model of paw edema in rats induced by carrageenan (CAR) injection in the paw. This study evaluates the antioxidant properties of pistachios on the inflammatory process associated with myocardial ischemia/reperfusion injury (I/R) in diabetic rats. Rats were pre-treated with either NP or RP pistachios (30 mg/kg) 18 h prior to the experimental procedure. Results: Here, we demonstrated that treatment with NP reduced myocardial tissue injury, neutrophil infiltration, adhesion molecules (ICAM-1, P-selectin) expression, proinflammatory cytokines (TNF-alpha, IL-1beta) production, nitrotyrosine and PAR formation, NF-kappaB expression and apoptosis (Bax, Bcl-2) activation. This data clearly showes modulation of the inflammatory process, associated with MI-R injury, following administration of pistachios. PMID- 29467655 TI - Atherosclerosis Is an Inflammatory Disease which Lacks a Common Anti-inflammatory Therapy: How Human Genetics Can Help to This Issue. A Narrative Review. AB - Atherosclerosis is a multifactorial disease triggered and sustained by different risk factors such as dyslipidemia, arterial hypertension, diabetes mellitus, smoke, etc. Since a couple of decades, a pivotal role for inflammation in its pathogenesis has been recognized and proved at molecular levels, and already described in many animal models. Despite all this knowledge, due to the complexity of the specific inflammatory process subtending atherosclerosis and to the fact that inflammation is also a protective response against microorganisms, no anti-inflammatory therapy has been rendered available in the therapeutic armamentarium against atherosclerosis and vascular events till 2017 when canakinumab in the first ad-hoc randomized clinical trial (RCT) proved for the first time that targeting specifically inflammation lowers cardiovascular (CV) events. From the genetic side, in the 90's and early 2000, several genetic markers in inflammatory pathway have been explored searching for an association with athero-thrombosis which gave seldom consistent results. Then, in the genomic era, plenty of genetic markers covering most of the genome have been analyzed at once without a priori information. The results coming from genome wide association studies (GWAS) have pinpointed some loci closed to inflammatory molecules consistently associated with atherosclerosis and CV consequences revamping the strict link between inflammation and atherosclerosis and suggesting some tailored target therapy. Whole-exome and whole-genome sequencing will come soon showing new and old loci associated with atherosclerosis suggesting new molecular targets or underlying which inflammatory pathway could be most attractive to target for blocking atherosclerosis even in its early stages.

AB - Objective: Type 5 phosphodiesterase inhibitors (PDE5i) are efficient drugs used for treatment of erectile dysfunction (ED); however, a large discontinuation rate due to major side effects is reported. The aim of this study was to evaluate the possible improvement of sildenafil (Sild) pharmacokinetics associated to the sublingual administration of the new available oro-dispersible film (ODF), compared to both the oro-dispersible tablet (ODT) and the film-coated tablet (FCT) as original per os formulation. Methods:In vitro disaggregation test, dissolution test, and permeation test in specific devices to estimate the trans mucosal absorption. In vivo analysis of serum Sild levels, by high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS), was performed in 20 patients with psychogenic ED receiving alternatively per os FCT or sublingual ODT or ODF, at an equal dosage (50 mg). Pharmacokinetic parameters of Sild and adverse drug reactions experienced after the dosing of each formulation were compared. Results:In vitro, ODF showed the highest time to disaggregation and an increased rate of permeation compared to both ODT and FCT (P = 0.017 and P = 0.008, respectively). In vivo, compared to both FCT and ODT, ODF showed a faster increase of serum Sild levels (serum levels at 15 min from dosing, respectively: 2.24 +/- 1.4 ng/ml FCT, 0.5 +/- 0.3 ng/ml ODT, and 13.5 +/- 9.1 ng/ml ODF; P < 0.01 and P < 0.05 vs. ODF) together with a higher drug bioavailability within 60 min from dosing (relative AUC60min vs. FCT, respectively: 100.0 +/- 44.9% FCT, 183.8 +/- 75.4% ODT, and 304.2 +/- 156.0% ODF). A trend toward lower peak serum levels was observed for ODF. Finally, ODF showed a lower prevalence of headache compared to FCT (1 vs. 35%; P < 0.05) and improved pattern of flushing and nasal congestion. Conclusion: Sublingual Sild ODF improves the drug tolerability through a likely modified pharmacokinetic, suggesting a possible implication also in the clinical efficacy profile. Sublingual administration of oro-dispersible formulations may represent a strategy to ameliorate the adherence to therapy with PDE5i, particularly in patients discouraged by side effects. PMID- 29467657 TI - Effects of Sodium and Amino Acid Substrate Availability upon the Expression and Stability of the SNAT2 (SLC38A2) Amino Acid Transporter. AB - The SNAT2 (SLC38A2) System A amino acid transporter mediates Na+-coupled cellular uptake of small neutral alpha-amino acids (AAs) and is extensively regulated in response to humoral and nutritional cues. Understanding the basis of such regulation is important given that AA uptake via SNAT2 has been linked to activation of mTORC1; a major controller of many important cellular processes including, for example, mRNA translation, lipid synthesis, and autophagy and whose dysregulation has been implicated in the development of cancer and conditions such as obesity and type 2 diabetes. Extracellular AA withdrawal induces an adaptive upregulation of SNAT2 gene transcription and SNAT2 protein stability but, as yet, the sensing mechanism(s) that initiate this response remain poorly understood although interactions between SNAT2 and its substrates may play a vital role. Herein, we have explored how changes in substrate (AA and Na+) availability impact upon the adaptive regulation of SNAT2 in HeLa cells. We show that while AA deprivation induces SNAT2 gene expression, this induction was not apparent if extracellular Na+ was removed during the AA withdrawal period. Furthermore, we show that the increase in SNAT2 protein stability associated with AA withdrawal is selectively repressed by provision of SNAT2 AA substrates (N methylaminoisobutyric acid and glutamine), but not non-substrates. This stabilization and substrate-induced repression were critically dependent upon the cytoplasmic N-terminal tail of SNAT2 (containing lysyl residues which are putative targets of the ubiquitin-proteasome system), because "grafting" this tail onto SNAT5, a related SLC38 family member that does not exhibit adaptive regulation, confers substrate-induced changes in stability of the SNAT2-5 chimeric transporter. In contrast, expression of SNAT2 in which the N-terminal lysyl residues were mutated to alanine rendered the transporter stable and insensitive to substrate-induced changes in protein stability. Intriguingly, SNAT2 protein stability was dramatically reduced in the absence of extracellular Na+ irrespective of whether substrate AAs were present or absent. Our findings indicate that the presence of extracellular Na+ (and potentially its binding to SNAT2) may be crucial for not only sensing SNAT2 AA occupancy and consequently for initiating the adaptive response under AA insufficient conditions, but for enabling substrate-induced changes in SNAT2 protein stability. PMID- 29467658 TI - How Do Structurally Distinct Compounds Exert Functionally Identical Effects in Combating Obesity? AB - Although the concept of inflammatory obesity remains to be widely accepted, a plethora of antibiotics, anti-inflammatory agents, mitochondrial uncouplers, and other structurally distinct compounds with unknown mechanisms have been demonstrated to exert functionally identical effects on weight reduction. Here we summarize a universal mechanism in which weight loss is modulated by mitochondrial biogenesis, which is correlated with conversion from the mitochondria-insufficient white adipose tissue to the mitochondria-abundant brown adipose tissue. This mechanistic description of inflammatory obesity may prove useful in the future for guiding pathology-based drug discovery for weight reduction. PMID- 29467659 TI - Transfer and Multi-task Learning in QSAR Modeling: Advances and Challenges. AB - Medicinal chemistry projects involve some steps aiming to develop a new drug, such as the analysis of biological targets related to a given disease, the discovery and the development of drug candidates for these targets, performing parallel biological tests to validate the drug effectiveness and side effects. Approaches as quantitative study of activity-structure relationships (QSAR) involve the construction of predictive models that relate a set of descriptors of a chemical compound series and its biological activities with respect to one or more targets in the human body. Datasets used to perform QSAR analyses are generally characterized by a small number of samples and this makes them more complex to build accurate predictive models. In this context, transfer and multi task learning techniques are very suitable since they take information from other QSAR models to the same biological target, reducing efforts and costs for generating new chemical compounds. Therefore, this review will present the main features of transfer and multi-task learning studies, as well as some applications and its potentiality in drug design projects. PMID- 29467654 TI - The P2X7 Receptor in Inflammatory Diseases: Angel or Demon? AB - Under physiological conditions, adenosine triphosphate (ATP) is present at low levels in the extracellular milieu, being massively released by stressed or dying cells. Once outside the cells, ATP and related nucleotides/nucleoside generated by ectonucleotidases mediate a high evolutionary conserved signaling system: the purinergic signaling, which is involved in a variety of pathological conditions, including inflammatory diseases. Extracellular ATP has been considered an endogenous adjuvant that can initiate inflammation by acting as a danger signal through the activation of purinergic type 2 receptors-P2 receptors (P2Y G-protein coupled receptors and P2X ligand-gated ion channels). Among the P2 receptors, the P2X7 receptor is the most extensively studied from an immunological perspective, being involved in both innate and adaptive immune responses. P2X7 receptor activation induces large-scale ATP release via its intrinsic ability to form a membrane pore or in association with pannexin hemichannels, boosting purinergic signaling. ATP acting via P2X7 receptor is the second signal to the inflammasome activation, inducing both maturation and release of pro-inflammatory cytokines, such as IL-1beta and IL-18, and the production of reactive nitrogen and oxygen species. Furthermore, the P2X7 receptor is involved in caspases activation, as well as in apoptosis induction. During adaptive immune response, P2X7 receptor modulates the balance between the generation of T helper type 17 (Th17) and T regulatory (Treg) lymphocytes. Therefore, this receptor is involved in several inflammatory pathological conditions. In infectious diseases and cancer, P2X7 receptor can have different and contrasting effects, being an angel or a demon depending on its level of activation, cell studied, type of pathogen, and severity of infection. In neuroinflammatory and neurodegenerative diseases, P2X7 upregulation and function appears to contribute to disease progression. In this review, we deeply discuss P2X7 receptor dual function and its pharmacological modulation in the context of different pathologies, and we also highlight the P2X7 receptor as a potential target to treat inflammatory related diseases. PMID- 29467660 TI - Advantages and Limitations of Current Imaging Techniques for Characterizing Liposome Morphology. AB - There are currently a number of imaging techniques available for evaluating the morphology of liposomes and other nanoparticles, with each having its own advantages and disadvantages that should be considered when interpreting data. Controlling and validating the morphology of nanoparticles is of key importance for the effective clinical translation of liposomal formulations. There are a number of physical characteristics of liposomes that determine their in vivo behavior, including size, surface characteristics, lamellarity, and homogeneity. Despite the great importance of the morphology of nanoparticles, it is generally not well-characterized and is difficult to control. Appropriate imaging techniques provide important details regarding the morphological characteristics of nanoparticles, and should be used in conjunction with other methods to assess physicochemical parameters. In this review, we will discuss the advantages and limitations of available imaging techniques used to evaluate liposomal formulations. PMID- 29467661 TI - Functionalized Surface Geometries Induce: "Bone: Formation by Autoinduction". AB - The induction of tissue formation, and the allied disciplines of tissue engineering and regenerative medicine, have flooded the twenty-first century tissue biology scenario and morphed into high expectations of a fulfilling regenerative dream of molecularly generated tissues and organs in assembling human tissue factories. The grand conceptualization of deploying soluble molecular signals, first defined by Turing as forms generating substances, or morphogens, stemmed from classic last century studies that hypothesized the presence of morphogens in several mineralized and non-mineralized mammalian matrices. The realization of morphogens within mammalian matrices devised dissociative extractions and chromatographic procedures to isolate, purify, and finally reconstitute the cloned morphogens, found to be members of the transforming growth factor-beta (TGF-beta) supergene family, with insoluble signals or substrata to induce de novo tissue induction and morphogenesis. Can we however construct macroporous bioreactors per se capable of inducing bone formation even without the exogenous applications of the osteogenic soluble molecular signals of the TGF-beta supergene family? This review describes original research on coral-derived calcium phosphate-based macroporous constructs showing that the formation of bone is independent of the exogenous application of the osteogenic soluble signals of the TGF-beta supergene family. Such signals are the molecular bases of the induction of bone formation. The aim of this review is to primarily describe today's hottest topic of biomaterials' science, i.e., to construct and define osteogenetic biomaterials' surfaces that per se, in its own right, do initiate the induction of bone formation. Biomaterials are often used to reconstruct osseous defects particularly in the craniofacial skeleton. Edentulism did spring titanium implants as tooth replacement strategies. No were else that titanium surfaces require functionalized geometric nanotopographic cues to set into motion osteogenesis independently of the exogenous application of the osteogenic soluble molecular signals. Inductive morphogenetic surfaces are the way ahead of biomaterials' science: the connubium of stem cells on primed functionalized surfaces precisely regulates gene expression and the induction of the osteogenic phenotype. PMID- 29467663 TI - Ranolazine Attenuates Trastuzumab-Induced Heart Dysfunction by Modulating ROS Production. AB - The ErbB2 blocker trastuzumab improves survival in oncologic patients, but can cause cardiotoxicity. The late Na+ current inhibitor ranolazine has been shown to counter experimental HF, including doxorubicin cardiotoxicity (a condition characterized by derangements in redox balance), by lowering the levels of reactive oxygen species (ROS). Since ErbB2 can modulate ROS signaling, we tested whether trastuzumab cardiotoxicity could be blunted by ranolazine via redox mediated mechanisms. Trastuzumab decreased fractional shortening and ejection fraction in mice, but ranolazine prevented heart dysfunction when co-administered with trastuzumab. Trastuzumab cardiotoxicity was accompanied by elevations in natriuretic peptides and matrix metalloproteinase 2 (MMP2) mRNAs, which were not elevated with co-treatment with ranolazine. Trastuzumab also increased cleavage of caspase-3, indicating activation of the proapoptotic machinery. Again, ranolazine prevented this activation. Interestingly, Neonatal Rat Ventricular Myocytes (NRVMs), labeled with MitoTracker Red and treated with trastuzumab, showed only a small increase in ROS compared to baseline conditions. We then stressed trastuzumab-treated cells with the beta-agonist isoproterenol to increase workload, and we observed a significant increase of probe fluorescence, compared with cells treated with isoproterenol alone, reflecting induction of oxidative stress. These effects were blunted by ranolazine, supporting a role for INa inhibition in the regulation of redox balance also in trastuzumab cardiotoxicity. PMID- 29467662 TI - Purinergic Signaling in Neuron-Astrocyte Interactions, Circadian Rhythms, and Alcohol Use Disorder. AB - Alcohol use disorder (AUD) is a debilitating condition marked by cyclic patterns of craving, use, and withdrawal. These pathological behaviors are mediated by multiple neurotransmitter systems utilizing glutamate, GABA, dopamine, ATP, and adenosine. In particular, purines such as ATP and adenosine have been demonstrated to alter the phase and function of the circadian clock and are reciprocally regulated by the clock itself. Importantly, chronic ethanol intake has been demonstrated to disrupt the molecular circadian clock and is associated with altered circadian patterns of activity and sleep. Moreover, ethanol has been demonstrated to disrupt purinergic signaling, while dysfunction of the purinergic system has been implicated in conditions of drug abuse such as AUD. In this review, we summarize our current knowledge regarding circadian disruption by ethanol, focusing on the reciprocal relationship that exists between oscillatory neurotransmission and the molecular circadian clock. In particular, we offer detailed explanations and hypotheses regarding the concerted regulation of purinergic signaling and circadian oscillations by neurons and astrocytes, and review the diverse mechanisms by which purinergic dysfuction may contribute to circadian disruption or alcohol abuse. Finally, we describe the mechanisms by which ethanol may disrupt or hijack endogenous circadian rhythms to induce the maladaptive behavioral patterns associated with AUD. PMID- 29467664 TI - Peak Velocity as an Alternative Method for Training Prescription in Mice. AB - Purpose: To compare the efficiency of an aerobic physical training program prescribed according to either velocity associated with maximum oxygen uptake (vVO2max) or peak running speed obtained during an incremental treadmill test (Vpeak_K) in mice. Methods: Twenty male Swiss mice, 60 days old, were randomly divided into two groups with 10 animals each: 1. group trained by vVO2max (GVO2), 2. group trained by Vpeak_K (GVP). After the adaptation training period, an incremental test was performed at the beginning of each week to adjust training load and to determine the amount of VO2 and VCO2 fluxes consumed, energy expenditure (EE) and run distance during the incremental test. Mice were submitted to 4 weeks of aerobic exercise training of moderate intensity (velocity referring to 70% of vVO2max and Vpeak_K) in a programmable treadmill. The sessions lasted from 30 to 40 min in the first week, to reach 60 min in the fourth week, in order to provide the mice with a moderate intensity exercise, totaling 20 training sessions. Results: Mice demonstrated increases in VO2max (ml.kg-1.min-1) (GVO2 = 49.1% and GVP = 56.2%), Vpeak_K (cm.s-1) (GVO2 = 50.9% and GVP = 22.3%), EE (ml.kg-0,75.min-1) (GVO2 = 39.9% and GVP = 51.5%), and run distance (cm) (GVO2 = 43.5% and GVP = 33.4%), after 4 weeks of aerobic training (time effect, P < 0.05); there were no differences between the groups. Conclusions: Vpeak_K, as well as vVO2max, can be adopted as an alternative test to determine the performance and correct prescription of systemized aerobic protocol training to mice. PMID- 29467665 TI - Analysis of microRNA Expression Profiles Induced by Yiqifumai Injection in Rats with Chronic Heart Failure. AB - Background: Yiqifumai Injection (YQFM) is clinically used to treat various cardiovascular diseases including chronic heart failure (CHF). The efficacy of YQFM for treating heart failure has been suggested, but the mechanism of action for pharmacological effects of YQFM is unclear. Methods: Echocardiography detection, left ventricular intubation evaluation, histopathology and immunohistochemical examination were performed in CHF rats to evaluate the cardioprotective effect of YQFM. Rat miRNA microarray and bioinformatics analysis were employed to investigate the differentially expressed microRNAs. In vitro models of AngII-induced hypertrophy and t-BHP induced oxidative stress in H9c2 myocardial cells were used to validate the anti-hypertrophy and anti-apoptosis effects of YQFM. Measurement of cell surface area, ATP content and cell viability, Real-time PCR and Western blot were performed. Results: YQFM significantly improved the cardiac function of CHF rats by increasing left ventricular ejection fraction and fractional shortening, decreasing left ventricular internal diameter and enhancing cardiac output. Seven microRNAs which have a reversible regulation by YQFM treatment were found. Among them, miR-21-3p and miR-542-3p are related to myocardial hypertrophy and cell proliferation, respectively and were further verified by RT-PCR. Target gene network was established and potential related signaling pathways were predicted. YQFM could significantly alleviate AngII induced hypertrophy in cellular model. It also significantly increased cell viabilities and ATP content in t-BHP induced apoptotic cell model. Western blot analysis showed that YQFM could increase the phosphorylation of Akt. Conclusion: Our findings provided scientific evidence to uncover the mechanism of action of YQFM on miRNAs regulation against CHF by miRNA expression profile technology. The results indicated that YQFM has a potential effect on alleviate cardiac hypertrophy and apoptosis in chronic heart failure. PMID- 29467666 TI - Time Course and Association of Functional and Biochemical Markers in Severe Semitendinosus Damage Following Intensive Eccentric Leg Curls: Differences between and within Subjects. AB - Purpose: To investigate the extent and evolution of hamstring muscle damage caused by an intensive bout of eccentric leg curls (ELCs) by (1) assessing the time course and association of different indirect markers of muscle damage such as changes in the force-generating capacity (FGC), functional magnetic resonance (fMRI), and serum muscle enzyme levels and (2) analyzing differences in the degree of hamstring muscle damage between and within subjects (limb-to-limb comparison). Methods: Thirteen male participants performed six sets of 10 repetitions of an ELC with each leg. Before and at regular intervals over 7 days after the exercise, FGC was measured with maximal isometric voluntary contraction (MVC). Serum enzyme levels, fMRI transverse relaxation time (T2) and perceived muscle soreness were also assessed and compared against the FGC. Results: Two groups of subjects were identified according to the extent of hamstring muscle damage based on decreased FGC and increased serum enzyme levels: high responders (n = 10, severe muscle damage) and moderate responders (n = 3, moderate muscle damage). In the high responders, fMRI T2 analysis revealed that the semitendinosus (ST) muscle suffered severe damage in the three regions measured (proximal, middle, and distal). The biceps femoris short head (BFsh) muscle was also damaged and there were significant differences in the FGC within subjects in the high responders. Conclusion: FGC and serum enzyme levels measured in 10 of the subjects from the sample were consistent with severe muscle damage. However, the results showed a wide range of peak MVC reductions, reflecting different degrees of damage between subjects (high and moderate responders). fMRI analysis confirmed that the ST was the hamstring muscle most damaged by ELCs, with uniform T2 changes across all the measured sections of this muscle. During intensive ELCs, the ST muscle could suffer an anomalous recruitment pattern due to fatigue and damage, placing an excessive load on the BFsh and causing it to perform a synergistic compensation that leads to structural damage. Finally, T2 and MVC values did not correlate for the leg with the smaller FGC decrease in the hamstring muscles, suggesting that long-lasting increases in T2 signals after FGC markers have returned to baseline values might indicate an adaptive process rather than damage. PMID- 29467667 TI - Absence of Rapid Propagation through the Purkinje Network as a Potential Cause of Line Block in the Human Heart with Left Bundle Branch Block. AB - Background: Cardiac resynchronization therapy is an effective device therapy for heart failure patients with conduction block. However, a problem with this invasive technique is the nearly 30% of non-responders. A number of studies have reported a functional line of block of cardiac excitation propagation in responders. However, this can only be detected using non-contact endocardial mapping. Further, although the line of block is considered a sign of responders to therapy, the mechanism remains unclear. Methods: Herein, we created two patient-specific heart models with conduction block and simulated the propagation of excitation based on a cellmodel of electrophysiology. In one model with a relatively narrow QRS width (176 ms), we modeled the Purkinje network using a thin endocardial layer with rapid conduction. To reproduce a wider QRS complex (200 ms) in the second model, we eliminated the Purkinje network, and we simulated the endocardial mapping by solving the inverse problem according to the actual mapping system. Results: We successfully observed the line of block using non-contact mapping in the model without the rapid propagation of excitation through the Purkinje network, although the excitation in the wall propagated smoothly. This model of slow conduction also reproduced the characteristic properties of the line of block, including dense isochronal lines and fractionated local electrocardiograms. Further, simulation of ventricular pacing from the lateral wall shifted the location of the line of block. By contrast, in the model with the Purkinje network, propagation of excitation in the endocardial map faithfully followed the actual propagation in the wall, without showing the line of block. Finally, switching the mode of propagation between the two models completely reversed these findings. Conclusions: Our simulation data suggest that the absence of rapid propagation of excitation through the Purkinje network is the major cause of the functional line of block recorded by non-contact endocardial mapping. The line of block can be used to identify responders as these patients loose rapid propagation through the Purkinje network. PMID- 29467668 TI - Identification and Functional Analysis of the First Aquaporin from Striped Stem Borer, Chilo suppressalis. AB - Aquaporins are integral membrane proteins some of which form high capacity water selective channels, promoting water permeation across cell membranes. In this study, we isolated the aquaporin transcript (CsDrip1) of Chilo suppressalis, one of the important rice pests. CsDrip1 included two variants, CsDrip1_v1 and CsDrip1_v2. Although CsDrip1_v2 sequence (>409 bp) was longer than CsDrip1_v1, they possessed the same open reading frame (ORF). Protein structure and topology of CsDrip1 was analyzed using a predicted model, and the results demonstrated the conserved properties of insect water-specific aquaporins, including 6 transmembrane domains, 2 NPA motifs, ar/R constriction region (Phe69, His194, Ser203, and Arg209) and the C-terminal peptide sequence ending in "SYDF." Our data revealed that the Xenopus oocytes expressing CsDrip1 indicated CsDrip1 could transport water instead of glycerol, trehalose and urea. Further, the transcript of CsDrip1 expressed ubiquitously but differentially in different tissues or organs and developmental stages of C. suppressalis. CsDrip1 mRNA exhibited the highest level of expression within hindgut and the third instar larvae. Regardless of pupae and adults, there were significantly different expression levels of CsDrip1 gene between male and female. Different from at low temperature, the transcript of CsDrip1 in larvae exposed to high temperature was increased significantly. Moreover, the mRNA levels of CsDrip1 in the third instar larvae, the fifth instar larvae, pupae (male and female), and adults (male and female) under different humidities were investigated. However, the mRNA levels of CsDrip1 of only female and male adults were changed remarkably. In conclusions, CsDrip1 plays important roles in maintaining water homeostasis in this important rice pest. PMID- 29467669 TI - Establishment and Evaluation of a Rat Model of Sidestream Cigarette Smoke-Induced Chronic Obstructive Pulmonary Disease. AB - Chronic obstructive pulmonary disease (COPD) is a common cause of mortality worldwide. The current lack of an animal model that can be established within a certain time frame and imitate the unique features of the disease is a major limiting factor in its study. The present study established and evaluated an animal model of COPD that represents the early and advanced stage features using short-, middle-, and long-term sidestream cigarette smoke (CS) exposure. One hundred and nine Sprague-Dawley rats were randomly divided into 10 groups for different periods of sidestream CS exposure or no exposure (i.e., normal groups). The rats were exposed to CS from 3R4F cigarettes in an exposure chamber. Histological analysis was performed to determine pathological changes. We also conducted open-field tests, lung function evaluations, and cytokine analysis of the blood serum, bronchoalveolar lavage fluid, and lung tissue. The lung tissue protein levels, blood gases, and were also analyzed. As the CS exposure time increased, the indicators associated with oxidative stress, inflammatory responses, and airway remodeling were greater in the CS exposure groups than in the normal group. At 24 and 36 weeks, the COPD model rats displayed the middle- and advanced-stage features of COPD, respectively. In the 8-week CS exposure group, after the CS exposure was stopped for 4 weeks, inflammatory responses and oxidative responses were ameliorated and lung function exacerbation was reduced compared with the 12-week CS exposure group. Therefore, we established a more adequate rat model of sidestream CS induced COPD, which will have great significance for a better understanding of the pathogenesis of COPD and drug effectiveness evaluation. PMID- 29467670 TI - Zinc-alpha2-Glycoprotein Is Associated with Obesity in Chinese People and HFD Induced Obese Mice. AB - Zinc-alpha2-glycoprotein (ZAG) plays an important role in the regulation of body weight, body fat, and glucose metabolism. In this study, we first measured ZAG levels in serum and ZAG mRNA levels in subcutaneous white adipose tissue (sWAT) among overweight/obese patients and lean control subjects. Second, we investigated the effects of ZAG administration on the body weight, body fat and glucose metabolism of high-fat diet (HFD)-induced obese ICR mice and the possible mechanisms involved. The results showed that serum ZAG and mRNA levels in sWAT were significantly decreased in overweight/obese patients and that both showed a negative association with body mass index (BMI) and body weight after adjustment for age and sex. Further partial correlation analysis found that ZAG mRNA expression was positively related with several WAT browning-related genes, including uncoupling protein 1 (UCP1) (r = 0.67) and peroxisome proliferator activated receptor gamma coactivator 1 alpha (PGC1a) (r = 0.60), in the sWAT of all subjects. Additionally, intraperitoneal injection of a ZAG expression plasmid (5 MUg/injection, four times a week) in HFD-induced obese mice for 8 weeks demonstrated that ZAG overexpression significantly decreased body weight and WAT mass, and greatly increased the glucose tolerance of obese mice, as shown by the intraperitoneal glucose tolerance test (IPGTT) and intraperitoneal insulin tolerance test (IPITT). The staining of UCP1-positive adipocytes was significantly stronger in the sWAT of ZAG-treated obese mice than in that of obese control mice. The mRNA and protein levels of PGC1alpha in sWAT were significantly increased to 2.2- and 5.3-fold, respectively, compared with HFD obese mice, and there was a strong positive correlation between the expression levels of Zag and Pgc1alpha in mouse sWAT (r = 0.74). A similar phenomenon was also observed in visceral white adipose tissue (vWAT): the mRNA and protein levels of PGC1alpha were increased to 1.9- and 3.6-fold, respectively, when obese mice were treated with ZAG. In conclusion, ZAG levels in both sWAT and serum are inversely related with BMI and body weight in Chinese subjects. The action of ZAG on body weight, fat mass and glucose metabolism may be realized through activating PGC1alpha expression in sWAT and vWAT, then promoting WAT browning in obese mice. PMID- 29467671 TI - TNF-alpha Increases Production of Reactive Oxygen Species through Cdk5 Activation in Nociceptive Neurons. AB - The participation of reactive oxygen species (ROS) generated by NOX1 and NOX2/NADPH oxidase has been documented during inflammatory pain. However, the molecular mechanism involved in their activation is not fully understood. We reported earlier a key role of Cyclin-dependent kinase 5 (Cdk5) during inflammatory pain. In particular, we demonstrated that TNF-alpha increased p35 expression, a Cdk5 activator, causing Cdk5-mediated TRPV1 phosphorylation followed by an increment in Ca2+ influx in nociceptive neurons and increased pain sensation. Here we evaluated if Cdk5 activation mediated by p35 transfection in HEK293 cells or by TNF-alpha treatment in primary culture of nociceptive neurons could increase ROS production. By immunofluorescence we detected the expression of catalytic subunit (Nox1 and Nox2) and their cytosolic regulators (NOXO1 and p47phox) of NOX1 and NOX2/NADPH oxidase complexes, and their co-localization with Cdk5/p35 in HEK293 cells and in nociceptive neurons. By using a hydrogen peroxide sensor, we detected a significant increase of ROS production in p35 transfected HEK293 cells as compared with control cells. This effect was significantly blocked by VAS2870 (NADPH oxidase inhibitor) or by roscovitine (Cdk5 activity inhibitor). Also by using another ROS probe named DCFH-DA, we found a significant increase of ROS production in nociceptive neurons treated with TNF-alpha and this effect was also blocked by VAS2870 or by roscovitine treatment. Interestingly, TNF-alpha increased immunodetection of p35 protein and NOX1 and NOX2/NADPH oxidase complexes in primary culture of trigeminal ganglia neurons. Finally, the cytosolic regulator NOXO1 was significantly translocated to plasma membrane after TNF-alpha treatment and roscovitine blocked this effect. Altogether these results suggest that Cdk5 activation is implicated in the ROS production by NOX1 and NOX2/NADPH oxidase complexes during inflammatory pain.

AB - Background: Hepatocellular carcinoma (HCC) is common and the second leading causes of cancer-related deaths. HCC usually occurs on the basis of chronic liver diseases. At present, the study of iron metabolism in chronic liver diseases was limited to chronic HCV infection, nonalcoholic fatty liver disease, and alcoholic liver disease. This study aimed to investigate the effect of serum iron levels on the progression of chronic HBV infection and the relationship with the prognosis of HBV-related HCC. Methods: A respective study involving 277 healthy individuals as controls (HC), 295 patients with chronic hepatitis B (CHB), 224 patients with HBV-related liver cirrhosis (HBV-related LC), and 586 patients with HBV- related HCC were enrolled in this study. Hematological parameters, HBVDNA and liver biochemistry were analyzed. Child-Pugh grade and BCLC stage of the HBV-related HCC patients were calculated. Results: The serum iron levels were lowest in the HBV- related HCC group as compared with HC, CHB, and HBV-related LC groups (35.07 +/- 6.97, 27.37 +/- 10.26, 24.53 +/- 10.36 vs. 17.90 +/- 0.14, P < 0.001). Strikingly, serum iron levels were lowest in HBV- related HCC patients with tumor size more than 10 cm as compared with HBV- related HCC patients with tumor size smaller than 3, 3-5, and 5-10 cm by subgroup analysis (22.12 +/- 0.94, 21.44 +/- 1.41, 15.65 +/- 0.98 vs. 13.36 +/- 1.15, P < 0.001). Serum iron levels significantly decreased with worsening Child-Pugh grades and BCLC stages in HBV related HCC group. In addition, serum iron levels was positively correlated with Retinol-Binding Protein, total bile acid, hemoglobin, and lymphocyte and negatively correlated with white blood cell (WBC) and platelet in HBV- related HCC group. ROC curve analysis showed serum iron levels at 15.1 MUmol/L as the optimal cut-off point for determining the survival of HBV-related HCC. By the Cox regression model analysis, serum iron levels <15.1 MUmol/l together with higher AFP levels, worse BCLC stages, and larger tumor size showed higher mortality of HBV-related HCC patients (hazard ratio = 2.280, 95% confidence interval, 1.815 2.865; P < 0.001). Conclusions: Serum iron levels affected the progression of chronic HBV infection. The prognosis of HBV- related HCC patients with serum iron levels <15.1 MUmol/l together with higher AFP levels, worse BCLC stages, and larger tumor lesion were poor. PMID- 29467673 TI - Gait Complexity and Regularity Are Differently Modulated by Treadmill Walking in Parkinson's Disease and Healthy Population. AB - Variability raises considerable interest as a promising and sensitive marker of dysfunction in physiology, in particular in neurosciences. Both internally (e.g., pathology) and/or externally (e.g., environment) generated perturbations and the neuro-mechanical responses to them contribute to the fluctuating dynamics of locomotion. Defective internal gait control in Parkinson's disease (PD), resulting in typical timing gait disorders, is characterized by the breakdown of the temporal organization of stride duration variability. Influence of external cue on gait pattern could be detrimental or advantageous depending on situations (healthy or pathological gait pattern, respectively). As well as being an interesting rehabilitative approach in PD, treadmills are usually implemented in laboratory settings to perform instrumented gait analysis including gait variability assessment. However, possibly acting as an external pacemaker, treadmill could modulate the temporal organization of gait variability of PD patients which could invalidate any gait variability assessment. This study aimed to investigate the immediate influence of treadmill walking (TW) on the temporal organization of stride duration variability in PD and healthy population. Here, we analyzed the gait pattern of 20 PD patients and 15 healthy age-matched subjects walking on overground and on a motorized-treadmill (randomized order) at a self-selected speed. The temporal organization and regularity of time series of walking were assessed on 512 consecutive strides and assessed by the application of non-linear mathematical methods (i.e., the detrended fluctuation analysis and power spectral density; and sample entropy, for the temporal organization and regularity of gait variability, respectively). A more temporally organized and regular gait pattern seems to emerge from TW in PD while no influence was observed on healthy gait pattern. Treadmill could afford the necessary framework to regulate gait rhythmicity in PD. Overall, the results support the hypothesis of a greater dependence to regulatory inputs as an explanatory factor of treadmill influence observed in PD. Also, since treadmill misrepresents the gait as more healthy than it is, the present findings underline that gait analysis using treadmill devices should be cautiously considered in PD and especially for gait variability assessment in gait lab. PMID- 29467674 TI - An Improved Dynamic Model for the Respiratory Response to Exercise. AB - Respiratory system modeling has been extensively studied in steady-state conditions to simulate sleep disorders, to predict its behavior under ventilatory diseases or stimuli and to simulate its interaction with mechanical ventilation. Nevertheless, the studies focused on the instantaneous response are limited, which restricts its application in clinical practice. The aim of this study is double: firstly, to analyze both dynamic and static responses of two known respiratory models under exercise stimuli by using an incremental exercise stimulus sequence (to analyze the model responses when step inputs are applied) and experimental data (to assess prediction capability of each model). Secondly, to propose changes in the models' structures to improve their transient and stationary responses. The versatility of the resulting model vs. the other two is shown according to the ability to simulate ventilatory stimuli, like exercise, with a proper regulation of the arterial blood gases, suitable constant times and a better adjustment to experimental data. The proposed model adjusts the breathing pattern every respiratory cycle using an optimization criterion based on minimization of work of breathing through regulation of respiratory frequency. PMID- 29467676 TI - Effect of Heart rate on Basketball Three-Point Shot Accuracy. AB - The three-point shot (3S) is a fundamental basketball skill used frequently during a game, and is often a main determinant of the final result. The aim of the study was to investigate the effect of different metabolic conditions, in terms of heart rates, on 3S accuracy (3S%) in 24 male (Under 17) basketball players (age 16.3 +/- 0.6 yrs). 3S performance was specifically investigated at different heart rates. All sessions consisted of 10 consecutive 3Ss from five different significant field spots just beyond the FIBA three-point line, i.e., about 7 m from the basket (two counter-clockwise "laps") at different heart rates: rest (0HR), after warm-up (50%HRMAX [50HR]), and heart rate corresponding to 80% of its maximum value (80%HRMAX [80HR]). We found that 50HR does not significantly decrease 3S% (-15%, P = 0.255), while 80HR significantly does when compared to 0HR (-28%, P = 0.007). Given that 50HR does not decrease 3S% compared to 0HR, we believe that no preliminary warm-up is needed before entering a game in order to specifically achieve a high 3S%. Furthermore, 3S training should be performed in conditions of moderate-to-high fatigued state so that a high 3S% can be maintained during game-play. PMID- 29467675 TI - PVAT and Its Relation to Brown, Beige, and White Adipose Tissue in Development and Function. AB - Adipose tissue is commonly categorized into three types with distinct functions, phenotypes, and anatomical localizations. White adipose tissue (WAT) is the major energy store; the largest depots of WAT are found in subcutaneous or intravisceral sites. Brown adipose tissue (BAT) is responsible for energy dissipation during cold-exposure (i.e., non-shivering thermogenesis) and is primarily located in the interscapular region. Beige or brite (brown-in-white) adipose tissue can be found interspersed in WAT and can attain a brown-like phenotype. These three types of tissues also have endocrine functions and play major roles in whole body metabolism especially in obesity and its co morbidities, such as cardiovascular disease. Over the last years, perivascular adipose tissue (PVAT) has emerged as an adipose organ with endocrine and paracrine functions. Pro and anti-inflammatory agents released by PVAT affect vascular health, and are implicated in the inflammatory aspects of atherosclerosis. PVAT shares several of the defining characteristics of brown adipose tissue, including its cellular morphology and expression of thermogenic genes characteristic for brown adipocytes. However, PVATs from different vessels are phenotypically different, and significant developmental differences exist between PVAT and other adipose tissues. Whether PVAT represents classical BAT, beige adipose tissue, or WAT with changing characteristics, is unclear. In this review, we summarize the current knowledge on how PVAT relates to other types of adipose tissue, both in terms of functionality, developmental origins, and its role in obesity-related cardiovascular disease and inflammation. PMID- 29467677 TI - Ginsenoside Rg1 Ameliorates Rat Myocardial Ischemia-Reperfusion Injury by Modulating Energy Metabolism Pathways. AB - As a major ingredient of Radix ginseng, ginsenoside Rg1 (Rg1) has been increasingly recognized to benefit the heart condition, however, the rationale behind the role is not fully understood. In vitro study in H9c2 cardiomyocytes has shown the potential of Rg1 to increase ATP content in the cells. We thus speculated that the protective effect of Rg1 on heart ischemia and reperfusion (I/R) injury implicates energy metabolism regulation. The present study was designed to verify this speculation. Male Sprague-Dawley rats were subjected to 30 min of occlusion of left coronary anterior descending artery followed by reperfusion for 90 min. Rg1 (5 mg/kg/h) was continuously administrated intravenously 30 min before occlusion until the end of reperfusion. Myocradial blood flow and heart function were monitored over the period of I/R. Myocardial infarct size, structure and apoptosis, energy metabolism, and change in RhoA signaling pathway were evaluated 90 min after reperfusion. Binding of Rg1 to RhoA was assessed using Surface Plasmon Resonance (SPR). Rg1 prevented I/R-elicited insults in myocardium, including myocardial infarction and apoptosis, decreased myocardial blood flow (MBF) and heart function, and alteration in myocardium structure. Rg1 restored the production of ATP in myocardium after I/R. Rg1 was able to bind to RhoA and down-regulate the activity of RhoA signaling pathway. These results indicated that Rg1 had protective potential against I/R-induced myocardial injury, which may be related to inhibiting myocardial apoptosis and modulating energy metabolism through binding to RhoA. PMID- 29467678 TI - Structural Immaturity of Human iPSC-Derived Cardiomyocytes: In Silico Investigation of Effects on Function and Disease Modeling. AB - Background: Human induced pluripotent stem cell-derived cardiomyocytes (hiPSC CMs) have emerged as a promising experimental tool for translational heart research and drug development. However, their usability as a human adult cardiomyocyte model is limited by their functional immaturity. Our aim is to analyse quantitatively those characteristics and how they differ from adult CMs. Methods and Results: We have developed a novel in silico model with all essential functional electrophysiology and calcium handling features of hiPSC-CMs. Importantly, the virtual cell recapitulates the immature intracellular ion dynamics that are characteristic for hiPSC-CMs, as quantified based our in vitro imaging data. The strong "calcium clock" is a source for a dual function of excitation-contraction coupling in hiPSC-CMs: action potential and calcium transient morphology vary substantially depending on the activation sequence of underlying ionic currents and fluxes that is altered in spontaneous vs. paced mode. Furthermore, parallel simulations with hiPSC-CM and adult cardiomyocyte models demonstrate the central differences. Results indicate that hiPSC-CMs translate poorly the disease specific phenotypes of Brugada syndrome, long QT Syndrome and catecholaminergic polymorphic ventricular tachycardia, showing less robustness and greater tendency for arrhythmic events than adult CMs. Based on a comparative sensitivity analysis, hiPSC-CMs share some features with adult CMs, but are still functionally closer to prenatal CMs than adult CMs. A database analysis of 3000 hiPSC-CM model variants suggests that hiPSC-CMs recapitulate poorly fundamental physiological properties of adult CMs. Single modifications do not appear to solve this problem, which is mostly contributed by the immaturity of intracellular calcium handling. Conclusion: Our data indicates that translation of findings from hiPSC-CMs to human disease should be made with great caution. Furthermore, we established a mathematical platform that can be used to improve the translation from hiPSC-CMs to human, and to quantitatively evaluate hiPSC-CMs development toward more general and valuable model for human cardiac diseases. PMID- 29467679 TI - The Endocannabinoid System across Postnatal Development in Transmembrane Domain Neuregulin 1 Mutant Mice. AB - The use of cannabis is a well-established component risk factor for schizophrenia, particularly in adolescent individuals with genetic predisposition for the disorder. Alterations to the endocannabinoid system have been found in the prefrontal cortex of patients with schizophrenia. Thus, we assessed whether molecular alterations exist in the endocannabinoid signalling pathway during brain development in a mouse model for the schizophrenia risk gene neuregulin 1 (Nrg1). We analysed transcripts encoding key molecules of the endocannabinoid system in heterozygous transmembrane domain Nrg1 mutant mice (Nrg1 TM HET), which is known to have increased sensitivity to cannabis exposure. Tissue from the prelimbic cortex and hippocampus of male and female Nrg1 TM HET mice and wild type-like littermates was collected at postnatal days (PNDs) 7, 10, 14, 21, 28, 35, 49, and 161. Quantitative polymerase chain reaction was conducted to assess mRNA levels of cannabinoid receptor 1 (CB1R) and enzymes for the synthesis and breakdown of the endocannabinoid 2-arachidonoylglycerol [i.e., diacylglycerol lipase alpha (DAGLalpha), monoglyceride lipase (MGLL), and alpha/beta-hydrolase domain-containing 6 (ABHD6)]. No sex differences were found for any transcripts in either brain region; thus, male and female data were pooled. Hippocampal and cortical mRNA expression of DAGLalpha, MGLL, and ABHD6 increased until PND 21-35 and then decreased and stabilised for the rest of postnatal development. Hippocampal CB1R mRNA expression increased until PND 21 and decreased after this age. Expression levels of these endocannabinoid markers did not differ in Nrg1 TM HET compared to control mice at any time point. Here, we demonstrate dynamic changes in the developmental trajectory of several key endocannabinoid system transcripts in the mouse brain, which may correspond with periods of endocannabinoid system maturation. Nrg1 TM HET mutation did not alter the developmental trajectory of the endocannabinoid markers assessed, suggesting that other mechanisms may be responsible for the exaggerated cannabinoid susceptibility in these mice. PMID- 29467680 TI - Defining a Brief Intervention for the Promotion of Psychological Well-being among Unemployed Individuals through Expert Consensus. AB - Background: Epidemiologic evidence highlights the harmful consequences of unemployment on health and well-being. This emphasizes the need to design low cost interventions to prevent the adverse mental health effects of unemployment. The main aim of this study was to create expert-consensus regarding development and implementation of a brief, sustainable, and effective intervention program for promoting mental health among unemployed. Methods: The Delphi technique entailed a selected panel of 75 experts from various relevant professional backgrounds. Panel members were asked to state their level of agreement (5-point Likert scale) regarding (a) required characteristics for an effective mental health intervention for unemployed people and (b) key variables for assessing the effectiveness of that intervention. Consensus was obtained throughout two rounds of data collection through e-mail contact, with structured questionnaires. Items of the questionnaire were based on literature reviews about community-based interventions for unemployed individuals. Results: Overall, 46 experts collaborated with the Delphi process (final participation rate: 61.3%). Based on a review of the literature, 185 items were identified and grouped into two broad categories (set of characteristics of the intervention and set of variables for effectiveness assessment), aggregating a total of 11 dimensions. The two Delphi rounds resulted in the selection of 35 characteristic items for the intervention program and 54 variables for its effectiveness assessment. Brief group interventions were considered to be effective and sustainable for mental health promotion in unemployment conditions if targeting mental health literacy, training interpersonal skills, and job-search skills. Conclusion: As agreed by the panel of experts, a brief, sustainable and effective intervention can be developed and implemented by accounting for unemployed capacity-building for mental health self-care and adequate job-searching attitudes and skills. These results should be further implemented in community and multisector-based standardized interventions, targeting mental health among unemployed people, ensuring adequate conditions for its effectiveness assessment. PMID- 29467682 TI - Promoting Personal Growth through Experiential Learning: The Case of Expressive Arts Therapy for Lecturers in Thailand. AB - The aim of the paper is to assess academic experiential learning in relation to academic lectures' perceived personal and professional growth. Sixteen PhD students (age ranged between 23 and 46, 10 male, 6 females) participated in an introduction to expressive art therapy. Qualitative methods according to phenomenological methodology was used. At the beginning and end of the 48-h course they were asked to draw themselves, and explain the differences between the two drawings. In addition participants were semi-structured interviewed about the course and its personal and professional aspects at the end of the course. The main themes were the carousal of emotional experience, the use of art means for growth, and, professional growth. Findings revealed a perceived growth in terms of family relationships, inter-personal skills, and professional role performance. PMID- 29467681 TI - Glutamate Levels and Resting Cerebral Blood Flow in Anterior Cingulate Cortex Are Associated at Rest and Immediately Following Infusion of S-Ketamine in Healthy Volunteers. AB - Progressive loss of brain tissue is seen in some patients with schizophrenia and might be caused by increased levels of glutamate and resting cerebral blood flow (rCBF) alterations. Animal studies suggest that the normalisation of glutamate levels decreases rCBF and prevents structural changes in hippocampus. However, the relationship between glutamate and rCBF in anterior cingulate cortex (ACC) of humans has not been studied in the absence of antipsychotics and illness chronicity. Ketamine is a noncompetitive N-methyl-D-aspartate receptor antagonist that transiently induces schizophrenia-like symptoms and neurobiological disturbances in healthy volunteers (HVs). Here, we used S-ketamine challenge to assess if glutamate levels were associated with rCBF in ACC in 25 male HVs. Second, we explored if S-ketamine changed the neural activity as reflected by rCBF alterations in thalamus (Thal) and accumbens that are connected with ACC. Glutamatergic metabolites were measured in ACC with magnetic resonance (MR) spectroscopy and whole-brain rCBF with pseudo-continuous arterial spin labelling on a 3-T MR scanner before, during, and after infusion of S-ketamine (total dose 0.375 mg/kg). In ACC, glutamate levels were associated with rCBF before (p < 0.05) and immediately following S-ketamine infusion (p = 0.03), but not during and after. S-Ketamine increased rCBF in ACC (p < 0.001) but not the levels of glutamate (p = 0.96). In subcortical regions, S-ketamine altered rCBF in left Thal (p = 0.03). Our results suggest that glutamate levels in ACC are associated with rCBF at rest and in the initial phase of an increase. Furthermore, S ketamine challenge transiently induces abnormal activation of ACC and left Thal that both are implicated in the pathophysiology of schizophrenia. Future longitudinal studies should investigate if increased glutamate and rCBF are related to the progressive loss of brain tissue in initially first-episode patients. PMID- 29467683 TI - Lacan and Adolescence: The Contemporary Clinic of the "Sexual Non-rapport" and Pornography. AB - This article explores two clinical phenomena-pornography and conspiracy thinking that are highly relevant today and can be observed specifically among adolescent boys in the early stages of post-puberty: conspiracy thinking and the viewing of pornographic videos. It shows that the Lacanian concepts of the Real (of puberty) and the sexual non-rapport help us understand the psychopathological aspects of these two phenomena. Watching pornographic material becomes equivalent to a conspiracy theory about the sexual non-rapport; both in fact deny the effect of what puberty introduces as radically new. PMID- 29467684 TI - Cognitive Remediation in Middle-Aged or Older Inpatients with Chronic Schizophrenia: A Randomized Controlled Trial in Korea. AB - Background: Accumulating evidence indicates that cognitive remediation (CR) is effective for improving various cognitive deficits in adult patients with schizophrenia. Although reports of brain plasticity in older adults and the service needs for chronic patients with schizophrenia are increasing, very few randomized controlled trials of CR have been conducted in middle-aged or older inpatients with chronic schizophrenia. We investigated the efficacy of individualized CR on the cognitive impairments of middle-aged or older inpatients with chronic schizophrenia within the context of comprehensive psychiatric rehabilitation (PR) by comparing the results obtained with PR only and treatment as usual (TAU). Method: Fifty-seven middle-aged and older individuals with chronic schizophrenia and mild to moderate cognitive deficits were enrolled. Thirty-eight who were undergoing PR were randomly assigned to CR + PR (N = 19) or PR-only (N = 19) groups. Nineteen participants who were undergoing TAU without CR or PR were evaluated pre- and post-treatment. Results: CR was easily provided and well received (drop-out rates = 5.3%) by middle-aged or older psychiatric inpatients. Compared to the PR-Only or TAU patients, patients in the CR + PR group showed greater improvement in executive functioning. Compared to TAU patients, CR + PR and PR-only patients showed greater improvement in logical memory. More patients in the CR + PR group improved clinically significantly in executive functioning and logical memory, compared with the PR-only and TAU patients. Conclusions: These results suggested that CR improved some cognitive deficits in middle-aged or older inpatients with chronic schizophrenia and that it was effective as an adjunctive treatment to the usual PR services provided in inpatient settings.

AB - Aims: The aim of the present study was to examine how executive functions are assessed in children and adolescents with Cerebral Palsy. Method: A systematic literature review was conducted using four bibliographic databases (WebScience, Scopus, PubMed, and Psycinfo), and only studies that evaluated at least one executive function were selected. Both the research and reporting of results were based on Cochrane's recommendations and PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines. Results: The instrument most frequently used was the D-KEFS. All studies point to the existence of impairments in the executive functions among children and adolescents with Cerebral Palsy with an impact on several cognitive and life domains. Interpretation: There is a need to further systematize the research protocols to study the executive functions and their assessment in the intervention context. Findings of this review presented a diversity of tests (e.g., D-KEFS) or tasks (e.g., The inhibitory ability task) used with children with Cerebral Palsy. However, no information was given about adaptations performed to the test/task to meet Cerebral Palsy's specificities. Future research could consider including this information, which is key both to researchers and practitioners. The results of this study have important implications and suggestions for future avenues and guidelines for research and practice. PMID- 29467686 TI - The Role of Personality in Daily Food Allergy Experiences. AB - Food allergies present numerous challenges to coping in everyday life. Even simple things like planning a lunch with a friend can be stressful for people with food allergies. But are some people more adversely impacted by having a food allergy than other people? This paper addressed this question by investigating whether individual differences in the Big Five personality traits (neuroticism, extraversion, openness, agreeableness, and conscientiousness) are related to food allergy-related problems in everyday life among adults with food allergies. Participants were 108 adults (85% female; mean age = 40.2; age range 18-87) with a physician-diagnosed food allergy [most commonly to gluten (54.6%), peanuts (21.3%), cow's milk (16.7%), and shellfish/seafood (16.7%)]. Participants completed an initial online survey that measured demographics, food allergy information, and personality traits using the Big Five Inventory (John et al., 1991). For 2 weeks, participants completed a daily online survey that queried the occurrence of 25 food allergy issues that day and participants' overall stress and mood that day. Neuroticism did not predict more frequent allergy issues or greater stress/poorer mood on days with more allergy issues. Instead, higher openness to experience predicted a range of issues including going hungry because there is no safe food available, problems finding suitable foods when grocery shopping, feeling anxious at social occasions involving food, being excluded, and feeling embarrassed and poorly understood about their food allergy. Conscientious people were less embarrassed or self-conscious about their food allergy, but they had more problems eating out, and their positive mood was more impaired by allergy issues than their less conscientious peers. Extraversion and agreeableness played minor roles. Personality testing can identify people that may have difficulty living with food allergies-such as those higher in openness to experience. PMID- 29467687 TI - "Homework Feedback Is...": Elementary and Middle School Teachers' Conceptions of Homework Feedback. AB - This study explored mathematics teachers' conceptions of the homework feedback focusing on four key aspects: definition, purpose, types, and perceived impact. Forty-seven teachers from elementary and middle schools participated in six focus groups. Data were analyzed using content analysis. To enhance the trustworthiness of findings, classroom observations were used for triangulation of data. Participants conceptualized homework feedback in three directions (i.e., teachers' feedback provided to students, students' feedback provided to teachers, and homework self-feedback), being teachers' monitoring of students' learning the purpose reported by most teachers. Participants also reported the types of homework feedback more frequently used in class (e.g., checking homework completion, checking homework on the board), and their perceived impact on students. Findings provide valuable information to deepen the understanding of the homework feedback process, which may help develop new avenues for future research. PMID- 29467688 TI - Editorial: Post-traumatic Stress in the Family. PMID- 29467689 TI - Sociality Mental Modes Modulate the Processing of Advice-Giving: An Event-Related Potentials Study. AB - People have different motivations to get along with others in different sociality mental modes (i.e., communal mode and market mode), which might affect social decision-making. The present study examined how these two types of sociality mental modes affect the processing of advice-giving using the event-related potentials (ERPs). After primed with the communal mode and market mode, participants were instructed to decide whether or not give an advice (profitable or damnous) to a stranger without any feedback. The behavioral results showed that participants preferred to give the profitable advice to the stranger more slowly compared with the damnous advice, but this difference was only observed in the market mode condition. The ERP results indicated that participants demonstrated more negative N1 amplitude for the damnous advice compared with the profitable advice, and larger P300 was elicited in the market mode relative to both the communal mode and the control group. More importantly, participants in the market mode demonstrated larger P300 for the profitable advice than the damnous advice, whereas this difference was not observed at the communal mode and the control group. These findings are consistent with the dual-process system during decision-making and suggest that market mode may lead to deliberate calculation for costs and benefits when giving the profitable advice to others. PMID- 29467690 TI - The Role of Book Features in Young Children's Transfer of Information from Picture Books to Real-World Contexts. AB - Picture books are an important source of new language, concepts, and lessons for young children. A large body of research has documented the nature of parent child interactions during shared book reading. A new body of research has begun to investigate the features of picture books that support children's learning and transfer of that information to the real world. In this paper, we discuss how children's symbolic development, analogical reasoning, and reasoning about fantasy may constrain their ability to take away content information from picture books. We then review the nascent body of findings that has focused on the impact of picture book features on children's learning and transfer of words and letters, science concepts, problem solutions, and morals from picture books. In each domain of learning we discuss how children's development may interact with book features to impact their learning. We conclude that children's ability to learn and transfer content from picture books can be disrupted by some book features and research should directly examine the interaction between children's developing abilities and book characteristics on children's learning. PMID- 29467692 TI - Actively Coping with Violation: Exploring Upward Dissent Patterns in Functional, Dysfunctional, and Deserted Psychological Contract End States. AB - Recently, scholars have emphasized the importance of examining how employees cope with psychological contract violation and how the coping process contributes to psychological contract violation resolution and post-violation psychological contracts. Recent work points to the important role of problem-focused coping. Yet, to date, problem-focused coping strategies have not been conceptualized on a continuum from constructive to destructive strategies. Consequently, potential differences in the use of specific types of problem-focused coping strategies and the role these different strategies play in the violation resolution process has not been explored. In this study, we stress the importance of focusing on different types of problem-focused coping strategies. We explore how employee upward dissent strategies, conceptualized as different forms of problem-focused coping, contribute to violation resolution and post-violation psychological contracts. Two sources of data were used. In-depth interviews with supervisors of a Dutch car lease company provided 23 case descriptions of employee-supervisor interactions after a psychological contract violation. Moreover, a database with descriptions of Dutch court sentences provided eight case descriptions of employee-organization interactions following a perceived violation. Based on these data sources, we explored the pattern of upward dissent strategies employees used over time following a perceived violation. We distinguished between functional (thriving and reactivation), dysfunctional (impairment and dissolution) and deserted psychological contract end states and explored whether different dissent patterns over time differentially contributed to the dissent outcome (i.e., psychological contract end state). The results of our study showed that the use of problem-focused coping is not as straightforward as suggested by the post-violation model. While the post-violation model suggests that problem focused coping will most likely contribute positively to violation resolution, we found that this also depends on the type of problem-focused coping strategy used. That is, more threatening forms of problem-focused coping (i.e., threatening resignation as a way to trigger one's manager/organization to resolve the violation) mainly contributed to dysfunctional and deserted PC end states. Yet, in some instances the use of these types of active coping strategies also contributed to functional violation resolution. These findings have important implications for the literature on upward dissent strategies and psychological contract violation repair. PMID- 29467691 TI - Neural Correlates of Facial Mimicry: Simultaneous Measurements of EMG and BOLD Responses during Perception of Dynamic Compared to Static Facial Expressions. AB - Facial mimicry (FM) is an automatic response to imitate the facial expressions of others. However, neural correlates of the phenomenon are as yet not well established. We investigated this issue using simultaneously recorded EMG and BOLD signals during perception of dynamic and static emotional facial expressions of happiness and anger. During display presentations, BOLD signals and zygomaticus major (ZM), corrugator supercilii (CS) and orbicularis oculi (OO) EMG responses were recorded simultaneously from 46 healthy individuals. Subjects reacted spontaneously to happy facial expressions with increased EMG activity in ZM and OO muscles and decreased CS activity, which was interpreted as FM. Facial muscle responses correlated with BOLD activity in regions associated with motor simulation of facial expressions [i.e., inferior frontal gyrus, a classical Mirror Neuron System (MNS)]. Further, we also found correlations for regions associated with emotional processing (i.e., insula, part of the extended MNS). It is concluded that FM involves both motor and emotional brain structures, especially during perception of natural emotional expressions.

AB - Sensorimotor learning refers to improvements that occur through practice in the performance of sensory-guided motor behaviors. Leveraging novel technical capabilities of an immersive virtual environment, we probed the component kinematic processes that mediate sensorimotor learning. Twenty naive subjects performed a simulated marksmanship task modeled after Olympic Trap Shooting standards. We measured movement kinematics and shooting performance as participants practiced 350 trials while receiving trial-by-trial feedback about shooting success. Spatiotemporal analysis of motion tracking elucidated the ballistic and refinement phases of hand movements. We found systematic changes in movement kinematics that accompanied improvements in shot accuracy during training, though reaction and response times did not change over blocks. In particular, we observed longer, slower, and more precise ballistic movements that replaced effort spent on corrections and refinement. Collectively, these results leverage developments in immersive virtual reality technology to quantify and compare the kinematics of movement during early learning of full-body sensorimotor orienting.

AB - The current study aims to explore how the decision-making style of maximizing affects subjective well-being (SWB), which mainly focuses on the confirmation of the mediator role of regret and suppressing role of achievement motivation. A total of 402 Chinese undergraduate students participated in this study, in which they responded to the maximization, regret, and achievement motivation scales and SWB measures. Results suggested that maximizing significantly predicted SWB. Moreover, regret and achievement motivation (hope for success dimension) could completely mediate and suppress this effect. That is, two competing indirect pathways exist between maximizing and SWB. One pathway is through regret. Maximizing typically leads one to regret, which could negatively predict SWB. Alternatively, maximizing could lead to high levels of hope for success, which were positively correlated with SWB. Findings offered a complex method of thinking about the relationship between maximizing and SWB. PMID- 29467695 TI - Returning to Work after Childbirth in Europe: Well-Being, Work-Life Balance, and the Interplay of Supervisor Support. AB - Parents returning to work after the arrival of a new son or daughter is an important question for understanding the trajectory of people's lives and professional careers amid current debates about gender equality and work-life balance (WLB). Interestingly, current research concludes that general WLB practices at the workplace may be necessary in the specific case of women returning to work after childbirth because of the particular maternal and infant factors involved. However, WLB practices as a flexible arrangement may work against women because they may be viewed as a lack of organizational commitment. Therefore, research on this topic could benefit from considering supervisor support as a complement of such practices, but previous research has analyzed WLB and supervisor support separately and scarcely. To fill this gap in the literature, we use two sub-samples of 664 female employees and 749 male employees with children under the age of one from 27 European countries participating in the 6th European Working Conditions Survey (EWCS-2015) to study the impact of perceived WLB on European women's perceived well-being after childbirth, in contrast with previous literature. We also analyze the impact of perceived supervisor support (SS) and its interaction with perceived WLB on women's well being after childbirth, and explore differences with men after childbirth, a collective underexplored by the literature. We find significant gender differences on the relative impact of WLB, SS, and their interaction on perceived job well-being. Our results have important implications for human resource practices in organizations. In particular, they suggest that gendered WLB practices should be encouraged, and stress the relevance of the human factor over human resource practices in addressing the difficulties that women returning to work face after childbirth.

AB - Substantial evidence suggests that beauty is associated with the survival and reproduction of organisms. Landscape architecture is composed of a series of natural elements that have significant evolutionary implications. The present study used one pilot material ratings and three experiments to examine the mechanisms of aesthetic appraisals of landscape architecture. The results confirmed that landscape architecture elicited a sense of beauty and captured visual attention more easily than other types of architecture during explicit aesthetic rating task (Experiment 1) and implicit aesthetic perception task (dot probe paradigm, Experiment 2). Furthermore, the spatial cueing paradigm revealed that response latencies were significantly faster for landscape architecture than non-landscape architecture on valid trials, but there was no significant difference in this contrast on invalid trials at 150-ms stimulus onset asynchrony (SOA, Experiment 3a). At 500-ms SOA (Experiment 3b), participants responded significantly faster for landscape architecture on valid trials, but reacted significantly slower for landscape architecture on invalid trials. The findings indicated that the beauty of landscape architecture can be perceived implicitly, and only faster orienting of attention, but not delayed disengagement of attention was generated at early stages of the processing of landscape architecture. However, the attentional bias at later stages of attentional processes may be resulted from both faster orienting of attention and delayed disengagement of attention from landscape architecture photographs. PMID- 29467697 TI - Disgust, Sadness, and Appraisal: Disgusted Consumers Dislike Food More Than Sad Ones. AB - According to the affect-as-information framework, consumers base judgments on their feelings. Disgust is associated with two kinds of appraisal: one in which the consumer avoids and distances him/herself immediately from the object concerned, and another in which the consumer is disgusted due to contamination and impurities within the environment. The first instance indicates that disgust can decrease a consumer's preference for a product, regardless of its category. In contrast, the second case suggests that a product's degree of depreciation is greater in products vulnerable to contamination, such as foods. However, it remains largely unknown how incidental disgust affects product preferences in accordance with the two appraisal-related goals. The present research investigates how incidental disgust (as opposed to sadness, an equally valenced but distinct emotion of appraisal) influences consumer preferences for products with or without a risk of contamination. Twenty-four participants repeatedly judged foods or household products after seeing an emotional image (conveying disgust, sadness, or neutrality). Foods and household products are the two representative product categories in grocery stores, but only foods are associated with a risk of contamination. The results showed that incidental disgust led to negative evaluations of both types of products; however, compared to sadness, incidental disgust demonstrated a stronger negative effect on preference for foods than household products. These findings elucidate that disgust and the appraisal of contamination specifically devalue foods, and broaden the application of the appraisal-information framework in consumer settings. PMID- 29467698 TI - Dual Systems for Spatial Updating in Immediate and Retrieved Environments: Evidence from Bias Analysis. AB - The spatial updating and memory systems are employed during updating in both the immediate and retrieved environments. However, these dual systems seem to work differently, as the difference of pointing latency and absolute error between the two systems vary across environments. To verify this issue, the present study employed the bias analysis of signed errors based on the hypothesis that the transformed representation will bias toward the original one. Participants learned a spatial layout and then either stayed in the learning location or were transferred to a neighboring room directly or after being disoriented. After that, they performed spatial judgments from perspectives aligned with the learning direction, aligned with the direction they faced during the test, or a novel direction misaligned with the two above-mentioned directions. The patterns of signed error bias were consistent across environments. Responses for memory aligned perspectives were unbiased, whereas responses for sensorimotor aligned perspectives were biased away from the memory aligned perspective, and responses for misaligned perspectives were biased toward sensorimotor aligned perspectives. These findings indicate that the spatial updating system is consistently independent of the spatial memory system regardless of the environments, but the updating system becomes less accessible as the environment changes from immediate to a retrieved one. PMID- 29467699 TI - When Project Commitment Leads to Learning from Failure: The Roles of Perceived Shame and Personal Control. AB - Facing a remarkably changing world, researchers have gradually shifted emphasis from successful experiences to failures. In the current study, we build a model to explore the relationship between project commitment and learning from failure, and test how emotion (i.e., perceived shame after failure) and cognition (i.e., attribution for failure) affect this process. After randomly selecting 400 firms from the list of high-tech firms reported by the Beijing Municipal Science and Technology Commission, we use a two-wave investigation of the employees, and the final sample consists of 140 teams from 58 companies in the technology industry in mainland China. The results provide evidence for the positive role of personal control attribution in the relationship between project commitment and learning from failure. However, in contrast to previous studies, perceived shame, as the negative emotion after failed events, could bring desirable outcomes during this process. Based on the results, we further expand a model to explain the behavioral responses after failure, and the implications of our findings for research and practice are discussed. The failures and reverses which await men - and one after another sadden the brow of youth - add a dignity to the prospect of human life, which no Arcadian success would do. -Henry David Thoreau. PMID- 29467700 TI - Development and Preliminary Validation of the Salzburg Emotional Eating Scale. AB - Existing self-report questionnaires for the assessment of emotional eating do not differentiate between specific types of emotions and between increased or decreased food intake in response to these emotions. Therefore, we developed a new measure of emotional eating-the Salzburg Emotional Eating Scale (SEES)-for which higher scores indicate eating more than usual in response to emotions and lower scores indicate eating less than usual in response to emotions. In study 1, a pool of items describing 40 emotional states was used. Factor analysis yielded four factors, which represented both positive (happiness subscale) and negative emotions (sadness, anger, and anxiety subscales). Subsequently, the scale was reduced to 20 items (5 items for each subscale) and its four-factor structure was replicated in studies 2 and 3. In all three studies, internal consistencies of each subscale were alpha > 0.70 and mean subscale scores significantly differed from each other such that individuals reported the strongest tendency to eat more than usual when being sad and the strongest tendency to eat less than usual when being anxious (sadness > happiness > anger > anxiety). Higher scores on the happiness subscale related to lower scores on the negative emotions subscales, lower body mass index (BMI), and lower eating pathology. In contrast, higher scores on the negative emotions subscales related to lower scores on the happiness subscale, higher BMI, and higher eating pathology. The SEES represents a useful measure for the investigation of emotional eating by increasing both specificity (differentiation between specific emotional states) and breadth (differentiation between increase and decrease of food intake) in the assessment of the emotion-eating relationship. PMID- 29467701 TI - Are Expectations the Missing Link between Life History Strategies and Psychopathology? AB - Despite advances in knowledge and thinking about using life history theory to explain psychopathology there is still a missing link. That is, we all have a life history strategy, but not all of us develop mental health problems. We propose that the missing link is expectations - a mismatch between expected environmental conditions (including social) set by variations in life history strategies and the current environmental conditions. The mismatch hypothesis has been applied at the biological level in terms of health and disease and we believe that it can also be applied more broadly at the psychological level in terms of perceived expectations in the social environment and the resulting distress-psychopathology-that manifests when our expectations are not met. PMID- 29467702 TI - Are Leadership Fairness, Psychological Distress, and Role Stressors Interrelated? A Two-Wave Prospective Study of Forward and Reverse Relationships. AB - While previous research has mainly considered leadership as an antecedent to psychological distress and role stressors (i.e., role ambiguity and role conflict) among subordinates, a reverse relationship where these variables influence reports of leadership is also possible. To determine the directionality of the associations this two-wave prospective study assesses bidirectional relationships between fair leadership and role stressors and examines whether psychological distress mediates the reciprocal associations between fair leadership and the role stressors. Analyses were conducted in a sample of 6,790 Norwegian employees with a 2-year time-lag between measurement points. Fair leadership was associated with lower stability adjusted role ambiguity, but not role conflict, over time. Role conflict, but not role ambiguity, was related to subsequent reports of the immediate leader as less fair. Psychological distress did neither mediate the relationship between fair leadership and subsequent reports of role stressors, nor the association between role stressors and subsequent reports of fair leadership. The findings suggest that the fair leadership - role stressor association is not a one-directional process, but that exposure to role stressors also influence subordinates' perceptions of leadership. An implication of the findings is that theoretical models of organizational leadership should include this reverse impact of role stressors. To reduce the effects of role stressors, organizations could set consistent, clear and attractive goals and provide employees with necessary information for conducting their work tasks in order to help workers understand and master their roles at the workplace. PMID- 29467703 TI - The Effect of Eye Contact Is Contingent on Visual Awareness. AB - The present study explored how eye contact at different levels of visual awareness influences gaze-induced joint attention. We adopted a spatial-cueing paradigm, in which an averted gaze was used as an uninformative central cue for a joint-attention task. Prior to the onset of the averted-gaze cue, either supraliminal (Experiment 1) or subliminal (Experiment 2) eye contact was presented. The results revealed a larger subsequent gaze-cueing effect following supraliminal eye contact compared to a no-contact condition. In contrast, the gaze-cueing effect was smaller in the subliminal eye-contact condition than in the no-contact condition. These findings suggest that the facilitation effect of eye contact on coordinating social attention depends on visual awareness. Furthermore, subliminal eye contact might have an impact on subsequent social attention processes that differ from supraliminal eye contact. This study highlights the need to further investigate the role of eye contact in implicit social cognition. PMID- 29467704 TI - Father-Child Longitudinal Relationship: Parental Monitoring and Internet Gaming Disorder in Chinese Adolescents. AB - Although empirical studies have indicated that parents have an important role in preventing Internet gaming disorder in adolescents, longitudinal research on the parental predictors of Internet gaming disorder is lacking. We used a three-wave cross-lagged panel model to explore the reciprocal association between parental monitoring and Internet gaming disorder, and examined the different impacts of mother- and father-child relationships on this association. A sample of 1490 adolescents aged 10-15 years (M = 12.03, SD = 1.59; 45.4% female) completed assessments at all three points. The cross-lagged model revealed that (a) parental monitoring at T1 predicted lower Internet gaming disorder at T2, and greater Internet gaming disorder at T2 predicted lower parental monitoring at T3; (b) father-child relationship had a reciprocal, indirect effect on the relationship between parental monitoring and Internet gaming disorder, while mother-child relationship did not. These findings suggest that the parental effects (e.g., higher parental monitoring and better father-child relationship) might play a vital role in preventing Internet gaming disorder in adolescents. PMID- 29467705 TI - Development and Validation of a Spanish Version of the Grit-S Scale. AB - This paper describes the development and initial validation of a Spanish version of the Short Grit (Grit-S) Scale. The Grit-S Scale was adapted and translated into Spanish using the Translation, Review, Adjudication, Pre-testing, and Documentation model and responses to a preliminary set of items from a large sample of university students (N = 1,129). The resultant measure was validated using data from a large stratified random sample of young adults (N = 1,826). Initial validation involved evaluating the internal consistency of the adapted scale and its subscales and comparing the factor structure of the adapted version to that of the original scale. The results were comparable to results from similar analyses of the English version of the scale. Although the internal consistency of the subscales was low, the internal consistency of the full scale was well-within the acceptable range. A two-factor model offered an acceptable account of the data; however, when a single correlated error involving two highly similar items was included, a single factor model fit the data very well. The results support the use of overall scores from the Spanish Grit-S Scale in future research. PMID- 29467706 TI - Opening the Implicit Leadership Theories' Black Box: An Experimental Approach with Conjoint Analysis. AB - Although research on implicit leadership theories (ILTs) has concentrated on determining which attributes define a leadership prototype, little attention has been paid to testing the relative importance of each of these attributes for individuals' leadership perceptions. Building on socio-cognitive theories of impression processes, we experimentally explore the formation of leadership perceptions based on the recognition of six key attributes in a series of three experimental studies comprising 566 US-based participants recruited online via Amazon Mechanical Turk. Our results show that while certain attributes play an important role in the leader categorization process, others are less relevant. We also demonstrate that some attributes' importance is contingent on the presence of other attributes and on the leadership schema type activated in respondents' minds. Consistent with the Leadership Categorization Theory, our findings support the premise that individuals cognitively hold a superordinate leadership prototype, which imposes constraints on their more basic level prototypes. We discuss the implications of these results for leadership theory and practice.

PMID- 29467708 TI - Musical Scales in Tone Sequences Improve Temporal Accuracy. AB - Predicting the time of stimulus onset is a key component in perception. Previous investigations of perceived timing have focused on the effect of stimulus properties such as rhythm and temporal irregularity, but the influence of non temporal properties and their role in predicting stimulus timing has not been exhaustively considered. The present study aims to understand how a non-temporal pattern in a sequence of regularly timed stimuli could improve or bias the detection of temporal deviations. We presented interspersed sequences of 3, 4, 5, and 6 auditory tones where only the timing of the last stimulus could slightly deviate from isochrony. Participants reported whether the last tone was 'earlier' or 'later' relative to the expected regular timing. In two conditions, the tones composing the sequence were either organized into musical scales or they were random tones. In one experiment, all sequences ended with the same tone; in the other experiment, each sequence ended with a different tone. Results indicate higher discriminability of anisochrony with musical scales and with longer sequences, irrespective of the knowledge of the final tone. Such an outcome suggests that the predictability of non-temporal properties, as enabled by the musical scale pattern, can be a factor in determining the sensitivity of time judgments. PMID- 29467710 TI - Structural Covariance Network of Cortical Gyrification in Benign Childhood Epilepsy with Centrotemporal Spikes. AB - Benign childhood epilepsy with centrotemporal spikes (BECTS) is associated with cognitive and language problems. According to recent studies, disruptions in brain structure and function in children with BECTS are beyond a Rolandic focus, suggesting atypical cortical development. However, previous studies utilizing surface-based metrics (e.g., cortical gyrification) and their structural covariance networks at high resolution in children with BECTS are limited. Twenty six children with BECTS (15 males/11 females; 10.35 +/- 2.91 years) and 26 demographically matched controls (15 males/11 females; 11.35 +/- 2.51 years) were included in this study and subjected to high-resolution structural brain MRI scans. The gyrification index was calculated, and structural brain networks were reconstructed based on the covariance of the cortical folding. In the BECTS group, significantly increased gyrification was observed in the bilateral Sylvain fissures and the left pars triangularis, temporal, rostral middle frontal, lateral orbitofrontal, and supramarginal areas (cluster-corrected p < 0.05). Global brain network measures were not significantly different between the groups; however, the nodal alterations were most pronounced in the insular, frontal, temporal, and occipital lobes (FDR corrected, p < 0.05). In children with BECTS, brain hubs increased in number and tended to shift to sensorimotor and temporal areas. Furthermore, we observed significantly positive relationships between the gyrification index and age (vertex p < 0.001, cluster-level correction) as well as duration of epilepsy (vertex p < 0.001, cluster-level correction). Our results suggest that BECTS may be a condition that features abnormal over-folding of the Sylvian fissures and uncoordinated development of structural wiring, disrupted nodal profiles of centrality, and shifted hub distribution, which potentially represents a neuroanatomical hallmark of BECTS in the developing brain. PMID- 29467709 TI - Delayed Latency of Postural Muscles of Individuals with Intellectual Disabilities. AB - Individuals with intellectual disabilities (ID) (50 < IQ < 79) show impaired motor and postural control, these impairments are highly related to falls and injuries. Recent studies demonstrated these impairments are related with fine and gross motor development, which are more strongly associated with cognition, and consequently language for individuals with ID than for without ID. Despite these studies, little is known about the structure and functioning of this population's spinal cord, which is highly involved in postural control. The aim of our study was to assess the latency of the reflex responses in postural muscles after unexpected lateral external perturbations, in individuals with intellectual disabilities compared to typically developed participants. We assessed 16 participants with intellectual disabilities, 9 males and 7 females (aged 24.06 +/ 8.66 years) and 20 typical developed participants (CG), 11 females, 9 males, (aged 21.20+/-1.96 years). While the participants were in an upright standing position electromyography was used to collect data from M. obliquus externus abdominis (OE) muscles, which were activated by unpredictable perturbations applied by a servomotor on a hand-held grip, following the lateral external perturbation to the trunk. The intellectual disabilities group presented contralateral OE muscles latency of 85.71+/-27.24 ms, and CG group presented 68.62+/-10.25 ms, no differences was found. Ipsilateral OE muscles latency also did not differs between the groups, ID group showed 96.60+/-30.20 ms and CG group showed 95.57+/-33.53 ms. Our study furthers the knowledge about the muscular activity of individuals with intellectual disabilities. The present experimental results may suggest unique spinal cord processing of individuals with intellectual disabilities when they are faced with unexpected lateral external perturbations. PMID- 29467711 TI - Eye Movement Abnormalities in Multiple Sclerosis: Pathogenesis, Modeling, and Treatment. AB - Multiple sclerosis (MS) commonly causes eye movement abnormalities that may have a significant impact on patients' disability. Inflammatory demyelinating lesions, especially occurring in the posterior fossa, result in a wide range of disorders, spanning from acquired pendular nystagmus (APN) to internuclear ophthalmoplegia (INO), among the most common. As the control of eye movements is well understood in terms of anatomical substrate and underlying physiological network, studying ocular motor abnormalities in MS provides a unique opportunity to gain insights into mechanisms of disease. Quantitative measurement and modeling of eye movement disorders, such as INO, may lead to a better understanding of common symptoms encountered in MS, such as Uhthoff's phenomenon and fatigue. In turn, the pathophysiology of a range of eye movement abnormalities, such as APN, has been clarified based on correlation of experimental model with lesion localization by neuroimaging in MS. Eye movement disorders have the potential of being utilized as structural and functional biomarkers of early cognitive deficit, and possibly help in assessing disease status and progression, and to serve as platform and functional outcome to test novel therapeutic agents for MS. Knowledge of neuropharmacology applied to eye movement dysfunction has guided testing and use of a number of pharmacological agents to treat some eye movement disorders found in MS, such as APN and other forms of central nystagmus. PMID- 29467712 TI - Structured Reporting in Neuroradiology: Intracranial Tumors. AB - Purpose: The aim of this pilot study was to assess the clinical feasibility, diagnostic yield, advantages, and disadvantages of structured reporting for routine MRI-reading in patients with primary diagnosis of intracranial tumors as compared to traditional neuroradiological free text reporting. Methods: A structured MRI reporting template was developed covering pathological, anatomical, and functional aspects in an itemized fashion. Retrospectively, 60 consecutive patients with first diagnosis of an intracranial tumor were selected from the radiology information system/PACS system. Structured reporting was performed by a senior neuroradiologist, blinded to clinical and radiological data. Reporting times were measured per patient. The diagnostic content was compared to free text reporting which was independently performed on the same MRI exams by two other neuroradiologists. The comparisons were categorized per item as: "congruent," "partially congruent," "incongruent," or "not mentioned in free style report." Results: Tumor-related items: congruent findings were found for all items (17/17) with congruence rates ranging between 98 and 39% per item. Four items achieved congruence rates >=90%, 5 items >80%, and 9 items >=70%. Partially congruent findings were found for all items in up to 50% per item. Incongruent findings were present in 7/17 items in up to 5% per item. Free text reports did not mention 12 of 17 items (range 7-43% per item). Non-tumor-related items, including brain atrophy, microangiopathy, vascular pathologies, and various extracranial pathologies, which were not mentioned in free-text reports between 18 and 85% per item. Mean reporting time for structured reporting was 7:49 min (3:12-17:06 min). Conclusion: First results showed that expert structured reporting ensured reliable detection of all relevant brain pathologies along with reproducible documentation of all predefined diagnostic items, which was not always the case for free text reporting. A mean reporting time of 8 min per patient seems clinically feasible. PMID- 29467713 TI - Potential of Stem Cell-Based Therapy for Ischemic Stroke. AB - Ischemic stroke is one of the major health problems worldwide. The only FDA approved anti-thrombotic drug for acute ischemic stroke is the tissue plasminogen activator. Several studies have been devoted to assessing the therapeutic potential of different types of stem cells such as neural stem cells (NSCs), mesenchymal stem cells, embryonic stem cells, and human induced pluripotent stem cell-derived NSCs as treatments for ischemic stroke. The results of these studies are intriguing but many of them have presented conflicting results. Additionally, the mechanism(s) by which engrafted stem/progenitor cells exert their actions are to a large extent unknown. In this review, we will provide a synopsis of different preclinical and clinical studies related to the use of stem cell-based stroke therapy, and explore possible beneficial/detrimental outcomes associated with the use of different types of stem cells. Due to limited/short time window implemented in most of the recorded clinical trials about the use of stem cells as potential therapeutic intervention for stroke, further clinical trials evaluating the efficacy of the intervention in a longer time window after cellular engraftments are still needed. PMID- 29467714 TI - Brivaracetam in the Treatment of Patients with Epilepsy-First Clinical Experiences. AB - Objectives: To assess first clinical experiences with brivaracetam (BRV) in the treatment of epilepsies. Methods: Data on patients treated with BRV from February to December 2016 and with at least one clinical follow-up were collected from electronic patient records. Data on safety and efficacy were evaluated retrospectively. Results: In total, 93 patients were analyzed; 12 (12.9%) received BRV in monotherapy. The mean duration to follow-up was 4.85 months (MD = 4 months; SD = 3.63). Fifty-seven patients had more than one seizure per month at baseline and had a follow-up of more than 4 weeks; the rate of >=50% responders was 35.1% (n = 20) in this group, of which five (8.8%) patients were newly seizure-free. In 50.5% (47/93), patients were switched from levetiracetam (LEV) to BRV, of which 43 (46.2%) were switched immediately. Adverse events (AE) occurred in 39.8%, with 22.6% experiencing behavioral and 25.8% experiencing non behavioral AE. LEV-related AE (LEV-AE) were significantly reduced by switching to BRV. The discontinuation of BRV was reported in 26/93 patients (28%); 10 of those were switched back to LEV with an observed reduction of AE in 70%. For clinical reasons, 12 patients received BRV in monotherapy, 75% were seizure-free, and previous LEV-AE improved in 6/9 patients. BRV-related AE occurred in 5/12 cases, and five patients discontinued BRV. Conclusion: BRV seems to be a safe, easy, and effective option in the treatment of patients with epilepsy, especially in the treatment of patients who have psychiatric comorbidities and might not be good candidates for LEV treatment. BRV broadens the therapeutic spectrum and facilitates personalized treatment. PMID- 29467716 TI - Tissue Is More Important than Time in Stroke Patients Being Assessed for Thrombolysis. AB - Aim: The relative prognostic importance of modern imaging profiles compared with standard clinical characteristics is uncertain in acute stroke patients. In this study, we aimed to compare baseline multimodal CT imaging measures with known clinical predictors of patient outcome at 3 months [modified Rankin scale (mRS)]. Methods: We collected baseline, 24 h, and day 90 clinical and imaging data from acute ischemic stroke patients being assessed for thrombolytic therapy between 2010 and 2015 at a single center as part of a retrospective analysis. Results: 561 patients presenting within 4.5 h of ischemic stroke onset who were eligible for thrombolysis based on standard clinical criteria were assessed. Acute infarct core volume on CTP was the strongest univariate predictor of patient outcome (mRS 0-2, R2 0.497, p < 0.001), followed by collateral grade (mRS 0-2, R2 0.281, p < 0.001). The strongest baseline clinical predictor of outcome was National Institutes of Health Stroke Scale (NIHSS) (mRS 0-2, R2 = 0.203, p < 0.001). Time to treatment (mRS 0-2, R2 0.096, p = 0.01) and age (mRS 0-2, R2 0.027, p = 0.013) were relatively weak univariate baseline clinical predictors of 3-month outcome. In multivariate analysis, acute infarct core volume and collateral grade were the only significant baseline predictors of 3-month disability (both p < 0.001). Conclusion: In patients assessed for thrombolysis by combined clinical and multimodal CT criteria within 4.5 h of onset, the size of the CTP infarct core and collateral grade on multimodal CT were highly predictive of patient outcome. Standard clinical variables, including time to treatment and NIHSS, were not as strongly predictive as multimodal CT variables. PMID- 29467715 TI - Limb Remote Ischemic Conditioning: Mechanisms, Anesthetics, and the Potential for Expanding Therapeutic Options. AB - Novel and innovative approaches are essential in developing new treatments and improving clinical outcomes in patients with ischemic stroke. Remote ischemic conditioning (RIC) is a series of mechanical interruptions in blood flow of a distal organ, following end organ reperfusion, shown to significantly reduce infarct size through inhibition of oxidation and inflammation. Ischemia/reperfusion (I/R) is what ultimately leads to the irreversible brain damage and clinical picture seen in stroke patients. There have been several reports and reviews about the potential of RIC in acute ischemic stroke; however, the focus here is a comprehensive look at the differences in the three types of RIC (remote pre-, per-, and postconditioning). There are some limited uses of preconditioning in acute ischemic stroke due to the unpredictability of the ischemic event; however, it does provide the identification of biomarkers for clinical studies. Remote limb per- and postconditioning offer a more promising treatment during patient care as they can be harnessed during or after the initial ischemic insult. Though further research is needed, it is imperative to discuss the importance of preclinical data in understanding the methods and mechanisms involved in RIC. This understanding will facilitate translation to a clinically feasible paradigm for use in the hospital setting. PMID- 29467717 TI - Thioredoxin-1 Protects Spinal Cord from Demyelination Induced by Methamphetamine through Suppressing Endoplasmic Reticulum Stress and Inflammation. AB - Methamphetamine (METH) is a psychostimulant abused around the world. Emerging evidence indicates that METH causes brain damage. However, there are very few reports on METH-induced demyelination. Thioredoxin-1 (Trx-1) is a redox regulating protein and plays the roles in protecting neurons from various stresses. However, whether Trx-1 resists demyelination induced by METH has not been reported. In this study, we found that METH-induced thin myelin sheaths in spinal cord, whereas Trx-1 overexpression transgenic (TG) mice restored the myelin sheaths thickness. The expressions of myelin-associated glycoprotein, myelin basic protein, and cyclin-dependent kinase 5 were decreased by METH, whereas these alterations were blocked in Trx-1 TG mice. The expressions of procaspase-12 and procaspase-3 were decreased by METH, the expression of calpain1 was increased by METH, whereas the alterations were suppressed in Trx-1 TG mice. As same as, the expressions of the extracellular signal-regulated kinase, nuclear factor kappaB, tumor necrosis factor-alpha, and interleukin-1beta were induced by METH, which were suppressed in Trx-1 TG mice. These data suggest that Trx-1 may play a critical role in resisting the METH-mediated demyelination in spinal cord through regulating endoplasmic reticulum stress and inflammation pathways. PMID- 29467718 TI - On the Accurate Determination of Shock Wave Time-Pressure Profile in the Experimental Models of Blast-Induced Neurotrauma. AB - Measurement issues leading to the acquisition of artifact-free shock wave pressure-time profiles are discussed. We address the importance of in-house sensor calibration and data acquisition sampling rate. Sensor calibration takes into account possible differences between calibration methodology in a manufacturing facility, and those used in the specific laboratory. We found in house calibration factors of brand new sensors differ by less than 10% from their manufacturer supplied data. Larger differences were noticeable for sensors that have been used for hundreds of experiments and were as high as 30% for sensors close to the end of their useful lifetime. These observations were despite the fact that typical overpressures in our experiments do not exceed 50 psi for sensors that are rated at 1,000 psi maximum pressure. We demonstrate that sampling rate of 1,000 kHz is necessary to capture the correct rise time values, but there were no statistically significant differences between peak overpressure and impulse values for low-intensity shock waves (Mach number <2) at lower rates. We discuss two sources of experimental errors originating from mechanical vibration and electromagnetic interference on the quality of a waveform recorded using state-of-the-art high-frequency pressure sensors. The implementation of preventive measures, pressure acquisition artifacts, and data interpretation with examples, are provided in this paper that will help the community at large to avoid these mistakes. In order to facilitate inter-laboratory data comparison, common reporting standards should be developed by the blast TBI research community. We noticed the majority of published literature on the subject limits reporting to peak overpressure; with much less attention directed toward other important parameters, i.e., duration, impulse, and dynamic pressure. These parameters should be included as a mandatory requirement in publications so the results can be properly compared with others. PMID- 29467720 TI - The Steroid Hormone 20-Hydroxyecdysone Regulates the Conjugation of Autophagy Related Proteins 12 and 5 in a Concentration and Time-Dependent Manner to Promote Insect Midgut Programmed Cell Death. AB - Autophagy requires the conjugation of autophagy-related protein 12 (ATG12) to autophagy-related protein 5 (ATG5) through covalent attachment. However, the signals regulating ATG12-ATG5 conjugation are unclear. The larval midgut of lepidopteran insects performs autophagy and apoptosis sequentially during the transition of larvae to pupae under regulation by the steroid hormone 20 hydroxyecdysone (20E), thus representing a model to study steroid hormone regulation of ATG12-ATG5 conjugation. In the present study, using the lepidopteran insect Helicoverpa armigera as a model, we report that 20E regulates the conjugation of ATG12-ATG5 in a concentration and time-dependent manner. The ATG12-ATG5 conjugate was abundant in the epidermis, midgut, and fat body during metamorphosis from the larvae to the pupae; however, the ATG12-ATG5 conjugate level decreased at the time of pupation. At low concentrations (2-5 uM) over a short time course (1-48 h), 20E promoted the conjugation of ATG12-ATG5; however, at 10 uM and 72 h, 20E repressed the conjugation of ATG12-ATG5. ATG12 was localized in the larval midgut during metamorphosis. Knockdown of ATG12 in larvae caused death with delayed pupation, postponed the process of midgut programmed cell death (PCD), and repressed ATG8 (also called LC3-I) transformation to LC3-II and the cleavage of caspase-3; therefore, knockdown of ATG12 in larvae blocked both autophagy and apoptosis. Knockdown of ATG12 in H. armigera epidermis cell line cells also repressed 20E-induced autophagosome formation and caspase-3 activation. The results suggested that 20E plays key role in the regulation of ATG12-ATG5 conjugation in a concentration and time-dependent manner for autophagy or apoptosis, and that ATG12 is necessary by both autophagy and apoptosis during insect midgut PCD.

AB - Heat shock protein 60 (HSP60) is a key protein in the crosstalk between cellular stress and inflammation. However, the status of HSP60 in diabetes and obesity is unclear. In the present study, we investigated the hypothesis that HSP60 expression levels in the adipose tissue of human obese adults with and without diabetes are different and physical exercise might affect these levels. Subcutaneous adipose tissue (SAT) and blood samples were collected from obese adults with and without diabetes (n = 138 and n = 92, respectively, at baseline; n = 43 for both groups after 3 months of physical exercise). Conventional RT-PCR, immunohistochemistry, immunofluorescence, and ELISA were used to assess the expression and secretion of HSP60. Compared with obese adults without diabetes, HSP60 mRNA and protein levels were decreased in SAT in diabetic obese together with increased inflammatory marker expression and glycemic levels but lower VO2 Max. More interestingly, a 3-month physical exercise differentially affected HSP60 expression and the heat shock response but attenuated inflammation in both groups, as reflected by decreased endogenous levels of IL-6 and TNF-alpha. Indeed, HSP60 expression levels in SAT were significantly increased by exercise in the diabetes group, whereas they were decreased in the non-diabetes group. These results were further confirmed using immunofluorescence microscopy and anti HSP60 antibody in SAT. Exercise had only marginal effects on HSP60 secretion and HSP60 autoantibody levels in plasma in both obese with and without diabetes. Physical exercise differentially alleviates cellular stress in obese adults with and without diabetes despite concomitant attenuation of the inflammatory response. PMID- 29467721 TI - A Microfluidics and Agent-Based Modeling Framework for Investigating Spatial Organization in Bacterial Colonies: The Case of Pseudomonas Aeruginosa and H1 Type VI Secretion Interactions. AB - The factors leading to changes in the organization of microbial assemblages at fine spatial scales are not well characterized or understood. However, they are expected to guide the succession of community development and function toward specific outcomes that could impact human health and the environment. In this study, we put forward a combined experimental and agent-based modeling framework and use it to interpret unique spatial organization patterns of H1-Type VI secretion system (T6SS) mutants of P. aeruginosa under spatial confinement. We find that key parameters, such as T6SS-mediated cell contact and lysis, spatial localization, relative species abundance, cell density and local concentrations of growth substrates and metabolites are influenced by spatial confinement. The model, written in the accessible programming language NetLogo, can be adapted to a variety of biological systems of interest and used to simulate experiments across a broad parameter space. It was implemented and run in a high-throughput mode by deploying it across multiple CPUs, with each simulation representing an individual well within a high-throughput microwell array experimental platform. The microfluidics and agent-based modeling framework we present in this paper provides an effective means by which to connect experimental studies in microbiology to model development. The work demonstrates progress in coupling experimental results to simulation while also highlighting potential sources of discrepancies between real-world experiments and idealized models.

AB - This study was aimed to measure the impact of the application of a bio-fungicide against Botrytis cinerea on the microbiota involved in the alcoholic fermentation (AF) of Tempranillo Rioja wines. For this purpose, a bio-fungicide composed of the biological control bacterium Bacillus subtilis QST713 was applied to the vineyard. The microbial diversity was analyzed from grape biofilm to wine. Impact on microbial diversity was measured employing indexes assessed with the software PAST 3.10 P.D. Results were compared to non-treated samples and to samples treated with a chemical fungicide mainly composed by fenhexamid. Overall, the impact of the biological-fungicide (bio-fungicide) on the microbial diversity assessed for grape biofilm and for musts was not remarkable. Neither of the tested fungicides enhanced the growth of any species or acted against the development of any microbial groups. The bio-fungicide had no significant impact on the wine microbiota whereas the chemical fungicide caused a reduction of microbial community richness and diversity. Although environmental threats might generate a detriment of the microbial species richness, in this study the tested bio-fungicide did not modify the structure of the microbial community. Indeed, some of the Bacillus applied at the grape surface, were detected at the end of the AF showing its resilience to the harsh environment of the winemaking; in contrast, its impact on wine quality during aging is yet unknown. PMID- 29467722 TI - High Incidence of Pathogenic Streptococcus agalactiae ST485 Strain in Pregnant/Puerperal Women and Isolation of Hyper-Virulent Human CC67 Strain. AB - Group B streptococcus (GBS) is the major pathogen causing diseases in neonates, pregnant/puerperal women, cows and fish. Recent studies have shown that GBS may be infectious across hosts and some fish GBS strain might originate from human. The purpose of this study is to investigate the genetic relationship of CC103 strains that recently emerged in cows and humans, and explore the pathogenicity of clinical GBS isolates from human to tilapia. Ninety-two pathogenic GBS isolates were identified from 19 patients with different diseases and their evolution and pathogenicity to tilapia were analyzed. The multilocus sequence typing revealed that clonal complex (CC) 103 strain was isolated from 21.74% (20/92) of patients and ST485 strain was from 14.13% (13/92) patients with multiple diseases including neonates. Genomic evolution analysis showed that both bovine and human CC103 strains alternately form independent evolutionary branches. Three CC67 isolates carried gbs2018-C gene and formed one evolutionary branch with ST61 and ST67 strains that specifically infect dairy cows. Studies of interspecies transmission to tilapia found that 21/92 (22.83%) isolates including all ST23 isolates were highly pathogenic to tilapia and demonstrated that streptococci could break through the blood-brain barrier into brain tissue. In conclusions, CC103 strains are highly prevalent among pathogenic GBS from humans and have evolved into the highly pathogenic ST485 strains specifically infecting humans. The CC67 strains isolated from cows are able to infect humans through evolutionary events of acquiring CC17-specific type C gbs2018 gene and others. Human-derived ST23 pathogenic GBS strains are highly pathogenic to tilapia. PMID- 29467724 TI - Anodic and Cathodic Extracellular Electron Transfer by the Filamentous Bacterium Ardenticatena maritima 110S. AB - Ardenticatena maritima strain 110S is a filamentous bacterium isolated from an iron-rich coastal hydrothermal field, and it is a unique isolate capable of dissimilatory iron or nitrate reduction among the members of the bacterial phylum Chloroflexi. Here, we report the ability of A. maritima strain 110S to utilize electrodes as a sole electron acceptor and donor when coupled with the oxidation of organic compounds and nitrate reduction, respectively. In addition, multicellular filaments with hundreds of cells arranged end-to-end increased the extracellular electron transfer (EET) ability to electrodes by organizing filaments into bundled structures, with the aid of microbially reduced iron oxide minerals on the cell surface of strain 110S. Based on these findings, together with the attempt to detect surface-localized cytochromes in the genome sequence and the demonstration of redox-dependent staining and immunostaining of the cell surface, we propose a model of bidirectional electron transport by A. maritima strain 110S, in which surface-localized multiheme cytochromes and surface associated iron minerals serve as a conduit of bidirectional EET in multicellular filaments. PMID- 29467725 TI - Quantitative Viral Community DNA Analysis Reveals the Dominance of Single Stranded DNA Viruses in Offshore Upper Bathyal Sediment from Tohoku, Japan. AB - Previous studies on marine environmental virology have primarily focused on double-stranded DNA (dsDNA) viruses; however, it has recently been suggested that single-stranded DNA (ssDNA) viruses are more abundant in marine ecosystems. In this study, we performed a quantitative viral community DNA analysis to estimate the relative abundance and composition of both ssDNA and dsDNA viruses in offshore upper bathyal sediment from Tohoku, Japan (water depth = 500 m). The estimated dsDNA viral abundance ranged from 3 * 106 to 5 * 106 genome copies per cm3 sediment, showing values similar to the range of fluorescence-based direct virus counts. In contrast, the estimated ssDNA viral abundance ranged from 1 * 108 to 3 * 109 genome copies per cm3 sediment, thus providing an estimation that the ssDNA viral populations represent 96.3-99.8% of the benthic total DNA viral assemblages. In the ssDNA viral metagenome, most of the identified viral sequences were associated with ssDNA viral families such as Circoviridae and Microviridae. The principle components analysis of the ssDNA viral sequence components from the sedimentary ssDNA viral metagenomic libraries found that the different depth viral communities at the study site all exhibited similar profiles compared with deep-sea sediment ones at other reference sites. Our results suggested that deep-sea benthic ssDNA viruses have been significantly underestimated by conventional direct virus counts and that their contributions to deep-sea benthic microbial mortality and geochemical cycles should be further addressed by such a new quantitative approach. PMID- 29467727 TI - Phase Variable Expression of a Single Phage Receptor in Campylobacter jejuni NCTC12662 Influences Sensitivity Toward Several Diverse CPS-Dependent Phages. AB - Campylobacter jejuni NCTC12662 is sensitive to infection by many Campylobacter bacteriophages. Here we used this strain to investigate the molecular mechanism behind phage resistance development when exposed to a single phage and demonstrate how phase variable expression of one surface component influences phage sensitivity against many diverse C. jejuni phages. When C. jejuni NCTC12662 was exposed to phage F207 overnight, 25% of the bacterial cells were able to grow on a lawn of phage F207, suggesting that resistance develops at a high frequency. One resistant variant, 12662R, was further characterized and shown to be an adsorption mutant. Plaque assays using our large phage collection showed that seven out of 36 diverse capsular polysaccharide (CPS)-dependent phages could not infect 12662R, whereas the remaining phages formed plaques on 12662R with reduced efficiencies. Analysis of the CPS composition of 12662R by high-resolution magic angle spinning nuclear magnetic resonance (HR-MAS NMR) showed a diminished signal for O-methyl phosphoramidate (MeOPN), a phase variable modification of the CPS. This suggested that the majority of the 12662R population did not express this phase variable modification in the CPS, indicating that MeOPN serves as a phage receptor in NCTC12662. Whole genome analysis of 12662R showed a switch in the length of the phase variable homopolymeric G tract of gene 06810, encoding a putative MeOPN-transferase located in the CPS locus, resulting in a non functional protein. To confirm the role of 06810 in phage resistance development of NCTC12662, a 06810 knockout mutant in NCTC12662 was constructed and analyzed by HR-MAS NMR demonstrating the absence of MeOPN in the CPS of the mutant. Plaque assays using NCTC12662Delta06810 demonstrated that seven of our CPS-dependent Campylobacter phages are dependent on the presence of MeOPN for successful infection of C. jejuni, whereas the remaining 29 phages infect independently of MeOPN, although with reduced efficiencies. Our data indicate that CPS-dependent phages uses diverse mechanisms for their initial interaction with their C. jejuni host. PMID- 29467728 TI - Urbanization Reduces Transfer of Diverse Environmental Microbiota Indoors. AB - Expanding urbanization is a major factor behind rapidly declining biodiversity. It has been proposed that in urbanized societies, the rarity of contact with diverse environmental microbiota negatively impacts immune function and ultimately increases the risk for allergies and other immune-mediated disorders. Surprisingly, the basic assumption that urbanization reduces exposure to environmental microbiota and its transfer indoors has rarely been examined. We investigated if the land use type around Finnish homes affects the diversity, richness, and abundance of bacterial communities indoors. Debris deposited on standardized doormats was collected in 30 rural and 26 urban households in and near the city of Lahti, Finland, in August 2015. Debris was weighed, bacterial community composition determined by high throughput sequencing of bacterial 16S ribosomal RNA (rRNA) gene on the Illumina MiSeq platform, and the percentage of four different land use types (i.e., built area, forest, transitional, and open area) within 200 m and 2000 m radiuses from each household was characterized. The quantity of doormat debris was inversely correlated with coverage of built area. The diversity of total bacterial, Proteobacterial, Actinobacterial, Bacteroidetes, and Firmicutes communities decreased as the percentage of built area increased. Their richness followed the same pattern except for Firmicutes for which no association was observed. The relative abundance of Proteobacteria and particularly Gammaproteobacteria increased, whereas that of Actinobacteria decreased with increasing built area. Neither Phylum Firmicutes nor Bacteroidetes varied with coverage of built area. Additionally, the relative abundance of potentially pathogenic bacterial families and genera increased as the percentage of built area increased. Interestingly, having domestic animals (including pets) only altered the association between the richness of Gammaproteobacteria and diversity of Firmicutes with the built area coverage suggesting that animal ownership minimally affects transfer of environmental microbiota indoors from the living environment. These results support the hypothesis that people living in densely built areas are less exposed to diverse environmental microbiota than people living in more sparsely built areas. PMID- 29467726 TI - Mitochondrial Proteins Coded by Human Tumor Viruses. AB - Viruses must exploit the cellular biosynthetic machinery and evade cellular defense systems to complete their life cycles. Due to their crucial roles in cellular bioenergetics, apoptosis, innate immunity and redox balance, mitochondria are important functional targets of many viruses, including tumor viruses. The present review describes the interactions between mitochondria and proteins coded by the human tumor viruses human T-cell leukemia virus type 1, Epstein-Barr virus, Kaposi's sarcoma-associated herpesvirus, human hepatitis viruses B and C, and human papillomavirus, and highlights how these interactions contribute to viral replication, persistence and transformation. PMID- 29467729 TI - Polymorphism in Mitochondrial Group I Introns among Cryptococcus neoformans and Cryptococcus gattii Genotypes and Its Association with Drug Susceptibility. AB - Cryptococcosis, one of the most important systemic mycosis in the world, is caused by different genotypes of Cryptococcus neoformans and Cryptococcus gattii, which differ in their ecology, epidemiology, and antifungal susceptibility. Therefore, the search for new molecular markers for genotyping, pathogenicity and drug susceptibility is necessary. Group I introns fulfill the requisites for such task because (i) they are polymorphic sequences; (ii) their self-splicing is inhibited by some drugs; and (iii) their correct splicing under parasitic conditions is indispensable for pathogen survival. Here, we investigated the presence of group I introns in the mitochondrial LSU rRNA gene in 77 Cryptococcus isolates and its possible relation to drug susceptibility. Sequencing revealed two new introns in the LSU rRNA gene. All the introns showed high sequence similarity to other mitochondrial introns from distinct fungi, supporting the hypothesis of an ancient non-allelic invasion. Intron presence was statistically associated with those genotypes reported to be less pathogenic (p < 0.001). Further virulence assays are needed to confirm this finding. In addition, in vitro antifungal tests indicated that the presence of LSU rRNA introns may influence the minimum inhibitory concentration (MIC) of amphotericin B and 5 fluorocytosine. These findings point to group I introns in the mitochondrial genome of Cryptococcus as potential molecular markers for antifungal resistance, as well as therapeutic targets.

AB - Shigella is an important human food-borne zoonosis bacterial pathogen, and can cause clinically severe diarrhea. There is an urgent need to develop a specific, sensitive, and rapid methodology for detection of this pathogen. In this study, loop-mediated isothermal amplification (LAMP) combined with magnetic immunocapture assay (IC-LAMP) was first developed for the detection of Shigella in pure culture, artificial milk, and clinical stool samples. This method exhibited a detection limit of 8.7 CFU/mL. Compared with polymerase chain reaction, IC-LAMP is sensitive, specific, and reliable for monitoring Shigella. Additionally, IC-LAMP is more convenient, efficient, and rapid than ordinary LAMP, as it is more efficiently enriches pathogen cells without extraction of genomic DNA. Under isothermal conditions, the amplification curves and the green fluorescence were detected within 30 min in the presence of genomic DNA template. The overall analysis time was approximately 1 h, including the enrichment and lysis of the bacterial cells, a significantly short detection time. Therefore, the IC-LAMP methodology described here is potentially useful for the efficient detection of Shigella in various samples. PMID- 29467731 TI - Functional Analysis of the FZF1 Genes of Saccharomyces uvarum. AB - Being a sister species of Saccharomyces cerevisiae, Saccharomyces uvarum shows great potential regarding the future of the wine industry. The sulfite tolerance of most S. uvarum strains is poor, however. This is a major flaw that limits its utility in the wine industry. In S. cerevisiae, FZF1 plays a positive role in the transcription of SSU1, which encodes a sulfite efflux transport protein that is critical for sulfite tolerance. Although FZF1 has previously been shown to play a role in sulfite tolerance in S. uvarum, there is little information about its action mechanism. To assess the function of FZF1, two over-expression vectors that contained different FZF1 genes, and one FZF1 silencing vector, were constructed and introduced into a sulfite-tolerant S. uvarum strain using electroporation. In addition, an FZF1-deletion strain was constructed. Both of the FZF1-over-expressing strains showed an elevated tolerance to sulfite, and the FZF1-deletion strain showed the opposite effect. Repression of FZF1 transcription failed, however, presumably due to the lack of alleles of DCR1 and AGO. The qRT PCR analysis was used to examine changes in transcription in the strains. Surprisingly, neither over-expressing strain promoted SSU1 transcription, although MET4 and HAL4 transcripts significantly increased in both sulfite tolerance increased strains. We conclude that FZF1 plays a different role in the sulfite tolerance of S. uvarum compared to its role in S. cerevisiae. PMID- 29467732 TI - iTRAQ-Based Comparative Proteomic Analysis of Adult Schistosoma japonicum from Water Buffalo and Yellow Cattle. AB - Schistosomiasis japonicum is one of the most severe zoonotic diseases in China. Water buffalo and yellow cattle are important reservoir hosts and the main transmission sources of Schistosoma japonicum in endemic areas. The susceptibility of these two hosts to schistosome infection is different, as water buffaloes are less susceptible to S. japonicum than yellow cattle. In this study, iTRAQ-coupled LC-MS/MS was applied to compare the protein expression profiles of adult schistosomes recovered from water buffalo with those of yellow cattle. A total of 131 differentially expressed proteins (DEPs) were identified, including 46 upregulated proteins and 85 downregulated proteins. The iTRAQ results were confirmed by Western blotting and quantitative real-time PCR. Further analysis indicated that these DEPs were primarily involved in protein synthesis, transcriptional regulation, protein proteolysis, cytoskeletal structure and oxidative stress response processes. The results revealed that some of the differential expression molecules may affect the development and survival of schistosomes in these two natural hosts. Of note, this study provides useful information for understanding the interplay between schistosomes and their final hosts. PMID- 29467733 TI - Diversity of Rare and Abundant Prokaryotic Phylotypes in the Prony Hydrothermal Field and Comparison with Other Serpentinite-Hosted Ecosystems. AB - The Bay of Prony, South of New Caledonia, represents a unique serpentinite-hosted hydrothermal field due to its coastal situation. It harbors both submarine and intertidal active sites, discharging hydrogen- and methane-rich alkaline fluids of low salinity and mild temperature through porous carbonate edifices. In this study, we have extensively investigated the bacterial and archaeal communities inhabiting the hydrothermal chimneys from one intertidal and three submarine sites by 16S rRNA gene amplicon sequencing. We show that the bacterial community of the intertidal site is clearly distinct from that of the submarine sites with species distribution patterns driven by only a few abundant populations, affiliated to the Chloroflexi and Proteobacteria phyla. In contrast, the distribution of archaeal taxa seems less site-dependent, as exemplified by the co occurrence, in both submarine and intertidal sites, of two dominant phylotypes of Methanosarcinales previously thought to be restricted to serpentinizing systems, either marine (Lost City Hydrothermal Field) or terrestrial (The Cedars ultrabasic springs). Over 70% of the phylotypes were rare and included, among others, all those affiliated to candidate divisions. We finally compared the distribution of bacterial and archaeal phylotypes of Prony Hydrothermal Field with those of five previously studied serpentinizing systems of geographically distant sites. Although sensu stricto no core microbial community was identified, a few uncultivated lineages, notably within the archaeal order Methanosarcinales and the bacterial class Dehalococcoidia (the candidate division MSBL5) were exclusively found in a few serpentinizing systems while other operational taxonomic units belonging to the orders Clostridiales, Thermoanaerobacterales, or the genus Hydrogenophaga, were abundantly distributed in several sites. These lineages may represent taxonomic signatures of serpentinizing ecosystems. These findings extend our current knowledge of the microbial diversity inhabiting serpentinizing systems and their biogeography.

PMID- 29467735 TI - Genome-Based Characterization of Biological Processes That Differentiate Closely Related Bacteria. AB - Bacteriologists have strived toward attaining a natural classification system based on evolutionary relationships for nearly 100 years. In the early twentieth century it was accepted that a phylogeny-based system would be the most appropriate, but in the absence of molecular data, this approach proved exceedingly difficult. Subsequent technical advances and the increasing availability of genome sequencing have allowed for the generation of robust phylogenies at all taxonomic levels. In this study, we explored the possibility of linking biological characters to higher-level taxonomic groups in bacteria by making use of whole genome sequence information. For this purpose, we specifically targeted the genus Pantoea and its four main lineages. The shared gene sets were determined for Pantoea, the four lineages within the genus, as well as its sister-genus Tatumella. This was followed by functional characterization of the gene sets using the Kyoto Encyclopedia of Genes and Genomes (KEGG) database. In comparison to Tatumella, various traits involved in nutrient cycling were identified within Pantoea, providing evidence for increased efficacy in recycling of metabolites within the genus. Additionally, a number of traits associated with pathogenicity were identified within species often associated with opportunistic infections, with some support for adaptation toward overcoming host defenses. Some traits were also only conserved within specific lineages, potentially acquired in an ancestor to the lineage and subsequently maintained. It was also observed that the species isolated from the most diverse sources were generally the most versatile in their carbon metabolism. By investigating evolution, based on the more variable genomic regions, it may be possible to detect biologically relevant differences associated with the course of evolution and speciation. PMID- 29467736 TI - The Listeria monocytogenes Bile Stimulon under Acidic Conditions Is Characterized by Strain-Specific Patterns and the Upregulation of Motility, Cell Wall Modification Functions, and the PrfA Regulon. AB - Listeria monocytogenes uses a variety of transcriptional regulation strategies to adapt to the extra-host environment, the gastrointestinal tract, and the intracellular host environment. While the alternative sigma factor SigB has been proposed to be a key transcriptional regulator that facilitates L. monocytogenes adaptation to the gastrointestinal environment, the L. monocytogenes' transcriptional response to bile exposure is not well-understood. RNA-seq characterization of the bile stimulon was performed in two L. monocytogenes strains representing lineages I and II. Exposure to bile at pH 5.5 elicited a large transcriptomic response with ~16 and 23% of genes showing differential transcription in 10403S and H7858, respectively. The bile stimulon includes genes involved in motility and cell wall modification mechanisms, as well as genes in the PrfA regulon, which likely facilitate survival during the gastrointestinal stages of infection that follow bile exposure. The fact that bile exposure induced the PrfA regulon, but did not induce further upregulation of the SigB regulon (beyond that expected by exposure to pH 5.5), suggests a model where at the earlier stages of gastrointestinal infection (e.g., acid exposure in the stomach), SigB-dependent gene expression plays an important role. Subsequent exposure to bile induces the PrfA regulon, potentially priming L. monocytogenes for subsequent intracellular infection stages. Some members of the bile stimulon showed lineage- or strain-specific distribution when 27 Listeria genomes were analyzed. Even though sigB null mutants showed increased sensitivity to bile, the SigB regulon was not found to be upregulated in response to bile beyond levels expected by exposure to pH 5.5. Comparison of wildtype and corresponding DeltasigB strains newly identified 26 SigB-dependent genes, all with upstream putative SigB-dependent promoters. PMID- 29467738 TI - Worlds Apart - Transcriptome Profiles of Key Oral Microbes in the Periodontal Pocket Compared to Single Laboratory Culture Reflect Synergistic Interactions. AB - Periodontitis is a worldwide prevalent oral disease which results from dysbiosis of the periodontal microbiome. Some of the most active microbial players, e.g., Porphyromonas gingivalis, Treponema denticola, and Fusobacterium nucleatum, have extensively been studied in the laboratory, but it is unclear to which extend these findings can be transferred to in vivo conditions. Here we show that the transcriptional profiles of P. gingivalis, T. denticola, and F. nucleatum in the periodontal niche are distinct from those in single laboratory culture and exhibit functional similarities. GO (gene ontology) term enrichment analysis showed up-regulation of transporters, pathogenicity related traits and hemin/heme uptake mechanisms for all three species in vivo. Differential gene expression analysis revealed that cysteine proteases, transporters and hemin/heme-binding proteins were highly up-regulated in the periodontal niche, while genes involved in DNA modification were down-regulated. The data suggest strong interactions between those three species regarding protein degradation, iron up-take, and mobility in vivo, explaining their enhanced synergistic pathogenicity. We discovered a strikingly high frequency of Single Nucleotide Polymorphisms (SNPs) in vivo. For F. nucleatum we discovered a total of 127,729 SNPs in periodontal niche transcripts, which were found in similar frequency in health and disease and covered the entire genome, suggesting continuous evolution in the host. We conclude that metabolic interactions shape gene expression in vivo. Great caution is required when inferring pathogenicity of microbes from laboratory data, and microdiversity is an important adaptive trait of natural communities. PMID- 29467737 TI - Universal Vaccines and Vaccine Platforms to Protect against Influenza Viruses in Humans and Agriculture. AB - Influenza virus infections pose a significant threat to public health due to annual seasonal epidemics and occasional pandemics. Influenza is also associated with significant economic losses in animal production. The most effective way to prevent influenza infections is through vaccination. Current vaccine programs rely heavily on the vaccine's ability to stimulate neutralizing antibody responses to the hemagglutinin (HA) protein. One of the biggest challenges to an effective vaccination program lies on the fact that influenza viruses are ever changing, leading to antigenic drift that results in escape from earlier immune responses. Efforts toward overcoming these challenges aim at improving the strength and/or breadth of the immune response. Novel vaccine technologies, the so-called universal vaccines, focus on stimulating better cross-protection against many or all influenza strains. However, vaccine platforms or manufacturing technologies being tested to improve vaccine efficacy are heterogeneous between different species and/or either tailored for epidemic or pandemic influenza. Here, we discuss current vaccines to protect humans and animals against influenza, highlighting challenges faced to effective and uniform novel vaccination strategies and approaches.

AB - The elongation factor Tu has been identified as one of the most immunoreactive proteins that was recognized by human sera of GBS (group B streptococcus) positive patients. In this paper, we present the polypeptide-specific epitopes of the bacterial protein that are recognized by human antibodies: 28LTAAITTVLARRLP41 (peptide no. 3) and 294GQVLAKPGSINPHTKF309 (peptide no. 21). To determine the shortest amino acid sequence recognized by antibodies, truncation peptide libraries were prepared using the PEPSCAN method. The analysis of immunoreactivity of peptides with sera of GBS positive and negative women revealed that the most immunoreactive sequence was 306HTKF309. Moreover, we observed that this sequence also showed the highest specificity which was based on ratio of reactivity with sera of GBS positive relative to sera of GBS negative patients. Epitope was synthetized on Wang resin with the Fmoc strategy. Our results open the possibility to use 306HTKF309 peptide in diagnostic assays to determine Streptococcus agalactiae infection in humans. PMID- 29467740 TI - Genome-Wide Identification and Classification of Soybean C2H2 Zinc Finger Proteins and Their Expression Analysis in Legume-Rhizobium Symbiosis. AB - Root nodule symbiosis (RNS) is one of the most productive and economical systems for nitrogen fixation, and previous studies have shown that several nodule specific C2H2-zinc finger proteins (ZFPs) play important roles in symbiosis establishment and nodule function. However, C2H2-ZFPs are the most widespread ZFPs in eukaryotes, and a great variation of structure and function exist among the family members. It remains largely unclear whether or not special types of C2H2-ZF genes participate in symbiosis, especially in soybean. In the present study, we performed a genome-wide survey of soybean C2H2-ZF genes, and 321 soybean C2H2-ZF genes were identified and classified into 11 clearly distinguishable subsets (Gm-t1-SF, Gm-t2-SF, Gm-1i-Q-SF, Gm-1i-M-SF, Gm-1i-Z-SF, Gm-1i-D-SF, Gm-2i-Q-SF, Gm-2i-M-SF, Gm-2i-Mix-SF, Gm-3i-SF, and Gm-4i-SF) based on the arrangements, numbers, and types of C2H2-ZF domains. Phylogenetic and gene ontology analyses were carried out to assess the conserved sequence and GO function among these subsets, and the results showed that the classification of soybean C2H2-ZFPs was reasonable. The expression profile of soybean C2H2-ZFPs in multiple tissues showed that nearly half of soybean C2H2-ZFPs within different subsets had expressions in nodules, including a clustering branch consisting of 11 Gm-1i-Q-SF genes specifically expressed in symbiotic-relative tissues. RNA-Seq was used to identify symbiosis-related soybean C2H2-ZFPs, and the expression pattern of the soybean C2H2-ZFPs in roots and nodules at different development stages showed that soybean C2H2-ZFPs mainly played roles in nodule development or nodule function rather than nodulation signal transduction, and nearly half of these genes had high expressions and/or different expression patterns during soybean nodule development, especially for the six clustering branches of genes consisting of different subsets of C2H2-ZFPs. Furthermore, the selected symbiosis related soybean C2H2-ZFPs might function in legume-rhizobium symbiosis through regulating or interacting with other key proteins. Taken together, our findings provided useful information for the study on classification and conservative function of C2H2-ZFPs, and offered solid evidence for investigation of rhizobium symbiosis-related C2H2-ZFPs in soybean or other legumes.

AB - Past research demonstrating the importance plant-microbe interactions as drivers of ecosystem succession has focused on how plants condition soil microbial communities, impacting subsequent plant performance and plant community assembly. These studies, however, largely treat microbial communities as a black box. In this study, we sought to examine how emblematic shifts from early successional Alnus viridus ssp. sinuata (Sitka alder) to late successional Picea sitchensis (Sitka spruce) in primary succession may be reflected in specific belowground changes in bacterial community structure and nitrogen cycling related to the interaction of these two plants. We examined early successional alder-conditioned soils in a glacial forefield to delineate how alders alter the soil microbial community with increasing dominance. Further, we assessed the impact of late successional spruce plants on these early successional alder-conditioned microbiomes and related nitrogen cycling through a leachate addition microcosm experiment. We show how increasingly abundant alder select for particular bacterial taxa. Additionally, we found that spruce leachate significantly alters the composition of these microbial communities in large part by driving declines in taxa that are enriched by alder, including bacterial symbionts. We found these effects to be spruce specific, beyond a general leachate effect. Our work also demonstrates a unique influence of spruce on ammonium availability. Such insights bolster theory relating the importance of plant-microbe interactions with late successional plants and interspecific plant interactions more generally. PMID- 29467742 TI - Genetic Diversity and Phylogenetic Relationships of Coevolving Symbiont-Harboring Insect Trypanosomatids, and Their Neotropical Dispersal by Invader African Blowflies (Calliphoridae). AB - This study is about the inter- and intra-specific genetic diversity of trypanosomatids of the genus Angomonas, and their association with Calliphoridae (blowflies) in Neotropical and Afrotropical regions. Microscopic examination of 3,900 flies of various families, mostly Calliphoridae, revealed that 31% of them harbored trypanosomatids. Small subunit rRNA (SSU rRNA) barcoding showed that Angomonas predominated (46%) over the other common trypanosomatids of blowflies of genera Herpetomonas and Wallacemonas. Among Angomonas spp., A. deanei was much more common than the two-other species, A. desouzai and A. ambiguus. Phylogenetic analyses based on SSU rRNA, glycosomal glyceraldehyde-3-phosphate dehydrogenase (gGAPDH) and internal transcribed spacer rDNA (ITS rDNA) sequences revealed a marked genetic diversity within A. deanei, which comprised four infraspecific genotypes (Dea1-Dea4), and four corresponding symbiont genotypes (Kcr1-Kcr4). Host and symbiont phylogenies were highly congruent corroborating their co divergence, consistent with host-symbiont interdependent metabolism and symbiont reduced genomes shaped by a long coevolutionary history. We compared the diversity of Angomonas/symbionts from three genera of blowflies, Lucilia, Chrysomya and Cochliomyia. A. deanei, A. desouzai, and A. ambiguus were found in the three genera of blowflies in South America. In Africa, A. deanei and A. ambiguus were identified in Chrysomya. The absence of A. desouzai in Africa and its presence in Neotropical Cochliomyia and Lucilia suggests parasite spillback of A. desouzai into Chrysomya, which was most likely introduced four decades ago from Africa into the Neotropic. The absence of correlation between parasite diversity and geographic and genetic distances, with identical genotypes of A. deanei found in the Neotropic and Afrotropic, is consistent with disjunct distribution due to the recent human-mediated transoceanic dispersal of Angomonas by Chrysomya. This study provides the most comprehensive data gathered so far on the genetic repertoires of a genus of trypanosomatids found in flies from a wide geographical range. PMID- 29467743 TI - Genotypic and Phenotypic Diversity of Cryptococcus gattii VGII Clinical Isolates and Its Impact on Virulence. AB - The Cryptococcus gattii species complex harbors the main etiological agents of cryptococcosis in immunocompetent patients. C. gattii molecular type VGII predominates in the north and northeastern regions of Brazil, leading to high morbidity and mortality rates. C. gattii VGII isolates have a strong clinical relevance and phenotypic variations. These phenotypic variations among C. gattii species complex isolates suggest that some strains are more virulent than others, but little information is available related to the pathogenic properties of those strains. In this study, we analyzed some virulence determinants of C. gattii VGII strains (CG01, CG02, and CG03) isolated from patients in the state of Piaui, Brazil. The C. gattii R265 VGIIa strain, which was isolated from the Vancouver outbreak, differed from C. gattii CG01, CG02 and CG03 isolates (also classified as VGII) when analyzed the capsular dimensions, melanin production, urease activity, as well as the glucuronoxylomannan (GXM) secretion. Those differences directly reflected in their virulence potential. In addition, CG02 displayed higher virulence compared to R265 (VGIIa) strain in a cryptococcal murine model of infection. Lastly, we examined the genotypic diversity of these strains through Multilocus Sequence Type (MLST) and one new subtype was described for the CG02 isolate. This study confirms the presence and the phenotypic and genotypic diversity of highly virulent strains in the Northeast region of Brazil. PMID- 29467744 TI - Depth-Resolved Variations of Cultivable Bacteria and Their Extracellular Enzymes in the Water Column of the New Britain Trench. AB - Marine microorganisms and their extracellular enzymes (ECEs) play an important role in the remineralization of organic material by hydrolyzing high-molecular weight substrates to sizes sufficiently small to be transported through cell membrane, yet the diversity of the enzyme-producing bacteria and the types of ECEs involved in the degradation process are largely unknown. In this work, we investigated the diversity of cultivable bacteria and their ECEs and the potential activities of aminopeptidase in the water column at eight different depths of the New Britain Trench. There was a great diversity of cultivable bacteria and ECEs, and depth appears an important driver of the diversity. The 16S rRNA sequence analysis revealed that the cultivable bacteria were affiliated mostly with the phyla Proteobacteria and Actinobacteria, and the predominant genera were Pseudoalteromonas (62.7%) and Halomonas (17.3%). Moreover, 70.7% of the isolates were found to produce hydrolytic zone on casein and gelatin plates, in which Pseudoalteromonas was the predominant group, exhibiting relatively high protease production. Inhibitor analysis showed that the extracellular proteases from the isolated bacteria were serine proteases in the surface water and metalloproteases in the deep water. Meanwhile, the Vmax and Km of aminopeptidase exhibited a maximum in the surface water and low values in the deep bathy- and abyssopelagic water, indicating lower rates of hydrolysis and higher substrate affinity in the deeper waters. These results shed new insights into the diversity of the cultivable bacteria and bacterial ECEs and their likely biogeochemical functions in the trench environment. PMID- 29467745 TI - Small Non-coding RNA RyhB Mediates Persistence to Multiple Antibiotics and Stresses in Uropathogenic Escherichia coli by Reducing Cellular Metabolism. AB - As dormant phenotypic variants of bacteria, persisters account for many chronic infections affecting human health. Despite numerous studies, the role of small non-coding RNA (sRNA) in bacterial persistence has not been reported. To investigate the role of Hfq-interacting sRNA in persistence, we constructed the deletion mutants of 20 Hfq-interacting sRNAs (RyhB, GcvB, MgrR, RybB, MicF, SgrS, RprA, DicF, SsrS, FnrS, GadY, DsrA, OmrB, ArcZ, RyeB, RydC, OmrA, MicA, MicC, and ChiX) to assess their persistence capacity in uropathogenic Escherichia coli strain UTI89 and identified a new sRNA RyhB being involved in persister formation. The ryhB-knockout mutant had significant defect in persistence to a diverse range of antibiotics (levofloxacin, cefotaxime, gentamicin) and stresses (hyperosmosis, acid, and heat) in both exponential phase and stationary phase. In addition, the effect of RyhB on persistence was synergistic with ppGpp and Fur protein. RNA-Seq analysis indicated that the ryhB-knockout mutant had a hyperactive metabolic state compared with the parent strain. Interestingly, increased adenosine triphosphate (ATP) levels and altered NAD+/NADH ratios were observed in the ryhB-knockout mutant. Our findings represent a new level of persistence regulation via sRNA and may provide novel therapeutic targets for interventions. PMID- 29467746 TI - Genomic Diversity and Evolution of the Fish Pathogen Flavobacterium psychrophilum. AB - Flavobacterium psychrophilum, the etiological agent of rainbow trout fry syndrome and bacterial cold-water disease in salmonid fish, is currently one of the main bacterial pathogens hampering the productivity of salmonid farming worldwide. In this study, the genomic diversity of the F. psychrophilum species is analyzed using a set of 41 genomes, including 30 newly sequenced isolates. These were selected on the basis of available MLST data with the two-fold objective of maximizing the coverage of the species diversity and of allowing a focus on the main clonal complex (CC-ST10) infecting farmed rainbow trout (Oncorhynchus mykiss) worldwide. The results reveal a bacterial species harboring a limited genomic diversity both in terms of nucleotide diversity, with ~0.3% nucleotide divergence inside CDSs in pairwise genome comparisons, and in terms of gene repertoire, with the core genome accounting for ~80% of the genes in each genome. The pan-genome seems nevertheless "open" according to the scaling exponent of a power-law fitted on the rate of new gene discovery when genomes are added one-by one. Recombination is a key component of the evolutionary process of the species as seen in the high level of apparent homoplasy in the core genome. Using a Hidden Markov Model to delineate recombination tracts in pairs of closely related genomes, the average recombination tract length was estimated to ~4.0 Kbp and the typical ratio of the contributions of recombination and mutations to nucleotide level differentiation (r/m) was estimated to ~13. Within CC-ST10, evolutionary distances computed on non-recombined regions and comparisons between 22 isolates sampled up to 27 years apart suggest a most recent common ancestor in the second half of the nineteenth century in North America with subsequent diversification and transmission of this clonal complex coinciding with the worldwide expansion of rainbow trout farming. With the goal to promote the development of tools for the genetic manipulation of F. psychrophilum, a particular attention was also paid to plasmids. Their extraction and sequencing to completion revealed plasmid diversity that remained hidden to classical plasmid profiling due to size similarities. PMID- 29467747 TI - Metabolic Engineering for Enhanced Medium Chain Omega Hydroxy Fatty Acid Production in Escherichia coli. AB - Medium chain hydroxy fatty acids (HFAs) at omega-1, 2, or 3 positions (omega 1/2/3) are rare in nature but are attractive due to their potential applications in industry. They can be metabolically engineered in Escherichia coli, however, the current yield is low. In this study, metabolic engineering with P450BM3 monooxygenase was applied to regulate both the chain length and sub-terminal position of HFA products in E. coli, leading to increased yield. Five acyl-acyl carrier protein thioesterases from plants and bacteria were first evaluated for regulating the chain length of fatty acids. Co-expression of the selected thioesterase gene CcFatB1 with a fatty acid metabolism regulator fadR and monooxygenase P450BM3 boosted the production of HFAs especially omega-3-OH-C14:1, in both the wild type and fadD deficient strain. Supplementing renewable glycerol to reduce the usage of glucose as a carbon source further increased the HFAs production to 144 mg/L, representing the highest titer of such HFAs obtained in E. coli under the comparable conditions. This study illustrated an improved metabolic strategy for medium chain omega-1/2/3 HFAs production in E. coli. In addition, the produced HFAs were mostly secreted into culture media, which eased its recovery. PMID- 29467748 TI - Trace Metal Requirements and Interactions in Symbiodinium kawagutii. AB - Photosynthetic organisms need trace metals for various biological processes and different groups of microalgae have distinctive obligate necessities due to their respective biochemical requirements and ecological niches. We have previously shown that the dinoflagellate Symbiodinium kawagutii requires high concentrations of bioavailable Fe to achieve optimum growth. Here, we further explored the trace metal requirements of S. kawagutii with intensive focus on the effect of individual metal and its interaction with other divalent metals. We found that low Zn availability significantly decreases growth rates and results in elevated intracellular Mn, Co, Ni, and Fe quotas in the dinoflagellate. The results highlight the complex interaction among trace metals in S. kawagutii and suggest either metal replacement strategy to counter low Zn availability or enhanced uptake of other metals by non-specific divalent metal transporters. In this work, we also examined the Fe requirement of S. kawagutii using continuous cultures. We validated that 500 pM of Fe' was sufficient to support maximum cell density during steady state growth period either at 26 or 28 degrees C. This study shows that growth of S. kawagutii was limited by metal availability in the following order, Fe > Zn > Mn > Cu > Ni > Co. The fundamental information obtained for the free-living Symbiodinium shall provide insights into how trace metal availability, either from ambient seawater or hosts, affects growth and proliferation of symbiotic dinoflagellates and the interaction between symbiont and their hosts. PMID- 29467749 TI - Peptide Epimerization Machineries Found in Microorganisms. AB - D-Amino acid residues have been identified in peptides from a variety of eukaryotes and prokaryotes. In microorganisms, UDP-N-acetylmuramic acid pentapeptide (UDP-MurNAc-L-Ala-D-Glu-meso-diaminopimelate-D-Ala-D-Ala), a unit of peptidoglycan, is a representative. During its biosynthesis, D-Ala and D-Glu are generally supplied by racemases from the corresponding isomers. However, we recently identified a unique unidirectional L-Glu epimerase catalyzing the epimerization of the terminal L-Glu of UDP-MurNAc-L-Ala-L-Glu. Several such enzymes, introducing D-amino acid resides into peptides via epimerization, have been reported to date. This includes a L-Ala-D/L-Glu epimerase, which is possibly used during peptidoglycan degradation. In bacterial primary metabolisms, to the best of our knowledge, these two machineries are the only examples of peptide epimerization. However, a variety of peptides containing D-amino acid residues have been isolated from microorganisms as secondary metabolites. Their biosynthetic mechanisms have been studied and three different peptide epimerization machineries have been reported. The first is non-ribosomal peptide synthetase (NRPS). Excellent studies with dissected modules of gramicidin synthetase and tyrocidine synthetase revealed the reactions of the epimerization domains embedded in the enzymes. The obtained information is still utilized to predict epimerization domains in uncharacterized NRPSs. The second includes the biosynthetic enzymes of lantibiotics, which are ribosome-dependently supplied peptide antibiotics containing polycyclic thioether amino acids (lanthionines). A mechanism for the formation of the D-Ala moiety in lanthionine by two enzymes, dehydratases catalyzing the conversion of L-Ser into dehydroalanine and enzymes catalyzing nucleophilic attack of the thiol of cysteine into dehydroalanine, was clarified. Similarly, the formation of a D-Ala residue by reduction of the dehydroalanine residue was also reported. The last type of machinery includes radical-S-adenosylmethionine (rSAM)-dependent enzymes, which catalyze a variety of radical-mediated chemical transformations. In the biosynthesis of polytheonamide, a marine sponge-derived and ribosome-dependently supplied peptide composed of 48 amino acids, a rSAM enzyme (PoyD) is responsible for unidirectional epimerizations of multiple different amino acids in the precursor peptide. In this review, we briefly summarize the discovery and current mechanistic understanding of these peptide epimerization enzymes. PMID- 29467750 TI - The Peroxygenase Activity of the Aspergillus flavus Caleosin, AfPXG, Modulates the Biosynthesis of Aflatoxins and Their Trafficking and Extracellular Secretion via Lipid Droplets. AB - Aflatoxins (AF) are highly detrimental to human and animal health. We recently demonstrated that the Aspergillus flavus caleosin, AfPXG, had peroxygenase activity and mediated fungal development and AF accumulation. We now report the characterization of an AfPXG-deficient line using reference strain NRRL3357. The resulting fungal phenotype included a severe decrease in mycelium growth, failure to sporulate, and reduced AF production. Increasing cellular oxidative status by administration of hydrogen peroxide and cumene hydroperoxide did not restore the AfPXG-deficient phenotype, which suggests that AfPXG-deficiency is not directly related to oxidative stress. To investigate possible alternative roles of AfPXG, a gain of function approach was used to overexpress AfPXG, with the reporter gene Gfp, in an AfPXG-deficient line, termed AfPXG+ . The resulting phenotype included elevated numbers of stable lipid droplets (LDs) plus enhanced AF production. Highly purified LDs from AfPXG+ cultures sequestered AF and this ability was positively correlated with overall LD number. Site-specific mutagenesis of AfPXG to delete Histidine 85 (AfPXGHis85), a residue essential for its catalytic activity, or deletion of the putative LD targeting domain (AfPXGD126-140), showed that AfPXG-peroxygenase activity was required for AF biosynthesis and that integration of AF into LDs was required for their export via a LD-dependent pathway. Ectopic expression in fungal cells of the plant LD-associated protein, oleosin, also resulted in both additional LD accumulation and enhanced AF secretion. These results suggest that both fungal LDs and their associated caleosin proteins are intimately involved in the biosynthesis, trafficking, and secretion of AF. PMID- 29467751 TI - Photodynamic Vaccination of BALB/c Mice for Prophylaxis of Cutaneous Leishmaniasis Caused by Leishmania amazonensis. AB - Background: Photosensitizers (PS), like porphyrins and phthalocyanines (PC) are excitable by light to generate cytotoxic singlet oxygen and other reactive oxygen species in the presence of atmospheric O2. Photodynamic inactivation of Leishmania by this means renders them non-viable, but preserves their effective use as vaccines. Leishmania can be photo-inactivated after PS-sensitization by loading via their endocytic uptake of PC or endogenous induction of transgenic mutants with delta-aminolevulinate (ALA) to accumulate cytosolic uroporphyrin I (URO). Here, PS-sensitization and photo-inactivation of Leishmaniaamazonensis was further examined in vitro and in vivo for vaccination against cutaneous leishmaniasis (CL). Methods and Results:Leishmania amazonensis promastigotes were photodynamically inactivated in vitro by PC-loading followed by exposure to red light (1-2 J/cm2) or ALA-induction of uroporphyrinogenic transfectants to accumulate cytosolic URO followed by longwave UV exposure. When applied individually, both strategies of photodynamic inactivation were found to significantly, albeit incompletely abolish the MTT reduction activities of the promastigotes, their uptake by mouse bone marrow-derived macrophages in vitro and their infectivity to mouse ear dermis in vivo. Inactivation of Leishmania to completion by using a combination of both strategies was thus used for the sake of safety as whole-cell vaccines for immunization of BALB/c mice. Different cutaneous sites were assessed for the efficacy of such photodynamic vaccination in vivo. Each site was inoculated first with in vitro doubly PS-sensitized promastigotes and then spot-illuminated with white light (50 J/cm2) for their photo-inactivation in situ. Only in ear dermis parasites were photo-inactivated beyond detection. Mice were thus immunized once in the ear and challenged 3 weeks later at the tail base with virulent L. amazonensis. Prophylaxis was noted in mice photodynamically vaccinated with doubly photo-inactivated parasites, as indicated by a significant delay in the onset of lesion development and a substantial decrease in the parasite loads. Conclusion: Leishmania doubly PS sensitized and in situ photo-inactivated as described proved to be safe and effective when used for one-time immunization of ear dermis, as indicated by its significant protection of the inherently very susceptible BALB/c mice against CL. PMID- 29467752 TI - Compost Addition Enhanced Hyphal Growth and Sporulation of Arbuscular Mycorrhizal Fungi without Affecting Their Community Composition in the Soil. AB - Arbuscular mycorrhizal (AM) fungi form symbiotic associations with most crop plant species in agricultural ecosystems, and are conspicuously influenced by various agricultural practices. To understand the impact of compost addition on AM fungi, we examined effect of four compost rates (0, 11.25, 22.5, and 45 Mg/ha) on the abundance and community composition of AM fungi in seedling, flowering, and mature stage of soybean in a 1-year compost addition experiment system in Northeast China. Soybean [Glycine max (L.) Merrill] was used as test plant. Moderate (22.5 Mg/ha) and high (45 Mg/ha) levels of compost addition significantly increased AM root colonization and extraradical hyphal (ERH) density compared with control, whereas low (11.5 Mg/ha) level of compost addition did not cause significant increase in AM root colonization and ERH density. AM fungal spore density was significantly enhanced by all the compost rates compared with control. The temporal variations analysis revealed that, AM root colonization in seedling stage was significantly lower than in flowering and mature stage. Although AM fungal operational taxonomic unit richness and community composition was unaffected by compost addition, some abundant AM fungal species showed significantly different response to compost addition. In mature stage, Rhizophagus fasciculatum showed increasing trend along with compost addition gradient, whereas the opposite was observed with Paraglomus sp. In addition, AM fungal community composition exhibited significant temporal variation during growing season. Further analysis indicated that the temporal variation in AM fungal community only occurred in control treatment, but not in low, moderate, and high level of compost addition treatments. Our findings highlighted the significant effects of compost addition on AM growth and sporulation, and emphasized that growth stage is a stronger determinant than 1 year compost addition in shaping AM fungal community in black soil of Northeast China. PMID- 29467753 TI - The Plasma Kallikrein-Kininogen Pathway Is Critical in the Pathogenesis of Colitis in Mice. AB - The kallikrein-kinin system (KKS) consists of two serine proteases, prekallikrein (pKal) and factor XII (FXII), and a cofactor, high-molecular-weight kininogen (HK). Upon activation of the KKS, HK is cleaved to release bradykinin. Although the KKS is activated in humans and animals with inflammatory bowel disease (IBD), its role in the pathogenesis of IBD has not been characterized. In the present study, we determined the role of the KKS in the pathogenesis of IBD using mice that lack proteins involved in the KKS. In two colitis models, induced by dextran sulfate sodium (DSS) or 2,4,6-trinitrobenzene sulfonic acid (TNBS), mice deficient in HK, pKal, or bradykinin receptors displayed attenuated phenotypes, including body weight loss, disease activity index, colon length shortening, histological scoring, and colonic production of cytokines. Infiltration of neutrophils and inflammatory monocytes in the colonic lamina propria was reduced in HK-deficient mice. Reconstitution of HK-deficient mice through intravenous injection of HK recovered their susceptibility to DSS-induced colitis, increased IL-1beta levels in the colon tissue and bradykinin concentrations in plasma. In contrast to the phenotypes of other mice lacking other proteins involved in the KKS, mice lacking FXII had comparable colonic inflammation to that observed in wild-type mice. The concentration of bradykinin was significantly increased in the plasma of wild-type mice after DSS-induced colitis. In vitro analysis revealed that DSS-induced pKal activation, HK cleavage, and bradykinin plasma release were prevented by the absence of pKal or the inhibition of Kal. Unlike DSS, TNBS-induced colitis did not trigger HK cleavage. Collectively, our data strongly suggest that Kal, acting independently of FXII, contributes to experimental colitis by promoting bradykinin release from HK. PMID- 29467754 TI - Immune Repertoire Sequencing Using Molecular Identifiers Enables Accurate Clonality Discovery and Clone Size Quantification. AB - Unique molecular identifiers (MIDs) have been demonstrated to effectively improve immune repertoire sequencing (IR-seq) accuracy, especially to identify somatic hypermutations in antibody repertoire sequencing. However, evaluating the sensitivity to detect rare T cells and the degree of clonal expansion in IR-seq has been difficult due to the lack of knowledge of T cell receptor (TCR) RNA molecule copy number and a generalized approach to estimate T cell clone size from TCR RNA molecule quantification. This limited the application of TCR repertoire sequencing (TCR-seq) in clinical settings, such as detecting minimal residual disease in lymphoid malignancies after treatment, evaluating effectiveness of vaccination and assessing degree of infection. Here, we describe using an MID Clustering-based IR-Seq (MIDCIRS) method to quantitatively study TCR RNA molecule copy number and clonality in T cells. First, we demonstrated the necessity of performing MID sub-clustering to eliminate erroneous sequences. Further, we showed that MIDCIRS enables a sensitive detection of a single cell in as many as one million naive T cells and an accurate estimation of the degree of T cell clonal expression. The demonstrated accuracy, sensitivity, and wide dynamic range of MIDCIRS TCR-seq provide foundations for future applications in both basic research and clinical settings. PMID- 29467755 TI - Leptin Mediates In Vivo Neutrophil Migration: Involvement of Tumor Necrosis Factor-Alpha and CXCL1. AB - Leptin directly activates macrophages and lymphocytes, but the role of leptin in neutrophil activation and migration is still controversial. Here, we investigate the in vivo mechanisms of neutrophil migration induced by leptin. The intraperitoneal injection of leptin (1 mg/kg) induces a time- and concentration dependent neutrophil influx. We did not observe the enhancement of lipid bodies/droplets in neutrophils, after leptin treatment, as we had observed previously in peritoneal macrophages. The participation of leukotriene B4 (LTB4) in neutrophil recruitment triggered by leptin was investigated using different strategies. Leptin-induced neutrophil recruitment occurs both in the absence of 5 lipoxygenase activity in 5-lipoxygenase (5-LO)-/- mice and after the administration of either 5-LO inhibitor (Zileuton) or the LTB4 receptor antagonist (U-75302). Moreover, no direct induction of LTB4 by leptin could be observed. Neutrophil influx could not be prevented by the mammalian target of rapamycin (mTOR) inhibitor, rapamycin, contrasting with the leptin-induced signaling for lipid body formation in macrophage that is mTOR-dependent. Leptin administration led to tumor necrosis factor-alpha (TNFalpha) production by the peritoneal cells both in vivo and in vitro. In addition, neutrophil recruitment was inhibited in tumor necrosis factor receptor 1 (TNFR1-/-) mice, indicating a role for TNF in leptin-induced neutrophil recruitment to the peritoneal cavity. Leptin-induced neutrophil influx was PI3Kgamma-dependent, as it was absent in PI3Kgamma-/- mice. Accordingly, leptin induced the peritoneal cells to produce CXCL1, both in vivo and in vitro, and the neutrophil influx was ablated after using an antibody against CXCL1. Our results establish TNFalpha/TNFR1- and CXCL1 dependent signaling as important pathways for leptin-induced neutrophil migration in vivo. PMID- 29467756 TI - The Macrophage Mannose Receptor Regulate Mannan-Induced Psoriasis, Psoriatic Arthritis, and Rheumatoid Arthritis-Like Disease Models. AB - The injection of mannan into mice can result in the development of psoriasis (Ps) and psoriatic arthritis (PsA), whereas co-injection with antibodies toward collagen type II leads to a chronic rheumatoid-like arthritis. The critical event in all these diseases is mannan-mediated activation of macrophages, causing more severe disease if the macrophages are deficient in neutrophil cytosolic factor 1 (Ncf1), i.e., lack the capacity to make a reactive oxygen species (ROS) burst. In this study, we investigated the role of one of the receptors binding mannan; the macrophage mannose receptor (MR, CD206). MR is a C-type lectin present on myeloid cells and lymphatics. We found that mice deficient in MR expression had more severe mannan-induced Ps, PsA as well as rheumatoid-like arthritis. Interestingly, the MR-mediated protection was partly lost in Ncf1 mutated mice and was associated with an type 2 macrophage expansion. In conclusion, these results show that MR protects against a pathogenic inflammatory macrophage response induced by mannan and is associated with induction of ROS. PMID- 29467757 TI - Genetic Regulation of Guanylate-Binding Proteins 2b and 5 during Leishmaniasis in Mice. AB - Interferon-induced GTPases [guanylate-binding proteins (GBPs)] play an important role in inflammasome activation and mediate innate resistance to many intracellular pathogens, but little is known about their role in leishmaniasis. We therefore studied expression of Gbp2b/Gbp1 and Gbp5 mRNA in skin, inguinal lymph nodes, spleen, and liver after Leishmania major infection and in uninfected controls. We used two different groups of related mouse strains: BALB/c, STS, and CcS-5, CcS-16, and CcS-20 that carry different combinations of BALB/c and STS genomes, and strains O20, C57BL/10 (B10) and B10.O20, OcB-9, and OcB-43 carrying different combinations of O20 and B10 genomes. The strains were classified on the basis of size and number of infection-induced skin lesions as highly susceptible (BALB/c, CcS-16), susceptible (B10.O20), intermediate (CcS-20), and resistant (STS, O20, B10, OcB-9, OcB-43). Some uninfected strains differed in expression of Gbp2b/Gbp1 and Gbp5, especially of Gbp2b/Gbp1 in skin. Uninfected BALB/c and STS did not differ in their expression, but in CcS-5, CcS-16, and CcS-20, which all carry BALB/c-derived Gbp gene-cluster, expression of Gbp2b/Gbp1 exceeds that of both parents. These data indicate trans-regulation of Gbps. Infection resulted in approximately 10* upregulation of Gbp2b/Gbp1 and Gbp5 mRNAs in organs of both susceptible and resistant strains, which was most pronounced in skin. CcS-20 expressed higher level of Gbp2b/Gbp1 than both parental strains in skin, whereas CcS-16 expressed higher level of Gbp2b/Gbp1 than both parental strains in skin and liver. This indicates a trans-regulation present in infected mice CcS-16 and CcS-20. Immunostaining of skin of five strains revealed in resistant and intermediate strains STS, CcS-5, O20, and CcS-20 tight co-localization of Gbp2b/Gbp1 protein with most L. major parasites, whereas in the highly susceptible strain, BALB/c most parasites did not associate with Gbp2b/Gbp1. In conclusion, expression of Gbp2b/Gbp1 and Gbp5 was increased even in organs of clinically asymptomatic resistant mice. It suggests a hidden inflammation, which might contribute to control of persisting parasites. This is supported by the co localization of Gbpb2/Gbp1 protein and L. major parasites in skin of resistant and intermediate but not highly susceptible mice. PMID- 29467758 TI - Predicting Early Viral Control under Direct-Acting Antiviral Therapy for Chronic Hepatitis C Virus Using Pretreatment Immunological Markers. AB - Recent introduction of all-oral direct-acting antiviral (DAA) treatment has revolutionized care of patients with chronic hepatitis C virus (HCV) infection. Regrettably, the high cost of DAA treatment is burdensome for healthcare systems and may be prohibitive for some patients who would otherwise benefit. Understanding how patient-related factors influence individual responses to DAA treatment may lead to more efficient prescribing. In this observational study, patients with chronic HCV infection were comprehensively monitored by flow cytometry to identify pretreatment immunological variables that predicted HCV RNA negativity within 4 weeks of commencing DAA treatment. Twenty-three patients [genotype 1a (n = 10), 1b (n = 9), and 3 (n = 4)] were treated with daclatasvir plus sofosbuvir (SOF) (n = 15), ledipasvir plus SOF (n = 4), or ritonavir-boosted paritaprevir, ombitasvir, and dasabuvir (n = 4). DAA treatment most prominently altered the distribution of CD8+ memory T cell subsets. Knowing only pretreatment frequencies of CD3+ and naive CD8+ T cells allowed correct classification of 83% of patients as "fast" (HCV RNA-negative by 4 weeks) or "slow" responders. In a prospective cohort, these parameters correctly classified 90% of patients. Slow responders exhibited higher frequencies of CD3+ T cells, CD8+ TEM cells, and CD5high CD27- CD57+ CD8+ chronically activated T cells, which is attributed to bystander hyperactivation of virus-non-specific CD8+ T cells. Taken together, non specific, systemic CD8+ T cell activation predicted a longer time to viral clearance. This discovery allows pretreatment identification of individuals who may not require a full 12-week course of DAA therapy; in turn, this could lead to individualized prescribing and more efficient resource allocation. PMID- 29467759 TI - Magnolol Alleviates Inflammatory Responses and Lipid Accumulation by AMP Activated Protein Kinase-Dependent Peroxisome Proliferator-Activated Receptor alpha Activation. AB - Magnolol (MG) is a kind of lignin isolated from Magnolia officinalis, which serves several different biological functions, such as antifungal, anticancer, antioxidant, and hepatoprotective functions. This study aimed to evaluate the protective effect of MG against oleic acid (OA)-induced hepatic steatosis and inflammatory damage in HepG2 cells and in a tyloxapol (Ty)-induced hyperlipidemia mouse model. Our findings indicated that MG can effectively inhibit OA-stimulated tumor necrosis factor alpha (TNF-alpha) secretion, reactive oxygen species generation, and triglyceride (TG) accumulation. Further study manifested that MG significantly suppressed OA-activated mitogen-activated protein kinase (MAPK) and nuclear factor-kappa B (NF-kappaB) signaling pathways and that these inflammatory responses can be negated by pretreatment with inhibitors of extracellular regulated protein kinase and c-Jun N-terminal kinase (U0126 and SP600125, respectively). In addition, MG dramatically upregulated peroxisome proliferator activated receptor alpha (PPARalpha) translocation and reduced sterol regulatory element-binding protein 1c (SREBP-1c) protein synthesis and excretion, both of which are dependent upon the phosphorylation of adenosine monophosphate (AMP) activated protein kinase (AMPK), acetyl-CoA carboxylase, and AKT kinase (AKT). However, MG suspended the activation of PPARalpha expression and was thus blocked by pretreatment with LY294002 and compound c (specific inhibitors of AKT and AMPK). Furthermore, MG clearly alleviated serum TG and total cholesterol release; upregulated AKT, AMPK, and PPARalpha expression; suppressed SREBP-1c generation; and alleviated hepatic steatosis and dyslipidemia in Ty-induced hyperlipidemia mice. Taken together, these results suggest that MG exerts protective effects against steatosis, hyperlipidemia, and the underlying mechanism, which may be closely associated with AKT/AMPK/PPARalpha activation and MAPK/NF-kappaB/SREBP-1c inhibition. PMID- 29467761 TI - Establishment of the Reference Intervals of Lymphocyte Function in Healthy Adults Based on IFN-gamma Secretion Assay upon Phorbol-12-Myristate-13-Acetate/Ionomycin Stimulation. AB - The function of lymphocytes is the key to reflect the immune status of hosts. Evaluation of lymphocyte function is a useful tool to monitor the effect of immunosuppressive treatment and predict the prognosis of immune-mediated diseases (e.g., cancer, autoimmune diseases, and infectious diseases). As the lymphocytes have various activities, such as activation, cytotoxicity, and cytokine secretion, it is a challenge to evaluate the function of lymphocytes in clinical practice and the reference intervals (RIs) of lymphocyte function are rarely reported. The present study showed that the secretion of IFN-gamma was well correlated with the activation, chemotaxis, and cytotoxicity of CD4+, CD8+ T cells, and NK cells, which suggests that IFN-gamma production can be used as a symbol of lymphocyte function. We therefore created a simple method to detect the function of CD4+, CD8+ T cells, and NK cells simultaneously according to IFN gamma secretion by using whole blood instead of peripheral blood mononuclear cells. We further established the RIs of lymphocyte function (CD4+ T cells: 15.31 34.98%; CD8+ T cells: 26.11-66.59%; NK cells: 39.43-70.79%) in healthy adults. This method showed good reproducibility for the evaluation of lymphocyte function. The established RIs were suitable for use in other centers based on the validation data. We also validated the RIs in individuals with different immune status, and the results showed that kidney transplant recipients and infants (0-1 year) had a decreased lymphocyte function, whereas T cells in systemic lupus erythematosus patients exhibited an opposite trend. Overall, we have successfully established the RIs of lymphocyte function in healthy adults in a simple way, which might be of important clinical value in the diagnosis, monitoring, and prognosis of immune-related diseases. PMID- 29467760 TI - MicroRNA Regulation of Host Immune Responses following Fungal Exposure. AB - Fungal bioaerosols are ubiquitous in the environment and human exposure can result in a variety of health effects ranging from systemic, subcutaneous, and cutaneous infections to respiratory morbidity including allergy, asthma, and hypersensitivity pneumonitis. Recent research has focused on the role of microRNAs (miRNAs) following fungal exposure and is overlooked, yet important, group of regulators capable of influencing fungal immune responses through a variety of cellular mechanisms. These small non-coding ribose nucleic acids function to regulate gene expression at the post-transcriptional level and have been shown to participate in multiple disease pathways including cancer, heart disease, apoptosis, as well as immune responses to microbial hazards and occupational allergens. Recent animal model studies have characterized miRNAs following the exposure to inflammatory stimuli. Studies focused on microbial exposure, including bacterial infections, as well as exposure to different allergens have shown miRNAs, such as miR-21, miR-146, miR-132, miR-155, and the let-7 family members, to be involved in immune and inflammatory responses. Interestingly, the few studies have assessed that the miRNA profiles following fungal exposure have identified the same critical miRNAs that have been characterized in other inflammatory-mediated and allergy-induced experimental models. Review of available in vitro, animal and human studies of exposures to Aspergillus fumigatus, Candida albicans, Cryptococcus neoformans, Paracoccidioides brasiliensis, and Stachybotrys chartarum identified several miRNAs that were shared between responses to these species including miR-125 a/b (macrophage polarization/activation), miR-132 [toll-like receptor (TLR)2-mediated signaling], miR-146a (TLR mediated signaling, alternative macrophage activation), and miR-29a/b (natural killer cell function, C-leptin signaling, inhibition of Th1 immune response). Although these datasets provide preliminary insight into the role of miRNAs in fungal exposed models, interpretation of miRNA datasets can be challenging for researchers. To assist in navigating this rapidly evolving field, the aim of this review is to describe miRNAs in the framework of host recognition mechanisms and provide initial insight into the regulatory pathways in response to fungal exposure. PMID- 29467762 TI - Inositol-Requiring Enzyme 1-Mediated Downregulation of MicroRNA (miR)-146a and miR-155 in Primary Dermal Fibroblasts across Three TNFRSF1A Mutations Results in Hyperresponsiveness to Lipopolysaccharide. AB - Tumor necrosis factor (TNF)-receptor-associated periodic fever syndrome (TRAPS) is a rare monogenic autoinflammatory disorder characterized by mutations in the TNFRSF1A gene, causing TNF-receptor 1 (TNFR1) misfolding, increased cellular stress, activation of the unfolded protein response (UPR), and hyperresponsiveness to lipopolysaccharide (LPS). Both microRNA (miR)-146a and miR 155 provide negative feedback for LPS-toll-like receptor 2/4 signaling and cytokine production, through regulation of nuclear factor kappa B (NF-kappaB). In this study, we hypothesized that proinflammatory cytokine signaling in TRAPS downregulates these two miRs, resulting in LPS-induced hyperresponsiveness in TRAPS dermal fibroblasts (DFs), irrespective of the underlying genetic mutation. Primary DF were isolated from skin biopsies of TRAPS patients and healthy controls (HC). TNFR1 cell surface expression was measured using immunofluorescence. DF were stimulated with LPS, interleukin (IL)-1beta, thapsigargin, or TNF, with and without inositol-requiring enzyme 1 (IRE1) inhibitor (4u8C), following which miR-146a and miR-155 expression was measured by RT-qPCR. IL-1beta, IL-6, and TNF secretion was measured by enzyme-linked immunosorbent assays, and baseline expression of 384 different miRs was assessed using microfluidics assays. TNFR1 was found to be expressed on the surface of HC DF but expression was deficient in all samples with TRAPS-associated mutations. HC DF showed significant dose-dependent increases in both miR-146a and miR-155 expression levels in response to LPS; however, TRAPS DF failed to upregulate either miR-146a or miR-155 under the same conditions. This lack of miR-146a and miR-155 upregulation was associated with increased proinflammatory cytokine production in TRAPS DF in response to LPS challenge, which was abrogated by 4u8C. Incubation of HC DF with IL-1beta led to downregulation of miR-146a and miR-155 expression, which was dependent on IRE1 enzyme. We observed global dysregulation of hundreds of other miRs at baseline in the TRAPS DF. In summary, these data suggest a mechanism whereby IL-1beta, produced in response to activation of the UPR in TRAPS DF, downregulates miR-146a and miR-155, by inducing IRE1-dependent cleavage of both these miRs, thereby impairing negative regulation of NF-kappaB and increasing proinflammatory cytokine production. PMID- 29467763 TI - Functional Role of Transient Receptor Potential Channels in Immune Cells and Epithelia. AB - Transient receptor potential (TRP) ion channels are widely expressed in several tissues throughout the mammalian organism. Originally, TRP channel physiology was focusing on its fundamental meaning in sensory neuronal function. Today, it is known that activation of several TRP ion channels in peptidergic neurons does not only result in neuropeptide release and consecutive neurogenic inflammation. Growing evidence demonstrates functional extra-neuronal TRP channel expression in immune and epithelial cells with important implications for mucosal immunology. TRP channels maintain intracellular calcium homeostasis to regulate various functions in the respective cells such as nociception, production and release of inflammatory mediators, phagocytosis, and cell migration. In this review, we provide an overview about TRP-mediated effects in immune and epithelial cells with an emphasis on mucosal immunology of the gut. Crosstalk between neurons, epithelial cells, and immune cells induced by activation of TRP channels orchestrates the immunologic response. Understanding of its molecular mechanisms paves the way to novel clinical approaches for the treatment of various inflammatory disorders including IBD. PMID- 29467764 TI - Propionibacterium acnes Enhances the Immunogenicity of HIVBr18 Human Immunodeficiency Virus-1 Vaccine. AB - Immunization of BALB/c mice with HIVBr18, a DNA vaccine containing 18 CD4+ T cell epitopes from human immunodeficiency virus (HIV), induced specific CD4+ and CD8+ T cell responses in a broad, polyfunctional and persistent manner. With the aim of increasing the immunogenicity of this vaccine, the effect of Propionibacterium acnes as an adjuvant was evaluated. The adjuvant effects of this bacterium have been extensively demonstrated in both experimental and clinical settings. Herein, administration of two doses of HIVBr18, in the presence of P. acnes, increased the proliferation of HIV-1-specific CD4+ and CD8+ T lymphocytes, the polyfunctional profile of CD4+ T cells, the production of IFN-gamma, and the number of recognized vaccine-encoded peptides. One of the bacterial components responsible for most of the adjuvant effects observed was a soluble polysaccharide extracted from the P. acnes cell wall. Furthermore, within 10 weeks after immunization, the proliferation of specific T cells and production of IFN-gamma were maintained when the whole bacterium was administered, demonstrating a greater effect on the longevity of the immune response by P. acnes. Even with fewer immunization doses, P. acnes was found to be a potent adjuvant capable of potentiating the effects of the HIVBr18 vaccine. Therefore, P. acnes may be a potential adjuvant to aid this vaccine in inducing immunity or for therapeutic use. PMID- 29467765 TI - Pathogenic Bacterium Acinetobacter baumannii Inhibits the Formation of Neutrophil Extracellular Traps by Suppressing Neutrophil Adhesion. AB - Hospital-acquired infections caused by Acinetobacter baumannii have become problematic because of high rates of drug resistance. A. baumannii is usually harmless, but it may cause infectious diseases in an immunocompromised host. Although neutrophils are the key players of the initial immune response against bacterial infection, their interactions with A. baumannii remain largely unknown. A new biological defense mechanism, termed neutrophil extracellular traps (NETs), has been attracting attention. NETs play a critical role in bacterial killing by bacterial trapping and inactivation. Many pathogenic bacteria have been reported to induce NET formation, while an inhibitory effect on NET formation is rarely reported. In the present study, to assess the inhibition of NET formation by A. baumannii, bacteria and human neutrophils were cocultured in the presence of phorbol 12-myristate 13-acetate (PMA), and NET formation was evaluated. NETs were rarely observed during the coculture despite neutrophil PMA stimulation. Furthermore, A. baumannii prolonged the lifespan of neutrophils by inhibiting NET formation. The inhibition of NET formation by other bacteria was also investigated. The inhibitory effect was only apparent with live A. baumannii cells. Finally, to elucidate the mechanism of this inhibition, neutrophil adhesion was examined. A. baumannii suppressed the adhesion ability of neutrophils, thereby inhibiting PMA-induced NET formation. This suppression of cell adhesion was partly due to suppression of the surface expression of CD11a in neutrophils. The current study constitutes the first report on the inhibition of NET formation by a pathogenic bacterium, A. baumannii, and prolonging the neutrophil lifespan. This novel pathogenicity to inhibit NET formation, thereby escaping host immune responses might contribute to a development of new treatment strategies for A. baumannii infections.

PMID- 29467767 TI - Identification of Casz1 as a Regulatory Protein Controlling T Helper Cell Differentiation, Inflammation, and Immunity. AB - While T helper (Th) cells play a crucial role in host defense, an imbalance in Th effector subsets due to dysregulation in their differentiation and expansion contribute to inflammatory disorders. Here, we show that Casz1, whose function is previously unknown in CD4+ T cells, coordinates Th differentiation in vitro and in vivo. Casz1 deficiency in CD4+ T cells lowers susceptibility to experimental autoimmune encephalomyelitis, consistent with the reduced frequency of Th17 cells, despite an increase in Th1 cells in mice. Loss of Casz1 in the context of mucosal Candida infection severely impairs Th17 and Treg responses, and lowers the ability of the mice to clear the secondary infection. Importantly, in both the models, absence of Casz1 causes a significant diminution in IFN-gamma+IL-17A+ double-positive inflammatory Th17 cells (Th1* cells) in tissues in vivo. Transcriptome analyses of CD4+ T cells lacking Casz1 show a signature consistent with defective Th17 differentiation. With regards to Th17 differentiation, Casz1 limits repressive histone marks and enables acquisition of permissive histone marks at Rorc, Il17a, Ahr, and Runx1 loci. Taken together, these data identify Casz1 as a new Th plasticity regulator having important clinical implications for autoimmune inflammation and mucosal immunity. PMID- 29467768 TI - Cytokine Networks between Innate Lymphoid Cells and Myeloid Cells. AB - Innate lymphoid cells (ILCs) are an essential component of the innate immune system in vertebrates. They are developmentally rooted in the lymphoid lineage and can diverge into at least three transcriptionally distinct lineages. ILCs seed both lymphoid and non-lymphoid tissues and are locally self-maintained in tissue-resident pools. Tissue-resident ILCs execute important effector functions making them key regulator in tissue homeostasis, repair, remodeling, microbial defense, and anti-tumor immunity. Similar to T lymphocytes, ILCs possess only few sensory elements for the recognition of non-self and thus depend on extrinsic cellular sensory elements residing within the tissue. Myeloid cells, including mononuclear phagocytes (MNPs), are key sentinels of the tissue and are able to translate environmental cues into an effector profile that instructs lymphocyte responses. The adaptation of myeloid cells to the tissue state thus influences the effector program of ILCs and serves as an example of how environmental signals are integrated into the function of ILCs via a tissue-resident immune cell cross talks. This review summarizes our current knowledge on the role of myeloid cells in regulating ILC functions and discusses how feedback communication between ILCs and myeloid cells contribute to stabilize immune homeostasis in order to maintain the healthy state of an organ. PMID- 29467770 TI - Cytokines Stimulate the Release of Microvesicles from Myeloid Cells Independently from the P2X7 Receptor/Acid Sphingomyelinase Pathway. AB - Microvesicles (MVs) are membrane particles of 200-500 nm released by all cell types constitutively. MVs of myeloid origin are found increased in the cerebrospinal fluid (CSF) of patients suffering from neuroinflammatory disorders, although the factors triggering their production have never been defined. Here, we report that both pro- and anti-inflammatory cytokines, specifically interferon gamma and interleukin-4, are equally able to stimulate the production of MVs from microglia cells and monocytes. Additionally, we found this process to be independent from the best characterized molecular pathway so far described for membrane shedding, which is centered on the purinergic receptor P2X7, whose activation by high concentrations of extracellular ATP (exATP) results in membrane blebbing operated by the secreted enzyme acid sphingomyelinase (ASMase). Moreover, a potent inhibitor of ASMase, injected in a mouse model of multiple sclerosis, failed to reduce the number of MVs in their CSF. This suggests that cytokines, rather than exATP, may exert a long-term control of MV production in the context of chronic inflammation, where both pro- and anti-inflammatory factors play coordinated roles. PMID- 29467769 TI - CD137+CD154- Expression As a Regulatory T Cell (Treg)-Specific Activation Signature for Identification and Sorting of Stable Human Tregs from In Vitro Expansion Cultures. AB - Regulatory T cells (Tregs) are an attractive therapeutic tool for several different immune pathologies. Therapeutic Treg application often requires prolonged in vitro culture to generate sufficient Treg numbers or to optimize their functionality, e.g., via genetic engineering of their antigen receptors. However, purity of clinical Treg expansion cultures is highly variable, and currently, it is impossible to identify and separate stable Tregs from contaminating effector T cells, either ex vivo or after prior expansion. This represents a major obstacle for quality assurance of expanded Tregs and raises significant safety concerns. Here, we describe a Treg activation signature that allows identification and sorting of epigenetically imprinted Tregs even after prolonged in vitro culture. We show that short-term reactivation resulted in expression of CD137 but not CD154 on stable FoxP3+ Tregs that displayed a demethylated Treg-specific demethylated region, high suppressive potential, and lack of inflammatory cytokine expression. We also applied this Treg activation signature for rapid testing of chimeric antigen receptor functionality in human Tregs and identified major differences in the signaling requirements regarding CD137 versus CD28 costimulation. Taken together, CD137+CD154- expression emerges as a universal Treg activation signature ex vivo and upon in vitro expansion allowing the identification and isolation of epigenetically stable antigen activated Tregs and providing a means for their rapid functional testing in vitro. PMID- 29467771 TI - Association of microRNAs with Types of Leaf Curvature in Brassica rapa. AB - Many vegetable crops of Brassica rapa are characterized by their typical types of leaf curvature. Leaf curvature in the right direction and to the proper degree is important for the yield and quality of green vegetable products, when cultivated under stress conditions. Recent research has unveiled some of the roles of miRNAs in Brassica crops such as how they regulate the timing of leafy head initiation and shape of the leafy head. However, the molecular mechanism underlying the variability in leaf curvature in B. rapa remains unclear. We tested the hypothesis that the leaf curvature of B. rapa is affected by miRNA levels. On the basis of leaf phenotyping, 56 B. rapa accessions were classified into five leaf curvature types, some of which were comparable to miRNA mutants of Arabidopsis thaliana in phenotype. Higher levels of miR166 and miR319a expression were associated with downward curvature and wavy margins, respectively. Overexpression of the Brp-MIR166g-1 gene caused rosette leaves to change from flat to downward curving and folding leaves to change from upward curving to flat, leading to the decrease in the number of incurved leaves and size of the leafy head. Our results reveal that miRNAs affect the types of leaf curvature in B. rapa. These findings provide insight into the relationship between miRNAs and variation in leaf curvature. PMID- 29467772 TI - Genetic and Genomic Tools to Asssist Sugar Beet Improvement: The Value of the Crop Wild Relatives. AB - Sugar beet (Beta vulgaris L. ssp. vulgaris) is one of the most important European crops for both food and sugar production. Crop improvement has been developed to enhance productivity, sugar content or other breeder's desirable traits. The introgression of traits from Crop Wild Relatives (CWR) has been done essentially for lessening biotic stresses constraints, namely using Beta and Patellifolia species which exhibit disease resistance characteristics. Several studies have addressed crop-to-wild gene flow, yet, for breeding programs genetic variability associated with agronomically important traits remains unexplored regarding abiotic factors. To accomplish such association from phenotype-to-genotype, screening for wild relatives occurring in habitats where selective pressures are in play (i.e., populations in salt marshes for salinity tolerance; populations subjected to pathogen attacks and likely evolved resistance to pathogens) are the most appropriate streamline to identify causal genetic information. By selecting sugar beet CWR species based on genomic tools, rather than random variations, is a promising but still seldom explored route toward the development of improved crops. In this perspective, a viable streamline for sugar beet improvement is proposed through the use of different genomic tools by recurring to sugar beet CWRs and focusing on agronomic traits associated with abiotic stress tolerance. Overall, identification of genomic and epigenomic landscapes associated to adaptive ecotypes, along with the cytogenetic and habitat characterization of sugar beet CWR, will enable to identify potential hotspots for agrobiodiversity of sugar beet crop improvement toward abiotic stress tolerance. PMID- 29467773 TI - Characterization of Novel Plant Symbiosis Mutants Using a New Multiple Gene Expression Reporter Sinorhizobium meliloti Strain. AB - The formation of nitrogen fixing root nodules by Medicago truncatula and Sinorhizobium meliloti requires communication between both organisms and coordinated differentiation of plant and bacterial cells. After an initial signal exchange, the bacteria invade the tissue of the growing nodule via plant-derived tubular structures, called infection threads. The bacteria are released from the infection threads into invasion-competent plant cells, where they differentiate into nitrogen-fixing bacteroids. Both organisms undergo dramatic transcriptional, metabolic and morphological changes during nodule development. To identify plant processes that are essential for the formation of nitrogen fixing nodules after nodule development has been initiated, large scale mutageneses have been conducted to discover underlying plant symbiosis genes. Such screens yield numerous uncharacterized plant lines with nitrogen fixation deficient nodules. In this study, we report construction of a S. meliloti strain carrying four distinct reporter constructs to reveal stages of root nodule development. The strain contains a constitutively expressed lacZ reporter construct; a PexoY-mTFP fusion that is expressed in infection threads but not in differentiated bacteroids; a PbacA-mcherry construct that is expressed in infection threads and during bacteroid differentiation; and a PnifH-uidA construct that is expressed during nitrogen fixation. We used this strain together with fluorescence microscopy to study nodule development over time in wild type nodules and to characterize eight plant mutants from a fast neutron bombardment screen. Based on the signal intensity and the localization patterns of the reporter genes, we grouped mutants with similar phenotypes and placed them in a developmental context. PMID- 29467774 TI - Genome-Based Prediction of Time to Curd Induction in Cauliflower. AB - The development of cauliflower (Brassica oleracea var. botrytis) is highly dependent on temperature due to vernalization requirements, which often causes delay and unevenness in maturity during months with warm temperatures. Integrating quantitative genetic analyses with phenology modeling was suggested to accelerate breeding strategies toward wide-adaptation cauliflower. The present study aims at establishing a genome-based model simulating the development of doubled haploid (DH) cauliflower lines to predict time to curd induction of DH lines not used for model parameterization and test hybrids derived from the bi parental cross. Leaf appearance rate and the relation between temperature and thermal time to curd induction were examined in greenhouse trials on 180 DH lines at seven temperatures. Quantitative trait loci (QTL) analyses carried out on model parameters revealed ten QTL for leaf appearance rate (LAR), five for the slope and two for the intercept of linear temperature-response functions. Results of the QTL-based phenology model were compared to a genomic selection (GS) model. Model validation was carried out on data comprising four field trials with 72 independent DH lines, 160 hybrids derived from the parameterization set, and 34 hybrids derived from independent lines of the population. The QTL model resulted in a moderately accurate prediction of time to curd induction (R2 = 0.42-0.51) while the GS model generated slightly better results (R2 = 0.52-0.61). Predictions of time to curd induction of test hybrids from independent DH lines were less precise with R2 = 0.40 for the QTL and R2 = 0.48 for the GS model. Implementation of juvenile-to-adult phase transition is proposed for model improvement. PMID- 29467775 TI - Intra-annual Dynamics of Xylem Formation in Liquidambar formosana Subjected to Canopy and Understory N Addition. AB - Increasing N deposition caused by intensive anthropogenic activities is expected to affect forest growth. However, the effects of N deposition on trees are still controversial due to the wide variability in results and experimental methods used. We conducted an experiment involving both canopy and understory N addition to investigate the effects of N-addition on intra-annual xylem formation of Chinese sweetgum (Liquidambar formosana) in a warm-temperate forest of Central China. Since 2013, 50 kg N ha-1 year-1 (2.5 times the current natural N deposition) was applied monthly from April to December. In 2014 and 2015, the timing and dynamics of xylem formation were monitored weekly during March December by microcoring the stems of control and treated trees. Similar dynamics of wood formation were observed between canopy and understory N addition. Xylem formation of all the experimental trees started in March and lasted for 119-292 days. Compared to the control, no change was observed in the timing and dynamics of wood formation in N-treated trees. Tree ring-width ranged between 1701 and 4774 MUm, with a rate of xylem production of 10.52-26.64 MUm day-1. The radial growth of trees was not modified by the treatments. Our findings suggest that short-term N addition is unable to affect the dynamics of xylem formation in Chinese sweetgum in Central China. The effects of N on tree growth observed in previous studies might be related to the duration of the experiment or the imbalance between the amount of natural deposition and N added during treatments. PMID- 29467777 TI - Interannual Change Detection of Mediterranean Seagrasses Using RapidEye Image Time Series. AB - Recent research studies have highlighted the decrease in the coverage of Mediterranean seagrasses due to mainly anthropogenic activities. The lack of data on the distribution of these significant aquatic plants complicates the quantification of their decreasing tendency. While Mediterranean seagrasses are declining, satellite remote sensing technology is growing at an unprecedented pace, resulting in a wealth of spaceborne image time series. Here, we exploit recent advances in high spatial resolution sensors and machine learning to study Mediterranean seagrasses. We process a multispectral RapidEye time series between 2011 and 2016 to detect interannual seagrass dynamics in 888 submerged hectares of the Thermaikos Gulf, NW Aegean Sea, Greece (eastern Mediterranean Sea). We assess the extent change of two Mediterranean seagrass species, the dominant Posidonia oceanica and Cymodocea nodosa, following atmospheric and analytical water column correction, as well as machine learning classification, using Random Forests, of the RapidEye time series. Prior corrections are necessary to untangle the initially weak signal of the submerged seagrass habitats from satellite imagery. The central results of this study show that P. oceanica seagrass area has declined by 4.1%, with a trend of -11.2 ha/yr, while C. nodosa seagrass area has increased by 17.7% with a trend of +18 ha/yr throughout the 5-year study period. Trends of change in spatial distribution of seagrasses in the Thermaikos Gulf site are in line with reported trends in the Mediterranean. Our presented methodology could be a time- and cost-effective method toward the quantitative ecological assessment of seagrass dynamics elsewhere in the future. From small meadows to whole coastlines, knowledge of aquatic plant dynamics could resolve decline or growth trends and accurately highlight key units for future restoration, management, and conservation. PMID- 29467776 TI - Genome-Wide Association Analyses Identify QTL Hotspots for Yield and Component Traits in Durum Wheat Grown under Yield Potential, Drought, and Heat Stress Environments. AB - Understanding the genetic bases of economically important traits is fundamentally important in enhancing genetic gains in durum wheat. In this study, a durum panel of 208 lines (comprised of elite materials and exotics from the International Maize and Wheat Improvement Center gene bank) were subjected to genome wide association study (GWAS) using 6,211 DArTseq single nucleotide polymorphisms (SNPs). The panel was phenotyped under yield potential (YP), drought stress (DT), and heat stress (HT) conditions for 2 years. Mean yield of the panel was reduced by 72% (to 1.64 t/ha) under HT and by 60% (to 2.33 t/ha) under DT, compared to YP (5.79 t/ha). Whereas, the mean yield of the panel under HT was 30% less than under DT. GWAS identified the largest number of significant marker-trait associations on chromosomes 2A and 2B with p-values 10-06 to 10-03 and the markers from the whole study explained 7-25% variation in the traits. Common markers were identified for stress tolerance indices: stress susceptibility index, stress tolerance, and stress tolerance index estimated for the traits under DT (82 cM on 2B) and HT (68 and 83 cM on 3B; 25 cM on 7A). GWAS of irrigated (YP and HT combined), stressed (DT and HT combined), combined analysis of three environments (YP + DT + HT), and its comparison with trait per se and stress indices identified QTL hotspots on chromosomes 2A (54-70 cM) and 2B (75-82 cM). This study enhances our knowledge about the molecular markers associated with grain yield and its components under different stress conditions. It identifies several marker-trait associations for further exploration and validation for marker-assisted breeding. PMID- 29467778 TI - Effects of Inundation, Nutrient Availability and Plant Species Diversity on Fine Root Mass and Morphology Across a Saltmarsh Flooding Gradient. AB - Saltmarsh plants are exposed to multiple stresses including tidal inundation, salinity, wave action and sediment anoxia, which require specific root system adaptations to secure sufficient resource capture and firm anchorage in a temporary toxic environment. It is well known that many saltmarsh species develop large below-ground biomass (roots and rhizomes) but relations between fine roots, in particular, and the abiotic conditions in salt marshes are widely unknown. We studied fine root mass (<2 mm in diameter), fine root depth distribution and fine root morphology in three typical communities (Spartina anglica-dominated pioneer zone, Atriplex portulacoides-dominated lower marsh, Elytrigia atherica-dominated upper marsh) across elevational gradients in two tidal salt marshes of the German North Sea coast [a mostly sandy marsh on a barrier island (Spiekeroog), and a silty-clayey marsh on the mainland coast (Westerhever)]. Fine root mass in the 0 40 cm profile ranged between 750 and 2,500 g m-2 in all plots with maxima at both sites in the lower marsh with intermediate inundation frequency and highest plant species richness indicating an effect of biodiversity on fine root mass. Fine root mass and, even more, total fine root surface area (maximum 340 m2 m-2) were high compared to terrestrial grasslands, and were greater in the nutrient-poorer Spiekeroog marsh. Fine root density showed only a slight or no decrease toward 40 cm depth. We conclude that the standing fine root mass and morphology of these salt marshes is mainly under control of species identity and nutrient availability, but species richness is especially influential. The plants of the pioneer zone and lower marsh possess well adapted fine roots and large standing root masses despite the often water-saturated sediment. PMID- 29467779 TI - OsVIL2 Regulates Spikelet Development by Controlling Regulatory Genes in Oryza sativa. AB - Flower organ patterning is accomplished by spatial and temporal functioning of various regulatory genes. We previously reported that Oryza sativa VIN3-LIKE 2 (OsVIL2) induces flowering by mediating the trimethylation of Histone H3 on LFL1 chromatin. In this study, we report that OsVIL2 also plays crucial roles during spikelet development. Two independent lines of T-DNA insertional mutants in the gene displayed altered organ numbers and abnormal morphology in all spikelet organs. Scanning electron microscopy showed that osvil2 affected organ primordia formation during early spikelet development. Expression analysis revealed that OsVIL2 is expressed in all stages of the spikelet developmental. Transcriptome analysis of developing spikelets revealed that several regulatory genes involved in that process and the formation of floral organs were down-regulated in osvil2. These results suggest that OsVIL2 is required for proper expression of the regulatory genes that control floral organ number and morphology. PMID- 29467780 TI - Development and Applications of a High Throughput Genotyping Tool for Polyploid Crops: Single Nucleotide Polymorphism (SNP) Array. AB - Polypoid species play significant roles in agriculture and food production. Many crop species are polyploid, such as potato, wheat, strawberry, and sugarcane. Genotyping has been a daunting task for genetic studies of polyploid crops, which lags far behind the diploid crop species. Single nucleotide polymorphism (SNP) array is considered to be one of, high-throughput, relatively cost-efficient and automated genotyping approaches. However, there are significant challenges for SNP identification in complex, polyploid genomes, which has seriously slowed SNP discovery and array development in polyploid species. Ploidy is a significant factor impacting SNP qualities and validation rates of SNP markers in SNP arrays, which has been proven to be a very important tool for genetic studies and molecular breeding. In this review, we (1) discussed the pros and cons of SNP array in general for high throughput genotyping, (2) presented the challenges of and solutions to SNP calling in polyploid species, (3) summarized the SNP selection criteria and considerations of SNP array design for polyploid species, (4) illustrated SNP array applications in several different polyploid crop species, then (5) discussed challenges, available software, and their accuracy comparisons for genotype calling based on SNP array data in polyploids, and finally (6) provided a series of SNP array design and genotype calling recommendations. This review presents a complete overview of SNP array development and applications in polypoid crops, which will benefit the research in molecular breeding and genetics of crops with complex genomes.

AB - Phytochelatins (PCs) catalyzed by phytochelatin synthases (PCS) are important for the detoxification of metals in plants and other living organisms. In this study, we isolated a PCS gene (VsPCS1) from Vicia sativa and investigated its role in regulating cadmium (Cd) tolerance. Expression of VsPCS1 was induced in roots of V. sativa under Cd stress. Analysis of subcellular localization showed that VsPCS1 was localized in the cytoplasm of mesophyll protoplasts of V. sativa. Overexpression of VsPCS1 (35S::VsPCS1, in wild-type background) in Arabidopsis thaliana could complement the defects of Cd tolerance of AtPCS1-deficent mutant (atpcs1). Compared with atpcs1 mutants, 35S::VsPCS1/atpcs1 (in AtPCS1-deficent mutant background) transgenic plants significantly lowered Cd-fluorescence intensity in mesophyll cytoplasm, accompanied with enhanced Cd-fluorescence intensity in the vacuoles, demonstrating that the increased Cd tolerance may be attributed to the increased PC-based sequestration of Cd into the vacuole. Furthermore, overexpressing VsPCS1 could enhance the Cd tolerance in 35S::VsPCS1, but have no effect on Cd accumulation and distribution, showing the same level of Cd-fluorescence intensity between 35S::VsPCS1 and wild-type (WT) plants. Further analysis indicated this increased tolerance in 35S::VsPCS1 was possibly due to the increased PCs-chelated Cd in cytosol. Taken together, a functional PCS1 homolog from V. sativa was identified, which hold a strong catalyzed property for the synthesis of high-order PCs that retained Cd in the cytosol rather the vacuole. These findings enrich the original model of Cd detoxification mediated by PCS in higher plants. PMID- 29467782 TI - LasDelta5315 Effector Induces Extreme Starch Accumulation and Chlorosis as Ca. Liberibacter asiaticus Infection in Nicotiana benthamiana. AB - Huanglongbing (HLB), a destructive plant bacterial disease, severely impedes worldwide citrus production. HLB is associated with a phloem-limited alpha proteobacterium, Candidatus Liberibacter asiaticus (Las). Las infection causes yellow shoots and blotchy mottle on leaves and is associated with excessive starch accumulation. However, the mechanisms underlying the starch accumulation remain unknown. We previously showed that the Las5315mp effector induced callose deposition and cell death in Nicotiana benthamiana. In this study, we demonstrated that Las can experimentally infect N. benthamiana via dodder transmission. Furthermore, we revealed another key function of the Las5315 effector by demonstrating that transient expression of the truncated form of the effector, LasDelta5315, induced excessive starch accumulation by 6 fold after 8 dpi in N. benthamiana after removal of the chloroplast transit peptide from the Las5315mp. The induction mechanisms of LasDelta5315 in N. benthamiana were attributed to the up-regulation of ADP-glucose pyrophosphorylase, granule-bound starch synthase, soluble starch synthase, and starch branching enzyme for increasing starch production, and to the significant down-regulation of the starch degradation enzymes: alpha-glucosidase, alpha-amylase, and glycosyl hydrolase for decreasing starch degradation. This is the first report that Las can infect the model plant N. benthamiana. Using this model plant, we demonstrated that the LasDelta5315 effector caused the most prominent HLB symptoms, starch accumulation and chlorosis as Las infection in N. benthamiana. Altogether the Las 5315 effector is critical for Las pathogenesis, and therefore, an important target for interference. PMID- 29467783 TI - A Genomic View of Alternative Splicing of Long Non-coding RNAs during Rice Seed Development Reveals Extensive Splicing and lncRNA Gene Families. AB - Alternative splicing (AS) is a key modulator of development in many eukaryotic organisms. In plants, alternative splice forms of non-coding RNAs (ncRNAs) are known to modulate flowering time in Arabidopsis and fertility in rice. Here we demonstrate that alternative splicing of coding and long non-coding RNAs occurs during rice seed development by comparing AS in immature seeds vs. embryo and endosperm of mature seeds. Based on computational predictions of AS events determined from a Bayesian analysis of junction counts of RNA-seq datasets, differential splicing of protein-coding, and non-coding RNAs was determined. In contrast to roots, leaves, flowers, buds, and reproductive meristems, developing seeds had 5.8-57 times more predicted AS. Primers designed to span introns and exons were used to detect AS events predicted by rMATs in cDNA derived from early (milk) seed, embryo, and endosperm. Comparing milk seed vs. mature embryo and endosperm, AS of MORC7 (a gene implicated in epigenetic gene silencing), was markedly different. Long non-coding RNAs (lncRNAs) also underwent AS during the transition from milk seed to mature embryo and endosperm, with a complex gene structure, and were more extensively processed than predicted by current genome annotation. Exon retention of lncRNAs was enhanced in embryos. Searching all 5,515 lncRNAs in the NCBI genome annotation uncovered gene families based on highly conserved regions shared by groups of 3-35 lncRNAs. The homologies to other lncRNAs, as well as homologies to coding sequences, and the genomic context of lncRNAs provide inroads for functional analysis of multi-exonic lncRNAs that can be extensively processed during seed development. PMID- 29467784 TI - Heterologous Expression of the Cotton NBS-LRR Gene GbaNA1 Enhances Verticillium Wilt Resistance in Arabidopsis. AB - Verticillium wilt caused by Verticillium dahliae results in severe losses in cotton, and is economically the most destructive disease of this crop. Improving genetic resistance is the cleanest and least expensive option to manage Verticillium wilt. Previously, we identified the island cotton NBS-LRR-encoding gene GbaNA1 that confers resistance to the highly virulent V. dahliae isolate Vd991. In this study, we expressed cotton GbaNA1 in the heterologous system of Arabidopsis thaliana and investigated the defense response mediated by GbaNA1 following inoculations with V. dahliae. Heterologous expression of GbaNA1 conferred Verticillium wilt resistance in A. thaliana. Moreover, overexpression of GbaNA1 enabled recovery of the resistance phenotype of A. thaliana mutants that had lost the function of GbaNA1 ortholog gene. Investigations of the defense response in A. thaliana showed that the reactive oxygen species (ROS) production and the expression of genes associated with the ethylene signaling pathway were enhanced significantly following overexpression of GbaNA1. Intriguingly, overexpression of the GbaNA1 ortholog from Gossypium hirsutum (GhNA1) in A. thaliana did not induce the defense response of ROS production due to the premature termination of GhNA1, which lacks the encoded NB-ARC and LRR motifs. GbaNA1 therefore confers Verticillium wilt resistance in A. thaliana by the activation of ROS production and ethylene signaling. These results demonstrate the functional conservation of the NBS-LRR-encoding GbaNA1 in a heterologous system, and the mechanism of this resistance, both of which may prove valuable in incorporating GbaNA1-mediated resistance into other plant species. PMID- 29467785 TI - Morphological and Molecular Data Reveal Three Distinct Populations of Indian Wild Rice Oryza rufipogon Griff. Species Complex. AB - Wild relatives of crops possess adaptive mutations for agronomically important traits, which could play significant role in crop improvement for sustainable agriculture. However, global climate change and human activities pose serious threats to the natural habitats leading to erosion of genetic diversity of wild rice populations. The purpose of this study was to explore and characterize India's huge untapped wild rice diversity in Oryza rufipogon Griff. species complex from a wide range of ecological niches. We made strategic expeditions around diversity hot spots in 64 districts of nine different agro-climatic zones of the country and collected 418 wild rice accessions. Significant variation was observed among the accessions for 46 morphological descriptors, allowing classification into O. nivara, O. rufipogon, and O. sativa f. spontanea morpho taxonomic groups. Genome-specific pSINE1 markers confirmed all the accessions having AA genome, which were further classified using ecotype-specific pSINE1 markers into annual, perennial, intermediate, and an unknown type. Principal component analysis revealed continuous variation for the morphological traits in each ecotype group. Genetic diversity analysis based on multi-allelic SSR markers clustered these accessions into three major groups and analysis of molecular variance for nine agro-climatic zones showed that 68% of the genetic variation was inherent amongst individuals while only 11% of the variation separated the zones, though there was significant correlation between genetic and spatial distances of the accessions. Model based population structure analysis using genome wide bi-allelic SNP markers revealed three sub-populations designated 'Pro Indica,' 'Pro-Aus,' and 'Mid-Gangetic,' which showed poor correspondence with the morpho-taxonomic classification or pSINE1 ecotypes. There was Pan-India distribution of the 'Pro-Indica' and 'Pro-Aus' sub-populations across agro climatic zones, indicating a more fundamental grouping based on the ancestry closely related to 'Indica' and 'Aus' groups of rice cultivars. The Pro-Indica population has substantial presence in the Eastern Himalayan Region and Lower Gangetic Plains, whereas 'Pro-Aus' sub-population was predominant in the Upper Gangetic Plains, Western Himalayan Region, Gujarat Plains and Hills, and Western Coastal Plains. In contrast 'Mid-Gangetic' population was largely concentrated in the Mid Gangetic Plains. The information presented here will be useful in the utilization of wild rice resources for varietal improvement. PMID- 29467787 TI - The Effect of Grain Position on Genetic Improvement of Grain Number and Thousand Grain Weight in Winter Wheat in North China. AB - Genetic improvements have significantly contributed to wheat production. Five wheat cultivars-widely grown in north China in the 1950s, 1990s, or 2010s-were grown in field experiments conducted in the 2014-2015 and 2015-2016 growing seasons. This study evaluated the genetic progress in wheat grain yield and its related traits in north China and explored how breeding and selection have influenced grain numbers and weights within spikelets in the past 60 years. The results showed that the significant increases in grain yield in the past 60 years were mainly due to increases in grain number per spike and grain weight, while spike number per m2 has not changed significantly. Improvements in thousand grain weight (TGW) from the 1950s to 2010s have occurred at four grain positions (G1 to G4). The relative contribution of G4 to TGW increased over time, but was much less than the contributions of G1, G2, and G3. Indeed, the average grain weight at G4 was much less than that of 1000 grains. The increase in grain number per spike since the 1950s was mainly due to an increase in grain number at G1, G2 and G3, with the relative contribution of grain position to grain number being G1 > G2 > G3 > G4. Dwarfing genes increased grain number per spike and grain number at G3 and G4, but not TGW. In future, yields could be boosted by enhancing grain weight at G4 and grain number at G3 and G4, while maintaining those at G1 and G2. PMID- 29467786 TI - Auxin and Gibberellins Are Required for the Receptor-Like Kinase ERECTA Regulated Hypocotyl Elongation in Shade Avoidance in Arabidopsis. AB - Plants use shade avoidance strategy to escape the canopy shade when grown under natural conditions. Previous studies showed that the Arabidopsis receptor-like kinase ERECTA (ER) is involved in shade avoidance syndrome. However, the mechanisms of ER in modulating SAR by promoting hypocotyl elongation are unknown yet. Here, we report that ER regulated hypocotyl elongation in shade avoidance requires auxin and gibberellins (GAs). The T-DNA insertional ER mutant er-3 shows a less hypocotyl length than that in Col-0 wild type. Promoter::GUS staining analysis shows that ER and its paralogous genes ERECTA-LIKE1 (ERL1) and ERECTA LIKE2 (ERL2) are differentially expressed in the seedlings, of which only ER is most obviously upregulated in the hypocotyl by shade treatment. Exogenous feeding assay by using media-application with vertical-grown of Arabidopsis seedlings showed that the hypocotyl length of er-3 is partially promoted by indol-3-acetic acid (IAA), while it is relatively insensitive of er-3 to various concentrations of IAA than that of Col-0. Hypocotyl elongation of er-3 is promoted similar to that of Col-0 by high temperature in the white light condition, but the elongation was not significantly affected by the treatment of the auxin transport inhibitor 1-N-naphthylphthalamic acid (NPA). Exogenous GA3 increased the hypocotyl elongation of both er-3 and the wild type in the shade condition, and the GA3 biosynthesis inhibitor paclobutrazol (PAC) severely inhibits the hypocotyl elongation of Col-0 and er-3. Further analysis showed that auxin biosynthesis inhibitors yucasin and L-kynurenine remarkably inhibited the hypocotyl elongation of er-3 while yucasin shows a more severe inhibition to er-3 than Col-0. Relative expression of genes regulating auxin homeostasis and signaling, and GA homeostasis is less in er-3 than that in Col-0. Furthermore, genetic evidences show that ER regulated hypocotyl elongation is dependent of PHYTOCHROME B (PHYB). Overall, we propose that ER regulated shade avoidance by promoting hypocotyl elongation is PHYB-dependent and requires auxin and GAs. PMID- 29467788 TI - Toxicological and Biochemical Analyses Demonstrate the Absence of Lethal or Sublethal Effects of cry1C- or cry2A-Expressing Bt Rice on the Collembolan Folsomia candida. AB - Assessing the potential effects of insect-resistant genetically engineered (GE) plants on collembolans is important because these common soil arthropods may be exposed to insecticidal proteins produced in GE plants by ingestion of plant residues, crop pollen, or root exudates. Laboratory studies were conducted to evaluate the potential effects of two Bacillus thuringiensis (Bt)-rice lines expressing Cry1C and Cry2A in pollen and leaves and of their non-Bt conventional isolines on the fitness of the collembolan Folsomia candida and on the activities of its antioxidant-related enzymes, superoxide dismutase and peroxidase, and of its detoxification-related enzymes, glutathione reductase and glutathione S transferase. Survival, development, reproduction, and the intrinsic rate of increase (rm) were not significantly reduced when F. candida fed on the Bt rice pollen or leaf powder than on the non-Bt rice materials; these parameters, however, were significantly reduced when F. candida fed on non-Bt rice pollen or non-Bt leaf-based diets containing the protease inhibitor E-64 at 75 MUg/g. The activities of the antioxidant-related and detoxification-related enzymes in F. candida were not significantly affected when F. candida fed on the Bt rice materials, but were significantly increased when F. candida fed on the non-Bt rice materials containing E-64. The results demonstrate that Cry1C and Cry2A are not toxic to F. candida, and also indicate the absence of unintended effects on the collembolan caused by any change in plant tissue nutritional composition due to foreign gene transformation. PMID- 29467789 TI - Tracking Nitrogen Source Using delta15N Reveals Human and Agricultural Drivers of Seagrass Degradation across the British Isles. AB - Excess nutrients shift the ecological balance of coastal ecosystems, and this eutrophication is an increasing problem across the globe. Nutrient levels may be routinely measured, but monitoring rarely attempts to determine the source of these nutrients, even though bio-indicators are available. Nitrogen stable isotope analysis in biota is one such bio-indicator, but across the British Isles, this is rarely used. In this study, we provide the first quantitative evidence of the anthropogenic drivers of reduced water quality surrounding seagrass meadows throughout the British Isles using the stable nitrogen isotope delta15N. The values of delta15N ranged from 3.15 to 20.160/00 (Mean +/- SD = 8.69 +/- 3.500/00), and were high within the Thames Basin suggesting a significant influx of urban sewage and livestock effluent into the system. Our study provides a rapid 'snapshot' indicating that many seagrass meadows in the British Isles are under anthropogenic stress given the widespread inefficiencies of current sewage treatment and farming practices. Ten of the 11 seagrass meadows sampled are within European marine protected sites. The 10 sites all contained seagrass contaminated by nutrients of a human and livestock waste origin leading us to question whether generic blanket protection is working for seagrasses in the United Kingdom. Infrastructure changes will be required if we are to develop strategic wastewater management plans that are effective in the long-term at protecting our designated Special Areas of Conservation. Currently, sewage pollution is a concealed issue; little information exists and is not readily accessible to members of the public. PMID- 29467790 TI - Classification of Autism Spectrum Disorder Using Random Support Vector Machine Cluster. AB - Autism spectrum disorder (ASD) is mainly reflected in the communication and language barriers, difficulties in social communication, and it is a kind of neurological developmental disorder. Most researches have used the machine learning method to classify patients and normal controls, among which support vector machines (SVM) are widely employed. But the classification accuracy of SVM is usually low, due to the usage of a single SVM as classifier. Thus, we used multiple SVMs to classify ASD patients and typical controls (TC). Resting-state functional magnetic resonance imaging (fMRI) data of 46 TC and 61 ASD patients were obtained from the Autism Brain Imaging Data Exchange (ABIDE) database. Only 84 of 107 subjects are utilized in experiments because the translation or rotation of 7 TC and 16 ASD patients has surpassed +/-2 mm or +/-2 degrees . Then the random SVM cluster was proposed to distinguish TC and ASD. The results show that this method has an excellent classification performance based on all the features. Furthermore, the accuracy based on the optimal feature set could reach to 96.15%. Abnormal brain regions could also be found, such as inferior frontal gyrus (IFG) (orbital and opercula part), hippocampus, and precuneus. It is indicated that the method of random SVM cluster may apply to the auxiliary diagnosis of ASD. PMID- 29467792 TI - Evaluation of Bioinformatics Approaches for Next-Generation Sequencing Analysis of microRNAs with a Toxicogenomics Study Design. AB - MicroRNAs (miRNAs) are key post-transcriptional regulators that affect protein translation by targeting mRNAs. Their role in disease etiology and toxicity are well recognized. Given the rapid advancement of next-generation sequencing techniques, miRNA profiling has been increasingly conducted with RNA-seq, namely miRNA-seq. Analysis of miRNA-seq data requires several steps: (1) mapping the reads to miRBase, (2) considering mismatches during the hairpin alignment (windowing), and (3) counting the reads (quantification). The choice made in each step with respect to the parameter settings could affect miRNA quantification, differentially expressed miRNAs (DEMs) detection and novel miRNA identification. Furthermore, these parameters do not act in isolation and their joint effects impact miRNA-seq results and interpretation. In toxicogenomics, the variation associated with parameter setting should not overpower the treatment effect (such as the dose/time-dependent effect). In this study, four commonly used miRNA-seq analysis tools (i.e., miRDeep2, miRExpress, miRNAkey, sRNAbench) were comparatively evaluated with a standard toxicogenomics study design. We tested 30 different parameter settings on miRNA-seq data generated from thioacetamide treated rat liver samples for three dose levels across four time points, followed by four normalization options. Because both miRExpress and miRNAkey yielded larger variation than that of the treatment effects across multiple parameter settings, our analyses mainly focused on the side-by-side comparison between miRDeep2 and sRNAbench. While the number of miRNAs detected by miRDeep2 was almost the subset of those detected by sRNAbench, the number of DEMs identified by both tools was comparable under the same parameter settings and normalization method. Change in the number of nucleotides out of the mature sequence in the hairpin alignment (window option) yielded the largest variation for miRNA quantification and DEMs detection. However, such a variation is relatively small compared to the treatment effect when the study focused on DEMs that are more critical to interpret the toxicological effect. While the normalization methods introduced a large variation in DEMs, toxic behavior of thioacetamide showed consistency in the trend of time-dose responses. Overall, miRDeep2 was found to be preferable over other choices when the window option allowed up to three nucleotides from both ends. PMID- 29467791 TI - Next Generation Sequencing Methods for Diagnosis of Epilepsy Syndromes. AB - Epilepsy is a neurological disorder characterized by an increased predisposition for seizures. Although this definition suggests that it is a single disorder, epilepsy encompasses a group of disorders with diverse aetiologies and outcomes. A genetic basis for epilepsy syndromes has been postulated for several decades, with several mutations in specific genes identified that have increased our understanding of the genetic influence on epilepsies. With 70-80% of epilepsy cases identified to have a genetic cause, there are now hundreds of genes identified to be associated with epilepsy syndromes which can be analyzed using next generation sequencing (NGS) techniques such as targeted gene panels, whole exome sequencing (WES) and whole genome sequencing (WGS). For effective use of these methodologies, diagnostic laboratories and clinicians require information on the relevant workflows including analysis and sequencing depth to understand the specific clinical application and diagnostic capabilities of these gene sequencing techniques. As epilepsy is a complex disorder, the differences associated with each technique influence the ability to form a diagnosis along with an accurate detection of the genetic etiology of the disorder. In addition, for diagnostic testing, an important parameter is the cost-effectiveness and the specific diagnostic outcome of each technique. Here, we review these commonly used NGS techniques to determine their suitability for application to epilepsy genetic diagnostic testing. PMID- 29467793 TI - Decomposing Additive Genetic Variance Revealed Novel Insights into Trait Evolution in Synthetic Hexaploid Wheat. AB - Whole genome duplication (WGD) is an evolutionary phenomenon, which causes significant changes to genomic structure and trait architecture. In recent years, a number of studies decomposed the additive genetic variance explained by different sets of variants. However, they investigated diploid populations only and none of the studies examined any polyploid organism. In this research, we extended the application of this approach to polyploids, to differentiate the additive variance explained by the three subgenomes and seven sets of homoeologous chromosomes in synthetic allohexaploid wheat (SHW) to gain a better understanding of trait evolution after WGD. Our SHW population was generated by crossing improved durum parents (Triticum turgidum; 2n = 4x = 28, AABB subgenomes) with the progenitor species Aegilops tauschii (syn Ae. squarrosa, T. tauschii; 2n = 2x = 14, DD subgenome). The population was phenotyped for 10 fungal/nematode resistance traits as well as two abiotic stresses. We showed that the wild D subgenome dominated the additive effect and this dominance affected the A more than the B subgenome. We provide evidence that this dominance was not inflated by population structure, relatedness among individuals or by longer linkage disequilibrium blocks observed in the D subgenome within the population used for this study. The cumulative size of the three homoeologs of the seven chromosomal groups showed a weak but significant positive correlation with their cumulative explained additive variance. Furthermore, an average of 69% for each chromosomal group's cumulative additive variance came from one homoeolog that had the highest explained variance within the group across all 12 traits. We hypothesize that structural and functional changes during diploidization may explain chromosomal group relations as allopolyploids keep balanced dosage for many genes. Our results contribute to a better understanding of trait evolution mechanisms in polyploidy, which will facilitate the effective utilization of wheat wild relatives in breeding. PMID- 29467794 TI - Detection of Potential Problematic Cytb Gene Sequences of Fishes in GenBank. AB - Fishes are, by far, the most diverse group of vertebrates. Their classification relies heavily on morphology. In practice, the correct morphological identification of species often depends on personal experience because many species vary in their body shape, color and other external characters. Thus, the identification of a species may be prone to errors. Due to the rapid development of molecular biology, the number of sequences of fishes deposited in GenBank has grown explosively. These published data likely contain errors owing to invalid or incorrectly identified species. The erroneous data can lead to downstream problems. Thus, it is critical that such errors get identified and corrected. A strategy based on DNA barcoding can detect potentially erroneous data, especially when intraspecific K2P variation exceeds interspecific K2P divergence. Analyses of the most used DNA marker for fishes (mitochondrial Cytb) discovers that intraspecific differences of fishes are generally less than 1%, while interspecific differences are generally higher than 10%. Based on this ruler, our analyses identify 1,303 potential problematic Cytb sequences of fishes in GenBank and point to taxonomic problems, errors in identification, genetic introgression and other concerns. Care must be taken to avoid the perpetuation of errors when using these available data. PMID- 29467795 TI - Genome-Wide Study of YABBY Genes in Upland Cotton and Their Expression Patterns under Different Stresses. AB - Members of the YABBY gene family, a small plant-specific family of genes, have been proposed to function in specifying abaxial cell fate. Although to date little has been learned about cotton YABBY genes, completion of the cotton genome enables a comprehensive genome-wide analysis of YABBY genes in cotton. Here, a total of 12, 12, and 23 YABBY genes were identified in Gossypium arboreum (2n = 26, A2), G. raimondii (2n = 26, D5), and G. hirsutum (2n = 4x = 52, [AD]t), respectively. Sequence analysis showed that the N-terminal zinc-finger and C terminal YABBY domains in YABBY proteins are highly conserved among cotton, Arabidopsis, and rice. Eighty-five genes from eight sequenced species naturally clustered into five groups, and the YAB2-like group could be divided into three sub-groups, indicating that YABBYs are highly conserved among the examined species. Orthologs from the At and Dt sub-genomes (where "t" indicates tetraploid) showed good collinearity, indicating that YABBY loci are highly conserved between these two sub-genomes. Whole-genome duplication was the primary cause of upland cotton YABBY gene expansion, segmental duplication played important roles in YABBY gene expansion within the At and Dt sub-genomes, and the YAB5-like group was mainly generated by segmental duplication. The long-terminal repeat retroelements Copia and Gypsy were identified as major transposable elements accompanying the appearance of duplicated YABBY genes, suggesting that transposable element expansion might be involved in gene duplication. Selection pressure analyses using PAML revealed that relaxed purifying selection might be the main impetus during evolution of YABBY genes in the examined species. Furthermore, exon/intron pattern and motif analyses indicated that genes within the same group were significantly conserved between Arabidopsis and cotton. In addition, the expression patterns in different tissues suggest that YABBY proteins may play roles in ovule development because YABBYs are highly expressed in ovules. The expression pattern of YABBY genes showed that approximately half of the YABBYs were down-regulated under different stress treatments. Collectively, our results represent a comprehensive genome-wide study of the YABBY gene family, which should be helpful in further detailed studies on the gene function and evolution of YABBY genes in cotton. PMID- 29467796 TI - Biochemical characterization of a phospholipase A2 homologue from the venom of the social wasp Polybia occidentalis. AB - Background: Wasp venoms constitute a molecular reservoir of new pharmacological substances such as peptides and proteins, biological property holders, many of which are yet to be identified. Exploring these sources may lead to the discovery of molecules hitherto unknown. This study describes, for the first time in hymenopteran venoms, the identification of an enzymatically inactive phospholipase A2 (PLA2) from the venom of the social wasp Polybia occidentalis. Methods: P. occidentalis venom was fractioned by molecular exclusion and reverse phase chromatography. For the biochemical characterization of the protein, 1D and 2D SDS-PAGE were performed, along with phospholipase activity assays on synthetic substrates, MALDI-TOF mass spectrometry and sequencing by Edman degradation. Results: The protein, called PocTX, was isolated using two chromatographic steps. Based on the phospholipase activity assay, electrophoresis and mass spectrometry, the protein presented a high degree of purity, with a mass of 13,896.47 Da and a basic pI. After sequencing by the Edman degradation method, it was found that the protein showed a high identity with snake venom PLA2 homologues. Conclusion: This is the first report of an enzymatically inactive PLA2 isolated from wasp venom, similar to snake PLA2 homologues. PMID- 29467797 TI - Peptidomic investigation of Neoponera villosa venom by high-resolution mass spectrometry: seasonal and nesting habitat variations. AB - Background: Advancements in proteomics, including the technological improvement in instrumentation, have turned mass spectrometry into an indispensable tool in the study of venoms and toxins. In addition, the advance of nanoscale liquid chromatography coupled to nanoelectrospray mass spectrometry allows, due to its high sensitivity, the study of venoms from species previously left aside, such as ants. Ant venoms are a complex mixture of compounds used for defense, predation or communication purposes. The venom from Neoponera ants, a genus restricted to Neotropical regions, is known to have cytolytic, hemolytic, antimicrobial and insecticidal activities. Moreover, venoms from several Neoponera species have been compared and differences in their toxicity related to nesting habitat variation were reported. Therefore, the present study aimed to perform a deep peptidomic analysis of Neoponera villosa venom and a comparison of seasonal and nesting habitat variations using high-resolution mass spectrometry. Methods: Specimens of N. villosa ants were captured in Panga Natural Reserve (Uberlandia, MG, Brazil) from arboreal and ground-dwelling nests during summer and winter time. The venom glands were dissected, pooled and disrupted by ultra-sonic waves. The venom collected from different habitats (arboreal and ground-dwelling) and different seasons (summer and winter) was injected into a nanoACQUITY ULPC hyphened to a Q-Exactive Orbitrap mass spectrometer. The raw data were analyzed using PEAKS 7. Results: The results showed a molecular diversity of more than 500 peptides among these venoms, mostly in the mass range of 800-4000 Da. Mutations and post-translational modifications were described and differences among the venoms were observed. Part of the peptides matched with ponericins, a well-known antimicrobial peptide family. In addition, smaller fragments related to ponericins were also identified, suggesting that this class of antimicrobial peptide might undergo enzymatic cleavages. Conclusion: There are substantial differences among the venom of N. villosa ants collected in different seasons and from different nest habitats. The venom composition is affected by climate changes that influence prey availability and predator presence. Clearly, nano-LC MS boosted the knowledge about ant venom, a rich source of unexplored and promising bioactive compounds. PMID- 29467798 TI - Female nursing partner choice in a population of wild house mice (Mus musculus domesticus). AB - Abstract: Background: Communal nursing in house mice is an example of cooperation where females pool litters in the same nest and indiscriminately nurse own and other offspring despite potential exploitation. The direct fitness benefits associated with communal nursing shown in laboratory studies suggest it to be a selected component of female house mice reproductive behaviour. However, past studies on communal nursing in free-living populations have debated whether it is a consequence of sharing the same nest or an active choice. Here using data from a long-term study of free-living, wild house mice we investigated individual nursing decisions and determined what factors influenced a female's decision to nurse communally. Results: Females chose to nurse solitarily more often than expected by chance, but the likelihood of nursing solitarily decreased when females had more partners available. While finding no influence of pairwise relatedness on partner choice, we observed that females shared their social environment with genetically similar individuals, suggesting a female's home area consisted of related females, possibly facilitating the evolution of cooperation. Within such a home area females were more likely to nest communally when the general relatedness of her available options was relatively high. Females formed communal nests with females that were familiar through previous associations and had young pups of usually less than 5 days old. Conclusions: Our findings suggest that communal nursing was not a by-product of sharing the same nesting sites, but females choose communal nursing partners from a group of genetically similar females, and ultimately the decision may then depend on the pool of options available. Social partner choice proved to be an integrated part of cooperation among females, and might allow females to reduce the conflict over number of offspring in a communal nest and milk investment towards own and other offspring. We suggest that social partner choice may be a general mechanism to stabilize costly cooperation.

AB - Background: While the adverse metabolic effects of exposure to obesogenic diets during both the prenatal and early postnatal period are well established, the relative impact of exposure during these separate developmental windows remains unclear. This study aimed to assess the relative contribution of exposure to a maternal cafeteria diet during pregnancy and lactation on body weight, fat mass and expression of lipogenic and adipokine genes in the offspring. Methods: Wistar rats were fed either a control chow (Control, n = 14) or obesogenic cafeteria diet (CAF, n = 12) during pregnancy and lactation. Pups were cross-fostered to another dam in either the same or different dietary group within 24 h of birth. Body weight, body fat mass and expression of lipogenic and adipokine genes in subcutaneous and visceral adipose tissues were determined in offspring at weaning and 3 weeks post-weaning. Results: Offspring suckled by CAF dams had a lower body weight (P < 0.05), but ~ 2-fold higher percentage body fat at weaning than offspring suckled by Control dams (P < 0.01), independent of whether they were born to a Control or CAF dam. At 6 weeks of age, after all offspring were weaned onto standard chow, males and females suckled by CAF dams remained lighter (P < 0.05) than offspring suckled by Control dams, but the percentage fat mass was no longer different between groups. Sterol Regulatory Element Binding Protein-1c (SREBP-1c) mRNA expression was ~ 25% lower in offspring suckled by cafeteria dams in males at weaning (P < 0.05) and in females at 6 weeks of age (P < 0.05). Exposure to a cafeteria diet during the suckling period alone also resulted in increased adipocyte Peroxisome Proliferator Activated Receptor-gamma (PPAR-gamma) mRNA expression in females, and adiponectin and leptin mRNA expression in both sexes at weaning. Conclusions: The findings from this study point to the critical role of the suckling period for deposition of adipose tissue in rodents, and the potential role of altered adipocyte gene expression in mediating these effects.

AB - Amiodarone-associated optic neuropathy (AAON) is a controversial diagnosis with possible impact on vital cardiac therapy decisions. This retrospective case series aims for application of distinguishing features of AAON versus non arteritic ischaemic optic neuropathy (NAION): Bilaterality, mode of onset, degree of optic nerve dysfunction, structure of uninvolved disc (unilateral cases), and systemic toxic effects. Applying these criteria to patients with disc swelling under amiodarone, the authors identified four unilateral disc swellings, one with NAION-typical features only and three with one or more NAION-atypical features. All three sequential and six bilateral cases showed one or more NAION-atypical features. The 12 cases highlight the persisting diagnostic dilemma arising from diversity of presentation, lack of plausible pathomechanism, and controversial existence of the entity itself. PMID- 29467800 TI - Resting metabolic rate of obese patients under very low calorie ketogenic diet. AB - Background: The resting metabolic rate (RMR) decrease, observed after an obesity reduction therapy is a determinant of a short-time weight regain. Thus, the objective of this study was to evaluate changes in RMR, and the associated hormonal alterations in obese patients with a very low-calorie ketogenic (VLCK) diet induced severe body weight (BW) loss. Method: From 20 obese patients who lost 20.2 kg of BW after a 4-months VLCK-diet, blood samples and body composition analysis, determined by DXA and MF-Bioimpedance, and RMR by indirect calorimetry, were obtained on four subsequent visits: visit C-1, basal, initial fat mass (FM) and free fat mass (FFM); visit C-2, - 7.2 kg in FM, - 4.3 kg in FFM, maximal ketosis; visit C-3, - 14.4 kg FM, - 4.5 kg FFM, low ketosis; visit C-4, - 16.5 kg FM, - 3.8 kg FFM, no ketosis. Each subject acted as his own control. Results: Despite the large BW reduction, measured RMR varied from basal visit C-1 to visit C-2, - 1.0%; visit C-3, - 2.4% and visit C-4, - 8.0%, without statistical significance. No metabolic adaptation was observed. The absent reduction in RMR was not due to increased sympathetic tone, as thyroid hormones, catecholamines, and leptin were reduced at any visit from baseline. Under regression analysis FFM, adjusted by levels of ketonic bodies, was the only predictor of the RMR changes (R2 = 0.36; p < 0.001). Conclusion: The rapid and sustained weight and FM loss induced by VLCK-diet in obese subjects did not induce the expected reduction in RMR, probably due to the preservation of lean mass. Trial registration: This is a follow up study on a published clinical trial. PMID- 29467803 TI - Vogt-Koyanagi-Harada Disease Presenting as Unilateral Neuroretinits. AB - A 42-year-old female presented with unilateral visual loss associated with systemic symptoms of fever and headache. Although initial ophthalmic examination revealed a unilateral neuroretinitis, investigation for infectious and non infectious causes of neuroretinitis were negative. At our examination, retinal imaging (suggestive of bilateral involvement) along with the results of lumbar puncture (pleocytosis) and clinical findings was consistent with a diagnosis of Vogt-Koyanagi-Harada disease. The patient was treated with intravenous steroids with prompt resolution of her symptoms. Vogt-Koyanagi-Harada disease may present atypically and should be considered in the differential diagnosis of neuroretinitis. PMID- 29467804 TI - Clinical Evaluation and Treatment Outcome of Traumatic Optic Neuropathy in Nepal: A Retrospective Case Series. AB - This study aims to report the clinical features and role of different treatment modalities in final visual outcome in traumatic optic neuropathy (TON). The authors retrospectively reviewed the records of patients with TON over 4 years. There were 37 patients of unilateral TON. Mean age was 28.70 +/- 15.20 years (range: 8-90) and 89% (n = 33) were males. Road traffic accident was the common cause (43.2%), followed by fall injury (35.1%). There was improvement of visual acuity in 51.4% (n = 19) cases. Out of different treatment modalities, high-dose intravenous methylprednisolone (1 g/day) led to significant improvement in final visual acuity (p = 0.013). There was no significant improvement in final visual outcome in patients with poor initial visual acuity and those with intracranial injuries.

AB - The authors present findings in a 39-year-old man with polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes (POEMS) syndrome with bilateral optic disc oedema. He was successfully treated with bortezomib and dexamethasone followed by autologous peripheral blood stem cell transplantation. The peripapillary retinal thickness was reduced in the optical coherence tomographic (OCT) images along with a decrease of the serum vascular endothelial growth factor (VEGF) levels. The authors recommend OCT to monitor the changes in the signs of POEMS syndrome after treatments. PMID- 29467806 TI - Isolated Abducens Palsy Heralding Occult Human Immunodeficiency Virus-Related Lymphoma. AB - A 40-year-old African American man with recently diagnosed Human Immunodeficiency Virus (HIV) presented with isolated left abducens palsy. Initial neuro-imaging and laboratory evaluation, including cerebrospinal fluid (CSF) analysis, were unremarkable. Continued search for causative aetiology revealed systemic lymphoma diagnosed ultimately by bone marrow biopsy. Systemic lymphoma is commonly encountered in the HIV patient population, but presentation can be unusual and has been seen, albeit rarely, in the setting of isolated cranial neuropathy. This case demonstrates the often diligent investigation required in the setting of isolated cranial neuropathies in patients with HIV. PMID- 29467807 TI - Temporary Visual Loss Due to Posterior Reversible Encephalopathy Syndrome in the Case of an End-Stage Renal Disease Patient. AB - Posterior reversible encephalopathy syndrome is a clinical phenomenon associated with headache, altered mental status, seizures, and visual disturbances along with radiographic acute cerebral oedema. Several conditions are correlated with posterior reversible encephalopathy syndrome, with acute hypertension, eclampsia, and cytotoxic agents being the most common. This report presents a case of posterior reversible encephalopathy syndrome in a 45-year-old male with multiple underlying conditions, including hypertension, diabetes, and end-stage renal disease. Sudden onset of bilateral visual loss with mild systemic feature of dizziness was noted on presentation. Radiologic findings showed characteristic findings of posterior reversible encephalopathy syndrome. Following prompt control of hypertension and haemodialysis, resolution of symptoms was noted. PMID- 29467808 TI - Sibling Ethambutol Optic Chiasmopathy. AB - Ethambutol is utilised in the treatment of Mycobacterium avium and Mycobacterium tuberculosis infection. The authors report two siblings who developed the adverse effect of ethambutol-induced optic chiasmopathy, with recovery following cessation of ethambutol. Discussion explores potential genetic predisposition to development of this condition and its resolution. Ethambutol optic neuropathy (EON), Leber's hereditary optic neuropathy (LHON), and other optic neuropathies of mitochondrial origin share a common pathophysiology. Consequently, the authors postulate treatments utilised in LHON, including vitamin B supplementation and idebenone, may have benefit in EON. This article presents concepts for further research, suggesting a potential genetic susceptibility to EON and its treatment. PMID- 29467809 TI - Intermittent Ocular Microflutter in a Patient with Acute-Onset Oscillopsia. AB - Saccadic intrusions are small involuntary saccadic movements that disrupt visual fixation. Among saccadic intrusions without intersaccadic intervals, ocular flutter and opsoclonus are prominent. The saccade amplitude can occasionally be very small, which is referred to as ocular microflutter. The authors present a patient with acute-onset oscillopsia following a non-specific viral condition. An ocular microflutter was subsequently detected using video-oculography. After extensive investigation, a diagnosis of isolated idiopathic or post-viral ocular microflutter was made. The evolution of the condition was favourable, and the progressive improvement of oscillopsia occurred during the following months; however, complete resolution was not achieved. Ocular microflutter is a saccadic intrusion that is rarely described in the literature and is likely go clinically unnoticed because of its small amplitude and the rare use of video-oculography in daily practice. In patients in whom this condition is suspected, the use of video oculography is essential for a correct diagnosis. PMID- 29467810 TI - Brown Syndrome Following Upper Eyelid Ptosis Repair. AB - Brown syndrome is characterised by impaired supraduction worse in adduction due to a restricted superior oblique tendon passing through the trochlea. A few reports have previously described Brown syndrome after upper eyelid surgery, including blepharoplasty and ptosis repair. The authors describe two additional cases of Brown syndrome following ptosis repair. The first case is a 65-year-old woman with new-onset vertical binocular diplopia following bilateral levator advancement surgery. Ocular motility examination demonstrated moderate impairment of elevation in adduction. The second case is a 35-year-old woman who presented with new-onset intermittent binocular diplopia following right upper lid ptosis repair. Examination revealed large vertical fusional amplitudes and a large left intermittent hyperphoria in an alignment pattern consistent with Brown syndrome. Despite presenting after surgery, these cases differ in mechanism. The first case likely occurred due to intraoperative impairment of the superior oblique tendon sheath or trochlea, whereas the second case represented an unmasking of a long standing, previous vertical strabismus that was consistent with a Brown syndrome pattern.

PMID- 29467812 TI - Prelacteal feeding and associated factors among newborns in rural Sidama, south Ethiopia: a community based cross-sectional survey. AB - Background: The practice of giving prelacteal feeds deprive a newborn of valuable nutrients and expose the newborn to risks of infection. Despite its negative health outcomes, prelacteal feeding prevails in Ethiopia. Therefore, the current study was undertaken to assess the prevalence of prelacteal feeding practices and its associated factors in a rural community in south Ethiopia. Methods: We conducted a community based cross-sectional study of 597 mothers of children aged less than six months. Mothers were selected using a multistage cluster sampling technique from Hawela Tula, a rural catchment under Hawassa City Administration. Newborns exposed to any foods, substances or drinks other than human milk before the initiation of breastfeeding or during the first three days of birth were regarded as receiving prelacteal feeds. Descriptive summaries were done to present the main findings; bivariate and multivariate logistic regression analyses were undertaken to identify variables associated with prelacteal feeding practices. Results: Among the total infants, 25.5% (95% confidence interval [CI] 23.5%, 27.5%) were found to be exposed to prelacteal feeds. Boiled water (36.8%) and fresh butter (32.2%) were the top two prelacteal foods. The prevalence of prelacteal feeding was higher among infants whose mothers are housewives, and among infants born to mothers aged between 21 and 34 years. Almost two-third (64.3%) of mothers who exposed their newborn to prelacteal feeds did so with advice from their parents. Mothers who had poor knowledge on breastfeeding were nine times more likely to practice prelacteal feeding compared to those with good knowledge (adjusted odds ratio [AOR] 8.9, 95% CI 4.2, 18.7). Lack of knowledge on the risks associated with prelacteal feeding (AOR 6.8; 95% CI 2.6, 17.8) and misconceptions about breastfeeding (AOR 8.1; 95% CI 3.9, 16.6) were associated with prelacteal feeding. However, mothers' place of delivery and attendance at breastfeeding counseling sessions showed no association with the practice of prelacteal feeding. Conclusions: Prelacteal feeding is commonly practiced in the study area. Raising women's awareness on the consequences of prelacteal feeding is warranted. Involving parents of women when promoting optimal infant feeding practices should be emphasized. PMID- 29467814 TI - Fast phylogenetic inference from typing data. AB - Background: Microbial typing methods are commonly used to study the relatedness of bacterial strains. Sequence-based typing methods are a gold standard for epidemiological surveillance due to the inherent portability of sequence and allelic profile data, fast analysis times and their capacity to create common nomenclatures for strains or clones. This led to development of several novel methods and several databases being made available for many microbial species. With the mainstream use of High Throughput Sequencing, the amount of data being accumulated in these databases is huge, storing thousands of different profiles. On the other hand, computing genetic evolutionary distances among a set of typing profiles or taxa dominates the running time of many phylogenetic inference methods. It is important also to note that most of genetic evolution distance definitions rely, even if indirectly, on computing the pairwise Hamming distance among sequences or profiles. Results: We propose here an average-case linear-time algorithm to compute pairwise Hamming distances among a set of taxa under a given Hamming distance threshold. This article includes both a theoretical analysis and extensive experimental results concerning the proposed algorithm. We further show how this algorithm can be successfully integrated into a well known phylogenetic inference method, and how it can be used to speedup querying local phylogenetic patterns over large typing databases. PMID- 29467813 TI - Subunits of human condensins are potential therapeutic targets for cancers. AB - The main role of condensins is to regulate chromosome condensation and segregation during cell cycles. Recently, it has been suggested in the literatures that subunits of condensin I and condensin II are involved in some human cancers. This paper will first briefly discuss discoveries of human condensins, their components and structures, and their multiple cellular functions. This will be followed by reviews of most recent studies on subunits of human condensins and their dysregulations or mutations in human cancers. It can be concluded that many of these subunits have potentials to be novel targets for cancer therapies. However, hCAP-D2, a subunit of human condensin I, has not been directly documented to be associated with any human cancers to date. This review hypothesizes that hCAP-D2 can also be a potential therapeutic target for human cancers, and therefore that all subunits of human condensins are potential therapeutic targets for human cancers. PMID- 29467815 TI - Derivative-free neural network for optimizing the scoring functions associated with dynamic programming of pairwise-profile alignment. AB - Background: A profile-comparison method with position-specific scoring matrix (PSSM) is among the most accurate alignment methods. Currently, cosine similarity and correlation coefficients are used as scoring functions of dynamic programming to calculate similarity between PSSMs. However, it is unclear whether these functions are optimal for profile alignment methods. By definition, these functions cannot capture nonlinear relationships between profiles. Therefore, we attempted to discover a novel scoring function, which was more suitable for the profile-comparison method than existing functions, using neural networks. Results: Although neural networks required derivative-of-cost functions, the problem being addressed in this study lacked them. Therefore, we implemented a novel derivative-free neural network by combining a conventional neural network with an evolutionary strategy optimization method used as a solver. Using this novel neural network system, we optimized the scoring function to align remote sequence pairs. Our results showed that the pairwise-profile aligner using the novel scoring function significantly improved both alignment sensitivity and precision relative to aligners using existing functions. Conclusions: We developed and implemented a novel derivative-free neural network and aligner (Nepal) for optimizing sequence alignments. Nepal improved alignment quality by adapting to remote sequence alignments and increasing the expressiveness of similarity scores. Additionally, this novel scoring function can be realized using a simple matrix operation and easily incorporated into other aligners. Moreover our scoring function could potentially improve the performance of homology detection and/or multiple-sequence alignment of remote homologous sequences. The goal of the study was to provide a novel scoring function for profile alignment method and develop a novel learning system capable of addressing derivative-free problems. Our system is capable of optimizing the performance of other sophisticated methods and solving problems without derivative-of-cost functions, which do not always exist in practical problems. Our results demonstrated the usefulness of this optimization method for derivative-free problems. PMID- 29467817 TI - Mental health literacy: what do Nigerian adolescents know about depression? AB - Background: Depression is a leading cause of disability and has been projected to become the 2nd most burdensome disease by the year 2020; depression has also been found to be the strongest single risk factor for attempted or completed suicides. Adolescent-onset mood disorders are frequently unrecognized or misdiagnosed and often go untreated. While there is a growing literature on the mental health literacy of adults, there has not been a parallel interest in the mental health literacy of young people in Nigeria. Methods: The study was a cross-sectional descriptive survey conducted among students of a Federal Government College (high school) in south-east Nigeria. All consenting students in the senior secondary classes (grades 10-12) were recruited, making a total of 285 participants. The participants were presented with the 'friend in need' questionnaire designed to elicit the participants' recognition of the disorder depicted in two vignettes and their recommendation about the appropriate source of help-seeking. One vignette was of a clinically depressed case while the other vignette was about a girl undergoing normal life crisis. Results: Out of the 285 students recruited into the study, 277 questionnaires were adequately completed indicating a response rate of 97.2%. A total of 4.8% (n = 13) participants correctly identified and labelled the depression vignette. Only four respondents (1.5%) recommended professional help from a Psychiatrist or Psychologist. Insomnia was the most identified symptom of distress for depression (17.1%). Females demonstrated higher mental health literacy, in terms of their ability to correctly label the depression vignettes, their expression of greater concern over a depressed peer than males, their expectation that depression requires a longer recovery than normal teenage problems and in their ability to identify individual symptoms of depression. Family and friends were the most recommended source of help. Conclusion: Mental health literacy was abysmally low amongst the adolescents surveyed. There's an urgent need to increase mental health awareness in Nigeria. PMID- 29467816 TI - Advanced gallbladder inflammation is a risk factor for gallbladder perforation in patients with acute cholecystitis. AB - Background: Acute perforated cholecystitis (APC) is probably the most severe benign gallbladder pathology with high rates of morbidity and mortality. The cause of APC has not been fully understood. We postulated that APC is a complication of advanced gallbladder inflammation. The aim of this study was to investigate the extent of gallbladder inflammation in patients with APC. Methods: Patients with intraoperative and histopathologic diagnosis of APC were compared with cases with acute cholecystitis without perforation with respect to the extent of inflammation on histopathology as well as surgical outcomes. Results: Fifty patients with APC were compared to 150 cases without perforation. Advanced age > 65 years and elevated CRP were confirmed on multivariate analysis as independent risk factors for APC. Advanced gallbladder inflammation was seen significantly more often in patients with APC (84.0 vs. 18.7%). Surgery lasted significantly longer 131.3 +/- 55.2 min vs. 100.4 +/- 47.9 min; the rates of conversion (22 vs. 4%), morbidity (24 vs. 7%), and mortality (8 vs. 1%) were significantly higher in patients with APC. ICU management following surgery was needed significantly more often in the APC group (56 vs. 15%), and the overall length of stay (11.2 +/- 12.0 days vs. 5.8 +/- 6.5 days) was significantly longer compared to the group without perforation. Conclusion: Acute gallbladder perforation in patients with acute cholecystitis represents the most severe complication of cholecystitis. Acute perforated cholecystitis is a sequela of advanced gallbladder inflammation like empyematous and gangrenous cholecystitis and is associated with poor outcome compared to non-perforated cases. PMID- 29467818 TI - Knowledge transfer: a worldwide challenge in child mental health: a recommendation to the readership of CAPMH concerning the revised version of the IACAPAP Textbook of Child and Adolescent Mental Health. AB - Background: Transfer of knowledge is an important issue throughout all scientific disciplines, especially in the medical and psycho-social field. The issue of worldwide knowledge transfer in child mental health is one of the aims and goals of the journal Child and Adolescent Psychiatry and Mental Health (CAPMH). The demand for mental health training is high worldwide, and especially in low- to lower-middle income countries, where inadequate access to knowledge resources in the field of child and adolescent mental health (CAMH) is prevalent. At the same time, many of these countries are showing an increased risk for mental health issues in children and adolescents. The International Association for Child and Adolescent Psychiatry and Allied Professions (IACAPAP) Textbook of Child and Adolescent Mental Health counters this problem. It is an open-access e-textbook aiming to provide an overview of current and established treatment and practical approaches for child and adolescent psychiatrists, psychotherapists and allied (mental health) professionals worldwide. First published in 2012, the updated and revised version was launched in 2015. The aim of this commentary is to review and disseminate the usefulness and practicability of content and further material included in the new version of the textbook. Review: Overall, the textbook contains ten sections divided into 59 chapters, with a total of 1435 pages. The original version of the textbook was written in English. The revised version contains translations of 49 chapters into different languages (to date French, Spanish, Hebrew, Arabic, Portuguese, Russian, Norwegian and/or Japanese), with additional material for knowledge dissemination and self-directed learning (e.g. videos and quizzes) for several chapters. The textbook and the add-on materials for dissemination are of high quality and convey a great introduction to important topics concerning mental health. Apart from knowledge transfer, there is a pragmatic focus on clinical practice and on regional and cultural differences. Conclusion: The textbook is a new and unique opportunity for professionals all over the world to improve their knowledge, skills and expertise in CAMH. High-quality, up-to-date and freely accessible materials in the field of CAMH are combined with the opportunity to share insights with colleagues. PMID- 29467819 TI - Real-time imaging reveals that lytic polysaccharide monooxygenase promotes cellulase activity by increasing cellulose accessibility. AB - Background: The high cost of enzymes is one of the key technical barriers that must be overcome to realize the economical production of biofuels and biomaterials from biomass. Supplementation of enzyme cocktails with lytic polysaccharide monooxygenase (LPMO) can increase the efficiency of these cellulase mixtures for biomass conversion. The previous studies have revealed that LPMOs cleave polysaccharide chains by oxidization of the C1 and/or C4 carbons of the monomeric units. However, how LPMOs enhance enzymatic degradation of lignocellulose is still poorly understood. Results: In this study, we combined enzymatic assays and real-time imaging using atomic force microscopy (AFM) to study the molecular interactions of an LPMO [TrAA9A, formerly known as TrCel61A) from Trichoderma reesei] and a cellobiohydrolase I (TlCel7A from T. longibrachiatum) with bacterial microcrystalline cellulose (BMCC) as a substrate. Cellulose conversion by TlCel7A alone was enhanced from 46 to 54% by the addition of TrAA9A. Conversion by a mixture of TlCel7A, endoglucanase, and beta glucosidase was increased from 79 to 87% using pretreated BMCC with TrAA9A for 72 h. AFM imaging demonstrated that individual TrAA9A molecules exhibited intermittent random movement along, across, and penetrating into the ribbon-like microfibril structure of BMCC, which was concomitant with the release of a small amount of oxidized sugars and the splitting of large cellulose ribbons into fibrils with smaller diameters. The dividing effect of the cellulose microfibril occurred more rapidly when TrAA9A and TlCel7A were added together compared to TrAA9A alone; TlCel7A alone caused no separation. Conclusions: TrAA9A increases the accessible surface area of BMCC by separating large cellulose ribbons, and thereby enhances cellulose hydrolysis yield. By providing the first direct observation of LPMO action on a cellulosic substrate, this study sheds new light on the mechanisms by which LPMO enhances biomass conversion. PMID- 29467821 TI - Function analysis of 5'-UTR of the cellulosomal xyl-doc cluster in Clostridium papyrosolvens. AB - Background: Anaerobic, mesophilic, and cellulolytic Clostridium papyrosolvens produces an efficient cellulolytic extracellular complex named cellulosome that hydrolyzes plant cell wall polysaccharides into simple sugars. Its genome harbors two long cellulosomal clusters: cip-cel operon encoding major cellulosome components (including scaffolding) and xyl-doc gene cluster encoding hemicellulases. Compared with works on cip-cel operon, there are much fewer studies on xyl-doc mainly due to its rare location in cellulolytic clostridia. Sequence analysis of xyl-doc revealed that it harbors a 5' untranslated region (5'-UTR) which potentially plays a role in the regulation of downstream gene expression. Here, we analyzed the function of 5'-UTR of xyl-doc cluster in C. papyrosolvens in vivo via transformation technology developed in this study. Results: In this study, we firstly developed an electrotransformation method for C. papyrosolvens DSM 2782 before the analysis of 5'-UTR of xyl-doc cluster. In the optimized condition, a field with an intensity of 7.5-9.0 kV/cm was applied to a cuvette (0.2 cm gap) containing a mixture of plasmid and late cell suspended in exponential phase to form a 5 ms pulse in a sucrose-containing buffer. Afterwards, the putative promoter and the 5'-UTR of xyl-doc cluster were determined by sequence alignment. It is indicated that xyl-doc possesses a long conservative 5'-UTR with a complex secondary structure encompassing at least two perfect stem-loops which are potential candidates for controlling the transcriptional termination. In the last step, we employed an oxygen-independent flavin-based fluorescent protein (FbFP) as a quantitative reporter to analyze promoter activity and 5'-UTR function in vivo. It revealed that 5'-UTR significantly blocked transcription of downstream genes, but corn stover can relieve its suppression. Conclusions: In the present study, our results demonstrated that 5'-UTR of the cellulosomal xyl-doc cluster blocks the transcriptional activity of promoter. However, some substrates, such as corn stover, can relieve the effect of depression of 5'-UTR. Thus, it is speculated that 5'-UTR of xyl-doc was a putative riboswitch to regulate the expression of downstream cellulosomal genes, which is helpful to understand the complex regulation of cellulosome. PMID- 29467820 TI - Genomic comparison of Clostridium species with the potential of utilizing red algal biomass for biobutanol production. AB - Background: Sustainable biofuels, which are widely considered as an attractive alternative to fossil fuels, can be generated by utilizing various biomass from the environment. Marine biomass, such as red algal biomass, is regarded as one potential renewable substrate source for biofuels conversion due to its abundance of fermentable sugars (e.g., galactose). Previous studies focused on the enhancement of biofuels production from different Clostridium species; however, there has been limited investigation into their metabolic pathways, especially on the conversion of biofuels from galactose, via whole genomic comparison and evolutionary analysis. Results: Two galactose-utilizing Clostridial strains were examined and identified as Clostridium acetobutylicum strain WA and C. beijerinckii strain WB. Via the genomic sequencing of both strains, the comparison of the whole genome together with the relevant protein prediction of 33 other Clostridium species was established to reveal a clear genome profile based upon various genomic features. Among them, five representative strains, including C. beijerinckii NCIMB14988, C. diolis DSM 15410, C. pasteurianum BC1, strain WA and WB, were further discussed to demonstrate the main differences among their respective metabolic pathways, especially in their carbohydrate metabolism. The metabolic pathways involved in the generation of biofuels and other potential products (e.g., riboflavin) were also reconstructed based on the utilization of marine biomass. Finally, a batch fermentation process was performed to verify the fermentative products from strains WA and WB using 60 g/L of galactose, which is the main hydrolysate from algal biomass. It was observed that strain WA and WB could produce up to 16.98 and 12.47 g/L of biobutanol, together with 21,560 and 10,140 mL/L biohydrogen, respectively. Conclusions: The determination of the production of various biofuels by both strains WA and WB and their genomic comparisons with other typical Clostridium species on the analysis of various metabolic pathways was presented. Through the identification of their metabolic pathways, which are involved in the conversion of galactose into various potential products, such as biobutanol, the obtained results extend the current insight into the potential capability of utilizing marine red algal biomass and provide a systematic investigation into the relationship between this genus and the generation of sustainable bioenergy. PMID- 29467822 TI - Tension wood structure and morphology conducive for better enzymatic digestion. AB - Background: Tension wood is a type of reaction wood in response to bending or leaning stem as a corrective growth process. Tension wood is formed by both natural and man-made processes. Most attractively, tension wood contains higher glucan content and undergoes higher enzymatic conversion to fermentable sugars. Here, we have employed structural techniques, small-angle neutron scattering (SANS) and wide-angle X-ray diffraction (WAXD) to elucidate structural and morphological aspects of tension wood conducive to higher sugar yields. Results: Small-angle neutron scattering data exhibited a tri-modal distribution of the fibril cross-sectional dimension. The smallest size, 22 A observed in all samples concurred with the WAXD results of the control and opposite side samples. This smallest and the most abundant occurring size was interpreted as the cellulose elementary microfibril diameter. The intermediate size of 45 A, which is most pronounced in the tension side sample and consistent with WAXD results for tension side sample, indicates association of neighboring elementary microfibrils to form larger crystallite bundles. The largest size 61 A observed by SANS was however not observed by WAXD and therefore associated to mesopores. Conclusions: Structure and morphology of tension wood is different from control wood. Cellulose crystallinity increases, lignin content is lower and the appearance of mesopores with 61 A diameter is observed. Despite the presence of higher crystalline cellulose content in tension side, the lower lignin content and may be combined with the abundance of mesopores, substantially improves enzyme accessibility leading to higher yields in cellulose digestion.

AB - Background: Balanced reciprocal translocation is usually an exchange of two terminal segments from different chromosomes without phenotypic effect on the carrier while leading to increased risk of generating unbalanced gametes. Here we describe a four-generation family in Shandong province of China with at least three patients sharing severe intellectual disability and developmental delay resulting from a derivative chromosome 22 originating from a balanced translocation (3;22) involving chromosomes 3q28q29 and 22q13.3. Methods: The proband and his relatives were detected by using karyotyping, chromosome microarray analysis, fluorescent in situ hybridization and real-time qPCR. Results: The proband, a 17 month-old boy, presented with severe intellectual disability, developmental delay, specific facial features and special posture of hands. Pedigree analysis showed that there were at least three affected patients. The proband and other two living patients manifested similar phenotypes and were identified to have identically abnormal cytogenetic result with an unbalanced translocation of 9.0 Mb duplication at 3q28q29 and a 1.7Mb microdeletion at 22q13.3 by karyotyping and chromosome microarray analysis. His father and other five relatives had a balanced translocation of 3q and 22q. Fluorescence in situ hybridization and real-time qPCR definitely validated the results. Conclusions: The abnormal phenotypes of the proband and his two living members in four generations of the family confirmed the 3q duplication and 22q13.3 deletion inherited from familial balanced translocation. This is the first report of familial balanced reciprocal translocation involving chromosomes 3q28q29 and 22q13.3 segregating through four generations.

AB - Background: Xyloglucan (XyG) is a ubiquitous and fundamental polysaccharide of plant cell walls. Due to its structural complexity, XyG requires a combination of backbone-cleaving and sidechain-debranching enzymes for complete deconstruction into its component monosaccharides. The soil saprophyte Cellvibrio japonicus has emerged as a genetically tractable model system to study biomass saccharification, in part due to its innate capacity to utilize a wide range of plant polysaccharides for growth. Whereas the downstream debranching enzymes of the xyloglucan utilization system of C. japonicus have been functionally characterized, the requisite backbone-cleaving endo-xyloglucanases were unresolved. Results: Combined bioinformatic and transcriptomic analyses implicated three glycoside hydrolase family 5 subfamily 4 (GH5_4) members, with distinct modular organization, as potential keystone endo-xyloglucanases in C. japonicus. Detailed biochemical and enzymatic characterization of the GH5_4 modules of all three recombinant proteins confirmed particularly high specificities for the XyG polysaccharide versus a panel of other cell wall glycans, including mixed-linkage beta-glucan and cellulose. Moreover, product analysis demonstrated that all three enzymes generated XyG oligosaccharides required for subsequent saccharification by known exo-glycosidases. Crystallographic analysis of GH5D, which was the only GH5_4 member specifically and highly upregulated during growth on XyG, in free, product-complex, and active site affinity-labelled forms revealed the molecular basis for the exquisite XyG specificity among these GH5_4 enzymes. Strikingly, exhaustive reverse-genetic analysis of all three GH5_4 members and a previously biochemically characterized GH74 member failed to reveal a growth defect, thereby indicating functional compensation in vivo, both among members of this cohort and by other, yet unidentified, xyloglucanases in C. japonicus. Our systems-based analysis indicates distinct substrate-sensing (GH74, GH5E, GH5F) and attack-mounting (GH5D) functions for the endo-xyloglucanases characterized here. Conclusions: Through a multi-faceted, molecular systems-based approach, this study provides a new insight into the saccharification pathway of xyloglucan utilization system of C. japonicus. The detailed structural-functional characterization of three distinct GH5_4 endo-xyloglucanases will inform future bioinformatic predictions across species, and provides new CAZymes with defined specificity that may be harnessed in industrial and other biotechnological applications.

The practice of EC involves the tuning of many parameters, such as population size, generation count, selection size, and crossover and mutation rates. Through an extensive series of experiments over multiple evolutionary algorithm implementations and 25 problems we show that parameter space tends to be rife with viable parameters, at least for the problems studied herein. We discuss the implications of this finding in practice for the researcher employing EC. PMID- 29467826 TI - A novel joint analysis framework improves identification of differentially expressed genes in cross disease transcriptomic analysis. AB - Motivation: Detecting differentially expressed (DE) genes between disease and normal control group is one of the most common analyses in genome-wide transcriptomic data. Since most studies don't have a lot of samples, researchers have used meta-analysis to group different datasets for the same disease. Even then, in many cases the statistical power is still not enough. Taking into account the fact that many diseases share the same disease genes, it is desirable to design a statistical framework that can identify diseases' common and specific DE genes simultaneously to improve the identification power. Results: We developed a novel empirical Bayes based mixture model to identify DE genes in specific study by leveraging the shared information across multiple different disease expression data sets. The effectiveness of joint analysis was demonstrated through comprehensive simulation studies and two real data applications. The simulation results showed that our method consistently outperformed single data set analysis and two other meta-analysis methods in identification power. In real data analysis, overall our method demonstrated better identification power in detecting DE genes and prioritized more disease related genes and disease related pathways than single data set analysis. Over 150% more disease related genes are identified by our method in application to Huntington's disease. We expect that our method would provide researchers a new way of utilizing available data sets from different diseases when sample size of the focused disease is limited. PMID- 29467827 TI - Advanced imaging techniques for small bowel Crohn's disease: what does the future hold? AB - Treatment of Crohn's disease (CD) is intrinsically reliant on imaging techniques, due to the preponderance of small bowel disease and its transmural pattern of inflammation. Ultrasound (US), computed tomography (CT) and magnetic resonance imaging (MRI) are the most widely employed imaging methods and have excellent diagnostic accuracy in most instances. Some limitations persist, perhaps the most clinically relevant being the distinction between inflammatory and fibrotic strictures. In this regard, several methodologies have recently been tested in animal models and human patients, namely US strain elastography, shear wave elastography, contrast-enhanced US, magnetization transfer MRI and contrast dynamics in standard MRI. Technical advances in each of the imaging methods may expand their indications. The addition of oral contrast to abdominal US appears to substantially improve its diagnostic capabilities compared to standard US. Ionizing dose-reduction methods in CT can decrease concern about cumulative radiation exposure in CD patients and diffusion-weighted MRI may reduce the need for gadolinium contrast. Clinical indexes of disease activity and severity are also increasingly relying on imaging scores, such as the recently developed Lemann Index. In this review we summarize some of the recent advances in small bowel CD imaging and how they might affect clinical practice in the near future. PMID- 29467828 TI - Age-related differences in foot mobility in individuals with patellofemoral pain. AB - Background: Age-related changes in midfoot mobility have the potential to influence success with foot orthoses intervention in people with patellofemoral pain (PFP). The aim of this study was to determine whether older people with PFP demonstrate less foot mobility than younger adults with PFP. Methods: One hundred ninety four participants (113 (58%) women, age 32 +/- 7 years, BMI 25 +/- 4.9 kg/m2) with PFP (>= 6 weeks duration) were included, with foot mobility quantified using reliable and valid methods. K-means cluster analysis classified participants into three homogenous groups based on age. After cluster formation, univariate analyses of co-variance (covariates: sex, weight) were used to compare midfoot height mobility, midfoot width mobility, and foot mobility magnitude between age groups (significance level 0.05). Results: Cluster analysis revealed three distinct age groups: 18-29 years (n = 70); 30-39 years (n = 101); and 40-50 years (n = 23). There was a significant main effect for age for midfoot height mobility (p < 0.001) and foot mobility magnitude (p = 0.006). Post-hoc analyses revealed that midfoot height mobility differed across all three groups (moderate to large effect sizes), and that foot mobility magnitude was significantly less in those aged 40-50 years compared to those aged 18-25 years (moderate effect size). There were no significant main effects for age for midfoot width mobility (p > 0.05). Conclusion: Individuals with PFP aged 40-50 years have less foot mobility than younger adults with PFP. These findings may have implications for evaluation and treatment of older individuals with PFP. PMID- 29467829 TI - Surgical offloading procedures for diabetic foot ulcers compared to best non surgical treatment: a study protocol for a randomized controlled trial. AB - Background: Diabetic foot ulcers are frequently related to elevated pressure under a bony prominence. Conservative treatment includes offloading with orthopaedic shoes and custom made orthotics or plaster casts. While casting in plaster is usually effective in achieving primary closure of foot ulcers, recurrence rates are high. Minimally invasive surgical offloading that includes correction of foot deformities has good short and long term results. The surgery alleviates the pressure under the bony prominence, thus enabling prompt ulcer healing, negating the patient's dependence on expensive shoes and orthotics, with a lower chance of recurrence. The purpose of this protocol is to compare offloading surgery (percutaneous flexor tenotomy, mini-invasive floating metatarsal osteotomy or Keller arthroplasty) to non-surgical treatment for patients with diabetic foot ulcers in a semi-crossover designed RCT. Methods: One hundred patients with diabetic neuropathy related foot ulcers (tip of toe ulcers, ulcers under metatarsal heads and ulcers under the hallux interphalangeal joint) will be randomized (2:3) to a surgical offloading procedure or best available non surgical treatment. Group 1 (surgery) will have surgery within 1 week. Group 2 (controls) will be prescribed an offloading cast applied for up to 12 weeks (based on clinical considerations). Following successful offloading treatment (ulcer closure with complete epithelization) patients will be prescribed orthopaedic shoes and custom made orthotics. If offloading by cast for at least 6 weeks fails, or the ulcer recurs, patients will be offered surgical offloading. Follow-up will take place till 2 years following randomization. Outcome criteria will be time to healing of the primary ulcer (complete epithelization), time to healing of surgical wound, recurrence of ulcer, time to recurrence and complications. Discussion: The high recurrence rate of foot ulcers and their dire consequences justify attempts to find better solutions than the non-surgical options available at present. To promote surgery, RCT level evidence of efficacy is necessary. Trial registration: Israel MOH_2017-08-10_000719. NIH: NCT03414216. PMID- 29467830 TI - Risk perception of cardiovascular diseases among individuals with hypertension in rural Malaysia. AB - Objective: Despite various efforts, hypertension remains poorly controlled, thus allowing cardiovascular disease (CVD) to impact the health burden worldwide. Patients' perception of risk may contribute to this scenario. The present study aims to assess the level of risk perception among individuals with hypertension in rural Malaysia. Methods: This is a community-based study conducted among adults between 2010 and 2011 among a rural population in Raub, Pahang, Malaysia. Blood pressure was measured after 5 min of rest. Measurement was done twice and the average was recorded. Cardiovascular risk perception score (CvRPS) was derived using the Modified Risk and Health Behavior Questionnaire. Higher CvRPS indicates the respondent perceives a poorer prognostic outlook. Results: A total of 383 respondents who have hypertension participated in this study. The mean age of respondents was 62+/-10.6 years; men 63.1+/-9.6 years, women 61.2+/-11.1 years (p>0.05). Among hypertensives, those who were not on medication had significantly lower CvRPS compared with those who were on medications (115.9+/-22.1vs 120.9+/ 23.5, p=0.036); those who were not aware of their hypertensive status had significantly lower CvRPS compared with respondents who were aware about their hypertension (116.7+/-22.5vs 121.7+/-21.3, p=0.029) and those with uncontrolled hypertension had significantly lower CvRPS compared with those whose blood pressure was controlled (118.2+/-22.2vs 128.8+/-25.8, p=0.009). Conclusions: Our study shows that respondents who were not on medications, unaware of their hypertension status and those who had uncontrolled hypertension tended to underestimate (lower CvRPS) their risk for CVD. Improving their CvPRS through a concerted health education may lead to better therapeutic behaviour and outcomes. PMID- 29467831 TI - Non-compaction of left ventricular myocardium in sub-Saharan African adults. AB - Background: Non-compaction of the left ventricle (NCLV) is an unclassified cardiomyopathy due to intrauterine arrest of compaction of the loose interwoven meshwork. Only a few studies involving sub-Saharan Africans insmall numbers have been published. The aim of our study was to determine the diagnostic, therapeutic and prognostic aspects as well as the clinical course of NCLV in a black African population. Methodology: A multicentre retrospective study was carried out between November 2007 and June 2012 in two cardiology departments in Dakar. Patients who met the echocardiographic criteria for NCLV were included in the study. Results: 35patients with the diagnosis of NCLV were evaluated in the study. Their mean age was 47+/-18.4 years. Heart failure was found in 77.1% of the patients. The most frequent electrocardiographic abnormalities were left ventricular hypertrophy (LVH) (46%) and sinus tachycardia (43%). Mean non compaction/compaction ratio was 2.84+/-0.68 with preferential localization in the apex of the left ventricle. The main complications observed were cardiogenic shock (23.5%), pulmonary embolism (6.3%) and ventricular tachycardia (5.9%). Diuretics and ACE inhibitors were the medications most often prescribed. Age >60 years (p=0.04), male gender (p=0.03) and the occurrence of complications during follow-up (p=0.04) were noted to be predictors of poor prognosis. Conclusion: Contrary to previous beliefs, NCLV may not be less common in black Africans than in other ethnic subgroups. Clinicians in Africa should be made aware of NCLV so that it can be diagnosed at earlier stages. PMID- 29467832 TI - Implications of prescribing a fixed-dose combination in clinical cardiology practice: a retrospective observational study using a single medical centre database in Korea. AB - Objective: Fixed-dose combination (FDC) prescribing enhances adherence to medication. However, there are limited data regarding the usefulness of FDC drugs across different risk groups. The aim of this study was to explore the relationship between FDC discontinuation and clinical outcomes. Methods: From January 2008 to December 2014, patients with FDC prescriptions who visited a cardiology outpatient clinic at a tertiary university hospital in Daegu, Republic of Korea were retrospectively identified. The 10-year atherosclerotic cardiovascular disease (ASCVD) risk score and 20 conventional cardiovascular (CV) risk factors were assessed. Patients were classified according to FDC continuation, together with a tertile of 20 risks. CV events were defined as the composite of admission for worsening heart failure or diabetes, stroke, ischaemic heart disease, and CV death. Results: 502 patients were prescribed with one of the following FDC products: calcium channel blocker (CCB) plus angiotensin receptor blockers (ARB), CCB plus statins, and ARB plus diuretics. During follow up (mean 2.8+/-2.4 years), 203 discontinuations (40.4%) occurred. FDC discontinued patients had lower ASCVD risk scores (24.8% vs. 28.8%, p<0.001), and patients with <6 risk factors discontinued FDC frequently. During follow-up, 57 events (11.4%) were reported: 30 (14.8%) in FDC-discontinued patients and 27 (9.1%) in FDC-continued patients (p=0.062). In multivariate models accounting for events, FDC discontinuation (p<0.001) and high ASCVD risk score (p=0.017) were associated with CV events. Conclusions: FDC discontinuation was common among patients attending the cardiology outpatient clinic. Our analyses suggest that FDC discontinuation in patients at high ASCVD risk may have an impact on CV event rates. PMID- 29467833 TI - Cardiovascular risk in an HIV-infected population in India. AB - Objective: To characterise prevalence of traditional cardiovascular disease (CVD) risk factors, assess CVD risk and examine the effect of simulated interventions on CVD risk among HIV-infected Asian Indians. Methods: Cross-sectional data between September 2015 and July 2016 wer used to describe the prevalence of CVD risk factors. Five risk scores (Framingham, Data Collection on Adverse Effects of Anti-HIV Drugs Study (D:A:D), Atherosclerotic Cardiovascular, QRISK2 and Ramathibodi-Electricity Generating Authority of Thailand were used to estimate CVD risk. The effect of seven sensitivity analyses: smoking prevention; diabetes prevention; optimal blood pressure and dyslipidaemia control (total cholesterol, high-density lipoprotein (HDL)); CD4 augmentation and a combination of the scenarios on the median cumulative D:A:D CVD scores were assessed. Results: Of 402 enrolled, 56% were women, median age was 40 years (IQR: 35-45 years) and median time-updated CD4 counts were 378 cells/MUL (IQR: 246-622). Fifty-five and 28% had ever been screened for hypertension and diabetes, respectively prior to enrolment. The prevalence of diabetes, hypertension, hypercholesterolaemia, low HDL, previous and current smokers were 9%, 22%, 20%, 39%, 14% and 4%, respectively. Thirty-six per cent had intermediate-to-high 5-year CVD risk by D:A:D estimates. Thirty-two per cent were eligible for statin therapy by American College of Cardiology/American Heart Association guidelines; 2% were currently on statins. In sensitivity analyses, diabetes prevention was associated with the highest reduction of CVD risk. Conclusion: CVD at younger ages among Asian Indian people living with HIV appear to be an imminent risk for morbidity. Stepping up of preventive services including screening services and prescription of statins are important strategies that must be considered.

PMID- 29467836 TI - An evaluation of the 25 by 25 goal for premature cardiovascular disease mortality in Taiwan: an age-period-cohort analysis, population attributable fraction and national population-based study. AB - Objectives: The aim of the 25 by 25 goal is to reduce mortality from premature non-communicable diseases by 25% before 2025. Studies have evaluated the 25 by 25 goal in many countries, but not in Taiwan. The aim of this study was to estimate the 25 by 25 goal for premature mortality from cardiovascular diseases in Taiwan. Methods: We applied the age-period-cohort model to project the incidence of premature death from cardiovascular disease from 2015 to 2024 and used the population attributable fraction to estimate the contributions of targeted risk factors. The probability of death was used to estimate the percent change. Results: The percent change in business-as-usual trend during 2010-2024 was only a 6% (range 1.7-10.7%) lower risk of premature mortality from cardiovascular disease among men. The greatest reduction in the risk of mortality occurred with a 30% reduction in the prevalence of smoking; however, there was only a 14.5% (10.6-18.3%) decrease in percent change and in the corresponding number of men (3706: range 3543-3868) who were prevented from dying. More than a 25% reduction in the percent change of premature cardiovascular disease mortality among women was achieved without control of any risk factor. To reach a 25% reduction in men before 2025, there needs to be a 70% reduction in the prevalence of smoking to reduce mortality by 26.2% (22.9-29.3%). Conclusions: Cigarette smoking is the primary target in the prevention of cardiovascular disease. Through the stringent control of smoking, the goal of a 25% reduction in premature mortality from cardiovascular disease may be achieved before 2025 in Taiwan. PMID- 29467837 TI - Is white rice consumption a risk for metabolic and cardiovascular outcomes? A systematic review and meta-analysis. AB - Objective: The main objective of this systematic review and meta-analysis was to investigate the association between white rice consumption and risk of metabolic and cardiovascular outcomes. Methods: We conducted a comprehensive search of Medline, Embase, Scopus, and the Cochrane Central Register of Controlled Trials from database inception through March 2016. Original studies that reported associations between white rice consumption and cardiovascular outcomes regardless of study design were selected. We extracted study characteristics and outcome data. Conflicts were resolved through consensus. Using the DerSimonian and Laird random effects models, we calculated pooled relative risks with 95% CI. Results: Our search identified 721 citations. 18 studies were included with a total of 1 777 059 individuals: 14 348 had type 2 diabetes mellitus (T2DM); 5612 had metabolic syndrome (MetS); 10 839 had coronary heart disease (CHD); and 11 698 had stroke. Compared with the lowest category, the highest category of white rice consumption was only associated with 30% higher risk of MetS (pooled OR 1.30, 95% CI 1.03 to 1.65; p<0.001; I2=65.5%). Conclusions: Higher white rice consumption has not been shown to be associated with increased risk of CHD, stroke and T2DM. However, white rice consumption may be associated with increased risk of MetS in certain populations. PMID- 29467838 TI - Pulmonary and right ventricular dysfunction are frequently present in heart failure irrespective of left ventricular ejection fraction. AB - Background: Heart failure (HF) may influence the lungs and vice versa. However, this interaction and the influence on right ventricular function (RVF) are insufficiently described in patients with HF divided into the recent groups based on left ventricular ejection fraction (LVEF): HF with reduced, midrange and preserved ejection fraction (HFrEF, HFmrEF and HFpEF, respectively). Methods: Overall, 186 consecutive stable patients with HF seen in our outpatient clinic were retrospectively divided into HFrEF (n=70), HFmrEF (n=55) and HFpEF (n=61). Airflow limitation and gas exchange disturbance were measured by spirometry (forced expiratory volume in the first second/forced vital capacity (FEV1/FVC) (%)) and diffusion capacity of the lungs for carbon monoxide (DLCO). Standard echocardiography was performed to measure RV structure (RV diameter) and function (tricuspid annular plane systolic excursion/pulmonary artery systolic pressure (TAPSE/PASP)). Correlations were used to assess possible relations between pulmonary dysfunction and measurements of the RV. Results: None of the investigated parameters differed significantly between the three groups (all p>0.1); FEV1/FVC was 70%+/-12%, 70%+/-13% and 74%+/-10% in patients with HFrEF, HFmrEF and HFpEF (p=0.12) and DLCO was 5.7+/-1.6, 5.7+/-1.8 and 5.6+/-1.6 mmol/min/kPa, respectively (p=0.95). RV structure and function did not differ either (TAPSE/PASP 0.58, 0.60 and 0.57, respectively (p=0.84)). There was a correlation of DLCO with RV function (r=0.34, p<0.001). Conclusion: The investigated cardiopulmonary parameters were comparable in the three HF groups. Diffusion capacity was impaired in more than half of the stable HF population independently of the LVEF and showed a correlation with RV function. PMID- 29467839 TI - Outcomes after mitral valve surgery for rheumatic heart disease. AB - Objective: To further the understanding of the factors influencing outcome following rheumatic heart disease (RHD) related mitral valve surgery, which globally remains an important cause of heart disease and a particular problem in Indigenous Australians. Methods: The Australian Cardiac Surgery Database was utilised to assess outcomes following mitral valve repair and replacement for RHD and non-RHD valve disease. The association with aetiology, demographics, comorbidities, preoperative status and operative procedure was evaluated. Results: Mitral valve repairs and replacements undertaken in Australia were analysed from 119 and 1078 RHD surgical procedures and 3279 and 2400 non-RHD procedures, respectively. RHD mitral valve repair, compared with replacement, resulted in a slightly shorter hospital stay and more reoperation for valve dysfunction, but no difference in 30-day survival. In unadjusted survival analysis to 5 years, RHD mitral valve repair and replacement were no different (HR 0.86, 95% CI 0.4 to 1.7), non-RHD repair was superior to replacement (HR 1.7, 95% CI 1.4 to 2.0), RHD and non-RHD repair were no different (HR 0.9, 95% CI 0.5 to 1.7), and RHD replacement was superior to non-RHD (HR 1.5, 95% CI 1.2 to 1.9). None of these differences persisted in adjusted analyses and there was no difference in long-term survival for Indigenous Australians. Conclusion: In this large prospective cohort study we have demonstrated that adjusted long-term survival following RHD mitral valve repair surgery in Australia is no different to replacement and no different to non-RHD. Interpretation of valve surgery outcome requires careful consideration of patient factors that may also influence survival. PMID- 29467840 TI - Prevalence of randomised controlled trials in Japanese cardiovascular journals: a descriptive study. AB - Background: Little is known about the recent proportion and trends of randomised controlled trials (RCTs) published in Japanese cardiovascular journals. Methods and results: This study retrospectively reviewed all original research articles published between 2006 and 2015 in six English-language journals issued by societies related to cardiovascular medicine in Japan. All these journals had been indexed in PubMed for more than 5 years until 2015. We examined the 2-year trends in the prevalence of RCTs, as well as the types of study subjects and interventions investigated. In addition, we applied a multivariable logistic regression analysis to assess the factors related to the publication of RCTs. A total of 7117 articles were eligible for our analyses. The proportion of RCTs among Japanese journals was 3.5% (252/7117). No significant change in the prevalence of RCTs among all included journals was noted (3.8% vs 3.1%, p=0.751). RCTs related to ischaemic heart disease were the most frequently published (85/252, 33.7%). In the multivariable analysis, a male first author (adjusted OR (AOR) 1.97; 95% CI 1.30 to 2.99) and reports from Asia (AOR 1.62; 95% CI 1.19 to 2.21) were significantly associated with the publication of RCTs. Conclusions: In Japanese cardiovascular journals, RCTs accounted for 3.5% of all original research articles published, and there was no change in the prevalence of RCTs during the study period. PMID- 29467841 TI - Hepatoprotective effect of methyl ferulic acid against carbon tetrachloride induced acute liver injury in rats. AB - The present study aimed to investigate the hepatoprotective effects of methyl ferulic acid (MFA) against oxidative stress and apoptosis in acute liver injury induced by carbon tetrachloride (CCl4) in rats, as well as the underlying mechanisms. Sprague Dawley rats were treated with CCl4 after oral administration of MFA (25, 50, and 100 mg/kg) or dimethyl diphenyl bicarboxylate (200 mg/kg) for 7 days. The hepatoprotective effects of MFA were determined by analyzing serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities as well as changes of oxidant parameters. Histopathological analysis was performed to determine the degree of hepatic injury. The mechanisms were investigated by detecting the levels of NADPH oxidase (NOX) trans-membrane subunit NOX4, its ligand p22phox, as well as caspase3, cleaved caspase3, B-cell lymphoma (Bcl)-2, Bcl-2-associated X protein (Bax), tumor necrosis factor (TNF)-alpha, interleukin (IL)-1, reactive oxygen species (ROS), thiobarbituric acid-reactive substances (TBARS), total anti-oxidant capacity (TAC), phosphorylated J-Jun N-terminal kinase (p-JNK) and p-p38 mitogen-activated protein kinase (MAPK) using semi quantitative polymerase chain reaction, western blot analysis and colorimetric assays. MFA treatment significantly decreased serum enzymatic activities of ALT and AST. MFA markedly increased activities of liver superoxide dismutase, catalase and glutathione peroxidase, and reduced the malondialdehyde concentration. Histopathological examination demonstrated that MFA reduced lipid degeneration, cytoplasmic vacuolization, necrosis and inflammatory cell infiltration in the liversof CCl4-treated rats. MFA treatment markedly inhibited the expression of inflammatory factors TNF-alpha and IL-1beta. Mechanistic study revealed that MFA decreased the TAC and the levels of ROS and TBARS. Furthermore, MFA treatment led to a reduction of the mRNA and protein expression of NOX4 and p22phox, as well as the protein levels of caspase3, cleaved caspase-3 and Bax, and an upregulation of p-JNK, p-p38 MAPK and Bcl-2 proteins in the liver. The present study demonstrated that MFA has hepatoprotective effects against CCl4 induced acute liver damage. MFA has anti-oxidant, anti-inflammatory and anti apoptotic activities and was able to modulate the NOX4/p22phox/ROS-JNK/p38 MAPK signaling pathway. PMID- 29467842 TI - Hypoxia-inducible factor-1alpha regulates epithelial-to-mesenchymal transition in paraquat-induced pulmonary fibrosis by activating lysyl oxidase. AB - Pulmonary fibrosis (PF) is one of the most prevalent causes of death following paraquat (PQ) poisoning. As demonstrated in previous studies by the present authors, epithelial-to-mesenchymal transition (EMT) is associated with PQ-induced PF. In addition, hypoxia-inducible factor-1alpha (HIF-1alpha) and lysyl oxidase (LOX) promote EMT following PQ poisoning. However, the association between HIF 1alpha- and LOX-mediated regulation of EMT remains unclear. The present study investigated the association between HIF-1alpha and LOX with regard to PQ-induced EMT. A549 and RLE-6TN cells were treated with PQ, and HIF-1alpha and LOX expression was silenced with short interfering RNAs. Changes in the expression of HIF-1alpha, LOX, beta-catenin and EMT-related makers were detected using real time quantitative polymerase chain reaction, immunofluorescence, and western blotting. HIF-1alpha and LOX were associated with PQ-induced EMT, and their expression levels were significantly increased (P<0.05). LOX expression was significantly decreased following PQ poisoning when HIF-1alpha expression was inhibited (P<0.05). However, the level of HIF-1alpha did not change significantly when LOX was silenced. The expression level of beta-catenin and the degree of EMT were significantly decreased following HIF-1alpha and LOX silencing in both cell lines (P<0.05). The association between HIF-1alpha and LOX in regulating EMT during PQ-induced PF may be unidirectional. HIF-1alpha may regulate PQ-induced EMT through the LOX/beta-catenin pathway. PMID- 29467843 TI - Sirtuin 7 promotes colorectal carcinoma proliferation and invasion through the inhibition of E-cadherin. AB - Sirtuin 7 (Sirt7) is a member of the sirtuin protein family and is implicated in various carcinomas; however, the function of Sirt7 in colorectal carcinoma (CRC) remains unclear. The present study aimed to explore the biological function of Sirt7 in CRC tissues and cell lines, and to investigate the potential underlying mechanism by performing reverse transcription-quantitative polymerase chain reaction analyses, western blot analyses, luciferase reporter assays, cell proliferation and invasion assays. It was demonstrated that Sirt7 presented a higher expression in CRC tissues and cell lines compared with that in normal tissues and cells, and this higher expression was correlated with the tumor size, the tumor, node and metastasis stage and distant metastasis. Knockdown of Sirt7 repressed the proliferation ability of SW620 and HCT116 cells in vitro, while ectopic expression of Sirt7 increased the epithelial-mesenchymal transition and invasion in HT29 and SW480 cells. Notably, these functional effects of Sirt7 were exerted through the repression of E-cadherin. Thus, the data of the present study indicated a novel mechanistic role for Sirt7 as an oncogene in CRC malignancy, and Sirt7 may be a potential therapeutic target. PMID- 29467844 TI - Target therapy of TRIM-14 inhibits osteosarcoma aggressiveness through the nuclear factor-kappaB signaling pathway. AB - Osteosarcoma is the most common cause of cancer-associated mortality and the prognosis is yet to be fully elucidated due to the paucity of effective therapeutic targets that significantly influence the quality of life and mean survival rates of patients with osteosarcoma. Studies have showed that tripartite motif-containing (TRIM)-14 is a member of the TRIM protein family that has a vital role in tumor progression and metastasis and promotes angiogenesis, invasion and apoptotic resistance of bone cancer. In this study, a chimeric antibody targeting TRIM-14 (Chanti-TRIM) was constructed and the molecular mechanism of target therapy for TRIM-14 was investigated in osteosarcoma cells and xenograft mice. The growth, migration and invasion properties of U-2OS cells were analyzed following incubation with 10-160 mg/ml Chanti-TRIM. Apoptosis of U 2OS cells was detected after Chanti-TRIM treatment. Matrix metalloproteinase (MMP)-9-mediated nuclear factor-kappaB (NF-kappaB) signal pathway was analyzed in U-2OS cells treated with Chanti-TRIM. The inhibitory efficacy of Chanti-TRIM was studied in U-2OS-bearing xenograft mice. Our results demonstrated that neutralizing TRIM-14 expression markedly inhibited the growth, migration and invasion of osteosarcoma cells, in vitro and in vivo. We found that TRIM-14 depletion decreased cell viability and induced cells apoptosis in vitro. In addition, we identified Chanti-TRIM inhibited growth and promoted apoptosis induced by cisplatin through MMP-9-mediated NF-kappaB signal pathway. Furthermore, we observed that Chanti-TRIM treatment inhibited osteosarcoma growth in vivo. Histological analysis indicated that apoptotic bodies were increased and NF-kappaB nuclear translocation factors, including Ikkbeta, p65 and IkBalpha, were decreased in tumors treated by Chanti-TRIM. In conclusion, these results showed that Chanti-TRIM markedly inhibited the progression of osteosarcoma, suggesting Chanti-TRIM may be a potential anti-cancer agent that functions via the activation of the NF-kappaB pathway for osteosarcoma. PMID- 29467845 TI - 14-3-3beta exerts glioma-promoting effects and is associated with malignant progression and poor prognosis in patients with glioma. AB - Glioma is a type of tumor that affects the central nervous system. It has been demonstrated that 14-3-3beta, a protein that is mainly concentrated in the brain, serves an important role in tumor regulation. However, the mechanism of action of 14-3-3beta that underlies the pathogenesis of glioma remains to be elucidated. In the present study, 14-3-3beta was silenced by RNA interference in the human glioma cell line U373-MG. Following knockdown of 14-3-3beta, the proliferation, colony formation, cell cycle progression, migration and invasion of U373-MG cells were significantly decreased (P<0.01), whereas cell apoptosis was increased (P<0.01). Furthermore, in a tumor xenograft experiment, silencing 14-3-3beta significantly inhibited the in vivo tumor growth of U373-MG cells (P<0.01). The results demonstrated that 14-3-3beta levels were significantly higher in human glioma tissues compared with normal brain tissues (P<0.01) and high 14-3-3beta expression was significantly associated with advanced pathological grade (P<0.03) and low Karnofsky performance scale (P<0.003). Patients with glioma who had high 14-3-3beta levels had a significantly shorter survival time compared with those with low expression of 14-3-3beta (P=0.031), suggesting that 14-3-3beta may be an effective predictor of the prognosis of patients with glioma. The results of the present study indicate that 14-3-3beta serves an oncogenic role in glioma, suggesting that 14-3-3beta may have potential as a promising therapeutic target for glioma. PMID- 29467846 TI - Asiatic acid attenuates high-fat diet-induced impaired spermatogenesis. AB - Testicular cell apoptosis is associated with impaired spermatogenesis. It has been reported that Asiatic acid (AA) may suppress apoptosis. However, little is known about the effect of AA on high-fat diet (HFD)-induced impairment of spermatogenesis. The aim of the present study was to determine whether AA protects against HFD-induced impairment of spermatogenesis. Sprague-Dawley rats were randomly divided into three groups: Control group, HFD group and AA (50 mg/kg) + HFD group. Rats fed an HFD were orally administered with AA (50 mg/kg) daily for 12 weeks, and blood samples, testis and epididymis were harvested for further analysis. Sex hormones were detected and hematoxylin and eosin staining was performed to examine the morphological changes of the testis. Semen samples were collected to evaluate sperm quality and apoptosis was determined. The results indicate that AA treatment significantly increased testis weight, testis/body weight, spermatogonia, Leydig cells and Sertoli cells in the testis of obese mice (P<0.05). AA treatment also attenuated HFD-induced histological change. AA treatment prevented HFD-induced decrease of sex hormones and the quality of semen samples (P<0.05). Furthermore, HFD-induced apoptosis was significantly attenuated by AA treatment (P<0.05). In conclusion, the results suggest that AA is able to ameliorate HFD-induced impaired spermatogenesis via inhibiting apoptosis in Sprague-Dawley rats. AA may have therapeutic value in the treatment of obesity-related impairment of spermatogenesis. PMID- 29467847 TI - miRNA-223-3p regulates NLRP3 to promote apoptosis and inhibit proliferation of hep3B cells. AB - Hepatocellular carcinoma (HCC) is a major malignant tumor type with a high incidence and mortality. Infection with hepatitis virus is a high-risk factor. Previous studies have demonstrated that microRNA (miR)-223 was downregulated in HCC tissues. NOD-like receptor family, pyrin domain containing 3 (NLRP3)-is a potential target of miR-223 and has a vital role in hepatitis infection. The present study was performed to investigate the role of miR-223 in the proliferation and apoptosis of HCC cells through regulating NLRP3. A dual luciferase reporter assay was performed to confirm the direct interaction between miR-223-3p and the 3' untranslated region of NLRP3 mRNA. Hep3B cells were then transfected with miR-223 mimics and the proliferation and apoptosis were determined by an MTT and a flow cytometric assay, respectively. The expression of NLRP3 and caspase-1 was analyzed at the mRNA as well as at the protein level by reverse transcription-quantitative polymerase chain reaction and western blot analysis, respectively. The secretion of interleukin (IL)-1beta and IL-18 in the culture supernatants was measured by ELISA. The dual luciferase assay confirmed NLRP3 as a direct target of miR-223. Overexpression of miR-223 in hep3B cells significantly suppressed cell proliferation and promoted apoptosis. Furthermore, the expression of NLRP3 was downregulated by miR-223 transfection. Certain downstream factors of the NLRP3 pathway were also downregulated following overexpression of miR-223. Caspase-1 was decreased at the transcriptional level and the cleaved caspase-1 was decreased at the protein level. Secretion of IL 1beta and IL-18 into the culture medium by cells transfected with miR-223 was lower than that by the control cells. In conclusion, the tumor suppressor role of miR-223 was associated with the regulation of NLRP3 inflammasome components. miR 223 inhibited HCC cell proliferation and promoted apoptosis by directly targeting NLRP3. Downstream production of caspase-1, IL-1beta and IL-18 were also repressed by miR-223. These results provided insight into the association between the innate immune system and the genesis of HCC. PMID- 29467848 TI - Differential microRNA expression in the prefrontal cortex of mouse offspring induced by glyphosate exposure during pregnancy and lactation. AB - Glyphosate is the active ingredient in numerous herbicide formulations. The role of glyphosate in neurotoxicity has been reported in human and animal models. However, the detailed mechanism of the role of glyphosate in neuronal development remains unknown. Recently, several studies have reported evidence linking neurodevelopmental disorders (NDDs) with gestational glyphosate exposure. The current group previously identified microRNAs (miRNAs) that are associated with the etiology of NDDs, but their expression levels in the developing brain following glyphosate exposure have not been characterized. In the present study, miRNA expression patterns were evaluated in the prefrontal cortex (PFC) of 28 postnatal day mouse offspring following glyphosate exposure during pregnancy and lactation. An miRNA microarray detected 55 upregulated and 19 downregulated miRNAs in the PFC of mouse offspring, and 20 selected deregulated miRNAs were further evaluated by quantitative polymerase chain reaction (PCR). A total of 11 targets of these selected deregulated miRNAs were analyzed using bioinformatics. Gene Ontology (GO) terms associated with the relevant miRNAs included neurogenesis (GO:0050769), neuron differentiation (GO:0030182) and brain development (GO:0007420). The genes Cdkn1a, Numbl, Notch1, Fosl1 and Lef1 are involved in the Wnt and Notch signaling pathways, which are closely associated with neural development. PCR arrays for the mouse Wnt and Notch signaling pathways were used to validate the effects of glyphosate on the expression pattern of genes involved in the Wnt and Notch pathways. Nr4a2 and Wnt7b were downregulated, while Dkk1, Dixdc1, Runx1, Shh, Lef-1 and Axin2 were upregulated in the PFC of mice offspring following glyphosate exposure during pregnancy and lactation. These results indicated abnormalities of the Wnt/beta-catenin and Notch pathways. These findings may be of particular interest for understanding the mechanism of glyphosate-induced neurotoxicity, as well as helping to clarify the association between glyphosate and NDDs. PMID- 29467849 TI - Efficacy and survival rate of intensity-modulated radiotherapy combined with chemotherapy for elderly patients with locally advanced oropharyngeal cancer. AB - The efficacy of intensity-modulated radiotherapy (IMRT) combined with chemotherapy in the treatment of elderly patients with locally advanced oropharyngeal cancer and its effect on survival rate were studied. Elderly patients (n=150) diagnosed with locally advanced oropharyngeal cancer by histopathology were selected and randomly divided into the observation group (n=75) and the control group (n=75). Patients in the observation group were treated with IMRT combined with chemotherapy, while those in the control group were treated with conventional radiotherapy and chemotherapy. The two groups were treated with docetaxel + cisplatin (TP regimen). All patients received 1 to 2 cycles of docetaxel + cisplatin-induced chemotherapy, and after the radiotherapy began, the chemotherapy with docetaxel was synchronously conducted. The recent efficacy (tumor regression condition was observed at 3 months after the treatment), 1-year, 3-year and 5-year overall survival (OS), local-regional control (LRC), progression-free survival (PFS), disease-free survival (DFS) and the incidence rate of adverse reactions of patients in the two groups were compared. In the observation group, 73 patients completed the radiotherapy and chemotherapy, while all the patients in the control group completed the treatments. The 1-year OS of the observation group and the control group was 97.3 and 85.3%, respectively. In the observation group, the 3-year LRC, OS, PFS and DFS of the observation group was 94.5, 91.8, 90.4 and 87.7%, respectively; the 5 year LRC, OS, PFS and DFS was 64.4, 56.2, 56.2 and 54.8%, respectively. In the control group, the 3-year LRC, OS, PFS and DFS was 86.7, 73.3, 82.7 and 68.0%, respectively; the 5-year LRC, OS, PFS and DFS were 54.7, 45.3, 44.0 and 56.7%, respectively. The differences were statistically significant (P<0.05). In the observation group, the number of leukocytes was decreased, and the incidence rates of acute oropharyngeal mucosa reaction and radiation dermatitis were significantly lower than those in the control group. The differences were statistically significant (P<0.05). In conclusion, IMRT combined with chemotherapy can improve the OS and the 3-year and 5-year LRC, PFS and DFS of elderly patients with locally advanced oropharyngeal cancer, reduce toxic and side effects, and improve patients' quality of life. PMID- 29467850 TI - Decrease of gamma-aminobutyric acid and zinc ions in the islet periportal circulation stimulates glucagon secretion during hypoglycemia. AB - The present study assessed the effects of gamma-aminobutyric acid (GABA) from beta-cells on glucose levels and glucagon secretion, and identified channels via which glucagon secretion is initiated. An in vivo experiment was performed containing three groups: Intrapancreatic artery infusion of GABA alone, GABA plus insulin or insulin alone in rats with diabetes. Rats infused with GABA and insulin were also subdivided in groups receiving additional infusion of K+ channel activator diazoxide (DIA), K+-channel blocker tolbutamide (TLB) and calcium channel blocker nifedipine (NIF). In the hypoglycemic state, termination of infusion of insulin and insulin plus GABA resulted in signaling to the alpha cells to secrete glycogen, while that of GABA alone did not. However, intrapancreatic artery infusion of K+-channel activator DIA, K+-channel blocker TLB or calcium channel blocker NIF in addition to GABA and insulin had no effect on glucagon secretion. In conclusion, if the delivery of insulin or GABA plus insulin in rats with hypoglycemia is terminated, beta-cells are stimulated and signal the alpha-cells to secrete glucagon. Thus, the detection of a sudden decrease in zinc levels by beta-cells as well as a decrease in GABA in the periportal circulation induces signaling to alpha-cells to stimulate them to secrete glucagon. PMID- 29467851 TI - Proteinase 3 expression on the neutrophils of patients with paroxysmal nocturnal hemoglobinuria. AB - Proteinase 3 (PR3) is released from neutrophils and regulates platelet activity, which is associated with cluster of differentiation (CD)177 antigen (NB1), a glycosylphosphatidylinositol-linked protein. In the present study, the effect of PR3 on thrombosis in paroxysmal nocturnal hemoglobinuria (PNH) and PNH-aplastic anemia (AA) syndrome was explored. The expression of PR3 and NB1 on CD59- neutrophils was detected by flow cytometry, immunofluorescence (IF), reverse transcription-quantitative polymerase chain reaction analysis and western blotting. Serum levels of PR3, proteinase-activated receptor 1 (PAR1) and D-Dimer were measured using ELISAs. The expression of PR3 and NB1 on the plasma membrane of CD59- neutrophils in patients with PNH/PNH-AA was significantly lower compared with their expression on CD59+ neutrophils in patients and controls (P=0.001). However, no correlation between PR3 and NB1 expression was identified. IF staining further demonstrated partially positive PR3 expression on CD59- neutrophils. The serum level of PR3 in patients was identified to be significantly decreased compared with healthy controls (P<0.0001), and significantly negatively correlated with PAR1 (r=-0.456; P=0.043) and D-Dimer (r= 0.503; P=0.028) levels. The mRNA and protein levels of PR3 on PNH clones did not change significantly compared with the control group. In conclusion, PR3 expression on the plasma membrane of neutrophils and in the serum of patients with PNH/PNH-AA decreased, which may result in increased PAR1 expression and increased clotting. The present study provides the basis for further study on platelets in PNH. PMID- 29467852 TI - In vitro and in vivo cytotoxic effect of AntiGan against tumor cells. AB - Novel effective chemopreventive agents against cancer are required to improve current therapeutic rates. The aim of the present study was to investigate the anti-carcinogenesis effect of AntiGan, an extract obtained from the European conger eel, Conger conger, in vitro (human tumor cell lines) and in vivo (murine model of colitis) models. The potential apoptogenic activity after 24 h of incubation with 10, 25 and 50 ul/ml AntiGan was reported using growth inhibition and apoptosis activity assays. In vivo studies were performed in mice by inducing colitis with oral administration of 2% dextran sulphate sodium (DSS) for 5 weeks. Apoptosis was observed in HL-60, Hs 313.T, SW-480, Caco-2 and HT-29 cell lines. The highest level of growth inhibition was observed in Caco-2 (66, 75.8 and 88.1%), HT-29 (56, 73 and 87.6%) and SW-480 (38.5, 61.6, 78.6%) for AntiGan doses of 10, 25 and 50 ul/ml, respectively, compared to untreated cells, while the results of the expression of genes associated with apoptosis indicated a downregulation of B-cell lymphoma 2 (Bcl-2) in all cell lines studied. In vivo, morphopathological alterations in the colon were analyzed by immunohistochemical and staining methods. Tumoral markers, including beta-catenin, cyclooxygenase 2 and Bcl-2 were expressed in cryptal cells of the dysplastic colonic mucosa, whereas the levels of interferon-gamma expression were also increased when no treatment was applied. In the experimental murine model, the optimal concentration of AntiGan for an effective dose-response was 10% in diet. These results suggested that AntiGan displays a powerful anti-inflammatory effect in DSS-induced colitis, acting as a chemopreventive agent against colon carcinogenesis, most likely due to its apoptogenic peptides that contribute to the induction of apoptosis. PMID- 29467853 TI - 640-slice DVCT multi-dimensionally and dynamically presents changes in bladder volume and urine flow rate. AB - The present study aimed to explore the application of 640-slice dynamic volume computed tomography (DVCT) to excretory cystography and urethrography. A total of 70 healthy subjects were included in the study. Excretory cystography and urethrography using 640-slice DVCT was conducted to continuously record the motions of the bladder and the proximal female and male urethra. The patients' voiding process was divided into early, early to middle, middle, middle to late, and late voiding phases. The subjects were analyzed using DVCT and conventional CT. The cross-sectional areas of various sections of the male and female urethra were evaluated, and the average urine flow rate was calculated. The 640-slice DVCT technique was used to dynamically observe the urine flow rate and changes in bladder volume at all voiding phases. The urine volume detected by 640-slice DVCT exhibited no significant difference compared with the actual volume, and no significant difference compared with that determined using conventional CT. Furthermore, no significant difference in the volume of the bladder at each phase of the voiding process was detected between 640-slice DVCT and conventional CT. The results indicate that 640-slice DVCT can accurately evaluate the status of the male posterior urethra and female urethra. In conclusion, 640-slice DVCT is able to multi-dimensionally and dynamically present changes in bladder volume and urine flow rate, and could obtain similar results to conventional CT in detecting urine volume, as well as the status of the male posterior urethra and female urethra. PMID- 29467854 TI - Cholecystokinin octapeptide inhibits the inflammatory response and improves neurological outcome in a porcine model of cardiopulmonary resuscitation. AB - Previous studies have demonstrated that cholecystokinin octapeptide (CCK8) induces hypothermia and inhibits the systemic inflammatory response in septic shock in rat and murine models. The present study aimed to ascertain whether CCK8 induced hypothermia and improved the neurological outcomes in a porcine model of cardiopulmonary resuscitation (CPR). Ventricular fibrillation was induced and left untreated for 10 min in 12 male Bama miniature pigs. Defibrillation was attempted after 5 min of CPR. At 5 min following resuscitation, the pigs were randomized and equally assigned into the CCK8 or the control group. CCK8 was continuously infused for 1 h at a dose of 44.4 ug/kg/h and a rate of 20 ml/h in the CCK8 group. Body temperature, hemodynamic measurements and post-resuscitation myocardial function were monitored in the first 4 h following CPR. Neuron specific enzyme (NSE), S100B protein, tumor necrosis factor (TNF)-alpha and interleukin (IL)-6 were measured at baseline and 4, 12 and 24 h following resuscitation. The neurological deficient score (NDS) was recorded and cerebral samples were collected for terminal deoxynucleotidyl-transferase-mediated dUTP nick end labelling assay and integrated optical density (IOD) analysis at 24 h following CPR. The results revealed that hypothermia was not induced by CCK8; however, post-resuscitation NSE, S100B, IL-6 and TNF-alpha were significantly decreased, and NDS and IOD were significantly improved in the CCK8 group compared with the control group (P<0.05). The present study revealed that in a porcine model of CPR, CCK8 does not induce hypothermia, but inhibits the inflammatory response and significantly improves neurological outcomes. PMID- 29467855 TI - Clinical characteristics and value in early reperfusion therapy for new onset right bundle branch block in patients with acute myocardial infarction. AB - The value of the right bundle branch block (RBBB) in the treatment of acute myocardial infarction remains unclear. Studies on the RBBB may significantly influence the treatment of acute myocardial infarction. A total of 845 patients with acute myocardial infarction who underwent primary coronary angiography at Henan Provincial People's Hospital were analyzed. Higher peak enzyme levels, a higher ratio of Killip >=II and closer proximal occlusion of infarct-related artery (IRA) were observed in patients with RBBB compared with those without. The ratio of TIMI flow 0/1 of IRA and ratio of received primary percutaneous coronary intervention (PCI) to IRA in the RBBB group were significantly higher compared with those in the left (L) BBB or no BBB groups. The in-hospital major adverse cardiac events (MACE) incidence in the RBBB group was higher compared with that in the no BBB group, but there was no significant difference between the RBBB and LBBB groups. Logistic regression revealed that proximal occlusion and TIMI flow 0/1 of IRA were predictive factors of RBBB. Cox regression analysis identified RBBB [risk ratio (RR), 4.682; P<0.001] and LBBB (RR, 3.687; P<0.001) as independent predictors of in-hospital MACE. The cumulative one-year survival rate in the RBBB group was significantly lower than those in the no BBB group (P<0.05) and the LBBB group (P<0.05). Similar to the guidelines regarding new onset of LBBB, new onset RBBB should be considered as a standard indicator for reperfusion therapy; as RBBB is associated with more severe symptoms, and higher incidents of complete occlusion of IRA and primary PCI treatment compared with LBBB. PMID- 29467856 TI - Smoking and female sex as key risk factors associated with severe arthralgia in acute and chronic phases of Chikungunya virus infection. AB - Arthralgia is a potentially incapacitating condition and a persistent symptom in chronic or acute episodes of Chikungunya fever caused by infection with the Chikungunya virus (CHIKV). To the best of our knowledge, there are no reports on risk factors associated with the intensity of arthralgias in typical acute episodes of the disease. Although a number of studies have reported on risk factors associated with the development of the chronic stage of the disease, smoking habits have not been analyzed. Smoking is an interesting factor to consider since it is the main environmental risk factor for the development of rheumatoid arthritis (RA), a similar disease to CHIKV in many aspects. In the present study, 140 patients infected with CHIKV were assessed for risk factors associated with severe arthralgia intensity in the acute phase (pain of 9/10 on the visual analog scale of 0-10) and moderate to severe intensity (according to the Routine Assessment of Patient Index Data 3) 3.5 months after infection in patients that experienced the chronic phase of the disease. Women and smokers were 2- to 3-times more likely to experience severe pain in the acute and chronic stages. Likewise, the presence of severe arthralgia during the acute disease phase resulted in a 4-fold increased risk for entering the chronic phase. Smoking was a more important risk factor in males compared with females. Smoking resulted in a 20-fold increased risk for severe arthralgia during the acute phase in men, as well as a 10-fold increased risk for developing chronic disease with moderate to-severe pain 3.5 months after the acute stage. The presence of rash, headache, muscular weakness or conjunctivitis in the acute phase, the presence of diabetes and age >40 years were considered significant risk factors due to their influence on illness progression. In conclusion, smoking and female sex were the main risk factors associated with development of severe joint pain in the acute and chronic phases of Chikungunya fever. These risk factors are similar to those associated with the development and severity of RA, possibly because the two diseases share pathophysiological mechanisms, including elevated interleukin-6 levels. PMID- 29467857 TI - Overexpression of microRNA-15 increases the chemosensitivity of colon cancer cells to 5-fluorouracil and oxaliplatin by inhibiting the nuclear factor-kappaB signalling pathway and inducing apoptosis. AB - Overcoming chemoresistance is a challenge in clinical treatment. It has been reported that microRNAs (miRNAs) are involved in regulating chemosensitivity. Therefore, the present study aimed to identify the effect and mechanism of miR-15 on colon cancer chemotherapy. Reverse transcription-quantitative polymerase chain reaction was performed to measure miR-15 level sin62-paired colon cancer and para cancerous colon tissues. The overexpression of miR-15 in HCT116 cells was induced by transfection. The effect of miR-15 on the chemosensitivity of colon cancer cells to 5-fluorouracil (5-FU) and Oxaliplatin (OX) was determined using a luminescent cell viability assay. Flow cytometry, dual-luciferase assay and western blot analysis were used to determine the potential mechanism of miR-15. The results suggested that the expression of miR-15 was decreased in tumour tissues and that overexpression of miR-15 increased the chemosensitivity of colon cancer cells to 5-Fu and OX. miR-15 promoted apoptosis in colon cancer cells treated with 5-Fu and OX by inhibiting the expression of p50, which repressed the expression of B cell lymphoma-2 and B cell lymphoma-extra large; two direct target genes of nuclear factor-kappaB with anti-apoptotic functions. Thus, the current study demonstrated that miR-15 increased the chemosensitivity of colon cancer cells to 5-FU and OX by inhibiting the NF-kappaB signalling pathway and inducing apoptosis. PMID- 29467858 TI - Effects of iodine-131 radiotherapy on Th17/Tc17 and Treg/Th17 cells of patients with differentiated thyroid carcinoma. AB - T helper 17 (Th17), T cytotoxic 17 (Tc17) and regulatory T (Treg) cells serve important roles in a number of inflammatory and autoimmune diseases. The aim of the present study was to examine the distribution of Th17, Tc17 and Treg cells in patients with differentiated thyroid cancer (DTC) prior to as well as 7, 30 and 90 days following radioactive iodine-131 (131I) therapy, and to elucidate the probable effects of 131I therapy on Th17/Tc17 and Treg/Th17 cells in patients with DTC. A total of 40 patients with DTC (26 female; 14 male) between the ages of 24 and 72 years, as well as 13 age- and sex-matched healthy subjects were included in this study. The number of Th17, Tc17 and Treg cells in the peripheral blood of patients with DTC and of healthy Controls were assessed by flow cytometry. Th17 and Tc17 cells were counted as percentages of the number of CD3+ T cells; Treg cells were counted as a percentage of the number of CD4+T cells. In addition, the serum levels of interleukin (IL)-17, IL-23, IL-10 and transforming growth factor (TGF)-beta1 were examined by ELISA. The frequencies of Th17, Tc17 and Treg cells, as well as the serum levels of IL-17, IL-23, IL-10 and TGF-beta1 were significantly elevated in patients with DTC compared with healthy Controls, whereas 131I therapy significantly decreased them. In addition, elevated Th17/Tc17 ratio and reduced Treg/Th17 ratio were observed in patients with DTC at day 0, however, these ratios returned to normal levels following 131I therapy for 90 days as compared with healthy Controls. Notably, Th17/Tc17 and Treg/Th17 ratios varied following 131I therapy for 7 and 30 days. In addition, a strong positive correlation between Th17 and Tc17 cells was observed in the healthy Controls and patients with DTC that received 131I treatment for 90 days, whereas a weak positive correlation between Th17 and Treg cell levels was identified in the healthy Controls and no obvious correlation between Th17 and Treg cells was observed in all patients with DTC pre- and post-131I therapy during the entire treatment period. These data suggested a significant involvement of Th17, Tc17 and Treg cells in the pathology of DTC. Restoring the balance of these cells may contribute to the recovery of patients with DTC following 131I therapy. PMID- 29467859 TI - Fisetin inhibits the growth and migration in the A549 human lung cancer cell line via the ERK1/2 pathway. AB - Lung cancer is the most prevalent malignant tumor type in the developed world and the discovery of novel anti-tumor drugs is a research hotspot. Fisetin, a naturally occurring flavonoid, has been reported to have anti-cancer effects in multiple tumor types. The present study found that fisetin inhibited the growth and migration of non-small cell lung cancer in vitro. MTT, wound-healing, cell matrix adhesion and Transwell assays were performed and demonstrated that fisetin suppressed proliferation, migration, adhesion and invasion, respectively. Flow cytometric analysis indicated that fisetin induced apoptosis in the A549 cell line by decreasing the expression of c-myc, cyclin-D1, cyclooxygenase-2, B cell lymphoma-2, CXC chemokine receptor type 4, cluster of differentiation 44 and metalloproteinase-2/9, increasing the expression of cyclin dependent kinase inhibitor (CDKN) 1A/B, CDKN2D and E-cadherin and increasing the activity of caspase-3/9 via targeting the extracellular signal-regulated kinase signaling pathway. The results provided comprehensive evidence for the anti-tumor effects of fisetin in non-small cell lung cancer in vitro, which may provide a novel approach for clinical treatment. PMID- 29467860 TI - Roles of microRNA-539 and osteopontin in rheumatoid arthritis. AB - The present study aimed to investigate the role and mechanism of microRNA-539 (miR-539) in rheumatoid arthritis (RA). A total of 68 RA patients and 46 osteoarthritis patients were enrolled into the current study. Peripheral blood and joint fluid were collected prior to treatment. Reverse transcription quantitative polymerase chain reaction was performed to detect osteopontin (OPN) mRNA and miR-539 expression levels, while ELISA and western blot analysis were applied to detect OPN protein expression. In addition, bioinformatics analysis predicted that miR-539 directly targeted OPN, while dual-luciferase assay was used to validate this finding. Furthermore, agomiR-539 transfection and OPN knockdown by siRNA were conducted in MH7A cells, and MTT assay was used to detect MH7A cell proliferation. The results indicated that OPN was significantly increased in the blood and joint fluid of RA patients, while miR-539 expression was significantly decreased in the two types of specimens (P<0.05). Subsequent to silencing OPN by siRNA, the proliferation of MH7A cells was decreased (P<0.05). Following upregulation of miR-539, OPN expression was significantly decreased and cell proliferation was inhibited. Dual-luciferase assay revealed that miR-539 regulated OPN expression through complementary binding to 3'-untranslated region. OPN was also significantly increased in the blood and joint fluid of RA patients, which may be associated with the downregulation of miR-539. Thus, miR-539 may promote the development and progression of RA through regulating OPN. PMID- 29467861 TI - Induction of apoptosis by an oleanolic acid derivative in SMMC-7721 human hepatocellular carcinoma cells is associated with mitochondrial dysfunction. AB - The aim of the present study was to investigate the effects of an oleanolic acid derivative, a novel antitumor drug, on the growth of SMMC-7721 human hepatocellular carcinoma cells and the underlying mechanism. An MTT assay was performed to determine the cytotoxicity of the oleanolic acid derivative. Cell membrane integrity was assessed using fluorescence microscopy to assess the uptake of annexin V-FITC/propidium iodide (PI). Western blotting was used to detect the apoptosis-associated proteins B cell lymphoma-2 (Bcl-2), Bax, caspase 9 and caspase-3. A spectrophotometer was used to analyze the intracellular adenosine triphosphate (ATP) expression level. The loss of mitochondrial membrane potential was detected by performing the JC-1 assay. ELISA was used to evaluate the content of cytochrome c (Cyt-C). The oleanolic acid derivative reduced the cell viability of SMMC-7721 cells in a dose- and time-dependent manner. The half maximal inhibitory concentration values of the oleanolic acid derivative in SMMC 7721 cells at 24, 48 and 72 h were 26.80, 11.85, and 6.66 uM, respectively. The antiapoptotic-protein Bcl-2 was downregulated, and the proapoptotic protein Bax was upregulated following treatment with the oleanolic acid derivative for 48 h. The oleanolic acid derivative induced the cleavage of caspase-9 and caspase-3 as well as promoted annexin V-FITC/PI uptake in SMMC-7721 cells. Furthermore, treatment of SMMC-7721 cells with the oleanolic acid derivative induced a reduction of the intracellular ATP expression level, loss of DeltaPsim and Cyt-C release from the mitochondria. The oleanolic acid derivative induced apoptosis in SMMC-7721 human cells. Mitochondrial dysfunction was involved in the anticancer effects of this derivative on SMMC-7721 human cells. PMID- 29467862 TI - Lentivirus-mediated silencing of HOTAIR lncRNA restores gefitinib sensitivity by activating Bax/Caspase-3 and suppressing TGF-alpha/EGFR signaling in lung adenocarcinoma. AB - Secondary resistance is a major limitation in the efficacy of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor treatment of lung cancer. Previous studies have shown that expression of the long non-coding RNA HOX transcript antisense RNA (HOTAIR) is upregulated in lung cancer, which is correlated with metastasis and poor prognosis. However, the precise role of HOTAIR and its effects on gefitinib resistance in human lung adenocarcinoma are not known. To address this issue, in the present study we established a gefitinib resistant (R)PC-9 human lung adenocarcinoma cell line and examined cell viability with the 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4 sulfophenyl)-2H-tetrazolium assay. We found that gefitinib concentrations <10 uM inhibited the viability of PC-9 but not RPC-9 cells in a dose-dependent manner. Lentivirus-mediated HOTAIR RNA interference induced cell apoptosis and S-phase arrest, as determined by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling and flow cytometry. Consistent with these observations, HOTAIR suppression was associated with tumor shrinkage and restoration of gefitinib sensitivity in RPC-9 xenograft mice. Immunohistochemical analyses and western blot revealed that HOTAIR silencing resulted in the upregulation of B cell lymphoma 2-associated X protein (Bax), Caspase-3 and transforming growth factor alpha (TGF-alpha) and downregulation of EGFR and B cell lymphoma 2 (Bcl-2) levels. These results indicate that HOTAIR normally prevents the activation of Bax/Caspase-3 while inducing TGF-alpha/EGFR signaling. Thus, targeting HOTAIR may be a novel therapeutic strategy for treating gefitinib-resistant lung adenocarcinoma. PMID- 29467863 TI - Detection of EGFR and BRAF mutations by competitive allele-specific TaqMan polymerase chain reaction in lung adenocarcinoma. AB - Epithelial growth factor receptor (EGFR)-tyrosine kinase inhibitors are the standard first-line treatment for patients with metastatic non-small cell lung cancer (NSCLC) expressing sensitive EGFR-mutants. Other drugs target different driver mutants, including the serine/threonine-protein kinase B-raf (BRAF) inhibitor dabrafenib, which has exhibited promising efficacy for treating patients with metastatic BRAF-mutated NSCLC. Therefore, identifying patients carrying mutations that may be treated using targeted therapies is important. However, the methods of molecular detection presently applied in clinical practice, particularly detection of BRAF in NSCLC patients, require further investigation. Therefore, more sensitive and economic methods are required. The present study applied the competitive allele-specific TaqMan polymerase chain reaction (CastPCR) technology to the molecular detection of EGFR (del2235-2249, del2236-2250, T790M, L858R) and BRAF (V600E, G469A, D594G) mutations in 144 treatment-naive patients with lung adenocarcinoma, and analyzed the association between the mutation rates and patients' clinicopathological features. 51.4% (74/144) cases were identified harboring EGFR mutations. A total of 40.3% (58/144) patients carried sensitizing mutations (exon 19 deletion or L858R) and 14.6% (21/144) carried T790M mutations. 6.9% (10/144) mutation-positive patients were double-mutated. Total EGFR mutation rate was significantly increased in female compared with that of males (60.9 vs. 43.8%, P<0.05), in non-smokers compared with that of smokers (62.8 vs. 34.5%, P<0.05). In total, 8.3% (12/144) patients were identified with BRAF mutations. 16.7% were V600E (2/12) and 83.3% (10/12) were non-V600E mutants. Among the 10 non-V600E mutations, D594G accounted for 90.0% (9/10) and G469A accounted for 10.0% (1/10). Statistical analysis demonstrated that the BRAF mutation rate was not associated with any of the following clinicopathological features: Sex, age, smoking history, clinical stages, distant metastasis, differentiation degree, tumor size and regional lymph node metastasis (P>=0.05). CastPCR technology is a robust method with high sensitivity for the molecular detection of EGFR and BRAF mutations in clinical formalin-fixed paraffin-embedded samples.

AB - Due to the high mortality rate and unsatisfactory treatment options available, hepatocellular carcinoma (HCC) remains one of the most common malignancies and a leading cause of cancer-associated mortality. Novel therapeutic targets for HCC are urgently required. Advanced RNA sequencing technology enables the identification of considerable amounts of noncoding RNAs (ncRNAs), including small noncoding RNAs and long noncoding RNAs, which exhibit no protein-coding activities. In this respect, ncRNAs and their regulatory processes are important factors in liver tumorigenesis. The present review focuses on the characteristics and biological roles of ncRNAs in HCC. Potential therapeutic applications of ncRNAs in HCC are also evaluated. PMID- 29467865 TI - Discoidin domain receptor 1: New star in cancer-targeted therapy and its complex role in breast carcinoma. AB - Discoidin domain receptor 1 (DDR1) is a receptor tyrosine kinase activated by various types of collagens that performs a critical role in cell attachment, migration, survival and proliferation. The functions of DDR1 in various types of tumor have been studied extensively. However, in breast carcinoma, the roles of collagen-evoked DDR1 remain ill defined. Although a number of studies have reported that DDR1 promotes apoptosis and inhibits migration in breast carcinoma, it has also been reported to be associated with tumor cell survival, chemoresistance to genotoxic drugs and the facilitation of invasion. The present review summarizes current progress and the complex effects of DDR1 in the field of breast carcinoma, and presents DDR1 as a promising therapeutic target. PMID- 29467866 TI - Notch signaling and non-small cell lung cancer. AB - Lung cancer is the leading cause of cancer-associated mortality worldwide. Elucidation of the pathogenesis and biology of lung cancer is critical for the design of an effective treatment for patients. Non-small cell lung cancer (NSCLC) accounts for 80-85% of lung cancer cases. The abnormal expression of Notch signaling pathway members is a relatively frequent event in NSCLC. The Notch signaling pathway serves important roles in cell fate determination, proliferation, differentiation and apoptosis. Increasing evidence supports the association of Notch signaling dysregulation with various types of malignant tumor, including NSCLC. Several studies have demonstrated that members of the Notch signaling pathway may be potential biomarkers for predicting the progression and prognosis of patients with NSCLC. Furthermore, Notch signaling serves critical roles in the tumorigenesis and treatment resistance of NSCLC cells by promoting the proliferation or inhibiting the apoptosis of NSCLC cells. The present review provides a detailed summary of the roles of Notch signaling in NSCLC. PMID- 29467867 TI - Low-molecular-weight polysaccharides from Agaricus blazei Murrill modulate the Th1 response in cancer immunity. AB - To assess the effect of low-molecular-weight polysaccharides from Agaricus blazei Murrill (ABP-AW1) as an immunoadjuvant therapy for type 1 T-helper (Th1) responses in tumorigenesis, C57BL/6 mice were inoculated subcutaneously with ovalbumin (E.G7-OVA). After 3, 10 and 17 days, the mice were immunized with PBS, OVA alone, or OVA and ABP-AW1, at low (50 ug), intermediate (100 ug) or high (200 ug) doses. Tumor growth was examined and compared among the groups, as were the following parameters: Splenocyte viability/proliferation, peripheral blood CD4+/CD8+ T cell ratio, serum OVA-specific IgG1 and IgG2b, secretion of interleukin (IL)-2 and interferon (IFN)-gamma, and IFN-gamma production on a single cell level from cultured splenocytes. Tumor growth in mice treated with OVA and ABP-AW1 (100 or 200 ug) was significantly slower, compared with in the other groups at the same time-points. OVA with 100 or 200 ug ABP-AW1 was associated with a higher number of total splenocytes, a higher ratio of peripheral blood CD4+/CD8+ T-lymphocytes, higher serum levels of OVA-specific Th1 type antibody IgG2b and greater secretion of the Th1 cytokines IL-1 and IFN-gamma from splenocytes. ABP-AW1 is a promising immunoadjuvant therapy candidate, due to its ability to boost the Th1 immune response when co-administered with a cancer vaccine intended to inhibit cancer progression. PMID- 29467868 TI - Angiogenesis for tumor vascular normalization of Endostar on hepatoma 22 tumor bearing mice is involved in the immune response. AB - Tumor vascular normalization involved in immune response is beneficial to the chemotherapy of tumors. Recombinant human endostatin (Endostar), an angiogenesis inhibitor, has been demonstrated to be effective in hepatocellular cancer (HCC). However, its vascular normalization in HCC and the role of the immune response in angiogenesis were unclear. In the present study, effects of Endostar on tumor vascular normalization were evaluated in hepatoma 22 (H22) tumor-bearing mice. Endostar was able to inhibit the proliferation and infiltration of tumor cells and improve alpha-fetoprotein, tumor necrosis factor-alpha and cyclic adenosine 5'-phosphate levels in the serum of H22-bearing mice, as well as the protein expression levels of the immune factors interferon-gamma and cluster of differentiation (CD)86 in liver tissue. Endostar also exhibited more marked downregulation of the levels of vascular endothelial growth factor, CD31, matrix metalloproteinase (MMP)-2, MMP-9 and interleukin-17 during day 3-9 treatment, resulting in short-term normalization of tumor blood vessels. The period of vascular normalization was 3-9 days. The results of the present study demonstrated that Endostar was able to induce the period of vascular normalization, contributing to a more efficacious means of HCC treatment combined with other chemotherapy, and this effect was associated with the immune response. It may be concluded that Endostar inhibited immunity-associated angiogenesis behaviors of vascular endothelial cells in response to HCC. The results of the present study provided more reasonable possibility for the combination therapy of Endostar for the treatment of HCC. PMID- 29467869 TI - Role of epithelial-mesenchymal transition markers E-cadherin, N-cadherin, beta catenin and ZEB2 in laryngeal squamous cell carcinoma. AB - Epithelial-mesenchymal transition (EMT) allows neoplastic cells to gain the invasive phenotype and become migratory, which is required for cancer progression and metastasis. In the present study, the expression of EMT-associated biomarkers and their association with clinicopathological parameters in laryngeal squamous cell carcinoma (LSCC) was investigated. E-cadherin, N-cadherin, beta-catenin and zinc finger E-box binding homeobox 2 (ZEB2) protein expression was evaluated with immunohistochemistry in a cohort of 76 patients with operable LSCC. The association between these transition markers, clinicopathological parameters and their prognostic impact in LSCC was analyzed. Immunohistochemical analysis revealed that EMT-associated proteins were differentially expressed between LSCC and adjacent non-neoplastic laryngeal tissue. Negative E-cadherin expression and positive N-cadherin, beta-catenin and ZEB2 expression were associated with a later tumor (T) stage, decreasing tumor differentiation and a reduced overall survival (OS) time (OS: E-cadherin, P=0.016; N-cadherin, P=0.003; beta-catenin, P=0.002; ZEB2, P=0.0003). E-cadherin/beta-catenin co-expression was significantly associated with the majority of clinicopathological parameters assessed, including lymph node metastases, T stage and tumor cell differentiation (P=0.004, P=0.005, and P<0.001, respectively). Multivariate analysis indicated that T stage and the positive expression of beta-catenin and ZEB2 were independent risk factors for OS in LSCC (P=0.014, P=0.025 and P=0.003, respectively). It was concluded that EMT mediates tumor progression, and reduces OS time in patients with LSCC. E-cadherin/beta-catenin co-expression may be associated with clinicopathological parameters. T stage, and the positive co-expression of beta catenin and ZEB2 may be independent predictors of prognosis in LSCC. PMID- 29467870 TI - HIF-1alpha promotes ZEB1 expression and EMT in a human bladder cancer lung metastasis animal model. AB - Lung is one of the most common sites for bladder cancer to metastasize. Although the involvement of the epithelial-to-mesenchymal transition (EMT) in bladder cancer progression has been established, the mechanism of EMT induction remains unclear. In order to investigate this, T24-parental (P) and T24-lung (L) bladder cancer cells were obtained from primary tumors and lung metastatic sites of an animal model with orthotopic spontaneous metastatic bladder cancer, according to a protocol previously described. Compared with T24-P cells, mesenchymal-like T24 L cells exhibited an increased ability in tumor invasion and metastasis, as well as an increased expression of hypoxia-inducible factor (HIF)-1alpha, zinc finger E-box-binding homeobox 1 (ZEB1), vimentin and N-cadherin and lower level of cytokeratin 18 were observed. Mechanistically, it was identified that HIF-1alpha increases ZEB1 expression and subsequently regulates the expression of EMT related genes in both HIF-1alpha knocking down by siRNA and gain-in HIF-1alpha by hypoxia culture cell models. In addition, the expression of HIF-1alpha and ZEB1 in bladder cancer tissues were increased compared with normal bladder epithelial tissues, as well as significantly increased in the high-grade, invasive and metastatic bladder cancer tissues compared with low-grade, superficial and non metastatic bladder cancer tissues by using immune-histochemical staining assay. Notably, the protein level of HIF-1alpha was positively associated with that of ZEB1 in bladder cancer tissues. Results from the present study indicate that HIF 1alpha promotes ZEB1 expression and EMT in the T24-L human bladder cancer lung metastasis animal model, suggesting that HIF-1alpha serves an important function in the metastasis of bladder cancer, and HIF-1alpha and ZEB1 may be potential targets for inhibiting bladder metastasis in the future. PMID- 29467871 TI - Abnormal expression of circulating and tumor-infiltrating carcinoembryonic antigen-related cell adhesion molecule 1 in patients with glioma. AB - Glioma, the most prevalent primary tumor of the central nervous system, is known to evade immune surveillance and escape immune attacks by inducing immunosuppression. The homophilic interactions of the carcinoembryonic antigen related cell adhesion molecule 1 (CEACAM1) serve a critical function in immunoregulation. In the present study, the expression levels of CEACAM1 in peripheral blood mononuclear cells and tumor-infiltrating lymphocytes (TILs) from patients with gliomas were assessed. Furthermore, associations between CEACAM1 expression and multiple clinicopathological characteristics in patients with gliomas were analyzed. The results of the present study suggested that the expression of CEACAM1 in circulating T cells was markedly increased in patients with gliomas compared with control subjects, and was further increased in TILs. Patients with high-grade gliomas [World Health Organization (WHO) grade III-IV] demonstrated a significantly increased expression of CEACAM1 on T cells compared with those with low-grade gliomas (WHO grade I-II). Furthermore, the expression of CEACAM1 on T cells was negatively correlated with the Karnofsky score and the plasma level of interferon-gamma in patients with gliomas. Immunohistochemical analysis revealed that the expression levels of CEACAM1 in high-grade glioma tissues (WHO grade III-IV) were increased compared with the expression levels in the controls, and were associated with the expression of CEACAM1 in TILs. In summary, the results of the present study indicate that homophilic interactions of CEACAM1 may participate in the progression and development of gliomas through their negative regulatory effects on T cells. Thus, CEACAM1 may be a promising candidate for targeted glioma immunotherapy. PMID- 29467872 TI - Differential microRNA expression profiles in tamoxifen-resistant human breast cancer cell lines induced by two methods. AB - Tamoxifen (TAM) resistance has become a severe problem for endocrine therapy of breast cancer. The present study investigated the association between microRNA (miRNA) expression and TAM resistance in breast cancer. The TAM-resistant breast cancer MCF-7C and MCF-7T cell lines were established using the human breast cancer cell line MCF-7 as the parental cell line and 4-hydroxytamoxifen (OHT) as the screening drug in vitro. The MCF-7C cell line was established by dose stepwise induction beginning with a low concentration of OHT; the MCF-7T cell line was established by temporal stepwise induction beginning with a high concentration of OHT. Differential miRNA expression profiles between TAM sensitive (MCF-7) and TAM-resistant (MCF-7C and MCF-7T) breast cancer cell lines were detected and analyzed using RNA sequencing technology. The results of western blot analysis indicated that the level of ERalpha protein expression in drug-resistant cells was significantly increased. A total of 1,646 miRNAs were detected in all samples, including 1,376 known miRNAs and 270 predicted miRNAs. There were 118 miRNAs expressed at significantly different levels between MCF-7C and MCF-7 cells (P<0.05); among them, 67 miRNAs were upregulated (P<0.05) and 51 miRNA were downregulated (P<0.05). There were 42 miRNAs expressed at significantly different levels between MCF-7T and MCF-7 (P<0.05); among them, 23 miRNAs were upregulated (P<0.05) and 19 miRNAs were downregulated (P<0.05). There were 126 miRNAs with significant differences between MCF-7C and MCF-7T (P<0.05); among them, 76 miRNAs were upregulated (P<0.05) and 50 miRNAs were downregulated. On the basis of the results of the present study, we hypothesize that miR-21, miR 146a, miR-148a, miR-34a and miR-27a may serve important roles in mediating TAM resistance in breast cancer, and have potential as therapeutic targets for TAM resistant breast cancer. PMID- 29467873 TI - Utility of Survivin, BAP1, and Ki-67 immunohistochemistry in distinguishing epithelioid mesothelioma from reactive mesothelial hyperplasia. AB - Histological distinction between epithelioid mesothelioma (EM) and reactive mesothelial hyperplasia (RMH) can be challenging. The aim of this study was to assess the diagnostic utility of Survivin, Ki-67, and loss of BRCA1-associated protein 1 (BAP1) expressions in distinguishing EM from RMH using immunohistochemistry. Formalin-fixed, paraffin-embedded specimens from 78 cases of EM and 80 cases of RMH were immunohistochemically examined for Survivin, BAP1, and Ki-67. In addition, receiver operating characteristic curve analyses were performed to establish the cut-off values for Survivin and Ki-67 labelling indices. Survivin (cut-off value: 5%) had 67.7% sensitivity and 100% specificity, while Ki-67 (cut-off value: 10%) had 85.1% sensitivity and 87.5% specificity, and BAP1 had 66.2% sensitivity and 100% specificity for the differentiation of EM from RMH. Among the combinations of two markers, the combination of Survivin and BAP1 (Survivin-positive and/or BAP1-loss finding) had the highest diagnostic accuracy (sensitivity: 89.8%; specificity: 100%; accuracy: 95.3%). We recommend using the combination of Survivin and BAP1 to distinguish EM from RMH. PMID- 29467874 TI - Effects of NOB1 on the pathogenesis of osteosarcoma and its expression on the chemosensitivity to cisplatin. AB - The effects of NIN1/RPN12 binding protein 1 homolog (NOB1) on the pathogenesis of osteosarcoma and its expression on the chemosensitivity to cisplatin were investigated. Seventy-four patients with osteosarcoma who received surgical resection in The Affiliated Hospital of Southwest Medical University (Sichuan, China) from September 2013 to September 2016 were enrolled in this study. The expression of NOB1 in cancer and cancer-adjacent tissues of patients was detected by reverse transcription-polymerase chain reaction, and the relationship between NOB1 expression and the pathogenesis of osteosarcoma was analyzed. The expression of NOB1 in osteosarcoma MG-63 cells was interfered with using small interfering ribonucleic acid (siRNA). Western blotting was used to detect the transfection efficiency and changes in apoptosis indicators. Cell Counting Kit-8 (CCK-8) assay was used to examine changes in the sensitivity of cells to cisplatin. The effect of NOB1 knockout on cell apoptosis was examined by flow cytometry. In patients with osteosarcoma, the level of NOB1 mRNA in cancer tissues was significantly higher than that in cancer-adjacent tissues (p<0.05), and the expression of NOB1 was correlated with Ennecking staging and tumor size (p<0.05). The expression level of the apoptotic indicator caspase-3 was activated after siRNA interfered with NOB1 expression, thus reducing the expression level of anti-apoptotic indicator B-cell lymphoma 2. CCK-8 results showed that the downregulation of NOB1 increased the sensitivity of MG-63 cells to cisplatin (p<0.05). In addition, flow cytometry showed that the downregulation of NOB1 significantly promoted the apoptosis of MG-63 cells. NOB1 is significantly upregulated in patients with osteosarcoma, thus reducing the curative effect of cisplatin chemotherapy, which indicates that the prognosis is poor. PMID- 29467875 TI - Potential prognostic biomarkers identified by DNA methylation profiling analysis for patients with lung adenocarcinoma. AB - Lung adenocarcinoma is frequently occurring type of lung cancer with high metastatic risk. We performed a DNA methylation profiling analysis to identify possible prognostic markers involved in lung adenocarcinoma. DNA methylation profiling data (GSE66386) were downloaded from the Gene Expression Omnibus (GEO) database. Differentially methylated genes were identified using a limma package. GO enrichment analysis was performed to identify vital functions related to differential gene methylation, and pathway analysis was performed to assess the associations between different proteins with regard to regulation of cell function and metabolism. The screening results showed a total of 112,662 differentially methylated genes in lung adenocarcinoma patients compared with those of the normal controls. These CpGs were involved in 16,705 genes. The skeletal system development (P=9.46E-27) and embryonic organ morphogenesis (P=8.67E-24) were found to be involved in lung adenocarcinoma. The cancer (P=3.64E-07), Rap1 signaling (P=9.21E-05) and calcium signaling (P=9.21E-05) pathways constituted the important pathways associated with lung adenocarcinoma. In conclusion, methylated PTPRF, HOXD3, HOXD13 and CACNA1A are potential markers and may be utilized for the diagnosis and therapy of lung adenocarcinoma. PMID- 29467876 TI - Comparison of the safety of the application of painless gastroscopy and ordinary gastroscopy in chronic hypertension patients combined with early gastric cancer. AB - The aim of the present study was to compare the safety of the application of painless gastroscopy and ordinary gastroscopy for chronic hypertension patients combined with early gastric cancer. A total of 123 patients with early gastric cancer were selected at the Dongying People's Hospital from June, 2014 to August, 2016. The patients were randomly divided into the painless (n=63) and ordinary (n=60) gastroscopy groups. Proper pretreatment was performed according to whether anesthesia was performed or not. Arterial pressure, heart rate, and blood oxygen saturation were detected and compared before anesthesia, when gastroscope passed through the esophageal entrance plane, and after recovery from anesthesia. The incidence of nausea and vomiting, cough, dysphoria, throat discomfort and other adverse reactions during and after surgery were recorded and compared. Compared with the levels before anesthesia, the mean arterial pressure, heart rate and blood oxygen saturation were significantly reduced in painless gastroscopy when the gastroscope passed through the esophageal entrance plane (P<0.05). In the ordinary gastroscopy group, the mean arterial pressure, heart rate and blood oxygen saturation were significantly increased when the gastroscope passed through the esophageal entrance plane compared with the levels before anesthesia (P<0.05). Blood pressure decreased in the painless gastroscopy group whereas it increased in the ordinary gastroscopy group after anesthesia. The decrease in the painless gastroscopy group was lower than in the ordinary group. The incidence of intraoperative and postoperative adverse reactions including nausea, vomiting, cough, dysphoria, pharyngeal discomfort and other adverse reactions was significantly decreased in the painless gastroscopy group than in the ordinary gastroscopy group (P<0.05). The results suggest that the application of painless gastroscopy in chronic hypertension patients can significantly reduce the incidence of intraoperative and postoperative adverse reactions compared with that of the Gastric cancer ordinary gastroscopy. Thus, painless gastroscopy is safer than ordinary gastroscopy. PMID- 29467877 TI - Rapid detection of quantum dot immune chromatography nasopharyngeal carcinoma EBNA1 antibody. AB - This study explored the 605 nm carboxyl of water-soluble quantum dots to assess the practicability of the nasopharyngeal carcinoma marker EBNA1 antibody. We used 605 nm carboxyl water-soluble quantum dots and nasopharyngeal carcinoma EBNA1 antigen in 1-(3-dimethylaminopropyl-3-2-ethylcarbonimine hydrochloride to generate quantum dot-labeled antigen. Gel imaging system showed that serum group and 60 patients with nasopharyngeal carcinoma had significant differences in 30 cases of normal adult serogroup brightness, Levene test in the two groups ELISA absorbance value was P<0.001, namely the nasopharyngeal carcinoma group and the normal adult serum group measured absorbance value difference was obvious. The statistical significance, and the detection technology were of high specificity and sensitivity. In conclusion, this study adopted double antigen clip combining immune chromatography test EBNA1 antibody in serum, compared with the traditional enzyme-linked immunoassays this method is more rapid, with simpler operation, rapid detection for developing quantum dot immune chromatography technology the EBNA1 antibody kit provides a theoretical basis. PMID- 29467878 TI - Parthenolide facilitates apoptosis and reverses drug-resistance of human gastric carcinoma cells by inhibiting the STAT3 signaling pathway. AB - In the present study, SGC-7901/DDP cells were treated with different concentrations of parthenolide (PN) (2.5-15 umol/l), cisplatin (DDP) (1.25-15 ug/ml) and PN+DDP. The proliferation inhibition rates were measured using an MTT assay, and the synergies of PN and DDP were analyzed. The effect of PN and DDP on SGC-7901/DDP cell proliferation demonstrated a time- and concentration-dependent association, and a synergy between PN and DDP was identified. DAPI staining and flow cytometry results indicated that 15 umol/l PN significantly induced SGC 7901/DDP apoptosis and G1 phase arrest compared with the untreated control group. Western blotting analysis results indicated that among the apoptosis-associated proteins, there were dose-dependent increases in the protein expression of apoptosis regulator BAX, cellular tumor antigen p53, cleaved caspase-3 and cleaved capase-9, and decreases in apoptosis regulator Bcl-2 and Bcl-xL protein expression levels. Among the cell cycle-associated proteins, cyclin D1 expression was significantly decreased, cyclin-dependent kinase inhibitor 1 expression was significantly increased, and signal transducer and activator of transcription 3 (STAT3) activation was inhibited. Scratch and Transwell assay results revealed that PN significantly inhibited SGC-7901/DDP cell migration, and invasion. The present study demonstrated that PN induces SGC-7901/DDP apoptosis, inhibits SGC 7901/DDP proliferation, migration and invasion, and enhances the drug sensitivity of the cells to DDP. The underlying mechanisms may be associated with inhibition of the STAT3 signaling pathway and regulation of the downstream apoptotic protein and cyclin expression levels. PMID- 29467879 TI - Loss of CDX2 gene expression is associated with DNA repair proteins and is a crucial member of the Wnt signaling pathway in liver metastasis of colorectal cancer. AB - Caudal type homeobox 2 (CDX2) has been well-established as a diagnostic marker for colorectal cancer (CRC); however, less is known about its regulation, particularly its potential interactions with the DNA repair proteins, adenomatous polyposis coli (APC) and beta-catenin, in a non-transcriptional manner. In the present study, the protein expression of CDX2 was analyzed, depending on the expression of the DNA repair proteins, mismatch repair (MMR), O6-methylguanine DNA methyltransferase (MGMT) and excision repair cross-complementing 1 (ERCC1), and its importance in Wnt signaling was also determined. A total of 101 liver metastases were punched into tissue microarray (TMA) blocks and serial sections were cut for immunohistochemistry. For each protein, an immunoreactive score was generated according to literature data and the scores were fitted to TMA. Subsequently, statistical analysis was performed to compare the levels of expression with each other and with clinical data. CDX2 loss of expression was observed in 38.5% of the CRC liver metastasis cases. A statistically significant association between CDX2 and each of the investigated MMRs was observed: MutL Homolog 1 (P<0.01), MutS protein Homolog (MSH) 2 (P<0.01), MSH6 (P<0.01), and postmeiotic segregation increased 2 (P=0.040). Furthermore, loss of MGMT and ERCC1 was also associated with CDX2 loss (P=0.039 and P<0.01, respectively). In addition, CDX2 and ERCC1 were inversely associated with metastatic tumor size (P=0.038 and P=0.027, respectively). Sustained CDX2 expression was associated with a higher expression of cytoplasmic/membranous beta-catenin and with nuclear APC expression (P=0.042 and P<0.01, respectively). In conclusion, CDX2 loss of expression was not a rare event in liver metastasis of CRC and the results suggested that CDX2 may be involved in mechanisms resulting in the loss of DNA repair protein expression, and in turn methylation; however, its exact function in this context remains to be elucidated. PMID- 29467880 TI - The role of immune cell subpopulations in the growth and rejection of TC-1/A9 tumors in novel mouse strains differing in the H2-D haplotype and NKC domain. AB - The present study aimed to elucidate the role of cluster of differentiation (CD)8+, CD4+, natural killer (NK), and myeloid (CD11b+) cells in the course of the growth and rejection of experimental major histocompatibility complex (MHC) class I-deficient, HPV16 E6/E7-associated TC-1/A9 tumors in mice. Stable mouse lines (F30) generated by inbreeding of Balb/c and C57BL/6 strains, which were characterized by H-2Db+d-NK1.1neg (B6-neg) and H-2Db-d+NK1.1high (Balb-high) phenotypes, were used for the present study. The novel strains spontaneously regressed tumors in 70-90% of cases. Ex vivo histological analysis of the tumor microenvironment in cryosections showed an indirect correlation between the growth of the transplanted tumor (progressor vs. regressor mice) and the proportion of immunocompetent cell infiltration in the tumors. The regressor mice exhibited a higher infiltration of tumors with CD4+ and CD8+ cells, and in Balb high with NK cells as well, compared with the progressors. All tumor transplants also indicated a huge infiltration of CD11b+ cells, but this infiltration was not dependent on the stage of the TC-1/A9 tumor development. Depletion of individual cell subpopulations in vivo exhibited different effects on the tumor development in the two strains. Elimination of CD8-positive cells enhanced growth of TC-1/A9 tumor transplants in both hybrid stains, whereas CD4+ cell depletion affected rejection of TC-1/A9 tumors in the B6-neg mice only. Depletion of NK cells with anti-asialo GM1 antibody in the Balb-high strain led to enhancement of tumor growth, which was more pronounced after depletion of the NK1.1+ subpopulation. On the other hand, depletion of NK cells with anti-asialo GM1 in B6-neg mice did not affect the regression of TC-1/A9 tumor transplants, but increased the CD11b+ cell infiltration. In summary, these results indicate that co-operation of particular subsets of immunocompetent cells is essential for the rejection of TC-1/A9 tumor transplants. In B6-neg mice, the co-operative action of CD8+ and CD4+ cells is required, whereas in Balb-high mice, the synergy of CD8+ and NK1.1+ cells is of major importance. PMID- 29467881 TI - Diffuse large B-cell lymphoma: 10 years' real-world clinical experience with rituximab plus cyclophosphamide, doxorubicin, vincristine and prednisolone. AB - Treatment with rituximab plus a regimen of cyclophosphamide, doxorubicin, vincristine and prednisolone (CHOP) for patients with diffuse large B-cell lymphoma (DLBCL) has proven efficacy in clinical trials. The present study investigated its application in clinical practice. This single-center, retrospective database analysis included patients with DLBCL treated at the Slovenian Institute of Oncology Ljubljana between 2004 and 2013. Overall survival (OS) and progression-free survival (PFS) were assessed according to International Prognostic Index (IPI) and revised IPI (R-IPI) categories. Overall, 573 patients with DLBCL were included in the study (median follow-up, 45.3 months; range, 0.1 143.0). Patients were categorized as IPI 'low' (n=170; 30%), 'low-intermediate' (n=134; 23%), 'high-intermediate' (n=129; 23%) and 'high' (n=140; 24%) risk. R IPI groups were indicated with 'very good' (n=59; 10%), 'good' (n=245; 43%) and 'poor' (n=269; 47%) prognosis. Ten-year OS and PFS rates were 51 and 72%, respectively; median OS was 124 months and median PFS was not reached. Ten-year OS rates were 80 and 87% in low-risk and 'very good' prognosis groups, respectively, and 30 and 37% in high-risk and poor prognosis patients, respectively. This analysis of patients with DLBCL indicated that many patients treated with R-CHOP and R-CHOP-like regimens in the real-world setting have excellent outcomes. PMID- 29467882 TI - Primary pulmonary intravascular large B-cell lymphoma: A report of three cases and literature review. AB - The present study aimed to investigate the clinicopathological features of primary intravascular large B-cell lymphoma (IVLBCL) of the lung. The clinical and histopathological data of three patients, and the literature was reviewed. The Ethics Committees of Drum Tower Hospital approved the current study based on the three cases. Fever and respiratory symptoms were the main presenting symptoms. Serum lactate dehydrogenase and C-reactive protein were significantly increased. Diffuse ground glass opacities or nodular consolidations were seen on high resolution computed tomography. Lung biopsy revealed lymphoma cells in the lumen of small blood vessels. Tumor cells expressed cluster of differentiation 20 and melanoma associated antigen (mutated) 1. Primary pulmonary IVLBCL is extremely rare and its prognosis is poor. Full recognition of its clinical character and improvement of the diagnostic awareness may help to reduce missed diagnosis, and facilitate appropriate treatment. PMID- 29467883 TI - Effects of Yangzheng Sanjie Decoction-containing serum mediated by microRNA-7 on cell proliferation and apoptosis in gastric cancer. AB - Gastric cancer (GC) is one of the most common types of cancer and a leading cause of cancer-associated mortality. MicroRNAs (miRNAs/miRs) are demonstrated to function as oncomiRs or tumor-suppressor-miRs in GC. miR-7 has been identified to be a tumor suppressor of GC by targeting epidermal growth factor receptor (EGFR). In our previous study, Yangzheng Sanjie Decoction (YZSJD), a traditional Chinese formula, was identified to be effective in alleviating the symptoms and even postponing turnover of precancerous lesions. To elucidate the mechanism of YZSJD, the present study evaluated the effects of YZSJD of the GC MKN-45 cell line and investigated the underlying molecular mechanisms using YZSJD-containing serum (YCS). The expression of miR-7 in GC, normal and adjacent tissue samples was examined. The results demonstrated that YCS inhibited proliferation by inducing cell cycle arrest at the S phase, and significantly induced apoptosis compared with the control group. miR-7 was significantly downregulated in GC tissues compared with the matched ones. Using reverse transcription-quantitative polymerase chain reaction and western blot analysis, the expression of miR-7 was inversely associated with EGFR. This indicates that YCS inhibits proliferation and induces apoptosis of GC cells mediated by miR-7 targeting EGFR, which may be one of the mechanisms whereby YZSJD exerts its effects on GC. PMID- 29467884 TI - Etaypoxia-inducible factor 1-alpha promotes colon cell proliferation and migration by upregulating AMPK-related protein kinase 5 under hypoxic conditions. AB - Hypoxia is a common characteristic of solid tumors. Previous studies have reported that the tumor invasion-associated factor, AMPK-related protein kinase 5 (ARK5), is associated with a poor prognosis in colon cancer. However, whether or not ARK5 is involved in hypoxia is unclear. The aim of present study was to investigate the association between the expression of ARK5 and that of hypoxia inducible factor 1-alpha (HIF1-alpha). Samples from 60 patients with colon cancer were collected and immunohistochemistry was used to detect the expression of ARK5 and HIF1-alpha within them. Western blot analysis and reverse transcription polymerase chain reaction were used to detect the expression of ARK5 in an SW480 cell line under hypoxic conditions. Cell Counting kit-8 and Transwell assays were used to study the function of ARK5 under hypoxic conditions. According to the immunohistochemistry results, ARK5 and HIF1-alpha staining was significantly associated with Tumor-Node-Metastasis stage, tumor grade, lymph node metastasis and liver metastasis. Spearman's correlation analysis revealed a correlation between the expression of ARK5 and that of HIF1-alpha. This finding was also verified under hypoxic conditions in the SW480 cell line, in which the expression of ARK5 increased over time. Further cellular function experiments revealed that suppression of ARK5 inhibited cell viability and migration under hypoxic conditions. The present study has suggested that ARK5 expression in colon cancer cells is upregulated by HIF1-alpha under hypoxic conditions and that ARK5 serves an important role in cell proliferation and migration under hypoxic stress. PMID- 29467885 TI - Paclitaxel plus nedaplatin vs. paclitaxel plus carboplatin in women with epithelial ovarian cancer: A multi-center, randomized, open-label, phase III trial. AB - The multi-center, randomized, open-label, phase III trial discussed in the present study was performed to compare the clinical outcomes of nedaplatin (NDP) plus paclitaxel, and carboplatin (CBP) plus paclitaxel for the treatment of epithelial ovarian cancer (EOC). In the current study, 182 patients with International Federation of Gynecology and Obstetrics (FIGO) stage II-IV EOC were randomly assigned to receive NDP plus paclitaxel or CBP plus paclitaxel at 3-week intervals for a total of six courses. The primary endpoints were progression-free survival rate (PFS) and overall survival rate (OS). The secondary endpoints were toxicity profiles. The median follow-up was 44.63 months [95% confidence interval (CI) 33.67-46.47 months] for the NDP group and 47.63 months (95% CI 45.13-49.07 months) for the CBP group. Overall, there was no significant difference in PFS or OS between the two groups (P=0.09 for PFS, and P=0.65 for OS). For the patients with FIGO stage III-IV EOC, the NDP plus paclitaxel regimen significantly prolonged PFS (P=0.02) but did not result in improved OS (P=0.53) when compared with the CBP group. The patients in the NDP plus paclitaxel group also exhibited a lower incidence rate of grade 3 or 4 leucopenia (P=0.03). Other hematological and non-hematological toxicity profiles were similar between the two groups. Compared with CBP plus paclitaxel regimens, NDP plus paclitaxel regimens achieved comparable survival outcomes and similar toxicity profiles. However, patients of FIGO stage III-IV EOC may experience more clinical benefits from NDP plus paclitaxel treatment, including a prolonged PFS and a lower incidence rate of leucopenia. Therefore, an NDP-based regimen may be an alternative choice when using platinum-based agents to treat EOC. PMID- 29467886 TI - Primary intrapulmonary solitary fibrous tumours. AB - Due to the extreme rarity of primary intrapulmonary solitary fibrous tumours (SFTs), their clinical course, imaging characteristics, diagnosis, treatment and prognosis are poorly understood. The present study therefore assessed the diagnosis and management of primary intrapulmonary SFTs and systematically reviewed previously reported cases in the literature. A total of 5 patients who underwent resection for primary intrapulmonary SFTs were enrolled in the present study and their clinical course, tumour characteristics, management and survival were assessed in this retrospective study. Relevant studies regarding primary intrapulmonary SFTs were searched using PubMed and tumour characteristics, clinicopathologic features, therapeutic strategy and survival outcomes were reviewed. Of the 5 cases, all were males, with a mean age of 57.6 years (range, 37-68 years). All patients were asymptomatic and were identified incidentally on routine computed tomography examination. A total of 3 patients underwent thoracotomy and 2 patients underwent video-assisted thoracoscopic surgery. All tumours were completely resected. Postoperative haemorrhage occurred in 1 patient and he received surgical intervention for haemostasis. The average hospital stay was 15 (4-22) days, and no mortality occurred. The mean length of the postoperative follow-up was 37.6 (1-67) months. One patient was lost to follow up, and 4 patients were asymptomatic. A total of 19 studies were identified from database searches. They included a total of 45 patients: Twenty-three males and 22 females (mean age, 59.4 years; range, 7-81 years). A total of 12 patients were asymptomatic, and pain and coughing were the major symptoms. Five, one, two, four, and 17 tumours occurred in the right upper lobe, right middle lobe, right lower lobe, left upper lobe and left lower lobe, respectively. A total of 39 patients underwent surgery, 1 patient underwent radiotherapy, and 1 patient underwent radiofrequency ablation. A total of 22 patients were followed up and the mean length of the postoperative follow-up was 48 (1-168) months. One patient was diagnosed with chest wall metastases, and 5 patients succumbed to mortality. To conclude, primary intrapulmonary SFTs are extremely rare and typically identified incidentally. The present findings indicated that the left lower lobe was the most common site location and complete surgical resection is a safe and effective treatment. PMID- 29467887 TI - Role and underlying mechanism of SPATA12 in oxidative damage. AB - Spermatogenesis-associated gene 12 (SPATA12) functions as an inhibitor in spermatogenesis and tumorigenesis. Our previous study demonstrated that SPATA12 may be induced in tumor cells by ultraviolet (UV) C-mediated DNA damage, suggesting its importance in maintaining genomic integrity. In order to understand whether and how SPATA12 responds to oxidative damage, the present study established a cellular model of oxidative stress by detecting the effect of H2O2 on cell viability and intracellular superoxide dismutase activity, and the levels of glutathione and malondialdehyde (MDA). Quantitative polymerase chain reaction results demonstrated that H2O2 upregulated the expression of SPATA12, and a dual luciferase reporter gene assay indicated that transcription factor activator protein-1 (AP-1) was involved in the response of SPATA12 to oxidative stress. Through the exogenous expression of SPATA12, it was identified that SPATA12 decreased the level of reactive oxygen species and MDA, and also may reduce the degree of cellular oxidative damage and apoptosis induced by H2O2. In addition, resveratrol was demonstrated to increase the expression of SPATA12 by activating AP-1, and it may be used as a nontoxic activator of the SPATA12 gene. In conclusion, these results suggest that SPATA12 is upregulated by oxidative stress via AP-1, and that the exogenous expression of SPATA12 protects against H2O2-induced oxidative damage and apoptosis. PMID- 29467888 TI - Characteristics of breast metastases from non-breast solid tumors in 22 patients from a southern Chinese population. AB - Breast metastases from solid non-breast tumor types are rare; however, they should be always considered in the differential diagnosis of a breast lesion owing to the associated poor patient prognosis and the requirement of different therapeutic strategies compared with those used to treat primary breast cancer. The aim of the current study was to summarize the characteristics of metastases to the breast in a southern Chinese population. The medical records and pathological sections of 22 patients with pathologically confirmed extra-mammary metastases to the breast that presented to Sun Yat-sen University Cancer Center between January 2000 and December 2015 were retrospectively reviewed. The median age of onset for breast metastasis was 43 years (range, 10-62 years) and 19 (86.4%) patients had a known history of a primary tumor. The mean interval from diagnosis of the primary tumor to breast metastasis was 16.5 months (range, 6-56 months). A unilateral (45.5% left, 36.4% right), upper outer quadrant (15/22, 68.2%) lesion of the breast was most frequently initially detected by self checking (63.6%). The most common origin of the primary tumor was the lung (22.7%). Nasopharyngeal carcinoma accounted for a high proportion of the metastases (18.2%). The median duration of survival from the time of diagnosis of a breast metastasis was 14 months (range, 2-74 months). A total of 10 patients (45.5%) succumbed to the disease. The results also indicated that overall survival in patients that underwent surgery was improved compared with patients who did not undergo surgery. The results of the present study demonstrated that clinical history, imaging findings, pathology from the primary tumor and immunostaining were required in combination to establish an accurate diagnosis. Further investigation into the improvement of the prognosis of patients with metastases to the breast following surgery is required. PMID- 29467889 TI - Serum immunoglobulin E response as a marker for unfavorable prognosis following cholesteryl pullulan-MAGE A4 vaccination. AB - Since 2009, a cancer vaccine clinical trial was conducted with melanoma antigen gene-A4 as an immunogenic agent. The levels of IgG1, IgG2 and IgG3, which are known to be Type 1 T helper cell-associated antibodies, and the levels of IgG4 and IgE, which are known to be Type 2 T helper cell-associated antibodies, were measured and used as biomarkers for predicting therapeutic effect. The results of the present study indicated a strong positive correlation between IgG2 and IgG4, with a correlation coefficient of R=0.808 (P<0.0001). The survival time of patients in which IgE responses were induced was significantly shorter compared with the survival time of patients with no IgE induction. The results of the present study suggest that caution is required when antigen-specific IgE responses are induced during cancer vaccination therapy. PMID- 29467890 TI - Dosimetric comparison between IMRT and VMAT in irradiation for peripheral and central lung cancer. AB - The aim of the present study was to compare intensity-modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT) in irradiation of lung cancer. Plans of 14 patients were compared. The results demonstrated that in peripheral lung cancer, V5 (%) of the lung in partial-arc (PA)-VMAT was decreased compared with IMRT, single-arc (SA)-, and double partial-arc (2PA)-VMAT. V30 (%) of the lung in IMRT was decreased compared with SA-, PA- and 2PA-VMAT. In the case of planning target volume (PTV) not encompassing the mediastinum in central lung cancer, the conformality index (CI) and heterogeneity index (HI) of SA-VMAT was improved compared with IMRT, PA-, and 2PA-VMAT. The received dose of heart in SA VMAT was higher compared with IMRT, PA- and 2PA-VMAT. V30 (%) and V5 (%) of the lung in IMRT was higher compared with SA-, PA- and 2PA-VMAT; V10 (%) of the lung in 2PA was decreased compared with IMRT, SA- and PA. In the case of PTV encompassing the mediastinum in central lung cancer, the HI and CI of 2PA was improved compared with IMRT, SA- and PA-VMAT. The received dose of heart in 2PA was higher compared with IMRT, SA- and PA-VMAT. V30 (%) and V5 (%) of the lung in 2PA-VMAT was higher compared with IMRT, SA- and PA-VMAT. V20 (%) of the lung in 2PA was decreased compared with IMRT, SA- and PA-VMAT. In conclusion, it may be necessary to classify the radiotherapy plans of lung cancer into three categories including peripheral lung cancer, PTV not encompassing the mediastinum of central lung cancer, and PTV encompassing the mediastinum of central lung cancer. Each of IMRT, SA-VMAT, PA-VMAT, 2PA-VMAT strategy had individual advantages, and therefore it may be crucial to employ different planning techniques for different disease classifications and OAR requirements. PMID- 29467891 TI - Prognostic analysis of hepatocellular carcinoma on the background of liver cirrhosis via contrast-enhanced ultrasound and pathology. AB - The aim of this study was to analyze the correlation between the quantitative parameters of contrast-enhancement ultrasound for primary hepatocellular carcinoma (HCC) and biological manifestations of tumor (Ki-67), and to explore the related risk factors of primary hepatocellular carcinoma, so as to provide the theoretical basis for the further study on contrast-enhancement ultrasound manifestations, clinical features and prognosis of HCC. The patients with HCC confirmed by operation or puncture were collected, and those with the background of liver cirrhosis and immunohistochemical staining for tumor sample sections were selected. H&E staining sections of pathological tissues of tumor samples were observed, whether there was any microvessel invasion (MVI) was recorded, the microvessel density (MVD) was counted and the recurrence situations after liver cancer operation was followed up. The change in size of tumor at arterial phase in contrast-enhancement ultrasound, enhancement mode and form at arterial phase, and whether there were tortuous vessels inside or not, and the enhancement intensity, extinction time and extinction intensity at portal phase were observed. The relationship between the parameters of contrast-enhancement ultrasound and Ki-67, AFP, MVD, MVI, tissue differentiation degree of tumor samples and recurrence was analyzed. Under the background of liver cirrhosis, there were significant differences in different enhancement modes and quantification parameters of contrast-enhancement ultrasound for HCC with different expression of Ki-67. Those with obvious tumor enlargement, inhomogeneous enhancement at arterial phase and irregular enhancement form at arterial phase after contrast-enhancement ultrasound had a high incidence of positive Ki-67 and a high early recurrence rate. The inhomogeneous enhancement at arterial phase might predict the proliferative activity and recurrence time of tumor cells; irregular enhancement form at arterial phase might indicate tumor MVI; and the low enhancement of tumor at portal phase may predict a lower degree of tissue differentiation, a higher tumor malignancy and poor prognosis. The incidence of positive Ki-67 under the background of liver cirrhosis is high, indicating poor prognosis. The enhancement mode and parameters of contrast enhancement ultrasound for HCC may help evaluate the clinical biological manifestations of HCC and predict the postoperative recurrence of HCC. PMID- 29467892 TI - Transcription factor PU.1 is involved in the progression of glioma. AB - Glioma is a severe disease of the central nervous system. Although previous studies have identified the important role of the immune response in association with tumor intervention, it is still unknown whether PU.1, a transcription factor known for its role in myeloid differentiation and immune responses, is involved in the progression of glioma. In the present study, we found a significant increase in SPI1, the gene that encodes PU.1, in samples from patients with glioma. Through genotype-phenotype association analysis several candidate factors that may mediate the role of PU.1 in glioma were identified. To further validate the association between PU.1 and glioma we found that the expression of BTK, a potential target of PU.1, was also upregulated in patients with glioma. We also demonstrated that various biological pathways could be involved in PU.1 associated glioma by analyzing these potential targets in the Reactome database. These results provide evidence that PU.1 could serve a role in the progress of glioma through its transcriptional targets in multiple signaling pathways. Therefore, in addition to its role in hematopoietic linage development and leukemia, PU.1 appears to be involved in the regulation of glioma and potentially in other malignant cancers. PMID- 29467893 TI - IFN-gamma induces the upregulation of RFXAP via inhibition of miR-212-3p in pancreatic cancer cells: A novel mechanism for IFN-gamma response. AB - Previous studies have demonstrated that pancreatic cancer-derived microRNA (miR) 212-3p can inhibit the expression of regulatory factor X-associated protein (RFXAP), an important transcription factor for major histocompatibility complex (MHC) class II, and thereby lead to downregulation of MHC class II in dendritic cells. It has also been established that interferon (IFN)-gamma can increase the expression of MHC class II in immune cells. It was therefore hypothesized that IFN-gamma can inhibit miR-212-3p expression in pancreatic cancer, leading to the upregulation of RFXAP and MHC class II expression. This may represent a novel molecular mechanism underlying the use of IFN-gamma in immunotherapy. Data from the present study revealed that miR-212-3p was inhibited by IFN-gamma in a dose and time-dependent manner in the pancreatic ductal adenocarcinoma cell line PANC 1. RFXAP and MHC class II expression were increased following IFN-gamma stimulation. A luciferase assay was performed to validate RFXAP as a target gene of miR-212-3p. The expression levels of RFXAP and MHC class II were decreased by miR-212-3p mimics and increased by miR-212-3p inhibitors. In PANC-1 cells transfected with miR-212-3p mimics, IFN-gamma stimulation could not increase the RFXAP and MHC class II. The results from the present study suggest that IFN-gamma increases RFXAP and MHC class II expression by inhibiting miR-212-3p. To the best of our knowledge, this is the first report of this novel molecular mechanism underlying the effects of IFN-gamma on pancreatic cancer, which may aid with the development of immunotherapies for patients with pancreatic cancer. PMID- 29467894 TI - Association between receptor interacting serine/threonine kinase 2 polymorphisms and gastric cancer susceptibility. AB - The present study aimed to investigate whether single nucleotide polymorphisms in receptor interacting serine/threonine kinase 2 (RIPK2), which encodes a component of the nucleotide binding oligomerization domain containing 2-RIP2 pathway, may compromise the innate immune response to Helicobacter pylori infection, leading to increased susceptibility to gastric cancer in the Japanese population. The present case control study investigated the associations between RIPK2 single nucleotide polymorphisms and gastric mucosal inflammation, atrophy and cancer susceptibility in 528 patients with gastric cancer and 697 patients without gastric malignancies on upper gastro-duodenal endoscopy. Overall, the RIPK2 rs16900627 minor allele was significantly associated with the susceptibility to gastric cancer [OR, 1.37; 95% confidence interval (CI), 1.06-1.77; P=0.016], particularly of the intestinal type (OR, 1.53; 95% CI, 1.13-2.07; P=0.0062). It was also significantly associated with gastric mucosal atrophy (OR, 1.83; 95% CI, 1.14-2.93; P=0.011). When assessing the severity of chronic gastritis using the updated Sydney system, the activity and inflammation scores, as well as atrophy and metaplasia scores, were significantly higher in rs16900627 minor allele carriers compared with wild-type homozygotes. In patients younger than 60 years old, the pepsinogen I/II ratio was significantly lower in rs16900627 minor allele carriers compared with wild-type homozygotes (P=0.037). The rs16900627 minor allele is associated with the severity of gastric mucosal inflammation and the development of gastric mucosal atrophy. Carriers of this allele may have an increased risk for the development of gastric cancer, particularly of the intestinal type. PMID- 29467895 TI - Clinicopathological and functional implications of the inhibitor of apoptosis proteins survivin and XIAP in esophageal cancer. AB - Based on their overexpression and important roles in progression and therapy resistance in malignant diseases, the inhibitor of apoptosis protein family (IAP) members, survivin and X-linked inhibitor of apoptosis protein (XIAP), represent attractive candidates for targeted therapy. The present study investigated the prognostic and biological relevance of survivin and XIAP in esophageal squamous cell carcinoma (ESCC) and esophageal adenocarcinoma (EAC). Survivin and XIAP expression was analyzed by immunohistochemistry using tissue microarrays containing 120 ESCC and 90 EAC samples as well as the corresponding non neoplastic esophageal mucosa samples. IAP expression levels were then correlated to clinicopathological parameters and overall survival to identify any associations. In addition, esophageal cancer cell lines were treated with the survivin inhibitor YM155, and the XIAP inhibitors Birinapant and GDC-0152 in vitro. Survivin and XIAP expression were significantly increased in EAC and ESCC when compared with tumor-adjacent mucosa. In patients with ESCC XIAP expression was associated with female gender and advanced tumor stages, and nuclear survivin expression was associated with poor grading. High XIAP expression was identified as an independent negative prognostic marker in ESCC. By contrast, XIAP inhibitors did not affect cancer cell viability in vitro, and the small molecule survivin inhibitor YM155 significantly reduced cell viability and proliferation in esophageal cancer cell lines. Western blot analysis revealed a dose dependent decrease of survivin accompanied by an increased poly (adenosine diphosphate ribose) polymerase cleavage following YM155 treatment. These findings underline the potential role of survivin and XIAP in the oncogenesis of esophageal cancer and provide a rationale for future clinical studies investigating the therapeutic efficacy of IAP directed therapies in patients with esophageal cancer. PMID- 29467896 TI - 17beta-estradiol regulates the malignancy of cancer stem-like cells derived from the MCF7 cell line partially through Sox2. AB - As a major common malignant tumor in women, the malignant behavior of breast cancer, which includes tumorigenesis and metastasis, is associated with estrogen, particularly 17beta-estradiol (E2). With accumulating evidence demonstrating that cancer stem-like cells (CSCs) serve a function in the malignant behavior of breast cancer, including metastasis, recurrence and chemoresistance, the effects of E2 on the physiological processes of CSCs have been attracting more attention. In the present study, in order to investigate the effects of E2 on CSCs, CSCs from the MCF7 breast cancer cell line were isolated and treated with 1, 10 and 50 nM E2. Detection of cell proliferation following E2 treatment revealed that 10 nM E2 treatment inhibited cell proliferation, whereas 50 nM E2 treatment resulted in the induction of apoptosis on CSCs. In order to further investigate the effects of E2 treatment on migration, colony formation and the self-renewal capacity of CSCs in vitro, cells were treated with 1 and 10 nM E2. As expected, compared with mock group, the self-renewal capacity of the CSCs was slightly increased by 10 nM E2 treatment, while 1 nM exhibited no observable effect. E2 treatment demonstrated different effects on the proliferation, migration, colony formation and self-renewal capacity of CSCs in a dose-dependent manner. PMID- 29467897 TI - Prognostic significance of c-Met, beta-catenin and FAK in patients with hepatocellular carcinoma following surgery. AB - The present study aimed to investigate the prognostic value of specific molecular markers in patients with hepatocellular carcinoma (HCC) who had received surgery. Immunohistochemical analysis was used to measure the expression of hepatocyte growth factor receptor (c-Met), beta-catenin and focal adhesion kinase (FAK) in patients with HCC. c-Met expression was identified to be high in patients with larger tumors, higher alpha-fetoprotein (AFP) levels, higher Edmondson grades, portal vein invasion and higher tumor-node-metastasis (TNM) stages. FAK expression was high in patients with portal vein invasion, higher Edmondson grades and higher TNM stages. beta-catenin expression was high in patients with larger tumors, hepatitis B virus (HBV) infection, portal vein invasion, higher Edmondson grades and higher TNM stages. Following multivariate analysis, FAK (P=0.002) and beta-catenin (P=0.006) expression levels were demonstrated to be significantly associated with Edmondson grade. Additionally, the tumor size (P=0.009) and HBV infection status (P=0.002) were revealed to be associated with beta-catenin expression. Kaplan-Meier survival curve analysis demonstrated that patients with HCC with higher FAK expression, higher beta-catenin expression, portal vein invasion, higher Edmondson grades, higher TNM stages, younger ages and higher AFP levels had significantly poorer prognoses. Cox's regression analysis revealed that the survival period was correlated with the Edmondson grade, age, AFP level, and FAK and beta-catenin expression. Univariate analysis of c-Met, beta-catenin and FAK identified a significant correlation between FAK and beta-catenin (P=0.015). Correlation analysis revealed no significant correlation between the three molecular markers, but beta-catenin and c-Met were markedly correlated (P=0.052). No significant correlation between FAK, c-Met or beta-catenin expression was identified. FAK and beta-catenin expression demonstrated a correlation with a range of clinicopathological factors, and high FAK and beta-catenin expression levels were identified to be correlated with a poor survival rate of patients with HCC. Thus, patients with higher FAK and beta catenin expression may require more aggressive therapy. The results of the present study suggest that FAK and beta-catenin expression possess more prognostic value than c-Met expression in patients with HCC. PMID- 29467898 TI - Anticancer effect of miR-96 inhibitor in bladder cancer cell lines. AB - The present study aimed to investigate the role of microRNA-96 (miR-96) in the proliferation, invasion and apoptosis of bladder cancer cell lines, and the associated mechanisms. The expression of miR-96 and human ether-a-go-go-related (HERG1) potassium channel in the normal uroepithelium SV-HUC-1 cell line, and bladder cancer T24 and 5637 cell lines were examined using reverse transcription polymerase chain reaction or/and western blotting. Transfection with miR-96 inhibitor or scrambled control (SC) was used to study the biological activities of miR-96 in bladder cancer cell lines. MTT, flow cytometric and Transwell assays were applied to detect cell viability, apoptosis and invasion, respectively. A dual-luciferase reporter assay was applied to determine the association between miR-96 and HERG1 expression. As demonstrated, miR-96 was highly expressed in the two bladder cancer cell lines, particularly in T24 cells. Following transfection with miR-96 inhibitor, miR-96 expression was significantly reduced in the T24 cell line, compared with SC. The miR-96 inhibitor suppressed cell proliferation and invasion, promoted apoptosis and arrested the cell cycle at the G1 phase. Consistently, HERG1 was also highly expressed in the two bladder cancer cell lines at the mRNA and protein level, but not in the normal uroepithelium cell line. The miR-96 inhibitor also significantly decreased HERG1 expression compared with SC. The results of the dual-luciferase reporter assay indicated that miR-96 directly targeted wild-type HERG1. In conclusion, miR-96 inhibitor exhibited anticancer effects on bladder cancer cells by inhibiting proliferation and invasion of cells, and promoting their apoptosis. HERG1 was an important target of miR-96. These results provided experimental evidence supporting miR-96 as a therapeutic target for patients with bladder cancer. PMID- 29467899 TI - TNF-alpha promotes colon cancer cell migration and invasion by upregulating TROP 2. AB - High levels of tumor-associated calcium signal transduction protein (TROP)-2 have been demonstrated to be strongly associated with tumor necrosis factor (TNF) alpha levels in colon cancer. In the present study, the effect of TNF-alpha on the regulation of TROP-2 expression and its effect in colon cancer cell migration and invasion were investigated in vitro. TROP-2 protein levels were evaluated in HCT-116 human colon cancer cells cultured with various concentrations of TNF alpha using western blot analysis. Changes in the migratory and invasive potential of the cells were evaluated using a wound healing and transwell assay, respectively. Then, TROP-2 expression was downregulated in cells by use of siRNA, and TROP-2 knockdown was confirmed at the mRNA and protein level by reverse transcription-quantitative polymerase chain reaction and western blotting, respectively. The migration and invasion potential of cells transfected with TROP 2 siRNA was also evaluated. Levels of several mitogen-activated protein kinase proteins, namely p38, c-Jun N-terminal kinase (JNK) and extracellular signal regulated kinase (ERK), were detected in cells treated with TNF-alpha using western blot analysis. The results demonstrated that TROP-2 protein levels increased in cells treated with lower concentrations of TNF-alpha, but decreased in cells treated with higher concentrations of TNF-alpha, compared with untreated control. Maximum TROP-2 levels were observed in cells treated with 20 ug/l TNF alpha. Migration and invasion were enhanced in cells treated with 20 ug/l TNF alpha. When TROP-2 was silenced in colon cancer cells by siRNA, migration and invasion were significantly decreased compared with control cells. TNF-alpha stimulation activated the ERK1/2 pathway, but did not significantly affect p38 and JNK phosphorylation levels. Treatment with a specific ERK1/2 inhibitor suppressed the TNF-alpha-induced upregulation of TROP-2 and the TNF-alpha-induced colon cancer cell migration and invasion. In conclusion, the present results demonstrated that low concentrations of TNF-alpha significantly enhanced colon cancer cell migration and invasion by upregulating TROP-2 via the ERK1/2 signaling pathway. PMID- 29467900 TI - Overexpression of RHEB is associated with metastasis and poor prognosis in hepatocellular carcinoma. AB - Aberrant expression of Ras homolog enriched in brain (RHEB) has been observed in a variety of cancer tissues and is closely associated with clinicopathological features. However, the expression profile of RHEB in patients with hepatocellular carcinoma (HCC) and its clinical signature with underlying mechanisms have not been explored thus far. To analyze the association between RHEB expression and clinicopathological features, the RHEB expression levels were determined in the present study using gene microarrays, immunohistochemistry and western blotting in 60 liver cancer tissues and 35 normal liver tissues. Downregulation of RHEB expression in liver cancer cell lines was achieved by RNA interfering technology to explore its biological function in HCC. RHEB expression was high in liver cancer tissues, with an increase of 2.00+/-0.19-fold compared with normal tissues and of 2.00+/-0.27-fold compared with adjacent non-cancer tissues. RHEB expression increased along with the clinical staging of HCC, and the overall survival and mortality of patients were closely correlated to RHEB levels, micro vascular invasion, hepatitis B virus-DNA titer, tumor differentiation and pathological satellites (P<0.05). After knocking down RHEB in SMMC-7721 cells, the growth of liver cancer cells was significantly reduced. The majority of cells were blocked in S-phase, and their colony-forming and proliferating abilities significantly decreased (P<0.05). In vivo, upon downregulation of RHEB expression, the tumorigenic ability of HCC significantly decreased (P<0.05). These data suggest that RHEB expression is a significant prognostic factor and may be important in HCC cell growth. The present study highlights the importance of RHEB as a novel prognostic marker of HCC. PMID- 29467902 TI - Remodeling and spacing factor 1 overexpression is associated with poor prognosis in renal cell carcinoma. AB - The present study aimed to assess the expression and prognostic significance of remodeling and spacing factor 1 (RSF1; HBXAP) in renal cell carcinoma (RCC). RSF1 expression was analyzed using immunohistochemistry on tissue samples from a consecutive series of 137 patients with RCC who underwent tumor resection between November 2000 and March 2004. The associations between RSF1 expression, clinicopathological factors and patient survival were investigated. Immunohistochemistry revealed that RSF1 was highly expressed in 43.1% (59/137) of the RCC samples. RSF1 expression levels were associated with the T stage of the Tumor-Node-Metastasis grading system. Kaplan-Meier survival analysis indicated that high RSF1 expression in RCC was significantly associated with a poor prognosis. Multivariate analysis revealed that RSF1 expression is an independent prognostic parameter for the duration of overall survival of patients with RCC. The results demonstrated that a high expression level of RSF1 in RCC is associated with advanced tumor stages and a poor prognosis. To the best of our knowledge, the present study provides novel evidence of the biological significance of RSF1 expression in RCC. PMID- 29467901 TI - Ubiquitin-specific protease 15 promotes tumor cell invasion and proliferation in glioblastoma. AB - Glioblastoma multiforme (GBM) is one of the most aggressive types of brain tumor worldwide. Despite the advances made in treatment and research, the median survival time for GBM patients remains <1.5 years, providing impetus for the identification of potential novel therapeutic target genes to improve GBM treatment. The deubiquitinating enzyme ubiquitin specific peptidase 15 (USP15) has emerged as a pro-oncogenic factor; however, its function in GBM has yet to be fully elucidated. The present study sought to determine whether or not USP15 is implicated in GBM cell invasion and proliferation. Following the depletion of USP15 in U87-MG and U251-MG cells by lentivirus-mediated USP15 short hairpin RNA (shRNA), the invasiveness of glioma cells was investigated. The results of the present study demonstrated that glioma cells expressing USP15 shRNA exhibited significantly lower invasiveness than cells that did not express USP15 shRNA. Additionally, USP15 depletion led to the upregulation of E-cadherin and downregulation of the mesenchymal markers, N-cadherin and vimentin. Furthermore, the influence of USP15 on glioma cell proliferation was investigated and depletion of USP15 resulted in a marked reduction in cell proliferation. Taken together, the findings of the present study clearly support the hypothesis that USP15 renders GBM cells capable of invasion and proliferation. PMID- 29467903 TI - Effect of selective inhibition of aquaporin 1 on chemotherapy sensitivity of J82 human bladder cancer cells. AB - The occurrence of resistance to mitomycin C (MMC) often limits its clinical effectiveness. Combination therapy thus is employed to overcome this treatment resistance. The present study aimed to establish a novel J82 bladder cancer cell line so as to study the effect of inhibition of aquaporin 1 (AQP-1) on chemotherapy sensitivity of J82 bladder cancer cells. A novel J82 bladder cancer cell line whose expression of AQP-1 is inhibited was established through transfection of J82 cells with newly constructed recombinant plasmid. The resulting cell line was designated J82-short hairpin (sh)AQP1 and was subjected to further analyses together with J82 cell line. Reverse transcription-polymerase chain reaction was used to quantify the expression of AQP-1mRNA in the cells; cell viability was analyzed with MTT assay and apoptosis was measured by flow cytometry. The expression of cell proliferation and cell apoptosis-associated proteins, proliferating cell nuclear antigen (PCNA), B cell lymphoma 2 (Bcl-2), Bcl-2 associated X protein (Bax) and caspase-3, were detected by Western blot. A statistically significant decrease in the transcription and expression of AQP1 was observed in the J82-shAQP1 cells as compared with J82 cells. J82-shAQP1 cells treated by MMC, also had a lower cell viability than J82 cells treated by MMC and showed enhanced apoptosis. Western blot analysis revealed J82-shAQP1 cells treated by MMC had less expression of PCNA, lower bcl-2/Bax ratio and more expression of caspase-3 as compared with the J82 cells treated by MMC. Selective inhibition of AQP-1 enhanced MMC chemotherapy sensitivity of J82 bladder cancer cells, suggesting combination of AQP-1 inhibition with MMC treatment as a promising treatment strategy to overcome bladder cancer treatment resistance. PMID- 29467904 TI - Human sodium iodide transporter gene-mediated imaging and therapy of mouse glioma, comparison between 188Re and 131I. AB - Novel treatment options are urgently required for patients with glioma who are not effectively treated through standard therapy. Human sodium iodide symporter (hNIS) is a molecular target of certain tumors types. Compared with 131I, 188Re possesses a higher energy and shorter half-life; therefore, the effects of 188Re and 131I were compared in hNIS-mediated gene imaging and therapy in the present study. Recombinant human brain glioma cell line U87 was transfected with a recombinant lentiviral vector containing hNIS (U87-hNIS). U87-0 cell line transfected with blank lentivirus was prepared as a control. In vitro, the 188Re and 131I uptake of U87-hNIS cells were 21.3-times and 25.9-times that of the control groups, however the excretion rate of the two nuclides was very rapid, and the half-life was only ~4 min. Sodium perchlorate inhibited hNIS-mediated 188Re and 131I uptake to levels observed in the control groups. 188Re and 131I were able to kill U87-hNIS cells selectively, with a survival of only 21.6 and 36.2%, respectively. U87-hNIS nude mice appeared to accumulate 188Re, with a ratio of radioactivity counts between tumor and non-tumor sites of ~13.5 compared with 10.3 of 131I 1 h after radionuclide injection. In contrast with in vitro studies, U87-hNIS cells demonstrated a notable increase in 188Re retention in vivo, even 24 h after 188Re injection. U87-hNIS cells also exhibited increased 131I retention in vivo; however, as the time increased, 131I was rapidly released with the tumor no longer able to be imaged 24 h after 131I injection. Following treatment, U87-hNIS tumors experienced a volume reduction of 24.1%, whereas U87-0 cells demonstrated an increase of 28.8%. 188Re and 131I were revealed to be effective at decreasing tumor volume compared with the control. However, 188Re was significantly more potent compared with 131I (P<0.01). The present study indicated that the U87-hNIS cell line is sufficient to induce specific 188Re and 131I uptake, which may kill cells in vitro and in vivo. 188Re exhibited an increased retention time in vivo compared with 131I, which facilitates the imaging and therapy of U87-hNIS tumors. PMID- 29467905 TI - [18F]FDG-PET/CT and MRI for initial pelvic lymph node staging in patients with cervical carcinoma: The potential usefulness of [18F]FDG-PET/MRI. AB - The current study aimed to determine the optimum diagnostic imaging technique out of magnetic resonance imaging (MRI), 18F-fludeoxyglucose positron emission tomography/computed tomography ([18F]FDG-PET/CT, otherwise known as PET/CT) and [18F]FDG-PET/MRI (otherwise known as PET/MRI) for the pelvic lymph node staging (N-staging) of untreated cervical carcinoma (CC). A total of 27 patients were included in the present study. All patients had undergone pre-treatment with PET/CT and MRI <=45 days prior to undergoing a lymphadenectomy. The results from PET (separated from PET/CT), MRI and the statistically combined results of (virtual) PET/MRI were compared to those from histological analyses (the gold standard). A per-patient-based analysis of the detection of pelvic lymph node metastases indicated that PET/MRI had a sensitivity of 64%. The specificity of PET/CT and MRI were 69 and 62%, respectively. The positive predictive value (PPV) was 69 and 64% for PET/CT and MRI, respectively. The negative predictive value (NPV) was 64 and 62% for PET/CT and MRI, respectively. The sensitivity of the PET guided PET/MRI and the MRI-guided PET/MRI was 64% for both. The specificity of the PET-guided PET/MRI and the MRI-guided PET/MRI was 77 and 62%, respectively. The PPV was 75% for PET-guided PET/MRI and 64% for MRI-guided PET/MRI, and the NPV was 67 and 62%, respectively. PET/CT and the virtual PET/MRI exhibited the same low sensitivity (64%). PET/MRI exhibited slightly better results than PET/CT regarding specificity (77 vs. 69%, respectively), PPV (75 vs. 69%, respectively) and NPV (67 vs. 64%, respectively). The results of the present study suggested that PET/CT and MRI are not optimal diagnostic modalities, and that PET/MRI does not necessarily lead to better results than PET/CT, in the pelvic N-staging of CC. PMID- 29467906 TI - beta-elemene enhances anticancer and anti-metastatic effects of osteosarcoma of ligustrazine in vitro and in vivo. AB - The present study aimed to determine the anticancer effects of the combination of beta-elemene and ligustrazine in vitro as well as in in vivo. Following evaluation using an MTT assay, beta-elemene, ligustrazine and the beta-elemene ligustrazine combination treatments all exhibited the capacity to inhibit the growth of OS-732 cells, with inhibitory rates of 43.3, 54.4, and 75.0%, respectively. Using a flow cytometry assay, it was determined that the beta elemene-ligustrazine combination possessed the highest apoptotic rate (30.6%). Furthermore, beta-elemene-ligustrazine combination treatment resulted in the highest downregulation of G protein-coupled receptor 124, vascular endothelial growth factor, matrix metallopeptidase (MMP)-2 and MMP-9 mRNA, and protein expression levels. In addition, the combined treatment led to an increase in the mRNA and protein expression of endostatin, TIMP metallopeptidase inhibitor (TIMP) 1 and TIMP-2 in OS-732 cells. Additionally, beta-elemene-ligustrazine caused a decrease in nuclear factor-kappaB, interleukin-8, C-X-C motif chemokine receptor 4 and urokinase-type plasminogen activator mRNA expression, as well as an increase in caspase-3, caspase-8, and caspase-9 mRNA expression. In vivo, the beta-elemene-ligustrazine combination was able to reduce the weight and the bulk of the tumor in BALB/c-nu/nu nude mice compared with any other group. All the results described above regarding changes to mRNA and protein expression were further confirmed in vivo in the tumor tissue of mice. The results of the present study have suggested that the combination of beta-elemene-ligustrazine exhibits greater anticancer effects compared with beta-elemene- or ligustrazine-alone treatment. PMID- 29467907 TI - TGFBR1*6A is a potential modifier of migration and invasion in colorectal cancer cells. AB - Type 1 transforming growth factor beta receptor (TGFBR1)*6A, a common hypomorphic variant of TGFBR1, may act as a susceptibility allele in colorectal cancer. However, the contribution of TGFBR1*6A to colorectal cancer development is largely unknown. To test the hypothesis that TGFBR1*6A promotes colorectal cancer invasion and metastasis via Smad-independent transforming growth factor-beta (TGF beta) signaling, the effect of TGFBR1*6A on the invasion of colorectal cancer cells was assessed. pCMV5-TGFBR1*6A-HA plasmids were transfected into SW48 and DLD-1 cells by Lipofectamine-mediated DNA transfection. The effect of TGF-beta1 on the proliferation of SW48 and DLD-1 cells transfected with TGFBR1*6A was determined by MTT assay. The effects of the TGF-beta1 on the invasion of the transfected SW48 and DLD-1 cells were determined using Matrigel-coated plates. Transforming migrating chambers were used to determine the effects of TGF-beta1 on the migration of the transfected SW48 and DLD-1 cells. Western blot analysis was used to determine the expression of phosphorylated (p-) extracellular-signal regulated kinase (ERK), p-P38 and p-SMAD family member 2 in SW48 cells. Using transfected TGFBR1*6A SW48 and DLD-1 cell lines our group demonstrated that, in comparison with TGFBR1*9A, TGFBR1*6A is capable of switching TGF-beta1 growth inhibitory signals into growth-stimulatory signals which significantly increased the invasion of SW48 and DLD-1 cells. Functional assays indicated that TGFBR1*6A weakened Smad-signaling but increased ERK and p38 signaling, which are crucial mediators of cell migration and invasion. From this, it was possible to conclude that TGFBR1*6A enhanced SW48 cell migration and invasion through the mitogen activated protein kinase pathway and that it may contribute to colorectal cancer progression in a TGF-beta1/Smad signaling-independent manner. This suggests that TGFBR1*6A may possess oncogenic properties and that it may affect the migration and invasion of colorectal cancer cells. PMID- 29467908 TI - Long non-coding RNA SPRY4-IT1 promotes the proliferation and invasion of U251 cells through upregulation of SKA2. AB - The long non-coding RNA SPRY4-intronic transcript 1 (SPRY4-IT1) has been shown to promote the progression of cancer; however, the role of SPRY4-IT1 in glioma remains unclear. The present study demonstrated that SPRY4-IT1 expression was markedly increased in glioma tissues and cells compared with normal brain tissues, whereas knockdown of SPRY4-IT1 inhibited cell proliferation, migration, and invasion in U251 cells. Spindle and kinetochore associated complex subunit 2 (SKA2) was found to be a target of SPRY4-IT1 and was downregulated by SPRY4-IT1 knockdown. Additionally, SPRY4-IT1 expression was positively correlated with SKA2 in glioma tissues. To the best of our knowledge, the present study provides the first demonstration that SKA2 may have an oncogenic role in U251 cells. These results indicate that SPRY4-IT1 may serve a notable role in the molecular etiology of glioma and represents a potential target in glioma therapy. PMID- 29467909 TI - Apoptosis-sensitizing activity of birinapant in head and neck squamous cell carcinoma cell lines. AB - Inhibitor of apoptosis proteins, which are overexpressed in head and neck squamous cell carcinoma (HNSCC), may cause therapeutic resistance. Using SMAC mimetic compounds, including birinapant, to degrade and/or inhibit these proteins and sensitize apoptosis may enhance therapies in HNSCC. Fas expression was analyzed in nine HNSCC cell lines and one keratinocyte cell line via flow cytometry. These cell lines were treated with Fas ligand-Fc (FasL) and birinapant, a bivalent SMAC mimetic, in mono and combination therapies. Cytotoxicity was measured using a crystal violet assay. Annexin V assay was performed for detection of apoptosis. The treatment efficacy of mono and combination therapies was statistically analyzed. Nonlinear regression analysis was performed to determine the inhibitory concentration (IC10) of birinapant. Fas expression was detected in each cell line tested. Mono treatment with FasL revealed minor to no apoptotic effects in the majority of the cell lines. Crystal violet and Annexin V staining revealed increased apoptosis rates for all cell lines following incubation with birinapant in mono treatment. Combination treatment with FasL and birinapant (IC10) revealed additional and synergistic effects in eight out of the ten cell lines. To the best of our knowledge, the present study provided the first evidence of the apoptosis-sensitizing activity of combination treatment with FasL and birinapant in HNSCC cell lines. PMID- 29467910 TI - Predictive value of inflammatory indexes on the chemotherapeutic response in patients with unresectable lung cancer: A retrospective study. AB - Chemotherapy is widely administered to patients with advanced lung cancer; however, data regarding chemotherapeutic sensitivity are limited. The present study aimed to investigate the predictive value of inflammatory indexes for chemotherapeutic efficacy in advanced lung cancer. Patients with stage III and IV unresectable lung cancer that were treated with first-line chemotherapy between January 2007 and December 2011 were retrospectively identified, and chemotherapeutic response was evaluated following 2 or 3 chemotherapy cycles. Prior to chemotherapy, hematologic data and clinicopathological parameters were collected using electronic medical records. The associations between the main inflammatory indexes [which included the pretreatment neutrophil count (PNC), neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR)] and the chemotherapeutic efficacy, as well as the prognostic value of the indexes, were analyzed. According to the receiver operating characteristic curve, PLR failed to reach diagnostic accuracy for overall chemotherapeutic response. PNC and NLR were each classified into two groups according to the cut-off values (4.635*109/l for PNC and 2.443 *109/l for NLR). The overall response rate was significantly higher in the low PNC [odds ratio, 3.261; 95% confidence interval (CI), 2.102-5.060; P<0.001, vs. high PNC] and low NLR groups (odds ratio, 1.596; 95% CI, 1.037 2.454; P=0.033, vs. high NLR). Univariate analyses showed that the high PNC (HR, 1.487) and high NLR groups (HR, 1.288) were associated with poor progression-free survival (PFS); however, NLR was considered statistically insignificant in multivariate analysis. In summary, high PNC and NLR values are associated with chemoresistance and an unfavorable prognosis, with the present study demonstrating that PNC has increased sensitivity when compared with other inflammatory indexes in predicting chemotherapeutic efficacy. Therefore, PNC has the potential to be used as a reliable and suitable predictor to stratify a high risk of chemoresistance in patients with stage III and IV unresectable lung cancer. PMID- 29467911 TI - Downregulation of the long non-coding RNA taurine-upregulated gene 1 inhibits glioma cell proliferation and invasion and promotes apoptosis. AB - Expression of the long non-coding RNA taurine-upregulated gene 1 (TUG1) is associated with various aggressive tumors. The present study aimed to investigate the biological function of TUG1 in regulating apoptosis, proliferation, invasion and cell cycle distribution in human glioma U251 cells. Lentivirus-mediated TUG1 specific microRNA was transfected into U251 cells to abrogate the expression of TUG1. Flow cytometry analysis was used to examine the cell cycle distribution and apoptosis of U251 cells. Cellular proliferation was examined using Cell Counting Kit-8 (CCK-8) assays and invasion was examined by Transwell assays. The apoptotic rate of cells in the TUG1-knockdown group was significantly higher than in the negative control (NC) group (11.58 vs. 9.14%, P<0.01). CCK-8 assay data demonstrated that the proliferative ability of cells within the TUG1-knockdown group was lower compared with that of the NC group. A Transwell invasion assay was performed, which revealed that the number of invaded cells from the TUG1 knockdown group was the less compared with that of the NC group. In addition, the G0/G1 phase population was significantly increased within the treated group (44.85 vs. 38.45%, P<0.01), as measured by flow cytometry. The present study demonstrated that the downregulation of TUG1 may inhibit proliferation and invasion, and promote glioma U251 cell apoptosis. In addition, knockdown of TUG1 may have an effect on cell cycle arrest. The data presented in the current study indicated that TUG1 may be a novel therapeutic target for glioma. PMID- 29467912 TI - pi-Electron systems containing Si=Si double bonds. AB - Sterically large substituents can provide kinetic stabilization to various types of low-coordinate compounds. For example, regarding the chemistry of the group 14 elements, since West et al. introduced the concept of kinetic protection of the otherwise highly reactive Si=Si double bond by bulky mesityl (2,4,6 trimethylphenyl) groups in 1981, a number of unsaturated compounds of silicon and its group homologs have been successfully isolated by steric effects using the appropriate large substituents. However, the functions and applications of the Si Si pi-bonds consisting of the 3ppi electrons on the formally sp2-hybridized silicon atoms have rarely been explored until 10 years ago, when Scheschkewitz and Tamao independently reported the model systems of the oligo(p phenylenedisilenylene)s (Si-OPVs) in 2007. This review focuses on the recent advances in the chemistry of pi-electron systems containing Si=Si double bonds, mainly published in the last decade. The synthesis, characterization, and potential application of a variety of donor-free pi-conjugated disilene compounds are described. PMID- 29467913 TI - Oncoplastic Reduction Pattern Technique Following Removal of Giant Fibroadenoma. AB - Objective: Oncoplastic surgery was developed to allow for large tumor excision and immediate breast reconstruction with the goal of optimal breast shape and symmetry. Although initially used in women who underwent lumpectomy for breast malignancy, these techniques can be useful for cosmetic issues caused by benign breast disease. We describe a modification of an inferior pedicle with Wise pattern reduction mammoplasty for oncoplastic reconstruction of a giant fibroadenoma. Methods: A 30-year-old woman with size 32 DD breasts was referred by the surgical oncologist with a biopsy-proven fibroadenoma of the right breast. Surgical oncology excised the mass, and immediate reconstruction was performed with an inferolateral pedicle Wise-pattern reduction technique. Results: Immediately postoperatively, the patient showed excellent symmetry. Follow-up postoperatively showed good wound healing, preserved symmetry, and a viable, sensate nipple. Conclusions: Oncoplastic breast reconstruction in a reduction pattern technique after giant fibroadenoma removal provides an excellent outcome, allowing for improved symmetry. PMID- 29467914 TI - Comprehensive Review and Case Study on the Management of Buried Penis Syndrome and Related Panniculectomy. AB - Objective: This paper discusses the various surgical techniques and outcomes associated with management of buried penis syndrome. Methods: Presented is the case of a 49-year-old man with morbid obesity, leading to massive panniculus and buried penis. We review our technique for reconstruction of the buried penis and treatment of the overlying large panniculus. Literature search was conducted to review current techniques in correcting buried penis syndrome. Results: The patient underwent a successful panniculectomy with removal of all excess skin and tissue. Thoughtful planning and coordination between plastic surgery and urology were paramount to externalize the penis for an excellent functional and cosmetic result. Conclusions: Management of a buried, hidden penis is complex and difficult. Patients are often obese and have poor hygiene due to the inability to cleanse areas that are entrapped by excessive fat. Following removal of the overhanging panniculus, satisfactory reconstruction of a hidden penis is possible when proper care is taken to adhere the base of the penis to the pubis. Split thickness skin grafts are often necessary but depend on the viability of the penile skin and whether it is restricting penile length. Complications with wound dehiscence and infection are not uncommon; however, patients generally recover well, are satisfied with results, and are reported to have fully regained urinary and sexual functions following surgical correction of the buried penis. PMID- 29467915 TI - Correction to: Neisseria lactamica Y92-1009 complete genome sequence. AB - [This corrects the article DOI: 10.1186/s40793-017-0250-6.]. PMID- 29467916 TI - Utility of endoscopic ultrasound and endoscopy in diagnosis and management of hepatocellular carcinoma and its complications: What does endoscopic ultrasonography offer above and beyond conventional cross-sectional imaging? AB - Hepatocellular carcinoma constitutes over 90% of the primary liver tumors, the rest being cholangiocarcinoma. It has an insidious presentation, which is responsible for the delayed presentation. Hence, the management strategy relies on screening to diagnose it an early stage for curative resection and/or treatment with local ablative techniques or chemotherapy. However, even with different screening programs, more than 60% of tumors are still detected at an advanced stage, leading to an unchanged mortality rate, thereby implying a room for improvement in the screening and diagnostic process. In the last few years, there has been evolution of utility of endoscopy, specifically endoscopic ultrasonography along with Fine needle aspiration, for this purpose, which we comprehensively review in this article. PMID- 29467917 TI - Preliminary study of automatic gastric cancer risk classification from photofluorography. AB - AIM: To perform automatic gastric cancer risk classification using photofluorography for realizing effective mass screening as a preliminary study. METHODS: We used data for 2100 subjects including X-ray images, pepsinogen I and II levels, PGI/PGII ratio, Helicobacter pylori (H. pylori) antibody, H. pylori eradication history and interview sheets. We performed two-stage classification with our system. In the first stage, H. pylori infection status classification was performed, and H. pylori-infected subjects were automatically detected. In the second stage, we performed atrophic level classification to validate the effectiveness of our system. RESULTS: Sensitivity, specificity and Youden index (YI) of H. pylori infection status classification were 0.884, 0.895 and 0.779, respectively, in the first stage. In the second stage, sensitivity, specificity and YI of atrophic level classification for H. pylori-infected subjects were 0.777, 0.824 and 0.601, respectively. CONCLUSION: Although further improvements of the system are needed, experimental results indicated the effectiveness of machine learning techniques for estimation of gastric cancer risk. PMID- 29467918 TI - Preclinical assessment of galunisertib (LY2157299 monohydrate), a first-in-class transforming growth factor-beta receptor type I inhibitor. AB - Transforming growth factor-beta (TGFbeta) is an important driver of tumor growth via intrinsic and extrinsic mechanisms, and is therefore an attractive target for developing cancer therapeutics. Using preclinical models, we characterized the anti-tumor activity of a small molecule inhibitor of TGFbeta receptor I (TGFbetaRI), galunisertib (LY2157299 monohydrate). Galunisertib demonstrated potent and selective inhibition of TGFbetaRI with corresponding inhibition of downstream signaling via inhibition of SMAD phosphorylation (pSMAD). Galunisertib also inhibited TGFbeta-induced pSMAD in vivo, which enabled a pharmacokinetic/pharmacodynamic profile in Calu6 and EMT6-LM2 tumors. Galunisertib demonstrated anti-tumor activity including inhibition of tumor cell migration and mesenchymal phenotype, reversal of TGFbeta-mediated immune suppression, and tumor growth delay. A concentration-effect relationship was established with a dosing schedule to achieve the optimal level of target modulation. Finally, a rat model demonstrated a correlation between galunisertib dependent inhibition of pSMAD in tumor tissues and in PBMCs, supporting the use of PBMCs for assessing pharmacodynamic effects. Galunisertib has been tested in several clinical studies with evidence of anti-tumor activity observed in subsets of patients. Here, we demonstrate that galunisertib inhibits a number of TGFbeta dependent functions leading to anti-tumor activity. The enhanced understanding of galunisertib provides rationale for further informed clinical development of TGFbeta pathway inhibitors. PMID- 29467919 TI - Interleukin-13 peptide vaccine induces protective humoral immunity in murine asthma models. AB - This study presents a rational design approach to discovery synthetic peptide vaccine candidates from endogenous proteins for chronic non-infectious diseases immunological therapeutics. The approach described the screening of key antigenic amino acid residues of the interleukine-13, which is up-regulated expression in asthma, followed by the development of immunological helper epitope peptides via an integrative computational and experimental method. Notably, this totally synthetic peptide vaccine was capable of stimulating humoral immune responses much stronger than those of parental antigenic peptides by enhancing the efficiency of antigen presentation, and had effective treatment in mouse asthma models. Our approach offers new possibilities to discovery therapeutic peptide vaccine candidates for chronic non-infectious diseases, with highly consolidated in silico and animal disease models for fast iterative screening. PMID- 29467920 TI - Idiopathic multicentric Castleman's disease: a clinicopathologic study in comparison with IgG4-related disease. AB - The present study aimed to compare clinicopathologic features between idiopathic multicentric Castleman's disease (n=22) and IgG4-related disease (n=26). Histology was analyzed using lymph node and lung biopsies. The expression of IL-6 mRNA in tissue was also examined by in situ hybridization and real-time PCR. Patients with idiopathic multicentric Castleman's disease were significantly younger than those with IgG4-related disease (p<0.001). Splenomegaly was observed in only idiopathic multicentric Castleman's disease (p=0.002), while pancreatitis and sialo-dacryoadenitis were restricted to IgG4-related disease (both p<0.001). Serum IgG4 concentrations were commonly elevated at >135 mg/dL in both groups (p=0.270). However, the IgG4/IgG ratio in IgG4-related disease was significantly higher than that in Castleman's disease (p<0.001). Histologically, sheet-like plasmacytosis was highly characteristic of idiopathic multicentric Castleman's disease (p<0.001), while plasmacytic infiltration in IgG4-related disease was always associated with intervening lymphocytes. Similar to laboratory findings, the IgG4/IgG-positive plasma cell ratio, but not the IgG4-positive cell count, was significantly higher in IgG4-related disease (p=0.002). Amyloid-like hyalinized fibrosis was found in 6/8 lung biopsies (75%) of Castleman's disease. The over-expression of IL-6 mRNA was not confirmed in tissue samples of Castleman's disease by either in situ hybridization or quantitative real-time PCR. In conclusion, useful data for a differential diagnosis appear to be age, affected organs, the serum IgG4/IgG ratio, sheet-like plasmacytosis in biopsies, and the IgG4/IgG-positive cell ratio on immunostaining. Since IL-6 was not over expressed in tissue of idiopathic multicentric Castleman's disease, IL-6 may be produced outside the affected organs, and circulating IL-6 may lead to lymphoplasmacytosis at nodal and extranodal sites.

AB - Disturbances in endoplasmic reticulum (ER) function lead to ER stress which, when severe or prolonged, may result in apoptosis. Severe ER stress has been implicated in several pathological conditions including pre-eclampsia, a multisystem disorder of pregnancy associated with the release of pro-inflammatory factors from the placenta into the maternal circulation. Here, we show that severe ER stress induced by two distinct mechanisms in BeWo choriocarcinoma cells leads to the release of extracellular vesicles (EVs) carrying pro-inflammatory damage-associated molecular pattern (DAMP) molecules. Co-treatment with the antioxidant pyrrolidine dithiocarbamate results in a reduction in ER stress induced EV-associated DAMP release. We further demonstrate that severe ER stress is associated with changes in the expression of several stress-related proteins, notably Cited-2 and phosphorylated JNK. Together, these data indicate that severe ER stress-mediated release of EV-associated DAMPs may contribute to the heightened systemic maternal inflammatory response characteristic of pre eclampsia and may also be relevant to other chronic inflammatory diseases which display elevated ER stress.

AB - Facing the challenge of effective prevention type 2 diabetes (T2DM) in China (as part of global health) requires knowledge about both the temporal trend and risk factors variation in T2DM. We searched the PubMed, CNKI, WANFANG, and International Diabetes Federation (IDF) databases for data on the prevalence of T2DM/ IGT (impaired glucose tolerance) published from January 1, 1980 to December 31, 2014 in China, Japan and Korea. The prevalence of T2DM was estimated with 95% confidence intervals (CIs) using random-effects meta-analysis. T2DM prevalence trend in the next 10 years was estimated by using a time series regression model based on the 35 years of data. The 621 articles covered 11.8 million Chinese people, 1.64 million Japanese, and 37.69 million Koreans. The aggregate prevalence of T2DM in China has increased sharply from 1.3% in 1980-1989 to 4.5% in 1990-1999, 6.8% 2000-2009, and 8.7% in 2010-2014. We estimated that by 2025, T2DM prevalence will have grown to 12.5%. Central obesity is the largest preventable cause of T2DM. We also found that female having a very high BMI (body mass index, >=28 kg/m2) and being an older (>=50 years old) female are next highest risk factors for T2DM compared with male. Consistent with the patterns characterized for China, T2DM prevalence in Japan increased with aging, and men were more likely to develop T2DM. It was the same as Korea. In the Far East, especially in China, T2DM prevalence will continue to increase until 2025. Statistical analyses were conducted using Stata 12.0 and SPSS 19.0. PMID- 29467923 TI - Synthetic analysis of associations between IL-10 polymorphisms and skin cancer risk. AB - The current study was designed to quantitatively summarize the evidence for the strength of the associations between common IL-10 functional polymorphisms and skin cancer risk. Relevant publications concerning the associations between common IL-10 functional polymorphisms(-1082G>A, -819C>T and -592C>A) and skin cancer were retrieved by a comprehensive electronic literature search in PubMed, Web of Science, EBSCO, Embase, China National Knowledge Infrastructure, Wanfang, Chinese Biomedical Database (CBM). The odds ratio (OR) and 95% confidence interval (CI) were utilized to assess the strength of the relationship. A total of 26 studies including 4090 cases and 4133 controls (-1082G>A, 10 studies with 1809 cases and 1830 controls; -819C>T, 7 studies with 862 cases and 957 controls; -592C>A, 9 studies with 1419 cases and 1346 controls) were enrolled in the meta analysis. Overall, the results revealed a borderline decreased risk of skin cancer in heterozygote model (OR = 0.82, 95CI = 0.67-1.00, p = 0.05). The subgroup analysis also presented similar association for non-melanoma skin cancer in heterozygote model (OR = 0.67, 95CI = 0.50-0.91, p = 0.01). Moreover, the further analysis based on the histological type of non-melanoma skin cancer indicated a significantly decreased risk of BCC in allele model (OR = 0.67, 95% CI = 0.50-0.91, p = 0.02) and dominant model (OR = 0.68, 95% CI = 0.48-0.98, p = 0.04). However, neither overall analysis nor subgroup analysis based on cancer subtype revealed a significant association of -1082G>A or -592C>A polymorphisms with skin cancer. The present study suggested a potential association between IL 10 -819C>T polymorphism and decreased risk of skin cancer, but a lack of association for -1082G>A and -592C>A polymorphisms. Further invalidation is urgently needed. PMID- 29467924 TI - Prognostic significance of Cytokeratin 20-positive lymph node vascular endothelial growth factor A mRNA and chromodomain helicase DNA binding protein 4 in pN0 colorectal cancer patients. AB - BACKGROUND: Cytokeratin 20-positive cells in lymph nodes from pN0 colorectal cancer (CRC) patients were detected previously by us. The aims of this study were to investigate which tumor metastasis-related genes were involved and their potential clinical significance. RESULTS: Fourteen of 84 (17%) genes were differentially expressed by at least 2-fold. Among them, 10 genes were up regulated whereas 4 genes were down-regulated. Those differential expressed genes were validated in the second cohort of specimens. Follow-up analysis for 60 months showed that patients with lymph node vascular endothelial growth factor A (VEGF-A) mRNA and chromodomain helicase DNA binding protein 4 (CHD4) mRNA expression higher than the median copies had significantly shorter time to recurrence than those with lower than the median copies. Multivariate analysis showed that VEGF-A mRNA, CHD4 mRNA and lymphatic vessel involvement were independent prognostic factors for disease recurrence. CONCLUSIONS: VEGF-A mRNA and CHD4 mRNA were up-regulated in CK20-positive pN0 lymph nodes and they may have prognostic significance in pN0 CRC patients. METHODS: Two cohorts of lymph node specimens from pN0 CRC patients of each with and without CK20-positive cells were recruited. In the first cohort, tumor metastasis genes were profiled using gene expression arrays. Differential expressed genes were validated in the second cohort. Moreover, their prognostic significance was examined by following-up the second cohort of patients with CK20-positive cells for 60 months and all histopathological findings were correlated to recurrence. PMID- 29467925 TI - Plasma YKL-40 as a biomarker for bevacizumab efficacy in patients with newly diagnosed glioblastoma in the phase 3 randomized AVAglio trial. AB - YKL-40 is a glycoprotein with pro-angiogenic functions. We hypothesized that patients with newly diagnosed glioblastoma and low baseline plasma YKL-40 levels derive greater benefit from first-line bevacizumab. Plasma samples were collected from 563 patients in the randomized, phase 3 AVAglio trial who received bevacizumab or placebo plus radiotherapy/temozolomide. Raw plasma YKL-40 concentrations were converted to age-corrected percentiles of normal healthy YKL 40 levels and divided into quartiles (Q). The impact of baseline plasma YKL-40 level on survival was investigated using Cox regression analyses. Patients with low baseline plasma YKL-40 (<=Q1) had an improved progression-free survival hazard ratio (HR) for bevacizumab versus placebo (0.37, 95% confidence interval [CI]: 0.25-0.55) compared with high plasma YKL-40 (> Q1) (0.71, 95% CI: 0.57 0.87). Overall survival HRs were comparable between the subgroups (<= Q1: 0.69, 95% CI: 0.44-1.09; (> Q1: 0.88, 95% CI: 0.68-1.13). A trend for improved progression-free survival HR with low versus high YKL-40 was observed in proneural glioblastoma (0.41, 95% CI: 0.13-1.28 vs 0.80, 95% CI: 0.45-1.40, respectively), but not for proliferative/mesenchymal subtypes. Elevated plasma YKL-40 (> 90th percentile of normal) was an independent negative prognostic factor. In conclusion, the predictive value of baseline plasma YKL-40 level as a biomarker for bevacizumab efficacy in glioblastoma may be limited to patients with proneural tumors. Independent validation studies are required to confirm these results. PMID- 29467926 TI - Distinct pattern of cerebral blood flow alterations specific to schizophrenics experiencing auditory verbal hallucinations with and without insight: a pilot study. AB - Schizophrenia is associated with widespread and complex cerebral blood flow (CBF) disturbance. Auditory verbal hallucinations (AVH) and insight are the core symptoms of schizophrenia. However, to the best of our knowledge, very few studies have assessed the CBF characteristics of the AVH suffered by schizophrenic patients with and without insight. Based on our previous findings, Using a 3D pseudo-continuous ASL (pcASL) technique, we investigated the differences in AVH-related CBF alterations in schizophrenia patients with and without insight. We used statistical parametric mapping (SPM8) and statistical non-parametric mapping (SnPM13) to perform the fMRI analysis. We found that AVH schizophrenia patients without insight showed an increased CBF in the left temporal pole and a decreased CBF in the right middle frontal gyrus when compared to AVH-schizophrenia patients with insight. Our novel findings suggest that AVH schizophrenia patients without insight possess a more complex CBF disturbance. Simultaneously, our findings also incline to support the idea that the CBF aberrant in some specific brain regions may be the common neural basis of insight and AVH. Our findings support the mostly current hypotheses regarding AVH to some extent. Although our findings come from a small sample, it provide the evidence that indicate us to conduct a larger study to thoroughly explore the mechanisms of schizophrenia, especially the core symptoms of AVHs and insight. PMID- 29467927 TI - Kanglaite inhibits EMT caused by TNF-alpha via NF-kappaBeta inhibition in colorectal cancer cells. AB - Tumor necrosis factor-alpha is a critical pro-inflammatory cytokine produced by macrophages and was once considered an anti-tumor agent. However, a low dose of tumor necrosis factor-alpha can cause epithelial mesenchymal transition, angiogenesis and metastasis. NF-kappaBeta contributes to epithelial mesenchymal transition induced by tumor necrosis factor-alpha. Kanglaite, an extract from the Coix lacryma-jobi (adlay) seed, is an NF-kappaBeta inhibitor. The aim of this study was to investigate whether Kanglaite could inhibit epithelial mesenchymal transition caused by tumor necrosis factor-alpha using four colorectal cancer cell lines, HCT106, HCT116, LoVo and CT26. Our results showed that tumor necrosis factor-alpha -mediated activation of NF-kappaBeta, caused changes in epithelial mesenchymal transition -related protein expression, and increased migration and invasion in all four cell lines. However, these effects were inhibited by Kanglaite when used in combination with tumor necrosis factor-alpha. In a subcutaneous tumor model of CT26, tumor necrosis factor-alpha enhanced the tumorigenic ability of the cells, and again this was inhibited by Kanglaite. However, treatment with Kanglaite alone caused almost no inhibition of epithelial mesenchymal transition -mediated tumor growth, when cells were pretreated with tumor necrosis factor-alpha prior to injection. These results suggest that Kanglaite inhibits tumor necrosis factor-alpha -mediated epithelial mesenchymal transition in colorectal cancer cell lines via inhibition of NF-kappaBeta. PMID- 29467928 TI - Inferring modes of evolution from colorectal cancer with residual polyp of origin. AB - Besides the classical evolutionary model of colorectal cancer (CRC) defined by the stepwise accumulation of mutations in which normal epithelium transforms through an intermediary polyp stage to cancer, a few studies have proposed alternative modes of evolution (MOE): early eruptive subclonal expansion, branching of the subclones in parallel evolution, and neutral evolution. However, frequencies of MOEs and their connection to mutational characteristics of cancer remain elusive. In this study, we analyzed patterns of somatic single nucleotide variations (SNVs) and copy number aberrations (CNAs) in CRC with residual polyp of origin from 13 patients in order to determine this relationship. For each MOE we defined an expected pattern with characteristic features of allele frequency distributions for SNVs in cancers and their matching adenomas. From these distinct patterns, we then assigned an MOE to each CRC case and found that stepwise progression was the most common (70% of cases). We found that CRC with the same MOE may exhibit different mutational spectra, suggesting that different mutational mechanisms can result in the same MOE. Inversely, cancers with different MOEs can have the same mutational spectrum, suggesting that the same mutational mechanism can lead to different MOEs. The types of somatic substitutions, distribution of CNAs across genome, and mutated pathways did not correlate with MOEs. As this could be due to small sample size, these relations warrant further investigation. Our study paves the way to connect MOE with clinical and mutational characteristics not only in CRC but also to neoplastic transformation in other cancers. PMID- 29467929 TI - The SNPs in pre-miRNA are related to the response of capecitabine-based therapy in advanced colon cancer patients. AB - The single nucleotide polymorphisms (SNPs) in the microRNA precursor (pre-miRNA) may modulate the posttranscriptional regulation of gene expression and explain individual sensitivity to chemotherapy. Here we investigated the correlation between 23 SNPs in the pre-miRNA and the efficacy of capecitabine-based chemotherapy in 274 advanced colon cancer patients. Statistical analysis indicated that much more patients with rs744591 A/C(48.03%), C/C (53.45%) or C allele (49.73%) responded to the chemotherapy than those with the A/A genotype (33.71%). The response rates of rs745666 G/C heterozygous patients (35.25%) and C allele carriers (39.69%) were apparently less than that of the G/G homozygous patients (56.25%). Moreover, three SNPs rs2114358, rs35770269, and rs73239138 were significantly associated with the occurrence of side effects of chemotherapy. The patients with rs2114358 C allele (OR = 2.016) or rs35770269 T allele (OR = 2.299) were much more prone to endure adverse events. However, the incidence of side effect was lower in the patients carrying rs73239138 A allele than those with G/G genotype (OR = 0.500). Our findings demonstrate that genetic variations in pre-miRNA may influence the efficacy of capecitabine-based chemotherapy in advanced colon cancer patients. PMID- 29467930 TI - Identification of the potential crucial genes in invasive ductal carcinoma using bioinformatics analysis. AB - Invasive ductal carcinoma (IDC) is a common histological type of breast cancer. The aim of this study was to identify the potential crucial genes associated with IDC and to provide valid biological information for further investigations. The gene expression profiles of GSE10780 which contained 42 histologically normal breast tissues and 143 IDC tissues were downloaded from the GEO database. Functional and pathway enrichment analysis of differentially expressed genes (DEGs) were performed and protein-protein interaction (PPI) network was analyzed using Cytoscape. In total, 999 DEGs were identified, including 667 up-regulated and 332 down-regulated DEGs. Gene ontology analysis demonstrated that most DEGs were significantly enriched in mitotic cell cycle, adhesion and protein binding process. Through PPI network analysis, a significant module was screened out, and the top 10 hub genes, CDK1, CCNB1, CENPE, CENPA, PLK1, CDC20, MAD2L1, HIST1H2BK, KIF2C and CCNA2 were identified from the PPI network. The expression levels of the 10 genes were validated in Oncomine database. KIF2C, MAD2L1 and PLK1 were associated with the overall survival. And we used cBioPortal to explore the genetic alterations of hub genes and potential drugs. In conclusion, the present study identified DEGs between normal and IDC samples, which could improve our understanding of the molecular mechanisms in the development of IDC, and these candidate genes might be used as therapeutic targets for IDC. PMID- 29467931 TI - Toll-like receptor 2 induces adenosine receptor A2a and promotes human squamous carcinoma cell growth via extracellular signal regulated kinases 1/2. AB - Patient treatment for oral squamous cell carcinoma (OSCC) not associated with Human papillomavirus remains problematic. OSCC microenvironment is typically inflamed and colonized by microorganisms, providing ligands for toll-like receptors (TLR). In immune cells TLR2 and TLR4 activate NF-kB and extracellular signal regulated kinase (ERK)1/2 pathways, leading to upregulation of inhibitory adenosine receptors A2a and A2b, and reduction in stimulatory A1 and A3. How TLR and adenosine receptors function in SCC cells is not understood. To address this gap, we evaluated TLR and adenosine receptor expression and function in human OSCC cells and keratinocytes. TLR2 and A2a were co-expressed in pre-cancer and SCC cells of 17 oral specimens. In vitro, 5/6 OSCC lines expressed more TLR2 than TLR1, 4 or 6 mRNA. TLR2 ligands stimulated A2a expression in TLR2-high cell lines, but no A1 or A3 was detected with or without stimuli. In TLR2-high OSCC, TLR2/1, 2/6 and adenosine receptor agonists activated ERK1/2. TLR2-mediated ERK1/2 phosphorylation resulted in accumulation of c-FOS, ERK-dependent cell proliferation and reduced caspase-3 activity. Similar ERK1/2-dependent proliferation and decreased caspase-3 activity were caused by combined TLR2 and adenosine receptor stimuli. We conclude that TLR2 and adenosine receptor agonists, known to be present in the tumor microenvironment, may contribute to OSCC progression in part via direct effects on the ERK1/2 pathway in squamous carcinoma cells. PMID- 29467932 TI - Characterization of aptamer-mediated gene delivery system for liver cancer therapy. AB - Liver cancer is a fatal disease with limited therapy options. The recombinant adenovirus expressing tumor-suppressor gene of PTEN (Ad5-PTEN) showed effective antitumor activity against liver cancer. However, its disadvantages produced great limitation on its application, especially its nonspecific and toxicity to normal cells and tissues. The epithelial cell adhesion molecule (EpCAM) is over expressed in some liver cancer cells and an RNA aptamer EpDT3 could specially target to EpCAM-positive cells. Based on this founding, we aimed to design a kind of gene delivery system of EpDT3-mediated Ad5-PTEN (EpDT3-PEG-Ad5-PTEN, EPAP) in which polyethylene glycol was used to be a linker to conjugate EpDT3 with Ad5 PTEN. This strategy may overcome the disadvantages of naked Ad5-PTEN and enhance the antitumor effect on liver cancer. The SDS-PAGE electrophoresis, TBE-PAGE electrophoresis and fluorescence detection were conducted to confirm the successful preparation of EPAP. Compared with the naked Ad5-PTEN, EPAP showed significant anti-proliferative and anti-migratory activities against HepG2 cells. EPAP also showed selective and precise target ability to EpCAM-positive HepG2 cells in vivo. Therefore, EPAP may be further explored as a novel effective anticancer drug for malignant liver cancer. PMID- 29467933 TI - Determinants of variability of five programmed death ligand-1 immunohistochemistry assays in non-small cell lung cancer samples. AB - Programmed death ligand-1 (PD-L1) expression as determined by immunohistochemistry (IHC) is potentially predictive of clinical outcome. The aim of this study was to assess the concordance of reported PD-L1 IHC assays and investigate factors influencing variability. Consecutive sections from 20 non small cell lung cancers (NSCLCs) comprising resection, core biopsy, cytology and pleural fluid samples underwent IHC with 5 different antibody/autostainer combinations: 22C3/Link48, 28-8/BOND-MAX, E1L3N/BOND-MAX, SP142/BenchMark and SP263/BenchMark. PD-L1 RNA levels were assessed using RNAscope. The frequency of positive cases using scoring thresholds from clinical trials was 72%, 33%, 61%, 56%, and 33% for the 5 IHC protocols respectively, and 33% for RNAscope. Pairwise agreement on the classification of cases as positive or negative for PD-L1 expression ranged from 61%-94%. On a continuous scale, the lowest correlation was between 28-8/BOND-MAX and SP142/BenchMark (R2=0.25) and highest was between 22C3/Link48 and E1L3N/BOND-MAX (R2=0.71). When cases were ordered according to tumor cell (TC)%, a similar ranking of cases across IHC protocols could be observed, albeit with different quanta and limits of detection. Single-slide OPAL 7-color fluorescence IHC analysis revealed a high degree of co-localization of staining from the 5 PD-L1 antibodies. Using SP142 antibody in a BOND-MAX protocol led to increased TC% quanta, while retaining a similar ranking of samples according to TC%. The results of this study highlight tumor PD-L1 status can vary significantly according to IHC protocol. Protocol-dependent staining intensities and nominated thresholds for positivity contribute to this variability, while the antibody used appears to be less of a factor. PMID- 29467934 TI - Effects of STC1 overexpression on tumorigenicity and metabolism of hepatocellular carcinoma. AB - Stanniocalcin-1 (STC1) is a paracrine factor associated with inflammation and carcinogenesis. Using clinicopathological data, we previously reported that a greater expression of STC1 in hepatocellular carcinoma (HCC) was significantly correlated with smaller tumor size. The underlying mechanism on the correlation is not known. In this study, using a metastatic HCC cell-line (MHCC-97L, P) and lentiviral vector mediated-STC1 overexpression, the inoculation of STC1 overexpressing MHCC-97L (S1) cells in a nude mice xenograft model demonstrated reductions in tumor mass and volume. As compared with P cells, S1 cells exhibited epithelial phenotype with significantly lower plating efficiency and reduced migratory and proliferative potential. Using coulter counter for cell-sizing, S1 cells (17.6 MUm) were significantly smaller than P cells (19.6 MUm). Western blot analysis revealed that S1 cells exhibited reduced expression level of phosphorylated ribosomal protein S6 (p-rpS6). Moreover, an inhibition of the upstream kinase p70S6K was evident with the dephosphorylation of Thr389 in the linker domain of the kinase. The inhibition of p70S6K/p-rpS6 pathway was accompanied with reduced cellular ATP level and increase of p-AMPK in S1 cells. Significantly lower rates of glycolysis and extracellular O2 consumption in S1 cells exhibited a lower cellular energy status. Since a faster rate of ATP production is essential to support cancer growth and metastasis, the present study identified the effect of STC1-overexpression on reducing energy metabolism, leading to an activation of AMPK pathway but an inhibition of p70S6K/p-rpS6 signaling to reduce tumor growth. PMID- 29467935 TI - A robust gene expression-based prognostic risk score predicts overall survival of lung adenocarcinoma patients. AB - Identification of reliable predictive biomarkers and new therapeutic targets is a critical step for significant improvement in patient outcomes. Here, we developed a multi-step bioinformatics analytic strategy to mine large omics and clinical data to build a prognostic scoring system for predicting the overall survival (OS) of lung adenocarcinoma (LuADC) patients. In latter we first identified 1327 significantly and robustly deregulated genes, 600 of which were significantly associated with the OS of LuADC patients. Gene co-expression network analysis revealed the biological functions of these 600 genes in normal lung and LuADCs, which were found to be enriched for cell cycle-related processes, blood vessel development, cell-matrix adhesion and metabolic processes. Finally, we implemented a multiple resampling method combined with Cox regression analysis to identify a 27-gene signature associated with OS, and then created a prognostic scoring system based on this signature. This scoring system robustly predicted OS of LuADC patients in 100 sampling test sets and was further validated in four independent LuADC cohorts. In addition, in comparison to other existing prognostic gene signatures published in the literature, our signature was significantly superior in predicting OS of LuADC patients. In summary, our multi omics and clinical data integration study created a 27-gene prognostic risk score that can predict OS of LuADC patients independent of age, gender and clinical stage. This score could guide therapeutic selection and allow stratification in clinical trials. PMID- 29467936 TI - Dynamic changes in CD44v-positive cells after preoperative anti-HER2 therapy and its correlation with pathologic complete response in HER2-positive breast cancer. AB - Chemotherapy has been reported to increase the proportion of cancer stem cells (CSCs) and to promote epithelial-mesenchymal transition (EMT) phenotype changes. Anti-HER2 therapy may provide a strategy for eliminating CSC and EMT, which contribute to therapeutic resistance. No study has determined the changes in the quantity or characteristics of CSCs or circulating tumor cells (CTCs) with EMT phenotype during preoperative anti-HER2 therapy, and whether these changes correlate to response to dual anti-HER2 therapy. In a prospective clinical trial to evaluate pharmacodynamic biomarkers, 18 patients with operable primary HER2 positive breast cancer received dual anti-Her2 preoperative therapy with trastuzumab and lapatinib with paclitaxel. Proportions of tumor cells with CSC characteristics and EMT markers in CTC's were estimated at baseline, after 6 and 18 weeks of preoperative therapy to determine the quantitative cutoff value to predict pathologic complete response (pCR). Out of 18 patients, 8 (44%) had a pCR; 5 of these 8 patients (62%) were positive for CD44v at baseline and none were positive on the 6-week biopsy. In contrast, 6 of the 10 patients without pCR exhibited persistent levels, or enrichment of CD44v proportion and expression at 6 and 18 weeks (p=0.0128). Other biomarkers were not statistically significant predictors of pCR. Enrichment of CD44v-positive tumor cells after dual anti-HER2 therapy alone may predict poor response to dual anti-HER2 therapy plus chemotherapy. PMID- 29467937 TI - Temozolomide, sirolimus and chloroquine is a new therapeutic combination that synergizes to disrupt lysosomal function and cholesterol homeostasis in GBM cells. AB - Glioblastoma (GBM) cells are characterized by high phagocytosis, lipogenesis, exocytosis activities, low autophagy capacity and high lysosomal demand are necessary for survival and invasion. The lysosome stands at the cross roads of lipid biosynthesis, transporting, sorting between exogenous and endogenous cholesterol. We hypothesized that three already approved drugs, the autophagy inducer, sirolimus (rapamycin, Rapa), the autophagy inhibitor, chloroquine (CQ), and DNA alkylating chemotherapy, temozolomide (TMZ) could synergize against GBM. This repurposed triple therapy combination induced GBM apoptosis in vitro and inhibited GBM xenograft growth in vivo. Cytotoxicity is caused by induction of lysosomal membrane permeabilization and release of hydrolases, and may be rescued by cholesterol supplementation. Triple treatment inhibits lysosomal function, prevents cholesterol extraction from low density lipoprotein (LDL), and causes clumping of lysosome associated membrane protein-1 (LAMP-1) and lipid droplets (LD) accumulation. Co-treatment of the cell lines with inhibitor of caspases and cathepsin B only partially reverse of cytotoxicities, while N-acetyl cysteine (NAC) can be more effective. A combination of reactive oxygen species (ROS) generation from cholesterol depletion are the early event of underling mechanism. Cholesterol repletion abolished the ROS production and reversed the cytotoxicity from QRT treatment. The shortage of free cholesterol destabilizes lysosomal membranes converting aborted autophagy to apoptosis through either direct mitochondria damage or cathepsin B release. This promising anti-GBM triple therapy combination severely decreases mitochondrial function, induces lysosome dependent apoptotic cell death, and is now poised for further clinical testing and validation. PMID- 29467938 TI - SMAD4-independent activation of TGF-beta signaling by MUC1 in a human pancreatic cancer cell line. AB - Pancreatic Ductal Adenocarcinoma (PDA) has a mortality rate that nearly matches its incidence rate. Transforming Growth Factor Beta (TGF-beta) is a cytokine with a dual role in tumor development switching from a tumor suppressor to a tumor promoter. There is limited knowledge of how TGF-beta function switches during tumorigenesis. Mucin 1 (MUC1) is an aberrantly glycosylated, membrane-bound, glycoprotein that is overexpressed in >80% of PDA cases and is associated with poor prognosis. In PDA, MUC1 promotes tumor progression and metastasis via signaling through its cytoplasmic tail (MUC1-CT) and interacting with other oncogenic signaling molecules. We hypothesize that high levels of MUC1 in PDA may be partly responsible for the TGF-beta functional switch during oncogenesis. We report that overexpression of MUC1 in BxPC3 human PDA cells (BxPC3.MUC1) enhances the induction of epithelial to mesenchymal transition leading to increased invasiveness in response to exogenous TGF-beta1. Simultaneously, these cells resist TGF-beta induced apoptosis by downregulating levels of cleaved caspases. We show that mutating the tyrosines in MUC1-CT to phenylalanine reverses the TGF beta induced invasiveness. This suggests that the tyrosine residues in MUC1-CT are required for TGF-beta induced invasion. Some of these tyrosines are phosphorylated by the tyrosine kinase c-Src. Thus, treatment of BxPC3.MUC1 cells with a c-Src inhibitor (PP2) significantly reduces TGF-beta induced invasiveness. Similar observations were confirmed in the Chinese hamster ovarian (CHO) cell line. Data strongly suggests that MUC1 may regulate TGF-beta function in PDA cells and thus have potential clinical relevance in the use of TGF-beta inhibitors in clinical trials. PMID- 29467939 TI - Socioeconomic status is inversely associated with esophageal squamous cell carcinoma risk: results from a population-based case-control study in China. AB - Socioeconomic status (SES) is suspected to influence the risk of esophageal squamous-cell carcinoma (ESCC) in China, however, the evidence is still inconclusive and the selection of SES indicators remains inconsistent. In current study, we examined the association between SES and risk of ESCC based on a population-based case-control study in Taixing, China, with 1298 histopathology confirmed cases and 1900 controls recruited between October 2010 and September 2013. Data on SES indicators was collected using a structured questionnaire. We constructed a composite wealth score based on the ownership of a series of household appliances and other variables by using multiple correspondence analysis (MCA). We used unconditional logistic regression to estimate odds ratios (ORs) with 95% confidence intervals (CIs) of ESCC in association with SES indicators. SES was inversely associated with ESCC risk in current study. Higher education (secondary high school or above vs illiteracy, OR=0.60, 95%CI, 0.41 0.87), larger house area per person (>70 vs <45 square meters, OR=0.71, 95%CI, 0.59-0.86) and higher wealth score (5th quintile (high) vs 1st quintile (low), OR=0.43, 95%CI, 0.32-0.57) were associated with a decreased risk of ESCC. Subjects possessing several household appliances >5 years also had a lower ESCC risk. Whereas physical labor (very active vs sedentary, OR=1.69, 95%CI, 1.27 2.26) and larger families (>=6 vs <3 in household, OR=1.63, 95%CI, 1.30-2.03) increased the risk of ESCC. These findings confirm the strong inverse association between SES and ESCC risk. Future studies are needed to verify these findings and identify contributing factors underlying the observed associations. PMID- 29467940 TI - ZB716, a steroidal selective estrogen receptor degrader (SERD), is orally efficacious in blocking tumor growth in mouse xenograft models. AB - Advances in oral SERDs development so far have been confined to nonsteroidal molecules such as those containing a cinnamic acid moiety, which are in earlystage clinical evaluation. ZB716 was previously reported as an orally bioavailable SERD structurally analogous to fulvestrant. In this study, we examined the binding details of ZB716 to the estrogen receptor alpha (ERalpha) by computer modeling to reveal its interactions with the ligand binding domain as a steroidal molecule. We also found that ZB716 modulates ERalpha-coregulator interactions in nearly identical manner to fulvestrant. The ability of ZB716 to inhibit cell growth and downregulate ER expression in endocrine resistant, ERalpha mutant breast cancer cells was demonstrated. Moreover, in both the MCF-7 xenograft and a patient derived xenograft model, orally administered ZB716 showed superior efficacy in blocking tumor growth when compared to fulvestrant. Importantly, such enhanced efficacy of ZB716 was shown to be attributable to its markedly higher bioavailability, as evidenced in the final plasma and tumor tissue concentrations of ZB716 in mice where drug concentrations were found significantly higher than in the fulvestrant treatment group. PMID- 29467941 TI - Spiclomazine displays a preferential anti-tumor activity in mutant KRas-driven pancreatic cancer. AB - Ras-targeted therapy represents a 'holy grail' in oncology. Based on our model prediction, Spiclomazine freezing the intermediate conformation of activated Ras is central to cancer therapeutics. We show here that Spiclomazine leads to an effective suppression in Ras-mediated signaling through abrogating the KRas-GTP level in the KRas-driven pancreatic cancer. The Ras-mediated signaling inhibition leads to dramatically reduced survivals of five KRas-driven pancreatic cancer cell lines with IC50 ranging 19.7~74.2 MUM after 48 hours of treatment. However, no significant changes have been observed for normal cell lines. It is worth mentioning that the mutant KRas-driven cancer cells are more sensitive towards Spiclomazine than the wild-type KRas cancer cells. Subsequent cellular thermal shift and RNA interference assays show that Spiclomazine efficiently binds with and stabilizes KRas to a certain extent within the cells. This validates the effect of target engagement on drug efficacy. Furthermore, Spiclomazine arrests cell cycle at G2 phase in the cancer cells, without obvious cell-cycle arrest in the normal cells. This further demonstrates its selectively biological response to cancer cells involved in Ras-GTP-mediated target engagement. Spiclomazine completely inhibits the growth of MIA PaCa-2 tumors on renal capsule xenograft models in BALB/c mice administered 68 mg kg-1 for 2 weeks via intra-peritoneal route. Immunohistochemical analyses reveal the reduced c-Raf and p-ERK and the increase in TUNEL staining. These observations further confirm the in vitro findings. Taken together, Spiclomazine is a selective inhibitor for mutant KRas driven pancreatic cancer. PMID- 29467942 TI - In vitro, in vivo and ex vivo demonstration of the antitumoral role of hypocretin 1/orexin-A and almorexant in pancreatic ductal adenocarcinoma. AB - Pancreatic ductal adenocarcinoma (PDAC) is still the poorest prognostic tumor of the digestive system. We investigated the antitumoral role of orexin-A and almorexant in PDAC. We analyzed the orexin receptor type 1 (OX1R) expression by immunohistochemistry in human normal pancreas, PDAC and its precursor dysplastic intraepithelial lesions. We used PDAC-derived cell lines and fresh tissue slices to study the apoptotic role of hypocretin-1/orexin-A and almorexant in vitro and ex vivo. We analyzed in vivo the hypocretin-1/orexin-A and almorexant effect on tumor growth in mice xenografted with PDAC cell lines expressing, or not, OX1R. Ninety-six percent of PDAC expressed OX1R, while adjacent normal exocrine pancreas did not. OX1R was expressed in pre-cancerous lesions. In vitro, under hypocretin-1/orexin-A and almorexant, the OX1R-positive AsPC-1 cells underwent apoptosis, abolished by the tyrosine phosphatase SHP2 inhibitor, NSC-87877, whereas the OX1R-negative HPAF-II cell line did not. These effects were mediated by phosphorylation of OX1R and recruitment of SHP2. Ex vivo, caspase-3 positive tumor cells were significantly higher in fresh tumour slices treated 48h with hypocretin-1/orexin-A, as compared to control, whereas cellular proliferation, assessed by Ki-67 index, was not modified. In vivo, when AsPC-1 cells or patient derived cells were xenografted in nude mice, hypocretin-1/orexin-A or almorexant, administrated both starting the day of cell line inoculation or after tumoral development, strongly slowed tumor growth. Hypocretin-1/orexin-A and almorexant induce, through OX1R, the inhibition of PDAC cellular growth by apoptosis. Hypocretins/orexins and almorexant might be powerful candidates for the treatment of PDAC. PMID- 29467943 TI - The modified glasgow prognostic score is an independent prognostic indicator in neoadjuvantly treated adenocarcinoma of the esophagogastric junction. AB - The modified Glasgow Prognostic Score (mGPS) combines the indicators of decreased plasma albumin and elevated CRP. In a number of malignancies, elevated mGPS is associated with poor survival. Aim of this study was to investigate the prognostic role of mGPS in patients with neoadjuvantly treated adenocarcinomas of the esophagogastric junction 256 patients from a prospective database undergoing surgical resection after neoadjuvant treatment between 2003 and 2014 were evaluated. mGPS was scored as 0, 1, or 2 based on CRP (>1.0 mg/dl) and albumin (<35 g/L) from blood samples taken prior (preNT-mGPS) and after (postNT-mGPS) neoadjuvant therapy. Scores were correlated with clinicopathological patients' characteristics. From 155 Patients, sufficient data was available. Median follow up was 63.8 months (33.3-89.5 months). In univariate analysis, Cox proportional hazard model shows significant shorter patients OS (p = 0.04) and DFS (p = 0.02) for increased postNT-mGPS, preNT-hypoalbuminemia (OS: p = 0.003; DFS: p = 0.002) and post-NT-CRP (OS: p = 0.03; DFS: p = 0.04). Elevated postNT-mGPS and preNT hypoalbuminemia remained significant prognostic factors in multivariate analysis for OS (p = 0.02; p = 0.005,) and DFS (p = 0.02, p = 0.004) with tumor differentiation and tumor staging as significant covariates. PostNT-mGPS and preNT-hypoalbuminemia are independent prognostic indicators in patients with neoadjuvantly treated adenocarcinomas of the esophagogastric junction and significantly associated with diminished OS and DFS. PMID- 29467944 TI - Distinct expression of CDCA3, CDCA5, and CDCA8 leads to shorter relapse free survival in breast cancer patient. AB - Breast cancer is a dangerous disease that results in high mortality rates for cancer patients. Many methods have been developed for the treatment and prevention of this disease. Determining the expression patterns of certain target genes in specific subtypes of breast cancer is important for developing new therapies for breast cancer. In the present study, we performed a holistic approach to screening the mRNA expression of six members of the cell division cycle-associated gene family (CDCA) with a focus on breast cancer using the Oncomine and The Cancer Cell Line Encyclopedia (CCLE) databases. Furthermore, Gene Expression-Based Outcome for Breast Cancer Online (GOBO) was also used to deeply mine the expression of each CDCA gene in clinical breast cancer tissue and breast cancer cell lines. Finally, the mRNA expression of the CDCA genes as related to breast cancer patient survival were analyzed using a Kaplan-Meier plot. CDCA3, CDCA5, and CDCA8 mRNA expression levels were significantly higher than the control sample in both clinical tumor sample and cancer cell lines. These highly expressed genes in the tumors of breast cancer patients dramatically reduced patient survival. The interaction network of CDCA3, CDCA5, and CDCA8 with their co-expressed genes also revealed that CDCA3 expression was highly correlated with cell cycle related genes such as CCNB2, CDC20, CDKN3, and CCNB1. CDCA5 expression was correlated with BUB1 and TRIP13, while CDCA8 expression was correlated with BUB1 and CCNB1. Altogether, these findings suggested CDCA3, CDCA5, and CDCA8 could have a high potency as targeted breast cancer therapies. PMID- 29467946 TI - The prognostic efficacy of cell-free DNA hypermethylation in colorectal cancer. AB - Epigenetic alterations in colorectal cancer (CRC) cause important differences in the underlying tumor biology and aggressiveness. DNA hypermethylation is central for the development of CRC but the prognostic impact remains elusive. We aimed to assess the association between cell-free hypermethylated DNA and stage and survival in colorectal cancer (CRC). We analyzed pre-treatment plasma samples from 193 patients with CRC. Thirty gene-promoter regions were analyzed using methylation specific PCR. We compared the median number (range) of hypermethylated promoter regions with CRC stage, and constructed a multivariable Cox-regression model adjusted for stage, to evaluate the added prognostic information. The median number of hypermethylated promoter regions was nine (0 28) in patients with distant metastasis compared to five (0-19) in patients without metastatic disease (p < 0.0001). The majority of the hypermethylated promoter regions inferred a poor prognosis. Cox-regression analysis adjusted for patient age, sex, pre-treatment CEA-levels, and disease stage, showed that RARB (HR = 1.99, 95% CI [1.07, 3.72]) and RASSF1A (HR = 3.35, 95% CI [1.76, 6.38]) hypermethylation inferred a significant effect on survival. The risk of metastasis increase with the number of cell-free hypermethylated promoter regions. The presence of RARB and RASSF1A hypermethylation indicated aggressive disease, regardless of stage at the time of diagnosis. PMID- 29467945 TI - A comparative study of PD-L1 immunohistochemical assays with four reliable antibodies in thymic carcinoma. AB - Currently, four immunohistochemical assays are registered with the US Food and Drug Administration to detect the expression of PD-L1. We investigated the PD-L1 expression in thymic carcinomas using these four diagnostic assays. The cases of 53 patients were reviewed and their specimens were subjected to four PD-L1 assays with different antibodies (SP142, SP263, 22C3, and 28-8). The PD-L1 expression in tumor cells (TCs) and immune cells (ICs) was evaluated. In TCs, the four assays showed similar scores in each case. Histopathologically, high TC scores were observed in squamous cell carcinomas (SqCCs). Meanwhile, there were no significant relationships among the IC scores in the four assays. In SqCCs, the high expression of PD-L1 (defined as >=50% TC score) in TCs tended to be associated with early stage cancer. The patients with high expression levels of PD-L1 tended to show longer overall survival in the 22C3 assays (p=0.0200). In thymic carcinomas, the staining pattern showed high concordance among the four assays when TCs - rather than ICs - were stained. High PD-L1 positivity in TCs, especially in SqCCs, indicated that PD-1/PD-L1 targeted therapy may be a promising therapeutic approach. PMID- 29467947 TI - Metformin inhibits TGF-beta1-induced epithelial-to-mesenchymal transition-like process and stem-like properties in GBM via AKT/mTOR/ZEB1 pathway. AB - Glioblastoma (GBM) is the most frequent and aggressive brain tumor in adults. In spite of advances in diagnosis and therapy, the prognosis is still relatively poor. The invasive property of GBM is the major cause of death in patients. Epithelial-to-mesenchymal transition-like process (EMT-like process) is considered to play an important role in the invasive property. Metformin has been reported as a regulator of EMT-like process. In this study, we confirmed that metformin inhibited TGF-beta1-induced EMT-like process and EMT-associated migration and invasion in LN18 and U87 GBM cells. Our results also showed that metformin significantly suppressed self-renewal capacity of glioblastoma stem cells (GSCs), and expression of stem cell markers Bmi1, Sox2 and Musashi1, indicating that metformin can inhibit cancer stem-like properties of GBM cells. We further clarified that metformin specifically inhibited TGF-beta1 activated AKT, the downstream molecular mTOR and the leading transcription factor ZEB1. Taken together, our data demonstrate that metformin inhibits TGF-beta1-induced EMT-like process and cancer stem-like properties in GBM cells via AKT/mTOR/ZEB1 pathway and provide evidence of metformin for further clinical investigation targeted GBM. PMID- 29467948 TI - Challenges in using liquid biopsies for gene expression profiling. AB - Circulating tumor cells (CTCs) have potential utility as a surrogate biomarker of tumor biology via a liquid biopsy. The aim of this study was to evaluate if the nCounter NanoString assay could be used for accurate gene expression profiling of CTCs using the PAM50 research-use-only CodeSet. Analysis was performed on CTCs isolated by the ANGLE Parsortix system from healthy blood spiked with the breast cancer cell lines Hs578T, SkBr3, MDA-MB-231 or MCF7. Using cell lines as gold standard positive controls and Parsortix processed blood without spiking (unspiked) as negative controls, we found an average of 12 significantly differentially expressed genes among spiked samples versus unspiked controls. We validated our findings with the NanoStringDiff differential expression statistical method. The NanoString recommended targeted pre-amplification introduced false positive results due to pre-amplification bias, and the amplification of non-cancer genes from normal leukocytes confounded gene expression profiling of CTCs. Pre-amplification bias is a concern for other similar assays that may be used as discovery tools or target validation of transcripts of interest in gene expression profiling of CTCs. We recommend the use of an unspiked negative control when evaluating CTC technologies regarding gene expression profiling. Given that the molecular profiling of CTCs as a liquid biopsy may have clinical ramifications for potential treatment selection in future clinical trials, our study emphasizes cautious consideration of pre analytical variables such as amplification bias in the context of liquid biopsy studies. PMID- 29467949 TI - Identification and characterisation of NANOG+/ OCT-4high/SOX2+ doxorubicin resistant stem-like cells from transformed trophoblastic cell lines. AB - Treatment of gestational trophoblastic diseases (GTD) involves surgery, radiotherapy and chemotherapy. Although, these therapeutic approaches are highly successful, drug resistance and toxicity remain a concern for high risk patients. This Chemoresistance has also been observed in the presence of cancer stem cells that are thought to be responsible for cases of cancer recurrence. In this study, we report the presence of previously unknown populations of trophoblastic stem like cells (SLCs) that are resistant to the chemotherapeutic drug doxorubicin. We demonstrate that these populations express the stem cell markers NANOG and Sox2 and higher levels of OCT-4 (NANOG+/OCT-4high/SOX2+). Although chemoresistant, we show that the invasive capacity of these trophoblastic SLCs is significantly inhibited by doxorubicin treatment. To better characterise these populations, we also identified cellular pathways that are involved in SLCs-chemoresistance to doxorubicin. In summary, we provide evidence of the presence of NANOG+/OCT 4+/SOX2+ trophoblastic SLCs that are capable to contribute to the susceptibility to GTD and that may be involved in Chemoresistance associated with drug resistance and recurrence in high risk GTDs' patients. We propose that targeting these populations could be therapeutically exploited for clinical benefit. PMID- 29467950 TI - Genetic polymorphisms in HLA-DP and STAT4 are associated with IgA nephropathy in a Southwest Chinese population. AB - IgA nephropathy (IgAN) is the most common chronic glomerular disease worldwide. Genetic factors are thought to be crucial in the pathogenesis of IgAN. However, few data are available on the relationship between human leucocyte antigen (HLA) and signal transducer and activator of transcription 4 (STAT4) polymorphisms and IgAN susceptibility in the Chinese population. Therefore, we examined HLA-DP/DQ and STAT4 polymorphisms (rs3077, rs9277535, rs7453920 and rs7574865) in a total of 630 subjects including 140 IgAN and 490 healthy controls in Chinese. There were significant associations between IgAN patients and healthy controls in the allele frequency of rs3077, rs9277535 and rs7574865. In addition, the genotypes of rs3077, rs9277535 and rs7574865 were also significantly associated with IgAN under recessive models. Moreover, the haplotypes block AAG, AGG, GAG and GGA in the HLA gene significantly correlated with the risk of IgAN. This is the first study demonstrating the significant associations of SNP rs3077, rs9277535 and rs7574865 and the haplotypes in the HLA gene with the risk of IgAN in a Southwest Chinese population. This research provides a new insight into the significant relationship between HLA-DP and STAT4 polymorphisms and the susceptibility to IgAN. PMID- 29467951 TI - Reverting iodine avidity of radioactive-iodine refractory thyroid cancer with a new tyrosine kinase inhibitor (K905-0266) excavated by high-throughput NIS (sodium iodide symporter) enhancer screening platform using dual reporter gene system. AB - Radioactive-iodine (RAI) therapy is typically unprevailing as anaplastic thyroid cancer (ATC) management, owing to the decrease in the endogenous sodium iodide symporter (NIS) expression. Therefore, new strategies for NIS re-induction are required to improve the efficacy of RAI therapy in ATC. In this study, we developed a novel high-throughput NIS enhancer screening platform using a dual reporter gene system to identify a potent tyrosine kinase inhibitor (TKI) and selected a new hit compound, K905-0266 TKI. The effects of K905-0266 TKI treatment was validated as RAI accumulation, changes in signalling pathway related to thyroid pathogenesis, and cytotoxicity of RAI depending on re induction of endogenous NIS expression in ATC. Furthermore, we evaluated enhancement of NIS promoter and therapeutic efficacy of RAI in ATC tumour xenograft mice. After K905-0266 TKI treatment, the expression of endogenous NIS was significantly increased, while phosphorylated-ERK was decreased. In addition, the thyroid-metabolising protein expressions were upregulated and increased of RAI accumulation and its therapeutic effects in ATC. Moreover, K905-0266 TKI increased therapeutic efficacy of RAI in ATC tumour in vivo. In conclusion, we successfully established a novel high-throughput NIS enhancer screening platform to excavate a NIS enhancer and identified K905-0266 TKI among TKI candidates and it's proven to increase the endogenous NIS expression and therapeutic efficacy of RAI in ATC. These findings suggest that a novel high-throughput NIS enhancer screening platform is useful for selecting of NIS promoter enhancers. In addition, K905-0266 TKI can be used to re-induce endogenous NIS expression and recover RAI therapy in ATC. PMID- 29467952 TI - Diffusion-weighted imaging in identifying breast cancer pathological response to neoadjuvant chemotherapy: A meta-analysis. AB - Background: Diffusion-weighted imaging (DWI) is increasingly used to identify pathological complete responses (pCRs) to neoadjuvant chemotherapy (NAC) in breast cancer. The aim of the present study was to assess the utility of DWI using a pooled analysis. Materials and Methods: Literature databases were searched prior to July 2017. Fifteen studies with a total of 1181 patients were included. The data were extracted to perform pooled analysis, heterogeneity testing, threshold effect testing, sensitivity analysis, publication bias analysis and subgroup analyses. Result: The methodological quality was moderate. Remarkable heterogeneity was detected, primarily due to a threshold effect. The pooled weighted values were a sensitivity of 0.88 (95% confidence interval (CI): 0.81, 0.92), a specificity of 0.79 (95% CI: 0.70, 0.86), a positive likelihood ratio of 4.1 (95% CI: 2.9, 5.9), a negative likelihood ratio of 0.16 (95% CI: 0.10, 0.24), and a diagnostic odds ratio of 26 (95% CI: 15, 46). The area under the receiver operator characteristic curve was 0.91 (95% CI: 0.88, 0.93). In the subgroup analysis, the pooled specificity of change in the apparent diffusion coefficient (ADC) subgroup was higher than that in the pre-treatment ADC subgroup (0.80 [95% CI: 0.71, 087] vs. 0.63 [95% CI: 0.52, 0.73], P = 0.027). Conclusions: DWI may be an accurate and nonradioactive imaging technique for identifying pCRs to NAC in breast cancer. Nonetheless, there are a variety of issues when assessing DWI techniques for estimating breast cancer responses to NAC, and large scale and well-designed clinical trials are needed to assess the technique's diagnostic value. PMID- 29467953 TI - Meta-analysis of a 10-plex urine-based biomarker assay for the detection of bladder cancer. AB - A 10-plex urine-based bladder cancer (BCa) diagnostic signature has the potential to non-invasively predict the presence of BCa in at-risk patients, as reported in various case-control studies. The present meta-analysis was performed to re evaluate and demonstrate the robustness and consistency of the diagnostic utility of the 10-plex urine-based diagnostic assay. We re-analyzed primary data collected in five previously published case-control studies on the 10-plex diagnostic assay. Studies reported the sensitivity and specificity of ten urinary protein biomarkers for the detection of BCa, including interleukin 8, matrix metalloproteinases 9 and 10, angiogenin, apolipoprotein E, syndecan 1, alpha-1 antitrypsin, plasminogen activator inhibitor-1, carbonic anhydrase 9, and vascular endothelial growth factor A. Data were extracted and reviewed independently by two investigators. Log odds ratios (ORs) were calculated to determine how strongly the 10-plex biomarker panel and individual biomarkers are associated with the presence of BCa. Data pooled from 1,173 patients were analyzed. The log OR for each biomarker was improved by 1.5 or greater with smaller 95% CI in our meta-analysis of the overall cohort compared with each analysis of an individual cohort. The combination of the ten biomarkers showed a higher log OR (log OR: 3.46, 95% CI: 2.60-4.31) than did any single biomarker irrespective of histological grade or disease stage of tumors. We concluded that the 10-plex BCa-associated diagnostic signature demonstrated a higher potential to identify BCa when compared to any single biomarker. Our results justify further advancement of the 10-plex protein-based diagnostic signature toward clinical application. PMID- 29467954 TI - Efficacy and safety of thrombopoietin receptor agonists in children with chronic immune thrombocytopenia: a meta-analysis. AB - Background and Aim: Thrombopoietin receptor agonists (TPO-RAs) have been shown to be safe and effective for adults with chronic immune thrombocytopenia (ITP). The aim of this meta-analysis is to assess the efficacy and safety of thrombopoietin receptor agonists for children with chronic ITP. Materials and Methods: Clinical randomized controlled trials (RCTs) evaluating the efficacy and safety of TPO-RAs in pediatric ITP patients published up to June 2017 were retrieved from PubMed, Cochrane Library, and Embase databases. Relevant data were extracted, and the Physiotherapy Evidence Database scale was used to assess the methodological quality. Stata/SE 12.0 was used to perform a meta-analysis. Results: Seven RCTs were included, with 238 patients and 107 patients in the TPO-RA group and the control group, respectively. Assessing efficacy, better results were found in the TPO-RA group for the rate of overall platelet response, durable response, and rescue medication needed. Furthermore, the TPO-RA group yielded superior results in the incidence of clinically significant bleeding events but had a comparable result in the incidence of any bleeding events and severe bleeding events. No significant difference was found between the two groups in health-related quality of life and parental burden. Assessing safety, no significant difference was found between the two groups in the incidence of any adverse events and severe adverse events. Conclusions: TPO-RAs are effective and safe agents for the treatment of chronic ITP in pediatric patients. Eltrombopag appears to be better than romiplostim in terms of the rate of rescue medication needed and clinically significant bleeding events. PMID- 29467955 TI - Milk/dairy products consumption and gastric cancer: an update meta-analysis of epidemiological studies. AB - The relationship between dairy consumption and gastric cancer risk has not been well studied. We therefore performed a update meta-analysis to evaluate the relationship. Published cohort and case-control studies were identified via computer searches and reviewing the reference lists of the key articles. Random effects meta-analysis was used to pool effects from 5 cohort and 29 case-control studies. The odds ratio for the overall association between dairy consumption and gastric cancer was 1.20 (95%confidence interval: 1.04-1.39). The combined risk estimate was similar for population-based case-control studies (odds ratio = 1.27, 95%confidence interval: 1.00-1.61), but was reduced for hospital-based studies (odds ratio = 1.22; 95%confidence interval: 0.95-1.57) and cohort studies (odds ratio = 0.99; 95%confidence interval: 0.77-1.28). There was high heterogeneity in overall analyses. In the population-based subgroup analyses, the odds ratio was 0.96 (95%confidence interval: 0.69-1.34) when considering five studies assessing exposure two or more years before interview, and the association strengthened (odds ratio = 1.91, 95%confidence interval: 1.60-2.28) when dairy consumption was evaluated one year or less prior to interview. In conclusion, we found adverse effect of dairy consumption associated with gastric cancer. PMID- 29467956 TI - Vitamin D receptor Taq I polymorphism and the risk of prostate cancer: a meta analysis. AB - Numerous previous studies reported the association of Vitamin D receptor gene Taq Ipolymorphism with prostate cancer risk, however these results were controversial. In order to provide a relatively comprehensive description of this relationship, we conducted this meta-analysis by searching PubMed, Embase, and China National Knowledge Infrastructure. Finally, 36 studies with 8,423 cases and 8,887 controls were included. Taq I polymorphism was found to marginally increase the prostate cancer risk in recessive genetic model (tt/Tt vs. TT: Odds Ratio (OR) = 0.89, 95% Confidence Interval (CI) = 0.80-1.00, p = 0.05) and allele genetic model (t vs. T allele: OR = 0.91, 95% CI = 0.84-0.99, p = 0.003) in the overall analysis. Subgroup analyses showed that significant increased risk was found in Asians in homozygote model (tt vs. TT: OR = 0.63, 95% CI = 0.41-0.95, p = 0.029) and allele genetic model (t vs. T: OR = 0.78, 95% CI = 0.67-0.90, p = 0.002), and in the subgroup of population-based controls in all the genetic models. These results suggest that Taq Ipolymorphism might be a risk factor of prostate cancer risk, especially in Asians. It could be considered as a promising target to predict the prostate cancer risk for clinical practice. PMID- 29467957 TI - Gemcitabine-based chemotherapy as a viable option for treatment of advanced breast cancer patients: a meta-analysis and literature review. AB - This meta-analysis was designed to compare the efficacy and safety of gemcitabine based regimens for the treatment advanced breast cancer (ABC). Altogether 15 studies involving 8195 ABC patients were retrieved for analysis. Compared with non-gemcitabine-based chemotherapies, patients receiving gemcitabine-based therapy exhibited better overall survival (OS), progression free survival (PFS), and objective response rate (ORR) (HR = 1.12, 95% CI 1.05 to 1.19; HR = 1.16, 95% CI 1.03 to 1.30; HR = 1.14, 95% CI 1.04 to 1.24). Grade 3/4 hematologic toxicity was significantly high but manageable in gemcitabine-based groups. Subgroup analysis revealed that patients with first-line gemcitabine-based chemotherapy had better OS (HR = 1.19, 95% CI 1.07 to 1.32), PFS (HR = 1.17, 95% CI 1.08 to 1.27), and ORR (RR = 1.16, 95% CI 1.02 to 1.32). In addition, additional gemcitabine chemotherapy also showed better OS (HR = 1.17, 95% CI 1.06 to 1.30), PFS (HR = 1.20, 95% CI 1.11 to 1.30) and ORR (RR = 1.23, 95% CI 1.06 to 1.42) than gemcitabine replacement therapy. Furthermore, patients receiving gemcitabine taxanes-based regimens had better OS (HR = 1.17, 95% CI 1.06 to 1.28), PFS (HR = 1.12, 95% CI 1.04 to 1.20) and ORR (RR = 1.17, 95% CI 1.01 to 1.35) than patients with non-gemcitabine-taxanes-based chemotherapy. These findings indicate that gemcitabine combination regimens could serve as a promising regimen for ABC patients, though increased hematologic toxicity should be considered with caution. PMID- 29467958 TI - Pharmacokinetic properties of radiolabeled mutant Interleukin-2v: a PET imaging study. AB - Interleukin-2 (IL2) is a cytokine that can stimulate cytotoxic immune cells to attack infected and malignant cells. Unfortunately, IL2 can also cause serious immune-related toxicity. Recently, a mutant of IL2 (IL2v) with abolished CD25 binding, increased plasma half-life and less toxicity was engineered. Unlike wild type IL2 (wt-IL2), mutant IL2v does not bind to the alpha-subunit (CD25) of the high affinity IL2alphabetagamma receptor, but only to its beta and gamma subunit. Here, we investigated the biological properties of IL2v and compared with the wt IL2 using fluorine-18 and PET. [18F]FB-IL2v binds specifically to IL2 receptors (IL2R) on activated human peripheral blood monocytes (hPBMCs) and is cleared mainly by the kidneys (Balb/c mice). [18F]FB-IL2v PET studies in SCID mice injected with hPBMCs revealed high uptake in the implant (0.85 +/- 0.15 SUV), which was significantly reduced after pretreatment with wt-IL2 or mutant IL2v (SUV 0.26 +/- 0.1 and 0.46 +/- 0.1, p < 0.01). Compartment modeling and Logan graphical analysis in wistar rats inoculated with hPBMCs indicated that the binding of [18F]FB-IL2v to IL2R was reversible. The volume of distribution (VT) and the non-displaceable binding potential (BPnd) of mutant [18F]FB-IL2v in the implant were approximately 3 times lower than those of wild-type [18F]FB-IL2 (p < 0.01). Pretreatment with wt-IL2 significantly reduced the VT and BPnd of mutant [18F]FB-IL2v in the implant (p < 0.001). This demonstrates that wild-type [18F]FB IL2 binds stronger to IL2R and has faster kinetics than [18F]FB-IL2v, which makes it less suitable as a therapeutic drug. [18F]FB-IL2v, on the other hand, seems to have better properties for use as a therapeutic drug. PMID- 29467959 TI - Apatinib as a third- or further- line treatment in patients with advanced NSCLC harboring wild-type EGFR. AB - Objectives: This study was conducted to evaluate the efficacy and safety of apatinib in advanced NSCLC patients with EGFR wild-type who have failed more than second-line chemotherapy. Materials and Methods: We retrospectively analyzed patients with EGFR wild-type advanced NSCLC who were treated with apatinib from January 2014 to August 2016. Objective response rate (ORR), disease control rate (DCR), progression free survival (PFS), overall survival (OS), and adverse events (AEs) were reveiwed and evaluated. Univariate and multivariate analyses were performed to determine the prognostic factors. Results: 36 patients were evaluable for safety and efficacy. 6 patients obtained partial response, and 21 showed stable disease. The ORR and DCR were 16.7% and 75%, respectively. The median PFS and OS were 4.5 months and 8.2 months, respectively. Prognostic variable for a longer OS was good performance status (p = 0.015). Most adverse reactions were mild or moderate. Conclusions: Apatinib should be recommended as a third- or further- line therapy in advanced NSCLC patients with EGFR wild-type due to its better efficacy and tolerable toxicity. PMID- 29467960 TI - A liquid biopsy for bronchopulmonary/lung carcinoid diagnosis. AB - No effective blood biomarker exists to detect and clinically manage bronchopulmonary (BP) neuroendocrine tumors (NET). We developed a blood-based 51 NET-specific transcript set for diagnosis and monitoring and evaluated clinical performance metrics. It accurately diagnosed the tumor and differentiated stable from progressive disease as determined by RECIST criteria. Gene expression was evaluated in: a) publicly available BPNET transcriptomes (GSE35679); b) two BPNET cell-lines; and c) BPNET tissue with paired blood (n = 7). Blood gene expression was assessed in 194 samples including controls, benign lung diseases, malignant lung diseases and small bowel NETs. A separate validation study in 25 age- and gender-matched BPNETs/controls was performed. Gene expression measured by real time PCR was scored (0-100%; normal: < 14%). Regression analyses, Principal Component Analysis (PCA), hierarchical clustering, Fisher's and non-parametric evaluations were undertaken. All 51 genes were identified in BPNET transcriptomes, tumor samples and cell-lines. Significant correlations were evident between paired tumor and blood (R2:0.63-0.91, p < 0.001). PCA and hierarchical clustering identified blood gene expression was significantly different between lung cancers and benign diseases, including BPNETs. Gene expression was highly correlated (R2: 0.91, p = 1.7 * 10-15) between small bowel and BPNET. For validation, all 25 BPNETs were positive compared to 20% controls (p < 0.0001). Scores were significantly elevated (p < 0.0001) in BPNETs (57 +/- 28%) compared to controls (4 +/- 5%). BPNETs with progressive disease (85 +/- 11%) exhibited higher scores than stable disease (32 +/- 7%, p < 0.0001). Blood measurements accurately diagnosed bronchopulmonary carcinoids, distinguishing stable from progressive disease. This marker panel will have clinical utility as a diagnostic liquid biopsy able to define disease activity and progression in real-time. PMID- 29467961 TI - The outcomes and prognostic factors of acute respiratory failure in the patients 90 years old and over. AB - This retrospective cohort study investigated the outcomes and prognostic factors in nonagenarians (patients 90 years old or older) with acute respiratory failure. Between 2006 and 2016, all nonagenarians with acute respiratory failure requiring invasive mechanical ventilation (MV) were enrolled. Outcomes including in hospital mortality and ventilator dependency were measured. A total of 173 nonagenarians with acute respiratory failure were admitted to the intensive care unit (ICU). A total of 56 patients died during the hospital stay and the rate of in-hospital mortality was 32.4%. Patients with higher APACHE (Acute Physiology and Chronic Health Evaluation) II scores (adjusted odds ratio [OR], 5.91; 95 % CI, 1.55-22.45; p = 0.009, APACHE II scores >= 25 vs APACHE II scores < 15), use of vasoactive agent (adjust OR, 2.67; 95% CI, 1.12-6.37; p = 0.03) and more organ dysfunction (adjusted OR, 11.13; 95% CI, 3.38-36.36, p < 0.001; >= 3 organ dysfunction vs <= 1 organ dysfunction) were more likely to die. Among the 117 survivors, 25 (21.4%) patients became dependent on MV. Female gender (adjusted OR, 3.53; 95% CI, 1.16-10.76, p = 0.027) and poor consciousness level (adjusted OR, 4.98; 95% CI, 1.41-17.58, p = 0.013) were associated with MV dependency. In conclusion, the mortality rate of nonagenarians with acute respiratory failure was high, especially for those with higher APACHE II scores or more organ dysfunction. PMID- 29467962 TI - Inflammatory responses and inflammation-associated diseases in organs. AB - Inflammation is a biological response of the immune system that can be triggered by a variety of factors, including pathogens, damaged cells and toxic compounds. These factors may induce acute and/or chronic inflammatory responses in the heart, pancreas, liver, kidney, lung, brain, intestinal tract and reproductive system, potentially leading to tissue damage or disease. Both infectious and non infectious agents and cell damage activate inflammatory cells and trigger inflammatory signaling pathways, most commonly the NF-kappaB, MAPK, and JAK-STAT pathways. Here, we review inflammatory responses within organs, focusing on the etiology of inflammation, inflammatory response mechanisms, resolution of inflammation, and organ-specific inflammatory responses.

PMID- 29467968 TI - Continuity of Care in Resident Outpatient Clinics: A Scoping Review of the Literature. AB - Background : Continuity between patients and physicians is a core principle of primary care and an accreditation requirement. Resident continuity clinics face challenges in nurturing continuity for their patients and trainees. Objective : We undertook a scoping review of the literature to better understand published benchmarks for resident continuity; the effectiveness of interventions to improve continuity; and the impact of continuity on resident and patient satisfaction, patient outcomes, and resident career choice. Methods : We developed a MEDLINE search strategy to identify articles that defined continuity in residency programs in internal medicine, family medicine, and pediatrics published prior to December 31, 2015, and used a quality evaluation tool to assess included studies. Results : The review includes 34 articles describing 12 different measures of continuity. The usual provider of care and continuity for physician formulas were most commonly utilized, and mean baseline continuity was 56 and 55, respectively (out of a total possible score of 100). Clinic and residency program redesign innovations (eg, advanced access scheduling, team-based care, and block scheduling) were studied and had mixed impact on continuity. Continuity in resident clinics is lower than published continuity rates for independently practicing physicians. Conclusions : Interventions to enhance continuity in resident clinics have mixed effects. More research is needed to understand how changes in continuity affect resident and patient satisfaction, patient outcomes, and resident career choice. A major challenge to research in this area is the lack of empanelment of residents' patients, creating difficulties in scheduling and measuring continuity visits.

PMID- 29467969 TI - "It's Not Just Time Off": A Framework for Understanding Factors Promoting Recovery From Burnout Among Internal Medicine Residents. AB - Background : Burnout rates for internal medicine residents are among the highest of all specialties, yet little is known about how residents recover from burnout. Objective : We identified factors promoting recovery from burnout and factors that assist with the subsequent avoidance of burnout among internal medicine residents. Methods : A purposive sample of postgraduate year 2 (PGY-2), PGY-3, and recent graduates who experienced and recovered from burnout during residency participated in semistructured, 60-minute interviews from June to August 2016. Using qualitative methods derived from grounded theory, saturation of themes occurred after 25 interviews. Coding was performed in an iterative fashion and consensus was reached on major themes. Results : Coding revealed 2 different categories of resident burnout-circumstantial and existential-with differing recovery and avoidance methods. Circumstantial burnout stemmed from self-limited circumstances and environmental triggers. Recovery from, and subsequent avoidance of, circumstantial burnout arose from (1) resolving workplace challenges; (2) nurturing personal lives; and (3) taking time off. In contrast, existential burnout stemmed from a loss of meaning in medicine and an uncertain professional role. These themes were identified around recovery: (1) recognizing burnout and feeling validated; (2) connecting with patients and colleagues; (3) finding meaning in medicine; and (4) redefining a professional identity and role. Conclusions : Our study suggests that residents experience different types of burnout and have variable methods by which they recover from and avoid further burnout. Categorizing residents' burnout into circumstantial versus existential experiences may serve as a helpful framework for formulating interventions. PMID- 29467971 TI - JGME-ALiEM Hot Topics in Medical Education: An Analysis of a Virtual Discussion on Resident Well-Being. AB - Background : Physician well-being is garnering increasing attention. In 2016, the Journal of Graduate Medical Education (JGME) published a review by Kristin Raj, MD, entitled "Well-Being in Residency: A Systematic Review." There is benefit in contextualizing the literature on resident well-being through an academic journal club. Objective : We summarized an asynchronous, online journal club discussion about this systematic review and highlighted themes that were identified in the review. Methods : In January 2017, JGME and the Academic Life in Emergency Medicine (ALiEM) blog facilitated an open-access, online, weeklong journal club on the featured JGME article. Online discussions and interactions were facilitated via blog posts and comments, a video discussion on Google Hangouts on Air, and Twitter. We performed a thematic analysis of the discussion and captured web analytics. Results : Over the first 14 days, the blog post was viewed 1070 unique times across 52 different countries. A total of 130 unique participants on Twitter posted 480 tweets using the hashtag #JGMEscholar. Thematic analysis revealed 5 major domains: the multidimensional nature of well-being, measurement of well-being, description of wellness programs and interventions, creation of a culture of wellness, and critique of the methodology of the review. Conclusions : Our online journal club highlighted several gaps in the current understanding of resident well-being, including the need for consensus on the operational definition, the need for effective instruments to evaluate wellness programs and identify residents in distress, and a national research collaboration to assess wellness programs and their impact on resident well-being. PMID- 29467972 TI - A Qualitative Analysis of Attending Physicians' Use of Shared Decision-Making: Implications for Resident Education. AB - Background : Physicians need to rapidly and effectively facilitate patient centered, shared decision-making (SDM) conversations, but little is known about how residents or attending physicians acquire this skill. Objective : We explored emergency medicine (EM) attending physicians' use of SDM in the context of their experience as former residents and current educators and assessed the implications of these findings on learning opportunities for residents. Methods : We used semistructured interviews with a purposeful sample of EM physicians. Interviews were transcribed verbatim, and 3 research team members performed iterative, open coding of transcripts, building a provisional codebook as work progressed. We analyzed the data with a focus on participants' acquisition and use of skills required for SDM and their use of SDM in the context of resident education. Results : Fifteen EM physicians from academic and community practices were interviewed. All reported using SDM techniques to some degree. Multiple themes noted had negative implications for resident acquisition of this skill: (1) the complex relationships among patients, residents, and attending physicians; (2) residents' skill levels; (3) the setting of busy emergency departments; and (4) individual attending factors. One theme was noted to facilitate resident education: the changing culture-with a cultural shift toward patient-centered care. Conclusions : A constellation of factors may diminish opportunities for residents to acquire and practice SDM skills. Further research should explore residents' perspectives, address the modifiable obstacles identified, and examine whether these issues generalize to other specialties. PMID- 29467973 TI - A Descriptive Analysis of the Use of Twitter by Emergency Medicine Residency Programs. AB - Background : Twitter is increasingly recognized as an instructional tool by the emergency medicine (EM) community. In 2012, the Council of Residency Directors in Emergency Medicine (CORD) recommended that EM residency programs' Twitter accounts be managed solely by faculty. To date, little has been published regarding the patterns of Twitter use by EM residency programs. Objective : We analyzed current patterns in Twitter use among EM residency programs with accounts and assessed conformance with CORD recommendations. Methods : In this mixed methods study, a 6-question, anonymous survey was distributed via e-mail using SurveyMonkey. In addition, a Twitter-based search was conducted, and the public profiles of EM residency programs' Twitter accounts were analyzed. We calculated descriptive statistics and performed a qualitative analysis on the data. Results : Of 168 Accreditation Council for Graduate Medical Education accredited EM programs, 88 programs (52%) responded. Of those programs, 58% (51 of 88) reported having a program-level Twitter account. Residents served as content managers for those accounts in the majority of survey respondents (61%, 28 of 46). Most programs did not publicly disclose the identity or position of their Twitter content manager. We found a wide variety of applications for Twitter, with EM programs most frequently using Twitter for educational and promotional purposes. There is significant variability in the numbers of followers for EM programs' Twitter accounts. Conclusions : Applications and usage among EM residency programs are varied, and are frequently not consistent with current CORD recommendations. PMID- 29467963 TI - New extracellular factors in glioblastoma multiforme development: neurotensin, growth differentiation factor-15, sphingosine-1-phosphate and cytomegalovirus infection. AB - Recent years have seen considerable progress in understanding the biochemistry of cancer. For example, more significance is now assigned to the tumor microenvironment, especially with regard to intercellular signaling in the tumor niche which depends on many factors secreted by tumor cells. In addition, great progress has been made in understanding the influence of factors such as neurotensin, growth differentiation factor-15 (GDF-15), sphingosine-1-phosphate (S1P), and infection with cytomegalovirus (CMV) on the 'hallmarks of cancer' in glioblastoma multiforme. Therefore, in the present work we describe the influence of these factors on the proliferation and apoptosis of neoplastic cells, cancer stem cells, angiogenesis, migration and invasion, and cancer immune evasion in a glioblastoma multiforme tumor. In particular, we discuss the effect of neurotensin, GDF-15, S1P (including the drug FTY720), and infection with CMV on tumor-associated macrophages (TAM), microglial cells, neutrophil and regulatory T cells (Treg), on the tumor microenvironment. In order to better understand the role of the aforementioned factors in tumoral processes, we outline the latest models of intratumoral heterogeneity in glioblastoma multiforme. Based on the most recent reports, we discuss the problems of multi-drug therapy in treating glioblastoma multiforme. PMID- 29467974 TI - Stroke Simulation Improves Acute Stroke Management: A Systems-Based Practice Experience. AB - Background : Literature on the effectiveness of simulation-based medical education programs for caring for acute ischemic stroke (AIS) patients is limited. Objective : To improve coordination and door-to-needle (DTN) time for AIS care, we implemented a stroke simulation training program for neurology residents and nursing staff in a comprehensive stroke center. Methods : Acute stroke simulation training was implemented for first-year neurology residents in July 2011. Simulations were standardized using trained live actors, who portrayed stroke vignettes in the presence of a board-certified vascular neurologist. A debriefing of each resident's performance followed the training. The hospital stroke registry was also used for retrospective analysis. The study population was defined as all patients treated with intravenous tissue plasminogen activator for AIS between October 2008 and September 2014. Results : We identified 448 patients meeting inclusion criteria. Simulation training independently predicted reduction in DTN time by 9.64 minutes (95% confidence interval [CI] -15.28 to 4.01, P = .001) after controlling for age, night/day shift, work week versus weekend, and blood pressure at presentation (> 185/110). Systolic blood pressure higher than 185 was associated with a 14.28-minute increase in DTN time (95% CI 3.36-25.19, P = .011). Other covariates were not associated with any significant change in DTN time. Conclusions : Integration of simulation based-medical education for AIS was associated with a 9.64-minute reduction in DTN time. PMID- 29467975 TI - Implementing a Universal Well-Being Assessment to Mitigate Barriers to Resident Utilization of Mental Health Resources. AB - Background : Physician utilization of well-being resources remains low despite efforts to promote use of these resources. Objective : We implemented a well being assessment for internal medicine residents to improve access and use of mental health services. Methods : We scheduled all postgraduate year 1 (PGY-1) and PGY-2 residents at West Virginia University for the assessment at our faculty and staff assistance program (FSAP). While the assessment was intended to be universal (all residents), we allowed residents to "opt out." The assessment visit consisted of an evaluation by a licensed therapist, who assisted residents with a wellness plan. Anonymous surveys were distributed to all residents, and means were compared by Student's t test. Results : Thirty-eight of 41 PGY-1 and PGY-2 residents (93%) attended the scheduled appointments. Forty-two of 58 residents (72%, including PGY-3s) completed the survey. Of 42 respondents, 28 (67%) attended the assessment sessions, and 14 (33%) did not. Residents who attended the sessions gave mean ratings of 7.8 for convenience (1, not convenient, to 9, very convenient), and 7.9 for feeling embarrassed if colleagues knew they attended (1, very embarrassed, to 9, not embarrassed). Residents who attended the assessment sessions reported they were more likely to use FSAP services in the future, compared with those who did not attend (P < .001). Conclusions : Offering residents a well-being assessment may have mitigated barriers to using counseling resources. The majority of residents who participated had a positive view of the program and indicated they would return to FSAP if they felt they needed counseling.

PMID- 29467977 TI - myTIPreport and Training for Independent Practice: A Tool for Real-Time Workplace Feedback for Milestones and Procedural Skills. AB - Background : Few tools currently exist for effective, accessible delivery of real time, workplace feedback in the clinical setting. Objective : We developed and implemented a real-time, web-based tool for performance-based feedback in the clinical environment. Methods : The tool (myTIPreport) was designed for performance-based feedback to learners on the Accreditation Council for Graduate Medical Education (ACGME) Milestones and procedural skills. "TIP" stands for "Training for Independent Practice." We implemented myTIPreport in obstetrics and gynecology (Ob-Gyn) and female pelvic medicine and reconstructive surgery (FPMRS) programs between November 2014 and May 2015. Residents, fellows, teachers, and program directors completed preimplementation and postimplementation surveys on their perceptions of feedback. Results : Preimplementation surveys were completed by 656 participants of a total of 980 learners and teachers in 19 programs (12 Ob Gyn and 7 FPMRS). This represented 72% (273 of 378) of learners and 64% (383 of 602) of teachers. Seventy percent of participants (381 of 546) reported having their own individual processes for real-time feedback; the majority (79%, 340 of 430) described these processes as informal discussions. Over 6 months, one-third of teachers and two-thirds of learners used the myTIPreport tool a total of 4311 times. Milestone feedback was recorded 944 times, and procedural feedback was recorded 3367 times. Feedback addressed all ACGME Milestones and procedures programmed into myTIPreport. Most program directors reported that tool implementation was successful. Conclusions : The majority of learners successfully received workplace feedback using myTIPreport. This web-based tool, incorporating procedures and ACGME Milestones, may be an important transition from other feedback formats. PMID- 29467979 TI - Programmatic Assessment in Emergency Medicine: Implementation of Best Practices. AB - Background : Programmatic assessment is the intentional collection of key data from multiple sources for both assessment of learning and assessment for learning. Objective : We developed a system of programmatic assessment (PA) to identify competency progression (summative) and assessment for learning to assist residents in their formative development. Methods : The programmatic assessment was designed iteratively from 2014 through 2016. All assessments were first categorized by competency domain and source of assessment. The number of assessment modalities for each competency domain was collected. These multisource assessments were then mapped by program leadership to the milestones to develop a master PA blueprint. A resident learning management system provided the platform for aggregating formative and summative data, allowing residents and faculty ongoing access to guide learning and assessment. A key component of programmatic assessment was to support resident integration of assessment information through feedback by faculty after shifts and during monthly formal assessments, semiannual resident reviews, and summative judgments by the Clinical Competency Committee. Results : Through the PA, the 6 competency domains are assessed through multiple modalities: patient care (22 different assessments), professionalism (18), systems-based practice (17), interprofessional and communication skills (16), medical knowledge (11), and practice-based learning and improvement (6). Each assessment provides feedback to the resident in various formats. Our programmatic assessment has been utilized for more than 2 years with iterative improvements. Conclusions : The implementation of programmatic assessment allowed our program to organize diverse, multisourced feedback to drive both formative and summative assessments. PMID- 29467978 TI - Feasibility of a Comprehensive Medical Knowledge Curriculum in Internal Medicine Using Team-Based Learning. AB - Background : Team-based learning (TBL) is an active learning strategy with descriptions of its use in resident education limited to pilot studies. Objective : We developed a comprehensive medical knowledge TBL curriculum for an internal medicine residency, and assessed feasibility. Methods : We developed a 135-topic TBL curriculum to replace a noon conference lecture series, and implemented it over a 3-year period (2013-2016). In this article we describe the planning, curricular design, faculty recruitment and development, and lesson structure. We assessed feasibility in terms of faculty participation, resident preparedness, resident and faculty satisfaction, and costs. Results : Most faculty initially were unfamiliar with TBL. Through faculty resource materials and flexible faculty development, participating faculty increased from 3 to 74. In a 2015 faculty survey (N = 64, 69% response rate), 73% (32 of 44) reported faculty development was adequate, 70% (31 of 44) indicated lesson preparation time reasonable, and 95% (42 of 44) reported preparation materials were helpful. A 2016 resident survey (N = 89, 72% response rate) revealed that most residents completed reading assignments in advance, 78% (50 of 64) found readings manageable, and 77% (49 of 64) felt they learned better from TBL compared to lectures. Costs included compensated time for 1 faculty TBL "champion" and an assistant. Conclusions : Implementing a comprehensive medical knowledge curriculum using TBL in an internal medicine residency was feasible, and resulted in high faculty acceptance and learner satisfaction. Departmental support of a TBL champion, flexible faculty development, and well-designed resource materials were determinants of success. PMID- 29467980 TI - A Prospective Multicenter Evaluation of the Value of the On-Call Orthopedic Resident. AB - Background : Funding for graduate medical education is at risk despite the services provided by residents. Objective : We quantified the potential monetary value of services provided by on-call orthopedic surgery residents. Methods : We conducted a prospective, cross-sectional, multicenter cohort study design. Over a 90-day period in 2014, we collected data on consults by on-call orthopedic surgery residents at 4 tertiary academic medical centers in the United States. All inpatient and emergency department consults evaluated by first-call residents during the study period were eligible for inclusion. Based on their current procedural terminology codes, procedures and evaluations for each consult were assigned a relative value unit and converted into a monetary value to determine the value of services provided by residents. The primary outcome measures were the total dollar value of each consult and the percentage of resident salaries that could be funded by the generated value of the resident consult services. Results : In total, 2644 consults seen by 33 residents from the 4 institutions were included for analysis. These yielded an average value of $81,868 per center for the 90-day study period, that is, $327,471 annually. With a median resident stipend of $53,992, the extrapolated average percentage of resident stipends that could be funded by these consult revenues was 73% of the stipends of the residents who took call or 36% of the stipends of the overall resident cohort. Conclusions : The potential monetary value generated by on-call orthopedic surgery residents is substantial.

AB - Obesity is a highly prevalent non-communicable disease worldwide and is commonly associated with male infertility. Several etiopathological theories have been mentioned in the literature by which obesity affects spermatogenesis, thus affecting the male fertility potential. Mechanisms for explaining the effect of obesity on male infertility include endocrinopathy, increased aromatization activity, associated erectile dysfunction, psychological and thermal effects, obstructive sleep apnea, increased leptin and oxygen free radicals, and associated inflammatory and obstructive elements of epididymitis. Treatment of such a complex problem includes weight reduction (by lifestyle modification and increased physical activity), optimization of altered testosterone-to-estradiol ratio using aromatase inhibitors and/or gonadotropins, treatment of associated comorbidities by phosphodiesterase inhibitors for erectile dysfunction, and insulin-sensitizing agents for the management of diabetes. The aim of this mini review is to highlight the pathological basis of this problem and to focus on obesity as an etiology of male infertility. PMID- 29467993 TI - Pediatric Renal Transplantation in Oman: A Single-center Experience. AB - Objectives: This study sought to report 22 years experience in pediatric kidney transplantation in Oman. Methods: Electronic charts of all Omani children below 13 years of age who received a kidney transplant from January 1994 to December 2015 were reviewed. Data collected included patient demographics, etiology of end stage kidney disease, modality and duration of dialysis, donor type, complication of kidney transplantation (including surgical complications, infections, graft rejection) graft and patient survival, and duration of follow-up. Results: During the study period transplantation from 27 living related donors (LRDs), 42 living unrelated donors (LURDs), also referred to as commercial transplant, and one deceased donor were performed. The median age at transplantation was nine years for both groups. The most common primary diagnosis was congenital anomalies of the kidney and urinary tract in 32.8% of patients followed by familial nephrotic syndrome in 20.0% and polycystic kidney disease in 18.5%. Almost half the patients were on hemodialysis before transplantation, 35.7% were on peritoneal dialysis, and 14.2% received preemptive renal transplantation. Children who received LURD kidneys had high surgical complications (42.8%) compared to the LRDs group (17.8%). Five patients from LURDs group had early graft nephrectomy and four patients developed non-graft function or delayed graft function. In addition, patients in the LURDs group had a higher incidence of hypertension and acute rejection. Graft and patient survival were both better in the LRDs than the LURDs group. Conclusions: Although our pediatric kidney transplant program is a young program it has had successful patient outcomes comparable to international programs. Our study provides evidence that in addition to legal and ethical issues with commercial transplant, it also carries significantly higher morbidity and reduced graft and patient survival. PMID- 29467994 TI - Neonatal and Obstetrical Outcomes of Pregnancies in Systemic Lupus Erythematosus. AB - Objectives: Systemic lupus erythematous (SLE) is a chronic autoimmune disease that affects women primarily of childbearing age. The objective of this study was to determine the neonatal and maternal outcomes of pregnancies in SLE patients compared to pregnancies in healthy controls. Methods: We conducted a retrospective cohort study in a tertiary care hospital in Oman between January 2007 and December 2013. We analyzed 147 pregnancies and compared 56 (38.0%) pregnancies in women with SLE with 91 (61.9%) pregnancies in healthy control women. Disease activity was determined using the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI). Results: The mean age of the cohort was 30.0+/ 5.0 years ranging from 19 to 44 years old. Patients with SLE were treated with hydroxychloroquine (n = 41; 73.2%), prednisolone (n = 38; 67.8%), and azathioprine (n = 17; 30.3%). There was no disease activity in 39.2% (n = 22) of patients while 41.0% (n = 23), 12.5% (n = 7), and 7.1% (n = 4) had mild (SLEDAI 1 5), moderate (SLEDAI 6-10), and severe (SLEDAI 3 11) disease activity, respectively, at onset of pregnancy. Pregnancies in patients with SLE were associated with higher abortions (42.8% vs. 15.3%; p < 0.001), gestational diabetes (28.3% vs. 10.2%; p = 0.004), polyhydramnios (7.1% vs. 0.0%; p = 0.020), previous preterm pregnancies (8.9% vs. 1.0%; p = 0.030), and intrauterine growth retardation (21.4% vs. 0.0%; p < 0.001) when compared to pregnancies in healthy control women. Furthermore, the neonates born to mothers with SLE were more likely to be preterm (28.5% vs. 1.0%; p < 0.001), have a low birth weight (< 2 500 g) (32.1% vs. 1.0%; p < 0.001), and were associated with stillbirth (7.1% vs. 0.0%; p = 0.010) when compared to neonates born to healthy control mothers. Conclusions: Pregnancies in women with SLE were associated with higher neonatal and maternal complications. Therefore, pregnant women with SLE should have their pregnancy accurately planned, monitored, and managed according to a multidisciplinary treatment schedule. PMID- 29467995 TI - Transitional Female Sacrum: Dimensions, Alterations in Dorsal Pelvic Structure, and Potential Obstetric Implications. AB - Objectives: The space available within the female pelvis is determined by the morphology of all bony components constituting the pelvic skeleton. Although several studies have investigated the impact of hip-bone structural variations in on parturition, the potential effects of commonly occurring lumbosacral transitional vertebrae (LSTV) variations have been underreported. This descriptive morphometric study reports dimensions of the female sacrum associated LSTV variations and suggests their probable mechanistic effects on normal labor. Methods: One hundred and twelve female osteological sacral specimens with LSTV were examined for the type of transitional anomaly. Position, height, and surface areas of the auricular surfaces, interauricular distances, sacral heights, S1 body width and upper surface areas, and articulating areas of S1 facets were measured and compared with data from non-transitional samples. Results: Female LSTV predominantly presented as accessory L5-S1 articulations (unilateral and bilateral) and degrees of lumbarization (separation of the first sacral segment). Since some of these alterations were found to be significantly associated with changes in sacral size, these features, in conjunction with cranial shift of the auricular surfaces, may be associated with overall in dorsal pelvic dimensions. Conclusions: Structural alterations identified in female LSTV sacrum may change dorsal pelvic dimensions and thus, the availability of dorsal pelvic space, potentially altering the biomechanics of normal labor. PMID- 29467996 TI - Strategic Approaches Towards Pertussis Control in Oman. AB - Objectives: Pertussis is a highly contagious disease that causes severe and serious symptoms among infants and young children with fatalities observed in early infancy. The disease is milder among adolescents and adults. In this paper, we describe the progress made towards pertussis control in Oman and the challenges ahead to achieve control and maintain it. Methods: Pertussis data were collected between 1981 and 2015 from various sources including Annual Health Reports, annual Ministry of Health progress reports, and Community Health and Diseases Surveillance Newsletter, which provided information for the calculation of different pertussis indicators. Results: Diphtheria-tetanus-whole cell pertussis 3 (DTwP3) vaccination coverage rose from 19% in 1981 to 97% in 1992 and has been at 3 97% until 2015. The overall incidence of pertussis dropped dramatically from an average of 771 cases per 100 000 population from 1981 through 1985, to 21 cases per 100 000 population between 2011 and 2015 (p < 0.001). Since 1987, pertussis cases were cyclical, with peaks every three to five years with three major outbreaks reported in some parts of the country. Between 2011 and 2015, 831 cases were notified of which 785 (94.4%) met the pertussis case definition. Of these 785 cases, 625 (79.7%) were in children aged < 12 months (average rate 185 per 100 000 population), and almost all were hospitalized. Of the 625, 357 (57.1%) were aged < 2 months (average incidence of 600/100 000 population), 129 (20.6%) were 2-3 months old (average incidence of 202/100 000 population), 80 (12.8%) were 4-6 months (average incidence of 119/100 000 population), and 59 (9.4%) were 6-12 months old (average incidence is 22/100 000 population). There were 160/785 (20.3%) cases reported in children 3 12 months old (average rate 4/100 000 population). Downward trend rates were reported in the 5-14 year age group and a very low disease rate was observed in the > 15 years group. Since 2007, no deaths recorded were attributed to pertussis. Conclusions: Oman has a high coverage of DTP3; however, pertussis control remains a challenge among infants < 12 months old. Therefore, tetanus, diphtheria, and acellular pertussis (Tdap) vaccination of pregnant women is likely to be the best strategy for preventing the disease in infants. PMID- 29467997 TI - Investigation of Class I, II, and III Integrons Among Acinetobacter Baumannii Isolates from Hospitalized Patients in Isfahan, Iran. AB - Objectives: This study aimed to determine the prevalence of class I, II, and III integrons among clinical Acinetobacter baumannii isolates collected from hospitalized patients. Methods: This cross-sectional study was conducted at two teaching hospitals in Isfahan, Iran, from October 2015 to October 2016. A total of 147 non-duplicate A. baumannii isolates were collected from clinical specimens and identified as A. baumannii using standard microbiological methods and confirmed by genotyping. Antimicrobial susceptibility was determined using disc diffusion method, and the presence of integron genes was performed using the polymerase chain reaction. Results: Out of 147 confirmed A. baumannii isolates, 97.3% of isolates were extensive drug-resistant (XDR) and 2.7% were multidrug resistant (MDR). Class I and II integrons were detected in 63.9% and 78.2% of the A. baumannii, respectively. Class III integron was not detected in any of the isolates. Conclusion: Our results show a high prevalence of classes I and II integrons which may play a key role in the acquisition of MDR and XDR phenotype among A. baumannii isolates in our region. Therefore, use of appropriate infection control in clinical settings and implementation of treatment strategies is necessary for our hospitals. PMID- 29467998 TI - Immunophenotypic Characteristics of T-Acute Lymphoblastic Leukemia in Omani Patients: A Correlation with Demographic Factors. AB - Objectives: To study and classify the immunophenotypic characteristics of Omani patients diagnosed with T-cell acute lymphoblastic leukemia (T-ALL) and to correlate the results with age and gender as well as biological factors (peripheral and bone marrow blast cells percentage). Methods: Fifty cases from both genders and of all ages who fulfilled the inclusion criteria with a diagnosis of T-ALL were included in the study. Correlation of T-ALL subtypes with age, gender, and initial bone marrow and peripheral blood blast cells percentage was assessed using ANOVA. Results: Among the 50 T-ALL patients analyzed, 44 were male and six were female giving a male-to-female ratio of 7:1 (p = 0.007). The average age of patients was 19.2 years with no significant differences in the three disease subtypes. No significant association was seen between the peripheral or bone marrow blast cell percentage and the differentiation stages of the neoplastic clone of T-ALL. All female patients were found to express an immature T-ALL phenotype. Conclusions: This study reports the subtypes of T-ALL in Oman for the first time. It is hoped that this will lead to a better understanding of the disease outcomes. PMID- 29467999 TI - The Correlation of Cardiac and Hepatic Hemosiderosis as Measured by T2*MRI Technique with Ferritin Levels and Hemochromatosis Gene Mutations in Iranian Patients with Beta Thalassemia Major. AB - Objectives: Organ-specific hemosiderosis and iron overload complications are more serious and more frequent in some patients with beta thalassemia major (BTM) compared with others. We investigated whether coinheritance of HFE H63D or C282Y gene mutations in patients with BTM contributes to the phenotypic variation of iron overload complications and assessed the correlation of cardiac and hepatic hemosiderosis with plasma ferritin levels. Methods: We studied 60 patients with BTM with a mean age of 17.5+/-9.1 years from the Northwest of Iran. HFE gene mutations were analyzed using the polymerase chain reaction-restriction fragment length polymorphism method. Cardiac and hepatic hemosiderosis was assessed using T2*magnetic resonance imaging (MRI). Ferritin levels were measured using the enzyme immunoassay method. Results: Ferritin levels showed a strong inverse correlation with hepatic T2*MRI values (r = -0.631, p = 0.001) but a poor correlation with cardiac T2*MRI values (r = -0.297, p = 0.044). The correlation between cardiac T2*MRI values and hepatic T2*MRI values was poor and insignificant (r = 0.287, p = 0.058). Genotype and allele distribution of HFE H63D and C282Y mutation did not differ significantly between patients with and without hepatic or cardiac hemosiderosis (p > 0.050). However, carriers of HFE 63D allele had significantly higher ferritin levels compared with non-carriers (1 903+/-993 vs. 992+/-683, p < 0.001). Conclusions: Cardiac T2*MRI values showed a poor correlation with hepatic T2*MRI values and ferritin levels. Accurate assessment of cardiac iron overload in patients with BTM can only be done using the T2*MRI technique. Additionally, HFE H63D is a significant determinant factor for elevated ferritin levels in BTM patients. PMID- 29468000 TI - An Accurate Diagnostic Pathway Helps to Correctly Distinguish Between the Possible Causes of Acute Scrotum. AB - Objectives: We sought to identify a simplified approach for the rapid differential diagnosis of patients presenting with acute scrotum. Methods: A total of 440 patients referred to the emergency department of the University Hospital of Bern, Switzerland, with acute scrotum between 2003 and 2013 were retrospectively analyzed. Simple and multiple binary logistic regression analyses were used to evaluate clinical and laboratory parameters that may help to distinguish between genital/paragenital infection and acute testicular torsion. Results: Over half (58.4%; 257/440) of the patients were diagnosed with genital/paragenital infection, 11.8% (52/440) with chronic testicular pain, 9.5% (42/440) with acute testicular torsion, 4.3% (19/440) with a testicular cancer, and 2.5% (11/440) with symptomatic distal ureterolithiasis. In multivariate analysis, a positive Prehn's sign was predictive of testicular torsion, whereas fever, dysuria, high leucocyte counts in blood and/or urine, high blood C reactive protein, and burning pain were predictive of genital/paragenital infection. Color Doppler ultrasound did not help to distinguish between torsion and infection. Conclusions: An accurate diagnostic pathway helps to correctly distinguish between the possible causes of acute scrotum. However, none of the examinations performed could reliably distinguish between acute torsion and other causes of acute scrotum. Therefore, immediate surgical exploration of the testis is mandatory if torsion cannot be ruled out. PMID- 29468001 TI - Cerebral Venous Sinus Thrombosis in a Patient with Meningococcal Meningitis. AB - Meningococcal meningitis has a wide range of neurological complications. However, cerebral venous sinus thrombosis (CVST) following infection with Neisseria meningitidis is uncommon. We report a case of CVST in a 42-year-old male admitted with meningococcal meningitis. The patient was managed with antibiotics. Due to altered coagulation parameters observed in fulminant cases of meningococcemia, deployment of anticoagulation therapy, which would otherwise be the treatment of choice for CVST, is a dilemma. PMID- 29468002 TI - Idiopathic Non-traumatic Facial Nerve Palsy (Bell's Palsy) in Neonates; An Atypical Age and Management Dilemma. AB - Idiopathic (Bell's) palsy is the commonest cause of unilateral facial paralysis in children. Although being idiopathic by definition, possible infectious, inflammatory, and ischemic triggers have been suggested. Bell's palsy is thought to be responsible for up to three-fourths of cases of acute unilateral facial paralysis worldwide. The diagnosis has to be reached after other causes of acute peripheral palsy have been excluded. However, it is rarely described in neonates and young infants. Steroids may have some role in treatment, but antiviral therapies have doubtful evidence of benefit. Prognosis is good, though residual dysfunction is occasionally encountered. We report the case of a two-week-old neonate with no prior illnesses who presented with acute left facial palsy. Clinical findings and normal brain imaging were consistent with the diagnosis of Bell's palsy. The patient had a good response to oral steroids. PMID- 29468003 TI - Obstructed Hemivagina and Ipsilateral Renal Anomaly (OHVIRA) Syndrome. AB - Obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) syndrome is a rare congenital abnormality of the female urogenital tract. We reported OHVIRA syndrome in a 15-year-old girl, who was referred to King Faisal Specialist Hospital and Research Centre, due to hematocolpos and an imperforate hymen. The patient was diagnosed as having an absent right kidney since childhood. She presented with progressive development of lower abdominal discomfort and an abdominopelvic mass. She had no history of urinary complaints. Here, we describe our findings from the abdominal ultrasound and magnetic resonance imaging. PMID- 29468004 TI - Fine-needle Aspiration Cytology of Abdominal Wall Endometriosis: ?A Meaningful Adjunct to Diagnosis. AB - Fine-needle aspiration cytology (FNAC) is a simple, non-invasive diagnostic modality which can be performed with ease on any superficially palpable lesion. Surgical scar endometriosis is a rare entity which presents as an abdominal lump in women of reproductive age. It is often a diagnostic pitfall for clinicians due to its nonspecific symptoms. It displays characteristic morphology, which needs to be identified and recognized by a cytopathologist for accurate diagnosis. FNAC can be used as a key diagnostic tool in cases of abdominal wall mass for appropriate patient management, thereby avoiding unnecessary diagnostic procedures. Here, we report the case of a 35-year-old woman who presented with an abdominal lump where FNAC played a vital role in the patient's management. PMID- 29468005 TI - Assessment of Trained Hand Hygiene Observers Using Parallel Observations. AB - Objectives: To validate hand hygiene (HH) observers following training and determine the concordance between the observers and the Kappa index. Methods: This study was conducted during June 2017. HH observers from 15 hospital units received eight-hours training including a two-hour workshop conducted by the infection control practitioner and hospital epidemiologist. After its completion, parallel observations were conducted by trained nurses from each respective unit for a maximum of 20 minutes per session at any time or day. Results: A total of 789 parallel observations were performed. In observed HH actions, the percentage of agreement between trained and experienced observers was 75.4%, with a Kappa index of agreement of 0.61 (95% confidence interval (CI): 0.57-0.66). For the observed HH moments, the agreement among observers was 83.8% with a Kappa index of 0.71 (95% CI: 0.66-0.75). Conclusions: HH observers were validated after a dedicated training in correspondence with the recommendation to improve HH monitoring. Additional studies should focus on evaluating the sustainability of the agreement, the requirement of retraining, and other alternatives for observers' validation.

PMID- 29468009 TI - Is Red Heavier Than Yellow Even for Blind? AB - Across cultures and languages, people find similarities between the products of different senses in mysterious ways. By studying what is called cross-modal correspondences, cognitive psychologists discovered that lemons are fast rather than slow, boulders are sour, and red is heavier than yellow. Are these cross modal correspondences established via sensory perception or can they be learned merely through language? We contribute to this debate by demonstrating that early blind people who lack the perceptual experience of color also think that red is heavier than yellow but to a lesser extent than sighted do. PMID- 29468011 TI - Ligase IV inhibitor SCR7 enhances gene editing directed by CRISPR-Cas9 and ssODN in human cancer cells. AB - Background: Precise genome editing is essential for both basic and translational research. The recently developed CRISPR/Cas9 system can specifically cleave a designated site of target gene to create a DNA double-strand break, which triggers cellular DNA repair mechanism of either inaccurate non-homologous end joining, or site-specific homologous recombination. Unfortunately, homology directed repair (HDR) is challenging due to its very low efficiency. Herein, we focused on improving the efficiency of HDR using a combination of CRISPR/Cas9, eGFP, DNA ligase IV inhibitor SCR7, and single-stranded oligodeoxynucleotides (ssODN) in human cancer cells. Results: When Cas9, gRNA and eGFP were assembled into a co-expression vector, the disruption rate more than doubled following GFP positive cell sorting in transfected cells compared to those unsorted cells. Using ssODNs as templates, SCR7 treatment increased targeted insertion efficiency threefold in transfected cells compared to those without SCR7 treatment. Moreover, this combinatorial approach greatly improved the efficiency of HDR and targeted gene mutation correction at both the GFP-silent mutation and the beta catenin Ser45 deletion mutation cells. Conclusion: The data of this study suggests that a combination of co-expression vector, ssODN, and ligase IV inhibitor can markedly improve the CRISPR/Cas9-directed gene editing, which should have significant application in targeted gene editing and genetic disease therapy. PMID- 29468012 TI - The use of nutritional guidance within chiropractic patient management: a survey of 333 chiropractors from the ACORN practice-based research network. AB - Background: Food consumption and nutritional status affect an individual's health throughout their life-course and an unhealthy diet is a major risk factor for the current global burden of chronic disease. The promotion of health and good nutrition through healthy eating requires the active involvement of all health professionals including chiropractors. This paper reports findings from the first nationally representative examination of the use of nutritional guidance within chiropractic patient management in Australia. Methods: A sample of 1000 practising chiropractors was randomly selected from the Australian Chiropractic Research Network (ACORN) practice-based research network database for a cross sectional study and 33% participated in the online survey in November 2016. The questionnaire, based on previous designs used in similar surveys and nutrition resources developed by the National Health and Medical Research Council, was pretested prior to the survey. Pearson's Chi square and bivariate logistic regression were undertaken to explore relationships with variables of interest. Results: The demographic details of the respondents are similar to those of the chiropractic workforce registered in Australia. Most chiropractors provided nutritional advice as part of their patient care and around a quarter provided specific dietary advice to their patients, including the use of nutrition supplements. Nutrition-related conditions most commonly encountered by the chiropractors were musculoskeletal, usually inflammatory in origin. Common nutritional assessment methods used included questioning patients to assess their nutritional and health status and physical appearance. Most of the participants provided nutritional resources to their patients in their clinics. However, the Australian Dietary Guidelines and the accompanying Australian Guide to Healthy Eating were not well utilised by the respondents. Australian chiropractors often referred patients with nutrition issues to qualified dietitians and other health professionals when deemed necessary. Conclusions: Australian chiropractors regularly provide nutritional advice and appear to acknowledge the importance of nutrition in their clinical practice especially for patients presenting with chronic disease. If chiropractors are to fulfil their potential in providing such wider public health and preventative health advice to patients, further research examining the utilisation of evidence-based nutrition resources within chiropractic patient management is recommended. PMID- 29468013 TI - Infrared heater system for warming tropical forest understory plants and soils. AB - The response of tropical forests to global warming is one of the largest uncertainties in predicting the future carbon balance of Earth. To determine the likely effects of elevated temperatures on tropical forest understory plants and soils, as well as other ecosystems, an infrared (IR) heater system was developed to provide in situ warming for the Tropical Responses to Altered Climate Experiment (TRACE) in the Luquillo Experimental Forest in Puerto Rico. Three replicate heated 4-m-diameter plots were warmed to maintain a 4 degrees C increase in understory vegetation compared to three unheated control plots, as sensed by IR thermometers. The equipment was larger than any used previously and was subjected to challenges different from those of many temperate ecosystem warming systems, including frequent power surges and outages, high humidity, heavy rains, hurricanes, saturated clayey soils, and steep slopes. The system was able to maintain the target 4.0 degrees C increase in hourly average vegetation temperatures to within +/- 0.1 degrees C. The vegetation was heterogeneous and on a 21 degrees slope, which decreased uniformity of the warming treatment on the plots; yet, the green leaves were fairly uniformly warmed, and there was little difference among 0-10 cm depth soil temperatures at the plot centers, edges, and midway between. Soil temperatures at the 40-50 cm depth increased about 3 degrees C compared to the controls after a month of warming. As expected, the soil in the heated plots dried faster than that of the control plots, but the average soil moisture remained adequate for the plants. The TRACE heating system produced an adequately uniform warming precisely controlled down to at least 50-cm soil depth, thereby creating a treatment that allows for assessing mechanistic responses of tropical plants and soil to warming, with applicability to other ecosystems. No physical obstacles to scaling the approach to taller vegetation (i.e., trees) and larger plots were observed. PMID- 29468014 TI - A comparative analysis of Wolbachia-induced host reproductive phenotypes reveals transition rate heterogeneity. AB - The endosymbiotic bacterium Wolbachia infects a wide range of arthropods and their relatives. It is an intracellular parasite transmitted through the egg from mother to offspring. Wolbachia can spread and persist through various means of host reproductive manipulation. How these different mechanisms of host manipulation evolved in Wolbachia is unclear. Which host reproductive phenotype is most likely to be ancestral and whether evolutionary transitions between some host phenotypes are more common than others remain unanswered questions. Recent studies have revealed multiple cases where the same Wolbachia strain can induce different reproductive phenotypes in different hosts, raising the question to what degree the induced host phenotype should be regarded as a trait of Wolbachia. In this study, we constructed a phylogenetic tree of Wolbachia and analyzed the patterns of host phenotypes along that tree. We were able to detect a phylogenetic signal of host phenotypes on the Wolbachia tree, indicating that the induced host phenotype can be regarded as a Wolbachia trait. However, we found no clear support for the previously stated hypothesis that cytoplasmic incompatibility is ancestral to Wolbachia in arthropods. Our analysis provides evidence for heterogeneous transition rates between host phenotypes. PMID- 29468015 TI - You stay, but I Hop: Host shifting near and far co-dominated the evolution of Enchenopa treehoppers. AB - The importance and prevalence of phylogenetic tracking between hosts and dependent organisms caused by co-evolution and shifting between closely related host species have been debated for decades. Most studies of phylogenetic tracking among phytophagous insects and their host plants have been limited to insects feeding on a narrow range of host species. However, narrow host ranges can confound phylogenetic tracking (phylogenetic tracking hypothesis) with host shifting between hosts of intermediate relationship (intermediate hypothesis). Here, we investigated the evolutionary history of the Enchenopa binotata complex of treehoppers. Each species in this complex has high host fidelity, but the entire complex uses hosts across eight plant orders. The phylogenies of E. binotata were reconstructed to evaluate whether (1) tracking host phylogeny; or (2) shifting between intermediately related host plants better explains the evolutionary history of E. binotata. Our results suggest that E. binotata primarily shifted between both distant and intermediate host plants regardless of host phylogeny and less frequently tracked the phylogeny of their hosts. These findings indicate that phytophagous insects with high host fidelity, such as E. binotata, are capable of adaptation not only to closely related host plants but also to novel hosts, likely with diverse phenology and defense mechanisms. PMID- 29468016 TI - Are Hong Kong and Taiwan stepping-stones for invasive species to the mainland of China? AB - Understanding the origins and introduction pathways of invasive species is a fundamental issue for invasion biology, which is necessary for predicting and preventing future invasion. Once an invasive species is established in a new location, this location could serve as a stepping-stone for further invasions. However, such "stepping-stone" effect has not been widely investigated. Using the published literature and records, we compiled the first found locations of 127 top invasive species in China. Our study showed that the most common landing spots of these invasive species were Hong Kong (22 species) and Taiwan (20 species), which accounted for one-third of the invasive species in China. Our analysis revealed that the invasive species in mainland China were more likely to transport from Hong Kong than Macau, a neighboring region with a similar area and colonial history. Similarly, more invasive species were also first landed on Taiwan than Hainan, a nearby island sharing similar climate conditions. Together, our findings indicate that Hong Kong and Taiwan are the most important stepping stones for invasive species to the mainland of China and suggesting that the increasing trade exchange of China's coastal ports constitutes a potential risk for the spread of more invasive species. We suppose that they would be the future stepping-stones for invasive species to the mainland of China and these coastal ports regions where improved biosecurity is needed now. PMID- 29468017 TI - Useful surrogates of soil texture for plant ecologists from airborne gamma-ray detection. AB - Plant ecologists require spatial information on functional soil properties but are often faced with soil classifications that are not directly interpretable or useful for statistical models. Sand and clay content are important soil properties because they indicate soil water-holding capacity and nutrient content, yet these data are not available for much of the landscape. Remotely sensed soil radiometric data offer promise for developing statistical models of functional soil properties applicable over large areas. Here, we build models linking radiometric data for an area of 40,000 km2 with soil physicochemical data collected over a period of 30 years and demonstrate a strong relationship between gamma radiometric potassium (40K), thorium (232Th), and soil sand and clay content. Our models showed predictive performance of 43% with internal cross validation (to held-out data) and ~30% for external validation to an independent test dataset. This work contributes to broader availability and uptake of remote sensing products for explaining patterns in plant distribution and performance across landscapes. PMID- 29468018 TI - Does governance play a role in the distribution of invasive alien species? AB - Invasive alien species (IAS) constitute a major threat to global biological diversity. In order to control their spread, a detailed understanding of the factors influencing their distribution is essential. Although international trade is regarded as a major force structuring spatial patterns of IAS, the role of other social factors remains unclear. Despite studies highlighting the importance of strong governance in slowing drivers of biodiversity loss such as logging, deforestation, and agricultural intensification, no study has yet analyzed its contribution to the issue of IAS. Using estimates of governance quality and comprehensive spatiotemporal IAS data, we performed multiple linear regressions to investigate the effect of governance quality upon the distribution of species listed under "100 of the worst" IAS in 38 Eurasian countries as defined by DASIE. Our model suggested that for countries with higher GDP, stronger governance was associated with a greater number of the worst IAS; in contrast, for the lowest GDP countries under analysis, stronger governance was associated with fewer of these IAS. We elucidate how the quality of governance within a country has implications for trade, tourism, transport, legislation, and economic development, all of which influence the spread of IAS. While our findings support the common assumption that strengthening governance benefits conservation interventions in countries of smaller economy, we find that this effect is not universal. Stronger governance alone cannot adequately address the problem of IAS, and targeted action is required in relatively high-GDP countries in order to stem the influx of IAS associated with high volumes of trade. PMID- 29468019 TI - Disentangling population strategies of two cladocerans adapted to different ultraviolet regimes. AB - Zooplankton have evolved several mechanisms to deal with environmental threats, such as ultraviolet radiation (UVR), and in order to identify strategies inherent to organisms exposed to different UVR environments, we here examine life-history traits of two lineages of Daphnia pulex. The lineages differed in the UVR dose they had received at their place of origin from extremely high UVR stress at high altitude Bolivian lakes to low UVR stress near the sea level in temperate Sweden. Nine life-history variables of each lineage were analyzed in laboratory experiments in the presence and the absence of sub-lethal doses of UVR (UV-A band), and we identified trade-offs among variables through structural equation modeling (SEM). The UVR treatment was detrimental to almost all life-history variables of both lineages; however, the Daphnia historically exposed to higher doses of UVR (HighUV) showed a higher overall fecundity than those historically exposed to lower doses of UVR (LowUV). The total offspring and ephippia production, as well as the number of clutches and number of offspring at first reproduction, was directly affected by UVR in both lineages. Main differences between lineages involved indirect effects that affected offspring production as the age at first reproduction. We here show that organisms within the same species have developed different strategies as responses to UVR, although no increased physiological tolerance or plasticity was shown by the HighUV lineage. In addition to known tolerance strategies to UVR, including avoidance, prevention, or repairing of damages, we here propose a population strategy that includes early reproduction and high fertility, which we show compensated for the fitness loss imposed by UVR stress. PMID- 29468020 TI - Life-history traits and physiological limits of the alpine fly Drosophila nigrosparsa (Diptera: Drosophilidae): A comparative study. AB - Interspecific variation in life-history traits and physiological limits can be linked to the environmental conditions species experience, including climatic conditions. As alpine environments are particularly vulnerable under climate change, we focus on the montane-alpine fly Drosophila nigrosparsa. Here, we characterized some of its life-history traits and physiological limits and compared these with those of other drosophilids, namely Drosophila hydei, Drosophila melanogaster, and Drosophila obscura. We assayed oviposition rate, longevity, productivity, development time, larval competitiveness, starvation resistance, and heat and cold tolerance. Compared with the other species assayed, D. nigrosparsa is less fecund, relatively long-living, starvation susceptible, cold adapted, and surprisingly well heat adapted. These life-history characteristics provide insights into invertebrate adaptations to alpine conditions which may evolve under ongoing climate change. PMID- 29468021 TI - Aberrant clones: Birth order generates life history diversity in Greater Duckweed, Spirodela polyrhiza. AB - Environmental unpredictability is known to result in the evolution of bet-hedging traits. Variable dormancy enhances survival through harsh conditions, and is widely cited as a diversification bet-hedging trait. The floating aquatic plant, Spirodela polyrhiza (Greater Duckweed), provides an opportunity to study diversification because although partially reliable seasonal cues exist, its growing season is subject to an unpredictable and literally "hard" termination when the surface water freezes, and overwinter survival depends on a switch from production of normal daughter fronds to production of dense, sinking "turions" prior to freeze-over. The problem for S. polyrhiza is that diversified dormancy behavior must be generated among clonally produced, genetically identical offspring. Variation in phenology has been observed in the field, but its sources are unknown. Here, we investigate sources of phenological variation in turion production, and test the hypothesis that diversification in turion phenology is generated within genetic lineages through effects of parental birth order. As expected, phenotypic plasticity to temperature is expressed along a thermal gradient; more interestingly, parental birth order was found to have a significant and strong effect on turion phenology: Turions are produced earlier by late birth-order parents. These results hold regardless of whether turion phenology is measured as first turion birth order, time to first turion, or turion frequency. This study addresses a question of current interest on potential mechanisms generating diversification, and suggests that consistent phenotypic differences across birth orders generate life history variation. PMID- 29468022 TI - How to tackle chemical communication? Relative proportions versus semiquantitative determination of compounds in lizard chemical secretions. AB - Knowledge about chemical communication in some vertebrates is still relatively limited. Squamates are a glaring example of this, even when recent evidences indicate that scents are involved in social and sexual interactions. In lizards, where our understanding of chemical communication has considerably progressed in the last few years, many questions about chemical interactions remain unanswered. A potential reason for this is the inherent complexity and technical limitations that some methodologies embody when analyzing the compounds used to convey information. We provide here a straightforward procedure to analyze lizard chemical secretions based on gas chromatography coupled to mass spectrometry that uses an internal standard for the semiquantification of compounds. We compare the results of this method with those obtained by the traditional procedure of calculating relative proportions of compounds. For such purpose, we designed two experiments to investigate if these procedures allowed revealing changes in chemical secretions 1) when lizards received previously a vitamin dietary supplementation or 2) when the chemical secretions were exposed to high temperatures. Our results show that the procedure based on relative proportions is useful to describe the overall chemical profile, or changes in it, at population or species levels. On the other hand, the use of the procedure based on semiquantitative determination can be applied when the target of study is the variation in one or more particular compounds of the sample, as it has proved more accurate detecting quantitative variations in the secretions. This method would reveal new aspects produced by, for example, the effects of different physiological and climatic factors that the traditional method does not show. PMID- 29468023 TI - Community-level plant-soil feedbacks explain landscape distribution of native and non-native plants. AB - Plant-soil feedbacks (PSFs) have gained attention for their potential role in explaining plant growth and invasion. While promising, most PSF research has measured plant monoculture growth on different soils in short-term, greenhouse experiments. Here, five soil types were conditioned by growing one native species, three non-native species, or a mixed plant community in different plots in a common-garden experiment. After 4 years, plants were removed and one native and one non-native plant community were planted into replicate plots of each soil type. After three additional years, the percentage cover of each of the three target species in each community was measured. These data were used to parameterize a plant community growth model. Model predictions were compared to native and non-native abundance on the landscape. Native community cover was lowest on soil conditioned by the dominant non-native, Centaurea diffusa, and non native community cover was lowest on soil cultivated by the dominant native, Pseudoroegneria spicata. Consistent with plant growth on the landscape, the plant growth model predicted that the positive PSFs observed in the common-garden experiment would result in two distinct communities on the landscape: a native plant community on native soils and a non-native plant community on non-native soils. In contrast, when PSF effects were removed, the model predicted that non native plants would dominate all soils, which was not consistent with plant growth on the landscape. Results provide an example where PSF effects were large enough to change the rank-order abundance of native and non-native plant communities and to explain plant distributions on the landscape. The positive PSFs that contributed to this effect reflected the ability of the two dominant plant species to suppress each other's growth. Results suggest that plant dominance, at least in this system, reflects the ability of a species to suppress the growth of dominant competitors through soil-mediated effects.

AB - Senescence is a highly variable process that comprises both age-dependent and state-dependent components and can be greatly affected by environmental conditions. However, few studies have quantified the magnitude of age-dependent and state-dependent senescence in key life-history traits across individuals inhabiting different spatially structured and seasonal environments. We used longitudinal data from wild female yellow-bellied marmots (Marmota flaviventer), living in two adjacent environments that differ in elevation and associated phenology, to quantify how age and individual state, measured as "time to death," affect body mass senescence in different environments. Further, we quantified how patterns of senescence differed between two biologically distinct seasons, spring, and late summer. Body mass senescence had an age-dependent component, expressed as a decrease in mass in old age. Overall, estimated age-dependent senescence was greater in females living in the more favorable lower elevation environment, than in the harsher higher elevation environment, and greater in late summer than in spring. Body mass senescence also had a state-dependent component, captured by effects of time to death, but only in the more favorable lower elevation environment. In spring, body mass gradually decreased from 2 years before death, whereas in late summer, state-dependent effects were expressed as a terminal decrease in body mass in the last year of life. Contrary to expectations, we found that senescence was more likely to be observed under more favorable environmental conditions, rather than under harsher conditions. By further demonstrating that senescence patterns differ among seasons, our results imply that within-year temporal environmental variation must be considered alongside spatial environmental variation in order to characterize and understand the pattern and magnitude of senescence in wild populations. PMID- 29468025 TI - Range contraction and increasing isolation of a polar bear subpopulation in an era of sea-ice loss. AB - Climate change is expected to result in range shifts and habitat fragmentation for many species. In the Arctic, loss of sea ice will reduce barriers to dispersal or eliminate movement corridors, resulting in increased connectivity or geographic isolation with sweeping implications for conservation. We used satellite telemetry, data from individually marked animals (research and harvest), and microsatellite genetic data to examine changes in geographic range, emigration, and interpopulation connectivity of the Baffin Bay (BB) polar bear (Ursus maritimus) subpopulation over a 25-year period of sea-ice loss. Satellite telemetry collected from n = 43 (1991-1995) and 38 (2009-2015) adult females revealed a significant contraction in subpopulation range size (95% bivariate normal kernel range) in most months and seasons, with the most marked reduction being a 70% decline in summer from 716,000 km2 (SE 58,000) to 211,000 km2 (SE 23,000) (p < .001). Between the 1990s and 2000s, there was a significant shift northward during the on-ice seasons (2.6 degrees shift in winter median latitude, 1.1 degrees shift in spring median latitude) and a significant range contraction in the ice-free summers. Bears in the 2000s were less likely to leave BB, with significant reductions in the numbers of bears moving into Davis Strait (DS) in winter and Lancaster Sound (LS) in summer. Harvest recoveries suggested both short and long-term fidelity to BB remained high over both periods (83-99% of marked bears remained in BB). Genetic analyses using eight polymorphic microsatellites confirmed a previously documented differentiation between BB, DS, and LS; yet weakly differentiated BB from Kane Basin (KB) for the first time. Our results provide the first multiple lines of evidence for an increasingly geographically and functionally isolated subpopulation of polar bears in the context of long-term sea-ice loss. This may be indicative of future patterns for other polar bear subpopulations under climate change. PMID- 29468026 TI - The effect of isolation, fragmentation, and population bottlenecks on song structure of a Hawaiian honeycreeper. AB - Little is known about how important social behaviors such as song vary within and among populations for any of the endemic Hawaiian honeycreepers. Habitat loss and non-native diseases (e.g., avian malaria) have resulted in isolation and fragmentation of Hawaiian honeycreepers within primarily high elevation forests. In this study, we examined how isolation of Hawai'i 'amakihi (Chlorodrepanis virens) populations within a fragmented landscape influences acoustic variability in song. In the last decade, small, isolated populations of disease tolerant 'amakihi have been found within low elevation forests, allowing us to record 'amakihi songs across a large elevational gradient (10-1800 m) that parallels disease susceptibility on Hawai'i island. To understand underlying differences among populations, we examined the role of geographic distance, elevation, and habitat structure on acoustic characteristics of 'amakihi songs. We found that the acoustic characteristics of 'amakihi songs and song-type repertoires varied most strongly across an elevational gradient. Differences in 'amakihi song types were primarily driven by less complex songs (e.g., fewer frequency changes, shorter songs) of individuals recorded at low elevation sites compared to mid and high elevation populations. The reduced complexity of 'amakihi songs at low elevation sites is most likely shaped by the effects of habitat fragmentation and a disease-driven population bottleneck associated with avian malaria, and maintained through isolation, localized song learning and sharing, and cultural drift. These results highlight how a non-native disease through its influence on population demographics may have also indirectly played a role in shaping the acoustic characteristics of a species. PMID- 29468027 TI - Age-dependent, negative heterozygosity-fitness correlations and local effects in an endangered Caribbean reptile, Iguana delicatissima. AB - Inbreeding depression can have alarming impacts on threatened species with small population sizes. Assessing inbreeding has therefore become an important focus of conservation research. In this study, heterozygosity-fitness correlations (HFCs) were measured by genotyping 7 loci in 83 adult and 184 hatchling Lesser Antillean Iguanas, Iguana delicatissima, at a communal nesting site in Dominica to assess the role of inbreeding depression on hatchling fitness and recruitment to the adult population in this endangered species. We found insignificant correlations between multilocus heterozygosity and multiple fitness proxies in hatchlings and adults. Further, multilocus heterozygosity did not differ significantly between hatchlings and adults, which suggests that the survivorship of homozygous hatchlings does not differ markedly from that of their heterozygous counterparts. However, genotypes at two individual loci were correlated with hatching date, a finding consistent with the linkage between specific marker loci and segregating deleterious recessive alleles. These results provide only modest evidence that inbreeding depression influences the population dynamics of I. delicatissima on Dominica. PMID- 29468028 TI - Paleoecological evidence for decadal increase in phytoplankton biomass off northwestern Australia in response to climate change. AB - Ocean warming can modify the phytoplankton biomass on decadal scales. Significant increases in sea surface temperature (SST) and rainfall in the northwest of Australia over recent decades are attributed to climate change. Here, we used four biomarker proxies (TEX86 index, long-chain n-alkanes, brassicasterol, and dinosterol) to reconstruct approximately 60-year variations of SST, terrestrial input, and diatom and dinoflagellate biomass in the coastal waters of the remote Kimberley region. The results showed that the most significant increases in SST and terrestrial input occurred since 1997, accompanied by an abrupt increase in diatom and dinoflagellate biomasses. Compared with the results before 1997, the average TEX86H temperature during 1997-2011 increased approximately 1 degrees C, rainfall increased 248.2 mm, brassicasterol and dinosterol contents increased 8.5 and 1.7 times. Principal component analysis indicated that the warming SST played a more important role in the phytoplankton increase than increased rainfall and river discharge. PMID- 29468029 TI - Patterns of activity and body temperature of Aldabra giant tortoises in relation to environmental temperature. AB - We studied the temperature relations of wild and zoo Aldabra giant tortoises (Aldabrachelys gigantea) focusing on (1) the relationship between environmental temperature and tortoise activity patterns (n = 8 wild individuals) and (2) on tortoise body temperature fluctuations, including how their core and external body temperatures vary in relation to different environmental temperature ranges (seasons; n = 4 wild and n = 5 zoo individuals). In addition, we surveyed the literature to review the effect of body mass on core body temperature range in relation to environmental temperature in the Testudinidae. Diurnal activity of tortoises was bimodally distributed and influenced by environmental temperature and season. The mean air temperature at which activity is maximized was 27.9 degrees C, with a range of 25.8-31.7 degrees C. Furthermore, air temperature explained changes in the core body temperature better than did mass, and only during the coldest trial, did tortoises with higher mass show more stable temperatures. Our results, together with the overall Testudinidae overview, suggest that, once variation in environmental temperature has been taken into account, there is little effect of mass on the temperature stability of tortoises. Moreover, the presence of thermal inertia in an individual tortoise depends on the environmental temperatures, and we found no evidence for inertial homeothermy. Finally, patterns of core and external body temperatures in comparison with environmental temperatures suggest that Aldabra giant tortoises act as mixed conformer-regulators. Our study provides a baseline to manage the thermal environment of wild and rewilded populations of an important island ecosystem engineer species in an era of climate change. PMID- 29468030 TI - Introgression of exotic Cervus (nippon and canadensis) into red deer (Cervus elaphus) populations in Scotland and the English Lake District. AB - Since the mid-19th century, multiple introductions of Japanese sika deer (Cervus nippon nippon) and North American wapiti (C. canadensis) have taken place in the British Isles. While wapiti have generally been unsuccessful, sika have been very successful, especially in Scotland where they now overlap at least 40% of the range of native red deer (C. elaphus). Hybridization between these two species and red deer has been demonstrated in captivity and in the wild. Using a panel of 22 microsatellite loci that are highly diagnostic between red deer and sika, and moderately diagnostic between red deer and wapiti, we investigated the extent of introgression between these species in 2,943 deer sampled from around Scotland and from the English Lake District using the Bayesian clustering software STRUCTURE. We also used a diagnostic mitochondrial marker for red deer and sika. Our survey extends previous studies indicating little introgression of wapiti nuclear alleles into red deer, in particular in Northern Scotland, Kintyre, and the Lake District. We found a new area of extensive sika introgression in South Kintyre. In the North Highlands, we show for the first time geographically scattered evidence of past hybridization followed by extensive backcrossing, including one red-like individual with sika introgression, two sika-like individuals with red deer introgression, and six individuals that were apparently pure sika at the nuclear markers assessed but which carried red deer mitochondria. However, there has not been a collapse of assortative mating in this region. Similarly, in the English Lake District red deer, we found only traces of past sika introgression. No sika alleles were detected in the Central Highlands or the Hebridean red deer refugia. We make suggestions for management to prevent further spread of sika alleles into red deer and vice versa. PMID- 29468031 TI - Reproduction of parasitic mites Varroa destructor in original and new honeybee hosts. AB - The ectoparasitic mite, Varroa destructor, shifted host from the eastern honeybee, Apis cerana, to the western honeybee, Apis mellifera. Whereas the original host survives infestations by this parasite, they are lethal to colonies of its new host. Here, we investigated a population of A. cerana naturally infested by the V. destructor Korea haplotype that gave rise to the globally invasive mite lineage. Our aim was to better characterize traits that allow for the survival of the original host to infestations by this particular mite haplotype. A known major trait of resistance is the lack of mite reproduction on worker brood in A. cerana. We show that this trait is neither due to a lack of host attractiveness nor of reproduction initiation by the parasite. However, successful mite reproduction was prevented by abnormal host development. Adult A. cerana workers recognized this state and removed hosts and parasites, which greatly affected the fitness of the parasite. These results confirm and complete previous observations of brood susceptibility to infestation in other honeybee host populations, provide new insights into the coevolution between hosts and parasites in this system, and may contribute to mitigating the large-scale colony losses of A. mellifera due to V. destructor. PMID- 29468032 TI - Female mate choice of male signals is unlikely to promote ecological adaptation in Enchenopa treehoppers (Hemiptera: Membracidae). AB - A key question in speciation research is how ecological and sexual divergence arise and interact. We tested the hypothesis that mate choice causes local adaptation and ecological divergence using the rationale that the performance~signal trait relationship should parallel the attractiveness~signal trait relationship. We used female fecundity as a measure of ecological performance. We used a species in the Enchenopa binotata treehopper complex, wherein speciation involves adaptation to novel environments and divergence in sexual communication. We used a full-sibling, split-family rearing design to estimate genetic correlations (rG) between fecundity and signal traits, and compared those relationships against population-level mate preferences for the signal traits. Animal model estimates for rG between female fecundity and male signal traits overlapped zero-rejecting the hypothesis-but could reflect sample size limitations. The magnitude of rG correlated with the strength of the mate preferences for the corresponding signal traits, especially for signal frequency, which has the strongest mate preference and the most divergence in the complex. However, signal frequencies favored by the population-level mate preference are not associated with high fecundity. Therefore, mate preferences do not appear to have been selected to favor high-performance genotypes. Our findings suggest that ecological and sexual divergence may arise separately, but reinforce each other, during speciation. PMID- 29468033 TI - Recolonizing gray wolves increase parasite infection risk in their prey. AB - The recent recolonization of Central Europe by the European gray wolf (Canis lupus) provides an opportunity to study the dynamics of parasite transmission for cases when a definitive host returns after a phase of local extinction. We investigated whether a newly established wolf population increased the prevalence of those parasites in ungulate intermediate hosts representing wolf prey, whether some parasite species are particularly well adapted to wolves, and the potential basis for such adaptations. We recorded Sarcocystis species richness in wolves and Sarcocystis prevalence in ungulates harvested in study sites with and without permanent wolf presence in Germany using microscopy and DNA metabarcoding. Sarcocystis prevalence in red deer (Cervus elaphus) was significantly higher in wolf areas (79.7%) than in control areas (26.3%) but not in roe deer (Capreolus capreolus) (97.2% vs. 90.4%) or wild boar (Sus scrofa) (82.8% vs. 64.9%). Of 11 Sarcocystis species, Sarcocystis taeniata and Sarcocystis grueneri occurred more often in wolves than expected from the Sarcocystis infection patterns of ungulate prey. Both Sarcocystis species showed a higher increase in prevalence in ungulates in wolf areas than other Sarcocystis species, suggesting that they are particularly well adapted to wolves, and are examples of "wolf specialists". Sarcocystis species richness in wolves was significantly higher in pups than in adults. "Wolf specialists" persisted during wolf maturation. The results of this study demonstrate that (1) predator-prey interactions influence parasite prevalence, if both predator and prey are part of the parasite life cycle, (2) mesopredators do not necessarily replace the apex predator in parasite transmission dynamics for particular parasites of which the apex predator is the definitive host, even if meso- and apex predators were from the same taxonomic family (here: Canidae, e.g., red foxes Vulpes vulpes), and (3) age-dependent immune maturation contributes to the control of protozoan infection in wolves. PMID- 29468034 TI - Frequency and intensity of facilitation reveal opposing patterns along a stress gradient. AB - Disentangling the different processes structuring ecological communities is a long-standing challenge. In species-rich ecosystems, most emphasis has so far been given to environmental filtering and competition processes, while facilitative interactions between species remain insufficiently studied. Here, we propose an analysis framework that not only allows for identifying pairs of facilitating and facilitated species, but also estimates the strength of facilitation and its variation along environmental gradients. Our framework combines the analysis of both co-occurrence and co-abundance patterns using a moving window approach along environmental gradients to control for potentially confounding effects of environmental filtering in the co-abundance analysis. We first validate our new approach against community assembly simulations, and exemplify its potential on a large 1,134 plant community plots dataset. Our results generally show that facilitation intensity was strongest under cold stress, whereas the proportion of facilitating and facilitated species was higher under drought stress. Moreover, the functional distance between individual facilitated species and their facilitating species significantly changed along the temperature-moisture gradient, and seemed to influence facilitation intensity, although no general positive or general negative trend was discernible among species. The main advantages of our robust framework are as follows: It enables detecting facilitating and facilitated species in species-rich systems, and it allows identifying the directionality and intensity of facilitation in species pairs as well as its variation across long environmental gradients. It thus opens numerous opportunities for incorporating functional (and phylogenetic) information in the analysis of facilitation patterns. Our case study indicated high complexity in facilitative interactions across the stress gradient and revealed new evidence that facilitation, similarly to competition, can operate between functionally similar and dissimilar species. Extending the analyses to other taxa and ecosystems will foster our understanding how complex interspecific interactions promote biodiversity. PMID- 29468035 TI - Cryptic species and parallel genetic structuring in Lethrinid fish: Implications for conservation and management in the southwest Indian Ocean. AB - Analysis of genetic variation can provide insights into ecological and evolutionary diversification which, for commercially harvested species, can also be relevant to the implementation of spatial management strategies and sustainability. In comparison with other marine biodiversity hot spots, there has been less genetic research on the fauna of the southwest Indian Ocean (SWIO). This is epitomized by the lack of information for lethrinid fish, which support socioeconomically important fisheries in the region. This study combines comparative phylogeographic and population genetic analyses with ecological niche modeling to investigate historical and contemporary population dynamics of two species of emperor fish (Lethrinus mahsena and Lethrinus harak) across the SWIO. Both species shared similarly shallow phylogeographic patterns and modeled historical (LGM) habitat occupancies. For both species, allele frequency and kinship analyses of microsatellite variation revealed highly significant structure with no clear geographical pattern and nonrandom genetic relatedness among individuals within samples. The genetic patterns for both species indicate recurrent processes within the region that prevent genetic mixing, at least on timescales of interest to fishery managers, and the potential roles of recruitment variability and population isolation are discussed in light of biological and environmental information. This consistency in both historical and recurrent population processes indicates that the use of model species may be valuable in management initiatives with finite resources to predict population structure, at least in cases wherein biogeographic and ecological differences between taxa are minimized. Paradoxically, mtDNA sequencing and microsatellite analysis of samples from the Seychelles revealed a potential cryptic species occurring in sympatry with, and seemingly morphologically identical to, L. mahsena. BLAST results point to the likely misidentification of species and incongruence between voucher specimens, DNA barcodes, and taxonomy within the group, which highlights the utility and necessity of genetic approaches to characterize baseline biodiversity in the region before such model-based methods are employed. PMID- 29468036 TI - Wrong, but useful: regional species distribution models may not be improved by range-wide data under biased sampling. AB - Species distribution modeling (SDM) is an essential method in ecology and conservation. SDMs are often calibrated within one country's borders, typically along a limited environmental gradient with biased and incomplete data, making the quality of these models questionable. In this study, we evaluated how adequate are national presence-only data for calibrating regional SDMs. We trained SDMs for Egyptian bat species at two different scales: only within Egypt and at a species-specific global extent. We used two modeling algorithms: Maxent and elastic net, both under the point-process modeling framework. For each modeling algorithm, we measured the congruence of the predictions of global and regional models for Egypt, assuming that the lower the congruence, the lower the appropriateness of the Egyptian dataset to describe the species' niche. We inspected the effect of incorporating predictions from global models as additional predictor ("prior") to regional models, and quantified the improvement in terms of AUC and the congruence between regional models run with and without priors. Moreover, we analyzed predictive performance improvements after correction for sampling bias at both scales. On average, predictions from global and regional models in Egypt only weakly concur. Collectively, the use of priors did not lead to much improvement: similar AUC and high congruence between regional models calibrated with and without priors. Correction for sampling bias led to higher model performance, whatever prior used, making the use of priors less pronounced. Under biased and incomplete sampling, the use of global bats data did not improve regional model performance. Without enough bias-free regional data, we cannot objectively identify the actual improvement of regional models after incorporating information from the global niche. However, we still believe in great potential for global model predictions to guide future surveys and improve regional sampling in data-poor regions. PMID- 29468037 TI - Single-nucleotide polymorphism discovery and panel characterization in the African forest elephant. AB - The continuing decline in forest elephant (Loxodonta cyclotis) numbers due to poaching and habitat reduction is driving the search for new tools to inform management and conservation. For dense rainforest species, basic ecological data on populations and threats can be challenging and expensive to collect, impeding conservation action in the field. As such, genetic monitoring is being increasingly implemented to complement or replace more burdensome field techniques. Single-nucleotide polymorphisms (SNPs) are particularly cost effective and informative markers that can be used for a range of practical applications, including population census, assessment of human impact on social and genetic structure, and investigation of the illegal wildlife trade. SNP resources for elephants are scarce, but next-generation sequencing provides the opportunity for rapid, inexpensive generation of SNP markers in nonmodel species. Here, we sourced forest elephant DNA from 23 samples collected from 10 locations within Gabon, Central Africa, and applied double-digest restriction-site associated DNA (ddRAD) sequencing to discover 31,851 tags containing SNPs that were reduced to a set of 1,365 high-quality candidate SNP markers. A subset of 115 candidate SNPs was then selected for assay design and validation using 56 additional samples. Genotyping resulted in a high conversion rate (93%) and a low per allele error rate (0.07%). This study provides the first panel of 107 validated SNP markers for forest elephants. This resource presents great potential for new genetic tools to produce reliable data and underpin a step change in conservation policies for this elusive species. PMID- 29468038 TI - Functional trade-offs and the phylogenetic dispersion of seed traits in a biodiversity hotspot of the Mountains of Southwest China. AB - The diversity of traits associated with plant regeneration is often shaped by functional trade-offs where plants typically do not excel at every function because resources allocated to one function cannot be allocated to another. By analyzing correlations among seed traits, empirical studies have shown that there is a trade-off between seedling development and the occupation of new habitats, although only a small range of taxa have been tested; whether such trade-off exists in a biodiverse and complex landscape remains unclear. Here, we amassed seed trait data of 1,119 species from a biodiversity hotspot of the Mountains of Southwest China and analyzed the relationship between seed mass and the number of seeds and between seed mass and time to germination. Our results showed that seed mass was negatively correlated with seed number but positively correlated with time to germination. The same trend was found regardless of variation in life form and phylogenetic conservatism. Furthermore, the relation between seed mass and other seed traits was randomly dispersed across the phylogeny at both the order and family levels. Collectively, results suggest that there is a functional trade-off between seedling development and new habitat occupation for seed plants in this region. Larger seeds tend to produce fewer seedlings but with greater fitness compared to those produced by smaller seeds, whereas smaller seeds tend to have a larger number of seeds that germinate faster compared to large-seeded species. Apart from genetic constraints, species that produce large seeds will succeed in sites where resource availability is low, whereas species with high colonization ability (those that produce a high number of seeds per fruit) will succeed in new niches. This study provides a mechanistic explanation for the relatively high levels of plant diversity currently found in a heterogeneous region of the Mountains of Southwest China. PMID- 29468039 TI - Differences among six woody perennials native to Northern Europe in their level of genetic differentiation and adaptive potential at fine local scale. AB - The ability of perennial species to adapt their phenology to present and future temperature conditions is important for their ability to retain high fitness compared to other competing plant species, pests, and pathogens. Many transplanting studies with forest tree species have previously reported substantial genetic differentiation among populations within their native range. However, the question of "how local is local" is still highly debated in conservation biology because studies on genetic patterns of variation within and among populations at the local scale are limited and scattered. In this study, we compare the level of genetic differentiation among populations of six different perennial plant species based on their variation in spring flushing. We assess the level of additive genetic variation present within the local population. For all six species, we find significant differentiation among populations from sites with mean annual temperature ranging between 7.4 degrees C and 8.4 degrees C. The observed variation can only be partly explained by the climate at the site of origin. Most clear relationship between early flushing and higher average spring temperature is observed for the three wind-pollinated species in the study, while the relations are much less clear for the three insect-pollinated species. This supports that pollination system can influence the balance between genetic drift and natural selection and thereby influence the level of local adaptation in long lived species. On the positive side, we find that the native populations of woody plant species have maintained high levels of additive genetic variation in spring phenology, although this also differs substantially among the six studied species. PMID- 29468040 TI - Dominance of Endozoicomonas bacteria throughout coral bleaching and mortality suggests structural inflexibility of the Pocillopora verrucosa microbiome. AB - The importance of Symbiodinium algal endosymbionts and a diverse suite of bacteria for coral holobiont health and functioning are widely acknowledged. Yet, we know surprisingly little about microbial community dynamics and the stability of host-microbe associations under adverse environmental conditions. To gain insight into the stability of coral host-microbe associations and holobiont structure, we assessed changes in the community structure of Symbiodinium and bacteria associated with the coral Pocillopora verrucosa under excess organic nutrient conditions. Pocillopora-associated microbial communities were monitored over 14 days in two independent experiments. We assessed the effect of excess dissolved organic nitrogen (DON) and excess dissolved organic carbon (DOC). Exposure to excess nutrients rapidly affected coral health, resulting in two distinct stress phenotypes: coral bleaching under excess DOC and severe tissue sloughing (>90% tissue loss resulting in host mortality) under excess DON. These phenotypes were accompanied by structural changes in the Symbiodinium community. In contrast, the associated bacterial community remained remarkably stable and was dominated by two Endozoicomonas phylotypes, comprising on average 90% of 16S rRNA gene sequences. This dominance of Endozoicomonas even under conditions of coral bleaching and mortality suggests the bacterial community of P. verrucosa may be rather inflexible and thereby unable to respond or acclimatize to rapid changes in the environment, contrary to what was previously observed in other corals. In this light, our results suggest that coral holobionts might occupy structural landscapes ranging from a highly flexible to a rather inflexible composition with consequences for their ability to respond to environmental change. PMID- 29468041 TI - Genome-wide comparisons reveal a clinal species pattern within a holobenthic octopod-the Australian Southern blue-ringed octopus, Hapalochlaena maculosa (Cephalopoda: Octopodidae). AB - The southern blue-ringed octopus, Hapalochlaena maculosa (Hoyle, 1883) lacks a planktonic dispersal phase, yet ranges across Australia's southern coastline. This species' brief and holobenthic life history suggests gene flow might be limited, leaving distant populations prone to strong genetic divergence. This study used 17,523 genome-wide SNP loci to investigate genetic structuring and local adaptation patterns of H. maculosa among eight sampling sites along its reported range. Within sites, interrelatedness was very high, consistent with the limited dispersal of this taxon. However, inbreeding coefficients were proportionally lower among sites where substructuring was not detected, suggesting H. maculosa might possess a mechanism for inbreeding avoidance. Genetic divergence was extremely high among all sites, with the greatest divergence observed between both ends of the distribution, Fremantle, WA, and Stanley, TAS. Genetic distances closely followed an isolation by geographic distance pattern. Outlier analyses revealed distinct selection signatures at all sites, with the strongest divergence reported between Fremantle and the other Western Australian sites. Phylogenetic reconstructions using the described sister taxon H. fasciata (Hoyle, 1886) further supported that the genetic divergence between distal H. maculosa sites in this study was equivalent to that of between established heterospecifics within this genus. However, it is advocated that taxonomic delineations within this species should be made with caution. These data indicate that H. maculosa forms a clinal species pattern across its geographic range, with gene flow present through allele sharing between adjacent populations. Morphological investigations are recommended for a robust resolution of the taxonomic identity and ecotype boundaries of this species. PMID- 29468042 TI - Influence of damming on anuran species richness in riparian areas: A test of the serial discontinuity concept. AB - Almost all large rivers worldwide are fragmented by dams, and their impacts have been modeled using the serial discontinuity concept (SDC), a series of predictions regarding responses of key biotic and abiotic variables. We evaluated the effects of damming on anuran communities along a 245-km river corridor by conducting repeated, time-constrained anuran calling surveys at 42 locations along the Broad and Pacolet Rivers in South Carolina, USA. Using a hierarchical Bayesian analysis, we test the biodiversity prediction of the SDC (modified for floodplain rivers) by evaluating anuran occupancy and species diversity relative to dams and degree of urbanized land use. The mean response of the anuran community indicated that occupancy and species richness were maximized when sites were farther downstream from dams. Sites at the farthest distances downstream of dams (47.5 km) had an estimated ~3 more species than those just below dams. Similarly, species-specific occupancy estimates showed a trend of higher occupancy downstream from dams. Therefore, using empirical estimation within the context of a 245-km river riparian landscape, our study supports SDC predictions for a meandering river. We demonstrate that with increasing distance downstream from dams, riparian anuran communities have higher species richness. Reduced species richness immediately downstream of dams is likely driven by alterations in flow regime that reduce or eliminate flows which sustain riparian wetlands that serve as anuran breeding habitat. Therefore, to maintain anuran biodiversity, we suggest that flow regulation should be managed to ensure water releases inundate riparian wetlands during amphibian breeding seasons and aseasonal releases, which can displace adults, larvae, and eggs, are avoided. These outcomes could be achieved by emulating pre-dam seasonal discharge data, mirroring discharge of an undammed tributary within the focal watershed, or by basing real-time flow releases on current environmental conditions. PMID- 29468043 TI - The strength of negative plant-soil feedback increases from the intraspecific to the interspecific and the functional group level. AB - One of the processes that may play a key role in plant species coexistence and ecosystem functioning is plant-soil feedback, the effect of plants on associated soil communities and the resulting feedback on plant performance. Plant-soil feedback at the interspecific level (comparing growth on own soil with growth on soil from different species) has been studied extensively, while plant-soil feedback at the intraspecific level (comparing growth on own soil with growth on soil from different accessions within a species) has only recently gained attention. Very few studies have investigated the direction and strength of feedback among different taxonomic levels, and initial results have been inconclusive, discussing phylogeny, and morphology as possible determinants. To test our hypotheses that the strength of negative feedback on plant performance increases with increasing taxonomic level and that this relationship is explained by morphological similarities, we conducted a greenhouse experiment using species assigned to three taxonomic levels (intraspecific, interspecific, and functional group level). We measured certain fitness-related aboveground traits and used them along literature-derived traits to determine the influence of morphological similarities on the strength and direction of the feedback. We found that the average strength of negative feedback increased from the intraspecific over the interspecific to the functional group level. However, individual accessions and species differed in the direction and strength of the feedback. None of our results could be explained by morphological dissimilarities or individual traits. Synthesis. Our results indicate that negative plant-soil feedback is stronger if the involved plants belong to more distantly related species. We conclude that the taxonomic level is an important factor in the maintenance of plant coexistence with plant-soil feedback as a potential stabilizing mechanism and should be addressed explicitly in coexistence research, while the traits considered here seem to play a minor role. PMID- 29468044 TI - Low rates of hybridization between European wildcats and domestic cats in a human dominated landscape. AB - Hybridization between wild species and their domestic congeners is considered a major threat for wildlife conservation. Genetic integrity of the European wildcat, for instance, is a concern as they are outnumbered by domestic cats by several orders of magnitude throughout its range. We genotyped 1,071 individual wildcat samples obtained from hair traps and roadkills collected across the highly fragmented forests of western Central Europe, in Germany and Luxembourg, to assess domestic cat introgression in wildcats in human-dominated landscapes. Analyses using a panel of 75 autosomal SNPs suggested a low hybridization rate, with 3.5% of wildcat individuals being categorized as F1, F2, or backcrosses to either parental taxon. We report that results based on a set of SNPs were more consistent than on a set of 14 microsatellite markers, showed higher accuracy to detect hybrids and their class in simulation analyses, and were less affected by underlying population structure. Our results strongly suggest that very high hybridization rates previously reported for Central Europe may be partly due to inadequate choice of markers and/or sampling design. Our study documents that an adequately selected SNP panel for hybrid detection may be used as an alternative to commonly applied microsatellite markers, including studies relying on noninvasively collected samples. In addition, our finding of overall low hybridization rates in Central European wildcats provides an example of successful wildlife coexistence in human-dominated, fragmented landscapes. PMID- 29468045 TI - An interaction-driven cannibalistic reaction norm. AB - Cannibalism is induced in larval-stage populations of the Hokkaido salamander, Hynobius retardatus, under the control of a cannibalism reaction norm. Here, I examined phenotypic expression under the cannibalism reaction norm, and how the induction of a cannibalistic morph under the norm leads to populational morphological diversification. I conducted a set of experiments in which density was manipulated to be either low or high. In the high-density treatment, the populations become dimorphic with some individuals developing into the cannibal morph type. I performed an exploratory analysis based on geometric morphometrics and showed that shape characteristics differed between not only cannibal and noncannibal morph types in the high-density treatment but also between those morph types and the solitary morph type in the low-density treatment. Size and shape of cannibal and noncannibal individuals were found to be located at either end of a continuum of expression following a unique size-shape integration rule that was different from the rule governing the size and shape variations of the solitary morph type. This result implies that the high-density-driven inducible morphology of an individual is governed by a common integration rule during the development of dimorphism under the control of the cannibalism reaction norm. Phenotypic expression under the cannibalism reaction norm is driven not only by population density but also by social interactions among the members of a population: variation in the populational expression of dimorphism is associated with contingent social interaction events among population members. The induced cannibalistic morph thus reflects not only by contest-type exploitative competition but also interference competition.

AB - The gypsy moth-Lymantria dispar (Linnaeus)-is a worldwide forest defoliator and is of two types: the European gypsy moth and the Asian gypsy moth. Because of multiple invasions of the Asian gypsy moth, the North American Plant Protection Organization officially approved Regional Standards for Phytosanitary Measures No. 33. Accordingly, special quarantine measures have been implemented for 30 special focused ports in the epidemic areas of the Asian gypsy moth, including China, which has imposed great inconvenience on export trade. The Asian gypsy moth and its related species (i.e., Lymantria monocha and Lymantria xylina) intercepted at ports are usually at different life stages, making their identification difficult. Furthermore, Port quarantine requires speedy clearance. As such, it is difficult to identify the Asian gypsy moth and its related species only by their morphological characteristics in a speedy measure. Therefore, this study aimed to use molecular biology technology to rapidly identify the Asian gypsy moth and its related species based on the consistency of mitochondrial DNA in different life stages. We designed 10 pairs of specific primers from different fragments of the Asian gypsy moth and its related species, and their detection sensitivity met the need for rapid identification. In addition, we determined the optimal polymerase chain reaction amplification temperature of the 10 pairs of specific primers, including three pairs of specific primers for the Asian gypsy moth (L. dispar asiatic), four pairs of specific primers for the nun moth (L. monocha), and three pairs of specific primers for the casuarina moth (L. xylina). In conclusion, using our designed primers, direct rapid identification of the Asian gypsy moth and its related species is possible, and this advancement can help improve export trade in China.

AB - The KwaZulu-Natal yellowfish (Labeobarbus natalensis) is an abundant cyprinid, endemic to KwaZulu-Natal Province, South Africa. In this study, we developed a single-nucleotide polymorphism (SNP) dataset from double-digest restriction site associated DNA (ddRAD) sequencing of samples across the distribution. We addressed several hidden challenges, primarily focusing on proper filtering of RAD data and selecting optimal parameters for data processing in polyploid lineages. We used the resulting high-quality SNP dataset to investigate the population genetic structure of L. natalensis. A small number of mitochondrial markers present in these data had disproportionate influence on the recovered genetic structure. The presence of singleton SNPs also confounded genetic structure. We found a well-supported division into northern and southern lineages, with further subdivision into five populations, one of which reflects north-south admixture. Approximate Bayesian Computation scenario testing supported a scenario where an ancestral population diverged into northern and southern lineages, which then diverged to yield the current five populations. All river systems showed similar levels of genetic diversity, which appears unrelated to drainage system size. Nucleotide diversity was highest in the smallest river system, the Mbokodweni, which, together with adjacent small coastal systems, should be considered as a key catchment for conservation. PMID- 29468048 TI - A novel sperm adaptation to evolutionary constraints on reproduction: Pre ejaculatory sperm activation in the beach spawning capelin (Osmeridae). AB - Reproduction of external fertilizing vertebrates is typically constrained to either fresh or salt water, not both. For all studied amphibians and fishes, this constraint includes immotile sperm that are activated after ejaculation only by the specific chemistry of the fertilizing medium in which the species evolved (fresh, brackish, or salt water). No amphibians can reproduce in the sea. Although diadromous fishes may migrate between salt and fresh water, they are shackled to their natal environment for spawning in part because of sperm activation. Here, we report for the first time among all documented external fertilizing vertebrates, that in the absence of any external media, sperm are motile at ejaculation in a marine spawning fish (Osmeridae, capelin, Mallotus villosus). To illuminate why, we evaluated sperm behavior at different salinities in M. villosus as well as the related freshwater spawning anadromous rainbow smelt (Osmerus mordax). Surprisingly, sperm performance was superior in fresh water for both species. M. villosus spend their entire life at sea but our results show that their sperm are deactivated by sea water, suggesting a freshwater ancestry. By circumventing constraining water chemistry, we interpret the unique pre-ejaculatory sperm activation in this species as a novel adaptation that enables fertilization in the marine environment. These findings also contribute to understanding the persistence of anadromy, despite great energetic costs to adult fishes. PMID- 29468049 TI - Sea ice meiofauna distribution on local to pan-Arctic scales. AB - Arctic sea ice provides microhabitats for biota that inhabit the liquid-filled network of brine channels and the ice-water interface. We used meta-analysis of 23 published and unpublished datasets comprising 721 ice cores to synthesize the variability in composition and abundance of sea ice meiofauna at spatial scales ranging from within a single ice core to pan-Arctic and seasonal scales. Two thirds of meiofauna individuals occurred in the bottom 10 cm of the ice. Locally, replicate cores taken within meters of each other were broadly similar in meiofauna composition and abundance, while those a few km apart varied more; 75% of variation was explained by station. At the regional scale (Bering Sea first year ice), meiofauna abundance varied over two orders of magnitude. At the pan Arctic scale, the same phyla were found across the region, with taxa that have resting stages or tolerance to extreme conditions (e.g., nematodes and rotifers) dominating abundances. Meroplankton, however, was restricted to nearshore locations and landfast sea ice. Light availability, ice thickness, and distance from land were significant predictor variables for community composition on different scales. On a seasonal scale, abundances varied broadly for all taxa and in relation to the annual ice algal bloom cycle in both landfast and pack ice. Documentation of ice biota composition, abundance, and natural variability is critical for evaluating responses to decline in Arctic sea ice. Consistent methodology and protocols must be established for comparability of meiofauna monitoring across the Arctic. We recommend to (1) increase taxonomic resolution of sea ice meiofauna, (2) focus sampling on times of peak abundance when seasonal sampling is impossible, (3) include the bottom 30 cm of ice cores rather than only bottom 10 cm, (4) preserve specimens for molecular analysis to improve taxonomic resolution, and (5) formulate a trait-based framework that relates to ecosystem functioning. PMID- 29468050 TI - Functional macronutritional generalism in a large omnivore, the brown bear. AB - We combine a recently developed framework for describing dietary generalism with compositional data analysis to examine patterns of omnivory in a large widely distributed mammal. Using the brown bear (Ursus arctos) as a model species, we collected and analyzed data from the literature to estimate the proportions of macronutrients (protein, carbohydrate, and lipid) in the diets of bear populations. Across their range, bears consumed a diversity of foods that resulted in annual population diets that varied in macronutrient proportions, suggesting a wide fundamental macronutrient niche. The variance matrix of pairwise macronutrient log-ratios indicated that the most variable macronutrient among diets was carbohydrate, while protein and lipid were more proportional or codependent (i.e., relatively more constant log-ratios). Populations that consumed anthropogenic foods, such agricultural crops and supplementary feed (e.g., corn), had a higher geometric mean proportion of carbohydrate, and lower proportion of protein, in annual diets. Seasonally, mean diets were lower in protein and higher in carbohydrate, during autumn compared to spring. Populations with anthropogenic subsidies, however, had higher mean proportions of carbohydrate and lower protein, across seasons compared to populations with natural diets. Proportions of macronutrients similar to those selected in experiments by captive brown bears, and which optimized primarily fat mass gain, were observed among hyperphagic prehibernation autumn diets. However, the majority of these were from populations consuming anthropogenic foods, while diets of natural populations were more variable and typically higher in protein. Some anthropogenic diets were close to the proportions selected by captive bears during summer. Our results suggest that omnivory in brown bears is a functional adaptation enabling them to occupy a diverse range of habitats and tolerate variation in the nutritional composition and availability of food resources. Furthermore, we show that populations consuming human-sourced foods have different dietary macronutrient proportions relative to populations with natural diets. PMID- 29468051 TI - The knowledge, attitudes and practices of doctors regarding antibiotic resistance at a tertiary care institution in the Caribbean. AB - Background: Antibiotic resistance (ABR) is a serious threat that requires coordinated global intervention to prevent its spread. There is limited data from the English-speaking Caribbean. Methods: As part of a national programme to address antibiotic resistance in Jamaica, a survey of the knowledge, attitudes and antibiotic prescribing practices of Jamaican physicians was conducted using a 32-item self-administered questionnaire. Results: Of the eight hundred physicians targeted, 87% responded. The majority thought the problem of resistance very important globally (82%), less nationally (73%) and even less (53%) in personal practices. Hospital physicians were more likely to consider antibiotic resistance important in their practice compared to those in outpatient practice or both (p < 0.001). Composite knowledge scores were generated and considered good if scored > 80%, average if 60-79% and poor if < 60%. Most had good knowledge of factors preventing resistance (83%) and resistance inducing potential of specific antibiotics (59%), but only average knowledge of factors contributing to resistance (57%). Knowledge of preventative factors was highest in females (p = 0.004), those with postgraduate training (p = 0.001) and those > four years post graduation (p = 0.03). Empiric therapy was often directed by international guidelines and cultures were not routinely done. Limited laboratory and human resources were identified as challenges. Conclusion: Physicians in this study were aware of the problem of ABR, but downplayed its significance nationally and personally. These results will guide a national antibiotic stewardship programme. PMID- 29468052 TI - Prevalence of Staphylococcus spp. nasal colonization among doctors of podiatric medicine and associated risk factors in Spain. AB - Background: This study aimed to estimate the prevalence of methicillin susceptible and -resistant Staphylococcus aureus (MSSA and MRSA) and methicillin resistant Staphylococcus epidermidis (MRSE) nasopharyngeal carriage among Doctors of Podiatric Medicine (Podiatrists) and to determine the potential risk factors. Methods: A cross-sectional study was carried out in 2016-2017 among 239 podiatrists in Spain. The presence of MSSA, MRSA, and MRSE was determined by microbiological analysis of nasal exudate and antimicrobial susceptibility was determined. Each podiatrist completed a questionnaire. The questionnaire comprised various parameters such as sex, age, podiatry experience duration, underlying diseases, prior antibiotic treatment, hospitalization during the last year, and use of a protective mask, an aspiration system, or gloves. Results: The prevalence of MSSA, MRSA, and MRSE was 23.0%, 1.3%, and 23.8%, respectively. The MSSA prevalence was higher among podiatrists who did not use an aspiration system (32.3%) compared to those who did (19.3%; p = 0.0305), and among podiatrists with respiratory diseases (36.8%) compared to those without (20.8%; p = 0.0272). The MRSE prevalence was higher among men (33.7%) compared to women (8.6%; p = 0.0089), podiatrists aged >=50 (38.5%) compared to <=35 (17.8%; p = 0.0101), and podiatrists with >=15 (39.3%) compared to <=5 years of podiatry experience (12.5%; p = 0.0015). Among the S. aureus strains, 84.5% were resistant to penicillin, 22.4% to erythromycin, 20.7% to clindamycin, and 12.7% to mupirocin. The MRSE strains were resistant to penicillin (93.0%), erythromycin (78.9%), and mupirocin (73.7%). Conclusions: The prevalence of S. aureus and S. epidermidis nasal carriage is low among Spanish podiatrists compared to other health professionals. PMID- 29468053 TI - APSIC guidelines for disinfection and sterilization of instruments in health care facilities. AB - Background: The Asia Pacific Society of Infection Control launched its revised Guidelines for Disinfection and Sterilization of Instruments in Health Care Facilities in February 2017. This document describes the guidelines and recommendations for the reprocessing of instruments in healthcare setting. It aims to highlight practical recommendations in a concise format designed to assist healthcare facilities at Asia Pacific region in achieving high standards in sterilization and disinfection. Method: The guidelines were revised by an appointed workgroup comprising experts in the Asia Pacific region, following reviews of previously published guidelines and recommendations relevant to each section. Results: It recommends the centralization of reprocessing, training of all staff with annual competency assessment, verification of cleaning, continual monitoring of reprocessing procedures to ensure their quality and a corporate strategy for dealing with single-use and single-patient use medical equipment/devices. Detailed recommendations are also given with respect to reprocessing of endoscopes. Close working with the Infection Prevention & Control department is also recommended where decisions related to reprocessing medical equipment/devices are to be made. Conclusions: Sterilization facilities should aim for excellence in practices as this is part of patient safety. The guidelines that come with a checklist help service providers identify gaps for improvement to reach this goal. PMID- 29468054 TI - In vitro activity of ivermectin against Staphylococcus aureus clinical isolates. AB - Background: Ivermectin is an endectocide against many parasites. Though being a macrocyclic lactone, its activity against bacteria has been less known, possibly due to the fact that micromolar concentrations at tissue levels are required to achieve a therapeutic effect. Among pathogenic bacteria of major medical significance, Staphylococcus aureus cause a number of diseases in a wide variety of hosts including humans and animals. It has been attributed as one of the most pathogenic organisms. The emergence of methicillin resistance has made the treatment of S. aureus even more difficult as it is now resistant to most of the available antibiotics. Thus, search for alternate anti-staphylococcal agents requires immediate attention. Methods: Twenty-one clinical isolates of S. aureus were isolated from bovine milk collected from Lahore and Faisalabad Pakistan. Different anthelmintics including levamisole, albendazole and ivermectin were tested against S. aureus to determine their minimum inhibitory concentrations. This was followed-up by growth curve analysis, spot assay and time-kill kinetics. Results: The results showed that ivermectin but not levamisole or albendazole exhibited a potent anti-staphylococcal activity at the concentrations of 6.25 and 12.5 MUg/ml against two isolates. Interestingly, one of the isolate was sensitive while the other was resistant to methicillin/cefoxitin. Conclusions: Our novel findings indicate that ivermectin has an anti-bacterial effect against certain S. aureus isolates. However, to comprehend why ivermectin did not inhibit the growth of all Staphylococci needs further investigation. Nevertheless, we have extended the broad range of known pharmacological effects of ivermectin. As pharmacology and toxicology of ivermectin are well known, its further development as an anti staphylococcal agent is potentially appealing. PMID- 29468055 TI - Comparison of governance approaches for the control of antimicrobial resistance: Analysis of three European countries. AB - Policy makers and governments are calling for coordination to address the crisis emerging from the ineffectiveness of current antibiotics and stagnated pipe-line of new ones - antimicrobial resistance (AMR). Wider contextual drivers and mechanisms are contributing to shifts in governance strategies in health care, but are national health system approaches aligned with strategies required to tackle antimicrobial resistance? This article provides an analysis of governance approaches within healthcare systems including: priority setting, performance monitoring and accountability for AMR prevention in three European countries: England, France and Germany. Advantages and unresolved issues from these different experiences are reported, concluding that mechanisms are needed to support partnerships between healthcare professionals and patients with democratized decision-making and accountability via collaboration. But along with this multi-stakeholder approach to governance, a balance between regulation and persuasion is needed. PMID- 29468056 TI - Implementation of universal rapid human immunodeficiency virus screening on labor and delivery. AB - Background: A case of mother to child transmission (MTCT) of HIV at a medical center in Washington, DC, resulted in the implementation of universal opt-out rapid testing of patients admitted for delivery. This article evaluates the policy's efficacy and implementation. Methods: We evaluated the implementation using the Reach, Efficacy, Adoption, Implementation, and Maintenance (RE-AIM) framework. Results: We could not evaluate decrease in MTCT rate secondary to low sample size (n = 3324) and no true-positive results. Patients not tested (n = 458) were predominately secondary to physician omission (93.7%) and were more likely to be White (p < 0.01) and older (p < 0.01). There was a negative relationship with physician omission over time. Conclusion: The policy was successfully implemented with decreasing proportions of patients not tested. Earlier inclusion of testing into standard admission orders and nurse-based approach may have expedited adoption. Given the low incidence of new HIV diagnosis in labor, we were unable to assess decrease in MTCT. PMID- 29468057 TI - Utility of convex EUS for preoperative vascular evaluation of malignant biliary tract neoplasm. AB - The aim of the present study was to examine the utility of convex endoscopic ultrasonography (EUS) for the preoperative vascular evaluation of malignant biliary tract neoplasm, by comparing EUS findings with histological findings from resected specimens. Between January 2008 and January 2016, the present study retrospectively retrieved 82 cases diagnosed with malignant biliary tract neoplasm to compare findings from convex EUS with histological findings from resected specimens. A total of four groups were defined according to the results of EUS of the hepatic artery (HA) and portal vein (PV): Group 1, hyperechoic tissue between tumor and vessel; group 2, close proximity between tumor and vessel without loss of hyperechoic tissue; group 3, tumor and vessel contiguity, with loss of hyperechoic tissue; and group 4, encasement >180 degrees . Regarding the HA, all 17 cases in groups 2 and 3 in which the tumor was close to the HA however no obvious encasement was evident, demonstrated no histological invasion, or the HA could be separated from the tumor intraoperatively. However, this was not the case for the portal vein. Of the six cases in group 3, 4 cases (66.7%) demonstrated PV invasion. Overall, convex EUS is useful for the preoperative evaluation of malignant biliary tract neoplasms, and surgery may be considered when the tumor is close to the HA on computed tomography scans, however there is no obvious encasement visualized by convex EUS. PMID- 29468058 TI - A patient with MEN1 and end-stage chronic kidney disease due to Alport syndrome: Decision making on the eligibility of transplantation. AB - Absence of neoplastic disease in the organ-recipient is required in order to allow organ transplantation. Due to its rarity, no data regarding management of patients with Multiple endocrine neoplasia type 1 (MEN1) and end-stage renal failure candidates for kidney transplantation are available. A 36 year-old man was referred to the present hospital with MEN1, with a neuroendocrine pancreatic tumor and primary hyperparathyroidism and associated Alport syndrome with end stage renal failure. The present study aimed to establish the eligibility of the patient for a kidney transplantation. The neuroendocrine tumor had been treated with duodenopancreatectomy two years earlier and hyperparathyroidism by parathyroidectomy. The review of the literature did not provide data regarding the eligibility for kidney transplantation of patients harboring a neuroendocrine pancreatic tumor in the context of MEN1. Due to the end-stage renal failure, neuroendocrine markers were unreliable and the investigation therefore relied on imaging studies, which were unremarkable. Young age, low-grade tumor, low expression of Ki67, absence of metastatic lymph nodes, onset in the setting of a MEN1 were all positive prognostic factors of the neuroendocrine tumor. Normal serum calcium ruled out persistent primary hyperparathyroidism. Overall, hemodyalisis is known to significantly reduce life expectancy. Benefits of kidney transplantation overcome the risk of neuroendocrine tumor recurrence in a young patient bearing MEN1. PMID- 29468059 TI - Oxaliplatin-induced hepatic sinusoidal obstruction syndrome in a patient with gastric cancer: A case report. AB - Oxaliplatin is a platinum-based antineoplastic agent used in cancer chemotherapy. Oxaliplatin-induced hepatic sinusoidal obstruction syndrome (HSOS) has been reported in the context of chemotherapy for liver metastasis of colorectal cancer. However, to the best of our knowledge, there is no report of oxaliplatin associated HSOS in patients with gastric cancer. The present study reported a patient with gastric cancer who received proximal gastrectomy and oxaliplatin containing chemotherapy. Contrast-enhanced computed tomography revealed that liver parenchyma appeared heterogeneous and demonstrated hypoattenuation in the portal phase. In dynamic contrast-enhanced magnetic resonance imaging, hypointense heterogeneity was demonstrated in the portal-venous phase. Pathological examination indicated distinctive multifocal sinusoidal dilatation. In conclusion, the present report indicated a case of oxaliplatin-induced HSOS in a patient with gastric cancer who received oxaliplatin-contained chemotherapy. PMID- 29468060 TI - Identification of i(X)(p10) as the sole molecular abnormality in atypical chronic myeloid leukemia evolved into acute myeloid leukemia. AB - The World Health Organization classifies atypical chronic myeloid leukemia (aCML) as a myeloproliferative/myelodisplastic hematological disorder. The primary manifestations are leukocytosis with disgranulopoiesis, absence of basophilia and/or monocytosis, splenomegaly and absence of Philadelphia chromosome or BCR/ABL fusion. Overall 50-65% of patients demonstrate karyotypic abnormalities, although no specific cytogenetic alterations have been associated with this disease. X chromosome alterations have been rarely reported in myeloid malignancies. Although Isodicentric X, idic(X)(q13) is well known in females with myelodysplastic syndromes (MDS), little data are available on X isochromosome and its pathogenetic potential in these disorders. i(X)(p10) is observed in a variety of hematologic malignancies, both myeloid and lymphoid, as a unique abnormality, as well as part of a more complex karyotype, in females and less frequently in male patients. The present report describes the first patient with aCML, with documented isolated i(X)(p10), who developed a secondary acute myeloid leukemia (sAML). PMID- 29468061 TI - Plasma interleukin-8 levels are persistently elevated for 1 month after minimally invasive colorectal resection for colorectal cancer. AB - Minimally invasive colorectal resection (MICR) for colorectal cancer (CRC) is associated with elevated levels of seven proangiogenic proteins that persist for 2-4 weeks after surgery. The proangiogenic plasma may promote tumor growth postoperatively in patients with residual cancer. To the best of our knowledge, the impact of surgery on interleukin 8 (IL-8) levels is unknown. The aim of the present study was to evaluate plasma IL-8 levels after MICR for CRC. Patients with CRC enrolled in an institutional review board-approved plasma/data bank who underwent MICR were eligible. Blood samples were taken preoperatively (preop) and at multiple postoperative (postop) time points, and were stored at -80 degrees C. Only patients for whom preop, postop day (POD) 1, POD 3 and at least 1 late postop plasma samples (POD7-34) available were enrolled. Clinical, demographical and pathological data were collected. IL-8 levels were determined via ELISA and results were reported as the mean and +/- standard deviation. The Wilcoxon signed rank test was used for analysis with P<0.05 used as the significance threshold. A total of 73 CRC patients (colon, 62%; rectal, 38%) who underwent MICR (laparoscopic-assisted, 60%; hand-assisted, 40%) were studied. The mean preop IL 8 level was 20.4+/-10.6 pg/ml. Significant elevations in plasma IL-8 levels were noted compared with preop levels on POD1 (43.1+/-38.6; n=72; P<0.0001), POD 3 (33.0+/-30.1; n=71; P<0.0001), POD7-13 (29.9+/-21.9; n=50; P<0.0001), POD14-20 (33.1+/-18.3; n=24; P=0.002), and for the POD21-27 time point (24.0+/-9.2; n=16; P=0.002). In conclusion, plasma IL-8 levels were significantly elevated from baseline for 4 weeks after MICR for CRC. In conjunction with the other proangiogenic MICR-associated blood compositional changes, increased IL-8 levels may promote tumor angiogenesis and growth postop. PMID- 29468062 TI - Characterization of oncogene suppressor marker expression in patients with submucosal gastric carcinoma. AB - The aim of the present study was to determine the clinical significance of p53 and p21ras p21wafl, p27kip1 and p16ink4a expression in cases of early gastric cancer. A total of 81 patients who had undergone gastrectomy with D2 lymphadenectomy between 1971 and 2004 were retrospectively investigated. The immunohistochemical expression of p21ras, p53, p21waf1/cip1, p27kip1 and p16ink4a in the tissues was evaluated. In normal, metaplastic and tumoral mucosa, p53 was positive in 53, 87.3, and 87.1% of the cases, respectively. In the same tissues, p21ras was positivE in 85.3, 86 and 96.8%, respectively. Positivity FOR p16ink4a was DETECTED IN 46.3, 91.1 and 86% OF THE CASES, respectively, WHEREAS p27kip1 WAS positiVE IN 60, 94.7 and 95.3%, and p21wafl/cip1 WAS positivE IN 32.4, 72.7 and 71.4% OF THE CASES, respectively. All THE tumors WERE positive for p53. Tumors with lymph node invasion presented WITH OVERexpression (+4) of p53 in 47% of the cases VS. 17% OF patients who DID not HAVE lymph node involvement. THEREFORE, higher expression of p53, p21ras and p21wafl/cip1 IN the tumor exhibited a statistically significant association with lymph node involvement. PMID- 29468063 TI - Effects of metformin on survival outcomes of pancreatic cancer patients with diabetes: A meta-analysis. AB - Pancreatic cancer risk is reduced by metformin treatment in patients with diabetes. However, the effect of metformin on pancreatic cancer overall survival is unclear. The aim of the present study was to determine the association between metformin and clinical outcomes of pancreatic cancer patients with diabetes. An electronic and manual search was conducted using PubMed, Web of Science, Medline Ovid and Cochrane Library databases between the beginning and March 31, 2017. A total of 8 studies consisting of 4,293 patients with pancreatic cancer with diabetes were included, comprising 2,033 patients who had received metformin and 2,260 patients who had not. The meta-analysis showed that metformin was associated with a relative survival benefit in pancreatic cancer patients [hazard ratio (HR), 0.81; 95% confidence interval (CI), 0.70-0.93]. These associations were also observed in subgroups of Asian countries 0.64 (95% CI, 0.52-0.80) and Western countries 0.88 (95% CI, 0.82-0.95), as well as diabetes (no indication of diabetes type). Excluding the studies considered as be prone to immortal time bias resulted in HRs (95% CIs) of 0.86 (0.69-1.07). The results of this study support the notion that the use of metformin may improve the overall survival of patients with pancreatic cancer with concurrent diabetes. However, the proposed beneficial effect of metformin on pancreatic cancer survival may be based on immortal time bias. Further carefully designed studies with high quality are warranted to confirm this efficacy. PMID- 29468064 TI - The multiple faces of Langerhans cell histiocytosis in childhood: A gentle reminder. AB - Langerhans cell histiocytosis (LCH) is a rare hematologic disorder that results from the clonal multiplication and accumulation of immature dendritic Langerhans cells. Its reported incidence rate varies, but is considered to be 2.6-8.9 per million children who are <15 years of age each year. It may affect any system or organ. The present study reported 4 pediatric LCH cases in order to highlight the heterogeneity of the initial presentation, and the pitfalls that may mislead clinicians and delay diagnosis. The clinical features, as well as the pathognomonic imaging, pathology findings and treatment options were presented. LCH may be rare, but it should always be included in the differential diagnosis of persistent eczema, unexplained skin lesions, diabetes insipidus and persistent bone pain, among others. While the debate on pathogenesis and treatment is ongoing, high index of suspicion among pediatricians, pediatric oncologists and other specialists (pathologists, dermatologists, orthopaedic surgeons, general practitioners or family physicians) is essential for early diagnosis, and optimal outcome. PMID- 29468065 TI - Neuroimaging in bulimia nervosa and binge eating disorder: a systematic review. AB - Objective: In recent decades there has been growing interest in the use of neuroimaging techniques to explore the structural and functional brain changes that take place in those with eating disorders. However, to date, the majority of research has focused on patients with anorexia nervosa. This systematic review addresses a gap in the literature by providing an examination of the published literature on the neurobiology of individuals who binge eat; specifically, individuals with bulimia nervosa (BN) and binge eating disorder (BED). Methods: A systematic review was conducted in accordance with PRISMA guidelines using PubMed, PsycInfo, Medline and Web of Science, and additional hand searches through reference lists. 1,003 papers were identified in the database search. Published studies were included if they were an original research paper written in English; studied humans only; used samples of participants with a diagnosed eating disorder characterised by recurrent binge eating; included a healthy control sample; and reported group comparisons between clinical groups and healthy control groups. Results: Thirty-two papers were included in the systematic review. Significant heterogeneity in the methods used in the included papers coupled with small sample sizes impeded the interpretation of results. Twenty-one papers utilised functional Magnetic Resonance Imaging (fMRI); seven papers utilized Magnetic Resonance Imaging (MRI) with one of these using both MRI and Positron Emission Technology (PET); three studies used Single-Photon Emission Computed Tomography (SPECT) and one study used PET only. A small number of consistent findings emerged in individuals in the acute phase of illness with BN or BED including: volume reduction and increases across a range of areas; hypoactivity in the frontostriatal circuits; and aberrant responses in the insula, amygdala, middle frontal gyrus and occipital cortex to a range of different stimuli or tasks; a link between illness severity in BN and neural changes; diminished attentional capacity and early learning; and in SPECT studies, increased rCBF in relation to disorder-related stimuli. Conclusions: Studies included in this review are heterogenous, preventing many robust conclusions from being drawn. The precise neurobiology of BN and BED remains unclear and ongoing, large-scale investigations are required. One clear finding is that illness severity, exclusively defined as the frequency of binge eating or bulimic episodes, is related to greater neural changes. The results of this review indicate additional research is required, particularly extending findings of reduced cortical volumes and diminished activity in regions associated with self-regulation (frontostriatal circuits) and further exploring responses to disorder-related stimuli in people with BN and BED. PMID- 29468066 TI - Evaluation of lipid profiles and hematological parameters in hypertensive patients: Laboratory-based cross-sectional study. AB - Introduction: Hypertension and dyslipidemia are the two coexisting and synergizing major risk factors for cardiovascular diseases. The cellular constituents of blood affect the volume and viscosity of blood, thus playing a key role in regulating blood pressure. Overweight and obesity are key determinants of adverse metabolic changes including an increase in blood pressure. The aim of this study was to evaluate lipid profiles and hematological parameters in hypertensive patients at Debre Markos Referral Hospital, Northwest Ethiopia. Methods: Laboratory-based cross-sectional study was conducted in 100 eligible hypertensive patients at the hospital. The required amount of blood was withdrawn from the patients by healthcare professionals for immediate automated laboratory analyses. Data were collected on socio-demographic factors, anthropometric measurements, blood pressure, lipid profiles, and hematological parameters. Result: The mean serum levels of triglyceride, total cholesterol, and low-density lipoprotein were significantly higher than their respective cut-off values in the hypertensive patients. Besides, 54%, 52%, 35%, and 11% of the hypertensive patients had abnormal low-density lipoprotein, total cholesterol, triglyceride, and high-density lipoprotein levels, respectively. Higher levels of low-density lipoprotein, hemoglobin, and red blood cell count were observed in the hypertensive patients whose blood pressure had been poorly controlled than the controlled ones (p < 0.05). Waist circumference had a significant positive association with the serum levels of total cholesterol and white blood cell count (p < 0.05). Conclusion: Hypertensive patients had a high prevalence of lipid profile abnormalities and poorly controlled blood pressure which synergize in accelerating other cardiovascular diseases. Some hematological parameters such as red blood cell count are also increased as do the severity of hypertension.

AB - Varicella zoster virus reactivation is a rare cause of pharyngeal dysphagia with long-term sequelae persisting in most cases. A 76-year-old immunocompetent woman presented with a 4-week history of dysphagia and dysphonia. Brain magnetic resonance imaging displayed a negative finding. Fiberoptic endoscopic evaluation of swallowing showed a severe dysphagia leading to a percutaneous gastrostomy eventually. Cerebrospinal fluid analysis revealed a lymphocytic pleocytosis and polymerase chain reaction amplified Varicella zoster virus DNA. Eight months after Acyclovir treatment and despite a persisting impairment of the recurrent laryngeal nerve, regular swallowing function was regained and percutaneous gastrostomy could be removed. PMID- 29468068 TI - A case report of thrombosed varicosities of pubic collateral veins: Ideal treatment strategy and contribution of era imaging technologies in diagnosis. AB - Collateral circulation is an alternative path occurring in case of venous or artery obstruction. This path may usually develop after primary recanalization. In our case, a 62-year-old woman presented to our Emergency Department complaining about a suprapubic swelling with a cyanotic discoloration of the overlying skin for the past 10 days for which she had been previously prescribed antibiotics. Investigation with ultrasound and contrast-enhanced computed tomography was performed. An imaging study revealed thrombosed pubic varicose collateral veins due to deep vein obstruction and occlusion of the left external iliac vein. The patient was treated with low-molecular-weight heparin, and swelling subsided gradually. Collateral veins of the abdominal wall and over the pubic tubercle are highly predictive of deep venous obstructive disease proximal to the groin level. These collaterals should never be removed, and the patient should be subjected to a diligent laboratory and imaging investigation. PMID- 29468069 TI - Utility of SOFA score, management and outcomes of sepsis in Southeast Asia: a multinational multicenter prospective observational study. AB - Background: Sepsis is a global threat but insufficiently studied in Southeast Asia. The objective was to evaluate management, outcomes, adherence to sepsis bundles, and mortality prediction of maximum Sequential Organ Failure Assessment (SOFA) scores in patients with community-acquired sepsis in Southeast Asia. Methods: We prospectively recruited hospitalized adults within 24 h of admission with community-acquired infection at nine public hospitals in Indonesia (n = 3), Thailand (n = 3), and Vietnam (n = 3). In patients with organ dysfunction (total SOFA score >= 2), we analyzed sepsis management and outcomes and evaluated mortality prediction of the SOFA scores. Organ failure was defined as the maximum SOFA score >= 3 for an individual organ system. Results: From December 2013 to December 2015, 454 adult patients presenting with community-acquired sepsis due to diverse etiologies were enrolled. Compliance with sepsis bundles within 24 h of admission was low: broad-spectrum antibiotics in 76% (344/454), >= 1500 mL fluid in 50% of patients with hypotension or lactate >= 4 mmol/L (115/231), and adrenergic agents in 71% of patients with hypotension (135/191). Three hundred and fifty-five patients (78%) were managed outside of ICUs. Ninety-nine patients (22%) died. Total SOFA score on admission of those who subsequently died was significantly higher than that of those who survived (6.7 vs. 4.6, p < 0.001). The number of organ failures showed a significant correlation with 28-day mortality, which ranged from 7% in patients without any organ failure to 47% in those with failure of at least four organs (p < 0.001). The area under the receiver operating characteristic curve of the total SOFA score for discrimination of mortality was 0.68 (95% CI 0.62-0.74). Conclusions: Community acquired sepsis in Southeast Asia due to a variety of pathogens is usually managed outside the ICU and with poor compliance to sepsis bundles. In this population, calculation of SOFA scores is feasible and SOFA scores are associated with mortality. Trial registration: ClinicalTrials.gov, NCT02157259.

PMID- 29468070 TI - Reduced alcohol-seeking in male offspring of sires exposed to alcohol self administration followed by punishment-imposed abstinence. AB - Emerging evidence has demonstrated that paternal alcohol use can modify the behavior of offspring, particularly male offspring. However, preclinical studies to date have not used voluntary self-administration of alcohol to examine alcohol related behaviors in offspring. Here, we tested the hypothesis that paternal alcohol self-administration followed by punishment-imposed abstinence alters alcohol consumption and seeking in male offspring. Male inbred alcohol preferring iP rats were trained to self-administer alcohol in one context followed by punishment-imposed suppression of alcohol-seeking in a different context using contingent footshock. Following this, all rats were bred with alcohol naive female iP rats. F1 offspring were then trained to self-administer alcohol in an identical operant paradigm as sires. Alcohol intake and self-administration behaviors of alcohol-sired offspring were compared to control-sired offspring whose fathers had not been exposed to the alcohol operant conditioning experience. We found that paternal alcohol self-administration reduced context induced relapse to alcohol-seeking in male offspring. These findings indicate that voluntary paternal alcohol experience, operant conditioning, and punishment can result in intergenerational changes in offspring behavior, and that this effect may protect against the vulnerability to relapse after alcohol use. We also noted reduced alcohol responding in the punishment-associated context in alcohol-sired offspring, suggesting altered perception of punishment sensitivity or the anxiogenic response to footshock. Collectively, these findings provide evidence that paternal alcohol abuse can impact alcohol-related behaviors in male offspring. PMID- 29468071 TI - Dietary tetrahydrocurcumin reduces renal fibrosis and cardiac hypertrophy in 5/6 nephrectomized rats. AB - Tetrahydrocurcumin (THC) is the principal metabolite of curcumin and has antioxidant properties. In the present investigation, the effect of THC on renal and cardiovascular outcomes was studied in rats with chronic kidney disease (CKD). CKD rats were randomized following 5/6 nephrectomy to a special diet for 9 weeks which contained 1% THC (CKD+THC group). Low-dose polyenylphosphatidylcholine was used as a lipid carrier to increase bioavailability. Endpoints included tail blood pressure, normalized heart weight, plasma and urine biochemical data, and kidney tissue analyses. CKD animals demonstrated increased proteinuria, decreased creatinine clearance, hypertension, and cardiac hypertrophy. The antioxidant proteins CuZn SOD and glutathione peroxidase were decreased in the remnant kidney, while apoptosis (caspase-3) and fibrosis (alpha-SM actin) were increased. Renal fibrosis was confirmed histologically on trichrome staining. These pathologic changes were ameliorated in the CKD+THC group with significant decrease in proteinuria, hypertension, and kidney fibrosis. THC therapy restored levels of CuZn SOD and glutathione peroxidase. Consistent with prior reports, dietary THC did not improve nuclear Nrf2 levels. In summary, dietary THC therapy improved expression of antioxidant proteins in the remnant kidney, decreased renal fibrosis and proteinuria, and ameliorated hypertension in 5/6 nephrectomized rats. PMID- 29468072 TI - Investigation of cardiopulmonary exercise testing using a dynamic leg press and comparison with a cycle ergometer. AB - Background: Leg-press machines are widely employed for musculoskeletal conditioning of the lower-limbs and they provide cardiovascular benefits for resistance training in cardiac patients. The aim of this study was to assess the feasibility of a dynamic leg press (DLP) for incremental cardiopulmonary exercise testing (CPET) and to compare the results with those obtained using a cycle ergometer (CE). Methods: Twelve healthy participants aged 27+/-4 years (mean +/- standard deviation) performed incremental cardiopulmonary exercise tests on a DLP and on a CE. To facilitate CPET, the DLP was augmented with force and angle sensors, a work rate estimation algorithm, and a visual feedback system. Gas exchange variables and heart rate were recorded breath-by-breath using a cardiopulmonary monitoring system. Results: Peak oxygen uptake and peak heart rate were significantly lower for the DLP than for the CE: peak oxygen uptake was 3.2+/-0.5 vs. 4.1+/-0.5 L/min (DLP vs. CE, p=6.7*10-6); peak heart rate was 174+/ 14 vs. 182+/-13 bpm (DLP vs. CE, p=0.0016). Likewise, the sub-maximal cardiopulmonary parameters, viz. the first and second ventilatory thresholds, and ramp duration were significantly lower for the DLP. Conclusions: The dynamic leg press was found to be feasible for CPET: the approach was technically implementable and all peak and sub-maximal cardiopulmonary parameters were able to be identified. The lower outcome values observed with the DLP can be attributed to a peripheral factor, namely the earlier onset of muscular fatigue. PMID- 29468073 TI - Survival prediction in mesothelioma using a scalable Lasso regression model: instructions for use and initial performance using clinical predictors. AB - Introduction: Accurate prognostication is difficult in malignant pleural mesothelioma (MPM). We developed a set of robust computational models to quantify the prognostic value of routinely available clinical data, which form the basis of published MPM prognostic models. Methods: Data regarding 269 patients with MPM were allocated to balanced training (n=169) and validation sets (n=100). Prognostic signatures (minimal length best performing multivariate trained models) were generated by least absolute shrinkage and selection operator regression for overall survival (OS), OS <6 months and OS <12 months. OS prediction was quantified using Somers DXY statistic, which varies from 0 to 1, with increasing concordance between observed and predicted outcomes. 6-month survival and 12-month survival were described by area under the curve (AUC) scores. Results: Median OS was 270 (IQR 140-450) days. The primary OS model assigned high weights to four predictors: age, performance status, white cell count and serum albumin, and after cross-validation performed significantly better than would be expected by chance (mean DXY0.332 (+/-0.019)). However, validation set DXY was only 0.221 (0.0935-0.346), equating to a 22% improvement in survival prediction than would be expected by chance. The 6-month and 12-month OS signatures included the same four predictors, in addition to epithelioid histology plus platelets and epithelioid histology plus C-reactive protein (mean AUC 0.758 (+/-0.022) and 0.737 (+/-0.012), respectively). The <6-month OS model demonstrated 74% sensitivity and 68% specificity. The <12-month OS model demonstrated 63% sensitivity and 79% specificity. Model content and performance were generally comparable with previous studies. Conclusions: The prognostic value of the basic clinical information contained in these, and previously published models, is fundamentally of limited value in accurately predicting MPM prognosis. The methods described are suitable for expansion using emerging predictors, including tumour genomics and volumetric staging. PMID- 29468074 TI - Development of a patient-centred, evidence-based and consensus-based discharge care bundle for patients with acute exacerbation of chronic obstructive pulmonary disease. AB - Introduction: Hospital and emergency department discharge for patients with chronic obstructive pulmonary disease (COPD) is often poorly organised. We developed a patient-centred, evidence-based and consensus-based discharge care bundle for patients with acute exacerbations of COPD. Methods: A purposeful sample of clinicians and patients were invited to participate in a two-round Delphi study (July-November 2015). In round 1, participants rated on a seven point Likert scale (1=not at all important; 7=extremely important) the importance of 29 unique COPD care actions. Round 2 comprised items selected from round 1 based on consensus (>80% endorsement for Likert values 5-7). A list of 18 care items from round 2 was discussed in a face-to-face nominal group meeting. Results: Seven care items were included in the COPD discharge bundle based on clinician and patient input: (1) ensure adequate inhaler technique is demonstrated; (2) send discharge summary to family physician and arrange follow up; (3) optimise and reconcile prescription of respiratory medications; (4) provide a written discharge management plan and assess patient's and caregiver's comprehension of discharge instructions; (5) refer to pulmonary rehabilitation; (6) screen for frailty and comorbidities; and (7) assess smoking status, provide counselling and refer to smoking cessation programme. Conclusion: We present a seven-item, patient-centred, evidence-based and consensus-based discharge bundle for patients with acute exacerbations of COPD. Alignment with clinical practice guidelines and feasibility of local adaptations of the bundle should be explored to facilitate wide applicability and evaluation of the effectiveness of the COPD discharge bundle. PMID- 29468075 TI - Television exposure and overweight/obesity among women in Ghana. AB - Background: Although the public health importance of the association between television (TV) viewing and obesity and/or related outcomes have been demonstrated in both cross-sectional and prospective studies elsewhere, similar studies are lacking within the African region. With the view to fill this gap in the literature, the current study explored the association between TV exposure and overweight/obesity among Ghanaian women. Methods: Based on a sample of 4158 women, descriptive statistics and binary logistic regression were applied to data on TV ownership, TV viewing frequency, and body mass index (BMI) measures from the 2014 Ghana Demographic and Health Survey (GDHS) to explore the association between TV exposure and overweight/obesity among Ghanaian women. Results: Despite controlling for other factors (age educational level, marital status, wealth quintile, occupation, type of locality, and parity), the results show that women with TV in their households, and with high TV exposure were significantly (P < 0.05) more likely (OR = 1.39, 95% CI = 1.002, 1.923) to be overweight/obese compared to those with no TV in their households, and no TV exposure. Conclusion: The study demonstrates that increased TV exposure is significantly associated with overweight/obesity among women in Ghana even after adjusting for other factors. Interventions aimed at tackling obesity in Ghana should focus on encouraging the uptake of more physically demanding pastime activities in place of TV "sit time". PMID- 29468076 TI - Capromorelin: a ghrelin receptor agonist and novel therapy for stimulation of appetite in dogs. AB - Ghrelin is a hormone, secreted from cells in the stomach, which is important in the regulation of appetite and food intake in mammals. It exerts its action by binding to a specific G-protein-coupled receptor, the growth hormone secretagogue receptor 1a (GHS-R1a) which is found in areas of the brain associated with the regulation of food intake. Ghrelin causes a release of growth hormone (GH) through binding to GHS-R1a in the hypothalamus and pituitary gland. A class of compounds known as growth hormone secretagogues, or ghrelin receptor agonists, were developed for therapeutic use in humans for the stimulation of GH in the frail elderly, and have subsequently been studied for their effects on increasing appetite and food intake, increasing body weight, building lean muscle mass, and treating cachexia. Subsequent research has shown that ghrelin has anti inflammatory and immunomodulatory effects. This article reviews the basic physiology of ghrelin and the ghrelin receptor agonists, including the available evidence of these effects in vitro and in vivo in rodent models, humans, dogs and cats. One of these compounds, capromorelin, has been FDA-approved for the stimulation of appetite in dogs (ENTYCE (r)). The data available on the safety and effectiveness of capromorelin is reviewed, along with a discussion of the potential clinical applications for ghrelin receptor agonists in both human and veterinary medicine. PMID- 29468077 TI - Molecular prevalence and phylogenetic analysis of Theileria annulata and Trypanosoma evansi in cattle in Northern Tunisia. AB - The present study aimed to estimate the molecular prevalence of Theileria annulata and Trypanosoma evansi infection in cattle in Northern Tunisia. A total number of 96 cattle from five farms were evaluated. T. annulata and T. evansi prevalences were 61% [56/66] and 10% [7/13], respectively, at a confidence interval (CI) of 95%, while co-infection was present in 6% [4/8] of the tested animals at a CI of 95%. There was a significant correlation between age and the prevalence of T. annulata infection, whereas, there was no significant association shown with the age of cattle and T. evansi infection. Sequence and phylogenetic analyses showed that the T. annulata Tams1 gene and T. evansi ITS1 rDNA gene were highly conserved with 97.1-100% and 98.3-100% sequence identity, respectively. PMID- 29468078 TI - Serovars and antimicrobial resistance of non-typhoidal Salmonella isolated from non-diarrhoeic dogs in Grenada, West Indies. AB - Non-typhoidal salmonellosis remains an important public health problem worldwide. Dogs may harbour Salmonella in their intestines and can easily shed Salmonella in the environment with the possibility of transmission to humans. Thus, monitoring is essential to understand the role of dogs in zoonotic transmission. The objectives of this study were to determine the shedding of Salmonella by owned, apparently healthy dogs in Grenada, West Indies, to identify the serovars, and to examine their antimicrobial susceptibility profiles. Faecal samples collected during August to October, 2016 from 144 non-diarrhoeic owned dogs were examined by enrichment and selective culture for the presence of Salmonella spp. Eight (5.6%) of the tested animals were culture positive, yielding 35 Salmonella isolates that belonged to six serovars of Salmonella enterica subspecies enterica. These were serovars Arechavaleta from two dogs, Arechavaleta and Montevideo from one dog, and Javiana, Rubislaw, Braenderup and Kiambu from one dog each. All these serovars have been reported as causes of human salmonellosis globally. Antimicrobial susceptibility tests on 35 isolates showed absence of resistance to the currently used drugs for cases of human salmonellosis, including ciprofloxacin and cefotaxime. One isolate (2.9%) was resistant to neomycin, two isolates (5.7%) showed intermediate susceptibility to neomycin, and another (2.9%) had intermediate susceptibility to tetracycline. This is the first report of isolation and antimicrobial susceptibilities of non-typhoidal Salmonella serovars from dogs in Grenada. This study shows that dogs in Grenada may be involved in the epidemiology of salmonellosis. PMID- 29468079 TI - Effect of vaccine storage temperatures and dose rate on antibody responses to foot and mouth disease vaccination in Cambodia. AB - A field study investigated the effects of foot and mouth disease vaccine storage temperature for 7 days (frozen, refrigerated or held at ambient temperature) and dose (half or full dose) on the serological response to vaccination. It utilised a complete factorial design replicated on 18 smallholder cattle farms in three villages in Pursat province, Cambodia. Antibody responses from the 108 cattle involved were assessed by serological examination of blood samples collected at primary vaccination (day 0), at booster vaccination (day 30) and finally at 60 days post primary vaccination. Vaccination responses to the inactivated vaccine were assessed by testing for antibodies directed against FMD structural proteins in a liquid-phase blocking ELISA (LPBE test) and differentiated from responses to natural infection by examining antibody titres against non-structural viral proteins (NSPE test). LPBE results indicated that the mean log10 LPBE antibody titres of all experimental cattle increased from below protective levels at day 0 to protective levels at 30 days post primary vaccination, and increased further at 60 days post primary vaccination. Storage at ambient temperature for 1 week had no effect on antibody response to vaccination. However, freezing the vaccine for a week or use of a half dose resulted in significant reduction in titres at day 60 (P = 0.04 and P = 0.02, respectively). The results of this study reinforce the need to store FMD vaccines within the range recommended by the manufacturers and to adhere to the specified dosage instructions. PMID- 29468080 TI - An outbreak of classical swine fever in pigs in Bangladesh, 2015. AB - In a group of 22 healthy pigs aged between 4 and 6 months, 2 pigs became ill with high fever, complete anorexia, cough and abnormal swaying movements on 22 June 2015. One of them died on June 24 and the second died on July 3. Shortly after, the remaining pigs also fell ill and died from the same illness by 10 August 2015. We investigated the aetiology, epidemiological and clinical features of the outbreak. We recorded the clinical signs and symptoms for each pig with the date of onset of illness. Veterinarians conducted post-mortem examinations on the 12 dead pigs, they collected tissue samples from the dead pigs and placed them in a tube containing 1 mL of nucleic acid extraction buffer (lysis buffer). We tested all the tissue samples by real-time reverse transcription polymerase chain reaction (rRT-PCR) to detect classical swine fever virus (CSFV) because the animals' symptoms matched those of this disease. We also conducted a phylogentic analysis of the nucleotide sequence of the E2 gene segment of CSFV detected in a lung tissue sample. The attack rate (22/22) and the case fatality were 100%. The predominant symptoms of the disease included high fever, cough, diarrhoea and swaying movements of the hind legs prior to death. Of the 12 pigs tissue samples tested, all had evidence of the presence of CSFV RNA by rRT-PCR. The phylogenetic analysis indicated that the virus belongs to genotype 2.2, which is closely related to CSFV genotype 2.2 reported in India. Our investigation suggests that CSF is circulating in pigs, posing a risk for communities in Bangladesh that rely on pigs for economic income and dietary protein. Future research could focus on estimating the disease and economic burden of CSFV in pig rearing areas to determine if interventions might be warranted or cost-effective. PMID- 29468081 TI - Progressive cutaneous viral pigmented plaques in three Hungarian Vizslas and the response of lesions to topical tigilanol tiglate gel. AB - Cutaneous pigmented viral plaques is a disorder of epidermal growth caused by canine papillomavirus type 4 (CPV-4). There is currently no standard of care for managing this condition and it has not been reported in the Hungarian Vizsla. This case series documents the clinical features of canine pigmented viral plaques in Hungarian Vizsla dogs and the treatment of a severe case using a novel topical agent tigilanol tiglate (EBC-46). A 4-year-old spayed Hungarian Vizsla in Australia was presented for multiple cutaneous pigmented plaques extending from the ventral cervical region. Lesions were neither painful nor pruritic. The number and size of these sessile plaques increased over time, with the largest lesions eventually taking on an exophytic (wart-like) appearance. These lesions did not affect the dog's wellbeing. Two much less severe cases in a 5-year-old Vizsla from the UK and a 7-year-old Vizsla from New Zealand were also diagnosed. Histology was consistent with papillomavirus-induced pigmented plaques and CPV-4 DNA sequences were amplified from paraffin-embedded formalin-fixed tissue using the polymerase chain reaction from the most severely affected patient. Topical imiquimod was ineffective although used for only a short time. Two topical applications of novel anti-neoplastic diterpene ester tigilanol tiglate as a gel, 9 days apart, greatly reduced the size and number of lesions in a limited portion of skin treated, over the lateral hock. While CPV-4 has been previously reported to cause pigmented plaques, most commonly on pug dogs, but sporadically on other breeds, this is the first report of this virus causing plaques in Hungarian Vizslas. The cases illustrate some of the difficulties in diagnosing papillomavirus-induced disease in dogs, especially in its early stages. Topical tigilanol tiglate is a potentially useful topical therapy for this viral-induced disorder of cell growth and represents a treatment deserving of further investigation. PMID- 29468082 TI - Concurrent thoracic mesothelioma and thyroid C-cell adenoma with amyloid deposition in an aged horse. AB - A 21-year-old American Saddlebred mare died with a history of weight loss and breathing difficulties of 1 month duration. Post-mortem examination revealed a copious pleural effusion with multifocal to coalescing numerous white to grey nodular masses on the serosal surface of the pericardium, lungs and thoracic cavity. In addition, the left thyroid gland was markedly enlarged. A thoracic mesothelioma and C-cell adenoma with amyloid deposits of the left thyroid gland were diagnosed by histopathology and confirmed by immunohistochemistry employing antibodies against cytokeratin (CK), vimentin and calcitonin. Amyloid deposits in the thyroid tumour were confirmed by Congo red staining with apple-green birefringence under polarized light. Mesothelioma remains an uncommon neoplasm encountered in aged horses. Discussion includes the diagnostic challenge of differentiating carcinomatosis from mesothelioma by histology and differentiating reactive and neoplastic mesothelial cells by cytology. PMID- 29468083 TI - Research note: a resting-state, cerebello-amygdaloid intrinsically connected network. AB - Background: Previous ROI-based functional connectivity studies found functional coherence between cerebellum and cerebral amygdale, at rest. Moreover, some neurospychiatric symptoms were accompanied by abnormal activations of these two brain areas. Therefore, the aim of the study was to identify a putative, resting state intrinsically connected cerebello-amygdaloid network. Methods: ICA-based analysis was performed on brain resting-state functional images of 15 volunteers. Results: The first ICA spatial component corresponded to a circuit including: dentate nuclei, lobules VI and VIII, the basolateral amygdala, the substantia nigra, the posterior insula, claustrum and the parietal opercule. Conclusion: A new intrinsically connected network linking cerebellum and amygdala is described, which could be in charge of sensorimotor, emotional and motivational integration of somesthesic stimuli before recruiting more specialized circuits such as ventral striatum or attentional and salience networks. PMID- 29468085 TI - Feasibility of a combined aerobic and cognitive training intervention on cognitive function in cancer survivors: a pilot investigation. AB - Background: Cancer-related cognitive impairment (CRCI) may negatively affect upwards of 75% of cancer patients. Exercise and cognitive training, independently, may increase functional capacity and aspects of cognitive function. Yet, combined training protocols have not been evaluated in cancer survivor populations. Therefore, the aim of this study was to explore the feasibility of a quasi-randomized, controlled, exploratory, repeated-measures aerobic and cognitive training intervention on cognitive function in participants undergoing treatment for cancer (N = 28). Methods: Pre- and post-physical and cognitive assessments were administered. A 36-session (approximately 12 weeks) computer-based cognitive (COG), aerobic (AER), cognitive and aerobic (AER + COG), and flexibility (CON) training intervention was completed. Dependent measures t tests and pre- to post percentages were then calculated to address within-group changes for each dependent variable. Results: Within-group measures revealed that the AER logical memory scores (pre- to post mean difference [2.3], 95.0% CI [0.9, 3.7], percentage change [32.7%]), delayed recall scores (pre- to post mean difference [2.1], 95.0% CI [0.3, 3.9], percentage change [27.2%]), block design scores (pre- to post mean difference [1.7], 95.0% CI [0.2, 3.2], percentage change [19.0%]), and letter-number sequencing scores (pre- to post mean difference [1.0], 95.0% CI [0.2, 1.8], percentage change [12.3%]) all increased. Aspects of verbal fluidity scores increased in the CON group. However, all cognitive scores (AER + COG and COG groups) failed to increase. Conclusions: Aerobic training for CRCI may positively impact cognitive function. Individually, these methods may appropriately address CRCI, but combined training of this nature may be too demanding for patients undergoing treatment for cancer. However, larger randomized trials are needed to substantiate this protocol in large-scale cancer rehabilitation centers. PMID- 29468084 TI - A development study and randomised feasibility trial of a tailored intervention to improve activity and reduce falls in older adults with mild cognitive impairment and mild dementia. AB - Background: People with dementia progressively lose abilities and are prone to falling. Exercise- and activity-based interventions hold the prospect of increasing abilities, reducing falls, and slowing decline in cognition. Current falls prevention approaches are poorly suited to people with dementia, however, and are of uncertain effectiveness. We used multiple sources, and a co-production approach, to develop a new intervention, which we will evaluate in a feasibility randomised controlled trial (RCT), with embedded adherence, process and economic analyses. Methods: We will recruit people with mild cognitive impairment or mild dementia from memory assessment clinics, and a family member or carer. We will randomise participants between a therapy programme with high intensity supervision over 12 months, a therapy programme with moderate intensity supervision over 3 months, and brief falls assessment and advice as a control intervention. The therapy programmes will be delivered at home by mental health specialist therapists and therapy assistants. We will measure activities of daily living, falls and a battery of intermediate and distal health status outcomes, including activity, balance, cognition, mood and quality of life. The main aim is to test recruitment and retention, intervention delivery, data collection and other trial processes in advance of a planned definitive RCT. We will also study motivation and adherence, and conduct a process evaluation to help understand why results occurred using mixed methods, including a qualitative interview study and scales measuring psychological, motivation and communication variables. We will undertake an economic study, including modelling of future impact and cost to end of-life, and a social return on investment analysis. Discussion: In this study, we aim to better understand the practicalities of both intervention and research delivery, and to generate substantial new knowledge on motivation, adherence and the approach to economic analysis. This will enable us to refine a novel intervention to promote activity and safety after a diagnosis of dementia, which will be evaluated in a definitive randomised controlled trial.

PMID- 29468086 TI - DNA metabarcoding of spiders, insects, and springtails for exploring potential linkage between above- and below-ground food webs. AB - Background: Understanding feedback between above- and below-ground processes of biological communities is a key to the effective management of natural and agricultural ecosystems. However, as above- and below-ground food webs are often studied separately, our knowledge of material flow and community dynamics in terrestrial ecosystems remains limited. Results: We developed a high-throughput sequencing method for examining how spiders link above- and below-ground food webs as generalist predators. To overcome problems related to DNA-barcoding-based analyses of arthropod-arthropod interactions, we designed spider-specific blocking primers and Hexapoda-specific primers for the selective PCR amplification of Hexapoda prey sequences from spider samples. By applying the new DNA metabarcoding framework to spider samples collected in a temperate secondary forest in Japan, we explored the structure of a food web involving 15 spider species and various taxonomic groups of Hexapoda prey. These results support the hypothesis that multiple spider species in a community can prey on both above- and below-ground prey species, potentially coupling above- and below-ground food web dynamics. Conclusions: The PCR primers and metabarcoding pipeline described in this study are expected to accelerate nuclear marker-based analyses of food webs, illuminating poorly understood trophic interactions in ecosystems. PMID- 29468087 TI - Development of hypobranchial muscles with special reference to the evolution of the vertebrate neck. AB - Background: The extant vertebrates include cyclostomes (lamprey and hagfish) and crown gnathostomes (jawed vertebrates), but there are various anatomical disparities between these two groups. Conspicuous in the gnathostomes is the neck, which occupies the interfacial domain between the head and trunk, including the occipital part of the cranium, the shoulder girdle, and the cucullaris and hypobranchial muscles (HBMs). Of these, HBMs originate from occipital somites to form the ventral pharyngeal and neck musculature in gnathostomes. Cyclostomes also have HBMs on the ventral pharynx, but lack the other neck elements, including the occipital region, the pectoral girdle, and cucullaris muscles. These anatomical differences raise questions about the evolution of the neck in vertebrates. Results: In this study, we observed developing HBMs as a basis for comparison between the two groups and show that the arrangement of the head-trunk interface in gnathostomes is distinct from that of lampreys. Our comparative analyses reveal that, although HBM precursors initially pass through the lateral side of the pericardium in both groups, the relative positions of the pericardium withrespect to the pharyngeal arches differ between the two, resulting in diverse trajectories of HBMs in gnathostomes and lampreys. Conclusions: We suggest that a heterotopic rearrangement of early embryonic components, including the pericardium and pharyngeal arches, may have played a fundamental role in establishing the gnathostome HBMs, which would also have served as the basis for neck formation in the jawed vertebrate lineage. PMID- 29468088 TI - Neck circumference is independently associated with relative systemic hypertension in young adults with sickle cell anaemia. AB - Background: A seemingly interesting observation in patients with sickle cell anaemia (SCA) is that they usually have lower systemic blood pressures (BP) and insulin resistance than persons in the general population in spite of chronic inflammation and vasculopathy. However, relative systemic hypertension (rHTN) has been linked to pulmonary hypertension, increased blood viscosity and renal insufficiency, which could indicate a risk of developing cardiometabolic disorder (CMD) in SCA.We therefore hypothesized that neck circumference (NC) and CMD marker; triglyceride glucose (TyG) index would independently predict rHTN in young adults with SCA in steady state. Methods: We compared the anthropometrical, hematological, hemorheological and CMD markers between SCA patients with normal BP < 120/70 mmHg; nHTN, n = 65) and those with rHTN (BP >= 120/70 mmHg, n = 32). Results: Our results showed that SCA with rHTN had significantly higher body weight, waist circumference, NC, plasma viscosity, systolic and diastolic BP. Results also indicated that NC (OR: 2.98; 95% CI 1.46 to 6.10, p < 0.01) was a predictor of rHTN in SCA independent of gender, age, weight, waist circumference, BMI, blood viscosity, triglyceride or TyG. A receiver operating characteristic curve analysis also showed that NC was the most efficient predictor of rHTN than other CMD markers. Conclusion: The present study demonstrates that increased NC is a salient risk factors that is independently associated with rHTN in SCA. The finding therefore underscores the utility of NC in early detection and stratification of systemic hypertension, particularly in individuals with SCA. PMID- 29468089 TI - The necessary conditions of engagement for the therapeutic relationship in physiotherapy: an interpretive description study. AB - Background: The therapeutic relationship between patient and physiotherapist is a central component of patient-centred care and has been positively associated with better physiotherapy clinical outcomes. Despite its influence, we do not know what conditions enable a physiotherapist and patient to establish and maintain a therapeutic relationship. This knowledge has implications for how clinicians approach their interactions with patients and for the development of an assessment tool that accurately reflects the nature of the therapeutic relationship. Therefore, this study's aim was to identify and provide in-depth descriptions of the necessary conditions of engagement of the therapeutic relationship between physiotherapists and patients. Methods: Interpretive description was the qualitative methodological orientation used to identify and describe the conditions that reflect and are practically relevant to clinical practice. Eleven physiotherapists with a minimum 5 years of clinical experience and seven adult patients with musculoskeletal disorders were purposively sampled from private practice clinics in Edmonton, Canada. The in-person, semi-structured interviews were completed in a location of the participant's choice and were audio recorded and transcribed. Qualitative content analysis was used to analyze the textual data and constant comparison techniques were integrated to refine the categories and sub-categories. Rigour strategies used throughout the study were peer debrief, interview notes, reflexive journaling, memoing, member reflections, audit trail, and external audit. Results: Four conditions were identified as necessary for establishing a therapeutic relationship: present, receptive, genuine, and committed. These conditions represent the intentions and attitudes of physiotherapists and patients engaging in the clinical interaction. Although distinct, the conditions appear related as being present and receptive create a foundation for being genuine and committed. Conclusions: These conditions of engagement are needed for physiotherapist and patient to "be" in a therapeutic relationship. Although communication skills are important for advancing therapists' relational abilities, awareness and integration of intentions and attitudes are essential for shaping behaviors that develop the therapeutic relationship. These findings also suggest there are characteristics of the therapeutic relationship specific to physiotherapy. Therefore, theories from other contexts (e.g., psychotherapy) should be used judiciously to guide physiotherapy practice and research. PMID- 29468090 TI - The Role of BMI in Hip Fracture Surgery. AB - Introduction: Obesity is an oft-cited cause of surgical morbidity and many institutions require extensive supplementary screening for obese patients prior to surgical intervention. However, in the elderly patients, obesity has been described as a protective factor. This article set out to examine the effect of body mass index (BMI) on outcomes and morbidity after hip fracture surgery. Methods: The National Surgical Quality Improvement Program database was queried for all patients undergoing 1 of 4 surgical procedures to manage hip fracture between 2008 and 2012. Patient demographics, BMI, and known factors that lead to poor surgical outcomes were included as putative predictors for complications that included infectious, cardiac, pulmonary, renal, and neurovascular events. Using chi2 tests, 30-day postoperative complication rates were compared between 4 patient groups stratified by BMI as low weight (BMI < 20), normal (BMI = 20-30), obese (BMI = 30-40), and morbidly obese (BMI > 40). Results: A total of 15 108 patients underwent surgery for hip fracture over the examined 5-year period. Of these, 18% were low weight (BMI < 20), 67% were normal weight (BMI = 20-30), 13% were obese (BMI = 30-40), and 2% were morbidly obese (BMI > 40). The low-weight and morbidly obese patients had both the highest mortality rates and the lowest superficial infection rates. There was a significant increase in blood transfusion rates that decreased linearly with increasing BMI. Deep surgical site infection and renal failure increased linearly with increasing BMI, however, these outcomes were confounded by comorbidities. Conclusion: This study demonstrates that patients at either extreme of the BMI spectrum, rather than solely the obese, are at greatest risk of major adverse events following hip fracture surgery. This runs contrary to the notion that obese hip fracture patients automatically require additional preoperative screening and perioperative services, as currently implemented in many institutions. PMID- 29468092 TI - Effectiveness of Culturally Appropriate Adaptations to Juvenile Justice Services. AB - Despite efforts to increase cultural competence of services within juvenile justice systems, disproportional minority contact (DMC) persists throughout Canada and the United States. Commonly cited approaches to decreasing DMC include large-scale systemic changes as well as enhancement of the cultural relevance and responsiveness of services delivered. Cultural adaptations to service delivery focus on prevention, decision-making, and treatment services to reduce initial contact, minimize unnecessary restraint, and reduce recidivism. Though locating rigorous testing of these approaches compared to standard interventions is difficult, this paper identifies and reports on such research. The Cochrane guidelines for systematic literature reviews and meta-analyses served as a foundation for study methodology. Databases such as Legal Periodicals and Books were searched through June 2015. Three studies were sufficiently rigorous to identify the effect of the cultural adaptations, and three studies that are making potentially important contributions to the field were also reviewed. PMID- 29468093 TI - Integration of Health Coaching Concepts and Skills into Clinical Practice Among VHA Providers: A Qualitative Study. AB - Background: Although studies of health coaching for behavior change in chronic disease prevention and management are increasing, to date no studies have reported on what concepts and skills providers integrate into their clinical practice following participation in health coaching courses. The purpose of this qualitative study was to assess Veterans Health Administration (VHA) providers' perceptions of the individual-level and system-level changes they observed after participating with colleagues in a 6-day Whole Health Coaching course held in 8 VHA medical centers nationwide. Methods: Data for this study were from the follow up survey conducted with participants 2 to 3 months after completing the training. A total of 142 responses about individual-level changes and 99 responses about system-level changes were analyzed using content analysis. Results: Eight primary themes emerged regarding individual changes, including increased emphasis on Veterans' values, increased use of listening and other specific health coaching skills in their clinical role, and adding health coaching to their clinical practice.Four primary themes emerged regarding system level changes, including leadership support, increased staff awareness/support/learning and sharing, increased use of health coaching skills or tools within the facility, and organizational changes demonstrating a more engaged workforce, such as new work groups being formed or existing groups becoming more active. Conclusions: Findings suggest that VHA providers who participate in health coaching trainings do perceive positive changes within themselves and their organizations. Health coaching courses that emphasize patient-centered care and promote patient-provider partnerships likely have positive effects beyond the individual participants that can be used to promote desired organizational change. PMID- 29468091 TI - Surgical Technical Evidence Review for Elective Total Joint Replacement Conducted for the AHRQ Safety Program for Improving Surgical Care and Recovery. AB - Background: Use of enhanced recovery pathways (ERPs) can improve patient outcomes, yet national implementation of these pathways remains low. The Agency for Healthcare Research and Quality (AHRQ; funder), the American College of Surgeons, and the Johns Hopkins Medicine Armstrong Institute for Patent Safety and Quality have developed the Safety Program for Improving Surgical Care and Recovery-a national effort to catalyze implementation of practices to improve perioperative care and enhance recovery of surgical patients. This review synthesizes evidence that can be used to develop a protocol for elective total knee arthroplasty (TKA) and total hip arthroplasty (THA). Study Design: This review focuses on potential components of the protocol relevant to surgeons; anesthesia components are reported separately. Components were identified through review of existing pathways and from consultation with technical experts. For each, a structured review of MEDLINE identified systematic reviews, randomized trials, and observational studies that reported on these components in patients undergoing elective TKA/THA. This primary evidence review was combined with existing clinical guidelines in a narrative format. Results: Sixteen components were reviewed. Of the 10 preoperative components, most were focused on risk factor assessment including anemia, diabetes mellitus, tobacco use, obesity, nutrition, immune-modulating therapy, and opiates. Preoperative education, venous thromboembolism (VTE) prophylaxis, and bathing/Staphylococcus aureus decolonization were also included. The routine use of drains was the only intraoperative component evaluated. The 5 postoperative components included early mobilization, continuous passive motion, extended duration VTE prophylaxis, early oral alimentation, and discharge planning. Conclusion: This review synthesizes the evidence supporting potential surgical components of an ERP for elective TKA/THA. The AHRQ Safety Program for Improving Surgical Care and Recovery aims to guide hospitals and surgeons in identifying the best practices to implement in the surgical care of TKA and THA patients. PMID- 29468094 TI - CHOBS: Color Histogram of Block Statistics for Automatic Bleeding Detection in Wireless Capsule Endoscopy Video. AB - Wireless capsule endoscopy (WCE) is the most advanced technology to visualize whole gastrointestinal (GI) tract in a non-invasive way. But the major disadvantage here, it takes long reviewing time, which is very laborious as continuous manual intervention is necessary. In order to reduce the burden of the clinician, in this paper, an automatic bleeding detection method for WCE video is proposed based on the color histogram of block statistics, namely CHOBS. A single pixel in WCE image may be distorted due to the capsule motion in the GI tract. Instead of considering individual pixel values, a block surrounding to that individual pixel is chosen for extracting local statistical features. By combining local block features of three different color planes of RGB color space, an index value is defined. A color histogram, which is extracted from those index values, provides distinguishable color texture feature. A feature reduction technique utilizing color histogram pattern and principal component analysis is proposed, which can drastically reduce the feature dimension. For bleeding zone detection, blocks are classified using extracted local features that do not incorporate any computational burden for feature extraction. From extensive experimentation on several WCE videos and 2300 images, which are collected from a publicly available database, a very satisfactory bleeding frame and zone detection performance is achieved in comparison to that obtained by some of the existing methods. In the case of bleeding frame detection, the accuracy, sensitivity, and specificity obtained from proposed method are 97.85%, 99.47%, and 99.15%, respectively, and in the case of bleeding zone detection, 95.75% of precision is achieved. The proposed method offers not only low feature dimension but also highly satisfactory bleeding detection performance, which even can effectively detect bleeding frame and zone in a continuous WCE video data. PMID- 29468095 TI - Intraoral Dissection of the Mimetic Muscles: Application to Dentistry and Oral Surgery. AB - Mimetic muscles contract and pull the overlying skin toward the muscle's bony attachment. Numerous books and articles have shown the mimetic muscles via cadaveric dissection. However, for dentistry and oral surgery, the mimetic muscles have not been detailed from intraoral dissection. Recently, several papers have addressed various mimetic muscles in relation to intraoral dissection. However, to our knowledge, there has been no overview of these muscles beneath the oral mucosa. Here, we review the literature concerning the mimetic muscles as revealed during intraoral dissection, create novel illustrations, and discuss the relationship of these muscles with general dentistry and oral surgery. The mimetic muscles, which constitute the surface of the oral mucosa, the relationship of the labial and buccal frenulum and mimetic muscles, the relationship of the mucogingival junction and mimetic muscles, and other surgical procedures are discussed. A better understanding of the mimetic muscles from an intraoral perspective is important for those performing oral surgery and dentistry. PMID- 29468096 TI - Omental Infarction: The Great Impersonator. AB - A 58-year-old female presented to the emergency department with intermittent right upper quadrant pain and nausea. On examination, the patient was tender and Murphy's sign was elicited. A presumptive diagnosis of acute cholecystitis was made but an ultrasound of the abdomen revealed a thin-walled gallbladder without calculi. A computed tomography (CT) scan of the abdomen and pelvis demonstrated fat stranding involving the greater omentum and the right paracolic gutter. The patient was diagnosed with a focal omental infarction and underwent emergency laparoscopic surgery. Intraoperatively, the thickened and infarcted omental segment was dissected off the abdominal wall, liver, and mesocolon and removed through the umbilical port site using an Endo CatchTM (Covidien Ltd, Dublin, Republic of Ireland). This paper presents a rare case of omental infarction and illustrates how it can mimic the classic presentation of acute cholecystitis. The literature around the incidence, pathogenesis, and management of omental infarction is reviewed and presented to the reader. PMID- 29468097 TI - An Uncommon Case of Renal Metastasis from Cervical Cancer. AB - Metastases to the kidney are a rare entity. Among solid tumors, it is known that lung and colorectal cancers can metastasize to the kidney. Renal metastases from cervical cancer are exceptional; only 12 cases were previously reported. We report a case of a right renal metastasis from a cervical squamous cell carcinoma, occurring in the context of a metastatic relapse two years after completing primary treatment. PMID- 29468098 TI - Dengue Maculopathy with Foveolitis in a Postpartum Female. AB - Dengue fever is common in the tropics and its clinical manifestations and complications are well-known. However, dengue-related ocular complications are rare. Here we present a postpartum female who complained of bilateral central scotoma, at five days after the clinical diagnosis of dengue fever. The ocular examination was suggestive of dengue maculopathy and foveolitis. She was treated with a combination of intravenous methylprednisolone and immunoglobulin. The final visual recovery was good. PMID- 29468099 TI - Effect of Gamma Knife Radiosurgery and Programmed Cell Death 1 Receptor Antagonists on Metastatic Melanoma. AB - Learning objectives To evaluate radiation-induced changes in patients with brain metastasis secondary to malignant melanoma who received treatment with Gamma Knife radiosurgery (GKRS) and programmed cell death 1 (PD-1) receptor antagonists. Introduction Stereotactic radiosurgery and chemotherapeutics are used together for treatment of metastatic melanoma and have been linked to delayed radiation-induced vasculitic leukoencephalopathy (DRIVL). There have been reports of more intense interactions with new immunotherapeutics targeting PD-1 receptors, but their interactions have not been well described and may result in an accelerated response to GKRS. Here we present data on subjects treated with this combination from a single institution. Methods Records from patients who underwent treatment for metastatic melanoma to the brain with GKRS from 2011 to 2016 were reviewed. Demographics, date of brain metastasis diagnosis, cause of death when applicable, immunotherapeutics, and imaging findings were recorded. The timing of radiation therapy and medications were also documented. Results A total of 79 subjects were treated with GKRS, and 66 underwent treatment with both GKRS and immunotherapy. Regarding the 30 patients treated with anti-PD-1 immunotherapy, 21 patients received pembrolizumab, seven patients received nivolumab, and two patients received pembrolizumab and nivolumab. Serial imaging was available for interpretation in 25 patients, with 13 subjects who received GKRS and anti-PD-1 immunotherapy less than six weeks of each other. While four subjects had indeterminate/mixed findings on subsequent magnetic resonance imaging (MRI), nine subjects were noted to have progression. Two of these patients showed progression but subsequent imaging revealed a decrease in progression or improvement on MRI to previously targeted lesions by GKRS. None of the 13 subjects had surgery following their combined therapies. Conclusions This data suggests that there is need for further investigation of the role for concurrent treatment with PD-1 inhibitors and GKRS to enhance the treatment of metastatic melanoma. We present data on 13 patients who appear to have some radiologic benefit to this treatment combination, two of whom had radiographic pseudoprogression. PMID- 29468100 TI - Bursal Synovial Chondromatosis Secondary to Underlying Osteochondroma in a Child. AB - Osteochondroma and synovial chondromatosis are frequently reported benign bony and cartilaginous lesions. Osteochondroma is distinguished by a cartilage-capped bony exostosis on the exterior surface of the bone, whereas synovial chondromatosis is secondary to metaplasia and is characterized by multiple cartilaginous loose bodies within the synovium. We present an atypical case of synovial chondromatosis developing in a bursa sec-ondary to an underlying osteochondroma of the proximal medial tibia in a child. It is extremely rare to see both these conditions occurring in one location simultaneously. Moreover, this association is an unusual occurrence in the pediatric age group. The patient underwent surgical excision of the lesions and the final diagnosis was confirmed on histology. Simulation to malignant degeneration is often observed and vigilant assessment of both lesions is essential to exclude the possibility of sarcomatous transformation in those who present with these conditions since clinical, radiological, and histopathological features may overlap. However, a proper preoperative distinction may prevent an unnecessary aggressive therapeutic approach, which stood true for our case. PMID- 29468101 TI - Idiopathic Sudden Sensorineural Hearing Loss: Average Time Elapsed Before Presentation to the Otolaryngologist and Effectiveness of Oral and/or Intratympanic Steroids in Late Presentations. AB - Objectives To determine how long after symptom onset that the average patient with an idiopathic sudden sensorineural hearing loss (ISSNHL) presents to the otolaryngology clinic. In late presentations, to determine the time to presentation cutoff after which intervention may not be effective. To evaluate the effectiveness of oral steroids versus a combination of oral and intratympanic steroid therapy in late presentations of ISSNHL. Methods and procedures Sixty four patients met inclusion criteria after chart review of 2,037 patients seen at Metro Health Hospital from 2006 to 2016 for sensorineural hearing loss. All sixty four patients were used to calculate the average time to presentation, but only 40 were included to evaluate treatment efficacy because 24 were lost to follow-up or declined treatment. Audiograms were analyzed for baseline status and response to treatment. Therapy was either oral steroids or intratympanic (IT) steroids. Thirty-nine of the 40 treated patients received oral steroid therapy. Eighteen of these 39 patients received both oral and IT steroids. One patient received IT steroids only. Results For all 64 patients in the study, the average time to presentation was 55 days, ranging from one day to 240 days. Data for 32 of the 40 treated patients were analyzed. These patients were further divided into smaller groups: Group 1 (N = 11) - treatment within seven days of symptom onset, Group 2 (N = 17) - time to treatment greater than seven days but less than 90 days of symptom onset, and Group 3 (N = 4) - greater than 90 days of symptom onset. In Group 2, there was a significant improvement in pure tone average (P-value: 0.005). Forty-seven percent of patients in this group had objective treatment response utilizing Wilson's criteria. Two patients had a complete recovery and six had a partial recovery. Hearing gains ranged from 10 dB (decibels) to 23 dB. Sixty-three percent of patients with objective improvement also had subjective improvement. In Group 3, none of the patients met Wilson's criteria for recovery. There was no statistically significant difference in response between patients treated with oral steroids only versus a combination of oral and IT steroids. Conclusion Patients with ISSNHL present to an otolaryngologist on average 55 days after symptom onset. There is statistically and clinically significant response to treatment in late presenters. Improvement can be seen up to three months from symptom onset. Oral steroid therapy is effective. IT steroid therapy may have an added benefit. PMID- 29468102 TI - Role of Stereotactic Radiosurgery in the Management of Multiple Metastases in the Region of the Motor Cortex: Long-term Survival in Three Cases. AB - The management of patients with multiple brain metastases, in contrast to those with solitary metastases, continues to evolve. Recent evidence suggests that aggressive microsurgical and radiosurgical management of patients with multiple brain metastases may lead to improved survival and quality of life. The three cases discussed in this report are examples of patients with multiple brain metastases who had excellent outcomes following treatment with microsurgical and radiosurgical approaches. A common feature of each patient is the presence of multiple metastases in the region of the motor cortex. The rationale for this selection is to demonstrate that aggressive management can have a favorable outcome despite the presence of multiple metastases in eloquent regions of the brain. PMID- 29468103 TI - Atypical Location of Intracerebral Hemorrhage in Moyamoya Disease. AB - Moyamoya disease is a chronic, progressive bilateral occlusion or stenosis of terminal internal carotid arteries as well as the proximal anterior and middle cerebral arteries. Hemorrhage of the splenium of the corpus callosum rarely occurs with moyamoya disease. In this article, we report a case of a 53-year-old woman diagnosed with moyamoya disease by cerebral angiography. She presented to the emergency department complaining of unsteadiness and a tendency to fall forward for one week. The patient was investigated with head computed tomography (CT) scan upon presentation revealing atypical location of hemorrhage in the corpus callosum, mainly in the splenium. PMID- 29468104 TI - Cerebellar Stroke Occupational Therapy and Physical Therapy Management from Intensive Care Unit to Outpatient: A Case Report. AB - Cerebellar stroke increases the risk of extensive physical disability and long term institutionalization. The purpose of this case report is to describe the 14 month longitudinal rehabilitation management and outcomes from the intensive care unit, inpatient rehabilitation unit and outpatient care of a patient after cerebellar stroke. A goal of this case report is to provide rehabilitation clinicians with a long-term perspective and understanding of the course of recovery for a patient after cerebellar cerebrovascular accident or related injury. A 51-year-old healthy athletic female experienced acute bilateral cerebellar infarcts with subsequent craniotomy to remove infarcted areas. The patient had postoperative hemorrhages and hydrocephalus and was deemed to have a poor prognosis. Multimodal sensory stimulation and early mobility was performed until conventional neuromuscular reeducation interventions could be tolerated. Primary deficits included decreased proximal strength, whole body ataxia, vertical diplopia, dysphagia, difficulty communicating, and emotional lability. Fourteen months after the initial infarcts, the patient was able to reside in her own home with her husband, ambulate, and stand with assistance and perform most activities of daily living with standby or set-up assistance. This patient made significant progress toward safety and mobility and was able to return home despite the early discussion about a poor prognosis and a palliative care consultation. The complex, intensive course of rehabilitation elicited slow, steady, consistent gains. The patient's motivation and family involvement likely facilitated optimum outcomes. PMID- 29468105 TI - Smaller Radius Width in Women With Distal Radius Fractures Compared to Women Without Fractures. AB - Introduction Bone mineral density (BMD) measured using dual-energy x-ray absorptiometry (DXA) is typically used to assess fracture risk. However, other factors such as bone size and the forward momentum of a fall (a function of body size) can also potentially influence fracture risk, but are understudied. This report describes the characteristics of a cohort of Caucasian pre- and postmenopausal women with distal radius fractures (DRF) after falling onto an outstretched hand. Methods The fracture cohort comprised entries in an institutional review board-approved registry of study patients who had had DXA scans. For patients with DRF, the contralateral radius was scanned and BMD, T scores (used to define bone status as normal, osteopenic, or osteoporotic), and radius width were recorded. Generally, side-to-side (left-right) differences in bone size and BMD are small and, hence, the contralateral radius was considered a surrogate for bone status of the fractured radius. Apparently healthy women without fractures were used as race-, age-, and BMI-matched controls. Results Premenopausal women < 49 years of age (mean age, 38 years) with DRF had significanty smaller radii width compared to matched controls. Mean radius BMD was in the normal range. As a group, the cohort was overweight based on mean BMI. Postmenopausal women > 50 years (mean age, 64 years) with DRF also had low radius width, but in contrast to the first group, this group had low peripheral and central BMD. Conclusions Women with DRF had contralateral and presumably fractured radii of bone width smaller than matched controls. As a group, these women were also overweight based on BMI. The smaller radius width may increase the risk for fracture irrespective of BMD, especially since larger body size would result in greater inertial force when falling while ambulating. PMID- 29468106 TI - A Case of Acute Left Main Coronary Obstruction Following Transcatheter Aortic Valve Implantation. AB - Transcatheter aortic valve implantation (TAVI) is a highly effective procedure in selected patients with severe degenerative aortic valve stenosis at high risk for conventional surgery. Coronary occlusion is a periprocedural life-threatening complication that despite its low frequency (?1%) is poorly predictable and requires immediate diagnosis and treatment. Herein, we report a coronary obstruction after transcatheter implantation of valve prosthesis, followed by coronary intervention with successful recanalization. PMID- 29468107 TI - Contrast-Enhanced Ultrasound-Guided Radiofrequency Ablation of Renal Tumors. AB - Although only limited long-term studies evaluating thermal ablation of renal masses have been performed, it appears that thermal ablation has a comparable 5 year success rate to that of partial or total nephrectomy. This technique is often used in patients who are not good candidates for partial or total nephrectomy. Contrast-enhanced ultrasound (CEUS) has been recently approved by the Food and Drug Administration for characterization of focal liver lesions in adults and pediatric patients. CEUS can be used off label for renal applications and has been used for years in Europe and Asia. It has several advantages over contrast-enhanced computed tomography for use as the technique to guide and evaluate efficacy of thermal ablation of renal masses. These include the ability to visualize small amounts of enhancement, repeat dosing to evaluate efficacy of an ablation during a procedure, thin slice thickness, and real-time visualization. Ultrasound contrast is also non-nephrotoxic and non-hepatotoxic, allowing evaluation of patients with renal insufficiency. This article reviews the use of CEUS for the guidance and follow-up of thermal ablative procedures of renal masses. PMID- 29468108 TI - Nivolumab in Renal Cell Carcinoma: Current Trends and Future Perspectives. AB - Targeted agents form the backbone of most therapeutic strategies in advanced renal cell carcinoma (aRCC) but ultimately resistance develops and toxicity often leads to discontinuation of treatment, limiting the clinical benefits of these treatments. Nivolumab, a fully human IgG4 anti-PD-1 antibody, selectively blocks the interaction between PD-1 and its ligands PD-L1 and PD-L2 and provides a novel therapy option for patients with aRCC. In 2015, the pivotal phase III study CheckMate 025 led to the Food and Drug Administration approval of nivolumab in patients with aRCC who had received prior anti-angiogenic therapy, and in 2017, the phase III study CheckMate 214 showed that combined immunotherapy with nivolumab plus ipilimumab resulted in greater objective response rate and prolonged progression-free survival when compared with sunitinib in intermediate- and poor-risk patients with previously untreated aRCC. Early studies of nivolumab in association with anti-angiogenic therapy have generated enthusiasm and multiple combination trials are ongoing. PMID- 29468109 TI - Metabolic engineering of Escherichia coli for the biosynthesis of 2-pyrrolidone. AB - 2-Pyrrolidone is a valuable bulk chemical with myriad applications as a solvent, polymer precursor and active pharmaceutical intermediate. A novel 2-pyrrolidone synthase, ORF27, from Streptomyces aizunensis was identified to catalyze the ring closing dehydration of gamma-aminobutyrate. ORF27's tendency to aggregate was resolved by expression at low temperature and fusion to the maltose binding protein (MBP). Recombinant Escherichia coli was metabolically engineered for the production of 2-pyrrolidone from glutamate by expressing both the genes encoding GadB, a glutamate decarboxylase, and ORF27. Incorporation of a GadB mutant lacking H465 and T466, GadB_DeltaHT, improved the efficiency of one-pot 2 pyrrolidone biosynthesis in vivo. When the recombinant E. coli strain expressing the E. coli GadB_DeltaHT mutant and the ORF27-MBP fusion was cultured in ZYM-5052 medium containing 9 g/L of l-glutamate, 7.7 g/L of l-glutamate was converted to 1.1 g/L of 2-pyrrolidone within 31 h, achieving 25% molar yield from the consumed substrate. PMID- 29468110 TI - Hyaluronan production and molecular weight is enhanced in pathway-engineered strains of lactate dehydrogenase-deficient Lactococcus lactis. AB - The potential advantages of hyaluronic acid (HA) production by metabolically engineered Lactococcus lactis is constrained by the lower molecular weight and yield of HA obtained in these strains, compared to natural producers. Earlier studies have correlated lower HA yield with excessive lactate production in L. lactis cultures (Chauhan et al., 2014). In the present study, a three-fold increase was observed in the amount as well as molecular weight of HA produced by recombinant ldh-mutant L. lactis strains. The diversion from lactate production in the ldh-mutant strains resulted in excess ethanol and acetoin production and higher NAD+/NADH ratio in these cultures. The initial NAD+/NADH ratio showed a positive correlation with HA molecular weight as well as with the HA-precursor ratio (UDP-GlcUA/UDP-GlcNAc). The influence of NAD+/NADH ratio on regulation of the concerned metabolic pathways was assessed by transcriptional analysis of key genes having putative binding sites of the NADH-binding transcriptional factor, Rex. PMID- 29468111 TI - Conversion of levoglucosan and cellobiosan by Pseudomonas putida KT2440. AB - Pyrolysis offers a straightforward approach for the deconstruction of plant cell wall polymers into bio-oil. Recently, there has been substantial interest in bio oil fractionation and subsequent use of biological approaches to selectively upgrade some of the resulting fractions. A fraction of particular interest for biological upgrading consists of polysaccharide-derived substrates including sugars and sugar dehydration products such as levoglucosan and cellobiosan, which are two of the most abundant pyrolysis products of cellulose. Levoglucosan can be converted to glucose-6-phosphate through the use of a levoglucosan kinase (LGK), but to date, the mechanism for cellobiosan utilization has not been demonstrated. Here, we engineer the microbe Pseudomonas putida KT2440 to use levoglucosan as a sole carbon and energy source through LGK integration. Moreover, we demonstrate that cellobiosan can be enzymatically converted to levoglucosan and glucose with beta-glucosidase enzymes from both Glycoside Hydrolase Family 1 and Family 3. beta-glucosidases are commonly used in both natural and industrial cellulase cocktails to convert cellobiose to glucose to relieve cellulase product inhibition and to facilitate microbial uptake of glucose. Using an exogenous beta glucosidase, we demonstrate that the engineered strain of P. putida can grow on levoglucosan up to 60 g/L and can also utilize cellobiosan. Overall, this study elucidates the biological pathway to co-utilize levoglucosan and cellobiosan, which will be a key transformation for the biological upgrading of pyrolysis derived substrates. PMID- 29468112 TI - Promiscuous plasmid replication in thermophiles: Use of a novel hyperthermophilic replicon for genetic manipulation of Clostridium thermocellum at its optimum growth temperature. AB - Clostridium thermocellum is a leading candidate for the consolidated bioprocessing of lignocellulosic biomass for the production of fuels and chemicals. A limitation to the engineering of this strain is the availability of stable replicating plasmid vectors for homologous and heterologous expression of genes that provide improved and/or novel pathways for fuel production. Current vectors relay on replicons from mesophilic bacteria and are not stable at the optimum growth temperature of C. thermocellum. To develop more thermostable genetic tools for C. thermocellum, we constructed vectors based on the hyperthermophilic Caldicellulosiruptor bescii replicon pBAS2. Autonomously replicating shuttle vectors based on pBAS2 reproducibly transformed C. thermocellum at 60 degrees C and were maintained in multiple copy. Promoters, selectable markers and plasmid replication proteins from C. bescii were functional in C. thermocellum. Phylogenetic analyses of the proteins contained on pBAS2 revealed that the replication initiation protein RepL is unique among thermophiles. These results suggest that pBAS2 may be a broadly useful replicon for other thermophilic Firmicutes. PMID- 29468114 TI - Mitochondrial targeting increases specific activity of a heterologous valine assimilation pathway in Saccharomyces cerevisiae. AB - Bio-based isobutantol is a sustainable 'drop in' substitute for petroleum-based fuels. However, well-studied production routes, such as the Ehrlich pathway, have yet to be commercialized despite more than a century of research. The more versatile bacterial valine catabolism may be a competitive alternate route producing not only an isobutanol precursor but several carboxylic acids with applications as biomonomers, and building blocks for other advanced biofuels. Here, we transfer the first two committed steps of the pathway from pathogenic Pseudomonas aeruginosa PAO1 to yeast to evaluate their activity in a safer model organism. Genes encoding the heteroligomeric branched chain keto-acid dehydrogenase (BCKAD; bkdA1, bkdA2, bkdB, lpdV), and the homooligomeric acyl-CoA dehydrogenase (ACD; acd1) were tagged with fluorescence epitopes and targeted for expression in either the mitochondria or cytoplasm of S. cerevisiae. We verified the localization of our constructs with confocal fluorescence microscopy before measuring the activity of tag-free constructs. Despite reduced heterologous expression of mitochondria-targeted enzymes, their specific activities were significantly improved with total enzyme activities up to 138% greater than those of enzymes expressed in the cytoplasm. In total, our results demonstrate that the choice of protein localization in yeast has significant impact on heterologous activity, and suggests a new path forward for isobutanol production. PMID- 29468113 TI - Interaction of storage carbohydrates and other cyclic fluxes with central metabolism: A quantitative approach by non-stationary 13C metabolic flux analysis. AB - 13C labeling experiments in aerobic glucose limited cultures of Saccharomyces cerevisiae at four different growth rates (0.054; 0.101, 0.207, 0.307 h-1) are used for calculating fluxes that include intracellular cycles (e.g., storage carbohydrate cycles, exchange fluxes with amino acids), which are rearranged depending on the growth rate. At low growth rates the impact of the storage carbohydrate recycle is relatively more significant than at high growth rates due to a higher concentration of these materials in the cell (up to 560-fold) and higher fluxes relative to the glucose uptake rate (up to 16%). Experimental observations suggest that glucose can be exported to the extracellular space, and that its source is related to storage carbohydrates, most likely via the export and subsequent extracellular breakdown of trehalose. This hypothesis is strongly supported by 13C-labeling experimental data, measured extracellular trehalose, and the corresponding flux estimations. PMID- 29468115 TI - An optimized method for accurate quantification of cell migration using human small intestine cells. AB - Quantifying the ability of a compound to modulate cell migration rate is a crucial part of many studies including those on chemotaxis, wound healing and cancer metastasis. Existing migration assays all have their strengths and weaknesses. The "scratch" assay is the most widely used because it seems appealingly simple and inexpensive. However, the scratch assay has some important limitations, as the tool introducing the "wound" might injure/stress the boundary cells and/or harm underlying matrix coatings, which in both cases will affect cell migration. This described method is a Cell Exclusion Zone Assay, in which cell-free areas are created by growing cells around removable silicone stoppers. Upon appropriate staining with fluorescent dyes and microscopically visualizing the monolayers, the migration rate is then quantified by counting the cells (nuclei) intruding the void area left by the silicone insert. In the current study human small intestine epithelial cells were seeded on a physiological substrate matrix to produce collectively migrating monolayers. Different substrates were tested to determine the optimal surface for enterocyte adherence and migration and morphological changes monitored. Recombinant human epidermal growth factor and osteopontin purified from urine were tested to see if the established migration assay produces accurate and reliable migration data with human small intestine cells. The obtained data accurately confirmed that the two bioactive proteins modulate cellular migration in a dose-dependent manner. The presented assay can likely be converted for use with other adherent cell lines or substrate matrices and allows for high throughput, while cost is kept low and versatility high. Co-staining can be applied in order to assay for cell death, different cell types, cell stress and others allowing intricate analysis of migration rate of mixed populations and correction for cell viability. PMID- 29468116 TI - Acidithiobacillus ferrooxidans's comprehensive model driven analysis of the electron transfer metabolism and synthetic strain design for biomining applications. AB - Acidithiobacillus ferrooxidans is a gram-negative chemolithoautotrophic gamma proteobacterium. It typically grows at an external pH of 2 using the oxidation of ferrous ions by oxygen, producing ferric ions and water, while fixing carbon dioxide from the environment. A. ferrooxidans is of great interest for biomining and environmental applications, as it can process mineral ores and alleviate the negative environmental consequences derived from the mining processes. In this study, the first genome-scale metabolic reconstruction of A. ferrooxidans ATCC 23270 was generated (iMC507). A total of 587 metabolic and transport/exchange reactions, 507 genes and 573 metabolites organized in over 42 subsystems were incorporated into the model. Based on a new genetic algorithm approach, that integrates flux balance analysis, chemiosmotic theory, and physiological data, the proton translocation stoichiometry for a number of enzymes and maintenance parameters under aerobic chemolithoautotrophic conditions using three different electron donors were estimated. Furthermore, a detailed electron transfer and carbon flux distributions during chemolithoautotrophic growth using ferrous ion, tetrathionate and thiosulfate were determined and reported. Finally, 134 growth coupled designs were calculated that enables Extracellular Polysaccharide production. iMC507 serves as a knowledgebase for summarizing and categorizing the information currently available for A. ferrooxidans and enables the understanding and engineering of Acidithiobacillus and similar species from a comprehensive model-driven perspective for biomining applications. PMID- 29468117 TI - Dynamics of benzoate metabolism in Pseudomonas putida KT2440. AB - Soil microorganisms mineralize lignin-derived aromatic carbon sources using oxidative catabolic pathways, such as the beta-ketoadipate pathway. Although this aromatic pathway is one of the best-studied pathways in biochemistry, the complete pathway, including its regulation by aromatic carbon sources, has not been integrated into the metabolic network. In particular, information about the in vivo operation (e.g., kinetics and flux capacity) of the pathway is lacking. In this contribution, we use kinetic modeling and thermodynamic analysis to evaluate the in vivo operation of this key aromatic multi-step pathway. The resulting ab initio deterministic model of benzoate degradation via the beta ketoadipate (ortho-cleavage) pathway in Pseudomonas putida KT2440 is presented. The kinetic model includes mechanistic rate expressions for the enzymes and transport processes. The design and experimental validation of the model are driven by data generated from short-term perturbation experiments in a benzoate limited continuous culture. The results of rigorous modeling of the in vivo dynamics provide strong support for flux regulation by the benzoate transporter and the enzymes forming and cleaving catechol. Revisiting the beta-ketoadipate pathway might be valuable for applications in different fields, such as biochemistry and metabolic engineering, that use lignin monomers as a carbon source. PMID- 29468118 TI - Enhancing muconic acid production from glucose and lignin-derived aromatic compounds via increased protocatechuate decarboxylase activity. AB - The conversion of biomass-derived sugars and aromatic molecules to cis,cis muconic acid (referred to hereafter as muconic acid or muconate) has been of recent interest owing to its facile conversion to adipic acid, an important commodity chemical. Metabolic routes to produce muconate from both sugars and many lignin-derived aromatic compounds require the use of a decarboxylase to convert protocatechuate (PCA, 3,4-dihydroxybenzoate) to catechol (1,2 dihydroxybenzene), two central aromatic intermediates in this pathway. Several studies have identified the PCA decarboxylase as a metabolic bottleneck, causing an accumulation of PCA that subsequently reduces muconate production. A recent study showed that activity of the PCA decarboxylase is enhanced by co-expression of two genetically associated proteins, one of which likely produces a flavin derived cofactor utilized by the decarboxylase. Using entirely genome-integrated gene expression, we have engineered Pseudomonas putida KT2440-derived strains to produce muconate from either aromatic molecules or sugars and demonstrate in both cases that co-expression of these decarboxylase associated proteins reduces PCA accumulation and enhances muconate production relative to strains expressing the PCA decarboxylase alone. In bioreactor experiments, co-expression increased the specific productivity (mg/g cells/h) of muconate from the aromatic lignin monomer p-coumarate by 50% and resulted in a titer of >15 g/L. In strains engineered to produce muconate from glucose, co-expression more than tripled the titer, yield, productivity, and specific productivity, with the best strain producing 4.92+/ 0.48 g/L muconate. This study demonstrates that overcoming the PCA decarboxylase bottleneck can increase muconate yields from biomass-derived sugars and aromatic molecules in industrially relevant strains and cultivation conditions. PMID- 29468119 TI - Improved sugar-free succinate production by Synechocystis sp. PCC 6803 following identification of the limiting steps in glycogen catabolism. AB - Succinate produced by microorganisms can replace currently used petroleum-based succinate but typically requires mono- or poly-saccharides as a feedstock. The cyanobacterium Synechocystis sp. PCC6803 can produce organic acids such as succinate from CO2 not supplemented with sugars under dark anoxic conditions using an unknown metabolic pathway. The TCA cycle in cyanobacteria branches into oxidative and reductive routes. Time-course analyses of the metabolome, transcriptome and metabolic turnover described here revealed dynamic changes in the metabolism of Synechocystis sp. PCC6803 cultivated under dark anoxic conditions, allowing identification of the carbon flow and rate-limiting steps in glycogen catabolism. Glycogen biosynthesized from CO2 assimilated during periods of light exposure is catabolized to succinate via glycolysis, the anaplerotic pathway, and the reductive TCA cycle under dark anoxic conditions. Expression of the phosphoenolpyruvate (PEP) carboxylase gene (ppc) was identified as a rate limiting step in succinate biosynthesis and this rate limitation was alleviated by ppc overexpression, resulting in improved succinate excretion. The sugar-free succinate production was further enhanced by the addition of bicarbonate. In vivo labeling with NaH13CO3 clearly showed carbon incorporation into succinate via the anaplerotic pathway. Bicarbonate is in equilibrium with CO2. Succinate production by Synechocystis sp. PCC6803 therefore holds significant promise for CO2 capture and utilization. PMID- 29468120 TI - The Saccharomyces cerevisiae pheromone-response is a metabolically active stationary phase for bio-production. AB - The growth characteristics and underlying metabolism of microbial production hosts are critical to the productivity of metabolically engineered pathways. Production in parallel with growth often leads to biomass/bio-product competition for carbon. The growth arrest phenotype associated with the Saccharomyces cerevisiae pheromone-response is potentially an attractive production phase because it offers the possibility of decoupling production from population growth. However, little is known about the metabolic phenotype associated with the pheromone-response, which has not been tested for suitability as a production phase. Analysis of extracellular metabolite fluxes, available transcriptomic data, and heterologous compound production (para-hydroxybenzoic acid) demonstrate that a highly active and distinct metabolism underlies the pheromone-response. These results indicate that the pheromone-response is a suitable production phase, and that it may be useful for informing synthetic biology design principles for engineering productive stationary phase phenotypes. PMID- 29468121 TI - Improving the flux distributions simulated with genome-scale metabolic models of Saccharomyces cerevisiae. AB - Genome-scale metabolic models (GEMs) can be used to evaluate genotype-phenotype relationships and their application to microbial strain engineering is increasing in popularity. Some of the algorithms used to simulate the phenotypes of mutant strains require the determination of a wild-type flux distribution. However, the accuracy of this reference, when calculated with flux balance analysis, has not been studied in detail before. Here, the wild-type simulations of selected GEMs for Saccharomyces cerevisiae have been analysed and most of the models tested predicted erroneous fluxes in central pathways, especially in the pentose phosphate pathway. Since the problematic fluxes were mostly related to areas of the metabolism consuming or producing NADPH/NADH, we have manually curated all reactions including these cofactors by forcing the use of NADPH/NADP+ in anabolic reactions and NADH/NAD+ for catabolic reactions. The curated models predicted more accurate flux distributions and performed better in the simulation of mutant phenotypes. PMID- 29468122 TI - A genetic screen for increasing metabolic flux in the isoprenoid pathway of Saccharomyces cerevisiae: Isolation of SPT15 mutants using the screen. AB - A genetic screen to identify mutants that can increase flux in the isoprenoid pathway of yeast has been lacking. We describe a carotenoid-based visual screen built with the core carotenogenic enzymes from the red yeast Rhodosporidium toruloides. Enzymes from this yeast displayed the required, higher capacity in the carotenoid pathway. The development also included the identification of the metabolic bottlenecks, primarily phytoene dehydrogenase, that was subjected to a directed evolution strategy to yield more active mutants. To further limit phytoene pools, a less efficient version of GGPP synthase was employed. The screen was validated with a known flux increasing gene, tHMG1. New mutants in the TATA binding protein SPT15 were isolated using this screen that increased the yield of carotenoids, and an alternate isoprenoid, alpha-Farnesene confirming increase in overall flux. The findings indicate the presence of previously unknown links to the isoprenoid pathway that can be uncovered using this screen. PMID- 29468123 TI - Molecular Cloning Designer Simulator (MCDS): All-in-one molecular cloning and genetic engineering design, simulation and management software for complex synthetic biology and metabolic engineering projects. AB - Molecular Cloning Designer Simulator (MCDS) is a powerful new all-in-one cloning and genetic engineering design, simulation and management software platform developed for complex synthetic biology and metabolic engineering projects. In addition to standard functions, it has a number of features that are either unique, or are not found in combination in any one software package: (1) it has a novel interactive flow-chart user interface for complex multi-step processes, allowing an integrated overview of the whole project; (2) it can perform a user defined workflow of cloning steps in a single execution of the software; (3) it can handle multiple types of genetic recombineering, a technique that is rapidly replacing classical cloning for many applications; (4) it includes experimental information to conveniently guide wet lab work; and (5) it can store results and comments to allow the tracking and management of the whole project in one platform. MCDS is freely available from https://mcds.codeplex.com. PMID- 29468124 TI - The impact of respiration and oxidative stress response on recombinant alpha amylase production by Saccharomyces cerevisiae. AB - Studying protein production is important for fundamental research on cell biology and applied research for biotechnology. Yeast Saccharomyces cerevisiae is an attractive workhorse for production of recombinant proteins as it does not secrete many endogenous proteins and it is therefore easy to purify a secreted product. However, recombinant production at high rates represents a significant metabolic burden for the yeast cells, which results in oxidative stress and ultimately affects the protein production capacity. Here we describe a method to reduce the overall oxidative stress by overexpressing the endogenous HAP1 gene in a S. cerevisiae strain overproducing recombinant alpha-amylase. We demonstrate how Hap1p can activate a set of oxidative stress response genes and meanwhile contribute to increase the metabolic rate of the yeast strains, therefore mitigating the negative effect of the ROS accumulation associated to protein folding and hence increasing the production capacity during batch fermentations. PMID- 29468125 TI - Enhanced fatty acid production in engineered chemolithoautotrophic bacteria using reduced sulfur compounds as energy sources. AB - Chemolithoautotrophic bacteria that oxidize reduced sulfur compounds, such as H2S, while fixing CO2 are an untapped source of renewable bioproducts from sulfide-laden waste, such as municipal wastewater. In this study, we report engineering of the chemolithoautotrophic bacterium Thiobacillus denitrificans to produce up to 52-fold more fatty acids than the wild-type strain when grown with thiosulfate and CO2. A modified thioesterase gene from E. coli ('tesA) was integrated into the T. denitrificans chromosome under the control of Pkan or one of two native T. denitrificans promoters. The relative strength of the two native promoters as assessed by fatty acid production in engineered strains was very similar to that assessed by expression of the cognate genes in the wild-type strain. This proof-of-principle study suggests that engineering sulfide-oxidizing chemolithoautotrophic bacteria to overproduce fatty acid-derived products merits consideration as a technology that could simultaneously produce renewable fuels/chemicals as well as cost-effectively remediate sulfide-contaminated wastewater. PMID- 29468127 TI - Quantifying complexity in metabolic engineering using the LASER database. AB - We previously introduced the LASER database (Learning Assisted Strain EngineeRing, https://bitbucket.org/jdwinkler/laser_release) (Winkler et al. 2015) to serve as a platform for understanding past and present metabolic engineering practices. Over the past year, LASER has been expanded by 50% to include over 600 engineered strains from 450 papers, including their growth conditions, genetic modifications, and other information in an easily searchable format. Here, we present the results of our efforts to use LASER as a means for defining the complexity of a metabolic engineering "design". We evaluate two complexity metrics based on the concepts of construction difficulty and novelty. No correlation is observed between expected product yield and complexity, allowing minimization of complexity without a performance trade-off. We envision the use of such complexity metrics to filter and prioritize designs prior to implementation of metabolic engineering efforts, thereby potentially reducing the time, labor, and expenses of large-scale projects. Possible future developments based on an expanding LASER database are then discussed. PMID- 29468126 TI - Computational metabolic engineering strategies for growth-coupled biofuel production by Synechocystis. AB - Chemical and fuel production by photosynthetic cyanobacteria is a promising technology but to date has not reached competitive rates and titers. Genome-scale metabolic modeling can reveal limitations in cyanobacteria metabolism and guide genetic engineering strategies to increase chemical production. Here, we used constraint-based modeling and optimization algorithms on a genome-scale model of Synechocystis PCC6803 to find ways to improve productivity of fermentative, fatty acid, and terpene-derived fuels. OptGene and MOMA were used to find heuristics for knockout strategies that could increase biofuel productivity. OptKnock was used to find a set of knockouts that led to coupling between biofuel and growth. Our results show that high productivity of fermentation or reversed beta oxidation derived alcohols such as 1-butanol requires elimination of NADH sinks, while terpenes and fatty-acid based fuels require creating imbalances in intracellular ATP and NADPH production and consumption. The FBA-predicted productivities of these fuels are at least 10-fold higher than those reported so far in the literature. We also discuss the physiological and practical feasibility of implementing these knockouts. This work gives insight into how cyanobacteria could be engineered to reach competitive biofuel productivities. PMID- 29468128 TI - The expression of glycerol facilitators from various yeast species improves growth on glycerol of Saccharomyces cerevisiae. AB - Glycerol is an abundant by-product during biodiesel production and additionally has several assets compared to sugars when used as a carbon source for growing microorganisms in the context of biotechnological applications. However, most strains of the platform production organism Saccharomyces cerevisiae grow poorly in synthetic glycerol medium. It has been hypothesized that the uptake of glycerol could be a major bottleneck for the utilization of glycerol in S. cerevisiae. This species exclusively relies on an active transport system for glycerol uptake. This work demonstrates that the expression of predicted glycerol facilitators (Fps1 homologues) from superior glycerol-utilizing yeast species such as Pachysolen tannophilus, Komagataella pastoris, Yarrowia lipolytica and Cyberlindnera jadinii significantly improves the growth performance on glycerol of the previously selected glycerol-consuming S. cerevisiae wild-type strain (CBS 6412-13A). The maximum specific growth rate increased from 0.13 up to 0.18 h-1 and a biomass yield coefficient of 0.56 gDW/gglycerol was observed. These results pave the way for exploiting the assets of glycerol in the production of fuels, chemicals and pharmaceuticals based on baker's yeast. PMID- 29468129 TI - Conversion and assimilation of furfural and 5-(hydroxymethyl)furfural by Pseudomonas putida KT2440. AB - The sugar dehydration products, furfural and 5-(hydroxymethyl)furfural (HMF), are commonly formed during high-temperature processing of lignocellulose, most often in thermochemical pretreatment, liquefaction, or pyrolysis. Typically, these two aldehydes are considered major inhibitors in microbial conversion processes. Many microbes can convert these compounds to their less toxic, dead-end alcohol counterparts, furfuryl alcohol and 5-(hydroxymethyl)furfuryl alcohol. Recently, the genes responsible for aerobic catabolism of furfural and HMF were discovered in Cupriavidus basilensis HMF14 to enable complete conversion of these compounds to the TCA cycle intermediate, 2-oxo-glutarate. In this work, we engineer the robust soil microbe, Pseudomonas putida KT2440, to utilize furfural and HMF as sole carbon and energy sources via complete genomic integration of the 12 kB hmf gene cluster previously reported from Burkholderia phytofirmans. The common intermediate, 2-furoic acid, is shown to be a bottleneck for both furfural and HMF metabolism. When cultured on biomass hydrolysate containing representative amounts of furfural and HMF from dilute-acid pretreatment, the engineered strain outperforms the wild type microbe in terms of reduced lag time and enhanced growth rates due to catabolism of furfural and HMF. Overall, this study demonstrates that an approach for biological conversion of furfural and HMF, relative to the typical production of dead-end alcohols, enables both enhanced carbon conversion and substantially improves tolerance to hydrolysate inhibitors. This approach should find general utility both in emerging aerobic processes for the production of fuels and chemicals from biomass-derived sugars and in the biological conversion of high-temperature biomass streams from liquefaction or pyrolysis where furfural and HMF are much more abundant than in biomass hydrolysates from pretreatment. PMID- 29468130 TI - Synechocystis PCC 6803 overexpressing RuBisCO grow faster with increased photosynthesis. AB - The ribulose-1,5-bisphosphate (RuBP) oxygenation reaction catalyzed by Ribulose 1,5-bisphosphate carboxylase/oxygenase (RuBisCO) is competing with carboxylation, being negative for both energy and carbon balances in photoautotrophic organisms. This makes RuBisCO one of the bottlenecks for oxygenic photosynthesis and carbon fixation. In this study, RuBisCO was overexpressed in the unicellular cyanobacterium Synechocystis PCC 6803. Relative RuBisCO levels in the engineered strains FL50 and FL52 increased 2.1 times and 1.4 times, respectively, and both strains showed increased growth, photosynthesis and in vitro RuBisCO activity. The oxygen evolution rate increased by 54% and 42% on per chlorophyll basis, while the in vitro RuBisCO activity increased by 52% and 8.6%, respectively. The overexpressed RuBisCO were tagged with a FLAG tag, in strain FL50 on the N terminus of the large subunit while in strain FL52 on the C terminus of the small subunit. The presence of a FLAG tag enhanced transcription of the genes encoding RuBisCO, and, with high possibility, also enhanced the initiation of translation or stability of the enzyme. However, when using a streptavidin-binding tag II (strep-tag II), we did not observe a similar effect. Tagged RuBisCO offers an opportunity for further studying RuBisCO expression and stability. Increased levels of RuBisCO can further improve photosynthesis and growth in the cyanobacterium Synechocystis PCC 6803 under certain growth conditions. PMID- 29468131 TI - Selection Finder (SelFi): A computational metabolic engineering tool to enable directed evolution of enzymes. AB - Directed evolution of enzymes consists of an iterative process of creating mutant libraries and choosing desired phenotypes through screening or selection until the enzymatic activity reaches a desired goal. The biggest challenge in directed enzyme evolution is identifying high-throughput screens or selections to isolate the variant(s) with the desired property. We present in this paper a computational metabolic engineering framework, Selection Finder (SelFi), to construct a selection pathway from a desired enzymatic product to a cellular host and to couple the pathway with cell survival. We applied SelFi to construct selection pathways for four enzymes and their desired enzymatic products xylitol, D-ribulose-1,5-bisphosphate, methanol, and aniline. Two of the selection pathways identified by SelFi were previously experimentally validated for engineering Xylose Reductase and RuBisCO. Importantly, SelFi advances directed evolution of enzymes as there is currently no known generalized strategies or computational techniques for identifying high-throughput selections for engineering enzymes. PMID- 29468133 TI - Palliative surgery for Krukenberg tumors - 12-year experience and review of the literature. AB - AIM: To determine the clinical characteristics of patients undergoing palliative surgery for Krukenberg tumors, including disease presentation, outcomes, and prognostic factors. METHODS: This was a retrospective clinical study of all patients who underwent palliative surgery for Krukenberg tumors between January 2004 and December 2015. Patient information was obtained from inpatient and outpatient case notes as well as the hospital electronic records. Patients who underwent potentially curative resection, and patients with Krukenberg tumors who did not undergo surgery were also excluded from the study. Palliative surgery was defined as those performed for either alleviation of symptoms or for asymptomatic patients for whom surgical removal of the tumors were deemed necessary following a multidisciplinary consensus. Tumors were diagnosed pre-operatively by computed tomography scans and all had histologic confirmation of the surgical specimens. RESULTS: Over the study duration, 38 female patients underwent palliative surgery for Krukenberg tumors at our institution. Mean age was 54.2 +/- 11.7 years. The colon was the most frequent primary source of metastases (n = 21) followed by the stomach (n = 4). Prophylactic palliative surgery was performed for eight (21.1%) asymptomatic patients. Median post-operative length of stay was 8 d (IQR 6-12 d). Five patients (13.2%) experienced post-operative complications, although high grade morbidity was only seen in one patient (2.6%). Median overall survival from surgery was 17 mo (95%CI: 12.1-21.9) at a median follow-up duration of 12 mo (IQR 8-17 mo). The median survival was shorter for patients who underwent emergency surgery, younger patients, those with a colorectal primary, larger tumors, or synchronous peritoneal or hepatic metastases. CONCLUSION: Palliative surgery for Krukenberg tumors can be performed safely with acceptable complication rates. Bilateral oophorectomy should be performed to prevent the risk of symptomatic contralateral tumors. PMID- 29468132 TI - Does low volume high-intensity interval training elicit superior benefits to continuous low to moderate-intensity training in cancer survivors? AB - AIM: To determine the impact of low volume high-intensity interval training (LVHIIT) and continuous low to moderate-intensity exercise training (CLMIT) on cardiovascular disease (CVD) risk and health outcomes in cancer survivors. METHODS: Sedentary cancer survivors (n = 75, aged 51 +/- 12 year) within 24 months of diagnosis, were randomised into three groups for 12 wk of LVHIIT (n = 25), CLMIT (n = 25) or control group (n = 25). The exercise intervention involved 36 sessions (three sessions per week). The LVHIIT group performed 7 x 30 s intervals (>= 85% predicted maximal heart rate) with a 60 s rest between intervals, and the CLMIT group performed continuous aerobic training for 20 min (<= 55% predicted maximal heart rate) on a stationary bike. Outcome variables were measured at baseline and at 12 weeks and analysed using a 3 x 2 (group x time) repeated measures ANCOVA to evaluate main and interaction effects. RESULTS: Significant improvements (time) were observed for seven of the 22 variables (ES 0.35-0.97, P <= 0.05). There was an interaction effect (P < 0.01) after 12 wk in the LVHIIT group for six-minute walk test (P < 0.01; d = 0.97; 95%CI: 0.36, 1.56; large), sit to stand test (P < 0.01; d = -0.83; 95%CI: -1.40, -0.22; large ) and waist circumference reduction (P = 0.01; d = -0.48; 95%CI: -1.10, 0.10; medium). An interaction effect (P < 0.01) was also observed for quality of life in both the LVHIIT (d = 1.11; 95%CI: 0.50, 1.72; large) and CLMIT (d = 0.57; 95%CI: 0.00, 1.20; moderate) compared with the control group (d = -0.15; 95%CI: -0.95, 0.65; trivial). CONCLUSION: Low-volume high-intensity training shows promise as an effective exercise prescription within the cancer population, showing greater improvements in cardio-respiratory fitness, lower body strength and waist circumference compared with traditional CLMIT and control groups. Both LVHIIT and CLMIT improved quality of life. A proposed benefit of LVHIIT is the short duration (3 min) of exercise required, which may entice more cancer survivors to participate in exercise, improving health outcomes and lowing the risk of CVD. PMID- 29468134 TI - Yttrium-90 microsphere selective internal radiation therapy for liver metastases following systemic chemotherapy and surgical resection for metastatic adrenocortical carcinoma. AB - Adrenocortical carcinoma (ACC) is a rare malignancy with generally poor outcomes and limited treatment options. While surgical resection can be curative for early local disease, most patients present with advanced ACC owing to nonspecific symptoms. For those patients, treatment options include systemic chemotherapy and locoregional therapies including radiofrequency ablation and transarterial chemoembolization. We present the first reported case of utilizing yttrium-90 microsphere selective internal radiation therapy (SIRT) in combination with first line EDP-M (Etoposide, Doxorubicin, Cisplatin, Mitotane) chemotherapy and debulking surgical primary tumor resection for treatment of metastatic ACC. Stable complete radiologic response has been maintained after twelve months with resolution of clinical symptoms. These findings prompt the need for further consideration and studies to elucidate the role of SIRT in combination with systemic and surgical treatment for metastatic ACC. PMID- 29468135 TI - Optimal surgical approach for the treatment of Quervains disease: A surgical anatomical study. AB - AIM: To determine which of the common used incision techniques has the lowest chance of iatrogenic damage to the nerves which at risk are the superficial branch of the radial nerve (SBRN) and the Lateral Antebrachial Cutaneous Nerve (LABCN). METHODS: Twenty embalmed arms were dissected and the course of the SBRN and the LABCN in each individual arm was marked and the distance between the two branches of the SBRN at the location of the First Extensor Compartment (FEC) was measured. This data was used as input in a visualization tool called Computer Assisted Anatomy Mapping (CASAM) to map the course of the nerves in each individual arm. RESULTS: This image visualizes that in 90% of the arms, one branch of the SBRN crosses the FEC and one branch runs volar to the compartment. The distance between the two branches was 7.8 mm at the beginning of the FEC and 10.2 mm at the end. Finally the angle of incision at which the chance of damage to the nerves is lowest, is 19.4 degrees volar to the radius. CONCLUSION: CASAM shows the complexity of the course of the SBRN over the FEC. None of the four widely used incision techniques has a significantly lower chance of iatrogenic nerve damage. Surgical skills are paramount to prevent iatrogenic nerve damage. PMID- 29468136 TI - Retinoic acid receptor beta promoter methylation and risk of cervical cancer. AB - Cervical cancer is one of the leading causes of death in women worldwide, particularly in developing countries. Human papillomavirus has been reported as one of the key etiologic factors in cervical carcinoma. Likewise, epigenetic aberrations have ability to regulate cancer pathogenesis and progression. Recent research suggested that methylation has been detected already at precancerous stages, which methylation markers may have significant value in cervical cancer screening. The retinoic acid receptor beta (RARbeta) gene, a potential tumor suppressor gene, is usually expressed in normal epithelial tissue. Methylation of CpG islands in the promoter region of the RARbeta gene has been found to be associated with the development of cervical cancer. To investigate whether RARbeta methylation is a potential biomarker that predicts the progression of invasive cancer, we reviewed 14 previously published articles related to RARbeta methylation. The majority of them demonstrated that the frequency of RARbeta promoter methylation was significantly correlated with the severity of cervical epithelium abnormalities. However, methylation of a single gene may not represent the best approach for predicting disease prognosis. Analyzing combinations of aberrant methylation of multiple genes may increase the sensitivity, and thus this approach may serve as a better tool for predicting disease prognosis. PMID- 29468137 TI - Identification of various cell culture models for the study of Zika virus. AB - AIM: To identify cell culture models supportive for Zika virus (ZIKV) replication. METHODS: Various human and non-human cell lines were infected with a defined amount of ZIKV Polynesia strain. Cells were analyzed 48 h post infection for the amount of intracellular and extracellular viral genomes and infectious viral particles by quantitative real-time PCR and virus titration assay. The extent of replication was monitored by immunofluorescence and western blot analysis by using Env and NS1 specific antibodies. Innate immunity was assayed by luciferase reporter assay and immunofluorescence analysis. RESULTS: All investigated cell lines except CHO cells supported infection, replication and release of ZIKV. While in infected A549 and Vero cells a pronounced cytopathic effect was observed COS7, 293T and Huh7.5 cells were most resistant. Although the analyzed cell lines released comparable amounts of viral genomes to the supernatant significant differences were found for the number of infectious viral particles. The neuronal cell lines N29.1 and SH-SY5Y released 100 times less infectious viral particles than Vero-, A549- or 293T-cells. However there is no strict correlation between the amount of produced viral particles and the induction of an interferon response in the analyzed cell lines. CONCLUSION: The investigated cell lines with their different tissue origins and diverging ZIKV susceptibility display a toolbox for ZIKV research.

AB - Hyperspectral imaging (HSI) is a non-invasive optical imaging modality that shows the potential to aid pathologists in breast cancer diagnoses cases. In this study, breast cancer tissues from different patients were imaged by a hyperspectral system to detect spectral differences between normal and breast cancer tissues. Tissue samples mounted on slides were identified from 10 different patients. Samples from each patient included both normal and ductal carcinoma tissue, both stained with hematoxylin and eosin stain and unstained. Slides were imaged using a snapshot HSI system, and the spectral reflectance differences were evaluated. Analysis of the spectral reflectance values indicated that wavelengths near 550 nm showed the best differentiation between tissue types. This information was used to train image processing algorithms using supervised and unsupervised data. The K-means method was applied to the hyperspectral data cubes, and successfully detected spectral tissue differences with sensitivity of 85.45%, and specificity of 94.64% with true negative rate of 95.8%, and false positive rate of 4.2%. These results were verified by ground truth marking of the tissue samples by a pathologist. In the hyperspectral image analysis, the image processing algorithm, K-means, shows the greatest potential for building a semi-automated system that could identify and sort between normal and ductal carcinoma in situ tissues.

The characteristic increase in glycolysis, i.e., Warburg effect, now considered as a hallmark, supports cancer in various ways. To attain such metabolic reshuffle, cancer cells preferentially re-express the M2 isoform of pyruvate kinase (PKM2, M2-PK) and alter its quaternary structure to generate less-active PKM2 dimers. The relatively inactive dimers cause the accumulation of glycolytic intermediates that are redirected into anabolic pathways. In addition, dimeric PKM2 also benefits cancer cells through various non-glycolytic moonlight functions, such as gene transcription, protein kinase activity, and redox balance. A large body of data have shown that several distinct posttranslation modifications (PTMs) regulate PKM2 in a way that benefits cancer growth, e.g., formation of PKM2 dimers. This review discusses the recent advancements in our understanding of various PTMs and the benefits they impart to the sustenance of cancer. Understanding the PTMs in PKM2 is crucial to assess their therapeutic potential and to design novel anticancer strategies.

AB - The Gram-negative bacterium, Helicobacter pylori, causes chronic gastritis, peptic ulcers, and gastric cancer in humans. Although the gastric epithelium is the primary site of H. pylori colonization, H. pylori can gain access to deeper tissues. Concurring with this notion, H. pylori has been found in the vicinity of endothelial cells in gastric submucosa. Endothelial cells play crucial roles in innate immune response, wound healing and tumorigenesis. This study examines the molecular mechanisms by which H. pylori interacts with and triggers inflammatory responses in endothelial cells. We observed that H. pylori infection of primary human endothelial cells stimulated secretion of the key inflammatory cytokines, interleukin-6 (IL-6) and interleukin-8 (IL-8). In particular, IL-8, a potent chemokine and angiogenic factor, was secreted by H. pylori-infected endothelial cells to levels ~10- to 20-fold higher than that typically observed in H. pylori infected gastric epithelial cells. These inflammatory responses were triggered by the H. pylori type IV secretion system (T4SS) and the T4SS-associated adhesin CagL, but not the translocation substrate CagA. Moreover, in contrast to integrin alpha5beta1 playing an essential role in IL-8 induction by H. pylori upon infection of gastric epithelial cells, both integrin alpha5beta1 and integrin alphavbeta3 were dispensable for IL-8 induction in H. pylori-infected endothelial cells. However, epidermal growth factor receptor (EGFR) is crucial for mediating the potent H. pylori-induced IL-8 response in endothelial cells. This study reveals a novel mechanism by which the H. pylori T4SS and its adhesin subunit, CagL, may contribute to H. pylori pathogenesis by stimulating the endothelial innate immune responses, while highlighting EGFR as a potential therapeutic target for controlling H. pylori-induced inflammation. PMID- 29468143 TI - Metagenomic Characterization of the Human Intestinal Microbiota in Fecal Samples from STEC-Infected Patients. AB - The human intestinal microbiota is a homeostatic ecosystem with a remarkable impact on human health and the disruption of this equilibrium leads to an increased susceptibility to infection by numerous pathogens. In this study, we used shotgun metagenomic sequencing and two different bioinformatic approaches, based on mapping of the reads onto databases and on the reconstruction of putative draft genomes, to investigate possible changes in the composition of the intestinal microbiota in samples from patients with Shiga Toxin-producing E. coli (STEC) infection compared to healthy and healed controls, collected during an outbreak caused by a STEC O26:H11 infection. Both the bioinformatic procedures used, produced similar result with a good resolution of the taxonomic profiles of the specimens. The stool samples collected from the STEC infected patients showed a lower abundance of the members of Bifidobacteriales and Clostridiales orders in comparison to controls where those microorganisms predominated. These differences seemed to correlate with the STEC infection although a flexion in the relative abundance of the Bifidobacterium genus, part of the Bifidobacteriales order, was observed also in samples from Crohn's disease patients, displaying a STEC unrelated dysbiosis. The metagenomics also allowed to identify in the STEC positive samples, all the virulence traits present in the genomes of the STEC O26 that caused the outbreak as assessed through isolation of the epidemic strain and whole genome sequencing. The results shown represent a first evidence of the changes occurring in the intestinal microbiota of children in the course of STEC infection and indicate that metagenomics may be a promising tool for the culture independent clinical diagnosis of the infection. PMID- 29468144 TI - Vaccine-Mediated Mechanisms Controlling Replication of Francisella tularensis in Human Peripheral Blood Mononuclear Cells Using a Co-culture System. AB - Cell-mediated immunity (CMI) is normally required for efficient protection against intracellular infections, however, identification of correlates is challenging and they are generally lacking. Francisella tularensis is a highly virulent, facultative intracellular bacterium and CMI is critically required for protection against the pathogen, but how this is effectuated in humans is poorly understood. To understand the protective mechanisms, we established an in vitro co-culture assay to identify how control of infection of F. tularensis is accomplished by human cells and hypothesized that the model will mimic in vivo immune mechanisms. Non-adherent peripheral blood mononuclear cells (PBMCs) were expanded with antigen and added to cultures with adherent PBMC infected with the human vaccine strain, LVS, or the highly virulent SCHU S4 strain. Intracellular numbers of F. tularensis was followed for 72 h and secreted and intracellular cytokines were analyzed. Addition of PBMC expanded from naive individuals, i.e., those with no record of immunization to F. tularensis, generally resulted in little or no control of intracellular bacterial growth, whereas addition of PBMC from a majority of F. tularensis-immune individuals executed static and sometimes cidal effects on intracellular bacteria. Regardless of infecting strain, statistical differences between the two groups were significant, P < 0.05. Secretion of 11 cytokines was analyzed after 72 h of infection and significant differences with regard to secretion of IFN-gamma, TNF, and MIP-1beta was observed between immune and naive individuals for LVS-infected cultures. Also, in LVS-infected cultures, CD4 T cells from vaccinees, but not CD8 T cells, showed significantly higher expression of IFN-gamma, MIP-1beta, TNF, and CD107a than cells from naive individuals. The co-culture system appears to identify correlates of immunity that are relevant for the understanding of mechanisms of the protective host immunity to F. tularensis.

PMID- 29468141 TI - Impact of the Gut Microbiota on Intestinal Immunity Mediated by Tryptophan Metabolism. AB - The gut microbiota influences the health of the host, especially with regard to gut immune homeostasis and the intestinal immune response. In addition to serving as a nutrient enhancer, L-tryptophan (Trp) plays crucial roles in the balance between intestinal immune tolerance and gut microbiota maintenance. Recent discoveries have underscored that changes in the microbiota modulate the host immune system by modulating Trp metabolism. Moreover, Trp, endogenous Trp metabolites (kynurenines, serotonin, and melatonin), and bacterial Trp metabolites (indole, indolic acid, skatole, and tryptamine) have profound effects on gut microbial composition, microbial metabolism, the host's immune system, the host-microbiome interface, and host immune system-intestinal microbiota interactions. The aryl hydrocarbon receptor (AhR) mediates the regulation of intestinal immunity by Trp metabolites (as ligands of AhR), which is beneficial for immune homeostasis. Among Trp metabolites, AhR ligands consist of endogenous metabolites, including kynurenine, kynurenic acid, xanthurenic acid, and cinnabarinic acid, and bacterial metabolites, including indole, indole propionic acid, indole acetic acid, skatole, and tryptamine. Additional factors, such as aging, stress, probiotics, and diseases (spondyloarthritis, irritable bowel syndrome, inflammatory bowel disease, colorectal cancer), which are associated with variability in Trp metabolism, can influence Trp-microbiome-immune system interactions in the gut and also play roles in regulating gut immunity. This review clarifies how the gut microbiota regulates Trp metabolism and identifies the underlying molecular mechanisms of these interactions. Increased mechanistic insight into how the microbiota modulates the intestinal immune system through Trp metabolism may allow for the identification of innovative microbiota-based diagnostics, as well as appropriate nutritional supplementation of Trp to prevent or alleviate intestinal inflammation. Moreover, this review provides new insight regarding the influence of the gut microbiota on Trp metabolism. Additional comprehensive analyses of targeted Trp metabolites (including endogenous and bacterial metabolites) are essential for experimental preciseness, as the influence of the gut microbiota cannot be neglected, and may explain contradictory results in the literature. PMID- 29468146 TI - Antioxidant Phytochemicals in Fresh Produce: Exploitation of Genotype Variation and Advancements in Analytical Protocols. AB - Horticultural commodities (fruit and vegetables) are the major dietary source of several bioactive compounds of high nutraceutical value for humans, including polyphenols, carotenoids and vitamins. The aim of the current review was dual. Firstly, toward the eventual enhancement of horticultural crops with bio functional compounds, the natural genetic variation in antioxidants found in different species and cultivars/genotypes is underlined. Notably, some landraces and/or traditional cultivars have been characterized by substantially higher phytochemical content, i.e., small tomato of Santorini island (cv. "Tomataki Santorinis") possesses appreciably high amounts of ascorbic acid (AsA). The systematic screening of key bioactive compounds in a wide range of germplasm for the identification of promising genotypes and the restoration of key gene fractions from wild species and landraces may help in reducing the loss of agro biodiversity, creating a healthier "gene pool" as the basis of future adaptation. Toward this direction, large scale comparative studies in different cultivars/genotypes of a given species provide useful insights about the ones of higher nutritional value. Secondly, the advancements in the employment of analytical techniques to determine the antioxidant potential through a convenient, easy and fast way are outlined. Such analytical techniques include electron paramagnetic resonance (EPR) and infrared (IR) spectroscopy, electrochemical, and chemometric methods, flow injection analysis (FIA), optical sensors, and high resolution screening (HRS). Taking into consideration that fruits and vegetables are complex mixtures of water- and lipid-soluble antioxidants, the exploitation of chemometrics to develop "omics" platforms (i.e., metabolomics, foodomics) is a promising tool for researchers to decode and/or predict antioxidant activity of fresh produce. For industry, the use of optical sensors and IR spectroscopy is recommended to estimate the antioxidant activity rapidly and at low cost, although legislation does not allow its correlation with health claims. PMID- 29468147 TI - Systematic Chemical Analysis Approach Reveals Superior Antioxidant Capacity via the Synergistic Effect of Flavonoid Compounds in Red Vegetative Tissues. AB - The flavonoid system comprises an abundance of compounds with multiple functions; however, their potential synergism in antioxidant function remains unclear. We established an approach using ever-red (RL) and ever-green leaves (GL) of crabapple cultivars during their development to determine interrelationships among flavonoid compounds. RL scored significantly better than GL in terms of the type, composition, and diversity of flavonoids than GL. Principal component analysis predicted flavonoids in RL to have positive interaction effects, and the total antioxidant capacity was significantly higher than the sum of antioxidant capacities of the individual compounds. This synergy was verified by the high antioxidant capacity in rat serum after feeding on red leaves. Our findings suggest that the synergistic effect is a result of the high transcription levels regulated by McMYBs in RL. In summary, individual flavonoids cooperate in a flavonoid system, thus producing a synergistic antioxidant effect, and the approach used herein can provide insights into the roles of flavonoids and other compounds in future studies. PMID- 29468149 TI - Improved Stable Isotope Dilution Assay for Dietary Folates Using LC-MS/MS and Its Application to Strawberries. AB - Folates play an important role in the human body and a deficiency of this vitamin can cause several diseases. Therefore, a reliable analytical method is crucial for the determination of folate vitamers in strawberries and other dietary folate sources. A stable isotope dilution LC-MS/MS method for analyzing folates in food was developed and validated. The folate vitamers Pteroylmonoglutamic acid, tetrahydrofolate, 5-methyltetrahydrofolate, and 5-formyltetrahydrofolate were quantified using 13C-labeled internal standards. Validation of the assay was accomplished by determining linearity, precision, recovery, limit of detection, and limit of quantification and revealed to be a precise, sensitive, and accurate method to determine folate vitamers. Strawberries are worldwide consumed and known to be a good dietary source of nutritive compounds. Using this method, folate concentrations in selected commercial strawberry cultivars and experimental breeding lines grown in Germany and Australia were investigated. Total folates varied from 59 to 153 MUg/100 g on fresh weight basis. Furthermore, folate content after lyophilizing or freezing did not show any significant differences compared to fresh strawberries. However, significant losses of total folates in pureed strawberries could be observed after 5 days of storage with only 16% of the original concentration retained. In summary, some of the investigated strawberry cultivars/breeding lines can be considered as rich dietary sources of natural folates. PMID- 29468150 TI - Editorial: Antimicrobial and Anticancer Peptides. PMID- 29468148 TI - Polyamines: Bio-Molecules with Diverse Functions in Plant and Human Health and Disease. AB - Biogenic amines-polyamines (PAs), particularly putrescine, spermidine and spermine are ubiquitous in all living cells. Their indispensable roles in many biochemical and physiological processes are becoming commonly known, including promoters of plant life and differential roles in human health and disease. PAs positively impact cellular functions in plants-exemplified by increasing longevity, reviving physiological memory, enhancing carbon and nitrogen resource allocation/signaling, as well as in plant development and responses to extreme environments. Thus, one or more PAs are commonly found in genomic and metabolomics studies using plants, particulary during different abiotic stresses. In humans, a general decline in PA levels with aging occurs parallel with some human health disorders. Also, high PA dose is detrimental to patients suffering from cancer, aging, innate immunity and cognitive impairment during Alzheimer and Parkinson diseases. A dichotomy exists in that while PAs may increase longevity and reduce some age-associated cardiovascular diseases, in disease conditions involving higher cellular proliferation, their intake has negative consequences. Thus, it is essential that PA levels be rigorously quantified in edible plant sources as well as in dietary meats. Such a database can be a guide for medical experts in order to recommend which foods/meats a patient may consume and which ones to avoid. Accordingly, designing both high and low polyamine diets for human consumption are in vogue, particularly in medical conditions where PA intake may be detrimental, for instance, cancer patients. In this review, literature data has been collated for the levels of the three main PAs, putrescine, spermidine and spermine, in different edible sources-vegetables, fruits, cereals, nuts, meat, sea food, cheese, milk, and eggs. Based on our analysis of vast literature, the effects of PAs in human/animal health fall into two broad, Yang and Yin, categories: beneficial for the physiological processes in healthy cells and detrimental under pathological conditions. PMID- 29468151 TI - Combination of Virtual Screening Protocol by in Silico toward the Discovery of Novel 4-Hydroxyphenylpyruvate Dioxygenase Inhibitors. AB - 4-Hydroxyphenylpyruvate dioxygenase (EC 1.13.11.27, HPPD) is a potent new bleaching herbicide target. Therefore, in silico structure-based virtual screening was performed in order to speed up the identification of promising HPPD inhibitors. In this study, an integrated virtual screening protocol by combining 3D-pharmacophore model, molecular docking and molecular dynamics (MD) simulation was established to find novel HPPD inhibitors from four commercial databases. 3D pharmacophore Hypo1 model was applied to efficiently narrow potential hits. The hit compounds were subsequently submitted to molecular docking studies, showing four compounds as potent inhibitor with the mechanism of the Fe(II) coordination and interaction with Phe360, Phe403, and Phe398. MD result demonstrated that nonpolar term of compound 3881 made great contributions to binding affinities. It showed an IC50 being 2.49 MUM against AtHPPD in vitro. The results provided useful information for developing novel HPPD inhibitors, leading to further understanding of the interaction mechanism of HPPD inhibitors. PMID- 29468152 TI - Negative Thermal Expansion over a Wide Temperature Range in Fe-Doped MnNiGe Composites. AB - Fe-doped MnNiGe alloys were successfully synthesized by solid-state reaction. Giant negative thermal expansion (NTE) behaviors with the coefficients of thermal expansion (CTE) of -285.23 * 10-6 K-1 (192-305 K) and -1167.09 * 10-6 K-1 (246 305 K) have been obtained in Mn0.90Fe0.10NiGe and MnNi0.90Fe0.10Ge, respectively. Furthermore, these materials were combined with Cu in order to control the NTE properties. The results indicate that the absolute value of CTE gradually decreases with increasing Cu contents. In Mn0.92Fe0.08NiGe/x%Cu, the CTE gradually changes from -64.92 * 10-6 K-1 (125-274 K) to -4.73 * 10-6 K-1 (173-229 K) with increasing value of x from 15 to 70. The magnetic measurements reveal that the NTE behaviors in this work are strongly correlated with the process of the magnetic phase transition and the introduction of Fe atoms could also change the spiral anti-ferromagnetic (s-AFM) state into ferromagnetic (FM) state at low temperature. Our study launches a new candidate for controlling thermal expansion properties of metal matrix materials which could have potential application in variable temperature environment. PMID- 29468153 TI - The Correlation of Adsorption Behavior between Ciprofloxacin Hydrochloride and the Active Sites of Fe-doped MCM-41. AB - HIGHLIGHTS Fe incorporation significantly accelerated the adsorption of CPX on MCM-41.Fe leaching can be ignored when pH was higher than 4.0.pH played an important role in CPX adsorption on Fe-MCM-41.Co-effect of CPX and metal cations on Fe-MCM-41 was investigated. Fe-MCM-41s with various molar ratios of silicon to iron (20, 40, 80, and 160) were prepared to investigate adsorption properties of ciprofloxacin hydrochloride (CPX) in aqueous solutions. Fe-MCM-41s were characterized by transmission electron microscope (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), nitrogen adsorption/desorption isotherms, and infrared spectroscopy (FT-IR). Effects of silicon-iron ratio, adsorbent dosage, pH, and temperature were conducted to explore the adsorption mechanism of CPX on Fe-MCM-41. The results showed that the introduction of iron facilitated the absorption quantity for CPX from 20.04 to 83.33 mg g-1 at 120 min of reaction time, which was mainly attributed to surface complexation. The promotion of hydrophobic effect, electrostatic interactions, and pi-pi electron donor-acceptor interaction also played coordinate roles in the adsorption process. The experimental kinetic data followed both the pseudo-second-order and intra particle diffusion models, while the adsorption isotherm data fit well to Freundlich model at high temperature. Thermodynamic study showed that the adsorption was spontaneous. Under the effect of electrostatic interaction, pH of the solution strongly affected CPX adsorption. Five representative metal cations (Ca, Cu, Ni, Pb, and Cd) were chosen to study the effects on CPX adsorption and their complexation. The inhibiting effect of metal cations on CPX adsorption was sequenced in the order of Cu > Ni > Pb > Cd > Ca, which followed the same order as the complexation stability constants between CPX and cations. The Fe-MCM-41 adsorbent possessed excellent reusability for 4 cycles use, suggesting a potential applicability of Fe-MCM-41 to remove CPX in water. PMID- 29468154 TI - Synthesis of Samarium-Cobalt Sub-micron Fibers and Their Excellent Hard Magnetic Properties. AB - High-throughput synthesis of Samarium-Cobalt sub-micron fibers with controlled composition and dimension was demonstrated by combining electrospinning and reduction-diffusion processes. The composition of fibers was readily varied (8 < Sm < 20 at.%) by adjusting precursor composition whereas the diameter of fibers was precisely controlled by varying electrospinning parameters (e.g., applied voltage, solution feed rate, temperature, and humidity) to reach single-domain size. X-ray diffraction patterns confirmed that single phase Sm2Co17 fibers were synthesized when the metal precursor ratio (Sm3+/(Sm3++Co2+)) was precisely controlled at 10.6%, whereas mixed phases (i.e., Co-Sm2Co17 or Sm2Co17-Sm2Co7) were observed when the ratio is deviated from the stoichiometric. Magnetic saturation (Ms ) of the synthesized fibers monotonically decreased with an increased in Sm content. In contrast, coercivity (Hci) monotonically increased with an increase in Sm content. PMID- 29468155 TI - A Low Cost Implantation Model in the Rat That Allows a Spatial Assessment of Angiogenesis. AB - There is continual demand for animal models that allow a quantitative assessment of angiogenic properties of biomaterials, therapies, and pharmaceuticals. In its simplest form, this is done by subcutaneous material implantation and subsequent vessel counting which usually omits spatial data. We have refined an implantation model and paired it with a computational analytic routine which outputs not only vessel count but also vessel density, distribution, and vessel penetration depth, that relies on a centric vessel as a reference point. We have successfully validated our model by characterizing the angiogenic potential of a fibrin matrix in conjunction with recombinant human vascular endothelial growth factor (rhVEGF165). The inferior epigastric vascular pedicles of rats were sheathed with silicone tubes, which were subsequently filled with 0.2 ml of fibrin and different doses of rhVEGF165, centrically embedding the vessels. Over 4 weeks, tissue samples were harvested and subsequently immunohistologically stained and computationally analyzed. The model was able to detect variations over the angiogenic potentials of growth factor spiked fibrin matrices. Adding 20 ng of rhVEGF165 resulted in a significant increase in vasculature while 200 ng of rhVEGF165 did not improve vascular growth. Vascularized tissue volume increased during the first week and vascular density increased during the second week. Total vessel count increased significantly and exhibited a peak after 2 weeks which was followed by a resorption of vasculature by week 4. In summary, a simple implantation model to study in vivo vascularization with only a minimal workload attached was enhanced to include morphologic data of the emerging vascular tree. PMID- 29468156 TI - Adherent vs. Free-Floating Neural Induction by Dual SMAD Inhibition for Neurosphere Cultures Derived from Human Induced Pluripotent Stem Cells. AB - Keeping neural stem cells under proliferation, followed by terminal differentiation, can substantially increase the number of neurons generated. With regard to the usability of proliferating neurospheres (NSPHs) cultures, adherent induction protocols have not yet been studied in comparison to embryoid body (EB) based protocols. To compare these proctocols, neural induction of human induced pluripotent stem cells was performed by dual SMAD inhibition under both adherent and free-floating EB culture conditions. After 10 days, we transferred cells to low-attachment culture plates and proliferated them as free-floating neurospheres. RNA was collected, transcribed to cDNA and analyzed for sonic hedgehog expression that plays an important role during proliferation process. NSPHs were analyzed by immunofluorescence imaging directly and upon continued differentiation. The EB-based approach yielded in higher numbers of cells expressing the neural stem cell marker Nestin, and showed in contrast to the adherent induction protocol increased expression levels of sonic hedgehog. Although improvements to culture consistency and reliability are desirable, the EB-based protocol appears to be superior to the adherent protocol for both, the proliferation and differentiation capacity. PMID- 29468157 TI - Dancing Styles of Collective Cell Migration: Image-Based Computational Analysis of JRAB/MICAL-L2. AB - Collective cell migration is observed during morphogenesis, angiogenesis, and wound healing, and this type of cell migration also contributes to efficient metastasis in some kinds of cancers. Because collectively migrating cells are much better organized than a random assemblage of individual cells, there seems to be a kind of order in migrating clusters. Extensive research has identified a large number of molecules involved in collective cell migration, and these factors have been analyzed using dramatic advances in imaging technology. To date, however, it remains unclear how myriad cells are integrated as a single unit. Recently, we observed unbalanced collective cell migrations that can be likened to either precision dancing or awa-odori, Japanese traditional dancing similar to the style at Rio Carnival, caused by the impairment of the conformational change of JRAB/MICAL-L2. This review begins with a brief history of image-based computational analyses on cell migration, explains why quantitative analysis of the stylization of collective cell behavior is difficult, and finally introduces our recent work on JRAB/MICAL-L2 as a successful example of the multidisciplinary approach combining cell biology, live imaging, and computational biology. In combination, these methods have enabled quantitative evaluations of the "dancing style" of collective cell migration. PMID- 29468158 TI - Central and Peripheral Nervous System Progenitors Derived from Human Pluripotent Stem Cells Reveal a Unique Temporal and Cell-Type Specific Expression of PMCAs. AB - The P-type ATPases family consists of ion and lipid transporters. Their unique diversity in function and expression is critical for normal development. In this study we investigated human pluripotent stem cells (hPSC) and different neural progenitor states to characterize the expression of the plasma membrane calcium ATPases (PMCAs) during human neural development and in mature mesencephalic dopaminergic (mesDA) neurons. Our RNA sequencing data identified a dynamic change in ATPase expression correlating with the differentiation time of the neural progenitors, which was independent of the neuronal progenitor type. Expression of ATP2B1 and ATP2B4 were the most abundantly expressed, in accordance with their main role in Ca2+ regulation and we observed all of the PMCAs to have a subcellular punctate localization. Interestingly in hPSCs ATP2B1 and ATP2B3 were highly expressed in a cell cycle specific manner and ATP2B2 and ATP2B4 were highly expressed in a hPSC sub-population. In neural rosettes a strong apical PMCA expression was identified in the luminal region. Lastly, we confirmed all PMCAs to be expressed in mesDA neurons, however at varying levels. Our results reveal that PMCA expression dynamically changes during stem cell differentiation and highlights the diverging needs of cell populations to regulate and properly integrate Ca2+ changes, which can ultimately correspond to changes in specific stem cell transcription states. PMID- 29468159 TI - IL-1beta Promotes a New Function of DNase I as a Transcription Factor for the Fas Receptor Gene. AB - Recently we described that endonuclease inactive DNase I translocated into the nucleus in response to increased endogenous IL-1beta expression. Here, we demonstrate impact and function of translocated DNase I in tubular cells. Effect of cytokines on expression level and nuclear localisation of DNase I and corresponding levels of Fas receptor (FasR) and IL-1beta were determined by confocal microscopy, qPCR and western blot analyses, in presence or absence of siRNA against IL-1beta and DNase I mRNA. Nuclear DNase I bound to the FAS promotor region as determined by chromatin immuno-precipitation analysis. Data demonstrate that; (i) translocation of DNase I depended on endogenous de novo expressed IL-1beta, (ii) nuclear DNase I bound FAS DNA, (iii) FasR expression increased after translocation of DNase I, (iv) interaction of exogenous Fas ligand (FasL) with upregulated FasR induced apoptosis in human tubular cells stimulated with TNFalpha. Thus, translocated DNase I most probably binds the promoter region of the FAS gene and function as a transcription factor for FasR. In conclusion, DNase I not only executes chromatin degradation during apoptosis and necrosis, but also primes the cells for apoptosis by enhancing FasR expression. PMID- 29468161 TI - Big Data and Dementia: Charting the Route Ahead for Research, Ethics, and Policy. AB - Emerging trends in pervasive computing and medical informatics are creating the possibility for large-scale collection, sharing, aggregation and analysis of unprecedented volumes of data, a phenomenon commonly known as big data. In this contribution, we review the existing scientific literature on big data approaches to dementia, as well as commercially available mobile-based applications in this domain. Our analysis suggests that big data approaches to dementia research and care hold promise for improving current preventive and predictive models, casting light on the etiology of the disease, enabling earlier diagnosis, optimizing resource allocation, and delivering more tailored treatments to patients with specific disease trajectories. Such promissory outlook, however, has not materialized yet, and raises a number of technical, scientific, ethical, and regulatory challenges. This paper provides an assessment of these challenges and charts the route ahead for research, ethics, and policy. PMID- 29468160 TI - Adhesion GPCRs in Kidney Development and Disease. AB - Chronic kidney disease (CKD) represents the fastest growing pathology worldwide with a prevalence of >10% in many countries. In addition, kidney cancer represents 5% of all new diagnosed cancers. As currently no effective therapies exist to restore kidney function after CKD- as well as cancer-induced renal damage, it is important to elucidate new regulators of kidney development and disease as new therapeutic targets. G protein-coupled receptors (GPCRs) represent the most successful class of pharmaceutical targets. In recent years adhesion GPCRs (aGPCRs), the second largest GPCR family, gained significant attention as they are present on almost all mammalian cells, are associated to a plethora of diseases and regulate important cellular processes. aGPCRs regulate for example cell polarity, mitotic spindle orientation, cell migration, and cell aggregation; all processes that play important roles in kidney development and/or disease. Moreover, polycystin-1, a major regulator of kidney development and disease, contains a GAIN domain, which is otherwise only found in aGPCRs. In this review, we assess the potential of aGPCRs as therapeutic targets for kidney disease. For this purpose we have summarized the available literature and analyzed data from the databases The Human Protein Atlas, EURExpress, Nephroseq, FireBrowse, cBioPortal for Cancer Genomics and the National Cancer Institute Genomic Data Commons data portal (NCIGDC). Our data indicate that most aGPCRs are expressed in different spatio-temporal patterns during kidney development and that altered aGPCR expression is associated with a variety of kidney diseases including CKD, diabetic nephropathy, lupus nephritis as well as renal cell carcinoma. We conclude that aGPCRs present a promising new class of therapeutic targets and/or might be useful as diagnostic markers in kidney disease. PMID- 29468162 TI - Short-term Oral Antibiotics Treatment Promotes Inflammatory Activation of Colonic Invariant Natural Killer T and Conventional CD4+ T Cells. AB - The gut mucosa is continuously exposed to a vast community of microorganisms, collectively defined as microbiota, establishing a mutualistic relationship with the host and contributing to shape the immune system. Gut microbiota is acquired at birth, and its composition is relatively stable during the entire adult life. Intestinal dysbiosis, defined as a microbial imbalance of gut bacterial communities, can be caused by several factors, including bacterial infections and antibiotic use, and has been associated with an increased risk to develop or exacerbate immune-mediated pathologies, such as allergic reactions, asthma, and inflammatory bowel diseases. Still, the mechanisms by which antibiotic-induced gut dysbiosis may lead to development of mucosal inflammation are still matter of debate. To this end, we aimed to evaluate the impact of antibiotic treatment on phenotype and functions of intestinal immune cell populations, including invariant natural killer T (iNKT) cells, a subset of lipid-specific T cells profoundly influenced by alterations on the commensal microbiota. To this aim, a cocktail of broad-spectrum antibiotics was administered for 2 weeks to otherwise healthy mice before re-colonization of the intestinal microbial community with oral gavage of eubiotic or dysbiotic mucosa-associated bacteria and luminal colonic content, followed or not by intestinal inflammation induction. Here. we showed that short-term antibiotic treatment alters frequency and functions of intestinal iNKT cells, even in the absence of intestinal inflammation. The presence of a dysbiotic microbiota after antibiotic treatment imprints colonic iNKT and CD4+ T cells toward a pro-inflammatory phenotype that collectively contributes to aggravate intestinal inflammation. Nonetheless, the inflammatory potential of the dysbiotic microbiota decreases over time opening the possibility to temporally intervene on the microbial composition to re-equilibrate dysbiosis, thus controlling concomitantly mucosal immune T cell activations. PMID- 29468163 TI - The Effect of Flaxseed in Breast Cancer: A Literature Review. AB - Breast cancer is one of the most common cancers and the second most responsible for cancer mortality worldwide. In 2014, in Portugal approximately 27,200 people died of cancer, of which 1,791 were women with breast cancer. Flaxseed has been one of the most studied foods, regarding possible relations to breast cancer, though mainly in experimental studies in animals, yet in few clinical trials. It is rich in omega-3 fatty acids, alpha-linolenic acid, lignan, and fibers. One of the main components of flaxseed is the lignans, of which 95% are made of the predominant secoisolariciresinol diglucoside (SDG). SDG is converted into enterolactone and enterodiol, both with antiestrogen activity and structurally similar to estrogen; they can bind to cell receptors, decreasing cell growth. Some studies have shown that the intake of omega-3 fatty acids is related to the reduction of breast cancer risk. In animal studies, alpha-linolenic acids have been shown to be able to suppress growth, size, and proliferation of cancer cells and also to promote breast cancer cell death. Other animal studies found that the intake of flaxseed combined with tamoxifen can reduce tumor size to a greater extent than taking tamoxifen alone. Additionally, some clinical trials showed that flaxseed can have an important role in decreasing breast cancer risk, mainly in postmenopausal women. Further studies are needed, specifically clinical trials that may demonstrate the potential benefits of flaxseed in breast cancer. PMID- 29468164 TI - Glutamine Hydrolysis by Imidazole Glycerol Phosphate Synthase Displays Temperature Dependent Allosteric Activation. AB - The enzyme imidazole glycerol phosphate synthase (IGPS) is a model for studies of long-range allosteric regulation in enzymes. Binding of the allosteric effector ligand N'-[5'-phosphoribulosyl)formimino]-5-aminoimidazole-4-carboxamide ribonucleotide (PRFAR) stimulates millisecond (ms) timescale motions in IGPS that enhance its catalytic function. We studied the effect of temperature on these critical conformational motions and the catalytic mechanism of IGPS from the hyperthermophile Thermatoga maritima in an effort to understand temperature dependent allostery. Enzyme kinetic and NMR dynamics measurements show that apo and PRFAR-activated IGPS respond differently to changes in temperature. Multiple quantum Carr-Purcell-Meiboom-Gill (CPMG) relaxation dispersion experiments performed at 303, 323, and 343 K (30, 50, and 70 degrees C) reveal that millisecond flexibility is enhanced to a higher degree in apo IGPS than in the PRFAR-bound enzyme as the sample temperature is raised. We find that the flexibility of the apo enzyme is nearly identical to that of its PRFAR activated state at 343 K, whereas conformational motions are considerably different between these two forms of the enzyme at room temperature. Arrhenius analyses of these flexible sites show a varied range of activation energies that loosely correlate to allosteric communities identified by computational methods and reflect local changes in dynamics that may facilitate conformational sampling of the active conformation. In addition, kinetic assays indicate that allosteric activation by PRFAR decreases to 65-fold at 343 K, compared to 4,200-fold at 303 K, which mirrors the decreased effect of PRFAR on ms motions relative to the unactivated enzyme. These studies indicate that at the growth temperature of T. maritima, PFRAR is a weaker allosteric activator than it is at room temperature and illustrate that the allosteric mechanism of IGPS is temperature dependent. PMID- 29468165 TI - A Review of African Swine Fever and the Potential for Introduction into the United States and the Possibility of Subsequent Establishment in Feral Swine and Native Ticks. AB - African swine fever (ASF) is caused by African swine fever virus (ASFV), which can cause substantial morbidity and mortality events in swine. The virus can be transmitted via direct and indirect contacts with infected swine, their products, or competent vector species, especially Ornithodoros ticks. Africa and much of Eastern Europe are endemic for ASF; a viral introduction to countries that are currently ASF free could have severe economic consequences due to the loss of production from infected animals and the trade restrictions that would likely be imposed as a result of an outbreak. We identified vulnerabilities that could lead to ASFV introduction or persistence in the United States or other ASF-free regions. Both legal and illegal movements of live animals, as well as the importation of animal products, byproducts, and animal feed, pose a risk of virus introduction. Each route is described, and current regulations designed to prevent ASFV and other pathogens from entering the United States are outlined. Furthermore, existing ASFV research gaps are highlighted. Laboratory experiments to evaluate multiple species of Ornithodoros ticks that have yet to be characterized would be useful to understand vector competence, host preferences, and distribution of competent soft tick vectors in relation to high pig production areas as well as regions with high feral swine (wild boar or similar) densities. Knowledge relative to antigenic viral proteins that contribute to host response and determination of immune mechanisms that lead to protection are foundational in the quest for a vaccine. Finally, sampling of illegally imported and confiscated wild suid products for ASFV could shed light on the types of products being imported and provide a more informed perspective relative to the risk of ASFV importation. PMID- 29468166 TI - Suspicion of Postanesthetic Femoral Paralysis of the Non-Dependent Limb in a Horse. AB - A 15-year-old Selle Francais gelding was presented to the equine referral hospital for treatment of a left guttural pouch mycosis previously diagnosed. After induction, the horse was shortly hoisted by all four feet, moved on a padded surgical table, and positioned in right lateral recumbency. In order to reduce the risk of bleeding during surgical manipulation of the carotid and maxillary arteries, a mean arterial pressure between 60 and 70 mmHg was targeted. After surgery, the horse was moved in a padded recovery box keeping the same lateral recumbency. Four unsuccessful attempts were performed, with the horse always returning to sternal recumbency keeping the left hind limb up. At the fifth attempt, performed 120 min after the end of the general anesthesia, the horse stood up correctly but moderate ataxia and absence of weight bearing on the left hind limb were shown. Both the stifle and the fetlock joint were held in a flexed position and could not be extended properly in order to set the foot on the ground, resulting in a very short step. The horse was calm, not sweating, and willing to move; the muscles of the affected limb were relaxed, and the limb was neither warm nor painful at palpation. Occasionally, the horse flexed the affected hind limb in an exaggerated motion with marked abduction. No additional laboratory analyses were performed. Due to a strong suspicion of neuropathy, a sling support was initiated and a supportive bandage associated with flunixine administration was performed until resolution of the symptoms. The horse fully recovered after 3 days. This case report does not clarify the pathogenesis of the possible postanesthetic neuropathy accounted on the non-dependent limb, highlighting the need for future research in this field. Non-dependent limb neuropathy should be an expected problem even after having ruled out the most commonly known causes predisposing to postanesthetic lameness. PMID- 29468167 TI - Fatal fulminant herpes simplex hepatitis following surgery in an adult. AB - We present a case of a healthy 72-year-old man with herpes simplex hepatitis (HSVH) development soon after ordinary surgery for biliary stones. A sudden onset of hepatitis associated with high fever and leukopenia emerged on postoperative day 5, followed by a rapid and lethal course (died on day 9), despite an acyclovir therapy on day 8. Postmortem liver biopsy revealed positive immunostaining for herpes simplex virus (HSV) type-1. The serum tests (available after the death) were negative for anti-HSV immunogloblulins, but positive for HSV DNA. A review of 15 cases of postsurgical HSVH along with 42 cases of non surgical HSH showed that (1): A wide spectrum of surgical procedures was involved; and (2): High mortality (87%) associated with lower rates of ante mortem diagnosis (20%) and acyclovir treatment (20%). Due to the difficulty in diagnosis and lethal nature, an early clinical suspension and prompt empirical anti-viral intervention are imperative for postsurgical hepatitis with undetermined etiology, characterized by fever and leucopenia. PMID- 29468168 TI - Severe Pulmonary Hypertension Due to Adult-Onset Still's Disease. AB - A 29-year-old female with adult-onset Still's disease (AOSD) presented with progressive shortness of breath both on rest and on exertion, increased abdominal girth, and swelling in both legs. She was on oral prednisone and was recently started on canakinumab (interleukin-1 antagonist) for joint pain and rash of AOSD. Echocardiogram showed severely dilated right ventricle, dilated pulmonary artery, moderately reduced right ventricular systolic function, but with normal left ventricular systolic function. Computed tomography with contrast ruled out pulmonary embolism. Blood tests ruled out other rheumatologic diseases. The patient was diagnosed with right-sided heart failure likely secondary to AOSD. Right heart catheterization was needed but could not be performed because of severely dilated pulmonary artery. The patient was transferred to a higher center for further management and possible cardiopulmonary transplant. PMID- 29468169 TI - Severe Human Granulocytic Anaplasmosis With Significantly Elevated Ferritin Levels in an Immunocompetent Host in Pennsylvania: A Case Report. AB - Human granulocytic anaplasmosis (HGA) is a tick-borne, infectious disease caused by Anaplasma phagocytophilum that generally presents with nonspecific symptoms such as fever, chills, headache, malaise, and myalgia. If not treated immediately, HGA can cause hemophagocytic lymphohistiocytosis (HLH), a well documented but underrecognized sequela of severe HGA. In this article, we report a case of severe HGA with hyperferritinemia in a 74-year-old male from Central Pennsylvania who initially presented with recurrent fevers, nausea, and malaise to our emergency department and was subsequently discharged home that same day. Ten days later, the patient returned with acute kidney injury, elevated liver transaminases, and profound hyperferritinemia to 5130 ng/mL. Empiric doxycycline was administered for suspected tick-borne disease and serologies eventually came back positive for anti-Anaplasma phagocytophilum antibodies. The patient returned to baseline status 15 days after discharge. Our case shows the challenges in the timely diagnosis of HGA and highlights the role of serum ferritin in aiding this diagnosis. Although our patient did not fulfill the HLH diagnostic criteria, our report demonstrates the importance of recognizing HGA as a reversible cause of HLH.

PMID- 29468171 TI - Influence of Meniscal and Chondral Lesions on Patient-Reported Outcomes After Primary Anterior Cruciate Ligament Reconstruction at 2-Year Follow-up. AB - Background: Meniscal and chondral lesions are commonly associated with anterior cruciate ligament (ACL) tears, and these lesions may play a role in patient outcomes after ACL reconstruction. Purpose: To determine the effects of the presence and location of meniscal and chondral lesions at the time of ACL reconstruction on patient-reported outcomes at a minimum 2-year follow-up. Study Design: Cohort study; Level of evidence, 3. Methods: Patients with no prior knee surgery who underwent primary ACL reconstruction by a single surgeon between 2010 and 2014 were included in this study. Those meeting inclusion criteria were divided into the following groups based on the arthroscopic diagnosis: patients without concomitant meniscal or chondral lesions, patients with isolated meniscal lesions, patients with isolated chondral lesions, and patients with both chondral and meniscal lesions. Patient-reported outcomes (Short Form-12 [SF-12] physical component summary [PCS] and mental component summary [MCS], Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC], and Lysholm scale) were assessed at a minimum of 2 years from the index surgery. Results: A total of 151 patients met the inclusion criteria and were included in the study. The mean age at the time of surgery was 36.2 years (range, 14-73 years), and the mean follow up was 3.2 years (range, 2.0-5.6 years). At the time of surgery, 33 (22%) patients had no concomitant lesions and served as the control group, 63 (42%) patients had isolated meniscal lesions, 21 (14%) patients had isolated chondral lesions, and 34 (22%) patients had both chondral and meniscal lesions. There was significant improvement in all outcome scores postoperatively for the 3 groups (P < .05 for all outcome scores). The presence of a meniscal tear and laterality of the meniscal lesion did not have a negative effect on any postoperative outcome scores. Patients with isolated chondral lesions had significantly lower postoperative WOMAC scores compared with patients without chondral lesions (P < .05). No significant differences were found for all other scores. Patients with patellofemoral chondral lesions had significantly lower postoperative SF-12 PCS and Lysholm scores than patients with tibiofemoral chondral lesions (P < .05). Conclusion: Patients with ACL tears achieved improved functional scores at a mean 3.2 years after ACL reconstruction. While meniscal lesions did not affect postoperative outcomes in the short term, chondral lesions were identified as a predictor for worse outcomes. PMID- 29468172 TI - Hip Arthroscopic Surgery for Femoroacetabular Impingement: A Prospective Analysis of the Relationship Between Surgeon Experience and Patient Outcomes. AB - Background: Hip arthroscopic surgery is a rapidly growing procedure, but it may be associated with a steep learning curve. Few studies have used patient-reported outcome (PRO) surveys to investigate the relationship between surgeon experience and patient outcomes after the arthroscopic treatment of femoroacetabular impingement (FAI). Hypothesis: Patients undergoing hip arthroscopic surgery for the treatment of FAI in the early stages of a surgeon's career will have significantly worse outcomes and longer procedure times compared with patients treated after the surgeon has gained experience. Study Design: Cohort study; Level of evidence, 2. Methods: Patients undergoing hip arthroscopic surgery for FAI and labral injuries were prospectively enrolled during a sports medicine fellowship-trained surgeon's first 15 months of practice. Patients were stratified into an early group, consisting of the first 30 consecutive cases performed by the surgeon, and a late group, consisting of the second 30 consecutive cases. Radiographic and physical examinations were performed preoperatively and postoperatively. PRO surveys, including the 12-item Short Form Health Survey (SF-12), the modified Harris Hip Score (mHHS), and the Hip disability and Osteoarthritis Outcome Score (HOOS), were administered preoperatively and at a minimum of 1 year postoperatively. Results: There was no difference between the early and late groups for patient age (37.2 +/- 11.5 vs 35.3 +/- 10.8 years, respectively; P = .489), body mass index (25.6 +/- 4.0 vs 25.1 +/- 4.5 kg/m2, respectively; P = .615), or sex (P = .465). There was a significantly increased procedure time (119.3 +/- 21.0 vs 99.0 +/- 28.6 minutes, respectively; P = .002) and traction time (72.7 +/- 21.4 vs 59.0 +/- 16.7 minutes, respectively; P = .007) in the early group compared with the late group. Mean postoperative PRO scores significantly improved in both groups compared with preoperative values for all surveys except for the SF-12 mental component summary. No differences were found in PRO score improvements or complication rates between the early and late groups. Conclusion: The total procedure time and traction time decrease after a surgeon's first 30 hip arthroscopic surgery cases for FAI and labral tears, but patient outcomes can similarly improve regardless of surgeon experience in the early part of his or her career. PMID- 29468173 TI - Effect of desipramine on patients with breathing disorders in RETT syndrome. AB - Objective: Rett Syndrome (RTT) is a severe neurodevelopmental condition with breathing disorders, affecting around one in 10,000 female births. Desipramine, a noradrenaline reuptake inhibitor, reduced the number of apneas in Mecp2-deficient mice, a model of RTT. We planned a phase 2 trial to test its efficacy and its safety on breathing patterns in 36 girls with RTT. Methods: The trial was a 6 month, multicenter, randomized, double-blind, placebo-controlled study registered with ClinicalTrials.gov, number NCT00990691. Girls diagnosed according to clinical examination and confirmed by genotyping were randomly assigned in a 1:1:1 ratio to receive 2-3 mg/kg Desipramine per day (high Desipramine), 1-2 mg/kg Desipramine per day (low Desipramine), or a placebo. The primary outcome was the change of apnea hypopnea index (AHI), defined by the number of apnea and hypopnea events per hour, assessed at 6 months from baseline. Intention-to-treat analysis was applied. Results: The median change in AHI from baseline to 6 months was -31 (IQR: -37 to -11) for the high Desipramine, -17.5 (IQR: -31 to 13) for the low Desipramine, and -13 (IQR:-31 to 0) for the placebo group. We did not find any significant difference in these changes between the groups (P = 0.781). A significant inverse correlation between Desipramine plasma concentration and AHI (r = -0.44; P = 0.0002) was underlined. Interpretation: This first clinical trial of desipramine did not show clinical efficacy. Although required further studies, the significant correlation between Desipramine concentrations and improvement of AHI provided additional and relevant reasons to test the noradrenergic pathway in RTT. PMID- 29468174 TI - Brain atrophy measures in preclinical and manifest spinocerebellar ataxia type 2. AB - Objective: Spinocerebellar ataxia type 2 (SCA2) is an autosomal dominantly inherited neurodegenerative disease mainly affecting the cerebellum and brainstem. In this Cuban-German research collaboration, we aimed to characterize atrophy patterns and associations with clinical measures in preclinical and manifest SCA2. Methods: In this study, 16 nonmanifest SCA2 mutation carriers, 26 manifest patients with SCA2, and 18 healthy control subjects underwent magnetic resonance imaging, as well as genetic and clinical characterization including assessment of ataxia (Scale for the Assessment and Rating of Ataxia) and saccade velocity in Cuba were enrolled. Semiautomated quantitative volumetry of the cerebellum and brainstem, subdivided into the medulla oblongata, the pontine brainstem, and mesencephalon was performed. Additionally, the anteroposterior diameter of the pontine brainstem was measured. Results: Analysis of volumetric data revealed degeneration of the cerebellum and brainstem, in particular of pontine volumes and the anteroposterior diameter of the pons, in both manifest SCA2 patients and individuals at risk for SCA2 compared to controls. Comparing patients with nonataxic preclinical SCA2 mutation carriers, we found more pronounced reductions of the pontine brainstem and cerebellum in manifest SCA2. Volumetric data further showed associations with CAG repeat length and predicted age of onset in preclinical SCA2 individuals, and by trend with ataxia signs in patients. Although saccade velocity was associated with reduction in the pontine brainstem in preclinical and manifest SCA2, reduced ability to suppress interfering stimuli measured by the Stroop task was related to cerebellar volume loss in patients. Interpretation: Preclinical SCA2 mutation carriers exhibit brain abnormalities, which could be targeted as surrogate parameters for disease progression and in future preventive trials. PMID- 29468175 TI - Rapamycin prevents cerebral stroke by modulating apoptosis and autophagy in penumbra in rats. AB - Objective: Whether activation or inhibition of the mTOR pathway is beneficial to ischemic injury remains controversial. It may result from the different reaction of ischemic penumbra and core to modulation of mTOR pathway after cerebral ischemia-reperfusion injury in rats. Methods: Longa's middle cerebral artery occlusion (MCAO) method was conducted to induce the focal cerebral ischemia reperfusion. Western blot analysis was used to examine the protein expression involving mTOR pathway, apoptosis, and autophagy-related proteins. TTC staining and Fluoro-Jade B staining was conducted to detect the infarct volume and cell apoptosis, respectively. Neurological function was measured by modified neurological severity score and left-biased swing. Results: mTOR signaling pathway was activated in ischemic penumbra and decreased in ischemic core after ischemia and ischemia-reperfusion. Ischemia-reperfusion injury induced the increase in cleaved caspase 9 and caspase 3 both in ischemic penumbra and in ischemic core, whereas the expression of phosphorylated ULK1, Beclin 1 and LC3-II was decreased. Rapamycin pre or postadministration inhibited the overactivation of mTOR pathway in ischemic penumbra. Ameliorated neurological function and reduced infarct volume were observed after pre or postrapamycin treatment. Rapamycin markedly decreased the number of FJB-positive cells and the expression of cleaved caspase-3 and cleaved caspase-9 proteins as well as increased the activation of autophagy reflected by ULK1, Beclin-1 and LC3. Interpretation: mTOR signaling pathway was activated in ischemic penumbra after cerebral ischemia reperfusion injury in rats. mTOR inhibitor rapamycin significantly decreased the mTOR activation and infarct volume and subsequently improved neurological function. These results may relate to inhibition of neuron apoptosis and activation of autophagy. PMID- 29468176 TI - Inhibition of the potassium channel Kv1.3 reduces infarction and inflammation in ischemic stroke. AB - Objective: Inhibitors of the voltage-gated K+ channel Kv1.3 are currently in development as immunomodulators for the treatment of autoimmune diseases. As Kv1.3 is also expressed on microglia and has been shown to be specifically up regulated on "M1-like" microglia, we here tested the therapeutic hypothesis that the brain-penetrant small-molecule Kv1.3-inhibitor PAP-1 reduces secondary inflammatory damage after ischemia/reperfusion. Methods: We studied microglial Kv1.3 expression using electrophysiology and immunohistochemistry, and evaluated PAP-1 in hypoxia-exposed organotypic hippocampal slices and in middle cerebral artery occlusion (MCAO) with 8 days of reperfusion in both adult male C57BL/6J mice (60 min MCAO) and adult male Wistar rats (90 min MCAO). In both models, PAP 1 administration was started 12 h after reperfusion. Results: We observed Kv1.3 staining on activated microglia in ischemic infarcts in mice, rats, and humans and found higher Kv1.3 current densities in acutely isolated microglia from the infarcted hemisphere than in microglia isolated from the contralateral hemisphere of MCAO mice. PAP-1 reduced microglia activation and increased neuronal survival in hypoxia-exposed hippocampal slices as effectively as minocycline. In mouse MCAO, PAP-1 dose-dependently reduced infarct area, improved neurological deficit score, and reduced brain levels of IL-1beta and IFN-gamma without affecting IL-10 and brain-derived nerve growth factor (BDNF) levels or inhibiting ongoing phagocytosis. The beneficial effects on infarct area and neurological deficit score were reproduced in rats providing confirmation in a second species. Interpretation: Our findings suggest that Kv1.3 constitutes a promising therapeutic target for preferentially inhibiting "M1-like" inflammatory microglia/macrophage functions in ischemic stroke. PMID- 29468177 TI - CSF neurogranin or tau distinguish typical and atypical Alzheimer disease. AB - Objective: To assess whether high levels of cerebrospinal fluid neurogranin are found in atypical as well as typical Alzheimer's disease. Methods: Immunoassays were used to measure cerebrospinal fluid neurogranin in 114 participants including healthy controls (n = 27), biomarker-proven amnestic Alzheimer's disease (n = 68), and the atypical visual variant of Alzheimer's (n = 19) according to international criteria. CSF total-tau, Abeta42, and neurofilament light concentrations were investigated using commercially available assays. All affected individuals had T1-weighted volumetric MR images available for analysis of whole and regional brain volumes. Associations between neurogranin, brain volumes, total-tau, Abeta42, and neurofilament light were assessed. Results: Median cerebrospinal fluid neurogranin concentrations were higher in typical and atypical Alzheimer's compared to controls (P < 0.001 and P = 0.005). Both neurogranin and total-tau concentrations, but not neurofilament light and Abeta42, were higher in typical Alzheimer's compared to atypical patients (P = 0.004 and P = 0.03). There were significant differences in the left hippocampus and right and left superior parietal lobules in atypical patients, which were larger (P = 0.03) and smaller (P = 0.001 and P < 0.001), respectively, compared to typical patients. We found no evidence of associations between neurogranin and brain volumes but a strong association with total-tau (P < 0.001) and a weaker association with neurofilament light (P = 0.005). Interpretation: These results show significant differences in neurogranin and total-tau between typical and atypical patients, which may relate to factors other than disease topography. The differential relationships between neurogranin, total-tau and neurofilament light in the Alzheimer's variants, provide evidence for mechanistically distinct and coupled markers of neurodegeneration. PMID- 29468178 TI - Retrograde interferon-gamma signaling induces major histocompatibility class I expression in human-induced pluripotent stem cell-derived neurons. AB - Objective: Injury-associated axon-intrinsic signals are thought to underlie pathogenesis and progression in many neuroinflammatory and neurodegenerative diseases, including multiple sclerosis (MS). Retrograde interferon gamma (IFN gamma) signals are known to induce expression of major histocompatibility class I (MHC I) genes in murine axons, thereby increasing the susceptibility of these axons to attack by antigen-specific CD8+ T cells. We sought to determine whether the same is true in human neurons. Methods: A novel microisolation chamber design was used to physically isolate and manipulate axons from human skin fibroblast derived induced pluripotent stem cell (iPSC)-derived neuron-enriched neural aggregates. Fluorescent retrobeads were used to assess the fraction of neurons with projections to the distal chamber. Axons were treated with IFN gamma for 72 h and expression of MHC class I and antigen presentation genes were evaluated by RT-PCR and immunofluorescence. Results: Human iPSC-derived neural stem cells maintained as 3D aggregate cultures in the cell body chamber of polymer microisolation chambers extended dense axonal projections into the fluidically isolated distal chamber. Treatment of these axons with IFN gamma resulted in upregulation of MHC class I and antigen processing genes in the neuron cell bodies. IFN gamma-induced MHC class I molecules were also anterogradely transported into the distal axon. Interpretation: These results provide conclusive evidence that human axons are competent to express MHC class I molecules, suggesting that inflammatory factors enriched in demyelinated lesions may render axons vulnerable to attack by autoreactive CD8+ T cells in patients with MS. Future work will be aimed at identifying pathogenic anti-axonal T cells in these patients. PMID- 29468179 TI - Cell transplantation strategies for acquired and inherited disorders of peripheral myelin. AB - Objective: To investigate transplantation of rat Schwann cells or human iPSC derived neural crest cells and derivatives into models of acquired and inherited peripheral myelin damage. Methods: Primary cultured rat Schwann cells labeled with a fluorescent protein for monitoring at various times after transplantation. Human-induced pluripotent stem cells (iPSCs) were differentiated into neural crest stem cells, and subsequently toward a Schwann cell lineage via two different protocols. Cell types were characterized using flow cytometry, immunocytochemistry, and transcriptomics. Rat Schwann cells and human iPSC derivatives were transplanted into (1) nude rats pretreated with lysolecithin to induce demyelination or (2) a transgenic rat model of dysmyelination due to PMP22 overexpression. Results: Rat Schwann cells transplanted into sciatic nerves with either toxic demyelination or genetic dysmyelination engrafted successfully, and migrated longitudinally for relatively long distances, with more limited axial migration. Transplanted Schwann cells engaged existing axons and displaced dysfunctional Schwann cells to form normal-appearing myelin. Human iPSC-derived neural crest stem cells and their derivatives shared similar engraftment and migration characteristics to rat Schwann cells after transplantation, but did not further differentiate into Schwann cells or form myelin. Interpretation: These results indicate that cultured Schwann cells surgically delivered to peripheral nerve can engraft and form myelin in either acquired or inherited myelin injury, as proof of concept for pursuing cell therapy for diseases of peripheral nerve. However, lack of reliable technology for generating human iPSC-derived Schwann cells for transplantation therapy remains a barrier in the field. PMID- 29468180 TI - Is seizure frequency variance a predictable quantity? AB - Background: There is currently no formal method for predicting the range expected in an individual's seizure counts. Having access to such a prediction would be of benefit for developing more efficient clinical trials, but also for improving clinical care in the outpatient setting. Methods: Using three independently collected patient diary datasets, we explored the predictability of seizure frequency. Three independent seizure diary databases were explored: SeizureTracker (n = 3016), Human Epilepsy Project (n = 93), and NeuroVista (n = 15). First, the relationship between mean and standard deviation in seizure frequency was assessed. Using that relationship, a prediction for the range of possible seizure frequencies was compared with a traditional prediction scheme commonly used in clinical trials. A validation dataset was obtained from a separate data export of SeizureTracker to further verify the predictions. Results: A consistent mathematical relationship was observed across datasets. The logarithm of the average seizure count was linearly related to the logarithm of the standard deviation with a high correlation (R2 > 0.83). The three datasets showed high predictive accuracy for this log-log relationship of 94%, compared with a predictive accuracy of 77% for a traditional prediction scheme. The independent validation set showed that the log-log predicted 94% of the correct ranges while the RR50 predicted 77%. Conclusion: Reliably predicting seizure frequency variability is straightforward based on knowledge of mean seizure frequency, across several datasets. With further study, this may help to increase the power of RCTs, and guide clinical practice. PMID- 29468181 TI - Seizure semiology: an important clinical clue to the diagnosis of autoimmune epilepsy. AB - Objective: The purpose of this study is to analyze the seizure semiologic characteristics of patients with autoimmune epilepsy (AE) and describe the investigation characteristics of AE using a larger sample size. Methods: This observational retrospective case series study was conducted from a tertiary epilepsy center between May 2014 and March 2017. Cases of new-onset seizures were selected based on laboratory evidence of autoimmunity. At the same time, typical mesial temporal lobe epilepsy (MTLE) patients with hippocampal sclerosis (HS) were recruited as the control group from the subjects who underwent presurgical evaluation during the same period. Results: A total of 61 patients with AE were identified. Specific autoimmune antibodies were detected in 39 patients (63.93%), including anti-VGKC in 23 patients (37.70%), anti-NMDA-R in 9 patients (14.75%), anti-GABAB-R in 6 patients (9.84%), and anti-amphiphysin in 1 patient (1.64%). Regarding the seizure semiology, no significant differences were noted between AE patients with autoantibody and patients with suspected AE without antibody. Compared to typical MTLE patients with HS, both AE patients with autoantibody and patients with suspected AE without antibody had the same seizure semiologic characteristics, including more frequent SPS or CPS, shorter seizure duration, rare postictal confusion, and common sleeping SGTC seizures. Significance: This study highlights important seizure semiologic characteristics of AE. Patients with autoimmune epilepsy had special seizure semiologic characteristics. For patients with autoimmune epilepsy presenting with new-onset seizures in isolation or with a seizure-predominant neurological disorder, the special seizure semiologic characteristics may remind us to test neuronal nuclear/cytoplasmic antibodies early and initiate immunomodulatory therapies as soon as possible. Furthermore, the absence of neural-specific autoantibodies does not rule out AE. PMID- 29468182 TI - GLS loss of function causes autosomal recessive spastic ataxia and optic atrophy. AB - We describe a consanguineous family in which two brothers were affected by childhood onset spastic ataxia with optic atrophy and loss of motor and language skills. Through a combination of homozygosity mapping and whole-genome sequencing, we identified a homozygous copy number variant in GLS as the cause. The duplication leads to complete knockout of GLS expression. GLS encodes the brain- and kidney-specific enzyme glutaminase, which hydrolyzes glutamine for the production of glutamate, the most abundant central nervous system neurotransmitter. This is the first report implicating GLS loss of function in human disease. PMID- 29468183 TI - Charcot Marie Tooth disease type 4J with complex central nervous system features. AB - We describe a family with Charcot Marie Tooth disease type 4J presenting with features of Charcot Marie Tooth disease plus parkinsonism and aphemia. Genetic testing found two variants in the FIG4 gene: c.122T>C (p.I41T) - the most common Charcot Marie Tooth disease type 4J variant - and c.1949-10T>G (intronic). Proband fibroblasts showed absent FIG4 protein on western blot, and skipping of exon 18 by RT-PCR. As most patients with Charcot Marie Tooth disease type 4J do not have central nervous system deficits, we postulate the intronic variant and I41T mutation together are causing loss of FIG4 protein and subsequently the central nervous system findings in our family.

AB - The in vitro limiting dilution assay is used to determine the colorectal cancer initiating cell (CC-IC) frequency of a CC-IC enriched suspension culture, grown in growth factor enriched serum free media. The in vivo limiting dilution assay is used to determine the colorectal cancer initiating cell frequency of a primary colorectal cancer sample or an established suspension cell line using immunocompromised murine xenograft models. In vitro and vivo limiting dilution assays (LDAs) can be used to determine the effect of a specific treatment or genetic knockdown strategy on the initiating cell frequency of a population of CC ICs or colorectal cancer sample, respectively. PMID- 29468184 TI - Translational potential of human brain organoids. AB - The recent technology of 3D cultures of cellular aggregates derived from human stem cells have led to the emergence of tissue-like structures of various organs including the brain. Brain organoids bear molecular and structural resemblance with developing human brains, and have been demonstrated to recapitulate several physiological and pathological functions of the brain. Here we provide an overview of the development of brain organoids for the clinical community, focusing on the current status of the field with an critical evaluation of its translational value. PMID- 29468186 TI - Repetitive Questioning II. AB - Repetitive questioning is a major problem for caregivers, particularly taxing if they are unable to recognize and understand the reasons why their loved one keeps asking the same question over and over again. Caregivers may be tempted to believe that the patient does not even try to remember the answer given or is just getting obnoxious. This is incorrect. Repetitive questioning is due to the underlying disease: The patient's short term memory is impaired and he is unable to register, encode, retain and retrieve the answer. If he is concerned about a particular topic, he will keep asking the same question over and over again. To the patient each time she asks the question, it is as if she asked it for the first time. Just answering repetitive questioning by providing repeatedly the same answer is not sufficient. Caregivers should try to identify the underlying cause for this repetitive questioning. In an earlier case study, the patient was concerned about her and her family's safety and kept asking whether the doors are locked. In this present case study, the patient does not know how to handle the awkward situation he finds himself in. He just does not know what to do. He is not able to adjust to the new unexpected situation. So he repeatedly wants to reassure himself that he is not intruding by asking the same question over and over again. We discuss how the patient's son-in-law could have avoided this situation and averted the catastrophic ending. PMID- 29468187 TI - Sociodemographic Factors and Health-Related Characteristics That Influence the Quality of Life of Grandparent Caregivers in Zimbabwe. AB - Very few studies have examined quality of life (QOL) in elderly carers of orphaned children in African settings. This study explored sociodemographic factors and health-related characteristics that influence QOL of grandparent carers in Zimbabwe. A cross-sectional study stratified by district was done to collect information on socioeconomic factors, health-related characteristics, and QOL of grandparent carers (N = 327; age: M = 62.4, SD = 11.2). Data were collected on socioeconomic factors, self-perceived health, health care access, chronic disease condition, health insurance status, types of health care services, and medications taken using the World Health Organization Quality of Life Questionnaire (WHOQOL-BREF). Bivariate and multivariate analyses were used to investigate the associations between QOL and the predictor variables. Caregivers' level of education (odds ratio [OR] = 3.0; confidence interval [95% CI] = [1.0, 27]), fostering orphans only (OR = 0.4; 95% CI = [0.2, 0.7]), self perceived health (OR = 10.2; 95% CI = [4.5, 25]), medical insurance (OR = 9.8; 95% CI = [1.9, 54]), and satisfaction with health care services (OR = 2.2; 95% CI = [1.2, 4.4]) were associated with QOL, after adjusting for all influencing factors. The results confirm that QOL is compromised by specific demographic and self-rated health characteristics. Thus, eradicating poverty and providing services and changing caregiver's perceptions about self-rated health may enhance QOL among grandparent caregivers. PMID- 29468188 TI - The association between non-standard employment, job insecurity and health among British adults with and without intellectual impairments: Cohort study. AB - We sought to investigate the association between employment conditions and health among working age British adults with and without intellectual impairments. Using data from the 1970 British Cohort Study, we undertook a series of cross sectional analyses of the association between employment conditions and health (self reported general health, mental health) among British adults with and without intellectual impairments at ages 30, 34 and 42. Our results indicated that: (1) British adults with intellectual impairments were more likely than their peers to be exposed to non-standard employment conditions and experience job insecurity; (2) in both groups exposure was typically associated with poorer health; (3) British adults with intellectual impairments in non-standard employment conditions were more likely than their peers to transition to economic inactivity; (4) among both groups, transitioning into employment was associated with positive health status and transitioning out of employment was associated with poorer health status. British adults with intellectual impairments are significantly more likely than their peers to be exposed to non-standard and more precarious working conditions. The association between employment conditions and health was similar for British adults with and without intellectual impairments. As such, the study found no evidence to suggest that research on causal pathways between employment and health derived from studies of the general population should not generalize to the population of people with intellectual impairments. PMID- 29468189 TI - Cytosolic ATP Relieves Voltage-Dependent Inactivation of T-Type Calcium Channels and Facilitates Excitability of Neurons in the Rat Central Medial Thalamus. AB - The central medial nucleus (CeM) is a part of the intralaminar thalamus, which is involved in the control of arousal and sensory processing. However, ionic conductances and mechanisms that regulate the activity of the CeM are not well studied. Here, we used in vitro electrophysiology in acute brain slices from adolescent rats to demonstrate that T-type calcium currents (T-currents) are prominent in the majority of the studied CeM neurons and are critical determinants of low-threshold calcium spikes (LTSs), which in turn regulate excitability of these neurons. Using an ATP-free internal solution decreased T current density and induced a profound hyperpolarizing shift in steady-state inactivation curves while voltage-dependent activation kinetics were spared. Furthermore, selective pharmacological blockade of T-channels or use of an ATP free solution reduced both tonic action potential (AP) frequency and rebound burst firing in CeM neurons. Our results indicate that T-channels are critical regulators of a thalamocortical circuit output and suggest that cytosolic ATP could be an endogenous regulatory mechanism in which T-channels may functionally gate sensory transmission and arousal in vivo. PMID- 29468190 TI - Optogenetic Activation of Non-Nociceptive Abeta Fibers Induces Neuropathic Pain Like Sensory and Emotional Behaviors after Nerve Injury in Rats. AB - Neuropathic pain is caused by peripheral nerve injury (PNI). One hallmark symptom is allodynia (pain caused by normally innocuous stimuli), but its mechanistic underpinning remains elusive. Notably, whether selective stimulation of non nociceptive primary afferent Abeta fibers indeed evokes neuropathic pain-like sensory and emotional behaviors after PNI is unknown, because of the lack of tools to manipulate Abeta fiber function in awake, freely moving animals. In this study, we used a transgenic rat line that enables stimulation of non-nociceptive Abeta fibers by a light-activated channel (channelrhodopsin-2; ChR2). We found that illuminating light to the plantar skin of these rats with PNI elicited pain like withdrawal behaviors that were resistant to morphine. Light illumination to the skin of PNI rats increased the number of spinal dorsal horn (SDH) Lamina I neurons positive to activity markers (c-Fos and phosphorylated extracellular signal-regulated protein kinase; pERK). Whole-cell recording revealed that optogenetic Abeta fiber stimulation after PNI caused excitation of Lamina I neurons, which were normally silent by this stimulation. Moreover, illuminating the hindpaw of PNI rats resulted in activation of central amygdaloid neurons and produced an aversion to illumination. Thus, these findings provide the first evidence that optogenetic activation of primary afferent Abeta fibers in PNI rats produces excitation of Lamina I neurons and neuropathic pain-like behaviors that were resistant to morphine treatment. This approach may provide a new path for investigating circuits and behaviors of Abeta fiber-mediated neuropathic allodynia with sensory and emotional aspects after PNI and for discovering novel drugs to treat neuropathic pain. PMID- 29468191 TI - A Neural Circuit Mechanism for the Involvements of Dopamine in Effort-Related Choices: Decay of Learned Values, Secondary Effects of Depletion, and Calculation of Temporal Difference Error. AB - Dopamine has been suggested to be crucially involved in effort-related choices. Key findings are that dopamine depletion (i) changed preference for a high-cost, large-reward option to a low-cost, small-reward option, (ii) but not when the large-reward option was also low-cost or the small-reward option gave no reward, (iii) while increasing the latency in all the cases but only transiently, and (iv) that antagonism of either dopamine D1 or D2 receptors also specifically impaired selection of the high-cost, large-reward option. The underlying neural circuit mechanisms remain unclear. Here we show that findings i-iii can be explained by the dopaminergic representation of temporal-difference reward prediction error (TD-RPE), whose mechanisms have now become clarified, if (1) the synaptic strengths storing the values of actions mildly decay in time and (2) the obtained-reward-representing excitatory input to dopamine neurons increases after dopamine depletion. The former is potentially caused by background neural activity-induced weak synaptic plasticity, and the latter is assumed to occur through post-depletion increase of neural activity in the pedunculopontine nucleus, where neurons representing obtained reward exist and presumably send excitatory projections to dopamine neurons. We further show that finding iv, which is nontrivial given the suggested distinct functions of the D1 and D2 corticostriatal pathways, can also be explained if we additionally assume a proposed mechanism of TD-RPE calculation, in which the D1 and D2 pathways encode the values of actions with a temporal difference. These results suggest a possible circuit mechanism for the involvements of dopamine in effort-related choices and, simultaneously, provide implications for the mechanisms of TD-RPE calculation. PMID- 29468192 TI - Short-Term Depression of Axonal Spikes at the Mouse Hippocampal Mossy Fibers and Sodium Channel-Dependent Modulation. AB - Axonal spike is an important upstream process of transmitter release, which directly impacts on release probability from the presynaptic terminals. Despite the functional significance, possible activity-dependent modulation of axonal spikes has not been studied extensively, partly due to inaccessibility of the small structures of axons for electrophysiological recordings. In this study, we tested the possibility of use-dependent changes in axonal spikes at the hippocampal mossy fibers, where direct recordings from the axon terminals are readily feasible. Hippocampal slices were made from mice of either sex, and loose patch clamp recordings were obtained from the visually identified giant mossy fiber boutons located in the stratum lucidum of the CA3 region. Stimulation of the granule cell layer of the dentate gyrus elicited axonal spikes at the single bouton which occurred in all or none fashion. Unexpected from the digital nature of spike signaling, the peak amplitude of the second spikes in response to paired stimuli at a 50-ms interval was slightly but reproducibly smaller than the first spikes. Repetitive stimuli at 20 or 100 Hz also caused progressive use-dependent depression during the train. Notably, veratridine, an inhibitor of inactivation of sodium channels, significantly accelerated the depression with minimal effect on the initial spikes. These results suggest that sodium channels contribute to use-dependent depression of axonal spikes at the hippocampal mossy fibers, possibly by shaping the afterdepolarization (ADP) following axonal spikes. Prolonged depolarization during ADP may inactivate a fraction of sodium channels and thereby suppresses the subsequent spikes at the hippocampal mossy fibers. PMID- 29468193 TI - SCCmecFinder, a Web-Based Tool for Typing of Staphylococcal Cassette Chromosome mec in Staphylococcus aureus Using Whole-Genome Sequence Data. AB - Typing of methicillin-resistant Staphylococcus aureus (MRSA) is important in infection control and surveillance. The current nomenclature of MRSA includes the genetic background of the S. aureus strain determined by multilocus sequence typing (MLST) or equivalent methods like spa typing and typing of the mobile genetic element staphylococcal cassette chromosome mec (SCCmec), which carries the mecA or mecC gene. Whereas MLST and spa typing are relatively simple, typing of SCCmec is less trivial because of its heterogeneity. Whole-genome sequencing (WGS) provides the essential data for typing of the genetic background and SCCmec, but so far, no bioinformatic tools for SCCmec typing have been available. Here, we report the development and evaluation of SCCmecFinder for characterization of the SCCmec element from S. aureus WGS data. SCCmecFinder is able to identify all SCCmec element types, designated I to XIII, with subtyping of SCCmec types IV (2B) and V (5C2). SCCmec elements are characterized by two different gene prediction approaches to achieve correct annotation, a Basic Local Alignment Search Tool (BLAST)-based approach and a k-mer-based approach. Evaluation of SCCmecFinder by using a diverse collection of clinical isolates (n = 93) showed a high typeability level of 96.7%, which increased to 98.9% upon modification of the default settings. In conclusion, SCCmecFinder can be an alternative to more laborious SCCmec typing methods and is freely available at https://cge.cbs.dtu.dk/services/SCCmecFinder. IMPORTANCE SCCmec in MRSA is acknowledged to be of importance not only because it contains the mecA or mecC gene but also for staphylococcal adaptation to different environments, e.g., in hospitals, the community, and livestock. Typing of SCCmec by PCR techniques has, because of its heterogeneity, been challenging, and whole-genome sequencing has only partially solved this since no good bioinformatic tools have been available. In this article, we describe the development of a new bioinformatic tool, SCCmecFinder, that includes most of the needs for infection control professionals and researchers regarding the interpretation of SCCmec elements. The software detects all of the SCCmec elements accepted by the International Working Group on the Classification of Staphylococcal Cassette Chromosome Elements, and users will be prompted if diverging and potential new elements are uploaded. Furthermore, SCCmecFinder will be curated and updated as new elements are found and it is easy to use and freely accessible. PMID- 29468194 TI - Treatment of HIV-Infected Individuals with the Histone Deacetylase Inhibitor Panobinostat Results in Increased Numbers of Regulatory T Cells and Limits Ex Vivo Lipopolysaccharide-Induced Inflammatory Responses. AB - Histone deacetylase inhibitors (HDACi) modulate the transcriptional activity of all cells, including innate and adaptive immune cells. Therefore, we aimed to evaluate immunological effects of treatment with the HDACi panobinostat in HIV infected patients during a clinical phase IIa latency reversal trial. Using flow cytometry, we investigated changes in T cell activation (CD69, CD38, HLA-DR) and the expression of CD39 and CTLA4 on regulatory T cells (Tregs). Whole-blood stimulations were performed and cytokine responses measured using Luminex. Gene expression in purified peripheral blood mononuclear cells (PBMCs) was evaluated using an Affymetrix HTA 2.0 gene chip. We found that proportions of CD4+ and CD8+ T cells expressing CD69 increased 24 h after initial panobinostat administration (P < 0.01), followed by an increase in the proportions of CD38+ HLA-DR+ coexpressing CD4+ T cells on day 4 (P = 0.02). Concurrently, proportions of Tregs increased by 40% (P = 0.003). Treg CTLA4 median fluorescent intensity (MFI) increased by 25% (P = 0.007), and CD39 MFI on CD39+ Treg increased by 12% (P = 0.02). Lipopolysaccharide (LPS)-induced inflammatory responses (interleukin-1beta [IL-1beta], IL-6, IL-12p40, and tumor necrosis factor alpha [TNF-alpha]) in whole blood were significantly downregulated 4 days after initial dosing. Lastly, panobinostat induced significant changes in the overall gene expression pattern (fold change, >1.5; false-discovery-rate [FDR]-corrected P, <0.05). Importantly, measures of immune function returned to baseline after panobinostat treatment and follow-up revealed no sustained effect on overall gene expression. IMPORTANCE The effect of treatment with histone deacetylase inhibitors on the immune system in HIV-infected individuals is not clear. Analysis of results from a clinical trial in which 15 HIV-infected individuals received 12 doses of panobinostat identified a significant impact on both T cell activation status and regulatory T cell suppressive marker expression and a reduced level of monocytic responsiveness to inflammatory stimuli. These changes were substantiated by global gene expression analysis. Collectively, the results suggest that panobinostat has multiple effects on innate and adaptive immune responses. Importantly, all the effects were transient, and further panobinostat treatment did not cause persistent long term changes in gene expression patterns in HIV-infected individuals. PMID- 29468195 TI - Transcriptome Profiling Reveals Interplay of Multifaceted Stress Response in Escherichia coli on Exposure to Glutathione and Ciprofloxacin. AB - We have previously reported that supplementation of exogenous glutathione (GSH) promotes ciprofloxacin resistance in Escherichia coli by neutralizing antibiotic induced oxidative stress and by enhancing the efflux of antibiotic. In the present study, we used a whole-genome microarray as a tool to analyze the system level transcriptomic changes of E. coli on exposure to GSH and/or ciprofloxacin. The microarray data revealed that GSH supplementation affects redox function, transport, acid shock, and virulence genes of E. coli. The data further highlighted the interplay of multiple underlying stress response pathways (including those associated with the genes mentioned above and DNA damage repair genes) at the core of GSH, offsetting the effect of ciprofloxacin in E. coli. The results of a large-scale validation of the transcriptomic data using reverse transcription-quantitative PCR (RT-qPCR) analysis for 40 different genes were mostly in agreement with the microarray results. The altered growth profiles of 12 different E. coli strains carrying deletions in the specific genes mentioned above with GSH and/or ciprofloxacin supplementation implicate these genes in the GSH-mediated phenotype not only at the molecular level but also at the functional level. We further associated GSH supplementation with increased acid shock survival of E. coli on the basis of our transcriptomic data. Taking the data together, it can be concluded that GSH supplementation influences the expression of genes of multiple stress response pathways apart from its effect(s) at the physiological level to counter the action of ciprofloxacin in E. coli. IMPORTANCE The emergence and spread of multidrug-resistant bacterial strains have serious medical and clinical consequences. In addition, the rate of discovery of new therapeutic antibiotics has been inadequate in last few decades. Fluoroquinolone antibiotics such as ciprofloxacin represent a precious therapeutic resource in the fight against bacterial pathogens. However, these antibiotics have been gradually losing their appeal due to the emergence and buildup of resistance to them. In this report, we shed light on the genome-level expression changes in bacteria with respect to glutathione (GSH) exposure which act as a trigger for fluoroquinolone antibiotic resistance. The knowledge about different bacterial stress response pathways under conditions of exposure to the conditions described above and potential points of cross talk between them could help us in understanding and formulating the conditions under which buildup and spread of antibiotic resistance could be minimized. Our findings are also relevant because GSH-induced genome-level expression changes have not been reported previously for E. coli. PMID- 29468198 TI - Paraganglioma of Urinary Bladder Managed by Laparoscopic Partial Cystectomy in Conjunction with Flexible Cystoscopy: A Case Report. AB - Background: Paraganglioma of the urinary bladder (PUB) is exceedingly rare, accounting for <0.1% of all urinary bladder tumors. Various challenging treatment options are available. Case Presentation: A 67-year-old female presented with malignant hypertension on four medications for which investigation was done. An observation of having functioning PUB was noted. She was admitted and laparoscopic partial cystectomy was done with the guidance of flexible cystoscopy. She had a smooth postoperative course and was discharged home, then catheter was removed after cystogram. Histopathology confirmed the diagnosis of a bladder paraganglioma. Finally, during the last follow-up, the patient was asymptomatic with controlled blood pressure and normalized catecholamine levels with no evidence of recurrence. Conclusion: PUB is an exceedingly rare tumor that can be managed with minimally invasive techniques such as laparoscopic partial cystectomy with cystoscopy guidance. PMID- 29468196 TI - Altered Distribution of RNA Polymerase Lacking the Omega Subunit within the Prophages along the Escherichia coli K-12 Genome. AB - The RNA polymerase (RNAP) of Escherichia coli K-12 is a complex enzyme consisting of the core enzyme with the subunit structure alpha2betabeta'omega and one of the sigma subunits with promoter recognition properties. The smallest subunit, omega (the rpoZ gene product), participates in subunit assembly by supporting the folding of the largest subunit, beta', but its functional role remains unsolved except for its involvement in ppGpp binding and stringent response. As an initial approach for elucidation of its functional role, we performed in this study ChIP chip (chromatin immunoprecipitation with microarray technology) analysis of wild type and rpoZ-defective mutant strains. The altered distribution of RpoZ defective RNAP was identified mostly within open reading frames, in particular, of the genes inside prophages. For the genes that exhibited increased or decreased distribution of RpoZ-defective RNAP, the level of transcripts increased or decreased, respectively, as detected by reverse transcription-quantitative PCR (qRT-PCR). In parallel, we analyzed, using genomic SELEX (systemic evolution of ligands by exponential enrichment), the distribution of constitutive promoters that are recognized by RNAP RpoD holoenzyme alone and of general silencer H-NS within prophages. Since all 10 prophages in E. coli K-12 carry only a small number of promoters, the altered occupancy of RpoZ-defective RNAP and of transcripts might represent transcription initiated from as-yet-unidentified host promoters. The genes that exhibited transcription enhanced by RpoZ-defective RNAP are located in the regions of low-level H-NS binding. By using phenotype microarray (PM) assay, alterations of some phenotypes were detected for the rpoZ deleted mutant, indicating the involvement of RpoZ in regulation of some genes. Possible mechanisms of altered distribution of RNAP inside prophages are discussed. IMPORTANCE The 91-amino-acid-residue small-subunit omega (the rpoZ gene product) of Escherichia coli RNA polymerase plays a structural role in the formation of RNA polymerase (RNAP) as a chaperone in folding the largest subunit (beta', of 1,407 residues in length), but except for binding of the stringent signal ppGpp, little is known of its role in the control of RNAP function. After analysis of genomewide distribution of wild-type and RpoZ-defective RNAP by the ChIP-chip method, we found alteration of the RpoZ-defective RNAP inside open reading frames, in particular, of the genes within prophages. For a set of the genes that exhibited altered occupancy of the RpoZ-defective RNAP, transcription was found to be altered as observed by qRT-PCR assay. All the observations here described indicate the involvement of RpoZ in recognition of some of the prophage genes. This study advances understanding of not only the regulatory role of omega subunit in the functions of RNAP but also the regulatory interplay between prophages and the host E. coli for adjustment of cellular physiology to a variety of environments in nature. PMID- 29468199 TI - A Large Stone Within a Ureteroceles: A Diagnostic Pitfall and the Utility of Holmium Laser Deroofing as a Viable Surgical Option. AB - We describe a case of a partial unilateral duplex system and ureterocele containing a 4 cm stone in a 66-year-old woman who presented with renal colic. Cystoscopic stone removal and deroofing of the ureterocele were performed and a ureteral stent was placed for a total of 6 weeks. Our case is unique as it highlighted the diagnostic pitfalls of ureteroceles, especially when obscured by a large calculus. We also described the use of a Holmium laser to simultaneously incise the ureterocele and fragment the calculus. PMID- 29468197 TI - Genomewide Transcriptional Responses of Iron-Starved Chlamydia trachomatis Reveal Prioritization of Metabolic Precursor Synthesis over Protein Translation. AB - Iron is essential for growth and development of Chlamydia. Its long-term starvation in cultured mammalian cells leads to production of aberrant noninfectious chlamydial forms, also known as persistence. Immediate transcriptional responses to iron limitation have not been characterized, leaving a knowledge gap of how Chlamydia regulates its response to changes in iron availability. We used the fast-chelating agent 2,2'-bipyridyl (BPDL) to homogeneously starve Chlamydia trachomatis serovar L2 of iron, starting at 6 or 12 h postinfection. Immediate transcriptional responses were monitored after only 3 or 6 h of BPDL treatment, well before formation of aberrant Chlamydia. The first genomewide transcriptional response of C. trachomatis to iron starvation was subsequently determined utilizing RNA sequencing. Only 7% and 8% of the genome were differentially expressed in response to iron starvation at the early and middle stages of development, respectively. Biological pathway analysis revealed an overarching theme. Synthesis of macromolecular precursors (deoxynucleotides, amino acids, charged tRNAs, and acetyl coenzyme A [acetyl CoA]) was upregulated, while energy-expensive processes (ABC transport and translation) were downregulated. A large fraction of differentially downregulated genes are involved in translation, including those encoding ribosome assembly and initiation and termination factors, which could be analogous to the translation downregulation triggered by stress in other prokaryotes during stringent responses. Additionally, transcriptional upregulation of DNA repair, oxidative stress, and tryptophan salvage genes reveals a possible coordination of responses to multiple antimicrobial and immunological insults. These responses of replicative-phase Chlamydia to iron starvation indicate a prioritization of survival over replication, enabling the pathogen to "stock the pantry" with ingredients needed for rapid growth once optimal iron levels are restored. IMPORTANCE By utilizing an experimental approach that monitors the immediate global response of Chlamydia trachomatis to iron starvation, clues to long standing issues in Chlamydia biology are revealed, including how Chlamydia adapts to this stress. We determined that this pathogen initiates a transcriptional program that prioritizes replenishment of nutrient stores over replication, possibly in preparation for rapid growth once optimal iron levels are restored. Transcription of genes for biosynthesis of metabolic precursors was generally upregulated, while those involved in multiple steps of translation were downregulated. We also observed an increase in transcription of genes involved in DNA repair and neutralizing oxidative stress, indicating that Chlamydia employs an "all-or-nothing" strategy. Its small genome limits its ability to tailor a specific response to a particular stress. Therefore, the "all-or-nothing" strategy may be the most efficient way of surviving within the host, where the pathogen likely encounters multiple simultaneous immunological and nutritional insults. PMID- 29468200 TI - Robot-Assisted Perineal Radical Prostatectomy in a Post-Kidney Transplant Recipient. AB - Background: After almost two decades, transabdominal robotic radical prostatectomy techniques have been fully developed and are widely practiced by many robotic urologists. Recently, a transperineal robotic radical prostatectomy, a technique not yet popular to many, was introduced as an alternative approach in patients with previous abdominal surgery. Here, we present our unique experience with robotic perineal radical prostatectomy (r-PRP) on a kidney transplant recipient. Case Presentation: A 71-year-old man who had a kidney transplant 4 months previously was diagnosed with prostate cancer (PCa) and underwent r-PRP using the da Vinci Xi robotic system. The operative time was 110 minutes and blood loss was minimal. After the perineal drain was removed on postoperative day 3, the patient was discharged. The urethral catheter was subsequently removed on postoperative day 8. Pathologic analysis revealed localized PCa with negative surgical margins. Conclusion: The r-PRP offers all the advantages of minimally invasive surgery. Moreover, in a kidney transplant recipient, it provides additional benefits, such as avoidance of allograft vascular and ureteral injuries, while maintaining an equivalent oncologic efficacy and surgical safety compared with its transabdominal counterpart. PMID- 29468201 TI - Toward a More Humanistic American Medical Profession: An Analysis of Premedical Web Sites From Ohio's Undergraduate Institutions. AB - In response to changes in health care, American medical schools are transforming their curricula to cultivate empathy, promote professionalism, and increase cultural competency. Many scholars argue that an infusion of the humanities in premedical and medical training may help achieve these ends. This study analyzes Web-based messaging of Ohio's undergraduate institutions to assess premedical advising attitudes toward humanities-based coursework and majors. Results suggest that although many institutions acknowledge the humanities, most steer students toward science majors; strong advocates of the humanities tend to have religious or other special commitments, and instead of acknowledging the intrinsic value that the humanities might have for future physicians, most institutions promote the humanities because entrance exams now contain related material. PMID- 29468202 TI - Pramipexole-induced antecollis in patients with Parkinson's disease: Two cases and literature review. AB - Antecollis is considered to be relatively rare in Parkinson's disease (PD). Few cases of dopamine agonist-induce antecollis in PD have been reported. We described literature review of 12 PD patients including our 2 cases with pramipexole (PPX)-induced antecollis. The patients were predominantly Japanese, women and above 3 of Hoehn and Yahr stage. PPX-induced antecollis in PD was considered a type of dystonia of flexor neck muscle, and was improved soon after cessation or reduction of PPX. Our two cases improved their antecollis by overnight changing from PPX to ropinirole without deteriorating motor functions. Overnight switching of DA was considered useful as one option in the treatment of antecollis. PMID- 29468203 TI - Inner retinal vasculopathy in Zika virus disease. AB - Purpose: Zika virus infection is associated with vision-threatening ocular complications including uveitis and outer retinopathy. The aim of this report is to describe a case of an adult patient with serologically confirmed Zika infection who presented with retinal vascular abnormalities that coincided with systemic post-viral neurological manifestations of the disease. Observations: A 34-year-old white female presented with symptoms of peripheral neuropathy following serologically confirmed Zika virus infection that was acquired in Puerto Rico four months prior to presentation. Ocular evaluation revealed perifoveal microaneurysms which were not associated with visual symptoms. Conclusions and importance: These data potentially expand the phenotypic spectrum of Zika virus retinopathy. In addition to outer retinal abnormalities which are well-described in infants and adults, inner retinal vascular abnormalities may also occur and may be temporally associated with post-viral neurological sequelae of Zika virus infection. Clinicians should be aware of potential retinal involvement in affected patients who present with neurological symptoms after recovery from acute Zika virus infection. PMID- 29468204 TI - Orbital apex syndrome from bacterial sinusitis without orbital cellulitis. AB - Purpose: To describe a case of orbital apex syndrome as a result of isolated bacterial sinusitis. Observations: A 63-year-old woman presented with an orbital apex syndrome from isolated bacterial sinusitis with rapidly declining visual acuity to no light perception. We compared our case with 6 similar cases of severe vision loss from isolated bacterial sinusitis. In contrast to previously published cases, our patient presented with good vision yet deteriorated to no light perception despite appropriate treatment. Conclusions and importance: Orbital apex syndrome can present as a constellation of cranial neuropathies including optic neuropathy from conditions affecting the orbital apex. Although vision loss remained permanent, prompt initiation of broad-spectrum antibiotics and antifungals and surgical intervention prevented further extension of infection into intracranial structures. PMID- 29468205 TI - Late-onset bleb-associated endophthalmitis and continuous positive airway pressure. AB - Purpose: To raise awareness of a possible association between continuous positive airway pressure (CPAP) devices and postoperative bleb-related infection. Observations: A 57-year old patient on CPAP presented with unilateral bleb associated endophthalmitis 32 months after routine ExPress Trabeculectomy with mitomycin C. The offending organism, Streptococcus mitis, is a nonmotile and generally non-virulent pathogen which predominates in the normal human respiratory flora. Conclusions and importance: This conceptual report underscores a potential relationship between CPAP use and bleb-associated endophthalmitis. Streptococcal species are the most commonly reported causative organisms in bleb associated endophthalmitis, and S. mitis is of particular concern as the most abundant microbe among all human oral flora. A logical risk factor for infection, the CPAP device may inadvertently deliver such organisms to the vulnerable conjunctival filtering bleb. PMID- 29468206 TI - Severe visual loss and recovery post trabeculectomy- A case report. AB - Purpose: Glaucoma is a progressive optic neuropathy and a leading cause of blindness. Neural losses from glaucoma are irreversible, and so the aim of glaucoma treatment is to slow progression and minimize the risk of further damage. Visual loss post filtration surgery in patients with advanced glaucomatous optic nerve damage is a rare but dreaded complication. Functional improvement is not expected. We report the case of a patient who experienced a significant loss of vision following glaucoma surgery that was followed by late visual recovery. We will also review the literature regarding this phenomenon. Case presentation/Observations: A 60-year old male presented with a history of right pseudoexfoliative glaucoma and uncontrolled intraocular pressure(IOP) on medical and laser treatment. He underwent a successful right Mitomycin C augmented trabeculectomy combined with phacoemulsification. Unexpectedly, he experienced a marked decrease in vision from 0.3 to hand motion with no identifiable explanation. The loss of vision continued for almost 4 months before a significant improvement in vision occurred and his visual acuity came up to 0.6. Although the mechanism of loss or improved vision cannot be proven, it is likely that post operative IOP spikes which were repeatedly above 30 mmHg in the first week, resulted in ganglion cell dysfunction rather than apoptosis which can explain the improvement in vision in the later months when pressure was maintained at target. Conclusion: and Importance: Although rare, Wipe out phenomenon is possible in the setting of advanced glaucomatous optic neuropathy. However, functional improvements may occur following IOP control. Glaucoma surgery should be offered early to those with advanced disease. PMID- 29468207 TI - Bull's eye maculopathy and subfoveal deposition in two mucopolysaccharidosis type I patients on long-term enzyme replacement therapy. AB - Purpose: To report retinal findings in two patients with mucopolysaccharidosis type I (MPS I) receiving human recombinant alpha-l-iduronidase (Laronidase) as enzyme replacement therapy. Observations: Patient 1 had visual acuity 20/20 right eye, 20/25 left eye and unremarkable anterior segment and retinal examination. Optical coherence tomography (OCT) scanning demonstrated parafoveal thinning and subfoveal hyperreflectant material. Patient 2 had visual acuity 20/20 both eyes, with dense nuclear cataract both eyes. Retinal examination demonstrated bull's eye maculopathy both eyes. OCT scanning confirmed parafoveal atrophy and demonstrated similar appearing subfoveal hyperreflectant material, more prominent than in case 1. Conclusions and importance: These two patients with MPS I receiving Laronidase treatment have developed bull's eye maculopathy changes and subfoveal deposition of hyperreflectant material despite excellent compliance and good tolerance of the standard dose of enzyme therapy for this disorder. Further studies are required to determine the nature of the material, the incidence and the effect of enzyme replacement therapy on these findings in patients with MPS I. PMID- 29468208 TI - Novel use of fibrin sealant for scleral suture free placement of a glaucoma drainage device in advanced scleral thinning. AB - Purpose: This reports a case using fibrin glue to secure a glaucoma drainage device plate to the sclera where there is a concern with the use of suture. Observations: A 13-year-old patient with congenital aniridia and associated glaucoma refractory to topical medications underwent implantation of a glaucoma drainage device (GDD) for improved intraocular pressure (IOP) control. The patient had substantial scleral thinning with staphyloma formation, potentially making the use of traditional suturing techniques problematic. Fibrin glue was used to attach the GDD plate, as well the tube and patch graft which has been previously described, without sutures. The patient tolerated the procedure well with a 41% reduction in IOP at six months follow-up with no migration of the GDD from its original position. Conclusions and importance: The use of fibrin glue in ophthalmology can be expanded to include attachment of the GDD plate to the sclera in patients with suturing contraindications. PMID- 29468209 TI - Juvenile xanthogranuloma involving concurrent iris and skin: Clinical, pathological and molecular pathological evaluations. AB - Purpose: To report a case of juvenile xanthogranuloma involving the iris and skin that clincally was diagnosed with an obvious cutaneous lesion. Observations: A four month-old girl with hyphema and increased intraocular pressure of the left eye persisting for 2 weeks. A suspicious yellow-brown mass with nodular surface and traversed by irregular vascularization was noted on the inferior iris surface. Ultrasound biomicroscopy (UBM; 35 MHz) of the mass revealed multiple nodular irregular hyperreflective lesions in the peripheral iris. Using a biopsy of an obvious cutaneous abdominal skin lesion a diagnosis was made based on histopathological analyses. The biopsy showed dense dermal infiltrate consisting of foamy histiocytes. Additional stains revealed CD68 positivity and CD1a and S100 negativity. This mass revealed histopathologic features identical to juvenile xanthogranuloma and was concurrent with the iris lesion. Next-generation sequencing using Ion AmpliSeqTM Cancer Hotspot Panel revealed a missense mutation of FGFR3 (p.F386L). Conclusion and importance: The diagnosis of a xanthogranuloma of the iris with hyphema can be made easier in patients with obvious cutaneous lesions as described in our case. The significance of FGFR3 mutation in association with JXG is unknown and should be further investigated. PMID- 29468210 TI - Removal of choroidal neovascular membrane in a case of macular hole after anti VEGF therapy for age-related macular degeneration. AB - Purpose: The formation of macular hole after receiving anti-vascular endothelial growth factor (anti-VEGF) therapy is rare. We report a case of macular hole that occurred after intravitreal injection of an anti-VEGF agent for age-related macular degeneration (AMD) in a patient, who underwent vitrectomy combined with choroidal neovascularization (CNV) removal. Observations: A 64-year-old female with AMD affecting her right eye received an intravitreal injection of an anti VEGF agent. After treatment, we identified a full thickness macular hole (MH) that was associated with the rapid resolution of the macular edema and contraction of the CNV. After performing vitrectomy combined with CNV removal, the MH closed and her visual acuity improved. Examination of the removed CNV revealed a network of microvessels devoid of pericytes. Conclusions: and Importance: The present findings suggest that rapid resolution of macular edema and contraction of the CNV and/or mild increase in the vitreous traction after anti-VEGF therapy could potentially cause MH. CNV removal via the MH may be an acceptable procedure, if the MH remains open, the CNV is of the classic type, and it spares a central portion of the fovea. PMID- 29468211 TI - Treatment of retinal pigment epithelial detachment secondary to exudative age related macular degeneration. AB - Purpose: This pilot study evaluated the combination of photodynamic therapy (PDT) and anti-vascular endothelial growth factor (anti-VEGF) as a treatment in patients with a pigment epithelial detachment (PED) due to exudative age-related degeneration (AMD). Methods: We analyzed seven consecutive patients between September 1, 2015 and September 1, 2017 with a PED secondary to exudative AMD who were treated with full fluence standard PDT and a series of monthly intravitreal anti-VEGF injections. Follow-up ranged between 3 and 24 months. Variables collected for the purpose of this study included baseline best-corrected visual acuity converted to logMAR (logarithm of minimum angle of resolution), central macular thickness, and maximum PED height. This information was then reviewed at subsequent follow-ups. Results: The PED completely resolved in 4/7 eyes while three patients had a significant improvement in PED size with a corresponding improvement in visual acuity. Initial PED heights ranged from 147 to 423 MUm and was reduced by an average of 255.7 MUm (83.2% average reduction, range -143 to - 405 MUm). Initial CMT ranged from 223 to 719 MUm and was reduced by an average of 225.7 MUm (54.4% average reduction, range -88 to - 529 MUm). Mean logMAR VA improved from 0.669 (Snellen equivalent 20/93, [20/40 to 20/200]) to 0.269 (Snellen equivalent 20/37, [20/25 to 20/80]) at last follow-up. No complications were observed in our patients. Conclusions and Importance: PED in the setting of exudative AMD showed an excellent response to a combined multimodal approach that includes PDT with intravitreal anti-VEGF injection followed by a monthly anti VEGF schedule. Most importantly, visual acuity showed a significant improvement from baseline. If confirmed by future studies, this would offer another treatment avenue for this difficult-to-treat consequence of exudative AMD. PMID- 29468212 TI - Retinal pigment epithelium changes in pediatric patients with glaucoma drainage devices. AB - Purpose: Retinal changes secondary to hypotony are usually described as wrinkling or folding of the inner portion of the choroid, the retinal pigment epithelium (RPE), and the outer retinal layers in the macular area due to scleral wall collapse. We describe a new retinal finding in children with suspected hypotony after implantation of Baerveldt Glaucoma Implant (BGI). Observations: Four patients in our series developed significant RPE defects after BGI implant. The RPE defects appeared as elongated white lines observed solely in the posterior pole, in no particular pattern, and seemed to be worse in infants with anterior segment dysgenesis and with collagen disorders. Conclusion and importance: Children have thinner and more elastic scleral walls than adults. This characteristic may cause the inward scleral wall to collapse when the eye is hypotonic. The resulting redundancy of the retina leads to wrinkling and RPE defects characterized by hypopigmented lines predominantly in the macular area. Such findings, to our knowledge, have not been previously reported in pediatric patients. PMID- 29468213 TI - Acute-onset endophthalmitis caused by Staphylococcus lugdunensis. AB - Purpose: To report a series of patients with acute-onset bacterial endophthalmitis caused by culture proven Staphylococcus lugdunensis, and to characterize clinical outcomes and microbiologic susceptibilities of this organism. Observations: The study included six eyes of 6 patients. The etiologies included cataract surgery (3), open globe injury (2), and intravitreal injection (1). Isolates of S. lugdunensis demonstrated sensitivity to vancomycin in all cases reported. Three of 6 isolates of S. lugdunensis demonstrated resistance to oxacillin and 1 isolate demonstrated resistance to ciprofloxacin. Best-corrected visual acuity was >=20/400 in 6/6 (100%) of eyes and >=20/40 in 3/6 (50%) of cases. Conclusion and importance: Acute-onset endophthalmitis caused by S. lugdunensis is associated with variable visual outcomes. Vancomycin provides consistent coverage of acute-onset endophthalmitis cause by S. lugdunensis. PMID- 29468214 TI - Optical coherence tomography angiography showing perifoveal capillary stability 30 years after fluorescein angiography. AB - Purpose: To report the Optical Coherence Tomography Angiography (OCTA) results as a novel non-invasive diagnostic modality which provides useful information regarding the status of blood flow in diabetic retinopathy. The current study is a long-term follow-up of eyes of patients with proliferative diabetic retinopathy managed with panretinal photocoagulation. Observations: Two patients with proliferative diabetic retinopathy (PDR) were treated with panretinal photocoagulation (PRP) in both eyes in the early 1980s. Fluorescein angiography performed at the baseline visit and follow-up Optical Coherence Tomography Angiography performed at 30 years after initial PRP treatment showed remarkable stability of the perifoveal capillary network. Visual acuity initially and at last follow-up remained 20/25 or better in these patients. Conclusions and importance: Fluorescein angiography and Optical Coherence Tomography Angiography demonstrated that the integrity of the perifoveal capillary network remained remarkably stable at 30 years. Similarly, the visual outcomes were stable inspite of advanced PDR at baseline. PMID- 29468215 TI - Descemet membrane endothelial keratoplasty for corneal decompensation due to iridoschisis. AB - Purpose: To report a case of bilateral iridoschisis with cataracts and corneal decompensation in a patient who underwent cataract extraction and superficial iridectomy followed by Descemet membrane endothelial keratoplasty (DMEK). Observations: A 58-year-old man with previously diagnosed iridoschisis, cataracts, and diabetes mellitus experienced progressive vision loss bilaterally due to corneal decompensation. Slit lamp examination revealed iridoschisis with iris fibrils contacting the corneal endothelium, stromal edema, and mild guttate changes bilaterally. Corneal findings were more severe in the right eye, including the presence of bullous keratopathy at the time of presentation. Cataract extraction with intraocular lens implantation and superficial iridectomy were performed in the right eye, followed by DMEK. These same procedures were performed subsequently in the left eye. Postoperatively, the patient had significant improvement in visual acuity and corneal edema. Conclusions and importance: DMEK can be performed safely and successfully after staged cataract surgery with superficial iridectomy in eyes with endothelial decompensation caused by iridoschisis. PMID- 29468216 TI - Central retinal artery occlusion during vitrectomy: Immediate retinal revascularization following induction of posterior vitreous detachment. AB - Purpose: To describe a patient with acute central retinal artery occlusion (CRAO) during vitrectomy surgery and the possible role of vitrectomy in acute CRAO management. Observations: An 84-year-old man presented with broad vitreomacular traction and epiretinal membrane in the right eye. Preoperative assessment clearly showed normal retinal vasculature. On starting vitrectomy, complete CRAO with marked segmentation of all retinal vessels was noted. Vitrectomy was performed in the usual manner and once the posterior hyaloid detached from the disc, immediate complete revascularization of the retinal vessels was noted. The patient had a complete visual recovery. Conclusions and importance: Immediate vitrectomy with induction of posterior vitreous detachment may have a role in selected cases of acute CRAO, particularly if performed within a short window. PMID- 29468217 TI - Ranibizumab-induced retinal reperfusion and regression of neovascularization in diabetic retinopathy: An angiographic illustration. AB - Purpose: To report regression of neovascularization and reperfusion of ischemic areas of the retina on Wide-field Digital Fluorescein Angiography following anti vascular endothelial growth factor injections in a patient with active Proliferative Diabetic Retinopathy. Observations: Case report of sixty-one-year old male patient with proliferative diabetic retinopathy and diabetic macular edema documented on wide field digital fluorescein angiography. The patient was treated with three intravitreal injections of ranibizumab given at monthly intervals. Repeat angiography after third intravitreal injection revealed complete regression of new vessels. Moreover, there was evident improvement in perfusion in the previously noted ischemic areas of the retina. Conclusion and importance: Intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections are a valuable treatment option for reversing neovascularization in eyes with proliferative diabetic retinopathy with fewer side effects when compared to standard pan-retinal photocoagulation. Additionally, we also illustrate restoration of retinal perfusion post anti-VEGF therapy indicative of pre-existingsalvageableischemic retina tissue. PMID- 29468218 TI - Intravitreal bevacizumab as therapy for refractory neovascular glaucoma secondary to iris metastasis of breast carcinoma. AB - Purpose: To report a case of refractory glaucoma secondary to iris metastasis from breast cancer which was successfully treated with intravitreal bevacizumab. Observations: A 72-year-old woman presented with left ocular pain, vision loss and neovascular glaucoma secondary to iris metastasis from breast cancer. A single intravitreal injection of bevacizumab resulted in prolonged resolution of iris neovascularization, reduction of intraocular pressure and ocular pain relief. Iris tumor regression was later noted following the reinstatement of systemic chemotherapy. Conclusions & importance: A single intravitreal bevacizumab injection may be sufficient to achieve palliative control of neovascular glaucoma secondary to iris breast cancer metastasis. To our knowledge, this is the first case report in which a single intravitreal bevacizumab injection was used for the effective management of this condition. PMID- 29468219 TI - Retinal vasproliferative tumor in a case of X-linked retinoschisis detachment. AB - Purpose: To describe the first published case of X-linked retinoschisis (XLRS) detachment with retinal vasoproliferative tumor (RVPT) and provide a literature review of the subject. Observations: The authors describe a case of a 17 year old male with X-linked retinoschisis who presented with a retinal detachment and a retinal vasoproliferative tumor. The patient was treated with pars plana vitrectomy, endolaser, subtenon's kenalog and anti-VEGF (vascular endothelial growth factor) intravitreal injections. He regained 20/60 vision with a flat macula and had significant resolution of the associated vasoproliferative leakage seen on fluorescein angiography. Conclusions and importance: This case adds XLRS to the conditions associated with RVPT and gives support for treatment with laser photocoagulation and anti-VEGF therapy with bevacizumab to control the exudative process. PMID- 29468220 TI - Optical coherence tomography angiography changes in radial peripapillary capillaries in Leber hereditary optic neuropathy. AB - Purpose: To present a report of longitudinal changes in radial peripapillary capillaries (RPC) and changes in retinal full thickness (RFT) and peripapillary retinal nerve fiber layer (RNFL) in a patient with Leber hereditary optic neuropathy (LHON). Observations: A 42-year-old man presented with acute- and presymptomatic-stage LHON in the left (OS) and right (OD) eyes, respectively, at the initial visit. Onset of LHON in the OD was observed 2 months after the initial visit. Once the temporal RNFL started to decrease in thickness, the areas of temporal RPC defects and RFT thinning gradually increased, indicating that these factors might be correlated. Conclusions and importance: Optical coherence tomography angiography showed LHON from the presymptomatic stage. The results indicate that temporal RPC defects and RFT thinning start to spread once the pseudoedema begins to resolve. PMID- 29468221 TI - Spectral optical coherence tomography findings in an elderly patient with syphilitic bilateral chronic panuveitis. AB - Purpose: To report the spectral domain optical coherence tomography (SD-OCT) features of a focal retinitis in an elderly male patient with bilateral syphilitic panuveitis. Observations: In the left eye (LE), spectral domain SD-OCT images during the active period revealed hyperreflectivity extending through the full thickness of the retina with no individualization of the layers, except for the retinal pigment epithelium. Once the lesion healed, SD-OCT imaging revealed an inner retinal atrophy and a mild disruption of the retinal pigment epithelium. Conclusions and importance: In our patient, treponemal infection seemed to produce full-thickness retinal damage with partial involvement of the retinal pigment epithelium. The severe retinal damage, in this case, led to a poorer visual outcome than in other forms of syphilitic retinal involvement. PMID- 29468222 TI - Clinical features, antimicrobial susceptibilities, and treatment outcomes of patients with culture positive endophthalmitis after penetrating keratoplasty. AB - Purpose: To report the clinical features organisms and treatment outcomes in patients with endophthalmitis after penetrating keratoplasty (PK). Methods: Retrospective noncomparative case series. Results: Eleven eyes of 11 patients with culture positive endophthalmitis after PK were included. The time to diagnosis of endophthalmitis from last PK was less than 1 week in 3/11 (27%), between 1 and 4 weeks in 3/11 (27%), and greater than one month in 5/11 (46%) (range 2-924 days). The distribution of isolates included gram positive (GP) 9/11 (82%), gram negative (GN) 1/11 (9%), and fungal 1/11 (9%) species, respectively. Of GP bacteria tested, 9/9 (100%) were sensitive to Vancomycin. Of fungal isolates tested, none (0/1) were sensitive to Amphoteracin, Fluconazole, and/or Voriconazole. Among patients with rim culture data available, 1/7 (14%) donor rims were culture positive for Candida glabrata and 6/7 (86%) were culture negative. Patients were treated with primary tap and inject in 10/11 (91%) and primary vitrectomy in 1/11 (9%). VA of >=5/200 was present in 2/11 (18%) at time of endophthalmitis diagnosis, and was recorded in 6/11 (55%) at last follow-up. Conclusions and Importance: Patients with endophthalmitis after PK presented at variable time points after surgery. Gram positive organisms were the most common isolate. VA outcomes after treatment were generally poor. PMID- 29468223 TI - A case of hypertrophic herpes simplex virus affecting the eyelid and cornea masquerading as IgG4-related disease. AB - Purpose: To report a case of hypertrophic herpes simplex virus (HSV) of the eyelid and cornea masquerading as IgG4-related disease. Observations: A 37-year old African American female with a past medical history of human immunodeficiency virus (HIV) on highly active antiretroviral therapy (HAART) and a recent history of treated genital herpes, presented with an ulcerative lesion of the left upper and lower eyelids, and severe ocular inflammation with symblepharon. Initially, eyelid biopsy revealed findings consistent with IgG4-related disease, and the patient was treated with high dose oral prednisone. After one week of therapy, there was no improvement in the patient's symptoms, and she subsequently developed a corneal epithelial defect which progressed to chronic ulceration. Repeat biopsy and corneal cultures revealed herpes simplex virus type 2. The patient was treated with high dose acyclovir, and the lid lesion improved. The conjunctival inflammation and corneal epithelial defect resolved but symblepharon restricting her eye movement remained. She also developed corneal vascularization and opacification causing severe vision loss. Conclusions and importance: Chronic hypertrophic herpes simplex virus infection is a rare condition reported in patients with HIV. While there have been few reports of hypertrophic HSV affecting the eyelid, this is the first reported case of hypertrophic HSV affecting the eye, resulting in severe vision loss. PMID- 29468224 TI - Optical coherence tomography angiography of a pigmented Fuchs' adenoma (age related hyperplasia of the nonpigmented ciliary body epithelium) masquerading as a ciliary body melanoma. AB - Purpose: To report a case of age-related hypertrophy of the nonpigmented ciliary epithelium (ARH-NPCE) clinically resembling a ciliary body melanoma and report the optical coherence tomography angiography (OCTA) findings associated with this lesion. Observations: A 51-year-old male was referred for evaluation of a deeply pigmented ciliary body mass with extension through the iris root. Iridocyclectomy was performed due to concern for ciliary body melanoma. Histopathologic analysis was instead consistent with ARH-NPCE, also known as Fuchs' adenoma. Prior to surgery, OCTA images revealed abnormal vasculature in the area of the lesion. Vessels in the peripheral iris approaching the lesion appeared more tortuous and were non-radial as compared with normal iris vessels. The ciliary body mass itself could not be penetrated using an OCTA system operating at 1050 nm. Conclusions and importance: ARH-NPCE may clinically resemble a pigmented ciliary body melanoma. This is the second case describing this clinical scenario, which may be more common than previously thought. Non-invasive imaging with OCTA revealed an abnormal peripheral iris vasculature pattern in the area of the iridociliary mass characterized by disorganized, tortuous, and non-radial vessels. Despite advances in longer wavelength OCTA systems, poor penetration of the ciliary body lesion precluded imaging of the intratumoral vessels in this location. PMID- 29468225 TI - Multimodal imaging of macular subretinal deposits following intravitreal ocriplasmin injection. AB - Purpose: Ocriplasmin is effective in closing macular holes due to vitreomacular traction. We present a case of macular subretinal material deposition observed with spectral-domain optical coherence tomography (SD-OCT) and multimodal imaging, following successful closure of a macular hole following intravitreal ocriplasmin injection. Observations: An 81-year-old male presented with decreased vision in the left eye due to a full-thickness macular hole secondary to vitreomacular traction. Ocriplasmin (Jetrea) was injected into the vitreous and hole closure was observed after one week. Macular subretinal material deposition developed along the outer surface of the resultant serous detachment on OCT one week post-injection. Fluorescein angiography demonstrated no expanding hyperfluorescence due to retinal or choroidal leak, or staining of the lesion. The material was mildly autofluorescent. The macular subretinal material complex spontaneously decreased with no significant effect on vision over 60 weeks. Conclusions and importance: Macular subretinal material deposition has not previously been reported following intravitreal ocriplasmin injection. This material is likely composed of photoreceptor outer segments. It is important to recognize that macular subretinal deposits can occur following intravitreal ocriplasmin injection as it may cause diagnostic confusion and potentially influence the visual and anatomical outcomes following successful hole closure. PMID- 29468226 TI - Immunoglobulin G4-related dacyroadenitis presenting as bilateral chorioretinal folds from severely enlarged lacrimal glands. AB - Purpose: To describe a case of immunoglobulin G4 (IgG4)-related dacyroadenitis presenting as bilateral chorioretinal folds from eyeball compression by massively enlarged lacrimal glands. Observations: A 51-year-old woman with severely enlarged bilateral lacrimal glands was diagnosed as having IgG4-related dacryoadenitis. The glands strongly compressed the globes, forming chorioretinal folds resembling those found in orbital malignancy. Eventual treatment with oral prednisolone dramatically reduced the volume of the lacrimal glands and released globe compression on magnetic resonance imaging. However, the chorioretinal folds remained in the right fundus and symptoms of blurred vision improved but persisted. Conclusions and importance: This is the first account of chorioretinal fold formation by severely enlarged lacrimal glands appearing in IgG4-related dacryoadenitis. Chorioretinal fold formation by an enlarged lacrimal gland occurring bilaterally may represent a basis for suspecting IgG4-related dacryoadenitis. Prompt treatment is recommended for patients presenting with very large lacrimal glands to avoid visual impairment. PMID- 29468227 TI - Solitary mastocytoma in the eyelid of an adult. AB - Purpose: To describe the ophthalmic symptoms and histopathological findings in a rare case of an eyelid mastocytoma in an adult. Observations: A man in his early 60s developed a painless, non-tender, non-pruritic, mobile nodule on the right lower eyelid beneath the inferior orbital rim. The lesion grew to 15 * 9 mm over eleven months. Biopsy revealed a diffuse infiltrate of histiocytoid and spindle shaped mast cells forming cords and small nests between collagen fibers in the superficial and deep dermis. Mast cell lineage was confirmed by immunohistochemistry. Physical examination revealed no other cutaneous lesions and no evidence of systemic disease. Serum tryptase level was normal. Annual full body examination by a dermatologist for 4.5 years has revealed neither recurrence in the eyelid nor cutaneous involvement at other sites. Conclusions and importance: Mast cell tumors limited to the human eyelid are extremely uncommon with only four previously reported cases, including one in an adult. This case highlights the rare possibility of a solitary mastocytoma presenting in the eyelid of an adult. PMID- 29468229 TI - Penetrating probability and cross section of the Li+-C60 encapsulation process through an ab initio molecular dynamics investigation. AB - The endohedral complex system of Li+-C60 has been shown to possess interesting applications in photovoltaics, supramolecular chemistry, and functionalized materials. In this study, we perform a theoretical investigation of Li+ encapsulation within a C60 cage by employing an ab initio molecular dynamics approach. The Li+ cation is positioned 9 A away from the C60 center of mass, and fired towards a randomized spot in a six-membered ring with a certain level of inletting energy, which is 7.5 eV, 9 eV, 12 eV, or 15 eV. In total, 2000 samples of MD trajectories are investigated. Our statistical results yielded a penetrating probability in the range of 0.8% to 15.6% with respect to the above inletting energy, while the cross section ranges from 0.006 A2 to 0.123 A2. Moreover, we observed that the penetrating probability exhibited direct proportionality to the inletting energy. Hence, we can determine that the minimum required inletting energy for reaction occurrence is 6.6 eV. Overall, it seems difficult for Li+ to penetrate through the sp2-carbon wall, because a very high inletting energy is required to open the entrance. At the same time, Li+ must approach closely to the center of a six-membered ring to enhance the penetration probability. PMID- 29468228 TI - Two cases of differentiation syndrome with ocular manifestations in patients with acute promyelocytic leukaemia treated with all-trans retinoic acid and arsenic trioxide. AB - Purpose: To describe two cases of differentiation syndrome presenting with ocular manifestations including bilateral chorioretinopathy in patients with acute promyelocytic leukaemia treated with all-trans retinoic acid and arsenic trioxide differentiation therapy. Observations: This observational case series identifies two patients at a single tertiary institution diagnosed with differentiation syndrome with associated ophthalmic involvement. Both patients reported bilateral reduction in visual acuity at days fourteen and ten respectively following initiation of differentiation therapy in addition to developing other systemic manifestations of differentiation syndrome. Both patients received the same chemotherapeutic regimen including both all-trans retinoic acid and arsenic trioxide as well as ten days of routine differentiation syndrome prophylaxis with oral prednisolone. Case 1 presented with bilateral pale yellow sub-retinal lesions concentrated at the posterior poles with ocular coherence tomography (OCT) evidence of bilateral multifocal areas of focal RPE elevation and adhesion to the thickened outer retina with interspersed sub-retinal fluid. Fluorescein angiography revealed areas of early hyperflouresence corresponding to the yellow chorioretinal lesions with late diffuse leakage of fluid into the subretinal space. Case 2 presented with a similar characteristic retinal findings on fundoscopy and optical coherence tomography. Both patients experienced rapid improvement in the visual symptoms and marked resolution of the sub-retinal fluid within seven to fourteen days of onset with excellent long-term visual outcome. Both patients achieved molecular remission after induction and received standard consolidation and maintenance therapy without visual disturbance. Conclusion and importance: Ocular manifestations of differentiation syndrome have been only recently recognised. We present a case series of two patients with differentiation syndrome with ocular involvement. Common to both presentations was the presence of bilateral reduction in visual acuity with multifocal serous retinal detachment secondary to chorioretinopathy. The visual outcome from both presentations was excellent with rapid normalisation of visual acuity and resolution of the sub-retinal fluid with only the first case having their differentiation therapy temporarily withheld during the acute phase of illness. PMID- 29468230 TI - Simulation of colony pattern formation under differential adhesion and cell proliferation. AB - Proliferation of individual cells is one of the hallmarks of living systems, and collectively the cells within a colony or tissue form highly structured patterns, influencing the properties at the population level. We investigate the joint effect of proliferation in the form of cell division and cell sorting due to differential adhesion using a cellular automaton model. Through simulations and theoretical analysis akin to interface growth, we show that this model gives rise to slower than exponential growth in the case of a single cell type as well as novel colony patterns in the case of two cell types. In particular, engulfment of one cell type by the other is strongly enhanced compared to the prediction from the differential adhesion hypothesis in the absence of proliferation. These observations provide new insights in predicting and characterizing colony morphology using experimentally accessible information such as single cell growth rate and cell adhesion strength. PMID- 29468231 TI - Copper-catalyzed decarboxylative regioselective synthesis of 1,5-disubstituted 1,2,3-triazoles. AB - A copper-catalyzed decarboxylative regioselective protocol for the synthesis of 1,5-disubstituted 1,2,3-triazoles through direct annulation of cinnamic acids with aryl azides has been developed. This is the first example of 1,5 disubstituted 1,2,3-triazoles, under aerobic conditions using Cu(ii) as the catalyst, which were generally synthesized using a ruthenium(ii) catalyst. The simplicity and regioselectivity of this methodology, complementing to the classical CuAAC catalyzed the synthesis of 1,4-disubstituted 1,2,3-triazoles. PMID- 29468232 TI - The (photo)chemistry of Stenhouse photoswitches: guiding principles and system design. AB - Molecular photoswitches comprise chromophores that can be interconverted reversibly with light between two states with different photochemical and physicochemical properties. This feature renders them useful for diverse applications, ranging from materials science, biology (specifically photopharmacology) to supramolecular chemistry. With new and more challenging systems to control, especially extending towards biomedical applications, using visible or near-infrared light for photoswitch activation becomes vital. Donor acceptor Stenhouse adducts are a novel class of visible light-responsive negative photochromes that provide a possible answer to current limitations of other photoswitch classes in the visible and NIR window. Their rapid development since their discovery in 2014, together with first successful examples of applications, demonstrate both their potential and areas where improvements are needed. A better understanding of DASA characteristics and its photoswitching mechanism has revealed that they are in fact a subset of a more general structural class of photochromes, namely Stenhouse photoswitches. This tutorial review aims at providing an introduction and practical guide on DASAs: it focuses on their structure and synthesis, provides fundamental insights for understanding their photoswitching behavior and demonstrates guiding principles for tailoring these switches for given applications. PMID- 29468233 TI - Two-dimensional Fe3O4/MoS2 nanocomposites for a magnetorheological fluid with enhanced sedimentation stability. AB - Superparamagnetic Fe3O4 nanoparticles were successfully deposited on the surface of MoS2 nanosheets (Fe3O4/MoS2) by a sonochemical method and the obtained Fe3O4/MoS2 nanocomposites were used as a promising candidate for a magnetorheological (MR) fluid. This MR fluid was prepared from the Fe3O4/MoS2 nanocomposites and its corresponding MR performances were examined using a rotational rheometer. The MR fluid based on Fe3O4/MoS2 showed typical MR effects with increasing viscosity, shear stress, yield stress and dynamic shear modulus depending on the applied magnetic fields. Compared with commercial carbonyl iron (CI) particles, the sedimentation stability of the Fe3O4/MoS2-MR fluid was greatly improved because of its unique two-dimensional structure and the reduced fluid-particle density mismatch. Therefore, the prepared Fe3O4/MoS2-based MR fluid with typical MR effects and good sedimentation stability would have great potential in practical applications.

AB - The reactivity patterns of carbodiphosphoranes (CDPs) as ligands are much less explored than those of isoelectronic analogues. In the current manuscript, we investigate the reactivity of the carbodiphosphorane-based PCP nickel(ii) pincer complex [({dppm}2C)NiCl]Cl (1) towards acids and bases, calculate proton affinities, analyse the bonding situation and tautomeric forms with the aim to evaluate whether CDPs can potentially act as cooperative ligands in catalysis (dppm = 1,1-bis(diphenylphosphino)methane). Our investigations show that different tautomeric forms are stable for the coordinated and the uncoordinated ligand. The protonated CDP-based complex 2 represents a rare example of a cationic donor group binding to a cationic metal centre. The continuous arm deprotonation of 1 leads to the formation of remarkably stable dimers with Ni-C-P C-metallacycles. In comparison to corresponding boron and amine-based ligands, the coordinated CDP-group exhibits the lowest proton affinity according to DFT calculations, indicating that coordinated CDP ligands can potentially serve as proton relay in cooperative catalysis.

AB - A series of beta-quinolyl-enamino aluminium complexes [AlLMe2] 1-7 {L = [(2 C9H6N)-CH[double bond, length as m-dash]C(4-MeC6H4)-N(Ar)-], Ar = C6H5 (1), 4 FC6H4 (2), 3,4,5-F3C6H2 (3), C6F5 (4), 5-tBuC6H4 (5), 2,6-Me2C6H3 (6), and 2,6 iPr2C6H3 (7)} were synthesized by the reaction of AlMe3 with the corresponding beta-quinolyl-enamine ligands. All the complexes were characterized by 1H and 13C NMR spectroscopy and elemental analysis. The molecular structures of complexes 1 3 and 7 were confirmed by single-crystal X-ray diffraction, which revealed that all the Al atoms adopt a distorted tetrahedral geometry. These Al complexes were tested as the initiators for the ring-opening polymerization (ROP) of epsilon caprolactone (epsilon-CL). The polymerization results showed that 1-5 in the presence of BnOH proceeded efficiently and their catalytic behaviors toward the ROP of epsilon-CL were significantly affected by the substituents of the aryl ring (Ar) on the end of the enamino framework, where the placement of electron withdrawing substituents caused higher catalytic activity. However 6 and 7 displayed poor activity under the same conditions, suggesting that ortho substituents on the Ar moieties hamper the coordination-insertion of the epsilon CL monomer. The ROP of epsilon-CL by efficient binary catalytic systems proceeded in a living manner evidenced by the narrow PDIs and the linear nature of Mnversus conversion plots and monomer/catalyst ratios.

AB - We report on a molecular dynamics study on the relation between the structure and the orientational (and hydrogen bond) dynamics of hydration water around the ocean pout AFP III anti-freeze protein. We find evidence for an increasing tetrahedral structure from the area opposite to the ice binding site (IBS) towards the protein IBS, with the strongest signal of tetrahedral structure around the THR-18 residue of the IBS. The tetrahedral structural parameter mostly positively correlates with increased reorientation decay times. Interestingly, for several key (polar) residues that are not part of the IBS but are in its vicinity, we observe a decrease of the reorientation time with increasing tetrahedral structure. A similar anti-correlation is observed for the hydrogen bonded water molecules. These effects are enhanced at a lower temperature. We interpret these results in terms of the structure-making and structure-breaking residues. Moreover, we investigate the tetrahedral structure and dynamics of waters at a partially dehydrated IBS, and for the protein adsorbed at the air water interface. We find that the mutation changes the preferred protein orientation upon adsorption at an air-water interface. These results are in agreement with the water-air Vibration Sum Frequency Generation spectroscopic experiments showing a strongly reduced tetrahedral signal upon mutation at the IBS.

AB - Polymer brushes are widely used to prevent the adsorption of proteins, but the mechanisms by which they operate have remained heavily debated for many decades. We show conclusive evidence that a polymer brush can be a remarkably strong kinetic barrier towards proteins by using poly(ethylene glycol) grafted to the sidewalls of pores in 30 nm thin gold films. Despite consisting of about 90% water, the free coils seal apertures up to 100 nm entirely with respect to serum protein translocation, as monitored label-free through the plasmonic activity of the nanopores. The conclusions are further supported by atomic force microscopy and fluorescence microscopy. A theoretical model indicates that the brush undergoes a morphology transition to a sealing state when the ratio between the extension and the radius of curvature is approximately 0.8. The brush-sealed pores represent a new type of ultrathin filter with potential applications in bioanalytical systems.

AB - Peptide-based molecular electronic devices are promising due to the large diversity and unique electronic properties of biomolecules. These electronic properties can change considerably with peptide structure, allowing diverse design possibilities. In this work, we explore the effect of the side-chain of the peptide on its electronic properties, by using both experimental and computational tools to detect the electronic energy levels of two model peptides. The peptides include 2Ala and 2Trp as well as their 3-mercaptopropionic acid linker which is used to form monolayers on an Au surface. Specifically, we compare experimental ultraviolet photoemission spectroscopy measurements with density functional theory based computational results. By analyzing differences in frontier energy levels and molecular orbitals between peptides in gas-phase and in a monolayer on gold, we find that the electronic properties of the peptide side-chain are maintained during binding of the peptide to the gold substrate. This indicates that the energy barrier for the peptide electron transport can be tuned by the amino acid compositions, which suggests a route for structural design of peptide-based electronic devices. PMID- 29468243 TI - Improved mass spectrometric detection of acidic peptides by variations in the functional group pKa values of reverse micelle extraction agents. AB - Polymeric reverse micelles can be used to selectively extract peptides from complex mixtures via a two-phase extraction approach. In previous work, we have shown that the charge polarity of the hydrophilic functional group that is in the interior of the reverse micelle dictates the extraction selectivity. To investigate how the extraction is influenced by the inherent pKa of the functional group, we designed and tested a series of polymeric reverse micelles with variations in the hydrophilic functional group. From this series of polymers, we find that the extraction capability of the reverse micelles in an apolar phase is directly related to the aqueous phase pKa of the interior functional group, suggesting that the functional groups maintain their inherent chemistry even in the confined environment of the reverse micelle interior. Because these functional groups maintain their inherent pKa in the reverse micelle interior, they provide predictable extraction selectivity upon changes in aqueous phase pH. We exploit this finding to demonstrate that sulfonate containing polymers can be used to remove basic peptides from complex mixtures, thereby allowing the improved detection of acidic peptides. Using these new materials, we also demonstrate a new means of isoelectric point (pI) bracketing that allows the mass spectrometric detection of peptides with a defined and narrow range of pI values.

AB - Defect-rich tungsten disulfide (WS2) nanosheets are synthesized via a self template method, in which tungsten oxide is partially sulfurized to form WS2/WO3 nanosheets. The defect-rich WS2 nanosheets only require an overpotential of 145 mV to achieve a current density of 10 mA cm-2 with a Tafel slope of 58.5 mV dec-1 and exhibit excellent stability in 0.5 M H2SO4 electrolyte. PMID- 29468245 TI - Protonation-induced ultrafast torsional dynamics in 9-anthrylbenzimidazole: a pH activated molecular rotor. AB - We report the photophysical properties and excited state dynamics of 9 anthrylbenzimidazole (ANBI) which exhibits protonation-induced molecular rotor properties. In contrast to the highly emissive behavior of neutral ANBI, protonation of the benzimidazole group of ANBI induces efficient nonradiative deactivation by ultrafast torsional motion around the bond connecting the anthracene and benzimidazole units, as revealed by ultrafast transient absorption and fluorescence spectroscopy. Contrary to viscosity-independent fluorescence of neutral dyes, protonated ANBI is shown to display linear variation of emission yield and lifetime with solvent viscosity. The protonation-induced molecular rotor properties in the studied system are shown to be driven by enhanced charge transfer and are corroborated by quantum chemical calculations. Potential application as a microviscosity sensor of acidic regions in a heterogeneous environment by these proton-activated molecular rotor properties of ANBI is discussed.

AB - Damage of the mucosal barrier in HIV infection, microbial translocation, and immune activation can persist even in patients on successful antiretroviral therapy (ART) especially advanced late presenters. The aim of this study was to find factors that determine immune activation and bacterial translocation in HIV infected advanced late presenters on suppressive ART. Forty-three late presenters (CD4 < 200 cells/ul prior to ART) on successful ART (more than 2 years of ART) with optimal and suboptimal CD4 recovery were enrolled into this study. The serum concentrations of intestinal fatty acid-binding peptide (I-FABP), zonulin-1, programmed cell death-1 protein (PCDP-1), and soluble (s)CD14 were measured using the ELISA test. We found higher serum levels of I-FABP and sCD14 in successfully antiretroviral-treated advanced late presenters compared to healthy subjects (p < 0.0001 and p = 0.0004). The serum concentration of PCDP-1 and zonulin-1 in HIV infected patients did not differ from healthy controls. The levels of microbial translocation and immune activation markers were not associated with the degree of CD4 recovery. A serum concentration of I-FABP above 2.03 ng/ml was independently associated with a shorter ART (OR 0.78; p = 0.03). Older age was related to serum levels of sCD14 above 2.35 ug/ml (OR 1.1; p = 0.01). Higher serum levels of I-FABP and sCD14 in successfully antiretroviral-treated advanced late presenters compared to healthy subjects suggest an incomplete reconstruction of the intestinal barrier and sustained immune activation despite good CD4 recovery. It was not the CD4 level, but the length of the suppressive ART that was found to be associated with the restoration of the intestinal barrier. PMID- 29468258 TI - Intermuscular implantation technique for subcutaneous cardioverter defibrillators. AB - BACKGROUND: The conventional technique for subcutaneous implantable cardioverter defibrillator (S-ICD) implantation has been associated with pocket complications. The aim of this study was to evaluate the efficacy and safety of an alternative intermuscular technique for S-ICD implantation. METHODS: S-ICDs were implanted in ten consecutive patients (ten males, mean age: 46.8 +/- 14.7 years). The pocket for the pulse generator was made above the serratus anterior muscular fascia and beneath the latissimus dorsi muscle by detaching the fibrous tissue between the muscles. Electrode implantation was performed using the three- (n = 4) or the two incision technique (n = 6). RESULTS: All S-ICDs were successfully implanted in the absence of any procedure-related complications with a successful 65-J standard polarity defibrillation threshold testing, apart from one patient with Brugada syndrome who needed device repositioning more dorsally. During a mean follow-up of 16.5 +/- 7.3 months, no major complications requiring surgical repair were encountered, while patients demonstrated high levels of comfort and satisfaction with the cosmetic result. One patient experienced an inappropriate shock due to noise detection, which was resolved after reprogramming to a different sensing vector. CONCLUSION: The intermuscular technique is a safe and efficacious approach for S-ICD implantation. This technique could lead to fewer pocket-related complications and better cosmetic results. PMID- 29468259 TI - Palliative care in heart failure : A meta-analysis of randomized controlled trials. AB - BACKGROUND: Palliative care can play an important role in the management of heart failure. We conducted a systematic review and meta-analysis to compare the efficacy and safety of palliative care in patients with heart failure. METHODS: PubMed, Embase, Web of Science, EBSCO, and the Cochrane Library databases were systematically searched. Randomized controlled trials (RCTs) on the impact of palliative care on heart failure were included. Two investigators independently searched the articles, extracted data, and assessed the quality of included studies. The primary outcome was mortality. RESULTS: Seven RCTs were included in the meta-analysis. Compared with usual care for heart failure, palliative care was associated with a significantly increased quality of life (standardized mean difference = 1.46; 95% confidence interval [CI] = 0.12 to 2.79; p = 0.03) and reduced depression scores (standardized mean difference = -0.62; 95% CI = -0.99 to -0.25; p = 0.03), but demonstrated no impact on mortality (risk ratio [RR] = 1.28; 95% CI = 0.86 to 1.92; p = 0.22) and rehospitalization (RR = 0.84; 95% CI = 0.66 to 1.07; p = 0.16). CONCLUSION: Palliative care can improve the quality of life and reduce the occurrence of depression in patients with heart failure. PMID- 29468257 TI - Aurora kinase B regulates axonal outgrowth and regeneration in the spinal motor neurons of developing zebrafish. AB - Aurora kinase B (AurkB) is a serine/threonine protein kinase with a well characterised role in orchestrating cell division and cytokinesis, and is prominently expressed in healthy proliferating and cancerous cells. However, the role of AurkB in differentiated and non-dividing cells has not been extensively explored. Previously, we have described a significant upregulation of AurkB expression in cultured cortical neurons following an experimental axonal transection. This is somewhat surprising, as AurkB expression is generally associated only with dividing cells Frangini et al. (Mol Cell 51:647-661, 2013); Hegarat et al. (J Cell Biol 195:1103-1113, 2011); Lu et al. (J Biol Chem 283:31785-31790, 2008); Trakala et al. (Cell Cycle 12:1030-1041, 2014). Herein, we present the first description of a role for AurkB in terminally differentiated neurons. AurkB was prominently expressed within post-mitotic neurons of the zebrafish brain and spinal cord. The expression of AurkB varied during the development of the zebrafish spinal motor neurons. Utilising pharmacological and genetic manipulation to impair AurkB activity resulted in truncation and aberrant motor axon morphology, while overexpression of AurkB resulted in extended axonal outgrowth. Further pharmacological inhibition of AurkB activity in regenerating axons delayed their recovery following UV laser-mediated injury. Collectively, these results suggest a hitherto unreported role of AurkB in regulating neuronal development and axonal outgrowth.

PMID- 29468261 TI - In Vivo Molecular Profiling of Human Glioma : Cross-Sectional Observational Study Using Dynamic Susceptibility Contrast Magnetic Resonance Perfusion Imaging. AB - PURPOSE: To assess the diagnostic performance of dynamic susceptibility contrast perfusion magnetic resonance perfusion imaging (DSC-MRI) for in vivo human glioma molecular profiling. METHODS: In this study 100 patients with histopathologically confirmed glioma who provided written informed consent were retrospectively assessed between January 2016 and February 2017 in two prospective trials that were approved by the local institutional review board. Cerebral blood volume (CBV) measurements from DSC-MRI were assessed, and histogram parameters of relative CBV (rCBV) results were compared among World Health Organization (WHO) 2016 based histological findings and molecular characteristics. A classification and regression tree (CART) algorithm with 10-fold cross-validation was used to calculate the diagnostic accuracy. RESULTS: The 90th percentile (C90) of rCBV was significantly lower in patients with the isocitrate dehydrogenase 1/2 (IDH1/2) mutation (2.86 +/- 1.21; p < 0.001) and loss of alpha-thalassemia mental retardation syndrome X-linked (ATRX) expression (2.23 +/- 0.91; p < 0.001) than in those with the IDH1/2 wild type (4.78 +/- 2.34) and maintained ATRX expression (4.30 +/- 2.02). The standard deviation (SD) of rCBV was significantly higher in glioblastoma (GBM) with methylated O6-methylguanine DNA methyltransferase (MGMT; 1.99 +/- 0.73; p = 0.001) than in those with unmethylated MGMT (1.20 +/- 0.45). In CART analysis, rCBV predicted the molecular subgroup in 76.3% of astroglial tumors; however, the diagnostic performance was reduced to 48.1% by including oligodendrogliomas with chromosome 1p/19q co-deletion in the analysis due to substantial overlap of rCBV values between OD1p/19q-LOH and IDHwt GBM. CONCLUSION: The DSC-MRI procedure may provide insight into the IDH1/2 mutation and ATRX expression status and MGMT methylation profile of diffuse glioma; however, taking integrated oligodendroglioma into account limits the diagnostic performance of rCBV in non-invasively predicting the molecular subtype. PMID- 29468263 TI - Assessment of Detection Methods and Vegetation Associations for Introduced Finlayson's Squirrels (Callosciurus finlaysonii) in Italy. AB - Managing biological invasions requires rapid, cost-effective assessments of introduced species' occurrence, and a good understanding of the species' vegetation associations. This is particularly true for species that are elusive or may spread rapidly. Finlayson's squirrel (Callosciurus finlaysonii) is native to Thailand and southeastern Asia, and two introduced populations occur in peninsular Italy. One of the two introduced populations is rapidly expanding, but neither effective monitoring protocols nor reliable information on vegetation associations are available. To fill this gap, we conducted visual surveys and hair tube sampling in a periurban landscape of southern Italy to compare the effectiveness of these two methods in assessing presence of Finlayson's squirrel. We also determined the species' association with vegetation types at detection locations and nesting sites. Both visual and hair tube sampling effectively assessed the species' presence, but hair tubes resulted in fewer false absences. Moreover, when we controlled for the costs of labor and equipment, hair tubes were 33.1% less expensive than visual sampling. Presence of squirrels and their nests was positively correlated with shrub species richness, indicating that the occurrence of forests with well-developed understory may inhibit the spread of the species. PMID- 29468262 TI - A Consensus-Based Criterion Standard for the Requirement of a Trauma Team. AB - BACKGROUND: Trauma team activation (TTA) represents a considerable expenditure of trauma centre resources. It is mainly triggered by field triage criteria. The overall quality of the criteria may be evaluated based on the rate of over- and undertriage. However, there is no gold standard that defines which adult patients truly require a trauma team. The objective of this study was to develop consensus based criteria defining the necessity for a trauma team. METHODS: A consensus group was formed by trauma specialists experienced in emergency and trauma care with a specific interest in field triage and having previously participated in guideline development. A literature search was conducted to identify criteria that have already been used or suggested. The initial list of criteria was discussed in two Delphi round and two consensus conferences. The entire process of discussion and voting was highly standardized and extensively documented, resulting in a final list of criteria. RESULTS: Initially 95 criteria were identified. This was subsequently reduced to 20 final criteria to appropriately indicate the requirement for attendance of a trauma team. The criteria address aspects related to injury severity, admission to an intensive care unit, death within 24 h, need for specified invasive procedures, need for surgical and/or interventional radiological procedures, and abnormal vital signs within a defined time period. CONCLUSIONS: The selected criteria may be applied as a tool for research and quality control concerning TTA. However, future studies are necessary to further evaluate for possible redundancy in criteria that may allow for further reduction in criteria. PMID- 29468264 TI - The accuracy of free hand resection in limb salvage surgery of bone tumours. AB - PURPOSE: Resection length should be designed before limb salvage surgery of bone tumours. The aim of this study was to evaluate the accuracy of free hand resections. METHODS: Two hundred forty-eight cases were enrolled, including 173 osteosarcomas, 24 giant cell tumours, 16 chondrosarcomas, seven spindle cell sarcomas, 14 bone metastases, three undifferentiated pleomorphic sarcomas, three Ewing sarcomas, two angiosarcomas, and six other bone and soft tissue tumours. One hundred forty-six were located in the femur, 75 in the tibia, 19 in the humerus, six in the radius, one in the ulna, and one in the fibula. The resection length was included in the pre-operative plan. After surgery, we measure the length of specimens. Both lengths were compared. The patients were classified by tumour location. RESULTS: The range of length difference was from - 21 to 29 mm. The mean absolute value of the differences was 8.0 +/- 6.3 mm. Altogether, 173 cases (69.8%) had an absolute difference value of <= 10 mm, 66 cases (26.6%) of 10-20 mm, and only 9 cases (3.6%) of > 20 mm. The average length of gross specimens (164.1 +/- 43.3 mm) was longer than planned lengths (160.7 +/- 44.2 mm); p < 0.001. CONCLUSIONS: The differences were significant in the distal femur and proximal tibia. Even though, the accuracy of free hand resection is acceptable in this method. PMID- 29468265 TI - The tridimensional geometry of the proximal femur should determine the design of cementless femoral stem in total hip arthroplasty. AB - PURPOSE: Using a cementless femoral stem in total hip arthroplasty (THA), optimal filling of the proximal femoral metaphyseal volume (PFMV) and restoration of the extramedullary proximal femoral (PF) parameters (i.e., femoral offset (FO), neck length (FNL), and head height (FHH)) constitute key goals for optimal hip biomechanics, functional outcome, and THA survivorship. However, almost 30% of mismatch between the PF anatomy and implant geometry of the most widely implanted non-modular cementless femoral stem has been demonstrated in a computed tomography scan (CT scan) study. Therefore, this anatomic study aimed to evaluate the relationship between the intra- and extramedullary PF parameters using tridimensional CT scan reconstructions. METHODS: One hundred fifty-one CT scans of adult healthy hips were obtained from 151 male Caucasian patients (mean age = 66 +/- 11 years) undergoing lower limb CT scan arteriography. Tridimensional PF reconstructions and parameter measurements were performed using a corrected PF coronal plane-defined by the femoral neck and diaphyseal canal longitudinal axes to avoid influence of PF helitorsion and femoral neck version on extramedullary PF parameters. RESULTS: Independently of the femoral neck-shaft angle, the PFMV was significantly and positively correlated with the FO, FNL, and FHH (r = 0.407 to 0.420; p < 0.0001). CONCLUSION: This study emphasized that the tridimensional PF geometry measurement in the corrected coronal plane of the femoral neck can be useful to determine and optimize the design of a non-modular cementless femoral stem. Particularly, continuous homothetic size progression of the intra- and extramedullary PF parameters should be achieved to assure stem fixation and restore anatomic hip biomechanics. PMID- 29468266 TI - Bilateral patterns and motor function of the extralaryngeal branching of the recurrent laryngeal nerve. AB - PURPOSE: To evaluate the bilateral patterns and motor function of the extralaryngeal branches (ELB) of the recurrent laryngeal nerve(RLN). METHODS: This study included 500 consecutive patients who underwent total thyroidectomy. Intraoperative nerve monitoring (IONM) was used in 230 patients. Demographic data, indications for surgery, the bilateral patterns of ELB of the RLN, electromyographic activity of the ELB, distance between the branching point to the entrance into the larynx, and the rate of postoperative morbidity were analyzed. RESULTS: The overall rate of ELB was 27.6% (276/1000). A single trunk of the RLN on both sides was found in 269 (54%) patients, whereas ELB on both sides was observed in 45 (9%) patients. The rates of ELB on the left and right sides were 26.6 and 28.6%, respectively. Of the 89 branched nerves which were dissected using IONM, an evoked motor response was present in 100% of the anterior branches and 5.6% of the posterior branches. The mean branching distance of the RLN was significantly greater in female patients than in male patients on the left side (p = 0.031). The patterns of ELB showed no significant difference in male and female patients. The rates of postoperative transient and permanent hypoparathyroidism and unilateral RLN palsy were 21.6 and 2.8%, and 3.2 and 0.8%, respectively. The rate of RLN palsy was higher in branched nerves compared to those with a single trunk (0.75 vs 0.3%; p = 0.2). CONCLUSION: Unilateral ELB of the RLN might be observed in approximately 1/4 of the patients, while bilateral branching is rare. A few number of posterior branches of the RLN can have motor function. The RLN's with ELB might have a higher risk of injury compared to those with a single trunk. PMID- 29468268 TI - ? PMID- 29468267 TI - A congenital accessory skin appendage of the nasal columella and nostril sill: a rare anatomical variation. AB - PURPOSE: An accessory skin appendage of the nasal columella and nostril sill is an extremely rare congenital anatomical malformation; only a single case has been reported in the literature. However, no pathophysiology has been proposed. The purpose of this study is to present a review of the anatomical distribution of accessory skin appendages and provide a comprehensive review of their pathophysiology based on embryological development. METHODS: We present four cases of a protruding skin appendage of the nasal columella or nostril sill. All lesions were present from birth with no family history of skin appendages. Three patients underwent surgical excision under local anesthesia. RESULTS: The lesions were located at the upper and lower lateral borders of the nasal columella and the medial and lateral borders of the nostril sill. There has been no sign of recurrence over a mean follow-up of 11 months. CONCLUSIONS: Any obstacle or injury during the migration process of embryonic development may result in maldevelopment. If an obstacle or injury occurs during the medial migration of the medial nasal process, congenital polypoid remnant tissue may remain along the migration route, resulting in an accessory skin appendage of the nasal columella. The location of the accessory columellas ranged from the nostril sill to the soft triangle along the anterior border of the medial crus of the alar cartilage. These anatomical distributions correspond exactly to the migration route of the medial nasal process during embryonic development. We believe that it supports our suggested pathophysiology. PMID- 29468269 TI - Race Differences in Gastrostomy Tube Placement After Stroke in Majority-White, Minority-Serving, and Racially Integrated US Hospitals. AB - We sought to determine individual and system contributions to race disparities in percutaneous endoscopic gastrostomy (PEG) tube placement after stroke. Ischemic stroke admissions were identified from the Nationwide Inpatient Sample between 2007 and 2011. Hospitals were categorized based on the percentage of ethnic/racial minority stroke patients (< 25% ethnic/racial minorities ["majority white hospitals"], 25-50% ethnic/racial minorities ["racially integrated hospitals"], or > 50% ethnic/racial minorities ["minority-serving hospitals"]). Logistic regression was used to evaluate the association between ethnicity/race and PEG utilization within and between the different hospital strata. Among 246,825 stroke admissions, patients receiving care in minority-serving hospitals had higher odds of PEG compared to patients in majority-white hospitals, regardless of individual patient race (adjusted odds ratio [OR] 1.24, 95% CI 1.12 1.38). Ethnic/racial minorities had higher odds of PEG than whites in any hospital strata; however, this discrepancy was largest in majority-white hospitals (OR 1.62, 95% CI 1.48-1.76), and smallest in minority-serving hospitals (OR 1.22, 95% CI 1.11-1.33; p for interaction < 0.001). Ethnic/racial minority patients had similar odds of PEG in any hospital strata, while white patients had increasing odds of PEG in racially integrated and minority-serving compared to majority-white hospitals (OR 1.28, 95% CI 1.15-1.43 in racially integrated, and OR 1.39, 95% CI 1.23-1.57 in minority-serving, compared to majority-white hospitals, p for trend < 0.001). The likelihood of PEG after ischemic stroke was increased in minority-serving compared to majority-white hospitals. White patients had higher odds of PEG in minority-serving compared to majority-white hospitals, indicating a systemic difference in PEG placement across hospitals. PMID- 29468270 TI - Unplanned readmission after hospital discharge in burn patients in Iran. AB - INTRODUCTION: Burns are considered as one of the most serious health problems throughout the world. They may lead to adverse consequences and outcomes. One of these outcomes is unplanned readmission. Unplanned readmission has been commonly used as a quality indicator by hospitals and governments. This study aimed to determine the predictors of unplanned readmission in patients with burns hospitalized in a burn center in the North of Iran (Guilan province, Rasht). METHODS: This retrospective analytic study has been done on the medical records of hospitalized patients with burns in Velayat Sub-Specialty Burn and Plastic Surgery Center, Rasht, Iran during 2008-2013. In general, 703 medical records have been reviewed but statistical analysis was performed on 626 medical records. All data were entered in SPSS (version 16) and analyzed by descriptive and inferential statistics. RESULTS: Among 626 patients with burns, the overall readmission rate was 5.1%. Predictors of readmission included total body surface area (OR 1.030, CI 1.011-1.049), hypertension (OR 2.923, CI 1.089-7.845) and skin graft (OR 7.045, CI 2.718-18.258). CONCLUSION: Considering the outcome, predictors following burn have a crucial role in the allocation of treatment cost for patients with burns and they can be used as one of the quality indicators for health care providers and governments.

PMID- 29468273 TI - Evolution, functional differentiation, and co-expression of the RLK gene family revealed in Jilin ginseng, Panax ginseng C.A. Meyer. AB - Most genes in a genome exist in the form of a gene family; therefore, it is necessary to have knowledge of how a gene family functions to comprehensively understand organismal biology. The receptor-like kinase (RLK)-encoding gene family is one of the most important gene families in plants. It plays important roles in biotic and abiotic stress tolerances, and growth and development. However, little is known about the functional differentiation and relationships among the gene members within a gene family in plants. This study has isolated 563 RLK genes (designated as PgRLK genes) expressed in Jilin ginseng (Panax ginseng C.A. Meyer), investigated their evolution, and deciphered their functional diversification and relationships. The PgRLK gene family is highly diverged and formed into eight types. The LRR type is the earliest and most prevalent, while only the Lec type originated after P. ginseng evolved. Furthermore, although the members of the PgRLK gene family all encode receptor like protein kinases and share conservative domains, they are functionally very diverse, participating in numerous biological processes. The expressions of different members of the PgRLK gene family are extremely variable within a tissue, at a developmental stage and in the same cultivar, but most of the genes tend to express correlatively, forming a co-expression network. These results not only provide a deeper and comprehensive understanding of the evolution, functional differentiation and correlation of a gene family in plants, but also an RLK genic resource useful for enhanced ginseng genetic improvement.

AB - This paper discusses otorhinolaryngological symptoms associated with functional disorders of the upper cervical spine. Hints aimed to avoid misdiagnoses of cross organ otorhinolaryngological symptoms as phobic or psychogenic disorders are presented. Clinically relevant neuroanatomical convergence of the upper cervical spine (occiput to C3) is fundamental for the interpretation of functional otorhinolaryngological symptoms. Based thereon, evidence for the most common cervical differential diagnoses of dizziness, tinnitus, dysphagia, and craniomandibular dysfunction is presented separately. The corresponding therapeutic options and their contraindications are discussed in the concluding chapter. The importance of interdisciplinary cooperation in related fields is emphasized. PMID- 29468275 TI - [The innate immune system in oropharyngeal squamous cell carcinoma : Immune modulation by HPV]. AB - Based on clinical and experimental data, oropharyngeal squamous cell carcinomas (OPSCC) associated with human papillomavirus (HPV) have been recognized as a distinct entity of head and neck cancers. However, outside of clinical trials, HPV status currently has no impact on treatment. The natural replication cycle of HPV takes place in epithelial cells, and is thus spatially separated from cytotoxic immune cells in the epidermis. Dendritic cells (Langerhans cells, LC), however, are frequent in this upper dermal layer. The ability of LC to process antigens, migrate, and, ultimately activate T cells is inhibited by the activity of the viral oncoproteins (E5-E7). Downregulation of functional human leukocyte antigen I (HLA-I) epithelial cell surface expression contributes to LC inhibition. However, due to their absence in upper skin layers, corresponding activation of natural killer (NK) cells via missing-self recognition is not relevant. Genome-wide analyses have revealed specific expression signatures for HPV-associated OPSCC that are distinct from HPV-negative cancers. Interestingly, aberrations in HLA-I genes were common in HPV-associated OPSCC. Our own findings indicate more frequent infiltration of HPV-associated OPSCC by CD56-positive (CD56+) NK cells, which might be related to HLA-I downregulation during HPV associated carcinogenesis. In patients with OPSCC, CD56 positivity correlates with improved prognosis after conventional therapy. This could be evidence for HPV-associated OPSCC being especially eligible for novel immune-based therapies and an indication that immunological data should be included in the design of clinical trials. PMID- 29468276 TI - Identification and assessment of frailty in older patients with chronic myeloid leukemia and myelofibrosis, and indications for tyrosine kinase inhibitor treatment. AB - The incidence of cancer, including myeloproliferative neoplasms (MPNs), is projected to increase significantly due to the growing proportion of people aged > 65 years. These older individuals are a heterogeneous population in terms of fitness, comorbidity, and psychological reserve. Therefore, age per se does not always provide an accurate indication of condition in patients with cancer. Frailty has been proposed as an alternative measure of vulnerability that might better indicate which patients can tolerate standard cancer treatment and those who may benefit from treatment adjustment. A number of methods can be used to assess frailty in older patients with hematological malignancies, including the Cardiovascular Health Study Frailty Screening Measure, the FRAIL (Fatigue, Resistance, Ambulation, Illnesses, and Loss of weight) questionnaire, the Clinical Frailty Scale (CFS), and the Gerontopole Frailty Screening Tool. In addition to physical frailty, comorbidity and quality of life should also be included in the assessment. Prior to the introduction of tyrosine kinase inhibitors (TKIs), age was considered a marker of poor prognosis in patients with MPNs. In contrast, data show that age is not necessarily a contraindication for TKI use. In CML, the efficacy of TKIs has been shown to be independent of age. The JAK1/2 inhibitor ruxolitinib also seems to be effective across a range of patient ages. Available data suggest that chronological age itself should not necessarily be a contraindication for many new therapies in patients with MPNs, and that frailty does provide a better measure of vulnerability. There is a need for specific methods to assess frailty in patients with MPNs, particularly the context of effective new treatment options, such as TKIs and ruxolitinib. PMID- 29468277 TI - [Tinea faciei caused by Nannizzia persicolor : An underdiagnosed dermatophyte?] AB - We report on a tinea faciei caused by Nannizzia (N.) persicolor. The 4-year-old boy had probably been infected by a guinea pig. Unambiguous infections caused by N. persicolor are rarely seen in Germany; however, this zoophilic and geophilic dermatophyte may only be rarely identified due to its resemblance to Trichophyton (T.) mentagrophytes. Therefore, the diagnostic attributes of N. persicolor and its differentiation from T. mentagrophytes are described. Particularly in case of contact with rodents, N. persicolor should be kept in mind. PMID- 29468278 TI - [Bullosis diabeticorum : Two case studies]. AB - We report two cases of patients with diabetes mellitus who developed bullae measuring 2 cm in diameter on the fingers or toes, which could be classified as bullosis diabeticorum after excluding several differential diagnoses that are discussed. Bullosis diabeticorum is a rare blister formation located on the palmoplantar region, which is mainly observed in the case of diabetic patients. The clinical picture is characterized by tense bullae measuring up to 10 cm in diameter, containing clear to hemorrhagic fluid. Generally, lesions heal without residual scarring, less frequently with residual postinflammatory pigmentation or tender scars. On histopathological examination, both intraepidermal and subepidermal bullae are found without any significant inflammatory infiltrate. The etiopathogenesis of bullosis diabeticorum has not yet been clarified. PMID- 29468279 TI - [Epidemiology of penile cancer]. AB - BACKGROUND: Penile cancer represents a rarity in daily clinical practice. OBJECTIVES: The aim is to identify global differences concerning the incidence, social and risk factors. METHODS: The past and current epidemiologic literature is analyzed concerning incidence rates and risk factors. The latter are discussed concerning their potential with regard to disease prevention. RESULTS: Globally, incidence rates of penile cancer range from low to nonexistent. Distinct differences are found when comparing industrialized countries with emerging and developing countries. Phimosis seems to be a crucial risk factor in the formation of penile cancer. Additionally, chronic inflammatory diseases of the penis were found to be associated with a higher risk. CONCLUSIONS: Preventive measures should be considered in relation to the rarity of the disease, especially in the valuation of circumcision during early childhood. Regular clinical examination of the penis is a sensible measure of early detection. PMID- 29468280 TI - [Pathology and histopathological evaluation of penile cancer]. AB - BACKGROUND: Penile cancer is rare in Germany and in western European countries. Our understanding of the pathogenesis and pathology of this malignancy has increased considerably in recent years. OBJECTIVES: Clinical management has become more complex, with organ-preserving strategies being increasingly favored. Associated with these developments, the demands on the pathology reports of biopsies and surgical specimens from the penis have also increased. MATERIALS AND METHODS: According to guidelines and the relevant literature, this review outlines the most important aspects that must be considered in the classification and pathological reporting of penile cancer. RESULTS: Correct histological subtyping of penile cancer is important for prognostic and therapeutic considerations. There are also some peculiarities with the current TNM classification system of this tumor compared to other entities. CONCLUSION: Handling of specimens and histopathological typing must be performed by experienced pathologists according to recent developments in the pathogenesis, classification, and therapeutic strategies of penile cancer. PMID- 29468281 TI - [Current guideline-oriented follow-up of small renal masses : Applied risk scores and future outlook]. AB - After surgical resection of renal cell carcinoma by laparoscopic or open partial or complete nephrectomy, medical aftercare based on the current guidelines should be provided. This seems desirable, especially because one third of patients after initial curative tumor resection develop recurrence over time. In this article, the current recommendations for follow-up will be systematically presented based on the accepted German S3 guideline and the European Association of Urology (EAU) guideline. Another point of this article will be the presentation of the currently applied risk scores to predict prognosis with a focus on molecular markers. The goal is to improve the prediction of survival and to facilitate risk adjusted aftercare. PMID- 29468282 TI - [Standard surgery for small renal masses (<4 cm)]. AB - BACKGROUND: Several new treatment strategies have emerged in the treatment of small renal masses (<4 cm in diameter). Active surveillance and ablative techniques have been introduced but it remains unclear which patients will benefit the most from these new treatment options. A surgical approach remains standard of care. In recent decades, radical nephrectomy has been replaced by nephron-sparing surgery for the management of small renal masses. RESULTS: In addition to the open partial nephrectomy, which is considered the standard approach, the number of surgeries performed using minimally invasive techniques is increasing. Recent data show that there might be some benefits such as less blood loss. The disadvantages shown by laparoscopic partial nephrectomy such as prolonged warm ischemia, longer operation times, and postoperative renal impairment might be negligible for the robotic approach. Therefore, current guidelines allow these approaches in addition to open partial nephrectomy if sufficient surgical expertise is given. PMID- 29468283 TI - Activation of Wnt/beta-catenin signaling is involved in hair growth-promoting effect of 655-nm red light and LED in in vitro culture model. AB - Activation of the Wnt/beta-catenin signaling pathway plays an important role in hair follicle morphogenesis and hair growth. Recently, low-level laser therapy (LLLT) was evaluated for stimulating hair growth in numerous clinical studies, in which 655-nm red light was found to be most effective and practical for stimulating hair growth. We evaluated whether 655-nm red light + light-emitting diode (LED) could promote human hair growth by activating Wnt/beta-catenin signaling. An in vitro culture of human hair follicles (HFs) was irradiated with different intensities of 655-nm red light + LED, 21 h7 (an inhibitor of beta catenin), or both. Immunofluorescence staining was performed to assess the expression of beta-catenin, GSK3beta, p-GSK3beta, and Lef1 in the Wnt/beta catenin signaling. The 655-nm red light + LED not only enhanced hair shaft elongation, but also reduced catagen transition in human hair follicle organ culture, with the greatest effectiveness observed at 5 min (0.839 J/cm2). Additionally, 655-nm red light + LED enhanced the expression of beta-catenin, p GSK3beta, and Lef1, signaling molecules of the Wnt/beta-catenin pathway, in the hair matrix. Activation of Wnt/beta-catenin signaling is involved in hair growth promoting effect of 655-nm red light and LED in vitro and therefore may serve as an alternative therapeutic option for alopecia. PMID- 29468284 TI - Is neutrophil-to-lymphocytes ratio a clinical relevant preoperative biomarker in upper tract urothelial carcinoma? A meta-analysis of 4385 patients. AB - BACKGROUND: Preoperative blood-based inflammatory biomarkers have been suggested to improve staging and prognostication in patients with upper-tract urothelial carcinoma (UTUC). Neutrophil-to-lymphocyte ratio (NLR) is the most studied blood based biomarker. NLR is an indicator of systemic inflammation and has been shown to be associated with a poor prognosis in various malignancies. The aim of this study was to analyze the current evidence regarding the prognostic significance of preoperative NLR in patients undergoing radical nephroureterectomy (RNU) for UTUC to assess its prognostic potential. MATERIALS AND METHODS: A systematic search of Web of Science, Medline/PubMed and Cochrane library was performed on the 1st of October, 2017. Studies were deemed eligible if they compared patients with high NLR before surgical treatment for UTUC to patients with low NLR to determine its predictive value for survival using multivariable logistic regression analysis. We performed a formal meta-analysis for cancer-specific survival (CSS), recurrence-free survival (RFS) and overall survival (OS). RESULTS: Nine studies including a total of 4385 patients assessing the importance of NLR were included in this meta-analysis. The cut-off NLR varied in the eligible studies ranging from 2 to 3. Increased pretreatment NLR predicted OS (pooled HR 1.64 95% CI; 1.23-2.17), RFS (pooled HR 1.60 95% CI; 1.16-2.20) and CSS (pooled HR 1.73 95% CI; 1.23-2.44) in multivariable analyses. CONCLUSION: In this meta-analysis, preoperative blood-based NLR is associated with worse prognosis in patients who underwent RNU for UTUC. NLR could be used to improve clinical decision making regarding RNU vs. kidney-sparing surgery, extent of lymphadenectomy, perioperative systemic therapy and follow-up schedule. PMID- 29468285 TI - Thirty years of great ape gestures. AB - We and our colleagues have been doing studies of great ape gestural communication for more than 30 years. Here we attempt to spell out what we have learned. Some aspects of the process have been reliably established by multiple researchers, for example, its intentional structure and its sensitivity to the attentional state of the recipient. Other aspects are more controversial. We argue here that it is a mistake to assimilate great ape gestures to the species-typical displays of other mammals by claiming that they are fixed action patterns, as there are many differences, including the use of attention-getters. It is also a mistake, we argue, to assimilate great ape gestures to human gestures by claiming that they are used referentially and declaratively in a human-like manner, as apes' "pointing" gesture has many limitations and they do not gesture iconically. Great ape gestures constitute a unique form of primate communication with their own unique qualities. PMID- 29468286 TI - Fibrolamellar Hepatocellular Carcinoma: Treatment with Yttrium-90 and Subsequent Surgical Resection. AB - We describe a 52-year-old female patient who presented with a 9.5-cm fibrolamellar hepatocellular carcinoma (FL-HCC). The patient was initially unsuitable for surgical resection and therefore underwent transarterial chemoembolization followed by selective internal radiation therapy (SIRT) with Yttrium-90 to downsize the tumour. Following SIRT, the tumour decreased in volume from 350 to 20 cm3 allowing curative (R0) resection with an extended left hepatectomy and reconstruction of IVC. This is the first reported case of FL-HCC treated with SIRT in which, due to the good SIRT response, the patient was downsized to allow curative resection. PMID- 29468287 TI - Pickering-Emulsion for Liver Trans-Arterial Chemo-Embolization with Oxaliplatin. AB - PURPOSE: Biodegradable polylactic-co-glycolic acid (PLGA) nanoparticles can adsorb at the water/oil interface to stabilize the emulsion (forming Pickering emulsion). The purpose of this study was to compare the release profiles of oxaliplatin from Pickering-emulsion and Lipiodol-emulsion. MATERIALS/METHODS: Pickering-emulsions and Lipiodol-emulsions were both formulated with oxaliplatin (5 mg/mL) and Lipiodol (water/oil ratio: 1/3). For Pickering-emulsion only, PLGA nanoparticles (15 mg/mL) were dissolved into oxaliplatin before formulation. In vitro release of oxaliplatin from both emulsions was evaluated. Then, oxaliplatin was selectively injected into left hepatic arteries of 18 rabbits bearing VX2 liver tumors using either 0.5 mL Pickering-emulsion (n = 10) or 0.5 mL Lipiodol emulsion (n = 8). In each group, half of the rabbits were killed at 1 h and half at 24 h. Mass spectrometry was used to quantify drug pharmacokinetics in blood and resulting tissue (tumors, right, and left livers) oxaliplatin concentrations. RESULTS: Pickering-emulsion demonstrated a slow oxaliplatin release compared to Lipiodol-emulsion (1.5 +/- 0.2 vs. 12.0 +/- 6% at 1 h and 15.8 +/- 3.0 vs. 85.3 +/- 3.3% at 24 h) during in vitro comparison studies. For animal model studies, the plasmatic peak (Cmax) and the area under the curve (AUC) were significantly lower with Pickering-emulsion compared to Lipiodol-emulsion (Cmax = 0.49 +/- 0.14 vs. 1.08 +/- 0.41 ng/mL, p = 0.01 and AUC = 19.8 +/- 5.9 vs. 31.8 +/- 14.9, p = 0.03). This resulted in significantly lower oxaliplatin concentrations in tissues at 1 h with Pickering-emulsion but higher ratio between tumor and left liver at 24 h (43.4 vs. 14.5, p = 0.04). CONCLUSION: Slow release of oxaliplatin from Pickering-emulsion results in a significant decrease in systemic drug exposure and higher ratio between tumor and left liver oxaliplatin concentration at 24 h. PMID- 29468288 TI - Efficacy of Mechanical Thrombectomy Using Stent Retriever and Balloon-Guiding Catheter. AB - PURPOSE: Intra-arterial therapy of acute ischemic stroke has developed rapidly in recent years. Due to proven efficacy in randomized trials, stent retrievers were replacing first-generation thrombectomy devices and have been defined as method of choice. However, aspiration catheters or a combination of several techniques have shown promising rates of successful recanalizations. To create a basis for comparison of the new approaches according to real-world data, we determined the first pass recanalization rate of an evidence-based standard technique with the use of a stent retriever in combination with a balloon-guiding catheter. The assessment was based on the number of required passages and reperfusion rate, but not on clinical results. METHODS: Patients from our institution with anterior circulation occlusions and mechanical thrombectomy by using stent retrievers in combination with balloon-guiding catheters were analyzed retrospectively. Reperfusion was graded with the "thrombolysis in cerebral infarction" (TICI) classification on post-interventional angiograms. Additionally, the number of passes and the duration of the recanalization procedure were recorded. RESULTS: Between 2014 and July 2017, 201 patients met the inclusion criteria. Successful recanalization, defined as a TICI scale 2b/3, was 91% (TICI 2b was achieved in 44% and TICI 3 in 47%) after the procedure. After the first passage, successful recanalization was achieved in 65% of the patients. Mean number of passes was 1.4 (1-5 passes) for all patients. Median duration of the procedure was 49 min (0:11 2:35 h). CONCLUSIONS: Even a standard thrombectomy technique with the use of a stent retriever together with a balloon-guiding catheter provides reasonable recanalization rates with only one passage. The results can be taken as benchmark for alternative and more complex techniques. PMID- 29468289 TI - Effect of Cryopreservation on Enzyme and Transporter Activities in Suspended and Sandwich Cultured Rat Hepatocytes. AB - Freshly-isolated rat hepatocytes are commonly used as tools for hepatic drug disposition. From an ethical point of view, it is important to maximize the use of isolated hepatocytes by cryopreservation. The present study compared overall hepatocyte functionality as well as activity of the organic anion transporting polypeptide (Oatp), multidrug resistance-associated protein 2 (Mrp2), and UDP glucuronosyltransferase 1 (Ugt1), in in vitro models established with cryopreserved and freshly-isolated hepatocytes. A similar culture time-dependent decline in cellular functionality, as assessed by urea production, was observed in sandwich-cultured hepatocytes (SCH) obtained from freshly-isolated and cryopreserved cells. Concentration-dependent uptake kinetics of the Oatp substrate sodium fluorescein in suspended hepatocytes (SH) or SCH were not significantly affected by cryopreservation. Mrp2-mediated biliary excretion of 5 (and 6)-carboxy-2',7'-dichlorofluorescein by SCH was assessed with semi quantitative fluorescence imaging: biliary excretion index values increased between day 3 and day 4, but did not differ significantly between cryopreserved and freshly-isolated hepatocytes. Finally, telmisartan disposition was evaluated in SCH to simultaneously explore Oatp, Ugt1, and Mrp2 activity. In order to distinguish between the susceptibilities of the individual disposition pathways to cryopreservation, a mechanistic cellular disposition model was developed. Basolateral and canalicular efflux as well as glucuronidation of telmisartan were affected by cryopreservation. In contrast, the disposition parameters of telmisartan-glucuronide were not impacted by cryopreservation. Overall, the relative contribution of the rate-determining processes (uptake, metabolism, efflux) remained unaltered between cryopreserved and freshly-isolated hepatocytes, indicating that cryopreserved hepatocytes are a suitable alternative for freshly-isolated hepatocytes when studying these cellular disposition pathways. PMID- 29468290 TI - [Early undifferentiated arthritis]. AB - Early recognition and treatment of inflammatory arthritis is imperative for the further course of the disease. Patients with inflammatory arthritis should be referred as early as possible to a rheumatologist for further management. A combination of anamnesis, clinical examination, imaging and laboratory measurements enable a differential diagnosis. If a specific diagnosis is not possible, the disease is called early undifferentiated arthritis. Early effective treatment should be instituted for those at risk of developing persistent and/or erosive arthritis. Treatment includes both pharmacological and non pharmacological options. In the management of early arthritis a combination of regular monitoring and optimal treatment interventions are paramount to achieve remission and improve outcome of the disease (treat-to-target). PMID- 29468291 TI - Lymphangiomatosis: a rare entity presenting with involvement of the sacral plexus. AB - Lymphangiomatosis is an uncommon disease process characterized by multisystem lymphatic malformations that can involve numerous body systems, including organs, muscles, soft tissues, and bones. Involvement of the nervous system is rare and has even been previously described as a site of sparing. We present a case of a 24-year-old female with known lymphangiomatosis, presenting with acute onset of lower extremity paresthesias, weakness, and new urinary retention. MRI of the pelvis revealed lymphangiomatosis of the sacral plexus, which has not been previously reported. We will review the clinical and imaging manifestations of lymphangiomatosis and provide a differential diagnosis for masses of the lumbosacral plexus. Although lower extremity pain and weakness encountered in the emergency department or outpatient setting is most frequently caused by lumbar spine pathology, occasionally, abnormalities of the lumbosacral plexus may prove to be the cause. While peripheral nerve sheath tumors lead the differential diagnosis of tumor or tumor-like entities involving the lumbosacral plexus, lymphangiomatosis is a rare differential consideration. PMID- 29468292 TI - Compact devices for generation of reference trace VOC mixtures: a new concept in assuring quality at chemical and biochemical laboratories. AB - Volatile organic compounds (VOCs) in gas mixtures at trace level (nmol/mol) are routinely measured by chemical and biochemical laboratories as climate indicators, indoor air quality pollutants from building materials emissions, contaminants in food and beverages, and biomarkers in body fluids (blood, urine, breath) of occupational exposure or human diseases. Current analytical instruments used for measurements are gas chromatographs equipped with various injector and detector configurations. The assurance of measurement quality is done by using a huge amount of certified liquid VOC standard solutions (or gaseous VOC standard cylinders) with multiple dilutions to reach the required trace level. This causes high standard uncertainty in instrument calibrations, high cost, and high consumption of analysis and laboratory personal time. In this paper, we present the implementation of portable generators producing VOC gas standards at trace level for automatic and direct calibration of VOC detectors employed in various contexts, removing the need for preparation of matrix calibration standards in cylinders. Two compact devices in-house developed by two national metrology institutes-the Istituto Nazionale di Ricerca Metrologica (INRIM) and the Federal Institute of Metrology (METAS)-are here used to dynamically generate reference gas mixtures in an SI traceable way. The two devices are based on different technologies: diffusion and permeation, for INRIM and METAS, respectively. A metrological characterization is given and the practical implementation at chemical and biochemical laboratories is discussed.

AB - A novel ionic liquid (IL)-based microextraction method has been developed for the determination of four hydroxylated polycyclic aromatic hydrocarbons (OHPAHs) in urine samples. The water soluble IL-based surfactant selected as extraction solvent is decylguanidinium chloride (C10Gu-Cl), the cytotoxicity and micellar behavior of which were evaluated. The proposed salt-induced IL-based preconcentration method simply consists in adding NaClO4 to the aqueous medium containing the IL to promote its water insolubility. The entire method was optimized, requiring the use of only 20 MUL of C10Gu-Cl for 10 mL of diluted urine sample (1:10) without any pH adjustment, followed by the addition of NaClO4 to ensure a 5% (w/v) content. A cloudy solution was observed immediately, and after the application of 4 min of vortex and 8 min of centrifugation, the droplet was diluted up to 60 MUL with a mixture of acetonitrile:water (30:70) and injected into the liquid chromatograph with fluorescence detection. The method was validated using both synthetic urine and human urine as matrix for the determination of the four OHPAHs. The following analytical features were obtained: detection limits down to 1 ng.L-1 in real urine; inter-day reproducibility (as RSD in %) always lower than 17% when dealing with real urine samples spiked at 80 ng.L-1; and average relative recoveries of 102% in real urine samples at such low spiked levels. Despite the simplicity of the proposed method, it performed successfully with complex urine samples.

PMID- 29468294 TI - Behavioral phenotyping and dopamine dynamics in mice with conditional deletion of the glutamate transporter GLT-1 in neurons: resistance to the acute locomotor effects of amphetamine. AB - RATIONALE: GLT-1 is the major glutamate transporter in the brain and is expressed predominantly in astrocytes but is also present in excitatory axon terminals. To understand the functional significance of GLT-1 expressed in neurons, we generated a conditional GLT-1 knockout mouse and inactivated GLT-1 in neurons using Cre-recombinase expressed under the synapsin 1 promoter, (synGLT-1 KO). OBJECTIVES: Abnormalities of glutamate homeostasis have been shown to affect hippocampal-related behaviors including learning and memory as well as responses to drugs of abuse. Here, we asked whether deletion of GLT-1 specifically from neurons would affect behaviors that assessed locomotor activity, cognitive function, sensorimotor gating, social interaction, as well as amphetamine stimulated locomotor activity. METHODS/RESULTS: We found that the neuronal GLT-1 KO mice performed similarly to littermate controls in the behavioral tests we studied. Although performance in open field testing was normal, the acute locomotor response to amphetamine was significantly blunted in the synGLT-1 KO (40% of control). We found no change in amphetamine-stimulated extracellular dopamine in the medial shell of the nucleus accumbens, no change in electrically stimulated or amphetamine-induced dopamine release, and no change in dopamine tissue content. CONCLUSIONS: These results support the view that GLT-1 expression in neurons is required for amphetamine-induced behavioral activation, and suggest that this phenotype is not produced through a change in dopamine uptake or release. Although GLT-1 is highly expressed in neurons in the CA3 region of the hippocampus, the tests used in this study were not able to detect a behavioral phenotype referable to hippocampal dysfunction.

AB - BACKGROUND: In cases of rare cancer entities, such as malignant melanoma of the conjunctiva, there are often no evidence-based national guidelines available. Standard operating procedures (SOP) are an alternative in these cases. OBJECTIVE: The aim of this project was to develop a consensus SOP for diagnosis, treatment, and follow-up care of conjunctival melanomas between the 14 Centers of Excellence in Germany supported by German Cancer Aid. METHODS: The SOP was prepared according to a defined process including timelines, flow of information, and roles.

PMID- 29468296 TI - [Corneal densitometry : Value for keratoconus diagnostics]. AB - BACKGROUND: Corneal densitometry, based on the Scheimpflug principle, is a useful noninvasive tool for quantitative evaluation of the optical quality of the cornea. It enables us to evaluate corneal transparency in the different corneal layers and different annuli. In this article, we discuss the basis of application of corneal densitometry measurements and summarize findings in patients with keratoconus. METHODS: This article is based on a selective literature review and analysis of own data. RESULTS: Patients with keratoconus have significant higher corneal densitometry values compared to healthy controls. Densitometry values also correlate with the extent of the disease. In the first months after corneal cross-linking (CXL), haze formation occurs and leads to a decrease in corneal transparency, thus densitometry peaks. Long-term analysis of densitometric data have shown that corneal transparency then starts to decrease after 3 to 6 months, and improves further with time. At 24 to 36 months after CXL, corneal transparency levels might achieve physiological values. CONCLUSION: Corneal transparency is reduced in patients with keratoconus. In the first months after CXL, haze formation and a reduction in corneal transparency can be observed, which subsequently improve with time. PMID- 29468297 TI - Aldopentoses as new substrates for the membrane-bound, pyrroloquinoline quinone dependent glycerol (polyol) dehydrogenase of Gluconobacter sp. AB - Membrane-bound, pyrroloquinoline quinone (PQQ)-dependent glycerol dehydrogenase (GLDH, or polyol dehydrogenase) of Gluconobacter sp. oxidizes various secondary alcohols to produce the corresponding ketones, such as oxidation of D-sorbitol to L-sorbose in vitamin C production. Substrate specificity of GLDH is considered limited to secondary alcohols in the D-erythro configuration at the next to the last carbon. Here, we suggest that L-ribose, D- and L-lyxoses, and L-tagatose are also substrates of GLDH, but these sugars do not meet the substrate specificity rule of GLDH. The oxygen consumption activity of wild-type Gluconobacter frateurii cell membranes depends on several kinds of sugars as compared with that of the membranes of a GLDH-negative variant. Biotransformation of those sugars with the membranes was examined to determine the reaction products. A time course measuring the pH in the reaction mixture and the increase or decrease in substrates and products on TLC suggested that oxidation products of L-lyxose and L-tagatose were ketones with unknown structures, but those of L-ribose and D lyxose were acids. The oxidation product of L-ribose was purified and revealed to be L-ribonate by HRMS and NMR analysis. Biotransformation of L-ribose with the membranes and also with the whole cells produced L-ribonate in nearly stoichiometric amounts, indicating that the specific oxidation site in L-ribose is recognized by GLDH. Since purified GLDH produced L-ribonate without any intermediate-like compounds, we propose here a reaction model where the first carbon in the pyranose form of L-ribose is oxidized by GLDH to L-ribonolactone, which is further hydrolyzed spontaneously to produce L-ribonate. PMID- 29468298 TI - Endoscopy, histology and electron microscopy analysis of foetal membranes in pregnant South American plains vizcacha reveal unusual excrescences on the yolk sac. AB - The South American hystricognathe Lagostomus maximus is a fossorial rodent whose females show unique reproductive characteristics. They have a 155-day long gestation, show massive polyovulation and a selective process of embryonic resorption in the first half of gestation. In order to explore and perform an in situ characterization of the reproductive tract, we visualized internal structures through ultrasonography and video-endoscopy in pregnant and non pregnant females. We describe the finding of protruding structures that lie on the yolk sac and their histological and ultrastructural characterization. The placenta was covered with whitish, small pearl-shaped structures. These structures were also seen on the extra-embryonic space, being the amnion and the umbilical cord free of them. Pearl-shaped structures were composed with loose connective tissue, lacked blood vessels, and showed collagen fibers organized in a spiral form. They were anchored by pedicles to the villous surface of the extraembryonic membrane. We discuss the biological and evolutionary meaning of the pearl-shaped structures that relate L. maximus to the African origin of the South American hystricognathe fauna. PMID- 29468299 TI - Smad4 and epithelial-mesenchymal transition proteins in colorectal carcinoma: an immunohistochemical study. AB - Epithelial-mesenchymal transition (EMT) plays an important role in cancer metastasis. During EMT, tumor cells acquire the capacity to migrate and invade the stroma. Activation of the transforming growth factor-b (TGF-b) signaling pathway is of major importance for the initiation of EMT. Smad4, an essential protein of this pathway, is known to complex with multiple transcription factors (e.g. Snail-1, Slug, Twist-1), in various types of cancer, promoting the repression or activation of target genes. The role of Smad4 in colorectal cancer (CRC) is not straightforward so far. In the present study forty eight resected CRC tumor specimens were immunohistochemically examined in order to assess the expression of Smad4 and its association with E-cadherin, Snail-1, Slug, Twist-1 protein expression and with various pathological parameters. Smad4 was found to be positively correlated with Snail-1, Slug and Twist-1 expression (p < 0.001). On the other hand it was negatively correlated with the expression of E-cadherin (p < 0.001). Furthermore, lymphatic invasion could be clearly associated with Smad4 expression, a finding complying with the metastatic ability of EMT cells. In conclusion, Smad4 could be considered as a central component of EMT transition in human colorectal cancer that combines with transcriptional factors to reduce E cadherin and alter the expression of the epithelial phenotype.

AB - In a typical cell division, chromosomes align at the metaphase plate before anaphase commences. This is not the case in Mesostoma spermatocytes. Throughout prometaphase, the three bivalents persistently oscillate towards and away from either pole, at average speeds of 5-6 MUm/min, without ever aligning at a metaphase plate. In our experiments, nocodazole (NOC) was added to prometaphase spermatocytes to depolymerize the microtubules. Traditional theories state that microtubules are the producers of force in the spindle, either by tubulin depolymerizing at the kinetochore (PacMan) or at the pole (Flux). Accordingly, if microtubules are quickly depolymerized, the chromosomes should arrest at the metaphase plate and not move. However, in 57/59 cells, at least one chromosome moved to a pole after NOC treatment, and in 52 of these cells, all three bivalents moved to the same pole. Thus, the movements are not random to one pole or other. After treatment with NOC, chromosome movement followed a consistent pattern. Bivalents stretched out towards both poles, paused, detached at one pole, and then the detached kinetochores quickly moved towards the other pole, reaching initial speeds up to more than 200 MUm/min, much greater than anything previously recorded in this cell. As the NOC concentration increased, the average speeds increased and the microtubules disappeared faster. As the kinetochores approached the pole, they slowed down and eventually stopped. Similar results were obtained with colcemid treatment. Confocal immunofluorescence microscopy confirms that microtubules are not associated with moving chromosomes. Thus, these rapid chromosome movements may be due to non-microtubule spindle components such as actin-myosin or the spindle matrix.

AB - Methods for rapid detection of fecal indicator bacteria in water are important to ensure that water is safe for drinking, bathing, recreation, fishing and shellfish harvesting. In this study, we tested experimental conditions for bacterial hydrolysis of two promising enzymatic substrates, 5-Bromo-4-chloro-3 indolyl beta-D-glucuronide (X-Gluc) and Resorufin beta-D-glucuronide (REG), and optimized parameters such as temperature and pH to determine conditions for rapid reactions. We then innovated a membrane filter-based approach to facilitate more rapid enzyme-based detection of Escherichia coli in water based on the combination of an initial concentration step and optimized test conditions. For this approach, a water sample (10-100 mL) is filtered through a 0.45-um pore size filter with a diameter of 4 or 13 mm. After filtration, a newly designed rapid detection broth is added containing the enzymatic inducer Methyl-beta-D Glucuronide sodium (MetGlu) and the substrate REG or X-Gluc. After a few (1-7) hours of incubation at 35 degrees C, the filter shows pink color (for REG containing broth) or green color (for X-Gluc containing broth) if E. coli is present. The study provides insights and approaches towards developing a simple, fast, and low-cost method to detect fecal indicator bacteria in water. PMID- 29468302 TI - Identification of Major Enzymes Involved in the Synthesis of Diadenosine Tetraphosphate and/or Adenosine Tetraphosphate in Myxococcus xanthus. AB - Myxococcus xanthus generates diadenosine tetraphosphates (Ap4A) and diadenosine pentaphosphates (Ap5A) under various stress conditions. M. xanthus lysyl-tRNA synthetase (LysS) efficiently synthesizes Ap4A from ATP, Ap5A from ATP and adenosine tetraphosphate (Ap4), and Ap4 from ATP and triphosphate. To identify other M. xanthus enzymes that can catalyze Ap4A and Ap4 synthesis, 15 M. xanthus aminoacyl-tRNA synthetases (aaRSs), four acyl-CoA synthetases (Acys), three acetyl-CoA synthetases (Aces), phosphoglycerate kinase (Pgk), and adenylate kinase (Adk) were expressed in Escherichia coli and examined for Ap4A or Ap4 synthetase activity using ATP or ATP and triphosphate as substrates. Among the tested enzymes, LysS had the highest Ap4A synthetase activity. AlaRS, SerRS, and LeuRS1 showed high ADP synthetase activity with ATP as a substrate in the presence of pyrophosphatase, and also demonstrated the ability to produce Ap4 from ATP and triphosphate in the absence of pyrophosphatase. Ap4 formation by AlaRS, SerRS, and LeuRS1 was approximately 4- to 13-fold higher compared with that of Ap4A, suggesting that these enzymes prefer triphosphate over ATP as a substrate in the second reaction. Some of the recombinant M. xanthus Acys and Aces also synthesized Ap4 from ATP and triphosphate. However, Pgk was capable of catalyzing the production of Ap4 from ATP and 3-phosphoglycerate in the presence of Mg2+ and did not require triphosphate, suggesting that this enzyme is mainly responsible for Ap4 synthesis in M. xanthus. PMID- 29468303 TI - The Extracellular Polymeric Substances of Legionella pneumophila Biofilms Contain Amyloid Structures. AB - Human infection by bacteria of the genus Legionella most often result in the pneumonia known as Legionnaires Disease. Legionella is found as a resident of adherent biofilms in man-made water systems. Disinfection efforts to prevent Legionella infections require a better understanding of the structures that promote Legionella surface attachment and biofilm colonization. Various enzymatic treatments, including multiple carbohydrate-targeting mixtures, failed to disrupt Legionella biofilms, despite the presence of carbohydrates in the biofilms as shown by biochemical methods and concanavalin-A lectin staining. Moreover, Legionella biofilms contained amyloids as detected by three microscopic staining methods (congo red, thioflavin T, and the amyloid-specific antibody WO2). Amyloid structures were seen in biofilms of both L. pneumophila and L. longbeachae, the two Legionella species most associated with human infection. Inhibition of amyloid assembly by congo red and thioflavin T limited both self-aggregation and surface attachment of L. pneumophila, indicating that functional amyloid structures have a key role in initial biofilm formation by these pathogenic bacteria. PMID- 29468304 TI - Genetic Analysis of the Listeria Pathogenicity Island 1 of Listeria monocytogenes 1/2a and 4b Isolates. AB - The aim of the present study was to apply descriptive, phylogenetic, recombination, and selection analyses on alignments of the Listeria Pathogenicity Island 1 (LIPI-1) of 1/2a and 4b Listeria monocytogenes isolates of different origin in order to gain insights into the evolution of this virulence gene cluster. For that purpose, a total of 19 L. monocytogenes isolates (9 meat isolates, serotype 1/2a; 5 meat isolates, serotype 4b; 5 strawberry isolates, serotype 4b) that have been previously separated at strain level were subjected to sequencing of their LIPI-1. Descriptive analysis revealed extensive nucleotide diversity mostly in the intragenic regions. The actA gene of 1/2a and 4b meat isolates and the hly gene of the 4b strawberry isolates exhibited the higher diversity; limited diversity was observed in prfA and plcA genes of the 4b isolates and mpl gene of the 1/2a isolates. Phylogenetic analysis of the complete island resulted in two major clusters that were consistent with serotype assignment of the isolates. Moreover, effective discrimination between serotypes was obtained by plcA, plcB, mpl, actA and the intergenic regions plcA-prfA and plcA-hly. In all cases but plcB and plcA-prfA 4b isolates were also differentiated according to their source of isolation as well. Selection analysis revealed that the island consisted of randomly evolving DNA with the exception of prfA gene of 1/2a isolates and actA gene of 4b meat isolates for which purifying selection or population expansion was indicated. Finally, no statistically significant evidence for recombination has been observed. PMID- 29468305 TI - Transovarian Transmission of Blochmannia and Wolbachia Endosymbionts in the Neotropical Weaver Ant Camponotus textor (Hymenoptera, Formicidae). AB - Camponotus is a hyper-diverse ant genus that is associated with the obligate endosymbiont Blochmannia, and often also with Wolbachia, but morphological studies on the location of these bacteria in the queen's ovaries during oogenesis remain limited. In the present study, we used the Neotropical weaver ant Camponotus textor to characterize the ovary using histology (HE) techniques, and to document the location of Blochmannia and Wolbachia during oogenesis through fluorescence in situ hybridization (FISH). This is the first morphological report of these two bacteria in the same host with polytrophic meroistic ovaries and reveals that Blochmannia is found inside late-stage oocytes and Wolbachia is associated with the nuclei of the nurse cells. Our results provide insights into the developmental sequence of when these bacteria reach the egg, with Blochmannia establishing itself in the egg first, and Wolbachia only reaching the egg shortly before completing egg development. Studies such as this provide understanding about the mechanisms and timing of the establishment of these endosymbionts in the host. PMID- 29468306 TI - Paratesticular alveolar rhabdomyosarcomas do not harbor typical translocations: a distinct entity with favorable prognosis? AB - The alveolar subtype of rhabdomyosarcoma (RMA) is a strong risk factor. Cases of RMA located in paratesticular sites have however been reported to have similar outcomes to those of embryonal rhabdomyosarcoma (RME). We wanted to re-evaluate the impact of subtype in paratesticular rhabdomyosarcoma (PT-RMS). Patients from a population-based cohort diagnosed with paratesticular RMA in 1990-2013 were analyzed. All tumor samples were re-reviewed using conventional morphology, immunohistochemistry, and molecular testing. Seven patients were eligible. Four tumors showed focal areas morphologically compatible with RMA (mixed RMA/RME). One case was undifferentiated, with a solid round-cell morphology which had to be reclassified as poorly differentiated RME. Two cases had a "microalveolar" morphology which is today regarded as sclerosing RME. No tumor showed the characteristic gene fusion of RMA. Five children had localized disease, one bone metastases, and another lymph-node involvement. All primaries were grossly resected. One locoregional relapse occurred. At a median follow-up of 7 years, all patients were alive disease-free. PT-RMS can show a focal alveolar histology combined with typical features of RME. In current morphological classifications, all rhabdomyosarcomas qualify for the alveolar subtype if typical features of RMA are realized at least focally. Rhabdomyosarcomas consisting of pure RMA morphology were however not found in our patients with PT-RMS. The mixed RMA/RMEs identified in our population-based study did not show a translocation typical for RMA and had a good prognosis. Further prospective studies need to evaluate if mixed RMA/RMEs have a similar favorable outcome in non-paratesticular sites as well. PMID- 29468307 TI - Understanding the antimicrobial properties/activity of an 11-residue Lys homopeptide by alanine and proline scan. AB - Previous work demonstrated that lysine homopeptides adopt a polyproline II (PPII) structure. Lysine homopeptides with odd number of residues, especially with 11 residues (K11), were capable of inhibiting the growth of a broader spectrum of bacteria than those with an even number. Confocal studies also determined that K11 was able to localize exclusively in the bacterial membrane, leading to cell death. In this work, the mechanism of action of this peptide was further analyzed focused on examining the structural changes in bacterial membrane induced by K11, and in K11 itself when interacting with bacterial membrane lipids. Moreover, alanine and proline scans were performed for K11 to identify relevant positions in structure conformation and antibacterial activity. To do so, circular dichroism spectroscopy (CD) was conducted in saline phosphate buffer (PBS) and in lipidic vesicles, using large unilamellar vesicles (LUV), composed of 2 dimyristoyl-sn-glycero-3-phosphoglycerol (DMPG) or bacterial membrane lipid. Antimicrobial activity of K11 and their analogs was evaluated in Gram-positive and Gram-negative bacterial strains. The scanning electron microscopy (SEM) micrographs of Staphylococcus aureus ATCC 25923 exposed to the Lys homopeptide at MIC concentration showed blisters and bubbles formed on the bacterial surface, suggesting that K11 exerts its action by destabilizing the bacterial membrane. CD analysis revealed a remarkably enhanced PPII structure of K11 when replacing some of its central residues by proline in PBS. However, when such peptide analogs were confronted with either DMPG-LUV or membrane lipid extract-LUV, the tendency to form PPII structure was severely weakened. On the contrary, K11 peptide showed a remarkably enhanced PPII structure in the presence of DMPG-LUV. Antibacterial tests revealed that K11 was able to inhibit all tested bacteria with an MIC value of 5 uM, while proline and alanine analogs have a reduced activity on Listeria monocytogenes. Besides, the activity against Vibrio parahaemolyticus was affected in most of the alanine-substituted analogs. However, lysine substitutions by alanine or proline at position 7 did not alter the activity against all tested bacterial strains, suggesting that this position can be screened to find a substitute amino acid yielding a peptide with increased antibacterial activity. These results also indicate that the PPII secondary structure of K11 is stabilized by the interaction of the peptide with negatively charged phospholipids in the bacterial membrane, though not being the sole determinant for its antimicrobial activity. PMID- 29468308 TI - Cross-sectional study of contraceptive use among Chinese women of reproductive age: results based on a mobile application (APP)-derived data. AB - PURPOSE: To evaluate the contraceptive status among Chinese women of reproductive age and factors associated with contraceptive methods. METHODS: A cross-sectional study from November 2015 to January 2016 was conducted. We used APP to collect demographics and contraceptive use information of women aged 14-44 years in China. RESULTS: A total of 23,669 women completed the study. After data cleaning, 19,768 (83.5%) women were included in the final analysis. The prevalence of contraceptive use was 78.9%; while 21.05% of women did not use any method, condoms (40.10%), rhythm, or withdrawal (31.03%) were the most commonly used methods. When contraceptive methods were divided into four categories-long-acting contraceptives (LAC), short-acting contraceptive (SAC), Others, and "No use"-the prevalence was 6.1% (601/19,678), 40.8% (8022/19,678), 35.1% (6912/19,678), and 21.1% (4143/19,678), respectively. Women with a high level of education, being unmarried, and sexually active women tended to choose SAC; married women were associated with LAC usage. Women with irregular menstrual cycle used a high proportion of emergency contraception. CONCLUSIONS: The prevalence of contraceptive use was 78.9%, with condom use being most prominent. Young women of reproductive age have low awareness of contraception. Relevant departments should take necessary measures to improve this situation. PMID- 29468309 TI - Factors associated with late fetal mortality. AB - PURPOSE: Perinatal mortality has been decreasing in Europe thanks to a reduction in neonatal mortality. The causes of fetal mortality remain poorly studied. The objective was to determine the late fetal mortality rate in Spain in 2015 and the associated factors. METHODS: A cross-sectional study was performed using data regarding births in 2015 in Spain extracted from the National Institute of Statistics. Single births at 28 or more weeks of pregnancy were included. The sample comprised 340,371 births. Sociodemographic, obstetrical and neonatal variables were analyzed using univariate and multivariate logistic regression (MLR), with the fetal mortality from 28 weeks of pregnancy as the dependent variable. RESULTS: The total number of late fetal deaths was 884 (2.6 * 1000). The MLR model showed that the following factors were associated with late fetal mortality: birth before 37 weeks of pregnancy (OR 13.1); weight of the newborn < 2500 g (OR 3.22) and >= 4000 g (OR 3.36); low training level (OR 2.28); and others, such as African origin, maternal age >= 35 years, primiparity and mothers who were single. CONCLUSIONS: The rate of late fetal mortality in Spain has not decreased and has remained at the same level as in 2010. This result is related to prematurity, low birth weight, macrosomia and sociodemographic factors, such as low maternal preparation, mothers of African origin, age >= 35 years and mothers who are single. It is necessary to improve the quality and accessibility of prenatal care and the early detection of risk factors. PMID- 29468310 TI - Cancer metastasizes to the bone marrow and not to the bone: time for a paradigm shift! PMID- 29468311 TI - 68Ga-PSMA-PET/CT imaging of localized primary prostate cancer patients for intensity modulated radiation therapy treatment planning with integrated boost. AB - PURPOSE: The purpose of our study was to show the feasibility and potential benefits of using 68Ga-PSMA-PET/CT imaging for radiation therapy treatment planning of patients with primary prostate cancer using either integrated boost on the PET-positive volume or localized treatment of the PET-positive volume. The potential gain of such an approach, the improvement of tumor control, and reduction of the dose to organs-at-risk at the same time was analyzed using the QUANTEC biological model. METHODS: Twenty-one prostate cancer patients (70 years average) without previous local therapy received 68Ga-PSMA-PET/CT imaging. Organs at-risk and standard prostate target volumes were manually defined on the obtained datasets. A PET active volume (PTV_PET) was segmented with a 40% of the maximum activity uptake in the lesion as threshold followed by manual adaption. Five different treatment plan variations were calculated for each patient. Analysis of derived treatment plans was done according to QUANTEC with in-house developed software. Tumor control probability (TCP) and normal tissue complication probability (NTCP) was calculated for all plan variations. RESULTS: Comparing the conventional plans to the plans with integrated boost and plans just treating the PET-positive tumor volume, we found that TCP increased to (95.2 +/- 0.5%) for an integrated boost with 75.6 Gy, (98.1 +/- 0.3%) for an integrated boost with 80 Gy, (94.7 +/- 0.8%) for treatment of PET-positive volume with 75 Gy, and to (99.4 +/- 0.1%) for treating PET-positive volume with 95 Gy (all p < 0.0001). For the integrated boost with 80 Gy, a significant increase of the median NTCP of the rectum was found, for all other plans no statistical significant increase in the NTCP neither of the rectum nor the bladder was found. CONCLUSIONS: Our study demonstrates that the use of 68Ga-PSMA-PET/CT image information allows for more individualized prostate treatment planning. TCP values of identified active tumor volumes were increased, while rectum and bladder NTCP values either remained the same or were even lower. However, further studies need to clarify the clinical benefit for the patients applying these techniques. PMID- 29468312 TI - Evaluation on the reliability of the permeability coefficient (Kp) to assess the percutaneous penetration property of chemicals on the basis of Flynn's dataset. AB - PURPOSE: The permeability coefficient (Kp) is often used for prediction of the dermal penetration of chemicals. Mathematical models have mostly been derived on Kp data basis. However, confusing Kp values are reported, questioning the general reliability of this parameter. In this study, we tested the plausibility of Kp values expressing the dermal penetration velocity (cm h-1) of chemicals on a larger dataset from literature. METHODS: Kp was applied for the calculation of the time for penetration through skin membranes of defined thickness (tCrossSkin). Kp values were obtained from Flynn's dataset (1990), containing data determined mostly under similar experimental conditions using diffusion cells. Further skin penetration parameters, e.g., times at which the chemicals were firstly measured in the receptor phase, lag times, steady-state times, and exposure duration, where available, were related to Kp values. The data congruence was tested comparing Kp values from Flynn's dataset with those reported in the EDETOX database. Variables, which could bias the results, such as different experimental protocols and research groups were also considered. RESULTS: Kp data for 94 chemicals matched the inclusion criteria were evaluated. According to the Kp values, 21 (22%) compounds would require longer than 100 h, and 20 (21%) further compounds longer than 10 h of exposure to penetrate skin membranes of ~ 0.01-2.5 mm thickness. Obviously, erroneous Kp were found in studies of almost all research groups in Flynn's database, indicating that neither the observer nor the experimental conditions alone biased the values. CONCLUSIONS: Our evaluation demonstrates high implausibility of Kp values to represent the dermal penetration velocity and supports general invalidity of the parameter for implementation in studies using skin membranes. The Kp should not be used to characterize the percutaneous penetration of chemicals or in risk assessment without verification.

AB - Cardiac imaging is central to today's pediatric cardiology practice not only to diagnose structural congenital defects and delineate cardiac and extracardiac anatomy but also for determining the hemodynamic impact of the structural defects and acquired pediatric diseases. Not so long ago, clinicians had to heavily rely on angiography as the main cardiac imaging modality to visualize the heart. Particularly, the development of echocardiography in the 1970s and 1980s together with the development of magnetic resonance imaging (MRI) and computed tomography (CT) resulted in a non-invasive diagnostic revolution with diagnostic catheterization becoming obsolete apart for very specific indications. The continuous improvements in non-invasive imaging modalities allow an unprecedented level of understanding of cardiac morphology and function. Over the last few years, the specific roles of the three imaging modalities and their complementary roles in diagnosis and treatment have become well established resulting in a multimodality approach to specific congenital lesions. Recently, multimodality guidelines were published for postoperative tetralogy of Fallot and patients with transposition of the great arteries (Cohen et al. J Am Soc Echocardiogr. 2016;29(7):571-621, Valente et al. J Am Soc Echocardiogr. 2014;27(2):111-41). In this paper, we aim to highlight some of the most significant advances and highlight some emerging trends in pediatric cardiac imaging. PMID- 29468315 TI - Comparative study of two spinous process (SP) osteotomy techniques for posterior decompression surgery in lumbar spinal stenosis: SP base versus splitting osteotomy. AB - PURPOSE: To compare the postoperative clinical and radiological outcomes of the SP base osteotomy versus SP splitting techniques for PD for treating LSS. METHODS: Of 139 patients who underwent PD surgery for LSS, 97 who met the study criteria were enrolled in the study. Group A comprised 53 patients who underwent SP base osteotomy, and group B included 44 patients who underwent SP splitting osteotomy. The primary study endpoint was intensity of lower back pain (LBP) and pain radiation to the lower extremities measured with the visual analogue scale (VAS). Secondary endpoints included (1) clinical outcomes assessed using Oswestry disability index and 12-short health form questionnaire; (2) surgical outcomes; and (3) procedure-related complications. RESULTS: LBP was more or less greater in SP base osteotomy group than in SP splitting osteotomy group at postoperative 1 week and 1 year (P = 0.04 and 0.03), but radiating pain was no significant difference between the groups throughout the 1-year follow-up period. One year after the surgery, the fusion rate at the osteotomized site was significantly greater in SP splitting osteotomy group (77%) than in SP base osteotomy group (55%) (P = 0.03). Clinical outcomes, surgical outcomes, and complications did not differ significantly between groups during follow-up times. CONCLUSIONS: The two SP osteotomy techniques offer excellent clinical and radiological outcomes at least for the first year after the surgery. In fusion rate at the osteotomized SP site, the SP splitting technique was superior to the SP base osteotomy technique. These slides can be retrieved under Electronic Supplementary Material. PMID- 29468316 TI - Delivery of Methotrexate and Characterization of Skin Treated by Fabricated PLGA Microneedles and Fractional Ablative Laser. AB - PURPOSE: This study investigated in vitro transdermal delivery of methotrexate through dermatomed porcine ear and cadaver human skin treated with poly (D,L lactide-co-glycolide) acid microneedles or fractional ablative laser. METHODS: PLGA microneedles were fabricated and characterized using scanning electron microscopy and mechanical assessment techniques. The integrity of treated skin was evaluated by rheometer, transepidermal water loss, and skin electrical resistance measurements. Successful skin microporation was demonstrated by dye binding, histology, pore uniformity, confocal laser microscopy, and DermaScan studies. In vitro permeation experiment was performed on Franz diffusion cells to determine drug delivery into and across the skin. RESULTS: Both physical treatments resulted in a considerable decrease in skin resistance and an increase in transepidermal water loss value. The laser-created microchannels were significantly larger than those formed by microneedles (p < 0.05). An effective force of 41.04 +/- 18.33 N was required to achieve 100% penetration efficiency of the microneedles. For both porcine ear and human skin, laser ablation provided a significantly higher methotrexate permeability into the receptor chamber and skin layers compared to microneedle poration and untreated skin (p < 0.05). CONCLUSIONS: Both fractional ablative laser and polymeric microneedles markedly enhanced in vitro transdermal delivery of methotrexate into and across skin. Graphical Abstract ?. PMID- 29468317 TI - Paucibacter aquatile sp. nov. isolated from freshwater of the Nakdong River, Republic of Korea. AB - A Gram-negative, aerobic, motile, and rod-shaped bacterial strain designated CR182T was isolated from freshwater of the Nakdong River, Republic of Korea. Optimal growth conditions for this novel strain were found to be: 25-30 degrees C, pH 6.5-8.5, and 3% (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequence indicates that the strain CR182T belongs to type strains of genus Paucibacter. Strain CR182T showed 98.0% 16S rRNA gene sequence similarity with Paucibacter oligotrophus CHU3T and formed a robust phylogenetic clade with this species. The average nucleotide identity value between strain CR182T and P. oligotrophus CHU3T was 78.4% and the genome-to-genome distance was 22.2% on average. The genomic DNA G+C content calculated from the genome sequence was 66.3 mol%. Predominant cellular fatty acids of strain CR182T were summed feature 3 (C16:1 omega7c and/or C16:1 omega6c) (31.2%) and C16:0 (16.0%). Its major respiratory quinine was ubiquinone Q-8. Its polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine, and two unidentified phospholipids. Its genomic DNA G+C content was 66.3%. Based on data obtained from this polyphasic taxonomic study, strain CR182T represents a novel species belonging to genus Paucibacter, for which a name of P. aquatile sp. nov. is proposed. The type strain is CR182T (= KCCM 90284T = NBRC 113032T). PMID- 29468318 TI - How grazing affects soil quality of soils formed in the glaciated northeastern United States. AB - Historically, much of the New England landscape was converted to pasture for grazing animals and harvesting hay. Both consumer demand for local sustainably produced food, and the number of small farms is increasing in RI, highlighting the importance of characterizing the effects livestock have on the quality of pasture soils. To assess how livestock affect pasture on Charlton and Canton soils series in RI, we examined soil quality in farms raising beef cattle (Bos taurus), sheep (Ovis aries), and horses (Equus ferus caballus), using hayed pastures as a control. We sampled three pastures per livestock type and three control hayed pastures in May, August, and October 2012. Hay fields and pastures grazed by sheep had statistically significant (P < 0.001) better soil quality than pastures grazed by beef cattle or horses. This was driven by parameters including penetration resistance, bulk density, aggregate stability, and infiltration rate. Hayfields also showed higher soil quality measures than grazed pastures for organic matter content and active C. In addition, significant differences in nitrate and phosphate concentrations were observed among livestock types. Respiration and infiltration rates, pH, and ammonium concentrations, on the other hand, did not differ significantly among pasture types. When all soil quality indicators in this study were weighed equally, soil quality scores followed the order: hay > sheep > beef cattle > horses. The results of our study provide baseline data on the effect different types of livestock have on pasture soil quality in RI, which may be useful in making sound land use and agricultural management decisions. PMID- 29468319 TI - First-principles study of the structural, elastic and electronic properties of SbXI (X=S, Se, Te) crystals. AB - The structural, elastic, elastic anisotropy and electronic properties of ferroelectric SbSI and paraelectric SbSI, SbSeI and SbTeI crystals were computed using the local density approximation with first-principle calculations, based on density functional theory. The independent elastic constants of SbXI compounds were computed and the results reveal that they are mechanically stable. Some polycrystalline quantities such as bulk modulus, shear modulus, acoustic velocities, Young's modulus, Poisson's ratio, elastic anisotropy and elastic Debye temperatures of these compounds were derived from computed elastic constants. Energy band structures show that these compounds have an indirect band gap. The electronic charge distribution and partial density of states of SbXI compounds indicate that the Sb-X bond is typically covalent with a strong hybridization as well as Sb-I compounds that have strong ionic character. The results obtained were compared with experimentally measured values and other theoretical data. PMID- 29468321 TI - Correction to: Metabolism of L-arabinose in plants.

PMID- 29468320 TI - Effect of Permeation Enhancers on the Buccal Permeability of Nicotine: Ex vivo Transport Studies Complemented by MALDI MS Imaging. AB - PURPOSE: The purpose of this study was to assess the effect of several chemical permeation enhancers on the buccal permeability of nicotine and to image the spatial distribution of nicotine in buccal mucosa with and without buccal permeation enhancers. METHODS: The impact of sodium taurodeoxycholate (STDC), sodium dodecyl sulphate (SDS), dimethyl sulfoxide (DMSO) and Azone(r) on the permeability of [3H]-nicotine and [14C]-mannitol (a paracellular marker) across porcine buccal mucosa was studied ex vivo in modified Ussing chambers. The distribution of nicotine, mannitol and permeation enhancers was imaged using using matrix-assisted laser desorption ionization mass spectrometry imaging (MALDI MSI). RESULTS: Despite STDC significantly increasing permeability of [14C] mannitol, no enhancing effect was seen on [3H]-nicotine permeability with any of the permeation enhancers. Rather, SDS and DMSO retarded nicotine permeability, likely due to nicotine being retained in the donor compartment. The permeability results were complemented by the spatial distribution of nicotine and mannitol determined with MALDI MSI. CONCLUSIONS: The buccal permeability of nicotine was affected in an enhancer specific manner, suggesting that nicotine primarily diffuses via the transcellular pathway. MALDI MSI was shown to complement ex vivo permeability studies and to be a useful qualitative tool for visualizing drug and penetration enhancer distribution in buccal mucosa.

AB - Heterodichogamy is defined as the presence of two flower morphs that exhibit the male and female functions at different times among individuals within a population. Heterodichogamy is regarded as an adaptation to promote outcrossing through enhanced inter-morph mating, together with a 1:1 morph ratio. However, in highly fragmented populations, the morph ratio may be more likely to be biased by stochastic events. In such a situation, individuals of a minority morph within a population are expected to have higher reproductive success than those of a majority morph, which may suffer from pollen shortages of the minority morph. In this paper, we evaluated mating patterns and male reproductive success in a highly fragmented population of Machilus thunbergii, a putative heterodichogamous evergreen laurel tree. Results of paternity analysis indicated that the selfing rate was not clearly different between the two morphs. In contrast, the proportion of intra-morph mating was higher in the majority-morph (MM) mother trees than in the minority-morph (MF) mother trees. Bayesian estimated male reproductive success indicated that male reproductive success was higher in minority-morph (MF) than in majority-morph (MM) mother trees. These findings indicate that (1) the majority morph mothers, suffering a shortage of the opposite morph pollen, could partly compensate for the reduced reproductive success by intra-morph mating rather than by selfing, and (2) negative-frequency dependent selection may be involved in the maintenance of the two morphs.

AB - More than 200 years ago the first attempts at thoracoscopy were made but only after its introduction 25 years ago has video-assisted thoracoscopic surgery (VATS) experienced rapid progress. Due to worldwide cooperation and international networking tremendous progress of the technique was made by thoracic surgeons on all continents developing the technique into a less invasive operating procedure on the thorax. For patients this meant improvement in the quality of life and ultimately better survival rates following lung cancer surgery. The VATS procedures are nowadays the preferred method unless the size and extent of the tumor prohibits a minimally invasive procedure. New trends in VATS are ambulatory, drainless or uniportal VATS, the latter being possible because insufflation of carbon dioxide is not necessary, allowing manipulation with multiple instruments through one small incision. The other trend is robotic assisted thoracic surgery. The benefits of the robotics are higher degrees of freedom for movement of the instruments. The development of VATS is nowadays a global one with North America and Asian countries being the most active protagonists, but European countries also play an important role in shaping the future of minimally invasive surgery. Modern media help to further promote the technique. PMID- 29468328 TI - [Metastasized intestinal neuroendocrine tumors: Surgery for ileus prophylaxis].

AB - INTRODUCTION AND HYPOTHESIS: For decades, the pubovesical (PV) sling has been in the armamentarium of the fistula surgeon for treating persistent urinary incontinence after successful fistula closure. We report our early experience with slings, and then also introduce a new "tight" PV sling technique for management of post-fistula urethral leak. Our hypothesis is that performance of tight slings might result in improved continence for women with persistent urinary incontinence after obstetric fistula closure. METHODS: Data from 120 patients in whom some type of sling procedure had been performed between 1996 and 2012 were extracted and labeled as "early slings." Beginning in October 2014, more complete data were recorded and a more uniform approach was undertaken in 40 patients. Data were extracted from their charts and recorded as "tight slings." This information was analyzed using Chi-squared analysis. RESULTS: Tight slings were more successful in patients who had less severe fibrosis and who had a shorter time since initial injury. Thirty percent of women who underwent tight slings had improved continence at follow-up. CONCLUSION: Persistent urinary incontinence despite successful surgical closure of obstetrical fistula remains a difficult problem. Tight slings may be warranted in an attempt to avoid urinary diversion. PMID- 29468332 TI - Evaluation of tongue volume and oral cavity capacity using cone-beam computed tomography. AB - The aims of this study were to reveal the usefulness of a newly developed method for measuring tongue volume (TV) and oral cavity capacity (OCC) and to assess the relationship between them. The tongue was coated with a contrast agent, and the TV and OCC were determined using cone-beam computed tomography (CBCT). We enrolled 20 adults who were scheduled to undergo CBCT to evaluate the relationship of the third molar roots to the alveolar nerve before molar extraction. Each participant's tongue was coated with a contrast agent, and CBCT of the tongue and oral cavity was performed. Using computer software, we evaluated reconstructed 3D images of the TV, oral cavity proper volume (OCPV), and OCC. The mean TV was 47.07 +/- 7.08 cm3. The mean OCPV and OCC were 4.40 +/- 2.78 cm3 and 51.47 +/- 6.46 cm3, respectively. There was a significant correlation between TV and OCC (r = 0.920; p < 0.01) but not between TV and OCPV. The mean TV/OCC ratio was 91 +/- 5%. The proposed method produced CBCT images that enabled effective measurement of TV and OCC. This simple method of measuring TV and OCC will be useful in the diagnosis on the tongues with abnormal size.

AB - Clean water, which is free from pathogens and toxic chemicals, is vital to human health. The blue planet is encountering remarkable challenges in meeting the ever increasing demands of clean water. The intention of this research study was to develop a water filter material that is capable of removing bacterial contaminants and heavy metals from fresh water using cost effective and easily fabricated biocompatible filter material. For this purpose, granular activated carbon (GAC) was coated with both hydroxyapatite (HAP) nanoflakes and turmeric extract (TE) (HAP/TE/GAC) which had been extracted from natural turmeric powder. In addition, GAC was coated only with HAP nanoflakes to synthesize HAP coated GAC (HAP/GAC) composite. Prepared HAP/GAC and HAP/TE/GAC were characterized using Fourier-transform infrared spectroscopy, X-ray diffractometry, scanning electron microscopy and UV-visible spectrophotometry. Antibacterial effect of the prepared nanocomposites, HAP/GAC and HAP/TE/GAC was compared with neat GAC using Gram negative bacteria Escherichia coli. Results showed that antibacterial studies of the synthesized nanocomposites exhibit effective antibacterial activity against E. coli compared with neat GAC alone. However, the composite HAP/TE/GAC revealed better activity than HAP/GAC. Heavy metal adsorption ability of the synthesized composites was carried out using Pb2+ ions at room temperature at different time intervals and different pH levels. The equilibrium adsorption data were assessed via Langmuir and Freundlich adsorption isotherm models for neat GAC, HAP/GAC and HAP/TE/GAC at pH 6. The equilibrium adsorption data for GAC, HAP/GAC and HAP/TE/GAC were well fitted with both Freundlich and Langmuir isotherm models in the given Pb2+ concentrations. The HAP/TE/GAC composite is capable of maintaining the natural function of GAC in addition to removal of bacterial contaminants and heavy metals, which can be used as a point-of-use water filter material. PMID- 29468334 TI - Characterizing the phosphorus forms extracted from soil by the Mehlich III soil test. AB - Phosphorus (P) can limit crop production in many soils, and soil testing is used to guide fertilizer recommendations. The Mehlich III (M3) soil test is widely used in North America, followed by colorimetric analysis for P, or by inductively coupled plasma-based spectrometry (ICP) for P and cations. However, differences have been observed in M3 P concentrations measured by these methods. Using 31P nuclear magnetic resonance (P-NMR) and mass spectrometry (MS), we characterized P forms in M3 extracts. In addition to the orthophosphate that would be detected during colorimetric analysis, several organic P forms were present in M3 extracts that would be unreactive colorimetrically but measured by ICP (molybdate unreactive P, MUP). Extraction of these P forms by M3 was confirmed by P-NMR and MS in NaOH-ethylenediaminetetraacetic acid extracts of whole soils and residues after M3 extraction. The most abundant P form in M3 extracts was myo-inositol hexaphosphate (myo-IHP, phytate), a compound that may not contribute to plant available P if tightly sorbed in soil. Concentrations of myo-IHP and other organic P forms varied among soils, and even among treatment plots on the same soil. Extraction of myo-IHP in M3 appeared to be linked to cations, with substantially more myo-IHP extracted from soils fertilized with alum-treated poultry litter than untreated litter. These results suggest that ICP analysis may substantially over-estimate plant-available P in samples with high MUP concentrations, but there is no way at present to determine MUP concentrations without analysis by both colorimetry and ICP. This study also tested procedures that will improve future soil P-NMR studies, such as treatment of acid extracts, and demonstrated that techniques such as P-NMR and MS are complimentary, each yielding additional information that analysis by a single technique may not provide. PMID- 29468335 TI - Use of speckle-tracking strain in preload-dependent patients, need for cautious interpretation! AB - BACKGROUND: In critical patients, left ventricular ejection fraction and fractional shortening are used to reflect left ventricular systolic function. An emerging technique, two-dimensional-strain echocardiography, allows assessment of the left ventricle systolic longitudinal deformation (global longitudinal strain) and the speed at which this deformation occurs (systolic strain rate). This technique is of increasing use in critical patients in intensive care units and in the peri-operative period where preload constantly varies. Our objective, in this prospective single-center observational study, was to evaluate the effect of fluid resuscitation on two-dimensional-strain echocardiography measurements in preload-dependent critically ill patients. We included 49 patients with preload dependence attested by an increase of at least 10% in the left ventricular outflow track velocity-time integral measured by echocardiography during a passive leg raising maneuver. Echocardiography was performed before fluid resuscitation (echocardiography 1) and after preload independency achievement (echocardiography 2). RESULTS: Two-dimensional-strain echocardiography was feasible in 40 (82%) among the 49 patients. With preload dependence correction, the absolute value of global longitudinal strain and systolic strain rate was significantly increased from, respectively, - 13.3 +/- 3.5 to - 18.4% +/- 4.5 (p < 0.01) and - 1.11 s-1 +/- 0.29 to - 1.55 s-1 +/- 0.55 (p < 0.001). The fluid resuscitation affects GLS and SSR in preload-dependent patients, with a shift, for GLS, from pathological to normal values. CONCLUSION: In critically ill patients, the assessment of the systolic function by two-dimensional-strain echocardiography needs prior evaluation of preload dependency, in order to adequately interpret this variable. Future studies should assess the ability of global longitudinal strain to guide fluid management in the critically ill patients. PMID- 29468337 TI - Psychosocial Impact of a Positive Gene Result for Asymptomatic Relatives at Risk of Hypertrophic Cardiomyopathy. AB - Families with a history of hypertrophic cardiomyopathy (HCM) may be offered genetic testing in addition to clinical surveillance. Asymptomatic family members who are gene positive (silent gene carriers) represent a new group of "patients" who may not develop HCM, with little evidence available to assist clinical management. This study explored experiences of HCM genetic testing to identify potential benefits and harms. Thirty-two individuals previously offered genetic testing for HCM were recruited. Semi-structured interviews were conducted face-to face or by phone, and transcribed audio-recordings were coded using framework analysis. Key themes were as follows: (1) helping the next generation, (2) misunderstanding risk, (3) discrepancy between actual/perceived impact. Participants described multiple psychological (shock, worry, uncertainty) and behavioural (career, sport, insurance, family planning) consequences, depending on perceived risk. Most considered only the benefits of genetic testing for children or grandchildren, but there were some cases of significant adverse impact. The interpretation of the HCM genetic test result is variable for silent gene carriers and can lead to psychological and behavioural changes. The impact of a positive gene result may be mitigated by increased clarity of the clinical consequences and efforts to ensure informed decision-making, highlighting even further the important role of cardiac genetic counselling. PMID- 29468336 TI - Parenting a Child with Phenylketonuria (PKU): an Interpretative Phenomenological Analysis (IPA) of the Experience of Parents. AB - Phenylketonuria (PKU) is a rare inherited metabolic disorder which can cause neurological damage if left untreated. PKU is identified through newborn screening in developed countries, and treatment begins immediately to prevent these severe consequences. When a child is diagnosed, parents must assume immediate responsibility for the management of PKU and prevention of neurological damage. Quantitative studies have identified significant psychosocial stressors for parents, but little is known about how the parents experience this process. This study aimed to explore the experiences of parents of children with PKU under the age of two. It is the first study to examine these experiences in this way. Seven parents were interviewed about their experiences, and interpretative phenomenological analysis was used to analyse the data. Three main themes were identified: control, striving for normality and acceptance of PKU as a continuum. Links between the themes and processes underpinning the results were explored with relation to existing literature and theories from a clinical psychology perspective. The role of acceptance of PKU was central to the parent's experiences. Clinical implications and suggestions for further research are discussed.

AB - This study aimed to explore whether vitamin D receptor (VDR) polymorphisms are associated with susceptibility to systemic lupus erythematosus (SLE). Meta analyses were conducted to determine the associations between the VDR FokI, TaqI, and ApaI polymorphisms and SLE in all subjects and each ethnic group. A total of 12 studies were considered in the meta-analysis, which involved 1974 patients and 2506 controls. Meta-analysis of the VDR FokI polymorphism showed no association between SLE and the FokI F allele in all study subjects (OR = 1.047, 95% CI = 0.781-1.403, p = 0.758). However, the meta-analysis showed a significant association between SLE and the VDR FokI F allele in the Arab population (OR = 1.721, 95% CI = 1.417-2.088, p < 0.001). Analysis using the recessive and dominant models and homozygote contrast showed the same pattern for the VDR FokI F allele in Europeans, Asians, and Arabs. This meta-analysis showed that polymorphisms in VDR FokI, TaqI, and ApaI are not associated with SLE susceptibility in overall, European and Asian populations. However, the VDR FokI polymorphism is associated with SLE susceptibility in the Arab population. PMID- 29468339 TI - Residual disease activity in rheumatoid arthritis patients treated with subcutaneous biologic drugs that achieved remission or low disease activity: a longitudinal observational study. AB - The aim of this study was to evaluate the residual disease activity (RDA) and function in rheumatoid arthritis (RA) patients treated with subcutaneous biologic drugs that achieved a status of remission and low disease activity (LDA) according to the various indices validated for RA and to explore the factors associated with RDA. We consecutively enrolled RA patients that started a new subcutaneous biologic treatment. At baseline and after 3 and 6 months of treatment, we assessed the rate of patients that achieved remission or LDA using the Disease Activity Score on 28 joints, Clinical Disease Activity Index, Simplified Disease Activity Index, and American College of Rheumatology/European League Against Rheumatism remission criteria. The presence of RDA was evaluated as the rate of patients with at least tender joint count > 1, swollen joint count > 1, pain on VAS > 10 mm, general health (VAS) > 10, patient's disease activity (VAS) > 10, physician disease activity (VAS) > 10, and C reactive protein > 1 mg/dl. We also evaluated the impaired function defined as HAQ score > 0.5. Factors associated to RDA were also investigated. Ninety-three adult patients with RA were enrolled. At 6 months, RDA occurred mostly at the level of Patient's reported outcome items and less frequently in tender and swollen joints and acute phase reactants. Interestingly, about one fourth of patients in LDA and up to one fifth of patients in remission had residual functional impairment with an HAQ score greater than 0.5. RDA in RA was present even in patients with remission or LDA, especially for the patient's reported outcome. Impaired function was also present in a significantly rate of patients. PMID- 29468340 TI - Phrasing of the patient global assessment in the rheumatoid arthritis ACR/EULAR remission criteria: an analysis of 967 patients from two databases of early and established rheumatoid arthritis patients. AB - The ACR/EULAR Boolean remission criteria for rheumatoid arthritis (RA) include a strict cutoff for patient global assessment (PGA, value <= 1/10). Near-remission corresponds to remission for joint counts and C-reactive protein but with PGA > 1. The objective was to explore whether the contribution of PGA to remission and near-remission varied according to the wording of the PGA and in relation to disease duration. In patients with early arthritis (N = 731, French ESPOIR cohort) or established RA (N = 236 patients from across Europe), frequency of remission versus near-remission was assessed according to the phrasing used for PGA (global health versus disease activity). In 967 patients (mean [standard deviation] age 49.7 [12.7] years, 76.7% women), remission was infrequent: range 12.9-16.7% (according to wording of PGA) in early RA and 6.8-7.2% in established RA. Near-remission was more frequent: 13.0-16.8% in early RA and 13.1-13.6% in established RA. The ratio of remission to near-remission was higher in the early arthritis cohort (0.8-1.3 versus 0.5-0.5 in established RA). Using the disease activity PGA led to more remission and less near-remission than the global health PGA in the early arthritis cohort (12.9 vs 16.7% near-remission, respectively, p = 0.047) but not in established RA. The proportion of patients who can be classified as remission or near-remission differs in early RA compared to establish RA and depends upon the formulation of the PGA question. PGA referring to disease activity and not global health may be preferred in early disease, if the objective is more alignment with inflammation assessment. PMID- 29468341 TI - MRI-based detection of renal artery abnormalities related to renal denervation by catheter-based radiofrequency ablation in drug resistant hypertensive patients. AB - OBJECTIVES: Endovascular renal denervation (RDN) using catheter-based radiofrequency (RF) ablation has emerged as a potential treatment option for drug resistant hypertension. Its efficacy is currently under debate. We aimed to evaluate the capability of contrast-enhanced magnetic resonance imaging (MRI) to assess the effects of RDN on the renal arterial wall in patients presenting with drug-resistant hypertension. METHODS: Patients were included prospectively following institutional review board approval and written informed consent. Renal arteries were imaged using a two-dimensional T1-weighted TSE sequence pre- and post-administration of a gadolinium-based contrast agent, before (D0), 2 days (D2) and 6 months (M6) after RDN. Mean enhancement of the wall (mENH) and mean wall thickness (mWT) were compared across time using an ANOVA with repeated measures and post-hoc paired t-test. RESULTS: Follow-up was completed for 23 patients (median age, 57 years; 16 men). The mENH at D2 (96.3 +/- 36.0 %) was significantly higher than at D0 (61.1 +/- 26.3%, p < 0.001) and M6 (66.1+/-22.7%, p < 0.001). Similarly, mWT was significantly higher at D2 (3.1 +/- 0.4 m) than at D0 (2.7 +/- 0.4mm, p < 0.001) and M6 (2.9 +/- 0. 5 mm, p = 0.002). CONCLUSIONS: MRI demonstrated abnormalities of the arterial wall 2 days after RDN that had resolved at 6 months. KEY POINTS: * Contrast-enhanced MRI provides anatomic evidence of renal artery RF ablation * Temperature increase related to RF ablation induces transient arterial wall inflammation * Morphological effects observed 2 days post RF ablation are not visible after 6 months.

AB - Labour absenteeism may be detrimental to firms and society because of the economic costs, organizational problems and production cuts that it involves. Although involuntary absenteeism due to accident or illness that prevents workers from performing their work is unavoidable, avoidable voluntary absenteeism may also emerge due to asymmetric information given that neither employers nor doctors have perfect information about workers' health status. Assuming that there is heterogeneity in individual's behaviour and thus some workers are more likely to take sick leave than others due to differences in observable and unobservable characteristics, we specify a Finite Mixture Model to analyse sick leave days per year using a sample of employees from the 2014 European Health Survey in Spain. This specification accounts for unobserved heterogeneity in a discrete way assuming that there are two types of workers even though the data do not allow us to identify which group any individual belongs to. Our results reveal that, although health indicators have the greatest impact on the proportional change in days of absenteeism, there is heterogeneity in sick leave decisions and individual and job characteristics have different effect on the absenteeism of each group.

PMID- 29468344 TI - Co-development of Problem Gambling and Depression Symptoms in Emerging Adults: A Parallel-Process Latent Class Growth Model. AB - This study examines whether there are multiple joint trajectories of depression and problem gambling co-development in a sample of emerging adults. Data were from the Manitoba Longitudinal Study of Young Adults (n = 679), which was collected in 4 waves across 5 years (age 18-20 at baseline). Parallel process latent class growth modeling was used to identified 5 joint trajectory classes: low decreasing gambling, low increasing depression (81%); low stable gambling, moderate decreasing depression (9%); low stable gambling, high decreasing depression (5%); low stable gambling, moderate stable depression (3%); moderate stable problem gambling, no depression (2%). There was no evidence of reciprocal growth in problem gambling and depression in any of the joint classes. Multinomial logistic regression analyses of baseline risk and protective factors found that only neuroticism, escape-avoidance coping, and perceived level of family social support were significant predictors of joint trajectory class membership. Consistent with the pathways model framework, we observed that individuals in the problem gambling only class were more likely using gambling as a stable way to cope with negative emotions. Similarly, high levels of neuroticism and low levels of family support were associated with increased odds of being in a class with moderate to high levels of depressive symptoms (but low gambling problems). The results suggest that interventions for problem gambling and/or depression need to focus on promoting more adaptive coping skills among more "at-risk" young adults, and such interventions should be tailored in relation to specific subtypes of comorbid mental illness. PMID- 29468345 TI - Social Explanations of Lottery Play: New Evidence Based on National Survey Data. AB - This study examines the social contexts of gambling and analyzes social motivations for playing the lottery. We test three sociological approaches simultaneously: network effects, consumption theory, and strain theory. The data used (SOEP-IS, N = 5868 individuals) has several advantages beyond being a large scale representative sample of the German population. With information on households, we can analyze social network effects while avoiding the problems of egocentric network data. Another benefit of the SOEP-IS is the panel structure. We use the panel structure to improve measurements of strain theory by using the decline in income over time as a measure for it. Our results suggest that the three theories explain different aspects of lottery play. Networks seem to have an influence on lottery play. Having another person in the household playing the lottery is positively associated with both the probability of playing (regularly) and expenditures on lottery tickets. Daydreams and the belief in good luck are positively associated with lottery play as well. Strain theory is confirmed insofar as we find that a decline in income is significantly related to expenditures but not to the probability of playing the lottery. Overall, this study suggests that people play the lottery depending on their social surroundings, their desire to participate in a world normally out of their reach, and the tensions they feel from the distance between their aspirations and their actual social position. PMID- 29468346 TI - Drivers of Sexual Inactivity Among Women Living with HIV and AIDS: Findings of the GENIH Study in Sao Paulo, Brazil. AB - The advances on HIV/AIDS diagnosis and treatment have enabled people living with HIV/AIDS (PLHA) better quality of life. However, the persistence of HIV-related stigma and discrimination, and the risks triggered by HIV disclosure, may be a barrier to the sexual exercise of PLHA. We investigated the prevalence of sexual inactivity and the reasons given for it among a representative sample of women of reproductive age living with HIV/AIDS (WLWHA) in the municipality of Sao Paulo, Brazil. We surveyed 918 WLWHA with probability proportional to average number of visits in each of the 18 referral HIV/AIDS services. Sexual inactivity was defined as not having had vaginal sexual intercourse in the year prior to research. Statistical modeling of the factors associated with sexual inactivity was carried out by way of bivariate and multivariate analysis. In all, 22.2% (n = 200) of the women did not have sexual relations in the year prior to the interview. The majority reported a reduction in desire (64.5%) and sexual activity (68%). Among the women not in a relationship, the predictors of sexual inactivity were: being older (35-49) (ORa = 2.25); not being Catholic (ORa = 2.91); having kept the diagnosis secret from their partner (ORa = 2.45); having had up to five sexual partners throughout life (ORa = 3.81). The diagnosis of HIV seems to have more of an effect on the desire for and frequency of sexual activity than on its interruption. Sexual inactivity was influenced by the stigma of HIV/AIDS, by age, and by moral-religious values.

AB - Soils are often complex habitats inhabited by a wide range of organisms, some harmful to plants and others beneficial, for example by attacking harmful organisms. Beneficial organisms include predatory mites, some of which have been commercialized for biological control of pest insects and mites. The objective of this work was to evaluate under laboratory condition the suitability of representative soil insect and mite pests, especially Aceria tulipae (Keifer), as prey to the soil-inhabiting predatory mites Proctolaelaps bickleyi (Bram) and Cosmolaelaps brevistilis (Karg). Predation, oviposition and survivorship of recently molted adult females of the predators were assessed in the dark in rearing chambers at 25 +/- 1 degrees C and 75 +/- 3% RH. Predation rate by P. bickleyi on A. tulipae was significantly higher than that by C. brevistilis (196.3 vs. 71.0 specimens/day). About 482 A. tulipae were preyed by each P. bickleyi at each day, when 500 A. tulipae were made available daily to the predator. Oviposition rate on that prey was also higher for P. bickleyi (4.2 eggs/day). For C. brevistilis, the highest level of oviposition was on Caliothrips phaseoli (Hood) (1.2 eggs/day). Survivorship was always higher for C. brevistilis (>= 70%), given its ability to remain alive relatively long even in the absence of prey. High rates of survivorship of P. bickleyi were observed on A. tulipae, Bradysia matogrossensis (Lane) and Protorhabditis sp. Promising results were obtained for P. bickleyi on A. tulipae and even on other prey, justifying the conduction of complementary studies under field condition. PMID- 29468348 TI - Effects of a mulch layer on the assemblage and abundance of mesostigmatan mites and other arthropods in the soil of a sugarcane agro-ecosystem in Australia. AB - Sugarcane farmers can utilise a soil conservation technique called green cane trash blanketing, a form of mulching that can increase plant productivity through a number of channels, e.g., via altering soil physical, chemical and biological characteristics, and influence soil arthropod assemblages. Predatory mites (Mesostigmata) are important components of soil communities because they can control populations of other soil-dwelling pest species. Our aim was to characterise mulch-influenced predatory Mesostigmata community assemblages in sugarcane soils in Queensland, Australia. We found that application of a mulch layer significantly increased the abundance of Mesostigmata, and oribatid mites and collembolans, in soils. Furthermore, we observed that the assemblages of Mesostigmata in soil covered by mulch were significantly different to those in bare soil; and the assemblages of Mesostigmata changed over time. The assemblages of Mesostigmata, but not Oribatida or collembolans, were significantly different in soil under mulch depending on whether the mulch was freshly laid, or decomposing. Our results show that the use of mulch, specifically the green cane trash blanket, can increase overall microarthropod abundance including Mesostigmata. This is likely due to increased habitat complexity and changing resource availability. PMID- 29468349 TI - Prediction of Therapeutic Response to Cyclooxygenase Inhibitors in Preterm Infants with Patent Ductus Arteriosus. AB - Patent ductus arteriosus (PDA) is a morbid condition commonly seen in premature infants. Cyclooxygenase (COX) inhibitors, such as indomethacin and ibuprofen, are often used for the treatment of PDA in preterm infants, and they work by reducing the production of prostaglandin. However, as observed in clinical practice, not all PDAs in preterm infants can be closed using COX inhibitors. Some studies have demonstrated that gestational age, birth weight, B-type natriuretic peptide (BNP), and ductal diameter can predict the therapeutic responsiveness to COX inhibitors. This paper reviews the factors that can predict successful closure of the PDA in preterm infants using indomethacin or ibuprofen and presents new opinions and recent findings on this topic, including the predictive roles of intrauterine growth restriction, timing of the treatment, and the importance of platelet count and arterial pH. We also discuss the prospects for future studies to improve the individualized therapy of PDA in premature neonates. PMID- 29468351 TI - Large Calibre Self-Expanding Stents for Pulmonary Stenosis After the Arterial Switch, a Low-Risk Solution to a Low-Flow Situation. AB - Branch pulmonary artery stenosis is one of the most common complications late after the arterial switch operation. The pathophysiology of stenosis in these circumstances is very different to that encountered in with normally related great vessels. The LeCompte manoeuvre leaves the pulmonary arteries straddled and stretched over the aortic root which contributing significantly to the degree of stenosis encountered. Unilateral branch pulmonary artery stenosis rarely leads to significant symptoms in young patients with biventricular repairs; however, significant discrepancies in the split flows between right and left lung may place the patient in an unfavourable physiological position as they move in to middle age. Balloon expandable stent implantation distorts the anatomical arrangement of the LeCompte and is associated with negative interactions with the often dilated aortic root. We present three cases of the use of flexible self expanding stents to improve the physiological flow distributions to each lung whilst hopefully decreasing the risk of erosion and perforation or fistula formation related to the pulmonary artery. All three patients had uncomplicated procedures with significant improvements in vessel diameter and flow distribution noted on follow-up MRI scans. This is the first report of the use of self expanding stents in the context of branch pulmonary artery stenosis after the LeCompte manoeuvre. Theoretically and based on our early experience, this technique provides potential safety advantages over the use of more traditional balloon expandable stents. PMID- 29468350 TI - A Novel MEF2C Loss-of-Function Mutation Associated with Congenital Double Outlet Right Ventricle. AB - Congenital heart defect (CHD) represents the most prevalent birth defect, and accounts for substantial morbidity and mortality in humans. Aggregating evidence demonstrates the genetic basis for CHD. However, CHD is a heterogeneous disease, and the genetic determinants underlying CHD in most patients remain unknown. In the present study, a cohort of 186 unrelated cases with CHD and 300 unrelated control individuals were recruited. The coding exons and flanking introns of the MEF2C gene, which encodes a transcription factor crucial for proper cardiovascular development, were sequenced in all study participants. The functional effect of an identified MEF2C mutation was characterized using a dual luciferase reporter assay system. As a result, a novel heterozygous MEF2C mutation, p.R15C, was detected in an index patient with congenital double outlet right ventricle (DORV) as well as ventricular septal defect. Analysis of the proband's pedigree showed that the mutation co-segregated with CHD with complete penetrance. The missense mutation, which changed the evolutionarily conserved amino acid, was absent in 300 control individuals. Functional deciphers revealed that the mutant MEF2C protein had a significantly decreased transcriptional activity. Furthermore, the mutation significantly reduced the synergistic activation between MEF2C and GATA4, another transcription factor linked to CHD. This study firstly associates MEF2C loss-of-function mutation with DORV in humans, which provides novel insight into the molecular pathogenesis of CHD, suggesting potential implications for genetic counseling and personalized treatment of CHD patients. PMID- 29468352 TI - Local excision for ypT2 rectal cancer following preoperative chemoradiation therapy: it should not be justified. AB - PURPOSE: Among individuals who respond well to preoperative chemoradiation therapy (CRT) for ypT0-1, local excision (LE) could provide acceptable oncological outcomes. However, in ypT2 cases, the oncological safety of LE has not been determined. This study aimed to compare oncological outcomes between LE and total mesorectal excision of ypT2-stage rectal cancer after chemoradiation therapy and investigate the oncological safety of LE in these patients. METHODS: We included 351 patients who exhibited ypT2-stage rectal cancer after CRT followed by LE (n = 16 [5%]) or total mesorectal excision (TME) (n = 335 [95%]) after preoperative CRT between January 2007 and December 2013. After propensity matching, oncological outcomes between LE group and TME group were compared. RESULTS: The median follow-up period was 57 months (range, 12-113 months). In the LE group, local recurrence occurred more frequently (18 vs. 4%; p = 0.034) but not distant metastases (12 vs. 11%; p = 0.690). The 5-year local recurrence-free (76 vs. 96%; p = 0.006), disease-free (64 vs. 84%; p = 0.075), and overall survival (79 vs. 93%; p = 0.045) rates of the LE group were significantly lower than those of the TME group. After propensity matching, 5-year local recurrence free survival of the LE group was significantly lower than that of the TME group (76 vs. 97%, p = 0.029). CONCLUSION: The high local failure rate and poor oncological outcomes for ypT2-stage rectal cancer patients who undergo CRT followed by LE cannot be justified as an indication for LE. Salvage surgery should be recommended in these patients. PMID- 29468353 TI - Is the obesity a risk factor for delayed colonic post-polypectomy bleeding? authors' reply. PMID- 29468354 TI - Outcomes and prognostic factors of multimodality treatment for locally recurrent rectal cancer with curative intent. AB - PURPOSE: Radical management of locally recurrent rectal cancer (LRRC) can lead to prolonged survival. This study aims to assess outcomes and identify prognostic factors for patients with LRRC treated using a multimodality treatment protocol. METHODS: An analysis of a prospectively maintained institutional database of consecutive patients who underwent radical surgical resection for LRRC was performed. Potential prognostic factors were investigated using a Cox proportional hazards model. RESULTS: Ninety-eight patients were included in this study. A multimodality approach was taken in the majority, including preoperative chemoradiation (78%), intraoperative radiation therapy (47%) and adjuvant chemotherapy (41%). Extended resection was performed where required: bone resection (34%) and lateral pelvic sidewall dissection (31%). The rate of R0 resection was 66%. Estimated rates of 5-year overall survival (OS) and progression-free survival (PFS) were 41.8% (95% CI 32.5-53.7) and 22.5% (95% CI 15.3-33.1). On multivariate analysis, stage III disease at initial primary surgery, a positive margin at initial primary surgery, synchronous or previously resected oligometastases, a lateral or sacral invasive-type pelvic recurrence and the requirement for IORT all predicted for inferior PFS (p < 0.05). Eleven percent of patients subsequently underwent further pelvic surgery for pelvic re recurrence and had an estimated 5-year OS rate of 54.5% (95% CI 29.0-100.0) from repeat surgery. CONCLUSIONS: Radical multimodality management of LRRC leads to prolonged survival in approximately 40% of patients. Those with sacral or lateral invasive-type recurrence or oligometastatic disease have inferior outcomes and further research is needed to optimise treatment for these groups. PMID- 29468355 TI - Incidental findings in multislice computed tomography prior to transcatheter aortic valve implantation: frequency, clinical relevance and outcome. AB - Multislice computed tomography (MSCT) has emerged as the mainstay in patients planned for transcatheter aortic valve implantation (TAVI). Incidental findings (IF) in MSCT are common. However, the exact incidence, clinical relevance and further consequences of IF are unclear and it is controversial whether IF adversely affect patients' outcome. We analyzed MSCT data of 1050 patients screened for TAVI between January 2011 and December 2014. Median follow-up of patients was 20 months. In total, 3194 IF were identified, which were classified into clinically non-relevant IF (2872, 90%) and clinically relevant IF (322, 10%). In 25% of patients (258/1050) at least one clinically relevant IF was present. Age (80 +/- 7 vs. 80 +/- 7 years; p = 0.198) and EuroSCORE II (3.6% [2.1 5.7] vs. 3.6% [2.1-5.9]; p = 0.874) was similar between patients with and without a clinically relevant IF. TAVI was performed less frequently in patients with a clinically relevant IF (76% vs. 85%; p < 0.001), with more patients receiving surgical aortic valve replacement in that group (14% vs. 11%; p = 0.042), possibly due to the high rate of incidental aneurysms of the ascending aorta (n = 48). If TAVI was performed mortality did not differ (30-days: 4% vs. 3%; p = 0.339, 1-year: 11% vs. 14%; p = 0.226) between patients with and without a clinically relevant IF. Our study is the largest study to analyze prevalence, clinical relevance and therapeutic consequences of IF during screening for TAVI. IF in pre-procedural MSCT are common and clinically relevant in one-quarter of patients. However, these findings had no impact on overall mortality. PMID- 29468356 TI - Reciprocal Relations Between Parenting Behaviors and Conduct Disorder Symptoms in Preschool Children. AB - Reciprocal relations between children's conduct disorder (CD) symptoms and parenting behaviors were examined across the preschool years. Participants were 199 children (M = 44.26 months, SD = 3.37; 92 girls) and their 199 mothers and 158 fathers. CD symptoms were assessed via structured interviews; parenting was assessed via observational and self-report measures. Fixed effects models were used to assess within-individual changes and traditional cross-lagged models were used to assess between-individual changes; comparisons by sex were also carried out. Increases in maternal overreactivity predicted increases in CD symptoms. During the later preschool years, decreases in maternal warmth predicted increases in CD symptoms and increases in CD symptoms predicted increases in paternal overreactivity. Reciprocal effects were found between girls' CD symptoms and paternal negative affect. Findings suggest maternal and paternal influence on the development of CD symptoms and suggest that CD symptoms influence fathers' parenting during the preschool years. PMID- 29468357 TI - Sensitive Fathering Buffers the Effects of Chronic Maternal Depression on Child Psychopathology. AB - Maternal depression across the first years of life carries long-term negative consequences for children's well-being; yet, few studies focused on fathers as potential source of resilience in the context of chronic maternal depression. Utilizing an extreme-case design, a community birth cohort of married/cohabitating mothers (N = 1983) with no comorbid risk was repeatedly tested for maternal depression across the first year and again at 6 years, leading to two matched cohorts; 46 mothers with chronic depression and 103 non depressed controls. At 6 years, mother and child underwent psychiatric diagnosis and mother-child and father-child interactions observed. Partners of depressed mothers exhibited reduced sensitivity, lower reciprocity, and higher tension during interactions, particularly among children with psychopathology. Maternal depression increased child propensity to display Axis-I disorder upon school entry by fourfold. Sensitive fathering reduced this risk by half. Findings underscore the father's resilience-promoting role in cases of maternal depression and emphasize the need for father-focused interventions. PMID- 29468359 TI - ? PMID- 29468358 TI - ? PMID- 29468360 TI - Bariatric Surgery Coverage: a Comprehensive Budget Impact Analysis from a Payer Perspective. AB - OBJECTIVE: The objective of this study was to estimate a payer's budget impact of bariatric surgery coverage under (1) unrestricted, (2) budget-restricted ($500,000/year), and (3) quantity-restricted (100/year) medical benefit plan scenarios versus non-coverage in general and type 2 diabetes mellitus (T2DM) populations over a 10-year period. METHODS: Using recently published literature and health technology assessment reports, the model evaluated a hypothetical payer population of 100,000 members under current real-world trends: BMI-defined obesity groups (31.3% normal/underweight, 33% overweight, 20.4% obese, 9% severely obese and 6.3% morbidly obese), T2DM prevalence (6.7-27.5%; 100% for the T2DM model), surgery type (LAGB, BPD/DS, VSG, and RYGB), and differential outcomes (T2DM resolution, costs, and reoperation and complications rates). Assuming a surgery election rate of 1.42% among eligible candidates with a 3% discount rate and 10% annual surgery turnover rate, the model calculated the incremental cost per-member-per-month (PMPM) by estimating the difference in total non-T2DM and T2DM-related expected costs and savings. One-way (+/- 25%) sensitivity analysis was performed. RESULTS: The impact of covering bariatric surgery under multiple scenarios for a general (or T2DM) population ranged from an additional $0.3 to $3.6 (T2DM: $0.3 to $10.5) PMPM in year 1. Incremental costs diminished over time, breaking even between years 5 and 9 (T2DM: 5-6), and by year 10, cost savings were estimated to be between $1.5 and $4.8 (T2DM: $1.2 and $31.8). CONCLUSION: Providing bariatric surgery coverage may have a modest short-term budget impact increase but would lead to long-term net cost savings in a general population model. The cost savings were much more pronounced in the T2DM model. PMID- 29468361 TI - Establishment of a multiplex real-time RT-PCR assay for rapid identification of H6 subtype avian influenza viruses. AB - The H6 subtype avian influenza viruses (AIVs) possess the capacity for zoonotic transmission from avian species to humans. Establishment of a specific, rapid and sensitive method to screen H6 AIVs is necessary. Based on the conserved domain of the matrix and H6 AIV hemagglutinin genes, two TaqMan minor-groove-binder probes and multiplex real-time RT-PCR primers were designed in this study. The multiplex real-time RT-PCR assay developed in this study had high specificity and repeatability and a detection limit of 30 copies per reaction. This rapid diagnostic method will be useful for clinical detection and surveillance of H6 AIVs in China. PMID- 29468362 TI - Development of a nanogold slot blot inhibition assay for the detection of antibodies against bovine herpesvirus type 1. AB - Bovine herpesvirus type 1 (BoHV-1) is recognized as an important pathogen causing respiratory, reproductive, and neurological disorders in cattle and is associated with economic losses to animal industry. Accurate diagnostic methods are needed for prevention of disease transmission. While the virus neutralization test is considered the gold standard method, it requires maintenance of the virus and cell cultures, which is time consuming and expensive. Serological techniques such as enzyme-linked immunosorbent assay (ELISA) are widely applied, as these are easy to perform and provide quick results. In the present study, a nanogold slot blot inhibition assay was developed for the serological diagnosis of BoHV-1 and compared with standard ELISA and horseradish peroxidase (HRP) slot blot assays. Of 42 serum samples tested by ELISA, 32 (76.2%) were positive and 10 (23.8%), were negative. The sensitivity and specificity of the nanogold slot blot inhibition assay was similar to that observed for ELISA and HRP slot blot assays, and a strong correlation was observed between the tests. Thus, the nanogold slot blot inhibition assay may serve as an efficient and rapid alternative to ELISA in settings, where plate-reading equipment is lacking. PMID- 29468363 TI - The BCR-ABL inhibitor nilotinib influences phenotype and function of monocyte derived human dendritic cells. AB - In chronic myeloid leukemia (CML), the translocation t(9;22) results in the fusion protein BCR-ABL (breakpoint cluster region-abelson murine leukemia), a tyrosine kinase mediating oncogenic signaling which is successfully targeted by treatment with BCR-ABL inhibitors like imatinib. However, BCR-ABL inhibitors may also affect antitumor immunity. For instance, it was reported that imatinib impairs the function of dendritic cells (DCs) that play a central role in initiating and sustaining T cell responses. Meanwhile, second generation BCR-ABL inhibitors like nilotinib, which inhibits BCR-ABL with enhanced potency have become standard of treatment, at least in patients with BCR-ABL kinase domain mutations. In this study we analyzed the influence of therapeutic concentrations of nilotinib on human monocyte-derived DCs and compared its effects to imatinib. We found that both tyrosine kinase inhibitors (TKI) comparably and significantly impaired differentiation of monocytes to DCs as revealed by curtated downregulation of CD14 and reduced upregulation of CD1a and CD83. This was only partially restored after withdrawal of the TKI. Moreover, both TKI significantly reduced activation-induced IL-12p70 and C-C motif chemokine ligand (CCL) 3 secretion, while divergent TKI effects for CCL2 and CCL5 were observed. In contrast, only nilotinib significantly impaired the migratory capacity of DCs and their capacity to induce T-cell immune responses in MLRs. Our results indicate that imatinib and nilotinib may differ significantly with regard to their influence on antitumor immunity. Thus, for future combinatory approaches and particularly stop studies in CML treatment, choice of the most suitable BCR-ABL inhibitor requires careful consideration. PMID- 29468364 TI - Antitumor in situ vaccination effect of TNFalpha and IL-12 plasmid DNA electrotransfer in a murine melanoma model. AB - Gene electrotransfer (GET) is one of the most efficient non-viral gene therapy approaches for the localized transfer of multiple genes into tumors in vivo; therefore, it is especially promising for delivering different cytokines that are toxic if administered systemically. In this study, we used concomitant intratumoral GET of two cytokines: tumor necrosis factor alpha (TNFalpha), a potent cytotoxic cytokine to induce in situ vaccination, and interleukin 12 (IL 12), an immunostimulatory cytokine to boost the primed local immune response into a systemic one. After performing GET in murine melanoma tumors, both TNFalpha and IL-12 mRNA levels were significantly increased, which resulted in a pronounced delay in tumor growth of 27 days and a prolonged survival time of mice. An antitumor immune response was confirmed by extensive infiltration of immune cells in the tumor site, and expansion of the effector immune cells in the sentinel lymph nodes. Furthermore, the effect of in situ vaccination was indicated by the presence of vitiligo localized to the treatment area and resistance of the mice to secondary challenge with tumor cells. Intratumoral GET of two cytokines, one for in situ vaccination and one for an immune boost, proved feasible and effective in eliciting a potent and durable antitumor response; therefore, further studies of this approach are warranted. PMID- 29468365 TI - Testicular torsion with preserved flow: key sonographic features and value-added approach to diagnosis. AB - Testicular sonography has contributed greatly to the preoperative diagnosis of testicular torsion in the pediatric patient and is the mainstay for evaluation of acute scrotal pain. Despite its high sensitivity and specificity, both false negative and false-positive findings occur. Presence of documented Doppler flow within the testis might be a dissuading factor for surgical exploration with resultant testicular loss in the false-negative cases. Our goal is to illustrate key sonographic features in the spectrum of testicular torsion with preserved testicular flow, and to describe how to differentiate testicular torsion from epididymitis in order to avoid the under-diagnosis of testicular torsion. We simplify the anatomy of the bell clapper testis. We also describe our sonographic protocol for testicular torsion and share valuable tips from our approach to challenging cases. PMID- 29468366 TI - Utility of CT classifications to predict unfavorable outcomes in children with acute pancreatitis. AB - BACKGROUND: Computed tomography (CT) is useful for the diagnosis of local complications in children with acute pancreatitis but its role as a prognostic tool remains controversial. OBJECTIVE: To establish the correlation between the CT Severity Index and the Revised Atlanta Classification regarding unfavorable outcomes such as severe acute pancreatitis and need for Pediatric Special Care Unit attention in children with acute pancreatitis. MATERIALS AND METHODS: We conducted a retrospective and concordance cohort study in which we obtained abdominal CT scans from 30 patients ages 0 to 18 years with acute pancreatitis. Two pediatric radiologists interpreted the results using the CT Severity Index and the Revised Atlanta Classification. The kappa coefficient was determined for each scale. The association among severe acute pancreatitis, need for admission to the Pediatric Special Care Unit and CT systems were established using chi square or Mann-Whitney U tests. The best CT Severity Index value to predict the need for admission to the Pediatric Special Care Unit was estimated through a receiver operating characteristic (ROC) curve. RESULTS: Mean CT Severity Index was 5.1+/-2.8 (mean +/- standard deviation on a scale of 0 to 10) for the severe acute pancreatitis group vs. 3.8+/-2.7 for the mild acute pancreatitis group (P=0.230). The CT Severity Index for the children who were not hospitalized at the Pediatric Special Care Unit was 2.2+/-2.2 vs. 5.6+/-2.4 for the group hospitalized at the Pediatric Special Care Unit (P=0.001). Only parenchymal necrosis >30% was associated with severe acute pancreatitis (P=0.021). A CT Severity Index >=3 has a sensitivity of 89% and specificity of 72% to predict need for admission to the Pediatric Special Care Unit. None of the Revised Atlanta Classification categories was associated with severe acute pancreatitis or admission to the Pediatric Special Care Unit. CONCLUSION: A CT Severity Index >=3 in children with acute pancreatitis who require CT assessment based on clinical criteria is associated with the need for admission to the Pediatric Special Care Unit. We found that pancreatic necrosis greater than 30% is the only tomographic parameter related to severe acute pancreatitis. New studies with a greater sample size are necessary to confirm this result. PMID- 29468367 TI - Diagnosis, treatment and outcome of hepatic venous outflow obstruction in paediatric liver transplantation: 24-year experience at a single centre. AB - BACKGROUND: Hepatic venous outflow obstruction after paediatric liver transplantation is an unusual but critical complication. OBJECTIVES: To review the incidence, diagnosis and therapeutic modalities of hepatic venous outflow obstruction from a large national liver transplant unit. MATERIALS AND METHODS: During the period from October 1992 to March 2016, 917 liver transplant procedures were performed with all types of grafts in 792 children. Transplants suspected to have early or delayed venous outflow obstruction were confirmed by percutaneous venography or surgical revision findings. Therapeutic intervention, recurrence and outcome were evaluated. RESULTS: Twenty-six of 792 children (3.3%) experienced post-transplant hepatic venous outflow obstruction. These patients had been diagnosed from 1 day to 8.75 years after transplantation. Six occurred during the early post-transplant period; in three of them, the graft was lost. Seventeen patients were initially treated by balloon angioplasty with success; 11 of these experienced recurrences. Four stents were implanted; one was complicated by definitive occlusion. Three of the five surgical revisions were successful. The initial stenosis involved the inferior vena cava in 10 grafts, in isolation or associated with hepatic vein involvement. Mean follow-up was 79 months after transplantation. Eight grafts were lost. CONCLUSION: Acute postoperative hepatic venous outflow obstruction was associated with poor prognosis. Diagnostic venography should be performed if there is any suspicion of venous outflow obstruction, even if first-line examinations are normal. Stenosis frequently involved the inferior vena cava. Angioplasty was a safe and efficient treatment for venous outflow obstruction despite frequent recurrence. PMID- 29468368 TI - Transitions of Developmental Trajectories of Depressive Symptoms Between Junior and Senior High School Among Youths in Taiwan: Linkages to Symptoms in Young Adulthood. AB - We investigated the heterogeneous developmental trajectories of depressive symptoms in junior and senior high school, the transitions to different trajectories after entering senior high school, and the linkages to the development of depressive symptoms in early adulthood among Taiwanese adolescents. An eight-wave longitudinal data set was analyzed, including 2687 Taiwanese adolescents (51.2% boys, M age = 14.3 at first wave). Using a manual three-step latent transition growth mixture model, we found that a three-class solution fit the data for both junior high school (termed high-improving, cumulative, and JS-low-stable) and senior high school period (termed heightening, moderate-stable, and HS-low-stable). The depressive symptoms of most individuals maintained at a low level (i.e., low-stable) from adolescence to early adulthood; however, nearly a quarter of the adolescents reported depressive symptoms that were moderately or highly severe in senior high school and beyond. More than 30% of the participants experienced transitioning into a different developmental trajectory between junior and senior high school. When perceiving a higher level of paternal behavioral control, adolescents categorized in the high-improving class in junior high school would have a higher chance to transition to the moderate-stable class than to HS-low-stable class in senior high school. Adolescent boys and girls did not differ in the probability of transitioning between trajectories across junior and senior high school. However, a clear and consistent pattern of symptoms between late adolescence and early adulthood was not observed. These results help elucidate the heterogeneity and fluidity associated with the development of depressive symptoms between early adolescence and early adulthood in light of school transition among youths in Taiwan.

AB - Seemingly ever improving medical technology and techniques portend the possibility of prenatally enhancing otherwise healthy, normal children-seamlessly enhancing or adding to a child's natural abilities and characteristics. Though parents normally engage in enhancing children, i.e., child rearing, these technologies present radically new possibilities. This sort of enhancement, I argue, is morally problematic for the parent: the expectations of the enhancing parent necessarily conflict with attitudes of acceptance that moral parenting requires. Attitudes of acceptance necessitate that parents are open to the essentially-individual choices of the child that will determine the kind of person he or she becomes. However, the intentional act of enhancing contradicts this openness by setting expectations on who the child becomes. Because of this, there is strong moral weight against parents' prenatally enhancing their children. PMID- 29468369 TI - Role of endoplasmic reticulum stress in 12/15-lipoxygenase-induced retinal microvascular dysfunction in a mouse model of diabetic retinopathy. AB - AIMS/HYPOTHESIS: Our earlier studies have established the role of 12/15 lipoxygenase (LO) in mediating the inflammatory reaction in diabetic retinopathy. However, the exact mechanism is still unclear. The goal of the current study was to identify the potential role of endoplasmic reticulum (ER) stress as a major cellular stress response in the 12/15-LO-induced retinal changes in diabetic retinopathy. METHODS: We used in vivo and in vitro approaches. For in vivo studies, experimental diabetes was induced in wild-type (WT) mice and 12/15-Lo (also known as Alox15) knockout mice (12/15-Lo-/-); ER stress was then evaluated after 12-14 weeks of diabetes. We also tested the effect of intravitreal injection of 12-hydroxyeicosatetraenoic acid (HETE) on retinal ER stress in WT mice and in mice lacking the catalytic subunit of NADPH oxidase, encoded by Nox2 (also known as Cybb) (Nox2-/- mice). In vitro studies were performed using human retinal endothelial cells (HRECs) treated with 15-HETE (0.1 MUmol/l) or vehicle, with or without ER stress or NADPH oxidase inhibitors. This was followed by evaluation of ER stress response, NADPH oxidase expression/activity and the levels of phosphorylated vascular endothelial growth factor receptor-2 (p-VEGFR2) by western blotting and immunoprecipitation assays. Moreover, real-time imaging of intracellular calcium (Ca2+) release in HRECs treated with or without 15-HETE was performed using confocal microscopy. RESULTS: Deletion of 12/15-Lo significantly attenuated diabetes-induced ER stress in mouse retina. In vitro, 15 HETE upregulated ER stress markers such as phosphorylated RNA-dependent protein kinase-like ER-regulated kinase (p-PERK), activating transcription factor 6 (ATF6) and protein disulfide isomerase (PDI) in HRECs. Inhibition of ER stress reduced 15-HETE-induced-leucocyte adhesion, VEGFR2 phosphorylation and NADPH oxidase expression/activity. However, inhibition of NADPH oxidase or deletion of Nox2 had no effect on ER stress induced by the 12/15-LO-derived metabolites both in vitro and in vivo. We also found that 15-HETE increases the intracellular calcium in HRECs. CONCLUSIONS/INTERPRETATION: ER stress contributes to 12/15-LO induced retinal inflammation in diabetic retinopathy via activation of NADPH oxidase and VEGFR2. Perturbation of calcium homeostasis in the retina might also play a role in linking 12/15-LO to retinal ER stress and subsequent microvascular dysfunction in diabetic retinopathy.

AB - AIMS: This study aimed to examine the relationships between gastroparesis symptom severity, illness perceptions, coping styles, quality of life (QoL), and psychological distress in patients with gastroparesis, guided by the common sense model. METHODS: One hundred and seventy-nine adults with gastroparesis (165 females, 14 males; mean age 41.82 years) completed an online questionnaire. The Gastroparesis Cardinal Symptom Index was used to measure gastroparesis symptom severity, QoL was explored using the PAGI-QOL, illness perceptions were measured using the Brief Illness Perception Questionnaire, the Carver Brief COPE scale assessed coping styles, and psychological distress was investigated using the DASS21. RESULTS: Structural equation modeling resulted in a final model with excellent fit. Gastroparesis symptom severity directly influenced illness perceptions (beta = .52, p < .001) and QoL (beta = .30, p < .001). Illness perceptions directly influenced maladaptive coping (beta = - .64, p < .001), psychological distress (beta = - .32, p < .001), and QoL (beta = .30, p = .01). Maladaptive coping directly influenced psychological distress (beta = .62, p < .001), which in turn had a direct influence on QoL (beta = - .38, p < .001). CONCLUSIONS: The final model showed that the influence of gastroparesis symptom severity on psychological distress was fully mediated by illness perceptions, while the influence on QoL was partially mediated by illness perceptions. The study provides guidance for the development of psychological interventions targeted toward improving mediating psychological factors. PMID- 29468374 TI - Fecal Calprotectin in Assessing Endoscopic and Histological Remission in Patients with Ulcerative Colitis. AB - BACKGROUND: Persistent active endoscopic and histological inflammation is associated with poorer outcomes in ulcerative colitis (UC). Fecal calprotectin is a surrogate marker of endoscopic and histological remission. AIMS: To confirm the correlation between fecal calprotectin and endoscopic or histological disease activity and to define the optimal cutoff value to detect endoscopic and histological remission. METHODS: From a prospectively maintained database, we analyzed 61 UC patients who had fecal calprotectin measurement and endoscopy performed within 1 month. Endoscopic activity was graded using the Mayo endoscopic subscore (MES). Histological remission was defined as normal histology or quiescent histological activity. RESULTS: Eighteen patients (29.5%) and five patients (8.1%) had endoscopic remission defined as MES <= 1 or MES = 0, respectively. We observed a significantly lower median level of fecal calprotectin in patients with endoscopic remission than those with endoscopic activity for both definition of endoscopic remission, i.e., MES <= 1 (158 vs 490 ug/g, p = 0.0005) or MES = 0 (94 vs 414 ug/g, p = 0.013). Seven patients (11.5%) were in histological remission. They had a lower median level of fecal calprotectin than those with active histological inflammation (107 vs 416 ug/g, p = 0.016). Using a ROC curve, fecal calprotectin < 250 ug/g predicted endoscopic remission (MES <= 1) with a sensitivity of 67% and specificity of 77%, while fecal calprotectin < 200 ug/g predicted histological remission with a sensitivity of 71% and specificity of 76%. CONCLUSION: Fecal calprotectin level correlated with both endoscopic activity and histological activity and is a reliable biomarker in assessing mucosal healing in UC.

PMID- 29468376 TI - Gastric Per Oral Endoscopic Myotomy (G-POEM) for the Treatment of Refractory Gastroparesis: Early Experience. AB - BACKGROUND: Gastric per oral endoscopic myotomy (G-POEM) of the pylorus is a technique that is recently being used to treat gastroparesis. Our aim was to report our experience in performing G-POEM for refractory gastroparesis of different etiologies and determine symptom improvement. METHODS: Thirteen patients undergoing G-POEM are reported. Pre- and post-procedure gastric emptying study (GES) and PAGI-SYM for symptom severity were obtained. Patients underwent G POEM by creating a submucosal tunnel starting in the greater curvature of the distal antrum and extending it to the beginning of the duodenal bulb, followed by a full thickness pyloromyotomy. RESULTS: All 13 gastroparesis patients successfully underwent G-POEM (one diabetic [DGp], four idiopathic [IGp], eight postsurgical [PSGp]). Postsurgical patients included 4 s/p esophagectomy for esophageal cancer, 3 s/p Nissen fundoplication, and 1 s/p esophagectomy for achalasia. There were no procedure-related side effects. Of 11 patients completing follow-up questionnaires, eight were improved subjectively (four patients reported considerably better, four patients somewhat better, one unchanged, and two worse). Individual symptom severity scores tended to improve, particularly vomiting, retching, and loss of appetite. Of six patients that had post-G-POEM GES; GES improved in four, unchanged in one, and worsened in one). CONCLUSIONS: G-POEM for treatment of refractory gastroparesis appears to be a feasible and safe technique that can be successfully performed in patients with a variety of etiologies including different types of postsurgical gastroparesis. Our initial experience suggests that the majority of patients report some improvement in symptoms, particularly symptoms of vomiting, retching, and loss of appetite. Further experience is needed to determine the efficacy and safety of G POEM and predict those who best respond to this treatment. PMID- 29468378 TI - Achalasia Patients Are at Nutritional Risk Regardless of Presenting Weight Category. AB - BACKGROUND: Achalasia is an esophageal motor disorder that leads to swallowing dysfunction and weight loss. Nutritional risk in achalasia patients is not well defined. AIMS: The aims of this study were to define baseline body mass index (BMI), changes in weight, and nutritional risk over time in a large cohort of achalasia patients. METHODS: This was a retrospective cohort study of achalasia patients at a tertiary care center with documented BMI, symptom severity as per Eckardt score, and nutritional risk assessment as per the Malnutrition Universal Screening Tool, which considers BMI, degree of recent weight loss, and acuity of disease. RESULTS: Among the 337 patients presenting for achalasia management, 179 had confirmed disease. Upon presentation 69.8% of patients were classified as overweight or obese. Using the Malnutrition Universal Screening Tool, we found 50% of patients to be at moderate or high risk for malnutrition at presentation. Eckardt score (OR 1.15, 95% CI 1.05-1.26), duration of disease (OR for each additional month 1.04, 95% CI 1.01-1.08), and female gender (OR 1.76, 95% CI 1.02 3.03) were independent predictors of increased risk for malnutrition. Nutrition risk score decreased after therapy in 93.3% of patients. CONCLUSIONS: Despite a high prevalence of overweight and obese status in achalasia patients, many are at risk of developing nutritional complications secondary to rapid weight loss. This risk frequently resolves post-treatment. Regardless of baseline BMI, we recommend all patients undergo nutritional assessment to identify high-risk patients who may benefit from dietary intervention and expedited therapy. PMID- 29468377 TI - Adenoma Detection Rate in Asymptomatic Patients with Positive Fecal Immunochemical Tests. AB - BACKGROUND AND AIMS: The adenoma detection rate (ADR) is a powerful measure of screening colonoscopy quality. Patients who undergo colonoscopy for the evaluation of a positive fecal immunochemical test (FIT) have increased prevalence of colorectal neoplasia, but it is not known whether separate quality benchmarks are required. The aim of this study was to compare the conventional ADR to the ADR of colonoscopies performed for the evaluation of positive FIT, in asymptomatic average-risk patients. METHODS: Patients >= 50 years old who underwent colonoscopy for the evaluation of a positive FIT between January 1, 2013, and July 31, 2014, at a tertiary Veterans Affairs Medical Center were identified. FIT performed for any indication other than average-risk screening was excluded. The comparison group included average-risk patients >= 50 years old undergoing screening colonoscopy during the same time frame. The two groups were compared for ADR, advanced neoplasm [adenoma >= 10 mm, tubulovillous, high-grade dysplasia, CRC, sessile serrated polyp (SSP) >= 10 mm], CRC, and SSP detection after propensity score adjustment using a logistic regression model adjusted for endoscopist. RESULTS: There were 207 patients in the FIT group and 601 in the screening colonoscopy comparison group. After propensity score adjustment, ADR (72.9 vs. 50.0%, p = 0.003), number of adenomas per colonoscopy (3.3 +/- 3.6 vs. 1.4 +/- 2.3, p = 0.033), and advanced neoplasm detection rate (32.4 vs. 11.0%, p < 0.0001) were significantly higher in the FIT group. There were no significant differences in the number of CRC and the SSP detection rate. CONCLUSIONS: In this cohort of average-risk Veterans, the ADR of colonoscopies performed for the evaluation of a positive FIT was higher than the ADR of screening colonoscopies. Patients with a positive FIT also had significantly more adenomas per colonoscopy and advanced neoplasms. These findings suggest that the quality of colonoscopies performed for a positive FIT is insufficiently assessed by the conventional ADR and requires additional quality metrics.

PMID- 29468380 TI - Guidelines examination of victims of sexual assault harmonization of forensic and medico-legal examination of persons. AB - Sexual assault is a complex situation with medical, psychological, and legal aspects. Forensic experts play a major role in terms of forensic and gynecological medical examination and evidence collection in order to maintain the chain of custody. Victims should be examined by a specially trained medico legal examiner in order to avoid multiple examinations in the surroundings that do not meet minimum health standards. The evolution and treatment of sexual assault victims are time-intensive and should optimally be provided by a team that includes a forensic medical doctor. These guidelines will be of interest to forensic medical doctors who will have responsibility for the examination and assessment of victims of sexual violence and can be used as a day-to-day service document and/or a guide to develop health service for victims of sexual violence.

PMID- 29468381 TI - Massively parallel sequencing-enabled mixture analysis of mitochondrial DNA samples. AB - The mitochondrial genome has a number of characteristics that provide useful information to forensic investigations. Massively parallel sequencing (MPS) technologies offer improvements to the quantitative analysis of the mitochondrial genome, specifically the interpretation of mixed mitochondrial samples. Two person mixtures with nuclear DNA ratios of 1:1, 5:1, 10:1, and 20:1 of individuals from different and similar phylogenetic backgrounds and three-person mixtures with nuclear DNA ratios of 1:1:1 and 5:1:1 were prepared using the Precision ID mtDNA Whole Genome Panel and Ion Chef, and sequenced on the Ion PGM or Ion S5 sequencer (Thermo Fisher Scientific, Waltham, MA, USA). These data were used to evaluate whether and to what degree MPS mixtures could be deconvolved. Analysis was effective in identifying the major contributor in each instance, while SNPs from the minor contributor's haplotype only were identified in the 1:1, 5:1, and 10:1 two-person mixtures. While the major contributor was identified from the 5:1:1 mixture, analysis of the three-person mixtures was more complex, and the mixed haplotypes could not be completely parsed. These results indicate that mixed mitochondrial DNA samples may be interpreted with the use of MPS technologies.

AB - BACKGROUND: The effect of levocarnitine supplementation has not been evaluated in children with dilated cardiomyopathy (DCM). OBJECTIVE: The aim of this study was to explore the effect of oral levocarnitine supplementation in pediatric patients with DCM. METHODS: Twenty-nine children with DCM (17 male, 12 female, aged 1 month to 13 years) were divided into two groups according to a simple randomization: control group (n = 10) and experimental group (n = 19). All children were given oral hydrochlorothiazide, enalapril, and spironolactone; additionally, patients with cardiac function of NYHA grade IV were given oral digoxin, and patients with intractable heart failure were given intravenous dopamine and dobutamine. When cardiac function was restored to NYHA grade II-III, patients were given oral metoprolol. Patients in the experimental group received add-on treatment with oral levocarnitine solution (50-100 mg/kg/day). Patients were followed up at 1, 3, 6 and 12 months. Left ventricular ejection fraction (EF), short axis shortening (FS), and left atrium (LA) and left ventricle (LV) diameters were measured at different times during the follow-up. RESULTS: The children with DCM were followed up for 1 year. Cardiac function was significantly improved in the experimental group compared with the control group. Specifically, the EF and FS were increased (p < 0.05), the LA and LV diameters were reduced (p < 0.05), and the EF was increased more significantly in the experimental group than in the control group (p < 0.05). CONCLUSIONS: Oral levocarnitine solution appeared to enhance the therapeutic efficacy of conventional therapy in children with DCM. PMID- 29468384 TI - Redirection of neuroblast migration from the rostral migratory stream into a lesion in the prefrontal cortex of adult rats. AB - Clinical treatment of structural brain damage today is largely limited to symptomatic approaches and the avoidance of secondary injury. However, neuronal precursor cells are constantly produced within specified regions of the mammalian brain throughout life. Here we evaluate the potential of the known chemoattractive properties of the glycoprotein laminin on neuroblasts to relocate the cells into damaged brain areas. Injection of a thin laminin tract, leading from the rostral migratory stream to an excitotoxic lesion within the medial prefrontal cortex of rats, enabled neuroblasts to migrate away from their physiological route towards the olfactory bulb into the lesion site. Once they reached the damaged tissue, they migrated further in a non-uniform orientation within the lesion. Furthermore, our data indicate that the process of diverted migration is still active 6 weeks after the treatment and that at least some of the neuroblasts are capable of maturing into adult neurons. PMID- 29468385 TI - Comments on Marken and Shaffer: The power law of movement: an example of a behavioral illusion. AB - Many researchers who have studied movements along curved paths, under a variety of conditions, by different organisms, mostly human but a couple with non-human organisms, have found a consistent form of relation between the tangential (along track) instantaneous velocity V and the local radius of curvature R. The consistent relation is that V ~ cR k , where k is a constant less than unity, often near 0.33 but sometimes far from 0.33, and c is a proportionality constant appropriate to the organism and the situation (see Zago, Matic, Flash, et al. (2017) for many examples in which the power law holds with widely varying values of the power, as well as cases of simple systems for which everything can be calculated exactly and in which the power law fails badly). Marken and Shaffer (Exp Brain Res 235:1835-1842; 2017), following a challenge by Gomez-Marin to see whether it is possible to use Perceptual Control Theory (Powers 1973/2005) to explain the power law results (Alex Gomez-Marin posting to CSGnet@lists.illinois.edu 2016.05.03), claim to have found a mathematical argument that proves the true exponent of the power relating velocity and radius of curvature always to be 1/3. They say that deviations from this value occur because researchers have omitted a critical correction "cross-product" factor that the authors label "D". This note questions the logic of the analysis offered by Marken and Shaffer, and argues that even had the analysis been correct, it would not affect future research into the reasons why and when the power law is observed and the circumstances that determine the value of the power found when it is observed. PMID- 29468386 TI - Muscle spindle thixotropy affects force perception through afferent-induced facilitation of the motor pathways as revealed by the Kohnstamm effect. AB - This study was designed to explore the effects of intrafusal thixotropy, a property affecting muscle spindle sensitivity, on the sense of force. For this purpose, psychophysical measurements of force perception were performed using an isometric force matching paradigm of elbow flexors consisting of matching different force magnitudes (5, 10 and 20% of subjects' maximal voluntary force). We investigated participants' capacity to match these forces after their indicator arm had undergone voluntary isometric conditioning contractions known to alter spindle thixotropy, i.e., contractions performed at long ('hold long') or short muscle lengths ('hold short'). In parallel, their reference arm was conditioned at the intermediate muscle length ('hold-test') at which the matchings were performed. The thixotropy hypothesis predicts that estimation errors should only be observed at low force levels (up to 10% of the maximal voluntary force) with overestimation of the forces produced following 'hold short' conditioning and underestimation following 'hold long' conditioning. We found the complete opposite, especially following 'hold-short' conditioning where subjects underestimated the force they generated with similar relative error magnitudes across force levels. In a second experiment, we tested the hypothesis that estimation errors depended on the degree of afferent-induced facilitation using the Kohnstamm phenomenon as a probe of motor pathway excitability. Because the stronger post-effects were observed following 'hold-short' conditioning, it appears that the conditioning-induced excitation of spindle afferents leads to force misjudgments by introducing a decoupling between the central effort and the cortical motor outputs. PMID- 29468387 TI - Assessing the equivalence of Web-based and paper-and-pencil questionnaires using differential item and test functioning (DIF and DTF) analysis: a case of the Four Dimensional Symptom Questionnaire (4DSQ). AB - PURPOSE: Many paper-and-pencil (P&P) questionnaires have been migrated to electronic platforms. Differential item and test functioning (DIF and DTF) analysis constitutes a superior research design to assess measurement equivalence across modes of administration. The purpose of this study was to demonstrate an item response theory (IRT)-based DIF and DTF analysis to assess the measurement equivalence of a Web-based version and the original P&P format of the Four Dimensional Symptom Questionnaire (4DSQ), measuring distress, depression, anxiety, and somatization. METHODS: The P&P group (n = 2031) and the Web group (n = 958) consisted of primary care psychology clients. Unidimensionality and local independence of the 4DSQ scales were examined using IRT and Yen's Q3. Bifactor modeling was used to assess the scales' essential unidimensionality. Measurement equivalence was assessed using IRT-based DIF analysis using a 3-stage approach: linking on the latent mean and variance, selection of anchor items, and DIF testing using the Wald test. DTF was evaluated by comparing expected scale scores as a function of the latent trait. RESULTS: The 4DSQ scales proved to be essentially unidimensional in both modalities. Five items, belonging to the distress and somatization scales, displayed small amounts of DIF. DTF analysis revealed that the impact of DIF on the scale level was negligible. CONCLUSIONS: IRT-based DIF and DTF analysis is demonstrated as a way to assess the equivalence of Web-based and P&P questionnaire modalities. Data obtained with the Web-based 4DSQ are equivalent to data obtained with the P&P version. PMID- 29468388 TI - Sorption of benzene derivatives onto a humic acid-zeolitic tuff adduct. AB - The sorption of some benzene derivatives: o-xylene, toluene, phenol, benzyl alcohol, resorcinol and hydroquinone onto a zeolitic tuff-humic acid adduct (PCT ImHA) was analysed by batch technique at 25 degrees C and neutral pH. PCT-ImHA was prepared by binding leonardite-extracted humic acids (HA) to a zeolitic tuff sample rich in phillipsite and chabazite and enriched with Ca2+ by cation exchange (Ca-PCT). The HA calcium salts were gently mixed with wet Ca-PCT; then, the mixture was heated at 330 degrees C for 1.5 h. An adduct with almost 2% of HA was obtained. The experimental data were well fitted by the Langmuir adsorption isotherm and showed that saturation capacity (qMax) increased with the octanol-water repartition coefficient (KO-W). The comparison with previous data on sorption onto immobilised HA highlights that qMax values for PCT-ImHA are far higher than the sum of the contributions of the two separate components. PMID- 29468389 TI - The '333' integrated strategy for effective pollution control and its application to the heavily polluted Jialu River in north China. AB - In this study, an integrated approach named the '333' strategy was applied to pollution control in the Jialu River, in northern China, which is heavily burdened with anthropogenic pollution. Due to a deficiency of the natural ecological inflow, the Jialu River receives predominantly industrial and municipal effluent. The '333' strategy is composed of three steps of pollution control including industrial point-source pollution control, advanced treatment of municipal wastewater, and ecological restoration; three increased stringency emission standards; and three stages of reclamation. Phase 1 of the '333' strategy focuses on industrial point-source pollution control; phase 2 aims to harness municipal wastewater and minimize sewage effluents using novel techniques for advanced water purification; phase 3 of the '333' strategy focuses on the further purification of effluents flowing into Jialu River with the employment of an engineering-based ecological restoration project. The application of the '333' strategy resulted in the development of novel techniques for water purification including modified magnetic resins (NDMP resin), a two-stage internal circulation anaerobic reactor (IC reactor) and an ecological restoration system. The results indicate that water quality in the river was significantly improved, with increased concentrations of dissolved oxygen (DO), as well as reduction of COD by 42.8% and NH3-N by 61.4%. In addition, it was observed that the total population of phytoplankton in treated river water notably increased from only one prior to restoration to 8 following restoration. This system also provides a tool for pollution control of other similar industrial and anthropogenic source polluted rivers. PMID- 29468390 TI - Impacts of sewer deposits on the urban river sediment after rainy season and bioremediation of polluted sediment. AB - Impacts of deposits discharged from a municipal pipe on urban river sediment were investigated in the Hucang River in Tianjin, China. At the outlet of the pump station, the average concentrations of total nitrogen (TN), total phosphorus (TP), and total organic carbon (TOC) in the sediment increased sharply from 2390, 799, and 14,600 mg/kg to 6500, 3700, and 153,000 mg/kg, respectively, and remained stable at high level after the rainy season. A portion of pollutants would migrate along the river, and the concentration was usually in a negative relationship with the distance. The average Shannon-Wiener value on the upstream section was higher than those on the downstream sections. This revealed that the deposits discharged decreased the bacterial diversity in the sediment, and high concentrations of pollutants may markedly change the bacterial community structure in the sediment. To reduce the pollution of the urban river after rainy season, four kinds of microbial consortiums A (Zhangda), B (Aiersi), C (Qinghe), and D (Inpipe) were applied to bioremediate the polluted sediment in lab scale. Bioaugmentation with microbial consortium A showed good performance on the bioremediation of the polluted sediment. The average removal efficiency of TN, TP, and organic matter reached 35.5, 43.7, and 39.1%, respectively, after 22 days of treatment. Moreover, the bacterial evenness and diversity in the sediment markedly increased, indicating that the microbial environment was more favourable after bioaugmentation and sustainable development would be guaranteed. This study improves our understanding of the impacts of deposits discharged from a stormwater drain system on urban river sediment, and explores the effectiveness of bioaugmentation for the bioremediation of polluted sediment, which will provide the basis of sewer deposit pollution control. PMID- 29468391 TI - Intercropping efficiency of four arsenic hyperaccumulator Pteris vittata populations as intercrops with Morus alba. AB - Soils that are slightly or moderately contaminated with arsenic (As) can be safely utilized by intercropping As hyperaccumulator Pteris vittata with cash crops. Introducing hyperaccumulators into crop planting systems results in the alleviation of the adverse effects of As and competition effect for resources. The balance between these two effects determines intercropping efficiency. The effect of using different hyperaccumulator populations on such balance is the focus of this study. Through a tank experiment, four P. vittata populations were compared on the basis of their intercropping efficiencies and physiological and morphological characteristics. The evaluation of the intercropping efficiency of P. vittata was mainly based on the capabilities of the species to promote growth and decrease As concentrations in intercropped Morus alba. Two populations of P. vittata were appropriate for intercropping with M. alba, with the alleviation effect of As harm as the main effect on the intercropping system. These populations showed extensive root overlap with M. alba and efficient uptake of bioavailable As, thus depleting As in the rhizosphere and lowering As risk. After different P. vittata populations were used, varied interspecific interactions were observed. Root overlap and aboveground morphological parameters are the key factors determining intercropping efficiency among P. vittata populations. PMID- 29468392 TI - Hydrogen sulfide regulates the levels of key metabolites and antioxidant defense system to counteract oxidative stress in pepper (Capsicum annuum L.) plants exposed to high zinc regime. AB - In the present experiment, we aimed to test the impact of hydrogen sulfide (H2S) on growth, key oxidant such as hydrogen peroxide, mineral elements, and antioxidative defense in Capia-type red sweet pepper (Capsicum annuum L.) plants subjected to high concentration of zinc (Zn). A factorial experiment was designed with two Zn levels (0.05 and 0.5 mM) and 0.2 mM sodium hydrosulfide (NaHS) as a donor of H2S supplied in combination plus nutrient solution through the root zone. High level of Zn led to reduce dry mass, chlorophyll pigments, fruit yield, leaf maximum fluorescence, and relative water content, but enhanced endogenous hydrogen peroxide (H2O2), free proline, malondialdehyde (MDA), electrolyte leakage (EL), H2S, as well as the activities of peroxidase (POD), catalase (CAT), and superoxide dismutase (SOD) enzymes. Exogenously applied NaHS significantly enhanced plant growth, fruit yield, water status, the levels of H2S and proline as well as the activities of different antioxidant enzymes, while it significantly suppressed EL, MDA, and H2O2 contents in the pepper plants receiving low level Zn. NaHS application to the control plants did not significantly change all these parameters tested except the dry matter which increased significantly. High Zn regime led to increase intrinsic Zn levels in the leaves and roots, but it lowered leaf nitrogen (N), phosphorus (P), and iron (Fe) concentrations. However, NaHS reduces the Zn conc. and enhances Fe and N in leaf and root organs. It can be concluded that NaHS can mitigate the harmful effects of Zn on plant growth particularly by lowering the concentrations of H2O2, Zn, EL, and MDA, and enhancing the activities of enzymatic antioxidants and levels of essential nutrients in pepper plants. PMID- 29468394 TI - Emission and performance analysis on the effect of exhaust gas recirculation in alcohol-biodiesel aspirated research diesel engine. AB - In this study, the effect of blending pentanol to biodiesel derived from mahua oil on emissions and performance pattern of a diesel engine under exhaust gas recirculation (EGR) mode was examined and compared with diesel. The purpose of this study is to improve the feasibility of employing biofuels as a potential alternative in an unmodified diesel engine. Two pentanol-biodiesel blends denoted as MOBD90P10 and MOBD80P20 which matches to 10 and 20 vol% of pentanol in biodiesel, respectively, were used as fuel in research engine at 10 and 20% EGR rates. Pentanol is chosen as a higher alcohol owing to its improved in-built properties than the other first-generation alcohols such as ethanol or methanol. Experimental results show that the pentanol and biodiesel blends (MOBD90P10 and MOBD80P20) have slightly higher brake thermal efficiency (0.2-0.4%) and lower brake-specific fuel consumption (0.6 to 1.1%) than that of neat biodiesel (MOBD100) at all engine loads. Nitrogen oxide (NOx) emission and smoke emission are reduced by 3.3-3.9 and 5.1-6.4% for pentanol and biodiesel blends compared to neat biodiesel. Introduction of pentanol to biodiesel reduces the unburned hydrocarbon (2.1-3.6%) and carbon monoxide emissions (3.1-4.2%) considerably. In addition, at 20% EGR rate, smoke, NOX emissions, and BTE drop by 7.8, 5.1, and 4.4% respectively. However, CO, HC emissions, and BSFC increased by 2.1, 2.8, and 3.8%, respectively, when compared to 0% EGR rate. PMID- 29468393 TI - Growth performance, metal accumulation and biochemical responses of Palak (Beta vulgaris L. var. Allgreen H-1) grown on soil amended with sewage sludge-fly ash mixtures. AB - Agricultural utilization of sewage sludge (SS) and fly ash (FA) has become both, a common practice and an alternative disposal method for these wastes all around the world. The present study was conducted to assess the effect and viability of co-application of SS and FA (SLASH) in four mixing ratios denoted as A [4 (SS): 1(FA)], B [4 (SS): 2 (FA)], C [4 (SS): 3 (FA)] and D [4 (SS): 4(FA)] at three application rates viz. 20, 40 and 60% (w/w) with agricultural soil on biochemical, physiological and growth response of Palak (Beta vulgaris L. var. Allgreen H-1), a commonly used green leafy vegetable. SLASH amendment modified the physico-chemical properties of soil and increased the concentration of heavy metals (Cd, Cr, Cu, Fe, Ni, Pb, Zn) in soil and plant parts however, within the Indian permissible limit except for Cr, Cd and Zn in shoot. Experimental results revealed decrease in morphological and growth parameters such as root and shoot length, leaf area, root, shoot biomass etc. Lipid peroxidation, ascorbic acid, proline and protein content increased however, total chlorophyll and carotenoid content decreased indicating towards heavy metal stress induced biochemical and physiological response in Palak plants. Significant increase in yield was seen in some of the treatments viz. three mixing ratios B, C and D, with maximum increment shown by mixture D at 20 and 40% amendment rate. The results of this study suggest that though SLASH amendment for growing Palak improved the physico chemical properties of soil amended and also the yield of the plants in some treatments, it may not be a good option due to risk of contamination of heavy metals such as Cr, Cd and Zn showing higher accumulation. PMID- 29468395 TI - Differences in fluorescence characteristics and bioavailability of water-soluble organic matter (WSOM) in sediments and suspended solids in Lihu Lake, China. AB - The spectral characteristics, spatial distribution, and bioavailability of water soluble organic matter (WSOM) in suspended solids and surface sediments of Lihu Lake, China, were investigated through excitation-emission matrix spectra and parallel factor analysis. The average content of dissolved organic carbon (DOC) in the sediments reached 643.28 +/- 58.34 mg C/kg and that in suspended solids was 714.87 +/- 69.24 mg C/kg. The fluorescence intensity of WSOM totaled 90.87 +/ 5.65 and 115.42 +/- 8.02 RU/g for the sediments and suspended solids, respectively. The DOC and fluorescence intensity of the WSOM showed an increasing trend moving from the west to the east of the lake. The WSOM in sediments and suspended solids contained two humic-like (C1 and C2) and one tryptophan-like (C3) components. These components had different fluorescent peaks and relative proportions. In the sediments, the relative proportions of C1, C2, and C3 were 33.71% +/- 0.71, 26.83% +/- 0.68, and 39.50% +/- 0.71%, respectively. Meanwhile, C1 (35.77 +/- 0.84%), C2 (34.07 +/- 0.61%), and C3 (30.16 +/- 0.75%) had similar relative percentages in suspended solids. The sediments had a lower humification index (3.02 +/- 0.08) than the suspended solids (4.04 +/- 0.15). Exchangeable nitrogen for the sediments and suspended solids was dominated by exchangeable ammonium nitrogen and soluble organic nitrogen, respectively. WSOM plays an important role in migration and transformation of nitrogen in sediments and suspended solids. The sediment-derived WSOM exhibited higher lability and biological activity than did the suspended solid-derived WSOM. The relative ratio of the intensity of protein-like fluorescent component to that of the humic-like one can be used as a reference index to evaluate the lability and biological activity of WSOM in sediments and suspended solids.

AB - The phytoremediation of copper (Cu)-contaminated sandy soils can be influenced by the addition of vermicompost to the soil and the mycorrhization of plants. The objective of this study was to evaluate the effects of inoculation with the mycorrhizal fungus Rhizophagus clarus and the addition of different doses of bovine manure vermicompost on the phytoremediation of a sandy soil with a high Cu content using Canavalia ensiformis. Soil contaminated with 100 mg kg-1 Cu received five doses of vermicompost and was cultivated with C. ensiformis, with and without inoculation with mycorrhizal fungus, and the Cu and nutrients in the soil and soil solution were evaluated. The concentrations of Cu and other nutrients and the biomass and Cu phytotoxicity in the plants were quantified by gauging the photochemical efficiency, concentration of photosynthetic pigments and activity of oxidative stress enzymes. The vermicompost increased the soil pH and nutrient concentrations and reduced the Cu content of the solution. When the vermicompost was applied at a dose equivalent to 80 mg phosphorus (P) kg-1, the phytoextraction efficiency was higher, but the phytostabilization efficiency was higher for vermicompost doses of 10 and 20 mg P kg-1. The presence of mycorrhizal fungi increased Cu phytostabilization, especially at vermicompost doses of 10 and 20 mg P kg-1. The use of vermicompost at low doses and inoculation with mycorrhizal fungi increase the phytostabilization potential of C. ensiformis in sandy soil contaminated by Cu. PMID- 29468397 TI - Indoor radon concentration in Korea residential environments. AB - The purpose of this study is to provide basic data for the evaluation and management of health effects with respect to exposure to radon within residential environments in South Korea. It is part of a case-control study to develop a management plan based on indoor radon exposure levels and assess their impact on health. To investigate the long-term cumulative concentration levels of radon, 599 patients who have respiratory diseases were recruited in South Korea, and alpha track detectors were installed in their residences for a period of 3 months from mid-2015 to late 2016. A survey was then conducted to determine the factors affecting the radon concentration. The radon concentration levels were analyzed in conjunction with the survey results. The results show that the arithmetic mean of the radon concentrations in domestic residences was in the range of 70.8 +/- 65.2 Bq/m3. An analysis of covariance (ANCOVA) was performed to identify the environmental factors affecting the radon concentration and contributing to variations in the residential radon concentration based on the height of the residence. The results show that the contribution of the local environmental factor to the variation in radon concentration (p < 0.05) was greater than that of other environmental factors. Although no statistically significant difference was found with regard to the construction year of the building before the control (p > 0.05), the same was found with regard to the construction year after the control (p < 0.05). PMID- 29468398 TI - Characterization, evaluation, and mechanistic insights on the adsorption of antimonite using functionalized carbon nanotubes. AB - Floating catalytic chemical vapor deposition technique was used for synthesizing carbon nanotubes (CNTs) using ferrocene in benzene as the hydrocarbon source. The functionalization of CNTs was carried out by oxidation followed by grafting of potassium iodide (KI) and mercaptoethanol (HS(CH2)2OH) ligands to produce iodide grafted CNTs (CNT-I) and thiol-functionalized CNTs (CNT-SH), respectively. The resulting adsorbents have been thoroughly characterized by various techniques. Fourier transform infrared (FTIR) spectroscopy and X-ray photoelectron spectroscopy (XPS) studies revealed the efficient grafting of the ligands. Further, their adsorption capacities towards antimonite have been assessed. The adsorption kinetics fitted the pseudo-second-order model for both the adsorbents. Moreover, the adsorption of Sb(III) followed Langmuir and Freundlich's model. The maximum adsorption capacity of CNT-I and CNT-SH for Sb(III) at pH 7 was found to be 200 and 140.85 mg/g, respectively. The interference effect of various ions on the adsorption of antimonite was studied. A suitable mechanism for Sb(III) adsorption has been postulated using TEM, XRD, XPS, and FTIR. The adaptability of the adsorbents was demonstrated by the removal capacity of Sb(III) at parts per billion levels from nuclear decontamination formulation (NAC) and tap water matrix as well. PMID- 29468399 TI - Pedotransfer functions of potentially toxic elements in tropical soils cultivated with vegetable crops. AB - The anthropogenic input of potentially toxic elements (PTEs) from industry, agrochemicals, etc., into the environment are of great concern. Models derived from pedotransfer functions can provide estimates of the levels of PTEs based on soil attributes. Based on the importance of these models in studies in contaminated areas, we assessed the concentrations of the reactive contents of Ba, Cu, Cr, Ni, Pb, and Zn in soils cultivated with vegetable crops in the state of Sao Paulo, Brazil. We also evaluated the influence of chemical and physical soil attributes on their reactivity and availability. The reactive contents of PTEs represent the fraction of PTEs easily sorbed at the adsorptions sites of organic matter, iron hydroxides, or clay. This fraction can supply information about the PTE content that is more or less readily released into the soil solution. The reactive and available fraction was extracted with 0.43 M HNO3 and 0.01 M CaCl2, respectively. The proportion of reactivity of metal pools decreased in the order of Ba>Zn > Cu > Pb > Ni > Cr. The empirical models were able to predict the relationship between the reactive fractions, the pseudototal content, and the soil attributes. The available concentrations of Cr, Cu, Ni, and Pb in the soils were lower than the limit of quantification, while 3% of the Ba content and 1% of the Zn content were available in the soil solution in relation to their pseudototal content, suggesting low mobility of these elements in the soil. PMID- 29468400 TI - Assessment of groundwater vulnerability by applying the modified DRASTIC model in Beihai City, China. AB - This study assesses vulnerability of groundwater to pollution in Beihai City, China, as a support of groundwater resource protection. The assessment result not only objectively reflects potential possibility of groundwater to contamination but also provides scientific basis for the planning and utilization of groundwater resources. This study optimizes the parameters consisting of natural factors and human factors upon the DRASTIC model and modifies the ratings of these parameters, based on the local environmental conditions for the study area. And a weight of each parameter is assigned by the analytic hierarchy process (AHP) to reduce the subjectivity of humans to vulnerability assessment. The resulting scientific ratings and weights of modified DRASTIC model (AHP-DRASTLE model) contribute to obtain the more realistic assessment of vulnerability of groundwater to contaminant. The comparison analysis validates the accuracy and rationality of the AHP-DRASTLE model and shows it suits the particularity of the study area. The new assessment method (AHP-DRASTLE model) can provide a guide for other scholars to assess the vulnerability of groundwater to contamination. The final vulnerability map for the AHP-DRASTLE model shows four classes: highest (2%), high (29%), low (55%), and lowest (14%). The vulnerability map serves as a guide for decision makers on groundwater resource protection and land use planning at the regional scale and that it is adapted to a specific area.

AB - BACKGROUND: The nationwide prevention program "Parent Guide - Growing up Healthy" aims to improve parental health knowledge in Germany. At the birth of their first child, parents of any socioeconomic status (SES) are provided with written educational material that includes relevant health knowledge as well as basic information about routine health checkups for children. OBJECTIVES: This study aimed at evaluating the program regarding 1) the effects on parental health knowledge and parental satisfaction with routine child health checkups, 2) the sensitivity of the effects on SES, and 3) parental acceptance of the written educational material. MATERIALS AND METHODS: A longitudinal randomized controlled trial (RCT) was carried out with 1318 young parents recruited from 14 hospitals with maternity clinics in Germany. Parents of the intervention group received educational material whereas controls didn't receive material. Respondents completed interviews at the child's birth (T0) and first birthday (T1). RESULTS: Parental health knowledge at T1 was significantly higher (p = 0.005; partial eta2 = 0.006) in the intervention group but with a small effect size. The influence of the educational material was not moderated by SES (p = 0.456). Satisfaction with routine child health checkups did not differ significantly between the groups (p = 0.606). Parents showed high acceptance of the parent guide regardless of SES. CONCLUSIONS: Written educational material is an effective approach in increasing parental health knowledge and has the potential to reach all parents regardless of SES. A higher satisfaction with routine child health checkups could not be achieved by educational material. PMID- 29468401 TI - The Role of the Genitourinary Microbiome in Pediatric Urology: a Review. AB - PURPOSE OF REVIEW: In this review, we highlight the effects of the microbiome on urologic diseases that affect the pediatric patient. RECENT FINDINGS: Perturbations in the urinary microbiome have been shown to be associated with a number of urologic diseases affecting children, namely urinary tract infection, overactive bladder/urge urinary incontinence, and urolithiasis. Recently, improved cultivation and sequencing technologies have allowed for the discovery of a significant and diverse microbiome in the bladder, previously assumed to be sterile. Early studies aimed to identify the resident bacterial species and demonstrate the efficacy of sequencing and enhanced quantitative urine culture. More recently, research has sought to elucidate the association between the microbiome and urologic disease, as well as to demonstrate effects of manipulation of the microbiome on various urologic pathologies. With an improved appreciation for the impact of the urinary microbiome on urologic disease, researchers have begun to explore the impact of these resident bacteria in pediatric urology.

PMID- 29468405 TI - Efficacy and safety of ripasudil, a Rho-associated kinase inhibitor, in eyes with uveitic glaucoma. AB - PURPOSE: The purpose of this study was to describe the initial experience, efficacy, and safety of ripasudil hydrochloride hydrate (ripasudil), a Rho associated kinase inhibitor eye drop, for uveitic glaucoma. METHODS: In this retrospective case series, we retrieved the clinical data of 21 eyes from 19 patients with open-angle uveitic glaucoma who were treated with ripasudil at Kobe University Hospital. We analyzed the median intraocular pressure (IOP) reductions after ripasudil treatment and collected the information on the adverse events that were encountered during the course of this treatment period. RESULTS: The causes of uveitis were sarcoidosis (29%), Behcet's disease (14%), Vogt-Koyanagi Harada disease (10%), others (15%), and unclassified (33%). Of total, 19 (90%) eyes were treated with topical, periocular, and/or systemic steroid therapies. The median number of glaucoma medications used before ripasudil treatment was 2, and the median follow-up time was 13 months. The median IOPs were 23 mmHg at baseline, 16 mmHg at 1 month, and 18 mmHg at 12 months with significant IOP reductions of - 3 mmHg at 1 month and - 2 mmHg at 12 months (P = 0.0050). Of total, 11 (52%) eyes with an IOP reduction >= 3 mmHg at 1 month (responders) showed a significant median IOP decrease at 12 months compared with non responders (- 5 versus 0 mmHg, P = 0.0242). Two adverse events were observed: rashes on the back and transient conjunctival hyperemia. CONCLUSIONS: Ripasudil appears to be safe and substantially reduce IOP in eyes with uveitic glaucoma if the eye is a responder. Ripasudil could be an option for the treatment of uveitic glaucoma. PMID- 29468404 TI - Evaluation of Pancreatic VMAT2 Binding with Active and Inactive Enantiomers of [18F]FP-DTBZ in Healthy Subjects and Patients with Type 1 Diabetes. AB - PURPOSE: Previous studies demonstrated the utility of [18F]fluoropropyl-(+) dihydrotetrabenazine ([18F]FP-(+)-DTBZ) as a positron emission tomography (PET) radiotracer for the vesicular monoamine transporter type 2 (VMAT2) to quantify beta cell mass in healthy control (HC) and type 1 diabetes mellitus (T1DM) groups. Quantification of specific binding requires measurement of non displaceable uptake. Our goal was to identify a reference tissue (renal cortex or spleen) to quantify pancreatic non-specific binding of [18F]FP-(+)-DTBZ with the inactive enantiomer, [18F]FP-(-)-DTBZ. This was the first human study of [18F]FP (-)-DTBZ. PROCEDURES: Six HCs and four T1DM patients were scanned on separate days after injection of [18F]FP-(+)-DTBZ or [18F]FP-(-)-DTBZ. Distribution volumes (VT) and standardized uptake values (SUVs) were compared between groups. Three methods for calculation of non-displaceable uptake (VND) or reference SUV were applied: (1) use of [18F]FP-(+)-DTBZ reference VT as VND, assuming VND is uniform across organs; (2) use of [18F]FP-(-)-DTBZ pancreatic VT as VND, assuming that VND is uniform between enantiomers in the pancreas; and (3) use of a scaled [18F]FP-(+)-DTBZ reference VT as VND, assuming that a ratio of non-displaceable uptake between organs is uniform between enantiomers. Group differences in VT (or SUV), binding potential (BPND), or SUV ratio (SUVR) were estimated using these three methods. RESULTS: [18F]FP-(-)-DTBZ VT values were different among organs, and VT(+) and VT(-) were also different in the renal cortex and spleen. Method 3 with the spleen to estimate VND (or reference SUV) gave the highest non displaceable uptake and the largest HC vs. T1DM group differences. Significant group differences were also observed in VT (or SUV) with method 1 using spleen. SUV was affected by differences in the input function between groups and between enantiomers. CONCLUSIONS: Non-displaceable uptake was different among organs and between enantiomers. Use of scaled spleen VT values for VND is a suitable method for quantification of VMAT2 in the pancreas. PMID- 29468406 TI - Comparison of anterior segment optical coherence tomography angiography and fluorescein angiography for iris vasculature analysis. AB - PURPOSE: The aim of this study is to perform imaging of irises of different colors using spectral domain anterior segment optical coherence tomography angiography (AS-OCTA) and iris fluorescein angiography (IFA) and compare their effectiveness in examining iris vasculature. METHODS: This is a cross-sectional observational clinical study. Patients with no vascular iris alterations and different pigmentation levels were recruited. Participants were imaged using OCTA adapted with an anterior segment lens and IFA with a confocal scanning laser ophthalmoscope (cSLO) adapted with an anterior segment lens. AS-OCTA and IFA images were then compared. Two blinded readers classified iris pigmentation and compared the percentage of visible vessels between OCTA and IFA images. RESULTS: Twenty eyes of 10 patients with different degrees of iris pigmentation were imaged using AS-OCTA and IFA. Significantly more visible iris vessels were observed using OCTA than using FA (W = 5.22; p < 0.001). Iris pigmentation was negatively correlated to the percentage of visible vessels in both imaging methods (OCTA, rho = - 0.73, p < 0.001; IFA, rho = - 0.77, p < 0.001). Unlike FA, AS-OCTA could not detect leakage of dye, delay, or impregnation. Nystagmus and inadequate fixation along with motion artifacts resulted in lower quality images in AS-OCTA than in IFA. CONCLUSIONS: AS-OCTA is a new imaging modality which allows analysis of iris vasculature. In both AS-OCTA and IFA, iris pigmentation caused vasculature imaging blockage, but AS-OCTA provided more detailed iris vasculature images than IFA. Additional studies including different iris pathologies are needed to determine the most optimal scanning parameters in OCTA of the anterior segment. PMID- 29468408 TI - Is ICER NICEr? PMID- 29468407 TI - Intravenous immunoglobulin for the treatment of intractable cholangitis after Kasai portoenterostomy in biliary atresia patients. AB - OBJECTIVE: To assess the efficacy of intravenous immunoglobulin (IVIG) as add-on treatment for intractable cholangitis (IC) after Kasai portoenterostomy (KPE) in biliary atresia (BA) patients. METHODS: 113 BA patients who had one or more episodes of cholangitis after KPE were recruited in this study. According to whether response to routine conservative treatment, all patients were divided into IC group and simple cholangitis (SC) group. Meanwhile, patients with IC subdivided into IVIG group and control group according to whether application of IVIG. RESULTS: The IC group had higher serum procalcitonin (PCT) (P = 0.014), C reactive protein (CRP) (P = 0.023), and gamma-Gltamyltranspeptidase (gamma-GGT) (P = 0.031) level than the SC group. The IVIG group had shorter duration of fever after treatment (P = 0.011) and length of hospital stay (P = 0.018) than the control group. The time until recurrent episode of cholangitis was significant longer in IVIG group than in control group (P = 0.019). CONCLUSIONS: IVIG as add on treatment may be an effective treatment for the cholangitis acute episode, and we conclude by calling for more prospective studies to attest to the role of IVIG in the treatment of cholangitis. PMID- 29468409 TI - Performance of Arsi-Bale sheep fed urea treated maize cob as basal diet and supplemented with graded levels of concentrate mixture. AB - The experiment was conducted using 20 yearling intact male Arsi-Bale sheep with a mean body weight of 20.56 +/- 0.45 (mean +/- SD) to investigate the performance and economic benefit of graded levels of concentrate supplementation to urea treated maize cob (UTMC)-based diet. The experiment consisted of 7 days of digestibility trial and subsequent 90 days of feeding trial. Before the commencement of the experiment, sheep were vaccinated against common infectious diseases, dewormed, and disinfected against internal and external parasites, respectively. The experimental design was randomized complete block design. The sheep were grouped into five blocks of four animals based on their initial body weight, and one animal from each block was randomly assigned to one of the four treatments. The treatments included ad libitum feeding of UTMC (T1) and supplementation with a concentrate mixture composed of wheat bran (WB) and noug seed cake (NSC) in 2:1 ratio, which were offered at 150 g (T2), 250 g (T3), and 350 g (T4) DM/head/day. The CP content of the UTMC was 9.3% on DM basis. The daily DM intake of UTMC was higher (P < 0.001) for T4 (614.6 g) compared to T1 (505.1 g), T2 (538.9 g), and T3 (590.3 g). Total DM intake was higher (P < 0.001) for supplemented treatments T2 (688.4 g), T3 (844.1 g), and T4 (966.9 g). Supplementation did not improve (P > 0.05) digestibility of DM, OM, NDF, and ADF, except CP digestibility which was significant (P < 0.001) across treatments. Supplementation increased (P < 0.001) final body weight (FBWT), feed conversion efficiency (FCE), and average daily weight gain (ADG). The average daily gain (ADG) was highest (P < 0.001) in T4 (80.8 +/- 7.74 g/day) followed by T3 (33.3 +/ 7.74 g/day) and T2 (23.1 +/- 0.95 kg) whereas the un-supplemented animals lost about 9.2 g/day. The highest total return, net income, and marginal rate of return were observed in higher level supplemented sheep than the control. Therefore, T4 improved biological performance and marginal rate of return than the other treatments and can be considered as better alternative feed supplement in UTMC-based feeding of Arsi-Bale sheep in Ethiopia.

AB - In the growing scenario, microarray data is extensively used since it provides a more comprehensive understanding of genetic variants among diseases. As the gene expression samples have high dimensionality it becomes tedious to analyze the samples manually. Hence an automated system is needed to analyze these samples. The fuzzy expert system offers a clear classification when compared to the machine learning and statistical methodologies. In fuzzy classification, knowledge acquisition would be a major concern. Despite several existing approaches for knowledge acquisition much effort is necessary to enhance the learning process. This paper proposes an innovative Hybrid Stem Cell (HSC) algorithm that utilizes Ant Colony optimization and Stem Cell algorithm for designing fuzzy classification system to extract the informative rules to form the membership functions from the microarray dataset. The HSC algorithm uses a novel Adaptive Stem Cell Optimization (ASCO) to improve the points of membership function and Ant Colony Optimization to produce the near optimum rule set. In order to extract the most informative genes from the large microarray dataset a method called Mutual Information is used. The performance results of the proposed technique evaluated using the five microarray datasets are simulated. These results prove that the proposed Hybrid Stem Cell (HSC) algorithm produces a precise fuzzy system than the existing methodologies.

AB - Comparative studies of the level of DNA damage induced in vitro by X-rays (0-8 Gy) or hydrogen peroxide (0-300 uM) in cells of blood, spleen, and bone marrow of mice and in blood cells of frogs and humans were performed using the alkaline comet assay. For both agents, the levels of induced DNA damage in leucocytes/splenocytes of mice were higher than those in blood cells of frogs and humans, while in human leucocytes, they were comparable with those in frog blood cells. The rate of DNA repair in frog blood cells was very slow. The results suggest that the levels of radiation-induced DNA damage are not in accordance with species radiosensitivity (according to LD50/30) but rather with the intrinsic peculiarities of cells.

He was found comatose. The initial diagnosis was difficult. In hospital he suffered from rhabdomyolysis with renal failure and sepsis rapidly developed. After renal replacement treatment with hemodialysis, long-term artificial ventilation with tracheotomy and a 3-week stay in the intensive care unit, the patient could be discharged to a rehabilitation center. PMID- 29468415 TI - The ileal FGF15/19 to hepatic FGFR4 axis regulates liver regeneration after partial hepatectomy in mice. AB - Fibroblast growth factor (FGF) has been considered to modulate liver regeneration (LR) after partial hepatectomy (PH) at the tissue level. Previous studies have demonstrated that FGF15 and FGF19 induce the activation of its receptor, FGF receptor 4 (FGFR4), which can promote hepatocellular carcinoma progression and regulate liver lipid metabolism. In this study, we aimed to explore the role of the ileal FGF15/19- hepatic FGFR4 axis in the LR after PH. Male C57BL/6 mice aged 8-12 weeks were partially hepatectomized and assessed for expression of ileal FGF15/19 to hepatic FGFR4 signaling. We used recombinant human FGF19 protein and a small interfering RNA (siRNA) of FGFR4 to regulate expression of the FGF15/19 FGFR4 axis in vitro and in vivo. The proliferation and cell cycle of hepatocytes, the expression levels of FGF15/19-FGFR4 downstream molecules, liver recovery, and lipid metabolism were assessed. We found that both ileal and serum FGF15 expression were upregulated and hepatic FGFR4 was activated after PH in mice. FGF15/19 promoted cell cycle progression, enhanced proliferation, and reduced hepatic lipid accumulation of hepatocytes both in vitro and in vivo. Furthermore, the proliferative effect and lipid regulatory properties of FGF15/19 were dependent on FGFR4 in hepatocytes. In addition, ileal FGF15/19-hepatic FGFR4 transduction during hepatocyte proliferation was regulated by extracellular regulated protein kinase (ERK) 1/2. In conclusion, the ileal FGF15/19 to hepatic FGFR4 axis is activated and promotes LR after PH in mice, supporting the potential of ileal FGF15/19 to hepatic FGFR4 axis-targeted therapy to enhance LR after PH. PMID- 29468416 TI - Motivational sensitivity of outcome-response priming: Experimental research and theoretical models. AB - Outcome-response (O-R) priming is at the core of various associative theories of human intentional action. This is a simple and parsimonious mechanism by which activation of outcome representations (e.g. thinking about the light coming on) leads to activation of the associated motor patterns required to achieve it (e.g. pushing the light switch). In the current manuscript, we review the evidence for such O-R associative links demonstrated by converging (yet until now, separate) strands of research. While there is a wealth of evidence that both the perceptual and motivational properties of an outcome can be encoded in the O-R association and mediate O-R priming, we critically examine the integration of these mechanisms and the conditions under which motivational factors constrain the sensory O-R priming effect. We discuss the clinical relevance of this O-R priming mechanism, whether it can satisfactorily account for human goal-directed behaviour, and the implications for theories of human action control. PMID- 29468417 TI - Eliciting the experiences of the adolescent-parent dyad following critical care admission: a pilot study. AB - : Critically ill adolescents are usually treated on intensive care units optimised for much older adults or younger children. The way they access and experience health services may be very different to most adolescent service users, and existing quality criteria may not apply to them. The objectives of this pilot study were, firstly, to determine whether adolescents and their families were able to articulate their experiences of their critical care admission and secondly, to identify the factors that are important to them during their intensive care unit (ICU) or high dependency unit (HDU) stay. Participants were 14-17 year olds who had previously had an emergency admission to an adult or paediatric ICU/HDU in one of four UK hospitals (two adult, two paediatric) and their parents. Semi-structured interviews were conducted with eight mother adolescent dyads and one mother. Interviews were transcribed and analysed using framework analysis. CONCLUSION: The main reported determinant of high-quality care was the quality of interaction with staff. The significance of these interactions and their environment depended on adolescents' awareness of their surroundings, which was often limited in ICU and changed significantly over the course of their illness. Qualitative interview methodology would be difficult to scale up for this group. What is known * Critically ill adolescents are usually treated on intensive care units optimised for older adults or younger children. * The way they access and experience health services may be different to most adolescent patients; existing quality criteria may not apply. What is new * Reported determinants of high-quality care were age-appropriateness of the environment, respectfulness and friendliness of staff, communication and inclusion in healthcare decisions. * The significance of these depended on adolescents' awareness of their surroundings, which was often limited and changed over the course of their illness. PMID- 29468418 TI - Matrix Optical Absorption in UV-MALDI MS. AB - In ultraviolet matrix-assisted laser desorption/ionization mass spectrometry (UV MALDI MS) matrix compound optical absorption governs the uptake of laser energy, which in turn has a strong influence on experimental results. Despite this, quantitative absorption measurements are lacking for most matrix compounds. Furthermore, despite the use of UV-MALDI MS to detect a vast range of compounds, investigations into the effects of laser energy have been primarily restricted to single classes of analytes. We report the absolute solid state absorption spectra of the matrix compounds alpha-cyano-4-hydroxycinnamic acid (CHCA), para nitroaniline (PNA), 2-mercaptobenzothiazole (MBT), 2,5-dihydroxybenzoic acid (2,5 DHB), and 2,4,6-trihydroxyacetophenone (THAP). The desorption/ionization characteristics of these matrix compounds with respect to laser fluence was investigated using mixed systems of matrix with either angiotensin II, PC(34:1) lipid standard, or haloperidol, acting as representatives for typical classes of analyte encountered in UV-MALDI MS. The first absolute solid phase spectra for PNA, MBT, and THAP are reported; additionally, inconsistencies between previously published spectra for CHCA are resolved. In light of these findings, suggestions are made for experimental optimization with regards to matrix and laser wavelength selection. The relationship between matrix optical cross-section and wavelength-dependant threshold fluence, fluence of maximum ion yield, and R, a new descriptor for the change in ion intensity with fluence, are described. A matrix cross-section of 1.3 * 10-17 cm-2 was identified as a potential minimum for desorption/ionization of analytes. Graphical Abstract ?. PMID- 29468419 TI - Establishment of an Italian chronic migraine database: a multicenter pilot study. AB - To optimize chronic migraine (CM) ascertainment and phenotype definition, provide adequate clinical management and health care procedures, and rationalize economic resources allocation, we performed an exploratory multicenter pilot study aimed at establishing a CM database, the first step for developing a future Italian CM registry. We enrolled 63 consecutive CM patients in four tertiary headache centers screened with face-to-face interviews using an ad hoc dedicated semi structured questionnaire gathering detailed information on life-style, behavioral and socio-demographic factors, comorbidities, and migraine features before and after chronicization and healthcare resource use. Our pilot study provided useful insights revealing that CM patients (1) presented in most cases symptoms of peripheral trigeminal sensitization, a relatively unexpected feature which could be useful to unravel different CM endophenotypes and to predict trigeminal targeted treatments' responsiveness; (2) had been frequently admitted to emergency departments; (3) had undergone, sometime repeatedly, unnecessary or inappropriate investigations; (4) got rarely illness benefit exemption or disability allowance only. We deem that the expansion of the database-shortly including many other Italian headache centers-will contribute to more precisely outline CM endophenotypes, hence improving management, treatment, and economic resource allocation, ultimately reducing CM burden on both patients and health system. PMID- 29468420 TI - Temperature-Induced Surface Effects on Drug Nanosuspensions. AB - PURPOSE: The trial-and-error approach is still predominantly used in pharmaceutical development of nanosuspensions. Physicochemical dispersion stability is a primary focus and therefore, various analytical bulk methods are commonly employed. Clearly less attention is directed to surface changes of nanoparticles even though such interface effects can be of pharmaceutical relevance. Such potential effects in drug nanosuspensions were to be studied for temperatures of 25 and 37 degrees C by using complementary surface analytical methods. METHODS: Atomic force microscopy, inverse gas chromatography and UV surface dissolution imaging were used together for the first time to assess pharmaceutical nanosuspensions that were obtained by wet milling. Fenofibrate and bezafibrate were selected as model drugs in presence of sodium dodecyl sulfate and hydroxypropyl cellulose as anionic and steric stabilizer, respectively. RESULTS: It was demonstrated that in case of bezafibrate nanosuspension, a surface modification occurred at 37 degrees C compared to 25 degrees C, which notably affected dissolution rate. By contrast, no similar effect was observed in case of fenofibrate nanoparticles. CONCLUSIONS: The combined usage of analytical surface methods provides the basis for a better understanding of phenomena that take place on drug surfaces. Such understanding is of importance for pharmaceutical development to achieve desirable quality attributes of nanosuspensions. PMID- 29468422 TI - Molecular profiling and comprehensive genome-wide analysis of somatic copy number alterations in gastric intramucosal neoplasias based on microsatellite status. AB - BACKGROUND: We attempted to identify the molecular profiles of gastric intramucosal neoplasia (IMN; low-grade dysplasia, LGD; high-grade dysplasia, HGD; intramucosal cancer, IMC) by assessing somatic copy number alterations (SCNAs) stratified by microsatellite status (microsatellite stable, MSS; microsatellite instable, MSI). Thus, microsatellite status was determined in 84 tumors with MSS status and 16 tumors with MSI status. METHODS: One hundred differentiated type IMNs were examined using SCNAs. In addition, genetic mutations (KRAS, BRAF, PIK3CA, and TP53) and DNA methylation status (low, intermediate and high) were also analyzed. Finally, we attempted to identify molecular profiles using a hierarchical clustering analysis. RESULTS: Three patterns could be categorized according to SCNAs in IMNs with the MSS phenotype: subgroups 1 and 2 showing a high frequency of SCNAs, and subgroup 3 displaying a low frequency of SCNAs (subgroup 1 > 2 > 3 for SCNA). Subgroup 1 could be distinguished from subgroup 2 by the numbers of total SCNAs (gains and losses) and SCN gains (subgroup 1 > 2). The SCNA pattern of LGD was different from that of HGD and IMC. Moreover, IMNs with the MSI phenotype could be categorized into two subtypes: high frequency of SCNAs and low frequency of SCNAs. Genetic mutations and DNA methylation status did not differ among subgroups in IMNs. CONCLUSION: Molecular profiles stratified by SCNAs based on microsatellite status may be useful for elucidation of the mechanisms of early gastric carcinogenesis. PMID- 29468423 TI - A novel method for studying airway hyperresponsiveness in allergic guinea pigs in vivo using the PreciseInhale system for delivery of dry powder aerosols. AB - Inhaled adenosine receptor agonists induce bronchoconstriction and inflammation in asthma and are used as bronchial challenge agents for the diagnosis of asthma and in respiratory drug development. Recently developed dry powder aerosols of adenosine have several advantages over nebulised adenosine 5'-monophosphate (AMP) as bronchial challenge agents. However, reverse translation of this bronchial challenge technique to pre-clinical drug development is limited by the difficulty of administering powder aerosols to animals. The aim of the current study was to develop methods for delivering powder aerosols of adenosine receptor agonists to sensitised guinea pigs (as a model of allergic asthma) and evaluate their effect as challenge agents for the measurement of airway responsiveness. The PreciseInhale system delivered micronised AMP and adenosine powders, with mass median aerodynamic diameters of 1.81 and 3.21 MUm and deposition fractions of 31 and 48% in the lungs, respectively. Bronchoconstrictor responses in passively sensitised, anaesthetised, spontaneously breathing guinea pigs were compared to responses to nebulised and intravenously administered AMP and adenosine. AMP- and adenosine-induced bronchoconstriction following all routes of administration with the magnitude of response ranking intravenous > dry powder > nebulisation, probably reflecting differences in exposure to the adenosine agonists delivered by the different routes. In conclusion, the PreciseInhale system delivered AMP and adenosine dry powder aerosols accurately into the lungs, suggesting this method can be used to investigate drug effects on airway responsiveness. PMID- 29468424 TI - Full depth measurement of tenofovir transport in rectal mucosa using confocal Raman spectroscopy and optical coherence tomography. AB - The prophylactic activity of antiretroviral drugs applied as microbicides against sexually transmitted HIV is dependent upon their concentrations in infectable host cells. Within mucosal sites of infection (e.g., vaginal and rectal mucosa), those cells exist primarily in the stromal layer of the tissue. Traditional pharmacokinetic studies of these drugs have been challenged by poor temporal and spatial specificity. Newer techniques to measure drug concentrations, involving Raman spectroscopy, have been limited by laser penetration depth into tissue. Utilizing confocal Raman spectroscopy (RS) in conjunction with optical coherence tomography (OCT), a new lateral imaging assay enabled concentration distributions to be imaged with spatial and temporal specificity throughout the full depth of a tissue specimen. The new methodology was applied in rectal tissue using a clinical rectal gel formulation of 1% tenofovir (TFV). Confocal RS revealed diffusion-like behavior of TFV through the tissue specimen, with significant partitioning of the drug at the interface between the stromal and adipose tissue layers. This has implications for drug delivery to infectable tissue sites. The new assay can be applied to rigorously analyze microbicide transport and delineate fundamental transport parameters of the drugs (released from a variety of delivery vehicles) throughout the mucosa, thus informing microbicide product design. PMID- 29468425 TI - Sediment matrix characterization as a tool for evaluating the environmental impact of heavy metals in metal mining, smelting, and ore processing areas. AB - In this work, the matrix characterization (mineralogy, total and local chemical composition, and total organic (TOC) and inorganic carbon (TIC) contents) of different types of sediments from mining- and metallurgy-influenced areas and the assessment of the impact of the matrix on the association of potentially hazardous metals with the mineral phases of these samples, which affect their mobility in the environment, are presented. For these purposes, sediment samples with different origins and from different locations in the environment were analyzed. Anthropogenic sediments from metal-rich post-flotation tailings (Lintich, Slovakia) represent waste from ore processing, natural river sediments from the Hornad River (Kosice, Slovakia) represent areas influenced predominantly by the metallurgical industry, and lake sediments from a water reservoir Ruzin (inflow from the Hornad and Hnilec Rivers, Slovakia) represent the impact of the metallurgical and/or mining industries. The total metal contents were determined by X-ray fluorescence (XRF) analysis, the local chemical and morphological microanalysis by scanning electron microscopy with energy-dispersive spectroscopy (SEM-EDS), and the TOC and TIC contents by infrared (IR) spectrometry. The mobility/bioavailability of Cu, Pb, and Zn in/from sediments at the studied areas was assessed by ethylenediaminetetraacetic acid (EDTA) and acetic acid (AA) extraction and is discussed in the context of the matrix composition. The contents of selected potentially hazardous elements in the extracts were determined by the high-resolution continuum source flame atomic absorption spectrometry (HR-CS FAAS). PMID- 29468426 TI - EPR spectroscopy of complex biological iron-sulfur systems. AB - From the very first discovery of biological iron-sulfur clusters with EPR, the spectroscopy has been used to study not only purified proteins but also complex systems such as respiratory complexes, membrane particles and, later, whole cells. In recent times, the emphasis of iron-sulfur biochemistry has moved from characterization of individual proteins to the systems biology of iron-sulfur biosynthesis, regulation, degradation, and implications for human health. Although this move would suggest a blossoming of System-EPR as a specific, non invasive monitor of Fe/S (dys)homeostasis in whole cells, a review of the literature reveals limited success possibly due to technical difficulties in adherence to EPR spectroscopic and biochemical standards. In an attempt to boost application of System-EPR the required boundary conditions and their practical applications are explicitly and comprehensively formulated.

AB - Iterative screening has emerged as a promising approach to increase the efficiency of screening campaigns compared to traditional high throughput approaches. By learning from a subset of the compound library, inferences on what compounds to screen next can be made by predictive models, resulting in more efficient screening. One way to evaluate screening is to consider the cost of screening compared to the gain associated with finding an active compound. In this work, we introduce a conformal predictor coupled with a gain-cost function with the aim to maximise gain in iterative screening. Using this setup we were able to show that by evaluating the predictions on the training data, very accurate predictions on what settings will produce the highest gain on the test data can be made. We evaluate the approach on 12 bioactivity datasets from PubChem training the models using 20% of the data. Depending on the settings of the gain-cost function, the settings generating the maximum gain were accurately identified in 8-10 out of the 12 datasets. Broadly, our approach can predict what strategy generates the highest gain based on the results of the cost-gain evaluation: to screen the compounds predicted to be active, to screen all the remaining data, or not to screen any additional compounds. When the algorithm indicates that the predicted active compounds should be screened, our approach also indicates what confidence level to apply in order to maximize gain. Hence, our approach facilitates decision-making and allocation of the resources where they deliver the most value by indicating in advance the likely outcome of a screening campaign.

AB - Extremophilic microorganisms are a rich source of enzymes, the enzymes which can serve as industrial catalysts that can withstand harsh processing conditions. An example is thermostable beta-glucosidases that are addressing a challenging problem in the biodiesel industry: removing steryl glucosides (SGs) from biodiesel. Steryl glucosidases (SGases) must be tolerant to heat and solvents in order to function efficiently in biodiesel. The amphipathic nature of SGs also requires enzymes with an affinity for water/solvent interfaces in order to achieve efficient hydrolysis. Additionally, the development of an enzymatic process involving a commodity such as soybean biodiesel must be cost-effective, necessitating an efficient manufacturing process for SGases. This review summarizes the identification of microbial SGases and their applications, discusses biodiesel refining processes and the development of analytical methods for identifying and quantifying SGs in foods and biodiesel, and considers technologies for strain engineering and process optimization for the heterologous production of a SGase from Thermococcus litoralis. All of these technologies might be used for the production of other thermostable enzymes. Structural features of SGases and the feasibility of protein engineering for novel applications are explored.

AB - Lipases are physiologically important and ubiquitous enzymes that share a conserved domain and are classified into eight different families based on their amino acid sequences and fundamental biological properties. The Lipase3 family of lipases was reported to possess a canonical fold typical of alpha/beta hydrolases and a typical catalytic triad, suggesting a distinct evolutionary origin for this family. Genes in the Lipase3 family do not have the same functions, but maintain the conserved Lipase3 domain. There have been extensive studies of Lipase3 structures and functions, but little is known about their evolutionary histories. In this study, all lipases within five plant species were identified, and their phylogenetic relationships and genetic properties were analyzed and used to group them into distinct evolutionary families. Each identified lipase family contained at least one dicot and monocot Lipase3 protein, indicating that the gene family was established before the split of dicots and monocots. Similar intron/exon numbers and predicted protein sequence lengths were found within individual groups. Twenty-four tandem Lipase3 gene duplications were identified, implying that the distinctive function of Lipase3 genes appears to be a consequence of translocation and neofunctionalization after gene duplication. The functional genes EDS1, PAD4, and SAG101 that are reportedly involved in pathogen response were all located in the same group. The nucleotide diversity (Dxy) and the ratio of nonsynonymous to synonymous nucleotide substitutions rates (Ka/Ks) of the three genes were significantly greater than the average across the genomes. We further observed evidence for selection maintaining diversity on three genes in the Toll-Interleukin-1 receptor type of nucleotide binding/leucine-rich repeat immune receptor (TIR-NBS LRR) immunity-response signaling pathway, indicating that they could be vulnerable to pathogen effectors. PMID- 29468430 TI - Impaired aspirin-mediated platelet function inhibition in resuscitated patients with acute myocardial infarction treated with therapeutic hypothermia: a prospective, observational, non-randomized single-centre study. AB - The majority of resuscitated patients present with underlying cardiac disease, and out of these myocardial infarction is most common. Immediate interventional treatment is recommended and routinely requires dual antiplatelet therapy including aspirin and a P2Y12-inhibitor. Therapeutic hypothermia or target temperature management is also recommended in these patients. Cardiogenic shock as well as reduced body temperature impacts platelet reactivity and its medical inhibition. The study aims to quantify aspirin- and P2Y12-mediated platelet inhibition in patients presenting with myocardial infarction and cardiopulmonary resuscitation. Twenty-five resuscitated patients were enrolled in this prospective, observational, non-randomized single-centre study. These patients were compared to 77 matched controls from the ATLANTIS-ACS database of non resuscitated patients with myocardial infarction. Platelet function testing was performed by light transmittance aggregometry. Aspirin reactivity was monitored by inducing platelet aggregation with collagen and arachidonic acid, respectively. P2Y12 inhibition was recorded by stimulation of platelet aggregation with adenosine diphosphate. To quantify the overall platelet response, thrombin receptor-activated peptide was used. Aspirin-mediated platelet reactivity decreased significantly in resuscitated patients during the first days and was significantly weaker on day 3 (collagen AUC 253.8 (122.7-352.2) vs. 109.0 (73.0-182.0); p = 0.022). P2Y12-mediated platelet inhibition was also impaired in resuscitated patients on day 3 (mean ADP AUC (IQR): CPR 172.1 (46.7-346.5) vs. control 43.9 (18.9-115.2); p < 0.05). Aspirin- and P2Y12-mediated platelet inhibition is impaired in resuscitated patients treated with therapeutic hypothermia. On day 3, we recorded lowest inhibitory effects of both drug types and patients might be at particular risk at that time. Potentially, intravenous aspirin and P2Y12 inhibitors might still supply a more predictable and stable platelet inhibition.

AB - The molecularly imprinted polymers for gallic acid were synthesized by precipitation polymerization. During the process of synthesis a non-covalent approach was used for the interaction of template and monomer. In the polymerization process, gallic acid was used as a template, acrylic acid as a functional monomer, ethylene glycol dimethacrylate as a cross-linker and 2,2' azobisisobutyronitrile as an initiator and acetonitrile as a solvent. The synthesized imprinted and non-imprinted polymer particles were characterized by using Fourier-transform infrared spectroscopy and scanning electron microscopy. The rebinding efficiency of synthesized polymer particles was evaluated by batch binding assay. The highly selective imprinted polymer for gallic acid was MIPI1 with a composition (molar ratio) of 1:4:20, template: monomer: cross-linker, respectively. The MIPI1 showed highest binding efficiency (79.50%) as compared to other imprinted and non-imprinted polymers. The highly selective imprinted polymers have successfully extracted about 80% of gallic acid from spiked urine sample. PMID- 29468432 TI - Seed (Sperma) and Kuema in Aristotle's Generation of Animals. AB - There are two different notions of seed (sperma) at work in the Generation of Animals: seed as the spermatic residue (perittoma), which concerns only the male and the female generative contributions, and seed as the kuema and first mixture of the two generative contributions. The latter is a notion of seed common to plants and animals. The passage in GA I.18, 724b12-22 where Aristotle distinguishes between these two notions of seed has been mistakenly discredited as inauthentic or simply as irrelevant for understanding the seeds of animals. On the other hand, recent studies have rather focused on the seed as spermatic residue (in particular, the female contribution as seed), paying little attention to the notion of seed as kuema. In this paper I defend the authenticity and relevance of this passage and show how understanding the notion of seed as kuema is essential to have a complete picture of Aristotle's account of seed. This common notion of seed makes sense of Aristotle's otherwise puzzling use of the word "sperma" to designate the seeds of plants, the kuema, the fertilized eggs, and the first mixture of the two generative contributions. It also proves helpful in determining what the word 'sperma' stands for in key passages, such as Metaph. IX.7. PMID- 29468433 TI - Merging perspectives: genotype-directed molecular therapy for hereditary diffuse gastric cancer (HDGC) and E-cadherin-EGFR crosstalk. AB - Hereditary diffuse gastric cancer is a cancer predisposition syndrome associated with germline mutations of the E-cadherin gene (CDH1; NM_004360). Male CDH1 germline mutation carriers have by the age of 80 years an estimated 70% cumulative incidence of gastric cancer, females of 56% for gastric and of 42% for lobular breast cancer. Metastatic HDGC has a poor prognosis which is worse than for sporadic gastric cancer. To date, there have been no treatment options described tailored to this molecular subtype of gastric cancer. Here we review recent differential drug screening and gene expression results in c.1380del CDH1 mutant HDGC cells which identified drug classes targeting PI3K (phosphoinositide 3-kinase), MEK (mitogen-activated protein kinase), FAK (focal adhesion kinase), PKC (protein kinase C), and TOPO2 (topoisomerase II) as selectively more effective in cells with defective CDH1 function. ERK1-ERK2 (extracellular signal regulated kinase) signaling measured as top enriched network in c.1380delA CDH1 mutant cells. We compared these findings to synthetic lethality and pharmacological screening results in isogenic CDH1-/- MCF10A mammary epithelial cells with and without CDH1 expression and current knowledge of E cadherin/catenin-EGFR cross-talk, and suggest different rationales how loss of E cadherin function activates PI3K, mTOR, EGFR, or FAK signaling. These leads represent molecularly selected treatment options tailored to the treatment of CDH1-deficient familial gastric cancer. PMID- 29468434 TI - Preservation of the nipple-areola complex in skin-sparing mastectomy for early breast cancer. AB - PURPOSE: Skin-sparing mastectomy (SSM) enables a radical cure of breast cancer while overcoming the cosmetic issues related to surgery. We review our experience of performing SSMs and assess whether preservation of the nipple-areola complex (NAC) could have been an option for some patients who underwent SSM. METHODS: The subjects of this retrospective study were women who underwent SSM that utilized four incision types; namely, the so-called tennis racket incision, a periareolar and midaxillary incision, an areola-sparing and midaxillary incision, and a small transverse elliptical incision. We assessed whether preservation of the NAC would have been an option in SSM, based on histologic examination of three serial cut surfaces of the specimen around the nipple, ruling out the option when evidence of the malignant lesion/s was found in at least one of the following locations: in the nipple, within a 1-cm radius from the base of the nipple, or within 1 cm from the surface of the NAC. RESULTS: We performed 193 SSMs. The cumulative 10 year local disease-free survival rate was 98%, with 89% of patients reporting levels of satisfaction with the reconstructed breast, of excellent, very good, or good. We evaluated that 70 of the 193 procedures could have been performed as nipple-sparing mastectomy (NSM). CONCLUSIONS: The outcomes of SSM in this series were excellent and NSM might have been an option for about one-third of the patients. PMID- 29468435 TI - Additional lymph node dissection for primary colorectal cancer invading another colon region. AB - PURPOSE: Surgery remains the curative treatment of choice for colorectal cancer (CRC). However, to our knowledge, no report has addressed the usefulness of additional regional lymph node dissection for primary CRC that has invaded another colon region. METHODS: We reviewed the clinicopathological characteristics and outcomes of eight patients who underwent surgery between March, 2005 and August, 2014, for CRC that invaded another region of the colon. RESULTS: Five patients underwent additional regional lymph node dissection in the area of the invaded colon and one patient had lymph node metastasis in the region. Two of three patients who did not undergo additional regional lymph node dissection were found to have regional lymph node recurrences in the area during the follow-up period. Although there was no statistical correlation between extra regional lymph node metastasis and clinicopathological or operative factors, the patients with extra-regional lymph node metastasis or recurrence had primary regional lymph node metastasis. CONCLUSION: For curative intent, surgeons may need to perform additional regional lymph node dissection for primary CRC invading another colon region. PMID- 29468436 TI - Repair of infected mitral valves: what have we learned? AB - Infective endocarditis (IE) is associated with high mortality and morbidity and requires surgical intervention in about half of all patients. Mitral valve repair (MVrep) is reported to achieve better results than mitral valve replacement because the insertion of a prosthesis during active infection is avoided. However, MVrep in active IE is complicated and no definitive guidelines have been compiled. The current study reviews the literature from 2000 to 2016 and summarizes the surgical details of MVrep for IE. PMID- 29468437 TI - Young adults diagnosed with Hodgkin lymphoma are at risk of relapsing late: a comprehensive analysis of late relapse in Hodgkin lymphoma. AB - PURPOSE: Majority of relapses in Hodgkin lymphoma (HL) occur within 3 years after initial treatment, late relapses (LR), happening 5 or more years after first diagnosis is rare events. Neither clinical characteristics, risk factors, nor optimal treatment is well described for LR patients. Our aim was to provide a comprehensive analysis on the LR of HL to outline a patient population at risk of relapsing late. PATIENTS AND METHODS: 637 HL patients were treated at the University of Debrecen between 1981 and 2010. Patient data was evaluated retrospectively. Survival analysis was performed using the Kaplan-Meier method and odds ratios (OR) were identified by binary logistic regression models. RESULTS: With a median observational time of 9.08 years 584 (91%) HL patients achieved complete remission (CR) after first line treatment. Relapse occurred in 176 (28%) patients, 26 (4%) of them 5 or more years after first diagnosis. With multivariable analysis, initial diagnosis before the age of 24 (p < 0.001), initial presentation between 1981 and 1990 or 1991-2000 (p = 0.025 and p = 0.023, respectively) and first line treatment with radiotherapy only (p = 0.034) were identified as independent risk factors for LR. We observed a significantly impaired OS for patients with early relapse HL compared to those in long-term remission or experiencing LR (p < 0.001). CONCLUSION: Late relapse of HL presents with clinical characteristics very similar to primary disease and appears to have a good prognosis. First diagnosis in childhood or young adulthood and first line treatment before the ABVD era increases the risk of relapsing late. PMID- 29468439 TI - Theoretical investigation of the use of nanocages with an adsorbed halogen atom as anode materials in metal-ion batteries. AB - The applicability of C44, B22N22, Ge44, and Al22P22 nanocages, as well as variants of those nanocages with an adsorbed halogen atom, as high-performance anode materials in Li-ion, Na-ion, and K-ion batteries was investigated theoretically via density functional theory. The results obtained indicate that, among the nanocages with no adsorbed halogen atom, Al22P22 would be the best candidate for a novel anode material for use in metal-ion batteries. Calculations also suggest that K-ion batteries which utilize these nanocages as anode materials would give better performance and would yield higher cell voltages than the corresponding Li-ion and Na-ion batteries with nanocage-based anodes. Also, the results for the nanocages with an adsorbed halogen atom imply that employing them as anode materials would lead to higher cell voltages and better metal-ion battery performance than if the nanocages with no adsorbed halogen atom were to be used as anode materials instead. Results further implied that nanocages with an adsorbed F atom would give higher cell voltages and better battery performance than nanocages with an adsorbed Cl or Br atom. We were ultimately able to conclude that a K-ion battery that utilized Al21P22 with an adsorbed F atom as its anode material would afford the best metal-ion battery performance; we therefore propose this as a novel highly efficient metal-ion battery. Graphical abstract The results of a theoretical investigation indicated that Al22P22 is a better candidate for a high-performance anode material in metal-ion batteries than Ge44 is. Calculations also showed that K-ion batteries with nanocage-based anodes would produce higher cell voltages and perform better than the equivalent Li-ion and Na-ion batteries with nanocage-based anodes, and that anodes based on nanocages with an adsorbed F atom would perform better than anodes based on nanocages with an adsorbed Cl or Br atom. PMID- 29468438 TI - Durable treatment-free remission in patients with chronic myeloid leukemia in chronic phase following frontline nilotinib: 96-week update of the ENESTfreedom study. AB - PURPOSE: ENESTfreedom is evaluating treatment-free remission (TFR) following frontline nilotinib in patients with chronic myeloid leukemia (CML) in chronic phase. Following our primary analysis at 48 weeks, we here provide an updated 96 week analysis. METHODS: Attempting TFR required >= 3 years of nilotinib, a molecular response of MR4.5 [BCR-ABL1 <= 0.0032% on the International Scale (BCR ABL1IS)], and sustained deep molecular response (DMR) during a 1-year consolidation phase. Patients restarted nilotinib following loss of major molecular response (MMR; BCR-ABL1IS <= 0.1%). RESULTS: Ninety-six weeks after stopping treatment (3.6-year median prior nilotinib duration), 93 of 190 patients (48.9%) remained in TFR. Of 88 patients who restarted nilotinib following loss of MMR, 87 regained MMR and 81 regained MR4.5 by the data cut-off. Ninety-six-week TFR rates were 61.3, 50.0, and 28.6% in patients with low, intermediate, and high Sokal risk scores at diagnosis, respectively. Patients consistently in MR4.5 during consolidation had higher TFR rates (50.6%) than patients with >= 1 assessment without MR4.5 during consolidation (35.0%). In a landmark analysis, 96 week TFR rates for patients with MR4.5, MR4 (BCR-ABL1IS <= 0.01%) but not MR4.5, and MMR but not MR4 at TFR week 12 were 82.6, 23.1, and 0%, respectively. There were no reports of disease progression or death due to CML; overall adverse event frequency decreased following TFR. Within the follow-up period, TFR did not adversely affect disease outcomes. CONCLUSIONS: These results demonstrate the feasibility and durability of TFR following frontline nilotinib and emphasize the importance of sustained DMR for TFR. PMID- 29468440 TI - Incidence and clinical relevance of cage subsidence in anterior cervical discectomy and fusion: a systematic review. AB - BACKGROUND: The placement of intervertebral cages in anterior cervical discectomy (ACDF) supposedly maintains foraminal height. The most commonly reported cage related complication is subsidence, although it is unknown whether a correlation between subsidence and clinical outcome exists. AIM: To assess the incidence and relevance of subsidence. METHODS: Literature searches were performed in PubMed, MEDLINE, Embase, Web of Science, COCHRANE, and CENTRAL. The inclusion criteria were as follows: >= 20 patients, ADCF with cage, subsidence assessed, and primary data. Risk of bias was assessed using adjusted Cochrane checklists. RESULTS: Seventy-one studies, comprising 4784 patients, were included. Subsidence was generally defined as >= 3-mm loss of height comparing postoperative intervertebral heights with heights at last follow-up. Mean incidence of subsidence was 21% (range 0-83%). Of all patients, 46% of patients received polyether-ether-ketone (PEEK) cages, 31% received titanium cages, 18% received cage-screw-combinations, and 5% received polymethyl-methacrylate (PMMA) cages. Patients treated with cage-screw-combinations had significantly less subsidence than patients treated with PEEK, titanium, or PMMA cages (15.1% vs. 23.5% vs. 24.9% vs. 30.2%; p < 0.001). Thirteen studies assessed clinical outcome in relation to subsidence; the majority did not find a significant correlation. Only four studies correlated subsidence to cage size and/or height; no correlation was established. CONCLUSIONS: Subsidence in ACDF with cages occurs in 21% of patients. The risk for subsidence seems lower using PEEK or titanium cages or adding screws. Whether subsidence affects clinical outcome is not satisfactorily evaluated in the available literature. Future studies on this correlation are warranted in order to establish the additional value of the interposition of a cage in ACDF. PMID- 29468441 TI - A new minimally invasive technique for lead revision of perc-paddle leads. AB - To report on a less-invasive technique for replacing a broken lead in a spinal cord stimulation (SCS) device that makes use of St. Jude Medical's "Epiducer" device. A 53-year-old woman suffered a loss of stimulation on her internal pulse generator (IPG), which was found to have a broken lead. The broken lead was withdrawn using the Epiducer device with minimal invasiveness and without pain. A new lead was put in place, and successful stimulation using the IPG resumed. Follow-up 3 weeks later showed a well-functioning SCS system. An Epiducer can be used to revise the SCS system in a minimal invasive way without a new puncture. Follow-up study of this technique as well as others for revising an SCS system should be encouraged and used in comparison study. PMID- 29468443 TI - Deviations from Expectations: A Commentary on Aliev et al. PMID- 29468442 TI - A Brief Critique of the TATES Procedure. AB - The Trait-based test that uses the Extended Simes procedure (TATES) was developed as a method for conducting multivariate GWAS for correlated phenotypes whose underlying genetic architecture is complex. In this paper, we provide a brief methodological critique of the TATES method using simulated examples and a mathematical proof. Our simulated examples using correlated phenotypes show that the Type I error rate is higher than expected, and that more TATES p values fall outside of the confidence interval relative to expectation. Thus the method may result in systematic inflation when used with correlated phenotypes. In a mathematical proof we further demonstrate that the distribution of TATES p values deviates from expectation in a manner indicative of inflation. Our findings indicate the need for caution when using TATES for multivariate GWAS of correlated phenotypes. PMID- 29468444 TI - The expression of the MSC-marker CD73 and of NF2/Merlin are correlated in meningiomas. AB - Mesenchymal stem cells (MSC) have been found in various cancers and were discussed to influence tumor biology. Cells fulfilling the complete MSC criteria, including surface marker expression (CD73, CD90, CD105) and tri-lineage differentiation, have been isolated solely from a low percentage of high-grade meningiomas. In contrast, pure co-expression of the surface-markers was relatively frequent, raising the question for an additional role of these membrane proteins in meningiomas. Therefore, here we analyzed the expression of CD73, CD90 and CD105 in a series of meningiomas of all grades. Although no significant association of any marker with meningeal tumor growth per se or with tumor-grade was observed, we detected a positive Pearson correlation (r = 0.55, p <= 0.05) in low-grade tumors between CD73 and the most relevant tumor suppressor NF2/Merlin, supported by a tendency of lower CD73 expression in cases with allelic losses at the NF2-locus, which express significantly lower NF2/Merlin mRNA (p <= 0.05). In two pairs of syngenous meningeal or meningioma cell lines with or without shRNA-mediated knockdown of NF2/Merlin a nearly complete loss of CD73 mRNA expression was observed after the knockdown (p <= 0.001). This suggested that the correlation observed in tumors may result from a direct functional link between Merlin and CD73. Since CD73 is a 5'-exonucleotidase (termed NT5E), we discuss a potential role of NT5E-mediated purinergic signaling to modulate actin-cytoskeleton and cell contacts, which may be a functional link to NF2/Merlin. PMID- 29468445 TI - Tumor microenvironment after biodegradable BCNU wafer implantation: special consideration of immune system. AB - Biomaterials to treat cancers hold therapeutic potential; however, their translation to bedside treatment requires further study. The carmustine (1,3-bis (2-chloroethyl)-1-nitrosourea; BCNU) wafer, a biodegradable polymer, currently is the only drug that is able to be placed at the surgical site to treat malignant tumors. However, how this wafer affects the surrounding tumor microenvironment is not well understood to date. We retrospectively reviewed all patients with glioblastoma treated with and without BCNU wafers who underwent repeat resection at tumor recurrence. We investigated radiological imaging; the interval between the two surgeries; and immunohistochemistry of CD3, CD4, CD8, CD20, CD68, FOXP3, and PD1. We implanted BCNU wafers in 41 newly diagnosed glioblastoma patients after approval of the wafer in Japan. Of them, 14 underwent surgery at recurrence and tissue was obtained from around the wafers. The interval between the first and second surgeries ranged from 63 to 421 days. The wafer could be observed on magnetic resonance imaging at up to 226 days, whereas intraoperatively the biodegraded material of the wafer could be found at up to 421 days after the initial surgery. Immunohistochemical analysis demonstrated that CD8+ and CD68+ cells were significantly increased, but FOXP3+ cells did not increase, after wafer implantation compared to tissue from cases without wafer implantation. MRI data and immune cells, as well as interval between surgeries and immune cells, demonstrated positive correlation. These results helped us to understand the bioactivity of bioengineered materials and to establish a new approach for immunotherapy. PMID- 29468446 TI - Cost-effectiveness of the long-term use of temozolomide for treating newly diagnosed glioblastoma in Germany. AB - Concomitant radiochemotherapy followed by six cycles of temozolomide (= short term) is considered as standard therapy for adults with newly diagnosed glioblastoma. In contrast, open-end administration of temozolomide until progression (= long-term) is proposed by some authors as a viable alternative. We aimed to determine the cost-effectiveness of long-term temozolomide therapy for patients newly diagnosed with glioblastoma compared to standard therapy. A Markov model was constructed to compare medical costs and clinical outcomes for both therapy types over a time horizon of 60 months. Transition probabilities for standard therapy were calculated from randomized controlled trial data by Stupp et al. The data for long-term temozolomide therapy was collected by matching a cohort treated in the Department of Neurosurgery at Jena University Hospital. Health utilities were obtained from a previous cost utility study. The cost perspective was based on health insurance. The base case analysis showed a median overall survival of 17.1 months and a median progression-free survival of 7.4 months for patients in the long-term temozolomide therapy arm. The cost effectiveness analysis using all base case parameters in a time-dependent Markov model resulted in an incremental effectiveness of 0.022 quality-adjusted life years (QALYs). The incremental cost-effectiveness ratio (ICER) was ?351,909/QALY. Sensitivity analyses showed that parameters with the most influence on ICER were the health state utility of progression in both therapy arms. Although open-ended temozolomide therapy is very expensive, the ICER of this therapy is comparable to that of the standard temozolomide therapy for patients newly diagnosed with glioblastoma. PMID- 29468447 TI - The Views of Mental Health Manager Towards the Use of a Family Work Model for Psychosis in Guangzhou, China. AB - Family Interventions in Psychosis (FIP) have been promoted internationally but have been criticised for being based on western cultural models. This paper reports on a focus group study with 10 Integrated Mental Health Service Managers in Guangzhou, China using thematic analysis. Managers believed FIP might benefit families but identified potential difficulties due to (a) families avoiding services due to the 'shame' of mental illness (b) unrealistic expectations of services amongst families (c) deferral to 'key decision-makers' within families when discussing family issues with workers. The findings indicate that FIP work should focus on interaction between carers in the first instance with service users being introduced into sessions at a later date and that more attention needs to be given by the research community to how FIP may be adapted to cultural norms within China. PMID- 29468449 TI - Effect of Tungsten Nanolayer Coating on Si Electrode in Lithium-ion Battery. AB - Tungsten (W) was coated onto a silicon (Si) anode at the nanoscale via the physical vaporization deposition method (PVD) to enhance its electrochemical properties. The characteristics of the electrode were identified by scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray analysis, and electron probe X-ray microanalysis. With the electrochemical property analysis, the first charge capacities of the W-coated and uncoated electrode cells were 2558 mAh g- 1 and 1912 mAh g- 1, respectively. By the 50th cycle, the capacity ratios were 61.1 and 25.5%, respectively. Morphology changes in the W-coated Si anode during cycling were observed using SEM and TEM, and electrochemical characteristics were examined through impedance analysis. Owing to its conductivity and mechanical properties from the atomic W layer coating through PVD, the electrode improved its cyclability and preserved its structure from volumetric demolition. PMID- 29468448 TI - Current State of Fetal Intervention for Lower Urinary Tract Obstruction. AB - PURPOSE OF THE REVIEW: In this article, we explore the origins of intervention of fetal lower urinary tract obstruction, and we specifically discuss the background and recent outcomes of vesicoamniotic shunt placement and fetal cystoscopy. The article seeks to provide a comprehensive overview of the field while bringing the reader quickly up to speed on the pertinent literature and the critical data that are available to guide decision-making regarding intervention. RECENT FINDINGS: Appropriate patient selection for fetal intervention remains challenging despite advances in prenatal imaging. Both a randomized controlled trial and multiple systematic reviews show evidence of a perinatal survival benefit following fetal intervention but rates of renal morbidity remain very high. Despite 30 years of research, fetal lower urinary tract obstruction remains a difficulty entity to treat. Intervention may lead to survival, but physicians and caregivers must remain alert for the distinct possibility of long-term renal morbidity in survivors.

AB - Two genetically different porcine epidemic diarrhea virus (PEDV) strains have been identified in the USA: US prototype (also called non-S INDEL) and S INDEL PEDVs. In February 2017, a PEDV variant (USA/OK10240-8/2017) was identified in a rectal swab from a sow farm in Oklahoma, USA. Complete genome sequence analyses indicated this PEDV variant was genetically similar to US non-S INDEL strain but had a continuous 600-nt (200-aa) deletion in the N-terminal domain of the spike gene compared to non-S INDEL PEDVs. This is the first report of detecting PEDV bearing large spike gene deletion in clinical swine samples in the USA. PMID- 29468452 TI - Leptin regulates the pro-inflammatory response in human epidermal keratinocytes. AB - The role of leptin in cutaneous wound healing process has been suggested in genetically obese mouse studies. However, the molecular and cellular effects of leptin on human epidermal keratinocytes are still unclear. In this study, the whole-genome-scale microarray analysis was performed to elucidate the effect of leptin on epidermal keratinocyte functions. In the leptin-treated normal human keratinocytes (NHKs), we identified the 151 upregulated and 53 downregulated differentially expressed genes (DEGs). The gene ontology (GO) enrichment analysis with the leptin-induced DEGs suggests that leptin regulates NHKs to promote pro inflammatory responses, extracellular matrix organization, and angiogenesis. Among the DEGs, the protein expression of IL-8, MMP-1, fibronectin, and S100A7, which play roles in which is important in the regulation of cutaneous inflammation, was confirmed in the leptin-treated NHKs. The upregulation of the leptin-induced proteins is mainly regulated by the STAT3 signaling pathway in NHKs. Among the downregulated DEGs, the protein expression of nucleosome assembly associated centromere protein A (CENPA) and CENPM was confirmed in the leptin treated NHKs. However, the expression of CENPA and CENPM was not coupled with those of other chromosome passenger complex like Aurora A kinase, INCENP, and survivin. In cell growth kinetics analysis, leptin had no significant effect on the cell growth curves of NHKs in the normal growth factor-enriched condition. Therefore, leptin-dependent downregulation of CENPA and CENPM in NHKs may not be directly associated with mitotic regulation during inflammation.

AB - BACKGROUND: Clinical ultrasound is commonly used in medical practices worldwide due to the multiple benefits the modality offers clinicians. Rigorous credentialing standards are necessary to safeguard patients against operator errors. The purpose of the study was to establish and analyse the barriers that specifically lead to poor credentialing success within a resource-limited clinical ultrasound training programme. METHODS: An electronic cross-sectional survey was e-mailed to all trainees who attended the introductory clinical ultrasound courses held in Cape Town since its inception in 2009 to 2013. All trainees were followed until they completed their training programme in 2015. RESULTS: Only one fifth of trainees (n = 43, 19.7%), who entered the Cape Town training programme, credentialed successfully. Ninety (n = 90, 41.3%) trainees responded to the survey. Eighty-six (n = 86) surveys were included for analysis. Time constraints were the highest ranked barrier amongst all trainees. Access barriers (to trainers and ultrasound machines) were the second highest ranked amongst the non-credentialed group. A combination between access and logistical barriers (e.g. difficulty in finding patients with pathology to scan) were the second highest ranked in the credentialed group. CONCLUSIONS: Access barriers conspire to burden the Cape Town clinical ultrasound training programme. Novel solutions are necessary to overcome these access barriers to improve future credentialing success.

AB - PURPOSE: This phase II study evaluated the efficacy and safety of anastrozole concurrent with tegafur/uracil (UFT) as neoadjuvant therapy for ER-positive postmenopausal breast cancer. METHODS: Postmenopausal Japanese women with ER positive, HER2-negative, T2,N0-1,M0 breast cancer seen at tertiary hospitals were eligible for this open-label, randomized, multicenter study. Patients were randomized 1:1 by minimization to orally receive either anastrozole (1 mg once daily) plus UFT (tegafur/uracil combination in 1:4 molar ratio; 270 mg/m2/day in two divided doses) or anastrozole (as above) alone for 24 weeks. Tumor response was assessed by investigator and central review as per RECIST v1.1. The primary endpoint was the proportion of patients with best overall response of CR or PR [clinical response rate (RR)] determined by central radiologic review. RESULTS: The study was prematurely terminated due to Grade >= 3 liver dysfunction reported in 3 patients receiving anastrozole/UFT. Of 57 patients randomized before termination (29 anastrozole/UFT, 28 anastrozole), all were analyzed for safety and 56 (28 each group) for tumor response. Compared with anastrozole alone, anastrozole/UFT did not achieve significantly higher RR [39.3% (90% CI 23.8 56.5%) vs 14.3% (90% CI 5.0-29.8%); p = 0.0683, Fisher's exact test], but produced significantly greater tumor shrinkage (mean tumor reduction rate 31.0 vs. 14.2%; p = 0.0181, unpaired t-test). Grade >= 3 adverse events were more common with anastrozole/UFT than with anastrozole (17.2 vs. 0%). CONCLUSION: Although the study was terminated owing to the altered liver function, it showed that there was a trend to greater shrinkage of tumor in the combination group for ER-positive, HER2-negative postmenopausal breast cancer. PMID- 29468455 TI - Evaluation of hepatic impairment on pharmacokinetics and safety of crizotinib in patients with advanced cancer. AB - PURPOSE: This phase 1 study evaluated the effect of hepatic impairment on pharmacokinetics and safety of crizotinib in patients with advanced cancer. METHODS: Patients were dosed according to hepatic function classified by modified National Cancer Institute Organ Dysfunction Working Group criteria and group assignment [normal (A1 and A2), mild (B), moderate (C1 and C2), or severe (D)]. Primary pharmacokinetic endpoints included area under the concentration-time curve as daily exposure (AUCdaily) and maximum plasma concentration (Cmax) at steady state. Safety endpoints included types, incidence, seriousness, and relationship to crizotinib of adverse events. RESULTS: The AUCdaily and Cmax in patients with normal liver function were 7107 ng h/mL and 375.1 ng/mL (A1) and 5422 ng h/mL and 283.9 ng/mL (A2), respectively. The AUCdaily and Cmax ratios of adjusted geometric means for Groups B, C2, and D versus Group A1 were 91.12 and 91.20, 114.08 and 108.87, and 64.47 and 72.63, respectively. Any grade treatment related adverse events (TRAEs) occurred in 75% of patients; grade 3/4 TRAEs occurred in 25%, including fatigue (6%), hyponatremia (5%), and hyperbilirubinemia (3%). CONCLUSIONS: No adjustment to the approved 250 mg twice daily (BID) dose of crizotinib is recommended for patients with mild hepatic impairment. The recommended dose is 200 mg BID for patients with moderate hepatic impairment, and the dose should not exceed 250 mg daily for patients with severe hepatic impairment. Adverse events appeared consistent among the hepatic impairment groups. CLINICAL TRIAL REGISTRATION NO: NCT01576406. PMID- 29468456 TI - Phase 1, open-label, dose-escalation study of sorafenib in combination with eribulin in patients with advanced, metastatic, or refractory solid tumors. AB - Combining sorafenib and eribulin mesylate may provide synergistic antitumor activities with limited overlapping toxicities. This phase 1b, open-label, dose escalation study evaluated safety, pharmacokinetics, maximum tolerated dose/recommended phase 2 dose (MTD/RP2D), and preliminary efficacy of sorafenib plus standard-dose eribulin mesylate in patients with advanced, metastatic, or refractory tumors. Patients received sorafenib 200 mg twice daily (BID; n = 5), 600 mg/day (n = 8), and 400 mg BID (MTD; n = 27). Dose-limiting toxicities were increased alanine aminotransferase and acute coronary syndrome (both grade 3) in the 400-mg BID dose-escalation and expansion cohorts, respectively. No significant increase in mean QTcF duration was observed with eribulin plus sorafenib versus eribulin alone; there were no drug-drug interactions. Five patients achieved partial response; 16 achieved stable disease. The combination of sorafenib and eribulin mesylate presented no unexpected safety concerns and no significant impact on QT/QTc intervals or drug-drug interactions. Sorafenib 400 mg BID plus standard-dose eribulin is the RP2D. PMID- 29468457 TI - Obesity and Stress Urinary Incontinence: Impact on Pathophysiology and Treatment. AB - PURPOSE OF REVIEW: Obesity is highly prevalent and is associated with stress urinary incontinence (SUI). The purposes of this review are to assess the pathophysiology of SUI in the obese female and review the outcomes of weight loss and anti-incontinence surgery in this population. RECENT FINDINGS: While increased intra-abdominal pressure appears to be the common pathophysiologic link between obesity and SUI, neurogenic and metabolic pathways have been proposed. Both surgical and non-surgical weight loss continue to have beneficial effects on SUI; however, long-term outcomes are largely absent. Midurethral sling (MUS) surgery is largely effective in the obese population, with a complication profile similar to that in non-obese women. Obesity has been shown to be a risk factor for failure of MUS. While weight loss should be the primary modality to improve SUI in the obese woman, MUS remains an effective and safe option in those women undertaking surgery. PMID- 29468458 TI - Axon Initial Segment Structural Plasticity is Involved in Seizure Susceptibility in a Rat Model of Cortical Dysplasia. AB - Cortical dysplasia is the most common etiology of intractable epilepsy. Both excitability changes in cortical neurons and neural network reconstitution play a role in cortical dysplasia epileptogenesis. Recent research shows that the axon initial segment, a subcompartment of the neuron important to the shaping of action potentials, adjusts its position in response to changes in input, which contributes to neuronal excitability and local circuit balance. It is unknown whether axon initial segment plasticity occurs in neurons involved in seizure susceptibility in cortical dysplasia. Here, we developed a "Carmustine"- "pilocarpine" rat model of cortical dysplasia and show that it exhibits a lower seizure threshold, as indicated by behavior studies and electroencephalogram monitoring. Using immunofluorescence, we measured the axon initial segment positions of deep L5 somatosensory neurons and show that it is positioned closer to the soma after acute seizure, and that this displacement is sustained in the chronic phase. We then show that Nifedipine has a dose-dependent protective effect against axon initial segment displacement and increased seizure susceptibility. These findings further our understanding of the pathophysiology of seizures in cortical dysplasia and suggests Nifedipine as a potential therapeutic agent. PMID- 29468459 TI - Rht24 reduces height in the winter wheat population 'Solitar * Bussard' without adverse effects on Fusarium head blight infection. AB - KEY MESSAGE: The dwarfing gene Rht24 on chromosome 6A acts in the wheat population 'Solitar * Bussard', considerably reducing plant height without increasing Fusarium head blight severity and delaying heading stage. The introduction of the Reduced height (Rht)-B1 and Rht-D1 semi-dwarfing genes led to remarkable increases in wheat yields during the Green Revolution. However, their utilization also brings about some unwanted characteristics, including the increased susceptibility to Fusarium head blight. Thus, Rht loci that hold the potential to reduce plant height in wheat without concomitantly increasing Fusarium head blight (FHB) susceptibility are urgently required. The biparental population 'Solitar * Bussard' fixed for the Rht-1 wild-type alleles, but segregating for the recently described gibberellic acid (GA)-sensitive Rht24 gene, was analyzed to identify quantitative trait loci (QTL) for FHB severity, plant height, and heading date and to evaluate the effect of the Rht24 locus on these traits. The most prominent QTL was Rht24 on chromosome 6A explaining 51% of genotypic variation for plant height and exerting an additive effect of - 4.80 cm. For FHB severity three QTL were detected, whereas five and six QTL were found for plant height and heading date, respectively. No FHB resistance QTL was co localized with QTL for plant height. Unlike the Rht-1 semi-dwarfing alleles, Rht24b did not significantly affect FHB severity. This demonstrates that the choice of semi-dwarfing genes used in plant breeding programs is of utmost consideration where resistance to FHB is an important breeding target. PMID- 29468461 TI - Flavonoid intake from fruit and vegetables during adolescence is prospectively associated with a favourable risk factor profile for type 2 diabetes in early adulthood. AB - PURPOSE: Flavonoid consumption during adolescence could contribute to preventing adult onset of type 2 diabetes mellitus. We investigated the prospective association between habitual intake of flavonoids from fruit and vegetables (FlavFV) during adolescence and risk markers of type 2 diabetes in early adulthood. METHODS: This analysis included participants of the DONALD Study, who had provided a fasting blood sample in adulthood (18-39 years), data on FlavFV intake during adolescence (females: 9-15 years, males: 10-16 years) and relevant covariates. Habitual FlavFV-intake was either estimated using repeated 3-day weighed dietary records (n = 268), or the validated biomarker hippuric acid (uHA) excretion in repeated 24-h urine samples (n = 241). Multivariable linear regressions were performed to analyse the prospective associations of FlavFV or uHA with homeostasis model assessment insulin sensitivity (HOMA2-%S), hepatic steatosis index (HSI), fatty liver index (FLI) and a pro-inflammatory score. RESULTS: Higher FlavFV-intake was independently related to higher HOMA2-%S among females (Ptrend = 0.03), but not among males. Both FlavFV-intake and uHA excretion were inversely associated with HSI (Ptrend < 0.0001 and Ptrend = 0.02, respectively) and the pro-inflammatory score (Ptrend = 0.02 and Ptrend = 0.008, respectively), but not with FLI. CONCLUSIONS: Our data indicate that flavonoid consumption from fruit and vegetables during adolescence is associated with a favourable risk factor profile for type 2 diabetes in early adulthood. PMID- 29468460 TI - Two dominant loci determine resistance to Phomopsis cane lesions in F1 families of hybrid grapevines. AB - KEY MESSAGE: Rapid characterization of novel NB-LRR-associated resistance to Phomopsis cane spot on grapevine using high-throughput sampling and low-coverage sequencing for genotyping, locus mapping and transcriptome analysis provides insights into genetic resistance to a hemibiotrophic fungus. Phomopsis cane and leaf spot, caused by the hemibiotrophic fungus Diaporthe ampelina (syn = Phomopsis viticola), reduces the productivity in grapevines. Host resistance was studied on three F1 families derived from crosses involving resistant genotypes 'Horizon', Illinois 547-1, Vitis cinerea B9 and V. vinifera 'Chardonnay'. All families had progeny with extremely susceptible phenotypes, developing lesions on both dormant canes and maturing fruit clusters. Segregation of symptoms was observed under natural levels of inoculum in the field, while phenotypes on green shoots were confirmed under controlled inoculations in greenhouse. High-density genetic maps were used to localize novel qualitative resistance loci named Rda1 and Rda2 from V. cinerea B9 and 'Horizon', respectively. Co-linearity between reference genetic and physical maps allowed localization of Rda2 locus between 1.5 and 2.4 Mbp on chromosome 7, and Rda1 locus between 19.3 and 19.6 Mbp of chromosome 15, which spans a cluster of five NB-LRR genes. Further dissection of this locus was obtained by QTL mapping of gene expression values 14 h after inoculation across a subset of the 'Chardonnay' * V. cinerea B9 progeny. This provided evidence for the association between transcript levels of two of these NB-LRR genes with Rda1, with increased NB-LRR expression among susceptible progeny. In resistant parent V. cinerea B9, inoculation with D. ampelina was characterized by up-regulation of SA-associated genes and down-regulation of ethylene pathways, suggesting an R-gene-mediated response. With dominant effects associated with disease-free berries and minimal symptoms on canes, Rda1 and Rda2 are promising loci for grapevine genetic improvement. PMID- 29468462 TI - Modulation by hydroxytyrosol of oxidative stress and antitumor activities of paclitaxel in breast cancer. AB - PURPOSE: The main objective of this study was to test the therapeutic potential of hydroxytyrosol and its combination with paclitaxel in breast cancer on oxidative stress status. METHODS: Impact on proliferation rates of different chemotherapy administration patterns was assayed in MCF-7 and MDA-MB-231 breast cancer cell lines. Breast tumor-bearing rats were randomly assigned to Control, Hydroxytyrosol, Paclitaxel and Paclitaxel plus hydroxytyrosol groups, for 6 weeks. Tumor volume, cell proliferation and several systemic oxidative stress parameters were measured. Anti-proliferative activity in vitro experiments was correlated with in vivo experiments. RESULTS: Combination group did significantly reduce tumor volume when compared with paclitaxel alone. Additionally, the combination improved the antioxidant status without compromising the antitumor activity of standard chemotherapy. CONCLUSION: These findings reveal for the first time that hydroxytyrosol is an active partner in combined therapies with paclitaxel against breast cancer. Combination with hydroxytyrosol would also ensure a less oxidative impact of chemotherapeutic drugs that could potentially improve patient wellness. PMID- 29468463 TI - Detecting seasonal and cyclical trends in agricultural runoff water quality hypothesis tests and block bootstrap power analysis. AB - Seasonal and cyclic trends in nutrient concentrations at four agricultural drainage ditches were assessed using a dataset generated from a multivariate, multiscale, multiyear water quality monitoring effort in the agriculturally dominant Lower Rio Grande Valley (LRGV) River Watershed in South Texas. An innovative bootstrap sampling-based power analysis procedure was developed to evaluate the ability of Mann-Whitney and Noether tests to discern trends and to guide future monitoring efforts. The Mann-Whitney U test was able to detect significant changes between summer and winter nutrient concentrations at sites with lower depths and unimpeded flows. Pollutant dilution, non-agricultural loadings, and in-channel flow structures (weirs) masked the effects of seasonality. The detection of cyclical trends using the Noether test was highest in the presence of vegetation mainly for total phosphorus and oxidized nitrogen (nitrite + nitrate) compared to dissolved phosphorus and reduced nitrogen (total Kjeldahl nitrogen-TKN). Prospective power analysis indicated that while increased monitoring can lead to higher statistical power, the effect size (i.e., the total number of trend sequences within a time-series) had a greater influence on the Noether test. Both Mann-Whitney and Noether tests provide complementary information on seasonal and cyclic behavior of pollutant concentrations and are affected by different processes. The results from these statistical tests when evaluated in the context of flow, vegetation, and in-channel hydraulic alterations can help guide future data collection and monitoring efforts. The study highlights the need for long-term monitoring of agricultural drainage ditches to properly discern seasonal and cyclical trends. PMID- 29468464 TI - Characterizing Intervention Strategies Used in Community-Based Mental Health Care for Infants and Their Families. AB - Mental health interventions for infants typically target high-risk groups and can prevent long-term negative outcomes. Despite federal initiatives promoting early intervention, minimal research has examined usual care services for infants, which is important to improve routine care. The current study characterized usual care practices in infant mental health through the adaptation and administration of a provider survey. Providers (n = 126) reported using a wide range of intervention strategies and few intervention programs with varied evidence. Findings can inform future research to identify quality improvement targets of usual mental health care for high-risk infants and their families. PMID- 29468465 TI - ASNC President's Message. PMID- 29468466 TI - Evolving, innovating, and revolutionary changes in cardiovascular imaging: We've only just begun! AB - In this review, we highlight the need for innovation and creativity to reinvent the field of nuclear cardiology. Revolutionary ideas brought forth today are needed to create greater value in patient care and highlight the need for more contemporary evidence supporting the use of nuclear cardiology practices. We put forth discussions on the need for disruptive innovation in imaging-guided care that places the imager as a central force in care coordination. Value-based nuclear cardiology is defined as care that is both efficient and effective. Novel testing strategies that defer testing in lower risk patients are examples of the kind of innovation needed in today's healthcare environment. A major focus of current research is the evolution of the importance of ischemia and the prognostic significance of non-obstructive atherosclerotic plaque and coronary microvascular dysfunction. Embracing novel paradigms, such as this, can aid in the development of optimal strategies for coronary disease management. We hope that our article will spurn the field toward greater innovation and focus on transformative imaging leading the way for new generations of novel cardiovascular care.

PMID- 29468474 TI - Estimation of forest aboveground biomass and uncertainties by integration of field measurements, airborne LiDAR, and SAR and optical satellite data in Mexico. AB - BACKGROUND: Information on the spatial distribution of aboveground biomass (AGB) over large areas is needed for understanding and managing processes involved in the carbon cycle and supporting international policies for climate change mitigation and adaption. Furthermore, these products provide important baseline data for the development of sustainable management strategies to local stakeholders. The use of remote sensing data can provide spatially explicit information of AGB from local to global scales. In this study, we mapped national Mexican forest AGB using satellite remote sensing data and a machine learning approach. We modelled AGB using two scenarios: (1) extensive national forest inventory (NFI), and (2) airborne Light Detection and Ranging (LiDAR) as reference data. Finally, we propagated uncertainties from field measurements to LiDAR-derived AGB and to the national wall-to-wall forest AGB map. RESULTS: The estimated AGB maps (NFI- and LiDAR-calibrated) showed similar goodness-of-fit statistics (R2, Root Mean Square Error (RMSE)) at three different scales compared to the independent validation data set. We observed different spatial patterns of AGB in tropical dense forests, where no or limited number of NFI data were available, with higher AGB values in the LiDAR-calibrated map. We estimated much higher uncertainties in the AGB maps based on two-stage up-scaling method (i.e., from field measurements to LiDAR and from LiDAR-based estimates to satellite imagery) compared to the traditional field to satellite up-scaling. By removing LiDAR-based AGB pixels with high uncertainties, it was possible to estimate national forest AGB with similar uncertainties as calibrated with NFI data only. CONCLUSIONS: Since LiDAR data can be acquired much faster and for much larger areas compared to field inventory data, LiDAR is attractive for repetitive large scale AGB mapping. In this study, we showed that two-stage up-scaling methods for AGB estimation over large areas need to be analyzed and validated with great care. The uncertainties in the LiDAR-estimated AGB propagate further in the wall to-wall map and can be up to 150%. Thus, when a two-stage up-scaling method is applied, it is crucial to characterize the uncertainties at all stages in order to generate robust results. Considering the findings mentioned above LiDAR can be used as an extension to NFI for example for areas that are difficult or not possible to access. PMID- 29468475 TI - A DFT study of the catalytic pyrolysis of benzaldehyde on ZnO, gamma-Al2O3, and CaO models. AB - The catalytic pyrolysis pathways of carbonyl compounds in coal were systematically studied using density functional theory (DFT), with benzaldehyde (C6H5CHO) employed as a coal-based model compound and ZnO, gamma-Al2O3, and CaO as catalysts. The results show that the products of both pyrolysis and catalytic pyrolysis are C6H6 and CO. However, the presence of any of the catalysts changes the reaction pathway and reduces the energy barrier, indicating that these catalysts promote C6H5CHO decomposition. Graphical abstract The presence of catalysts changes the reaction pathway and the energy barrier decreases in the order Ea (no catalyst)> Ea (CaO)> Ea (gamma-Al2O3)> Ea (ZnO), indicating that these catalysts promote C6H5CHO decomposition. PMID- 29468473 TI - Clinical aspects of myocardial fibrosis in adults with Ebstein's anomaly. AB - Heart failure and arrhythmia are common complications in adults with Ebstein's anomaly. They may result not only from hemodynamic alterations, but also from myocardial fibrosis. Late gadolinium enhancement (LGE) by CMR enables the evaluation of myocardial fibrosis. The aim of the study was to asses the presence of LGE and its relation to clinical outcome. We studied a group of 37 unoperated adults aged 43.0 +/- 14.4 years with Ebstein's anomaly from the congenital heart disease outpatient clinic. Study protocol included: cardiopulmonary test, assessment of supraventricular arrhythmia (SVA), and CMR with evaluation of cardiac chambers' morphology and function, and presence of LGE. Variables following normal distribution were shown as mean +/- SD if otherwise median (range) was applied. Fibrosis was found in 18 patients (48.6%) and was distributed as follows: 12 patients (32.4%) in the right atrium, 12 (32.4%) in the atrialized right ventricle, and 2 (5.4%) in the functional right ventricle. In patients with fibrosis, the tricuspid regurgitation fraction was bigger (48.3 +/- 19.7 vs. 36.1 +/- 22.6%, p = 0.048) and SVA was more frequent [12 (66.7%) vs. 6 (31.6%), p = 0.046] when compared to patients without fibrosis. However, exercise capacity did not differ between patients with and without LGE (peak VO2 24.0 +/- 4.7 vs. 23.7 +/- 4.4, p = 0.87). In adults with Ebstein's anomaly fibrosis estimated by LGE-CMR was localized in the right atrium and the right ventricle only. Volume overload resulting from tricuspid regurgitation might be a factor conducive to fibrosis. Myocardial fibrosis did not influence exercise capacity. Association between myocardial fibrosis and supraventricular arrhythmia was confirmed. PMID- 29468476 TI - Current Treatment of Pediatric Bladder and Prostate Rhabdomyosarcoma. AB - PURPOSE OF REVIEW: Rhabdomyosarcoma (RMS) is the most common sarcoma diagnosed in the first 20 years of life; bladder/prostate (BP) RMS accounts for 5% of all cases. Through efforts from multiple cooperative study groups, survival has improved significantly. This article aims to review the complex RMS classification system and treatment of BP RMS, with a focus on developing aspects of treatment. RECENT FINDINGS: Recent advancements in technology are responsible for most of the progress in RMS treatment. PET-CT scanning has been shown to be superior to conventional metastatic workup. The use of proton beam therapy and brachytherapy to reduce the side effects of radiation is also showing promise. All cooperative oncology groups agree on surgical biopsy for diagnosis and staging of BP RMS. Patients are then grouped and risk classified before receiving chemotherapy. Regardless of local control strategy, oncologic outcomes appear to be similar for BP RMS. Alternative treatment strategies, which remain unproven, include brachytherapy and proton therapy. PMID- 29468477 TI - Ethanol extract of Rehmannia glutinosa exerts antidepressant-like effects on a rat chronic unpredictable mild stress model by involving monoamines and BDNF. AB - The dried roots of Rehmannia glutinosa Libosch. (Scrophulariaceae) are of both medicinal and nutritional importance. Our previous study has found that the 80% ethanol extract of R. glutinosa (RGEE) produced antidepressant-like activities in mouse behavioral despair depression models. However, its mechanisms are still unclear. The present study aimed to observe the antidepressant-like mechanisms of RGEE on a rat chronic unpredictable mild stress (CUMS) model by involving monoaminergic neurotransmitters and brain-derived neurotrophic factor (BDNF). CUMS-stressed rats were orally given RGEE daily (150, 300, and 600 mg/kg) or fluoxetine hydrochloride (FH) for 3 weeks after starting the CUMS procedure. Sucrose preference test was carried out to observe depression-like behavior, and serum and brain tissues were used for neurochemical and fluorescent quantitative reverse transcription PCR analysis. Results demonstrated that CUMS induced depression-like behavior, whereas RGEE and FH administration inhibited this symptom. Furthermore, CUMS caused excessively elevated levels of serum corticosterone (CORT), an index of hypothalamic-pituitary-adrenal (HPA) axis hyperactivity, in a manner attenuated by RGEE and FH administration. RGEE administration also further elevated monoamine neurotransmitters and BDNF levels, up-regulated the mRNA expression of BDNF and tropomyosin-related kinase B (TrkB) in hippocampus of rats suffering CUMS. Together, our findings suggest that RGEE can improve CUMS-evoked depression-like behavior, and indicate its mechanisms may partially be associated with restoring HPA axis dysfunctions, enhancing monoamineergic nervous systems, and up-regulating BDNF and TrkB expression. PMID- 29468478 TI - Does Trabecular Bone Score (TBS) improve the predictive ability of FRAX(r) for major osteoporotic fractures according to the Japanese Population-Based Osteoporosis (JPOS) cohort study? AB - This study examined whether bone microarchitecture determined by Trabecular Bone Score (TBS) is associated with the risk of major osteoporotic fractures independent of FRAX(r) in Japanese women. Participants included 1541 women aged >= 40 at baseline. Major osteoporotic fractures during a 10-year follow-up period were documented by the Japanese Population-based Osteoporosis Cohort Study. TBS and areal bone mineral density (aBMD) were calculated for the same spinal regions at baseline. To compare the predictive ability of FRAX(r) model when used alone versus in combination with TBS, Akaike information criterion (AIC), the area under the receiver operating characteristic curve (AUC), net reclassification improvement (NRI), and integrated discrimination improvement (IDI) were calculated. We identified 67 events of major osteoporotic fractures. The skeletal sites of the first fracture event were as follows: hip (11), vertebrae (13), radius (42), and humerus (1). The model incorporating FRAX(r) [1.35 (95% CI 1.09 1.67) for 1 standard deviation (SD) increase] with TBS [1.46 (95% CI 1.08-1.98) for 1 SD decrease] demonstrated better fit compared to a model consisting of FRAX alone (AIC 528.6 vs 532.7). NRI values for classification accuracy showed significant improvements in the FRAX(r) and TBS model, as compared to FRAX(r) alone [0.299 (95% CI 0.056-0.541)]. However, there were no significant differences in AUC or IDI between these models. The TBS score is associated with a risk of major osteoporotic fracture independent of FRAX(r) score obtained with or without BMD values among Japanese women during a 10-year follow-up period. PMID- 29468479 TI - Cell encapsulation utilizing PEG-fibrinogen hydrogel supports viability and enhances productivity under stress conditions. AB - Recent advances in the bioengineering field have introduced new opportunities enabling cell encapsulation in three-dimensional (3D) structures using either various natural or synthetic materials. However, such hydrogel scaffolds have not been fully biocompatible for cell cultivation due to the lack of physical stability or bioactivity. Here, we utilized a uniquely fabricated semi-synthetic 3D polyethylene glycol-fibrinogen (PEG-Fb) hydrogel scaffold, which exhibits both high stability and high bioactivity, to encapsulate HEK293 cells for the production of human recombinant acetylcholine esterase (AChE). To examine the beneficial bioactive effect of the PEG-Fb scaffold over 2D surfaces, an experimental system was established to compare the viability, proliferation and AChE secretion of encapsulated cells versus non-encapsulated surface-adherent cells in serum starvation. Our results show that the transfer of surface-adherent HEK293 cells from fully enriched medium with 10% FCS to 0.2% FCS resulted in an eightfold reduction in cell number and a fourfold reduction in AChE production. In contrast, the encapsulated cells were highly viable and about twofold more efficient in AChE production. In addition, they had round morphology with a twofold larger cell diameter, supporting the observation of increased AChE production. These results suggest a role of the PEG-Fb scaffold in providing a supportive microenvironment in reduced serum conditions that enhances encapsulated cell functions, opening new directions to study the implementation of this platform in large-scale pharmaceutical protein production.

We address the dynamics of changes which may occur within minutes, but may also last weeks, depending on the species and conditions. Two different modes of changes are suggested, i.e. stepwise and gradual. A switch between two distinct environments (e.g. host plant switch by phytophagous insects) results in stepwise formation of two distinct adaptive phenotypes, while a gradual environmental change (e.g. temperature gradients) induces a gradual change of numerous adaptive CHC phenotypes. We further discuss the ecological and evolutionary consequences of phenotypic plasticity of insect CHC profiles by addressing the question at which conditions is CHC phenotypic plasticity beneficial. The high plasticity of CHC profiles might be a trade-off for insects using CHCs for communication. We discuss how insects cope with the challenge to produce and "understand" a highly plastic, environmentally dependent CHC pattern that conveys reliable and comprehensible information. Finally, we outline how phenotypic plasticity of CHC profiles may promote speciation in insects that rely on CHCs for mate recognition.

AB - Lung cancer has a relatively poor prognosis with a low survival rate and drugs that target other cell death mechanism like autophagy may help improving current therapeutic strategy. This study investigated the anti-proliferative effect of Licarin A (LCA) from Myristica fragrans in non-small cell lung cancer cell lines A549, NCI-H23, NCI-H520 and NCI-H460. LCA inhibited proliferation of all the four cell lines in a dose and time dependent manner with minimum IC50 of 20.03 +/- 3.12, 22.19 +/- 1.37 uM in NCI-H23 and A549 cells respectively. Hence NCI-H23 and A549 cells were used to assess the ability LCA to induce autophagy and apoptosis. LCA treatment caused G1 arrest, increase in Beclin 1, LC3II levels and degradation of p62 indicating activation of autophagy in both NCI-H23 and A549 cells. In addition, LCA mediated apoptotic cell death was confirmed by MMP loss, increased ROS, cleaved PARP and decreased pro-caspase3. To understand the role of LCA induced autophagy and its association with apoptosis, cells were analysed following treatment with a late autophagy inhibitor-chloroquine and also after Beclin 1 siRNA transfection. Data indicated that inhibition of autophagy resulted in reduced anti-proliferative as well as pro-apoptotic ability of LCA. These findings confirmed that LCA brought about autophagy dependent apoptosis in non small cell lung cancer cells and hence it may serve as a potential drug candidate for non-small cell lung cancer therapy. PMID- 29468482 TI - Epirubicin induces apoptosis in osteoblasts through death-receptor and mitochondrial pathways. AB - Epirubicin is an anthracycline and is widely used in tumor treatment, but has toxic and undesirable side effects on wide range of cells and hematopoietic stem cells (HSC). Osteoblasts play important roles in bone development and in supporting HSC differentiation and maturation. It remains unknown whether epirubicin-induced bone loss and hematological toxicity are associated with its effect on osteoblasts. In primary osteoblast cell cultures, epirubicin inhibited cell growth and decreased mineralization. Moreover, epirubicin arrested osteoblasts in the G2/M phase, and this arrest was followed by apoptosis in which both the extrinsic (death receptor-mediated) and intrinsic (mitochondrial mediated) apoptotic pathways were evoked. The factors involved in the extrinsic apoptotic pathway were increased FasL and FADD as well as activated caspase-8. Those involved in the intrinsic apoptotic pathway were decreased Bcl-2; increased reactive oxygen species, Bax, cytochrome c; and activated caspase-9 and caspase 3. These results demonstrate that epirubicin induced osteoblast apoptosis through the extrinsic and intrinsic apoptotic pathways, leading to the destruction of osteoblasts and consequent lessening of their functions in maintaining bone density and supporting hematopoietic stem cell differentiation and maturation. PMID- 29468483 TI - Elimination of Bimodal Size in InAs/GaAs Quantum Dots for Preparation of 1.3-MUm Quantum Dot Lasers. AB - The device characteristics of semiconductor quantum dot lasers have been improved with progress in active layer structures. Self-assembly formed InAs quantum dots grown on GaAs had been intensively promoted in order to achieve quantum dot lasers with superior device performances. In the process of growing high-density InAs/GaAs quantum dots, bimodal size occurs due to large mismatch and other factors. The bimodal size in the InAs/GaAs quantum dot system is eliminated by the method of high-temperature annealing and optimized the in situ annealing temperature. The annealing temperature is taken as the key optimization parameters, and the optimal annealing temperature of 680 degrees C was obtained. In this process, quantum dot growth temperature, InAs deposition, and arsenic (As) pressure are optimized to improve quantum dot quality and emission wavelength. A 1.3-MUm high-performance F-P quantum dot laser with a threshold current density of 110 A/cm2 was demonstrated. PMID- 29468484 TI - Seek and you shall find... multiple truths. PMID- 29468485 TI - Characterization of a novel breast cancer cell line derived from a metastatic bone lesion of a breast cancer patient. AB - PURPOSE: We aimed to generate and characterize a novel cell line from a breast cancer bone metastasis to better study the progression of the disease. METHODS: The cell line, P7731, was derived from a metastatic bone lesion of a breast cancer patient and assessed for marker expression. P7731 was analyzed for DNA copy number variation, somatic mutations, and gene expression and was compared with the primary tumor. RESULTS: P7731 cells are negative for estrogen receptor alpha (ERalpha), progesterone receptor (PR), and HER2 (triple-negative); strongly express vimentin (100% of cells positive) and also express cytokeratins 8/18 and 19 but at lower frequencies. Flow cytometry indicates P7731 cells are predominantly CD44+/CD49f+/EpCAM-, consistent with a primitive, mesenchymal-like phenotype. The cell line is tumorigenic in immunocompromised mice. Exome sequencing identified a total of 45 and 76 somatic mutations in the primary tumor and cell line, respectively, of which 32 were identified in both samples and included mutations in known driver genes PIK3CA, TP53, and ARID1A. P7731 retains the DNA copy number alterations present in the matching primary tumor. Homozygous deletions detected in the cell line and in the primary tumor were found in regions containing three known (CDKN2A, CDKN2B, and CDKN1B) and 23 putative tumor suppressor genes. Cell line-specific gene amplification coupled with mRNA expression analysis revealed genes and pathways with potential pro-metastatic functions. CONCLUSION: This novel human breast cancer-bone metastasis cell line will be a useful model to study aspects of breast cancer biology, particularly metastasis-related changes from breast to bone. PMID- 29468486 TI - Tumor-associated macrophages and crown-like structures in adipose tissue in breast cancer. AB - PURPOSE: We aimed to evaluate macrophage infiltration and to identify the status of crown-like structures (CLSs) in mammary adipose tissue of human breast tissue in cases with and without breast cancer. METHODS: Breast adipose tissue was obtained from reduction mammoplasty (N = 56, Group 1), non-neoplastic breast tissue of breast cancer patients (N = 84, Group 2), and breast cancer with adipose stroma (N = 140, Group 3). Immunohistochemical staining of CD68 and CD163 was performed, and the infiltrating macrophages and CLSs within breast adipose tissue were evaluated. RESULTS: Group 3 had the largest number of CD68-positive (CD68+) and CD163-positive (CD163+) macrophages and CLSs within adipose tissue (P < 0.001). Among Group 3, cases with high levels of CD68+ and CD163+ macrophages commonly had a higher histologic grade (P = 0.016 and P = 0.045), and cases with CD163+ CLSs were correlated with old age (P = 0.042), estrogen receptor negativity (P = 0.013), human epidermal growth factor receptor-2 positivity (P = 0.043), and non-luminal A type (P = 0.039). Upon univariate analysis, high levels of CD163+ macrophages were associated with shorter disease-free survival in node negative breast cancer patients (P = 0.033), and CD68+ CLSs were associated with shorter overall survival in node-positive breast cancer patients (P = 0.015). CONCLUSIONS: CD68+ and/or CD163+ tumor-associated macrophage infiltration as well as CLSs are present in adipose tissue nearby the breast cancer lesion, and are associated with various clinicopathologic parameters of breast cancer. PMID- 29468487 TI - 68Ga-DOTATATE PET-CT imaging in carotid body paragangliomas. AB - OBJECTIVE: The aim of this study was to present our experience in the baseline evaluation of carotid body paragangliomas (CBP) with 68Ga-DOTATATE PET-CT. METHODS: Five patients (4F, 1M; age 24-73 years) with CBPs who underwent 68Ga DOTATATE PET-CT scan before the treatment were evaluated retrospectively. PET-CT images were analyzed visually as well as semiquantitatively, with measurement of maximum standardized uptake value (SUVmax). RESULTS: All patients had unilateral CBP lesion, showed intense 68Ga-DOTATATE uptake in PET-CT. Additionally, 68Ga DOTATATE avid lesions were found in two patients. One of them had focal intense uptake in thyroid gland and frontal cerebrum. The other one had intense uptake in bone and adrenal mass. Four patients were operated for unilateral primary CBP. Last patient was treated with peptide receptor radionuclide therapy (177Lu DOTATATE) for both metastatic pheochromocytoma and CBP. CONCLUSIONS: 68Ga DOTATATE PET-CT is a valuable imaging modality for staging of CBPs, detecting unknown lesions and changing the management of patients. It is also useful in demonstrating expression of SSTRs for PRRT opportunity. PMID- 29468489 TI - 2018 Letter from the Editor in Chief. PMID- 29468488 TI - TV viewing and incident venous thromboembolism: the Atherosclerotic Risk in Communities Study. AB - TV viewing is associated with risk of arterial vascular diseases, but has not been evaluated in relation to venous thromboembolism (VTE) risk in Western populations. In 1987-1989, the Atherosclerosis Risk in Communities Study obtained information on the frequency of TV viewing in participants aged 45-64 and followed them prospectively. In individuals free of prebaseline VTE (n = 15, 158), we used a Cox proportional hazards models to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) of incident VTE according to frequency of TV viewing ("Never or seldom", "Sometimes", "Often" or "Very often"). During the 299,767 person-years of follow-up, we identified 691 VTE events. In a multivariable-adjusted model, the frequency of TV viewing showed a positive dose response relation with VTE incidence (P for trend = 0.036), in which "very often" viewing TV carried 1.71 (95% CI 1.26-2.32) times the risk of VTE compared with "never or seldom" viewing TV. This association to some degree was mediated by obesity (25% mediation, 95% CI 10.7-27.5). Even among individuals who met a recommended level of physical activity, viewing TV "very often" carried 1.80 (1.04-3.09) times the risk of VTE, compared to viewing TV "never or seldom". Greater frequency of TV viewing was independently associated with increased risk of VTE, partially mediated by obesity. Achieving a recommended physical activity level did not eliminate the increased VTE risk associated with frequent TV viewing. Avoiding frequent TV viewing as well as increasing physical activity and controlling body weight might be beneficial for VTE prevention. PMID- 29468491 TI - Prenatal diagnosis of mediastinal neurenteric cyst: a case report and review of the literature. AB - Neurenteric cyst is a very rare developmental anomaly. Prenatal diagnosis of mediastinal neurenteric cysts has been reported rarely. We present a case of neurenteric cyst associated with vertebral anomalies diagnosed by prenatal ultrasonography at 31 weeks of gestation, which was treated successfully in the early neonatal period. In addition, we searched the English literature for all cases of mediastinal neurenteric cyst diagnosed in the prenatal period reported to date. We found that only 17 cases were reported previously. We reviewed the reports of these 17 patients along with our case, and we investigated the prenatal and postnatal diagnosis and treatment approaches and the factors influencing the prognosis. Fetuses with mediastinal neurenteric cysts should be monitored regularly by ultrasonography. Fetuses with no signs of hydrops are more likely to survive with proper neonatal center transfer, regular follow-up, and appropriate postnatal approach. Fetuses with hydrops findings have a high risk of fetal and neonatal death. PMID- 29468490 TI - Negative pressure wound therapy reduces the motility of Pseudomonas aeruginosa and enhances wound healing in a rabbit ear biofilm infection model. AB - Pseudomonas aeruginosa motility, virulence factors and biofilms are known to be detrimental to wound healing. The efficacy of negative pressure wound therapy (NPWT) against P. aeruginosa has been little studied, either in vitro or in vivo. The present study evaluated the effect of negative pressure (NP) on P. aeruginosa motility in vitro, and the effect of NPWT on virulence factors and biofilms in vivo. P. aeruginosa motility was quantified under different levels of NP (atmospheric pressure, - 75, - 125, - 200 mmHg) using an in vitro model. Swimming, swarming and twitching motility were significantly inhibited by NP (- 125 and - 200 mmHg) compared with atmospheric pressure (p = 0.05). Virulence factors and biofilm components were quantified in NPWT and gauze treated groups using a rabbit ear biofilm model. Biofilm structure was studied with fluorescence microscopy and scanning electron microscopy. Additionally, viable bacterial counts and histological wound healing parameters were measured. Compared with the control, NPWT treatment resulted in a significant reduction in expression of all virulence factors assayed including exotoxin A, rhamnolipid and elastase (p = 0.01). A significant reduction of biofilm components (eDNA) (p = 0.01) was also observed in the NPWT group. The reduction of biofilm matrix was verified by fluorescence- and scanning electron-microscopy. NPWT lead to better histologic parameters (p = 0.01) and decreased bacterial counts (p = 0.05) compared with the control. NPWT treatment was demonstrated to be an effective strategy to reduce virulence factors and biofilm components, which may explain the increased wound healing observed. PMID- 29468492 TI - Exchange Sex Among Persons Who Inject Drugs in the New York Metropolitan Area: The Importance of Local Context, Gender and Sexual Identity. AB - Exchanging sex for money or drugs is known to increase risk for HIV among persons who inject drugs (PWID). To better understand determinants of exchange sex among PWID we examined factors associated with exchange sex in the New York metropolitan area-defined as New York City (NYC), NY; Newark, NJ; and Long Island, NY-using data from the 2012 National HIV Behavioral Surveillance system cycle on injection drug use. Of the 1160 PWID in this analysis, 24% reported exchange sex, with differences in gender and sexual identity by location. In multivariable analysis gay/bisexual men, heterosexual women, and lesbian, gay, or bisexual (LGB) women were more likely to exchange sex compared to heterosexual men. Exchange sex was also associated with race/ethnicity, homelessness, incarceration, location, and non-injection crack and cocaine use. We find that heterosexual women and LGB women who injected drugs residing in Newark were more likely to report exchange sex compared to NYC. This study highlights how local conditions impact exchange sex. PMID- 29468494 TI - Census Tract Poverty and Racial Disparities in HIV Rates in Milwaukee County, Wisconsin, 2009-2014. AB - Previous work has documented associations between poverty and HIV. Understanding of these relationships at local levels could help target prevention efforts; however, HIV surveillance systems do not capture individual-level poverty measures. We utilized the Public Health Disparities Geocoding Project methods to examine HIV rates by census tract poverty. HIV rates and rate ratios were computed by census tract poverty (< 5.0, 5.0-9.9, 10.0-19.9, > 20.0% of individual below the federal poverty level) for all races and stratified by Black and White race using Poisson regression. We observed higher HIV rates in the highest poverty gradient compared to the lowest poverty gradient for all races combined and among White cases. After adjustment, HIV rates were similar across poverty gradients for all comparisons. Our findings suggest that the association between poverty and HIV may differ by subpopulation, while demonstrating the potential for HIV prevention targeting residents of high poverty areas. PMID- 29468495 TI - Alertness and cognitive control: Toward a spatial grouping hypothesis. AB - A puzzling interaction involving alertness and cognitive control is indicated by the finding of faster performance but larger congruency effects on alert trials (on which alerting cues are presented before the task stimuli) than on no-alert trials in selective attention tasks. In the present study, the author conducted four experiments to test hypotheses about the interaction. Manipulation of stimulus spacing revealed a difference in congruency effects between alert and no alert trials for narrowly spaced stimuli but not for widely spaced stimuli, inconsistent with the hypothesis that increased alertness is associated with more diffuse attention. Manipulation of color grouping revealed similar differences in congruency effects between alert and no-alert trials for same-color and different color groupings of targets and distractors, inconsistent with the general hypothesis that increased alertness is associated with more perceptual grouping. To explain the results, the author proposes that increased alertness is associated specifically with more spatial grouping of stimuli, possibly by modulating the threshold for parsing stimulus displays into distinct objects. PMID- 29468493 TI - Facilitators and Barriers to Pre-Exposure Prophylaxis (PrEP) Use Among Black Individuals in the United States: Results from the National Survey on HIV in the Black Community (NSHBC). AB - This study explores willingness to use PrEP among Black individuals in the US. From February to April 2016, an online survey was administered to a nationally representative sample of Black individuals. 855 individuals who were HIV negative by self-report participated [mean age: 33.6 (SD 9.2); 45.5% male]. Among all respondents, 14.5% were aware of, and 26.0% would be willing to use PrEP. Among high-risk individuals (N = 327), 19.8% knew about and 35.1% would be willing to use PrEP. The most common reason for lack of willingness among high-risk individuals was low self-perceived risk (65.1%). In multivariate analysis, individuals reporting single marital status [OR 1.8 (1.2, 2.5), p = 0.002], depressive symptoms [OR 1.6 (1.2, 2.2), p = 0.0054], arrest history [OR 1.7(1.2, 2.4), p = 0.0003], PrEP knowledge [OR 1.5 (1.0, 2.3), p = 0.0247] and belief in HIV conspiracies [OR 1.3 (1.1, 1.5), p = 0.0075] were more willing to use PrEP. Participants who saw a health care provider less frequently were less willing to use PrEP [OR 0.5 (0.4, 0.8), p = 0.0044]. Among a nationally representative sample of Black individuals, few high risk individuals were willing to use PrEP. Interventions to increase risk awareness, PrEP knowledge and access to care are necessary to improve PrEP uptake. PMID- 29468496 TI - Assessing the role of accuracy-based feedback in value-driven attentional capture. AB - Despite being physically nonsalient and task-irrelevant, objects rendered in a color that once signaled monetary reward reflexively capture attention during visual search, a phenomenon known as value-driven attentional capture (VDAC). However, it remains a subject of empirical controversy whether learned reward associations are necessary to driving subsequent attentional capture: VDAC-like effects have been observed when accuracy-based feedback alone was used during the VDAC training phase, resulting in attentional capture by objects that were never associated with monetary reward; perplexingly, the presence of these VDAC-like effects in the literature conflicts with those of a number of control studies in which no such capture has been observed, leaving the issue currently unresolved. In this Registered Report, we present new empirical evidence of attentional capture by unrewarded former targets following limited accuracy-based training. We proposed to replicate these results in an independent sample and to test an empirically derived hypothesis concerning a methodological difference between the studies that have shown VDAC-like effects with accuracy-based feedback and those that have not. In short, we found no evidence that this methodological difference accounts for the inconsistencies in the literature, but our replication efforts were overwhelmingly successful, thus reinvigorating debate about the role that selection history may play in value-driven attentional capture. PMID- 29468497 TI - Effectiveness of Integrating Simulation with Art-Based Teaching Strategies on Oncology Fellows' Performance Regarding Breaking Bad News. AB - The task of breaking bad news (BBN) may be improved by incorporating simulation with art-based teaching methods. The aim of the present study was to assess the effect of an integrating simulation with art-based teaching strategies, on fellows' performance regarding BBN, in Iran. The study was carried out using quasi-experimental methods, interrupted time series. The participants were selected from medical oncology fellows at two teaching hospitals of Tehran University of Medical Sciences (TUMS), Iran. Participants were trained through workshop, followed by engaging participants with different types of art-based teaching methods. In order to assess the effectiveness of the integrating model, fellows' performance was rated by two independent raters (standardized patients (SPs) and faculty members) using the BBN assessment checklist. This assessment tool measured seven different domains of BBN skill. Segmented regression was used to analyze the results of study. Performance of all oncology fellows (n = 19) was assessed for 228 time points during the study, by rating three time points before and three time points after the intervention by two raters. Based on SP ratings, fellows' performance scores in post-training showed significant level changes in three domains of BBN checklist (B = 1.126, F = 3.221, G = 2.241; p < 0.05). Similarly, the significant level change in fellows' score rated by faculty members in post-training was B = 1.091, F = 3.273, G = 1.724; p < 0.05. There was no significant change in trend of fellows' performance after the intervention. Our results showed that using an integrating simulation with art-based teaching strategies may help oncology fellows to improve their communication skills in different facets of BBN performance.

AB - Autism is a neurodevelopmental disorder characterized by deficits in qualitative impairments in communication, repetitive and social interaction, restricted, and stereotyped patterns of behavior. Resveratrol has been extensively studied pharmacologically and biologically and has anti-inflammatory, antioxidant, and neuroprotective effects on neuronal damage in neurodegenerative disorders. The BTBR T+ Itpr3tf/J (BTBR) autistic mouse model has been explored for treatment of autism, which shows low reciprocal social interactions, impaired juvenile play, and decreased social approach. Here, we explored whether resveratrol treatment decreases neuroimmune dysregulation mediated through toll-like receptor (TLR4) and nuclear factor-kappaB (NF-kappaB) signaling pathway in BTBR mice. We investigated the effect of resveratrol treatment on TLR2, TLR3, TLR4, NF-kappaB, and inducible nitric oxide synthase (iNOS or NOS2) levels in CD4 spleen cells. We also assessed the effect of resveratrol treatment on TLR2, TLR3, TLR4, NF-kappaB, iNOS, and cyclooxygenase (COX-2) mRNA expression levels in the brain tissue. We further explored TLR2, TLR4, NF-kappaB, iNOS, and COX-2 protein expression levels in the brain tissue. Resveratrol treatment on BTBR mice significantly decreased CD4+TLR2+, CD4+TLR3+, CD4+TLR4+ CD4+NF-kappaB+, and CD4+iNOS+ levels in spleen cells. Resveratrol treatment on BTBR mice decreased TLR2, TLR3, TLR4, NF-kappaB, iNOS, and COX-2 mRNA expression levels in brain tissue. Moreover, resveratrol treatment resulted in decreased protein expression of TLR2, TLR3, TLR4, NF kappaB, iNOS, and COX-2 in brain tissue. Taken together, these results indicate that resveratrol treatment improves neuroimmune dysregulation through the inhibition of proinflammatory mediators and TLRs/NF-kappaB transcription factor signaling, which might be help devise future therapies for neuroimmune disorders. PMID- 29468500 TI - SIMS of Organic Materials-Interface Location in Argon Gas Cluster Depth Profiles Using Negative Secondary Ions. AB - A procedure has been established to define the interface position in depth profiles accurately when using secondary ion mass spectrometry and the negative secondary ions. The interface position varies strongly with the extent of the matrix effect and so depends on the secondary ion measured. Intensity profiles have been measured at both fluorenylmethyloxycarbonyl-L-pentafluorophenylalanine (FMOC) to Irganox 1010 and Irganox 1010 to FMOC interfaces for many secondary ions. These profiles show separations of the two interfaces that vary over some 10 nm depending on the secondary ion selected. The shapes of these profiles are strongly governed by matrix effects, slightly weakened by a long wavelength roughening. The matrix effects are separately measured using homogeneous, known mixtures of these two materials. Removal of the matrix and roughening effects give consistent compositional profiles for all ions that are described by an integrated exponentially modified Gaussian (EMG) profile. Use of a simple integrated Gaussian may lead to significant errors. The average interface positions in the compositional profiles are determined to standard uncertainties of 0.19 and 0.14 nm, respectively, using the integrated EMG function. Alternatively, and more simply, it is shown that interface positions and profiles may be deduced from data for several secondary ions with measured matrix factors by simply extrapolating the result to Xi = 0. Care must be taken in quoting interface resolutions since those measured for predominantly Gaussian interfaces with Xi above or below zero, without correction, appear significantly better than the true resolution. Graphical Abstract ?. PMID- 29468501 TI - Resolution and Assignment of Differential Ion Mobility Spectra of Sarcosine and Isomers. AB - Due to their central role in biochemical processes, fast separation and identification of amino acids (AA) is of importance in many areas of the biomedical field including the diagnosis and monitoring of inborn errors of metabolism and biomarker discovery. Due to the large number of AA together with their isomers and isobars, common methods of AA analysis are tedious and time consuming because they include a chromatographic separation step requiring pre- or post-column derivatization. Here, we propose a rapid method of separation and identification of sarcosine, a biomarker candidate of prostate cancer, from isomers using differential ion mobility spectrometry (DIMS) interfaced with a tandem mass spectrometer (MS/MS) instrument. Baseline separation of protonated sarcosine from alpha- and beta-alanine isomers can be easily achieved. Identification of DIMS peak is performed using an isomer-specific activation mode where DIMS- and mass-selected ions are irradiated at selected wavenumbers allowing for the specific fragmentation via an infrared multiple photon dissociation (IRMPD) process. Two orthogonal methods to MS/MS are thus added, where the MS/MS(IRMPD) is nothing but an isomer-specific multiple reaction monitoring (MRM) method. The identification relies on the comparison of DIMS MS/MS(IRMPD) chromatograms recorded at different wavenumbers. Based on the comparison of IR spectra of the three isomers, it is shown that specific depletion of the two protonated alpha- and beta-alanine can be achieved, thus allowing for clear identification of the sarcosine peak. It is also demonstrated that DIMS-MS/MS(IRMPD) spectra in the carboxylic C=O stretching region allow for the resolution of overlapping DIMS peaks. Graphical Abstract ?. PMID- 29468502 TI - Gas Flow and Ion Transfer in Heated ESI Capillary Interfaces. AB - Transfer capillaries are the preferred means to transport ions, generated by electrospray ionization, from ambient conditions to vacuum. During the transfer of ions through the narrow, long tubes into vacuum, substantial losses are typical. However, recently it was demonstrated that these losses can be avoided altogether. To understand the experimental observation and provide a general model for the ion transport, here, we investigate the ion transport through capillaries by numerical simulation of interacting ions. The simulation encompasses all relevant factors, such as space charge, diffusion, gas flow, and heating. Special attention is paid to the influence of the gas flow on the transmission and especially the change imposed by heating. The gas flow is modeled by a one-dimensional gas dynamics description. A large number of ions are treated as point particles in this gas flow. This allows to investigate the influence of the capillary heating on the gas flow and by this on the ion transport. The results are compared with experimental findings. Graphical Abstract ?. PMID- 29468503 TI - Abnormal lipid metabolism in a rat model of arthritis: one possible pathway. AB - Collagen-induced arthritis (CIA) animal model is associated with systemic manifestations, including alteration of lipid metabolism. In the present study, one possible pathway of altered lipid metabolism is proposed. Specimens of joint tissue and plasma were collected from the CIA and control rats, and quantitative analysis of lipid components was performed by nuclear magnetic resonance (NMR) spectroscopy technique. Correlation analysis was performed between the level of lipid components and antioxidant enzymes, lactate dehydrogenase (LDH), lipid peroxidation (LP), and cytokines in joint tissue and plasma. Differentiation between the CIA and control rats was established on the basis of the quantity of lipid components in the joint tissue and plasma. Positive correlation was observed for all the enzymes vs. lipid components as well as LP vs. lipid components in plasma and joint tissue. Positive correlation was observed for enzymes in plasma and joint tissue. A negative correlation was observed in between the plasma and joint tissue with the level of lipid components. Cytokine levels were also correlated with the level of lipid components and ratios of saturated fatty acids/unsaturated fatty acids in plasma and joint tissue. Inflammatory disease activity in CIA rats with synovitis brought about a significant change in lipid metabolism. Taken together, the results of our study are delineating a possible pathway of altered lipid metabolism in the CIA rat model, thereby contributing further to an understanding of the pathophysiology of rheumatoid arthritis (RA). PMID- 29468504 TI - MCAM knockdown impairs PPARgamma expression and 3T3-L1 fibroblasts differentiation to adipocytes. AB - We investigated for the first time the expression of melanoma cell adhesion molecule (MCAM) and its involvement in the differentiation of 3T3-L1 fibroblasts to adipocytes. We found that MCAM mRNA increased subsequent to the activation of the master regulator of adipogenesis, PPARgamma, and this increase was maintained in the mature adipocytes. On the other hand, MCAM knockdown impaired differentiation and induction of PPARgamma as well as expression of genes activated by PPARgamma. However, events that precede and are necessary for early PPARgamma activation, such as C/EBPbeta induction, beta-catenin downregulation, and ERK activation, were not affected in the MCAM knockdown cells. In keeping with this, the increase in PPARgamma mRNA that precedes MCAM induction was not altered in the knockdown cells. In conclusion, our findings suggest that MCAM is a gene upregulated and involved in maintaining PPARgamma induction in the late but not in the early stages of 3T3-L1 fibroblasts adipogenesis. PMID- 29468505 TI - A Cross-Cultural Perspective on the Relationships between Emotional Separation, Parental Trust, and Identity in Adolescents. AB - Emotional separation and parental trust in parent-adolescent relationships are important factors for adolescent identity formation. However, prior research findings on emotional separation are inconsistent. This study aimed to conduct a more rigorous examination of the associations of emotional separation and parental trust with identity synthesis, confusion, and consolidation by applying a bi-factor model to identity, using adolescent samples from Lithuania (N = 610; 53.9% female; M age = 14.92), Italy (N = 411; 57.4% female; M age = 15.03), and Japan (N = 759; 43.7% female; M age = 14.13). Structural equation modeling revealed that emotional separation and parental trust were consistently associated with identity consolidation across the three countries, rather than associated with identity synthesis and identity confusion. Furthermore, the patterns of associations of emotional separation and parental trust with identity synthesis and identity confusion differed across the three nations. Overall, this study provides a better understanding of the role of emotional separation and parental trust in adolescent identity formation by suggesting the importance of the identity consolidation in the association between parent-child relationships and identity formation across three countries. PMID- 29468506 TI - Dimensions of Short-Term and Long-Term Self-Regulation in Adolescence: Associations with Maternal and Paternal Parenting and Parent-Child Relationship Quality. AB - Relatively little is known about the degree to which subcomponents of self regulation change during early to middle adolescence. This study considered familial predictors (maternal/paternal regulatory support, antagonistic parenting, and parent-child closeness) of rank-order change in behavioral, emotional and cognitive regulation and perseverance over one year. N = 452 adolescents ages 11-16 years and their parents completed questionnaires and parent-child discussion tasks (48.7% male; 69.6% white). Results indicated minimal direct effects of parenting, though maternal and paternal parenting and parent-child closeness exerted small effects that were moderated by prior levels of cognitive regulation and perseverance. Parents may contribute to the development of complex regulatory capacities that mature after foundational emotional and behavioral regulation competencies. PMID- 29468507 TI - Impact of clinical factors and UGT1A9 and CYP2B6 genotype on inter-individual differences in propofol pharmacokinetics. AB - PURPOSE: Propofol is one of the most widely used fast-acting intravenously administered anesthetics. However, although large inter-individual differences in dose requirements and recovery time have been observed, there are few previous studies in which the association between several potential covariates, including genetic factors such as the UGT1A9 and CYP2B6 genotypes, and propofol pharmacokinetics was simultaneously examined. This study aimed to identify factors determining propofol pharmacokinetics. METHODS: Eighty-three patients were enrolled, and their blood samples were collected 1, 5, 10, and 15 min after administering a single intravenous bolus of propofol at a dose of 2.0 ml/kg to measure propofol plasma concentration. Area under the time-plasma concentration curve from zero up to the last measurable time point (AUC15min) was determined from the concentration data. The inter-individual variability of the propofol pharmacokinetics was evaluated by investigating relationships between AUC15min and genotype of UGT1A9 and CYP2B6; clinical factors, such as age, sex, body mass index (BMI), and preoperative hematological examination; and hemodynamic variables measured by a pulse dye densitogram analyzer. The Spearman rank correlation coefficient and the Mann-Whitney U test were used for the statistical analysis of continuous and categorical values, respectively. Subsequently, clinical factors that had p values of < 0.05 in the univariate analysis were examined in a multivariate analysis using multiple linear regression analysis. RESULTS: Age, BMI, indocyanine green disappearance ratio (K-ICG), hepatic blood flow (HBF), preoperative hemoglobin level, and sex were correlated with AUC15min (p < 0.05) in univariate analysis. Multivariate analysis performed to adjust for age, BMI, K-ICG, HBF, preoperative hemoglobin level, and sex revealed only BMI as an independent factor associated with AUC15min. CONCLUSIONS: This study demonstrated that BMI influences propofol pharmacokinetics after its administration as a single intravenous injection, while UGT1A9 and CYP2B6 SNPs, other clinical factors, and hemodynamic variables do not. These results suggest that BMI is an independent factor associated with propofol pharmacokinetics in several potential covariates.

PMID- 29468508 TI - Ultrasound-guided bilateral superficial cervical block and preemptive single-dose oral tizanidine for post-thyroidectomy pain: a randomized-controlled double-blind study. AB - PURPOSES: The postoperative analgesic effect of tizanidine has not yet been evaluated sufficiently. The role of bilateral superficial cervical plexus block (BSCPB) for postoperative analgesia after thyroidectomy remains questionable. We aimed to evaluate the analgesic effect of combined use of BSCPB and a single-dose oral tizanidine in patients undergoing elective thyroid surgery. METHODS: Sixty patients undergoing thyroidectomy were randomized into 3 groups. The control group (Group C, n = 20) received BSCPB with 0.9% saline plus oral placebo. The superficial cervical group (Group SC, n = 20) received BSCPB with 0.25% bupivacaine plus oral placebo. The superficial cervical and tizanidine group (Group SC + T, n = 20) received BSCPB with 0.25% bupivacaine plus tizanidine 6 mg capsule. Surgical site pain scores, opioid consumption, rescue analgesia, posterior neck pain, headache, and opioid-related side effects were assessed for the first 24 h. RESULTS: Compared with Group C, rest and swallowing pain scores in Group SC and Group SC + T were statistically lower at all postoperative time points (p < 0.05). Fentanyl consumption was lower in Group SC and Group SC + T than in Group C at time periods 0-4 and 4-8 h (p < 0.05). Fentanyl consumption was lower in Group SC + T than in Group SC at 0-4 h (p = 0.006). Total fentanyl consumption was higher in Group C than in the other groups (p < 0.001). Postoperative cervical pain and occipital headache were significantly lower in Group SC + T than in the other groups (p < 0.05). CONCLUSIONS: Ultrasound-guided BSCPB with or without preemptive oral tizanidine was effective at reducing postoperative pain and opioid consumption in patients undergoing total thyroidectomy. Addition of preemptive oral tizanidine to BSCPB reduced the early postoperative opioid consumption, posterior neck pain, and occipital headache.

AB - Research is limited on the health of foreign-born Blacks (FBBs), who are often grouped with African Americans. This study compared obesity and diabetes odds in FBBs and US-born Blacks (USBBs) in NYC. Analyzing the 2009-2013 NYC Community Health Survey (3701 FBBs and 6297 USBBs), weighted multivariate logistic regression examined odds of obesity and diabetes, adjusting for age, gender, education, income, marital status, children < 18, BMI (for diabetes only) and duration of residence. FBBs had lower odds of obesity [OR 0.62 (95% CI 0.54, 0.72)] and greater odds of diabetes [OR 1.24 (95% CI 1.01, 1.52)] compared to USBBs. FBBs had 1.4 times the odds of diabetes at overweight status, compared to USBBs [OR 1.40 (95% CI 1.01, 1.95)]. Living in the US >= 10 years was not associated with odds of obesity and diabetes. Future research should seek to uncover unique risk profiles of sub-ethnic groups in the African diaspora. PMID- 29468516 TI - A Systematic Review of Cognition in Chiari I Malformation. AB - Displacement of the cerebellar tonsils in Chiari type I malformation (CMI) can affect functions controlled by the cerebellum and brainstem. While playing an integral role in the control of movement, the cerebellum also has widespread cortical connections, influencing a range of cognitive process. A systematic literature review was conducted to examine the relationship between cognition and CMI, assessing evidence for general or domain-specific cognitive change. The search protocol examined the AMED, CINAHL, Cochrane Library, EMBASE, MEDLINE, PsycINFO, and Scopus databases. Articles meeting the following criteria were included in this review (i) examined children or adults with a clinically defined diagnosis of CMI, (ii) assessed cognitive function with a prospective examination, (iii) included at least one standardized instrument designed to measure general or specific domains of cognitive function, and (iv) were published in English in a peer-reviewed journal. Twelve articles were identified, including 783 cases aged 3 months to 64 years. General cognition, processing speed, and learning and memory appeared less affected, while language deficits appeared to diminish with age. Executive dysfunction was the most commonly reported cognitive impairment, while attention and working memory, and visuospatial and perceptual skills also appeared vulnerable. Numerous methodological limitations were identified that should be considered in interpreting the impact of CMI and planning future investigations. Overall, there is currently insufficient evidence to describe a valid and reliable profile of cognitive impairment in CMI. Further research is required to confirm these preliminary psychometric results and integrate them with pathophysiological models. PMID- 29468518 TI - Cultural Factors Influencing Osteoarthritis Care in Asian Communities: A Review of the Evidence. AB - With the prevalence of osteoarthritis (OA) increasing internationally, there is a need to study the impact of this disease on culturally diverse populations. Individuals of Asian descent make up more than 60% of the world population, yet comprehensive information on the cultural factors that impact OA care is not available. Scoping review methodology using directed content analysis was employed to identify and analyze existing research on OA care for Asians. A categorization matrix was developed using the six care areas from the OA clinical practice guidelines along with an additional three non-clinical areas (cross cultural adaptation of clinical tools; psychological well-being; family systems and informal care) identified in an initial scan resulting in a total of nine OA care areas to guide initial coding. A full scoping review was conducted across five databases resulting in 656 abstracts screened. All text was coded using the categorization matrix and resulting subthemes were identified. A total of 74 articles were analyzed with 23 subthemes identified across the nine categories. Four new perspectives emerged to support OA care for Asian populations: (1) the importance of family and peer assistance, (2) the importance of culturally specific activities, (3) distrust in western medicine, and (4) impact of positive coping mechanisms on health appraisals. While Asians are more susceptible to knee and hand OA because of their cultural lifestyle factors (e.g. squatting for chores, hygiene and religious activities), and traditional beliefs on OA management (e.g. traditional diet, topical oils, physical therapy), many do not present themselves for conventional treatments (e.g. surgery) until all traditional treatments are exhausted. The results suggest that cultural factors influence the uptake of OA management practices among Asians. Greater awareness of these cultural factors may improve diagnosis, treatment, and management of OA among Asian patients. PMID- 29468519 TI - Effect of Pressure Support Ventilation on Carboxyhemoglobin Toxicokinetic after Acute Carbon Monoxide Intoxication: a Swine Model. AB - INTRODUCTION: In an experimental study on carbon monoxide (CO) exposure in swine, we aimed to compare the influence of oxygen therapy using a non-rebreathing mask (NRM) to continuous positive airway pressure (CPAP) and two pressure support ventilation (PSV) devices on the decrease of the terminal elimination half-life of carboxyhemoglobin (COHb t1/2). This was the primary outcome. METHODS: Eight spontaneously breathing pigs were sedated by propofol and exposed to 940 ppm CO several times (n = 25) to obtain COHb levels of 30%. CPAPb (high flow open system, CPAP Boussignac(r) [7.5 cmH2O]), PSV-Vy (open system, Vylife Boussignac(r)), and PSV-Leg (closed system, Legendair(r) [inspiratory/expiratory airway pressure 12/4 cmH2O]) devices were used in a randomized order and compared to NRM (O2 at 15 l min-1) and atmospheric air (AA). The primary outcome was COHb t1/2. Multiple comparisons were performed using Dunn's tests. RESULTS: Median FiO2 and minute ventilation were significantly higher in the PSV-Leg group than the NRM group (p < 0.05). Median COHb t1/2 was 251, 85, 82, 93, and 58 min for AA, NRM, CPAPb, PSV-Vy, and PSV-Leg, respectively. All the interventions were superior to AA in terms of CO elimination (p < 0.001), but there was no statistically significant difference between CPAP or PSV and NRM. There was only a trend between PSV-Leg and NRM (p = 0.18). The median AUCs for ln (COHb) * time (h) were 170, 79, 83, 100, and 64 for AA, NRM, CPAPb, PSV-Vy, and PSV-Leg respectively, with a statistically significant difference only between AA and PSV Leg (p = 0.002). CONCLUSION: In conclusion, in our study on CO intoxication in swine, the use of the closed PSV-Leg system led to the shortest COHb t1/2. These results suggest that PSV-Leg can be more efficient than NRM in eliminating CO and support the design of a clinical study to assess this hypothesis. PMID- 29468520 TI - Impact of Di-2-Ethylhexyl Phthalate Metabolites on Male Reproductive Function: a Systematic Review of Human Evidence. AB - PURPOSE OF REVIEW: The purpose of this review is to systematically review the literature linking di-2-ethylhexyl phthalate (DEHP) exposure with effects on reproductive health in adult males. RECENT FINDINGS: Thirty-three papers were included of which 28 were cross-sectional. Twenty-one papers investigated semen samples, 18 investigated reproductive hormones, and three studies investigated time to pregnancy. Studies revealed some but inconsistent indications that higher urinary DEHP metabolite levels are associated with an increase in the proportion of spermatozoa with damaged DNA and to a decrease in sperm concentration and motility. A negative association between DEHP metabolites and testosterone levels was more consistent. DEHP metabolites do not seem to be associated with a delay in time to pregnancy, but data are sparse. The studies on DEHP exposure and reproductive biomarkers in men converge to support the hypothesis that DEHP exposure is related to impaired male reproductive function. Longitudinal studies are needed to establish if the observed associations are causal. PMID- 29468521 TI - Identification of a Constitutively Active Mutant Mouse IRAK2 by Retroviral Expression Screening. AB - To identify the importance of IRAK2 kinase activity in TLR-mediated signaling pathways, we constructed a retroviral vector harboring either a mouse IRAK2 gene (IRAK2-WT) or with its mutant with loss of function of its ATP-binding site (IRAK2-KD). Further, we comparatively analyzed for the gain of function and modulations in TLR-mediated signaling pathways in IRAK2 knockout (IRAK2-KO) macrophages upon introduction of the IRAK2-WT retroviral constructs. The pBS/IRAK2-KD with the ATP-binding site mutation in IRAK2 was obtained by using site-specific mutagenesis. The recombinants were identified with appropriate double digestion and sequence analysis. The recombinant vector constructs were transfected by lipofection into phoenix packaging cells. The viral vectors (107 cfu/mL) with the construct were allowed to infect IRAK2-KO macrophages. The results showed that IRAK2-WT gene overexpressed in the IRAK2-KO macrophages exhibited a modified IRAK2 expression upon LPS induction. However, the modification was absent with IRAK2-KD construct on LPS stimulation; instead, the IRAK2 protein stability was reduced considerably. The results further show that the LPS-induced effect on the stability of IRAK2 is dependent of IRAK4 stimulation. PMID- 29468522 TI - Mechanism of evolution by genetic assimilation : Equivalence and independence of genetic mutation and epigenetic modulation in phenotypic expression. AB - Conrad H. Waddington discovered the phenomenon of genetic assimilation through a series of experiments on fruit flies. In those experiments, artificially exerted environmental stress induced plastic phenotypic changes in the fruit flies, but after some generations, the same phenotypic variant started to appear without the environmental stress. Both the initial state (where the phenotypic changes were environmentally induced and plastic) and the final state (where the phenotypic changes were genetically fixed and constitutive) are experimental facts. However, it remains unclear how the environmentally induced phenotypic change in the first generation becomes genetically fixed in the central process of genetic assimilation itself. We have argued that the key to understanding the mechanism of genetic assimilation lies in epigenetics, and proposed the "cooperative model" in which the evolutionary process depends on both genetic and epigenetic factors. Evolutionary simulations based on the cooperative model reproduced the process of genetic assimilation. Detailed analysis of the trajectories has revealed genetic assimilation is a process in which epigenetically induced phenotypic changes are incrementally and statistically replaced with multiple minor genetic mutations through natural selection. In this scenario, epigenetic and genetic changes may be considered as mutually independent but equivalent in terms of their effects on phenotypic changes. This finding rejects the common (and confused) hypothesis that epigenetically induced phenotypic changes depend on genetic mutations. Furthermore, we argue that transgenerational epigenetic inheritance is not required for evolution by genetic assimilation. PMID- 29468523 TI - Gender differential in social and economic predictors of incident major depressive disorder in the Ibadan Study of Ageing. AB - PURPOSE: Working on the hypothesis that the social and economic factors associated with onset of late-life depression operate differently for men and women, we investigated the impact of current social relationships and lifetime occupational attainment on incident major depressive disorder (MDD) assessed in three follow-up waves over a period of 5 years. METHODS: Participants were part of a household multistage probability sample of 2149 Nigerians who were aged 65 years and above. The presence of current and lifetime MDD was assessed using the World Health Organization (WHO) Composite International Diagnostic Interview. Participants' highest occupational attainment was categorised based on the International Standard Classification of Occupations, while socio-economic positions were estimated using asset-based measures relevant to low-income settings. Current social contacts and participation were assessed using items from the WHO Disability Assessment Schedule. RESULTS: We found an incidence rate of 120.9 per 1000 persons years (95% CI = 110.4-132.5) among 1394 persons who were free of lifetime MDD and dementia at baseline. Incidence rates were 94.7 (95% CI = 82.5-108.7) and 153.8 (136.3-173.6) per 1000 person years, in men and women respectively. In analyses comparing gender and adjusting for the effect of age, we found that while a lifetime of unskilled occupation (trade: HR = 1.4, 95% CI = 1.0-2.0, and elementary occupations: HR = 1.5, 95% CI = 1.1-2.1) was significantly associated with incident MDD in men (but not in women), living in a rural location (HR = 1.3, 95% CI = 1.0-1.7) and having no regular contact with family (HR = 2.2, 95% CI = 1.0-4.7) at baseline significantly predicted subsequent onset of MDD in women. CONCLUSION: There was a gender differential in the association of social and economic factors with incident MDD in this sample. These findings have implications for the design of early prevention strategies for late-life depression in sub-Saharan Africa. PMID- 29468524 TI - TAFRO syndrome with refractory thrombocytopenia responding to tocilizumab and romiplostim: a case report. AB - Thrombocytopenia, anasarca, fever, reticulin fibrosis, organomegaly (TAFRO) syndrome is a unique clinicopathologic subtype of multicentric Castleman's disease that has recently been identified in Japan. However, little is known about its renal histological changes and the optimal treatment for TAFRO syndrome. An 80-year-old Japanese woman was admitted to our hospital for evaluation of severe anasarca and weight gain (10 kg in a month). She had polyneuropathy, monoclonal plasma cell proliferative disorder with positive kappa M-protein, a sclerotic bone lesion, elevation of vascular endothelial growth factor (VEGF), skin changes, and extravascular volume overload, which fulfilled the diagnostic criteria for POEMS (polyneuropathy, organomegaly, endocrinopathy, and monoclonal protein, skin changes) syndrome. However, kappa-type M-protein and thrombocytopenia with positivity of platelet-associated immunoglobulin G antibody were unusual, and fitted the diagnostic criteria for TAFRO syndrome. Renal biopsy showed diffuse endocapillary proliferative glomerulonephritis with endothelial swelling and the infiltration of monocytes and neutrophils without specific immunoglobulin deposits. Her systemic symptoms were refractory to initial treatment with high-dose melphalan and glucocorticoids. Alternative therapy with an anti-interleukin-6 (IL-6) receptor antibody (tocilizumab) effectively controlled the symptoms, while a thrombopoietin receptor agonist (romiplostim) was effective for her thrombocytopenia. Results suggest that IL-6-VEGF axis and an autoimmune mechanism may be responsible for TAFRO syndrome with clinical features of POEMS and refractory thrombocytopenia, which can be successfully treated with combination of tocilizumab and romiplostim. PMID- 29468525 TI - Valproic Acid Promotes Apoptosis and Cisplatin Sensitivity Through Downregulation of H19 Noncoding RNA in Ovarian A2780 Cells. AB - Cisplatin resistance is one of the main limitations in the treatment of ovarian cancer, which is partly mediated by long noncoding RNAs (lncRNAs). H19 is a lncRNA involving in cisplatin resistance in cancers. Valproic acid (VPA) is a commonly used drug for clinical treatment of seizure disorders. In addition, this drug may display its effects through regulation of noncoding RNAs controlling gene expression. The aim of the present study was the investigation of VPA treatment effect on H19 expression in ovarian cancer cells and also the relation of the H19 levels with apoptosis and cisplatin resistance. Briefly, treatment with VPA not only led to significant increase in apoptosis rate, but also increased the cisplatin sensitivity of A2780/CP cells. We found that following VPA treatment, the expression of H19 and EZH2 decreased, but the expression of p21 and PTEN increased significantly. To investigate the involvement of H19 in VPA-induced apoptosis and cisplatin sensitivity, H19 was inhibited by a specific siRNA. Our results demonstrate that H19 knockdown by siRNA induced apoptosis and sensitized the A2780/CP cells to cisplatin-induced cytotoxicity. These data indicated that VPA negatively regulates the expression of H19 in ovarian cancer cells, which subsequently leads to apoptosis induction, cell proliferation inhibition, and overwhelming to cisplatin resistance. The implication of H19 >EZH2->p21/PTEN pathway by VPA treatment suggests that we could repurpose an old drug, valproic acid, as an effective drug for treatment of ovarian cancer in the future. PMID- 29468526 TI - Attention deficit hyperactivity disorder pharmacotherapy in Slovenian adults: a population-based study. AB - Background Pharmacotherapy is the first line treatment for adult attention deficit hyperactivity disorder (ADHD) and the percentage of treated patients may indicate the quality of treatment of adult ADHD. The main aim of this study was to investigate the rates of pharmacological treatment for adult ADHD in Slovenia from 2003 to 2015. Methods The number of prescriptions per patient was obtained for three different age groups (18-24, 25-49, 50 + age group). The national consumption rates were obtained from the national database. The only drugs that were available and were included in this study were methylphenidate (MPH) and atomoxetine (ATX). Results Between 2003 and 2015 the rate of patients aged 18-24 who were treated with MPH increased from 0.8 per 10,000 people aged 18-24 to 8.9 per 10,000 people, while the increase in the other two age groups was less substantial (25-49, 50 + age group). The rate of patients aged 18-24 treated with ATX in 2015 was 7.3 per 10,000 people and 2.2 per 10,000 people in the 25-49 age category and 0.28 in the 50 + age group category. Conclusion Prescription rates of ADHD medication have increased dramatically in the study period. The high proportion of ADHD patients treated with ATX can be explained by low adherence to treatment guidelines. This is the first study to compare ADHD pharmacotherapy across different adult age groups in this part of Europe, so the results could be widely relevant. PMID- 29468527 TI - Collaborative practice agreement in solid organ transplantation. AB - Background Given the complexity of solid organ transplant recipients, a multidisciplinary approach is required. To promote medication safety and enable providers to focus on the medical and surgical needs of these patients, our department of pharmacy created a collaborative practice agreement between physicians and pharmacists. Through this agreement, credentialed pharmacists are empowered to provide inpatient services including initiation and adjustment of medications through independent review of laboratory results after multidisciplinary rounds. Objective To evaluate the effect of our collaborative practice agreement on clinical care and institutional finances. Setting An inpatient setting at a large academic medical center. Methods Three transplant pharmacists entered all clinical interventions made on abdominal transplant recipients between September and October 2013 into Quantifi(r), a software application that categorizes and assigns a cost savings value based on impact and type of intervention. Main outcome measure The main outcome measures in this study were number and categorization of interventions, as well as estimated cost savings to the institution. Results There were 1060 interventions recorded, an average of 20 interventions per pharmacist per day. The most common interventions were pharmacokinetic evaluations (36%) and dose adjustments (19%). Over the time period, these interventions translated into an estimated savings of $107,634.00, or an annual cost savings of $373,131.20 per pharmacist, or a cost-benefit ratio of 2.65 to the institution. Conclusions Based on our study, implementation of a collaborative practice agreement enables credentialed pharmacists to make clinically and financially meaningful interventions in a complex patient population. PMID- 29468528 TI - The influence of pharmacist-led adherence support on glycaemic control in people with type 2 diabetes. AB - Background Adherence to treatment is important to achieve target outcomes, particularly for those with type 2 diabetes. Pharmacists are well placed to enhance adherence, however evidence of the impact on clinical outcomes is not well known. Objective To determine the impact of an adherence support service on adherence scores and subsequent clinical biomarkers (HbA1c). Setting Community pharmacies providing a Medicines Use Review (MUR) Service in a New Zealand locality. Methods Records of patients receiving MURs between 2007 and 2012 were obtained from a single locality. Data extraction included: individual characteristics, the adherence score assigned at every consultation, pathology records. Patients receiving oral hypoglycaemic medications (n = 86) were included in the final analysis using generalised estimating equations to explore change in HbA1c over time, and whether this was related to the adherence score. Main Outcome Measures (a) change in adherence scores and (b) association between adherence sores and HbA1c. Results A total of 350 records were obtained, of those, 115 of 350 people had follow up MUR visit/s and could be analysed for changes in adherence. Most people (110/115) showed sustained or improved adherence scores with follow up visits. For those receiving oral hypoglycaemic medications (n = 86); where poor adherence scores were recorded, their HbA1c levels were higher and continued to increase by ~ 0.1% (1 mmol/mol) every 10 weeks, B = 0.11, p = 0.009. Conversely, those with high adherence scores showed an overall decrease in HbA1c levels. Conclusion MURs may positively influence medication adherence. This improved adherence shows a measurable decline in HbA1c levels. PMID- 29468529 TI - Right Ventricular Dysfunction and Its Contribution to Morbidity and Mortality in Left Ventricular Heart Failure. AB - PURPOSE: In patients with left-sided HF, there has been less emphasis on the pathophysiology of the RV in terms of diagnostic evaluation and treatment, versus focus on structural abnormalities of the LV. This review seeks to delineate the importance of RV dysfunction in terms of its contribution to symptomatic limitations and cardiovascular outcomes in patients with left-sided HF. RECENT FINDINGS: Recent studies have demonstrated that RV dysfunction is common in both HFpEF and HFrEF, but more pronounced in HFrEF. LV dysfunction and atrial fibrillation are most commonly associated with RV dysfunction in left-sided HF. RV dysfunction may develop due to afterload-dependent and afterload-independent pathways. Regardless, RV dysfunction is strongly associated with functional limitations and worsened survival in patients with left-sided HF. In patients with HFpEF, a recent study showed that RV failure was the most common cause of overall mortality. Among LVAD patients and patients post-cardiac transplantation, RV dysfunction is also strongly associated with survival. Despite a number of previous and ongoing clinical trials that target the RV directly or decrease RV afterload in left-sided HF, there are no definitive therapies specifically targeting RV dysfunction in left-sided HF patients CONCLUSIONS: RV dysfunction is an important determinant of symptomatic limitations and cardiovascular outcomes in patients with left-sided HF. Further research is needed to developed pharmacotherapy that may target the RV specifically in left-sided HF patients. PMID- 29468530 TI - The Future of Biomarker-Guided Therapy for Heart Failure After the Guiding Evidence-Based Therapy Using Biomarker Intensified Treatment in Heart Failure (GUIDE-IT) Study. AB - PURPOSE OF REVIEW: Biomarker-guided management of patients with chronic heart failure with reduced ejection fraction (HFrEF) remains controversial. RECENT FINDINGS: Biomarkers have established roles for diagnosis and prognostication in HF. Pilot data suggested that use of natriuretic peptides might be helpful to guide HF care. The recent Guiding Evidence-Based Therapy Using Biomarker Intensified Treatment in Heart Failure (GUIDE-IT) randomized-controlled trial did not find therapy guided by NT-proBNP to be more effective than usual care in improving the primary endpoint of HF hospitalization or cardiovascular mortality amongst patients with chronic HFrEF. Patients in GUIDE-IT received similar care and had similar NT-proBNP lowering regardless of treatment allocation. Though biomarkers retain important standing for diagnosis and prognosis in HF, the GUIDE IT trial results suggest carefully managed patients may not benefit from a biomarker-guided strategy. Future studies focusing this intervention on patients treated in a more real-world setting are needed.

PMID- 29468532 TI - Meta-analyses of HIV prevention interventions targeting improved partner communication: effects on partner communication and condom use frequency outcomes. AB - Behavioral HIV prevention interventions designed to improve safer-sex communication skills with sexual partners may enhance engagement in protective behaviors and reduce HIV/STI risk. The current meta-analyses examined the efficacy of individual-based (i.e., not couples-based) HIV prevention interventions with a partner communication skills building component to increase frequency of: (a) safer-sex communication and (b) condom use with sexual partners among HIV at-risk groups (e.g., heterosexual African American females). Studies were retrieved from online bibliographic databases, a database of effective behavioral HIV prevention interventions, and an existing review of effective interventions. Eight manuscripts (k = 10 intervention vs. control comparisons) met inclusion criteria. Results indicated that compared to control conditions, at post-intervention follow-up, participants who were exposed to individual-based HIV prevention interventions with safer-sex communication skills training components had safer sex discussions with partners more frequently [drandom = 0.35 +/- 0.10, p < .001, 95% CI (0.16, 0.55)], and used condoms more frequently [drandom = 0.39 +/- 0.07, p < .001, 95% CI (0.25, 0.54)]. Including partner communication skills training in individual-based HIV prevention interventions may increase the frequency of both partner communication and condom use among the at-risk populations represented in the meta-analyses. PMID- 29468533 TI - Recalled early life adversity and pain: the role of mood, sleep, optimism, and control. AB - Early life adversity (ELA) has been associated with pain symptomatology in adulthood, but mechanisms and moderators of these associations are unclear. Using recall based and concurrently assessed self-report data, we examined associations between ELA, mood, sleep, and recent pain intensity and interference, and whether optimism and perceived control weakened these associations in a midlife community sample of diverse adults reporting some ELA. Controlling for demographic variables and BMI, higher levels of ELA were associated with more pain intensity and interference; greater sleep disturbance and negative mood accounted for these associations. When moderation was examined, only the path from sleep disturbance to pain interference was significantly attenuated for those with higher optimism and higher perceived control. These findings suggest that higher levels of ELA may link with pain in adulthood through poorer mood and sleep, and that resilience resources such as optimism and control may buffer some of these pathways. PMID- 29468535 TI - Methodological Implications and Repeatability of Nasal Nitric Oxide: Relevance for Challenge Studies. AB - There is an interest in assessing changes in nasal NO (nNO) levels as an effect marker of upper airways. In this study, we examined methodologic influences on short and long term repeatability of nNO levels assessed by a portable electrochemical analyzer. Nine atopic and eighteen healthy subjects were exposed for 4 h to ethyl acrylate concentration of 0.05 ppm (sham) and mean concentrations of 5 ppm (either constant 5 ppm or variable 0 to 10 ppm). Sampling of nNO was performed by using passive aspiration during both breath-holding (634 ppb) or calm tidal breathing (364 ppb, p < 0.0001). The intra-session (between session) repeatability in terms of coefficient of variation was 16.4% (18.5%) using the tidal-breathing and 8.6% (13.0%) using the breath-holding method, respectively. Atopic subjects demonstrated a significant increase in nNO (breath holding mean 16%, tidal-breathing mean 32%) after applying a constant ethyl acrylate concentration (5 ppm). Our findings suggest that the less elaborate tidal-breathing method might be sufficient to detect significant changes at a group level. Given a lower coefficient of variation of breath-holding we assume there is an advantage of that approach at an individual level.

The correct title should read: "Comment to article: "Image-guided thermal ablation of benign thyroid nodules" by A. Mainini, et al. J Ultrasound (2017) https://doi.org/10.1007/s40477-016-0221-6 ". PMID- 29468534 TI - Body Covering and Body Image: A Comparison of Veiled and Unveiled Muslim Women, Christian Women, and Atheist Women Regarding Body Checking, Body Dissatisfaction, and Eating Disorder Symptoms. AB - Although Islam is the fastest growing religion worldwide, only few studies have investigated body image in Muslim women, and no study has investigated body checking. Therefore, the present study examined whether body image, body checking, and disordered eating differ between veiled and unveiled Muslim women, Christian women, and atheist women. While the groups did not differ regarding body dissatisfaction, unveiled Muslim women reported more checking than veiled Muslim and Christian women, and higher bulimia scores than Christian. Thus, prevention against eating disorders should integrate all women, irrespective of religious affiliation or veiling, with a particular focus on unveiled Muslim women.

AB - In chronic lymphatic leukemia (CLL), detection and characterization of prognostic relevant chromosomal alterations is optimally done by interphase-fluorescence in situ hybridization (iFISH). Interphase nuclei derived from blood smears, bone marrow smears or from cultivated and conventionally prepared blood or bone marrow cells can be used. In CLL heterozygous or even homozygous deletion of RB1 can be found. Interestingly an iFISH diagnostic result with RB1 deletion as sole aberration is indicative for a favorable course of the disease. Here we describe the best way how to detect RB1 deletion in CLL. PMID- 29468537 TI - Hepatitis A Virus Disinfection in Water by Solar Photo-Fenton Systems. AB - This study evaluates and compares the effectiveness of solar photo-Fenton systems for the inactivation of hepatitis A virus (HAV) in water. The effect of solar irradiance, dark- Fenton reaction and three different reactant concentrations (2.5/5, 5/10 and 10/20 mg/L of Fe2+/H2O2) on the photo-Fenton process were tested in glass bottle reactors (200 mL) during 6 h under natural sunlight. Disinfection kinetics were determined both by RT-qPCR and infectivity assays. Mean water temperatures ranged from 25 to 27.3 degrees C, with a maximum local noon UV irradiances of 22.36 W/m2. Photo-Fenton systems yielded increased viral reduction rates in comparison with the isolated effect under the Fenton reaction in darkness (negligible viral reduction) or the solar radiation (0.25 Log of RNA reduction). With the highest concentration employed (10-20 mg/L Fe2+-H2O2), an average RNA reduction rate of ~ 1.8 Log (initial concentration of 105 pfu/mL) and a reduction of 80% in the infectivity capacity were reached. Results showed a strong synergistic effect between Fe2+/H2O2 and sunlight, demonstrating that significant disinfection rates of HAV under photo-Fenton systems may occur with relatively higher efficiency at middle environmental temperatures and without the need for an energy-intensive light source.

AB - Multiplex ligation-dependent probe amplification (MLPA) is based on simultaneous multiplex PCR of specific probes that hybridize to multiple different target DNA regions. The method can identify copy number changes, gross gene rearrangements, methylation patterns or even point mutations. MLPA has been a reliable approach to identify copy number changes in the clinical and research settings and is widely used for the screening and investigation of copy number variations and genomic aberrations of interest in various diseases. In this chapter the analysis of the copy number changes in the RB1 gene locus by MLPA is described. PMID- 29468540 TI - A Fluorescent Quantitative Multiplex PCR Method to Detect Copy Number Changes in the RB1 Gene. AB - Copy number changes comprising deletions or insertions involving single or multiple exons of a gene are known to occur in a significant proportion of cases in retinoblastoma. The protocol described here involves a two-step quantitative multiplex PCR process which is suitable for the detection of such mutations in the RB1 as well as in other genes. This is achieved through the use of suitable gene-specific primers designed to amplify individual exons, with universal tags attached to the 5' end of each primer. These tagged primers are used in the first step of PCR of the RB1 gene in patients. The second step is carried out through the use of "universal" primers complementary to the tag sequences alone. This technique facilitates the detection of fluorescent PCR products from multiple exons through the use of a single fluorescent tagged primer. PMID- 29468541 TI - Using Methylation-Specific PCR to Study RB1 Promoter Hypermethylation. AB - It has increasingly been considered crucial the understanding of DNA methylation of Tumor Suppressor Gene (TSG) promoters, such as that of retinoblastoma 1 gene (RB1), and its role during carcinogenesis. We present a detailed and optimized protocol of the methylation-specific PCR (MSP) technique to study RB1 gene promoter hypermethylation. PMID- 29468542 TI - Detection of Aberrant DNA Methylation Patterns in the RB1 Gene. AB - The retinoblastoma protein (pRb) plays a central role in the regulation of cell cycle by interaction with members of the E2F transcription factor family. As a tumor suppressor protein, pRb is frequently dysregulated in several major cancers. In addition to mutations, inactivation of pRb is also caused by epigenetic mechanisms including alterations of DNA methylation. There are three CpG islands located within the RB1 gene that encodes pRb that are closely associated with the regulation of pRb expression. Aberrant DNA methylation at the RB1 gene has been reported in sporadic retinoblastoma as well as other cancers including glioblastoma, hepatocellular carcinoma, and breast cancer. Recent studies have revealed that the RB1 gene is imprinted. Therefore, quantitative analysis is required to detect aberrations in DNA methylation associated with imprint deregulation. Pyrosequencing(r) is considered as the method of choice for quantitative and reproducible analysis of DNA methylation with single base resolution. In this chapter, we provide a detailed protocol for the quantitative analysis of RB1 gene methylation using bisulfite Pyrosequencing(r). PMID- 29468543 TI - Detection of Retinoblastoma Protein Phosphorylation by Immunoblot Analysis. AB - The retinoblastoma tumor suppressor protein (pRb) is a preeminent tumor suppressor that acts as a cell cycle repressor, specifically as an inhibitor of the G1-S transition of the cell cycle . pRb is a phosphoprotein whose function is repressed by extensive phosphorylation in several key residues, and therefore, pRb's phosphorylation status has become a surrogate for pRb activity. In particular, hyperphosphorylation of pRb has been associated with pathological states such as cancer, and therefore, assessing pRb's phosphorylation status is increasingly gaining diagnostic and prognostic value, may be used to inform therapeutic decisions, and is also an important tool for the cancer biologists seeking an understanding of the molecular etiology of cancer. In this chapter, we discuss an immunoblot protocol to detect pRb phosphorylation in two residues, serine 612 and threonine 821, in protein extracts from cancer cells. PMID- 29468545 TI - Immunohistochemical Detection of Retinoblastoma Protein Phosphorylation in Human Tumor Samples. AB - The retinoblastoma protein (pRb) is an important tumor suppressor and cell cycle repressor. pRb is a phosphoprotein whose function is regulated primarily at the level of phosphorylation, and therefore, detecting pRb's phosphorylation status in human tissue samples can be clinically informative. Unfortunately, detection of phosphorylated pRb residues can be technically challenging, as these residues can often be weak antigens. In this chapter, we describe an enhanced sensitivity immunohistochemistry protocol for the staining of phosphorylated serine 249 in pRb, in human lung tumor samples. PMID- 29468544 TI - Immunohistochemical Detection of the Retinoblastoma Protein. AB - The retinoblastoma protein (pRB) plays a key role in proliferative control and genome stability. For these reasons its functions are considered to be tumor suppressive. Its functional status offers critical insight into proliferative control signaling in tissues and in developing malignancies. In this chapter, we outline basic procedures to detect the retinoblastoma protein in formalin fixed, paraffin embedded tissue sections. In addition, we provide protocols to detect phosphorylation levels of pRB in tissues and offer controls to ensure fidelity of measurement. Importantly, these staining methods utilize broadly available reagents and equipment making them accessible to most biomedical research laboratories. PMID- 29468546 TI - Detection of CCND1 Locus Amplification by Fluorescence In Situ Hybridization. AB - It is well known that chromosomal aberrations of tumors are associated with the initiation and progression of malignancy. Fluorescence in situ hybridization (FISH) is a powerful, rapid method to detect chromosome copy number and structural alterations in tissue sections, chromosome, or interphase cellular preparations via hybridization of complementary probe sequences. The technique is based on the complementary nature of DNA double strands, which allows fluorescently labeled DNA probes to be used as probes to label the complementary sequences of target cells, chromosomes, and tissues. FISH technique has many applications, including basic gene mapping, used in pathological diagnosis to detect chromosome and gene copy number aberrations, translocations, microdeletions, and duplications. For the recognition of gene amplifications and deletions, locus-specific probes that are collections of one or a few cloned DNA sequences are routinely used. Multiplex-FISH (M-FISH) technique visualizes all chromosomes with different colors using spectrally distinct fluorophores for each chromosome in one experiment to detect numerical and structural alterations of chromosomes obtained from tumor cells. Recently many of the gene-specific probes are commercially available. PMID- 29468547 TI - Detection of CCND1 Gene Copy Number Variations Using Multiplex Ligation-Dependent Probe Amplification and Fluorescence In Situ Hybridization Methods. AB - The CCND1 locus is located in 11q13 and encodes the G1-S regulatory protein, cyclin D1. Cyclin D1 is frequently amplified in various types of cancers, and is an attractive potential therapeutic target. Multiplex ligation-dependent probe amplification (MLPA) is a new, high-resolution method for the detection of amplification of numerous genes including CCND1 in small amounts of DNA fragments derived from formalin-fixed, paraffin-embedded material in a single reaction. This approach is, however, based on PCR and averages many different cells, so validation by morphological methods such as fluorescence in situ hybridization (FISH) is theoretically mandatory. Here we describe detection of CCND1 gene copy number variations by commercially available MLPA kits and FISH using a bacterial artificial chromosome (BAC) probe. PMID- 29468548 TI - Detection of p16 Promoter Hypermethylation by Methylation-Specific PCR. AB - DNA methylation plays a decisive role in the regulation and control of gene expression. DNA methylation is a covalent modification, in which a methyl group is attached to the 5th carbon of the cytosine ring of a CpG dinucleotide that is located upstream from the promoter region of a gene. Promoter hypermethylation (gain of DNA methylation) of the p16 gene may cause silencing of gene expression and plays an important role in cancer. Therefore, detection of the methylation status of p16 gene is an important tool in epigenetic studies of various human cancers. The methylation-specific PCR (MSP) is the most commonly used technique for studying DNA methylation. This technique is based on bisulfite modification of DNA, which converts unmethylated cytosine (C) into uracil (U) and leaving methylated cytosine (Cm) unchanged. Here we describe the bisulfite modification of DNA samples and detection of promoter methylation of p16 gene from bisulfite treated DNA using MSP. In MSP, modified DNA samples are subjected to PCR amplification using methylated and unmethylated specific primers for the p16 gene separately. The PCR amplified products are then analyzed in a 2.5-3% agarose gel containing ethidium bromide. The PCR amplified band generated by specific sets of primers is used to determine the methylation status of the p16 gene. PMID- 29468549 TI - Immunohistochemical Detection of p16 in Clinical Samples. AB - P16 immunohistochemical expression, a surrogate marker of the retinoblastoma pathway, has become a major adjunct in the routine practice mostly of cervical and head/neck pathology, but with other indications too. In this chapter, a detailed immunohistochemical technique for the detection of p16 is described, followed by indications and interpretation of its expression in uterine, ovarian, vulvar, penile, head-and-neck, melanocytic, and other pathologies. PMID- 29468550 TI - Detection of E2F-DNA Complexes Using Chromatin Immunoprecipitation Assays. AB - Chromatin immunoprecipitation (ChIP), originally developed by John T. Lis and David Gilmour in 1984, has been useful to detect DNA sequences where protein(s) of interest bind. ChIP is comprised of several steps: (1) cross-linking of proteins to target DNA sequences, (2) breaking genomic DNA into 300-1000 bp pieces by sonication or nuclease digestion, (3) immunoprecipitation of protein bound to target DNA with an antibody, (4) reverse cross-linking between target DNA and the bound protein to liberate the DNA fragments, and (5) amplification of target DNA fragment by PCR. Since then, the technology has evolved significantly to allow not only amplifying target sequences by PCR, but also sequencing all DNA fragment bound to a target protein, using a variant of the approach called the ChIP-seq technique (1). Another variation, the ChIP-on-ChIP, allows the detection of protein complexes bound to specific DNA sequences (2). PMID- 29468551 TI - Detection of E2F-Induced Transcriptional Activity Using a Dual Luciferase Reporter Assay. AB - The E2F transcription factors are key targets for the retinoblastoma (RB) tumor suppressor function. The active or inactive status of RB determines the degree by which E2F-dependent gene expression will occur in a given condition. Changes in transcriptional activity in response to extracellular or intracellular stimuli are frequently measured using genetic reporter assays. In particular, dual luciferase reporter assays are most recommended for this purpose because of their improved experimental accuracy. Here we illustrate the usefulness of the dual luciferase reporter assay to detect E2F-mediated transcriptional activity upon overexpression of E2F1 in cultured cells as readout for RB status and function.

AB - Detection of human papilloma virus (HPV) in tissue specimens has been a clinical challenge since last 2 decades; however, screening for presence of E6/E7 transcripts is regarded as the gold standard, and it verifies the active HPV infection. Here, we describe "RNAscope(r) assay" a novel RNA in situ hybridization (ISH) technology; which detects E6/E7 mRNA of seven high risk HPV subtypes (HPV 16, 18, 31, 33, 35, 52, and 58) in formalin fixed paraffin embedded (FFPE) tissue samples. PMID- 29468553 TI - CRISPR/Cas9-Mediated Knockout of Rb1 in Xenopus tropicalis. AB - At this time, no molecular targeted therapies exist for treatment of retinoblastoma. This can be, in part, attributed to the lack of animal models that allow for both rapid identification of novel therapeutic targets and hypothesis driven drug testing. Within this scope, we have recently reported the first genuine genetic nonmammalian retinoblastoma cancer model within the aquatic model organism Xenopus tropicalis (Naert et al., Sci Rep 6: 35263, 2016). Here we describe the methods to generate rb1 mosaic mutant Xenopus tropicalis by employing the CRISPR/Cas9 technology. In depth, we discuss short guide RNA (sgRNA) design parameters, generation, quality control, quantification, and delivery followed by several methods for assessing genome editing efficiencies. As such the reader should be capable, by minor changes to the methods described here, to (co-) target rb1 or any one or multiple gene(s) within the Xenopus tropicalis genome by multiplex CRISPR/Cas9 methodology. PMID- 29468554 TI - SDF 1-alpha Attenuates Myocardial Injury Without Altering the Direct Contribution of Circulating Cells. AB - Stromal cell-derived factor 1-alpha (SDF) is a potent bone marrow chemokine capable of recruiting circulating progenitor populations to injured tissue. SDF has known angiogenic capabilities, but bone marrow-derived cellular contributions to tissue regeneration remain controversial. Bone marrow from DsRed-transgenic donors was transplanted into recipients to lineage-trace circulating cells after myocardial infarction (MI). SDF was delivered post-MI, and hearts were evaluated for recruitment and plasticity of bone marrow-derived populations. SDF treatment improved ventricular function, border zone vessel density, and CD31+ cell frequency post-MI. Bone marrow-derived endothelial cells were observed; these cells arose through both cell fusion and transdifferentiation. Circulating cells also adopted cardiomyocyte fates, but such events were exceedingly rare and almost exclusively resulted from cell fusion. SDF did not significantly alter the proportion of circulating cells that adopted non-hematopoietic fates. Mechanistic insight into the governance of circulating cells is essential to realizing the full potential of cytokine therapies. PMID- 29468555 TI - A model for predicting sulcus-to-sulcus diameter in posterior chamber phakic intraocular lens candidates: correlation between ocular biometric parameters. AB - PURPOSE: The aim of this study was to determine the correlation between ocular biometric parameters and sulcus-to-sulcus (STS) diameter. METHODS: This was a cross-sectional study of preoperative ocular biometry data of patients who were candidates for phakic intraocular lens (IOL) surgery. Subjects underwent ocular biometry analysis, including refraction error evaluation using an autorefractor and Orbscan topography for white-to-white (WTW) corneal diameter and measurement. Pentacam was used to perform WTW corneal diameter and measurements of minimum and maximum keratometry (K). Measurements of STS and angle-to-angle (ATA) were obtained using a 50-MHz B-mode ultrasound device. Anterior optical coherence tomography was performed for anterior chamber depth measurement. Pearson's correlation test and stepwise linear regression analysis were used to find a model to predict STS. RESULTS: Fifty-eight eyes of 58 patients were enrolled. Mean age +/- standard deviation of sample was 28.95 +/- 6.04 years. The Pearson's correlation coefficient between STS with WTW, ATA, mean K was 0.383, 0.492, and - 0.353, respectively, which was statistically significant (all P < 0.001). Using stepwise linear regression analysis, there is a statistically significant association between STS with WTW (P = 0.011) and mean K (P = 0.025). The standardized coefficient was 0.323 and - 0.284 for WTW and mean K, respectively. The stepwise linear regression analysis equation was: (STS = 9.549 + 0.518 WTW - 0.083 mean K). CONCLUSION: Based on our result, given the correlation of STS with WTW and mean K and potential of direct and essay measurement of WTW and mean K, it seems that current IOL sizing protocols could be estimating with WTW and mean K. PMID- 29468556 TI - What Is the Minimum Number of Examined Lymph Nodes After Neoadjuvant Therapy in Rectal Cancer? AB - BACKGROUND: To date, no guidelines have standardized the number of examined lymph nodes (eLNs) after neoadjuvant treatment. This study investigated the minimum number of eLNs required for patients with rectal cancer (RC) who received neoadjuvant treatment. MATERIAL AND METHODS: This study was based on data from the Surveillance, Epidemiology, and End Results (SEER)-Medicare-linked database. We included 2173 patients with RC who received neoadjuvant therapy. Restricted cubic spline was used to analyze the association between eLNs and lymph node metastasis (LNM). RESULTS: The number of eLNs was an independent predictive factor for the presence of LNM (odds ratio 1.033; 95% confidence interval 1.020 1.046; P < 0.001). When the number of eLN <= 16, 10 and 11 eLNs had the highest rates of positive LNM. Analysis of the restricted cubic spline method found that when number of eLNs was < 10, the LNM rate increased rapidly, but this increase was not so obviously when there were > 10 eLNs. CONCLUSIONS: Among RC patients who receive neoadjuvant therapy, the minimum number of eLNs may be 10 to ensure pathological quality. PMID- 29468557 TI - Shear wave elastography in the diagnostics of parathyroid adenomas-new application of the method. AB - PURPOSE: Shear wave elastography (SWE) was described as valuable tool in the diagnostics of distinct types of thyroid lesions, thyroiditis and several other non-thyroidal conditions, such as liver inflammation and fibrosis or diagnostics of breast lesions. The aim of the current study was to assess the appearance of parathyroid adenomas in SWE and to check prospectively if SWE can be valuable additional tool in the diagnostics of pathologically enlarged parathyroids. METHODS: Patients with parathyroid adenomas confirmed by histopathology were included. Subjects with benign thyroid lesions were enrolled to the control group. Elasticity of parathyroid adenomas and benign thyroid nodules was measured and compared. RESULTS: Sixty five patients with parathyroid adenomas and 35 patients with 51 benign thyroid nodules were included. Parathyroid adenomas where significantly more elastic than benign thyroid nodules-mean elasticity of the lesion was 5.2 +/- 7.2 vs. 24.3 +/- 33.8 kPa, respectively. Relative mean elasticity (in comparison with surrounding thyroid tissue) was 0.30 +/- 0.36 and 2.8 +/- 3.9, respectively. CONCLUSIONS: SWE can be useful tool in the diagnostics of parathyroid adenomas. Enlarged parathyroids are significantly more elastic than benign thyroid lesions. Low elasticity of the lesion constitutes feature with high negative prognostic value, allowing for reliable exclusion of suspicion of parathyroid adenomas.

AB - Since clinical experience with biphasic insulin aspart 30 (BIAsp 30) in type 2 diabetes mellitus (T2DM) was reviewed in 2012 after 10 years of use worldwide, additional studies have been published that highlight new aspects, including use in real-world populations. Evidence from 35 new studies confirms and builds upon previous work indicating that BIAsp 30 continues to have pharmacodynamic and clinical advantages over biphasic human insulin (BHI 30), including in real-world practice with unselected populations of patients. BIAsp 30 has also been shown to be safe and efficacious as an add-on to dipeptidyl peptidase-4 (DPP-4) inhibitors. Intensification with BIAsp 30 is a safe and effective way to improve glycemic control, and titration performed by patients can achieve results that are at least comparable to those when being guided by healthcare providers. Stepwise intensification using BIAsp 30 is comparable to intensification using a basal-bolus regimen, and twice-daily BIAsp 30 provides similar glycemic control to a basal-plus regimen. Data from large observational studies, in particular, have identified patient-related characteristics that are associated with improved clinical responses, suggesting that earlier initiation and intensification of therapy is warranted. Finally, new health-economic analyses continue to confirm that BIAsp 30 is cost effective versus other therapies such as BHI 30, neutral protamine Hagedorn (NPH), or insulin glargine in both insulin-naive and insulin experienced patients. After 15 years of clinical use worldwide, analysis of more recent 5-year data indicates that BIAsp 30 remains a safe, effective, and simple to-use insulin for initiation and intensification by diabetes specialists and primary care physicians in a variety of patients with T2DM. PMID- 29468561 TI - Chronic pain in medullary sponge kidney: a rare and never described clinical presentation. AB - Medullary sponge kidney (MSK) is a cause of nephrocalcinosis, associated with hematuria, renal colic, pyelonephritis. There are rare and atypical MSK cases characterized by chronic severe pain (CP), whose features are unknown, in particular the relationship with the stone disease activity. This study analyzes a cohort of MSK-CP patients belonging to three North-America self-support Facebook groups. Patients had to self-administer an on-line questionnaire (on intensity, progression and MSK-associated conditions, stone-related disease, pain features, drug use), the Brief Pain Inventory, the Fatigue Severity Score, and Wisconsin Quality of Life (WQL) in stone formers questionnaires. Ninety-two patients with a diagnosis of MSK joined our survey. Stone rate was very high (3.1 stones per patient-year, < 15% of patients had <= 1 stone per year). Most patients had repeated hospitalizations for stones symptoms (p < 0.001) or pain (p < 0.005). 71% of participants referred a daily pain that interfered strongly with everyday life and quality of life (WQL mean value 29.4). 69% used pain medications daily (70% opioids). In most cases, pain was associated with stone passage, while 15% referred a sine materia pain. We showed how MSK-CP symptoms affect very negatively on the quality of life of these patients. They also have a definite risk of progressing to end-stage kidney disease. Generally, CP seems to be associated with an exceptionally high lithogenic activity, suggesting that a better and earlier metabolic treatment for stone prevention should be the first approach in these patients before mini-invasive treatments to prevent pain. PMID- 29468562 TI - PKCdelta Knockout Mice Are Protected from Dextromethorphan-Induced Serotonergic Behaviors in Mice: Involvements of Downregulation of 5-HT1A Receptor and Upregulation of Nrf2-Dependent GSH Synthesis. AB - We investigated whether a specific serotonin (5-HT) receptor-mediated mechanism was involved in dextromethorphan (DM)-induced serotonergic behaviors. We firstly observed that the activation of 5-HT1A receptor, but not 5-HT2A receptor, contributed to DM-induced serotonergic behaviors in mice. We aimed to determine whether the upregulation of 5-HT1A receptor induced by DM facilitates the specific induction of certain PKC isoform, because previous reports suggested that 5-HT1A receptor activates protein kinase C (PKC). A high dose of DM (80 mg/kg, i.p.) induced a selective induction of PKCdelta out of PKCalpha, PKCbetaI, PKCbetaII, PKCxi, and PKCdelta in the hypothalamus of wild-type (WT) mice. More importantly, 5-HT1A receptor co-immunoprecipitated PKCdelta in the presence of DM. Consistently, rottlerin, a pharmacological inhibitor of PKCdelta, or PKCdelta knockout significantly protected against increases in 5-HT1A receptor gene expression, 5-HT turnover rate, and serotonergic behaviors induced by DM. Treatment with DM resulted in an initial increase in nuclear factor erythroid-2 related factor 2 (Nrf2) nuclear translocation and DNA-binding activity, gamma glutamylcysteine (GCL) mRNA expression, and glutathione (GSH) level. This compensative induction was further potentiated by rottlerin or PKCdelta knockout. However, GCL mRNA and GSH/GSSG levels were decreased 6 and 12 h post-DM. These decreases were attenuated by PKCdelta inhibition. Our results suggest that interaction between 5-HT1A receptor and PKCdelta is critical for inducing DM induced serotonergic behaviors and that inhibition of PKCdelta attenuates the serotonergic behaviors via downregulation of 5-HT1A receptor and upregulation of Nrf2-dependent GSH synthesis. PMID- 29468563 TI - Neurobiological Correlates of Alpha-Tocopherol Antiepileptogenic Effects and MicroRNA Expression Modulation in a Rat Model of Kainate-Induced Seizures. AB - Seizure-triggered maladaptive neural plasticity and neuroinflammation occur during the latent period as a key underlying event in epilepsy chronicization. Previously, we showed that alpha-tocopherol (alpha-T) reduces hippocampal neuroglial activation and neurodegeneration in the rat model of kainic acid (KA) induced status epilepticus (SE). These findings allowed us to postulate an antiepileptogenic potential for alpha-T in hippocampal excitotoxicity, in line with clinical evidence showing that alpha-T improves seizure control in drug resistant patients. To explore neurobiological correlates of the alpha-T antiepileptogenic role, rats were injected with such vitamin during the latent period starting right after KA-induced SE, and the effects on circuitry excitability, neuroinflammation, neuronal death, and microRNA (miRNA) expression were investigated in the hippocampus. Results show that in alpha-T-treated epileptic rats, (1) the number of population spikes elicited by pyramidal neurons, as well as the latency to the onset of epileptiform-like network activity recover to control levels; (2) neuronal death is almost prevented; (3) down-regulation of claudin, a blood-brain barrier protein, is fully reversed; (4) neuroinflammation processes are quenched (as indicated by the decrease of TNF alpha, IL-1beta, GFAP, IBA-1, and increase of IL-6); (5) miR-146a, miR-124, and miR-126 expression is coherently modulated in hippocampus and serum by alpha-T. These findings support the potential of a timely intervention with alpha-T in clinical management of SE to reduce epileptogenesis, thus preventing chronic epilepsy development. In addition, we suggest that the analysis of miRNA levels in serum could provide clinicians with a tool to evaluate disease evolution and the efficacy of alpha-T therapy in SE.

PMID- 29468564 TI - Early Presymptomatic Changes in the Proteome of Mitochondria-Associated Membrane in the APP/PS1 Mouse Model of Alzheimer's Disease. AB - Intracellular beta-amyloid (Abeta) accumulation is an early event in Alzheimer's disease (AD) progression. Recently, it has been uncovered that presenilins (PSs), the key components of the amyloid precursor protein (APP) processing and the beta amyloid producing gamma-secretase complex, are highly enriched in a special sub compartment of the endoplasmic reticulum (ER) functionally connected to mitochondria, called mitochondria-associated ER membrane (MAM). A current hypothesis of pathogenesis of Alzheimer's diseases (AD) suggests that MAM is involved in the initial phase of AD. Since MAM supplies mitochondria with essential proteins, the increasing level of PSs and beta-amyloid could lead to metabolic dysfunction because of the impairment of ER-mitochondrion crosstalk. To reveal the early molecular changes of this subcellular compartment in AD development MAM fraction was isolated from the cerebral cortex of 3 months old APP/PS1 mouse model of AD and age-matched C57BL/6 control mice, then mass spectrometry-based quantitative proteome analysis was performed. The enrichment and purity of MAM preparations were validated with EM, LC-MS/MS and protein enrichment analysis. Label-free LC-MS/MS was used to reveal the differences between the proteome of the transgenic and control mice. We obtained 77 increased and 49 decreased protein level changes in the range of - 6.365 to + 2.988, which have mitochondrial, ER or ribosomal localization according to Gene Ontology database. The highest degree of difference between the two groups was shown by the ATP-binding cassette G1 (Abcg1) which plays a crucial role in cholesterol metabolism and suppresses Abeta accumulation. Most of the other protein changes were associated with increased protein synthesis, endoplasmic-reticulum associated protein degradation (ERAD), oxidative stress response, decreased mitochondrial protein transport and ATP production. The interaction network analysis revealed a strong relationship between the detected MAM protein changes and AD. Moreover, it explored several MAM proteins with hub position suggesting their importance in Abeta induced early MAM dysregulation. Our identified MAM protein changes precede the onset of dementia-like symptoms in the APP/PS1 model, suggesting their importance in the development of AD. PMID- 29468566 TI - Pediatric Psychologists' Collaboration in a National Pediatric Obesity Initiative: A Case Study in Interprofessional Collaboration. AB - Health Care reform calls for collaborative team-based care; psychologists must therefore strengthen their competencies for work in interprofessional clinical care settings. Toward that end, a group of psychologists participated with physicians, dieticians, physical activity specialists, nurses, and others in a national interprofessional workgroup focused on pediatric obesity. The interprofessional group was designed to identify areas in need of national advocacy, key assessment and treatment concerns, and gaps in internal policies and procedures in children's hospitals. This article provides a case report of psychologists' roles and experience in this workgroup, and focuses on factors that underlie successful collaboration among diverse health professionals, as well as potential barriers to success. The participating psychologists developed a working model for collaboration with other disciplines. Additionally, they formed a Psychology Subcommittee to identify and address discipline-specific issues regarding collaborative practice in pediatric psychology. Lessons learned in this interprofessional collaborative undertaking have relevance for future collaborative endeavors. PMID- 29468567 TI - The Role of Optimism, Social Constraints, Coping, and Cognitive Processing in Psychosocial Adjustment Among Breast Cancer Survivors. AB - The social-cognitive processing model suggests that a socially constrained environment may impede adjustment to a chronic illness. The present study primarily investigated the mediating psychological pathways through which social constraints on cancer-related disclosure, low optimism, disengagement-oriented coping, and brooding could be associated with low levels of psychosocial adjustment. One hundred twenty-five female breast cancer survivors participated in a cross-sectional study. Path analysis was used to examine the proposed model. Low optimism, increased social constraints, and higher levels of brooding appeared to be risk factors for poor psychosocial adjustment to breast cancer. Disengagement-oriented coping and brooding partially mediated the relationship between social constraints and adjustment. Brooding totally mediated the relationship between disengagement-oriented coping and adjustment. The current findings provide support for the value of the social-cognitive processing model among breast cancer survivors. The mapping of psychological pathways of adjustment to breast cancer may have useful clinical implications for better adjustment outcomes. PMID- 29468568 TI - Cognitive Behavior Therapy for Fear of Cancer Recurrence: A Case Study. AB - This case study describes the course and content of cognitive behavior therapy (CBT) for clinical fear of cancer recurrence (FCR) in a breast cancer survivor. The CBT for clinical FCR consisted of seven face-to-face therapy sessions and one telephone session. The primary treatment goal was to reduce FCR severity by modifying cognitive processes and dysfunctional behavior. Assessments of FCR and quality of life were completed by the breast cancer survivor pre-therapy, post therapy, and at 6 and 12 months of post-therapy. In each treatment session, perceived control over FCR was assessed. A clinical nurse specialist participated in evaluation interviews. The patient's perceived control over FCR increased during the therapy, and FCR severity declined to a non-clinical level. This improvement was still evident at the 6- and 12-month follow-up assessments and was supported by results for secondary and exploratory outcomes measures. FCR offers a great challenge for health care professionals due to the lack of effective treatment options. This case study shows how clinical FCR can be addressed with CBT and can contribute to the improvement of care for cancer survivors. PMID- 29468569 TI - Illness Identity in Adults with a Chronic Illness. AB - The present study examines the concept of illness identity, the degree to which a chronic illness is integrated into one's identity, in adults with a chronic illness by validating a new self-report questionnaire, the Illness Identity Questionnaire (IIQ). Self-report questionnaires on illness identity, psychological, and physical functioning were assessed in two samples: adults with congenital heart disease (22-78 year old; n = 276) and with multisystem connective tissue disorders (systemic lupus erythematosus or systemic sclerosis; 17-81 year old; n = 241). The IIQ could differentiate four illness identity states (i.e., engulfment, rejection, acceptance, and enrichment) in both samples, based on exploratory and confirmatory factor analysis. All four subscales proved to be reliable. Rejection and engulfment were related to maladaptive psychological and physical functioning, whereas acceptance and enrichment were related to adaptive psychological and physical functioning. The present findings underscore the importance of the concept of illness identity. The IIQ, a self report questionnaire, is introduced to measure four different illness identity states in adults with a chronic illness. PMID- 29468570 TI - Quality Improvement in Health Care: The Role of Psychologists and Psychology. AB - Quality Improvement (QI) is a health care interprofessional team activity wherein psychology as a field and individual psychologists in health care settings can and should adopt a more robust presence. The current article makes the argument for why psychology's participation in QI is good for health care, is good for our profession, and is the right thing to do for the patients and families we serve. It reviews the varied ways individual psychologists and our profession can integrate quality processes and improve health care through: (1) our approach to our daily work; (2) our roles on health care teams and involvement in organizational initiatives; (3) opportunities for teaching and scholarship; and (4) system redesign and advocacy within our health care organizations and health care environment. PMID- 29468571 TI - Leadership Perspectives on Integrating Psychologists into Specialty Care Clinics: An Evolving Paradigm. AB - Integration of health psychologists into specialty care is a shift in the tertiary care construct that addresses all aspects of a patient's presentation, including psychiatric/social history, psychological well-being, and behavioral contributions to the disease process, assuring both optimal health outcomes and cost-effectiveness in a financially challenging healthcare environment. In this paper, we discuss leadership perspectives (physician and psychologists) on the factors involved in integrating a health psychologist into a busy tertiary care environment. Ultimately, we hope that this information provides a primer on how to frame a proposal for an integrated health psychologist emphasizing the elements important to senior medical leadership and administration. First, we briefly discuss the current payer framework, providing support for integration emphasizing costs and other metrics. Second, we introduce organizational structure models and strategies for integration. Lastly, we will discuss the unique skillset psychologists possess, and additional skills necessary, to be effective in the changing landscape of healthcare. We think this information is important both for leaders attempting to integrate a health psychologist into specialty care and for the early career health psychologist embarking on his/her first senior staff position.

PMID- 29468573 TI - Relationship Between Odor Identification and Visual Distractors in Children with Autism Spectrum Disorders. AB - Understanding the nature of olfactory abnormalities is crucial for optimal interventions in children with autism spectrum disorders (ASD). However, previous studies that have investigated odor identification in children with ASD have produced inconsistent results. The ability to correctly identify an odor relies heavily on visual inputs in the general population. We tested odor identification in eight children with ASD and eight age-matched children with typical development (TD). After confirming that all children were able to identify each odor without visual input, we measured odor identification under the visual distractor condition. Odor identification was hindered by visual distractors for all children with ASD but was not affected in all children with TD. Our results improve understanding of odor identification in ASD. PMID- 29468574 TI - Superior Disembedding in Children with ASD: New Tests Using Abstract, Meaningful, and 3D Contexts. AB - Since its initial development, the embedded figures test (EFT) has been used extensively to measure local-global perceptual style. However, little is known about the perceptual factors that influence target detection. The current study aimed to investigate disembedding in children with and without ASD, aged 8-15 years, using the newly developed, stimulus-controlled L-EFT, M-EFT and D-EFT. Firstly, results revealed superior disembedding for children with ASD, irrespective of the type of target or embedding context, although the ASD group took more time in both the M-EFT and D-EFT. Secondly, the number of target lines continuing into the context proved more of a hindrance for the controls. Taken together, these findings provide strong evidence to support the notion of superior disembedding in ASD. PMID- 29468575 TI - Autism Spectrum Traits Linked with Reduced Performance on Self-Report Behavioural Measures of Cognitive Flexibility. AB - Deficits in cognitive flexibility are thought to underpin the core symptom of repetitive and restricted patterns of behaviour in autism spectrum disorder (ASD). Studies investigating this relationship, however, report inconsistent results. This is partly due to the variable nature of measures used to assess the construct of flexibility. The main purpose of this study was to investigate whether ASD traits differentially predict cognitive flexibility performance on lab-based neurocognitive measures relative to behavioural self-reports in a non clinical sample of young adults. Our results indicate that ASD traits exclusively predict performance on behavioural self-reports of cognitive flexibility. These findings highlight the possibility that behavioural self-reports are a better index than lab-based neurocognitive measures to capture cognitive flexibility impairments in individuals with ASD.

PMID- 29468576 TI - Evaluating Sex and Age Differences in ADI-R and ADOS Scores in a Large European Multi-site Sample of Individuals with Autism Spectrum Disorder. AB - Research on sex-related differences in Autism Spectrum Disorder (ASD) has been impeded by small samples. We pooled 28 datasets from 18 sites across nine European countries to examine sex differences in the ASD phenotype on the ADI-R (376 females, 1763 males) and ADOS (233 females, 1187 males). On the ADI-R, early childhood restricted and repetitive behaviours were lower in females than males, alongside comparable levels of social interaction and communication difficulties in females and males. Current ADI-R and ADOS scores showed no sex differences for ASD severity. There were lower socio-communicative symptoms in older compared to younger individuals. This large European ASD sample adds to the literature on sex and age variations of ASD symptomatology. PMID- 29468577 TI - Allergy-preventive effects of linarinic acid and its tetrahydropyrrolo[2,1 b]quinazoline derivatives isolated from Linaria vulgaris. AB - Linarinic acid, (-)-1,2,3,9-tetrahydropyrrolo[2,1-b]quinazoline-1-carboxylic acid (4a), was isolated from the ethanol extract of Linaria vulgaris Mill. In our previous study, a series of tetrahydropyrrolo[2,1-b]quinazoline derivatives 4b, 4c, 5a, 5b, 6a and 6b that were structurally related to 4a and evaluated as neuroprotective agents were synthesized. The aim of the present study was to investigate the novel features of these compounds. We examined their allergy preventive effects using an in vivo assay system we developed previously, that monitors a decrease in blood flow in the tail vein of mice subjected to sensitization with hen egg-white lysozyme. We observed that 4a and its three derivatives, amide (6a), ester (5a), bromine (4b), and alcohol substituent (6b), showed significant allergy-preventive activities. The study confirmed the allergy preventive activity of tetrahydropyrrolo[2,1-b]quinazoline derivatives by comprehensively monitoring the specific blood flow decrease occurring in the induction phase of allergy. This finding may aid in the development of new agents for the treatment of allergic diseases such as atopic dermatitis, allergic asthma, and hay fever. PMID- 29468579 TI - Mouse Injury Model of Polytrauma and Shock. AB - Severe injury and shock remain major sources of morbidity and mortality worldwide. Immunologic dysregulation following trauma contributes to these poor outcomes. Few, if any, therapeutic interventions have benefited these patients, and this is due to our limited understanding of the host response to injury and shock. The Food and Drug Administration requires preclinical animal studies prior to any interventional trials in humans; thus, animal models of injury and shock will remain the mainstay for trauma research. However, adequate animal models that reflect the severe response to trauma in both the acute and subacute phases have been limited. Here we describe a novel murine model of polytrauma and shock that combines hemorrhagic shock, cecectomy, long bone fracture, and soft-tissue damage. This model produces an equivalent Injury Severity Score associated with adverse outcomes in humans, and may better recapitulate the human leukocyte, cytokine, transcriptomic, and overall inflammatory response following injury and hemorrhagic shock. PMID- 29468580 TI - Measurement of Intracranial Pressure in Freely Moving Rats. AB - Brain injury, such as from stroke and trauma, can be complicated by elevated intracranial pressure (ICP). Although raised ICP can be a significant determinant of morbidity and mortality, clinical studies often report widely varying ICP measurements depending on location of measurement and technique used. For the same reasons, reported ICP measurements also vary widely in animal models. The need for anesthesia or tethered connections with some methods of ICP measurement in animals may introduce additional confounds. Moreover, these methods are not well suited for prolonged, continuous measurement. Here, we describe an approach to continually measure ICP in awake, freely moving rats for several days. This technique uses a commercially available, wireless pressure sensor mounted on the head to measure ICP from the epidural space via a fluid-filled catheter. We have demonstrated that this approach reliably detects elevations in ICP that last for several days after ischemic and hemorrhagic strokes in rat. PMID- 29468581 TI - A Lateral Fluid Percussion Injury Model for Studying Traumatic Brain Injury in Rats. AB - Traumatic brain injury (TBI) diagnoses have increased in frequency during the past decade, becoming a silent epidemic. The pathophysiology of TBI involves pathophysiological processes affecting the brain, induced by traumatic biomechanical forces resulting in temporary impairment of neurological function. Preclinical models have been generated to recapitulate the mechanical, neuroinflammatory, and behavioral outcomes observed in the clinical setting. The lateral fluid percussion (LFP) model is the most extensively used and well characterized model of nonpenetrating and nonischemic TBI. The model is reproducible and can be adjusted to produce a mild to moderate and severe injury, as reflected by mortality and return of reflexes, by adjusting the amount of force applied. The histopathological changes achieved with this model reproduce that seen in human TBI including focal contusion in the cortex, with accompanying intraparenchymal punctate hemorrhage, followed by inflammation and neuronal degeneration. This chapter describes the LFP model, which produces a mixed model of focal and diffuse brain injury that progresses over time affecting predominantly the cortical parenchyma. PMID- 29468582 TI - A Mouse Controlled Cortical Impact Model of Traumatic Brain Injury for Studying Blood-Brain Barrier Dysfunctions. AB - Traumatic brain injury (TBI) is one of the leading causes of death and disability worldwide. It is a silently growing epidemic with multifaceted pathogenesis, and current standards of treatments aim to target only the symptoms of the primary injury, while there is a tremendous need to explore interventions that can halt the progression of the secondary injuries. The use of a reliable animal model to study and understand the various aspects the pathobiology of TBI is extremely important in therapeutic drug development against TBI-associated complications. The controlled cortical impact (CCI) model of TBI described here, uses a mechanical impactor to inflict a mechanical injury into the mouse brain. This method is a reliable and reproducible approach to inflict mild, moderate or severe injuries to the animal for studying TBI-associated blood-brain barrier (BBB) dysfunctions, neuronal injuries, brain edema, neurobehavioral changes, etc. The present method describes how the CCI model could be utilized for determining the BBB dysfunction and hyperpermeability associated with TBI. Blood-brain barrier disruption is a hallmark feature of the secondary injury that occur following TBI, frequently associated with leakage of fluid and proteins into the extravascular space leading to vasogenic edema and elevation of intracranial pressure. The method described here focuses on the development of a CCI-based mouse model of TBI followed by the evaluation of BBB integrity and permeability by intravital microscopy as well as Evans Blue extravasation assay. PMID- 29468583 TI - A Rat Model of Hemorrhagic Shock for Studying Vascular Hyperpermeability. AB - Vascular hyperpermeability is one of the known detrimental effects of hemorrhagic shock, which we continually try to understand, minimize, and reverse. Here, we describe induction of hemorrhagic shock in a rat and studying of its effects on vascular permeability, using intravital microscopy. In this protocol, hemorrhagic shock will be induced by withdrawing blood to reduce the mean arterial pressure (MAP) to 40 mmHg for 60 min followed by resuscitation for 60 min. To study the changes in vascular permeability following hemorrhagic shock, the rats will be given FITC-albumin, a fluorescent tracer, intravenously. Following this, the FITC albumin flux across the vessel will be measured in mesenteric postcapillary venules by determining fluorescent intensity intravascularly and extravascularly under intravital microscopy. PMID- 29468584 TI - Assessment of Cardiovascular Function and Microvascular Permeability in a Conscious Rat Model of Alcohol Intoxication Combined with Hemorrhagic Shock and Resuscitation. AB - Hypotension, cardiac depression, and elevated microvascular permeability are known problems that complicate resuscitation of patients following traumatic injury, particularly those who are also intoxicated from alcohol consumption. A conscious rat model of combined alcohol intoxication and hemorrhagic shock has been used to study the hemodynamic mechanisms involved. Here, we describe using this model to study microvascular leakage and cardiac electrical activity. PMID- 29468585 TI - Intracerebral Hemorrhage in Mice. AB - Intracerebral hemorrhage is the most devastating stroke subtype with high rates of mortality and morbidity. Furthermore, no clinically approved treatment exists that effectively increases survival or improves quality of life for survivors. Effective modeling is necessary to elucidate the pathophysiological mechanisms of intracerebral hemorrhage and evaluate potential therapeutic approaches. Rodent models are most utilized because of their cost-effectiveness, and because rodent brain development and structures are well documented. Herein, we describe two intracerebral hemorrhage mouse models: the autologous blood double-injection and collagenase infusion models. PMID- 29468586 TI - A Rat Burn Injury Model for Studying Changes in Microvascular Permeability. AB - The management of burn patients is an extremely complex and clinically challenging for patient care. Aside from the increasing reports of burn injury and morbidity and mortality directly related to it, the pathobiology of burn trauma is not clearly understood. The rat model of burn trauma described here is currently used in research laboratories to study various aspects of burn injury, including vascular dysfunctions. This model demonstrates the infliction of thermal injury in Sprague-Dawley rats using a well-established boiled water approach. We have utilized intravital microscopy to examine the microvascular hyperpermeability, the excessive leakage of proteins and fluids from the intravascular space to the extravascular space in mesenteric postcapillary venules using this model. An increase in microvascular permeability is a strong indicator of microvascular dysfunctions leading to tissue edema in burn trauma.

AB - The middle cerebral artery occlusion (MCAO) model is widely used for inducing a focal cerebral ischemic insult (stroke) in rodents. Here, we describe a method for transient MCAO technique without craniotomy in both mice and rats. In our laboratory, this technique yields consistent secondary brain damage that evolves over a period of 3-7 days of reperfusion after transient MCAO. We also describe the methods for analyzing postischemic motor dysfunction and infarct volume in rodents subjected to transient MCAO. PMID- 29468588 TI - A Complete Guide to Using the Endothelin-1 Model of Stroke in Conscious Rats for Acute and Long-Term Recovery Studies. AB - Multiple methods exist to model permanent and transient ischemia under anesthesia in animals, however most human strokes occur while conscious. The use of endothelin-1 as a vasoconstrictor applied to the perivascular surface of the middle cerebral artery is one of the only methods for inducing stroke in conscious animals. Here, we describe standard operating procedures for stereotaxic placement of an ET-1 guide probe above the middle cerebral artery, induction of stroke in conscious rats, predictive outcome scoring during stroke, and neurological behavioral tests that we use to monitor transient and continuing deficits. The inclusion of long term neurological assessment is of particular importance when taking into consideration the effects of stroke on brain remodeling. PMID- 29468589 TI - A Murine Model of Hind Limb Ischemia to Study Angiogenesis and Arteriogenesis. AB - Therapeutic angiogenesis offers promise as a novel treatment that is complementary to surgical or endovascular procedures for peripheral arterial diseases (PAD). Appropriate development and use of hind limb ischemia models is necessary for successful studies of therapeutic angiogenesis and/or arteriogenesis. In this chapter, we describe two commonly used murine unilateral hind limb ischemia models, the femoral artery transection model and the femoral/saphenous artery excision model. PMID- 29468590 TI - A Murine Model of Myocardial Ischemia-Reperfusion Injury. AB - Ligation of the left anterior descending (LAD) coronary artery in the mouse heart is a widely used model to simulate myocardial infarction and ischemia-reperfusion injury. Here we describe a ligation technique routinely performed in our laboratory to induce myocardial infarction that may be used to study ischemia reperfusion injury in the myocardium. The methods described enhance location of the LAD coronary artery to allow for accurate ligation, thus increasing reproducibility of infarct size and location. PMID- 29468591 TI - A Rat Model of Perinatal Seizures Provoked by Global Hypoxia. AB - Hypoxic-ischemic encephalopathy (HIE) refers to acute brain injury that results from perinatal asphyxia. HIE is a major cause of neonatal seizures, and outcomes can range from apparent recovery to severe cognitive impairment, cerebral palsy, and epilepsy. Acute partial seizures frequently aid in indicating the severity and localization of brain injury. However, evidence also suggests that the occurrence of seizures further increases the likelihood of epilepsy in later life regardless of the severity of the initial injury. Here, we describe a neonatal rat model of seizure-provoking mild hypoxia without overt brain injury that has been used to investigate potential epileptogenic effects of hypoxia-associated seizures alone on neonatal brain development. Clinically, HIE is defined by brain injury, and thus, this model is not intended to mimic clinical HIE. Rather, its utility is in providing a model to understand the dynamic and long-term regulation of brain function and how this can be perturbed by early life seizures that are provoked by a commonly encountered pathophysiological trigger. Additionally, the model allows the study of brain pathophysiology without the potential confound of variable neuroanatomical changes that are reactive to widespread cell death. PMID- 29468592 TI - Experimental Protocol for Cecal Ligation and Puncture Model of Polymicrobial Sepsis and Assessment of Vascular Functions in Mice. AB - Sepsis is the systemic inflammatory response syndrome that occurs during infection and is exacerbated by the inappropriate immune response encountered by the affected individual. Despite extensive research, sepsis in humans is one of the biggest challenges for clinicians. The high mortality rate in sepsis is primarily due to hypoperfusion-induced multiorgan dysfunctions , resulting from a marked decrease in peripheral resistance. Vascular dysfunctions are further aggravated by sepsis-induced impairment in myocardial contractility. Circulatory failure in sepsis is characterized by refractory hypotension and vascular hyporeactivity (vasoplegia) to clinically used vasoconstrictors. To investigate the complex pathophysiology of sepsis and its associated multiple organ dysfunction, several animal models have been developed. However, cecal ligation and puncture (CLP) model of murine sepsis is still considered as 'gold standard' in sepsis research. In this protocol we have described the standard surgical procedure to induce polymicrobial sepsis by cecal ligation and puncture. Further, we have described the protocol to study the molecular mechanisms underlying vascular dysfunctions in sepsis. PMID- 29468593 TI - Methods to Study the Innate Immune Response to Sepsis. AB - This chapter describes techniques to measure the innate immune response in the mouse cecal ligation and puncture model of sepsis. The reader will learn how to perform retro-orbital bleeds to harvest serum from mice and learn how to perform peritoneal lavage to harvest cells and inflammatory mediators from this compartment. The enzyme-linked immunosorbent assay (ELISA) technique is described as a method to measure the levels of cytokines and chemokines in these fluids. Additionally, this chapter describes techniques to stain the cellular fraction of the peritoneal lavage with fluorescently labeled antibodies, and perform fluorescence activated cell sorting (FACS) to quantify macrophages and neutrophils in this compartment. PMID- 29468594 TI - An Ovine Model for Studying the Pathophysiology of Septic Acute Kidney Injury. AB - The development of acute kidney injury (AKI) is both a significant and independent prognostic factor of mortality in patients with sepsis, but its pathophysiology remains unclear. Herein, we describe an ovine model of sepsis evoked by the administration of live Escherichia coli in which there is hypotension, peripheral vasodilatation with a large increase in cardiac output; a similar hyperdynamic state to that commonly reported in humans. Interestingly, in this sheep model of sepsis, despite an increase in global kidney blood flow, there is a progressive reduction in renal function. Although renal hyperperfusion develops, renal tissue hypoxia due to redistribution of intrarenal blood flow may contribute to the pathogenesis of septic AKI. We have, therefore, developed a novel methodology to chronically implant combination probes to monitor intrarenal tissue perfusion and oxygen tension during the development of septic AKI in conscious sheep with hyperdynamic sepsis. PMID- 29468595 TI - An In Vitro Model of Traumatic Brain Injury. AB - Traumatic brain injury (TBI) is a significant problem causing high mortality globally. Methods to increase possibilities for treatment and prevention of secondary injuries resulting from the initial physical insult are thus much needed. TBI affects the central nervous system (CNS) and the neurovascular unit as a whole in numerous ways but one of the primarily compromised components is the blood-brain barrier (BBB).In this chapter, we present a detailed procedure on how stretch injury and oxygen-glucose deprivation (OGD) are applied to brain microvascular endothelial cells of the BBB in order to replicate the actual impact they receive during TBI. PMID- 29468596 TI - An In Vitro Oxygen-Glucose Deprivation Model for Studying Ischemia-Reperfusion Injury of Neuronal Cells. AB - Ischemia-reperfusion syndromes of the heart and brain are the leading cause of death and long-term disability worldwide. Development of effective treatments for myocardial infarction, stroke, cardiac arrest and their sequelae requires preclinical models that replicate specific features of ischemia-reperfusion. The complexities of intact animals, including the integrated function of organ systems, autonomic innervation and endocrine factors, often preclude detailed study of specific components of ischemia-reperfusion injury cascades. Ischemia represents the interruption of metabolic fuel and oxygen delivery to support cellular oxidative metabolism; reintroduction of oxygen upon reperfusion of ischemic tissue triggers oxidative stress which initiates the reperfusion injury cascade culminating in injury and death of cells and tissues. Thus, cultured cells subjected to hypoxia, fuel deprivation and reoxygenation replicate the cardinal features of ischemia-reperfusion, while accommodating interventions such as siRNA suppression of specific genes and pharmacological activation or inhibition of signaling cascades that are not feasible in more complex preparations, especially intact animals. This chapter describes an in vitro OGD reoxygenation cell culture model, an excellent preparation to examine the cellular mechanisms mediating ischemia-reperfusion injury and/or cytoprotection. PMID- 29468597 TI - Measurement of Microvascular Endothelial Barrier Dysfunction and Hyperpermeability In Vitro. AB - Loss of microvascular endothelial barrier integrity leads to vascular hyperpermeability and vasogenic edema in a variety of disease processes including trauma, ischemia and sepsis. Understanding these principles gives valuable information on pathophysiology and therapeutic drug development. While animal models of traumatic and ischemic injuries are useful to understand vascular dysfunctions associated with such injuries, in vitro barrier integrity assays are reliable and helpful adjuncts to understand the cellular and molecular changes and signaling mechanisms that regulate barrier function. We describe here the endothelial monolayer permeability assay and transendothelial electrical resistance (TEER) measurement as in vitro methods to test changes in microvascular integrity and permeability. These in vitro assays are based on either the measurement of electrical resistance of the monolayer or the quantitative evaluation of fluorescently tagged molecules (e.g., FITC-dextran) that pass through the monolayer when there is damage or breakdown. PMID- 29468598 TI - Microbiological analysis and the outcomes of periodontal treatment with or without adjunctive systemic antibiotics-a retrospective study. AB - OBJECTIVES: The purpose of this retrospective study was to assess the impact of microbiological diagnostics on the outcomes of periodontal treatment with or without adjunctive use of systemic antibiotics. MATERIALS AND METHODS: Patient files were screened for microbiological analysis before (T1) and after non surgical periodontal therapy (T2). Medical history, diagnosis, clinical data, and results of the microbiological analysis were extracted from the patient's file. After descriptive statistics, logistic regression analysis was performed to model the presence of 90 and 50% reductions of numbers of sites with probing depths (PD) of >= 5 mm at T2 (90%-PD5 and 50%-PD5), respectively, against the presence of bacterial species, clinical diagnosis, and adjunctive use of systemic antibiotics. RESULTS: Eighteen patients diagnosed with aggressive periodontitis (AP, 17 with adjunctive antibiotics) and 84 with chronic periodontitis (CP, 31 with adjunctive antibiotics) were included in the analysis. Logistic modeling of bacteria at T1 to 90%-PD5 failed to show any statistical significance. Using 50% PD5, presence of all Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola and in particular of T. denticola at T1 was associated with good response to therapy. Modeling of bacterial presence to 90-%PD5 and to 50 %PD5 at T2 found an association with absence of T. forsythia (90-%PD5 and 50 %PD5) and of T. denticola and Campylobacter rectus (50%-PD5). Modeling bacteria at T1, antibiotic group and oral hygiene at T2 on 50%-PD5 revealed odds ratio (OR) of the adjunctive antibiotic group between 2.70 and 52.4, of the oral hygiene between 3.27 and 4.11, and of the bacteria at T1 up to 28.6 (Porphyromonas gingivalis, T. forsythia, or T. denticola). CONCLUSION: Microbiological analysis of the most important species associated with periodontal diseases appears to support a clinically based decision for the adjunctive use of systemic antibiotics. CLINICAL RELEVANCE: The present findings appear to support the use microbiological testing to strengthen the clinical decision making process for either using or not using systemic antibiotics in conjunction with non-surgical periodontal therapy. PMID- 29468599 TI - Determination of nicotine content in teeth submitted to prophylaxis and in-office bleaching by gas chromatography-mass spectrometry (GC-MS). AB - OBJECTIVES: The objective of this study was to evaluate the dental color exposed to acute cigarette smoke treatment and quantify the amount of nicotine in samples exposed to cigarette smoke, after dental prophylaxis and after in-office bleaching. MATERIALS AND METHODS: Sixty-nine healthy human molars were subjected to cigarette smoke in a cigarette machine. The teeth were divided into three groups: positive control, prophylaxis, and bleaching. Forty cycles of smoke exposition with duration of 15 min each were performed using 10 cigarettes (positive control). Dental prophylaxis was performed with a rotating brush and prophylaxis paste; in-office bleaching was performed with 35% hydrogen peroxide, in two sessions of three 15-min applications, with a 1-week interval between sessions. The color was evaluated at the baseline, after exposure to cigarette smoke, after dental prophylaxis, and after in-office bleaching. Teeth from each group were powdered and analyzed by gas chromatography-mass spectrometry in order to measure the amount of nicotine present in each group. Data from quantification of nicotine and color change were analyzed by one-way ANOVA and Tukey's test (alpha = 0.05). Data for subjective and objective color evaluation, a perceptible dental darkening occurred in teeth after exposure to cigarette smoke. Dental prophylaxis was able to recover the original color of teeth however, only after bleaching teeth became whiter than at the baseline (p < 0.001). The amount of nicotine was significantly different and higher in positive control group (3.3 +/ 1.3 MUg/g of tooth), followed by the prophylaxis group (2.1 +/- 1.4 MUg/g) and the bleaching group (0.8 +/- 0.3 MUg/g) (p < 0.001). CONCLUSIONS: Cigarette smoke penetrates into the dental structure. Dental prophylaxis and bleaching with 35% hydrogen peroxide can partially remove the nicotine from tobacco smoke. However, when in-office bleaching was applied, a more significant nicotine removal was achieved. CLINICAL SIGNIFICANCE: Dental prophylaxis could remove most of the external nicotine-staining on the tooth surfaces while bleaching could further reduce the external and internal nicotine-staining of teeth. PMID- 29468600 TI - CAD/CAM produces dentures with improved fit. AB - OBJECTIVES: Resin polymerisation shrinkage reduces the congruence of the denture base with denture-bearing tissues and thereby decreases the retention of conventionally fabricated dentures. CAD/CAM denture manufacturing is a subtractive process, and polymerisation shrinkage is not an issue anymore. Therefore, CAD/CAM dentures are assumed to show a higher denture base congruence than conventionally fabricated dentures. It has been the aim of this study to test this hypothesis. MATERIALS AND METHODS: CAD/CAM dentures provided by four different manufacturers (AvaDent, Merz Dental, Whole You, Wieland/Ivoclar) were generated from ten different master casts. Ten conventional dentures (pack and press, long-term heat polymerisation) made from the same master casts served as control group. The master casts and all denture bases were scanned and matched digitally. The absolute incongruences were measured using a 2-mm mesh. RESULTS: Conventionally fabricated dentures showed a mean deviation of 0.105 mm, SD = 0.019 from the master cast. All CAD/CAM dentures showed lower mean incongruences. From all CAD/CAM dentures, AvaDent Digital Dentures showed the highest congruence with the master cast surface with a mean deviation of 0.058 mm, SD = 0.005. Wieland Digital Dentures showed a mean deviation of 0.068 mm, SD = 0.005, Whole You Nexteeth prostheses showed a mean deviation of 0.074 mm, SD = 0.011 and Baltic Denture System prostheses showed a mean deviation of 0.086 mm, SD = 0.012. CONCLUSIONS: CAD/CAM produces dentures with better fit than conventional dentures. CLINICAL RELEVANCE: The present study explains the clinically observed enhanced retention and lower traumatic ulcer-frequency in CAD/CAM dentures. PMID- 29468601 TI - Patient and Clinician Perspectives on Shared Decision-making in Early Adopting Lung Cancer Screening Programs: a Qualitative Study. AB - BACKGROUND: Guidelines recommend, and Medicare requires, shared decision-making between patients and clinicians before referring individuals at high risk of lung cancer for chest CT screening. However, little is known about the extent to which shared decision-making about lung cancer screening is achieved in real-world settings. OBJECTIVE: To characterize patient and clinician impressions of early experiences with communication and decision-making about lung cancer screening and perceived barriers to achieving shared decision-making. DESIGN: Qualitative study entailing semi-structured interviews and focus groups. PARTICIPANTS: We enrolled 36 clinicians who refer patients for lung cancer screening and 49 patients who had undergone lung cancer screening in the prior year. Participants were recruited from lung cancer screening programs at four hospitals (three Veterans Health Administration, one urban safety net). APPROACH: Using content analysis, we analyzed transcripts to characterize communication and decision making about lung cancer screening. Our analysis focused on the recommended components of shared decision-making (information sharing, deliberation, and decision aid use) and barriers to achieving shared decision-making. KEY RESULTS: Clinicians varied in the information shared with patients, and did not consistently incorporate decision aids. Clinicians believed they explained the rationale and gave some (often purposely limited) information about the trade offs of lung cancer screening. By contrast, some patients reported receiving little information about screening or its trade-offs and did not realize the CT was intended as a screening test for lung cancer. Clinicians and patients alike did not perceive that significant deliberation typically occurred. Clinicians perceived insufficient time, competing priorities, difficulty accessing decision aids, limited patient comprehension, and anticipated patient emotions as barriers to realizing shared decision-making. CONCLUSIONS: Due to multiple perceived barriers, patient-clinician conversations about lung cancer screening may fall short of guideline-recommended shared decision-making supported by a decision aid. Consequently, patients may be left uncertain about lung cancer screening's rationale, trade-offs, and process.

In striving to enhance quantitative signal detection capability further, other data streams are being considered for their potential contribution as sources of emerging signals, one of which is longitudinal observational databases, including electronic medical record (EMR) and transactional insurance claims databases. Quantitative signal detection on such databases is a nascent field-with published methods being primarily based either on individual metrics, which may not effectively represent the complexity of the longitudinal records and their necessary variation for analysis for drug outcome pairs, or on visualization discovery approaches leveraging multiple aspects of the records, which are not particularly tractable to high-throughput hypothesis-free signal detection. One extensively tested example of the latter is chronographs. METHODS: We apply a disturbance detection algorithm to chronographs using UK EMR The Health Improvement Network (THIN) data. The algorithm utilizes autoregressive integrated moving average (ARIMA)-based time series methodology designed to find disturbances that occur outside the normal pattern trends of the ARIMA model for the chronograph. Chronographs currently highlight drug-event pairs as potentially worthy of further clinical assessment, via filter-based increases in disproportionality scores from before to after the index drug exposure, tested across a range of case and control windows. RESULTS: We replicate the findings on six exemplar chronographs from a previous publication, and show how disturbances can be effectively detected across this set of pairs. Further, 692 disturbances were detected in analysis of all 384 individual READ code outcomes ever recorded 50 or more times for patients prescribed sibutramine. The disturbances are algorithmically further broken into subsets of clinical interest. CONCLUSION: Overall, the disturbance algorithm approach shows promising capacity for detecting outliers, and shows tractability of the algorithmic approach for large-scale screening. The method offers an array of pattern types for detection and clinical review. PMID- 29468604 TI - Urinary Diversion After Radical Cystectomy for Bladder Cancer: Comparing Trends in the US and Germany from 2006 to 2014. AB - OBJECTIVE: Our aim was to assess and compare trends of urinary diversion (UD) for patients receiving radical cystectomy for the treatment of bladder cancer in the US and Germany, and to investigate decisive predictors for the choice of UD. METHODS: We analyzed the nationwide German hospital billing database and the Nationwide Inpatient Sample (NIS) from 2006 to 2014. Cases with a bladder cancer diagnosis combined with RC were included, and trends in the choice of UD, transfusion rates, length of stay, and mortality were assessed. RESULTS: From 2006 to 2014, the total number of RCs recorded within the NIS were 17,711, with a varying annual caseload of 1666-2009, while RC numbers increased from 5627 to 7390 in Germany (p < 0.001 for trends), with a total of 60,447 cases. The share of incontinent UD in the US remained stable at 93%, while increasing from 63.2 to 70.8% in Germany. Multivariate models indicated age and sex were the most important factors associated with the choice of UD in both countries, while hospital caseload and teaching status were less relevant factors in the US. In hospital mortality was lower in the US compared with Germany (1.9% vs. 4.6%; p < 0.001), with significantly shorter hospital stays (10.7 days in the US vs. 25.1 days in Germany; p < 0.001). CONCLUSIONS: The increasing age of patients with presumably higher comorbidity in recent years led to increased use of incontinent UD in Germany, while continent UD appears to be underused in the US. Mortality and transfusion rates were significantly lower in the US within a shorter hospital stay. PMID- 29468603 TI - Glucocorticoids and the Risk of Peptic Ulcer Bleeding: Case-Control Analysis Based on Swiss Claims Data. AB - INTRODUCTION: Controversy exists as to whether glucocorticoids (GC) are ulcerogenic per se and may thus cause peptic ulcer bleeding (PUB) independent of concomitantly prescribed nonsteroidal anti-inflammatory drugs (NSAIDs). OBJECTIVE: To investigate the association between GC use and PUB with or without co-medication with NSAIDs. METHODS: We conducted a case-control study using administrative claims data from the Swiss health insurance company Helsana. We identified 1191 cases with incident PUB between 2012 and 2016 and matched up to 10 PUB-free controls to each case on age, sex, region and number of years insured with Helsana. We compared prior GC exposure between cases and controls using multivariate conditional logistic regression analyses controlling for several potential confounders. Patients with or without concomitant NSAID exposure were analysed separately. RESULTS: Patients with prior exposure to both GC and NSAIDs were five times more likely to experience PUB than patients who neither used GC nor NSAIDs (adjusted odds ratio [adj. OR] 4.80, 95% CI 3.55-6.71). Although the risk of PUB among patients who used NSAIDs without GC was increased threefold (adj. OR 3.20, 95% CI 2.59-3.95), we observed only a moderately increased risk among patients who used GC alone without NSAIDs (adj. OR 1.63, 95% CI 1.20-2.42). CONCLUSIONS: The use of NSAIDs with or without GC was associated with a markedly higher risk of PUB compared with GC monotherapy. Use of GC alone was associated with a moderately increased risk of PUB, which might be causal or attributed to confounding by indication.

PMID- 29468606 TI - Repeat Sentinel Lymph Node Biopsy for Ipsilateral Breast Tumor Recurrence: A Systematic Review of the Results and Impact on Prognosis. AB - BACKGROUND: During recent years, an increasing number of patients with ipsilateral breast tumor recurrence (IBTR) and previous axillary surgery have undergone repeat sentinel lymph node biopsy (rSLNB). The influence of axillary nodal status on prognosis for IBTR patients remains unclear. This study aimed to evaluate the technical success rate, follow-up assessment, and prognostic value of rSLNB for patients with IBTR. METHODS: A systematic search conducted in MEDLINE, Embase, and the Cochrane Library up to July 2017 included all studies on rSLNB in IBTR. RESULTS: A total of 34 articles describing 1761 patients were identified. A repeat sentinel lymph node (rSLN) was successfully harvested from 64.3% of the patients with IBTR, and the rate was significantly higher for the patients who had a previous SLNB than for those who had a previous axillary lymph node dissection (ALND) (75.7% vs. 46.1%; P < 0.0001). The rSLN was tumor-positive for 18.2% of the rSLNs, 40% of which were harvested in basins other than the ipsilateral axilla. The negative predictive value of the rSLNB was 96.5%. Overall survival, reported for 21.5% of the patients, was 95.2% after a mean follow-up period of 29.6 months. CONCLUSION: The prognostic impact of rSLN-positive versus rSLN-negative IBTR remains unclear. Further studies are needed to fill in the gap in the management of lymph nodes for patients with IBTR. However, based on the current evidence, rSLNB is feasible for 64% of patients, especially after previous SLNB. With a negative predictive value of 96.5%, rSLNB appears to be highly specific, with substantial advantages over ipsilateral ALND in IBTR. PMID- 29468607 TI - The Patient-Reported Information Multidimensional Exploration (PRIME) Framework for Investigating Emotions and Other Factors of Prostate Cancer Patients with Low Intermediate Risk Based on Online Cancer Support Group Discussions. AB - BACKGROUND: This study aimed to use the Patient Reported Information Multidimensional Exploration (PRIME) framework, a novel ensemble of machine learning and deep-learning algorithms, to extract, analyze, and correlate self reported information from Online Cancer Support Groups (OCSG) by patients (and partners of patients) with low intermediate-risk prostate cancer (PCa) undergoing radical prostatectomy (RP), external beam radiotherapy (EBRT), and active surveillance (AS), and to investigate its efficacy in quality-of-life (QoL) and emotion measures. METHODS: From patient-reported information on 10 OCSG, the PRIME framework automatically filtered and extracted conversations on low intermediate-risk PCa with active user participation. Side effects as well as emotional and QoL outcomes for 6084 patients were analyzed. RESULTS: Side-effect profiles differed between the methods analyzed, with men after RP having more urinary and sexual side effects and men after EBRT having more bowel symptoms. Key findings from the analysis of emotional expressions showed that PCa patients younger than 40 years expressed significantly high positive and negative emotions compared with other age groups, that partners of patients expressed more negative emotions than the patients, and that selected cohorts (< 40 years, > 70 years, partners of patients) have frequently used the same terms to express their emotions, which is indicative of QoL issues specific to those cohorts. CONCLUSION: Despite recent advances in patient-centerd care, patient emotions are largely overlooked, especially in younger men with a diagnosis of PCa and their partners. The authors present a novel approach, the PRIME framework, to extract, analyze, and correlate key patient factors. This framework improves understanding of QoL and identifies low intermediate-risk PCa patients who require additional support. PMID- 29468608 TI - Adjuvant Therapy in the Treatment of Melanoma. PMID- 29468609 TI - Comparative Performance of the 7th and 8th Editions of the American Joint Committee on Cancer Staging Systems for Soft Tissue Sarcoma of the Trunk and Extremities. AB - BACKGROUND: The 8th edition American Joint Committee on Cancer (AJCC) staging for soft tissue sarcomas of the trunk/extremities divides T stage into four categories and upstages nodal disease to stage IV. We used the National Cancer Database (NCDB) to evaluate the prognostic power of the new system. METHODS: A total of 26,144 patients were identified from the NCDB from 2004 to 2013. Overall survival (OS) was compared using Kaplan-Meier and Cox proportional hazard models. RESULTS: Including T3 (10 cm > * >15 cm) and T4 (> 15 cm) categories resulted in an increased number of patients classified as stage III (5120 as IIIA [19.6%] and 4280 as IIIB [16.4%], vs. 7882 [30.1%] previously), and there was a small increase in the number of patients classified as stage IV (2776 [10.6%], vs. 2565 [9.8%] previously). In the 7th edition, the hazard ratio (HR) for death increases with stage, with large incremental increases between stages II-III and III-IV. In the 8th edition, the HR for death demonstrates smaller incremental increases between each stage. Five-year OS for 7th edition T1 and T2 patients was 78.8 and 58.8% (p < 0.01), respectively, versus 62.6, 53.5, and 56.1% for T2, T3, and T4 patients, respectively, in the 8th edition (p < 0.01). Patients with isolated nodal disease (n = 211) had a better 5-year OS than those with distant metastases (33.1% vs. 12.4%, p < 0.001). CONCLUSIONS: The AJCC 8th edition uses T stage to more accurately stratify OS in patients with large, high-grade tumors (T3/4) compared with those patients with T2 tumors, which facilitates risk assessment. The distinction between T3 and T4 may not be clinically significant. Patients with metastatic nodal disease have a survival outcome intermediate to those with stages III and IV disease.

PMID- 29468611 TI - Influences of Copper/Zinc-Loaded Montmorillonite on Growth Performance, Mineral Retention, Intestinal Morphology, Mucosa Antioxidant Capacity, and Cytokine Contents in Weaned Piglets. AB - The effects of copper/zinc-loaded montmorillonite (Cu/Zn-Mt) on growth performance, mineral retention, intestinal morphology, mucosa antioxidant capacity, and cytokine contents in weaned piglets were investigated in the present study. One hundred eight piglets weaned at 21 +/- 1 days of age (Duroc * Landrace* Yorkshire; average initial weight of 6.36 kg) were allotted to three treatments for 2 weeks. The three treatments were as follows: (1) control group: basal diet; (2) Cu/Zn-Mt group: basal diet + 39 mg/kg Cu and 75 mg/kg Zn as Cu/Zn Mt; (3) Cu + Zn + Mt group: basal diet + mixture of CuSO4, ZnSO4, and Mt (equal amount of Cu, Zn, and Mt to the Cu/Zn-Mt group). Each treatment had six pens of six piglets. The results showed that as compared with the control group and the Cu + Zn + Mt group, Cu/Zn-Mt supplementation increased (P < 0.05) the average daily gain and the gain/feed ratio; Cu/Zn-Mt supplementation increased (P < 0.05) the Cu and Zn concentrations in serum, jejunum, and ileum mucosa, villus height, the ratio of villus height to crypt depth, and the activities of SOD, GSH-Px, and IL-10 levels, and decreased the malondialdehyde concentrations in the jejunum and ileum, and intestinal IL-1beta, IL-6, and TNF-alpha levels. Moreover, supplementation with the mixture of CuSO4, ZnSO4, and Mt had no effect on the growth performance, but increased the mucosa Cu and Zn concentrations, intestinal morphology, antioxidant capacity, and immune function in the duodenum, while it had no effect on the above indexes in the jejunum and ileum. The results indicated that Mt could be used as a controlled carrier for Cu and Zn, which made Cu/Zn-Mt have better biological activities in the intestine than the mixture of Cu, Zn, and Mt. PMID- 29468612 TI - Selenium-Enriched Saccharomyces cerevisiae Reduces the Progression of Colorectal Cancer. AB - Colorectal cancer is one of the most common causes of mortality in the world while malnutrition is responsible for one third of the problem. Selenium has been recommended for prevention of colorectal cancer. The present study was conducted to investigate the effect of selenium-enriched Saccharomyces cerevisiae in reducing colorectal cancer progression in rats. Five groups of 170-200-g weight rats (n = 40) including healthy and cancer controls, Saccharomyces cerevisiae, selenium, and selenium-enriched Saccharomyces cerevisiae-treated groups were examined. All animals except healthy control group received 40 mg 1,2 dimethylhydrazine (DMH) per kilogram weight of rat twice a week. The healthy group received normal saline, and synchronously, selenium group received soluble selenium (4 mg/mL), Saccharomyces cerevisiae and selenium-enriched groups received yeast with the density of 5 * 108 CFU/mL by daily gavage. All treatments were carried out for 5 weeks after the last injection. Animals were autopsied, and aberrant crypt foci (ACF) of ejected colon were studied in the 40th week. Microscopic sections were prepared for hematoxylin and eosin. Furthermore, immunohistochemical staining of CD31, BCL2, and P53 antibodies was performed. Macroscopic and microscopic evaluations showed that DMH had the least destructive effect in selenium-enriched Saccharomyces cerevisiae group compared to other groups. Selenium-enriched Saccharomyces cerevisiae reduces colorectal cancer progression by various mechanisms such as reduction in the number and size of ACF and alteration in the function of the proteins such as P53, BCL2, and CD31. PMID- 29468613 TI - Effects of Dietary Zinc Oxide Nanoparticles on Growth, Diarrhea, Mineral Deposition, Intestinal Morphology, and Barrier of Weaned Piglets. AB - This study was conducted to investigate effects of dietary zinc oxide nanoparticles (nano-ZnOs) on growth, diarrhea rate, mineral deposition (Zn, Fe, and Mn), intestinal morphology, and barrier of weaned piglets. A total of 384 weaned piglets (Duroc * Landrace * Yorkshire) in 4 groups were fed a basal diet supplemented with 0, 400, and 800 mg/kg nano-ZnOs or 3000 mg/kg ZnO for 14 days. Compared with the control group, 800 mg/kg nano-ZnOs and 3000 mg/kg ZnO significantly increased average daily gain and decreased diarrhea rate of weaned piglets. There was no significant difference among ZnO and nano-ZnO groups. ZnO and nano-ZnOs did not affect serum activities of glutamic oxalacetic transaminase, glutamic-pyruvic transaminase, and lactate dehydrogenase. However, ZnO and 800 mg/kg nano-ZnOs significantly increased zinc concentrations in plasma, liver, pancreas, and tibia, without affecting Fe and Mn concentrations. Compared with the control group, 800 mg/kg nano-ZnOs significantly reduced plasma diamine oxidase activity, decreased total aerobic bacterial population in mesenteric lymph node, enhanced mRNA expressions of occludin, ZO-1, IL-1beta, IL 10, TNF-alpha, and ki67 in ileal mucosa, and increased villous height, width, crypt depth, and surface area. Compared to ZnO group, 800 mg/kg nano-ZnOs significantly decreased aerobic bacterial population, enhanced mRNA expressions of occludin, IL-1beta, IL-10, and TNF-alpha, and reduced fecal zinc concentration. These results indicated that 800 mg/kg nano-ZnOs might be a potential substitute for 3000 mg/kg ZnO in diets of weaned piglets. PMID- 29468614 TI - Association of the CAN score with the FRAIL scale in community dwelling older adults. AB - BACKGROUND: Frailty is a state of vulnerability to stressors which results in higher morbidity, mortality and healthcare utilization. The FRAIL scale is used as a validated screening for frailty. The Care Assessment Need (CAN) score is automatically generated from electronic health record data using a statistical model that includes data elements similar to the deficit accumulation model for frailty and predicts risk for hospitalization and/or mortality. AIM: To determine the correlation of the CAN score with the FRAIL scale. METHODS: A cross-sectional study of 503 community-dwelling older adults. We compared the FRAIL scale with the CAN score. RESULTS: The CAN score was significantly different between robust, prefrail and frail. Post hoc analysis revealed significant increases in scores from robust to prefrail and frail groups, in that order. The CAN score and FRAIL scale showed a correlation. CONCLUSIONS: The CAN score show a moderate positive association with the FRAIL scale. PMID- 29468615 TI - Acute care hospital at different levels of intensity: the role of Geriatrician. AB - The traditional model of care is based on "disease-centered" management that requires the organization of the hospital in specialized wards, to which the patient is assigned for the main disease. The growing need to optimize economical and human resources and to promote a global approach to the patient has led to the setting up of the intensity of care model. It is a health system based on a "patient-centered" approach, where the hospital is organized in departments dedicated to patients with homogenous needs of care. In Italy, intensity of care model is currently being tested in the hospital organization, where three levels of intensity are proposed: low, medium and high. The purpose of the following review is to describe the role and importance of the Geriatrician in each of these care settings and to highlight the contradiction of a National Health System which promotes the geriatric approach to all types of patients, but does not invest in the formation and integration of the figure of the Geriatrician in clinical practice, condemning it to marginalization or even extinction. PMID- 29468616 TI - Does focal mechanical stimulation of the lower limb muscles improve postural control and sit to stand movement in elderly? AB - BACKGROUNDS: Imbalance in elderly is a common problem strictly related to fall. AIMS: This study investigates the possibility that a new protocol based on the focal mechanical muscle vibration may improve balance and stability in elderly. METHODS: Pre-post non-randomized clinical trial has been used. Patients referring postural disequilibrium with negative vestibular bed-side examinations have been treated with focal muscle vibration applied to quadriceps muscles and evaluated before and immediately after therapy and after 1 week and after 1 month with postural stabilometric examination and with an inertial measurement units during the time up and go test. RESULTS: Stabilometric analysis showed statistically significant differences in both the area (p = 0.01) and sway (p < 0.01) of the center of pressure during the close eyes tests. Moreover, the global time of the time up and go test was reduced (p < 0.05) and the rotation velocity was increased (p < 0.01). CONCLUSIONS: The findings confirm the beneficial role of focal muscle vibration in elderly patients improve postural stability and mobility.

AB - OBJECTIVE: Acute neuromuscular weakness related to hypokalemia is a readily treatable disorder associated with diverse aetiologies. In this study we aim to report clinical pattern and biochemical features to identify the different aetiologies of the hypokalemic neuromuscular weakness. METHODS: Retrospective reviews of the medical record were analysed. Evaluation included demography, clinical features, investigations performed to ascertain the aetiologies. All the patients were categorised in to 3 groups; Idiopathic hypokalemic paralysis (IHP), dengue associated hypokalemic paralysis (DHP) and secondary group (SG) which included renal tubular acidosis (RTA- 1 and 2), thyrotoxic periodic paralysis (TPP) and Gitelman's syndrome (GS). RESULTS: Forty patients were analysed and the mean age was 31.78 (range, 14-60) years and 35 (87.5%) were male.The underlying aetiologies comprised of IHP in 20, DHP in 12, RTA-2 in 4, RTA-1 in 2, TPP, GS in one each. Weakness on Medical Research Council (MRC) grade was 2.6+/-1.19 (range 0-4). Comparison of various clinical and laboratory parameters revealed that more patient in IHP and SG had recurrent attack (p=0.001). DHP group had low platelet (p=0.001), high creatine phosphokinase (CPK) (p=0.01) and serum glutamic oxaloacetic transaminase (SGOT) (p=0.008). SG had significantly lower serum potassium (p=0.04) and more time to improve (p=0.02). Recovery time correlated negatively with serum potassium (r=-0.44, p=0.004) and grade of weakness (r= 0.42,p=0.007). CONCLUSION: In half of the patients, secondary causes were identified. After IHP, the DHP emerged as second common cause in post monsoon season. SG had significantly lower serum potassium, recurrent attack and more time to improve. PMID- 29468619 TI - Outcome of Myasthenia gravis treated with high-dose prednisolone and azathioprine: A single centre ambispective study from India. AB - PURPOSE: Myasthenia gravis (MG) is treated with many disease modifying therapies, namely corticosteroids, thymectomy and immunosuppressants, alone or in various combinations. But still, till today no consensus over the optimum therapy for MG has been made. METHODS: Out of total 101 patients with MG, 37 patients fulfilled the inclusion criteria and in them we ambispectively studied factors affecting the outcome in MG treated, to induce leukopenia, with prednisolone (PSL) plus azathioprine(AZA), from January 1993 through July 2014. Patients were grouped according to the outcome: pharmacological remission (PR), complete stable remission (CSR), non-remitter and remitters with or without relapse. Their demographic characteristics, MGFA Class, dose of PSL and AZA, time to achieve remission, duration of remission, leukocyte counts, thymus status, follow-up duration, results of repetitive nerve stimulation, and side effects profile were compared. RESULTS: Total 81% patients remitted; PR (83%) was commoner than CSR (p=0.003). Factors favoring remission were early onset disease, therapeutic leukopenia (p=0.003) and longer follow-up (OR5, p=0.08); those associated with relapse were abnormal thymus (CI-1.1-3.4; p=0.09), MGFA class IIb (CI 0.9-3; p=0.09) and male gender. Side effects occurred in 48%. CONCLUSION: Aggressive therapy with prednisolone plus azathioprine induces remission in a high percentage of patients with generalized MG. PMID- 29468620 TI - Malnutrition in Acute Stroke Patients Stratified by Stroke Severity- A Hospital Based Study. AB - BACKGROUND: Stroke results in high mortality with tremendous health care burden. Malnutrition is frequently observed in patients after stroke. This study was designed to explore the nutritional status in the acute stage of stroke aiming at exploring factors related to malnutrition after stroke. METHODS: This was a hospital based, prospective, observational study recruiting cerebrovascular diseases patients hospitalized for acute management. Patients suffered from all kinds of cerebrovascular diseases hospitalized for management within 30 days after onset were consecutively recruited in the study hospitals. Stroke severity was evaluated by National Institutes of Health Stroke Scale, functional status by Barthel index, and global outcome by modified Rankin Scale. Cognitive function was evaluated by Mini-Mental State Examination. Nutritional status was assessed by Mini Nutritional Assessment (MNA), stratified by 1) adequate nutritional status, MNA >= 24; 2) protein-calorie malnutrition, MNA less than 17; 3) at risk of malnutrition, MNA between 17 and 23.5. RESULTS: There were 231 cerebral infarction patients recruited at 13.5 days (25-75%: 5.0-17.0) after stroke onset with mild stroke severity 71.4% and severe 10.4% with nasogastric tube insertion in 14%. Malnutrition was identified in 12.1% with 54.1% at risk of malnutrition. Factor related to malnutrition was severe stroke severity with dependency. Patients with old age, hypertension, and diabetes mellitus tended to have malnutrition or risk of malnutrition. CONCLUSION: Nutritional status was poor in stroke patients across all stroke severities within weeks. Further longitudinal outcome studies to identify the poor outcome and the evolution of nutritional status are warranted. PMID- 29468621 TI - Fusarium Brain Abscess in a Patient with Diabetes Mellitus and Liver Cirrhosis. AB - PURPOSE: Invasive mycosis caused by the Aspergillus, Fusarium, and Mucor can be fetal, especially in the immunocompromised patients with central nervous system (CNS) involvement. Here we present a case of CNS Fusarium infection, and this is the first reported case of Fusarium brain abscess in Taiwan. CASE REPORT: A 65 year-old woman presented with fever and conscious disturbance for 3 days. Neurological examination showed stupor consciousness, neck stiffness, multiple cranial nerves palsy, and bilateral Babinski signs. Magnetic resonance imaging showed multifocal lesions involving medulla oblongata, pons, bilateral cerebral peduncles, and bilateral cerebellar peduncles. Cerebrospinal fluid (CSF) study revealed neutrophil predominant pleocytosis, but both blood and CSF culture were negative. We treated patient with ceftriaxone and vancomycin initially as empiric therapy for suspected bacterial meningoencephalitis. However, chronic sinusitis with fungal ball and brain abscess were later found. Despite antifungal treatment and surgical intervention, patient expired 3 months after admission. Fungal culture of the brain abscess disclosed Fusarium species 2 weeks after her death. CONCLUSION: CNS Fusarium infection should be considered when an immunocompromised patient presenting with fever, conscious change, cranial nerve palsies, and angioinvasion suggested by brain imaging. To properly manage the disease, early effective antifungal therapy and neurosurgical intervention are important.

PMID- 29468623 TI - Isolated Basilar Artery Dissection with Ischemic Stroke: Report of 4 Cases. AB - PURPOSE: Isolated basilar artery dissection (BAD) is a rare cause of ischemic stroke. Since the clinical presentations and imaging findings could be non specific and subtle, the diagnosis may be difficult. Here, we presented four cases of isolated BAD with acute ischemic stroke. CASE REPORT: Four patients (age, 22 to 57 years) experienced acute onset of hemiparesis and/or vertigo with half of them having initial headache. Acute infarct was noted at pons or thalamus. Three cases needed more than one imaging modality or serial follow-up imaging to confirm a diagnosis of isolated BAD. Vascular tapering and/or false lumen restrictive to basilar artery were the commonest imaging findings. Three of our patients received anticoagulant without recurrent infarct or hemorrhagic complication. All of the patients had good functional outcome with modified Ranking scale scoring 1. CONCLUSION: Isolated BAD may cause variable clinical manifestations and the outcome can be favorable. Application of different and advanced imaging studies with serial image follow-up are useful to confirm the diagnosis. PMID- 29468624 TI - Factors associated with preparedness of the US healthcare system to respond to a pediatric surge during an infectious disease pandemic: Is our nation prepared? AB - OBJECTIVE: Recent incidents have demonstrated that the US health system is unprepared for infectious pandemics resulting in a pediatric surge. Development of efficient plans and a structured and coordinated regional response to pediatric pandemic surge remains an opportunity. To address this gap, we conducted a literature review to assess current efforts, propose a response plan structure, and recommend policy actions. DESIGN: A literature review, utilizing MEDLINE and PubMed, through March 2017 identified articles regarding infectious disease pandemics affecting the US pediatric population. After review of current literature, a proposed response plan structure for a pediatric pandemic surge was designed. RESULTS: Inclusion and exclusion criteria reduced an initial screening of 1,787 articles to 162 articles. Articles ranged in their discussion of pediatric pandemic surge. Review of the articles led to the proposal of organizing the results according to 4 S's; (1) Structure, (2) Staff, (3) Stuff (Resources), and (4) Space. CONCLUSION: The review has supported the concern that the US health system is unprepared for a pediatric surge induced by infectious disease pandemics. Common themes suggest that response plans should reflect the 4Ss and national guidelines must be translated into regional response systems that account for local nuances. PMID- 29468625 TI - Analysis of the antidote requirements and outcomes of different radionuclide decorporation strategies for a scenario of a "dirty bomb" attack. AB - OBJECTIVE: In radiological emergencies, there is a risk of radionuclide incorporation. The radiological doses absorbed can be reduced by decorporation treatment. Antidote requirements depend on the scenario and treatment strategy ("urgent approach": immediate treatment of all patients with possible incorporation; "precautionary approach": treatment only after confirmation of incorporation). We calculated the number of daily antidote doses for different scenarios and the differences in outcome for both treatment strategies. DESIGN: The number of potentially contaminated victims was varied from 1,000 to 60,000 (a maximum that might seem plausible for "dirty bomb" scenarios in Germany), the proportion of patients actually needing decorporation treatment from 0.1 percent to 100 percent, the radioactive screening capacities from 250 to 2,500 people/day and treatment duration from 10 to 90 days. The outcomes were assessed as total statistical lifetime saved assuming an inhalation of 1 mCi cesium-137 and the achievable dose reductions by a Prussian Blue treatment. RESULTS: Assuming 1 percent of the potentially contaminated people actually needing treatment, applying an "urgent approach" the requirements for 1,000 victims range from 1,100 to 3,400 and for 60,000 victims from 489,000 to 4,400,000 daily doses, depending on treatment duration and screening capacities. The "urgent approach" is associated with larger stockpile requirements than the "precautionary approach", up to several hundred times in large-scale scenarios if the proportion of people actually needing treatment is low. The impact of the screening capacities is particularly important in large-scale scenarios, a low proportion of people needing treatment and extended treatment duration. The outcome is better for an "urgent approach" particularly in large-scale scenarios and low screening capacities. CONCLUSIONS: If only a small fraction of the victims actually needs treatment, their timely identification by enhancing screening capacities may be the most efficacious way to reduce antidote requirements. In large-scale scenarios, it might be necessary to abandon the medically preferable "urgent approach" for an antidote-sparing "precautionary approach". PMID- 29468626 TI - Deployment of field hospitals to disaster regions: Insights from ten medical relief operations spanning three decades. AB - OBJECTIVE: The Israeli Defense Force (IDF) Medical Corps developed a model of airborne field hospital. This model was structured to deal with disaster settings, requiring self-sufficiency, innovation and flexible operative mode in the setup of large margins of uncertainty regarding the disaster environment. The current study is aimed to critically analyze the experience, gathered in ten such missions worldwide. METHODS: Interviews with physicians who actively participated in the missions from 1988 until 2015 as chief medical officers combined with literature review of principal medical and auxiliary publications in order to assess and integrate information about the assembly of these missions. RESULTS: A body of knowledge was accumulated over the years by the IDF Medical Corps from deploying numerous relief missions to both natural (earthquake, typhoon, and tsunami), and man-made disasters, occurring in nine countries (Armenia, Rwanda, Kosovo, Turkey, India, Haiti, Japan, Philippines, and Nepal). This study shows an evolutionary pattern with improvements implemented from one mission to the other, with special adaptations (creativity and improvisation) to accommodate logistics barriers. CONCLUSION: The principals and operative function for deploying medical relief system, proposed over 20 years ago, were challenged and validated in the subsequent missions of IDF outlined in the current study. These principals, with the advantage of the military infrastructure and the expertise of drafted civilian medical professionals enable the rapid assembly and allocation of highly competent medical facilities in disaster settings. This structure model is to large extent self-sufficient with a substantial operative flexibility that permits early deployment upon request while the disaster assessment and definition of needs are preliminary. PMID- 29468627 TI - Terrorism reports: The tip of the iceberg. AB - IMPORTANCE: Medical impact of terror is a public health issue as the threat is growing all over the world. OBJECTIVE: Our objective was to compare the number of injured and incidents in the three different databases and reports [Global Terrorism Database (GTD), Israeli Security Agency (ISA) and National Insurance Institute (NII)] in Israel. DESIGN: Retrospective study. SETTING: Analyses of three different databases (GTD, ISA and NII) and basic comparison. MAIN OUTCOME(S) AND MEASURE(S): The victims reimbursed for medical expenses are the largest population. The number of injured as described by GTD and ISA database are less important. The 2010-2013 years are marked by more incidents recognized in Israel vs GTD assessment (except in 2014). CONCLUSIONS AND RELEVANCE: The number of victims being reimbursed for medical and mental health services is radically different from the GTD and the ISA reports. Public Health specialists should be advised of this phenomenon to deliver their right approach (including mental health) to growing threat and develop new definition of victim of terror.

AB - OBJECTIVE: This study seeks to understand the acceptability and perceived utility of unmanned aerial vehicle (UAV) technology to Mass Casualty Incidents (MCI) scene management. DESIGN: Qualitative questionnaires regarding the ease of operation, perceived usefulness, and training time to operate UAVs were administered to Emergency Medical Technicians (n = 15). SETTING: A Single Urban New England Academic Tertiary Care Medical Center. PARTICIPANTS: Front-line emergency medical service (EMS) providers and senior EMS personnel in Incident Commander roles. CONCLUSIONS: Data from this pilot study indicate that EMS responders are accepting to deploying and operating UAV technology in a disaster scenario. Additionally, they perceived UAV technology as easy to adopt yet impactful in improving MCI scene management. PMID- 29468629 TI - Emergency operations program is an excellent platform to deal with in-hospital operation disaster. AB - Described herein is the utilization of the hospital's Emergency Operations Plan and incident command structure to mitigate damage caused by the sudden loss of the heating, ventilation, and air conditioning system within the entire operating room suite. The ability to ameliorate a devastating situation that occurred during working hours at a busy Level II trauma center can be ascribed to the dedication of the leadership and clinical teams working seamlessly together. Their concerted efforts were augmented by adherence to an established protocol that had been thoroughly substantiated and practiced during numerous training simulations. This resulted in successful and timely resolution of an internal crisis that crippled the surgical capabilities of the sole trauma center in the county. After thorough investigation and identification of the issues that contributed to the malfunction, redundancies were built into the system to ensure that a similar incident did not occur again.

PMID- 29468631 TI - High-dose melphalan-based sequential conditioning chemotherapy followed by allogeneic haematopoietic stem cell transplantation in adult patients with relapsed or refractory acute myeloid leukaemia. AB - Considering the unsatisfactory results of salvage therapies for patients with relapsed/refractory acute myeloid leukaemia (R/R-AML), their value before allogeneic haematopoietic stem cell transplantation (HSCT) remains questionable. However, direct allogeneic HSCT following established conditioning regimens applied in patients with R/R-AML during active disease has been equally disappointing. In this retrospective observational study, high-dose melphalan, as part of a sequential preparative regimen, followed by a total body irradiation (4 * 2 Gy)-based or a treosulfan-based dose-adapted conditioning therapy for allogeneic HSCT was administered to 292 adult patients (median age 56 years, range 17-74) with primary refractory (144 patients), secondary refractory (97 patients) or relapsed AML (51 patients). Overall survival rates at 3 years were 34%, 29% and 41%, respectively. Risk factors associated with an inferior survival were higher age, transplantation from a human leucocyte antigen-mismatched donor and high disease burden. Patients transplanted with blast infiltration <20% showed a notable survival rate of 51% at 3 years. In particular, patients with primary refractory AML showed a more favourable outcome when transplanted early during their disease course. Thus, high-dose melphalan-based sequential conditioning chemotherapy followed by an allogeneic HSCT is feasible and enables long-term remission to be achieved in a substantial proportion of patients with active R/R-AML. PMID- 29468632 TI - Autonomic function test in progressive lacunar infarction. AB - OBJECTIVE: Neurological progression is a major problem in managing the patients with acute lacunar infarction. The purpose of this was to investigate whether autonomic dysfunction is associated with neurological progression in patients with acute lacunar infarction. MATERIALS AND METHODS: The study comprised 60 patients with acute lacunar infarction. All enrolled subjects underwent autonomic function tests including the 30 degrees head-up tilt test, Valsalva test, heart rate response to deep breathing, and sympathetic skin response. The primary endpoint is the neurological progression, and the secondary endpoint is the 3 month outcome. RESULTS: Increased initial National Institute of Health stroke scale (NIHSS), decreased time to admission from onset, decreased rise of heart rate in the 30 degrees head-up tilt test, abnormal blood pressure response in the Valsalva test, and decreased rise of systolic blood pressure in stage IV of the Valsalva test are associated with neurological progression of acute lacunar infarction; an abnormal blood pressure response in the Valsalva test is significant in logistic regression analysis of neurological progression. Advanced age, increased initial NIHSS and modified Rankin scale, decreased expiration/inspiration ratio of heart rate to deep breathing, decreased rise of systolic blood pressure in stage IV of the Valsalva test, and neurological progression were associated with an unfavorable 3-month outcome; neurological progression was significant in logistic regression analysis of 3-month outcome. CONCLUSIONS: An abnormal blood pressure change in the Valsalva test is associated with neurological progression in patients with acute lacunar infarction, and neurological progression can induce an unfavorable 3-month outcome. PMID- 29468633 TI - Prostaglandin gel versus oxytocin - prelabour rupture of membranes at term - A randomised controlled trial. AB - BACKGROUND: Pre-labour rupture of membranes (PROM) at term is a common event with early induction of labour reducing infectious morbidity without increasing the caesarean rate. Syntocinon is commonly used for induction but prostaglandins are also routinely used. Large studies have shown no difference in the maternal and neonatal outcomes with either method. AIM: To assess the safety and efficacy of vaginal prostaglandin (PG) compared to syntocinon for induction of labour in term PROM. METHOD: This was a single-centre randomised controlled trial at Ipswich Hospital of women presenting at >=37 weeks gestation with PROM. Women were randomised and managed in labour as per local guidelines. Analysis was by intention to treat. RESULTS: One hundred and eighty-four women were recruited, 90 in the PG group and 94 in the oxytocin group. Women in both arms were of similar demographics and 53% of women in the PG group did not require any oxytocin. There was a statistically significant lower incidence of fetal heart rate abnormality in the PG group, 4.4% versus 12.8%. There was no difference in epidural use, caesarean section, maternal infection, admission to special care nursery or neonatal sepsis. Time to onset of labour was significantly longer in the PG group, 25.7 h versus 19.7 h but with no difference in the length of first stage. Maternal satisfaction was high in both groups with no significant difference in breastfeeding rates. CONCLUSION: Induction of labour with oxytocin or vaginal prostaglandins are safe and efficacious options for women in the context of PROM at term. PMID- 29468634 TI - Cognitive decline in the middle-aged after surgery and anaesthesia: results from the Wisconsin Registry for Alzheimer's Prevention cohort. AB - Surgery and anaesthesia might affect cognition in middle-aged people without existing cognitive dysfunction. We measured memory and executive function in 964 participants, mean age 54 years, and again four years later, by when 312 participants had had surgery and 652 participants had not. Surgery between tests was associated with a decline in immediate memory by one point (out of a maximum of 30), p = 0.013: memory became abnormal in 77 out of 670 participants with initially normal memory, 21 out of 114 (18%) of whom had had surgery compared with 56 out of 556 (10%) of those who had not, p = 0.02. The number of operations was associated with a reduction in immediate memory on retesting, beta coefficient (SE) 0.08 (0.03), p = 0.012. Working memory decline was also associated with longer cumulative operations, beta coefficient (SE) -0.01 (0.00), p = 0.028. A reduction in cognitive speed and flexibility was associated with worse ASA physical status, beta coefficient (SE) 0.55 (0.22) and 0.37 (0.17) for ASA 1 and 2 vs. 3, p = 0.035. However, a decline in working memory was associated with better ASA physical status, beta coefficient (SE) -0.48 (0.21) for ASA 1 vs. 3, p = 0.01. PMID- 29468635 TI - Strategies to improve recruitment to randomised trials. AB - BACKGROUND: Recruiting participants to trials can be extremely difficult. Identifying strategies that improve trial recruitment would benefit both trialists and health research. OBJECTIVES: To quantify the effects of strategies for improving recruitment of participants to randomised trials. A secondary objective is to assess the evidence for the effect of the research setting (e.g. primary care versus secondary care) on recruitment. SEARCH METHODS: We searched the Cochrane Methodology Review Group Specialised Register (CMR) in the Cochrane Library (July 2012, searched 11 February 2015); MEDLINE and MEDLINE In Process (OVID) (1946 to 10 February 2015); Embase (OVID) (1996 to 2015 Week 06); Science Citation Index & Social Science Citation Index (ISI) (2009 to 11 February 2015) and ERIC (EBSCO) (2009 to 11 February 2015). SELECTION CRITERIA: Randomised and quasi-randomised trials of methods to increase recruitment to randomised trials. This includes non-healthcare studies and studies recruiting to hypothetical trials. We excluded studies aiming to increase response rates to questionnaires or trial retention and those evaluating incentives and disincentives for clinicians to recruit participants. DATA COLLECTION AND ANALYSIS: We extracted data on: the method evaluated; country in which the study was carried out; nature of the population; nature of the study setting; nature of the study to be recruited into; randomisation or quasi-randomisation method; and numbers and proportions in each intervention group. We used a risk difference to estimate the absolute improvement and the 95% confidence interval (CI) to describe the effect in individual trials. We assessed heterogeneity between trial results. We used GRADE to judge the certainty we had in the evidence coming from each comparison. MAIN RESULTS: We identified 68 eligible trials (24 new to this update) with more than 74,000 participants. There were 63 studies involving interventions aimed directly at trial participants, while five evaluated interventions aimed at people recruiting participants. All studies were in health care.We found 72 comparisons, but just three are supported by high-certainty evidence according to GRADE.1. Open trials rather than blinded, placebo trials. The absolute improvement was 10% (95% CI 7% to 13%).2. Telephone reminders to people who do not respond to a postal invitation. The absolute improvement was 6% (95% CI 3% to 9%). This result applies to trials that have low underlying recruitment. We are less certain for trials that start out with moderately good recruitment (i.e. over 10%).3. Using a particular, bespoke, user-testing approach to develop participant information leaflets. This method involved spending a lot of time working with the target population for recruitment to decide on the content, format and appearance of the participant information leaflet. This made little or no difference to recruitment: absolute improvement was 1% (95% CI -1% to 3%).We had moderate-certainty evidence for eight other comparisons; our confidence was reduced for most of these because the results came from a single study. Three of the methods were changes to trial management, three were changes to how potential participants received information, one was aimed at recruiters, and the last was a test of financial incentives. All of these comparisons would benefit from other researchers replicating the evaluation. There were no evaluations in paediatric trials.We had much less confidence in the other 61 comparisons because the studies had design flaws, were single studies, had very uncertain results or were hypothetical (mock) trials rather than real ones. AUTHORS' CONCLUSIONS: The literature on interventions to improve recruitment to trials has plenty of variety but little depth. Only 3 of 72 comparisons are supported by high certainty evidence according to GRADE: having an open trial and using telephone reminders to non-responders to postal interventions both increase recruitment; a specialised way of developing participant information leaflets had little or no effect. The methodology research community should improve the evidence base by replicating evaluations of existing strategies, rather than developing and testing new ones. PMID- 29468636 TI - Oxidation catalysis by iron and manganese porphyrins within enzyme-like cages. AB - Inspired by natural heme-proteins, scientists have attempted for decades to design efficient and selective metalloporphyrin-based oxidation catalysts. Starting from the pioneering work on small molecule mimics in the late 1970s, we have assisted to a tremendous progress in designing cages of different nature and complexity, able to accommodate metalloporphyrins. With the intent of tuning and controlling their reactivity, more and more sophisticated and diverse environments are continuously exploited. In this review, we will survey the current state of art in oxidation catalysis using iron- and manganese-porphyrins housed within designed or engineered protein cages. We will also examine the innovative metal-organic framework (MOF) systems, exploited to achieving an enzyme-like environment around the metalloporphyrin cofactor.

PMID- 29468638 TI - Accuracy of point-of-care HbA1c testing in pregnant women. AB - BACKGROUND: In New Zealand, it is recommended that all pregnant women have a haemoglobin A1c (HbA1c) test performed with their booking antenatal bloods to identify previously unrecognised diabetes. However, screening rates in some groups are low. Use of a point-of-care device may improve compliance with screening. AIM: To assess the accuracy of the COBAS b101 point-of-care system referenced against a laboratory method, for measurement of HbA1c levels in pregnant women. MATERIALS AND METHODS: Convenience sample of 40 obese pregnant women enrolled in a clinical trial. HbA1c was assayed in paired capillary and venous whole blood samples using the COBAS b101 point-of-care system and Primus Ultra2 high performance liquid chromatography laboratory analyser, respectively. The accuracy of the point-of-care system was assessed by Bland-Altman analysis. RESULTS: The mean (SD) laboratory HbA1c was 35.9 (2.0) mmol/mol. The COBAS b101 point-of-care system, compared with the laboratory reference method, had a small negative bias for HbA1c (-1.0 mmol/mol, 95% CI -2.0 to -0.03, P = 0.03) and relatively wide 95% limits of agreement (-7.2 to 5.1 mmol/mol). CONCLUSION: In conclusion, we found that in pregnancy, the COBAS b101 point-of-care system has a small negative bias and modest point accuracy for HbA1c. When used to screen for previously unrecognised diabetes in pregnancy, appropriate COBAS b101 HbA1c point of-care HbA1c thresholds for a negative and positive result are 7 mmol/mol below and 5 mmol/mol above the clinical threshold, respectively. Values between these limits should be confirmed by laboratory testing. PMID- 29468639 TI - Factor XIa-triggered thrombin generation in severe haemophilia A. PMID- 29468640 TI - Prevalence and Preventability of Drug-Related Hospital Readmissions: A Systematic Review. AB - OBJECTIVES: To summarize the evidence on the prevalence and preventability of drug-related hospital readmissions. DESIGN: A systematic review was performed of studies that examined drug-related hospital readmissions. PubMed, EMBASE, and the Cochrane Library were searched from inception through August 2016. Reference lists and a citation analysis on Web of Science and Scopus were also consulted. Two reviewers extracted study data with dual assessment of risk of bias. Prevalence and preventability of readmission due to drugs were calculated. Data were qualitatively summarized according to outcome. RESULTS: Nineteen studies met the eligibility criteria. Nine measured readmissions due to drug-related problems, seven due to adverse drug reactions, two due to adverse drug events, and one due to drug-drug interactions. Rates of readmissions due to drugs varied from 3% to 64% (median 21%, interquartile range (IQR) 14-23%). Readmissions were deemed preventable in 5% to 87% of cases (median 69%, IQR 19-84%). Evidence regarding the risk factors for drug-related readmissions and drugs causing these readmissions was inconsistent. CONCLUSION: Although studies show high variability in prevalence and preventability of drug-related hospital readmissions, readmissions due to drugs seem to occur often, especially in older adults. Further research is needed to specify the causes of preventable readmissions and implement effective interventions to reduce medication-related hospital admissions.

PMID- 29468642 TI - Sensory distribution of the lateral femoral cutaneous nerve block - a randomised, blinded trial. AB - BACKGROUND: The lateral femoral cutaneous nerve (LFCN) block may be used for post operative pain management in patients undergoing total hip arthroplasty. The aim of this trial was to investigate the sensory coverage of the posterior and the lateral incision lines and the involvement of the femoral nerve after an LFCN block. METHODS: The study was a randomised, blinded trial in 20 healthy volunteers. All subjects received a bilateral LFCN block randomised to 8 ml ropivacaine on the right side and 8 ml isotonic saline on the left side, or vice versa. An orthopaedic surgeon depicted the incision lines (invisible to the investigators) prior to block performance. The distribution of the blocked area and the coverage of the incision lines were assessed with temperature discrimination and pinprick test before unblinding the incision lines. Pain during tonic heat stimulation and involvement of the femoral nerve by measuring quadriceps strength were assessed. RESULTS: The mean difference in block coverage of the posterior (primary outcome) and the lateral incision lines tested with temperature discrimination were 5.8% (95% CI: -2.2 to 14.0%, P = 0.146) and 18.9% (95% CI: 6.5-31.4%, P = 0.005), respectively, comparing the active with the placebo side. A varying anatomic distribution area was observed. No clinically significant differences for experimental pain and quadriceps muscle strength were found. The block failure rate was 15%. CONCLUSION: An LFCN block consisting of 8 ml 0.75% ropivacaine had limited coverage of the posterior and lateral incision lines.

AB - OBJECTIVES: Spasticity is a common and disabling feature of amyotrophic lateral sclerosis (ALS). There are currently no validated ALS-specific measures of spasticity. The aim of this study was to develop and use a self-report outcome measure for spasticity in ALS. METHODS: Following semi-structured interviews with 11 ALS patients, a draft scale was administered across ALS clinics in the UK. Internal validity of the scale was examined using the Rasch model. The numerical rating scale (NRS) for spasticity and Leeds Spasticity scale (LSS) were co administered. The final scale was used in a path model of spasticity and quality of life. RESULTS: A total of 465 patients (mean age 64.7 years (SD 10), 59% male) with ALS participated. Spasticity was reported by 80% of subjects. A pool of 71 items representing main themes of physical symptoms, negative impact and modifying factors was subject to an iterative process of item reduction by Rasch analysis resulting in a 20-item scale-the Spasticity Index for ALS (SI-ALS)-which was unidimensional and free from differential item functioning. Moderate correlations were found with LSS and NRS-spasticity. Incorporating the latent estimate of spasticity into a path model, greater spasticity reduced quality of life and motor function; higher motor function was associated with better quality of life. CONCLUSIONS: The SI-ALS is a disease-specific self-report scale, which provides a robust interval-level measure of spasticity in ALS. Spasticity has a substantial impact on quality of life in ALS. PMID- 29468645 TI - Humoral immune failure defined by immunoglobulin class and immunoglobulin G subclass deficiency is associated with shorter treatment-free and overall survival in Chronic Lymphocytic Leukaemia. AB - Immune dysfunction attributed to hypogammaglobulinaemia is common in chronic lymphocytic leukaemia (CLL) and infection is a major contributor to morbidity and mortality. A higher incidence of multiple immunoglobulin and immunoglobulin G (IgG) subclass deficiency was associated with more advanced disease (P < 0.001 and P < 0.001, respectively) in a cohort of 147 CLL patients. Multiple immunoglobulin and IgG subclass deficiency were significantly associated with shorter treatment-free survival (TFS) (P < 0.001 and P = 0.006, respectively). The association between disease stage and immune dysfunction demonstrated by these data suggest aspects of immune deficiency correlate with disease severity and may be associated with shorter TFS in CLL.

PMID- 29468647 TI - Brentuximab vedotin prior to allogeneic stem cell transplantation in Hodgkin lymphoma: a report from the EBMT Lymphoma Working Party. AB - Brentuximab vedotin (BV) is an anti-CD30 antibody-drug conjugate. Preliminary data suggest that BV might improve outcomes after allogeneic stem cell transplantation (SCT) for Hodgkin lymphoma (HL) when used as pre-transplant salvage therapy. Between 2010 and 2014, 428 adult patients underwent an allogeneic SCT for classical HL at participating centres of the European Society for Blood and Marrow Transplantation. We compared the outcomes of 210 patients who received BV prior to allogeneic SCT with that of 218 patients who did not receive BV. The median follow-up for survivors was 41 months. Patients in the BV group were more heavily pre-treated (median pre-allograft treatment lines: 4 vs. 3). The two groups were comparable in terms of disease status, performance status, comorbidities, prior autologous SCT, type of donor, conditioning and in vivo T cell depletion. In multivariate analysis, pre-allograft BV had no impact on acute graft-versus-host disease (GVHD), non-relapse mortality, cumulative incidence of relapse, progression-free survival or overall survival (OS), but significantly reduced the risk of chronic GVHD (hazard ratio = 0.64; 95% confidence interval = 0.45-0.92; P < 0.02). Older age, poor performance status, use of pre-transplant radiotherapy and active disease at SCT adversely affected OS. Patients allografted for HL after prior exposure to BV do not have a superior outcome after allogeneic SCT except for a lower risk of chronic GVHD. However, BV may improve the outlook of allogeneic SCT by helping otherwise refractory patients to achieve a more favourable disease status, facilitating allotransplant success.

PMID- 29468649 TI - Is anticoagulating haemodialysis patients with non-valvular atrial fibrillation too risky? AB - There is an increasing understanding of the risks from atrial fibrillation (AF) in the current era. In patients with end-stage renal disease (ESRD) on dialysis, the prevalence of AF is significantly higher compared to the general population and those with earlier stages of CKD. Although anticoagulation of these patients may seem appropriate, there is a lack of conclusive evidence that it provides the same protection from thromboembolic complications as it does in patients not on dialysis. In addition, the increased risk of bleeding in patients requiring dialysis makes the use of anticoagulants less favourable. This article aims to discuss the problem of AF in dialysis patients, summarise the current evidence around the use of oral anticoagulants for AF in ESRD and provide some practical suggestions on management of AF in the haemodialysis population. PMID- 29468650 TI - Hepatitis E virus - key points for the clinical haematologist. AB - In recent years there has been a paradigm shift in our understanding of the epidemiology and clinical features of hepatitis E virus (HEV) infection. Once classically described as an acute hepatitis associated with waterborne outbreaks in areas of poor sanitation, HEV is now recognised to be endemic in Europe and is probably zoonotic in origin. Evidence for transfusion-transmitted HEV has prompted the introduction of blood donor screening in a number of countries, but the risk to the haematology patient from food sources remains. The aim of this review therefore, is to equip the clinical haematologist with the knowledge required to diagnose HEV infection and to aid decision-making in patient management. The article also provides information on addressing patient concerns about their risk of acquiring hepatitis E and how this risk can be mitigated.

PMID- 29468652 TI - Response and survival for primary therapy combination regimens and maintenance rituximab in Waldenstrom macroglobulinaemia. AB - Waldenstrom macroglobulinaemia (WM) is a rare and incurable lymphoma. Comparative studies evaluating the efficacy of primary therapy in symptomatic WM patients have not been performed. In this study, we compared response and survival outcomes in WM patients who received primary therapy with cyclophosphamide dexamethasone-rituximab (CDR), bortezomib-dexamethasone-rituximab (BDR) and bendamustine-rituximab (Benda-R), as well as maintenance rituximab following primary therapy. Analyses were adjusted for relevant clinical factors associated with response and survival. Maintenance rituximab was analysed as a time-varying covariate. Our study included 182 patients, of which 57 (31%) received Benda-R, 87 (48%) BDR and 38 (21%) CDR; 116 (64%) received maintenance rituximab. The median time to best response was shorter for Benda-R and BDR than CDR (18, 20 and 30 months, respectively). Benda-R and BDR were associated with better median progression-free survival (PFS) than CDR (5.5, 5.8 and 4.8 years, respectively), and better 10-year overall survival rates (OS; 95%, 96% and 81%, respectively). Maintenance rituximab was associated with higher rates of major response (97% vs. 68%), and better median PFS (6.8 years vs. 2.8 years) and 10-year OS rate (84% vs. 66%) when compared to not receiving maintenance. Benda-R, BDR and maintenance rituximab associate with higher response rates and longer survival in WM patients than CDR and no maintenance, respectively.

PMID- 29468654 TI - Experimental evolution across different thermal regimes yields genetic divergence in recombination fraction but no divergence in temperature associated plastic recombination. AB - Phenotypic plasticity is pervasive in nature. One mechanism underlying the evolution and maintenance of such plasticity is environmental heterogeneity. Indeed, theory indicates that both spatial and temporal variation in the environment should favor the evolution of phenotypic plasticity under a variety of conditions. Cyclical environmental conditions have also been shown to yield evolved increases in recombination frequency. Here, we use a panel of replicated experimental evolution populations of D. melanogaster to test whether variable environments favor enhanced plasticity in recombination rate and/or increased recombination rate in response to temperature. In contrast to expectation, we find no evidence for either enhanced plasticity in recombination or increased rates of recombination in the variable environment lines. Our data confirm a role of temperature in mediating recombination fraction in D. melanogaster, and indicate that recombination is genetically and plastically depressed under lower temperatures. Our data further suggest that the genetic architectures underlying plastic recombination and population-level variation in recombination rate are likely to be distinct.

PMID- 29468657 TI - Comparative analysis of the outcomes of elective abdominal aortic aneurysm repair in England and Sweden. AB - BACKGROUND: There is substantial international variation in mortality after abdominal aortic aneurysm (AAA) repair; many non-operative factors influence risk adjusted outcomes. This study compared 90-day and 5-year mortality for patients undergoing elective AAA repair in England and Sweden. METHODS: Patients were identified from English Hospital Episode Statistics and the Swedish Vascular Registry between 2003 and 2012. Ninety-day mortality and 5-year survival were compared after adjustment for age and sex. Separate within-country analyses were performed to examine the impact of co-morbidity, hospital teaching status and hospital annual caseload. RESULTS: The study included 36 249 patients who had AAA treatment in England, with a median age of 74 (i.q.r. 69-79) years, of whom 87.2 per cent were men. There were 7806 patients treated for AAA in Sweden, with a median of age 73 (68-78) years, of whom 82.9 per cent were men. Ninety-day mortality rates were poorer in England than in Sweden (5.0 versus 3.9 per cent respectively; P < 0.001), but were not significantly different after 2007. Five year survival was poorer in England (70.5 versus 72.8 per cent; P < 0.001). Use of EVAR was initially lower in England, but surpassed that in Sweden after 2010. In both countries, poor outcome was associated with increased age. In England, institutions with higher operative annual volume had lower mortality rates. CONCLUSION: Mortality for elective AAA repair was initially poorer in England than Sweden, but improved over time alongside greater uptake of EVAR, and now there is no difference. Centres performing a greater proportion of EVAR procedures achieved better results in England. PMID- 29468655 TI - GPCRs in pulmonary arterial hypertension: tipping the balance. AB - Pulmonary arterial hypertension (PAH) is a progressive, fatal disease characterised by increased pulmonary vascular resistance and excessive proliferation of pulmonary artery smooth muscle cells (PASMC). GPCRs, which are attractive pharmacological targets, are important regulators of pulmonary vascular tone and PASMC phenotype. PAH is associated with the altered expression and function of a number of GPCRs in the pulmonary circulation, which leads to the vasoconstriction and proliferation of PASMC and thereby contributes to the imbalance of pulmonary vascular tone associated with PAH; drugs targeting GPCRs are currently used clinically to treat PAH and extensive preclinical work supports the utility of a number of additional GPCRs. Here we review how GPCR expression and function changes with PAH and discuss why GPCRs continue to be relevant drug targets for the disease. PMID- 29468658 TI - Dermatology hospitalists: a multicenter survey study characterizing the infrastructure of consultative dermatology in select American hospitals. AB - BACKGROUND: Although considered an outpatient specialty, dermatology plays an important role in inpatient medicine. We characterized the activity and structure of dermatology consultation services in select U.S. hospitals. METHODS: In this cross sectional study, a 31-question survey was distributed in person to 32 board certified dermatologists at the 2017 Society of Dermatology Hospitalists meeting. RESULTS: Thirty participants completed the survey (yield 93.8%). Most dermatology hospitalists spend 41-52 weeks on service (50%), with 37% spending between 11 and 30 weeks. Coverage was organized by continuous weeks (68%) or months (21%). While on service, hospitalists staffed an average of 4 outpatient clinics per week. Consultative teams also included internal medicine residents (43%), medical students (47%), pediatric residents (10%), and fellows from other specialties (27%). Consultation services saw approximately 3.7 new inpatients and 4.2 follow up inpatients per day, with daily rounds lasting approximately 2.6 hours. CONCLUSIONS: The results suggest that hospital dermatologists in the U.S. consider inpatient care their niche and devote a majority of their time staffing consults over clinic. The diverse composition of inpatient teams and the number of academic duties held by these physicians suggests they play an important role in medical education.

AB - Nasopharyngeal carcinoma (NPC) is an Epstein-Barr virus (EBV)-associated lymphoepithelioma. The aim of this study was to characterize the homogeneity and distinctness of the T-cell repertoires within and between primary and metastatic NPCs. We used ultra-deep sequencing of the hypervariably rearranged antigen binding CDR3 regions of T-cell receptor beta (TCRbeta ) to comprehensively profile the T-cell repertoires in NPC patients receiving definitive chemoradiotherapy with long-term follow-up. We observed not only various spatially heterogeneous patient-specific TCRbeta clone compositions that changed with time but also several commonly enriched TCRbeta subclones that were constantly shared between primary NPCs in the head and neck regions, locally recurrent tumors after treatment and later-developed distant metastatic tumors in the liver, lung and bone. Comparison of the overlap frequency of the T-cell clonality between TCRbeta repertoires enabled us to calculate the pairwise genetic distance between primary NPCs of different patients and different sites of metastatic or recurrent NPCs. The constructed NPC phylogeny clearly differentiated the low-risk patients without relapse from the high-risk patients with distant metastasis after chemoradiotherapy. In contrast to the rather low frequency of nonsilent somatic mutations in NPC cells, the degrees of similarity and divergence of NPC-infiltrating lymphocyte TCRbeta repertoires among different patients showed prognostication. Moreover, the persistent presence of commonly NPC-shared in-frame TCRbeta CDR3 gene sequences spatiotemporally identified in the NPC-infiltrating lymphocytes within varied EBV-positive NPCs and their metastases suggest the existence of frequently shared epitopes of neoantigens virally or nonvirally displayed on cancer cells, thereby providing opportunities for the development of precisely tumor-targeted immunotherapy for distant metastasis. PMID- 29468661 TI - Molecular and clinical studies in 8 patients with Temple syndrome. AB - Temple syndrome (TS14, #616222) is a rare imprinting disorder characterised by phenotypic features including pre- and postnatal growth retardation, muscular hypotonia and feeding difficulties in infancy, early puberty and short stature with small hands and feet and often truncal obesity. It is caused by maternal uniparental disomies, paternal deletions and primary imprinting defects that affect the chromosomal region 14q32 and lead to a disturbed expression of imprinted genes in this region. Here, we present detailed clinical data of 8 patients with Temple syndrome, 4 with an imprinting defect, 2 with an imprinting defect in a mosaic state as well as 1 complete and 1 segmental maternal uniparental disomy of chromosome 14. PMID- 29468662 TI - Predictive validity of spontaneous early infant movement for later cerebral palsy: a systematic review. AB - AIM: To systematically review the predictive validity of spontaneous early infant movements for later cerebral palsy (CP). METHOD: Cohort studies with published data to calculate predictive validity of early spontaneous movements for later CP were searched in four electronic databases: CINAHL, Embase, MEDLINE, and PsycINFO. RESULTS: Forty-seven studies met inclusion criteria. The Prechtl General Movements Assessment (GMA) during the fidgety period (10-20wks corrected age) had the strongest sensitivity: 97 per cent (95% confidence interval [CI] 93 99) and specificity: 89% (95% CI 83-93). The sensitivity and specificity of the Prechtl GMA during the writhing period (birth-6wks) was 93% (95% CI 86-96) and 59% (95% CI 45-71) respectively. Cramped-synchronized movements in the writhing period according to Prechtl had the best specificity (sensitivity: 70% [95% CI 54 82]; specificity: 97% [95% CI 74-100]). Hadders-Algra's method of assessing general movements had a pooled sensitivity and specificity of 89% (95% CI 66-97) and 81% (95% CI 64-91) respectively. Presence of asymmetric postures and movement quality/quantity were reported under the Hammersmith Infant Neurological Examination, Hammersmith Neonatal Neurological Examination, and Movement Assessment of Infants but had weak associations with later CP. INTERPRETATION: Fidgety movements assessed by the Prechtl GMA have the strongest predictive validity for later CP, but cannot be considered in isolation because of the presence of false positive results. WHAT THIS PAPER ADDS: Fidgety general movements (Prechtl) are most predictive for later cerebral palsy compared with other spontaneous movements. False positive results are high among all spontaneous movement assessments. PMID- 29468663 TI - Radiological imaging and bone marrow biopsy in staging of cutaneous B-cell lymphoma. PMID- 29468664 TI - Adverse mental health outcomes in a population-based cohort of survivors of childhood cancer. AB - BACKGROUND: The elevated risk for physical late effects in childhood cancer survivors (CCS) is well documented, but their risk for mental health problems is less well described. METHODS: The authors assembled a cohort of all 5-year CCS who were diagnosed before age 18 years and treated in an Ontario pediatric cancer center between 1987 and 2008. Patients were matched to population controls and linked to health administration databases. The authors calculated rates of mental health care visits (family physician, psychiatrist, emergency department, hospitalization) and the risk for a severe mental health event (emergency department, hospitalization, suicide). Outcomes were compared using recurrent event and survival analyses. RESULTS: Compared with 20,269 controls, 4117 CCS had a higher rate of mental health visits (adjusted relative rate [RR], 1.34; 95% confidence interval [CI], 1.12-1.52). Higher rates were associated with female gender (RR, 1.39; CI, 1.10-1.75; P = .006) and being diagnosed at ages 15 to 17.9 years (compared with ages 0-4 years: RR, 1.81; 95% CI, 1.17-2.80; P = .008). Cancer type, treatment intensity, and treatments targeting the central nervous system were not significant predictors. Survivors were at increased risk for a severe event compared with controls (adjusted hazard ratio, 1.13; 95% CI, 1.00 1.28; P = .045). CCS who were diagnosed with cancer at age 4 years or younger were at greatest risk: 16.3% (95% CI, 13.2%-19.8%) had experienced a severe event by age 28 years. CONCLUSIONS: CCS experienced higher rates of mental health visits and a greater risk for a severe event than the general population. Survivors of adolescent cancer have a higher rate of mental health visits overall, whereas survivors of cancer before age 4 years have a markedly elevated risk of severe events.

PMID- 29468666 TI - Eicosanoids, prostacyclin and cyclooxygenase in the cardiovascular system. AB - Eicosanoids represent a diverse family of lipid mediators with fundamental roles in physiology and disease. Within the eicosanoid superfamily are prostanoids, which are specifically derived from arachidonic acid by the enzyme cyclooxygenase (COX). COX has two isoforms; COX-1 and COX-2. COX-2 is the therapeutic target for the nonsteroidal anti-inflammatory drug (NSAID) class of pain medications. Of the prostanoids, prostacyclin, first discovered by Sir John Vane in 1976, remains amongst the best studied and retains an impressive pedigree as one of the fundamental cardiovascular protective pathways. Since this time, we have learnt much about how eicosanoids, COX enzymes and prostacyclin function in the cardiovascular system, knowledge that has allowed us, for example, to harness the power of prostacyclin as therapy to treat pulmonary arterial hypertension and peripheral vascular disease. However, there remain many unanswered questions in our basic understanding of the pathways, and how they can be used to improve human health. Perhaps, the most important and controversial outstanding question in the field remains; 'how do NSAIDs produce their much publicized cardiovascular side-effects?' This review summarizes the history, biology and cardiovascular function of key eicosanoids with particular focus on prostacyclin and other COX products and discusses how our knowledge of these pathways can applied in future drug discovery and be used to explain the cardiovascular side-effects of NSAIDs. PMID- 29468667 TI - Teachers' knowledge concerning dental trauma and its management in primary schools in Riyadh, Saudi Arabia. AB - OBJECTIVES: The main aim of this cross-sectional study was to assess knowledge concerning traumatic dental injuries and their management among primary schoolteachers in Riyadh, Saudi Arabia. The secondary objective was to evaluate the effect of gender, nationality, marital status, school type, geographical area, age group, level of education and years of experience on teachers' knowledge. METHODOLOGY: Data were collected, through a self-administered questionnaire, from both male and female teachers employed in public and private primary schools in the five geographical areas of Riyadh City. The total sample size was 1,520 teachers. Data were entered into the Statistical Package for the Social Sciences. Frequencies and percentages were calculated. An independent t test and a one-way analysis of variance (ANOVA) were used to calculate significance. RESULTS: The total score for the questions assessing knowledge was calculated out of 9, and the highest score was 7 with an average score of 2.85. Over half of the sampled participants stated that they did not know how to manage soft-tissue injuries. Regarding the management of fractured teeth, 38.8% believed that the fractured part is useless; and for the management of an avulsed permanent tooth, only 6.2% of the respondents selected the correct answer. For the question regarding suitable storage medium of an avulsed tooth, only 19.7% chose milk and 3.2% chose the injured person's saliva. Teachers between 41 and 50 years of age and those with longer years of experience had the highest level of knowledge. Teachers in the north area of Riyadh had a higher level of knowledge than teachers in other areas. CONCLUSION: There was a lack of knowledge among primary schoolteachers in Riyadh concerning traumatic dental injuries and their management. Statistically significant differences were found among geographical areas, age groups and years of experience; no statistically significant differences were found regarding gender, nationality, marital status, level of education and school type (public/private). PMID- 29468668 TI - Myelin oligodendrocyte glycoprotein and aquaporin-4 antibodies are highly specific in children with acquired demyelinating syndromes. AB - AIM: Our objectives were to evaluate the utility of measuring myelin oligodendrocyte glycoprotein (MOG) and aquaporin-4 (AQP4) antibodies (Ab) in clinical practice and describe their associated neurological phenotypes in children. METHOD: Between 2012 and 2017, 371 children with suspected acquired demyelinating syndromes (ADS) seen in three tertiary centres were tested for MOG Ab and AQP4-Ab. Medical notes were retrospectively reviewed, and clinical and demographic data compiled. Clinical phenotyping was performed blinded to the antibody results. RESULTS: After review, 237 of the 371 were diagnosed with ADS. Of these, 76 out of 237 (32.1%) were MOG-Ab positive and 14 out of 237 (5.9%) were AQP4-Ab positive. None were positive for both autoantibodies. All 134 patients with non-ADS were negative for MOG-Ab. MOG-Ab were identified in 45 out of 70 (64.3%) patients presenting with acute disseminated encephalomyelitis (ADEM) and in 24 out of 25 patients with relapsing ADEM. Thirty-six out of 75 (48%) MOG-Ab positive patients relapsed. Of the 33 children with neuromyelitis optic spectrum disorder, 14 were AQP4-Ab positive, 13 were MOG-Ab positive, and 6 were seronegative. Of the children with longitudinal samples, 8 out of 13 AQP4-Ab remained positive during the disease course compared to 35 out of 43 MOG-Ab (13/16 monophasic and 22/27 relapsing). INTERPRETATION: Myelin oligodendrocyte glycoprotein antibodies were identified in a third of children with ADS. Almost half of the MOG-Ab positive children relapsed and the majority of them remained antibody positive over 4-years follow-up. WHAT THIS PAPER ADDS: Myelin oligodendrocyte glycoprotein antibodies (MOG-Ab) are highly specific for acquired demyelinating syndromes (ADS). Myelin oligodendrocyte glycoprotein antibodies are not identified in children with peripheral demyelination or genetic leukodystrophies/hypomyelination. Up to 48% of MOG-Ab ADS paediatric patients relapse, higher than previously thought. Seroconversion to MOG-Ab negative status is infrequent; patients may test MOG-Ab positive at follow-up sampling even when asymptomatic. Myelin oligodendrocyte glycoprotein antibodies status should only be used in conjunction with the clinical information to guide maintenance therapy. PMID- 29468670 TI - Housing Interventions and the Chronic and Acute Risks of Family Homelessness: Experimental Evidence for Education. AB - This study considers risk associated with family homelessness for school functioning and experimental evidence on the effects of different housing interventions over time. Students in homeless families (N = 172; Mage = 7.31; SD = 4.15) were randomized to housing interventions that focus on acute risks (community-based rapid rehousing), chronic risks (permanent subsidy), or usual care (UC). A matched group of low-income, housed students served as an additional reference for effects on attendance, school mobility, and reading and math achievement across 4 years. Findings partially support the chronic-risk hypothesis that family homelessness interferes with achievement through its relation to deep poverty. Children randomly assigned to UC perform as well or better than children assigned to housing interventions in this municipality. PMID- 29468669 TI - Racial/Ethnic Differential Effects of Medicaid Expansion on Health Care Access. AB - OBJECTIVE: To assess racial/ethnic differential impacts of the ACA's Medicaid expansion on low-income, nonelderly adults' access to primary care. DATA SOURCES: Behavioral Risk Factor Surveillance System, State Physicians Workforce Data Book, and Bureau of Labor Statistics, in 2013 and 2015. STUDY DESIGN: Quasi experimental design with difference-in-differences analyses. Outcomes included health insurance coverage, having personal doctor(s), being unable to see doctors because of cost, and receiving a flu shot. We tested racial/ethnic differential impacts using the "Seemingly unrelated estimation" method. Multiple imputations and survey weights were used. DATA COLLECTION/EXTRACTION METHODS: Low-income, nonelderly adults were identified based on age, household income, and family size. PRINCIPAL FINDINGS: Among the low-income, nonelderly adults, Medicaid expansion was associated with statistically significant gains in health insurance coverage, having personal doctors, and affordability. Hispanics got the fewest benefits, which significantly widened racial/ethnic disparities for the Hispanic group. Racial/ethnic disparity in having personal doctors narrowed for non Hispanic black and non-Hispanic others, although not statistically significant. CONCLUSION: Medicaid expansion improved access to primary care, but it had differential effects among racial/ethnic groups resulting in mixed effects on disparities. Further research is necessary to develop tailored policy tools for racial/ethnic groups. PMID- 29468671 TI - A Practical Grid-Based Alternative Method to Advective Particle Tracking. AB - Advective particle tracking is a conventional groundwater modeling technique that is widely used as a screening tool but lacks robustness as a reliable method for general applications. In this work, we investigate the suitability of industry standard, finite-difference, grid-based methods as an alternative to the conventional particle-tracking approach. The presented method is classified as a particular case of the more general forward- or backward-in-time advective dispersive probabilistic transport approaches. The proposed method is used as a powerful screening tool to accurately delineate and visualize capture zones around abstraction wells or outflow boundaries, the swept zones formed by injection wells or inflow boundaries, and the partitions associated with injection-pumping well doublets or inflowing-outflowing boundary pairs. Moreover, we show that the forward or backward travel times and residence time distributions are robustly simulated and visualized on the computational grid with little computational effort. Two examples are given to illustrate the key advantages of this method in groundwater applications. The first example considers a synthetic pump-and-treat remediation system in an irregularly layered aquifer. The second example involves four doublet wells operating for heat extraction in the Dogger geothermal reservoir in the Paris Basin, a leading European scale project. The presented approach is far more comprehensive as a screening tool than the conventional method, providing a natural intermediate step before processing the more general time-dependent advective-dispersive simulations. PMID- 29468672 TI - CaV 3.2 drives sustained burst-firing, which is critical for absence seizure propagation in reticular thalamic neurons. AB - OBJECTIVE: Genetic alterations have been identified in the CACNA1H gene, encoding the CaV 3.2 T-type calcium channel in patients with absence epilepsy, yet the precise mechanisms relating to seizure propagation and spike-wave-discharge (SWD) pacemaking remain unknown. Neurons of the thalamic reticular nucleus (TRN) express high levels of CaV 3.2 calcium channels, and we investigated whether a gain-of-function mutation in the Cacna1h gene in Genetic Absence Epilepsy Rats from Strasbourg (GAERS) contributes to seizure propagation and pacemaking in the TRN. METHODS: Pathophysiological contributions of CaV 3.2 calcium channels to burst firing and absence seizures were assessed in vitro using acute brain slice electrophysiology and quantitative real-time polymerase chain reaction (PCR) and in vivo using free-moving electrocorticography recordings. RESULTS: TRN neurons from GAERS display sustained oscillatory burst-firing that is both age- and frequency-dependent, occurring only in the frequencies overlapping with GAERS SWDs and correlating with the expression of a CaV 3.2 mutation-sensitive splice variant. In vivo knock-down of CaV 3.2 using direct thalamic injection of lipid nanoparticles containing CaV 3.2 dicer small interfering (Dsi) RNA normalized TRN burst-firing, and in free-moving GAERS significantly shortened seizures. SIGNIFICANCE: This supports a role for TRN CaV 3.2 T-type channels in propagating thalamocortical network seizures and setting the pacemaking frequency of SWDs. PMID- 29468673 TI - Chronic pain prevalence and associated factors in adolescents with and without physical disabilities. AB - AIM: Adolescents with physical disabilities may have co-occurring chronic pain, but the prevalence and specific associated factors are unknown. The aims of this study were to determine (1) the prevalence of chronic pain in adolescents with physical disabilities and (2) whether known correlates of chronic pain in the general population are also present in young people both with physical disability and with chronic pain relative to peers. METHOD: We conducted a secondary analysis of cross-sectional nationally representative data from the National Longitudinal Study of Adolescent to Adult Health. Multivariate linear regression analysis was used to identify demographic and psychosocial factors associated with chronic pain. RESULTS: A total of 989 (4.3%) adolescents reported physical disabilities. They had a significantly higher rate of pain (27.2%) compared with able-bodied peers (15.6%, chi2 =86.3550, p<0.001). There was no significant interaction between physical disability status and chronic pain in relation to depressive symptoms, anxiety, or insomnia. INTERPRETATION: Adolescents with physical disabilities experience chronic pain at a significantly higher rate than able-bodied peers, but the comorbidity of physical disability and chronic pain is not related to depression, anxiety, or insomnia. Evaluation of chronic pain and tailored pain interventions need to be developed for this population. WHAT THIS PAPER ADDS: Chronic pain and its correlates are important problems for adolescents with physical disabilities. These adolescents present with higher rates of chronic pain than other young people. Chronic pain is associated with increased levels of depressive symptoms, anxiety, and insomnia regardless of disability status. PMID- 29468674 TI - Mental health of long-term survivors of childhood and young adult cancer: A systematic review. AB - Childhood cancer is increasing in prevalence whilst survival rates are improving. The prevalence of adult survivors of childhood cancer is consequently increasing. Many survivors suffer long-term consequences of their cancer treatment. Whilst many of these are well documented, relatively little is known about the mental health of survivors of childhood cancer. This article aimed to describe the prevalence and spectrum of mental health problems found in adult survivors of childhood cancer using a systematic review methodology. Our review included 67 articles, describing a number of problems, including depression, anxiety, behavioural problems and drug misuse. Factors increasing the likelihood of mental health problems included treatment with high-dose anthracyclines, cranial irradiation, diagnoses of sarcoma or central nervous system tumours and ongoing physical ill health. There were numerous limitations to the studies we found, including use of siblings of survivors as a control group, self-report methodology and lack of indications for prescriptions when prescribing data were used. This review has identified many mental health problems experienced by survivors of childhood cancer; however, the exact incidence, prevalence and risk factors for their development remain unclear. Further work to identify childhood cancer patients who are at risk of developing late mental health morbidity is essential. PMID- 29468675 TI - Market Competition and Health Outcomes in Hemodialysis. AB - OBJECTIVE: To examine whether market competition is associated with improved health outcomes in hemodialysis. DATA SOURCES: Secondary analysis of data from a national dialysis registry between 2001 and 2011. STUDY DESIGN: We conducted one- and two-part linear regression models, using each hospital service area (HSA) as its own control, to examine the independent associations among market concentration and health outcomes. DATA COLLECTION: We selected cohorts of patients receiving in-center hemodialysis in the United States at the start of each calendar year. We used information about dialysis facility ownership and the location where patients received dialysis to measure an index of market concentration-the Hirschman-Herfindahl Index (HHI)-for HSA and year, which ranges from near zero (perfect competition) to one (monopoly). PRINCIPAL FINDINGS: An average reduction in HHI by 0.2 (one standard deviation in 2011) was associated with 2.9 fewer hospitalizations per 100 patient-years (95 percent CI, 0.4 to 5.4). If these findings were generalized to the entire in-center hemodialysis population, this would translate to 8,100 (95 percent CI 1,200 to 15,000) fewer hospitalizations in 2011. There was no association between change in market competition and mortality. CONCLUSIONS: Market competition in dialysis may lead to improved health outcomes.

PMID- 29468677 TI - Determination of kQmsr,Q0fmsr,fref factors for ion chambers used in the calibration of Leksell Gamma Knife Perfexion model using EGSnrc and PENELOPE Monte Carlo codes. AB - PURPOSE: To calculate the kQmsr,Q0fmsr,fref factors for nine common ionization chamber types following the small fields dosimetry formalism for the calibration of the Leksell Gamma Knife(r) (LGK) PerfexionTM using Monte Carlo simulation. This study also provides the first independent comparison of EGSnrc and PENELOPE for the calculation of kQmsr,Q0fmsr,fref correction factors and proposes a practical method to predict these factors based on chamber type, chamber orientation and phantom electron density. METHODS: The ionization chambers are modeled using the EGSnrc and PENELOPE Monte Carlo codes based on the blueprints provided by the manufacturers. The chambers are placed in a half-sphere water phantom and five spherical phantoms made of liquid water, solid water, ABS, polystyrene, and PMMA, respectively. Dose averaged over the air cavity of the chambers and a small water volume are calculated using EGSnrc and PENELOPE Monte Carlo codes for both conventional and machine specific reference (msr) setups. Using the calculated dose ratio, the kQmsr,Q0fmsr,fref factor is determined for all phantom materials and two possible orientations of chamber. The calculated kQmsr,Q0fmsr,fref factors are compared to a previous Monte Carlo study. A relationship between the kQmsr,Q0fmsr,fref factor and the electron density of the phantom material is derived to predict the kQmsr,Q0fmsr,fref factor for any phantom material type. Applying the calculated kQmsr,Q0fmsr,fref factors to the measured dose rate of a recent round robin study improves consistency of reference dosimetry of the Leksell Gamma Knife(r) (LGK) PerfexionTM . RESULTS: Agreement within uncertainty is observed between kQmsr,Q0fmsr,fref values determined in this study and the previous PEGASOS/PENELOPE study in a liquid water phantom. The difference between kQmsr,Q0fmsr,fref values in parallel and perpendicular detector orientations is most significant for the PTW 31010 (1.8%) chamber. The percentage root-mean-square (%RMS) deviation between EGSnrc and PENELOPE calculated kQmsr,Q0fmsr,fref values for Exradin-A1SL, A14 and A14SL chambers studies in this work was found to be 0.4%. The kQmsr,Q0fmsr,fref values increase linearly with electron density of the phantom material for all chamber types mainly due to the linear dependency of photon energy fluence ratios on electron density. The average percentage difference between the calculated and predicted kQmsr,Q0fmsr,fref values using two methods is found to be 0.15% and 0.16%. Previously measured dose rates corrected with the kQmsr,Q0fmsr,fref values determined in this work leads to absorbed dose values consistent to within 0.8%. CONCLUSIONS: The calculated kQmsr,Q0fmsr,fref values in this work will enable users to apply the appropriate correction for their own specific phantom material only knowing the electron density of the phantom material. PMID- 29468678 TI - Image guidance doses delivered during radiotherapy: Quantification, management, and reduction: Report of the AAPM Therapy Physics Committee Task Group 180. AB - BACKGROUND: With radiotherapy having entered the era of image guidance, or image guided radiation therapy (IGRT), imaging procedures are routinely performed for patient positioning and target localization. The imaging dose delivered may result in excessive dose to sensitive organs and potentially increase the chance of secondary cancers and, therefore, needs to be managed. AIMS: This task group was charged with: a) providing an overview on imaging dose, including megavoltage electronic portal imaging (MV EPI), kilovoltage digital radiography (kV DR), Tomotherapy MV-CT, megavoltage cone-beam CT (MV-CBCT) and kilovoltage cone-beam CT (kV-CBCT), and b) providing general guidelines for commissioning dose calculation methods and managing imaging dose to patients. MATERIALS & METHODS: We briefly review the dose to radiotherapy (RT) patients resulting from different image guidance procedures and list typical organ doses resulting from MV and kV image acquisition procedures. RESULTS: We provide recommendations for managing the imaging dose, including different methods for its calculation, and techniques for reducing it. The recommended threshold beyond which imaging dose should be considered in the treatment planning process is 5% of the therapeutic target dose. DISCUSSION: Although the imaging dose resulting from current kV acquisition procedures is generally below this threshold, the ALARA principle should always be applied in practice. Medical physicists should make radiation oncologists aware of the imaging doses delivered to patients under their care. CONCLUSION: Balancing ALARA with the requirement for effective target localization requires that imaging dose be managed based on the consideration of weighing risks and benefits to the patient. PMID- 29468679 TI - Remote treatment of sleep-related trichotillomania and trichophagia. AB - We used a biobehavioral treatment consisting of melatonin and a standardized bed and wake time to decrease one girl's head and mouth touches associated with sleep related trichotillomania and trichophagia. We remotely coached the girl's caregiver to implement all procedures and monitored response to treatment using a DropCam Pro video camera equipped with night-vision capabilities. Head and mouth touches decreased, and her sleep pattern improved with the combination of treatment strategies. We discuss our use of a novel mode of service delivery to treat sleep-related problem behavior. PMID- 29468680 TI - Proinflammatory role of blister fluid-derived exosomes in bullous pemphigoid. AB - Bullous pemphigoid is an autoimmune inflammatory disorder characterized by the presence of autoantibodies against bullous pemphigoid autoantigens, leading to dermal-epidermal separation with consequent blister formation. However, whether and how the components of blister fluid exacerbate the progression of bullous pemphigoid is unclear. Exosomes are nanometre-sized vesicles released from cells into the body fluid, where they can transmit signals throughout the body. In the present study, we isolated and characterized exosomes from blister fluids of patients with bullous pemphigoid, evaluated their proinflammatory role, and identified the underlying molecular mechanisms. We found that exosomes isolated from blister fluids of patients with bullous pemphigoid showed the expected size and expressed the marker proteins CD63, CD81, and CD9. Additionally, blister fluid-derived exosomes were internalized by human primary keratinocytes, inducing the production of critical inflammatory cytokines and chemokines. Western blotting analysis showed robust and rapid activation of the extracellular signal regulated kinase 1/2 and signal transducer and activator of transcription 3 signalling pathways in human primary keratinocytes after stimulation with blister fluid-derived exosomes. We also found that blister fluid-derived exosomes indirectly induced neutrophil trafficking by upregulating C-X-C motif chemokine ligand 8 in vitro. Furthermore, CD63 was localized mostly to keratinocytes and infiltrative granulocytes in skin lesions, suggesting that these cells were the possible sources of exosomes in blister fluid. Using mass spectrometry, we analysed the proteomes of blister fluid-derived exosomes and identified a variety of proteins implicated in inflammatory and immune responses. Together, our findings provide strong evidence that blister fluid-derived exosomes are involved in the local autoinflammatory responses of the skin associated with bullous pemphigoid.

PMID- 29468681 TI - Spatiotemporal distribution of small ubiquitin-like modifiers during human placental development and in response to oxidative and inflammatory stress. AB - KEY POINTS: The post-translational modification of target proteins by SUMOylation occurs in response to stressful stimuli in a variety of organ systems. Small ubiquitin-like modifier (SUMO) isoforms 1-4 have recently been identified in the human placenta, and are upregulated in the major obstetrical complication of pre eclampsia. This is the first study to characterize the spatiotemporal distribution of SUMO isoforms and their targets during placental development across gestation and in response to stress induced by pre-eclampsia and chorioamnionitis. Keratins were identified as major targets of placental SUMOylation. The interaction with SUMOs and cytoskeletal filaments provides evidence for SUMOylation possibly contributing to underlying dysfunctional trophoblast turnover, which is a hallmark feature of pre-eclampsia. Further understanding the role of individual SUMO isoforms and SUMOylation underlying placental dysfunction may provide a target for a novel therapeutic candidate as an approach for treating pre-eclampsia complicated with placental pathology. ABSTRACT: SUMOylation is a dynamic, reversible post-translational modification that regulates cellular protein stability and localization. SUMOylation occurs in response to various stressors, including hypoxia and inflammation, features common in the obstetrical condition of pre-eclampsia. SUMO isoforms 1-4 have recently been identified in the human placenta, but less is known about their role in response to pre-eclamptic stress. We hypothesized that SUMOylation components have a unique spatiotemporal distribution during placental development and that their subcellular localization can be further modulated by extra cellular stressors. Placental SUMO expression was examined across gestation. First-trimester human placental explants and JAR cells were subjected to hypoxia or TNF-alpha cytokine, and subcellular translocation of SUMOs was monitored. SUMOylation target proteins were elucidated using mass spectrometry and proximity ligation assay. Placental SUMO-1 and SUMO-4 were restricted to villous cytotrophoblast cells in first trimester and syncytium by term, while SUMO-2/3 staining was evenly distributed throughout the trophoblast across gestation. In placental villous explants, oxidative stress induced hyperSUMOylation of SUMO-1 and SUMO-4 in the syncytial cytoplasm, whereas SUMO-2/3 nuclear expression increased. Oxidative stress also upregulated cytoplasmic SUMO-1 and SUMO-4 protein expression (P < 0.05), similar to pre-eclamptic placentas. Keratins were identified as major targets of placental SUMOylation. Oxidative stress increased the cytokeratin-7 to SUMO-1 and SUMO-4 interactions, while inflammatory stress increased its interaction with SUMO-2/3. Overall, SUMOs display a unique spatiotemporal distribution in normal human placental development. Our data indicate SUMOylation in pre-eclampsia, which may impair the stability of cytoskeleton filaments and thus promote trophoblast shedding into the maternal circulation in this condition.

AB - OBJECTIVE: To determine preferences for companionship during labor and to identify associated factors. METHODS: The present prospective cross-sectional survey was conducted at a university teaching hospital in Nigeria between September 1, 2011, and February 28, 2012. Participants included women who underwent the first stage of labor and delivery at the facility, male partners, and healthcare workers from the maternity unit. Data were collected using a pretested questionnaire. RESULTS: There were 226 parturients, 158 male partners, and 69 healthcare workers included in the final analysis; in all, 50 (22.1%) parturients and 37 (23.4%) male partners approved of companionship during labor, whereas 62 (90%) healthcare workers supported it. Among those who approved, a parturient's male partner was stated to be the preferred companion by 33 (66%) parturients, 32 (86%) male partners, and 58 (94%) healthcare workers. The perception of conduciveness of the labor ward for companionship was associated with approving of companionship among both the parturients (adjusted odds ratio [aOR] 2.74) and male partners (aOR 15.79). Previous home delivery (aOR 31.43) and companionship during a previous delivery (aOR 23.00) were also associated with approval. CONCLUSION: Most couples had negative attitudes toward companionship during labor. Intensive education programs and restructuring of facilities could enable Nigerian labor wards to improve the delivery experience for both parturients and their male partners.

AB - Morphometrics, the assignment of quantities to biological shapes, is a powerful tool to address taxonomic, evolutionary, functional and developmental questions. We propose a novel method for shape quantification of complex modular architecture in thalloid plants, whose extremely reduced morphologies, combined with the lack of a formal framework for thallus description, have long rendered taxonomic and evolutionary studies extremely challenging. Using graph theory, thalli are described as hierarchical series of nodes and edges, allowing for accurate, homologous and repeatable measurements of widths, lengths and angles. The computer program MorphoSnake was developed to extract the skeleton and contours of a thallus and automatically acquire, at each level of organization, width, length, angle and sinuosity measurements. Through the quantification of leaf architecture in Hymenophyllum ferns (Polypodiopsida) and a fully worked example of integrative taxonomy in the taxonomically challenging thalloid liverwort genus Riccardia, we show that MorphoSnake is applicable to all ramified plants. This new possibility of acquiring large numbers of quantitative traits in plants with complex modular architectures opens new perspectives of applications, from the development of rapid species identification tools to evolutionary analyses of adaptive plasticity.

AB - Medication control and doping control have been established in horse racing to ensure the integrity of the sport and the welfare of the horses. This ensures that horses do not compete under the influence of any drugs, including omeprazole, a therapeutic medication used to treat equine gastric ulcer syndrome. In this study, pharmacokinetic data were produced in equine plasma and urine following an oral administration of 4 mg/kg of generic buffered formulation of omeprazole to six Thoroughbred horses in five daily doses to determine an appropriate screening limit and detection time in equine plasma and to assess whether the current detection time of 72 hr in equine urine would be applicable when an alternative omeprazole product is administered. Cmax of 436-2,432 ng/ml and AUC0-tau of 1,476-4,371 ng hr ml-1 were obtained for plasma and indicated, in conjunction with other published oral omeprazole studies, that an appropriate plasma screening limit would be 500 pg/ml with a detection time of 48 hr. Urine analysis showed that omeprazole could be detected for up to 25 hr above the previously established urine screening limit of 500 pg/ml and thus indicated that the detection time advice could be potentially reduced from 72 to 48 hr to allow more comprehensive treatment of gastric lesions. PMID- 29468685 TI - A rapid cycle method for local adaptation of an obstetric emergencies training program. AB - OBJECTIVE: To describe the adaptation of an obstetric emergencies training program to align with local clinical practice. METHODS: A feasibility study was conducted to investigate the potential implementation of the PRactical Obstetric Multi-Professional Training (PROMPT) program at eight urban tertiary hospitals in the Philippines. Multi-professional teams attended a 2-day course on September 23 and 24, 2015, that comprised a demonstration PROMPT course (day 1) and a Train the-Trainers session (day 2). During a facilitated adaptation session, each team reviewed the PROMPT algorithms for eclampsia, severe pre-eclampsia, postpartum hemorrhage and sepsis. The teams marked steps concordant with local practice and identified differences with local practice. Suggested amendments were reviewed by the PROMPT project team, using clinical guidelines to support any adaptations. RESULTS: The PROMPT algorithm for initial management of eclampsia was used as an exemplar. Five of the nine management steps were concordant with local practice: support; airway; breathing; circulation; and control seizures. Amendments were successfully implemented for the following steps: call for help; magnesium sulfate loading dose; and magnesium sulfate maintenance dose. CONCLUSION: Rapid and efficient adaptation of PROMPT training materials for use in the Philippines was possible using a facilitated and focused approach, utilizing the expertise of a representative mix of local healthcare professionals and evidence-based guidelines. PMID- 29468686 TI - Token reinforcement: Translational research and application. AB - The present paper provides an integrative review of research on token reinforcement systems, organized in relation to basic behavioral functions and economic variables. This type of functional taxonomy provides a useful way to organize the literature, bringing order to a wide range of findings across species and settings, and revealing gaps in the research and areas especially ripe for analysis and application. Unlike standard translational research, based on a unidirectional model in which the analysis moves from laboratory to the applied realm, work in the area of token systems is best served by a bidirectional interplay between laboratory and applied research, where applied questions inspire research on basic mechanisms. When based on and contributing to an analysis, applied research on token economies can be on the leading edge of theoretical advances, helping set the scientific research agenda. PMID- 29468688 TI - Polymorphisms of cytochrome P450 2B6 (CYP2B6) in cynomolgus and rhesus macaques. AB - BACKGROUND: Cytochrome P450 2B6 (CYP2B6) is an important drug-metabolizing enzyme and is expressed in liver. Although human CYP2B6 variants account for variable enzyme properties among individuals and populations, CYP2B6 genetic variants have not been investigated in cynomolgus macaques, widely used in drug metabolism studies. METHODS: CYP2B6 was resequenced in 120 cynomolgus macaques and 23 rhesus macaques by direct sequencing. RESULTS: Twenty-three non-synonymous variants were found, of which 12 and 3 were unique to cynomolgus macaques and rhesus macaques, respectively. By functional characterization using the 14 variant proteins, 8 variants (V114I, R253C, M435I, V459M, L465P, C475S, R487C, and R487H) showed different rate (>1.5-fold) of testosterone 16beta-hydroxylation to wild type. However, the four variants (M435I, L465P, C475S, and R487H) were analyzed in liver microsomes, and the catalytic rates were not substantially different from wild type. CONCLUSIONS: Macaque CYP2B6 was polymorphic, and the genotype could partly account for variable enzyme activities of macaque CYP2B6.

AB - Susceptibility to the root-knot nematode Meloidogyne incognita in plants is thought to be a complex trait based on multiple genes involved in cell differentiation, growth and defence. Previous genetic analyses of susceptibility to M. incognita have mainly focused on segregating dominant resistance genes in crops. It is not known if plants harbour significant genetic variation in susceptibility to M. incognita independent of dominant resistance. To study the genetic architecture of susceptibility to M. incognita, we analysed nematode reproduction on a highly diverse set of 340 natural inbred lines of Arabidopsis thaliana with genome-wide association mapping. We observed a surprisingly large variation in nematode reproduction among these lines. Genome-wide association mapping revealed four quantitative trait loci (QTLs) located on chromosomes 1 and 5 of A. thaliana significantly associated with reproductive success of M. incognita, none of which harbours typical resistance gene homologues. Mutant analysis of three genes located in two QTLs showed that the transcription factor BRASSINAZOLE RESISTANT1 and an F-box family protein may function as (co )regulators of susceptibility to M. incognita in Arabidopsis. Our data suggest that breeding for loss-of-susceptibility, based on allelic variants critically involved in nematode feeding, could be used to make crops more resilient to root knot nematodes.

AB - In this article, we comment on the significant contributions to science and to clinical practice made by Floccia et al.'s study of over 400 bilingual 2-year-old children. To science, this work contributes new findings on the linguistic factors that make some pairs of languages easier to learn than others and rich data on the environmental factors that influence bilingual development. Their results provide clues to the nature of the language learning process. To clinical practice, Floccia et al. contribute a new instrument for the diagnosis of risk for language impairment in bilingual children and a new method for the development of assessment instruments more generally. The experience-adjusted approach to norming that they illustrate here provides an example for others to follow. Their method holds promise for test development in many domains where the goal is to assess children's internal capacity but the evidence that is available in children's achievement is systematically influenced by environmental factors. PMID- 29468690 TI - Lost in diversity: the interactions between soil-borne fungi, biodiversity and plant productivity. AB - There is consensus that plant species richness enhances plant productivity within natural grasslands, but the underlying drivers remain debated. Recently, differential accumulation of soil-borne fungal pathogens across the plant diversity gradient has been proposed as a cause of this pattern. However, the below-ground environment has generally been treated as a 'black box' in biodiversity experiments, leaving these fungi unidentified. Using next generation sequencing and pathogenicity assays, we analysed the community composition of root-associated fungi from a biodiversity experiment to examine if evidence exists for host specificity and negative density dependence in the interplay between soil-borne fungi, plant diversity and productivity. Plant species were colonised by distinct (pathogenic) fungal communities and isolated fungal species showed negative, species-specific effects on plant growth. Moreover, 57% of the pathogenic fungal operational taxonomic units (OTUs) recorded in plant monocultures were not detected in eight plant species plots, suggesting a loss of pathogenic OTUs with plant diversity. Our work provides strong evidence for host specificity and negative density-dependent effects of root-associated fungi on plant species in grasslands. Our work substantiates the hypothesis that fungal root pathogens are an important driver of biodiversity-ecosystem functioning relationships. PMID- 29468693 TI - II: METHODS. PMID- 29468694 TI - IV: RESULTS FOR STUDIES 2 AND 3: THE UKBTAT MODEL AND ITS APPLICATION TO NONTARGET ADDITIONAL LANGUAGE LEARNERS. PMID- 29468696 TI - I: INTRODUCTION. AB - The majority of the world's children grow up learning two or more languages. The study of early bilingualism is central to current psycholinguistics, offering insights into issues such as transfer and interference in development. From an applied perspective, it poses a universal challenge to language assessment practices throughout childhood, as typically developing bilingual children usually underperform relative to monolingual norms when assessed in one language only. We measured vocabulary with Communicative Development Inventories for 372 24-month-old toddlers learning British English and one Additional Language out of a diverse set of 13 (Bengali, Cantonese, Dutch, French, German, Greek, Hindi Urdu, Italian, Mandarin, Polish, Portuguese, Spanish, and Welsh). We furthered theoretical understanding of bilingual development by showing, for the first time, that linguistic distance between the child's two languages predicts vocabulary outcome, with phonological overlap related to expressive vocabulary, and word order typology and morphological complexity related to receptive vocabulary, in the Additional Language. Our study also has crucial clinical implications: we have developed the first bilingual norms for expressive and receptive vocabulary for 24-month-olds learning British English and an Additional Language. These norms were derived from factors identified as uniquely predicting CDI vocabulary measures: the relative amount of English versus the Additional Language in child-directed input and parental overheard speech, and infant gender. The resulting UKBTAT tool was able to accurately predict the English vocabulary of an additional group of 58 bilinguals learning an Additional Language outside our target range. This offers a pragmatic method for the assessment of children in the majority language when no tool exists in the Additional Language. Our findings also suggest that the effect of linguistic distance might extend beyond bilinguals' acquisition of early vocabulary to encompass broader cognitive processes, and could constitute a key factor in the study of the debated bilingual advantage.

PMID- 29468698 TI - Systematic review: non A-E, seronegative or indeterminate hepatitis; what is this deadly disease? AB - BACKGROUND: A significant proportion of cases of acute liver failure (ALF) do not have an identifiable cause; so called "non A-E," "non A, non B, non C," "seronegative" or "indeterminate" hepatitis. However, this entity is clinically not well described. AIM: To collate the known incidence and outcomes in indeterminate hepatitis. This systematic review sought to identify potential aetiologies that ought to be considered, and identify likely future objectives in classification and treatment strategies for indeterminate hepatitis. METHODS: Literature review to determine aetiological factors, prevalence and outcomes relating to indeterminate hepatitis. RESULTS: There is significant heterogeneity within the reported cases of indeterminate hepatitis in the literature. Some of the potential infective aetiologies which are reviewed here include: parvovirus B19 (PVB19), herpes simplex virus (HSV), Toga-Like Virus and the Annelloviridae (including SEN-V). Interestingly, this condition predominately affects middle aged women, with subacute progression of the liver failure. In addition, the prognosis of indeterminate hepatitis is poor, with reduced spontaneous survival compared with other causes of acute liver failure and increased need for emergency liver transplantation. CONCLUSIONS: Whilst various pathological processes have been implicated in the development of indeterminate hepatitis, the specific cause remains elusive. There is an urgent need for general consensus on a specific definition and exclusion of confounding aetiologies with coordinated multicentre investigation of this rare condition to identify aetiology and develop therapies to reduce the significant mortality and need for emergency liver transplantation associated with this condition.

AB - The above article from Medical Physics, published online on 22 February 2018 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the authors, the journal Editor in Chief and John Wiley & Sons Ltd. The retraction has been agreed following an investigation carried out by the editors due to major overlap with a previously published article: British Journal of Ophthalmology (BJO) (Sandhu HS, Eladawi N, Elmogy M, et al Automated diabetic retinopathy detection using optical coherence tomography angiography: a pilot study, British Journal of Ophthalmology Published Online First: 23 January 2018. doi:10.1136/bjophthalmol-2017-311489. PMID- 29468700 TI - Cancer cells govern miR-2909 exosomal recruitment through its 3'-end post transcriptional modification. AB - It is widely believed that selective packaging of nucleic acids, especially microRNAs, into exosomes secreted by the cancer cells not only ensures their growth and survival but also helps in the escape from immune surveillance. Keeping in view the fact that human cellular miR-2909 has emerged to regulate genes involved in oncogenesis and immunity, the present study was addressed to reveal the nature of miR-2909 expression within cancer cells of different tissue origin and its incorporation into exosomes secreted by these cells. Post transcriptional modification, especially 3'-end adenylation and uridylation of miR-2909, exerts opposing effects that may contribute to direct its sorting into exosomes secreted by cancer cells. Our study also revealed that selective partitioning of adenosine kinase, between cancer cells and their secreted exosomes, may be responsible for the nature of post-transcriptional modification of miR-2909 observed within these cells. PMID- 29468701 TI - Randomised clinical trial: efficacy, safety and dosage of adjunctive allopurinol in azathioprine/mercaptopurine nonresponders (AAA Study). AB - BACKGROUND: Thiopurine hypermethylation towards 6-methylmercaptopurine (6MMP) instead of 6-thioguanine nucleotides (6TGN) is associated with inefficacy in patients with IBD. Allopurinol reverses such hypermethylation. AIMS: To prospectively determine efficacy of allopurinol-thiopurine combination and to compare 2 doses of allopurinol. DESIGN: In a multicentre, double-blind trial, patients with clinically active or steroid-dependent IBD and thiopurine shunting were randomised to 50 or 100 mg/d allopurinol and 25% of their screening thiopurine dose, which was subsequently optimised, aiming for 6TGN of 260-500 pmol/8x108 RBCs. The primary endpoint was steroid-free clinical remission at 24 weeks. RESULTS: Of 73 patients, 39 (53% [95% CI 42-65]) achieved steroid-free remission, (54% with 50 mg/d and 53% with 100 mg/d). 81% were able to discontinue steroids. Therapeutic 6TGN levels were achieved in both groups. Final thiopurine doses were lower with 100 mg/d allopurinol (P < 0.005). 6MMP: 6TGN ratio decreased from mean 64 to 4 (P < 0.001), being higher with 50 mg/d (6 +/- 1.83) than for 100 mg/d ([1 +/- 0.16], P = 0.003). Three patients on 50 mg/d failed to sustain low ratios at 24 weeks. Toxicity was minimal; three patients on 50 mg/d allopurinol developed transient leukopenia. Alanine aminotransferase concentrations decreased (P < 0.001) similarly in both arms. Faecal calprotectin levels at study end were lower in patients who achieved the primary endpoint (median 171 [85-541] vs 821[110-5892] ug/g, P = 0.03). CONCLUSIONS: Low-dose allopurinol-thiopurine combination safely reverses shunting and optimises 6TGN with associated improvement in disease activity. 100 mg/d allopurinol is preferable due to greater metabolite profile stability and lower thiopurine dose without additional toxicity. PMID- 29468702 TI - Identifying optimal dosage regimes under safety constraints: An application to long term opioid treatment of chronic pain. AB - There is growing interest and investment in precision medicine as a means to provide the best possible health care. A treatment regime formalizes precision medicine as a sequence of decision rules, one per clinical intervention period, that specify if, when and how current treatment should be adjusted in response to a patient's evolving health status. It is standard to define a regime as optimal if, when applied to a population of interest, it maximizes the mean of some desirable clinical outcome, such as efficacy. However, in many clinical settings, a high-quality treatment regime must balance multiple competing outcomes; eg, when a high dose is associated with substantial symptom reduction but a greater risk of an adverse event. We consider the problem of estimating the most efficacious treatment regime subject to constraints on the risk of adverse events. We combine nonparametric Q-learning with policy-search to estimate a high quality yet parsimonious treatment regime. This estimator applies to both observational and randomized data, as well as settings with variable, outcome dependent follow-up, mixed treatment types, and multiple time points. This work is motivated by and framed in the context of dosing for chronic pain; however, the proposed framework can be applied generally to estimate a treatment regime which maximizes the mean of one primary outcome subject to constraints on one or more secondary outcomes. We illustrate the proposed method using data pooled from 5 open-label flexible dosing clinical trials for chronic pain. PMID- 29468703 TI - Individual differences in social control: Who 'speaks up' when witnessing uncivil, discriminatory, and immoral behaviours? AB - This research examined the personality characteristics of individuals who 'speak up' and confront perpetrators of norm transgressions. We tested whether those who intervene tend to be 'bitter complainers' or 'well-adjusted leaders'. In four studies (total N = 1,003), we measured several individual differences that are directly implicated by at least one of the two concepts. We also presented participants with uncivil, discriminatory, and immoral behaviours and asked them how likely they would be to intervene if they were to witness each of these behaviours as a bystander. The results confirmed the well-adjusted leader hypothesis: Participants' self-reported tendency to confront perpetrators correlated positively with altruism, extraversion, social responsibility, acceptance by peers, independent self-construal, emotion regulation, persistence, self-directedness, age, occupation, and monthly salary, but not with aggressiveness or low self-esteem. Individuals who confront prejudice also speak up against other immoral and uncivil behaviours. We discuss the implications of these findings for the perpetuation and change of social norms.

AB - Lichen aureus is a rare, chronic, persistent purpuric dermatosis clinically characterized by striking yellow- to bronze-colored lesions. Histologically, lichen aureus differs from other pigmented purpuric dermatoses in containing dense, band-like infiltrates closely associated with the epidermis. This report describes 2 patients with lichen aureus, a 20-year-old woman with a lesion on her right arm and a 51-year-old man with a lesion on the right side of his groin. Skin biopsy specimens revealed almost identical findings in both patients, including dense band-like infiltrates containing lymphocytes, histiocytes with hemosiderin deposits scattered extravasated red blood cells and nerve alterations at the dermo-epidermal interface. The nerves within the lesions were filled with granules, which stained positive with antibody to microtubule-associated protein 1A/1B-light chain 3, suggesting autophagy within the nerves. These altered nerves were present only in areas of band-like dermal lymphocytic infiltration. Electron microscopy of the lesions showed the accumulation of autophagosomes in Schwann cells. PMID- 29468705 TI - Low risk of hepatotoxicity from rifampicin when used for cholestatic pruritus: a cross-disease cohort study. AB - BACKGROUND: The use of rifampicin for cholestatic pruritus is accompanied by concerns over safety, but the availability of real-world prescribing data is relatively limited. AIM: We sought to describe the rate and characteristics of rifampicin-induced hepatitis in a mixed aetiology cohort of patients with established liver disease and cholestatic pruritus. METHODS: Retrospective review of records for out-patients commenced on rifampicin for pruritus 2012-2016 inclusive. Rifampicin-induced hepatitis was recorded where alanine aminotransferase activity (ALT) increased to both >=5 * baseline and >=5 * upper limit of normal (ULN), or to both >=3 * baseline and >=3 * ULN with concurrent elevation in serum bilirubin to >=2 * baseline and >=2 * ULN, in addition to a Roussel-Uclaf Causality Assessment Method score of "probable" or "highly probable" for rifampicin causality. RESULTS: After exclusions, we reviewed 105 patients who took rifampicin for a median of 131 days. Most had primary biliary cholangitis or primary sclerosing cholangitis; 40 (38.1%) were men and median age was 44 years (IQR: 32-57). 44 (41.9%) patients had baseline serum bilirubin >=2 * ULN and 28 (26.7%) ALT >=3 * ULN. 5 (4.8%) developed rifampicin-induced hepatitis at a median of 70(range 27-130) days after drug initiation. No individual or laboratory baseline characteristics were significantly associated with subsequent development of hepatitis. All cases of hepatitis recovered after drug cessation, although one patient was hospitalised and received corticosteroids. CONCLUSIONS: Given the efficacy of rifampicin for an important sub-group of those with cholestatic pruritus, adult patients, including those with jaundice, can be counselled that 95% of prescriptions are safe, and where hepatitis occurs, including at long latency, drug cessation appears effective. PMID- 29468706 TI - Comparative cardiovascular safety of nonsteroidal anti-inflammatory drugs in patients with hypertension: a population-based cohort study. AB - AIMS: Previous studies have suggested that nonsteroidal anti-inflammatory drugs (NSAIDs) may be associated with higher cardiovascular risks. However, few have been active comparison studies that directly assessed the potential differential cardiovascular risk between NSAID classes or across individual NSAIDs. We compared the risk of major cardiovascular events between cyclooxygenase 2 (COX-2) selective and nonselective NSAIDs in patients with hypertension. METHODS: We conducted a cohort study of patients with hypertension who initiated COX-2 selective or nonselective NSAIDs in a population-based Taiwanese database. The outcomes included hospitalization for the following major cardiovascular events: ischaemic stroke, acute myocardial infarction, congestive heart failure, transient ischaemic attack, unstable angina or coronary revascularization. We followed patients for up to 4 weeks, based on the as-treated principle. We used inverse probability weighting to control for baseline and time-varying covariates, and estimated the on-treatment hazard ratios (HRs) and 95% conservative confidence interval (CIs). RESULTS: We identified 2749 eligible COX 2-selective NSAID users and 52 880 eligible nonselective NSAID users. The HR of major cardiovascular events comparing COX-2-selective with nonselective NSAIDs after adjusting for baseline and time-varying covariates was 1.07 (95% CI 0.65, 1.74). We did not observe a differential risk when comparing celecoxib to diclofenac (HR 1.17; 95% CI 0.61, 2.25), ibuprofen (HR 1.36; 95% CI 0.58, 3.18) or naproxen (HR 0.75; 95% CI 0.23, 2.44). There was an increased risk with COX-2 selective NSAIDs, however, when comparing COX-2-selective NSAIDs with mefenamic acid (HR 2.11; 95% CI 1.09, 4.09). CONCLUSIONS: Our results provide important information about the comparative cardiovascular safety of NSAIDs in patients with hypertension. PMID- 29468707 TI - A truth that does not always speak its name: How Hollander and Turowetz's findings confirm and extend the engaged followership analysis of harm-doing in the Milgram paradigm. AB - Hollander and Turowetz (2017, Br. J. Soc. Psychol., 56, 655-674) present important data from post-experimental interviews with participants in Milgram's 'obedience' research. In these, participants responded to various questions about their perceptions of the study and their behaviour by indicating that they trusted the Experimenter not to let them inflict serious harm. Relatively few participants indicated that they acted as they did because they were committed to the Experimenter or to science. We argue, however, that there are two key reasons why this evidence is not inconsistent with claims that harm-doing is a product of engaged followership. The first is that (in contrast to the data obtained from later post-experimental surveys) the conversational logic of the interviews does not topicalize a discussion or valorization of science, but instead requires participants to defend themselves against an accusation of improper behaviour. The second is that participants' accounts of their behaviour nevertheless revolved around expressions of trust in the Experimenter which can themselves be seen as manifestations of shared identity and engaged followership. Nevertheless, we argue that H&T's analysis points to significant ways in which the engaged followership account and its broader implications for understanding perpetrator behaviour can be embellished. PMID- 29468708 TI - Development and clinical application of an evidence-based pharmaceutical care service algorithm in acute coronary syndrome. AB - WHAT IS KNOWN AND OBJECTIVE: Drug therapies are critical for preventing secondary complications in acute coronary syndrome (ACS). The purpose of this study was to develop and apply a pharmaceutical care service (PCS) algorithm for ACS and confirm that it is applicable through a prospective clinical trial. METHODS: The ACS-PCS algorithm was developed according to extant evidence-based treatment and pharmaceutical care guidelines. Quality assurance was conducted through two methods: literature comparison and expert panel evaluation. The literature comparison was used to compare the content of the algorithm with the referenced guidelines. Expert evaluations were conducted by nine experts for 75 questionnaire items. A trial was conducted to confirm its effectiveness. Seventy nine patients were assigned to either the pharmacist-included multidisciplinary team care (MTC) group or the usual care (UC) group. The endpoints of the trial were the prescription rate of two important drugs, readmission, emergency room (ER) visit and mortality. RESULTS AND DISCUSSION: The main frame of the algorithm was structured with three tasks: medication reconciliation, medication optimization and transition of care. The contents and context of the algorithm were compliant with class I recommendations and the main service items from the evidence-based guidelines. Opinions from the expert panel were mostly positive. There were significant differences in beta-blocker prescription rates in the overall period (P = .013) and ER visits (four cases, 9.76%, P = .016) in the MTC group compared to the UC group, respectively. WHAT IS NEW AND CONCLUSION: We developed a PCS algorithm for ACS based on the contents of evidence-based drug therapy and the core concept of pharmacist services.

PMID- 29468710 TI - Variable selection with group structure in competing risks quantile regression. AB - We study the group bridge and the adaptive group bridge penalties for competing risks quantile regression with group variables. While the group bridge consistently identifies nonzero group variables, the adaptive group bridge consistently selects variables not only at group level but also at within-group level. We allow the number of covariates to diverge as the sample size increases. The oracle property for both methods is also studied. The performance of the group bridge and the adaptive group bridge is compared in simulation and in a real data analysis. The simulation study shows that the adaptive group bridge selects nonzero within-group variables more consistently than the group bridge. A bone marrow transplant study is provided as an example. PMID- 29468711 TI - Estimating recurrence and incidence of preterm birth subject to measurement error in gestational age: A hidden Markov modeling approach. AB - Prediction of preterm birth as well as characterizing the etiological factors affecting both the recurrence and incidence of preterm birth (defined as gestational age at birth <= 37 wk) are important problems in obstetrics. The National Institute of Child Health and Human Development (NICHD) consecutive pregnancy study recently examined this question by collecting data on a cohort of women with at least 2 pregnancies over a fixed time interval. Unfortunately, measurement error due to the dating of conception may induce sizable error in computing gestational age at birth. This article proposes a flexible approach that accounts for measurement error in gestational age when making inference. The proposed approach is a hidden Markov model that accounts for measurement error in gestational age by exploiting the relationship between gestational age at birth and birth weight. We initially model the measurement error as being normally distributed, followed by a mixture of normals that has been proposed on the basis of biological considerations. We examine the asymptotic bias of the proposed approach when measurement error is ignored and also compare the efficiency of this approach to a simpler hidden Markov model formulation where only gestational age and not birth weight is incorporated. The proposed model is compared with alternative models for estimating important covariate effects on the risk of subsequent preterm birth using a unique set of data from the NICHD consecutive pregnancy study. PMID- 29468712 TI - New insights in Type I and II CD20 antibody mechanisms-of-action with a panel of novel CD20 antibodies. AB - Based on their mechanisms-of-action, CD20 monoclonal antibodies (mAbs) are grouped into Type I [complement-dependent cytotoxicity (CDC) and antibody dependent cell-mediated cytotoxicity (ADCC)] and Type II [programmed cell death (PCD) and ADCC] mAbs. We generated 17 new hybridomas producing CD20 mAbs of different isotypes and determined unique heavy and light chain sequence pairs for 13 of them. We studied their epitope binding, binding kinetics and structural properties and investigated their predictive value for effector functions, i.e. PCD, CDC and ADCC. Peptide mapping and CD20 mutant screens revealed that 10 out of these 11 new mAbs have an overlapping epitope with the prototypic Type I mAb rituximab, albeit that distinct amino acids of the CD20 molecule contributed differently. Binding kinetics did not correlate with the striking differences in CDC activity among the mIgG2c mAbs. Interestingly, chimerization of mAb m1 resulted in a mAb displaying both Type I and II characteristics. PCD induction was lost upon introduction of a mutation in the framework of the heavy chain affecting the elbow angle, supporting that structural changes within this region can affect functional activities of CD20 mAbs. Together, these new CD20 mAbs provide further insights in the properties dictating the functional efficacy of CD20 mAbs.

AB - Nivolumab is a fully human IgG4 monoclonal antibody directed against programmed cell death protein 1 (PD-1). PD-1 inhibition allows T-cell activation and recruitment to destroy cancer cells. Checkpoint inhibitors have shown significant survival advantage and relatively low side-effects in comparison with conventional chemotherapy in several types of advanced cancer. Granulomatous cutaneous reactions have been reported showing sarcoidal and panniculitic morphology. Here we present a case of drug-induced lichenoid and granulomatous dermatitis after checkpoint inhibitor therapy observed in a 63-year-old male treated with nivolumab for advanced glioblastoma. This morphology has not been previously reported. We documented a high number of CD8+ T-cells within the lesions. Additionally, we review the side-effects observed with the use of checkpoint inhibitors, with special focus on cutaneous manifestations. PMID- 29468714 TI - Consistent gaussian basis sets of double- and triple-zeta valence with polarization quality of the fifth period for solid-state calculations. AB - Consistent basis sets of double- and triple-zeta valence with polarization quality for the fifth period have been derived for periodic quantum-chemical solid-state calculations with the crystalline-orbital program CRYSTAL. They are an extension of the pob-TZVP basis sets, and are based on the full-relativistic effective core potentials (ECPs) of the Stuttgart/Cologne group and on the def2 SVP and def2-TZVP valence basis of the Ahlrichs group. We optimized orbital exponents and contraction coefficients to supply robust and stable self consistent field (SCF) convergence for a wide range of different compounds. The computed crystal structures are compared to those obtained with standard basis sets available from the CRYSTAL basis set database. For the applied hybrid density functional PW1PW, the average deviations of calculated lattice constants from experimental references are smaller with pob-DZVP and pob-TZVP than with standard basis sets.

PMID- 29468715 TI - Clinical safety, tolerability, pharmacokinetics and effects on urinary electrolyte excretion of AZD9977, a novel, selective mineralocorticoid receptor modulator. AB - AIMS: AZD9977 is the first mineralocorticoid receptor modulator in clinical development exerting similar organ protection as eplerenone with minimal urinary electrolyte effects in preclinical studies. The aim was to perform the initial clinical assessment of AZD9977. METHODS: A first-in-human trial explored doses from 5 to 1200 mg. To study effects on urinary electrolyte excretion an additional randomized placebo controlled cross-over four-period clinical trial was performed. Twenty-three healthy volunteers were administered fludrocortisone alone or in combination with AZD9977, eplerenone or both. AZD9977/eplerenone combination was given to assess if AZD9977 can attenuate eplerenone induced natriuresis. RESULTS: AZD9977 at doses from 5 to 1200 mg was safe and well tolerated and pharmacokinetics were compatible with further development. AZD9977 exhibited similar effects on urinary ln [Na+ ]/[K+ ] as eplerenone when using fludrocortisone as mineralocorticoid receptor agonist, and the combination had an additive effect on ln [Na+ K+ ]. CONCLUSIONS: The results in man contradict the results in rodent models driven by aldosterone, in which AZD9977 has minimal electrolyte effects. Future clinical studies with AZD9977 should be performed in presence of endogenous or exogenous aldosterone to assess potential benefit of AZD9977 in patients. PMID- 29468716 TI - Estimation of age effect with change-points on survival of cancer patients. AB - There is a global trend that the average onset age of many human complex diseases is decreasing, and the age of cancer patients becomes more spread out. The age effect on survival is nonlinear in practice and may have one or more important change-points at which the trend of the effect can be very different before and after these threshold ages. Identification of these change-points allows clinical researchers to understand the biologic basis for the complex relation between age and prognosis for optimal prognostic decision. This paper considers estimation of the potentially nonlinear age effect for general partly linear survival models to ensure a valid statistical inference on the treatment effect. A simple and efficient sieve maximum likelihood estimation method that can be implemented easily using standard statistical software is proposed. A data-driven adaptive algorithm to determine the optimal location and the number of knots for the identification of the change-points is suggested. Simulation studies are performed to study the performance of the proposed method. For illustration purpose, the method is applied to a breast cancer data set from the public domain to investigate the effect of onset age on the disease-free survival of the patients. The results revealed that the risk is highest among young patients and young postmenopausal patients, probably because of a change in hormonal environment during a certain phase of menopause. PMID- 29468717 TI - Brysocarpus coccineus (Schum & Thonn) root reinstates sexual competence and testicular function in paroxetine-induced sexual dysfunction in male Wistar rats. AB - The effects of aqueous extract of Brysocarpus coccineus roots (AEBCR) were studied on sexual behaviour and testicular function of paroxetine-induced sexual dysfunction (SD) in male rats. Ninety, sexually matured male rats (150.88 +/- 5.53 g) were assigned into two groups: A and B. Fifteen SD animals from group B were each allotted to B1, B2, B3, B4 and B5 and received distilled water (DW), Powmax M (7.14 mg/kg body weight, b.w.) 50, 100 and 150 mg/kg b.w of AEBCR, respectively, for 7 days while the non-SD animals (group A) received DW. Eleven secondary metabolites were present in AEBCR. The lowered (p < .05) ejaculation frequency, penile erection index and penile grooming, higher mount and intromission frequencies, prolonged (p < .05) latencies of mount, intromission, ejaculation, and post-ejaculatory interval, reduced (p < .05) serum luteinising hormone, follicle stimulating hormone, testosterone, nitric oxide and testicular function indices, degenerated seminiferous tubules and low luminal spermatozoa contents by paroxetine were significantly (p < .05) attenuated and/or reinstated by AEBCR and Powmax M. The restoration of androgen-dependent sexual and testicular functions in SD male rats by AEBCR validates its folkloric use as aphrodisiac. Clinical studies are desirable to ascertain the efficacy of AEBCR in SD. PMID- 29468718 TI - Nurses' turnover intention: The impact of leader-member exchange, organizational identification and job embeddedness. AB - AIM: The aim of this study was to examine the influence of three factors on turnover intention: leader-member exchange quality, organizational identification and job embeddedness. This area of inquiry has not been fully investigated in the literature. BACKGROUND: Employee turnover, particularly of professionals, becomes a very challenging issue. It continually affects organizations in terms of resourcing and developmental costs, manpower instability, day-to-day operations, perception of quality care and efficiency. Therefore, employees' working attitude and behaviour have drawn increasing attention for further research to determine which factors keep them with their employer. DESIGN: A cross-sectional survey was conducted with self-report questionnaires. METHODS: Data were collected from 1,966 nurses from sixteen private general hospitals in Thailand during February June 2016. Hypotheses were tested and analysed by means of a confirmatory factor analysis, structural equation modelling and a bootstrapping procedure. RESULTS: The results revealed the direct relationship between leader-member exchange quality and job embeddedness. Organizational identification played an intermediary role that partially mediated the relationship between leader-member exchange quality on job embeddedness. Analysis also provided support for the mediating effect of organizational identification and turnover intention through job embeddedness. CONCLUSION: This study extends the job embeddedness theory and gains understanding of the antecedent factors that directly and indirectly cause employees to become embedded and lead to predict turnover intention. The findings are pertinent, as few studies have investigated such relationships. The implications provide insights into how organizations can better retain their workforce. PMID- 29468719 TI - Assessing health facility performance in Indonesia using the Pabon-Lasso model and unit cost analysis of health services. AB - Total health care costs have dramatically increased in Indonesia, and health facilities consume the largest share of health resources. This study aims to provide a better understanding of the characteristics of the best-performing health facilities. We use 4 national Indonesian datasets for 2011 and analysed 200 hospitals and 95 health centres. We first apply the Pabon-Lasso model to assess the relative performance of health facilities in terms of bed occupancy rate and the number of admissions per bed; the model gathers together health facilities into 4 sectors representing different levels of productivity. We then use a step-down costing method to estimate the cost per outpatient visit, inpatient, and bed days in hospitals and health centres. We combined both ratio analysis and applied bivariate and multivariate analyses to identify the predictors of the best-performing health facility; 37% of hospitals and 33% of health centres were located in the high-performing sector of the Pabon-Lasso model. The wide variation in unit costs across health facilities presented a basis for benchmarking and identifying relatively efficient units. Combining the unit cost analysis and Pabon-Lasso model, we find that health facility performance is affected by both internal (size and capacity, financing, type of patients, ownership, accreditation status, and staff availability) and external factors (economic status, population education level, location, and population density). Our study demonstrates that it is feasible to identify the best performing health facilities and provides information about how to improve efficiency using simplistic methods. PMID- 29468720 TI - Family management of childhood atopic dermatitis. AB - AIMS: To identify the variables that affect family management of childhood atopic dermatitis and establish a prediction model based on Bandura's self-efficacy theory. BACKGROUND: Atopic dermatitis is a chronic recurrent skin disease and common health problem in childhood. It is necessary to use an approach that includes parental factors when considering the effective management of childhood atopic dermatitis. DESIGN: A cross-sectional study design. METHODS: A convenience sample, comprising 168 Korean mothers caring for a child with atopic dermatitis under the age of 13, was recruited from the paediatric outpatient departments of two general hospitals in Seoul, South Korea. Data were collected using structured self-reported questionnaires including severity, antecedents, effort, self efficacy and family management of childhood atopic dermatitis from 1 November 2015-28 February 2016. Descriptive statistics about the participants and variables were examined and data were analysed using structural equation modelling. RESULTS: The hypothetical model had an adequate fit to the data, indicating that severity, antecedents, effort and self-efficacy influenced family management of childhood atopic dermatitis. CONCLUSION: These results suggest that strategies to support children with atopic dermatitis and their family should consider the influence of such variables. PMID- 29468721 TI - Measurements and simulation of RF heating of implanted stereo electroencephalography electrodes during MR scans. AB - PURPOSE: To assess RF-induced heating during MRI of patients with implanted stereo-electroencephalography electrodes. METHODS: Simulations and experimental measurements using phantom and a head-only transmit/receive coil on a 3T MR system were performed to evaluate temperature increases at the tip of an 8 contact stereo-electroencephalography electrode and an insulated wire partially immersed into the phantom. The lengths of wire producing maximum (resonant condition) and minimum (anti-resonant condition) heating were evaluated for different entry modes and penetration depths. RESULTS: For both wire and stereo electroencephalography electrode, resonant lengths were close to odd integral multiples of RF quarter wavelength in air and antiresonant length close to even integral multiples of RF quarter wavelength, both being unaffected by the entry mode. In the resonant condition, temperature increased by as much as a factor of 10 higher than that at antiresonant condition. Larger penetration depths did not change resonant length, but did lead to increased RF heating. CONCLUSION: For the partially immersed implants like stereo-electroencephalography electrode, the resonant lengths were found to be independent of the penetration depths and entry modes, although the temperature increases may vary. Avoiding such lengths of cables can reduce the risk of tissue heating during in vivo MRI. PMID- 29468722 TI - Podoplanin-positive myofibroblasts: a pathological hallmark of pleuroparenchymal fibroelastosis. AB - Pathological differential diagnoses of pleuroparenchymal fibroelastosis (PPFE) include usual interstitial pneumonia (UIP) and pulmonary apical cap (PAC); however, there are no specific immunostaining makers to distinguish between these diseases. We performed immunohistochemistry using several pleural mesothelial cell-related markers, including cytokeratin-5/6, CAM5.2, WT-1, calretinin, desmin and podoplanin, for PPFE (n = 4), UIP (n = 10) and PAC (n = 3) lung sections. Among the examined markers, in PPFE and PAC lungs podoplanin commonly showed positivity for spindle cells both in thickened pleura and subpleural fibroelastosis lesions; these cells were also stained with alpha-smooth muscle actin, a marker of myofibroblasts. However, even in elastic fibre-rich cases, UIP lungs did not show such podoplanin-positive myofibroblasts in pleura/subpleura and fibroblastic foci. These findings were also verified using immunofluorescence. By contrast, immunohistochemically as well as morphologically, the difference between PPFE and PAC was not apparent. The presence of podoplanin-positive myofibroblasts could be a pathological hallmark of PPFE, suggesting a pathogenic process distinct from UIP but common to PAC. PMID- 29468723 TI - Bayesian nonparametric inference for panel count data with an informative observation process. AB - In this paper, the panel count data analysis for recurrent events is considered. Such analysis is useful for studying tumor or infection recurrences in both clinical trial and observational studies. A bivariate Gaussian Cox process model is proposed to jointly model the observation process and the recurrent event process. Bayesian nonparametric inference is proposed for simultaneously estimating regression parameters, bivariate frailty effects, and baseline intensity functions. Inference is done through Markov chain Monte Carlo, with fully developed computational techniques. Predictive inference is also discussed under the Bayesian setting. The proposed method is shown to be efficient via simulation studies. A clinical trial dataset on skin cancer patients is analyzed to illustrate the proposed approach. PMID- 29468724 TI - A roadmap to advance dementia research in prevention, diagnosis, intervention, and care by 2025. AB - OBJECTIVE: National and global dementia plans have focused on the research ambition to develop a cure or disease-modifying therapy by 2025, with the initial focus on investment in drug discovery approaches. We set out to develop complementary research ambitions in the areas of prevention, diagnosis, intervention, and care and strategies for achieving them. METHODS: Alzheimer's Society facilitated a taskforce of leading UK clinicians and researchers in dementia, UK funders of dementia research, people with dementia, and carer representatives to develop, using iterative consensus methodology, goals and recommendations to advance dementia research. RESULTS: The taskforce developed 5 goals and 30 recommendations. The goals focused on preventing future cases of dementia through risk reduction, maximising the benefit of a dementia diagnosis, improving quality of life, enabling the dementia workforce to improve practice, and optimising the quality and inclusivity of health and social care systems. Recommendations addressed gaps in knowledge and limitations in research methodology or infrastructure that would facilitate research in prioritised areas. A 10-point action plan provides strategies for delivering the proposed research agenda. CONCLUSIONS: By creating complementary goals for research that mirror the need to find effective treatments, we provide a framework that enables a focus for new investment and initiatives. This will support a broader and more holistic approach to research on dementia, addressing prevention, surveillance of population changes in risk and expression of dementia, the diagnostic process, diagnosis itself, interventions, social support, and care for people with dementia and their families. PMID- 29468725 TI - A clinical risk score to identify patients at high risk of very late stent thrombosis. AB - OBJECTIVES: The aim of this study was to determine predictors of very late stent thrombosis (VLST; >1 year after stenting), and to evaluate whether addition of these predictors to the dual antiplatelet therapy (DAPT) score would improve the ability to identify patients at high risk of VLST who might benefit from DAPT. BACKGROUND: VLST is a severe complication of percutaneous coronary intervention (PCI). Extended knowledge about the predictors of VLST is needed to prevent this life-threatening complication. Recent data showed a reduction in VLST after treatment with prolonged DAPT. The DAPT study developed a prediction score to identify patients after PCI who might benefit from prolonged DAPT duration. METHODS: The Dutch stent thrombosis study is a multi-center case-control study. Consecutive patients with definite VLST were included between 2007 and 2014. Baseline characteristics from the index PCI were collected. Independent predictors of VLST were identified and added to the DAPT score to develop the VLST score. RESULTS: In total, 155 VLST cases and 155 matched controls were included. Suboptimal result of stenting, right coronary artery as target vessel, and diffuse coronary artery ectasia were independent predictors of VLST, and added to the DAPT score. The power of the VLST score to identify patients who experienced VLST was increased (AUC, 95%CI; DAPT score: 0.64, 0.57-0.70; VLST score: 0.70, 0.63-0.76, P = 0.010). CONCLUSIONS: Addition of newly identified independent predictors of VLST resulted in a prediction model with a higher ability to identify patients at high risk of VLST who might benefit from prolonged DAPT. PMID- 29468726 TI - Immunohistochemical expression of CD44 in oral squamous cell carcinoma in relation to histomorphological parameters and clinicopathological factors. AB - AIMS: Oral squamous cell carcinoma (OSCC) is characterised by its variable clinical course. In addition to the routinely used TNM and Union for International Cancer Control systems, patient-specific prognostic/predictive biomarkers are needed. Promising biomarkers include the determination of the cancer stem cell compartment, which can be identified by CD44 expression (among other things). The aim of this study was to evaluate the impact of CD44 in OSCC in terms of correlation with histomorphology, especially targeting features of EMT, and its influence on patient prognosis. METHODS AND RESULTS: A well characterised cohort of 108 therapy-naive OSCCs with complete long-term follow-up and matched lymph node metastases were evaluated for CD44 expression by immunohistochemistry. CD44 expression was correlated with histomorphological characteristics (including tumour differentiation and tumour budding), clinicopathological parameters, and follow-up data. Overexpression of CD44 was detected in 37% of OSCCs within the tumour centre, in 39% of OSCCs at the invasive margin, and in 16% of lymph node metastases. CD44 overexpression at the invasive margin was significantly correlated with poor histopathological differentiation, and specifically with high tumour budding activity and single cell invasion as signs of epithelial-mesenchymal transition (EMT). CD44 overexpression within the tumour core region and in lymph node metastases was identified as an independent prognostic factor for poor overall, disease-specific and disease-free survival in subsets of patients with advanced OSCC. CONCLUSION: Our study demonstrates the association of CD44 with tumour aggressiveness and EMT, as well as the independent prognostic impact of CD44 in a subset of OSCCs, which underlines the role of tumour cell stemness as a key factor in malignant behaviour in this disease. PMID- 29468727 TI - Simultaneous multislice triple-echo steady-state (SMS-TESS) T1 , T2 , PD, and off resonance mapping in the human brain. AB - PURPOSE: To investigate the ability of simultaneous multislice triple-echo steady state (SMS-TESS) imaging to provide quantitative maps of multiple tissue parameters, i.e., longitudinal and transverse relaxation times (T1 and T2 ), proton density (PD), and off-resonance (DeltaB0 ), in the human brain at 3T from a single scan. METHODS: TESS acquisitions were performed in 2D mode to reduce motion sensitivity and accelerated by an SMS excitation scheme (CAIPIRINHA) with SENSE reconstruction. SMS-acceleration factors (R) of 2 and 4 were evaluated. The in vitro and in vivo validation process included standard reference scans to analyze the accuracy of T1 , T2 , and DeltaB0 estimates, as well as single-slice TESS measurements. RESULTS: For R = 2, the quantification of T1 , T2 , PD, and DeltaB0 was overall reliable with marginal noise enhancement. T1 and T2 values were in good agreement with the reference measurements and single-slice TESS. For R = 4, the agreement of DeltaB0 with the standard reference was excellent and the determination of T1 , T2 , and PD was reproducible; however, increased variations in T1 and T2 values with respect to single-slice TESS were observed. CONCLUSION: SMS-TESS has shown potential to offer rapid simultaneous T1 , T2 , PD, and DeltaB0 mapping of human brain tissues. PMID- 29468729 TI - Literature overview highlights lack of paediatric donation protocols but identifies common themes that could guide their development. AB - AIM: Paediatric donation is a unique and extremely sensitive process that requires specific knowledge and competencies. Most countries use protocols for organ and tissue donation to ensure optimal care for the donor and family, but these mainly focus on adults. However, the donation process for children differs from adults in many ways. An overview of the literature was performed to identify protocols for the paediatric population. METHODS: PubMed, Web of Science, EMBASE and the Internet were searched up to March 2016 for papers or other sources in English related to specific organ and tissue donation protocols for children and neonates. This comprised title, abstract and then full-text screening of relevant data. RESULTS: We included 12 papers and two electronic sources that were mainly from North America and Europe. Most discussed donations after cardiac death. The recurring themes included identifying potential donors, approaching parents, palliative care and collaboration with organ procurement organisations. Most papers called for paediatric donation policies to be standardised. CONCLUSION: Scientific publications in English on paediatric donation protocols are very scarce. No comprehensive paediatric donation protocol was found. We identified several recurring themes in the literature that could be used to develop such protocols. PMID- 29468728 TI - European Surveillance System on Contact Allergies (ESSCA): polysensitization, 2009-2014. AB - BACKGROUND: Polysensitization, defined as being allergic to three or more haptens from the European baseline series, is considered to reflect increased susceptibility to developing a contact allergy, and is likely to be associated with an impaired quality of life. OBJECTIVES: To evaluate the prevalences of polysensitization across Europe and to analyse factors associated with polysensitization. METHODS: Patch test data collected by the European Surveillance System on Contact Allergies (ESSCA; www.essca-dc.org) in consecutively patch tested patients from January 2009 to December 2014, comprising 11 countries and 57 departments, were retrospectively analysed. RESULTS: A total of 86 416 patients were available for analysis, showing a standardized prevalence of polysensitization of 7.02%, ranging from 12.7% (Austria) to 4.6% (Italy). Allergen pairs with the strongest association are reported for the total population, for South Europe, and for North/Central Europe. Overall, polysensitized patients showed a higher percentage of extreme (+++) positive patch test reactions than oligosensitized patients. Female sex, occupational dermatitis and age > 40 years were risk factors for polysensitization. CONCLUSIONS: The varying prevalences of polysensitization across Europe most likely reflect differences in patient characteristics and referral patterns between departments. Known risk factors for polysensitization are confirmed in a European dermatitis population. PMID- 29468730 TI - Comparison of three treatment strategies for patients with triple-vessel coronary disease and left ventricular dysfunction. AB - INTRODUCTION: Current guidelines recommend coronary artery bypass grafting (CABG) for patients with multivessel coronary disease and left ventricular (LV) dysfunction. However, some patients undergo percutaneous coronary intervention (PCI) or solely medical therapy (MT) in actual practice. The comparison of long term outcomes of these three treatment strategies in real world is unclear. METHODS: A total of 699 consecutive patients in a single centre from 2004 to 2011 who had TVD and LV ejection fraction <=40%, no prior PCI or CABG and had completed a median 6.2-year follow-up were evaluated. The primary endpoint was all-cause death. The secondary endpoints included cardiac death, major adverse cardiovascular and cerebrovascular events (MACCE; composite of all-cause death, myocardial infarction, repeat revascularization, or stroke), and the individual components of the composite endpoint. RESULTS: One hundred forty-two patients (20.3%) underwent PCI, 201 (28.8%) underwent CABG while 356 (50.9%) received MT alone. MT alone was associated with the worst survival (P < 0.001). Compared with PCI, CABG was associated with a similar risk of all-cause death (hazard ratio [HR], 0.86; 95% confidence interval [CI], 0.52-1.41; P = 0.54) but lower risks of cardiac death (HR, 0.47; 95%CI, 0.25-0.91; P = 0.03), repeat revascularization (HR, 0.29; 95%CI, 0.10-0.85; P = 0.02), and MACCE (HR, 0.63; 95%CI, 0.43-0.93; P = 0.02). CONCLUSIONS: For patients with TVD and LV dysfunction, both CABG and PCI were associated with a lower risk of mortality compared with MT alone. Compared with PCI, CABG has a lower risk of cardiac death, repeat revascularization, and MACCE. PMID- 29468733 TI - Reciprocal leadership in clinical supervision comes of age. PMID- 29468732 TI - Antidepressant effects of dammarane sapogenins in chronic unpredictable mild stress-induced depressive mice. AB - Depression is a common, dysthymic, and psychiatric disorder, resulting in enormous social and economic burden. Dammarane sapogenins (DS), an active fraction from oriental ginseng, has shown antidepressant-like effects in chronic restraint rats and sleep interruption-induced mice, and the present study aimed to further confirm the antidepressant effects of DS in a model of chronic unpredictable mild stress (CUMS) and to explore the underlying mechanism. Oral administration of DS (20, 40, and 80 mg/kg) markedly improved depressant-like behaviors, increasing the sucrose intake in the sucrose preference test and reducing the latency in the novelty-suppressed feeding test, and decreasing the immobility time in both the tail suspension and forced swimming tests, compared with the CUMS mice. Biochemical analysis of brain tissue and serum showed that DS treatment restored the decreased hippocampal neurotransmitter concentrations of serotonin, dopamine, norepinephrine (noradrenaline), and gamma-aminobutyric acid, and decreased the elevated of serum hormone levels (corticotrophin releasing factor, adrenocorticotrophic hormone, and corticosterone) induced by CUMS. Our findings confirm that DS exerts an antidepressant-like effect in the CUMS model of depression in mice, and suggest it may be mediated by regulation of neurotransmitters and hypothalamic-pituitary-adrenal axis. PMID- 29468731 TI - Nutritional influences on brain development. AB - : There is increasing evidence from preclinical and human studies that nutrition in the late foetal and early neonatal period has a significant impact on neurodevelopment across the lifespan. Certain nutrients have particularly large effects in this time period, and their deficits cause greater long-term risk. The mechanisms by which nutrients influence early brain growth and the sensitive periods for when certain nutrients should be provided are being elucidated. Assessments of nutritional status that index brain growth and predict long-term development are important to assess the efficacy of early life nutritional therapies. CONCLUSION: Optimizing nutrition during foetal and early postnatal life is a golden opportunity to impact neurodevelopment and brain function across the lifespan. PMID- 29468734 TI - In patients undergoing percutaneous coronary intervention with rotational atherectomy radial access is safer and as efficient as femoral access. AB - INTRODUCTION: Transfemoral approach (TFA) may be preferred access site in order to facilitate complex percutaneous procedures such as rotational atherectomy (RA). Notwithstanding, there is a growing evidence that transradial approach (TRA) is associated with lower access site complication rates and even lower mortality. The aim was to assess in-hospital and 1-year outcomes in patients undergoing RA using TRA, in comparison to TFA. METHODS: A single center observational study included all consecutive patients, who underwent RA from 2010 to 2015. Primary endpoints were procedural success, in-hospital mortality and major adverse cardiovascular events (MACE). Secondary endpoints were 1-year all cause mortality and MACE. RESULTS: The study included 177 patients, 69% in TRA group and 31% in TFA group. Except for male sex and logistic Euroscore II there were no differences in common risk factors. There was no difference in procedural success (95% vs 87%, P = 0.07) with even a trend in favor of TRA. Performing RA via TRA lower amount of contrast volume (P = 0.009) was used and hospital stay after the procedure was shorter (P = 0.004). Periprocedural complication rates were similar, however patients with TFA had significantly higher rate of major access site bleedings (13% vs 1%, P = 0.001), with no differences in mortality and other adverse events both in-hospital and during 1-year observation. CONCLUSIONS: Even though RA is a demanding technique, when performed via TRA allows to maintain the same procedural success and long-term results in comparison to TFA, reduces in-hospital major access site bleedings, lowers the amount of contrast media and shortens hospital stay. PMID- 29468735 TI - Characterization and Manipulation of Spin Orbit Torque in Magnetic Heterostructures. AB - Electrical-current-induced magnetization switching is a keystone concept in the development of spintronics devices. In the last few years, this field has experienced a significant boost with the discovery of spin orbit torque (SOT) in magnetic heterostructures. Here, the recent results as to the characterization and manipulation of SOT in various heavy-metal/ferromagnet heterostructures are summarized. First, different electrical measurement methods that allow the physical features of SOT to be revealed are introduced. Second, it is shown that SOT in magnetic heterostructures can be manipulated via various material engineering approaches. The interfacial and bulk contributions of SOT are also discussed. These results advance the understanding of SOT and provide novel approaches toward energy-efficient spintronic devices. PMID- 29468736 TI - Bioinspired Wood Nanotechnology for Functional Materials. AB - It is a challenging task to realize the vision of hierarchically structured nanomaterials for large-scale applications. Herein, the biomaterial wood as a large-scale biotemplate for functionalization at multiple scales is discussed, to provide an increased property range to this renewable and CO2 -storing bioresource, which is available at low cost and in large quantities. The Progress Report reviews the emerging field of functional wood materials in view of the specific features of the structural template and novel nanotechnological approaches for the development of wood-polymer composites and wood-mineral hybrids for advanced property profiles and new functions. PMID- 29468738 TI - Combined effects of environmental factors on human perception and objective performance: A review of experimental laboratory works. AB - This study reports the outcomes of a literature survey aimed at exploring how different environmental factors-that is acoustic, thermal, visual, and air quality stimuli-interact in affecting building occupants' perception and performance. Recent laboratory studies have been collected, and their methodological approaches reviewed in terms of experimental design, adopted exposures conditions, perception and performance assessment methods. Results have been summarized and compared to identify interaction patterns between environmental factors and possible practical implications for improving the design of both experimental studies and the built environment. The analysis allows highlighting limitations, potential improvements and future opportunities in this field of research, thus providing a reference for further investigations aimed at a deeper understanding, modeling, and prediction of the impacts caused by the main indoor variables on human comfort and performance. PMID- 29468737 TI - School-based study found that physical activity and aerobic fitness predicted increases in total body fat and abdominal fat at a mean age of 9.8 years. AB - AIM: We assessed whether baseline measurements of physical activity, aerobic fitness, body fat and abdominal fat were predictors of changes in body fat measurements over a two-year period. METHODS: The study comprised of 204 children aged 9.8 +/- 0.6 years with a normal body mass distribution, who recruited from four schools in middle-class areas of Malmo, Sweden, from 2001 to 2004. Peak oxygen uptake and physical activity were measured at baseline. Body fat was measured by dual-energy X-ray absorptiometry at baseline and two years later. RESULTS: Physical activity, aerobic fitness and total body fat or abdominal fat were predictors of change in total body fat or abdominal fat over a period of two years. Changes in the percentage of body fat were not related to any of the baseline measurements. CONCLUSION: Our two-year follow-up of children with a mean age of 9.8 years at baseline showed that physical activity, aerobic fitness and body fat or abdominal fat predicted changes in total body fat or abdominal fat, but not the percentage of body fat. PMID- 29468739 TI - Armed conflict, health spending, and HIV. AB - Among current studies, there is still question as to whether conflict increases, decreases, or has no effect on HIV prevalence. This lack of clarity can be attributed to the scarcity of quantitative analysis in this field. Thus, studies about conflict and HIV have failed to specify the ways conflict affects HIV prevalence, if indeed it does. In this paper, I argue that armed conflict increases HIV prevalence by reducing total per capita health spending. Using HIV prevalence data from 1990 to 2009, I find supporting evidence in the case of civil conflicts for these arguments. In addition, I find that as the severity of civil conflict increases, so do HIV rates. These findings have significant policy implications for individual governments, as well as for the international community. PMID- 29468740 TI - Neuroprotective effects of 20(S)-protopanaxatriol (PPT) on scopolamine-induced cognitive deficits in mice. AB - 20(S)-protopanaxatriol (PPT), one of the ginsenosides from Panax ginseng, has been reported to have neuroprotective effects and to improve memory. The present study was designed to investigate the protective effect of PPT on scopolamine induced cognitive deficits in mice. Male Institute of Cancer Research mice were pretreated with 2 different doses of PPT (20 and 40 MUmol/kg) for 27 days by intraperitoneal injection, and scopolamine (0.75 mg/kg) was injected intraperitoneally for 9 days to induce memory impairment. Thirty minutes after the last pretreatment, the locomotor activity was firstly examined to evaluate the motor function of mice. Then, memory-related behaviors were evaluated, and the related mechanism was further researched. It was founded that PPT treatment significantly reversed scopolamine-induced cognitive impairment in the object location recognition experiment, the Morris water maze test, and the passive avoidance task, showing memory-improving effects. PPT also significantly improved cholinergic system reactivity and suppressed oxidative stress, indicated by inhibition of acetylcholinesterase activity, elevation of acetylcholine levels, increasing superoxide dismutase activity and lowering levels of malondialdehyde in the hippocampus. In addition, the expression levels of Egr-1, c-Jun, and cAMP responsive element binding in the hippocampus were significantly elevated by PPT administration. These results suggest that PPT may be a potential drug candidate for the treatment of cognitive deficit in Alzheimer's disease.

AB - BACKGROUND/PURPOSE: The aim of this study was to evaluate skin condition, expensive equipment is required, continuous skin care is difficult. Therefore, we obtain the skin image using mobile camera, and propose a new algorithm that easily and simply extracts skin features. METHODS: We analyze skin features, extracting the wrinkle length, cell area, and the number of cells. To get accurate skin features, we obtain a new skin binary image, and apply Watershed segmentation to it. So, we improve the accuracy of skin analysis. Therefore, we compare and analyze the degree of matching distribution of wrinkles, the shape of the cell, etc., using similarity between the ground truth and the proposed algorithm result image. RESULTS: We extract skin surface features using a mobile camera image, and verify the change in skin features with age. Also, we demonstrate the superiority of the proposed algorithm through the similarity between the ground truth and proposed result image. CONCLUSION: The proposed method in this study shows that the skin surface can be quantitatively evaluated by the similarity with ground truth. We also propose a method to diagnose and manage individual skin condition using a mobile camera in real life. PMID- 29468742 TI - Dog introduction alters the home dust microbiota. AB - Research has largely reported that dog exposure is associated with reduced allergic disease risk. Responsible mechanism(s) are not understood. The goal was to investigate whether introducing a dog into the home changes the home dust microbiota. Families without dogs or cats planning to adopt a dog and those who were not were recruited. Dust samples were collected from the homes at recruitment and 12 months later. Microbiota composition and taxa (V4 region of the 16S rRNA gene) were compared between homes that did and did not adopt a dog. A total of 91 dust samples from 54 families (27 each, dog and no dog; 17 dog and 20 no dog homes with paired samples) were analyzed. A significant dog effect was seen across time in both unweighted UniFrac and Canberra metrics (both P = .008), indicating dog introduction may result in rapid establishment of rarer and phylogenetically related taxa. A significant dog-time interaction was seen in both weighted UniFrac (P < .001) and Bray-Curtis (P = .002) metrics, suggesting that while there may not initially be large relative abundance shifts following dog introduction, differences can be seen within a year. Therefore, dog introduction into the home has both immediate effects and effects that emerge over time. PMID- 29468743 TI - A phytomodulatory hydrogel with enhanced healing effects. AB - The healing performance of a hydrogel composed of hemicelluloses extracted from seeds of Caesalpinia pulcherrima (Fabaceae) and mixed with phytomodulatory proteins obtained from the latex of Calotropis procera was characterized on excisional wounds. The hydrogel did not induce dermal irritability. When topically used on excisional wounds, the hydrogel enhanced healing by wound contraction. Histology and the measurement of inflammatory mediators (myeloperoxidase, interleukin-1beta, and interleukin-6) suggested that the inflammatory phase of the healing process was intensified, stimulating fibroplasia and neovascularization (proliferative phase) and tissue remodeling by increasing new collagen fiber deposition. In addition, reduction on levels of malondialdehyde in the groups that the hydrogel was applied suggested that the oxidative stress was reduced. The hydrogel performed better than the reference drug used, as revealed by the extended thickness of the remodeled epithelium.

AB - All-solid-state lithium batteries (ASSLBs) have the potential to revolutionize battery systems for electric vehicles due to their benefits in safety, energy density, packaging, and operable temperature range. As the key component in ASSLBs, inorganic lithium-ion-based solid-state electrolytes (SSEs) have attracted great interest, and advances in SSEs are vital to deliver the promise of ASSLBs. Herein, a survey of emerging SSEs is presented, and ion-transport mechanisms are briefly discussed. Techniques for increasing the ionic conductivity of SSEs, including substitution and mechanical strain treatment, are highlighted. Recent advances in various classes of SSEs enabled by different preparation methods are described. Then, the issues of chemical stabilities, electrochemical compatibility, and the interfaces between electrodes and SSEs are focused on. A variety of research addressing these issues is outlined accordingly. Given their importance for next-generation battery systems and transportation style, a perspective on the current challenges and opportunities is provided, and suggestions for future research directions for SSEs and ASSLBs are suggested. PMID- 29468746 TI - Surveillance for azoles resistance in Aspergillus spp. highlights a high number of amphotericin B-resistant isolates. AB - Aspergillus spp. are the most common invasive mould infection and are responsible for high mortality. Aspergillus fumigatus is currently of interest because resistance to azole antifungals has emerged. The Campinas University Hospital (HC UNICAMP) receives high-risk patients susceptible to opportunistic infections but there have been no reports of resistant A. fumigatus. This study aimed to assess the susceptibility profile of Aspergillus isolates, specifically looking for azole resistance. ITS and beta-tubulin DNA sequencing was performed on 228 sequential clinical isolates. Broth microdilution susceptibility testing was performed for all isolates. A. fumigatus represented 74% of the isolates followed by Aspergillus flavus (12%). Nine A. fumigatus isolates from 9 different patients showed high MIC values to at least 1 azole, but cyp51A polymorphisms were detected in only 6 isolates and none correlated with known resistance mutations. The most troubling observation was that the minimum inhibitory concentration for amphotericin B was elevated (>=2 mg L-1 ) in 87% of patients with A. flavus isolates and 43% with Aspergillus fumigatus isolates. Given that amphotericin B is used to treat azole-resistant infections, these data highlight the need for continuous surveillance in Aspergillus for all antifungal resistance to implement correct treatment strategies for the management of these pathogens. PMID- 29468747 TI - Biocompatible Semiconductor Quantum Dots as Cancer Imaging Agents. AB - Approximately 1.7 million new cases of cancer will be diagnosed this year in the United States leading to 600 000 deaths. Patient survival rates are highly correlated with the stage of cancer diagnosis, with localized and regional remission rates that are much higher than for metastatic cancer. The current standard of care for many solid tumors includes imaging and biopsy with histological assessment. In many cases, after tomographical imaging modalities have identified abnormal morphology consistent with cancer, surgery is performed to remove the primary tumor and evaluate the surrounding lymph nodes. Accurate identification of tumor margins and staging are critical for selecting optimal treatments to minimize recurrence. Visible, fluorescent, and radiolabeled small molecules have been used as contrast agents to improve detection during real-time intraoperative imaging. Unfortunately, current dyes lack the tissue specificity, stability, and signal penetration needed for optimal performance. Quantum dots (QDs) represent an exciting class of fluorescent probes for optical imaging with tunable optical properties, high stability, and the ability to target tumors or lymph nodes based on surface functionalization. Here, state-of-the-art biocompatible QDs are compared with current Food and Drug Administration approved fluorophores used in cancer imaging and a perspective on the pathway to clinical translation is provided. PMID- 29468748 TI - The effect of dietary soy intake on weight loss, glycaemic control, lipid profiles and biomarkers of inflammation and oxidative stress in women with polycystic ovary syndrome: a randomised clinical trial. AB - BACKGROUND: The present study aimed to evaluate the effects of dietary soy intake on weight loss and metabolic status of patients with polycystic ovary syndrome (PCOS). METHODS: A randomised clinical trial was conducted among 60 women with PCOS. Participants were randomly assigned into two groups to receive either a test diet (n = 30) or a control diet (n = 30) for 8 weeks. Participants in the test group consumed a diet containing 0.8 g protein kg-1 body weight (35% animal proteins, 35% soy protein and 30% vegetable proteins) and participants in the control group consumed a similar diet containing 70% animal proteins and 30% vegetable proteins. RESULTS: Adherence to the test diet, compared with the control diet, resulted in significant decreases [mean (SD)] in body mass index (BMI) [-0.3 (0.6) versus +0.1 (0.5) kg m-2 , P = 0.02], fasting plasma glucose [ 0.2 (0.5) versus +0.1 (0.3) mmol L-1 , P = 0.01], total testosterone [-0.3 (0.7) versus +0.3 (0.3) mmol L-1 , P < 0.001], insulin [-15.0 (18.0) versus +4.8 (18.6) pmol L-1 , P < 0.001] and insulin resistance [-0.6 (0.6) versus +0.2 (0.7), P < 0.001], as well as a significant increase in quantitative insulin sensitivity check index [+0.01 (0.01) versus -0.002 (0.02), P = 0.01]. In addition, significant decreases in triglycerides [-0.1 (0.4) versus +0.2 (0.3) mmol L-1 , P = 0.01] and malondialdehyde (MDA) [-1.2 (1.0) versus +0.2 (1.2) MUmol L-1 , P < 0.001] and significant increases in nitric oxide (NO) [+13.6 (14.1) versus +0.9 (24.3) MUmol L-1 , P = 0.01] and glutathione (GSH) [+170.1 (175.5) versus +24.2 (168.7) MUmol L-1 , P = 0.002] were seen in the test group compared to the control. CONCLUSIONS: Adherence to test diet among subjects with PCOS significantly decreased BMI, glycaemic control, total testosterone, triglycerides and MDA, and significantly increased NO and GSH compared to the control diet. PMID- 29468749 TI - The effect of pre-pregnancy lifestyle counselling on food intakes and association between food intakes and gestational diabetes in high-risk women: results from a randomised controlled trial. AB - BACKGROUND: Healthy diets before and during pregnancy have been suggested to reduce the risk of gestational diabetes (GDM). Several lifestyle intervention studies for pregnant women have reported dietary improvements after counselling. However, evidence concerning the effect of counselling initiated before pregnancy on diets is limited. METHODS: This randomised controlled study explored whether pre-pregnancy lifestyle counselling influenced food intakes, as well as whether changes in food intakes were associated with GDM. The participants comprised 75 women with prior GDM and/or a body mass index >= 30 kg m-2 . Women were randomised into a control or an intervention group, and their food intakes were followed from pre-pregnancy to early pregnancy using a food frequency questionnaire. The control and intervention groups were combined to assess the association between changes in food intakes and GDM. The diagnosis of GDM was based on a 75-g oral glucose tolerance test conducted in the first and second trimester of pregnancy. RESULTS: Pre-pregnancy lifestyle counselling showed no major overall effect on food intakes. The intake of low-fat cheese increased significantly in women who did not develop GDM compared to women who did after adjusting for potential confounders (P = 0.028). This association was not observed for regular-fat cheese. CONCLUSIONS: The findings obtained in the present study suggest that an increased intake of low-fat but not regular-fat cheese between pre-pregnancy and early pregnancy is associated with a lower risk of GDM in high-risk women. PMID- 29468750 TI - Wheezing preschool children with early-onset asthma reveal a specific metabolomic profile. AB - BACKGROUND: Many children of preschool age present with recurrent wheezing. Most of them outgrow their symptoms, while some have early-onset asthma. Aim of this prospective preliminary study was to apply a metabolomic approach to see whether biochemical-metabolic urinary profiles can have a role in the early identification of the children with asthma. METHODS: Preschool children with recurrent wheezing were recruited and followed up for 3 years, after which they were classified as cases of transient wheezing or early-onset asthma. A urine sample was collected at recruitment and analyzed using a metabolomic approach based on UPLC mass spectrometry. RESULTS: Among 34 children aged 4.0 +/- 1.1 years recruited, at the end of the 3-year follow-up, 16 were classified as having transient wheezing and 16 as cases of early-onset asthma. Through a joint multivariate and univariate statistical analyses, we identified a subset of metabolomic variables that enabled the 2 groups to be clearly distinguished. The model built using the identified variables showed an AUC = 0.99 and an AUC = 0.88 on sevenfold full cross-validation (P = .002). CONCLUSIONS: Metabolomic urinary profile can discriminate preschoolers with recurrent wheezing who will outgrow their symptoms from those who have early-onset asthma. These results may pave the way to the characterization of early non-invasive biomarkers capable of predicting asthma development. PMID- 29468751 TI - New Control Over Silicone Synthesis using SiH Chemistry: The Piers-Rubinsztajn Reaction. AB - There is a strong imperative to synthesize polymers with highly controlled structures and narrow property ranges. Silicone polymers do not lend themselves to this paradigm because acids or bases lead to siloxane equilibration and loss of structure. By contrast, elegant levels of control are possible when using the Piers-Rubinsztajn reaction and analogues, in which the hydrophobic, strong Lewis acid B(C6 F5 )3 activates SiH groups, permitting the synthesis of precise siloxanes under mild conditions in high yield; siloxane decomposition processes are slow under these conditions. A broad range of oxygen nucleophiles including alkoxysilanes, silanols, phenols, and aryl alkyl ethers participate in the reaction to create elastomers, foams and green composites, for example, derived from lignin. In addition, the process permits the synthesis of monofunctional dendrons that can be assembled into larger entities including highly branched silicones and dendrimers either using the Piers-Rubinsztajn process alone, or in combination with hydrosilylation or other orthogonal reactions. PMID- 29468752 TI - Bi5+ , Bi(3-x)+ , and Oxygen Vacancy Induced BiOClx I1-x Solid Solution toward Promoting Visible-Light Driven Photocatalytic Activity. AB - BiOClx I1-x solid solutions with different band gaps were synthesized by adjusting the initial Cl to I molar ratios through a chemical precipitation method at room temperature. The structures, morphologies and optical properties of the samples were characterized by XRD, XPS, Raman, SEM, TEM and UV/Vis, respectively. The photocatalytic experiments showed that the BiOCl0.9 I0.1 sample totally decomposed a large concentration of 50 mg L-1 aqueous Rhodamine B (RhB) solution within 12 minutes under visible light irradiation (lambda>420 nm), which is 11 times higher than that of pure BiOI. Furthermore, the electron band structure and density of states of BiOCl, BiOI and BiOClx I1-x have been investigated using the DFT (density functional theory) calculation method and electrochemical methods. It was found that there are multiple crystal defects of Bi5+ , Bi(3-x)+ , and oxygen vacancies in the BiOClx I1-x samples. The results for Mott-Schottky plots and valence-band XPS spectra showed the position of conduction band (CB) for BiOCl0.9 I0.1 was up-shifted, which is favourable to the redox capacity for the photocatalysts. It could be elucidated that the synergistic effects of multiple crystal defects and unique band structure are critical to improving solar driven photocatalytic activity. This work provides a new highlight toward the construction of high property photocatalysts by tuning the crystal defect and band structure in a simple and efficient way. PMID- 29468753 TI - F1012-2 inhibits the growth of triple negative breast cancer through induction of cell cycle arrest, apoptosis, and autophagy. AB - Sesquiterpene lactones (SLs) are plant-derived constituents that have been proved to have potential antitumour activity. However, the intracellular molecular targets of SLs and the underlying molecular mechanisms have not been well elucidated. Here, we report that F1012-2, a novel SL active fraction, isolated from Eupatorium lindleyanum DC., can significantly inhibit the growth of triple negative breast cancer (TNBC) cells (MDA-MB-231 and MDA-MB-468) but has no obvious inhibitory effect on the growth of human mammary epithelial cells (MCF 10A). The related mechanisms on cell growth inhibition of F1012-2 were demonstrated by inducing apoptosis in a caspase-dependent manner through the intrinsic pathway and extrinsic pathway. F1012-2 could also activate autophagy in TNBC cells. Simultaneously, we found that F1012-2-induced apoptosis was enhanced by inhibition of autophagy. Furthermore, F1012-2 could induce cell cycle arrest at G2/M phase with decreasing expression of cyclin B1, cdc2, and upregulating p21, p-cdc2. Also, F1012-2 activated Akt and p38 signalling pathways. In vivo, F1012-2 exhibited a potential antitumour effect in MDA-MB-231 xenografts without apparent toxicity. Taken together, our results identified that F1012-2 inhibited cell growth via multiple signalling pathways in vitro and in vivo. These data suggest that F1012-2 may be a potential natural active fraction for the treatment of TNBC. PMID- 29468754 TI - Prevalence of vitamin B12 deficiency in healthy Indian school-going adolescents from rural and urban localities and its relationship with various anthropometric indices: a cross-sectional study. AB - BACKGROUND: Micronutrient deficiency is a global health burden, especially among developing countries. The present cross-sectional study aimed to determine the prevalence of vitamin B12 deficiency in healthy Indian school-going adolescents, based on area of residence, sex and body mass index (BMI). Furthermore, the relationship of serum B12 concentration with dietary vitamin B12 intake and anthropometric indices was assessed among adolescents from rural and urban India. METHODS: A total of 2403 school-going adolescents (11-17 years) from National Capital Region and rural areas of Haryana, India were selected. Serum B12 concentrations were estimated using an electrochemiluminescence immunoassay. Dietary assessments were conducted on 65% of total participants (n = 1556) by two 24-h diet recalls. RESULTS: The prevalence of vitamin B12 deficiency in the total study population was 32.4% (rural: 43.9% versus urban: 30.1%, P < 0.001; male: 34.4% versus female: 31.0%, P < 0.05; normal weight: 28.1%, versus overweight: 39.8%, versus obese: 51.2%, P < 0.001). More than half (51.2%) of obese adolescents were vitamin B12 deficient. On multiple linear regression analysis, serum B12 in rural adolescents was associated with age (beta = -0.12, P < 0.05). Among urban adolescents, serum B12 was associated with BMI (beta = -0.08, P < 0.05) and adjusted dietary vitamin B12 intake (beta = 0.14, P < 0.001). Serum vitamin B12 levels were found to be lower in rural females (beta = -0.12, P = 0.030) and urban males (beta: 0.11, P < 0.001) compared to their respective contemporaries. CONCLUSIONS: Vitamin B12 deficiency was higher among rural school going adolescents. Boys had a higher B12 deficiency than girls. Inverse associations of serum B12 with adiposity indices were observed. Serum B12 levels were positively associated with dietary vitamin B12 intake. PMID- 29468755 TI - Impact of a mild scrotal heating on sperm chromosomal abnormality, acrosin activity and seminal alpha-glucosidase in human fertile males. AB - The aim of this study was to observe sperm aneuploidy, DNA integrity, seminal alpha-glucosidase (NAG) and acrosin activity (AA) under testicular heat stress (SH). Spermatozoa were obtained from 30 healthy adult volunteers subjected to scrotal warming at 43 degrees C for 30-40 min on two successive days per week for 3 months between February 2012 and September 2016. Aniline blue (AB), acridine orange (AO) staining, TUNEL assay and FISH analysis to evaluate sperm function, sperm DNA integrity and chromosomal abnormalities were carried on before, during and after SH. Sperm AA and NAG was measured by microplate reader. The mean parameters of sperm parameters, AA and NAG were significantly decreased. In contrast, the mean percentage of sperm DNA fragmentation and the proportion of aneuploidy of chromosomes 13, 18, 21, X and Y were significantly increased for spermatozoa collected during SH versus before SH (p < .01-.001). After stopping scrotal heating for 3 months, most parameters were completely restored to pre-SH levels. Sperm parameters, sperm DNA integrity, chromosomes, AA and NAG are affected by scrotal exposure to constant SH temperatures several degrees over normal physiological temperature, and after treatment, these parameters were reversibly restored to the level before SH in adult men. PMID- 29468756 TI - Copper deposition in oligodendroglial cells in an autopsied case of hepatolenticular degeneration. AB - We present a case of hepatolenticular degeneration, so-called Wilson's disease (WD), in a 31-year-old Japanese man with broader deposition of copper in the liver, kidney and brain. The liver showed severe cirrhotic changes with macronodular pseudolobule formation, but there was little difference in immunohistochemical expression patterns of the copper transporter ATP7B between the control and present case. In the brain, there were both WD-related lesions such as the scattering of Opalski cells and changes caused by hepatic encephalopathy including the appearance of Alzheimer type II glia. Of note, we identified copper deposits in the systemic organs, including hepatocytes, renal tubules, and in broad areas of the brain. Surprisingly, as a result of further pursuit, copper accumulation in the brain was rarely identified in neuronal cells, but in Olig2-positive glial cells with double immunohistochemical staining. Together, this rare autopsied case suggests a novel cellular candidate affected by abnormal copper metabolism and the necessity to perform the systemic examination of copper deposition in WD. PMID- 29468757 TI - Anxiolytic and antidepressant activities of Pelargonium roseum essential oil on Swiss albino mice: Possible involvement of serotonergic transmission. AB - The anxiolytic and antidepressant activities of the Reunion Geranium (Pelargonium roseum Willd) essential oil (EO) were evaluated in male Swiss albino mice by intraperitoneal administration of 10, 20, and 50 mg/kg bw using elevated plus maze (EPM), open-field test (OFT), and forced swimming test (FST). Moreover, we evaluated whether the 5-HT1A and GABAA -benzodiazepine receptor systems are involved in the anxiolytic effects through the coadministration of WAY-100635 (a selective 5-HT1A receptor antagonist) and flumazenil (an antagonist of benzodiazepine). GC-MS revealed the monoterpene alcohols citronellol (35.9%) and geraniol (18.5%) as the main components of the P. roseum EO. EO was effective in increasing the total number of entries and time spent in the open arms of EPM whereas number of rearing in OFT was significantly decreased in comparison with the control. In the FST, immobility time decreased in EO treated mice. Pretreatment with WAY-100635, but not Flumazenil, was able to reverse the effects of the EO in the EPM and FST, indicating that the EO activity occurs via the serotonergic but not GABAergic transmission. Overall, results of this work showed significant anxiolytic and antidepressant activity of P. roseum EO and confirmed the traditional uses of Pelargonium species as calming agents. PMID- 29468758 TI - Evidence for Shikonin acting as an active inhibitor of human carboxylesterases 2: Implications for herb-drug combination. AB - Shikonin, a natural naphthoquinone compound derived from the herb Lithospermum erythrorhizon, is widely used for its various pharmacological activities. However, its potential interactions with other medications by inhibiting human carboxylesterases 2 (hCE2) remain unknown. In this study, the inhibitory effects of shikonin on the activity of hCE2 in human liver microsomes are investigated by using fluorescein diacetate (FD), N-(2-butyl-1,3-dioxo-2,3-dihydro-1H-phenalen-6 yl)-2-chloroacetamide (NCEN), and CPT-11 as substrates of hCE2. The results demonstrate that shikonin significantly inhibits the activity of hCE2 when FD and NCEN are used as substrates, whereas the half inhibition concentration value of shikonin increased by 5-30 times when CPT-11 was used as the substrate. The inhibition types of shikonin against hCE2 activity reflected by 3 substrates were all best fit to noncompetitive manners. In addition, shikonin was found to distinctly suppress endogenous hCE2 activity, characterized with attenuated fluorescence. Furthermore, for drugs metabolized by hCE2 with the similar binding sites with FD or NCEN, the estimated magnitudes of area under the curve variation were approximately 9-357% in the presence of shikonin. Also, the area under the curve of CPT-11 could be increased by 1-14% following administration of shikonin. These findings have clear clinical implications for the combination of shikonin and hCE2-metabolizing prodrugs.

PMID- 29468761 TI - Dietary patterns and risk of ulcerative colitis: a case-control study. AB - BACKGROUND: Recent evidence indicates a role for dietary factors in the pathogenesis of ulcerative colitis (UC). The aim of the present study was to investigate the relationship between dietary patterns and UC risk. METHODS: Sixty two newly diagnosed cases of UC and 124 healthy age and sex-matched controls were studied. Data on diet was measured using a validated country-specific food frequency questionnaire. Factor analysis was used to define major dietary patterns based on 28 food groups and nutrient content. RESULTS: After adjustment for confounding factors, subjects who were in the highest tertile of the healthy dietary pattern had a 79% lower risk of UC (odds ratio = 0.21, 95% confidence interval = 0.07-0.59, P = 0.003), whereas the consumption of an unhealthy dietary pattern was associated with a significantly increased risk of UC (odds ratio = 3.39, 95% 95% confidence interval = 1.16-9.90, P = 0.027). CONCLUSIONS: The findings of the present study suggest that dietary patterns are associated with UC risk. PMID- 29468762 TI - Hypolipidemic activity and mechanisms of the total phenylpropanoid glycosides from Ligustrum robustum (Roxb.) Blume by AMPK-SREBP-1c pathway in hamsters fed a high-fat diet. AB - The aim of this study was to evaluate the hypolipidemic effect and mechanisms of total phenylpropanoid glycosides extracted from Ligustrum robustum (Roxb.) Blume (LRTPG) in hamsters fed a high-fat diet and to discover bioactive components in HepG2 cell model induced by oleic acid. LRTPG of high (1.2 g/kg), medium (0.6 g/kg), and low (0.3 g/kg) doses was administrated daily for 21 consecutive days in hamsters. We found that in hamsters fed a high-fat diet, LRTPG effectively reduced the concentrations of plasma triglycerides (TG), free fatty acid, total cholesterol, low-density lipoprotein cholesterol, and hepatic TG and total cholesterol. And the compounds acteoside, ligupurpuroside A, ligupurpuroside C, and ligupurpuroside D significantly inhibited lipid accumulation in HepG2 cell at the concentration of 50 MUmol/L. Mechanism research demonstrated that LRTPG increased the levels of phospho-AMP-activated protein kinase and phospho-sterol regulatory element binding protein-1c in liver, further to suppress the downstream lipogenic genes as stearoyl-CoA desaturase 1, glycerol-3-phosphate acyltransferase, 1-acylglycerol-3-phosphate O-acyltransferase 2, and diacylglycerol acyltransferase 2. In addition, LRTPG increased the hydrolysis of circulating TG by up-regulating lipoprotein lipase activities. These results indicate that LRTPG prevents hyperlipidemia via activation of hepatic AMP activated protein kinase-sterol regulatory element binding protein-1c pathway. PMID- 29468763 TI - Medical marijuana laws and adolescent marijuana use in the United States: a systematic review and meta-analysis. AB - AIMS: To conduct a systematic review and meta-analysis of studies in order to estimate the effect of US medical marijuana laws (MMLs) on past-month marijuana use prevalence among adolescents. METHODS: A total of 2999 papers from 17 literature sources were screened systematically. Eleven studies, developed from four ongoing large national surveys, were meta-analyzed. Estimates of MML effects on any past-month marijuana use prevalence from included studies were obtained from comparisons of pre-post MML changes in MML states to changes in non-MML states over comparable time-periods. These estimates were standardized and entered into a meta-analysis model with fixed-effects for each study. Heterogeneity among the study estimates by national data survey was tested with an omnibus F-test. Estimates of effects on additional marijuana outcomes, of MML provisions (e.g. dispensaries) and among demographic subgroups were abstracted and summarized. Key methodological and modeling characteristics were also described. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. RESULTS: None of the 11 studies found significant estimates of pre-post MML changes compared with contemporaneous changes in non-MML states for marijuana use prevalence among adolescents. The meta-analysis yielded a non-significant pooled estimate (standardized mean difference) of -0.003 (95% confidence interval = -0.012, +0.007). Four studies compared MML with non-MML states on pre-MML differences and all found higher rates of past-month marijuana use in MML states pre-MML passage. Additional tests of specific MML provisions, of MML effects on additional marijuana outcomes and among subgroups generally yielded non-significant results, although limited heterogeneity may warrant further study. CONCLUSIONS: Synthesis of the current evidence does not support the hypothesis that US medical marijuana laws (MMLs) until 2014 have led to increases in adolescent marijuana use prevalence. Limited heterogeneity exists among estimates of effects of MMLs on other patterns of marijuana use, of effects within particular population subgroups and of effects of specific MML provisions. PMID- 29468764 TI - Blood pressure lowering and anti-inflammatory effects of hesperidin in type 2 diabetes; a randomized double-blind controlled clinical trial. AB - Elevated levels of reactive oxygen species under diabetic condition lead to vascular complications and inflammation. This study aimed to examine the effects of hesperidin supplement on blood pressure and inflammatory markers in type 2 diabetes. In this research, 64 patients were randomly allocated to receive 500 mg/day hesperidin or placebo capsules for 6 weeks. Data on systolic blood pressure (SBP), diastolic blood pressure, serum total antioxidant capacity (TAC), tumor necrosis factor alpha, interleukin 6 (IL-6), and high-sensitivity C reactive protein (hs-CRP) were collected at the baseline and at the end of the study. In the hesperidin group, SBP (122.7 +/- 8.5 vs. 119.0 +/- 7.4; p = .005), mean arterial blood pressure (94.2 +/- 5.5 vs. 91.8 +/- 5.5; p = .009), IL-6 (8.3 +/- 2.1 vs. 7.4 +/- 1.8; p = .001), and hs-CRP (1.9 +/- 1.2 vs. 1.1 +/- 0.9; p < .000) decreased whereas TAC increased (0.74 +/- 0.1 vs. 0.82 +/- 0.1; p < .000) in comparison to the baseline values. There was a significant difference in mean percent change of SBP, diastolic blood pressure, mean arterial blood pressure, serum TAC, and inflammatory markers (tumor necrosis factor alpha, IL-6, and hs CRP) between hesperidin and control groups following intervention in adjusted models (p < .05). These results suggest that hesperidin may have antihypertensive and anti-inflammatory effects in type 2 diabetes. PMID- 29468765 TI - Outcomes of paediatric critical care asthma patients. AB - AIM: The aim of this study was to characterise patients with asthma admitted to an Australian paediatric intensive care unit (PICU). METHODS: This was a retrospective review of patients with asthma admitted to a university-affiliated, 23-bed, tertiary PICU between January 2000 and December 2011, with a subset of pharmacotherapy and biochemical data from patients admitted between July 2007 and December 2011. RESULTS: A total of 589 admissions (501 patients) with asthma over 12 years constituted 4.4% of all PICU admissions. Three patients died (0.6%). Non invasive ventilation (NIV) was used in 104 (17.7%) admissions, and 41 (7%) were invasively ventilated. On 12 (2%) occasions, patients received both NIV and invasive ventilation. Over 12 years, there was a significant trend to increased use of NIV, 11-39% (P < 0.0001), and invasive ventilation, 6-14% (P < 0.001). All received steroids and nebulised beta2-agonists. A total of 92% received intravenous (IV) beta2-agonists, 65% of these for less than 12 h. PICU and hospital stay were proportional to the duration of IV beta2-agonist infusion (P < 0.0001). A total of 47.1% received IV magnesium sulphate, increasing from 19 to 75% (P < 0.001). The majority (48%) were transferred directly to PICU from other hospitals. Median PICU stay was 1.04 days (0.72-1.63); hospital stay was 3.16 days (2.29-4.71), and both were unchanged. CONCLUSIONS: Intensive care length of stay (LOS) was unchanged over 12 years. Both invasive and NIV and IV magnesium sulphate use increased. LOS was directly related to the duration of IV beta2 agonist. Asthma patients admitted to PICU typically have a brief stay and have a fairly predictable course. Prospective studies could explore the contribution of IV agents and the role of NIV.

PMID- 29468768 TI - Evaluation of a Realistic Cleansing Protocol for Preventing Discoloration of Denture Resins. AB - PURPOSE: To evaluate the efficacy of a realistic staining/cleansing protocol for long-term prevention of discoloration of denture base resins. MATERIALS AND METHODS: Sixty discs (20 * 2.5 mm) of auto- and heat-polymerizing denture acrylic resins were fabricated following manufacturer's instructions, polished on one side and stored in water (37 degrees C) for 24 hours before they were assigned randomly into 6 groups (3 for each material, n = 10) to receive 220 cycles of three immersion protocols. Group A was immersed in the following baths: (1) filtered coffee at 45 degrees C for 2 minutes, (2) tap water at 24 degrees C for 20 seconds, (3) as bath 1, (4) as bath 2, (5) Corega Extradent cleansing solution at 45 degrees C for 3 minutes, and (6) water at 24 degrees C for 20 seconds. Group B was immersed in the four first baths of group A (without cleansing action) and group C in bath 1 for the cumulative action of 20 cycles (80 minutes in 45 degrees C coffee) and bath 2 for 40 seconds. A noncontact optical interferometric profilometer was used for qualitative evaluation of the specimens and a contact colorimeter to estimate color change values (DeltaEpsilon*ab) at baseline and every 20 cycles in the baths for a total of 220 cycles. Data were statistically analyzed using a 2-way-repeated measures ANOVA with Bonferoni multiple comparisons and trend analysis at alpha = 0.05 level of significance. RESULTS: Data indicated changes in color from 1.7 to 14.2 DeltaEpsilon*ab units. The highest values were related to the number of cycles and group B immersion protocol. Significant differences were found among immersion protocols (p < 0.001) and immersion cycles (p < 0.001) with a significant interaction between protocols and cycles (p < 0.001) but not between denture resins (p = 0.991). CONCLUSION: The evaluated protocol A was found effective in preventing color changes in both denture resins even after a long period of action. Protocol C had a much lower staining effect on both resins than protocol B and behaved similarly to protocol A until 140 to 160 cycles. Therefore, it is probably not appropriate for use in short-term color stability experiments. PMID- 29468769 TI - Minimum spanning tree analysis of the human connectome. AB - One of the challenges of brain network analysis is to directly compare network organization between subjects, irrespective of the number or strength of connections. In this study, we used minimum spanning tree (MST; a unique, acyclic subnetwork with a fixed number of connections) analysis to characterize the human brain network to create an empirical reference network. Such a reference network could be used as a null model of connections that form the backbone structure of the human brain. We analyzed the MST in three diffusion-weighted imaging datasets of healthy adults. The MST of the group mean connectivity matrix was used as the empirical null-model. The MST of individual subjects matched this reference MST for a mean 58%-88% of connections, depending on the analysis pipeline. Hub nodes in the MST matched with previously reported locations of hub regions, including the so-called rich club nodes (a subset of high-degree, highly interconnected nodes). Although most brain network studies have focused primarily on cortical connections, cortical-subcortical connections were consistently present in the MST across subjects. Brain network efficiency was higher when these connections were included in the analysis, suggesting that these tracts may be utilized as the major neural communication routes. Finally, we confirmed that MST characteristics index the effects of brain aging. We conclude that the MST provides an elegant and straightforward approach to analyze structural brain networks, and to test network topological features of individual subjects in comparison to empirical null models. PMID- 29468770 TI - Pessary for prevention of preterm birth in twin pregnancy with short cervix: 3 year follow-up study. AB - OBJECTIVE: A recent randomized clinical trial (ProTWIN) showed that a cervical pessary prevented preterm birth and improved neonatal outcome in women with multiple pregnancy and cervical length (CL) < 38 mm. In this follow-up study, the long-term developmental outcome of these children was evaluated at 3 years' corrected age. METHODS: This was a follow-up study of ProTWIN, a multicenter trial conducted between 2009 and 2012 in which asymptomatic women with a multiple pregnancy were randomized to placement of a cervical pessary or no intervention. Current follow-up and analysis were limited to mothers with a mid-trimester CL < 38 mm (78 women (157 children) in the pessary group and 55 women (111 children) in the control group). At 3 years of corrected age, surviving children were invited for a Bayley Scales of Infant and Toddler Development-third edition (Bayley-III) assessment. Death after randomization or neurodevelopmental disability (Bayley-III score of <= 85, 1 SD below mean) rates were compared between the pessary and control groups, according to the intention-to-treat principle and using multiple imputation for missing data. Mean Bayley-III scores in surviving children were also assessed. A linear mixed-effects model was used to adjust for correlation between children of one mother. RESULTS: From the time of entry in the ProTWIN trial until follow-up at 3 years of age, a total of 27 children had died (six (5%) in the pessary vs 21 (26%) in the control group; odds ratio (OR), 0.13; 95% CI, 0.04-0.48). Bayley-III outcomes were collected for 173/241 (72%) surviving children (114 (75%) in the pessary vs 59 (66%) in the control group). The cumulative incidence of death or survival with a neurodevelopmental disability was 12 (10%) in the pessary vs 23 (29%) in the control group (OR, 0.26; 95% CI, 0.09-0.73). No statistical or clinically relevant differences were found with respect to cognitive, language and motor development among surviving children between the groups. Comparable results were found after multiple imputation. CONCLUSION: In women with twin pregnancy and a CL < 38 mm, the use of a cervical pessary strongly improved survival of the children without affecting neurodevelopment at 3 years' corrected age.

AB - OBJECTIVE: The majority of patients with chronic or gestational hypertension do not develop pre-eclampsia. Home blood-pressure monitoring (HBPM) has the potential to offer a more accurate and acceptable means of monitoring hypertensive patients during pregnancy compared with traditional pathways of frequent outpatient monitoring. The aim of this study was to determine whether HBPM reduces visits to antenatal services and is safe in pregnancy. METHODS: This was a case-control study of 166 hypertensive pregnant women, which took place at St George's Hospital, University of London. Inclusion criteria were: chronic hypertension, gestational hypertension or high risk of developing pre-eclampsia, no significant proteinuria (<= 1+ proteinuria on dipstick testing) and normal biochemical and hematological markers. Exclusion criteria were maternal age < 16 years, systolic blood pressure > 155 mmHg or diastolic blood pressure > 100 mmHg, significant proteinuria (>= 2+ proteinuria on dipstick testing or protein/creatinine ratio > 30 mg/mmol), evidence of small-for-gestational age (estimated fetal weight < 10th centile), signs of severe pre-eclampsia, significant mental health concerns or insufficient understanding of the English language. Pregnant women in the HBPM group were taught how to measure and record their blood pressure using a validated machine at home and attended every 1-2 weeks for assessment depending on clinical need. The control group was managed as per the local protocol prior to the implementation of HBPM. The two groups were compared with respect to number of visits to antenatal services and outcome. RESULTS: There were 108 women in the HBPM group and 58 in the control group. There was no difference in maternal age, parity, body mass index, ethnicity or smoking status between the groups, but there were more women with chronic hypertension in the HBPM group compared with the control group (49.1% vs 25.9%, P = 0.004). The HBPM group had significantly fewer outpatient attendances per patient (6.5 vs 8.0, P = 0.003) and this difference persisted when taking into account differences in duration of monitoring (0.8 vs 1.6 attendances per week, P < 0.001). There was no difference in the incidence of adverse maternal, fetal or neonatal outcome between the two groups. CONCLUSION: HBPM in hypertensive pregnancies has the potential to reduce the number of hospital visits required by patients without compromising maternal and pregnancy outcomes.

AB - Social isolation and loneliness are known to be associated with increased morbidity and mortality. Therefore, reducing social isolation and loneliness may improve such outcomes. In relation to men's health, "Men's Sheds" have been shown as one mechanism to achieve this. Studies in Australia and England have shown social, health and personal benefits; however, this remains an area that has not yet been researched in Scotland. This study, therefore, aimed to assess the characteristics of attendees, self-reported motivations for and the values and benefits of attending the Shed from the views of the attendees themselves. The participants of the study were the members of a Men's Shed in the North of Scotland, which was initially set-up by a small number of core Shedders. A convenience sample was recruited by opportunistic interviewing of participants when they attended the Shed using a mixed methods approach from 1 to 15 November 2016. In the absence of a validated questionnaire, a bespoke questionnaire was developed in several iterative stages. The answers to the questionnaire were transferred to an electronic database and analysed by frequency and thematic analysis. The participants (n = 31) had a mean age (SD) of 69.7 +/- 9.5 with 96.8% being retired, thus the majority of the Shed users were older and retired. The results suggest that there were several benefits from attending the Shed, with an overwhelming majority of the sample reporting personal, social and health benefits-however, more research is needed to determine the magnitude of these. This study has also shown that the men attending the Shed frequently discussed health, which could potentially have a beneficial effect. The Shed therefore, as a community project, has the potential to have a positive impact on health welfare by focusing on the social aspects of life. PMID- 29468774 TI - Flexible parents: joint effects of handicapping and brood size manipulation on female parental care in Nicrophorus vespilloides. AB - Parental care is highly variable, reflecting that parents make flexible decisions in response to variation in the cost of care to themselves and the benefit to their offspring. Much of the evidence that parents respond to such variation derives from handicapping and brood size manipulations, the separate effects of which are well understood. However, little is known about their joint effects. Here, we fill this gap by conducting a joint handicapping and brood size manipulation in the burying beetle Nicrophorus vespilloides. We handicapped half of the females by attaching a lead weight to their pronotum, leaving the remaining females as controls. We also manipulated brood size by providing each female with 5, 20 or 40 larvae. In contrast to what we predicted, handicapped females spent more time provisioning food than controls. We also found that handicapped females spent more time consuming carrion. Furthermore, handicapped females spent a similar amount of time consuming carrion regardless of brood size, whereas controls spent more time consuming carrion as brood increased. Females spent more time provisioning food towards larger broods, and females were more likely to engage in carrion consumption when caring for larger broods. We conclude that females respond to both handicapping and brood size manipulations, but these responses are largely independent of each other. Overall, our results suggest that handicapping might lead to a higher investment into current reproduction and that it might be associated with compensatory responses that negate the detrimental impact of higher cost of care in handicapped parents. PMID- 29468775 TI - Spatiotemporal incidence rate data analysis by nonparametric regression. AB - To monitor the incidence rates of cancers, AIDS, cardiovascular diseases, and other chronic or infectious diseases, some global, national, and regional reporting systems have been built to collect/provide population-based data about the disease incidence. Such databases usually report daily, monthly, or yearly disease incidence numbers at the city, county, state, or country level, and the disease incidence numbers collected at different places and different times are often correlated, with the ones closer in place or time being more correlated. The correlation reflects the impact of various confounding risk factors, such as weather, demographic factors, lifestyles, and other cultural and environmental factors. Because such impact is complicated and challenging to describe, the spatiotemporal (ST) correlation in the observed disease incidence data has complicated ST structure as well. Furthermore, the ST correlation is hidden in the observed data and cannot be observed directly. In the literature, there has been some discussion about ST data modeling. But, the existing methods either impose various restrictive assumptions on the ST correlation that are hard to justify, or ignore partially or entirely the ST correlation. This paper aims to develop a flexible and effective method for ST disease incidence data modeling, using nonparametric local smoothing methods. This method can properly accommodate the ST data correlation. Theoretical justifications and numerical studies show that it works well in practice. PMID- 29468773 TI - A comparison of manual tracing and FreeSurfer for estimating hippocampal volume over the adult lifespan. AB - MRI has become an indispensable tool for brain volumetric studies, with the hippocampus an important region of interest. Automation of the MRI segmentation process has helped advance the field by facilitating the volumetric analysis of larger cohorts and more studies. FreeSurfer has emerged as the de facto standard tool for these analyses, but studies validating its output are all based on older versions. To characterize FreeSurfer's validity, we compare several versions of FreeSurfer software with traditional hand-tracing. Using MRI images of 262 males and 402 females aged 38 to 84, we directly compare estimates of hippocampal volume from multiple versions of FreeSurfer, its hippocampal subfield routines, and our manual tracing protocol. We then use those estimates to assess asymmetry and atrophy, comparing performance of different estimators with each other and with brain atrophy measures. FreeSurfer consistently reports larger volumes than manual tracing. This difference is smaller in larger hippocampi or older people, with these biases weaker in version 6.0.0 than prior versions. All methods tested agree qualitatively on rightward asymmetry and increasing atrophy in older people. FreeSurfer saves time and money, and approximates the same atrophy measures as manual tracing, but it introduces biases that could require statistical adjustments in some studies. PMID- 29468776 TI - Inter-shift variation in unscheduled intensive care unit transfers at a children's hospital. AB - BACKGROUND: The early detection of clinical deterioration and the prompt escalation of care is important but may be limited in the general ward, especially at night. Identifying variations between work shifts in the number of unscheduled in-hospital intensive care unit (ICU) transfers and emergency transfers involving life-threatening conditions may help implement targeted interventions to reduce delayed transfers and improve patient safety and outcomes. METHODS: All unscheduled ICU transfers in a tertiary children's hospital, from January 2013 to December 2016, were reviewed retrospectively. The transfers were categorized into safe transfers and adverse safety events (ASE). The 4 year cumulative numbers for each transfer category in each work shift (day, evening, and night) were assessed for comparison. An ASE was defined as transfer after cardiopulmonary resuscitation or tracheal intubation in the ward, or an unrecognized situation awareness failure event transfer, which was defined as previously reported. RESULTS: Of 244 unscheduled in-hospital ICU transfers, 167 were safe transfers and 77 were ASE. The number of unscheduled transfers and of ASE was highest during the day shift (n = 133 and 40, respectively) and lowest during the night shift (n = 25 and 12, respectively). In contrast, the proportion of ASE in the unscheduled transfers was higher during the night shift (48%) compared with the day and evening shifts (30% and 31%, respectively). CONCLUSIONS: The occurrence of unscheduled ICU transfers was disproportionately low during the night shift, whereas the majority of ASE happened during the day shift. Future studies focusing on unravelling the reasons for such variations are warranted. PMID- 29468777 TI - Caring for crying babies: A mixed-methods study to understand factors influencing nurses' and doctors' management of infant colic. AB - AIM: The aim of this study was to determine the barriers and enablers influencing the uptake of two recommendations from a tertiary paediatric hospital's clinical practice guidelines by maternal and child health nurses (MCHNs) and emergency department (ED) doctors: (i) explaining normal crying; and (ii) avoiding attributing crying to gastro-oesophageal reflux (GOR) and limiting anti-reflux medication use. METHODS: The study was designed as 1-h focus group discussions, guided by the Theoretical Domains Framework, and a short questionnaire, with a purposive sample of MCHNs and ED doctors in Victoria, Australia in (March to September) 2015. Analyses were conducted by inductive content analysis to identify key barriers and enablers. RESULTS: A total of 53 MCHNs and 25 ED doctors participated in 11 discussions. For explaining normal crying, key enablers were: adequate experience/competency, perceiving it was their role to explain and belief it prevented over-medicalisation. The main barriers were time restriction and beliefs about parents' perceptions. For MCHNs, key barriers to avoid attributing crying to GOR were: lack of knowledge and confusion around their role in diagnosing GOR. For ED doctors, key barriers to limiting anti reflux medication were: parents requesting medication, concern about disrupting the parent-primary-care practitioner relationship and belief it was not their role to cease anti-reflux medication. CONCLUSIONS: Overall, MCHN and ED doctors were proficient in describing normal crying. However, several barriers to best practice were identified, including time constraints and belief about consequences of intervening. These results will be used to develop effective interventions to address the identified barriers and enablers to optimise the management of infant colic. PMID- 29468778 TI - Behavioral preference in sequential decision-making and its association with anxiety. AB - In daily life, people often make consecutive decisions before the ultimate goal is reached (i.e., sequential decision-making). However, this kind of decision making has been largely overlooked in the literature. The current study investigated whether behavioral preference would change during sequential decisions, and the neural processes underlying the potential changes. For this purpose, we revised the classic balloon analogue risk task and recorded the electroencephalograph (EEG) signals associated with each step of decision-making. Independent component analysis performed on EEG data revealed that four EEG components elicited by periodic feedback in the current step predicted participants' decisions (gamble vs. no gamble) in the next step. In order of time sequence, these components were: bilateral occipital alpha rhythm, bilateral frontal theta rhythm, middle frontal theta rhythm, and bilateral sensorimotor mu rhythm. According to the information flows between these EEG oscillations, we proposed a brain model that describes the temporal dynamics of sequential decision-making. Finally, we found that the tendency to gamble (as well as the power intensity of bilateral frontal theta rhythms) was sensitive to the individual level of trait anxiety in certain steps, which may help understand the role of emotion in decision-making. PMID- 29468779 TI - Probabilistic measures of climate change vulnerability, adaptation action benefits, and related uncertainty from maximum temperature metric selection. AB - Predictions of the projected changes in species distributions and potential adaptation action benefits can help guide conservation actions. There is substantial uncertainty in projecting species distributions into an unknown future, however, which can undermine confidence in predictions or misdirect conservation actions if not properly considered. Recent studies have shown that the selection of alternative climate metrics describing very different climatic aspects (e.g., mean air temperature vs. mean precipitation) can be a substantial source of projection uncertainty. It is unclear, however, how much projection uncertainty might stem from selecting among highly correlated, ecologically similar climate metrics (e.g., maximum temperature in July, maximum 30-day temperature) describing the same climatic aspect (e.g., maximum temperatures) known to limit a species' distribution. It is also unclear how projection uncertainty might propagate into predictions of the potential benefits of adaptation actions that might lessen climate change effects. We provide probabilistic measures of climate change vulnerability, adaptation action benefits, and related uncertainty stemming from the selection of four maximum temperature metrics for brook trout (Salvelinus fontinalis), a cold-water salmonid of conservation concern in the eastern United States. Projected losses in suitable stream length varied by as much as 20% among alternative maximum temperature metrics for mid-century climate projections, which was similar to variation among three climate models. Similarly, the regional average predicted increase in brook trout occurrence probability under an adaptation action scenario of full riparian forest restoration varied by as much as .2 among metrics. Our use of Bayesian inference provides probabilistic measures of vulnerability and adaptation action benefits for individual stream reaches that properly address statistical uncertainty and can help guide conservation actions. Our study demonstrates that even relatively small differences in the definitions of climate metrics can result in very different projections and reveal high uncertainty in predicted climate change effects. PMID- 29468780 TI - Efficacy of routine catheter tip culture in a neonatal intensive care unit. AB - BACKGROUND: Routine catheter tip cultures are not recommended because some cases of colonization, such as with Staphylococcus aureus, can lead to subsequent bacteremia. To evaluate the safety of colonization without antimicrobial treatment, as well as the effectiveness of routine catheter tip cultures in the neonatal intensive care unit (NICU), we performed a retrospective data analysis in a Japanese community hospital. METHODS: We reviewed all peripherally inserted central venous catheter tip culture results from the NICU ward between April 2012 and June 2017 and noted outcome (i.e. antimicrobial treatment or subsequent infection). We then performed a cost analysis for routine catheter tip culturing on patients who were symptom free during the study period. RESULTS: Of the 93 positive cases in 80 patients from 1,051 catheter tip cultures, seven patients had suspected infection and were treated with antimicrobials. The other 73 symptom-free, positive patients had no subsequent or exacerbated symptoms indicative of an infection, and did not have antimicrobial treatment. The total cost for catheter tip culturing during the study period was Y548 731. After excluding patients with symptoms of infection at the time of culture, the efficacy of routine catheter tip cultures on symptom-free patients was estimated to be zero. CONCLUSION: Symptom-free colonization did not affect clinician management in this study, and all colonized patients without suspected infection were safely managed without antimicrobials. Furthermore, routine catheter tip culturing was not cost-effective; therefore, this practice may be no longer recommended in the NICU. PMID- 29468781 TI - What factors predict the passage of state-level e-cigarette regulations? AB - E-cigarettes are controversial products. They may help addicted smokers to consume nicotine in a less harmful manner or to quit tobacco cigarettes entirely, but these products may also entice youth into smoking. This controversy complicates e-cigarette regulation as any regulation may lead to health improvements for some populations, and health declines for other populations. Using data from 2007 to 2016, we examine factors that are plausibly linked with U.S. state e-cigarette regulations. We find that less conservative states are more likely to regulate e-cigarettes and that states with stronger tobacco lobbies are less likely to regulate e-cigarettes. This information can help policymakers as they determine how best to promote public health through regulation. PMID- 29468782 TI - Perceptions towards disability among social work students in Israel: Development and validation of a new scale. AB - Over the last decades, the disability movement has been advocating for a paradigmatic shift in how disability is perceived and managed: from a medical or individual perspective focusing on the person's body and mind to a social perspective emphasizing the context and barriers of disability. However, we still know little about the perceptions of helping professionals, particularly social workers who work closely with disabled people. Thus, the aim of the current study is to develop and validate a scale-Perceptions Toward Disability Scale (PTDS)-to measure how social workers view disability: as an individual or social category. This paper describes the three phases of the scale's construction. First, scale items were formulated and its content validity was examined. Next, a pilot of 30 social workers completed a questionnaire and an initial exploratory factor analysis was conducted. In the third and main phase, the final draft was completed in 2016 by 565 Israeli social work students to assess its psychometric properties. Both exploratory and confirmatory factorial validity and discriminant validity analyses were conducted. The results of a confirmatory factor analysis revealed two distinct factors: an individual perspective of disability comprised of eight items (alpha = 0.77) and a social perspective of disability comprised of ten (alpha = 0.66). Subsequent analyses supported the scale's discriminant validity as indicated by the lack of an association between the Attitude Toward Disabled Persons Scale (ATDP) and the social model subscale (r = .13, p = .19) and by the weak negative relation with the individual model subscale (r = -.25, p = .01). These findings show that the PTDS possesses promising construct validity and provide support for its utility. This easy-to-administer instrument offers several practical benefits and can serve as a framework for further empirical research regarding social work practice with disabled people.

PMID- 29468784 TI - Discovery of a Fungal Multicopper Oxidase That Catalyzes the Regioselective Coupling of a Tricyclic Naphthopyranone To Produce Atropisomers. AB - Atropisomeric dinapinones A1 and A2 (DPA1 and DPA2) were isolated from a culture of Talaromyces pinophilus FKI-3864. Monapinone coupling enzyme (MCE), which dimerizes naphthopyranone monapinone A (MPA), was purified from a cell-free extract of T. pinophilus FKI-3864. MCE regioselectively dimerizes MPA at the 8,8' positions to synthesize the atropisomers DPA1 and DPA2 in a ratio of approximately 1:2.5 without a cofactor. The optimal pH value and temperature for MCE were 4.0 and 50 degrees C, and the apparent Km and Vmax values for MPA were (72.7+/-23.2) MUm and (1.21+/-0.170) MUmol min-1 mg-1 protein. The MCE polypeptide is significantly homologous with multicopper oxidases. Heterologous expression of MCE and functional analysis confirmed that MCE catalyzes the regioselective coupling reaction of MPA to produce DPA. No fungal multicopper oxidase has previously been reported to catalyze regioselective intermolecular oxidative phenol coupling to produce naphthopyranone atropisomers.

PMID- 29468785 TI - Explaining the heterogeneity of functional connectivity findings in multiple sclerosis: An empirically informed modeling study. AB - To understand the heterogeneity of functional connectivity results reported in the literature, we analyzed the separate effects of grey and white matter damage on functional connectivity and networks in multiple sclerosis. For this, we employed a biophysical thalamo-cortical model consisting of interconnected cortical and thalamic neuronal populations, informed and amended by empirical diffusion MRI tractography data, to simulate functional data that mimic neurophysiological signals. Grey matter degeneration was simulated by decreasing within population connections and white matter degeneration by lowering between population connections, based on lesion predilection sites in multiple sclerosis. For all simulations, functional connectivity and functional network organization are quantified by phase synchronization and network integration, respectively. Modeling results showed that both cortical and thalamic grey matter damage induced a global increase in functional connectivity, whereas white matter damage induced an initially increased connectivity followed by a global decrease. Both white and especially grey matter damage, however, induced a decrease in network integration. These empirically informed simulations show that specific topology and timing of structural damage are nontrivial aspects in explaining functional abnormalities in MS. Insufficient attention to these aspects likely explains contradictory findings in multiple sclerosis functional imaging studies so far. PMID- 29468787 TI - Association of dialysis with in-hospital disability progression and mortality in community-onset stroke. AB - AIM: End-stage renal disease is associated with increased risk of cerebrovascular disease, but the effect on post-stroke clinical outcomes has not been thoroughly investigated. METHODS: Using the Japanese Diagnosis Procedure Combination database, which includes administrative claims and discharge abstract data, we examined the association between risk factors including dialysis therapy and in hospital disability progression or mortality in patients with community-onset stroke. We extracted data of patients aged >=20 years old who were admitted to the hospital within 3 days after onset of stroke between July 2010 and March 2013. The disability level was divided into modified Rankin Scale (mRS) 0-1, 2-3, 4-5, and 6 (death). Disability progression was defined as an increase in disability level. Odds ratios for in-hospital disability progression and mortality were calculated using logistic regression models. RESULTS: Of 435,403 patients, 7,562 (1.7%) received dialysis therapy. The median length of stay was 21 and 20 days for patients with and without dialysis, respectively. During the hospital stay, disability progressed in 100,402 (23.1%) patients and 45,919 (10.5%) died. Patients on dialysis had a higher prevalence of disability progression (26.8%) and mortality (13.1%) compared to those without dialysis (23.0% and 10.5%, respectively). Dialysis was associated with an increased risk of in-hospital disability progression (odds ratio, 1.56; 95% confidence interval, 1.47-1.66) and mortality (odds ratio 1.70; 95% confidence interval, 1.57-1.84). These risks were comparable among subtypes of stroke. CONCLUSIONS: Dialysis was associated with an increased risk of in-hospital disability progression and mortality among patients with community-onset stroke, regardless of stroke subtype.

AB - The compound 6-azaindole undergoes self-assembly by formation of N(1)-H???N(6) hydrogen bonds (H bonds), forming a cyclic, triply H-bonded trimer. The formation phenomenon is visualized by scanning tunneling microscopy. Remarkably, the H bonded trimer undergoes excited-state triple proton transfer (ESTPT), resulting in a proton-transfer tautomer emission maximized at 435 nm (325 nm of the normal emission) in cyclohexane. Computational approaches affirm the thermodynamically favorable H-bonded trimer formation and the associated ESTPT reaction. Thus, nearly half a century after Michael Kasha discovered the double H-bonded dimer of 7-azaindole and its associated excited-state double-proton-transfer reaction, the triply H-bonded trimer formation of 6-azaindole and its ESTPT reaction are demonstrated. PMID- 29468789 TI - The Fourth Alloying Mode by Way of Anti-Galvanic Reaction. AB - Anti-galvanic reaction (AGR) not only defies classic galvanic theory but is a promising method for tuning the compositions, structures, and properties of noble metal nanoparticles. Employing AGR for the preparation of alloy nanoparticles has recently received great interest. Herein, we report an unprecedented alloying mode by way of AGR, in which foreign atoms induce structural transformation of the mother nanoparticles and enter the nanoparticles in a non-replacement fashion. A novel, active-metal-doped, gold nanoparticle was synthesized by this alloying mode, and its structure resolved. A CdSH motif was found in the protecting staples of the bimetal nanoparticle. DFT calculations revealed that the Au20 Cd4 (SH)(SR)19 nanoparticle is a 8e superatom cluster. Furthermore, although the Cd-doping does not essentially alter the absorption spectrum of the mother nanocluster, it distinctly enhances the stability and catalytic selectivity of the mother nanoclusters.

AB - AIM: Children's intake of discretionary choices is excessive. This study aimed to develop a questionnaire measuring parents' attitudes and beliefs towards limiting provision of discretionary choices, using the Health Action Process Approach model. METHODS: The questionnaire items were informed by the Health Action Process Approach model, which extends the Theory of Planned Behaviour to include both motivational (intention) and volitional (post-intention) factors that influence behaviour change. The questionnaire was piloted for content and face validity (expert panel, n = 5; parents, n = 4). Construct and predictive validity were examined in a sample of 178 parents of 4-7-year-old children who completed the questionnaire online. Statistical analyses included exploratory factor analyses, Cronbach's alpha and multiple linear regression. RESULTS: Pilot testing supported content and face validity. Principal component analyses identified constructs that aligned with the eight constructs of the Health Action Process Approach model. Internal consistencies were high for all subscales, in both the motivational (Cronbach's alpha 0.77-0.88) and volitional phase (Cronbach's alpha 0.85-0.92). CONCLUSIONS: Initial results from validation tests support the development of a new questionnaire for measuring parent attitudes and beliefs regarding provision of discretionary choices to their 4-7-year-old children within the home. This new questionnaire can be used to gain greater insight into parents' attitudes and beliefs that influence ability to limit discretionary choices provision to children. Further research to expand understanding of the questionnaires' psychometric properties would be valuable, including confirmatory factor analysis and reproducibility.

AB - Biological responses on biomaterials occur either on their surface or at the interface. Therefore, surface characterization is an essential step in the fabrication of ideal biomaterials for achieving effective control of the interaction between the material surface and the biological environment. Herein, we applied femtosecond laser ablation on electrospun fibrous scaffolds to fabricate various hierarchical patterns with a focus on the alignment of cells. We investigated the simultaneously stimulated response of cardiomyoblasts based on multiple topographical cues, including scales, oriented directions, and spatial arrangements, in the fibrous scaffolds. Our results demonstrated a synergistic effect on cell behaviors of one or more structural arrangements in a homogeneous orientation, whereas antagonistic effects were observed for cells arranged on a surface with heterogeneous directions. Taken together, these results indicate that our hierarchically patterned fibrous scaffolds may be useful tools for understanding the cellular behavior on fibrous scaffolds used to mimic an extracellular matrix-like environment.

AB - Alzheimer's disease (AD) is a very common neurodegenerative disorder in the elderly and brings considerable financial and social problems worldwide. In this study, polyprenols were firstly evaluated the effects on the cognitive deficits and neuropathology in APP/PS1 mice model of AD. At 3 months old, the APP/PS1 mice were divided into model group; polyprenols low, middle, and high dosage group; and positive drug group. Age-matched wild-type mice were chosen in control group. The administration by oral gavage lasted 6 months. Polyprenols treatment significantly improved cognitive impairment of double transgenic mice compared with vehicle control treatment in behavioral tests. In addition, immunohistochemistry and enzyme-linked immunosorbent assay showed that there were significantly reductions in neuritic plaques and the level of hyperphosphorylated tau in brain of polyprenols-treated mice. Furthermore, we found that polyprenols treatment reduced the apoptotic cells in brain sections of 9-month-old APP/PS1 mice. These results reveal that polyprenols exert neuroprotective effects in APP/PS1 mice and could represent an effective treatment for AD. PMID- 29468793 TI - Capacitance for Carbon Capture.

PMID- 29468794 TI - Multiarm-polyethylene glycol-polyglutamic acid peptide dendrimer: Design, synthesis, and dissolving thrombus. AB - Thrombotic events affect many individuals in a number of ways, all of which can cause significant morbidity and mortality. Nattokinase (NK), as a novel thrombolytic drug, has been used for thrombolytic therapy. It not only possesses plasminogen activator activity, but also directly digests fibrin through limited proteolysis. However, it may undergo inactivation and denaturation in the harsh external environment. In this study, a multiarm-polyethylene glycol-polyglutamic acid peptide dendrimer was fabricated and used as a carrier for NK protection and delivery. Different arm numbers of polyethylene glycol-polyglutamic acid peptide dendrimers (x-PEG(G3 )x , x = 2, 4, 6, 8) were designed, prepared, and characterized by 1 H NMR and FTIR. Then, x-PEG(G3 )x were loaded with NK to form nanocomposites. Their size and morphology were determined by dynamic light scattering and transmission electron microscopy. Enzyme activity was evaluated via UV-Vis absorbance spectra, fluorescence spectra, circular dichroism spectra, and zeta potential measurements. The study reveals that the obtained x-PEG(G3 )x /NK nanocomposites possess high enzyme activity. In addition, the nanocomposites show increased viability of rat macrophage cells, and excellent thrombolysis ability in vitro and in vivo. This work establishes a multiarm-polyethylene glycol-polyglutamic acid peptide dendrimer with potential application in NK carrier and thrombolytic therapy. (c) 2018 Wiley Periodicals, Inc.

AB - BACKGROUND: Cirrhosis was previously perceived as a haemorrhagic disease state due to frequent associations with coagulopathy and bleeding. However, the coagulopathy of cirrhosis is complex with defects in both procoagulant and anticoagulant factors. Derangements in common laboratory indices of coagulation do not accurately reflect bleeding risk or protection from thrombotic events. AIMS: To assess the rate of pharmacological prophylaxis for venous thromboembolism (VTE) among hospital inpatients with cirrhosis and analyse factors associated with prophylaxis being inappropriately withheld. METHODS: A retrospective cohort study was performed in a tertiary teaching hospital. Patients included were admitted for greater than 48 h with discharge diagnosis codes corresponding to chronic liver disease and/or cirrhosis. The use of VTE chemoprophylaxis with enoxaparin was assessed in cirrhotic patients and non cirrhotic controls. Patient data collected included contraindications to prophylaxis, known high-risk varices, international normalised ratio (INR), creatinine, bilirubin, haemoglobin and platelet count. RESULTS: Of 108 patients with cirrhosis eligible for VTE prophylaxis, 61 (56.5%) received prophylaxis compared to 104 (96.3%) non-cirrhotic patients. Platelets and INR were significantly different between those who did and did not receive VTE prophylaxis. On multivariate analysis, platelet count and INR were independent predictors for VTE not being administered. CONCLUSION: The administration of chemoprophylaxis in accordance with the hospital guidelines was suboptimal in patients with cirrhosis. Platelet count and INR were independent predictors of prophylaxis use. Our results suggest persistent misperceptions that prolonged INR and thrombocytopenia predict bleeding risk in cirrhosis. PMID- 29468796 TI - Tracking the Oxygen Status in the Cell Nucleus with a Hoechst-Tagged Phosphorescent Ruthenium Complex. AB - Molecular oxygen in living cells is distributed and consumed inhomogeneously, depending on the activity of each organelle. Therefore, tractable methods that can be used to monitor the oxygen status in each organelle are needed to understand cellular function. Here we report the design of a new oxygen-sensing probe for use in the cell nucleus. We prepared "Ru-Hoechsts", each consisting of a phosphorescent ruthenium complex linked to a Hoechst 33258 moiety, and characterized their properties as oxygen sensors. The Hoechst unit shows strong DNA-binding properties in the nucleus, and the ruthenium complex shows oxygen dependent phosphorescence. Thus, Ru-Hoechsts accumulated in the cell nucleus and showed oxygen-dependent signals that could be monitored. Of the Ru-Hoechsts prepared in this study, Ru-Hoechst b, in which the ruthenium complex and the Hoechst unit were linked through a hexyl chain, showed the most suitable properties for monitoring the oxygen status. Ru-Hoechsts are probes with high potential for visualizing oxygen fluctuations in the nucleus. PMID- 29468797 TI - How would you help a colleague dealing with the stress of an adverse outcome? A report from #BlueJC. PMID- 29468798 TI - Tension-free vaginal tape for treatment of pure urodynamic stress urinary incontinence: efficacy and adverse effects at 17-year follow-up. AB - OBJECTIVE: To assess the efficacy and safety of retropubic tension-free vaginal tape (TVT) 17 years after implantation for the treatment of female pure stress urinary incontinence (SUI). PATIENTS AND METHODS: A prospective study was conducted in two urogynaecological units in two countries. All consecutive women with urodynamically proven pure SUI treated by TVT were included. Patients with mixed incontinence and/or anatomical evidence of pelvic organ prolapse were excluded. Data regarding subjective outcomes (International Consultation on Incontinence Questionnaire-Short Form, Patient Global Impression of Improvement, and patient satisfaction scores), objective cure (stress test) rates, and adverse events were collected during follow-up. Univariable analysis was performed to investigate outcomes. RESULTS: A total of 52 women underwent TVT implantation. At 17-year follow-up, 46 women (88.4%) were available for the evaluation. We did not find any significant change in surgical outcomes during this time. At 17 years after surgery, 41 of 46 women (89.1%) declared themselves cured (P = 0.98). Similarly, at 17-year evaluation, 42 of 46 women (91.4%) were objectively cured. No significant deterioration in objective cure rates was observed over time (P for trend 0.50). The univariate analysis did not find any risk factor statistically associated with the recurrence of SUI. Of the 46 women, 15 (32.6%) reported the onset of de novo overactive bladder at 17-year follow-up. No other late complications were reported. CONCLUSIONS: The 17-year results of this study showed that TVT is a highly effective and safe option for the treatment of SUI. PMID- 29468799 TI - A Consensus Model: Shifting assessment practices in dietetics tertiary education. AB - AIM: The aim of this research was to evaluate a Consensus Model for competency based assessment. METHODS: An evaluative case study was used to allow a holistic examination of a constructivist-interpretivist programmatic model of assessment. Using a modified Delphi process, the competence of all 29 students enrolled in their final year of a Master of Nutrition and Dietetics course was assessed by a panel (with expertise in competency-based assessment; industry and academic representation) from a course e-portfolio (that included the judgements of student performance made by worksite educators) and a panel interview. Data were triangulated with assessments from a capstone internship. Qualitative descriptive studies with worksite educators (focus groups n = 4, n = 5, n = 8) and students (personal interviews n = 29) explored stakeholder experiences analysed using thematic analysis. RESULTS: Panel consensus was achieved for all cases by the third-round and corroborated by internship outcomes. For 34% of students this differed to the 'interpretations' of their performance made by their worksite educator/s. Emerging qualitative themes from stakeholder data found the model: (i) supported sustainable assessment practices; (ii) shifted the power relationship between students and worksite educators and (iii) provided a fair method to assess competence. To maximise benefits, more refinement, resources and training are required. CONCLUSIONS: This research questions competency-based assessment practices based on discrete placement units and supports a constructivist-interpretivist programmatic approach where evidence across a whole course of study is considered by a panel of assessors. PMID- 29468800 TI - The influence of matrix stiffness on the behavior of brain metastatic breast cancer cells in a biomimetic hyaluronic acid hydrogel platform. AB - Breast cancer brain metastasis marks the most advanced stage of breast cancer no longer considered curable with a median survival period of ~4-16 months. Apart from the genetic susceptibility (subtype) of breast tumors, brain metastasis is also dictated by the biophysical/chemical interactions of tumor cells with native brain microenvironment, which remain obscure, primarily due to the lack of tunable biomimetic in vitro models. To address this need, we utilized a biomimetic hyaluronic acid (HA) hydrogel platform to elucidate the impact of matrix stiffness on the behavior of MDA-MB-231Br cells, a brain metastasizing variant of the triple negative breast cancer line MDA-MB-231. We prepared HA hydrogels of varying stiffness (0.2-4.5 kPa) bracketing the brain relevant stiffness range to recapitulate the biophysical cues provided by brain extracellular matrix. In this system, we observed that the MDA-MB-231Br cell adhesion, spreading, proliferation, and migration significantly increased with the hydrogel stiffness. We also demonstrated that the stiffness based responses of these cells were mediated, in part, through the focal adhesion kinase phosphoinositide-3 kinase pathway. This biomimetic material system with tunable stiffness provides an ideal platform to further the understanding of mechanoregulation associated with brain metastatic breast cancer cells.

PMID- 29468802 TI - Synergistic effect of strontium, bioactive glass and nano-hydroxyapatite promotes bone regeneration of critical-sized radial bone defects. AB - Critical-sized bone defects constitute a major health issue in orthopedics and usually cause mal-unions due to an inadequate number of migrated progenitor cells into the defect site or their incomplete differentiation into osteogenic precursor cells. The current study aimed to develop an optimized osteoinductive and angiogenic scaffold by incorporation of strontium (Sr) and bioglass (BG) into gelatin/nano-hydroxyapatite (G/nHAp) seeded with bone marrow mesenchymal stem cells to enhance bone regeneration. The scaffolds were fabricated by a freeze drying technique and characterized in terms of morphology, structure, porosity and degradation rate. The effect of fabricated scaffolds on cell viability, attachment and differentiation into osteoblastic lineages was evaluated under in vitro condition. Micro computed tomography scan, histological and histomorphometric analysis were performed after implantation of scaffolds into the radial bone defects in rat. RT-PCR analysis showed that G/nHAp/BG/Sr scaffold significantly increased the expression level of osteogenic and angiogenic markers in comparison to other groups (P < 0.05). Moreover, the defects treated with the BMSCs-seeded scaffolds showed superior bone formation and mechanical properties compared to the cell-free scaffolds 4 and 12 weeks post-implantation. Finally, the BMSCs-seeded G/nHAp/BG/Sr scaffold showed the greatest bone regenerative capacity which was more similar to autograft. It is concluded that combination of Sr, BG, and nHAp can synergistically enhance the bone regeneration process. In addition, our results demonstrated that the BMSCs have the potential to considerably increase the bone regeneration ability of osteoinductive scaffolds. (c) 2018 Wiley Periodicals, Inc.

AB - Pyricularia oryzae is the causal pathogen of rice blast disease. Autophagy has been shown to play important roles in P. oryzae development and plant infection. The P. oryzae endosomal system is highly dynamic and has been shown to be associated with conidiogenesis and pathogenicity as well. To date, the crosstalk between autophagy and endocytosis has not been explored in P. oryzae. Here, we identified three P. oryzae VPS9 domain-containing proteins, PoVps9, PoMuk1 and PoVrl1. We found that PoVps9 and PoMuk1 are localized to vesicles and are each co localized with PoVps21, a recognized marker of early endosomes. Deletion of PoVPS9 resulted in severe defects in endocytosis and autophagosome degradation and impaired the localization of PoVps21 to endosomes. Additionally, deletion of the PoMUK1 gene in the DeltaPovps9 mutant background exhibited more severe defects in development, autophagy and endocytosis compared with the DeltaPovps9 mutant. Pull-down assay showed that PoVps9 interacts with PoVps21, PoRab11 and PoRab1, which have been verified to participate in endocytosis. Furthermore, yeast two-hybrid and co-immunoprecipitation assays confirmed that PoVps9 directly interacts with the GDP form of PoVps21. Thus, PoVps9 is a key protein involved in autophagy and in endocytosis. PMID- 29468803 TI - Gene expression and ultrastructure of meso- and thermophilic methanotrophic consortia. AB - The sulfate-dependent, anaerobic oxidation of methane (AOM) is an important sink for methane in marine environments. It is carried out between anaerobic methanotrophic archaea (ANME) and sulfate-reducing bacteria (SRB) living in syntrophic partnership. In this study, we compared the genomes, gene expression patterns and ultrastructures of three phylogenetically different microbial consortia found in hydrocarbon-rich environments under different temperature regimes: ANME-1a/HotSeep-1 (60 degrees C), ANME-1a/Seep-SRB2 (37 degrees C) and ANME-2c/Seep-SRB2 (20 degrees C). All three ANME encode a reverse methanogenesis pathway: ANME-2c encodes all enzymes, while ANME-1a lacks the gene for N5,N10 methylene tetrahydromethanopterin reductase (mer) and encodes a methylenetetrahydrofolate reductase (Met). The bacterial partners contain the genes encoding the canonical dissimilatory sulfate reduction pathway. During AOM, all three consortia types highly expressed genes encoding for the formation of flagella or type IV pili and/or c-type cytochromes, some predicted to be extracellular. ANME-2c expressed potentially extracellular cytochromes with up to 32 hemes, whereas ANME-1a and SRB expressed less complex cytochromes (<= 8 and <= 12 heme respectively). The intercellular space of all consortia showed nanowire like structures and heme-rich areas. These features are proposed to enable interspecies electron exchange, hence suggesting that direct electron transfer is a common mechanism to sulfate-dependent AOM, and that both partners synthesize molecules to enable it. PMID- 29468805 TI - Aligned nanofiber material supports cell growth and increases osteogenesis in canine adipose-derived mesenchymal stem cells in vitro. AB - Tissue engineering shows great promise for the treatment of degenerative diseases, including bone repair. Polymer nanofibers provide a three-dimensional (3-D) scaffold for attachment and growth of mesenchymal stem cells. Increasing evidence supports that fiber alignment on scaffolds plays a major role in the viability and differentiation of stem cells. We compared the cell viability of canine adipose tissue-derived mesenchymal stem cells (cADMSCs) cultured in the aligned- (NanoAlignedTM) and random- (NanoECMTM) oriented polycaprolactone (PCL) nanofiber-coated plates to control polystyrene tissue culture plates using a proliferation assay. Ability of the plates to induce differentiation of cADMSCs into osteocytes, adipocytes, and neurons was evaluated based on expression of the osteocyte markers, COL1A1 and osterix; adipocyte markers PPARgamma2 and LPL; and neuronal marker nestin using RT-PCR. Proliferation results demonstrated that aligned-oriented PCL nanofiber-coated plates were more suitable substrate for cADMSCs after 7 days in culture compared to random-oriented PCL nanofiber-coated or control plates. Additionally, we demonstrated that both 3-D PCL nanofiber coated plates were a better scaffold for cADMSCs differentiation into osteocytes compared to control plates. In conclusion, our results confirm that PCL nanofiber is a suitable tissue engineering material for use in regenerative medicine for canine patients in vivo. (c) 2018 Wiley Periodicals, Inc.

PMID- 29468807 TI - Fatigue and quasi-static mechanical behavior of bio-degradable porous biomaterials based on magnesium alloys. AB - Magnesium and its alloys have the intrinsic capability of degrading over time in vivo without leaving toxic degradation products. They are therefore suitable for use as biodegradable scaffolds that are replaced by the regenerated tissues. One of the main concerns for such applications, particularly in load-bearing areas, is the sufficient mechanical integrity of the scaffold before sufficient volumes of de novo tissue is generated. In the majority of the previous studies on the effects of biodegradation on the mechanical properties of porous biomaterials, the change in the elastic modulus has been studied. In this study, variations in the static and fatigue mechanical behavior of porous structures made of two different Mg alloys (AZ63 and M2) over different dissolution times ( 6, 12, and 24 h) have been investigated. The results showed an increase in the mechanical properties obtained from stress-strain curve (elastic modulus, yield stress, plateau stress, and energy absorption) after 6-12 h and a sharp decrease after 24 h. The initial increase in the mechanical properties may be attributed to the accumulation of corrosion products in the pores of the porous structure before degradation has considerably proceeded. The effects of mineral deposition was more pronounced for the elastic modulus as compared to other mechanical properties. That may be due to insufficient integration of the deposited particles in the structure of the magnesium alloys. While the bonding of the parts being combined in a composite-like material is of great importance in determining its yield stress, the effects of bonding strength of both parts is much lower in determining the elastic modulus. The results of the current study also showed that the dissolution rates of the studied Mg alloys were too high for direct use in human body.

AB - OBJECTIVES: Incidence of sickle cell disease (SCD) in Ireland has dramatically increased. Disease survival has also steadily improved however cardiovascular manifestations remain important causes of morbidity. These include reports of left ventricular hypertrabeculation (LVHT)/noncompaction. We sought to investigate the prevalence of LVHT among a large cohort of children with SCD. METHODS: We retrospectively reviewed the records of all patients with a diagnosis of SCD who had undergone surveillance echocardiography at Our Lady's Children's Hospital Crumlin (OLCHC) from 1998 to 2015. Demographics, hemoglobin phenotype and treatment information was recorded. LV systolic function, evidence of LVHT, and possible pulmonary arterial hypertension was assessed. RESULTS: Two hundred thirty-six patients had echocardiograms available for interpretation. One hundred twenty-one (51.3%) were female; mean age was 11.3 years (+/- 4.1 years). Twenty six patients (11%) had features of LVHT on echocardiography. Eleven patients (4.7%) had borderline features of LVHT. Mean LVEDD across the whole cohort was 4.2 +/- 0.69 cm, LVEDD z-score of 1.44 +/- 1.9, and mean LVSF was 37.3% +/-15.7%. There were no significant differences in terms of age, LVEDD, LVEDD z-score, or LVSF between patients with and those without LVHT. CONCLUSIONS: The prevalence of LVHT/noncompaction in children with SCD is lower than the adult population and LV systolic function is well preserved throughout our patient group. The mechanism behind the development of LVHT in this population remains speculative. Further work is required in this field. Sickle cell patients require longitudinal evaluation to ascertain changes in left ventricular function and the presence of LVHT/noncompaction. PMID- 29468810 TI - Cellular localization and biological effects of 20nm-gold nanoparticles. AB - Gold nanoparticles (AuNPs) have recently emerged as prominent vehicles for many biomedical applications from sensing to delivery. The relevant literature contains conflicting data about the effects of AuNPs on living cells. The aim of present study is the synthesis and characterization of AuNPs at nanoscale, tracking their cellular localization and determining their effects on cell viability, migration and angiogenesis. Within this scope, 20 nm AuNPs were synthesized and characterized using various spectrometric techniques to determine their size, shape and surface properties such as charge and texture. Two main cell types including mouse fibroblast (L929) and human cervix adenocarcinoma (HeLa) were used in the study to compare the biological effects of colloidal gold on both non-cancer and cancer cells. AuNPs were allowed to interact with HeLa cells to determine their intracellular localization. AuNPs were mainly attached to the cell membrane/membranous compartments and to be captured in small amounts in cytoplasmic vacuoles or to be distributed freely in the cytosol. Scratch assay results showed that AuNPs reduced cancer cell migration especially at increasing concentrations. According to the chick chorioallantoic membrane assay, AuNPs exhibited strong anti-angiogenetic properties and can inhibit vascularization during angiogenesis. In addition, the MTT assay confirmed that AuNP-treated cells caused concentration dependent cytotoxic effects on both cell types. As a result, AuNPs not only have inhibitory effects on cancer cells, but also possess antiangiogenic activity, thus making them a multipotent agent for cancer therapy.

AB - BACKGROUND: The aim of this study is to analyze the progress and the present state of application of robotic rectal surgery in Korea. METHODS: We used data from patients who underwent robotic, laparoscopic or open approaches for four types of operative procedures between 2006 and 2014: (1) anterior resection (AR), (2) low anterior resection (LAR), (3) intersphincteric resection (ISR) and (4) abdominoperineal resection (APR). RESULTS: The number of hospitals performing robotic rectal surgery has increased. Low anterior resection accounts for the largest percentage of robotic surgeries (mean 67.2%), and the number and proportion of ISRs performed robotically have increased rapidly (mean 22.6%). In addition, the dependence on robotic methods for ISR and APR increased rapidly over the study period. CONCLUSION: The use of robotic rectal surgery has widened over the last decade in Korea, and it has been convergent with surgeries for rectal lesions located near the anal verge. PMID- 29468812 TI - Modulation of Schlemm's canal endothelial cell stiffness via latrunculin loaded block copolymer micelles. AB - Increased stiffness of Schlemm's canal endothelial cells (SC cells) is a major contributing factor to the increased pressure characteristic of primary open angle glaucoma. New treatments for glaucoma are being developed using actin depolymerizers and rho kinase inhibitors to address this increased stiffness. However, these agents have off-target effects and are not as potent as had been hoped. We have developed a micellar nanocarrier assembled from poly(ethylene glycol)-bl-poly(propylene sulfide) copolymers capable of encapsulating latrunculin A (Lat A) with the goal of modulating SC cell stiffness. Lat A-loaded nanocarriers were similar in size and morphology to unloaded poly (ethylene glycol)-bl-poly(propylene sulfide) (PEG-bl-PPS) micelles, loaded Lat A at 62% encapsulation efficiency, and retained loaded Lat A for at least 22 days. The continued functional activity of Lat A following encapsulation within micelles was verified in murine macrophages, which are known to display decreased endocytosis in response to Lat A-dependent cytoskeletal disruption. Endocytic inhibition remained unchanged when comparing equal concentrations of micelle loaded versus free form Lat A. Uptake of Lat A-loaded micelles by human SC cells was verified in vitro with no sign of cytotoxicity, and modulation of SC cell stiffness was measured by atomic force microscopy. Lat A-loaded micelles significantly decreased SC cell stiffness, which resulted in visible changes in cell morphology as observed by confocal microscopy. Our results demonstrate that PEG-bl-PPS micelles represent a tunable platform for the controlled intracellular delivery of latrunculin. These self-assembled polymeric nanobiomaterials may support the rational design and engineering of delivery systems for the treatment of glaucoma. (c) 2018 Wiley Periodicals, Inc.

AB - AIM: To assess the acute results of the first human use of the Optimus covered stent in complex coarctation of the aorta. METHODS AND RESULTS: We successfully implanted the Optimus covered stent in eight cases in patients whose preprocedural anatomy looked challenging for currently available covered stents. Six of the patients had native coarctation with one recoarctation following surgical repair. There were no significant complications with reduction in the mean invasive gradient from 22 to 1 mm Hg. The length of stents used ranged from 33 to 57 mm with a median shortening after expansion of 13%. Postprocedural follow-up with magnetic resonance imaging or computed tomography has not shown evidence of fracture or migration or renarrowing. The median duration of follow up is 10 months. CONCLUSIONS: Preliminary results show that the Optimus covered stent is safe and efficacious for use in patients with coarctation of challenging morphology. A systemic trial will be required to evaluate this stent for more widespread practice. PMID- 29468814 TI - Effects of substrate stiffness on dental pulp stromal cells in culture. AB - Dental pulp stromal cells (DPSCs) can be differentiated down lineages known to either express bone or dentin specific protein markers. Since the differentiation of cells can be heavily influenced by their environment, it may be possible to influence the osteogenic/odontogenic potential of DPSCs by modulating the mechanical properties of substrate on which they are grown. In this study, human DPSCs were grown with and without hydroxyapatite (HA) microparticles on a range of substrates including fibronectin-coated hydrogels and glass substrates, which represented an elastic moduli range of approximately 3 kPa-50 GPa, over a 21-day period. Alkaline phosphatase activity, osteopontin production, and mineralization were monitored. The presence of HA microparticles increased the relative degree of mineralized matrix produced by the cells relative to those in the same substrate and media condition without the HA microparticles. In addition, cultures with cells grown on stiffer substrates had higher ALP activity and higher degree of mineralization than those grown on softer substrates. This study shows that DPSCs are affected by the mechanical properties of their underlying growth substrate and by the presence of HA microparticles. In addition, relatively stiff substrates (>75 kPa) may be required for significant mineralization of these cultures. (c) 2018 Wiley Periodicals, Inc. J Biomed Mater Res Part A: 106A: 1789-1797, 2018.

However, translating their utility to human populations has been both limited and challenging. Herein, clinical trials employing two isothiocyanates, sulforaphane (SFN; 1-isothiocyanato-4-(methylsulfinyl) butane) and phenethyl isothiocyanate (PEITC; 2-isothiocyanatoethylbenzene) that are isolated principally from broccoli and watercress, respectively, are summarized and discussed. Both of these compounds have been used in small human clinical trials, either within food matrices or as single agents, against a variety of diseases ranging from cancer to autism. Results suggest an opportunity to incorporate them, or more likely preparations derived from their source plants, into larger human disease mitigation efforts. The context for the applications of these compounds and plants in evidence-based food and nutritional policy is also evaluated. PMID- 29468816 TI - The cholinergic anti-inflammatory pathway revisited. AB - Inflammatory bowel disease negatively affects the quality of life of millions of patients around the world. Although the precise etiology of the disease remains elusive, aberrant immune system activation is an underlying cause. As such, therapies that selectively inhibit immune cell activation without broad immunosuppression are desired. Inhibition of immune cell activation preventing pro-inflammatory cytokine production through neural stimulation has emerged as one such treatment. These therapeutics are based on the discovery of the cholinergic anti-inflammatory pathway, a reflex arc that induces efferent vagal nerve signaling to reduce immune cell activation and consequently mortality during septic shock. Despite the success of preclinical and clinical trials, the neural circuitry and mechanisms of action of these immune-regulatory circuits are controversial. At the heart of this controversy is the protective effect of vagal nerve stimulation despite an apparent lack of neuroanatomical connections between the vagus and target organs. Additional studies have further emphasized the importance of sympathetic innervation of these organs, and that alternative neural circuits could be involved in neural regulation of the immune system. Such controversies also extend to the regulation of intestinal inflammation, with the importance of efferent vagus nerve signals in question. Experiments that better characterize these pathways have now been performed by Willemze et al. in this issue of Neurogastroenterology & Motility. These continued efforts will be critical to the development of better neurostimulator based therapeutics for inflammatory bowel disease. PMID- 29468817 TI - Urinary Excretion of Niacin Metabolites in Humans After Coffee Consumption. AB - SCOPE: Coffee is a major natural source of niacin in the human diet, as it is formed during coffee roasting from the alkaloid trigonelline. The intention of our study was to monitor the urinary excretion of niacin metabolites after coffee consumption under controlled diet. METHODS AND RESULTS: We performed a 4-day human intervention study on the excretion of major niacin metabolites in the urine of volunteers after ingestion of 500 mL regular coffee containing 34.8 MUmol nicotinic acid (NA) and 0.58 MUmol nicotinamide (NAM). In addition to NA and NAM, the metabolites N1 -methylnicotinamide (NMNAM), N1 -methyl-2-pyridone-5 carboxamide (2-Py), and nicotinuric acid (NUA) were identified and quantified in the collected urine samples by stable isotope dilution analysis (SIVA) using HPLC ESI-MS/MS. Rapid urinary excretion was observed for the main metabolites (NA, NAM, NMNAM, and 2-Py), with tmax values within the first hour after ingestion. NUA appeared in traces even more rapidly. In sum, 972 nmol h-1 of NA, NAM, NMNAM, and 2-Py were excreted within 12 h after coffee consumption, corresponding to 6% of the ingested NA and NAM. CONCLUSION: The results indicate regular coffee consumption to be a source of niacin in human diet. PMID- 29468818 TI - ZnO Nanopillar Coated Surfaces with Substrate-Dependent Superbactericidal Property. AB - ZnO nanopillars coated on various surfaces are able to kill adhered bacteria and fungi due to their physical structure through a rupturing mechanism. Remarkably, zinc foil and galvanized steel surfaces with ZnO nanopillar coatings demonstrate an excellent remote bacteria-killing property. Their bacterial killing efficacy is several orders higher than ZnO nanopillars coated on other surfaces as well as ZnO nanoparticles themselves. Mechanistic study shows that the nanostructure surface kills adhered microbial cells by rupturing the cell wall, while superoxide (* O2- ) released from the ZnO coating with electrons donated from zinc via the Zn/ZnO interface rather than photoirritation is responsible for the superior remote killing. The results of this study represent a novel mechanism of surface disinfection and its application in water disinfection is also demonstrated.

AB - Exploration of highly efficient electrocatalysts is significantly urgent for the extensive adoption of the fuel cells. Because of their high activity and super stability, Pt-Pd bimetal nanocrystals have been widely recognized as one class of promising electrocatalysts for oxygen reduction. This article presents the synthesis of popcorn-shaped Pt-Pd bimetal nanoparticles with a wide composition range through a facile hydrothermal strategy. The hollow-centered nanoparticles are surrounded by several petals and concave surfaces. By exploring the oxygen reduction reaction on the carbon supported Pt-Pd popcorns in perchloric acid solution, it is found that compared with the commercial Pt/C catalyst the present catalysts display superior catalytic performances in aspects of catalytic activity and stability. More importantly, the Pt-Pd popcorns display minor performance degradations through prolonged potential cycling. The enhanced performances can be mainly attributed to the unique popcorn structure of the Pt Pd components, which allows the appearance and long existence of the high active sites with more accessibility. The present work highlights the key roles of accessible high active sites in the oxygen reduction reaction, which will ultimately guide the design of highly durable Pt-Pd catalysts. PMID- 29468820 TI - Effects of curcumin consumption on human chronic diseases: A narrative review of the most recent clinical data. AB - Numerous clinical trials have investigated the potential beneficial effects of curcumin supplementation against several human chronic diseases. Up to now, it has been claimed that curcumin consumption may exert beneficial effects against several chronic diseases by promoting human health and preventing diseases. In this aspect, the present review aims to critically collect and in-depth summarize the most recent, well-designed clinical studies evaluating the potential beneficial effects of curcumin consumption on human health promotion and disease prevention. According to recent and well-designed clinical studies, curcumin consumption may benefit against obesity, metabolic syndrome, and diabetes. Moreover, curcumin consumption seems to exert a positive effect on people suffering from various types of cancer, fatty liver disease, depression, arthritis, skin diseases, gut inflammation, and symptoms of premenstrual syndrome. Due to the strong heterogeneity among the clinical studies concerning the exact effective curcumin dose and formulation, as well as the recommended treatment duration for each chronic disease, no precise and definitive conclusions could be drawn. Further large-scale prospective studies are strongly recommended, being well-designed as far as follow-up times, dosage, formulation, and duration of curcumin supplementation are concerned. Moreover, potential confounders in each specific chronic disease should carefully be taken into account in future studies. PMID- 29468821 TI - Urinary Metabolomics Profiles Associated to Bovine Meat Ingestion in Humans. AB - SCOPE: The impact of meat consumption on human health is widely examined in nutritional epidemiological studies, especially due to the connection between the consumption of red and processed meat and the risk of colon cancer. Food questionnaires do not assess the exposure to different methods of meat cooking. This study aimed to identify biomarkers of the acute ingestion of bovine meat cooked with two different processes. METHODS AND RESULTS: Non-targeted UPLC-MS metabolite profiling was done on urine samples obtained from 24 healthy volunteers before and 8 h after the ingestion of a single meal composed of intrinsically 15 N labelled bovine meat, either cooked at 55 degrees C for 5 min or at 90 degrees C for 30 min. A discriminant analysis extension of independent components analysis was applied to the mass spectral data. After meat ingestion, the urinary excretion of 1-methylhistidine, phenylacetylglutamine, and short- and medium-chained acylcarnitines was observed. 15 N labelling was detected in these metabolites, thus confirming their origin from ingested meat. However, no difference was observed in urinary metabolomic profiles according to the meat cooking process used. CONCLUSION: Meat ingestion led to the excretion of several nitrogen-containing compounds, but although a metabolic signature was detected for meat ingestion, the impact of the cooking process was not detectable at the level of urinary metabolic signature in our experimental conditions. PMID- 29468822 TI - Phycoerythrin-Derived Tryptic Peptide of a Red Alga Pyropia yezoensis Attenuates Glutamate-Induced ER Stress and Neuronal Senescence in Primary Rat Hippocampal Neurons. AB - SCOPE: Glutamate excitotoxicity has been observed in association with neurodegenerative disorders. This study aimed to investigate whether a phycoerythrin-derived tryptic peptide of Pyropia yezoensis (PYP) reduces glutamate-induced excitotoxicity and neuronal senescence in primary rat hippocampal neurons. METHODS AND RESULTS: Glutamate exposure (100 MUm) decreased cell viability and increased expression of endoplasmic reticulum (ER) stress response protein glucose-regulated protein 78 (GRP78) starting at 60 min following glutamate exposure, which was prevented by pretreating the neurons with PYP (1 MUg mL-1 ). The glutamate-induced increase in GRP78 expression was downregulated by blocking N-methyl-d-aspartate (NMDA) receptor with MK801 (10 MUm) and inhibiting c-Jun N-terminal kinase (JNK) phosphorylation with SP600125 (10 MUm). Moreover, phosphorylation of JNK was decreased by blockade of NMDA receptor. The PYP pretreatment downregulated glutamate-induced increase in GRP78 expression and JNK phosphorylation, and this effect was abolished by inhibiting tropomyosin-related kinase B (TrkB) receptor, phosphatidylinositiol 3-kinase, and extracellular signal-regulated kinase (ERK)1/2 using cyclotraxin B (200 nm), LY294002 (20 MUm), and SL327 (10 MUm), respectively. In addition, PYP downregulated increase in GRP78 expression, senescence-associated beta galactosidase activity, and neurite degeneration in aging hippocampal neurons. CONCLUSION: These findings indicate that activation of TrkB receptor-mediated ERK1/2 by PYP attenuates glutamate-induced ER stress, which may improve the survival of hippocampal neurons with age. PMID- 29468823 TI - Molecularly Selective Regulation of Delivery Fluxes by Employing Supramolecular Interactions in Layer-by-Layer Films. AB - The molecularly selective regulation of molecular fluxes in a biomaterial that delivers multiple chemical species simultaneously is still beyond the reach of materials scientists. A delivery material was developed by means of the layer-by layer (LbL) technique. This material discriminatively regulates the delivery flux of bioactive small molecules, as represented by a peptide containing the RGD fragment and the chemotherapy drug doxorubicin (DOX). Molecularly selective flux regulations in LbL films are realized through fast, reversible supramolecular interactions between cyclodextrin and its guests. The mechanism underlining the delivery strategy is that supramolecular interactions promote molecular loading and slow down diffusion-dependent release. In a preliminary survey of materials parameters, a maximum difference in cell viability between healthy human bronchial epithelial cells and cancer cells (A549) was realized.

AB - Aqueous Na-ion batteries may offer a solution to the cost and safety issues of high-energy batteries. However, substantial challenges remain in the development of electrode materials and electrolytes enabling high performance and long cycle life. Herein, we report the characterization of a symmetric Na-ion battery with a NASICON-type Na2 VTi(PO4 )3 electrode material in conventional aqueous and "water in-salt" electrolytes. Extremely stable cycling performance for 1000 cycles at a high rate (20 C) is found with the highly concentrated aqueous electrolytes owing to the formation of a resistive but protective interphase between the electrode and electrolyte. These results provide important insight for the development of aqueous Na-ion batteries with stable long-term cycling performance for large scale energy storage. PMID- 29468825 TI - The co-occurrence of anaemia and stunting in young children. AB - Anaemia and stunting are prevalent nutritional problems among children of low income countries that have profound effects on development, morbidity, and mortality. Many use a single conceptual framework to identify the basic determinants of these and other forms of malnutrition. One would expect that problems with matching underlying determinants should co-occur in affected individuals to a greater degree than by chance. In 2 populations of children-ages 6-18 months in Bihar, India, (n = 5,664) and 6-36 months in Lambayeque, Peru (n = 688)-we measured the frequency of the co-occurrence of anaemia and stunting. We compared this value with the value expected by chance, the product of the prevalence of anaemia and stunting, using a chi-square test. We also built logistic regression models for each condition. The frequency of co-occurrence in the Indian population was 21.5%, and in the Peruvian population, it was 30.4%, which are similar to frequencies expected by chance, 21.3% (p = .97) and 31.5% (p = .85). In Peru, anaemia was associated with age and consumption of treated water. Stunting was associated with age, sex, dietary diversity, hand washing, language spoken, and wealth. In India, anaemia was associated with age, sex, caste, dietary diversity, and household hunger. Stunting was associated with age, sex, caste, wealth, and maternal illiteracy. Despite some basic shared factors, anaemia and stunting are more independent than commonly assumed. Interventions that target children based on 1 condition may miss children with the other form of malnutrition.

AB - A cascade reaction of rhodium azavinylcarbenes with Morita-Baylis-Hillman (MBH) adducts enables a novel synthetic approach to 3,4-fused pyrroles. The cascade reaction begins with the insertion of O-H bond into rhodium azavinylcarbenes, subsquent sigmatropic rearrangement provides substituted alpha,beta-unsaturated cyclic ketone intermediates. Then the intramolecular aza Michael addition/oxidative aromatization sequence give rise to a wide range of 3,4-fused pyrroles in good yields, and with excellent functional group compatibility. PMID- 29468827 TI - Exploration of Antigen Induced CaCO3 Nanoparticles for Therapeutic Vaccine. AB - Therapeutic vaccines possess particular advantages and show promising potential to combat burdening diseases, such as acquired immunodeficiency syndrome, hepatitis, and even cancers. An efficient therapeutic vaccine would strengthen the immune system and eventually eliminate target cells through cytotoxic T lymphocytes (CTLs). Unfortunately, insufficient efficacy in triggering such an adaptive immune response is a problem that remains unsolved. To achieve efficient cellular immunity, antigen-presenting cells must capture and further cross present disease-associated antigens to CD8 T cells via major histocompatibility complex I molecules. Here, a biomimetic strategy is developed to fabricate hierarchical ovalbumin@CaCO3 nanoparticles (OVA@NP, ~500 nm) under the templating effect of antigen OVA. Taking advantage of the unique physicochemical properties of crystalline vaterite, cluster structure, and high loading, OVA@NP can efficiently ferry cargo antigen to dendritic cells and blast lysosomes for antigen escape to the cytoplasm. In addition, the first evidence that the physical stress from generated CO2 induces autophagy through the LC3/Beclin 1 pathways is presented. These outcomes cooperatively promote antigen cross presentation, elicit CD8 T cell proliferation, ignite a potent and specific CTL response, and finally achieve prominent tumor therapy effects.

AB - Near-infrared light-mediated theranostic agents with superior tissue penetration and minimal invasion have captivated researchers in cancer research in the past decade. Herein, a probe sonication-assisted liquid exfoliation approach for scalable and continual synthesis of colloidal rhenium disulfide nanosheets, which is further explored as theranostic agents for cancer diagnosis and therapy, is reported. Due to high-Z element of Re (Z = 75) and significant photoacoustic effect, the obtained PVP-capped ReS2 nanosheets are evaluated as bimodality contrast agents for computed tomography and photoacoustic imaging. In addition, utilizing the strong near-infrared absorption and ultrahigh photothermal conversion efficiency (79.2%), ReS2 nanosheets could also serve as therapeutic agents for photothermal ablation of tumors with a tumor elimination rate up to 100%. Importantly, ReS2 nanosheets show no obvious toxicity based on the cytotoxicity assay, serum biochemistry, and histological analysis. This work highlights the potentials of ReS2 nanosheets as a single-component theranostic nanoplatform for bioimaging and antitumor therapy. PMID- 29468829 TI - Disease progression and variation in clinical practice for isolated bicuspid aortic valve in children. AB - BACKGROUND: Disease progression of an isolated bicuspid aortic valve (BAV) in children is poorly understood and adult management guidelines may not be applicable. Thus, we sought to evaluate disease progression of pediatric isolated BAV and its relationship to current management practices. METHODS: Children with a BAV and <=mild aortic stenosis (AS) and/or aortic regurgitation (AR) at the time of initial evaluation were included in this retrospective cohort study (1/2005-12/2014). Outcomes included change in z-scores for aortic root and ascending aorta diameters, cardiac interventions, adverse outcomes, recommended follow-up interval, and frequency of cardiac imaging studies at each follow up evaluation, as well as AS/AR severity at final evaluation. Outcomes were analyzed using generalized mixed-effect models with subject and provider clustering. RESULTS: BAV disease progression was evaluated in 294 subjects over 4.1 +/- 2.4 (range 0.2-9.5) years. Ascending aorta z-scores increased by 0.1/year (P < .001) but aortic root diameter z-scores were unchanged. AS and/or AR progressed to >mild in 9 (3%), 1 subject underwent cardiac intervention, and none had a major complication. Management was evaluated in 454 subjects (1343 encounters) with 27 different cardiologists. The average recommended follow-up interval was 1.5 +/- 0.9 years. Younger age at diagnosis, greater aortic root or ascending aorta z score at diagnosis, >=mild AS/AR at follow-up, and earlier diagnosis era were associated with shorter recommended follow-up interval (P < .001 for all). Imaging was obtained at 87% of follow-up encounters and was associated with age at encounter with children >=12 years most frequently imaged (P < .001). Provider accounted for 14% of variability in recommended follow-up interval and 24% of imaging variability (P < .001 for both). CONCLUSIONS: We found little to no evidence of disease progression in children with an isolated BAV. Given the low risk, close follow-up and frequent cardiac imaging for BAV surveillance may not be warranted for children. PMID- 29468831 TI - The evolutionary stability of attenuators that mask information about animals that social partners can exploit. AB - Signals and cues are fundamental to social interactions. A well-established concept in the study of animal communication is an amplifier, defined as a trait that does not add extra information to that already present in the original cue or signal, but rather enhances the fidelity with which variation in the original cue or signal is correctly perceived. Attenuators as the logical compliment of amplifiers: attenuators act to reduce the fidelity with which variation in a signal or cue can be reliably evaluated by the perceivers. Where amplifiers reduce the effect of noise on the perception of variation, attenuators add noise. Attenuators have been subject to much less consideration than amplifiers; however, they will be the focus of our theoretical study. We utilize an extension of a well-established model incorporated signal or cue inaccuracy and costly investments by emitter and perceiver in sending and attending to the signal or cue. We present broad conditions involving some conflict of interest between emitter and perceiver where it may be advantageous for emitters to invest in costly attenuators to mask cues from potential perceivers, and a subset of these conditions where the perceiver may be willing to invest in costly anti attenuators to mitigate the loss of information to them. We demonstrate that attenuators can be evolutionary stable even if they are costly, even if they are sometimes disadvantageous and even if a perceiver can mount counter-measures to them. As such, we feel that attenuators of cues may be deserving of much more research attention. PMID- 29468830 TI - Concise Review: Is Cardiac Cell Therapy Dead?

PMID- 29468832 TI - Becoming Breastfeeding Friendly Index: Development and application for scaling-up breastfeeding programmes globally. AB - Global efforts to further improve exclusive breastfeeding rates have not been successful, in part because effective scaling-up frameworks and roadmaps have not been developed. The Becoming Breastfeeding Friendly (BBF) toolbox includes an evidence-based index, the BBF Index (BBFI), to guide the development and tracking of large scale, well-coordinated, multisector national breastfeeding promotion programmes. This paper describes the development of the BBFI, which is grounded in the Breastfeeding Gear Model complex adaptive systems framework. The BBFI was developed by the BBF Steering Committee in collaboration with a high-level Technical Advisory Group following the Delphi consensus methodology. Key benchmarks and definitions were informed by evidence-based health, nutrition, and newborn survival initiatives identified from the academic and grey literature. The BBFI consists of 8 gears (54 benchmarks): Advocacy (4); Political Will (3); Legislation and Policies (10); Funding and Resources (4); Training and Program Delivery (17); Promotion (3); Research and Evaluation (10); and Coordination, Goals, and Monitoring (3). Scores are generated for 8 gear scores plus a total country score to gauge the scaling-up enabling environment. The BBFI provides an evidence-based index to assist countries in (a) assessing their readiness to scale up breastfeeding programmes and (b) tracking scaling-up progress. PMID- 29468833 TI - Identification of Three Rheumatoid Arthritis Disease Subtypes by Machine Learning Integration of Synovial Histologic Features and RNA Sequencing Data. AB - OBJECTIVE: In this study, we sought to refine histologic scoring of rheumatoid arthritis (RA) synovial tissue by training with gene expression data and machine learning. METHODS: Twenty histologic features were assessed in 129 synovial tissue samples (n = 123 RA patients and n = 6 osteoarthritis [OA] patients). Consensus clustering was performed on gene expression data from a subset of 45 synovial samples. Support vector machine learning was used to predict gene expression subtypes, using histologic data as the input. Corresponding clinical data were compared across subtypes. RESULTS: Consensus clustering of gene expression data revealed 3 distinct synovial subtypes, including a high inflammatory subtype characterized by extensive infiltration of leukocytes, a low inflammatory subtype characterized by enrichment in pathways including transforming growth factor beta, glycoproteins, and neuronal genes, and a mixed subtype. Machine learning applied to histologic features, with gene expression subtypes serving as labels, generated an algorithm for the scoring of histologic features. Patients with the high inflammatory synovial subtype exhibited higher levels of markers of systemic inflammation and autoantibodies. C-reactive protein (CRP) levels were significantly correlated with the severity of pain in the high inflammatory subgroup but not in the others. CONCLUSION: Gene expression analysis of RA and OA synovial tissue revealed 3 distinct synovial subtypes. These labels were used to generate a histologic scoring algorithm in which the histologic scores were found to be associated with parameters of systemic inflammation, including the erythrocyte sedimentation rate, CRP level, and autoantibody levels. Comparison of gene expression patterns to clinical features revealed a potentially clinically important distinction: mechanisms of pain may differ in patients with different synovial subtypes. PMID- 29468835 TI - Gastrointestinal Symptoms in Patients Receiving Dialysis: A Systematic Review. AB - AIM: To describe the prevalence of all Gastrointestinal (GI) symptoms reported by dialysis patients, as well as the tools being used for diagnosis. BACKGROUND: GI symptoms are commonly reported in patients having haemodialysis (HD) and peritoneal dialysis (PD), but there are multiple definitions and assessment tools reported in the literature. METHODS: A comprehensive systematic review was undertaken using five databases (Embase, Medline, CINAHL, Psycinfo and Web of Science) between 1996 and 2017. Articles were critically appraised using the Newcastle Ottawa Scale (NOS). Data collected was analysed in a Microsoft Excel spreadsheet. RESULTS: Thirty studies (24 cross sectional, 6 cohort) met the inclusion criteria. In total 5,161 patients were studied (3,804 HD and 1,507 PD). Fifteen studies included HD, five includedPD and ten included both dialysis modalities. GI symptoms were heterogeneous, with the reported prevalence highly dependent on the definitions used, inclusion/exclusion criteria, assessment tools and methods used. The most prevalent symptoms were constipation, indigestion, abdominal pain and reflux. Medication use and dietary data were poorly reported. The most common tools used were Gastrointestinal Symptom Rating Scale (GSRS), Rome II and Rome III. Constipation was more common in HD patients than PD patients. Indigestion, abdominal pain and reflux were commonly reported in both dialysis modalities. CONCLUSIONS: GI symptoms are highly prevalent in people on dialysis; however, the evidence base is limited and further investigation of preventable causes and potential interventions such as medications and diet is required in future research. PMID- 29468834 TI - Peripheral blood clinical laboratory variables associated with outcomes following combination nivolumab and ipilimumab immunotherapy in melanoma. AB - Both the combination of nivolumab + ipilimumab and single-agent anti-PD-1 immunotherapy have demonstrated survival benefit for patients with advanced melanoma. As the combination has a high rate of serious side effects, further analyses in randomized trials of combination versus anti-PD-1 immunotherapy are needed to understand who benefits most from the combination. Clinical laboratory values that were routinely collected in randomized studies may provide information on the relative benefit of combination immunotherapy. To prioritize which clinical laboratory factors to ultimately explore in these randomized studies, we performed a single-center, retrospective analysis of patients with advanced melanoma who received nivolumab + ipilimumab either as part of a clinical trial (n = 122) or commercial use (n = 87). Baseline routine laboratory values were correlated with overall survival (OS) and overall response rate (ORR). Kaplan-Meier estimation and Cox regression were performed. Median OS was 44.4 months, 95% CI (32.9, Not Reached). A total of 110 patients (53%) responded (CR/PR). Significant independent variables for favorable OS included the following: high relative eosinophils, high relative basophils, low absolute monocytes, low LDH, and a low neutrophil-to-lymphocyte ratio. These newly identified factors, along with those previously reported to be associated with anti-PD-1 monotherapy outcomes, should be studied in the randomized trials of nivolumab + ipilimumab versus anti-PD-1 monotherapies to determine whether they help define the patients who benefit most from the combination versus anti-PD-1 alone. PMID- 29468836 TI - Combining advantages: Direct correlation of two-dimensional microcomputed tomography datasets onto histomorphometric slides to quantify three-dimensional bone volume in scaffolds. AB - Microcomputed tomography (mCT) belongs to the most powerful tools for the three dimensional (3D) assessment of bone. While it is possible to refer to landmarks in mCT scans of actual bone structure, the assessment of calcified osteoid within scaffolds is problematic, due to the missing morphological correlates. Therefore, bone formation within scaffolds is mostly analyzed using indirect parameters such as changes in volume or surface alteration, preserving histomorphometry the gold standard in the direct analysis of bone formation. The presented method combines the advantages of mCT and histomorphometry: by creating an overlay image of the exact same histomorphometric and mCT slice, a grey-value-threshold representing calcified tissue was defined. Compared to the scaffolds global threshold, a direct evaluation of bone formation within scaffolds is possible by mCT-applied on the whole dataset, evaluation of bone volume is achievable. Two groups of human mesenchymal-stem-cell-seeded beta-Tricalciumphosphate-scaffolds were analyzed: whilst group B was stimulated with 0.1 ug/mL Bone Morphogenetic Protein 7, group A remained unstimulated during in vivo differentiation. Strong correlations (r > 0.8) were obtained between percentage bone area in mCT and histomorphometry, as well as for 3D bone volume. Using the presented method, 3D bone volume can be directly estimated within scaffolds by combination of histomorphometric and mCT-analysis. (c) 2018 Wiley Periodicals, Inc.

Herein, recent advances in nanomaterial preparation by extrusion through nanoporous membranes that preserve the template membrane without sacrificing it, which is termed as "non-sacrificing template synthesis," are reviewed. First, the types of nanoporous membranes used in nanoporous membrane extrusion applications are introduced. Next, four common nanoporous membrane extrusion strategies: vesicle extrusion, membrane emulsification, precipitation extrusion, and biological membrane extrusion, are examined. These methods have been utilized to prepare a wide range of nanomaterials, including liposomes, emulsions, nanoparticles, nanofibers, and nanotubes. The principle and historical context of each specific technology are discussed, presenting prominent examples and evaluating their positive and negative features. Finally, the current challenges and future opportunities of nanoporous membrane extrusion methods are discussed.

AB - In nature, microorganisms are exposed to multiple stress factors in parallel. Here, we investigated the response of the model cyanobacterium Synechocystis sp. PCC 6803 to simultaneous iron limitation and osmotic stresses. Iron is a major limiting factor for bacterial and phytoplankton growth in most environments. Thus, bacterial iron homeostasis is tightly regulated. In Synechocystis, it is mediated mainly by the transcriptional regulator FurA and the iron-stress activated RNA 1 (IsaR1). IsaR1 is an important riboregulator that affects the acclimation of the photosynthetic apparatus to iron starvation in multiple ways. Upon increases in salinity, Synechocystis responds by accumulating the compatible solute glucosylglycerol (GG). We show that IsaR1 overexpression causes a reduction in the de novo GG synthesis rate upon salt shock. We verified the direct interaction between IsaR1 and the 5'UTR of the ggpS mRNA, which in turn drastically reduced the de novo synthesis of the key enzyme for GG synthesis, glucosylglycerol phosphate synthase (GgpS). Thus, IsaR1 specifically interferes with the salt acclimation process in Synechocystis, in addition to its primary regulatory function. Moreover, the salt-stimulated GgpS production became reduced under parallel iron limitation in WT - an effect which is, however, attenuated in an isaR1 deletion strain. Hence, IsaR1 is involved in the integration of the responses to different environmental perturbations and slows the osmotic adaptation process in cells suffering from parallel iron starvation. PMID- 29468840 TI - Surface Oxidation of AuNi Heterodimers to Achieve High Activities toward Hydrogen/Oxygen Evolution and Oxygen Reduction Reactions. AB - Although much attention has been paid to the exploration of highly active electrocatalysts, especially catalysts for hydrogen evolution reaction (HER), oxygen evolution reaction (OER) and oxygen reduction reaction (ORR), the development of multifunctional catalysts remains a challenge. Here, we utilize AuNi heterodimers as the starting materials to achieve high activities toward HER, OER and ORR. The HER and ORR activities in an alkali environment are similar to those of Pt catalysts, and the OER activity is very high and better than that of commercial IrO2 . Both the experimental and calculated results suggest that the surface oxidation under oxidative conditions is the main reason for the different activities. The NiO/Ni interface which exists in the as-synthesized heterodimers contributes to high HER activity, the Ni(OH)2 -Ni-Au interface and the surface Ni(OH)2 obtained in electrochemical conditons gives rise to promising ORR and OER activities, respectively. As a comparison, a Au@Ni core-shell structure is also synthesized and examined. The core-shell structure shows lower activities for HER and OER than the heterodimers, and reduces O2 selectively to H2 O2 . The work here allows for the development of a method to design multifunctional catalysts via the partial oxidation of a metal surface to create different active centers.

AB - Osimertinib is a potent, highly selective, irreversible inhibitor of epidermal growth factor receptor (EGFR) and T790M resistance mutation. In vitro metabolism data suggested osimertinib is a substrate of cytochrome P450 (CYP)3A4/5, a weak inducer of CYP3A, and an inhibitor of breast cancer resistance protein (BCRP). A combination of in vitro data, clinical pharmacokinetic data, and drug-drug interaction (DDI) data of osimertinib in oncology patients were used to develop the physiologically based pharmacokinetic (PBPK) model and verify the DDI data of osimertinib. The model predicted the observed monotherapy concentration profile of osimertinib within 1.1-fold, and showed good predictability (within 1.7-fold) to the observed peak plasma concentration (Cmax ) and area under the curve (AUC) DDI ratio changes, when co-administered with rifampicin, itraconazole, and simvastatin, but not with rosuvastatin. Based on observed clinical data and PBPK simulations, the recommended dose of osimertinib when dosed with strong CYP3A inducers is 160 mg once daily. PBPK modeling suggested no dose adjustment with moderate and weak CYP3A inducers. PMID- 29468842 TI - Shielding verification and neutron dose evaluation of the Mevion S250 proton therapy unit. AB - For passive scattering proton therapy systems, neutron contamination is the main concern both from an occupational and patient safety perspective. The Mevion S250 compact proton therapy system is the first of its kind, offering an in-room cyclotron design which prompts more concern for shielding assessment. The purpose of this study was to accomplish an in-depth evaluation of both the shielding design and in-room neutron production at our facility using both Monte Carlo simulation and measurement. We found that the shielding in place at our facility is adequate, with simulated annual neutron ambient dose equivalents at 30 cm outside wall/door perimeter ranging from background to 0.07 mSv and measured dose equivalents ranging from background to 0.06 mSv. The in-room measurements reveal that the H*/D decreases when the distance from isocenter and field size increases. Furthermore, the H*/D generally increases when the angle around isocenter increases. Our results from in-room measurements show consistent trends with our Monte Carlo model of the Mevion system.

AB - SCOPE: The molecular mechanisms whereby gallates in green tea exert metabolic effects are poorly understood. METHODS AND RESULTS: We found that GPRC6A, a multi ligand-sensing G-protein-coupled receptor that regulates energy metabolism, sex hormone production, and prostate cancer progression, is a target for gallates. Sodium gallate (SG), gallic acid (GA) > ethyl gallate (EG) > octyl gallate (OG) dose dependently activated ERK in HEK-293 cells transfected with GPRC6A but not in non-transfected controls. SG also stimulated insulin secretion in beta-cells isolated from wild-type mice similar to the endogenous GPRC6A ligands, osteocalcin (Ocn) and testosterone (T). Side-chain additions to create OG resulted in loss of GPRC6A agonist activity. Another component of green tea, epigallocatechin 3-gallate (EGCG), dose-dependently inhibited Ocn activation of GPRC6A in HEK-293 cells transfected with GPRC6A and blocked the effect of Ocn in stimulating glucose production in CH10T1/2 cells. Using structural models of the venus fly trap (VFT) and 7-transmembrane (7-TM) domains of GPRC6A, calculations suggest that l-amino acids and GA bind to the VFT, whereas EGCG is calculated to bind to sites in both the VFT and 7-TM. CONCLUSION: GA and EGCG have offsetting agonist and antagonist effects on GPRC6A that may account for the variable metabolic effect of green tea consumption.

PMID- 29468844 TI - Are Older Adults With Symptomatic Knee Osteoarthritis Less Active Than the General Population? Analysis From the Osteoarthritis Initiative and the National Health and Nutrition Examination Survey. AB - OBJECTIVE: To compare objectively measured physical activity in older adults with symptomatic knee osteoarthritis (OA) with similarly aged adults without osteoarthritis (OA) or knee symptoms from the general population. METHODS: We included people ages 50-85 years with symptomatic knee OA from the Osteoarthritis Initiative (OAI, n = 491), and ages 50-85 years from the general population using National Health and Nutrition Examination Survey (NHANES, n = 449) data. A uniaxial accelerometer was worn for >=10 hours/day for >=4 days in the NHANES group in 2003-2004 and in the OAI group in 2008-2010. We calculated time spent in moderate-to-vigorous physical activity (MVPA in minutes/day) and described differences in MVPA and demographic variables between the samples. We conducted matched-pairs sensitivity analyses to further evaluate the role of potential confounders. RESULTS: Both cohorts had similarly low levels of physical activity in age- and sex-specific strata. Time in MVPA ranged from a median of 1-22 minutes/day in people with symptomatic knee OA, and from 1-24 minutes/day in the general population without OA or knee pain. These results were similar in sensitivity analyses. CONCLUSION: Time spent in MVPA was similarly low in those with symptomatic knee OA as in older adults without knee pain or OA.

AB - A few decades ago, the chances of survival for patients with a haematological malignancy needing Intensive Care Unit (ICU) support were minimal. As a consequence, ICU admission policy was cautious. We hypothesized that the long term outcome of patients with a haematological malignancy admitted to the ICU has improved in recent years. Furthermore, our objective was to evaluate the predictive value of the Acute Physiology and Chronic Health Evaluation (APACHE) II score. A total of 1095 patients from 5 Dutch university hospitals were included from 2003 until 2015. We studied the prevalence of patients' characteristics over time. By using annual odds ratios, we analysed which patients' characteristics could have had influenced possible trends in time. A approximated mortality rate was compared with the ICU mortality rate, to study the predictive value of the APACHE II score. Overall one-year mortality was 62%. The annual decrease in one-year mortality was 7%, whereas the APACHE II score increased over time. Decreased mortality rates were particularly observed in high risk patients (acute myeloid leukaemia, old age, low platelet count, bleeding as admission reason and need for mechanical ventilation within 24 h of ICU admission). Furthermore, the APACHE II score overestimates mortality in this patient category. PMID- 29468849 TI - Antiviral activities of Clinacanthus nutans (Burm.f.) Lindau extract against Cyprinid herpesvirus 3 in koi (Cyprinus carpio koi). AB - Cyprinid herpesvirus 3 (CyHV-3) or koi herpesvirus (KHV) is a virulent viral infection in common carp and koi. The disease has caused global epizootic and economic loss in fish aquaculture and in the wild. Clinacanthus nutans (Burm. f.) Lindau is a well-known medicinal plant used in Thai traditional medicine. Virucidal effects of the plant extract against human herpes simplex virus have been reported. In this study, C. nutans crude extract was tested for antiviral activities against CyHV-3 in koi carp. Results showed effective antiviral activity against CyHV-3 pre- and post-infection. The 50% lethal concentration (LC50 ) of extract was higher than 5 mg/ml. The 50% effective dose (ED50 ) was 0.99 mg/ml, 0.78 mg/ml, 0.75 mg/ml and 0.71 mg/ml at 1, 2, 3 and 4 hr pre infection, respectively. The ED50 from post-infection tests was 2.05 mg/ml and 2.34 mg/ml at 0 and 24 hr, respectively. These results demonstrated that crude extract expressed antiviral activity against CyHV-3 and can be applied as a therapeutic agent in common carp and koi aquaculture.

AB - Dermatofibrosarcoma protuberans (DFSP) is a rare soft tissue tumor that arises primarily on the trunk and extremities but seldom on the scalp. Several variants of DFSP have been described, including myxoid DFSP. Although typical DFSP may have focally myxoid areas, myxoid DFSP, in which most of the stroma is myxoid, is rare and can pose diagnostic challenges. Here, we report a case of myxoid DFSP with an unusual clinical presentation that could have been mistaken for a lipoma. Additionally, the myxoid DFSP displayed prominent vasculature in a myxoid stroma, which could have been mistaken for a myxoid liposarcoma. PMID- 29468851 TI - Isolates from Alpinia officinarum Hance attenuate LPS-induced inflammation in HepG2: Evidence from in silico and in vitro studies. AB - In an attempt to connect the legacy of centuries of invaluable knowledge from traditional medicine and the current understanding to the molecular mechanism of diseases, we took the advantage of the emergence of in silico screening as a promising tool for identification of potential leads from libraries of natural products. Traditional Chinese Medicine database was subjected to structure based virtual screening for identification of anti-inflammatory compounds using the 3D crystal structure of p38 alpha mitogen activated protein kinase. The molecular docking studies revealed the potential activity of several classes of compounds known to be the constituents of the rhizomes of Alpinia officinarum Hance (Lesser galangal). Five compounds, galangin, kaempferide, isorhamnetin, and two diarylheptanoids, were isolated from the rhizomes of the plant using vacuum liquid chromatography and flash chromatography techniques. The anti-inflammatory activity of these compounds was investigated on HepG2 cells stimulated by lipopolysaccharide. The latter induced the gene expression of proinflammatory cytokines; interleukin-1beta, interleukin-6, tumor necrosis factor alpha. Addition of the 5 isolated compounds downregulated this increased gene expression in a dose dependent manner. Thus, these results indicate that the isolated compounds from A. officinarum could be used as a beneficial source for preventing and treating inflammatory diseases. PMID- 29468852 TI - Dye-Incorporated Polynaphthalenediimide Acceptor for Additive-Free High Performance All-Polymer Solar Cells. AB - All-polymer solar cells (all-PSCs) can offer unique advantages for applications in flexible devices, and naphthalene diimide (NDI)-based polymer acceptors are the widely used polymer acceptors. However, their power conversion efficiency (PCE) still lags behind that of state-of-the-art polymer solar cells, due to low light absorption, suboptimal energy levels and the strong aggregation of the NDI based polymer acceptor. Herein, a rhodanine-based dye molecule was introduced into the NDI-based polymer acceptor by simple random copolymerization and showed an improved light absorption coefficient, an up-shifted lowest unoccupied molecular orbital level and reduced crystallization. Consequently, additive-free all-PSCs demonstrated a high PCE of 8.13 %, which is one of the highest performance characteristics reported for all-PSCs to date. These results indicate that incorporating a dye into the n-type polymer gives insight into the precise design of high-performance polymer acceptors for all-PSCs. PMID- 29468853 TI - The effect of hydroxyapatite nanoparticles on adipogenic differentiation of human mesenchymal stem cells. AB - Due to its excellent biocompatibility, nanosized hydroxyapatite (nHA) has drawn much attention for various applications in biomedical fields. There are growing concerns about its biosecurity; however, little is known about its effects on adipogenesis. In the present study, nHA with three different sizes were synthesized, and the in vitro effects of nHA on cell proliferation and adipogenic differentiation of human mesenchymal stem cells (hMSCs) were investigated. The results clearly show that nHA does not affect the cell viability, the lipids droplets formation, triglyceride (TG) synthesis, and the expression of adipogenic marker genes/proteins of hMSCs at concentrations lower than 50 MUg/mL. It is concluded that the adipogenic differentiation potential of hMSCs is not affected by nHA at noncytotoxic concentrations. These will provide a reference for the applications of nHA in biomedical fields. (c) 2018 Wiley Periodicals, Inc. J Biomed Mater Res Part A: 106A: 1822-1831, 2018. PMID- 29468854 TI - Differential effects of oxycodone and venlafaxine on resting state functional connectivity-A randomized placebo-controlled magnetic resonance imaging study. AB - AIM: Different mechanisms may be involved in the antinociceptive effects of oxycodone (opioid) and venlafaxine (serotonin-norepinephrine reuptake inhibitor), and the aim of this study was to investigate the effect of these drugs on brain functional connectivity. METHODS: Resting state functional magnetic resonance imaging was acquired in 20 healthy volunteers before and after a 5-day treatment with oxycodone, venlafaxine, or placebo in a randomized, double-blind, crossover study. Functional connectivity analyses were performed between four predefined seeds (dorsal anterior cingulate cortex, rostral anterior cingulate cortex, posterior insula, and prefrontal cortex), and the whole brain. RESULTS: The overall interpretation was that there were differences between the effects of oxycodone and venlafaxine on functional connectivity. Oxycodone mainly showed decreased functional connectivity between limbic structures and to supralimbic areas (all P < 0.05). Venlafaxine also showed decreased functional connectivity between limbic structures and to supralimbic areas, but increased functional connectivity to structures in the midbrain and brain stem was also found (all P < 0.05). CONCLUSIONS: Oxycodone and venlafaxine showed differential effects on resting-state functional connectivity as compared to placebo. This supports that the two drugs exert different mechanisms, and that the drugs in combination may exert additive effects and could potentially improve pain therapy.

Chemotherapy is the mainstay treatment for ovarian cancer. Despite the initial response is promising, frequent recurrence in patients with advanced diseases remains a therapeutic challenge. Thus, understanding the biology of chemoresistance is of great importance to overcome this challenge and will conceivably benefit the survival of ovarian cancer patients. Although mechanisms underlying the development of chemoresistance are still ambiguous, accumulating evidence has supported an integral role of cancer stem cells (CSCs) in recurrence following chemotherapy. Recently, tumor metabolism has gained interest as a reason of chemoresistance in tumors and chemotherapeutic drugs in combination with metabolism targeting approaches has been found promising in overcoming therapeutic resistance. In this review, we will summarize recent studies on CSCs and metabolism in ovarian cancer and discuss possible role of CSCs metabolism in chemoresistance.

AB - The psychological and neuropsychological characteristics of gifted children andadolescents are analysed, as well as the emotional and behavioural risks linkedto this condition.A prospective follow-up study of N=93 highly gifted students suffering fromschool failure at the beginning of adolescence was implemented. They weretreated with an integrated form of music psychotherapy and verbal psychotherapyin 5 separate groups. The methodology of treatment combined active musicalimprovisation with the writing of stories or the production of drawings undermusical induction, followed by verbal elaboration in the cognitive psychodynamicpsychotherapeutic tradition.The evaluation was based on a mixed methods design, combining psychometricscales, projective tests and expressive tests. Comparative pretest-posttest,correlational and multidimensional analyses were computed, using non-parametricstatistical procedures adapted to small samples and data belonging to a mixedlevel of measurement. We present a meta analysis of the confirmatory results in5 subgroups.There was a significant increase in the capacity of concentration, the capacityof imaginary and symbolic elaboration, the pictorial and literary creativity,self-esteem, the quality of coping strategies, as well as in school marks. Therewas a significant decrease in defensive functioning and in embitterment andresignation. The latent dimensions extracted with Optimal Scaling proceduresfrom the correlational matrixes of the Delta values of TAT and TSD-Z weremeaningful at the light of the state-of-the arts.The results of the study confirm a prior theoretical modelization coming out ofthe preparatory stage of the research project.

AB - Development of efficient electrocatalysts for oxygen evolution reaction (OER) is of great significance for future renewable energy applications. Herein, efficient OER electrocatalysts based on iron hydroxide-modified nickel hydroxylphosphate (NiPO/Fe(OH) x) single-wall nanotubes (SWNTs) have been prepared by a facile stepwise surfactant-free solvothermal strategy, which possess diameters of about 6 nm and lengths of about several micrometers. Benefiting from the synergistic effect between iron hydroxides and NiPO SWNTs, the as-prepared NiPO/Fe(OH) x SWNTs exhibit higher OER activity than primary NiPO SWNTs. Furthermore, the OER activity with different Fe contents displays a volcano-type shape, and the optimized NiPO/Fe(OH) x SWNTs present excellent activity with a low overpotential of 248 mV to deliver a current density of 10 mA cm-2 and 323 mV to achieve a large current density of 100 mA cm-2, as well as a remarkably low Tafel slope of 45.4 mV dec-1 in 1 M KOH electrolyte. The present work provides valuable insights to improve the OER performance by rational surface modification. PMID- 29468866 TI - Quantifying the Degree of Aggregation from Fluorescent Dye-Conjugated DNA Probe by Single Molecule Photobleaching Technology for the Ultrasensitive Detection of Adenosine. AB - In this work, we demonstrated a single molecule photobleaching-based strategy for the ultrasensitive detection of adenosine. A modified split aptamer was designed to specifically recognize individual adenosine molecules in solution. The specific binding of dye-labeled short strand DNA probes onto the elongated aptamer strand in the presence of adenosine resulted in a concentration-dependent self-aggregation process. The degree-of-aggregation (DOA) of the short DNA probes on the elongated aptamer strand could then be accurately determined based on the single molecule photobleaching measurement. Through statistically analyzing the DOA under different target concentrations, a well-defined curvilinear relationship between the DOA and target molecule concentration (e.g., adenosine) was established. The limit-of-detection (LOD) is down to 44.5 pM, which is lower than those recently reported results with fluorescence-based analysis. Owing to the high sensitivity and excellent selectivity, the sensing strategy described herein would find broad applications in biomolecule analysis under complicated surroundings. PMID- 29468867 TI - Simple and Sensitive Method for Determination of Protein Kinase Activity Based on Surface Charge Change of Peptide-Modified Gold Nanoparticles As Substrates. AB - Protein tyrosine kinases play a pivotal role in intracellular signal transduction pathways and oncogenic transformation. It is necessary to develop a simple, cost effective, and sensitive kinase assay for study of protein kinases and discovery of kinase-target drugs. In this paper, we present a simple and sensitive method for homogeneous detection of protein kinase activity and screening of inhibitor by measuring surface charge change on the peptide-modified gold nanoparticles (GNPs) as kinase substrates. In this assay, Abl (Abelson murine leukemia viral oncogene) kinase was used as a model. In the presence of Abl kinase and ATP, the surface negative charge on GNPs significantly increases due to phosphorylation of the peptide-modified GNPs. The surface charge on the peptide-modified GNPs was measured by zeta potential analyzer. Under the optimum conditions, the zeta potential on the peptide-modified GNPs was linearly dependent on Abl kinase concentration, the linear range was from 1 to 40 nM and the detection limit was 1 nM. This method was used to evaluate the inhibition efficiency of inhibitors, and the obtained IC50 values were well in agreement with the results reported in the references. Furthermore, this method was successfully applied to determine Abl kinase activity in the cell lysates. Compared to current methods, this new method shows simplicity, short analysis time, high sensitivity, and will become a promising platform for kinase-related fundamental research and inhibitor screening. PMID- 29468868 TI - B-Site Cation-Ordered Double-Perovskite Oxide as an Outstanding Electrode Material for Supercapacitive Energy Storage Based on the Anion Intercalation Mechanism. AB - Perovskite oxides are highly promising electrodes for oxygen-ion-intercalation type supercapacitors owing to their high oxygen vacancy concentration, oxygen diffusion rate, and tap density. Based on the anion intercalation mechanism, the capacitance is contributed by surface redox reactions and oxygen ion intercalation in the bulk materials. A high concentration of oxygen vacancies is needed because it is the main charge carrier. In this study, we propose a B-site cation-ordered Ba2Bi0.1Sc0.2Co1.7O6-delta as an electrode material with an extremely high oxygen vacancy concentration and oxygen diffusion rate. A maximum capacitance of 1050 F g-1 was achieved, and a high capacitance of 780 F g-1 was maintained even after 3000 charge-discharge cycles at a current density of 1 A g 1 with an aqueous alkaline solution (6 M KOH) electrolyte, indicating an excellent cycling stability. In addition, the specific volumetric capacitance of Ba2Bi0.1Sc0.2Co1.7O6-delta reaches up to 2549.4 F cm-3 based on the dense construction and high tap density (3.2 g cm-3). In addition, an asymmetric supercapacitor was constructed using activated carbon as a negative electrode, and it displayed the highest specific energy density of 70 Wh kg-1 at the power density of 787 W kg-1 in this study. PMID- 29468869 TI - Nonvolatile Electric Double-Layer Transistor Memory Devices Embedded with Au Nanoparticles. AB - We present nonvolatile transistor memory devices that rely on the formation of electric double layer (EDL) at the semiconductor-electrolyte interface. The two critical functional components of the devices are the ion gel electrolyte and gold nanoparticles (NPs). The ion gel electrolyte contains ionic species for EDL formation that allow inducing charges in the semiconductor-electrolyte interface. The gold NPs inserted between the ion gel and the channel layer serve as trapping sites to the induced charges to store the electrical input signals. Two different types of gold NPs were used: one prepared using direct thermal evaporation and the other prepared using a colloidal process. The organic ligands attached onto the colloidal gold NPs prevented the escape of the trapped charges from the particles and thus enhanced the retention characteristics of the programmed/erased signals. The low-voltage-driven EDL formation resulted in a programmed/erased memory signal ratio larger than 103 from the nonvolatile indium gallium-zinc oxide transistor memory devices at voltages below 10 V, which could be held for >105 s. The utility of the electrolytes to operate memory devices demonstrated herein should provide an alternative strategy to realize cheap, portable electronic devices powered with thin-film batteries. PMID- 29468870 TI - Phase-Change Partitions for Thermal Automation of Multistep Reactions. AB - Medical diagnostics and basic research in low-resource settings require automated reactions to be controlled in a simple, portable manner. Here, we present a novel platform that enables simple automation of multistep reactions to facilitate robust, hands-free assay operation without complex microfluidics or paperfluidics. We separate reagent zones in a conventional PCR tube via solid layers of purified higher alkanes. Reagents can be mixed on demand by simply raising the temperature above the melting point of the alkane partition that separates the two zones. We partitioned various reagents to enable hands-free thermally automated isothermal nucleic acid amplification, heavy metal ion detection, and beta-lactamase detection with tandem antibiotic specificity characterization. We anticipate that this phase-change partition platform will find broad application in clinical diagnostics at the point-of-care and in low resource settings. PMID- 29468871 TI - Peptide Probe for Multiwalled Carbon Nanotubes: Electrophoretic Assessment of the Binding Interface and Evaluation of Surface Functionalization. AB - Noncovalent interactions of peptides and proteins with carbon nanotubes play a key role in sensing, dispersion, and biocompatibility. Advances in these areas require that the forces which contribute to physical adsorption are understood in order that the carbon nanotubes present a degree of functionalization appropriate to the desired application. Affinity analyses of peptides are employed to evaluate the role of tryptophan and arginine residues in physical adsorption to carboxylated multiwalled carbon nanotubes. Peptides containing arginine and tryptophan, WR(W) n, are used with affinity capillary electrophoresis to identify factors that lead to the formation of peptide-carbon nanotube complexes. The effects of changing the amino acid composition and residue length are evaluated by measuring dissociation constants. Electrostatic interactions contribute significantly to complexation, with the strongest interaction observed using the peptide WRWWWW and carboxylated carbon nanotube. Stronger interaction is observed when the tryptophan content is successively increased as follows: WR(W)4 > WR(W)3 > WR(W)2 > WRW > WR. However, as observed with polytryptophan (W5, W4, W3, and W2), removing the arginine residue significantly reduces the interaction with carbon nanotubes. Increasing the arginine content to WRWWRW does not improve binding, whereas replacing the arginine residue in WRWWWW with lysine (WKWWWW) reveals that lysine also contributes to surface adsorption, but not as effectively as arginine. These observations are used to guide a search of the primary sequence of lysozyme to identify short regions in the peptide that contain a single cationic residue and two aromatic residues. One candidate peptide sequence (WMCLAKW) from this search is analyzed by capillary electrophoresis. The dissociation constant of carboxylated multiwalled carbon nanotubes is measured for the peptide, WMCLAKW, to demonstrate the utility of affinity capillary electrophoresis analysis. PMID- 29468873 TI - Quantitative Analysis of the Incorporation Behaviors of Sr and Ti Atoms During the Atomic Layer Deposition of SrTiO3 Thin Films. AB - The atomic layer deposition (ALD) of multication oxide films is complicated because the deposition behaviors of the component oxides are not independent of one another. In this study, the Ti and Sr atom incorporation behaviors during the ALD of SrTiO3 films were quantitatively examined via the carefully designed ALD process sequences. H2O and O3 were adopted as the oxygen sources of the SrO subcycles, whereas only O3 was used for the TiO2 ALD subcycles. Apart from the general conjecture on the roles of the different types of oxygen sources, the oxygen source that was adopted for the subcycles of the other component oxide had almost complete control of the metal atom incorporation behaviors. This means that the first half-cycle of ALD played a dominant role in determining the metal incorporation rate, which revealed the critical role of the steric hindrance effect during the metal precursor injection for the ALD rate. O3 had almost doubled its reactivity toward the Ti and Sr precursors compared with H2O. Although these are the expected results from the common knowledge on ALD, the quantitative analysis of the incorporation behaviors of each metal atom provided insightful viewpoints for the ALD process of this technically important oxide material. Furthermore, the SrTiO3 films with a bulk dielectric constant as high as 236 were obtained by the Ru-SrTiO3-RuO2 capacitor structure. PMID- 29468872 TI - Quest for Efficacious Next-Generation Taxoid Anticancer Agents and Their Tumor Targeted Delivery. AB - Paclitaxel and docetaxel are among the most widely used chemotherapeutic drugs against various types of cancer. However, these drugs cause undesirable side effects as well as drug resistance. Therefore, it is essential to develop next generation taxoid anticancer agents with better pharmacological properties and improved activity especially against drug-resistant and metastatic cancers. The SAR studies by the authors have led to the development of numerous highly potent novel second- and third-generation taxoids with systematic modifications at the C 2, C-10, and C-3' positions. The third-generation taxoids showed virtually no difference in potency against drug-resistant and drug-sensitive cell lines. Some of the next-generation taxoids also exhibited excellent potency against cancer stem cells. This account summarizes concisely investigations into taxoids over 25 years based on a strong quest for the discovery and development of efficacious next-generation taxoids. Discussed herein are SAR studies on different types of taxoids, a common pharmacophore proposal for microtubule-stabilizing anticancer agents and its interesting history, the identification of the paclitaxel binding site and its bioactive conformation, characteristics of the next-generation taxoids in cancer cell biology, including new aspects of their mechanism of action, and the highly efficacious tumor-targeted drug delivery of potent next generation taxoids.

Understanding of the interactions between the effects of the shape of M-MSNs and CTCs is crucial to maximize the binding capacity and capture efficiency as well as to facilitate the sensitivity and efficiency of detection. In this work, fluorescent M-MSNs were rationally designed with sphere and rod morphologies while retaining their robust fluorescence and uniform surface functionality. After conjugation with the antibody of epithelial cell adhesion molecule (EpCAM), both of the differently shaped M-MSNs-EpCAM obtained achieved efficient enrichment of CTCs and fluorescent-based detection. Importantly, rodlike M-MSNs exhibited faster immunomagnetic isolation as well as better performance in the isolation and detection of CTCs in spiked cells and real clinical blood samples than those of their spherelike counterparts. Our results showed that shape engineering contributes positively toward immunomagnetic isolation, which might open new avenues to the rational design of magnetic-fluorescent nanoprobes for the sensitive and efficient isolation and detection of CTCs.

AB - The amphiphilic monomer 2-hydroxyethyl methacrylate (HEMA) is widely used in dental adhesives as a priming component, especially for dentin bonding. It behaves as a compatibilizer between hydrophilic and hydrophobic components and stabilizes the multicomponent adhesive system. However, there are several drawbacks associated with using HEMA, such as water retention within the adhesive layer, hydrolysis in oral environments, and cytotoxicity. These drawbacks lead to the failure of tooth restoration and represent a heavy medical burden. Thus, it is imperative to find a new compatibilizer to substitute for HEMA. Because of their superior compatibilization capabilities as functional solid surfactants, amphiphilic Janus particles are chosen as candidates for an alternative to HEMA in dental adhesives. Reactive amphiphilic Janus nanoparticles are synthesized by selectively etching and modifying at the interface of a Pickering emulsion. This approach could be extended to the synthesis of a series of other Janus nanoparticles. The Janus nanoparticles were verified to be better for the reduction of the phase separation and stabilization of dentin adhesives than HEMA. It is also demonstrated that these reactive Janus nanoparticles can strongly enhance the dentin bonding interface without cytotoxicity. It is clearly illustrated by this study that Janus nanoparticles may be promising materials to substitute for HEMA in dental adhesives.

AB - The ginsenoside 20- O-beta-glucopyranosyl-20( S)-protopanaxadiol, compound K, has attracted much attention in functional food, traditional medicine, and cosmetic industries because of diverse pharmaceutical activities. The effective production of compound K from ginseng extracts has been required. However, an enzyme capable of completely converting all protopanaxadiol (PPD)-type ginsenosides to compound K has not been reported until now. In this study, unlike other enzymes, beta glucosidase from Caldicellulosiruptor bescii was able to hydrolyze sugar moieties such as l-arabinofuranose as well as d-glucose and l-arabinopyranose as the C-20 outer sugar in ginsenosides. Thus, ginsenoside Rc containing l-arabinofuranose can be converted to compound K by only this enzyme. Under the optimized reaction conditions, the enzyme completely converted PPD-type ginsenosides in ginseng extracts to compound K with the highest productivity among the reported results. This is the first report of the enzyme capable of completely converting all PPD type ginsenosides into compound K. PMID- 29468878 TI - Identification of a Novel Esterase from Marine Environmental Genomic DNA Libraries and Its Application in Production of Free All- trans-Astaxanthin. AB - Astaxanthin is a pigment with various functions. Free astaxanthin is obtained mainly through saponification methods, which could result in many byproducts. Enzymatic methods using lipases have been used in a few cases, while there are no reports on the use of esterases for the production of free astaxanthin. Herein we present the screening and identification of a novel esterase (Est3-14) from a marine mud metagenomic library. Est3-14 is pH-sensitive and keeps good stability in alkaline buffers (residual activity 94%, pH 8.0, 4 degrees C, and 36 h). Meanwhile, Est3-14 keeps a good stability in the medium temperature condition (residual activity 56.7%, pH 8.0, 40 degrees C, and 84 h). Est3-14 displayed high hydrolysis activity to prepare free all- trans-astaxanthin in biphasic systems. Furthermore, under optimal conditions (0.5 mL ethanol, 6 mL 0.1 M Tris HCl buffer, pH 8.0, 0.5% (w/v) H. pluvialis oil, 40 degrees C), the hydrolytic conversion ratio was 99.3% after 36 h.

AB - Peroxynitrite (ONOO-), an extremely reactive nitrogen species (RNS), is implicated in diverse pathophysiological conditions, including cancer, neurodegenerative diseases, and inflammation. Sensing and imaging of ONOO- in living systems remains challenging due to the high autofluorescence and the limited light penetration depth. In this work, we developed a bioluminescent probe BP-PN, based on luciferase-luciferin pairs and the ONOO--responded group alpha-ketoamide, for highly sensitive detection and imaging of endogenous ONOO- in living cells and mice for the first time. Attributed to the BL without external excitation, the probe BP-PN exhibits a high signal-to-noise ratio with relatively low autofluorescence. Furthermore, we examine the application of the probe BP-PN using the mice model of inflammation, and BP-PN shows high sensitivity for imaging endogenous ONOO- in inflamed mice. This newly developed bioluminescent probe would be a potentially useful tool for in vivo imaging of ONOO- in wider physiological and pathological processes.

AB - Amphiphilic polymer nanospheres of poly(3-sulfopropyl methacrylate potassium salt co-styrene) [P(SPMA- co-St)] were prepared by a simple soap-free emulsion polymerization method and used as efficient water lubrication additives to enhance the antiwear behaviors of the Ti6Al4V alloy. The monodisperse and flexible P(SPMA- co-St) bicomponent copolymer nanospheres were synthesized with a controllable manner by adjusting the mass fraction ratio of the monomers, with the hydrophobic polystyrene (PSt) as the hard skeletal carrier component and the hydrophilic PSPMA with a hydration layer structure as the soft lubrication layer in the course of friction. The influences of the monomer concentration, the copolymer nanosphere additive content, the load, and the frequency of the friction conditions on their tribological properties were studied in detail, and a probable antiwear mechanism of the soft/hard-coupled copolymer nanospheres under water lubrication was also proposed. The results show that compared with pure PSt, the P(SPMA- co-St) polymer nanospheres exhibited better antiwear property as an additive for water lubrication, and the friction coefficient and the wear volume first decreased and then increased with the increase of the SPMA content, indicating that the hydrophilic SPMA has a significant effect on lubrication properties owing to its hydration performance. Furthermore, with the increase of polymer nanosphere concentration, the friction coefficient and wear amount also decreased to a stable and low value at a saturation concentration of 1 wt %. The flexible polymer nanospheres with a hydrophilic soft SPMA shell and a rigid PSt core exhibited good friction-reduction and antiwear performance as lubrication additives, indicating their promising and potential applications in water lubrication and biological lubrication.

AB - Realizing a strong coupling between spin and resonator is an important issue for scalable quantum computation in semiconductor systems. Benefiting from the advantages of a strong spin-orbit coupling strength and long coherence time, the Ge hut wire, which is proposed to be site-controlled grown for scalability, is considered to be a promising candidate to achieve this goal. Here we present a hybrid architecture in which an on-chip superconducting microwave resonator is coupled to the holes in a Ge quantum dot. The charge stability diagram can be obtained from the amplitude and phase responses of the resonator independently from the DC transport measurement. Furthermore, we estimate the hole-resonator coupling rate of gc/2pi = 148 MHz in the single quantum dot-resonator system and estimate the spin-resonator coupling rate gs/2pi to be in the range 2-4 MHz. We anticipate that strong coupling between hole spins and microwave photons in a Ge hut wire is feasible with optimized schemes in the future.

AB - Clinical Emotional Freedom Techniques (EFT) is an evidence-based treatment for depression and anxiety. The current study sought to elucidate the relationship between posttraumatic stress disorder (PTSD), depression, and anxiety in a nonclinical population. The sample (N = 81) comprised participants at five 2-day EFT workshops. All groups used an EFT protocol called Borrowing Benefits, in which the group facilitator works with a single client while other participants self-apply EFT. Participants were assessed on 9 specific conditions as well as on the breadth (Positive Symptom Total [PST]) and depth (General Symptom Index [GSI]) of psychological distress. Physical pain and addictive cravings were also assessed. Significant reductions were observed in all measures (P < .03). Associations between PST, GSI, and PTSD were significant (P < .026). Participants maintained all gains at 6-month follow-up (P < .02) with the exception of the Hostility subscale, while Cohen's d = 0.54 indicated a moderate treatment effect for PTSD. The relationship between psychological and physiological conditions identified in this study is consistent with that found in other studies. Group treatment is cost-effective and efficient, and the efficacy of EFT in groups indicates the utility of the Borrowing Benefits technique.

AB - Lippia alba, belonging to the Verbenaceae family, is one of the most commonly utilized medicinal plants in folk medicine. The allelopathic activity was assessed using seeds of Lactuca sativa (lettuce) and Allium cepa (onion) by assessing the growth of the radicle and hypocotyl. The tests showed allelopathic efficiency in inhibiting the growth of lettuce and onion seeds. The best results for allelopathic activity were presented by the dichloromethane (DCM) fraction of the fresh plant, which inhibited radicle (23.04-100% lettuce and 64.17-66.36% onion) and hypocotyl (16.77-100% lettuce and 65.10-69.43% onion) formation, and as well as the DCM fraction of the dry plant, which also inhibited radicle (30.74 82.83% lettuce and 63.50-93.67% onion) and hypocotyl (24.12-70% lettuce and 69.07 79.95% onion) formation. Based on these results, it was found that the aerial parts of L. alba are rich in bioactive substances, suggesting the possibility of using of L. alba as a natural herbicide.

AB - The present study aimed to evaluate the effects of a group music intervention in managing behavioral and psychological symptoms in Chinese elderly with dementia. This cluster randomized trial recruited 73 elderly participants with moderate dementia from 10 elderly residential homes and assigned them to the intervention ( n = 40) and control ( n = 33) group. The intervention included 16 half-hour sessions of music intervention with multi-sensory components over eight weeks and control group received standard care. Participants' levels of subjective moods and neuropsychiatric symptoms such as agitation, aberrant motor behaviors, dysphoria, and irritability were assessed at baseline, the 2nd, 4th, 6th, and the end of the intervention. Controlling for baseline outcomes, latent growth modeling revealed significant intervention effects for agitation ( B = -1.03, SE = 0.30, p < 0.01), aberrant motor behavior ( B = -1.80, SE = 0.66, p < 0.01), and dysphoria ( B = -0.79, SE = 0.36, p < 0.05), with the intervention group showing improvements compared to no substantial changes in the control group. There were no significant intervention effects on irritability or subjective mood ( p > 0.05). The music intervention showed significant reduction in the behavioral and psychological symptoms in Chinese elderly patients with dementia. Elderly homes could adopt this practical non-pharmacological intervention as a strategy to improve the well-being of the elderly. PMID- 29468886 TI - Protective Effect of Kolaviron on Cyclophosphamide-Induced Cardiac Toxicity in Rats. AB - BACKGROUND: Cyclophosphamide (CP) is a nitrogen mustard alkylating drug used for the treatment of chronic and acute malignant lymphomas, myeloma, leukemia, neuroblastoma, adenocarcinoma, retinoblastoma, breast carcinoma, and immunosuppressive therapy. Despite its vast therapeutic uses, it is known to cause severe cardiac toxicity. Kolaviron (KV), a Garcinia kola seed extract containing a mixture of flavonoids, is reputed for its antioxidant and membrane stabilizing properties. OBJECTIVE: This study investigated the protective effect of KV on CP-induced cardiotoxicity in rats. METHODS: Thirty rats were used, and they were divided into 6 groups of 5 rats each. Group I received 2 mL/kg propylene glycol orally for 14 days; group II received CP (50 mg/kg/d, intraperitoneally [i.p.]) for 3 days; groups III and IV received 200 and 400 mg/kg/d KV, respectively, orally for 14 days and groups V and VI were pretreated with 200 and 400 mg/kg/d KV, respectively, orally for 14 days followed by CP (50 mg/kg/d, i.p.) for 3 days. RESULTS: CP treatment resulted in a significantly lower food consumption and body weight in rats. The lactate dehydrogenase and creatine kinase enzymes in cardiac tissues of rats treated with CP were significantly higher. In cardiac tissues, 3-day doses of CP resulted in significantly higher heart weight, cardiac troponin I, myeloperoxidase, malondialdehyde, hydrogen peroxide and lower superoxide dismutase, catalase, glutathione peroxidase activities, and reduced glutathione levels. Histological examination of cardiac tissues showed sign of necrosis of myocardium after CP treatment. However, administration of KV at 200 and 400 mg/kg for 14 days prior to CP treatment, increase food consumption, body weight, and attenuates the biochemical and histological changes induced by CP. CONCLUSIONS: These results revealed that KV attenuates CP-induced cardiotoxicity by inhibiting oxidative stress and preserving the activity of antioxidant enzymes.

AB - Magnetic nanoparticles have properties that cause to apply them in cancer therapy and vehicles for the delivery of drugs such as 5FU, especially when they are modified with biocompatible copolymers. The aim of this study is to modify superparamagnetic iron oxide nanoparticles (SPIONPs) with PCL-PEG-PCL copolymers and then utilization of these nanoparticles for encapsulation of anticancer drug 5FU. The ring-opening polymerization (ROP) was used for the synthesis of PCL-PEG PCL copolymer by epsilon-caprolactone (PCL) and polyethylene glycol (PEG2000). We used the double emulsion method (water/oil/water) to prepare 5FU-encapsulated Fe3O4 magnetic nanoparticles modified with PCL-PEG-PCL copolymer. Chemical structure and magnetic properties of 5FU-loaded magnetic-polymer nanoparticles were investigated systematically by employing FT-IR, XRD, VSM and SEM techniques. In vitro release profile of 5FU-loaded NPs was also determined. The results showed that the encapsulation efficiency value for nanoparticles were 90%. Moreover, the release of 5FU is significantly higher at pH 5.8 compared to pH 7.4. Therefore, these nanoparticles have sustained release and can apply for cancer therapy. PMID- 29468890 TI - A systematic review of the traits and cognitions associated with use of and belief in complementary and alternative medicine (CAM). AB - Complementary and alternative medicine (CAM) use is widespread despite the controversy over its effectiveness. Although previous reviews have examined the demographics and attitudes of CAM users, there is no existing review on the traits or cognitions which characterise either CAM users or those who believe in CAM effectiveness. The current systematic review set out to address these gaps in the literature by applying a narrative synthesis. A bibliographic search and manual searches were undertaken and key authors were contacted. Twenty-three papers were selected. The trait openness to experience was positively associated with CAM use but not CAM belief. Absorption and various types of coping were also positively associated with CAM use and belief. No other trait was reliably associated with CAM use or belief. Intuitive thinking and ontological confusions were positively associated with belief in CAM effectiveness; intuitive thinking was also positively associated with CAM use. Studies researching cognitions in CAM use/belief were mostly on non-clinical samples, whilst studies on traits and CAM use/belief were mostly on patients. The quality of studies varied but unrepresentative samples, untested outcome measures and simplistic statistical analyses were the most common flaws. Traits and cognition might be important correlates of CAM use and also of faith in CAM.

PMID- 29468896 TI - Real-world evaluation of Hba1c, blood pressure, and weight loss among patients with type 2 diabetes mellitus treated with canagliflozin: an analysis of electronic medical records from a network of hospitals in Florida. AB - OBJECTIVE: Clinical trials and real-world studies reported that canagliflozin (CANA) improved HbA1c, blood pressure (BP), and weight in patients with type 2 diabetes mellitus (T2DM). This study examines if previous results hold regionally and within specific patient sub-groups. METHODS: Adults with T2DM and >=12 months of clinical activity before the first CANA prescription (index) were identified in electronic medical records (January 1, 2012-February 15, 2017) from a network of hospitals in Florida. Quality measures were described at baseline and 3, 6, 9, and 12 months post-index. Selected thresholds were HbA1c < 7%, BP < 140/90 mmHg, and weight loss >=5%. Sub-groups included patients >=65 years old, with African American race, with CANA dose increase, initiating CANA in an endocrinology setting, and initiating CANA in a primary care setting. RESULTS: Overall, 1,259 patients (mean age = 56.7 years; 51.2% female, 70.4% White) were identified. Among patients with a baseline HbA1c >= 7%, 16.1% had an HbA1c < 7% 3 months following CANA initiation, and the mean HbA1c decreased from 8.8% to 8.1%. Among patients with a baseline systolic BP >=140 mmHg or diastolic BP >= 90 mmHg, 59.3% attained a systolic BP < 140 mmHg and 77.3% a diastolic BP < 90 mmHg after 3 months. HbA1c and BP responses were sustained through 12 months. The proportion of patients with a weight loss from baseline >=5% increased from 17.0% at 3 months to 31.1% at 12 months. Consistent trends were observed for all sub-groups. CONCLUSIONS: In CANA-treated patients and patient sub-groups from a network of Florida hospitals, improvements in quality measures and response durability were similar to clinical trials and other real-world studies.

Despite its undeniable impact on patient's quality of life and daily care, there is a lack of evidence-based therapy on patients with this condition. METHODS: We surveyed physiotherapists working in nursing homes in Flanders (Belgium) concerning the use and perceived effect of therapeutic strategies and positioning methods/aids. RESULTS: Positioning and soft passive mobilization were the most applied and positively appraised therapeutic interventions. Highest ratings for positioning were found for C-shaped positioning cushions and multi-position wheelchair. According to the respondents, key points for paratonia approach were relaxation, positioning, active movement stimulation, and-to some extent-passive mobilization. Indispensable for any success however is multidisciplinary cooperation. CONCLUSION: These findings might provide an inspirational path for research to verify possible (evidence based) beneficial treatments that could be applied to improve current and future treatment of patients with paratonia.

PMID- 29468901 TI - Osteochondritis Dissecans of the Knee - Conservative Treatment Strategies: A Systematic Review. AB - Objective Osteochondritis dissecans (OCD) lesions are a relevant problem that affects the long-term prognosis of young patients. The purpose of this study was to analyze the evidence on potential and indications of nonsurgical treatment strategies for knee OCD. Design The search was conducted on 3 medical electronic databases according to PRISMA guidelines, including reports of any level of evidence dealing with the conservative management of knee OCD. Of 1688 identified records, 55 full-text articles were screened: 27 studies met the inclusion criteria, for a total of 908 knees, and were used for the analysis. Results No high-level studies were found: 24 articles were case series and 3 case reports, reporting on different treatments summarized in (1) restriction of physical activity, (2) physiokinesitherapy and muscle-strengthening exercises, (3) physical instrumental therapies, (4) limitation of weightbearing, and (5) immobilization. The analysis showed an overall healing rate of 61.4%, with large variability (10.4%-95.8%). A conservative treatment based on restriction of sport and strenuous activities seems a favorable approach, possibly combined with physiokinesitherapy. Negative prognostic factors were also identified: larger lesion size, more severe lesion stages, older age and skeletal maturity, discoid meniscus, and clinical presentation with swelling or locking. Conclusions The literature on conservative treatments for knee OCD is scarce. Among different non surgical treatment options, strenuous activity restriction seems a favorable approach, whereas there is no evidence that physical instrumental therapy, immobilization, or weightbearing limitation could be beneficial. However, further studies are needed to improve treatment potential and indications for the conservative management of knee OCD. PMID- 29468902 TI - Local Anesthetics' Toxicity toward Human Cultured Chondrocytes: A Comparative Study between Lidocaine, Bupivacaine, and Ropivacaine. AB - Objective In orthopedic joint injection, the most frequently used local anesthetics are ropivacaine, bupivacaine, and 1% or 2% lidocaine. The aim of this study was to examine effects of these various anesthetics on the viability of human chondrocytes. Our hypothesis was that all local anesthetics tested damage human chondrocytes in vitro. Methods Primary human chondrocytes were isolated and cultured from 6 donated human knee joints (mean age of donors 61.2 years). Local anesthetics were added to these cultures. Toxicity analysis was performed by visualization of cell structure using light microscopy. Determination of vital chondrocytes was performed by use of a Casy cell counter. Chondrocytes' cell death was examined by fluorescence microscopy and an XTT ELISA assay. Results Light microscope and fluorescence microscope data revealed a defect cell structure and increased number of dead cells after addition of 1% or 2% lidocaine and bupivacaine but not ropivacaine. We were able to show an increased level of XTT activity after treatment with bupivacaine, 2% lidocaine or ropivacaine. The count of vital chondrocytes was significantly decreased after treatment with bupivacaine, 1% or 2% lidocaine, and ropivacaine. Conclusions The data show that treatment with local anesthetics induces cell damage of human chondrocytes in vitro. Ropivacaine seems to be a local anesthetic with the lowest toxic potential on human chondrocytes, a feature that may favor its preference for use in joint injection.

AB - A new benzofuran, methyl (2S,2"S,3'E)-[2-(1"-acetoxypropan-2-yl)-2,3 dihydrobenzofuran-5-yl]acrylate (1), and 13 known compounds (2-14) were isolated from an ethanol extract of Artemisia halodendron Turcz. ex Bess. The chemical structures of these compounds were determined by 1D and 2D NMR (1H-1H COSY, HMBC, HMQC and NOESY) and HR-ESI-MS spectra, and results were compared with data from the literature. The effects of compounds 1-14 were measured on NF-kappaB activation, with compounds 2 and 3 exhibiting inhibitory activities against TNF alpha-induced NF-kappaB reporter gene expression in HeLa cells from 10 to 100 MUM. PMID- 29468904 TI - The experiences of general practitioner partners living with distress: An interpretative phenomenological analysis. AB - Doctors, including general practitioners, experience higher levels of mental illness than the general population. General practitioners who are partners in their practices may face heightened stress. In total, 10 general practitioner partners living with work-related distress were interviewed, and transcripts were analysed using interpretative phenomenological analysis. Three major themes arose: (1) extreme distress, (2) conflicted doctor identity and (3) toxic versus supportive workplace relationships. Participants detailed symptoms of depression, anxiety and burnout; reported conflicted identities; and discussed the impact of bullying partnerships. We recommend that organisational interventions tackling issues such as bullying be implemented and opportunities to debrief be offered as protected time activities to general practitioner partners. PMID- 29468905 TI - The effect of viewing fitness imagery on body dissatisfaction: sex and physical activity differences. AB - Exposure to cultural bodily ideals featuring thinness and muscularity can have deleterious effects on body satisfaction. The current study explores the effect of exposure to such imagery on body dissatisfaction and the influence of internalisation of cultural and athletic ideals. 188 (97 male) adults (18-25yrs; M = 20.97) were grouped according to a 2 * 2 * 2 mixed between-within subjects design (male/female; high/low physical activity; intervention/control). Participants were exposed to images of idealised physiques or neutral images. Internalisation-general, sex, physical activity levels, and Body Mass Index were associated with baseline levels of body dissatisfaction. Internalisation of cultural ideals appears to be an important factor for the prediction of body dissatisfaction. Exposure to idealised images resulted in increases in body dissatisfaction across all groups compared to controls. Neither sex nor physical activity levels buffer young adults from the negative effects of viewing images featuring idealised bodies.

AB - Objective This study was performed to investigate the effects of age and sex on 10 salivary steroid hormones and analyze the correlations between salivary and plasma hormones. Methods The concentrations of 10 salivary steroid hormones in 1090 Chinese adult volunteers were examined using liquid chromatography-tandem mass spectrometry, and a related investigation was performed on the concentrations of salivary hormones in this population. Results The concentrations of androstenedione (A4), 17alpha-hydroxyprogesterone (17-OHP), aldosterone (ALD), cortisone (COR), corticosterone (CORT), cortisol (F), progesterone (P), and testosterone were significantly different between men and women (Student's t-test). Differences in 17-OHP and ALD concentrations were highly significant between women in the follicular and luteal phases of their menstrual cycle (Student's t-test). Five salivary steroid hormones (17-OHP, A4, CORT, COR, and F) significantly decreased with increasing age (Kruskal-Wallis test). A high linear correlation between salivary and plasma 17-OHP, P, A4, and F were observed with obvious sex-related differences (Pearson's correlation, r > 0.7). Conclusions Our results provide important knowledge regarding the descriptive characteristics of salivary hormones in relation to age and sex and their correlations with plasma hormones.

PMID- 29468908 TI - Inflammatory bowel disease and anemia: intravenous iron treatment. AB - OBJECTIVES: The main objective of our study was to determinate the effectiveness of intravenous iron treatment with ferric carboxymaltose in inflammatory bowel disease (IBD) patients. Our other objectives were to study parameters that would predict a good response to the treatment and to chart out possible side-effects of the treatment. MATERIALS AND METHODS: In our retrospective chart review study we collected clinical data and laboratory results related to IBD from medical records of 87 IBD patients who were treated with ferric carboxymaltose in Helsinki University Hospital between 2014 and 2016. RESULTS: The mean increase in hemoglobin levels of the patients was 24.6 g/l (+ 24%) after one month, 27.6 g/l (+ 27%) after three months and 26.0 g/l (+ 27%) after six months. Nine out of 87 treated patients (10.3%) reported side-effects during the iron infusion. A linear regression model assessing the change in hemoglobin levels after six months demonstrated close correlation with transferrin receptor count (p = .004) and ferritin (p = .016) with an adjusted R square of 0.463. CONCLUSION: Ferric carboxymaltose was found to be an effective and well tolerated treatment for iron deficiency anemia in patients with IBD. The results of our study further strengthen the current knowledge of the effectiveness and safety of the treatment. PMID- 29468910 TI - Definitive re-irradiation using intensity-modulated radiation therapy in cancers of the head and neck, focusing on rare tumors. AB - PURPOSE: To analyze the outcomes following re-irradiation for local recurrence of rare head and neck tumors. MATERIAL AND METHODS: We retrospectively analyzed 11 patients who had received intensity-modulated radiation therapy (IMRT) for recurrent tumors in the head and neck except for laryngopharynx. RESULTS: Primary tumor sites included the maxillary sinus, nasal cavity, and external ear canal in six, three, and two patients, respectively. The median follow-up times were 13 (range, 3-54) months. The median survival time was 17 months with 1- and 2-year survival rates of 63.64 and 39.77%, respectively. Among 11 patients, five experienced local failure in the follow-up period. The 1- and 2-year local control rates were 58 and 47%, respectively. Patients who had received a radiation dose of >=3 Gy per fraction showed significantly better local control than those receiving less (p = .0419). One patient experienced Grade 3 facial pain as acute toxicity. Late toxicities included radiographic findings of partial central nervous system necrosis in three patients and Grade 3 osteonecrosis and Grade 3 facial nerve disorder in one patient. CONCLUSIONS: Re-irradiation of rare head and neck tumors using IMRT for loco-regional recurrence may be an acceptable treatment option. PMID- 29468911 TI - Reality of obesity paradox: Results of percutaneous coronary intervention in Middle Eastern patients. AB - Objective The aim of this study was to assess the baseline clinical characteristics, coronary angiographic features, and adverse cardiovascular events during hospitalization and at 1 year of follow-up in obese patients compared with overweight and normal/underweight patients. Methods A prospective, multicenter study of consecutive patients undergoing percutaneous coronary intervention was performed. Results Of 2425 enrolled patients, 699 (28.8%) were obese, 1178 (48.6%) were overweight, and 548 (22.6%) were normal/underweight. Obese patients were more likely to be female and to have a higher prevalence of diabetes, hypertension, hypercholesterolemia, or previous percutaneous coronary intervention. Acute coronary syndrome was the indication for percutaneous coronary intervention in 77.0% of obese, 76.4% of overweight, and 77.4% of normal/underweight patients. No significant differences in the prevalence of multi-vessel coronary artery disease or multi-vessel percutaneous coronary intervention were found among the three groups. Additionally, no significant differences were found in stent thrombosis, readmission bleeding rates, or cardiac mortality among the three groups during hospitalization, at 1 month, and at 1 year. Conclusion The major adverse cardiovascular event rate was the same among the three groups throughout the study period. Accordingly, body mass index is considered a weak risk factor for cardiovascular comorbidities in Arab Jordanian patients. PMID- 29468913 TI - The EPA-based Utrecht undergraduate clinical curriculum: Development and implementation. AB - AIM: As reports of the application of entrustable professional activities (EPAs) increase, not only for postgraduate but also for undergraduate medical education, there is a need for descriptions of what a UME curriculum with EPAs could look like. We provide such a description based on the experiences at University Medical Center Utrecht, the Netherlands, which can be used as an example by other curriculum developers. METHODS: In a three-year process, the UMC Utrecht Curriculum Committee developed a clinical workplace curriculum with an EPA structure, taking into account examples, such as the US Core EPAs for Entering Residency, and recommendations to integrate and increase the length of clerkships. RESULTS: In the resulting curriculum, operational from 2016, students train to be trusted with indirect supervision before graduation in five broad EPAs: the clinical consultation; general medical procedures; informing, advising and guiding patients and families; communicating and collaborating with colleagues; and extraordinary patient care. Each of these integrates smaller (nested) EPAs that receive focused training attention in integrated clerkships at various moments and must be signed off for entrustment with indirect supervision to complete the clerkship. DISCUSSION: The framework of EPAs went through many iterations before it was consolidated. Among the issues that required special attention was the application of a supervision levels scale for sign-off, the necessity to cover all relevant clinical content while not labeling too many small tasks each as a separate EPA, methods of EPA-focused assessment in the workplace and the creation of an e-portfolio model to serve assessment and entrustment. PMID- 29468914 TI - Methotrexate-induced lymphoproliferative disorders: regression matters. PMID- 29468912 TI - Hormone treatments in congestive heart failure. AB - The common ultimate pathological feature for all cardiovascular diseases, congestive heart failure (CHF), is now considered as one of the main public health burdens that is associated with grave implications. Neurohormonal systems play a critical role in cardiovascular homeostasis, pathophysiology, and cardiovascular diseases. Hormone treatments such as the newly invented dual acting drug valsartan/sacubitril are promising candidates for CHF, in addition to the conventional medications encompassing beta receptor blockers, angiotensin converting enzyme inhibitors, angiotensin receptor blockers, and mineralocorticoid receptor antagonists. Clinical trials also indicate that in CHF patients with low insulin-like growth factor-1 or low thyroid hormone levels, supplemental treatment with growth hormone or thyroid hormone seems to be cardioprotective; and in CHF patients with volume overload the vasopressin antagonists can relieve the symptoms superior to loop diuretics. Furthermore, a combination of selective glucocorticoid receptor agonist and mineralocorticoid receptor antagonist may be used in patients with diuretic resistance. Finally, the potential cardiovascular efficacy and safety of incretin-based therapies, testosterone or estrogen supplementation needs to be prudently evaluated in large scale clinical studies. In this review, we briefly discuss the therapeutic effects of several key hormones in CHF. PMID- 29468915 TI - Association between sarcopenia and erectile dysfunction in males with type II diabetes mellitus. AB - BACKGROUND: The prevalence rates for both sarcopenia and erectile dysfunction (ED) gradually increase in middle-aged and elderly diabetic male population and they impair physical functioning, sexual functioning, and quality of life. The aim of the present study was to evaluate the sarcopenia in patients with diabetic ED. METHODS: The study included 98 male patients with type II diabetes mellitus (DM) aged 18-80 years. Blood chemistry and hormone levels were obtained. The International Index of Erectile Function (IIEF-5) questionnaire was administered to the patients. The patients were divided into three groups according to the IIEF-5 score; a score of 5-10 points indicated severe ED, a score of 11-20 indicated moderate ED, and a score of 21-25 points indicated no ED. The muscle mass, handgrip strength, timed up and go test, upper mid-arm circumference, calf circumference, and body mass index were obtained. The statistical analysis was performed using MedCalc Statistical Software version 12.7.7. All parameters were compared between the three groups. RESULTS: Of 98 patients included in the study, 84 patients had severe sarcopenia, 13 had moderate sarcopenia, while only one patient had normal muscle mass. The mean age was 56.59 +/- 11.46 years. When patients were divided into three groups according to IIEF-5 score, 38 had severe ED, 39 had moderate ED, and 21 had no ED. There was a significant difference between the three groups in terms of handgrip strength, timed up and go test scores, upper mid-arm circumference, and calf circumference (p < .05 for all). CONCLUSIONS: Although muscle mass remains unchanged, muscle strength and physical performance decrease in diabetic ED patients. Diabetic patients with severe and moderate ED have lower muscle strength and physical performance. PMID- 29468916 TI - The safety of gliptins : updated data in 2018. AB - INTRODUCTION: Dipeptidyl peptidase-4 inhibitors (DPP-4is) are generally considered as glucose-lowering agents with a safe profile in type 2 diabetes. Areas covered: An updated review of recent safety data from randomised controlled trials, observational studies, meta-analyses, pharmacovigilance reports regarding alogliptin, linagliptin, saxagliptin, sitagliptin, and vildagliptin, with a special focus on risks of hypoglycemia, pancreatitis and pancreatic cancer, major cardiovascular events, hospitalisation for heart failure and other new safety issues, such as bone fractures and arthralgia. The safety of DPP-4i use in special populations, elderly patients, patients with renal impairment, liver disease or heart failure, will also be discussed. Expert opinion: The good tolerance/safety profile of DPP-4is has been largely confirmed, including in more fragile populations, with no gastrointestinal adverse effects and a minimal risk of hypoglycemia. DPP-4is appear to be associated with a small increased incidence of acute pancreatitis in placebo-controlled trials, although most observational studies are reassuring. Most recent studies with DPP-4is do not confirm the increased risk of hospitalisation for heart failure reported with saxagliptin in SAVOR-TIMI 53, but further post-marketing surveillance is still recommended. New adverse events have been reported such as arthralgia, yet a causal relationship remains unclear. PMID- 29468917 TI - The Acute Effects of Aerobic Exercise on Cognitive Flexibility and Task-Related Heart Rate Variability in Children With ADHD and Healthy Controls. AB - OBJECTIVE: To investigate cognitive flexibility and task-related heart rate variability following moderately intense aerobic exercise and after watching a video in both children with ADHD and healthy controls. METHOD: Using a cross-over design, participants completed cognitive assessments following exercise and a physically inactive control condition. Behavioral performance was assessed using the Alternate Uses task. Heart rate variability was recorded via electrocardiography during the cognitive task. RESULTS: The statistical analysis revealed that in comparison with the control condition, both groups showed higher cognitive flexibility following aerobic exercise. Moreover, decreased low frequency and high frequency power was observed in the exercise condition. CONCLUSION: The findings suggest that exercise elicits similar benefits for cognitive flexibility in children with ADHD and healthy controls, partly due to an increase in arousal induced by parasympathetic withdrawal. PMID- 29468918 TI - Relations Between Sleep and Temperament in Preschool Children With ADHD. AB - OBJECTIVE: The objective of this study was to assess the links between temperament and sleep in a group of preschoolers with ADHD. METHOD: Twenty-five ADHD ( M = 5.37 years, SD = 1.09) and 22 typically developing (TD; M = 5.10, SD = 1.18) preschoolers participated in the study. Sleep was assessed with the Sleep Disturbance Scale and wrist actigraphy. The Preschool Temperament and Character Inventory (PsTCI) was used to evaluate the child temperament. RESULTS: ADHD children showed a temperamental profile characterized by higher novelty seeking, lower persistence, self-directness, and cooperativeness and marginally lower harm avoidance (HA) compared with controls. HA was associated negatively to wakefulness after sleep onset and sleep fragmentation and positively with sleep efficiency and sleep time. Reward dependence was negatively associated with wake episode length. CONCLUSION: Sleep and temperament are correlated in preschoolers with ADHD and temperament might represent an intermediate endophenotype underlying the relation between ADHD and sleep disorders. PMID- 29468919 TI - Health-related quality of life in hearing-impaired adolescents and children. AB - OBJECTIVE: To evaluate health-related quality of life (HRQoL) in hearing-impaired adolescents and children and to compare it with that of hearing individuals. STUDY DESIGN AND SETTING: Hearing-impaired adolescents and children were recruited to the study during their annual control visit to the Hearing Clinic of Helsinki University Hospital. They filled in a HRQoL questionnaire, either the 16 dimensional 16D (adolescents aged 12-17 years) or the 17-dimensional 17D (children aged 7-11 years). The total HRQoL scores were compared with previously collected data, matched for age and gender, from adolescents and children without any known handicaps or illnesses. RESULTS: In total 50 adolescents and 50 children completed the questionnaire. Of the 16/17 dimensions of the HRQoL instrument, hearing and communication were affected the most. The total HRQoL scores were somewhat lower in adolescents and children with hearing impairment than in the general populations of age-matched peers (p < .001 for adolescents and .030 for children). CONCLUSIONS: HRQoL in hearing-impaired adolescents and children is only slightly worse than in hearing adolescents and children. SIGNIFICANCE: This study evaluates the impact of hearing loss on HRQoL to enhance the care of these children. PMID- 29468920 TI - Training medical students for the twenty-first century: Rationale and development of the Utrecht curriculum "CRU+". AB - AIM: The aim of this report, written for the 40th anniversary issue of Medical Teacher, is to document 20 years of development of the Utrecht undergraduate medical curriculum, as both to exhibit accountability and to inform the community of the process and choices that can be made in long-term curriculum development. METHODS: We used the SPICES model, created by Medical Teacher's Editor Ronald Harden and colleagues in 1984. RESULTS: The Utrecht six-year program, now called "CRU+", has many distinct features that were introduced, most of which are well documented. A limited selection includes * A new 3+3 years Bachelor-Master structure following the EU Bologna rules leading to MD registration for cohorts of about 300. * Horizontally integrated classroom teaching of basic sciences with clinical disciplines predominantly in groups of 12 and limited lectures. * Mandatory knowledge retention tests, retesting the clinically relevant core knowledge from block tests of semesters one through four. * Vertical integration not only linking clinical experience with background knowledge, but also exemplified by a stepwise increase in health care responsibilities throughout the curriculum. * A final year focussing on growth towards the level of a primary responsible physician in a 12-week sub-internship for a limited number of patients and beds, in a chosen specialty. The student is called a semi-physician in the clerkship of this transitional year to residency. * Teaching skills training for all medical graduates, an elective teaching rotation and various peer-teaching arrangements throughout the curriculum. * Integrated semi longitudinal clerkships with an assessment focus on entrustment decisions for Entrustable Professional Activities. CONCLUSION: UMC Utrecht has made a continuous attempt to both develop its medical curriculum and to study and report on its development in the literature, regarding new methods found and insights derived. UMC Utrecht will remain committed to developing training to meet twenty first century demands of medical graduates. PMID- 29468921 TI - Cross-species comparison of the metabolism and excretion of selexipag. AB - 1. The metabolism of the prostacyclin receptor agonist selexipag (NS-304; ACT 293987) and its active metabolite MRE-269 (ACT-333679) has been investigated in liver microsomes and hepatocytes of rats, dogs, and monkeys. MRE-269 formation is the main pathway of selexipag metabolism, irrespective of species. Some interspecies differences were evident for both compounds in terms of both metabolic turnover and metabolic profiles. The metabolism of MRE-269 was slower than that of selexipag in all three species. 2. The metabolism of selexipag was also studied in bile-duct-cannulated rats and dogs after a single oral and intravenous dose of [14C]selexipag. MRE-269 acyl glucuronide was found in both rat and dog bile. Internal acyl migration reactions of MRE-269 glucuronide were identified in an experiment with the synthetic standard MRE-6001. 3. MRE-269 was the major component in the faeces of rats and dogs. In ex vivo study using rat and dog faeces, selexipag hydrolysis to MRE-269 by the intestinal microflora is considered to be a contributory factor in rats and dogs. 4. A taurine conjugate of MRE-269 was identified in rat bile sample. Overall, selexipag was eliminated via multiple routes in animals, including hydrolysis, oxidative metabolism, conjugation, intestinal deconjugation, and gut flora metabolism. PMID- 29468922 TI - The impact of perceived discrimination on personality among Chinese migrant children: The moderating role of parental support. AB - BACKGROUND: Previous research has indicated that perceived discrimination has harmful effects on migrant children's physical, mental and behavioral health. However, little is known as to whether these harmful effects cumulate to impact on migrant children's personalities. AIMS: This study examines the effect of perceived discrimination on personality, as well as the moderating role of parental support in the discrimination-personality linkage. METHODS: A purposeful convenience sample of 215 migrant children in Beijing, China, completed a standardized questionnaire. RESULTS: Migrant children experienced a moderate level of perceived discrimination, with Form 8 students experiencing greater discrimination than lower grades and those with lower family incomes also experiencing greater discrimination than those with higher family incomes. Perceived discrimination significantly predicted neuroticism; parental support significantly predicted extraversion, openness, agreeableness and conscientiousness, but the moderating effect of parental support was only marginally significant for the relation between discrimination and conscientiousness. CONCLUSION: This study underlines the need for researchers and policy makers to pay more attention to the impact of perceived discrimination on migrant children's personality development. PMID- 29468923 TI - Reflux symptom index and reflux finding score in 91 asymptomatic volunteers. AB - BACKGROUND: The primary goal of this study was to investigating the symptoms, in addition to the reflux-related laryngopharynx inflammation performance of asymptomatic, volunteers, and verified the 'normal point'. METHODS: A total of 91 asymptomatic subjects were recruited for this cross-sectional study between March 2016 and September 2016. Participants completed the reflux symptom index (RSI) assessment and underwent laryngostroboscopic examination using a rigid endoscope. Their RFS were graded according to the laryngeal findings. The distribution and the relationship of the RSI and the RFS were analyzed. RESULTS: The mean RSI of individuals was 2.24 +/- 2.34 [95% confidence interval (CI) = 1.75, 2.72], and the mean RFS of individuals was 5.78 +/- 1.74 (95% CI = 5.42, 6.15). The Pearson product-moment correlation coefficient of the RSI and RFS scores was -0.084 (n = 91, p = .428). CONCLUSIONS: Asymptomatic people could present relatively high RFS scores, and no linear relationship existed between RSI and RFS. PMID- 29468924 TI - Emerging molecular target antagonists for the treatment of biliary tract cancer. AB - INTRODUCTION: Biliary tract cancers (BTCs) are a heterogeneous group of cancers, characterized by low incidence but poor prognosis. Even after complete surgical resection for early stage, relapse is frequent and the lack of effective treatments contributes to the dismal prognosis. To date, the only standard treatment in first-line is cisplatin/gemcitabine combination, whereas no standard in 2nd-line has been defined. Hence, the current goal is to better understand the biology of BTCs, discovering new treatment methods and improving clinical outcomes. Areas covered: The development of next-generation-sequencing has unveiled the picture of the molecular signatures characterizing BTCs, leading to the identification of actionable mutations in biomarker-driven clinical trials. In this review we will cover the genetic landscape of BTC, focusing on the efficacy of existing treatments. Furthermore, we will discuss emerging molecular targets and evaluate the findings of pre-clinical studies. Finally, the encouraging results of clinical trials involving targeted therapies or immunotherapy will be reviewed. Expert opinion: FGFR fusion rearrangements and IDH1 or IDH2 mutations are the most promising targeted treatments under evaluation. In addition, innovative trial design will allow to offer a chance for tailored medicine to infrequent subgroups of BTCs patients based on their molecular features rather than their histology. PMID- 29468925 TI - Self-Reported ADHD and Adult Health in the United States. AB - OBJECTIVE: Informed by a social determinants of health framework, we investigate the relationship between self-reported ADHD diagnosis status and adult health, and whether observed associations are attenuated by biomedical and socioeconomic factors. METHOD: Using 2007 National Health Interview Survey data ( N = 19,104), we present multivariate logistic regression analyses of associations between self reported ADHD diagnosis status and five adult health outcomes. RESULTS: ADHD diagnosis was significantly associated with higher odds of injury, physical health conditions, functional limitations, fair/poor health, and psychological distress in fully specified models (adjusted odds ratios [AORs] = 1.62-2.36). Inclusion of controls for exogenous demographic characteristics, psychiatric comorbidities and health behaviors, and adult social and economic statuses attenuated but did not eliminate observed associations between ADHD and poorer adult health. CONCLUSION: Research on adult health outcomes for those with ADHD should include consideration of the mechanisms by which a diagnosis of ADHD leads to cumulative social disadvantages that independently contribute to poorer health outcomes. PMID- 29468926 TI - Development and characterization of HBsAg-loaded Eudragit nanoparticles for effective colonic immunization. AB - The present study was undertaken with an aim to investigate the potential of targeting colonic mucosa following oral vaccine delivery to generate prophylactic humoral and mucosal immune response. In present study, response surface methodology (RSM) using the central composite design (CCD) was applied for optimization of process and composition to get uniform, stable reproducible eudragit nanoparticles suitable for targeting to colon. The optimized formulation had the composition of 173 MUg HBsAg, 250 mg polymers concentration (4:1 combination of Eudragit S-100 and L-100) and 2% w/v Polyvinyl alcohol (PVA) along with adjuvant Monophosphoryl lipid A (MPLA). Mean particle size of optimized nanoparticles was found to be 730.4 nm, entrapment efficiency (58.38%) and polydispersity index of 0.185. Fluorescent spectroscopy, differential scanning calorimetry, and antigen integrity by SDS-PAGE established that antigen structure was preserved during and after formulation development. In-vitro release studies in different intestinal pH concluded antigen release at mild alkaline conditions. Real time fluorescence animal imaging confirmed the effective absorption and distribution of NPs at colon resulted in improved immune response. Present study concludes that Eudragit nanoparticles offers strong potential in colon targeting of vaccines through oral immunization. PMID- 29468927 TI - Inducible Co-Stimulator (ICOS) as a potential therapeutic target for anti-cancer therapy. AB - INTRODUCTION: The recent success of checkpoint-inhibitors in cancer treatment paved the way for the development of new strategies of agonist and antagonist agents against B7 superfamily members. Inducible Co-Stimulator (ICOS), a co stimulatory receptor for T-cell enhancement, arouses interest. Areas covered: We performed an extensive literature search with PUBMED using the keywords 'ICOS' and 'cancer' to discuss its involvement in oncogenesis, its expression in different malignancies, and its targeting in relevant preclinical studies. We also searched the Clinicaltrials.gov database for recent updates on early phase clinical trials. Expert opinion: ICOS/ICOSL axis has a dual effect and might participate in anti-tumour T cell response as well as a pro-tumour response due to its connection with regulatory T-cells (Tregs) suppressive activity. Therefore, both antagonist and agonist antibodies might be of interest in the targeting ICOS/ICOSL pathway for cancer treatment. In preclinical studies, ICOS agonist monoclonal antibodies (mAbs) have shown to potentiate the effect of inhibitory checkpoint blockade. In contrast, antagonistic anti-ICOS mAbs could not only inhibit lymphoid tumour cells expressing ICOS, but also dampen immunosuppressive Tregs. Two agonist and one antagonist mAbs are evaluated in phase I/II trials. Efficacy, safety, and combination strategies with anti-ICOS agonist or antagonist have yet to be specified. PMID- 29468928 TI - The 'work of childhood': understanding school functioning in youth with chronic pain. AB - School is often cited as the 'work of childhood' and serves as an important site for child and adolescent development. Frequent school absences in children and adolescents with chronic pain are well documented; however, variables that may explain school impairment are not understood. The potential consequences of school impairment are extensive, as these children and adolescents are at great risk for achieving poor grades and sometimes require full-time homebound instruction. This, in turn, can have adverse effects on occupational and social functioning well into adulthood. The present review provides a summary of selected studies that have investigated why children and adolescents with chronic pain may experience disruptions in school functioning. A conceptual model of school functioning is presented to summarize factors accumulated to date and to guide future investigations. PMID- 29468930 TI - Navigating Nuances of Language and Meaning: Challenges of Cross-Language Ethnography Involving Shona Speakers Living With Schizophrenia. AB - For people living with schizophrenia, their experience is personal and culturally bound. Focused ethnography enables researchers to understand people's experiences in-context, a prerequisite to providing person-centered care. Data are gathered through observational fieldwork and in-depth interviews with cultural informants. Regardless of the culture, ethnographic research involves resolving issues of language, communication, and meaning. This article discusses the challenges faced by a bilingual, primary mental health nurse researcher when investigating the experiences of people living with schizophrenia in Zimbabwe. Bilingual understanding influenced the research questions, translation of a validated survey instrument and interview transcripts, analysis of the nuances of dialect and local idioms, and confirmation of cultural understanding. When the researcher is a bilingual cultural insider, the insights gained can be more nuanced and culturally enriched. In cross-language research, translation issues are especially challenging when it involves people with a mental illness and requires researcher experience, ethical sensitivity, and cultural awareness. PMID- 29468929 TI - Tumor-derived lactate induces M2 macrophage polarization via the activation of the ERK/STAT3 signaling pathway in breast cancer. AB - Tumor-associated macrophages (TAM) are prominent components of tumor microenvironment (TME) and capable of promoting cancer progression. However, the mechanisms for the formation of M2-like TAMs remain enigmatic. Here, we show that lactate is a pivotal oncometabolite in the TME that drives macrophage M2 polarization to promote breast cancer proliferation, migration, and angiogenesis. In addition, we identified that the activation of ERK/STAT3, major signaling molecules in the lactate signaling pathway, deepens our molecular understanding of how lactate educates TAMs. Moreover, suppression of ERK/STAT3 signaling diminished tumor growth and angiogenesis by abolishing lactate-induced M2 macrophage polarization. Finally, research data of the natural compound withanolide D provide evidence for ERK/STAT3 signaling as a potential therapeutic strategy for the prevention and treatment of breast cancer. These findings suggest that the lactate-ERK/STAT3 signaling pathway is a driver of breast cancer progression by stimulating macrophage M2-like polarization and reveal potential new therapeutic targets for breast cancer treatment. PMID- 29468931 TI - Rituximab is an acceptable alternative to ocrelizumab for treating multiple sclerosis - No. PMID- 29468932 TI - Identification and location tasks rely on different mental processes: a diffusion model account of validity effects in spatial cueing paradigms with emotional stimuli. AB - Spatial cueing paradigms are popular tools to assess human attention to emotional stimuli, but different variants of these paradigms differ in what participants' primary task is. In one variant, participants indicate the location of the target (location task), whereas in the other they indicate the shape of the target (identification task). In the present paper we test the idea that although these two variants produce seemingly comparable cue validity effects on response times, they rest on different underlying processes. Across four studies (total N = 397; two in the supplement) using both variants and manipulating the motivational relevance of cue content, diffusion model analyses revealed that cue validity effects in location tasks are primarily driven by response biases, whereas the same effect rests on delay due to attention to the cue in identification tasks. Based on this, we predict and empirically support that a symmetrical distribution of valid and invalid cues would reduce cue validity effects in location tasks to a greater extent than in identification tasks. Across all variants of the task, we fail to replicate the effect of greater cue validity effects for arousing (vs. neutral) stimuli. We discuss the implications of these findings for best practice in spatial cueing research. PMID- 29468933 TI - Endocrinology and Pediatric Exercise Science-The Year That Was 2017. AB - The Pediatric Exercise Science "Year That Was" section aims to highlight the most important (to the author's opinion) manuscripts that were published in 2017 in the field of endocrinology and pediatric exercise science. This year's selection includes studies showing that 1) in pubertal swimmers, there is a decrease in insulin-like growth factor-1 (IGF-I) and IGF-binding protein-3 (IGFBP-3) during intense training (a catabolic-type hormonal response) with an anabolic "rebound" characterized by a significant increase of these growth factors during training tapering down. Moreover, it was shown that changes of IGF-I and IGFBP-3 paralleled changes in peak and average force but not with endurance properties, showing decreases during intense training and increases during tapering; 2) a meta-analysis showing that growth hormone administration elicits significant changes in body composition and possible limited effect on anaerobic performance but does not increase either muscle strength or aerobic exercise capacity in healthy, young subjects; and 3) short-term exercise intervention can prevent the development of polycystic ovary syndrome in a dose-dependent manner in letrozole induced polycystic ovary syndrome rat model with high-intensity exercise being most effective. The implication of these studies to the pediatric population, their importance, and the new research avenues that were opened by these studies is emphasized. PMID- 29468934 TI - Impact of a Pharmacist-Provided Spirometry Service on Access to Results in a Primary Care Setting. AB - OBJECTIVES: The primary objective of this study was to determine the effect of a pharmacist-provided spirometry service within a federally qualified health center on the percentage of spirometry referrals completed with results reviewed by the ordering provider. Secondary objectives evaluated differences between internal and external referrals, medication recommendations made by the pharmacist, and revenue brought in by the service. METHODS: Chart reviews were completed to determine the referral completion rates between patients who received a spirometry referral before (December 2014-September 2015) and after (January 2016 October 2016) the implementation of the pharmacy-provided spirometry service. Chart reviews were also used to determine the number and completion rate among referrals for internal and external services in the postimplementation time frame. Chart reviews also assessed medication recommendations made by the pharmacist. RESULTS: The results demonstrate an increase in referral completion rate from 38.1% to 47.0% ( P = .08) between the pre- and postimplementation time frames. In the postimplementation time frame, there was a statistically significant difference in the percentage of referrals completed between in-house referrals and external referrals (70.0% and 40.9%, respectively, P = .0004). Comparing clinics with and without the spirometry service, there was a statistically significant difference in the total number of spirometry referrals (1.13% and 0.59%, respectively, P < .0001) and the percent of referrals completed (0.55% and 0.27%, respectively, P = .0002). CONCLUSION: The results suggest that offering spirometry within the primary care setting helps to increase the rate of completed spirometry tests with results available to the primary care provider. Additionally, the results show that there is an increased completion rate in patients who receive an internal spirometry referral, which may be due to reduced barriers in obtaining this testing. Overall, these results demonstrate that providing spirometry in the primary care setting helps to increase spirometry results obtained and could be beneficial in other primary care settings. PMID- 29468935 TI - Changes in hemodynamic classification over time are common in systemic sclerosis associated pulmonary hypertension: insights from the PHAROS cohort. AB - Group classification of pulmonary hypertension (PH) is based on pulmonary artery wedge pressure (PAWP) on right heart catheterization (RHC). How hemodynamics, particularly PAWP, change over time in systemic sclerosis (SSc)-PH patients is unknown. SSc-PH patients enrolled in the prospective observational PHAROS registry who had > 1 RHC (n = 120) were included in this analysis. Patients were considered to have a "PAWP class change" if they had a PAWP <= 15 mmHg on RHC-1 and then a PAWP > 15 on RHC-2 or had a PAWP > 15 on RHC-1 and then PAWP <= 15 on RHC-2. There was a median time of 1.4 years between RHC-1 and RHC-2 and 75% of patients had a PH medication added after their initial RHC. PAWP increased significantly (11 +/- 5 versus 13 +/- 6 mmHg, P = 0.01) between RHC-1 and RHC-2, particularly for patients who were started on PH medications. Overall, 30% of patients who had a repeat RHC experienced a PAWP class change between their initial and follow-up RHC, independent of whether a PH medication was added. Patients initially classified as World Health Organization group 2 PH were most likely to change PAWP class over time. In conclusion, PAWP values commonly change to a significant degree in SSc-PH, which highlights the challenges in using a single time-point PAWP to define clinical classification groups. PMID- 29468937 TI - Evaluation of menthol per se on acute perceptions and behavioral choice of cigarettes differing in nicotine content. AB - Subjective perceptions and self-administration of cigarettes are each influenced by nicotine. Yet, differences specifically due to menthol in perceptions and choice of cigarettes varying in nicotine, and the association between these responses, have not been directly tested. Using a mixed between- and within subjects design, acute responses to each of two menthol or non-menthol Spectrum research cigarettes, moderate (16-17 mg/g) versus very low (0.4 mg/g) in nicotine contents, were compared following brief abstinence in adult smokers preferring menthol ( n=44) or non-menthol ( n=29) brands. To ensure reliable perceptions, they experienced five exposures to each cigarette, then chose between them. All perceptions and choices were greater for moderate vs very low nicotine, as expected, and the magnitude of difference in four of six perceptions was associated with subsequently greater choice of the moderate nicotine cigarette. Importantly, virtually no differences were found between menthol and non-menthol, as nearly all perceptions, cigarette choices, and the association between perceptions and choice were not moderated by menthol or the interaction of nicotine by menthol. Our results indicate perceptions and reinforcement from cigarettes do not differ due to menthol when nicotine content and smoking topography are carefully controlled. Thus, regardless of menthol, smoking perceptions directly predict self-administration behavior.

AB - Latin American social medicine efforts are typically understood as national endeavours, involving health workers, policymakers, academics, social movements, unions, and left-wing political parties, among other domestic actors. But Latin America's social medicine trajectory has also encompassed considerable between country solidarity, building on early twentieth century interchanges among a range of players who shared approaches for improving living and working conditions and instituting protective social policies. Since the 1960s, Cuba's country-to-country solidarity has stood out, comprising medic exchanges, training, and other forms of support for the health and social struggles of oppressed peoples throughout Latin America and around the world, recently via Mision Barrio Adentro in Venezuela. These efforts strive for social justice oriented health cooperation based on horizontal power relations, shared political values, a commitment to social and economic redistribution, bona fide equity, and an understanding of the societal determination of health that includes, but goes well beyond, public health and medical care. With Latin America's left-wing surge now receding, this article traces the provenance, dynamics, impact, challenges, and legacy of health solidarity across Latin American borders and its prospects for continuity. PMID- 29468939 TI - Objectively measuring pain using facial expression: is the technology finally ready? AB - Currently, clinicians observe pain-related behaviors and use patient self-report measures in order to determine pain severity. This paper reviews the evidence when facial expression is used as a measure of pain. We review the literature reporting the relevance of facial expression as a diagnostic measure, which facial movements are indicative of pain, and whether such movements can be reliably used to measure pain. We conclude that although the technology for objective pain measurement is not yet ready for use in clinical settings, the potential benefits to patients in improved pain management, combined with the advances being made in sensor technology and artificial intelligence, provide opportunities for research and innovation. PMID- 29468936 TI - COPD as an endothelial disorder: endothelial injury linking lesions in the lungs and other organs? (2017 Grover Conference Series). AB - Chronic obstructive pulmonary disease (COPD) is characterized by chronic expiratory airflow obstruction that is not fully reversible. COPD patients develop varying degrees of emphysema, small and large airway disease, and various co-morbidities. It has not been clear whether these co-morbidities share common underlying pathogenic processes with the pulmonary lesions. Early research into the pathogenesis of COPD focused on the contributions of injury to the extracellular matrix and pulmonary epithelial cells. More recently, cigarette smoke-induced endothelial dysfunction/injury have been linked to the pulmonary lesions in COPD (especially emphysema) and systemic co-morbidities including atherosclerosis, pulmonary hypertension, and chronic renal injury. Herein, we review the evidence linking endothelial injury to COPD, and the pathways underlying endothelial injury and the "vascular COPD phenotype" including: (1) direct toxic effects of cigarette smoke on endothelial cells; (2) generation of auto-antibodies directed against endothelial cells; (3) vascular inflammation; (4) increased oxidative stress levels in vessels inducing increases in lipid peroxidation and increased activation of the receptor for advanced glycation end products (RAGE); (5) reduced activation of the anti-oxidant pathways in endothelial cells; (6) increased endothelial cell release of mediators with vasoconstrictor, pro-inflammatory, and remodeling activities (endothelin-1) and reduced endothelial cell expression of mediators that promote vasodilation and homeostasis of endothelial cells (nitric oxide synthase and prostacyclin); and (7) increased endoplasmic reticular stress and the unfolded protein response in endothelial cells. We also review the literature on studies of drugs that inhibit RAGE signaling in other diseases (angiotensin-converting enzyme inhibitors and angiotensin receptor blockers), or vasodilators developed for idiopathic pulmonary arterial hypertension that have been tested on cell culture systems, animal models of COPD, and/or smokers and COPD patients. PMID- 29468940 TI - Phone coaching in Dialectical Behavior Therapy: frequency and relationship to client variables. AB - Telephone coaching is a treatment mode in Dialectical Behavior Therapy (DBT) that is designed to help clients generalize skills, prevent suicidal behaviors, and repair therapeutic ruptures. To date, phone coaching has received scant empirical investigation. The aims of this study were to (1) describe patterns in frequency of telephone calls and text messaging in DBT and (2) investigate whether demographic factors, baseline severity, suicidal behaviors, and therapeutic alliance are associated with phone and text frequency. Participants were 51 adults (35 treatment completers) with borderline personality disorder (BPD) in a six-month comprehensive DBT treatment program. Phone coaching frequency was documented by therapist weekly session notes. The average number of contacts per month was 2.55 (SD = 4.49). Four of the 35 treatment completers comprised 56% of the contacts. Having a recent history of suicidal behaviors, degree of severity at baseline, or the strength of the therapeutic alliance was not associated with phone coaching use. However, lower income was significantly associated with a higher frequency of phone coaching use. These preliminary results can help clinicians and administrators make informed decisions on how to better provide phone coaching and clarify the degree of effort involved in providing this service to clients with BPD. PMID- 29468942 TI - Perceptions of Determinants of Condom Use Behaviors Among Male Clients of Female Sex Workers in Indonesia: A Qualitative Inquiry. AB - This study aimed to explore perceived determinants of condom use behaviors among male clients of female commercial sex workers (FCSWs) in Belu and Malaka districts, Indonesia. One-on-one in-depth interviews guided by the Health Belief Model (HBM) were used to collect the data from participants ( n = 42). The Framework analysis for qualitative data was employed to analyze the data. Results demonstrated several factors associated with lack of and inconsistent condom use among the participants. They included self-perceived risk of contracting HIV infection, knowledge of the severity of HIV illness and its impacts, and condom use: its benefits and its influencing factors. Additionally, factors including reduced sexual pleasure and the lack of knowledge of how and where to access condoms were important perceived barriers to condom use among participants. Having seen images of HIV-/AIDS-positive people, knowing friends and relatives suffering from HIV, and knowing FCSWs as a high-risk group for HIV infection were the cues to using condoms among several participants. Likewise, self-efficacy was also associated with condom use behaviors among the participants. The findings indicate the needs for HIV/AIDS interventions that include dissemination of HIV/AIDS knowledge, condom promotion, and improvement in the availability of condoms for both FCSWs and their clients. PMID- 29468943 TI - The informative error: A framework for the construction of individualized phenotypes. AB - For the goal of individualized medicine, it is critical to have clinical phenotypes at hand which represent the individual pathophysiology. However, for most of the utilized phenotypes, two individuals with the same phenotype assignment may differ strongly in their underlying biological traits. In this paper, we propose a definition for individualization and a corresponding statistical operationalization, delivering thereby a statistical framework in which the usefulness of a variable in the meaningful differentiation of individuals with the same phenotype can be assessed. Based on this framework, we develop a statistical workflow to derive individualized phenotypes, demonstrating that under specific statistical constraints the prediction error of prediction scores contains information about hidden biological traits not represented in the modeled phenotype of interest, allowing thereby internal differentiation of individuals with the same assigned phenotypic manifestation. We applied our procedure to data of the population-based Study of Health in Pomerania to construct a refined definition of obesity, demonstrating the utility of the definition in prospective survival analyses. Summarizing, we propose a framework for the individualization of phenotypes aiding personalized medicine by shifting the focus in the assessment of prediction models from the model fit to the informational content of the prediction error. PMID- 29468944 TI - Estimating cost-effectiveness from claims and registry data with measured and unmeasured confounders. AB - The analysis of observational data to determine the cost-effectiveness of medical treatments is complicated by the need to account for skewness, censoring, and the effects of measured and unmeasured confounders. We quantify cost-effectiveness as the Net Monetary Benefit (NMB), a linear combination of the treatment effects on cost and effectiveness that denominates utility in monetary terms. We propose a parametric estimation approach that describes cost with a Gamma generalized linear model and survival time (the canonical effectiveness variable) with a Weibull accelerated failure time model. To account for correlation between cost and survival, we propose a bootstrap procedure to compute confidence intervals for NMB. To examine sensitivity to unmeasured confounders, we derive simple approximate relationships between naive parameters, assuming only measured confounders, and the values those parameters would take if there was further adjustment for a single unmeasured confounder with a specified distribution. A simulation study shows that the method returns accurate estimates for treatment effects on cost, survival, and NMB under the assumed model. We apply our method to compare two treatments for Stage II/III bladder cancer, concluding that the NMB is sensitive to hypothesized unmeasured confounders that represent smoking status and personal income. PMID- 29468941 TI - The serotonin hypothesis in pulmonary hypertension revisited: targets for novel therapies (2017 Grover Conference Series). AB - Increased synthesis of serotonin and/or activity of serotonin in pulmonary arteries has been implicated in the pathobiology of pulmonary arterial hypertension (PAH). The incidence of PAH associated with diet pills such as aminorex, fenfluramine, and chlorphentermine initially led to the "serotonin hypothesis of pulmonary hypertension." Over the last couple of decades there has been an accumulation of convincing evidence that targeting serotonin synthesis or signaling is a novel and promising approach to the development of novel therapies for PAH. Pulmonary endothelial serotonin synthesis via tryptophan hydroxlase 1 (TPH1) is increased in patients with PAH and serotonin can act in a paracrine fashion on underlying pulmonary arterial smooth muscle cells (PASMCs), In humans, serotonin can enter PASMCs via the serotonin transporter (SERT) or activate the 5 HT1B receptor; 5-HT1B activation and SERT activity cooperate to induce PASMC contraction and proliferation via activation of downstream proliferative and contractile signaling pathways. Here we will review the current status of the serotonin hypothesis and discuss potential and novel therapeutic targets. PMID- 29468945 TI - A novel identification approach for discovery of 5-HydroxyTriptamine 2A antagonists: combination of 2D/3D similarity screening, molecular docking and molecular dynamics. AB - 5-HydroxyTriptamine 2A antagonists are potential targets for treatment of various cerebrovascular and cardiovascular disorders. In this study, we have developed and performed a unique screening pipeline for filtering ZINC database compounds on the basis of similarities to known antagonists to determine novel small molecule antagonists of 5-HydroxyTriptamine 2A. The screening pipeline is based on 2D similarity, 3D dissimilarity and a combination of 2D/3D similarity. The shortlisted compounds were docked to a 5-HydroxyTriptamine 2A homology-based model, and complexes with low binding energies (287 complexes) were selected for molecular dynamics (MD) simulations in a lipid bilayer. The MD simulations of the shortlisted compounds in complex with 5-HydroxyTriptamine 2A confirmed the stability of the complexes and revealed novel interaction insights. The receptor residues S239, N343, S242, S159, Y370 and D155 predominantly participate in hydrogen bonding. pi-pi stacking is observed in F339, F340, F234, W151 and W336, whereas hydrophobic interactions are observed amongst V156, F339, F234, V362, V366, F340, V235, I152 and W151. The known and potential antagonists shortlisted by us have similar overlapping molecular interaction patterns. The 287 potential 5-HydroxyTriptamine 2A antagonists may be experimentally verified.

PMID- 29468946 TI - Design, implementation, and interpretation of amplification studies for prion detection. AB - Amplification assays for transmissible spongiform encephalopathies have been in development for close to 15 years, with critical implications for the postmortem and antemortem diagnosis of human and animal prion diseases. Little has been published regarding the structured development, implementation and interpretation of experiments making use of protein misfolding cyclic amplification (PMCA) and real time quaking-induced conversion (RT-QuIC), and our goal with this Perspectives manuscript is to offer a framework which might allow for more efficient expansion of pilot studies into diagnostic trials in both human and animal subjects. This framework is made up of approaches common to diagnostic medicine, including a thorough understanding of analytical and diagnostic sensitivity and specificity, an a priori development of amplification strategy, and an effective experimental design. It is our hope that a structured framework for prion amplification assays will benefit not only experiments seeking to sensitively detect naturally-occurring cases of prion diseases and describe the pathogenesis of TSEs, but ultimately assist with future endeavors seeking to use these methods more broadly for other protein misfolding disorders, including Alzheimer's and Parkinson's disease. PMID- 29468948 TI - Preventing Musculoskeletal Disorders in Factory Workers: Evaluating a New Eight Minute Stretching Program. AB - A preshift stretching program was implemented to evaluate its effectiveness in preventing work-related musculoskeletal disorders (WMSD). Workers in a Midwestern factory were assessed for WMSDs before and after the new 8-min stretching program was implemented. Aggregate WMSD data were evaluated and sick days used from the start of the new program were compared with the same 60-day period the previous year. Potential cost savings were also assessed. The researchers found a significant decline in injury rates and time-off requests. Cost savings were noted for both the employer and employees. Additional studies with more workers, as well as longitudinal designs are recommended to verify the findings in this program evaluation study. PMID- 29468949 TI - Methodologies for Investigating Performance Changes With Supplement Use. AB - Many expert sporting bodies now support a pragmatic acceptance of the use of performance supplements which have passed a risk:benefit analysis of being safe, effective, and permitted for use, while also being appropriate to the athlete's age and maturation in their sport. However, gaining evidence of the performance benefits of these supplements is a process challenged by the scarcity of research in relation to the number of available products, and the limitations of the poor quality of some studies. While meta-analyses and systematic reviews can help to provide information about the general use of performance supplements, the controlled scientific trial provides the basis on which these reviews are undertaken, as well as an opportunity to address more specific questions about supplement applications. Guidelines for the design of studies include the choice of well-trained athletes who are familiarized with performance tasks that have been chosen on their basis of their known reliability and validity. Supplement protocols should be chosen to maximize the likely benefits, and researchers should also make efforts to control confounding variables, while keeping conditions similar to real-life practices. Performance changes should be interpreted in light of what is meaningful to the outcomes of sporting competition. Issues that have been poorly addressed to date include the use of several supplements in combination and the use of the same supplement over successive events, both within a single, and across multiple competition days. Strategies to isolate and explain the variability of benefits to individuals are also a topic for future investigation.

PMID- 29468951 TI - Cost-effectiveness thresholds: methods for setting and examples from around the world. AB - INTRODUCTION: Cost-effectiveness thresholds (CETs) are used to judge if an intervention represents sufficient value for money to merit adoption in healthcare systems. The study was motivated by the Brazilian context of HTA, where meetings are being conducted to decide on the definition of a threshold. Areas covered: An electronic search was conducted on Medline (via PubMed), Lilacs (via BVS) and ScienceDirect followed by a complementary search of references of included studies, Google Scholar and conference abstracts. Cost-effectiveness thresholds are usually calculated through three different approaches: the willingness-to-pay, representative of welfare economics; the precedent method, based on the value of an already funded technology; and the opportunity cost method, which links the threshold to the volume of health displaced. An explicit threshold has never been formally adopted in most places. Some countries have defined thresholds, with some flexibility to consider other factors. An implicit threshold could be determined by research of funded cases. Expert commentary: CETs have had an important role as a 'bridging concept' between the world of academic research and the 'real world' of healthcare prioritization. The definition of a cost-effectiveness threshold is paramount for the construction of a transparent and efficient Health Technology Assessment system. PMID- 29468953 TI - Socioeconomic differences in the use of alcohol and drunkenness in adolescents: Trends in the Health Behaviour in School-aged Children study in Finland 1990 2014. AB - AIMS: The aims of this study were to explore time-based trends of socioeconomic differences in alcohol use and drunkenness in Finnish adolescents from 1990 to 2014 and to investigate the significance of two indicators in detecting socioeconomic differences in alcohol use and drunkenness. METHODS: Data were retrieved from seven surveys conducted as part of the Health Behaviour in School aged Children (HBSC) study in Finland from 1990 to 2014. The alcohol use and drunkenness of 15-year-old students, as well as socioeconomic status, including educational aspiration and perceived family wealth, were assessed via a self report questionnaire. Logistic regression models were used to investigate the relationships between alcohol use, drunkenness and indicators of socioeconomic status. RESULTS: The study showed that the alcohol use and drunkenness of Finnish 15-year-old adolescents have decreased since the late 1990s. However, the level of decrease is not consistent among different socioeconomic groups and socioeconomic differences in drinking behaviour between two educational aspiration groups have persisted over two decades. Girls from the groups with low perceived family wealth were more likely to be frequently drunk in the time period 2006-2014. CONCLUSIONS: This study suggests that students with low educational aspiration should be the target population for interventions aiming at reducing the alcohol use and drunkenness of Finnish adolescents. In future interventions aimed at reducing heavier drinking, adolescents (especially girls) from less wealthy families should be the first priority. Further studies on trends in socioeconomic differences in alcohol use and drunkenness in adolescence should be conducted using different indicators of socioeconomic status and other social context factors should also be taken into account.

AB - Construction of antibacterial surfaces or films is of great interest in various fields including biomedicine, food, agriculture and so on. So far, a number of antibacterial agents have been used to construct antibacterial surfaces. Layer-by Layer (LbL) assembly is a simple and versatile deposition process for fabricating multilayer thin films with great advantages to control the architecture and composition of the films. In this review, we give a brief introduction of LbL, and different materials used to fabricate antibacterial surfaces with LbL assembly approach are described as well as their drawbacks. Much attention is also paid to the recent development of multifunctional and intelligent antibacterial surfaces. Moreover, the advantages and limitations of these different types of antibacterial materials are summarized and subsequently directions for future development are proposed. PMID- 29468956 TI - Antibacterial Metal Oxide Nanoparticles: Challenges in Interpreting the Literature. AB - Metal oxide nanoparticles (MO-NPs) are known to effectively inhibit the growth of a wide range of Gram-positive and Gram-negative bacteria. They have emerged as promising candidates to challenge the rising global issue of antimicrobial resistance. However, a comprehensive understanding of their mechanism of action and identifying the most promising NP materials for future clinical translation remain a major challenge due to variations in NP preparation and testing methods. With various types of MO-NPs being rapidly developed, a robust, standardized, in vitro assessment protocol for evaluating the antibacterial potency and efficiency of these NPs is needed. Calculating the number of NPs that actively interact with each bacterial cell is critical for assessing the dose response for toxicity. Here we discuss methods to evaluate MO-NPs antibacterial efficiency with focus on issues related to NPs in these assays. We also highlight sources of experimental variability including NP preparation, initial bacterial concentration, bacterial strains tested, culture microenvironment, and reported dose. PMID- 29468957 TI - Antibacterial Coatings Based on Chitosan for Pharmaceutical and Biomedical Applications. AB - The risk of bacterial colonization of abiotic surfaces of biomedical devices poses important challenges for the pharmaceutical and biomaterials science fields. In this scenario, antibacterial coatings have been developed, using a number of different molecules and materials. Among them, chitosan is a non cytotoxic, biocompatible biopolymer with an inherent antimicrobial activity that has been already used in a wide variety of healthcare and industrial applications. Herein, chitosan-based antibacterial coatings are critically surveyed, with a special emphasis on their production methods, pharmaceutical and biomedical applications, along with their pros and cons, and finally highlighting the key challenges to be faced and future perspectives in this field. PMID- 29468958 TI - Impact of Pre-procedural Cerebrovascular Events on Clinical Outcomes After Transcatheter Aortic Valve Implantation in Patients with Severe Aortic Stenosis. AB - BACKGROUND: Transcatheter aortic valve implantation (TAVI) is an increasingly common treatment of symptomatic severe aortic valve stenosis (AS). Thus, it is reasonable to carefully investigate the impact of individual clinical factors on outcomes after TAVI. OBJECTIVES: We aimed to investigate the impact of the previous cerebro-vascular events (CVEs) on outcomes of patients with severe AS undergoing TAVI. METHODS: A total of 148 consecutive patients scheduled for TAVI were included and stratified as with and without a history of CVEs (stroke or transient ischemic attack). Frailty features were also assessed. The primary endpoint was a 12-month all-cause mortality. RESULTS: Seventeen (11.5%) patients had a history of CVEs (the CVE group). At 30 days and 12 months, all-cause mortality was higher in the CVE group [30-day: 5 (29.4%) vs. 7 (5.3%); p=0.005; 12-month: 9 (52.9%) vs. 13 (9.9%); p=0.001]. Similarly, at the longest available follow-up, mortality was higher in the CVE group [10 (58.8%) vs. 23 (17.6%); p=0.001]. Similar rates of other complications after TAVI were noted, apart from inhospital acute kidney injury (AKI) grade 3 [3 (17.6%) vs. 5 (3.8%); p=0.049] and blood transfusions [9 (52.9%) vs. 35 (26.7%); p=0.026]. Results of 5MWT and Katz index assessment indicated a greater level of frailty in the CVE group. There were no differences in subsequent events including CVEs, bleeding, myocardial infarction, and new-onset of atrial fibrillation (AF) at 12 months between the groups. CONCLUSION: We showed that a history of CVEs in patients with severe AS undergoing TAVI is associated with a higher long-term mortality. PMID- 29468959 TI - In-silico Studies of Isolated Phytoalkaloid Against Lipoxygenase: Study Based on Possible Correlation. AB - AIM AND OBJECTIVE: Lipoxygenase (LOX) enzymes play an important role in the pathophysiology of several inflammatory and allergic diseases including bronchial asthma, allergic rhinitis, atopic dermatitis, allergic conjunctivitis, rheumatoid arthritis and chronic obstructive pulmonary disease. Inhibitors of the LOX are believed to be an ideal approach in the treatment of diseases caused by its over expression. In this regard, several synthetic and natural agents are under investigation worldwide. Alkaloids are the most thoroughly investigated class of natural compounds with outstanding past in clinically useful drugs. In this article, we have discussed various alkaloids of plant origin that have already shown lipoxygenase inhibition in-vitro with possible correlation in in silico studies. MATERIALS AND METHODS: Molecular docking studies were performed using MOE (Molecular Operating Environment) software. Among the ten reported LOX alkaloids inhibitors, derived from plant, compounds 4, 2, 3 and 1 showed excellent docking scores and receptor sensitivity. RESULT AND CONCLUSION: These compounds already exhibited in vitro lipoxygenase inhibition and the MOE results strongly correlated with the experimental results. On the basis of these in vitro assays and computer aided results, we suggest that these compounds need further detail in vivo studies and clinical trial for the discovery of new more effective and safe lipoxygenase inhibitors. In conclusion, these results might be useful in the design of new and potential lipoxygenase (LOX) inhibitors. PMID- 29468960 TI - The Discovery of Antibacterial Natural Compound Based on Peptide Deformylase. AB - BACKGROUND: In recent years, Staphylococcus aureus have developed resistance to medicines used for the treatment of human infections. Therefore, the search for antibacterial agents of high potency against Staphylococcus aureus is of great concern. Peptide deformylase (PDF), a metalloprotease catalyzing the removal of a formyl group from newly synthesized proteins, has been considered to be an important antibacterial drug target. OBJECTIVE: To discover novel antibacterial drugs based on Staphylococcus aureus peptide deformylase. METHOD: PDF-based virtual screening of compounds from Traditional Chinese Medicine Database@Taiwan was performed by Sybyl X2.1 Surflex dock software. Compounds which possess high docking score were used for the following antibacterial experiments to evaluate their antibacterial activities. Kanamycin was also used in the antibacterial experiment as a control substance in the assay. Furthermore, molecular docking studies was applied to elucidate binding interaction between some compounds and PDF. In silico pharmacokinetic and toxicity prediction was explored to explain the reasons why these compounds might stand good chance of providing some pharmaceutical benefits. RESULTS: Gentiopicroside, protosappanin B, dihydromyricetin and cryptochlorogenic acid with high docking score were used for our subsequent antibacterial assays. The Minimum Inhibitory Concentration (MIC) of kanamycin and gentiopicroside were 0.008 mg.mL-1 and 0.431 mg.mL-1, respectively, other three compounds, protosappanin B, dihydromyricetin and cryptochlorogenic acid have close MIC value of 0.50 mg.mL-1. CONCLUSION: Dihydromyricetin, with the MIC value of 0.50 mg.mL-1 and relatively high drug score of 0.82, may serve as a novel antibacterial lead compound. PMID- 29468961 TI - A Green Synthesis of Xanthenone Derivatives in Aqueous Media Using TiO2-CNTs Nanocomposite as an Eco-Friendly and Re-Usable Catalyst. AB - AIM AND OBJECTIVE: The xanthene (dibenzopyran) framework constitutes the core structure of many biologically active compounds, that they have been of interest because of their pharmacological activities like antiviral, antibacterial, anti inflammatory, and CCR1 antagonist. As heterogeneous catalysts offer several advantages over homogeneous catalysts, the performance of reactions on the surface of nanosized heterogeneous salts has received a great deal of interest in recent years. In the area of nanosized heterogeneous catalysts there is a noticeable range of reactions that are catalyzed efficiently by TiO2 NPs. Moreover, carbon nanotubes (CNTs) as a support can be used to obtain nanoparticles with modified morphology, structural, chemical, electrical, and optical properties. The catalytic activity of titanium dioxide supported on carbon nanotubes has been greatly improved. MATERIALS AND METHODS: The present methodology focus on the synthesis of 7,7-dimethyl-10-aryl- 6,7,8,10-tetrahydro 9H-[1,3]dioxolo[4,5-b]xanthen-9-ones, through a condensation reaction of dimedone, aromatic aldehydes and 3,4-methylenedioxyphenol, using a catalytic amount of TiO2- CNTs nanocomposite (15 mol%) at 80 C in aqueous media, within 60 90 min. The TiO2-CNTs nanocomposite was also prepared by a known simple sonochemical method. RESULTS: A series of 7,7-dimethyl-10-aryl-6,7,8,10 tetrahydro-9H-[1,3]dioxolo[4,5-b]xanthen-9-ones were successfully synthesized in high yields (92-98%). All synthesized compounds were well characterized by their satisfactory elemental analyses, IR, 1H and 13C NMR spectroscopy. The synthesized catalyst was fully characterized by SEM, TEM, XRD, and EDX techniques. CONCLUSION: In summary, this investigation constitutes a novel and efficient route for the synthesis of 7,7-dimethyl-10-aryl-6,7,8,10-tetrahydro-9H [1,3]dioxolo[4,5-b]xanthen-9-ones in high yields, by a three-component reaction of dimedone, aromatic aldehydes and 3,4-methylenedioxyphenol in water and in the presence of the TiO2-CNTs nanocomposite as a green, effective and recyclable catalyst. This novel method has the advantages of high yields, mild reaction conditions, short reaction time, easy work-up, inexpensive reagents and environmentally friendly procedure. PMID- 29468962 TI - Plant-Derived Polyphenols in Human Health: Biological Activity, Metabolites and Putative Molecular Targets. AB - BACKGROUND: Hibiscus sabdariffa, Lippia citriodora, Rosmarinus officinalis and Olea europaea, are rich in bioactive compounds that represent most of the phenolic compounds' families and have exhibited potential benefits in human health. These plants have been used in folk medicine for their potential therapeutic properties in human chronic diseases. Recent evidence leads to postulate that polyphenols may account for such effects. Nevertheless, the compounds or metabolites that are responsible for reaching the molecular targets are unknown. OBJECTIVE: data based on studies directly using complex extracts on cellular models, without considering metabolic aspects, have limited applicability. In contrast, studies exploring the absorption process, metabolites in the blood circulation and tissues have become essential to identify the intracellular final effectors that are responsible for extracts bioactivity. Once the cellular metabolites are identified using high-resolution mass spectrometry, docking techniques suppose a unique tool for virtually screening a large number of compounds on selected targets in order to elucidate their potential mechanisms. RESULTS: we provide an updated overview of the in vitro and in vivo studies on the toxicity, absorption, permeability, pharmacokinetics and cellular metabolism of bioactive compounds derived from the abovementioned plants to identify the potential compounds that are responsible for the observed health effects. CONCLUSION: we propose the use of targeted metabolomics followed by in silico studies to virtually screen identified metabolites on selected protein targets, in combination with the use of the candidate metabolites in cellular models, as the methods of choice for elucidating the molecular mechanisms of these compounds. PMID- 29468963 TI - NF-kappaB-IKKbeta Pathway as a Target for Drug Development: Realities, Challenges and Perspectives. AB - BACKGROUND: Nuclear factor kappaB (NF-kappaB) comprises a family of proteins that act as transcription factors promoting the expression of many genes. Activation of NF-kappaB biochemical cascades is associated with the regulation of innate and adaptive immune responses and inflammation, among other physiological responses. However, genetic abnormalities and continuous stimulation of the NF- kappaB IKKbeta pathway are directly related to many types of inflammatory and autoimmune diseases, as well as to the genesis and survival of tumor cells. OBJECTIVES: Inhibition of the NF-kappaB-IKKbeta cascade can be considered an attractive therapeutic method for the genesis of new prototypes to combat these chronic multifactorial diseases. RESULTS: This review describes some prototypes and drugs that act to inhibit the NF-kappaB-IKKbeta pathway, highlighting the realities, challenges and perspectives for therapeutic use. CONCLUSION: Although only proteasome inhibitors, such as bortezomib and carfilzomib, are a reality as therapeutically useful drugs among the known modulators of possible targets in the NF-kappaB-IKKbeta pathway, some other prototypes described as IKKbeta inhibitors have entered clinical stages as drug candidates for the control of inflammatory diseases. It is important to note that some classical drugs available on the pharmaceutical market, such as acetylsalicylic acid, were also described more recently as NF-kappaB pathway modulators as IKKbeta inhibitors. PMID- 29468964 TI - Recent Advances in Antibacterial, Antiprotozoal and Antifungal Trends of Eurycoma longifolia: A Review of Therapeutic Implications and Future Prospects. AB - BACKGROUND: Eurycoma longifolia (E. longifolia) has gained widespread recognition due to its versatile pharmacological activities including aphrodisiac, anticancer, antimicrobial, antioxidant, anti-inflammatory, anxiolytic, anti diabetic, ergogenic, insecticidal, anti-rheumatism, bone protection, and anti ulcer effects. OBJECTIVE: This review was aimed to critically overview the literature and summarizes the antibacterial, antiprotozoal, and antifungal trends of E. longifolia and its medicinally active components. RESULTS: Besides its well documented safety, efficacy, and tolerability, a plethora of in vitro, in vivo, and human clinical studies has evidenced the antimicrobial efficacy of E. longifolia and its bioactive constituents. Phytochemical screening of various types of extracts (methanolic, ethyl acetate, and nbutanolic) from different parts (roots, stem, and leaves) of E. longifolia displayed a dose-dependent antibacterial, antiprotozoal, and antifungal responses. Comparative analysis revealed that the root extract of E. longifolia exhibited the highest antimicrobial efficacy compared to other parts of the plant. Bioactivity-guided fractionation identified that among all of the medicinal compounds isolated/ extracted from different parts of E. longifolia, eurycomanone displayed the strongest antibacterial, antiprotozoal and antifungal activities. CONCLUSION: Based on the critical analysis of the literature, we identified that E. longifolia exhibits promising antibacterial, antiprotozoal, and antifungal efficacies against various pathogenic microbes and thus can be considered as a potential complementary and alternative antimicrobial therapy. PMID- 29468965 TI - Versatility of Cancer Associated Fibroblasts: Commendable Targets for Anti-tumor Therapy. AB - BACKGROUND AND OBJECTIVE: Tumor growth, development, progression, metastasis, invasion and resistivity against drugs solely depend on the recruitment of surrounding cells, extracellular matrix and Tumor Microenvironment (TME). TME is directly as well as indirectly associated with Cancer- Associated Fibroblasts (CAF). The interactions of CAF with tumor surrounding cells, their origination, activation, transformation and ability to recruit other non-tumor cells for the clemency of tumor, are very complex and under active research since long. This study provides an in-depth review of CAF and highlights its potential targets for the regulation of TME as well as discusses current drugs in clinical trials, targeting through CAF. CONCLUSION: The potential role of CAF in anti-tumor therapy is based on its coherent response against drugs, targeting different tumor sections through these genetically more stable and anti-immunosupportive CAF cells. CAF can be targeted through immunity system; Growth Factors (GF) including Transforming growth factor (TGF), vascular endothelial GF, fibroblast GF, platelet derived GF; and TME elements including hypoxia, carbonic anhydrase, extracellular matrix (ECM). Collectively these features of CAF make it most vulnerable against single as well as combinational, anti-tumor therapy for synergistic or additive effects. Potential activities of CAF, their origination mechanisms and identification of meticulous bio-markers are needed to be investigated further. The rousing facts about them mutually culminate the anticipation of progress towards novel therapeutic establishment against cancer through CAFs that are under progressive research at all levels including, pre clinical and clinical trials as well as possess much potential to be explored further.

PMID- 29468967 TI - Recent Advances in Development of Polyphenols as Anticancer Agents. AB - Still now, for many forms of the disseminated cancers there is no curative therapy available. The discovery of novel active chemotherapeutic agents is largely essential to overcome this problem. Natural compounds polyphenols are mainly characterized by a huge structural variance; they can render them intrinsic dietary components due to their common occurrence in plants. Now-a days, polyphenols (secondary metabolites) are characterized by a vast spectrum of physiological significance. From the past twenty years in the world of scientific research, polyphenols play an important role in a wide range of physiological processess. This review focuses on the development of polyphenols as antitumor agent in recent research studies. PMID- 29468968 TI - Arginine Functionalized Bacterial Cellulose Nanofibers Containing Gel as an Effective Wound Dressing: In vitro and In vivo Evaluation. AB - BACKGROUND: Nanofibers such as bacterial cellulose nanofibers (BC-NFs) have gained increasing attention for use in wound dressings. Topical application of arginine can stimulate wound healing significantly. OBJECTIVE: In order to promote the wound healing process, arginine functionalized BC-NFs containing gel (Arg-BC-NFs gel) was prepared by the electrostatic attachment of arginine on the surface of BCNFs. METHOD: The effect of pH was evaluated on the amount of the attached arginine on the BC-NFs surface. The attachment of arginine on BC-NFs surface was investigated by FTIR spectroscopy. The morphology of Arg-BC-NFs was evaluated using FESEM. The viscosity and spreadability of Arg-BC-NFs and the release of arginine from Arg-BC-NFs were evaluated. The effectiveness of Arg-BC NFs gel was assessed in a full thickness wound model in rats. Re-epithelization, collagen deposition and neovascularization were investigated in the wound tissues using histological and immunohistochemical analysis. RESULTS: FTIR spectra and the zeta potential of BC-NFs confirmed the surface modification of BC-NFs by arginine. FESEM images showed the nanofibrous structure of Arg-BC-NFs. The release of arginine from Arg-BC-NFs gel was in a sustained release manner for 24 h. The appropriate viscosity and spreadability of Arg-BC-NFs gel confirmed its easy topical application. In vivo studies revealed that Arg-BCNFs gel promoted wound closure at a faster rate than BC-NFs gel and arginine solution. Moreover, faster and more organized re-epithelialization, angiogenesis and collagen deposition were achieved in Arg-BC-NFs gel treated group in comparison to other groups. CONCLUSION: Arg-BC-NFs gel can be introduced as an effective wound dressing for acute wounds. PMID- 29468969 TI - RAFTing Towards the Shore of Nanotherapeutic. PMID- 29468970 TI - Comparative Genetic Variability in HIV-1 Subtype C vpu Gene in Early Age Groups of Infants. AB - OBJECTIVE: Identifying the genetic variability in vertically transmitted viruses in early infancy is important to understand the disease progression. Being important in HIV-1 disease pathogenesis, vpu gene, isolated from young infants was investigated to understand the viral characteristics. METHOD: Blood samples were obtained from 80 HIV-1 positive infants, categorized in two age groups; acute (<6 months) and early (>6-18 months). A total of 77 PCR positive samples, amplified for vpu gene, were sequenced and analyzed. RESULTS: 73 isolates belonged to subtype C. Analysis of heterogeneity of amino acid sequences in infant groups showed that in the sequences of acute age group both insertions and deletions were present while in the early age group only deletions were present. In the acute age group, a deletion of 3 residues (RAE) in the first alfa helix in one sequence and insertions of 1-2 residues (DM, GH, G and H) in the second alfa helix in 4 sequences were observed. In the early age group, deletion of 2 residues (VN) in the cytoplasmic tail region in 2 sequences was observed. Length of the amino terminal was observed to be gradually increasing with the increasing age of the infants. Protein Variation Effect Analyzer software showed that deleterious mutations were more in the acute than the early age group. Entropy analysis revealed that heterogeneity of the residues was comparatively higher in the sequences of acute than the early age group. CONCLUSION: Mutations observed in the helixes may affect the conformation and lose the ability to degrade CD4 receptors. Heterogeneity was decreasing with the increasing ages of the infants, indicating positive selection for robust virion survival. PMID- 29468971 TI - IL-10 Promoter -592 Polymorphism may Influence Susceptibility to HIV Infection in South Indian Population. AB - BACKGROUND: Genetic factors play an important role in the development of disease susceptibility or protection. Cytokine gene polymorphisms are reported to be associated with altered levels of cytokine production that can impact disease progression in HIV and TB. OBJECTIVE: In this study, we studied IL-10 -592(C/A) and TGF-beta -509 (C/T) promoter polymorphisms to understand their role in susceptibility or resistance to HIV and TB in a South Indian population. METHOD: Genomic DNA was isolated from healthy controls, pulmonary tuberculosis patients (n=122) and HIV positive individuals (n=100) and used for genotyping by polymerase chain reaction followed by restriction fragment length polymorphism (PCR-RFLP) method. RESULTS: Results revealed that under dominant model (CC vs CA+AA), IL-10 -592 'A' allele either 'CA' or 'AA' combinations significantly associated with susceptibility to HIV compared to healthy controls (OR: 1.88(1.05 3.35); p=0.030). However, we found no significant association with TB. TGF-beta 509 polymorphism did not associate with either HIV or TB under overdominant model. Neither of the promoter polymorphisms associated with sex in either HIV or TB. However, a trend towards higher risk to HIV was found in females compared with males in IL-10 -592 'AA' genotype. CONCLUSION: This study suggests the association of IL-10 -592 "AA" genotype with susceptibility to HIV under dominant model in the Southern Indian population. Future studies are needed with a larger sample size in order to confirm the observations made in this study. PMID- 29468972 TI - Investigating HIV-Human Interaction Networks to Unravel Pathogenic Mechanism for Drug Discovery: A Systems Biology Approach. AB - BACKGROUND: Two big issues in the study of pathogens are determining how pathogens infect hosts and how the host defends itself against infection. Therefore, investigating host-pathogen interactions is important for understanding pathogenicity and host defensive mechanisms and treating infections. METHODS: In this study, we used omics data, including time-course data from high-throughput sequencing, real-time polymerase chain reaction, and human microRNA (miRNA) and protein-protein interaction to construct an interspecies protein-protein and miRNA interaction (PPMI) network of human CD4+ T cells during HIV-1 infection through system modeling and identification. RESULTS: By applying a functional annotation tool to the identified PPMI network at each stage of HIV infection, we found that repressions of three miRNAs, miR-140-5p, miR-320a, and miR-941, are involved in the development of autoimmune disorders, tumor proliferation, and the pathogenesis of T cells at the reverse transcription stage. Repressions of miR-331-3p and miR-320a are involved in HIV-1 replication, replicative spread, anti-apoptosis, cell proliferation, and dysregulation of cell cycle control at the integration/replication stage. Repression of miR-341-5p is involved in carcinogenesis at the late stage of HIV-1 infection. CONCLUSION: By investigating the common core proteins and changes in specific proteins in the PPMI network between the stages of HIV-1 infection, we obtained pathogenic insights into the functional core modules and identified potential drug combinations for treating patients with HIV-1 infection, including thalidomide, oxaprozin, and metformin, at the reverse transcription stage; quercetin, nifedipine, and fenbendazole, at the integration/replication stage; and staurosporine, quercetin, prednisolone, and flufenamic acid, at the late stage. PMID- 29468973 TI - Molecular Docking In Formulation And Development. AB - In pharmaceutical research drug discovery and development process is time consuming and expensive. In many cases, it produces incompetent results due to the failure of in vitro and in vivo conventional approaches. Before any new drug is placed in the market it must undergo rigorous testing to get FDA approval. Due to the several limitations imposed by the drug discovery process, in recent times in silico approaches are widely applied in this field. In this review we have compiled docking studies which has found it's applications to predict drug excipient interactions which in turn assist to increase protein stability; to determine enzyme peptide interactions which maybe further used in drug development studies; to determine the most stable drug inclusion complex; to analyze structure at molecular level that ascertain an increase in solubility, dissolution and in turn the bioavailability of the drug; to design a dosage form that amplify the drug discovery and development process. The purpose of this review is to highlight the current molecular docking strategies used in drug discovery and to explore various advances in the field. PMID- 29468974 TI - Potentials of PKC in cancer progression and anticancer drug development. AB - PKC are a family of serine-threonine kinases which play crucial roles in the regulation of important signal transduction pathways in mammalian cell-biology. These enzymes are themselves regulated by various molecules that can serve as ligands to the regulatory domains and translocate PKC to membrane for activity. The role of PKC in the modulation of both proliferative and apoptotic signalling in cancer become a subject of intense interest after it was discovered that PKC regulates a myriad of enzymes and transcription factors involved in carcinogenic signalling. Therefore, PKC has served as an attractive target for the development of newer generation of anti-cancer drugs. The following review discusses the potential of PKC to be regarded as a target for anti-cancer therapy. We also review all the molecules that have been discovered so far to be regulators/activators/inhibitors of PKC and also how far these molecules can be considered as potential candidates for anti-cancer drug development based on PKC. PMID- 29468975 TI - The Protective Effects of Green Tea Catechins in the Management of Neurodegenerative Diseases: A Review. AB - The therapeutic strategies to manage neurodegenerative diseases remain limited and it is necessary to discover new agents for their prevention and control. Oxidative stress and inflammation play a main role in the pathogenesis of neurodegenerative diseases. Catechins, the major flavonoids in green tea, are powerful antioxidants and radical scavengers that possess the potential roles in the management of neurodegenerative diseases. Catechins modulate the cellular and molecular mechanisms through the inflammation-related NF-kB and the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathways. Present review shows catechins could be effective against neurodegenerative diseases due to their antioxidation and anti-inflammation effects and the involved biochemical pathways including Nrf2 and NF-kB signaling pathways. PMID- 29468976 TI - Toxicity of Biologically Active Peptides and Future Safety Aspects: An Update. AB - INTRODUCTION: Peptides are fragments of proteins with significant biological activities. These peptides are encoded in the protein sequence. Initially, such peptides are inactive in their parental form, unless proteolytic enzymes are released. These peptides exhibit various functions and play a therapeutic role in the body. OBJECTIVE: Besides the therapeutic and physiological activities of peptides, the main purpose of this study was to highlight the safety aspects of peptides. METHOD: We performed an organized toxicity and search of available literature using PubMed, Google Scholar, Medline, EMBASE, Reaxys and Scopus databases. All the relevant citations including research and review articles about the toxicity of biologically active peptides were evaluated and gathered in this study. RESULT: Biological peptides are widely used in the daily routine ranging from food production to the cosmetics industry and also they have a beneficial role in the treatment and prevention of different diseases. These peptides are manufactured by both chemical and biotechnological techniques, which show negligible toxicity, however, some naturally occurring peptides and enzymes may induce high toxicity. Depending upon the demand and expected use in the food or pharmaceutical industry, we need different approaches to acertain the safety of these peptides preferentially through in silico methods. CONCLUSION: Intestinal wall disruption, erythrocytes and lymphocytes toxicity, free radical production, enzymopathic and immunopathic tissue damage and cytotoxicity due to the consumption of peptides are the main problems in the biological system that lead to various complicated disorders. Therefore, before considering biologically active peptides for food production and for therapeutic purpose, it is first necessary to evaluate the immunogenicity and toxicities of peptides. PMID- 29468977 TI - The Development of New Factor Xa Inhibitors Based on Amide Synthesis. AB - BACKGROUND: Factor Xa (FXa) is known to play a central role in blood coagulation cascade and considered to be one of the most attractive targets for oral anticoagulants of new generation. OBJECTIVE: Our approach for the development of directly acting oral anticoagulants (DOAC), FXa inhibitors was demonstrated in this work. METHOD: Chemical synthesis is the base of our approach for the development of potential inhibitors. In this work, the substances like R1-(CONH) R2-(CONH)-R3 are being developed, using previously described docking and screening methods, where R1, R2 and R3 are some chemical groups and (CONH) are amide bonds connecting R1, R2 and R3. The direction of amide bond (CONH) could be arbitrary for R1, R2 and R2, R3. RESULTS: Chemical modifications were made in the frame of the results, taking into account the structure of FXa, chemical synthesis capabilities, as well as patentability of the target compounds. Subnanomolar potency of several developed compounds was achieved. Several analyzers and various testing-suites have been used to measure the concentration that doubled the prothrombin time (PTx2). Moreover, in human plasma the PTx2 concentration of the compound 217 (DD217) turned out to be 80+/-20 nM. The compound efficacy has proved by in vivo assays including oral administrations in rats, rabbits and monkeys. CONCLUSION: The pharmacodynamic profile of DD217 for oral administration in cynomolgus monkeys proves the efficacy of the compound, which makes it promising for the future preclinical trials. PMID- 29468978 TI - Comparing effectiveness of a combined herbal drug based on Echium amoenum with Citalopram in the treatment of Major Depressive Disorder. AB - BACKGROUND: According to new studies, only 60% of depressed patients respond to pharmaceutical treatment while suffering from their side effects. Natural products as adjuvant or alternative therapies should be examined to find safer and more effective ways to cope with depression. OBJECTIVE: Finding out the potential benefits of a combined herbal drug based on Echium amoenum compared with citalopram in the treatment of Major Depressive Disorder. DESIGN AND SETTING: In psychiatry clinics of Mashhad University of Medical Sciences, 50 patients who met the criteria for Major Depressive Disorder based on DSM-5 were studied in a parallel randomized controlled trial. INTERVENTION: Subjects were randomly assigned to receive Echium amoenum compound syrup (EACS) or citalopram tablet for 8 weeks. OUTCOME MEASURES: The efficacy of treatments and recurrence of disease were surveyed and compared according to Hamilton depression rating scale at weeks 0, 4, 8, 12. RESULTS: Patients in both groups of citalopram and EACS showed remarkable reduction in scores of Hamilton questionnaire. At the eighth week of treatment the mean scores in EACS group was significantly lower than citalopram group (p-value = 0.03). 52% of patients suffered from various complications in citalopram group while just 12% of patients in EACS group reported few complications. CONCLUSION: Clinical efficacy of this herbal drug was significantly higher than citalopram, and complications were also less and lower in EACS group. Further studies with larger groups and para-clinical assessments such as serologic tests and QEEG would improve our understanding of the impacts and mechanisms of EACS. PMID- 29468979 TI - Potentiation of Warfarin Associated with Salsalate Therapy Resulting in Bleeding. AB - BACKGROUND: Salsalate may offer many advantages over other non-steroidal antiinflammatory agents in patients taking warfarin, however a drug-drug interaction may occur which has not been reported in the medical literature or by the manufacturer of salsalate. OBJECTIVE: To report a case of warfarin potentiation associated with salsalate treatment, which resulted in bleeding. METHOD: Clinical review of the course of a patient, who was stable on warfarin when salsalate therapy was added for chronic pain. CASE REPORT: A patient taking stable doses of warfarin for over 1 year (with good control) was prescribed salsalate 3 g/day for pain in his knee and lower back. Approximately 1 month later he presents to the anticoagulation clinic with bruising and an International Normalized Ratio (INR) of 6.8. The patient had a good response to his salsalate therapy and wanted to continue it. The warfarin was held for 3 days and dose lowered by 50 %. His bruising then subsided and he had good control of his warfarin therapy with INRs ranging from 1.9 to 2.2 over the next 4 months. The patient was then lost to follow up. CONCLUSION: This case illustrates a strong association between starting salsalate and subsequent potentiation of warfarin, which heretofore has not been reported in the medical literature. PMID- 29468980 TI - Updates on GMSCs Treatment for Autoimmune Diseases. AB - BACKGROUND: Autoimmune disease is a refractory disease. Accumulating Evidence has revealed that the manipulation of mesenchymal stem cells may have the potential to control or even treat autoimmune diseases. Human gingiva-derived mesenchymal stem cells (GMSCs) are emerging as a new line of mesenchymal stem cells that have displayed some potential advantages in controlling and treating autoimmune diseases. OBJECTIVE: In this review, we briefly update the current understanding on the biology of GMSCs and their effects on preventing and treating autoimmune diseases. CONCLUSION: The availability of gingival mesenchymal stem cells (GMSCs), together with their potent capacity of multi-directional differentiation and inflammatory modulation, making GMSCs an ideal subtype of MSCs in treating autoimmune disease.

PMID- 29468981 TI - Lenvatinib in the Therapy of Aggressive Thyroid Cancer: State of the Art and New Perspectives with Patents Recently Applied. AB - BACKGROUND AND OBJECTIVE: Lenvatinib is an oral, multitargeted Tyrosine Kinase Inhibitor (TKI) of Vascular Endothelial Growth Factor Receptors (VEGFR1-VEGFR3), fibroblast growth factor receptors (FGFR1-FGFR4), Platelet-Derived Growth Factor Receptor (PDGFR)alpha, rearranged during transfection (RET), and v-kit (KIT) signaling networks implicated in tumor angiogenesis. METHOD: Here, we review the scientific literature about lenvatinib in the treatment of thyroid cancer. RESULTS: In vitro studies have shown antineoplastic activity of lenvatinib in Differentiated Thyroid Cancer (DTC), mainly because of its antiangiogenetic effects, but a slight effect on thyroid cancer cell proliferation has been shown. In vivo Phase II, and Phase III studies in patients with aggressive DTC not responsive to radioiodine, have shown that lenvatinib administration was associated with an amelioration in Progression-Free Survival (PFS) with respect to placebo (median PFS 18.2 vs. 3.6 months). However, overall survival was not significantly changed. Lenvatinib is also effective in patients resistant to sorafenib as salvage therapy. Adverse effects of any grade occur in more than 40% of lenvatinib-treated patients, mainly hypertension, diarrhea, asthenia or fatigue, nausea, decreased appetite, and decreased weight. Discontinuations of the therapy because of adverse effects occur in about 14% of patients. Moreover, deaths considered to be drug-related can occur. CONCLUSION: On the basis of the above-mentioned considerations, it is necessary to prove the effectiveness of lenvatinib in the context of associated moderate to severe toxicities requiring frequent dose reduction and delays, and for this reason, many interesting patents have been recently applied. PMID- 29468982 TI - Novel Patents Targeting Interleukin-17A; Implications in Cancer and Inflammation. AB - BACKGROUND: IL-17A is a founding member of the IL-17 family that has been implicated in the pathogenesis of inflammatory-associated diseases such as cancer and autoimmune disease. In cancer, IL-17A participates in many key events for tumor development, in part by affecting innate and adaptive immune system and also by direct modulation of many pro-tumor events. Moreover, IL-17A dysregulation at the site of inflammation is associated with rheumatoid arthritis, multiple sclerosis, psoriasis, among others. IL-17A has emerged as a topic of interest and is under profound investigation for its involvement in several types of inflammatory-associated diseases. OBJECTIVE: This review aims to present an overview of the state of the art of IL-17A role in cancer and inflammation, as well as to describe recent patents targeting IL-17A with relevant clinical and biological properties for the prevention and treatment of cancer and inflammatory diseases. METHODS: Relevant information was obtained by searching in PubMed using IL-17A or IL-17, cancer and inflammation as keywords, while relevant patents were obtained mainly from Google Patents. RESULTS: Literature data indicated IL-17A as important biomolecule in the physiopathology of cancer and inflammatory diseases. Whereas, novel patents (2010 to 2017) targeting IL-17A are focused mainly on describing strategies to modulate IL-17A per se, co-modulation by bispecific antibodies to blocking IL-17A and important cytokines for IL-17A functions, upstream mechanisms and compounds to regulate IL 17A expression. CONCLUSION: The promising effects of patented agents against IL 17A may open new opportunities to therapeutic intervention targeting at different levels of involvement in the pathogenesis of cancer and inflammatory diseases. PMID- 29468983 TI - Synthesis and DFT Study on Hantzsch Reaction to Produce Asymmetrical Compounds of 1,4-Dihydropyridine Derivatives for P-Glycoprotein Inhibition as Anticancer Agent. AB - BACKGROUND: P-glycoprotein (P-gp) causes the efflux of cancer chemotherapy drugs from tumor cells, so its inhibition can be one target for designing and synthesis of new anticancer drugs. OBJECTIVE: In this study, new compounds of 1,4 dihydropyridine (DHP) were recommended as inhibitors of P-gp. METHODS: We synthesized new symmetrical DHP with 36% - 43% yield by the reaction of new reactants. In biological studies, these compounds have high lipophilicity, and thus low water solubility. Four reactants I with different reactivity was computed and compared using DFT study. The LUMO-map was differently distributed on each reactant. Amine intermediate underwent tautomerism as a transition state and it seems to play important role in reaction progress. Calculations were performed to select suitable reactants. RESULTS: Two different reactants I, including one polar group and a non-polar group, were used to produce asymmetric compounds with 49% - 60% yield. These asymmetric DHPs were more soluble than symmetric DHPs. In the final step, another selected symmetric product (by the elimination of chlorine atom) was synthesized in high yield (74%) by using DFT study. CONCLUSION: In this study, selected reactants by DFT calculation have increased the yield of reaction from 36% to 74% without any catalyst. The diversity of products is a noticeable topic. Racemic asymmetric compounds with R and S enantiomers have the potential for enantiomeric separation. Each of these enantiomers could have a different physiological effect. PMID- 29468984 TI - VaD - An Integrated Framework for Cognitive Rehabilitation. AB - BACKGROUND & OBJECTIVE: Vascular dementia is the second most common cause of dementia, with clinical features that depend on neural substrates affected by the vascular lesions. Like most neurological disorders, it involves alterations that range from the molecular level to neuronal networks. Such alterations begin as compensatory mechanisms that reshape every subsystem involved in the brain's homeostasis. Although there have been recent huge advances in understanding the pathophysiology of cognitive dysfunction, a suitable therapeutic approach to vascular dementia remains elusive. Pharmacological interventions have failed to sustainably improve cognitive function, and it is a well-known fact that there is a need to change the current view for providing neuroprotection and enhancing neurorecovery after stroke. Studies regarding cognitive training are also faced with the difficulty of drawing up protocols that can embrace a holistic approach in cognitively impaired patients. CONCLUSION: This review will present a brief synthesis of current results from basic research data and clinical studies regarding pharmacological and non-pharmacological interventions in vascular dementia and will offer an integrated view from the perspective of systems biology. PMID- 29468985 TI - The Role of Neurohypophyseal Hormones Vasopressin and Oxytocin in Neuropsychiatric Disorders. AB - BACKGROUND AND OBJECTIVE: Although the neurohypophyseal hormones vasopressin (VP) and oxytocin (OT) are mostly known for their role respectively in antidiuresis, and in labour, lactation and maternal behavior, both might exert widespread influences either on emotion and cognition in healthy subjects, showing some gender-related differences. They interact with each other facilitating shifts between positive socially- oriented and defensive states. In fact, VP amplifies the reactivity to stressors showing also beneficial effects on attention, verbal learning as well as memory, whereas OT reduces the amplitude of the stress response, improves emotion processing, and can play a negative effect on memory and verbal learning in healthy individuals. Several data indicate the possible involvement of these neuropeptides in the pathophysiology of psychiatric conditions involving social interactions, such as autism, as well as in schizophrenia and depression. The aim of this paper is to review the literature relating to the role played by neurohypophyseal hormones in neuropsychiatric disorders. METHODS: We analyzed the best of published literature dealing with the relationships between neurohypophyseal hormones and neuropsychiatric conditions like autism (AD), major depressive disorder (MDD), bipolar disorder (BD) and schozophrenia, identifying keywords and MeSH terms in Pubmed and then searching them. The last search was performed on December 2017. RESULTS: Several studies indicate a role played by OT and VP in AD, schizophrenia, MDD and BD. Even if conflicting data have been reported, several mechanisms may be involved in these behavioral diseases, such as differences in aminoacid sequence and peptide biological activity, neurotransmission and genetic disorders involving OT and VP receptors. CONCLUSION: The involvment of VP and OT in neurpopsychiatric disorders can support a possible beneficial therapy with OT or with VP antagonists. The target may be obtained using effective drug delivery methods as well as the association with other drugs. PMID- 29468986 TI - Increased Endothelial Dysfunction and Insulin Resistance in Patients with Klinefelter Syndrome. AB - BACKGROUND AND OBJECTIVE: Patients with Klinefelter Syndrome (KS) have increased cardiometabolic risk however the pathogenesis is not clear. We investigated the presence of endothelial dysfunction, insulin resistance and inflammation in an unconfounded population of KS. METHODS: A total of 32 patients with KS (mean age 21.59 +/- 1.66 years) and 33 healthy control subjects (mean age: 22.15 +/- 1.03 years) were enrolled. The demographic parameters, Asymmetric dimethylarginine (ADMA), homeostatic model assessment of insulin resistance (HOMA-IR) index and highsensitivity C-reactive protein (hs-CRP) levels were measured. RESULTS: The patients had higher Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH), insulin, HOMA-IR and ADMA levels (p < 0.001 for all) and lower High Density Lipoprotein Cholesterol (HDL-C) and total testosterone levels (p=0.002 and p<0.001, respectively), compared to the healthy controls. Total testosterone levels were significantly negatively correlated to ADMA (r = - 0.479, p < 0,001), hs-CRP (r = -0.291, p = 0.034) and positively correlated to HDL-C (r = 0.429, p = 0.001) levels. The multivariate analysis has shown that total testosterone (beta = -0.412, p = 0.001) and TG (beta = 0.332, p = 0.009) levels were the significant independent determinants of the plasma ADMA levels. CONCLUSION: The results of the present study show that endothelial dysfunction and insulin resistance are prevalent even in the very young subjects with KS, who have no metabolic or cardiac problems at present. Also, hypogonadism seems to play an important role for increased cardiometabolic risk in patients with KS. PMID- 29468987 TI - Antithyroid Drugs Inactivate TSH Binding to the TSH Receptor by their Reducing Action. AB - : Backgroud and Objective: Antithyroid drugs (ATDs) [methylmercaptoimidazole (MMI) and propylthiouracil (PTU) ] are used to treat hyperthyroidism in Graves' disease. The effect of ATDs and reducing agents (mercaptoethanol, dithiothreitol and cysteine) on bovine (b) TSH binding to human (h) and porcine (p) TSH receptor (R) was examined. METHODS AND RESULTS: (1) ATDs was pre-incubated with hTSHR coated tube for 1- 4 h, washed free of ATDs, and then 125I-bTSH binding to hTSHR after 1 h incubation was examined. MMI (10-40 mM) decreased 125I-bTSH binding in a dose-dependent manner and binding decreased proportionally as preincubation time increased from 1 to 4 h. PTU (10mM) slightly decreased binding, When reducing agents were pre-incubated with hTSHR for 2 h, 125I-bTSH binding similarly decreased. (2) Porcine thyroid membrane was pre-incubated with both agents for 2 h. Then, the washed or unwashed membrane was incubated with 125I bTSH for 1 h. 125I-bTSH binding in both methods decreased. (3) When the effect of ATDs or reducing agents on the biological activity of 125I-bTSH and thyroid stimulating antibody (TSAb) was examined after gel-filtration of 125I-bTSH- and TSAb- treated with both reagents for 1 h, no inactivation was observed. (4) ATDs showed similar reducing action as reducing agents because iodine (I+) was reduced to I- by ATDs. CONCLUSION: ATDs inactivate the TSH-binding site of TSHR by reduction, although ATDs do not inactivate bTSH and TSAb activity. This suggests that TSAb would not stimulate the thyroid due to the inactivation of the TSHR when ATDs are administered to patients with Graves' disease. PMID- 29468988 TI - COX-2 in Radiotherapy: A Potential Target for Radioprotection and Radiosensitization. AB - BACKGROUND: Each year, millions of people die from cancer. Radiotherapy is one of the main treatment strategies for cancer patients. Despite the beneficial roles of treatment with radiation, several side effects may threaten normal tissues of patients in the years after treatment. DISCUSSION: Moreover, high incidences of second primary cancers may reduce therapeutic ratio of radiotherapy. The search for appropriate targets of radiosensitization of tumor cells as well as radioprotection of normal tissues is one of the most interesting aims in radiobiology. Cyclooxygenase-2 (COX-2), as an inflammatory mediator has attracted interests for both aims. COX-2 activity is associated with ROS production and inflammatory signs in normal tissues. These effects further amplify radiation toxicity in irradiated cells as well as adjacent cells through a phenomenon known as Bystander effect. Increased COX-2 expression in distant non-irradiated tissues causes oxidative DNA damage and elevated cancer risk. Moreover, in tumors, the activation of this enzyme can increase resistance of malignant cells to radiotherapy. Hence, the inhibition of COX-2 has been proposed for better therapeutic response and amelioration of normal tissues. Celecoxib is one of the most studied COX-2 inhibitor for radiosensitization and radioprotection, while some other inhibitors have shown interesting results. CONCLUSION: In this review, we describe the role of COX-2 in radiation normal tissue injury as well as irradiated bystander and non-targeted cells. In addition, mechanisms of COX-2 induced tumor resistance to radiotherapy and the potential role of COX-2 inhibition are discussed.

AB - OBJECTIVES: The aim of this study was to investigate the association between dairy product consumption and plasma inflammatory biomarkers levels among a representative sample of Brazilian adults from Sao Paulo City. METHODS: Data were acquired from the Health Survey for Sao Paulo, a cross-sectional population-based study. All individuals 20 to 59 y of age with complete food consumption information (24-h dietary recall and food frequency questionnaire) and blood sample analysis were included (N = 259). The sample was separated into two groups according to systemic inflammatory pattern considering plasma levels of C reactive protein; tumor necrosis factor-alpha; soluble intracellular adhesion molecule; soluble vascular cell adhesion molecule, monocyte chemoattractant protein; interleukin-1beta, -6, -8, -10, and -12; adiponectin; leptin; and homocysteine. Multiple logistic regression tests were conducted to estimate the odds ratio for the inflammatory cluster across tertiles of dairy consumption. RESULTS: When adjusted by age, smoking status, and energy intake the odds ratio for the inflammatory cluster group in the highest tertile of yogurt consumption was 0.34 (95% confidence interval [CI], 0.14-0.81) relative to the reference tertile, demonstrating also a linear effect (Ptrend = 0.015). Cheese consumption exhibited an odds ratio of 2.49 (95% CI, 1.09-5.75) relative to the reference. CONCLUSIONS: Increasing yogurt consumption might have a protective effect on inflammation, whereas cheese consumption appears to be associated with a proinflammatory status. The results of the present study aggregate a new perspective on existing evidence demonstrating the importance of assessing the contribution of dairy products on diet and their effect on the development of non communicable diseases and associated risk factors. PMID- 29469010 TI - Effect of blood thiamine concentrations on mortality: Influence of nutritional status. AB - OBJECTIVE: To test the hypothesis that low blood thiamine concentrations in malnourished critically ill children are associated with higher risk of 30-d mortality. METHODS: Prospective cohort study in 202 consecutively admitted children who had whole blood thiamine concentrations assessed on admission and on days 5 and 10 of intensive care unit (ICU) stay. The primary outcome variable was 30-d mortality. Mean blood thiamine concentrations within the first 10 d of ICU stay, age, sex, malnutrition, C-reactive protein concentration, Pediatric Index of Mortality 2 score, and severe sepsis/septic shock were the main potential exposure variables for outcome. RESULTS: Thiamine deficiency was detected in 61 patients within the first 10 d of ICU stay, 57 cases being diagnosed on admission and 4 new cases on the 5th d. C-reactive protein concentration during ICU stay was independently associated with decreased blood thiamine concentrations (P = 0.003). There was a significant statistical interaction between mean blood thiamine concentrations and malnutrition on the risk of 30-d mortality (P = 0.002). In an adjusted analysis, mean blood thiamine concentrations were associated with a decrease in the mortality risk in malnourished patients (odds ratio = 0.85; 95% confidence interval [CI]: 0.73-0.98; P = 0.029), whereas no effect was noted for well-nourished patients (odds ratio: 1.03; 95% CI: 0.94 1.13; P = 0.46). CONCLUSIONS: Blood thiamine concentration probably has a protective effect on the risk of 30-d mortality in malnourished patients but not in those who were well nourished. PMID- 29469011 TI - The effects of resistance training of swallowing muscles on dysphagia in older people: A cluster, randomized, controlled trial. AB - OBJECTIVE: This study examined the effects of resistance training of swallowing muscles in community-dwelling older individuals with dysphagia. METHODS: A cluster randomized controlled trial was performed in day-service and day-care facilities. The participants were older (>=65 y) community-dwelling individuals with dysphagia. The intervention group performed a tongue resistance exercise and a head flexion exercise against manual resistance. Both groups received a brochure on dysphagia rehabilitation. The primary endpoint was an improvement in dysphagia assessed by the Eating Assessment Tool (EAT-10) score. Tongue pressure was the secondary endpoint. RESULTS: Participants included 47 men and 57 women, with a mean age +/- standard deviation of 80 +/- 7 y. At baseline, the median EAT 10 score was 7 (interquartile range, 5-12). A total of 91 patients, 43 in the intervention group (8 clusters) versus 48 in the control group (11 clusters), were assessed postintervention. The percentage of participants with EAT-10 scores <3 was not statistically significantly different between the two groups (intervention group, 23% versus control group, 19%, P = 0.598). Postintervention median EAT-10 scores were 6 (interquartile range, 3-10) in each group (P = 0.665) and mean tongue pressure was 23.9 +/- 10.0 versus 25.9 +/- 10.9 kPa (P = 0.376). The intervention did not significantly affect the EAT-10 score or tongue pressure in a mixed effects random intercept model. The Mini Nutritional Assessment Short Form score correlated significantly with the postintervention EAT-10 score. CONCLUSIONS: Resistance training of swallowing muscles did not improve dysphagia in this study. Better nutritional status correlated independently with improved swallowing function. PMID- 29469012 TI - Nutritional status and postoperative outcomes in patients with gastrointestinal cancer in Vietnam: a retrospective cohort study. AB - BACKGROUND: Nutritional support for surgical care is crucial because hospital malnutrition is rather common. However, low- and middle-income countries have not adequately addressed nutritional management of surgical patients. To highlight need for nutritional management in surgical patients, the present study aimed to describe preoperative nutritional status in patients who underwent gastrointestinal cancer surgery in Vietnam and to investigate the relationship between preoperative malnutrition and adverse outcomes, such as postoperative complications and prolonged length of hospital stay. METHODS: We reviewed medical records of patients who underwent a major curative surgery for gastrointestinal cancer at the national hospital in Ho Chi Minh City, Vietnam. We identified preoperative malnutrition based on body mass index and serum albumin level, and postoperative complications in the first 30 d postoperative. We estimated the relative influence of malnutrition on complications and length of hospital stay using multivariate regression models. RESULTS: Of 459 eligible patients, 63% had colorectal cancer, 33% gastric cancer, and 4% esophageal cancer. The prevalence of malnutrition was 19%. No patients died during hospitalization; however, 26% developed complications after surgery. The average length of hospital stay was 14 d. After controlling for potential confounders, preoperative malnutrition was associated with an increased risk of postoperative complications (odds ratio = 1.97) and prolonged hospital stay (2.8 d). CONCLUSIONS: Preoperative malnutrition affects surgical outcomes among patients with gastrointestinal cancer in Vietnam. We recommend implementing preoperative nutritional interventions to achieve better outcomes among surgical cancer patients. PMID- 29469013 TI - Intermittent food restriction in female rats induces SREBP high expression in hypothalamus and immediately postfasting hyperphagia. AB - OBJECTIVE: We investigated the effect of intermittent food restriction (IFR) cycles on hypothalamic expression of lipogenic proteins and induction of overeating. METHODS: Female Wistar rats were distributed in three groups: free access to feed (control, C), 2 d feed restriction at 50% of C intake followed by 3 d (restricted 3, R3) or 5 d (restricted 5, R5) ad libitum feeding. After 6 wk, the rats were submitted to euthanasia and collected the hypothalamus and blood. The deposits of retroperitoneal, mesenteric, and gonadal fat were weighed. The expression of the mRNA for sterol regulatory element binding protein (SREBP) 1c and 2 and acetyl-CoA carboxylase in the hypothalamus were determined by real-time polymerase chain reaction, and glucose and triacylglycerol were evaluated by a commercial kit. Body mass and food intake were measured daily. RESULTS: IFR promoted increased expression of SREBP-2 in both treated groups and, in R5, increased expression of SREBP-1c. The serum triacylglycerol, mesenteric deposit, and total fat content were higher in R3. Neither of the treatment intervals altered the expression of the mRNA of acetyl-CoA carboxylase enzyme but induced hyperglycemia and higher food intake immediately after food restriction. CONCLUSION: IFR affected the expression of SREBP-1c in R5 and SREBP-2 in the hypothalamus and caused overeating immediately after fasting in both groups. We suggest that hypothalamic and peripheral alterations, coupled with compulsive eating behavior in the ad libitum period, indicate risks for diabetes mellitus and recovery of body mass after interruption of IFR. PMID- 29469014 TI - Effect of mineral status and glucocorticoid use on bone mineral density in patients with Crohn's disease. AB - OBJECTIVES: Crohn's disease (CD) is a condition that is characterized by chronic inflammation. The presence of multifactorial pathogenesis that results from inflammation is associated with low micronutrient consumption and glucocorticoid use, which may be related to bone health. This study aimed to evaluate the relationship between dietary mineral intake and glucocorticoid use in bone mineral density (BMD) in patients with CD. METHODS: A cross-sectional study of 62 patients with CD ages 20 y to 40 y measured their macro- and micronutrient intake with a 3-d food record. The lumbar spine and femoral neck BMDs were determined using a bone densitometry technique. The C-reactive protein (CRP) levels and erythrocyte sedimentation rate (ESR) values were also noted. RESULTS: Dietary intake of calcium, zinc, and magnesium was below the reference values but the phosphorus intake level was within the normal value range. Patients with osteopenia and osteoporosis accounted for 17.7% and 14.5%, respectively, of the total number of participants. Significant bone loss was found in 22.6% of patients taking glucocorticoid medications. BMD was significantly reduced and also observed in patients in the active phase of their disease. Zinc and calcium intakes were found to be correlated with reduced femoral neck BMD. The mean CRP and ESR values were above the normal ranges. Significant differences in age and ESR were observed between patients with normal and reduced BMD (P <0.05). CONCLUSIONS: Low calcium and zinc intake, glucocorticoid use, and active disease phase are favorable conditions for bone loss in patients with Crohn's disease. PMID- 29469015 TI - Do celiac disease and non-celiac gluten sensitivity have the same effects on reproductive disorders? AB - OBJECTIVES: The wide spectrum of clinical symptoms of celiac disease (CD) is partly due to the malnourished state caused by the malabsorption of micro- and macronutrients. It has been suggested that fertility problems and obstetric complications may be a consequence of the endocrine disorders caused by selective nutrient deficiencies. The same selective nutrient deficiencies as in CD could be a reason for fertility problems in non-celiac gluten sensitivity (NCGS). The aim of this study was to investigate the effect of nutrient deficiencies in CD and NCGS on fertility problems. METHOD: A literature review of fertility problems in men and women and nutrient deficiencies associated with CD and NCGS, was performed up to May 2017. RESULTS: The same selective nutrient deficiencies (folate, iron, vitamin B12, and vitamin D) in CD and NCGS could be a reason for fertility problems. CONCLUSIONS: CD is postulated to be considered in the preconceptional screening of patients with reproductive disorders, but for non celiac gluten sensitivity, the effect on fertility is not yet proven. PMID- 29469016 TI - The potential health and economic effects of plant-based food patterns in Belgium and the United Kingdom. AB - OBJECTIVE: Policymakers increasingly require scientific evidence on both health and economic consequences of different nutritional patterns. The aim of this study was to assess health and economic effects of Mediterranean and soy containing diets. Selected countries were Belgium and the United Kingdom. METHODS: Cost-effectiveness of these plant-based food patterns was assessed in comparison with a "conventional" diet using an age- and sex-dependent prediction model. The model allowed the prediction of health outcomes and related health care costs for the food patterns over 20 y. A societal perspective was applied for cost calculation and health outcomes were expressed in quality-adjusted life years (QALYs). RESULTS: For Belgium, a soy-containing diet is estimated to lead to 202 QALYs and 107 QALYs per 1000 women and men, respectively, whereas societal savings of ?2 146 000 and ?1 653 000 are predicted. For the United Kingdom, a gain of 159 QALYs and 100 QALYs per 1000 women and men, respectively, is estimated, as are a prediction of savings of L1 580 000 and L1 606 000. For the Mediterranean diet in the corresponding estimates for Belgium are 184 QALYs and 148 QALYs per 1000 women and men, respectively, and savings of ?1 618 000 and ?1 595 000. For the United Kingdom, these are 122 QALYs and 110 QALYs per 1000 women and men, respectively, and savings of L1 155 000 and L1 046 000, respectively. CONCLUSION: A wider implementation of plant-based eating would lead to large net economic gains for society and improved health outcomes for the population. PMID- 29469017 TI - Psychopathological correlates of eating behavior among Portuguese undergraduate students. AB - OBJECTIVES: The aim of this study was to explore the relationships between eating behavior dimensions and psychopathological symptoms among Portuguese undergraduate students. METHODS: We studied 258 participants (62.4% women) regarding eating behavior dimensions (emotional, external and binge eating, flexible and rigid control of eating behavior, and eating self-efficacy), psychopathological distress (as assessed by the Brief Symptom Inventory), and body mass index. In addition to studying bivariate associations between eating behavior dimensions and psychopathological subscales and indexes, what we believe to be a novel analytical approach, considering simultaneously the effects of the overall level of psychopathological distress and the relevance of specific symptoms on the eating behavior dimensions. RESULTS: Emotional, external, and binge eating had positive correlations with psychopathological symptomatology, whereas eating self-efficacy was negatively associated. CONCLUSIONS: Multivariate analysis showed that the overall level of psychopathological distress (combined with body mass index, among women) had a larger effect on eating behavior than the relevance of specific symptoms. PMID- 29469018 TI - Evaluation of malnutrition development risk in hospitalized children. AB - OBJECTIVES: Many screening methods, such as the Screening Tool Risk on Nutritional Status and Growth (STRONGkids) and the Pediatric Yorkhill Malnutrition Score (PYMS), have been developed to detect malnutrition in pediatric patients. We aimed to explore the prevalence of malnutrition risk in hospitalized children via symptoms and identification of contributing factors, and to examine the efficacy of malnutrition screening tools for hospitalized children. METHODS: STRONGkids and PYMS were applied to 1513 inpatients at 37 hospitals in 26 cities from different regions of Turkey. Physical measurements were collected at hospital admission and at discharge. z-Scores of height-for age, weight-for-age, weight-for-height, and body mass index-for-age were calculated. RESULTS: Overall, 1513 patients were included in the study. A body mass index standard deviation score of less than -2 was present in 9.5% of the study population at hospital admission, whereas 11.2% of the participants had a weight-for-length/height score of less than -2 at hospital admission. According to STRONGkids results, the proportion of the patients with an underlying chronic disease was higher for the patients at high risk of malnutrition than for the patients at medium or low risk (91% compared with 47% or 45%, respectively). PYMS results indicated that patients at high risk of malnutrition have more chronic diseases (75%) than the patients at medium or low risk of malnutrition (55% and 44%, respectively). CONCLUSIONS: Use of anthropometric measurements in addition to screening tools to identify hospital malnutrition (such as PYMS, STRONGkids) will prevent some nutritional risk patients from being overlooked. PMID- 29469019 TI - Longitudinal adherence to a dietary pattern and risk of depressive symptoms: the Furukawa Nutrition and Health Study. AB - OBJECTIVE: We explored the association of 3-year adherence to a dietary pattern based on nutrients that may be related to mood with the development of depressive symptoms in Japanese employees. METHODS: Participants were 903 employees free from depressive symptoms at baseline and who attended the 3-year follow-up. Participants with depressive symptoms were defined as those with a score >=16 on the Center for Epidemiologic Studies Depression Scale. Dietary patterns were derived using reduced-rank regression at baseline and at the 3-year follow-up survey using a validated, self-administered diet history questionnaire. Based on changes in dietary pattern scores between baseline and follow-up surveys, participants were categorized into four groups: Maintained high scores, improved scores, decreased scores, and maintained low scores. Logistic regression was used to estimate odds ratios of depressive symptoms according to changes in dietary pattern scores. RESULTS: Maintaining high or improving adherence to a diet rich in vegetables, mushrooms, seaweeds, soybean products, green tea, potatoes, fruits, and fish and low in rice over 3 y was associated with a decreased risk of depressive symptoms. The multivariable-adjusted odds ratio (95% confidence intervals) of developing depressive symptoms for maintained high scores versus maintained low scores was 0.57 (0.35-0.93) and for improved scores versus maintained low scores was 0.54 (0.29-1.01). The association with the severe depressive status was more pronounced. CONCLUSION: Maintaining high or improving adherence to a dietary pattern derived by reduced-rank regression is associated with a lower risk of depression among Japanese employees. PMID- 29469020 TI - Changes in nutritional state and dysphagia in stroke patients monitored during a 14-d period in a Burkina Faso hospital setting. AB - INTRODUCTION: Dysphagia and undernourishment are common in cerebrovascular accident (stroke) patients in developed countries. Despite the dietary transition, there is little information available in Africa on this topic. This study aims to assess the prevalence of undernourishment and dysphagia in stroke patients in two Burkina Faso teaching hospitals at a starting point (D0), on the eighth day, and on the 14th (D14) and to specify factors related to undernourishment at day 14. METHODOLOGY: The nutritional state of the patients was assessed using body mass index, triceps skinfold thickness, and mid-upper arm circumference. Dysphagia was identified using the Practical Aspiration Screening Schema. RESULTS: A total of 222 patients were included in the study. From D0 to D14, the prevalence of undernourishment increased from 25.2% to 31.0% and the prevalence of dysphagia decreased from 37.4% to 15.8%. All nutritional criteria worsened. In a multivariate analysis, undernourishment was more present at D14 for women (odds ratio [OR] = 7.01; 95% confidence interval [CI]: 1.51-32.56, P = 0.01) and was less present if weight (OR = 0.69; 95% CI: 0.60-0.79, P = 0.0001) or triceps skinfold thickness (OR = 0.85; 95% CI: 0.74-0.99, P = 0.03) were high at D0. CONCLUSION: The prevalence of undernourishment was high at D0 and increased during the monitoring period. It would be advisable to monitor patients' weight and triceps skinfold thickness, to optimize care for women and patients with low weight or triceps skinfold thickness at D0, to monitor dysphagia, and to inform patients, families, and relevant staff of nutritional concerns after a cerebrovascular accident. PMID- 29469021 TI - Perinatal and lifestyle factors mediate the association between maternal education and preschool children's weight status: the ToyBox study. AB - OBJECTIVE: This study aimed to explore the associations among perinatal, sociodemographic, and behavioral factors and preschool overweight/obesity. METHODS: Data were collected from 7541 European preschoolers in May/June 2012. Children's anthropometrics were measured, and parents self-reported all other data via questionnaires. Level of statistical significance was set at P <= 0.05. RESULTS: Certain perinatal factors (i.e., maternal prepregnancy overweight/obesity, maternal excess gestational weight gain, excess birth weight, and "rapid growth velocity"), children's energy balance-related behaviors (i.e., high sugar-sweetened beverage consumption, increased screen time, reduced active play time), family sociodemographic characteristics (i.e., Eastern or Southern Europe, low maternal and paternal education), and parental overweight/obesity were identified as correlates of preschoolers' overweight/obesity. Furthermore, maternal prepregnancy overweight/obesity, children's "rapid growth velocity," and increased screen time mediated by 21.2%, 12.5%, and 5.7%, respectively, the association between maternal education and preschoolers' body mass index. CONCLUSION: This study highlighted positive associations of preschooler's overweight/obesity with excess maternal prepregnancy and gestational weight gain, excess birth weight and "rapid growth velocity," Southern or Eastern European region, and parental overweight/obesity. Moreover, maternal prepregnancy overweight/obesity, children's "rapid growth velocity," and increased screen time partially mediated the association between maternal education and preschoolers' body mass index. The findings of the present study may support childhood obesity prevention initiatives, because vulnerable population groups and most specifically low-educated families should be prioritized. Among other fields, these intervention initiatives should also focus on the importance of normal prepregnancy maternal weight status, normal growth velocity during infancy, and retaining preschool children's screen time within recommendations. PMID- 29469022 TI - Obesity candidate genes, gestational weight gain, and body weight changes in pregnant women. AB - OBJECTIVE: To examine the associations of two obesity-associated genes, FTO (rs9939609) and GNB3 (rs5443) single nucleotide polymorphisms (SNPs), with early pregnancy body mass index, gestational weight gain, and postpartum weight retention. METHODS: Secondary data analysis of self-identified white (n = 580) and black (n = 194) women who participated in a randomized controlled trial (2009 2014) and provided a saliva sample of DNA. Bivariate relationships were assessed using analysis of variance. Multiple regression models assessed the relationship between outcomes and gene SNPs, controlling for income, parity, and smoking status. RESULTS: FTO and GNB3 gene associations with pregnancy weight were different by racial group and early pregnancy body mass index. Obese black women homozygote for the FTO risk allele (AA) had a higher gestational weight gain compared with non-risk homozygotes (TT) (P = 0.006). GNB3 non-risk CC homozygotes tended to have a lower gestational weight gain compared with heterozygotes (P = 0.05). White GNB3 C carriers tended to be heavier in early pregnancy (P <0.1) and GNB3 homozygote (TT) overweight women tended to have lower postpartum weight retention than C carriers. CONCLUSIONS: The FTO gene and possibly the GNB3 gene are associated with high gestational weight gain in obese black women. Obese carriers of the FTO risk allele gained 4.1 kg (AT) and 7.6 kg (TT) more than those without risk alleles. Overweight GNB3 heterozygotes (CT) gained 6.6 kg less than homozygotes (CC). Overweight or obese black women who have either risk variant are at risk for high gestational weight gain. PMID- 29469023 TI - Influence of a multidisciplinary protocol on nutritional status at diagnosis in amyotrophic lateral sclerosis. AB - OBJECTIVE: The aim of this study were to understand the influence of a multidisciplinary care protocol in amyotrophic lateral sclerosis (ALS) on the change in the delay of remission to the nutrition specialist and the initial nutritional status. METHODS: A cohort study was performed in 43 patients with ALS who were referred to the Nutrition Unit between April 2015 and April 2017. Anthropometric parameters and diagnostic times were collected, and the nutritional status was studied through subjective global assessment (SGA). Patients who were included before (control cohort [NoP]) and after (protocol cohort [P]) a multidisciplinary protocol were compared. The mean age of the participants was 66.79 y (10.86 y). Of the patients, 62.8% belonged to the protocol cohort. RESULTS: Patients who started the protocol had a lower delay in initial assessment by a nutrition specialist (P:2 [1-6] mo/NoP:12 [10-29] mo; P = 0.03). When the nutritional status was analyzed according to the SGA, more patients who did not initiate protocol were in the state of severe malnutrition (C) (P 22.2% versus NoP 60%; P = 0.01). Entry into the protocol was an independent protective factor of the presence of severe malnutrition at the beginning of the nutritional follow-up (odds ratio, 0.20; 95% confidence interval, 0.03-0.73; P = 0.02). CONCLUSIONS: The implementation of a multidisciplinary protocol in ALS allowed patients to present a lower percentage of severe malnutrition in an initial assessment by the nutrition specialist. This protocol is a protective factor for the presence of malnutrition at the beginning of support. PMID- 29469025 TI - Sleep duration and consumption of sugar-sweetened beverages and energy drinks among adolescents. AB - OBJECTIVE: To examine the relationship between sleep duration and consumption of sugar sweetened beverages (SSBs) and energy drinks (EDs) among adolescents. METHODS: Data on 9,473 adolescents aged 11-20 years were obtained from the 2015 cycle of the Ontario Student Drug Use and Health Survey, a province-wide and cross-sectional school based survey of students in middle and high school. Respondents self-reported their sleep duration and consumption of SSBs and EDs. Those who did not meet the age-appropriate sleep duration recommendation were considered short sleepers. RESULTS: Overall, 81.4% and 12.0% of respondents reported that they had at least one SSBs and EDs in the past week, respectively. Males were more likely than females to consume SSBs and EDs. High school students were more likely than those in middle school to report drinking EDs. After adjusting for multiple covariates, results from logistic regression analyses indicated that short sleep duration was associated with greater odds of SSB consumption in middle school students (odd ratio (OR) = 1.64, 95% confidence interval (CI) = 1.18-2.11), but not those in high school (OR = 1.06, 95% CI = 0.86-1.31). Short sleep duration was associated with greater odds of ED consumption in both middle (OR = 1.60, 95% CI = 1.10-2.34) and high school (OR = 1.78, 95% CI = 1.38-2.30) students. CONCLUSION: Short sleep duration was associated with consumption of EDs in middle and high school students and with SSBs in middle school students only. Future studies are needed to establish causality and to determine whether improving sleep patterns can reduce the consumption of SSBs and EDs among adolescents. PMID- 29469024 TI - Association between body composition and pulmonary function in children and young people with cystic fibrosis. AB - OBJECTIVES: Body mass index (BMI) has significant limitations when assessing nutritional status in pediatric patients with cystic fibrosis (CF). We evaluated whether measurements of lean body mass (LBM) and fat mass (FM) are more sensitive nutritional parameters by testing their association with pulmonary function in adolescent patients with CF. METHODS: Sixty-nine male and female adolescents with CF were studied (age: 14.5 +/- 2.3, BMI: 19.5 +/- 2.3 kg/m2). Dual-energy x-ray absorptiometry (DXA) was used to measure total and segmental (appendicular, truncal) body composition (FM, LBM bone mineral density, and content) as routine care to monitor bone health. Correlation and multiple regression analyses were performed to assess the association among body composition variables and forced expiratory volume in 1 s (FEV1). We also evaluated the influence of the F508del mutation on body composition. RESULTS: FEV1 was significantly associated with total (r = 0.68, P <0.001), truncal (r = 0.71, P <0.001), and appendicular (r = 0.67, P <0.001) LBM, whereas it was not associated with total (r = 0.02, P = 0.89) and truncal (r = 0.04, P = 0.77) FM. BMI had a significant but weaker correlation with FEV1 (r = 0.52, P <0.001) compared with LBM. LBM was the only significant predictor of FEV1 in fully adjusted regression models. CONCLUSIONS: LBM is a significant predictor of pulmonary function in CF adolescent patients. DXA scanning performed as part of routine bone health monitoring in CF can provide important body composition data relevant to clinical interventions that optimize nutritional status. DXA reference data for LBM in non-adult populations are needed to enhance diagnostic assessment and monitor clinical progression of CF. PMID- 29469026 TI - Effect of nutritional status on mortality in patients undergoing coronary artery bypass grafting. AB - OBJECTIVES: The prognostic effects of poor nutritional status and cardiac cachexia on coronary artery disease (CAD) are not clearly understood. A well accepted nutritional status parameter, the prognostic nutritional index (PNI), which was first demonstrated to be valuable in patients with cancer and those undergoing gastrointestinal surgery, was introduced to patients requiring coronary artery bypass grafting (CABG). The aim of the present study was to evaluate the prognostic value of PNI in patients with CAD undergoing CABG. METHODS: We evaluated the in-hospital and long-term (3-y) prognostic effect of PNI on 644 patients with CAD undergoing CABG. Baseline characteristics and outcomes were compared among the patients by PNI and categorized accordingly: Q1, Q2, Q3, and Q4. RESULTS: Patients with lower PNI had significantly higher in hospital and long-term mortality. Patients with lower PNI levels (Q1) had higher in-hospital mortality and had 12 times higher mortality rates than those with higher PNI levels (Q4). The higher PNI group had the lower rates and was used as the reference. Long-term mortality was higher in patients with lower PNI (Q1)-4.9 times higher than in the higher PNI group (Q4). In-hospital and long-term mortality rates were similar in the non-lower PNI groups (Q2-4). CONCLUSION: The present study demonstrated that PNI, calculated based on serum albumin level and lymphocyte count, is an independent prognostic factor for mortality in patients undergoing CABG. PMID- 29469028 TI - Effects of short-term dietary restriction and glutamine supplementation in vitro on the modulation of inflammatory properties. AB - OBJECTIVE: Dietary restriction (DR) is a nutritional intervention that exerts profound effects on biochemical and immunologic parameters, modulating some inflammatory properties. Glutamine (GLN) is a conditionally essential amino acid that can modulate inflammatory properties. However, there is a lack of data evaluating the effects of DR and GLN supplementation, especially in relation to inflammatory cytokine production and the expression of transcription factors such as nuclear factor (NF)-kappaB. METHODS: We subjected 3-mo-old male Balb/c mice to DR by reducing their food intake by 30%. DR animals lost weight and showed reduced levels of serum triacylglycerols, glucose, cholesterol, and calcium as well as a reduction in bone density. Additionally, blood, peritoneal, and spleen cellularity were reduced, lowering the number of peritoneal F4/80- and CD86 positive cells and the total number of splenic CD4- and CD8-positive cells. RESULTS: The production of interleukin (IL)-10 and the expression of NF-kappaB in splenic cells were not affected by DR or by GLN supplementation. However, peritoneal macrophages from DR animals showed reduced IL-12 and tumor necrosis factor-alpha production and increased IL-10 production with reduced phosphorylation of NF-kappaB expression. Additionally, GLN was able to modulate cytokine production by peritoneal cells from the control group, although no effects were observed in cells from the DR group. CONCLUSION: DR induces biochemical and immunologic changes, in particular by reducing IL-12 and tumor necrosis factor-alpha production by macrophages and clearly upregulating IL-10 production, whereas GLN supplementation did not modify these parameters in cells from DR animals. PMID- 29469027 TI - Reduced mortality risk by a polyphenol-rich diet: An analysis from the Moli-sani study. AB - OBJECTIVES: The effect of the polyphenol content of the human diet on mortality risk is not yet fully understood. The aim of this study was to evaluate the association of a polyphenol-rich diet with mortality rate and a possible mediation effect by inflammation, in what we believe to be a novel, holistic approach. METHODS: We analyzed 21 302 participants (10 980 women and 10 322 men, aged >=35 y) from the Moli-sani cohort. The participants were followed up for a median of 8.3 y. The European Prospective Investigation into Cancer and Nutrition food frequency questionnaire (FFQ) was used for dietary assessment. Flavonol, flavone, flavanone, flavanol, anthocyanin, isoflavone, and lignan intakes were calculated using European Food Information Resource-Bioactive Substances in Food Information Systems and the polyphenol antioxidant content (PAC)-score was constructed to assess the total content of these nutrients in the diet. RESULTS: Participants included in the highest quintile of intake of various polyphenol classes and subclasses presented a significant lower all-cause mortality risk compared with those in the lowest group of consumption (hazard ratio [HR] < 1; P <0.05). Cox regression analyses adjusted for potential confounders indicated that participants in higher quintiles of PAC-score had lower all-cause mortality risk (HR <1; P <0.05). When cause-specific mortality rates were considered, similar effects were observed for cardiocerebrovascular and cancer mortality (HR <1; P <0.05). CONCLUSIONS: The polyphenol content of the diet was associated with reduced mortality risk in a Mediterranean population, possibly through an antiinflammatory mechanism. PMID- 29469029 TI - Preclinical evaluation of degradation kinetics and elemental mapping of first- and second-generation bioresorbable magnesium scaffolds. AB - AIMS: Because vascular restoration therapy using bioresorbable vascular scaffolds (BRS) remains an appealing concept to restore vasoreactivity, an understanding of biodegradation remains paramount during preclinical testing. We therefore aimed to investigate the qualitative and temporal course of degradation of magnesium alloy-based bioresorbable vascular scaffolds in juvenile swine. METHODS AND RESULTS: Qualitative characterisation of biodegradation was performed in 41 DREAMS 1G up to three years, while degradation kinetics were acquired in 54 DREAMS 2G implanted into porcine coronary arteries for 28, 90 and 180 days, one and two years. Assessment of end product composition was achieved in DREAMS 2G at 180 days. Myocardium was examined, while an OCT attenuation score was derived at strut level from 180 days to two years in DREAMS 2G. Degradation of DREAMS entails two corrosive phases. At one year, 94.8% of the magnesium was bioabsorbed in DREAMS 2G and, at two years, magnesium was completely replaced by amorphous calcium phosphate. Von Kossa staining revealed variable peri-strut mineralisation at all time points and only small focal myocardial emboli observed in one animal in the 180 days cohort. Strut discontinuity density was low at 28 days (0.5+/ 0.57 per mm) and increased to a density above 7.5 per mm up to one year. OCT attenuation score correlated well with strut-based degradation analysis up to two years. CONCLUSIONS: While the current set of data supports vascular safety, clinical trials are warranted to prove the concept of vascular restoration following DREAMS implantation. PMID- 29469030 TI - The efficacy of early versus delayed P2Y12 inhibition in percutaneous coronary intervention for ST-elevation myocardial infarction: a systematic review and meta analysis. AB - AIMS: The aim of this meta-analysis was to compare the benefit of "early" vs. "delayed" P2Y12 inhibition in patients undergoing percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI). METHODS AND RESULTS: We conducted a meta-analysis including seven randomised controlled trials (RCTs) which compared early vs. delayed P2Y12inhibition in STEMI patients scheduled for PCI, providing data on major adverse cardiac events (MACE), all cause death, and major bleeding. The primary endpoint was MACE. Secondary endpoints included stent thrombosis and the use of GP IIb/IIIa inhibitors (GPI). All endpoints were analysed at the shortest follow-up available. A total of 9,648 patients were included ("early"=4,792, "delayed"=4,856). "Early" P2Y12 inhibition was associated with a significant reduction in MACE rate (OR 0.73, 95% CI: 0.61 0.88, p=0.0008), myocardial infarction (OR 0.71, 95% CI: 0.57-0.90, p=0.004), bail-out GPI use (OR 0.87, 95% CI: 0.75-1.00, p=0.04) and improved coronary reperfusion before PCI (OR for Thrombolysis In Myocardial Infarction [TIMI] flow grade 2-3=1.12, 95% CI: 1.00-1.26, p=0.04). Major bleeding was not increased (OR 0.87, 95% CI: 0.62-1.21, p=0.41). CONCLUSIONS: A strategy of early effective P2Y12 inhibition in PCI of STEMI appears to improve coronary reperfusion before PCI, and reduce MACE, MI and bail-out GPI use without increase of major bleeding.

PMID- 29469032 TI - Pregnancy in papillary thyroid cancer survivors AB - OBJECTIVE: To evaluate "papillary thyroid carcinoma-pregnancy" interaction among cancer survivors. MATERIAL AND METHODS: The clinical records of 8 pregnant women who received treatment for papillary thyroid cancer before their pregnancy were evaluated. Clinical features, pregnancy/perinatal outcomes and high-risk factors were compared with 45 controls who were randomly assigned from the institutional perinatal medicine database. RESULTS: Patients in the cancer group were older than the control group (34.3 vs 29.8 years). The cesarean section rate was higher (62.5% vs 33.3%) and the APGAR scores at the 1st and 5th minutes were lower in the cancer group. CONCLUSION: Management of pregnancies with papillary thyroid cancer treatment and follow-up requires a multidisciplinary approach with careful antenatal care and perinatal surveillance. Patients who have received papillary thyroid cancer treatment can safely undergo pregnancy. PMID- 29469034 TI - Early Successes in an Open Access, Provincially Funded Hepatitis C Treatment Program in Prince Edward Island. AB - INTRODUCTION: The availability of curative hepatitis C therapies has created an opportunity to improve treatment delivery and access. Local providers, government, industry, and community groups in Prince Edward Island developed an innovative province-wide care model. Our goal was to describe the first year of program implementation. MATERIAL AND METHODS: Using a communitybased prospective observational study design, all chronic hepatitis C referrals received from April 2015 to April 2016 were recorded in a database. Primary analysis assessed the time from referral to assessment/treatment, as well as the number of referrals, assessments, and treatment initiations. Secondary objectives included: (1) treatment effectiveness using intention-to-treat analysis; and (2) patient treatment experience assessed using demographics, adverse events, and medication adherence. RESULTS: During the study period 242 referrals were received, 123 patients were seen for intake assessments, and 93 initiated direct-acting antiviral therapy based on medical need. This is compared to 4 treatment initiations in the previous 2 years. The median time from assessment to treatment initiation was 3 weeks. Eighty-two of 84 (97.6%, 95% CI 91.7 - 99.7%) patients for whom outcome data were available achieved sustained virologic response at 12 weeks post-treatment; 1 was lost to follow-up and 1 died from an unrelated event. In the voluntary registry, 39.7% of patients reported missed treatment doses. CONCLUSION: In conclusion, results from the first 12 months of this multi-phase hepatitis C elimination strategy demonstrate improved access to treatment, and high rates of safe engagement and cure for patients living with chronic hepatitis C genotype 1 infections. PMID- 29469035 TI - Antifibrotic Mechanism of Pinocembrin: Impact on Oxidative Stress, Inflammation and TGF-beta /Smad Inhibition in Rats. AB - INTRODUCTION: The present study aimed to elucidate the potential antifibrotic effects of pinocembrin (PIN), a flavanone found abundantly in honey and propolis, by studying its effect on different oxidative stress, inflammatory and fibrosis markers in an experimental model of CCl4-induced liver fibrosis. MATERIAL AND METHODS: PIN (20 mg/kg) was given orally 3 times/week for 6 consecutive weeks alternating with CCl4 (0.5 mL/kg, 1:1 mixture with corn oil, i. p.) twice weekly. Different hepatotoxicity indices, oxidative stress, inflammatory and liver fibrosis markers were assessed. RESULTS: PIN significantly restored liver transaminases and total cholesterol to normal levels. Also, PIN ameliorated oxidative stress injury evoked by CCl4 as evidenced by inhibition of reduced glutathione depletion and lipid peroxidation as well as elevation of antioxidant enzyme superoxide dismutase (SOD). Further, PIN upregulated the nuclear factor erythroid 2 (NF-E2)-related factor 2 (Nrf2), thereby inducing the expression and activity of the cytoprotective enzyme hemeoxygenase-1 (HO-1). Moreover, PIN alleviated pro-inflammatory cytokines such as TNF-alpha via inhibiting nuclear factor-kappaB (NF-kappaB) activation. As markers of fibrosis, collagen and alpha SMA expression increased markedly in the CCl4 group and PIN prevented these alterations. In addition, PIN down-regulated TGFbeta1 and p-Smad2/3, thereby inhibiting TGFbeta1/Smad signaling pathway. CONCLUSION: These results suggest that PIN possess potent antifibrotic effects that can be explained on its antioxidant properties. It ameliorates oxidative stress and inflammation during induction of fibrogenesis via its ability to augment celular antioxidant defenses, activating Nrf2-mediated HO-1 expression and modulating NF-kappaB and TGF-beta1/Smad signaling pathway. PMID- 29469033 TI - Altered expression of the Cdk5 activator-like protein, Cdk5alpha, causes neurodegeneration, in part by accelerating the rate of aging. AB - Aging is the greatest risk factor for neurodegeneration, but the connection between the two processes remains opaque. This is in part for want of a rigorous way to define physiological age, as opposed to chronological age. Here, we develop a comprehensive metric for physiological age in Drosophila, based on genome-wide expression profiling. We applied this metric to a model of adult onset neurodegeneration, increased or decreased expression of the activating subunit of the Cdk5 protein kinase, encoded by the gene Cdk5alpha, the ortholog of mammalian p35. Cdk5alpha-mediated degeneration was associated with a 27-150% acceleration of the intrinsic rate of aging, depending on the tissue and genetic manipulation. Gene ontology analysis and direct experimental tests revealed that affected age-associated processes included numerous core phenotypes of neurodegeneration, including enhanced oxidative stress and impaired proteostasis. Taken together, our results suggest that Cdk5alpha-mediated neurodegeneration results from accelerated aging, in combination with cell-autonomous neuronal insults. These data fundamentally recast our picture of the relationship between neurodegeneration and its most prominent risk factor, natural aging. PMID- 29469036 TI - Incomplete Kawasaki Disease in an Infant with Cholangitis Post Kasai Surgery for Biliary Atresia. AB - Kawasaki's disease (KD) is a systemic vasculitis often seen with viral and bacterial infections. Cholangitis is a known complication in biliary atresia patients post Kasai Portoenterostomy (KP). However KD, in a biliary atresia patient post KP has not been previously reported. A 1 years old girl who had previously undergone a KP for BA, presented with cholangitis which was presumed to be caused by a previous enterobacter infection that she had 2 months ago. However, on treating the cholangitis, the patient developed fever again after ten days which persisted even after changing the antibiotics. By this time she also displayed three of five characteristic features of KD in form of fever, strawberry tongue and cervical adenopathy. Investigations showed high ESR, high CRP, thrombocythemia and dilated coronary vessels on echocardiography. Treatment with intravenous immunoglobulin (IVIG) and steroids caused the symptoms to subside. PMID- 29469037 TI - Hepatitis E Virus Genotype 1 Cases Imported to Portugal from India, 2016. AB - Hepatitis E in industrialized countries is mainly associated with genotype 3 hepatitis E virus (HEV) and normally causes a sporadic self-limiting disease in immunocompetent individuals. Unlike genotype 3, genotypes 1 and 2 circulate in developing countries, produce severe disease and occur in the epidemic form. Hepatitis E occurring in travellers returning from endemic areas in developing countries is not a novel epidemiological occurrence, however the vast majority of cases remain to be genetically studied. The present study describes two cases of severe acute hepatitis E that required hospitalization for 6 and 9 days in two individuals of Indian nationality that had recently migrated to Portugal to work. The retrieved HEV sequences both belonged to genotype 1 and had a high degree of nucleotide sequence identity, clustering with strains isolated in India and Nepal, in 2013 and 2014. Confirmed HEV genotypes of increased pathogenicity like genotype 1 are being introduced into otherwise naive populations of industrialized countries such as European countries with consequences difficult to predict. As far as we know the present study is the first in Portugal to describe and genetically characterize imported cases of hepatitis E infection caused by HEV genotype 1. PMID- 29469038 TI - Bacterial Translocation Is Linked to Increased Intestinal IFN-gamma, IL-4, IL-17, and mucin-2 in Cholestatic Rats. AB - : Background and rationale for the study. Bacterial translocation is an important triggering factor of infection and mortality in cirrhosis. In a rat model using bile duct ligation (BDL), bacterial translocation appears within 24 h after ligation. The dynamic between TH1/TH2/TH17 cytokines and the integrity of the colonic mucosa in the context of cirrhosis is little known. This study aims to determine the link between bacterial translocation and intestinal inflammation in a cholestasis model. Additionally, alterations of the colonic mucus layer and the bacterial load were also addressed. RESULTS: Bacterial translocation detected by microbiological cultures and MALDI-TOF showed that Escherichia coli predominates in mesenteric lymph nodes of BDL rats. Intestinal bacterial load analyzed by qPCR indicates a dramatic Escherichia/Shigella overgrowth at 8 and 30 days post-BDL. IFN-gamma, IL-4, and IL-17 evaluated by Western blotting were increased at 8 and 30 days in the small intestine. In the colon, in contrast, only IFN-gamma was significantly increased. The colonic mucus layer and mucin-2 expression determined by Alcian blue staining and immunohistochemistry surprisingly showed an increase in the mucus layer thickness related to increased mucin-2 expression during the entire process of liver damage. Hepatic enzymes, as well as collagen I, collagen III, TNF-alpha, and IL-6 liver gene expression were increased. In conclusion, bacterial overgrowth associated with bacterial translocation is linked to the over-expression of IFN-gamma, IL-4, IL-17 and mucin-2. These molecules might facilitate the intestinal permeability through exacerbating the inflammatory process and disturbing tight junctions, leading to the perpetuation of the liver damage.

PMID- 29469040 TI - Long-Term Follow-up and Quantitative Hepatitis B Surface Antigen Monitoring in North American Chronic HBV Carriers. AB - INTRODUCTION: Quantitative hepatitis B surface antigen (qHBsAg) combined with HBV DNA may be useful for predicting chronic hepatitis B (CHB) activity and nucleoside analogue (NA) response. MATERIAL AND METHODS: In this retrospective cohort study we evaluated qHBsAg levels according to CHB disease phase and among patients on treatment. Random effect logistic regression analysis was used to analyze qHBsAg change with time in the NA-treated cohort. RESULTS: 545 CHB carriers [56% M, median age 48 y (IQR 38-59), 73% Asian] had qHBsAg testing. In the untreated group (44%), 8% were classified as immune tolerant, 10% immune clearance, 40% inactive, and 43% had HBeAg- CHB and the median HBsAg levels were 4.6 (IQR 3.4-4.9), 4.0 (IQR 3.4-4.5), 2.9 (IQR 1.4-3.8), and 3.2 log IU/mL (IQR 2.6-4.0), respectively; p < 0.001. In the NA-treated group (28% entecavir, 68% tenofovir, 4% lamivudine), no significant change in qHBsAg levels occurred with time, 19% of patients on long-term NA had sustained qHBsAg < 2 log10 IU/mL. CONCLUSION: qHBsAg titers were associated with CHB phase and remained stable in those on long-term NA. A significant number of treated patients had low-level qHBsAg, of which some may be eligible for treatment discontinuation without risk of flare. PMID- 29469041 TI - Natural Extracts Abolished Lipid Accumulation in Cells Harbouring non-favourable PNPLA3 genotype. AB - : Background & aims. G-allele of PNPLA3 (rs738409) favours triglycerides accumulation and steatosis. In this study, we examined the effect of quercetin and natural extracts from mushroom and artichoke on reducing lipid accumulation in hepatic cells. MATERIAL AND METHODS: Huh7.5 cells were exposed to oleic acid (OA) and treated with quercetin and extracts to observe the lipid accumulation, the intracellular-TG concentration and the LD size. Sterol regulatory element binding proteins-1 (SREBP-1), peroxisome proliferator-activated receptor (PPARalpha-gamma) and cholesterol acyltransferase (ACAT) gene expression levels were analysed. RESULTS: Quercetin decreased the intracellular lipids, LD size and the levels of intracellular-TG through the down-regulation of SREBP-1c, PPARgamma and ACAT1 increasing PPARalpha. The natural-extracts suppressed OA-induced lipid accumulation and the intracellular-TG. They down-regulate the hepatic lipogenesis through SREBP-1c, besides the activation of lipolysis through the increasing of PPARalpha expression. CONCLUSIONS: Quercetin and the aqueous extracts decrease intracellular lipid accumulation by down-regulation of lipogenesis and up regulation of lipolysis. PMID- 29469042 TI - More Evidence for the Genetic Susceptibility of Mexican Population to Nonalcoholic Fatty Liver Disease through PNPLA3. AB - BACKGROUND: The gene for patatin-like phospholipase domain containing 3 (PNPLA3) is associated with nonalcoholic fatty liver disease (NAFLD) development. We previously found that Mexican indigenous population had the highest frequency reported of the PNPLA3 148M risk allele. Further, we observed a relationship between M148M genotype with elevated ALT levels in individuals with normal weight, overweight and obese. We sought to investigate whether PNPLA3 polymorphism is associated with NAFLD development in Mexicans. MATERIAL AND METHODS: We enrolled 189 Mexican patients with NAFLD and 201 healthy controls. Anthropometric, metabolic, and biochemical variables were measured, and rs738409 (Ile148Met substitution) polymorphism was genotyped by sequencing. RESULTS: Logistic regression analysis, using a recessive model, suggested that PNPLA3 polymorphism in Mexican population is significantly associated (OR = 1.711, 95% CI: 1.014-2.886; P = 0.044) with NAFLD. CONCLUSIONS: The PNPLA3 gene is associated with NAFLD in Mexican population. More studies are required to explain the high prevalence of PNPLA3 polymorphism in Mexican-Americans, Mexican-Indians, and Mexican-Mestizos. PMID- 29469043 TI - Viscoelastic Testing in Liver Disease. AB - Long thought to be hypocoagulable, new evidence suggests cirrhosis patients have "rebalanced" coagulation in the setting of decreased synthesis of both pro- and anti-coagulant factors. Traditional testing like PT/INR reflects only the decreased synthesis of pro-coagulant factors and thus does not correspond to bleeding or clotting risk in this population. In this review, we discuss the use of viscoelastic testing (VET), an assay of global hemostasis in cirrhosis patients. We describe the technique and interpretation of commercially available VET and assess the application of VET in both transplant and non-transplant cirrhosis populations. VET largely correlates well with traditional testing including platelet count and fibrinogen level, however, is potentially less accurate in patients with low fibrinogen levels. VET may be useful in identifying patients at higher risk of hypercoagulable complications post-transplant and reflects changes in hemostasis in decompensated patients. While VET has been associated with decreased transfusion support in multiple studies, the lack of bleeding in patients who avoided prophylactic transfusion suggests a "rescue" rather than prophylactic approach to transfusion may be ideal and further studies with a "rescue" arm are needed. Additional prospective studies of VET should include clinically relevant endpoints of bleeding and thrombosis. PMID- 29469044 TI - TCR Vbeta Usage of Peripheral Blood and Liver Infiltrating Lymphocytes in Patients with Chronic Hepatitis B. AB - INTRODUCTION: Chronic hepatitis B (CHB) is still a public health problem and its mechanism remains unclear. In this study, we detect the skewness of T cell receptor beta chain variable gene (TCR Vbeta) in peripheral blood lymphocytes (PBL) and the liver infiltrating lymphocytes (LIL) of patients with CHB; and hope to provide information for further research on the pathogenic mechanism of CHB. MATERIAL AND METHODS: Fifteen patients with CHB, ten healthy volunteers and three patients with liver cysts were recruited as the subjects. The usage of TCR Vbeta of PBL and LIL were measured and compared; the associations of the TCR Vbeta usage of PBL with some hematological indices, including human leukocyte antigen (HLA) alleles, percents of CD4+ and CD8+ T cells, sera levels of HBV-DNA and IFN gamma, were analyzed. RESULTS: In PBL, Vbeta12 and Vbeta13.1 were the highest predominant usage genes which usage frequencies were all 46.7%; Vbeta23 was the key limited usage gene (40.0%). In LIL, the mainly predominant and limited usage gene was Vbeta13.1 (73.3%) and Vbeta23 (46.7%), respectively. About half of the patients with CHB with HLA-DR9 or HLA-DR12 showed the predominant usage of Vbeta5.2 or Vbeta13.2. In patients with CHB, the percentage of CD4+ T cells was 33.41 +/- 5.39 %, that of CD8+ T cells was 28.67 +/- 6.77 %; the concentration of IFN-gamma was 182.52 +/- 44.16 pg/mL. Compared to the healthy controls, there were significant differences for these data (P < 0.05). Neither ALT nor HBV-DNA was relative to the usage of TCR Vbeta. CONCLUSIONS: PBL and LIL share the common sknewness of TCR Vbeta genes, which probably relates to some hematological indices. However, the roles of such similarities and associations in the development of CHB need further study. PMID- 29469045 TI - Clinical Significance of Serum Adiponectin and Resistin Levels in Liver Cirrhosis. AB - INTRODUCTION: Adiponectin and resistin levels are increased in patients with cirrhosis, but it prognostic significance is unknown. We sought to investigate the factors associated with adiponectin and resistin levels and its clinical significance in patients with cirrhosis. MATERIALS AND METHODS: This was a prospective cohort study that included 122 subjects with cirrhosis who attended an outpatient clinic and were initially evaluated in 2012. Serum adiponectin and resistin levels were measured in samples collected in 2012 (adiponectin and resistin) and 2014 (adiponectin). Thirty healthy subjects served as a control group. RESULTS: Higher adiponectin (21.59 MU g/mL vs. 12.52 MUg/mL, P < 0.001) and resistin levels (3.83 ng/mL vs. 2.66 ng/mL, P < 0.001) were observed among patients with cirrhosis compared to controls. Patients classified as Child-Pugh B/C had higher adiponectin levels in relation to Child-Pugh A patients. At second measurement, adiponectin levels increased significantly in non-transplant patients and decreased in liver transplant recipients. Univariate Cox analysis showed that among patients with alcoholic liver disease, adiponectin levels were associated with lower transplant-free survival (HR = 1.034, 95% CI 1.006 - 1.062, P = 0.016). The transplant-free survival was significantly lower among patients with alcoholic liver disease and adiponectin >= 17 MUg/mL (26.55 months, 95% CI 21.40-31.70) as compared to those with levels < 17 MUg/mL (33.76 months, 95% CI 30.70-36.82) (P = 0.045). No relationship was found between the levels of resistin and survival. CONCLUSION: Adiponectin but not resistin levels were associated with intensity of liver dysfunction and worse prognosis in patients with alcoholic liver disease, suggesting a potential as a prognostic biomarker. PMID- 29469046 TI - Treatment of Type-1 Hepatorenal Syndrome with Pentoxifylline: A Randomized Placebo Controlled Clinical Trial. AB - INTRODUCTION: Type-1 hepatorenal syndrome (HRS-1) portends a poor prognosis in patients with cirrhosis. Currently available medical therapies are largely ineffective, save for liver transplantation. We aimed to determine if pentoxifylline (PTX) therapy in addition to the standard of care of volume expansion with albumin and vasoconstriction with midodrine and octreotide (AMO) is safe and efficacious compared to AMO in HRS-1 treatment. MATERIAL AND METHODS: Hospitalized subjects with decompensated cirrhosis and HRS-1 were enrolled. PTX or placebo was administered with AMO therapy for up to 14 days. The primary endpoint was HRS-1 resolution (serum creatinine <= 1.5 g/dL for > 24 h). Secondary endpoints were change in creatinine and MELD score, partial treatment response, 30-and 180-day overall and transplant free survival. RESULTS: Twelve subjects with mean age 58.9 +/- 6.2 years were enrolled and randomized. Mean MELD score was 26.5 +/- 7.4 and 58.3% were male. Overall cohort 30- and 180-day survival was 58.3% and 33.3% respectively. Two subjects underwent liver transplantation. HRS-1 resolution (16.7% vs. 16.7%, p = 1.000), partial treatment response (33.3% vs. 16.7%, p = 0.505), change in creatinine (+0.48 g/dL, 95% CI 0.49-1.46 vs. +0.03 g/dL, 95% CI -0.64- 0.70, p = 0.427), 30-day survival (66.6% vs. 50.0%, p = 0.558) and 180-day survival (50.0% vs. 16.7%, p = 0.221) were similar between the two groups. Serious adverse events necessitating treatment discontinuation were rare (n = 1, PTX). DISCUSSION: The addition of PTX to AMO in the treatment of HRS-1 is safe when compared to the current standard of care. Future large-scale prospective study to validate the efficacy of this treatment seems warranted. PMID- 29469047 TI - Racial, Ethnic, and Age Disparities in Incidence and Survival of Intrahepatic Cholangiocarcinoma in the United States; 1995-2014. AB - INTRODUCTION: Despite reports of increased incidence of intrahepatic cholangiocarcinoma (iCCA) in the United States, the impact of age or influences of race and ethnicity are not clear. Disparities in iCCA outcomes across various population subgroups also are not readily recognized due to the rarity of this cancer. We examined ethnic, race, age, and gender variations in iCCA incidence and survival using data from the Surveillance, Epidemiology, and End Results Program (1995-2014). MATERIALS AND METHODS: We assessed age-adjusted incidence rates, average annual percentage change in incidence, and hazard ratios (HRs) with 95% confidence intervals (CIs) for all-cause and iCCA-specific mortality. RESULTS: Overall, 11,127 cases of iCCA were identified, with an age-adjusted incidence rate of 0.92 per 100,000. The incidence rate increased twofold, from 0.49 per 100,000 in 1995 to 1.49 per 100,000 in 2014, with an average annual rate of increase of 5.49%. The iCCA incidence rate was higher among persons age 45 years or older than those younger than 45 years (1.71 vs. 0.07 per 100,000), among males than females (0.97 vs. 0.88 per 100,000) and among Hispanics than non Hispanics (1.18 vs. 0.89 per 100,000). Compared to non-Hispanics, Hispanics had poorer 5-year all-cause mortality (HR=1.11, 95%CI: 1.05-1.19) and poorer iCCA specific mortality (HR=1.15, 95%CI: 1.07-1.24). Survival rates were poor also for individuals age 45 years or older, men, Blacks, and American Indians/Alaska Natives. CONCLUSION: The results demonstrate ethnic, race, age and gender disparities in iCCA incidence and survival, and confirm continued increase in iCCA incidence in the United States. PMID- 29469048 TI - Results of Liver Transplantation for Hepatocellular Carcinoma in a Multicenter Latin American Cohort Study. AB - BACKGROUND AND AIMS: Heterogeneous data has been reported regarding liver transplantation (LT) for hepatocellular carcinoma (HCC) in Latin America. We aimed to describe treatment during waiting list, survival and recurrence of HCC after LT in a multicenter study from Latin America. MATERIAL AND METHODS: Patients with HCC diagnosed prior to transplant (cHCC) and incidentally found in the explanted liver (iHCC) were included. Imaging-explanted features were compared in cHCC (non-discordant if pre and post-LT were within Milan, discordant if pre-LT was within and post-LT exceeding Milan). RESULTS: Overall, 435 patients with cHCC and 92 with iHCC were included. At listing, 81% and 91% of cHCC patients were within Milan and San Francisco criteria (UCSF), respectively. Five year survival and recurrence rates for cHCC within Milan, exceeding Milan/within UCSF and beyond UCSF were 71% and 16%; 66% and 26%; 46% and 55%, respectively. Locoregional treatment prior to LT was performed in 39% of cHCC within Milan, in 53% beyond Milan/within UCSF and in 83% exceeding UCSF (p < 0.0001). This treatment difference was not observed according to AFP values (<=100, 44%; 101 1,000, 39%, and > 1,000 ng/mL 64%; p = 0.12). Discordant imaging-explanted data was observed in 29% of cHCC, showing lower survival HR 2.02 (CI 1.29; 3.15) and higher recurrence rates HR 2.34 when compared to AFP <100 ng/mL. Serum AFP > 1,000 ng/mL at listing was independently associated with a higher 5-year recurrence rate and a HR of 3.24 when compared to AFP <100 ng/mL. CONCLUSION: Although overall results are comparable to other regions worldwide, pre-LT treatment not only considering imaging data but also AFP values should be contemplated during the next years. PMID- 29469049 TI - Safety and Efficacy of Laparoscopic Radiofrequency Ablation for Hepatic Hemangiomas: A Multicenter Retrospective Study. AB - INTRODUCTION: Radiofrequency ablation (RFA) is an effective and minimally invasive technique for the management of hepatic hemangiomas (HHs). This study aims to assess the safety and efficacy of laparoscopic RFA for HHs. MATERIAL AND METHODS: Forty-four patients with 50 hepatic hemangiomas (5-10 cm in diameter) undergoing laparoscopic RFA from January 2012 to May 2015 at three tertiary hospitals in China were retrospectively analyzed. RESULTS: Thirty-three patients with subcapsular hemangiomas were treated with a laparoscopic approach, and 11 patients with lesions in the liver parenchyma were treated with a combined laparoscopy and an ultrasound-guided percutaneous approach. No conversion to open surgery or two-step surgery occurred during the study period. Patients with small hemangiomas (< 7 cm) required a significantly shorter operating time (71.1 +/- 20.18 min vs. 106 +/- 23.55 min, p = 0.000) and fewer punctures compared with patients with large hemangiomas (> 7 cm) (4.61 +/- 1.09 vs. 6.73 +/-1.01, P < 0.05). According to the Dindo-Clavien classification, 15 patients experienced 34 Grade 1 complications, and two had complications of Grade 3a. All complications were resolved by conservative treatment. Forty-three (86.0%) HHs in 38 patients were completely ablated after RFA, and 7 (14.0%) HHs in 6 patients were incompletely ablated. All patients were followed up for 6-24 months (mean 15 +/- 6 months). CONCLUSION: The data showed that laparoscopic RFA is an effective treatment for small (< 10 cm) HHs. While the incidence of postoperative complications remains high, the majority of complications are minor. Patients undergoing laparoscopic RFA for HHs, even for the small ones, should be carefully selected. PMID- 29469050 TI - Natural Extracts as Modifiers of Intracellular Lipid Handling. PMID- 29469051 TI - Nonalcoholic Fatty Liver Disease Progresses into Severe NASH when Physiological Mechanisms of Tissue Homeostasis Collapse. AB - Phenotypic modulation of NAFLD-severity by molecules derived from white (adipokines) and brown (batokines) adipose tissue may be important in inducing or protecting against the progression of the disease. Adipose tissue-derived factors can promote the progression of NAFLD towards severe histological stages (NASH fibrosis and NASHcirrhosis). This effect can be modulated by the release of adipokines or batokines that directly trigger an inflammatory response in the liver tissue or indirectly modulate related phenotypes, such as insulin resistance. Metabolically dysfunctional adipose tissue, which is often infiltrated by macrophages and crown-like histological structures, may also show impaired production of anti-inflammatory cytokines, which may favor NAFLD progression into aggressive phenotypes by preventing its protective effects on the liver tissue. PMID- 29469052 TI - Recent Advances in Hepatotoxicity of Non Steroidal Anti-Inflammatory Drugs. AB - Non-steroidal-anti-inflammatory drugs (NSAIDs) make a heterogenous pharmaco therapeutic class of drugs among the most used drugs worldwide with various indications, modes of administration and increasing automedication. NSAIDs can cause acute liver injury with variable severity. The recent identification of genetic markers might facilitate the diagnosis and the prediction of hepatotoxicity risk. PMID- 29469053 TI - Fontan-Associated Liver Disease: A Review. AB - Fontan-associated liver disease is a hepatic disorder arising from hemodynamic changes and systemic venous congestion following Fontan surgery. The histological changes produced in the liver are similar but not equivalent to those seen in other forms of cardiac liver disease. While the natural history of this form of liver disease is not well established, over time many Fontan patients develop portal hypertension-related complications such as ascites, variceal hemorrhage or encephalopathy. Fontan survivors also show an increased risk of hepatocellular carcinoma. Early diagnosis of advanced liver disease is mandatory for the prevention and treatment of complications such as hepatocellular carcinoma, esophageal varices and malnutrition. This review updates current knowledge of the pathophysiology and management of Fontan-associated liver disease including new diagnostic methods and treatments. PMID- 29469054 TI - Significance of the impact of motion compensation on the variability of PET image features. AB - In lung cancer, quantification by positron emission tomography/computed tomography (PET/CT) imaging presents challenges due to respiratory movement. Our primary aim was to study the impact of motion compensation implied by retrospectively gated (4D)-PET/CT on the variability of PET quantitative parameters. Its significance was evaluated by comparison with the variability due to (i) the voxel size in image reconstruction and (ii) the voxel size in image post-resampling. The method employed for feature extraction was chosen based on the analysis of (i) the effect of discretization of the standardized uptake value (SUV) on complementarity between texture features (TF) and conventional indices, (ii) the impact of the segmentation method on the variability of image features, and (iii) the variability of image features across the time-frame of 4D-PET. Thirty-one PET-features were involved. Three SUV discretization methods were applied: a constant width (SUV resolution) of the resampling bin (method RW), a constant number of bins (method RN) and RN on the image obtained after histogram equalization (method EqRN). The segmentation approaches evaluated were 40[Formula: see text] of SUVmax and the contrast oriented algorithm (COA). Parameters derived from 4D-PET images were compared with values derived from the PET image obtained for (i) the static protocol used in our clinical routine (3D) and (ii) the 3D image post-resampled to the voxel size of the 4D image and PET image derived after modifying the reconstruction of the 3D image to comprise the voxel size of the 4D image. Results showed that TF complementarity with conventional indices was sensitive to the SUV discretization method. In the comparison of COA and 40[Formula: see text] contours, despite the values not being interchangeable, all image features showed strong linear correlations (r > 0.91, [Formula: see text]). Across the time-frames of 4D-PET, all image features followed a normal distribution in most patients. For our patient cohort, the compensation of tumor motion did not have a significant impact on the quantitative PET parameters. The variability of PET parameters due to voxel size in image reconstruction was more significant than variability due to voxel size in image post-resampling. In conclusion, most of the parameters (apart from the contrast of neighborhood matrix) were robust to the motion compensation implied by 4D-PET/CT. The impact on parameter variability due to the voxel size in image reconstruction and in image post-resampling could not be assumed to be equivalent. PMID- 29469055 TI - A head motion estimation algorithm for motion artifact correction in dental CT imaging. AB - A small head motion of the patient can compromise the image quality in a dental CT, in which a slow cone-beam scan is adopted. We introduce a retrospective head motion estimation method by which we can estimate the motion waveform from the projection images without employing any external motion monitoring devices. We compute the cross-correlation between every two successive projection images, which results in a sinusoid-like displacement curve over the projection view when there is no patient motion. However, the displacement curve deviates from the sinusoid-like form when patient motion occurs. We develop a method to estimate the motion waveform with a single parameter derived from the displacement curve with aid of image entropy minimization. To verify the motion estimation method, we use a lab-built micro-CT that can emulate major head motions during dental CT scans, such as tilting and nodding, in a controlled way. We find that the estimated motion waveform conforms well to the actual motion waveform. To further verify the motion estimation method, we correct the motion artifacts with the estimated motion waveform. After motion artifact correction, the corrected images look almost identical to the reference images, with structural similarity index values greater than 0.81 in the phantom and rat imaging studies. PMID- 29469056 TI - Stress induced magnetic-domain evolution in magnetoelectric composites. AB - Local observation of the stress mediated magnetoelectric (ME) effect in composites has gained a great deal of interest over the last decades. However, there is an apparent lack of rigorous methods for a quantitative characterization of the ME effect at the local scale, especially in polycrystalline microstructures. In the present work, we address this issue by locally probing the surface magnetic state of barium titante-hexagonal barium ferrite (BaTiO3 BaFe12O19) ceramic composites using magnetic force microscopy (MFM). The effect of the piezoelectrically induced local stress on the magnetostrictive component (BaFe12O19, BaM) was observed in the form of the evolution of the magnetic domains. The local piezoelectric stress was induced by applying a voltage to the neighboring BaTiO3 grains, using a conductive atomic force microscopy tip. The resulting stochastic evolution of magnetic domains was studied in the context of the induced magnetoelastic anisotropy. In order to overcome the ambiguity in the domain changes observed by MFM, certain generalizations about the observed MFM contrast are put forward, followed by application of an algorithm for extracting the average micromagnetic changes. An average change in domain wall thickness of 50 nm was extracted, giving a lower limit on the corresponding induced magnetoelastic anisotropy energy. Furthermore, we demonstrate that this induced magnetomechanical energy is approximately equal to the K1 magnetocrystalline anisotropy constant of BaM, and compare it with a modeled value of applied elastic energy density. The comparison allowed us to judge the quality of the interfaces in the composite system, by roughly gauging the energy conversion ratio. PMID- 29469057 TI - Localized surface plasmon enhanced deep UV-emitting of AlGaN based multi-quantum wells by Al nanoparticles on SiO2 dielectric interlayer. AB - In this paper, we report a 2.6-fold deep ultraviolet emission enhancement of integrated photoluminescence (PL) intensity in AlGaN-based multi-quantum wells (MQWs) by introducing the coupling of local surface plasmons from Al nanoparticles (NPs) on a SiO2 dielectric interlayer with excitons and photons in MQWs at room temperature. In comparison to bare AlGaN MQWs, a significant 2.3 fold enhancement of the internal quantum efficiency, from 16% to 37%, as well as a 13% enhancement of photon extraction efficiency have been observed in the MQWs decorated with Al NPs on SiO2 dielectric interlayer. Polarization-dependent PL measurement showed that both the transverse electric and transverse magnetic mode were stronger than the original intensity in bare AlGaN MQWs, indicating a strong LSPs coupling process and vigorous scattering ability of the Al/SiO2 composite structure. These results were confirmed by the activation energy of non-radiative recombination from temperature-dependent PL measurement and the theoretical three dimensional finite difference time domain calculations. PMID- 29469058 TI - Straightforward measurement of anisotropic thermal properties of a Bi2Se3 single crystal. AB - We demonstrate here a simple measurement protocol which allows the thermal properties of anisotropic crystalline materials to be determined. This protocol is validated by the measurement of Bi2Se3, a layered material consisting of covalently bonded sheets with weak van der Waals bonds between each layer, which has highly anisotropic thermal properties. Thermoreflectance microscopy measurements were carried out on a single-crystal Bi2Se3 sample, firstly on the bare sample and then after capping with a 100 nm thick gold layer. Whereas on the bare sample lateral heat diffusion is dominated by the in-plane thermal diffusivity, on the metal-capped substrate heat diffusion perpendicular to the sample surface dominates. Using a simple theoretical model, we show how this double measurement protocol allows the anisotropic thermal conductivity coefficients of bulk Bi2Se3 to be evaluated. PMID- 29469059 TI - Low-friction nanojoint prototype. AB - High surface energy of individual nanostructures leads to high adhesion and static friction that can completely hinder the operation of nanoscale systems with movable parts. For instance, silver or gold nanowires cannot be moved on silicon substrate without plastic deformation. In this paper, we experimentally demonstrate an operational prototype of a low-friction nanojoint. The movable part of the prototype is made either from a gold or silver nano-pin produced by laser-induced partial melting of silver and gold nanowires resulting in the formation of rounded bulbs on their ends. The nano-pin is then manipulated into the inverted pyramid (i-pyramids) specially etched in a Si wafer. Due to the small contact area, the nano-pin can be repeatedly tilted inside an i-pyramid as a rigid object without noticeable deformation. At the same time in the absence of external force the nanojoint is stable and preserves its position and tilt angle. Experiments are performed inside a scanning electron microscope and are supported by finite element method simulations. PMID- 29469060 TI - Single-fabrication-step Ge nanosphere/SiO2/SiGe heterostructures: a key enabler for realizing Ge MOS devices. AB - We report channel and strain engineering of self-organized, gate-stacking heterostructures comprising Ge-nanosphere gate/SiO2/SiGe-channels. An exquisitely controlled dynamic balance between the concentrations of oxygen, Si, and Ge interstitials was effectively exploited to simultaneously create these heterostructures in a single oxidation step. Process-controlled tunability of the channel length (5-95 nm diameters for the Ge-nanospheres), gate oxide thickness (2.5-4.8 nm), as well as crystal orientation, chemical composition and strain engineering of the SiGe-channel was achieved. Single-crystalline (100) Si1-x Ge x shells with Ge content as high as x = 0.85 and with a compressive strain of 3%, as well as (110) Si1-x Ge x shells with Ge content of x = 0.35 and corresponding compressive strain of 1.5% were achieved. For each crystal orientation, our high Ge-content, highly-stressed SiGe shells feature a high degree of crystallinity and thus, provide a core 'building block' required for the fabrication of Ge based MOS devices. PMID- 29469061 TI - A self-resetting spiking phase-change neuron. AB - Neuromorphic, or brain-inspired, computing applications of phase-change devices have to date concentrated primarily on the implementation of phase-change synapses. However, the so-called accumulation mode of operation inherent in phase change materials and devices can also be used to mimic the integrative properties of a biological neuron. Here we demonstrate, using physical modelling of nanoscale devices and SPICE modelling of associated circuits, that a single phase change memory cell integrated into a comparator type circuit can deliver a basic hardware mimic of an integrate-and-fire spiking neuron with self-resetting capabilities. Such phase-change neurons, in combination with phase-change synapses, can potentially open a new route for the realisation of all-phase change neuromorphic computing. PMID- 29469062 TI - Fine structure of metal-insulator transition in EuO resolved by doping engineering. AB - Metal-insulator transitions (MITs) offer new functionalities for nanoelectronics. However, ongoing attempts to control the resistivity by external stimuli are hindered by strong coupling of spin, charge, orbital and lattice degrees of freedom. This difficulty presents a quest for materials which exhibit MIT caused by a single degree of freedom. In the archetypal ferromagnetic semiconductor EuO, magnetic orders dominate the MIT. Here we report a new approach to take doping under control in this material on the nanoscale: formation of oxygen vacancies is strongly suppressed to exhibit the highest MIT resistivity jump and magnetoresistance among thin films. The nature of the MIT is revealed in Gd doped films. The critical doping is determined to be more than an order of magnitude lower than in all previous studies. In lightly doped films, a remarkable thermal hysteresis in resistivity is discovered. It extends over 100 K in the paramagnetic phase reaching 3 orders of magnitude. In the warming mode, the MIT is shown to be a two-step process. The resistivity patterns are consistent with an active role of magnetic polarons-formation of a narrow band and its thermal destruction. High-temperature magnetic polaron effects include large negative magnetoresistance and ferromagnetic droplets revealed by x-ray magnetic circular dichroism. Our findings have wide-range implications for the understanding of strongly correlated oxides and establish fundamental benchmarks to guide theoretical models of the MIT. PMID- 29469063 TI - A study of serum vascular endothelial growth factor in infantile hemangiomas. AB - Background: Though infantile hemangiomas are the most common benign tumor of infancy, their etiopathogenesis is not fully understood. Some studies report a diagnostic role for vascular endothelial growth factor (VEGF), but such studies are lacking from India. Aims: To study the clinicoepidemiological profile of infantile hemangiomas, to estimate and compare the serum levels of VEGF in infantile hemangiomas and controls, and to determine correlations between serum levels of VEGF and growth characteristics of infantile hemangiomas. Methods: A hospital-based, cross-sectional study was carried out on 30 clinically diagnosed cases of infantile hemangioma and 30 controls presenting with other disorders. VEGF levels were recorded for both cases and controls by the sandwich enzyme linked immunosorbent assay (ELISA) technique. Results were analyzed using SPSS version 20.0, and their significance determined using appropriate tests. Results: Mean serum VEGF level in the cases was 216.8 +/- 49.2 pg/ml while in the control group it was 115.1 +/- 43.1 pg/ml (P < 0.0001). There were no statistically significant correlations between serum VEGF levels and sex or size, phase of growth, morphological variants or ulceration of lesions. Limitations: Our sample was not large enough to draw clinically applicable conclusions. An adequate sample size could not be achieved because of low incidence of the disease, and resource and time constraints. Conclusions: The mean value of serum VEGF in the study group was significantly higher than that in the control group, suggesting that serum VEGF can serve as a diagnostic marker of infantile hemangiomas. Mean serum VEGF was higher in proliferative lesions than in involuting lesions, indicating that it may also be useful as a prognostic serological marker in cases of infantile hemangioma.

PMID- 29469066 TI - Clinico-pathological profile of colorectal cancer in first two decades of life: A retrospective analysis from tertiary health center. AB - AIM: This retrospective observational study was done to analyze age, gender, site of primary tumor and histological characterstics in patients of colorectal carcinoma in the first two decades of life. MATERIAL AND METHOD: A total of 373 patients of colorectal patients were registered in the Department of Radiation Oncology from January 2010 to December 2015. Patients who were <20 years of age were analyzed for clinicopathological characteristic. RESULTS: In our study, a total of 29 out of 373 patients (7.75%) were <=20 years. Male to female distribution was 2.2:1. Younger age group presented with advanced Stage III and IV 58.62% and 10.34% patients, respectively. Only 9 (30.5%) patients were of Stage I and II. The most common involved site was rectum in 21 (72.41%) patients, followed by rectosigmoid involvement in 5 (17.24%). CONCLUSIONS: Colorectal carcinoma in young adults is usually locally advanced or metastatic. Therefore, the diagnosis of CRC should be done at early and curable stage. Bleeding per rectum in a younger age group should not be ignored but must be properly evaluated. PMID- 29469067 TI - Histopathologic review of 400 biopsies and resection specimens of trunk and extremity-based soft tissue tumors. AB - AIMS: To review various pathologic parameters in diagnosed cases of trunk and extremity-based soft tissue tumors (STTs), in order to identify concordance rate between initial biopsy and resection specimen and discrepancies between initial and review diagnosis, by a specialist pathologist. MATERIALS AND METHODS: Over a 2-year-period, 400 retrospectively diagnosed STTs (553 specimens) including referral and "in-house" cases were studied. The reviewing specialist pathologist was blinded to the initial diagnoses. Discordances including discrepancies and deficiencies were defined as major and minor. Major discrepancies included those that could lead to significant treatment changes. True discrepancies were those related to sampling issues between the biopsies and resection specimens. Deficiencies relating to tumor subtyping, sarcoma grading, documentation of tumor size, and marginal status (in resections) were subdivided as major and minor. RESULTS: Most cases (328, 82%) were sarcomas (most common, synovial sarcoma; most common Stage, III), followed by benign tumors (36, 9%) (most common, schwannoma) and intermediate malignancies (32, 8%) (most common, fibromatosis). Within STTs, liposarcomas, neural tumors, and undifferentiated pleomorphic sarcomas were relatively more frequently associated with discrepancies. Percentage of cases with major discordances between the referral reports (100 cases) and review diagnosis was 60%. Percentage of cases with major discordances between the specialist and other oncopathologists was 11%. True discrepancies were observed in 20 (5%) cases. The association of type of specimen with the rate of discordance was not significant (P = 0.114). CONCLUSIONS: Diagnoses of STTs are fraught with errors mostly from general pathologists, followed by nonspecialist oncopathologists. These findings reinforce the need for reporting of STTs, especially sarcomas, by specialist pathologists. PMID- 29469068 TI - Reirradiation for recurrent primary central nervous system tumors: Eight-year audit from a tertiary cancer care center in South India. AB - BACKGROUND: Radiation therapy is a major treatment option in the management of primary central nervous system (CNS) tumors, though recurrences after primary treatment, especially in high-grade glial tumors, is a challenge for treating physician. Advances in the field of radiation have made reirradiation a feasible option in recurrent CNS tumors. MATERIALS AND METHODS: Details of patients with primary CNS lesions who presented between 2009 and 2016, with recurrent CNS lesions, and who were treated with reirradiation were retrieved from electronic medical records, as a departmental audit, and the outcome was analyzed. RESULTS: A total of 33 patients received reirradiation. Median follow-up was 112.7 months. Median age at presentation was 36 years. On completing initial treatment, 42.4% had no residual disease. Median time to symptomatic recurrence was 51.33 months. For reirradiation, stereotactic radiotherapy was used in 27.3%, stereotactic radiosurgery in 12.1%, and intensity-modulated radiation therapy in 36.4%. Mean cumulative 2 Gy equivalent dose (EQD2) was 111.00 +/- 15.287 Gy. At the last follow-up, 57.6% of patients were alive, and 27.3% had succumbed to the disease. Median OS was 187.67 months. Three-year survival after reirradiation was 74.1%. CONCLUSION: Our study is probably one of the first from the Indian subcontinent analyzing a series of reirradiation in primary CNS tumors. Our survival subsequent to reirradiation is comparable to that in available literature; which are also mostly retrospective. Our analysis also substantiates that younger patients, longer intervals between the two sets of radiation and biologically effective dose <100 Gy and EQD2Cumulativeof <100 Gy are factors that favorably improve the survival after reirradiation as has been shown in literature. PMID- 29469069 TI - Retrospective analysis of patients with relapsed or refractory testicular nonseminous germ cell tumors treated with autologous stem cell transplantation. AB - BACKGROUND AND AIM: About 20-25% of the testicular germ cell tumors (TGCT) are relapsed or refractory after first line therapy and optimal treatment for this group is poorly defined. We aimed to analyze the efficacy and safety of autologous stem cell transplantation (ASCT) in this patient group.Material and. METHODS: 19 patients with 28 ASCT were retrospectively analyzed. All the patients were treated with BEP (Bleomycin, etoposide, cisplatin) as first line therapy and TIP(paclitexalifosfamide, cisplatin) was given as salvage chemotherapy. Stem cell collection was performed with TIP and granulocyte stimulating factor. ASCT was performed with carboplatin(700mg/m2) and etoposite(750mg /m 2). The results were provided as median(min-max). P<0.05 was accepted as statistical significant level. RESULTS: After ASCT, complete(CR) and partial remission (PR) rates were 47.3% and 31 .5% respectively. The median overall survival(OS) and progression free survival (PFS) were 18(0-37.4 months) and 7(0-15months) months respectively. Estimated 2-year OS was 47.4% and PFS was 35.3%. Grade 3/4 toxicities including diarrhea, mucositis, and toxic hepatitis were observed in 5 patients. Only one patient died due to complication of transplantation. CONCLUSION: Although the number of the patients in this study is limited, ASCT seems to be a safe and effective treatment modality in relapsed refractory non-seminomatousTGCT with an acceptable OS, PFS and mortality rates. PMID- 29469070 TI - Utilization of pelvic lymph node dissection in patients undergoing robot-assisted radical prostatectomy in India versus the United States - A Vattikuti Collective Quality Initiative database analysis. AB - BACKGROUND: The utilization and extent of pelvic lymph node dissection (PLND) varies depending on the disease and practice patterns. AIMS: This study compares practice patterns in utilization of PLND between Indian and United States (US) practices. SETTINGS AND DESIGN: We focused on 415 patients (204 India; 211 US) prostate cancer patients treated with robot-assisted radical prostatectomy, between 2015 and 2016, within the Vattikuti Collective Quality Initiative database. SUBJECTS AND METHODS: Utilization of PLND and number of nodes removed were evaluated for the entire cohort, and after stratifying for Country of treatment and D'Amico risk groups. Logistic regression tested the relationship between PLND and country of treatment, after adjusting for disease risk. RESULTS: Indian patients had a higher risk distribution (D'Amico high-risk 53.4% in India vs. 27% in the US; P< 0.001) compared to their US counterparts. Overall, 193/204 (94.6%) Indian patients underwent PLND versus 181/211 (85.8%) US patients (P = 0.003). When stratified based on disease risk, PLND was performed more frequently in Indian patients with low-risk disease (81.0% vs. 41.4%,P= 0.008), but not in those with intermediate and high-risk disease. On multivariable analysis, Indian patients had a 2.57-fold higher probability of undergoing PLND than their US counterparts (P = 0.02). The analysis of the number of lymph nodes removed showed similar trends. CONCLUSIONS: Indian patients are more likely to undergo PLND than US patients. This is, especially true for patients with low-risk disease, who are unlikely to benefit from this procedure. Efforts should focus on optimizing the utilization of PLND, and deliver it only when there is clinical indication.

Microsatellites are short tandem repeat sequences, present over the span of human genome and are known to be variable at multiple loci due to errors in DNA Mismatch Repair machinery. AIM: The present study was aimed to evaluate the association between Microsatellite Instability (MSI) and evolution of Chronic Myeloid Leukemia (CML) - genetically a rare event but profound in this pilot study. SETTINGS AND DESIGNS: We explore the possibility of MSI in primary CML patients confirmed by t(9;22) using capillary electrophoresis. Fifteen CML patients and healthy individual samples, respectively, were used to study the markers D17S261 and D3S643. MATERIALS AND METHODS: The DNA was amplified using tagged and nontagged primers and further subjected to bioanalysis and fragment analysis. RESULTS: While the results from bioanalyzer fluctuated, fragment analysis indicated the presence of microsatellite variability in 80% of the patients' samples as compared to no MSI in normal individuals for both the markers. CONCLUSION: These findings suggest that MSI is a genetic event that may have a role in CML progression or evolution. Further studies are warranted to understand the plausible underlying causes.

AB - INTRODUCTION: Rituximab (R)-CHOP improves survival over CHOP in diffuse large B cell lymphoma (DLBCL). The availability of biosimilar rituximab in India has increased access of this drug. We report on the impact of treatment on outcomes with special emphasis on the impact of biosimilar rituximab and radiation. METHODS: Outcomes of adults (age 15-60 years) treated with CHOP+/- Rituximab radiation were analyzed retrospectively to look at baseline features, treatment, and event-free and overall survival (EFS and OS). RESULTS: In the period 2000 2013, 444 patients (median age 47 years: 15-60; males: 288 [65%]; Stage III/IV: 224 [50%]; age-adjusted international prognostic index [aaIPI] Score 2 or 3 in 50%) received either CHOP (n = 325 [73%]) or RCHOP (n = 119 [27%]) therapy. Biosimilar rituximab and the original were used in 95 (80%) and 24 (20%) patients, respectively. Radiation was given in 134 (30%) patients (Stages I and II, 100/220 [45%] and Stages III and IV, 34/224 [15%]). After a median follow-up of 46 (0.2-126) months, the 5-year EFS and OS were 59% and 68%, respectively. The factors predicting inferior EFS and OS were age> 40 years, performance status 2 4, Stage III/IV, hemoglobin <12 g/dL, the aaIPI Score 2 or 3, and nonuse of rituximab and radiation. Radiation used in early stage disease benefitted all subgroups regardless of bulky disease, use of rituximab, or the number of cycles of chemotherapy. Addition of rituximab improved survival across all categories of aaIPI. CONCLUSION: Availability of biosimilar rituximab has increased access and survival of patients with DLBCL in India. Radiotherapy improved outcomes in early stages. PMID- 29469073 TI - ROS1 rearranged nonsmall cell lung cancer and crizotinib: An Indian experience. AB - ROS1 rearrangement acts as a driver mutation in 1-2% of NSCLC. Crizotinib is approved in this situation both in treatment naive and pre-treated patients. Here we report our experience with crizotinib in patients with advanced NSCLC harbouring ROS1 rearrangement. Eleven patients were included in our study. More than half of our patients had associated comorbidities and one fourth of them had a compromised performance status. Out of 11 patients, 5 of them were exposed to crizotinib .The response rates among crizotinib treated patients was 80%. With a median follow up of 9 months, median PFS and OS were 5.4 months and 8.5 months respectively for the entire population. Analyzing the outcomes separately , median PFS and OS was not reached for those who received crizotinib compared to median PFS of 2.5 months and median OS of 4.2 months in those who were not exposed to crizotinib. The difference was statistically significant. Estimated 1 year OS was 80% for those who received crizotinib compared to 18% for who did not receive crizotinib. In conclusion, crizotinib is effective with acceptable side effect profile in patients with ROS1 rearranged NSCLC in our population. PMID- 29469074 TI - Perioperative complications of esophagectomy: Postneoadjuvant treatment versus primary surgery - Our experience and review of literature. AB - AIMS: : To compare perioperative complications in esophagectomy after neoadjuvant therapy v/s primary surgery. SETTINGS AND DESIGN: : Retrospective analysis of perioperative complications in a prospectively maintained data base of patients who underwent esophagectomy as Primary surgery or after neoadjuvant therapy was done. METHODS AND MATERIAL: : 238 cases of esophagectomies performed for esophageal carcinoma were analysed and compared, out of which 125(52.5%) were given neoadjuvant therapy followed by surgery and 113(47.5%) underwent primary surgery. Surgical procedure was standard for both the groups. All the cases were analysed for perioperative complications. STATISTICAL ANALYSIS USED: : Data was analysed using Open Epi soft ware. Association between the two study group was assessed with Chi square test. RESULTS: : On comparison, both the groups were comparable in demographic profile and type of surgery performed. However, tumour stage was higher for cases who received neoadjuvant therapy as expected. On analysis there was no significant difference in overall morbidity and 30 days mortality. CONCLUSIONS: : Neoadjuvant Chemo/chemoradiotherapy is a feasible option in esophageal carcinoma without increase in incidence of peri operative morbidity or mortality. PMID- 29469075 TI - Paralingual and sublingual space invasion in magnetic resonance imaging of squamous cell carcinoma of anterior two-thirds of tongue: Is there a prognostic significance? A prospective evaluation. AB - BACKGROUND: Magnetic resonance imaging (MRI) in tumors of anterior two-thirds of tongue has a significant role in assessing different tumor parameters, and in prognosticating. AIM: This prospective study conducted in a tertiary cancer care center, focused on patients with squamous cell carcinoma of anterior two-thirds of tongue. The significance of invasion of paralingual and sublingual spaces in relation to the pathological grade of these tumors, and its predictive value in pathological nodal involvement were analyzed. MATERIALS AND METHODS: All consecutive patients with the required inclusion criteria were accrued. Imaging was done with 3 Tesla MRI and invasion of sublingual and paralingual spaces were accurately assessed. Data elucidated were tabulated and analysed using IBM SPSS version 20.0. Chi-square test, nonparametric correlation using Spearman's Rho correlation, and two-independent sample test using Mann-Whitney's U-test were used to arrive at correlations between the imaging and histopathological parameters. RESULTS: Sixty-three patients were analyzed. Mean age was 52.3 +/- 11.45 years. 74.6% were males. MRI showed sublingual space invasion in 47.6%. 18/28 with and 11/33 without invasion had node positivity. Paralingual space involvement was observed in 31.7% of patients. Thirteen of these and 16/43 with no involvement had positive cervical nodes. No statistically significant correlation was observed. CONCLUSION: This prospective study did not establish any statistically sound correlation, and robust data are lacking to support newer parameters such as sublingual space and paralingual space as probable predictors of cervical nodal involvement, and for prognostication. PMID- 29469076 TI - Quality of life outcome measures using University of Washington questionnaire version 4 in early T1/T2 anterior tongue cancers with and without radiotherapy: A cross-sectional study. AB - CONTEXT: To evaluate the quality of life (QOL) outcome measures in disease-free survivors of pathological T1/T2 tongue cancers and to compare QOL in patients treated with only surgery and with adjuvant treatment. SETTINGS AND DESIGN: Cross sectional survey. PATIENTS AND METHODS: All pathological T1/T2 anterior tongue cancer cases with follow-up from January 2011 till December 2015, who had locoregionally controlled disease with a minimum disease-free survival period of 1 year, were included in the study. RESULTS: A total of 36 patients, 28 are males and 8 are females with an age range of 24-66 years (median age of 43) were enrolled in the study. The patients were divided into two groups with (n = 26) and without adjuvant postoperative radiotherapy (RT) (n = 10) and the University of Washington-QOL questionnaire version 4 for physical and social domains, global questions and three important domains were analyzed. On the physical and social domain scores, the surgery-alone group outscored the combined modality group on all scales and the differences were statistically significant for specific physical domains such as saliva (0.0001), taste (P = 0.0001), chewing (P = 0.0004), swallowing (P = 0.0026), and social domains such as mood (0.0001), pain (P = 0.0001), and shoulder function (P = 0.0061). The overall global QOL scores were also better for the surgical group compared with group which received adjuvant RT but was not statistically significant. All patients chose saliva as their top priority domain in the group which received radiation, and 60% chose "swallowing ability" as the preferred top priority domain in the only surgical group. CONCLUSIONS: Although locoregional control and disease-free survival are the major treatment-related endpoints for cancer management, QOL outcome measures have to assess to determine the impact of a treatment modality on patients well being and for better rehabilitation of cancer-free patients. PMID- 29469077 TI - Carboplatin-based concurrent chemoradiation therapy in locally advanced head and neck cancer patients who are unfit for cisplatin therapy. AB - BACKGROUND: Cisplatin-based chemoradiation (CTRT) is the standard of care in locally advanced head and neck cancers. Limited treatment options are available in patients unfit for cisplatin. AIMS: This audit was carried out to study the toxicities, tolerance, and outcomes of carboplatin-based CTRT in patients who are not eligible for cisplatin. MATERIALS AND METHODS: A total of 63 locally advanced head and neck cancer patients treated between January 2011 and October 2015 were administered carboplatin-based CTRT. The dose of carboplatin was equivalent to area under the curve equivalent to 2 administered once a week for a maximum of 7 cycles. Toxicity was coded as per the CTCAE version 4.03. SPSS software version 16 was used for statistical analysis. STATISTICAL ANALYSIS: Descriptive statistics was performed. Progression-free survival (PFS) and overall survival (OS) were estimated by Kaplan-Meier survival analysis. Cox proportional hazard model was used for identifying factors affecting PFS and OS. RESULTS: The reasons for patients being unfit for cisplatin were low serum creatinine clearance in 41 (65.07%), sensorineural hearing loss in 18 (28.57%), uncontrolled medical comorbidities in 3 (4.76%), and old age in 1 patient (1.6%). 53 patients (84.1%) completed planned radiotherapy. The median number of chemotherapy cycles administered was 6. Grade 3-4 toxicities were seen in 32 patients (50.8%). The median OS and PFS were 28 months (95% confidence interval [CI]: 20.9-34.6 months) and 17 months (95% CI: 08.2-25.7 months), respectively. Age was the only factor significantly affecting OS and PFS. CONCLUSION: Carboplatin-based CTRT is well tolerated in patients unfit for cisplatin and seems to have superior outcomes than those reported in radical radiotherapy studies. PMID- 29469078 TI - Barriers affecting adherence to radiation treatment and strategies to overcome those barriers. AB - BACKGROUND: The WHO defines adherence as the extent to which a patient's behavior coincides with recommendations from a health-care provider. Nonadherence to cancer treatment has a major impact on the therapeutic outcome. AIM OF THE STUDY: To assess the prevalence of nonadherence to radiation regimen and to analyze the factors that affect adherence to cancer treatment. MATERIALS AND METHODS: Patients receiving radiation treatment in our hospital were screened for adherence to appointment keeping and to the prescribed radiation regimen and patients who had unplanned treatment breaks during treatment were interviewed. Between January and July 2013, we identified 61 patients who had unplanned breaks during treatment. We analyzed the social, emotional, educational, economic, and therapeutic barriers that led to nonadherence. RESULTS: Of the 61 patients who had unplanned breaks during treatment, 54% were males and 46% were females. Fifty seven percent of patients had head and neck cancers and 25% had gynecological cancers. Seventy-one percent of patients were planned for concurrent chemoradiation. The number of days of unplanned treatment breaks ranged from 3 to 27 days. Social and therapeutic barriers were found to be the most common factor that led to nonadherence in these patients. CONCLUSION: Identification of barriers that lead to nonadherence, designing strategies to overcome such barriers and effective communication becomes imperative to ensure uninterrupted treatment. Based on the above analysis, we have designed several strategies to improve adherence to treatment among our patients. PMID- 29469079 TI - Impact of pictorial warning labels on tobacco products among patients attending outpatient department of a dental college in Bangalore city: A cross-sectional study. AB - AIM: The aim of this study is to assess the knowledge, attitude, and impact of pictorial warnings present on tobacco packets among patients attending outpatient department of a dental college of Bangalore city. MATERIALS AND METHODS: A cross sectional study was conducted among 419 patients through convenience sampling, using a structured close-ended questionnaire containing 35 questions. The participants were approached and invited to participate voluntarily. The data obtained were analyzed using descriptive statistics, Chi-square test and ANOVA. RESULTS: Mean age of the participants was 28.1 +/- 7.06 years. Out of total 419 participants, 62.8% were tobacco users. About 40.6% of the participants had average knowledge and only 22.9% had positive attitude regarding the pictorial warnings. Nearly 77.9% of tobacco users had previously attempted decreased frequency of tobacco use and 63.7% had tried quitting the habit. The difference was statistically significant (P < 0.05 Chi-square test and ANOVA). CONCLUSION: The present study revealed that most of study participants have noticed the warnings on tobacco products, and most of them believe that they could understand warning labels. This study also showed that most of study participants believed that pictorial health warnings create awareness about probable health hazards of tobacco use and that these pictorial presentations on tobacco packs positively assist in reducing or quitting tobacco smoking. PMID- 29469080 TI - Role change as breadwinner in cancer caregiving. AB - INTRODUCTION: : Indian families are known for adopting the role of caregiver naturally when someone in the family falls ill to cancer. Although there were strong family structure and system existed here, now the changing family pattern and structure are challenging the role of cancer caregiving as well. OBJECTIVE: : This study analyses the life situation of caregivers of cancer survivors during the course of treatment and attempts to explore the areas of interventions for caregivers themselves. METHODS: : A descriptive research design was adopted for the study. A sample of 40 respondents was chosen for the study through purposive sampling technique. RESULTS: : Majority of the caregivers were females (75%) and fell into the age group of 35 to 45 years (65%). The education among the caregivers was varying between illiteracy to postgraduation. Majority of 95% of them adapted the dual role voluntarily and 85% of them felt that they were finding it very difficult to cope with the dual responsibility. About 60% of them felt that they would fail in their roles and were not satisfied with their performances dually. CONCLUSION: : Adaptation to a dual role involves time factor and as part of care to the caregiver, a guided interaction and orientation towards managing these roles would help them better ways to adapt. Given the scarcity of support system on Indian settings, the caregivers who do dual role have huge responsibility and challenges to deliver quality caregiving and fulfill their other roles as well. It is the duty of the complete health care system to seriously take this into consideration and to act on it. PMID- 29469081 TI - Statins and risk of cancer: A meta-analysis of randomized, double-blind, placebo controlled trials. AB - PURPOSE: Several meta-analyses of randomized controlled trials (RCTs) reported no association between the use of statins and the risk of cancer. However, they included open-label RCTs, which did not use placebo as a control group. This study aimed to evaluate the effect of statins on cancer risk using a meta analysis of randomized, double-blind, placebo-controlled trials (RDBPCTs). METHODS: We searched PubMed, EMBASE, and the Cochrane Library in March 2016. Two individual authors reviewed and selected RDBPCTs based on selection criteria. RESULTS: Out of 676 retrieved articles, a total of 21 RDBPCTs with 65,196 participants (32,618 in the statin group and 32,578 in the placebo group) were included in the meta-analysis. Overall, we found that there was no significant association between the use of statins and the risk of cancer (relative risk 0.97, 95% confidence interval 0.92-1.02, I2 = 0.0%) in a fixed-effect meta analysis. In addition, in the subgroup meta-analyses, no beneficial effect of statins was observed when analyzed by statin type, country, follow-up period, methodological quality, underlying diseases/population, and type of cancer. CONCLUSIONS: The current meta-analysis of RDBPCTs found that there was no association between the use of statins and the risk of cancer. PMID- 29469082 TI - Novel use of bioelectric impedence technique to detect alterations in body composition in advanced small cell lung cancer. AB - BACKGROUND: Malnutrition is frequent in lung cancer and is measured using various tools, including the novel bioelectric impedance technique for measuring body composition. However, the validation of this technique for assessing body composition in advanced small cell lung cancer (SCLC) is untested. METHODS: Forty one treatment naive patients (all males) and an equal number of age- and sex matched controls were evaluated by anthropometric measurements of skinfold thicknesses and body composition parameters such as body fat%, fat mass, fat-free mass (FFM), and total body water (TBW). RESULTS: The mean (SD) age of the patient group was 55.7 (7.5) years, median pack-years was 20 (range, 0-80), and mean (SD) duration of symptoms was 152.6 (153.7) days. Median Karnofsky Performance Scale was 70 (range, 50-90). Majority of our patients (68.3%) were Stage IV followed by Stage III (31.7%). The percentage of patients with low, normal, and high body mass index (BMI) was 31.7%, 61%, and 7.3%, respectively. All components of body composition, i.e., body fat%, FFM, and TBW were significantly lower in patients compared to controls. However, the body composition in patients and controls with normal BMI was similar. The phenomenon of sarcopenia as a cause of cancer cachexia may explain these findings, whereas the combination of loss of body fat and lean body mass may lead to weight loss and reduced BMI. CONCLUSION: Our results indicate that body composition is markedly altered in Indian patients with advanced SCLC. The impact of these parameters on clinically relevant outcomes needs further evaluation. PMID- 29469083 TI - Knowledge, attitude, and practice toward cervical cancer among women attending Obstetrics and Gynecology Department: A cross-sectional, hospital-based survey in South India. AB - INTRODUCTION: Cervical cancer-related deaths among women in India are often due to late diagnosis of disease. Knowledge about disease and early screening is the most effective measure for cervical cancer prevention. Lack of awareness, negative attitude, and poor practice about cervical cancer and screening are the major causes to increase the incidence of disease. AIM: The study is designed to assess knowledge, attitude, and practice (KAP) toward cervical cancer, screening, and prevention. SETTINGS AND DESIGN: A cross-sectional, hospital-based survey was conducted in women attending Obstetrics and Gynecology Department of a secondary care referral hospital. MATERIALS AND METHODS: A total of 403 subjects were enrolled and subjected for interview using prevalidated KAP questionnaire on cervical cancer. STATISTICAL ANALYSIS: Descriptive statistics were used to represent the sociodemographic characteristics and KAP levels. Association of sociodemographic variables with KAP levels is determined using Chi-square test. RESULTS AND DISCUSSION: Most of (301; 74.6%) the respondents had heard about cervical cancer and majority of them are heard from media (168; 41.6%) and friends (83; 20.5%). Most women knew symptoms (259; 64.2%), risk factors (253; 62.7%), screening methods (310; 76.9%), and preventive measures (249; 61.7%) for cervical cancer. More than half of the women (252; 62.5%) having positive attitude toward screening. More than three-fourth of women (349; 86.6%) are not having practice toward cervical cancer screening. Sociodemographic characteristics are strongly associated with KAP levels. CONCLUSION: Although women are having good knowledge, positive attitude toward cervical cancer screening and prevention still there is a gap to transform it into practice. There is a need for more educational programs to connect identified knowledge slits and uplift of regular practice of cervical cancer screening.

AB - BACKGROUND Cisplatin (DDP)-based systemic chemotherapy has been widely used in the treatment of postoperative or advanced NSCLC patients, however, its effective rate is only 14~40%. HIF-2alpha can upregulate drug-resistant-related genes expression and lead to chemotherapy resistance in many tumors. However, little is known about the relationship between HIF-2alpha and chemotherapy resistance of lung cancer cells. MATERIAL AND METHODS In our study, the siRNA expression vectors targeting the HIF-2alpha gene were designed, constructed, and transfected into A549 cells. MTT assay and western blot analysis of P-glycoprotein 1 (P-gp) were used to explore the transfer influence of HIF-2alpha gene silencing on the A549 cells in the cisplatin-based chemotherapy resistance. RESULTS After transfection with the siRNAHIF-2alpha into A549 cells, mRNA and protein expression of HIF-2alpha were downregulated. At the same time, expression of P-gp decreased significantly. Furthermore, the sensitivity to cisplatin significantly increased. CONCLUSIONS The constructed siRNA expression vectors can effectively suppress the expression of HIF-2alpha and P-gp, which then can reverse the chemotherapy resistance of A549 cells. PMID- 29469089 TI - Paraneoplastic autoimmune multi-organ syndrome is a distinct entity from traditional pemphigus subtypes. PMID- 29469090 TI - Sterically controlled mechanochemistry under hydrostatic pressure. AB - Mechanical stimuli can modify the energy landscape of chemical reactions and enable reaction pathways, offering a synthetic strategy that complements conventional chemistry. These mechanochemical mechanisms have been studied extensively in one-dimensional polymers under tensile stress using ring-opening and reorganization, polymer unzipping and disulfide reduction as model reactions. In these systems, the pulling force stretches chemical bonds, initiating the reaction. Additionally, it has been shown that forces orthogonal to the chemical bonds can alter the rate of bond dissociation. However, these bond activation mechanisms have not been possible under isotropic, compressive stress (that is, hydrostatic pressure). Here we show that mechanochemistry through isotropic compression is possible by molecularly engineering structures that can translate macroscopic isotropic stress into molecular-level anisotropic strain. We engineer molecules with mechanically heterogeneous components-a compressible ('soft') mechanophore and incompressible ('hard') ligands. In these 'molecular anvils', isotropic stress leads to relative motions of the rigid ligands, anisotropically deforming the compressible mechanophore and activating bonds. Conversely, rigid ligands in steric contact impede relative motion, blocking reactivity. We combine experiments and computations to demonstrate hydrostatic-pressure-driven redox reactions in metal-organic chalcogenides that incorporate molecular elements that have heterogeneous compressibility, in which bending of bond angles or shearing of adjacent chains activates the metal-chalcogen bonds, leading to the formation of the elemental metal. These results reveal an unexplored reaction mechanism and suggest possible strategies for high-specificity mechanosynthesis. PMID- 29469091 TI - Crowther et al. reply. PMID- 29469092 TI - Structure and mechanogating mechanism of the Piezo1 channel. AB - The mechanosensitive Piezo channels function as key eukaryotic mechanotransducers. However, their structures and mechanogating mechanisms remain unknown. Here we determine the three-bladed, propeller-like electron cryo microscopy structure of mouse Piezo1 and functionally reveal its mechanotransduction components. Despite the lack of sequence repetition, we identify nine repetitive units consisting of four transmembrane helices each which we term transmembrane helical units (THUs)-which assemble into a highly curved blade-like structure. The last transmembrane helix encloses a hydrophobic pore, followed by three intracellular fenestration sites and side portals that contain pore-property-determining residues. The central region forms a 90 A-long intracellular beam-like structure, which undergoes a lever-like motion to connect THUs to the pore via the interfaces of the C-terminal domain, the anchor resembling domain and the outer helix. Deleting extracellular loops in the distal THUs or mutating single residues in the beam impairs the mechanical activation of Piezo1. Overall, Piezo1 possesses a unique 38-transmembrane-helix topology and designated mechanotransduction components, which enable a lever-like mechanogating mechanism. PMID- 29469093 TI - Multi-terminal memtransistors from polycrystalline monolayer molybdenum disulfide. AB - Memristors are two-terminal passive circuit elements that have been developed for use in non-volatile resistive random-access memory and may also be useful in neuromorphic computing. Memristors have higher endurance and faster read/write times than flash memory and can provide multi-bit data storage. However, although two-terminal memristors have demonstrated capacity for basic neural functions, synapses in the human brain outnumber neurons by more than a thousandfold, which implies that multi-terminal memristors are needed to perform complex functions such as heterosynaptic plasticity. Previous attempts to move beyond two-terminal memristors, such as the three-terminal Widrow-Hoff memristor and field-effect transistors with nanoionic gates or floating gates, did not achieve memristive switching in the transistor. Here we report the experimental realization of a multi-terminal hybrid memristor and transistor (that is, a memtransistor) using polycrystalline monolayer molybdenum disulfide (MoS2) in a scalable fabrication process. The two-dimensional MoS2 memtransistors show gate tunability in individual resistance states by four orders of magnitude, as well as large switching ratios, high cycling endurance and long-term retention of states. In addition to conventional neural learning behaviour of long-term potentiation/depression, six-terminal MoS2 memtransistors have gate-tunable heterosynaptic functionality, which is not achievable using two-terminal memristors. For example, the conductance between a pair of floating electrodes (pre- and post-synaptic neurons) is varied by a factor of about ten by applying voltage pulses to modulatory terminals. In situ scanning probe microscopy, cryogenic charge transport measurements and device modelling reveal that the bias induced motion of MoS2 defects drives resistive switching by dynamically varying Schottky barrier heights. Overall, the seamless integration of a memristor and transistor into one multi-terminal device could enable complex neuromorphic learning and the study of the physics of defect kinetics in two-dimensional materials. PMID- 29469094 TI - Importance of investing in adolescence from a developmental science perspective. AB - This review summarizes the case for investing in adolescence as a period of rapid growth, learning, adaptation, and formational neurobiological development. Adolescence is a dynamic maturational period during which young lives can pivot rapidly-in both negative and positive directions. Scientific progress in understanding adolescent development provides actionable insights into windows of opportunity during which policies can have a positive impact on developmental trajectories relating to health, education, and social and economic success. Given current global changes and challenges that affect adolescents, there is a compelling need to leverage these advances in developmental science to inform strategic investments in adolescent health. PMID- 29469096 TI - Palladium-catalysed electrophilic aromatic C-H fluorination. AB - Aryl fluorides are widely used in the pharmaceutical and agrochemical industries, and recent advances have enabled their synthesis through the conversion of various functional groups. However, there is a lack of general methods for direct aromatic carbon-hydrogen (C-H) fluorination. Conventional methods require the use of either strong fluorinating reagents, which are often unselective and difficult to handle, such as elemental fluorine, or less reactive reagents that attack only the most activated arenes, which reduces the substrate scope. A method for the direct fluorination of aromatic C-H bonds could facilitate access to fluorinated derivatives of functional molecules that would otherwise be difficult to produce. For example, drug candidates with improved properties, such as increased metabolic stability or better blood-brain-barrier penetration, may become available. Here we describe an approach to catalysis and the resulting development of an undirected, palladium-catalysed method for aromatic C-H fluorination using mild electrophilic fluorinating reagents. The reaction involves a mode of catalysis that is unusual in aromatic C-H functionalization because no organometallic intermediate is formed; instead, a reactive transition metal-fluoride electrophile is generated catalytically for the fluorination of arenes that do not otherwise react with mild fluorinating reagents. The scope and functional-group tolerance of this reaction could provide access to functional fluorinated molecules in pharmaceutical and agrochemical development that would otherwise not be readily accessible. PMID- 29469097 TI - A surge of light at the birth of a supernova. AB - It is difficult to establish the properties of massive stars that explode as supernovae. The electromagnetic emission during the first minutes to hours after the emergence of the shock from the stellar surface conveys important information about the final evolution and structure of the exploding star. However, the unpredictable nature of supernova events hinders the detection of this brief initial phase. Here we report the serendipitous discovery of a newly born, normal type IIb supernova (SN 2016gkg), which reveals a rapid brightening at optical wavelengths of about 40 magnitudes per day. The very frequent sampling of the observations allowed us to study in detail the outermost structure of the progenitor of the supernova and the physics of the emergence of the shock. We develop hydrodynamical models of the explosion that naturally account for the complete evolution of the supernova over distinct phases regulated by different physical processes. This result suggests that it is appropriate to decouple the treatment of the shock propagation from the unknown mechanism that triggers the explosion.

Together with findings in developmental science, our life history analysis indicates that adolescence is a distinctive period for biological embedding of culture. Ethnographic evidence shows that mass education is a novel feature of the globalizing cultural configurations of adolescence, which are driven by transformations in labour, livelihood and lifestyle. Evaluation of the life history trade-offs and sociocultural ecologies that are experienced by adolescents may offer a practical basis for enhancing their development.

AB - BACKGROUND: Leri-Weill syndrome (LWS) ranks among conditions with short stature homeobox gene (SHOX) haploinsufficiency. Data on possible association of SHOX aberrations with malignant diseases are scarce. METHODS AND RESULTS: We report a unique case of an 8-year-old girl who was successfully treated for acute lymphoblastic leukemia (pre-B ALL, intermediate risk) and was subsequently diagnosed with LWS due to characteristic clinical appearance (short disproportionate stature, Madelung deformity of the wrist) and molecular genetic examination (complete deletion of SHOX). An identical SHOX deletion was identified also in the patient's mother. Leukemic cells of the patient were retrospectively examined by array comparative genomic hybridization (aCGH), which revealed five regions of deletions at chromosome X, including the SHOX gene locus. CONCLUSION: Growth retardation in children with hemato-oncologic malignancies cannot always be attributed to cytotoxic treatment and should be carefully evaluated, especially with regards to growth hormone therapy.

AB - Process-stable complexes composed of whey protein isolate (WPI) and sugar beet pectin have great potential as structuring agents or fat replacers in foods. The current study investigates the compatibility of heated WPI : pectin complexes in different meat matrices. Spreadable raw-fermented sausages and sliceable emulsion type sausages were therefore manufactured containing biopolymer complexes with various WPI : pectin ratios r (2 : 1, 8 : 1). Macro- and microstructural properties of the meat dispersions were analyzed in terms of colour, texture, rheometry, sensory, and confocal laser scanning microscopy (CLSM) measurements. Textural and sensorial results demonstrated that the meat products became increasingly soft and yellowish as the biopolymer ratio r was increased regardless of the meat matrix, whereas pH and water activity values were not affected. CLSM images revealed that the meat protein network became disrupted and loose in the presence of pectin, which was attributed to a thermodynamic incompatibility effect. The results obtained from this study highlight that biopolymer complexes might be suitable fat mimetics, particularly for spreadable meat products.

AB - Crystallization of membrane proteins is a critical step for uncovering atomic resolution 3-D structures and elucidating structure-function relationships. Microseeding, the process of transferring sub-microscopic crystal nuclei from initial screens into new crystallization experiments, is an effective, yet underutilized approach to grow crystals suitable for X-ray crystallography. Here, we report simplified methods for crystallization of membrane proteins that utilize microseeding in X-ray transparent microfluidic chips. First, a microfluidic method for introduction of microseed dilutions into metastable crystallization experiments is demonstrated for photoactive yellow protein and cytochrome bo3 oxidase. As microseed concentration decreased, the number of crystals decreased while the average size increased. Second, we demonstrate a microfluidic chip for microseed screening, where many crystallization conditions were formulated on-chip prior to mixing with microseeds. Crystallization composition, crystal size, and diffraction data were collected and mapped on phase diagrams, which revealed that crystals of similar diffraction quality and size typically grow in distinct regions of the phase diagram.

AB - Herein, we report the synthesis of gold (Au)-loaded mesoporous iron oxide (Fe2O3) as a catalyst for both CO and NH3 oxidation. The mesoporous Fe2O3 is firstly prepared using polymeric micelles made of an asymmetric triblock copolymer poly(styrene-b-acrylic acid-b-ethylene glycol) (PS-b-PAA-b-PEG). Owing to its unique porous structure and large surface area (87.0 m2 g-1), the as-prepared mesoporous Fe2O3 can be loaded with a considerably higher amount of Au nanoparticles (Au NPs) (7.9 wt%) compared to the commercial Fe2O3 powder (0.8 wt%). Following the Au loading, the mesoporous Fe2O3 structure is still well retained and Au NPs with varying sizes of 3-10 nm are dispersed throughout the mesoporous support. When evaluated for CO oxidation, the Au-loaded mesoporous Fe2O3 catalyst shows up to 20% higher CO conversion efficiency compared to the commercial Au/Fe2O3 catalyst, especially at lower temperatures (25-150 degrees C), suggesting the promising potential of this catalyst for low-temperature CO oxidation. Furthermore, the Au-loaded mesoporous Fe2O3 catalyst also displays a higher catalytic activity for NH3 oxidation with a respectable conversion efficiency of 37.4% compared to the commercial Au/Fe2O3 catalyst (15.6%) at 200 degrees C. The significant enhancement in the catalytic performance of the Au loaded mesoporous Fe2O3 catalyst for both CO and NH3 oxidation may be attributed to the improved dispersion of the Au NPs and enhanced diffusivity of the reactant molecules due to the presence of mesopores and a higher oxygen activation rate contributed by the increased number of active sites, respectively. PMID- 29469139 TI - Entropic trap purification of long DNA. AB - Long-read genomic applications, such as genome mapping in nanochannels, require long DNA that is free of small-DNA impurities. We have developed a chip-based system based on entropic trapping that can simultaneously concentrate and purify a long DNA sample under the alternating application of an applied pressure (for sample injection) and an electric field (for filtration and concentration). In contrast, short DNA tends to pass through the filter owing to its comparatively weak entropic penalty for entering the nanoslit. The single-stage prototype developed here, which operates in a continuous pulsatile manner, achieves selectivities of up to 3.5 for lambda-phage DNA (48.5 kilobase pairs) compared to a 2 kilobase pair standard based on experimental data for the fraction filtered using pure samples of each species. The device is fabricated in fused silica using standard clean-room methods, making it compatible for integration with long read genomics technologies.

AB - Oxazoline-containing ligands have been widely employed in numerous asymmetric catalytic reactions. Pyridine-oxazoline-type ligands, a class of hybrid ligands, were designed earlier than bisoxazoline and phosphine-oxazoline ligands; however, their unique properties have only been discovered recently. Pyridine-oxazoline type chiral ligands are rapidly becoming popular for use in asymmetric catalysis, especially for several new and efficient asymmetric methodologies. Several types of challenging asymmetric reactions have been discovered recently using pyridine oxazoline-type ligands showing their special properties and potential for future application in a wide range of new catalytic methodologies. This review provides an overview of this field, with the aim of highlighting both ligand design and synthetic methodology development. PMID- 29469143 TI - A little key to oxalate formation in oil paints: protective patina or chemical reactor? AB - By means of synchrotron based techniques, we propose an integrated mechanism for the degradation of 19th century chrome yellow oil paints based on pigment reconstructions from historical recipes. We show that for certain paint formulations the darkening of these colours is triggered by the binder photodegradation which leads to the formation of calcium oxalate at the expense of the filler CaCO3, and the reduction of the chrome yellow pigment (Cr6+/Cr3+). Considering that calcium oxalate is formed as a thin superficial layer, that may prevent light absorption by the paint bulk, we discuss its role as protective patina. PMID- 29469144 TI - Identification of a novel ligand for the ATAD2 bromodomain with selectivity over BRD4 through a fragment growing approach. AB - ATAD2 is an ATPase that is overexpressed in a variety of cancers and associated with a poor patient prognosis. This protein has been suggested to function as a cofactor for a range of transcription factors, including the proto-oncogene MYC and the androgen receptor. ATAD2 comprises an ATPase domain, implicated in chromatin remodelling, and a bromodomain which allows it to interact with acetylated histone tails. Dissection of the functional roles of these two domains would benefit from the availability of selective, cell-permeable pharmacological probes. An in silico evaluation of the 3D structures of various bromodomains suggested that developing small molecule ligands for the bromodomain of ATAD2 is likely to be challenging, although recent reports have shown that ATAD2 bromodomain ligands can be identified. We report a structure-guided fragment based approach to identify lead compounds for ATAD2 bromodomain inhibitor development. Our findings indicate that the ATAD2 bromodomain can accommodate fragment hits (Mr < 200) that yield productive structure-activity relationships, and structure-guided design enabled the introduction of selectivity over BRD4. PMID- 29469145 TI - Conductive 3D sponges for affordable and highly-efficient water purification. AB - Effective, affordable and low energy water purification technologies are highly desirable to address the current environmental issues. In this study, we developed a low-cost method to achieve efficient organic pollutants degradation by incorporating conductive nanomaterials (i.e., carbon nanotubes, CNTs) to assist electro-oxidation, leading to an efficient conductive nano-sponge filtration device. The integration of electrochemistry has significantly improved the performance of the sponge-based device to adsorb and oxidize organic compounds in aqueous solution. In particular, CNT materials could serve as both high-performance electro-catalysts for pollutant degradation and conductive additives that make polyurethane sponges highly conductive. On the other hand, the polyurethane sponge could work as a low-cost and highly porous matrix that could effectively host these CNT conductors. The conductive sponge can be easily fabricated by a simple dying based approach. The as-fabricated gravity fed device could effectively oxidize two model organic compounds (i.e., >92% antibiotic tetracycline and >94% methyl orange) via a single pass through the conductive sponge under the optimized experimental conditions (e.g., [Na2SO4] = 10 mmol L-1, [CNT] = 0.3 mg mL-1, and [SDBS] = 2.0 mg mL-1). We have achieved >88% degradation efficiency for the antibiotic tetracycline within 6 h of continuous operation with an average electro-oxidation flux of 0.82 +/- 0.05 mol h-1 m-2 and an energy requirement of 1.0 kW h kg-1 COD or <0.02 kW h m-3. These promising data make our CNT-sponge filtration device attractive for affordable and effective water purification. PMID- 29469146 TI - Nanocomposites based on hierarchical porous carbon fiber@vanadium nitride nanoparticles as supercapacitor electrodes. AB - In this study, a hybrid electrode material for supercapacitors based on hierarchical porous carbon fiber@vanadium nitride nanoparticles is fabricated using the method of phase-separation mediated by the PAA-b-PAN-b-PAA tri-block copolymer. In the phase-separation procedure, the ionic block copolymer self assembled on the surface of carbon nanofibers, and is used to adsorb NH4VO3. Thermal treatment at controlled temperatures under an NH3 : N2 atmosphere led to the formation of vanadium nitride nanoparticles that are distributed uniformly on the nanofiber surface. By changing the PAN to PAA-b-PAN-b-PAA ratio in the casting solution, a maximum specific capacitance of 240.5 F g-1 is achieved at the current density of 0.5 A g-1 with good rate capability at a capacitance retention of 72.1% at 5.0 A g-1 in an aqueous electrolyte of 6 mol L-1 KOH within the potential range of -1.10 to 0 V (rN/A = 1.5/1.0). Moreover, an asymmetric supercapacitor is assembled by using the hierarchical porous carbon fiber@vanadium nitride as the negative electrode and Ni(OH)2 as the positive electrode. Remarkably, at the power density of 400 W kg-1, the supercapacitor device delivers a better energy density of 39.3 W h kg-1. It also shows excellent electrochemical stability, and thus might be used as a promising energy-storage device.

AB - An efficient method for the synthesis of isoquinolino[1,2-b]quinazolin-8-one derivatives and 12-methyl-12H-isoindolo[1,2-b]quinazoline-10-one derivatives is described herein. With rhodium catalysis, the desired products are obtained through a sequence reaction of C-H activation-based alkenylation and intramolecular aza-Heck-type cyclization. The developed method has a wide range of substrate tolerance under mild conditions and provides an alternative for the structural elaboration of quinazoline compounds. PMID- 29469148 TI - Advances in point-of-care diagnostic devices in cancers. AB - The early diagnosis and monitoring of the progress of cancers are limited due to the lack of adequate screening tools. Ultrasensitive and precise point-of-care cancer diagnostic tools are required for the early detection and screening of cancer biomarkers at the bedside with accuracy and specificity of diagnosis. Recent advances in nano- and microfabrication based technologies integrated with different sensing platforms are accelerating the development of rapid, low-cost and reliable point-of-care cancer diagnostic devices. These technologies allow low volumes of reagents and samples, reduced analysis time, are disposable and portable, and provide ultrasensitive multiplexed analysis to improve diagnostic and prognostic evaluations. Networking for communicating and transferring the results through wireless networks provides additional opportunities for remote telemedicine-based diagnosis and planning of treatment regimens, even in semi urban and rural areas. This review focuses on recent advances in point-of-care cancer diagnostics for efficient treatment along with the key challenges, opportunities and future scope of these technologies for clinical translation. PMID- 29469149 TI - Technical aspects of nicking enzyme assisted amplification. AB - Nicking enzyme assisted amplification (NEAA) is an extremely rapid method for molecular diagnosis. However, this technology is not widely applied for real sample analysis because the overproduced non-specific products limit its sensitivity and raise the threshold of detection methods. Here, we have found that the non-specific amplification is mainly caused by the coexistence of Bst polymerase, nicking primers and dNTP. The highly active nicking enzyme directs and accelerates the non-specific amplification in a way which favors nicking. To suppress the non-specific amplification, the nicking enzyme concentration, reaction temperature, and magnesium ion concentration are optimized. The compatibility of Bst polymerase with the concentration of the monovalent cation is also crucial. Besides, the sensitivity could be enhanced by shortening the target sequences and priming the 3' end of the target.

AB - Alkane guest transfer into aqueous dimeric, tetrameric, hexameric, and octameric assemblies of the deep-cavity cavitand TEMOA is examined using molecular simulations. The experimental transitions between aggregation states strongly correlate with calculated alkane transfer free energy minima, demonstrating the guiding role of guest packing on stabilizing multimeric complexes. The predictive simulation approach described affords a salient rationale as to why octameric assemblies have yet to be experimentally observed.

AB - Two cationic molecular rotors, 1 and 2, capable of real-time cell-cycle imaging by specifically dynamic monitoring of nucleolus and chromosome changes were developed. A further study shows that fluorescence enhancements in the nucleolus and chromosome are attributed to a combination effect of interaction with nucleic acid and high condensation of the nucleolus and chromosome. PMID- 29469158 TI - A novel potentiometric immunoassay for carcinoma antigen 15-3 by coupling enzymatic biocatalytic precipitation with a nanogold labelling strategy. AB - Methods based on potentiometric measurement have been developed for immunoassays, but most exhibit low sensitivities and are unsuitable for early diagnosis of disease. Herein we design a new potentiometric immunosensing platform for the sensitive detection of carcinoma antigen 15-3 (CA 15-3) by coupling with enzymatic biocatalytic precipitation and a nanogold labeling technique. The sandwich-type immunoreaction is carried out on a monoclonal anti-CA 15-3 capture antibody-modified working electrode, using horseradish peroxidase (HRP) and polyclonal anti-CA 15-3 detection antibody-labeled gold nanoparticles. Upon the introduction of target CA 15-3, the carried HRP molecules with an immunocomplex catalyze the oxidation of 4-chloro-1-naphthol (4-CN) into the insoluble benzo-4 chlorohexadienone. The formed product coated on the surface of the modified electrode results in a change of the electrical potential. Under optimal conditions, the shift in the electrical potential relative to the background signal increases with the increasing target CA 15-3 concentration, and exhibits a good linear relationship within the dynamic range of 0.01-30 U mL-1 at a detection limit of 7.8 mU mL-1. Good precision and reproducibility, and high specificity were acquired for the analysis of 15 human serum specimens, giving well matched results with those obtained from a human CA 15-3 ELISA kit. PMID- 29469160 TI - trans to cis photo-isomerization in merocyanine dysprosium and yttrium complexes. AB - We report the synthesis of two lanthanide complexes including a chelating merocyanine (MC) ligand obtained from the reaction of a bis(pyridinemethyl)amine substituted spiropyran with yttrium(iii) or dysprosium(iii) triflate salts, whose structures were confirmed both in the solid state and in solution by single crystal X-ray diffraction studies and NMR investigations. The obtained merocyanine metal complexes can reversibly undergo a photo-triggered transformation consisting of a partial isomerization of the trans-merocyanine ligand to its cis isomer (cis-MC) providing complexes in which the metal phenolate bond is retained. SQUID magnetometry experiments in combination with ab initio calculations were used to evidence and rationalize the single-molecule magnet behavior of the dysprosium complex and to probe the changes in the dysprosium ion local environment upon photo-isomerization. PMID- 29469161 TI - Electrochemical method for the quantitative determination of Escherichia coli based on gold functionalized FTO substrate. AB - This work presents a novel rapid and sensitive label-free electrochemical method for the detection of bacteria on surface nanostructures. A simple electrochemical deposition and calcination method is employed to prepare different gold nanostructures on FTO substrate. The sensor based on nanostructure gold exhibits excellent linear relation between E. coli DH5alpha bacteria and the changes of DeltaRct, especially FTO-GEDC-D30, with a correction coefficient R2 = 0.998. Both the spectrophotometric (OD600 methods) and fluorescence-staining methods also verified the reliability of electrochemical impedance spectroscopy (EIS) methods for evaluating the antibacterial activity of the gold nanostructure. PMID- 29469162 TI - Investigating enhanced thermoelectric performance of graphene-based nano structures. AB - Recently, it has been demonstrated that graphene nano-ribbons (GNRs) exhibit superior thermoelectric performance compared to graphene sheets. However, the underlying mechanism behind this enhancement has not been systematically investigated and significant opportunity remains for further enhancement of the thermoelectric performance of GNRs by optimizing their charge carrier concentration. In this work, we modulate the carrier concentration of graphene based nano-structures using a gate voltage and investigate the resulting carrier concentration-dependent thermoelectric parameters using the Boltzmann transport equations. We investigate the effect of energy dependent scattering time and the role of substrate-induced charge carrier fluctuation in optimizing the Seebeck coefficient and power factor. Our approach predicts the scattering mechanism and the extent of the charge carrier fluctuation in different samples and explains the enhancement of thermoelectric performance of GNR samples. Subsequently, we propose a route towards the enhancement of thermoelectric performance of graphene based devices which can also be applied to other two-dimensional materials. PMID- 29469163 TI - A method for characterising human intervertebral disc glycosaminoglycan disaccharides using liquid chromatography-mass spectrometry with multiple reaction monitoring. AB - Intervertebral disc (IVD) degeneration results in the depletion of proteoglycans and glycosaminoglycans (GAGs), which can lead to structural and mechanical loss of IVD function, ingrowth of nociceptive nerve fibres and eventually discogenic pain. Specific GAG types as well as their disaccharide patterns can be predictive of disease and degeneration in several tissues but have not been comprehensively studied within the IVD. A highly sensitive mass spectrometry based technique with multiple reaction monitoring (MRM) was used to provide characterisation of chondroitin sulphate (CS), hyaluronic acid (HA), heparan sulphate (HS) and their disaccharide sulphation patterns across different anatomical regions of human IVDs. Principal component analysis further distinguished important regional variations and proposed potential ageing variations in GAG profiles. CS was the GAG in greatest abundance in the IVD followed by HA and HS. Principal component analysis identified clear separation of GAG profiles between nucleus pulposus and annulus fibrosus in young and old specimens. Distinct patterns of predominantly expressed disaccharides of CS and HS between young and old IVD samples, provided preliminary evidence that important alterations in disaccharides occur within IVDs during ageing. This technique offered a novel approach to identify and quantify specific GAG disaccharides in human IVDs and the data presented were the first to offer insight into the spatial distribution as well as association with ageing of GAGs and GAG disaccharide sulphation patterns across the human IVD. PMID- 29469164 TI - Heart rate variability affected by radiofrequency electromagnetic field in adolescent students. AB - This study examines the possible effect of radiofrequency (RF) electromagnetic fields (EMF) on the autonomic nervous system (ANS). The effect of RF EMF on ANS activity was studied by measuring heart rate variability (HRV) during ortho clinostatic test (i.e., transition from lying to standing and back) in 46 healthy grammar school students. A 1788 MHz pulsed wave with intensity of 54 +/- 1.6 V/m was applied intermittently for 18 min in each trial. Maximum specific absorption rate (SAR10 ) value was determined to 0.405 W/kg. We also measured the respiration rate and estimated a subjective perception of EMF exposure. RF exposure decreased heart rate of subjects in a lying position, while no such change was seen in standing students. After exposure while lying, a rise in high frequency band of HRV and root Mean Square of the Successive Differences was observed, which indicated an increase in parasympathetic nerve activity. Tympanic temperature and skin temperature were measured showing no heating under RF exposure. No RF effect on respiration rate was observed. None of the tested subjects were able to distinguish real exposure from sham exposure when queried at the end of the trial. In conclusion, short-term RF EMF exposure of students in a lying position during the ortho-clinostatic test affected ANS with significant increase in parasympathetic nerve activity compared to sham exposed group.

AB - NEW FINDINGS: What is the central question of this study? What is the effect of exercise intensity on circulating microparticle populations in young, healthy men and women? What is the main finding and its importance? Acute, moderate-intensity continuous exercise and high-intensity interval exercise altered distinct microparticle populations during and after exercise in addition to a sex-specific response in CD62E+ microparticles. The microparticles studied contribute to cardiovascular disease progression, regulate vascular function and facilitate new blood vessel formation. Thus, characterizing the impact of intensity on exercise induced microparticle responses advances our understanding of potential mechanisms underlying the beneficial vascular adaptations to exercise. ABSTRACT: Circulating microparticles (MPs) are biological vectors of information within the cardiovascular system that elicit both deleterious and beneficial effects on the vasculature. Acute exercise has been shown to alter MP concentrations, probably through a shear stress-dependent mechanism, but evidence is limited. Therefore, we investigated the effect of exercise intensity on plasma levels of CD34+ and CD62E+ MPs in young, healthy men and women. Blood samples were collected before, during and after two energy-matched bouts of acute treadmill exercise: interval exercise (10 * 1 min intervals at ~95% of maximal oxygen uptake VO2max) and continuous exercise (65% VO2max). Continuous exercise, but not interval exercise, reduced CD62E+ MP concentrations in men and women by 18% immediately after exercise (from 914.5 +/- 589.6 to 754.4 +/- 390.5 MPs MUl-1 ; P < 0.05), suggesting that mechanisms underlying exercise-induced CD62E+ MP dynamics are intensity dependent. Furthermore, continuous exercise reduced CD62E+ MPs in women by 19% (from 1030.6 +/- 688.1 to 829.9 +/- 435.4 MPs MUl-1 ; P < 0.05), but not in men. Although interval exercise did not alter CD62E+ MPs per se, the concentrations after interval exercise were higher than those observed after continuous exercise (P < 0.05). Conversely, CD34+ MPs did not fluctuate in response to short-duration acute continuous or interval exercise in men or women. Our results suggest that exercise-induced MP alterations are intensity dependent and sex specific and impact MP populations differentially.

AB - Chondrosarcoma (CS) is a cartilage malignancy of adulthood that is treated by surgery alone, since chemotherapy is considered ineffective. Unfortunately, a large proportion of patients with CS develop lung metastases, and several die of the disease. In this study, we compared 3D-spheroid cultures and conventional cell monolayer models in order to identify the best way to select anticancer agents that could be effective for the systemic control of CS. Using SW1353 cells, we developed a three-dimensional (3D) in vitro culture model to mimic in vivo features of CS microenvironment and evaluated the efficacy of different drugs to modulate CS cell proliferation and survival in 2D versus 3D-cultures. Doxorubicin (DXR) and cisplatin, that are widely employed in sarcomas, were less effective on 3D-CS spheroids when compared to standard monolayer models, whereas treatment with the ionophore salinomycin (SAL) had a strong cytotoxic effect both on 2D and 3D-cultures. Furthermore, as demonstrated by the reduced viability and the enhanced DXR nuclear localization, SAL enhanced DXR cytotoxicity in 3D-CS spheroids also at sub-lethal doses. SAL activity on 3D-CS spheroids was mediated by a significant induction of apoptosis via caspase activation. This study demonstrates that preclinical tests significantly differ in monolayer and 3D cultures of CS cells. Using this approach, SAL, alone or, at sub-lethal concentrations, in combination with DXR, represents a promising agent for the systemic treatment of CS. (c) 2018 Orthopaedic Research Society.

AB - Current guidelines for diabetes recommend that physicians attain a glycated haemoglobin (HbA1c) concentration <=7.0%, but this target may not be applicable to those with heart failure. Fourteen studies in patients with chronic heart failure that examined the relationship between the level of HbA1c and risk of death specified whether HbA1c was influenced by treatment with antidiabetic medications. In patients with heart failure not receiving glucose-lowering drugs, the mortality rate was not higher among those with an HbA1c concentration <7.0%. By contrast, in patients who were treated with insulin, sulphonylureas and thiazolidinediones, an inverse or U-shaped relationship between HbA1c and the risk of death was generally observed, and mortality was lowest in patients with both heart failure and diabetes if the level of HbA1c was >7.0%. These studies suggest that patients with both heart failure and diabetes are at increased risk of death if they are prescribed certain glucose-lowering drugs to achieve levels of HbA1c <7.0%.

AB - The principal purpose of the present work is to characterize the aroma, aroma active, and anthocyanin profiles of Okuzgozu wines and to observe the effect of the pomace pressing technique on these parameters. A total of 58 and 59 volatile compounds were identified and quantified in free-run juice wine (FRW) and pressed pomace wine (PW). Alcohols were found as the most dominant group among aroma compounds followed by esters and acids. However, among all these compounds, only 11 and 13 of them could be considered as key odorants in aromatic extracts of FRW and PW, respectively. According to GC-MS-O analysis, ethyl octanoate (fruity), phenyl ethyl acetate (fruity), and 2-phenyl ethanol (flowery) were found as the main contributors to the overall scent of both wines. Beyond the aroma profiles, anthocyanin contents of both types of wines were also investigated, and total 14 and 15 anthocyanins were identified and quantified in FRW and PW. Malvidin-3 glycoside and its acetyl and coumaroyl forms were identified as the dominant anthocyanins in both wines. It is worth noting the pressing application (2.0 atm) led to an increase of some unpleasant notes in the aroma providing chemical, pharmacy, and fermented aromas in wine. On the other hand, the wines produced with pressed pomace presented higher amounts of anthocyanins. PMID- 29469169 TI - Alimentary microbes of winter-form Drosophila suzukii. AB - Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) is a damaging pest of fruit. Reproductively diapausing adults overwinter in woodlands and remain active on warmer winter days. It is unknown if this adult phase of the lifecycle feeds during the winter period, and what the food source may be. This study characterized the flora in the digestive tract of D. suzukii using a metagenomics approach. Live D. suzukii were trapped in four woodlands in the south of England and their guts dissected for DNA extraction and amplicon-based metagenomics sequencing (internal transcribed spacer and 16S rRNA). Analysis at genus and family taxonomic levels showed high levels of diversity with no differences in digestive tract bacterial or fungal biota between woodland sites of winter-form D. suzukii. Female D. suzukii at one site appeared to have higher bacterial diversity in the alimentary canal than males, but there was a site, sex interaction. Many of the biota were associated with cold, wet climatic conditions and decomposition. This study provides the first evidence that winter-form D. suzukii may be opportunistic feeders during the winter period and are probably exploiting food sources associated with moisture on decomposing vegetation during this time. A core gut microbiome has been identified for winter-form D. suzukii.

AB - PROBLEM: Is sensitization to atopic reaction related to treatment response of recurrent Candida vulvovaginal (RVVC)? METHOD OF THE STUDY: Analysis of ReCiDiF trial data of optimal (OR) and non-responders (NR) to fluconazole maintenance treatment, to explore medical history, physical status, family history, and vaginal immune response for potential sensitization to atopic reaction. RESULTS: Sociodemographic characteristics of 33 NR women were not different from 38 OR. NR had received higher number of different treatments (mean difference 1.6 different treatments (95% CI: 0.20-2.97), P = .03) and had more episodes of disease (P < .05). Multivariate regression analysis showed that family history of atopy (OR: 4.9, CI 95%: 1.1-22.2), duration of symptoms (OR: 1.2, CI 95%: 1.02-1.5), and vulvar excoriation (OR: 3.6, CI 95%: 1.4-9.3) were related to non-response. Vulvar excoriation at entry was the only statistically significant predictive factor for non-response in multivariate analysis with specificity 77.8% and sensitivity 51.6%. CONCLUSION: Women with RVVC with vulvar excoriation, longer duration of disease, and family history of atopic disease are at increased risk not to respond to maintenance fluconazole treatment.

AB - BACKGROUND: Nuchal translucency measurement has an established role in first trimester screening. Accurate measurement requires that technical guidelines are followed. Performance can be monitored by auditing the distribution of measurements obtained in a series of cases. AIMS: The primary aim is to develop an accessible, theory-based educational program for individuals whose distribution of measurements at audit falls outside an acceptable range, and assess operator performance following this intervention. MATERIALS AND METHODS: Operators whose nuchal translucency measurement distributions fall outside a normal range (38-65% above the median) were expected to undergo a teleconference tutorial. Accessible from anywhere in Australia, the one hour tutorials were run by a senior sonographer (to explain technical ultrasound aspects) and the audit program manager (to explain the audit process). RESULTS: In 2011, 83 operators attended the teleconference tutorials. Compared to a random comparison group of operators meeting standard in 2011, teleconference tutorial attendees were significantly more likely to: (i) operate in rural or regional, rather than metropolitan, centres (P = 0.001); (ii) be less experienced (P < 0.0005); and (iii) have lower annual scan numbers (P = 0.0012). Improvement in nuchal translucency measurement quality was seen after one audit cycle and was maintained over subsequent years. The mean percentage of the study cohort reaching standard over the five-year audit was 77.8% which was not statistically different from the average for the comparison cohort of all other audited operators (79.3%; P = 0.61). CONCLUSIONS: Teleconference tutorials are a convenient, accessible and effective way to obtain immediate and sustained improvement in operator performance.

AB - Manual segmentation is a significant obstacle in the analysis of compositional MRI for clinical decision-making and research. Our aim was to produce a fast, accurate, reproducible, and clinically viable semi-automated method for segmentation of hip MRI. We produced a semi-automated segmentation method for cartilage segmentation of hip MRI sequences consisting of a two step process: (i) fully automated hierarchical partitioning of the data volume generated using a bespoke segmentation approach applied recursively, followed by (ii) user selection of the regions of interest using a region editor. This was applied to dGEMRIC scans at 3T taken from a prospective longitudinal study of individuals considered at high-risk of developing osteoarthritis (SibKids) which were also manually segmented for comparison. Fourteen hips were segmented both manually and using our semi-automated method. Per hip, processing time for semi-automated and manual segmentation was 10-15, and 60-120 min, respectively. Accuracy and Dice similarity coefficient (DSC) for the comparison of semi-automated and manual segmentations was 0.9886 and 0.8803, respectively. Intra-observer and inter observer reproducibility of the semi-automated segmentation method gave an accuracy of 0.9997 and 0.9991, and DSC of 0.9726 and 0.9354, respectively. We have proposed a fast, accurate, reproducible, and clinically viable semi automated method for segmentation of hip MRI sequences. This enables accurate anatomical and biochemical measurements to be obtained quickly and reproducibly. This is the first such method that shows clinical applicability, and could have large ramifications for the use of compositional MRI in research and clinically. (c) 2018 Orthopaedic Research Society.

AB - Supported bimetallic catalysts have been studied because of their enhanced catalytic properties due to metal-metal interactions compared with monometallic catalysts. We focused on galvanic deposition (GD) as a bimetallization method, which achieves well-defined metal-metal interfaces by exchanging heterogeneous metals with different ionisation tendencies. We have developed Ni@Ag/SiO2 catalysts for CO oxidation, Co@Ru/Al2 O3 catalysts for automotive three-way reactions and Pd-Co/Al2 O3 catalysts for methane combustion by using the GD method. In all cases, the catalysts prepared by the GD method showed higher catalytic activity than the corresponding monometallic and bimetallic catalysts prepared by the conventional co-impregnation method. The GD method provides contact between noble and base metals to improve the electronic state, surface structure and reducibility of noble metals.

AB - The toxic effect of ethanol is one of the most important handicaps for many biotechnological applications of yeasts, such as bioethanol production. Elucidation of ethanol stress response will help to improve yeast performance in biotechnological processes. In the yeast Saccharomyces cerevisiae, ethanol stress has been recently described as an activator of the unfolded protein response (UPR), a conserved intracellular signalling pathway that regulates the transcription of ER homoeostasis-related genes. However, the signal and activation mechanism has not yet been unravelled. Here, we studied UPR's activation after ethanol stress and observed the upregulation of the key target genes, like INO1, involved in lipid metabolism. We found that inositol content influenced UPR activation after ethanol stress and we observed significant changes in lipid composition, which correlate with a major membrane fluidity alteration by this amphipathic molecule. Then, we explored the hypothesis that membrane fluidity changes cause UPR activation upon ethanol stress by studying UPR response against fluidification or rigidification agents and by studying a mutant, erg2, with altered membrane fluidity. The results suggest that the membrane fluidification effects of ethanol and other agents are the signal for UPR activation, a mechanism that has been proposed in higher eukaryotes.

AB - BACKGROUND: Tennis elbow is a common painful condition that may affect daily function and ability to work. Physiotherapy is the most commonly used primary intervention but there is a wide range of treatment options within the umbrella of physiotherapy. Our aim was to report on the treatments that are currently used by physiotherapists in a UK National Health Service (NHS) setting. METHODS: A retrospective service evaluation was conducted at two NHS hospital trusts by reviewing patient attendance records over a 1-year period. All patients with tennis elbow were included, except those referred for postoperative rehabilitation. Patient notes were analysed using a predefined assessment template. RESULTS: A total of 65 patient records were identified, with patients having a mean age 48 years and mean symptom duration of 5.4 months. The mean treatment duration was 64 days, over 3.7 sessions. The most commonly used treatments were education and exercise, although the type and dosing of exercise varied greatly. Passive modalities such as ice, taping, manual therapy, acupuncture and electrotherapy were still used. CONCLUSIONS: Wide variations in treatment approaches were identified. There was no consistency in the choice of modality used, the type of exercise or the dose of exercise prescribed. The use of passive modalities and corticosteroid injections was found to remain commonplace, despite a lack of supporting research evidence. There is a clear need for evidence-based guidance for physiotherapists treating patients with tennis elbow. PMID- 29469175 TI - Presence of autoimmune disease affects not only risk but also survival in patients with B-cell non-Hodgkin lymphoma. AB - Although autoimmune diseases (AIDs) are known to predispose to non-Hodgkin lymphoma (NHL), their association with NHL prognosis has rarely been investigated. We examined associations between autoimmunity and B-cell NHL onset by comparing AID history (determined by self-report and medication review and supplemented by chart review where possible) among 435 adult B-NHL patients in Hadassah-Hebrew University Medical Center, diagnosed 2009-2014, and 414 age-and sex frequency-matched controls. We examined AIDs as a whole, B- and T-cell mediated AIDs, and autoimmune thyroid diseases. Among cases, we used Kaplan-Meier and Cox regression models to assess the association of AID with overall survival and relapse-free survival, adjusting for prognostically important patient and disease characteristics such as Ki67% staining, International Prognostic Index, rituximab treatment, and histological subgroup. Autoimmune diseases were associated with B-NHL (odds ratio [OR] = 1.95; 95% confidence interval (CI), 1.31 2.92), especially AIDs mediated by B-cell activation (OR = 5.20; CI, 1.90-14.3), which were particularly associated with marginal zone lymphoma (OR = 19.3; CI, 4.59-80.9). We found that time to relapse for all B-NHL patients with AIDs was significantly shorter (mean of 49.21 mo [+/-3.22]) than among patients without AID (mean of 59.74 mo [+/-1.62]), adjusted hazard ratio [HRadj ] = 1.69 (CI, 1.03 2.79). Specifically, in patients with diffuse large B-cell lymphoma, of whom 91.8% had received rituximab, a history of B-cell-mediated AIDs was associated with shorter relapse-free survival and overall survival, HRadj = 8.34 (CI, 3.01 23.1) and HRadj = 3.83 (CI, 1.20-12.3), respectively. Beyond confirming the well known association between AIDs and B-NHL, we found that AID is an adverse prognostic factor in B-cell lymphoma, associated with a shortened time to relapse, suggesting that there are specific therapeutic challenges in the subgroup of patients suffering from both these diseases. Further work is required to address mechanisms of resistance to standard treatment in the setting of AID associated B-NHL. In the era of immunotherapy, these findings have particular relevance. PMID- 29469177 TI - Haemodynamic effects of levosimendan in advanced but stable chronic heart failure. AB - AIMS: Levosimendan improves haemodynamics in acute decompensated heart failure (HF). However, it is increasingly used for repetitive or intermittent infusions in advanced but stable chronic HF, without clear indication, selection criteria, or effect. We tested the hypotheses that (1) levosimendan improves haemodynamics in stable chronic HF and (2) that the response is dependent on baseline clinical and haemodynamic factors. METHODS AND RESULTS: Twenty-three patients [median age 56 (49-64) years, four (17%) women] with stable New York Heart Association (NYHA) III and IV HF received a single 24 h levosimendan infusion. Non-invasive haemodynamics (inert gas re-breathing technique), estimated glomerular filtration rate, and N-terminal pro-brain natriuretic peptide were assessed before and after infusion. Levosimendan had the following effects (median change): a significant increase in cardiac output (+9.8 +/- 21.6%; P = 0.026) and decrease in N-terminal pro-brain natriuretic peptide (-28.1 +/- 16.3%, P < 0.001), estimated total peripheral resistance (-16.9 +/- 18.3%, P = 0.005), and mean arterial pressure ( 5.9 +/- 8.2%, P = 0.007), but no change in estimated glomerular filtration rate (+0.89 +/- 14.0%, P = 0.955). There were no significant associations between baseline clinical and/or haemodynamic factors and the levosimendan effect on cardiac output. CONCLUSIONS: Levosimendan was associated with improved haemodynamics in patients with stable chronic HF, but we could not identify any predictors of the magnitude of haemodynamic response. PMID- 29469179 TI - Novel Peroxides as Promising Anticancer Agents with Unexpected Depressed Antimalarial Activity. AB - Twenty six peroxides belonging to bridged 1,2,4,5-tetraoxanes, bridged 1,2,4 trioxolanes (ozonides), and tricyclic monoperoxides were evaluated for their in vitro antimalarial activity against Plasmodium falciparum (3D7) and for their cytotoxic activities against immortalized human normal fibroblast (CCD19Lu), liver (LO2 ), and lung (BEAS-2B) cell lines as well as human liver (HepG2) and lung (A549) cancer-cell lines. Synthetic ozonides were shown to have the highest cytotoxicity on HepG2 (IC50 =0.19-0.59 MUm), and some of these compounds selectively targeted liver cancer (selectivity index values for compounds 13 a and 14 a are 20 and 28, respectively) at levels that, in some cases, were higher than those of paclitaxel, artemisinin, and artesunic acid. In contrast some ozonides showed only moderate antimalarial activity against the chloroquine sensitive 3D7 strain of P. falciparum (IC50 from 2.76 to 24.2 MUm; 12 b, IC50 =2.76 MUm; 13 a, IC50 =20.14 MUm; 14 a, IC50 =6.32 MUm). These results suggest that these derivatives have divergent mechanisms of action against cancer cells and malaria-infected cells. A cyclic voltammetry study of the peroxides was performed, but most of the compounds did not show direct correlation in oxidative capacity-activity. Our findings offer a new source of antimalarial and anticancer agents through structural modification of peroxide compounds. PMID- 29469180 TI - Hybrid Graphene-Polyoxometalates Nanofluids as Liquid Electrodes for Dual Energy Storage in Novel Flow Cells. AB - Solid Hybrid materials abound. But flowing versions of them are new actors in the materials science landscape and in particular for energy applications. This paper presents a new way to deliver nanostructured hybrid materials for energy storage, namely, in the form of nanofluids. We present here the first example of a hybrid electroactive nanofluid (HENFs) combining capacitive and faradaic energy storage mechanisms in a single fluid material. This liquid electrode is composed of reduced graphene oxide and polyoxometalates (rGO-POMs) forming a stable nanocomposite for electrochemical energy storage in novel Nanofluid Flow Cells. Two graphene based hybrid materials (rGO-phosphomolybdate, rGO-PMo12 and rGO phosphotungstate, rGO-PW12 ) were synthesized and dispersed with the aid of a surfactant in 1 M H2 SO4 aqueous electrolyte to yield highly stable hybrid electroactive nanofluids (HENFs) of low viscosity which were tested in a home made flow cell under static and continuous flowing conditions. Remarkably, even low concentration rGO-POMs HENFs (0.025 wt%) exhibited high specific capacitances of 273 F/g(rGO-PW12 ) and 305 F/g(rGO-PMo12 ) with high specific energy and specific power. Moreover, rGO-POM HENFs show excellent cycling stability (~95 %) as well as Coulombic efficiency (~77-79 %) after 2000 cycles. Thus, rGO-POM HENFs effectively behave as real liquid electrodes with excellent properties, demonstrating the possible future application of HENFs for dual energy storage in a new generation of Nanofluid Flow Cells. PMID- 29469181 TI - Lymphocyte immunotherapy for recurrent miscarriages: Predictors of therapeutic success. AB - PROBLEM: To evaluate the predictors of successful pregnancies in women with a history of recurrent miscarriages (RMs) having undergone lymphocyte immunotherapy (LIT). METHOD OF STUDY: Retrospective, multicenter, observational study which involved 702 pregnant women with history of RM treated with LIT. Comparative analysis of women with a history of RM having undergone LIT and experienced treatment success vs those having experienced treatment failure along with the analysis of the association between the number of prior miscarriages and the efficacy of LIT. RESULTS: A total of 421 women were able to carry the pregnancy to term, with treatment success rate of 60%. The multivariate analysis showed that age, the association between autoantibodies and thrombophilia, and the number of previous miscarriages were factors associated with LIT failure. Secondary RMs alone were not found to be a factor predictive of LIT success or failure; however, secondary RMs among women with a history of 5 or more RM were found to be a predictor of LIT success (OR: 10.24; 95% CI: 1.9-55.8; P = .007). CONCLUSION: Age, the number of previous miscarriages, and the association between autoantibodies and thrombophilia are associated with LIT failure. A higher number of previous miscarriages in cases of secondary RM resulted in better LIT outcomes.

PMID- 29469183 TI - The [2+2] Cycloaddition-Retroelectrocyclization (CA-RE) Click Reaction: Facile Access to Molecular and Polymeric Push-Pull Chromophores. AB - The [2+2] cycloaddition-retroelectrocyclization (CA-RE) reaction between electron rich alkynes and electron-deficient alkenes is an efficient procedure to create nonplanar donor-acceptor (D-A) chromophores in both molecular and polymeric platforms. They feature attractive properties including intramolecular charge transfer (ICT) bands, nonlinear optical properties, and redox activities for use in next-generation electronic and optoelectronic devices. This Review summarizes the development of the CA-RE reaction, starting from the initial reports with organometallic compounds to the extension to purely organic systems. The structural requirements for rapid, high-yielding transformations with true click chemistry character are illustrated by examples that include the broad alkyne and alkene substitution modes. The CA-RE click reaction has been successfully applied to polymer synthesis, with the resulting polymeric push-pull chromophores finding many interesting applications. PMID- 29469184 TI - Low molecular weight heparin does not increase bleeding and mortality post endoscopic variceal band ligation in cirrhotic patients. AB - BACKGROUND & AIMS: Anticoagulants are commonly indicated in cirrhotic patients due to high rate of (pro)thrombotic conditions. Low molecular weight heparin (LMWH) is safe in patients with esophageal varices. However, the safety of LMWH is unknown in patients undergoing prophylactic endoscopic variceal ligation (EVL). To define the 4-week risk of bleeding and death after prophylactic EVL in cirrhotic patients continuously treated with LMWH. METHODS: All EVLs performed at a tertiary Italian Center from 2009 to 2016 were retrospectively reviewed. Patients treated with LMWH were classified as on-LMWH; the remaining as no-LMWH. Endoscopic characteristics at first and index EVL (that preceding an endoscopy either showing a bleeding episode or the absence of further treatable varices) and clinical events within 4 weeks from the procedures were recorded. RESULTS AND CONCLUSIONS: Five hundred fifty-three EVLs were performed in 265 patients (in 215 as a primary prophylaxis): 169 EVLs in 80 on-LMWH and 384 in 185 no-LMWH (4.9 +/- 1.1 vs 4.8 +/- 1.0 bands/session, respectively; P = .796). Six patients bled (2.2%) without between-groups difference (3.8% on-LMWH vs 1.6% no-LMWH, Log-rank P = .291). Large varices with red marks (100% vs 51.4%, P = .032), number of bands (5.6 +/- 0.5 vs 4.6 +/- 1.2, P = .004), underlying portal vein thrombosis (66.7% vs 23.6%, P = .033), and creatinine (2.2 +/- 2.7 vs 1.0 +/- 0.8 mg/dL, P = .001) at index EVL were significantly different between bleeders and non bleeders. Six patients died within 4-week from index EVL, without between-groups difference (2.5% on-LMWH vs 2.2% no-LMWH, Log-rank P = .863). LMWH does not increase the risk of post-procedural bleeding and does not affect survival of cirrhotic patients undergoing prophylactic EVL.

PMID- 29469187 TI - The prediction of cyclic proximal humerus fracture fixation failure by various bone density measures. AB - Fixation of osteoporotic proximal humerus fractures has remained challenging, but may be improved by careful pre-operative planning. The aim of this study was to investigate how well the failure of locking plate fixation of osteoporotic proximal humerus fractures can be predicted by bone density measures assessed with currently available clinical imaging (realistic case) and a higher resolution and quality modality (theoretical best-case). Various density measures were correlated to experimentally assessed number of cycles to construct failure of plated unstable low-density proximal humerus fractures (N = 18). The influence of density evaluation technique was investigated by comparing local (peri implant) versus global evaluation regions; HR-pQCT-based versus clinical QCT based image data; ipsilateral versus contralateral side; and bone mineral content (BMC) versus bone mineral density (BMD). All investigated density measures were significantly correlated with the experimental cycles to failure. The best performing clinically feasible parameter was the QCT-based BMC of the contralateral articular cap region, providing significantly better correlation (R2 = 0.53) compared to a previously proposed clinical density measure (R2 = 0.30). BMC had consistently, but not significantly stronger correlations with failure than BMD. The overall best results were obtained with the ipsilateral HR pQCT-based local BMC (R2 = 0.74) that may be used for implant optimization. Strong correlations were found between the corresponding density measures of the two CT image sources, as well as between the two sides. Future studies should investigate if BMC of the contralateral articular cap region could provide improved prediction of clinical fixation failure compared to previously proposed measures.

AB - BACKGROUND: Brain-derived neurotrophic factor (BDNF) is a neurotrophin that has a protective role in the nervous system and is involved in neural plasticity. It is abundant in the central nervous system, but is also expressed in the gastrointestinal tract. Coeliac disease (CD), characterised by intestinal inflammation, has some comorbidity with neurologic and mental disorders. The aim of this study was to evaluate circulating BDNF concentrations in patients with CD at diagnosis or on a gluten-free diet (GFD) for longer than 1 year and in healthy controls (HC). MATERIALS AND METHODS: Fifty newly diagnosed patients with CD (aged 8.6 +/- 3.7 years, 64.0% females), thirty-nine patients on GFD for longer than 1 year (aged 10.4 +/- 3.4 years, 71.8% females) and 36 HC (aged 8 +/- 1.7 years, 33.3% females) were included in the study. Along with anthropometric evaluation and standard blood chemistry, serum BDNF levels were measured by a specific immunoenzymatic assay. RESULTS: Patients at diagnosis and on GFD had significantly higher BDNF levels (26 110 +/- 8204 and 28 860 +/- 7992 pg/mL), respectively, than HC (19 630 +/- 8093 pg/mL, P < .001 for both CD groups). Patients on GFD had significantly higher BDNF levels than those at diagnosis (P = .02). CONCLUSIONS: Serum BDNF concentrations were higher in patients with CD than in HC, regardless of their status of gluten consumption. This could be attributed either to a potential protective response to the inflammation of the intestine or to chronic stress. PMID- 29469188 TI - Indeterminate cell histiocytosis in a Chinese patient with progressive and extensive nodular lesions and mixed indeterminate cell and macrophage-monocyte lineage. AB - Indeterminate cell histiocytosis (ICH) is an extremely rare cutaneous neoplastic disorder. It has the immunophenotypic features of both Langerhans and non Langerhans cell histiocytosis. We report here a case of a healthy young Chinese woman who presented with disfiguring, thick, infiltrated cutaneous nodules on the face, trunk and extremities which appeared progressively over a period of 4 years. No systemic involvement has been detected so far. Results of a skin biopsy showed diffuse dermal infiltration of histiocytoid cells with indented nuclei and positive staining for S100 and CD1a and negativity for CD207 (langerin). Admixed within were some CD68-positive foamy histiocytes and multinucleated giant cells with focal expression of CD163. Although the clinical presentation is more typical of progressive nodular histiocytosis, the histology and immunoprofile is consistent with ICH. Our report adds to the limited case reports in the current literature of ICH in the Chinese population. PMID- 29469190 TI - Prognostic significance of platelet-to-lymphocyte ratio in patients with ovarian cancer: A meta-analysis. AB - BACKGROUND: The platelet-to-lymphocyte ratio (PLR) has been found to predict clinical outcomes in borderline ovarian tumours and the other genital neoplasms. However, its prognostic value in patients with ovarian cancer remains controversial. The aim of this study was to assess its prognostic value in ovarian cancer. METHODS: We searched MEDLINE, EMBASE and the Cochrane databases to identify studies evaluating the prognostic significance of pretreatment PLR in ovarian cancer. The end points were overall survival (OS) and progression-free survival (PFS). Pooled hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated using fixed-effects/random-effects models. RESULTS: A total of 11 studies comprising 3574 patients with ovarian cancer were included. The random effects meta-analysis demonstrated that patients with elevated PLR had shorter OS (HR: 1.48, 95% CI: 1.24-1.76, P < .001) and PFS (HR: 1.38, 95% CI: 1.17-1.63, P < .001). The negative prognostic impact of high PLR on OS and PFS remained substantial in Asian populations, patients with PLR >= 200 and studies with NOS score >= 7. CONCLUSIONS: Elevated pretreatment PLR could be an unfavourable prognostic factor for clinical outcomes in patients with ovarian cancer. PMID- 29469189 TI - Incorporation of GSTA1 genetic variations into a population pharmacokinetic model for IV busulfan in paediatric hematopoietic stem cell transplantation. AB - AIMS: The aim of this study is to develop a population pharmacokinetic (PopPK) model for intravenous busulfan in children that incorporates variants of GSTA1, gene coding for the main enzyme in busulfan metabolism. METHODS: Busulfan concentration-time data was collected from 112 children and adolescents (median 5.4 years old, range: 0.1-20) who received intravenous busulfan during the conditioning regimen prior to stem cell transplantation. Weight, sex, baseline disease (malignant vs. non-malignant), age, conditioning regimen and GSTA1 diplotypes were evaluated as covariates of pharmacokinetic parameters by using nonlinear mixed effects analysis. The ability to achieve the target AUC24h (3600 6000 MUM min-1 ) was assessed by estimating the first dose based on the present PopPK model and by comparing the results with other available models in children. RESULTS: A one-compartment model with first-order elimination best described the data. Allometric scaling of weight and a factor of busulfan metabolism maturation were included in the base model. GSTA1 diplotypes were found to be a significant covariate of busulfan clearance, which was 7% faster in rapid metabolizers and 12% slower in poor metabolizers, in comparison with normal ones. Busulfan doses calculated using the parameters of the proposed PopPK model were estimated to achieve the target AUC in 85.2% of the cases (95% CI 78.7-91.7%). CONCLUSION: This is the first PopPK for busulfan that successfully incorporated GSTA1 genotype in a paediatric population. Its use may contribute to better prediction of busulfan exposure in children and adolescents since the first dose, by tailoring the dose according to the individual metabolic capacity.

PMID- 29469192 TI - GATA6-positive lung adenocarcinomas are associated with invasive mucinous adenocarcinoma morphology, hepatocyte nuclear factor 4alpha expression, and KRAS mutations. AB - AIMS: GATA6 is known to play a role in lung development. However, its role in the carcinogenesis of lung cancer is not well studied. The aim of this study was to analyse GATA6 expression in lung adenocarcinomas (LAs) by immunohistochemistry (IHC) in order to define its association with clinicopathological characteristics. METHODS AND RESULTS: IHC analysis of GATA6 was performed with tissue microarray slides containing 348 LAs. The association between GATA6 expression and clinicopathological parameters was evaluated. GATA6 expression in epithelial tumours other than lung cancer was also evaluated. GATA6 expression was found in 47 LAs (13.5%). This occurred more frequently in younger patients (P = 0.005), and was associated with the absence of lymph node metastasis (P =0.024), well-differentiated to moderately differentiated tumours (P < 0.001), the absence of lymphatic invasion (P = 0.020), and the absence of vascular invasion (P = 0.011). GATA6 expression was associated with mucin production (P < 0.001), the invasive mucinous adenocarcinoma subtype (P < 0.001), KRAS mutations (P = 0.026), expression of MUC2 (P < 0.001), CDX2 (P = 0.049), and MUC5AC (P < 0.001), and absence of expression of TTF-1 (P = 0.002). GATA6 expression was also associated with hepatocyte nuclear factor 4alpha (HNF4alpha) expression (P < 0.001). GATA6 expression tended to indicate better prognoses, whereas patients with HNF4alpha expression had significantly worse prognoses (P = 0.033). Of 270 tumours other than lung cancer, 110 expressed GATA6. CONCLUSIONS: These findings suggest that GATA6 might interact with HNF4alpha and contribute to the development of mucinous-type LAs. PMID- 29469194 TI - "Existential Fridays"-reflection in action. PMID- 29469195 TI - Postoperative ileus following major colorectal surgery. AB - BACKGROUND: Postoperative ileus (POI) is characterized by delayed gastrointestinal recovery following surgery. Current knowledge of pathophysiology, clinical interventions and methodological challenges was reviewed to inform modern practice and future research. METHODS: A systematic search of MEDLINE and Embase databases was performed using search terms related to ileus and colorectal surgery. All RCTs involving an intervention to prevent or reduce POI published between 1990 and 2016 were identified. Grey literature, non full-text manuscripts, and reanalyses of previous RCTs were excluded. Eligible articles were assessed using the Cochrane tool for assessing risk of bias. RESULTS: Of 5614 studies screened, 86 eligible articles describing 88 RCTs were identified. Current knowledge of pathophysiology acknowledges neurogenic, inflammatory and pharmacological mechanisms, but much of the evidence arises from animal studies. The most common interventions tested were chewing gum (11 trials) and early enteral feeding (11), which are safe but of unclear benefit for actively reducing POI. Others, including thoracic epidural analgesia (8), systemic lidocaine (8) and peripheral MU antagonists (5), show benefit but require further investigation for safety and cost-effectiveness. CONCLUSION: POI is a common condition with no established definition, aetiology or treatment. According to current literature, minimally invasive surgery, protocol-driven recovery (including early feeding and opioid avoidance strategies) and measures to avoid major inflammatory events (such as anastomotic leak) offer the best chances of reducing POI.

AB - The Global Horizon Scanning Project (GHSP) is an innovative initiative that aims to identify important global environmental quality research needs. Here we report 20 key research questions from Latin America (LA). Members of the Society of Environmental Toxicology and Chemistry (SETAC) LA and other scientists from LA were asked to submit research questions that would represent priority needs to address in the region. One hundred questions were received, then partitioned among categories, examined, and some rearranged during a workshop in Buenos Aires, Argentina. Twenty priority research questions were subsequently identified. These research questions included developing, improving, and harmonizing across LA countries methods for 1) identifying contaminants and degradation products in complex matrices (including biota); 2) advancing prediction of contaminant risks and effects in ecosystems, addressing lab-to field extrapolation challenges, and understanding complexities of multiple stressors (including chemicals and climate change); and 3) improving management and regulatory tools toward achieving sustainable development. Whereas environmental contaminants frequently identified in these key questions were pesticides, pharmaceuticals, endocrine disruptors or modulators, plastics, and nanomaterials, commonly identified environmental challenges were related to agriculture, urban effluents, solid wastes, pulp and paper mills, and natural extraction activities. Several interesting research topics included assessing and preventing pollution impacts on conservation protected areas, integrating environment and health assessments, and developing strategies for identification, substitution, and design of less hazardous chemicals (e.g., green chemistry). Finally, a recurrent research need included developing an understanding of differential sensitivity of regional species and ecosystems to environmental contaminants and other stressors. Addressing these critical questions will support development of long-term strategic research efforts to advance more sustainable environmental quality and protect public health and the environment in LA.

PMID- 29469196 TI - The relationship between inflammation and remodeling in childhood asthma: A systematic review. AB - OBJECTIVES: We aimed to perform a systematic review of all studies with direct measurements of both airway inflammation and remodeling in the subgroup of children with repeated wheezing and/or persistent asthma severe enough to warrant bronchoscopy, to address whether airway inflammation precedes remodeling or is a parallel process, and also to assess the impact of remodeling on lung function. METHODS: Four databases were searched up to June 2017. Two independent reviewers screened the literature and extracted relevant data. RESULTS: We found 526 references, and 39 studies (2390 children under 18 years old) were included. Airway inflammation (eosinophilic/neutrophilic) and remodeling were not present in wheezers at a mean age of 12 months, but in older pre-school children (mean 2.5 years), remodeling (mainly increased reticular basement membrane [RBM] thickness and increased area of airway smooth muscle) and also airway eosinophilia was reported. This was worse in school-age children. RBM thickness was similar in atopic and non-atopic preschool wheezers. Airway remodeling was correlated with lung function in seven studies, with FeNO in three, and with HRCT scan in one. Eosinophilic inflammation was not seen in patients without remodeling. There were no invasive longitudinal or intervention studies. CONCLUSION: The relationship between inflammation and remodeling in children cannot be determined. Failure to demonstrate eosinophilic inflammation in the absence of remodeling is contrary to the hypothesis that inflammation causes these changes. We need reliable, non-invasive markers of remodeling in particular if this is to be addressed. PMID- 29469197 TI - Physiologically-based pharmacokinetic modelling of a CYP2C19 substrate, BMS 823778, utilizing pharmacogenetic data. AB - AIMS: Previous studies demonstrated direct correlation between CYP2C19 genotype and BMS-823778 clearance in healthy volunteers. The objective of the present study was to develop a physiologically-based pharmacokinetic (PBPK) model for BMS 823778 and use the model to predict PK and drug-drug interaction (DDI) in virtual populations with multiple polymorphic genes. METHODS: The PBPK model was built and verified using existing clinical data. The verified model was simulated to predict PK of BMS-823778 and significance of DDI with a strong CYP3A4 inhibitor in subjects with various CYP2C19 and UGT1A4 genotypes. RESULTS: The verified PBPK model of BMS-823778 accurately recovered observed PK in different populations. In addition, the model was able to capture the exposure differences between subjects with different CYP2C19 genotypes. PK simulation indicated higher exposures of BMS 823778 in CYP2C19 poor metabolizers who were also devoid of UGT1A4 activity, compared to those with normal UGT1A4 functionality. Moderate DDI with itraconazole was predicted in subjects with wild-type CYP2C19 or UGT1A4. However, in subjects without CYP2C19 or UGT1A4 functionality, significant DDI was predicted when BMS-823778 was coadministered with itraconazole. CONCLUSIONS: A PBPK model was developed using clinical data that accurately predicted human PK in different population with various CYP2C19 phenotypes. Simulations with the verified PBPK model indicated that UGT1A4 was probably an important clearance pathway in CYP2C19 poor metabolizers. DDI with itraconazole is likely to be dependent on the genotypes of CYP2C19 and UGT1A4. PMID- 29469198 TI - Dose-escalation is needed for gross disease in high-risk neuroblastoma. AB - BACKGROUND: Locoregional failure is common after subtotal resection in high-risk neuroblastoma. Although a dose of 21 Gy radiation therapy (RT) is standard for treatment of high-risk neuroblastoma after gross total resection, the dose needed for local control of patients with gross residual disease at the time of RT is unknown. We sought to evaluate local control after 21-36 Gy RT in patients with high-risk neuroblastoma undergoing subtotal resection. METHODS: All patients with high-risk neuroblastoma who received RT to their primary site from 2000 to 2016 were reviewed. Of the 331 patients who received consolidative RT to their primary site, 19 (5.7%) underwent subtotal resection and were included in our analysis. Local failure (LF) was correlated with biologic prognostic factors and dose of RT. RESULTS: Median follow-up among surviving patients was 6.0 years. Median RT dose was 25 Gy (range, 21 Gy-36 Gy). The 5-year cumulative incidence of LF among all patients was 17.2%. LF at 5 years was 30% in those who received <30 Gy versus 0% in those who received 30-36 Gy (P = 0.12). There was a trend towards improved local control in patients with tumor size <=10 cm at diagnosis (P = 0.12). The 5 year event-free and overall survival were 44.9% and 68.7%, respectively. CONCLUSION: After subtotal resection, patients who received less than 30 Gy had poor local control. Doses of 30-36 Gy are likely needed for optimal control of gross residual disease at the time of consolidative RT in high-risk neuroblastoma. PMID- 29469199 TI - Elucidation of the origin of 'agriocrithon' based on domestication genes questions the hypothesis that Tibet is one of the centers of barley domestication. AB - Wild barley forms a two-rowed spike with a brittle rachis whereas domesticated barley has two- or six-rowed spikes with a tough rachis. Like domesticated barley, 'agriocrithon' forms a six-rowed spike; however, the spike is brittle as in wild barley, which makes the origin of agriocrithon obscure. Haplotype analysis of the Six-rowed spike 1 (vrs1) and Non-brittle rachis 1 (btr1) and 2 (btr2) genes was conducted to infer the origin of agriocrithon barley. Some agriocrithon barley accessions (eu-agriocrithon) carried Btr1 and Btr2 haplotypes that are not found in any cultivars, implying that they are directly derived from wild barley through a mutation at the vrs1 locus. Other agriocrithon barley accessions (pseudo-agriocrithon) carried Btr1 or Btr2 from cultivated barley, thus implying that they originated from hybridization between six-rowed landraces carrying btr1Btr2 and Btr1btr2 genotypes followed by recombination to produce Btr1Btr2. All materials we collected from Tibet belong to pseudo-agriocrithon and thus do not support the Tibetan Plateau as being a center of barley domestication. Tracing the evolutionary history of these allelic variants revealed that eu-agriocrithon represents six-rowed barley lineages that were selected by early farmers, once in south-eastern Turkmenistan (vrs1.a1) and again in the eastern part of Uzbekistan (vrs1.a4). PMID- 29469200 TI - Mutiple DICER1-related lesions associated with a germline deep intronic mutation. AB - Germline DICER1 pathogenic variants predispose to numerous benign and malignant tumors. In this report, we describe DICER1 gene analysis in an adolescent diagnosed with multinodular goiter, ovarian Sertoli-Leydig cell tumor, and lung cyst. DICER1 mutational screening at the DNA level failed to detect any pathogenic variant. Subsequent messenger RNA (mRNA) analysis revealed a 132 nucleotide intronic sequence exonization. This truncating event was caused by a deep intronic mutation generating a de novo acceptor splice site. This study demonstrates that some undetected DICER1 mutations should be investigated at the mRNA level. PMID- 29469201 TI - Dynamics of Mechanosensitive Neural Stem Cell Differentiation.

Case of a preterm newborn who presented a bilateral thrombosis of the pulmonary arteries associated with a congenital nephrotic syndrome. Pediatricians should consider pulmonary thromboembolic episodes in cases of newborns with unexplained severe and hypoxic respiratory distress syndrome. PMID- 29469203 TI - Coupling imaged capillary isoelectric focusing with mass spectrometry using a nanoliter valve. AB - Imaged capillary isoelectric focusing (iCIEF) is a powerful separation technique applied frequently for the analysis of biotherapeutics. However, direct mass spectrometric characterization is usually not possible. Here, focused peaks from an iCIEF system are transferred to a four-port nanoliter valve where peaks of interest are cut and transferred directly (flow injection) or via capillary zone electrophoresis to electrospray mass spectrometry. At first, flow injection coupling was tested with a mixture of peptides showing intraday precision (RSD) of 20.0 and 3.4% in area and 15.2 and 6.3% in intensity for angiotensin I and leucine-enkephalin, respectively. For the analysis of charge variants in an intact mAb, flow injection and CZE as second dimension were compared, demonstrating the usability of flow injection even for large proteins. However, improved spectra quality was achieved when CZE-MS was applied. In this way, accurate masses were obtained not only for the main isoform, but also for the main acidic and basic variants. These results demonstrate the power of iCIEF-CZE MS for the analysis of biotherapeutics. PMID- 29469204 TI - Plasma ammonia concentration after L-asparaginase therapy in 27 dogs with high grade lymphoma or leukemia. AB - OBJECTIVES: To establish the occurrence of increased plasma ammonia concentration after L-asparaginase (L-asp) administration in dogs with high-grade lymphoma or leukemia; to identify risk factors for the development of hyperammonemia after L asp administration; and to determine occurrence of adverse events related to hyperammonemia. DESIGN: Prospective case controlled study of sequentially enrolled dogs between May 2011 and March 2012. SETTING: A university veterinary teaching hospital. ANIMALS: Twenty-seven dogs with high-grade lymphoma or leukemia. INTERVENTIONS: All dogs received L-asp intramuscularly at a median dose of 400 IU/kg. MEASUREMENTS AND MAIN RESULTS: Plasma ammonia concentrations were measured at baseline, 16 hours, and 48 hours after L-asp therapy. Clinicopathological abnormalities were assessed to determine risk factors for the development of hyperammonemia. Adverse events following L-asp were recorded. Median plasma ammonia concentrations at baseline, 16 hours, and 48 hours were 26 MUmol/L (44 MUg/dL), 98 MUmol/L (166.9 MUg/dL), and 67 MUmol/L (114 MUg/dL), respectively. Median plasma ammonia concentrations at 16 and 48 hours after administration were significantly increased compared to baseline. Six dogs had adverse events following L-asp administration. No significant clinical signs were noted that could clearly be attributed to hyperammonemia. No risk factors for developing hyperammonemia were identified; however, there was a positive correlation between the development of hyperammonemia at 16- and 48-hour time points. CONCLUSIONS: Subclinical hyperammonemia in dogs with lymphoma or leukemia after L-asp administration appears to be common. No risk factors were identified for the development of hyperammonemia after L-asp treatment, and severe adverse events were rare. PMID- 29469205 TI - The diagnostic value of cell blocks in Liquid-Based Cytology of bronchial aspiration and bronchial brushing materials. AB - INTRODUCTION: Fibreoptic bronchoscopy is used for the diagnosis and treatment of several pulmonary diseases. Conventional smear and Liquid-based cytology (LBC) methods are applied to cytology samples of various bronchoscopic techniques. If the cytology sample is sufficient for evaluation, a cell block (CB) can be prepared from the remaining material. The aim of this study is to identify the diagnostic value of conventional smear, LBC and CB methods in bronchial cytological specimens. METHODS: A retrospective review of 329 samples from 240 patients was made and, of these, 144 patients were found to have neoplasia. A blind review of the specimens was performed and all were reclassified individually. The endoscopic findings of the 144 patients with neoplasia were analysed retrospectively. The cytological diagnoses were then compared with the final diagnosis or the endoscopic findings of patients with neoplasia. The sensitivity was calculated for each method, both separately and together. RESULTS: It was determined that CB led to a 10.1% increase in the diagnostic sensitivity for bronchial aspiration (BA) specimens, while no significant increase was seen in bronchial brush specimens. In BA specimens of neoplasia patients with normal bronchoscopic findings, while three methods were applied together with an increase in the number of cases diagnosed as malignant cytology, there was no significant increase in bronchial brush specimens. CONCLUSION: This study demonstrated that adding cell block to CB and LBC seemed to contribute the cytological diagnosis in BA materials significantly. Another advantage of CB is the opportunity of applying advanced methods such as immunocytochemical and molecular techniques. PMID- 29469206 TI - Impact of sacubitril-valsartan combination in patients with chronic heart failure and sleep apnoea syndrome: the ENTRESTO-SAS study design. AB - AIMS: Sleep-disordered breathing (SDB) is a highly prevalent co-morbidity in patients with chronic heart failure (CHF) and can play a detrimental role in the pathophysiology course of CHF. However, the best way to manage SDB in CHF remains a matter of debate. Sacubitril-valsartan has been included in the 2016 European Society of Cardiology guidelines as an alternative to angiotensin-converting enzyme inhibitors to further reduce the risk of progression of CHF, CHF hospitalization, and death in ambulatory patients. Sacubitril and valsartan are good candidates for correcting SDB of CHF patients because their known mechanisms of action are likely to counteract the pathophysiology of SDB in CHF. METHODS AND RESULTS: The ENTRESTO-SAS trial is a 3-month, multicentric, prospective, open label real-life cohort study. Patients eligible for sacubitril-valsartan treatment (i.e. adults with left ventricular ejection fraction <=35%, who remain symptomatic despite optimal treatment with an angiotensin-converting enzyme inhibitor, a beta-blocker, and a mineralocorticoid receptor antagonist) will be evaluated before and after 3 months of treatment (nocturnal ventilatory polygraphy, echocardiography, laboratory testing, and quality-of-life and SDB questionnaires). The primary outcome is the change in the Apnoea-Hypopnoea Index, before and after 3 months of treatment. One hundred twenty patients are required to detect a significant 20% improvement of the Apnoea-Hypopnoea Index with a power of 90% at an alpha risk of 5%. CONCLUSIONS: In the context of the SERVE-HF study, physicians are waiting for new trials and alternative therapies. We sought to assess in the ENTRESTO-SAS trial whether sacubitril-valsartan could improve the outcome of SDB in CHF patients. PMID- 29469207 TI - Evaluation of contrasting techniques for X-ray imaging of velvet worms (Onychophora). AB - Non-invasive imaging techniques like X-ray computed tomography have become very popular in zoology, as they allow for simultaneous imaging of the internal and external morphology of organisms. Nevertheless, the effect of different staining approaches required for this method on samples lacking mineralized tissues, such as soft-bodied invertebrates, remains understudied. Herein, we used synchrotron radiation-based X-ray micro-computed tomography to compare the effects of commonly used contrasting approaches on onychophorans - soft-bodied invertebrates important for studying animal evolution. Representatives of Euperipatoides rowelli were stained with osmium tetroxide (vapour or solution), ruthenium red, phosphotungstic acid, or iodine. Unstained specimens were imaged using both standard attenuation-based and differential phase-contrast setups to simulate analyses with museum material. Our comparative qualitative analyses of several tissue types demonstrate that osmium tetroxide provides the best overall tissue contrast in onychophorans, whereas the remaining staining agents rather favour the visualisation of specific tissues and/or structures. Quantitative analyses using signal-to-noise ratio measurements show that the level of image noise may vary according to the staining agent and scanning medium selected. Furthermore, box-and-whisker plots revealed substantial overlap in grey values among structures in all datasets, suggesting that a combination of semiautomatic and manual segmentation of structures is required for comprehensive 3D reconstructions of Onychophora, irrespective of the approach selected. Our results show that X-ray micro-computed tomography is a promising technique for studying onychophorans and, despite the benefits and disadvantages of different staining agents for specific tissues/structures, this method retrieves informative data that may eventually help address evolutionary questions long associated with Onychophora. PMID- 29469208 TI - Molecular characterization and multidisciplinary management of Gerbich hemolytic disease of the newborn. AB - Gerbich (Ge) antigens are high frequency red cell antigens expressed on glycophorin C (GYPC) and glycophorin D. Hemolytic disease of the fetus and newborn (HDFN) due to Gerbich antibody is rare and presents a clinical challenge, as Gerbich negative blood is scarce. We report a case of HDFN due to maternal Ge3 negative phenotype and anti-Ge3 alloimmunization, successfully managed by transfusion of maternal blood. Molecular testing revealed that the mother has homozygous deletion of exon 3 of GYPC, the father is homozygous wildtype for GYPC, and the infant is obligate heterozygote expressing Ge3. PMID- 29469209 TI - The impact of aging on different types of health care: The example of the Polish health insurance system. AB - The aging phenomenon, which is being observed all over the world, can strongly affect health policy and a planning in the health care sector. However, the impact of demographic changes on different parts of it can be varied. The main objective of this study was to check the possible impact of aging on health expenditure (HE) regarding different types of health care and to evaluate whether this impact is significant for all analyzed areas. To show a relationship between age and HE a special indicator (old-age sensitivity) was defined, showing a difference between the standardized value of HE per capita in the age group 65+ and in the group 20 to 64 (defined as the reference group). Then a simple prognosis of expenditure was prepared. Both analyses were done separately for 11 types of health care services and 2 types of goods reimbursement. The results show that while sensitivity varies between the different types of care, however, it is strong in most of them. Because of the prognosis, the expenditure will be increasing for the 9 types of care and decreasing for 4 of them. While in the case of the low values of sensitivity the HE is actually decreasing, the high value of sensitivity does not result in a growing tendency. Our main conclusion is that it is very important for health policy and planning to take into account the diversity of the types of health care and the different influences of changes in the size and structure of population on them.

PMID- 29469212 TI - Administrative reform and pay-for-performance methods of primary health service delivery: A comparison of 3 health districts in Cambodia, 2006-2012. AB - Since 1999, performance-based financing or pay-for-performance (P4P) methods have been piloted in the Cambodian public health sector, first as one part of external contracting approaches with international nongovernment organizations and from 2009 as a part of internal contracting arrangements between units within the Ministry of Health under a wider public sector administrative reform. This study analyses these reforms and compares outcomes in 3 health districts. The study analysed routine quantitative data for primary care service delivery by using the interrupted time series method. Qualitative data were collected from key informant interviews. Both the level and the trend line of key service delivery indicators during earlier contracting/P4P models were at least maintained and in most cases increased with the move to internal contracting. The results of the interrupted time series analysis were mixed, mainly due to contextual issues. Qualitative results indicated an increased sense of local ownership and financial sustainability. Despite the gains, the management of personnel and the implementation and the integrity of contract monitoring were found to be compromised in this case. To be fully effective, contracting and P4P approaches must be accompanied by changes in the structure and culture of government administration. PMID- 29469213 TI - Exosomes Enter Vaccine Development: Strategies Meeting Global Challenges of Emerging Infections. AB - New approaches for vaccination must be developed in order to meet the grand challenges for emerging infectious diseases. Exosomes now enter vaccine development and these are strategies are meeting these global challenges, as demonstrated by Anticoli et al., in this issue of Biotechnology Journal. Using exosome vaccines has been now been demonstrated in vivo for several viruses such as Ebola Virus VP24, VP40, and NP, Influenza Virus NP, Crimean-Congo Hemorrhagic Fever NP, West Nile Virus NS3, and Hepatitis C Virus NS3. Now this technology must be tested in clinics. PMID- 29469214 TI - FOOD NEGLECT AND INFANT DEVELOPMENT. AB - The impact of food insecurity on child development in the general U.S. population is well-established, yet little is known about the harm of food neglect relative to other types of maltreatment. Due to the harmful physiological impact of inadequate nutrients and the social impact of food-related stress, it was hypothesized that food neglect would be more likely to impair infant cognitive and language development than physical abuse, sexual abuse, and other forms of neglect. Families of infants (N = 1,951) investigated by Child Protective Services were studied using the second cohort of the National Survey of Child and Adolescent Well-Being (NSCAW II; NSCAW Research Group, 2002). Results from multivariable logistic regression models that controlled for likely confounding variables showed that the odds of impairment in cognition and language were significantly greater when food neglect was the most serious form of maltreatment. Considering that both food insecurity and child neglect are associated with poverty and parental mental health problems, it will be important for child welfare and mental health professionals to work collaboratively to better the health of these vulnerable children. PMID- 29469215 TI - Dinitrosyl iron complexes: Formation and antiradical action in heart mitochondria. AB - Mitochondria are widely known as a major source of reactive oxygen and nitrogen species for the cardiovascular system. Numerous studies established that superoxide anion radical production by heart mitochondria is only slightly suppressed under conditions of deep hypoxia, but is completely blocked under anoxia. It was found also that dinitrosyl iron complexes (DNIC) compare favourably with other physiologically active derivatives of nitric oxide (NO). DNIC with glutathione effectively scavenge superoxide radicals generated by mitochondria at different partial pressures of oxygen. Under conditions of simulated hypoxia, the synthesis of thiol-containing DNIC takes place in mitochondria and is concomitant with a significant decrease in the concentration of NO metabolites at the reoxygenation step. Free NO required for DNIC synthesis is generated in the reaction of S-nitrosothiols with superoxide or during single electron oxidation of the nitroxyl radical (HNO) by coenzyme Q. Plausible mechanisms of antiradical effects of DNIC and their protective role in oxidative stress induced by hypoxia/reoxygenation of myocardial tissues are considered.

AB - Total synthesis of (-)-enigmazole A, a marine macrolide natural product with cytotoxic activity, has been accomplished. The tetrahydropyran moiety was constructed by means of a domino olefin cross-metathesis/intramolecular oxa Michael addition of a delta-hydroxy olefin. After coupling of advanced intermediates, the macrocycle was formed through gold-catalyzed rearrangement of a propargylic benzoate, followed by ring-closing metathesis of the resultant alpha,beta-unsaturated ketone. PMID- 29469217 TI - Effect of treatment with direct acting antivirals on body mass index and hepatic steatosis in chronic hepatitis C. AB - Direct Acting Agents (DAAs) have high cure rate but still lack the knowledge of their effect on hepatic steatosis in chronic hepatitis C (CHC). Controlled Attenuation Parameter (CAP), evaluated with transient elastography, could help in assessment of steatosis grades. We aim to evaluate the effect of DAAs on BMI and steatosis in CHC using CAP. This cohort study included 155 CHC Egyptian patients divided into three groups according to the DAAs regimens. All patients were subjected to pre-treatment and 3-months post-treatment evaluation including BMI, laboratory workup and liver stiffness measurement with simultaneous CAP determination using the (FibroScan(r)) M probe. Patients mean age was 45.78 +/- 11.6 years, 60.6% were females, mean BMI 26.63 +/- 2.75 and 18.1% were cirrhotic. Baseline assessment revealed no steatosis in 43.9%, 32.9% had mild-moderate steatosis and 23.2% had severe steatosis. The overall sustained virological response 12 was 93.6%. Follow-up revealed stationary steatosis in 56.7% of patients and regression in 21.3%. Mean pre-treatment CAP were significantly lower in responders 244.9 +/- 62.4 dB/m versus non-responders; 300 +/-28.4 dB/m (P = 0.04). ROC curve delineated 273 dB/m as best cutoff for detection of responders with an AUC of 0.801, sensitivity 68.2%, and specificity 100%. BMI significantly increased after treatment (P = 0.004) particularly in patients with worsened steatosis (P = 0.001). Steatosis significantly correlated with BMI (r = 0.3, P value = < 0.001). DAAs causes a significant change in steatosis grade in a subset of treated patients. Pretreatment CAP was significantly lower in responders. BMI significantly increases following treatment particularly in patients with worsened steatosis. PMID- 29469218 TI - Highly Confined and Tunable Hyperbolic Phonon Polaritons in Van Der Waals Semiconducting Transition Metal Oxides. AB - 2D van der Waals (vdW) layered polar crystals sustaining phonon polaritons (PhPs) have opened up new avenues for fundamental research and optoelectronic applications in the mid-infrared to terahertz ranges. To date, 2D vdW crystals with PhPs are only experimentally demonstrated in hexagonal boron nitride (hBN) slabs. For optoelectronic and active photonic applications, semiconductors with tunable charges, finite conductivity, and moderate bandgaps are preferred. Here, PhPs are demonstrated with low loss and ultrahigh electromagnetic field confinements in semiconducting vdW alpha-MoO3 . The alpha-MoO3 supports strong hyperbolic PhPs in the mid-infrared range, with a damping rate as low as 0.08. The electromagnetic confinements can reach ~lambda0 /120, which can be tailored by altering the thicknesses of the alpha-MoO3 2D flakes. Furthermore, spatial control over the PhPs is achieved with a metal-ion-intercalation strategy. The results demonstrate alpha-MoO3 as a new platform for studying hyperbolic PhPs with tunability, which enable switchable mid-infrared nanophotonic devices. PMID- 29469219 TI - Erdheim-Chester disease: description of two illustrative cases involving the lung. AB - AIM: Erdheim-Chester disease represents a clonal systemic proliferation of histiocytes. Bone is the most common site of involvement, although almost any organ, including the lungs, can be affected. METHODS AND RESULTS: The diagnosis of Erdheim-Chester disease can be difficult, owing to its rarity and protean presentation. Correlation between clinical, radiological and histological findings is mandatory for identification of the disease. Foamy histiocytes, lacking Langerhans cell markers, represent the typical histological findings, although their absence does not rule out Erdheim-Chester disease. Identification of BRAF mutation can be helpful in making the diagnosis, and allows for the development and application of targeted therapies in this setting. CONCLUSIONS: Herein, we describe two cases presenting with lung involvement and vertebral lesions, lacking the more typical long-bone involvement. One case histologically mimicked Rosai-Dorfman disease. However, both cases harboured the pathognomonic BRAFV600E mutation. PMID- 29469220 TI - Mechanisms in Iodine Catalysis. AB - Molecular iodine has been used for more than 100 years as a remarkable catalyst for many organic transformations such as cycloadditions, Michael and aldol reactions, or esterifications. Different explanations for the origin of its catalytic effect have been proposed in the last decades including a "hidden" Bronsted acid catalysis by HI, a Lewis-acid (or halogen-bond) activation, or catalysis by an iodonium(I) species. Recently, iodine catalysis again gained more interest due to the latest developments in halogen-bond catalysis. In this Minireview, we first summarize the experimental basis for the proposed modes of activation. Subsequently, we analyze typical iodine-catalyzed reactions to gain more insights into the underlying reaction mechanisms. PMID- 29469221 TI - Molecular Recognition by a Short Partial Peptide of the Adrenergic Receptor: A Bottom-Up Approach. AB - Receptor-neurotransmitter molecular recognition is key for neurotransmission. Although crystal structures of the receptors are known, the mechanism for recognition is not clear. Reported here is the ultraviolet (UV) and infrared (IR) spectra of complexes between a partial peptide (SIVSF), mimicking the binding motif of a catechol ring in the adrenergic receptor, and various ligands. The UV spectra show that two isomers coexist in the complex of SIVSF with properly recognized ligands, such as protonated adrenaline (adrenalineH+ ). From IR spectra, they are assigned to catechol- and amino-bound structures. The catechol bound structure is not observed when the ligand is replaced by nonproper molecules, such as noradrenalineH+ . The results suggest that SIVSF not only recognizes the catechol ring but can distinguish differences in the amine side chain. The method provides a new possibility for screening molecules as potential therapeutics for activating the receptor. PMID- 29469224 TI - Anisotropic Colloids: From Non-Templated to Patchy Templated Synthesis. AB - Self-assembly of colloidal particles is an important and challenging way to generate novel colloidal superstructures for new materials. Recent progress on syntheses of anisotropic colloids highlights opportunities for such self assembly, particularly in defining new non-cubic superstructures. Both non templated and templated synthesis play an important role in preparing anisotropic colloidal particles. In this article, we briefly summarize recent progress in anisotropic colloids by non-templated and conventional templated synthesis, and introduce a conceptual strategy of "patchy templated synthesis" that differs from the conventional approach. We illustrate this strategy with recent examples emanating from colloidal rings, and discuss the future opportunities with this strategy for the synthesis of other anisotropic colloids. PMID- 29469223 TI - Mitoprotective therapy preserves chondrocyte viability and prevents cartilage degeneration in an ex vivo model of posttraumatic osteoarthritis. AB - : No disease-modifying osteoarthritis (OA) drugs are available to prevent posttraumatic osteoarthritis (PTOA). Mitochondria (MT) mediate the pathogenesis of many degenerative diseases, and recent evidence indicates that MT dysfunction is a peracute (within minutes to hours) response of cartilage to mechanical injury. The goal of this study was to investigate cardiolipin-targeted mitoprotection as a new strategy to prevent chondrocyte death and cartilage degeneration after injury. Cartilage was harvested from bovine knee joints and subjected to a single, rapid impact injury (24.0 +/-1.4 MPa, 53.8 +/- 5.3 GPa/s). Explants were then treated with a mitoprotective peptide, SS-31 (1uM), immediately post-impact, or at 1, 6, or 12 h after injury, and then cultured for up to 7 days. Chondrocyte viability and apoptosis were quantified in situ using confocal microscopy. Cell membrane damage (lactate dehydrogenase activity) and cartilage matrix degradation (glycosaminoglycan loss) were quantified in cartilage-conditioned media. SS-31 treatment at all time points after impact resulted in chondrocyte viability similar to that of un-injured controls. This effect was sustained for up to a week in culture. Further, SS-31 prevented impact induced chondrocyte apoptosis, cell membrane damage, and cartilage matrix degeneration. CLINICAL SIGNIFICANCE: This study is the first investigation of cardiolipin-targeted mitoprotective therapy in cartilage. These results suggest that even when treatment is delayed by up to 12 h after injury, mitoprotection may be a useful strategy in the prevention of PTOA. (c) 2018 Orthopaedic Research Society.

AB - Borrelia burgdorferi infection is common in horses living in Lyme endemic areas and the geographic range for exposure is increasing. Morbidity after B. burgdorferi infection in horses is unknown. Documented, naturally occurring syndromes attributed to B. burgdorferi infection in horses include neuroborreliosis, uveitis, and cutaneous pseudolymphoma. Although other clinical signs such as lameness and stiffness are reported in horses, these are often not well documented. Diagnosis of Lyme disease is based on exposure to B. burgdorferi, cytology or histopathology of infected fluid or tissue and antigen detection. Treatment of Lyme disease in horses is similar to treatment of humans or small animals but treatment success might not be the same because of species differences in antimicrobial bioavailability and duration of infection before initiation of treatment. There are no approved equine label Lyme vaccines but there is strong evidence that proper vaccination could prevent infection in horses.

AB - BACKGROUND: Infantile malignant osteopetrosis (IMO) is an autosomal recessive condition characterized by defective osteoclast activity, with hematopoietic bone marrow transplant being the only available cure. Over the past several years, new conditioning regimes and donor options have emerged, thus extending the possibility of cure to a greater number of patients and improving the outcomes of bone marrow transplant. Here we detail the outcomes of bone marrow transplant in a cohort of 31 patients treated with a combination of fludarabine, treosulphan, thiotepa, and antithymocyte globulin. PROCEDURES: Thirty-one patients with IMO who underwent hematopoietic stem cell transplantation with fludarabine, treosulphan, thiotepa, and antithymocyte globulin at our center from 2012 to 2017 are retrospectively reviewed in this study. Twenty-six patients were transplanted from 10/10 matched donors (13 from siblings, 11 from unrelated, and two from extended family donors), four from 9/10 matched unrelated donors, and one from a 9/10 matched family donor. RESULTS: Overall survival was 100% with a median follow-up of 363 days (range 74-1891). There were 12 cases of acute graft versus host disease (GvHD) (38.7%), no cases of veno-occlusive disease, and eight cases of hypercalcemia (25.8%). Almost 80% of patients suffered viral reactivations with two cases of Epstein-Barr-virus-driven post-transplant lymphoproliferative disease. All cases of GvHD and viral reactivation were successfully treated. CONCLUSIONS: We conclude that transplantation in children with IMO using fludarabine, treosulphan, thiotepa, and antithymocyte globulin is safe and effective and should be performed as early as possible following diagnosis, prior to the development of severe disease sequelae.

AB - Major disadvantages of black phosphorus (BP) are its poor air-stability and poor solubility in common organic solvents. The best way to solve this problem is to incorporate BP into a polymer backbone or a polymer matrix to form novel functional materials that can provide both challenges and opportunities for new innovation in optoelectronic and photonic applications. As a proof-of concept application, we synthesized in situ the first highly soluble conjugated polymer covalently functionalized BP derivative (PDDF-g-BP) which was used to fabricate a resistive random access memory (RRAM) device with a configuration of Au/PDDF-g BP/ITO. In contrast to PDDF without memory effect, PDDF-g-BP-based device exhibits a nonvolatile rewritable memory performance, with a turn-on and turn-off voltages of +1.95 V and -2.34 V, and an ON/OFF current ratio of 104 . The current through the device in both the ON and OFF states is still kept unchanged even at 200th switching cycle. The PDDF/BP blends show a very unstable memory performance with a very small ON/OFF current ratio.

AB - Beneficial fungal and rhizobial symbioses share commonalities in phytohormones responses, especially in auxin signalling. Mutualistic fungus Phomopsis liquidambari effectively increases symbiotic efficiency of legume peanut (Arachis hypogaea L.) with another microsymbiont, bradyrhizobium, but the underlying mechanisms are not well understood. We quantified and manipulated the IAA accumulation in ternary P. liquidambari-peanut-bradyrhizobial interactions to uncover its role between distinct symbioses. We found that auxin signalling is both locally and systemically induced by the colonization of P. liquidambari with peanut and further confirmed by Arabidopsis harbouring auxin-responsive reporter, DR5:GUS, and that auxin action, including auxin transport, is required to maintain fungal symbiotic behaviours and beneficial traits of plant during the symbiosis. Complementation and action inhibition experiments reveal that auxin signalling is involved in P. liquidambari-mediated nodule development and N2 fixation enhancement and symbiotic gene activation. Further analyses showed that blocking of auxin action compromised the P. liquidambari-induced nodule phenotype and physiology changes, including vascular bundle development, symbiosome and bacteroids density, and malate concentrations, while induced the accumulation of starch granules in P. liquidambari-inoculated nodules. Collectively, our study demonstrated that auxin signalling activated by P. liquidambari symbiosis is recruited by peanut for bradyrhizobial symbiosis via symbiotic signalling pathway activation and nodule carbon metabolism enhancement.

AB - The swim bladder of a fish is a vital organ that with gas gland cells in the swim bladder wall enables key physiological functions including buoyancy regulation in the face of different hydrostatic pressures. Specific gas gland cells produce and secrete acidic metabolites into the blood in order to reduce the physical solubility of gases and blood gas transport capacity for regulating the volume of the swim bladder. Transcriptomic analyses have provided evidence at the RNA level but no specific studies at the protein level have been carried out so far. Herein, it was the aim of the study to show swim bladder proteins of the yellow stage European eel by label-free LCMS (Q-Exactive Plus) that resulted in the identification of 6223 protein groups. Neurotransmitter receptors and transporters were enriched in the membrane fraction and enzymes for acid production were observed. The list of identified proteins may represent a useful tool for further proteomics experiments on this organ. All MS proteomics data are available at the PRIDE repository with the dataset identifier PXD007850.

AB - SCOPE: Diabetic nephropathy (DN) is a micro-vascular complication of chronic diabetes. Sterol regulatory element binding protein1 (SREBP1) participation in the development of DN is reported. Oryzanol concentrate (OC) at 0.1% and 0.3% is tested for its antioxidant and hypolipidemic effects. The aim of the work is to study the involvement of OC in the amelioration of DN in STZ-induced diabetic animal model. METHODS AND RESULTS: Animals were grouped into starch, high-fat, and OC-treated control/diabetic groups (SFC/SFD, HFC/HFD, OFC/OFD). The markers of DN, increased glomerular filtration rate and kidney weight, were evident in HFD and reduced in OFD group by ~1.09 and ~1.3 fold, respectively. The amelioration of defensive antioxidant enzyme activities and lipid peroxidation, expressions of lipid-associated biomolecules (SREBP1 and FAS) were also observed. HFD showed increased ECM accumulation of glycoproteins, particularly Type IV collagen, fibronectin. SREBP1-associated gene transforming growth factor-beta (TGF-beta) was reduced on treatment (OFD ~ 1.3 fold) as to HFD (~2.7 fold). CONCLUSION: Oryzanol concentrate, having hypolipidemic and antioxidant properties, also downregulated the lipid biosynthesis through reduced SREBP1-TGF beta interactions (EMSA) and could effectively ameliorate DN. Gene (ACC2, Cpt1, and ACOX) expression studies showed that beta-oxidation was not involved in reducing DN.

AB - Legume-Rhizobium symbiosis results in root nodules where rhizobia fix atmospheric nitrogen into plant usable forms in exchange for plant-derived carbohydrates. The development of these specialized root organs involves a set of carefully orchestrated plant hormone signalling. In particular, a spatio-temporal balance between auxin and cytokinin appears to be crucial for proper nodule development. We put together a construct that carried nuclear localized fluorescence sensors for auxin and cytokinin and used two photon induced fluorescence microscopy for concurrent quantitative 3-dimensional imaging to determine cellular level auxin and cytokinin outputs and ratios in root and nodule tissues of soybean. The use of nuclear localization signals on the markers and nuclei segmentation during image processing enabled accurate monitoring of outputs in 3D image volumes. The ratiometric method used here largely compensates for variations in individual outputs due to sample turbidity and scattering, an inherent issue when imaging thick root and nodule samples typical of many legumes. Overlays of determined auxin/cytokinin ratios on specific root zones and cell types accurately reflected those predicted based on previously reported outputs for each hormone individually. Importantly, distinct auxin/cytokinin ratios corresponded to distinct nodule cell types indicating a key role for these hormones in nodule cell type identity. PMID- 29469231 TI - Rational Tuning of Fluorobenzene Probes for Cysteine-Selective Protein Modification. AB - Fluorobenzene probes for protein profiling through selective cysteine labeling have been developed by rational reactivity tuning. Tuning was achieved by selecting an electron-withdrawing para substituent in combination with variation of the number of fluorine substituents. Optimized probes chemoselectively arylated cysteine residues in proteins under aqueous conditions. Probes linked to azide, biotin, or a fluorophore were applicable to labeling of eGFP and albumin. Selective inhibition of cysteine proteases was also demonstrated with the probes. Additionally, probes were tuned for site-selective labeling of cysteine residues and for activity-based protein profiling in cell lysates.

AB - We propose a method for the simultaneous determination of 15 kinds of polycyclic aromatic hydrocarbons in marine samples (muscle) employing gas chromatography with mass spectrometry after saponification with ultrasound-assisted extraction and solid-phase extraction. The experimental conditions were optimized by the response surface method. In addition, the effects of different lyes and extractants on polycyclic aromatic hydrocarbons extraction were discussed, and saturated sodium carbonate was first used as the primary saponification reaction and extracted with 10 mL of ethyl acetate and secondly 1 mol/L of sodium hydroxide and 10 mL of n-hexane were used to achieve better results. The average recovery was 67-112%. Satisfactory data showed that the method has good reproducibility with a relative standard deviation of <13%. The detection limits of polycyclic aromatic hydrocarbons were 0.02-0.13 ng/g. Compared with other methods, this method has the advantages of simple pretreatment, low solvent consumption, maximum polycyclic aromatic hydrocarbons extraction, the fast separation speed, and the high extraction efficiency. It is concluded that this method meets the batch processing requirements of the sample and can also be used to determine polycyclic aromatic hydrocarbons in other high-fat (fish, shrimp, crab, shellfish) biological samples. PMID- 29469238 TI - Fire-Retardant and Thermally Insulating Phenolic-Silica Aerogels. AB - Energy efficient buildings require materials with a low thermal conductivity and a high fire resistance. Traditional organic insulation materials are limited by their poor fire resistance and inorganic insulation materials are either brittle or display a high thermal conductivity. Herein we report a mechanically resilient organic/inorganic composite aerogel with a thermal conductivity significantly lower than expanded polystyrene and excellent fire resistance. Co-polymerization and nanoscale phase separation of the phenol-formaldehyde-resin (PFR) and silica generate a binary network with domain sizes below 20 nm. The PFR/SiO2 aerogel can resist a high-temperature flame without disintegration and prevents the temperature on the non-exposed side from increasing above the temperature critical for the collapse of reinforced concrete structures.

PMID- 29469240 TI - Actual Versus Expected Doses of Half Tablets Containing Prescribed Psychoactive Substances: A Systematic Review. AB - Objective: To assess through a systematic review of the literature if the practice of splitting tablets containing psychoactive/psychotropic medications for medical or economic reasons would result in the expected doses. Data Sources: A MEDLINE and PsycInfo comprehensive search of English-language publications from January 1999 to December 2015 was conducted using the terms describing tablet splitting (tablet splitting, split tablets, tablet subdivision, divided tablets, and half tablets) and psychoactive substances (psychoactive medicines, psychotropic medicines, antidepressants, anxiolytics, anticonvulsants, antipsychotics, and antiparkinsonian agents). An additional supplementary search included the references from the articles found. Study Selection/Data Extraction: Studies were included if splitting content was directly related to psychoactive medications and examined the effect of tablet splitting on drug uniformity, weight uniformity, and adherence of psychoactive drugs. Articles were systematically reviewed and examined regarding the study design, methodology, and results of the study. A total of 125 articles were screened, and 13 were selected. Results: Tablet splitting implications are extensive, yet substantial deviations from the ideal weight, potency, and dose uniformity are more prone to be important to patient safety. The uneven division of tablets might result in the administration of different doses than what was prescribed, causing under- or overdosing, which might be relevant depending on the drug. In 55% of the cases, splitting psychoactive drugs was satisfactory. Conclusions: It cannot be generalized that splitting psychoactive drugs compromises dose accuracy, thus tablet splitting might still be employed in cases in which the advantages outweigh the disadvantages. It is recommended that alternatives be adopted to prevent the disadvantages related to tablet splitting. PMID- 29469241 TI - Dealing With a Patient Who Has Given Up.

AB - OBJECTIVE: The aim of this study was to examine (a) whether adventurous and explosive temperament profiles (presumed precursors of antisocial and borderline personality) are associated with character traits over a 15-year follow-up and (b) whether social support and attachment security modify the relationship between temperament profiles and character development. METHODS: 2,028 subjects of the Young Finns study completed the Temperament and Character Inventory, the Multidimensional Scale of Perceived Social Support, and the Relationship Questionnaire at 3 assessment points between 1997 and 2012. RESULTS: Both explosive and adventurous temperament profiles seemed to predispose individuals to have less mature personalities; that is, these profiles were consistently associated with lower cooperativeness (P < .001), and explosive temperament also with lower self-directedness (P < .001), over the entire follow-up period. These relationships did not vary significantly at the individual level and were sustained after controlling for age, gender, and socioeconomic status. However, the presence of high social support and secure attachment was found to decrease the likelihood that explosive temperament would lead to an immature adulthood character (P < .001). In contrast, persons with the adventurous temperament were likely to have a more mature character under low social support and an immature one under high experienced social support (P < .05). CONCLUSIONS: Individuals with the explosive temperament benefit from high social support and secure attachment. From the point of view of the therapy process, this knowledge might be of importance. In contrast, individuals with the adventurous temperament were able to direct their behavior better in social environments that were not likely to support their basic temperaments. PMID- 29469246 TI - Reflective practices: meaningful recognition for healthy work environments. AB - Nurses' decisions about their intent to remain in the workforce are based on various factors. A healthy work environment in which work done well is recognised and appreciated contributes to nurses' satisfaction and better patient outcomes. This article examines the American Association of Critical-Care Nurses framework for a healthy work environment, focusing on standards for meaningful recognition. Reflective practice, which provides a self-analytical approach to appreciate and value one's work, is viewed as self-recognition. Neither boastful nor arrogant, reflective self-recognition is part of progression to professional maturity. It involves examining events at work continuously and systematically to learn, appreciate and move to higher levels of contribution in the workplace. PMID- 29469245 TI - Antipsychotic Prescriptions Among Adults With Major Depressive Disorder in Office Based Outpatient Settings: National Trends From 2006 to 2015. AB - OBJECTIVE: A recent moderately long-term study found an antipsychotic to be more effective than an antidepressant as the next-step treatment of unresponsive major depressive disorder (MDD). It is thus timely to examine recent trends in the pharmacoepidemiology of antipsychotic treatment of MDD. METHODS: Data from the 2006-2015 National Ambulatory Medical Care Survey, nationally representative samples of office-based outpatient visits in adults with MDD (ICD-9-CM codes 296.20-296.26 and 296.30-296.36) (n = 4,044 unweighted), were used to estimate rates of antipsychotic prescribing over these 10 years. Multivariable logistic regression analysis identified demographic and clinical factors independently associated with antipsychotic use in MDD. RESULTS: Antipsychotic prescribing for MDD increased from 18.5% in 2006-2007 to 24.9% in 2008-2009 and then declined to 18.9% in 2014-2015. Visits with adults 75 years or older showed the greatest decline from 27.0% in 2006-2007 to 10.7% in 2014-2015 (OR for overall trend = 0.73; 95% CI, 0.56-0.95). The most commonly prescribed antipsychotic agents were aripiprazole, olanzapine, quetiapine, and risperidone. Antipsychotic prescription was associated with being black or Hispanic, having Medicare among adults under 65 years or Medicaid as a primary source of payment, and receiving mental health counseling, 3 or more concomitant medications, and diagnosis of cannabis use disorder (P < .01). CONCLUSIONS: Antipsychotics, prescribed for about one-fifth of adults with MDD, increased and then declined from 2006 to 2015, reflecting, first, FDA approval and then concern about adverse effects in the elderly. Future research should track evolving trends following the publication of evidence of greater long-term effectiveness of antipsychotic than antidepressant next-step therapy in adults with MDD.

AB - This report presented the endemic status of schistosomiasis in the People's Republic of China at a national level in 2015, and analyzed the data collected from the national schistosomiasis prevention and control system and 457 national schistosomiasis surveillance sites. Among the 12 provinces (municipality, autonomous region) endemic for schistosomiasis japonica in P. R. China, 5 provinces (municipality, autonomous region), i.e., Shanghai, Zhejiang, Fujian, Guangdong and Guangxi, had achieved transmission interruption, and 7 provinces of Sichuan, Yunnan, Jiangsu, Hubei, Anhui, Jiangxi and Hunan had achieved transmission control by the end of 2015. There were 453 endemic counties (city, district) covering 252 million people, specifically including 29 980 endemic villages of 68.61 million people at risk of infection. Among the 453 endemic counties (city, district), 75.72% (343/453) and 24.28% (110/453) reached the criteria of transmission interruption and transmission control, respectively. By the end of 2015, it was estimated of 77 194 cases of schistosomiasis, which were decreased by 33.23% compared with 115 614 cases in 2014. No acute schistosomiasis cases were reported in 2015. There were 30 843 advanced schistosomiasis cases documented in 2015. A total of 8 736 036 individuals received schistosomiasis examinations and 3 606 individuals were parasitologically diagnosed, which were decreased by 56.40% compared with 8 270 cases in 2014. An Oncomelania hupensis snail survey was performed in 19 965 endemic villages and the snails were found in 5 609 villages, accounting for 28.09% of total villages, with 31 newly detected villages with snails. The snail survey covered an area of 593 572.66 hm2 and snails were found in an area of 173 462.50 hm2, including a newly detected area of 666.04 hm2. No infected snails were found in 2015. A total of 879 373 bovines were raised in the schistosomiasis endemic regions. Of them, 526 062 bovines received stool examinations, resulting in 315 infected bovines. There were 170 438 schistosomiasis cases receiving drug treatment in 2015, with 2 449 696 individuals undergoing expanded chemotherapy. There were 318 bovines with schistosomiasis receiving drug treatment, with 483 213 bovines undergoing expanded chemotherapy. A total of 144 305.52 hm2 area was subject to snail control by using molluscicides, with an actual molluscicide-treated area of 69 221.57 hm2, and 4 572.06 hm2 snail habitats were treated by environmental modification. Based on the data from the 457 national schistosomiasis surveillance sites, the mean Schistosoma japonicum infection rate was 0.05% and 0.04% in humans and bovines, respectively. No infected snails were found in all the surveillance sites. The results demonstrate a decline in the endemicity of schistosomiasis in P. R. China and the country reached the criteria of transmission control at the national level. However, the endemic situation of schistosomiasis is unstable in some regions with newly-reached transmission control, and further control and effective surveillance should be strengthened to consolidate the achievements and reduce the endemic situation of schistosomiasis in P. R. China. PMID- 29469249 TI - [Impact of schistosomiasis transmission by catastrophic flood damage and emergency response in China]. AB - Flood damage is one of the ordinary natural calamities. The areas of middle and down of the Yangtze River and its south are the endemic area of schistosomiasis. As the flood damage, it causes property loss, and harm public and people health severely even. This paper aims at the status of catastrophic flood damage again in the Yangtze River basin, analyzes the impact of schistosomiasis transmission by it, and indicates that at present, the process of schistosomiasis control in China is marching from transmission control to transmission interruption and elimination, but the frequent flooding exacerbates Oncomelania hupensis snail breeding area and schistosomiasis source spreading, which may influence, in a certain extent, the realization of the goal of schistosomiasis control in China. We should timely assess and monitor the impact and risk of schistosomiasis transmission by flood damage, and give the early warning and adopt emergency handling measures in time. This paper also proposes the disaster prevention measures according to flood damage stages (the early, middle, later, and post flood) and the occurrence and development of damage and endemic situation, so as to control the risk and damage of the disease transmission in a high limit, to consolidate the current achievements of schistosomiasis prevention and control and guarantee the realization of the goal of schistosomiasis interruption and elimination in China on the schedule.

AB - OBJECTIVE: To investigate the tempo-spatial patterns of schistosomiasis in Jiangling County, Hubei Province, so as to identify the risk areas and provide the scientific evidence in following intervention plans for marshland epidemic areas in the stage of transmission control. METHODS: The schistosomiasis epidemiological data in Jiangling County from 2009 to 2013 together with the related geographical information were collected and analyzed. The tempo-spatial distribution patterns were analyzed by the spatial autocorrelation analysis and spatial clustering analysis. RESULTS: The human infection rate was decreased from 2.15% in 2009 to 0.63% in 2013, which was the historically low level. The results of tempo-spatial analysis showed that there were spatial clustering effects in human schistosomiasis infection for each of the years. The values of spatial autocorrelation index Moran's I were statistically significant. Eighteen and thirty-five clusters were detected by using SatScan and FlexScan software, respectively. CONCLUSIONS: From 2009 to 2013, the schistosomiasis endemic situation in Jiangling County presented a decline trend and reached the historical low level. The identified spatial clustering areas should be targeted as the prioritized areas for schistosomiasis control.

AB - OBJECTIVE: To explore the effect of the autoregressive integrated moving average model-nonlinear auto-regressive neural network (ARIMA-NARNN) model on predicting schistosomiasis infection rates of population. METHODS: The ARIMA model, NARNN model and ARIMA-NARNN model were established based on monthly schistosomiasis infection rates from January 2005 to February 2015 in Jiangsu Province, China. The fitting and prediction performances of the three models were compared. RESULTS: Compared to the ARIMA model and NARNN model, the mean square error (MSE), mean absolute error (MAE) and mean absolute percentage error (MAPE) of the ARIMA-NARNN model were the least with the values of 0.011 1, 0.090 0 and 0.282 4, respectively. CONCLUSIONS: The ARIMA-NARNN model could effectively fit and predict schistosomiasis infection rates of population, which might have a great application value for the prevention and control of schistosomiasis.

AB - OBJECTIVE: To explore the impact of environment factors and social economic factors (environment interference factors for short) and control measures on the endemic status of schistosomiasis in Poyang Lake Eco-economic Region. METHODS: The grey relational analysis model was applied to analyze the relationships between the key indexes of schistosomiasis epidemic status and the environment interference factors and control measures in Jiujiang City of Poyang Lake Eco economic Region. RESULTS: Six environment factors, which included the annual average water level of Poyang Lake, average annual temperature, storm frequency, annual average relative humidity, annual sunshine duration, and annual precipitation, had the most closed relationship with the indexes of schistosomiasis epidemic status (all ri > 0.9). Among the socioeconomic factors, the number of health technicians and beds of health facilities were most associated with the indexes of schistosomiasis epidemic status. Among the control measures of schistosomiasis, the number of cattle treated with extending chemotherapy, chemically killing of Oncomelania hupensis snails and eco renovation were most associated with the indexes of schistosomiasis epidemic status. CONCLUSIONS: The various environment interference factors and their interaction should be considered in formulating the comprehensive control strategy for schistosomiasis, and the control strategy should be adjusted according to the epidemic dynamic and schistosomiasis-focused targets, so as to further strengthen the scientificity and validity of the control strategy.

AB - OBJECTIVE: To explore the cut-off value of the indirect haemagglutination test (IHA) method for schistosomiasis japonica diagnosis in different endemic areas. METHODS: Totally 55 nature villages of the lake-type endemic counties, Yugan and Xinzi, in Poyang Lake Region of Jiangxi Province were chosen as the study fields, and all the villagers over 5 years old were parallelly examined by Kato-Katz method + miracidial hatching test and IHA method. The detection data were analyzed by the correlation analysis, and the threshold values of the IHA method in different endemic areas were decided by the receiver operating characteristic (ROC) curve. RESULTS: The positive rate of stool examinations of the villagers was correlated with the distribution trend of the antibody level of whole population (r = 0.588, P < 0.05), but no correlation with the antibody level of the positive population (r = 0.221, P > 0.05). The antibody level of stool negative population during the period of 2008 to 2011 detected by IHA method dropped year by year, and the annual difference was statistically significant (F = 3.650, P < 0.05). While the antibody level of stool-positive population found during the period of 2008 to 2011 maintained a certain high level in the 4 years, and there was no statistically significant difference among them (F = 2.461, P > 0.05). When the positive rates were <1%, 1%-5% or >5%, the specificity of diagnosis could be improved when 1?80, 1?20 and 1?10 were used as the cut-off values of IHA correspondingly. CONCLUSIONS: The different threshold values for diagnosis of schistosomiasis japonica should be considered while using IHA method to screen out patients in different endemic areas.

AB - OBJECTIVE: To study the effectiveness of comprehensive control measures based on systematic ecological system construction to interrupt the transmission of schistosomiasis in hilly endemic regions in Sichuan Province, so as to provide the evidence for adjustment of schistosomiasis prevention and control strategies. METHODS: A high endemic area of schistosomiasis, Panao Township of Dongpo District in Meishan City, was selected as a demonstration area. The comprehensive measures for schistosomiasis control with focus on systematic ecological management were implemented, and the income of residents, indexes of schistosomiasis control effect and so on were investigated before and after the intervention and the results were compared. RESULTS: The project based on systematic ecological system construction started in 2009 and 317.351 million Yuan was put into the construction. The construction included economic forest plant base (1 866.68 hm2, 72.66% of the total farmland areas), ecological protection gardens (585.35 hm2) and so on. Totally 97.04% of historical areas with Oncomelania hupensis snails were comprehensively improved. In 2015, the peasants' pure income per capita increased 4 938 Yuan, with the average annual growth rate of 14.69%. All the farm cattle were replaced by the machine. The benefit rate of water improvement was increased by 52.84% and the coverage rate of harmless toilets increased by 18.30%. The positive rate of serological tests for schistosomiasis decreased from 7.69% to 3.50%, and the positive rate of parasitological tests decreased from 1.18% to 0. The area with snails was decreased from 23.33 hm2 to 0. The awareness rate of schistosomiasis control knowledge and correct behavior rate of the residents increased from 85.50% and 82.60% to 95.70% and 93.90% respectively. CONCLUSIONS: The comprehensive schistosomiasis control measures based on systematic ecological management are conform to the currently actual schistosomiasis prevention and control work in hilly endemic regions, and have good ecological economic benefit and schistosomiasis control effectiveness, which provide an effectively new model of prevention and control for advancing process, consolidating the effect, finally realizing goal of interruption and elimination of schistosomiasis in hilly endemic regions.

AB - OBJECTIVE: To analyze the channels of going abroad of imported malaria patients in Jiangsu Province, so as to provide the evidence for the control of imported malaria and health intervention for high-risk population. METHODS: The data of imported malaria cases in Jiangsu Province in 2015 were collected and the channels of going abroad were analyzed. The Quantum GIS 1.7.4 software was applied to map. RESULTS: Totally 405 imported cases were reported in Jiangsu Province in 2015, and the cases increased by 14.1% compared with those in 2014. All the patients were migrant workers. The migrant workers were mostly sent abroad by construction companies [43.21% (175/405)]. The dispatching companies were mainly concentrated in Taizhou, Lianyungang, Zhenjiang and Yangzhou cities, accounting for 6.17% (25/405), 3.21% (13/405), 2.72% (11/405) and 2.22% (9/405), respectively. Totally 176 (43.46%) patients returned to China having accompanied workers, and 1.21% (9/745) of accompanied workers were found having symptoms of malaria later. CONCLUSIONS: It is difficult to monitor malaria in overseas migrant works in Jiangsu Province. The channels of going abroad of migrant workers are various and complicated, formulating the main difficulty and challenge of imported malaria control. PMID- 29469256 TI - [Epidemiological analysis of malaria prevalence in Nanjing City from 2010 to 2015]. AB - OBJECTIVE: To analyze the epidemiological characteristics of malaria in Nanjing City, so as to provide the evidence for further formulating and adjusting the malaria prevention and control strategy. METHODS: The data of malaria situation, malaria cases and epidemiological investigations were collected from the Internet Reporting System in Nanjing City from 2010 to 2015 and analyzed statistically. RESULTS: A total of 137 confirmed malaria cases were reported in Nanjing City from 2010 to 2015, including 102 falciparum malaria cases (74.45%), 33 vivax malaria cases (24.09%), one ovale malaria case (0.73%) and one quartan malaria case (0.73%). Among the 137 malaria cases, 126 cases (91.97%) were imported from foreign countries, 2 cases (1.46%) were infected locally, and nine cases (6.57%) were imported from other provinces in China. Among the 126 overseas imported cases, 117 cases were imported from African countries and 9 from Asian countries. These malaria cases were majorly young men working as migrant workers, laborers and technical persons. About 19.30% of the cases went to hospital on onset day, and 55.65% were confirmed by medical institutions as malaria in the same day. The majority of diagnosis institutions were municipal hospitals (74.45%). CONCLUSIONS: The number of malaria cases in Nanjing City is declining year by year. The local infections are eliminating gradually. However, the situation of imported malaria from overseas is still serious. Therefore, the surveillance work and health education still should be strengthened, so as to reduce the risk of imported malaria.

AB - OBJECTIVE: To investigate the epidemiological trend of human intestinal helminth infections in Yancheng City, Jiangsu Province from 2006 to 2015, so as to provide the evidence for formulating further control strategies. METHODS: The surveillance data of human intestinal helminth infections were collected and analyzed in Yancheng City from 2006 to 2015. RESULTS: From 2006 to 2015, 110 746 person-times of residents in Yancheng City were surveyed in Yancheng City, and 1 732 samples were positive of human intestinal helminth infections. The infection rate of human intestinal helminthes was highest in 2006 [4.59% (410/8 941)], and lowest in 2013 [0.19% (23/12 165)]. The infection rate of human intestinal helminthes was significantly decreased over time (chi2 = 27.78, P < 0.001). The human infection rates of Ascaris lumbricoides, hook worm and Trichuris trichura were all decreased over time (Z = -27.75, -22.23 and -16.17, all P < 0.001) from 2006 to 2015, with the reduction rates of 96.57%, 92.31% and 96.47%, respectively. The average EPG of A. lumbricoides, hook worm and T. trichura were 2 534, 360 and 154 respectively, and 1 694 (97.81%) cases were light infections. Totally 1 174 cases of Enterobius vermicularis were found in children under 12 years old, and the cases were decreased over time (chi2 = 12.46, P < 0.001). CONCLUSIONS: The infection rate of human intestinal helminthes in Yancheng City decreases over time from 2006 to 2015, and the control work is effective. The control work of focus groups and environmental management and health education should be strengthened in the future. PMID- 29469258 TI - [Investigation on Toxoplasma gondii infection and awareness of toxoplasmosis related knowledge in women with poor pregnant outcomes in Wuxi City]. AB - OBJECTIVE: To investigate the prevalence of Toxoplasma gondii infection and awareness of toxoplasmosis-related knowledge among women with poor pregnant outcomes in Wuxi City. METHODS: A total of 217 women with poor pregnant outcomes from Wuxi City during the period of January 2011 to December 2015 were randomly selected as the study subjects (a study group), while 250 women with normal pregnancy were served as controls (a control group). The sero-prevalence of T. gondii infection was detected by using ELISA and compared between the study and control groups. The awareness of toxoplasmosis-related knowledge was investigated by using a self-designed questionnaire and compared between the study and control groups. RESULTS: The positive rate of anti-Toxoplasma antibody was 30.88% in the study group, which was significantly higher than that (8.8%) in the control group (chi2 = 36.7, P < 0.01). The positive rates of anti-Toxoplasma IgG and IgM antibodies were 20.74% and 10.14% in the study group respectively, which were significantly higher than those (6% and 2.8%) in the control group (chi2 = 22.53 and 10.74, both P values < 0.01). In addition, the positive rates of anti Toxoplasma, anti-Toxoplasma IgG and IgM antibodies were significantly higher in the women with missed miscarriage, natural abortion, stillbirth and birth defect than those in the women with normal pregnancy (all P values < 0.05). The awareness rates of "Do you hear about Toxoplasma or toxoplasmosis?" (P < 0.01), "Do you know that breeding pet cats or dogs may cause Toxoplasma infection?" (P < 0.05) and "Do you know that pregnancy women require the detection of Toxoplasma infection?" (P < 0.01) were significantly lower in the study group than those in the control group, while no significant differences were seen in the awareness rates of "Do you know that eating hot pot may cause Toxoplasma infection?", "Do you know that the use of chopping block in regardless of cooked and uncooked food may cause Toxoplasma infection?", "Do you know that Toxoplasma infection may transfer from mother to fetus?", "Do you know that Toxoplasma infection may cause adverse pregnant outcomes like abortion, stillbirth or fetal abnormalities ?", and "Do you know that the women infected with T. gondii during pregnancy require treatment?" between the two groups (all P values > 0.05). CONCLUSIONS: This study demonstrates higher prevalence of T. gondii infection in women with poor pregnant outcomes than in those with normal pregnancy in Wuxi City. Considering the harm of T. gondii infection during pregnancy and the low awareness of toxoplasmosis related knowledge in pregnant women, the health education of toxoplasmosis related knowledge should be strengthened, especially for pregnant women, so as to reduce the prevalence of T. gondii infection among pregnant women to improve the better child-bearing and rearing level. PMID- 29469259 TI - [Analyais of Toxoplasma gondii infection and related factors among special population in Changzhou City, Jiangsu Province]. AB - OBJECTIVE: To understand the prevalence of Toxoplasma gondii infection and related factors among special population in Changzhou City, so as to provide the evidence for formulating toxoplasmosis prevention measures. METHODS: The venous blood was collected from participants in Changzhou City for detecting IgG and IgM antibodies against T. gondii by ELISA; and an epidemiological questionnaire investigation was also conducted. RESULTS: Among the total 400 respondents detected, the prevalence of T. gondii infection was 15.0% and the positive rates of IgG and IgM were 15.0% and 0.8%, respectively. The T. gondii infection rates of pregnant women, HIV/AIDS patients, patients with neoplasia, and livestock and poultry breeding and processing workers were 11.0%, 11.0%, 24.0% and 14.0%, respectively. As the age increased, the infection rate of T. gondii showed an upward trend, with the highest infection rate (21.6%) among the group of respondents aged above 50 years. The infection rates of groups with different education levels were statistically different (chi2 = 11.443, P < 0.05), and there was a trend that the infection rate decreased with the increase of education level. The prevalence of T. gondii infection in pregnant women was not significantly associated with the number of pregnancies and gestational age. The infection rate of T. gondii in the live-stock and poultry breeding and processing workers increased with the length of their working years. CONCLUSIONS: The prevalence of T. gondii infection among the special population in Changzhou City is high. Therefore, it is necessary to enhance the health education on the knowledge and information of prevention and control of toxoplasmosis, and to improve the awareness of personal protection, the hygiene practices and diet habits. In addition, more attention should be paid to T. gondii monitoring in the special population. PMID- 29469260 TI - [Splenic lymphocyte immune response induced by intranasal immunization with recombinant Toxoplasma gondii profilin in mice]. AB - OBJECTIVE: To observe the splenocytes immune response elicited by different concentrations of recombinant Toxoplasma gondii profiling (rTgPRF) through the nasal route, and determine the optimal dose. METHODS: Fifty female BALB/c mice were randomly divided into 5 groups. The immunized groups were intranasally administered with 10, 20, 30 MUg or 40 MUg of rTgPRF that was separately dissolved in 20 MUl of phosphate-buffered saline (PBS) on days 0, 14, and 21 respectively, while the control mice were given PBS solution instead. Two weeks after the last immunization, all mice were killed. Under asceptic conditions, the spleens from the immunized mice were dissected, and then the splenocyte proliferative responses in vitro were tested by CCK-8 kit. The levels of IFN gamma, IL-2, IL-4 and IL-10 of splenocyte culture supernatant were detected by ELISA. RESULTS: Compared to the control group, the splenocytes from the 30 MUg and 40 MUg groups exhibited a significantly higher proliferative response to rTgPRF (P < 0.05), and SI from the 30 MUg rTgPRF group was higher than that from the 40 MUg group (P < 0.05). The levels of IFN-gamma in all the immunized groups (P < 0.05) and IL-2 in the 20, 30 MUg and 40 MUg groups were significantly stronger than those in the control (P < 0.05), and the 30 MUg group presented the highest concentrations of IFN-gamma (P < 0.01) and IL-2 (P < 0.01). There were no statistical differences among the groups in the levels of IL-4 and IL-10. CONCLUSIONS: The intranasal immunization with rTgPRF can induce the splenocyteproliferation and Th1-type mediated immunity. The best immunized dose is confirmed as 30 MUg.

AB - OBJECTIVE: To evaluate the risk assessment model of Cryptosporidium laboratory, so as to provide the basis for laboratory personnel engaging in the operation of Cryptosporidium. METHODS: Firstly, the risk factors of Cryptosporidium infection in laboratory were determined by the literature and Delphi, and then the weights of risk factors were determined by fuzzy analytic hierarchy process. A risk assessment model for laboratory biosafety of Cryptosporidium was established. RESULTS: Compared to the indexes, based on the risk assessment model, stool sample processing was the two steps in the laboratory with high risk of infection and high risk factors, with the combination weights of risk possibility and hazard rating were 0.111 and 0.107, respectively. CONCLUSIONS: The risk assessment model established is feasible. It can be used to make some suggestions for the related laboratory staff. PMID- 29469262 TI - [Comparison of Schistosoma japonicum development between single sexual infection and double sexual infection in mice and rabbits]. AB - OBJECTIVE: To observe the development of Schistosoma japonicum after single sexual infection and double sexual infection respectively. METHODS: A single Oncomelania hupensis snail was infected by a single schistosome miracidium. The larva were induced and released from the snail after 60-day incubation at 26 C. The mice were infected by the larva (single sexual infection) and dissected 40 days after the infection. All the worms were collected and the sex of the larvae was determined by the sex of the adult worms. Then, the mice and rabbits were infected by single sex of larvae (single sexual infection) and double sex of larvae (double sexual infection) respectively. The mice and the rabbits were dissected 40 days after the infection. All the worms were collected and measured under a microscope. RESULTS: All the male or female worms were collected from the mice and rabbits after single sexual infection. There were three main forms of worms after dissection of double sexual infection of mice and rabbits: folded mature male and female, male or female. Few folded male and immature female were found. Only the double sexual larva infected mice or rabbits had schistosome eggs in the liver and the liver had typical schistosome egg nodules. The single sexual larva infected mice or rabbits had no schistosome eggs or schistosome egg nodules in the liver tissues. The single male larva could develop to worms with the testis, and with a little smaller size compared to the mature folded male, while the single sexual infection female worm could not develop to the mature stage with much thinner and smaller compared to the mature folded female. CONCLUSIONS: The male or female worms from single sexual infection are smaller than those from double sexual infection (mature worms - folded male and female). So it is necessary to check single sex worms in vessels of intestinal mucosa thoroughly in the sentinel mice when no schistosome eggs were found in the liver.

AB - OBJECTIVE: To investigate the species, density and distribution of the overwintering adult mosquitoes in Taibaihu District, Jining City. METHODS: The overwintering adult mosquitoes were monitored by visual observation in Taibaihu District, Jining City from December 2015 to March 2016. The mosquitoes were collected and dissected to observe the body fat accumulation and ovarian development situation. RESULTS: Totally 1 677 mosquitoes were captured and all of them were Culex pipiens pallens. The highest positive rate of overwintering mosquitoes was in sweet potato cellars and greenhouses, with the positive rates of mosquitoes of 98.25% (56/57) and 81.36% (48/59) respectively. The accumulation of the fat body in the female mosquitoes plummeted from late February, and disappeared in middle March. CONCLUSIONS: The adults of Culex pipiens pallens can over-winter in Taibaihu District, Jining City, and locate in sweet potato cellars and greenhouses mainly. The control work of adult mosquitoes should be strengthened in the overwintering period.

AB - OBJECTIVE: To analyze the endemic situation of schistosomiasis after its interruption of transmission in Xiuzhou District, Jiaxing City, Zhejiang Province, so as to provide the references for future surveillance work. METHODS: The data of schistosomiasis and Oncomelania hupensis snails in Xiuzhou District were collected and analyzed statistically. RESULTS: From 1994 to 2015, totally 975 village-times were investigated for O. hupensis snails, and the accumulated area of 4 385.31 hm2 was surveyed. Twenty former snail sites were reoccurring, with an area of 32.61 hm2. An area of 57.71 hm2 was supplied with snail eradication measures. Totally 11 941 snails were dissected and no schistosome infected snails were found. The serum and stool tests were performed to 221 794 and 3 731 residents respectively, and no local infection cases but four imported cases were found. CONCLUSIONS: The endemic situation of schistosomiasis in Xiuzhou District is stable after the transmission was interrupted. However, there are imported schistosomiasis cases, and therefore, the prevention of imported infection source is the focus of surveillance work. PMID- 29469265 TI - [Analysis of imported malaria epidemic situation and implication for prevention and control strategy in Guangxi Zhuang Autonomous Region in 2014]. AB - OBJECTIVE: To analyze the epidemic characteristics of the imported malaria cases in Guangxi Zhuang Autonomous Region in 2014, so as to assess the transmission risk and explore the prevention and control strategy. METHODS: The data of the malaria epidemic situation in the network direct report system of Guangxi in 2014 and the annual report of malaria epidemic situation in 14 cities were collected. The epidemiological information of the imported malaria cases was analyzed. RESULTS: A total of 184 malaria patients were reported in Guangxi in 2014, with a descent rate of 85.29% when compared to that in 2013 (1 251 cases), and the incidence rate was 0.35/100 000. All the cases were imported from abroad, and four species of Plasmodium were found in their blood samples. The number of falciparum malaria cases was the most (49.46%), followed by the ovale malaria cases (32.07%). All the cases were distributed in 32 counties (districts) of 11 cities, and 65.76% of them were distributed in Shanglin County. Most of the cases were male (98.37%), and those aged in 20-49 years accounted for 87.50%. The imported cases came from 14 countries of Africa (86.41%) and 2 countries of Southeast Asia (13.59%), in which, 48.37% of the cases were imported from Garner. The main occupation of the cases in abroad was gold mining work (86.96%). The cases were reported all the year around, with no obvious seasonality. The interval time of back home to attack of the patients with tertian malaria and ovale malaria was longer. CONCLUSIONS: Africa and Southeast Asia is the main source of imported malaria cases in Guangxi, and the migrant workers returning home may have the risk of malaria recurrence, which should be paid enough attention to. PMID- 29469266 TI - [Investigation on awareness rates of malaria prevention knowledge among residents and students in Huai'an District, Huai'an City]. AB - OBJECTIVE: To understand the awareness status on malaria control knowledge of residents, primary and middle school students in Huai'an District, Huai'an City, so as to provide the evidences for promoting the malaria elimination process in this district. METHODS: Three towns in Huai'an District were selected randomly, and one village, one primary school and one junior middle school in each town were chosen as the investigation sites. The residents over 18 years old, the primary school students in Grade 4 to 6, and the junior middle students in the investigation sites were investigated by questionnaires to understand their awareness status on knowledge of malaria control. RESULTS: Totally 305 residents and 618 students were investigated. The awareness rate of students was 89.97%, and the rates of the junior middle school students and primary school students were 85.94% and 94.10%, respectively, the difference between them was statistically significant (P<0.01). The awareness rate of the residents was 80.98%, which was lower than that of the students (P<0.05). For the students, the awareness rate on "precaution of malaria" (96.74%) was the highest, while that on "drug of malaria" (68.93%) was the lowest. For the residents, the rate on "transmission route of malaria" (95.08%) was the highest, that on "4.26 is Malaria Day" (64.26%) was the lowest. Expect the items of "transmission route of malaria" and "precaution of malaria" (both P>0.05), the differences of the awareness rates on all the other items between the students and residents were statistically significant (all P<0.01). CONCLUSIONS: Although the awareness rates of malaria control knowledge in the population of Huai'an District, Huai'an City have achieved the goal of the relevant requirement, the health education on malaria control still should be strengthened, especially for the primary students, female residents and exported labor service personnel. PMID- 29469267 TI - [Investigation on current situation of malaria blood examinations in township level hospitals of Nantong City]. AB - OBJECTIVE: To understand the quality of malaria blood examinations in township level hospitals, so as to provide the evidence for continuing the malaria blood examinations in the stage of post-malaria elimination. METHODS: A total of 64 township hospitals were investigated and 640 negative malaria blood slides were scored individually according to 10 indicators in "Malaria Elimination Technical Scheme" in 2013 and 2014. The single and multiple indicators were calculated, and the work of blood examinations and situation of technicians were investigated. The data of malaria blood examinations and patient discovery in township hospitals of Nantong City were collected and analyzed during the period of 2011 2014. RESULTS: For the single indicator, 29.5% of the thick blood films did not reach the standard, and 35.8% of thin blood films did not reach the standard. For the multiple indicators, blood slides with more than 4 indicators below the standard (poor quality) accounted for 32.5%. From malaria blood examinations and malaria situation, the number of slides was 194 635 during the period of 2011 2014, and there were no local vivax malaria casesin 4 consecutive years from 2011 to 2014, and local malaria has been effectively controlled in Nantong City. For health facilities where malaria patients initially presented, the township and village level accounted for 16.3%, and county and higher level accounted for 83.7%. CONCLUSIONS: The quality of malaria blood examinations in township level hospitals of Nantong City is not high and the microscopic examination has a relatively low efficiency in the discovery of malaria cases. A new model for malaria blood examinations needs to be further explored. PMID- 29469268 TI - [Epidemiological analysis of malaria prevalence in Taixing City from 2005 to 2015]. AB - OBJECTIVE: To understand the malaria prevalence and epidemic characteristics in Taixing City from 2005 to 2015, so as to provide the evidences for formulating the prevention and control strategy. METHODS: The malaria data of Internet reported cases as well as the reports on epidemiological survey of malaria cases in Taixing City from 2005 to 2015 were collected and analyzed with the methods of descriptive statistics and correlation analysis. RESULTS: A total of 61 malaria cases were reported in Taixing City from 2005 to 2015, including 4 local cases and 57 imported cases. There were 9 cases of vivax malaria, 47 cases of falciparum malaria, 2 cases of malariae malaria, and 3 cases of ovale malaria. There was no seasonality in the occurrence of imported malaria. Though there was no correlation between the times of malaria attack and the duration for going out (r = 0.154, P = 0.253), there was a negative correlation between the former and the timeliness for visiting a doctor (r = -0.312, P = 0.014). CONCLUSIONS: The malaria cases are mainly imported ones in Taixing City, and the Plasmodium species of infection are diverse. Imported malaria overseas remains the key point for malaria control in Taixing City. PMID- 29469269 TI - [Investigation on Toxoplasma gondii infection in reproductive women in Shandong Province]. AB - OBJECTIVE: To investigate the Toxoplasma gondii infection situation and relative factors in reproductive women in Shandong area, so as to provide the evidences for establishing strategies for reducing the birth defects and improving the quality of population. METHODS: A total of 5 386 reproductive women who visited hospitals at county and city levels in Shandong region from January 2013 to December 2015 were treated as the research objects, and their venous blood samples were collected to detect the antibodies (IgG and IgM) against T. Gondii in serum. Meanwhile, the related risk factors of T. gondii infection were surveyed by questionnaires. RESULTS: Among the 5 386 reproductive women, 623 ones were positive for IgG antibody and the positive rate was 11.56%, and 328 ones were positive for IgM antibody and the positive rate was 6.21%. The single factor analysis showed that the pregnant status (chi2 = 13.12, P < 0.01), whether the residences were in downtowns or counties (chi2 = 6.27, P < 0.05), whether having animal contact history (chi2 = 10.46, P < 0.01), and whether eating half-baked foods (chi2 = 21.19, P < 0.01) were related to T. gondii infection. CONCLUSIONS: The T. gondii infection rate of reproductive women in Shandong Province is high; the related risk factors include pregnant status, residence, degree of intimate contact with animal, and whether eating half-baked foods. It suggests that the detection of T. gondii infection and health education in reproductive women should be strengthened. PMID- 29469270 TI - [Investigation on current status of Toxoplasma gondii infection among pregnant women and exploration of risk factors in some areas of Lhasa City, Tibet]. AB - OBJECTIVE: To understand the current status of Toxoplasma gondii (TOX) infection among pregnant women and to explore the risk factors in some areas of Lhasa City, Tibet. METHODS: From 2015 to 2016, 3 districts (counties) of Lhasa City were chosen as the investigation sites, and 200 pregnant women in each district (county) were selected as the investigation objectives. Meanwhile, 450 pregnant women from Xuzhou, Yangzhou, Wuxi cities in Jiangsu Province were chosen as the control. Then the blood samples of the pregnant women both in Lhasa and Jiangsu were detected by ELISA for TOX antibodies IgG, IgM, and the detection results were analyzed and compared. In addition, the individual information of the pregnant women in Lhasa City was surveyed by questionnaires, and the related risk factors of TOX infection were analyzed. RESULTS: Among 600 pregnant women investigated in Lhasa City, there were 99 pregnant women with positive TOX antibodies, and the positive rate was 16.50%, which was significantly higher than that (5.11%) of the pregnant women in Jiangsu Province (P < 0.05). There was no statistically significant difference among the 3 districts (counties) of Lhasa City in the positive rates of pregnant women (P > 0.05). The positive rates of the women who preferred raw meat or had the intimate contact with animal were high. CONCLUSIONS: Compared with Jiangsu Province, the infection rate of TOX among pregnant women in Lhasa City is high. Therefore, the comprehensive measures including health education, early examination and treatment should be taken actively, so as to prevent and control TOX infection in this area.

AB - OBJECTIVE: To investigate the species of Limacodidae and the biological habits on Prunus cerasifera and sycamore in the urban area of Wuhu City, so as to provide the reference for the prevention and control of the diseases caused by Limacodidae. METHODS: Two observation places were selected in the urban area of Wuhu City, and the survey period of the first observation place (A) was from 2014 5-4 to 2014-11-2, and eucleid caterpillar was observed and collected every Sunday (a total of 27 times); the survey period of the second observation place (B) was from 2014-1-5 to 2014-12-28, and eucleid caterpillar was observed and collected every Sunday (a total of 52 times). The eucleid caterpillars were collected by the visual inspection and artificial direct collecting method, and then they were identified and classified by the naked eye direct observation and the direct observation with the help of the anatomical lens in the laboratory. RESULTS: There were seven kinds of identified Limacodidae from the two observation places and their occurrence regularity, the species composition ratio, and natural enemies were understood. CONCLUSIONS: Limacodidae larvae not only are the defoliator of the ornamental forests, but also harm the health of residents, that is they can cause eucleid larva dermatitis. Therefore, we should strengthen the prevention and control of Limacodidae, reducing its impact on the lives of the residents. PMID- 29469272 TI - [Schistosomiasis control progress and endemic situation in Sichuan Province]. AB - OBJECTIVE: To understand the schistosomiasis control progress and endemic situation, so as to provide the evidence for formulating the strategy of schistosomiasis elimination in Sichuan Province. METHODS: The schistosomiasis history data, working reports of schistosomiasis prevention and control, schistosomiasis surveillance data, and data of schistosomiasis prevention and control capacity were collected and analyzed for the schistosomiasis control progress and epidemic situation in Sichuan Province from 2004 to 2015. RESULTS: There were 63 schistosomiasis endemic districts in 11 cities in Sichuan Province, and the standard of schistosomiasis transmission interruption was achieved in the whole province in 2015. Currently, the area with Oncomelania hupensis snails was 2 537.54 hm2, and there were 1 769 advanced schistosomiasis patients. From 2004 to 2015, the accumulated survey area with snails was 433 065.80 hm2, and the area of snail control by molluscicides was 251 259 hm2. There were 26.017 144 million person-times of schistosomiasis blood tests and 7.89 million person-times of chemotherapy. There were 1.276 117 million head-times of cattle that received the schistosomiasis examinations. The schistosomiasis patients and livestock and the area with snails were decreased year by year. Since 2010, there were no local schistosome-infected residents and livestock and since 2004, there were no schistosome-infected snails. However, in some area, the professional personnel were less, the technology and hardware lagged behind, and the schistosomiasis prevention and control capacity was weak. CONCLUSIONS: Sichuan Province achieved the standard of schistosomiasis transmission interruption in 2015. In the future, the comprehensive schistosomiasis prevention and control strategy still should be strengthened, including the promotion of schistosomiasis prevention and control capacity, establishment of sensitive early-warning surveillance system, and implementation of accurate schistosomiasis prevention and control, in order to consolidate the control achievements and realize the aim of schistosomiasis elimination as soon as possible.

METHODS: The teams that took part in the competition were formed from 20 Class A tertiary hospitals, with 2 contestants per team. The competition contents included written examination and skill operation. The written examination involved the life cycle of parasites, immunological basis, detecting techniques, etiological diagnosis etc., and the skill operation involved making and dying thin and thick blood smears, making Kato-Katz's fecal thick smears, as well as microscopic examinations of smears. RESULTS: A total of 40 participants took part in the competition. Their total average score was 97.3+/-22.4 with the pass rate of 15.0%, in which the mean score of theoretical knowledge was 56.6+/ 12.8 with the pass rate of 52.5%, and the mean score of skill operation was 40.8+/-12.4 with the pass rate of 5.0%. In the written examination, the scoring rate of the life cycle of soil-transmitted helminths was the highest (90.0%), and the rate of the basic knowledge of food-borne parasites was the lowest (31.5%). Both the pass rates of blood smear making and examination were higher than those of Kato-Katz's thick smears, and the differences were statistically significant (both P < 0.05). The detection rates of Plasmodium vivax, Plasmodium falciparum, Plasmodium ovale and negative slides of the contestants were 38.8%, 45.0%, 35.0% and 25.0% respectively. As to the microscopic examination of helminth eggs, the detection rate of Trichuris trichiura egg was the highest (87.5%), and the rate of the Sparganum mansoni egg was the lowest (2.5%). The scores of Kato-Katz's thick smear making and examination of the contestants from the provincial level hospitals were higher than those from the city level hospitals (both P < 0.05), and the score of those from teaching hospitals in Kato-Katz's thick smear making was higher than that of those from non-teaching hospitals (P < 0.05). CONCLUSIONS: The technique level of professionals from the clinic laboratory of the Class A tertiary hospitals cannot meet the needs of the diagnosis of parasitic diseases in Jiangxi Province, which should arouse the attention of the health authorities and hospitals.

AB - OBJECTIVE: To analyze the discourse right construction of China's medical aid to Africa, so as to provide evidences for improving the effect and sustainable development of China's medical aid to Africa. METHODS: The documents of the discourse right that China constructed in the medical aid to Africa were selected at different periods as discourse samples. The achievement and deficiency were analyzed from four aspects, namely confident, charismatic, influential, and dominant. RESULTS: China's medical team made much in the discourse right construction in their aid to Africa, but some China's medical team members were still too cautious and too low-key. China's medical team gained the trust of the people of Africa, but the language communication difficulties still hampered in China's medical aid to Africa. Chinese medical team were widely praised by the African society, but in the west, some African media, even China's media still neglected to report China's doctors. China's international discourse right were greatly improved, but western countries still dominated the public opinion. CONCLUSIONS: China should refer to the actual situation of medical aid to Africa to strengthen the construction of discourse right.

AB - OBJECTIVE: To understand the epidemic situation, epidemiological characteristics and clinical features of imported malaria in Donghai County, Lianyungang City from 2005 to 2015. METHODS: The epidemiological data of imported malaria in Donghai County from 2005 to 2015 were collected and analyzed by the descriptive epidemiological method. RESULTS: A total of 126 imported malaria cases were reported in Donghai County from 2005 to 2015, including 101 falciparum malaria cases (80.19%), 13 ovale malaria cases (10.32%), 7 vivax malaria cases (5.56%), 4 quartan malaria cases (3.17%), and 1 case with mixed infection (0.79%). These cases were distributed in 14 towns, and mainly in 4 towns namely Niushan, Tuofeng, Shiliu, and Huangchuan, and the cases in the 4 towns accounted for 63.49% of the total cases. The cases occurred in the whole year, but the peak period of the disease was in April, which was related to the returned time of these patients from foreign countries. All the patients were male and aged from 20 to 55 years, and those aged from 20 to 50 years accounted for 90.70%. CONCLUSIONS: The epidemic situation of imported malaria presents a rising trend in Donghai County in recent 10 years. To control imported malaria, the above mentioned 4 towns with more migrant construction workers and businessmen should be treated as key areas. Meanwhile, the floating population management, disposal of the malaria epidemic spots, mosquito vector monitoring as well as health education should be strengthened.

AB - OBJECTIVE: To discuss the effect of pericardial devascularization plus gastric fundus transaction in advance schistosomiasis patients with portal hypertension. METHODS: Thirty-six advanced schistosomiasis patients with portal hypertension treated with devascularization plus gastric fundus transaction (a portal hypertension group), as well as 10 patients treated with modified Sugiura operation (a modified Sugiura operation group) in the Third People's Hospital of Yangxin County since 2006 were chosen as the observation objects, and the clinical effects of the two groups were observed and compared. RESULTS: The operation time, indwelling time of stomach tube, time to taking food after operation, drainage tube removal time of the portal hypertension group were all shorten than those of the modified Sugiura operation group (all P<0.05). The hospitalization expenses of the two groups were (25 466.00 +/- 2 888.48) Yuan and (34 517.10 +/- 4 948.39) Yuan respectively, and the difference was also statistically significant (P<0.05). The incidence rates of portal thrombosis of the portal hypertension group and modified Sugiura operation group were 33.33% (12/36) and 40.00% (4/10), respectively, and the incidence rates of rehaemorrhagia of the two groups 12 months after the operation were 16.67% (6/36) and 10.00% (1/10), respectively, but the differences had no statistically significance (both P > 0.05). In addition, 1 case with delayed gastric emptying and 1 case with stomal leak of esophagus happened in the modified Sugiura operation group, while no corresponding complications happened in the portal hypertension group. CONCLUSIONS: Pericardial devascularization plus gastric fundus is a relatively easy procedure which has a good short-term clinical effect, and therefore it is suitable for application in primary hospitals. However, its long-term effect still needs further observation. PMID- 29469281 TI - [Advances in research of stem cell therapy for human parasitic diseases: a review]. AB - The stem cell is a class of primitive cells with self-renewal, and multiple pluripotent potential capacities, which can differentiate into multiple specialized cells and generate human organs and tissues. Stem cell therapy is an interventional treatment that introduces new stem cells to damaged tissues, which facilitates the regeneration of trauma, disease and ageing-induced damaged human tissues to repair or replace the damaged tissues, thereby achieving the goal of disease treatment. It has been proved that the stem cell therapy is effective in the treatment of multiple human diseases, including cancer, diabetes, neurological disorders, autoimmune diseases, cardiovascular disorders and blood diseases.

AB - OBJECTIVE: To explore the sample unit size effects of spatial pattern of Oncomelania hupensis population in the marshland schistosomiasis epidemic areas. METHODS: The push-broom method was performed to survey the snails in the study site in a basic unit size of 0.33 m*0.33 m in Poyang Lake region of Jiangxi Province. After combining different amount of survey cells, the aggregation indicators, regression models and aggregating factor index were employed to study the spatial distribution pattern. RESULTS: The snail population was in aggregation pattern and the smaller sampling unit could produce higher degrees of aggregation. The regression models showed that the snails distributed in the form of individual groups with attraction with each other and the aggregation was related with the snail density. The clustering factor index demonstrated that the aggregation was introduced by aggregating behavior habit of the snails and environmental factors, or only by snail habit itself, and the aggregating habit of snails could be expressed better by the smaller sampling unit. CONCLUSIONS: The spatial pattern of O. hupensis population in the marshland schistosomiasis epidemic areas is in aggregation pattern, and the sample unit size can affect the calculation results of the related biological indices.

AB - OBJECTIVE: To study the spatial and temporal characteristics of Oncomelania hupensis in Eryuan County, Yunnan Province from 2005 to 2012, so as to provide the scientific evidence for snail surveillance and control. METHODS: Based on the geographic database of O. hupensis snail distribution from 2005 to 2012, the spatial and local autocorrelation analysis and "hot spots" analysis were applied to analyze the spatial and temporal characteristics of the snails. RESULTS: Percent of frames with O. hupensis snails in Eryuan County decreased as a whole from 2005 to 2012. The spatial clustering of global autocorrelation (Moran's I) was increasing from 2007 to 2012 and all Moran's I values showed statistically significance. The local spatial autocorrelation analysis indicated that the number of villages of High-High type of correlation model increased from 2 in 2005 to 7 in 2012, which mainly clustered in plateau canyon areas. The infected snails with High-High type mainly distributed in plateau basin region in 2007. Further "hot spot" analysis found that the living snails gathered in Xinzhuang, Liantie, Xipo and Taiping nearby areas. CONCLUSIONS: The snail distribution in Eryuan has global and local spatial autocorrelations. The number of villages of High-High type of correlation increased. These findings provide the basis for target control of O.hupensis in the future.

AB - OBJECTIVE: To investigate the prevalence and risk factors of helminthic infections including Schistosoma japonicum, Ascaris lumbricoides and Trichuris trichiura and human immunodeficiency virus (HIV), and find out the association among them in a rural community of southwestern China. METHODS: A community-based cross sectional study was conducted. One town was selected randomly; the infections of S.japonicum, A.lumbricoides and T.trichiura were detected with the modified Kato-Katz thick smear method and HIV infection with the diagnostic Test Kit among all residents. A questionnaire survey was conducted to investigate the related risk factors. RESULTS: Among the participants, the infection rates of HIV, S.japonicum, A.lumbricoides and T.trichiura were 2.33%, 2.05%, 13.47% and 30.59% respectively; 7.08% (31/438) were infected with both A.lumbricoides and T.trichiura; 0.23% (1/438) were co-infected with HIV and A.lumbricoides, and the same with HIV and T.trichiura. The multivariate logistic regression analysis showed that sex (male, OR=3.26, 95% CI:0.97, 10.95) and drug abuse (OR=72.86, 95% CI:18.51, 286.76) were significantly associated with HIV infection. Home toilet was negatively related to A.lumbricoides infection (OR=0.52, 95% CI:0.27, 0.98) and T.trichiura infection (OR=0.48, 95% CI:0.28, 0.80). Compared with the people in Villages Four, the people living in Village One were at a higher risk for A.lumbricoides infection (OR=3.14, 95% CI:1.35, 7.27), and compared with the people living in Village Four, the people living in Village Two and Village Three were more likely to be infected with T.trichiura (OR=3.73, 95% CI:1.92, 7.26; OR=4.53, 95% CI:2.12, 9.68). The people aged between 11 and 20 years had a higher T.trichiura infection risk than the people aged more than 50 years (OR = 3.72, 95% CI:1.59, 8.67). There was a significant association between A.lumbricoides and T.trichiura infections (OR = 3.11, 95% CI:1.63, 5.93). There was no association between S.japonicum infection and related factors above mentioned. CONCLUSIONS: The infection rates of HIV, S.japonicum, A.lumbricoides and especially T.trichiura were rather high in this area, and therefore, the prevention and treatment of these diseases should be strengthened. Further studies on the relationship between HIV and the infections of helminths, especially S.japonicum are needed.

AB - OBJECTIVE: To investigate the infection situation of blood parasitic protozoa in farmed Macaca fascicularis in an animal breeding ground in Nanning, Guangxi Zhuang Autonomous Region, so as to provide the evidence for the prevention and control of human blood parasitic protozoa. METHODS: A total of 993 blood samples from farmed M. fascicularis were collected and stored on FTA cards. Among them, 550 thin blood smears were made. Each 10 samples were mixed in groups, and then the Babesia spp. and Plasmodium spp. in the blood of M. fascicularis were detected by Nest-PCR and PCR, respectively. The positive groups were tested individually. The thin blood smears stained with Giemsa were examined microscopically when PCR reported the samples were positive. RESULTS: When detected by Nest-PCR, the positive rate of Babesia. microti was 6.95% (69/993); only 1 positive sample with Plasmodium inui was detected by PCR. Among the 22 positive thin blood smears detected by PCR, 16 were determined with B. microti by microscopic examinations, on which the ring forms could be observed in the erythrocytes, but no hemozoin. CONCLUSIONS: The positive rate of B. microti in M. fascicularis in Guangxi Zhuang Autonomous Region is high, and the animal may play a role as a reservoir host in the transmission of B. microti. In the screening of B. microti with low infection density, Nest-PCR has a higher sensitivity.

AB - OBJECTIVE: To understand the breeding situations of mites and insects from bed mats in dormitories in a college in Wuhu City, so as to provide evidences for improving the prevention and control of mites. METHODS: From March to May, 2015, the dust samples from bed mats in student dormitories were collected and detected for mites and insects by microscopy. In addition, the intervention measures including soaking the mats in the warm water, exposing the mats to the sunlight for a long time and cleaning up the indoor environment were carried out, and the breeding situations of mites and insects before and after the intervention were compared. RESULTS: A total of 428 dust samples from bed mats were collected, and the total infestation rate of mites and insects was 71.03%. There were 11 species of mites and insects identified, among which, the infestation rate of Dermatophagoides farinae (60.05%) was the highest, following by that of Liposcelis bostrychophilus (40.89%) . The infestation rates of Cheyletus malaccensis, Blattisocius sp. and Pyemotes sp. were 9.81%, 3.74% and 1.64%, respectively, and the above mites might cause dermatits. The infestation rates of mites and insects in dust samples from bed mats stored in indoor corner, wardrobe, bed bottom, and the balcony corner were 74.75%, 71.26%, 61.17%, and 77.78%, respectively, and the differences among them were not statistically significant (chi2 = 7.030, P > 0.05) . The detectable rates of mites and insects in dust samples from bed mats with no cover, wrapped with cloth bags, and wrapped with plastic bags were 85.58%, 78.13%, and 14.29%, respectively, and the differences among them were statistically significant (chi2 = 164.303, P < 0.05) . After the intervention, both the infestation rates of mites and insects as well as the average density of mites were decreased, and the differences were statistically significant (chi2 = 45.615, t = 3.203, both P < 0.05) . CONCLUSIONS: The infestation rates of mites and insects in bed mats of the dormitories in the college of Wuhu City are high, and among all the species of mites infested, D. farina are preponderant. The intervention measures, such as prepacking bed mats by adequate sealing, soaking bed mats in the warm water, exposing the bed mats to the sunlight and cleaning indoor environment, have an inhibiting effect to the infestation of mites and insects. PMID- 29469290 TI - [Evaluation of Wondfo Rapid Diagnostic Kit for detecting Plasmodium ovale and analysis of influencing factors]. AB - OBJECTIVE: To evaluate the Wondfo Rapid Diagnostic Kit (Pf-LDH/Pan -pLDH) for detecting Plasmodium ovale and analyze the influence of parasitaemia, concentration and polymorphism of pLDH on the performances. METHODS: A total of 100 blood samples from P. ovale patients confirmed by PCR were detected with the Wondfo Rapid Diagnostic Kit according to the manufacturers'instructions. The parasitaemia was determined by the microscopic examination. The concentration of pLDH was measured by ELISA tests. The LDH gene of P. ovale was amplified by PCR and sequenced. The influence of these three factors on the positive rate was analyzed. RESULTS: The overall positive rate of Wondfo Rapid Diagnostic Kit was 70.0% (70/100). The positive rate was 27.3% for the samples with parasitaemia <= 500 parasites/MUl and reached 75.0%-75.4% when parasitaemia > 500 parasites/MUl. The positive rate was 6.7% for samples with a low pLDH concentration (A values <= 0.100) and reached 95.1%-100% at a high pLDH concentration (A values > 0.100). The results of sequence analysis indicated that all the samples could be divided into 2 types, P. o. curtisi and P. o. wallikeri. The gene homology of LDH between 2 types was 97%. There were 24 single nucleotide polymorphism (s) (SNPs) between 2 types, while only 3 SNPs were non-synonymous mutations. The homology of LDH amino acid sequences between 2 types was 99%; only 3 amino acids were different. The positive rates for P. o. curtisi and P. o. wallikeri were 73.1% (38/52) and 66.7% (32/48) respectively; there was no statistically significant difference (P > 0.05). CONCLUSIONS: The Wondfo Rapid Diagnostic Kit (Pf-LDH/Pan-pLDH) performs better than most of the similar products for the detection of P. ovale, and the positive rates are closely related to the parasitaemia and concentration of pLDH, while no related to the polymorphism of pLDH gene.

AB - OBJECTIVE: To prokaryotic express and identify the recombinant plasmids containing the genes or gene segments which coding secreted or peripheral membrane protein of Schistosoma japonicum. METHODS: A number of 28 pET32 (+) previous constructed recombinant plasmids containing these genes or segments were transferred into E. coli BL21 (DE3) strain for culture via the CaCl2 transformation method, and then induced by IPTG for prokaryotic expression. Then, the bacteria were treated by broking the wall with ultrasonic, and the bacterial suspension, supernatant and precipitation were detected with 12% SDS-PAGE. The size and distribution of these target proteins were determined. Finally, the expression of the recombinant fusion protein was further identified by the protein microarray combined with anti-His tag fluorescent antibody. RESULTS: Under the inducing conditions of 0.1 mmol/L IPTG, 37 C, 200 r/min and 4 h, these fusion proteins were highly expressed in E. coli BL21 (DE3). The SDS-PAGE results showed all the 28 recombinant fusion proteins were expressed in different degrees, among which 2 were distributed in the supernatant, and the other 26 were distributed in precipitation, and the sizes of the fusion proteins were the same as that of prediction. The fluorescent signals of His antibody were successfully detected by confocal laser scanner. CONCLUSIONS: A series of recombinant plasmids containing genes or gene segments that coding secreted protein and peripheral membrane protein of S. japonicum have been successfully expressed by using an efficient prokaryotic expression system of E. coli. It has established a foundation for the high throughput immunoscreening of the vaccine candidates or diagnostic antigens of S.japonicum.

AB - OBJECTIVE: To study the influence of sex on the generation and function of T follicular helper (Tfh) cells in the process of Schistosoma japonicum infection. METHODS: Totally 50 schistosomiasis patients were selected in the endemic areas of Chizhou City, Anhui Province, and totally 50 healthy people were selected in the non-endemic areas of Chizhou City as the controls. The peripheral bloods were collected from the above study subjects, and the human peripheral blood mononuclear cells from male/female schistosomiasis japonica patients or healthy controls were collected into the sodium heparin tubes and purified by Ficoll paque plus density gradient centrifugation. Then, the percentages of total Tfh cell, ICOS+ Tfh cells, and PD-1+ Tfh cells in the schistosomiasis male/female patients or healthy controls were evaluated by flow cytometry. RESULTS: Compared with the male and female healthy controls, the frequency of the total Tfh cells (Umale = 149.0, Ufemale = 39.5, both P < 0.01), the percentages of PD-1+ Tfh cells (tmale = 5.9, tfemale = 7.7, both P < 0.01) and ICOS+ Tfh cells (tmale = 3.2, tfemale = 5.9, both P < 0.01) of the male and female patients with schistosomiasis increased, all the differences were statistically significant. The further analysis showed that the percentage of total Tfh cells (U = 187.5, P < 0.05), ICOS+ Tfh cells (t = 3.2, P < 0.05), and PD-1+ Tfh cells (t = 3.0, P < 0.05) of the female patients were markedly higher than those of the male patients, all the differences were also statistically significant. CONCLUSIONS: Sex may be a crucial role in the generation and function of Tfh cells in the process of Schistosoma japonicum infection.

AB - OBJECTIVE: To evaluate the effect of hydraulic schistosomiasis control project with ditches managed on Oncomelania hupensis snail control. METHODS: From 2009 to 2011, the snail investigations and schistosomiasis surveillance were carried out in Dali City and Yongsheng County, two sites of national schistosomiasis surveillance. The history data of schistosomiasis control were collected and analyzed. RESULTS: At the harden sections of the water conservancy project with ditches managed in Shajing Village of Dali City, only one snail was found in 2010 with the density of living snails of 0.004 snails/0.1 m2, while the densities of living snails were respectively 0.080, 0.002 snails/0.1 m2 and 0.007 snails/0.1 m2 in unhardened sections of the project from 2009 to 2011. No snails were found in the harden sections of the water conservancy project with ditches managed in Gaojiacun Village of Yongsheng County, while the densities of living snails were respectively 0.040, 0.030 snails/0.1 m2 and 0.040 snails/0.1 m2 in unhardened sections of the project from 2009 to 2011. After the ditches were hardened, no infected snails were found from 2009 to 2011, and the appearance rate of frames with snails and density of living snails were both decreased, while they were both higher in unhardened ditches. CONCLUSIONS: The hydraulic schistosomiasis control project has obvious effect on control snails, but the maintain work should be strengthened after the project is completed.

AB - OBJECTIVE: To understand the epidemic status of human intestinal parasitic diseases and evaluate the effect of the control program in Nanping City, so as to provide an evidence for improving the disease control. METHODS: The villages were selected by the stratified cluster sampling method and the residents in these villages were surveyed for human intestinal parasitic diseases, and kindergartens were also selected and the children in these kindergartens were surveyed for Enterobius vermicularis infection. RESULTS: In 2007, before the control program, 9 851 residents of Nanping City were surveyed, with the parasitic infection rate of 9.10% (896 infection cases), and the infection rate of E. vermicularis of children was 18.56% (328/1 767). From 2011 to 2014, when the control program was performed, 4 679 residents were surveyed, with the infection rate of 4.06% (190 infection cases), and the infection rate of E. vermicularis of children was 3.87% (33/853). After the control program was launched, the infection rates of human intestinal parasites were decreased. The overall parasitic infection rate and hookworm infection rate showed increasing trends by age (chi2 = 49.03 and 53.58 respectively, both P < 0.01). CONCLUSIONS: The infection situation of human intestinal parasites is decreased after the implementation of the control program but the infection rate is still at a high level, and the control work should be strengthened. PMID- 29469298 TI - [Analysis of epidemic situation of malaria in Longlin Various Nationalities Autonomous County in Guangxi from 1951 to 2014]. AB - OBJECTIVE: To analyze the data of epidemic situation of malaria in Longlin Various Nationalities Autonomous County, Guangxi Zhuang Autonomous Region, China from 1951 to 2014 and discuss the distribution characteristics and epidemic law, so as to provide the evidences for developing the prevention and control strategies of the disease. METHODS: The data about the epidemic situation of malaria in Longlin Various Nationalities Autonomous County were collected and analyzed statistically with Excel 2007. RESULTS: Totally 93 460 malaria cases were reported from 1951 to 2014 in the county. There were two morbidity peaks of malaria during this period, namely 1950s and 1970s, and the annual average incidence rates were 3 237.94/100 000 and 1 572.12/100 000, respectively, but it began to flatten after 1980s. Before 2000, the local cases were the main type, however, there were no endogenous cases since 2008. In 1950s, falciparum malaria was the main type of the disease, and the cases with falciparum malaria, tertian malaria and quartan malaria were accounted for 45.01% (2 392/5 314), 33.72% (1 792/5 314) and 19.55% (1 039/5 314), respectively; while in 1960s, the proportion of cases with tertian malaria increased, that of the cases with quartan malaria decreased, and there were no quartan malaria cases reported since 1980s. There were imported malaria cases reported since 1990s, and a total of 51 cases were found in this period, among which, 50 cases (98.04%) were tertian malaria, and the main infection sources were the cases from epidemic areas in other provinces of China. After 2000, the imported malaria cases with falciparum malaria increased, with a proportion of 60.00% (21/35), and the infection sources were mainly from Africa and Southeast Asia. CONCLUSIONS: The local endemic of malaria in Longlin Various Nationalities Autonomous County has been effectively controlled, but the situation of imported malaria is still severe in this county. Therefore, strengthening the surveillance of floating population, especially the workers backing from overseas, is still the key of malaria prevention and control in the future.

AB - OBJECTIVE: To analyze the change of endemic situation of schistosomiasis in Jingzhou City of Hubei Province, so as to provide evidence for the development of future control strategy. METHODS: The data of endemic situation of schistosomiasis and the implementation of integrated control measures were collected and analyzed in the 9 counties (districts, cities) of Jing-zhou City from 2004 to 2014. RESULTS: The endemic situation of schistosomiasis appeared a decline year by year since 2004. The prevalence of human Schistosoma japonicum infection was 0.40% in 2014, which was reduced by 95.72% as compared to that in 2004, and the fitting exponential equation was y = 11.067e-0.240x. The incidence of acute schistosomiasis reduced to less than 0.5 per 100 000 in 2007. No acute infection was found since 2010, and no emergency epidemics occurred for successive 9 years. It was estimated that there were currently 22 547 people infected with S. japonicum, which reduced by 85.87% in relative to 2004. The prevalence of cattle S. japonicum infection reduced to 0 in 2014, with a 100% reduction as compared to that in 2004, and the fitting exponential equation was y = 15.69e-0.339 8x. The actual Oncomelania hupensis snail area was 31 084.00 hm2, which reduced of 1931.21 hm2 as compared to that in 2004, with a 5.91% reduction, and no schistosome-infected snails were found since 2012. Both human and animal schistosome infections reduced to less than 1% in all administrative villages in 2013. CONCLUSIONS: The implementation of the key schistosomiasis program and whole-county promotion and province-ministry joint integrated control program results in effective control of schistosomiasis in Jingzhou City. However, further control programs are required to consolidate the achievements, interrupt and eliminate schistosomiasis.

AB - OBJECTIVE: To explore the impact of self-efficacy on the behavior of contacting schistosome cercarial infested water among middle school students. METHODS: In the transmission control area and endemic control area of the schistosomiasis endemic regions in Hubei Province, a total of 3 204 middle school students were selected through the stratified cluster random sampling method and investigated by questionnaires. RESULTS: The incidence rates of contacting infested water with Oncomelania hupensis snails during the past 3 and 12 months among the middle school students were 11.4% (364/3 204) and 14.8% (474/3 204) respectively, while those of contacting indefinite infested water during the past 3 and 12 months were 23.8% (762/3 204) and 28.0% (898/3 204) respectively. The awareness rate of schistosomiasis prevention and control knowledge was 82.1% (2 631/3 204). There were "knowledge-practice separation"in the prevention and control of schistosomiasis among the middle school students. The correlation analysis and Logistic regression analysis showed that the self-efficacy of schistosomiasis protective behavior of middle school students was a protective factor for contacting with infested water, with the adjusted odds ratio values of 0.882, 0.886, 0.914 and 0.927. CONCLUSIONS: Self-efficacy of schistosomiasis protective behavior is a protective factor for contacting with infested water among middle school students, and improving their self-efficacy may be an effective strategy to settle the problem of"knowledge-practice separation".

AB - OBJECTIVE: To prepare the egg yolk immunoglobulin (IgY) against soluble egg antigen (SEA) of Schistosoma japonicum, and explore its feasibility for schistosomiasis screening in endemic areas. METHODS: The urine samples of indirect haemagglutination test (IHA) positives from endemic areas and healthy people from non-endemic areas were collected. The Anti-SEA IgY was obtained through immunization by subcutaneous injection of SEA into Laihang hen, and its molecular weight was determined by SDS polyacrylamide gel electrophoresis (SDS PAGE) . The circulating soluble egg antigen (CSEA) in the urine of IHA positives and healthy people were detected by ELISA-double antibody sandwich method with the Anti-SEA IgY as the capture antibody. RESULTS: Anti-SEA IgY was prepared and purified successfully. Totally 48 urine samples of IHA positives were detected by ELISA and 26 of them were CSEA positives (54.17%); 10 urine samples of healthy people were detected, and all of them were negative. CONCLUSIONS: The CSEA in human urine can be detected effectively by ELISA based on IgY. As a convenient and atraumatic method, it could be applied in schistosomiasis screening.

AB - OBJECTIVE: To understand the breeding and morphology of Lepidoglyphus destructor in college canteens in south Anhui Province. METHODS: The powder and rice on the floor around dough makers, flour bags and rice bags in college canteens were collected and observed under a microscope. RESULTS: Totally 108 samples were collected, and Acaroid mites were found in 101 of them with a detection rate of 93.52%. Totally 1 527 mites were found with an average breeding density of 1.41/g. Under the light microscope observed, the L. destructor's four pairs of legs were tapering from tarsus. The back setae were stiff and the ventral setae were smooth and relatively short. The internal vertical seta was longer than the top of the chelicera. Dorsal seta d3, d4, lateral seta l3 and sacral inner hair sai were the longest. The female mites were bigger than the male ones, and had more anal seta than male ones. The genital fold of female mites almost connected together, and the front-end had a crescent shaped plate cover. CONCLUSIONS: The breeding of Acaroid mites in college canteens is serious, and therefore, effective measures should be taken to prevent and control it.

AB - OBJECTIVE: To analyze the malaria monitoring situation in Shaoguan City from 2001 to 2014, and evaluate the efficacy of the malaria control and prevention work, so as to provide the evidence for formulating the effective eliminating malaria measures. METHODS: The microscopic examination monitoring points of "four-fever" patients were established in medical institutions at all levels in Shaoguan City from 2001 to 2014, and the fever patients were examined by microscopy and the active case monitoring was performed. By using the epidemiology method, the malaria incidence and classification of cases were described and analyzed statistically. RESULTS: From 2001 to 2014, 91 381 "four-fever" patients were monitored and 22 malaria patients were found with the average positive rate of 0.02%. Among the 22 malaria patients, 20 were imported (90.91%) and 2 were local cases (9.09%). The local patients were infected with Plasmodium vivax, and among the imported patients, 16 patients were infected with P. vivax, 2 infected with P. falciparum and 2 infected with P. ovale. No local infection cases were found since 2006. All the patients were timely treated and no second generation cases were found. From 2011 to 2014, 2 611 person-times were actively investigated in 7 counties (city) and no malaria patients were found. CONCLUSIONS: In Shaoguan City, there are remarkable achievements in the malaria prevention and control work. However, there are still imported cases in recent years, and therefore, the monitoring system should be perfected and the effective monitoring should be strengthened.

AB - OBJECTIVE: To understand the endemic dynamics and situation of schistosomiasis in a provincial surveillance site in Haining City, Zhejiang Province. METHODS: The Oncomelania hupensis snail status, schistosome infection situations of permanent residents and floating population in Qinmin Village, Haining City were monitored from 2012 to 2014 according to The Surveillance Programs of Schistosomiasis in Surveillance Sites of Zhejiang Province. RESULTS: Totally 600 permanent residents were examined from 2012 to 2014. The total positive rate of the serum antibody against Schistosoma japonicum was 3.17% (19/600). The rates in each year were 2.50% (5/200), 0 (0/200), and 7.00% (14/200), respectively, and the rate in 2014 were significantly higher than that in 2013 (chi2 = 14.508, P < 0.01), but no positives were found in the fecal examination. Totally 1 591 floating population were involved in the surveillance, the positive rate of serum antibody were 0.94% (15/1 591). The rates in active surveillance and passive surveillance were 0.92% (14/1 521) and 1.43% (1/70), respectively, and there were no statistically significant difference between them (chi2 = 1.659, P > 0.05). The positive rates of serum antibody among each year were 1.50% (8/534), 0.56% (3/531), and 0.76% (4/526), respectively, and the difference was not statistically significant (chi2 = 2.752, P >0.05), but no positives were found in the fecal examination. The snail surveillance showed that there were no environments with infected snails and imported snails. CONCLUSIONS: There exist the infection sources of schistosomiasis in Haining City. Therefore, we should be on high alert for the potential of local endemic of the disease. Meanwhile, we still should strengthen the snail surveillance as well as the infection surveillance among the floating population.

PMID- 29469312 TI - [Epidemiological characteristics of canine Echinococcus infection in Qinghai Tibet Plateau of China]. AB - The Qinghai-Tibet Plateau is known as one of the highest endemic areas of echinococcosis. However, the dog infection rates of Echinococcus granulosus in the plateau regions were similar to other non-Tibetan areas with the high endemic, and most of the rates were below 40%. The infected dogs with E. multilocularis were ubiquitous in Ganzi Prefecture of Sichuan Province and Qinghai Province where many survey data were done and available, which was much different from those in non-Ti-betan areas where the geographical distribution of dogs infected with E. multilocularis was sporadic. The total infection rates of Echinococcus in dogs kept stable from 1983 to 2009 in Ganzi Prefecture of Sichuan Province and did not show much variation from 2000 to 2014 in Qinghai Province as well. Since 2006, the national comprehensive prevention and control strategy and measures against echinococcosis have been launched in China, and significant progress has been made. In the endemic Tibetan area of Sichuan, the general Echinococcus infection rates in dogs were 28.10%, 15.87%, 19.22%, 3.28% and 1.11% from 2009 to 2013, respectively, and the Echinococcus coproantigen-positive rate in Gannan Prefecture of Gansu Province and parts of Qing-hai Province also decreased. This paper reviews the literature on the characteristics of dog infections in the Qinghai-Tibetan Plateau, so as to provide useful information to support echinococcosis control and prevention there.

AB - OBJECTIVE: To understand the epidemical patterns of schistosomiasis in Guichi District of Chizhou City, Anhui Province, in order to provide the reference for schistosomiasis control. METHODS: The annual data of schistosomiasis endemic situation in Guichi District from 1991 to 2011 were collected. The descriptive analysis was first conducted to describe the changes of schistosomiasis in local residents and the status of Oncomelania hupensis. An autoregressive integrated moving average (ARIMA) model was applied to fit and predict the tendency of schistosomiasis incidence in this region. RESULTS: The human morbidity increased with the increasing of the areas with snail habitats (P < 0.05), and four peaks (in 1992, 1995, 2005, 2008) were detected. The difference of the area with snails among different types of snail habitats was statistically significant (F = 256.79, P < 0.05). ARIMA (1, 1, 1) was determined to be the optimal model for analyzing the morbidity of schistosomiasis, and the short-term forecast of the morbidity in Guichi District from 2012 to 2015 showed that the predicted values were 0.017%, 0.007%, 0.012%, and 0.010%, respectively. CONCLUSIONS: The endemic situation of schistosomiasis in Guichi District is controlled relatively well in the past two decades. However, the surveillance in the lake and marshland regions should be strengthened continuously to prevent the rebounding of the schistosomiasis endemic situation.

AB - OBJECTIVE: To explore the epidemiological characteristics of malaria in Liaoning Province from 1951 to 2014, so as to provide the evidence for further control of the disease. METHODS: The data of registered malaria cases in Liaoning Province from 1951 to 2014 were collected and analyzed with epidemiological methods. RESULTS: From 1951 to 2014, there were reported malaria cases each year. The peaks of incidence were in 1953, 1962 and 1973, the incidence rates were 136.67/100 000, 256.81/100 000 and 35.89/100 000 respectively and the numbers of patients were 27 862, 65 460 and 11 523, respectively. From 1977 to 2014, the incidence rates were all less than 1/100 000. From 1951 to 1980, the occupations of patients were mainly farmers, and from 1981 to 2014 were mainly workers, farmers and exported laborers. CONCLUSIONS: The malaria endemic situation in Liaoning Province experienced the periods from outbreaks to basically elimination, and the long-term surveillance will be the further working emphasis.

AB - OBJECTIVE: To study the cyfluthrin resistance and potential mechanisms of Anopheles sinensis in Nanchang Chang-bei International Airport, Nanchang City, Jiangxi Province. METHODS: The resistance levels of the local An. sinensis were detected by WHO drug resistance bioassay. During the bioassay, the dying mosquitos were classed as sensitive mosquitos, and the survival ones were classed as resistant mosquitos. The P450 monooxygenase activity and glutathione S transferase activity were detected and compared between the two groups. At the same time, the death time of each sensitive mosquito was recorded, and the correlations between the death time and the P450 monooxygenase activity and glutathione S-transferase activity were analyzed, respectively. RESULTS: The bioassay mortality of the local An. sinensis was 59.5%. The differences of the P450 monooxygenase activities among the resistant mosquitos, sensitive mosquitos and laboratory sensitive mosquitos had statistical significances (F =151.89, P < 0.01), the resistant mosquitos > sensitive mosquitos > laboratory sensitive mosquitos. The differences of glutathione s-transferase activities among the three groups had no statistical significance (F = 0.72, P = 0.49). There existed positive correlation between the mosquito death time and the P450 monooxygenase activity, and the regression equation was y = 79.479 +1.512x with the correlation coefficient of 0.88, while there was no correlation between the mosquito death time and the glutathione S-transferaseactivity. CONCLUSIONS: The An. sinensis in Nanchang Changbei International Airport has been resistant to cyfluthrin, and the promotion of P450 monooxygenase activity maybe one of the reasons for the resistance.

AB - OBJECTIVE: To analyze the clinical features of 6 patients with imported schistosomiasis mansoni, including the epidemic history, clinical manifestations, laboratory tests and therapeutic effect, so as to provide references for improving the levels of diagnosis and treatment of physicians. METHODS: The clinical data of 6 patients with imported schistosomiasis mansoni from January 2009 to July 2016 were collected and analyzed. RESULTS: All the 6 imported patients with schistosomiasis mansoni had a clear history of cercarial infested water exposure. The main manifestations were continuous fever and eosinophilia. Three (50%) patients were accompanied with diarrhea. Anti-Schistosoma japonicum IgG antibody were cross positive in 2 (33.3%) patients, while live eggs of S. mansoni were explored in intestinal mucosa specimens of all the patients. CD3+CD8+ T cell ratio was decreased significantly but B cell ratio was elevated in all the patients, and the main immunoglobulin of the patients was IgG. Hydroperitoneum and splenomegaly signs were discovered by abdominal ultrasonography in 16.6% (1/6) of the patients. Multiple liver nodules and wall thickening of rectum and sigmoid colon were revealed by pelvic MR scan in 16.6% (1/6) of the patients. Colitis was found in all the patients, and 66.6% (4/6) of the patients were combined with multiple colonic ulcers by the electronic colonoscopy examination. Chronic inflammation and eosinophil infiltration were found in all the patients by rectum pathology. All 6 patients were cured with chemotherapy named praziquantel. CONCLUSIONS: Comprehensive analysis of clinical data including epidemiological history, specific manifestations, laboratory tests and intestinal mucosa pathology may be benefit of the management of schistosomiasis mansoni.

AB - OBJECTIVE: To assess the theoretical knowledge and practical skills of parasitic diseases among technicians from disease control and prevention institutions. METHODS: The Assessment on National Parasitic Disease Control and Prevention Techniques was organized in September, 2015. Together, 124 subjects from disease control and prevention institutions at province, prefecture or county levels in 31 provinces joined the assessment. A database was built consisting of subjects' basic information and assessment scores. Statistical analysis was used to analyze the scores by gender, age, professional title, institutions and places of participants. RESULTS: The average total score of all the subjects was 123.3, with a passing rate of 57.3%. The average scores of male subjects (48 subjects) and female subjects (76 subjects) were 125.9 and 121.7 respectively; the average scores of the subjects aged under 30 years (57 subjects), between 30 and 40 years (61 subjects) and above 40 years (6 subjects) were 119.6, 128.1 and 111.2 respectively; the average scores of persons with junior (94 subjects), intermediate (28 subjects) and senior (2 subjects) professional titles were 119.2, 135.9 and 140.5 respectively. The average theoretical assessment score of all the subjects was 61.9, with a passing rate of 62.9%. The average practical skill assessment score of all the subjects was 61.4, with a passing rate of 58.1%. CONCLUSIONS: The theoretical assessment results range widely. The theoretical knowledge results of technicians from disease control and prevention institutions are low in general. Therefore, the specific training based on daily work needs to be enhanced.

AB - OBJECTIVE: To optimize the extraction methods of mitochondrial genome DNA (mtDNA) of Oncomelania hupen- sis. METHODS: The pyrolysis, protein K variable-temperature digestion and high-concentration potassium acetate purification were applied to optimize the high-concentration-salt precipitation method, and then the optimized method was compared with two common extraction methods, the sucrose density gradient centrifugation method and traditional high-concentration-salt precipitation method. The mtDNA samples were identified by using spectrophotometry, agarose gel electrophoresis and the amplification products of COX1. The nuclear DNA contamination was tested by the amplification products of ITS. RESULTS: The concentration and yield of the improved method was significantly higher than those of the traditional method (F = 3 032.65, 10 185.00, both P < 0.01). The mtDNA samples extracted were essentially free of nuclear DNA and protein, meeting PCR, sequence analysis and other molecular biology research requirements. CONCLUSIONS: The improved high-concentration-salt precipitation method for isolating mtDNA is simple, and it has high yield and low cost. The extracted mtDNA can meet relevant analysis requirements. PMID- 29469319 TI - [Temporal and spatial distribution of Schistosoma infection of population and its risk factors in Eastern Dongting Lake area in 2012 and 2014]. AB - OBJECTIVE: To investigate the temporal and spatial distribution of Schistosoma infection of population and its risk factors in Eastern Dongting Lake area in 2012 and 2014, so as to provide the reference for formulating effective intervention measures. METHODS: Junshan District was selected as a study field in Eastern Dongting Lake area. The method of spatial autocorrelation analysis was applied to analyze the change of spatial distribution of Schistosoma infection in Junshan District in 2012 and 2014. The spatial regression model was fitted to detect the risk factors for human infection. RESULTS: The livestock infection rate in 2013 was lower than that in 2011. The average infection rate of schistosome was reduced to 0.55% in 2014. The spatial autocorrelation existed on the distribution of schistosomiasis in Junshan District in both 2012 and 2014 and 4 high incidence villages were identified. The results of the spatial error model showed that the prevalence of human infection was positively correlated with the infection rate of the livestock and the area of the susceptible environment in 2012. The spatial lag model showed that the prevalence of human schistosomiasis was positively correlated with the area of the susceptible environment, but not with the infection rate of livestock. CONCLUSIONS: The measures involving grazing prohibition and phasing out cattle and sheep are remarkably effective and should continue on the basis of the current spatial distribution of schistosomiasis in this area.

AB - OBJECTIVE: To investigate the malaria knowledge of CDC staff and their demands on related training in malaria non-endemic areas, so as to provide the reference for planning the appropriate curriculum. METHODS: All the participants who were the staff of county CDCs all over Qinghai Province and attended the provincial training workshop were surveyed. A self-administered questionnaire survey was carried out and the data was statistically analyzed. RESULTS: A total of 115 participants were involved in this survey. They were mostly (85.21%) from county CDCs. The general knowledge of malaria among the respondents was well, and the average rate of correct answers was 70.35%. However, the answers to the general knowledge of malaria and anti-malaria treatment were not well enough. The rates of correct answers were 61.96% and 48.99% respectively. The differences among the groups of job title ranking, department of working and level of CDC were not significant (F = 0.13-2.02, all P > 0.05). The number of correct answers was significantly increased after the training course. The average score after the training was 79.20+/-15.16 while the pre-training score was 70.34+/-17.46 (t = 3.86, P < 0.05), especially in the answers to general malaria knowledge and malaria surveillance and response (t = 4.30, 4.97, both P < 0.05). The general knowledge of malaria was considered as the most need of training as 80% of the respondents voted "Yes", according to the demand analysis. There was no significant difference among the different groups (F = 0.61-3.11, both P > 0.05). CONCLUSIONS: The malaria knowledge is well mastered by the staff of CDCs in Qinghai Province, and the further training courses are requested and addressed in the target areas such as general malaria knowledge, anti-malaria treatment, malaria surveillance and response. PMID- 29469321 TI - [Identification of a myeloid differentiation factor 88 (MyD88) in Oncomelania hupensis against Schistosoma japonicum infection]. AB - OBJECTIVE: To identify a myeloid differentiation factor 88 (MyD88) in Oncomelania hupensis, and characterize the role of MyD88 against Schistosoma japonicum infection. METHODS: The complete cDNA of MyD88 in O. hupensis was obtained by using rapid amplification of cDNA ends (RACE), and homologues sequences and conserved domains were aligned and the structure of MyD88 was predicted either. A phylogenetic tree of MyD88 was further constructed with other species. In addition, the mRNA expression level of O. hupensis MyD88 before and after S. japonicum infection was investigated by real-time quantitative PCR (RT-qPCR). RESULTS: The cDNA of O. hupensis MyD88 consisted of 1 406 bp open reading frame (ORF), encoding 468 amino acid residues, which contained death domain and Toll/interlrukin-1 receptor (TIR) domain, the typical features of MyD88 family proteins. The predicted amino acid sequence of O. hupensis MyD88 shared 38%-52% identity with other mollusc. O. hupensis MyD88 was phylogenetically closeted to Biomphalaria glabrata MyD88. The O. hupensis MyD88 existed in all selected tissues and expressed highly in hemocyte, up-regulated after S. japonicum infection in all selected tissues except cephalopodium, especially higher in whole snail and hemocyte. CONCLUSIONS: MyD88-dependent signaling pathway is present in O. hupensis and plays an important role in innate immune response against S. japonicum infection.

AB - OBJECTIVE: To assess the risk of secondary transmission induced by imported malaria in Jiangxi Province, so as to provide the evidence for adjustment of malaria surveillance strategies in the key groups and areas. METHODS: The Delphi method was used to establish the secondary transmission risk indicator system and the weight of each index was obtained. The data of malaria prevalence, vector distribution and intervention capacity were collected in 100 counties of Jiangxi Province from 2012 to 2015. The transmission potential index (TPI), intervention capacity index (ICI), and malaria risk index (MRI) were calculated for each county. The risk map was drawn with GIS software. RESULTS: The top ten counties with highly potential risk indicators were Linchuan District (2.131), Xinzhou District (1.609), Jiujiang County (1.404), Zhanggong District (1.365), Fengcheng City (1.225), Qingshanhu District (1.184), Yudu County (1.171), Dingnan County (1.018), Xunyang District (1.015) and Zhushan District (1.006). The high risk areas were mainly distributed in the regions of the capitals of their prefectures and in counties with more floating population. CONCLUSIONS: There are the risk of the secondary transmission induced by imported malaria in Jiangxi Province. The high risk of the secondary transmission is shown in the areas with more floating population and weaker intervention capacity. PMID- 29469323 TI - [Molecular epidemiology of Cryptosporidium infection in infants with diarrhea in Wuhan City]. AB - OBJECTIVE: To understand the prevalence of Cryptosporidium infection in diarrhea infants under 2 years old in Wuhan City, so as to provide the epidemiological evidence for the prevention and treatment of cryptosporidiosis. METHODS: The fecal samples from infants under 2 years old with diarrhea were collected in Hubei General Hospital and Central South Hospital in Wuhan City, Hubei Province from August 2014 to July 2015. The fecal samples were stored in 2.5% potassium dichromate at 4 C after filtered. The DNA was extracted from the fecal pellets with the phenol-chloroform method. The Cryptosporidium species were detected by a nested PCR assay targeting the SSU rRNA gene of the parasite. All the positive PCR products were sequenced on ABI 3100 automated sequencer, and the amplified sequences were compared to homologous sequences in the NCBI database by using the Basic Local Alignment Search Tool (BLAST). Phylogenetic analyses were performed by using the software MEGA (version 4.0) based on the Neighbour-Joining method. RESULTS: The human stool specimens (n = 298) were screened for the presence of Cryptosporidium by nested PCR. The infection rate of Cryptosporidium was 3.02% (9/298). The infection rate of Cryptosporidium was 5.93% (7/118) in the infants between 1-2 years old, and the infection rate was 1.11% (2/180) in the infants under 1 year old, and there was a significant difference between the two groups (chi2 = 4.13, P < 0.05). The nine samples which were positive by nested PCR were successfully sequenced and compared with the reference sequences in GenBank. The results revealed the nine positive specimens were all infected with C. parvum, and two of them were co-infected with C. hominis. Neighbor-joining trees were constructed from the aligned partial SSU rRNA sequences of these nine isolates, and in the SSU rRNA locus, the nine isolates were grouped with C. parvum. CONCLUSIONS: There exists Cryptosporidium infection in the infants under 2 years old with diarrhea in Wuhan City, and the main species of Cryptosporidium is C. parvum. PMID- 29469324 TI - [Changes of liver fibrosis-related miRNAs induced by soluble egg antigen of Schistosoma japonicum]. AB - OBJECTIVE: To investigate the expression of miRNA associated with hepatic fibrosis induced by Schistosoma japonicum soluble egg antigen stimulation in mouse hepatocytes (AML12), so as to lay the foundation for clarifying the mechanism of schistosome infection leading to hepatic fibrosis. METHODS: The expressions of miR-122, miR-182, miR-23b, miR27b and KSRP in AML12 cells treated with SEA were measured by q-PCR. KSRP protein in cell lyses was measured by Western blotting. AML12 cells were transfected with miR-27b precursor or anti-miR 27b for 24 h, then q-PCR was adopted to determine KSRP mRNA, and KSRP protein was detected by Western blotting. RESULTS: The expressions of miR-182, miR-23b and miR27b were decreased and miR-122 was increased in AML12 cells following SEA treatment (all P < 0.05). An increase of mRNA and protein of KSRP expression was also observed in AML12 cells after SEA stimulation (both P < 0.05). In addition, KSRP mRNA expression was not changed significantly in AML12 cells transfected with anti-miR-27b or miR-27b precursor, and miR27b precursor reduced KSRP protein expression as compared with the control. In contrast, the expression of KSRP protein was increased in the anti-miR-27b group and decreased in the miR-27b precursor group. CONCLUSIONS: After the stimulation of SEA, the expressions of a variety of liver fibrosis-related miRNAs and KSRP change in murine hepatocytes, including miR-27b. And miR-27b can regulate the expression of KSRP. These findings might lay a foundation for further study on the molecular mechanism of fibrosis induced by schistosome infection.

AB - OBJECTIVE: To understand the present situation and requirements of health education in schistosomiasis control in Hubei Province, so as to improve the health education to the targeted people. METHODS: Through the questionnaire survey and field investigation, the data of the present situation and requirements of health education in schistosomiasis control were collected in 24 counties (cities) of Hubei Province, and these data included the related institution structure of health education, basic information of personnel, equipment, funds, and health education working form. All the data collected were analyzed and evaluated. RESULTS: Among the 24 counties, there were 12 independent departments of health education, accounting for 50%. In terms of the basic information of the health education staff, the youngest person was 34 years old and the eldest was 58 years old, and the mean age was 46.55+/- 6.9 years. For the formal school education of the staff, 5 had senior high school or below education (20.8%), 16 had college education (66.7%), 3 had bachelor degree or above (12.5%). There were 10 counties (41.70%) with the special funds for health education work but there were 3 counties (12.50%) without the special funds. CONCLUSIONS: The effectiveness of health education work in schistosomiasis control is remarkable, but there are still deficiencies in professional staff and funds in Hubei Province. PMID- 29469327 TI - [Infection situation of intestinal nematodes and knowledge about prevention and control of intestinal nematodiasis in Jingjiang City]. AB - OBJECTIVE: To investigate the infection situation of intestinal nematodes and knowledge about the prevention and control of intestinal nematodiasis, so as to explore the effective control measures in Jingjiang City. METHODS: The towns where more floating people lived were randomly selected and the infection situation of intestinal nematodes was investigated with KatoKatz method, and the residents'awareness of the prevention and control of nematodiasis was surveyed with questionnaires. RESULTS: From 2013 to 2015, totally 4 555 local residents and 2 278 floating people were investigated in Jingjiang City. The infection rate of intestinal nematodes was 0.29% (13 cases) in the local people, while the rate was 0.75% (17 cases) in the floating people, and the difference was significant (chi2 = 7.380, P < 0.01). The differences of the intestinal nematode infection rates between sexes in both local residents and floating people were not significant (chi2 = 0.010, 0.048, both P > 0.05). The awareness rate of intestinal nematodiasis prevention and control of the local residents was significantly higher than that of the floating people (chi2 = 9.649-164.533, all P < 0.01). CONCLUSIONS: The floating people is the focus of intestinal nematodiasis control, and the health education of ancylostomiasis control should be strengthened in Jingjiang City.

AB - OBJECTIVE: To carry out the surveillance with sentinel mice in the key water areas of schistosomiasis endemic regions in Yunnan Province, so as to establish and perfect the surveillance and forecast system of schistosomiasis. METHODS: Six villages of three counties with schistosomiasis heavy endemic status were selected as the survey points. Then, the surveillance and forecast with the sentinel mice were carried out in the key water areas in the survey points. The recovered sentinel mice were dissected in laboratory, and their serum antibodies against schistosome were detected. Meanwhile, the suspicious infested water contacts of the residents and livestock in the surveillance sites were investigated, and the endemic data of schistosomiasis in the survey points in recent 3 years were collected and analyzed. RESULTS: Totally 282 sentinel mice were placed in the water area, 252 were recovered, with a recovery rate of 90.78%, and 8 mice were dead, with a mortality rate of 3.13%. The number of mice with schistosome egg granuloma and adult worm detected were both 0, and the worm burden and the positive rate of serum antibodies against schistosome were both 0, too. The persons who contacted with the suspicious infested water were mainly villagers and students by harvesting and playing. The Oncomelania hupensis snail areas, the infection rates of residents and livestock were obviously declined in recent 3 years. CONCLUSIONS: There are no positive sentinel mice found in the key water areas of the surveillance sites in Yunnan Province, which suggests that the schistosome infection risk of residents and livestock is low. However, the comprehensive control measures, surveillance and forecast with sentinel mice in the key water areas of schistosomiasis endemic regions still should be strengthened.

AB - OBJECTIVE: To understand the status of Toxoplasma gondii infection in women with adverse pregnancy outcomes in Longhua region, Hebei Province. METHODS: A total of 393 women with adverse pregnancy outcomes were chosen as respondents in the Longhua County Maternal and Child Health Care Center between January 2013 and June 2016 and were divided into an acute infection group, a previous infection group, and an active infection group according to the test results. Totally 256 women without adverse pregnancy outcomes were selected as a control group. IgM and IgG antibodies to T. gondii were detected by using ELISA in each group. The risk factors of T. gondii infection were surveyed by questionnaires. RESULTS: The T. gondii infection rate of the women with adverse pregnancy outcomes was 27.23% (107/393), which was significantly higher than 8.20% (21/ 256) in the control group (chi2 = 35.46, P<0.01). The rates of acute infection, previous infection, active infection in the women with adverse pregnancy outcomes were 6.87% (27/393), 18.58% (73/393), and 2.54% (10/393) respectively, which was significantly higher than those[1.17% (3/256), 7.03% (18/256), 0 (0/256) ]in the control group (chi2 = 11.43, 17.15, 7.90 respectively, P<0.01). The ratios of the career in contact with raw meat, feeding pets (dog and cat), tasting raw meat, chopping board regardless of uncooked or cooked food, frequently eating rinsing boiler or barbecue, frequently eating outside of the women with T. gondii infection were significantly higher than those of the women without T. gondii infection (chi2 =12.08, 29.23, 8.55, 13.41, 7.28, 6.06 respectively, P < 0.01 or 0.05). CONCLUSIONS: T. gondii infection could lead to serious adverse pregnancy outcomes. Therefore, to avoid contacting with pets, not eating undercooked food, and strengthening personal health protection are the important keys to avoid T. gondii infection. PMID- 29469331 TI - [Knowledge, attitude and practice related to schistosomiasis control among rural residents in Wanjiang River region after a flood]. AB - OBJECTIVE: To investigate the status of knowledge, attitude and behavior of schistosomiasis control of rural residents in Wanjiang River region after a flood, so as to provide the reference for targeted health education. METHODS: The multistage sampling was applied to select the respondents in rural residents in Wanjiang River region, and the self-designed questionnaire was used to investigate the current situation of knowledge, attitude and behavior of schistosomiasis prevention and control of the rural residents. RESULTS: The total awareness rate of knowledge about the prevention and control of schistosomiasis was 47.92%. The age, education, family income, relatives and friends with medical background, and health education significantly influenced the awareness rate (chi2 = 12.76, 89.19, 18.19, 50.83 and 92.60 respectively, all P < 0.05). The accuracy rates of attitude and behavior in schistosomiasis control were 62.89% and 52.37% respectively. CONCLUSIONS: The awareness rate of knowledge about the prevention and control of schistosomiasis, and the accuracy rates of attitude and behavior in schistosomiasis control of the rural residents in Wanjiang River region are all inefficient, and therefore, the targeted health education should be strengthened to decrease the risk of schistosomiasis transmission. PMID- 29469332 TI - [Analysis of antibody titer value of IHA in 135 acute schistosomiasis patients]. AB - OBJECTIVE: To analyze the antibody titer value of indirect haemagglutination test (IHA) in 135 confirmed acute schistosomiasis patients, so as to provide the evidence for improving the diagnosis and treatment of acute schistosomiasis. METHODS: A total of 135 acute schistosomiasis inpatients were selected from 2001 to 2006. They all received the IHA antibody titer detection, and the correlation among the age, incubation period, and hospitalization days was calculated. RESULTS: The antibody titers of IHA were higher than 1:320 in all the cases. The percentages of 1:640, 1:1 280, 1:2 560, 1:5 120 and 1:10 240 were 1.48%, 28.15%, 35.56%, 20.00%, and 14.81% respectively. The mean age was (47.70 +/- 14.58) years, average incubation period was (38.03 +/- 4.59) days and mean hospital stay time was (15.08 +/- 3.79) days. The antibody titer value had no correlation with the age distribution (r = 0.109, P > 0.05). There was a negatively correlation between the antibody titer value and incubation period, (r = -0.558, P <0.01), there was a positive correlation between the antibody titer value and hospitalization time (r = 0.791, P < 0.01), and there were significant differences among different groups (F = 17.07, 64.53, both P < 0.01). CONCLUSIONS: The antibody titer of acute schistosomiasis cases detected by IHA is 1:640 and above. There is no correlation between the antibody titer value and age, but the antibody titer value is higher, the incubation period is shorter and hospitalization time is longer.

AB - Clonorchis sinensis infection is carcinogenic to human, which results in cholangiocarcinoma, confirmed by the World Health Organization. An investigation in 2005 indicated that the standardized C. sinensis infection rate was 0.58%, with 12 490 000 infected people estimated in the clonorchiasis endemic areas in China. In the world, 80% of C. sinensis infected people were distributed in China. Diagnostic Criteria for Clonorchiasis (WS309-2009) was compiled by the ex Ministry of Health of the People's Republic of China and it was issued and implemented in March 13, 2009. The Diagnostic Criteria for Clonorchiasis is composed of six chapters, including the Range of Application, Terms and Definitions, Diagnostic Basis, Diagnostic Principle, Diagnostic Standard, and Differential Diagnosis. Three informative appendices (etiology, epidemiology, clinical manifestation; enzyme-linked immunosorbent assay; differential diagnosis) and one normative appendix (laboratory examination) are appended. The Criteria provides the technical reference for diagnosis of clonorchiasis in medical institutions and disease control institutions. Combined with the current epidemic situation of clonorchiasis in China, this paper interprets the main contents of the Diagnostic Criteria for Clonorchiasis (WS309-2009), so as to promote its learning and implementing. PMID- 29469344 TI - [Interpretation of Diagnostic Criteria for Kala-azar]. AB - Kala-azar was once transmitted in the northern area of the Yangtze River in China, including 16 provinces (cities or autonomous regions). Through the great continuing prevention and control effort, this disease has been effectively controlled in the most of endemic areas. However, because the epidemic factors of the disease are complex, this disease still transmits or sporadically occurs in the western part of China, including 60 counties of Xinjiang, Gansu, Sichuan, Inner Mongolia, Shanxi, and Shaanxi provinces (autonomous regions). Following the Management Measures for Health Criteria, the Diagnostic Criteria for Kala-azar (WS 258-2006) was compiled by the ex-Ministry of Health of the People's Republic of China and it was issued in April 7, 2006 and implemented in December 1, 2006. The Criteria consists of six parts, including the application range, terms and definitions, diagnostic principle, diagnostic standard, and differential diagnosis. Two informative appendices (epidemiology and differential diagnosis) and two normative appendices (immune-detection and etiological examination) are attached. The Criteria provides the technical reference for diagnosis of kala azar in medical institutions and disease control institutions. Combined with the current epidemic situation of kala-azar in China, this paper interprets the main contents of the Diagnostic Criteria for Kala-azar (WS 258-2006), so as to promote its learning and implementing.

AB - OBJECTIVE: To establish an experimental model of acute cerebral schistosomiasis japonica and explore the MRI manifestations of acute cerebral schistosomiasis. METHODS: Rabbits were divided into 3 groups with 10 rabbits in each group. The rabbits in the experimental group were directly injected with suspension fluid of Schistosoma japonicum eggs (0.9 mg, 1 ml) by the cranial drilling method, those in the negative control group were given saline (1 ml) by the same method above mentioned, and those in the blank control group were not given any treatment. Antibiotic was given to the first two groups after the operation. The clinical manifestations of the 3 groups were observed, and the magnetic resonance imaging (MRI) was performed in 30 days post-operation, and then the brain tissues were taken for pathological examinations. RESULTS: All the rabbits in the experimental group exhibited inappetence, various neurological symptoms including hemiplegia, and weight loss after the operation; while those in the negative control group showed inappetence in 3 days after the operation, and 1 week later, the symptom disappeared; there were no adverse reactions in the blank control group. MRI of the experimental group showed nodular or patchy enhancement on T1WI enhancement, brain edema, abnormal ventricular dilatation, and needle augmentation. SWI displayed hypointense in the abnormal enhanced nodules and flaky hypointense on the operation brain. In the negative control group, 2 rabbits showed abnormal enhancement of the needle canal, and 1 showed mild dilatation of the ventricle. The blank control group showed normal manifestations. The pathological examinations showed abnormal appearances in 10 rabbits of the experimental group, including 6 with S. japonicum egg granuloma nodules, nonspecific granuloma nodules coexisted with perivascular inflammation; no granuloma nodules were found in the negative control group, but 2 rabbits showed vascular inflammation; the blank control group showed the normal brain tissue. CONCLUSIONS: An experimental model of acute cerebral schistosomiasis is successfully established in rabbits by intracranial injection of schistosome eggs. The MRI examination combined with the clinical manifestations can improve the accuracy of early diagnosis of cerebral schistosomiasis.

CONCLUSIONS: The accuracy rates of chronic schistosomiasis patients' attitude and practice on schistosomiasis control in Nanchang City remain low. Therefore, the intensity of attitude and practice intervention should be strengthened in the Poyang Lake District in order to enhance the self-protection awareness of the patients. PMID- 29469351 TI - [Survey of schistosomiasis KAP and influencing factors of behaviors among residents in Jiangsu Province]. AB - OBJECTIVE: To understand the schistosomiasis control knowledge, attitude, and practice (KAP), and influencing factors of behaviors among residents in Jiangsu Province, so as to provide the evidence for making effective health education and health promotion models. METHODS: The probability proportionate to size sampling (PPS) and multi-stage sampling methods were adopted to sample the research objects. A questionnaire survey of schistosomiasis control KAP was conducted in the residents of 16 to 69 years old in schistosomiasis endemic areas of Jiangsu Province, and the results were statistically analyzed. RESULTS: The total awareness rate of the participants was 95.98% for schistosomiasis control knowledge. The correct rates of attitude and practice were 89.06% and 77.43%, respectively. The awareness/correct rates of knowledge, attitude and practice reduced in turns significantly (chi2 =1 282.96, P < 0.01). The knowledge awareness rate of fishermen and boatmen was 90.98%, but their attitude correct rate was only 53.81% ( chi2 =120.52, P < 0.01). The unconditional logistic regression analysis showed that with the education level increasing, their practice correct rate rose, and the participants with the college degree or above had a higher correct rate compared to illeterate ones (OR = 6.411, 95% CI: 4.896 8.395). The practice correct rate of the fisher-men and boatmen was only 5.1% of the rate of the farmers (OR = 0.051, 95% CI: 0.029-0.091). CONCLUSIONS: The total awareness rate of basic knowledge of schistosomiasis prevention and control in the residents of Jiangsu Province has reached the requirements in the "National Schistosomiasis Control Long-term Planning Outline (2004-2015)", but the correct rate of behaviors is low. The education level, occupation and residential areas affect the health behaviors of schistosomiasis prevention and control. Therefore, it is necessary to carry out targeted health promotion activities to promote the formation of healthy lifestyle and behaviors. PMID- 29469352 TI - [Survey of epidemic status of paragonimiasis in western mountainous areas in Hubei Province]. AB - OBJECTIVE: To understand the current status of paragonimiasis epidemic in western mountain areas in Hubei Province. METHODS: Four counties (cities) of Western Hubei Province (Xingshan, Enshi, Yunxi, Baokang) were selected as the investigation sites for active surveillance. Crabs were captured and the metacercariae of Paragonimus were detected. Meanwhile, the blood samples were collected from the residents in the surveillance sites and the unique IgG and IgM antibodies against Paragonimus in the sera were detected by ELISA. In addition, a questionnaire survey about knowledge and behavior of prevention and control of paragonimiasis was taken among the residents. RESULTS: A total of 1 143 residents were investigated in the active surveillance, the total positive rate of the serology test was 1.84% (21/1 143), while the rates of the male and the female were 1.78% (10/562) and 1.89% (11/581), respectively, with no statistical significance between them ( chi2 = 0.002, P > 0.05). The average weight of 161 fresh-water crabs captured was 11.72 g, with the positive rate of 9.32% (15/161) and the infective density of 7.07 metacercariae per positive crab. The positive rates of the male and female crabs were 11.54% (9/78) and 7.23% (6/83), respectively ( chi2 = 0.884, P > 0.05), and the infective densities were 6.67 and 7.67 metacercariae per positive crab, respectively. Totally 1 143 residents were investigated by questionnaires, and 0.44% of them had the behavior of eating raw or half-done fresh-water crab, and 0.87% of them had the behavior of drinking un boiled stream water. CONCLUSIONS: The transmission chain of paragonimiasis still exists in the nature environment of mountain area in Western Hubei Province. The positive rate of the second intermediate host rebounds in some investigation sites. Therefore, the measures of continuous surveillance and health education should be taken to avoid the appearance of the prevalence or outbreak. PMID- 29469353 TI - [Monitoring results of soil-transmitted nematodiasis in national surveillance site of Huaiyang County in Henan Province, 2006-2015]. AB - OBJECTIVE: To understand the epidemic situation of soil-transmitted nematodiasis in the national surveillance site in Henan Province. METHODS: Over 1 000 fecal samples from inhabitants in Huaiyang County of Henan Province, which was a national surveillance site, were collected each year from 2006 to 2015, the eggs of soil-transmitted nematodes and other intestinal helminths were examined by Kato-Kats technique. The cellophane swab method was used to detect Enterobius vermicularis eggs in children aged 3 to 12 years. In addition, the soil samples were collected from vegetable fields, lavatories, courtyards and kitchens of 10 families randomly selected in each year to examine Ascaris eggs by a modified saturated sodium nitrate floatation method. RESULTS: From 2006 to 2015, 10 419 persons were investigated, and the eggs of five species of intestinal helminths, Ascaris lumbricoides, Trichuris trichiura, hookworm, E. vermicularis, and Trichostrongylus orientalis, were detected, The average infection rate of soil transmitted nematodes in residents in Huaiyang County was 3.69%. The intensity of infection was mild and a family clustering was obvious. Both the infection rates of E. vermicularis in children and soil-transmitted nematodes in villagers had no significant differences between different genders (both P>0.05). The infection rates of soil-transmitted nematodes, A. lumbricoides and E. vermicularis all reached the highest in the age group of 1-10 years. For different education back ground, the people with primary school education had the highest infection rate, and the infection rate showed a decreasing trend with the increase of the educational level. The infection rate of soil-transmitted nematodes in the national surveillance site in Henan Province showed a decreasing trend from 2006 to 2015. Unfertilized and fertilized A. lumbricoides eggs were detected in the soil samples, but the positive rate was very low. CONCLUSIONS: In the recent 10 years, the infection rate of soil-transmitted nematodes in the national surveillance site in Henan Province shows a decreasing trend and maintains at a low level. The infection shows a family clustering. The children, especially those aged 3-9 years are the main infected population, and E. vermicularis infection is the key point of prevention and control.

The infection rates of overall parasites, helminthes and protozoans were respectively 1.65%, 1.07% and 0.61%. The infection rate of T. trichiura in the children aged 3 to 6 years was 3.79%. Only 0.10 percent of the infections were co-infection, and all were infected by 2 kinds of parasites. The principal parasites in this district were Ascaris lumbricoides (0.31%), Blastocystis hominis (0.28%) and hookworm (0.27%). The T. trichiura infection rate among children was 3.79% by the cellophane swab method. The infections of protozoans were found in all age groups. In the group aged 9 years and below, the maximum kinds of parasites were found. CONCLUSIONS: The infection rates of principal human parasites in Huaiyang hilly ecological region of Henan have decreased sharply, but more efforts still should be paid on the prevention and control of parasitosis in children.

AB - OBJECTIVE: To investigate the risk factors of schistosomiasis transmission in Jingmen City. METHODS: The Oncomelania hupensis snails, the wild animal feces, and infection source were selected as the monitoring objects to carry out the schistosomiasis risk monitoring. I-III levels of risk environments were treated with appropriate measures. RESULTS: A total of 52 environments and three water systems were monitored and 1 542 snails were dissected but no Schistosoma infected snails were found. Nine fecal samples were collected from the areas with snails, and no eggs of Schistosoma were found. Eighty-nine samples of cattle/sheep faces, and mice and dogs were collected, and three samples of cattle feces were found with Schistosoma eggs. Five environments were assessed as Grade II, and 48 environments were assessed as Grade III, and 2 environments were assessed as no risk of schistosomiasis transmission. CONCLUSIONS: In Jingmen City, the mollusciciding work from May to June could decrease the density of snails and the risk of schistosomiasis transmission efficiently. The schistosome infected cattle were the main infection source, and therefore, the cattle and snails should be administrated simultaneously.

AB - OBJECTIVE: To evaluate the effect of schistosomiasis control and prevention in Yangxin County from 2004 to 2015, so as to provide the evidence for improving the work of schistosomiasis transmission interrupted and elimination in the future. METHODS: According to the endemic types and endemic regularity of schistosomiasis in Yangxin County, the comprehensive control strategies were adopted, and the programs related to sanitation, water conservancy, forestry, and agriculture were implemented continuously. The schistosomiasis control effects in this county from 2004 to 2015 were analyzed and compared. RESULTS: After the implementation of the schistosomiasis comprehensive control strategies in Yangxin County, the calculated number of patients reduced from 22 240 in 2004 to 1 471 in 2015, the infection rate of residents reduced from 8.57% in 2004 to 0.16% in 2015, the number of patients with acute schistosome infection reduced from 64 in 2004 to 0, and no cases of acute schistosomiasis found since 2009. The infection rate of cattle decreased from 8.87% in 2004 to 0. The area with Oncomelania hupensis snails and the area of susceptible zone reduced from 3 446.21 hm2 and 1 111.59 hm2 in 2004 to 2 285.75 hm2 and 41.28 hm2 in 2015 respectively, and the schistosome-infection rate of snails reduced from 0.76% in 2004 to 0. CONCLUSIONS: Since the comprehensive control strategy implemented from 2004, the endemic situation of schistosomiasis in Yangxin County has decreased significantly. However, the harness force of the Fu River as well as the control of infection source of livestock still should be strengthened to consolidate the control achievement.

AB - OBJECTIVE: To analyze the results of malaria focus investigation and disposal in Tengchong City, Yunnan Province between 2015 and 2016, so as to provide evidences for interrupting potential malaria transmission. METHODS: The malaria foci were investigated and disposed according to the malaria cases reported from "China Information System for Disease Control and Prevention" in Tengchong City between 2015 and 2016. The mosquitoes were captured by mosquito-lured lamp overnight to investigate the malaria vector in local. The peripheral blood samples were collected from the local residents with a febrile history in the foci within two weeks and the accompanists of the cases, and then the rapid malaria diagnosis tests were used to screen the malaria carriers. RESULTS: Totally 145 imported malaria cases were reported in Tengchong City between 2015 and 2016, and the focus investigation and disposal rate within 7 d was 100% (145/145). A total of 16 186 mosquitoes of 12 species of Anopheles were captured, among which An. sinensis was the predominant, accounting for 64.31% (10 410/16 186), followed by An. kunmingensis and An. minimus, with the constituent ratios of 14.15% (2 291/16 186) and 11.66% (1 887/16 186), respectively. One person (1.96%, 1/51) in the 51 accompanists of the cases was positive in the malaria rapid diagnosis test. CONCLUSIONS: The malaria transmission vectors such as An. sinensis, An. kunmingensis, An. minimus etc. are still distributed in Tengchong City, and An. sinensis is the predominant species. Therefore, the relevant authorities should continue to strengthen the focus investigation and disposal to interrupt the potential introduced malaria transmission by imported cases in the future.

AB - OBJECTIVE: To understand the situation and epidemic characteristics of imported falciparum malaria in Huai'an City from 2010 to 2016, so as to provide the evidence for formulating the prevention and control strategies of imported falciparum malaria in the city. METHODS: The epidemic data of imported falciparum malaria in Huai'an City from 2010 to 2016 were analyzed by using the descriptive epidemiological method. RESULTS: A total of 308 malaria cases were reported in Huai'an City from 2010 to 2016 with the average annual incidence of 0.88/105. A total of 240 imported falciparum malaria cases were reported, of which 18 cases (7.50%) developed into severe illness, and 2 severe patients died. The cases were reported in every county (district), and the incidence rates of Qingpu District and Huai'an District were higher than the city average level. The cases occurred every month, so there was no significant seasonal variation in the reporting time of the cases. Most of the patients were young men and aged 30-49 years. The occupational distribution revealed that the patients were mainly farmers, workers and migrant workers. The main source of infection was from African countries. The median interval from symptom appearing to definite diagnosis was 1 day, and the longest interval was 236 days. Twenty-nine cases were diagnosed within 24 hours, accounting for 12.08%. CONCLUSIONS: The epidemic situation of imported falciparum malaria in Huai'an City is grim. In order to consolidate the achievements of malaria eradication, it is necessary to further improve the multi-sectoral cooperation mechanism, strengthen the management of floating population and take effective measures to reduce the risk of imported falciparum malaria.

AB - OBJECTIVE: To analyze the epidemiological situation of human intestinal nematode infections in Nanjing City from 2006 to 2015, so as to provide the reference for formulating prevention and control measures. METHODS: The surveillance data of human intestinal nematode infections in Nanjing City from 2006 to 2015 were collected and analyzed statistically. RESULTS: From 2006 to 2015, 98 804 person times of residents were surveyed in Nanjing City, and 465 person-times of residents were detected with intestinal nematode infections. The highest infection rate was in 2006 (1.97%), and the lowest in 2013 and 2015 (both 0.05%). Moreover, the positive rate of human intestinal nematode infections showed a significantly declining trend in total ( chi2 = 552.19, P < 0.001). Meanwhile, the numbers of Ascaris lumbricoides, hookworm and Trichuris trichura cases were 329, 98 and 25 respectively, and the infection rates were 0.33%, 0.10% and 0.03% respectively. Among them, 443 cases had mild infection intensity (98.66%). There were 462 cases of single-infection (99.35%), and 3 of co-infection of two parasites (0.65%). From 2006 to 2015, 92 539 person-times of children under 12 years old were surveyed for Enterobius vermicularis infection and 352 cases were detected with E. vermicularis infection. Moreover, the positive rate showed a significantly decreasing trend in total (chi2 = 147.94, P <0.001). CONCLUSIONS: The control effect of human intestinal nematode infections in Nanjing City is remarkable. However, the surveillance and health education in key groups still should be strengthened, and the prevention and control programs should be adjusted promptly to further consolidating the effectiveness of intestinal nematode disease prevention and control. PMID- 29469368 TI - [Survey of human major parasitic diseases in Shixing County from 2002 to 2016]. AB - OBJECTIVE: To analyze the results of 3 investigations (2002-2004, 2008-2009, and 2016) of major parasitic diseases in Shixing County, so as to provide the evidence for formulating further control strategies. METHODS: With the stratified cluster sampling method, 5 administrative villages were investigated. A total of 200 residents aged above 3 years were sampled in each village to investigate the eggs of soil-transmitted nematodes with Kato-Katz technique, and the swab method was applied for detecting the eggs of Enterobius vermicularis in children aged 3 9 years. chi2 test was used for statistical analysis. RESULTS: Totally 3 857 individuals were surveyed for intestinal parasites, and 5 species of parasites were found and the total infection rates were 28.37%, 4.32% and 0.50% in the 3 investigations respectively, and there were statistically significant differences between any two investigations ( chi2 = 287.64, 327.60 and 31.89 respectively, and all P< 0.01). The infection rates of Ascaris lumbricoides, hookworm, Trichuris trichiura and Clonorchis sinensis significantly decreased in the third investigation compared with those in the first investigation ( chi2 = 424.55, 55.45, 43.40 and 26.12 respectively, all P< 0.01). However, there was no significant difference between the E. vermicularis infection rates of the first investigation and the third investigation ( chi2 =0.16, P >0.05). CONCLUSIONS: Compared with the status in the first investigation, the infection rates of A. lumbricoides, hookworm, T. trichiura and C. sinensis are significantly decreased by 90% or more in the third investigation. However, the children's infection rate of E. vermicularis is still very high. Therefore, we should focus on the comprehensive control measures of E. vermicularis infection while formulating further control strategies of parasitic diseases.

AB - OBJECTIVE: To investigate the clinical therapeutic effect of biological information infrared liver therapeutic apparatus (BILT) combined with praziquantel in the treatment of patients with chronic schistosomiasis. METHODS: A case-control study was conducted. A total of 142 chronic schistosomiasis patients were divided into an experimental group (BILT combined with praziquantel) with 64 cases and a control group (routine treatment with praziquantel alone) with 78 cases on the basis of the age, gender, disease duration and liver function as paired condition. Fatigue, diarrhea, abdominal distension, liver function, hyaluronic acid (HA) and laminin (LN) were as observation indexes and the observation results were compared between two groups. RESULTS: Before the treatment, there were no significant differences between the two groups in the indexes above-mentioned (P > 0.05). After the treatment, the incidence rates of fatigue, diarrhea, abdominal distension, abnormal liver function, and the levels of HA and LN in the experimental group were significantly lower than those in the control group (P < 0.01). CONCLUSIONS: BILT combined with praziquantel can significantly alleviate the short-term clinical symptoms, restore liver function and also alleviate hepatic fibrosis of the patients with chronic schistosomiasis.

AB - OBJECTIVE: To evaluate the effects of the project of ditching for drain on Oncomelania hupensis snail control and flood prevention security and explore the optimal engineering design plan in Dongting Lake region. METHODS: A retrospective study was performed on the previous studies about the project of ditching for drain. The reference values of project indices were determined. The outside levee of Nanhu New Distinct of Yueyang City in Dongting Lake region was selected as the study area, and the cross section of marshland perpendicular to the center line of the levee was extracted to research. According to the situations of various water levels, a dynamic simulation was performed on the effect and security of the project of ditching for drain through the software FLAC3D. RESULTS: The retrospective study showed that the project would be effective when the relatively subsoil water level decreased by 0.35 m, and the soil water content decreased correspondingly. The dynamic simulation by FLAC3D showed that the minimum safe distances between transverse ditch 1, vertical ditch and levee toe should be 25 m and 13 m respectively. The digging depth of transverse ditch and vertical ditch should be 1.2 m and 1.0 m respectively. If the width of marshland in drought period was less than 500 m, one transverse ditch was efficient. Otherwise, more transverse ditches should be set with the intervals of 300 m. CONCLUSIONS: The project of ditching for drain is an effective ecological snail elimination method. Optimizing the digging depth of ditches and distances between transverse ditches, vertical ditch and levee toe will ensure the effects and security of the project. PMID- 29469379 TI - [Maximum entropy model versus remote sensing-based methods for extracting Oncomelania hupensis snail habitats]. AB - OBJECTIVE: To explore the technique of maximum entropy model for extracting Oncomelania hupensis snail habitats in Poyang Lake zone. METHODS: The information of snail habitats and related environment factors collected in Poyang Lake zone were integrated to set up the maximum entropy based species model and generate snail habitats distribution map. Two Landsat 7 ETM+ remote sensing images of both wet and drought seasons in Poyang Lake zone were obtained, where the two indices of modified normalized difference water index (MNDWI) and normalized difference vegetation index (NDVI) were applied to extract snail habitats. The ROC curve, sensitivities and specificities were applied to assess their results. Furthermore, the importance of the variables for snail habitats was analyzed by using Jackknife approach. RESULTS: The evaluation results showed that the area under receiver operating characteristic curve (AUC) of testing data by the remote sensing-based method was only 0.56, and the sensitivity and specificity were 0.23 and 0.89 respectively. Nevertheless, those indices above-mentioned of maximum entropy model were 0.876, 0.89 and 0.74 respectively. The main concentration of snail habitats in Poyang Lake zone covered the northeast part of Yongxiu County, northwest of Yugan County, southwest of Poyang County and middle of Xinjian County, and the elevation was the most important environment variable affecting the distribution of snails, and the next was land surface temperature (LST). CONCLUSIONS: The maximum entropy model is more reliable and accurate than the remote sensing-based method for the sake of extracting snail habitats, which has certain guiding significance for the relevant departments to carry out measures to prevent and control high-risk snail habitats.

AB - OBJECTIVE: To understand the geographical features of malaria in Yunnan Province, so as to provide the reference for malaria elimination. METHODS: The data of malaria in Yunnan Province from 2012 to 2015 were collected and analyzed. RESULTS: Totally 2 586 malaria cases were reported in Yunnan Province from 2012 to 2015, in which 274 (10.60%) were local cases and 2 311 (89.37%) were abroad imported, and one (0.03%) was domestic imported. The imported malaria cases and local cases were analyzed according to the sources and locations respectively, and the arithmetic means of the numbers of imported and local cases were 96.29 and 10.96 respectively, the standard deviations of the numbers of imported and local cases were 421.18 and 19.12 respectively, and the difference of the means was not significant (Z = - 0.326, P > 0.10). Both the imported and local malaria cases could be clustered into five sections by the number of 5. The Herfendal Hirshman indexes of the imported and local malaria cases were 8 121 and 1 598 respectively. CONCLUSIONS: There is no significant difference of the distribution between the imported and local malaria cases, and they should be attaching equal importance. The non-uniform degree of imported cases is higher than that of the local cases, while both of them could be divided into five major clusters in the prevention and control work. PMID- 29469382 TI - [Establishment of malaria early warning system in Jiangsu Province VIII Malaria vector monitoring in Jiangsu Province]. AB - OBJECTIVE: To understand the population, density, seasonal fluctuation and nocturnal pattern of malaria vectors in Jiangsu Province, thus to provide evidences for malaria elimination in this province. METHODS: Seven counties (cities, districts) were selected as the monitoring sites for malaria vectors in Jiangsu Province from 2013 to 2015. The mosquitoes were captured by human bait trapping in bed nets and mosquito-lured lamp overnight, and the seasonal fluctuation and nocturnal pattern of malaria vectors were observed. RESULTS: A total of 11 041 Anopheles sinensis mosquitoes were captured by the mosquito-lured lamps in 7 counties of Jiangsu Province from 2013 to 2015, and no An. anthropophagous was found. Among all the 7 monitoring sites, the number of An. sinensis captured in Sihong County was the most (6 742 mosquitoes), while that in Xuyu County was the least (34 mosquitoes). During this period, the density peaks of An. sinensis were the first half of July, the first half of August and the second half of July. A total of 2 421 An. sinensis were collected in 7 monitoring sites from 2013 to 2015 by human bait trapping in bed nets overnight. Among all the 7 monitoring sites, the captured number of An. sinensis in Sihong County was the most (1 085 mosquitoes), while that in Ganyu County was the least (13 mosquitoes). The nocturnal peak of An. sinensis was from 19:00 to 20:00 and 525 An. sinensis mosquitoes were captured during this period of time, which accounted for 21.68% of the total. Hereafter, the captured number of An. sinensis reduced over time. CONCLUSIONS: The density of An. sinensis mosquitoes is still high in individual areas in Jiangsu Province, so the epidemic and vector monitoring still should be strengthened to prevent the local transmission of imported malaria.

The malaria incidence of local residents was reduced to 3.61/100 000 in 1979 and no local malaria case was found since. The imported malaria cases were found in Wuzhou City since 1980, and were more than local cases since 1981. In recent five years, 87.50% (7/8) of imported malaria cases were from south-east Asia. CONCLUSIONS: Wuzhou City has reached the national criterion of malaria elimination, but the imported malaria is the recent threat. The surveillance and control work of malaria should be strengthened.

AB - OBJECTIVE: To analyze the genotypes and homology of MSP-1 and CSP gene of Plasmodium vivax in Shandong Province, so as to provide the evidence for case traceability. METHODS: A total of 12 blood samples were collected from P. vivax infected cases in Shandong Province in 2011. Parasite genomic DNA was extracted. Primers were designed according to MSP-1 and CSP gene sequences of P. vivax. Then Nested PCR, enzyme digestion, sequencing and sequence alignment, and homologous analysis were performed. RESULTS: The MSP-1 gene of all the 12 samples from P. vivax-infected cases were detected with a 470 bp PCR amplification band, and 350 bp and 120 bp enzyme digestion fragments, which were identified as type Sal-1. An analysis of phylogenetic tree of MSP-1 gene showed that the sequences of 9 indigenous case samples in Shandong Province were located in the same branch, one case sample infected from India was located in the same branch with India strains. All the 12 P. vivax-infected samples covered GDRA (D/A) GQPA sequences in CSP gene, which were identified as type PV-I. Of the CSP gene among 12 P. vivax-infected samples, 10 samples of indigenous case in Shandong Province and one sample of the case infected in Guangdong Province were detected with both 560 840 bp and 150-230 bp PCR amplification bands, which were identified as temperate zone family strain of type PV-I. However, one sample from the case infected in India was detected only with a 560-840 bp band, which was identified as tropical zone family strain of PV-I. An analysis of phylogenetic tree of CSP gene showed that the sequences of 10 samples from the indigenous cases in Shandong Province and one sample from the case infected in Guangdong Province were located in the same branch, one sample from the case infected in India was located in the same branch with India and Indonesia strains. CONCLUSIONS: Of all the indigenous isolates in Shandong Province, MSP-1 gene is genotyped type Sal-1, CSP gene is genotyped temperate zone family strain of type PV-I, with a high homology found among the indigenous isolates.

METHODS: A survey was performed according to the scheme of the 3rd Principal Human Parasites of Jiangxi Province. Based on the ecological regions, a stratified cluster sampling method was applied by the economic and geographic situation. In rural areas, the investigation of C. sinensis was carried out together with the soil-transmitted helminths investigation, and in the urban areas, the random cluster sampling method was applied for the C. sinensis investigation. There were 92 survey sites from 32 counties. The eggs of C. sinensis in stool were examined by Kato-Katz technique, and health knowledge was also investigated by questionnaires in some people at the same time. RESULTS: A total of 23 606 sample residents were investigated, and 138 were found infected with C. sinensis, with the infection rate of 0.58%. Light infection was found in most of them. Totally 124 C. sinensis infected persons focused in Xinfeng County, and only a few of infected people scattered in the other counties. In Xinfeng County, 851 residents were investigated. Among them, the infected people were found in all the age groups except the 0- year age group. The highest infection rate appeared in the 70- years group (24.00%). The male infection rate was 20.29%, which was higher than that of the female (6.25%), showing a statistically significant difference (P<0.01). The infection rate was highest in the population who received high school or technical secondary school education (31.48%). For the occupation distribution, the infection rate was highest in public officers (39.39%). The questionnaire survey showed that the infection rate in the populations in Xinfeng County who had the history of eating raw fish or raw shrimp was 33.15%. CONCLUSIONS: The distribution of C. sinensis infection presents a regional aggregation in Xinfeng County, but in other areas, the distribution is sporadic. It is necessary to continue to carry out the parasitic disease screening, and in Xinfeng County, it is necessary to strengthen the comprehensive prevention and control intervention. PMID- 29469386 TI - [Effect of exogenous nitric oxide on antioxidants from mice infected with Trichinella spiralis]. AB - OBJECTIVE: To study the effect of exogenous nitric oxide donor sodium nitroprusside (SNP) on antioxidant enzymes activities and lipid peroxidation of mice infected with Trichinella spiralis. METHODS: BALB/c mice were infected with T. spiralis separated by the digestion method. Forty-two days post-infection, the peripheral blood and hepatic tissue from the infected or normal mice were collected. Then 4 groups were set:liver homogenate from infected mice + SNP (Group A), liver homogenate from normal mice + SNP (Group B), peripheral blood from infected mice + SNP (Group C), and peripheral blood from normal mice + SNP (Group D). The final concentrations of SNP in each group were set as 0 (blank control), 2, 5, 10 MUmol/L and 30 MUmol/L, respectively. After reacting with SNP at 37 C for 30 min, the superoxide dismutase (SOD), glutathione peroxidase (GSH Px), catalase (CAT) activities, and malondialdehyde (MDA) concentration were examined and compared. RESULTS: The levels of SOD, CAT, GSH-Px and MDA concentration in the liver and the blood from the mice infected with T. spiralis were significantly higher than those of the normal ones (all P < 0.05). When reacted with 10 MUmol/L and 30 MUmol/L SNP, the SOD, GSH-Px, and CAT activities in Group A and B decreased significantly (all P < 0.05), while the liver MDA concentration reacted with 2-30 MUmol/L SNP increased obviously (all P < 0.05). As reacted with 30 MUmol/L SNP, the activities of blood SOD, GSH-Px, and CAT in Group C and D decreased, while the MDA concentration in blood still increased (all P < 0.01). When the SNP concentration was in the range of 2-30 MUmol/L, there were a negative correlation between the SNP concentrations and SOD, GSH-Px, and CAT activities, as well as a positive correlation with the MDA concentration in the liver and blood from the mice infected with T. spiralis (all P < 0.05). CONCLUSIONS: T. spiralis infection could cause oxidative damage to mice, and increase SOD, GSH-Px, and CAT activities. Nitric oxide released from SNP can decrease antioxidase activities, and inhibit the antioxidant capacity of mice infected with T. spiralis.

AB - OBJECTIVE: To understand the epidemic status of alveolar echinococcosis in Tibetan children in south Qinghai Province. METHODS: The imageology and serology methods were applied to investigate the epidemic status of alveolar echinococcosis of elementary school students in Yushu and Guoluo prefectures. RESULTS: Totally 19 629 children were investigated by the portable B ultrasound and 221 children were diagnosed as alveolar echinococcosis with the morbidity of 1.13%. Totally 9 888 were investigated by the indirect ELISA, and the positive rate of serum tests was 12.59% (190/9 888). The total morbidity of alveolar echinococcosis of children in Yushu Prefecture was 0.42% (31/7 454) and it was 1.57% (190/12 175) in Guoluo Prefecture and there was a significant difference between them (chi2 = 53.42, P<0.005). The sero-positive rates of children in Yushu and Guoluo were 4.26% (302/7 081) and 18.56% (1 835/9 888), respectively (chi2 = 765.77, P<0.005). The counties with the highest prevalence of alveolar echinococcosis in children were Dari County (4.31%, 106/2 461) and Banma County (1.92%, 26/1 351) of Guoluo Prefecture, and Chengduo County (1.11%, 18/1 612) of Yushu Prefecture. The total morbidity rates of alveolar echinococcosis of male and female children were 0.91% (91/9 954) and 1.34% (130/12 175) respectively (chi2 = 7.35, P<0.005). The total sero-positive rates of alveolar echinococcosis of male and female children were 12.10% (1 037/8 568) and 13.09% (1 100/8 406) respectively (chi2 = 3.63, P>0.05). The total morbidity of alveolar echinococcosis of children in different age groups was from 1.00% to 1.13%, and there was no significant difference among the age groups (chi2 = 2.73, P>0.05). The P1a type, P1b type and P2 type accounted for 67.76% (145/214), 10.75% (23/214) and 16.36% (35/ 214) respectively among the alveolar echinococcosis patients. The diameters of nidus of 87.38% (187/214) patients were less than 5 cm, and 2.80% (6/214) were more than 10 cm. CONCLUSIONS: The epidemic status of alveolar echinococcosis of Tibetan children in south Qinghai Province is serious, but most of the patients were at early stage of the disease. The screening work of alveolar echinococcosis should be strengthened in Tibetan children, so as to perform the early diagnosis and treatment. PMID- 29469388 TI - [A specific immune therapeutic effect of Der p2 T cell epitope vaccine on asthma mice]. AB - OBJECTIVE: To investigate the specific immune therapeutic effect of the T cell fusion peptide vaccine from group II allergens from Dermatophagoides pteronyssinus (Der p2). METHODS: Thirty mice were randomly divided into three groups, namely a negative control group (a PBS group), positive control group (an asthma group) and protein Der p2 T cell fusion epitope for specific immunotherapy (SIT) group (a Der p2 T group). The extract of house dust mites (HDM) was used to establish the asthmatic models in BALB/c mice, and the PBS group was always used with PBS buffer. Thirty minutes before spray inhalation from 25 to 27 days, the mice of the Der p2 T group were respectively injected subcutaneously with the therapeutic proteins for SIT, then the serum and bronchoalveolar lavage fluid (BALF) were collected. ELISA was used to assay the levels of IFN-gamma, IL-4, and IL-13 in BALF, as well as serum levels of specific IgE and IgG2a. The lung tissue sections were stained with haematoxylin and eosin (H&E) for pathological examinations. RESULTS: The ELISA detection revealed that the number of eosinophil in BALF of the asthmatic mice was (5.57 +/- 0.64)*105/ml, which was significantly higher than that in the PBS group [(0.50 +/-0.30)*105/ml, P < 0.01], the number of eosinophil in the Der p2 T immunotherapy group decreased significantly [(3.45 +/- 0.36)*105/ml, P < 0.01]. The content of IFN-gamma in the PBS group, asthma group and Der p2 T group were (267.00 +/- 21.98), (155.80 +/- 20.53) pg/ml and (234.40 +/- 24.46) pg/ml respectively. Compared with the asthma group, the mice with Der p2 T vaccine specific immune treatment produced a high level of IFN gamma (P < 0.01). The content of IL-4 in the PBS group, asthma group and Der p2 T group were (23.40 +/- 5.96), (53.28 +/- 8.26) pg/ml and (30.00 +/- 5.50) pg/ml respectively. Compared with the asthma group, the content of IL-4 in the mice of the Der p2 T treatment group was significantly lower (P < 0.01). Compared with the asthma group [(308.10 +/- 28.32) pg/ml], the content of IL-13 in BALF of the mice in the Der p2 T treatment group was significantly decreased, which was [(174.50 +/- 25.99) pg/ml, P < 0.01]. The content of IL-13 in the PBS group was (95.99 +/- 31.14) pg/ml. The lung tissue sections showed that the lung inflammation in the p2 T Der group was significantly less than that in the asthma group, and the inflammatory cell infiltration was significantly decreased, and airway epithelial construction remodeled. CONCLUSIONS: The Der p2 T cell fusion epitope, which is as vaccines for specific immunotherapy with asthma models, can alleviate effectively allergic inflammation of airway and lung in the mice, and it may be used as a candidate vaccine for asthma. PMID- 29469389 TI - [Development and effectiveness evaluation of time-resolved fluoroimmunoassay kit for detection of Schistosoma japonicum]. AB - OBJECTIVE: To develop a kit of time-resolved fluoroimmunoassay (TRFIA) for detection of Schistosoma japonicum protein SjP38, and evaluate its effectiveness. METHODS: The anti 9G7 SjP38 monoclonal antibody was used as the capture anti-body coated with 96-hole plate, and the Eu3+ labeled 1A6 monoclonal antibody was used as the detection antibody to establish the TRFIA SjP38 kit. In addition, the accuracy, sensitivity, precision, stability and coincidence rate to pathogenic diagnosis of the kit were evaluated. RESULTS: This established kit possessed high accuracy, wide linear range from 2 to 1 250 ng/ml, high sensitivity with the minimum detectable concentration of 0.14 ng/ml, and good precision (the coefficient variation of the intra- and inter-assay were 3.6% to 4.6% and 5.1% to 6.7%, respectively). The stability tests showed that the reagents could be stable for six months at 4 C, 7 d at 37 C. The positive and negative corresponding rates to the pathogen detection method were 95% and 100% respectively. CONCLUSIONS: All the performance and detection indicators of the kit have reached the requirements of clinical test, but its clinical application still needs further validation. PMID- 29469390 TI - [Analysis of coagulation related parameters between patients with advanced schistosomiasis cirrhosis and hepatitis B cirrhosis]. AB - OBJECTIVE: To analyze the differences of coagulation parameters between patients with advanced schistosomiasis cirrhosis and hepatitis B cirrhosis under different degrees of liver function, so as to provide the evidence for further guidance of judging clinical condition and prognosis. METHODS: Sixty-three patients with advanced schistosomiasis cirrhosis and eighty patients with hepatitis B induced cirrhosis hospitalized in Jingzhou Central Hospital from January 2014 to June 2016 were served as an advanced schistosomiasis cirrhosis group and a hepatitis B cirrhosis group, respectively, and ninety-six gastropathy patients excluded from other diseases that might affect coagulation in the same period were served as a control group. The levels of PT, INR, Fib, TT, APTT, and PLT of the patients among the above 3 groups and the cirrhosis patients with different Child-Pugh classes were detected and compared. RESULTS: The differences of the levels of PT, INR, Fib, TT, APTT, and PLT among the 3 groups were statistically significant (F = 84.512, 81.672, 37.612, 104.475, 52.497, 102.233; all P <0.05). The further analysis showed that PT, INR, TT, and APTT of both the advanced schistosomiasis cirrhosis and hepatitis B induced cirrhosis groups were longer than those of the control group, and the PLT levels of both the former 2 groups were lower than that of the control group (all P < 0.05). Compared with the advanced schistosomiasis cirrhosis group, PT, INR, TT, and APTT of the hepatitis B induced cirrhosis group were longer, and the levels of Fib and PLT were lower (all P < 0.05). Among those with the liver function of Grade A, the reduced degree of PLT in the patients with hepatitis B induced cirrhosis was more serious, while for those with the liver function of Grade B and C, the difference between the patients with advanced schistosomiasis cirrhosis and hepatitis B induced cirrhosis was not statistically significant (both P > 0.05). Under all the grades of liver function, TT and APTT of the hepatitis B induced cirrhosis group was longer than those of the advanced schistosomiasis cirrhosis group, and the Fib level of the former was lower than that of the latter. Among those with the liver function of Grade A and B, PT and INR of the hepatitis B induced cirrhosis group were longer than those of the advanced schistosomiasis cirrhosis group; while for those with the liver function of Grade C, the difference between the two groups was not statistically significant (all P > 0.05). CONCLUSIONS: There exist differences of the damage degrees of coagulation function between the patients with advanced schistosomiasis cirrhosis and hepatitis B cirrhosis. When the damage degree of the liver function is lighter, the coagulation function in the patients with hepatitis B cirrhosis decreases more significantly; when the damage degree becomes more severe, APPT in the patients with hepatitis B cirrhosis extends more significantly, while the differences of PLT and PT between them are little.

AB - OBJECTIVE: To evaluate the intervention effect of Yi-Han bilingual health education of schistosomiasis control. METHODS: Baimiao Village in Daqing Town, Xichang City, where Yi Nationality inhabited, was chosen as a pilot to carry out Yi-Han bilingual health education of schistosomiasis control from 2012 to 2015. The villagers and students in the pilot area were investigated by questionnaires before and after the intervention to understand their awareness and correct behavior status on schistosomiasis control. RESULTS: After the intervention of Yi Han bilingual health education of schistosomiasis control for 3 years, the awareness rate and the correct rate of behavior on schistosomiasis control of the villagers in the pilot area improved from 45.79% and 51.12% in 2012 to 97.80% and 98.78% in 2015. As for the students, the two rates mentioned above improved from 64.16% and 60.83% in 2012 to 100% and 98.89% in 2015 respectively, and all the differences between the rates before and after the intervention were statistically significant (all P < 0.01). CONCLUSIONS: The intervention of Yi-Han bilingual health education of schistosomiasis control can obviously improve the knowledge awareness rates and the correct rates of behavior of the residents and students in the gathering area of Yi Nationality. PMID- 29469394 TI - [Pathogen spectrum and epidemic status of major human parasites in Chenzhou City, Hunan Province]. AB - OBJECTIVE: To understand the pathogen spectrum and epidemic status of major human parasites in Chenzhou City, Hunan Province, so as to provide the evidence for parasitic diseases control. METHODS: The survey sites were selected by the stratified cluster sampling method. The intestinal helminthic eggs were detected by Kato-Katz technique. The trophozoites or cysts of intestinal protozoa were detected by saline smear and iodine staining methods. The eggs of Enterubius vermicularis of children from 3 to 6 years old were detected by the cellophane anal swab method. The species of hookworm were identified by the filter paper strip culture method. RESULTS: A total of 7 031 people were detected with the intestinal helminthic infective rate of 1.83% (129 cases). The major parasite was hookworm and there was a statistically significant difference of the infection rates among various parasites (chi2 = 107.77, P < 0.01). All the hookworm larvae were Necator americanus. No intestinal protozoon was detected. There were statistically significant differences of the infection rates among the counties (chi2 = 25.77, P < 0.01). The age of the patients was mainly focused on 30 and above years old and the infection rate was increased with the growth of age (chi2 = 26.21, P < 0.01). Farmers were the main population of the patients and there was a statistically significant difference of the infection rates between farmer and others (chi2 = 29.67, P < 0.01). CONCLUSIONS: The infection rates of parasites are low and hook-worm is the main parasite in the pathogen spectrum in Chenzhou City. However, the infection factors still exist, therefore, effective and scientific measures should be taken to consolidate the achievement. PMID- 29469395 TI - [Analysis of malaria epidemiological characteristics in Hechi City, Guangxi Zhuang Autonomous Region from 2005 to 2015]. AB - OBJECTIVE: To analyze the epidemiological characteristics of malaria in Hechi City, Guangxi Zhuang Autonomous Region from 2005 to 2015, so as to provide the evidence for formulating and adjusting measures of malaria elimination. METHODS: The data of malaria cases in 11 counties of Hechi City from 2005 to 2015 were collected and analyzed by using Micro-soft Office Excel 2003 and SPSS 17.0. RESULTS: A total of 160 malaria cases were reported in Hechi City from 2005 to 2015, and the annual average malaria incidence was 3.6 per million. There were 10 local recurrence cases (accounting for 6.25%, 10/160) and 150 imported cases (accounting for 93.75%, 150/160). For the etiology, Plasmodium vivax accounted for 51.87% (83/160) in these cases, P. falciparum accounted for 34.38% (55/160), P. ovale accounted for 1.25% (2/160), P. malariae accounted for 5.00% (8/160), and the indeterminate accounted for 7.50% (12/160). During the period of 11 years, the malaria incidence first dropped and then rose. There were no local cases after 2009. However, an imported falciparum malaria death case was reported in 2010, a severe imported falciparum malaria case was reported in 2013 and another in 2015. A severe case of maternal-neonatal vivax malaria was reported in 2014. These cases were mainly distributed in 10 counties of Hechi City, with more young male adults who engaged in digging mining. More cases concentrated from April to August. Most of the reported malaria cases were imported, 60.00% (96/160) of them returned from Africa and Southeast Asia, and 33.75% (54/160) from other domestic provinces. The median of the interval from symptom appearance to diagnosis was 5 d, and there was a significant difference among the above years (chi2= 33.40, P<0.05). CONCLUSIONS: Malaria is still an important public health problem in Hechi City, and the appropriate control measures and effective tools should be strengthened for malaria elimination. The key to consolidate the achievements of malaria control is strengthening the malaria monitoring management of the floating population. PMID- 29469396 TI - [Analysis of malaria death cases in Henan Province from 2010 to 2015]. AB - OBJECTIVE: To retrospectively overview the malaria death cases reported in Henan Province and analyze the cause of death. METHODS: The data including basic information, epidemiological survey and medical records of malaria death cases in Henan Province from 2010 to 2015 were collected and analyzed. RESULTS: In the six years, a total of 14 malaria patients were dead. All the death patients were adult males and imported from Africa. They had definite histories of living in malaria-epidemic areas and the symptoms of fever. Twelve patients were diagnosed as malaria after at least twice diagnoses. The average time from symptom appearing to correct diagnosis was 6.5 d. The causes of deaths were misdiagnosis and delayed treatment. CONCLUSIONS: The major reasons of malaria death cases in Henan Province are the failure of correct diagnosis and prompt treatment. Health education of malaria prevention and diagnosis and treatment training of malaria should be strengthened in order to improve the public awareness and the diagnosis ability of clinical doctors for malaria, which can prevent the death of imported malaria cases.

METHODS: Forty-one professional and technical persons from 22 medical and health institutions received the evaluation through the theoretical knowledge exam and laboratory operation skill assessment. RESULTS: The average score of theoretical knowledge exam was (76.5+/-15.6) with the pass rate of 80.5% and excellent rate of 48.9%. The average score, pass rate and excellent rate for Plasmodium blood slide making were (7.3+/-1.5), 87.8% and 41.5% respectively, the average score, pass rate and excellent rate for Plasmodium blood slide reading were (14.0+/-7.2), 31.7% and 12.2% respectively; the average score, pass rate and excellent rate for helminthes microscope examination were (19.4+/-10.4), 24.4% and 0 respectively; the average score, pass rate and excellent rate for Oncomelania hupensis snail identification were (8.6+/ 1.1), 95.1% and 73.2% respectively. The average scores of helminthes microscope examination and Oncomelania hupensis snail identification were higher in the participants with middle-level professional title or above than in the participants with primary level professional title (both P < 0.05). The average scores of theoretical knowledge exam, Plasmodium blood slide reading and helminthes microscope examination were higher in the participants from disease control and prevention institutions than in the staff who came from medical institutions (all P <0.05). CONCLUSIONS: The professional and technical personnel in medical and health institutions in Wuxi do better in theoretical knowledge, Plasmodium blood slide making and Oncomelania hupensis snail identification. However, the capability of parasite microscope examination is urgently needed to be improved in the future.

AB - OBJECTIVE: To understand the status of soil-transmitted nematode infections in Xiding Township, Menghai County, Yunnan Province, so as to provide the reference for formulating the strategy of soil-transmitted nematodosis control. METHODS: Soil-transmitted nematode eggs in feces were detected by the Kato-Katz method, and the eggs of Enterobius vermicularis were detected by the cellophane tape method in children. The soil samples were collected from vegetable, fruit and other crop fields of 15 residents randomly to detect hookworm. RESULTS: The stool samples from 1 002 residents were examined and the soil -transmitted nematode infection rate was 20.06% (201/1 002). The infection rates of hookworm, Ascaris lumbricoides and Trichuris trichura were 18.96% (190 cases), 1.70% (17 cases) and 0.90% (9 cases) respectively. The percentages of people with light infection of hookworm, A. lumbricoides and T. trichura were 97.37% (185/190), 88.24% (15/17) and 100% (9/9) respectively. No infection of E. vermicularis was found. Fifteen soil samples were tested, and no hookworm was found in the soil. CONCLUSIONS: The infection rate of soil-transmitted nematode in Xiding Township, Menghai County is high, but the infectiosity is light. The control and monitoring of soil transmitted nematodosis should be strengthened in this area.

AB - OBJECTIVE: To understand the status of knowledge, attitude and practice (KAP) of foodborne parasitic diseases among senior high school students in Three Gorges Reservoir Region. METHODS: A total of 1 353 senior high school students were selected with the cluster sampling method and investigated with the questionnaires in Zigui County, and the data were analyzed statistically. RESULTS: Among the 1 353 students surveyed, the awareness rates of parasitic diseases, their hazards and transmissions were 62.23% (842 cases), 80.78% (1 093 cases) and 83.89% (1 135 cases) respectively. The awareness rate of parasitic diseases in the students of senior Grade One was higher than that of Grade Two (chi2 = 7.037, P < 0.05). The formation rates of behaviors of refusing of raw food, refusing of unboiled water, and dining at home or school in the students of senior Grade One were higher than those of Grade Two (chi2 = 6.970, 12.749 and 12.921 respectively, and all P < 0.05). Fifty-one percent (690 cases) of students would not have the food with the infection risk of parasitic diseases.

AB - OBJECTIVE: To investigate and analyze the capabilities of Plasmodium microscopic examinations in medical and health organizations in Dongxihu District, Wuhan City, so as to provide evidences for achieving the standard of malaria elimination and malaria control in the future. METHODS: The basic information of the laboratorians and the hardware facilities in 15 microscopic examination stations of Plasmodium were collected and analyzed from 2010 to 2015. Meanwhile, the quality of making, dyeing, cleanliness of all the negatives blood smears were evaluated, and all the positive smears were re-checked in the district during the period above mentioned. RESULTS: Totally, there were 28 laboratorians and 9 qualified microscopes in 15 microscopy stations in Dongxihu District. The age of the laboratorians in the first-level and third-level organizations was mainly from 40 to 50 years old, but the age of those in the second-level organizations was from 20 to 30 years old. The years for microscopic examination working of most of the laboratorians in the first-level and third-level organizations were more than 15 years, while the working years of those in the second-level organizations were mainly less than 10 years. The education level of the laboratorians in the first-level organization was mainly (50.00%) junior college, while the education levels of those in the second and third organizations were mainly bachelor. From 2010 to 2015, 8 561 blood smears were produced and 539 of them were reviewed, the coincidence rates of review were all 100%, and the average qualified rates of making, dyeing, and cleanliness of the negative blood smears were 82.08%, 79.92% and 83.33%, respectively. All the rates mentioned above in 2015 were higher than those in 2010 (chi2 = 26.45, 16.85, 13.93, all P < 0.01). CONCLUSIONS: The capability of microscopic examinations of Plasmodium has improved obviously in Dongxihu District, but the human resources construction and hardware input in this district should be improved, meanwhile, the check on the quality control of microscopic examinations of Plasmodium should be continued, so as to guarantee the sustainable and healthy development of malaria control work in this district.

AB - Advanced schistosomiasis is the most serious clinical type of schistosomiasis. Its diagnosis and treatment are related to many special departments, such as gastroenterology, general surgery, neurology, endocrinology, radiology, traditional Chinese medicine, blood purification, endoscopy, intervention, and ICU. It is necessary to apply a multidisciplinary treatment (MDT) mode. However, the mode has no universal standard and guide in practice. It is very important for the implementation of MDT mode of advanced schistosomiasis to form a treatment expert team, formulate the formal working procedures, and standardize the treatment schedules. The standardized implementation of MDT mode will be important to provide a more effective clinical decision on advanced schistosomiasis.

AB - OBJECTIVE: To master the dynamics of schistosomiasis endemic situation and influencing factors in Mianyang City, so as to provide the evidence for making the control and prevention measures. METHODS: Six villages of six schistosomiasis heavy endemic counties were selected as survey sites according to the national surveillance protocol (Revision in 2014) in Mianyang City. The surveys of the incidences of schistosomiasis in population and livestock as well as the prevalence of Oncomelania hupensis snails were conducted in the 6 national surveillance sites. RESULTS: The serum positive rates of local residents and migrant people were 2.12% and 1.71%, respectively. The infection rate of cattle was 0. The area with snails was 9.344 8 hm2. The mean density of living snails was 0.25/0.1 m2. The occurrence rate of frames with snails was 7.07%, and no infected snails were found. CONCLUSIONS: The infection rates of schistosome in human and livestock are low and the prevalence of O. hupensis snails is stable in the national surveillance sites in Mianyang City. However, the schistosomiasis transmission risk still exists, therefore, we should strengthen the control measures to prevent the rebound of the endemic.

AB - OBJECTIVE: To report the diagnosis and treatment of an imported case of schistosomiasis haematobium, including the pathological features of the disease and therapeutic efficacy of praziquantel. METHODS: The data of the patient with schistosomiasis haematobium were collected, and the pathological features of the bladder tissue were observed under a microscope. More-over, the patient was treated with praziquantel, and his urine was collected before and after the treatment. The eggs in the urine were examined by a microscope after sediment and the miracidia were hatched. RESULTS: The patient once worked in Angola for three months, and after returning home he had the symptoms of intermittent painless terminal hematuresis. It was ineffective after anti-inflammatory treatment in a number of hospitals. There were no sand spots discovered under the cystoscope. However, the inflammatory reaction to parasite with a lot of eosinophils infiltration in the bladder mucosa was found on the pathological sections under a microscope, and the egg structure was observed with individual characteristics. The eggs were detected in the urine and the miracidia were hatched before the praziquantel treatment. The hematuria symptoms disappeared after the praziquantel treatment. The eggs were still detected in the urine 7 days post-treatment, but the miracidium could not be hatched. One month and 6 months post-treatment, the eggs were not detected in the urine. CONCLUSIONS: The imported cases of schistosomiasis haematobium are often misdiagnosed, and therefore, it is necessary to strength the health education to the workers overseas and also to improve the ability of diagnosis in medical staff. For the case reported in this paper, there are typical structure of Schistosoma haematobium eggs and egg granulomas on the pathological sections of bladder tissues. Praziquantel has satisfactory treatment results. PMID- 29469404 TI - [Discussion on ultrasonographic characteristics of schistosomal appendicitis lesions]. AB - OBJECTIVE: To discuss the ultrasonographic characteristics of schistosomal appendicitis lesions. METHODS: Among the patients with schistosomal hepatopathy who were discovered by Color Doppler ultrasound in Huzhou Central Hospital from January 2012 to December 2015, 50 cases with clear history of schistosomiasis and treatment were chosen as a schistosomal hepatopathy group, meanwhile, 50 normal people, who came from non-endemic areas, without schistosomal hepatopathy and schistosomiasis history were chosen as a control group. The two groups were examined by ultrasound scan of the appendix, and the data of the largest diameter of the appendix and the thickness of the appendix wall were collected, and the sonographic characteristics of their appendixes, such as whether the echo of the appendix wall was even or not, were observed. RESULTS: The minimum internal diameter of the appendix cavity and the thickness of the appendix wall of the schistosomal hepatopathy group were (2.090 +/- 0.790) mm and (1.332 +/- 0.313) mm, respectively, the former was significantly narrower than that of the control group, while the latter was significantly thicker than that of the control group (t = 2.647, - 4.526, respectively, both P<0.05). The proportions of those with inhomogeneous echo, indistinctness structure, uneven thickening of the appendix wall, as well as having intestinal contents in the appendix cavity in the schistosomal hepatopathy group were higher than those in the control group (chi2 = 12.000, 18.537, 24.008, 4.244, respectively, all P<0.05). CONCLUSIONS: Schistosomal appendicitis lesions have obvious ultrasonographic characteristics under ultrasound. Ultrasound can play an important role in judging whether the appendix of schistosomiasis patients is involved and discovering the lesion of appendix early.

AB - OBJECTIVE: To investigate the Toxoplasma gondii infection status in pregnant women with history of adverse pregnancy and risk factors in Bazhou area, Hebei Province. METHODS: A total of 302 pregnant women with the history of adverse pregnancy were chosen as respondents (an experimental group) in the hospital from March 2012 to December 2015, and 197 pregnant women without the history of adverse pregnancy as a control group. TOX-IgG and TOX-IgM were detected by using ELISA in two groups. The risk factors of Toxoplasma infection were surveyed by questionnaires. RESULTS: The total positive rate of Toxoplasma antibodies was 28.15% (85/302) in the experimental group, which was significantly higher than that [9.64%(19/197)] in the control group, and the difference was statistically significant (chi2 = 24.76, P<0.05). The positive rates of TOX-IgM, TOX-IgG and TOX-IgM + TOX-IgG were 6.95% (21/302), 18.54% (56/302), and 2.65% (8/302) respectively in the experimental group, which were higher than 2.03% (4/197), 7.61% (15/197), and 0% (0/197) respectively in the control group (chi2 = 6.07, 11.67, 3.76, all P<0.05). The questionnaire survey showed that the proportions of keeping pets, cutting board regardless, liking to eat hot pot or barbecue, eating raw meat, often eating in the restaurant in the pregnant women with Toxoplasma infection were higher than those in the pregnant women without Toxoplasma infection, and the differences were statistically significant (chi2 = 22.57, 3.96, 5.87, 7.40, 4.86, all P<0.05), and therefore, the above unhealthy habits may be important risk factors. CONCLUSIONS: Toxoplasma infection could lead to adverse pregnancy outcomes. Therefore, the above-mentioned unhealthy habits should be avoided, especially during pregnancy period. PMID- 29469406 TI - [Immunomodulatory effects of Treg and Th17 cells in parasitic infections and hygiene hypothesis]. AB - The parasitic infection is still a severe public health problem in developing countries, which threatens people's health and social development. With the advances of molecular biology and immunology, more and more insights have been reached on the immunity and immunopathogenesis to parasitic infections. CD4+ T cells play a central role in the host's immunosurveillance and immunoregulation. Traditionally, naive CD4+ T cells are considered to be able to differentiate into Th1 and Th2 cell subsets both in vivo and in vitro. These Th1 and Th2 cells secret diverse cytokine profiles to exert different functions. Later, two new subsets of CD4+ T cells, Th17 and Treg cells, have been discovered. They are completely different from traditional Th1 and Th2 cells with independent differentiation and regulation mechanism. Ample studies suggest that Treg and Th17 cells play a key role in a variety of parasitic diseases. Furthermore, Treg and Th17 cells have been got increasing attention for their involvement in the hygiene hypothesis. Based on the current advances of researches of Treg and Th17 cells, we make a brief review about immunomodulatory effects of these two subsets in parasitic infections as well as the hygiene hypothesis.

Adult parasites live in the human liver and gallbladder tube system, causing serious complications, such as gallstones, cholecystitis and cholangitis, and even bile duct cancer. The disease is very popular in our country, and the population infection rate is high. It is an important public health problem. Guangdong Province is the earliest province being found of clonorchiasis and with serious epidemic. In the second national human parasitic diseases distribution survey, the results showed that the average infection rate of Clonorchis sinensis in the epidemic areas in Guangdong was 16.42%. It is estimated that the population of C. sinensis infection is over 6 million. The prevention and control of clonorchiasis in China is still in the initial stage currently and we face many challenges such as unclear epidemic characteristics and transmission mode, and lack of long-term prevention and control mechanism. This article introduces the epidemic situation of clonorchiasis and prevention and control strategies and measures in Guangdong.

AB - OBJECTIVE: To analyze the Oncomelania hupensis snail situation in schistosomiasis surveillance sites in Hubei Province from 2009 to 2014. METHODS: From 2009 to 2014, 207 schistosomiasis endemic villages from 13 cities were selected as the surveillance sites in Hubei Province, where the surveillance of snail situation was performed, and the data about the indexes of snail situation during the 6 years were collected and analyzed statistically. RESULTS: From 2009 to 2014, totally 80 963.47 hm2 of snail areas were investigated, and 45 309.77 hm2 of area with snails as well as 364.93 hm2 of area with infected snails were found out, and 1 646 125 snails were captured. In the 207 surveillance sites, the density of living snails was reduced from 0.493 3 snail/0.1 m2 in 2009 to 0.339 3 snail/0.1 m2 in 2014, with a decline rate of 31.22%; the density of infected snails was reduced from 0.000 7 snail/0.1 m2 in 2009 to 0 in 2014; the infection rate of snails was reduced from 0.14% in 2009 to 0 in 2014. The infection rates of snails in the third-rank villages, endemic areas in inner embankment, ditch environment and weed environment were relatively higher. CONCLUSIONS: The snail situation of Hubei Province has been declined steadily. However, the environment of snail breeding has not been changed completely. In order to consolidate the control achievements further, the measures including mollusciciding and snail control projects should be strengthened. PMID- 29469411 TI - [Molluscicidal effect of niclosamide ethanolamine salt powder - granula against Oncomelania hupensis]. AB - OBJECTIVE: To evaluate the molluscicidal effect of niclosamide ethanolamine salt powder-granula (PG) against Oncomelania hupensis. METHODS: The molluscicidal experiment was carried out by the dusting method with niclosamide ethanolamine salt 4% PG. The experiments were respectively done in the laboratory and the tidal flats wetlands. At the same time, the niclosamide ethanolamine salt 4% dustable powder (DP) was as the control group. The single blind method was used for the quality control. The corrected mortality and the median lethal concentration (LC50) were compared between PG and DP in the molluscicidal experiment of the laboratory. The corrected mortality and the reduced rate of snails'density were compared between PG and DP in the tidal flats wetlands. RESULTS: The mortality rates of the snails were 96.67% and 100% respectively on 1 d after dusting 4.0 g/m2 of 4% PG and 2.0 g/m2 of 4% DP in the laboratory. The results showed that the mortality rates of the snails were higher with 4% DP than 4% PG in each dosage (t1 d = 3.60, P < 0.01). The LC50 (s) of 1d, 3 d, 7 d after dusting the molluscicide also showed that the molluscicidal effects of DP were better than PG. The corrected mortality rates were 91.71%, 92.91%, 90.57%, 85.33% and 71.09%, 90.11%, 90.13%, 85.26% on 3 d, 7 d, 15 d, 30 d after dusting with 4% PG and 4% DP, respectively, in the fields. Statistics showed that the mortality rates of snails were higher on 3 d, 7 d after dusting with PG than DP (chi23 d = 731.57, chi27 d = 25.90, P < 0.01), but there were no significant differences between PG and DP on 15d, 30d after dusting (chi215 d = 0.53, chi230 d = 0.01, P > 0.05). CONCLUSIONS: 4% PG has both the adsorption of powder and the penetrability of the granules. The molluscicidal effects of 4% PG and 4% DP are almost the same. However, the drift of the powder was still not effectively controlled. This problem need to be further studied.

AB - OBJECTIVE: To explore the value of automatic photography in the observation of results of Schistosoma japonicum miracidium hatching experiments. METHODS: Some fresh S. japonicum eggs were added into cow feces, and the samples of feces were divided into a low infested experimental group and a high infested group (40 samples each group). In addition, there was a negative control group with 40 samples of cow feces without S. japonicum eggs. The conventional nylon bag S. japonicum miracidium hatching experiments were performed. The process was observed with the method of flashlight and magnifying glass combined with automatic video (automatic photography method), and, at the same time, with the naked eye observation method. The results were compared. RESULTS: In the low infested group, the miracidium positive detection rates were 57.5% and 85.0% by the naked eye observation method and automatic photography method, respectively (chi2 = 11.723, P < 0.05). In the high infested group, the positive detection rates were 97.5% and 100% by the naked eye observation method and automatic photography method, respectively (chi2 = 1.253, P > 0.05). In the two infested groups, the average positive detection rates were 77.5% and 92.5% by the naked eye observation method and automatic photography method, respectively (chi2 = 6.894, P < 0.05). CONCLUSIONS: The automatic photography can effectively improve the positive detection rate in the S. japonicum miracidium hatching experiments.

AB - OBJECTIVE: To evaluate the application status of China Disease Prevention and Control Information System of Hydatid Disease, in which questions existed are summarized in order to promote the system update. METHODS: A questionnaire was designed and distributed to Inner Mongolia, Sichuan, Tibet, Gansu, Qinghai, Ningxia, Xinjiang and Xinjiang Production and Construction Corps to evaluate the application status of China Disease Prevention and Control Information System of Hydatid Disease assistant with telephone. RESULTS: The recovery rate of questionnaires was 87.5%. The statistics of closed questions showed that national application rate of the China Disease Prevention and Control Information System of Hydatid Disease was 100%, of which 15.3% were low frequency users, 57.1% believed the system was necessary, 28.6% considered it was dispensable, and 14.3% believed that it was totally unnecessary. The statistics of open-ended questions indicated that 6 endemic regions suggested to increase the guidance and training, while 4 endemic regions had opinions on sharing the information of the national infectious disease reporting systems and hydatid disease prevention and control information system, and the opinions on turning monthly report to quarterly report, and increasing statistics and analysis module, and 3 endemic regions deemed that the system had logic errors and defects. CONCLUSIONS: The problems of the system are mainly focused on the existence of systemic deficiencies and logic errors, lacking of statistical parameters and corresponding analysis function module, and lacking of the guidance and training, which limits the use of the system. Therefore, these problems should be resolved. PMID- 29469414 TI - [Epidemiological analysis of malaria prevalence in Hubei Province from 2010 to 2014]. AB - OBJECTIVE: To understand the malaria epidemic situation in Hubei Province from 2010 to 2014, so as to provide the evidence for formulating the effective malaria elimination strategies and measures in this province. METHODS: The data from the Disease Reporting Information System of Chinese Center for Disease Control and Prevention were collected and analyzed with the descriptive epidemiological method for the epidemiological characteristics of malaria in Hubei Province from 2010 to 2014. RESULTS: A total of 997 malaria cases were reported in Hubei Province from 2010 to 2014, there were 618 cases of vivax malaria, 352 cases of falciparum malaria, 18 cases of Plasmodium ovale infection, and 9 cases of Plasmodium malariae infection. Among all the reported cases, 479 were local cases and 518 were imported cases. No local malaria cases were reported from Hubei Province since 2013. The overall imported malaria cases showed a gradual increasing trend from 2010 to 2014, the proportion of falciparum malaria increased quite significantly from 2010 to 2014. The malaria cases were mainly distributed in Xiangyang, Wuhan, Xiaogan, Yichang, Jingmen and Suizhou cities, reaching 81.85% of the cases of the whole province. There were 810 male cases and 187 female cases, with a sex ratio of 4.33:1. The local malaria cases were mainly aged from 40 to 69 years, accounted for 78.29% of the total local cases, and 88.22% (457/518) of the whole local cases were concentrated in 20-49 age groups. The local cases were mainly farmers (67.01%). Among the imported malaria cases, the occupation distribution concentrated mainly on the worker, migrant worker, and farmer (63.90%). CONCLUSIONS: The local malaria epidemic situation has been effectively controlled in Hubei Province, which reflects the initiative achievements of malaria elimination. However, there are still many imported malaria cases from abroad. Therefore, the imported malaria from abroad still remains the key of malaria control in Hubei Province. PMID- 29469415 TI - [Epidemiological analysis of imported malaria cases in 20 counties at border region of Yunnan Province from 2012 to 2014]. AB - OBJECTIVE: To analyze the epidemiological characteristics of the imported malaria cases in 20 counties at the border region of Yunnan Province from 2012 to 2014, so as to provide the evidence-based proof for adjusting the strategies in the elimination stage. METHODS: The malaria epidemic data of the 20 border counties in Yunnan Province from 2012 to 2014 were collected and analyzed by using Microsoft Excel 2010. RESULTS: From 2012 to 2014, a total of 1 558 malaria cases were reported in the 20 border counties in Yunnan Province, among which, 1 336 were imported cases, accounting for 85.75% (1 336/1 558), and 222 were indigenous cases, accounting for 14.25% (222/1 558). The number of the imported cases in the above years took up 80.00% (544/680), 89.10% (425/477) and 91.52% (367/401) of the total reported cases in the whole year, respectively. Among all the 1 336 imported cases, 1 045 (78.22%) were infected with Plasmodium vivax, 284 (21.26%) were infected with P. falciparum, 3 were infected with P. malariae, 3 were mixed infection and 1 was an unclassified case; 2 patients died. And 95.58% of the cases were mainly infected in Myanmar (1 277 cases). Young and middle-aged adult of 20-40 years who worked overseas were the predominant (802 cases, 60.03%) and most of the cases occurred from April to June of the year (679 cases, 50.82%). Those cases mainly distributed in Tengchong (459 cases), Ruili (366 cases), Yingjiang (191 cases) and Mangshi (78 cases). CONCLUSIONS: The epidemic situation of imported malaria is serious in the border region of Yunnan Province. Therefore, the surveillance system of malaria control needs to be well planned and managed to ensure timely case detection and prompt response at the elimination and post-elimination stage. PMID- 29469416 TI - [Diffusion, population dynamics and potential distribution of Armigeres subalbatus]. AB - OBJECTIVE: To investigate the diffusion trend of Armigeres subalbatus and analyze its potential geographic distribution in China. METHODS: The trend analysis of diffusion and population dynamics were carried out based on three aspects including literature reports, information of museum specimens and new collection records from our field survey. To compare the potential geographic distribution, two ecological niche models were constructed by Maxent software based on the geographic presence occurrence data and 20 environmental variables. The final models were evaluated with the receiver operating characteristics curve (ROC). The analyses of variable contributions were confirmed by using the Jackknife method. RESULTS: The populations in Weifang and Weihai, Shandong Province were reported for the first time. The results showed that this species was spread to the Palaearctic Northern Region and reached 42 degrees north latitude regions. In some areas, it gradually developed into a dominant species. A total of 294 georeferenced occurrence points of A. subalbatus were found out. Two predictions of Maxent models were established based on the presence occurrence data in 2000 and 2016, respectively. The results showed that the current distribution range of A. subalbatus had been significantly northward expanded compared with 2000. It means that the potential suitable area gradually spread northward. The ROC analysis results showed the AUC values were 0.980 and 0.982, and it indicated that the models had a high reliability. The Jackknife method displayed that the precipitation of warmest quarter, precipitation of wettest month and precipitation of wettest quarter were the dominant environmental variables that mainly contributed to the distribution of A. subalbatus. CONCLUSIONS: A. subalbatus distribution gradually spreads northward, and climate warming is probably the main reason for the diffusion. It could affect the local mosquito species composition and increase the risk of mosquito-borne disease transmission. PMID- 29469417 TI - [Effect evaluation of three ELISA kits in detection of paragonimiasis]. AB - OBJECTIVE: To evaluate the effects of 3 kinds of ELISA reagents on the detection of human paragonimiasis. METHODS: A total of 45 serum samples from patients with paragonimiasis, 218 serum samples from patients with other parasitic diseases as well as 80 serum samples from healthy people were detected by GD-ELISA (IgG antigen ELISA detection reagent), ESELISA (using excretory/secretory (ES) products of Paragonimus westermani), and sAg-ELISA (using semi-purified antigen (sAg) of P. westermani), respectively. The effects of the 3 reagents were evaluated and compared. RESULTS: The sensitivities of GD-ELISA, ES-ELISA, and sAg ELISA were 95.6% (95% CI:89.6%~100.0%), 93.3% (95% CI:86.0%~100.0%) and 86.7% (95% CI:76.8%~96.6%), respectively; the specificities of the above three reagents were 88.6% (95% CI:85.0%~ 92.2%), 88.9% (95% CI:85.3%~92.5%) and 99.0 % (95% CI:97.9%~100.0%), respectively, and the Youden indexes of them were 0.84, 0.82 and 0.86, respectively. CONCLUSIONS: sAg-ELISA is more suitable than GD-ELISA and ES-ELISA for clinical sample tests in paragonimiasis endemic areas in China.

AB - OBJECTIVE: To explore the effect and mechanism of CD4+CD25+ Tregs (Tregs) on the protective efficacy of gluthatione-S-transferase (GST) against Schistosoma japonicum in mice. METHODS: Female BALB/c mice were divided randomly into five groups:a normal control group, an infected control group, an anti-CD25mAb group, a GST immunization group and a combination group with GST immunization and anti CD25 mAb. The GST group and combination group were injected percutaneously with GST 50 MUg each mouse, the other two groups were injected with equal volume PBS. The immunization was performed for 3 times for two-week interval, and 2 weeks after the last immunization, each mouse was challenged with 40 S. japonicum cercaria. Two weeks post-infection, the combination group and anti-CD25 mAb group were injected intraperitoneally with 300 MUg antiCD25 mAb each mouse. The mice were succumbed 2 weeks, 3 weeks, 4 weeks and 5 weeks post-infection respectively. The percentages of CD4+CD25+ Tregs in splenocytes of mice were measured with flow cytometer. The levels of IFN-gamma, IL-2, IL-4, IL-5 and TGF-beta in cell cultural supernatants were determined by sandwich-ELISA after stimulation with Con A. The liver sections were stained with hematoxylin and eosin. RESULTS: The worm burden in the combination group (15.80+/-2.74) was significantly lower than those of the infected control group (27.78+/-3.15), anti-CD25 mAb group (21.50+/ 4.21), and GST group (20.84+/- 6.46). Compared to those of the infected control group, the percentages of CD4+CD25+ Tregs were significantly higher in the GST group, while the percentages of CD4+CD25+ Tregs were significantly lower post anti-CD25 mAb-administration. Regardless of GST administration, the levels of IFN gamma, IL-2, IL-4 and IL-5 after anti-CD25 mAb were significantly higher than those of the infected control groups. There were no significant differences of egg granuloma and the level of TGF-beta between each group. CONCLUSIONS: CD4+CD25+ Tregs could be partially blocked by anti-CD25 mAb while Th1 and Th2 type immunization response could be enhanced, which plays a role in improving the protective efficacy of GST against of S. japonicum.

AB - OBJECTIVE: To explore the correlation between the genetic dissimilarity and heterozygosity of mates and the pathogenicity of Schistosoma japonicum in the definitive host. METHODS: By using seven microsatellite loci markers, S. japonicum genotyping of sixteen pairs randomly mated was performed, the genetic dissimilarity and heterozygosity were calculated between the mates, and the correlation between the genetic dissimilarity and heterozygosity of the mates and the pathogenicity of S. japonicum in the definitive host was evaluated. RESULTS: There was a significant correlation between the genetic similarity of S. japonicum mates and the mean number of eggs per worm pair in the liver and intestinal tissue (r = 0.501 6, P < 0.05; r = 0.796 5, P < 0.01, respectively) and the hatching rate of deposited eggs in the liver (r = 0.508 3, P < 0.05), respectively. There was no correlation between the genetic similarity of the mates and hepatosplenomegaly per worm pair (r = 0.109 5, P > 0.05; r = 0.265 3, P > 0.05, respectively) and the average diameter of granuloma in the liver (r = 0.272 7, P > 0.05), respectively. There was no correlation between the heterozygosity of the mates and all the pathological parameters of S. japonicum in the definitive host (P > 0.05). CONCLUSIONS: There is the correlation between the genetic dissimilarity of the mates and the pathogenicity of S. japonicum in the definitive host, and the genetic dissimilarity is greater, pathogenicity is weaker. There is no correlation between heterozygosity of the mates and the pathogenicity of S. japonicum in the definitive host.

AB - OBJECTIVE: To observe the effect of excretory/secretory products from Trichinella spiralis adult worms (AES) on cecal ligation and puncture (CLP) -induced sepsis in mice. METHODS: Forty-eight BALB/c mice were randomly divided into 3 groups:a sham operation group (PBS + sham group, Group A), a CLP-induced sepsis group (PBS+CLP group, Group B) and an AES treatment group (AES+CLP group, Group C). The mice of each group were intraperitoneally injected with 25 MUg of AES or PBS only as a control in a total volume of 200 MUl. Eight mice from each group were selected randomly for survival analysis of 96 hours. The other 8 mice in each group were observed for pathological changes in the lung, liver and kidney tissues by HE staining 12 h after CLP, and then determined for the detection of cytokines including TNF-alpha, IL-1beta, IL-6, IL-10 and TGF-beta in the sera by ELISA. RESULTS: The difference among the survival rates of mice in the 3 groups was statistically significant (chi2 = 21.16, P < 0.05). Compared to Group A (100%), the survival rate of mice in Group B (0) decreased significantly (P < 0.05), and also the pathological damage degrees in the lung, liver and kidney tissues of the mice in Group B increased significantly after CLP. Compared with the mice in group B, the survival rate of those in Group C (70%) increased significantly (P < 0.05), and the pathological damage degrees in the lung, liver and kidney tissues of the mice in Group C decreased significantly after the treatment with AES. The differences among the levels of pro-inflammatory cytokines TNF-alpha (F = 27.11, P < 0.05), IL1beta (F = 18.75, P < 0.05) and IL-6 (F = 100.93, P < 0.05) in the sera of the mice in the three groups were statistically significant. Compared with the mice in Group A, the levels of the 3 cytokines of those in Group B increased significantly (all P < 0.05). However, after the treatment with AES, the levels of the pro-inflammatory cytokines of those in Group C decreased significantly (all P < 0.05). The differences among the levels of immunoregulatory cytokines IL-10 (F = 10.88, P < 0.05) and TGF-beta (F = 11.37, P < 0.05) in the sera of the mice in the three groups were also statistically significant. Compared with the mice in Group B, the levels of IL-10 and TGF-beta of those in Group C were higher after treatment with AES (both P < 0.05). CONCLUSIONS: T. spiralis AES has a therapeutic potential for alleviating sepsis induced by CLP in mice.

AB - OBJECTIVE: To observe the Oncomelania hupensis snail control effects of molluscicides with different formulations in the ditch with unstable water level in field of marshland and lake areas, so as to provide the evidence for formulating the prevention strategies. METHODS: A drainage channel with O. hupensis snails in Jiangling County, Jingzhou City were selected as the study field, then it was divided into 6 segments, except 1 segment was treated as the blank control group for observing the natural mortality rate of the snails, the other 5 segments were treated as observation groups, where 4% niclosamide ethanolamine salt powder, 5% niclosamide ethanolamine salt granule, 25% suspension concentrate of niclosamide ethanolamine salt, 26% suspension concentrate of metaldehyde and niclosamide ethanolamine salt, 50% niclosamide ethanolamine salt wettable powder were applied respectively. Before and after the mollusciciding, the snail surveys were carried out through the systematic sampling method, and the short- and long-term effects of snail control were observed, and the mortality rates of the snails on the slope above the water level and those below the water level were compared. RESULTS: When 7 d and 15 d after mullusciciding, the mortality rates of snails on the slope above the water level in each observation group were 79.52%-97.87% and 90.43%-96.30%, respectively, when compared with those before mollusciciding, all the differences were statistically significant (all P < 0.01). When 7 d after mullusciciding, the mortality rates of snails below the water level in each observation group were 17.11%-50.00%, which were all lower than those of the snails on the slope above the water level in the corresponding groups (all P < 0.05); when 15 d after mullusciciding, the rates were 9.43%-95.24%, and those in 25% suspension concentrate of niclosamide ethanolamine salt, 26% suspension concentrate of metaldehyde and niclosamide ethanolamine salt, 50% niclosamide ethanolamine salt wettable powder groups were all lower than those of the snails on the slope above the water level in the corresponding groups (all P < 0.01). Compared with the densities of living snails before mollusciciding, those 6 months after mollusciciding in each observation group decreased by 70.21%-78.98%. CONCLUSIONS: The molluscicides in the formulation of powders and granule are suitable for both the snail environment with or without water, while those in the formulation of suspension agents and wettable powders are suitable only for environments with water.

China, 5 provinces (municipality and autonomous region), i.e., Shanghai, Zhejiang, Fujian, Guangdong and Guangxi, had achieved elimination, and 7 provinces of Sichuan, Yunnan, Jiangsu, Hubei, Anhui, Jiangxi and Hunan had achieved transmission control by the end of 2016. There are 451 endemic counties (cities, districts) covering 257 million people, specifically including 29 692 endemic villages of 69.39 million people at risk. Among the 451 endemic counties (cities, districts), 35.25 % (159/451), 42.35% (191/451) and 22.39% (101/451) reached the criteria of elimination, transmission interruption and transmission control, respectively in 2016. By the end of 2016, it was estimated of 54 454 infections of schistosome, decreased by 29.46% compared with 77 194 in 2015. No acute schistosomiasis case was reported in 2016. There were 30 573 advanced schistosomiasis cases documented in 2016. A total of 8 500 710 individuals received schistosomiasis examinations and 600 individuals were parasitologically diagnosed, decreased by 83.36% compared with 3 606 in 2015. The Oncomelania hupensis snail survey was performed in 22 140 endemic villages and O. hupensis snails were found in 7 106 villages, accounting for 32.109% of the total villages, with 20 newly detected villages with snails. The snail survey covered area of 813 963.91 hm2 and snails were found in an area of 235 096.04 hm2, including a newly detected area of 1 346.48 hm2. No schistosome-infected snails were found in 2016. A total of 881 050 bovines were raised in the schistosomiasis endemic area. Of them, 510 468 bovines received examinations, resulting in 8 schistosome-infected bovines. There were 147 642 schistosomiasis cases receiving drug treatment in 2016, with 2 303 555 individuals undergoing expanded chemotherapy; there were 9 bovines with schistosomiasis receiving drug treatment, with 439 857 bovines undergoing expanded chemotherapy; a total of 139 483.84 hm2 area with snail control by using molluscicides, with actual molluscicide-treated area of 73 941.75 hm2; and 3 101.52 hm2 snail habitants were treated by environmental modification. Based on the data from the 454 national schistosomiasis surveillance sites, the mean Schistosoma japonicum infection rate was 0.02% and 0.0078% in humans and bovines, respectively. No schistosome-infected snails were found in all the surveillance sites. The results demonstrate a decline in the endemicity of schistosomiasis in P. R. China compared with the level of 2015. However, the distribution area of snails in China is still large and the infection source of schistosomiasis still exists to some extent in some endemic areas; in some regions, the task to reach the standard of transmission interruption is still arduous. There are still objective factors of epidemic and transmission and risk factors of endemic reversal and rebound for schistosomiasis. So, further control and effective surveillance as well as accurate prevention and control should be implemented to promote the elimination process on schistosomiasis in P. R. China.

AB - OBJECTIVE: To investigate the difference of biological characteristics between the praziquantel-resistant and -susceptible isolates of Schistosoma japonicum in intermediate host Oncomelania hupensis snails. METHODS: Mice were infected with cercariae of praziquantel-resistant and -susceptible isolates of S. japonicum, and the parasite eggs were collected 37 days post-infection to hatch miracidium. Then, the snails were infected with the miracidium of each parasite isolate. The snail infection, survival rate of infected snails, prepatent period of cercariae, and the total number of cercariae shed from each infected snail were observed and compared between the praziquantel-resistant and -susceptible isolates of S. japonicum. RESULTS: If each snail was exposed to a single miracidium, there were significant differences between the praziquantel-resistant and -susceptible Jiangsu isolates in the snail infection (8.99% vs. 19.74%; chi2 = 3.948, P = 0.047) and the number of cercaria released from a single snail (1 460.2 vs. 1 039.3; t = 2.507, P = 0.02), and there were significant differences between the praziquantel-susceptible and -resistant Hunan isolates in the snail infection (10.00% vs. 21.52%; chi2 = 3.980, P = 0.046) and the number of cercaria released from a single snail (1 319.4 vs. 1 003.5; t = 2.566, P = 0.017). However, there were no significant differences between the praziquantel-resistant and susceptible isolates of S. japonicum in the prepatent period of cercariae and the survival rate of infected snails (P > 0.05). CONCLUSIONS: The praziquantel resistant isolate of S. japonicum has a higher susceptibility to O. hupensis but less cercaria released from each infected snail than the susceptible isolate.

AB - OBJECTIVE: To investigate the biological characteristics of the praziquantel resistant isolate of Schistosoma japonicum in mice, so as to explore the pathogenicity to definitive hosts and transmission intensity of the praziquantel resistant isolate of S. japonicum. METHODS: Mice were infected with the cercariae released from two praziquantel-resistant isolates and two praziquantel susceptible isolates of S. japonicum. The mouse-Oncomelania hupensis snail-mouse cycle was established and maintained in the laboratory. The prepatent period of parasite eggs, egg production, egg distribution in mice, parasite susceptibility to mice and egg size were investigated in each parasite isolate. RESULTS: The prepatent period of parasite eggs, egg counts in mouse feces, adult worms recovered from each mouse, egg counts in mouse tissues, egg counts in the mouse liver, and egg counts in intestine tissues were 36.1 d and 36.8 d (t = 0.907, P = 0.372), 14.6 / 100 mg and 21.2 / 100 mg (t = 2.946, P = 0.007), 20.5 and 25.1 worms per mouse (t = 2.128, P = 0.042), 31 303 and 38 594 per paired adult worm (t = 2.185, P = 0.04), 14 810 and 19 715 per paired adult worm (t = 2.934, P = 0.007), and 16 493 and 18 879 per paired adult worm (t = 1.044, P = 0.309) in the mice infected with Jiangsu praziquantel-susceptible and -resistant isolates of S. japonicum, respectively, and there were no significant differences between Jiangsu praziquantel-susceptible and -resistant isolates of S. japonicum in the length of paired adult worms (t = 0.328, P = 0.744), female adult worms (t = 0.386, P = 0.701) or male adult worms (t = 0.332, P = 0.741). The prepatent period of parasite eggs, egg counts in mouse feces, adult worms recovered from each mouse, egg counts in mouse tissues, egg counts in the mouse liver, and egg counts in intestine tissues were 35.5 d and 35.6 d (t = 0.169, P = 0.867), 13.3/100 mg and 18.9/100 mg (t = 3.622, P = 0.001), 17.6 and 25.1 worms per mouse (t = 3.153, P = 0.004), 30 932 and 53 903 per paired adult worm (t = 3.865, P = 0.001), 12 307 and 26 363 per paired adult worm (t = 4.388, P < 0.01), and 18 625 and 27 541 per paired adult worm (t = 2.679, P = 0.012) in the mice infected with Hunan praziquantel-susceptible and -resistant isolates of S. japonicum, respectively, and there were no significant differences between Hunan praziquantel - susceptible and - resistant isolates of S. japonicum in the length of paired adult worms (t = 0.853, P = 0.397), female adult worms (t = 0.573, P = 0.569) or male adult worms (t = 0.742, P = 0.461). CONCLUSIONS: The praziquantel resistant isolate of S. japonicum has a higher parasite egg production and more eggs deposited in the mouse liver than drug-susceptible isolate, suggesting that the praziquantel-resistant isolate of S. japonicum exhibits a greater pathogenicity to definitive hosts. In addition, more parasite eggs are detected in the feces of mice infected with the praziquantel-resistant isolate of S. japonicum relative to the drug-susceptible isolate, indicating that the praziquantel-resistant isolate of S. japonicum exhibits a greater transmissibility than the drug-susceptible isolate.

AB - OBJECTIVE: To evaluate the role of new strategy in the transmission control of schistosomiasis in Poyang Lake region. METHODS: The information and epidemic data of schistosomiasis control were collected and analyzed in Poyang Lake region from 2005 to 2016. RESULTS: After eleven years of carrying out the new strategy, thirteen counties achieved the objective of transmission control in Poyang Lake region. In 2016, the number of schistosomiasis cases and human infection rate were 10 301 and 0.03%, decreased by 89.64% and 99.45% compared with those in 2005, respectively. The number of cattle and schistosome -infected cattle were 68 152 and 5, decreased by 50.84% and 99.83% compared with those in 2005, respectively. The average density of Oncomelania hupensis snails was decreased by 61.52%. No schistosome-infected snails were found since 2014. CONCLUSIONS: The new strategy accurately locates the key points and targets of schistosomiasis transmission chain, which has controlled the human and animal's fecal eggs from polluting grassland, and cut off the transmission chain, reduced both the infection rates of human and animal and the re-infection risk, and promoted to achieve the target of schistosomiasis transmission control in Poyang Lake region.

AB - OBJECTIVE: To evaluate the effect of the water conservancy schistosomiasis control projects combined with molluscicide to control Oncomelania hupensis snails in the rivers connecting with the Yangtze River. METHODS: The water conservancy schistosomiasis control projects of Zhujiashan River, Qili River and Gaowang River were chosen as the study objects in Pukou District, Nanjing City. The data review method and field investigation were used to evaluate the effect of the water conservancy schistosomiasis control projects combined with molluscicide to control O. hupensis snails. RESULTS: After the projects of the water level control and concrete slope protection and mollusciciding were implemented, the snails in the project river sections were completely eliminated. The snail diffusion did not happen in the inland irrigation area too. In the outside of the river beach, though the snails still existed, the snail densities plunged below 1.0 snail per 1.0 m2. CONCLUSIONS: The comprehensive measures of the combination of water level control, concrete slope protection and mollusciciding can effectively control and eliminate the snails, and prevent the snails from spreading.

AB - OBJECTIVE: To understand the risk situation of imported schistosomiasis and its main influencing factors in Shanghai City from 2005 to 2015. METHODS: A retrospective survey was performed, and the database was established based on the data collection of imported schistosomiasis, Oncomelania hupensis snail situation and mobile population in Shanghai City from 2005 to 2015. RESULTS: From 2005 to 2015, the mobile population in Shanghai City increased by 123.92%, which reached about 9 816 500, and 54.70% of them were located in the inner suburban districts. The accumulated areas with snails of 7.13 hm2 were found in 16 towns of 4 outer suburbs (excluding Chongming District). A total of 23 cases of imported schistosomiasis were found in Shanghai City, and the number of the imported schistosomiasis cases was on the downward trend (rs = -0.782, P = 0.004). From 2005 to 2009, 11 out of 13 imported schistosomiasis cases (84.62%) were distributed in the inner suburban districts where no O. hupensis snails were found at the same time. From 2010 to 2015, 9 out of 10 imported schistosomiasis cases (90%) were distributed in the outer suburban districts where O. hupensis snails were found at the same time. CONCLUSIONS: The number of imported schistosomiasis cases in Shanghai is on the downward trend. However, the threat of imported schistosomiasis to the prevention and control of schistosomiasis in Shanghai City should not be ignored.

AB - OBJECTIVE: To analyze the epidemiological characteristics of imported malaria cases and investigate the influencing factors of severe cases in Anhui Province, so as to provide the evidence for improving the control strategy. METHODS: The epidemiological data of imported malaria cases in Anhui Province from January 1st, 2012 to April 18th, 2017 were collected and analyzed. RESULTS: The imported malaria cases in Anhui Province were mainly young men of migrant workers. There were imported malaria cases in 79% (83/105) of counties (districts) in Anhui Province.. Totally 686 imported malaria cases were recorded, in which there were 62 severe cases (9.04%), and four death cases with the mortality rate of 0.58%. The age, education, initial diagnosed departments, initial diagnosed results, time from onset to seeing a doctor, and time from seeing a doctor to diagnosis were the influencing factors for the severe cases. CONCLUSIONS: The proportion of severe imported malaria cases is high in Anhui Province. The monitoring sensitivity, clinician's awareness of malaria diagnosis, and health education for migrant workers should be improved.

AB - OBJECTIVE: To analyze the status and trends of soil-transmitted nematode infections in Jiangxi Province from 1989 to 2014, so as to provide the evidence for generating the strategy of soil-transmitted nematode prevention and control. METHODS: The data of three epidemiological surveys on human parasitic diseases (in 1989, 2002 and 2014) were classified and analyzed. The stool examination by Kato-Katz's thick smear method was adopted for the investigation of soil transmitted nematode infections. RESULTS: The total infection rate of soil transmitted nematodes decreased by 91.89% from 77.67% in 1989 to 6.30% in 2014, in which the infection rate of Ascaris lumbricoides decreased by 98.78% from 71.11% to 0.87%, the infection rate of Trichuris trichiura decreased by 96.80% from 29.67% to 0.95%, and the infection rate of hookworm declined by 73.57% from 17.63% to 4.66%. The infection rates of soil-transmitted nematodes in the female were higher than those in the male in three surveys. In different ecological districts, the infection rates of soil-transmitted nematodes in the female were also higher than those in the male, except in Zhe-Min Ecological District in 2002 and 2014. A declined trend of the infection was showed in all age-groups in the three surveys, but it slowed down by the growth of age, i.e., the reduction rate was 97.03% in the age group of < 10 years while 80.62% in the age group of >70 years. In 2014, the number of persons infected with soil-transmitted nematodes occupied 65.4% of the whole number of persons infected with intestinal parasites. CONCLUSIONS: The mean infection rates of soil-transmitted nematodes decrease obviously in human population in different ecological districts, but the soil transmitted nematodes are still the main species in intestinal parasite infections. The sequence of dominant species changes from A. lumbricoides, hookworm and T. trichiura in 1989 to hookworm, T. trichiura and A. lumbricoides in 2014. The rural female and elder people are the key population, while hookworm is the key species for the prevention and control of soil-transmitted nematodes.

AB - OBJECTIVE: To understand the current status of the sanitation of freshwater aquaculture environments, and Clonorchis sinensis infection of freshwater fish in the aquaculture and market in a city of Pearl River Delta region, so as to provide the evidence for formulating the prevention and control strategy of clonorchiasis sinensis. METHODS: In 2016, based on the distribution of freshwater aquaculture, 36 freshwater fish ponds among 14 towns were selected for sampling and investigation, and 10-20 pieces were collected from each pond. Besides, 3 aquatic product wholesale markets were included, among which 3-6 stalls were selected from each market, and 20-30 pieces were collected from each stall. The metacercaria in the fish was examined by the digestion method. RESULTS: In the 36 fish ponds, there were no toilets with the stool being drained into fish ponds directly, and there was only one pond with duck sheds with the stool being drained into fish ponds directly. Totally 437 pieces of freshwater fish from ponds were detected, with a metacercaria positive rate of 4.35% (19/437). The metacercaria positive fish were distributed in 50% (7/14) of towns and 25% (9/36) ponds. The positive rates of crucian carp, grass carp, dace, aristichthysnobilis, and tilapia were 13.95% (6/43), 4.76% (9/189), 4.44 (2/45), 1.55% (2/129), and 0 (0/31) respectively, with statistically significant difference (chi2 = 13.46, P = 0.01). Totally 307 pieces of freshwater fish were collected from the wholesale markets, with a total positive rate of 1.95% (6/307). The positive rate of grass carp and aristichthysnobilis were 3.20% (4/125) and 2.78% (2/72) respectively, and no positive samples were found in crucian carp, dace and tilapia, with no statistically significant difference among the different fish in the infection rate (Fisher exact P = 0.75). CONCLUSIONS: The sanitation of freshwater aquaculture environments in a city of Pearl River Delta region is relative good. However, there are different degrees of Clonorchis sinensis infection of freshwater fish in some aquaculture environments and markets.

AB - OBJECTIVE: To investigate the effect of the type of neighborhoods on the population structure and dynamics of mosquitoes. METHODS: The adult population dynamics and larvae breeding of mosquitoes in four different types of neighborhoods were investigated in Yangzhou City. RESULTS: The number of trapped mosquitoes was the largest in the urban villages, and more than 800 adult mosquitoes were trapped in each urban village, which was significantly higher than that of ordinary and high quality residences. Aedes albopictus and Culex pipiens pallens were dominant species (D > 10%) in the four types of residential areas, and Ae. albopictus was the most dominant species (D > 57%). The peak occurrence of Ae. albopictus in different areas occurred in early June, and it occurred again in the urban village in the middle of September. The occurrence quantity of Cx. pipiens pallens was stable in the ordinary residence and high quality residence, while in the urban village and resettlement residential area, the peak occurred in mid-October. The orders of positive rates, densities and the numbers of mosquitoes in the different types of residential areas were:the urban villages> the resettlement residence> the ordinary residence> the high quality residence. The water vat had the highest positive rate in all kinds of larval habitats, followed by tires and green belt with garbage water. CONCLUSIONS: The main mosquito species in the four different types of residential areas are all Ae. albopictus and Cx. pipiens pallens, but the positive rate, density and the number of mosquitoes in the different types significantly change, especially in the urban villages, the number and the occurrence peak are significant different from those in the other types of residential areas. PMID- 29469451 TI - [Epidemiological characteristics of malaria prevalence in Danyang City from 2004 to 2015]. AB - OBJECTIVE: To analyze the epidemiological characteristics of malaria prevalence in Danyang City from 2004 to 2015, so as to provide the evidence for formulating the strategy of prevention and control of malaria. METHODS: The data of malaria serum tests, the reported malaria cases from the Internet Reporting System, and the epidemiological case survey from 2004 to 2015 as well as the mosquito monitoring data from 2008 to 2015 were collected and analyzed. RESULTS: From 2004 to 2015, 58 malaria cases were reported in Danyang City, with an average annual incidence rate of 0.6/105. Among the cases reported, vivax malaria accounted for 65.52% (38/58), falciparum malaria accounted for 5.17% (3/58), oval malaria accounted for 1.72% (1/58), and unclassified subtype accounted for 27.59% (16/58). The local infection cases accounted for 31.03% (18/ 58), and the imported cases accounted for 68.97% (40/58). There were no local infections since 2011. Anopheles sinensis, the only malaria vector in Danyang City, was still prevalent, but its density was low. CONCLUSIONS: Imported malaria poses a serious threat to the malaria elimination achievements in Danyang City, and the surveillance and disposal of imported malaria need to be strengthened.

AB - OBJECTIVE: To explore the biological functions of E77.43, a gene segment of Microtus fortis, in treating Schistosoma japonicum infection. METHODS: Recombinant retroviral vectors of pRevTRE-E77.43 was constructed, and recombinant retroviral vectors were transfected into PA317 cells, and the stable cell lines were obtained by hygromycin screening, followed by the packaging, concentration and purification of recombinant retrovirus. The virus was transferred to the mice infected by S. japonicum via intravenous or intraperitoneal injection, through which the express of target gene and the treatment function in vivo were observed. RESULTS: The experiment showed the recombinant virus injected mice could efficiently express E77.43 on the 7th day after the injection which lasted for forty-five days thereafter. A significant reduction in adult worms (31.0%) and a high reduction (35.0%) in liver eggs were induced by pRevTRE-E77.43, while the reduction in adult worms and that in liver eggs was 1.2% and 0.9% induced by pRevTRE respectively (t = 3.524, 9.485, both P<0.01). CONCLUSIONS: pRevTRE-E77.43 could be used for the treatment of S. japonicum infection, indicating that E77.43 may involve in the natural resistance of M. fortis to S. japonicum infection.

AB - OBJECTIVE: To master the prevalence status of schistosomiasis in Yunnan Province in 2016, so as to provide the evidence for formulating the control strategy and intervention measures. METHODS: The schistosomiasis heavy-endemic villages were selected from each of 18 endemic counties as the survey sites. Then, the serological and etiological tests were carried out in the local residents and floating population, and the infection status of the livestock, field feces and Oncomelania hupensis snails were surveyed. RESULTS: The serum positive rate of schistosomiasis of local residents was 8.78% and the serum positive rate was 2.26% of floating population. No schistosome eggs were found in the stool examinations in the population. The area with snails was 80.054 6 hm2 in 2016 with an increasing rate of 45.47% compared to that in 2015. The average density of living snails was 0.031 7/0.1 m2. No schistosome-infected snails were found for the last four years and no new area with snails was found for the last three years. No positive livestock or feces were found. CONCLUSIONS: The schistosomiasis epidemic situation is stabilized in Yunnan Province in 2016. However, the area with snails and the number of living snails are increasing, and therefore, the schistosomiasis epidemic risk still exists. So, the comprehensive control measures should be strengthened continuously. PMID- 29469454 TI - [Clinical features of 14 cases of cerebral schistosomiasis in Jiangxi Province]. AB - OBJECTIVE: To discuss the clinical features of cerebral schistosomiasis. METHODS: The clinical data of fourteen patients with cerebral schistosomiasis from March 2010 to March 2016 were collected and analyzed retrospectively. RESULTS: The schistosomiasis immunological tests of sera and cerebrospinal fluids from the fourteen patients were all positive. Eosinophils increased in ten cases, and the proportion was 5.1%-60.3%. Schistosoma eggs were found in seven cases by the fecal Kato-Katz method. Fourteen cases were all infected with Schistosome japonicum. Twelve cases were diagnosed as chronic type, and two cases as acute type. Thirteen patients received medical treatment, of which twelve were cured, and one improved. One patient received the surgical resection of the lesion. CONCLUSIONS: The clinical manifestations of cerebral schistosomiasis mainly include seizure, headache, dizziness and fever. In the enhanced head magnetic resonance imaging (MRI), the lesions are clustered and merged into lumps, which is the characteristic image of cerebral schistosomiasis japonica. The praziquantel treatment can achieve a good prognosis. PMID- 29469456 TI - [Epidemiological analysis of imported malaria in Yancheng City from 2011 to 2015]. AB - OBJECTIVE: To understand the epidemiological trend of imported malaria and its monitoring and control effect in Yancheng City from 2011 to 2015, so as to provide the evidence for adjusting the prevention and control strategy. METHODS: The data of malaria surveillance, epidemic, prevention and control were collected and analyzed in the districts and counties of Yancheng City from 2011 to 2015. RESULTS: From 2011 to 2015, there were 104 imported malaria cases reported, and the most cases (52 cases, 50%) were reported from Jianhu County. Most of the cases were males (only 2 females), the average age was 38.8 years, and the occupation was mainly labor service worker abroad (94 cases, 97%). The infection source of these cases mainly came from Africa. From 2011 to 2015, 151 980 fever patients received malaria blood tests, and the positive rate was 0.07%. Falciparum malaria cases were the most (90 cases, 86.5%). The confirmed diagnostic rate of malaria within 24 hours increased year by year. All the 104 patients received the standardized treatment. CONCLUSIONS: There are no local malaria cases in Yancheng City from 2011 to 2015, and in the next stage, the monitoring and prevention should be focused on imported malaria, including shortening the confirmed diagnostic time and improving the diagnostic efficiency. PMID- 29469455 TI - [Case analysis and control strategy of imported malaria in Qingcheng District, Qingyuan City from 2011 to 2016]. AB - OBJECTIVE: To understand the characteristics of imported malaria cases in Qingcheng District, Qingyuan City and explore the strategies and priorities in prevention and control, so as to provide the evidence for improving the diagnosis, treatment and management of imported malaria. METHODS: The data of imported malaria as well as the case epidemiological investigations were collected and retrospectively analyzed for the species composition, original countries, population distribution, regional distribution, onset situation, diagnosis, treatment, etc. in Qingcheng District from 2011 to 2016. RESULTS: The number of imported malaria cases was 13 from 2011 to 2016. All the patients were confirmed by laboratory, and of which, 9 patients infected with Plasmodium falciparum, 1 with P. vivax, 1 with P. ovale and 2 with mixed infections (P. vivax and P. falciparum). The yearly incidence of imported malaria presented an uptrend. The infection sources of all the patients were from African countries, and the exported labor workers and travelers for business from malaria endemic areas were the high risk population. The reported time was mainly January, February, November and December (11/13, 84.62%). All the patients were male, and the majority of them (12/13, 2.31%) were 21-60 years old. The median time from onset to seeing a doctor was 2.5 days and the median time from seeing a doctor to being diagnosed was 1.9 day. Six patients (46.15%) were diagnosed as other diseases at the first visit to a doctor, and one patient died of falciparum malaria because of delayed diagnosis. CONCLUSIONS: The incidence of overseas imported malaria presents an uptrend in Qingcheng District. It is necessary to further strengthen the professional training in medical staff to improve the diagnosis and treatment of malaria cases. It is also necessary to strengthen the multisectoral cooperation, establish the surveillance in the high risk population, etc. PMID- 29469457 TI - [Epidemiological characteristics of malaria in Yizheng City from 2000 to 2016]. AB - OBJECTIVE: To explore the epidemiological characteristics of malaria in Yizheng City, so as to provide a reference for formulating the control strategy in the future. METHODS: The data of malaria case reports and prevention and control work in Yizheng City were collected and retrospectively analyzed. RESULTS: Totally 55 malaria cases were found in Yizheng City from 2000 to 2016 with an average incidence of 0.56/105. The malaria cases were local cases from 2000 to 2010 and since 2011 they were all imported cases. CONCLUSIONS: The endemic situation of malarial in Yizheng City is stable and no local infection cases occur in this place for six consecutive years. The imported cases should be paid more attention to in the future control work. PMID- 29469458 TI - [Cryptosporidium infection in Nanjing City from 2015 to 2016]. AB - OBJECTIVE: To investigate the status of Cryptosporidium infection in the population in Nanjing City so as to provide the evidence for the prevention and control of cryptosporidiosis. METHODS: A total of 100 fecal samples were collected from each of three districts (Liuhe, Qixia and Gaochun) and one hospital (Nanjing Zhongda Hospital) in 2015 and 2016 respectively. The fecal samples were detected for Cryptosporidium with microscopy (by using the gold amine phenol-modified acid-fast staining) and the positive samples were detected again for the molecular biology confirming by using the fluorescence quantitative PCR. RESULTS: During the two years, 581 cases of normal population who lived in the city were surveyed and no Cryptosporidium infection was found. Among 202 cases of outpatients with chronic diarrhea, there were 9 Cryptosporidium positive cases with the microscope scanning method (4.46%), and among the 9 cases, 7 cases showed obvious logarithmic amplification curves showing positive Cryptosporidium nucleic acid, but 2 cases without the obvious logarithmic amplification curves, and the Cryptosporidium nucleic acid positive rate was 3.47%. CONCLUSIONS: Cryptosporidium infection is not found in the normal population of Nanjing City, but the Cryptosporidium infection is found in the chronic diarrhea patients. The results imply that we should strengthen the detection of Cryptosporidium in the chronic diarrhea patients, so as to provide the evidence for improving the diagnosis and treatment of cryptosporidiosis.

AB - OBJECTIVE: To understand the status of Toxoplasma gondii infections and the awareness of toxoplasmosis prevention and control knowledge among high-risk populations in Hangzhou City. METHODS: The serum anti-T. gondii antibodies were detected in 100 HIV/AIDS patients, 100 cancer patients, 100 pregnant women and 100 healthy controls, and the awareness of toxoplasmosis prevention and control knowledge was investigated using a questionnaire. RESULTS: The sero-prevalence of T. gondii infection was 31%, 30% and 21% in HIV/AIDS patients, cancer patients and pregnant women, which was all significantly higher than in healthy controls (chi2 = 14.68, 13.96 and 7.56, all P values < 0.01). The pregnant women had a high awareness rate of toxoplasmosis prevention and control knowledge, and the healthy controls had a low awareness rate. In addition, the subjects had a low awareness rate regarding the questions including"Do you know the damages of Toxoplasma gondii infections?", "Do you know that consumption of raw or uncooked meat may cause Toxoplasma gondii infections?", and"Do you know that contact with contaminated soil may cause Toxoplasma gondii infections?". CONCLUSIONS: The sero prevalence of T. gondii infection is high among the high-risk populations in Hangzhou City, including the HIV/AIDS patients, cancer patients and pregnant women, and these high-risk populations have a low awareness rate of some toxoplasmosis prevention and control knowledge. Therefore, it is essential to improve the health education of toxoplasmosis prevention and control knowledge among the high-risk populations, so as to effectively prevent and control human T. gondii infections.

AB - OBJECTIVE: To investigate the status of knowledge, attitude and practice (KAP) of foodborne parasitic diseases among middle school students in Xuzhou City, so as to provide a reference to the health education. METHODS: A total of four middle schools were selected and their students were investigated with the basic information questionnaire and questions of foodborne parasitic diseases. RESULTS: The awareness rates of parasitic diseases, hazards and transmission were 56.50%, 66.33% and 70.50% respectively. The awareness rates of transmission of the diseases in the senior high school students and urban students were higher than those in the junior middle school students and rural students (chi2 = 8.684, 8.470, both P < 0.05). The formation rates of not drinking raw water and not eating raw food were higher among the female students than those among the male students (chi2 = 7.675, 15.230, both P < 0.05). The formation rate of not eating raw food was higher among the senior high school students than that among the junior middle school students (chi2 = 49.276, P < 0.001), and the formation rates of washing hands before meals and not keeping pets were higher among the urban students than those among the rural students (chi2 = 5.833, 13.443, both P < 0.05). Totally 64.83% of the students would not eat food that might be infected with foodborne parasites, and the proportion of girls was higher than that of the boys (chi2 = 11.690, P < 0.05), and 20.5% of the students would suggest others not eating food that might be infected with foodborne parasites, and 81% of the students would plan to get rid of bad habits. CONCLUSIONS: The cognition of foodborne parasitic diseases is poor among the middle school students in Xuzhou City. The health education work on foodborne parasitic diseases should be strengthened.

AB - OBJECTIVE: To investigate the effects and cost of four formulations of niclosamide ethanolamine salt in Oncomelania hupensis snail control in the field in marshland and lake regions, so as to provide the evidence for drawing up the plan of molluscicide using in schistosomiasis endemic areas. METHODS: One drainage channel and one channel without water in the same area with snails in Jiangling County, Jingzhou City were selected as the research fields. The drainage channel was divided into 9 sections, except one section as a blank control group where the natural death rate of snails was observed only, and the remaining 8 sections were taken as the observation groups, where different dosages of 4% niclosamide ethanolamine salt powder, 5% niclosamide ethanolamine salt granules, 25% niclosamide ethanolamine salt suspending agent, 26% metaldehyde and niclosamide ethanolamine salt suspending agent, and 50% niclosamide ethanolamine salt wettable powder were used respectively. The channel without water were divided into 4 sections, except one section as a blank control group, the other 3 segments were taken as the observation groups, where 4% niclosamide ethanolamine salt powder, 5% niclosamide ethanolamine salt granules, and 50% niclosamide ethanolamine salt wettable powder were used respectively. Before and after spraying molluscicide for 7 days and 15 days, the system sampling method was used to observe the effects of snail control. Meanwhile, the unit cost method was used to calculate the costs of the different mulluscicide formulations abovementioned in unit area (1 m2). RESULTS: In the field at the drainage channel, the snail mortality rates of the groups spraying 4% niclosamide ethanolamine salt powder (50 g/m2), 5% niclosamide ethanolamine salt granules (40 g/m2), 25% niclosamide ethanolamine suspending agent, 26% metaldehyde and niclosamide ethanolamine salt suspending agent, and 50% niclosamide ethanolamine salt wettable powder (2 g/m2 and 4 g/m2) for 7 days were 79.52%97.87%, while the rates after spraying for 15 days were 71.00%-96.30%, and compared with those before spraying, the differences were statistically significant (all P < 0.01). For the groups spraying with 2 g/m2 or 4 g/m2 suspending agent as well as wettable powder for 7 days, the snail mortality rates were significantly different (both P < 0.05). In the field at the channel without water, the snail mortality rates of the 3 observation groups after spraying molluscicide for 7 days were 97.14%-100%, while for 15 days were 94.32 %-100%, and compared with the rates before spraying, all the differences were statistically significant (all P < 0.01). The unit costs per 1 m2 of the molluscicide abovementioned were ranged from 0.280 Yuan to 0.416 Yuan. CONCLUSIONS: In marshland area inside embankment, the molluscicide formulations of the powder and granule are suitable for the environments without water or with instability water level, while the molluscicide formulations of the suspended agents and wettable powder are suitable for the water environment. Though the unit cost of powder is the lowest, the molluscicide in this formulation flies away seriously.

AB - OBJECTIVE: To understand the forming cause of the Oncomelania hupensis snail existent non-endemic areas of schistosomiasis (SENEAS), and to verify the conclusion of previous studies, so as to provide the evidence for schistosomiasis monitoring in such areas in Nantong City, Jiangsu Province. METHODS: The controlled field tests were carried out to observe the O. hupensis snails artificially infected by schistosome miracidia in SENEAS. The influence of the soil from SENEAS and the endemic areas on O. hupensis snails artificially infected by miracidia were observed. RESULTS: All the experimental snails could be infected by schistosome miracidia except the smooth-shell snails from Tangyuan Village in the controlled field test environment of SENEAS or the endemic areas. The infection rates of the smooth-shell snails were lower than those of the ribbed-shell snails, but there were no statistically significant differences. The mortality rates of the smooth-shell snails were higher than those of the ribbed - shell snails, which were statistically significant (chi2Xindian = 135.118, chi2Shuangdian = 122.836, chi2Baipu =154.436, chi2Dingyan = 138.288, chi2Control = 151.923, all P < 0.01). There were no significant differences in the infection rates of snails between each test group of the soil from SENEAS and the endemic areas (chi2Rugao = 0.071, chi2Rudong = 0.216, both P > 0.05). Also there was no significant difference between each test group and the control group without soil (chi2 = 7.148, P > 0.05). CONCLUSIONS: It is likely to form the spread of schistosomiasis in SENEAS in Nantong City with sufficient amount of infection source of schistosomiasis imported. It is still necessary to implement the surveillance of schistosomiasis and O. hupensis snails in Nantong City.

AB - OBJECTIVE: To study the expression profiles of circulating microRNAs (miRNAs) in newly-developed advanced schistosomiasis patients. METHODS: Ten healthy controls (Group 1), ten patients with schistosomiasis history (without advanced schistosomiasis, Group 2) and ten patients with newly-developed advanced schistosomiasis (Group 3) were randomly selected from Jiangsu Province. The expression profiles of 570 human related circulatingmiRNAs were measured and analyzed with the Agilent Human microRNAs microarray Rel 12.0. RESULTS: Compared to the healthy controls, four miRNAs were up-regulated, while 16 miRNAs were down regulated in the patients with newly-developed advanced schistosomiasis. Moreover, six miRNAs were up-regulated, while 21 miRNAs were down-regulated in the patients in Group 2. Among of them, the expression level of miR-383 was significantly decreased by 4.23 and 11.82 folds in Group 2 and Group 3, respectively. CONCLUSIONS: There are significant differences among the healthy controls, patients with schistosomiasis history (without advanced schistosomiasis) and the patients with newly-developed advanced schistosomiasisin the expression profiles of circulatingmiRNAs. Moreover, circulating miR-383 might be involved in the development of newly-developed advanced schistosomiasis.

PMID- 29469471 TI - [Progress of molecular detection of Schistosoma]. AB - Schistosomiasis diagnosis plays an important role in the schistosomiasis control. The early detection of schistosomiasis can help to find the infectious source and prevent advanced schistosomiasis effectively. Up to now, serodiagnosis and parasitological diagnosis are used commonly to detect the infection of Schistosoma. As the schistosomiasis control program continues in China, the infection rate and infection intensity of Schistosoma japonicum are decreased significantly, which makes the serodiagnosis and parasitological diagnosis limited for lacking of sensitivity and timeliness. The molecular diagnosis has been developed greatly because of its timeliness, high specificity and sensitivity, which promotes the development and improvement of schistosomiasis diagnosis. In the endemic areas where schistosomiasis is limited and the infection rate is low, the molecular diagnosis provides a potential platform for the early detection and micro detection efficiently. Here, we provide a review that mainly emphasizes the progress of molecular detection of schistosomiasis.

PMID- 29469473 TI - [Role of Rho GTPases in the immune regulation of infection and inflammation]. AB - The Rho subfamily of GTPase belongs to the Ras superfamily of small GTP binding protein, it is a nucleotide dependent protein, which plays a "molecular switch" function in the signal transduction process and control of numerous signaling pathways. Rho protein has many biological effects on cytoskeleton or target proteins as a signal converter in signal transduction, such as the regulation of membrane transport function, cell migration, cell adhesion, and cell proliferation. It also plays a very important role in the infection and immune inflammation of the body. Rho protein is widely distributed in related immune cells, such as T cells, B cells, NK cells and so on. When the body is infected by microorganism, the immune inflammatory reaction will be regulated through a series of signal transduction mechanism, and Rho GTPases signal transduction mechanism is one of the important signal pathways. In this paper, we conclude that Rho GTPases how to regulate the body's immune response through its signal pathway, and ultimately affect the body's immune response.

One patient died on 10 January 2007 because of severe clinical symptoms after hospitalization. The second case was initially misdiagnosed as influenza in primary health and medical institution. The patient's condition quickly worsened and died of Plasmodium falciparum infection on 5 March 2011. The third patient belonged to "non-identity" person, and there were no detailed information and epidemiological history on admission, which resulted in the delayed diagnosis, disease exacerbation and death. In conclusion, the health education should be provided to the people who return from Africa and also to medical workers in order to reduce the mortality of falciparum malaria. PMID- 29469476 TI - [Strengthening the control of goat schistosomiasis to facilitate the progress towards elimination of schistosomiasis in China]. AB - Although great success has been achieved in schistosomiasis control, schistosomiasis japonica remains a publichealth concern in China. Schistosoma japonicum is found to naturally infect over 40 mammalian animals. The implementation of the integrated schistosomiasis control strategy emphasizing infectious source control since 2004, which integrates replacement of bovines with machines, breeding domestic animals in fences, building safe pastures and chemotherapy of infected bovines, results in a clear-cut reduction in the prevalence of S. japonicum infection in both humans and bovines, as well as the areas of infected snail habitats, and the national schistosomiasis control program is moving from transmission control towards transmission interruption and elimination. It has been found that goat is highly susceptible to S. japonicum infection, and previous epidemiological data have shown a high prevalence of infection in goat. However, the role of goat in the transmission of schistosomiasis japonica has not been paid much attention, and there are few systematic surveys to evaluate the role of goat in schistosomiasis transmission in China to date. Professor Liang Yousheng's group investigated S. japonicum development and reproduction (egglaying) in goat body, environmental contamination by goat feces, and the effect of temperature and humidity on the survival of S. japonicum eggs in goat feces. Their findings further demonstrate the role of goat in the transmission of schistosomiasis japonica. In addition, they proposed, based on their findings and previous reports, that the management of goat should be integrated into the national schistosomiasis control program in China, since goat is virtually one of the major infectious sources of schistosomiasis japonica in China. Moreover, this group improved the fecal hatching test and optimized the parasitological technique for diagnosis of S. japonicum infection in goats. These innovative studies fill in the gaps of goat schitsosomiasis japonica research in China, and the research outcomes will enrich the currently implemented integrated schistosomiasis control strategy emphasizing infectious source control, and are believed to play a critical role in schistosomiasis elimination in China. Since schistosomiasis seriously affects goat husbandry development and local famer income, and goat has become a major infectious source of schistosomiasis japonica in China, the control of goat schistosomiaiss will facilitate the progress towards the elimination of schistosomiasis in China, and the following research priorities are suggested: (1) to emphasize the control of goat schistosomiasis, and to integrate the comprehensive management of goat into the national schistosomiasis control program in China; and (2) to develop new techniques, products and interventions for the control of goat schistosomiasis. PMID- 29469477 TI - [Role of goat in transmission of schistosomiasis japonica III Development of goat feces collector and optimization of fecal hatching technique]. AB - OBJECTIVE: To develop a simple, feasible goat feces collector to improve the collection accuracy and integrity of goat fecal samples without pollution, and to modify the miracidium hatching test with a plastic tube to achieve simple, standard and comparative procedures, so as to provide technical support for pathogenic diagnosis and scientific research of goat schistosomiasis japonica. METHODS: According to the body features of goat in marshland regions, a goat fecal collector, which was made of coarse fabric cottons, was devised, which was able to be fixed onto the goat buttocks and avoid urine pollution. Prior to miracidium hatching test, the goat fecal samples were pieced by using a mechanical method instead of the conventional artificial piecing method, and the effect of mechanical piecing treatment on miracidium hatching was evaluated. A filter membrane was added between the tube and rubbery ring to block the floater in fecal residues into the tube. The effects on miracidium hatching by using thin fat-free cotton, thick fat-free cotton, nylon gauze at 100 pores/25.4 mm2 and 150 pores/25.4 mm2 were compared. RESULTS: The goat feces collector was composed of foreleg fixing garment, hindleg fixing garment and stool bag. The functions of the fixing garment were as a fixed collector to allow non-shift and tolerance of weight during goat activity, while the major function of stool bag was in storage of stool. The goat activity did not affect by the use of collector, and all fecal samples were excreted to the bag. This collector was easy to perform and could avoid urine pollution, which was reusable after cleaning. Prior to miracidium hatching, the goat fecal samples, together with water, were pieced at 18000 to 23000 r/min for successive three times in a cooking machine, of 10 s each time at an interval of 5 s. Mechanical piecing had no clear-cut effect on miracidium hatching of eggs in fecal samples. A total of 541, 620, 344 and 211 miracidia were detected by using the miracidium hatching test with nylon gauze at 100 pores/25.4 mm2 and 150 pores/25.4 mm2, thin fat-free cotton and thick fat-free cotton respectively, indicating a better detection efficacy by using nylon gauze at 100 pores/25.4 mm2 and 150 pores/25.4 mm2. CONCLUSIONS: The goat fecal collector is a easy-to-perform, accurate, unpolluted and reusable device to collect goat feces, which is suitable for pathogenic diagnosis of goat schistosomiasis. Mechanical piecing and use of nylon gauze at 150 pores/25.4 mm2 allow a simple, accurate and stable technique for parasitological diagnosis of schistosomiasis japonica, which provides a reliable tool for schistosomiasis control and research. PMID- 29469478 TI - [Role of goat in transmission of schistosomiasis japonica III Effect of temperature and humidity on survival of eggs in goat feces and egg survival in natural environments]. AB - OBJECTIVE: To investigate the survival of Schistosoma japonicum eggs in goat feces in natural marshlands and the factors affecting its survival, so as to provide evidences for understanding of the role of eggs in goat feces in the transmission of schistosomiasis and the development of the interventions pertaining to disease control and elimination. METHODS: The goat animals of schistosomiasis japonica were modeled in laboratory, and the feces of infected goat were collected. In laboratory, the effects of environmental temperature and water content in goat feces on egg hatching were evaluated, and in the field, the effect of duration of goat feces on marshland on egg hatching and the effect of direct sunshine on egg survival were evaluated. RESULTS: At 25 degrees C in laboratory, the hatching rate of eggs in goat feces washigh-positively correlated with the water content in goat feces (r = 0.87). If the water content reduced to 7.6% in goat feces, the eggs in goat feces lost the ability to hatch. Under the same water content in goat feces, the hatching rate of eggs gradually decreased with the extension of the duration of exposure of goat feces to -5 degrees C, which reduced to 0 following 5 h exposure. At 5, 15 and 25 degrees C, the hatching rates of eggs gradually decreased with the extension of the duration of exposure of goat feces, and themiracidium hatching ratesof eggs were 2.3%, 5% and 0.9% respectively following the exposure for 52 d. At 35 degrees C, the hatching rate of eggs gradually decreased with the extension of the duration of exposure, which reduced to 0 following 13 d exposure. In winter (-2-10 degrees C), the hatching rate of eggs gradually decreased with the extension of the duration of exposure of goat feces on marshlands, which reduced to 0 after 21 d of exposure, and in spring (16-19 degrees C), the hatching rate of eggs gradually decreased with the extension of the duration of exposure of goat feces on marshlands, which reduced to 0.9% after 5 d of exposure. At the same time point on the same marshland, the hatching rate of eggs in goat feces exposed to marshlands with direct sunshine was lower than that without direct sunshine. CONCLUSIONS: The survival of S. japonicum eggs in goat feces is associated with environmental temperature and water content (humidity) in goat feces, and the temperature and humidity are major natural factors affecting egg hatching. PMID- 29469479 TI - [Role of goat in transmission of schistosomiasis japonica III Environmental contamination by goat feces and prediction of environments at high risk of S. japonicum infection]. AB - OBJECTIVE: To quantitatively estimate the range and area of environmental contamination by the feces of Schistosoma japonicum-infected that were freely grazed, so as to provide the theoretical evidence for the scientific assessment of the role of the freely grazed goat in the transmission of schistosomiasis japonica and development of control strategy. METHODS: All the fecal samples excreted by the infected goat at daytime (12 h) were collected by using a self made goat fecal collector, weighed and counted. The quantity and dispersal of the feces excreted by the freely grazed goat at daytime under a natural condition were investigated, and the walking route and speed of the freely grazed goat at daytime were recorded with a multifunction GPS data logger. The maximum range and area of the environment contaminated by the feces of the freely grazed goat at daytime were estimated, and the maximum range and area of the Oncomelania hupensis snails that may be infected by the schistosome miracidium released from the eggs in the fecal samples of the freely graze goat at daytime were calculated. RESULTS: During the walking along the marshland at daytime (12 h), the quantity of the feces execrated by the freely grazed infected goat was (232.8 +/- 39.8) g per goat, and the fecal samples were composed of (819.2 +/- 152.1) pellets. The goat had a mean walking speed of (0.522 7 +/- 0.099 7) km/h, and the longest distance, largest radius and largest range of walking activity were (6.272 4 +/- 1.195 8) km, 3.136 2 km and (3 191.113 0 +/- 1 189.709 4) hm2 at daytime, respectively. The area of the snails that may be infected by the miracidium released from the eggs in the fecal samples of the freely graze goat (range of key regions for infected snails detection and control) at daytime was estimated to be (3 210.717 5 +/- 1 190.907 3) hm2. CONCLUSIONS: The intensity of environmental contamination by the eggs in the fecal samples of the freely grazed goat is linked to the number of infected goat. The contamination range caused by the feces of the freely grazed goat with fixed fences is relatively stably kept within the walking range at day-time, and the range and area of goat fecal contamination is associated with the number of households that breed goat and the distribution of goat fence. The area of the snails that may be infected by the miracidium released from the eggs in the fecal samples of the freely graze goat is larger than the area of setting contaminated by the eggs in the goat feces, indicating that the range of infected snail examination and control is larger than the range of goat feces detected.

AB - OBJECTIVE: To describe the growth and development of Schistosoma japonicum in goat and the intensity and temporal distribution of eggs excreted by goat feces, so as to provide baseline data for the control and elimination of the role of goat in the transmission of schistosomiasis. METHODS: The goat animal models of schistosomiasis were established, and stool samples were collected for parasitological examinations. The number of adult worms recovered, variation of schistosomes in goat at different time points post-infection, number of eggs in schistosomes, variation in number and temporal profiles of eggs excreted from goat feces were observed. RESULTS: Of the 6 schistosome-infected goat, 415 adult worms were recovered, with a mean adult worm recovery of 34.58% (range, 23.00% to 45.50%). Among the 5 goat infected with 200 cercariae each, 47, 93, 77, 74 and 73 adult worms were recovered 2, 5, 8, 11 and 14 months post-infection, respectively. There were (200.00+/-42.33), (226.20+/-45.88), (168.20+/-25.85), (183.80+/-55.13) and (190.80+/-53.53) eggs detected in female schistosomes. The mean prepatent period of eggs excreted by 10 infected goat was (37.7+/-3.02) d. From 2 to 14 months post-infection, 7 batches of goat feces were hatched, and there were 30, 23, 14, 1 and 2 times for miracidium intensity of "++++", "+++", "++", "+" and "-", respectively, with 42.86%, 32.86%, 20.00%, 1.43% and 2.86% constituent ratios of miracidium intensity. CONCLUSIONS: Approximately 1/3 S. japonicum cercariae may develop to adults in goats post-infection, and the prepatent period of eggs is (37.7+/-3.02) d. There is no remarkable decrease seen in the number of adult worms, eggs in female schistosomes and eggs in goat feces within 14 months post-infection. Our findings suggest a long duration for infected goat in the transmission of schistosomiasis, and there is no evidence to prove the "self-cure" phenomenon in goat, indicating that goat is an important source of infection for schistosomiasis japonica.

AB - OBJECTIVE: To analyze the construction and operation status of management system of laboratories of schistosomiasis control institutions in Hubei Province, so as to provide the reference for the standardized detection and management of schistosomiasis laboratories. METHODS: According to the laboratory standard of schistosomiasis at provincial, municipal and county levels, the management system construction and operation status of 60 schistosomiasis control institutions was assessed by the acceptance examination method from 2013 to 2015. RESULTS: The management system was already occupied over all the laboratories of schistosomiasis control institutions and was officially running. There were 588 non-conformities and the inconsistency rate was 19.60%. The non-conformity rate of the management system of laboratory quality control was 38.10% (224 cases) and the non-conformity rate of requirements of instrument and equipment was 23.81% (140 cases). CONCLUSIONS: The management system has played an important role in the standardized management of schistosomiasis laboratories. PMID- 29469484 TI - [Correlation between malaria epidemic incidence and some natural and social factors in high incidence areas of Shandong Province]. AB - OBJECTIVE: To explore the association between malaria epidemic situation and some natural and social factors in high-incidence areas of Shandong Province, so as to provide evidences for malaria elimination in these areas. METHODS: Twenty towns of 10 counties (cities, districts,) in the high incidence areas of malaria in Shandong Province were selected as the study sites, and the residents in the study sites were investigated by questionnaires with one household as a unit, so as to understand the related natural and social factors. In addition, the malaria epidemic data in the study sites from 2006 to 2010 were collected, and the correlation between these factors and the epidemic situation of malaria was analyzed by Spearman rank correlation and multiple stepwise regression. RESULTS: The square root of malaria incidence rate (Y) was negatively related to the rate of households using insecticide (X3), and the rate of households using screen doors and windows (X4) (both P < 0.05), but was positively related to the rate of housing surrounding water environment and exposure ratio (X6) (both P < 0.05). The regression equation established was Y = 0.032X5 + 0.048X6-0.495, R2 = 0.973. CONCLUSIONS: Malaria incidence is obviously associated with some natural and social factors. The measures such as clearing the breeding place of mosquito, protecting the exposure population at nightfall, as well as using door-window screen and repellents correctly, can effectively control malaria. PMID- 29469485 TI - [Changes and significance of inflammatory cytokines in sera of mice chronically infected with larvae of Echinococcus granulosus]. AB - OBJECTIVE: To investigate the levels of cytokines in the sera of mice chronically infected with the larvae of Echinococcus granulosus, and explore the mechanisms of immune regulation against parasite infection. METHODS: The protoscoleces were isolated from the livers and lungs of sheep infected with E. granulosus, and then inoculated intraperitoneally to BALB/c mice (2 000 for each mouse), to establish the mouse model of E. granulosus infection. The mice in the control group were injected intraperitoneally with an equal volume of PBS. The sera of both control and infected mice were collected to test the levels of multiple cytokines by using the Cytometric Bead Array (CBA) 5 months post-infection. RESULTS: In contrast to the control group, the multiple cysts were found in the abdominal cavity, livers and lungs of the infected mice. Moreover, the levels of inflammatory cytokines such as IL-17A, IL-6, IFN-gamma, MCP-1, IL-12P70 and TNF alpha in the sera of the infected mice were significantly higher than those in the control group (t = 2.713-9.255, all P < 0.05) while the levels of anti inflammatory cytokine IL-10 were elevated post-infection (t = 3.936, P < 0.001). CONCLUSIONS: Higher inflammatory cytokines in the mice chronically infected with the larvae of E. granulosus, may benefit for the limitation of parasite growth.

PMID- 29469488 TI - [Cloning, expression and serological evaluation of H3 protein from Echinococcus granulosus]. AB - OBJECTIVE: To clone and express the basement membrane specific heparan sulfate proteoglycan core protein (H3), and to evaluate its effect in detection of human cystic echinococcosis (CE). METHODS: The H3 gene immunoscreened from the cDNA library was cloned into pGEX-4T vector. The recombinant plasmid pGEX-3X-AgB8/3 was transformed into Escherichia coli BL21 strains and induced by isopropyl-beta D-thiogalactopyranoside (IPTG). Then the expressed recombinant protein was purified by affinity chromatography and its effect in the detection of CE was evaluated by ELISA. Meanwhile, the effects of H3 and two antigens that the research group prepared before (purified HCF and rAgB8/2) in CE detection were compared. RESULTS: The plasmid pGEX-4T-H3 was successfully constructed and H3 was successfully expressed in prokaryotic cells. The sensitivities of the recombinant H3, purified HCF and rAgB8/2 in CE detection were 84.0% (68/81), 90.1% (73/81) and 77.8% (63/81) respectively, and there was no statistical difference among them (chi2 = 4.58, P > 0.05). The cross reactions of recombinant H3 with the sera of the patients with CE, cysticercosis and schistosomiasis were 63.3% (19/30), 16.7% (5/30) and 5.0% (1/20) respectively, and the cross reaction was 0 with the sera of healthy people. The specificities of recombinant H3, purified HCF, and rAgB8/2 were 80.8% (105/130), 71.5% (93/130) and 82.3% (107/130) respectively, and there were no statistical difference among them (chi2 = 5.71, P > 0.05). CONCLUSIONS: The recombinant H3 is a potential diagnostic antigen for CE detecting. PMID- 29469489 TI - [Investigation on human Toxoplasma gondii infections in Nanchang City in 2014]. AB - OBJECTIVE: To investigate the endemic situation of human Toxoplasma gondii infection in Nanchang City in 2014 and analyze the influencing factors, so as to provide the evidence for control measures. METHODS: The high-risk population of T. gondii infection in Nanchang City was collected as an experiment group, and a control group was settled with the ratio of 1?1. The serum tests and epidemiology surveys were conducted simultaneously, and the influencing factors were analyzed. RESULTS: The total positive rate of human T. gondii was 5.17% (124/2 400) among the whole population in Nanchang City in 2014. The positive rate was 7.50% (90/1 200) in the experiment group and 2.18% (34/1 200) in the control group, and the difference was significant (chi2 =26.668, P<0.05). The results of univariate analysis indicated that different dietary habits and health habits were closely related to the infection of T. gondii (chi2 =16.522, 64.954, both P<0.05). The result of Logistic analysis showed that the risk factors of T. gondii infection were occupation, educational levels, raising cats, contacting animals or raw meat, and eating raw or uncooked beef. CONCLUSIONS: The high risk population of T. gondii infection is the key population of the toxoplasmosis control. Unhealthy dietary and living habits are key influencing factors of toxoplasmosis, and the related health education and surveillance work should be strengthened.

AB - OBJECTIVE: To understand the changes of schistosomiasis epidemic situation, so as to provide the evidence for formulating schistosomiasis control strategy in the Hexi reservoir area. METHODS: From 2012 to 2015, Xinyuan Village, Meishan Town in the north entrance of Hexi reservoir was selected as a monitoring site. According to the requirements of the monitoring program of schistosomiasis surveillance in Zhejiang Province, the Schistosoma japonicum infection was investigated by using the serological screening (IHA), and the basic situation of the surveillance site was also investigated. RESULTS: From 2012 to 2015, 167 environments (21.68 hm2) were surveyed, and 2 slices (0.1 hm2) were found with Oncomelania hupensis snails. The detection rate of frames with snails was 0.12%, and the living snail density was 0.0192 snails per 0.1 m2. Totally 374 snails were dissected and no schistosome infected snails were found. A total of 970 local residents and 8 748 mobile people were investigated with the serological tests, and no schistosome infected people were found. In addition, 3 085 cattle were investigated and no infected ones were found. CONCLUSIONS: The schistosomiasis epidemic situation is stable in the Hexi reservoir area, but we still should strengthen the monitoring of imported source of infection and snail status, and increase the efforts of environmental transformation.

AB - OBJECTIVE: To explore the size changes of erythrocytes infected with Plasmodium malariae, so as to improve the basic-level experimenters' microscopy capabilities for P. malariae identification in thin blood smears. METHODS: The microscopic features of erythrocytes infected with P. malariae in thin peripheral blood smears were observed, and a microscope image processing software was used to measure and analyze the diameter changes of the erythrocytes infected with P. malariae. RESULTS: The diameter of erythrocytes infected with P. malariae decreased significantly compared with that of the normal erythrocytes. The three parameters in this study: the diameter of erythrocytes, the value of diameter variation, and the ratio of diameter variation varied at different developmental stages of P. malariae, and the differences were statistically significant (all P < 0.01). The variances of the three parameters grouped by different cases or different developmental stages in different cases were analyzed, all showing statistically significant differences (all P< 0.01). CONCLUSIONS: All the developmental stages of P. malariae will cause the decrease of the diameters of infected erythrocytes in peripheral blood smears, but the influence on the diameter of erythrocytes, value of diameter variation, and ratio of diameter variation varies at different developmental stages in different cases.

AB - OBJECTIVE: To analyze the results of assessment and authentication of malaria elimination of 7 county-level cities and districts in Changzhou City, Jiangsu Province, and explore the suitable monitoring methods for malaria after the elimination in this region, so as to provide the evidence for formulating and adjusting the malaria elimination strategies and measures. METHODS: The data from the network reports of malaria epidemic situation, blood examinations of febrile patients, epidemiological questionnaires of malaria cases, investigation of epidemic focuses and disposal tables were collected and analyzed in Changzhou City from 2009 to 2014. The clinicians were assessed with the closed-book written examinations for their ability of the diagnosis and treatment of malaria. The inspection personnel were assessed by the microscopical examinations of Plasmodium. Totally 30 negative blood slides were reviewed. In the natural village where the last local case of malaria was located, 200 blood filter papers were collected for gene detection of Plasmodium. RESULTS: From 2009 to 2014, 145 malaria cases were reported in Changzhou City. Totally 170 638 febrile patients received blood detections for malaria, of which 137 cases were positive and the positive rate was 0.08%. The majority of malaria cases were imported except 8 local malaria infection cases in 2009 and 2 local malaria infection cases in 2010. Four of seven county-level cities (districts) gained an average score of 20 points on the microscopical examinations of Plasmodium. Liyang City got a minimum average score of 18.8 points. In capacity assessment of malaria diagnosis and treatment, Liyang City gained the highest average score of 19.8 points, and Qishuyan District got the lowest average score of 18.0 points. The malaria elimination assessment scores of the 7 county-level cities (districts) were all above 93 points. Four county-level cities (districts) (Xinbei District, Wujin District, Liyang City, and Jintan City) carried out the active case detections. A total of 731 cases were detected and the results were all negative. Liyang City in 2012, Zhonglou District and Jintan City in 2013, Tianning District, Qishuyan District, Xinbei District and Wujin District in 2014, passed the malaria elimination assessment at county (district) level, respectively. CONCLUSIONS: All the 7 county-level cities (districts) of Changzhou City have passed the malaria elimination assessment at a high score. After the malaria elimination, the monitoring should continue to consolidate the achievements.

AB - OBJECTIVE: To observe the changes of serum gamma-glutamyl transpeptidase (GGT) levels before and after the pathogen treatment in patients with subclinical schistosomiasis, and explore its clinical value in the diagnosis and treatment of subclinical schistosomiasis. METHODS: Totally 109 patients with subclinical schistosomiasis, who were found in the endemic investigation of schistosomiasis in Ezhou City, were selected as the investigation subjects, and then they were treated with praziquantel. The serum GGT levels of the subjects before and after the treatment were detected and compared. RESULTS: Before the treatment, the average value of the GGT levels of the 109 patients was (48.1 +/- 45.9) IU/L, among which, the GGT levels of 69 cases (63.3%) were normal, and the levels of 40 cases (36.7%) were increased. After the treatment, the average GGT level of the patients was (32.1 +/- 23.4) IU/L, which decreased by 33.3% comparing with that before the treatment, and the difference had a statistical significance (U=2.17, P = 0.01). The GGT levels of 65 patients decreased in different degrees. Among the 40 patients whose GGT levels had increased before the treatment, the GGT levels of 31 ones returned to the normal. CONCLUSIONS: The GGT level detection can accurately reflect the liver function in the patients with subclinical schistosomiasis, and also it has certain clinical application value to judge the liver function damage and recovery of the patients before and after the pathogen treatment.

AB - This review describes the major species, number, breeding pattern, ratio of fenced to freely grazed goat, susceptibility to Schistosoma japonicum, pattern of S. japonicum infection, infection rate, intensity of infection, fecal contamination of goat that were bred in 5 marshland and lake provinces of Hunan, Hubei, Jiangxi, Anhui and Jiangsu, and two mountainous provinces of Yunnan and Sichuan, and demonstrates the associations of infected goat distribution with the distribution of infected Oncomelania hupensis snails and humans. Considering the huge number of goat which were predominantly grazed freely in marshland and lake endemic regions of China, the high infection rate, numerous environmental pollution by goat feces, as well as the close correlation between the infected goat distribution and infected snail distribution, goat is considered as a major infectious source for schistosomiasis japonica in China, and to play a critical role in the transmission of the disease. Since the control of schistosomiasis in animals is critical to schistosomiasis interruption and elimination, it is suggested that the integrated management of goat schistosomiasis should be included in the national schistosomiasis control program of China.

AB - Relevant projects carried out within the Yangtze River economic belt on the impact of schistosomiasis epidemic and transmission are important issues for "ecological priority" in the process of implementing the strategy. The key problems of schistosomiasis epidemic risk, epidemic happening repeatedly, difficulty of rehabilitating Oncomelania hupensis snail control and schistosomiasis prevention forest, lag of evaluation system and platform construction, lack of basic research, et al. were analyzed in the Yangtze River economic belt taking "ecological priority" as the basis in this paper. Then corresponding countermeasures to these challenges were put forward so as to provide the reference for the national forestry schistosomiasis control programs, which include: execution of the comprehensive prevention and control strategy, scheming of the new round of forestry schistosomiasis control programs, strengthening schistosomiasis prevention and control, promoting productivity in existing forestry to consolidate and improve the achievements of previous forestry schistosomiasis control programs, and promoting the intensity of technological innovation to improve the technological level of forestry schistosomiasis control programs. PMID- 29469512 TI - [Value and evaluation on multidisciplinary treatment of advanced schistosomiasis]. AB - Advanced schistosomiasis, encompassing a wide range of pathologic entities and multi-complications, poses a serious threat on the patients' health. Through comprehensive analysis and evaluation on related aspects regarding clinical classification, main methods of auxiliary examination and treatment (including types of surgical procedure) of advanced schistosomiasis, we think that the individual based multidisciplinary comprehensive treatment according to varying conditions of patients is the most optimal treatment mode of advanced schistosomiasis. It is further proposed that multidisciplinary collaborative diagnosis and treatment system should be undoubtedly established, multidisciplinary case discussions be regularly organized, and treatment expert teams be stably formed, in order to significantly improve the level of diagnosis and treatment of advanced schistosomiasis, so as to reduce the misdiagnosis and improve the therapeutic effect in advanced schistosomiasis control. PMID- 29469513 TI - [Surveillance of schistosomiasis in People's Republic of China in 2015]. AB - OBJECTIVE: To analyze the investigation data of the national schistosomiasis surveillance sites in 2015, so as to provide scientific evidences for schistosomiasis control, elimination and surveillance. METHODS: According to National Schistosomiasis Surveillance Programme (version 2014), 457 surveillance sites were selected, and the investigation data in residents, floating population, domestic animals and Oncomelania hupensis snails were collected and analyzed from four types of endemic counties. RESULTS: A total of 4 468 seropositive cases were detected from 133 350 residents, among which 4 457 residents with seropositive results received the etiological tests, and 71 of them were identified with positive results. Most of them were fishermen and farmers in the middle and old-aged group. The schistosomiasis infection rate was 0.05% in local population. Totally 977 seropositive cases were examined from 85 047 migrant individuals, and 16 positive cases were found out from 966 individuals who took etiological tests, which showed the schistosomiasis infection rate was 0.02% in floating population. Imported cases were found among floating people in four provinces, namely Zhejiang, Hunan, Hubei and Anhui provinces. No acute schistosomiasis cases were reported. A total of 13 406 head of cattle received examinations and only 5 were determined as stool positives. The cattle infection rate was 0.04%. The snail survey covered an area of 22 295.13 hm2 and snails were found in an area of 7 426.63 hm2, including 3.47 hm2 newly detected area with snails. No schistosome-infected snails were found. CONCLUSIONS: Based on the collected data from 457 national schistosomiasis surveillance sites of China, the Schistosoma japonicum infection rate is 0.05% in local population which maintains a stably descending trend. In floating population, there are imported schistosome-in-fected persons. Cattle are still a vulnerable species infected with schistosome. Although no infected snails are found, snails are widely distributed in endemic areas. Some provinces detect areas with snails for the first time or the reproduction of snails. The staff in endemic provinces should carry out the surveillance work according to National Schistosomiasis Surveillance Programme (version 2014) to improve the surveillance system, and enhance the sensibility and effectiveness of surveillance work. PMID- 29469514 TI - [Analysis of characteristics of medical assistance to advanced schistosomiasis patients in Hunan Province, 2015]. AB - OBJECTIVE: To understand the current distribution and characteristics of advanced schistosomiasis patients who accepted medical assistance in Hunan Province in 2015, so as to provide the evidence for perfecting the policy and measures of the medical assistance to advanced schistosomiasis patients. METHODS: The patients who had been diagnosed as advanced schistosomiasis were verified and confirmed according to the standard of the medical assistance to advanced schistosomiasis patients in Hunan Province in 2015. The epidemiological survey was conducted to investigate the demographic characteristics, history of diagnosis and treatment, and medical assistance to these persons. RESULTS: There were 3 850 advanced schistosomiasis patients who accepted the medical assistance in Hunan Province in 2015, and among them, 2 664 patients were male (69.19%), and 1 186 were female (30.81%). Most of them (92.82%) came from the main schistosomiasis endemic areas, such as Yueyang, Changde and Yiyang. There were 2 369 cases of ascites (61.53%), 1 466 cases of splenomegaly (38.08%), 15 cases of colon proliferation and dwarf (0.39%). The mean age of advanced schistosomiasis patients who accepted the medical assistance was (62.94 +/- 11.67) years old, with 64.31% of them being more than 60 years old. The age of initial diagnosis of advanced schistosomiasis was (53.85 +/- 21.32) years old, and it was concentrated in 40-60 years old (68.57%). The mean duration of advanced schistosomiasis was (9.58 +/- 10.06) years, and it was mainly distributed in 10 years (75.95%). The mean duration from initial diagnosis of schistosomiasis to advanced schistosomiasis was (22.33 +/- 14.20) years. The priority of the medical assistance to advanced schistosomiasis patients was given to the county hospitals (76.57%); and the effective rate of assistance was 94.46%. Totally 86.57% of the patients with advanced schistosomiasis got the medical insurance (rural cooperative medical care, urban medical care, etc.). CONCLUSIONS: The burden of the medical assistance to advanced schistosomiasis patients is still heavy because of many patients and low cure rate in Hunan Province. The ascites patients and high age patients should be the important objects of the medical assistance. PMID- 29469515 TI - [Application of degree of portal systemic shunting in assessing upper gastrointestinal bleeding in patients with schistosomiasis cirrhosis]. AB - OBJECTIVE: To discuss the application of the degree of portal systemic shunting in assessing the upper gastrointestinal bleeding in patients with hepatic schistosomiasis. METHODS: Thirty-three patients with upper gastrointestinal bleeding caused by hepatic schistosomiasis (a bleeding group) and 29 schistosomiasis cirrhosis patients without bleeding (a non-bleeding group) were enrolled as investigation subjects in Jinshan Hospital. The subjects were scanned by the 128 abdominal slice spiral CT. The portal systemic shunting vessels were reconstructed by using thin slab maximum intensity projection (TSMIP) and multiplanar reconstruction (MPR). The degrees of the shunting vessels of the subjects were evaluated and compared, and the relationship between upper gastrointestinal bleeding and the degree of the shunting was analyzed. RESULTS: In the bleeding group, the occurrence rates of the shunting vessels were found as follows: 86.4% in left gastric varices, 68.2% in short gastric varices, 50.0% in esophageal varices, 50.0% in para-esophageal varices, 37.9% in gastric varices, 69.7% in gastric-renal varices, 51.5% in spleen-renal varices, 25.8% in abdominal wall varices, 15.2% in omentum varices, 63.6% in para-splenic varices, 34.8% in umbilical varices, 40.9% in retroperitoneal-paravertebral varices, and 36.4% in mesenteric varices. In the bleeding group, the occurrence rates and the degree of shunt were significantly higher than those in the non-bleeding group in esophageal varices, esophageal vein, left gastric vein and gastric varices (all P < 0.05). CONCLUSIONS: CT portal vein reconstruction can accurately display the location, degree and walking of all kinds of shunting vessels. Esophageal varices, esophageal vein, left gastric vein and gastric varices can accurately predict the risk of upper gastrointestinal bleeding in patients with hepatic schistosomiasis. The patents with higher degree of the shunting vessels have a higher risk of gastrointestinal bleeding.

AB - OBJECTIVE: To investigate the Oncomelania hupensis snail control effect of schistosomiasis control engineering in marshland within Wuhan City. METHODS: The engineering measures including surface barrier removal, molluscicide, flatting surface, topsoil stripping, topsoil covering and ditch renovation were applied to transform Hankou marshland. Then the corresponding technical parameters of engineering measures were put forward. The situation of snails was analyzed before and after the transform project. RESULTS: The total length and area of the project were 6 015 m and 87.21 hm2, respectively, including 17.44 hm2 of topsoil landfill, 52.08 hm2 of topsoil covering and 23 new ditches. After the transformation, the average length of the new groove, the groove top width, groove depth, height difference, and the average values of slopes and ditch bottom slope were all increased, while the average values of the width and height of the ditch were decreased. At the same time, the marshland beach surface had a new slope that the embankment was higher than the river and no living O. hupensis snails were found then. CONCLUSIONS: The snail breeding environment in Hankou marshland has been effectively changed by the project. However, the constant monitoring and engineering management are still needed to consolidate the effect. PMID- 29469517 TI - [Distribution features of wild feces in schistosomiasis endemic areas in Jiangling County, Hubei Province]. AB - OBJECTIVE: To understand the spatial distribution characteristics of wild feces in schistosomiasis endemic areas of Jiangling County, Hubei Province and further explore the source of infection efficiently, so as to provide the evidence for the development of corresponding monitoring and response technology. METHODS: In 2011, the fresh wild feces were investigated every two months in the selected 15 villages by the severity of historical endemic in Jiangling County. The schistosome miracidium hatching method was used to test the schistosome infection of the wild feces. The descriptive analysis and spatial analysis were used for the description of the spatial distribution of the wild feces. RESULTS: Totally 701 wild feces samples were collected with the average density of 0.055 6/100 m2, and the positive rate of the wild feces was 11.70% (82/701). The results of the regression analysis showed a positive spatial correlation between the positive rate of wild feces and the rate of human infection, the area with infected Oncomelania hupensis and the number of fenced cattle, and the corrected R2 of the model was 0.58. CONCLUSIONS: The infection rate of wild feces is positively correlated with the rate of human infection, area with infected O. hupensis and number of fenced cattle in space in Jiangling County, so the prevention and control measures could be conducted according to the spatial distribution of the positive wild feces.

AB - OBJECTIVE: To produce a comprehensive transcript dataset of Oncomelania hupensis before and after Schistosoma japonicum infection, so as to provide experimental data for perfecting genetic structural information and excavating related molecular markers of O. hupensis infected by S. japonicum. METHODS: O. hupensis snails were divided into the following 3 groups: one week after S. japonicum miracidium infection, 4 weeks after S. japonicum miracidium infection, and normal condition. Million high-quality reads were obtained from the normalized cDNA of the pooled samples, which were assembled into transcripts. RESULTS: A total of 63 686 unigenes were identified and were classified into 4 main categories, including general functional prediction (15.36%), signal transduction mechanism (11.75%), posttranslational modification (8.89%), and functional unknown (12.20%). CONCLUSIONS: The transcriptome information of O. hupensis snail after the invasion of S. japonicum shows that several genes are significantly up regulated or down regulated expression, and that the availability of transcriptome information might provide a strong foundation for further understanding the schistosome-snail interaction at the molecular level. PMID- 29469519 TI - [Comparative analysis of malaria detection ability of laboratories in Shanghai City from 2012 to 2015]. AB - OBJECTIVE: To compare the application effects of three methods, namely microscopic examination, antigen detection (RDT) and nucleic acid test (PCR) in malaria detection between municipal and districts/counties centers for disease control and prevention in Shanghai, and analyze the malaria detection ability of the laboratories in Shanghai. METHODS: The blood smears, whole blood samples, case review confirmation records and case data of malaria cases and suspected cases in Shanghai from 2012 to 2015 were collected by Shanghai Municipal Center for Disease Control and Prevention, and the detection results were analyzed and compared. RESULTS: A total of 212 samples with complete data were submitted by all districts (counties) in Shanghai from 2012 to 2015, the samples submitted by Jinshan Districts were the most (41.98%), and among the first diagnosis hospitals, those submitted by the tertiary hospitals were the most (82.07%). The submitted samples in the whole year were increased gradually from January to October. All the 212 samples were detected by three methods (the microscopic examination, RDT and PCR) in the laboratory of Shanghai Municipal Center for Disease Control and Prevention, and 167 were tested and confirmed comprehensively as positives, accounting for 78.77%, and 45 were confirmed as negatives, accounting for 21.23%. The samples were detected by the method of microscopy and domestic RDT in the laboratories of the centers for disease control and prevention at district/county level, totally 153 were tested as positives, accounting for 72.17%, 41 were unclassified, accounting for 19.34%, 53 were negative, accounting for 25.00%, and 6 were undetected, accounting for 2.83%. The coincidence of microscopic examination between the report hospitals and the centers for disease control and prevention at district/county level was 78.16%, and the coincidence between centers for disease control and prevention at district/county level and municipal level was 93.20%. The utilization rate of RDT in the laboratory of district/county level was 73.58%. The coincidence of RDT tests between those domestic and imported was 93.59%. Compared with the detection results by municipal center for disease control and prevention, 37 samples were misjudged by the laboratories of district/county level. Almost all (99.37%) of the confirmed malaria cases were imported overseas, including Africa (85.44%), Asia (13.92%) and America (0.63%). CONCLUSIONS: The surveillance after malaria elimination in Shanghai should be carried out by combining with different detection methods and resource integration.

AB - OBJECTIVE: To analyze the epidemiological characteristics of overseas imported malaria reported in Chongqing City from 2011 to 2015, so as to provide the evidence for improving the imported malaria control strategies. METHODS: The epidemiological data of overseas imported malaria cases were collected and analyzed descriptively for the species, original countries, diagnosis and treatment in Chongqing City from 2011 to 2015. RESULTS: A total of 148 overseas imported malaria cases were reported in Chongqing City from 2011 to 2015, in which 96 (65.54%) cases were falciparum malaria, and 37 (24.32%) cases were vivax malaria; 125 (84.46%) cases were infected in Africa, and the rest of 23 (15.54%) cases were infected in Southeast Asia. Most of the patients were 30 to 50 years old male workmen, and the ratio of male to female was 11.42:1. There was no obvious seasonal distribution among the reported timelines of the cases; however, there were two small peaks from June to August and from January to February. The median interval time of imported malaria cases from malaria onset to see a doctor was 1 day and from seeing the doctor to get malaria diagnosis was 2 days. The patients' first selected institutions were county medical institutions (50 cases, 33.78%), then provincial medical institutions (36 cases, 24.325%) and private doctors (20 cases, 13.51%), and only 79 (53.38%) patients got malaria diagnoses in their first selected institutions. The standard treatment were provided to 142 (95.54%) cases. There were 43 (29.05%) patients had serious complications and three patients were dead. CONCLUSIONS: It is very important to enhance the multi sector's collaboration to establish the collaborative investigation mechanism for screening malaria patients, and strengthen malaria health education for overseas workers and training courses in primary care medical institutions.

METHODS: B16F10 tumor cells were axillarilly injected into the right flank of 20 C57BL/6 mice to establish tumor-bearing mouse models. The next day, the mice were randomly divided into a P.y infection group and control group, 10 mice each group. Each mouse of the P.y infection group was intraperitoneally injected with 1*106 red blood cells including 20% P.y infection red blood cells, and each one of the control group were intraperitoneally injected with 1*106 normal red blood cells of C57BL/6 mice. The time of tumor formation of the mice in the two groups was observed and the tumor volumes were measured. RESULTS: The time of tumor formation in the P.y infection group[ (11.30 +/- 0.21) d]was significantly later than that in the control group [ (10.40 +/- 0.22) d] (P < 0.05). From the tumors could be accurately measured to the study end point, both the tumors of mice in the two groups were growing, and the tumor volumes of mice in the P.y infection group were significantly less than those in the control group at each time point (all P < 0.05). The growth rate of tumors in the P.y infection group [ (71.10 +/- 6.29) mm3/d] was significantly slower than that in the control group [ (302.80 +/- 49.94) mm3/d] (P < 0.05), and the growth rates of tumors everyday in the P.y infection group were significantly slower than those in the control group (all P < 0.05). CONCLUSIONS: The P.y infection can delay the occurrence of tumor and inhibit the growth of melanoma.

RESULTS: The density of B. straminea was 1.04-1.16 g/cm3, and the average value was 1.08 g/cm3. The hydrostatic settling velocity was 2.32-12.92 cm/s. CONCLUSIONS: The eco hydraulics characteristics of B. straminea is different from Oncomelania hupensis, and more attention should be paid to the hydraulic measures for the control of B. straminea. PMID- 29469525 TI - [Comparison of three different methods for isolating RNA from Oncomelania hupensis]. AB - OBJECTIVE: To compare the effects of three kinds of Oncomelania hupensis RNA extraction methods, namely a modified SDS method, TRIzol reagent method, and CTAB method, so as to obtain an economical and efficient method for RNA extraction from O. hupensis. METHODS: The modified SDS method, TRIzol reagent method and CTAB method were applied to extract the RNA from O. hupensis. A nucleic acid protein analyzer was used to measure the concentration and purity of RNA. The yields were calculated by the concentration of the products. The purity was indicated by A260/A280 and A260/A230. The quality of RNA was inspected by 1% agarose gel electrophoresis. The beta-acting gene was selected as the target gene for RT-PCR analysis. RESULTS: The RNA yields obtained by using the three kinds of extraction methods were significantly different (F = 16 895.85, P < 0.01) according to the analysis of variance. The LSD test showed that the yields obtained by using the modified SDS method were the highest, and those obtained by the CTAB method were the lowest. The purity of RNA extracted by the CTAB method was superior to that by the other two methods, and the A260/A280 and A260/A230 ratios of the CTAB method were in the range from 1.8-2.0 and 2.0-2.2. The A260/A230 ratios of the other two methods were both lower than 2.0. The RNA extracted by the modified SDS method had the better integrity. The electrophoresis results showed that the 28S rRNA band, 18S rRNA band and 5S rRNA band were clear, and there was no obvious smear between each band. The RNA obtained by the TRIzol reagent method had no 28S rRNA band, and that obtained by the CTAB method had no 28S rRNA and 5S rRNA bands. The beta-acting gene of the RNA extracted by all the three methods could be amplified by RT-PCR. The costs and time-consuming of the modified SDS method were less than those of the other two methods. CONCLUSIONS: The modified SDS method is an economic and efficient method, and it is suitable for extracting the RNA of O. hupensis, especially for large sample preparation.

PMID- 29469528 TI - [Short - term effects of two kinds of plastic mulch on Oncomelania hupensis snail control in irrigation and drainage ditches in Yunnan Province]. AB - OBJECTIVE: To evaluate and compare the short-term effects of two kinds of plastic mulch on Oncomelania hupensis snail control in irrigation and drainage ditches with snails in Yunnan Province. METHODS: The irrigation and drainage ditches with high density of Oncomelania hupensis snails were chosen as the investigation sites, and then 4 groups were set, namely a colorless plastic mulch group, black plastic mulch group, colorless plastic mulch with molluscicide group and black plastic mulch with molluscicide group. The snail situation of the 4 groups was surveyed before the experiment and 7, 14, 21, 30 days after covering plastic mulch, and the snail death rates were compared among the 4 groups. Meanwhile, the hourly temperatures of soil surface, soil surface under plastic mulch and soil layer 5, 15 cm under the surface as well as the weather situation during the study period were measured and recorded. RESULTS: The average snail mortality rate of the colorless plastic mulch group was only 15.29% that was higher than that of the black plastic mulch group (6.56%) (P < 0.01). The average snail mortality rates of the colorless and black plastic mulch with molluscicide groups were 40.80% and 50.15%, respectively, and there was no statistic difference between them (P > 0.05). Both kinds of plastic mulches could raise the temperature of the soil surface under plastic mulch and the soil layer below it, and the temperature of soil under the mulches increased over the cover time, and the average temperature of the soil surface under the black mulch in 30 days was higher than that under the colorless mulch. CONCLUSIONS: It is not suitable to use plastic mulch only in irrigation and drainage ditches with snails widely in Yunnan Province because of its low effect, and if necessary, the molluscicide should be added. PMID- 29469530 TI - [Percutaneous transsplenic varices embolization in treatment of upper gastrointestinal hemorrhage of schistosomiasis cirrhosis]. AB - OBJECTIVE: To evaluate the application value of percutaneous transsplenic varices embolization (PTSVE) in the treatment of upper gastrointestinal hemorrhage in patients with schistosomiasis cirrhosis. METHODS: Sixteen schistosomiasis cirrhosis patients (12 males and 4 females) with portal hypertension complicated with esophageal and upper gastrointestinal hemorrhage were selected as the investigation subjects, all the patients had been treated by esophageal vein ligation and sclerotherapy, but with bleeding again post-operation. The patients were treated by PTSVE under the guidance of X-ray fluoroscopy. The success rate of PTSVE and the rate of complications were observed. In addition, the patients received PTSVE were reexamined with abdominal CT one month post-operation, and the degrees of varices were compared before and after PTSVE. RESULTS: Fourteen cases (87.50%) were successfully treated with PTSVE. Two cases (12.50%) failed, and one case had an abdominal bleeding 1 week post-operation. The abdominal CT showed the degrees of esophageal varices (P < 0.001), esophageal vein (P < 0.001) and gastric varices (P < 0.001) were significantly decreased in the patients who received PTSVE one month after the operation. CONCLUSIONS: PTSVE is a safe and effective method in the treatment of upper gastrointestinal hemorrhage in the patients with schistosomiasis cirrhosis. PTSVE is especially suitable for the patients with severe liver cirrhosis, significantly bordered liver split, and bared main portal vein and even the branches.

METHODS: A questionnaire survey was conducted in the Armed Police Forces along the Yangtze River in Jiangsu Province, and the investigation content included social demographic data, schistosomiasis prevention knowledge, attitude and behavior. All the subjects were examined for Schistosoma japonicum infection. RESULTS: Totally 376 soldiers were investigated in 2 sites. The total passing rate of schistosomiasis knowledge was 72.87%. The passing rate among different age groups had no significant difference ( chi2 =0.26, P > 0.05). The passing rate of soldiers from endemic areas was significantly higher than that of the soldiers from non-endemic areas ( chi2 =4.71, P < 0.05). The passing rate of officers was significantly higher than that of the soldiers (chi2 = 4.21, P < 0.05). The passing rate of soldiers with the education levels of junior school, high school, college, undergraduate and above increased gradually, with a significant difference (chi2 =8.16, P < 0.05). The soldiers with positive attitude accounted for 93.88%. Among the water contact behaviors, training accounted for 17.55% and participating in the task (such as flood fighting and water work) accounted for 86.44%. When launching, the rate of taking protective measures was 52.93%. The rate of taking protective measures in the knowledge passing group was much higher than that in the knowledge failed group (chi2 =10.55, P < 0.05). The stool was harmlessly treated in the two camps. Among 376 soldiers, the positive rate of blood examinations was 0.53%, but the stool examinations were all negative. CONCLUSIONS: The overall level of knowledge and correct behavior of schistosomiasis prevention in the Armed Police Forces along the Yangtze River still should be improved.

AB - OBJECTIVE: To investigate the prevalence and risk factors of Toxoplasma gondii infection among key populations in Wuxi City, Jiangsu Province, so as to provide evidences for developing preventive and control interventions for T. gondii infection. METHODS: A questionnaire was designed to conduct face-to-face interviews to HIV/AIDS carriers/patients, tumor patients, pregnant women and pet breeders. The blood samples were collected to test anti-Toxoplasma IgM and IgG antibodies by using ELISA method. RESULTS: Totally 404 participants were investigated, and 38 were positive in testing T. gondii antibodies (9.4%), and among these, 37 (97.4%) were IgG positive and 1 (2.6%) was IgM positive. The multivariate logistic regression indicated that age, regularly contacting cats/dogs and being HIV positive were associated with the infection of T. gondii (OR=2.1, 2.6 and 2.3, all P < 0.05). Breeding pets, being HIV positive and being tumor patients were more likely to infect T. gondii than being pregnant (OR = 1.5, 8.1 and 2.8, all P < 0.05). CONCLUSIONS: The high infection rate of T. gondii is observed among key populations in Wuxi City, so that the effective measurements should be taken to enhance the intervention among key populations including immunocompromised people, pet breeders or people having bad dietary habits of eating raw food.

AB - OBJECTIVE: To analyze the laboratory diagnosis results and epidemiological characteristics of imported malaria cases in Chongqing Municipality in 2015. METHODS: According to the Standard Operating Procedures of Malaria Diagnosis Reference Laboratory Manual, all the blood samples collected from the imported malaria patients were detected by microscopy, RDT and nest PCR. Meanwhile, the epidemiological data of the malaria cases were collected from the Parasitic Diseases Information Management System and analyzed. RESULTS: Totally 31 cases of imported malaria were reported in Chonqing Municipality in 2015, among which, there were 2 vivax malaria cases (6.45%), 23 falciparum malaria cases (74.19%), 5 ovale malaria cases (16.13%), 1 malariae malaria case (3.22%). For the 5 ovale cases, three of them were confirmed as Plasmodium ovale wallikeri infection. Among all the cases, 30 cases (96.77%) were from African countries, 1(3.33%) was from Southeast Asia. Thirty patients were male, and 1 was female. All the patients were aged from 23-61 years. There was no obvious seasonality in the case distribution. Both the medians of duration from malaria attack to first visiting a doctor and from first visiting a doctor to diagnosis were 2 days. The medical care units that the patients first visited were mainly county-level units, while those that made the diagnosis were mainly provincial level institutes. CONCLUSIONS: All the malaria cases in Chongqing in 2015 are imported, no local cases have been found, which suggests that this municipality still maintain the malaria elimination state. However, the monitoring and management of imported malaria cases as well as the training on malaria control for related medical staff still need to be strengthened.

AB - OBJECTIVE: To understand the prevalence of Toxoplasma gondii infection and its risk factors among healthy blood donation population in Shijiazhuang City, Hebei Province, so as to provide the evidence for developing effective prevention and control measures. METHODS: A total of 1 630 cases of blood donors in Shijiazhuang City were chosen as respondents, and all the respondents were qualified to the standard of blood donation. The antibodies to T. gondii were detected by using ELISA. The infection rates of T. gondii in blood donation population were compared between/among different genders, ages, occupations, education levels, and places of residence. The risk factors for Toxoplasma infection were surveyed with questionnaires. RESULTS: A total of 1 630 cases of healthy blood donors were investigated, and among which 126 cases were positive in the detection of antibodies to T. gondii and the positive rate was 7.73%. The positive rates between/among the different genders, ages, occupations, and education levels were significantly different (chi2 = 4.36, 13.98, 9.71, 7.65, respectively, all P < 0.05), and the positive rates among different places of residence were not significantly different (chi2 = 1.63, P > 0.05). The questionnaire survey showed that the T. gondii infection was closely related to keeping pets, outside eating frequently, having chafing dish or barbecue, sharing cutting board for cooked and uncooked food, and no the habit of washing hands before meals. CONCLUSIONS: The infection rate of T. gondii is relatively high among the healthy blood donation population in Shijiazhuang region. The cognitive education for T. gondii infection and infection monitoring are the keys to avoid the transfusion infection.

AB - OBJECTIVE: To investigate the association between hepatic fibrosis and anti neutrophil cytoplasmic antibodies (ANCA) in the patients with schistosomiasis. METHODS: Totally 145 schistosomiasis patients confirmed by Jingzhou First People's Hospital during the period of February 2014 to June 2016 were randomly selected as an experimental group, and 100 healthy people during the same period were randomly selected as a control group. The serum samples of the two groups were collected and the level of ANCA was detected by indirect immunofluorescence, and the levels of hyaluronic acid, laminin, procollagen type III, and collagen type IV were detected by radioimmunoassay. The levels of the above indexes of the two groups were compared. RESULTS: The positive rate of ANCA was 28.96% (42/145) in the experimental group and 1.00% (1/100) in the healthy control group, and the difference between them was statistically significant (P < 0.05). The levels of hyaluronic acid, laminin, procollagen type III and collagen type IV in the experimental group were significantly higher than those in the control group, and the differences were statistically significant (all P < 0.05), and the proportions of those with abnormal levels of hyaluronic acid, laminin, procollagen type III and collagen type IV in the experimental group were significantly higher than those in the control group, and the differences were statistically significant (all P < 0.05). In the experimental group, among the 42 patients with ANCA positives, the proportions of those with abnormal levels of hyaluronic acid and laminin were significantly higher than the proportions of those with ANCA negatives, and in the former, the levels of the four indicators of liver fibrosis were all higher than the normal values, and the average levels of hyaluronic acid and laminin in the patients with ANCA positives were significantly higher than those in the patients with ANCA negatives (all P < 0.05). CONCLUSIONS: The patients with schistosomiasis hepatic fibrosis could be positive for the autoimmune antibody ANCA, and ANCA may be associated with the autoimmune process of liver fibrosis.

AB - BACKGROUND: Intermediate Care Units (IMCU) are established in many hospitals to better match the requirements of patient care with respect to their personnel, equipment and other resources. This should relieve Intensive Care Unit (ICU) capacities for more severely ill patients and reduce readmissions to ICU. This study was conducted to investigate the effects of IMCU use on ICU populations. METHODS: This is a retrospective analysis of the German National Registry of Intensive Care from the years 2000 to 2010. RESULTS: We included 39 ICUs with high and 11 ICUs with low IMCU use. Patients in ICUs with high IMCU use were younger (mean age [high vs. low]: 60.5 vs. 64.5 years, P<0.001), while the severity of illness was higher (percentage of ventilated patients during ICU stay [high vs. low ICMU use]: 67.2% vs. 40.2%, P<0.001; patients ventilated >24 hours: 22% vs. 18%, P<0.001; mean therapeutic intervention scoring system-28 (TISS-28) score: 25.7 vs. 23.3, P<0.001). Readmission rates to ICU did not differ between ICU groups ([high vs. low]: 4.5% vs. 4.4%, P=0.25). ICUs with high IMCU use discharged 90.3% of all patients who were discharged to the IMCU or general ward between the regular workday hours of 06:00 and 14:59, while ICUs with low IMCU use discharged 83.8% of all patients discharged to the general ward in the same time period. CONCLUSIONS: The use of IMCUs influences resource utilization of ICUs. Severity of illness and workload was higher in ICUs with high IMCU and more scheduled discharges occurred during the main working hours while readmission rates were similar.

PMID- 29469551 TI - Don't Try This at Home: the FDA's Restrictive Regulation of Home Testing Devices. AB - Over the past forty years, the Food and Drug Administration (FDA) has successfully restricted consumers' access to home-testing applications based on the notion that it should protect individuals from their own reactions to test results. In the 1970s, the FDA briefly denied women access to home pregnancy tests that were identical to those used in laboratories. In the late 1980s and early 1990s, it relied on concerns about consumer responses to HIV status results to justify a categorical ban on applications for HIV home-testing technology. More recently, it placed burdensome restrictions on direct-to-consumer (DTC) genetic testing companies, such as 23andMe, based on fears that consumerswould make irrational medical decisions after receiving genetic variant results. Although the FDA has the statutory authority to ensure the "safety and effectiveness" of medical devices, it has expansively interpreted the term "safety" to encompass considerations of how consumers might use test results provided by purely informative devices. This Noteargues that courts should not give the FDA deference on its broad interpretation of safety" in restricting home testing devices. It documents the evolution of the expertise-based rationale for judicial deference, noting that courts typically provide scientific agencies, including the FDA, "super deference" because of the complicated nature of their work. Ultimately, courts should not defer to the FDA's interpretation of "safety" because it did not use its scientific expertisewhen it considered how consumers might react to HIV home-testing and DTC genetic testing results. Further, the FDA should not have the authority to make decisions based on its view of "safety" because it should not have the power to make value judgments for consumers about whether they should seek their personal medical information.

AB - In the United States, women are routinely forced to undergo cesarean sections, episiotomies, and the use of forceps, despite their desire to attempt natural vaginal delivery. Yet, the current American legal system does little to provide redress for women coerced to undergo certain medical procedures during childbirth. Courts and physicians alike are prepared to override a woman's choice of childbirth procedure if they believe this choice poses risks to the fetus, and both give little value to the woman's right to bodily autonomy. This Note proposes a solution for addressing the problem of coerced medical procedures during childbirth by importing a framework created in Venezuela and Argentina that characterizes this issue as "obstetric violence." First, this Note contains an overview of the shortcomings of the existing American legal framework to address the problem. Second, it explains the advantages of the obstetric violence framework and argues that its adoption in the United States would address many of the failures of the existing system. And third, this Note introduces a few legislative and litigation strategies that can be used to implement this framework in the United States and briefly addresses some of the challenges these strategies may pose.

AB - In recent years, a rechargeable aluminum-ion battery based on ionic liquid electrolyte is being extensively explored due to three-electron electrochemical reactions, rich resources, and safety. Herein, a rechargeable Al-ion battery composed of MoS2 microsphere cathode, aluminum anode, and ionic liquid electrolyte has been fabricated for the first time. It can be found that Al3+ intercalates into the MoS2 during the electrochemical reaction, whereas the storage mechanisms of the electrode material interface and internal are quite different. This result is confirmed by ex situ X-ray photoelectron spectroscopy and X-ray diffraction etching techniques. Meanwhile, this aluminum-ion battery also shows excellent electrochemical performance, such as a discharge specific capacity of 253.6 mA h g-1 at a current density of 20 mA g-1 and a discharge capacity of 66.7 mA h g-1 at a current density of 40 mA g-1 after 100 cycles. This will lay a solid foundation for the commercialization of aluminum-ion batteries.

AB - Low sulfur utilization and poor cycle life of the sulfur cathode with high sulfur loadings remain a great challenge for lithium-sulfur (Li-S) battery. Herein, the free-standing carbon film consisting of porous carbon nanofibers (PCNFs) and carbon nanotubes (CNTs) is successfully fabricated by the electrospinning technology. The PCNF/CNT film with three-dimensional and interconnected structure is promising for the uniformity of the high-loading sulfur, good penetration of the electrolyte, and reliable accommodation of volumetric expansion of the sulfur cathode. In addition, the abundant N/O-doped elements in PCNF/CNT film are helpful to chemically trap soluble polysulfides in the charge-discharge processes. Consequently, the obtained monolayer S/PCNF/CNT film as the cathode shows high specific capacity, excellent cycle stability, and rate stability with the sulfur loading of 3.9 mg cm-2. Moreover, the high areal capacity of 13.5 mA h cm-2 is obtained for the cathode by stacking three S/PCNF/CNT layers with the high sulfur loading of 12 mg cm-2. The stacking-layered cathode with high sulfur loading provides excellent cycle stability, which is beneficial to fabricate high energy-density Li-S battery in future. PMID- 29469562 TI - Surface Topography Hinders Bacterial Surface Motility. AB - We demonstrate that the surface motility of the bacterium, Pseudomonas aeruginosa, is hindered by a crystalline hemispherical topography with wavelength in the range of 2-8 MUm. The motility was determined by the analysis of time lapse microscopy images of cells in a flowing growth medium maintained at 37 degrees C. The net displacement of bacteria over 5 min is much lower on surfaces containing 2-8 MUm hemispheres than on flat topography, but displacement on the 1 MUm hemispheres is not lower. That is, there is a threshold between 1 and 2 MUm for response to the topography. Cells on the 4 MUm hemispheres were more likely to travel parallel to the local crystal axis than in other directions. Cells on the 8 MUm topography were less likely to travel across the crowns of the hemispheres and were also more likely to make 30 degrees -50 degrees turns than on flat surfaces. These results show that surface topography can act as a significant barrier to surface motility and may therefore hinder surface exploration by bacteria. Because surface exploration can be a part of the process whereby bacteria form colonies and seek nutrients, these results help to elucidate the mechanism by which surface topography hinders biofilm formation.

AB - Structural colors arising from all-dielectric nanostructures are very promising for high-resolution color nanoprinting and high-density optical storage. However, once the all-dielectric nanostructures are fabricated, their optical performances are usually static or change slowly, significantly limiting the practical applications in advanced displays. Herein, we experimentally demonstrate the real time tunable colors with microfluidic reconfigurable all-dielectric metasurfaces. The metasurface is composed of an array of TiO2 nanoblocks, which are embedded in a polymeric microfluidic channel. By injecting solutions with a different refractive index into the channel, the narrow band reflection peak and the corresponding distinct colors of a TiO2 metasurface can be precisely controlled. The transition time is as small as 16 ms, which is orders of magnitude faster than the current techniques. By varying the lattice size of TiO2 metasurfaces, the real-time tunable colors are able to span the entire visible spectrum. Meanwhile, the injection and ejection of solvent have also shown the capability of the erasion and the restoration of information encoded in TiO2 metasurfaces. The combination of all-dielectric nanostructures with microfluidic channels shall boost their applications in functional color display, banknote security, anticounterfeiting, and point-of-care devices. PMID- 29469564 TI - MXene as a Charge Storage Host. AB - The development of efficient electrochemical energy storage (EES) devices is an important sustainability issue to realize green electrical grids. Charge storage mechanisms in present EES devices, such as ion (de)intercalation in lithium-ion batteries and electric double layer formation in capacitors, provide insufficient efficiency and performance for grid use. Intercalation pseudocapacitance (or redox capacitance) has emerged as an alternative chemistry for advanced EES devices. Intercalation pseudocapacitance occurs through bulk redox reactions with ultrafast ion diffusion. In particular, the metal carbide/nitride nanosheets termed MXene discovered in 2011 are a promising class of intercalation pseudocapacitor electrode materials because of their compositional versatility for materials exploration (e.g., Ti2CT x, Ti3C2T x, V2CT x, and Nb2CT x, where T is a surface termination group such as F, Cl, O, or OH), high electrical conductivity for high current charge, and a layered structure of stacked nanosheets for ultrafast ion intercalation. Various MXene electrodes have been reported to exhibit complementary battery performance, such as large specific capacity at high charge/discharge rates. However, general design strategies of MXenes for EES applications have not been established because of the limited understanding of the electrochemical mechanisms of MXenes. This Account describes current knowledge of the fundamental electrochemical properties of MXenes and attempts to clarify where intercalation capacitance ends and intercalation pseudocapacitance begins. MXene electrodes in aqueous electrolytes exhibit intercalation of hydrated cations. The hydrated cations form an electric double layer in the interlayer space to give a conventional capacitance within the narrow potential window of aqueous electrolytes. When nonaqueous electrolytes are used, although solvated cations are intercalated into the interlayer space during the initial stage of charging, the confined solvation shell should gradually collapse because of the large inner potential difference in the interlayer space. Upon further charging, desolvated ions solely intercalate, and the atomic orbitals of the desolvated cations overlap with the orbitals of MXene to form a donor band. The formation of the donor band induces the reduction of MXene, giving rise to an intercalation pseudocapacitance through charge transfer from the ions to MXene sheets. Differences in the electrochemical reaction mechanisms lead to variation of the electrochemical responses of MXenes (e.g., cyclic voltammetry curves, specific capacitance), highlighting the importance of establishing a comprehensive grasp of the electrochemical reactions of MXenes at an atomic level. Because of their better charge storage kinetics compared with those of typical materials used in present EES devices, aqueous/nonaqueous asymmetric capacitors using titanium carbide MXene electrodes are capable of efficient operation at high charge/discharge rates. Therefore, the further development of novel MXene electrodes for advanced EES applications is warranted. PMID- 29469565 TI - Reduced Graphene Oxide-Incorporated SnSb@CNF Composites as Anodes for High Performance Sodium-Ion Batteries. AB - Sodium-ion batteries (SIBs) are promising alternatives to lithium-ion batteries because of the low cost and natural abundance of sodium resources. Nevertheless, low energy density and poor cycling stability of current SIBs unfavorably hinder their practical implementation for the smart power grid and stationary storage applications. Antimony tin (SnSb) is one of the most promising anode materials for next-generation SIBs attributing to its high capacity, high abundance, and low toxicity. However, the practical application of SnSb anodes in SIBs is currently restricted because of their large volume changes during cycling, which result in serious pulverization and loss of electrical contact between the active material and the carbon conductor. Herein, we apply reduced graphene oxide (rGO) incorporated SnSb@carbon nanofiber (SnSb@rGO@CNF) composite anodes in SIBs that can sustain their structural stability during prolonged charge-discharge cycles. Electrochemical performance results shed light on that the combination of rGO, CNF, and SnSb alloy led to a high-capacity anode (capacity of 490 mAh g-1 at the 10th cycle) with a high capacity retention of 87.2% and a large Coulombic efficiency of 97.9% at the 200th cycle. This work demonstrates that the SnSb@rGO@CNF composite is a potential and attractive anode material for next generation, high-energy SIBs. PMID- 29469566 TI - Commercially Available Activated Carbon Fiber Felt Enables Efficient Solar Steam Generation. AB - Sun-driven steam generation is now possible and has the potential to help meet future energy needs. Current technologies often use solar condensers to increase solar irradiance. More recently, a technology for solar steam generation that uses heated surface water and low optical concentration is reported. In this work, a commercially available activated carbon fiber felt is used to generate steam efficiently under one sun illumination. The evaporation rate and solar conversion efficiency reach 1.22 kg m-2 h-1 and 79.4%, respectively. The local temperature of the evaporator with a floating activated carbon fiber felt reaches 48 degrees C. Apart from the high absorptivity (about 94%) of the material, the evaporation performance is enhanced thanks to the well-developed pores for improved water supply and steam escape and the low thermal conductivity, which enables reduced bulk water temperature increase. This study helps to find a promising material for solar steam generation using a water evaporator that can be produced economically (~6 $/m2) with long-term stability. PMID- 29469567 TI - Compact-Nanobox Engineering of Transition Metal Oxides with Enhanced Initial Coulombic Efficiency for Lithium-Ion Battery Anodes. AB - A novel strategy is proposed to construct a compact-nanobox (CNB) structure composed of irregular nanograins (average diameter ~ 10 nm), aiming to confine the electrode-electrolyte contact area and enhance initial Coulombic efficiency (ICE) of transition metal oxide (TMO) anodes. To demonstrate the validity of this attempt, CoO-CNB is taken as an example which is synthesized via a carbothermic reduction method. Benefiting from the compact configuration, electrolyte can only contact the outer surface of the nanobox, keeping the inner CoO nanograins untouched. Therefore, the solid electrolyte interphase (SEI) formation is reduced. Furthermore, the internal cavity leaves enough room for volume variation upon lithiation and delithiation, resulting in superior mechanical stability of the CNB structure and less generation of fresh SEI. Consequently, the SEI remains stable and spatially confined without degradation, and hence, the CoO-CNB electrode delivers an enhanced ICE of 82.2%, which is among the highest values reported for TMO-based anodes in lithium-ion batteries. In addition, the CoO-CNB electrode also demonstrates excellent cyclability with a reversible capacity of 811.6 mA h g-1 (90.4% capacity retention after 100 cycles). These findings open up a new way to design high-ICE electrodes and boost the practical application of TMO anodes. PMID- 29469568 TI - Venturing beyond Donor-Controlled Glycosylation: New Perspectives toward Anomeric Selectivity. AB - Glycans are complex compounds consisting of sugars linked glycosidically, existing either as pure polysaccharides or as part of glycoconjugates. They are prevalent in nature and possess important functions in regulating biological pathways. However, their diversity coupled with physiochemical similarities makes it challenging to isolate them in large quantities for biochemical studies, hence hampering progress in glycobiology and glycomedicine. Glycochemistry presents an alternative strategy to obtain pure glycan compounds through artificial synthetic methods. Efforts in glycochemistry have been centered on glycosylation, the key reaction in glycochemistry, especially with regards to anomeric stereoselectivity in polysaccharides and glycoconjugates. In particular, the stereoelectronic and steric properties of glycosyl donors are commonly used to direct the stereoselectivity in glycosylation reactions. Classic glycosylation strategies typically involve saturated glycosyl donors, proceeding either directly using hydrogen bonds and conformational constraints or indirectly by installing moieties covalently through neighboring group participation and intramolecular aglycon delivery. Over the past years, new glycosylation strategies, tapping on the foundations of transition metal catalysis, have emerged. To leverage the power of coordination chemistry, unsaturated glycosyl donors were introduced. Not only are the number of protection/deprotection steps reduced, the resultant unsaturated glycoside provides opportunities for downstream functionalizations, allowing quick access to a variety of sugars, including rare sugars. Alongside the glycosyl donor, an equally important but neglected aspect for targeting stereoselective glycosylation is the glycosyl acceptor. In the case of dual directing donors, glycosyl acceptors have proved themselves capable of becoming the dominating factor for stereocontrol. Interestingly, rational manipulation or selection of glycosyl acceptors with particular nucleophilicity and p Ka values can lead to different stereoselectivities, thereby proving the tunability of such acceptors to favor the formation of one anomer over the other stereoselectively. By further venturing beyond substrate controlled stereoselectivity, we are presented with the opportunity to effect stereoselective glycosylation through glycosylating reagents. Of the key reagents, stereoselective catalyst stands out as a greener and efficient alternative to direct stereoselective control with stoichiometric substrates. Recently, investigations into this approach of stereocontrol presented an intriguing range of stereoselectivities, achieved by merely varying the nature of catalysts used. Another crucial effort in glycochemistry is enhancing the efficiencies of glycosylations, by reducing the number of preparative steps before or during glycosylation. Through using transient masking groups or one-pot synthetic strategies, these streamlined approaches provide enormous convenience and practicability for oligosaccharide syntheses. This Account presents mainly our advancements beyond the conventional donor-controlled strategies over the past decade, with emphasis placed on mechanistic explanations of anomeric selectivities, thereby providing perspectives to inspire further progress toward a generalized unified strategy for preparing every type of glycan. PMID- 29469569 TI - Role of Metal Electronegativity in the Dehydrogenation Thermodynamics and Kinetics of Composite Metal Borohydride-LiNH2 Hydrogen Storage Materials. AB - The composites of M(BH4) n-LiNH2 (1/2 n molar ratio, n = 1 or 2, M = Ca, Mg, Li) were synthesized by liquid ball milling. Samples were characterized by X-ray diffraction, thermogravimetry-differential thermal analysis-mass spectroscopy (TG DTA-MS), and kinetic models (Achar differential/Coats-Redfern integral method). The higher-electronegativity metal M in M(BH4) n-4LiNH2 (M = Ca, Mg) samples not only enables [BH4]- group to release easily, so as to facilitate the interaction of [BH4]- and [NH2]- groups, but also restrains the NH3 release and slightly decreases the onset dehydrogenation temperature concluded by TG-MS. Moreover, in stage 1 (200-350 degrees C), the kinetics performances of M(BH4) n-4LiNH2 (M = Ca, Mg) samples are distinctly improved, that is, the activation energies of them are reduced by ca. 30% compared to those of sample LiBH4-2LiNH2. The outstanding contribution of the replacement of M(BH4) n with high-electronegativity metal ion is to both improve the kinetics performance by changing the kinetics mechanism and decrease the temperature range of the initial dehydrogenation region.

AB - Two new acylated beta-hydroxynitrile glycosides, ribemansides A (1) and B (2), were isolated from the aerial parts of Ribes manshuricum. Their structures were elucidated by comprehensive spectroscopic analysis. Ribemansides A and B inhibited transforming growth factor beta1 (TGF-beta1)-induced expression of alpha-smooth muscle actin, fibronectin release, and changes in cell morphology in the human proximal tubular epithelial cell line (human kidney-2, HK-2). Further biological evaluation demonstrated that both 1 and 2 inhibit the activity of canonical transient receptor potential cation channel 6 (TRPC6), with IC50 values of 24.5 and 25.6 MUM, respectively. The antifibrogenic effect of these compounds appears to be mediated through TRPC6 inhibition, since the TRPC6 inhibitor, SAR7334, also suppressed TGF-beta1-induced fibrogenesis in HK-2 cells. PMID- 29469571 TI - Single-Step In Situ Acetylcholinesterase-Mediated Alginate Hydrogelation for Enzyme Encapsulation in CE. AB - A novel capillary electrophoresis-integrated immobilized enzyme reactor (CE integrated IMER) is developed using single-step in situ acetylcholinesterase (AChE)-mediated alginate hydrogelation and enzyme encapsulation. Alginate hydrogelation with "egg-box" structure is triggered inside a capillary with releasing of Ca2+ by changing the pH of the sol solution, which is accomplished in situ by AChE-catalyzed hydrolysis reaction of acetylthiocholine to produce acetic acid. AChE and any other enzyme initially contained in the sol solution [e.g., xanthine oxidase (XO)] are efficiently encapsulated as the hydrogel network grows, forming CE-integrated IMERs without any additional manipulation process. The proposed method facilitates the analysis of different kinds of enzymes using the same IMER depending on the substrate injected for CE analysis. Approximately 68% of the original enzyme in the sol mixture can be encapsulated, indicating high loading capacity for the CE-integrated IMERs. The IMERs exhibit excellent intraday and interday stability and batch-to-batch reproducibility, and these characteristics imply the reliability of the proposed IMERs for accurate online enzyme assays. Enzymatic activities and inhibition of immobilized AChE and XO are analyzed, and the results are compared with those using free enzymes. The feasibility of the proposed method for potential application in real sample analysis is demonstrated by the successful application of the IMERs in detecting organophosphorus pesticides in apple juice samples using AChE-catalyzed reactions. The proposed method is a simple, efficient, and universal approach for online CE assays with immobilized enzymes, which can be widely applied in bioanalysis. PMID- 29469572 TI - Multiple Pathways in the Self-Assembly Process of a Pd4L8 Coordination Tetrahedron. AB - The self-assembly of a Pd418 coordination tetrahedron (Tet) from a ditopic ligand, 1, and palladium(II) ions, [PdPy*4]2+ (Py* = 3-chloropyridine), was investigated by a 1H NMR-based quantitative approach (quantitative analysis of self-assembly process, QASAP), which allows one to monitor the average composition of the intermediates not observed by NMR spectroscopy. The self assembly of Tet takes place mainly through three pathways and about half of the Tet structures were produced through the reaction of a kinetically produced Pd3L6 double-walled triangle (DWT) and 200-nm-sized large intermediates (IntL). In two of the three pathways, the leaving ligand (Py*), which is not a component of Tet, catalytically assisted the self-assembly. Such a multiplicity of the self assembly process of Tet suggests that molecular self-assembly takes place on an energy landscape like a protein-folding funnel. PMID- 29469574 TI - Control of Excitation Energy Transfer in Condensed Phase Molecular Systems by Floquet Engineering. AB - Excitation energy transfer (EET) is one of the most important processes in both natural and artificial chemical systems including, for example, photosynthetic complexes and organic solar cells. The EET rate, however, is strongly suppressed when there is a large difference in the excitation energy between the donor and acceptor molecules. Here, we demonstrate both analytically and numerically that the EET rate can be greatly enhanced by periodically modulating the excitation energy difference. The enhancement of EET by using this Floquet engineering, in which the system's Hamiltonian is made periodically time-dependent, turns out to be efficient even in the presence of strong fluctuations and dissipations induced by the coupling with a huge number of dynamic degrees of freedom in the surrounding molecular environments. As an effect of the environment on the Floquet engineering of EET, the optimal driving frequency is found to depend on the relative magnitudes of the system and environment's characteristic time scales with an observed frequency shift when moving from the limit of slow environmental fluctuations (inhomogeneous broadening limit) to that of fast fluctuations (homogeneous broadening limit). PMID- 29469573 TI - Nonconjugated Acyloxy Group Deactivates the Intramolecular Charge-Transfer State in the Carotenoid Fucoxanthin. AB - We used ultrafast transient absorption spectroscopy to study excited-state dynamics of the keto-carotenoid fucoxanthin (Fx) and its two derivatives: 19' butanoyloxyfucoxanthin (bFx) and 19'-hexanoyloxyfucoxanthin (hFx). These derivatives occur in some light-harvesting systems of photosynthetic microorganisms, and their presence is typically related to stress conditions. Even though the hexanoyl (butanoyl) moiety is not a part of the conjugated system of hFx (bFx), their absorption spectra in polar solvents exhibit more pronounced vibrational bands of the S2 state than for Fx. The effect of the nonconjugated acyloxy moiety is further observed in transient absorption spectra, which for Fx exhibit characteristic features of an intramolecular charge transfer (ICT) state in all polar solvents. For bFx and hFx, however, much weaker ICT features are detected in methanol, and the spectral markers of the ICT state disappear completely in polar, but aprotic acetonitrile. The presence of the acyloxy moiety also alters the lifetimes of the S1/ICT state. For Fx, the lifetimes are 60, 30, and 20 ps in n-hexane, acetonitrile, and methanol, whereas for bFx and hFx, these lifetimes yield 60, 60, and 40 ps, respectively. Testing the S1/ICT state lifetimes of hFx in other solvents revealed that some ICT features can be induced only in polar, protic solvents (methanol, ethanol, and ethylene glycol). Thus, bFx and hFx represent a rather rare example of a system in which a nonconjugated functional group significantly alters excited-state dynamics. By comparison with other carotenoids, we show that a keto group at the acyloxy tail, even though it is not in conjugation, affects the electron distribution along the conjugated backbone, resulting in the observed decrease of the ICT character of the S1/ICT state of bFx and hFx.

AB - A high-content imaging assay was used to screen the fraction collection of the Natural Product Library at The Scripps Research Institute for inhibitors of Cryptosporidium parvum. A chemical investigation of one strain, Streptomyces sp. CB01388, resulted in the isolation of six herbicidins (1-6), one of which is new (herbicidin L, 1). Five of the six herbicidins (1-3, 5, 6) showed moderate inhibitory activity against C. parvum, with 1 and 6 comparable to the FDA approved drug nitazoxanide, and 2-6 showed no toxicity to the host HCT-8 cells and human HEK293T and HepG2 cells. These findings highlight the herbicidin scaffold for anti- Cryptosporidium drug development. PMID- 29469576 TI - Structure and Relaxation in Solutions of Monoclonal Antibodies. AB - Reversible self-association of therapeutic antibodies is a key factor in high protein solution viscosities. In the present work, a coarse-grained computational model accounting for electrostatic, dispersion, and long-ranged hydrodynamic interactions of two model monoclonal antibodies is applied to understand the nature of self-association, predicting the solution microstructure and resulting transport properties of the solution. For the proteins investigated, the structure factor across a range of solution conditions shows quantitative agreement with neutron-scattering experiments. We observe a homogeneous, dynamical association of the antibodies with no evidence of phase separation. Calculations of self-diffusivity and viscosity from coarse-grained dynamic simulations show the appropriate trends with concentration but, respectively, over- and under-predict the experimentally measured values. By adding constraints to the self-associated clusters that rigidify them under flow, prediction of the transport properties is significantly improved with respect to experimental measurements. We hypothesize that these rigidity constraints are associated with missing degrees of freedom in the coarse-grained model resulting from patchy and heterogeneous interactions among coarse-grained domains. These results demonstrate how structural anisotropy and anisotropy of interactions generated by features at the 2-5 nm length scale in antibodies are sufficient to recover the dynamics and rheological properties of these important macromolecular solutions.

A wide range of heterobicyclic alkenes, including azabenzonorbornadienes and oxabenzonorbornadienes, were well tolerated in the reaction with various anilines, and they generally delivered the corresponding chiral aryltetralin derivatives in good to excellent enantioselectivities.

This operationally simple reaction relies on readily available starting materials and leads to useful products in diastereoselectivities of up to 7:1. The versatility of this new method is demonstrated through the stereoselective one-step synthesis of an AChE inhibitor. PMID- 29469579 TI - Big data in psychology: A framework for research advancement. AB - The potential for big data to provide value for psychology is significant. However, the pursuit of big data remains an uncertain and risky undertaking for the average psychological researcher. In this article, we address some of this uncertainty by discussing the potential impact of big data on the type of data available for psychological research, addressing the benefits and most significant challenges that emerge from these data, and organizing a variety of research opportunities for psychology. Our article yields two central insights. First, we highlight that big data research efforts are more readily accessible than many researchers realize, particularly with the emergence of open-source research tools, digital platforms, and instrumentation. Second, we argue that opportunities for big data research are diverse and differ both in their fit for varying research goals, as well as in the challenges they bring about. Ultimately, our outlook for researchers in psychology using and benefiting from big data is cautiously optimistic. Although not all big data efforts are suited for all researchers or all areas within psychology, big data research prospects are diverse, expanding, and promising for psychology and related disciplines.

PMID- 29469580 TI - The psychometric properties of the Personality Assessment Inventory-Adolescent's Borderline Features Scale across two high-risk samples. AB - The present study sought to assess the performance of the Borderline Features (BOR) Scale of the adolescent version of the Personality Assessment Inventory (Morey, 2007b) in 2 high-risk samples: inpatient and justice-involved adolescents. This study is the first to evaluate the BOR scale in high-risk adolescent samples, outside the initial standardization studies. Across both samples (NClinical = 327, NForensic = 151), results indicated good internal consistency. Confirmatory factor analysis indicated poor fit of the 4-factor structure proposed by the measure's authors. Convergent validity and receiver operating characteristics analyses, conducted in the clinical sample, indicated that the adolescent version of the Personality Assessment Inventory BOR scale had good diagnostic accuracy for predicting a borderline personality disorder diagnosis (via structured interview). Findings suggest that the BOR scale has adequate internal consistency, convergent validity, and clinical utility, although areas for future measure evaluation (including factor structure) remain. Still, the BOR scale may partially address the current hesitation to assess borderline personality disorder features in high-risk youth because it is embedded within a broadband psychopathology measure. (PsycINFO Database Record PMID- 29469581 TI - A comprehensive examination of the psychometric properties of the Hare Psychopathy Checklist-Revised in a Canadian multisite sample of indigenous and non-indigenous offenders. AB - The present study examined the psychometric properties of Hare Psychopathy Checklist-Revised (PCL-R; Hare, 2003) scores in a multisite sample of 1,163 federally incarcerated Canadian indigenous and non-indigenous offenders from the Prairie Region of the Correctional Service of Canada. The research occurred against the backdrop of the Ewert v. Canada (2015) matter, in which the PCL-R was originally impugned in Federal Court for use with indigenous persons (later overturned in Canada v. Ewert, 2016). Indigenous men scored higher than non indigenous men on most components of the PCL-R and had higher rates of recidivism, irrespective of follow-up. Discrimination analyses, however, supported the predictive efficacy of PCL-R total, factor, and facet scores for violent and general recidivism across both ancestral groups, with most group differences in area under the curve (AUC) magnitudes being small and nonsignificant. Calibration analyses demonstrated that higher PCL-R scores were associated with higher rates of general and violent recidivism for both ancestral groups, although higher recidivism rates were observed and estimated for indigenous men at specific PCL-R score thresholds. Confirmatory factor analyses supported the 4-factor model of psychopathy and hence, structural invariance, of PCL-R scores across ancestral groups. Structural equation modeling affirmed the predictive efficacy of the 4-factor model for recidivism. We discuss these findings in terms of clinical applications of the PCL-R and the psychopathy construct in general, with male offenders of indigenous ancestry. (PsycINFO Database Record PMID- 29469582 TI - Contrasting hemispheric asymmetries for emotional processing from event-related potentials and behavioral responses. AB - OBJECTIVE: Four main theories concerning hemispheric asymmetries for emotional processing have been proposed: the right hemisphere hypothesis (RHH; the right hemisphere is specialized in processing all emotions), the valence hypothesis (VH; the left and the right hemispheres are superior in positive and negative emotion processing, respectively), the modified VH (the right-hemispheric superiority at posterior sites is followed by a valence-specific activity at frontal sites), and the motivational model (the left and the right hemispheres are superior in approaching-related and avoidance-related emotions, respectively). METHOD: In a divided visual field paradigm, we presented happy and angry faces to 16 healthy participants, either unilaterally or bilaterally, in order to test the aforementioned theories. RESULTS: Behavioral results provided support for the VH and correlational analysis revealed that handedness influences the rightward bias for positive emotions. The amplitude of P1, N170, and P2 event related potential components at parietal sites (selected by means of topographic maps) was larger in the right than in the left hemisphere, independently of the emotional expression of the stimuli, supporting the RHH. At frontal sites, no asymmetry was found in bilateral conditions, whereas in unilateral conditions, a mixed pattern of hemispheric asymmetries emerged. CONCLUSIONS: We conclude that there is no correspondence between behavioral and electrophysiological results concerning asymmetries for emotion processing, and that the VH and the RHH are not mutually exclusive. (PsycINFO Database Record PMID- 29469583 TI - Cognitive flexibility and dual processing in pigeons: Temporal and contextual control of midsession reversal. AB - Evidence is reported showing that pigeons flexibly use temporal and contextual cues to maximize reward obtained in a midsession reversal task. Pigeons were trained to choose between red and green sidekeys for 60 trials in a session, with choice of one color correct on Trials 1-30 and choice of the other color correct on Trials 31-60 (midsession reversal). Pigeons showed anticipatory errors before reversal and perseverative errors after reversal, and manipulations of the length of the intertrial interval and the point of reversal suggested that pigeons used an internal timer to track the point of reversal. When houselight context cues that signaled the correct choice were presented throughout trials in Experiment 1, choice behavior rapidly came under context control, leading pigeons to rarely make errors and to show no effect of intertrial interval or point of reversal. In Experiments 2 and 3, switches between context and no-context cues occurred among trials. These manipulations revealed that pigeons can readily switch between context control and temporal control of behavior. The internal timer continued to run throughout context trials and could readily be accessed to control choice behavior when a context cue was removed. (PsycINFO Database Record PMID- 29469584 TI - Paid sick leave status in relation to government sponsored welfare utilization. AB - Nearly a third of all U.S. workers, primarily lower-paid employees, do not have paid sick leave benefits, prompting some lawmakers to consider mandating paid sick leave for all U.S. employees so workers can access timely health care without lost wages. A representative sample of 19,537 workers in current paid employment was examined, searching for the association between access to paid sick leave benefits and receipt of six different welfare and welfare-related services. After controlling for relevant demographic, work, income, and medical/health care variables, results of the logistic models indicate that, among working adults age 18-64, those without paid sick leave are 1.41 times more likely to receive income from a state or county welfare program, 1.36 times more likely to receive other welfare assistance (transportation and child care supports), 1.33 times more likely to received sponsored rental assistance, and 1.34 times more likely to receive Supplemental Nutrition Assistance Program benefits (referred to as food stamps commonly and in this article). Mandating paid sick leave benefits may impact usage of social welfare assistance since families with paid sick leave do not have to lose wages when work is missed because of health and caregiver responsibilities. (PsycINFO Database Record PMID- 29469585 TI - Proactive aggression in early school-aged children with externalizing behavior problems: A longitudinal study on the influence of empathy in response to distress. AB - The course of proactive aggressive behavior may be affected by empathy in response to sadness and distress of others. The aim of the current study is to examine empathy in response to sadness and distress and its relation to proactive and reactive aggression in a clinical sample of children with externalizing behavior problems. At baseline (T1) and 12 months later (T2), parents and teachers of 104 six- and seven-year-old children completed the Instrument for Reactive and Proactive Aggression. At T1, parents and teachers also reported empathy in response to sadness and distress on the Griffith Empathy Measure. Findings show that low levels of parent-reported empathy at baseline were specifically associated with high parent-reported proactive aggression but not with reactive aggression. Similarly, low teacher-reported empathy was specifically related to high teacher-reported proactive aggression. Furthermore, high parent-reported but not teacher-reported empathy at baseline was associated with low proactive aggression at 12 months after controlling for proactive aggression at baseline. The conclusions support the notion that in the study of the course of aggression in clinical groups, the distinction between proactive and reactive aggression as well as the study of empathy in response to distress is relevant for a better understanding and might be taken into account in the development of future interventions. (PsycINFO Database Record PMID- 29469586 TI - Fixation reinstatement supports visuospatial memory in older adults. AB - Research using eye movement monitoring suggests that recapitulating the pattern of eye movements made during stimulus encoding at subsequent retrieval supports memory by reinstating the spatial layout of the encoded stimulus. In the present study, the authors investigated whether recapitulation of encoding fixations during a poststudy, stimulus-free delay period-an effect that has been previously linked to memory maintenance in younger adults-can support mnemonic performance in older adults. Older adults showed greater delay-period fixation reinstatement than younger adults, and this reinstatement supported age-equivalent performance on a subsequent visuospatial-memory-based change detection task, whereas in younger adults, the performance-enhancing effects of fixation reinstatement increased with task difficulty. Taken together, these results suggest that fixation reinstatement might reflect a compensatory response to increased cognitive load. The present findings provide novel evidence of compensatory fixation reinstatement in older adults and demonstrate the utility of eye movement monitoring for aging and memory research. (PsycINFO Database Record PMID- 29469587 TI - Simulational fluency reduces feelings of psychological distance. AB - Why do some events feel "like yesterday" whereas others feel "ages away"? Past research has identified cues that influence people's estimates of distance in units such as how many miles or days away events are from the self. However, what makes events feel psychologically close or distant? We examine the hypothesis that increased simulational fluency, the ease with which people mentally imagine events, makes events feel psychologically close. Simulational fluency was associated with feelings that multiple past and future holidays were psychologically close (Studies 1a and 1b). Writing short, easy-to-generate descriptions of Christmas made it feel psychologically closer and more fluently simulated compared with writing longer, difficult-to-generate descriptions (Study 2). This pattern was not anticipated by readers of the same content who did not directly experience the fluency of writing descriptions. Writing descriptions of Halloween made it feel fluently simulated and psychologically close, even as concrete "how" descriptions reduced construal level compared with abstract "why" descriptions (Study 3). Listening to a fluent audio description of a past Super Bowl, compared with a disfluent audio description, caused the game to feel psychologically closer in both space and time (Study 4). Reading a description of the Super Bowl in easy-to-read font, compared with difficult-to-read font, made the game feel more fluently simulated and psychologically closer (Study 5). These findings have implications for theories of psychological distance and its role in everyday life. (PsycINFO Database Record PMID- 29469588 TI - Robust, replicable, and theoretically-grounded: A response to Brown and Coyne's (2017) commentary on the relationship between emodiversity and health. AB - In 2014 in the Journal of Experimental Psychology: General, we reported 2 studies demonstrating that the diversity of emotions that people experience-as measured by the Shannon-Wiener entropy index-was an independent predictor of mental and physical health, over and above the effect of mean levels of emotion. Brown and Coyne (2017) questioned both our use of Shannon's entropy and our analytic approach. We thank Brown and Coyne for their interest in our research; however, both their theoretical and empirical critiques do not undermine the central theoretical tenets and empirical findings of our research. We present an in-depth examination that reveals that our findings are statistically robust, replicable, and reflect a theoretically grounded phenomenon with real-world implications. (PsycINFO Database Record PMID- 29469589 TI - Preparation of Vitamin E-Containing High-Density Lipoprotein and Its Protective Efficacy on Macrophages. AB - Atherosclerosis is a major cause for cardiovascular diseases. High-density lipoprotein (HDL) may reduce atherosclerosis through several different mechanisms. HDL is composed of lipids, cholesterol, cholesteryl esters, triglycerides, and phospholipids, mainly phosphatidylcholine plus specialized proteins called apolipoproteins (apos). In this study, we prepared vitamin E containing HDL (VE-HDL) that contains egg phosphatidylcholine, cholesterol, vitamin E, and two kinds of recombinant human apolipoproteins (rhapo)-rhapoA-I and rhapoE in vitro by the facilitation of cholate. After that, we studied the effects of VE-HDL on foam cell formation, cellular cholesterol efflux, oxidative low-density lipoprotein (oxLDL)-stimulated oxidative stress, and apoptosis of macrophages to evaluate the protective efficacy of VE-HDL on macrophages. As the results showed, we prepared a new type of reconstituent HDL with apolipoproteins and vitamin E for the first time. VE-HDL has protective efficacy on macrophages. It has the prospect of becoming a therapeutic agent on atherosclerosis in the future. PMID- 29469590 TI - Association of physical functioning of persons with dementia with caregiver burden and depression in dementia caregivers: an integrative data analysis. AB - OBJECTIVES: To determine whether caregiver relationship and race modify associations between physical functioning of persons with dementia (PWD) and their caregiver's burden and general depressive symptoms. METHOD: We pooled data from four behavioral intervention trials (N = 1,211). Using latent growth modeling, we evaluated associations of PWD physical functioning with the level and rate of change in caregiver burden and caregivers' general depressive symptoms and stratified these associations by caregiver relationship and race. RESULTS: PWD were, on average, 81 years old (68% female) with mean follow-up of 0.5 years. More baseline PWD physical impairment was associated with less worsening in caregiver burden over time (beta = -0.23, 95% CI: -0.29, -0.14), but this relationship was not modified by caregiver characteristics. More impaired baseline PWD physical functioning was not associated with changes in depressive symptoms (beta = -0.08, 95% CI: -0.17, 0.00), but was associated with less worsening in depressive symptoms among spousal (beta = -0.08, 95% CI: -0.17, 0.00) and non-white (beta = -0.08, 95% CI: -0.17, 0.00) caregivers. CONCLUSIONS: Dementia caregivers may experience reduced caregiver-related burden because of adjustment to PWD functional status, while spousal and non-white caregivers may experience less depressive symptoms resultant of adjustment to functional status. PMID- 29469591 TI - Associations of health insurance coverage, mental health problems, and drug use with mental health service use in US adults: an analysis of 2013 National Survey on Drug Use and Health. AB - OBJECTIVE: To estimate the prevalence of mental health service use among US adults, examine the associations of mental health service use with health insurance coverage, mental health problems and drug use, and detect health disparities. METHODS: This was a cross-sectional study with 5,434 adults receiving mental health service out of 37,424 adult respondents from the 2013 National Survey on Drug Use and Health. Weighted univariate and multiple logistic regression analyses were used to estimate the associations of potential factors with mental health service use. RESULTS: The overall prevalence of mental health services use was 14.7%. Our results showed that being female, aging, having a major depressive episode, serious psychological distress, and illicit drug or alcohol abuse/dependence were positively associated with mental health service use; whereas being African American, Asian or Hispanic ethnicity, married, and having any form of insurance were negatively associated with mental health service use . Stratified analysis by insurance types showed that Medicaid/CHIP, CHAMPUS, and other insurance were positively associated with mental health service use. CONCLUSIONS: Health insurance coverage, mental health problems, and drug abuse or dependence were associated with mental health service use in US adults. Furthermore, adults with different insurances had disparities in access of mental health service. PMID- 29469592 TI - Ixazomib in the management of relapsed multiple myeloma. AB - The development of proteasome inhibitors contributed to the dramatic life expectancy improvement observed in myeloma patients over the past decades. Ixazomib is a boron-containing selective and reversible proteasome inhibitor that demonstrated antimyeloma activity with excellent safety profile. Ixazomib is the first orally available proteasome inhibitor approved in combination with lenalidomide and dexamethasone for the treatment of myeloma patients who received at least one prior therapy. The present review addresses the current knowledge regarding the clinical use of ixazomib in relapsed myeloma patients. PMID- 29469593 TI - l-Carnosine as Adjunctive Therapy in Children and Adolescents with Attention Deficit/Hyperactivity Disorder: A Randomized, Double-Blind, Placebo-Controlled Clinical Trial. AB - OBJECTIVES: This study aimed to investigate the efficacy and tolerability of l carnosine as an add-on to methylphenidate in management of children with attention-deficit/hyperactivity disorder (ADHD). METHODS: This was an 8-week, randomized, double-blind placebo-controlled study. Fifty-six drug-free children and adolescents aged 6-17 years old with a diagnosis of ADHD entered the study. The patients were randomly assigned to l-carnosine (800 mg/d in two divided doses) or placebo plus methylphenidate (0.5-1.5 mg/kg/d) for 8 weeks. Children were assessed using the Teacher and Parent ADHD Rating Scale-IV (ADHD-RS-IV) at baseline and at weeks 4 and 8 postbaseline. RESULTS: Fifty patients completed the study, and all had two postbaseline measurements. Using the general linear model repeated measures, significant effect was observed for time * treatment interaction on total and inattention subscales of the Parent ADHD-RS (Greenhouse Geisser corrected: F = 3.783, df = 1.444, p = 0.041 and F = 4.032, df = 1.600, p = 0.030). Improvements in the Teacher ADHD-RS were not significantly different between the two groups in total (Greenhouse-Geisser corrected: F = 0.200, df = 1.218, p = 0.705), as well as inattention and hyperactivity subscale scores (p = 0.956 and 0.281, respectively). The frequency of side effects was not significantly different between the two treatment arms. CONCLUSIONS: l-carnosine, as a supplementary medication, might be beneficial in treatment of children with ADHD. However, further investigations and different doses of l-carnosine are required to replicate these findings in children with ADHD. PMID- 29469595 TI - Combined treatment for skin laxity of the aging face with monopolar radiofrequency and intense focused ultrasound in Korean subjects. AB - BACKGROUND: Although various minimal invasive approaches are available for aging skin laxity, they alone may not lead to notably satisfactory results. OBJECTIVE: To evaluate the effectiveness and safety of combination regimen with monopolar radiofrequency (MRF) and intense-focused ultrasound (IFUS) in facial lifting and tightening. METHODS: Twenty-two Korean participants with aging face received a sequential single session of MRF and IFUS treatment. Objective and subjective assessments for improvement were performed at the 20-week post-treatment. Safety profiles were also recorded, and skin biopsies were taken at baseline and follow up visit. RESULTS: Based on the objective assessment for the overall facial skin tightening and laxity, 19 patients (90%) demonstrated "moderate" or better improvements (more than 25%) compared with baseline. Specifically, improvements of skin laxity and sagging, and droopy jaw line were more noticeable compared with that of superficial skin texture (P < 0.05). Subjective satisfactions were generally consistent with objective findings, and no serious adverse effect was observed. Histologic evaluation showed increased dermal collagen fibers throughout the dermis after treatments (P < 0.05). CONCLUSION: Combination treatment of MRF and IFUS has cumulative benefits for skin lifting and tightening with satisfactory safety profiles in Asian subjects. PMID- 29469594 TI - Positional effects revealed in Illumina methylation array and the impact on analysis. AB - AIM: We aimed to prove the existence of positional effects in the Illumina methylation beadchip data and to find an optimal correction method. MATERIALS & METHODS: Three HumanMethylation450, three HumanMethylation27 datasets and two EPIC datasets were analyzed. ComBat, linear regression, functional normalization and single-sample Noob were used for minimizing positional effects. The corrected results were evaluated by four methods. RESULTS: We detected 52,988 CpG loci significantly associated with sample positions, 112 remained after ComBat correction in the primary dataset. The pre- and postcorrection comparisons indicate the positional effects could alter the measured methylation values and downstream analysis results. CONCLUSION: Positional effects exist in the Illumina methylation array and may bias the analyses. Using ComBat to correct positional effects is recommended. PMID- 29469596 TI - Genome-scale metabolic models as platforms for identification of novel genes as antimicrobial drug targets. AB - The growing number of multidrug-resistant pathogenic bacteria is becoming a world leading challenge for the scientific community and for public health. However, advances in high-throughput technologies and whole-genome sequencing of bacterial pathogens make the construction of bacterial genome-scale metabolic models (GEMs) increasingly realistic. The use of GEMs as an alternative platforms will expedite identification of novel unconditionally essential genes and enzymes of target organisms with existing and forthcoming GEMs. This approach will follow the existing protocol for construction of high-quality GEMs, which could ultimately reduce the time, cost and labor-intensive processes involved in identification of novel antimicrobial drug targets in drug discovery pipelines. We discuss the current impact of existing GEMs of selected multidrug-resistant pathogenic bacteria for identification of novel antimicrobial drug targets and the challenges of closing the gap between genome-scale metabolic modeling and conventional experimental trial-and-error approaches in drug discovery pipelines.

AB - Eccrine hidrocystomes (EH) are benign cystic tumors of dermal eccrine ducts. There is still no gold standard treatment option for EH because of the large number of lesions, the risk of cicatrization and the different treatment options offered. We offer combined oral isotretinoin and following erbium-yttrium aluminum garnet laser treatment as an alternative treatment option in difficult patients with EH. PMID- 29469598 TI - Supporting ethics educators in Canadian occupational therapy and physical therapy programs: A national interprofessional knowledge exchange project. AB - Ethics education is the cornerstone of professional practice, fostering knowledge and respect for core ethical values among healthcare professionals. Ethics is also a subject well-suited for interprofessional education and collaboration. However, there are few initiatives to gather experiences and share resources among ethics educators in rehabilitation. We thus undertook a knowledge exchange project to: 1) share knowledge about ethics training across Canadian occupational and physical therapy programs, and 2) build a community of educators dedicated to improving ethics education. The objectives of this paper are to describe this interprofessional knowledge exchange project involving ethics educators (with a diversity of professional and disciplinary backgrounds) from Canadian occupational and physical therapy programs as well as analyze its outcomes based on participants' experiences/perceptions. Two knowledge exchange strategies were employed: an interactive one-day workshop and a wiki platform. An immediate post workshop questionnaire evaluated the degree to which participants' expectations were met. Structured telephone interviews 9-10 months after the workshop collected participants' perceptions on whether (and if so, how) the project influenced their teaching or led to further interprofessional collaborations. Open-ended questions from the post-workshop questionnaires and individual interviews were analyzed using qualitative methods. Of 40 ethics educators contacted, 23 participated in the workshop and 17 in the follow-up interview. Only 6 participants logged into the wiki from its launch to the end of data collection. Five themes emerged from the qualitative analysis: 1) belonging and networking; 2) sharing and collaborating; 3) changing (or not) ways of teaching ethics; 4) sustaining the network; and 5) envisioning the future of ethics education. The project attained many of its goals, despite encountering some challenges. While the wiki platform proved to be of limited benefit in advancing the project goals, the interactive format and collaborative nature of the one-day workshop were described as rewarding and effective in bringing together occupational therapy and physical therapy educators to meet, network, and share knowledge. PMID- 29469599 TI - Effects of gait training with non-paretic knee immobilization on patients with hemiplegia: Three single-case studies. AB - Patients' with a hemiplegic gait and difficulties with activities of daily living may improve through intensive training of their paretic lower limbs. This study examined the possibility of improving their gait by immobilizing the non-paretic knee joint in extension and promoting weight shift toward the paretic side. Single-case ABABA studies were conducted, involving three patients with hemiplegia. The patients walked with their non-paretic knee joints immobilized in extension using a dial-lock knee orthosis during the intervention (B1 and B2) periods. Measurement items included (1) temporal and distance factors and (2) hip, knee, and ankle joint angles during gait. In all subjects, the stance phase was significantly prolonged on the paretic side during all intervention periods following the first baseline (A1) period. In Subject 1, hip extension in the stance phase improved during all intervention periods following the A1 period, and, in Subjects 2 and 3, the knee hyperextension in the stance phase, which was observed during the A1 period, was resolved during the second (A2) and third (A3) baseline periods. Gait training with non-paretic knee immobilization may promote weight shift toward the paretic side to overcome a swing limitation on the immobilized side, consequently providing an opportunity for training in weight bearing for the paretic limb and an improved, more symmetrical gait pattern. PMID- 29469600 TI - Development and Standardization of Moringa oleifera Leaves as a Natural Dietary Supplement. AB - Moringa oleifera leaves were selected as a model due to their hundreds of health benefits. On the other hand, the powder of these leaves has exhibited poor flowability, low tensile strength, bitter taste, poor dissolution rate, and lack of information regarding dosage. These are the common hurdles and limitations in the adaptation of herbal-based medications. Therefore, a comprehensive study was planned to introduce herbal-based medicines into mainstream medicines by standardization according to the U.S. Food and Drug Administration (FDA) and international pharmaceutical standards. A Simplex Lattice Design (SLD) of Design Expert 8.0 software was used to formulate different concentrations of superdisintegrant, binder/diluent, and sweeteners. An Instron Universal Testing machine coupled with a 13 mm stainless cylindrical die was used to manufacture tablets by means of direct compression method at 20 kN applied force. Therefore, selection of excipients was made on the basis of their tensile strength, flowability, and taste-masking properties. Optimum formulation was tested on rabbits for toxicity and growth rate. All formulated tablets were evaluated on standard parameters for orally disintegrating tablets described by the Food and Drug Authority (U.S.). The optimum formulation fulfills all standard parameters such as hardness, disintegration time, friability, and dissolution rate. The present formulation showed no toxicity when tested on rabbits. The present study provides a fundamental understanding of the tableting characteristics of natural medicines. The present study provides information that will help to overcome the challenges. PMID- 29469601 TI - The Effects of Netarsudil Ophthalmic Solution on Aqueous Humor Dynamics in a Randomized Study in Humans. AB - PURPOSE: Netarsudil, an inhibitor of Rho kinase and a norepinephrine transporter, has been shown to lower elevated intraocular pressure (IOP) in controlled studies of patients with open-angle glaucoma and ocular hypertension, and in healthy volunteers. The mechanism of this ocular hypotensive effect in humans is unknown. METHODS: The objective of this study was to evaluate the effect of netarsudil 0.02% on aqueous humor dynamics (AHD) parameters. In this double-masked, vehicle controlled, paired-eye comparison study, 11 healthy volunteers received topical netarsudil ophthalmic solution 0.02% or its vehicle once daily for 7 days (morning dosing). The primary endpoints were the change in AHD parameters, compared between active and vehicle-treated eyes. RESULTS: In netarsudil-treated eyes, diurnal outflow facility increased from 0.27 +/- 0.10 MUL/min/mmHg to 0.33 +/- 0.11 MUL/min/mmHg (+22%; P = 0.02) after 7 days of treatment. In placebo treated eyes, diurnal outflow facility did not significantly change (P = 0.94). The difference between netarsudil and placebo eyes in diurnal change of outflow facility was 0.08 MUL/min/mmHg (P < 0.001). Diurnal episcleral venous pressure (EVP) in netarsudil-treated eyes decreased from 7.9 +/- 1.2 mmHg to 7.2 +/- 1.8 ( 10%; P = 0.01). Diurnal EVP was not significantly different between netarsudil- and placebo-treated eyes. There was a trend toward decreasing aqueous humor flow rate (-15%; P = 0.08). No treatment changes were seen in uveoscleral outflow rate. CONCLUSIONS: Once-daily dosing of netarsudil ophthalmic solution 0.02% lowered IOP through increasing trabecular outflow facility and reducing EVP. This suggests a combination of mechanisms that affect both the proximal and distal outflow pathways. PMID- 29469602 TI - Can 5 minutes of repetitive prone press-ups and sustained prone press-ups following a period of spinal loading reverse spinal shrinkage? AB - OBJECTIVE: The objective of this study is to investigate if sustained and repetitive prone press-ups could reverse decreased spinal height following spinal loading and if there was a correlation between the degree of end range of motion spinal extension and spinal height gains. DESIGN: Pretest-posttest crossover design is used in this study. SETTING: Study was carried out in research laboratory. SUBJECTS: Forty-one healthy men and women were included in this study. INTERVENTION: Participants were seated in the stadiometer for 5 min with a 4.5-kg weight placed on each shoulder; the load was removed for 5 min and spinal height was measured using a stadiometer before and after 5 min of repetitive or sustained prone press-ups. MAIN MEASURES: Two-by-two repeated-measures ANOVA to identify significant interactions and main effects is used in this study. Significance of alpha = 0.05. A Pearson correlation coefficient was used to assess the correlation between spinal height changes and spinal extension ROM. RESULTS: Participants 24.1 +/- 2.03 years grew using both repetitive (4.85 +/- 3.01 mm) and sustained press ups (4.46 +/- 2.57 mm). There was no significant interaction between the repetitive versus sustained press-ups and the time before and after each prone press-ups strategy and no main effect for strategy (sustained vs. repetitive press-ups). There was a significant main effect for time (before vs. after press-ups) (F(1,30) = 140.771; p < 0.0001; partial eta2 = 0.82). No correlation was found between the degree of end ROM spinal extension and spinal height changes following press-ups strategies. CONCLUSION: Following periods of spinal loading, both repetitive and sustained press-ups increased spinal height. Such strategies could be used to help recover spinal height and limit the effects of decreased spinal height as a result of activities of daily living. PMID- 29469603 TI - Extended local similarity analysis (eLSA) reveals unique associations between bacterial community structure and odor emission during pig carcasses decomposition. AB - Soil burial and composting methods have been widely used for the disposal of pig carcasses. The relationship between bacterial community structure and odor emission was examined using extended local similarity analysis (eLSA) during the degradation of pig carcasses in soil and compost. In soil, Hyphomicrobium, Niastella, Rhodanobacter, Polaromonas, Dokdonella and Mesorhizobium were associated with the emission of sulfur-containing odors such as hydrogen sulfide, methyl mercaptan and dimethyl disulfide. Sphingomonas, Rhodanobacter, Mesorhizobium, Dokdonella, Leucobacter and Truepera were associated with the emission of nitrogen-containing odors including ammonia and trimetylamine. In compost, however, Carnobacteriaceae, Lachnospiaceae and Clostridiales were highly correlated with the emission of sulfur-containing odors, while Rumincoccaceae was associated with the emission of nitrogen-containing odors. The emission of organic acids was closely related to Massilia, Sphaerobacter and Bradyrhizobiaceae in soil, but to Actinobacteria, Sporacetigenium, Micromonosporaceae and Solirubrobacteriales in compost. This study suggests that network analysis using eLSA is a useful strategy for exploring the mechanisms of odor emission during biodegradation of pig carcasses.

PMID- 29469604 TI - Dissolved organic matter and aluminum oxide nanoparticles synergistically cause cellular responses in freshwater microalgae. AB - This study investigated the impact of dissolved organic matters (DOM) on the ecological toxicity of aluminum oxide nanoparticles (Al2O3NPs) at a relatively low exposure concentration (1 mg L-1). The unicellular green alga Scenedesmus obliquus was exposed to Al2O3NP suspensions in the presence of DOM (fulvic acid) at various concentrations (1, 10, and 40 mg L-1). The results show that the presence of DOM elevated the growth inhibition toxicity of Al2O3NPs towards S. obliquus in a dose-dependent manner. Moreover, the combination of DOM at 40 mg L 1 and Al2O3NPs resulted in a synergistic effect. The relative contribution of Al ions released from Al2O3NPs to toxicity was lower than 5%, indicating that the presence of the particles instead of the dissolved ions in the suspensions was the major toxicity sources, regardless of the presence of DOM. Furthermore, DOM at 10 and 40 mg L-1 and Al2O3NPs synergistically induced the upregulation of intercellular reactive oxygen species levels and superoxide dismutase activities. Analysis of the plasma malondialdehyde concentrations and the observation of superficial structures of S. obliquus indicated that the mixtures of DOM and Al2O3NPs showed no significant effect on membrane lipid peroxidation damage. In addition, the presence of both DOM and Al2O3NPs contributed to an enhancement in both the mitochondrial membrane potential and the cell membrane permeability (CMP) in S. obliquus. In particular, Al2O3NPs in the presence of 10 and 40 mg L-1 DOM caused a greater increase in CMP compared to Al2O3NPs and DOM alone treatments. In conclusion, these findings suggest that DOM at high concentrations and Al2O3NPs synergistically interrupted cell membrane functions and triggered subsequent growth inhibition toxicity. PMID- 29469606 TI - Detection of a rare CYP3A4 variant in a transplant patient characterized by a tacrolimus poor metabolizer phenotype. AB - A validated CYP3A genotype classification system allows clustering patients into poor, intermediate and extensive metabolizer phenotypes. However, substantial overlap exists between the clusters. A rare CYP3A4 allele, named CYP3A4*20 (rs67666821), has been specifically described in the Spanish population. The authors investigated the relevance of CYP3A4*20 testing to see if the above mentioned metabolic CYP3A classification system can be improved. In a cohort of 204 kidney transplant recipients, one male patient carrying a CYP3A4*20 allele was detected. This patient was receiving very low doses of tacrolimus to maintain therapeutic levels from day 7 onward when compared with the majority of the patients. These data suggest that this patient should be regarded as a CYP3A-poor metabolizer. PMID- 29469607 TI - Packed in-tube solid phase microextraction with graphene oxide supported on aminopropyl silica: Determination of target triazines in water samples. AB - On-line in-tube solid phase microextraction (in-tube SPME) coupled to high performance liquid chromatography and tandem mass spectrometry (HPLC-MS/MS) was successfully applied to the determination of selected triazines in water samples. The method based on the employment of a packed column containing graphene oxide (GO) supported on aminopropyl silica (Si) showed that the extraction phase has a high potential for triazines extraction aiming to its physical-chemical properties including ultrahigh specific surface area, good mechanical and thermal stability and high fracture strength. Injection volume and loading time were both investigated and optimized. The method validation using Si-GO to extract and concentrate the analytes showed satisfactory results, good sensitivity, good linearity (0.2-4.0 ug L-1) and low detection limits (1.1-2.9 ng L-1). The high extraction efficiency was determined with enrichment factors ranging from 1.2-2.9 for the lowest level, 1.3-4.9 intermediate level and 1.2-3.0 highest level (n = 3). Although the analytes were not detected in the real samples evaluated, the method has demonstrated to be efficient through its application in the analysis of spiked triazines in ground and mineral water samples.

AB - : Acute myeloid leukemia (AML) is a heterogeneous malignant disease. Many different genetic factors can affect a patient's clinical outcome. AIM: The aim of this study was to assess the expression of BCL11A and MDR1 in AML patients, and its relation to clinical outcome. MATERIALS & METHODS: We grouped the 142 patients by the levels of BCL11A and MDR1 and identified three different subgroups: high BCL11A and high MDR1 (n = 47), low BCL11A and low MDR1 (n = 47) and high BCL11A alone or high MDR1 alone (n = 48). RESULTS: The results showed that AML patients with high BCL11A and MDR1 expression had the lowest complete remission and highest relapse rate. The median overall survival of the high BCL11A and high MDR1 group was the shortest among the three groups. With regards to overall survival, there were also significant differences among the groups (p < 0.001). CONCLUSION: High BCL11A and MDR1 expression was associated with a poor response to chemotherapy, and identified a subset of AML patients with a very poor prognosis. PMID- 29469609 TI - Diversity of antibiotic resistance genes and encoding ribosomal protection proteins gene in livestock waste polluted environment. AB - The rapid development and increase of antibiotic resistance are global phenomena resulting from the extensive use of antibiotics in human clinics and animal feeding operations. Antibiotics can promote the occurrence of antibiotic resistance genes (ARGs), which can be transferred horizontally to humans and animals through water and the food chain. In this study, the presence and abundance of ARGs in livestock waste was monitored by quantitative PCR. A diverse set of bacteria and tetracycline resistance genes encoding ribosomal protection proteins (RPPs) from three livestock farms and a river were analyzed through denaturing gradient gel electrophoresis (DGGE). The abundance of sul(I) was 103 to 105 orders of magnitude higher than that of sul(II). Among 11 tet-ARGs, the most abundant was tet(O). The results regarding bacterial diversity indicated that the presence of antibiotics might have an evident impact on bacterial diversity at every site, particularly at the investigated swine producer. The effect of livestock waste on the bacterial diversity of soil was stronger than that of water. Furthermore, a sequencing analysis showed that tet(M) exhibited two genotypes, while the other RPPs-encoding genes exhibited at least three genotypes. This study showed that various ARGs and RPPs-encoding genes are particularly widespread among livestock. PMID- 29469610 TI - Comparative analysis between biofilm formation and gene expression in Staphylococcus epidermidis isolates. AB - AIM: To understand the relationship between ica, aap and bhp gene expression and the implications in biofilm formation in selected clinical and commensal Staphylococcus epidermidis isolates. MATERIAL & METHODS: Isolates were analyzed regarding their biofilm-forming capacity, biochemical matrix composition, biofilm spatial organization and expression of biofilm-related genes. RESULTS: On polysaccharide intercellular adhesin-dependent biofilms, aap and bhp contributions for the biofilm growth were negligible, despite very high levels of expression. In contrast, smaller increases in icaA expression contributed significantly to biofilm growth. Interestingly, no biological differences were observed between clinical and commensal strains. CONCLUSION: These results reinforce the concept that S. epidermidis is an 'accidental pathogen,' and that the ica operon is the main mechanism of biofilm formation in clinical and commensal isolates. PMID- 29469611 TI - Scoring analysis of the men's 2014, 2015 and 2016 world championship tour of surfing: the importance of aerial manoeuvres in competitive surfing. AB - The aim of this study was to investigate the impact of aerial manoeuvres on scoring in professional surfing. 23,631 waves were analysed for the number and types of aerial manoeuvres performed from the 2014, 2015 and 2016 Men's World Championship Tour. Additionally, the awarded score, timing and order of the aerial was also analysed. Descriptive statistics and Two Way ANOVA's were performed with Sidak Multiple Comparisons Post Hoc analysis. Results were a significantly higher score being awarded (P <= 0.0001) when including an aerial in competition across all three seasons. In 2015 surfers were awarded a significantly larger score when performing an air reverse, compared to 2014 (P = 0.0002) and 2016 (P = 0.0057). Surfers were also awarded a higher score for the full rotation aerial in 2015 compared to 2014 (P = 0.0177). In 2015 surfers performing forehand aerials were awarded a greater score than in 2016 (P = 0.0113). The timing of the aerial and score awarded was significantly greater in 2015 as opposed to 2014 when the aerial was their final manoeuvre (P < 0.0001) and when surfers timed the aerial performance early within the heat (P = 0.0027). If a surfer incorporates an aerial manoeuvre during competition, generally speaking, they will be awarded a significantly higher score. PMID- 29469612 TI - The atypical chemokine receptor ACKR2 drives pulmonary fibrosis by tuning influx of CCR2+ and CCR5+ IFNgamma-producing gammadeltaT cells in mice. AB - Chemokines coordinate lung inflammation and fibrosis by acting on chemokine receptors expressed on leukocytes and other cell types. Atypical chemokine receptors (ACKRs) bind, internalize, and degrade chemokines, tuning homeostasis and immune responses. ACKR2 recognizes and decreases the levels of inflammatory CC chemokines. The role of ACKR2 in fibrogenesis is unknown. The purpose of the study was to investigate the role of ACKR2 in the context of pulmonary fibrosis. The effects of ACKR2 expression and deficiency during inflammation and fibrosis were analyzed using a bleomycin-model of fibrosis, ACKR2-deficient mice, bone marrow chimeras, and antibody-mediated leukocyte depletion. ACKR2 was upregulated acutely in response to bleomycin and normalized over time. ACKR2-/- mice showed reduced lethality and lung fibrosis. Bone marrow chimeras showed that lethality and fibrosis depended on ACKR2 expression in pulmonary resident (nonhematopoietic) cells but not on leukocytes. ACKR2-/- mice exhibited decreased expression of tissue-remodeling genes, reduced leukocyte influx, pulmonary injury, and dysfunction. ACKR2-/- mice had early increased levels of CCL5, CCL12, CCL17, and IFNgamma and an increased number of CCR2+ and CCR5+ IFNgamma-producing gammadeltaT cells in the airways counterbalanced by low Th17-lymphocyte influx. There was reduced accumulation of IFNgamma-producing gammadeltaT cells in CCR2-/- and CCR5-/- mice. Moreover, depletion of gammadeltaT cells worsened the clinical symptoms induced by bleomycin and reversed the phenotype of ACKR2-/- mice exposed to bleomycin. ACKR2 controls the CC chemokine expression that drives the influx of CCR2+ and CCR5+ IFNgamma-producing gammadeltaT cells, tuning the Th17 response that mediated pulmonary fibrosis triggered by bleomycin instillation. PMID- 29469613 TI - Aging and anatomical variations in lung tissue stiffness. AB - Lung function is inherently mechanical in nature and depends on the capacity to conduct air and blood to and from the gas exchange regions. Variations in the elastic properties of the human lung across anatomical compartments and with aging are likely important determinants of lung function but remain relatively poorly characterized. Here we applied atomic force microscopy microindentation to characterize human lung tissue from subjects ranging in age from 11 to 60 yr old. We observed striking anatomical variations in elastic modulus, with the airways (200- to 350-um diameter) the stiffest and the parenchymal regions the most compliant. Vessels (diameter < 100 um) represented an intermediate mechanical environment and displayed diameter-dependent trends in elastic modulus. Binning our samples into younger (11-30 yr old) and older (41-60 yr old) groups, we observed significant age-related increases in stiffness in parenchymal and vessel compartments, with the most pronounced changes in the vessels. To investigate cellular mechanisms that might contribute to vascular stiffening with aging, we studied primary human pulmonary artery smooth muscle cells from subjects ranging in age from 11 to 60 yr old. While we observed no change in the mechanical properties of the cells themselves, we did observe trends toward increases in traction forces and extracellular matrix deposition with aging. These results demonstrate age-related changes in tissue mechanical properties that likely contribute to impaired lung function with aging and underscore the potential to identify mechanisms that contribute to mechanical tissue remodeling through the study of human cells and tissues from across the aging spectrum. PMID- 29469615 TI - Enhanced photodynamic therapy using light fractionation against Streptococcus mutans biofilm: type I and type II mechanism. AB - AIM: The objective of the study was to look the efficacy of fractionated light against Streptococcus mutans biofilm. MATERIALS & METHODS: Antibiofilm assays (crystal violet, congo red), electron microscopic, confocal and spectroscopic studies were performed to check the effect of fractionated light. RESULTS: 6-6.5 log10 reduction of planktonic and 3.6-4.2 log10 reduction in biofilm were observed after irradiation with fractionated as compared with continuous light. Increased permeability to propidium iodide and leakage of cellular constituent validate the greater antibiofilm effect of fractionated light. Spectroscopic studies confirmed the relative contribution of type I and type II photochemistry. CONCLUSION: Phenothiazinium dyes have a potential against bacterial biofilm in combination with light fractionation and it offers new opportunities to explore its clinical implication. PMID- 29469614 TI - TGF-beta1-induced deposition of provisional extracellular matrix by tracheal basal cells promotes epithelial-to-mesenchymal transition in a c-Jun NH2-terminal kinase-1-dependent manner. AB - Epithelial cells have been suggested as potential drivers of lung fibrosis, although the epithelial-dependent pathways that promote fibrogenesis remain unknown. Extracellular matrix is increasingly recognized as an environment that can drive cellular responses in various pulmonary diseases. In this study, we demonstrate that transforming growth factor-beta1 (TGF-beta1)-stimulated mouse tracheal basal (MTB) cells produce provisional matrix proteins in vitro, which initiate mesenchymal changes in subsequently freshly plated MTB cells via Rho kinase- and c-Jun NH2-terminal kinase (JNK1)-dependent processes. Repopulation of decellularized lung scaffolds, derived from mice with bleomycin-induced fibrosis or from patients with idiopathic pulmonary fibrosis, with wild-type MTB cells resulted in a loss of epithelial gene expression and augmentation of mesenchymal gene expression compared with cells seeded into decellularized normal lungs. In contrast, Jnk1-/- basal cells seeded into fibrotic lung scaffolds retained a robust epithelial expression profile, failed to induce mesenchymal genes, and differentiated into club cell secretory protein-expressing cells. This new paradigm wherein TGF-beta1-induced extracellular matrix derived from MTB cells activates a JNK1-dependent mesenchymal program, which impedes subsequent normal epithelial cell homeostasis, provides a plausible scenario of chronic aberrant epithelial repair, thought to be critical in lung fibrogenesis. This study identifies JNK1 as a possible target for inhibition in settings wherein reepithelialization is desired. PMID- 29469616 TI - Prehospital Echocardiography During Resuscitation Impacts Treatment in a Physician-Staffed Helicopter Emergency Medical Service: an Observational Study. AB - BACKGROUND: Patients in cardiac arrest must receive algorithm-based management such as basic life support and advanced (cardiac) life support. International guidelines dictate diagnosing and treating any factor that may have caused the arrest or may be complicating the resuscitation. Ultrasound may be of potential value in this process and can be used in a prehospital setting. The objective is to evaluate the use of prehospital ultrasound during traumatic and non-traumatic CPR and determine its impact on prehospital treatment decisions in a Dutch helicopter emergency medical service (HEMS). METHODS: We conducted an observational study in cardiac arrest patients, of any cause, in whom the Nijmegen HEMS performed CPR with concurrent echocardiography. The participating physicians had to adhere to Advanced Life Support protocols as per standard operating procedure. Simultaneous with the interruptions of chest compressions to allow for heart rhythm analysis, ultrasound-trained HEMS physicians performed echocardiography according to study protocol. The HEMS nurse and physician recorded patient data and data on impacted (supported or altered) patient treatment decisions. RESULTS: From February 2014 through November 2016, we included 56 patients who underwent 102 ultrasound examinations. Sixty-two (61%) ultrasound examinations impacted 78 treatment decisions in 49 patients (88%). The impacted treatment was related to termination of CPR in 32 (57%), fluid management (14%), drugs selection and doses (14%), and choice of destination hospital (5%). Causes of cardiac arrest included trauma (48%), cardiac (21%), medical (14%), asphyxia (9%), and other (7%). CONCLUSION: Prehospital echocardiography has an impact on patient treatment and may be a useful tool to support decision-making during CPR in a Dutch HEMS. PMID- 29469617 TI - Are energy Drinks Scapegoats? Decomposing Teenagers' Caffeine intake from Energy Drinks and Soda Beverages. AB - BACKGROUND: Energy drinks have been repeatedly blamed for contributing to caffeine intake among teenagers. OBJECTIVES: This study aimed to estimate and compare the caffeine intake of US teenagers from soda drinks versus energy drinks and shots. METHODS: Data were taken from a 2015 nationally representative survey (Monitoring the Future) of 8th and 10th graders in the US (47.2% 8th grade; 51.1% female). Participants reported their numbers of consumed sodas, diet sodas, energy drinks, and energy shots per day. These were converted into mg caffeine/day and were contrasted with common guidelines for healthy caffeine intake, stratified by age group and sex. Error-bar charts, ANOVA and ROC curves were used for contrasting caffeine intake from soda drinks and energy drinks, as well as their contribution to exceeding recommended caffeine intake cutoffs. RESULTS: First, in both sexes and grades the intake from soda drinks was significantly higher than the intake from energy drinks. The soda and energy drink intake for males was higher than the intake for females; intake for 8th graders was higher than this of 10th graders. Second, caffeine intake from soda drinks was significantly higher even in those who exceeded the recommended maximum caffeine intake. Third, caffeine intakes from soda and energy drinks were efficacious in explaining the exceeding of the recommended threshold for daily caffeine intake, but the explanatory power of soda drinks was larger. CONCLUSIONS: From a caffeine consumption standpoint, health professionals should emphasize reduction in both soda and energy drinks. PMID- 29469618 TI - Elastic TPU Mesh as Abdominal Wall Inlay Significantly Reduces Defect Size in a Minipig Model. AB - BACKGROUND: The open abdomen with mesh implantation, followed by early reoperation with fascial closure, is a modern surgical approach in difficult clinical situations such as severe abdominal sepsis. As early fascial closure is not possible in many cases, mesh-mediated fascial traction is helpful for conditioning of a minimized ventral hernia after open abdomen. The aim of this study was to evaluate the clinical utilization of an innovative elastic thermoplastic polyurethane mesh (TPU) as an abdominal wall inlay in a minipig model. METHODS: Ten minipigs were divided in two groups, either receiving an elastic TPU mesh or a nonelastic polyvinylidene fluoride (PVDF) mesh in inlay position of the abdominal wall. After 8 weeks, mesh expansion and abdominal wall defect size were measured. Finally, pigs were euthanized and abdominal walls were explanted for histological and immunohistochemical assessment. RESULTS: Eight weeks after abdominal wall replacement, transversal diameter of the fascial defect in the TPU group was significantly smaller than in the PVDF group (4.5 cm vs. 7.4 cm; p = 0.047). Immunhistochemical analysis showed increased Ki67 positive cells (p = 0.003) and a higher number of apoptotic cells (p = 0.047) after abdominal wall replacement with a TPU mesh. Collagen type I/III ratio was increased in the PVDF group (p = 0.011). CONCLUSION: Implantation of an elastic TPU mesh as abdominal wall inlay is a promising approach to reduce the size of the ventral hernia after open abdomen by mesh-mediated traction. However, this effect was associated with a slightly increased foreign body reaction in comparison to the nonelastic PVDF. PMID- 29469619 TI - Visual search in unilateral spatial neglect: The effects of distractors on a dynamic visual search task. AB - The objective of this study was to examine visual scanning performance in patients with Unilateral Spatial Neglect (USN) in a visual search task. Thirty one right hemisphere stroke patients with USN were recruited. They performed a dynamic visual search task with two conditions, with and without distractors, while eye movements were monitored with an eye-tracker. The main goal of the task was to select target stimuli that appeared from the top of the screen and moved vertically downward. Target detection and visual scanning percentage were assessed over two hemispaces (right, left) on two conditions (distractor, no distractor). Most Scanned Regions (MSR) were calculated to analyze the areas of the screen where most points of fixation were directed to. Higher target detection rate and visual scanning percentages were found on the right hemispace on both conditions. From the MSRs we found that participants with a center of attention further to the right of the screen also presented smaller overall MSRs. Right hemisphere stroke patients with USN presented not only a significant rightward bias but reduced overall search areas, implying hyperattention does not only restrict search on the horizontal (right-left) axis but the vertical axis (top-bottom) too.

AB - PURPOSE: To report the results of a hybrid approach to aortic arch repair using an innovative unibody double-branched stent graft in a canine model. MATERIALS AND METHODS: The stent-graft system consists of two parts: the main body and two branches for reconstruction of the supra-arch branches. There is a 2-cm-long suturing portion at the proximal end of the main body. Twenty adult German sheep dogs underwent a hybrid surgical treatment to place the stent-grafts into the proximal descending aorta and the supra-arch branches. Outcomes were assessed by operative mortality, complications, imaging studies, and histomorphometric analyses. RESULTS: Placement of the stent-graft was performed successfully in all dogs without complications. One dog died of respiratory failure due to early extubation. The other dogs survived to 6 months without complications, at which time they were sacrificed. The mean cardiopulmonary bypass time was 80.3 +/- 7.3 mins and hypothermic circulatory arrest time was 10.7 +/- 1.9 min. The average blood loss was 373.5 mL. At 6 months, postoperative aortic imaging indicated that the main body and branches of the stent-graft were fully open and in satisfactory position. No migration, deformation, or endovascular leakage was observed. Histomorphometric results showed normal arrangement of medial and adventitial elastic fibers, moderately proliferated intima, with or without neo-microvessels, and microscopic morphological changes in internal elastic lamina. CONCLUSIONS: These results demonstrate that it is possible and safe to reconstruct the aortic arch with the novel open-branched stent-graft placement. PMID- 29469633 TI - Outpatient Addiction Treatment for Problematic Alcohol Use: What Makes Patients Who Dropped Out Different from Those Who Did Not? AB - BACKGROUND: A minority of individuals with problematic alcohol use effectively seek help. Moreover, dropouts from care are not uncommon. It remains a major concern for health professionals, as adherence to treatment is significantly associated with better physical and psychological outcomes. OBJECTIVES: The main aim of this research was to assess what factors could distinguish patients with problematic alcohol use who dropped out from those who did not. METHODS: The sample included 150 patients followed-up in an outpatient treatment center in France for a problematic alcohol use. Two measurement times were planned: at the first appointment and after six month of treatment. A large set of individual, environmental and institutional variables were considered to compare both subgroups. RESULTS: Patients who dropped out mostly differ from patients who did not with a higher level of alcohol-related problems, ambivalence, inclinations to use the substance, number of missed appointments. Significant results were also observed regarding a lower time gap between the first contact with the center and the first appointment, as well as the season of the last appointment. CONCLUSIONS: Tailored motivational interventions could be offered to ambivalent patients, especially during the beginning of the treatment and some significant periods of the year. A particular focus should be brought on patients presenting such profiles in terms of level of alcohol problems, inclinations to drink and motivation to change. Overall, the study provides elements to better understand what may bring one patient to drop out of the treatment, and to improve the continuity of care. PMID- 29469634 TI - Placenta structural changes in heavy smoking mothers: a stereological aspect. AB - OBJECTIVE: Smoking during pregnancy is able to alter the structure and function of the placenta. In the present study, quantitative changes of the placenta in smoking mothers were investigated compared to healthy controls by Cavalieri's point counting method. METHODS: Twenty placentas from heavy smoking mothers and non-smoker controls (n = 10 in each group) were selected. Systematic uniform random sampling (SURS) was used for sample selection and tissue sectioning. Quantitative parameters of the placenta in the selected sections were estimated after Masson's trichrome staining. Differences between the two groups were determined by the Mann Whitney U test and the significance level was set at p < .05. RESULTS: Results showed that there was a significant difference in the placental weight, total volume of placenta, intervillous space, fibrin and syncytiotrophoblast between the heavy smoker group and the control group (p < .05). The differences in the volume density of fibrin and blood vessels between the smoker and control groups were statistically significant (p < .05). CONCLUSIONS: Our findings suggested that quantitative parameters of the placenta significantly changed in placentas from the smoker group compared to controls. These changes can probably be associated with pregnancy complications in smoking mothers and may affect the development and survival of the fetus and even its future life. PMID- 29469635 TI - In the Experimental Model of Acute Mesenteric Ischemia, The Correlation of Blood Diagnostic Parameters with the Duration of Ischemia and their Effects on Choice of Treatment. AB - : Purpose/Aim: Acute mesenteric ischemia is a syndrome characterized by sudden onset abdominal pain followed by intestinal necrosis. Morbidity and mortality increase with delayed diagnosis. Even with the latest radiological diagnostic methods, early diagnosis and initiation of treatment can be delayed. Using an experimental model, here we aim to determine the relationship between the laboratory parameters used to detect acute mesenteric ischemia and the duration of irreversible ischemia. MATERIALS AND METHODS: A total of 30 male Wistar albino rats were divided into five groups, all of which underwent general anesthesia: (i) Superior mesenteric artery (SMA) dissection with laparotomy was performed, and blood samples and intestinal segment samples were taken after 2 hr (Sham group); (ii) volvulus of one-third of the small intestines was performed manually by laparotomy, and blood samples and intestinal segment samples were taken after 2 hr (Volvulus group); (iii) SMA was ligated with laparotomy, and blood samples and intestinal segment samples were taken after 2 hr (SMA+ligated 2-hr group); (iv) SMA was ligated with laparotomy, and blood samples and intestinal segment samples were taken after 4 hr (SMA+ligated 4-hr group); and (v) SMA was ligated with laparotomy, and blood samples and intestinal segment samples were taken after 6 hr (SMA+ligated 6-hr group). RESULTS: The mean lactate dehydrogenase (LDH) activities of the SMA+ligated 2-hr and SMA+ligated 6-hr groups were statistically higher than the control group (p = .004). Compared to the Sham and Volvulus groups, the mean lactate level of the SMA+ligated 6-hr group was significantly higher (p = .004). Compared to the Sham and Volvulus groups, the mean D-dimer levels of the SMA+ligated 4-hr and SMA+ligated 6-hr groups were significantly higher (p = .004 and .003, respectively). By histopathological evaluation, we found that pathological damage increased as the ischemia lengthened. CONCLUSIONS: Mesenteric ischemia leads to an irreversible loss of intestinal perfusion and an increase in parameters of ischemia. Irreversible tissue damage occurs after 4 hr of ischemia and peaks after 6 hr, whereas parameters of ischemia (D-dimer, LDH, and L-Lactate levels) are highest at 2 hr after the onset of ischemia. PMID- 29469636 TI - Total Colpectomy Increases the Risk of Postoperative Hydronephrosis in Vaginal Cancer Patients. AB - PURPOSE: Due to the rarity of vaginal cancer, surgical treatment results, and postoperative complications have been poorly described in the literature. The aim of this study was to improve current knowledge about the incidence of hydronephrosis following the surgical treatment of vaginal cancer. MATERIALS AND METHODS: 32 patients with vaginal cancer of the middle and upper third were matched with 32 cervical cancer patients (stages I and II) for comparison of long term urological postoperative complications. All patients underwent radical surgical treatment and all stage II patients underwent neoadjuvant radiotherapy. RESULTS: Hydronephrosis had a significantly higher incidence in the vaginal cancer group (p = 0.04), with 14 patients (43.8%) being diagnosed with this complication compared to only 5 patients (15.6%) in the cervical cancer group. Among patients that received radiotherapy, 40.1% (n = 9) and 22.7% ( = 5) of vaginal, respectively cervical cancer patients were found with postoperative hydronephrosis. CONCLUSIONS: In vaginal cancer patients total colpectomy increases the risk of developing postoperative hydronephrosis, especially if neoadjuvant radiotherapy has been applied. PMID- 29469637 TI - Mental illness in Sweden (1896-1905) reflected through case records from a local general hospital. AB - Mental illness in a hospital in a medium-sized town in Sweden was studied. Consecutive case records from 1896 to 1905, and also from 2011, were selected. In the historical sample, neurasthenia was the most common diagnosis, followed by affective disorders and alcohol abuse. ICD-10 diagnoses corresponded well with the historical diagnoses. Melancholia resembled modern criteria for depression. Mania, insania simplex and paranoia indicated more severe illness. Abuse was more common among men and hysteria among women. Those with a medical certificate for mental hospital care were very ill and showed no gender difference. There were no diagnoses for abuse, but 17% had a high level of alcohol consumption. The pattern of signs and symptoms displayed by patients does not appear to change with time. PMID- 29469638 TI - Cost comparison of continued anticoagulation with rivaroxaban versus placebo based on the 1-year EINSTEIN-Extension trial efficacy and safety results. AB - AIMS: The EINSTEIN-Extension trial (EINSTEIN-EXT) found that continued treatment with rivaroxaban for an additional 6 or 12 months (vs placebo) after 6-12 months of initial anticoagulation significantly reduced the risk of recurrent venous thromboembolism (VTE) with a small non-significant increased risk of major bleeding (none fatal or in critical site). This study aimed to compare total healthcare cost between rivaroxaban and placebo, based on the EINSTEIN-EXT event rates. METHODS: Total healthcare cost was calculated as the sum of treatment and clinical event costs from a US managed care perspective. Treatment duration and event rates were obtained from the EINSTEIN-EXT study. Adjustment on treatment duration was made by assuming a 10% non-adherence rate. Drug costs were based on wholesale acquisition costs. Cost estimates for clinical events (i.e. recurrent deep vein thrombosis [DVT], recurrent pulmonary embolism, major bleeding, clinically relevant non-major bleeding) were determined from the literature. Results were examined over a +/-20% range of each cost component and over 95% confidence intervals (CIs) of event rate differences in deterministic (one-way) and probabilistic sensitivity analyses (PSA). RESULTS: Total healthcare cost was $1,454 lower for rivaroxaban-treated (vs placebo-treated) patients in the base case, with a lower clinical event cost fully offsetting drug cost. The cost savings of recurrent DVT alone (-$3,102) was greater than drug cost ($2,723). Total healthcare cost remained lower for rivaroxaban in the majority (73%) of PSA (cost difference [95% CI] = -$1,454 [-$2,396, $1,231]). LIMITATIONS: This study was conducted over the 1-year observation period of the EINSTEIN-EXT trial, which limited "real-world" applicability and examination of long-term economic impact. Assumptions on drug and clinical event costs were US-based and, thus, not applicable to other healthcare systems. CONCLUSIONS: Total healthcare costs were estimated to be lower for patients continuing rivaroxaban therapy compared to those receiving placebo in VTE patients who had completed 6-12 months of VTE treatment. PMID- 29469640 TI - Detecting malingering in traumatic brain injury: combining response time with performance validity test accuracy. AB - OBJECTIVE: The present study examined the incremental utility of item-level response time (RT) variables on a traditional performance validity test in distinguishing adults with verified TBI from adults coached to feign neurocognitive impairment. METHOD: Participants were 45 adults with moderate to severe TBI, 45 healthy adults coached to feign neurocognitive impairment (SIM), and 61 healthy adult comparisons providing full effort (HC). All participants completed a computerized version of the Test of Memory Malingering (TOMM-C) in the context of a larger test battery. RT variables examined along with TOMM-C accuracy scores included mean RTs (Trial 1, Trial 2, correct and incorrect trials) and RT variability indices. RESULTS: Several RT indices differed significantly across the groups. In general, SIM produced longer, more variable RTs than HC and TBI. Of the RT indices, average RT for Trial 1 and 2 were the best predictors of group membership; however, classification accuracies were greatly influenced by the groups being compared. Average RT for Trial 1 and 2 showed excellent discrimination of SIM and HC. All RT indices were less successful in discriminating SIM and TBI. Average RT for Trial 1 and 2 added incremental predictive value to TOMM-C accuracy in distinguishing SIM from TBI. CONCLUSION: Findings contribute to a limited body of research examining the incremental utility of combining RT with traditional PVTs in distinguishing feigned and bona fide TBI. Findings support the hypothesis that combining RT with TOMM-C accuracy can improve its diagnostic accuracy. Future research with other groups of clinical interest is recommended.

AB - While the variety of engineered nanoparticles used in consumer products continues to grow, the use of metal oxide nanoparticles in electronics, textiles, cosmetics and food packaging industry has grown exponentially in recent years, which will inevitably result in their release into wastewater streams in turn impacting the important biological processes in wastewater treatment plants. Among these processes, nitrification play a critical role in nitrogen removal during wastewater treatment, however, it is sensitive to a wide range of inhibitory substances including metal oxide nanoparticles. Therefore, it is essential to systematically asses the effects of metal oxide nanoparticles on nitrification in biological wastewater treatment systems. In this review we discuss the present scenario of metal oxide nanoparticles and their impact on biological wastewater treatment processes, specifically nitrogen removal through nitrification. We also summarize the various methods used to measure nitrification inhibition by metal oxide nanoparticles and highlight corresponding results obtained using those methods. Finally, the key research gaps that need to be addressed in future are discussed.

AB - BACKGROUND: Palliative care patients are inherently difficult to recruit to and retain on studies. Even when patients are recruited, it is hard to complete studies with sufficient data. There is a dearth of literature specific to men with castrate resistant prostate cancer (CRPC) and the clinical trials coordinator/research nurse's perspective in improving trial outcomes in palliative care. Objectives To describe the lessons learnt (by the nursing research team) from a prospective cohort study of men with CRPC and the practical implications for future research in this area. METHODS: A pilot feasibility cohort study that followed patients with CRPC from referral until death. The participants completed questionnaires while the researcher documented treatments, disease status and symptom burden. The recruitment methods, data quality and results were analysed. RESULTS AND DISCUSSION: Several lessons have been learnt with regard to facilitating trial recruitment and design. These lessons are: the importance of building relationships with local urology teams, including all men with the diagnosis of CRPC as documented by a medical oncologist or urologist, reducing questionnaire burden, capturing symptom scores in clinic, actively following up patients by phone, and recording all reasons for drop-out or lost to follow-up. These lessons can now be implemented to improve future studies involving this demographic. PMID- 29469642 TI - Implementing an integrated pathway to care for the dying: is your organisation ready? AB - BACKGROUND: Integrated pathways for care of the dying aim to promote the delivery of high-quality palliative care, regardless of access to specialist services. AIM: To produce a heuristic technique to assist with planning and evaluating the integration of the care of the dying pathway into everyday work. METHODS: Electronic databases were searched to identify research papers focused on the implementation of integrated pathways for care of the dying in acute hospital settings. RESULTS: A total of 13 articles were reviewed using the four elements of normalisation process theory-coherence, cognitive participation, collective action and reflexive monitoring. These results informed the development of a heuristic for organisational readiness. CONCLUSION: The organisational readiness heuristic provides an evidence-based checklist for organisational leaders who are planning to introduce new, or evaluate current, integrated pathways for care of the dying. The next step is to trial the heuristic for feasibility in practice. PMID- 29469644 TI - Research roundup. AB - Synopses of a selection of recently published research articles of relevance to palliative care. PMID- 29469643 TI - Targeted palliative care day therapy interventions using modified MYMOP2 tool can improve outcomes for patients with non-malignant diseases. AB - BACKGROUND: There is a paucity of evidence supporting the benefits of palliative care day therapy services for patients with non-malignant diseases. Outcome measures in this setting are also lacking. AIM: To evaluate the use of the modified Measure Yourself Medical Outcome Profile 2 (MYMOP2) tool in tailoring day therapy services toward the needs of patients with non-malignant conditions Method: A single system, 'before and after' design quality improvement study was conducted. Data were collected regarding outcome measures, re-referral rates and mortality. RESULT: After the introduction of the modified MYMOP2 tool, there was an improvement in the mean outcome scores for patients with non-malignant disease. Re-referral rates for these patients dropped by 28% during the follow up period, with no change in mortality. IMPLICATIONS FOR PRACTICE: These findings suggest that using the modified MYMOP2 tool to tailor and measure the outcome of holistic day therapy services results in a more sustained improvement for patients with non-malignant disease. PMID- 29469645 TI - Spirituality among family caregivers in palliative care: an integrative literature review. AB - BACKGROUND: Family caregivers experience spiritual and existential concerns while caring for their terminally ill family members. AIM: To evaluate and synthesise studies on spirituality among family caregivers in palliative care. DESIGN: An integrative literature review of peer-reviewed articles published between 2000 and 2016. SAMPLE: Participants were family caregivers (parents, spouses, relatives or friends) caring for an adult (age>18 years) family member with a terminal illness in a palliative care setting. RESULTS: Data from 26 published research papers were systematically analysed. Five themes were identified regarding spirituality and family caregiving: a close and meaningful connection, spirituality as a way of coping, spiritual needs and expressions among family caregivers, spirituality to transcend fears, and spirituality in family caregivers' decision-making. IMPLICATIONS FOR PRACTICE: Nurses are encouraged to explore the spirituality and spiritual experiences of family caregivers to support their spiritual wellbeing while caring for their terminally ill family members.

PMID- 29469647 TI - How skilled do Israeli nurses perceive themselves to be in providing palliative care? Results of a national survey. AB - BACKGROUND: In Israel, palliative care (PC) services are limited. This study assessed Israeli nurses' perceived competencies and educational needs in providing PC. DESIGN: Online administration of the End-of-Life Professional Caregiver Survey (EPCS). SETTING/SUBJECTS: Oncology and PC nurses were identified through the Israel Ministry of Health and Oncology Nurses' Society. MEASUREMENTS: Demographic and practice data were analysed using analysis of variance tests to determine differences between nurse characteristics by EPCS domains. RESULTS: The sample (n=105) was 94% female, had a mean age of 48 years (SD=10.5) and 83% were Jewish Israeli. Thirty-nine percent reported PC training in nursing school and 42% felt their workplace provided little to no PC education and resources to nurses. Those with advanced degrees and those who received post-graduate PC training had higher mean scores across EPCS domains (p<0.05 for all). CONCLUSIONS: Nursing education and workplace support in PC for Israeli nurses are limited. It is hoped that these findings may inform future PC nursing education and policy in Israel. PMID- 29469648 TI - Imprecise communication and perceptions of palliative care. PMID- 29469649 TI - A new way of organising palliative care for patients with severe chronic obstructive pulmonary disease. AB - Patients with chronic obstructive pulmonary disease (COPD) often live with unmet palliative needs and low quality of life, although several guidelines recommend that those with COPD should be offered early and integrated palliative care. However, none of the guidelines describe how these recommendations can be operationalised and the current literature offers little information about experiences with developing and implementing new palliative care services. This article offers insight into the experience of developing and implementing a new palliative outpatient structure for patients with severe COPD. All patients are assigned to a nurse who has overall responsibility for establishing and maintaining an individualised relationship with the patient and identifying their needs for care and treatment. Routine outpatient visits are replaced by ad hoc consultations, and patients are seen by pulmonary specialists only when there is a need for medical assessment and treatment or a planned advanced care planning dialogue. The new service was succesfully implemented; however, the changes required good multidisciplinary collaboration, dedicated health professionals and managerial support. This paper highlights the need for further studies to investigate the effectiveness of new palliative care interventions for patients with COPD. PMID- 29469651 TI - "I'm Scared of the Disappointment": Young Adult Smokers' Relational Identity Gaps and Management Strategies as Sites of Communication Intervention. AB - While cigarette smoking is decreasing among young adults, rates of nicotine consumption through other devices, most notably electronic cigarettes, are on the rise. Framed by communication theory of identity, this study examines young adult smokers' experiences with relational others in regard to their smoking. Focus group discussions and individual interviews convened with 20 young adult cigarette and electronic cigarette smokers revealed identity gaps implicating the relational layer of identity, including personal-relational, enacted-relational, and personal-enacted-relational identity gaps. Participants used communicative and behavioral strategies to manage relational discrepancies. The documented identity gaps and management strategies present opportunities for targeted smoking cessation interventions that amplify dissonance created through identity gaps as a motivational tactic. PMID- 29469652 TI - Effects of the ammonium loading rate on nitrite-oxidizing activity during nitrification at a high dose of inorganic carbon. AB - In this study, the effects of the ammonium loading rate (ALR) and inorganic carbon loading rate (ILR) on the nitrification performance and composition of a nitrifying bacterial community were investigated in a moving bed biofilm reactor, using poly(vinyl alcohol) (PVA) sponge cubes as a supporting carrier. Between the two ALRs of 0.36 and 2.16 kg-N m-1 d-1, stable partial nitritation was achieved at the higher ALR. Inorganic carbon was dosed at high levels: 33.1, 22.0, 16.4, 11.0, and 5.4 times the theoretical amount. Nonetheless, nitrification efficiency was not affected by the ILR at the two ALRs. Quantitative PCR analysis of ammonia and nitrite-oxidizing bacteria revealed that ALR is an important determinant of partial nitritation by accumulating ammonia-oxidizing bacteria in the nitrification system. In comparison, two nitrite-oxidizing bacterial genera (Nitrobacter and Nitrospira) showed almost the same relative abundance at various ALRs and ILRs. Terminal restriction fragment length polymorphism targeting the gene of ammonia monooxygenase subunit A revealed that Nitrosomonas europaea dominated under all conditions. PMID- 29469650 TI - Prenatal androgen exposure causes hypertension and gut microbiota dysbiosis. AB - BACKGROUND: Conditions of excess androgen in women, such as polycystic ovary syndrome (PCOS), often exhibit intergenerational transmission. One way in which the risk for PCOS may be increased in daughters of affected women is through exposure to elevated androgens in utero. Hyperandrogenemic conditions have serious health consequences, including increased risk for hypertension and cardiovascular disease. Recently, gut dysbiosis has been found to induce hypertension in rats, such that blood pressure can be normalized through fecal microbial transplant. Therefore, we hypothesized that the hypertension seen in PCOS has early origins in gut dysbiosis caused by in utero exposure to excess androgen. We investigated this hypothesis with a model of prenatal androgen (PNA) exposure and maternal hyperandrogenemia by single-injection of testosterone cypionate or sesame oil vehicle (VEH) to pregnant dams in late gestation. We then completed a gut microbiota and cardiometabolic profile of the adult female offspring. RESULTS: The metabolic assessment revealed that adult PNA rats had increased body weight and increased mRNA expression of adipokines: adipocyte binding protein 2, adiponectin, and leptin in inguinal white adipose tissue. Radiotelemetry analysis revealed hypertension with decreased heart rate in PNA animals. The fecal microbiota profile of PNA animals contained higher relative abundance of bacteria associated with steroid hormone synthesis, Nocardiaceae and Clostridiaceae, and lower abundance of Akkermansia, Bacteroides, Lactobacillus, Clostridium. The PNA animals also had an increased relative abundance of bacteria associated with biosynthesis and elongation of unsaturated short chain fatty acids (SCFAs). CONCLUSIONS: We found that prenatal exposure to excess androgen negatively impacted cardiovascular function by increasing systolic and diastolic blood pressure and decreasing heart rate. Prenatal androgen was also associated with gut microbial dysbiosis and altered abundance of bacteria involved in metabolite production of short chain fatty acids. These results suggest that early-life exposure to hyperandrogenemia in daughters of women with PCOS may lead to long-term alterations in gut microbiota and cardiometabolic function. PMID- 29469653 TI - Analytical similarity assessment of rituximab biosimilar CT-P10 to reference medicinal product. AB - CT-P10 (TruximaTM) was recently approved as the world's first rituximab biosimilar product in the European Union (EU) and South Korea. To demonstrate biosimilarity of CT-P10 with the reference medicinal product (RMP), extensive 3 way similarity assessment has been conducted between CT-P10, EU-Rituximab and US Rituximab, focusing on the physicochemical and biological quality attributes. A multitude of state-of-the-art analyses revealed that CT-P10 has identical primary and higher order structures compared to the original product. Purity/impurity profiles of CT-P10 measured by the levels of aggregates, fragments, non glycosylated form and process-related impurities were also found to be comparable with those of RMPs. In terms of the post-translational modification, CT-P10 contains slightly less N-terminal pyro-glutamate variant, which has been known not to affect product efficacy or safety. Oligosaccharide profiling has revealed that, although CT-P10 contains the same conserved glycan species and relative proportion with the RMPs, the content of total afucosylated glycan in CT-P10 was slightly higher than in EU- or US-Rituximab. Nevertheless, the effect of the observed level of afucosylation in CT-P10 drug product on Fc receptor binding affinity or antibody-dependent cell-mediated cytotoxicity was found to be negligible based on the spiking study with highly afucosylated sample. Arrays of biological assays representative of known and putative mechanisms of action for rituximab have shown that biological activities of CT-P10 are within the quality range of RMPs. Recent results of clinical studies have further confirmed that the CT-P10 exhibits equivalent clinical efficacy and safety profiles compared to EU- and US-Rituximab. The current 3-way similarity assessment together with clinical study results confidently demonstrate that CT-P10 is highly similar with EU- and US-Rituximab in terms of physicochemical properties, biological activities, efficacy, and safety for its final approval as a biosimilar product. PMID- 29469654 TI - The effect of pre-exercise ingestion of corinthian currant on endurance performance and blood redox status. AB - The present study investigated the effect of Corinthian currant pre-exercise supplementation on metabolism, performance and blood redox status during, and after prolonged exercise. Eleven healthy participants (21-45y) performed a 90-min constant-intensity (60-70% VO2max) submaximal-trial, plus a time-trial (TT) to exhaustion (95% VO2max) after consuming an isocaloric (1.5g CHO/kg BM) amount of randomly assigned Corinthian currant or glucose-drink, or water (control). Blood was drawn at baseline, pre-exercise, 30min, 60min, 90min of submaximal-trial, post-TT, and 1h post-TT. Post-ingestion blood glucose (GLU) under Corinthian currant was higher compared with water, and similar compared with glucose-drink throughout the study. Respiratory quotient under Corinthian currant was similar with glucose-drink and higher than water throughout the submaximal trial. Accordingly, higher CHO and lower fat oxidation were observed under Corinthian currant compared with water. The TT performance was similar between Corinthian currant, glucose-drink and water. Redox status were similar under all three conditions. Reduced glutathione (GSH) declined while total antioxidant capacity (TAC) and uric acid increased during exercise. GSH and TAC returned to baseline, while uric acid remained increased the following 1h. Corinthian currant, although did not alter exercise-mediated redox status changes and performance, was equally effective to a glucose-drink in maintaining GLU levels during prolonged cycling. PMID- 29469655 TI - Valentin Magnan and Sergey Korsakov: French and Russian pioneers in the study of alcohol abuse. AB - This study focuses on two outstanding psychiatrists: the Frenchman Valentin Magnan (1835-1916) and the Russian Sergey Korsakov (1854-1900). Their international renown is primarily associated with their investigations into health consequences of alcohol consumption; they were pioneers in this field, and happened to know each other well. The similarities and differences are shown in social and scientific approaches adopted by these two scientists. In his work, Magnan focused mainly on absinthe and epilepsy; he considered alcoholism to be a hereditary mental disorder. Korsakov, after a period of work in Paris under Magnan's guidance, represented a more modern generation and was advancing fundamental ideas on the nature of psychoses and merging clinical features, somatic, psychological, and social factors. Although Magnan has practically disappeared from the current literature on alcoholism, Korsakov is still clearly present today.

PMID- 29469661 TI - Biological Evidence Regarding Psychopathy Does Not Affect Mock Jury Sentencing. AB - Research on the biological factors influencing criminal behavior is increasingly being introduced into court, necessitating research on how such evidence is perceived and influences decision makers. Research on how this evidence influences sentencing recommendations is inconclusive. In this study, we focus on biological evidence related to psychopathy, a construct commonly associated with criminal behavior. Approximately 800 community members were presented with a case vignette detailing an individual who is described as having a high level of psychopathic traits. Participants received either psychological information about psychopathy (i.e., no biological evidence), evidence the defendant had genetic risk factors for psychopathy, or written neuroimaging evidence the defendant had brain deficits associated with psychopathy. Participants then recommended a sentence. Overall, recommended sentence lengths did not differ between evidence conditions. These findings add to a growing body of research suggesting that biological evidence may not have as much of an influence on jurors as previously thought. PMID- 29469663 TI - A Neuroscience-Oriented Research Approach to Borderline Personality Disorder. AB - Traditionally, the study of personality disorders had been based on psychoanalytic or behavioral models. Over the past two decades, there has been an emerging neuroscience model of borderline personality disorder (BPD) grounded in the concept of BPD as a condition in which dysfunctional neural circuits underlie its pathological dimensions, some of which include emotion dysregulation (broadly encompassing affective instability, negative affectivity, and hyperarousal), abnormal interpersonal functioning, and impulsive aggression. This article, initiated at a joint Columbia University-Cornell University Think Tank on BPD with representation from the Icahn School of Medicine at Mount Sinai, suggests how to advance research in BPD by studying the dimensions that underlie BPD in addition to studying the disorder as a unitary diagnostic entity. We suggest that linking the underlying neurobiological abnormalities to behavioral symptoms of the disorder can inform a research agenda to better understand BPD with its multiple presentations. PMID- 29469664 TI - Mentalization in Adolescents With Borderline Personality Disorder: A Comparison With Healthy Controls. AB - Mentalization is proposed to underlie the disturbed interpersonal relatedness that is a hallmark of borderline personality disorder (BPD). Despite growing evidence of BPD in adolescents, studies examining mentalization in relation to adolescent BPD have remained limited. Given contradictory findings of this relationship, particularly with adults, further research of mentalization in adolescents with BPD is warranted. The current study further clarifies the nature of mentalizing impairments, related to BPD, by examining different aspects of mentalization between adolescents with BPD (n = 26) and a group of healthy controls (n = 25). Findings support studies that suggest that mentalization may be an important treatment target, influencing BPD symptoms and interpersonal functioning in adolescents with BPD. They also support the importance of examining mentalizing abilities in relation to varying levels of complexity, interpersonal contexts, and levels of arousal. Limitations and further research are discussed. PMID- 29469662 TI - A Recurrent Question: What Is Borderline? AB - The status of borderline personality disorder (BPD) as a diagnostic category is a matter of continuing controversy. In the United States, BPD is one of the most frequent diagnoses of psychiatric inpatients, and a similar tendency emerges in Europe. Nearly all theoretical aspects of BPD have been questioned, including its very position as a personality disorder. In this article, we trace the evolution of the borderline concept from the beginning of the 20th century to the current psychometric research. We argue that the status of BPD is fraught with conceptual difficulties, including an unrecognized semantic drift of major phenomenological terms (e.g., identity), a lack of general principles for the distinction of BPD and the major psychiatric syndromes (e.g., schizophrenia spectrum disorders), and insufficient definitions of key nosological concepts. These difficulties illustrate general problems in today's psychiatry that require consideration. PMID- 29469657 TI - Direct mass spectrometric characterization of disulfide linkages. AB - Disulfide linkage is critical to protein folding and structural stability. The location of disulfide linkages for antibodies is routinely discovered by comparing the chromatograms of the reduced and non-reduced peptide mapping with location identification confirmed by collision-induced dissociation (CID) mass spectrometry (MS)/MS. However, CID product spectra of disulfide-linked peptides can be difficult to interpret, and provide limited information on the backbone region within the disulfide loop. Here, we applied an electron-transfer dissociation (ETD)/CID combined fragmentation method that identifies the disulfide linkage without intensive LC comparison, and yet maps the disulfide location accurately. The native protein samples were digested using trypsin for proteolysis. The method uses RapiGest SF Surfactant and obviates the need for reduction/alkylation and extensive sample manipulation. An aliquot of the digest was loaded onto a C4 analytical column. Peptides were gradient-eluted and analyzed using a Thermo Scientific LTQ Orbitrap Elite mass spectrometer for the ETD-triggered CID MS 3 experiment. Survey MS scans were followed by data dependent scans consisting of ETD MS2 scans on the most intense ion in the survey scan, followed by 5 MS3 CID scans on the 5 most intense ions in the ETD MS2 scan. We were able to identify the disulfide-mediated structural variants A and A/B forms and their corresponding disulfide linkages in an immunoglobulin G2 monoclonal antibody with lambda light chain (IgG2lambda), where the location of cysteine linkages were unambiguously determined. PMID- 29469665 TI - Psychopathy and Internalizing Psychopathology: A Triarchic Model Perspective. AB - Methodological and conceptual differences across studies have impeded our understanding of the relationship between psychopathy and internalizing psychopathology. To shed further light on this question, we undertook correlational and structural-modeling analyses of data from two samples to characterize how facets of psychopathy relate to internalizing psychopathology when assessed using multidimensional measures of each construct (i.e., Triarchic Psychopathy Measure, Inventory of Depression and Anxiety Symptoms). Participants for Study 1 were 470 undergraduates and community-dwelling adults who completed these measures in self-report form; participants for Study 2 were 301 community dwelling adults who completed informant-rating versions of these measures (as applied to a known-other). Across samples, analyses revealed sharply contrasting associations for the three triarchic-model facets with internalizing psychopathology and its subdomains, with boldness relating negatively in most cases, disinhibition relating positively in most cases, and meanness exhibiting mostly null associations. Results provide a nuanced picture of associations between psychopathic symptomatology and internalizing problems. PMID- 29469658 TI - Evolving Treatment Patterns of NFL Players by Orthopaedic Team Physicians Over the Past Decade, 2008-2016. AB - BACKGROUND: Previous studies have analyzed the treatment patterns used to manage injuries in National Football League (NFL) players. HYPOTHESIS: Treatment patterns for injuries in NFL players will have changed over the study period. STUDY DESIGN: Descriptive epidemiology study. LEVEL OF EVIDENCE: Level 5. METHODS: The head orthopaedic team physicians for all 32 NFL teams were asked to complete a survey containing questions regarding experience as team physician, medical coverage of the team, and treatment preferences for some of the most common injuries occurring in football players. Responses from the current survey were compared with responses from the same survey sent to NFL team physicians in 2008. RESULTS: Responses were received from 31 (31/32, 97%) NFL team physicians in 2008 and 29 (29/32, 91%) NFL team physicians between April 2016 and May 2017. The proportion of physicians preferring patellar tendon autograft in anterior cruciate ligament (ACL) reconstruction increased from 87% in 2008 to 97% in 2016 ( P = 0.054). In 2008, 49% of physicians allowed return to contact after ACL reconstruction at 6 months or less as compared with only 14% of physicians in 2016 ( P = 0.033). In 2008, 93% of physicians used Toradol injections prior to a game to help with nagging injuries. Toradol injection utilization decreased to 48% of physicians in 2016 ( P < 0.001). Seventy-nine percent of physicians would administer 5 or more Toradol injections prior to a game in 2008, as compared with 28% of physicians in 2016 ( P < 0.0001). CONCLUSION: Orthopaedic physicians have changed their injury treatment preferences for professional football players. In particular, physicians have become more cautious with allowing players to return to play after ACL reconstruction and with the use of pregame Toradol injections. CLINICAL RELEVANCE: Expert opinions can help guide treatment decisions and lead to better care of all athletes. PMID- 29469659 TI - Grading of oligodendroglial tumors of the brain with apparent diffusion coefficient, magnetic resonance spectroscopy, and dynamic susceptibility contrast imaging. AB - Purpose We explored whether advanced magnetic resonance (MR) imaging techniques could grade oligodendrogliomas. Methods Forty patients (age 9-61 years) with oligodendroglial tumors were selected. There were 23 patients with World Health Organization grade II (group 1) and 17 patients with grade III (group 2) tumors. Apparent diffusion coefficient (ADC) maps were calculated by b values of 0 and 1000 s/mm2. Dynamic susceptibility contrast (DSC) images were obtained during the first pass of a bolus of gadolinium-based contrast. These data were post processed and cerebral blood volume (CBV) maps and permeability (PS) were calculated. MR spectroscopy was acquired after drawing a region of interest on the tumor using two-dimensional chemical shift imaging. Statistical analysis was performed using SPSS software. Results When the rPSmax was combined with the rCBVmax, there was a significant difference between the two groups ( p <= 0.03) with area under the curve of 0.742 (95% CI: 0.412-0.904). rCBV, rADC, choline/creatine, and choline/NAA alone were able to differentiate between the two groups; however, they did not show any statistical difference with p values of <= 0.121, <= 0.722, and <= 0.582, respectively. A CBV PS product threshold of 0.53 provided a sensitivity of 80% and a specificity of 83.3% in detection of grade III tumors. Conclusion Combined rCBVmax and rPSmax can be utilized to grade oligodendrogliomas. ADC values, relative cerebral blood volume (rCBV), and MR spectroscopy alone can be utilized to differentiate between the two groups of oligodendrogliomas but without statistical significance. PMID- 29469666 TI - The DSM-5 Trait Measure in a Psychiatric Sample of Late Adolescents and Emerging Adults: Structure, Reliability, and Validity. AB - The inclusion of a dimensional trait model of personality pathology in DSM-5 creates new opportunities for research on developmental antecedents of personality pathology. The traits of this model can be measured with the Personality Inventory for DSM-5 (PID-5), initially developed for adults, but also demonstrating validity in adolescents. The present study adds to the growing body of literature on the psychometrics of the PID-5, by examining its structure, validity, and reliability in 187 psychiatric-referred late adolescents and emerging adults. PID-5, Big Five Inventory, and Kidscreen self-reports were provided, and 88 non-clinical matched controls completed the PID-5. Results confirm the PID-5's five-factor structure, indicate adequate psychometric properties, and underscore the construct and criterion validity, showing meaningful associations with adaptive traits and quality of life. Results are discussed in terms of the PID-5's applicability in vulnerable populations who are going through important developmental transition phases, such as the step towards early adulthood. PMID- 29469667 TI - 10-Year Outcome of Suicidal Behavior in Borderline Personality Disorder. AB - Prospective predictors of suicide attempts were assessed in 118 subjects with borderline personality disorder (BPD) after 10 or more years of follow-up. Mean (SD) time to follow-up was 14.4 (4.7) years. Subjects were predominately female (78.8%), Caucasian (81.4%), and of lower socioeconomic status. Initial recruitment was evenly balanced between inpatient, outpatient, and non-patient (community) sources. In the 10-year interval, 55 subjects (46.6%) attempted suicide. Compared to baseline, suicidal ideation, number of attempts, and non suicidal self-injury diminished markedly. Core symptoms of BPD, substance abuse, and alcohol use disorders decreased significantly; however, major depressive disorder (MDD) remained constant at 50%. Forty-four percent of subjects had poor psychosocial, vocational, and economic outcomes. Psychosocial outcome was independent of suicide history and any treatment. Increased risk was associated with interval hospitalization prior to any attempt (illness severity), as well as poor social, vocational, and psychosocial functioning at baseline.

AB - Type 2 diabetes is almost three times more prevalent in the indigenous people of New Zealand (Maori) than non-Maori. Despite the high rate of diabetes there is a low level of diabetes knowledge and awareness in the Maori community. Several studies of Maori health identify a need for new health communication approaches to diabetes prevention in order to reduce the gap between Maori and non-Maori disease rates. We applied a Community-Based Participatory Research (CBPR) framework and behavioral theory to create a culturally appropriate documentary for Maori at risk for type 2 diabetes. We discuss how we utilized Bandura's social cognitive theory to provide a culturally sensitive theoretical basis for behavior change messaging. We outline why social cognitive theory was a culturally appropriate foundation and describe the role of the community in shaping the documentary messaging. A culture-centered approach utilizing participatory methodologies and culturally sensitive behavioral change theory might serve as a model for creating health communication resources in collaboration with other indigenous communities. PMID- 29469668 TI - Review of de novo cerebral arteriovenous malformation: haemorrhage risk, treatment approaches and outcomes. AB - Objective A small number of patients has been reported to develop a completely new or de novo arteriovenous malformation (AVM) after brain surgery, haemorrhage, head trauma or ischaemic stroke. The natural history of these lesions is unknown. In this review, both ruptured and unruptured de novo AVMs and their treatments were reviewed. Methods Published literature in the PubMed database citing 'de novo cerebral arteriovenous malformation' was reviewed. Additional studies were identified through reference searches in each reviewed article. A review was performed using all published cases, the treatment approaches and outcomes. Results A total of 38 patients, including 37 de novo AVMs reported from 1988 to 17 November 2017 and our one patient, was collected. The age at AVM diagnosis was 5-73 years (mean +/- SD, 27.6 +/- 20.5 years). The duration time, from negative examination to AVM diagnosis, was 2 months to 25 years (mean +/- SD, 6.6 +/- 4.9 years). The presentation of de novo AVM was headaches in three (7.9%) patients, bleedings in 12 (31.6%), incidental in 14 (36.8%) and seizure in nine (23.7%). The estimated risk of haemorrhage was 4.8% per year. Seventeen (44.7%) patients were treated with surgical resection, 10 (26.3%) were conservatively observed, nine (23.7%) were treated with radiosurgery and two (5.3%) were endovascularly embolised. The morbidity and mortality were reported as 5.3% and 7.9%, respectively. Conclusion Post-natal de novo AVMs have been reported. Their annual haemorrhage risk is 4.8%. Most of them are treated by surgical resection and are associated with morbidity and mortality. PMID- 29469670 TI - Role of miRNAs in treatment response and toxicity of childhood acute lymphoblastic leukemia. AB - Childhood acute lymphoblastic leukemia survival rates have increased remarkably during last decades due, in part, to intensive treatment protocols. However, therapy resistance and toxicity are still two important barriers to survival. In this context, pharmacoepigenetics arises as a tool to identify new predictive markers, required to guide clinicians on risk stratification and dose individualization. The present study reviews current evidence about miRNA implication on childhood acute lymphoblastic leukemia therapy resistance and toxicity. A total of 12 studies analyzing differential miRNA expression in relation to drug resistance and six studies exploring the association between miRNAs-related SNPs and drug-induced toxicities were identified. We pointed out to miR-125b together with miR-99a and/or miR-100 overexpression as markers of vincristine resistance and rs2114358 in mir-1206 as mucositis marker as the most promising results. PMID- 29469671 TI - Patient perspectives following pharmacogenomics results disclosure in an integrated health system. AB - AIM: To assess patient perceptions and utilization of pharmacogenomics (PGx) testing in an integrated community health system. METHODS: Fifty-seven patients completed an online survey assessing their experiences with PGx testing offered through two methods: a designated PGx clinic or direct access in-home testing. RESULTS: The majority of participants perceived PGx testing as helpful in their healthcare and reported understanding their results. Some had concerns about privacy and discrimination; most lacked familiarity with the Genetic Information Nondiscrimination Act. There were no significant differences in views between participants tested through either model. CONCLUSION: Participants reported value in both methods of PGx testing. Patient experiences, understanding and result utilization will play an important role in informing future development and implementation of PGx programs. PMID- 29469672 TI - VA Staff Perceptions of Barriers and Facilitators to Home-and Community-Based Placement Post-Hospital Discharge. AB - This study identifies factors U.S. Department of Veterans Affairs (VA) staff perceived to promote or impede home- and community-based services (HCBS) placement post-hospital discharge among Veterans cared for within the VA. Data derive from 35 semi-structured interviews with staff from 12 VA medical centers from around the country. VA staff reported that Veteran's care needs and social and financial resources influence HCBS placement. They also reported prerequisites for successful placement, including housing, unpaid informal care, and non-VA services funded privately and by public programs such as Medicaid and the Older Americans Act. Lack of staffing and failure to offer the specific types of services needed limit referral to and use of HCBS. Budgetary imperatives influence the relative availability of HCBS across VA medical centers. Findings highlight patient-, provider-, and system-level constraints that impede successful placement at home and in the community of Veterans in need of long term services and supports after hospitalization.

AB - With the development of positive psychology, protective factors have received increased attention as buffers against suicidal ideation and attempts and against the risk factors for suicide (e.g., depressive symptoms). Empirical evidence suggests that one of the protective factors associated with depression and suicide is forgiveness. Although previous studies have demonstrated a negative association between forgiveness and risk of suicide, studies on gender differences in adolescents are still scarce. Thus, the authors assessed the moderating role of gender in a sample of adolescents. The participants were 572 adolescents (50.9% boys; M age = 15.49 years, SD = 1.09 years) from secondary school centers. The results revealed that forgiveness moderated the relationship between depression and suicidal ideation for boys but not for girls. Specifically, for boys the relationship between depression and suicidal thoughts and behaviors weakened as levels of forgiveness increased. These findings suggest therapeutic applications to reduce the likelihood of suicide in the group of adolescent boys with higher scores on depression and lower levels of forgiveness. The study results are discussed in terms of the need to use gender perspectives in positive psychology intervention programs.

AB - This article explores how local politicians and care unit managers in Swedish eldercare experience and respond to state supervision (SSV). Twelve politicians and twelve managers in 15 previously inspected municipalities were interviewed about their experiences of and reactions to SSV in relation to their views of care quality and routines in eldercare practice. The findings indicate that local managers and political chairs perceived SSV in eldercare positively at a superficial level but were critical of and disappointed with specific aspects of it. In terms of (a) governance, chairs and managers said SSV strengthened implementation of national policies via local actors, but they were critical of SSV's narrow focus on control and flaws in eldercare practice. With regard to (b) accountability, SSV was seen as limited to accountability for finances and systemic performance, and regarding (c) organizational development, SSV was seen as limited to improving routines and compliance with legislation, while local definitions of quality are broader than that. In general, local actors regarded SSV as improving administrative aspects and routines in practice but ignoring the relational content of eldercare quality. PMID- 29469675 TI - Lessons from the Past: Some Histories of Alpha-1 Antitrypsin Deficiency Before Its Discovery. AB - A1AT deficiency- a genetically inherited autosomal codominant disease with more than 120 identified alleles- was first identified by Laurell and Eriksson in 1963. The most common hereditary disorder in adults, A1AT causes an increased risk of developing pulmonary emphysema and liver disease. In A1AT patients, lung disease generally presents at a younger age than "usual" chronic obstructive pulmonary disease (COPD) and it may be misdiagnosed as asthma. Because A1AT deficiency patients can show the same clinical features as non-deficient COPD (including increased evidence of bronchiectasis, frequent exacerbations, impaired health status and a degree of reversibility of airflow obstruction), the World Health Organization recommend to test every patient with a diagnosis of COPD or adult-onset asthma for A1AT deficiency. Despite these recommendations, the epidemiology of A1AT deficiency remains uncertain. Although recently discovered A1AT deficiency has affected human populations since antiquity. By using scientific data and recently studied skeletons and historical cases, we show that it is now possible to reconstruct the natural history of pathological processes, whether due to genetic, infectious or environmental factors. We believe that the evolution of disease in patients and research to elucidate the relationship between social science and environmental are pertinent contemporaneous subjects. PMID- 29469676 TI - The Glittre-ADL Test Cut-Off Point to Discriminate Abnormal Functional Capacity in Patients with COPD. AB - The study objective was to determine a cut-off point for the Glittre activities of daily living (ADL)test (TGlittre) to discriminate patients with normal and abnormal functional capacity. Fifty-nine patients with moderate to very severe COPD (45 males; 65 +/- 8.84 years; BMI: 26 +/- 4.78 kg/m2; FEV1: 35.3 +/- 13.4% pred) were evaluated for spirometry, TGlittre, 6-minute walk test (6 MWT), physical ADL, modified Medical Research Council scale (mMRC), BODE index, Saint George's Respiratory Questionnaire (SGRQ), and COPD Assessment Test (CAT). The receiver operating characteristic (ROC) curve was used to determine the cut-off point for TGlittre in order to discriminate patients with 6 MWT < 82% pred. The ROC curve indicated a cut-off point of 3.5 minutes for the TGlittre (sensitivity = 92%, specificity = 83%, and area under the ROC curve = 0.95 [95% CI: 0.89 0.99]). Patients with abnormal functional capacity had higher mMRC (median difference 1 point), CAT (mean difference: 4.5 points), SGRQ (mean difference: 12.1 points), and BODE (1.37 points) scores, longer time of physical activity <1.5 metabolic equivalent of task (mean difference: 47.9 minutes) and in sitting position (mean difference: 59.4 minutes) and smaller number of steps (mean difference: 1,549 minutes); p < 0.05 for all. In conclusion, the cut-off point of 3.5 minutes in the TGlittre is sensitive and specific to distinguish COPD patients with abnormal and normal functional capacity. PMID- 29469677 TI - Spirometric Criteria for Chronic Obstructive Pulmonary Disease in Clinical Trials of Pharmacotherapy. AB - Clinical trials of pharmacotherapy in chronic obstructive pulmonary disease (COPD) often include older persons with moderate-to-severe airflow-obstruction, as defined by the Global Initiative for chronic Obstructive Lung Disease (GOLD). In this context, spirometric airflow-obstruction establishes COPD. Because GOLD misidentifies COPD and its severity in older persons, we set out to apply more age-appropriate spirometric criteria from the Global Lung function Initiative (GLI) in a prior clinical trial of COPD pharmacotherapy, specifically the Towards a Revolution in COPD Health (TORCH) trial - N = 6,112, mean age 65 years. In the TORCH trial, which enrolled GOLD-defined moderate COPD (26.2%, n = 1,200) and GOLD-defined severe COPD (73.8%, n = 4,511), the GLI reclassification yielded a higher frequency of severe COPD (89.6%, n = 5,474), the inclusion of restrictive pattern (6.9%, n = 420) and, in turn, a very low frequency of moderate COPD (3.5%, n = 212). These GLI reclassification results suggest that GOLD-based enrollment criteria for the TORCH trial may have assembled a cohort that was: 1) less likely to respond to COPD pharmacotherapy, given the greater representation of severe COPD, very minor representation of moderate COPD, and inclusion of a non-obstructive spirometric impairment (restrictive-pattern); and 2) more likely to have medication-related adverse events, given the inappropriate use of COPD pharmacotherapy in misidentified COPD (restrictive-pattern). We therefore propose that future clinical trials of COPD pharmacotherapy should consider GLI criteria for defining COPD, including a greater representation of GLI-defined moderate COPD.

A piece of wood injured his orbital and supraorbital regions while working at a furniture factory 10 days prior to our hospital admission. It was learned that the patient was discharged following the primary would closure procedure. Subsequent to the craniofacial computed tomography, primary wound closure was performed in the emergency room of previous hospital. In our clinic, a skin suturing on the nasal side of the right eyebrow was inspected and a foreign body (FB) was palpated on the superonasal contiguity of the patients' right globe. A hyperdense FB measuring 30 * 10 * 5 mm in size with smooth margins on superonasal contour of the globe was detected. Superonasal orbitotomy was performed and the FB was completely removed. Finally, visual acuity was 20/20 and a mild residual ptosis was observed. PMID- 29469679 TI - Gabrielle Levy and the Roussy-Levy syndrome. AB - In 1934, Gabrielle Levy died at the age of 48. She became well known for an article she published on a hereditary polyneuropathy in cooperation with Gustav Roussy, resulting in the eponym Roussy-Levy syndrome. Not much is known about this extraordinary neurologist/neuropathologist. Her family declared that she died from the disease she was studying. She was a pupil of Pierre Marie, with whom she worked at the Salpetriere in Paris and wrote on war neurology. In cooperation with Marie, she published a number of articles on postencephalitic syndromes, which also became the subject of her 1922 thesis. Three years later, she became associate physician at the Paul-Brousse Hospital in Paris, where the study of brain tumors became one of the subjects of her scientific work. Remarkably, Levy was first author in a few of her many articles, although Roussy confirmed that she often initiated the study and even wrote the main part. In this article her career is considered in the context of the struggle of women physicians to improve their position during the early-twentieth century. She probably died from a brain tumor or a postencephalitic syndrome. PMID- 29469680 TI - Cognitive Impairment and Social Security's Representative Payee Program. AB - Social Security's Representative Payee Program faces a difficult balance with respect to dementia: Many people living with dementia can conduct their finances without a payee if they have help from informal caregivers, but those without help are at risk. To date, it has been unclear what share of retirees with dementia use a payee, what share has help potentially available from another source, and what share has no observed means of assistance. This study finds that while fewer than 10% of retirees with dementia use a payee, only about 8% have no observed means of help. PMID- 29469681 TI - Lack of Association Between Type 2 Diabetes and the 3673G / A and 9041G / A Gene Variants of Vitamin K Epoxide Reductase Complex Subunit 1 (VKORC1). AB - The vitamin K epoxide reductase complex subunit 1 (VKORC1) gene is expressed in many tissue types, and encodes the VKORC1 protein, which is a key enzyme in the vitamin K cycle. Although researchers have focused on the effects of vitamin K on glucose metabolism, and on its role in the development of type 2 diabetes (T2DM), no consensus has yet been reached. Therefore, here we aimed to investigate the association between VKORC1 variants and the risk of T2DM. The 3673G / A (rs9923231) and 9041G / A (rs7294) VKORC1 variants were investigated by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in 100 control individuals and 100 patients with T2DM. The genomic regions were amplified by PCR; amplicons were digested using the AciI and NciI enzymes and visualized by agarose gel electrophoresis. The genotype frequencies of the 3673G / A variants were GG (22%), GA (56%), and AA (22%) in the control group and GG (19%), GA (52%), and AA (29%) in patients with T2DM (p > 0.05). The genotype frequencies of the 9041G / A variants were GG (37%), GA (53%), and AA (10%) in the control group and GG (46%), GA (45%), and AA (9%) in patients with T2DM (p > 0.05). In conclusion, we found no significant correlation between the control group and patients with T2DM, with regard to the different genetic models of the 3673G / A and 9041G / A variants. These data suggest that these VKORC1 gene variants may not be linked to T2DM. PMID- 29469682 TI - Vitamin D Supplementation in Adults with Vitamin D Deficiency and Its Effect on Metabolic Syndrome - A Randomized Controlled Study. AB - BACKGROUND: Inverse relationship between metabolic syndrome (MetS) and 25 hydroxyvitamin D (25(OH) D) levels is controversial. Hypovitaminosis-D has long been suspected as a risk factor for glucose intolerance. AIM: A randomized double blind placebo controlled study to evaluate effects of vitamin D supplementation on insulin resistance in subjects with hypovitaminosis-D and MetS. MATERIALS AND METHODS: Subjects were randomized to receive either oral 25(OH) D3 supplement (60000 (IU) per week for 8 weeks followed by 60,000 IU monthly for 4 months) or a placebo for six months. The parameters measured were blood pressure, vitamin D, fasting blood sugar (FBS), insulin, homeostasis model assessment (HOMA), quantitative insulin sensitivity check index (QUICKI), body mass index (BMI), and waist circumference (WC). RESULTS: There were no significant changes in parameters of vitamin-D group compared to placebo group except serum vitamin-D was significantly increased in vitamin-D group (p < 0.0001). In vitamin-D group, mean WC at baseline was 95.9 +/- 6.66, which significantly changed to 94.6 +/- 7.47 (p = 0.001). Mean BMI at baseline was 29.1 +/- 4.06 which significantly changed to 28.5 +/- 4.16 (p = 0.001). The mean vitamin-D concentration at baseline was 15.4 +/- 9.03 which significantly (p < .0001) increased to 26.1 +/- 11.8. In placebo group mean insulin levels was 10.7 +/- 4.81IU / L which increased significantly (p = 0.03) to 15.4 +/- 14.0. Mean QUICKI at baseline was 0.34 +/- 0.03 which decreased significantly (p = 0.02) to 0.32 +/- 0.03. CONCLUSION: In this study the relationship between vitamin D supplementation and MetS or IR was not established. Whether achieving vitamin D sufficiency in large population-based trials with a longer duration would produce more favorable results needs to be assessed. PMID- 29469683 TI - Positive Association Between Serum 25-Hydroxy-Vitamin D and Liver Enzymes Levels in Healthy Individuals: A Population-Based Study from Iran. AB - OBJECTIVE: The relationship between serum 25-hydroxy-vitamin D and within normal range liver enzymes in a population-based study in the northwest of Iran was investigated. METHOD: This cross-sectional study was comprised of 700 apparently healthy Iranian adults (287 men & 413 women) who participated in the major lifestyle promotion project (LPP) conducted in East Azarbaijan-Iran in 2015. The ultraviolet method and chemiluminescent immunoassay technology were respectively used for determination of the serum levels of liver enzymes (alanine aminotransferase (ALT) and aspartate aminotransferase (AST)) and 25-hydroxy vitamin D. The one-way ANOVA and the linear regression analysis were used for statistical analysis. RESULTS: There were not significant differences in mean ALT and AST levels regarding different serum 25-hydroxy- vitamin D status. In the unadjusted model, serum 25-hydroxy-vitamin D was significantly associated with ALT (p = 0.008). The participants in the fourth quartile of 25-hydroxy-vitamin D had significantly higher level of ALT compared with participants in the first quartile (p = 0.002). After adjustment for age, sex, BMI, waist circumference, fasting blood glucose, lipid profile, and dietary vitamin D, this association remained significant. For AST, in the unadjusted model, the association between serum 25-hydroxy-vitamin D and AST was marginally significant (p = 0.08). The participants in the third quartile of 25-hydroxy-vitamin D had significantly higher levels of AST compared with participants in the first quartile (p = 0.01). CONCLUSION: According to results, there was a positive association between 25 hydroxy-vitamin D and ALT in individuals without liver diseases. Additional prospective studies were needed to confirm this observation and also elucidate the underlying mechanisms.

AB - Papillomaviridae is a diverse family of circular, double-stranded DNA (dsDNA) viruses that infect a broad range of mammalian, avian and fish hosts. While papillomaviruses have been characterized most extensively in humans, the study of non-human papillomaviruses has contributed greatly to our understanding of their pathogenicity and evolution. Using high-throughput sequencing approaches, we identified 7 novel papillomaviruses from vaginal swabs collected from 81 adult female Weddell seals (Leptonychotes weddellii) in the Ross Sea of Antarctica between 2014-2017. These seven papillomavirus genomes were amplified from seven individual seals, and six of the seven genomes represented novel species with distinct evolutionary lineages. This highlights the diversity of papillomaviruses among the relatively small number of Weddell seal samples tested. Viruses associated with large vertebrates are poorly studied in Antarctica, and this study adds information about papillomaviruses associated with Weddell seals and contributes to our understanding of the evolutionary history of papillomaviruses. PMID- 29469688 TI - Bizionia berychis sp. nov., isolated from intestinal tract of a splendid alfonsino (Beryx splendens). AB - A Gram-stain-negative, non-motile, aerobic and rod-shaped bacterial strain, designated RA3-3-1T, was isolated from splendid alfonsino (Beryxsplendens) collected from the North Pacific Ocean. Strain RA3-3-1T grew optimally at 25 degrees C, at pH 7.0-8.0 and in the presence of 1.0-3.0 % (w/v) NaCl. The neighbour-joining phylogenetic tree based on 16S rRNA gene sequences revealed that strain RA3-3-1T belonged to the genus Bizionia, clustering with the type strain of Bizionia fulviae. Strain RA3-3-1T exhibited 16S rRNA gene sequence similarities of 98.7, 97.6 and 97.3 % to the type strains of B. fulviae, Bizionia paragorgiae and Bizionia saleffrena, respectively, and of 95.5-96.4 % to the type strains of the other Bizionia species. Strain RA3-3-1T contained MK-6 as the predominant menaquinone and anteiso-C15 : 0, iso-C16 : 0 3-OH, summed feature 3 (C16 : 1omega7c and/or C16 : 1omega6c), iso-C17 : 0 3-OH, iso-C15 : 0 and C17 : 0 2-OH as the major fatty acids. The major polar lipids detected in strain RA3-3-1T were phosphatidylethanolamine, one unidentified lipid and one unidentified aminolipid. The DNA G+C content of strain RA3-3-1T was 34.1 mol% and its DNA-DNA relatedness values with the type strains of B. fulviae, B. paragorgiae and B. saleffrena were 12-29 %. Differential phenotypic properties, together with its phylogenetic and genetic distinctiveness, revealed that strain RA3-3-1T is separate from recognized species of the genus Bizionia. On the basis of the data presented, strain RA3-3-1T is considered to represent a novel species of the genus Bizionia, for which the name Bizionia berychis sp. nov. is proposed. The type strain is RA3-3-1T (=KCTC 62140T=NBRC 113024T). PMID- 29469689 TI - Genomic and structural features of the yellow fever virus from the 2016-2017 Brazilian outbreak. AB - Southeastern Brazil has been suffering a rapid expansion of a severe sylvatic yellow fever virus (YFV) outbreak since late 2016, which has reached one of the most populated zones in Brazil and South America, heretofore a yellow fever-free zone for more than 70 years. In the current study, we describe the complete genome of 12 YFV samples from mosquitoes, humans and non-human primates from the Brazilian 2017 epidemic. All of the YFV sequences belong to the modern lineage (sub-lineage 1E) of South American genotype I, having been circulating for several months prior to the December 2016 detection. Our data confirm that viral strains associated with the most severe YF epidemic in South America in the last 70 years display unique amino acid substitutions that are mainly located in highly conserved positions in non-structural proteins. Our data also corroborate that YFV has spread southward into Rio de Janeiro state following two main sylvatic dispersion routes that converged at the border of the great metropolitan area comprising nearly 12 million unvaccinated inhabitants. Our original results can help public health authorities to guide the surveillance, prophylaxis and control measures required to face such a severe epidemiological problem. Finally, it will also inspire other workers to further investigate the epidemiological and biological significance of the amino acid polymorphisms detected in the Brazilian 2017 YFV strains. PMID- 29469690 TI - Non-canonical Escherichia coli transcripts lacking a Shine-Dalgarno motif have very different translational efficiencies and do not form a coherent group. AB - Translation initiation in 50-70 % of transcripts in Escherichia coli requires base pairing between the Shine-Dalgarno (SD) motif in the mRNA and the anti-SD motif at the 3' end of the 16S rRNA. However, 30-50 % of E. coli transcripts are non-canonical and are not preceded by an SD motif. The 5' ends of 44 E. coli transcripts were determined, all of which contained a 5'-UTR (no leaderless transcripts), but only a minority contained an SD motif. The 5'-UTR lengths were compared with those listed in RegulonDB and reported in previous publications, and the identities and differences were obtained in all possible combinations. We aimed to quantify the translational efficiencies of non-canonical 5'-UTRs using GusA reporter gene assays and Northern blot analyses. Ten non-canonical 5'-UTRs and two control 5'-UTRs with an SD motif were cloned upstream of the gusA gene. The translational efficiencies were quantified under five different conditions (different growth rates via two different temperatures and two different carbon sources, and heat shock). The translational efficiencies of the non-canonical 5' UTRs varied widely, from 5 to 384 % of the positive control. In addition, the non canonical transcripts did not exhibit a common regulatory pattern with changing environmental parameters. No correlation could be observed between the translational efficiencies of the non-canonical 5'-UTRs and their lengths, sequences, GC content, or predicted secondary structures. The introduction of an SD motif enhanced the translational efficiency of a poorly translated non canonical transcript, while the efficiency of a well-translated non-canonical transcript remained unchanged. Taken together, the mechanisms of translation initiation at non-canonical transcripts in E. coli still need to be elucidated. PMID- 29469691 TI - Paracoccus alimentarius sp. nov., isolated from a Korean foodstuff, salted pollack. AB - A Gram-stain-negative, aerobic, non-motile and coccoid or ovoid bacterial strain, designated LB2T, was isolated from a Korean foodstuff, salted pollack. Strain LB2T grew optimally at 25-30 degrees C, at pH 7.0-8.0 and in the presence of 0 2.0 % (w/v) NaCl. Phylogenetic trees based on 16S rRNA gene sequences showed that strain LB2T belonged to the genus Paracoccus, coherently clustering with the type strain of Paracoccus sulfuroxidans. Strain LB2T exhibited 16S rRNA gene sequence similarity values of 98.0 and 97.0 % to the type strains of P. sulfuroxidans and Paracoccus halophilus, respectively, and of less than 96.9 % to the type strains of other Paracoccus species. Strain LB2T contained Q-10 as the predominant ubiquinone. Major fatty acids of strain LB2T were cyclo C19 : 0omega8c, C18 : 1omega7c and C16 : 0 (when grown on MA) or C18 : 1omega7c and C16 : 0 (on TSA). The major polar lipids detected in strain LB2T were phosphatidylcholine, phosphatidylglycerol, diphosphatidylglycerol, one unidentified aminolipid and one unidentified glycolipid. The DNA G+C content of strain LB2T was 61.4 mol% and its DNA-DNA relatedness values with the type strains of P. sulfuroxidans and P. halophilus were 26 and 18 %, respectively. Differential phenotypic properties, together with its phylogenetic and genetic distinctiveness, revealed that strain LB2T is separated from recognized Paracoccus species. On the basis of the data presented, strain LB2T is considered to represent a novel species of the genus Paracoccus, for which the name Paracoccus alimentarius sp. nov. is proposed. The type strain is LB2T (=KCTC 62138T=NBRC 113023T). PMID- 29469692 TI - The role of interleukin-17 in the pathogenesis of hidradenitis suppurativa. AB - Hidradenitis suppurativa is a chronic inflammatory skin condition affecting primarily the axillary, perianal, and inguinal areas. Patients with hidradenitis suppurativa present with occlusion and subsequent rupture of follicular ducts, profound abscesses, fistulae, odorous discharge, fibrosis, and scar formation, causing significant morbidity. Knowledge of the pathogenesis of hidradenitis suppurativa is limited and treatment with antimicrobial drugs, immunosuppressants, and surgical procedures have shown varying results. The pathogenic role of the interleukin-17 cytokine family in chronic inflammatory skin conditions has been described. Interleukin-17A and interleukin-17F have similar properties and induce the production of cytokines, chemokines, antimicrobial peptides, and metalloproteinases, all of which take part in the inflammatory response. The efficacy of anti-interleukin-17A therapy in psoriasis has also been proven and anti- interleukin-17A drugs are already in use for this condition. There is currently no consensus on the role of interleukin-17 in the pathogenesis of hidradenitis suppurativa. Studies have demonstrated increased interleukin-17 mRNA expression in lesional hidradenitis suppurativa skin, whereas the protein concentrations of interleukin-17 were found to be normal compared to healthy control skin in one other study. A phase II clinical trial on anti- interleukin-17 therapy in hidradenitis suppurativa is ongoing. PMID- 29469693 TI - Dermatology on Reddit: elucidating trends in dermatologic communications on the world wide web. AB - Platforms of social media, including the website Reddit, have become increasingly popular sites for users to communicate medical information. A study investigating dermatology content on Reddit has not been performed in the current literature. The purpose of this study is to enumerate the dermatology subreddits, quantify subscribers, and characterize posts to estimate the presence of dermatology related content on Reddit. A Reddit search of the fourteen most common skin diseases globally was performed. Additionally, the terms "dermatology", and "skin" were searched in order to identify more subreddits relevant to the field. Dermatology-related subreddits that had >=1000 subscribers were evaluated for content and categorized for analysis. We identified 38 subreddits related to dermatology with subscriber numbers ranging from 52 to 209,973. For 17 of the 38 subreddits that were further analyzed, most posts fell under the category of "seeking health/cosmetic advice." Reddit serves as a communication stage for individuals to discuss, engage, and connect on dermatologic topics. Furthermore, the platform offers an opportunity for medical professionals to distribute evidence-based information concerning dermatologic conditions. PMID- 29469694 TI - Dermatology on Snapchat. AB - Launched in 2011, Snapchat is one of the newest social media platforms with over 158 million active daily users. This study investigated the presence of dermatology-related content on Snapchat. We searched for Snapchat accounts for the top ten most popular dermatology journals, professional dermatological organizations, and dermatology-related patient advocate groups on social media. None of the above-mentioned entities were found on Snapchat. Plastic surgeons were found to primarily utilize the application, although one prominent dermatologist was also found. It was theorized that the brevity of the "snaps" was a contributing factor for dermatological organizations to not use the application. However, Snapchat in the right practice setting may be useful for dermatologists, not only to educate followers, but also as a marketing tool to Millennials. PMID- 29469695 TI - Cutaneous Balamuthia mandrillaris infection as a precursor to Balamuthia amoebic encephalitis (BAE) in a healthy 84-year-old Californian. AB - Soil and freshwater-dwelling amoebae may opportunistically infect the skin and evoke a granulomatous dermatitis that camouflages their underlying morphology. Amoebic infestations are incredibly rare in the U.S., predominantly occurring in the young, elderly, and immunocompromised. Sadly, because diagnosis is difficult and unsuspected, most cases are diagnosed at autopsy. The following case is of a healthy 84-year-old man with a non-healing nodulo-ulcerative cutaneous lesion on his left forearm that appeared following a gardening injury. Lesional punch biopsies repeatedly showed non-specific granulomatous inflammation with no pathogens evident histologically or by culture. Histopathologic diagnosis was made five months after initial presentation via identification of amoebic trophozoite forms in tissue from a large excisional specimen. Anti-amoebic therapy was initiated immediately. The patient experienced mental status changes three days following lesion excision, with evidence of a cystic mass in the left medial parieto-occipital lobe by CT. Both intraoperative brain biopsies and cutaneous tissue samples tested positive for Balamuthia mandrillaris by indirect immunofluorescent antibody assay performed at the Centers for Disease Control. The patient achieved a full recovery on a triple antibiotic regimen. Clinical suspicion and thorough histopathologic analysis may determine the difference between survival and death for a patient presenting with a treatment-refractory localized granulomatous lesion. PMID- 29469696 TI - Adalimumab-related alopecia in a patient affected by psoriasis. AB - Alopecia induced by biological therapy is a rare side effect of this type of drugs. A total of 23 patients of psoriasiform eruptions with severe scalp involvement that induced alopecia during anti-tumor necrosis factor (anti-TNF) treatment of non-dermatological conditions have been previously reported. We present a 50-year-old man affected by plaque psoriasis that developed psoriasiform patches with alopecia over his scalp 10 months after initiating treatment with adalimumab. Punch biopsy of the alopecic area on the scalp revealed psoriasiform epidermal changes and alopecia areata-like dermal changes. Along with these findings, there was a dermal inflammatory infiltrate made up of eosinophils and plasma cells. In conclusion, scalp psoriasiform lesions with alopecia in patients treated with anti-TNF agents have been rarely reported. We describe a patient with anti-TNF therapy-related alopecia affected by psoriasis. Our patient has a peculiar histology with features of psoriasis and alopecia areata in addition to eosinophils and plasma cells. This entity may respond to topical treatment. However in patients of severe scalp involvement anti-TNF suspension should be considered. PMID- 29469697 TI - Generalized bullous fixed drug eruption imitating toxic epidermal necrolysis: a case report and literature review. AB - Fixed drug eruption (FDE) is defined as sharply demarcated erythematous patches or plaques that occur secondary to systemic exposure to a causative medication. Eruptions are deemed "fixed" because upon repeated exposure they recur at previously affected sites. Generalized bullous fixed drug eruption (GBFDE) is a rare FDE variant occurring in patients with a previous history of FDE. Given the extensive cutaneous involvement and the frequent mucosal ulcerations associated with GBFDE, it is challenging to discern these lesions from Steven-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). The presence of significantly elevated lesional and serum granulysin in SJS/TEN is an important discriminating factor because granulysin levels remain significantly lower in GBFDE. The implementation of an immunochromatographic test for rapid detection of elevated granulysin levels could therefore facilitate the early diagnosis of SJS/TEN. We report a case of GBFDE to elucidate the characteristic differences in clinical presentation, histopathology, and immunohistochemistry that can facilitate diagnosis. PMID- 29469698 TI - Acquired bullous acrodermatitis enteropathica as a histologic mimic of pemphigus foliaceus in a patient on parenteral nutrition. AB - Acquired zinc deficiency can develop as a consequence of poor nutritional intake or from dependence on total parenteral nutrition. Acquired zinc deficiency dermatitis classically manifests with erosions and scaly plaques in a periorificial and acral distribution. We present a case of a woman on parenteral nutrition who presented with bullous acrodermatitis mimicking pemphigus foliaceus histopathologically. This case highlights clinical and histopathologic variants of zinc deficiency that may lead to a delay in diagnosis. PMID- 29469699 TI - Mycophenolate mofetil as a successful therapy for idiopathic granulomatous mastitis. AB - Idiopathic granulomatous mastitis (IGM) is a benign chronic inflammatory breast disease of unknown etiology. No consensus exists as to the best therapeutic approach, though treatment choices include antibiotics, drainage, surgical excision, steroids, methotrexate, and observation. Herein we report a case of idiopathic granulomatous mastitis that was refractory to methotrexate and intralesional and systemic steroids but responded well to mycophenolate mofetil 1500mg twice daily. To our knowledge, this is the first report of the effective use of mycophenolate mofetil in idiopathic granulomatous mastitis. PMID- 29469700 TI - Crystalline folliculitis revealed by non-aqueous staining technique. AB - Necrotizing infundibular crystalline folliculitis (NICF) is a rare superficial folliculitis characterized by expansive deposits of birefringent crystallized lipid. We report a case of NICF in a transplant patient presenting with folliculocentric acneiform papules across the lateral face and neck. Biopsy demonstrated intrafollicular crystalline deposits within an intact epidermis. Diagnostic crystals were identified using a non-aqueous histologic technique involving thick unstained sections. To our knowledge, this is the first report of NICF in a transplant patient. Our case suggests NICF is a follicular disorder and highlights a technique that may prevent loss of birefringent crystals and assist in facilitating accurate diagnosis. PMID- 29469701 TI - Disseminated cutaneous sporotrichosis presenting as a necrotic facial mass: Case and review. AB - Sporotrichosis is a subcutaneous mycotic infection caused by Sporothrix schenckii, a group of common saprophytes of soil, plants, and organic debris. Disseminated forms may be seen in the setting of immunosuppression and are typically treated initially with intravenous lipidized amphotericin B. We report an unusual case of a 65-year-old woman who developed disseminated cutaneous sporotrichosis with extensive facial involvement in the absence of a known primary inoculation. Her cutaneous lesions completely resolved after treatment with intravenous posaconazole without amphotericin B. PMID- 29469702 TI - Infantile bullous pemphigoid with "string of pearls sign". AB - Bullous pemphigoid (BP) is an immune mediated bullous disease that is manifested by urticarial plaques with superimposed subepidermal blisters and significant pruritus. It is generally found in the elderly, but is rare in the pediatric population. A 5-month-old girl previously diagnosed with hand-foot-mouth disease was examined in our dermatology department owing to vesicles and bullae, initially located to the hands and feet, which progressed with new lesions. Tense vesicles and bullae distributed in an annular string of pearls pattern on the abdomen and facial and cervical regions were noted. Histologic and immunologic findings were consistent with the diagnosis of infantile BP. Disease control was obtained with oral prednisolone and dapsone; the patient was still in clinical remission 6 months after treatment cessation. The differential diagnosis of the clinical presentation of the lesions in our patient is of note, given that this blistering pattern is frequently reported in association with linear IgA bullous dermatosis. PMID- 29469703 TI - A pediatric case of unusual melanocytic proliferation of the nail. AB - Pigmentation of the nail plate, or melanonychia, is typically a benign condition caused by melanocyte activation. Although rare, melanonychia may be the initial presentation of melanoma, thus all cases require an in-depth examination. Evaluation in pediatric patients can prove especially difficult as benign cases have a higher prevalence of atypia compared to adults. Lack of specific treatment guidelines in the pediatric population can make diagnosis and treatment challenging. We report a pediatric patient with melanonychia with atypical features that required significant evaluations and collaboration to ultimately reach a treatment plan. PMID- 29469704 TI - Congenital juvenile xanthogranuloma with ulceration: a pediatric case report. AB - Congenital juvenile xanthogranuloma (JXG) is an uncommon diagnosis and even more rarely presents with ulceration. We report such a case in a two-week-old girl. Biopsy was performed to rule out any concerning entities. Adequate treatment was provided with topical petrolatum and occasional miconozole or zinc oxide; the mass spontaneously regressed. Because congenital JXG has an excellent prognosis, insight into unique presentations such as this may provide useful information and avoid unnecessary surgical interventions. PMID- 29469705 TI - Herpes zoster ophthalmicus with associated vasculopathy causing stroke. AB - Varicella zoster virus (VZV) is an exclusively human, double-stranded DNA virus. Primary infection causes varicella (chickenpox); later the virus becomes dormant in the dorsal root, cranial nerve, and autonomic ganglia along the entire span of the nervous system, retaining the capacity to reactivate and cause a variety of dermal and neurological complications. Recently there has been increasing recognition, both clinically and epidemiologically, of the relationship between VZV and subsequent strokes. Herein, we describe a case of a previously healthy individual with reactivation of VZV causing herpes zoster opthtalmicus along with devastating multifocal vasculopathy. It is crucial for dermatologists to recognize the dermatomal vesicular eruption in this high risk area to aid in prompt diagnosis in an effort to improve clinical prognosis. PMID- 29469706 TI - Alopecia universalis unresponsive to treatment with tofacinitib: report of a case with a brief review of the literature. AB - Janus kinase inhibitors are emerging treatment alternatives in various immune mediated diseases including alopecia universalis. Herein, we report a patient with psoriasis and alopecia universalis in whom treatment with tofacitinib led to remission of psoriasis without improvement in alopecia universalis. Despite the promising potential in alopecia areata treatment, research evaluating the efficacy of different Janus kinase inhibitors and possible prognostic factors related with a more favorable response are warranted. PMID- 29469707 TI - Retronychia: an underdiagnosed disease. AB - Retronychia is a recently described cause of ingrowth of the nail plate on the ventral surface of the proximal nail fold. Clinical features are repeated episodes of proximal paronychia, nail plate thickening, and occasionally granulation tissue emergence. The usual treatments for paronychia such as antibiotics and antifungals are ineffective in these cases. Avulsion of the nail plate is the treatment of choice for these patients, but effective treatment is usually delayed owing to inadequate diagnosis. Herein, we describe a 28-year-old woman with a case of retronychia. She was treated for two months with oral and topical antifungal and antibiotics by her general practitioner. After proper diagnosis and avulsion of the nail she presented a normal and non-painful growth of the affected nail. PMID- 29469708 TI - Annular elastolytic giant cell granuloma: a "visible" diagnosis. AB - Annular elastolytic giant cell granuloma (AEGCG) is a rare granulomatous skin disease of undetermined cause, characterized by annular plaques with raised erythematous borders in sun-exposed skin. The typical histologic features are dermal infiltration by multinucleated giant cells, elastin degeneration, and elastophagocytosis. The authors describe a clinical case of AEGCG, which exhibited an excellent response to hydroxycloroquine. PMID- 29469709 TI - Ustekinumab to target granulomatous dermatitis in recalcitrant ulcerative necrobiosis lipoidica: case report and proposed mechanism. AB - We present a 42-year-old woman with no history of diabetes or glucose intolerance who had a 5-year history of ulcerative necrobiosis lipoidica (NL). Despite failure of multiple medications, she experienced clearing of her ulcers after her treatment was changed to ustekinumab. We discuss our patient's disease course and elaborate upon mechanistic reasons for her improvement related to ustekinumab therapy. PMID- 29469710 TI - Congenital isolated leukonychia. AB - Congenital leukonychia is a rare nail disorder that may occur in isolation or in association with a number of syndromic disorders. In the following letter, we describe a case of isolated congenital true leukonychia to add to the current literature. This case is particularly unique in that it does not appear to be inherited in an autosomal dominant fashion, in contrast to the majority of reported cases. PMID- 29469711 TI - Value of dermoscopy for the diagnosis of monilethrix. AB - Monilethrix is a rare genodermatosis characterized by a hair shaft dysplasia responsible for hypotrichosis. We report the case of a child with monilethrix with no associated cases in the family. Trichoscopy facilitated the diagnosis. A 2-year-old boy presented with diffuse alopecia and persistent fragile hair for several months. Clinical examination revealed alopecia with hairs broken several millimeters from the scalp. Trichoscopy revealed zones of dystrophic constriction of the hair shaft, separated at regular intervals by elliptical nodes of normal thickness, giving a "necklace" appearance. The diagnosis of monilethrix was made on the basis of these specific features. The diagnosis of monilethrix was more difficult to establish in our patient owing to the absence of any familial cases. PMID- 29469712 TI - Future growth of physicians and non-physician providers within the U.S. Dermatology workforce. AB - Trends in the training, supply, availability, career decisions, and retirement of US dermatology physicians are not well delineated. The current study evaluates whether growth in the dermatology workforce will keep pace with population expansion in the United States. A dermatologist supply model was projected to 2030 drawing on data from the American Academy of Dermatology, American Medical Association, Bureau of Labor Statistics, American Association of Medical Colleges, and other associations. The clinically active dermatologist workforce in 2015 was 36 per capita (1,000,000); entry following postgraduate training was age 30 with career separation at age 65 on average. Added to the provider model are physician assistants and nurse practitioners in dermatology practices. A linear regression micro simulation model based on age cohorts produced a per capita supply of dermatology providers of 61 (+/-3) per 1,000,000 by 2030, up from 47 in 2016. The dermatology workforce is growing faster than population expansion. Workforce estimates could be affected by changing trends in retirement and training of dermatology providers. Investments in training of nurse practitioners and physician assistants, in addition to training more doctors, may be an effective strategy for increasing access to care in populations with low dermatologist density. PMID- 29469713 TI - Video-based education about systemic corticosteroids enhances patient knowledge more than verbal education: A randomized controlled trial. AB - BACKGROUND: Video-based patient education about long-term systemic corticosteroid treatment has not been assessed. OBJECTIVE: To compare video-based versus verbal education in patient knowledge gained and satisfaction. METHODS: English-speaking adults (>=18 years) were recruited from March-August 2013 from medical dermatology clinics. Study provider clinics were the unit of randomization. Verbal subjects heard a script based on the standard discussions of two top systemic corticosteroid prescribers at Emory. Video subjects viewed a video developed by the investigators. A 12-item survey created by the the investigators assessed baseline and post-education knowledge (immediate, one-, three-, and six month). RESULTS: Baseline knowledge scores averaged 7.2+/-2.2 correct answers with no between-group differences. Post-education, the video group's (N=39) mean paired score difference was 0.9+/-2.0 higher than the verbal group's (p<0.04). After 1 month, most scores maintained gains with no between-group differences. 97% of patients in each group were satisfied (none were unsatisfied) with their education. LIMITATIONS: Our cohort was more literate than the general public, and a minority of subjects completed long-term follow up assessments. CONCLUSION: Video education enhanced near-term patient knowledge more than verbal education and maintained patient satisfaction. PMID- 29469714 TI - Risky business: Behaviors associated with indoor tanning in US high school students. AB - BACKGROUND: Understanding of associations between indoor tanning and risky health related behaviors such as sexual activity and substance abuse among high school students across the United States is incomplete. OBJECTIVE: To identify risky health related behaviors among high school students utilizing indoor tanning and analyze differences between state specific data. METHODS: Results from the Youth Risk Behavior Surveillance System (YRBSS) 2013 in 14 different states were analyzed. Participants were 90,414 high school students. Responses to questions assessing indoor tanning habits, sexual activity, and use of substances were analyzed. RESULTS: Sexual activity was associated with indoor tanning in 10 of 14 states, with Nebraska having the strongest association (adjusted odds ratio, 3.8; 95% CI, 2.4-6.2; p<0.001). Indoor tanning was also associated with use of alcohol, marijuana, ecstasy, cocaine, prescription medications, and cigarettes. LIMITATIONS: Only 15 states asked students about their personal history of indoor tanning use, and Minnesota was excluded from our analysis as they administered a non-YRBS questionnaire. Additionally, our study only analyzed results from the 2013 YRBS. Lastly, our data was analyzed in 14 individual data sets, giving a high likelihood of Type 1 error. CONCLUSIONS: High school students utilizing indoor tanning are more likely to engage in sexual activity and substance abuse as compared to students who do not utilize indoor tanning. PMID- 29469715 TI - Assessment of risk and use of prophylaxis for glucocorticoidinduced-osteoporosis among dermatologists in the Pacific Northwest: a survey study. AB - OBJECTIVE: Exposure to even physiologic doses of glucocorticoids can reduce one's bone mass and increase risk for osteoporotic fracture. There currently exists a wide variation in clinician approach to the assessment and management of glucocorticoid-induced osteoporosis (GIO). Our objectives were to characterize Pacific Northwest dermatology providers' general practices, assessment of risk for GIO, and preferred GIO prophylaxis measures by way of survey. To identify whether knowledge deficits exist with respect to preventing and managing GIO in dermatology patients. DESIGN: A self-administered, 22-question survey was sent electronically to respondent population. Surveyed population composed of 392 dermatology providers of the Washington State Dermatology Association and Oregon Dermatology Society registries. Survey responses were collected anonymously via Catalyst WebQ. RESULTS: Respondents over-estimated fracture risk and reported they would prescribe antiresorptive medications at a less-than-adequate rate. When given clinical scenarios and asked to assess risk of major osteoporotic fracture, respondents frequently overestimated risk compared to that estimated by the FRAX tool (67%-71%). When asked directly if one would prescribe bisphosphonates as GIO prophylaxis for a high-risk patient, only 49% responded always/almost always. CONCLUSIONS: This study suggests that a knowledge deficit exists within dermatology with respect to prevention and screening of GIO. The resultant practice gap is likely contributing to morbidity and mortality for dermatology patients requiring chronic glucocorticoid use for dermatologic disorders. Provider variability in practices suggests that dermatology could benefit from additional education in assessment and treatment of GIO, as well as a clear set of guidelines for GIO management. PMID- 29469716 TI - Associated conditions in patients with multiple dermatofibromas: Case reports and literature review. AB - Dermatofibromas are benign, fibrohistiocytic, dermal tumors. Solitary dermatofibromas may be incidental findings, whereas multiple dermatofibromas may be associated with systemic conditions or previous therapies. Two women and one man with multiple dermatofibromas and an associated systemic condition, immunosuppression, or both, are described. Nine dermatofibromas developed in a woman with hypothyroidism, optic neuritis, and Arnold Chiari I malformation. Five dermatofibromas developed in a woman with breast cancer who had received several systemic antineoplastic therapies. Eleven dermatofibromas developed in a man with HIV whose systemic therapies included acyclovir, darunavir/cobicistat, dolutegravir, etravirine, and ritonavir. Conditions associated with multiple dermatofibromas include autoimmune diseases, cancer, chromosomal abnormalities, immunodeficiencies, metabolic disturbances, and altered physiologic states such as pregnancy. Medications received by patients with multiple dermatofibromas included immunosuppressive agents, psoriasis therapies, and antineoplastic drugs. Multiple dermatofibromas can be observed in patients with associated medical conditions, systemic therapies, or both. Therefore, in individuals presenting with multiple dermatofibromas, not only evaluation for associated disorders, but also review of prior and current drug therapies, should be considered. PMID- 29469717 TI - Familial pseudoxanthoma elasticum associated with multiple comedones. AB - Pseudoxanthoma elasticum (PXE) is an autosomal recessive disorder characterized by atypical elastic fibers that causes connective tissue abnormalities of the skin, eyes, and heart, among other organs. The disorder is rare, with a classic presentation of yellow-orange cobblestone-like papules on flexural areas, lax skin, ocular degeneration, and moribund vasculature in multiple organs. There is wide variability in the presentation of the affected organs [1]. We present two sisters with classic cutaneous findings of PXE with the additional unusual findings of numerous open comedones on the neck. To our knowledge, this is the first report of numerous open comedones in familial PXE. PMID- 29469718 TI - Eccrine squamous syringometaplasia in an allogenic stem cell transplant patient undergoing chemotherapy. AB - Eccrine squamous syringometaplasia (ESS) is a rare finding defined as metaplastic change of the cuboidal epithelial cells of eccrine glands into two or more layers of squamous epithelial cells. We present a patient who developed ESS after induction of CLAG chemotherapy [2-Chlorodeoxyadenosine (2-CdA) with cytarabine (Ara-C) and (granulocyte-colony stimulating factor) G-CSF] for management of the blast crisis of his chronic myelogenous leukemia (CML). Our patient's ESS eruption presented with a variety of morphologies, thus multiple skin biopsies were taken to determine the possible diagnosis(es). All skin biopsies showed ESS and the eruption resolved with topical corticosteroids after CLAG therapy was finished. PMID- 29469719 TI - Simultaneous flagellate erythema in a husband and wife secondary to shiitake mushroom ingestion. AB - Flagellate erythema secondary to shiitake mushroom (Lentinus edodes) ingestion is a condition that was first documented in 1977 by Nakamura and has been reported in Japan, Europe, and the United States. Herein, we present two cases of flagellate erythema after a couple ate a meal containing shiitake mushrooms at a chain restaurant. We hypothesize that this condition may not be as rare or as dependent on volume of exposure as previously suggested, considering that two genetically unrelated individuals simultaneously developed the eruption after minimal exposure. PMID- 29469720 TI - Erythema multiforme major in a patient with metastatic melanoma treated with nivolumab. AB - Nivolumab, a relatively novel immune checkpoint inhibitor with FDA approval in 2014, is gaining greater utilization due to its efficacy in treating metastatic melanoma. Many of the cutaneous immune-related adverse events (irAEs) being catalogued do not necessitate discontinuation of immunotherapy and are managed with supportive therapy. We present a case of erythema multiforme major secondary to nivolumab requiring hospitalization and discontinuation of treatment. This is only the second reported case of nivolumab-induced erythema multiforme in the literature we are aware of, and emphasizes the importance of oncologists working in conjunction with dermatologists for prompt diagnosis and management. PMID- 29469721 TI - Lupus and scleroderma overlap features in a 28-year-old man with anti-PL-12 anti synthetase syndrome. AB - A 28-year-old man with clinically and laboratory diagnosed anti-PL-12 anti synthetase syndrome (AS) in 2009 developed cutaneous lupus lesions, discoid lupus lesions, and sclerodacytly with finger-tip ulcerations four years following his AS diagnosis. Laboratory tests including +ANA, +anti-dsDNA antibody, +anti-Smith antibody, and +anti-RNP antibody in 2014 confirmed the diagnosis of progression to an overlap syndrome including systemic lupus erythematosus. The patient now also has clinical findings (sclerodacytly, Raynaud phenomenon, finger-tip ulcerations) consistent with scleroderma overlap. In each stage of his evolving connective tissue disease, cutaneous findings have been central to the recognition and monitoring of his overlap syndromes. PMID- 29469722 TI - Acquired elastoma in a subungual location. AB - Elastomas are connective tissue nevi or hamartomas. They may occur in isolation or can be associated with familial syndromes such as Buschke-Ollendorff syndrome. Elastomas typically present in childhood as small ivory papules or firm skin colored nodules that can coalesce into larger yellow plaques. These lesions are typically distributed over the extremities, abdomen, and back. Herein, we report an unusual case of a renal transplant recipient who presented with an acquired subungual papule with associated koilonychia and distal nail plate dystrophy. Histopathologic findings were consistent with subungual elastoma. PMID- 29469723 TI - Mycobacterium haemophilum infection in a renal transplant patient with inflammatory bowel disease. AB - A 61-year-old immunosuppressed renal transplant patient with inflammatory bowel disease presented with tender pink nodules on the trunk and extremities. An initial biopsy was suggestive of metastatic Crohn disease, but after disease persistence, a second biopsy revealed disseminated Mycobacterium haemophilum. Atypical mycobacterial infections should be considered in immunosuppressed patients. This case highlights the complexities of diagnosing such infections in patients with an underlying granulomatous condition and the particular growth requirements of M. haemophilum. PMID- 29469724 TI - Oral lesions as an important marker for HIV progression. AB - BACKGROUND: Oral hairy leukoplakia (OHL) is a benign lesion caused by Epstein Barr virus (EBV) replication in the oral epithelium affecting the borders of the tongue. It is strongly associated with immunosuppression, especially in HIV+ adults but is uncommon in pediatric population. The aim of the study is to show the importance of the correct diagnosis of OHL and its influence on HIV treatment.We report two cases of HIV+ adolescent patients that presented with leukoplakic lesions on the border of the tongue, suggestive of OHL. OHL diagnosis was confirmed in only one case through EBV in situ hybridization. After confirmation of the diagnosis, the patient with OHL was referred to an infectious disease specialist with the decision to start antiretroviral therapy. CONCLUSION: OHL definitive diagnosis can help clinical management of pediatric HIV+ patients. PMID- 29469725 TI - Histiocytoid autoimmunity-related neutrophilic dermatosis in a patient with rheumatoid arthritis. AB - Autoimmunity-associated neutrophilic dermatoses are a recently recognized manifestation of connective tissue diseases, in particular, lupus erythematosus. These entities are clinically and sometimes histopathologically distinct from classic neutrophilic dermatoses. We describe a case of an autoimmunity-related neutrophilic dermatosis in a patient with rheumatoid arthritis. In addition to this uncommon association, there was an absence of mature neutrophils and a population of immature histiocytoid granulocytes. This unusual case expands the concept of histiocytoid neutrophilic dermatoses to include those seen in association with autoimmune connective tissue diseases. PMID- 29469726 TI - Psoriasiform mycosis fungoides: a rare form of the disease with review of the literature. AB - BACKGROUND: Mycosis fungoides (MF) typically presents as erythematous scaly patches or plaques that may progress to cutaneous tumors. Although MF may be presented like other dermatoses, initial presentation as psoriasiform plaques simulating psoriasis is rare. Differentiating MF from psoriasis is important because systemic therapies used for psoriasis can worsen MF. We describe a case of psoriasiform MF and we also review the clinicopathological features of similar cases in the literature. CASE: A 46-year-old woman was referred to our clinic with a history of psoriasiform plaques for 13 years. She had multiple, generalized, indurated plaques with thick psoriasiform scales that were unresponsive to topical treatments. The histopathology showed marked psoriasiform epidermal hyperplasia with epidermotropic atypical lymphocytes compatible with MF. Immunohistochemical (IHC) staining showed that atypical lymphocytes were positive for CD3, CD4, CD8, and CD5. Of note, upper dermal and intraepidermal large atypical lymphocytes were CD30 positive. The review of similar psoriasiform MF cases revealed that they had all been treated as psoriasis for many years and finally diagnosed as MF especially after deterioration induced by immunosuppressive therapies. CONCLUSIONS: In presumed cases of psoriasis that are unresponsive to treatment, progressive, or ulcerative, biopsy should be considered to rule out MF, particularly before starting a potent immunosuppressive agent. PMID- 29469727 TI - Painful subcutaneous nodules on the thigh. AB - Osteoma cutis is the presence of bone within the dermis or subcutaneous tissue. This condition may occur sporadically or secondary to other dermatologic or genetic conditions. We present a 12-year-old girl with pseudohypoparathyroidism type-Ia who developed osteoma cutis on the right thigh. PMID- 29469728 TI - Generalized eruptive syringomas. AB - Eruptive syringoma is a rare variant of syringoma, benign neoplasms of the eccrine sweat ducts that appear on the face, neck, chest, and axillae of predominately Asian and African American women before or during puberty [1, 2]. Lesions appear as small skin-colored or slightly pigmented, flat-topped papules [2]. The condition can be cosmetically disfiguring and difficult to treat, especially in dark-skinned patients. The investigators report a 52-year old Guyanese woman who presented with widespread, chronic, non-pruritic and nontender, skin-colored papules that arose approximately 20 years earlier. A punch biopsy of affected skin was obtained and the histological diagnosis was eruptive syringoma. The patient pursued no further treatment, after discussion of costs and risks. PMID- 29469729 TI - A pedunculated lesion on the foot: acquired fibrokeratoma. AB - Acquired fibrokeratomas are benign and uncommon lesions consisting of collagenous papules and nodules covered by hyperkeratotic epidermis. These tumors occur mainly on the fingers and toes and infrequently on the palms and soles. They may possibly be triggered by a reaction to a trauma and presents as small and solitary dome-shaped lesions with a collarete of slightly raised skin at the base. Several case reports have been published of this rare lesion, with only a few investigators describing lesions of the feet. PMID- 29469730 TI - A giant apocrine hidrocystoma of the trunk. AB - Hidrocystomas are benign cysts that typically present as translucent, bluish dermal nodules on the face and are rarely > 1 cm in size. They are classically categorized as eccrine or apocrine based on histologic features. We present a rare case of a giant apocrine hidrocystoma of the trunk, demonstrating that, although a rare variant, apocrine hidrocystomas can present both off the head and neck, and can be significantly larger in size than previously reported. PMID- 29469731 TI - Local skin reactions following the administration of topical ingenol mebutate for actinic keratosis. AB - Actinic keratoses are cutaneous lesions that appear as the result of the proliferation of atypical keratinocytes. These lesions are considered pre malignant and they can progress to squamous cell carcinoma. Ingenol mebutate has been approved as an effective treatment for AK on the face and trunk. We studied the local skin reactions to this therapy. Data about local skin reactions were collected in a series of 5 patients with photographic documentation, a visual analog scale, and a ranking of satisfaction of the patient. Moderate to severe reactions were reported in most of patients, but only one stopped treatment early. The short duration of treatment contributes to high adherence to the therapy.

PMID- 29469733 TI - Nasolabial flap - alternative uses for a classic but versatile technique. AB - The nasolabial flap is one of the most ancient techniques used in orofacial surgery. The authors report two cases of patients with skin cancer treated surgically with variations of the classic nasolabial flap by transposition (bilateral and folded) that highlight the broad applicability of this technique. PMID- 29469734 TI - Clinical resolution of pemphigus vulgaris on rituximab. AB - Although significant progress has been made for the treatment of pemphigus vulgaris (PV) with rituximab (RTX), a consensus remains to be determined for standard treatment protocol, regarding optimal dosing, infusion regimen, and use of concomitant immunotherapy to achieve safe, effective, and rapid clinical response. We describe a patient with pemphigus vulgaris treated with high dose rituximab with the rheumatoid arthritis protocol along with intravenous immunoglobulin therapy. This case provides evidence towards the growing body of research needed to modify and improve treatment for pemphigus using rituximab. PMID- 29469735 TI - Quantitative ABCD parameters measured by a multispectral digital skin lesion analysis device for evaluation of suspicious pigmented skin lesions strongly correlate with clinical ABCD observations. AB - : Background/Study Aim: A multispectral digital skin lesion analysis (MSDSLA) device has proven to be sensitive and specific for malignant melanoma (MM) detection by dermatologists and may have other useful applications. This study aimed to develop and test objective quantitative Asymmetry, Border irregularity, Color, and Diameter (qABCD) parameters for MSDSLA and correlate them with the presence of clinical ABCD features to aid the decision to biopsy a suspicious pigmented skin lesions (PSLs). METHODS: 1632 benign and malignant [175 MM/High Grade Dysplastic Nevi (HGDN)] were evaluated for their qABCD parameters. Quantitative characteristics were correlated with the presence of clinical ABCD features identified by independent dermatologists. RESULTS: qA, qB, qC, and qD had correlations of 78%, 73%, 76%, and 86%, respectively, for non-MM/HGDN lesions. The correlations for qA, qB, qC, and qD for MM/HGDN lesions was 86.3%, 83%, 89%, and 89%, respectively. All repeatability parameters were statistically significant. CONCLUSIONS: This study demonstrates qABCD values are repeatable and strongly correlate with the clinical ABCD features. qABCD characteristics provide an additional objective and reliable means of identifying PSLs that need further evaluation to rule out MM and, in combination with the clinical ABCDs, may allow for improved assessment when evaluating the malignant potential of PSLs. PMID- 29469736 TI - The impact of ultraviolet radiation on sunburn-related search activity. AB - We establish a strong, positive relationship between the Ultraviolet Index and Google search engine activity for sunburn-related terms in the United States. Using the Google Trends utility and data available from the National Weather service, we combine data from a twelve-year period to produce panel data for each state. We fit a time-series regression model of search activity and perform statistical tests on the resulting parameter estimates. This study lays the groundwork for using search-related data to assess the prevalence of, and attitudes about sunburn. By tracking the frequency of searches about preventative measures like "sunscreen" or "protective clothing" versus treatment measures like "sunburn relief," researchers could measure the effectiveness of awareness and prevention programs. PMID- 29469737 TI - Telangiectasia macularis eruptiva perstans: an old terminology, still frequently used. AB - The term telangiectasia macularis eruptiva perstans (TMEP) was originally used to describe a rare form of cutaneous mastocytosis (CM) that was limited to the skin with lesions consisting of irregular, telangiectatic macules ranging in color from red to brown. Recent guidelines, however, recommended that the sole presence of telangiectasias should not form the basis of a distinct variant of CM. We conducted a review of the literature from 1930 to 2017 and found 76 cases that were reported as TMEP. Owing to a general misconception about diagnosis of CM and SM, there is a need for further discussion and awareness of the newly proposed World Health Organization (WHO) guidelines. PMID- 29469738 TI - Dermatologic manifestations of acromegaly: A case in point and a focused review. AB - Acromegaly is a systemic syndrome caused by overproduction of growth hormone. Cutaneous, endocrine, cardiovascular, skeletal, and respiratory systems are affected. Cutaneous changes in acromegaly relate to overexpression of growth hormone and insulin-like growth factor 1 on skin cells and adnexa. Dermal glycosaminoglycan accumulation and edema cause skin distention that is most prominent in the face, hands, and feet. Oily skin with large pores, hypertrichosis, and excessive sweating are common features. Pigmented skin tags, acanthosis nigricans, and psoriasis are also encountered. Cutaneous manifestations of acromegaly are various and prominent, and are an important clue for the early diagnosis and treatment of this high-morbidity disorder. PMID- 29469739 TI - Cowden syndrome: clinical case and a brief review. AB - Cowden syndrome is a rare genodermatosis of autosomal dominant inheritance characterized by multiple hamartomas in several organs and an increased risk of malignancies. We present the case of a 53-year-old man with a history of benign and malignant thyroid disease, intestinal polyposis, and Chiari malformation. He had several trichilemmomas, papillomatosis of the oral cavity, macular pigmentation of the glans penis, among other clinical features suggestive of Cowden syndrome. Given the suspicion, genetic study was conducted and PTEN mutation was identified. Cowden syndrome affects 1:200,000 individuals. Mucocutaneous lesions are almost always present and there may be other typical features involving other organs, namely thyroid, colon, and brain. Mucocutaneous lesions may be the initial manifestation of this disorder and usually precede the onset of malignant lesions, making timely diagnosis essential for proper monitoring and screening. PMID- 29469740 TI - A toxic epidermal necrolysis-like presentation of linear IgA bullous dermatosis treated with dapsone. AB - Linear IgA bullous dermatosis is a rare autoimmune vesiculobullous disease characterized by linear deposition of IgA along the basement membrane zone. It is classically idiopathic, but may also arise secondary to drug exposure. A heterogeneous spectrum of clinical features has been described, including a rare, morbid variant mimicking toxic epidermal necrolysis. Herein, we present a case of vancomycin-induced linear IgA bullous dermatosis that manifested clinically as toxic epidermal necrolysis and resolved with dapsone therapy. PMID- 29469741 TI - An unusual presentation of primary cutaneous amyloidosis. AB - Primary localized cutaneous amyloidosis refers to a group of disorders characterized by deposition of amyloid in the dermis without any systemic involvement. It comprises the following clinical types: macular, lichenoid, nodular, and biphasic. There are also rare variants such as amyloidosis cutis dyscromica and poikiloderma-like cutaneous amyloidosis. We report a case of primary cutaneous amyloidosis in a 17-year-old boy with unusual pigmentation of various patterns (reticulate and diffuse pigmentation with mottling and rippling at places) and hypopigmented atrophic macules. Our patient also had nail, oral, and mucosal pigmentation that have not been described. Amyloid deposits were shown histopathologically in both hyperpigmented and hypopigmented macules.

AB - The association between guttate psoriasis and infection with group A Streptococcus (GAS) has been well established in the medical literature. However, responses to treatments aimed at GAS eradication such as systemic antibiotics or tonsillectomy are inconsistent. Further complicating treatment recommendations for a disease with a suspected microbial trigger, the standard therapy for severe psoriasis is with systemic immunosuppressant medications. This case report illustrates the role of GAS as a trigger for acute onset severe psoriasis in a child whose skin disease initially worsened with a trial of methotrexate. An immune evaluation confirmed a co-existing selective antibody deficiency. Subsequent treatment with intravenous immune globulin dramatically improved his underlying immune function and decreased GAS infections. This improvement in overall immune function and decrease in GAS infections cleared his skin disease. An interval change in formulation to subcutaneous immune globulin was not as effective.

AB - Mycosis fungoides (MF) is the most common cutaneous T cell lymphoma that involves the oral mucosal. The manifestation of lesions within the oral cavity generally correlates with a poor prognosis. Management of MF includes skin directed therapies and localized radiation treatment, with systemic biologic therapies and chemotherapy used for more advanced stages. The clinical and histologic features of MF in a patient with oral disease are reviewed. PMID- 29469745 TI - Oral involvement of cutaneous T-cell lymphoma. AB - Methylisothiazolinone (MI) is commonly used as a preservative in personal care products and is a frequent cause of allergic contact dermatitis. We present a patient with allergic contact dermatitis caused by MI in hair care products and discuss this allergen to bring attention to this common cause of contact dermatitis, and to highlight its frequent use in hair care products. If allergy to MI is suspected, testing should be performed to this individual preservative, as testing solely for the combination preservative, methylisothiazolinone/methylchloroisothiazolinone (Kathon CG(r)), may miss many cases of MI allergy.

Multiple ES is a rare variant of ES and can present in a segmental, linear, blaschkoid, or zosteriform pattern. The etiology of multiple ES is unknown, but several theories have been suggested including a multipotent stem cell origin. We report the case of a 30-year-old woman with multiple painful ES in a zosteriform pattern on the mid-back and abdomen. Skin biopsy of a representative lesion demonstrated a circumscribed tumor nodule encapsulated by a fibrous capsule with diffuse dense basophilic proliferation located in the dermis. The lesions were then excised on two separate sessions without recurrence. PMID- 29469747 TI - Multiple eccrine spiradenomas in a zosteriform pattern.

PMID- 29469748 TI - Mycobacterium marinum infection contracted from seaweed wrap in a psoriasis patient undergoing treatment with adalimumab. AB - We report a patient with psoriasis who developed Mycobacterium marinum (M. marinum) infection after seven years of treatment with adalimumab, a human anti TNF (tumor necrosis factor) monoclonal antibody. TNF is a pro-inflammatory cytokine that plays a central role in the pathogenesis of psoriasis and a number of other immune-mediated inflammatory diseases. TNF plays an important role in granuloma formation and host defense against mycobacterial infections. Several cases of atypical mycobacterial infections in patients on TNF inhibitors have been reported. To our knowledge, this is the second reported case of M. marinum infection in a patient on adalimumab for the treatment of psoriasis. PMID- 29469750 TI - A case of probable trimethoprim-sulfamethoxazole induced circulating antineutrophil cytoplasmic antibody-positive small vessel vasculitis. AB - Cutaneous leukocytoclastic vasculitis (LCV) can occur as skin-limited disease or as part a systemic vasculitis. Appropriate workup includes the evaluation of antineutrophil cytoplasmic antibodies (ANCAs), with a positive titer raising concern for the associated primary vasculitides including microscopic polyangiitis (MPA), granulomatosis with polyangiitis (GPA), or eosinophilic granulomatosis with polyangiitis (EGPA). In the absence of systemic findings, however, a drug etiology must also be considered. Tumor necrosis factor (TNF) inhibitors, propylthiouracil, levamisole-adulterated cocaine, hydralazine, and minocycline have been previously documented to induce ANCA-positive vasculitis (APV), which may present with conspicuously high ANCA titers. Herein we report trimethoprim-sulfamethoxazole as another culprit in drug-induced APV. Our case reinforces the need to consider drug etiology for APV and cautions against interpreting positive ANCAs as equivalent to evidence of systemic disease. PMID- 29469749 TI - Trimethoprim-sulfamethoxazole-induced linear IgA bullous disease presenting as toxic epidermal necrolysis. AB - BACKGROUND: Linear IgA bullous dermatosis (LABD) is an autoimmune blistering skin disorder characterized by linear IgA deposits along the dermoepidermal junction. Usually idiopathic, LABD can be drug-induced. OBJECTIVE: To report the atypical characteristics of a case of trimethoprim-sulfamethoxazole-induced LABD presenting as toxic epidermal necrolysis (TEN). METHODS: A 63-year-old woman treated with trimethoprim-sulfamethoxazole for Pneumocystis jirovecii infection developed a generalized maculopapular rash with herpetiform lesions, rosette-like lesions, and tense bullae with Nikolsky sign. RESULTS: Anti-basement membrane zone antibodies were negative, but immunoblot revealed a 160 kDa band corresponding to subepidermal class IgA desmoglein 1. Skin biopsy specimens revealed a subepidermal bulla and direct immunofluorescence showed linear IgA deposition along the basement membrane zone. A diagnosis of toxic epidermal necrolysis was excluded and replaced by trimethoprim-sulfamethoxazole-induced LABD. CONCLUSION: We report a case of trimethoprim-sulfamethoxazole-induced LABD with a 160 kDa IgA desmoglein 1 found by immunoblotting analysis, probably by epitope spreading. PMID- 29469751 TI - Staphylococcus lugdunensis cutaneous infection with sporotrichoid distribution. AB - We report the occurrence of Staphylococcus lugdunensis cutaneous infection with sporotrichoid distribution of the left lower limb of a 60-year-old man. Recent studies have confirmed that Staphylococcus lugdunensis is a significant pathogen in causing skin and soft tissue infections that usually manifest in abscesses, surgical wound infections, and cellulitis. It used to be considered a skin commensal bacteria, but if unrecognized it can lead to fulminant endocarditis, meningitis, skin abscesses, peritonitis, and spondylodiscitis. PMID- 29469752 TI - Cutaneous infection with Mycobacterium fortuitum after subcutaneous injection of human chorionic gonadotropin. AB - Weight loss clinics are common in the United States. Unfortunately, some offer dubious weight loss methods such as self-administered human chorionic gonadotropic (HCG) injections. HCG products are unregulated, yet, widely available. Infection is among the risks potentially associated with this treatment. We report a case of skin infection caused by Mycobacterium fortuitum after HCG injection. PMID- 29469753 TI - A case of de novo palmoplantar psoriasis with psoriatic arthritis and autoimmune hypothyroidism after receiving nivolumab therapy. AB - Nivolumab, a monoclonal antibody against the programmed cell death protein 1 (PD 1), has shown promising results in patients with advanced malignancies, including melanoma, lung cancer, and renal cancer. Immune-related adverse events (irAEs) have been reported, including both organ-specific toxicities and skin toxicities. Herein, we report a case of predominantly palmoplantar psoriasis with severe nail involvement, psoriatic arthritis, and autoimmune hypothyroidism after receiving nivolumab treatment for lung cancer. We also summarize the case reports that have been published previously. The knowledge of these irAEs in patients undergoing anti-PD1 therapy is important since it will enable earlier recognition and appropriate management, with the aim of maintaining effective dose without disruption. PMID- 29469754 TI - Clinical improvement of a patient with both amyopathic dermatomyositis and psoriasis following treatment with cyclosporine. AB - Clinically amyopathic dermatomyositis (CADM) is an uncommon subtype of dermatomyositis that rarely presents simultaneously with psoriasis. There are subsequently few reports discussing the management of concurrent CADM and psoriasis. Furthermore, skin lesions of CADM are often recalcitrant to first line dermatomyositis interventions. We present a case of a 45-year-old woman with both CADM and psoriasis whose lesions were resistant to multiple therapies; she eventually achieved disease control and remission with cyclosporine. PMID- 29469755 TI - Atypical presentations of pityriasis rosea: a reply. AB - Pityriasis rosea (PR) may have atypical presentations as regards morphology and distribution of the lesions. Recently, several forms of PR considered atypical for the course of the disease have been described. Differently from the typical PR that resolves within 2-12 weeks, relapsing and persistent PR forms (lasting longer than 12 weeks) have been described in adults and children. Lesions of the oral mucosa in PR may be more common than as reported in the literature. Formerly, the occurrence of oral lesions in PR has been considered more frequent in dark-skinned patients compared to light-skinned patients. However, in 12 Caucasian adult patients with persistent PR that have been recently described, oral lesions were very common (75% of cases). Another study on the clinical features and virological parameters of 31 Caucasian children with PR showed that painless oropharyngeal lesions were present in 35% of them, a rate much higher than those reported in adult dark-skinned (9%) and Caucasian patients (16%) with typical PR. PMID- 29469756 TI - Essential telangiectasia in an infant: a diagnosis to be considered. AB - Essential generalized telangiectasia as the result of postcapillary venule dilatation, is characterized by the sudden development of generalized telangiectasias, sometimes involving the conjunctiva. A few pediatric cases have been reported. The main condition in the differential diagnosis includes syndromes with telangiectasia such as hereditary hemorrhagic telangiectasia of Rendu-Osler, unilateral nevoid telangiectasia, and neonatal lupus erythematous. We present an 11-month-old boy that presented because of telangiectasia located on the face and neck. The telangiectasias appeared at two months of age and followed a progressive course. Nd-YAG laser therapy could be an interesting therapeutic approach in cosmetically compromised cases. PMID- 29469757 TI - Delusions of parasitosis: a brief review of the literature and pathway for diagnosis and treatment. AB - A large proportion of patients seen in dermatology practices have underlying psychological issues associated with their skin diseases. One of the most flagrant examples of this are patients with delusions of parasitosis. These patients have false fixed beliefs that they are infested by parasites and experience cutaneous sensations of crawling, biting, and stinging associated with their delusions. There is no organic skin disorder and all cutaneous manifestations are self-induced. Rather than a psychiatrist, the dermatologist is often designated by the patient to handle the chief complaint, even though the main disorder is psychogenic. In spite of their limited evidence, antipsychotic medications have become the mainstay of therapy for delusions of parasitosis. The dermatologist must therefore be familiar with the approach to diagnosis and the use of antipsychotic or neuroleptic medications, which usually reside in the domain. There are few clinical trials and no substantial randomized controlled trials examining the efficacy of the psychiatrist antipsychotic medication used to treat delusions of parasitosis. This review article synthesizes the current available research and distils it down to analyzes 17 case reports, comprising 37 cases, examining the use of risperidone and olanzapine in the treatment of delusions of parasitosis. These findings are synthesized into a clinical pathway designed to assist dermatologists in effectively managing patients with delusions of parasitosis. PMID- 29469758 TI - A pilot program for community dermatologists working with primary care residents to provide dermatology consults to a regional hospital. AB - With the high demand and limited supply of dermatologists, the majority dedicate their time primarily to outpatient practice. A number ofobstacles to inpatient dermatology consults have been described, as well as the essential benefits for some of the sickest patients. Dermatology residency programs partially relieve this need, however with the transition to a single Graduate Medical Education accreditation system and many previously American Osteopathic Association accredited dermatologyprograms ceasing to train residents after 2020, it is prudent to recruit additional possible consultants. One possible solution is to involve non-dermatology residents as part of the consult service team. We report on our experience of piloting such a program, for community dermatologists providing consults to a regional hospital utilizing family medicine andinternal medicine residents. PMID- 29469759 TI - Vaccine-induced toxic epidermal necrolysis: A case and systematic review. AB - BACKGROUND: Erythema multiforme (EM), Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are cutaneous hypersensitivityreactions that develop in response to specific triggers such as medications and certain infections. Vaccines, which undergo rigorous safety testing prior to use in humans, are a rare cause of SJS/TEN and little is known about the frequency of such events and corresponding pathogenesis. OBJECTIVE: Herein, we discuss a case of suspected TEN in a 19-year-old woman who received the meningococcal B vaccine (the first report of such an association) and conduct a systematic review of the associated literature. We also discuss management of this patient with a single dose of etanercept. METHODS: Relevant literature was searched using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method. RESULTS: A total of 29 articles reporting EM, SJS, or TEN following vaccination were included from >5 countries. Of the 29, 22 articles reported EM, 6/29 reported SJS, and 4/29 reported TEN (3 articlesreported cases of both EM and SJS/TEN). CONCLUSIONS: We suggest consideration of vaccines as an etiology for cases of SJS or TEN that begin with an EM-like presentation, and provide further evidence for the use of etanercept as a viable treatment for TEN. PMID- 29469760 TI - The use of cyclosporine for Stevens-Johnson syndrome-toxic epidermal necrolysis spectrum at the University of Louisville: A case series and literature review. AB - INTRODUCTION: Cyclosporine therapy for Stevens-Johnson syndrome-toxic epidermal necrolysis (SJSTEN) was first reported in the literature by Renfro et al. in 1989. Herein we report an additional 4 cases of SJS-TEN treated with cyclosporine. METHODS: Case information was collected retroactively at the University of Louisville Hospital in Louisville, KY. All cases had a diagnosis of SJS or TEN by a dermatologist. All patients were >=18 years of age and treated with cyclosporine during their admission. RESULTS: Three of four patients re epithelialized within an average of 3.67 days of starting 3-4 mg/kg/day of cyclosporine. One patient passed away, likely due to advanced endometrial cancer. DISCUSSION: We provide a review of the literature on cyclosporine use for SJS/TEN, including various outcome measures - stabilization (cessation of new lesions), time to re-epithelialization, mortality rate, and hospital length of stay and, where available, comparison to other systemic agents. CONCLUSION: The outcomes appear to be consistent with rapid re-epithelialization and low mortality as seen in many previous reports. Treating SJS-TEN with systemic agents including cyclosporine will remaincontroversial because the vast majority of data comes from case reports, case series, or small open prospective trials. PMID- 29469761 TI - Schnitzler syndrome in a patient with a family history of monoclonal gammopathy. AB - Schnitzler syndrome is a rare disease characterized by chronic urticaria and a monoclonal gammopathy, most commonly IgM with light chains of the kappa type. There are currently no known risk factorsassociated with development of the disease. We report a case of Schnitzler syndrome in a 48-year-old man with a family history of monoclonal gammopathies. The patient's disease has been well controlled with anakinra therapy. Our case may contribute to a better understanding of the etiology of Schnitzler syndrome as his history could suggest a hereditarypredisposition for the disease. Further studies are necessary to determine whether a genetic component of Schnitzler syndrome exists, as first degree relatives of patients with monoclonal gammopathies may be at risk for the development of the disease. PMID- 29469762 TI - Anaplastic large cell lymphoma localized to the left breast years after radiotherapy for breast cancer. AB - Anaplastic large cell lymphoma (ALCL) is a rare type of non-Hodgkin lymphoma that can involve the skin primarily or secondarily. Our case describes an unusual presentation of eruptive tumors localized to the leftbreast region several years following breast cancer surgery and radiation for carcinoma of the breast. This report highlights the challenges in reachingthe diagnosis of an aggressive systemic lymphoma presenting on the skin. PMID- 29469763 TI - Unusually extensive scalp ulcerations manifested in pemphigus erythematosus. AB - Senear-Usher Syndrome, or pemphigus erythematosus, is an autoimmune skin blistering disorder with an overlapping clinical presentation of pemphigus foliaceus and lupus erythematosus. Lesions typically involve the scalp, face, and upper chest or back. This case study focuses on a patient who presentedwith progressive scalp ulcers, hyperpigmentation, and eroded plaques with overlying hemorrhagic crust. Pemphigus erythematosus was diagnosedwith direct immunofluorescence, demonstrating immunoglobulin G and complement deposition both intercellularly and at the dermoepidermal junction. The patient is continuing treatment with systemicsteroids and steroid-sparing immunosuppressants. PMID- 29469764 TI - Focal linear elastosis in a patient with joint hypermobility syndrome. AB - Focal linear elastosis (FLE) is a benign skin findingcharacterized by hypertrophic linear plaques withabnormal elastic fibers on histology. We present aunique case in which focal linear elastosis occurredin the setting of joint hypermobility syndrome(JHS). Our patient, a 20-year-old man with a medicalhistory significant for symptoms consistent with JHS,had been followed by the rheumatology clinic formany months. He was referred to the dermatologydepartment for further evaluation of asymptomaticlongitudinal bands on his back that had been presentfor many years. He denied trauma but endorsed ahistory of 'stretch marks.' On examination there werenumerous horizontally oriented, firm, linear, yellowto flesh colored bands, all non-tender to palpation.Punch biopsies were performed of involved anduninvolved skin. Histopathology of normal skinrevealed no significant abnormalities whereasinvolved skin demonstrated broadened collagenbundles in the deep dermis. The elastic fiber stain,Verhoeff-Van Gieson, revealed a gross increase in thenumber of elastic fibers, fragmented fibers, fiberswith "paintbrush" or widened-ends, fibers of varyingthickness, and clumped fibers. This combination ofhistopathologic and clinical features was consistent with FLE. PMID- 29469765 TI - Nivolumab reactivation of hypertrophic lichen planus, a case report and review of published literature. AB - We report a case of nivolumab-induced lichen planus (LP) reactivation that was previously in remission following chemotherapy for non-smallcelllung cancer (NSCLC). Chemotherapy-induced immunosuppression allowed for complete resolution of the patient's pre-existing LP, a T-cell mediatedautoimmune process. When the patient was switched to nivolumab immunotherapy owing to progression of NSCLC, PD 1 inhibition led to an overwhelming T-cell response that seemed to have provoked a severe LPreactivation. Although lichenoid reactions have been reported with nivolumab, to our knowledge, this is the first reported case of nivolumab monotherapycausing LP reactivation in a patient with a strong personal and family history of the disease that was previously in remission after chemotherapy. PMID- 29469766 TI - Herpes zoster as a cause of atypical chronic ulcerations associated with tofacitinib. AB - Tofacitinib is a targeted inhibitor of janus kinase (JAK), currently approved for the treatment of rheumatoid arthritis. We present a patient on treatment withtofacitinib who had an episode of classic dermatomal herpes zoster followed months later by atypical chronic cutaneous ulcers also caused by herpes zoster. PMID- 29469767 TI - Eosinophilic infiltrate resembling eosinophilic cellulitis (Wells syndrome) in a patient with mycosis fungoides. AB - Mycosis fungoides (MF) is a T-cell, non-Hodgkin lymphoma that primarily involves the skin. Extracutaneous involvement, such as in the parotidgland, is characteristic of end-stage disease. Eosinophilic cellulitis, or Wells syndrome, is a rare inflammatory dermatitis that involves a dermal infiltrate of eosinophils. We report a case of an 80-year-old man with a long-standing diagnosis of stage IIB MF who acutely developed parotid gland involvement and marked hypereosinophilia that most likely represented eosinophilic cellulitis. Activated T cells from his MF were likely a trigger factor for the development of his eosinophilic cellulitis. To our knowledge, this is the first reported case of an MF patient with atypical parotid gland involvement andeosinophilic cellulitis. PMID- 29469768 TI - A novel association of pseudoainhum and epidermolytic ichthyosis, successfully treated with full thickness skin graft after failed z-plasty repair. AB - Pseudoainhum is a rare constriction band variant thatmay progress to spontaneous digital strangulationand auto-amputation. Although its association withpalmoplantar keratodermas is well established, ithas not been reported in conjunction with classicepidermolytic ichthyosis. We describe the first suchcase in a 25-year-old woman who presented witha painful constricting band of the fifth toe. We alsodescribe her treatment course, which consisted ofa failed z-plasty, the traditional therapeutic optionfor acute pseudoainhum, and report the success ofsubsequent full thickness skin graft, suggesting thebenefit of this procedure as a therapeutic alternativefor patients with pseudoainhum. PMID- 29469770 TI - Interstitial granulomatous dermatitis in a patient with chronic hepatitis C and mixed cryoglobulinemia. AB - A 55-year-old man presented with a history of asymptomatic, bilateral, figurate dermatosis consisting of erythematous, annular, linear, andarciform, indurated nodules and plaques on the lateral walls of thorax, flanks, and hypogastrium. His medical history was positive for chronic hepatitis C. Skin biopsy was compatible with the diagnosisof interstitial granulomatous dermatitis. Additionalinvestigation revealed positive rheumatoid factor, antinuclear antibodies, and cryoglobulins. Thepatient started treatment with high-potency topical corticosteroid. After 12 weeks of treatment there was a partial clinical improvement of thedermatosis. Interstitial granulomatous dermatitis exhibits a distinct histopathological pattern with a diverse clinical appearance, which can be associated with autoimmune systemic diseases, neoplasms, several drugs, and infections. Optimal therapy for this condition is yet to be established, but topical corticosteroids have been a mainstay of treatment. PMID- 29469769 TI - ?

AB - A 12-month-old boy presented with three months of asymptomatic hypopigmented flat topped papules on the suprapubic skin and lower abdomen. Emollients and topical steroids offered no improvementand the patient was referred to the dermatology department. Shave biopsy revealed a papillated epidermis with scattered solitary mononuclearclear cells at all levels of the epidermis and an overlying basket weave orthokeratosis. The cells were epithelioid with increased amphophilic cytoplasm. Immunohistochemical staining was positive for CK7,CEA, and CAM5.2 and negative for S100, CD1a, and Mart-1. These findings were consistent with clear cell papulosis. No treatment was recommended as these lesions were asymptomatic. However, yearlyfollow up was recommended given the resemblance of these cells to those of Paget disease. Review of the literature demonstrates a total of 31 biopsy confirmed cases with AE1, CEA, and EMA positivity and S100negativity as the most consistent staining properties. A recent retrospective review of 19 cases documents long term follow-up of at least six years and up to 21 years. The results suggested a tendency toward selfresolution and an absence of malignant progression, supporting the benign nature of these lesions. PMID- 29469772 TI - Precalcaneal congenital fibrolipomatous hamartoma. AB - Precalcaneal congenital fibrolipomatous hamartoma is a benign condition of infancy that is sometimes misdiagnosed due to lack of reports in the literature. Lesions usually present with painless, non-pruritic, skin colored bilateral, solitary, symmetric nodules located in the middle of the heels. The lesions gradually increase in size and then regress by the age of 2 to3 years old. PMID- 29469773 TI - Adult blaschkolinear acquired inflammatory skin eruption (BLAISE) with simultaneous features of lichen striatus and blaschkitis. AB - Blaschkitis and lichen striatus are generally distinguished in the literature by the age of onset, lesion distribution, and histopathology. However, there is currently no clear consensus among authors about whether to consider blaschkitis and lichen striatus different clinical entities or a spectrum ofthe same disease. We present a case of adult BLAISE with features of both lichen striatus and blaschkitis, which seems to support the theory that these clinical entities may in fact represent a spectrum of the same pathological process. PMID- 29469775 TI - Coexistence of keloids and pilomatricoma in a patient with Rubinstein-Taybi syndrome. AB - Rubinstein-Taybi syndrome (RTS) is an autosomaldominant hereditary disease, which contains many skeletal and organ anomalies as well as mental retardation. Although high incidence of keloids in RTS is known, it is difficult to find a detailed report on the clinical features of keloids. In the following letter, we report an RTS patient fulfilling diagnostic criteria whosuffered from both keloids and pilomatricoma. We also performed a literature search, which identified the possible involvement of the Wnt/beta-catenin signaling pathway in the pathogenesis of these two skin lesions. PMID- 29469776 TI - Phytophotodermatitis related to carrot extract-containing sunscreen. AB - Phytophotodermatitis is a clinical diagnosis from phototoxicity of the skin induced by contact with plants or their extracts. Phytophotodermatitis maypresent with burning, erythema, patches, plaques, vesicles, bullae, or hyperpigmented patches in welldemarcated and unusual shapes. Inquiring about occupation, hobbies, and plant or plant extract contact is essential to establishing the diagnosis. Herein we present a case of phytophotodermatitisafter use of carrot extract-containing sunscreen presenting as a hyperpigmented patch in a geometric distribution with accentuation of pigment within the dynamic rhytides. PMID- 29469777 TI - Hormonal therapies for hidradenitis suppurativa: Review. AB - Hidradenitis suppurativa is a recurrent inflammatory skin condition characterized by abscesses and boils, predominantly in the groin, armpit, and buttocks areas. HS is not a life-threatening condition, but severely impairs quality of life in those affected. Finding a successful treatment approach for HS has been challenging, in part because of the lack of a gold-standard treatment method, limited research-based information, and the nature of clinical variation in the disease. Treatment commonly consists of antibiotics, anti-inflammatory therapy, hormonal therapy, and more invasive clinical procedures. Treatment is chosen by the degree of severity by which the condition presents and is modified accordingly. This review describes the roles of hormones in the pathogenesis of hidradenitis suppurativa and describes the use of hormonal therapy such as, finasteride, dutasteride, spironolactone, and oral contraceptives. The outcomes of the use of these modalities in various clinical studies are summarized. PMID- 29469778 TI - Incorporating social media into dermatologic education. AB - In the current digital age, medical education has slowly evolved from the largely lecture-based teaching style of the past to incorporate more interactive pedagogical techniques, including use of social media. Already used readily by millennial trainees and clinicians, social media can also be used in innovative ways to teach trainees and facilitate continuing education among practicing clinicians. In this commentary, we discuss many learning benefits of social media and review potential pitfalls of employing social media in both trainee and physician dermatological education. PMID- 29469779 TI - Cutaneous infection due to Mycobacterium immunogenum: an European case report and review of the literature. AB - (no more than 200 words): In the last few years, the incidence of cutaneous infections caused by nontuberculous mycobacteria is increasing. Since Mycobacterium immunogenum was first described in 2001, few case reports have been described, all of them in the American continent. We report a case with cutaneous infection caused by this newly discovered NTB in Europe.A 65-year-old woman presented with a 3-months history of pruritic lesions on abdomen. Examination revealed erythematous inflammatory papules, pustules, and crusts. Three weeks later, mycobacteria were cultured from the biopsy specimen. Mycobacterium immunogenum was identified based on susceptibility test results and polymerase chain reaction (PCR) restriction enzyme analysis. Treatment with clarithromycin was started. M. immunogenum is a nontuberculous mycobacterium that was first described by Wilson et al. in 2001 as a rapidly growing variety and new species in the Mycobacterium chelonae-Mycobacterium abscessus group. PCR-restriction analysis of a 439-bp segment of the hsp65 gene and/or sequencing the species specific region of the 16S rDNA can confirm this new species. Since the description of M. immunogenum, 8 clinical case reports have been published, most involving cutaneous infections and all of them in the American continent. We present a case of cutaneous infection caused by M. immunogenum in a Spanish woman. PMID- 29469780 TI - Non-dermatomal varicella-zoster skin infection: disseminated cutaneous herpes zoster without dermatome in an immunosuppressed woman. AB - Disseminated herpes zoster is defined as the presence of more than 20 lesions outside the dermatome. This unusual presentation is more common in immunosuppressed patients. Complications such as hepatitis, encephalitis, and pneumonitis are more likely in individuals with disseminated varicella zoster virus infection.A 63-year-old woman being treated for breast cancer developed multiple pustules and vesicles days after starting doxorubicin and cyclophosphamide chemotherapy. Ten individual lesions appeared on her chest, abdomen, back, and leg. Non-dermatomal disseminated herpes zoster was suspected. She was treated with oral antiviral therapy, as well as with oral and topical antibiotics. Varicella zoster virus infection was confirmed by direct fluorescent antibody staining. After one month, her skin lesions had resolved and she resumed chemotherapy.In a setting of immunosuppression, the rare presentation of disseminated herpes zoster without dermatome should be considered. Appropriate antiviral therapy should be administered while waiting for confirmation of the diagnosis, so as to reduce the risk of visceral dissemination of the varicella zoster virus infection. PMID- 29469781 TI - Ponatinib-induced ichthyosiform drug eruption: insights into acquired ichthyosis. AB - Cutaneous adverse events are commonly experienced with use of tyrosine kinase inhibitors in the treatment of leukemia and typically include nonspecific cutaneous eruptions and xerosis. We report the case of a man who experienced an ichthyosiform drug eruption while taking ponatinib, a third-generation tyrosine kinase inhibitor. Disruption of epidermal growth pathways through inhibition of various receptor tyrosine kinases by ponatinib may offer insights into the pathophysiologic mechanisms behind acquired ichthyosis. PMID- 29469782 TI - Rapidly fatal metastatic cutaneous angiosarcoma initially mimicking a furuncle in a middle-aged male. AB - Cutaneous angiosarcomas are rare but typically occur in three distinct clinical settings and are most commonly found on the scalp or face of elderly men. Positive prognostic factors include tumor size less than 5 cm, primary tumor location below the head, negative margins after excision, resectability, and younger age. Metastases drastically reduce survival and the most common metastatic site is lung. We present a 43-year-old man who had primary cutaneous angiosarcoma that initially mimicked a furuncle and eventuated in multiple metastases. The metastatic disease included brain involvement, which has rarely been reported, especially in a relatively young person without known predisposing conditions. This unique case also highlights the need for early diagnosis followed by advanced imaging, given the limitations of current therapies and high metastatic potential of angiosarcoma. PMID- 29469783 TI - Delayed presentation of toxic epidermal necrolysis-like cutaneous acute graft versus-host disease in the setting of recent immunosuppressant discontinuation. AB - Acute graft-versus-host disease (GvHD) is a process that classically has been defined as occurring less than 100 days after stem cell transplant. When Stage IV cutaneous acute GvHD occurs outside this window, it can be difficult to distinguish clinically from toxic epidermal necrolysis (TEN). A 50-year-old man with diffuse large B-cell lymphoma who had undergone an allogeneic stem cell transplant 20 months previously was admitted for neutropenic septic shock. He developed a slowly progressing macular/papular eruption with multiple tender bullae found to be consistent with TEN-like Stage IV cutaneous acute GvHD on biopsy. It was discovered that the patient's maintenance immunosuppression had been completely discontinued one month prior to admission in preparation for clinical trial enrollment, causing a late presentation of cutaneous acute GvHD. This case provides particular insight into the diagnosis and management of late presenting acute GvHD given that it is the first reported case of Stage IV cutaneous acute GvHD more than 12 months after stem cell transplant. In the setting of decreased immunosuppression in a patient with a history of a stem cell transplant, acute graft-versus-host disease must be considered regardless of the time that has elapsed since transplant. PMID- 29469784 TI - A case of erythema multiforme major following administration of ciprofloxacin ophthalmic drops. AB - A 49-year old woman was hospitalized for generalized rash and pruritus following the administration of ophthalmic drops containing ciprofloxacin to treat conjunctivitis. Physical examination demonstrated diffuse erythematous papules and plaques with a targetoid appearance, injected sclera, and multiple erosions in the oropharynx. Skin biopsy confirmed a diagnosis of erythema multiforme major. The eye drops were discontinued and supportive treatment was initiated; the patient recovered in four weeks and was discharged from the hospital. Although cases such as this are rare, it is important that physicians take a thorough medication history from all patients with suspected erythema multiforme, including topical and ophthalmic medications. Prompt discontinuation of the offending agent can hasten patient recovery and optimize outcomes. PMID- 29469785 TI - Pemphigus foliaceus worsened by drugs in a patient with psoriasis, responding to adalimumab. AB - Pemphigus foliaceus is a blistering autoimmune disease related to the production of autoantibodies against desmoglein 1. We present a patient with psoriasis and pemphigus foliaceus aggravated by enalapril and amlodipine intake, with successful response of both conditions to adalimumab therapy. PMID- 29469786 TI - Primary vulvar Paget disease - the importance of clinical suspicion. AB - Extramammary Paget disease of the vulva is a rare condition that accounts for only 1-2% of vulvar malignancies and represents a frequent cause of misdiagnosis. It is most commonly seen in postmenopausal women. Clinically it is similar to Paget disease of the breast, appearing as red, well-demarcated eczematoid lesions, with slightly raised edges. A high degree of clinical suspicion is very important when evaluating these lesions in order to avoid misdiagnosis and delay of effective treatment. We present a case of vulvar Paget disease treated with vulvectomy. PMID- 29469787 TI - Telangiectasia macularis eruptiva perstans associated with a sicca complex. AB - We present the case of woman in her 50s who developed numerous red-brown telangiectatic macules on her trunk and extremities, as well as persistent dry eyes and dry mouth. Skin biopsy was consistent with telangiectasia macularis eruptiva perstans (TMEP). Serum tryptase was elevated suggesting systemic involvement. Anti-Ro and La were negative. ANA was positive. Salivary gland biopsy revealed a focus score of 3 and immunostains revealed infiltrates of aberrant CD117 positive mast cells. This case suggests a mechanistic role of mastocytosis in salivary compromise. PMID- 29469788 TI - Erythematous asymptomatic nodule on the sole. AB - A 75-year-old man presented to the dermatology clinic with an asymptomatic lesion on his right plantar surface. The lesion had progressively grown for two months. Physical examination revealed an erythematous and slightly scaly nodule measuring 10x10 mm. Dermoscopy examination showed central diffuse erythema with small red globules. A punch-biopsy revealed a proliferation of irregularly branched small vessels with collapsed lumen, extending in an infiltrative pattern in the superficial and deep dermis. Although this is a rare location, a diagnosis of microvenular hemangioma was made. PMID- 29469789 TI - Paquidermodactilia, engrosamiento digital proximal. Pachydermodactyly, digital proximal thickening. AB - We report a case of pachydermodactyly (PDD). PDD is a benign, asymptomatic soft tissue swelling affecting the skin of the lateral aspects of the proximal interphalangeal joints of the fingers, mostly in young adolescent males. It has often been interpreted as a consequence of tic-like behavior as part of an obsessive-compulsive disorder. Although the diagnosis is essentially clinical, skin biopsy shows compact orthokeratotic hyperkeratosis, increased numbers of collagen fibers and fibroblasts, and no inflammatory changes. A rapid clinical recognition of PDD should avoid many unproductive and expensive diagnostic tests. PMID- 29469790 TI - Jessner lymphocytic infiltration - rare in childhood. AB - We present a 13-year-old girl with Jessner lymphocytic infiltrate of the skin, who has suffered from the disease since the age of 9 years. It is a rare disease in childhood, and we highlight the clinical features and therapeutic response of tacrolimus. PMID- 29469791 TI - Hyperkeratotic and hypertrophic lichen nitidus. AB - Lichen nitidus typically presents as shiny pin-head sized papules on the trunk and extremities, often affecting children and young adults. In this prototypical form, it rarely presents a diagnostic challenge being characterized by distinctive clinical and histopathologic findings. We describe a rare variant of lichen nitidus, which we term "hyperkeratotic and hypertrophic lichen nitidus." PMID- 29469792 TI - Kimura disease. AB - Kimura disease is a rare, benign, chronic, immune-mediated inflammatory disorder. We report a 46-year-old man who presented with a cutaneous nodule behind his left ear. Surgical removal of the growth confirmed the histological diagnosis of KD. There was no recurrence found after 3 years follow-up. PMID- 29469793 TI - Lesiones subcutaneas dolorosas en paciente con melanoma metastasico: un caso de paniculitis linfocitica asociado a vemurafenib. AB - Vemurafenib ha probado ser una herramienta util en el tratamiento de melanoma metastasico con mutacion BRAF-V600E. Los efectos adversos incluyen artralgias, fatiga y toxicidad cutanea, siendo infrecuente la paniculitis. Presentamos el caso de una paciente de 43 anos con melanoma metastasico que desarrolla lesiones subcutaneas dolorosas en miembros inferiores y superiores, asociadas a clinica sistemica despues de 2 semanas de inicio de tratamiento con Vemurafenib + Cobimetinib. La histologia demostro paniculitis linfocitaria septal y lobulillar. La paciente tuvo mala tolerancia al tratamiento anti diana a dosis plenas, requiriendo su ajuste, generando una corticodependencia para controlar sintomatologia, y que finalmente obligo a la descontinuacion de la terapia dirigida contra melanoma. A la fecha, se han descrito 29 casos en la literatura de paniculitis asociada a vemurafenib, siendo la mayoria paniculitis neutrofilicas con adecuado control de sintomatologia asociando antiinflamatorios no esteroidales y/o corticoides orales sin requerir en su mayoria modificacion de la terapia contra melanoma; sin embargo hay que tener presente que pueden haber casos con mala evolucion que obligan a la reduccion de dosis de vemurafenib y descontinuar el tratamiento, como ha ocurrido en nuestro reporte.Vemurafenib has proven to be a useful tool in the treatment of metastatic melanoma with BRAF V600E mutation. Adverse effects include arthralgia, fatigue, and skin toxicity; panniculitis is a rare complication. We present the case of a 43-year-old patient with metastatic melanoma who developed painful subcutaneous nodules of the lower and upper limbs and associated systemic clinical symptoms after 2 weeks of treatment with vemurafenib plus cobimetinib. Histology showed a septal and lobular lymphocytic panniculitis.The patient had poor tolerance of the full-dose treatment, requiring its adjustment. Systemic corticosteroids were required to control symptomatology, which finally forced the discontinuation of the medication.To date, 29 cases have been described in the literature of panniculitis associated with vemurafenib. Most of these have been neutrophilic panniculitis, but adequate control of symptoms is usually achieved with nonsteroidal anti-inflammatory drugs and/or oral corticosteroids without requiring modification of melanoma therapy. However, it must be borne in mind that there may be cases that force the reduction and discontinuation ofvemurafenib treatment. We believe that this histological variant of lymphocytic panniculitis and its poor response to decrease in vemurafenib makes this case unusual and instructive. PMID- 29469794 TI - Inflamed actinic keratoses associated with pemetrexed and carboplatin therapy. AB - Eruptive actinic keratosis (AK) consequent to systemic chemotherapy can be confused with drug allergies. We present the first case of inflamed AKs in one patient after receiving combination therapy with pemetrexed and carboplatin.A 68 year-old woman with non-small cell lung adenocarcinoma (NSCLC) presented with numerous pruritic ill-defined, gritty, erythematous papules consistent with AKs on her upper chest, upper back, and arms two weeks after completing the first cycle of combination therapy with carboplatin and pemetrexed. The care team managed her with topical steroids and the lesions resolved within one month. The patient resumed the second cycle of chemotherapy and reported the occurrence of a similar but milder eruption.This case illustrates that eruptive AKs should be considered in the differential diagnosis of drug-related rashes, especially if the physical exam is suggestive. The mainstay of treatment should be directed at symptomatic improvement, and chemotherapy may be continued. PMID- 29469795 TI - Eritema anular eosinofilico en un adulto Eosinophilic anular erythema in an adult. AB - Eosinophilic annular erythema (EAE) is an uncommon eosinophilic dermatosis. Clinically it is characterized by recurrent episodes of annular or figurative plaques. The histopathological study shows a perivascular inflammatory infiltrate in the superficial and deep dermis, composed of lymphocytes and eosinophils. It was originally described in children. We report an adult woman who presented with recurrent erythematous annular plaques on the trunk and extremities. A biopsy showed a mainly perivascular lymphocytic infiltrate with numerous eosinophils in the dermis. Laboratory examinations revealed subclinical hypothyroidism. The lesions resolved with topical corticosteroid spontaneously after 3 months. PMID- 29469796 TI - Trends in unsolicited dermatologic opinions: a national survey. AB - In dermatology, a particularly common ethical dilemma can arise when the skin lesions of bystanders are inadvertently viewed in public settings. Dermatology is a unique field, where a person's organ of interest is readily visible to others. When lesions are suspicious for skin disease, unsolicited medical opinions may or may not be given depending on several factors. This study examined the actions and attitudes of dermatologists with different levels of experience through the use of case scenarios with various settings and skin lesions. PMID- 29469797 TI - A gastronomic delight? AB - Flagellate dermatitis (FD) exhibits a striking clinical appearance similar to whiplash marks. General dermatologists are likely to encounter this clinical appearance as a more localized presentation of phytophotodermatosis. Jellyfish stings may also cause localized linear or FD. Chemotherapeutic agents such as bleomycin, doxorubicin, docetaxel, and trastuzumab are well-recognized causes of a widespread FD and it may more rarely be seen in connective tissue disease such as dermatomyositis or Still disease. In our case, this was a presentation of shiitake mushroom dermatitis. PMID- 29469798 TI - Complete resolution of erythema elevatum diutinum using oral sulfasalazine. AB - Erythema elevatum diutinum (EED) is a rare, chronic small-vessel vasculitis that presents as firm, red, violaceous, or brown papules and nodules on the extensor surfaces of the limbs. Oral dapsone is considered first-line therapy for EED; in the current case report, a patient presenting with EED began dapsone treatment and symptoms subsided within two weeks. Seven months later, the patient became pregnant and stopped dapsone owing to her concerns with dapsone use during pregnancy, resulting in recurrence of EED symptoms. We present a novel treatment approach with oral sulfasalazine, which was given to the patient in lieu of dapsone and resulted in complete resolution of EED symptoms. PMID- 29469799 TI - Complete response of secukinumab in palmoplantar psoriasis. AB - Palmoplantar psoriasis is plaque psoriasis involving the palms and soles. Palmoplantar psoriasis is a treatment challenge for dermatologists and it is difficult to treat with topical and systemic therapies. Owing to its location and manifestations, palmoplantar psoriasis is associated with greater pain, functional limitations, and significant impairment of health-related quality of life. Recently a new biologic agent, secukinumab, has been approved for treatment of moderate to severe plaque psoriasis. GESTURE trial is a study of the secukinumab clinical development that evaluates efficacy and safety in this subpopulation of patients. We present a patient with palmar psoriasis refractory to systemic treatments who showed a gradual and complete response to secukinumab sustained at week 30 and without adverse events. Our patient had a significant improvement in his quality of life and work activity. PMID- 29469800 TI - Analysis of population inquiry on practices for ultraviolet radiation protection. AB - UV radiation exposure is one of the key modifiable risk factors for skin cancer. Hence, patient education regarding skin protection and sunscreen use is of tremendous importance to public health. To better understand patient practices regarding skin protection in a population level, we looked into the Internet search behavior of the US-based population. We investigated patient inquires on the United States Food and Drug Administration (FDA) announcements regarding sunscreen use by quantifying search terms such as "broad spectrum sunscreen", "sunscreen" and "sunblock" with Google Trends, a novel methodology for understanding internet search practices. Our findings show that "broad spectrum sunscreen" searches were significantly increased post 2011 FDA announcements, which suggest increased public awareness regarding the importance of broad spectrum protection. It is encouraging these preliminary results indicate that skin protection practices are being increasingly investigated by the general public and may serve as a novel approach for identifying areas of improvement regarding patient education on the reduction of the risk for skin cancer. PMID- 29469801 TI - Undisturbed characteristic herpes simplex virus 2 outbreak. AB - Herpes simplex virus 2 (HSV-2) is a common sexually transmitted disease that typically presents with focal erosions or small vesicles on an erythematous base.Herein, a case is described in which a 42-year old man experienced a genital HSV-2 outbreak after sustaining a spinal cord injury. No typical prodromal symptomswere experienced; therefore the vesicular lesions remained completely intact, granting an unusual opportunity to visualize herpetic infection in its most classic morphology. PMID- 29469802 TI - Nail or plate in the management of distal extra-articular tibial fracture, what is better? Valutation of outcomes. AB - INTRODUCTION: Distal tibial fractures are the most common long bone fractures. Several studies focusing on the methods of treatment of displaced distal tibial fractures have been published. To date, locked plates, intramedullary nails and external fixation are the three most used techniques. The aim of our study was to compare intramedullary nail (IMN) and locked plate (LP) for treatment of this kind of fracture. MATERIALS AND METHODS: We collected data on 81 patients with distal tibial fractures (distance from the joint between 40 and 100 mm) and we divided into two groups: IMN and LP. We compared in the 2 groups the mean operation time, the mean union time, the infection rate the rate of malunion and nonunion, the full weight bearing time. RESULTS: No patient in the two groups developed a nonunion. None of the patients obtained a fair or poor outcome. Overall 52 patients obtained an excellent result (69.3%) and 23 obtained a good result (30.6%). DISCUSSION: Our study results indicate a superiority of IMN over LP in terms of lower rates of infections and statistically significant shorter time to full weight bearing. Whereas LP appeared to be advantageous over IMN in terms of leading to a better anatomical and fixed reductions of the fracture and a lower rate of union complications. The two treatments achieved comparable results in terms of operation time, hospital stay, union time and functional outcomes. PMID- 29469803 TI - Use of the HemiCAP partial hip resurfacing technique for traumatic femoral head osteochondral defects following obturator hip dislocations. AB - Fracture of the femoral head (OTA 31-C1.3) following anterior obturator dislocations are a challenging problem as the fractures are often communited, impacted and with loose osteochondral fragments, making surgical fixation difficult. This can result in residual articular defects if the fragments cannot be internally fixed and need be excised, predisposing to secondary osteoarthritis. Treatment options for these defects are limited, have variable results and with limited literature to guide us on outcomes due to the rarity of these injuries. Here, we describe the first use of the technique of partial femoral head resurfacing in two patients with such fractures and report on their long term outcomes. PMID- 29469804 TI - Early results of total hip arthroplasty using dual-mobility cup in patients with osteonecrosis of the femoral head. AB - INTRODUCTION: Osteonecrosis of the femoral head (ONFH) remains a therapeutic challenge for patients undergoing total hip arthroplasty (THA). The majority of these patients are young with high functional demand, and show an increased risk of dislocation following surgery than patients with osteoarthritis. The use of double mobility cup (DMC) has been linked with lower rates of complications when compared to conservative cups; however, the literature is scarce over DMC results in patients with ONFH. The aim of the study is to report the early outcomes of patients with ONFH treated with THA-DMC. MATERIALS: A retrospective analysis of patients suffering from ONFH who underwent THA using DMC (THA-DMC) from 2006 to 2015 were evaluated for functional status and risk of post-operative complications. Thirty THA-DMC in 26 patients with a mean follow-up of 51 months were evaluated clinically (modified Hip Harris Score) and radiologically. RESULTS: The mean age of the included patients was 54.9 years. At final follow up, the mean modified Hip Harris score was 98.7 +/- 2.7 and no dislocation episodes or revision surgeries were recorded. The radiological assessment revealed no signs of migration/tilting, radiolucent lines, periprosthetic osteolysis or heterotopic ossification over the DMC component and the femoral stem. The survival rate over 51 months of follow-up was 100%. DISCUSSION: The use of the new generation of dual mobility cup in patients with ONFH showed excellent functional early results with no major complications such as dislocation. PMID- 29469805 TI - C/EBPdelta drives interactions between human MAIT cells and endothelial cells that are important for extravasation. AB - Many mediators and regulators of extravasation by bona fide human memory phenotype T cells remain undefined. Mucosal-associated invariant T (MAIT) cells are innate-like, antibacterial cells that we found excelled at crossing inflamed endothelium. They displayed abundant selectin ligands, with high expression of FUT7 and ST3GAL4, and expressed CCR6, CCR5, and CCR2, which played non-redundant roles in trafficking on activated endothelial cells. MAIT cells selectively expressed CCAAT/enhancer-binding protein delta (C/EBPdelta). Knockdown of C/EBPdelta diminished expression of FUT7, ST3GAL4 and CCR6, decreasing MAIT cell rolling and arrest, and consequently the cells' ability to cross an endothelial monolayer in vitro and extravasate in mice. Nonetheless, knockdown of C/EBPdelta did not affect CCR2, which was important for the step of transendothelial migration. Thus, MAIT cells demonstrate a program for extravasastion that includes, in part, C/EBPdelta and C/EBPdelta-regulated genes, and that could be used to enhance, or targeted to inhibit T cell recruitment into inflamed tissue. PMID- 29469806 TI - MreB filaments align along greatest principal membrane curvature to orient cell wall synthesis. AB - MreB is essential for rod shape in many bacteria. Membrane-associated MreB filaments move around the rod circumference, helping to insert cell wall in the radial direction to reinforce rod shape. To understand how oriented MreB motion arises, we altered the shape of Bacillus subtilis. MreB motion is isotropic in round cells, and orientation is restored when rod shape is externally imposed. Stationary filaments orient within protoplasts, and purified MreB tubulates liposomes in vitro, orienting within tubes. Together, this demonstrates MreB orients along the greatest principal membrane curvature, a conclusion supported with biophysical modeling. We observed that spherical cells regenerate into rods in a local, self-reinforcing manner: rapidly propagating rods emerge from small bulges, exhibiting oriented MreB motion. We propose that the coupling of MreB filament alignment to shape-reinforcing peptidoglycan synthesis creates a locally acting, self-organizing mechanism allowing the rapid establishment and stable maintenance of emergent rod shape. PMID- 29469807 TI - GRAM domain proteins specialize functionally distinct ER-PM contact sites in human cells. AB - Endoplasmic reticulum (ER) membrane contact sites (MCSs) are crucial regulatory hubs in cells, playing roles in signaling, organelle dynamics, and ion and lipid homeostasis. Previous work demonstrated that the highly conserved yeast Ltc/Lam sterol transporters localize and function at ER MCSs. Our analysis of the human family members, GRAMD1a and GRAMD2a, demonstrates that they are ER-PM MCS proteins, which mark separate regions of the plasma membrane (PM) and perform distinct functions in vivo. GRAMD2a, but not GRAMD1a, co-localizes with the E Syt2/3 tethers at ER-PM contacts in a PIP lipid-dependent manner and pre-marks the subset of PI(4,5)P2-enriched ER-PM MCSs utilized for STIM1 recruitment. Data from an analysis of cells lacking GRAMD2a suggest that it is an organizer of ER PM MCSs with pleiotropic functions including calcium homeostasis. Thus, our data demonstrate the existence of multiple ER-PM domains in human cells that are functionally specialized by GRAM-domain containing proteins. PMID- 29469810 TI - Design and analysis of coiled fiber reinforced soft pneumatic actuator. AB - Fiber reinforced elastomeric enclosures (FREEs) are soft pneumatic actuators that can contract and generate forces upon pressurization. Typical engineering applications utilize FREEs in their straight cylindrical configuration and derive actuation displacement and forces from their ends. However, there are several instances in nature, such as an elephant trunk, snakes and grapevine tendrils, where a spiral configuration of muscle systems is used for gripping, thereby establishing a mechanical connection with uniform force distribution. Inspired by these examples, this paper investigates the constricting behavior of a contracting FREE actuator deployed in a spiral or coiled configuration around a cylindrical object. Force balance is used to model the blocked force of the FREE, which is then related to the constriction force using a string model. The modeling and experimental findings reveal an attenuation in the blocked force, and thus the constriction force caused by the coupling of peripheral contact forces acting in the spiral configuration. The usefulness of the coiled FREE configuration is demonstrated in a soft arm orthosis for crutch users that provides a constriction force around the forearm. This design minimizes injury risk by reducing wrist load and improving wrist posture. PMID- 29469808 TI - Rab5 and Alsin regulate stress-activated cytoprotective signaling on mitochondria. AB - Mitochondrial stress response is essential for cell survival, and damaged mitochondria are a hallmark of neurodegenerative diseases. Thus, it is fundamental to understand how mitochondria relay information within the cell. Here, by investigating mitochondrial-endosomal contact sites we made the surprising observation that the small GTPase Rab5 translocates from early endosomes to mitochondria upon oxidative stress. This process is reversible and accompanied by an increase in Rab5-positive endosomes in contact with mitochondria. Interestingly, activation of Rab5 on mitochondria depends on the Rab5-GEF ALS2/Alsin, encoded by a gene mutated in amyotrophic lateral sclerosis (ALS). Alsin-deficient human-induced pluripotent stem cell-derived spinal motor neurons are defective in relocating Rab5 to mitochondria and display increased susceptibility to oxidative stress. These findings define a novel pathway whereby Alsin catalyzes the assembly of the Rab5 endocytic machinery on mitochondria. Defects in stress-sensing by endosomes could be crucial for mitochondrial quality control during the onset of ALS. PMID- 29469811 TI - Evaluating the Laplace pressure of water nanodroplets from simulations. AB - We calculate the components of the microscopic pressure tensor as a function of radial distance r from the centre of a spherical water droplet, modelled using the TIP4P/2005 potential. To do so, we modify a coarse-graining method for calculating the microscopic pressure (Ikeshoji et al 2003 Mol. Simul. 29 101) in order to apply it to a rigid molecular model of water. As test cases, we study nanodroplets ranging in size from 776 to 2880 molecules at 220 K. Beneath a surface region comprising approximately two molecular layers, the pressure tensor becomes approximately isotropic and constant with r. We find that the dependence of the pressure on droplet radius is that expected from the Young-Laplace equation, despite the small size of the droplets. PMID- 29469809 TI - Efficient and accurate extraction of in vivo calcium signals from microendoscopic video data. AB - In vivo calcium imaging through microendoscopic lenses enables imaging of previously inaccessible neuronal populations deep within the brains of freely moving animals. However, it is computationally challenging to extract single neuronal activity from microendoscopic data, because of the very large background fluctuations and high spatial overlaps intrinsic to this recording modality. Here, we describe a new constrained matrix factorization approach to accurately separate the background and then demix and denoise the neuronal signals of interest. We compared the proposed method against previous independent components analysis and constrained nonnegative matrix factorization approaches. On both simulated and experimental data recorded from mice, our method substantially improved the quality of extracted cellular signals and detected more well isolated neural signals, especially in noisy data regimes. These advances can in turn significantly enhance the statistical power of downstream analyses, and ultimately improve scientific conclusions derived from microendoscopic data. PMID- 29469812 TI - Dimethyl methylphosphonate adsorption and decomposition on MoO2 as studied by ambient pressure x-ray photoelectron spectroscopy and DFT calculations. AB - Organophosphonates range in their toxicity and are used as pesticides, herbicides, and chemical warfare agents (CWAs). Few laboratories are equipped to handle the most toxic molecules, thus simulants such as dimethyl methylphosphonate (DMMP), are used as a first step in studying adsorption and reactivity on materials. Benchmarked by combined experimental and theoretical studies of simulants, calculations offer an opportunity to understand how molecular interactions with a surface changes upon using a CWA. However, most calculations of DMMP and CWAs on surfaces are limited to adsorption studies on clusters of atoms, which may differ markedly from the behavior on bulk solid state materials with extended surfaces. We have benchmarked our solid-state periodic calculations of DMMP adsorption and reactivity on MoO2 with ambient pressure x-ray photoelectron spectroscopy studies (APXPS). DMMP is found to interact strongly with a MoO2 film, a model system for the MoO x component in the ASZM-TEDA(c) gas filtration material. Density functional theory modeling of several adsorption and decomposition mechanisms assist the assignment of APXPS peaks. Our results show that some of the adsorbed DMMP decomposes, with all the products remaining on the surface. The rigorous calculations benchmarked with experiments pave a path to reliable and predictive theoretical studies of CWA interactions with surfaces. PMID- 29469813 TI - The W alloying effect on thermal stability and hardening of nanostructured Cu-W alloyed thin films. AB - In order to achieve desired mechanical properties of alloys by manipulating grain boundaries (GBs) via solute decoration, it is of great significance to understand the underlying mechanisms of microstructural evolution and plastic deformation. In this work, nanocrystalline (NC) Cu-W alloyed films with W concentrations spanning from 0 to 40 at% were prepared by using magnetron sputtering. Thermal stability (within the temperature range of 200 degrees C-600 degrees C) and hardness of the films were investigated by using the x-ray diffraction, transmission electron microscope (TEM) and nanoindentation, respectively. The NC pure Cu film exhibited substantial grain growth upon all annealing temperatures. The Cu-W alloyed films, however, displayed distinct microstructural evolution that depended not only on the W concentration but also on the annealing temperature. At a low temperature of 200 degrees C, all the Cu-W alloyed films were highly stable, with unconspicuous change in grain sizes. At high temperatures of 400 degrees C and 600 degrees C, the microstructural evolution was greatly controlled by the W concentrations. The Cu-W films with low W concentration manifested abnormal grain growth (AGG), while the ones with high W concentrations showed phase separation. TEM observations unveiled that the AGG in the Cu-W alloyed thin films was rationalized by GB migration. Nanoindentation results showed that, although the hardness of both the as-deposited and annealed Cu-W alloyed thin films monotonically increased with W concentrations, a transition from annealing hardening to annealing softening was interestingly observed at the critical W addition of ~25 at%. It was further revealed that an enhanced GB segregation associated with detwinning was responsible for the annealing hardening, while a reduced solid solution hardening for the annealing softening. PMID- 29469814 TI - Bifunctional bamboo-like CoSe2 arrays for high-performance asymmetric supercapacitor and electrocatalytic oxygen evolution. AB - Bifunctional bamboo-like CoSe2 arrays are synthesized by thermal annealing of Co(CO3)0.5OH grown on carbon cloth in Se atmosphere. The CoSe2 arrays obtained have excellent electrical conductivity, larger electrochemical active surface areas, and can directly serve as a binder-free electrode for supercapacitors and the oxygen evolution reaction (OER). When tested as a supercapacitor electrode, the CoSe2 delivers a higher specific capacitance (544.6 F g-1 at current density of 1 mA cm-2) compared with CoO (308.2 F g-1) or Co3O4 (201.4 F g-1). In addition, the CoSe2 electrode possesses excellent cycling stability. An asymmetric supercapacitor (ASC) is also assembled based on bamboo-like CoSe2 as a positive electrode and active carbon as a negative electrode in a 3.0 M KOH aqueous electrolyte. Owing to the unique stucture and good electrochemical performance of bamboo-like CoSe2, the as-assembled ACS can achieve a maximum operating voltage window of 1.7 V, a high energy density of 20.2 Wh kg-1 at a power density of 144.1 W kg-1, and an outstanding cyclic stability. As the catalyst for the OER, the CoSe2 exhibits a lower potential of 1.55 V (versus RHE) at current density of 10 mA cm-2, a smaller Tafel slope of 62.5 mV dec-1 and an also outstanding stability.

AB - The modification of the local structure in cubic perovskite KTaO3 irradiated with 3 MeV and 1.1 GeV Au ions is studied by Raman and x-ray absorption spectroscopy, complemented by density functional theory (DFT) calculations. In the case of irradiation with 3 MeV Au ions where displacement cascade processes are dominant, the Ta L3-edge x-ray absorption measurements suggest that a peak corresponding to the Ta-O bonds in the TaO6 octahedra splits, which is attributed to the formation of TaK antisite defects that are coupled with oxygen vacancies, V O. This finding is consistent with the DFT calculations. Under irradiation with 1.1 GeV ions, the intense ionization and electronic energy deposition lead to a blue shift and an intensity reduction of active Raman bands. In the case of sequential irradiations, extended x-ray absorption fine structure measurements reveal a decrease in concentration of coupled TaK-V O defects under subsequent irradiation with 1.1 GeV Au ions.

AB - White light emitting diodes (WLEDs) based on quantum dots (QDs) are emerging as robust candidates for white light sources, however they are suffering from the problem of energy loss resulting from the re-absorption and self-absorption among the employed QDs of different peak wavelengths. It still remains a challenging task to construct WLEDs based on single-phase QD emitters. Here, CdS QDs with short synthesis times are introduced to the fabrication of WLEDs. With a short synthesis time, on one hand, CdS QDs with a small diameter with blue emission can be obtained. On the other hand, surface reconstruction barely has time to occur, and the surface is likely defect-ridden, which enables the existence of a broad emission covering the range of green, yellow and red regions. This is essential for the white light emission of CdS QDs, and is very important for WLED applications. The temporal evolution of the PL spectra for CdS QDs was obtained to investigate the influence of growth time on the luminescent properties. The CdS QDs with a growth time of 0.5 min exhibited a colour rendering index (CRI) of 79.5 and a correlated colour temperature (CCT) of 6238 K. With increasing reaction time, the colour coordinates of the CdS QDs will move away from the white light region in the CIE 1931 chromaticity diagram. By integrating the as prepared white light emission CdS QDs with a violet GaN chip, WLEDs were fabricated. The fabricated WLEDs exhibited a CRI of 87.9 and a CCT of 4619 K, which satisfy the demand of general illumination. The luminous flux and the luminous efficiency of the fabricated WLEDs, being less advanced than current commercial white light sources, can be further improved, meaning there is a need for much more in-depth studies on white light emission CdS QDs.

AB - OBJECTIVE: Patients with systemic sclerosis (SSc) experience significant morbidity and mortality, therefore, the development of tests to aid its early diagnosis are very important. The aim of this pilot study was to assess the diagnostic value of novel optical non-invasive skin fluorescence spectroscopy (FS) and tissue oxygen saturation (TOS) viability measurements in patients with established SSc. APPROACH: Two groups were studied, comprising 14 SSc patients and nine healthy controls (93% and 73% females, respectively). FS and TOS measurements were collected from three body sites: the forearm, chest, and calf. Fluorescence intensities at wavelengths attributed to collagen, elastin, and L tryptophan were computed, with adjustment for melanin, and a normalised combined fluorescence score (NCFS) was determined. MAIN RESULTS: The NCFS was significantly higher (p < 0.001) and the combined TOS significantly lower (p < 0.001) in the SSc group. TOS measurements alone showed good classification accuracy (95.7%) at separating SSc from healthy control participants, with some clustering of values close to the 50% oxygenation level in both groups. When the composition and viability measures were combined and modelled using binary logistic regression, excellent results for the sample were obtained following leave one out cross validation (100%). SIGNIFICANCE: The results of this pilot study demonstrate the potential diagnostic utility of FS and TOS assessments in SSc patients and further work is now needed to validate these techniques prospectively in a larger group of SSc patients across the spectrum of the disease, and also patients with other types of vasculopathy and conditions that can cause skin fibrosis. PMID- 29469818 TI - Multi-band magnetotransport in exfoliated thin films of Cu x Bi2Se3. AB - We report magnetotransport studies in thin (<100 nm) exfoliated films of Cu x Bi2Se3 and we detect an unusual electronic transition at low temperatures. Bulk crystals show weak superconductivity with [Formula: see text] K and a possible electronic phase transition around 200 K. Following exfoliation, superconductivity is supressed and a strongly temperature dependent multi-band conductivity is observed for T < 30 K. This transition between competing conducting channels may be enhanced due to the presence of electronic ordering, and could be affected by the presence of an effective internal stress due to Cu intercalation. By fitting to the weak antilocalisation conductivity correction at low magnetic fields we confirm that the low temperature regime maintains a quantum phase coherence length [Formula: see text] nm indicating the presence of topologically protected surface states. PMID- 29469819 TI - The Long Noncoding RNA HOTAIR in Breast Cancer: Does Autophagy Play a Role? AB - HOTAIR (HOX transcript antisense RNA) plays a critical role in chromatin dynamics through the interaction with histone modifiers resulting in transcriptional gene silencing. The promoter of the HOTAIR gene contains multiple estrogen response elements (EREs) and is transcriptionally activated by estradiol in estrogen receptor-positive breast cancer cells. HOTAIR competes with BRCA1, a critical protein in breast cancer and is a critical regulator of genes involved in epithelial-to-mesenchymal transition. It mediates an oncogenic action of c-Myc, essential for breast carcinogenesis. The carcinogenic action of HOTAIR was confirmed in breast cancer stem-like cells, in which it was essential for self renewal and proliferation. Several miRNAs regulate the expression of HOTAIR and HOTAIR interacts with many miRNAs to support cancer transformation. Many studies point at miR-34a as a major component of HOTAIR-miRNAs-cancer cross-talk. The most important role of HOTAIR can be attributed to cancer progression as its overexpression stimulates invasion and metastasis. HOTAIR can regulate autophagy, important for breast cancer cells survival, through the interaction with miRNAs specific for autophagy genes and directly with these genes. The role of HOTAIR mediated autophagy in breast cancer progression can be underlined by its interaction with matrix metalloproteinases, essential for cancer invasion, and beta-catenin can be important for this interaction. Therefore, there are several mechanisms of the interplay between HOTAIR and autophagy important for breast cancer, but further studies are needed to determine more details of this interplay. PMID- 29469820 TI - The Unexpected Tuners: Are LncRNAs Regulating Host Translation during Infections? AB - Pathogenic bacteria produce powerful virulent factors, such as pore-forming toxins, that promote their survival and cause serious damage to the host. Host cells reply to membrane stresses and ionic imbalance by modifying gene expression at the epigenetic, transcriptional and translational level, to recover from the toxin attack. The fact that the majority of the human transcriptome encodes for non-coding RNAs (ncRNAs) raises the question: do host cells deploy non-coding transcripts to rapidly control the most energy-consuming process in cells-i.e., host translation-to counteract the infection? Here, we discuss the intriguing possibility that membrane-damaging toxins induce, in the host, the expression of toxin-specific long non-coding RNAs (lncRNAs), which act as sponges for other molecules, encoding small peptides or binding target mRNAs to depress their translation efficiency. Unravelling the function of host-produced lncRNAs upon bacterial infection or membrane damage requires an improved understanding of host lncRNA expression patterns, their association with polysomes and their function during this stress. This field of investigation holds a unique opportunity to reveal unpredicted scenarios and novel approaches to counteract antibiotic resistant infections.

AB - At the forefront of global development, the chemical industry is being confronted by a growing demand for products and services, but also the need to provide these in a manner that is sustainable in the long-term. In facing this challenge, the industry is being revolutionised by advances in catalysis that allow chemical transformations to be performed in a more efficient and economical manner. To this end, molecular design, facilitated by detailed theoretical and empirical studies, has played a pivotal role in creating highly-active and selective heterogeneous catalysts. In this review, the industrially-relevant Beckmann rearrangement is presented as an exemplar of how judicious characterisation and ab initio experiments can be used to understand and optimise nanoporous materials for sustainable catalysis. PMID- 29469825 TI - Performance analysis of an optical self-interference cancellation system with a directly modulated laser-based demonstration. AB - In this paper, two main performance indices of the optical self-interference cancellation (OSIC) system are theoretically analyzed: cancellation bandwidth and depth. Delay deviation is investigated to be the determining factor of cancellation bandwidth, based on which the bandwidth advantage of the OSIC system over electrical schemes is also proven theoretically. Cancellation depth in the narrowband is mostly influenced by attenuation and delay-adjusting deviation, while in the broadband case, the performance is mostly limited by frequency dependent amplitude and phase mismatch. The cancellation performance analysis is suitable for most linear modulation-demodulation OSIC systems, including the directly modulated laser (DML)-based OSIC system verified experimentally in this paper. The cancellation model is well demonstrated by the agreement between experimental cancellation results and predicted performance. For over-the-air demonstration with the employment of antennas, broadband cancellation within 450 MHz bandwidth of 22 dB and 25 dB is achieved at 900 MHz and 2.4 GHz, respectively. In addition, orthogonal frequency division multiplexing signals are employed to show in-band full-duplex transmission with good performance by the DML-based OSIC system, with successful suppression of self-interference and recovery of the signal of interest. PMID- 29469826 TI - Er-doped Q-switched fiber laser with a black phosphorus/polymethyl methacrylate saturable absorber. AB - A stable Q-switched Er-doped fiber (EDF) laser is successfully obtained by using a black phosphorus (BP)/polymethyl methacrylate (PMMA) film as the saturable absorber (SA). To avoid the oxidization of nanomaterials, the BP nanoparticles are fabricated via a liquid-phase exfoliation method and then embedded into a PMMA film that possesses excellent optical transparency in the selected spectrum range. The modulation depth (MD) of the BP/PMMA film SA is 14.3% and the saturable intensity (Isat) is 6.9 MW/cm2. By inserting the BP/PMMA film into the EDF laser cavity, we achieve the stable passive Q-switching operation over the wavelength range from 1561.21 nm to 1564.16 nm. The repetition rate increases from 10.348 kHz to 30.098 kHz, and the pulse duration decreases from 25.01 MUs to 2.98 MUs by altering the pump power from 9 mW to 90 mW. The maximum single pulse energy is 283.91 nJ. To the best of our knowledge, 283.91 nJ is the largest single pulse energy among the Q-switched fiber lasers with BP as the Q-switcher at the 1.5 MUm wavelength region. The experimental results evidently show that the BP/PMMA film SA can work as a promising Q-switcher for large pulse energy fiber lasers. PMID- 29469822 TI - Autosomal recessive Noonan syndrome associated with biallelic LZTR1 variants. AB - PURPOSE: To characterize the molecular genetics of autosomal recessive Noonan syndrome. METHODS: Families underwent phenotyping for features of Noonan syndrome in children and their parents. Two multiplex families underwent linkage analysis. Exome, genome, or multigene panel sequencing was used to identify variants. The molecular consequences of observed splice variants were evaluated by reverse transcription polymerase chain reaction. RESULTS: Twelve families with a total of 23 affected children with features of Noonan syndrome were evaluated. The phenotypic range included mildly affected patients, but it was lethal in some, with cardiac disease and leukemia. All of the parents were unaffected. Linkage analysis using a recessive model supported a candidate region in chromosome 22q11, which includes LZTR1, previously shown to harbor mutations in patients with Noonan syndrome inherited in a dominant pattern. Sequencing analyses of 21 live-born patients and a stillbirth identified biallelic pathogenic variants in LZTR1, including putative loss-of-function, missense, and canonical and noncanonical splicing variants in the affected children, with heterozygous, clinically unaffected parents and heterozygous or normal genotypes in unaffected siblings. CONCLUSION: These clinical and genetic data confirm the existence of a form of Noonan syndrome that is inherited in an autosomal recessive pattern and identify biallelic mutations in LZTR1. PMID- 29469827 TI - Investigations on surface morphology and bandgap engineering of single crystal boron-doped silicon irradiated by a nanosecond laser. AB - We irradiate the single crystal boron-doped silicon (Si) at various laser fluences with 100 laser shots in ambient air at room temperature using an Nd:YAG laser and investigate its surface morphology and optical properties. The optical microscopy gives evidence of the formation of a crater and reveals that the heat affected zone and melted area are increased with increase in laser fluence from 1.1 to 15.4 J/cm2. The micrographs obtained by scanning electron microscopy (SEM) show that the micro- and nano-structures such as microcracks, bubbles, nucleation sites, clusters, redeposited layered material, nanoparticles, and alike water droplet structures are formed on a laser-exposed Si surface. The optical profilometry of the irradiated Si further confirms the ablation and redeposition of the material and shows that the depth of the crater is increased from 12.1 to 15.2 MUm with increase in fluence from 1.1 to 15.4 J/cm2. Raman spectroscopy of the samples shows that the irradiation generates anneal effects due to higher temperature, which increases the crystallinity of the Si. The ellipsometric analysis shows that the irradiation of Si with increasing laser fluence changes its optical constants (refractive index and extinction coefficient), which further influence its optical properties, e.g., reflectivity, absorptivity, and energy bandgap. The absorptivity of laser irradiated Si tends to increase with increasing laser fluence, and the energy bandgap is decreased accordingly due to increase in structural disorders. Our study shows that the controlled laser irradiation can tune the energy bandgap of exposed Si, and it makes the Si materials useful for the fabrication of optoelectronic devices such as solar cells, photovoltaic cells, and LEDs. PMID- 29469828 TI - Non-contact XUV metrology of Ru/B4C multilayer optics by means of Hartmann wavefront analysis. AB - Short-wavelength imaging, spectroscopy, and lithography scale down the characteristic length-scale to nanometers. This poses tight constraints on the optics finishing tolerances, which is often difficult to characterize. Indeed, even a tiny surface defect degrades the reflectivity and spatial projection of such optics. In this study, we demonstrate experimentally that a Hartmann wavefront sensor for extreme ultraviolet (XUV) wavelengths is an effective non contact analytical method for inspecting the surface of multilayer optics. The experiment was carried out in a tabletop laboratory using a high-order harmonic generation as an XUV source. The wavefront sensor was used to measure the wavefront errors after the reflection of the XUV beam on a spherical Ru/B4C multilayer mirror, scanning a large surface of approximately 40 mm in diameter. The results showed that the technique detects the aberrations in the nanometer range.

AB - In this paper, quantitative experiments were made to measure the concentration of key intermediate products (CO, N2O, and NO) and the gas temperature for combustion flow based on near-infrared and mid-infrared laser absorption spectroscopy. This paper used the developed diagnostic system to study two main ignition modes of a real 1-Newton thruster based on ammonium dinitramide (ADN): steady-state firing and pulse-mode firing over a feed pressure of 5-12 bar. The steady-state firing experiments distinguished the whole process into catalytic decomposition stage and combustion stage, experimentally demonstrating the combustion kinetics mechanism of an ADN monopropellant. Experiments for pulse mode firing showed the measured multispecies concentration and temperature were consistent with pulse trains, verifying good performance for the thruster pulse mode firing operation. The performance of the thruster was given based on the optical measurements, and characteristic velocity for the ADN-based thruster standard operation was higher than the corresponding 1-Newton hydrazine thruster. PMID- 29469830 TI - Space-inhomogeneous phase modulation of laser radiation in an electro-optical ferroelectric liquid crystal cell for suppressing speckle noise. AB - Spatially inhomogeneous modulation of a phase delay with the depth of the order pi or more makes it possible to destroy phase relations in a laser beam passing through an electro-optical cell with the ferroelectric liquid crystal (FLC) and, as a consequence, to suppress speckle noise in images formed by this beam. Such a modulation is a consequence of chaotic changes in the position of the scattering indicatrix of helix-free FLC, when an electro-optical cell is simultaneously supplied with a low-frequency and high-frequency bipolar control voltage. In this work, the phase modulation and effective suppressing of the speckles are realized using a new type of helix-free FLC material with periodic deformations of smectic layers.

AB - This paper proposes a wide color gamut approach that uses white and emerald lighting units as the backlight of the liquid crystal display. The white and emerald backlights are controlled by the image to be displayed. The mixing ratio of the white and the emerald lighting is analyzed so that the maximal color gamut coverage ratio can be achieved. Experimental results prove the effectiveness of the wide color gamut approach using white and emerald backlights. PMID- 29469832 TI - Upconversion luminescence of Ba3La(PO4)3:Yb3+-Er3+/Tm3+ phosphors for optimal temperature sensing. AB - To explore new upconversion (UC) luminescent materials for optical temperature sensing, a series of Ba3La1-x(PO4)3:0.1Yb3+,xEr3+ (abbreviated as BLP:0.1Yb3+, xEr3+, 0.01<=x<=0.03) and Ba3La1-y(PO4)3:0.1Yb3+,yTm3+ (abbreviated as BLP:0.1Yb3+, yTm3+, 0.005<=y<=0.015) phosphors was designed. For Yb3+-Er3+ codoped BLP, the UC emission spectra exhibit a gradual enhancement with increasing pump power, and two-photon process for the green and red emissions of Er3+ has been confirmed by studying the dependence of UC emission intensities on excitation power. When the temperature rises, the fluorescence intensity ratio (FIR) for the H11/22-4I15/2 and S3/24-4I15/2 emissions of Er3+ increases gradually due to the thermalization of populations at the H11/22 and S3/24 levels. With the temperature increased, the absolute sensitivity (SA) shows a continuous increase and reaches about 4.38*10-3 K-1 at 498 K, but the relative sensitivity (SR) decreases gradually. For Yb3+-Tm3+ codoped BLP, the emission intensity of Tm3+ shows a gradual decrease with increasing Tm3+ concentration. By studying the temperature dependence of FIR for the (F23,F33)-H63 and H43-3H6 emissions, it has been found the sample exhibits a higher SR value but a lower SA value relative to the Yb3+-Er3+ codoped BLP.

AB - To establish optical links between an optical ground station (OGS) and a quantum experiment satellite, a method of acquisition for the Micius satellite is proposed in this paper and the acquisition technological specification of the OGS system is analyzed. An acquisition strategy for the OGS is designed to meet the requirements of the quantum experiments. A method is designed to point accurately at the quantum satellite and improve the absolute pointing precision. The results show that the correction accuracy is better than 5 MUrad, the acquisition time is less than 5 s, and the acquisition probability is 100% so far. PMID- 29469834 TI - Near-infrared absorbers based on the heterostructures of two-dimensional materials. AB - Although the conductance and dielectric function of graphene can be tuned by applying external voltage, the tunability is less than 3%. Hybridizing graphene with other two-dimensional transition metal dichalcogenides (TMDs) can improve the adjustability and tunability of the optical properties of graphene-based structures at near-infrared frequencies. In this paper, we theoretically compute the dielectric function of graphene-MoTe2-graphene and graphene-MoTe2-graphene heterostructures utilizing the quantum electrostatic heterostructure (QEH) model, which is an ab-initio method. Utilizing the QEH results, we propose a hyper crystal (HC) absorber at near-infrared frequencies. Hence, we use the transfer matrix method to investigate our proposed absorber analytically. Moreover, we simulate the graphene-TMD-graphene (G-TMD-G) absorbers by the numerical finite difference time domain method. The results of the numerical solution are consistent with those of the analytical method. Due to the dependency of the Fermi level of graphene on the direct bandgap of the TMDs, the dielectric function of the G-TMD-G heterostructure can be tuned and enhanced further by changing the number of TMD layers. Finally, we demonstrate that the full absorption of the heterostructures can be achieved at different frequencies for transverse magnetic polarization. Since the thicknesses of the layers in the HC are lower than the wavelength of the light, no diffracted bands are ubiquitous, and the absorption can be observed for a wide range of incidence angles and bandwidths at near-infrared frequencies. Because of utilizing graphene-based HCs, in addition to the feasibility of design compared to the complex metasurfaces, the absorption bandwidth is significant for a wide range of incidence angles. This kind of HC absorber can be used in the design of sensitive optical devices, such as tunable filters, detectors, and photovoltaic applications. PMID- 29469835 TI - Design of a high-efficiency train headlamp with low power consumption using dual half-parabolic aluminized reflectors. AB - We propose a train headlamp system using dual half-circular parabolic aluminized reflectors. Each half-circular reflector contains five high-efficiency and small package light-emitting diode (LED) chips, and the halves are 180 degrees rotationally symmetric. For traffic safety, the headlamp satisfies the Code of Federal Regulations. To predict the pattern of illumination, an analytical derivation is developed for the optical path of a ray that is perpendicular to and emitted from the center of an LED chip. This ray represents the main ray emitted from the LED chip and is located at the maximum illuminance of the spot projected by the LED source onto a screen. We then analyze the design systematically to determine the locations of the LED chips in the reflector that minimize electricity consumption while satisfying reliability constraints associated with traffic safety. Compared to a typical train headlamp system with an incandescent or halogen lamp needing several hundred watts, the proposed system only uses 20.18 W to achieve the luminous intensity requirements. PMID- 29469836 TI - Rapid super-resolution confocal microscopy through virtual structured detection based on serial scanning in array. AB - To improve the imaging speed of a confocal microscope with virtual structured detection, we have designed an optical system with rigid coordination control of the CCD, galvanometer scanner, and laser diode. In this system, the width of the coherent transfer function expands, which enhances the lateral resolution by a factor of 1.4. Also, the temporal image sequence is transformed to a spatial one so that multiple images can be acquired during a single exposure period of the CCD. This method increases the system imaging speed 25-fold at least, and an even higher speed can be achieved by further increasing the number of spots recorded during a single exposure period.

AB - This paper proposed a novel real-time compression load measurement system for a kayaking paddle based on optical fiber technology. The optical fiber sensor, fiber Bragg grating, is embedded in a 2 mm polydimethylsiloxane membrane, which serves as a pressure mat that can be easily attached/detached to/from the kayaking paddle. The proposed system is proposed for measuring and evaluating both handgrip loading and paddle blade load distribution during on-water kayaking, e.g., peak compression load distribution pattern and duration of the paddle blade in real time. Both indoor prototype experiment results and on-water experimental data on an expert paddler were presented to demonstrate the application potential of the proposed system.

AB - We have designed, fabricated, and tested an amplitude diffractive optical element for generation of two-dimensional (2D) Airy beams. The design is based on a detour-phase computer-generated hologram. Using laser ablation of metallic films, we obtained a 2 mm*2 mm diffractive optical element with a pixel of 5 MUm*5 MUm and demonstrated a fast, cheap, and reliable fabrication process. This device can modulate 2D Airy beams or it can be used as a UV lithography mask to fabricate a series of phase holograms for higher energy efficiency. Tests according to the premise and an analysis of the transverse profile and propagation are presented. PMID- 29469839 TI - High dynamic range 3D shape measurement based on the intensity response function of a camera. AB - Fringe projection profilometry has been widely used in many fields for its advantages such as high speed, high accuracy, and robustness to environmental illumination and surface texture. However, it is vulnerable to high dynamic range (HDR) objects. To this end, we propose a technique that can enhance the dynamic range of the fringe projection profilometry system. According to the surface reflectivities of the measured objects, several groups of fringe patterns with optimal light intensities are generated based on the intensity response function of a camera. The HDR fringe images are acquired by fusing these fringe patterns, and a three-step phase-shifting algorithm is used to obtain the unwrapped phase from the fused images. Experimental results demonstrate that the proposed technique can accurately measure objects with an HDR of surface reflectivity variation.

AB - In this study, the scattering of plane waves by a half-plane with different face impedances, which lie between isorefractive media, is analyzed. A new approach for the solution of this scenario is proposed. According to this proposal, the problem of isorefractive media and an impedance half-plane is modeled by a junction of resistive and impedance sheets. Thus the diffraction coefficient of the construction is obtained with the aid of the equivalent problem. The uniform expression of the diffracted waves is derived by the method of the uniform theory of diffraction. The scattered and diffracted waves are investigated numerically. PMID- 29469841 TI - Nonrotationally symmetric aberrations of off-axis two-mirror astronomical telescopes induced by axial misalignments. AB - In unobscured off-axis astronomical telescopes with an offset pupil, the effects of axial misalignments are very different from those in on-axis ones. Specifically, a series of nonrotationally symmetric aberrations with characteristic field dependence will be induced by axial misalignments. This paper takes off-axis two-mirror astronomical telescopes as an example to discuss the field characteristics of several important nonrotationally symmetric aberrations (including astigmatism, coma, and trefoil aberration) induced by axial misalignments in off-axis astronomical telescopes. The expressions of these aberrations are derived under some approximations. The accuracy of the proposed expressions is demonstrated. The specific field characteristics of these aberrations are presented and explicated. It is shown that the effects of axial misalignments bear strong similarities to the effects of the lateral misalignments in the symmetry plane of the off-axis system. On the other hand, the inherent relationships between astigmatism and coma induced by axial misalignments are further revealed, which are different from those induced by lateral misalignments. This fact presents the possibility of separating the effects of axial misalignments and lateral misalignments. Most of this work can be extended to other off-axis astronomical telescopes with more freedom. PMID- 29469842 TI - Aberration laser beams with autofocusing properties. AB - We investigate theoretically, numerically, and experimentally a novel type of laser beam-an aberration laser beam (ALB). To generate the ALB, a diffractive optical element with a phase transmission function having an arbitrary radial dependence of power q and a periodic angular dependence of sin(mphi) or cos(mphi) form can be used. Such a light distribution is more general than classic aberrations including Zernike polynomials. We demonstrate that such radial nonuniformity results in autofocusing properties of ALBs. The autofocusing feature of ALBs is analogous to that of circular Airy beams, but the ALBs' autofocusing feature has more flexibility. The presence of the periodic angular dependence in the phase results in a diffraction pattern with mth-order symmetry. Transformation of ALBs during propagation in free space is analogous to transformation of the three-Airy beams; however, the generated light distributions have an arbitrary integer order of symmetry. The presence of an additional focusing lens leads to formation of an optical field in its focal plane with symmetry that depends on the parity of m: for even m, the generated light distribution has 2mth-order symmetry, and, for odd m, it has mth-order symmetry. PMID- 29469843 TI - Investigation of the interpolation method to improve the distributed strain measurement accuracy in optical frequency domain reflectometry systems. AB - We use a spectrum interpolation technique to improve the distributed strain measurement accuracy in a Rayleigh-scatter-based optical frequency domain reflectometry sensing system. We demonstrate that strain accuracy is not limited by the "uncertainty principle" that exists in the time-frequency analysis. Different interpolation methods are investigated and used to improve the accuracy of peak position of the cross-correlation and, therefore, improve the accuracy of the strain. Interpolation implemented by padding zeros on one side of the windowed data in the spatial domain, before the inverse fast Fourier transform, is found to have the best accuracy. Using this method, the strain accuracy and resolution are both improved without decreasing the spatial resolution. The strain of 3 MUepsilon within the spatial resolution of 1 cm at the position of 21.4 m is distinguished, and the measurement uncertainty is 3.3 MUepsilon. PMID- 29469844 TI - Second-harmonic-generation-based technique for examining laser diode wavelength dynamics in the MUs to ms range. AB - Wavelength information is essential for any researcher in optics and photonics, and for this reason, a wide range of devices is available for measuring it. However, the techniques available today are limited either to a resolution of nanometers or a measurement rate of kHz. In this paper, we present a simple but highly versatile technique based on second-harmonic generation to measure fast wavelength dynamics of laser diodes. We demonstrate a resolution of 0.7 pm and a measurement rate in the MHz range. The measurement rate is limited only by the photodetector, and the wavelength resolution is limited mainly by the length of the nonlinear crystal and the noise of the detectors. The technique can, e.g., be used to investigate the mode-hop behavior of laser diodes during pulsed operation. To demonstrate this, we show the wavelength changes of a laser diode during a single pulse. PMID- 29469845 TI - Inverse design of optical elements based on arrays of dielectric spheres. AB - Arrays of wavelength scale scatterers are a promising platform for designing optical elements with a compact footprint. The large number of degrees of freedom in this system allows for unique and plentiful functionalities. However, the many variables also create a complex design problem. While intuitive forward design methods work for simple optical elements, they often fail to produce complicated elements, especially those involving multiple elements. We present an inverse design methodology for large arrays of wavelength scale spheres based on both adjoint optimization or sensitivity analysis and generalized multi-sphere Mie theory as a solution to the design problem. We validate our methodology by designing two sets of optical elements with scatterers on sub-wavelength and super-wavelength periodic grids. Both sets consist of a singlet and a doublet lens with one and two layers of spheres respectively designed for 1550 nm. The designed NA is ~0.33 (~0.5) for the sub-wavelength (super-wavelength) periodic structure. We find that with the sub-wavelength periodicity, the full width at half-maximum of the focal spot produced by the singlet and doublet is smaller than that produced by an ideal lens with the same geometric parameters. Finally, we simulate a realistic experimental scenario for the doublet, where the spheres are placed on a substrate with the same refractive index. We find the performance is similar, but with lower intensity at the focal spot and larger spot size. The method described here will simplify the design procedure for complicated multi functional optical elements and or scatterer array-based volume optics based on a specified figure of merit.

The DVII 3D display consists of a display panel, a polarized parallax barrier, a microlens array, and two pairs of polarized glasses. Two kinds of elemental images, which are captured from two different 3D scenes, are alternately arranged on the display panel. The polarized parallax barrier is attached to the display panel and composed of two kinds of units that are also alternately arranged. The polarization directions between adjacent units are perpendicular. The polarization directions of the two pairs of polarized glasses are the same as those of the two kinds of units of the polarized parallax barrier, respectively. The lights emitted from the two kinds of elemental images are modulated by the corresponding polarizer units and microlenses, respectively. Two different 3D images are reconstructed in the viewing zone and separated by using two pairs of polarized glasses. A prototype of the DVII 3D display is developed and two 3D images can be presented simultaneously, verifying the hypothesis.

AB - We report on the demonstration of Doppler-free spectroscopy of metastable Sr atoms using a hollow cathode lamp (HCL). We employed a custom Sr HCL, which is filled with a mixture of 0.5 Torr Ne and 0.5 Torr Xe as a buffer gas to suppress velocity changing collisions and increase the populations in all of the (5s5p)3PJ(J=0,1,2) metastable states. We performed frequency modulation spectroscopy for the (5s5p)3P0-(5s6s)3S1, (5s5p)3P1-(5s6s)3S1, (5s5p)3P2 (5s5d)3D2, and (5s5p)3P2-(5s5d)3D3 transitions with sufficient signal-to-noise ratios for laser frequency stabilization. We also observed the hyperfine transitions of (5s5p)3P2-(5s5d)3D3 of Sr87. This method would greatly facilitate laser cooling of Sr. PMID- 29469848 TI - Comparison of imaging fiber bundles for coherence-domain imaging. AB - Use of imaging fiber bundles for coherence-domain imaging has remained limited to date. In this work, we provide characterization of commercially available imaging bundles for coherence-domain imaging, by evaluating their modal structure for applicability to interferometric imaging. We further examine custom fabricated bundles developed in collaboration with a corporate partner for their ability to reduce interelement optical path length variability and cross talk between elements. The results presented here will serve as a useful guide for comparing fiber bundles for coherence imaging while also offering an improved understanding of the functionality and limitations of imaging bundles for advancing coherent imaging technologies. PMID- 29469849 TI - Highly thermal-stable heterodyne interferometer with minimized periodic nonlinearity. AB - Heterodyne interferometers suffer from thermal drift of optics (TDO), which may introduce error even up to several micrometers. In this paper, we propose a symmetric heterodyne interferometer with spatially separated beams, which realizes completely balanced optical paths between probe and reference beams and simultaneously avoids the optical mixing, and thereby is theoretically capable of eliminating TDO and the periodic nonlinearity (PNL). To validate the performance of the proposed interferometer, first a special experimental setup is constructed, with which the TDO test can be conducted in vacuum, and the result shows that a thermal coefficient of 1.2 nm/ degrees C is achieved. Next, the PNL of the proposed interferometer is measured by both the frequency domain method and the phase quadrature method, which demonstrates an undetectable PNL at a noise level of 13 pm. PMID- 29469850 TI - Watt-level tunable narrow bandwidth Tm:YAP laser using a pair of etalons. AB - We demonstrated in this paper a watt-level tunable, narrow band, end-pumped Tm:YAP laser. Spectral tunability of 35 nm ranging continuously between 1917-1951 nm with a spectral linewidth of 0.15 nm FWHM was achieved. The tuning and spectral band narrowing were obtained using a pair of YAG etalons. Watt-level output power was measured along the laser tunable range, obtaining a maximal output power of 3.88 W at 1934 nm. A slope efficiency of 44.8% is demonstrated for a maximal absorbed pump power of 12.1 W. The combination of the narrow bandwidth with tunability at those output power levels makes this laser a promising tool for biomedical, sensing, and material processing applications. PMID- 29469851 TI - Desensitization design method of unobscured three-mirror anastigmatic optical systems with an adjustment-optimization-evaluation process. AB - An off-axis three-mirror anastigmatic optical system with the offset apertures configuration as a typical unobscured optical system is frequently used in various optical instruments. The practical applications show that this type of system has a higher sensitivity in alignment. To reduce the alignment sensitivity of the unobscured optical systems, a desensitization design method with an adjustment-optimization-evaluation process is proposed. By ray path difference analysis based on the optical system mathematical models, the mirror off-axis magnitude value is determined as a significant factor influencing system alignment sensitivity. Accordingly, in the desensitization design process, the mirror off-axis magnitude value is set as an adjustment, and the image quality and system sensitivity are set as the criteria. By a design example, it proves that the desensitization design method is effective and practical, and the design result sensitivity analysis not only verifies that the off-axis magnitude is a significant factor that influences the system alignment sensitivity, but also finds that there is a positive correlation relation between system sensitivity and off-axis magnitude value. The desensitization method can design the unobscured optical systems with less alignment sensitivity and robust tolerance. PMID- 29469853 TI - Improvement of Scheimpflug systems with freeform surfaces. AB - It is well known that freeform surfaces are used to improve the resolution in systems without rotational symmetry. For Scheimpflug systems, the tilted object plane leads to variant magnification in the system imaging. Thus, the system suffers from non-rotationally symmetric aberrations, non-uniform resolution, and non-uniform intensity distribution. In this paper, the paraxial imaging condition of Scheimpflug systems is discussed. From the classical viewpoint, the aberration theory is used to understand, balance, and improve the system performance for variant object distance. For large object distance shift, it is necessary to apply freeform surfaces. With the initial system design method based on Gaussian brackets, the starting configuration of a Scheimpflug system with large object distance shift is obtained. Based on the extension of the Nodal aberration theory concerning the aberrations of freeform surfaces, the rules of selecting the freeform surface position in the system are introduced. By adding two freeform surfaces far away from the pupil, the aberrations are effectively corrected in the Scheimpflug system. The aberrations along the field are decomposed and represented using Zernike fringe polynomials to show the improvement of uniformity and resolution. This work provides insight into Scheimpflug system design with freeform surfaces. PMID- 29469852 TI - Air wedge with variable refractive index for precise laser beam steering in a small range. AB - This paper provides the results of work on a new method for metrological laser beam steering for the purpose of angular stabilization. Frequency stabilized metrological lasers are used for interference measurements of length and angle. Angular deviation of the beam may cause cosine errors when measuring displacements. This paper presents a method for metrological laser beam deflection with an air wedge of variable refractive index. The change in the index is achieved by changing the air pressure in the wedge volume. The implemented system produced a range of angular displacements of the 0.1 mrad (10 4 rad; 100 MUrad) beam with a resolution of 10-7 rad. PMID- 29469854 TI - All-fiber polarization-maintaining erbium-doped dispersion-managed fiber laser based on a nonlinear amplifying loop mirror. AB - In this paper, we build a mode-locked all-polarization-maintaining figure-of-8 erbium-doped fiber oscillator based on a nonlinear amplifying loop mirror. The fiber oscillator can generate 1.6 ps chirped pulses that can be de-chirped to 500 fs at 1550 nm with a pulse energy of 0.8 nJ and a repetition rate of 12 MHz. It can be further amplified up to 10 nJ and compressed down to 100 fs with a pre chirp managed nonlinear amplification setup. Such an oscillator and amplifier configuration has the advantages of self-starting and long-term operation, and it is highly suitable for subsequent frequency conversion, which is desirable for many applications in ultrafast microscopy and precision spectroscopy. PMID- 29469855 TI - High-energy diode side-pumped Er:LiYF4 laser. AB - This work presents a novel diode side-pumping scheme for Er:YLF with a characteristic laser emission at 2.81 MUm. Average output powers greater than 10 W and corresponding pulse energies exceeding 100 mJ with a high slope efficiency of 18.7% are achieved. The Er:YLF laser efficiently operates at room-temperature cooling water and maintains a good beam quality of M2<12 in the major axis and M2<6 in the minor axis of the beam profile. The laser cavity is studied by means of Findlay-Clay analysis, and the operation at characteristic pump parameters is investigated. In addition, a dynamic laser rate equation simulation is introduced for quantitative and qualitative comparison. This compact and scalable free running Er:YLF laser provides an effective building block for a subsequent Q switching concept. PMID- 29469856 TI - Spatially incoherent common-path off-axis color digital holography. AB - We describe a new method for recording spatially incoherent common-path off-axis color digital holograms. We present the theoretical and experimental evidence to demonstrate an incoherent common-path off-axis color digital holographic (ICOCH) system capable of capturing information from three-dimensional color objects under incoherent illumination, both in transmission and reflection modes. Fresnel incoherent correlation holography (FINCH), a common-path system, is a frequently used incoherent holography technique. Our proposed system is conceptually similar to an advanced form of FINCH; moreover, it has three advantages over this advanced form of FINCH. First, removal of the spatial light modulator makes our system simpler and more cost-effective. Second, removal of the polarizer or analyzer allows for greater light throughput. Third, the off-axis optical configuration enables separation of zero-order and twin images with only a single exposure per color rather than requiring three exposures per color for in-line holography FINCH. Therefore, we believe that this simple and cost-effective system with high light throughput can acquire incoherent holograms for different colors involving single exposure for each color, which makes the ICOCH system suitable for many applications. PMID- 29469857 TI - Design of a gradient-index lens with a compound parabolic concentrator shape as a visible light communication receiving antenna. AB - We propose a design for a gradient lens that can extend the field of view and receive higher optical power for indoor visible light communication systems. The proposed structure is an axially symmetric lens with a refractive index gradient distribution in the axial direction and a slight gradient in the radial direction, and with a spherical top surface and side surface in a compound parabolic concentrator (CPC) shape. The radius of the outlet of the CPC is 3 mm, and the inlet radius is 6.8 mm with a 9.04 mm radius of curvature. The height of the receiving system is 15.2 mm, resulting in the small volume of the structure. Simulation results show that the half field of view (FOV) of the lens can reach 36.2 degrees , while the gain is higher than that of a bare CPC. The designed receiving system has an average receiving gain ~1.72 times larger than a bare CPC based system, and is suitable for indoor visible light communication. PMID- 29469858 TI - High-performance color sequence particle streak velocimetry for 3D airflow measurement. AB - In this paper, a high-performance color sequence particle streak velocimetry (CSPSV) technique is proposed to measure the air velocity in a large three dimensional (3D) space. Based on the basic principle of CSPSV, a new color sequence illumination pattern is designed to mark seeding bubbles for better imaging performance. Synchronized with the illumination system, cameras record the targets' paths at the start, middle, and end points with different color information more clearly. Thus, a rectification-based stereo corresponding algorithm is presented to reconstruct the 3D trajectory of the bubbles. The accuracy of this system is verified and shows good consistency with a hot-wire anemometer (the principal research tool for turbulent-flow studies). The vortex test experiments also indicate its capability for complex airflow. Our high performance CSPSV can extend the 3D measurement zone from several cubic centimeters to several cubic meters with regular, off-the-shelf cameras. PMID- 29469859 TI - "Achromatic limits" of Pancharatnam phase lenses. AB - Lenses based on the Pancharatnam phase have the advantage of being thin and inexpensive. Unfortunately, their optical effect is strongly wavelength dependent, and their applications generally are limited by the requirement of a monochromatic source. However, low-power lenses based on the Pancharatnam phase can be considered for applications over the visible range. In this paper, we provide intuitive "limits" for the lens power, below which these devices can be considered for use with the eye and visible light imaging applications. PMID- 29469860 TI - Symmetric decomposition of experimental depolarizing Mueller matrices in the degenerate case. AB - We propose a detailed procedure to determine the two retardance matrix factors entering the symmetric decomposition of Mueller matrices when the depolarizer matrix is partially degenerate (i.e., two out of three of its depolarization coefficients are equal), which is a common occurrence. Thanks to a relatively simple algebraic method, we show that linear retardance, as well as its eigenaxes orientation can be determined unambiguously from each retardance matrix factor. The method, applied on both experimental Mueller matrices of an ad hoc sample, as well as on that of a biological tissue, shows its efficiency for decoupling the different polarimetric effects of retardance that occur during the propagation of light throughout a complex medium. PMID- 29469861 TI - Five-step phase-shifting white-light interferometry for the measurement of fiber optic extrinsic Fabry-Perot interferometers. AB - Five-step phase-shifting white-light interferometry is presented for interrogating the absolute cavity length of the fiber optic extrinsic Fabry-Perot interferometer (EFPI). It combines ideas of phase-shifting interferometry and white-light interferometry (WLI) to extend the measurement range of fiber optic WLI. Five sub-interferograms intercepted from the white-light optical spectrum are used to recover the optical path difference (OPD) of the EFPI. This method is demonstrated to interrogate a wider range of OPD. The experimental results show that the measurement resolution ranges from 0.5 MUm to 5 MUm with cavity length ranges from 16 MUm to 12,402 MUm, and it has a great advantage in measuring EFPIs with short cavity lengths. PMID- 29469862 TI - Tunable spectral and spatial filters for the mid-infrared based on hyperbolic metamaterials. AB - In this paper we present the possibility of shaping the reflectivity characteristics of tunable hyperbolic metamaterials (THMMs). Using the example of voltage-sensitive graphene-based structures, we demonstrate the existence of spectral and spatial functionalities of edge and narrowband filters, controlled dynamically over a 3-5 MUm spectral range, that are important for both civilian and military applications. We also demonstrate that the adoption of apodization techniques in the THMM design leads to a reduction in the sidelobe's parasitic effect in edge filters, as well as providing the means to reshape the overall reflectivity characteristics, which not only unveiled the tunable angle aperture functionality but also significantly increased the potential for tailoring optical properties of THMM nanostructures in general. PMID- 29469863 TI - Scattering characteristics of a cylindrical reflector covered with a general bi isotropic layer. AB - The scattering characteristics of an electric line source radiating in the presence of a bi-isotropic coated circular cylindrical reflector have been investigated using numerical calculations. The analytic expressions of the electric and magnetic fields in the bi-isotropic coating and the background medium have been found using the wave-field decomposition approach. It is studied that a bi-isotropic coating enhances the gain in the forward direction as compared to chiral, Tellegen, and dielectric coatings. It is found that for a thin coating layer, the scattering gains in the forward direction for chiral and bi-isotropic coatings are almost the same. It is investigated that a specific type of bi-isotropic coating can be used to significantly enhance the scattering gain in the forward direction. This type of enhanced forward direction scattering gain is preferred in point to point communications. On the other hand, it is found that a specific type of Tellegen coating significantly reduces the scattering gain in the backward direction. This phenomenon of reduced gain can be used to hide a cylindrical reflector in the backward direction. A comparative study of the scattering gains for realistic bi-isotropic and low-loss dielectric coatings has also been discussed. PMID- 29469864 TI - Computer-generated hologram marked by correlated photon imaging. AB - The computer-generated hologram (CGH) has been studied for many applications. In this paper, CGH is watermarked by correlated photon imaging. An input image is encoded into two cascaded phase-only masks by using the CGH principle. Subsequently, two different marks are independently encoded into one-dimensional (1D) intensity points by using correlated photon imaging (or ghost imaging), and the recorded 1D intensity points are embedded into the extracted phase masks for optical watermarking. During the decoding, the input is recovered by using two watermarked phase masks. To verify copyright of the recovered input image, information embedded in two phase-only masks is retrieved and used to decode the hidden marks. The decoded marks do not visually render clear information due to only a few measurements and, instead, are authenticated. It is illustrated that the quality of the recovered input image is high, and a different imaging approach can be applied in the CGH system for optical watermarking. The proposed approach provides a promising strategy for optical information security. PMID- 29469865 TI - Cost-effective plane-grating monochromator design for extreme-ultraviolet application. AB - The optical design of a plane-grating monochromator mainly intended for high resolution in the extreme ultraviolet and soft x-ray is presented. The configuration has three optical elements. It uses a uniform line-spaced plane grating illuminated in the converging light coming from a focusing concave mirror and an additional plane mirror that is needed to change the grating subtended angle to keep the system in focus on a fixed slit. The parameters of the focusing mirror are determined to introduce a coma that compensates for the coma given by the grating. A monochromator for the 12-50 eV region is designed for application to high-order laser harmonics. PMID- 29469866 TI - Design of an optical trap for storing femtosecond laser pulses. AB - An optical trap for storing femtosecond laser pulses to enhance the interaction effectiveness with optically thin targets is being proposed and investigated. Presently, we studied the trapping of 10-200 fs laser pulses of wavelength 800 nm, 1 MUJ energy per pulse, and 10 Hz repetition rate. To compensate the optical losses in the trap, a Ti: Sapphire crystal as an amplifying medium is being considered, which should be synchronously pumped by the second harmonic of the Nd: YAG laser. Due to the propagation of the short pulses through optical trap components, group velocity dispersion introduces a significant broadening in pulse duration. To compensate for this broadening, a chirped mirror with suitable parameters is being proposed. An increase of the average power of the laser pulse in the optical trap that includes an amplifying medium (Ti: Sapphire crystal) by a factor of 805 compared to a single passage of the laser pulse was derived. It should be possible to store the laser pulse in the optical trap for >4 MUs with constant power and with a repetition rate of up to 250 MHz. PMID- 29469867 TI - Freeform lens design to eliminate retroreflection for optical systems. AB - This paper presents an effective approach to alleviate the cat-eye effect by inserting a freeform single lens into the original optical system. By shifting the image of the given optical system transversely on the original image plane, the reflected beams originating from the sensor are subsequently blocked by the optical aperture, substantially eliminating retroreflections from the system. The influence of incident angle on retroreflected beams is analyzed in detail, and the optimal image translation distance for completely eliminating the cat-eye effect is also proposed via numerical simulations. According to the translation requirement, a freeform single lens comprised of two different freeform surfaces is designed for the given system as the only translation element. The design recipe is elaborated on the basis of phase pupil function. Furthermore, a design example is demonstrated to verify the feasibility of our proposal. After optimization with optical design software, the modulation transfer function (MTF) of the modified system after translation is close to the diffraction limit, and the cat-eye reflected beam could be eliminated thoroughly. PMID- 29469868 TI - Diverse mode of operation of an all-normal-dispersion mode-locked fiber laser employing two nonlinear loop mirrors. AB - In this paper, we propose an all-normal-dispersion ytterbium-fiber laser with a novel ring cavity architecture having two nonlinear amplifying loop mirrors (NALM) as saturable absorbers, capable of delivering distinctly different pulses with adjustable features. By optimizing the loop lengths of the individual NALMs, the cavity can be operated to deliver Q-switched mode-locked (Q-ML) pulse bunches with adjustable repetition rates, mode-locked pulses in dissipative soliton resonance (DSR) regime or noise-like pulse (NLP) regime with tunable pulse width. The DSR pulses exhibit characteristic narrowband spectrum, while the NLPs exhibit large broadband spectrum. The operation regime of the laser can be controlled by adjusting the amplifier pump powers and the polarization controllers. To the best of the authors' knowledge, this is the first demonstration of a single mode locked cavity where narrowband DSR pulses and broadband NLPs alongside Q-ML pulse bunches can be selectively generated by employing two NALMs. PMID- 29469869 TI - Nondestructive evaluation of demineralized enamel in a human incisor and molar using laser ultrasonics. AB - This study aims to evaluate early caries in human teeth with different geometry structures by using the dispersion curves of a surface acoustic wave (SAW) generated by a pulsed laser. Through the finite element method, SAWs propagating on teeth models with different enamel thickness and curvature radius were simulated, and the influence of the geometry difference on the dispersion curves of SAWs was discussed. Laser ultrasonic experiments were performed on an extracted human incisor and molar with different demineralization conditions. The received dispersive surface wave signals were processed via the spectral analysis method to obtain the dispersion curves, and the difference of the dispersion spectra between the incisor and the molar was analyzed and discussed. The result demonstrates that the laser generating the SAW has the ability to evaluate the elastic properties of early caries with different geometry nondestructively. PMID- 29469870 TI - Real-time identification of the singleness of a trapped bead in optical tweezers. AB - Beads trapped in optical tweezers are aligned along the optical propagation direction, which makes it difficult to determine the number of beads with bright field microscopy. This problem also dramatically influences the measurement of the optical trapping based single-molecule force spectroscopy. Here, we propose a video processing approach to count the number of trapped micro-objects in real time. The approach uses a normalized cross-correlation algorithm and image enhancement techniques to amplify a slight change of the image induced by the entry of an exotic object. As tested, this method introduces a ~10% change per bead to the image similarity, and up to four beads, one-by-one falling into the trap, are identified. Moreover, the feasibility of the above analysis in a moving trap is investigated. A movement of the trap leads to a fluctuation of less than 2% for the similarity signal and can be ignored in most cases. The experimental results prove that image similarity measurement is a sensitive way to monitor the interruption, which is very useful, especially during experiments. In addition, the approach is easy to apply to an existing optical tweezers system. PMID- 29469871 TI - Comb-referenced frequency-sweeping interferometry for precisely measuring large stepped structures. AB - A precise 3D surface measurement method for large stepped structures without height ambiguity is proposed based on optical-frequency-comb-referenced frequency sweeping interferometry and Fourier-transformed fractional phase retrieval. Unlike other interferometry that depends on the absolute phase value for several certain wavelengths, this method obtains results from the phase change during frequency sweeping and thus remains free from the confined non-ambiguity range. By reference to an optical frequency comb, the relative uncertainty from the tunable laser frequency was reduced by three orders of magnitude, and the sweeping frequency range can be precisely determined. Besides, the fractional phase can be rapidly retrieved in only one step using a Fourier transform method, with advantages of high accuracy and immunity to light intensity fluctuation and mechanical vibration noise. Samples of step heights from 1 MUm to 1 mm were measured, and the standard uncertainty was 45 nm. This permits applications such as quality assurance in microelectronics production and micro-electro-mechanical system (MEMS) manufacture. PMID- 29469872 TI - Compact optical multipass matrix system design based on slicer mirrors. AB - High path-to-volume ratio (PVR) and low-aberration-output beams are the two main criteria to assess the performance of multipass absorption cells. However, no substantial progress has been reported for large-numerical-aperture-coupled multipass cells, which is due to the accumulated aberrations caused by a large number of off-axis reflections. Based on Chernin's design, in this study, we modified Chernin's four-objective multipass matrix cell by using slicer mirrors to eliminate alignment difficulty and decrease the system volume. A generalized design routine based on user requirements is also proposed. Based on the automatic modeling tool package (Pyzdde) connected with Zemax and boundary conditions of the parameters selection proposed, a low-aberration-output beam and a high PVR are easily obtained compared with other multipass cells schemes. In one demo design, 108 passes (5*7 matrix spots) in a base length of 300 mm are presented. The PVR and peak-to-valley value wavefront errors are 67.5 m/L and 0.92 MUm, respectively. Finally, a tolerance analysis of this optical multipass system is also presented. This work may provide better broadband optical absorption cells in terms of response time and a better detection sensitivity in versatile applications. PMID- 29469873 TI - Calculation model of the scattering polarization coherency matrix for a detection system of oil spills at sea. AB - As a new analytical method to identify oil spills at sea, the main effect of a polarization measurement system is the scattering polarization information of different measured parts. To improve measurement accuracy, the scattering polarization characteristics of oil film and seawater were observed in this paper. A useful computational model, the scattering polarization coherency matrix (SPCM), was derived, which is a probabilistic mixture of the polarization coherency matrix. Combined with the Fresnel formula, the amplitude ratio and phase retardation were extracted to verify the scientific nature of the physical model. Experiments were performed, and the SPCM of the oil film and seawater were measured. In order to test the practicability of the model, we derived the degree of polarization from the SPCM and used it as the basis for identification of the actual oil spill at sea in the case of sunlight. Research indicated that the path of multiple scattering was in connection with the molecular structure and interactions of the medium. Under different measuring angles, the SPCM of the oil film and seawater have both differences and regularities; the experimental results indicate that it can be used for the rapid detection of an oil spill at sea, and the data are accurate and reliable. PMID- 29469874 TI - Temperature-dependent optical constants of highly transparent solids determined by the combined double optical pathlength transmission-ellipsometry method. AB - The optical constants of five highly transparent substrates (polycrystalline BaF2, CaF2, MgF2, ZnSe, and ZnS) were experimentally determined based on a combined technique using both the double optical pathlength transmission method and the ellipsometry method within temperature range 20 degrees C-350 degrees C in the ultraviolet-infrared region (0.2-20 MUm). The results show that the refractive index spectra of polycrystalline BaF2, CaF2, and MgF2 are similar, but differ from that of polycrystalline ZnSe and ZnS. The thermo-optic coefficient of these highly transparent substrates increases with increasing temperature. The absorption indices show a significant temperature-dependent behavior, which increases with increasing temperature from 20 degrees C to 350 degrees C over the transparent region. For the sake of application, the fitted formulas of the refractive index of the five highly transparent substrates as a function of wavelength and temperature are presented. PMID- 29469875 TI - Quantitative detection of oxygen in reduced graphene oxide by femtosecond laser induced breakdown spectroscopy. AB - This paper proposes a simple, direct, and fast method for the quantitative detection of oxygen in reduced graphene oxide (r-GO) by femtosecond laser-induced breakdown spectroscopy (fs-LIBS). First, GO was reduced by continuous-wave (CW) laser beams with different powers; subsequently, the oxygen content in the r-GO was detected through the intensity of oxygen obtained by fs-LIBS. The fit of the observed data and errors by LIBS was compared with the results of x-ray photoelectron spectroscopy (XPS), and the fs-LIBS results correlate well with the XPS results; it indicated that fs-LIBS can realize quantitative analysis of the GO-reduction degree. The method provides a convenient and time-efficient way for detecting the reduction degree of r-GO and can extend the applications of r-GO with different reduction degrees. PMID- 29469876 TI - Visible Infrared Imaging Radiometer Suite reflective solar bands on-orbit calibration using solar diffuser illuminated by scattered light through the nadir port. AB - A new variant to the standard on-orbit calibration of the reflective solar bands (RSBs) using a solar diffuser (SD) is formulated. Instead of direct solar exposure through the SD port in the front of the instrument as originally designed, the variant method uses light reflecting off Earth's surface coming through the nadir port as the light source to illuminate the built-in onboard SD. The methodology is applied to the Visible Infrared Imaging Radiometer Suite on board the Suomi National Polar-orbiting Partnership satellite, and is shown to be viable and useful. This approach effectively preserves the standard calibration pipeline other than using a different set of illumination data, corresponding to a different illumination source, for computing the radiance emanating from the SD. It has the added advantages of not dealing with operational needs for the standard calibration activities and completely bypassing the characterization of the transmission function of the attenuation screen in the front of the SD port. The RSB calibration coefficients are computed from the data of scattered light from the SD sector per each orbit, and a 16-day average is taken. The variant calibration coefficients are shown to well match the standard solar-based RSB calibration coefficients for Bands M5 to M8, but diverging results emerge for Bands M1 to M4, highlighting the known non-ideal behavior in the degradation of SD that contributes to the worsening error in RSB calibration. The result also shows a consistent 2% variation mission-long for all RSBs, showing the overall consistency of this first analysis of the new method but also the level of the uncertainty. The result and the implications of this study are discussed. PMID- 29469877 TI - Q-plates with a nonlinear azimuthal distribution of the principal axis: application to encoding binary data. AB - We encode q-plates where the angular orientation of the principal axis is varied spatially with a nonstandard distribution. In the usual q-plate design, the orientation of the optical axis depends linearly on the azimuthal angle. In this work, we examine cases where this azimuthal dependence is nonlinear. We consider two cases: first, where the principal axis distribution is like an inverse tangent function of the azimuth; and second, where it displays linear and flat segments. This last case is proposed as a new method for encoding binary data into the azimuthal lobes of the vector beam. We encode these patterns using a spatial light modulator system that allows new and exotic q-plate designs without the difficulty of fabricating individual plates. Experimental results are presented.

This form of an optical system can detect x-ray energy that is close to the optical axis, which solves the problems encountered by traditional Wolter-type systems. In this paper, we also propose a new design method to ensure that the entire telescope structure is compact and integrated. Finally, a proof-of-concept design with an acceptable image quality is proposed. PMID- 29469879 TI - Light-absorbing aerosol properties retrieved from the sunphotometer observation over the Yangtze River Delta, China. AB - In this study, aerosol optical depth (AOD) and extinction Angstrom exponent (EAE) are derived from ground-based sunphotometer observations between 2007 and 2014 at urban sites of Nanjing over the Yangtze River Delta. In addition, the present study aims to investigate aerosol light-absorbing properties such as single scattering albedo (SSA), absorption Angstrom exponent (AAE), and the aerosol absorbing optical depth (AAOD). The retrieval of aerosol properties is compared with AERONET inversion products. The results demonstrate that the retrieved AOD has a good agreement with the AERONET Level 1.5 data, with the root mean square error being 0.068, 0.065, and 0.026 for total, fine mode, and coarse mode at 440 nm, respectively. The SSA values indicate similar accuracies in the results, which are about 0.003, -0.009, -0.008, and 0.010 different from AERONET at 440, 670, 870, and 1020 nm, respectively. The occurrence frequency of background level AOD (AOD<0.10) at 440 nm in this region is limited (1%). Monthly mean AOD, SSA, the effective radius (Reff), and the volume concentration at 440 nm were 0.6-1.3, 0.85-0.92, 0.24-0.40 MUm, and 0.18-0.28 MUm3 MUm-2, respectively. The mean value of AAOD at 440 nm (AAOD440) was the highest in both summer (0.095+/-0.041) and autumn (0.094+/-0.042), but was the lowest in winter (0.079+/-0.036). It was also noted that SSA was found to be higher during summer (0.89+/-0.05). The spectral variation of SSA was observed to be strongly wavelength-dependent during all seasons. The seasonal mean AAE440-870 is the highest in winter (0.86+/-0.41) and lowest in spring (0.49+/-0.29). In winter, the cumulative frequency for AAE between 1.0 and 1.2 was about 87%. The peak in the AAE distribution was close to 1.0, indicating that the aerosol column was dominated by urban-industrial aerosols and absorption species other than black carbon. Analysis of the relationship between EAE and SSA showed that the aerosol populations could be classified as "mixed" aerosol, including a mixture of both anthropogenic particles and secondary organic aerosol with highly variable sphericity fraction.

AB - Polarization observation of sky radiation is the frontier approach to improve the remote sensing of atmospheric components, e.g., aerosol and clouds. The polarization calibration of the ground-based Sun-sky radiometer is the basis for obtaining accurate degree of linear polarization (DOLP) measurement. In this paper, a DOLP calibration method based on a laboratory polarized light source (POLBOX) is introduced in detail. Combined with the CE318-DP Sun-sky polarized radiometer, a calibration scheme for DOLP measurement is established for the spectral range of 440-1640 nm. Based on the calibration results of the Sun-sky radiometer observation network, the polarization calibration coefficient and the DOLP calibration residual are analyzed statistically. The results show that the DOLP residual of the calibration scheme is about 0.0012, and thus it can be estimated that the final DOLP calibration accuracy of this method is about 0.005. Finally, it is verified that the accuracy of the calibration results is in accordance with the expected results by comparing the simulated DOLP with the vector radiative transfer calculations. PMID- 29469881 TI - Accurate estimation of the illumination pattern's orientation and wavelength in sinusoidal structured illumination microscopy. AB - Structured illumination microscopy is able to improve the spatial resolution of wide-field fluorescence imaging by applying sinusoidal stripe pattern illumination to the sample. The corresponding computational image reconstruction requires precise knowledge of the pattern's parameters, which are its phase (phi) and wave vector (p). Here, a computationally inexpensive method for estimation of p from the raw data is proposed and illustrated with simulations. The method estimates p through a selective discrete Fourier transform at tunable subpixel precision. This results in an accurate p estimation for all the illumination patterns and subsequently improves the superresolution image recovery by a factor of 10 around sharp edges as compared to an integer pixel approach. The technique as presented here is of major interest to the large variety of custom-build systems that are used. The feasibility of the presented method is proven in comparison with published data. PMID- 29469882 TI - Microlens array expander with an improved light intensity distribution throughperiodic submicro-scale filling for near-eye displays. AB - A type of microlens array (MLA) expander with an improved light intensity distribution (LID) is designed and fabricated through submicro-scale filling, which could be applied to near-eye displays. Through the reflection of a 0.8-MUm wide metal filling, the light field is split and superimposed only through the microlens. The bright spot at the center of the LID is effectively eliminated. The results demonstrate that the expanded numerical aperture (NA) and focal length are about 0.38 and 19 MUm, respectively, and the error in the radius of curvature is within 5% between the experimental and designed values. An improved image quality with an 80% brightness uniformity for an area of 22*22 mm2 is realized through the MLA. Compared with the MLA based on thermal reflow, the largest NA is obtained with the smallest focal length and gap. The experimental LID is consistent with that obtained by a theoretical simulation. PMID- 29469883 TI - Focus detection by shearing interference of vortex beams for non-imaging systems. AB - In focus detection of non-imaging systems, the common image-based methods are not available. Also, interference techniques are seldom used because only the degree with hardly any direction of defocus can be derived from the fringe spacing. In this paper, we propose a vortex-beam-based shearing interference system to do focus detection for a focused laser direct-writing system, where a vortex beam is already involved. Both simulated and experimental results show that fork-like features are added in the interference patterns due to the existence of an optical vortex, which makes it possible to distinguish the degree and direction of defocus simultaneously. The theoretical fringe spacing and resolution of this method are derived. A resolution of 0.79 MUm can be achieved under the experimental combination of parameters, and it can be further improved with the help of the image processing algorithm and closed-loop controlling in the future. Finally, the influence of incomplete collimation and the wedge angle of the shear plate is discussed. This focus detection approach is extremely appropriate for those non-imaging systems containing one or more focused vortex beams. PMID- 29469884 TI - Principal frequency component analysis based on modulate chopper technique used in diffuse reflectance spectroscopy measurement. AB - Diffuse reflectance spectroscopy (DRS) is significantly affected from the interference of the ambient light and dark current of the instrument. Optical choppers, together with lock-in/synchronous amplification, can overcome these interferences. However, in spectral measurement, the sampling rate of the spectrometer is different from the Delta-pulse sampling, which is not high enough because of the integration time. In addition, the energy distribution is not perfectly concentrated as expected in modulate chopper technology. Therefore, in this study, based on the modulate chopper technique, we proposed a principal frequency component analysis (PFCA) method for DRS. This technique not only effectively eliminated the interference and dark current of the instrument but also improved the measurement precision using the energy of different frequencies. First, experiments were designed to successfully verify the function of optical choppers, eliminating the interference of the ambient light. Second, a set of 64 mixture solutions was designed and measured by DRS using the PFCA method to prove the feasibility of the proposed method. The solution was mixed with intralipid-20% suspension, India ink, and rhodamine B. These samples were analyzed by DRS under different conditions: no-chopper with overlapping and averaging, chopper demodulated by Fourier transform, and chopper demodulated by PFCA. The partial least square regression analysis was implemented to predict the concentration. Compared to the result of three methods, DRS equipped with chopper using the PFCA method showed the best results. The results of this study showed that the PFCA method not only satisfactorily eliminated the interference signals but also extracted useful information as much as possible, improving the analysis accuracy.

AB - In this paper, an experimental study of silicon-based avalanche photodiode (Si APD) with millisecond pulse laser irradiation was carried out, and the C-V curve of Si-APD was obtained by using a semiconductor analyzer. Based on the single side abrupt junction character of n+p, combined with the corresponding theoretical derivation, the doping concentration varying with the axial depth of damaged Si-APD was obtained by inverse computation. The lattice dislocation and junction reduction were the fundamental causes of the reduced doping concentration. The research results provide a new method for the study of the internal doping concentration for detectors with millisecond pulse laser damage.

AB - We theoretically and experimentally demonstrate a scheme to monitor the weight of a single orbital angular momentum (OAM) channel for coaxial multiplexed optical vortices with large mode spacing. A specially designed holographic grating is illuminated by the incident multiplexed vortices first. Then the weight of each single OAM channel is obtained after analyzing the captured diffraction patterns. This work will find applications in domains where multiplexed optical vortices are of interest, such as the OAM-based data-transmission system, and so on. PMID- 29469888 TI - Compact optical fiber temperature sensor with high sensitivity based on liquid filled silica capillary tube. AB - We propose a highly sensitive fiber temperature sensor based on a section of liquid-sealed silica capillary tube inserted in a single-multi-single-mode fiber structure. The liquid polymer is filled into the silica capillary tube through two micro-holes drilled by a femtosecond laser. Then the micro-holes are blocked by UV curable adhesive with ultra-small volume. Obvious Mach-Zehnder interference peaks were shown in its transmission spectrum. The proposed fiber temperature sensor can be reliably used for actual point detection owing to its high sensitivity (8.09 nm/ degrees C), good linearity (99.93%), compact size, good mechanical property, high fabrication efficiency, and good repeatability and stability. PMID- 29469890 TI - Temporal coherence study of four-wave mixing products with and without the laser cavity effect. AB - In this work, we have studied the temporal coherence property of a four-wave mixing (FWM)-assisted continuous-wave erbium-doped fiber ring laser source. To understand the temporal coherence characteristics of FWM, we have analyzed the visibility of their interference pattern with the help of a Mach-Zehnder-based fiber interferometer. The visibility of FWM sidebands is compared with respect to the input pumps, with and without the cavity effect. The stand-alone FWM without any cavity effect has a visibility comparable to its input coherent pumps, while the FWM in the presence of the cavity effect has a poorer visibility due to the intra-cavity noise arising from the amplified spontaneous emission, which is not entirely annulled in broadband lasers. The study also confirms that the visibility/temporal coherence property of FWM sidebands does not depend on the efficiency of their generation. PMID- 29469889 TI - Optimized star sensors laboratory calibration method using a regularization neural network. AB - High-precision ground calibration is essential to ensure the performance of star sensors. However, the complex distortion and multi-error coupling have brought great difficulties to traditional calibration methods, especially for large field of view (FOV) star sensors. Although increasing the complexity of models is an effective way to improve the calibration accuracy, it significantly increases the demand for calibration data. In order to achieve high-precision calibration of star sensors with large FOV, a novel laboratory calibration method based on a regularization neural network is proposed. A multi-layer structure neural network is designed to represent the mapping of the star vector and the corresponding star point coordinate directly. To ensure the generalization performance of the network, regularization strategies are incorporated into the net structure and the training algorithm. Simulation and experiment results demonstrate that the proposed method can achieve high precision with less calibration data and without any other priori information. Compared with traditional methods, the calibration error of the star sensor decreased by about 30%. The proposed method can satisfy the precision requirement for large FOV star sensors. PMID- 29469891 TI - Effect of angle-of-arrival fluctuation on heterodyne detection in slant atmospheric turbulence. AB - A mathematical model of the effect of random pointing errors on the mixing efficiency of heterodyne detection is established, and the effect of angle-of arrival fluctuation on the mixing efficiency of heterodyne detection is investigated. The results show that the average mixing efficiency is significantly affected by the angle-of-arrival fluctuation in the outer scale. The larger the obscuration ratio and receiving aperture of the optical system, the lower the average mixing efficiency is. The closer the value of D/r0 is to 0.79, the closer the bit error rate of heterodyne detection is to 1*10-9 under weak turbulence. PMID- 29469892 TI - Adjustable-focus ultracompact endoscopic lens design with ultrahigh optical performance. AB - An internally focusing design is developed for a compact endoscopic lens to have optical performance close to the diffraction limit. When changing the working distance from infinity to a predetermined short distance, the overall system length and the field of view remain constant. It is numerically demonstrated that the diffraction-limit-like performance is maintained over a wide range of working distances, showing a novel capability of adjustable focuses. The design concept is numerically proven to be feasible and can enable very high-resolution examination for doctors checking the positions of biological entities through the immediate capture of clear images at different working distances. The corresponding lens configuration, PNN, is shown to be useful in achieving the high-resolution performance once the number of lens elements is four, where P and N are used to denote positive and negative optical power, respectively, for the lens groups. A corresponding tolerance analysis is also presented. PMID- 29469895 TI - Highly amplified light transmission in a parity-time symmetric multilayered structure. AB - We propose a parity-time symmetric dielectric-nano-film-dielectric multilayered structure that could facilitate highly amplified transmission of optical power in the infrared spectrum. We have theoretically studied our model using the transfer matrix formalism. The reflection and the transmission coefficients of the S matrix are evaluated. The theoretical results are validated by FDTD numerical simulation. We have shown how the thickness of the layers and the gain/loss coefficient of the active layers could generate spectral singularities in the S matrix and how these singularities could be exploited to achieve amplified transmission of a single wavelength through the structure. PMID- 29469894 TI - Radiometric model for coaxial single- and multimode optical emission from double clad fiber. AB - Double-clad fibers (DCFs) are versatile waveguides supporting a single-mode core surrounded by a multimode inner cladding. DCFs are increasingly used for multimodal biomedical applications, such as imaging or therapy, for which the core is typically used for coherent illumination and the inner cladding, to support a concurrent modality. Proper optimization is, however, critical to ensure high optical performance and requires accurate modeling of coaxial single- and multimode output beams. In this paper, we present an approach based on geometrical optics and radiometry, which provides a simple and efficient modeling tool for designing and optimizing DCF-based systems. A radiometric definition of single- and multimode output beams in terms of irradiance and radiant intensity allows for the modeling of the energy distribution along the beams' propagation. We confirmed the validity of the model through comparison with experimental measurements and demonstrate the use of the model for optimizing a catheter for concurrent OCT and laser coagulation. PMID- 29469897 TI - Temperature-insensitive sum frequency generation of 355-nm ultraviolet laser radiation in LiB3O5 by compensating thermally induced phase mismatch. AB - A temperature-insensitive sum frequency generation method based on thermally induced phase mismatch compensation is proposed to enhance the thermal stability and scale up the output power of ultraviolet (UV) lasers. In the method, three LiB3O5 crystals are cascaded for sum frequency generation of a 355-nm UV laser, and the two crystals at the ends are employed for frequency conversion; the middle one, which is not required to be phase matched and has an opposite sign of first temperature derivative of phase mismatch, compensates the thermally induced phase mismatch generated in the first crystal. The temperature acceptance bandwidth of frequency conversion in the three cascaded crystals is about double that in a single long crystal with the same interaction length.

AB - In the present work, a spline-based integration technique for the reconstruction of a freeform wavefront from the slope data has been implemented. The slope data of a freeform surface contain noise due to their machining process and that introduces reconstruction error. We have proposed a weighted cubic spline based least square integration method (WCSLI) for the faithful reconstruction of a wavefront from noisy slope data. In the proposed method, the measured slope data are fitted into a piecewise polynomial. The fitted coefficients are determined by using a smoothing cubic spline fitting method. The smoothing parameter locally assigns relative weight to the fitted slope data. The fitted slope data are then integrated using the standard least squares technique to reconstruct the freeform wavefront. Simulation studies show the improved result using the proposed technique as compared to the existing cubic spline-based integration (CSLI) and the Southwell methods. The proposed reconstruction method has been experimentally implemented to a subaperture stitching-based measurement of a freeform wavefront using a scanning Shack-Hartmann sensor. The boundary artifacts are minimal in WCSLI which improves the subaperture stitching accuracy and demonstrates an improved Shack-Hartmann sensor for freeform metrology application. PMID- 29469898 TI - Distribution of splice loss in single mode optical fiber. AB - This work investigates a probabilistic model for splice loss in single mode optical fibers. We derive the probability density function for loss values as a function of lateral and angular misalignment. We then use observed data to estimate these model parameters; both Bayesian and maximum likelihood estimation procedures are described. These estimates can then be used to provide an indication of the relative importance of various loss mechanisms. Alternatively, if one is given values for maximum lateral and angular misalignment, our results allow for predictions of expected distribution of loss values. An overall goal of this paper is to demonstrate that, beyond the mean and variance of splice loss, there is significant information in the shape of the distribution of values. A second goal is to understand the trade-off between the number of splice loss measurements and the confidence in estimates of parameters in the splice loss model. PMID- 29469896 TI - Wavefront reconstruction of a non-coaxial diffraction model in a lens system. AB - To reconstruct a wavefront in a non-coaxial lens system, we propose a diffraction model using the Fresnel integral. Inclination angle is the newly included parameter in the mathematical formula describing beam propagation. It is determined through two ways in this paper, which are correlation operation and optical flow method. Furthermore, the multi-image phase retrieval is incorporated to reconstruct the complex optical field of sample from an overdetermined dataset. The combination is much closer to the actual situation and thus more practical. The proposed diffraction model is validated by numerical analysis and experiment. The work will further benefit the application of multi-image phase retrieval, such as in biomedical imaging and optical metrology.

AB - Background: Cardiovascular disease is the leading cause of mortality in India. Since it is largely driven by risk factors such as hypertension, diabetes and smoking, it is important to study the treatment cascade for these conditions and identify areas for improvement. Methods: This is a cross-sectional study from Project SEHAT (Study to Enhance Heart Associated Treatments), an ongoing cluster randomised controlled trial testing the hypothesis that a community health worker led intervention can improve the control of cardiovascular risk factors in a community in West Bengal, India. For the baseline data, 3556 adults, between the ages of 35 and 70, were screened for hypertension, diabetes and smoking. For hypertension and diabetes, an elevated reading was confirmed on a repeat visit. Results: 18.3% (n=650), 9.0% (n=317) and 14.1% (n=500) of adults were diagnosed with hypertension, diabetes and smoking, respectively. Overall, 35.0% (n=1242) adults had at least one of the three risk factors. 55.1% (n=358) of participants with hypertension and 40.4% (n=128) of participants with diabetes were unaware of their respective condition. 36.6% (n=238) of those with hypertension and 58.0% (n=184) of diabetics were on treatment. 8.2% (n=53) hypertensives were controlled (blood pressure <140/90 mm Hg) while 13.6% (n=43) diabetics were controlled (defined as fasting blood sugar <126 mg/dL). Less than 1% diabetics were on insulin, and average number of medications for a patient with hypertension was 1.2. Conclusions: In our population in semiurban India, one in three adults have a major cardiovascular risk factor, with low control rates. There is a large burden of undiagnosed cardiovascular risk factors and a large gap between treatment and control, which may be explained by lack of treatment intensification.

AB - Objectives: There have been limited data regarding the prediction of cardiac benefits after renal artery stenting for patients with atherosclerotic renal artery disease (ARAD). The aim of this multicentre retrospective study was to identify clinical or echocardiographic factors associated with improvements of cardiac symptoms after renal artery stenting. Methods: We enrolled 58 patients with de novo ARAD undergoing successful renal artery stenting for heart failure, angina or both between January 2000 and August 2015 at 13 hospitals. Results: Improvement of cardiac symptoms was observed in 86.2% of patients during a mean follow-up of 6.0+/-2.7 months. Responders demonstrated significantly lower New York Heart Association functional class, higher estimated glomerular filtration rate, lower serum creatinine and lower interventricular septal wall thickness (IVS), lower left ventricular mass index, lower left atrial dimension and lower E velocity than non-responders. Backward stepwise multivariate analysis identified IVS as an independent predictor of improvement of cardiac symptoms (OR 0.451, 95% CI 0.209 to 0.976; p=0.043). According to receiver operating characteristic curve analysis, an IVS cut-off of 11.9 mm provided the best predictive value, with sensitivity of 71.4%, specificity of 75.5% and accuracy of 73.5%. The positive predictive value was 74.5% and the negative predictive value was 72.5%. Conclusions: This multicentre retrospective study shows that the echocardiographic index of IVS is an independent predictor for improvement of cardiac symptoms after renal artery stenting.

AB - AIMS: To explore the unstimulated salivary flow rate and subjective feeling of oral dryness in young adult women with temporomandibular disorders (TMD) and their relation to the presence of chronic pain, depression, somatization, and limited mandibular mobility. METHODS: Unstimulated whole saliva flow rate and presence of oral dryness were determined in 45 women with TMD and 30 healthy controls. The Research Diagnostic Criteria for TMD (RDC/TMD) were used for assessment of TMD, chronic pain, depression, somatization, and mandibular mobility. Factors with P < .05 in the bivariate analysis were included in multivariate modeling. RESULTS: The TMD patients showed significantly diminished unstimulated salivary flow (P = .010) in comparison to controls, but there was no difference in subjective oral dryness. Within the TMD group, patients with mandibular hypomobility and free from somatization exhibited significantly lower salivary output (P = .037; P = .015, respectively). No relationship between salivary flow and depression or TMD pain was observed. Multivariate linear regression identified somatization as the single variable contributing to salivary flow (P = .044) in the TMD patients. CONCLUSION: The present study shows a relationship between TMD and lower salivary flow but no evidence of a relationship between TMD and subjective oral dryness in young adult women. Somatization was the single variable to emerge from the evaluation of potential factors contributing to salivary output in TMD patients. PMID- 29469907 TI - Trend in prevalence of coronary artery disease and risk factors over two decades in rural Punjab. AB - Objectives: The burden of coronary artery disease (CAD) has increased in the last three decades in low-income and middle-income countries including India. CAD is responsible for 20% deaths in India. The burden of CAD has increased due to a higher prevalence of risk factors related to the changing lifestyle. We studied the change in prevalence of CAD and risk factors over 20 years in a rural area. Methods: A rural population of adults over the age of 30 years from three villages of Punjab was surveyed for the prevalence of CAD and its risk factors in 1994 and 2014 using similar research methodology. CAD was diagnosed by Epstein and clinical criteria. Blood pressure, anthropometry, ECG and biochemical analysis were carried out. The findings of two surveys were compared with a look at the change in the prevalence of CAD and its risk factors over 20 years. Results: The overall age standardised prevalence of CAD increased from 2.79% in 1994 to 4.06% (p<0.05) in 2014. There was a significant increase in the prevalence of several risk factors including sedentary lifestyle (8.2% vs 41.3%, p<0.001), hypertension (14.5% vs 26.5%, p<0.001), diabetes (4.7% vs 9.7%, p<0.001), obesity (16.6% vs 35.4, p<0.001) and hypercholesterolaemia (7% vs 9.6%, p 0.011). In contrast, cigarette smoking (8.9% vs 3%, p<0.001) and use of desi ghee (51.4% vs 28.5%, p<0.001) decreased. Conclusions: In a rural population of Punjab, the prevalence of several CAD risk factors like sedentary lifestyle, hypertension, diabetes, obesity and hypercholesterolaemia increased over 20 years. These changes in risk factors were associated with a modest increase in prevalence of CAD.

AB - Synergetic effects between Pt and a cheap metal, downshift of the d-band center of Pt and the shape can boost the catalytic performance of Pt-based nanocrystals. Therefore, tailoring the shape and composition within the nanoscale is the key to designing a robust electrocatalyst in electrochemical energy conversion. Here, Cu rich PtCu octahedral alloys achieved by a composition-driven shape evolution route have been used as outstanding bifunctional electrocatalysts for both methanol oxidation (MOR) and oxygen reduction reaction (ORR) in an acid medium. When benchmarked against commercial Pt black or Pt/C, for MOR, the specific activity/mass activity on Pt34.5Cu65.5 octahedra is 4.74/7.53 times higher than that on commercial Pt black; for ORR, the specific activity/mass activity on Pt34.5Cu65.5 octahedra is 7.7/4.2 times higher than that on commercial Pt/C. After a current-time test for 3600 s, the remaining mass activity on Pt34.5Cu65.5 octahedra is 35.5 times higher than that on commercial Pt black for MOR. After undergoing 5000 cycles for ORR, the remaining mass activity on Pt34.5Cu65.5 octahedra is 4.2 times higher than that on commercial Pt/C.

AB - A new, simple protocol for the synthesis of acetals under basic conditions from non-enolizable aldehydes and alcohols has been reported. Such reactivity is facilitated by a sodium alkoxide along with a corresponding trifluoroacetate ester, utilizing formation of sodium trifluoroacetate as a driving force for acetal formation. The usefulness of this protocol is demonstrated by its orthogonality with various acid-sensitive protecting groups and by good compatibility with functional groups, delivering synthetically useful acetals complementarily to the synthesis under acidic conditions from aldehydes and alcohols.

AB - A study aimed at the synthesis and structure optimization of new, efficient, optically active beta-amino alcohol ligands with a structure suitable for immobilization on magnetite nanoparticles has been carried out. The optimized homogeneous amino alcohol catalysts 13a and 13b, the chirality of which arises from the Sharpless epoxidation of suitable allyl alcohols, were tested by employing the well-established enantioselective amino alcohol-promoted addition of diethylzinc to benzaldehyde, giving the corresponding benzyl alcohol with nearly quantitative yield and ee = 95%. Then, their broad applicability as chiral catalysts was evaluated by carrying out the same reaction on a family of aldehydes, including variously substituted aromatic ones as well as an aliphatic analogue. The results have confirmed the validity of the fine-tuning process performed on ligands 13a and 13b. In fact, both exhibited excellent catalytic activity as demonstrated by the chemical yields and ee obtained from all the tested aldehydes, almost independent of the position and type of substitution in the aromatic ring. PMID- 29469912 TI - Towards energy efficient separations with metal organic frameworks. AB - The huge energy requirement for industrial separations of chemical mixtures has necessitated the need for the development of energy efficient and alternative separation techniques in order to mitigate the negative environmental impacts associated with greenhouse gas emissions from fossil fuel combustions for energy generation. A promising approach involves the use of magnetic framework composites (MFCs) for gas capture and release via localised magnetic induction heating in a process known as magnetic induction swing adsorption (MISA). This feature article presents an overview of the mechanism of induction heating of magnetic nanoparticles, incorporation of the nanoparticles into metal organic frameworks to form MFCs and the potential of deploying MFCs for the mitigation of greenhouse gas emissions using the MISA process. We also present an overview of the potential energy savings as a result of the efficiency of magnetic induction heating and we give a perspective on the future directions in material and process development that could lead to widespread deployment of the MISA process for industrial separation operations.

AB - Carrageenan (CGN), a family of marine polysaccharides isolated from seaweeds, has been at the heart of considerable debate in recent years. To date, CGN is generally recognized as safe based on a history of safe use, various acute toxicology studies and some recent chronic toxicology tests. This review offers readers an overview of evidence on CGN characteristics and digestive fate that highlight various gaps in our understanding. Specifically, three unresolved gaps are identified. Firstly, little information can be found on the current levels of public exposure to CGN. Secondly, the link between CGN physicochemical properties, its impact on digestive proteolysis, the colon microbiome and inflammation are yet to be fully resolved. Thirdly, scant scientific evidence exists on the differential digestive fate of CGN in the gut of liable and predisposed populations, such as elderly people or IBD patients. Altogether, revisiting the scientific evidence indicates that more research is needed to elucidate the possibility that continued exposure to increasing levels of CGN in the human diet may compromise human health and well-being.

AB - Protein aggregation including the formation of dimers and multimers in solution, underlies an array of human diseases such as systemic amyloidosis which is a fatal disease caused by misfolding of native globular proteins damaging the structure and function of affected organs. Different kind of interactors can interfere with the formation of protein dimers and multimers in solution. A very special class of interactors are nanoparticles thanks to the extremely efficient extension of their interaction surface. In particular citrate-coated gold nanoparticles (cit-AuNPs) were recently investigated with amyloidogenic protein beta2-microglobulin (beta2m). Here we present the computational studies on two challenging models known for their enhanced amyloidogenic propensity, namely DeltaN6 and D76N beta2m naturally occurring variants, and disclose the role of cit-AuNPs on their fibrillogenesis. The proposed interaction mechanism lies in the interference of the cit-AuNPs with the protein dimers at the early stages of aggregation, that induces dimer disassembling. As a consequence, natural fibril formation can be inhibited. Relying on the comparison between atomistic simulations at multiple levels (enhanced sampling molecular dynamics and Brownian dynamics) and protein structural characterisation by NMR, we demonstrate that the cit-AuNPs interactors are able to inhibit protein dimer assembling. As a consequence, the natural fibril formation is also inhibited, as found in experiment.

AB - Winged bean seed (WBS) is an underutilized tropical crop. The current study evaluates its potential to reduce blood pressure (BP) in spontaneously hypertensive rats and finds that it reduces BP significantly, in a dose-dependent manner. Five peptides with the sequences, RGVFPCLK, TQLDLPTQ, EPALVP, MRSVVT and DMKP, have been characterized in terms of their stability against ACE via in vitro and in silico modelling. All peptides exhibited IC50 values between 0.019 and 6.885 mM and various inhibitory modes, including substrate, prodrug and true inhibitor modes. The toxicity status of non-Current Good Manufacturing Practice (non-CGMP) peptides is evaluated and the results show that such peptides are toxic, and thus are not suitable to be tested in animals, particularly in repeated-dose studies. In short, WBS hydrolysate demonstrated in vitro ACE inhibitory properties and in vivo blood pressure lowering efficacy in rat models, fostering its potential as a functional food ingredient. Non-CGMP grade peptides are toxic and unfit for testing in animal models.

AB - In order to establish the correlation between the magnetoelectric coupling and magnetic instability, we have studied the structural, magnetic, and ferroelectric properties of BaTiO3 modified BiCoO3i.e. xBaTiO3-(1 - x)BiCoO3 as a function of BaTiO3 concentration (x) and volume from a series of general-gradient-corrected (GGA), GGA plus onsite Coulomb repulsion (U), full potential, spin-density functional band-structure calculations within the framework of density functional theory along with synchrotron X-ray diffraction and magnetic measurement studies. G-type antiferromagnetic ordering was found to be energetically favorable among all the considered magnetic configurations for x < 0.45 and higher concentrations stabilize with nonmagnetic (NM) states. We observe metamagnetic spin state transitions associated with paraelectric to ferroelectric transitions as a function of volume and x using synchrotron diffraction and computational studies, indicating a strong magnetoelectric coupling. Specifically for x = 0.33 composition, a pressure induced high spin (HS) to low spin (LS) transition occurs when the volume is compressed below 2.5%. Our orbital-projected density of states show a HS state for Co3+ in the ferroelectric ground state for x < 0.45 and the corresponding paraelectric phase is stable in the NM state due to the stabilization of LS state as evident from our fixed-spin-moment calculations and magnetic measurements. The nature of chemical bonding has been studied using partial density of states, electron localization function, and Born effective charge analysis. High values of spontaneous ferroelectric polarizations are predicted for lower x values which inversely vary with x because of the reduction of tetragonality (c/a) with increase in x which indicates the presence of both spin-lattice and ferroelectricity-lattice coupling. Our partial polarization analysis shows that not only the lone pair at Bi sites but also the d0-ness of Ti4+ ions contribute to the net polarization. Moreover, we find that the HS-LS transition point and magnetoelectric coupling strength can be varied by x.

AB - Mixing gamma-cyclodextrin (gamma-CD), cucurbit[6]uril (CB[6]) and tetraammonium bearing axles together led to a spontaneous formation of gamma-CD-CB[6]-cowheeled [4]pseudorotaxanes. The well-defined unsymmetrical cavities thus formed enhance the binding affinity towards chiral amines by factors of several hundreds and show remarkably improved chiral discrimination. PMID- 29469923 TI - Revealing the nature of low-temperature photoluminescence peaks by laser treatment in van der Waals epitaxially grown WS2 monolayers. AB - Monolayers of transition metal dichalcogenides (TMD) are promising materials for optoelectronics devices. However, one of the challenges is to fabricate large scale growth of high quality TMD monolayers with the desired properties in order to expand their use in potential applications. Here, we demonstrate large-scale tungsten disulfide (WS2) monolayers grown by van der Waals Epitaxy (VdWE). We show that, in addition to the large structural uniformity and homogeneity of these samples, their optical properties are very sensitive to laser irradiation. We observe a time instability in the photoluminescence (PL) emission at low temperatures in the scale of seconds to minutes. Interestingly, this change of the PL spectra with time, which is due to laser induced carrier doping, is employed to successfully distinguish the emission of two negatively charged bright excitons. Furthermore, we also detect blinking sharp bound exciton emissions which are usually attractive for single photon sources. Our findings contribute to a deeper understanding of this complex carrier dynamics induced by laser irradiation which is very important for future optoelectronic devices based on large scale TMD monolayers.

PMID- 29469924 TI - T-cell-depleted haploidentical stem cell transplantation results improve with time in adults with acute leukemia: A study from the Acute Leukemia Working Party of the European Society of Blood and Marrow Transplantation (EBMT). AB - BACKGROUND: T-cell-depleted, haploidentical transplantations (haplos) are commonly offered to patients who have high-risk, acute leukemia in the absence of a human leukocyte antigen (HLA) full-matched donor. METHODS: To determine the effect of transplantation period, the authors divided 308 adults with de novo, acute leukemia who underwent T-cell-depleted haplo from 2005 to 2015 into 2 groups, according the year in which they underwent transplantation (2005-2011 [n = 191] and 2012-2015 [n = 117]). RESULTS: The median age was 41 years in patients who underwent transplantation before 2012 and 46 years in those who underwent transplantation after 2012 (P = .04). Most patients had acute myeloid leukemia (75% vs 69%; P = .26) and were in first complete remission (CR1) (55% vs 64%; P = .12) at the time of transplantation. The cumulative incidence of grade 2, 3, and 4 acute graft-versus-host disease (GvHD) and chronic GvHD were not different between the 2 groups (acute GvHD: 20% vs 22% cumulative incidence in patients who underwent haplo before and after 2012, respectively [P = .67]; chronic GvHD: 19% vs 11% cumulative incidence, respectively; P = .12]. The 2-year relapse incidence was 20%, the nonrelapse mortality (NRM) rate was 48%, and no difference was observed over time (21% vs 19% [P = .72] and 54% vs 38% [P = .11] for patients who underwent haplo before and after 2012, respectively). The main cause of NRM was infection. Haplo after 2012 (hazard ratio [HR], 0.57; P = .01), younger age (HR, 0.82; P = .02), and receipt of a reduced-intensity conditioning (RIC) regimen (HR, 0.53; P = .01) were independently associated with lower NRM. The 2 year overall survival rate was 36% and improved after 2012 (29% vs 47% before 2012; P = .02); and it was higher for patients who underwent transplantation in CR1 (41% vs 29%; P = .01). In multivariate analysis, haplo after 2012 (HR, 0.54; P = .003) and receipt of a RIC regimen (HR, 0.54; P = .005) were independently associated with better overall survival. Similarly, leukemia-free survival and GvHD-free/relapse-free survival (GRFS) improved over time: the leukemia-free survival rate was 31% (25% vs 43% in the groups who underwent transplantation before and after 2012, respectively; P = .05), and the GRFS rate was 24% (19% vs 34%, respectively; P = .09). In addition, leukemia-free survival and GRFS improved among patients who received a RIC regimen. CONCLUSIONS: The outcome of patients with acute leukemia who underwent T-cell-depleted haplo has improved over time. Cancer 2018;124:2142-50. (c) 2018 American Cancer Society. PMID- 29469926 TI - Folic Acid Supplementation throughout pregnancy: psychological developmental benefits for children. AB - AIM: To test the effect of folic acid supplements taken throughout pregnancy on children's psychosocial development. METHOD: A randomised controlled trial of folic acid supplementation in pregnancy, with parental rating using the Resiliency Attitudes and Skills Profile (RASP), the Strengths and Difficulties Questionnaire (SDQ) and the Trait Emotional Intelligence Questionnaire Child Short Form (TEIQue-CSF). Children aged 6-7 whose mothers received folic acid throughout pregnancy (n = 22) were compared to those whose mothers only received it during the first trimester (n = 17). RESULTS: Children whose mothers received the full-term supplement scored significantly higher on emotional intelligence and resilience. Hierarchical multiple regression analysis identified folate level at 36th gestational week as an important predictor of emotional intelligence (EI) and resilience. CONCLUSION: Although conclusions must be drawn with caution, this research presents a number of potential implications, the main one being a proposed policy recommendation for women to take folic acid for the duration of pregnancy rather than stopping at the end of the first trimester. The second is the potential for future research to explore the possible psychological and social development benefits and in line with this to try and identify the explanatory mechanism involved. PMID- 29469927 TI - Cost-effectiveness analysis of stent type in endoscopic treatment of gastric leak after laparoscopic sleeve gastrectomy. AB - BACKGROUND: Gastric leak is the most feared surgical postoperative complication after sleeve gastrectomy. An endoscopic procedure is usually required to treat the leak. No data are available on the cost-effectiveness of different stent types in this procedure. METHODS: Between April 2005 and July 2016, patients with a confirmed gastric leak undergoing endoscopic treatment using a covered stent (CS) or double-pigtail stent (DPS) were included. The primary objective of the study was to assess overall costs of the stent types after primary sleeve gastrectomy. Secondary objectives were the cost-effectiveness of each stent type expressed as an incremental cost-effectiveness ratio (ICER); the incremental net benefit; the probability of efficiency, defined as the probability of being cost effective at a threshold of ?30 000, and identification of the key drivers of ICER derived from a multivariable analysis. RESULTS: One hundred and twelve patients were enrolled. The overall mean costs of gastric leak were ?22 470; the mean(s.d.) cost was ?24 916(12 212) in the CS arm and ?20 024(3352) in the DPS arm (P = 0.018). DPS was more cost-effective than CS (ICER ?4743 per endoscopic procedure avoided), with an incremental net benefit of ?25 257 and a 27 per cent probability of efficiency. Key drivers of the ICER were the inpatient ward after diagnosis of gastric leak (surgery versus internal medicine), type of institution (private versus public) and duration of hospital stay per endoscopic procedure. CONCLUSION: DPS for the treatment of gastric leak is more cost-effective than CS and should be proposed as the standard regimen whenever possible. PMID- 29469928 TI - Obstructive Sleep Apnea and Neurocognitive Dysfunction in Edentulous Patients. AB - PURPOSE: To record the incidence of cognitive dysfunction in edentulous patients suffering from obstructive sleep apnea (OSA) and establish a plausible hypothesis to explain the correlation of cognitive dysfunction and OSA. MATERIALS AND METHODS: In this study, 315 edentulous patients (aged 60 to 65 years) visiting the outpatient department at Saraswati Dental College, Lucknow were recruited from January 2013 to October 2015. Prosthodontic Diagnostic Index (PDI) classification was used to assess the intraoral condition to relate it with the span of edentulousness. The BERLIN questionnaire and Epworth Sleepiness Scales were used to diagnose sleep-disordered breathing, following which the patients were put through all-night polysomnography. The apnea-hypopnea index (AHI) scores were derived. Mild and moderate OSA patients were classified into mild, moderate, and severe cognitive dysfunction based on SGRQ-C and SCD. Data were tabulated according to a new classification (Cognitive Dysfunction of Dental Sleep Medicine Patients [CDDSMP] Classification) designed specifically for this study. Data were analyzed using SPSS v15.0. Scores were tabulated as mean +/- SD and median [IQR] values. Change from baseline was analyzed using Wilcoxon signed rank test. RESULTS: Mean scores at different time intervals were 3.03 +/- 1.76 (3 months), 2.98 +/- 1.80 (6 months), and 2.81 +/- 1.84 (9 months). The median [IQR] values of scores at all time intervals except 9 months were 3 [1 to 5]. At 9 months, median [IQR] was 2 [1 to 5]. A significant change in scores was observed in the 3 month interval (p <= 0.001). CONCLUSIONS: The severity of OSA and neurocognitive dysfunction could be directly related to the PDI classification and the span of edentulousness of the patient and modified mandibular advancement device treatment significantly improved the patients' condition, which was reflective from 3 months post-intervention itself. PMID- 29469929 TI - Domperidone for increasing breast milk volume in mothers expressing breast milk for their preterm infants: a systematic review and meta-analysis. AB - BACKGROUND: Mothers of preterm infants often struggle to produce enough breast milk to meet the nutritional needs of their infant. Galactagogues such as domperidone are often prescribed to increase breast milk supply but evidence supporting their role in clinical practice is uncertain. OBJECTIVE: To evaluate the efficacy and safety of domperidone for increasing breast milk volume in mothers expressing breast milk for their preterm infants. SEARCH STRATEGY: MEDLINE, Embase and Web of Science were searched without language restrictions from first publication until January 2017. Bibliographies of articles and reviews were hand-searched for additional reports. SELECTION CRITERIA: Randomised controlled trials that compared domperidone with placebo in mothers of preterm infants (<37 weeks' gestation) experiencing insufficient milk supply. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed studies for inclusion, extracted data and evaluated study quality. Differences in breast milk volume and adverse events were combined using fixed effects meta-analysis. MAIN RESULTS: The pooled analysis of five trials consisting of 194 women demonstrated a moderate increase in daily breast milk volume of 88.3 ml/day (95% CI 56.8 119.8) with the use of domperidone compared with placebo. No difference was evident with respect to maternal adverse events (odds ratio 1.05, 95% CI 0.65 1.71), with no reported cases of prolonged QTc syndrome or sudden cardiac death. Sensitivity analyses showed no important differences in the estimates of effects. CONCLUSIONS: Domperidone is well tolerated and results in a moderate short-term increase in expressed breast milk volume among mothers of preterm infants previously identified as having insufficient breast milk supply. TWEETABLE ABSTRACT: Domperidone leads to short-term improvements in breast milk volume in mothers of preterm infants. PMID- 29469930 TI - Psychometric properties of the brief loss of control over eating scale (LOCES-B) in early adolescents. AB - OBJECTIVE: The purpose of this study was to evaluate the psychometric properties of the brief loss of control over eating scale (LOCES-B) in a community sample of adolescents. METHOD: Participants were 1,116 adolescents (11-15 years; 53% girls; 53% non-Hispanic White) recruited from middle schools in the Northeast United States. Participants were administered self-report surveys during school in the fall of 2016. RESULTS: Confirmatory factor analyses indicated that the LOCES-B total score was unidimensional, which was invariant across gender and weight status. The LOCES-B had excellent internal consistency (alpha = .92). The LOCES-B total score had large, positive relationships with the frequency of LOC eating episodes, objective bulimic episodes, and subjective bulimic episodes, and a small, positive relationship with objective overeating episode frequency. After adjusting for demographics, anthropometrics, and LOC eating frequency, adolescents reporting higher scores on the LOCES-B total score had greater body image dissatisfaction, more internalizing symptoms, and lower trait effortful control. DISCUSSION: Findings suggested that the LOCES-B is a reliable and valid measure of LOC eating in early adolescents. The availability of the LOCES-B has the potential to elucidate the developmental trajectories, predictors, and outcomes of LOC eating across the full severity spectrum in large cohort studies of youth. PMID- 29469931 TI - Development of Portable Flow-Through Electrochemical Sanitizing Unit to Generate Near Neutral Electrolyzed Water. AB - : We developed a portable flow-through, electrochemical sanitizing unit to produce near neutral pH electrolyzed water (producing NEW). Two methods of redirecting cathode yields back to the anode chamber and redirecting anode yields the cathode chamber were used. The NEW yields were evaluated, including: free available chlorine (FAC), oxidation-reduction potential (ORP), and pH. The performances of 2 electrodes (RuO2 -IrO2 /TiO2 and IrO2 -Ta2 O5 /TiO2 ) were investigated. The unit produced NEW at pH 6.46 to 7.17, an ORP of 805.5 to 895.8 mV, and FAC of 3.7 to 82.0 mg/L. The NEW produced by redirecting cathode yields had stronger bactericidal effects than the NEW produced by redirecting anode yields or NEW produced by mixing the commercial unit's anode and cathode product (P < 0.05). Electron spin resonance results showed hydroxyl free radicals and superoxide anion free radicals were present in the NEW produced by developed unit. The NEW generator is a promising sanitizing unit for consumers and the food industry to control foodborne pathogens. PRACTICAL APPLICATION: Current commercial NEW-producing units are quite large and are not convenient for family using. The developed portable flow-through, NEW-producing unit has great potential in a wide range of applications, such as organic farm, households, and small food industries. The examined sanitizing treatments showed effective control of Escherichia coli O157:H7 and Listeria monocytogenes. PMID- 29469932 TI - High control rates of proton- and carbon-ion-beam treatment with intensity modulated active raster scanning in 101 patients with skull base chondrosarcoma at the Heidelberg Ion Beam Therapy Center. AB - BACKGROUND: The current study compares the results of irradiation with protons and irradiation with carbon ions via a raster scan technique in patients with G1 and G2 skull base chondrosarcomas. METHODS: Between 2009 and 2014, a total of 101 patients (40 men and 61 women) with a median age of 44 years (range, 19-77 years) were irradiated with carbon ions (79 patients) or protons (22 patients) via a raster scan technique at the Heidelberg Ion Beam Therapy Center. The median total dose was 60 Gy (relative biological effectiveness [RBE]) at 3 Gy per fraction for carbon ions and 70 Gy (RBE) at 2 Gy per fraction for protons. The median boost planning target volume was 38 cm3 (range, 8-133 cm3 ). Overall survival (OS) and local control (LC) were evaluated with the Kaplan-Meier method. RESULTS: The median follow-up period was 40 months (range, 0.8-78.1 months). At the start of the irradiation, all patients had residual macroscopic tumors. Five patients (5%) developed a local recurrence during the follow-up. The 1-, 2-, and 4-year LC rates were 100%, 100%, and 100%, respectively, for protons and 98.6%, 97.2%, and 90.5%, respectively, for carbon ions. The OS rates during the same periods of time were 100%, 100%, and 100%, respectively, for protons and 100%, 98.5%, and 92.9%, respectively, for carbon ions. An age <= 44 years was associated with a trend for a better outcome. No toxicity worse than Common Toxicity Criteria grade 3 was observed after treatment. CONCLUSIONS: No significant difference between carbon ions and protons in the therapy of skull base chondrosarcoma could be detected in these initial retrospective results. Cancer 2018;124:2036-44. (c) 2018 American Cancer Society. PMID- 29469933 TI - Implicit attitudes toward eating stimuli differentiate eating disorder and non eating disorder groups and predict eating disorder behaviors. AB - OBJECTIVE: The current study tested whether people with and without eating disorders (EDs) varied in their implicit attitudes toward ED-relevant stimuli. Additionally, the study tested whether implicit evaluations of ED-relevant stimuli predicted ED symptoms and behaviors over a 4-week interval. METHOD: Participants were people without EDs (N = 85) and people seeking treatment for EDs (N = 92). All participants completed self-report questionnaires and a version of the affect misattribution procedure (AMP) at baseline. The AMP indexed implicit evaluations of average body stimuli, eating stimuli, and ED-symptom stimuli. Participants with EDs completed weekly follow-up measures of ED symptoms and behaviors for 4 weeks. RESULTS: Contrary to predictions, the anorexia nervosa (AN) group did not differ from the no ED group on implicit attitudes toward ED symptom stimuli, and the bulimia nervosa (BN) group had less positive implicit attitudes toward ED-symptom stimuli relative to the no ED group. In line with predictions, people with AN and BN had more negative implicit attitudes toward average body and eating stimuli relative to the no ED group. In addition, among the ED group more negative implicit attitudes toward eating stimuli predicted ED symptoms and behaviors 4 weeks later, over and above baseline ED symptoms and behaviors. DISCUSSION: Taken together, implicit evaluations of eating stimuli differentiated people with AN and BN from people without EDs and longitudinally predicted ED symptoms and behaviors. Interventions that increase implicit liking of eating-related stimuli may reduce ED behaviors. PMID- 29469934 TI - Microbial Quality and Shelf Life of Blueberry Puree Developed Using Cavitation Technology. AB - : Blueberry puree was developed using hydrodynamic cavitation technology. The product was made from entire blueberries without adding any food additives. In this study, microbial reduction following each processing stage (at the industry setting) and after product pasteurization at 86, 88, 90, 92, 94, and 96 degrees C was investigated. Microbial quality including total plate counts, yeast and molds, and heat-resistant molds counts was determined. Shelf life of pasteurized products stored for up to 24 weeks at room temperature were assessed for microbial quality, soluble solids ( degrees Brix), titratable acidity (citric acid %), pH, viscosity (cP) and flow rate (cm/30 s). Our results indicated that heat-resistant molds, initially present in frozen blueberries with counts at 2.03 log CFU/200g, were totally inactivated at 94 to 96 degrees C with 1 to 2 min holding time. Shelf life study showed that no product spoilage was caused by bacteria, yeasts and heat-resistant molds along with non-significant changes of textural characteristics. This study provided useful information for the food industry to develop variety of fruit puree products with no wastes of fruit materials. PRACTICAL APPLICATION: This study provides useful information for the food industry to develop safe liquid food products using cavitation technology without wasting any raw materials. PMID- 29469935 TI - Are children with chronic illnesses requiring dietary therapy at risk for disordered eating or eating disorders? A systematic review. AB - OBJECTIVE: Pediatric chronic illnesses (CI) can affect a child's mental health. Chronic illnesses with treatment regimens that specify a therapeutic diet may place the child at increased risk for disordered eating and specific eating disorders (ED). The aim of this review is to examine the relation between diet treated CI and disordered eating and to determine the order of onset to infer directionality. Diet-treated CI is hypothesized to precede and to be associated with disordered eating. METHOD: A comprehensive search of empirical articles that examine the relation between diet-treated CI (diabetes, cystic fibrosis, celiac disease, gastrointestinal disorders, and inflammatory bowel diseases) and disordered eating was conducted in Medline and PsycINFO using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A table of the sample's characteristics, ED measures, major pertinent findings, and the onset of CI in relation to ED were provided. RESULTS: Diet-treated CI was associated with disordered eating and ED. Diet-treated CI had onset prior to disordered eating in most studies, except for inflammatory bowel diseases. Disordered eating and unhealthy weight management practices put children at risk for poor medical outcomes. DISCUSSION: Interventions for diet-treated CI require a focus on diet and weight, but may increase the risk for disordered eating. Future research is needed to elucidate the mechanisms that transform standard treatment practices into pathological eating, including characteristics and behaviors of the child, parents/care providers, family, and treatment providers. PMID- 29469936 TI - 2D-3D registration for cranial radiation therapy using a 3D kV CBCT and a single limited field-of-view 2D kV radiograph. AB - PURPOSE: We present and evaluate a fully automated 2D-3D intensity-based registration framework using a single limited field-of-view (FOV) 2D kV radiograph and a 3D kV CBCT for 3D estimation of patient setup errors during brain radiotherapy. METHODS: We evaluated two similarity measures, the Pearson correlation coefficient on image intensity values (ICC) and maximum likelihood measure with Gaussian noise (MLG), derived from the statistics of transmission images. Pose determination experiments were conducted on 2D kV radiographs in the anterior-posterior (AP) and left lateral (LL) views and 3D kV CBCTs of an anthropomorphic head phantom. In order to minimize radiation exposure and exclude nonrigid structures from the registration, limited FOV 2D kV radiographs were employed. A spatial frequency band useful for the 2D-3D registration was identified from the bone-to-no-bone spectral ratio (BNBSR) of digitally reconstructed radiographs (DRRs) computed from the 3D kV planning CT of the phantom. The images being registered were filtered accordingly prior to computation of the similarity measures. We evaluated the registration accuracy achievable with a single 2D kV radiograph and with the registration results from the AP and LL views combined. We also compared the performance of the 2D-3D registration solutions proposed to that of a commercial 3D-3D registration algorithm, which used the entire skull for the registration. The ground truth was determined from markers affixed to the phantom and visible in the CBCT images. RESULTS: The accuracy of the 2D-3D registration solutions, as quantified by the root mean squared value of the target registration error (TRE) calculated over a radius of 3 cm for all poses tested, was ICCAP : 0.56 mm, MLGAP : 0.74 mm, ICCLL : 0.57 mm, MLGLL : 0.54 mm, ICC (AP and LL combined): 0.19 mm, and MLG (AP and LL combined): 0.21 mm. The accuracy of the 3D-3D registration algorithm was 0.27 mm. There was no significant difference in mean TRE for the 2D-3D registration algorithms using a single 2D kV radiograph with similarity measure and image view point. There was no significant difference in mean TRE between ICCLL , MLGLL , ICC (AP and LL combined), MLG (AP and LL combined), and the 3D-3D registration algorithm despite the smaller FOV used for the 2D-3D registration. While submillimeter registration accuracy was obtained with both ICC and MLG using a single 2D kV radiograph, combining the results from the two projection views resulted in a significantly smaller (P<=0.05) mean TRE. CONCLUSIONS: Our results indicate that it is possible to achieve submillimeter registration accuracy with both ICC and MLG using either single or dual limited FOV 2D kV radiographs of the head in the AP and LL views. The registration accuracy suggests that the 2D-3D registration solutions presented are suitable for the estimation of patient setup errors not only during conventional brain radiation therapy, but also during stereotactic procedures and proton radiation therapy where tighter setup margins are required. PMID- 29469937 TI - Radiomic features on MRI enable risk categorization of prostate cancer patients on active surveillance: Preliminary findings. AB - BACKGROUND: Radiomic analysis is defined as computationally extracting features from radiographic images for quantitatively characterizing disease patterns. There has been recent interest in examining the use of MRI for identifying prostate cancer (PCa) aggressiveness in patients on active surveillance (AS). PURPOSE: To evaluate the performance of MRI-based radiomic features in identifying the presence or absence of clinically significant PCa in AS patients. STUDY TYPE: Retrospective. SUBJECTS MODEL: MRI/TRUS (transperineal grid ultrasound) fusion-guided biopsy was performed for 56 PCa patients on AS who had undergone prebiopsy. FIELD STRENGTH/SEQUENCE: 3T, T2 -weighted (T2 w) and diffusion-weighted (DW) MRI. ASSESSMENT: A pathologist histopathologically defined the presence of clinically significant disease. A radiologist manually delineated lesions on T2 w-MRs. Then three radiologists assessed MRIs using PIRADS v2.0 guidelines. Tumors were categorized into four groups: MRI-negative biopsy-negative (Group 1, N = 15), MRI-positive-biopsy-positive (Group 2, N = 16), MRI-negative-biopsy-positive (Group 3, N = 10), and MRI-positive-biopsy negative (Group 4, N = 15). In all, 308 radiomic features (First-order statistics, Gabor, Laws Energy, and Haralick) were extracted from within the annotated lesions on T2 w images and apparent diffusion coefficient (ADC) maps. The top 10 features associated with clinically significant tumors were identified using minimum-redundancy-maximum-relevance and used to construct three machine learning models that were independently evaluated for their ability to identify the presence and absence of clinically significant disease. STATISTICAL TESTS: Wilcoxon rank-sum tests with P < 0.05 considered statistically significant. RESULTS: Seven T2 w-based (First-order Statistics, Haralick, Laws, and Gabor) and three ADC-based radiomic features (Laws, Gradient and Sobel) exhibited statistically significant differences (P < 0.001) between malignant and normal regions in the training groups. The three constructed models yielded overall accuracy improvement of 33, 60, 80% and 30, 40, 60% for patients in testing groups, when compared to PIRADS v2.0 alone. DATA CONCLUSION: Radiomic features could help in identifying the presence and absence of clinically significant disease in AS patients when PIRADS v2.0 assessment on MRI contradicted pathology findings of MRI-TRUS prostate biopsies.

PMID- 29469938 TI - Strength and cardiometabolic risk in young adults: The mediator role of aerobic fitness and waist circumference. AB - The aim of this study was to analyze the mediation role of cardiorespiratory fitness and waist circumference in the association between muscular strength and cardiometabolic risk. A cross-sectional study involved first-year college students (n = 370) from a Spanish public university was performed. We measured weight, height, waist circumference, blood pressure, biochemical variables, maximum handgrip strength assessment, and cardiorespiratory fitness. We calculated handgrip dynamometry/weight and a previously validated cardiometabolic risk index. Analysis of covariance models was conducted to test differences in cardiometabolic risk values across muscular strength, cardiorespiratory fitness, and waist circumference categories, controlling for confounders. Hayes' PROCESS macro was used for the multiple mediation analysis. The relationship between muscular strength and cardiometabolic risk did not remain significant (c' = 1.76 [1.4]; P > .05) in a multiple serial bootstrapped mediation model including cardiorespiratory fitness and waist circumference as mediators when controlling for age and sex. According to the indirect effect, the significant paths in the model mediating this relationship between muscular strength and cardiometabolic risk index were as follows: muscular strength -> waist circumference -> cardiometabolic risk index (-4.899; 95% CI: -6.690; -3.450) and muscular strength -> cardiorespiratory fitness -> waist circumference -> cardiometabolic risk index (-0.720; 95% CI: -1.316; -0.360). Both cardiorespiratory fitness and waist circumference mediate the association between muscular strength and cardiometabolic risk in young adults. Thus, our results place cardiorespiratory fitness and waist circumference as the main targets of physical activity programmes aimed at preventing cardiometabolic diseases. PMID- 29469939 TI - Proximate mechanisms of the differences in reproductive success of males bearing different alleles of Pgdh - a gene involved in a sexual conflict in bulb mite. AB - Enzyme polymorphism in phosphogluconate dehydrogenase (Pgdh) is a striking example of single gene polymorphism involved in sexual conflict in bulb mite Rhizoglyphus robini. Males homozygous for the S Pgdh allele were shown to achieve higher reproductive success than FF homozygous males, while negatively influencing fecundity of their female partners. Here, we investigate proximate mechanisms responsible for the increased reproductive success of SS males and find that the S allele is associated with shorter time until copulation, higher copulation frequency and increased sperm production. We also show that Pgdh alleles are probably codominant, with SS males gaining the highest reproductive success, FF males - the lowest - and FS-heterozygous males taking an intermediate position in all fitness parameters differentiating males of different genotypes. Additionally, we confirm the negative effect that S-bearing males impose on the fecundity of females they mate with, showing a clear pattern of interlocus sexual conflict. We discuss that this effect is probably associated with increased copulation frequency. Whereas, contrary to what we have predicted, the S allele does not cause increased general male mobility, we speculate that the S allele bearing males are more efficient in forcing copulation and/or detecting females. PMID- 29469940 TI - Different qualifiers of AUS/FLUS thyroid FNA have distinct BRAF, RAS, RET/PTC, and PAX8/PPARg alterations. AB - BACKGROUND: The Bethesda System for Reporting Thyroid Cytopathology category of atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS) includes fine-needle aspiration (FNA) specimens that cannot straightforwardly be classified as benign or malignant. To determine whether morphological subcategorization based on atypia qualifiers and molecular testing could improve malignancy risk stratification of AUS/FLUS patients, this study assessed the correlation between these qualifiers and the molecular alterations commonly harbored by thyroid neoplasms. METHODS: A total of 162 AUS/FLUS cases were subcategorized by atypia qualifiers (Hurthle cell changes, architectural atypia, and cytologic atypia [CyA]) and were tested for BRAF, N-H KRAS, RET/PTC, and paired box 8 (PAX8)/peroxisome proliferator activated receptor gamma (PPARg) mutations. RESULTS: CyA was observed more frequently in mutation positive AUS/FLUS (14 of 37 [37.84%]) than mutation-negative AUS/FLUS (20 of 125 [16.00%]; P < .0084), and it specifically harbored the BRAFV600E point mutation. Malignancy was confirmed in the available follow-up. Conversely, although RAS was the most frequent mutation identified in AUS/FLUS FNA specimens (26 of 37 cases [70.27%]; P < .0001), it was distributed across various AUS/FLUS subcategories and was not significantly associated with a specific atypia qualifier or malignant outcome according to the available follow-up. Rearrangements of both RET/PTC (n = 1) and PAX8/PPARg (n = 3) were rarely retrieved in the FNA samples. CONCLUSIONS: BRAF and RAS mutations are associated with different AUS/FLUS qualifiers and hence have different risks of malignancy. Consequently, a hybrid molecular and morphological subcategorization system could improve the malignancy risk stratification of thyroid FNA samples diagnosed as AUS/FLUS.

AB - BACKGROUND: Apparent diffusion coefficient (ADC) histogram analyses have been used to differentiate tumor grades and predict therapeutic responses in various anatomic sites with moderate success. PURPOSE: To determine the ability of diffusion-weighted imaging (DWI) with a whole-tumor ADC histogram analysis to differentiate benign peripheral neurogenic tumors (BPNTs) from soft tissue sarcomas (STSs). STUDY TYPE: Retrospective study, single institution. SUBJECTS: In all, 25 BPNTs and 31 STSs. FIELD STRENGTH/SEQUENCE: Two-b value DWI (b-values = 0, 1000s/mm2 ) was at 3.0T. ASSESSMENT: The histogram parameters of whole-tumor for ADC were calculated by two radiologists and compared between BPNTs and STSs. STATISTICAL TESTS: Nonparametric tests were performed for comparisons between BPNTs and STSs. P < 0.05 was considered statistically significant. The ability of each parameter to differentiate STSs from BPNTs was evaluated using area under the curve (AUC) values derived from a receiver operating characteristic curve analysis. RESULTS: The mean ADC and all percentile parameters were significantly lower in STSs than in BPNTs (P < 0.001-0.009), with AUCs of 0.703-0.773. However, the coefficient of variation (P = 0.020 and AUC = 0.682) and skewness (P = 0.012 and AUC = 0.697) were significantly higher in STSs than in BPNTs. Kurtosis (P = 0.295) and entropy (P = 0.604) did not differ significantly between BPNTs and STSs. DATA CONCLUSION: Whole-tumor ADC histogram parameters except kurtosis and entropy differed significantly between BPNTs and STSs. LEVEL OF EVIDENCE: 3 Technical Efficacy: Stage 2 J. Magn. Reson.

AB - BACKGROUND: Clinical signs of urinary tract disease in dogs often lead to prescription of antibiotics. Appropriate diagnostic work-up could optimize treatment and reduce the risk of inappropriate use of antibiotics. HYPOTHESIS/OBJECTIVES: To describe and evaluate the impact of diagnostic work-up on decision to treat (DTT) and choice of antibiotic treatment (COT) for dogs presenting with clinical signs of urinary tract disease. ANIMALS: One hundred and fifty-one dogs presenting to 52 Danish veterinary practices. METHODS: Prospective, observational study. Clinical signs, diagnostic work-up, and prescriptions were recorded. Urine samples were submitted to a reference laboratory for quantitative bacterial culture (QBC) and susceptibility testing. The laboratory results were used as reference for assessing the appropriateness of DTT and COT. RESULTS: In the majority of dogs, veterinarians performed dipstick (99%), microscopic examination of urine (80%) and bacterial culture (56%). Fifty-one percent of dogs had urinary tract infection (UTI) based on reference QBC. Appropriate DTT was made for 62% of the dogs, while 36% were over prescribed and 2% under-prescribed. Inappropriate use of second-line agents was found in 57% of the UTI cases. Performing microscopy-but not culture significantly impacted DTT (P = 0.039) while no difference was seen in COT (P = 0.67). The accuracy of in-house microscopy and culture were 64.5 and 77%, respectively. CONCLUSIONS AND CLINICAL IMPORTANCE: Over-prescription of antibiotics was common among dogs with suspected UTI, regardless of the diagnostic work-up performed. Test inaccuracy under practice conditions and incoherence between diagnostic test results and decision-making both explained inappropriate and unnecessary use of antibiotics. PMID- 29469944 TI - Multicentre randomized clinical trial of the effect of chewing gum after abdominal surgery. AB - BACKGROUND: Postoperative ileus is a common complication of abdominal surgery, leading to patient discomfort, morbidity and prolonged postoperative length of hospital stay (LOS). Previous studies suggested that chewing gum stimulates bowel function after abdominal surgery, but were underpowered to evaluate its effect on LOS and did not include enhanced recovery after surgery (ERAS)-based perioperative care. This study evaluated whether chewing gum after elective abdominal surgery reduces LOS and time to bowel recovery in the setting of ERAS based perioperative care. METHODS: A multicentre RCT was performed of patients over 18 years of age undergoing abdominal surgery in 12 hospitals. Standard postoperative care (control group) was compared with chewing gum three times a day for 30 min in addition to standard postoperative care. Randomization was computer-generated; allocation was concealed. The primary outcome was postoperative LOS. Secondary outcomes were time to bowel recovery and 30-day complications. RESULTS: Between 2011 to 2015, 1000 patients were assigned to chewing gum and 1000 to the control arm. Median LOS did not differ: 7 days in both arms (P = 0.364). Neither was any difference found in time to flatus (24 h in control group versus 23 h with chewing gum; P = 0.873) or time to defaecation (60 versus 52 h respectively; P = 0.562). The rate of 30-day complications was not significantly different either. CONCLUSION: The addition of chewing gum to an ERAS postoperative care pathway after elective abdominal surgery does not reduce the LOS, time to bowel recovery or the rate of postoperative complications.

PMID- 29469945 TI - Extravillous trophoblast invasion in placenta accreta is associated with differential local expression of angiogenic and growth factors: a cross-sectional study. AB - OBJECTIVE: Placenta accreta is clinically associated with maternal uterine scar. Our objective was to investigate the biochemical contribution of maternal scarring to hyperinvasive trophoblast. We hypothesised that trophoblast over invasion in placenta accreta is associated with aberrant invasion-site signalling of growth and angiogenic factors known to be involved in wound healing and promotion of cell invasion through the epithelial to mesenchymal cellular programme. DESIGN: Cross-sectional series. SETTING: Yale-New Haven Hospital. POPULATION: Women with histologically confirmed normal and abnormal placentation. METHODS: Placental invasion site tissue sections were immunostained for endoglin and other angiogenic regulators, and transforming growth factor beta (TGFbeta) proteins. Maternal serum endoglin, and the vascular endothelial growth factor (VEGF) mediators hypoxia-inducible factor-1alpha (HIF1alpha) and endostatin, were assessed using immunoassay. MAIN OUTCOME MEASURES: Differences in median H-score by immunostaining and in mean serum level by immunoassay. RESULTS: By immunostaining, placenta accreta samples demonstrated intervillous endoglin shedding and increased trophoblast expression of its cleavage protein matrix metalloproteinase-14. Absent decidual HIF1alpha and endostatin were observed in areas of VEGF upregulation. TGFbeta1 was present in myocytes but not in collagen bundles into which accreta trophoblast invaded. Maternal serum endoglin decreased in praevia and accreta when corrected for gestational age. CONCLUSION: Angiogenic and growth factors at the placental invasion site are altered in accreta, both by decidual absence and within myometrial scar. We postulate this promotes the invasive phenotype of placenta accreta by activating hyperinvasive trophoblast and by dysregulating placental vascular remodelling.

PMID- 29469946 TI - Genome Variations of Evolved Escherichia coli ET8 With a Rhodopsin-Based Phototrophic Metabolism. AB - We reported that the phototrophic metabolism via plasmid-originated Gloeobacter rhodopsin(GR)-expression is improved in Escherichia coli ET5 harboring pKJ606-GR by a genomic point mutation (dgcQC1082A ) encoding a transmembrane cell signaling protein (Microb. Cell Fact. 16:111, 2017). Another evolved descendant is isolated from the chemostat, and the genome variation of the strain named ET8 harboring pKJ606-GR is investigated in this study. Whole genome sequencing analysis identifies a single point mutation (C3831976A) located in the non-coding upstream region of kdtA and an IS4 insertional mutation at galUG706 without any mutations in the plasmid. ET8 strain shows enhanced kdtA transcription and no growth in the D-galactose or lactose sole carbon sourced minimal media. Size of ET8 strain are almost identical to that of the ancestor. Phototrophic growth and proton pumping in ET8 expressing GR (ET8 + GR) are increased 1.5-fold and threefold, respectively, compared with those in the ancestor (W3110 + GR). To verify the effects of the genomic mutations, either the kdtA-upregulation or the galU disruption is conducted in the ancestor. Both the kdtA-upregulation and the galU disruption result in the drastic increases of proton-pumping. The physiological properties arising from the genomic variations of the evolved host with the new phototrophic metabolism are further discussed.

AB - The NanoCulture Plate (NCP) is a novel microstructural plate designed as a base for the three-dimensional culture of cells/tissues. This study examined whether or not the metabolic capability of human primary hepatocytes is well maintained during culture on NCPs. The hepatocytes formed aggregates after seeding and their ATP content was well maintained during culture for 21 days. Expression of CYP1A2, 2B6, 2C9, 2C19, 2D6, 2E1 and 3A4 mRNAs was detected throughout the 21-day culture period. Addition of CYP substrate drugs (midazolam, diclofenac, lamotrigine and acetaminophen) resulted in the formation of multiple metabolites with a corresponding decrease in the amounts of the unchanged compounds. The inducers omeprazole, phenobarbital and rifampicin increased the levels of CYP1A2, 2B6 and 3A4 mRNAs by 110-fold, 12.5-fold and 5.4-fold, respectively, at day 2, compared with control human hepatocytes. CYP activities were also increased at 2 days after inducer treatment (CYP1A2, 2.2-fold; CYP2B6, 20.6-fold; CYP3A4, 3.3-fold). The results indicate that the hepatocyte spheroids on NCP have detectable and inducible metabolic abilities during the 7-day culture period. PMID- 29469948 TI - Sensory Acceptability of Iron-Fortified Red Lentil (Lens culinaris Medik.) Dal. AB - : Panelists in Saskatoon, Canada (n = 45) and Dhaka, Bangladesh (n = 98) participated in sensory evaluations of the sensory properties of both cooked and uncooked dehulled red lentil dal fortified with FeSO4 .7H2 O, NaFeEDTA or FeSO4 .H2 O at fortificant Fe concentrations of 800, 1,600 (both cooked and uncooked), or 2,800 ppm. Appearance, odor, and overall acceptability of cooked and uncooked samples were rated using a 9-point hedonic scale (1 = dislike extremely to 9 = like extremely). Taste and texture were rated for the cooked samples prepared as typical south Asian lentil meals. Significant differences in sensory quality were observed among all uncooked and cooked samples at both locations. Overall, scores for all sensory attributes and acceptability of uncooked lentil decreased with increasing concentration of Fe in the fortificant; however, Fe fortification (particularly with NaFeEDTA) had small effects on acceptability. Panelists from Saskatoon provided a wider range of scores than those from Bangladesh for all attributes of cooked lentil. Overall, sensory evaluation of Fe fortification using NaFeEDTA minimally affected consumer perception of color, taste, texture, odor, and overall acceptability of cooked lentil. Reliability estimates (Cronbach's alpha [CA]) indicated that consumer scores were generally consistent for all attributes of all lentil samples (mean CA > 0.80). NaFeEDTA was found to be the most suitable Fe fortificant for lentil based on consumer acceptability. Consumption of 45 to 50 g of NaFeEDTA-fortified lentil (fortificant Fe concentration of 1,600 ppm) per day meets the estimated average requirements (EARs) of Fe for humans (10.8 to 29.4 mg). PRACTICAL APPLICATION: Iron fortification of dehulled lentil dal may change organoleptic attributes that can influence consumer acceptability. Sensory evaluation by consumers helps to determine the effect on appearance, odor, taste, texture, and overall acceptability of fortified lentils. In this study, consumer acceptability was evaluated with panelists who consume lentil regularly. Panelists provided significantly different scores for 5 sensory attributes for 10 uncooked and 3 cooked lentil samples. Panelists reliably preferred NaFeEDTA as the most suitable Fe fortificant for dehulled lentils for 5 attributes. Overall, lentil dal fortified with NaFeEDTA can offer a simple and low-cost solution to human health problems associated with iron-related malnutrition. PMID- 29469949 TI - Safety profile of avelumab in patients with advanced solid tumors: A pooled analysis of data from the phase 1 JAVELIN solid tumor and phase 2 JAVELIN Merkel 200 clinical trials. AB - BACKGROUND: Antibodies targeting the programmed death-ligand 1 (PD-L1)/programmed cell death protein 1 (PD-1) checkpoint may cause adverse events (AEs) that are linked to the mechanism of action of this therapeutic class and unique from those observed with conventional chemotherapy. METHODS: Patients with advanced solid tumors who were enrolled in the phase 1 JAVELIN Solid Tumor (1650 patients) and phase 2 JAVELIN Merkel 200 (88 patients) trials received avelumab, a human anti PD-L1 IgG1 antibody at a dose of 10 mg/kg every 2 weeks. Treatment-related AEs (TRAEs) were graded using the National Cancer Institute Common Terminology Criteria for Adverse Events (version 4.0). In post hoc analyses, immune-related AEs (irAEs) were identified via an expanded AE list and medical review, and infusion-related reactions (IRRs) occurring <=2 days after infusion and symptoms occurring <=1 day after infusion and resolving <=2 days after onset were identified based on prespecified Medical Dictionary for Regulatory Activities (MedDRA) terms. RESULTS: Of the 1738 patients analyzed, grade >=3 TRAEs occurred in 177 (10.2%); the most common were fatigue (17 patients; 1.0%) and IRR (10 patients; 0.6%). TRAEs led to discontinuation in 107 patients (6.2%) and death in 4 patients (0.2%). Grade >=3 irAEs occurred in 39 patients (2.2%) and led to discontinuation in 34 patients (2.0%). IRRs or related symptoms occurred in 439 patients (25.3%; grade 3 in 0.5% [9 patients] and grade 4 in 0.2% [3 patients]). An IRR occurred at the time of first infusion in 79.5% of 439 patients who had an IRR, within the first 4 doses in 98.6% of 439 patients who had an IRR, and led to discontinuation in 35 patients (2.0%). CONCLUSIONS: Avelumab generally was found to be well tolerated and to have a manageable safety profile. A minority of patients experienced grade >=3 TRAEs or irAEs, and discontinuation was uncommon. IRRs occurred mainly at the time of first infusion, and repeated events were infrequent. Cancer 2018;124:2010-7. (c) 2018 The Authors.

PMID- 29469950 TI - Stabilization of the Pentazolate Anion in Three Anhydrous and Metal-Free Energetic Salts. AB - According to previous reports, metal cations or water molecules are necessary for the stabilization of pentazolate anion (cyclo-N5- ) at ambient temperature and pressure. Seeking a new method to stabilize N5- is a big challenge. In this work, three anhydrous, metal-free energetic salts based on cyclo-N5- 3,9-diamino-6,7 dihydro-5 H-bis([1,2,4]triazolo)[4,3-e:3',4'-g][1,2,4,5] tetrazepine-2,10-diium, N-carbamoylguanidinium, and oxalohydrazinium (oxahy+ ) pentazolate were synthesized and isolated. All salts were characterized by elemental analysis, IR spectroscopy, 1 H, 13 C, and (in some cases) 15 N NMR spectroscopy, thermal analysis (TGA and DSC), and single-crystal XRD analysis. Computational studies associated with heats of formation and detonation performance were performed by using Gaussian 09 and Explo5 programs, respectively. The sensitivity of the salts towards impact and friction was determined, and overall the real N5 explosives showed promising energetic properties. PMID- 29469951 TI - The minimal clinically important difference of the Richmond Agitation-Sedation Scale in patients with cancer with agitated delirium. AB - BACKGROUND: The Richmond Agitation-Sedation Scale (RASS) is commonly used to assess psychomotor activity; however, to the authors' knowledge, its minimal clinically important difference (MCID) has not been determined to date. The objective of the current study was to identify the MCID for RASS using 2 anchor based approaches. METHODS: The current study was a secondary analysis of a randomized controlled trial to compare the effect of lorazepam versus placebo as an adjuvant to haloperidol for persistent agitation in patients with delirium. The primary outcome was change in RASS (10-point numeric rating scale ranging from -5 [unarousable] to +4 [combative]) from baseline to 8 hours after treatment administration. The sensitivity-specificity and within-patient change methods were used to identify the MCID, with the anchor being patient comfort after the study intervention as perceived by caregivers and nurses. RESULTS: A total of 90 patients were randomized and 58 (64%) received the study medication for restlessness/agitation (mean baseline RASS, 1.6). A total of 23 caregivers (61%) and 23 nurses (55%) perceived that the patient was more comfortable after treatment. Using the sensitivity-specificity method, the optimal RASS reduction was >=4 points according to both caregivers (sensitivity of 61% and specificity of 80%; area under the curve, 0.71) and nurses (sensitivity of 73% and specificity of 84%; area under the curve, 0.78). The RASS cutoff value based on the within-patient change method was similar (-4.2 for caregivers and -4.0 for nurses). CONCLUSIONS: For patients with persistent restlessness/agitation, a reduction of >=4 points in RASS was considered to be the MCID for both nurses and caregivers. These preliminary findings may have implications for sample size calculation and the interpretation of treatment effect in future delirium trials. Cancer 2018;124:2246-52.

AB - ABCD1 is a gene responsible for X-linked adrenoleukodystrophy (X-ALD), and is critical for the transport of very long-chain fatty acids (VLCFA) into peroxisomes and subsequent beta-oxidation. VLCFA-containing lipids accumulate in X-ALD patients, although the effect of ABCD1-deficiency on each lipid species in the central nervous system has not been fully characterized. In this study, each phospholipid and lysophospholipid species in Abcd1-deficient mice brains were profiled by liquid chromatography-mass spectrometry. Among the phospholipid and lysophospholipid species that are significantly more enriched in Abcd1-deficient mice brains, VLCFA were present in 75, 15, 5, 4, and 1 species of phosphatidylcholine, phosphatidylethanolamine, sphingomyelin, lysophosphatidylcholine, and lysophosphatidylethanolamine, respectively. Most VLCFA were incorporated at the sn-1 position of phosphatidylcholine and phosphatidylethanolamine. Among the phospholipid species that are significantly less enriched in Abcd1-deficient mice brains, odd-numbered saturated or mono unsaturated fatty acyl moieties are contained in all phosphatidylcholine species. In addition, a number of phosphatidylglycerol, phosphatidylinositol, and phosphatidylserine species contained highly unsaturated fatty acyl moieties. Intriguingly, 44:1 phosphatidylcholine with VLCFA was mainly distributed in the gray matter, such as the cortex, but not in the white matter in the cerebrum and cerebellum. These results show that ABCD1-deficiency causes metabolic alternation of long-chain fatty acids and VLCFA. Moreover, our results imply a molecular mechanism for the incorporation of saturated or monounsaturated VLCFA into the sn 1 position of phospholipids, and also indicate that the distribution of phospholipids with VLCFA may correlate with the development of X-ALD. PMID- 29469953 TI - Risk stratification using lean body mass in patients undergoing transcatheter aortic valve replacement. AB - BACKGROUND: The prognostic impact of skeletal muscle mass, assessed using lean body mass (LBM), remain unclear in patients who underwent transcatheter aortic valve replacement (TAVR). The aim of this study to assess prognostic impact of LBM on mortality after TAVR. METHODS: We assessed 1,613 patients (median age 85 years, 70% female) who underwent TAVI from October 2013 to April 2016 using OCEAN (Optimized transCathEter vAlvular interveNtion)-TAVI registry data. LBM was calculated using the James formula. The primary endpoint was all-cause death after TAVR. RESULTS: Median follow-up period was 287 days (interquartile range 110-462). The Kaplan-Meier analysis demonstrated that patients with low LBM had significantly higher incidence of all-cause death than those with high LBM in male (32.3% vs. 9.9%, log rank P < 0.001) and female (15.8% vs. 9.2%, log-rank P = 0.011). On contrary, the risk stratification using body mass index (BMI) could not validate into female patients who underwent TAVR. The multivariate analysis showed that the LBM was an independent predictor of all-cause death in male (Hazard ratio [HR] 0.93; 95% confidence interval [CI] 0.89-0.98) and female (HR 0.94; 95% CI 0.89-0.99). Inversely, the assessment using BMI could not identify the high-risk population in a female. CONCLUSIONS: The patients with low LBM had the higher incidence of all-cause death after TAVR than those with high LBM, regardless of gender. Thus, the risk stratification using LBM might provide further insight to identify the high-risk TAVR population, compared to conventional risk stratification using BMI. PMID- 29469954 TI - Apremilast Alters Behavioral Responses to Ethanol in Mice: II. Increased Sedation, Intoxication, and Reduced Acute Functional Tolerance. AB - BACKGROUND: In our companion paper, we reported that the phosphodiesterase type 4 inhibitor apremilast reduced ethanol (EtOH) intake and preference in different drinking models in male and female C57BL/6J mice. In this study, we measured the effects of apremilast on other behaviors that are correlated with EtOH consumption. METHODS: The effects of apremilast (20 mg/kg) on the following behaviors were studied in male and female C57BL/6J mice: locomotor response to a novel situation; EtOH- and lithium chloride (LiCl)-induced conditioned taste aversion (CTA) to saccharin; conditioned place preference (CPP) and conditioned place avoidance (CPA) to EtOH; severity of handling-induced convulsions after EtOH administration; EtOH-induced anxiolytic-like behavior in the elevated plus maze; duration of EtOH-induced loss of righting reflex (LORR); recovery from EtOH induced motor impairment on the rotarod; and acute functional tolerance (AFT) to EtOH's ataxic effects. RESULTS: Apremilast did not change the acquisition of EtOH induced CPP, severity of acute withdrawal from EtOH, or EtOH's anxiolytic-like effect. Apremilast did not alter the extinction of EtOH- or LiCl-induced CTA, but may interfere with acquisition of CTA to EtOH. Apremilast increased the acquisition of CPA to EtOH, reduced locomotor responses to a novel situation, and prolonged the duration of LORR and the recovery from acute motor incoordination induced by EtOH. The longer recovery from the ataxic effect may be attributed to reduced development of AFT to EtOH. CONCLUSIONS: Our results suggest that apremilast increases the duration of EtOH intoxication by reducing AFT. Apremilast also reduces some aspects of general reward and increases EtOH's aversive properties, which might also contribute to its ability to reduce EtOH drinking. PMID- 29469955 TI - Variability of Symmetric Dimethylarginine in Apparently Healthy Dogs. AB - BACKGROUND: Symmetric dimethylarginine (SDMA) is a screening tool for early kidney dysfunction and monitoring treatment in cases of chronic kidney disease (CKD). There are no current studies describing the suitability of this test for use with published population-based reference intervals. HYPOTHESIS/OBJECTIVES: To determine the components of biological variability, the index of individuality (IOI), the critical difference between sequential measurements (CD ) and the number of measurements required to assess the homeostatic set point (HSP), for both SDMA and serum creatinine (sCr), in apparently healthy dogs. ANIMALS: Twenty apparently healthy adult dogs owned by clients or staff at a veterinary teaching hospital. METHODS: Prospective, observational study. Blood was collected from each dog on 9 occasions, and SDMA and sCr were measured in duplicate using commercially available assays. RESULTS: SDMA and sCr had intermediate and low IOI values of 0.87 and 0.28, respectively. The CD of SDMA and sCr, was 1.34 ug/dL and 0.89 umol/L, respectively. The sample numbers required for estimation of an individual's HSP (with 90 and 95% CI) for SDMA and sCr were 8 and 45, and 2 and 12 sequential measurements, respectively. CONCLUSIONS AND CLINICAL IMPORTANCE: Based on our findings, in comparison to sCr, SDMA is better suited for use with population-based reference intervals. False-negative test results could occur when comparing a single test result from an individual to such intervals. Ideally CD should be used with sequential measurements. PMID- 29469956 TI - IFN-gamma orchestrates tumor elimination, tumor dormancy, tumor escape, and progression. AB - Tumor immunoediting consisting of three phases of elimination, equilibrium or dormancy, and escape has been supported by preclinical and clinical data. A comprehensive understanding of the molecular mechanisms by which antitumor immune responses regulate these three phases are important for developing highly tailored immunotherapeutics that can control cancer. To this end, IFN-gamma produced by Th1 cells, cytotoxic T cells, NK cells, and NKT cells is a pleiotropic cytokine that is involved in all three phases of tumor immunoediting, as well as during inflammation-mediated tumorigenesis processes. This essay presents a review of literature and suggests that overcoming tumor escape is feasible by driving tumor cells into a state of quiescent but not indolent dormancy in order for IFN-gamma-producing tumor-specific T cells to prevent tumor relapse. PMID- 29469957 TI - The Effect of Urine Concentration and pH on the Growth of Escherichia Coli in Canine Urine In Vitro. AB - BACKGROUND: Lower urinary tract infections are common in dogs, and Escherichia coli is the most common bacterial pathogen isolated. The literature has conflicting evidence regarding the inhibitory effects of urine concentration and pH on E. coli growth. HYPOTHESIS/OBJECTIVES: To determine the effect of different pH and urine concentrations on E. coli growth in vitro. ANIMALS: Voided urine samples from 10 apparently healthy spayed female dogs were used. METHODS: A matrix of 9 urine specific gravity (USG; 1.010, 1.020, and 1.030) and pH (5.5, 7.0, and 8.5) combinations was prepared by diluting and titrating filtered voided urine samples. Three E. coli isolates were obtained from urine of female dogs with signs of lower urinary tract infection and cultured at different urine pH and USG combinations in wells of a microtiter plate. The number of E. coli colony forming units (CFU) per mL of urine was calculated after aerobic incubation of the urine at 37 degrees C for 18 hours, and statistically compared. RESULTS: Significant differences were identified in the mean log CFU/mL among different combinations of pH and USG. The lowest log CFU/mL were observed in alkaline concentrated urine (pH 8.5 and USG 1.030). CONCLUSIONS AND CLINICAL IMPORTANCE: Escherichia coli in vitro growth was higher in neutral to acidic and diluted urine compared to alkaline and concentrated urine. The impact of non-alkalizing diluting diets on the incidence of E. coli lower urinary tract infections should be further explored. PMID- 29469958 TI - Long-term experience with intranasal bevacizumab therapy. AB - OBJECTIVES/HYPOTHESIS: Long-term follow-up of intranasal bevacizumab therapy in hereditary hemorrhagic telangiectasia (HHT). STUDY DESIGN: Prospective, noncomparative study. METHODS: Patients treated for HHT-associated epistaxis by intranasal submucosal bevacizumab injections between June 2011 and August 2013 were included and followed prospectively. The effectiveness of the treatment was evaluated by the epistaxis severity score (ESS); the epistaxis intensity, frequency, and the need of blood transfusion (IFT) score; and hemoglobin levels. RESULTS: Thirty-three patients were included. The total number of treatments with intranasal bevacizumab injection was 210. The mean number of treatments per patient was 6.2 +/- 4.6 (range, 1-16), and the mean treatment and observation period was 38.8 +/- 21.8 months (range, 2-66 months). Four patients showed no improvement after treatment. Eleven patients (33.3%) showed initial improvement in both ESS and IFT, but the treatment was discontinued before the end of the study because the effect became gradually shorter lasting despite repeated injections. Twelve patients (36.3%) continued to have a positive response to the treatment at the end of the study. No local adverse effects were observed, but one patient developed osteonecrosis in both knees during the treatment period. CONCLUSIONS: Intranasal bevacizumab injection is an effective treatment for most of the moderate and severe grades of HHT-associated epistaxis. The duration of the effect of the treatment was variable. Primary and late resistance phenomena to the treatment were quite common. LEVEL OF EVIDENCE: 4. Laryngoscope, 128:2237 2244, 2018.

AB - BACKGROUND: Nuclear factor erythroid 2-like 2 (NFE2L2) encodes Nrf2, transcription factor of antioxidative genes. In the presence of reactive oxygen species, Keap1 (Kelch-ECH-associating protein-1) inhibitor complex undergoes conformational changes disrupting Keap1-Nrf2 binding and Nrf2 translocates into nucleus. We evaluated the presence of mutations in NFE2L2 and KEAP1 in papillary thyroid carcinomas (PTCs) and correlated them with clinical presentation. METHODS: Coding regions of NFE2L2 and KEAP1 were sequenced in 131 patients with PTC. Clinical and histopathological features were analyzed. Immunohistochemical analysis of Nrf2 expression was performed in mutated carcinomas. RESULTS: Although no mutations were found in NFE2L2, missense mutations in KEAP1 were observed in 6 patients with PTC (4.6%). Immunohistochemistry showed increased Nrf2 expression in nuclei of all mutated carcinomas, which presented poor prognostic features in histopathology. CONCLUSION: We identified mutations in KEAP1 associated with Nrf2 overexpression in PTC. Mutations favored disruption of inhibitory interaction Nrf2-Keap1 to enable increased antioxidant Nrf2 activity, possibly with prognostic consequences. PMID- 29469960 TI - Ultra-Performance Liquid Chromatography-Mass Spectrometry Analysis of Free and Esterified Oxygenated Derivatives from Docosahexaenoic Acid in Rat Brain. AB - Docosahexaenoic acid (DHA), a prominent long-chain fatty acid of the omega-3 family, is present at high amount in brain tissues, especially in membrane phospholipids. This polyunsaturated fatty acid is the precursor of various oxygenated lipid mediators involved in diverse physiological and pathophysiological processes. Characterization of DHA-oxygenated metabolites is therefore crucial for better understanding the biological roles of DHA. In this study, we identified and measured, by ultrahigh-performance liquid chromatography coupled with tandem mass spectrometry, a number of oxygenated products derived from DHA in exsanguinated and nonexsanguinated brains. These metabolites were found both in free form and esterified in phospholipids. Interestingly, both (R)- and (S)-monohydroxylated fatty acid stereoisomers were observed free and esterified in phospholipids. Monohydroxylated metabolites were the main derivatives; however, measurable amounts of dihydroxylated products such as protectin DX were detected. Moreover, exsanguination allowed discriminating brain oxygenated metabolites from those generated in blood. These results obtained in healthy rats allowed an overview on the brain oxygenated metabolism of DHA, which deserves further research in pathophysiological conditions, especially in neurodegenerative diseases.

AB - BACKGROUND: Despite recent advances in allogeneic hematopoietic stem cell transplantation (AHSCT), the outcome of patients who have acute myeloid leukemia (AML) with a complex karyotype (CK) remains poor. The objective of this study was to identify prognostic factors associated with post-transplantation survival in a large cohort of patients with CK AML. METHODS: In total, data on 1342 consecutively patients who underwent transplantation for CK (>=3 chromosomal abnormalities) AML were provided by the Acute Leukemia Working Party of the European Society for Blood and Marrow Transplantation and from the University of Texas MD Anderson Cancer Center database were included in the analysis. The median patient age was 52 years. The donors were human leukocyte antigen-matched related donors (N = 749), matched unrelated donors (N = 513), and mismatched unrelated donors (N = 80). RESULTS: Relapse was the main cause of treatment failure. Overall, 51% of patients relapsed, 17.6% died of treatment-related mortality, and 31.3% survived leukemia-free. In multivariate analysis, the factors associated with an increased risk of relapse were age (>40 years; hazard ratio [HR], 1.1 per 10 years; P = .02), secondary AML (HR, 1.35; P = .01), active disease at transplantation (HR, 1.98; P < .001), and deletion/monosomy 5 (HR, 1.5; P < .001); whereas age (HR, 1.15 per 10 years; P < .001), secondary AML (HR, 1.36; P = .001), active disease at transplantation (HR, 1.99; P < .001), deletion/monosomy 5 (HR, 1.24; P = .008), and deletion/monosomy 7 (HR, 1.44; P < .001) predicted for leukemia-free survival. CONCLUSIONS: Disease relapse remains the most common cause of treatment failure for patients with CK AML after transplantation. Novel approaches to decrease the relapse rate and improve survival are needed in these patients. Cancer 2018;124:2134-41. (c) 2018 American Cancer Society.

AB - The distance dependence of electron transfer (ET) is commonly investigated in linear rigid rod-like compounds, but studies of molecular wires with integrated corners imposing 90 degrees angles are very rare. By using spirobifluorene as a key bridging element and by substituting it at different positions, two isomeric series of donor-bridge-acceptor compounds with either nearly linear or angled geometries were obtained. Photoinduced ET in both series is dominated by rapid through-bond hole hopping across oligofluorene bridges over distances of up to 70 A. Despite considerable conformational flexibility, direct through-space and through-solvent ET is negligible even in the angled series. The independence of the ET rate constant on the total number of fluorene units in the angled series is attributed to a rate-limiting tunneling step through the spirobifluorene corner. This finding is relevant for multidimensional ET systems and grids in which individual molecular wires are interlinked at 90 degrees angles. PMID- 29469962 TI - Apremilast Alters Behavioral Responses to Ethanol in Mice: I. Reduced Consumption and Preference. AB - BACKGROUND: Phosphodiesterase type 4 (PDE4) inhibitors produce widespread anti inflammatory effects and reduce ethanol (EtOH) consumption in several rodent models. These drugs are potential treatments for several diseases, including central nervous system disorders, but clinical use is limited by their emetic activity. Apremilast is a selective PDE4 inhibitor with fewer gastrointestinal side effects that is FDA-approved for the treatment of psoriasis. METHODS: We measured the acute and chronic effects of apremilast on EtOH consumption in male and female C57BL/6J mice using the continuous and intermittent 24-hour 2-bottle choice drinking models. We also studied the effects of apremilast on preference for sucrose or saccharin, spontaneous locomotor activity, and blood EtOH clearance. Finally, apremilast levels in plasma, liver, and brain were measured 1 or 2 hours after injection. RESULTS: In the continuous and intermittent drinking tests, apremilast (15 to 50 mg/kg, p.o.) dose dependently reduced EtOH intake and preference in male and female mice. Higher doses of apremilast (30 to 50 mg/kg) also reduced total fluid intake in these mice. Chronic administration of apremilast (20 mg/kg) produced a stable reduction in EtOH consumption in both drinking tests with no effect on total fluid intake. The drinking effects were reversible after drug treatment was replaced with vehicle administration (saline) for 2 to 4 days. Six daily apremilast injections did not alter preference for saccharin or sucrose in male or female mice. Apremilast (20 mg/kg) transiently decreased spontaneous locomotor activity and did not alter blood EtOH clearance. The highest levels of apremilast were found in liver followed by plasma and brain. CONCLUSIONS: Apremilast produced stable reductions in voluntary EtOH consumption and was rapidly distributed to plasma and tissues (including the brain), suggesting that it may be an improved PDE4 inhibitor for medication development and repurposing efforts to treat alcohol abuse. PMID- 29469964 TI - Impact of SLCO1B1 Genotype on Pediatric Simvastatin Acid Pharmacokinetics. AB - This study investigated the impact of allelic variation in SLCO1B1, a gene encoding for the liver-specific solute carrier organic anion transporter family member 1B1 protein (SLCO1B1), on simvastatin and simvastatin acid (SVA) systemic exposure in children and adolescents. Participants (8-20 years old) with at least 1 variant SLCO1B1 c.521T>C allele (521TC, n = 15; 521CC, n = 2) and 2 wild-type alleles (521TT, n = 15) completed a single oral dose pharmacokinetic study. At equivalent doses, SVA exposure was 6.3- and 2.5-fold greater in 521CC and TC genotypes relative to 521TT (Cmax , 2.1 +/- 0.2 vs 1.0 +/- 0.5 vs 0.4 +/- 0.3 ng/mL; P < .0001; and AUC, 12.1 +/- 0.3 vs 4.5 +/- 2.5 vs 1.9 +/- 1.8 ng.h/mL; P < .0001). The impact of the SLCO1B1 c.521 genotype was more pronounced in children, although considerable interindividual variability in SVA exposure was observed within genotype groups. In addition, SVA systemic exposure was negligible in 25% of pediatric participants. Further investigation of the ontogeny and genetic variation of SVA formation and SLCO1B1-mediated hepatic uptake is necessary to better understand the variability in SVA exposure in children and its clinical consequences. PMID- 29469966 TI - The effect of skin surface topography and skin colouration cues on perception of male facial age, health and attractiveness. AB - OBJECTIVE: Previous studies investigating the effects of skin surface topography and colouration cues on the perception of female faces reported a differential weighting for the perception of skin topography and colour evenness, where topography was a stronger visual cue for the perception of age, whereas skin colour evenness was a stronger visual cue for the perception of health. We extend these findings in a study of the effect of skin surface topography and colour evenness cues on the perceptions of facial age, health and attractiveness in males. METHODS: Facial images of six men (aged 40 to 70 years), selected for co expression of lines/wrinkles and discolouration, were manipulated digitally to create eight stimuli, namely, separate removal of these two features (a) on the forehead, (b) in the periorbital area, (c) on the cheeks and (d) across the entire face. Omnibus (within-face) pairwise combinations, including the original (unmodified) face, were presented to a total of 240 male and female judges, who selected the face they considered younger, healthier and more attractive. RESULTS: Significant effects were detected for facial image choice, in response to skin feature manipulation. The combined removal of skin surface topography resulted in younger age perception compared with that seen with the removal of skin colouration cues, whereas the opposite pattern was found for health preference. No difference was detected for the perception of attractiveness. These perceptual effects were seen particularly on the forehead and cheeks. Removing skin topography cues (but not discolouration) in the periorbital area resulted in higher preferences for all three attributes. CONCLUSION: Skin surface topography and colouration cues affect the perception of age, health and attractiveness in men's faces. The combined removal of these features on the forehead, cheeks and in the periorbital area results in the most positive assessments. PMID- 29469965 TI - Vitamin D Receptor Expression in Dogs. AB - BACKGROUND: There is growing evidence linking low blood vitamin D concentration to numerous diseases in people and in dogs. Vitamin D influences cellular function by signaling through the vitamin D receptor (VDR). Little is known about which non-skeletal tissues express the VDR or how inflammation influences its expression in the dog. OBJECTIVES: To define which non-skeletal canine tissues express the VDR and to investigate expression in inflamed small intestine. ANIMALS: Thirteen non-skeletal tissues were collected prospectively from 6 control dogs. Thirty-five dogs diagnosed with a chronic enteropathy (CE) and 24 control dogs were prospectively enrolled and duodenal biopsies were evaluated for VDR expression. METHODS: Prospective; blinded assessment of canine intestinal VDR. Dogs with CE were included once other identifiable causes of intestinal disease were excluded. Age matched controls were included with no intestinal clinical signs. VDR expression was assessed immunohistochemically in all samples, using a Rat IgG VDR monoclonal antibody. Quantitative real-time polymerase chain reaction (qPCR) was also used for duodenal biopsies. RESULTS: VDR expression as assessed by immunohistochemistry (IHC) was highest in the kidney, duodenum, skin, ileum and spleen, and weak in the colon, heart, lymph node, liver, lung, and ovary. Gastric and testicular tissue did not express the VDR. There was no statistical difference in duodenal VDR expression between the 24 healthy dogs and 34 dogs with CE when quantified by either qPCR (P = 0.87) or IHC (P = 0.099). CONCLUSIONS AND CLINICAL IMPORTANCE: The lack of down regulation of VDR expression in inflamed intestine contrasts with previous studies in humans. Our findings support future studies to investigate whether vitamin D and its analogues can be used to modulate intestinal inflammation in the dog. PMID- 29469968 TI - First follow-up of a breakable stent for implantation in infants dedicated for a life-long stay. AB - OBJECTIVE AND METHODS: The use of conventional metal stents in infants is severely limited by subsequent somatic growth. The use of a breakable balloon expandable stent (BS) designed for initial implant at small diameters but with properties that allow unlimited dilation in line with growth has potential advantages in this patient group. This study reports our experience with this stent between 2010 and 2014. A total of 17 BS were implanted in 14 infants (mean age 4.8 months). All but one stent was placed into the aorta to treat coarctation. RESULTS: All implantations were successful and initial gradients dropped from a mean of 25-6 mm Hg (range from 1-50 down to 0-24 mm Hg). Mean follow-up was 3.3 years (range 5 days to 7 years) with a total cumulative follow up of 46.7 patient years. Stent redilation was performed a median of 2.5 times (range 0-5). Sixteen stents in 13 patients remain in place. Following redilation beyond 10 mm, circumferential integrity of the BS was lost in 10 patients. No further stent implantation or related surgery was necessary. A 3 mm dissection occurred in one patient after redilation. CONCLUSIONS: The BS performed well in terms of relief of stenosis and could be successfully dilated during the phase of the infants' most rapid growth. Mild intimal proliferation occurred in some patients early after implantation. In the course of the stepwise redilations and growth adjustments, both, planned longitudinal and transverse fractures occurred without allowing a collapse of the stented area.

AB - The aim of the study was to investigate the metabolism of 4-fluoro-N-(1-{2 [(propan-2-yl)phenoxy]ethyl}-8-azabicyclo[3.2.1]octan-3-yl)-benzenesulfonamide (PZ-1150), a novel 5-HT7 receptor antagonist with antidepressant-like and anxiolytic properties, by the following three ways: in vitro with microsomes; in vitro employing Cunninghamella echinulata, and in silico using MetaSite. Biotransformation of PZ-1150 with microsomes resulted in five metabolites, while transformation with C. echinulata afforded two metabolites. In both models, the predominant metabolite occurred due to hydroxylation of benzene ring. In silico data coincide with in vitro experiments, as three MetaSite metabolites matched compounds identified in microsomal samples. In human liver microsomes PZ-1150 exhibited in vitro half-life of 64 min, with microsomal intrinsic clearance of 54.1 MUL/min/mg and intrinsic clearance of 48.7 mL/min/kg. Therefore, PZ-1150 is predicted to be a high-clearance agent. The study demonstrated the applicability of using microsomal model coupled with microbial model to elucidate the metabolic pathways of compounds and comparison with in silico metabolite predictions. PMID- 29469969 TI - Nanobody-Enabled Reverse Pharmacology on G-Protein-Coupled Receptors. AB - The conformational complexity of transmembrane signaling of G-protein-coupled receptors (GPCRs) is a central hurdle for the design of screens for receptor agonists. In their basal states, GPCRs have lower affinities for agonists compared to their G-protein-bound active state conformations. Moreover, different agonists can stabilize distinct active receptor conformations and do not uniformly activate all cellular signaling pathways linked to a given receptor (agonist bias). Comparative fragment screens were performed on a beta2 adrenoreceptor-nanobody fusion locked in its active-state conformation by a G protein-mimicking nanobody, and the same receptor in its basal-state conformation. This simple biophysical assay allowed the identification and ranking of multiple novel agonists and permitted classification of the efficacy of each hit in agonist, antagonist, or inverse agonist categories, thereby opening doors to nanobody-enabled reverse pharmacology. PMID- 29469970 TI - Glimepiride treatment in a patient with type A insulin resistance syndrome due to a novel heterozygous missense mutation in the insulin receptor gene. AB - AIMS/INTRODUCTION: Glimepiride is a sulfonylurea known to have unique insulin mimetic and sensitizing effects. We aimed to study the efficacy of glimepiride in a patient with type A insulin resistance syndrome. MATERIALS AND METHODS: A 15 year-old girl with type A insulin resistance syndrome was treated with glimpiride for 6 months. Self-monitoring of blood glucose was recorded, and oral glucose tolerance tests on glucose and insulin were measured during the treatment. Hyperinsulinemic euglycemic clamp was used to evaluate whole-body insulin sensitivity before and after the treatment. RESULTS: A novel heterozygous missense mutation at exon 19 (c.3427A>T) in the tyrosine kinase domain of the INSR gene was identified, causing an amino acid replacement of phenylalanine for isoleucine at codon 1143 (Ile1143Phe). Before the treatment, the patient's glycated hemoglobin was 7.0%, plasma glucose during oral glucose tolerance test was 6.7, 12.8 and 17.3 mmol/L, and simultaneous serum insulin was 80.7, 137.5 and >300 MUU/mL. There were no significant differences between self-monitored blood glucose measured at each time-point among different glimepiride dosages, or during the 14 weeks when glimepiride was used at its maximal dosage (6 mg/day). Oral glucose tolerance test showed little change in plasma glucose and serum insulin. Glycated hemoglobin decreased by 0.8% after the treatment. However, a euglycemic clamp study showed that the M value decreased from 5.25 to 2.90 mg/kg/min, showing increased insulin resistance. CONCLUSIONS: Treatment with glimepiride did not improve insulin sensitivity in a patient with type A insulin resistance syndrome carrying Ile1143Phe heterozygous mutation in the INSR gene. Large-scale long-term studies assembled worldwide are required to optimize treatment algorithms for patients with type A insulin resistance syndrome.

PMID- 29469972 TI - Cooling of the oral mucosa to prevent adverse effects of chemotherapeutic agents: An in vitro study. AB - BACKGROUND: The cytotoxic effect of chemotherapeutic agents to the oral mucosa, as a side effect of cancer treatment, is a major problem. Cooling the oral mucosa using ice chips in conjunction with chemotherapy is known to reduce the severity of oral mucositis. However, although the use of ice chips is of clinical value, this method of cooling has inherent problems including discomfort for the patient, non-uniformity and fluctuations in cooling temperature throughout the oral cavity. Furthermore, despite being used clinically, it is not known what reduction in temperature is required to prevent oral mucositis. The aim of this study was therefore to determine in vitro if the cytotoxic effect of 5 fluorouracil (5-FU) on the oral mucosa could be reduced by lowering the temperature during chemotherapeutic treatment. METHODS: Tissue-engineered oral mucosal (TEOM) models were incubated at 20, 25, 30 or 35 degrees C for 30 minutes followed by exposure to a clinically relevant concentration of 5-FU (162 MUg/mL) for 2 hours and compared with untreated models (35 degrees C). Cell viability and inflammatory cytokine production (IL-6 and TNF-alpha) were measured using PrestoBlue(r) and ELISA, respectively. RESULTS: TEOM models incubated at 20 degrees C showed an increased cell viability and had a reduced IL-6 and TNF-alpha production compared to models treated with 5-FU incubated at 35 degrees C. CONCLUSION: This study demonstrates a reduced cytotoxic effect to the TEOM by reducing the temperature of the tissue during chemotherapy treatment and suggests that decreasing the temperature to 20 degrees C could have clinical advantages. PMID- 29469974 TI - Assessment of Canine Pancreas-Specific Lipase and Outcomes in Dogs with Hemodialysis-Dependent Acute Kidney Injury. AB - BACKGROUND: Renal replacement therapies can be life-saving for dogs with severe acute kidney injury (AKI), however, comorbidities including pancreatitis might affect outcome. HYPOTHESIS/OBJECTIVES: To investigate the prevalence of pancreas specific lipase (Spec cPL) measurements consistent with pancreatitis (>=400 MUg/L) in dogs undergoing intermittent hemodialysis (IHD) for treatment of AKI and to determine whether there were associations between 30-days outcomes and Spec cPL measurements. ANIMALS: Fifty-three client-owned dogs presented to teaching hospitals between November 2008 and September 2016 that underwent IHD. METHODS: Retrospective medical record review from dogs that received IHD for management of AKI and also had a Spec cPL measurement. Association between survival, dialysis-dependency, and Spec cPL measurements was assessed. RESULTS: Forty of 53 (76%) dogs were alive at 30-days and 33/53(62%) had a Spec cPL result >=400 MUg/L. Spec cPL was not significantly different either between surviving (635.5 MUg/L, range 29-1,001) and nonsurviving dogs (860 MUg/L, range 56-1,001; P = 0.75) or between dialysis-dependent (1,001 MUg/L, range 177-1,001) and nondialysis-dependent dogs (520 MUg/L, range 29-1,001; P = 0.08). Spec cPL >=400 MUg/L was not significantly associated either with survival (P = 0.74) or dialysis-dependency (P = 0.33). CONCLUSIONS AND CLINICAL IMPORTANCE: Results revealed a high prevalence of Spec cPL >=400 MUg/L in dogs with AKI treated with IHD. No significant associations between Spec cPL and survival or dialysis dependency in dogs with AKI at 30 days were identified in the current study, however, the latter could be due to lack of power in this study.

AB - 3,4,5-Trihydroxypiperidines belong to the family of 1,5-dideoxy-1,5-iminosugar natural products and are structural analogues of pentose monosaccharides in the pyranose form. The biological activities of these apparently structurally simple molecules and their N- and O-alkylated and -arylated derivatives are no less remarkable than their C-6 hydroxymethyl counterparts of the hexoses (such as 1 deoxynojirimycin, DNJ). Their biological profiles indicate that the hydroxymethyl branch is crucial to neither potency nor selectivity, with O-alkylation demonstrated to produce exquisite selectivity extending beyond glycosidase inhibition, to immunosuppressant and antibacterial activities. PMID- 29469977 TI - Vibrio cholerae cytolysin: Multiple facets of the membrane interaction mechanism of a beta-barrel pore-forming toxin. AB - Vibrio cholerae cytolysin (VCC) is a membrane-damaging protein toxin with potent cytolytic/cytotoxic activity against wide range of eukaryotic cells. VCC is a beta-barrel pore-forming toxin (beta-PFT), and it inflicts damage to the target cell membranes by forming transmembrane heptameric beta-barrel pores. To exert pore-forming activity, VCC must bind to the cell membranes in an efficient manner. Efficient interaction with the cell membranes is an essential pre requisite to trigger subsequent structural/conformational and organizational changes in the toxin molecules leading toward formation of the transmembrane oligomeric beta-barrel pores. Based on the large numbers of studies investigating the mode of action of VCC, it is now evident that VCC is capable of using multiple distinct mechanisms to recognize and bind to the membrane components and cell surface molecules. In this review article, we present an overview of our current understanding regarding the membrane interaction mechanisms of VCC, and their functional implications for the pore-forming activity of the toxin.

AB - BACKGROUND: Hypercalcemia is commonly associated with chronic kidney disease (CKD) in cats. OBJECTIVES: To explore the calcitonin response to naturally occurring ionized hypercalcemia in cats with azotemic CKD, and to assess the relationship of plasma calcitonin with ionized calcium, alkaline phosphatase (ALP), and urinary calcium excretion. ANIMALS: Thirty-three client-owned cats with azotemic CKD and ionized hypercalcemia from first opinion practice. METHODS: Cohort study. Calcitonin was measured with an immunoradiometric assay in heparinized plasma. Simple correlations were assessed with Kendall's rank correlation, and the within-subject correlations of calcitonin with ionized calcium and other clinicopathological variables were calculated with a bivariate linear mixed effects model. RESULTS: Calcitonin concentrations above the lower limit of detection (>1.2 pg/mL; range, 1.7-87.2 pg/mL) were observed in 11 of 33 hypercalcemic cats (responders). Blood ionized calcium concentration did not differ significantly between responders (median, 1.59 [1.46, 1.66] mmol/L) and nonresponders (median, 1.48 [1.43, 1.65] mmol/L; P = 0.22). No evidence was found for calcitonin and ionized calcium to correlate between cats (taub = 0.14; P = 0.31; n = 33), but significant positive correlation was evident within individual responders over time (within-subject correlation coefficient [rwithin ], 0.83; 95% confidence interval [CI], 0.63-0.92). Calcitonin correlated negatively over time with plasma ALP (rwithin , -0.55; 95% CI, -0.79 to -0.16). CONCLUSIONS AND CLINICAL IMPORTANCE: Calcitonin does not appear to have an important role in calcium metabolism in cats with CKD. PMID- 29469978 TI - Survey of Equine Referring Veterinarians' Satisfaction with Their Most Recent Equine Referral Experience. AB - BACKGROUND: Little is known about the veterinary referral process and factors that contribute to positive outcomes. OBJECTIVE: To investigate equine referring veterinarians' (rDVMs') satisfaction with their most recent referral experience and compare rDVM and specialist perspectives. SAMPLE: 187 rDVMs and 92 specialists (referral care providers). METHODS: Cross-sectional observational study. An online survey was administered to both rDVMs and specialists. Referring veterinarian satisfaction with their most recent referral experience was evaluated. Both rDVMs and specialists were asked to identify factors influencing a rDVM's decision where to refer, and the top 3 factors they perceive are barriers to referral care. RESULTS: Median rDVM satisfaction with their most recent referral care experience was 80 of 100 (mean, 75; range, 8-100). Referring veterinarians provided the lowest satisfaction score for the item asking about "The competition the referral hospital poses to your practice" (mean, 56.96; median, 62; range, 0-100). The top factor rDVMs identified as influencing their decision where to refer was "quality of care," whereas specialists identified "quality of communication and updates from the clinician." Referring veterinarians' top barrier to referral care was "high cost of referral care," and for specialists was "poor service provided to the client by the referral hospital." CONCLUSIONS AND CLINICAL IMPORTANCE: Referring veterinarians generally were satisfied with referral care, but areas exist where rDVMs and specialists differ in what they view as important to the referral process. Exploring opportunities to overcome these differences is likely to support high quality care. PMID- 29469979 TI - Clinicians' perspective on an app for patient self-monitoring in eating disorder treatment. AB - OBJECTIVE: The Recovery Record smartphone app is a self-monitoring tool for individuals recovering from eating disorders. Oppositely to traditional pen-and paper meal diaries, the app allows for in-app patient-clinician linkage enabling clinicians to access patient app data anytime. The aim of our study was to explore the interdisciplinary clinical perspective on Recovery Record and its impact on treatment. METHOD: Thirty-one clinicians from a Danish eating disorder treatment facility participated in field studies and 23 of these in interviews. Data were generated and analyzed concurrently applying the inductive methodology of Interpretive Description. RESULTS: We found two overarching themes: "Access to app data between treatment sessions", and "The patient-clinician relationship". Sub-themes associated with the former were "Online obligations" in relation to the added workload of continuously monitoring patient app data, and "Prepared or prejudiced" relating to advantages and disadvantages of using patient app data as preparation for treatment sessions. Sub-themes pertaining to the latter were "Expectation discrepancy" in relation to patients' and clinicians' divergent expectations for app usage, and "Pacified patients" regarding the clinicians' experience that the app potentially compromised the patient initiative in treatment sessions. DISCUSSION: Recovery Record induced new and affected pre existing treatment and work conditions for clinicians. Clinicians were preoccupied with challenges associated with the app, for example, an added work load and potential harm to the patient-clinician collaboration. Thus, prior to adopting the app, we encourage clinicians and managements to discuss the objectives, advantages and disadvantages of adopting the app, and outline specific guidelines for patient and clinician app usage. PMID- 29469980 TI - Discovery of thiophene-containing biaryl amide derivatives as novel glucagon receptor antagonists. AB - A novel series of thiophene-containing biaryl amide glucagon receptor (GCGR) antagonists were designed and synthesized. Two compounds of this series, 14f and 14h, exhibited good GCGR binding (IC50 = 6.1 and 4.4 MUm, respectively) and cAMP functional activities (IC50 = 4.4 and 14.4 MUm, respectively). The possible binding modes of compounds 14f and 14h with GCGR were explored by molecular simulation. PMID- 29469981 TI - Moisture availability limits subalpine tree establishment. AB - In the absence of broad-scale disturbance, many temperate coniferous forests experience successful seedling establishment only when abundant seed production coincides with favorable climate. Identifying the frequency of past establishment events and the climate conditions favorable for seedling establishment is essential to understanding how climate warming could affect the frequency of future tree establishment events and therefore future forest composition or even persistence of a forest cover. In the southern Rocky Mountains, USA, research on the sensitivity of establishment of Engelmann spruce (Picea engelmannii) and subalpine fir (Abies lasiocarpa)-two widely distributed, co-occurring conifers in North America-to climate variability has focused on the alpine treeline ecotone, leaving uncertainty about the sensitivity of these species across much of their elevation distribution. We compared annual germination dates for >450 Engelmann spruce and >500 subalpine fir seedlings collected across a complex topographic moisture gradient to climate variability in the Colorado Front Range. We found that Engelmann spruce and subalpine fir established episodically with strong synchrony in establishment events across the study area. Broad-scale establishment events occurred in years of high soil moisture availability, which were characterized by above-average snowpack and/or cool and wet summer climatic conditions. In the recent half of the study period (1975-2010), a decrease in the number of fir and spruce establishment events across their distribution coincided with declining snowpack and a multi-decadal trend of rising summer temperature and increasing moisture deficits. Counter to expected and observed increases in tree establishment with climate warming in maritime subalpine forests, our results show that recruitment declines will likely occur across the core of moisture-limited subalpine tree ranges as warming drives increased moisture deficits.

AB - The alleviative effects of two antioxidants, carnosine (Car) and melatonin (Mel), against titanium dioxide nanoparticles (TiO2 -NPs) toxicity-induced oxidative and inflammatory renal damage were examined in rats. Administration of these antioxidants along with TiO2 -NPs effectively reduced serum urea, uric acid, creatinine, glucose, tumor necrosis factor-alpha, interleukin-6, C-reactive protein, immunoglobulin G, vascular endothelial growth factor, and nitric oxide, as well as a significant amelioration of the decrease in glutathione levels in renal tissue was observed, compared to those in rats treated with TiO2 -NPs alone. The renoprotective properties of the antioxidants were confirmed by reduced intensity of renal damage as demonstrated by histological findings. In conclusion, Car and Mel play protective roles against TiO2 -NPs-induced renal inflammation and oxidative injury, likely due to their antioxidant and anti inflammatory properties. PMID- 29469983 TI - Identification of 4-aryl-1H-pyrrole[2,3-b]pyridine derivatives for the development of new B-Raf inhibitors. AB - During the last years, a significant interest in the identification of new classes of B-Raf inhibitors has emerged. In this study, which was conceived within an effort that culminated in the recent report of the first dual inhibitors of B-Raf and Hsp90, we describe the identification of four compounds based on 4-aryl-1H-pyrrole[2,3-b]pyridine scaffold as interesting starting points for the development of new B-Raf inhibitors. Structure-activity relationships and predicted binding modes are discussed. Moreover, the novelty of the newly identified structures with respect to currently known B-Raf inhibitors was assessed through a ligand-based dissimilarity assessment. Finally, structural modifications with the potential ability to improve the activity toward B-Raf are put forward.

AB - Aortic annular rupture is one of the most feared complications of transcatheter aortic valve replacement (TAVR). This complication often presents as sudden cardiac tamponade with hypotension and requires urgent intervention. The traditional rescue strategy for such cases is emergency surgical intervention, yet the mortality remains high considering most patients who undergo TAVR are not candidates for open heart surgery. As such, there is a need for percutaneous alternatives to treat this critical complication. Here, we describe a case of annular rupture during TAVR that was successfully treated with coil embolization at the rupture site. This case illustrates the use of coil embolization as a treatment strategy in patients with acute aortic annular rupture who are at high risk for surgical intervention. PMID- 29469985 TI - Bis-2(5H)-furanone derivatives as new anticancer agents: Design, synthesis, biological evaluation, and mechanism studies. AB - New bis-2(5H)-furanone derivatives containing a benzidine core were synthesized via a one-step transition-metal-free reaction of benzidine with 5-substituted 3,4 dihalo-2(5H)-furanones. Their antitumor activities against various tumor cells have been evaluated by MTT assay. Among them, compound 4e exhibits significant inhibitory activity against C6 glioma cells with an IC50 value of 12.1 MUm and low toxicity toward HaCaT human normal cells. Studies on the antitumor mechanism reveal that cell cycle arrest at S-phase in C6 cells is induced by compound 4e. Furthermore, investigations with electronic, fluorescence emission and circular dichroism spectra show that compound 4e can significantly interact with C6-DNA. These data indicate that DNA may be one of the potential targets for bis-2(5H) furanone derivatives as anticancer drugs. PMID- 29469987 TI - Magnetic Reduced Graphene Oxide/Nickel/Platinum Nanoparticles Micromotors for Mycotoxin Analysis. AB - Magnetic reduced graphene oxide/nickel/platinum nanoparticles (rGO/Ni/PtNPs) micromotors for mycotoxin analysis in food samples were developed for food-safety diagnosis. While the utilization of self-propelled micromotors in bioassays has led to a fundamentally new approach, mainly due to the greatly enhanced target receptor contacts owing to their continuous movement around the sample and the associated mixing effect, herein the magnetic properties of rGO/Ni/PtNPs micromotors for mycotoxin analysis are additionally explored. The micromotor based strategy for targeted mycotoxin biosensing focused on the accurate control of micromotor-based operations: 1) on-the-move capture of free aptamers by exploiting the adsorption (outer rGO layer) and catalytic (inner PtNPs layer) properties and 2) micromotor stopped flow in just 2 min by exploiting the magnetic properties (intermediate Ni layer). This strategy allowed fumonisin B1 determination with high sensitivity (limit of detection: 0.70 ng mL-1 ) and excellent accuracy (error: 0.05 % in certified reference material and quantitative recoveries of 104+/-4 % in beer) even in the presence of concurrent ochratoxin A (105-108+/-8 % in wines). These results confirm the developed approach as an innovative and reliable analytical tool for food-safety monitoring, and confirm the role of micromotors as a new paradigm in analytical chemistry. PMID- 29469988 TI - Dorsal root ganglia volume differentiates schwannomatosis and neurofibromatosis 2. AB - Schwannomatosis and neurofibromatosis type 2 are hereditary tumor syndromes, and peripheral neuropathy has been reported in both. We prospectively applied in vivo morphometric measurement of dorsal root ganglia volume in 16 schwannomatosis patients, 14 neurofibromatosis type 2 patients, and 26 healthy controls by magnetic resonance neurography. Compared to healthy controls, dorsal root ganglia hypertrophy was a consistent finding in neurofibromatosis type 2 (L3, + 267%; L4, + 235%; L5, + 241%; S1, + 300%; S2, + 242%; Bonferroni-adjusted p < 0.001) but not in schwannomatosis. Dorsal root ganglia may be a vulnerable site in origination of areflexia and sensory loss and a useful diagnostic marker in neurofibromatosis type 2. Ann Neurol 2018;83:854-857. PMID- 29469986 TI - Prevalence and duration of breast milk feeding in very preterm infants: A 3-year follow-up study and a systematic literature review. AB - BACKGROUND: The World Health Organization recommends exclusive breast milk feeding until 6 months and continuing up to 2 years of age; little is known about whether very preterm infants are fed in accordance with these recommendations. We aimed to describe the prevalence and duration of breast milk feeding in very preterm children and to systematically review internationally published data. METHODS: We evaluated breast milk feeding initiation and duration in very preterm children born in 2 Portuguese regions (2011-2012) enrolled in the EPICE cohort and followed-up to the age of 3 (n = 466). We searched PubMed(r) from inception to January 2017 to identify original studies reporting the prevalence and/or duration of breast milk feeding in very preterm children. RESULTS: 91.0% of children received some breast milk feeding and 65.3% were exclusively breast fed with a median duration of 2 months for exclusive and 3 months for any breast milk; only 9.9% received exclusive breast milk for at least 6 months, 10.2% received any breast milk for 12 months or more, and 2.0% for up to 24 months. The literature review identified few studies on feeding after hospital discharge (n = 9); these also reported a low prevalence of exclusive breast milk feeding at 6 months (1.0% to 27.0%) and of any breast milk at 12 months (8.0% to 12.0%). CONCLUSIONS: The duration of breast milk feeding among Portuguese very preterm infants was shorter than recommended. However, this appears to be common globally. Research is needed to inform strategies to promote continued breast milk feeding. PMID- 29469990 TI - Differential Metabolic Pathway Analysis of the Proteomes of Leishmania donovani and Leptomonas seymouri. AB - PURPOSE: Although in trypanosomatids, monoxeny (Leptomonas) is ancestral to dixeny (Leishmania), however clinical cases of visceral leishmanisis with Leptomonas co-infection are increasingly being reported from India. Using a proteogenomic approach, a detailed proteome analysis of these two kinetoplastid parasites viz., Leishmania and its sister Leptomonas, to catalog the key proteins associated with and therefore possibly responsible for phenotype changes in Leptomonas evolution and domestication as co-infection with Leishmania is carried out. EXPERIMENTAL DESIGN: LC-MS/MS is utilized for this proteomic purpose. One Leishmania donovani WHO reference strain and two Leptomonas seymouri isolates, which are originally isolated from clinical cases of kala azar patients with different inherent drug sensitivity viz., responsive and unresponsive, are used in this study. RESULTS: A network analysis, leveraging protein-protein interaction data helped to find the roles of the proteins in carbon metabolism and biosynthesis of secondary metabolites which is seen to be altered under stress conditions like drug resistance. CONCLUSIONS AND CLINICAL RELEVANCE: The information provided about the metabolic pathways modulated when contrasting these two phenotypes may lead to the development of new strategies to block parasite differentiation within the host and to also circumvent the problem of drug resistance. This proteomic study also offers new grounds for the investigation of novel hypothetical proteins potentially playing a role in evolutionary biology the knowledge of which is essential for treatment of patients co-infected with these two kinetoplastid parasites. PMID- 29469989 TI - Density and location of CD3+ and CD8+ tumor-infiltrating lymphocytes correlate with prognosis of oral squamous cell carcinoma. AB - BACKGROUND: Tumor-infiltrating lymphocytes (TILs) are regarded as adaptive immune response of the host to cancer cells and valuable prognostic factors. Here, we sought to characterize the densities and locations of CD3+ and CD8+ TILs in primary oral squamous cell carcinoma (OSCC) samples and assess their clinicopathological and prognostic significance. METHODS: A total number of 169 OSCC samples from 2 independent patient cohorts (Nanjing cohort, 93 cases; Wuxi cohort, 76 cases) were retrospectively collected. The numbers of CD3+ and CD8+ TILs at tumor center (CT) and invasive margin (IM) of OSCC were identified by immunohistochemistry and calculated. The optimal cutoff values for CD3+ and CD8+ TILs to stratify patients were determined by X-tile software in Nanjing cohort and further utilized in Wuxi cohort. The associations between CD3+ /CD8+ TILs and clinicopathological parameters or patient survival were assessed. The prognostic values of CD3+ / CD8+ TILs were evaluated by Cox regression analyses. RESULTS: CD3+ and CD8+ TILs were identified at both CT and IM and enriched at IM. High density of CD3+ TILs at IM (CD3 IM) was significantly associated with increased overall and disease-specific survival (P < .05). High density of CD8+ TILs at CT (CD8 CT) was significantly associated with increased overall but not disease specific survival. Moreover, CD3 IM and CD8 CT were identified as independent prognostic factors for patient survival. CONCLUSIONS: Our findings provide further evidence to support the prognostic values of CD3+ and CD8+ TILs for OSCC, suggesting that TIL subsets might be viable biomarkers and therapeutic targets with translational significance. PMID- 29469991 TI - Gene Expression on DNA Biochips Patterned with Strand-Displacement Lithography. AB - Lithographic patterning of DNA molecules enables spatial organization of cell free genetic circuits under well-controlled experimental conditions. Here, we present a biocompatible, DNA-based resist termed "Bephore", which is based on commercially available components and can be patterned by both photo- and electron-beam lithography. The patterning mechanism is based on cleavage of a chemically modified DNA hairpin by ultraviolet light or electrons, and a subsequent strand-displacement reaction. All steps are performed in aqueous solution and do not require chemical development of the resist, which makes the lithographic process robust and biocompatible. Bephore is well suited for multistep lithographic processes, enabling the immobilization of different types of DNA molecules with micrometer precision. As an application, we demonstrate compartmentalized, on-chip gene expression from three sequentially immobilized DNA templates, leading to three spatially resolved protein-expression gradients. PMID- 29469992 TI - Reproductive outcome of patients undergoing in vitro fertilisation treatment and diagnosed with bacterial vaginosis or abnormal vaginal microbiota: a systematic PRISMA review and meta-analysis. AB - BACKGROUND: Despite recent efforts, the risks associated with bacterial vaginosis (BV) or abnormal vaginal microbiota in IVF patients are not well-established. OBJECTIVES: We aimed to evaluate the risks associated with BV in IVF patients using meta-analysis. SEARCH STRATEGY: Following preliminary searches to find relevant keywords and MeSH terms, a systematic search was performed in PubMed (MEDLINE) in September 2017. SELECTION CRITERIA: The population was infertile women attending IVF treatment. The exposure was BV or abnormal vaginal microbiota. Outcomes included live birth rate, early spontaneous abortion rate and clinical pregnancy rate. DATA COLLECTION AND ANALYSIS: Data were collected for each study and for each outcome using a summary of findings table. If appropriate, data were quantitatively assessed using meta-analysis, sensitivity analysis, funnel plots and GRADE evidence assessment were performed for the above mentioned outcomes. MAIN RESULTS: A total of 12 studies were eligible, comprising a total of 2980 patients. The prevalence of BV was 16% (95% CI 15-18%) in the general study population and tubal factor infertility was highly prevalent in patients diagnosed with BV compared with normal vaginal microbiota patients (P = 0.001). Despite a significant association with early spontaneous abortion [relative risk (RR) 1.68, 95% CI 1.24-2.27], BV did not significantly impact the live birth rate (RR 1.47, 95% CI 0.96-1.57) or the clinical pregnancy rate (RR 0.93, 95% CI 0.75-1.15). CONCLUSIONS: BV is associated with tubal factor infertility and early spontaneous abortion. However, the quality of evidence was very low and the equivocal results justify the need for further research. TWEETABLE ABSTRACT: Abnormal vaginal microbiota is associated with early spontaneous abortion in IVF patients. PMID- 29469993 TI - Asthma among adult patients presenting with dyspnea to the emergency department: An observational study. AB - INTRODUCTION: Shortness of breath is a common presenting symptom to the emergency department (ED) that can arise from a myriad of possible diagnoses. Asthma is one of the major causes. OBJECTIVE: The aim of this study was to describe the demographic features, clinical characteristics, management and outcomes of adults with an ED diagnosis of asthma who presented to an ED in the Asia Pacific region with a principal symptom of dyspnea. METHODS: Planned sub-study of patients with an ED diagnosis of asthma identified in the Asia, Australia and New Zealand Dyspnoea in Emergency Departments (AANZDEM) study. AANZDEM was a prospective cohort study conducted in 46 EDs in Australia, New Zealand, Singapore, Hong Kong and Malaysia over three 72 hour periods in May, August and October 2014. Primary outcomes were patient epidemiology, clinical features, treatment and outcomes (hospital length of stay (LOS) and mortality). RESULTS: Of the 3044 patients with dyspnea, 387 (12.7%) patients had an ED diagnosis of asthma. The median age was 45 years, 60.1% were female, 16.1% were active or recent smokers and 30.4% arrived by ambulance. Inhaled bronchodilator therapy was initiated in 88.1% of patients, and 66.9% received both inhaled bronchodilators and systemic corticosteroids. After treatment in the ED, 65.4% were discharged. No death was reported. CONCLUSION: Asthma is common among patients presenting with a principal symptom of dyspnea in the ED of the Asia Pacific region. There was a suboptimal adherence to international guidelines on investigations and treatments of acute asthma exacerbations presenting an opportunity to improve the efficiency of care.

PMID- 29469995 TI - Hypobaric live high-train low does not improve aerobic performance more than live low-train low in cross-country skiers. AB - Live high-train low (LHTL) using hypobaric hypoxia was previously found to improve sea-level endurance performance in well-trained individuals; however, confirmatory controlled data in athletes are lacking. Here, we test the hypothesis that natural-altitude LHTL improves aerobic performance in cross country skiers, in conjunction with expansion of total hemoglobin mass (Hbmass , carbon monoxide rebreathing technique) promoted by accelerated erythropoiesis. Following duplicate baseline measurements at sea level over the course of 2 weeks, nineteen Norwegian cross-country skiers (three women, sixteen men, age 20 +/- 2 year, maximal oxygen uptake (VO2 max) 69 +/- 5 mL/min/kg) were assigned to 26 consecutive nights spent at either low (1035 m, control, n = 8) or moderate altitude (2207 m, daily exposure 16.7 +/- 0.5 hours, LHTL, n = 11). All athletes trained together daily at a common location ranging from 550 to 1500 m (21.2% of training time at 550 m, 44.2% at 550-800 m, 16.6% at 800-1100 m, 18.0% at 1100 1500 m). Three test sessions at sea level were performed over the first 3 weeks after intervention. Despite the demonstration of nocturnal hypoxemia at moderate altitude (pulse oximetry), LHTL had no specific effect on serum erythropoietin, reticulocytes, Hbmass , VO2 max, or 3000-m running performance. Also, LHTL had no specific effect on (a) running economy (VO2 assessed during steady-state submaximal exercise), (b) respiratory capacities or efficiency of the skeletal muscle (biopsy), and (c) diffusing capacity of the lung. This study, showing similar physiological responses and performance improvements in the two groups following intervention, suggests that in young cross-country skiers, improvements in sea-level aerobic performance associated with LHTL may not be due to moderate altitude acclimatization.

AB - Peri-implantitis remains one of the most challenging complications that could threaten the long-term survival of implants. The aim of this survey is to explore the experiences, attitudes and challenges that face clinicians in the management of peri-implantitis. A validated online questionnaire was emailed to implant clinicians in the United Kingdom. 72 clinicians responded to the questionnaire, all of whom face many challenges during the treatment of peri-implantitis, with 79% finding difficulties due to lack of treatment consensus and 78% finding treatment outcomes unpredictable. This survey highlights the marked differences in opinion and attitudes of clinicians in the management of peri-implantitis. PMID- 29469997 TI - The Influence of Nitrile Gloves on the Setting Behavior of Polyvinyl Siloxane Putty Impression Materials. AB - OBJECTIVE: The purpose of this study was to assess the gelation and polymerization time of three polyvinyl siloxane (PVS) putty materials and to determine if those times were affected by nitrile gloves under different conditions. MATERIALS AND METHODS: Ten specimens (n=10) were obtained for each PVS putty material (Express STD, 3M ESPE; Extrude Xtra, Kerr and Exafast, GC) and tested under different conditions (gloves washed, gloves unwashed and hands contaminated). The gelation and polymerization time were measured using an oscillating rheometer and recorded for 400 s at 37 degrees C to simulate the oral environment. RESULTS: The mean gelation time of hand contaminated specimens was 157.50 minutes and was significantly slower than that by using nitrile washed gloves (mean=117.94, p=.004) and by using unwashed gloves (mean=99.46, p?0.001). Unwashed gloves had significantly quicker gelation times compared to washed gloves (p=.046). The gelation time was significantly delayed with Exafast compared to Extrude Xtra and Express STD across all the different types of glove conditions (p?0.043). No significant differences were observed between polymerization time with Exafast and Extrude Xtra Putty. CONCLUSIONS: Extrude Xtra putty material had significantly better performance than GC Exafast and Express. Hand contaminated specimens were affected by the gelation/polymerization time. PMID- 29469998 TI - The Effect of Complete Denture Occlusion on Function and Patient Quality of Life: Systematic Review. AB - Edentulism presents an ongoing challenge for prosthodontic dentistry. Many aspects of complete denture construction lack contemporary evidence. One such aspect is denture occlusion. Balanced occlusion (BO) has become the prevailing occlusal scheme. It has been suggested that canine guidance (CG) is unsuitable for complete denture occlusion due to an increased risk for tipping of the prostheses. However it may be indicated in patients with minimal alveolus resorption. There has been limited evidence suggesting the superiority of either occlusal scheme over another. This article investigates the available literature assessing complete denture occlusion by means of clinical trials or reviews of evidence. We utilised PRISMA guidelines to investigate the effect of complete denture occlusal scheme (balance occlusion vs. canine guidance) on functional or quality of life. Seven studies were included for review. All studies were poor to moderate quality with the majority lacking randomisation, blinding and demographic data from the study sample. The available evidence suggests that the differences between occlusal schemes may be small, challenging the notion that BO may be the optimal occlusal scheme. There is a need for high-quality clinical research, investigating both chewing ability and quality of life in complete denture wearers in the long-term. PMID- 29469999 TI - A Systematic Review and Meta-Analysis of Baseline Ohip-Edent Scores. AB - BACKGROUND: OHIP-EDENT is widely used in the literature to assess Oral-Health Related-Quality-of-Life (OHRQoL) for edentulous patients. However the normal variance and mean of the baseline OHIP scores has not been reported. It would facilitate critical appraisal of studies if we had knowledge of the normal variation and mean of baseline OHIP-EDENT scores. An established figure for baseline OHIP-EDENT, obtained from a meta-analysis, would simplify comparisons of studies and quantify variations in initial OHRQoL of the trial participants. OBJECTIVES: The aim of this study is to quantify a normal baseline value for pre operative OHIP-EDENT scores by a systematic review and meta-analysis of the available literature. METHODS: A systematic literature review was carried. 83 papers were identified that included OHIP-EDENT values. After screening and eligibility assessment, 7 papers were selected and included in the meta-analysis. RESULTS: A meta-analysis for the 7 papers by a random-effect model yielded a mean baseline OHIP-EDENT score of 28.63 with a 95% Confidence intervals from 21.93 to 35.34. CONCLUSION: A pre-operative baseline OHIP-EDENT has been established by meta-analysis of published papers. This will facilitate the comparison of the initial OHRQoL of one study population to that found elsewhere in the published literature. PMID- 29470000 TI - Burnout or Joy?

AB - Pain is a major problem for individuals undergoing hemodialysis and can lead to decreased quality of life when ineffectively managed. Pain is often reported as burdensome; thus, nurses must learn effective, nonpharmacological adjuncts to help care for symptomatic patients. The purpose of this review was to identify non-pharmacologic complementary therapies and evaluate their effectiveness in minimizing pain among individuals undergoing hemodialysis. Multiple complementary interventions were identified, and several reduced pain, but evidence is qualified by limitations in study methods. Complementary therapies have the potential to reduce pain among individuals undergoing hemodialysis; however, more research is needed. PMID- 29470003 TI - Comfort and Fluid Retention in Adult Patients Receiving Hemodialysis. AB - Successful hemodialysis treatments for patients with renal failure depend on patient adherence to prescribed treatment regimens. Lack of adherence may contribute to patient discomfort between hemodialysis treatments. This article reports a descriptive, correlational feasibility study that utilized Kolcaba's Comfort Theory as a framework. The purpose of the study was to determine a potential relationship between comfort and fluid retention (a proxy for adherence) in adults with end stage renal disease receiving hemodialysis. A convenience sample of 51 patients receiving hemodialysis was studied. Comparisons of patient weight gain between hemodialysis treatment sessions measured fluid retention by proxy. Results indicated no significant relationship between the variables of comfort and adherence to fluid restrictions. However, this finding has potential to support clinical practice to minimize weight gain to sustain comfort. Awareness of comfort as a consideration for adherence to prescribed treatment regimens may help nurses coach individuals to improve treatment adherence. PMID- 29470004 TI - Accuracy and Utility of Estimating Lean Body Mass and Nutritional Status in Patients with Chronic Kidney Disease on Long-Term Hemodialysis Using Anthropometric Skinfold Thickness Measurements. AB - Malnutrition is common in patients on hemodialysis (prevalence of 30% to 50%) and is associated with higher mortality. Lean body mass (LBM) assessment is an accurate way of assessing nutritional status. The dual-energy X-ray absorptiometry (DEXA) scan is a reliable method in assessing body compositions and LBM; however, it is expensive and largely inaccessible. Anthropometric skinfold thickness measurement (ASFM) is useful in assessing LBM. It is cheaper and accessible, but underutilized clinically. The subjective global score (SGA) is a well-established method of assessing nutritional status. All three methods of assessing nutritional status were compared. In this pilot observational study, there was a significant correlation between LBM% estimated by DEXA and ASFM (mean difference -1.46% [95% CI -4.09 to 1.18]; LOA -14.0 to 11.1). Nutritional status by SGA could only detect those severely malnourished when using LBM% by ASFM as comparison. Our study demonstrated that ASFM is a useful method of assessing LBM and nutritional status, which can be easily utilized clinically. PMID- 29470005 TI - Factors Influencing the Introduction of a Process of Advance Care Planning in Outpatient Hemodialysis Facilities. AB - Individuals with kidney failure on outpatient hemodialysis therapy may experience many biopsycho social complications and existential concerns. Consequently, there is a need to implement a process of advance care planning to effectively meet the extensive needs of these individuals. However, this article suggests there are various barriers in some outpatient hemodialysis facilities that may hinder the introduction of advance care planning. This article provides a critical discussion of some of these elements, including increased time pressure, nurse patient communication, and the nurse-patient relationship. The article also makes recommendations that would facilitate the implementation of a process of advance care planning in outpatient hemodialysis facilities. PMID- 29470006 TI - Oxygen Saturation and Heart Rate Variations as Predictors of Intradialytic Hypotension. AB - AIntradialytic hypotension (IDH) occurring during hemodialysis (HD) may cause severe complications and can be life-threatening. IDH is a common symptom in patients with end stage renal disease undergoing HD. Currently, no effective predictive models for IDH exist. This study analyzed data on variations in oxygen saturation (SaO2) and heart rate (HR) in 68 patients during their HD sessions by using sequence alignment and Boolean algebra. Three classifiers derived from SaO2 and HR variation data were developed as predictors for predetermining IDH occurrence within 30 minutes. The accuracy of these classifiers in predicting IDH occurrence was approximately 80%. SaO2 and HR variations can potentially be used as predictors for developing an alarm system for detecting IDH occurrence.

AB - When the Red Cross opened its new convalescent home at Russell Lea in Sydney in 1919, it contained a coloured room designed for treating 'nerve cases'. This room was painted by Roy de Maistre, a young artist, and was modelled on the Kemp Prossor colour scheme trialled at the McCaul Convalescent Hospital in London for the treatment of shell shock. Dubbed the 'colour cure' by the popular press, this unconventional treatment was ignored by the Australian medical profession. The story of de Maistre's colour experiment is not widely known outside the specialist field of Australian art history. Focusing on the colour room as a point of convergence between art and medicine in the context of the First World War, this article investigates Red Cross activities and the care of soldiers suffering from nervous conditions. PMID- 29470015 TI - Introduction. Towards a Contemporary Historiography of Amateurs in Science (18th 20th Century). AB - The last few decades have seen considerable growth in the role played by amateurs in the sciences. With the development of new techniques for collecting information, new virtual networks and the emergence of new problematics calling for the participation of citizens, this role has also become more visible, while the modern boundary between professionalism and amateurism, first erected in the 19th century, has been shaken. These contemporary developments have changed our perspective on amateurs in science and brought forth questions and analyses that sometimes coincide with recent inflections in the history of science.Thus it is now possible to take a new approach to the historical study of amateurs in contemporary science. This introduction hopes to demonstrate this, while the essays brought together in this volume, some of which explore extreme cases, reveal the very relative nature of the definition of the "amateur" category and how complex and fertile its implementation has been in the history of science. PMID- 29470016 TI - [Neither Pedants nor Amateurs? Psychological Journals in Germany in the last three Decades of the 18th Century]. AB - Neither pedants nor amateurs? Psychological journals in Germany in the last three decades of the 18th century The Magazin zur Erfahrungsseelenkunde introduced a new tone in the evolving field of psychology. For the first time, attention was paid not to the abstract relationships between body and soul, but to suffering individuals from the "common folk". The collection and systematic publication ofaccounts of readers should eventually allow the formulation of an empirical "science of the soul". The readers would eventually send accounts of personal and experienced "cases". By 1800, this conception of the science of psychology was called into question by educated philosophers who, in journals opened only to specialists, endeavored to develop a more professional psychology. They nevertheless failed in formulating general criteria of scientificity. The main argument of this article is that the distinction between amateurs and scientists was not an outcome of the inner evolution of the field of psychology, but that it developed through practices of communication in which periodicals play a major role.

To become a self-sufficient scientific discipline, studies of birds had to distinguish themselves from luxury, trade and poetry. Scholars had to invent new ways of writing, different from the beautiful and ornamented books on birds, even if these books were often published by other scholars who had been expelled from academic institutions and therefore considered as "amateurs". The same scholars needed the help of "amateurs" in order to observe and explain bird migration. First ornithological discourses in Europe and the United States illustrate the relationships between scholars, authors and "amateurs" and show how these words can be used in different meanings.

AB - This article traces the unusual astronomical career of Jean Chacornac (1823-1873) during the French Second Empire. This clerk in a bazaar in Marseille became in just a few years astronomer at the Paris imperial observatory, and was then brutally expelled from this prestigious institution. The "Chacornac affair", largely forgotten, was an asymmetric struggle between a self-taught astronomer and the most famous professional French astronomer of the time, Urbain Le Verrier. Through the study of this case, we want to shed a light on people and practices kept on the margins of science by the process of professionalization of astronomy. Although he was excluded from the institution, Chacornac tried to continue to be an astronomer, independently, "from below".

On the one hand, thenetwork of the French Entomological Society, and on the other, a chair at the Museum national d'histoire naturelle. To illustrate this duality betweenacademic entomology and a more domestic entomology, we present a study based on two men: Charles Janet, a little-known province engineer who could be seen as a mere amateur among the professionals, Eugene-Louis Bouvier who was a scholar at the Museum national d'histoire naturelle and the Academy of Sciences. The biographical approach developed here will allow us to meet close associates of these two men. Considering their own perceptions we will see how these actors situated themselves within their discipline. This approach will allow us to give a broader picture of French entomologists around 1900: their number, their institutions, their relationships and their means of communication. This text shows that the amateur/professional dichotomy is an unsuitable tool to describe entomology at that time. PMID- 29470020 TI - [Marcel Sembat's Psychology: the Hobby of a Politician? AB - The socialist politician Marcel Sembat's unpublished manuscripts revealthe unexpected figure of a diarist with a passion for his own intimate, bodily,sexual and affective economy, and of an autodidact and sometimes polemicalreader of psychology (for instance Pierre Janet's). Sembat was recognizednonetheless as a potentially publishable author by Georges Dumas, the editorof the Journal de psychologie normale et pathologique, who asked him tocontribute an article - which was never published - on dreaming. Sembatwas also particularly receptive to Freud's early conceptions of sexuality. WasMarcel Sembat an amateur, like the painter Ingres playing the violin?

AB - At the beginning of the XXth century, Wegener proposed a theory - that of the roaming drift of the continents - unifying the rival theories of the Europeans and the Americans. As the work of a non-specialist who didn't trouble himself with specific details, it raised numerous criticisms from specialists in various disciplines though others welcomed and supported it. Some even understood that despite its flaws, it started a new research program. Paradoxically, as regards its simplicity, nonspecialists - engineers, popularizers, secondary school teachers and even believers in para-sciences - gave it a favorable reception. Being amateurs, they continued to endorse it when specialists abandoned it. PMID- 29470022 TI - [Anne Berman (1889-1979): a "Mere Secretary" in the French Psychoanalytic Movement?]. AB - This article is focused on the figure of personal secretary in the history of science with the example of Anne Berman (1889-1979) who was, between1933 and 1962, the secretary for the psychoanalyst Marie Bonaparte (1882-1962). Berman was not a psychoanalyst and psychoanalytic historiography considers her as a minor figure. However, her career as a personal secretary and her role in the French psychoanalytic movement should be considered in conjunction with her involvement with the feminist movement. This pharmacist by training has indeed played a prominent role within the Soroptimist, which was a movement that championed the professional interest of women and prides female excellence. In the case of Berman, the status of personal secretary did not enable her to gain lasting recognition by psychoanalysts, but only a weak and fragile legitimacy.

AB - This article is concerned with exploring the historical development of Reinforce, the oldest self-advocacy organisation for people with intellectual disability in Victoria. In particular, it considers how governmental indifference, as well as ad hoc funding and support, has hindered the growth of the organisation and, more generally, the growth of the self-advocacy movement in Victoria. By obtaining a deeper understanding of the input from the policy makers, professionals, and supporters working in the field of intellectual disability, we can begin to comprehend some of the reasons for the comparatively slow development of self advocacy in this country.

AB - The outbreak of the First World War in August 1914 was met with much jingoistic enthusiasm by the Australian population. Men volunteered in their hundreds for service for God, King, and Country; to defend the Empire; for adventure; and to see the world. Women on the homefront formed up Red Cross branches across the country in small country towns and city suburbs to serve 'their boys'. Unfortunately for the men who enlisted their desire to serve the Empire was not met with a similar level of organisational efficiency by authorities in Australia. The military were completely overwhelmed by the progress of the war, especially the level of casualties that resulted from the Gallipoli campaign.

AB - The close connections between colonialism and tropical medicine have been widely discussed by historians over the last fifty years. However, few authors consider the relationship between tropical medicine and European and North American imperialism in the immediate post-World War II period. This article examines the Fourth International Congresses on Tropical Medicine and Malaria, held jointly in Washington in 1948. Using the research presented during the conference, it questions to what degree the specialisation had changed in the postwar period. It argues that although some changes are discernable, imperial traditions and relationships remained firmly embedded within the tropical medicine of the congress.

AB - Since 1975, Cambodia has transitioned through three distinct political periods of totalitarian, centralist, and neo liberal rule. In order to understand the challenges these political reforms present for health systems and policies, this case study charts events in health policy and political history in Cambodia between 1975 and 2014. Findings illustrate the interconnections of health and history, the balancing of tradition and modernity in health management and medical practice, and the shift in policy positions in response to political and economic reform. This historical view has the potential to enhance the capability of policy makers to not only understand the origins of current health policy positions, but also to anticipate and respond more flexibly to emerging health policy challenges. PMID- 29470036 TI - The Hangover: The Early and Lasting Effects of the Controversial Incorporation of X-Ray Technology into Chiropractic. AB - Chiropractic first adopted the X-ray in 1910 for the purpose of demonstrating tiny misalignments of spinal bones, theorised to cause all disease, which they called chiropractic subluxations. This paper explores the apparent contradiction and resultant controversy of a system of natural healing adopting a medical technology. It centres on the actions of B.J. Palmer, the first chiropractor to use X-rays. It also clarifies details of Palmer's decision to incorporate the technology and interprets the change in the sociological context of boundary work. The continuing use of the subluxation paradigm for radiography by chiropractors has had a lingering effect on the profession, a metaphorical hangover of vitalism that is not consistent with modern healthcare practice. As a result of this conflict, arguments within the profession on the use of X-rays contribute to the continuing schism between evidence-based and subluxation-based chiropractors.

PMID- 29470039 TI - Unfathomable Journey: The Context of Dr. Otto Walter's Departure from Australia. AB - Fifty years ago, erstwhile eminent Jewish physician Dr Otto Walter abandoned life in Australia to return to Austria, leaving his crestfallen young grandson, Garry, to wonder why he had gone. In this paper, the author explores the possible reasons for his grandfather's departure, weaving in aspects of Otto's extraordinary life, including the flight from Vienna after Kristallnacht (the German Reich's coordinated night of attacks on Jewish property), and the struggles to stay one step ahead of the Nazis in Europe. Otto was to settle in the British Mandate for Palestine (later Israel), before coming to Australia in 1949 on the Cyrenia-serving as ship's doctor for Jewish refugees. In Australia, the consummate medical skills that had proven life-saving for Otto's family, were not formally recognised, marking the end of a distinguished career. PMID- 29470040 TI - Courage under Adversity: Luba Bielicka-Blum (1906-1973) and the Nursing School of the Warsaw Ghetto. AB - The Warsaw Ghetto was a place where Jews were kept until deportation to Nazi death camps. It contained a nursing school, run by Luba Bielicka-Blum. We explore the contribution of Luba Bielicka-Blum to nursing and specifically, the nursing school of the Warsaw Ghetto by using primary sources of Bielicka-Blum's daughter's archive held by Yad Veshem, supported by secondary sources. We conclude that, despite extreme hardship and abject horror, the nursing school in the Warsaw Ghetto continued to provide the highest level of nursing education possible. The relatively unknown story of Luba Bielicka-Blum and her determination to continue the education of nurses in the Warsaw Ghetto demonstrates the courage of a nursing leader during dreadful times. PMID- 29470041 TI - Doctors and the Armenian and Bosnian Genocides. AB - The extensive degree of mass murder that occurred throughout the twentieth century saw the rate of non-combatant (civilian) deaths rise by over seventy-five percent in the space of seventy years, amounting to a death toll exceeding 170 million. Where genocides are concerned, the central role of doctors is undeniable. Their participation arose from the preoccupation with eugenics for improving the health of the nation. From here, their belief in nationalism overrode the sacred duty to save lives. These doctors descended into moral anarchy, breaching an ethical code of two millennia. This paper examines the role of doctors in the Armenian genocide and that of psychiatrists (notably Radovan Karadzic), in the Bosnian genocide. That medicine contains the seeds of its own destruction is confirmed by the recurrent involvement of doctors in genocide. PMID- 29470042 TI - Fabrication of Charge-Conversion Nanoparticles for Cancer Imaging by Flash Nanoprecipitation. AB - Traditional charge-conversion nanoparticles (NPs) need the breakage of acid labile groups on the surface, which impedes the rapid response to the acidic microenvironment. Here, we developed novel rodlike charge-conversion NPs with amphiphilic dextran- b-poly(lactic- co-glycolic acid), poly(2-(dimethylamino) ethylmethylacrylate)- b-poly(epsilon-caprolactone), and an aggregation-induced emission-active probe through flash nanoprecipitation (FNP). These NPs exhibit reversible negative-to-positive charge transition at a slightly acidic pH relying on the rapid protonation/deprotonation of polymers. The size and the critical charge-conversion pH can be further tuned by varying the flow rate and polymer ratio. Consequently, the charge conversion endows NPs with resistance to protein adsorption at physiological pH and enhanced internalization to cancer cells under acidic conditions. Ex vivo imaging on harvest organs shows that charge-conversion NPs were predominantly distributed in tumors after intravenous administration to mice due to the robust response of NPs to the acidic microenvironment in tumor tissue, whereas control NPs or free probes were broadly accumulated in tumor, liver, kidney, and lung. These results suggest the great potential of the current FNP strategy in the facile and generic fabrication of charge-conversion NPs for tumor-targeting delivery of drugs or fluorescent probes.

AB - The platinum nanoparticles (Pt NPs) hybrided with nanostructured carbon materials with high stability are important for catalyzing hydrogenation reaction. Here we reported the fabrication of ultrastable Pt NPs anchored on graphdiyne, in which the strong interactions induced by the porous graphdiyne can prevent the thermal migration of Pt nanoparticles on the graphdiyne surface, exploiting the strong charge transfer interactions from Pt NPs to GDY substrate to tune the electron density of Pt NPs. Pt NPs catalyst with size of 2-3 nm showed high performance on hydrogenation of aldehydes and ketones to the corresponding alcohols compared with commercial Pt-C. Our results indicated that graphdiyne is a promising substrate for constructing metal nanoparticle-based heterogeneous catalysts, especially for those requiring strong interactions between metal nanoparticles and reactants. PMID- 29470044 TI - Polycrystalline Diamond Coating of Additively Manufactured Titanium for Biomedical Applications. AB - Additive manufacturing using selective laser melted titanium (SLM-Ti) is used to create bespoke items across many diverse fields such as medicine, defense, and aerospace. Despite great progress in orthopedic implant applications, such as for "just in time" implants, significant challenges remain with regards to material osseointegration and the susceptibility to bacterial colonization on the implant. Here, we show that polycrystalline diamond coatings on these titanium samples can enhance biological scaffold interaction improving medical implant applicability. The highly conformable coating exhibited excellent bonding to the substrate. Relative to uncoated SLM-Ti, the diamond coated samples showed enhanced mammalian cell growth, enriched apatite deposition, and reduced microbial S. aureus activity. These results open new opportunities for novel coatings on SLM-Ti devices in general and especially show promise for improved biomedical implants. PMID- 29470045 TI - Surface-Enhanced Raman Scattering Detection of Pesticide Residues Using Transparent Adhesive Tapes and Coated Silver Nanorods. AB - The efficient extraction of analytes from complex and severe environments is significant for promoting the surface-enhanced Raman scattering (SERS) technique to actual applications. In this paper, a proof-of-concept strategy is proposed for the rapid detection of pesticide residues by utilizing the flexible, transparent, and adhesive properties of commercial tapes and SERS performance of Al2O3-coated silver nanorod (AgNR@Al2O3) arrays. The function of tapes is to rapidly transfer the analytes from the actual surface to the SERS substrate. The novel "tape-wrapped SERS (T-SERS)" approach was constructed by a simple "paste, peel off, and paste again" procedure. The easily obtained but clearly distinguished SERS signals allow us to quickly determine the constituents of complex surfaces, such as tetramethylthiuram disulfide and thiabendazole pesticides from fruits and vegetables, which may be practically applied to food safety, environmental monitoring, and industrial production process controlling.

AB - To explore a new series of cathode materials with high electrochemical performance, the spinel-layered (1 - x)[LiCrMnO4]. x[Li2MnO3.LiCrO2] ( x = 0, 0.25, 0.5, 0.75, and 1) composites are synthesized with the sol-gel method. X-ray diffraction, high-resolution transmission electron microscopy, selected area electron diffraction, and Raman spectra reveal that the structure of the (1 - x)[LiCrMnO4]. x[Li2MnO3.LiCrO2] cathode materials evolves from spinel to hybrid spinel-layered and layered structures with the increase of the Li concentration. Test results reveal that the structure and electrochemical performance of (1 - x)[LiCrMnO4]. x[Li2MnO3.LiCrO2] ( x = 0.25, 0.5 and 0.75) composites have the characteristics of both spinel ( x = 0) and Li-rich layered phases ( x = 1). In particular, x = 0.5 and 0.75 electrodes exhibit relatively high capacity retention and rate capability, which is mainly ascribed to the synergistic effect of the spinel and Li-rich layered phases, the 3D Li-ion diffusion channels of the spinel phase, and the low charge-transfer resistance ( Rct) and Warburg diffusion impedance ( Wo). PMID- 29470047 TI - Heterostructured Nanorings of Fe-Fe3O4@C Hybrid with Enhanced Microwave Absorption Performance. AB - Microwave absorption is a critical challenge with progression in electronics, where fine structural designing of absorbent materials plays an effective role in optimizing their microwave absorption properties. Here, we have developed Fe3O4@C (FC) and Fe-Fe3O4@C (FFC) hybrid nanorings via a hydrothermal method coupled with a chemical catalytic vapor deposition technique. FC and FFC hybrid nanorings have fine carbon coating while their size can easily be tunable in a certain range from 80-130 to 90-140 nm. The optimized FC and FFC hybrid nanorings bear minimum reflection loss (RL) values of -39.1 dB at 15.9 GHz and -32.9 dB at 17.1 GHz, respectively, whereas FFC shows an effective absorption bandwidth (RL values < 10 dB) ranged from 5.2 to 18 GHz. Such an enhanced microwave absorption performance of hybrid nanorings is mainly due to the suitable impedance characteristics, multilevel interfaces, and polarization features in nanorings. This work provides an approach to design hybrid materials having a complex structure to enhance the microwave absorption properties. PMID- 29470048 TI - Designing Porphyrinic Covalent Organic Frameworks for the Photodynamic Inactivation of Bacteria. AB - Microbial colonization of biomedical devices is a recognized complication contributing to healthcare-associated infections. One of the possible approaches to prevent surfaces from the biofilm formation is antimicrobial photodynamic inactivation based on the cytotoxic effect of singlet oxygen, O2(1Deltag), a short-lived, highly oxidative species, produced by energy transfer between excited photosensitizers and molecular oxygen. We synthesized porphyrin-based covalent organic frameworks (COFs) by Schiff-base chemistry. These novel COFs have a three-dimensional, diamond-like structure. The detailed analysis of their photophysical and photochemical properties shows that the COFs effectively produce O2(1Deltag) under visible light irradiation, and especially three dimensional structures have strong antibacterial effects toward Pseudomonas aeruginosa and Enterococcus faecalis biofilms. The COFs exhibit high photostability and broad spectral efficiency. Hence, the porphyrinic COFs are suitable candidates for the design of antibacterial coating for indoor applications.

PMID- 29470049 TI - A Versatile Route toward the Electromagnetic Functionalization of Metal-Organic Framework-Derived Three-Dimensional Nanoporous Carbon Composites. AB - Designable electromagnetic parameters accompanied by a low density of metal organic framework (MOF)-derived metal/carbon composites are essential prerequisites for excellent microwave-absorbing materials. However, the conventional route is confined to slight modification of the physicochemical properties of metal species and carbon, which also restricts the functionalization of MOF-derived materials. Here, a facile technique has been improved by making full use of highly porous structure to uniformly introduce metallic Co nanoparticles into carbon matrix derived from Cu3(btc)2. Through changing the starting amount of Co sources, the composition of the final products can be tuned, offering an effective route to control electromagnetic properties. Multiple attenuation mechanisms are employed to realize excellent reflection loss performance, which can be clarified by modified equivalent circuit mode. Effective frequency bandwidth ( fe) over the whole X band can be obtained by optimizing interfacial polarization through changing interface area and electrical conductivity. Broad fe covering almost the whole Ku band from 12.3 to 18 GHz with a thin thickness of 1.85 mm can be gained through improving impedance matching and enhancing conduction loss. The present work not only sheds light on the easy fabrication of high-performance lightweight microwave-absorbing materials but also paves the way for extending functionalities of MOF-derived carbon composites.

AB - Coordination-driven assembly has been widely successful in the synthesis of metallocages and used for many applications, such as catalysis. However, studies on CO2 adsorption with metallocages have been rarely conducted, compared to other well-known cage-type materials, such as porous organic cages. In this study, a rational choice of ligand and metal led to the synthesis of a Zr6L3-type metallocage, exhibiting exceptional CO2 adsorption properties. CO2 adsorption experiments revealed that the metallocage shows highly selective adsorption of CO2 over N2 with high CO2 binding energy. Density functional theory calculations uncovered the origin of this exceptional affinity for CO2 over N2. PMID- 29470052 TI - Flexible Asymmetric Supercapacitor Based on Functionalized Reduced Graphene Oxide Aerogels with Wide Working Potential Window. AB - Flexible energy storage devices are in great demand since the advent of flexible electronics. Until now, flexible supercapacitors based on graphene analogues usually have had low operating potential windows. To this end, two dissimilar electrode materials with complementary potential ranges are employed to obtain an optimum cell voltage of 1.8 V. A low-temperature organic sol-gel method is used to prepare two different types of functionalized reduced graphene oxide aerogels (rGOA) where Ag nanorod functionalized rGOA acts as a negative electrode while polyaniline nanotube functionalized rGOA acts as a positive electrode. Both materials comprehensively exploit their unique properties to produce a device that has high energy and power densities. An assembled all-solid-state asymmetric supercapacitor gives a high energy density of 52.85 W h kg-1 and power density of 31.5 kW kg-1 with excellent cycling and temperature stability. The device also performs extraordinarily well under different bending conditions, suggesting its potential to meet the requirements for flexible electronics. PMID- 29470053 TI - Ag3PO4@UMOFNs Core-Shell Structure: Two-Dimensional MOFs Promoted Photoinduced Charge Separation and Photocatalysis. AB - Metal-organic frameworks (MOFs) are a new type of functional material that is self-assembled by metal ions and organic ligands. In this paper, a bimetal organic framework was synthesized and stripped into two-dimensional nanosheets structure via an ultrasonic method. We coated the UMOFNs (ultrathinning MOFs into two-dimensional nanosheets) on Ag3PO4 nanoparticles to obtain Ag3PO4@UMOFNs core shell photocatalysts. Under visible-light irradiation, the degradation of phenol was 100% within 16 min, and the degradation of biphenyl A was 98.9% within 20 min via Ag3PO4@UMOFNs (5 wt %). These values were 1.6- and 1.8-times higher than Ag3PO4, respectively. The activity of the Ag3PO4@UMOFNs increased due to the synergistic effects. The pi-pi bonds of the organic ligands and weak interactions between UMOFNs and Ag3PO4 collectively promote charge transfer. In addition, matching energy-level structures and a sufficiently large contact area accelerate the separation of the photogenerated charges and improve the activity. This remarkably improves the photocatalytic activity. PMID- 29470054 TI - In Situ Growth of Layered Bimetallic ZnCo Hydroxide Nanosheets for High Performance All-Solid-State Pseudocapacitor.

Herein, we report ZnCo1.5(OH)4.5Cl0.5.0.45H2O nanosheets (thickness ~30 nm) which crystallize in a layered structure and exhibit a high specific capacitance of 3946.5 F g-1 at 3 A g-1 for an electrochemical pseudocapacitor. ZnCo1.5(OH)4.5Cl0.5.0.45H2O was synthesized by a homogeneous precipitation method and spontaneously crystallized into 2D nanosheets in well-defined hexagonal morphology with crystal structure revealed by synchrotron X-ray powder diffraction data analysis. In situ growth of ZnCo1.5(OH)4.5Cl0.5.0.45H2O nanosheet arrays on conductive Ni foam substrate was successfully realized. Asymmetric supercapacitors based on ZnCo1.5(OH)4.5Cl0.5.0.45H2O nanosheets @Ni foam// PVA, KOH//reduced graphene oxide exhibits a high energy density of 114.8 Wh kg-1 at an average power density of 643.8 W kg-1, which surpasses most of the reported all-solid-state supercapacitors based on carbonaceous materials, transition metal oxides/hydroxides, and MXenes. Furthermore, a supercapacitor constructed from ZnCo1.5(OH)4.5Cl0.5.0.45H2O nanosheets@PET substrate shows excellent flexibility and mechanical stability. This study provides layered bimetallic hydroxide nanosheets as promising electroactive materials for flexible, solid-state energy storage devices, presenting the best reported performance to date. PMID- 29470056 TI - Dynamics and Removal Pathway of Edge Dislocations in Imperfectly Attached PbTe Nanocrystal Pairs: Toward Design Rules for Oriented Attachment. AB - Using in situ high-resolution TEM, we study the structure and dynamics of well defined edge dislocations in imperfectly attached PbTe nanocrystals. We identify that attachment of PbTe nanocrystals on both {100} and {110} facets gives rise to b = a/2?110? edge dislocations. Based on the Burgers vector of individual dislocations, we can identify the glide plane of the dislocations. We observe that defects in particles attached on {100} facets have glide planes that quickly intersect the surface, and HRTEM movies show that the defects follow the glide plane to the surface. For {110} attached particles, the glide plane is collinear with the attachment direction, which does not provide an easy path for the dislocation to reach the surface. Indeed, HRTEM movies of dislocations for {110} attached particles show that defect removal is much slower. Further, we observe conversion from pure edge dislocations in imperfectly attached particles to dislocations with mixed edge and screw character, which has important implications for crystal growth. Finally, we observe that dislocations initially closer to the surface have a higher speed of removal, consistent with the strong dislocation free surface attractive force. Our results provide important design rules for defect-free attachment of preformed nanocrystals into epitaxial assemblies. PMID- 29470057 TI - Mass Spectrometry-Based Immunoassay for the Quantification of Banned Ruminant Processed Animal Proteins in Vegetal Feeds. AB - The ban of processed animal proteins (PAPs) in feed for farmed animals introduced in 2001 was one of the main EU measures to control the bovine spongiform encephalopathy (BSE) crisis. Currently, microscopy and polymerase chain reaction (PCR) are the official methods for the detection of illegal PAPs in feed. However, the progressive release of the feed ban, recently with the legalization of nonruminant PAPs for the use in aquaculture, requires the development of alternative methods to determine the species origin and the source (legal or not). Additionally, discussions about the need for quantitative tests came up, particularly if the zero-tolerance-concept is replaced by introducing PAP thresholds. To address this issue, we developed and partially validated a multiplex mass spectrometry-based immunoassay to quantify ruminant specific peptides in vegetal cattle feed. The workflow comprises a new sample preparation procedure based on a tryptic digestion of PAPs in suspension, a subsequent immunoaffinity enrichment of the released peptides, and a LC-MS/MS-based analysis for peptide quantification using isotope labeled standard peptides. For the very first time, a mass spectrometry-based method is capable of detecting and quantifying illegal PAPs in animal feed over a concentration range of 4 orders of magnitude with a detection limit in the range of 0.1% to 1% (w/w).

PMID- 29470059 TI - Low-Pressure Nanofiltration Hollow Fiber Membranes for Effective Fractionation of Dyes and Inorganic Salts in Textile Wastewater. AB - In this work, novel loose nanofiltration (NF) hollow fiber membranes with ultrahigh water permeability and well-defined nanopore and surface charge characteristics were developed for effective fractionation of dyes and inorganic salts in textile wastewater treatment. The as-spun NF hollow fiber possesses a high pure water permeability (PWP) of 80 L.m-2.h-1.bar-1 with a small pore size of 1.0 nm in diameter and a MWCO of 1000 Da. The surface modification by means of hyperbranched polyethylenimine (PEI) further lowers the pore diameter to 0.85 nm and MWCO to 680 Da. The membrane surface also becomes more hydrophilic and positively charged after the PEI modification. Because of the synergistic effects from size exclusion and charge repulsion, the newly developed NF hollow fibers show high permeation fluxes of 7.0-71.2 L.m-2.h-1 and great rejections of 95.5 99.9% to various dyes at a low operating pressure of 1 bar. At the same time, they have ultralow rejections of less than 10% to inorganic salts (i.e., Na2SO4), suggesting that more than 90% of the salts would permeate through the fibers. In addition, the two hollow fibers exhibit outstanding performance stability, low fouling tendency, and great fouling reversibility. Their fluxes can be brought back to be more than 80% of the original values by a simple physical backwash. The newly developed loose NF hollow fiber membranes may have great potential for effective fractionation and treatment of textile wastewater.

AB - The physical factors governing the regioselectivity of the double functionalization of fullerenes have been explored by means of density functional theory calculations. To this end, the second Diels-Alder cycloaddition reactions involving 1,3-butadiene and the parent C60 fullerene as well as the ion encapsulated system Li+@C60 have been selected. In agreement with previous experimental findings on related processes, it is found that the cycloaddition reaction, involving either C60 or Li+@C60, occurs selectively at specific [6,6] bonds. The combination of the activation strain model of reactivity and the energy decomposition analysis methods has been applied to gain a quantitative understanding into the markedly different reactivity of the available [6,6]-bonds leading to the observed regioselectivity in the transformation. PMID- 29470061 TI - Solid-Phase Extraction Coupled to a Paper-Based Technique for Trace Copper Detection in Drinking Water. AB - Metal contamination of natural and drinking water systems poses hazards to public and environmental health. Quantifying metal concentrations in water typically requires sample collection in the field followed by expensive laboratory analysis that can take days to weeks to obtain results. The objective of this work was to develop a low-cost, field-deployable method to quantify trace levels of copper in drinking water by coupling solid-phase extraction/preconcentration with a microfluidic paper-based analytical device. This method has the advantages of being hand-powered (instrument-free) and using a simple "read by eye" quantification motif (based on color distance). Tap water samples collected across Fort Collins, CO, were tested with this method and validated against ICP MS. We demonstrate the ability to quantify the copper content of tap water within 30% of a reference technique at levels ranging from 20 to 500 000 ppb. The application of this technology, which should be sufficient as a rapid screening tool, can lead to faster, more cost-effective detection of soluble metals in water systems. PMID- 29470055 TI - Unique Molecular Regulation of Higher-Order Prefrontal Cortical Circuits: Insights into the Neurobiology of Schizophrenia. AB - Schizophrenia is associated with core deficits in cognitive abilities and impaired functioning of the newly evolved prefrontal association cortex (PFC). In particular, neuropathological studies of schizophrenia have found selective atrophy of the pyramidal cell microcircuits in deep layer III of the dorsolateral PFC (dlPFC) and compensatory weakening of related GABAergic interneurons. Studies in monkeys have shown that recurrent excitation in these layer III microcircuits generates the precisely patterned, persistent firing needed for working memory and abstract thought. Importantly, excitatory synapses on layer III spines are uniquely regulated at the molecular level in ways that may render them particularly vulnerable to genetic and/or environmental insults. Glutamate actions are remarkably dependent on cholinergic stimulation, and there are inherent mechanisms to rapidly weaken connectivity, e.g. during stress. In particular, feedforward cyclic adenosine monophosphate (cAMP)-calcium signaling rapidly weakens network connectivity and neuronal firing by opening nearby potassium channels. Many mechanisms that regulate this process are altered in schizophrenia and/or associated with genetic insults. Current data suggest that there are "dual hits" to layer III dlPFC circuits: initial insults to connectivity during the perinatal period due to genetic errors and/or inflammatory insults that predispose the cortex to atrophy, followed by a second wave of cortical loss during adolescence, e.g. driven by stress, at the descent into illness. The unique molecular regulation of layer III circuits may provide a nexus where inflammation disinhibits the neuronal response to stress. Understanding these mechanisms may help to illuminate dlPFC susceptibility in schizophrenia and provide insights for novel therapeutic targets.

AB - Oxygen evolution reaction (OER), as the critical step in splitting water, is a thermodynamically "up-hill" process and requires highly efficient catalysts to run. Arrhenius' law suggests that the higher temperature, the faster the reaction rate, so that a larger OER current density can be achieved at a lower eta. Herein, we report an abnormal temperature effect on the performance of Co-based catalysts, e.g., Co3O4, Li2CoSiO4, and Fe-doped Co(OH) x, in OER in alkaline electrolytes. The OER performance reached a maximum when the temperature increased to 65 degrees C, and the OER performance declined when the temperature became higher. The mechanism was investigated by using Co3O4 as a model sample, and we propose that at an optimal temperature (around 55-65 degrees C) the main rate-determining step changes from OH- adsorption dominant to a mixed mode and both the adsorption and the cleavage of the OH group can be rate-determining, which leads to the fastest kinetics. PMID- 29470063 TI - Prediction of 19F NMR Chemical Shifts for Fluorinated Aromatic Compounds. AB - Scaling factors are reported for use in predicting 19F NMR chemical shifts for fluorinated (hetero)aromatic compounds with relatively low levels of theory. Our recommended scaling factors were developed using a curated data set of 52 compounds, with 100 individual 19F shifts spanning a range of 153 ppm. With a maximum deviation of 6.5 ppm between experimental and computed shifts, or 4% of the range tested, these scaling factors allow for the assignment of chemical shifts to specific fluorines in multifluorinated aromatics. The utility of this approach is highlighted by several structural reassignments.

AB - As a modulatable class of porous crystalline materials, metal-organic frameworks (MOFs) have gained intensive research attention in the domain of gas storage and separation. In this study, we report on the synthesis and gas adsorption properties of two robust MOFs with the general formula [Co3(MU3-OH)(cpt)3Co3(MU3 OH)(L)3(H2O)9](NO3)4(guests) n [L = 3-amino-1,2,4-triazole (1) and 3,5-diamino 1,2,4-triazole (2); Hcpt = 4-(4-carboxyphenyl)-1,2,4-triazole], which show the same pacs topology. Both MOFs are isostructural to each other and show MIL-88 type frameworks whose pore spaces are partitioned by different functionlized trinuclear 1,2,4-triazolate-based clusters. The similar framework components with different amounts of functional groups make them an ideal platform to permit a systematic gas sorption/separation study to evaluate the effects of distinctive parameters on the C2H2 uptake and separation performance. Because of the presence of additional amido groups, the MOF 2 equipped with a datz-based cluster (Hdatz = 3,5-diamino-1,2,4-triazole) shows a much improved C2H2 uptake capacity and separation performance over that of the MOF 1 equipped with atz-based clusters (Hatz = 3-amino-1,2,4-triazole), although the surface area of the MOF 1 is almost twice than that of the MOF 2. Moreover, the high density of open metal sites, abundant free amido groups, and charged framework give the MOF 2 an excellent C2H2 separation performance, with ideal adsorbed solution theory selectivity values reaching up to 11.5 and 13 for C2H2/C2H4 (1:99) and C2H2/CO2 (50:50) at 298 K and 1 bar, showing potential for use in natural gas purification.

AB - Noninvasive methods to modulate G protein-coupled receptors (GPCRs) with temporal and spatial precision are in great demand. Photopharmacology uses photons to control in situ the biological properties of photoswitchable small-molecule ligands, which bodes well for chemical biological precision approaches. Integrating the light-switchable configurational properties of an azobenzene into the ligand core, we developed a bidirectional antagonist toolbox for an archetypical family A GPCR, the histamine H3 receptor (H3R). From 16 newly synthesized photoswitchable compounds, VUF14738 (28) and VUF14862 (33) were selected as they swiftly and reversibly photoisomerize and show over 10-fold increased or decreased H3R binding affinities, respectively, upon illumination at 360 nm. Both ligands combine long thermal half-lives with fast and high photochemical trans-/ cis conversion, allowing their use in real-time electrophysiology experiments with oocytes to confirm dynamic photomodulation of H3R activation in repeated second-scale cycles. VUF14738 and VUF14862 are robust and fatigue-resistant photoswitchable GPCR antagonists suitable for spatiotemporal studies of H3R signaling. PMID- 29470069 TI - Photochemistry of fac-[Re(CO)3(dcbH2)( trans-stpy)]+: New Insights on the Isomerization Mechanism of Coordinated Stilbene-like Ligands. AB - In this work, a novel complex fac-[Re(CO)3(dcbH2)( trans-stpy)]+, (dcbH2 = 4,4' dicarboxylic acid-2,2'-bipyridine; trans-stpy = trans-4-styrylpyridine) was synthesized and characterized toward its spectroscopic, photochemical, and photophysical properties. The experimental data provide new insights on the mechanism of photochemical trans-to- cis isomerization of the stilbene-like ligand coordinated to Re(I) polypyridyl complexes. The new complex exhibits an unusual and strong dependence of the isomerization quantum yield (Phit ->c) on the irradiation wavelength. Phit ->c was 0.81 +/- 0.08 for irradiation at 365 nm and continuously decreased as the irradiation wavelength is shifted to the visible. At 405 nm irradiation Phit ->c is almost 2 orders of magnitude lower (0.010 +/- 0.005) than that observed at 365 nm excitation. This behavior can be explained by the low-lying triplet metal-to-ligand charge-transfer excited state (3MLCT) that hinders the triplet photoreaction mechanism under visible light absorption. Under UV irradiation, direct population of styrylpyridine-centered excited state (1IL) leads to the occurrence of the photoisomerization via a singlet mechanism. Further experiments were performed with the complex immobilized on the surface of TiO2 and Al2O3 films. The nonoccurrence of isomerization at the oxide surfaces even under UV excitation evidences the role of energy gap between the 1IL/1MLCT states on the photochemical/photophysical processes. The results establish important relationships between the molecular structure and the photoelectrochemical behavior, which can further contribute to the development of solid-state molecular switches based on Re(I) polypyridyl complexes.

AB - EphA2 overexpression has been associated with metastasis in multiple cancer types, including melanomas and ovarian, prostate, lung, and breast cancers. We have recently proposed the development of peptide-drug conjugates (PDCs) using agonistic EphA2-targeting agents, such as the YSA peptide or its optimized version, 123B9. Although our studies indicated that YSA- and 123B9-drug conjugates can selectively deliver cytotoxic drugs to cancer cells in vivo, the relatively low cellular agonistic activities (i.e., the high micromolar concentrations required) of the agents toward the EphA2 receptor remained a limiting factor to the further development of these PDCs in the clinic. Here, we report that a dimeric version of 123B9 can induce receptor activation at nanomolar concentrations. Furthermore, we demonstrated that the conjugation of dimeric 123B9 with paclitaxel is very effective at targeting circulating tumor cells and inhibiting lung metastasis in breast-cancer models. These studies represent an important step toward the development of effective EphA2-targeting PDCs. PMID- 29470070 TI - Stereoelectronic Interactions Exhibited by 1 JC-H One-Bond Coupling Constants and Examination of the Possible Existence of the Intramolecular alpha-Effect in Six Membered Oxygen-Containing Heterocycles. AB - For more than five decades since its original conception, the alpha-effect has been advocated with arguments based on kinetic reactivity data. The present study was undertaken with the aim of gathering theoretical information on thermodynamic bond energy data in systems that could in principle give rise to intramolecular alpha-effects. In particular, oxygen-containing six-membered rings oxa-, 1,2 dioxa-, 1,3-dioxa-, 1,2,4-trioxa-, and 1,2,4,5-tetraoxacyclohexane were optimized at the B3LYP/aug-cc-pVTZ level of theory, and the magnitude of all C-H one-bond coupling constants was determined. Furthermore, hyperconjugative interactions were evaluated with Natural Bond Orbital analysis. Analysis of the collected information leads to the conclusion that ether oxygens are apparently better donors than peroxide oxygens; that is, the n(O) -> sigma*(C-Hax) two-orbital/two electron interaction seems to be stronger than the n(O-O) -> sigma*(C-Hax) two orbital/two-electron interaction, and this finding is contrary to expectations in terms of the alpha-effect. PMID- 29470071 TI - Isomeric Broadening of C60+ Electronic Excitation in Helium Droplets: Experiments Meet Theory. AB - Helium is considered an almost ideal tagging atom for cold messenger spectroscopy experiments. Although helium is bound very weakly to the ionic molecule of interest, helium tags can lead to shifts and broadenings that we recorded near 963.5 nm in the electronic excitation spectrum of C60+ solvated with up to 100 helium atoms. Dedicated quantum calculations indicate that the inhomogeneous broadening is due to different binding energies of helium to the pentagonal and hexagonal faces of C60+, their dependence on the electronic state, and the numerous isomeric structures that become available for intermediate coverage. Similar isomeric effects can be expected for optical spectra of most larger molecules surrounded by nonabsorbing weakly bound solvent molecules, a situation encountered in many messenger-tagging spectroscopy experiments. PMID- 29470072 TI - Molecular Imaging of Cancer Using X-ray Computed Tomography with Protease Targeted Iodinated Activity-Based Probes. AB - X-ray computed tomography (CT) is a robust, precise, fast, and reliable imaging method that enables excellent spatial resolution and quantification of contrast agents throughout the body. However, CT is largely inadequate for molecular imaging applications due mainly to its low contrast sensitivity that forces the use of large concentrations of contrast agents for detection. To overcome this limitation, we generated a new class of iodinated nanoscale activity-based probes (IN-ABPs) that sufficiently accumulates at the target site by covalently binding cysteine cathepsins that are exceptionally highly expressed in cancer. The IN ABPs are comprised of a short targeting peptide selective to specific cathepsins, an electrophilic moiety that allows activity-dependent covalent binding, and tags containing dendrimers with up to 48 iodine atoms. IN-ABPs selectively bind and inhibit activity of recombinant and intracellular cathepsin B, L, and S. We compared the in vivo kinetics, biodistribution, and tumor accumulation of IN-ABPs bearing 18 and 48 iodine atoms each, and their control counterparts lacking the targeting moiety. Here we show that although both IN-ABPs bind specifically to cathepsins within the tumor and produce detectable CT contrast, the 48-iodine bearing IN-ABP was found to be optimal with signals over 2.1-fold higher than its nontargeted counterpart. In conclusion, this study shows the synthetic feasibility and potential utility of IN-ABPs as potent contrast agents that enable molecular imaging of tumors using CT. PMID- 29470073 TI - Molecular Hydrogen Yields from the alpha-Self-Radiolysis of Nitric Acid Solutions Containing Plutonium or Americium. AB - The yield of molecular hydrogen, as a function of nitric acid concentration, from the alpha-radiolysis of aerated nitric acid and its mixtures with sulfuric acid containing plutonium or americium has been investigated. Comparison of experimental measurements with predictions of a Monte Carlo radiation track chemistry model shows that, in addition to scavenging of the hydrated electron, its precursor, and the hydrogen atom, the quenching of excited state water is important in controlling the yield of molecular hydrogen. In addition, increases in solution acidity cause a significant change in the track reactions, which can be explained as resulting from scavenging of eaq- by Haq+ to form H*. Although plutonium has been shown to be an effective scavenger of precursors of molecular hydrogen below 0.1 mol dm-3 nitrate, previously reported effects of plutonium on G(H2)alpha between 1 and 10 mol dm-3 nitric acid were not reproduced. Modeling results suggest that plutonium is unlikely to effectively compete with nitrate ions in scavenging the precursors of molecular hydrogen at higher nitric acid concentrations, and this was confirmed by comparing molecular hydrogen yields from plutonium solutions with those from americium solutions. Finally, comparison between radionuclide, ion accelerator experiments, and model predictions leads to the conclusion that the high dose rate of accelerator studies does not significantly affect the measured molecular hydrogen yield. These reactions provide insight into the important processes for liquors common in the reprocessing of spent nuclear fuel and the storage of highly radioactive liquid waste prior to vitrification.

PMID- 29470075 TI - Combined Experimental-Theoretical Study of the OH + CO -> H + CO2 Reaction Dynamics. AB - A combined experimental-theoretical study is performed to advance our understanding of the dynamics of the prototypical tetra-atom, complex-forming reaction OH + CO -> H + CO2, which is also of great practical relevance in combustion, Earth's atmosphere, and, potentially, Mars's atmosphere and interstellar chemistry. New crossed molecular beam experiments with mass spectrometric detection are analyzed together with the results from previous experiments and compared with quasi-classical trajectory (QCT) calculations on a new, full-dimensional potential energy surface (PES). Comparisons between experiment and theory are carried out both in the center-of-mass and laboratory frames. Good agreement is found between experiment and theory, both for product angular and translational energy distributions, leading to the conclusion that the new PES is the most accurate at present in elucidating the dynamics of this fundamental reaction. Yet, small deviations between experiment and theory remain and are presumably attributable to the QCT treatment of the scattering dynamics.

PMID- 29470077 TI - Efficient Upper-Excited State Fluorescence in an Organic Hyperbolic Metamaterial. AB - Upper-excited state emission is not usually observed from molecules owing to competition with much faster nonradiative relaxation pathways; however, it can be made more efficient by modifying the photonic density of states to enhance the radiative decay rate. Here, we show that embedding the small molecule zinc tetraphenylporphyrin (ZnTPP) in a hyperbolic metamaterial enables an ~18-fold increase in fluorescence intensity from the second singlet excited state ( S2) relative to that from the lowest singlet excited state ( S1). By varying the number of periods in the HMM stack, we are able to systematically tune the ZnTPP fluorescence spectrum from red (dominated by emission from S1) to blue (dominated by emission from S2) with an instrument-limited decay lifetime <10 ps. Our results are consistent with a broadband Purcell enhancement in the radiative rate of both transitions predicted via transfer matrix modeling and point to a general opportunity to harness upper-excited states for spectrally tunable, ultrafast fluorescence via radiative decay engineering. PMID- 29470078 TI - Engineering DNA Molecule Bridge between Metal Electrodes for High-Performance Molecular Transistor: An Environmental Dependent Approach. AB - Molecule-based transistors have attracted much attention due to their exclusive properties. Creation of a molecular transistor as well as engineering its structure have become one of the greatest aims of scientists. We have focused on the environmental dependent behavior of a DNA-templated transistor. Using the statistical distribution of the energy levels, we were able to distinguish the delocalized states of charge carriers and the transition between the localized and delocalized behaviors. On the other hand, we can determine the stability conditions of our quantum dynamical system. The results are verified by the inverse participation ratio method. Therefore, the most appropriate parameters for designing the DNA transistor are chosen. The DNA sequence is an important factor for its transport properties, but the results have shown that in the presence of the bath, the bath parameters are important, too. As is shown, it is possible that via the adjustment of bath parameters, one can design a conductivity channel for all nucleotide contents. Thus, one can engineer a DNA based transistor simply through the setting of only one parameter.

Scott has discovered the 1,2-swapping of carbon and hydrogen atoms which is known to take place on benzenoid aromatics (up to ~1000 degrees C range). For example, 13C-1-naphthalene is specifically converted to 13C-2-naphthalene, and there is evidence that this occurs through the formation of benzofulvene and a naphthalene-carbene intermediate. Application of the bent bond/antiperiplanar hypothesis leads to the postulate that higher in energy pyramidal singlet diradical intermediates can be used to propose a mechanism that rationalizes various atom rearrangements on benzenoid aromatics and related isomeric compounds. PMID- 29470084 TI - Synthesis of High Relaxivity Gadolinium AAZTA Tetramers as Building Blocks for Bioconjugation. AB - Molecular imaging requires the specific accumulation of contrast agents at the target. To exploit the superb resolution of MRI for applications in molecular imaging, gadolinium chelates, as the MRI contrast agents (CA), have to be conjugated to a specific vector able to recognize the epitope of interest. Several Gd(III)-chelates can be chemically linked to the same binding vector in order to deliver multiple copies of the CA (multimers) in a single targeting event thus increasing the sensitivity of the molecular probe. Herein three novel bifunctional agents, carrying one functional group for the bioconjugation to targeting vectors and four Gd(III)-AAZTA chelate functions for MRI contrast enhancement (AAZTA = 6-amino-6-methylperhydro-1,4-diazepinetetraacetic acid), are reported. The relaxivity in the tetrameric derivatives is 16.4 +/- 0.2 mMGd-1 s-1 at 21.5 MHz and 25 degrees C, being 2.4-fold higher than that of parent, monomeric Gd(III)-AAZTA. These compounds can be used as versatile building blocks to insert preformed, high relaxivity, and high density Gd-centers to biological targeting vectors. As an example, we describe the use of these bifunctional Gd(III)-chelates to label a fibrin-targeting peptide.

AB - The endo and exo stereoselectivities of Diels-Alder reactions of cyclopropenone, iminocyclopropene, and substituted triafulvenes with butadiene were rationalized using density functional theory calculations. When cyclopropenone is the dienophile, there is a 1.8 kcal/mol preference for the exo cycloaddition with butadiene, while the reaction of 3-difluoromethylene triafulvene with butadiene favors the endo cycloaddition by 2.8 kcal/mol. The influence of charge transfer and secondary orbital interactions on the stereoselectivity of Diels-Alder reactions involving triafulvenes and heteroanalogs is discussed. The predicted stereoselectivity correlates with both the charge and highest occupied molecular orbital (HOMO) coefficient at the C3 carbon of the triafulvene motif. PMID- 29470086 TI - Computational Study on N-N Homolytic Bond Dissociation Enthalpies of Hydrazine Derivatives. AB - The hydrazine derivatives have been regarded as the important building blocks in organic chemistry for the synthesis of organic N-containing compounds. It is important to understand the structure-activity relationship of the thermodynamics of N-N bonds, in particular, their strength as measured by using the homolytic bond dissociation enthalpies (BDEs). We calculated the N-N BDEs of 13 organonitrogen compounds by eight composite high-level ab initio methods including G3, G3B3, G4, G4MP2, CBS-QB3, ROCBS-QB3, CBS-Q, and CBS-APNO. Then 25 density functional theory (DFT) methods were selected for calculating the N-N BDEs of 58 organonitrogen compounds. The M05-2X method can provide the most accurate results with the smallest root-mean-square error (RMSE) of 8.9 kJ/mol. Subsequently, the N-N BDE predictions of different hydrazine derivatives including cycloalkylhydrazines, N-heterocyclic hydrazines, arylhydrazines, and hydrazides as well as the substituent effects were investigated in detail by using the M05-2X method. In addition, the analysis including the natural bond orbital (NBO) as well as the energies of frontier orbitals were performed in order to further understand the essence of the N-N BDE change patterns. PMID- 29470087 TI - Nature of Large Temporal Fluctuations of Hydrogen Transfer Rates in Single Molecules. AB - Double hydrogen transfer was monitored in single molecules of parent porphycene and its tetra- t-butyl derivative using confocal fluorescence microscopy. The molecules have been embedded in a polymer matrix. Under such conditions, a significant fraction of the population reveals a huge decrease of the tautomerization rate with respect to the value obtained from ensemble studies in solution. This effect is explained by a model that assumes that the rate is determined by the reorganization coordinate that involves slow relaxation of the polymer matrix. The model provides indirect evidence for the dominant role of tunneling. It is proposed that tautomerization in single molecules of the porphycene family can be used to probe polymer relaxation dynamics on the time scale ranging from picoseconds to minutes.

AB - Stereocalpin A is a cyclic depsipeptide with cytotoxic activity isolated from the Antarctic lichen Stereocaulon alpinum. Although a number of synthetic investigations of the unprecedented 12-membered macrocycle of stereocalpin A with a dipeptide segment and a polyketide substructure have been conducted, the configurational assignment has not been completed. In this study, we achieved the first total synthesis and stereochemical revision of stereocalpin A. To facilitate the comprehensive assessment of eight possible stereocalpin A isomers, four stereoisomers of polyketide precursors were conjugated with l-Phe-l-MePhe and d-Phe-d-MePhe dipeptides (MePhe: N-methylphenylalanine) to provide four possible isomers and four mirror-image structures of the remaining isomers, respectively. The comparative NMR analysis of a series of stereoisomers revealed that stereocalpin A possesses 2 R,4 S,5 R-configurations, which is unique among the related 12-membered hybrid peptide-polyketide natural products reported recently. The NOE correlations in the polyketide substructure of stereocalpin A were also retrospectively analyzed among the eight possible stereoisomers.

AB - Efficient polarization of organic molecules is of extraordinary relevance when performing nuclear magnetic resonance (NMR) and imaging. Commercially available routes to dynamical nuclear polarization (DNP) work at extremely low temperatures, relying on the solidification of organic samples and thus bringing the molecules out of their ambient thermal conditions. In this work, we investigate polarization transfer from optically pumped nitrogen vacancy centers in diamond to external molecules at room temperature. This polarization transfer is described by both an extensive analytical analysis and numerical simulations based on spin bath bosonization and is supported by experimental data in excellent agreement. These results set the route to hyperpolarization of diffusive molecules in different scenarios and consequently, due to an increased signal, to high-resolution NMR. PMID- 29470090 TI - Engineering Interfacial Processes at Mini-Micro-Nano Scales Using Sessile Droplet Architecture. AB - Evaporating sessile functional droplets act as the fundamental building block that controls the cumulative outcome of many industrial and biological applications such as surface patterning, 3D printing, photonic crystals, and DNA sequencing, to name a few. Additionally, a drying single sessile droplet forms a high-throughput processing technique using low material volume which is especially suitable for medical diagnosis. A sessile droplet also provides an elementary platform to study and analyze fundamental interfacial processes at various length scales ranging from macroscopically observable wetting and evaporation to microfluidic transport to interparticle forces operating at a nanometric length scale. As an example, to ascertain the quality of 3D printing we must understand the fundamental interfacial processes at the droplet scale. In this article, we review the coupled physics of evaporation flow-contact-line driven particle transport in sessile colloidal droplets and provide methodologies to control the same. Through natural alterations in droplet vaporization, one can change the evaporative pattern and contact line dynamics leading to internal flow which will modulate the final particle assembly in a nontrivial fashion. We further show that control over particle transport can also be exerted by external stimuli which can be thermal, mechanical oscillations, vapor confinement (walled or a fellow droplet), or chemical (surfactant-induced) in nature. For example, significant augmentation of an otherwise evaporation-driven particle transport in sessile droplets can be brought about simply through controlled interfacial oscillations. The ability to control the final morphologies by manipulating the governing interfacial mechanisms in the precursor stages of droplet drying makes it perfectly suitable for fabrication-, mixing-, and diagnostic-based applications.

PMID- 29470092 TI - The Stroop test as a measure of performance validity in adults clinically referred for neuropsychological assessment. AB - This study was designed to develop performance validity indicators embedded within the Delis-Kaplan Executive Function Systems (D-KEFS) version of the Stroop task. Archival data from a mixed clinical sample of 132 patients (50% male; MAge = 43.4; MEducation = 14.1) clinically referred for neuropsychological assessment were analyzed. Criterion measures included the Warrington Recognition Memory Test Words and 2 composites based on several independent validity indicators. An age corrected scaled score <=6 on any of the 4 trials reliably differentiated psychometrically defined credible and noncredible response sets with high specificity (.87-.94) and variable sensitivity (.34-.71). An inverted Stroop effect was less sensitive (.14-.29), but comparably specific (.85-90) to invalid performance. Aggregating the newly developed D-KEFS Stroop validity indicators further improved classification accuracy. Failing the validity cutoffs was unrelated to self-reported depression or anxiety. However, it was associated with elevated somatic symptom report. In addition to processing speed and executive function, the D-KEFS version of the Stroop task can function as a measure of performance validity. A multivariate approach to performance validity assessment is generally superior to univariate models. (PsycINFO Database Record PMID- 29470093 TI - Hemispheric asymmetries in setticlavio reading. AB - Musical setticlavio (literally, seven clefs) reading refers to the ability to read (i.e., to say aloud, without to sing) the musical note labels in the 7 musical clefs. The present research report aims to investigate hemispheric asymmetries in such a basic musical ability, very poorly investigated in the domain of cognitive neurosciences. Sixty-three musicians underwent lateralized tachistoscopic presentation of musical notes on staves, 50% in the left and 50% in the right visual field, associated with each of the 7 musical clefs. The subjects' task was to pronounce as fast as possible the name of the presented note, taking into account the current clef symbol. Mixed directions of asymmetry with different involvements of the left and right hemisphere in each clef were observed. Whereas reading in the treble, bass, alto, tenor, and mezzosoprano clef showed no lateral asymmetries, a left hemisphere asymmetry was observed with the soprano clef and a right hemisphere asymmetry with the baritone clef. This effect was observed with accuracy but not with reaction time. These results suggest that there is not a univocal hemispheric balance in musical setticlavio reading, reflecting several possible underlying reading mechanisms. Moreover, inversely proportional results between performance (both accuracy and reaction time) and distance from the reference clef (treble) suggest that setticlavio reading is based on a spatial rather than verbal code.

The aim of this study was to determine accuracy (compared to self-monitoring of blood glucose [SMBG]), clinical safety, and acceptability of the FreeStyle Libre System when used at home by this population. MATERIALS AND METHODS: Seventy-four participants, with type 1 (T1D, n = 24), type 2 (T2D, n = 11), or gestational (n = 39) diabetes, were enrolled across 13 sites (9 in United Kingdom, 4 in Austria). Average gestation was 26.6 +/- 6.8 weeks (mean +/- standard deviation), age was 30.5 +/- 5.1 years, diabetes duration was 13.1 +/- 7.3 years for T1D and 3.2 +/- 2.5 years for T2D, and 49/74 (66.2%) used insulin to manage their diabetes. Sensors were worn for up to 14 days. Sensor glucose values (masked) were compared with capillary SMBG values (made at least 4 times/day). RESULTS: Clinical accuracy of sensor results versus SMBG results was demonstrated, with 88.1% and 99.8% of results within Zone A and Zones A and B of the Consensus Error Grid, respectively. Overall mean absolute relative difference was 11.8%. Sensor accuracy was unaffected by the type of diabetes, the stage of pregnancy, whether insulin was used, age or body mass index. User questionnaires indicated high levels of satisfaction with sensor wear, system use, and comparison to SMBG. There were no unanticipated device-related adverse events. CONCLUSIONS: Good agreement was demonstrated between the FreeStyle Libre System and SMBG. Accuracy of the system was unaffected by patient characteristics, indicating that the system is safe and accurate to use by pregnant women with diabetes. PMID- 29470095 TI - Subacromial Local Anesthetics Do Not Interfere With Rotator Cuff Healing After Arthroscopic Repair. AB - BACKGROUND: Subacromial pain pumps are used for analgesia after arthroscopic rotator cuff surgery. However, there is controversy about myotoxic or tendinotoxic effects of local anesthetics. HYPOTHESIS: Ropivacaine administered via a subacromial pain pump would have no adverse effect on rotator cuff tendon healing, fatty degeneration, strength, or functional outcomes after arthroscopic repair. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: This study continues follow-up of patients enrolled in the authors' 3 published prospective studies regarding pain control after arthroscopic rotator cuff repair. In total, 118 patients who underwent rotator cuff repair and returned for evaluation at least 1 year postoperatively were divided into 3 groups: patients who received continuous subacromial ropivacaine infusion (group 1, n = 33), those who received patient-controlled subacromial ropivacaine infusion (group 2, n = 30), and those who received other pain control modalities (intravenous patient-controlled analgesia and/or interscalene block; group 3, n = 55). At least 1 year postoperatively, tendon healing and changes in global fatty degeneration index (GFDI) were estimated through computed tomographic arthrography, magnetic resonance imaging, or ultrasonography. Changes in isokinetic muscle performance test (IMPT) were calculated and functional outcomes evaluated, including visual analog scales (VASs) for pain and satisfaction, American Shoulder and Elbow Surgeons score, and Constant score. RESULTS: At final follow-up, there were no differences in pain VAS (group 1, 1.1 +/- 2.3; group 2, 1.3 +/- 1.9; group 3, 0.9 +/- 1.7; P = .88), satisfaction VAS (group 1, 8.3 +/- 2.4; group 2, 8.7 +/- 1.5; group 3, 8.0 +/- 2.1; P = .64), American Shoulder and Elbow Surgeons score (group 1, 79.5 +/- 10.5; group 2, 81.1 +/- 6.9; group 3, 75.7 +/- 7.6; P = .34), or Constant score (group 1, 81.8 +/- 8.7; group 2, 77.6 +/- 9.3; group 3, 78.2 +/- 8.4; P = .31). Among the 3 groups, there were no significant differences in healing rates (group 1, 72.7%; group 2, 73.3%; group 3, 70.9%; P = .83) and no differences in changes of GFDI (group 1, 0.45; group 2, 0.62; group 3, 0.41; P = .79), and IMPT (abduction: group 1, 113.0%; group 2, 121.5%; group 3, 120.1%; P = .73; external rotation: group 1, 112.1%; group 2, 121.6%; group 3, 111.7%; P = .71; internal rotation: group 1, 118.2%; group 2, 118.0%; group 3, 118.1%; P = .95). When data were reanalyzed with 2 groups (group 1 + 2 vs group 3), there were no significant differences in functional scores, healing rates, or changes in GFDI and IMPT ( P > .05). CONCLUSION: Current data suggest that myotoxicity of subacromial ropivacaine administered via pain pump may be reversible or may not be so severe as to interfere with tendon healing and cause muscle degeneration and thus may not affect postoperative function. PMID- 29470096 TI - The psychometric properties, sensitivity and specificity of the geriatric anxiety inventory, hospital anxiety and depression scale, and rating anxiety in dementia scale in aged care residents. AB - OBJECTIVES: Limited research has been conducted into the identification of a valid and reliable screening measure for anxiety in aged care settings, despite it being one of the most common psychological conditions. This study aimed to determine an appropriate anxiety screening tool for aged care by comparing the reliability and validity of three commonly used measures and identifying specific cut-offs for the identification of generalized anxiety disorder (GAD). METHOD: One-hundred and eighty nursing home residents (M age = 85.39 years) completed the GAI, HADS-A, and RAID, along with a structured diagnostic interview. RESULTS: Twenty participants (11.1%) met DSM-5 criteria for GAD. All measures had good psychometric properties , although reliability estimates for the HADS-A were sub optimal. Privileging sensitivity , the GAI cut-off score of 9 gave sensitivity of 90.0% and specificity of 86.3%; HADS-A cut-off of 6 gave sensitivity of 90.0% and specificity of 80.6%; and RAID cut-off of 11 gave sensitivity of 85.0% and specificity of 72.5%. CONCLUSION: While all three measures had adequate reliability, validity, and cut-scores with high levels of sensitivity and specificity to detect anxiety within aged care, the GAI was the most consistently reliable and valid measure for screening for GAD. PMID- 29470097 TI - A novel minimally invasive method of successful tissue glue injection in patients with iatrogenic pseudoaneurysm. AB - OBJECTIVE: To investigate the efficacy and safety of ultrasound-guided tissue glue injection for the treatment of iatrogenic femoral artery pseudoaneurysm. METHODS: The study comprised of nine patients with unsuccessful ultrasound-guided thrombin injection and one patient with rapidly progressing anemia. All patients had undergone recanalization procedures at least twice, including two subjects with a very rapidly enlarging pseudoaneurysm lobe or significant anemia. Tissue glue at a dose of 0.9 +/- 0.53 ml was injected under ultrasound guidance in each patient. RESULTS: Complete embolization was achieved in all patients. Follow-up ultrasound performed 24 h later as well as at 1 and 2 weeks did not show recurrent reperfusion of the pseudoaneurysm. CONCLUSION: Embolization of iatrogenic pseudoaneurysm using tissue glue seems to be an effective technique for the treatment of this complication. It might be considered as a treatment option in case of unsuccessful primary repair by means of thrombin injection orhemorrhagic shock due to rapid aneurysm progression. Advances in knowledge: Patients with multiple recanalizations and those with dynamically enlarging pseudoaneurysm or rapidly progressing anemia are at risk of life-threatening bleeding. An ultrasound-guided tissue glue injection, a novel method for the treatment of femoral artery pseudoaneurysm, might be considered as a treatment option especially in case of primary thrombin injection failure. PMID- 29470098 TI - Large datasets, logistics, sharing and workflow in screening. AB - Cancer screening initiatives exist around the world for different malignancies, most frequently breast, colorectal, and cervical cancer. A number of cancer registries exist to collect relevant data, but while these data may include imaging findings, they rarely, if ever, include actual images. Additionally, the data submitted to the registry are usually correlated with eventual cancer diagnoses and patient outcomes, rather than used with the individual's future screenings. Developing screening programs that allow for images to be submitted to a central location in addition to patient meta data and used for comparison to future screening exams would be very valuable in increasing access to care and ensuring that individuals are effectively screened at appropriate intervals. It would also change the way imaging results and additional patient data are correlated to eventual outcomes. However, it introduces logistical challenges surrounding secure storage and transmission of data to subsequent screening sites. In addition, in the absence of standardized protocols for screening, comparing current and prior imaging, especially from different equipment, can be challenging. Implementing a large-scale screening program with an image-enriched screening registry-effectively, an image-enriched electronic screening record also requires that incentives exist for screening sites, physicians, and patients to participate; to maximize coverage, participation may have to be supported by government agencies. Workflows will also have to be adjusted to support registry participation for all screening patients in an effort to create a large, robust data set that can be used for future screening efforts as well as research initiatives.center. PMID- 29470099 TI - Doses from cervical spine computed tomography (CT) examinations in the UK. AB - OBJECTIVE: To review doses to patients undergoing cervical spine CT examinations in the UK. METHODS: A data collection form was developed and distributed to medical physicists and radiographers via e-mail distribution lists. The form requested details of CT scanners, exposure protocols and patient dose index information. RESULTS: Data were received for 73 scanners. It was seen that 97% of scanners used automatic exposure control, and 60% of scanners used an iterative reconstruction technique for cervical spine examinations. The majority of scans were taken at 120 kV. The average patient dose indicators in terms of CT dose index (CTDIvol) ranged from 3.5 to 39.7 mGy (mean value 16.7 mGy), and for the DLP, ranged from 87 to 1030 mGy cm (mean value 379 mGy cm) as quoted for the standard 32 cm phantom. CONCLUSION: The rounded third quartile value of the mean dose distributions from this study were a CT dose index (CTDIvol) of 20 mGy and a dose-length product of 440 mGy cm as quoted for a 32 cm body phantom. These are significantly higher than those in the 2011 Public Health England CT dose survey when adjusted for phantom size. It is suggested that the existing national diagnostic reference levels for cervical spine CT should be amended, both with the new values and also to quote according to the 32 cm phantom. Advances in knowledge: Proposed new national diagnostic reference levels are presented for cervical spine CT examinations. PMID- 29470100 TI - Radiation repair models for clinical application. AB - A number of newly emerging clinical techniques involve non-conventional patterns of radiation delivery which require an appreciation of the role played by radiation repair phenomena. This review outlines the main models of radiation repair, focussing on those which are of greatest clinical usefulness and which may be incorporated into biologically effective dose assessments. The need to account for the apparent "slowing-down" of repair rates observed in some normal tissues is also examined, along with a comparison of the relative merits of the formulations which can be used to account for such phenomena. Jack Fowler brought valuable insight to the understanding of radiation repair processes and this article includes reference to his important contributions in this area. PMID- 29470101 TI - Ebselen Reversibly Inhibits Human Glutamate Dehydrogenase at the Catalytic Site. AB - Human glutamate dehydrogenase (GDH) plays an important role in neurological diseases, tumor metabolism, and hyperinsulinism-hyperammonemia syndrome (HHS). However, there are very few inhibitors known for human GDH. Recently, Ebselen was reported to crosslink with Escherichia coli GDH at the active site cysteine residue (Cys321), but the sequence alignment showed that the corresponding residue is Ala329 in human GDH. To investigate whether Ebselen could be an inhibitor for human GDH, we cloned and expressed an N-terminal His-tagged human GDH in E. coli. The recombinant human GDH enzyme showed expected properties such as adenosine diphosphate activation and nicotinamide adenine dinucleotide/nicotinamide adenine dinucleotide phosphate dual recognition. Further, we developed a 2-(3-(2-methoxy-4-nitrophenyl)-2-(4-nitrophenyl)-2H tetrazol-3-ium-5-yl) benzenesulfonate sodium salt (EZMTT)-based assay for human GDH, which was highly sensitive and is suitable for high-throughput screening for potent GDH inhibitors. In addition, ForteBio binding assays demonstrated that Ebselen is a reversible active site inhibitor for human GDH. Since Ebselen is a multifunctional organoselenium compound in Phase III clinical trials for inflammation, an Ebselen-based GDH inhibitor might be valuable for future drug discovery for HHS patients. PMID- 29470102 TI - What You Don't Notice Can Harm You: Age-Related Differences in Detecting Concurrent Visual, Auditory, and Tactile Cues. AB - Objective This research sought to determine whether people can perceive and process three nonredundant (and unrelated) signals in vision, hearing, and touch at the same time and how aging and concurrent task demands affect this ability. Background Multimodal displays have been shown to improve multitasking and attention management; however, their potential limitations are not well understood. The majority of studies on multimodal information presentation have focused on the processing of only two concurrent and, most often, redundant cues by younger participants. Method Two experiments were conducted in which younger and older adults detected and responded to a series of singles, pairs, and triplets of visual, auditory, and tactile cues in the absence (Experiment 1) and presence (Experiment 2) of an ongoing simulated driving task. Detection rates, response times, and driving task performance were measured. Results Compared to younger participants, older adults showed longer response times and higher error rates in response to cues/cue combinations. Older participants often missed the tactile cue when three cues were combined. They sometimes falsely reported the presence of a visual cue when presented with a pair of auditory and tactile signals. Driving performance suffered most in the presence of cue triplets. Conclusion People are more likely to miss information if more than two concurrent nonredundant signals are presented to different sensory channels. Application The findings from this work help inform the design of multimodal displays and ensure their usefulness across different age groups and in various application domains. PMID- 29470103 TI - An Approach to Children with Pulmonary Edema at High Altitude. AB - : Liptzin, Deborah R., Steven H. Abman, Ann Giesenhagen, and D. Dunbar Ivy. An approach to children with pulmonary edema at high altitude. High Alt Med Biol. 19:91-98, 2018. INTRODUCTION: Diagnosis of high-altitude illness can be more challenging in children, especially those who are preverbal. Families often travel to high elevations for family vacations, either for skiing, hiking, and/or camping. They may present to their primary care providers looking for anticipatory guidance before travel or may follow-up after developing high altitude illness. High-altitude pulmonary edema (HAPE) can be fatal. OBSERVATIONS: There is no indication for HAPE prophylaxis in altitude naive children. Children may develop HAPE either when traveling from low altitude to high altitude for vacation (classic HAPE), when returning to high-altitude homes after travel to low altitude (reentry HAPE), or even with a respiratory illness at high altitude without any change in elevation (high-altitude resident pulmonary edema or HARPE). Children may be more susceptible to HAPE because of increased vascular reactivity, immature control of breathing, and increased frequency of respiratory illnesses. Children with HAPE warrant evaluation for underlying cardiopulmonary abnormalities, including structural heart disease and pulmonary hypertension. Treatment of HAPE includes supplemental oxygen and descent, but underlying cardiopulmonary disease may also help guide treatment and prevention. CONCLUSIONS AND RELEVANCE: Evaluation for structural heart disease and pulmonary hypertension should be considered in children with HAPE. Future studies should be done to elucidate the optimal strategies for prevention and treatment of HAPE and to better understand the development of HAPE in children. PMID- 29470104 TI - Association Between Utilization of Chiropractic Services for Treatment of Low Back Pain and Use of Prescription Opioids. AB - OBJECTIVE: Pain relief resulting from services delivered by doctors of chiropractic may allow patients to use lower or less frequent doses of opioids, leading to reduced risk of adverse effects. The objective of this investigation was to evaluate the association between utilization of chiropractic services and the use of prescription opioid medications. DESIGN: The authors used a retrospective cohort design to analyze health insurance claims data. SETTING: The data source was the all payer claims database administered by the State of New Hampshire. The authors chose New Hampshire because health claims data were readily available for research, and in 2015, New Hampshire had the second-highest age-adjusted rate of drug overdose deaths in the United States. SUBJECTS: The study population comprised New Hampshire residents aged 18-99 years, enrolled in a health plan, and with at least two clinical office visits within 90 days for a primary diagnosis of low-back pain. The authors excluded subjects with a diagnosis of cancer. OUTCOME MEASURES: The authors measured likelihood of opioid prescription fill among recipients of services delivered by doctors of chiropractic compared with nonrecipients. They also compared the cohorts with regard to rates of prescription fills for opioids and associated charges. RESULTS: The adjusted likelihood of filling a prescription for an opioid analgesic was 55% lower among recipients compared with nonrecipients (odds ratio 0.45; 95% confidence interval 0.40-0.47; p < 0.0001). Average charges per person for opioid prescriptions were also significantly lower among recipients. CONCLUSIONS: Among New Hampshire adults with office visits for noncancer low-back pain, the likelihood of filling a prescription for an opioid analgesic was significantly lower for recipients of services delivered by doctors of chiropractic compared with nonrecipients. The underlying cause of this correlation remains unknown, indicating the need for further investigation. PMID- 29470105 TI - Diabetes Mellitus m-Health Applications: A Systematic Review of Features and Fundamentals. AB - BACKGROUND: The increasing number of diabetes mellitus (DM) m-health applications (apps) reveals a panorama of different approaches to the subject, demonstrating dynamism and heterogeneity. Available applications have various functions, capabilities, and data collection techniques. OBJECTIVE: We systematically reviewed the literature to identify and analyze studies regarding the diversity of applications aimed at DM monitoring and treatment. We aimed to investigate app functionalities, the basis for their design, and how they were tested. MATERIALS AND METHODS: We conducted a systematic literature review in Association for Computing Machinery (ACM), Institute of Electrical and Electronics Engineers (IEEE), ScienceDirect, Springer, and Medical Literature Analysis and Retrieval System Online (MEDLINE) databases. The search considered studies published until April 2017, without language restrictions. RESULTS: After removal of duplicates, 679 studies were screened and assessed for eligibility, when 39 studies met the inclusion criteria. We present tables summarizing the functionalities, features, fundamental techniques, and methods. CONCLUSIONS: There is a variety of approaches used in the DM apps, with comprehensive, customizable, and adjusted functionalities for different purposes. Most apps are digital logbooks for collecting data on various daily tasks from DM treatment. The researchers are interested in guidelines of medical organizations, evaluations from health professionals and patients, and other methods to verify accuracy and reliability.

PMID- 29470107 TI - Leptospira Genomospecies and Sequence Type Prevalence in Small Mammal Populations in Germany. AB - Leptospirosis is a worldwide emerging infectious disease caused by zoonotic bacteria of the genus Leptospira. Numerous mammals, including domestic and companion animals, can be infected by Leptospira spp., but rodents and other small mammals are considered the main reservoir. The annual number of recorded human leptospirosis cases in Germany (2001-2016) was 25-166. Field fever outbreaks in strawberry pickers, due to infection with Leptospira kirschneri serovar Grippotyphosa, were reported in 2007 and 2014. To identify the most commonly occurring Leptospira genomospecies, sequence types (STs), and their small mammal host specificity, a monitoring study was performed during 2010-2014 in four federal states of Germany. Initial screening of kidney tissues of 3,950 animals by PCR targeting the lipl32 gene revealed 435 rodents of 6 species and 89 shrews of three species positive for leptospiral DNA. PCR-based analyses resulted in the identification of the genomospecies L. kirschneri (62.7%), Leptospira interrogans (28.3%), and Leptospira borgpetersenii (9.0%), which are represented by four, one, and two STs, respectively. The average Leptospira prevalence was highest (~30%) in common voles (Microtus arvalis) and field voles (Microtus agrestis). Both species were exclusively infected with L. kirschneri. In contrast, in bank voles (Myodes glareolus) and yellow-necked mice (Apodemus flavicollis), DNA of all three genomospecies was detected, and in common shrews (Sorex araneus) DNA of L. kirschneri and L. borgpetersenii was identified. The association between individual infection status and demographic factors varied between species; infection status was always positively correlated to body weight. In conclusion, the study confirmed a broad geographical distribution of Leptospira in small mammals and suggested an important public health relevance of common and field voles as reservoirs of L. kirschneri. Furthermore, the investigations identified seasonal, habitat-related, as well as individual influences on Leptospira prevalence in small mammals that might impact public health. PMID- 29470109 TI - Determinants of the Intention of Senegal's Physicians to Use Telemedicine in Their Professional Activities. AB - BACKGROUND: In Senegal, physicians are unevenly distributed, leading to unequal access to healthcare in underserved areas. Telemedicine is seen as a potential means to address this problem. INTRODUCTION: Telemedicine's potential to improve access depends, in part, on physicians' intention to use the technology. In Senegal that intention is not well known. This study aimed to determine that intention and the factors that influence it. MATERIALS AND METHODS: We conducted a cross-sectional study between January and February 2015 with a random sample of 168 physicians working in public hospitals and 153 in district health centers in Senegal. Data were collected using two questionnaires and analyzed using descriptive statistics, correlations, and linear regression. RESULTS: The intention to use telemedicine by physicians working in public hospitals and district health centers was moderate and was positively correlated with their attitude, subjective norm, and perceived behavioral control. The intention of the physicians working in public hospitals was also positively correlated with their region and status as contract employee, but negatively with their status as government employee. That of the physicians working in district health centers was negatively correlated with their age and years of practice. DISCUSSION: These results showed that, overall, the intention of Senegal's physicians to use telemedicine was moderate and could be improved by acting on factors related to their perceived behavioral control and other factors correlated with their intention. CONCLUSIONS: Physicians' intention to use telemedicine in Senegal is fair but could be improved by addressing the factors identified in this study. PMID- 29470108 TI - Application of 80-kVp scan and raw data-based iterative reconstruction for reduced iodine load abdominal-pelvic CT in patients at risk of contrast-induced nephropathy referred for oncological assessment: effects on radiation dose, image quality and renal function. AB - OBJECTIVE: To evaluate the image quality, radiation dose, and renal safety of contrast medium (CM)-reduced abdominal-pelvic CT combining 80-kVp and sinogram affirmed iterative reconstruction (SAFIRE) in patients with renal dysfunction for oncological assessment. METHODS: We included 45 patients with renal dysfunction (estimated glomerular filtration rate <45 ml per min per 1.73 m2) who underwent reduced-CM abdominal-pelvic CT (360 mgI kg-1, 80-kVp, SAFIRE) for oncological assessment. Another 45 patients without renal dysfunction (estimated glomerular filtration rate >60 ml per lmin per 1.73 m2) who underwent standard oncological abdominal-pelvic CT (600 mgI kg-1, 120-kVp, filtered-back projection) were included as controls. CT attenuation, image noise, and contrast-to-noise ratio (CNR) were compared. Two observers performed subjective image analysis on a 4 point scale. Size-specific dose estimate and renal function 1-3 months after CT were measured. RESULTS: The size-specific dose estimate and iodine load of 80-kVp protocol were 32 and 41%,, respectively, lower than of 120-kVp protocol (p < 0.01). CT attenuation and contrast-to-noise ratio of parenchymal organs and vessels in 80-kVp images were significantly better than those of 120-kVp images (p < 0.05). There were no significant differences in quantitative or qualitative image noise or subjective overall quality (p > 0.05). No significant kidney injury associated with CM administration was observed. CONCLUSION: 80-kVp abdominal-pelvic CT with SAFIRE yields diagnostic image quality in oncology patients with renal dysfunction under substantially reduced iodine and radiation dose without renal safety concerns. Advances in knowledge: Using 80-kVp and SAFIRE allows for 40% iodine load and 32% radiation dose reduction for abdominal pelvic CT without compromising image quality and renal function in oncology patients at risk of contrast-induced nephropathy. PMID- 29470110 TI - Zika-Associated Microcephaly Epidemic and Birth Rate Reduction in Brazilian Cities. AB - OBJECTIVES: To estimate birth reduction potentially in response to Zika virus associated microcephaly among the 36 largest Brazilian cities. METHODS: We analyzed the number of live births per month on the basis of information on approximately 8.2 million births from all of Brazil's state capitals and cities that had more than 10 000 annual births. RESULTS: In the second half of 2016, the live birth rate was reduced by 7.78% (95% confidence interval [CI] = 6.64%, 8.89%; P < .001). This reduction was correlated with the Zika virus-associated microcephaly rate. In the cities with the highest microcephaly rate in 2015 (> 1 case per 1000 live births), the reduction in the live birth rate was 10.84% (95% CI = 8.58%, 13.04%). CONCLUSIONS: The birth rate in the largest Brazilian cities during the second half of 2016 was significantly reduced, which is potentially the effect of a birth control recommendation prompted by an epidemiological alert. Public Health Implications. The effects of population-based interventions should be weighed by considering the actual risk of disease and the sociodemographic impact of strategies such as birth control. PMID- 29470111 TI - Long-Acting Reversible Contraception Free of Charge, Method Initiation, and Abortion Rates in Finland. AB - OBJECTIVES: To evaluate whether a public program providing long-acting reversible contraceptive (LARC) methods free of charge increases the LARC initiation rate and reduces the unintended pregnancy rate in the general population. METHODS: Since 2013, all women in Vantaa, Finland, have been entitled to 1 LARC method free of charge. With time-series analysis between 2000 and 2015, we assessed whether this public program was associated with changes in steady-state mean rates of LARC initiation and abortions. RESULTS: The initiation rate of LARCs (1/1000 women) increased 2.2-fold from 1.9 to 4.2 after the intervention (P < .001). Concomitantly, the abortion rate (1/1000 women) declined by 16% from 1.1 to 0.9 in the total sample (P < .001), by 36% from 1.3 to 0.8 among those aged 15 to 19 years (P < .001), and by 14% from 2.0 to 1.7 among those aged 20 to 24 years (P = .01). CONCLUSIONS: The LARC program was associated with increased uptake of LARC methods and fewer abortions in the population. Public Health Implications. Entitling the population to LARC methods free of charge is an effective means to reduce the unmet need of contraception and the need for abortion, especially among women younger than 25 years. PMID- 29470112 TI - Cumulative Prevalence of Maltreatment Among New Zealand Children, 1998-2015. AB - OBJECTIVES: To document, via linked administrative data, the cumulative prevalence among New Zealand children of notifications to child protective services (CPS), substantiated maltreatment cases, and out-of-home placements. METHODS: We followed all children born in New Zealand in 1998 until the end of 2015 (an overall sample of 55 443 children). We determined the cumulative frequencies of notifications, substantiated maltreatment cases (by subtype), and first entries into foster care from birth through the age of 17 years. We also decomposed CPS involvement by gender. RESULTS: We found that almost 1 in 4 children had been subject to at least 1 report to CPS at age 17 years (23.5%), and 9.7% had been a victim of substantiated abuse or neglect. We also found that 3.1% had experienced out-of-home placements by age 17 years, with boys being more affected. CONCLUSIONS: Both notifications and substantiated child maltreatment are more common in New Zealand than is generally recognized, with the incidence of notifications higher than the incidence of medicated asthma among children and the prevalence of substantiations similar to the prevalence of obesity. PMID- 29470113 TI - Local-Level Adult Influenza and Pneumococcal Vaccination Disparities: Chicago, Illinois, 2015-2016. AB - OBJECTIVES: To investigate local-level adult influenza and pneumococcal vaccination disparities to inform targeted interventions. METHODS: Questions on influenza and pneumococcal vaccination uptake were included in a door-to-door community-based representative survey conducted in 10 Chicago, Illinois, neighborhoods in 2015 and 2016. A total of 1543 adults completed the survey, including 172 adults aged 65 years or older. We calculated adult influenza (>= 18 years) and pneumococcal (>= 65 years) vaccination coverage by community area and respondent characteristics. RESULTS: We observed significant differences in pneumococcal vaccination coverage between community areas (range = 18%-91%). Influenza vaccination coverage differed by gender, age, insurance coverage, acculturation, and confidence or trust in physician. Non-Hispanic Blacks were more likely to be vaccinated when they had higher confidence or trust in their physician (45% vs 20%; P < .01). Mexicans who reported less acculturation were more likely to be vaccinated than were Mexicans who were more acculturated (41% vs 27%; P = .02). CONCLUSIONS: Striking disparities between neighborhoods and racial/ethnic groups in adult influenza and pneumococcal vaccination coverage highlight the need for improved local-level immunization coverage data. PMID- 29470114 TI - State Law Approaches to Facility Regulation of Abortion and Other Office Interventions. AB - OBJECTIVES: To compare the prevalence and characteristics of facility laws governing abortion provision specifically (targeted regulation of abortion providers [TRAP] laws); office-based surgeries, procedures, sedation or anesthesia (office interventions) generally (OBS laws); and other procedures specifically. METHODS: We conducted cross-sectional legal assessments of state facility laws for office interventions in effect as of August 1, 2016. We coded characteristics for each law and compared characteristics across categories of laws. RESULTS: TRAP laws (n = 55; in 34 states) were more prevalent than OBS laws (n = 25; in 25 states) or laws targeting other procedures (n = 1; in 1 state). TRAP laws often regulated facilities that would not be regulated under OBS laws (e.g., all TRAP laws, but only 2 OBS laws, applied regardless of sedation or anesthesia used). TRAP laws imposed more numerous and more stringent requirements than OBS laws. CONCLUSIONS: Many states regulate abortion-providing facilities differently, and more stringently, than facilities providing other office interventions. The Supreme Court's 2016 decision in Whole Woman's Health v Hellerstedt casts doubt on the legitimacy of that differential treatment. PMID- 29470116 TI - Mechanisms by Which Anti-Immigrant Stigma Exacerbates Racial/Ethnic Health Disparities. AB - Anti-immigrant rhetoric and political actions gained prominence and public support before, during, and after the 2016 presidential election. This anti immigrant political environment threatens to increase health disparities among undocumented persons, immigrant groups, and people of color. I discuss the mechanisms by which anti-immigrant stigma exacerbates racial/ethnic health disparities through increasing multilevel discrimination and stress, deportation and detention, and policies that limit health resources. I argue that the anti immigrant sociopolitical context is a social determinant of health that affects mostly communities of color, both immigrants and nonimmigrants. Public health has a moral obligation to consider how immigration policy is health policy and to be prepared to respond to worsening health disparities as a result of anti-immigrant racism. PMID- 29470117 TI - Adaptive Behavior of Sheltered Homeless Children in the French ENFAMS Survey. AB - OBJECTIVES: To describe the adaptive behaviors in a large sample of homeless children and identify factors associated with developmental delay. METHODS: Data were from a cross-sectional survey of 557 children younger than 6 years randomly sampled among homeless sheltered families in the Paris region, France (January May 2013). An interviewer and a psychologist conducted face-to-face interviews to collect information on sociodemographic and health characteristics. We assessed adaptive behaviors using the Vineland Adaptive Behavior Scales, second edition (VABS-II). RESULTS: The mean VABS-II composite score (SD) was 75.4 (12.0), and most participating children (80.9%) were considered developmentally delayed. Characteristics negatively associated with children's developmental score were age, birth in a country other than France, low birth weight, and past-year hospitalization. CONCLUSIONS: There is a high prevalence of developmental delays among children growing up homeless. Public Health Implications. Long-term integrated programs improving parenting and children's opportunities for stimulation and socialization should be developed in daycare centers, schools, shelters, and medical practices to minimize negative effects of early living conditions on children's development. PMID- 29470115 TI - Older Adults' Social Relationships and Health Care Utilization: A Systematic Review. AB - BACKGROUND: Deficiencies in older people's social relationships (including loneliness, social isolation, and low social support) have been implicated as a cause of premature mortality and increased morbidity. Whether they affect service use is unclear. OBJECTIVES: To determine whether social relationships are associated with older adults' use of health services, independently of health related needs. SEARCH METHODS: We searched 8 electronic databases (MEDLINE, Embase, CINAHL, Web of Science, PsycINFO, Scopus, the Cochrane Library, and the Centre for Reviews and Dissemination) for data published between 1983 and 2016. We also identified relevant sources from scanning the reference lists of included studies and review articles, contacting authors to identify additional studies, and searching the tables of contents of key journals. SELECTION CRITERIA: Studies met inclusion criteria if more than 50% of participants were older than 60 years or mean age was older than 60 years; they included a measure of social networks, received social support, or perceived support; and they reported quantitative data on the association between social relationships and older adults' health service utilization. DATA COLLECTION AND ANALYSIS: Two researchers independently screened studies for inclusion. They extracted data and appraised study quality by using standardized forms. In a narrative synthesis, we grouped the studies according to the outcome of interest (physician visits, hospital admissions, hospital readmissions, emergency department use, hospital length of stay, utilization of home- and community-based services, contact with general health services, and mental health service use) and the domain of social relationships covered (social networks, received social support, or perceived support). For each service type and social relationship domain, we assessed the strength of the evidence across studies according to the quantity and quality of studies and consistency of findings. MAIN RESULTS: The literature search retrieved 26 077 citations, 126 of which met inclusion criteria. Data were reported across 226 678 participants from 19 countries. We identified strong evidence of an association between weaker social relationships and increased rates of readmission to hospital (75% of high-quality studies reported evidence of an association in the same direction). In evidence of moderate strength, according to 2 high-quality and 3 medium-quality studies, smaller social networks were associated with longer hospital stays. When we considered received and perceived social support separately, they were not linked to health care use. Overall, the evidence did not indicate that older patients with weaker social relationships place greater demands on ambulatory care (including physician visits and community- or home based services) than warranted by their needs. AUTHORS' CONCLUSIONS: Current evidence does not support the view that, independently of health status, older patients with lower levels of social support place greater demands on ambulatory care. Future research on social relationships would benefit from a consensus on clinically relevant concepts to measure. Public Health Implications. Our findings are important for public health because they challenge the notion that lonely older adults are a burden on all health and social care services. In high-income countries, interventions aimed at reducing social isolation and loneliness are promoted as a means of preventing inappropriate service use. Our review cautions against assuming that reductions in care utilization can be achieved by intervening to strengthen social relationships. PMID- 29470118 TI - The Inverse Equity Hypothesis: Analyses of Institutional Deliveries in 286 National Surveys. AB - OBJECTIVES: To test the inverse equity hypothesis, which postulates that new health interventions are initially adopted by the wealthy and thus increase inequalities-as population coverage increases, only the poorest will lag behind all other groups. METHODS: We analyzed the proportion of births occurring in a health facility by wealth quintile in 286 surveys from 89 low- and middle-income countries (1993-2015) and developed an inequality pattern index. Positive values indicate that inequality is driven by early adoption by the wealthy (top inequality), whereas negative values signal bottom inequality. RESULTS: Absolute inequalities were widest when national coverage was around 50%. At low national coverage levels, top inequality was evident with coverage in the wealthiest quintile taking off rapidly; at 60% or higher national coverage, bottom inequality became the predominant pattern, with the poorest quintile lagging behind. CONCLUSIONS: Policies need to be tailored to inequality patterns. When top inequalities are present, barriers that limit uptake by most of the population must be identified and addressed. When bottom inequalities exist, interventions must be targeted at specific subgroups that are left behind.

AB - OBJECTIVES: To describe a community-wide contraception initiative and assess changes in method use when cost and access barriers are removed in an environment with client-centered counseling. METHODS: HER Salt Lake is a prospective cohort study occurring during three 6-month periods (September 2015 through March 2017) and nested in a quasiexperimental observational study. The sample was women aged 16 to 45 years receiving new contraceptive services at health centers in Salt Lake County, Utah. Following the control period, intervention 1 removed cost and ensured staffing and pharmacy stocking; intervention 2 introduced targeted electronic outreach. We used logistic regression and interrupted time series regression analyses to assess impact. RESULTS: New contraceptive services were provided to 4107 clients in the control period, 3995 in intervention 1, and 3407 in intervention 2. The odds of getting an intrauterine device or implant increased 1.6 times (95% confidence interval [CI] = 1.5, 1.6) during intervention 1 and 2.5 times (95% CI = 2.2, 2.8) during intervention 2, relative to the control period. Time series analysis demonstrated that participating health centers placed an additional 59 intrauterine devices and implants on average per month (95% CI = 13, 105) after intervention 1. CONCLUSIONS: Removing client cost and increasing clinic capacity was associated with shifts in contraceptive method mix in an environment with client-centered counseling; targeted electronic outreach further augmented these results. PMID- 29470120 TI - Racial/Ethnic Variation in the Impact of the Affordable Care Act on Insurance Coverage and Access Among Young Adults. AB - OBJECTIVES: To examine the impact of the Affordable Care Act's (ACA's) 2010 parental insurance coverage extension to young adults aged 19 to 25 years on health insurance coverage and access to care, including racial/ethnic disparities. METHODS: We pooled data from the Behavioral Risk Factor Surveillance System for the periods 2007 to 2009 and 2011 to 2013 (n = 402 777). We constructed quasiexperimental difference-in-differences models in which adults aged 26 to 35 years served as a control group. Multivariable statistical models controlled for covariates guided by the Andersen model for health care utilization. RESULTS: On average, insurance rates among young adults increased 6.12 percentage points after ACA implementation (P < .001). All racial/ethnic groups experienced increases in coverage. However, the impact varied by race/ethnicity and was largest for Whites. Young adults had a 2.61 percentage point (P < .001) decrease in experiencing barriers to health care because of cost issues after the ACA, with variation by race/ethnicity. CONCLUSIONS: The ACA's expansion had a significant positive effect for young adults acquiring health insurance and reducing cost-related barriers to accessing health care. However, racial/ethnic disparities in coverage and access persist. Public Health Implications. Policies not dependent on parental insurance could further increase access and reduce disparities. PMID- 29470121 TI - Disparities in Distribution of Particulate Matter Emission Sources by Race and Poverty Status. AB - OBJECTIVES: To quantify nationwide disparities in the location of particulate matter (PM)-emitting facilities by the characteristics of the surrounding residential population and to illustrate various spatial scales at which to consider such disparities. METHODS: We assigned facilities emitting PM in the 2011 National Emissions Inventory to nearby block groups across the 2009 to 2013 American Community Survey population. We calculated the burden from these emissions for racial/ethnic groups and by poverty status. We quantified disparities nationally and for each state and county in the country. RESULTS: For PM of 2.5 micrometers in diameter or less, those in poverty had 1.35 times higher burden than did the overall population, and non-Whites had 1.28 times higher burden. Blacks, specifically, had 1.54 times higher burden than did the overall population. These patterns were relatively unaffected by sensitivity analyses, and disparities held not only nationally but within most states and counties as well. CONCLUSIONS: Disparities in burden from PM-emitting facilities exist at multiple geographic scales. Disparities for Blacks are more pronounced than are disparities on the basis of poverty status. Strictly socioeconomic considerations may be insufficient to reduce PM burdens equitably across populations. PMID- 29470122 TI - A Qualitative Comparative Analysis of Combined State Health Policies Related to Human Papillomavirus Vaccine Uptake in the United States. AB - OBJECTIVES: To examine how combinations of state policies, rather than single policies, are related to uptake of human papillomavirus (HPV) vaccine. METHODS: Using publicly available records and the literature, we characterized policies for each US state and Washington, DC, in 2015 (n = 51), including (1) Medicaid expansion, (2) policies permitting HPV vaccination in pharmacies, (3) school entry requirements, (4) classroom sex education mandates, and (5) parental education mandates. Using qualitative comparative analysis, we identified which existing combinations of these policies were necessary and sufficient for high HPV vaccine initiation among adolescents, with National Immunization Survey-Teen data. RESULTS: No single policy was necessary or sufficient for high HPV vaccine uptake; however, 1 set of policies had consistently high HPV vaccine uptake: adoption of all policies except parental education mandates (girls: consistency = 1.00, coverage = 0.07; boys: consistency = 0.99, coverage = 0.08). CONCLUSIONS: We identified a set of polices related to high HPV vaccine uptake. Future studies should examine how these policies and others, individually and in combination, are associated with HPV vaccine uptake. Public Health Implications. This study provides insight into what sets of policies are consistently related to high HPV vaccine uptake. PMID- 29470123 TI - Trends in Secondary Schools' Practices to Support Lesbian, Gay, Bisexual, Transgender, and Questioning Students, 2008-2014. AB - OBJECTIVES: To examine trends in the percentage of US secondary schools that implemented practices related to the support of lesbian, gay, bisexual, transgender, and questioning (LGBTQ) students. METHODS: This analysis used data from 4 cycles (2008-2014) of School Health Profiles, a surveillance system that provides results representative of secondary schools in each state. Each school completed 2 self-administered questionnaires (principal and teacher) per cycle. We used logistic regression models to examine linear trends. RESULTS: Of 8 examined practices to support LGBTQ youths, only 1-identifying safe spaces for LGBTQ youths-increased in most states (72%) from 2010 to 2014. Among the remaining 7, only 1-prohibiting harassment based on a student's perceived or actual sexual orientation or gender identity-had relatively high rates of adoption (a median of 90.3% of schools in 2014) across states. CONCLUSIONS: Many states have seen no change in the implementation of school practices associated with LGBTQ students' health and well-being. PMID- 29470124 TI - Storage Practices of US Gun Owners in 2016. AB - OBJECTIVES: To examine gun storage practices and factors influencing those practices among gun owners. METHODS: We conducted a nationally representative online survey of US gun owners (n = 1444) in 2016 to assess gun storage practices and attitudes, factors influencing storage practices, and groups that might effectively communicate regarding safe storage. We generated descriptive statistics by using cross-tabulations and used logistic regression to estimate characteristics that influenced safe storage practices. RESULTS: Forty-six percent of gun owners reported safely storing all of their guns. Factors associated with higher odds of reporting safe storage were having a child in the home (adjusted odds ratio [AOR] = 1.44; 95% confidence interval [CI] = 1.03, 2.03), only owning handguns (AOR = 1.84; 95% CI = 1.24, 2.73), and reporting that storage decisions were influenced by a gun safety course (AOR = 2.05; 95% CI = 1.54, 2.74) or discussions with family members (AOR = 1.39; 95% CI = 1.05, 1.86). Gun owners ranked law enforcement, hunting or outdoors groups, active-duty military, and the National Rifle Association as most effective in communicating safe storage practices. CONCLUSIONS: Public health campaigns to promote safe gun storage should consider partnering with groups that garner respect among gun owners for their experience with safe use of guns. PMID- 29470126 TI - Law Accommodating Nonmotorized Road Users and Pedestrian Fatalities in Florida, 1975 to 2013. AB - OBJECTIVES: To examine the effect of Florida's adoption of Statute 335.065-a law requiring the routine accommodation of nonmotorized road users (i.e., a "Complete Streets" policy)-on pedestrian fatalities and to identify factors influencing its implementation. METHODS: We used a multimethod design (interrupted time-series quasi-experiment and interviews) to calculate Florida's pedestrian fatality rates from 1975 to 2013-39 quarters before and 117 quarters after adoption of the law. Using statistical models, we compared Florida with regional and national comparison groups. Semistructured interviews were conducted with 10 current and former Florida transportation professionals in 2015. RESULTS: Florida's pedestrian fatality rates decreased significantly-by at least 0.500% more each quarter-after Statute 335.065 was adopted, resulting in more than 3500 lives saved across 29 years. Interviewees described supports and challenges associated with implementing the law. CONCLUSIONS: Florida Statute 335.065 is associated with a 3-decade decrease in pedestrian fatalities. The study also reveals factors that influenced the implementation and effectiveness of the law. Public Health Implications. Transportation policies-particularly Complete Streets policies-can have significant, quantifiable impacts on population health. Multimethod designs are valuable approaches to policy evaluations. PMID- 29470125 TI - Prison Health Care Governance: Guaranteeing Clinical Independence. AB - Clinical independence is an essential component of good health care and health care professionalism, particularly in correctional settings (jails, prisons, and other places of detention), where the relationship between patients and caregivers is not based on free choice and where the punitive correctional setting can challenge optimal medical care. Independence for the delivery of health care services is defined by international standards as a critical element for quality health care in correctional settings, yet many correctional facilities do not meet these standards because of a lack of awareness, persisting legal regulations, contradictory terms of employment for health professionals, or current health care governance structures. We present recommendations for the implementation of independent health care in correctional settings. PMID- 29470127 TI - Telemedicine Physical Examination Utilizing a Consumer Device Demonstrates Poor Concordance with In-Person Physical Examination in Emergency Department Patients with Sore Throat: A Prospective Blinded Study. AB - BACKGROUND: Telemedicine allows patients to connect with healthcare providers remotely. It has recently expanded to evaluate low-acuity illnesses such as pharyngitis by using patients' personal communication devices. The purpose of our study was to compare the telemedicine-facilitated physical examination with an in person examination in emergency department (ED) patients with sore throat. MATERIALS AND METHODS: This was a prospective, observational, blinded diagnostic concordance study of patients being seen for sore throat in a 60,000-visit Midwestern academic ED. A telemedicine and a face-to-face examination were performed independently by two advanced practice providers (APP), blinded to the results of the other evaluator. The primary outcome was agreement on pharyngeal redness between the evaluators, with secondary outcomes of agreement and inter rater reliability on 14 other aspects of the pharyngeal physical examination. We also conducted a survey of patients and providers to evaluate perceptions and preferences for sore throat evaluation using telemedicine. RESULTS: Sixty-two patients were enrolled, with a median tonsil size of 1.0. Inter-rater agreement (kappa) for tonsil size was 0.394, which was worse than our predetermined concordance threshold. Other kappa values ranged from 0 to 0.434, and telemedicine was best for detecting abnormal coloration of the palate and tender superficial cervical lymph nodes (anterior structures), but poor for detecting abnormal submandibular lymph nodes or asymmetry of the posterior pharynx (posterior structures). In survey responses, telemedicine was judged easier to use and more comfortable for providers than patients; however, neither patients nor providers preferred in-person to telemedicine evaluation. CONCLUSION: Telemedicine exhibited poor agreement with the in-person physical examination on the primary outcome of tonsil size, but exhibited moderate agreement on coloration of the palate and cervical lymphadenopathy. Future work should better characterize the importance of the physical examination in treatment decisions for patients with sore throat and the use of telemedicine in avoiding in-person healthcare visits. PMID- 29470128 TI - Human Subcutaneous Tissue Response to Glucose Sensors: Macrophages Accumulation Impact on Sensor Accuracy. AB - BACKGROUND: Subcutaneous (s.c.) glucose sensors have become a key component in type 1 diabetes management. However, their usability is limited by the impact of foreign body response (FBR) on their duration, reliability, and accuracy. Our study gives the first description of human acute and subacute s.c. response to glucose sensors, showing the changes observed in the sensor surface, the inflammatory cells involved in the FBR and their relationship with sensor performance. METHODS: Twelve obese patients (seven type 2 diabetes) underwent two abdominal biopsies comprising the surrounding area where they had worn two glucose sensors: the first one inserted 7 days before and the second one 24 h before biopsy procedure. Samples were processed and studied to describe tissue changes by two independent pathologists (blind regarding sensor duration). Macrophages quantification was studied by immunohistochemistry methods in the area surrounding the sensor (CD68, CD163). Sensor surface changes were studied by scanning electron microscopy. Seven-day continuous glucose monitoring records were considered inaccurate when mean absolute relative difference was higher than 10%. RESULTS: Pathologists were able to correctly classify all the biopsies regarding sensor duration. Acute response (24 h) was characterized by the presence of neutrophils while macrophages were the main cell involved in subacute inflammation. The number of macrophages around the insertion hole was higher for less accurate sensors compared with those performing more accurately (32.6 +/- 14 vs. 10.6 +/- 1 cells/0.01 mm2; P < 0.05). CONCLUSION: The accumulation of macrophages at the sensor-tissue interface is related with decrease in accuracy of the glucose measure.

AB - The number of diabetic patients worldwide is increasing, and complications such as stroke and cardiovascular disease are becoming a serious cause of death. Diabetes mellitus is classified into two types according to the etiopathogenic mechanism and insulin dependence. Type 1 diabetes (T1D), an insulin-dependent diabetes mellitus, is caused by damage and destruction of pancreatic beta cells that produce insulin. It is a disease that is characterized by hyperglycemia and hypoinsulinemia. Aronia berry has been used as a medicinal food in Europe. Aronia contains a variety of ingredients such as polyphenols, anthocyanins, flavonoids, and tannins. Especially, anthocyanin content in aronia berry is known to be much higher than in other plants and berries. It is known for exerting antioxidant, anti-inflammation, and anti-aging effects. Therefore, this study was conducted to investigate the effects of aronia berry extract intake in multiple low-dose streptozotocin (STZ)-induced T1D and to confirm the functional properties of aronia berry. ICR mice (6-week male) were divided into four groups: control (normal control group), STZ (100 mg/kg of STZ-induced T1D group), AR 10 (STZ with oral administration of aronia 10 mg/kg), and AR 100 (STZ with oral administration of aronia 100 mg/kg). Afterward, STZ was injected in a single dose to induce T1D, and the extract was orally administered daily. Dietary intake and body weight were measured twice a week. We confirmed that aronia berry has the effect of decreasing the increase of blood glucose level and also has the protection effect of pancreas beta cell (RINm5F cell). This study confirms the anti-diabetic activity of aronia berry, and it can be expected to increase the utilization according to the results. PMID- 29470135 TI - Effects of Task Difficulty and Display Format on Automation Usage Strategy: A Workload Capacity Analysis. AB - Objective An experiment used workload capacity analysis to quantify automation usage strategy across different task difficulty and display format types in a speeded task. Background Workload capacity measures the efficiency of concurrent information processing and can serve as a gauge of automation usage strategy in speeded decision tasks. The present study used workload capacity analysis to investigate automation usage strategy while information display format and task difficulty were manipulated. Method Subjects performed a speeded judgment task assisted by an automated aid that issued decision cues at varying onset times. Response time distributions were converted to measures of workload capacity. Results Two variants of a workload capacity measure, CzOR and CzAND, gave evidence that operators moderated their own decision times both in anticipation of and following the arrival of the aid's diagnosis under difficult task conditions regardless of display format. Conclusion Assistance from an automated decision aid may cause operators to delay their own responses in a speeded decision task, producing joint response time distributions that are slower than optimal. Application Even when it renders its own judgments quickly and with high accuracy, an automated decision aid may slow responses from a user. Automation designers should consider the relative costs and benefits of response accuracy and time when choosing whether and how to implement an automated decision aid. PMID- 29470137 TI - Open Access: Is There a Predator at the Door? PMID- 29470136 TI - 15O-H2O PET/CT as a tool for the quantitative assessment of early post radiotherapy changes of heart perfusion in breast carcinoma patients. AB - OBJECTIVE: Studies examining radiation-induced heart toxicity in breast cancer patients are inconclusive. The aim of this study was to prospectively and quantitatively asses myocardial blood flow (MBF) with, for the first time, 15O H2O PET/CT as a marker of heart damage in irradiated breast cancer patients. METHODS: 15 breast cancer patients receiving intact breast or chest wall irradiation were included in the analysis (six with right-sided and nine with left-sided breast cancer). They underwent 15O-H2O PET/CT before radiotherapy (RT) and 2 and 8 months after RT. MBF was quantitatively assessed at rest and under stress conditions in 17 heart segments distinguished according to the American Ultrasound Association classification. Regional MBF values were derived in each of the coronary artery territories. RESULTS: MBF decreased in 53% and increased in 33% of cases 2 months after RT in both left-sided and right-sided breast cancer patients. Stress testing was more sensitive than at-rest testing, demonstrating decreased perfusion in the segments supplied by the left anterior descending coronary artery (LAD) [5.41 +/- 1.74 vs 4.52 +/- 1.82 ml (g*min)-1; p = 0.018], which persisted at 6 months [5.41 +/- 1.74 vs 4.40 +/- 1.38 ml (g*min) 1; p = 0.032] and a decrease in global heart perfusion [5.14 +/- 1.49 vs 4.46 +/- 1.73 ml (g*min)-1; p = 0.036]. A minimal radiation dose applied to the LAD correlated with MBF changes observed 2 months after RT (r = -0.57; p = 0.032). Radiological findings were not correlated with clinical symptoms of heart toxicity. CONCLUSION: 15O-H2O PET/CT is safe and effective for the early detection and quantitative analysis of subclinical post-RT changes in heart perfusion in breast cancer patients. The LV segments supplied by the LAD are the main site of MBF changes. A minimum radiation dose deposited in the LAD may be a predictor of radiation-induced heart toxicity. Advances in knowledge: This is the first time that 15O-H2O PET/CT has been used to assess MBF after RT and the first granular description of the distribution of blood flow changes after breast cancer RT. PMID- 29470138 TI - Tracking Nemo: Help Scientists Understand Zebrafish Behavior. AB - The advent of automated tracking software has significantly reduced the time required to record movement trajectories, thereby facilitating behavioral studies of zebrafish. However, results are substantially influenced by tracking errors, such as loss and misidentification of individuals. In this study, we present the development of an online citizen science platform, Tracking Nemo, to improve data accuracy on swimming trajectories of zebrafish groups. As an online extension of software for tracking the position of zebrafish from video recordings, Tracking Nemo offers volunteers the opportunity to contribute to science by manually correcting tracked trajectory data from their personal computers. Researchers can upload their videos that require human intervention for correcting and validating the data. Citizen scientists can monitor their contributions through a leaderboard system, which is designed to strengthen participant retention and contribution by tapping into intrinsic and extrinsic motivations. Tracking Nemo is expected to help scientists improve data accuracy through the involvement of citizen scientists, who, in turn, engage in an authentic research activity and learn more about the behavior of zebrafish. PMID- 29470139 TI - Microstructural investigation of masticatory muscles: a pre- and post-treatment diffusion tensor imaging study in a bruxism case. AB - We evaluated, by means of a non-invasive procedure based on MRI, the masticatory muscular microstructure in a 55-year-old-female patient affected by bruxism. The patient underwent MR examination before and after 1 month of splint therapy, when she mentioned the complete disappearance of all symptoms. By means of diffusion tensor imaging we observed changes at microstructural level of masticatory muscular complex. We conclude that diffusion tensor imaging may be a useful instrument both to perform panoramic reconstruction of the masticatory muscle complex and to investigate microstructural modifications related to the pain relief in bruxism. PMID- 29470140 TI - Simple and fast spectrophotometric determination of low levels of thiabendazole residues in fruit and vegetables after pre-concentration with ionic liquid phase microextraction. AB - There is a great importance of monitoring thiabendazole (TBZ) residues in fruits and vegetables to ensure food safety. Therefore, a new ionic liquid (IL) phase microextraction method using IL, 1-butyl-3-methylimidazoliumhexafluorophosphate [C4mim][PF6], as extracting solvent is proposed for simple and fast determination of low levels of TBZ in fruits and vegetables by spectrophotometry. The method is based on selective complex formation of TBZ with Cu(II) ions in presence of PF6- as counter ion at pH 5.5, and then microextraction of the complex into the fine micro-drops of IL phase. After optimisation of variables affecting microextraction efficiency, the analytical parameters of the method were determined by calibration curves. The method exhibits a linear relationship (0.3 280 MUg L-1), low detection limit (0.1 MUg L-1), good intra- and inter-day precision (2.4-4.5% as RSDr%, 2.1-5.6% as RSDR%), good recovery (>=95.1-98.2%) and high sensitivity enhancement factor (150) by solvent-based calibration curve. It allows a detection limit of 0.24 MUg L-1 and a range of 0.8-250 MUg L-1 by the matrix-matched calibration curve. After validation, the method was successfully applied to the determination of TBZ residues with method quantification limits in fruit and vegetables of 2.0 and 2.5 ug kg-1 with and without adding polyvinylpyrrolidone (PVP-15) solution. Recoveries range from 85.5% to 98.2% after spiking (10, 50 and 100 ug kg-1, n: 3). PMID- 29470141 TI - Denial's Many Faces.

AB - Purpose Phosphatidylinositol-4, 5-bisphosphate 3-kinase catalytic subunit alpha ( PIK3CA) mutations are frequently observed in primary breast cancer. We evaluated their prognostic relevance by performing a pooled analysis of individual patient data. Patients and Methods Associations between PIK3CA status and clinicopathologic characteristics were tested by applying Cox regression models adjusted for age, tumor size, nodes, grade, estrogen receptor (ER) status, human epidermal growth factor receptor 2 (HER2) status, treatment, and study. Invasive disease-free survival (IDFS) was the primary end point; distant disease-free survival (DDFS) and overall survival (OS) were also assessed, overall and by breast cancer subtypes. Results Data from 10,319 patients from 19 studies were included (median OS follow-up, 6.9 years); 1,787 patients (17%) received chemotherapy, 4,036 (39%) received endocrine monotherapy, 3,583 (35%) received both, and 913 (9%) received none or their treatment was unknown. PIK3CA mutations occurred in 32% of patients, with significant associations with ER positivity, increasing age, lower grade, and smaller size (all P < .001). Prevalence of PIK3CA mutations was 18%, 22%, and 37% in the ER-negative/HER2-negative, HER2 positive, and ER-positive/HER2-negative subtypes, respectively. In univariable analysis, PIK3CA mutations were associated with better IDFS (HR, 0.77; 95% CI, 0.71 to 0.84; P < .001), with evidence for a stronger effect in the first years of follow-up (0 to 5 years: HR, 0.73; 95% CI, 0.66 to 0.81; P < .001; 5 to 10 years: HR, 0.82; 95% CI, 0.68 to 0.99; P = .037); > 10 years: (HR, 1.15; 95% CI, 0.84 to 1.58; P = .38; P heterogeneity = .02). In multivariable analysis, PIK3CA genotype remained significant for improved IDFS ( P = .043), but not for the DDFS and OS end points. Conclusion In this large pooled analysis, PIK3CA mutations were significantly associated with a better IDFS, DDFS, and OS, but had a lesser prognostic effect after adjustment for other prognostic factors. PMID- 29470144 TI - Effect of mono- and diglycerides on the digestion and absorption of lutein in lymph fistula rats. AB - Breast milk lutein is better absorbed by infants than lutein delivered in infant formula. Therefore, we wanted to better understand the possible absorption differences of lutein in breast milk vs. that in infant formula by determining its bioavailability after gastric administration and whether the intestinal absorption of lutein can be improved by using new delivery vehicles. Study 1 compared the intestinal uptake,and the lymphatic and portal transport of lutein in conscious lymph fistula rats. Four groups of lymph- and portal vein-cannulated rats ( n = 8-10/group) were randomized to receive via gastric tube increasing doses (10, 20, 40, or 80 mg/kg) of 20% lutein in safflower oil (SO) suspension to assess whether there was a saturable level of lutein that could be absorbed and transported in lymph. Aliquots of hourly portal blood and lymph were taken for lutein and zeaxanthin analyses. The dose-response study showed that 20 mg/kg lutein was the saturable level of lymphatic lutein absorption with no lutein detected in portal circulation at any dosage level tested. Study 2 randomized five groups of lymph fistula rats ( n = 4-9/group) to receive 20 mg/kg lutein from either lutein in SO or lutein in four different mono- and diglyceride oils (MDGs). Gastric infusion of lutein suspended in MDG (20 mg/kg) significantly improved (71-211%, P < 0.05) lymphatic lutein output 2-6 h after lipid feeding vs. lutein in SO. Lymphatic zeaxanthin (10% of the lutein fed mixture) transport in both Study 1 and Study 2 followed that of lutein. We conclude that a mixture of MDGs helps solubilize lutein and facilitate gastrointestinal micelle formation, thus improving lymphatic lutein absorption compared with triglyceride oils. NEW & NOTEWORTHY This paper describes how lutein is digested and absorbed by the gastrointestinal tract by using the conscious lymph fistula rat model. Our dose-response study showed that absorption and lymphatic transport of lutein is a saturable process with no lutein detected in portal circulation at any dosage level tested. Our paper also provides insight into how this process can be improved by modifying the typical lipid mixtures carrying the lutein. PMID- 29470145 TI - Portal vein stenosis preconditioning of living donor liver in swine: early mechanisms of liver regeneration and gain of hepatic functional mass. AB - To reduce the morbidity and mortality risk for the donor in living donor liver transplantation (LDLT), we previously identified 20% left portal vein (LPV) stenosis as an effective preconditioning method to induce cell proliferation in the contralateral lobe without downstream ipsilateral atrophy. In this study, we report the pathways involved in the first hours after preconditioning and investigate the changes in liver volume and function. Fourteen pigs were used this study. Five pigs were used to study the genetic, cellular and molecular mechanisms set up in the early hours following the establishment of our preconditioning. The remaining nine pigs were equally divided into three groups: sham-operated animals, 20% LPV stenosis, and 100% LPV stenosis. Volumetric scanning and 99 mTc-Mebrofenin hepatobiliary scintigraphy were performed before preconditioning and 14 days after to study morphological and functional changes in the liver. We demonstrated that liver regeneration triggered by 20% LPV stenosis in the contralateral lobe involves TNF-alpha, IL-6, and inducible nitric oxide synthase 2 by means of STAT3 and hepatocyte growth factor. We confirmed that our preconditioning was responsible for an increase in the total liver volume. Finally, we demonstrated that this volumetric gain was associated with an increase in hepatic functional capacity. NEW & NOTEWORTHY We describe a new preconditioning method for major hepatectomy that is applicable to hepatectomy for donation. We identified 20% left portal vein stenosis as effective preconditioning that is capable of inducing cell proliferation in the contralateral lobe without the downstream ipsilateral atrophy. In this study, we report the pathways involved in the first hours following preconditioning, and we confirm that 20% left portal vein stenosis is responsible for an increase in the functional capacity and total liver volume in a porcine model. PMID- 29470146 TI - Toward an effective peripheral visceral analgesic: responding to the national opioid crisis. AB - This minireiew summarizes recent new developments in visceral analgesics. This promising field is important, as a new approach to address abdominal pain with peripheral visceral analgesics is considered a key approach to addressing the current opioid crisis. Some of the novel compounds address peripheral pain mechanisms through modulation of opioid receptors via biased ligands, nociceptin/orphanin FQ opioid peptide (NOP) receptor, or dual action on NOP and MU-opioid receptor, buprenorphine and morphiceptin analogs. Other compounds target nonopioid mechanisms, including cannabinoid (CB2), N-methyl-d-aspartate, calcitonin gene-related peptide, estrogen, and adenosine A2B receptors and transient receptor potential (TRP) channels (TRPV1, TRPV4, and TRPM8). Although current evidence is based predominantly on animal models of visceral pain, early human studies also support the evidence from the basic and animal research. This augurs well for the development of nonaddictive, visceral analgesics for treatment of chronic abdominal pain, an unmet clinical need. PMID- 29470147 TI - Repeated airway constrictions in mice do not alter respiratory function. AB - It is suggested that the frequent strain the airways undergo in asthma because of repeated airway smooth muscle (ASM)-mediated constrictions contributes to airway wall remodeling. However, the effects of repeated constrictions on airway remodeling, as well as the ensuing impact of this presumptive remodeling on respiratory mechanics, have never been investigated in subjects without asthma. In this study, we set out to determine whether repeated constrictions lead to features that are reminiscent of asthma in mice without asthma. BALB/c mice were subjected to a 30-min constriction elicited by aerosolized methacholine every other day over 6 wk. Forty-eight hours after the last constriction, the mechanics of the respiratory system was evaluated at baseline and in response to incremental doses of nebulized methacholine with the flexiVent. The whole-lung lavages, the tracheas, and the lungs were also collected to evaluate inflammation, the contractile capacity of ASM, and the structural components of the airway wall, respectively. The resistance and the compliance of the respiratory system, as well as the Newtonian resistance and the resistive and elastic properties of the lung tissue, were not affected by repeated constrictions, both at baseline and in response to methacholine. All the other examined features also remained unaltered, except the number of goblet cells in the epithelium and the number of macrophages in the whole-lung lavages, which both increased with repeated constrictions. This study demonstrates that, despite causing goblet cell hyperplasia and a mild macrophagic inflammation, repeated constrictions with methacholine do not lead to structural changes that adversely impact the physiology. NEW & NOTEWORTHY Repeated airway constrictions led to signs of remodeling that are typically observed in asthma, which neither altered respiratory mechanics nor the contractile capacity of airway smooth muscle. These findings shed light on a debate between those claiming that constrictions induce remodeling and those convinced that methacholine challenges are harmless. Insofar as our results with mice relate to humans, the findings indicate that repeated challenges with methacholine can be performed safely. PMID- 29470148 TI - Voluntary wheel running increases satellite cell abundance and improves recovery from disuse in gastrocnemius muscles from mice. AB - Reloading of atrophied muscles after hindlimb suspension unloading (HSU) can induce injury and prolong recovery. Low-impact exercise, such as voluntary wheel running, has been identified as a nondamaging rehabilitation therapy in rodents, but its effects on muscle function, morphology, and satellite cell activity after HSU are unclear. This study tested the hypothesis that low-impact wheel running would increase satellite cell proliferation and improve recovery of muscle structure and function after HSU in mice. Young adult male and female C57BL/6 mice ( n = 6/group) were randomly placed into five groups. These included HSU without recovery (HSU), normal ambulatory recovery for 14 days after HSU (HSU+NoWR), and voluntary wheel running recovery for 14 days after HSU (HSU+WR). Two control groups were used: nonsuspended mouse cage controls (Control) and voluntary wheel running controls (ControlWR). Satellite cell activation was evaluated by providing mice 5-bromo-2'-deoxyuridine (BrdU) in their drinking water. As expected, HSU significantly reduced in vivo maximal force, decreased in vivo fatigability, and decreased type I and IIa myosin heavy chain (MHC) abundance in plantarflexor muscles. HSU+WR mice significantly improved plantarflexor fatigue resistance, increased type I and IIa MHC abundance, increased fiber cross-sectional area, and increased the percentage of type I and IIA muscle fibers in the gastrocnemius muscle. HSU+WR mice also had a significantly greater percentage of BrdU-positive and Pax 7-positive nuclei inside muscle fibers and a greater MyoD-to-Pax 7 protein ratio compared with HSU+NoWR mice. The mechanotransduction protein Yes-associated protein (YAP) was elevated with reloading after HSU, but HSU+WR mice had lower levels of the inactive phosphorylated YAPserine127, which may have contributed to increased satellite cell activation with reloading after HSU. These results indicate that voluntary wheel running increased YAP signaling and satellite cell activity after HSU and this was associated with improved recovery. NEW & NOTEWORTHY Although satellite cell involvement in muscle remodeling has been challenged, the data in this study suggest that voluntary wheel running increased satellite cell activity and suppressed Yes-associated protein (YAP) protein relative to no wheel running and this was associated with improved muscle recovery of force, fatigue resistance, expression of type I myosin heavy chain, and greater fiber cross sectional area after disuse. PMID- 29470150 TI - Metrics of lung tissue heterogeneity depend on BMI but not age. AB - Altered parenchymal microstructure and complexity have been observed in older age. How to distinguish between healthy, expected changes and early signs of pathology remains poorly understood. An objective quantitative analysis of computed tomography imaging was conducted to compare mean lung density, tissue density distributions, and tissue heterogeneity in 16 subjects, 8 aged >60 yr who were gender and body mass index matched with 8 subjects aged <30 yr. Subjects had never been smokers, with no prior respiratory disease, and no radiologically identified abnormalities on computed tomography. Volume-controlled breath hold imaging acquired at 80% vital capacity (end inspiration) and 55% vital capacity (end expiration) were used for analysis. Mean lung density was not different between the age groups at end inspiration ( P = 0.806) but was larger in the younger group at end expiration (0.26 +/- 0.033 vs. 0.22 +/- 0.026, P = 0.008), as is expected due to increased air trapping in the older population. However, gravitational gradients of tissue density did not differ with age; the only difference in distribution of tissue density between the two age groups was a lower density in the apices of the older group at end expiration. The heterogeneity of the lung tissue assessed using two metrics showed significant differences between end inspiration and end expiration, no dependence on age, and a significant relationship with body mass index at both lung volumes when heterogeneity was calculated using quadtree decomposition but only at end expiration when using a fractal dimension. NEW & NOTEWORTHY Changes to lung tissue heterogeneity can be a normal part of aging but can also be an early indicator of disease. We use novel techniques, which have previously not been used on thoracic computed tomography imaging, to quantify lung tissue heterogeneity in young and old healthy subjects. Our results show no dependence on age but a significant correlation with body mass index. PMID- 29470149 TI - Chronic, complete cervical6-7 cord transection: distinct autonomic and cardiac deficits. AB - Spinal cord injury (SCI) resulting in tetraplegia is a devastating, life-changing insult causing paralysis and sensory impairment as well as distinct autonomic dysfunction that triggers compromised cardiovascular, bowel, bladder, and sexual activity. Life becomes a battle for independence as even routine bodily functions and the smallest activity of daily living become major challenges. Accordingly, there is a critical need for a chronic preclinical model of tetraplegia. This report addresses this critical need by comparing, for the first time, resting-, reflex-, and stress-induced cardiovascular, autonomic, and hormonal responses each week for 4 wk in 12 sham-operated intact rats and 12 rats with chronic, complete C6-7 spinal cord transection. Loss of supraspinal control to all sympathetic preganglionic neurons projecting to the heart and vasculature resulted in a profound bradycardia and hypotension, reduced cardiac sympathetic and parasympathetic tonus, reduced reflex- and stress-induced sympathetic responses, and reduced sympathetic support of blood pressure as well as enhanced reliance on angiotensin to maintain arterial blood pressure. Histological examination of the nucleus ambiguus and stellate ganglia supports the profound and distinct autonomic and cardiac deficits and reliance on angiotensin to maintain cardiovascular stability following chronic, complete cervical6-7 cord transection. NEW & NOTEWORTHY For the first time, resting-, reflex-, and stress induced cardiovascular, autonomic, and hormonal responses were studied in rats with chronic, complete C6-7 cord transection. Loss of supraspinal control of all sympathetic preganglionic neurons reduced cardiac sympathetic and parasympathetic tonus, reflex and stress-induced sympathetic responses, and sympathetic support of blood pressure as well as enhanced reliance on angiotensin to maintain arterial blood pressure. Histological examination supports the distinct deficits associated with cervical cord injury. PMID- 29470151 TI - Caffeine increases both total work performed above critical power and peripheral fatigue during a 4-km cycling time trial. AB - The link between total work performed above critical power (CP) and peripheral muscle fatigue during self-paced exercise is unknown. We investigated the influence of caffeine on the total work done above CP during a 4-km cycling time trial (TT) and the subsequent consequence on the development of central and peripheral fatigue. Nine cyclists performed three constant-load exercise trials to determine CP and two 4-km TTs ~75 min after oral caffeine (5 mg/kg) or cellulose (placebo) ingestion. Neuromuscular functions were assessed before and 50 min after supplementation and 1 min after TT. Oral supplementation alone had no effect on neuromuscular function ( P > 0.05). Compared with placebo, caffeine increased mean power output (~4%, P = 0.01) and muscle recruitment (as inferred by EMG, ~17%, P = 0.01) and reduced the time to complete the TT (~2%, P = 0.01). Work performed above CP during the caffeine trial (16.7 +/- 2.1 kJ) was significantly higher than during the placebo (14.7 +/- 2.1 kJ, P = 0.01). End exercise decline in quadriceps twitch force (pre- to postexercise decrease in twitch force at 1 and 10 Hz) was more pronounced after caffeine compared with placebo (121 +/- 13 and 137 +/- 14 N vs. 146 +/- 13 and 156 +/- 11 N; P < 0.05). There was no effect of caffeine on central fatigue. In conclusion, caffeine increases muscle recruitment, which enables greater work performed above CP and higher end-exercise peripheral locomotor muscle fatigue. NEW & NOTEWORTHY The link between total work done above critical power and peripheral fatigue during a self-paced, high-intensity exercise is unclear. This study revealed that caffeine ingestion increases muscle recruitment, which enables greater work done above critical power and a greater degree of end-exercise decline in quadriceps twitch force during a 4-km cycling time trial. These findings suggest that caffeine increases performance at the expense of greater locomotor muscle fatigue. PMID- 29470152 TI - Linalyl acetate restores endothelial dysfunction and hemodynamic alterations in diabetic rats exposed to chronic immobilization stress. AB - Although stress is one of the risk factors of diabetes, few studies have assessed the effects of stress on diabetic rats. This study, therefore, analyzed differences in cardiovascular-related factors among control, nonstressed diabetic, and stressed diabetic rats as well as assessed the effects of linalyl acetate (LA) on stressed diabetic rats. Male Sprague-Dawley rats were subjected to immobilization stress throughout the experimental period, and diabetes was induced on day 15 by a single injection of streptozotocin. After confirming the induction of diabetes, stressed diabetic rats were administered LA (10 or 100 mg/kg) or metformin (500 mg/kg) for the last 7 days. Compared with nonstressed diabetic rats, stressed diabetic rats had significantly lower body weight, body fat percentage, ACh-induced vasorelaxation, systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), and NF-kappaB expression as well as increased serum nitrite concentration. Although metformin increased serum insulin concentration significantly, 100 mg/kg LA showed only an increasing tendency. However, treatment with 100 mg/kg LA not only reduced serum glucose and NF-kappaB expression, but also restored ACh-induced vasorelaxation, SBP, DBP, HR, AMP-activated protein kinase expression, and serum nitrite almost to control levels. Importantly, 100 mg/kg LA was more effective than metformin in ameliorating serum glucose, endothelial nitric oxide synthase expression, HR, and serum nitrite. These findings suggest that chronic stress can aggravate endothelial dysfunction and hemodynamic alterations in diabetes and that LA may have potent therapeutic efficacy in diabetic patients with cardiovascular disease complications or chronic stress. NEW & NOTEWORTHY To our knowledge, this is the first study to assess the effects of linalyl acetate (LA) on cardiovascular related factors in diabetic rats exposed to chronic stress. Treatment with LA restored acetylcholine-induced vasorelaxation, blood pressure, heart rate, and AMP-activated protein kinase and serum nitrite levels. The present results suggest that LA may have potent therapeutic efficacy in diabetic patients with complications of cardiovascular disease or chronic stress. PMID- 29470153 TI - Structured Reporting of Multiphasic CT for Hepatocellular Carcinoma: Effect on Staging and Suitability for Transplant. AB - OBJECTIVE: The purpose of this study is to evaluate whether use of a standardized radiology report template would improve the ability of liver transplant surgeons to diagnose stage T2 hepatocellular carcinoma (HCC) and determine patient suitability to undergo orthotopic liver transplant (OLT). MATERIALS AND METHODS: In this retrospective study, a standardized template was devised, and its use was mandated for reporting of liver CT findings for patients with cirrhosis and HCC. Two surgeons analyzed 200 reports (100 before and 100 after template implementation) for descriptions of cirrhosis, portal hypertension, lesion enhancement characteristics, tumor thrombus, portal and superior mesenteric vein patency, and Organ Procurement Transplantation Network (OPTN) class. Ability to determine Milan criteria and surgeon satisfaction were also assessed. Data obtained before and after template implementation were statistically analyzed using the Cochran-Mantel-Haenszel test. RESULTS: Template implementation increased the percentage of reports documenting the presence or absence of portal hypertension (74% to 88% for surgeon 1 and 86% to 87% for surgeon 2; p = 0.042); lesion number (76% to 88% for surgeon 2 [no change for surgeon 1]; p = 0.038), size (95% to 96% for surgeon 1 and 82% to 93% for surgeon 2; p = 0.03), and enhancement (93% to 94% for surgeon 1 and 80% to 91% for surgeon 2; p = 0.049); presence of tumor thrombus (10% to 57% for surgeon 1 and 31% to 63% for surgeon 2; p < 0.001); and OPTN class (8% to 82% for surgeon 1 and 2% to 81% for surgeon 2; p < 0.001). The surgeons were significantly more able to determine the presence of T2 disease and qualification for exception points after implementation of the template (increasing from 80% to 94%; p = 0.025). Satisfaction with reports also improved (p < 0.0001). CONCLUSION: The reporting template improved determination of patient suitability to undergo transplant according to the Milan criteria. PMID- 29470154 TI - Unipedal Diagnostic Lymphangiography Followed by Sequential CT Examinations in Patients With Idiopathic Chyluria: A Retrospective Study. AB - OBJECTIVE: The objective of our study was to investigate the clinical value of diagnostic lymphangiography followed by sequential CT examinations in patients with idiopathic chyluria. MATERIALS AND METHODS: Thirty-six patients with idiopathic chyluria underwent unipedal diagnostic lymphangiography and then underwent sequential CT examinations. The examinations were reviewed separately by two radiologists. Abnormal distribution of contrast medium, lymphourinary leakages, and retrograde flow were noted, and the range and distribution of lymphatic vessel lesions were recorded. The stage of idiopathic chyluria based on CT findings and the stage based on clinical findings were compared. Therapeutic management and follow-up were recorded. Statistical analyses were performed. RESULTS: Compared with CT studies performed after lymphangiography, diagnostic lymphangiography showed a unique capability to depict lymphourinary leakages in three patients. Lymphourinary fistulas and abnormal dilated lymphatic vessels were found in and around kidney in all patients. CT depicted retrograde flow of lymph fluid in 47.2% of patients. The consistency in staging chyluria based on CT findings and clinical findings was fair (kappa = 0.455). Twenty-nine patients underwent conservative therapy, and seven underwent surgery. Surgical therapy was superior to conservative management (no recurrence, 85.7% of patients who underwent surgery vs 62.1% of patients who underwent conservative therapy; p = 0.025). CONCLUSION: From assessing the drainage of contrast medium on unipedal diagnostic lymphangiography and the redistribution of contrast medium on sequential CT examinations, it is possible to detect the existence of lymphourinary fistulas, the precise location of lymphatic anomalies, the distribution of collateral lymphatic vessels, and hydrodynamic pressure abnormality in the lymph circulation in patients with idiopathic chyluria. CT staging of chyluria provides additional information that can be used to guide therapeutic management. PMID- 29470155 TI - Clinical Utility of Dual-Energy CT Analysis of Bone Marrow Edema in Acute Wrist Fractures. AB - OBJECTIVE: The purpose of this study is to determine the utility of dual-energy CT (DECT) for assessing carpal fractures and to obtain an attenuation value cutoff (in Hounsfield units) to identify bone marrow edema due to an acute carpal fracture. MATERIALS AND METHODS: In this retrospective study, 24 patients who presented with wrist fractures from September 3, 2014, through March 9, 2015, underwent imaging with DECT (80 and 140 kVp). Using the three-material decomposition algorithm specific for virtual noncalcium to construct images, two radiologists identified carpal fractures and associated bone marrow edema. Readers noted the attenuation at areas with and without bone marrow edema. The cutoff value was obtained by ROC analysis and was internally validated on 13 separate patients with suspected wrist fractures. A p < 0.05 was considered statistically significant. RESULTS: CT attenuation was significantly higher in areas of bone marrow edema than in areas without it (p < 0.0001, t test). A cutoff of 5.90 HU allows detection of bone marrow edema associated with acute wrist fractures with 100% sensitivity and 99.5% specificity, compared with visual DECT interpretation. In the 13 validation cases, the cutoff of 5.90 HU identified bone marrow edema with 100% accuracy, compared with visual interpretation. Kappa values were 0.83 between the two readings by reader 1, and 0.73 and 0.96 comparing the two readings of reader 1 with the reading by reader 2. CONCLUSION: DECT is a useful tool for identifying bone marrow edema in the setting of acute wrist fractures, providing an alternative to MRI. A cutoff value of 5.90 HU can be used for accurate diagnosis and exclusion of carpal fractures. PMID- 29470156 TI - JOURNAL CLUB: Evaluation of Diffusion Kurtosis Imaging of Stroke Lesion With Hemodynamic and Metabolic MRI in a Rodent Model of Acute Stroke. AB - OBJECTIVE: Diffusion kurtosis imaging (DKI) has emerged as a new acute stroke imaging approach, augmenting routine DWI. Although it has been shown that a diffusion lesion without kurtosis abnormality is more likely to recover after reperfusion, whereas a kurtosis lesion shows poor response, little is known about the underlying pathophysiologic profile of the kurtosis lesion versus the kurtosis lesion-diffusion lesion mismatch. MATERIALS AND METHODS: We performed multiparametric MRI, including arterial spin labeling, pH-sensitive amide proton transfer, and DKI, in a rodent model of acute stroke caused by embolic middle cerebral artery occlusion. Diffusion and kurtosis lesions were semiautomatically segmented, and multiparametric MRI indexes were compared among the kurtosis lesion, diffusion lesion, kurtosis lesion-diffusion lesion mismatch, and the contralateral normal tissue area. RESULTS: We confirmed a significant difference between diffusion lesion and kurtosis lesion volumes (mean [+/- SD] volume, 151 +/- 65 vs 125 +/- 47 mm3; p < 0.05). Although ischemic lesions have significantly reduced cerebral blood flow compared with contralateral normal tissue, we did not find a significant difference in cerebral blood flow between the kurtosis lesion and the kurtosis lesion-diffusion lesion mismatch (mean cerebral blood flow, 0.53 +/- 0.10 vs 0.47 +/- 0.14 mL/g of tissue per minute; p > 0.05). Of importance, the pH of the kurtosis lesion was significantly lower than that of the lesion mismatch (mean pH, 6.81 +/- 0.08 vs 6.89 +/- 0.09; p < 0.01). CONCLUSION: The present study confirms that DKI provides an expedient approach for refining the heterogeneous DWI lesion that is associated with graded metabolic derangement, which is promising for improving the infarction core definition and ultimately helping to guide stroke treatment. PMID- 29470157 TI - Solid Small Renal Mass Without Gross Fat: CT Criteria for Achieving Excellent Positive Predictive Value for Renal Cell Carcinoma. AB - OBJECTIVE: The purpose of this study was to evaluate CT criteria for achieving high positive predictive value (PPV) for renal cell carcinoma (RCC) in patients with solid small renal masses (SRMs) less than 4 cm without macroscopic fat. MATERIALS AND METHODS: One hundred fifty consecutive patients with a solid SRM without macroscopic fat (mean size +/- SD, 2.5 +/- 0.8 cm) who underwent CT including unenhanced, corticomedullary (CMP), and nephrographic phases (NP) were evaluated. Pathologically proven solid SRMs without macroscopic fat were classified into RCC (n = 131) and not RCC (n = 19). A "persistent low" sign was defined as a focal area or areas of low attenuation seen at the same location within the lesion on both CMP and NP imaging. Calcification, shape, and lesion attenuation on unenhanced CT were analyzed by two independent readers. RESULTS: PPV of CT criteria (calcification [criterion 1] or spherical shape, lower or equal attenuation, and persistent low sign [criterion 2]) for RCC was 98.3% (58/59) for reader 1 and 100% (53/53) for reader 2. Weighted kappa of interreader agreement was 1.000 for calcification, 0.966 of lower or equal attenuation, 0.834 for spherical shape, 0.823 for persistent low sign, and 0.829 for CT criteria. CONCLUSION: Interpretation of CT allowed reproducible and excellent PPV for RCC. Current CT criteria may effectively shorten the management process for solid SRMs without macroscopic fat by reducing unnecessary biopsy for a substantial number of RCCs showing typical CT findings. PMID- 29470158 TI - The Clinical Significance of Osteophytes in Compartments of the Knee Joint With Normal Articular Cartilage. AB - OBJECTIVE: The purpose of this study is to determine whether marginal osteophytes in compartments with normal cartilage would be more frequently observed in knees with cartilage lesions and osteophytes in other compartments. MATERIALS AND METHODS: This retrospective study reviewed 500 consecutive knee MRI examinations performed within 6 months of arthroscopic knee surgery conducted for 497 patients with symptoms (289 male patients and 208 female patients; age range, 17-74 years; median age, 43 years). The highest grade of cartilage lesion detected at MRI and arthroscopy was recorded. Marginal osteophytes were graded on MRI with use of a standardized scoring system, with grade 0 denoting no osteophyte; grade 1, small osteophyte; grade 2, medium-size osteophyte; and grade 3, large osteophyte). The frequency of false-positive osteophytes, defined as osteophytes present in compartments (the patellofemoral, medial tibiofemoral, and lateral tibiofemoral compartments) with normal cartilage observed on MRI and arthroscopy, was calculated. The Goodman and Kruskal gamma statistic was used to test the association of osteophyte size between compartments. Logistic regression was used to test the association between osteophyte size and the severity of the cartilage lesions. RESULTS: Marginal osteophytes were seen in compartments with normal cartilage on MRI and arthroscopy in 60.5% of knees (75 of 124) with cartilage lesions and osteophytes in other compartments and accounted for all false positive grade 2 and grade 3 osteophytes. Marginal osteophytes were seen in 12.7% of knees (13 of 102) that had no cartilage lesions in any compartment on MRI or arthroscopy, and all of these were grade 1 osteophytes. The presence of larger sized osteophytes in the compartments with cartilage lesions was associated with the presence of larger sized osteophytes in the compartments with normal cartilage. More severe cartilage lesions were associated with larger osteophyte size. CONCLUSION: Compartments with marginal osteophytes and normal cartilage are commonly seen in knees that have other compartments with osteophytes and cartilage lesions. PMID- 29470159 TI - Central Metatarsalgia and Walking on Pebbles: Beyond Morton Neuroma. AB - OBJECTIVE: Central metatarsalgia relates to abnormalities of the second, third, and fourth metatarsals and their respective metatarsophalangeal joints. A variety of disorders present with central forefoot pain; they range from traumatic lesions (acute or chronic repetitive), inflammatory and infective disorders, nonneoplastic soft-tissue lesions, and benign tumors to malignant lesions. Patients often present with symptoms of localized pain in the forefoot that worsens on weight bearing (walking or running), which can be sharp or dull and often is perceived as a lump felt inside or underneath the foot and described as walking on a marble or pebbles. These patients are labeled as having central metatarsalgia and are further evaluated with ultrasound or MRI to establish a diagnosis. CONCLUSION: In this article, we review metatarsal and intermetatarsal lesions of the foot that present with central forefoot pain and a sensation of walking on pebbles, focusing on conditions mimicking Morton neuroma clinically or on imaging. We also briefly review some other plantar lesions and arthropathy that can present with awareness of lump underneath the foot. PMID- 29470160 TI - Contribution of 3-T Susceptibility-Weighted MRI to Detection of Intraarticular Hemosiderin Accumulation in Patients With Hemophilia. AB - OBJECTIVE: The purpose of this study was to assess the feasibility of 3-T susceptibility-weighted imaging (SWI) for detecting intraarticular hemosiderin accumulation in patients with hemophilia. SUBJECTS AND METHODS: Forty-one joints in 24 patients with hemophilia were imaged with conventional MRI and SWI sequences. Two experienced musculoskeletal radiologists and one general radiologist (reader 3) interpreted the images for hemosiderin accumulation. The final decision was determined in consensus by readers 1 and 2 using both conventional MRI and SWI sequences. The diagnostic consistencies of each MRI sequence with the reference and pairwise agreements between interpreters were assessed. RESULTS: For conventional MRI sequences, the diagnostic consistencies of the two experienced musculoskeletal radiologists with the reference were substantial (kappa = 0.63 and 0.62), whereas the consistency of the general radiologist with the reference was moderate (kappa = 0.47). The SWI interpretations of all readers had almost perfect agreement with the reference (kappa = 1, kappa = 1, kappa = 0.97). Interobserver agreement also improved at SWI interpretations. CONCLUSION: SWI contributes to more accurate grading of intraarticular hemosiderin accumulation than is achieved with conventional MRI sequences. PMID- 29470161 TI - The Child With Macrocephaly: Differential Diagnosis and Neuroimaging Findings. AB - OBJECTIVE: The purpose of this article is to offer a systematic approach to the imaging of children with macrocephaly and to illustrate key neuroimaging features of common and rare but important disorders. CONCLUSION: Macrocephaly is a common clinical finding in children. Increased volume of one of the intracranial compartments can enlarge the head either prenatally or postnatally while the cranial sutures are open. Imaging plays a central role in establishing a diagnosis and guiding management. PMID- 29470162 TI - Pulmonary Mucormycosis: Radiologic Features at Presentation and Over Time. AB - OBJECTIVE: Pulmonary mucormycosis is an aggressive opportunistic fungal infection. We set out to evaluate the CT and MRI features of pulmonary mucormycosis. MATERIALS AND METHODS: Through a search of the electronic medical record from 2007 to 2017, we identified 30 patients with definite or probable mucormycosis. Two radiologists reviewed the initial chest CT examinations for the presence of features including the "reverse halo" sign, large ground-glass halo, and peripheral lesion distribution. Additional CT and MRI studies were reviewed to evaluate evolution over time. RESULTS: The majority (67%) of patients had lesions with the reverse halo sign at some point in the disease course. A ground glass halo larger than the lesion was seen in 53% of patients. Notably, lesions had a peripheral predominance in 87% of cases. Through careful review of images, a perivascular ground-glass precursor lesion was identified in 20% of patients 1 2 weeks before a consolidation developed. In five (17%) patients, CT showed a multifocal pneumonia appearance. Finally, MRI of two patients showed T2 hypointense rims and central nonenhancement, a finding we refer to as the "black hole" sign. CONCLUSION: Large nodules or consolidations with an associated reverse halo sign or large perilesional ground-glass halos are common in mucormycosis. Lesions tend to show a peripheral predominance, and a perivascular ground-glass focus preceded nodular lesions in some cases. In some patients with severe disease, imaging features evolved to show a multifocal pneumonia pattern, and this pattern was associated with a high mortality rate. PMID- 29470163 TI - Abdominal Exploration in Neonates Using Transumbilical Exposure Compared with Transverse Laparotomies. AB - INTRODUCTION: The vertical transumbilical incision (TU) technique during neonatal abdominal exploration involves dissection and ligation of umbilical vessels, which allow access to all quadrants of the abdomen and complete bowel evisceration with minimal violation to the anterior abdominal wall. We compared patient characteristics and outcomes for neonates undergoing TU with standard transverse exploration. MATERIALS AND METHODS: A single-center retrospective review of neonates who underwent abdominal exploration between January 2010 and September 2015 was conducted after obtaining Institutional Review Board approval. Data included patient demographics, indication for operative intervention, operative details, complications, including incisional hernias, and long-term outcomes. RESULTS: There were 88 neonates under 4 months of age who underwent abdominal exploration, with a median age of 5.5 +/- 17 days and a median gestational age of 32.8 +/- 16 weeks. Exploration was emergent in 38 patients (43%) and 49 (56%) required ostomy formation. A transverse incision (TV) was used in 30 patients and a TU in 58 patients. Both groups had similar postoperative complication rates; 27 (47%) in the TU group and 11 (36%) in the TV group, P = .51. Median length of follow-up in the TU group was 5.1 +/- 18 months and 6.2 +/- 16 months in the TV group, P = .48. The TU group had 4 incisional/umbilical hernias (7%), none have required repair. CONCLUSION: TUs for abdominal explorations in neonates have similar outcomes as the standard TV while preserving the integrity of the anterior abdominal wall.

AB - INTRODUCTION: We conducted this study to quantify how health professionals use Twitter to communicate about the human papillomavirus (HPV) vaccine. METHODS: We collected 193,379 tweets from August 2014 through July 2015 that contained key words related to HPV vaccine. We classified all tweets on the basis of user, audience, sentiment, content, and vaccine characteristic to examine 3 groups of tweets: 1) those sent by health professionals, 2) those intended for parents, and 3) those sent by health professionals and intended for parents. For each group, we identified the 7-day period in our sample with the most number of tweets (spikes) to report content. RESULTS: Of the 193,379 tweets, 20,451 tweets were from health professionals; 16,867 tweets were intended for parents; and 1,233 tweets overlapped both groups. The content of each spike varied per group. The largest spike in tweets from health professionals (n = 851) focused on communicating recently published scientific evidence. Most tweets were positive and were about resources and boys. The largest spike in tweets intended for parents (n = 1,043) centered on a national awareness day and were about resources, personal experiences, boys, and girls. The largest spike in tweets from health professionals to parents (n = 89) was in January and centered on an event hosted on Twitter that focused on cervical cancer awareness month. CONCLUSION: Understanding drivers of tweet spikes may help shape future communication and outreach. As more parents use social media to obtain health information, health professionals and organizations can leverage awareness events and personalize messages to maximize potential reach and parent engagement.

AB - INTRODUCTION: Hispanic women in the United States have an elevated risk of cervical cancer, but the existing literature does not reveal why this disparity persists. METHODS: We performed a retrospective cohort analysis of 17,828 low income women aged 21 to 64 years seeking care at Oregon community health centers served by a hosted, linked electronic health record during 2009 through 2013. We assessed the odds of having had Papanicolaou (Pap) tests and receiving human papillomavirus (HPV) vaccine, by race/ethnicity, insurance status, and language. RESULTS: Hispanic women, regardless of pregnancy status or insurance, had greater odds of having had Pap tests than non-Hispanic white women during the study period. English-preferring Hispanic women had higher odds of having had Pap tests than Spanish-preferring Hispanic women (OR, 2.08; 95% confidence interval [CI], 1.63-2.66) but lower odds of having received HPV vaccination (OR, 0.21; 95% CI, 0.12-0.38). Uninsured patients, regardless of race/ethnicity, had lower odds of HPV vaccine initiation than insured patients did. Once a single dose was received, there were no significant racial/ethnic differences in vaccine series completion. CONCLUSION: In this sample of low-income women seeking care at Oregon community health centers, we found minimal racial/ethnic disparities in the receipt of cervical cancer prevention services. Inequities by insurance status, especially in the receipt of HPV vaccine, persist. Community health center-based care may be a useful model to address racial/ethnic disparities in prevention, but this model would need further population-wide study. PMID- 29470168 TI - Evaluation of the Healthy Lifestyles Initiative for Improving Community Capacity for Childhood Obesity Prevention. AB - PURPOSE AND OBJECTIVES: Policy, systems, and environmental approaches are recommended for preventing childhood obesity. The objective of our study was to evaluate the Healthy Lifestyles Initiative, which aimed to strengthen community capacity for policy, systems, and environmental approaches to healthy eating and active living among children and families. INTERVENTION APPROACH: The Healthy Lifestyles Initiative was developed through a collaborative process and facilitated by community organizers at a local children's hospital. The initiative supported 218 partners from 170 community organizations through training, action planning, coalition support, one-on-one support, and the dissemination of materials and sharing of resources. EVALUATION METHODS: Eighty initiative partners completed a brief online survey on implementation strategies engaged in, materials used, and policy, systems, and environmental activities implemented. In accordance with frameworks for implementation science, we assessed associations among the constructs by using linear regression to identify whether and which of the implementation strategies were associated with materials used and implementation of policy, systems, and environmental activities targeted by the initiative. RESULTS: Each implementation strategy was engaged in by 30% to 35% of the 80 survey respondents. The most frequently used materials were educational handouts (76.3%) and posters (66.3%). The most frequently implemented activities were developing or continuing partnerships (57.5%) and reviewing organizational wellness policies (46.3%). Completing an action plan and the number of implementation strategies engaged in were positively associated with implementation of targeted activities (action plan, effect size = 0.82; number of strategies, effect size = 0.51) and materials use (action plan, effect size = 0.59; number of strategies, effect size = 0.52). Materials use was positively associated with implementation of targeted activities (effect size = 0.35). IMPLICATIONS FOR PUBLIC HEALTH: Community-capacity-building efforts can be effective in supporting community organizations to engage in policy, systems, and environmental activities for healthy eating and active living. Multiple implementation strategies are likely needed, particularly strategies that involve a high level of engagement, such as training community organizations and working with them on structured action plans. PMID- 29470169 TI - Multi-Attributed Graph Matching With Multi-Layer Graph Structure and Multi-Layer Random Walks. AB - This paper addresses the multi-attributed graph matching problem, which considers multiple attributes jointly while preserving the characteristics of each attribute for graph matching. Since most of conventional graph matching algorithms integrate multiple attributes to construct a single unified attribute in an oversimplified manner, the information from multiple attributes is often not completely utilized. In order to solve this problem, we propose a novel multi layer graph structure that can preserve the characteristics of each attribute in separated layers, and also propose a multi-attributed graph matching algorithm based on random walk centrality with the proposed multi-layer graph structure. We compare the proposed algorithm with other state-of-the-art graph matching algorithms based on a single-layer structure using synthetic and real data sets and demonstrate the superior performance of the proposed multi-layer graph structure and the multi-attributed graph matching algorithm. PMID- 29470171 TI - Hyperspectral Image Classification With Markov Random Fields and a Convolutional Neural Network. AB - This paper presents a new supervised classification algorithm for remotely sensed hyperspectral image (HSI) which integrates spectral and spatial information in a unified Bayesian framework. First, we formulate the HSI classification problem from a Bayesian perspective. Then, we adopt a convolutional neural network (CNN) to learn the posterior class distributions using a patch-wise training strategy to better use the spatial information. Next, spatial information is further considered by placing a spatial smoothness prior on the labels. Finally, we iteratively update the CNN parameters using stochastic gradient decent and update the class labels of all pixel vectors using -expansion min-cut-based algorithm. Compared with the other state-of-the-art methods, the classification method achieves better performance on one synthetic data set and two benchmark HSI data sets in a number of experimental settings. PMID- 29470170 TI - Sub-Network Kernels for Measuring Similarity of Brain Connectivity Networks in Disease Diagnosis. AB - As a simple representation of interactions among distributed brain regions, brain networks have been widely applied to automated diagnosis of brain diseases, such as Alzheimer's disease (AD) and its early stage, i.e., mild cognitive impairment (MCI). In brain network analysis, a challenging task is how to measure the similarity between a pair of networks. Although many graph kernels (i.e., kernels defined on graphs) have been proposed for measuring the topological similarity of a pair of brain networks, most of them are defined using general graphs, thus ignoring the uniqueness of each node in brain networks. That is, each node in a brain network denotes a particular brain region, which is a specific characteristics of brain networks. Accordingly, in this paper, we construct a novel sub-network kernel for measuring the similarity between a pair of brain networks and then apply it to brain disease classification. Different from current graph kernels, our proposed sub-network kernel not only takes into account the inherent characteristic of brain networks, but also captures multi level (from local to global) topological properties of nodes in brain networks, which are essential for defining the similarity measure of brain networks. To validate the efficacy of our method, we perform extensive experiments on subjects with baseline functional magnetic resonance imaging data obtained from the Alzheimer's disease neuroimaging initiative database. Experimental results demonstrate that the proposed method outperforms several state-of-the-art graph based methods in MCI classification. PMID- 29470172 TI - Hookworm Detection in Wireless Capsule Endoscopy Images With Deep Learning. AB - As one of the most common human helminths, hookworm is a leading cause of maternal and child morbidity, which seriously threatens human health. Recently, wireless capsule endoscopy (WCE) has been applied to automatic hookworm detection. Unfortunately, it remains a challenging task. In recent years, deep convolutional neural network (CNN) has demonstrated impressive performance in various image and video analysis tasks. In this paper, a novel deep hookworm detection framework is proposed for WCE images, which simultaneously models visual appearances and tubular patterns of hookworms. This is the first deep learning framework specifically designed for hookworm detection in WCE images. Two CNN networks, namely edge extraction network and hookworm classification network, are seamlessly integrated in the proposed framework, which avoid the edge feature caching and speed up the classification. Two edge pooling layers are introduced to integrate the tubular regions induced from edge extraction network and the feature maps from hookworm classification network, leading to enhanced feature maps emphasizing the tubular regions. Experiments have been conducted on one of the largest WCE datasets with WCE images, which demonstrate the effectiveness of the proposed hookworm detection framework. It significantly outperforms the state-of-the-art approaches. The high sensitivity and accuracy of the proposed method in detecting hookworms shows its potential for clinical application. PMID- 29470173 TI - Preemptive NUDT15 genotyping: redefining the management of patients with thiopurine-induced toxicity. AB - BACKGROUND: Thiopurine methyltransferase (TPMT) gene variants have achieved limited success in predicting the outcome of thiopurine therapy, which shows wide inter-individual variations. The literature indicates a strong association between the NUDT15 gene variant and thiopurine-induced toxicity in Asian patients. The present study intends to explore the role of the NUDT15 variant (C415T) in Indian patients on thiopurine therapy. METHODS: NUDT15 and TPMT genotyping were performed using amplification-refractory mutation system polymerase chain reaction (ARMS-PCR) and the restriction fragment length polymorphism (RFLP) technique. RESULTS: Of 370 samples received for TPMT testing, 206 samples were available for NUDT15 genotyping. The NUDT15 risk allele frequency was 10.7%, with the frequency of wild, heterozygous and mutant genotypes being 80.6%, 17.5% and 1.9%, respectively. TPMT variants were seen in 13 of 370 (3.5%) patients, whereas the NUDT15 variant was seen in 40 of 206 (19.4%) patients. Thiopurine-induced toxicity information was available for 101 patients, among whom 10 developed leukopenia and all harbored the NUDT15 variant (p<0.0001). NUDT15 was clinically more relevant than TPMT in terms of sensitivity and specificity, as well as with a statistically significant difference in thiopurine dose requirement for patients with the NUDT15 variant. CONCLUSIONS: A preemptive NUDT15 genotyping approach can therefore help identify high-risk patients (NUDT15 C415T positive) who could benefit from thiopurine dose reduction, thereby preventing fatal thiopurine-induced toxicity.

PMID- 29470175 TI - Modified HuffBit Compress Algorithm - An Application of R. AB - The databases of genomic sequences are growing at an explicative rate because of the increasing growth of living organisms. Compressing deoxyribonucleic acid (DNA) sequences is a momentous task as the databases are getting closest to its threshold. Various compression algorithms are developed for DNA sequence compression. An efficient DNA compression algorithm that works on both repetitive and non-repetitive sequences known as "HuffBit Compress" is based on the concept of Extended Binary Tree. In this paper, here is proposed and developed a modified version of "HuffBit Compress" algorithm to compress and decompress DNA sequences using the R language which will always give the Best Case of the compression ratio but it uses extra 6 bits to compress than best case of "HuffBit Compress" algorithm and can be named as the "Modified HuffBit Compress Algorithm". The algorithm makes an extended binary tree based on the Huffman Codes and the maximum occurring bases (A, C, G, T). Experimenting with 6 sequences the proposed algorithm gives approximately 16.18 % improvement in compression ration over the "HuffBit Compress" algorithm and 11.12 % improvement in compression ration over the "2-Bits Encoding Method". PMID- 29470176 TI - Association of insulin-like growth factor-1 and IGF binding protein-3 with 25 hydroxy vitamin D in pre-pubertal and adolescent Indian girls. AB - BACKGROUND: There is a high prevalence of vitamin D deficiency (VDD) in India. Molecular mechanisms suggest a strong relationship between vitamin D and growth factors. However, there is a paucity of literature with regard to a relationship between insulin-like growth factor-1 (IGF-1), insulin-like growth factor binding protein-3 (IGFBP-3) and vitamin D particularly in subjects with VDD. The objective of the study was to assess the relationship between growth factors and serum vitamin D-parathormone (PTH) status in school girls and study the impact of vitamin D supplementation on growth factors in pre-pubertal girls with VDD. METHODS: Our study subjects were apparently healthy school girls aged 6-18 years. The baseline height, weight, body mass index (BMI), pubertal status, serum 25 hydroxy vitamin D (25OHD), PTH, IGF-1 and IGFBP-3 were assessed in 847 girls aged 6-18 years and in 190 pre-pubertal girls with VDD following supplementation. RESULTS: The mean age, BMI and serum 25OHD of girls were 11.5+/-3.2 years, 18.7+/ 4.8 kg/m2 and 9.9+/-5.6 ng/mL, respectively. VDD was observed in 94.6% of girls. Unadjusted serum IGF-1 levels and IGF-1/IGFBP-3 molar ratio were significantly higher in girls with severe VDD as compared to girls with mild-to-moderate VDD. However, these differences disappeared when adjusted for age, height or sexual maturation. The serum IGF-1 and IGFBP-3 levels increased significantly post supplementation with vitamin D. CONCLUSIONS: There were no differences in serum IGF-1 levels and the IGF-1/IGFBP-3 molar ratio among VDD categories when adjusted for age, height and sexual maturation in girls. Vitamin D supplementation resulted in a significant increase in serum IGF-1 levels in VDD pre-pubertal girls. PMID- 29470177 TI - Investigating the changes in amino acid values in premature infants: a pilot study. AB - BACKGROUND: The objective of the study was to investigate the changes in amino acid (AAs) values in premature infants. METHODS: A total of 2159 premature and/or low birth weight infants were recruited for this study. They were divided into three groups: premature infants with normal birth weight (G1), simple low birth weight infants (G2) and premature combined with low birth weight infants (G3). The tandem mass spectrometry technique was used to detect the levels of 11 AAs in neonatal blood. RESULTS: Compared with normal babies, there were eight and five AAs that significantly changed in G1 and G2, respectively. It was worth noting that the changes greatly exacerbated when the babies were both premature and of low birth weight. All the levels of AAs demonstrated significant changes in G3 compared with the normal control group (G4). With the increase in gestational age, the AAs in premature infants tended to the levels in normal newborns. Meanwhile, there was a correlation between AAs and birth weight. Four AAs significantly changed with the increase in body weight. Among normal newborns, the levels of AAs in girls were significantly higher than in boys. However, if the newborns were premature or had low birth weight, the differences between AA values and sexual distinction would decrease. In the end, we established the specific reference ranges of AAs for premature and/or low birth weight infants. CONCLUSIONS: There were significant differences in AAs in the premature and/or low birth weight infants. Gestational age and birth weight were two important factors inflecting the AAs metabolism.

PMID- 29470180 TI - Opioid Abuse or Dependence Increases 30-day Readmission Rates after Major Operating Room Procedures: A National Readmissions Database Study. AB - BACKGROUND: Although opioids remain the standard therapy for the treatment of postoperative pain, the prevalence of opioid misuse is rising. The extent to which opioid abuse or dependence affects readmission rates and healthcare utilization is not fully understood. It was hypothesized that surgical patients with a history of opioid abuse or dependence would have higher readmission rates and healthcare utilization. METHODS: A retrospective cohort analysis was performed of patients undergoing major operating room procedures in 2013 and 2014 using the National Readmission Database. Patients with opioid abuse or dependence were identified using International Classification of Diseases codes. The primary outcome was 30-day hospital readmission rate. Secondary outcomes included hospital length of stay and estimated hospital costs. RESULTS: Among the 16,016,842 patients who had a major operating room procedure whose death status was known, 94,903 (0.6%) had diagnoses of opioid abuse or dependence. After adjustment for potential confounders, patients with opioid abuse or dependence had higher 30-day readmission rates (11.1% vs. 9.1%; odds ratio 1.26; 95% CI, 1.22 to 1.30), longer mean hospital length of stay at initial admission (6 vs. 4 days; P < 0.0001), and higher estimated hospital costs during initial admission ($18,528 vs. $16,617; P < 0.0001). Length of stay was also higher at readmission (6 days vs. 5 days; P < 0.0001). Readmissions for infection (27.0% vs. 18.9%; P < 0.0001), opioid overdose (1.0% vs. 0.1%; P < 0.0001), and acute pain (1.0% vs. 0.5%; P < 0.0001) were more common in patients with opioid abuse or dependence. CONCLUSIONS: Opioid abuse and dependence are associated with increased readmission rates and healthcare utilization after surgery. VISUAL ABSTRACT: An online visual overview is available for this article at http://links.lww.com/ALN/B704. PMID- 29470181 TI - Prevention and Management of Thromboembolism in Pregnancy When Heparins Are Not an Option. AB - Heparins, unfractionated heparin, and low molecular weight heparin, are the preferred anticoagulants in pregnancy. There are circumstances, however, in which an alternative to heparin should be considered. These circumstances include, the presence of heparin resistance, a heparin allergy manifesting as heparin-induced skin reactions or heparin-induced thrombocytopenia, and the presence of a mechanical heart valve. From time to time, the obstetrician is called on to make recommendations about anticoagulants in pregnancy, including in circumstances in which an alternative to heparin has been suggested or is necessary. In this article, these circumstances are reviewed and alternative anticoagulants are discussed. PMID- 29470182 TI - Diagnosis and Management of VTE in Pregnancy. AB - Venous thromboembolism is a leading cause of maternal death. Because of the low absolute frequency of events, however, outcome-based clinical data are limited. Consequently, clinicians must additionally rely both on published guidelines and on extrapolation of data from studies focused on nonpregnant individuals. The diagnosis and treatment of deep vein thrombosis, pulmonary embolism, and cerebral vein and dural sinus thrombosis are complicated by pregnancy, and often require modifications to standard diagnostic and treatment algorithms outside of pregnancy. Treatment of VTE in pregnant women is in particular need of future research. PMID- 29470183 TI - The Central Effects of Androgenic-anabolic Steroid Use. AB - : Millions of men use androgenic-anabolic steroids (AAS) to stimulate muscle growth and improve physical appearance. Although 1 out of 3 people who uses androgenic-anabolic steroids develops a steroid use disorder, the effects of the drugs on the central nervous system and the psyche are still not well understood. Although most addictive substances improve mood immediately after administration, AAS exert less pronounced euphoric effects. Instead, they are primarily taken for the delayed gratification of increased muscle mass. Withdrawal from AAS may lead to a range of somatic and psychiatric symptoms, and, in many cases, comprehensive treatment supervised by an endocrinologist and a psychiatrist is required. PMID- 29470184 TI - Impact of 3D virtual planning on reconstruction of mandibular and maxillary surgical defects in head and neck oncology. AB - PURPOSE OF REVIEW: This review describes the advances in 3D virtual planning for mandibular and maxillary reconstruction surgical defects with full prosthetic rehabilitation. The primary purpose is to provide an overview of various techniques that apply 3D technology safely in primary and secondary reconstructive cases of patients suffering from head and neck cancer. RECENT FINDINGS: Methods have been developed to overcome the problem of control over the margin during surgery while the crucial decision with regard to resection margin and planning of osteotomies were predetermined by virtual planning. The unlimited possibilities of designing patient-specific implants can result in creative uniquely applied solutions for single cases but should be applied wisely with knowledge of biomechanical engineering principles. SUMMARY: The high surgical accuracy of an executed 3D virtual plan provides tumor margin control during ablative surgery and the possibility of planned combined use of osseus free flaps and dental implants in the reconstruction in one surgical procedure. A thorough understanding of the effects of radiotherapy on the reconstruction, soft tissue management, and prosthetic rehabilitation is imperative in individual cases when deciding to use dental implants in patients who received radiotherapy. PMID- 29470185 TI - Psychological Factors and the Development of Chronic Whiplash-associated Disorder(s): A Systematic Review. AB - OBJECTIVES: To assess which psychological factors are important in the development of chronic whiplash symptoms. METHODS: Searches were conducted across PubMed, CINAHL, Scopus, and PsychINFO up until March 2017. Studies were included if they investigated psychological prognostic factors in association with recovery from a whiplash injury. Studies also had to be prospective, cohort, follow-up or observational studies, have a 6 month follow-up and published in English. Quality assessments were conducted by 2 independent reviewers. Thirty one articles were included investigating 34 psychological factors. RESULTS: Poor expectations of recovery, posttraumatic stress symptoms and passive coping emerged as the most consistent prognostic factors of chronic neck pain and/or disability after a whiplash injury. Anxiety, travel anxiety, depression, personality, precollision distress, general psychological distress, and avoidance behavior were not associated with chronic whiplash problems. PMID- 29470186 TI - A Comparison of Outcomes Between Open Hysterectomy and Robotic-Assisted Hysterectomy for Endometrial Cancer Using the National Cancer Database. AB - PURPOSE: The purpose of this study is to evaluate usage patterns and outcomes of women who underwent open hysterectomy (OH) versus robotic assisted-hysterectomy (RAH) for the treatment of endometrial cancer. METHODS: Women with nonmetastatic endometrial adenocarcinoma diagnosed between 2010 and 2012, who either underwent an OH or RAH, were selected from the National Cancer Database. The chi, Fisher exact, or Mann-Whitney U tests were used where appropriate to compare outcomes between groups. Multivariable logistic regression was used to analyze for predictors for RAH and other outcome variables. RESULTS: A total of 43,985 women were included in this study with a median age of 61 years. Of these, 23,872 (54.3%) underwent RAH and 20,113 (45.7%) underwent OH. The usage of RAH increased from 43.0% in 2010 to 63.8% in 2012 (P < 0.001). Women receiving RAH were more commonly found to have a Charlson comorbidity score of 0 to 1, lower pathologic stage, nonblack race, treatment at a comprehensive center, and had insurance other than Medicaid. Robotic-assisted hysterectomy was associated with a shorter inpatient stay, lower readmission rates, and lower 30- and 90-day mortality rates (P < 0.001 for all comparisons). There was a significant improvement in overall survival favoring RAH, 96.1% versus 94.0%, which persisted on multivariable logistic regression (P < 0.001). CONCLUSIONS: In this large, hospital-based analysis, RAH was associated with decreased length of stay, lower readmission rates, and less perioperative mortality. However, socioeconomic status continues to remain a barrier to equal treatment allocation. Overall survival was improved with RAH, but the follow-up is limited, and this finding must be interpreted with caution. PMID- 29470187 TI - The Danish Gynecological Cancer Nursing Database: Creating Evidence for Quality Improvements in Preoperative and Postoperative Cancer Care. AB - OBJECTIVE: Quality of preoperative and postoperative care is crucial to improve postoperative outcome of cancer surgery and to ensure that neither complications nor a poor general condition delays any subsequent radiochemotherapy or recovery. On this background, the Danish Gynecological Cancer Database (DGCD) established a nursing database in 2011. The aim of DGCD Nursing is to monitor the quality of preoperative and postoperative care and to generate data for research. MATERIAL AND METHODS: In accordance with the current data protection legislation, real time data are entered by clinical nurses at all national cancer centers. The DGCD Nursing includes data of preoperative and postoperative care, and nurses are independently represented in the steering committee. The aim of the present article is to present the first results from DGCD Nursing and the national care improvements that have followed. RESULTS: With national coverage of an average of 94%, 5726 patients have been registered since 2011. In patients undergoing surgery for ovarian, endometrial, and cervical cancer, 436 different variables monitor central preoperative and postoperative care elements within mobilization, nutritional status, pain score, vital functions, and psychosocial support. CONCLUSIONS: At national level, DGCD offers a comprehensive overview of the total patient pathway within gynecological cancer surgery. The DGCD Nursing has added to the quality and implementation of evidence-based preoperative and postoperative care and in addition supported formation of professional networks. With a continued validation of data, DGCD Nursing now constitutes a sound and unique basis for research within the field of preoperative and postoperative cancer care. PMID- 29470188 TI - Extrapelvic Sentinel Lymph Nodes in Endometrial Cancer Patients With Unmapped Pelvic Side: A Brief Report. AB - OBJECTIVE: The aim of the study was to evaluate extrapelvic sentinel lymph nodes (SLNs) in clinical early-stage endometrial cancer patients with unmapped pelvic side(s) during fluorescent imaging-based sentinel mapping. MATERIALS AND METHODS: Eligible patients underwent sentinel mapping using cervical injection of indocyanine green and near-infrared florescent imaging compatible endoscopic systems. Pelvic SLNs were identified and resected. If bilateral mapping was not achieved, upper lymph nodes areas including presacral, upper common iliac, and para-aortic caval regions were explored for any SLN. Systematic lymphadenectomy was performed after applying SLN algorithm steps. RESULTS: In 24 of 101 patients, bilateral pelvic mapping was not achieved. Bilateral unmapping was seen in 4 of 24 and unilateral pelvic side mapping in 20 of 24 patients. There was no extrapelvic SLN among 4 cases with bilateral pelvic unmapping, whereas 8 (40%) of 20 patients with unilateral pelvic mapping had extrapelvic SLNs. Five of extrapelvic SLNs were in presacral, 2 in upper common iliac, and 1 in paracaval regions. CONCLUSIONS: Observing for extrapelvic SLNs in cases with unmapped pelvic side(s) could increase detection rate of SLN mapping in clinical early stage endometrial cancer. PMID- 29470189 TI - Letter From the Editor, March 2018. PMID- 29470190 TI - Blood transfusion management in the severely bleeding military patient. AB - PURPOSE OF REVIEW: Hemorrhage remains the primary cause of preventable death on the battlefield and in civilian trauma. Hemorrhage control is multifactorial and starts with point-of-injury care. Surgical hemorrhage control and time from injury to surgery is paramount; however, interventions in the prehospital environment and perioperative period affect outcomes. The purpose of this review is to understand concepts and strategies for successful management of the bleeding military patient. Understanding the life-threatening nature of coagulopathy of trauma and implementing strategies aimed at full spectrum hemorrhage management from point of injury to postoperative care will result in improved outcomes in patients with life-threatening bleeding. RECENT FINDINGS: Timely and appropriate therapies impact survival. Blood product resuscitation for life-threatening hemorrhage should either be with whole blood or a component therapy strategy that recapitulates the functionality of whole blood. The US military has transfused over 10 000 units of whole blood since the beginning of the wars in Iraq and Afghanistan. The well recognized therapeutic benefits of whole blood have pushed this therapy far forward into prehospital care in both US and international military forces. Multiple hemostatic adjuncts are available that are likely beneficial to the bleeding military patient; and other products and techniques are under active investigation. SUMMARY: Lessons learned in the treatment of combat casualties will likely continue to have positive impact and influence and the management of hemorrhage in the civilian trauma setting. PMID- 29470192 TI - Sensitivity of a Reduced EEG Montage for Seizure Detection in the Neurocritical Care Setting. AB - INTRODUCTION: Neurocritical care units commonly implement the double-distance reduced EEG montage in postoperative neurosurgic patients who have structural barriers that hinder the placement of a standard 10-20 system array. Despite its widespread use, its sensitivity has not been adequately addressed. We evaluated the sensitivity and specificity of this montage for seizure detection. METHODS: One hundred fifty-five full-montage continuous EEGs (cEEGs) completed in the Johns Hopkins University neurocritical care unit containing unequivocal electrographic seizures, status epilepticus, or other abnormalities were selected, comprising 73 ictal and 82 nonictal EEGs. EEGs were reformatted to the reduced montage, and 2-hour clips were reviewed independently by 2 epileptologists who documented the presence of seizures, status, or background abnormalities. RESULTS: The sensitivity and specificity of the reduced montage for electrographic seizure detection was 81% and 92% with substantial interrater agreement (kappa 0.71). The sensitivity for status epilepticus was lower at 69%, but specificity remained high at 97% (kappa 0.67). Several EEGs miscategorized as nonictal were labeled as rather having rhythmic activity or periodic discharges. Evaluation of background patterns on the ictal-interictal continuum resulted in sensitivities ranging from 68% to 83%. CONCLUSIONS: Although the specificity of the reduced array is good, epileptologists should remain vigilant when monitoring patients using this montage, given its reduced sensitivity for epileptic activity, especially status epilepticus. PMID- 29470191 TI - Characterization of Postinfusion Phenotypic Differences in Fresh Versus Cryopreserved TCR Engineered Adoptive Cell Therapy Products. AB - Adoptive cell therapy (ACT) consisting of genetically engineered T cells expressing tumor antigen-specific T-cell receptors displays robust initial antitumor activity, followed by loss of T-cell activity/persistence and frequent disease relapse. We characterized baseline and longitudinal T-cell phenotype variations resulting from different manufacturing and administration protocols in patients who received ACT. Patients with melanoma who enrolled in the F5-MART-1 clinical trial (NCT00910650) received infusions of MART-1 T-cell receptors transgenic T cells with MART-1 peptide-pulsed dendritic cell vaccination. Patients were divided into cohorts based on several manufacturing changes in the generation and administration of the transgenic T cells: decreasing ex vivo stimulation/expansion time, increased cell dose, and receiving fresh instead of cryopreserved cells. T-cell phenotypes were analyzed by flow cytometry at baseline and longitudinally in peripheral blood. Transgenic T cells with shorter ex vivo culture/expansion periods displayed significantly increased expression of markers associated with less differentiated naive/memory populations, as well as significantly decreased expression of the inhibitory receptor programmed death 1 (PD1). Patients receiving fresh infusions of transgenic cells demonstrated expansion of central memory T cells and delayed acquisition of PD1 expression compared with patients who received cryopreserved products. Freshly infused transgenic T cells showed persistence and expansion of naive and memory T-cell populations and delayed acquisition of PD1 expression, which correlated with this cohort's superior persistence of transgenic cells and response to dendritic cell vaccines. These results may be useful in designing future ACT protocols. PMID- 29470193 TI - Breakthrough Reactions to Gadobenate Dimeglumine. AB - PURPOSE: The aim of this study was to determine the severity of breakthrough reactions to gadobenate dimeglumine in patients premedicated with a 13-hour premedication regimen. METHODS: Institutional review board approval was obtained and informed consent waived for this Health Insurance Portability and Accountability Act-compliant retrospective cohort study. All acute allergic-like reactions to gadobenate dimeglumine from 11/1/2008 to 1/31/2016 were identified. Of these, 19 allergic-like reactions followed 13-hour premedication: 150 mg prednisone and 50 mg diphenhydramine (ie, "breakthrough reactions"). Reasons for premedication, risk factors, index reaction characteristics, and breakthrough reaction characteristics were catalogued. Reaction severities were assigned using American College of Radiology guidelines. Severities of breakthrough (n = 19) and nonbreakthrough reactions (n = 97) were compared with the Cochran-Armitage test for trend. RESULTS: Premedication was most commonly given (63% [12/19]) for a previous allergic-like reaction to gadolinium-based contrast material (GBCM); in 37% (7/19), it was given for a different risk factor. In those premedicated for a previous allergic-like reaction to GBCM of known severity (n = 9), the breakthrough reaction severity was the same as index reaction severity in 56% (5/9), less severe in 11% (1/9), and of greater severity in 33% (3/9). Two severe breakthrough reactions occurred; both were in subjects premedicated for risk factors other than a previous GBCM reaction. No subjects died. Five subjects were reexposed to GBCM a total of 9 times; no repeat breakthrough reactions occurred. Breakthrough reactions were more severe than nonbreakthrough reactions (P = 0.046), but the level of significance was borderline. CONCLUSION: Premedication does not eliminate severe reactions to gadobenate dimeglumine. Breakthrough reactions to gadobenate dimeglumine can be of greater severity than index reactions. PMID- 29470194 TI - Magnetization Transfer Ratio in Peripheral Nerve Tissue: Does It Depend on Age or Location? AB - BACKGROUND AND PURPOSE: Magnetization transfer contrast imaging provides indirect information on the concentration of "bound" water protons and their interactions with "free" water molecules. The purpose of this study is to analyze location- and age-dependent changes in the magnetization transfer ratio (MTR) of lower extremity nerves. MATERIALS AND METHODS: Ten younger (20-32 years) and 5 older (50-63 years) healthy volunteers underwent magnetization transfer contrast imaging at 3 Tesla Two 3-dimensional gradient echo sequences with and without an off-resonance saturation pulse (repetition time: 58 milliseconds; echo time: 2.46 milliseconds; band width: 530 Hz/Px; flip angle: alpha = 7 degrees ) were acquired at 3 different locations covering the proximal thigh to the distal lower leg in the group of younger volunteers and at 2 different locations covering the proximal to distal thigh in the group of older volunteers. Sciatic and tibial nerve regions of interest (ROIs) were manually drawn and additional ROIs were placed in predetermined muscles. Magnetization transfer ratios were extracted from respective ROIs and calculated for each individual and location. RESULTS: In young volunteers, mean values of nerve and muscle MTR were not different between the proximal thigh (nerve: 20.34 +/- 0.91; muscle: 31.71 +/- 0.29), distal thigh (nerve: 19.90 +/- 0.98; P = 0.76; muscle: 31.53 +/- 0.69; P = 0.87), and lower leg (nerve: 20.82 +/- 1.07; P = 0.73; muscle: 32.44 +/- 1.11; P = 0.51). An age dependent decrease of sciatic nerve MTR was observed in the group of older volunteers (16.95 +/- 1.2) compared with the group of younger volunteers (20.12 +/- 0.65; P = 0.019). Differences in muscle MTR were not significant between older (31.01 +/- 0.49) and younger (31.62 +/- 0.37; P = 0.20) volunteers. CONCLUSION: The MTR of lower extremity nerves shows no proximal-to-distal gradient in young healthy volunteers but decreases with age. For future studies using MTR in peripheral nerve disorders, these findings suggest that referencing magnetization transfer contrast values in terms of age, but not anatomical nerve location is required.

AB - Editor's note: From its first issue in 1900 through to the present day, AJN has unparalleled archives detailing nurses' work and lives over more than a century. These articles not only chronicle nursing's growth as a profession within the context of the events of the day, but also reveal prevailing societal attitudes about women, health care, and human rights. Today's nursing school curricula rarely include nursing's history, but it's a history worth knowing. To this end, From the AJN Archives highlights articles selected to fit today's topics and times.This excerpt, from an article in the June 1915 issue, illustrates the ways in which nurses of that era were intimately involved in feeding their patients. Cora McCabe Sargent, a nurse who wrote several nutrition-related articles for AJN, writes that "while it is not at all essential that a good cook understand nursing the sick, it is most important that a good nurse have a certain, practical knowledge of cooking." Here she extols the value of a meticulously made cream sauce in tempting "the capricious appetite of the sick." (To read the full article, go to http://links.lww.com/AJN/A108.)Today's nurses are still concerned with patient nutrition, often addressing the nutritional needs of a community or a particular patient population in addition to those of individual patients. For tools and interventions that can help nurses to support good nutrition later in life, see "Malnutrition in Older Adults" in this month's issue.

AB - Editor's note: On July 26, 2017, Alex Wubbels, the charge nurse on the burn unit at the University of Utah Hospital in Salt Lake City, was arrested for refusing to allow a police officer to draw blood from an unconscious patient in her care. Her arrest, during which she was forcefully placed in handcuffs and dragged out of the hospital, was documented on body camera video and drew national attention. We asked our ethical and legal contributing editors to provide some insight on the issues of this case. PMID- 29470218 TI - Expanding RN Scope of Practice to Include Lumbar Puncture. AB - : The competing demands of caring for high-acuity patients, reducing health care costs, and improving access to specialty care are complex challenges facing all health care providers. One approach-empowering nurses to expand their scope of practice-has been successfully employed for two decades by the nurse and physician leadership of a neurology department in an urban academic medical center. This article discusses the department's implementation of a quality improvement initiative to enhance access to neurology services in an ambulatory clinic by extending nursing practice to include lumbar puncture. Outcomes data from 2005 to 2016 demonstrate that through the department's comprehensive instructional program, RNs have competently and safely acquired new skills that have led to an expansion of their traditional roles, improved patient access to specialty care, and reduced costs.

AB - : This article is part of a series, Supporting Family Caregivers: No Longer Home Alone, published in collaboration with the AARP Public Policy Institute. Results of focus groups, conducted as part of the AARP Public Policy Institute's No Longer Home Alone video project, supported evidence that family caregivers aren't given the information they need to manage the complex care regimens of family members. This series of articles and accompanying videos aims to help nurses provide caregivers with the tools they need to manage their family member's health care at home.The articles in this new installment of the series provide simple and useful instructions that nurses should reinforce with family caregivers who perform wound care tasks. Each article also includes an informational tear sheet-Information for Family Caregivers-that contains links to instructional videos. To use this series, nurses should read the article first, so they understand how best to help family caregivers, and then encourage caregivers to watch the videos and ask questions.

PMID- 29470227 TI - Hospitalized Patients With and Without Hemodialysis Have Markedly Different Vancomycin Pharmacokinetics: A Population Pharmacokinetic Model-Based Analysis. AB - BACKGROUND: Despite being in clinical use for about 6 decades, vancomycin dosing remains perplexing and complex. METHODS: A population pharmacokinetic modeling and simulation approach was used to evaluate the efficiency of the current nomogram-based dosing of vancomycin. Serum vancomycin concentrations were obtained as a part of routine therapeutic drug monitoring from two 500-bed academic medical centers. A population pharmacokinetic model was first built using these therapeutic drug monitoring data. Population pharmacokinetic modeling was conducted using NONMEM (7.2 and 7.3). The forward addition-backward elimination approach was used to test the covariate effects. Appropriate numerical and visual criteria were used as model diagnostics for checking model appropriateness and model qualification. The current nomogram efficiency was evaluated by determining the percentage of subjects in the therapeutic range (10 20 mg/L). RESULTS: A 2-compartment model with between-subject variability on clearance (CL), central volume of distribution (Vc), and peripheral volume of distribution best fit the data. Blood urea nitrogen, age, creatinine clearance, and hemodialysis status were significant covariates on clearance. Hemodialysis status was a significant covariate on Vc and peripheral volume of distribution. In the final model, creatinine clearance was retained as a covariate on CL whereas hemodialysis status was retained as covariate on both CL and Vc. Using Monte Carlo simulations, the current nomogram was optimized by the addition of a loading dose and reducing the maintenance doses. The current nomogram is suboptimal. Optimization of the nomogram resulted in >40% subjects consistently being in the therapeutic range at troughs collected after the first 6 doses. CONCLUSIONS: CL and Vc differ markedly between patients undergoing hemodialysis and those not undergoing hemodialysis. Dosing nomogram based on these covariate relationships may potentially help in accurate dosing of vancomycin. PMID- 29470228 TI - Amiodarone Rifampicin Drug-Drug Interaction Management With Therapeutic Drug Monitoring. AB - The authors present a case of a 69-year-old man with arrhythmogenic right ventricular cardiomyopathy controlled with amiodarone and an infected orthopedic prosthesis requiring treatment with rifampicin. This combination involves a pharmacokinetic drug-drug interaction leading to subtherapeutic drug concentrations of amiodarone and its active metabolite. The long half-life of amiodarone and its active metabolite in combination with the late onset and offset of cytochrome P4503A (CYP3A4) induction by rifampicin makes this a challenging drug-drug interaction to cope with in clinical practice. Before, during, and after rifampicin treatment, the serum concentrations of amiodarone and its active metabolite were measured and the amiodarone dose was adjusted accordingly. The amiodarone dose required to maintain effective concentrations was 450% of the initial dose. The drug-drug interaction between amiodarone and rifampicin is relevant, both clinically and pharmacokinetically, and can be managed by dose adjustments of amiodarone based on serum concentrations. PMID- 29470229 TI - Three-Year Changes in Physical Activity and Subsequent Loss of Ability to Walk 400 m in Older Adults: The InCHIANTI Study. AB - We examined the associations of maintaining or increasing physical activity (PA) for a 3-yr follow-up with subsequent incident inability to complete the 400-m walk test (i.e., mobility disability) for 6 yrs of follow-up in older adults. This study included 421 participants 65 yrs and older. The 400-m walk test was assessed at baseline and at 3-, 6-, and 9-yr follow-up. Physical activity was self-reported through a 6-point rating scale at baseline and 3-yr follow-up. Three-year cumulative PA (i.e., average at baseline and at 3-yr follow-up) and its changes (i.e., from baseline to 3-yr follow-up) were linked to subsequent incidence of mobility disability for 6 yrs of follow-up (i.e., from 3- to 9-yr follow-up), after adjustment for potential covariates. After the 3-yr period, incidence of mobility disability for the subsequent 6 yrs of follow-up occurred in 129 participants. The odds ratio (95% confidence interval) of incident mobility disability associated with 1-category increase in cumulative PA was 0.63 (0.41-0.97, P = 0.036). The odds ratio (95% confidence interval) of incident mobility disability associated with 1-category increase in changes in PA was 0.56 (0.38-0.84, P = 0.005). Hence, maintaining or increasing PA levels is associated with a reduced risk of mobility disability among older adults. PMID- 29470230 TI - Patients With Limited Health Literacy Have Similar Preferences but Different Perceptions in Surgical Decision-making for Carpal Tunnel Release. AB - BACKGROUND: Health literacy is the ability to obtain, process, and understand health information needed to make appropriate health decisions. The proper comprehension by patients regarding a given disease, its treatment, and the physician's instructions plays an important role in shared decision-making. Studies have disagreed over the degree to which differences in health literacy affect patients' preferences for shared decision-making; we therefore sought to evaluate this in the context of shared decision-making about carpal tunnel release. QUESTIONS/PURPOSES: (1) Do patients with limited health literacy have different preferences of shared decision-making for carpal tunnel release than those with greater levels of health literacy? (2) How do patients with limited health literacy retrospectively perceive their role in shared decision-making after carpal tunnel release? METHODS: Over a 32-month period, one surgeon surgically treated 149 patients for carpal tunnel syndrome. Patients were eligible if they had cognitive and language function to provide informed consent and complete a self-reported questionnaire and were not eligible if they had nerve entrapment other than carpal tunnel release or had workers compensation issues; based on those, 140 (94%) were approached for study. Of those, seven (5%) were lost to followup before 6 months, leaving 133 for analysis here. Their mean age was 55 years (range, 31-76 years), and 83% (111 of 133) were women. Thirty three percent (44 of 133) of patients had less than a high school education. Health literacy was measured according to the Newest Vital Sign during the initial visit, and a score of <= 3 was considered limited health literacy. Forty four percent of patients had limited health literacy. The Control Preferences Scale was used for patients to indicate their preferred role in surgical decision making preoperatively and to assess their perceived level of involvement postoperatively. Bivariate and multivariable analyses were performed to determine whether patients' clinical, demographic, and health literacy factors accounted for the preoperative preferences and postoperative assessments of their role in shared decision-making. A total of 133 patients would provide 94% power for a medium effect size for linear regression with five main predictors. RESULTS: We found no differences between patients with lower levels of health literacy and those with greater health literacy in terms of preferences of shared decision making for carpal tunnel release (3.0 +/- 1.6 versus 2.7 +/- 1.4; mean difference, 0.3; 95% confidence interval, -0.2 to 0.8; p = 0.25). A history of surgical procedures (coefficient = -0.32, p < 0.01) and a lower Disabilities of the Arm, Shoulder and Hand score (coefficient = 0.17, p = 0.02) were independently associated with a preference for an active role in shared decision making. However, patients with limited health literacy (coefficient = -0.31, p = 0.01) and an absence of a caregiver (coefficient = -0.28, p = 0.03) perceived a more passive role in actual decision-making. CONCLUSIONS: Physicians should be aware of the discrepancy between preferences and perceptions of shared decision making among patients with limited health literacy, and physicians should consider providing a decision aid tailored to basic levels of health literacy to help patients achieve their preferred role in decision-making.

PMID- 29470232 TI - Intraoperative Extracorporeal Irradiation and Frozen Treatment on Tumor-bearing Autografts Show Equivalent Outcomes for Biologic Reconstruction. AB - BACKGROUND: Immediately recycling the resected bone segment in a biologic limb salvage reconstruction is an option after wide resection of bone. Intraoperative extracorporeal irradiation and freezing are the two major tumor-killing techniques applied on the fresh tumor-bearing autografts. However, graft-derived tumor recurrence and complications are concerns affecting graft survival. QUESTIONS/PURPOSES: We therefore asked: (1) Is there a difference in the proportion of patients achieving union by 18 months after surgery between the groups with extracorporeal-irradiated autografts and frozen-treated autografts? (2) Is there any difference in the frequency of graft-related complications for patients receiving either an extracorporeal-irradiated or a frozen-treated autograft? (3) Is there a difference between the techniques in terms of graft derived recurrence? (4) Are there differences in failure-free grafts, and limb and overall survivorship between autografts treated by extracorporeal irradiation or by freezing? METHODS: During the study period we treated a total of 333 patients with high-grade osteosarcoma. One hundred sixty-nine patients were excluded. Overall, 79 of the enrolled 164 patients received recycled autografts treated with extracorporeal irradiation whereas the other 85 received frozen treated autografts. The mean followup was 82 +/- 54 months for the extracorporeal irradiation group and 70 +/- 25 months for the frozen autograft group, and one patient was lost to followup. Complications and graft failure (revision required for primary graft removal) were characterized by adapting the International Society of Limb Society (ISOLS) system modified for inclusion of biologic and expandable reconstruction. The primary study endpoints were the proportion of patients in each group who achieved radiographic union, and had an ISOLS grade of fair or good host graft fusion at 6, 9, 12, and 18 months after surgery. Five year survival data for graft failure and limb amputation were analyzed by a cumulative incidence function regression model whereas the Kaplan-Meier function was used to test the 5-year overall survival rate between the two techniques. RESULTS: With the numbers available, no differences were found in the accumulated proportion of patients achieving union between the groups at 6, 9, 12, and 18 months. Radiographic evaluation did not show differences in the average scores of compared criteria. However in the subchondral bone subcriterion, more patients receiving frozen-treated autografts had higher scores (p = 0.03). Complications leading to a second surgery were not different between extracorporeal irradiation and frozen autografts in aspects of soft tissue failure (Type 1B), nonunion (Type 2B), structural failure (Type 3A and Type 3B), or infection (Type 4A and Type 4B). No graft-originating tumor recurrence was found and there was no difference in Type 5A tumor progression originating from soft tissue in the groups (odds ratio, 0.8; 95% CI, 0.3-2.1; p = 0.7). Neither group showed a difference in the cumulative incidence for graft failure and limb amputation. Five-year overall survival rates were 83% and 84% (p = 0.69) for extracorporeal-irradiated and frozen autografts respectively. A decrease in survivorship was seen at 50 to 100 months after surgery for the extracorporeal irradiation group. CONCLUSION: We segregated the ISOLS criteria evaluating the graft-mediated tumor progression into host- or graft-derived complications (Types 5B and 5C) in this study. With the available data, there was no difference in the incidence of tumor recurrence derived from irradiation- or frozen-treated autografts. Ongoing evaluations comparing 10-year survivorship for both groups will be helpful to elucidate the possible difference found after 100 months. LEVEL OF EVIDENCE LEVEL: III, therapeutic study. PMID- 29470233 TI - Can a Nomogram Help to Predict the Overall and Cancer-specific Survival of Patients With Chondrosarcoma? AB - BACKGROUND: Many factors have been reported to be associated with the prognosis of patients with chondrosarcoma, but clinicians have few tools to estimate precisely an individual patient's likelihood of surviving the illness. We therefore sought to develop effective nomograms to better estimate the survival of patients with chondrosarcoma. QUESTIONS/PURPOSES: (1) Which clinicopathologic features are independent prognostic factors for patients with chondrosarcoma? (2) Can we develop a nomogram to predict 3- and 5-year overall and cancer-specific survival of individual patients with chondrosarcoma based on personalized information? METHODS: We collected information on patients diagnosed with chondrosarcoma between 1988 and 2011 from the Surveillance, Epidemiology, and End Results (SEER) database. The SEER database consists of 18 cancer registries and covers approximately 30% of the total United States population. One thousand thirty-four adult patients with grade II or III chondrosarcoma were included in the cohort (patients with grade I chondrosarcoma were not evaluated in this study), while 327 patients were excluded from the study owing to missing data regarding tumor size or metastasis. Nine hundred nineteen patients (89%) in the cohort had complete followup for at least 1 year. The X-tile program was used to determine optimal cutoff points. Univariate and multivariate analyses were applied to identify independent factors that were further included in the nomograms predicting 3- and 5-year overall survival and cancer-specific survival. Records of 1034 patients were collected and randomly divided into training (n = 517) and validation (n = 517) cohorts. The nomograms were developed based on training cohort. Data for the training cohort were obtained for internal validation of the nomograms, whereas data for the validation cohort were obtained for external validation of the nomograms. Bootstrapped validation, which used a resample with 500 iterations, was applied to validate the nomograms internally and externally. RESULTS: Six independent prognostic factors for overall survival and six for cancer-specific survival were identified and incorporated to construct nomograms for 3- and 5-year overall and cancer-specific survival. These nomograms can easily be used by providers in the office to estimate a patient's prognosis; the only clinical details a provider needs to use these nomograms effectively are age, histologic subtype, tumor grade, whether surgery was performed, tumor size, and the presence or absence of metastases. Internal and external calibration plots for the probability of 3- and 5-year overall survival and cancer-specific survival showed good agreement between nomogram prediction and observed outcomes. The concordance indices (C-indices) for internal validation of overall survival and cancer-specific survival prediction were 0.803 and 0.829, respectively, whereas the C-indices for external validation were 0.753 and 0.759, respectively. CONCLUSIONS: We were able to develop effective nomograms to predict overall survival and cancer-specific survival for patients with chondrosarcoma; these nomograms require only basic information, which should be available to all providers in the office setting. If these observations can be validated in different registries or databases, the nomograms can assist clinicians in counseling patients regarding therapeutic choices. LEVEL OF EVIDENCE: Level III, prognostic study. PMID- 29470234 TI - Incidence of Neuraxial Abnormalities Is Approximately 8% Among Patients With Adolescent Idiopathic Scoliosis: A Meta-analysis. AB - BACKGROUND: Several studies have sought to address the role of routine preoperative MRI in patients with adolescent idiopathic scoliosis (AIS) undergoing deformity correction. Despite similar results regarding the prevalence of neuraxial anomalies detected on MRI, published conclusions conflict and give opposing recommendations. Lack of consensus has led to important variations in use of MRI before spinal surgery for patients with AIS. QUESTIONS/PURPOSES: This systematic review and meta-analysis of studies about patients with AIS evaluated (1) the overall proportion of neuraxial abnormalities; (2) the patient factors and curve characteristics that may be associated with abnormalities; and (3) the proportion of patients who underwent neurosurgical intervention before scoliosis surgery and the kinds of neuraxial lesions that were identified. METHODS: We performed a search of four electronic databases (PubMed, EMBASE, CINAHL Plus, and SCOPUS) utilizing search terms related to routine MRI and AIS, yielding 206 articles. Studies included had at least 20 participants, patients with ages 11 to 21 years, and a Methodological Index for Non-Randomized Studies (MINORS) study quality score of 8 and 16 points for noncomparative and comparative studies, respectively. Non-English manuscripts, animal studies, and those that did not include patients with AIS solely were excluded. Eighteen articles with 4746 patients were included for analysis of the overall proportion of neuraxial abnormalities, 12 articles with 3028 patients for analysis by sex, eight articles with 1603 patients for right main thoracic curve, eight articles with 665 patients for a left main thoracic curve, and 13 articles with 3063 patients and 230 (7.5%) abnormalities for number of neurosurgical interventions before scoliosis correction. The mean MINORS score for studies included was 14 (range, 10-20). Each study was analyzed for the proportion of patients identified with neuraxial abnormalities and associations with specific demographics. We determined the proportion of patients who underwent surgical interventions before scoliosis surgery as well as the types of neuraxial lesions identified. The articles were assessed for heterogeneity and publication bias. Because all groups were determined to be heterogeneous, a random-effects model was used for each group in this meta-analysis; with this analysis, an overlap of 95% confidence intervals suggests no difference at the p < 0.05 level, but this analytic approach does not provide p values. RESULTS: The pooled proportion of neuraxial abnormalities detected on MRI was 8% (95% confidence interval [CI], 6%-12%). With the numbers available, we found no difference in the proportion of male and female patients with neuraxial abnormalities (18% [95% CI, 11%-29%] versus 9% [95% CI, 6%-12%], respectively). Likewise, there was no difference in the proportion of pooled neuraxial abnormalities in right and left curves (9% [95% CI, 6%-14%] versus 15% [95% CI, 5%-35%], respectively). In the subset of abnormalities analyzed for number of neurosurgical interventions before scoliosis correction, the pooled proportion showed that 33% (95% CI, 24%-43%) underwent neurosurgical intervention before deformity correction. The most common abnormalities of the 367 found on MRI were syringomyelia in 127 patients (35%), Arnold-Chiari Type 1 malformation with syrinx in 103 patients (28%), and isolated Arnold-Chiari Type 1 malformation in 91 patients (25%). CONCLUSIONS: The proportion of patients with AIS who have neuraxial abnormalities is high (8%) and a large number undergo surgical intervention before scoliosis reconstruction. We did not find any particular demographic variables that indicated an increased risk of abnormality. Clinicians should consider advanced imaging before surgical intervention in the treatment of a patient with an idiopathic diagnosis. Preventable variables need to be identified by future studies to establish a better working treatment protocol for these patients. LEVEL OF EVIDENCE: Level III, diagnostic study. PMID- 29470235 TI - Is Climate Associated With Revision for Prosthetic Joint Infection After Primary TKA? AB - BACKGROUND: Climate factors have been shown to be associated with spontaneous musculoskeletal and some surgical site infections with increased rates of infection during warmer periods. To date, little research has been performed to determine if this phenomenon is associated with differences in the risk of revision for prosthetic joint infection (PJI) in primary TKA. QUESTIONS/PURPOSES: (1) Does the rate of revision for early PJI within the first year after primary TKA differ between tropical and nontropical regions? (2) Is there a seasonal variation in the rate of revision for PJI? (3) Is the geographic and seasonal variation (if present) associated with the sex, age, and/or American Society of Anesthesiologists (ASA) grade of the patient? METHODS: All 219,983 primary TKAs performed for osteoarthritis over a 5-year period (2011-2015) in the Australian Orthopaedic Association National Joint Replacement Registry were examined based on the month of the primary procedure to determine the rate of revision for PJI within 12 months. The data were analyzed to determine the differences in the risk of revision for PJI based on geographic region and season of the primary procedure adjusting for sex, age, and ASA grade of the patient. RESULTS: The early revision rate for PJI was higher in the tropical compared with the nontropical region of Australia (0.73% versus 0.37%; odds ratio [OR], 1.87; 95% confidence interval [CI], 1.44-2.42; p < 0.001). The tropical region of Australia demonstrated a seasonal variation in the rate of revision for PJI with a higher rate during the warmer monsoon wet season of summer and fall (summer/fall 0.98% versus winter/spring 0.51%; OR, 1.88; 95% CI, 1.12-3.16; p = 0.02). A seasonal variation was not seen in the nontropical region (OR, 1.03; 95% CI, 0.90-1.19; p = 0.64). The regional and seasonal changes were independent of sex, age, and ASA grade. CONCLUSIONS: Climate factors are associated with the risk of early revision for PJI in patients undergoing primary TKA with rates of such revisions approximately double in tropical regions compared with nontropical regions. Additionally, tropical regions demonstrate a seasonal variation with the risk of PJI doubling during the warmer, monsoonal wet season of summer and fall. These findings should be confirmed in further studies that can better control for possible confounding variables. The mechanism for this phenomenon is not clear, and further research into this subject is also indicated. LEVEL OF EVIDENCE: Level III, therapeutic study. PMID- 29470236 TI - Is the Lesser Trochanter Profile a Reliable Means of Restoring Anatomic Rotation After Femur Fracture Fixation? AB - BACKGROUND: Restoring normal femoral rotation is an important consideration when managing femur fractures. Femoral malrotation after fixation is common and several preventive techniques have been described. Use of the lesser trochanter profile is a simple method to prevent malrotation, because the profile changes with femoral rotation, but the accuracy of this method is unclear. QUESTIONS/PURPOSES: The purposes of this study were (1) to report the rotational profiles of uninjured femora in an adult population; and (2) to determine if the lesser trochanter profile was associated with variability in femoral rotation. METHODS: One hundred fifty-five consecutive patients (72% female and 28% male) with a mean age of 32 years (range, 12-56 years) with a CT scanogram were retrospectively evaluated. Patients were included if CT scanograms had adequate cuts of the proximal and distal femur. Patients were excluded if they had prior hip/femur surgery or anatomic abnormalities of the proximal femur. CT scanogram measurements of femoral rotation were compared with the lesser trochanter profile (distance from the tip of the lesser trochanter to the medial cortex of the femur) measured on weightbearing AP radiographs. These measurements were made by a single fellowship-trained orthopaedic surgeon and repeated for intraobserver reliability testing. Presence of rotational differences based on sex and laterality was assessed and correlation of the difference in lesser trochanter profile to the difference in femoral rotation was determined using a coefficient of determination (r). RESULTS: The mean femoral rotation was 10.9 degrees (SD +/ 8.8 degrees ) of anteversion. Mean right femoral rotation was 11.0 degrees (SD +/- 8.9 degrees ) and mean left femoral rotation was 10.7 degrees (SD +/- 8.7 degrees ) with a mean difference of 0.3 degrees (95% confidence interval [CI], 1.7 degrees to 2.3 degrees ; p = 0.76). Males had a mean rotation of 9.4 degrees (SD +/- 7.7 degrees ) and females had a mean rotation of 11.5 degrees (SD +/- 9.1 degrees ) with a mean difference of 2.1 degrees (95% CI, -0.1 degrees to 4.3 degrees ; p = 0.06). Mean lesser trochanter profile was 6.6 mm (SD +/- 4.0 mm). Mean right lesser trochanter profile was 6.6 mm (SD +/- 3.9 mm) and mean left lesser trochanter profile was 6.5 mm (SD +/- 4.0 mm) with a mean difference of 0.1 mm (-0.8 mm to 1.0 mm, p = 0.86). The lesser trochanter profile varied between the sexes; males had a mean of 8.3 mm (SD +/- 3.4), and females had a mean of 5.9 mm (SD +/- 4.0). The mean difference between sexes was 2.5 mm (1.5 3.4 mm; p < 0.001). The magnitude of the lesser trochanter profile measurement and degree of femoral rotation were positively correlated such that increasing measures of the lesser trochanter profile were associated with increasing amounts of femoral anteversion. The lesser trochanter profile was associated with femoral version in a linear regression model (r = 0.64; p < 0.001). Thus, 64% of the difference in femoral rotation can be explained by the difference in the lesser trochanter profile. Intraobserver reliability for both the femoral version and lesser trochanter profile was noted to be excellent with intraclass correlation coefficients of 0.94 and 0.95, respectively. CONCLUSIONS: This study helps define the normal femoral rotation profile among adults without femoral injury or bone deformity and demonstrated no rotational differences between sexes. The lesser trochanter profile was found to be positively associated with femoral rotation. Increasing and decreasing lesser trochanter profile measurements are associated with increasing and decreasing amounts of femoral rotation, respectively. CLINICAL RELEVANCE: The lesser trochanter profile can determine the position of the femur in both anteversion and retroversion, supporting its use as a method to restore preinjury femoral rotation after fracture fixation. Although some variability in the rotation between sides may exist, matching the lesser trochanter profile between injured and uninjured femora can help reestablish native rotation. PMID- 29470237 TI - Primary Shoulder Hemiarthroplasty: What Can Be Learned From 359 Cases That Were Surgically Revised? AB - BACKGROUND: Primary shoulder hemiarthroplasty is used to address a range of glenohumeral disorders, including fracture, arthritis, avascular necrosis, and capsulorrhaphy arthropathy; some patients with hemiarthroplasties undergo revision surgery for persistent pain or residual shoulder dysfunction. The literature does not clarify the features of the hemiarthroplasties having repeat surgery in a way that can guide surgeons' efforts to minimize the need for revision. To help address this gap, we analyzed the characteristics of patients from our region for whom we performed surgical revision of a prior humeral hemiarthroplasty QUESTIONS/PURPOSES: (1) What are the common characteristics of shoulder hemiarthroplasties having a revision? (2) What are the common characteristics of the subset of revised shoulder hemiarthroplasties that were performed for fracture? (3) What are characteristics of the subset of all revised hemiarthroplasties that were associated with glenoid bone erosion? METHODS: Data for 983 patients for whom we performed a surgical revision of any type of shoulder arthroplasty between January 1991 and January 2017 were identified in our longitudinally maintained institutional arthroplasty revision database. In each case, revision had been elected by shared patient and surgeon decision making after consideration of the disorder, degree of compromised comfort and function, treatment alternatives, and the risks of surgery. Of these 983 patients, 359 (37%) had a revision of a prior primary hemiarthroplasty; these patients were the subjects of this investigation. In this group of patients, we investigated the patient demographics, shoulder characteristics, prerevision radiographic findings, and findings at revision surgery. No patients were excluded. The patients having revision of primary hemiarthroplasties had severe loss of self-assessed shoulder comfort and function, with Simple Shoulder Test (SST) scores averaging 2.2 +/- 2.2 of the maximum score of 12. The majority of these patients (81%) were women. The medical records of these 359 patients were abstracted to determine the diagnosis for the index primary hemiarthroplasty, clinical characteristics before surgery, and findings at surgical revision. One hundred twelve of the arthroplasties had been performed for fracture-related diagnoses; a subgroup analysis was performed on these patients. Two hundred seventy-three of the 359 patients (76%) had plain radiographs performed within 3 months before revision surgery that were adequate for assessing the radiographic characteristics of the glenoid, humerus, humeral component, and glenohumeral relationships; a subgroup analysis was performed on these patients. The degree of glenoid erosion was measured by a single observer in accordance with established criteria: Grade 1 is no erosion, Grade 2 is erosion limited to subchondral bone, Grade 3 is moderate erosion with medialization, and Grade 4 is medialization beyond the coracoid base. Some patients were included in both of these subgroups. RESULTS: Common characteristics of the revised hemiarthroplasties included female sex (81%), rotator cuff (89 of 359; 25%) or subscapularis (81 of 359; 23%) failure, problems related to prior fracture (154 of 359; 43%), glenoid erosion 125 of 359; 35%), and component malposition (89 of 359; 25%). Hemiarthroplasties performed for fracture-related problems often were associated with tuberosity malunion or nonunion (58 of 79; 73%) and decentering of the humeral component on the glenoid surface (45 of 71; 63%). Major erosion of the bony glenoid (Grade 3 or 4) was more common in decentered hemiarthroplasties (42 of 102; 41%) than for centered hemiarthroplasties (36 of 146; 25%) (Fisher's exact p = 0.008) and more common for hemiarthroplasties positioned in valgus (28 of 50; 56%) than for those positioned in neutral or varus (40 of 188; 21%) (Fishers' exact p < 0.0001). CONCLUSIONS: These findings suggest that some revisions of primary hemiarthroplasties may be avoided by surgical techniques directed at centering the prosthetic humeral articular surface on the glenoid concavity using proper humeral component positioning and soft tissue balance, by avoiding valgus positioning of the humeral component, and by managing glenoid disorders with a primary glenohumeral arthroplasty rather than a hemiarthroplasty alone. When durable security of the subscapularis, rotator cuff, and tuberosities is in question, the surgeon may consider a reverse total shoulder arthroplasty.

PMID- 29470245 TI - Intra-Aortic Balloon Pump Use Before Left Ventricular Assist Device Implantation: Insights From the INTERMACS Registry. AB - Use of durable, continuous-flow left ventricular assist devices (LVADs) has expanded rapidly, although data are limited regarding optimization strategies before LVAD implantation. We examined current use of intra-aortic balloon pumps (IABPs) before LVAD implantation and compared outcomes of patients with IABP use to those without. We analyzed data from the Interagency Registry for Mechanical Assisted Circulatory Support (INTERMACS) on patients who underwent LVAD implantation between 2006 and 2014. We limited the analysis to patients with an admitting diagnosis of LVAD placement. The primary exposure was IABP use within 48 hours before LVAD implantation. We used propensity scores to compare 30 day postoperative outcomes to reduce treatment selection bias. Of 2,446 patients, 433 (18%) received an IABP before LVAD placement. Patients with IABP use, compared with those without, had markers of more advanced disease, including worse renal and liver function, worse right ventricular function, and use of mechanical ventilation (p < 0.05 for all comparisons). A composite outcome of post-operative right heart failure, hepatic dysfunction, renal dysfunction, or death occurred in 83 (19.2%) patients with IABP use, compared with 342 (17.1%) patients without IABP use (unadjusted hazard ratio, 1.13; 95% confidence interval, 0.89-1.44; adjusted hazard ratio, 1.02; 95% confidence interval, 0.78-1.33). IABP use before LVAD placement was common. Despite markers of higher risk in patients with IABP use, we found no significant difference in 30 day outcomes compared to those without. The results suggest that IABP use may mitigate risk of early postoperative adverse outcomes in select patients. PMID- 29470246 TI - Design and Evaluation of a Structural Reinforced Small Intestinal Submucosa Vascular Graft for Hemodialysis Access in a Porcine Model. AB - Synthetic vascular access for hemodialysis exhibits biological and mechanical material properties mismatch with the native vessels. These limitations prevent infiltration of endothelial cells and decrease grafts long-term patency, particularly in small diameter vessels. We aimed to design a curved structural reinforced small intestinal submucosa (SIS) vascular graft for hemodialysis access and to evaluate in a porcine animal model graft patency by Doppler ultrasonography, tissue remodeling by histology, and vascular wall Young's modulus after implantation by biaxial tensile test. Curved 4 mm inner diameter, 0.5 mm thickness, and 150 mm length SIS grafts were designed. Small intestinal submucosa vascular grafts were preliminary tested in vivo in a porcine animal model (n=3) constructing an arteriovenous fistula between the carotid artery and the jugular vein; GORE-TEX grafts were implanted as control. Small intestinal submucosa grafts remained patent 46 +/- 7 days against the control, 30 +/- 3 days. Histology showed thrombus formation on the lumen (80% to 100% surface area) of all explanted grafts. Small intestinal submucosa grafts exhibited neovascularization and endothelial cells alignment on the graft wall, indicating regeneration. Biaxial tensile tests demonstrated no significant differences in Young's moduli between SIS grafts (ECirc = 2.5 +/- 1.0 MPa, ELong = 5.7 +/- 2.6 MPa) and native artery (ECirc = 1.4 +/- 0.8 MPa, ELong = 5.5 +/- 1.1 MPa), indicating similar wall stiffness. This study proposes an innovative design of a tissue-engineered vascular graft for hemodialysis access that, besides its structural characteristics similar to those of current synthetic grafts, could enhance biological performance because of its composition. PMID- 29470247 TI - Hypofibrinogenemia Is Associated With Poor Outcome and Secondary Hemophagocytic Lymphohistiocytosis/Macrophage Activation Syndrome in Pediatric Severe Sepsis. AB - OBJECTIVES: Some children with sepsis exhibit a sustained hyperinflammatory response that can trigger secondary hemophagocytic lymphohistiocytosis/macrophage activation syndrome. Although hypofibrinogenemia is a shared feature of sepsis and hemophagocytic lymphohistiocytosis, there are no data about fibrinogen as a biomarker to identify children with sepsis/secondary hemophagocytic lymphohistiocytosis/macrophage activation syndrome overlap. We hypothesized that hypofibrinogenemia is associated with poor outcomes and secondary hemophagocytic lymphohistiocytosis/macrophage activation syndrome and has utility as a screening biomarker for this sepsis phenotype. DESIGN: A retrospective cohort study of patients less than or equal to 21 years treated for severe sepsis from January 2012 to December 2014. SETTING: Emergency department and PICU at a single academic children's hospital. PATIENTS: Consecutive patients with greater than or equal to one episode of hypofibrinogenemia (serum fibrinogen < 150 mg/dL) within 7 days of sepsis were compared with a random sample of patients without hypofibrinogenemia using an a priori sample size target of 190. Thirty-eight patients with hypofibrinogenemia were compared with 154 without hypofibrinogenemia. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The primary outcome was "complicated course" (composite of 28-d mortality or >= two organ failures at 7 d). Secondary outcomes were 28-day mortality and fulfillment of diagnostic criteria for secondary hemophagocytic lymphohistiocytosis/macrophage activation syndrome. We used Wilcoxon rank-sum, Fisher exact test, and multivariable logistic regression to compare patients with versus without hypofibrinogenemia. Patients with hypofibrinogenemia were more likely to have a complicated course (73.7% vs 29.2%; p < 0.001), 28-day mortality (26.3% vs 7.1%, p = 0.002), and meet diagnostic criteria for secondary hemophagocytic lymphohistiocytosis/macrophage activation syndrome (21.1% vs 1.3%; p < 0.001). After controlling for confounders, hypofibrinogenemia remained associated with complicated course (adjusted odds ratio, 8.8; 95% CI, 3.5-22.4), mortality (adjusted odds ratio, 6.0; 95% CI, 2.0-18.1), and secondary hemophagocytic lymphohistiocytosis/macrophage activation syndrome (adjusted odds ratio, 27.6; 95% CI, 4.4-173). CONCLUSIONS: Hypofibrinogenemia was independently associated with poor outcome and secondary hemophagocytic lymphohistiocytosis/macrophage activation syndrome in pediatric sepsis. Measurement of fibrinogen may provide a pragmatic biomarker to identify children with possible sepsis/secondary hemophagocytic lymphohistiocytosis/macrophage activation syndrome overlap for whom further diagnostic testing and consideration of adjunctive immunomodulatory therapies should be considered. PMID- 29470248 TI - Role of cardiovascular imaging in cardiac resynchronization therapy: a literature review. AB - : Cardiac resynchronization therapy (CRT) is an established treatment in patients with symptomatic drug-refractory heart failure and broad QRS complex on the surface ECG. Despite the presence of either mechanical dyssynchrony or viable myocardium at the site where delivering left ventricular pacing being necessary conditions for a successful CRT, their direct assessment by techniques of cardiovascular imaging, though feasible, is not recommended in clinical practice by the current guidelines. Indeed, even though there is growing body of data providing evidence of the additional value of an image-based approach as compared with routine approach in improving response to CRT, these results should be confirmed in prospective and large multicentre trials before their impact on CRT guidelines is considered. PMID- 29470249 TI - Elevated serum uric acid affects myocardial reperfusion and infarct size in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention. AB - AIMS: Elevated serum uric acid (eSUA) was associated with unfavorable outcome in patients with ST-segment elevation myocardial infarction (STEMI). However, the effect of eSUA on myocardial reperfusion injury and infarct size has been poorly investigated. Our aim was to correlate eSUA with infarct size, infarct size shrinkage, myocardial reperfusion grade and long-term mortality in STEMI patients undergoing primary percutaneous coronary intervention. METHODS: We performed a post-hoc patients-level analysis of two randomized controlled trials, testing strategies for myocardial ischemia/reperfusion injury protection. Each patient underwent acute (3-5 days) and follow-up (4-6 months) cardiac magnetic resonance. Infarct size and infarct size shrinkage were outcomes of interest. We assessed T2 weighted edema, myocardial blush grade (MBG), corrected Thrombolysis in myocardial infarction Frame Count, ST-segment resolution and long-term all-cause mortality. RESULTS: A total of 101 (86.1% anterior) STEMI patients were included; eSUA was found in 16 (15.8%) patients. Infarct size was larger in eSUA compared with non-eSUA patients (42.3 +/- 22 vs. 29.1 +/- 15 ml, P = 0.008). After adjusting for covariates, infarct size was 10.3 ml (95% confidence interval 1.2 19.3 ml, P = 0.001) larger in eSUA. Among patients with anterior myocardial infarction the difference in delayed enhancement between groups was maintained (respectively, 42.3 +/- 22.4 vs. 29.9 +/- 15.4 ml, P = 0.015). Infarct size shrinkage was similar between the groups. Compared with non-eSUA, eSUA patients had larger T2-weighted edema (53.8 vs. 41.2 ml, P = 0.031) and less favorable MBG (MBG < 2: 44.4 vs. 13.6%, P = 0.045). Corrected Thrombolysis in myocardial infarction Frame Count and ST-segment resolution did not significantly differ between the groups. At a median follow-up of 7.3 years, all-cause mortality was higher in the eSUA group (18.8 vs. 2.4%, P = 0.028). CONCLUSION: eSUA may affect myocardial reperfusion in patients with STEMI undergoing percutaneous coronary intervention and is associated with larger infarct size and higher long-term mortality. PMID- 29470250 TI - Clinically oriented device programming in bradycardia patients: part 1 (sinus node disease). Proposals from AIAC (Italian Association of Arrhythmology and Cardiac Pacing). AB - : Modern pacemakers have an increasing number of programable parameters and specific algorithms designed to optimize pacing therapy in relation to the individual characteristics of patients. When choosing the most appropriate pacemaker type and programing, the following variables must be taken into account: the type of bradyarrhythmia at the time of pacemaker implantation; the cardiac chamber requiring pacing, and the percentage of pacing actually needed to correct the rhythm disorder; the possible association of multiple rhythm disturbances and conduction diseases; the evolution of conduction disorders during follow-up. The goals of device programing are to preserve or restore the heart rate response to metabolic and hemodynamic demands; to maintain physiological conduction; to maximize device longevity; to detect, prevent, and treat atrial arrhythmia. In patients with sinus node disease, the optimal pacing mode is DDDR. Based on all the available evidence, in this setting, we consider appropriate the activation of the following algorithms: rate responsive function in patients with chronotropic incompetence; algorithms to maximize intrinsic atrioventricular conduction in the absence of atrioventricular blocks; mode switch algorithms; algorithms for autoadaptive management of the atrial pacing output; algorithms for the prevention and treatment of atrial tachyarrhythmias in the subgroup of patients with atrial tachyarrhythmias/atrial fibrillation. The purpose of this two-part consensus document is to provide specific suggestions (based on an extensive literature review) on appropriate pacemaker setting in relation to patients' clinical features. PMID- 29470251 TI - Clinically oriented device programming in bradycardia patients: part 2 (atrioventricular blocks and neurally mediated syncope). Proposals from AIAC (Italian Association of Arrhythmology and Cardiac Pacing). AB - : The purpose of this two-part consensus document is to provide specific suggestions (based on an extensive literature review) on appropriate pacemaker setting in relation to patients' clinical features. In part 2, criteria for pacemaker choice and programming in atrioventricular blocks and neurally mediate syncope are proposed. The atrioventricular blocks can be paroxysmal or persistent, isolated or associated with sinus node disease. Neurally mediated syncope can be related to carotid sinus syndrome or cardioinhibitory vasovagal syncope. In sinus rhythm, with persistent atrioventricular block, we considered appropriate the activation of mode-switch algorithms, and algorithms for auto adaptive management of the ventricular pacing output. If the atrioventricular block is paroxysmal, in addition to algorithms mentioned above, algorithms to maximize intrinsic atrioventricular conduction should be activated. When sinus node disease is associated with atrioventricular block, the activation of rate responsive function in patients with chronotropic incompetence is appropriate. In permanent atrial fibrillation with atrioventricular block, algorithms for auto adaptive management of the ventricular pacing output should be activated. If the atrioventricular block is persistent, the activation of rate-responsive function is appropriate. In carotid sinus syndrome, adequate rate hysteresis should be programmed. In vasovagal syncope, specialized sensing and pacing algorithms designed for reflex syncope prevention should be activated. PMID- 29470252 TI - Multi and extensively drug-resistant pulmonary tuberculosis: advances in diagnosis and management. AB - PURPOSE OF REVIEW: Multidrug-resistant (MDR) tuberculosis (TB) and extensively drug-resistant (XDR)-TB epidemics are key obstacles towards TB control and elimination. RECENT FINDINGS: Diagnosis of MDR/XDR-TB is difficult and requires several weeks. New diagnostic tools are being tested and proposed allowing for shorter time to diagnosis and reduced delays in starting an adequate treatment regimen. MDR/XDR-TB treatment strategies are currently on an evolving stage. New shortened treatments based on the recommended 'Bangladesh regimen' or on the newer anti-TB drugs, delamanid and bedaquiline may represent part of the future scenario. In addition, more information on safety and efficacy of delamanid and bedaquiline has been published, allowing to better position these drugs. Recent information on treatment regimens for the paediatric age, with or without delamanid or bedaquiline, has become available. This is of great help in designing safer and more efficacious regimens for the treatment of MDR/XDR-TB in children and adolescents. SUMMARY: The accessibility, sustainability and scale-up of new diagnostic technologies are lagging behind and more efforts are needed. In addition, we need high-quality information on safety and efficacy of various combinations of drugs to obtain the best possible regimens to treat the largest possible proportion of patients. PMID- 29470254 TI - How can we improve clinical research in pneumonia? AB - PURPOSE OF REVIEW: The primary challenges in the field of clinical research include a lack of support within existing infrastructure, insufficient number of clinical research training programs and a paucity of qualified mentors. Most medical centers offer infrastructure support for investigators working with industry sponsors or government-funded clinical trials, yet there are a significant amount of clinical studies performed in the field of pneumonia which are observational studies. For this type of research, which is frequently unfunded, support is usually lacking. RECENT FINDINGS: In an attempt to optimize clinical research in pneumonia, at the University of Louisville, we developed a clinical research coordinating center (CRCC). The center manages clinical studies in the field of respiratory infections, with the primary focus being pneumonia. Other activities of the CRCC include the organization of an annual clinical research training course for physicians and other healthcare workers, and the facilitation of international research mentoring by a process of connecting new pneumonia investigators with established clinical investigators. SUMMARY: To improve clinical research in pneumonia, institutions need to have the appropriate infrastructure in place to support investigators in all aspects of the clinical research process. PMID- 29470253 TI - Management of nontuberculous mycobacterial pulmonary disease. AB - PURPOSE OF REVIEW: To highlight recent original research and specialty society guidelines regarding the diagnosis and treatment of nontuberculous mycobacterial (NTM) pulmonary disease. RECENT FINDINGS: The prevalence of NTM pulmonary disease has risen in recent years. The prevalence of individual NTM species varies geographically, although Mycobacterium avium complex (MAC) and Mycobacterium abscessus complex (MABC) remain among the most commonly encountered in many regions. Diagnosis and treatment of NTM pulmonary disease can be complex but guideline-based recommendations have been published. However, adherence to guideline recommendations is poor. Drug susceptibility testing plays a role with important caveats for treatment. Alternative therapies are being explored with older antimycobacterial drugs like clofazimine, which has demonstrated efficacy and tolerability for treatment-refractory NTM infections, and a novel formulation of amikacin for inhalation which may be better tolerated than parenteral administration. Several studies have shown that patients will have recurrences as high as 48%, and that these are not solely relapses but many cases are reinfections with a new organism. United States and European research registries of patients with non-cystic fibrosis bronchiectasis are expected to provide needed data on clinical characteristics of patients at risk for NTM pulmonary disease. SUMMARY: The evidence base for optimal management of NTM pulmonary disease is expanding but notable gaps in the literature remain. PMID- 29470255 TI - Clinical implications of oncogenic mutations in pulmonary Langerhans cell histiocytosis. AB - PURPOSE OF REVIEW: Langerhans cell histiocytosis (LCH) is a neoplasm of dendritic cells with a wide clinical spectrum. Localized pulmonary LCH occurs in young adults with a history of smoking and can either resolve spontaneously or lead to progressive decline in pulmonary function. Young children can also present with localized disease - frequently bone or skin - or with multifocal or multisystem disease. Clinical outcomes in these patients also vary widely, ranging from spontaneous resolution to multiorgan failure and death. This review describes recent developments in our understanding of the underlying pathogenesis of LCH and how these discoveries and other research are affecting how the disease is classified, treated and monitored. RECENT FINDINGS: Somatic mutations resulting in activation of the mitogen-activated protein kinase (MAPK) pathway were recently identified as a key pathogenetic mechanism in both pediatric and pulmonary LCH. SUMMARY: Knowledge of underlying pathogenetic mechanisms of LCH transforming how this disease and other histocytic/dendritic disorders are classified, treated and monitored. PMID- 29470256 TI - Systematic screening in hereditary hemorrhagic telangiectasia: a review. AB - PURPOSE OF REVIEW: Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant inherited disease characterized by telangiectasia and arteriovenous malformations (AVMs). To date, five genetic types of HHT and one combined juvenile polyposis syndrome and HHT are known. Clinical and genetic screening of patients suspected with HHT is recommended to confirm the diagnosis and to prevent complications associated with HHT. The aim of this article is to give an overview of the evidence and to formulate a recommendation for clinicians concerning screening for HHT. RECENT FINDINGS: Complications of HHT such as stroke, brain abscess and intracranial hemorrhage are caused by pulmonary and cerebral AVMs (CAVMs) and can often be prevented by screening and treatment when possible. Screening and treatment of these AVMs will result in an increased life expectancy comparable with that of the general population as opposed to unscreened and untreated HHT patients. SUMMARY: Screening of HHT patients and their first-degree relatives is recommended to prevent severe complications including stroke, brain abscess and intracranial hemorrhage. PMID- 29470257 TI - Dynamic Patient-Specific Three-Dimensional Simulation of Mitral Repair: Can We Practice Mitral Repair Preoperatively? AB - OBJECTIVE: Planned mitral repair strategies are generally established from preoperative echocardiography; however, specific details of the repair are often determined intraoperatively. We propose that three-dimensional printed, patient specific, dynamic mitral valve models may help surgeons plan and trial all the details of a specific patient's mitral repair preoperatively. METHODS: Using preoperative echocardiography, segmentation, modeling software, and three dimensional printing, we created dynamic, high-fidelity, patient-specific mitral valve models including the subvalvular apparatus. We assessed the accuracy of 10 patient mitral valve models anatomically and functionally in a heart phantom simulator, both objectively by blinded echocardiographic assessment, and subjectively by two mitral repair experts. After this, we attempted model mitral repair and compared the outcomes with postoperative echocardiography. RESULTS: Model measurements were accurate when compared with patients on anterior posterior diameter, circumference, and anterior leaflet length; however, less accurate on posterior leaflet length. On subjective assessment, Likert scores were high at 3.8 +/- 0.4 and 3.4 +/- 0.7, suggesting good fidelity of the dynamic model echocardiogram and functional model in the phantom to the preoperative three-dimensional echocardiogram, respectively. Mitral repair was successful in all 10 models with significant reduction in mitral insufficiency. In two models, mitral repair was performed twice, using two different surgical techniques to assess which provided a better outcome. When compared with the actual patient mitral repair outcome, the repaired models compared favorably. CONCLUSIONS: Complex mitral valve modeling seems to predict an individual patient's mitral anatomy well, before surgery. Further investigation is required to determine whether deliberate preoperative practice can improve mitral repair outcomes. PMID- 29470258 TI - Improving Quality of Dynamic Airway Computed Tomography Using an Expiratory Airflow Indicator Device. AB - PURPOSE: Dynamic computed tomography (CT) of the airways is increasingly used to evaluate patients with suspected expiratory central airway collapse, but current protocols are susceptible to inadequate exhalation caused by variable patient compliance with breathing instructions during the expiratory phase. We developed and tested a low-cost single-use expiratory airflow indicator device that was designed to improve study quality by providing a visual indicator to both patient and operator when adequate expiratory flow was attained. MATERIALS AND METHODS: A total of 56 patients undergoing dynamic airway CT were evaluated, 35 of whom were scanned before introduction of the indicator device (control group), with the rest comprising the intervention group. Lung volumes and tracheal cross-sectional areas on inspiratory/expiratory phases were computed using automated lung segmentation and quantitative software analysis. Inadequate exhalation was defined as absolute volume change of <500 mL during the expiratory phase. RESULTS: Fewer patients in the intervention group demonstrated inadequate exhalation. The average change in volume was higher in the intervention group (P=0.004), whereas the average minimum tracheal cross-sectional area was lower (P=0.01). CONCLUSIONS: The described expiratory airflow indicator device can be used to ensure adequate exhalation during the expiratory phase of dynamic airway CT. A higher frequency of adequate exhalation may improve reliability and sensitivity of dynamic airway CT for diagnosis of expiratory central airway collapse. PMID- 29470259 TI - Pure-Tone Audiometry With Forward Pressure Level Calibration Leads to Clinically Relevant Improvements in Test-Retest Reliability. AB - OBJECTIVES: Clinical pure-tone audiometry is conducted using stimuli delivered through supra-aural headphones or insert earphones. The stimuli are calibrated in an acoustic (average ear) coupler. Deviations in individual-ear acoustics from the coupler acoustics affect test validity, and variations in probe insertion and headphone placement affect both test validity and test-retest reliability. Using an insert earphone designed for otoacoustic emission testing, which contains a microphone and loudspeaker, an individualized in-the-ear calibration can be calculated from the ear-canal sound pressure measured at the microphone. However, the total sound pressure level (SPL) measured at the microphone may be affected by standing-wave nulls at higher frequencies, producing errors in stimulus level of up to 20 dB. An alternative is to calibrate using the forward pressure level (FPL) component, which is derived from the total SPL using a wideband acoustic immittance measurement, and represents the pressure wave incident on the eardrum. The objective of this study is to establish test-retest reliability for FPL calibration of pure-tone audiometry stimuli, compared with in-the-ear and coupler sound pressure calibrations. DESIGN: The authors compared standard audiometry using a modern clinical audiometer with TDH-39P supra-aural headphones calibrated in a coupler to a prototype audiometer with an ER10C earphone calibrated three ways: (1) in-the-ear using the total SPL at the microphone, (2) in-the-ear using the FPL at the microphone, and (3) in a coupler (all three are derived from the same measurement). The test procedure was similar to that commonly used in hearing-conservation programs, using pulsed-tone test frequencies at 0.5, 1, 2, 3, 4, 6, and 8 kHz, and an automated modified Hughson-Westlake audiometric procedure. Fifteen adult human participants with normal to mildly-impaired hearing were selected, and one ear from each was tested. Participants completed 10 audiograms on each system, with test-order randomly varied and with headphones and earphones refitted by the tester between tests. RESULTS: Fourteen of 15 ears had standing-wave nulls present between 4 and 8 kHz. The mean intrasubject SD at 6 and 8 kHz was lowest for the FPL calibration, and was comparable with the low frequency reliability across calibration methods. This decrease in variability translates to statistically-derived significant threshold shift criteria indicating that 15 dB shifts in hearing can be reliably detected at 6 and 8 kHz using FPL-calibrated ER10C earphones, compared with 20 to 25 dB shifts using standard TDH-39P headphones with a coupler calibration. CONCLUSIONS: These results indicate that reliability is better with insert earphones, especially with in-the-ear FPL calibration, compared with a standard clinical audiometer with supra-aural headphones. However, in-the-ear SPL calibration should not be used due to its sensitivity to standing waves. The improvement in reliability is clinically meaningful, potentially allowing hearing-conservation programs to more confidently determine significant threshold shifts at 6 kHz-a key frequency for the early detection of noise-induced hearing loss.

AB - Posterior reversible encephalopathy syndrome (PRES) is a newly defined syndrome; therefore, this transient clinical condition is not well known and probably underdiagnosed. It develops quickly with symptoms that are usually indistinguishable from eclampsia. Nurses need to be knowledgeable and aware of identifying symptoms and appropriate treatment. The condition is thought to share pathophysiology with eclampsia, and it is suggested that endothelial dysfunction combined with hypertension causes disruption in the blood brain barrier resulting in cerebral edema. Seizures develop secondary to cerebral edema, and mark later stages of the disease. Treatment is aimed at reducing blood pressure (BP) with antihypertensive therapy and seizure control with magnesium sulfate. When PRES is treated early, symptoms typically disappear within a few days and imaging studies normalize in several weeks. Permanent brain damage can occur if diagnosis and treatment are delayed. If PRES is suspected, thorough focused assessments and increased communication among the healthcare team are essential for patient care. When pregnant or postpartum women present with elevated BP accompanied with neurologic symptoms, imaging studies should be considered. An exemplar case is presented of a woman with normal prenatal course that is complicated by rapidly developing preeclampsia, eclampsia, and PRES. PMID- 29470267 TI - Pregnancy after Solid Organ Transplantation. AB - PURPOSE: To explore the reproductive decision-making process with women who were organ transplant recipients (renal, lung, & heart transplants). STUDY DESIGN AND METHODS: Grounded theory guided data collection and analyses. Mixed methods with audiotaped telephone interviews and a written survey measuring social support were used. As social support is critical for women who are organ transplant recipients considering pregnancy, a search for disconfirming evidence for social support via a survey and interviews was included. ANALYSES: Verbatim responses were analyzed through the constant comparative method using open, axial, and selective coding. Trustworthiness was established through prolonged engagement, member checking, and thick descriptions. RESULTS: Participants included 10 women who were solid organ recipients (2 lung, 1 heart, and 7 renal transplant recipients). The core theme was Wanting a child. Other themes included Getting information, Advocating, Dealing with problems, Preparing, Talking, Supporting, Coping, and Advising others. There was no evidence of a lack of social support as evaluated via the survey or interviews. CLINICAL IMPLICATIONS: This study provides new knowledge on clinical decision-making about pregnancy for women who are solid organ recipients and for healthcare professionals. Nurses can use these data to help guide women on how to obtain the most accurate information to make a personal decision about pregnancy and to develop support from their healthcare team and family. PMID- 29470269 TI - Tattoos and Piercings: Increasingly Accepted but Still Risky. PMID- 29470268 TI - Facilitating Early Breast Milk Expression in Mothers of Very Low Birth Weight Infants. AB - BACKGROUND: Although early initiation of human milk (HM) expression after birth is known to increase lactation success in mothers of very low birthweight (VLBW) infants, initiation is frequently delayed, potentially decreasing both short- and long-term HM production. Obstetrical (OB) nurses are typically the healthcare provider responsible for facilitating the initial HM expression session. As delays in initiation are common, it is likely that nurses experience obstacles to facilitation of an early initiation of HM expression. The purpose of this study was to determine barriers OB nurses perceive in facilitating early initiation of HM expression in mothers of VLBW infants. STUDY DESIGN AND METHODS: An online survey was administered to nurses from three tertiary care OB units in Florida to determine perceived barriers to early initiation of HM expression in mothers of VLBW infants. RESULTS: Eighty-three nurses completed the survey. The following barriers were identified: (1) lack of time and personnel to assist mothers with HM expression, (2) nurse's perception of the mother's acuity level, and (3) nurse's perception of maternal pain and stress. Discrepancies between nursing judgment, action, and knowledge of unit policies were evident. CLINICAL IMPLICATIONS: Obstetric nurses encounter barriers when facilitating early HM expression in mothers giving birth to VLBW infants. It is possible these barriers could be removed through improvements in education, use of innovative staffing strategies, and maintenance of evidence-based policies.

AB - STUDY DESIGN: Anatomic study in six formalin-fixed cadavers. OBJECTIVE: To determine the anatomical feasibility of transferring the S2 and S3 ventral roots (VRs) to S1 VR as a method for restoring bladder dysfunction in spinal cord injury. SUMMARY OF BACKGROUND DATA: A large quantity of researches of neuroanastomosis methods have been used for treating the bladder dysfunction in spinal cord injury. However, some limitations retard the development of those studies. METHODS: In this study, six formalin-fixed cadavers (four males, two females) were dissected. The feasibility of exposing the S1, S2, and S3 extradural nerve roots by the limited laminectomy, isolating the VR and dorsal roots from each extradural nerve root and transferring the S2,S3 VRs to the S1 VR were assessed. The pertinent distances and the nerve cross-sectional areas in each specimen were measured. The morphology of each nerve root was observed by hematoxylin-eosin staining. RESULTS: The limited laminectomy was performed to expose the S1 to S3 extradural nerve roots. The VRs could be isolated from each extradural nerve root at the location of the dorsal root ganglion and the hematoxylin-eosin staining showed that there were some connective tissues separating the VRs from the corresponding dorsal root ganglion. The S2 and S3 VRs have sufficient lengths to be transferred to S1 VR without grafting. The mean cross-sectional area of the S1 VR was 2.60 +/- 0.17 mm, and that was 1.02 +/- 0.32 mm and 0.51 +/- 0.21 mm of the S2 and S3 VRs, respectively. CONCLUSION: This study demonstrated that use of the S2 and S3 VRs for extradural transfer to S1 VR for restoring bladder dysfunction is surgically feasible. LEVEL OF EVIDENCE: 5. PMID- 29470277 TI - Does Duration of Pain at Baseline Influence Clinical Outcomes of Low Back Pain Patients Managed on an Evidence-based Pathway? AB - STUDY DESIGN: Longitudinal observational study. OBJECTIVE: To investigate the association between the duration of pain at baseline and the clinical outcomes of patients with low back pain (LBP) enrolled on the North East of England Regional Back Pain and Radicular Pain Pathway (NERBPP). SUMMARY OF BACKGROUND DATA: The NERBPP is a clinical pathway based upon National Institute for Health and Care Excellence (NICE) guidelines (2009) for LBP of <1-year duration. Recent changes to NICE guidelines (2016) advocate the same management for all LBP patients regardless of pain duration. METHODS: Patients with LBP referred onto the NERBPP by their General Practitioner between May 2015 and January 2017 were included. Data from 667 patients, who provided pre- and post data for pain (Numerical rating scale), function (Oswestry Disability Index), quality-of-life (EuroQol five-dimension, five-level questionnaire), anxiety (the Generalized Anxiety Disorder Screener), and depression (the Patient Health Questionnaire), were analyzed using a series of covariate-adjusted models. Patients were categorized into four groups based upon baseline pain duration: <3 months, >=3 to <6 months, >=6 months to <12 months, >=12 months. RESULTS: Each group showed improved outcomes greater than the minimal clinically important difference (MCID) for each measure as defined in NICE guidelines (2016). There was a trend toward better outcomes for those with shorter pain durations. The magnitude of the differences between the groups, in most instances, was below the MCID. For example, mean improvement in function for those with baseline pain duration <3 months was 20 points and 12 points for those of pain duration >=12 months, both above the MCID of >=10. CONCLUSION: Patients with different durations of LBP at baseline improved on the NERBPP, supporting the recent modification to NICE guidelines. However, those with shorter durations of pain may have superior outcomes in the short term, suggesting added benefit in getting patients onto the pathway in the early stages of LBP.

AB - STUDY DESIGN: A cadaveric biomechanical study designed to test the pullout strength of pedicle screws. OBJECTIVE: To evaluate the pullout strength of redirected pedicle screws with a larger diameter following lateral wall breach, redirected pedicle screws of the same diameter following medial wall breach, and redirected pedicle screws with a larger diameter following medial wall breach. SUMMARY OF BACKGROUND DATA: Screw malposition is one of the main pitfalls of inserting pedicle screws. Intraoperatively a malpositioned screw is redirected and inserted along the correct axis. METHODS: Forty-seven vertebrae (T9-L5) were harvested from eight fresh cadaveric spines. The 18 pedicle screws that breached the lateral wall were then removed and redirected using a pedicle screw of 1 mm larger in diameter. The 16 pedicle screws that had breached the medial wall were then removed and redirected using a pedicle screw of the same diameter. The other 13 pedicle screws that had breached the medial wall were then removed and redirected using a pedicle screw of 1 mm larger in diameter. The pullout strength was measured. RESULTS: Following lateral wall breach, mean pullout strength for the larger redirected screws was 46.9% greater than that of the correctly aligned screws. Following medial wall breach, mean pullout strength for the redirected screws of the same diameter was 20.6% less than that of the correctly aligned screws. Mean pullout strength for the larger pedicle screws following medial wall breach was 27.3% more than that of the correctly aligned screws. CONCLUSION: Redirected pedicle screws of larger diameter after a lateral or medial pedicle breach show recovery of pullout strength. However, the pullout strength of redirected pedicle screws of the same diameter after a medial pedicle breach is significantly less than that of correctly aligned screws. LEVEL OF EVIDENCE: 1. PMID- 29470279 TI - Acute Serum Cartilage Biomarker Response after Walking and Drop Landing. AB - INTRODUCTION: An in-depth understanding of the healthy cartilage response to activities of daily living is needed to better understand the complex relationship between cartilage health and loading. The purpose was to assess the role of loading on the acute serum cartilage oligomeric matrix protein (COMP) response in recreationally active individuals. METHODS: Forty individuals without previous lower extremity injury participated in this repeated-measures study in which each participant completed all conditions during independent data collection sessions separated by at least 1 wk. An antecubital blood draw was performed before and after walking, drop-landing, and control (i.e., sitting) conditions. Commercially available enzyme-linked immunosorbent assays measured COMP concentration. The acute COMP response was quantified as the percent change of COMP concentration from before to after each condition. A one-way, repeated measures ANOVA compared the acute COMP response between conditions. Post hoc Pearson product-moment correlation and chi-square analysis determined the relationship between the walking and drop-landing acute COMP response within individuals. RESULTS: Acute COMP response was greater after walking (+4.2, P = 0.008) and drop landing (+4.6%, P = 0.002) compared with control (-2.3%), but did not differ between the walking and drop-landing conditions (P = 0.596). The magnitudes of the acute COMP response during walking and drop landing were correlated (r = 0.56, P < 0.001). However, the direction (i.e., either increase or decrease) of COMP was not the same after the walking and drop-landing conditions (chi1 = 0.870, P = 0.351). CONCLUSIONS: Walking and drop landing produced a greater acute COMP response when compared with a control condition in healthy individuals, but the acute COMP response was similar between the two physical activity conditions, although the conditions differed in magnitude and frequency of loading. PMID- 29470280 TI - Blood Pressure Response during Cardiopulmonary Exercise Testing in Heart Failure. AB - INTRODUCTION: The prognostic value of peak VO2 and VE/VCO2 slope measured during cardiopulmonary exercise (CPX) testing has been well established in patients with advanced heart failure, but blood pressure response to exercise is less well characterized. METHODS: We retrospectively studied 151 outpatients who underwent CPX testing as part of an advanced heart failure evaluation. The outcome of interest was failure of medical management, defined by death, cardiac transplantation, or left ventricular assist device placement. Patients were stratified into tertiles by change in systolic blood pressure (SBP) (<13, 13-26, and >=27 mm Hg) during exercise. RESULTS: Patients in the lowest tertile had the lowest peak VO2 (10.2 vs 10.6 vs 13.6 mL.kg.min, P = <0.001), the highest VE/VCO2 slope (42.8 vs 42.1 vs 36.3, P = 0.030), the shortest mean exercise time (5.1 vs 6.0 vs 7.0 min, P = <0.001), and the highest probability of failure of medical management at 1.5 yr (0.69 vs 0.41 vs 0.34, P = 0.011). After multivariate adjustment, increased SBP <20 mm Hg during exercise was associated with a lower hazard of medical management failure (hazard ratio = 0.96, 95% confidence interval [CI] = 0.934-0.987), whereas SBP increases >20 mm Hg were associated with an increased hazard (hazard ratio = 1.046, 95% CI = 1.018-1.075). CONCLUSION: In conclusion, changes in SBP during CPX testing provide additional prognostic information above standard clinical variables. The peculiar increase in risk noted in those with a rise in SBP >20 mm Hg is less clear and needs to be investigated further. PMID- 29470281 TI - Vascular Nitric Oxide-Superoxide Balance and Thrombus Formation after Acute Exercise. AB - INTRODUCTION: An acute bout of strenuous exercise in humans results in transient impairment of nitric oxide (NO)-dependent function, but it remains unknown whether this phenomenon is associated with increased risk of thrombotic events after exercise. This study aimed to evaluate effects of a single bout of exhaustive running in mice on the balance of vascular NO/reactive oxygen species production, and on thrombogenicity. METHODS: At different time points (0, 2, and 4 h) after exercise and in sedentary C57BL/6 mice, the production of NO and superoxide (O2) in aorta was measured by electron paramagnetic resonance spin trapping and by dihydroethidium/high-performance liquid chromatography-based method, respectively, whereas collagen-induced thrombus formation was analyzed in a microchip-based flow-chamber system (total thrombus-formation analysis system). We also measured pre- and postexercise plasma concentration of nitrite/nitrate and 6-keto-PGF1alpha. RESULTS: An acute bout of exhaustive running in mice resulted in decreased production of NO and increased production of O2 in aorta, with maximum changes 2 h after completion of exercise when compared with sedentary mice. However, platelet thrombus formation was not changed by exercise as evidenced by unaltered time to start of thrombus formation, capillary occlusion time, and total thrombogenicity (area under the flow pressure curve) as measured in a flow-chamber system. Strenuous exercise increased the plasma concentration of nitrite but did not affect nitrate and 6-keto-PGF1alpha concentrations. CONCLUSION: An acute bout of strenuous exercise in mice reduced NO and in parallel increased O2 production in aorta. This response was most pronounced 2 h after exercise. Surprisingly, the reduced NO and increased O2 production in mice after exercise did not result in increased platelet-dependent thrombogenicity. These results show that transient reduction in NO bioavailability does not modify thromboresistance in healthy mice after exercise. PMID- 29470282 TI - The 2017 Shwachman Award. PMID- 29470283 TI - 2017 AAP Murray Davidson Award. PMID- 29470284 TI - Evolving Practice and Changing Phenotype in Pediatric Autoimmune Liver Disease: Outcomes From an Australian Center. AB - OBJECTIVES: Autoimmune liver disease (AILD) incorporates primary sclerosing cholangitis (PSC), autoimmune hepatitis (AIH), and autoimmune sclerosing cholangitis (ASC). ASC is a condition that includes overlap of AIH and PSC. We investigate changes in practice in relation to diagnosis and phenotype over 2 time periods. METHODS: Retrospective chart review was conducted from January 2000 to 2016. Data were divided into two 8-year cohorts, CI and C2. RESULTS: Data were collected in 75 children, 29 in 2000-2007 (C1) and 46 in 2008-2016 (C2). Presenting AILD type was AIH in 59%, ASC in 10%, and PSC in 31%. Final AILD type was AIH in 53%, ASC in 16%, and PSC in 31%. When comparing C1 to C2, those with AIH decreased (65% vs 45%) and those with ASC increased (14% vs 18%). Use of magnetic resonance cholangio-pancreatography increased from 34% in C1 to 65% in C2. Advanced liver disease on biopsy was noted in 53% of all children at presentation. Only 5 female children progressed to liver transplant (3 ASC-IBD [inflammatory bowel disease]; 1 PSC-IBD; 1 AIH). Colonoscopy performance increased from 48% in C1 to 63% in C2 with diagnosis of AILD-IBD increasing from 31% to 52%. Right-sided disease was present in 46% and macroscopic rectal sparing in 36% of those with ulcerative colitis (UC). Colectomy was required in 3 children with large duct PSC-IBD. CONCLUSIONS: PSC and ASC are increasing in relevance along with IBD and reflect increasing performance of magnetic resonance cholangio-pancreatography and colonoscopy. Large duct PSC and ASC with IBD are risk factors for colectomy and along with female gender, for liver transplant. PMID- 29470285 TI - Clinical and Imaging Predictors of Surgical Splenorenal Shunt Dysfunction in Pediatric Patients. AB - PURPOSE: Few established criteria exist to prompt angiographic evaluation and intervention for surgically created splenorenal shunts (SRS). Clinical and Doppler ultrasound (DUS) imaging predictors of shunt dysfunction were evaluated in this retrospective study. MATERIALS AND METHODS: Consecutive patients undergoing SRS angiography over a 10-year period were retrospectively identified. Preangiography platelet count and DUS measurements of spleen diameter, maximum splenic vein velocity, and maximum shunt velocity were assessed and compared to findings at subsequent catheter angiography. RESULTS: Twenty-six SRS angiograms were performed in 16 patients. Two of the 26 procedures were excluded from analysis due to insufficient baseline preangiography clinical and DUS data. In the remaining 24 cases, significant stenosis/occlusion was confirmed at angiography in 20, whereas wide patency was seen in 4. For the 20 cases of angiographically confirmed significant stenosis/occlusion, when compared to baseline post-SRS creation to immediate preangiography evaluation there was a greater decrease in platelet count (-51.8% vs -19.4%), a greater increase in spleen diameter (+13.4% vs +3.7%), a greater increase in maximum shunt velocity (+74.7% vs +59.7%), and a greater decrease in splenic vein velocity (-25.0% vs 18.5%). CONCLUSION: Clinical evidence of splenic sequestration and DUS finding of increased maximum shunt velocity correlate with angiographic findings of SRS dysfunction and could be used to help predict the need for shunt intervention.

PMID- 29470286 TI - Genetic Variants Associated With Obesity and Insulin Resistance in Hispanic Boys With Nonalcoholic Fatty Liver Disease. AB - BACKGROUND AND OBJECTIVES: Nonalcoholic fatty liver disease (NAFLD) disproportionately affects Hispanic boys. Further, obesity and insulin resistance are major risk factors for NAFLD. No gene localization studies had been performed on children with biopsy-proven NAFLD. This study aims to identify genomic variants associated with increased adiposity and insulin resistance in a population of children with varying histologic severity of NAFLD. METHODS: We conducted a genome-wide association scan (GWAS) including 624,297 single nucleotide polymorphisms (SNPs) distributed among all 22 autosomal chromosomes in 234 Hispanic boys (up to 18 years of age) who were consecutively recruited in a prospective cohort study in the Nonalcoholic Steatohepatitis Clinical Research Network Studies. Traits were examined quantitatively using linear regression. SNPs with P value <10 and a minor allele frequency >5% were considered potentially significant. RESULTS: Evaluated subjects had a median age of 12.0 years, body mass index (BMI) of 31.4, and hemoglobin A1C (Hgb A1C) of 5.3. The prevalence of NAFL, borderline NASH, and definite NASH were 23%, 53%, and 22%, respectively. The GWAS identified 10 SNPs that were associated with BMI z score, 6 within chromosome 2, and 1 within CAMK1D, which has a potential role in liver gluconeogenesis. In addition, the GWAS identified 9 novel variants associated with insulin resistance: HOMA-IR (6) and HbA1c (3). CONCLUSIONS: This study of Hispanic boys with biopsy-proven NAFLD with increased risk for the metabolic syndrome revealed novel genetic variants that are associated with obesity and insulin resistance. PMID- 29470288 TI - Digested Early Preterm Human Milk Suppresses Tumor Necrosis Factor-induced Inflammation and Cytotoxicity in Intestinal Epithelial Cells. AB - OBJECTIVES: The aim of this study was to determine the effect of digested whole human milk (HM; first sample available after birth from mothers of premature infants) on inflammation, oxidative stress, and cytotoxicity in Caco-2 human intestinal epithelial cells stimulated with lipopolysaccharides or tumor necrosis factor (TNF) to mimic the potential in vivo insults facing the premature infant's gastrointestinal tract. METHODS: Fully differentiated Caco-2 cells were exposed to digested HM (n = 10; samples from 10 different individuals) before stimulation with lipopolysaccharides, TNF, or no stimulation overnight. Inflammation was determined by production of interleukin-8, oxidative stress by levels of F2 isoprostane, and cytotoxicity by released lactate dehydrogenase. RESULTS: HM significantly suppressed interleukin-8 production and cytotoxicity in TNF stimulated cells, while also suppressing cell death under baseline conditions. Individual HM samples differed widely in their ability to modulate cellular responses. CONCLUSIONS: Results from this study provide evidence that digested HM can reduce both an exaggerated inflammatory response and intestinal damage that contribute to the pathogenesis of necrotizing enterocolitis.

AB - OBJECTIVES: The aim of this study was to evaluate the effect of autoimmune hepatitis (AIH) on the quality of life of children and adolescents and to identify which variables effect health-related quality of life (HRQoL). METHODS: The Pediatric Quality of Life Inventory 4.0 (PedsQL 4.0) was used to evaluate HRQoL. In addition, a questionnaire was applied which included signs, symptoms, and use of medications. RESULTS: A total of 43 patients (mean age, 15.0 +/- 3.9 years; 65.1% girls; 90.7% with type 1 AIH) was evaluated. Advanced liver disease was present in 30.2%, and 18.6% had sclerosing cholangitis. Treatment was effective in 93.1% of patients. The lowest HRQoL scores were associated with the school (67.7), emotional (68.2), and psychosocial (75.5) domains. Compared with healthy children, patients presented lower scores on the total, psychosocial, emotional, and school domains (P < 0.05). The presence of symptoms (beta = 0.39, P < 0.01), extrahepatic autoimmune diseases (beta = 0.27, P < 0.05), and a dislike of taking medication (beta = 0.40, P < 0.01) negatively affected the psychosocial PedsQL 4.0 score, and the presence of symptoms (beta = 0.40, P < 0.01) negatively affected the total PedsQL 4.0 score. CONCLUSIONS: AIH has a significant and negative effect on HRQoL among children and adolescents. The presence of symptoms, extrahepatic autoimmune diseases, and a dislike of taking medication were associated with the worsening of HRQoL. Providers should work with professionals trained to improve QoL to help improve treatment adherence and disease outcomes. PMID- 29470291 TI - Recurrent Abdominal Pain in Children: Summary Evidence From 3 Systematic Reviews of Treatment Effectiveness. AB - OBJECTIVES: Between 4% and 25% of school-aged children complain of recurrent abdominal pain (RAP) severe enough to interfere with their daily activities. METHODS: We carried out a systematic review of randomised controlled trials (RCTs) in eleven databases and 2 trials registries from inception to June 2016. An update search was run in November 2017. All screening was performed by 2 independent reviewers. Included studies were appraised using the Cochrane risk of bias tool and the evidence assessed using GRADE. We included any dietary, pharmacological or psychosocial intervention for RAP, defined by Apley or an abdominal pain-related functional gastrointestinal disorder, as defined by the Rome III criteria, in children and adolescents. RESULTS: We included 55 RCTs, involving 3572 children with RAP (21 dietary, 15 pharmacological, 19 psychosocial, and 1 multiarm). We found probiotic diets, cognitive-behavioural therapy (CBT) and hypnotherapy were reported to reduce pain in the short-term and there is some evidence of medium term effectiveness. There was insufficient evidence of effectiveness for all other dietary interventions and psychosocial therapies. There was no robust evidence of effectiveness for pharmacological interventions. CONCLUSIONS: Overall the evidence base for treatment decisions is poor. These data suggest that probiotics, CBT, and hypnotherapy could be considered as part of holistic management of children with RAP. The evidence regarding relative effectiveness of different strains of probiotics is currently insufficient to guide clinical practice. The lack of evidence of effectiveness for any drug suggests that there is little justification for their use outside of well-conducted clinical trials. There is an urgent need for high-quality RCTs to provide evidence to guide management of this common condition. PMID- 29470292 TI - Rectal Picking Masquerading as Inflammatory Bowel Disease in Prader-Willi Syndrome. AB - Prader-Willi syndrome (PWS) is a genetic syndrome in which individuals have multisystem medical challenges. Gastroenterological difficulties in the syndrome include decreased vomiting, constipation, delayed gastric emptying, delayed colonic transit, dysphagia, increased choking, and increased risk of gastric dilation and rupture. In addition, self-injurious behavior such as rectal picking may be present and severe enough to lead to rectal ulceration and bleeding. Many patients have extensive gastroenterological workup and treatment before their ultimate diagnosis of severe rectal picking. We describe 4 new cases of rectal picking in individuals with PWS leading to rectal bleeding and ulceration as well as a review of the literature of prior cases of severe rectal picking in PWS and potential treatment options. It is important to recognize these cases early in order to prevent unnecessary treatments and implement appropriate behavioral interventions. PMID- 29470293 TI - Medium-term Outcome of Laparoscopic Kasai Portoenterostomy for Biliary Atresia With 49 Cases. AB - OBJECTIVE: The aim of this study was to evaluate the mid-term results of laparoscopic Kasai portoenterostomy (LKPE) for biliary atresia (BA) at our hospital. METHODS: From May 2009 to May 2012, the charts of infants with BA who underwent LKPE were reviewed retrospectively. The clearance of jaundice (CJ) as well as 3-year, and 5-year survival with native liver (SNL) rates were analyzed and compared with those after open Kasai portoenterostomy (OKPE). RESULTS: Forty nine patients with BA who underwent LKPE were assigned to group A, and 40 patients with BA who underwent OKPE were assigned to group B. All patients in both groups had type III non-syndromic BA, and the LKPE and OKPE procedures were performed by 2 different surgical teams at our hospital. After median follow-up periods of 77 months in group A and 79 months in group B, the CJ and 3- and 5 year SNL rates were 61.2%, 55.1%, and 36.7% in group A, and 45.0%, 37.5%, and 25.0% in group B, respectively. The difference of CJ between group A and group B was not significant. The Kaplan-Meier method analysis showed that the difference in SNL between group A and group B was not significant either. CONCLUSIONS: LKPE for patients with BA was a technically feasible and alternative procedure to OKPE. The 3- and 5-year SNL rates after LKPE were not different compared to those after OKPE.

AB - In this prospective cohort study, we examine the feasibility of a protocol to optimize microbiota for fecal microbiota transplantation (FMT). Donor stool metrics generally accepted as markers of gut health were used to select a stool donor based on superior microbial diversity, balanced constitution of Bacteroidetes versus Firmicutes and high concentration of fecal butyrate. Selected donor microbiota was then administered via FMT. A total of 10 patients with median age of 12 years with recurrent Clostridium difficile infection received the intervention. The rate of recurrence-free resolution with 1-2 FMTs was 100% at Week 10. With a single FMT, 80% of patients cleared Clostridium difficile infection without recurrence, whereas 20% of patients required a single re-treatment. No serious adverse events occurred. Microbiota sequencing revealed that recipients' gut microbiota phylogenic diversity increased by 72-hours post transplantation, with sustainment over 10-week follow-up. This study highlights the feasibility of purposefully selecting the most ideal microbiota for transplantation. PMID- 29470298 TI - CHOROIDAL NEOVASCULARIZATION ASSOCIATED WITH RETINAL PIGMENT EPITHELIAL TEAR IMAGED BY OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY. AB - PURPOSE: To report a patient presenting a retinal pigment epithelial tear in which optical coherence tomography angiography enabled the visualization of subfoveal choroidal neovascularization (CNV) not evidenced by the fluorescein angiography. She was treated with 3 monthly intravitreous anti-VEGF injections and intraretinal fluid resolution occurred. METHODS: Observational case report. RESULTS: A 62-year-old Caucasian woman presented with decreased visual acuity in the right eye for 3 months. Fundus biomicroscopy revealed a yellowish macular lesion associated with intraretinal hemorrhage. Fluorescein angiography showed a large hyperfluorescent area consistent with window defect. Optical coherence tomography showed a retinal pigment epithelial tear with subretinal fluid. However, there was no clear evidence of CNV on fluorescein angiography or OCT. Optical coherence tomography angiography confirmed the presence of an active CNV by the visualization of the neovascular network in the region corresponding to the scrolled up retinal pigment epithelium. CONCLUSION: This case report demonstrates that optical coherence tomography angiography can be useful to confirm the presence of CNV in cases where fluorescein angiography and OCT cannot establish the diagnosis. The reported case suggests the applicability of optical coherence tomography angiography in patients in whom retinal pigment epithelial tear is detected and associated CNV is suspected. PMID- 29470299 TI - CHOROIDAL THICKNESS CHANGES IN A PATIENT DIAGNOSED WITH CENTRAL SEROUS CHORIORETINOPATHY DURING FOLLOW-UP FOR PACHYCHOROID PIGMENT EPITHELIOPATHY. AB - PURPOSE: To evaluate chronological changes in choroidal thickness in a patient with pachychoroid pigment epitheliopathy (PPE) who was later diagnosed with central serous chorioretinopathy (CSC) during follow-up. METHODS: Case report. RESULTS: A 43-year-old man complained of metamorphopsia in the left eye. Funduscopy showed several punctate white subretinal lesions at the macula, but no macular serous retinal detachment in the left eye. Retinal pigment epithelium abnormality without serous retinal detachment at the macula on optical coherence tomography and choroidal vascular hyperpermeability on indocyanine green angiography suggested PPE in the left eye. Macular lesions disappeared with no treatment. Twenty-five months after the initial visit, PPE recurred in the left eye. Thirty-five months after the initial visit, the patient was diagnosed with CSC in the left eye. Macular serous retinal detachment spontaneously resolved. In the eye with PPE and CSC, the choroid was consistently thicker than that in the fellow eye during follow-up. The choroid became thicker during the alternate onsets of PPE and CSC and thinner after regression of these diseases. CONCLUSION: These results suggest that PPE and CSC overlap clinically and choroidal thickening is involved in the pathogenesis of both diseases. PMID- 29470300 TI - RETINOCYTOMA WITH VITREOUS SEEDING: NEW INSIGHTS FROM ENHANCED DEPTH IMAGING OPTICAL COHERENCE TOMOGRAPHY AND HIGH-RESOLUTION POSTERIOR SEGMENT ULTRASONOGRAPHY. AB - PURPOSE: To report an atypical case of a patient with symptomatic retinocytoma associated with diffuse calcified vitreous seeds. METHODS: Retrospective chart review. RESULTS: A 46-year-old healthy woman presented with a history of floaters in the right eye for several months. She had been referred for abnormal findings in the retina and vitreous on routine examination. Visual acuity was 20/20. An incidental retinocytoma associated with extensive calcified vitreous seeding was observed. Enhanced depth optical coherence tomography showed an absence of normal retinal layers with numerous cystoid cavities throughout the lesion. High resolution 20-MHz posterior B-scan ultrasonography demonstrated that the calcified vitreous seeds emanated from the peaked portion of the retinal tumor. CONCLUSION: Calcified vitreous seeding is a rare finding associated with retinocytomas. Enhanced depth imaging optical coherence tomography and high resolution B-scan ultrasonography may be useful tools in the diagnosis of this uncommon retinal tumor. PMID- 29470301 TI - A CASE OF INTRARETINAL PERIPAPILLARY NEOVASCULARIZATION IN ABCA4-RELATED RETINOPATHY. AB - PURPOSE: To report a case of ABCA4-related retinopathy and potential complications. METHODS: The authors describe a case report of intraretinal neovascularization in a patient with ABCA4-related retinopathy and describe the multimodal retinal imaging findings. RESULTS: A 49-year-old woman presents with cystoid macular edema and diffuse intraretinal and perivascular hyperpigmentation in both eyes. Genetic testing confirmed ABCA4-related retinopathy. Fluorescein angiography revealed peripapillary intraretinal neovascularization in the absence of any other identifiable retinal pathology. CONCLUSION: To the authors' knowledge, this is the first reported case of intraretinal neovascularization associated ABCA4-related retinopathy. Ancillary testing of ABCA4-related retinopathy with fluorescein angiography or optical coherence tomography angiography may be helpful in identifying this rare complication. PMID- 29470302 TI - HYDRATION FOLDS IN RHEGMATOGENOUS RETINAL DETACHMENT. AB - PURPOSE: To describe two cases of retinal detachment with hydration folds and discuss the possible cause of these outer retinal abnormalities. METHODS: The medical and imaging records of two patients with retinal detachment and hydration folds were examined. PATIENTS: A 43-year-old myopic woman who developed a retinal detachment secondary to a macular hole and a 35-year-old man referred with a rhegmatogenous retinal detachment masquerading as an exudative detachment were each found to have retinal hydration folds. RESULTS: On near-infrared reflectance imaging, the hydration folds appeared similar to eddy currents, and these corresponded to curvilinear outer retinal plications on optical coherence tomography. The photoreceptor outer segments appeared thickened and elongated, and there was apparent lateral expansion of the outer retinal layers. CONCLUSION: Hydration folds are found in rhegmatogenous retinal detachment and demonstrate reproducible imaging characteristics on near-infrared imaging and optical coherence tomography. The cause for such outer retinal plications is currently unknown. We suspect that they form as a result of hydration of the glycosaminoglycans in the interphotoreceptor matrix, which lies between the photoreceptors. Additional studies are warranted to explore this pathophysiology. PMID- 29470303 TI - Clues in Histopathological Diagnosis of Panniculitis. AB - BACKGROUND: Panniculitides comprise a group of heterogeneous inflammatory diseases. Nevertheless, histopathological study along with clinicopathological correlation usually led to a specific diagnosis. In most textbooks, the first step in the diagnosis is to classify them as mostly septal or lobular depending on where the inflammatory infiltrate is located. The second step is deciding if vasculitis is present or not. Finally, the third step is further characterizing the inflammatory infiltrate. However, in addition to the algorithmic approach to panniculitis diagnosis, some subtle changes may help to the diagnosis. OBJECTIVE: To review some clues in panniculitis dermatopathological diagnosis such as presence of granulation tissue, sclerotic connective tissue septa, small granulomas arranged around a central clear space, so-called ghost adipocytes, needle-shaped crystals, small lobules with a proliferation of capillaries, Splendore-Hoeppli phenomenon, refractile microspheres, neutrophilic infiltrates, granulomas and fibroplasia or presence of adipose tissue in dermis. METHODS: We have compiled 12 clues based in our personal experience in this field. LIMITATIONS: Specificity and sensibility of every clue may vary and these clues are a guide to correct diagnoses that should rely in clinicopathological correlation. CONCLUSION: Knowledge of these 12 clues will help to increase the diagnostic accuracy in panniculitis diagnosis. PMID- 29470304 TI - Index Case of Cutaneous Follicular Mycosis Fungoides With Central Nervous System Involvement and Review of Literature. AB - Central nervous system involvement by mycosis fungoides (MF) is rare and is usually seen in advanced stages of the disease. We describe a patient with early stage follicular MF who presented with changes in mental status. Despite an initial diagnosis of vasculitis based on clinical and brain biopsy results, the postmortem examination revealed extensive infiltration of MF cells throughout the brain with leptomeningeal involvement. This case in addition to the accompanied review of literature illustrates the importance of the awareness of central nervous system involvement by MF and highlights the need for an urgent neurologic evaluation in patients with a history of MF now presenting with neurologic signs or symptoms.

PMID- 29470308 TI - EFFICACY AND SAFETY OUTCOMES OF INTRAVITREAL AFLIBERCEPT FOCUSING ON PATIENTS WITH DIABETIC MACULAR EDEMA FROM JAPAN. AB - PURPOSE: To evaluate the efficacy and safety of intravitreal aflibercept injection (IAI) in Japanese patients with diabetic macular edema (DME). METHODS: VIVID-DME was a Phase 3 study comprising patients with DME randomized 1:1:1 to IAI 2 mg every 4 weeks (2q4), IAI 2 mg every 4 weeks until Week 16 then 8-week dosing (2q8), and laser. A total of 403 patients (76 Japanese) were included in this study. VIVID-Japan (72; all Japanese patients) was a nonrandomized, open label study comprising Japanese patients with DME receiving IAI 2q4 until Week 16, then 2q8. Primary efficacy endpoint (Week 52) of VIVID-DME was mean change from baseline in best-corrected visual acuity; VIVID-Japan evaluated safety and tolerability. RESULTS: Mean change in best-corrected visual acuity (letters) for 2q4, 2q8, and laser groups was +10.6, +10.9, and +1.2 and +9.8, +9.5, and +1.1 in the non-Japanese and Japanese populations of VIVID-DME, respectively. In VIVID Japan, it was +9.3 for IAI 2q8. Intravitreal aflibercept injection also provided consistently greater benefits for anatomical outcomes versus laser. Adverse events were consistent with the known safety profile of IAI. CONCLUSION: In Japanese patients with DME, IAI treatment was superior to laser for visual and anatomical outcomes and resulted in efficacy and safety outcomes similar to those in a non-Japanese patient population.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

PMID- 29470311 TI - ROUTINE FUNDUS SCREENING OF FAMILIES OF CHILDREN WITH RETINOBLASTOMA: A Prospective Study of 131 Consecutive Families. AB - PURPOSE: To discuss the importance of routine ophthalmic examination of parents and siblings of retinoblastoma (RB) patients. METHODS: Prospective nonrandomized observational/interventional case series of consecutive families of 131 RB patients. RESULTS: Routine ophthalmic examination of families (parents and siblings) of 131 consecutive newly diagnosed RB patients, including 262 parents and 23 siblings, revealed spontaneously regressed RB in at least 1 parent of 10 (8%) patients and active RB in at least 1 sibling of 3 (2%) patients. Of the 10 parents with spontaneously regressed RB, the lesions were unilateral (n = 7) or bilateral (n = 3). The regression patterns (n = 13) were comparable with postirradiation regression patterns Type 1 (n = 3), Type 2 (n = 2), Type 3 (n = 2), and Type 4 (n = 3), and spontaneous phthisis bulbi (n = 3). Fundus screening of siblings revealed active RB in at least 1 sibling of 3 (2%) patients. Of these 3 siblings, 2 had unilateral and 1 had bilateral disease. The mean age at detection of RB was 15 months (median, 6 months; range, 2-36 months). The disease was unilateral in 2 and bilateral in 1 patient. Based on International Classification of Intraocular Retinoblastoma, the tumors (n = 4) were classified as Group A (n = 2) and Group B (n = 2). CONCLUSION: Routine fundus screening of siblings allows for early detection of RB in otherwise asymptomatic children. Detection of spontaneously regressed RB in parents may act as a surrogate marker for germline RB1 mutation and is helpful in genetic counseling. PMID- 29470312 TI - Heterozygous mutations in GTP-cyclohydrolase-1 reduce BH4 biosynthesis but not pain sensitivity. AB - Human studies have demonstrated a correlation between noncoding polymorphisms of "the pain protective" haplotype in the GCH1 gene that encodes for GTP cyclohydrolase I (GTPCH1)-which leads to reduced tetrahydrobiopterin (BH4) production in cell systems-and a diminished perception of experimental and clinical pain. Here, we investigate whether heterozygous mutations in the GCH1 gene which lead to a profound BH4 reduction in patients with dopa-responsive dystonia (DRD) have any effect on pain sensitivity. The study includes an investigation of GCH1-associated biomarkers and pain sensitivity in a cohort of 22 patients with DRD and 36 controls. The patients with DRD had, when compared with controls, significantly reduced levels of BH4, neopterin, biopterin, and GTPCH1 in their urine, blood, or cytokine-stimulated fibroblasts, but their pain response with respect to non-painful stimulation, (acute) stimulus-evoked pain, or pain response after capsaicin-induced sensitization was not significantly different. A family-specific cohort of 11 patients with DRD and 11 controls were included in this study. The patients with DRD were heterozygous for the pain protective haplotype in cis with the GCH1 disease-causing mutation, c.899T>C. No effect on pain perception was observed for this combined haplotype. In conclusion, a reduced concentration of BH4 is not sufficient to alter ongoing pain sensitivity or evoked pain responses. PMID- 29470313 TI - Injustice perceptions about pain: parent-child discordance is associated with worse functional outcomes. AB - Pain is experienced within and influenced by social environments. For children with chronic pain, the child-parent relationship and parental beliefs about pain are particularly important and may influence pain outcomes. Pain-related injustice perceptions have recently been identified as an important cognitive emotional factor for children with pain. The current study aimed to better understand the pain-related injustice perceptions of children with chronic pain and their parents. The sample consisted of 253 pediatric chronic pain patients (mean age = 14.1 years, 74% female) presenting to a tertiary pain clinic. Patients completed measures of pain intensity, pain-related injustice perceptions, stress, functional disability, and quality of life. Parents completed a measure of pain-related injustice perceptions about their child's pain. Child-parent dyads were categorized into 1 of 4 categories based on the degree of concordance or discordance between their scores on the injustice measures. One-way analysis of variances examined differences in pain intensity, stress, functional disability, and quality of life across the 4 dyad categories. Our findings indicated that both the degree (concordant vs discordant) and direction (discordant low child-high parent vs discordant high child-low parent) of similarity between child and parent injustice perceptions were associated with child-reported pain intensity, stress, functional disability, and quality of life. The poorest outcomes were reported when children considered their pain as highly unjust, but their parents did not. These findings highlight the important role of parents in the context of pain-related injustice perceptions in pediatric chronic pain. PMID- 29470315 TI - A Global Presence. PMID- 29470314 TI - Genetic variation in P2RX7 and pain tolerance. AB - P2X7 is a nonselective cation channel activated by extracellular ATP. P2X7 activation contributes to the proinflammatory response to injury or bacterial invasion and mediates apoptosis. Recently, P2X7 function has been linked to chronic inflammatory and neuropathic pain. P2X7 may contribute to pain modulation both by effects on peripheral tissue injury underlying clinical pain states, and through alterations in central nervous system processing, as suggested by animal models. To further test its role in pain sensitivity, we examined whether variation within the P2RX7 gene, which encodes the P2X7 receptor, was associated with experimentally induced pain in human patients. Experimental pain was assessed in Tromso 6, a longitudinal and cross-sectional population-based study (N = 3016), and the BrePainGen cohort, consisting of patients who underwent breast cancer surgery (N = 831). For both cohorts, experimental pain intensity and tolerance were assessed with the cold-pressor test. In addition, multisite chronic pain was assessed in Tromso 6 and pain intensity 1 week after surgery was assessed in BrePainGen. We tested whether the single-nucleotide polymorphism rs7958311, previously implicated in clinical pain, was associated with experimental and clinical pain phenotypes. In addition, we examined effects of single-nucleotide polymorphisms rs208294 and rs208296, for which previous results have been equivocal. Rs7958311 was associated with experimental pain intensity in the meta-analysis of both cohorts. Significant associations were also found for multisite pain and postoperative pain. Our results strengthen the existing evidence and suggest that P2X7 and genetic variation in the P2RX7-gene may be involved in the modulation of human pain sensitivity. PMID- 29470316 TI - Protecting the Brain With Xenon Anesthesia for Neurosurgical Procedures. AB - Xenon possesses some, but not all, of the clinical features of an ideal anesthetic agent. Besides well-known advantages of rapid awakening, stable hemodynamics and lack of biotransformation, preclinical data lead to the expectation of xenon's advantageous use for settings of acute ongoing brain injury; a single randomized clinical trial using an imaging biomarker for assessing brain injury corroborated xenon's preclinical efficacy in protecting the brain from further injury. In this review, we discuss the mechanisms and hence the putative applications of xenon for brain protection in neurosurgery. Although the expense of this rare monoatomic gas will likely prevent its widespread penetration into routine clinical neurosurgical practice, we draw attention to the theoretical benefits of xenon anesthesia over other anesthetic regimens for awake craniotomy and for neurosurgery in older, high-risk, and sicker patients. PMID- 29470317 TI - The Effects of Leukocyte Filtration on Cell Salvaged Autologous Blood Transfusion on Lung Function and Lung Inflammatory and Oxidative Stress Reactions in Elderly Patients Undergoing Lumbar Spinal Surgery. AB - BACKGROUND: This study was designed to investigate the effects of leukocyte filtration of autologous salvaged blood on lung function, lung inflammatory reaction, and oxidative stress reaction in elderly patients undergoing lumbar spinal surgery. MATERIALS AND METHODS: Sixty elderly patients undergoing lumbar spinal surgery were randomly divided into 2 groups: Leukocyte Filter group and Control group. Serum levels of inflammatory markers including white blood cell and polymorphonuclear count, neutrophil elastase, serum surfactant protein A, methane dicarboxylic aldehyde, superoxide dismutase, interleukin (IL)-6, IL-8, tumor necrosis factor-alpha, and respiratory function markers including dynamic respiratory system compliance, oxygenation index, and respiratory index were measured immediately before induction of anesthesia (T0), immediately before blood transfusion (T1), and 1 (T2), 6 (T3), and 12 hours (T4) after end of blood transfusion. RESULTS: The Leukocyte Filter group had higher dynamic respiratory system compliance at T2, oxygenation index at T2 and T3, respiratory index and superoxide dismutase at T2, T3, and T4 than those in the Control group (P<0.05). The Leukocyte Filter group had lower white blood cell, polymorphonuclear count, neutrophil elastase, serum surfactant protein A, methane dicarboxylic aldehyde, IL-6, IL-8, and tumor necrosis factor-alpha at T2, T3, and T4 than those in the Control group (P<0.05). There were no significant differences in adverse reactions related specifically to blood transfusion or postoperative respiratory complications within 72 hours. CONCLUSIONS: Salvaged autologous blood leukocyte filtration can improve ventilation, promote gas exchange and oxygenation, and inhibit lung inflammatory and oxidative stress reactions in elderly patients undergoing lumbar spinal surgery. PMID- 29470319 TI - Splenic Rupture in Children With Portal Hypertension. AB - INTRODUCTION: Massive splenomegaly from portal hypertension (PHTN) in children raises the specter of splenic rupture; however, the incidence, etiology, and risk of rupture have not been studied, nor have existing practices to reduce risk. We therefore performed an international survey to describe the splenic rupture cases in PHTN and to describe the existing empirical practice among hepatologists. METHODS: A questionnaire was constructed to elicit cases of splenic rupture and collect hepatologists' common practices for prevention of splenic rupture. Pediatric hepatologists working in selected tertiary academic centers in the United States, Canada, and the United Kingdom were contacted. RESULTS: Hepatologists from 30 of 35 centers who met the inclusion criteria replied to the survey. Thirteen cases of splenic rupture were described of which 11 resulted from trauma. In the opinion of the practitioners, high-risk activities were football, hockey, and wrestling. Sixty-one percent recommended total restriction from high-risk activities. Seventy-four percent stated that platelet count had no effect on this decision and 61% advised a spleen guard for certain activities. CONCLUSIONS: Splenic rupture in patients with PHTN and splenomegaly seems to be rare. The reported splenic rupture cases were mostly related to falling (and not to participation in sports). There was general agreement among hepatologists about restricting high impact sports. There was variation in recommendations regarding the use of a spleen guard. The authors recommend use of spleen guards in children with splenomegaly from PHTN for physical activities with risk of fall or blunt abdominal trauma. PMID- 29470320 TI - Exchangeable Zinc Pool Size at Birth in Pakistani Small for Gestational Age and Appropriate for Gestational Age Infants Do Not Differ But Are Lower Than in US Infants. AB - OBJECTIVES: Small for gestational age (SGA) infants are more susceptible to infectious morbidity and growth faltering compared to their appropriate for gestational age (AGA) counterparts. Zinc supplementation of SGA infants may be beneficial but the underlying susceptibility to zinc deficiency of SGA infants has not been examined. METHODS: In a community-based, observational, longitudinal study in a peri-urban settlement of Karachi, Pakistan, we compared the size of the exchangeable zinc pools (EZPs) in term SGA and AGA infants at birth and at 6 months of age, hypothesizing that the EZP would be lower in the SGA group. To measure EZP size, a zinc stable isotope was intravenously administered within 48 hours of birth (n = 17 and 22) at 6 months (n = 11 and 14) in SGA and AGA infants, respectively. Isotopic enrichment in urine was used to determine EZP. RESULTS: No significant difference was detected in the mean (+/-standard deviation) EZP between SGA and AGA infants at birth, with values of 9.8 +/- 3.5 and 10.1 +/- 4.1 mg/kg, respectively (P = 0.86), or at 6 months. Longitudinal EZP measurements demonstrated a significant decline in EZP relative to body weight in both groups at 6 months (P < 0.001). Mean EZP (adjusted for body weight) size at birth for the combined Pakistani groups was significantly lower than AGA infants at birth in the United States (P = 0.017). CONCLUSIONS: These results did not support a difference in zinc endowment between SGA and AGA Pakistani infants. They, however, do suggest lower in utero zinc transfer to the fetus in a setting where poor maternal nutritional status may confer a high susceptibility to postnatal zinc deficiency. PMID- 29470321 TI - Long-term Exposure of Children to a Mixed Lipid Emulsion Is Less Hepatotoxic Than Soybean-based Lipid Emulsion. AB - Lipid emulsions have been associated with liver injury. Newer mixed emulsions (ML), such as SMOFlipid (Fresenius Kabi, Germany), are thought to be more hepatoprotective than soybean-based emulsions (SL), such as Intralipid (Baxter). Pediatric studies comparing long-term use between the 2 are limited. This study compares the severity of hepatic injury between a prospective cohort of hospitalized children on ML (n = 20) and a historical age- and diagnosis-matched cohort of hospitalized children on SL (n = 20). Median exposure to ML and SL were 10 versus 6 weeks (P = 0.030), respectively, at similar median lipid doses (2.2 vs 2.1 g . kg . day). Using a generalized estimating equations approach, conjugated bilirubin trajectory was found to be lower in patients on ML compared with SL (P < 0.001), suggesting that prolonged exposure (>=4 weeks) to ML is associated with decreased liver injury compared with SL in hospitalized children.

AB - This document serves as an update of the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition (NASPGHAN) and the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) 2009 clinical guidelines for the diagnosis and management of gastroesophageal reflux disease (GERD) in infants and children and is intended to be applied in daily practice and as a basis for clinical trials. Eight clinical questions addressing diagnostic, therapeutic and prognostic topics were formulated. A systematic literature search was performed from October 1, 2008 (if the question was addressed by 2009 guidelines) or from inception to June 1, 2015 using Embase, MEDLINE, the Cochrane Database of Systematic Reviews and the Cochrane Central Register of Controlled Clinical Trials. The approach of the Grading of Recommendations Assessment, Development and Evaluation (GRADE) was applied to define and prioritize outcomes. For therapeutic questions, the quality of evidence was also assessed using GRADE. Grading the quality of evidence for other questions was performed according to the Quality Assessment of Studies of Diagnostic Accuracy (QUADAS) and Quality in Prognostic Studies (QUIPS) tools. During a 3-day consensus meeting, all recommendations were discussed and finalized. In cases where no randomized controlled trials (RCT; therapeutic questions) or diagnostic accuracy studies were available to support the recommendations, expert opinion was used. The group members voted on each recommendation, using the nominal voting technique. With this approach, recommendations regarding evaluation and management of infants and children with GERD to standardize and improve quality of care were formulated. Additionally, 2 algorithms were developed, 1 for infants <12 months of age and the other for older infants and children. PMID- 29470337 TI - ACOG Publications. PMID- 29470338 TI - ACOG Practice Bulletin No. 192 Summary: Management of Alloimmunization During Pregnancy. AB - When any fetal blood group factor inherited from the father is not possessed by the mother, antepartum or intrapartum fetal-maternal bleeding may stimulate an immune reaction in the mother. Maternal immune reactions also can occur from blood product transfusion. The formation of maternal antibodies, or "alloimmunization," may lead to various degrees of transplacental passage of these antibodies into the fetal circulation. Depending on the degree of antigenicity and the amount and type of antibodies involved, this transplacental passage may lead to hemolytic disease in the fetus and neonate. Undiagnosed and untreated, alloimmunization can lead to significant perinatal morbidity and mortality. Advances in Doppler ultrasonography have led to the development of noninvasive methods of management of alloimmunization in pregnant women. Together with more established protocols, Doppler ultrasound evaluation may allow for a more thorough and less invasive workup with fewer risks to the mother and fetus. Prevention of alloimmunization is addressed in another Practice Bulletin (). PMID- 29470339 TI - ACOG Practice Bulletin No. 193 Summary: Tubal Ectopic Pregnancy. AB - Ectopic pregnancy is defined as a pregnancy that occurs outside of the uterine cavity. The most common site of ectopic pregnancy is the fallopian tube. Most cases of tubal ectopic pregnancy that are detected early can be treated successfully either with minimally invasive surgery or with medical management using methotrexate. However, tubal ectopic pregnancy in an unstable patient is a medical emergency that requires prompt surgical intervention. The purpose of this document is to review information on the current understanding of tubal ectopic pregnancy and to provide guidelines for timely diagnosis and management that are consistent with the best available scientific evidence. PMID- 29470340 TI - ACOG Committee Opinion No. 731 Summary: Group Prenatal Care. AB - Individual prenatal care is intended to prevent poor perinatal outcomes and provide education to women throughout pregnancy, childbirth, and the postpartum period through a series of one-on-one encounters between a woman and her obstetrician or other obstetric care provider. Concerns regarding increasing health care costs, health care provider availability, dissatisfaction with wait times, and the minimal opportunity for education and support associated with the individual care model have given rise to interest in alternative models of prenatal care. One alternative model, group prenatal care, may be beneficial or preferred for some practice settings and patient populations, although individual prenatal care remains standard practice. Group prenatal care models are designed to improve patient education and include opportunities for social support while maintaining the risk screening and physical assessment of individual prenatal care. Bringing patients with similar needs together for health care encounters increases the time available for the educational component of the encounter, improves efficiency, and reduces repetition. Evidence suggests patients have better prenatal knowledge, feel more ready for labor and delivery, are more satisfied with care in prenatal care groups, and initiate breastfeeding more often. There is no evidence that suggests that group prenatal care causes harm. Individual and group care models warrant additional study with a goal of demonstrating differences in outcomes and identifying populations that benefit most from specific care models. PMID- 29470341 TI - Clinical Updates in Women's Health Care Summary: Arthritis. AB - Arthritis is a commonly encountered problem in daily clinical practice, and with an aging population it will be as prevalent as any other chronic illness, such as diabetes mellitus, hypertension, and hypercholesterolemia. Obstetrician gynecologists often encounter patients with arthritic symptoms in their practices. They may find it challenging to identify the underlying cause of arthritis and provide recommendations, as well as provide obstetric care to patients with known arthritis. The monograph will discuss common forms of arthritis, diagnostic testing and appropriate management, and referral of patients who need specialized care. Commonly encountered forms of inflammatory arthritis are discussed in this monograph with special emphasis on diagnosis and management. Management of arthritis in the context of pregnancy and lactation also is discussed. PMID- 29470342 TI - ACOG Practice Bulletin No. 192: Management of Alloimmunization During Pregnancy.

Undiagnosed and untreated, alloimmunization can lead to significant perinatal morbidity and mortality. Advances in Doppler ultrasonography have led to the development of noninvasive methods of management of alloimmunization in pregnant women. Together with more established protocols, Doppler ultrasound evaluation may allow for a more thorough and less invasive workup with fewer risks to the mother and fetus. Prevention of alloimmunization is addressed in another Practice Bulletin (). PMID- 29470343 TI - ACOG Practice Bulletin No. 193: Tubal Ectopic Pregnancy. AB - Ectopic pregnancy is defined as a pregnancy that occurs outside of the uterine cavity. The most common site of ectopic pregnancy is the fallopian tube. Most cases of tubal ectopic pregnancy that are detected early can be treated successfully either with minimally invasive surgery or with medical management using methotrexate. However, tubal ectopic pregnancy in an unstable patient is a medical emergency that requires prompt surgical intervention. The purpose of this document is to review information on the current understanding of tubal ectopic pregnancy and to provide guidelines for timely diagnosis and management that are consistent with the best available scientific evidence. PMID- 29470344 TI - ACOG Committee Opinion No. 731: Group Prenatal Care. AB - Individual prenatal care is intended to prevent poor perinatal outcomes and provide education to women throughout pregnancy, childbirth, and the postpartum period through a series of one-on-one encounters between a woman and her obstetrician or other obstetric care provider. Concerns regarding increasing health care costs, health care provider availability, dissatisfaction with wait times, and the minimal opportunity for education and support associated with the individual care model have given rise to interest in alternative models of prenatal care. One alternative model, group prenatal care, may be beneficial or preferred for some practice settings and patient populations, although individual prenatal care remains standard practice. Group prenatal care models are designed to improve patient education and include opportunities for social support while maintaining the risk screening and physical assessment of individual prenatal care. Bringing patients with similar needs together for health care encounters increases the time available for the educational component of the encounter, improves efficiency, and reduces repetition. Evidence suggests patients have better prenatal knowledge, feel more ready for labor and delivery, are more satisfied with care in prenatal care groups, and initiate breastfeeding more often. There is no evidence that suggests that group prenatal care causes harm. Individual and group care models warrant additional study with a goal of demonstrating differences in outcomes and identifying populations that benefit most from specific care models. PMID- 29470345 TI - Summary of 2017 FDA Public Workshop: Antibody-mediated Rejection in Kidney Transplantation. AB - Despite major advances in understanding the pathophysiology of antibody-mediated rejection (AMR); prevention, diagnosis and treatment remain unmet medical needs. It appears that early T cell-mediated rejection, de novo donor-specific antibody (dnDSA) formation and AMR result from patient or physician initiated suboptimal immunosuppression, and represent landmarks in an ongoing process rather than separate events. On April 12 and 13, 2017, the Food and Drug Administration sponsored a public workshop on AMR in kidney transplantation to discuss new advances, importance of immunosuppressive medication nonadherence in dnDSA formation, associations between AMR, cellular rejection, changes in glomerular filtration rate, and challenges of clinical trial design for the prevention and treatment of AMR. Key messages from the workshop are included in this summary. Distinction between type 1 (due to preexisting DSA) and type 2 (due to dnDSA) phenotypes of AMR needs to be considered in patient management and clinical trial design. Standardization and more widespread adoption of routine posttransplant DSA monitoring may permit timely diagnosis and understanding of the natural course of type 2 and chronic AMR. Clinical trial design, especially as related to type 2 and chronic AMR, has specific challenges, including the high prevalence of nonadherence in the population at risk, indolent nature of the process until the appearance of graft dysfunction, and the absence of accepted surrogate endpoints. Other challenges include sample size and study duration, which could be mitigated by enrichment strategies. PMID- 29470346 TI - Utilisation of declined liver grafts yields comparable transplant outcomes and previous decline should not be a deterrent to graft use. AB - BACKGROUND: In the United Kingdom, up to 20% of liver graft offers are not utilized for transplantation and the reasons for graft refusal are multi factorial and not consistent amongst transplant units. METHODS: Liver grafts previously declined by other transplant centers in UK but transplanted in our unit in Birmingham between 2011 and 2015 were analyzed. According to the indicated reason for previous declines, liver grafts were categorized into 3 refusal groups: "quality", "logistics" and "other reasons". Results were compared to a matched, low risk cohort of livers primarily accepted and transplanted at our center. RESULTS: During the study period, 206 livers (DBD: n=141 (68.4%); DCD: n=65 (31.6%) were transplanted, which were previously discarded by a median of 4 other UK centres. The majority of declines were donor quality (n=102; 49.5%) refusals followed by logistics (n=45; 21.8%) and other reasons (n=59; 28.6%). Transplantation from both graft types (DBD and DCD) and all 3 refusal groups achieved equally good outcomes with an overall low complication rate. The incidence of primary-non-function (PNF, 2.4%vs.1.7%; p=0.5483), in-hospital mortality (6.3%vs.4.1%; p=0.2293) and 3-year graft (82.5% vs. 84.1%; p=0.6872)- and patient (85.4%vs.87.6%; p=0.8623) survival was comparable between livers previously declined and livers primarily accepted and transplanted at our centre. CONCLUSION: Transplantation of declined livers can achieve comparable outcomes to primary liver low risk graft offers. Previous refusal should not be taken as a barrier to use the graft and with appropriate recipient selection more lives could be saved. PMID- 29470347 TI - Establishing a Core Outcome Measure for Graft Health: A Standardized Outcomes in Nephrology-Kidney Transplantation (SONG-Tx) Consensus Workshop Report. AB - BACKGROUND: Graft loss, a critically important outcome for transplant recipients, is variably defined and measured, and incompletely reported in trials. We convened a consensus workshop on establishing a core outcome measure for graft loss for all trials in kidney transplantation. METHODS: Twenty-five kidney transplant recipients/caregivers and 33 health professionals from 8 countries participated. Transcripts were analyzed thematically. RESULTS: Five themes were identified. "Graft loss as a continuum" conceptualizes graft loss as a process, but requiring an endpoint defined as a discrete event. In "defining an event with precision and accuracy," loss of graft function requiring chronic dialysis (minimum, 90 days) provided an objective and practical definition; retransplant would capture preemptive transplantation; relisting was readily measured but would overestimate graft loss; and allograft nephrectomy was redundant in being preceded by dialysis. However, the thresholds for renal replacement therapy varied. Conservative management was regarded as too ambiguous and complex to use routinely. "Distinguishing death-censored graft loss" would ensure clarity and meaningfulness in interpreting results. "Consistent reporting for decision making" by specifying time points and metrics (ie time to event) was suggested. "Ease of ascertainment and data collection" of the outcome from registries could support use of registry data to efficiently extend follow-up of trial participants. CONCLUSIONS: A practical and meaningful core outcome measure for graft loss may be defined as chronic dialysis or retransplant, and distinguished from loss due to death. Consistent reporting of graft loss using standardized metrics and time points may improve the contribution of trials to decision making in kidney transplantation. PMID- 29470348 TI - Predicting Expected Organ Donor Numbers in Australian Hospitals Outside of the Donate-Life Network Using the ANZICS Adult Patient Database. AB - BACKGROUND: The majority of organ donations in Australia occur in the DonateLife Network of hospitals, but limited monitoring at other sites may allow donation opportunities to be missed. Our aim was to estimate expected donor numbers using routinely collected data from the Australian and New Zealand Intensive Care Society Adult Patient Database and determine whether unrecognized potential donors might exist in non-DonateLife hospitals. METHODS: All deaths at 150 Australian intensive care units (ICUs) contributing to the Australian and New Zealand Intensive Care Society Adult Patient Database were analyzed between January 2010 and December 2015. Donor numbers were extracted from the Australian and New Zealand Organ Donor registry. A univariate linear regression model was developed to estimate expected donor numbers in DonateLife hospitals, then applied to non-DonateLife hospitals. RESULTS: Of 33 614 deaths at 71 DonateLife hospitals, 6835 (20%) met criteria as "ICU deaths potentially suitable to be donors," and 1992 (6%) were actual donors. There was a consistent relationship between these groups (R = 0.626, P < 0.001) allowing the development of a prediction model which adequately estimated expected donors. Of 8077 deaths in 79 non-DonateLife ICUs, 452 (6%) met criteria as potentially suitable donors. Applying the prediction model developed in DonateLife hospitals, the estimated expected donors in non-DonateLife hospitals was 130. However, there were only 75 actual donors. CONCLUSIONS: It is possible to estimate the expected number of Australian organ donors using routinely collected registry data. These findings suggest that there may be a small but significant pool of underutilized potential donors in non-DonateLife hospitals. This may provide an opportunity to increase donation rates. PMID- 29470349 TI - Impaired Secretion of TNF-alpha by Monocytes Stimulated With EBV Peptides Associates With Infectious Complications After Kidney Transplantation. AB - BACKGROUND: The successful development of immunosuppressive agents has paradoxically led to an era in which adverse effects of immunosuppression, such as infections and cancer, are now a major concern in solid organ recipients. Nevertheless, the main focus of immune monitoring research remains the identification of rejection. There is currently no clinical tool to assess the net state of immunosuppression or to identify patients at increased risk of infectious complications. METHODS: We report a prospective, longitudinal study in which we conducted detailed phenotyping of over 300 peripheral blood mononuclear cell samples from 45 kidney recipients during the first 24 months posttransplant. Patients were classified as cases or controls according to the following events: an opportunistic infection, recurring bacterial infections, or de novo neoplasia. RESULTS: Using a training cohort, an exploratory analysis revealed that the TNFalpha response to synthetic Epstein-Barr virus peptides by CD14CD16 monocytes was lower in cases. A classifier rule based on 2 or greater consecutive values below a threshold of 73% of TNFalpha-positive cells provided a sensitivity and specificity of 83%. In the validation cohort, the assay exhibited a sensitivity of 90% and a specificity of 63%. Analysis of IFNgamma responses by T cells showed no correlation with the cases' phenotype. The association between overimmunosuppression status and the monocyte response was independent of age, renal function, and immunosuppressive regimen. CONCLUSIONS: These data suggest that patients with infectious complications posttransplantation have lower CD14CD16 monocyte responses to Epstein-Barr virus peptides. This assay seems promising to help personalize the immunotherapy. PMID- 29470350 TI - Analysis of Luminex-based Algorithms to Define Unacceptable HLA Antibodies in CDC crossmatch Negative Kidney Transplant Recipients. AB - BACKGROUND: HLA-specific antibodies detected by solid phase assays are increasingly used to define unacceptable HLA antigen mismatches (UAM) before renal transplantation. The accuracy of this approach is unclear. METHODS: Day of transplant sera from 211 complement-dependent cytotoxicity crossmatch-negative patients were retrospectively analyzed for donor-specific anti-HLA antibodies (DSA) using Luminex technology. HLA were defined as UAM if DSA had mean fluorescence intensity above (I) 3000 (patients retransplanted and those with DSA against HLA class I and II) or 5000 (all other patients), (II) 5000 for HLA-A, B, and -DR and 10 000 for HLA DQ or (III) 10 000 (all HLA). We then studied the accuracy of these algorithms to identify patients with antibody-mediated rejection (AMR) and graft loss. UAM were also determined in 256 transplant candidates and vPRA levels calculated. RESULTS: At transplantation, 67 of 211 patients had DSA. Of these, 31 (algorithm I), 24 (II) and 17 (III) had UAM. Nine (I and II) and 8 (III) of 11 early AMR episodes and 7 (I), 6 (II) and 5 (III) of 9 graft losses occurred in UAM-positive patients during 4.9 years of follow-up. Algorithms I and II identified patients with persistently lower glomerular filtration rate even in the absence of overt AMR. Of the waiting list patients, 22-33% had UAM with median virtual panel reactive antibody of 69.2% to 79.1%. CONCLUSIONS: Algorithms I and II had comparable efficacy but were superior to Algorithm III in identifying at-risk patients at an acceptable false-positive rate. However, Luminex-defined UAM significantly restrict the donor pool of affected patients, which might prolong waiting time. PMID- 29470351 TI - Severe Unresolved Cholestasis Due to Unknown Etiology Leading to Early Allograft Failure Within the First 3 Months of Liver Transplantation. AB - BACKGROUND: Causes of severe cholestasis after liver transplantation (LT) are multi-factorial. Although the etiology is predictable in some, others culminate in graft/patient loss without a definitive cause identified. Severe cholestasis is usually associated with overlapped histological findings of rejection and biliary features, and diagnostic interpretation may pose a challenge. METHODS: This is 10-year retrospective analysis of patients with unexplained severe cholestasis resulting in death/graft loss within 90 days of LT. Of 1 583 LT during the study period, 90-day graft failure occurred in 129 (8%) cases; a total of 45 (3%) patients had unresolving severe cholestasis (bilirubin, >100 MUmol/L; alkaline phosphatase, >400 UI/L after 15 days from LT), excluding those due to primary nonfunction/sepsis/vascular causes (n = 84). Demographics, allograft biopsies, radiological investigations, and clinical outcome were analyzed. RESULTS: All patients had persistent abnormal liver biochemistry. Doppler ultrasound scan was normal in all cases. Thirty-five (78%) recipients had at least 1 allograft biopsy (2 [1-9]). On the first biopsy, 22 (63%) patients had acute rejection, 4 (18%) early-chronic rejection, 12 (34%) antibody-mediated rejection. In subsequent biopsies chronic rejection was evident in 5 (14%) cases. Donor-specific antibodies were detected in all patients tested. Biliary anatomy was studied in detail in 9 (20%) patients, all presenting biliary strictures. The majority (n = 39; 87%) died within 32 (10-91) days, only survivors were from retransplantation (n = 3;6.5%) and biliary intervention (n = 3;6.5%). CONCLUSIONS: Unresolving severe cholestasis after LT is a key parameter predicting patient/allograft outcome. Histologically, rejection seems to overlap with biliary strictures; hence, allograft biopsy with signs of rejection should not be a reason to overlook biliary problems, in particular when biliary features are present. Only extensive radiological investigation/intervention or retransplantation prevents patient/allograft loss. PMID- 29470352 TI - Intraoperative Management of Liver Transplant Patients Without the Routine Use of Renal Replacement Therapy. AB - BACKGROUND: Renal failure is common among patients undergoing liver transplantation. Liver allocation based on the model for end-stage liver disease score has increased the number of recipients who require perioperative renal replacement therapy (RRT). Although RRT can be continued intraoperatively, the risks and benefits of intraoperative RRT are not well defined. The aim of this study is to report the intraoperative management of patients with pretransplant renal failure at a transplant center with extremely infrequent utilization of intraoperative RRT. MATERIALS AND METHODS: We performed a retrospective analysis of all adult patients undergoing orthotopic liver or simultaneous liver-kidney (SLK) transplantation between June 2009 and December 2015. Patients were divided into 2 groups based on their need for pretransplant RRT. RESULTS: A total of 785 patients underwent liver or SLK transplant during the study period. One hundred and seventy-four patients (22.2%) required preoperative dialysis. Only 2 patients required intraoperative RRT. There was no difference in the incidence of acidosis or hyperkalemia between patients who required preoperative dialysis and those who did not. CONCLUSIONS: We describe the successful management of patients undergoing liver or SLK transplantation almost entirely without the need for intraoperative RRT. PMID- 29470353 TI - Clinical Efficacy of Percutaneous Transhepatic Portal Vein Angioplasty for Late onset Portal Vein Stenosis in Pediatric Liver Transplant Patients. AB - BACKGROUND: Stenosis of the portal vein (PV) is a rare complication after liver transplantation (LT) in pediatric patients, and it adversely affects outcomes. We reviewed the safety and efficacy of percutaneous transhepatic balloon angioplasty (PTBA) as a treatment for post-LT late-onset PV stenosis (PVS). METHODS: Three hundred eighteen patients between the ages of 0 and 21 years received an LT from 2001 to 2016 at this tertiary center. Twenty-one children were evaluated for PVS using percutaneous portal venography. RESULTS: Of the 21, 19 patients (7 female, 12 male) with a median age of 12 years (7-15 years) were diagnosed with PVS and received PTBA. Two patients were excluded: one did not have PVS, and one received shunt surgery. Median time between LT and PTBA was 83 months (interquartile range, 49-138). For patients in whom pressure could be accurately measured (n = 9), mean PV pressure gradient was 6.3 mm Hg (SD, 5.0) preprocedure and 0.9 mm Hg (SD, 1.2) postprocedure. Mean percentage improvement in gradient across the stenotic region was 86.2% (SD, 15.9%; P < 0.01). At 12-month postprocedure, there was a mean improvement (pre-PTBA vs post-PTBA means) in bilirubin by 28.2% (0.6 mg/dL vs 0.4 mg/dL, P = 0.07), aspartate aminotransferase by 31.2% (116.3 IU/L vs 28.1 IU/L, P = 0.04), alanine aminotransferase by 40.7% (140.3 IU/L vs 28.6 IU/L, P = 0.07), gamma-glutamyltransferase by 29.0% (337.2 IU/L vs 38.0 IU/L, P = 0.06) and platelets by 62.1% (128.3 vs 191.1 * 10/L, P = 0.03). The PV patency was successfully maintained in 18 of 19 patients for a median of 16 months (interquartile range, 5-35). One patient received a successful repeat procedure for restenosis at 6 weeks. CONCLUSION: Angioplasty for PVS after pediatric LT is a safe and effective treatment with good patency and improved clinical outcomes. Longer follow-up studies are required. PMID- 29470354 TI - Poor Survival after Retransplantation in NASH cirrhosis. AB - BACKGROUND: Nonalcoholic steatohepatitis (NASH) cirrhosis is a common indication for liver transplantation (LT) in the U.S. There is a paucity of data on retransplantation (re-LT) in those who were initially transplanted for NASH. METHODS: We queried the UNOS data sets from 2002-2016 to analyze the outcomes of adults with NASH (n=128) and compared them to groups that received re-LT for cryptogenic cirrhosis (CC, n=189), alcoholic cirrhosis (AC, n=300) or autoimmune hepatitis cirrhosis (AIH-C, n=118) after excluding multiple-organ re-LT and individuals with HCC. We estimated survival probabilities using a Kaplan-Meier estimator, and a relative risk of patient and graft mortality using proportional hazards regression. RESULTS: The NASH group was older and had a higher prevalence of obesity, type II diabetes mellitus, renal insufficiency, portal vein thrombosis, and poor performance status. The median interval between 1st and 2nd LT was shorter in the NASH group (27 days). The graft and patient 5-year survival rates were lower for the NASH group after re-LT compared to the other 3 groups. After adjusting for demographic and disease complication factors, the factors that increased a risk of patient or graft failure were a poor performance status (HR=1.64 [1.19-2.26]), donor risk index (HR= 1.51 [1.08-2.12]) and a high MELD score (HR= 1.02 [1.00-1.04]). CONCLUSIONS: Despite the comparable outcomes reported for initial LT among the various etiologies, the outcome of re-LT is significantly worse for NASH cirrhosis. PMID- 29470355 TI - Effects of Warm Versus Cold Ischemic Donor Lung Preservation on the Underlying Mechanisms of Injuries During Ischemia and Reperfusion. AB - BACKGROUND: Ischemia-reperfusion injury related to lung transplantation is a major contributor to early postoperative morbidity and mortality. We hypothesized that donation after cardiac death donor lungs experience warm ischemic conditions that activate different injurious mechanisms compared with donor lungs that undergo prolonged cold ischemic conditions. METHODS: Rat donor lungs were preserved under different cold ischemic times (CIT) (12 hours or 18 hours), or under warm ischemia time (WIT) (3 hours) after cardiac death, followed by single left lung transplantation. Lung function was analyzed during the 2-hour reperfusion period. Microscopic injury, cell death, energy status, and inflammatory responses were assessed. RESULTS: Pulmonary oxygenation function was significantly worse in both 18hCIT and WIT groups, accompanied by higher peak airway pressure, acute lung injury scores, and expression of cell death markers compared with the 12hCIT control group. In lung tissue, reperfusion induced increased expression levels of interleukin (IL)-1alpha, IL-1beta, IL-6, and chemokines CCL2, CCL3, CXCL1, and CXCL2 in CIT lungs. Notably, these changes were much lower in the WIT group. Additionally, plasma levels of IL-6, IL-18, CCL2, and vascular endothelial growth factor were significantly higher, and adenosine triphosphate levels were significantly reduced in warm versus cold ischemic lungs. CONCLUSIONS: Compared with 12hCIT, posttransplant pathophysiology deteriorated similarly in both 18hCIT and WIT groups. However, tissue adenosine triphosphate levels and inflammatory profiling differed between warm versus cold ischemic donor lungs. These differences should be carefully considered when developing specific therapeutic strategies to reduce ischemia-reperfusion injury in lung transplantation. PMID- 29470356 TI - Donor Club Cell Secretory Protein G38A Polymorphism Is Associated With a Decreased Risk of Primary Graft Dysfunction in the French Cohort in Lung Transplantation. AB - BACKGROUND: Club Cell Secretory Protein (CCSP) G38A polymorphism has recently been involved in lung epithelial susceptibility to external injuries. Lung transplantation (LT) is currently limited by ischemia-reperfusion injury leading to primary graft dysfunction (PGD). We thus hypothesized that donor CCSP G38A polymorphism might impact the risk of PGD after LT. METHODS: We focused on LT included in the French multicentric Cohort in Lung Transplantation (COLT), performed between January 2009 and December 2014, and associated with preoperative blood samples from the donor and the recipient. Characteristics of the donors, recipients, procedures, early and late outcomes were prospectively recorded in COLT. The CCSP serum concentration and CCSP gene G38A polymorphism were retrospectively determined in a blind manner. Their association with grade 3 PGD was studied in univariate and multivariate analysis. RESULTS: The study group included 104 LT donors and recipients, 84 with grade 0 to 2 PGD and 20 with grade 3 PGD. Preoperative CCSP serum concentration was significantly higher in the donors (median, 22.54 ng/mL; interquartile range, 9.6-43.9) than in the recipients (median, 7.03 ng/mL; interquartile range, 0.89-19.2; P < 0.001) but none impacted the risk of grade 3 PGD (P = 0.93 and P = 0.69, respectively). Donor CCSP G38A polymorphism was associated with a decreased risk of grade 3 PGD in univariate (AG + AA 3/21 = 14.2% vs GG 10/26 = 38.4%, P = 0.044) and multivariate analysis (odds ratio associated with AG + AA, 0.22; 95% confidence interval, 0.041-0.88; P = 0.045), but recipient CCSP G38A polymorphism was not. CONCLUSIONS: Donor CCSP G38A polymorphism is associated with a decreased risk of severe PGD after LT in the COLT study. These findings should be confirmed in the frame of a prospective study. PMID- 29470357 TI - Validation of the alpha-fetoprotein Model for Hepatocellular Carcinoma Recurrence After Transplantation in an Asian Population. AB - BACKGROUND: This study was designed to validate the alpha-fetoprotein model for predicting recurrence after liver transplantation in Korean hepatocellular carcinoma patients. METHODS: Patients who underwent liver transplantation for hepatocellular carcinoma at Samsung Medical Center between 2007 and 2015 were included. Recurrence, overall survival, and disease-specific survival of patients divided by both the Milan criteria and the alpha-fetoprotein model were compared using Kaplan-Meier log-rank test. The predictability of the alpha-fetoprotein model compared with the Milan criteria was tested by means of net reclassification improvement analysis applied to patients with a follow-up of at least 2 years. RESULTS: A total of 400 patients were included in the study. Patients within Milan criteria had 5-year recurrence, and overall survival rates of 20.9% and 76.3%, respectively, compared with corresponding rates of 50.3% and 55.7%, respectively, for patients who were beyond Milan criteria. alpha Fetoprotein model low-risk patients had 5-year recurrence and overall survival rates of 21.1% and 76.2%, respectively, compared with corresponding rates of 57.7% and 52.2%, respectively, in high-risk patients (P < 0.001, all). Although overall net reclassification improvements were statistically nonsignificant for recurrence (net reclassification improvements [NRI] = 1.7%, Z = 0.30, P = 0.7624), and overall survival (NRI = 9.0%, Z = 1.60, P = 0.1098), they were significantly better for predicting no recurrence (NRI = 6.6%, Z = 3.16, P = 0.0016) and no death. (NRI = 7.7%, Z = 3.65, P = 0.0003). CONCLUSIONS: The alpha fetoprotein model seems to be a promising tool for liver transplantation candidacy, but further investigation is needed. PMID- 29470359 TI - CD44 Deficiency in Mice Protects the Heart Against Angiotensin II-Induced Cardiac Fibrosis. AB - This study tested the hypothesis that CD44 is involved in development of cardiac fibrosis via angiotensin II (Ang II) AT1 receptor stimulated TNFalpha/NFkappaB/IkappaB signaling pathways. Study was conducted in C57BL/6 wild type and CD44 knockout mice subjected to Ang II infusion (1000 ng/kg/min) using osmotic minipumps up to 4 weeks or with gastric gavage administration of the AT1 receptor blocker, telmisartan at a dose of 10 mg/kg/day. Results indicated that Ang II enhances expression of the AT1 receptor, TNFalpha, NFkappaB and CD44 as well as downregulates IkappaB. Further analyses revealed that Ang II increases macrophage migration, augments myofibroblast proliferation and induces vascular/interstitial fibrosis. Comparison of the Ang II group, treatment with telmisartan significantly reduced expression of the AT1 receptor and TNFalpha. These changes occurred in coincidence with decreased NFkappaB, increased IkappaB and downregulated CD44 in the intracardiac vessels and intermyocardium. Furthermore, macrophage migration and myofibroblast proliferation were inhibited and fibrosis was attenuated. Knockout of CD44 did not affect Ang II stimulated AT1 receptor and modulated TNFalpha/NFkappaB/IkappaB signaling, but significantly reduced macrophage/myofibroblast mediated fibrosis as identified by less extensive collagen-rich area. These results suggest that the AT1 receptor is involved in the development of cardiac fibrosis by stimulating TNFalpha/NFkappaB/IkappaB triggered CD44 signaling pathways. Knockout of CD44 blocked Ang II induced cell migration/proliferation and cardiac fibrosis. Therefore, selective inhibition of CD44 may be considered as a potential therapeutic target for attenuating Ang II induced deleterious cardiovascular effects. PMID- 29470358 TI - Is Vulvovaginal Lichen Planus Associated With Squamous Cell Carcinoma? AB - OBJECTIVE: The aim of the study was to assess for the presence of vulvar lichen planus (LP) in association with human papillomavirus (HPV)-independent squamous cell carcinoma (SCC). MATERIALS AND METHODS: We performed a clinicohistopathologic review of consecutive vulvectomies and wide local excisions for HPV-independent vulvar or vaginal SCC from 2007 to 2017. Data collected included site of SCC, adjacent precursor lesions and dermatoses, dermatologic treatment, and outcome. RESULTS: There were 43 cases of primary HPV independent vulvar SCC treated by excision, but no vaginal cancers. Eighteen women (42%) had a preoperative diagnosis of lichen sclerosus (LS); none had a diagnosis of LP. Topical corticosteroids were prescribed in 19 (44%) of 43, with 4 women placed on maintenance therapy. Tumors arose from the labia minora, labia majora, and periclitoris, but not from vestibule or perianus. On histopathological review, LS was present in 41 (95%) of 43 specimens, 1 had a nonspecific lichenoid reaction, and 1 had lichen simplex; both of the latter had subsequent biopsies showing LS. Lichen planus was not seen in association with SCC. Differentiated vulvar intraepithelial neoplasia (dVIN) was present in 38 (88%) of 43 specimens, whereas 1 had acanthosis with altered differentiation and 4 (9%) had no precursor lesion. Differentiated vulvar intraepithelial neoplasia had standard, basaloid, and hypertrophic morphology, superficially resembling erosive LP in 9 (24%) of 38 and hypertrophic LP in 6 (16%) of 38. CONCLUSIONS: Lichen planus was not seen in association with HPV-independent vulvar SCC, whereas LS was underrecognized and inadequately treated in this group. Pathologists should be aware that dVIN may superficially resemble erosive or hypertrophic LP. PMID- 29470360 TI - Oral Supplementation with Bovine Colostrum Prevents Septic Shock and Brain Barrier Disruption During Bloodstream Infection in Preterm Newborn Pigs. AB - Preterm infants have increased risk of neonatal sepsis, potentially inducing brain injury, and they may benefit from early initiation of enteral milk feeding. Using preterm pigs as models, we hypothesized that early provision of bovine colostrum to parentally nourished newborns protects against sepsis and neuroinflammation during bloodstream infection. Preterm newborn pigs were administered 10 CFU/kg of intra-arterial Staphylococcus epidermidis (SE, an opportunistic pathogen often causing sepsis in preterm infants), followed by administration of total parenteral nutrition (TPN, SE + TPN, n = 15) or oral provision of bovine colostrum with supplementary parenteral nutrition (SE + COL, n = 14), and compared with uninfected, TPN-nourished controls (CON + TPN, n = 11). SE-infected animals showed multiple signs of sepsis, including lethargy, hypotension, respiratory acidosis, internal organ hemorrhages, cellular responses (leukopenia, thrombocytopenia), brain barrier disruption and neuroinflammation. At 24 h, colostrum supplementation reduced the SE abundance in blood and cerebrospinal fluid (CSF, both p < 0.05). Further, colostrum feeding normalized arterial blood pressure (38.5 +/- 1.20 vs 30.6 +/- 3.79 mmHg), pH (7.37 +/- 0.02 vs 7.10 +/- 0.07) and lactate (1.01 +/- 0.11 vs 4.20 +/- 1.20 mM, all p < 0.05), and increased motor activity, to levels in controls (p < 0.001). Finally, colostrum-fed animals showed reduced blood-CSF barrier permeability and CSF leukocyte levels, and this was accompanied by normalized gene expression of tight junction proteins (Occludin, Claudin-5, both p < 0.05) and reduced expression of leukocyte chemoattractants (CXCL9-11, all p < 0.01). Early oral supplementation with bovine colostrum prevents septic shock and ameliorates brain barrier disruption and neuroinflammation during bloodstream infection in preterm pigs. Bovine colostrum supplementation may improve resistance against systemic infection in immature, immune-compromised preterm infants. PMID- 29470361 TI - Early Heterogenic Response of Renal Microvasculature to Hemorrhagic Shock/Resuscitation and the Influence of NF-kappaB Pathway Blockade. AB - Hemorrhagic shock (HS) is associated with low blood pressure due to excessive loss of circulating blood and causes both macrocirculatory and microcirculatory dysfunction. Fluid resuscitation after HS is used in the clinic to restore tissue perfusion. The persistent microcirculatory damage caused by HS and/or resuscitation can result in multiple organ damage, with the kidney being one of the involved organs. The kidney microvasculature consists of different segments that possess a remarkable heterogeneity in functional properties. The aim of this study was to investigate the inflammatory responses of these different renal microvascular segments, i.e., arterioles, glomeruli, and postcapillary venules, to HS and resuscitation (HS/R) in mice and to explore the effects of intervention with an NF-kappaB inhibitor on these responses. We found that HS/R disturbed the balance of the Angiopoietin-Tie2 ligand-receptor system, especially in the glomeruli. Furthermore, endothelial adhesion molecules, pro-inflammatory cytokines, and chemokines were markedly upregulated by HS/R, with the strongest responses occurring in the glomerular and postcapillary venous segments. Blockade of NF-kappaB signaling during the resuscitation period only slightly inhibited HS/R induced inflammatory activation, possibly because NF-kappaB p65 nuclear translocation already occurred during the HS period. In summary, although all three renal microvascular segments were activated upon HS/R, responses of endothelial cells in glomeruli and postcapillary venules to HS/R, as well as to NF-kappaB inhibition were stronger than those in arterioles. NF-kappaB inhibition during the resuscitation phase does not effectively counteract NF-kappaB p65 nuclear translocation initiating inflammatory gene transcription.This is an open access article distributed under the terms of the Creative Commons Attribution Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

PMID- 29470362 TI - An Evaluation of Supramaximally Loaded Eccentric Leg Press Exercise. AB - Harden, M, Wolf, A, Russell, M, Hicks, KM, French, D, and Howatson, G. An evaluation of supramaximally loaded eccentric leg press exercise. J Strength Cond Res 32(10): 2708-2714, 2018-High-intensity eccentric exercise is a potent stimulus for neuromuscular adaptation. A greater understanding of the mechanical stimuli afforded by this exercise will aid the prescription of future eccentric training regimens. This study sought to investigate the mechanical characteristics of supramaximally loaded eccentric exercise when using a custom built leg press machine. Using a within-subject, repeated-measures design, 15 strength trained subjects (age, 31 +/- 7 years; height, 180.0 +/- 6.8 cm; body mass, 81.5 +/- 13.9 kg) were assessed under 3 different conditions: low (LO), moderate (MOD), and high (HI) intensity, which were equivalent in intensity to 110, 130, and 150%, respectively, of peak force during an isometric maximal voluntary contraction (IMVC) performed on leg press at 90 degrees knee flexion. All loading conditions demonstrated a similar pattern of mechanical profile; however, the variables underpinning each profile showed significant (p < 0.01) load-dependent response (LO vs. MOD, MOD vs. HI, LO vs. HI) for all variables, except for average acceleration. Average force associated with each loading conditions exceeded IMVC but equated to a lower intensity than what was prescribed. Repetitions under higher relative load intensity stimulated greater average force output, faster descent velocity, greater magnitude of acceleration, shorter time under tension, and a decline in force output at the end range of motion. This research provides new data regarding the fundamental mechanical characteristics underpinning supramaximally loaded eccentric leg press exercise. The information gathered in the study provides a foundation for practitioners to consider when devising loading strategies and implementing or evaluating supramaximally loaded eccentric exercise when using a similar exercise and device.

AB - The purpose of the present study was to compare the anthropometric and performance profiles of division I (D1) and division II (D2) Italian field hockey players.Fifteen DI players and fifteen D2 players (age = 25.4 +/- 5.2 y; body mass = 78.5 +/- 9.0 kg; body height = 179.6 +/- 7.8 cm) were assessed on one occasion for anthropometry, body composition, physiological measurements and sport-specific skills. Differences between the two groups were evaluated using a one-way analysis of variance. Pearson correlations were used to examine relationships between the different measurements.Significantly (p = 0.039) lower percentages of body fat were found on D1 group compared to D2 group (-3.5%). A significant difference between the groups were noted for shooting accuracy (p = 0.013), with the D1 group performing 14.5 % better than the DII group. No significant differences between the groups were found for shooting speed (p = 0.103), slalom and dribbling performances (p = 0.292 and p = 0.416, respectively). Physiological assessments did not show any significant differences between the groups. Large correlations (r = 0.73; p < 0.001) were found between shooting speed and accuracy. Moderate correlations were observed between the shooting speed and the hand grip strength, in particular of the left hand (r = 0.61; p = 0.007).Results of the present study indicate that the difference between D1 and D2 players may be more related to technical factors than to physical fitness. Ball control however, may not be a limiting factor in D2 players. PMID- 29470364 TI - Resistance Training Is Associated With Higher Bone Mineral Density Among Young Adult Male Distance Runners Independent of Physiological Factors. AB - Duplanty, AA, Levitt, DE, Hill, DW, McFarlin, BK, DiMarco, NM, and Vingren, JL. Resistance training is associated with higher bone mineral density among young adult male distance runners independent of physiological factors. J Strength Cond Res 32(6): 1594-1600, 2018-Low bone mineral density (BMD) in male distance runners is common and could be modulated by a host of biomarkers involved in the dynamic balance of bone tissue. In contrast, resistance training can increase BMD; however, the efficacy of resistance training in protecting BMD in distance runners has not been elucidated. The aim of this study was to investigate the relationship between resistance training, testosterone and bone metabolism biomarker concentrations, and BMD in young adult male distance runners. Twenty five apparently healthy men (23-32 years; mean +/- SD: 25.9 +/- 2.9 years; 1.77 +/- 0.04 m; 75.4 +/- 8.5 kg) were categorized into 1 of 3 groups: untrained control participants (CON; n = 8); nonresistance-trained runners (NRT; n = 8); or resistance-trained runners (RT; n = 9). Blood was collected and analyzed for concentrations of free and total testosterone and 14 bone metabolism biomarkers. Bone mineral density was assessed using dual-energy X-ray absorptiometry. At all measured sites, BMD was greater (p <= 0.05) for RT compared with NRT and CON. Vitamin D concentration was greater (p <= 0.05) in RT and NRT compared with CON. Concentrations of testosterone and remaining bone biomarkers did not differ between groups (p > 0.05). Resistance-trained runners had greater BMD than nonresistance-trained runners and untrained peers. This difference did not seem to be modulated by biomarkers that contribute to bone formation or resorption, indicating that differences in BMD are associated with habitual load-bearing exercise using external resistance. Runners should perform resistance exercise at least once per week because this is associated with greater BMD. PMID- 29470365 TI - Effect of Acute Complex Training on Upper Body Force and Power in Collegiate Wrestlers. AB - To determine if chain bench press (BP) exercise would enhance acute upper body force and power, 13 collegiate male wrestlers (mean +/- SD; 20.5 +/- 1 years; 174.3 +/- 4.2 cm; 76.5 +/- 8.3 kg) with >= 1 year of strength training participated. Session 1 included body composition ((BodPod) 8.5 +/- 2.6 %body fat)), 3 repetition maximum (RM) BP, and familiarization with the plyometric push up (PPU) on a force plate. Athletes were matched for 3RM BP and randomly assigned to one of two groups: Chain BP or Plate BP. One week after Session 1, athletes performed the experimental protocol which consisted of: Baseline PPU, Chain/Plate BP Set 1 (6 reps @ 60%), 30 sec rest, PPU, 3 min rest, Chain/Plate BP Set 2 (6 reps @60%), 30 sec rest, and PPU. Independent samples t-tests analyzed physical characteristics (p<0.05). Standardized magnitude-based inferences were used to define outcomes. Aside from age (Plate BP 21.4 +/- 0.8, Chain BP 19.9 +/-0.7 years), no physical differences were observed. Performance of Chain BP and Plate BP resulted in a likely (likelihoods of benefit/trivial/harm relative to the threshold for a smallest worthwhile benefit of 89 W: 0.5/9.2/90.3) and very likely (0.1/0.8/99.1) negative effect on peak power output in the PPU following Set 1. Chain BP resulted in a likely positive effect on peak force in the PPU following Set 1 (smallest worthwhile benefit 13 N: 82.8/16.9/0.3) and Set 2 (94.7/5.2/0.1). Chain BP did not result in higher upper body power over traditional plate loaded resistances. PMID- 29470366 TI - Impact of angiotensin-converting enzyme inhibition on platelet tissue factor expression in stroke-prone rats. AB - OBJECTIVE: Hypertension is a well known risk factor for thrombotic events such as myocardial infarction and stroke. Platelets express tissue factor (TF), the key activator of blood coagulation and thrombus formation. The number of TF-positive platelets increases in pathological conditions characterized by thrombotic complications but whether this occurs in hypertension is unknown. Here we investigated whether platelet TF expression is increased in a hypertensive status through a mechanism acting on megakaryocytes; the phenomenon could be modulated by antihypertensive drug as captopril; angiotensin (AngII) influences platelet TF expression. METHODS: Spontaneously hypertensive stroke prone (SHRSP) rats received standard diet (StD) or a Japanese high-salt permissive diet (JpD). After 3 weeks, JpD animals were randomized to receive captopril or vehicle. Normotensive Wistar Kyoto (WKY) rats were used as controls. Cell-associated TF expression and activity were analyzed by flow cytometry and calibrated automated thrombogram, respectively. RESULTS: Hypertensive StD-SHRSP showed an increased number of TF-positive platelets compared with normotensive WKY. After JpD administration, SHRSP developed severe hypertension and renal damage; the number of TF-positive megakaryocytes significantly increased compared with StD-SHRSP resulting in a higher number of TF-positive platelets with a faster kinetic of thrombin generation. These effects were reverted by captopril. Ex-vivo stimulation of platelets, isolated from normotensive WKY and from healthy individuals, with AngII induced a concentration-dependent increase of surface associated TF expression. CONCLUSION: The current study shows for the first time that in hypertension the number of TF-positive megakaryocytes increases thus releasing in the circulation more platelets carrying a functionally active TF. AngII stimulates platelets to express TF. PMID- 29470367 TI - What are the cardiovascular effects of the newer classes of drugs for type 2 diabetes?

PMID- 29470371 TI - PA program characteristics and diversity in the profession. AB - OBJECTIVES: The primary objective of this study was to identify PA program characteristics that may be associated with higher or lower percentages of underrepresented minority students in PA programs. METHODS: Data from the Physician Assistant Education Association (PAEA) 2002-2003 and 2012-2013 annual surveys were analyzed. Bivariate correlation coefficients and multiple regression modeling were used to identify relationships between program characteristics and percentages of black and Hispanic students. RESULTS: The percentage of white matriculants in PA programs increased from 76.5% in 2002-2003 to 81.8% in 2012 2013; the percentage of black students decreased from 6.2% to 4.4%. Multiple linear regression revealed a modest negative relationship between master's degree and percentage of underrepresented minority students and a modest positive relationship between percentages of underrepresented minority employees and underrepresented minority students. CONCLUSIONS: Further research is needed to identify strategies to increase underrepresented minority participation in healthcare professions programs. PMID- 29470372 TI - Improving veterans' access to gastroenterology clinical care. AB - At a VA hospital, wait times for gastroenterology care have been in the order of 60 to 90 days for new clinic consults. Through a quality improvement process, these times were reduced to less than 30 days. With a revised triage process, the number of consults needing to be scheduled into the clinic was reduced 34%. In addition to achieving rapid clinical access, the weekly half-day clinic became less congested and more efficient. We describe this process of achieving improved access.

PMID- 29470381 TI - The Business, Ethics, and Quality Cases for Consumer Engagement in Nursing. AB - OBJECTIVE: The aims of this study were to illustrate the quality, safety, cost effectiveness, and ethics of consumer engagement initiatives and identify promising practices and leadership strategies used by nursing leaders. METHODS: A literature review was performed with supplementary interviews conducted with 25 key nursing informants including nursing executives and chief nursing officers at acute care hospitals, community health centers, policy institutions, and quality and safety organizations. A narrative synthesis approach was used to identify and compare existing measures of consumer engagement and compassionate care in acute care settings. One-hour semistructured interviews were performed, and information was gathered by notes and audio recordings. RESULTS: Consumer engagement activities focusing on compassionate patient and provider interactions involving patients and family as partners on the care team are associated with increases in treatment savings and patient safety in terms of length of stay and reduced medication errors. Engagement initiatives support employee health and reduce compassion fatigue. CONCLUSION: Findings illustrate the impact of patients and family engagement in decision making and promising organizational practices that reinforce engagement. PMID- 29470382 TI - A Tool to Identify Key Behaviors and Attributes of High-Performing Nurses. AB - OBJECTIVE: The purpose of this project was to identify key behaviors and attributes that distinguish high-performing nurses to develop a tool for employment screening, staff development, and performance management. BACKGROUND: Selecting nurses who will complement an organization's mission and philosophy is a key step toward achieving quality and safety goals, ensuring patient and family satisfaction, and improving retention rates and overall costs. METHODS: Focus group methodology was used to determine perceptions of high-performing nurses' behaviors and attributes. Content analysis of the meeting transcripts was performed to aggregate data into categories and items. RESULTS: Following several phases of testing with various groups, a 16-item scale has been developed. CONCLUSIONS: This tool has received positive ratings from nurse managers currently using it to interview nurse applicants who best "fit" into the organization's nursing culture. Results will be monitored over time including hiring decisions, preceptor ratings, and retention rates.

PMID- 29470385 TI - An Activity Recognition Framework Deploying the Random Forest Classifier and A Single Optical Heart Rate Monitoring and Triaxial AccelerometerWrist-Band. AB - Wrist-worn sensors have better compliance for activity monitoring compared to hip, waist, ankle or chest positions. However, wrist-worn activity monitoring is challenging due to the wide degree of freedom for the hand movements, as well as similarity of hand movements in different activities such as varying intensities of cycling. To strengthen the ability of wrist-worn sensors in detecting human activities more accurately, motion signals can be complemented by physiological signals such as optical heart rate (HR) based on photoplethysmography. In this paper, an activity monitoring framework using an optical HR sensor and a triaxial wrist-worn accelerometer is presented. We investigated a range of daily life activities including sitting, standing, household activities and stationary cycling with two intensities. A random forest (RF) classifier was exploited to detect these activities based on the wrist motions and optical HR. The highest overall accuracy of 89.6 +/- 3.9% was achieved with a forest of a size of 64 trees and 13-s signal segments with 90% overlap. Removing the HR-derived features decreased the classification accuracy of high-intensity cycling by almost 7%, but did not affect the classification accuracies of other activities. A feature reduction utilizing the feature importance scores of RF was also carried out and resulted in a shrunken feature set of only 21 features. The overall accuracy of the classification utilizing the shrunken feature set was 89.4 +/- 4.2%, which is almost equivalent to the above-mentioned peak overall accuracy. PMID- 29470386 TI - Bioactive Phenolic and Isocoumarin Glycosides from the Stems of Homalium paniculiflorum. AB - Two new phenolic glycosides (1 and 2) and two new isocoumarin glycosides (3 and 4), along with 14 known compounds (5-18), were isolated from the stems of Homalium paniculiflorum. Their structures were established on the basis of extensive spectroscopic analyses and chemical methods. All new compounds were evaluated for their anti-inflammatory activities via examining the inhibitory activity on nitric oxide (NO) production induced by lipopolysaccharide (LPS) in mouse macrophage RAW 264.7 cells in vitro. Compounds 1 and 4 exhibited inhibitory activities with IC50 values of 30.23 +/- 1.23 MUM and 19.36 +/- 0.19 MUM, respectively. PMID- 29470387 TI - Assessment of Chitosan-Based Hydrogel and Photodynamic Inactivation against Propionibacterium acnes. AB - Chitosan (CH) is a biopolymer that exhibits a number of interesting properties such as anti-inflammatory and antibacterial activity and is also a promising platform for the incorporation of photosensitizing agents. This study aimed to evaluate the efficacy of antimicrobial activity of chitosan hydrogel formulation alone and in combination with the methylene blue (MB) associated with antimicrobial photodynamic therapy (aPDT) against planktonic and biofilm phase of Propionibacterium acnes. Suspensions were sensitized with 12.5, 25.0, 37.5, 50.0 MUg/mL of MB for 10 min and biofilms to 75, 100 and 150 MUg/mL for 30 min then exposed to red light (660 nm) at 90 J/cm2 and 150 J/cm2 respectively. After treatments, survival fractions were calculated by counting the number of colony forming units. The lethal effect of aPDT associated with CH hydrogel in planktonic phase was achieved with 12.5 ug/mL MB and 1.9 log10 biofilm reduction using 75 ug/mL MB. Rheological studies showed that formulations exhibited pseudoplastic non-Newtonian behavior without thixotropy. Bioadhesion test evidenced that the formulations are highly adhesive to skin and the incorporation of MB did not influence the bioadhesive force of the formulations. PMID- 29470388 TI - Adolescents' Sexual Wellbeing in Southwestern Uganda: A Cross-Sectional Assessment of Body Image, Self-Esteem and Gender Equitable Norms. AB - Measures of sexual wellbeing and positive aspects of sexuality in the World Health Organization definition for sexual health are rarely studied and remain poorly understood, especially among adolescents in Sub-Saharan Africa. The objective of this study was to assess sexual wellbeing in its broad sense-i.e., body image, self-esteem, and gender equitable norms-and associated factors in young adolescents in Uganda. A cross-sectional survey of adolescents ages 10-14 years in schools was carried out between June and July 2016. Among 1096 adolescents analyzed, the median age was 12 (Inter-Quartile Range (IQR): 11, 13) and 58% were female. Self-esteem and body image scores were high with median 24 (IQR: 22, 26, possible range: 7-28) and median 22 (IQR: 19, 24, possible range: 5 25) respectively. Gender equitable norms mean score was 28.1 (SD 5.2: possible range 11-44). We noted high scores for self-esteem and body image but moderate scores on gender equitable norms. Girls had higher scores compared to boys for all outcomes. A higher age and being sexually active were associated with lower scores on gender equitable norms. Gender equitable norms scores decreased with increasing age of adolescents. Comprehensive and timely sexuality education programs focusing on gender differences and norms are recommended. PMID- 29470389 TI - A Walnut-Enriched Diet Affects Gut Microbiome in Healthy Caucasian Subjects: A Randomized, Controlled Trial. AB - Regular walnut consumption is associated with better health. We have previously shown that eight weeks of walnut consumption (43 g/day) significantly improves lipids in healthy subjects. In the same study, gut microbiome was evaluated. We included 194 healthy subjects (134 females, 63 +/- 7 years, BMI 25.1 +/- 4.0 kg/m2) in a randomized, controlled, prospective, cross-over study. Following a nut-free run-in period, subjects were randomized to two diet phases (eight weeks each); 96 subjects first followed a walnut-enriched diet (43 g/day) and then switched to a nut-free diet, while 98 subjects followed the diets in reverse order. While consuming the walnut-enriched diet, subjects were advised to either reduce fat or carbohydrates or both to account for the additional calories. Fecal samples were collected from 135 subjects at the end of the walnut-diet and the control-diet period for microbiome analyses. The 16S rRNA gene sequencing data was clustered with a 97% similarity into Operational Taxonomic Units (OTUs). UniFrac distances were used to determine diversity between groups. Differential abundance was evaluated using the Kruskal-Wallis rank sum test. All analyses were performed using Rhea. Generalized UniFrac distance shows that walnut consumption significantly affects microbiome composition and diversity. Multidimensional scaling (metric and non-metric) indicates dissimilarities of approximately 5% between walnut and control (p = 0.02). The abundance of Ruminococcaceae and Bifidobacteria increased significantly (p < 0.02) while Clostridium sp. cluster XIVa species (Blautia; Anaerostipes) decreased significantly (p < 0.05) during walnut consumption. The effect of walnut consumption on the microbiome only marginally depended on whether subjects replaced fat, carbohydrates or both while on walnuts. Daily intake of 43 g walnuts over eight weeks significantly affects the gut microbiome by enhancing probiotic- and butyric acid-producing species in healthy individuals. Further evaluation is required to establish whether these changes are preserved during longer walnut consumption and how these are linked to the observed changes in lipid metabolism. PMID- 29470390 TI - Preparation of Fish Skin Gelatin-Based Nanofibers Incorporating Cinnamaldehyde by Solution Blow Spinning. AB - Cinnamaldehyde, a natural preservative that can non-specifically deactivate foodborne pathogens, was successfully incorporated into fish skin gelatin (FSG) solutions and blow spun into uniform nanofibers. The effects of cinnamaldehyde ratios (5-30%, w/w FSG) on physicochemical properties of fiber-forming emulsions (FFEs) and their nanofibers were investigated. Higher ratios resulted in higher values in particle size and viscosity of FFEs, as well as higher values in diameter of nanofibers. Loss of cinnamaldehyde was observed during solution blow spinning (SBS) process and cinnamaldehyde was mainly located on the surface of resultant nanofibers. Nanofibers all showed antibacterial activity by direct diffusion and vapor release against Escherichia coli O157:H7, Salmonella typhimurium, and Listeria monocytogenes. Inhibition zones increased as cinnamaldehyde ratio increased. Nanofibers showed larger inhibition effects than films prepared by casting method when S. typhimurium was exposed to the released cinnamaldehyde vapor, although films had higher remaining cinnamaldehyde than nanofibers after preparation. Lower temperature was favorable for cinnamaldehyde retention, and nanofibers added with 10% cinnamaldehyde ratio showed the highest retention over eight-weeks of storage. Results suggest that FSG nanofibers can be prepared by SBS as carriers for antimicrobials. PMID- 29470391 TI - Experimental L-Band Airborne SAR for Oil Spill Response at Sea and in Coastal Waters. AB - Satellite synthetic aperture radar (SAR) is frequently used during oil spill response efforts to identify oil slick extent, but suffers from the major disadvantages of potential long latency between when a spill occurs and when a satellite can image the site and an inability to continuously track the spill as it develops. We show using data acquired with the Uninhabited Aerial Vehicle SAR (UAVSAR) instrument how a low noise, high resolution, L-band SAR could be used for oil spill response, with specific examples of tracking slick extent, position and weathering; determining zones of relatively thicker or more emulsified oil within a slick; and identifying oil slicks in coastal areas where look-alikes such as calm waters or biogenic slicks can confound the identification of mineral oil spills. From these key points, the essential features of an airborne SAR system for operational oil spill response are described, and further research needed to determine SAR's capabilities and limitations in quantifying slick thickness is discussed. PMID- 29470392 TI - GJA4/Connexin 37 Mutations Correlate with Secondary Lymphedema Following Surgery in Breast Cancer Patients. AB - Lymphedema is a condition resulting from mutations in various genes essential for lymphatic development and function, which leads to obstruction of the lymphatic system. Secondary lymphedema is a progressive and incurable condition, most often manifesting after surgery for breast cancer. Although its causation appears complex, various lines of evidence indicate that genetic predisposition may play a role. Previous studies show that mutations in connexin 47 are associated with secondary lymphedema. We have tested the hypothesis that connexin 37 gene mutations in humans are associated with secondary lymphedema following breast cancer surgery. A total of 2211 breast cancer patients were screened and tested for reference single nucleotide polymorphisms (SNPs) of the GJA4 gene (gap junction protein alpha 4 gene). The results presented in this paper indicate that two SNPs in the 3' UTR (the three prime untranslated region) of the GJA4 gene are associated with an increased risk of secondary lymphedema in patients undergoing breast cancer treatment. Our results provide evidence of a novel genetic biomarker for assessing the predisposition to secondary lymphedema in human breast cancer patients. Testing for the condition-associated alleles described here could assist and inform treatment and post-operative care plans of breast cancer patients, with potentially positive outcomes for the management of disease progression. PMID- 29470393 TI - DFT Insights into the Role of Relative Positions of Fe and N Dopants on the Structure and Properties of TiO2. AB - The location and nature of the doped elements strongly affect the structural, electronic and optical properties of TiO2. To tailor the band structure and modify the photoelectrochemical properties of TiO2, a pair of dopants is selected. Fe and N atoms are inserted in the TiO2 network at substitutional and interstitial sites with different relative distances. The main objective behind the different locations and sites of the doped elements is to banish the isolated unoccupied states from the forbidden region that normally annihilates the photogenerated carriers. Fe at the Ti site and N at the O site doped in the TiO2 network separated at a distance of 7.805 A provided a suitable configuration of dopant atoms in terms of geometry and band structure. Moreover, the optical properties showed a notable shift to the visible regime. Individual dopants either introduced isolated unoccupied states in the band gap or disturbed the fermi level and structural properties. Furthermore, the other co-doped configurations showed no remarkable band shift, as well as exhibiting a suitable band structure. Resultantly, comparing the band structure and optical properties, it is argued that Fe (at Ti) and N (at O) doped at a distance of 7.805 A would strongly improve the photoelectrochemical properties of TiO2. PMID- 29470394 TI - A Novel Early Warning System Based on a Sediment Microbial Fuel Cell for In Situ and Real Time Hexavalent Chromium Detection in Industrial Wastewater. AB - Hexavalent chromium (Cr(VI)) is a well-known toxic heavy metal in industrial wastewater, but in situ and real time monitoring cannot be achieved by current methods used during industrial wastewater treatment processes. In this study, a Sediment Microbial Fuel Cell (SMFC) was used as a biosensor for in situ real-time monitoring of Cr(VI), which was the organic substrate is oxidized in the anode and Cr(VI) is reduced at the cathode simultaneously. The pH 6.4 and temperature 25 degrees C were optimal conditions for the operation. Under the optimal conditions, linearity (R2 = 0.9935) of the generated voltage was observed in the Cr(VI) concentration range from 0.2 to 0.7 mg/L. The system showed high specificity for Cr(VI), as other co-existing ions such as Cu2+, Zn2+, and Pb2+ did not interfere with Cr(VI) detection. In addition, when the sediment MFC-based biosensor was applied for measuring Cr(VI) in actual wastewater samples, a low deviation (<8%) was obtained, which indicated its potential as a reliable biosensor device. MiSeq sequencing results showed that electrochemically active bacteria (Geobacter and Pseudomonas) were enriched at least two-fold on the biofilm of the anode in the biosensor as compared to the SMFC without Cr(VI). Cyclic voltammetry curves indicated that a pair of oxidation/reduction peaks appeared at -111 mV and 581 mV, respectively. These results demonstrated that the proposed sediment microbial fuel cell-based biosensor can be applied as an early warning device for real time in situ detection of Cr(VI) in industrial wastewaters.

We aimed to determine the sodium and potassium consumption in a semi-urban area in Peru with a cross-sectional study. 24-h urine samples were collected. The outcomes were mean consumption of sodium and potassium, as well as adherence to their consumption recommendation: <2 g/day and >=3.51 g/day, respectively. Bivariate analyses were conducted to identify socio economic and clinical variables associated with the consumption recommendations of 602 participants, complete urine samples were found in 409: mean age of participants was 45.7 (standard deviation (SD): 16.2) years and 56% were women. The mean sodium and potassium consumption was 4.4 (SD: 2.1) and 2.0 (SD: 1.2) g/day. The sodium and potassium recommendation was met by 7.1% and 13.7% of the study sample; none of the participants met both recommendations. People not adherent to the sodium recommendation had higher diastolic (73.1 mmHg vs. 68.2 mmHg, p = 0.015) and systolic (113.1 mmHg vs. 106.3 mmHg, p = 0.047) blood pressure than those who comply with the recommendation. Public health actions ought to be implemented in areas undergoing urbanization to improve sodium and potassium consumption at the population level.

AB - The low temperature coefficient and high linearity of the input-output characteristics are both required for high-performance microelectromechanical systems (MEMS) capacitive accelerometers. In this work, a structural designing of a bulk MEMS capacitive accelerometer is developed for both low temperature coefficient and high linearity. Firstly, the contrary effect of the wide-narrow gaps ratio (WNGR) on the temperature coefficient of the scale factor (TCSF) and linearity error is discussed. Secondly, the ability of an improved structure that can avoid the contrary effect is illustrated. The improved structure is proposed in our previous work for reducing the temperature coefficient of bias (TCB) and TCSF. Within the improved structure, both the TCSF and linearity error decrease with increasing WNGR. Then, the precise designing of the improved structure is developed for achieving lower TCB, TCSF, and linearity error. Finally, the precise structural designing is experimentally verified. PMID- 29470397 TI - The Alphavirus Exit Pathway: What We Know and What We Wish We Knew. AB - Alphaviruses are enveloped positive sense RNA viruses and include serious human pathogens, such as the encephalitic alphaviruses and Chikungunya virus. Alphaviruses are transmitted to humans primarily by mosquito vectors and include species that are classified as emerging pathogens. Alphaviruses assemble highly organized, spherical particles that bud from the plasma membrane. In this review, we discuss what is known about the alphavirus exit pathway during a cellular infection. We describe the viral protein interactions that are critical for virus assembly/budding and the host factors that are involved, and we highlight the recent discovery of cell-to-cell transmission of alphavirus particles via intercellular extensions. Lastly, we discuss outstanding questions in the alphavirus exit pathway that may provide important avenues for future research. PMID- 29470399 TI - A Novel Dicyanoisophorone-Based Ratiometric Fluorescent Probe for Selective Detection of Cysteine and Its Bioimaging Application in Living Cells. AB - A selective and ratiometric turn-on fluorescent probe was designed and synthesized by using a novel dicyanoisophorone-based derivative and acrylate moiety. The probe displayed high stability and good selectivity to cysteine (Cys) over homocysteine (Hcy) and glutathione (GSH). It also exhibited rapid response to Cys within 180 s. Most importantly, the fluorescence intensity ratio at 590 and 525 nm (I590/I525) was linearly dependent on the Cys concentration in the range from 0 to 40 MUM and the detection limit calculated to be 0.48 MUM. This probe was also applied for bioimaging of intracellular Cys in living HeLa cells with low cytotoxicity. PMID- 29470400 TI - RaMP: A Comprehensive Relational Database of Metabolomics Pathways for Pathway Enrichment Analysis of Genes and Metabolites. AB - The value of metabolomics in translational research is undeniable, and metabolomics data are increasingly generated in large cohorts. The functional interpretation of disease-associated metabolites though is difficult, and the biological mechanisms that underlie cell type or disease-specific metabolomics profiles are oftentimes unknown. To help fully exploit metabolomics data and to aid in its interpretation, analysis of metabolomics data with other complementary omics data, including transcriptomics, is helpful. To facilitate such analyses at a pathway level, we have developed RaMP (Relational database of Metabolomics Pathways), which combines biological pathways from the Kyoto Encyclopedia of Genes and Genomes (KEGG), Reactome, WikiPathways, and the Human Metabolome DataBase (HMDB). To the best of our knowledge, an off-the-shelf, public database that maps genes and metabolites to biochemical/disease pathways and can readily be integrated into other existing software is currently lacking. For consistent and comprehensive analysis, RaMP enables batch and complex queries (e.g., list all metabolites involved in glycolysis and lung cancer), can readily be integrated into pathway analysis tools, and supports pathway overrepresentation analysis given a list of genes and/or metabolites of interest. For usability, we have developed a RaMP R package (https://github.com/Mathelab/RaMP-DB), including a user-friendly RShiny web application, that supports basic simple and batch queries, pathway overrepresentation analysis given a list of genes or metabolites of interest, and network visualization of gene-metabolite relationships. The package also includes the raw database file (mysql dump), thereby providing a stand-alone downloadable framework for public use and integration with other tools. In addition, the Python code needed to recreate the database on another system is also publicly available (https://github.com/Mathelab/RaMP-BackEnd). Updates for databases in RaMP will be checked multiple times a year and RaMP will be updated accordingly. PMID- 29470401 TI - The Major Fusarium Species Causing Maize Ear and Kernel Rot and Their Toxigenicity in Chongqing, China. AB - Fusarium verticillioides, F. proliferatum, and F. meridionale were identified as the predominant fungi among 116 Fusarium isolates causing maize ear and kernel rot, a destructive disease in Chongqing areas, China. The toxigenic capability and genotype were determined by molecular amplification and toxin assay. The results showed that the key toxigenic gene FUM1 was detected in 47 F. verticillioides and 19 F. proliferatum isolates. Among these, F. verticillioides and F. proliferatum isolates mainly produced fumonisin B1, ranging from 3.17 to 1566.44, and 97.74 to 11,100.99 ug/g for each gram of dry hyphal weight, with the averages of 263.94 and 3632.88 ug/g, respectively, indicating the F. proliferatum isolates on average produced about an order of magnitude more fumonisins than F. verticillioides did in these areas, in vitro. Only NIV genotype was detected among 16 F. meridionale and three F. asiaticum isolates. Among these, 11 F. meridionale isolates produced NIV, varying from 17.40 to 2597.34 ug/g. ZEA and DON toxins were detected in 11 and 4 F. meridionale isolates, with the toxin production range of 8.35-78.57 and 3.38-33.41 ug/g, respectively. Three F. asiaticum isolates produced almost no mycotoxins, except that one isolate produced a small amount of DON. The findings provide us with insight into the risk of the main pathogenic Fusarium species and a guide for resistance breeding in these areas. PMID- 29470402 TI - Cost-Effectiveness of a Specialized Oral Nutritional Supplementation for Malnourished Older Adult Patients in Spain. AB - Malnutrition has been related to prolonged hospital stays, and to increases in readmission and mortality rates. In the NOURISH (Nutrition effect On Unplanned Readmissions and Survival in Hospitalized patients) study, administering a high protein oral nutritional supplement (ONS) containing beta-hydroxy-beta methylbutyrate (HP-HMB) to hospitalised older adult patients led to a significant improvement in survival compared with a placebo treatment. The aim of this study was to determine whether HP-HMB would be cost-effective in Spain. We performed a cost-effectiveness analysis from the perspective of the Spanish National Health System using time horizons of 90 days, 180 days, 1 year, 2 years, 5 years and lifetime. The difference in cost between patients treated with HP-HMB and placebo was ?332.75. With the 90 days time horizon, the difference in life years gained (LYG) between both groups was 0.0096, resulting in an incremental cost effectiveness ratio (ICER) of ?34,700.62/LYG. With time horizons of 180 days, 1 year, 2 years, 5 years and lifetime, the respective ICERs were ?13,711.68, ?3377.96, ?2253.32, ?1127.34 and ?563.84/LYG. This analysis suggests that administering HP-HMB to older adult patients admitted to Spanish hospitals during hospitalisation and after discharge could be a cost-effective intervention that would improve survival with a reduced marginal cost. PMID- 29470403 TI - Cladodionen, a Cytotoxic Hybrid Polyketide from the Marine-Derived Cladosporium sp. OUCMDZ-1635. AB - A new hybrid polyketide, cladodionen (1), together with a new abscisic acid analogue, cladosacid (2), were isolated from the marine-derived fungus, Cladosporium sp. OUCMDZ-1635. Their structures, including the absolute configurations, were fully elucidated on the basis of spectroscopic analysis, ECD spectra, quantum chemical calculations, and chemical methods. Cladodionen (1) showed cytotoxic activities against MCF-7, HeLa, HCT-116, and HL-60 human cancer cell lines with IC50 values of 18.7, 19.1, 17.9, and 9.1 uM. PMID- 29470405 TI - Gentamicin-Releasing Mesoporous ZnO Structures. AB - Among metal oxides, zinc oxide (ZnO) is one of the most attractive materials thanks to its biocompatible and biodegradable properties along with the existence of various morphologies featuring piezoelectric, semiconducting and photocatalytic activities. All of these structures were successfully prepared and tested for numerous applications, including optoelectronics, sensors and biomedical ones. In the last case, biocompatible ZnO nanomaterials positively influenced cells growth and tissue regeneration as well, promoting wound healing and new bone formation. Despite showing high surface areas, ZnO morphologies generally lack an intrinsic mesoporous structure, strongly limiting the investigation of the corresponding drug loading and release properties. Within this scope, this study focuses on the adsorption and release properties of high surface area, mesoporous ZnO structures using gentamicin sulfate (GS), a well known antibiotic against bacterial infections especially in orthopedics. The particular ZnO morphology was achieved starting from sputtered porous zinc layers, finally converted into ZnO by thermal oxidation. By taking advantage of this mesoporous framework, GS was successfully adsorbed within the ZnO matrix and the kinetic release profile evaluated for up to seven days. The adsorption of GS was successfully demonstrated, with a maximum amount of 263 mg effectively loaded per gram of active material. Then, fast kinetic release was obtained in vitro by simple diffusion mechanism, thus opening further possibilities of smart pore and surface engineering to improve the controlled delivery. PMID- 29470404 TI - Oleanolic Acid Exerts Osteoprotective Effects and Modulates Vitamin D Metabolism. AB - Oleanolic acid (OA) is a triterpenoid with reported bone anti-resorption activities. The present study aimed to characterize its bone protective effects in vivo and to study its effects on vitamin D metabolism, both in vivo and in vitro. OA significantly increased bone mineral density, improved micro architectural properties, reduced urinary Ca excretion, increased 1,25(OH)2D3 and renal CYP27B1 mRNA expression in mature C57BL/6 ovariectomised (OVX) mice. OA also improved bone properties, Ca balance, and exerted modulatory effects on renal CYP27B1 and CYP24A1 expressions in aged normal female Sprague-Dawley rats. In addition, OA significantly increased renal CYP27B1 mRNA and promoter activity, and suppressed CYP24A1 mRNA and protein expressions in human proximal tubule HKC 8 cells. OA exerted bone protective effects in mature OVX mice and aged female rats. This action on bone might be, at least in part, associated with its effects on Ca and vitamin D metabolism. The present findings suggest that OA is a potential drug candidate for the management of postmenopausal osteoporosis. PMID- 29470406 TI - A Spectral Reconstruction Algorithm of Miniature Spectrometer Based on Sparse Optimization and Dictionary Learning. AB - The miniaturization of spectrometer can broaden the application area of spectrometry, which has huge academic and industrial value. Among various miniaturization approaches, filter-based miniaturization is a promising implementation by utilizing broadband filters with distinct transmission functions. Mathematically, filter-based spectral reconstruction can be modeled as solving a system of linear equations. In this paper, we propose an algorithm of spectral reconstruction based on sparse optimization and dictionary learning. To verify the feasibility of the reconstruction algorithm, we design and implement a simple prototype of a filter-based miniature spectrometer. The experimental results demonstrate that sparse optimization is well applicable to spectral reconstruction whether the spectra are directly sparse or not. As for the non directly sparse spectra, their sparsity can be enhanced by dictionary learning. In conclusion, the proposed approach has a bright application prospect in fabricating a practical miniature spectrometer. PMID- 29470407 TI - Toxicity of Pristine and Chemically Functionalized Fullerenes to White Rot Fungus Phanerochaete chrysosporium. AB - Fullerenes are widely produced and applied carbon nanomaterials that require a thorough investigation into their environmental hazards and risks. In this study, we compared the toxicity of pristine fullerene (C60) and carboxylated fullerene (C60-COOH) to white rot fungus Phanerochaete chrysosporium. The influence of fullerene on the weight increase, fibrous structure, ultrastructure, enzyme activity, and decomposition capability of P. chrysosporium was investigated to reflect the potential toxicity of fullerene. C60 did not change the fresh and dry weights of P. chrysosporium but C60-COOH inhibited the weight gain at high concentrations. Both C60 and C60-COOH destroyed the fibrous structure of the mycelia. The ultrastructure of P. chrysosporium was changed by C60-COOH. Pristine C60 did not affect the enzyme activity of the P. chrysosporium culture system while C60-COOH completely blocked the enzyme activity. Consequently, in the liquid culture, P. chrysosporium lost the decomposition activity at high C60-COOH concentrations. The decreased capability in degrading wood was observed for P. chrysosporium exposed to C60-COOH. Our results collectively indicate that chemical functionalization enhanced the toxicity of fullerene to white rot fungi and induced the loss of decomposition activity. The environmental risks of fullerene and its disturbance to the carbon cycle are discussed. PMID- 29470409 TI - Social Image Captioning: Exploring Visual Attention and User Attention. AB - Image captioning with a natural language has been an emerging trend. However, the social image, associated with a set of user-contributed tags, has been rarely investigated for a similar task. The user-contributed tags, which could reflect the user attention, have been neglected in conventional image captioning. Most existing image captioning models cannot be applied directly to social image captioning. In this work, a dual attention model is proposed for social image captioning by combining the visual attention and user attention simultaneously.Visual attention is used to compress a large mount of salient visual information, while user attention is applied to adjust the description of the social images with user-contributed tags. Experiments conducted on the Microsoft (MS) COCO dataset demonstrate the superiority of the proposed method of dual attention. PMID- 29470408 TI - Flexible, Stretchable Sensors for Wearable Health Monitoring: Sensing Mechanisms, Materials, Fabrication Strategies and Features. AB - Wearable health monitoring systems have gained considerable interest in recent years owing to their tremendous promise for personal portable health watching and remote medical practices. The sensors with excellent flexibility and stretchability are crucial components that can provide health monitoring systems with the capability of continuously tracking physiological signals of human body without conspicuous uncomfortableness and invasiveness. The signals acquired by these sensors, such as body motion, heart rate, breath, skin temperature and metabolism parameter, are closely associated with personal health conditions. This review attempts to summarize the recent progress in flexible and stretchable sensors, concerning the detected health indicators, sensing mechanisms, functional materials, fabrication strategies, basic and desired features. The potential challenges and future perspectives of wearable health monitoring system are also briefly discussed. PMID- 29470410 TI - The Evolving Role of Multivitamin/Multimineral Supplement Use among Adults in the Age of Personalized Nutrition. AB - Micronutrient deficiencies occur in segments of the adult population in the United States. Multivitamin/multimineral supplements (MVMS) are widely used by this population, which reduces inadequacies in micronutrient intake, but the potential for exceeding tolerable upper intake levels in others should be considered. There are concerns associated with the excessive intake of certain nutrients, particularly folic acid, and potential untoward consequences. The advent of nutrigenomics and the enhanced ability to directly study the interactions between nutrition and genetic variants and expression will allow for the conduct of more targeted studies with specific endpoints and may ultimately lead to progress in the field of personalized nutrition. The role of MVMS in health maintenance and chronic disease prevention remains controversial. Conducting studies in this area has been hampered by, among other factors, inconsistent definitions of MVMS, ranging from as few as three vitamins to broad spectrum products containing more than two dozen vitamins and minerals. Results from some observational studies and large-scale, randomized, controlled trials suggest that MVMS may reduce the risk of some forms of cancer and, potentially, cardiovascular disease. The ongoing COcoa Supplement and Multivitamin Outcomes Study (COSMOS) is expected to build on this research and provide additional insights into these areas. PMID- 29470412 TI - The Prevailing Catalytic Role of Meteorites in Formamide Prebiotic Processes. AB - Meteorites are consensually considered to be involved in the origin of life on this Planet for several functions and at different levels: (i) as providers of impact energy during their passage through the atmosphere; (ii) as agents of geodynamics, intended both as starters of the Earth's tectonics and as activators of local hydrothermal systems upon their fall; (iii) as sources of organic materials, at varying levels of limited complexity; and (iv) as catalysts. The consensus about the relevance of these functions differs. We focus on the catalytic activities of the various types of meteorites in reactions relevant for prebiotic chemistry. Formamide was selected as the chemical precursor and various sources of energy were analyzed. The results show that all the meteorites and all the different energy sources tested actively afford complex mixtures of biologically-relevant compounds, indicating the robustness of the formamide-based prebiotic chemistry involved. Although in some cases the yields of products are quite small, the diversity of the detected compounds of biochemical significance underlines the prebiotic importance of meteorite-catalyzed condensation of formamide. PMID- 29470411 TI - Stroke-Like Episodes and Cerebellar Syndrome in Phosphomannomutase Deficiency (PMM2-CDG): Evidence for Hypoglycosylation-Driven Channelopathy. AB - Stroke-like episodes (SLE) occur in phosphomannomutase deficiency (PMM2-CDG), and may complicate the course of channelopathies related to Familial Hemiplegic Migraine (FHM) caused by mutations in CACNA1A (encoding CaV2.1 channel). The underlying pathomechanisms are unknown. We analyze clinical variables to detect risk factors for SLE in a series of 43 PMM2-CDG patients. We explore the hypothesis of abnormal CaV2.1 function due to aberrant N-glycosylation as a potential novel pathomechanism of SLE and ataxia in PMM2-CDG by using whole-cell patch-clamp, N-glycosylation blockade and mutagenesis. Nine SLE were identified. Neuroimages showed no signs of stroke. Comparison of characteristics between SLE positive versus negative patients' group showed no differences. Acute and chronic phenotypes of patients with PMM2-CDG or CACNA1A channelopathies show similarities. Hypoglycosylation of both CaV2.1 subunits (alpha1A and alpha2alpha) induced gain-of-function effects on channel gating that mirrored those reported for pathogenic CACNA1A mutations linked to FHM and ataxia. Unoccupied N glycosylation site N283 at alpha1A contributes to a gain-of-function by lessening CaV2.1 inactivation. Hypoglycosylation of the alpha2delta subunit also participates in the gain-of-function effect by promoting voltage-dependent opening of the CaV2.1 channel. CaV2.1 hypoglycosylation may cause ataxia and SLEs in PMM2-CDG patients. Aberrant CaV2.1 N-glycosylation as a novel pathomechanism in PMM2-CDG opens new therapeutic possibilities. PMID- 29470413 TI - Electrical/Mechanical Monitoring of Shape Memory Alloy Reinforcing Fibers Obtained by Pullout Tests in SMA/Cement Composite Materials. AB - Self-healing is an essential property of smart concrete structures. In contrast to other structural metals, shape memory alloys (SMAs) offer two unique effects: shape memory effects, and superelastic effects. Composites composed of SMA wires and conventional cements can overcome the mechanical weaknesses associated with tensile fractures in conventional concretes. Under specialized environments, the material interface between the cementitious component and the SMA materials plays an important role in achieving the enhanced mechanical performance and robustness of the SMA/cement interface. This material interface is traditionally evaluated in terms of mechanical aspects, i.e., strain-stress characteristics. However, the current work attempts to simultaneously characterize the mechanical load displacement relationships synchronized with impedance spectroscopy as a function of displacement. Frequency-dependent impedance spectroscopy is tested as an in situ monitoring tool for structural variations in smart composites composed of non-conducting cementitious materials and conducting metals. The artificial geometry change in the SMA wires is associated with an improved anchoring action that is compatible with the smallest variation in resistance compared with prismatic SMA wires embedded into a cement matrix. The significant increase in resistance is interpreted to be associated with the slip of the SMA fibers following the elastic deformation and the debonding of the SMA fiber/matrix. PMID- 29470414 TI - The Sitting-Height Index of Build, (Body Mass)/(Sitting Height)3, as an Improvement on the Body Mass Index for Children, Adolescents and Young Adults. AB - The body mass index (BMI) is unsatisfactory in being affected by both relative leg length and height, and, for use with children and adolescents, therefore needs to be interpreted in relation to age. The sitting-height index of build (body mass)/(sitting height)3, is largely free of these disadvantages. Furthermore, because that index is independent of relative leg length, the latter can be treated as a separate indicator of nutritional history and health risks. Past studies on white children and adults have shown body mass to be approximately proportional to (sitting height)3. Moreover, multiple regression of (body mass)1/3 on sitting height and leg length, using year-by-year averages, has indicated that leg length is an insignificant predictor of body mass. The present study used data for individuals, namely 2-20 years old males and females, black as well as white. Regression analysis as above again showed leg length to be an insignificant predictor of body mass, but only above the age of about nine years. However, sitting height is still a stronger predictor of body mass than leg length at all ages. The advantages of the sitting-height index of build for use with young people are confirmed. PMID- 29470415 TI - Exclusive Breastfeeding Rate and Complementary Feeding Indicators in China: A National Representative Survey in 2013. AB - Appropriate infant and young child feeding could reduce morbidity and mortality and could improve cognitive development of children. However, nationwide data on exclusive breastfeeding and complementary feeding status in China are scarce. The aim of this study was to assess current exclusive breastfeeding and complementary feeding status in China. A national representative survey (Chinese National Nutrition and Health Survey) of children aged under 6 years was done in 2013. Stratified multistage cluster sampling was used to select study participants. World Health Organization (WHO) infant and young child feeding indicators were firstly used to assess exclusive breastfeeding and complementary feeding practice nationwide. In total, 14,458 children aged under two years (0 to <730 days) were studied from 55 counties in 30 provinces in China. The crude exclusive breastfeeding rate under 6 months was 20.7% (908/4381) and the weighted exclusive breastfeeding rate was 18.6%. The crude prevalence of minimum dietary diversity, minimum meal frequency and minimum acceptable diet were 52.5% (5286/10,071), 69.8% (7027/10,071), and 27.4% (2764/10,071) among children aged 6-23 months, respectively. The weighted rate was 53.7%, 69.1%, and 25.1%, respectively. Residential area, household income and maternal education were positively associated with the three complementary feeding indicators. The exclusive breastfeeding rate under 6 months was low and complementary feeding practice was not optimal in China. Residential area, household income and maternal education might be used to target infants and young children to improve complementary feeding practice. PMID- 29470416 TI - Carbon-Fibre-Reinforced SiC Composite (C/SiSiC) as an Alternative Material for Endoprosthesis: Fabrication, Mechanical and In-Vitro Biological Properties. AB - Particle-induced periprosthetic osteolysis and subsequent aseptic implant loosening are a major cause of compromising the long-term results of total joint replacements. To date, no implant has been able to mirror radically the tribological factors (friction/lubrication/wear) of in vivo tribological pairings. Carbon-Fibre Reinforced SiC-Composites (C/SiSiC), a material primarily developed for brake technology, has the opportunity to fulfil this requirement. Until now, the material itself has not been used in medicine. The aim of this investigation was to test the suitability of C/SiSiC ceramics as a new material for bearing couples in endoprosthetics. After the preparation of the composites flexural strength was determined as well as the Young's-modulus and the coefficient of friction. To investigate in vitro biological properties, MG 63 and primary human osteoblasts were cultured on C/SiSiC composites. To review the proliferation, the cytotoxicity standardized tests were used. The cell morphology was observed by light microscopy, ESEM, confocal and 3D-laserscanning microscopy. C/SiSiC possesses a high resistance to wear. Cells exhibited no significant alterations in morphology. Vitality was not impaired by contact with the ceramic composite. There was no higher cytotoxicity to observe. Regarding these results, C/SiSiC ceramics seem to be biologically and mechanically appropriate for orthopaedic applications. PMID- 29470417 TI - Ultrarapid Multimode Microwave Synthesis of Nano/Submicron beta-SiC. AB - This paper presents the design, development and realization of a fast and novel process for the synthesis of 3C silicon carbide (beta-SiC) nanorods and submicron powder. Using SiO2 (or Si) and activated carbon (AC), this process allows beta SiC to be synthesized with almost 100% purity in timeframes of seconds or minutes using multimode microwave rotary tube reactors under open-air conditions. The synthesis temperature used was 1460 +/- 50 degrees C for Si + AC and 1660 +/- 50 degrees C for SiO2 + AC. The shortest beta-SiC synthesis time achieved was about 20 s for Si + AC and 100 s for SiO2 + AC. This novel synthesis method allows for scaled-up flow processes in the rapid industrial-scale production of beta-SiC, having advantages of time/energy saving and carbon dioxide emission reduction over comparable modern processes. PMID- 29470418 TI - Tetrodotoxin, a Candidate Drug for Nav1.1-Induced Mechanical Pain? AB - Tetrodotoxin (TTX), the mode of action of which has been known since the 1960s, is widely used in pharmacology as a specific inhibitor of voltage-gated sodium channels (Nav channels). This toxin has contributed to the characterization of the allosteric model of the Nav channel, and to discriminating TTX-sensitive and TTX-resistant subtypes. In addition to its role as a pharmacological tool, TTX is now considered a therapeutic molecule, and its development should lead to its use in certain pathologies involving Nav channels, particularly in the field of pain. Specifically, the blockade of Nav channels expressed in nociceptive fibres is one strategy for alleviating pain and its deleterious consequences on health. Recent work has identified, in addition to the Nav1.7, 1.8 and 1.9 channels, the Nav1.1 subtype on dorsal root ganglion (DRG) neurons as a crucial player in mechanical and non-thermal pain. The sensitivity of Nav1.1 to TTX could be exploited at the therapeutic level, especially in chronic pain conditions. PMID- 29470419 TI - Nanotherapy and Reactive Oxygen Species (ROS) in Cancer: A Novel Perspective. AB - The incidence of numerous types of cancer has been increasing over recent years, representing the second-most frequent cause of death after cardiovascular diseases. Even though, the number of effective anticancer drugs is increasing as well, a large number of patients suffer from severe side effects (e.g., cardiomyopathies) caused by these drugs. This adversely affects the patients' well-being and quality of life. On the molecular level, tumor cells that survive treatment modalities can become chemotherapy-resistant. In addition, adverse impacts on normal (healthy, stromal) cells occur concomitantly. Strategies that minimize these negative impacts on normal cells and which at the same time target tumor cells efficiently are needed. Recent studies suggest that redox-based combinational nanotherapies may represent one option in this direction. Here, we discuss recent advances in the application of nanoparticles, alone or in combination with other drugs, as a promising anticancer tool. Such novel strategies could well minimize harmful side effects and improve patients' health prognoses. PMID- 29470420 TI - Enhanced Antitumor Effects of Epidermal Growth Factor Receptor Targetable Cetuximab-Conjugated Polymeric Micelles for Photodynamic Therapy. AB - Nanocarrier-based delivery systems are promising strategies for enhanced therapeutic efficacy and safety of toxic drugs. Photodynamic therapy (PDT)-a light-triggered chemical reaction that generates localized tissue damage for disease treatments-usually has side effects, and thus patients receiving photosensitizers should be kept away from direct light to avoid skin phototoxicity. In this study, a clinically therapeutic antibody cetuximab (C225) was conjugated to the surface of methoxy poly(ethylene glycol)-b-poly(lactide) (mPEG-b-PLA) micelles via thiol-maleimide coupling to allow tumor-targetable chlorin e6 (Ce6) delivery. Our results demonstrate that more C225-conjugated Ce6 loaded polymeric micelles (C225-Ce6/PM) were selectively taken up than Ce6/PM or IgG conjugated Ce6/PM by epidermal growth factor receptor (EGFR)-overexpressing A431 cells observed by confocal laser scanning microscopy (CLSM), thereby decreasing the IC50 value of Ce6-mediated PDT from 0.42 to 0.173 MUM. No significant differences were observed in cellular uptake study or IC50 value between C225-Ce6/PM and Ce6/PM groups in lower EGFR expression HT-29 cells. For antitumor study, the tumor volumes in the C225-Ce6/PM-PDT group (percentage of tumor growth inhibition, TGI% = 84.8) were significantly smaller than those in the Ce6-PDT (TGI% = 38.4) and Ce6/PM-PDT groups (TGI% = 53.3) (p < 0.05) at day 21 through reduced cell proliferation in A431 xenografted mice. These results indicated that active EGFR targeting of photosensitizer-loaded micelles provides a possible way to resolve the dose-limiting toxicity of conventional photosensitizers and represents a potential delivery system for PDT in a clinical setting. PMID- 29470421 TI - Phytochemicals in Human Milk and Their Potential Antioxidative Protection. AB - Diets contain secondary plant metabolites commonly referred to as phytochemicals. Many of them are believed to impact human health through various mechanisms, including protection against oxidative stress and inflammation, and decreased risks of developing chronic diseases. For mothers and other people, phytochemical intake occurs through the consumption of foods such as fruits, vegetables, and grains. Research has shown that some these phytochemicals are present in the mother's milk and can contribute to its oxidative stability. For infants, human milk (HM) represents the primary and preferred source of nutrition because it is a complete food. Studies have reported that the benefit provided by HM goes beyond basic nutrition. It can, for example, reduce oxidative stress in infants, thereby reducing the risk of lung and intestinal diseases in infants. This paper summarizes the phytochemicals present in HM and their potential contribution to infant health. PMID- 29470422 TI - Fragment-Based Discovery of Inhibitors of the Bacterial DnaG-SSB Interaction. AB - In bacteria, the DnaG primase is responsible for synthesis of short RNA primers used to initiate chain extension by replicative DNA polymerase(s) during chromosomal replication. Among the proteins with which Escherichia coli DnaG interacts is the single-stranded DNA-binding protein, SSB. The C-terminal hexapeptide motif of SSB (DDDIPF; SSB-Ct) is highly conserved and is known to engage in essential interactions with many proteins in nucleic acid metabolism, including primase. Here, fragment-based screening by saturation-transfer difference nuclear magnetic resonance (STD-NMR) and surface plasmon resonance assays identified inhibitors of the primase/SSB-Ct interaction. Hits were shown to bind to the SSB-Ct-binding site using 15N-1H HSQC spectra. STD-NMR was used to demonstrate binding of one hit to other SSB-Ct binding partners, confirming the possibility of simultaneous inhibition of multiple protein/SSB interactions. The fragment molecules represent promising scaffolds on which to build to discover new antibacterial compounds. PMID- 29470423 TI - 3,5,6,7,8,3',4'-Heptamethoxyflavone, a Citrus Flavonoid, Inhibits Collagenase Activity and Induces Type I Procollagen Synthesis in HDFn Cells. AB - Citrus fruits contain various types of flavonoids with powerful anti-aging and photoprotective effects on the skin, and have thus been attracting attention as potential, efficacious skincare agents. Here, we aimed to investigate the chemical composition of Citrus unshiu and its protective effects on photoaging. We isolated and identified a bioactive compound, 3,5,6,7,8,3',4' heptamethoxyflavone (HMF), from C. unshiu peels using ethanol extraction and hexane fractionation. HMF inhibited collagenase activity and increased type I procollagen content in UV-induced human dermal fibroblast neonatal (HDFn) cells. HMF also suppressed the expression of matrix metalloproteinases 1 (MMP-1) and induced the expression of type I procollagen protein in UV-induced HDFn cells. Additionally, HMF inhibited ultraviolet B (UVB)-induced phosphorylation of the mitogen-activated protein kinases (MAPK) cascade signaling components-ERK, JNK, and c-Jun-which are involved in the induction of MMP-1 expression. Furthermore, HMF affected the TGF-beta/Smad signaling pathway, which is involved in the regulation of type I procollagen expression. In particular, HMF induced Smad3 protein expression and suppressed Smad7 protein expression in UV-induced HDFn cells in a dose-dependent manner. These findings suggest a role for Citrusunshiu in the preparation of skincare products in future.

AB - The perspectives of at-risk adolescent clients can play an important role in informing treatment services. The current study examines qualitative interview data from 15 young women with histories of maltreatment. Using a semi-structured qualitative interview approach, we asked the women to think retrospectively about their treatment experiences as adolescent girls. Results highlight the need for providing adolescent girls with reliable and practical information about risky sexual behavior and drug use from relatable and trustworthy helping professionals. We discuss strategies for developing and maintaining trust and delivering specific content.

AB - To assess the health conditions of tree trunks, it is necessary to estimate the layers and anomalies of their internal structure. The main objective of this paper is to investigate the internal part of tree trunks considering their irregular contour. In this respect, we used ground penetrating radar (GPR) for non-invasive detection of defects and deteriorations in living trees trunks. The Hilbert transform algorithm and the reflection amplitudes were used to estimate the relative dielectric constant. The point cloud data technique was applied as well to extract the irregular contours of trunks. The feasibility and accuracy of the methods were examined through numerical simulations, laboratory and field measurements. The results demonstrated that the applied methodology allowed for accurate characterizations of the internal inhomogeneity. Furthermore, the point cloud technique resolved the trunk well by providing high-precision coordinate information. This study also demonstrated that cross-section tomography provided images with high resolution and accuracy. These integrated techniques thus proved to be promising for observing tree trunks and other cylindrical objects. The applied approaches offer a great promise for future 3D reconstruction of tomographic images with radar wave. PMID- 29470426 TI - Surface Plasmon Resonance and Bending Loss-Based U-Shaped Plastic Optical Fiber Biosensors. AB - Escherichia coli (E. coli) is a large and diverse bacteria group that inhabits the intestinal tract of many mammals. Most E. coli strains are harmless, however some of them are pathogenic, meaning they can make one sick if ingested. By being in the feces of animals and humans, its presence in water and food is used as indicator of fecal contamination. The main method for this microorganism detection is the bacterial culture medium that is time-consuming and requires a laboratory with specialized personnel. Other sophisticated methods are still not fast enough because they require sending samples to a laboratory and with a high cost of analysis. In this paper, a gold-coated U-shaped plastic optical fiber (POF) biosensor for E. coli bacteria detection is presented. The biosensor works by intensity modulation principle excited by monochromatic light where the power absorption is imposed by predominant effect of either bending loss or surface plasmon resonance (SPR), depending on the gold thickness. Bacterial selectivity is obtained by antibody immobilization on the fiber surface. The biosensor showed a detection limit of 1.5 * 103 colony-forming units (CFU)/mL, demonstrating that the technology can be a portable, fast response and low-cost alternative to conventional methodologies for quality analysis of water and food.

AB - Allogeneic hematopoietic stem cell transplantation (HSCT) represents a curative treatment for many patients with hematological malignant or non-malignant disorders. Evaluation of potential donors for HSCT includes a rigorous assessment of the human leukocyte antigens (HLA) match status of family members, and the identification of suitable unrelated donors. Genes encoding transplantation antigens are placed both within and outside the major histocompatibility complex (MHC). The human MHC is located on the short arm of chromosome 6 and contains a series of genes encoding two distinct types of highly polymorphic cell surface glycoproteins. Donors for HSCT are routinely selected based on the level of matching for HLA-A, -B, -C, -DRB1, and -DQB1 loci. However, disease relapse, graft-versus-host-disease, and infection remain significant risk factors of morbidity and mortality. In the same breath, in high-risk patients, graft-versus leukemia effects inherent in HLA mismatching play a substantial immunological role to limit the recurrence of post-transplant disease. The definition of a suitable donor is ever changing, shaped not only by current typing technology, but also by the specific transplant procedure. Indeed, a more complete understanding of permissible HLA mismatches and the role of Killer Immunoglobulin like receptors' genes increases the availability of HLA-haploidentical and unrelated donors. PMID- 29470428 TI - Determining Forest Duff Water Content Using a Low-Cost Standing Wave Ratio Sensor. AB - Forest duff (fermentation and humus) water content is an important parameter for fire risk prediction and water resource management. However, accurate determination of forest duff water content is difficult due to its loose structure. This study evaluates the feasibility of a standing wave ratio (SWR) sensor to accurately determine the forest duff water content. The performance of this sensor was tested on fermentation and humus with eight different compaction levels. Meanwhile, a commercialized time domain reflectometry (TDR) was employed for comparison. Calibration results showed that there were strong linear relationships between the volumetric water content (thetaV) and the SWR sensor readings (VSWR) at different compaction classes for both fermentation and humus samples. The sensor readings of both SWR and TDR underestimated the forest duff water content at low compacted levels, proving that the compaction of forest duff could significantly affect the measurement accuracy of both sensors. Experimental data also showed that the accuracy of the SWR sensor was higher than that of TDR according to the root mean square error (RMSE). Furthermore, low cost is another important advantage of the SWR sensor in comparison with TDR. This low-cost SWR sensor performs well in loose materials and is feasible for evaluating the water content of forest duff. In addition, the results indicate that decomposition of the forest duff should be taken into account for continuous and long-term water content measurement. PMID- 29470429 TI - Belowground Interactions Impact the Soil Bacterial Community, Soil Fertility, and Crop Yield in Maize/Peanut Intercropping Systems. AB - Intercropping has been widely used to control disease and improve yield in agriculture. In this study, maize and peanut were used for non-separation intercropping (NS), semi-separation intercropping (SS) using a nylon net, and complete separation intercropping (CS) using a plastic sheet. In field experiments, two-year land equivalent ratios (LERs) showed yield advantages due to belowground interactions when using NS and SS patterns as compared to monoculture. In contrast, intercropping without belowground interactions (CS) showed a yield disadvantage. Meanwhile, in pot experiments, belowground interactions (found in NS and SS) improved levels of soil-available nutrients (nitrogen (N) and phosphorus (P)) and enzymes (urease and acid phosphomonoesterase) as compared to intercropping without belowground interactions (CS). Soil bacterial community assay showed that soil bacterial communities in the NS and SS crops clustered together and were considerably different from the CS crops. The diversity of bacterial communities was significantly improved in soils with NS and SS. The abundance of beneficial bacteria, which have the functions of P-solubilization, pathogen suppression, and N-cycling, was improved in maize and peanut soils due to belowground interactions through intercropping. Among these bacteria, numbers of Bacillus, Brevibacillusbrevis, and Paenibacillus were mainly increased in the maize rhizosphere. Burkholderia, Pseudomonas, and Rhizobium were mainly increased in the peanut rhizosphere. In conclusion, using maize and peanut intercropping, belowground interactions increased the numbers of beneficial bacteria in the soil and improved the diversity of the bacterial community, which was conducive to improving soil nutrient (N and P) supply capacity and soil microecosystem stability. PMID- 29470430 TI - Metabolic Responses in Endothelial Cells Following Exposure to Ketone Bodies. AB - The ketogenic diet (KD) is a high-fat, low-carbohydrate diet based on the induction of the synthesis of ketone bodies (KB). Despite its widespread use, the systemic impact of KD is not completely understood. The purpose of this study was to evaluate the effects of physiological levels of KB on HMEC-1 endothelial cells. To this aim, DNA oxidative damage and the activation of Nrf2, a known transcriptional factor involved in cell responses to oxidative stress, were assessed. The exposure of cells to KB exerted a moderate genotoxic effect, measured by a significant increase in DNA oxidative damage. However, cells pre treated with KB for 48 h and subjected to a secondary oxidative insult (H2O2), significantly decreased DNA damage compared to control oxidized cells. This protection occurred by the activation of Nrf2 pathway. In KB-treated cells, we found increased levels of Nrf2 in nuclear extracts and higher gene expression of HO-1, a target gene of Nrf2, compared to control cells. These results suggest that KB, by inducing moderate oxidative stress, activate the transcription factor Nrf2, which induces the transcription of target genes involved in the cellular antioxidant defense system. PMID- 29470432 TI - Optical Method for Estimating the Chlorophyll Contents in Plant Leaves. AB - This work introduces a new vision-based approach for estimating chlorophyll contents in a plant leaf using reflectance and transmittance as base parameters. Images of the top and underside of the leaf are captured. To estimate the base parameters (reflectance/transmittance), a novel optical arrangement is proposed. The chlorophyll content is then estimated by using linear regression where the inputs are the reflectance and transmittance of the leaf. Performance of the proposed method for chlorophyll content estimation was compared with a spectrophotometer and a Soil Plant Analysis Development (SPAD) meter. Chlorophyll content estimation was realized for Lactuca sativa L., Azadirachta indica, Canavalia ensiforme, and Lycopersicon esculentum. Experimental results showed that-in terms of accuracy and processing speed-the proposed algorithm outperformed many of the previous vision-based approach methods that have used SPAD as a reference device. On the other hand, the accuracy reached is 91% for crops such as Azadirachta indica, where the chlorophyll value was obtained using the spectrophotometer. Additionally, it was possible to achieve an estimation of the chlorophyll content in the leaf every 200 ms with a low-cost camera and a simple optical arrangement. This non-destructive method increased accuracy in the chlorophyll content estimation by using an optical arrangement that yielded both the reflectance and transmittance information, while the required hardware is cheap. PMID- 29470431 TI - Articular Cartilage Aging-Potential Regenerative Capacities of Cell Manipulation and Stem Cell Therapy. AB - Changes in articular cartilage during the aging process are a stage of natural changes in the human body. Old age is the major risk factor for osteoarthritis but the disease does not have to be an inevitable consequence of aging. Chondrocytes are particularly prone to developing age-related changes. Changes in articular cartilage that take place in the course of aging include the acquisition of the senescence-associated secretory phenotype by chondrocytes, a decrease in the sensitivity of chondrocytes to growth factors, a destructive effect of chronic production of reactive oxygen species and the accumulation of the glycation end products. All of these factors affect the mechanical properties of articular cartilage. A better understanding of the underlying mechanisms in the process of articular cartilage aging may help to create new therapies aimed at slowing or inhibiting age-related modifications of articular cartilage. This paper presents the causes and consequences of cellular aging of chondrocytes and the biological therapeutic outlook for the regeneration of age-related changes of articular cartilage. PMID- 29470433 TI - Monitoring Heavy Metal Contents with Sphagnum Junghuhnianum Moss Bags in Relation to Traffic Volume in Wuxi, China. AB - Despite its small size, a moss bag can reveal the different temporal and spatial deposition patterns of pollutants at a particular site; therefore, researchers can use moss bags to determine pollution sources and to put forward strategies for pollution control. Although the use of moss bags to monitor atmospheric pollution has been widely reported in Europe, there are few such empirical studies in China. Thus, in this study, bags containing the moss Sphagnum junghuhnianum were used to assess the concentrations of heavy metals (chromium (Cr), copper (Cu), lead (Pb), vanadium (V), and zinc (Zn)) at five sampling sites (four roads and a forest park) during the summer and winter of 2012. According to the relative accumulation factor (RAF) and contamination factor (CF) results, pollution in winter was heavier than that in summer, and Cr was found to be the most contaminating, having the highest mean CF. There was a significant positive correlation (p < 0.05) between traffic volume and concentration for three heavy metals (Cr, Cu, and V) in winter, whereas a significant positive correlation (p < 0.05) was observed between traffic volume and concentrations for four heavy metal elements (Cr, Pb, V, and Zn) in summer, indicating a close relationship between heavy metal contents and traffic volume. Although there was substantial variation in the concentrations of the five heavy metals in the moss bags, significant correlations between heavy metals suggested that the contaminants originated from a common source, namely vehicle emissions. The results demonstrated that the four roads were subject to different degrees of pollution depending on the volume of traffic using each road. Therefore, the results of this study suggest that traffic volume is a major reason for heavy metal pollution. PMID- 29470434 TI - Pharmacokinetics and Scintigraphic Imaging of the Hypoxia-Imaging Agent [123I]IAZA in Healthy Adults Following Exercise-Based Cardiac Stress ?. AB - The objective of this work is to evaluate the potential effect of cardiac stress exercise on the accumulation of [123I]IAZA, a radiopharmaceutical used to image focal tissue hypoxia, in otherwise normal myocardium in healthy volunteers, and to determine the impact of exercise on [123I]IAZA pharmacokinetics. The underlying goal is to establish a rational basis and a baseline for studies of focal myocardial hypoxia in cardiac patients using [123I]IAZA. Three healthy male volunteers ran the 'Bruce' treadmill protocol, a clinically-accepted protocol designed to expose myocardial ischemia in patients. The 'Bruce' criterion heart rate is 85% of [220-age]. Approximately one minute before reaching this level, [123I]IAZA (5.0 mCi/0.85 mg) was administered as a slow (1-3 min) single intravenous (i.v.) injection via an indwelling venous catheter. The volunteer continued running for an additional 1 min before being transferred to a gamma camera. Serum samples were collected from the arm contralateral to the administration site at pre-determined intervals from 1 min to 45 h post injection and were analyzed by radio HPLC. Pharmacokinetic (PK) parameters were derived for [123I]IAZA and total radioactivity (total[123I]) using compartmental and noncompartmental analyses. Whole-body planar scintigraphic images were acquired from 0.75 to 24 h after dosing. PK data and scintigraphic images were compared to previously published [123I]IAZA data from healthy volunteers rest. Following exercise stress, both [123I]IAZA and total[123I] exhibited bi-exponential decline profiles, with rapid distribution phases [half-lives (t1/2alpha) of 1.2 and 1.4 min, respectively], followed by slower elimination phases [t1/2beta of 195 and 290 min, respectively]. Total body clearance (CLTB) and the steady state volume of distribution (Vss) were 0.647 L/kg and 185 mL/min, respectively, for [123I]IAZA and 0.785 L/kg and 135 mL/min, respectively, for total[123I]. The t1/2beta, CLTB and Vss values were comparable to those reported previously for rested volunteers. The t1/2alpha was approximately 4-fold shorter for [123I]IAZA and approximately 3-fold shorter for total[123I] under exercise relative to rested subjects. The heart region was visualized in early whole body scintigraphic images, but later images showed no accumulated radioactivity in this region, and no differences from images reported for rested volunteers were apparent. Minimal uptake of radiotracer in myocardium and skeletal muscle was consistent with uptake in non-stressed myocardium. Whole-body scintigrams for [123I]IAZA in exercise-stressed healthy volunteers were indistinguishable from images of non-exercised volunteers. There was no evidence of hypoxia-dependent binding in exercised but otherwise healthy myocardium, supporting the conclusion that exercise stress at Bruce protocol intensity does not induce measurable myocardial hypoxia. Effects of exercise on PK parameters were minimal; specifically, the t1/2alpha was shortened, reflecting increased cardiac output associated with exercise. It is concluded that because [123I]IAZA was not metabolically bound in exercise-stressed myocardium, a stress test will not create elevated myocardial background that would mask regions of myocardial perfusion deficiency. [123I]IAZA would therefore be suitable for the detection of viable, hypoxic myocardium in patients undergoing stress-test-based diagnosis. PMID- 29470435 TI - Creative Arts Interventions for Stress Management and Prevention-A Systematic Review. AB - Stress is one of the world's largest health problems, leading to exhaustion, burnout, anxiety, a weak immune system, or even organ damage. In Germany, stress induced work absenteeism costs about 20 billion Euros per year. Therefore, it is not surprising that the Central Federal Association of the public Health Insurance Funds in Germany ascribes particular importance to stress prevention and stress management as well as health enhancing measures. Building on current integrative and embodied stress theories, Creative Arts Therapies (CATs) or arts interventions are an innovative way to prevent stress and improve stress management. CATs encompass art, music, dance/movement, and drama therapy as their four major modalities. In order to obtain an overview of CATs and arts interventions' efficacy in the context of stress reduction and management, we conducted a systematic review with a search in the following data bases: Academic Search Complete, ERIC, Medline, Psyndex, PsycINFO and SocINDEX. Studies were included employing the PICOS principle and rated according to their evidence level. We included 37 studies, 73% of which were randomized controlled trials. 81.1% of the included studies reported a significant reduction of stress in the participants due to interventions of one of the four arts modalities. PMID- 29470436 TI - Neurobiology of Propofol Addiction and Supportive Evidence: What Is the New Development? AB - Propofol is a short-acting intravenous anesthetic agent suitable for induction and maintenance of general anesthesia as well as for procedural and intensive care unit sedation. As such it has become an unparalleled anesthetic agent of choice in many institutional and office practices. However, in addition to its idealistic properties as an anesthetic agent, there is accumulating evidence suggesting its potential for abuse. Clinical and experimental evidence has revealed that not only does propofol have the potential to be abused, but also that addiction to propofol shows a high mortality rate. Based on this evidence, different researchers have shown interest in determining the probability of propofol to be an addictive agent by comparing it with other drugs of abuse and depicting a functional similitude that involves the mesocorticolimbic pathway of addiction. In light of this, the Drug Enforcement Agency and the American Society of Anesthesiologists have put forth certain safety recommendations for the use of propofol. Despite this, the abuse potential of propofol has been challenged at different levels and therefore the preeminent focus will be to further validate the linkage from medicinal and occasional use of propofol to its addiction, as well as to explore the cellular and molecular targets involved in establishing this linkage, so as to curb the harm arising out of it. This review incorporates the clinical and biomolecular evidence supporting the abuse potential of propofol and brings forth the promising targets and the foreseeable mechanism causing the propofol addiction phenotypes, which can be called upon for future developments in this field. PMID- 29470437 TI - Neurophysiological Assessment of Abnormalities of the Neuromuscular Junction in Children. AB - The function of the neuromuscular junction in children is amenable to electrophysiological testing. Of the two tests available, repetitive nerve stimulation is uncomfortable and has a reduced sensitivity compared with single fibre methodology. The latter is the method of choice, recording the variability in neuromuscular transmission as a value called jitter. It can be performed by voluntary activation of the muscle being examined, which is not suitable in children, or by stimulation techniques. A modification of these techniques, called Stimulated Potential Analysis with Concentric needle Electrodes (SPACE), is well tolerated and can be performed while the child is awake. It has a high sensitivity (84%) for the diagnosis of neuromuscular transmission disorders, the majority of which are myasthenic syndromes, and a moderate specificity (70%). The latter can be improved by the exclusion of neurogenic causes and the determination of the degree of jitter abnormality. Minor jitter abnormalities, under 115% of the upper limit of normal, are usually caused by myopathies with an associated neuromuscular transmission disorder, whereas levels higher than this value are usually associated with one of the myasthenic conditions. PMID- 29470439 TI - Study of Hexane Adsorption on Activated Carbons with Differences in Their Surface Chemistry. AB - The study of aliphatic compounds adsorption on activated carbon can be carried out from the energetic change involved in the interaction; the energy values can be determined from isotherms or by the immersion enthalpy. Vapor phase adsorption isotherms of hexane at 263 K on five activated carbons with different content of oxygenated groups and the immersion enthalpy of the activated carbons in hexane and water were determined in order to characterize the interactions in the solid liquid system, and for calculating the hydrophobic factor of the activated carbons. The micropore volume and characteristic energy from adsorption isotherms of hexane, the BET (Brunauer-Emmett-Teller) surface area from the adsorption isotherms of N2, and the area accessible to the hexane from the immersion enthalpy were calculated. The activated carbon with the lowest content of oxygenated groups (0.30 umolg-1) and the highest surface area (996 m2g-1) had the highest hexane adsorption value: 0.27 mmol g-1; the values for Eo were between 5650 and 6920 Jmol-1 and for DeltaHim were between -66.1 and -16.4 Jg-1. These determinations allow us to correlate energetic parameters with the surface area and the chemical modifications that were made to the solids, where the surface hydrophobic character of the activated carbon favors the interaction. PMID- 29470438 TI - Altered Expression of Ganglioside Metabolizing Enzymes Results in GM3 Ganglioside Accumulation in Cerebellar Cells of a Mouse Model of Juvenile Neuronal Ceroid Lipofuscinosis. AB - Juvenile neuronal ceroid lipofuscinosis (JNCL) is caused by mutations in the CLN3 gene. Most JNCL patients exhibit a 1.02 kb genomic deletion removing exons 7 and 8 of this gene, which results in a truncated CLN3 protein carrying an aberrant C terminus. A genetically accurate mouse model (Cln3Deltaex7/8 mice) for this deletion has been generated. Using cerebellar precursor cell lines generated from wildtype and Cln3Deltaex7/8 mice, we have here analyzed the consequences of the CLN3 deletion on levels of cellular gangliosides, particularly GM3, GM2, GM1a and GD1a. The levels of GM1a and GD1a were found to be significantly reduced by both biochemical and cytochemical methods. However, quantitative high-performance liquid chromatography analysis revealed a highly significant increase in GM3, suggesting a metabolic blockade in the conversion of GM3 to more complex gangliosides. Quantitative real-time PCR analysis revealed a significant reduction in the transcripts of the interconverting enzymes, especially of beta 1,4-N-acetyl-galactosaminyl transferase 1 (GM2 synthase), which is the enzyme converting GM3 to GM2. Thus, our data suggest that the complex a-series gangliosides are reduced in Cln3Deltaex7/8 mouse cerebellar precursor cells due to impaired transcription of the genes responsible for their synthesis. PMID- 29470440 TI - Membranes: A Variety of Energy Landscapes for Many Transfer Opportunities. AB - A membrane can be represented by an energy landscape that solutes or colloids must cross. A model accounting for the momentum and the mass balances in the membrane energy landscape establishes a new way of writing for the Darcy law. The counter-pressure in the Darcy law is no longer written as the result of an osmotic pressure difference but rather as a function of colloid-membrane interactions. The ability of the model to describe the physics of the filtration is discussed in detail. This model is solved in a simplified energy landscape to derive analytical relationships that describe the selectivity and the counter pressure from ab initio operating conditions. The model shows that the stiffness of the energy landscape has an impact on the process efficiency: a gradual increase in interactions (such as with hourglass pore shape) can reduce the separation energetic cost. It allows the introduction of a new paradigm to increase membrane efficiency: the accumulation that is inherent to the separation must be distributed across the membrane. Asymmetric interactions thus lead to direction-dependent transfer properties and the membrane exhibits diode behavior. These new transfer opportunities are discussed. PMID- 29470441 TI - Effect of Silver-Emitting Filler on Antimicrobial and Mechanical Properties of Soft Denture Lining Material. AB - Colonization of silicone-based soft lining materials by pathogenic yeast-type fungi is a common problem associated with the use of dentures. In this study, silver sodium hydrogen zirconium phosphate (SSHZP) was introduced into polydimethylsiloxane-based material as an antimicrobial filler at concentrations of 0.25, 0.5, 1, 2, 4, 6, 8, 10, 12, and 14% (w/w). The in vitro antimicrobial efficacy was investigated. Candida albicans was used as a characteristic representative of pathogenic oral microflora. Staphylococcus aureus and Escherichia coli were used as the typical Gram-positive and Gram-negative bacterial strains, respectively. The effect of filler addition on the Shore A hardness, tensile strength, tensile bond strength, sorption, and solubility was investigated. An increase in the filler concentration resulted in an increase in hardness, sorption, and solubility, and for the highest concentration, a decrease in bond strength. The favorable combination of antimicrobial efficacy with other properties was achieved at filler concentrations ranging from 2% to 10%. These composites exhibited mechanical properties similar to the material without the antimicrobial filler and enhanced in vitro antimicrobial efficiency. PMID- 29470442 TI - Phycocyanin Protects Against UVB-induced Apoptosis Through the PKC alpha/betaII Nrf-2/HO-1 Dependent Pathway in Human Primary Skin Cells. AB - Phycocyanin (Pc) is one of the active pigment constituents of Spirulina microalgae. It has been used for its potent antioxidant and anti-inflammatory properties. However, the protective effects of Pc against ultraviolet-B (UVB) induced primary skin cells damage are still undefined. In the present study, we investigated whether Pc prevented UVB-induced apoptotic cell death in human dermal fibroblasts (HDF) and human epidermal keratinocytes (HEK). Pc induced the transcription of heme oxygenase-1 (HO-1). Furthermore, Pc treatments resulted in a marked increase in nuclear factor erythroid-derived 2 (NF-E2)-like 2 (Nrf-2) nuclear translocation. Also, Pc protected UVB induced apoptosis and reduced the p53 and Bax levels, as well as caspase-3 activation. Pc treatment showed a significantly enhanced effect on the phosphorylation of protein kinase C (PKC) alpha/beta II, but not that of p38 mitogen-activated protein kinase (MAPK) or Akt. Induction of HO-1 induced by Pc was suppressed by Go6976, a selective inhibitor of PKC alpha/beta II. In addition, knockdown of HO-1 by small interfering (siRNA) caused a significant increase in poly (ADP-ribose) polymerase 1 (PARP-1) cleavage and caspase-3 activation after Pc pretreatment. Taken together, our results demonstrate that Pc-induced expression of HO-1 is mediated by the PKC alpha/beta II-Nrf-2/HO-1 pathway, and inhibits UVB-induced apoptotic cell death in primary skin cells. PMID- 29470443 TI - Structure-Antiplatelet Activity Relationships of Novel Ruthenium (II) Complexes: Investigation of Its Molecular Targets. AB - The regulation of platelet function by pharmacological agents that modulate platelet signaling has proven to be a positive approach to the prevention of thrombosis. Ruthenium complexes are fascinating for the development of new drugs, as they possess numerous chemical and biological properties. The present study aims to evaluate the structure-activity relationship (SAR) of newly synthesized ruthenium (II) complexes, TQ-1, TQ-2 and TQ-3 in agonists-induced washed human platelets. Silica gel column chromatography, aggregometry, immunoblotting, NMR, and X-ray analyses were performed in this study. Of the three tested compounds, TQ-3 showed a concentration (1-5 MUM) dependent inhibitory effect on platelet aggregation induced by collagen (1 MUg/mL) and thrombin (0.01 U/mL) in washed human platelets; however, TQ-1 and TQ-2 had no response even at 250 MUM of collagen and thrombin-induced aggregation. TQ-3 was effective with inhibiting collagen-induced ATP release, calcium mobilization ([Ca2+]i) and P-selectin expression without cytotoxicity. Moreover, TQ-3 significantly abolished collagen induced Lyn-Fyn-Syk, Akt-JNK and p38 mitogen-activated protein kinases (p38 MAPKs) phosphorylation. The compound TQ-3 containing an electron donating amino group with two phenyl groups of the quinoline core could be accounted for by its hydrophobicity and this nature might be the reason for the noted antiplatelet effects of TQ-3. The present results provide a molecular basis for the inhibition by TQ-3 in collagen-induced platelet aggregation, through the suppression of multiple machineries of the signaling pathway. These results may suggest that TQ 3 can be considered a potential agent for the treatment of vascular diseases. PMID- 29470444 TI - Identification and Evaluation of Cytotoxicity of Peptide Liposome Incorporated Citron Extracts in an in Vitro System. AB - Abstract: Citrons have been widely used for medicinal purposes for a long time, but the application of citron in the food industry is still restricted. The extensive advantages of nanotechnology in the food industry have greatly broadened the application of foods. In this study, by employing nanotechnology, we prepared citron-extract nanoparticle with an average size of 174.11 +/- 3.89 nm, containing protein peptide and/or liposome. In order to evaluate the toxicity of nanoparticles and to ensure food safety, biological cytotoxicity at the cell and genomic levels was also identified to examine the toxicity of citron extracts by using an in vitro system. Our results demonstrated that the cytotoxicity of citronliposome was dependent on cell type in high concentrations (1 and 5 mg/mL), selectively against primary human cardiac progenitor cells (hCPCs), and human endothelial progenitor cells (hEPCs) in MTT and lactate dehydrogenase (LDH) assays. Interestingly, for the NIH-3T3 and H9C2 cell lines, cell cytotoxicity was observed with slight genotoxicity, especially from citronpeptide extract for both cell lines. Taken together, our study provides cytotoxicity data on nanoengineered citron extracts according to different cell type as is crucial for further applications. PMID- 29470446 TI - A Cross-Layer, Anomaly-Based IDS for WSN and MANET. AB - Intrusion detection system (IDS) design for mobile adhoc networks (MANET) is a crucial component for maintaining the integrity of the network. The need for rapid deployment of IDS capability with minimal data availability for training and testing is an important requirement of such systems, especially for MANETs deployed in highly dynamic scenarios, such as battlefields. This work proposes a two-level detection scheme for detecting malicious nodes in MANETs. The first level deploys dedicated sniffers working in promiscuous mode. Each sniffer utilizes a decision-tree-based classifier that generates quantities which we refer to as correctly classified instances (CCIs) every reporting time. In the second level, the CCIs are sent to an algorithmically run supernode that calculates quantities, which we refer to as the accumulated measure of fluctuation (AMoF) of the received CCIs for each node under test (NUT). A key concept that is used in this work is that the variability of the smaller size population which represents the number of malicious nodes in the network is greater than the variance of the larger size population which represents the number of normal nodes in the network. A linear regression process is then performed in parallel with the calculation of the AMoF for fitting purposes and to set a proper threshold based on the slope of the fitted lines. As a result, the malicious nodes are efficiently and effectively separated from the normal nodes. The proposed scheme is tested for various node velocities and power levels and shows promising detection performance even at low-power levels. The results presented also apply to wireless sensor networks (WSN) and represent a novel IDS scheme for such networks.

AB - We report a series of Cu(II) and Zn(II) complexes with different ligands containing a dipicolyl unit functionalized with urea groups that may contain or not a phenylboronic acid function. These complexes were designed for the recognition of phosphorylated anions through coordination to the metal ion reinforced by hydrogen bonds involving the anion and NH groups of urea. The complexes were isolated and several adducts with pyrophosphate were characterized using Xray diffraction measurements. Coordination of one of the urea nitrogen atoms to the metal ion promoted the hydrolysis of the ligands containing 1,3 diphenylurea units, while ligands bearing 1-ethyl-3-phenylurea groups did not hydrolyze significantly at room temperature. Spectrophotometric titrations, combined with 1H and 31P NMR studies, were used in investigating the binding of phosphate, pyrophosphate (PPi), and nucleoside 5'-polyphosphates (AMP, ADP, ATP, CMP, and UMP). The association constants determined in aqueous solution (pH 7.0, 0.1 M MOPS) point to a stronger association with PPi, ADP, and ATP as compared with the anions containing a single phosphate unit. The [CuL4]2+ complex shows important selectivity for pyrophosphate (PPi) over ADP and ATP.

AB - This paper describes a multichannel super-heterodyne signal analyzer, called the Spectrum Analysis Solution (SAS), which performs multi-purpose spectrum sensing to support spectrally adaptive and cognitive radar applications. The SAS operates from ultrahigh frequency (UHF) to the S-band and features a wideband channel with eight narrowband channels. The wideband channel acts as a monitoring channel that can be used to tune the instantaneous band of the narrowband channels to areas of interest in the spectrum. The data collected from the SAS has been utilized to develop spectrum sensing algorithms for the budding field of spectrum sharing (SS) radar. Bandwidth (BW), average total power, percent occupancy (PO), signal to-interference-plus-noise ratio (SINR), and power spectral entropy (PSE) have been examined as metrics for the characterization of the spectrum. These metrics are utilized to determine a contiguous optimal sub-band (OSB) for a SS radar transmission in a given spectrum for different modalities. Three OSB algorithms are presented and evaluated: the spectrum sensing multi objective (SS-MO), the spectrum sensing with brute force PSE (SS-BFE), and the spectrum sensing multi objective with brute force PSE (SS-MO-BFE).

AB - Green exercise can be classified into three levels based on engagement with nature. Although this classification was proposed more than a decade ago, few studies have investigated it since. The present study examined the effects of green exercise levels on engagement with nature and physical activity (PA) through a field experiment. A questionnaire was distributed to 95 students from a technology university in Central Taiwan to measure their level of engagement with nature in people-environment transactions, while their PA was measured using three instruments. In addition, because social interaction may distract individual attention from activities or their environments, the present study incorporated the presence of partners as a control variable. The results revealed that (1) engagement with nature and PA significantly differed between the levels of green exercise, and the higher the level of green exercise participated in, the greater the level of engagement with nature; and (2) although the presence of partners did not influence the level of engagement with nature, it significantly affected the level of PA.

AB - The purpose of the study was to assess the quality of life (QoL) and satisfaction with life (SwL) of women with polycystic ovary syndrome (PCOS) in comparison with those of healthy controls, and to identify and analyze factors determining QoL and SwL in women with PCOS. The cross-sectional study was performed between January and November 2016 in 504 women using health care services in Poland. The study group comprised women with PCOS, the control group women without PCOS. The study used a diagnostic survey with questionnaires. Research instruments included the World Health Organization Quality of Life-BREF (WHOQOL-BREF) questionnaire, the satisfaction with life scale (SWLS), and a standardized interview questionnaire comprising questions on the participants' characteristics. Women with PCOS have lower QoL and SwL than healthy controls (p < 0.05). Factors affecting QoL in PCOS patients included socio-economic standing, time from PCOS diagnosis, BMI, age, and professional activity (p < 0.05). Factors affecting SwL in PCOS patients included socio-economic standing, having children, BMI, and time from PCOS diagnosis (p < 0.05). The higher the PCOS patients' QoL, the higher their SwL (p < 0.05). Further studies are required, focusing both on PCOS and its etiology, and on its impact on the women diagnosed with the disease.

AB - Whereas the topic of the 'cultural sensitivity' of healthcare systems has been addressed extensively in the US and the UK, literature on the subject in most European countries, specifically looking at the situation of Roma, is still scarce. Drawing on qualitative research conducted mainly in the city of Barcelona under the communicative approach with Roma subjects who have stable socioeconomic positions and higher cultural capitals (end-users, professionals of the healthcare system, and key informants of a regional policy oriented to the improvement of Roma living conditions), the present study aims to fill this gap. We explore the barriers that the Roma face in accessing the healthcare system, reflecting on how these barriers are accentuated by the existing anti-Roma prejudices and institutional arrangements that do not account for minority cultures. Our results point out a series of obstacles at two levels, in the interaction with healthcare professionals, and in relation to existing institutional arrangements, which prevent Roma families from having equal access to the healthcare system. Education stands up as a mechanism to contest anti-Roma sentiments among healthcare professionals. PMID- 29470451 TI - The Impacts of Regulations and Financial Development on the Operations of Supply Chains with Greenhouse Gas Emissions. AB - To establish a micro foundation to understand the impacts of greenhouse gas (GHG) emission regulations and financial development levels on firms' GHG emissions, we build a two-stage dynamic game model to incorporate GHG emission regulations (in terms of an emission tax) and financial development (represented by the corresponding financing cost) into a two-echelon supply chain. With the subgame perfect equilibrium, we identify the conditions to determine whether an emission regulatory policy and/or financial development can affect GHG emissions in the supply chain. We also reveal the impacts of the strictness of GHG emission regulation, the financial development level, and the unit GHG emission rate on the operations of the supply chain and the corresponding profitability implications. Managerial insights are also discussed. PMID- 29470453 TI - UHPLC-UV Method for Simultaneous Determination of Perindopril Arginine and Indapamide Hemihydrate in Combined Dosage Form: A Stability-Indicating Assay Method. AB - Perindopril arginine and Indapamide hemihydrate in combination were proven to have a synergistic antihypertensive impact when compared with the use of each component alone. Therefore, a new Ultra-High Performance Liquid Chromatography coupled with Ultraviolet detector (UHPLC-UV) method has been developed and subsequently validated for simultaneous determination of the anti-hypertensive combination of Perindopril arginine and Indapamide hemihydrate. The separation of Perindopril arginine and Indapamide hemihydrate was achieved using a BEH C18 (1.7 MUm, 2.1 * 50 mm) analytical column (Waters(r) Acquity UPLC) and a mobile phase composed of 0.01% v/v formic acid in water adjusted to pH 4 with acetic acid and acetonitrile (40:60 v/v). The method was able to separate Perindopril arginine and Indapamide hemihydrate within less than 4.5 min with high accuracy, precision, resolution, and sensitivity. The content of Perindopril arginine and Indapamide hemihydrate present in the dosage form Coversyl Plus(r) (5000 ug of Perindopril arginine/1250 ug of Indapamide hemihydrate) was determined in triplicate to give a concentration of 4991 ug and 1247 ug, respectively, from the manufacturer's stated amounts with Relative Standard Deviation (%RSD) of +/-0.63% for Perindopril arginine and +/-0.84% for Indapamide hemihydrate. Moreover, the degradation products of the combination were elucidated by UHPLC-Quadrupole Time of Flight-Mass spectrometry (UHPLC-QToF-MS) under acidic, basic, and thermal conditions. In conclusion, the developed UHPLC-UV method was sensitive, rapid, and precise. Furthermore, forced degradation studies were performed and the degradants were identified by UHPLC-Electro-Spray Ionization-QToF (UHPLC-ESI QToF). PMID- 29470452 TI - WHO Environmental Noise Guidelines for the European Region: A Systematic Review on Environmental Noise and Cardiovascular and Metabolic Effects: A Summary. AB - To update the current state of evidence and assess its quality, we conducted a systematic review on the effects of environmental noise exposure on the cardio metabolic systems as input for the new WHO environmental noise guidelines for the European Region. We identified 600 references relating to studies on effects of noise from road, rail and air traffic, and wind turbines on the cardio-metabolic system, published between January 2000 and August 2015. Only 61 studies, investigating different end points, included information enabling estimation of exposure response relationships. These studies were used for meta-analyses, and assessments of the quality of evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE). A majority of the studies concerned traffic noise and hypertension, but most were cross-sectional and suffering from a high risk of bias. The most comprehensive evidence was available for road traffic noise and Ischeamic Heart Diseases (IHD). Combining the results of 7 longitudinal studies revealed a Relative Risk (RR) of 1.08 (95% CI: 1.01 1.15) per 10 dB (LDEN) for the association between road traffic noise and the incidence of IHD. We rated the quality of this evidence as high. Only a few studies reported on the association between transportation noise and stroke, diabetes, and/or obesity. The quality of evidence for these associations was rated from moderate to very low, depending on transportation noise source and outcome. For a comprehensive assessment of the impact of noise exposure on the cardiovascular and metabolic system, we need more and better quality evidence, primarily based on longitudinal studies. PMID- 29470454 TI - Mineralization Induction of Gingival Fibroblasts and Construction of a Sandwich Tissue-Engineered Complex for Repairing Periodontal Defects. AB - BACKGROUND The ideal healing technique for periodontal tissue defects would involve the functional regeneration of the alveolar bone, cementum, and periodontal ligament, with new periodontal attachment formation. In this study, gingival fibroblasts were induced and a "sandwich" tissue-engineered complex (a tissue-engineered periodontal membrane between 2 tissue-engineered mineralized membranes) was constructed to repair periodontal defects. We evaluated the effects of gingival fibroblasts used as seed cells on the repair of periodontal defects and periodontal regeneration. MATERIAL AND METHODS Primitively cultured gingival fibroblasts were seeded bilaterally on Bio-Gide collagen membrane (a tissue-engineered periodontal membrane) or unilaterally on small intestinal submucosa segments, and their mineralization was induced. A tissue-engineered sandwich was constructed, comprising the tissue-engineered periodontal membrane flanked by 2 mineralized membranes. Periodontal defects in premolar regions of Beagles were repaired using the tissue-engineered sandwich or periodontal membranes. Periodontal reconstruction was compared to normal and trauma controls 10 or 20 days postoperatively. RESULTS Periodontal defects were completely repaired by the sandwich tissue-engineered complex, with intact new alveolar bone and cementum, and a new periodontal ligament, 10 days postoperatively. CONCLUSIONS The sandwich tissue-engineered complex can achieve ideal periodontal reconstruction rapidly. PMID- 29470455 TI - Urban-Rural County and State Differences in Chronic Obstructive Pulmonary Disease - United States, 2015. AB - Chronic obstructive pulmonary disease (COPD) accounts for the majority of deaths from chronic lower respiratory diseases, the third leading cause of death in the United States in 2015 and the fourth leading cause in 2016.* Major risk factors include tobacco exposure, occupational and environmental exposures, respiratory infections, and genetics.? State variations in COPD outcomes (1) suggest that it might be more common in states with large rural areas. To assess urban-rural variations in COPD prevalence, hospitalizations, and mortality; obtain county level estimates; and update state-level variations in COPD measures, CDC analyzed 2015 data from the Behavioral Risk Factor Surveillance System (BRFSS), Medicare hospital records, and death certificate data from the National Vital Statistics System (NVSS). Overall, 15.5 million adults aged >=18 years (5.9% age-adjusted prevalence) reported ever receiving a diagnosis of COPD; there were approximately 335,000 Medicare hospitalizations (11.5 per 1,000 Medicare enrollees aged >=65 years) and 150,350 deaths in which COPD was listed as the underlying cause for persons of all ages (40.3 per 100,000 population). COPD prevalence, Medicare hospitalizations, and deaths were significantly higher among persons living in rural areas than among those living in micropolitan or metropolitan areas. Among seven states in the highest quartile for all three measures, Arkansas, Kentucky, Mississippi, and West Virginia were also in the upper quartile (>=18%) for rural residents. Overcoming barriers to prevention, early diagnosis, treatment, and management of COPD with primary care provider education, Internet access, physical activity and self-management programs, and improved access to pulmonary rehabilitation and oxygen therapy are needed to improve quality of life and reduce COPD mortality.

PMID- 29470457 TI - HIV Diagnoses Among Persons Aged 13-29 Years - United States, 2010-2014. AB - In 2014, persons aged 13-29 years represented 23% of the U.S. population, yet accounted for 40% of diagnoses of human immunodeficiency virus (HIV) infection during the same year (1). During 2010-2014, the rates of diagnosis of HIV infection decreased among persons aged 15-19 years, were stable among persons aged 20-24 years, and increased among persons aged 25-29 years (1). However, these 5-year age groups encompass multiple developmental stages and potentially mask trends associated with the rapid psychosocial changes during adolescence through young adulthood. To better understand HIV infection among adolescents aged 13-17 years and young adults aged 18-29 years in the United States and identify ideal ages to target primary HIV prevention efforts, CDC analyzed data from the National HIV Surveillance System (NHSS)* using narrow age groups. During 2010-2014, rates of diagnosis of HIV infection per 100,000 population varied substantially among persons aged 13-15 years (0.7), 16-17 years (4.5), 18-19 years (16.5), and 20-21 years (28.6), and were higher, but less variable, among persons aged 22-23 years (34.0), 24-25 years (33.8), 26-27 years (31.3), and 28 29 years (28.7). In light of the remarkable increase in rates between ages 16-17, 18-19, and 20-21 years, and a recent study revealing that infection precedes diagnosis for young persons by an average of 2.7 years (2), these findings demonstrate the importance of targeting primary prevention efforts to persons aged <18 years and continuing through the period of elevated risk in their mid twenties. PMID- 29470458 TI - Prevalence of Amyotrophic Lateral Sclerosis - United States, 2014. AB - Amyotrophic lateral sclerosis (ALS), commonly known as Lou Gehrig's disease, is a progressive and fatal neuromuscular disease; the majority of ALS patients die within 2-5 years of receiving a diagnosis (1). Familial ALS, a hereditary form of the disease, accounts for 5%-10% of cases, whereas the remaining sporadic cases have no clearly defined etiology (1). ALS affects persons of all races and ethnicities; however, whites, males, non-Hispanics, persons aged >60 years, and those with a family history of ALS are more likely to develop the disease (1-3). No cure for ALS has yet been identified, and the lack of proven and effective therapeutic interventions is an ongoing challenge. Current treatments available do not cure ALS but have been shown to slow disease progression. Until recently, only one drug (riluzole) was approved to treat ALS; however, in 2017, the Food and Drug Administration approved a second drug, edaravone (4).

AB - Hypertension, which affects nearly one third of adults in the United States, is a major risk factor for heart disease and stroke (1), and only approximately half of those with hypertension have their hypertension under control (2). The prevalence of hypertension is highest among non-Hispanic blacks, whereas the prevalence of antihypertensive medication use is lowest among Hispanics (1). Geographic variations have also been identified: a recent report indicated that the Southern region of the United States had the highest prevalence of hypertension as well as the highest prevalence of medication use (3). Using data from the Behavioral Risk Factor Surveillance System (BRFSS), this study found minimal change in state-level prevalence of hypertension awareness and treatment among U.S. adults during the first half of the current decade. From 2011 to 2015, the age-standardized prevalence of self-reported hypertension decreased slightly, from 30.1% to 29.8% (p = 0.031); among those with hypertension, the age standardized prevalence of medication use also decreased slightly, from 63.0% to 61.8% (p<0.001). Persistent differences were observed by age, sex, race/ethnicity, level of education, and state of residence. Increasing hypertension awareness, as well as increasing hypertension control through lifestyle changes and consistent antihypertensive medication use, requires diverse clinical and public health intervention. PMID- 29470461 TI - Self-Reported Receipt of Advice and Action Taken To Reduce Dietary Sodium Among Adults With and Without Hypertension - Nine States and Puerto Rico, 2015. AB - Hypertension is a major cardiovascular disease risk factor (1,2). Advice given by health professionals can result in lower sodium intake and lower blood pressure (3).The 2017 Hypertension Guideline released by the American College of Cardiology and the American Heart Association emphasizes nonpharmacologic approaches, including sodium reduction, as important components of hypertension prevention and treatment (4). Data from 50,576 participants in the sodium module of the 2015 Behavioral Risk Factor Surveillance System (BRFSS) in nine states and Puerto Rico were analyzed to determine the prevalence of reported sodium reduction advice and action among participants with and without self-reported hypertension. Among participants with self-reported hypertension, adjusted prevalence of receiving sodium reduction advice from a health professional was 41.9%, compared with 12.8% among participants without hypertension. Among those with hypertension, adjusted prevalence of reported action to reduce sodium intake was 80.9% among participants who received advice and 55.7% among those who did not receive advice. Among participants without hypertension, adjusted prevalence of taking action to reduce sodium intake was 72.7% among those who received advice and 46.9% among those who did not receive advice. The provision of advice on sodium reduction by health professionals is associated with respondent action to watch or reduce sodium intake. Fewer than half of patients with hypertension received this advice from their health professionals, a circumstance that represents a substantial missed opportunity to promote hypertension prevention and treatment.

AB - During 2014-2016, 69.2% of all older adults, aged >=65 years, had received an influenza vaccine in the past 12 months. The percentage of older adults with family income >=200% poverty level who had received an influenza vaccine in the past 12 months significantly increased from 67.9% during 1999-2001 to 72.2% during 2014-2016. During the same period, the changes from 55.7% to 60.8% among those at the <100% poverty level and from 60.3% to 62.9% for those at the 100% to <200% poverty level were not statistically significant. During both periods, older adults with income >=200% poverty level were significantly more likely to receive an influenza vaccine compared with those with lower family income. PMID- 29470463 TI - Monitoring intracellular nanomolar calcium using fluorescence lifetime imaging. AB - Nanomolar-range fluctuations of intracellular [Ca2+] are critical for brain cell function but remain difficult to measure. We have advanced a microscopy technique to monitor intracellular [Ca2+] in individual cells in acute brain slices (also applicable in vivo) using fluorescence lifetime imaging (FLIM) of the Ca2+ sensitive fluorescent indicator Oregon Green BAPTA1 (OGB-1). The OGB-1 fluorescence lifetime is sensitive to [Ca2+] within the 10-500 nM range but not to other factors such as viscosity, temperature, or pH. This protocol describes the requirements, setup, and calibration of the FLIM system required for OGB-1 imaging. We provide a step-by-step procedure for whole-cell OGB-1 loading and two photon FLIM. We also describe how to analyze the obtained FLIM data using total photon count and gated-intensity record, a ratiometric photon-counting approach that provides a highly improved signal-to-noise ratio and greater sensitivity of absolute [Ca2+] readout. We demonstrate our technique in nerve cells in situ, and it is adaptable to other cell types and fluorescent indicators. This protocol requires a basic understanding of FLIM and experience in single-cell electrophysiology and cell imaging. Setting up the FLIM system takes ~2 d, and OGB-1 loading, imaging, and data analysis take 2 d. PMID- 29470464 TI - Generation of human brain region-specific organoids using a miniaturized spinning bioreactor. AB - Human brain organoids, 3D self-assembled neural tissues derived from pluripotent stem cells, are important tools for studying human brain development and related disorders. Suspension cultures maintained by spinning bioreactors allow for the growth of large organoids despite the lack of vasculature, but commercially available spinning bioreactors are bulky in size and have low throughput. Here, we describe the procedures for building the miniaturized multiwell spinning bioreactor SpinOmega from 3D-printed parts and commercially available hardware. We also describe how to use SpinOmega to generate forebrain, midbrain and hypothalamus organoids from human induced pluripotent stem cells (hiPSCs). These organoids recapitulate key dynamic features of the developing human brain at the molecular, cellular and structural levels. The reduction in culture volume, increase in throughput and reproducibility achieved using our bioreactor and region-specific differentiation protocols enable quantitative modeling of brain disorders and compound testing. This protocol takes 14-84 d to complete (depending on the type of brain region-specific organoids and desired developmental stages), and organoids can be further maintained over 200 d. Competence with hiPSC culture is required for optimal results. PMID- 29470466 TI - E-cigarettes-peering into the mist of uncertainty.

PMID- 29470465 TI - Genome-wide mapping of endogenous G-quadruplex DNA structures by chromatin immunoprecipitation and high-throughput sequencing. AB - G-rich DNA sequences can form four-stranded G-quadruplex (G4) secondary structures and are linked to fundamental biological processes such as transcription, replication and telomere maintenance. G4s are also implicated in promoting genome instability, cancer and other diseases. Here, we describe a detailed G4 ChIP-seq method that robustly enables the determination of G4 structure formation genome-wide in chromatin. This protocol adapts traditional ChIP-seq for the detection of DNA secondary structures through the use of a G4 structure-specific single-chain antibody with refinements in chromatin immunoprecipitation followed by high-throughput sequencing. This technology does not require expression of the G4 antibody in situ, enabling broad applicability to theoretically all chromatin sources. Beginning with chromatin isolation and antibody preparation, the entire protocol can be completed in <1 week, including basic computational analysis. PMID- 29470468 TI - An audit of risk assessments for suicide and attempted suicide in ED: a retrospective review of quality. AB - AIM: The primary aim of this audit was to determine the quality of psychiatric risk assessments conducted by Mental Health & Addiction Services clinicians for patients presenting to the emergency department, Waikato Hospital, Hamilton, New Zealand following an attempted suicide. METHOD: A retrospective, randomised audit of 376 files of patients who had presented to the ED over a 12-month period from 1 July 2015 to 30 June 2016 was conducted, following the standards outlined in the present New Zealand Ministry of Health Clinical Practice Guideline for Deliberate Self Harm (DSH). RESULTS: It was found that clinicians routinely focused on the historical features of the suicide attempt presentation while failing to record judgements about future suicidal behaviours. Interactions with family members were recorded in less than half of the cases. The guideline most poorly adhered to was checking whether Maori patients wanted culturally appropriate services during the assessment and treatment planning, with this recorded in less than 10% of the clinical records. CONCLUSIONS: To improve the quality of the suicide risk assessments, and to better align with Clinical Practice Guidelines, the authors propose redevelopment of clinician training, including focus on cultural competence, and training in confidentiality and privacy relating to an attempted suicide episode. PMID- 29470469 TI - Acceptability of electronic cigarettes as an option to replace tobacco smoking for alcoholics admitted to hospital for detoxification. AB - AIM: A feasibility/acceptability trial was undertaken at Ward 5, Kenepuru Hospital, Porirua, to ascertain whether electronic cigarettes (e-cigarettes) were a useful option to replace or reduce smoking in the detoxification ward. METHODS: Two groups of patients were studied. Tobacco use and dependency data were collected for each. The first group was surveyed on the usefulness of standard nicotine replacement therapy (NRT). The second group were offered e-cigarettes with the option of standard NRT as well. All were asked to record their use of cigarettes, e-cigarettes and NRT during their stay on the ward, and to comment on their experiences. Outcomes monitored were self-reported use of NRT and of tobacco. Informal impressions of the nursing staff were also collected, where offered. For the e-cigarette group, a blood sample was taken on day 3 or 4 of their stay in hospital for nicotine/cotinine analysis, to confirm nicotine intake status. RESULTS: E-cigarettes were well tolerated as a form of nicotine replacement, eliciting positive comments, though they were not effective for all. The average reduction in median cigarettes per day was very similar between the group given standard NRT and the e-cigarette group, at 80% and 86% respectively. There were no adverse effects reported. CONCLUSION: The study showed that e cigarettes were an acceptable form of nicotine replacement for these alcohol dependent patients during their time in the ward. For heavily tobacco-dependent smokers, e-cigarettes may provide a useful aid to patient management within a hospital setting. PMID- 29470470 TI - Limiting complication rates in implant-based breast reconstruction. AB - BACKGROUND: External beam radiotherapy (XRT) to the breast has been shown to increase complication rates in women undergoing implant-based breast reconstruction (IBBR). Owing to concerns about high complication and failure rates, our department began to favour autologous reconstructive in patients requiring XRT in 2013. This study assesses the outcomes of IBBR prior to and following this policy change. METHODS: The records of all patients who underwent first-stage IBBR in 2012 and 2013 in our department were reviewed. Patients undergoing peri-operative XRT were identified. Complications and failure rates were analysed. RESULTS: Over two years, 77 IBBRs were performed in 53 patients. In 2012, 11 patients underwent peri-operative XTR compared with five in 2013. Radiotherapy was significantly associated with higher reconstructive failure rates while pre-operative XRT was associated with more complications overall (p=0.0099). Over the two years, the number of IBBRs with any complication fell from 16 (43.2%) to 11 (27.5%) while reconstructive failure fell from six (16.2%) to four (10%). CONCLUSIONS: Peri-operative XRT increases complication rates and reconstructive failure with IBBR. Our current policy of recommending autologous reconstruction if they have had pre-operative XRT seems to be resulting in decreased complication rates and increased reconstructive success. PMID- 29470471 TI - E-cigarette use in New Zealand-a systematic review and narrative synthesis. AB - AIM: This study aimed to systematically review the literature on e-cigarette use in New Zealand, focusing on prevalence, rationale for use, perceptions and exposure to the devices. METHODS: Six databases were systematically searched for articles regarding e-cigarette use in New Zealand, supplemented with a grey literature search. Seven hundred and eighteen abstracts were identified and full text of 100 articles reviewed. Studies addressing prevalence of and rationale for use, perceptions of and exposure to e-cigarettes were included. Relevant data were synthesised in a narrative summary. RESULTS: Fourteen studies addressed aspects of e-cigarette use in New Zealand, published between 2010 and 2017. Ever use of e-cigarettes among adults and adolescents has increased, although current use remains low. Smoking strongly predicts use, and ever-use may decrease with age. Investigation of other predictors has been hindered by low prevalence and small samples. While curiosity is commonly cited for sampling e-cigarettes, many smokers are drawn by harm reduction or cessation. More complex motivators are becoming evident. Although exposure to e-cigarettes is common, many remain uncertain about their harm relative to tobacco. CONCLUSION: While the available evidence provides an overview of current use, exposure and acceptance of e cigarettes in New Zealand, it highlights knowledge deficits and informs future monitoring. PMID- 29470472 TI - Ethnic- and sex-related differences in pain characteristics, psychological distress and pain-related disability in patients attending a New Zealand teaching hospital pain service. AB - AIM: The aim of the present observational study was to provide a description of the demographic, psychological and pain characteristics of patients attending the Waitemata Pain Services (WPS), Auckland, New Zealand. METHOD: Data were collected via a comprehensive paper-pencil questionnaire handed out to 798 consecutive new patients seen at the WPS over a four-year period. RESULTS: 32.3% attending the WPS were men and 67.7% women, with a mean age of 52.1 years. 65.7% of patients were New Zealand Europeans, followed by 19.1% other Europeans, 5.7% Asians, 3.9% Maori, 2.8% Middle Eastern/Latin/Africans and 2.7% Pacific Islanders. Patients reported an average of 2.6 visits to the GP before presenting to the unit. Average pain duration was seven years and seven months. Women reported a significantly higher number of pain sites in the whole body, as well as in the left and right side of the body compared to men (p<0.0001 for all). Highest interference due to pain was found for enjoyment of life. Men and women further differed in a range of psycho-behavioural variables, with women reporting less psychological distress and depression but more stress compared to men (p<0.05 for all). Men showed higher levels of kinesiophobia (p<0.005) and less pain acceptance and pain willingness (p<0.05 for both). Cross-cultural comparison found Maori patients reported highest pain levels, highest number of pain sites, highest pain interference, as well as highest levels of psychological distress, depression, stress and anxiety compared to all other ethnicities. Lowest pain severity was reported for New Zealand European patients and lowest interference due to pain for Pacific Islanders. While Middle Eastern/Latin/African patients showed highest levels of kinesiophobia, Pacific Islanders had the highest tendencies to catastrophise about their pain. CONCLUSION: There are important sex and ethnicity-related differences in the clinical presentation of chronic pain patients attending a large, hospital-based New Zealand pain service. While service provision can be based on generalised guidelines, specific interventions should be informed by important demographic and cultural variables. Studies are needed to identify strategies to improve service delivery in subgroups of the population who may be undertreated or lack access to appropriate interventions. PMID- 29470473 TI - Liver abscess: contemporary presentation and management in a Western population. AB - AIM: Historically, liver abscesses (LA) affected elderly, immunocompromised patients and were characterised by high morbidity and mortality, however there are no data pertaining to a New Zealand population with little information surrounding recent management trends. METHODS: A retrospective review of demographic characteristics, clinical management and microbiological data on patients presenting with liver abscess between 2005-2014 was conducted. RESULTS: Fifty-seven patients [37 males, median age 64 (range 15-87)] presented with LA and most patients were not comorbid. Ethnicity included European (47%), Chinese (16%) and Pacific Island (11%). Twenty-six patients had primary abscesses, 31 patients had secondary abscesses [biliary disease, appendicitis, diverticular disease]. Presenting symptoms were non-specific. Admission white cell count was raised in 50 (88%) of patients and 43 (75%) had a CRP>=200mg/L. All patients were investigated with CT scan with 34 LA located in the right lobe, 14 in the left and eight bi-lobar. Klebsiella pneumoniae was the commonest pathogen (26% of aspirates). Percutaneous drainage (PD) was used to treat 36 of 37 patients, 17 patients were treated with intravenous antibiotics alone and three patients required open drainage for loculated collections despite PD (n=1), intra peritoneal rupture or sepsis (n=2). Thirteen patients were readmitted within 30 days for ongoing symptoms requiring intravenous antibiotics/further PD (9) or further investigations (4). The median PD duration was 10 days (range 3-53). Twenty-six patients required follow-up imaging over one month with 16 requiring follow-up over six weeks. CONCLUSION: In a New Zealand setting, LA affect fit patients, and primary abscesses account for almost half of all presentation. PD is effective treatment in most LA although prolonged drainage and treatment with antibiotics may be necessary.

AB - AIM: Pre-hospital triage strategies aim to identify the type and extent of patient injuries and ensure that they are transferred to the most appropriate trauma centres. Despite the importance of appropriate pre-hospital transport, there is little evidence base to assist medical staff on optimal destination policy for emergent pre-hospital transport. This paper explores the spatial relationship of patient transfers prior to the implementation of the Midland Pre Hospital Trauma Destination Matrix in New Zealand, and is a retrospective view of practice against a destination policy that was applied after the study period. METHODS: We use data obtained from the Midland Trauma Registry merged with Global Positioning System (GPS) data from St John and Land Information New Zealand Data Service on major trauma occurring in 2014 and 2015. Using ArcGIS, data were analysed for spatial relationships between factors associated with major trauma events and pre-hospital transportation. RESULTS: In the retrospective analysis of 162 major trauma patients, 107 (66%) were transported to a hospital that matched the destination specified in the Matrix, and 55 (34%) were transported to a non Matrix designated hospital. CONCLUSION: Approximately one-third of patients were not directly transported to the preferred definitive care hospital subsequently defined in the Midland Pre-Hospital Trauma Destination Matrix. Ongoing monitoring of the pre-hospital transportation system and the implementation of a formal pre hospital transport policy may improve the efficiency of the Midland Trauma System. Future studies should examine the possible reasons for variations in triage decisions across the Midland Region.

AB - Since 2006 the Australian Medical Council (AMC) accreditation standards have required medical schools to comprehensively address issues related to the health of Aboriginal and Torres Strait Islander peoples in Australia, and Maori in New Zealand. This has spanned areas of staff expertise, staff and student recruitment, curriculum and institutional leadership. These Indigenous specific standards have, until now, been absent for specialist medical college accreditation. The AMC revised its accreditation standards for specialist medical colleges in 2015, and for the first time included Indigenous specific standards. This commentary presents a guideline to support Australasian medical colleges' responsiveness to these Indigenous specific standards.

AB - There has been a steady increase in cultural competency training in medical education programmes worldwide. To provide high-quality culturally competent care and reduce health disparities between Maori and non-Maori in New Zealand, several health models have been devised. The Indigenous Health Framework (IHF), currently taught at the University of Otago, Christchurch undergraduate medical programme, is a tool developed to assist health professionals to broaden their range of clinical assessment and communicate effectively with Maori patients and whanau, thereby improving health outcomes and reducing disparities. The authors of this article present a Maori health case study written from the observations of a trainee intern (first author) using components from the IHF to address health disparities between Maori and non-Maori.

AB - Asthma affects a large number of patients in China, but comprehensive evaluation of risks associated with poor asthma control in asthmatic patients with nasal diseases was still limited. We conducted this study to provide a comprehensive estimate of asthma control in Chinese asthma patients with combined nasal diseases, to explore the effect of kinds of nasal diseases on the asthma control, and to identify risk factors associated with uncontrolled asthmatic patients with combined nasal diseases. 1756 asthma patients concomitant with nasal diseases aged >=17 years and representing all regions of mainland China were surveyed. Multivariate logistic regression model with all related demographic characteristics and disease characteristics factors entered was used to identify risk factors associated with uncontrolled asthma. 56.4% of asthmatic patients with combined allergic rhinitis or rhinosinusitis or rhinopolyp remained uncontrolled. Concomitant without allergic rhinitis, younger age, better treatment adherence and higher education level might positively impact asthma control among asthmatic patients with combined nasal diseases. Perennial allergic rhinitis (OR = 1.5, P = 0.021), moderate-severe allergic rhinitis (OR = 2.2, P = 0.001) were all found to significantly increase the risk of uncontrolled asthma among asthma patients with combined allergic rhinitis. The high prevalence of uncontrolled asthma indicates that asthma management among adult Chinese asthmatic patients comorbid with nasal disease is still a challenge. Efforts should be made to raise the awareness of asthma management and to provide sufficient treatment will greatly contribute to improved quality of asthma management. It is possible to minimize the influence of allergic rhinitis on asthma control by improving nasal function, especially for more severe allergic rhinitis and perennial allergic rhinitis.

AB - Innovative human immunodeficiency virus (HIV) testing services will be needed to achieve the first 90 (90% of HIV-positive persons aware of their infection status) of the 90-90-90 target in China. Here, we describe an internet-based urine delivery testing service delivered through three pilot drugstores in Beijing that send specimens to a designated laboratory for HIV. From May 2016 to January 2017, we provided 500 HIV urine-testing service packs for display at the drugstores, and a total of 430 (86.0%) urine specimens were mailed back. All of the 430 urine specimens were of good quality and were tested. 70 urine specimens were HIV positive, showing a 16.3% (70/430) positivity rate. A total of 94.3% (66/70) of the HIV-positive participants obtained their test results through the internet, and 69.7% (46/66) of these participants received follow-up care. A total of 40 out of 46 (87.0%) participants agreed to have their results confirmed by a blood test, and 39 out of 40 (97.5%) participants were confirmed as HIV-1 positive, including two individuals that were previously diagnosed. Lastly, 28 out of 37 (75.7%) of the study participants were referred to the hospital and provided free antiviral treatment. Our data indicate that this innovative HIV testing service is effective and play an important role in HIV testing and surveillance. PMID- 29470486 TI - Lassa fever-induced sensorineural hearing loss: A neglected public health and social burden. AB - Although an association between Lassa fever (LF) and sudden-onset sensorineural hearing loss (SNHL) was confirmed clinically in 1990, the prevalence of LF induced SNHL in endemic countries is still underestimated. LF, a viral hemorrhagic fever disease caused by Lassa virus (LASV), is endemic in West Africa, causing an estimated 500,000 cases and 5,000 deaths per year. Sudden onset SNHL, one complication of LF, occurs in approximately one-third of survivors and constitutes a neglected public health and social burden. In the endemic countries, where access to hearing aids is limited, SNHL results in a decline of the quality of life for those affected. In addition, hearing loss costs Nigeria approximately 43 million dollars per year. The epidemiology of LF induced SNHL has not been characterized well. The complication of LF induced by SNHL is also an important consideration for vaccine development and treatments. However, research into the mechanism has been hindered by the lack of autopsy samples and relevant small animal models. Recently, the first animal model that mimics the symptoms of SNHL associated with LF was developed. Preliminary data from the new animal model as well as the clinical case studies support the mechanism of immune-mediated injury that causes SNHL in LF patients. This article summarizes clinical findings of hearing loss in LF patients highlighting the association between LASV infection and SNHL as well as the potential mechanism(s) for LF-induced SNHL. Further research is necessary to identify the mechanism and the epidemiology of LF-induced SNHL. PMID- 29470487 TI - Sex: Not all that it's cracked up to be? PMID- 29470488 TI - Intracellular amyloid beta expression leads to dysregulation of the mitogen activated protein kinase and bone morphogenetic protein-2 signaling axis. AB - Alzheimer's disease (AD) is a neurodegenerative syndrome classically depicted by the parenchymal accumulation of extracellular amyloid beta plaques. However, recent findings suggest intraneuronal amyloid beta (iAbeta1-42) accumulation precedes extracellular deposition. Furthermore, the pathologic increase in iAbeta1-42 has been implicated in dysregulation of cellular mechanisms critically important in axonal transport. Owing to neuronal cell polarity, retrograde and anterograde axonal transport are essential trafficking mechanism necessary to convey membrane bound neurotransmitters, neurotrophins, and endosomes between soma and synaptic interfaces. Although iAbeta1-42 disruption of axonal transport has been implicated in dysregulation of neuronal synaptic transmission, the role of iAbeta1-42 and its influence on signal transduction involving the mitogen activated protein kinase (MAPK) and morphogenetic signaling axis are unknown. Our biochemical characterization of intracellular amyloid beta accumulation on MAPK and morphogenetic signaling have revealed increased iAbeta1-42 expression leads to significant reduction in ERK 1/2 phosphorylation and increased bone morphogenetic protein 2 dependent Smad 1/5/8 phosphorylation. Furthermore, rescue of iAbeta1-42 mediated attenuation of MAPK signaling can be accomplished with the small molecule PLX4032 as a downstream enhancer of the MAPK pathway. Consequently, our observations regarding the dysregulation of these gatekeepers of neuronal viability may have important implications in understanding the iAbeta1-42 mediated effects observed in AD. PMID- 29470489 TI - Integration of machine learning and meta-analysis identifies the transcriptomic bio-signature of mastitis disease in cattle. AB - Gram-negative bacteria such as Escherichia coli (E. coli) are assumed to be among the main agents that cause severe mastitis disease with clinical signs in dairy cattle. Rapid detection of this disease is so important in order to prevent transmission to other cows and helps to reduce inappropriate use of antibiotics. With the rapid progress in high-throughput technologies, and accumulation of various kinds of '-omics' data in public repositories, there is an opportunity to retrieve, integrate, and reanalyze these resources to improve the diagnosis and treatment of different diseases and to provide mechanistic insights into host resistance in an efficient way. Meta-analysis is a relatively inexpensive option with good potential to increase the statistical power and generalizability of single-study analysis. In the current meta-analysis research, six microarray based studies that investigate the transcriptome profile of mammary gland tissue after induced mastitis by E. coli infection were used. This meta-analysis not only reinforced the findings in individual studies, but also several novel terms including responses to hypoxia, response to drug, anti-apoptosis and positive regulation of transcription from RNA polymerase II promoter enriched by up regulated genes. Finally, in order to identify the small sets of genes that are sufficiently informative in E. coli mastitis, the differentially expressed gene introduced by meta-analysis were prioritized by using ten different attribute weighting algorithms. Twelve meta-genes were detected by the majority of attribute weighting algorithms (with weight above 0.7) as most informative genes including CXCL8 (IL8), NFKBIZ, HP, ZC3H12A, PDE4B, CASP4, CXCL2, CCL20, GRO1(CXCL1), CFB, S100A9, and S100A8. Interestingly, the results have been demonstrated that all of these genes are the key genes in the immune response, inflammation or mastitis. The Decision tree models efficiently discovered the best combination of the meta-genes as bio-signature and confirmed that some of the top-ranked genes -ZC3H12A, CXCL2, GRO, CFB- as biomarkers for E. coli mastitis (with the accuracy 83% in average). This research properly indicated that by combination of two novel data mining tools, meta-analysis and machine learning, increased power to detect most informative genes that can help to improve the diagnosis and treatment strategies for E. coli associated with mastitis in cattle. PMID- 29470490 TI - Neutralization of cholera toxin with nanoparticle decoys for treatment of cholera. AB - Diarrheal diseases are a major cause of morbidity and mortality worldwide. In many cases, antibiotic therapy is either ineffective or not recommended due to concerns about emergence of resistance. The pathogenesis of several of the most prevalent infections, including cholera and enteroxigenic Escherichia coli, is dominated by enterotoxins produced by lumen-dwelling pathogens before clearance by intestinal defenses. Toxins gain access to the host through critical host receptors, making these receptors attractive targets for alternative antimicrobial strategies that do not rely on conventional antibiotics. Here, we developed a new nanotechnology strategy as a countermeasure against cholera, one of the most important and prevalent toxin-mediated enteric infections. The key host receptor for cholera toxin, monosialotetrahexosylganglioside (GM1), was coated onto the surface of polymeric nanoparticles. The resulting GM1-polymer hybrid nanoparticles were shown to function as toxin decoys by selectively and stably binding cholera toxin, and neutralizing its actions on epithelial cells in vitro and in vivo. Furthermore, the GM1-coated nanoparticle decoys attenuated epithelial 3',5'-cyclic adenosine monophosphate production and fluid responses to infection with live Vibrio cholera in cell culture and a murine infection model. Together, these studies illustrate that the new nanotechnology-based platform can be employed as a non-traditional antimicrobial strategy for the management of enteric infections with enterotoxin-producing pathogens. PMID- 29470491 TI - Emergence of Klebsiella pneumoniae subspecies pneumoniae as a cause of septicaemia in pigs in England. AB - Between 2011 and 2014 outbreaks of septicaemia due to Klebsiella pneumoniae subspecies pneumoniae (Kpp) were diagnosed on thirteen English pig farms. The most consistent features were rapid deaths of pigs from ten-days-old to weaning, seasonal occurrence (May to September), affected farms being outdoor breeding herds and the location of all but one of the outbreaks in the East Anglia region in Eastern England. Molecular characterisation of the outbreak Kpp isolates showed that by multilocus sequencing all were sequence type 25 (ST25) of K2 capsular type with a combination of a 4.3kb plasmid (pKPMC25), three phage sequences and the rmpA virulence gene. No archived Kpp isolates of porcine origin pre-dating 2011 were identified as ST25. In 2013 there was the first detection of an outbreak Kpp isolate showing antimicrobial resistance to six antibiotics. Human infection with Kpp ST25 has not been reported in the UK. PMID- 29470492 TI - Memory functions reveal structural properties of gene regulatory networks. AB - Gene regulatory networks (GRNs) control cellular function and decision making during tissue development and homeostasis. Mathematical tools based on dynamical systems theory are often used to model these networks, but the size and complexity of these models mean that their behaviour is not always intuitive and the underlying mechanisms can be difficult to decipher. For this reason, methods that simplify and aid exploration of complex networks are necessary. To this end we develop a broadly applicable form of the Zwanzig-Mori projection. By first converting a thermodynamic state ensemble model of gene regulation into mass action reactions we derive a general method that produces a set of time evolution equations for a subset of components of a network. The influence of the rest of the network, the bulk, is captured by memory functions that describe how the subnetwork reacts to its own past state via components in the bulk. These memory functions provide probes of near-steady state dynamics, revealing information not easily accessible otherwise. We illustrate the method on a simple cross repressive transcriptional motif to show that memory functions not only simplify the analysis of the subnetwork but also have a natural interpretation. We then apply the approach to a GRN from the vertebrate neural tube, a well characterised developmental transcriptional network composed of four interacting transcription factors. The memory functions reveal the function of specific links within the neural tube network and identify features of the regulatory structure that specifically increase the robustness of the network to initial conditions. Taken together, the study provides evidence that Zwanzig-Mori projections offer powerful and effective tools for simplifying and exploring the behaviour of GRNs. PMID- 29470493 TI - Effective polyploidy causes phenotypic delay and influences bacterial evolvability. AB - Whether mutations in bacteria exhibit a noticeable delay before expressing their corresponding mutant phenotype was discussed intensively in the 1940s to 1950s, but the discussion eventually waned for lack of supportive evidence and perceived incompatibility with observed mutant distributions in fluctuation tests. Phenotypic delay in bacteria is widely assumed to be negligible, despite the lack of direct evidence. Here, we revisited the question using recombineering to introduce antibiotic resistance mutations into E. coli at defined time points and then tracking expression of the corresponding mutant phenotype over time. Contrary to previous assumptions, we found a substantial median phenotypic delay of three to four generations. We provided evidence that the primary source of this delay is multifork replication causing cells to be effectively polyploid, whereby wild-type gene copies transiently mask the phenotype of recessive mutant gene copies in the same cell. Using modeling and simulation methods, we explored the consequences of effective polyploidy for mutation rate estimation by fluctuation tests and sequencing-based methods. For recessive mutations, despite the substantial phenotypic delay, the per-copy or per-genome mutation rate is accurately estimated. However, the per-cell rate cannot be estimated by existing methods. Finally, with a mathematical model, we showed that effective polyploidy increases the frequency of costly recessive mutations in the standing genetic variation (SGV), and thus their potential contribution to evolutionary adaptation, while drastically reducing the chance that de novo recessive mutations can rescue populations facing a harsh environmental change such as antibiotic treatment. Overall, we have identified phenotypic delay and effective polyploidy as previously overlooked but essential components in bacterial evolvability, including antibiotic resistance evolution. PMID- 29470494 TI - Fish mutant, where is thy phenotype? PMID- 29470495 TI - Reproducibility of preclinical animal research improves with heterogeneity of study samples. AB - Single-laboratory studies conducted under highly standardized conditions are the gold standard in preclinical animal research. Using simulations based on 440 preclinical studies across 13 different interventions in animal models of stroke, myocardial infarction, and breast cancer, we compared the accuracy of effect size estimates between single-laboratory and multi-laboratory study designs. Single laboratory studies generally failed to predict effect size accurately, and larger sample sizes rendered effect size estimates even less accurate. By contrast, multi-laboratory designs including as few as 2 to 4 laboratories increased coverage probability by up to 42 percentage points without a need for larger sample sizes. These findings demonstrate that within-study standardization is a major cause of poor reproducibility. More representative study samples are required to improve the external validity and reproducibility of preclinical animal research and to prevent wasting animals and resources for inconclusive research. PMID- 29470496 TI - Reduced-order modeling of soft robots. AB - We present a general strategy for the modeling and simulation-based control of soft robots. Although the presented methodology is completely general, we restrict ourselves to the analysis of a model robot made of hyperelastic materials and actuated by cables or tendons. To comply with the stringent real time constraints imposed by control algorithms, a reduced-order modeling strategy is proposed that allows to minimize the amount of online CPU cost. Instead, an offline training procedure is proposed that allows to determine a sort of response surface that characterizes the response of the robot. Contrarily to existing strategies, the proposed methodology allows for a fully non-linear modeling of the soft material in a hyperelastic setting as well as a fully non linear kinematic description of the movement without any restriction nor simplifying assumption. Examples of different configurations of the robot were analyzed that show the appeal of the method. PMID- 29470497 TI - Most yeast SH3 domains bind peptide targets with high intrinsic specificity. AB - A need exists to develop bioinformatics for predicting differences in protein function, especially for members of a domain family who share a common fold, yet are found in a diverse array of proteins. Many domain families have been conserved over large evolutionary spans and representative genomic data during these periods are now available. This allows a simple method for grouping domain sequences to reveal common and unique/specific binding residues. As such, we hypothesize that sequence alignment analysis of the yeast SH3 domain family across ancestral species in the fungal kingdom can determine whether each member encodes specific information to bind unique peptide targets. With this approach, we identify important specific residues for a given domain as those that show little conservation within an alignment of yeast domain family members (paralogs) but are conserved in an alignment of its direct relatives (orthologs). We find most of the yeast SH3 domain family members have maintained unique amino acid conservation patterns that suggest they bind peptide targets with high intrinsic specificity through varying degrees of non-canonical recognition. For a minority of domains, we predict a less diverse binding surface, likely requiring additional factors to bind targets specifically. We observe that our predictions are consistent with high throughput binding data, which suggests our approach can probe intrinsic binding specificity in any other interaction domain family that is maintained during evolution. PMID- 29470498 TI - U-shaped association between sleep duration and urinary albumin excretion in Korean adults: 2011-2014 Korea National Health and Nutrition Examination Survey. AB - Although sleep duration has been extensively studied in metabolic diseases, few studies have investigated the impact of sleep duration on chronic kidney disease. The aim of this study was to examine the relationship between sleep duration and albuminuria in the general population. Among 24,948 adults who participated in the 2011-2014 KNHANES, a total of 19,994 subjects were included in this analysis. Subjects were categorized into the following five groups according to self reported sleep duration: less than 5 h, 6 h, 7 h, 8 h, and more than 9 h. The association between sleep duration and urinary albumin-creatinine ratio (UACR) was examined cross-sectionally. Subjects with both short and long sleep durations were significantly associated with higher UACR levels and higher proportions of patients with microalbuminuria (30-299 mg/g) and macroalbuminuria (>=300 mg/g) compared to those with a sleep duration of 7 hours. The U-shaped association between sleep duration and UACR remained significant even after adjustment for potential confounders, including age, sex, body mass index, smoking, alcohol, education, income, exercise, estimated glomerular filtration rate, diabetes mellitus, hypertension and hypercholesterolemia. The U-shaped association is more evident in the subgroup aged 65 or older, or in female subjects. Our findings suggest that both short and long sleep durations have a U-shaped association with UACR levels in the general population, independent of potential confounders. PMID- 29470499 TI - Unveiling relationships between crime and property in England and Wales via density scale-adjusted metrics and network tools. AB - Scale-adjusted metrics (SAMs) are a significant achievement of the urban scaling hypothesis. SAMs remove the inherent biases of per capita measures computed in the absence of isometric allometries. However, this approach is limited to urban areas, while a large portion of the world's population still lives outside cities and rural areas dominate land use worldwide. Here, we extend the concept of SAMs to population density scale-adjusted metrics (DSAMs) to reveal relationships among different types of crime and property metrics. Our approach allows all human environments to be considered, avoids problems in the definition of urban areas, and accounts for the heterogeneity of population distributions within urban regions. By combining DSAMs, cross-correlation, and complex network analysis, we find that crime and property types have intricate and hierarchically organized relationships leading to some striking conclusions. Drugs and burglary had uncorrelated DSAMs and, to the extent property transaction values are indicators of affluence, twelve out of fourteen crime metrics showed no evidence of specifically targeting affluence. Burglary and robbery were the most connected in our network analysis and the modular structures suggest an alternative to "zero-tolerance" policies by unveiling the crime and/or property types most likely to affect each other. PMID- 29470500 TI - Glutathionylation of dengue and Zika NS5 proteins affects guanylyltransferase and RNA dependent RNA polymerase activities. AB - It has been estimated for dengue infection that the global population at risk is 3.5 billion people, which makes dengue an important public health problem. The causative agents of dengue are dengue viruses. For dengue virus replication, the dengue virus NS5 protein is of special importance as it has several enzyme activities important for viral replication. Previous reports of phosphorylation and SUMOylation of dengue NS5 have shown these protein modifications have important consequences for NS5 functions. In this report we identify glutathionylation, another reversible post translation modification that impacts on NS5 enzyme activity. Using dengue virus infected cells we employed specific antibodies and mass spectrometry to identify 3 cysteine residues of NS5 protein as being glutathionylated. Glutathionylation is a post translational protein modification where glutathione is covalently attached to a cysteine residue. We showed glutathionylation occurs on 3 conserved cysteine residues of dengue NS5. Then we generated two flavivirus recombinant full length proteins, dengue NS5 and Zika NS5, to characterize two of the NS5 enzyme activities, namely, guanylyltransferase and RNA-dependent RNA polymerase activities. We show glutathionylation of dengue and Zika NS5 affects enzyme activities of the two flavivirus proteins. The data suggests that glutathionylation is a general feature of the flavivirus NS5 protein and the modification has the potential to modulate several of the NS5 enzyme functions. PMID- 29470501 TI - Tissue-specific and mosaic imprinting defects underlie opposite congenital growth disorders in mice. AB - Differential DNA methylation defects of H19/IGF2 are associated with congenital growth disorders characterized by opposite clinical pictures. Due to structural differences between human and mouse, the mechanisms by which mutations of the H19/IGF2 Imprinting Control region (IC1) result in these diseases are undefined. To address this issue, we previously generated a mouse line carrying a humanized IC1 (hIC1) and now replaced the wildtype with a mutant IC1 identified in the overgrowth-associated Beckwith-Wiedemann syndrome. The new humanized mouse line shows pre/post-natal overgrowth on maternal transmission and pre/post-natal undergrowth on paternal transmission of the mutation. The mutant hIC1 acquires abnormal methylation during development causing opposite H19/Igf2 imprinting defects on maternal and paternal chromosomes. Differential and possibly mosaic Igf2 expression and imprinting is associated with asymmetric growth of bilateral organs. Furthermore, tissue-specific imprinting defects result in deficient liver and placenta-derived Igf2 on paternal transmission and excessive Igf2 in peripheral tissues on maternal transmission, providing a possible molecular explanation for imprinting-associated and phenotypically contrasting growth disorders. PMID- 29470502 TI - Chronic Obstructive Pulmonary Disease (COPD) as a disease of early aging: Evidence from the EpiChron Cohort. AB - BACKGROUND: Aging is an important risk factor for most chronic diseases. Patients with COPD develop more comorbidities than non-COPD subjects. We hypothesized that the development of comorbidities characteristically affecting the elderly occur at an earlier age in subjects with the diagnosis of COPD. METHODS AND FINDINGS: We included all subjects carrying the diagnosis of COPD (n = 27,617), and a similar number of age and sex matched individuals without the diagnosis, extracted from the 727,241 records of individuals 40 years and older included in the EpiChron Cohort (Aragon, Spain). We compared the cumulative number of comorbidities, their prevalence and the mortality risk between both groups. Using network analysis, we explored the connectivity between comorbidities and the most influential comorbidities in both groups. We divided the groups into 5 incremental age categories and compared their comorbidity networks. We then selected those comorbidities known to affect primarily the elderly and compared their prevalence across the 5 age groups. In addition, we replicated the analysis in the smokers' subgroup to correct for the confounding effect of cigarette smoking. Subjects with COPD had more comorbidities and died at a younger age compared to controls. Comparison of both cohorts across 5 incremental age groups showed that the number of comorbidities, the prevalence of diseases characteristic of aging and network's density for the COPD group aged 56-65 were similar to those of non-COPD 15 to 20 years older. The findings persisted after adjusting for smoking. CONCLUSION: Multimorbidity increases with age but in patients carrying the diagnosis of COPD, these comorbidities are seen at an earlier age. PMID- 29470503 TI - Sevoflurane posttreatment prevents oxidative and inflammatory injury in ventilator-induced lung injury. AB - Mechanical ventilation is a life-saving clinical treatment but it can induce or aggravate lung injury. New therapeutic strategies, aimed at reducing the negative effects of mechanical ventilation such as excessive production of reactive oxygen species, release of pro-inflammatory cytokines, and transmigration as well as activation of neutrophil cells, are needed to improve the clinical outcome of ventilated patients. Though the inhaled anesthetic sevoflurane is known to exert organ-protective effects, little is known about the potential of sevoflurane therapy in ventilator-induced lung injury. This study focused on the effects of delayed sevoflurane application in mechanically ventilated C57BL/6N mice. Lung function, lung injury, oxidative stress, and inflammatory parameters were analyzed and compared between non-ventilated and ventilated groups with or without sevoflurane anesthesia. Mechanical ventilation led to a substantial induction of lung injury, reactive oxygen species production, pro-inflammatory cytokine release, and neutrophil influx. In contrast, sevoflurane posttreatment time dependently reduced histological signs of lung injury. Most interestingly, increased production of reactive oxygen species was clearly inhibited in all sevoflurane posttreatment groups. Likewise, the release of the pro-inflammatory cytokines interleukin-1beta and MIP-1beta and neutrophil transmigration were completely prevented by sevoflurane independent of the onset of sevoflurane administration. In conclusion, sevoflurane posttreatment time dependently limits lung injury, and oxidative and pro-inflammatory responses are clearly prevented by sevoflurane irrespective of the onset of posttreatment. These findings underline the therapeutic potential of sevoflurane treatment in ventilator induced lung injury. PMID- 29470504 TI - Predicting the duration of reach-to-grasp movements to objects with asymmetric contact surfaces. AB - The duration of reach-to-grasp movements is influenced by the size of the contact surfaces, such that grasping objects with smaller contact surface areas takes longer. But what is the influence of asymmetric contact surfaces? In Experiment 1a, participants reached-to-lift wooden blocks off a table top, with the contact locations for the thumb and index finger varying in surface size. The time taken to lift the block was driven primarily by the thumb contact surface, which showed a larger effect size for the dependent variable of movement duration than the index finger's contact surface. In Experiment 1b participants reached-to-grasp (but not lift) the blocks. The same effect was found with duration being largely driven by contact surface size for the thumb. Experiment 2 tested whether this finding generalised to movements towards conical frusta grasped in a different plane mounted off the table top. Experiment 2 showed that movement duration again was dictated primarily by the size of the thumb's contact surface. The thumb contact surface was the visible surface in experiments 1 and 2 so Experiment 3 explored grasping when the index finger's contact surface was visible (participants grasped the frusta with the index finger at the top). An interaction between thumb and finger surface size was now found to determine movement duration. These findings provide the first empirical report of the impact of asymmetric contact surfaces on prehension, and may have implications for scientists who wish to model reach-to-grasp behaviours. PMID- 29470505 TI - Grunting's competitive advantage: Considerations of force and distraction. AB - BACKGROUND: Grunting is pervasive in many athletic contests, and empirical evidence suggests that it may result in one exerting more physical force. It may also distract one's opponent. That grunts can distract was supported by a study showing that it led to an opponent being slower and more error prone when viewing tennis shots. An alternative explanation was that grunting masks the sound of a ball being hit. The present study provides evidence against this alternative explanation by testing the effect of grunting in a sport-mixed martial arts-where distraction, rather than masking, is the most likely mechanism. METHODOLOGY/PRINCIPAL FINDINGS: We first confirmed that kicking force is increased when a grunt is performed (Experiment 1), and then adapted methodology used in the tennis study to mixed martial arts (Experiment 2). Lifting the foot to kick is a silent act, and therefore there is nothing for a grunt to mask, i.e., its effect on an opponent's response time and/or accuracy can likely be attributed to attentional distraction. Participants viewed videos of a trained mixed martial artist kicking that included, or did not include, a simulated grunt. The task was to determine as quickly as possible whether the kick was traveling upward or downward. Overall, and replicating the tennis finding, the present results indicate that a participant's response to a kick was delayed and more error prone when a simulated grunt was present. CONCLUSIONS/SIGNIFICANCE: The present findings indicate that simulated grunting may distract an opponent, leading to slower and more error prone responses. The implications for martial arts in particular, and the broader question of whether grunting should be perceived as 'cheating' in sports, are examined. PMID- 29470506 TI - Cuticular hydrocarbons correlate with queen reproductive status in native and invasive Argentine ants (Linepithema humile, Mayr). AB - In insect societies, chemical communication plays an important role in colony reproduction and individual social status. Many studies have indicated that cuticular hydrocarbons (CHCs) are the main chemical compounds encoding reproductive status. However, these studies have largely focused on queenless or monogynous species whose workers are capable of egg laying and have mainly explored the mechanisms underlying queen-worker or worker-worker reproductive conflicts. Less is known about what occurs in highly polygynous ant species with permanently sterile workers. Here, we used the Argentine ant as a model to examine the role of CHCs in communicating reproductive information in such insect societies. The Argentine ant is unicolonial, highly polygynous, and polydomous. We identified several CHCs whose presence and levels were correlated with queen age, reproductive status, and fertility. Our results also provide new insights into queen executions in the Argentine ant, a distinctive feature displayed by this species in its introduced range. Each spring, just before new sexuals appear, workers eliminate up to 90% of the mated queens in their colonies. We discovered that queens that survived execution had different CHC profiles from queens present before and during execution. More specifically, levels of some CHCs were higher in the survivors, suggesting that workers could eliminate queens based on their chemical profiles. In addition, queen CHC profiles differed based on season and species range (native vs. introduced). Overall, the results of this study provide new evidence that CHCs serve as queen signals and do more than just regulate worker reproduction.

AB - Effective inhibitors of invasion and metastasis represent a serious unmet clinical need. We have recently identified 4-fluoro-3',4',5'-trimethoxychalcone or C16 as a potent anti-invasive molecule. In this paper, we report on the development of an optimized vehicle for oral administration of C16. We also explore its pharmacokinetic and toxicity profile in rodents as a prelude to a broad-scope evaluation as a pharmacological tool in animal models of disease. C16 showed suboptimal pharmacokinetics with limited oral bioavailability and whole blood stability. Rapid metabolism with elimination via glutathione conjugation was observed. An oral dosing routine using medicated gels was developed to overcome bioavailability issues and yielded sustained whole blood levels above the half maximal effective concentration (EC50) in a 7-day study. The compound proved well-tolerated in acute and chronic experiments at 300 mg/kg PO dosing. The medicated gel formulation is highly suitable for evaluation of C16 in animal models of disease.

AB - OBJECTIVES: Increasingly more women conceive on antiretroviral therapy (ART) with non-nucleoside reverse transcriptase-based regimens. This study assessed the effect of preconception tenofovir disoproxil fumarate (TDF)-lamivudine (3TC)/emtricitabine (FTC)-efavirenz (EFV) and post-conception TDF-(3TC/FTC)-EFV (versus other regimens) on preterm delivery (PTD) and small-for-gestational age (SGA) births. METHODS: We analysed data of 2549 HIV-infected women attending antenatal clinics in KwaZulu-Natal from 2010 through 2015 in this retrospective cohort study. Preconception, TDF-(3TC/FTC)-EFV was compared to nevirapine (NVP) based regimens and other 3-drug EFV-based regimens. Post-conception, TDF (3TC/FTC)-EFV was compared to NVP-based ART and zidovudine (ZDV) prophylaxis. Outcomes included PTD <37 weeks and SGA births. Generalized linear mixed effects were used to fit logistic regression models to account for repeat pregnancies. RESULTS: Among 2549 singleton live births, 10.4% (n = 264) were PTD and 10.4% (n = 265) SGA. PTD declined from 16.3% in 2010 to 9.3% in 2015 and SGA remained stable from 9.9% in 2010 to 10% in 2015. Preconception NVP-based regimens [adjusted odds ratio (aOR) 0.66; 95% CI 0.27-1.63] and other 3-drug EFV-based regimens (aOR 0.72; 95% CI 0.24-2.12) were not associated with PTD versus TDF (3TC/FTC)-EFV. NVP-based (aOR 0.75; 95% CI 0.40-1.42) and other 3-drug EFV-based regimens (aOR 1.55; 95% CI 0.76-3.16) were not associated with SGA births versus TDF-(3TC/FTC)-EFV. Post-conception NVP-based ART (1.77; 95% CI 0.89-3.51) and ZDV (1.03; 95% CI 0.68-1.58) were not associated with PTD versus TDF-(3TC/FTC)-EFV. NVP-based ART (1.55; 95% CI 0.66-3.61) and ZDV (0.89; 95% CI 0.53-1.47) were not associated with SGA versus TDF-(3TC/FTC)-EFV. CONCLUSIONS: Preconception TDF (3TC/FTC)-EFV and post-conception TDF-(3TC/FTC)-EFV were not associated with PTD or SGA, compared with other regimens. Increasing ART use merits further study of the optimum ART regimen for safe birth outcomes. PMID- 29470509 TI - Co-circulation of all the four dengue virus serotypes and detection of a novel clade of DENV-4 (genotype I) virus in Pune, India during 2016 season. AB - Dengue is the most common mosquito-borne viral infection in tropical and sub tropical countries. In recent years, India has reported increased incidences of concurrent infection with multiple serotypes of dengue viruses (DENV). In the present study, we have characterized DENV circulating during a single season of 2016 in Pune, India. A total of 64 serum samples from NS1 ELISA positive dengue patients were used for PCR amplification of CprM region of the viral genome and sequencing. Phylogenetic analysis documented circulation of all the four DENV serotypes with predominance of DENV-2 (40.6%). DENV genotyping classified DENV-1 to Genotype V, DENV-2 to Genotype IV, DENV-3 to Genotype III and DENV-4 to Genotype I. Further analysis revealed emergence of a novel clade (D) of genotype I of DENV-4. Subsequent isolation of three DENV-4 viruses in cell culture followed by complete genome sequence analysis confirmed this observation. Additionally, a new genotype within serotype-4 with >6.7% sequence variation from other genotypes was identified. This first report of significant co-circulation of all the four serotypes in a single outbreak in Pune reconfirms need for molecular monitoring of DENV. PMID- 29470510 TI - Impacts of the active layer on runoff in an upland permafrost basin, northern Tibetan Plateau. AB - The paucity of studies on permafrost runoff generation processes, especially in mountain permafrost, constrains the understanding of permafrost hydrology and prediction of hydrological responses to permafrost degradation. This study investigated runoff generation processes, in addition to the contribution of summer thaw depth, soil temperature, soil moisture, and precipitation to streamflow in a small upland permafrost basin in the northern Tibetan Plateau. Results indicated that the thawing period and the duration of the zero-curtain were longer in permafrost of the northern Tibetan Plateau than in the Arctic. Limited snowmelt delayed the initiation of surface runoff in the peat permafrost in the study area. The runoff displayed intermittent generation, with the duration of most runoff events lasting less than 24 h. Precipitation without runoff generation was generally correlated with lower soil moisture conditions. Combined analysis suggested runoff generation in this region was controlled by soil temperature, thaw depth, precipitation frequency and amount, and antecedent soil moisture. This study serves as an important baseline to evaluate future environmental changes on the Tibetan Plateau. PMID- 29470511 TI - Preliminary analysis of proteome alterations in non-aneurysmal, internal mammary artery tissue from patients with abdominal aortic aneurysms. AB - OBJECTIVE: The pathogenesis of abdominal aortic aneurysms (AAA) involves a disturbed balance of breakdown and buildup of arterial proteins. We envision that individuals with AAA carry generalized arterial protein alterations either because of effects of genetically or environmental AAA risk factors or because of compensatory changes due to signaling molecules released from the affected aneurysmal tissue. APPROACH: Protein extraction and quantitative proteome analysis by LC-MS/MS (liquid chromatography-mass spectrometry) was done on individual samples from the internal mammary artery from 11 individuals with AAA and 33 sex- and age-matched controls without AAA. Samples were selected from a biobank of leftover internal mammary arterial tissue gathered at coronary by-pass operations. RESULTS: We identified and quantitated 877 proteins, of which 44 were differentially expressed between the two groups (nominal p-values without correction for multiple testing). Some proteins related to the extracellular matrix displayed altered concentrations in the AAA group, particularly among elastin-related molecules [elastin, microfibrillar-associated protein 4 (MFAP4), lysyl oxidase]. In addition, several histones e.g. (e.g. HIST1H1E, HIST1H2BB) and other vascular cell proteins (e.g. versican, type VI collagen) were altered. CONCLUSIONS: Our results support the notion that generalized alterations occur in the arterial tree in patients with AAA. Elastin-related proteins and histones seem to be part of such changes, however these preliminary results require replication in an independent set of specimens and validation by functional studies. PMID- 29470512 TI - Association between HIV status and depressive symptoms among children and adolescents in the Southern Highlands Zone, Tanzania: A case-control study. AB - BACKGROUND: Children and adolescents continue to have HIV/AIDS in southern Saharan Africa. Scaling up of HIV services has significantly improved access to ARV and consequently improved on morbidity and mortality related to HIV/AIDS including opportunistic infection. Despite the above efforts, non-communicable conditions including mental disorders such as depression have been observed to contribute to the burden of disabilities about which little is documented. This study, therefore, aimed to determine the magnitude of depressive symptoms and the associated factors among HIV-infected children and adolescents. METHODS: The study was a matched case-control design involving 300 cases of HIV-infected children matched by age and sex against 600 uninfected controls. Systematic sampling technique was used to select the cases while multistage sampling technique was employed to identify villages/ streets purposive and sampling technique was employed to obtain participants from households. RESULTS: The overall prevalence of depressive symptoms among the cohort of 900 participants was found to be 12.9%, with 27% of HIV-infected and 5.8% of HIV-uninfected children and adolescents screened positive for depressive symptoms. Multiple logistic regression revealed that being HIV-infected (AOR 1.96(1.11-3.45)), residing in a rural setting (AOR 0.61(0.39-0.96)) and history of childhood deprivation (AOR 4.76 (2.79-8.13)) were significantly associated with depressive symptoms. CONCLUSION: HIV infected adolescents are more affected by depression compared to non-infected counterparts. Childhood deprivation was significantly associated with presence of depressive symptoms. Integration of mental health evaluation and treatment into the HIV care provided for adolescents can be beneficial. More studies to delineate factors associated with depressed adolescents with HIV may add value to the body of knowledge and overall improvement of care.

AB - BACKGROUND: Suicidal behaviour remains challenging for clinicians to predict, with few established risk factors and warning signs among psychiatric patients. AIM: We aimed to describe characteristics and identify risk factors for suicide attempts among patients with psychiatric disorders. METHODS: Multivariable logistic regression analysis, adjusted for clinically important confounders, was employed to determine risk factors for suicide attempts within a psychiatric patient population. RESULTS: The case (n = 146) and control groups (n = 104) did not differ significantly with regards to sociodemographic characteristics. The majority of the participants who had attempted suicide did so with high intent to die, and expected to die without medical intervention. The primary method of attempt was pharmaceutical overdose among the case participants (73.3%). Results showed impulsivity (odds ratio [OR] = 1.15, 95% confidence interval [CI] = 1.03 1.30) and borderline personality symptoms (OR = 1.07, 95% CI = 1.01-1.13) were significantly associated with attempted suicide. CONCLUSIONS: Our findings indicate that known sociodemographic risk factors for suicide may not apply within psychiatric populations. Prevention strategies for suicidal behaviour in psychiatric patients may be effective, including limited access to means for suicide attempts (i.e. excess pharmaceutical drugs) and target screening for high risk personality and impulsivity traits. PMID- 29470513 TI - Offspring sex impacts DNA methylation and gene expression in placentae from women with diabetes during pregnancy. AB - AIMS/HYPOTHESIS: We hypothesized that diabetes during pregnancy (DDP) alters genome-wide DNA methylation in placenta resulting in differentially methylated loci of metabolically relevant genes and downstream changes in RNA and protein expression. METHODS: We mapped genome-wide DNA methylation with the Infinium 450K Human Methylation Bead Chip in term fetal placentae from Native American and Hispanic women with DDP using a nested case-control design (n = 17 pairs). RNA expression and protein levels were assayed via RNA-Seq and Western Blot. RESULTS: Genome-wide DNA methylation analysis revealed 465 CpG sites with significant changes for male offspring, 247 for female offspring, and 277 for offspring of both sexes (p<0.001). Placentae from female offspring were 40% more likely to have significant gains in DNA methylation compared with placentae from male offspring exposed to DDP (p<0.001). Changes in DNA methylation corresponded to changes in RNA and protein levels for 6 genes: PIWIL3, CYBA, GSTM1, GSTM5, KCNE1 and NXN. Differential DNA methylation was detected at loci related to mitochondrial function, DNA repair, inflammation, oxidative stress. CONCLUSIONS/INTERPRETATION: These findings begin to explain mechanisms responsible for the increased risk for obesity and type 2 diabetes in offspring of mothers with DDP. PMID- 29470518 TI - Universal scaling laws in metro area election results. AB - We explain the anomaly of election results between large cities and rural areas in terms of urban scaling in the 1948-2016 US elections and in the 2016 EU referendum of the UK. The scaling curves are all universal and depend on a single parameter only, and one of the parties always shows superlinear scaling and drives the process, while the sublinear exponent of the other party is merely the consequence of probability conservation. Based on the recently developed model of urban scaling, we give a microscopic model of voter behavior in which we replace diversity characterizing humans in creative aspects with social diversity and tolerance. The model can also predict new political developments such as the fragmentation of the left and the immigration paradox. PMID- 29470516 TI - Evaluation of diagnostic methods for the detection of intestinal schistosomiasis in endemic areas with low parasite loads: Saline gradient, Helmintex, Kato-Katz and rapid urine test. AB - BACKGROUND: In some tropical countries, such as Brazil, schistosomiasis control programs have led to a significant reduction in the prevalence and parasite burden of endemic populations. In this setting, the Kato-Katz technique, as the standard diagnostic method for the diagnosis of Schistosoma mansoni infections, which involves the analysis of two slides from one fecal sample, loses its sensitivity. As a result, a significant number of infected individuals are not detected. The objective of this study was to perform extensive parasitological testing of up to three fecal samples and include a rapid urine test (POC-CCA) in a moderate prevalence area in Northern Minas Gerais, Brazil, and evaluate the performance of each test separately and in combination. METHODS AND FINDINGS: A total of 254 individuals were examined with variants of the standard Kato-Katz technique (up to18 Kato-Katz slides prepared from three fecal samples), a modified Helmintex (30 g of feces), the saline gradient (500 mg of feces), and the POC-CCA methods. We established a reference standard taking into consideration all the positive results in any of the parasitological exams. Evaluation of the parasite burden by two Kato-Katz slides confirmed that most of the individuals harbored a light infection. When additional slides and different parasitological methods were included, the estimated prevalence rose 2.3 times, from 20.4% to 45.9%. The best sensitivity was obtained with the Helmintex method (84%). All parasitological methods readily detected a high or moderate intensity of infection; however, all lost their high sensitivity in the case of low or very low intensity infections. The overall sensitivity of POC-CCA (64.9%) was similar to the six Kato-Katz slides from three fecal samples. However, POC-CCA showed low concordance (kappa = 0.34) when compared with the reference standard. CONCLUSIONS: The recommended Kato-Katz method largely underestimated the prevalence of S. mansoni infection. Because the best performance was achieved with a modified Helmintex method, this technique might serve as a more precise reference standard. An extended number of Kato-Katz slides in combination with other parasitological methods or with POC-CCA was able to detect more than 80% of egg-positive individuals; however, the rapid urine test (POC-CCA) produced a considerable percentage of false positive results.

PMID- 29470517 TI - Two essential Thioredoxins mediate apicoplast biogenesis, protein import, and gene expression in Toxoplasma gondii. AB - Apicomplexan parasites are global killers, being the causative agents of diseases like toxoplasmosis and malaria. These parasites are known to be hypersensitive to redox imbalance, yet little is understood about the cellular roles of their various redox regulators. The apicoplast, an essential plastid organelle, is a verified apicomplexan drug target. Nuclear-encoded apicoplast proteins traffic through the ER and multiple apicoplast sub-compartments to their place of function. We propose that thioredoxins contribute to the control of protein trafficking and of protein function within these apicoplast compartments. We studied the role of two Toxoplasma gondii apicoplast thioredoxins (TgATrx), both essential for parasite survival. By describing the cellular phenotypes of the conditional depletion of either of these redox regulated enzymes we show that each of them contributes to a different apicoplast biogenesis pathway. We provide evidence for TgATrx1's involvement in ER to apicoplast trafficking and TgATrx2 in the control of apicoplast gene expression components. Substrate pull-down further recognizes gene expression factors that interact with TgATrx2. We use genetic complementation to demonstrate that the function of both TgATrxs is dependent on their disulphide exchange activity. Finally, TgATrx2 is divergent from human thioredoxins. We demonstrate its activity in vitro thus providing scope for drug screening. Our study represents the first functional characterization of thioredoxins in Toxoplasma, highlights the importance of redox regulation of apicoplast functions and provides new tools to study redox biology in these parasites.

PMID- 29470520 TI - Association between expression of random gene sets and survival is evident in multiple cancer types and may be explained by sub-classification. AB - One of the goals of cancer research is to identify a set of genes that cause or control disease progression. However, although multiple such gene sets were published, these are usually in very poor agreement with each other, and very few of the genes proved to be functional therapeutic targets. Furthermore, recent findings from a breast cancer gene-expression cohort showed that sets of genes selected randomly can be used to predict survival with a much higher probability than expected. These results imply that many of the genes identified in breast cancer gene expression analysis may not be causal of cancer progression, even though they can still be highly predictive of prognosis. We performed a similar analysis on all the cancer types available in the cancer genome atlas (TCGA), namely, estimating the predictive power of random gene sets for survival. Our work shows that most cancer types exhibit the property that random selections of genes are more predictive of survival than expected. In contrast to previous work, this property is not removed by using a proliferation signature, which implies that proliferation may not always be the confounder that drives this property. We suggest one possible solution in the form of data-driven sub classification to reduce this property significantly. Our results suggest that the predictive power of random gene sets may be used to identify the existence of sub-classes in the data, and thus may allow better understanding of patient stratification. Furthermore, by reducing the observed bias this may allow more direct identification of biologically relevant, and potentially causal, genes.

PMID- 29470522 TI - Quantification of edematous changes by diffusion magnetic resonance imaging in gastrocnemius muscles after spinal nerve ligation. AB - Patients with complex regional pain syndrome (CRPS) exhibit diverse symptoms, such as neuropathic pain, allodynia, local edema and skin color changes in the affected lesion. Although nerve injury may cause CRPS, pathophysiological mechanisms underlying the syndrome are unclear, and local edema, a characteristic of CRPS, has not been evaluated quantitatively for technical reasons. Here, using a rat spinal nerve ligation-induced CRPS model, we show that edematous changes in gastrocnemius muscle can be detected quantitatively by diffusion magnetic resonance imaging (MRI). Using the line-scan diffusion spectrum on a 1.5 T clinical MR imager, we demonstrate significant elevation of the apparent diffusion coefficient (ADC) ratios in gastrocnemius muscle on the ligated versus the sham-operated rats by one day after surgery, those ratios gradually decreased over time. Meanwhile, T2 ratios in gastrocnemius muscle on the ligated rats increased gradually and significantly, peaking two weeks after surgery, and those ratios remained high and were consistent with edema. Expression of vascular endothelial growth factor (VEGF), a key regulator of blood vessel formation and function, was significantly lower in gastrocnemius muscle on the ligated versus non-ligated side, suggesting that nerve ligation promotes edematous changes and perturbs VEGF expression in target muscle. PMID- 29470523 TI - A "late-but-fitter revertant cell" explains the high frequency of revertant mosaicism in epidermolysis bullosa. AB - Revertant mosaicism, or "natural gene therapy", is the phenomenon in which germline mutations are corrected by somatic events. In recent years, revertant mosaicism has been identified in all major types of epidermolysis bullosa, the group of heritable blistering disorders caused by mutations in the genes encoding epidermal adhesion proteins. Moreover, revertant mosaicism appears to be present in all patients with a specific subtype of recessive epidermolysis bullosa. We therefore hypothesized that revertant mosaicism should be expected at least in all patients with recessive forms of epidermolysis bullosa. Naturally corrected, patient-own cells are of extreme interest for their promising therapeutic potential, and their presence in all patients would open exciting, new treatment perspectives to those patients. To test our hypothesis, we determined the probability that single nucleotide reversions occur in patients' skin using a mathematical developmental model. According to our model, reverse mutations are expected to occur frequently (estimated 216x) in each patient's skin. Reverse mutations should, however, occur early in embryogenesis to be able to drive the emergence of recognizable revertant patches, which is expected to occur in only one per ~10,000 patients. This underestimate, compared to our clinical observations, can be explained by the "late-but-fitter revertant cell" hypothesis: reverse mutations arise at later stages of development, but provide revertant cells with a selective growth advantage in vivo that drives the development of recognizable healthy skin patches. Our results can be extrapolated to any other organ with stem cell division numbers comparable to skin, which may offer novel future therapeutic options for other genetic conditions if these revertant cells can be identified and isolated. PMID- 29470525 TI - Coral reef fishes exhibit beneficial phenotypes inside marine protected areas. AB - Human fishing effort is size-selective, preferentially removing the largest individuals from harvested stocks. Intensive, size-specific fishing mortality induces directional shifts in phenotypic frequencies towards the predominance of smaller and earlier-maturing individuals, which are among the primary causes of declining fish biomass. Fish that reproduce at smaller size and younger age produce fewer, smaller, and less viable larvae, severely reducing the reproductive capacity of harvested populations. Marine protected areas (MPAs) are extensively utilized in coral reefs for fisheries management, and are thought to mitigate the impacts of size-selective fishing mortality and supplement fished stocks through larval export. However, empirical evidence of disparities in fitness-relevant phenotypes between MPAs and adjacent fished reefs is necessary to validate this assertion. Here, we compare key life-history traits in three coral-reef fishes (Acanthurus nigrofuscus, Ctenochaetus striatus, and Parupeneus multifasciatus) between MPAs and fished reefs in the Philippines. Results of our analyses support previous hypotheses regarding the impacts of MPAs on phenotypic traits. Asymptotic length (Linf) and growth rates (K) differed between conspecifics in MPAs and fished reefs, with protected populations exhibiting phenotypes that are known to confer higher fecundity. Additionally, populations demonstrated increases in length at 50% maturity (L50) inside MPAs compared to adjacent areas, although age at 50% maturity (A50) did not appear to be impacted by MPA establishment. Shifts toward advantageous phenotypes were most common in the oldest and largest MPAs, but occurred in all of the MPAs examined. These results suggest that MPAs may provide protection against the impacts of size selective harvest on life-history traits in coral-reef fishes. PMID- 29470527 TI - Value of diagnostic and therapeutic laparoscopy for patients with blunt abdominal trauma: A 10-year medical center experience. AB - Laparoscopy has been used for the diagnosis and treatment for hemodynamically stable patients with penetrating abdominal trauma. This study evaluated whether diagnostic and therapeutic laparoscopy can be used as effectively in select patients with blunt abdominal trauma. All hemodynamically stable patients undergoing operations for blunt abdominal trauma over a 10-year period (2006 2015) at a tertiary medical center were included. Patients undergoing laparotomy were categorized as group A. Patients who underwent laparoscopy were categorized as group B. The clinical outcomes of the 2 groups were compared. There were 139 patients in group A and 126 patients in group B. Group A patients were more severely injured (mean injury severity score of 23.3 vs. 18.9, P < .001) and had a higher frequency of traumatic brain injuries (25.2% vs. 14.3%, P = .039). The sensitivity and specificity of diagnostic laparoscopy for patients in group B was 99.1% and 100.0%, respectively. No non-therapeutic laparotomies were performed in group B, and the success rate of therapeutic laparoscopy was 92.0% (103/112) for patients with significant intra-abdominal injuries. Patients in the 2 groups had similar perioperative and postoperative outcomes in terms of operation times, blood loss, blood transfusion requirements, mortality, and complications (all, P > .05). Laparoscopy is a feasible and safe tool for the diagnosis and treatment of hemodynamically stable patients with blunt abdominal trauma who require surgery. PMID- 29470526 TI - Expression of Yin Yang 1 in cervical cancer and its correlation with E-cadherin expression and HPV16 E6. AB - The molecular mechanisms of normal cervical squamous epithelium advancing to cervical intraepithelial neoplasia (CIN) and eventually to cervical squamous cell carcinoma (CSCC) are largely unknown. This study explored abnormal expression of Yin Yang 1 (YY1) in cervical cancer and its correlation with the expression of E cadherin and human papillomavirus (HPV) 16 E6. YY1, E-cadherin and HPV16 E6 expression were detected by immunohistochemistry in 90 cervical tissue specimens collected from 30 patients with hysteromyoma, 15 patients with CIN I, 15 patients with CIN II-III, and 30 patients with CSCC. The H-score method was employed to measure the expression of YY1, E-cadherin and HPV16 E6. Increased expression of YY1 and HPV16 E6, and the decreased expression levels of E-cadherin were strongly associated with malignant transformation of the cervical epithelium and the histological progression of CSCC. The expression of YY1 in cervical tissues was inversely correlated with E-cadherin expression, and positively correlated with HPV16 E6 expression. Expression of YY1 in CSCC tissues was not significantly correlated with tumor differentiation, but was significantly correlated with an advanced clinical stage of CSCC. These results suggest that up-regulation of YY1 is closely associated with the progression of CSCC, and YY1 may play an important role in the pathogenesis of cervical cancer by modulating the expression of E cadherin and HPV16 E6. PMID- 29470528 TI - Linear relationship between peak and season-long abundances in insects. AB - An accurate quantitative relationship between key characteristics of an insect population, such as season-long and peak abundances, can be very useful in pest management programs. To the best of our knowledge, no such relationship has yet been established. Here we establish a predictive linear relationship between insect catch Mpw during the week of peak abundance, the length of seasonal flight period, F (number of weeks) and season-long cumulative catch (abundance) A = 0.41MpwF. The derivation of the equation is based on several general assumptions and does not involve fitting to experimental data, which implies generality of the result. A quantitative criterion for the validity of the model is presented. The equation was tested using extensive data collected on captures of male gypsy moths Lymantria dispar (L.) (Lepidoptera: Erebidae) in pheromone-baited traps during 15 years. The model was also tested using trap catch data for two species of mosquitoes, Culex pipiens (L.) (Diptera: Culicidae) and Aedes albopictus (Skuse) (Diptera: Culicidae), in Gravid and BG-sentinel mosquito traps, respectively. The simple, parameter-free equation approximates experimental data points with relative error of 13% and R2 = 0.997, across all of the species tested. For gypsy moth, we also related season-long and weekly trap catches to the daily trap catches during peak flight. We describe several usage scenarios, in which the derived relationships are employed to help link results of small scale field studies to the operational pest management programs. PMID- 29470529 TI - Xenopus: An alternative model system for identifying muco-active agents. AB - The airway epithelium in human plays a central role as the first line of defense against environmental contaminants. Most respiratory diseases such as chronic obstructive pulmonary disease (COPD), asthma, and respiratory infections, disturb normal muco-ciliary functions by stimulating the hypersecretion of mucus. Several muco-active agents have been used to treat hypersecretion symptoms in patients. Current muco-active reagents control mucus secretion by modulating either airway inflammation, cholinergic parasympathetic nerve activities or by reducing the viscosity by cleaving crosslinking in mucin and digesting DNAs in mucus. However, none of the current medication regulates mucus secretion by directly targeting airway goblet cells. The major hurdle for screening potential muco-active agents that directly affect the goblet cells, is the unavailability of in vivo model systems suitable for high-throughput screening. In this study, we developed a high-throughput in vivo model system for identifying muco-active reagents using Xenopus laevis embryos. We tested mucus secretion under various conditions and developed a screening strategy to identify potential muco-regulators. Using this novel screening technique, we identified narasin as a potential muco-regulator. Narasin treatment of developing Xenopus embryos significantly reduced mucus secretion. Furthermore, the human lung epithelial cell line, Calu-3, responded similarly to narasin treatment, validating our technique for discovering muco active reagents.

AB - INTRODUCTION: The risk of development of active TB in HIV-infected individuals is 20-37 times higher than those that are HIV negative. Poor knowledge of TB amongst people living with HIV has been associated with high transmission. OBJECTIVES: To determine the effectiveness of a new health education intervention module in improving knowledge, attitude, and practice (KAP) regarding tuberculosis among HIV patients in General Hospital Minna, Nigeria. METHODS: A randomized control trial was carried out from July 2015 to June 2017. A random number generating program was used to allocate 226 respondents into 2 groups. The intervention group received health education regarding tuberculosis using the developed module. The control group received the normal services provided for HIV patients. Data were collected from December 2015 to September 2016 at baseline, immediate post intervention, three, six and nine months. The outcome measures were knowledge, attitude, and practice. RESULTS: There was no significant difference with respect to socio-demographic characteristics, KAP of the respondents in the intervention and control group at baseline. However, there was significant improvement in knowledge in the intervention group compared to the control group, group main effect (F = (1,218) = 665.889, p = 0.001, partial ?2 = 0.753, d = 5.4); time (F = (3.605, 218) = 52.046, p = 0.001, partial ?2 = 0.193, d = 1.52) and interaction between group with time (F = (3.605, 218) = 34.028, p = 0.001, partial ?2 = 0.135, d = 1.23). Likewise, there was significant improvement in attitude, group main effect (p = 0.001, d = 1.26) and time (p = 0.001, p, d = 0.65). Similarly, there was improvement in practice, group main effect, time, and interaction of group with time (p < 0.05). CONCLUSION: The health education intervention program was effective in improving KAP regarding tuberculosis among HIV patients.

AB - BACKGROUND: The incidence of nosocomial infections from extensively drug resistant Pseudomonas aeruginosa (XDR-PA) has been increasing worldwide. We investigated the prevalence and factors associated with XDR-PA infections, including the factors that predict mortality. METHODS: We retrospectively studied a cohort of adult, hospitalized patients with P. aeruginosa (PA) infections between April and December 2014. RESULTS: Of the 255 patients with PA infections, 56 (22%) were due to XDR-PA, 32 (12.5%) to multidrug resistant Pseudomonas aeruginosa (MDR-PA), and 167 (65.5%) to non-MDR PA. Receiving total parenteral nutrition (adjusted OR [aOR] 6.21; 95% CI 1.05-36.70), prior carbapenem use (aOR 4.88; 95% CI 2.36-10.08), and prior fluoroquinolone use (aOR 3.38; 95% CI 1.44 7.97) were independently associated with the XDR-PA infections. All XDR-PA remained susceptible to colistin. Factors associated with mortality attributable to the infections were the presence of sepsis/septic shock (aOR 11.60; 95% CI 4.66-28.82), admission to a medical department (aOR 4.67; 95% CI 1.81-12.06), receiving a central venous catheter (aOR 3.78; 95% CI 1.50-9.57), and XDR-PA infection (aOR 2.73; 95% CI 1.05-7.08). CONCLUSION: The prevalence of XDR-PA infections represented almost a quarter of Pseudomonas aeruginosa hospital acquired infections and rendered a higher mortality. The prompt administration of an appropriate empirical antibiotic should be considered when an XDR-PA infection is suspected.

AB - BACKGROUND: Suicide is a serious cause of mortality worldwide and is considered as a psychiatric emergency. People living with HIV/AIDS (PLWHA) have higher rates of suicidal behavior than the general population. This study assessed the prevalence and verified the syndemic effect of psychosocial health conditions on suicidal ideation among PLWHA in China. METHODS: An institutional-based cross sectional study was conducted from July to August 2016 in Nanjing, China, using a self-report questionnaire. Sociodemographic characteristics, infection status, psychosocial variables and suicide ideation reports of participants were collected. Logistic regressions were used to identify potential factors associated with suicidal ideation and to verify the syndemic effect of psychosocial factors. Additionally, odds ratios (ORs) with 95% confidence intervals (95% CI) were computed. RESULTS: In total, four hundred sixty-five PLWHA participated, 31.6% (n = 147) of whom had suicidal ideation. The results from univariate analysis showed that older age, low education level, being married, having children, and psychosocial variables (high perceived stigma, depression, low self-esteem, social support and resilience) were significantly associated with increased suicidal ideation. Multiple logistic regression models revealed that depression (OR = 2.70, 95%CI = 1.62-4.51), perceived stigma (OR = 1.97, 95%CI = 1.17-3.32), and low social support (OR = 1.85, 95%CI = 1.08-3.20) and self-esteem (OR = 4.11, 95%CI = 2.06-8.16) were statistically significant. PLWHA with at least two psychosocial health problems were nearly 5 times more likely (OR = 4.72, 95% CI 3.11-7.17) to have had suicidal ideation. CONCLUSIONS: Suicidal ideation is frequent among PLWHA in China and is consistent with prevalence estimates from abroad. Psychosocial health problems were the determining factors associated with suicidal ideation, and a syndemic effect of psychosocial health conditions was confirmed in predicting suicidal ideation. Therefore, early screening of high-risk groups for suicidal ideation and more psychosocial health care among PLWHA are needed.

AB - Respiratory syncytial virus (RSV) is a major human pathogen that infects the majority of children by two years of age. The RSV fusion (F) protein is a primary target of human antibodies, and it has several antigenic regions capable of inducing neutralizing antibodies. Antigenic site IV is preserved in both the pre fusion and post-fusion conformations of RSV F. Antibodies to antigenic site IV have been described that bind and neutralize both RSV and human metapneumovirus (hMPV). To explore the diversity of binding modes at antigenic site IV, we generated a panel of four new human monoclonal antibodies (mAbs) and competition binding suggested the mAbs bind at antigenic site IV. Mutagenesis experiments revealed that binding and neutralization of two mAbs (3M3 and 6F18) depended on arginine (R) residue R429. We discovered two R429-independent mAbs (17E10 and 2N6) at this site that neutralized an RSV R429A mutant strain, and one of these mAbs (17E10) neutralized both RSV and hMPV. To determine the mechanism of cross reactivity, we performed competition-binding, recombinant protein mutagenesis, peptide binding, and electron microscopy experiments. It was determined that the human cross-reactive mAb 17E10 binds to RSV F with a binding pose similar to 101F, which may be indicative of cross-reactivity with hMPV F. The data presented provide new concepts in RSV immune recognition and vaccine design, as we describe the novel idea that binding pose may influence mAb cross-reactivity between RSV and hMPV. Characterization of the site IV epitope bound by human antibodies may inform the design of a pan-Pneumovirus vaccine. PMID- 29470534 TI - The effect of isohydric hemodialysis on the binding and removal of uremic retention solutes. AB - BACKGROUND: There is growing evidence that the accumulation of protein- bound uremic retention solutes, such as indoxyl sulfate, p-cresyl sulfate and kynurenic acid, play a role in the accelerated cardiovascular disease seen in patients undergoing chronic hemodialysis. Protein-binding, presumably to albumin, renders these solutes poor-dialyzable. We previously observed that the free fraction of indoxyl sulfate was markedly reduced at the end of hemodialysis. We hypothesized that solute binding might be pH-dependent and attributed the changes in free solute concentration to the higher serum pH observed at the end of standard hemodialysis with dialysis buffer bicarbonate concentration greater than 35 mmol/L. We observed that acidification of uremic plasma to pH 6 in vitro greatly increased the proportion of freeIS. METHODS: We tested our hypothesis by reducing the dialysate bicarbonate buffer concentration to 25 mmol/L for the initial half of the hemodialysis treatment ("isohydric dialysis"). Eight stable hemodialysis patients underwent "isohydric dialysis" for 90 minutes and then were switched to standard buffer (bicarbonate = 37mmol/L). A second dialysis, 2 days later, employed standard buffer throughout. RESULTS: We found a clearcut separation of blood pH and bicarbonate concentrations after 90 minutes of "isohydric dialysis" (pH = 7.37, bicarbonate = 22.4 mmol/L) and standard dialysis (pH = 7.49, bicarbonate = 29.0 mmol/L). Binding affinity varied widely among the 10 uremic retention solutes analyzed. Kynurenic acid (0.05 free), p-cresyl sulfate (0.12 free) and indoxyl sulfate (0.13 free) demonstrated the greatest degree of binding. Three solutes (indoxyl glucuronide, p-cresyl glucuronide, and phenyl glucuronide) were virtually unbound. Analysis of free and bound concentrations of uremic retention solutes confirmed our prediction that binding of solute is affected by pH. However, in a mixed models analysis, we found that the reduction in total uremic solute concentration during dialysis accounted for a greater proportion of the variation in free concentration, presumably an effect of saturation binding to albumin, than did the relatively small change in pH produced by isohydric dialysis. The effect of pH on binding appeared to be restricted to those solutes most highly protein-bound. The solutes most tightly bound exhibited the lowest dialyzer clearances. An increase in dialyzer clearance during isohydric and standard dialyses was statistically significant only for kynurenic acid. CONCLUSION: These findings provide evidence that the binding of uremic retention solutes is influenced by pH. The effect of reducing buffer bicarbonate concentration ("isohydric dialysis:"), though significant, was small but may be taken to suggest that further modification of dialysis technique that would expose blood to a greater decrease in pH would lead to a greater increase the free fraction of solute and enhance the efficacy of hemodialysis in the removal of highly protein-bound uremic retention solutes. PMID- 29470535 TI - Body configuration at first stepping-foot contact predicts backward balance recovery capacity in people with chronic stroke. AB - OBJECTIVE: To determine the predictive value of leg and trunk inclination angles at stepping-foot contact for the capacity to recover from a backward balance perturbation with a single step in people after stroke. METHODS: Twenty-four chronic stroke survivors and 21 healthy controls were included in a cross sectional study. We studied reactive stepping responses by subjecting participants to multidirectional stance perturbations at different intensities on a translating platform. In this paper we focus on backward perturbations. Participants were instructed to recover from the perturbations with maximally one step. A trial was classified as 'success' if balance was restored according to this instruction. We recorded full-body kinematics and computed: 1) body configuration parameters at first stepping-foot contact (leg and trunk inclination angles) and 2) spatiotemporal step parameters (step onset, step length, step duration and step velocity). We identified predictors of balance recovery capacity using a stepwise logistic regression. Perturbation intensity was also included as a predictor. RESULTS: The model with spatiotemporal parameters (perturbation intensity, step length and step duration) could correctly classify 85% of the trials as success or fail (Nagelkerke R2 = 0.61). In the body configuration model (Nagelkerke R2 = 0.71), perturbation intensity and leg and trunk angles correctly classified the outcome of 86% of the recovery attempts. The goodness of fit was significantly higher for the body configuration model compared to the model with spatiotemporal variables (p<0.01). Participant group and stepping leg (paretic or non-paretic) did not significantly improve the explained variance of the final body configuration model. CONCLUSIONS: Body configuration at stepping-foot contact is a valid and clinically feasible indicator of backward fall risk in stroke survivors, given its potential to be derived from a single sagittal screenshot.

AB - PURPOSE: To conduct a retrospective multicenter trial to determine the significance of metastatic site as a predictor of nivolumab efficacy in patients with advanced non-small cell lung cancer. METHODS: This study was conducted across three medical centers in Japan. We retrospectively reviewed all patients who commenced nivolumab treatment at these centers between December 17, 2015 and July 31, 2016. Clinical data were collected, including age, sex, smoking status, Eastern Cooperative Oncology Group performance status, and metastatic site (lymph nodes, liver, brain, bone, lungs [intrapulmonary metastasis], and malignant pleural effusion) at the time of commencing nivolumab treatment. Patients were followed-up until March 31, 2017. RESULTS: Two hundred and one patients were enrolled. The median age at the time of commencing nivolumab treatment was 68 (range, 27-87) years. One hundred and thirty-five patients were male, 157 patients had a history of smoking, 153 patients had a performance status of 0-1, and 42 patients had squamous cell carcinoma. The median progression-free survival of all patients was 2.5 months. In the univariate analysis, a performance status of >=2 (hazard ratio [HR]: 1.89, 95.0% confidence interval [CI]: 1.33-2.69; p < 0.001) and liver (HR: 2.09, 95.0% CI: 1.35-3.25; p < 0.001) and lung (HR: 1.57, 95.0% CI: 1.14-2.16; p < 0.01) metastases correlated with a significantly shorter progression-free survival in nivolumab-treated patients. In the multivariate analysis, a performance status of >=2 (HR: 1.54, 95.0% CI: 1.05-2.25; p < 0.05) and liver (HR: 1.90, 95.0% CI: 1.21-2.98; p < 0.01) and lung (HR: 1.41, 95.0% CI: 1.00-1.99; p < 0.05) metastases were independently correlated with a significantly shorter progression-free survival in nivolumab-treated patients. CONCLUSION: Liver and lung metastases and a poor performance status are independent predictors of nivolumab efficacy in patients with advanced non-small cell lung cancer.

PMID- 29470537 TI - Microsomal prostaglandin E synthase-1 gene deletion impairs neuro-immune circuitry of the cholinergic anti-inflammatory pathway in endotoxaemic mouse spleen. AB - The cholinergic anti-inflammatory pathway (CAP) is an innate neural reflex where parasympathetic and sympathetic nerves work jointly to control inflammation. Activation of CAP by vagus nerve stimulation (VNS) has paved way for novel therapeutic strategies in treating inflammatory diseases. Recently, we discovered that VNS mediated splenic acetylcholine (ACh) release and subsequent immunosuppression in response to LPS associated inflammation is impaired in mice lacking microsomal prostaglandin E synthase-1 (mPGES-1) expression, a key enzyme responsible for prostaglandin E2 synthesis. Here, we have further investigated the consequences of mPGES-1 deficiency on various molecular/cellular events in the spleen which is critical for the optimal functioning of VNS in endotoxaemic mice. First, VNS induced splenic norepinephrine (NE) release in both mPGES-1 (+/+) and (-/-) mice. Compared to mPGES-1 (+/+), immunomodulatory effects of NE on cytokines were strongly compromised in mPGES-1 (-/-) splenocytes. Interestingly, while LPS increased choline acetyltransferase (ChAT) protein level in mPGES-1 (+/+) splenocytes, it failed to exert similar effects in mPGES-1 (-/-) splenocytes despite unaltered beta2 AR protein expression. In addition, nicotine inhibited TNFalpha release by LPS activated mPGES-1 (+/+) splenocytes in vitro. However, such immunosuppressive effects of nicotine were reversed both in mPGES-1 (-/-) mouse splenocytes and human PBMC treated with mPGES-1 inhibitor. In summary, our data implicate PGE2 as an important mediator of ACh synthesis and noradrenergic/cholinergic molecular events in the spleen that constitute a crucial part of the CAP immune regulation. Our results suggest a possible link between cholinergic and PG system of CAP that may be of clinical significance in VNS treatment.

AB - In some insect species, females may base their choice for a suitable mate on male odor. In the red mason bee, Osmia bicornis, female choice is based on a male's odor bouquet as well as its thorax vibrations, and its relatedness to the female, a putative form of optimal outbreeding. Interestingly, O. bicornis can be found as two distinct color morphs in Europe, which are thought to represent subspecies and between which we hypothesize that female discrimination may be particularly marked. Here we investigated (i) if these two colors morphs do indeed represent distinct, reproductively differentiated populations, (ii) how odor bouquets of male O. bicornis vary within and between populations, and (iii) whether variation in male odor correlates with genetic distance, which might represent a cue by which females could optimally outbreed. Using GC and GC-MS analysis of male odors and microsatellite analysis of males and females from 9 populations, we show that, in Denmark, an area of subspecies sympatry, the two color morphs at any one site do not differ, either in odor bouquet or in population genetic differentiation. Yet populations across Europe are distinct in their odor profile as well as being genetically differentiated. Odor differences do not, however, mirror genetic differentiation between populations. We hypothesize that populations from Germany, England and Denmark may be under sexual selection through female choice for local odor profiles, which are not related to color morph though which could ultimately lead to population divergence and speciation. PMID- 29470540 TI - A-674563, a putative AKT1 inhibitor that also suppresses CDK2 activity, inhibits human NSCLC cell growth more effectively than the pan-AKT inhibitor, MK-2206. AB - AKT is a serine-threonine kinase implicated in tumorigenesis as a central regulator of cellular growth, proliferation, survival, and metabolism. Activated AKT is commonly overexpressed in non-small cell lung cancer (NSCLC) and accordingly AKT inhibitors are under clinical investigation for NSCLC treatment. Thus far, the AKT inhibitors being evaluated broadly target all three (1-3) AKT isoforms but recent evidence suggests opposing roles in lung tumorigenesis where loss of Akt1 inhibits while the loss of Akt2 enhances lung tumor development. Based on these findings, we hypothesized that selective inhibition of AKT-1 would be a more effective therapeutic strategy than pan-AKT inhibition for NSCLC treatment. Using six NSCLC cell lines, we found that the AKT-1 inhibitor, A 674563, was significantly more effective at reducing NSCLC cell survival relative to the pan-AKT inhibitor MK-2206. Comparison of the downstream effects of the inhibitors suggests that altered cell cycle progression and off-target CDK2 inhibition are likely vital to the improved efficacy of A-674563 over MK-2206.

PMID- 29470542 TI - Functional fine-tuning between bacterial DNA recombination initiation and quality control systems. AB - Homologous recombination (HR) is crucial for the error-free repair of DNA double strand breaks (DSBs) and the restart of stalled replication. However, imprecise HR can lead to genome instability, highlighting the importance of HR quality control. After DSB formation, HR proceeds via DNA end resection and recombinase loading, whereas helicase-catalyzed disruption of a subset of subsequently formed DNA invasions is thought to be essential for maintaining HR accuracy via inhibiting illegitimate (non-allelic) recombination. Here we show that in vitro characterized mechanistic aberrations of E. coli RecBCD (resection and recombinase loading) RecQ (multifunctional DNA-restructuring helicase) mutant enzyme variants, on one hand, cumulatively deteriorate cell survival under certain conditions of genomic stress. On the other hand, we find that RecBCD and RecQ defects functionally compensate each other in terms of HR accuracy. The abnormally long resection and unproductive recombinase loading activities of a mutant RecBCD complex (harboring the D1080A substitution in RecB) cause enhanced illegitimate recombination. However, this compromised HR-accuracy phenotype is suppressed in double mutant strains harboring mutant RecQ variants with abnormally enhanced helicase and inefficient invasion disruptase activities. These results frame an in vivo context for the interplay of biochemical activities leading to illegitimate recombination, and underscore its long-range genome instability effects manifest in higher eukaryotes. PMID- 29470543 TI - Translational autoregulation of BZW1 and BZW2 expression by modulating the stringency of start codon selection. AB - The efficiency of start codon selection during ribosomal scanning in eukaryotic translation initiation is influenced by the context or flanking nucleotides surrounding the AUG codon. The levels of eukaryotic translation initiation factors 1 (eIF1) and 5 (eIF5) play critical roles in controlling the stringency of translation start site selection. The basic leucine zipper and W2 domain containing proteins 1 and 2 (BZW1 and BZW2), also known as eIF5-mimic proteins, are paralogous human proteins containing C-terminal HEAT domains that resemble the HEAT domain of eIF5. We show that translation of mRNAs encoding BZW1 and BZW2 homologs in fungi, plants and metazoans is initiated by AUG codons in conserved unfavorable initiation contexts. This conservation is reminiscent of the conserved unfavorable initiation context that enables autoregulation of EIF1. We show that overexpression of BZW1 and BZW2 proteins enhances the stringency of start site selection, and that their poor initiation codons confer autoregulation on BZW1 and BZW2 mRNA translation. We also show that overexpression of these two proteins significantly diminishes the effect of overexpressing eIF5 on stringency of start codon selection, suggesting they antagonize this function of eIF5. These results reveal a surprising role for BZW1 and BZW2 in maintaining homeostatic stringency of start codon selection, and taking into account recent biochemical, genetic and structural insights into eukaryotic initiation, suggest a model for BZW1 and BZW2 function. PMID- 29470544 TI - Validation of the What Matters Index: A brief, patient-reported index that guides care for chronic conditions and can substitute for computer-generated risk models. AB - INTRODUCTION: Current health care delivery relies on complex, computer-generated risk models constructed from insurance claims and medical record data. However, these models produce inaccurate predictions of risk levels for individual patients, do not explicitly guide care, and undermine health management investments in many patients at lesser risk. Therefore, this study prospectively validates a concise patient-reported risk assessment that addresses these inadequacies of computer-generated risk models. METHODS: Five measures with well documented impacts on the use of health services are summed to create a "What Matters Index." These measures are: 1) insufficient confidence to self-manage health problems, 2) pain, 3) bothersome emotions, 4) polypharmacy, and 5) adverse medication effects. We compare the sensitivity and predictive values of this index with two representative risk models in a population of 8619 Medicaid recipients. RESULTS: The patient-reported "What Matters Index" and the conventional risk models are found to exhibit similar sensitivities and predictive values for subsequent hospital or emergency room use. The "What Matters Index" is also reliable: akin to its performance during development, for patients with index scores of 1, 2, and >=3, the odds ratios (with 95% confidence intervals) for subsequent hospitalization within 1 year, relative to patients with a score of 0, are 1.3 (1.1-1.6), 2.0 (1.6-2.4), and 3.4 (2.9-4.0), respectively; for emergency room use, the corresponding odds ratios are 1.3 (1.1 1.4), 1.9 (1.6-2.1), and 2.9 (2.6-3.3). Similar findings were replicated among smaller populations of 1061 mostly older patients from nine private practices and 4428 Medicaid patients without chronic conditions. SUMMARY: In contrast to complex computer-generated risk models, the brief patient-reported "What Matters Index" immediately and unambiguously identifies fundamental, remediable needs for each patient and more sensibly directs the delivery of services to patient categories based on their risk for subsequent costly care. PMID- 29470545 TI - Private healthcare provider experiences with social health insurance schemes: Findings from a qualitative study in Ghana and Kenya. AB - BACKGROUND: Incorporating private healthcare providers into social health insurance schemes is an important means towards achieving universal health coverage in low and middle income countries. However, little research has been conducted about why private providers choose to participate in social health insurance systems in such contexts, or their experiences with these systems. We explored private providers' perceptions of and experiences with participation in two different social health insurance schemes in Sub-Saharan Africa-the National Health Insurance Scheme (NHIS) in Ghana and the National Hospital Insurance Fund (NHIF) in Kenya. METHODS: In-depth interviews were held with providers working at 79 facilities of varying sizes in three regions of Kenya (N = 52) and three regions of Ghana (N = 27). Most providers were members of a social franchise network. Interviews covered providers' reasons for (non) enrollment in the health insurance system, their experiences with the accreditation process, and benefits and challenges with the system. Interviews were coded in Atlas.ti using an open coding approach and analyzed thematically. RESULTS: Most providers in Ghana were NHIS-accredited and perceived accreditation to be essential to their businesses, despite challenges they encountered due to long delays in claims reimbursement. In Kenya, fewer than half of providers were NHIF-accredited and several said that their clientele were not NHIF enrolled. Understanding of how the NHIF functioned was generally low. The lengthy and cumbersome accreditation process also emerged as a major barrier to providers' participation in the NHIF in Kenya, but the NHIS accreditation process was not a major concern for providers in Ghana. CONCLUSIONS: In expanding social health insurance, coordinated efforts are needed to increase coverage rates among underserved populations while also accrediting the private providers who serve those populations. Market pressure was a key force driving providers to gain and maintain accreditation in both countries. Developing mechanisms to engage private providers as stakeholders in social health insurance schemes is important to incentivizing their participation and addressing their concerns. PMID- 29470546 TI - Computer simulations reveal changes in the conformational space of the transcriptional regulator MosR upon the formation of a disulphide bond and in the collective motions that regulate its DNA-binding affinity. AB - M. tuberculosis oxidation sense Regulator (MosR) is a transcriptional regulator from Mycobacterium tuberculosis. It senses the environment oxidation and regulates the expression of a secreted oxidoreductase, thus defending the bacilli against oxidative stress from the phagosome. While most of the members of the Multiple antibiotics resistance Regulator (MarR) family are ligand-responsive, MosR may dissociate from its DNA site upon formation of an intrachain disulphide bond. However, the structure of MosR in its oxidized state is not known, and it is not clear how the formation of this disulphide bond would lead to the conformational changes required for dissociation of the DNA. Nonetheless, MosR presents two crystallographically resolved conformations in its reduced state: bound and unbound to DNA. We managed to simulate MosR unbound to the DNA, both in the presence and in the absence of the disulphide bond. Our results indicate that this disulphide bond precludes the N-terminal residues from adopting a conformation that stands in-between the helix alpha1 and the DNA binding domain (DBD) from the other chain. Once this conformation is achieved in the reduced state, this DBD detaches from the dimerization domain and becomes more flexible, being able to perform motions with higher amplitude and higher degree of collectivity. Only then, MosR may achieve a conformation where its recognition helices fit into the major grooves of its DNA site. The analysis of the collective motions performed by MosR, during the different situations sampled by the molecular dynamics (MDs), was only possible by the method of filtering harmonic modes with specific frequencies. The frequency of the collective motions performed by the DBD of MosR in the reduced state to achieve a DNA-binding conformation is in the range of 20 to 50 MHz, but it may be associated to more sporadic events since it requires the combination of a suitable conformation of the N-terminal residues. PMID- 29470547 TI - The characteristics of residents with unawareness of hepatitis C virus infection in community. AB - BACKGROUND: Control of hepatitis C virus infection (HCV) is an increasingly important issue. Enhancing screening coverage is necessary to discover more HCV infected subjects in community. However, a substantial population is unaware of HCV infection that needs more attention. AIM: The aims of this study were to evaluate the status of HCV infected residents in remote villages, to compare characteristics between already known and unaware HCV infection subjects, and to analyze the disease insights. PATIENTS AND METHODS: Screening intervention for liver diseases was conducted in remote villages of Tainan City of southern Taiwan from August 2014 to July 2016. Items of screening examinations included questionnaire, blood sampling for liver tests and viral hepatitis markers (hepatitis B surface antigen and anti-HCV antibody), abdominal sonography survey, and liver stiffness measurement by transient elastography. Quantitation of HCV RNA was measured for residents with positive anti-HCV antibody. RESULTS: A total of 194 (13.5%) out of 1439 participants showed positive for anti-HCV antibody. HCV viremia was detected in 119 (61.3%) residents. Previously unaware HCV infection by questionnaire record was present in 68 (35.1%) of ant-HCV positive residents. By multivariate logistic analysis, unaware HCV infected residents exhibited significantly mild liver fibrosis (OR 0.876, 95% CI 0.782~0.981, p = 0.022), more prevalent of heart diseases (OR 6.082, 95% CI 1.963~18.839, p = 0.002), and less cluster of family history of liver diseases (OR 0.291, 95% CI 0.113~0.750, p = 0.011) when comparing with already known HCV infected residents. Among the 126 already know HCV infected residents, only 59 (46.8%) received antiviral treatment or regular follow-up. No concept or no willing to receive medical care was observed in 44 (34.9%) residents. CONCLUSION: In HCV endemic villages of Taiwan, residents with unaware HCV infection comprised about one third of HCV infected residents and exhibited obscure characteristics to identify. Less than half of already known HCV infected residents received adequate medical care. To eliminate HCV infection, vigorous efforts on enhancing screening coverage, educating update knowledge of liver diseases, and linking to medical care are urgently needed. PMID- 29470548 TI - Using aided cortical assessment as an objective tool to evaluate cochlear implant fitting in users with single-sided deafness. AB - OBJECTIVES: To assess the use of cortical auditory evoked potentials (CAEPs) to verify, and if necessary, optimize the cochlear implant (CI) fitting of adult CI users with postlingual single-sided deafness (SSD). METHODS: Sound field cortical responses to the speech tokens /m/, /g/, /t/, and /s/ were recorded from input to the CI while the normal hearing ear was masked. Responses were evaluated by visual inspection and classified as presence or absence of the CAEPs components P1, N1, P2. In case of an absence fitting was adjusted accordingly. After fitting, subjects were asked to use their new setting for 2-3 weeks for acclimatization purposes and then return for retesting. At retesting, new CAEP recordings were performed to objectively ensure that the new fitting maps effectively activated the auditory cortex. RESULTS: In 14/19 subjects, as per visual inspection, clear CAEPs were recorded by each speech token and were, therefore, not refit. In the other 5 subjects, CAEPs could not be evoked for at least one speech token. The fitting maps in these subjects were adjusted until clear CAEPs were evoked for all 4 speech tokens. CONCLUSIONS: CAEP can be used to quickly and objectively verify the suitability of CI fitting in experienced adult CI users with SSD. If used in the early post-implantation stage, this method could help CI users derive greater benefit for CI use and, therefore, be more committed to auditory training.

Adenosine to-inosine (A-to-I) editing is the predominant type of RNA editing in mammals and it is catalyzed by the adenosine deaminases acting on RNA (ADARs) family. Here, we used a largescale computational analysis of transcriptomic data from brain, heart, colon, lung, spleen, kidney, testes, skeletal muscle and liver, from three adult animals in order to identify RNA editing sites in bovine. We developed a computational pipeline and used a rigorous strategy to identify novel editing sites from RNA-Seq data in the absence of corresponding DNA sequence information. Our methods take into account sequencing errors, mapping bias, as well as biological replication to reduce the probability of obtaining a false-positive result. We conducted a detailed characterization of sequence and structural features related to novel candidate sites and found 1,600 novel canonical A-to-I editing sites in the nine bovine tissues analyzed. Results show that these sites 1) occur frequently in clusters and short interspersed nuclear elements (SINE) repeats, 2) have a preference for guanines depletion/enrichment in the flanking 5'/3' nucleotide, 3) occur less often in coding sequences than other regions of the genome, and 4) have low evolutionary conservation. Further, we found that a positive correlation exists between expression of ADAR family members and tissue specific RNA editing. Most of the genes with predicted A-to-I editing in each tissue were significantly enriched in biological terms relevant to the function of the corresponding tissue. Lastly, the results highlight the importance of the RNA editome in nervous system regulation. The present study extends the list of RNA editing sites in bovine and provides pipelines that may be used to investigate the editome in other organisms. PMID- 29470550 TI - The pregnane X receptor (PXR) and the nuclear receptor corepressor 2 (NCoR2) modulate cell growth in head and neck squamous cell carcinoma. AB - Head and neck squamous cell carcinoma (HNSCC) is the sixth most frequent cancer worldwide. The pregnane X receptor (PXR) is a nuclear receptor regulating several target genes associated with cancer malignancy. We here demonstrated a significant effect of PXR on HNSCC cell growth, as evidenced in PXR knock-down experiments. PXR transcriptional activity is more importantly regulated by the presence of coactivators and corepressors than by PXR protein expression. To date, there is scarce information on the regulation of PXR in HNSCC and on its role in the pathogenesis of this disease. Coactivator and corepressor expression was screened through qRT-PCR in 8 HNSCC cell lines and correlated to PXR activity, determined by using a reporter gene assay. All cell lines considerably expressed all the cofactors assessed. PXR activity negatively correlated with nuclear receptor corepressor 2 (NCoR2) expression, indicating a major role of this corepressor in PXR modulation and suggesting its potential as a surrogate for PXR activity in HNSCC. To test the association of NCoR2 with the malignant phenotype, a subset of three cell lines was transfected with an over-expression plasmid for this corepressor. Subsequently, cell growth and chemoresistance assays were performed. To elucidate the mechanisms underlying NCoR2 effects on cell growth, caspase 3/7 activity and protein levels of cleaved caspase 3 and PARP were evaluated. In HNO97 cells, NCoR2 over-expression decreased cell growth, chemoresistance and increased cleaved caspase 3 levels, caspase activity and cleaved PARP levels. On the contrary, in HNO124 and HNO210 cells, NCoR2 over expression increased cell growth, drug resistance and decreased cleaved caspase 3 levels, caspase activity and cleaved PARP levels. In conclusion, we demonstrated a role of PXR and NCoR2 in the modulation of cell growth in HNSCC. This may contribute to a better understanding of the highly variable HNSCC therapeutic response. PMID- 29470551 TI - Tph2-/- female mice restore socio-sexual recognition through upregulating ERalpha and OTR genes in the amygdala. AB - The central 5-hydroxytryptamine system impairs sociosexual behaviors and olfaction preferences in sexually naive mice. However, it remains unknown whether reproductive experiences impart an effect on the sexual olfactory preferences of female mice lacking central serotonin. Here, we aimed at examining such effects and the underlying mechanisms using Tph2 knockout female mice. Sexually naive Tph2-/- female mice failed to recognize olfactory cues regarding sex, genetic relatedness, and social hierarchy despite exhibiting normal olfactory discrimination. However, reproduction-experienced Tph2-/- female mice recovered sexual olfactory preferences, as did sexually naive Tph2+/+ females. Meanwhile, both the estrogen receptor alpha and oxytocin receptor in the amygdala of reproduction-experienced Tph2-/- females presented upregulated expression at the mRNA level and an upward tendency at the protein level vs. sexually naive Tph2-/- females. Intracerebroventricular administration of a combination of estrogen receptor alpha and oxytocin receptor agonists, but not either agent alone, could restore the sexual olfactory preferences of sexually naive Tph2-/- female mice to some degree. We speculate that estrogen receptor alpha and oxytocin receptor activation in the amygdala after reproductive experiences restores sexual olfactory recognition in Tph2-/- female mice.

PMID- 29470552 TI - Increased HIV-1 transcriptional activity and infectious burden in peripheral blood and gut-associated CD4+ T cells expressing CD30. AB - HIV-1-infected cells persist indefinitely despite the use of combination antiretroviral therapy (ART), and novel therapeutic strategies to target and purge residual infected cells in individuals on ART are urgently needed. Here, we demonstrate that CD4+ T cell-associated HIV-1 RNA is often highly enriched in cells expressing CD30, and that cells expressing this marker considerably contribute to the total pool of transcriptionally active CD4+ lymphocytes in individuals on suppressive ART. Using in situ RNA hybridization studies, we show co-localization of CD30 with HIV-1 transcriptional activity in gut-associated lymphoid tissues. We also demonstrate that ex vivo treatment with brentuximab vedotin, an antibody-drug conjugate (ADC) that targets CD30, significantly reduces the total amount of HIV-1 DNA in peripheral blood mononuclear cells obtained from infected, ART-suppressed individuals. Finally, we observed that an HIV-1-infected individual, who received repeated brentuximab vedotin infusions for lymphoma, had no detectable virus in peripheral blood mononuclear cells. Overall, CD30 may be a marker of residual, transcriptionally active HIV-1 infected cells in the setting of suppressive ART. Given that CD30 is only expressed on a small number of total mononuclear cells, it is a potential therapeutic target of persistent HIV-1 infection. PMID- 29470554 TI - Likelihood ratios of quantitative laboratory results in medical diagnosis: The application of Bezier curves in ROC analysis. AB - Receiver operating characteristic (ROC) analysis is widely used to describe the discriminatory power of a diagnostic test to differentiate between populations having or not having a specific disease, using a dichotomous threshold. In this way, positive and negative likelihood ratios (LR+ and LR-) can be calculated to be used in Bayes' way of estimating disease probabilities. Similarly, LRs can be calculated for certain ranges of test results. However, since many diagnostic tests are of quantitative nature, it would be desirable to estimate LRs for each quantitative result. These LRs are equal to the slope of the tangent to the ROC curve at the corresponding point. Since the exact distribution of test results in diseased and non-diseased people is often not known, the calculation of such LRs for quantitative test results is not straightforward. Here, a simple distribution independent method is described to reach this goal using Bezier curves that are defined by tangents to a curve. The use of such a method would help in standardizing quantitative test results, which are not always comparable between different test providers, by reporting them as LRs for a specific diagnosis, in addition to, or instead of, quantities such as mg/L or nmol/L, or even indices or units. PMID- 29470555 TI - Bernese motive and goal inventory in exercise and sport: Validation of an updated version of the questionnaire. AB - Target group-specific intervention strategies are often called for in order to effectively promote exercise and sport. Currently, motives and goals are rarely included systematically in the design of interventions, despite the key role they play in well-being and adherence to exercise. The Bernese motive and goal inventory (BMZI) allows an individual diagnosis of motives and goals in exercise and sport in people in middle adulthood. The purpose of the present study was to elaborate on the original BMZI and to modify the questionnaire in order to improve its psychometric properties. The study is based on data from two samples (sample A: 448 employees of companies and authorities; sample B: 853 patients of a medical rehabilitation programme). We applied confirmatory factor analysis and exploratory structural equation modelling. Overall, both the original and the updated BMZI had an acceptable to good validity and a good reliability. However, the revised questionnaire had slightly better reliability. The updated BMZI consists of 23 items and covers the following motives and goals: Body/Appearance, Contact, Competition/Performance, Aesthetics, Distraction/Catharsis, Fitness and Health. It is recommended as an economical inventory for the individual diagnosis of important psychological conditions for exercise and sport. PMID- 29470557 TI - Design of a 3D-printed, open-source wrist-driven orthosis for individuals with spinal cord injury. AB - Assistive technology, such as wrist-driven orthoses (WDOs), can be used by individuals with spinal cord injury to improve hand function. A lack of innovation and challenges in obtaining WDOs have limited their use. These orthoses can be heavy and uncomfortable for users and also time-consuming for orthotists to fabricate. The goal of this research was to design a WDO with user (N = 3) and orthotist (N = 6) feedback to improve the accessibility, customizability, and function of WDOs by harnessing advancements in 3D-printing. The 3D-printed WDO reduced hands-on assembly time to approximately 1.5 hours and the material costs to $15 compared to current fabrication methods. Varying improvements in users' hand function were observed during functional tests, such as the Jebsen Taylor Hand Function Test. For example, one participant's ability on the small object task improved by 29 seconds with the WDO, while another participant took 25 seconds longer to complete this task with the WDO. Two users had a significant increase in grasp strength with the WDO (13-122% increase), while the other participant was able to perform a pinching grasp for the first time. The WDO designs are available open-source to increase accessibility and encourage future innovation. PMID- 29470556 TI - No evidence for association between APOL1 kidney disease risk alleles and Human African Trypanosomiasis in two Ugandan populations. AB - BACKGROUND: Human African trypanosomiasis (HAT) manifests as an acute form caused by Trypanosoma brucei rhodesiense (Tbr) and a chronic form caused by Trypanosoma brucei gambiense (Tbg). Previous studies have suggested a host genetic role in infection outcomes, particularly for APOL1. We have undertaken candidate gene association studies (CGAS) in a Ugandan Tbr and a Tbg HAT endemic area, to determine whether polymorphisms in IL10, IL8, IL4, HLAG, TNFA, TNX4LB, IL6, IFNG, MIF, APOL1, HLAA, IL1B, IL4R, IL12B, IL12R, HP, HPR, and CFH have a role in HAT. METHODOLOGY AND RESULTS: We included 238 and 202 participants from the Busoga Tbr and Northwest Uganda Tbg endemic areas respectively. Single Nucleotide Polymorphism (SNP) genotype data were analysed in the CGAS. The study was powered to find odds ratios > 2 but association testing of the SNPs with HAT yielded no positive associations i.e. none significant after correction for multiple testing. However there was strong evidence for no association with Tbr HAT and APOL1 G2 of the size previously reported in the Kabermaido district of Uganda. CONCLUSIONS/SIGNIFICANCE: A recent study in the Soroti and Kaberamaido focus in Central Uganda found that the APOL1 G2 allele was strongly associated with protection against Tbr HAT (odds ratio = 0.2, 95% CI: 0.07 to 0.48, p = 0.0001). However, in our study no effect of G2 on Tbr HAT was found, despite being well powered to find a similar sized effect (OR = 0.9281, 95% CI: 0.482 to 1.788, p = 0.8035). It is possible that the G2 allele is protective from Tbr in the Soroti/Kabermaido focus but not in the Iganga district of Busoga, which differ in ethnicity and infection history. Mechanisms underlying HAT infection outcome and virulence are complex and might differ between populations, and likely involve several host, parasite or even environmental factors. PMID- 29470558 TI - HIC1 links retinoic acid signalling to group 3 innate lymphoid cell-dependent regulation of intestinal immunity and homeostasis. AB - The intestinal immune system must be able to respond to a wide variety of infectious organisms while maintaining tolerance to non-pathogenic microbes and food antigens. The Vitamin A metabolite all-trans-retinoic acid (atRA) has been implicated in the regulation of this balance, partially by regulating innate lymphoid cell (ILC) responses in the intestine. However, the molecular mechanisms of atRA-dependent intestinal immunity and homeostasis remain elusive. Here we define a role for the transcriptional repressor Hypermethylated in cancer 1 (HIC1, ZBTB29) in the regulation of ILC responses in the intestine. Intestinal ILCs express HIC1 in a vitamin A-dependent manner. In the absence of HIC1, group 3 ILCs (ILC3s) that produce IL-22 are lost, resulting in increased susceptibility to infection with the bacterial pathogen Citrobacter rodentium. Thus, atRA dependent expression of HIC1 in ILC3s regulates intestinal homeostasis and protective immunity.

PMID- 29470561 TI - Safety and Efficacy of Cosmetic Augmentation of the Nasal Tip and Nasal Dorsum With Expanded Polytetrafluoroethylene: A Randomized Clinical Trial. AB - Importance: Expanded polytetrafluoroethylene (ePTFE) is a widely used alloplast, but studies of augmentation of the nasal tip and nasal dorsum with ePTFE are lacking. Objective: To investigate whether attaching the conchal cartilage as shield grafts at the distal end of the graft can prevent extrusion and whether the use of ePTFE in the nasal tip can achieve a stable aesthetic outcome. Design, Setting, and Participants: A randomized clinical trial was performed from April 1, 2006, to October 31, 2008. Follow-up was completed in 2012 and 2017. The study was conducted at the Department of Plastic and Reconstructive Surgery, Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai, China. One hundred fifty patients seeking rhinoplasty were recruited, and 129 were eligible for inclusion in the study. All the recruited patients were intent-to-treat populations who were randomized into 2 groups: an ePTFE-only group and an ePTFE with conchal cartilage group. Interventions: Expanded PTFE was used for augmentation of the nasal tip and nasal dorsum in both groups. Conchal cartilage was placed above the distal end in the ePTFE with conchal cartilage group. Main Outcomes and Measures: Preoperative and postoperative standard photographs were obtained. Postoperative satisfaction and complications were evaluated. Results: Of the 129 patients (mean age [range], 28 years [21-45 years]; 6 male and 123 female) eligible for inclusion in this study, 76 (mean age [range], 31 years [22-45 years]; 4 male and 72 female) were available for follow up (mean [range], 106.9 months [100-131 months]) through 2017, including 39 in the ePTFE-only group and 37 in the ePTFE with conchal cartilage group. Infection occurred in 2 patients (5%) in the ePTFE-only group vs 1 patient (3%) in the ePTFE with conchal cartilage group (infection rate [OR, 1.946; 95% CI, 0.169 22.413; P > .99]). Soft-tissue reaction occurred in 0 patients in the ePTFE-only group vs 1 patient (3%) in the ePTFE with conchal cartilage group (soft-tissue reaction rate [OR, 0.000; 95% CI, 0.000-8.538; P = .49]). Irregularity occurred in 0 patients in the ePTFE-only group vs 3 patients (8%) in the ePTFE with conchal cartilage group (irregularity rate [OR, 0.000; 95% CI, 0.000-1.066; P = .11]). Extrusion occurred in neither of the 2 groups. Conclusions and Relevance: A new technique using ePTFE alone for augmentation of the nasal tip and nasal dorsum achieved safe, attractive, and acceptable outcomes in nasal contouring and patient satisfaction. The use of conchal cartilage as a shield in the nasal tip is not necessary. Level of Evidence: 1. Trial Registration: Chinese Clinical Trial Registry identifier: ChiCTR-INR-17011101. PMID- 29470562 TI - Association of Nasal Tip Rotation Outcome Estimation With the New Domes Technique in Primary Rhinoplasty. AB - Importance: The postoperative changes in the rotation of the nasal tip in rhinoplasty must be estimated for the surgical planning. Objective: To determine whether the outcome in the rotation angle of the nasal tip can be estimated in patients undergoing primary rhinoplasty with the new domes technique. Design, Setting, and Participants: This retrospective analytic cohort study included 323 patients undergoing primary rhinoplasty with the new domes technique in a private clinic in Bogota, Colombia, by a single surgeon from January 1, 2011, through January 31, 2016. Patients undergoing secondary rhinoplasty and those with less than 6 months of follow-up were excluded. Exposures: Primary rhinoplasty using the new domes technique. Main Outcomes and Measures: Measurement of the rotation angle of the nasal tip before and 1 week and 6 months after surgery. The main variable taken into consideration was the measurement, in millimeters, of the lateralized nasal domes. Results: A total of 323 patients (288 women [89.2%] and 35 men [10.8%]; mean age, 27.8 years; age range, 13-70 years) were included in the study. The mean (SD) preoperative nasolabial angle was 92.7 degrees (4.4 degrees ; range, 77 degrees -107 degrees ); at 1 postoperative week, 105.5 degrees (4.9 degrees ; range, 92 degrees -120 degrees ); and at 6 postoperative months, 102.1 degrees (4.6 degrees ; range, 90 degrees -115 degrees ). The mean (SD) increase of the rotation that was achieved per lateralized millimeter was 3.6 degrees (2.0 degrees ). The mean (SD) rotation angle at 6 months decreased to 3.4 degrees (2.4 degrees ). Conclusions and Relevance: The new domes technique was reliable and reproducible in most patients. Despite the unpredictable inflammatory changes, the exact lateralization in millimeters with the new domes technique allowed precise estimation of the long-term outcome of the rotation of the nasal tip, enabling the surgeon to determine from the preoperative plan the definitive rotation angle of the nose.

AB - Importance: Current recommendations envisage early surgical exploration for complete facial nerve paralysis associated with temporal bone fracture and unfavorable electrophysiologic features (response to electroneuronography, <5%). However, the evidence base for such a practice is weak, with the potential for spontaneous improvement being unknown, and the expected results from alternative nonsurgical treatment also undefined. Objective: To document the results of nonsurgical treatment for posttraumatic complete facial paralysis with undisplaced temporal bone fracture and unfavorable electrophysiologic features. Design, Setting, and Participants: Prospective cohort study recruiting from April 2010 to April 2013 at a tertiary care university hospital. Follow-up continued until 9 months or until complete recovery if earlier. Study group included 28 patients with head injury-associated complete unilateral facial nerve paralysis with unfavorable results of electroneuronography (<5% response) with or without undisplaced temporal bone fracture. Undisplaced temporal bone fractures were documented in 26 patients (24 longitudinal fractures and 2 transverse fractures). Interventions: Patients received prednisolone, 1 mg/kg, for 3 weeks combined with clinical monitoring every 2 weeks and electromyography monitoring every 4 weeks. As per study protocol, surgical exploration was limited to patients demonstrating motor end plate degeneration on results of electromyography, or having no improvement until 18 weeks. Main Outcomes and Measures: Facial nerve function was evaluated by the House-Brackmann grading system; Forehead, Eye, Mouth, and Associated defect grading system; and the modified Adour system. Observations were completed at 40 weeks. Results: Among the 28 patients in the study (3 women and 25 men; mean [SD] age, 32.2 [8.7] years), facial nerve recovery with conservative treatment alone was noted in all patients. No recovery was seen in any patient at the initial 4-week review. The first signs of clinical recovery were noted in 4 patients by 8 weeks, in 27 patients by 12 weeks, and in all patients by 20 weeks. No patient required surgical exploration. At 40 weeks, 27 patients recovered to House-Brackmann grade I/II and 1 patient to grade III. All 24 patients with longitudinal fractures had grade I/II recovery. Conclusions and Relevance: For undisplaced temporal bone fractures, nonsurgical treatment leads to near-universal recovery to House-Brackmann grade I/II and is superior to reported surgical results. Recovery is delayed and usually first manifests at 8 to 12 weeks after the fracture. In the current era of high-resolution computed tomography, surgical exploration should not be first-line treatment for undisplaced longitudingal temporal bone fractures associated with complete facial nerve paralysis and unfavorable electrophysiologic features. PMID- 29470565 TI - Sociodemographic, Medical, and Psychosocial Factors Associated With Supportive Care Needs in Adults Diagnosed With Uveal Melanoma. AB - Importance: Understanding supportive care needs in patients with cancer is important for developing approaches that enhance quality of life and promote satisfaction with care. Objective: To characterize the nature and frequency of sociodemographic, medical, and psychosocial factors associated with unmet needs in patients with uveal melanoma 1 week and 3 months after diagnosis. Design, Setting, and Participants: This 3-month, prospective, longitudinal survey study was conducted at a university-based ophthalmology practice from June 1, 2007, to July 1, 2011. Data were analyzed in April 2017. Consecutive patients (n = 429) scheduled for diagnostic evaluation for an intraocular abnormality were assessed for eligibility. Participants were ineligible (n = 25) if they were younger than 18 years, had previous advanced cancer, or evidenced cognitive impairment. Of the patients who provided informed consent (n = 306), those subsequently diagnosed with uveal melanoma by an ophthalmologist (n = 107) were included in the analysis. Main Outcomes and Measures: Unmet needs (ie, desire for help in psychological, physical, health information, communication, or social domains) were assessed using the Cancer Needs Questionnaire. Multivariable regression analyses determined factors associated with unmet need severity across 3 months. Results: One hundred seven patients (58 [54%] men; mean [SD] age, 59.0 [12.8] years) completed the baseline assessment. At 1 week after diagnosis, nearly all patients (85 of 86 [99%]) expressed at least 1 unmet need, as did 68 of 79 (86%) 3 months later. The most frequently endorsed needs were in the health information and psychological domains. Patients' unmet needs declined significantly over 3 months (mean [SD] change, -10.0 [14.4]; 95% CI, -6.4 to -13.6; t = -5.6). Sociodemographic and medical characteristics were unrelated to unmet need severity. However, higher prediagnosis instrumental social support (b = -0.2; 95% CI, -0.3 to -0.1; z = -2.8) and lower neuroticism (b = 0.3; 95% CI, 0.1-0.5; z = 2.9) predicted lower unmet need severity 1 week after diagnosis. Having a smaller social network predicted lower unmet need severity 3 months after diagnosis (b < 0.1; 95% CI, <0.1 to <0.1; z = 2.4) as well as a decline in needs from diagnosis to 3 months later (b < 0.1; 95% CI, <0.1 to <0.1; z = 2.3). Conclusions and Relevance: Within 1 week after diagnosis and 3 months later, most patients with uveal melanoma cited important health information and psychological needs. These findings suggest that prior to or at diagnosis, the severity of such needs and psychosocial factors that may be associated can be identified for proactive supportive intervention. PMID- 29470566 TI - Comparison of Subjective Assessment and Precise Quantitative Assessment of Lesion Distribution in Diabetic Retinopathy. AB - Importance: Predominantly peripheral disease in eyes with nonproliferative diabetic retinopathy (DR) is suggested as a potential strong risk factor for progression to proliferative disease. However, the reliability and optimal method for the assessment of lesion distribution are still uncertain. Objective: To compare agreement between subjective assessment and precise quantification of lesion burden in ultrawidefield (UWF) images of eyes with DR. Design, Setting, and Participants: This multisite cross-sectional study examines UWF pseudocolor images acquired from DR screening clinic patients from December 20, 2014, through August 1, 2014. Of 104 cases, 161 eyes with DR were included. Data analysis was conducted from June 1, 2016, through December 1, 2016 at the Doheny Image Reading Center. Main Outcomes and Measures: Distribution of DR lesions in eyes was assessed subjectively and quantitatively, and eyes were classified as having predominantly central lesions (PCLs) or predominantly peripheral lesions (PPLs). The frequency and surface area (SA) of each lesion type were quantified. Intergrader and subjective vs quantitative classification were compared for level of agreement. Several methods of determining PPL distribution were also compared. Results: On subjective frequency-based evaluation by graders, 133 eyes were classified as having PCL, and 28 eyes as having PPL. On exact quantification of lesion SA, 121 eyes were classified as PCL, and 40 eyes as having PPL. On SA based quantification, 134 eyes were classified as having PCL, and 27 eyes as having PPL. There was a significant difference between qualitative and quantitative classification of DR lesion distribution for both frequency-based (mean difference [SD]: PCL, 6 [2]; PPL, 13 [6]; P < .001) and SA-based (mean difference [SD]: PCL, 6 [1]; PPL, 20 [7]; P < .001) methods. Both intergrader reproducibility and subjective vs quantitative agreement were higher with frequency-based classification. Conclusions and Relevance: Subjective assessment of PPL DR lesions on UWF images differed in some cases from precise quantitative assessments, particularly when considering the area of lesions. These findings highlight the benefit of objective quantitative approaches to DR assessment, which may facilitate the development of a more precise DR scoring system.

AB - Importance: Multiparametric magnetic resonance imaging (MRI) in conjunction with MRI-transrectal ultrasound (TRUS) fusion-guided biopsies have improved the detection of prostate cancer. It is unclear whether MRI itself adds additional value to multivariable prediction models based on clinical parameters. Objective: To determine whether an MRI-based prediction model can reduce unnecessary biopsies in patients with suspected prostate cancer. Design, Setting, and Participants: Patients underwent MRI, MRI-TRUS fusion-guided biopsy, and 12-core systematic biopsy in 1 session. The development cohort used to derive the prediction model consisted of 400 patients from 1 institution enrolled between May 14, 2015, and August 31, 2016, and the validation cohort included 251 patients from 2 independent institutions who underwent biopsies between April 1, 2013, and June 30, 2016, at 1 institution and between July 1, 2015, and October 31, 2016, at the other institution. The MRI model included MRI-derived parameters in addition to clinical variables. Area under the curve of receiver operating characteristic curves and decision curve analysis were performed. Main Outcomes and Measures: Risk of clinically significant prostate cancer on biopsy, defined as a Gleason score of 3 + 4 or higher in at least 1 biopsy core. Results: Overall, 193 (48.3%) of the 400 patients in the development cohort (mean [SD] age at biopsy, 64.3 [7.1] years) and 96 (38.2%) of the 251 patients in the validation cohort (mean [SD] age at biopsy, 64.9 [7.2] years) had clinically significant prostate cancer, defined as a Gleason score greater than or equal to 3 + 4. By applying the model to the external validation cohort, the area under the curve increased from 64% to 84% compared with the baseline model (P < .001). At a risk threshold of 20%, the MRI model had a lower false-positive rate than the baseline model (46% [95% CI, 32%-66%] vs 92% [95% CI, 70%-100%]), with only a small reduction in the true-positive rate (89% [95% CI, 85%-96%] vs 99% [95% CI, 89% 100%]). Eighteen of 100 fewer biopsies could have been performed, with no increase in the number of patients with missed clinically significant prostate cancers. Conclusions and Relevance: The inclusion of MRI-derived parameters in a risk model could reduce the number of unnecessary biopsies while maintaining a high rate of diagnosis of clinically significant prostate cancers.

PMID- 29470571 TI - Prevalence of Myelin Oligodendrocyte Glycoprotein and Aquaporin-4-IgG in Patients in the Optic Neuritis Treatment Trial. AB - Importance: Autoantibodies to aquaporin-4 (AQP4) and myelin oligodendrocyte glycoprotein (MOG) are recently established biomarkers of autoimmune optic neuritis whose frequency and accompanying phenotype, especially for MOG-IgG, are still being characterized. The Optic Neuritis Treatment Trial (ONTT) was a well known randomized clinical trial in optic neuritis; therefore, knowledge of the serostatus and accompanying phenotype of these patients would be useful to determine the frequency of these antibodies in patients presenting with typical monocular optic neuritis and their outcomes. Objectives: To determine the AQP4 IgG and MOG-IgG serostatus of patients within the ONTT and describe the clinical features of seropositive patients. Design, Setting, and Participants: In this follow-up study of the randomized clinical trial, ONTT, conducted between July 1, 1988, and June 30, 1991, analysis of serum for AQP4-IgG and MOG-IgG was performed from January 1 to April 30, 2017. A total of 177 patients from the ONTT with acute optic neuritis and serum available for analysis were enrolled from 13 academic referral centers. Interventions: Analysis of serum for AQP4-IgG and MOG IgG was performed at Mayo Clinic Neuroimmunology Laboratory in 2017 with a flow cytometry, live cell, AQP4- and MOG-transfected cell-based assay. Main Outcomes and Measures: Aquaporin-4-IgG and MOG-IgG serostatus. Results: Of the 177 patients in the study (135 women and 42 men; mean [SD] age, 32.8 [6.9] years), 3 were positive for MOG-IgG (1.7%) and none were positive for AQP4-IgG. All 3 patients positive for MOG-IgG had disc edema at presentation. Two patients later had a single episode of recurrent optic neuritis. All 3 patients had complete recovery of visual acuity, and none were corticosteroid dependent, although peripheral visual field loss persisted in 1 patient. None of the 3 patients positive for MOG-IgG had demyelinating lesions on magnetic resonance imaging scans, and none had developed multiple sclerosis at the 15-year follow-up. Conclusions and Relevance: Frequency of MOG-IgG was rare in the ONTT, and AQP4 IgG was not found in patients in the ONTT. Characteristics of patients positive for MOG-IgG in the ONTT support the previously described phenotype of MOG-IgG optic neuritis. Myelin oligodendrocyte glycoprotein-related disease appears to be a different entity than multiple sclerosis. Overall, AQP4-IgG and MOG-IgG may be less common in isolated optic neuritis than previously reported. PMID- 29470573 TI - Factors Associated With Health-Related Quality of Life in Medically and Surgically Treated Patients With Glaucoma. AB - Importance: Health-related quality of life (HRQOL) is often reduced with glaucoma, but associated factors are poorly understood. Objective: To determine factors associated with reduced HRQOL in medically and surgically treated patients with glaucoma. Design, Setting, and Participants: Prospective cohort study at a tertiary referral glaucoma practice, with 160 consecutive, prospectively enrolled medically or surgically treated adult patients with glaucoma. Main Outcome and Measures: All patients completed 2 HRQOL questionnaires (the 25-item National Eye Institute Visual Function Questionnaire and the Adult Strabismus-20 questionnaire [AS-20]). Thirty-six patients had undergone glaucoma drainage device surgery, 51 underwent trabeculectomy, and 73 were medically treated. Factors considered for association with HRQOL in multiple regression analyses were age, sex, best-eye and worst-eye mean deviation on Humphrey visual fields, treatment modality, best-eye and worst-eye visual acuity, and diplopia. Results: The mean (SD) age of participants was 69 (13) years, 63% were female, 97% were white, 93% were not Hispanic, and the mean deviation (SD) was -13 (10) dB. Reduced HRQOL was associated with worse diplopia (Diplopia Questionnaire score) on 6 subscales (range of partial r2 [rp2], 0.207-0.069). Reduced HRQOL was associated with lower best-eye mean deviation on 5 of 6 subscales (rp2 range, 0.379-0.027), lower worst-eye mean deviation on 4 of 6 (rp2 range, 0.242-0.046), treatment group on 3 of 6 (rp2 range, 0.190-0.025), lower worst-eye visual acuity on 5 of 6 (rp2 range, 0.063-0.025), lower best-eye visual acuity on 2 of 6 (rp2 range, 0.032-0.017), and younger age on 2 of 6 (rp2 range, 0.021-0.014). In adjusted analyses, glaucoma drainage device was associated with worse HRQOL in 3 AS-20 subscales compared with trabeculectomy and 2 AS-20 subscales compared with medical. Differences ranged from -14.7 to -7.4, with half the absolute magnitude of the full range of the 95% CI ranging from 9.2 to 5.7. Conclusions and Relevance: Our findings support the assertion that reduced HRQOL is common in surgically and medically treated patients with glaucoma. Overall, poor HRQOL in patients with glaucoma is moderately associated with worse diplopia, lower mean deviation on visual field testing in either eye, poorer visual acuity in either eye, treatment type, and younger age. Previous glaucoma drainage device surgery was specifically associated with poorer HRQOL compared with trabeculectomy or medical treatment. Psychosocial effects of glaucoma drainage device should be considered when counseling patients with glaucoma. PMID- 29470574 TI - Changes in Scope of Procedures Performed by Pediatric Otolaryngologists in the Past Decade. AB - Importance: Monitoring current trends in pediatric otolaryngology will help adjust our training and practice paradigms in a way that ensures the long-term viability of the specialty. Objectives: To gauge the current scope of pediatric otolaryngology (ORL) practice within and outside of the United States and to identify changes in caseload over the past decade. Design, Setting, and Participants: An online survey was sent to pediatric ORL chairs and/or fellowship directors at 42 institutions in the United States and abroad. For 59 procedures, respondents were asked to estimate the percentage of cases performed by their department, determine whether this percentage has changed over the past 10 years (2006-2016), and identify any other specialties performing the procedure. Data were collected during a 2-week period in October 2016, from October 7 through 21, and analyzed from November 2016 through February 2017. Main Outcomes and Measures: Main outcomes included the percentage of operations currently performed by the respondent's department for each procedure; whether this percentage has decreased, increased, or remained the same over the past decade; other specialties that perform each procedure; and any procedures added to or eliminated from the respondent's practice over the past decade. Results: Respondents from 33 of the 42 academic institutions completed the survey (23 in the United States and 10 international; 79% response rate). Respondents reported the least involvement in procedures pertaining to facial plastic and reconstructive surgery, aerodigestive endoscopy, and congenital anomalies. Conversely, a mean (SD) of 91% (7%) reported performing 90% to 100% of otology, airway, rhinology, and general procedures. A mean (SD) of 82% (11%) reported that their department's involvement in each procedure has remained the same from 2006 to 2016. Conclusions and Relevance: The specialty of pediatric ORL has evolved over the past decade. There has been a notable decline in involvement in facial plastic and reconstructive surgery and treatment of vascular malformations and esophageal disorders. The management of thyroid disease is in flux. Monitoring current trends to adjust training and practice paradigms will ensure the long term viability of the specialty.

PMID- 29470579 TI - Defining the Most Appropriate Primary End Point in Phase 2 Trials of Immune Checkpoint Inhibitors for Advanced Solid Cancers: A Systematic Review and Meta analysis. AB - Importance: Checkpoint inhibitors have a unique mechanism of action that differs from chemotherapy or targeted therapies. The validity of objective response rate (ORR) as a surrogate for progression-free survival (PFS) and overall survival (OS) in checkpoint-inhibitor trials is uncertain. Objective: To determine the types of primary end points used in phase 2 checkpoint-inhibitor trials, and to assess the strength of associations for ORR with PFS and OS. Data Sources: Trials listed in electronic databases from 2000 to 2017 (PREMEDLINE, MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials). Study Selection: Advanced solid cancers in phase 2 and phase 3 trials. Data Extraction and Synthesis: Correlations between ORR odds ratios and hazard ratios (HRs) for PFS and OS were examined for randomized comparisons. Within checkpoint-inhibitor treatment arms, correlations for ORR with 6-month PFS and 12-month OS rates were examined. All analyses were weighted by trial size. Multivariable models to predict 6-month PFS and 12-month OS rates from ORR were developed and their performance validated in an independent sample of trials. Main Outcomes and Measures: Correlation coefficient (r) of ORR with PFS and OS. Results: Of 87 phase 2 trials identified, ORR was the most common (52 [60%]) primary end point. Twenty randomized clinical trials with 25 treatment comparisons were identified. Checkpoint-inhibitor therapy was associated with pooled ORR of 24% (95% CI, 18% 31%). For randomized comparisons, r between ORR odds ratio and PFS HR was 0.63 (95% CI, 0.35-0.89), ORR odds ratio and OS HR was 0.57 (95% CI, 0.23-0.89), and between PFS HR and OS HR was 0.42 (95% CI, 0.04-0.81). Within the checkpoint inhibitor arms, r correlation coefficients between ORR with 6-month PFS, ORR with 12-month OS, and 6-month PFS with 12-month OS were 0.37 (95% CI, -0.06 to 0.95), 0.08 (95% CI, -0.17 to 0.70), and 0.74 (95% CI, 0.57-0.92), respectively. In validation, when 6-month PFS was used to predict 12-month OS, there was a good calibration between actual and predicted 12-month OS. When ORR was used to predict 6-month PFS and 12-month OS rates, respectively, the actual vs predicted rates calibrated poorly. Conclusions and Relevance: In checkpoint-inhibitor trials, ORR correlated poorly with OS. For future phase 2 studies, 6-month PFS rate is recommended as an end point.

PMID- 29470582 TI - Prognostic Factors for Complete Response to Ibrutinib in Patients With Chronic Lymphocytic Leukemia: A Pooled Analysis of 2 Clinical Trials. AB - Importance: Ibrutinib, a first-in-class Bruton tyrosine kinase inhibitor taken once daily, is approved in the United States for patients with chronic lymphocytic leukemia/small lymphocytic lymphoma and allows for treatment without chemotherapy. Extended treatment with ibrutinib has demonstrated increased complete response (CR) rates over time. Objective: To analyze baseline factors that predict CR in patients with chronic lymphocytic leukemia/small lymphocytic lymphoma treated with ibrutinib. Design, Setting, and Participants: Univariate and multivariate analyses of pooled data from 2 clinical trials were used to assess the prognostic value of baseline factors associated with CR in 327 patients from the PCYC-1102 and PCYC-1112 studies treated with single-agent ibrutinib. Participants were followed up in academic and community medical centers in the United States, the United Kingdom, Australia, France, Italy, Ireland, Poland, Spain, and Austria. Main Outcomes and Measures: Odds ratio (OR) of CR rate. Results: The 327 patients included in this analysis had a median age of 67 years (range, 30-86 years) and 227 (69.4%) were male. At baseline, 185 patients (56.6%) had bulky disease (lymph node >=5 cm), 184 (56.3%) had advanced stage disease, and 182 (55.7%) had an Eastern Cooperative Oncology Group performance status of 1 or higher. Thirty-one patients (9.5%) were in the first line setting; 38 (11.6%) had undergone 1 previous therapy, 81 (24.8%) had undergone 2, and 177 (54.1%) had undergone 3 or more; patients with relapsed/refractory disease had undergone a median of 3 (range, 0-12) previous therapies. Median time on study was 26.4 months (range, 0.3-55.6 months). Thirty two of the 327 patients (9.8%) treated with ibrutinib had a CR (PCYC-1102: relapsed/refractory, 12 of 101 [11.9%]; treatment-naive, 8 of 31 [25.8%]; and PCYC-1112: 12 of 195 [6.2%]). The median time to CR for these patients was 14.7 months (range, 4.6-47.1 months). Univariate analysis of baseline factors showed that bulky disease, clinical stage, number of previous therapies, and beta2 microglobulin concentration had a significant effect on the odds of CR. The final multivariate model showed that patients with no previous therapy vs patients with at least 1 previous therapy (OR, 2.65; 95% CI, 1.01-6.95; P = .047) and patients without bulky disease (lymph node <5 cm) vs those with bulky disease (lymph node >=5 cm [OR, 4.97; 95% CI, 1.91-12.91; P = .001]) had an increased likelihood of CR. Conclusions and Relevance: Patients receiving ibrutinib as a first-line therapy for chronic lymphocytic leukemia and those without bulky disease had a better likelihood of CR to treatment. The CR rate with continued longer-term ibrutinib treatment was higher than in previous reports. Trial Registration: clinicaltrials.gov Identifiers: NCT01105247 and NCT01578707.

AB - The Caregiver Advise, Record, Enable (CARE) Act has the potential to make a positive impact in the lives of Latino older adults and their caregivers. As Latino individuals are the fastest growing older adult population, the number of Latino families and caregivers is also expected to grow, particularly among those providing care for someone with Alzheimer's disease or other dementias. Caregiving has been considered a culturally embedded value among Latino individuals. Although few studies have focused on caregiving in this population, those that exist suggest that Latino caregivers struggle to find bilingual and bicultural support and information and show higher levels of distress and health disparities. The purpose of the CARE Act is to help and support family caregivers when older adults are admitted to the hospital and during care transitions. The current article examines the potential implications of this state law, specifically on Latino individuals, including recommendations for policy implementation.

AB - OBJECTIVE: Snapping of the iliotibial band over the greater trochanter should be eliminated by reducing tension via lengthening, release, and incision of the iliotibial band. INDICATIONS: Positive clinical examination and painful snapping of the iliotibial band over the greater trochanter, despite extensive conservative treatments, for over 6 months. CONTRAINDICATIONS: Weakness of the abductor muscles with positive Trendelenburg sign. SURGICAL TECHNIQUE: Direct approach to the iliotibial tract. The snapping of the tract over the greater trochanter can be provoked and observed in situ via internal rotation and adduction of the hip. Lengthening of the iliotibial band is performed with a tongue-shape flap technique ("Griffelschachtelplastik") directly over the greater trochanter. This leads to simultaneous release and incision over the greater trochanter. Hereafter, no snapping of the tract should be observed upon motion analysis. POSTOPERATIVE MANAGEMENT: Pain-adapted mobilization with full weightbearing, no active abduction against resistance, and no adduction over and exceeding the 0-degree level for 6 weeks. RESULTS: The snapping of the iliotibial band could be eliminated in all cases. Apart from 2 patients with previous surgery who still complain of unimproved pain, improvement of symptoms with consequent subjective satisfaction with the outcome of surgery was reported in all cases.

AB - BACKGROUND: Social inequalities in health can already be found among children and adolescents to the disadvantage of socially deprived population groups. This paper aims to detect, whether differences in subjective health, mental health and health behavior among young people are due to the secondary school type attended and whether these associations exist independently of the family's socioeconomic position (SEP). METHODS: The data basis was the German Health Interview and Examination Survey for Children and Adolescents (KiGGS Wave 1, 2009-2012). Data of 11- to 17-year-old girls and boys (n = 4665) who attend different types of secondary schools in Germany were analyzed. The dependent variables were self rated health, findings of the Strengths and Difficulties Questionnaire (SDQ) for the detection of psychological abnormalities, as well as self-reported information regarding leisure sport, tobacco, and alcohol consumption. Prevalence and odds ratios (ORs) based on logistic regressions are shown. RESULTS: For the majority of the examined indicators, it can be shown that adolescents in lower secondary schools are more likely to report worse self-rated health and mental problems and engage in unhealthy behavior than peers in grammar schools ("Gymnasium"). The differences decrease after controlling for family's SEP but mostly remain statistically significant. Adolescents who don't attend grammar schools are most strongly disadvantaged in terms of inattention/hyperactivity for both gender (OR: 2.29 [1.70-3.08]), smoking among girls (2.91 [1.85-4.57]) and physical inactivity (no leisure sport) among boys (OR: 2.71 [1.85-3.95]). DISCUSSION: Unequal health opportunities should be viewed in relation to people's living conditions. For adolescents, school constitutes an important setting for learning, experience, and health. The results indicate divergent needs of school based health promotion and prevention regarding differences among gender and type of school.

AB - Shoulder arthroplasties in specialized centers are routine procedures with an increasing number of operations in the developed countries. Restoration of pain free shoulder function requires an intensive, specific and individual rehabilitation program for each patient. There is a phase-like course with different specific demands and measures that extends over a period of several weeks. Return to sport and a pain free function for activities of daily living resulting in a high patient satisfaction can routinely be expected. This excellent perspective, extent and intensity of the rehabilitation program shall be part of the preoperative decision making.

PMID- 29470593 TI - Increased Gi protein signaling potentiates the negative chronotropic effect of adenosine in the SHR right atrium. AB - Hypertension is a risk factor for cardiovascular diseases, which have been associated with dysfunction of sympathetic and purinergic neurotransmission. Therefore, herein, we evaluated whether modifications of adenosine receptor signaling may contribute to the cardiac dysfunction observed in hypertension. Isolated right atria from spontaneously hypertensive (SHR) or normotensive Wistar rats (NWR) were used to investigate the influence of adenosine receptor signaling cascade in the cardiac chronotropism. Our results showed that adenosine, the endogenous agonist of adenosine receptors, and CPA, a selective agonist of A1 receptor, decreased the atrial chronotropism of NWR and SHR in a concentration- and time-dependent manner, culminating in cardiac arrest (0 bpm). Interestingly, a 3-fold lower concentration of adenosine was required to induce the negative chronotropic effect in SHR atria. Pre-incubation of tissues from both strains with DPCPX, a selective A1 receptor antagonist, inhibited the negative chronotropic effect of CPA, while simultaneous inhibition of A2 and A3 receptors, with ZM241385 and MRS1523, did not change the adenosine chronotropic effects. Moreover, 1 MUg/ml pertussis toxin, which inactivates the Galphai protein subunit, reduced by 80% the negative chronotropic effects of adenosine in the NWR atrium, with minor effects in SHR tissue. These data indicate that the negative chronotropic effect of adenosine in right atrium depends exclusively on the activation of A1 receptors. Moreover, the distinct responsiveness of NWR and SHR atria to pertussis toxin reveals that the enhanced negative chronotropic response of SHR right atrium is probably due to an increased activity of Galphai protein mediated.

PMID- 29470596 TI - Mental health burden in a national sample of American Indian and Alaska Native adults: differences between multiple-race and single-race subgroups. AB - PURPOSE: Research on American Indian and Alaska Native (AIAN) mental health disparities is based largely on either tribal populations or national samples of adults that do not account for multiracial AIANs, even though over 40% of AIANs identify with multiple racial groups. The present investigation extends this research by assessing mental health status in a national sample of multiracial AIAN adults relative to adults who identify exclusively as either AIAN or White. METHODS: 2012 BRFSS data were used to conduct multinomial logistic regression analyses comparing mental health outcomes among respondents who identified as either AIAN and one or more other races (AIAN-MR), AIAN-Single Race (AIAN-SR), or White-SR. RESULTS: After demographic adjustment, the AIAN-MR group reported a higher lifetime prevalence of diagnosed depressive disorder, more days of poor mental health, and more frequent mental distress compared to both the AIAN-SR and White-SR groups. AIAN-MR individuals also had higher levels of Kessler 6 (K6) non specific psychological distress compared to White-SR individuals but not AIAN-SR adults. Differences between AIAN-SR and White-SR adults were found in days of poor mental health, frequent mental distress, and total K6 scores. CONCLUSIONS: These findings help gauge the magnitude of mental health disparities in the U.S. AIAN population and pinpoint AIAN subgroups for whom mental health is particularly problematic. As such, they raise concerns about restrictions that limit the identification of national survey respondents who report multiple race designations. Such restrictions will thwart efforts to understand the causal mechanisms and pathways leading to mental distress among AIAN individuals. PMID- 29470597 TI - Mucosa-associated invariant T cells in malignancies: a faithful friend or formidable foe? AB - Mucosa-associated invariant T (MAIT) cells are a subset of innate-like T lymphocytes known for their ability to respond to MHC-related protein 1 (MR1) restricted stimuli and select cytokine signals. They are abundant in humans and especially enriched in mucosal layers, common sites of neoplastic transformation. MAIT cells have been found within primary and metastatic tumors. However, whether they promote malignancy or contribute to anticancer immunity is unclear. On the one hand, MAIT cells produce IL-17A in certain locations and under certain circumstances, which could in turn facilitate neoangiogenesis, intratumoral accumulation of immunosuppressive cell populations, and cancer progression. On the other hand, they can express a potent arsenal of cytotoxic effector molecules, NKG2D and IFN-gamma, all of which have established roles in cancer immune surveillance. In this review, we highlight MAIT cells' characteristics as they might pertain to cancer initiation, progression, or control. We discuss recent findings, including our own, that link MAIT cells to cancer, with a focus on colorectal carcinoma, as well as some of the outstanding questions in this active area of research. Finally, we provide a hypothetical picture in which MAIT cells constitute attractive targets in cancer immunotherapy. PMID- 29470599 TI - Metabolomics in Plant Stress Physiology. AB - Metabolomics is an essential technology for functional genomics and systems biology. It plays a key role in functional annotation of genes and understanding towards cellular and molecular, biotic and abiotic stress responses. Different analytical techniques are used to extend the coverage of a full metabolome. The commonly used techniques are NMR, CE-MS, LC-MS, and GC-MS. The choice of a suitable technique depends on the speed, sensitivity, and accuracy. This chapter provides insight into plant metabolomic techniques, databases used in the analysis, data mining and processing, compound identification, and limitations in metabolomics. It also describes the workflow of measuring metabolites in plants. Metabolomic studies in plant responses to stress are a key research topic in many laboratories worldwide. We summarize different approaches and provide a generic overview of stress responsive metabolite markers and processes compiled from a broad range of different studies. Graphical Abstract. PMID- 29470598 TI - Heterotopic ossification around the knee after tibial nailing and ipsilateral antegrade and retrograde femoral nailing in the treatment of floating knee injuries. AB - PURPOSE: Floating knee injuries are relatively uncommon injuries. We report the prevalence, location, and severity of heterotopic ossification (HO) around the knee in patients treated with antegrade tibial intramedullary nailing and ipsilateral antegrade versus retrograde femoral intramedullary nailing as well as how the severity of HO around the knee affects knee range of motion (ROM). METHODS: From 2004 to 2014, 26 floating knee injuries were included. Radiographs were reviewed to determine presence, location, and severity of HO. Post-operative knee ROM was determined. RESULTS: A significantly higher prevalence of HO around the knee was detected in the retrograde group (90%) compared to the antegrade group (43%) (p = 0.028). There was a trend for more HO into the patellar tendon occurring in 29% of patients in the antegrade group and 74% in the retrograde group (p = 0.069). The severity of HO was higher for the retrograde group 1.6 +/- 1.0 compared to the antegrade group 0.4 +/- 0.5 (p = 0.004). There was poor correlation between HO severity and knee ROM. CONCLUSIONS: Treatment of floating knee injuries with a retrograde femoral nail was demonstrated to result in a greater likelihood of developing HO and a greater severity of HO around the knee than if treated with an antegrade femoral nail. However, this increased severity of HO is unlikely to affect ROM. LEVEL OF EVIDENCE: III. PMID- 29470600 TI - Genetic Mapping Populations for Conducting High-Resolution Trait Mapping in Plants. AB - Fine mapping of quantitative trait loci (QTL) is the route to more detailed molecular characterization and functional studies of the relationship between polymorphism and trait variation. It is also of direct relevance to breeding since it makes QTL more easily integrated into marker-assisted breeding and into genomic selection. Fine mapping requires that marker-trait associations are tested in populations in which large numbers of recombinations have occurred. This can be achieved by increasing the size of mapping populations or by increasing the number of generations of crossing required to create the population. We review the factors affecting the precision and power of fine mapping experiments and describe some contemporary experimental approaches, focusing on the use of multi-parental or multi-founder populations such as the multi-parent advanced generation intercross (MAGIC) and nested association mapping (NAM). We favor approaches such as MAGIC since these focus explicitly on increasing the amount of recombination that occurs within the population. Whatever approaches are used, we believe the days of mapping QTL in small populations must come to an end. In our own work in MAGIC wheat populations, we started with a target of developing 1,000 lines per population: that number now looks to be on the low side. Graphical Abstract. PMID- 29470601 TI - Expansionary Adaptive Transformations of Socio-Hydrological Systems (SHSs): The Case of Drought in Messara Plain, Crete, Greece. AB - The paper attempts to document the ontology of socio-hydrological systems (SHSs), propose approaches of delimitation of SHSs' (territorial) boundaries, and investigate operational aspects of their adaptation to drought including repercussions on sustainability. To this end, a series of hypotheses are tested: (a) SHSs contain social subsystems with different expectations regarding water resources, different adaptive capacities, adaptation limits and prospects of sustainability, (b) SHSs do not adapt homogenously; some of their subsystems manage optimum adaptation, others fail to adapt and (c) territorial transformation of SHSs (e.g., through expansion of SHSs) may be the result of differential adaptation and sustainability potential within the SHS owing to power relations. After testing above hypotheses in the SHS of Messara Plain, Crete, the authors found out that powerful and dynamic sub-SHSs expand or break the boundaries of the initial SHS by establishing new relationships with other SHSs for the sake of resilience resources. Conversely, powerless sub-SHSs incapable to adapt descend and disappear. Therefore, territorial transformation of SHSs comes about from a combination of successful and failed adaptations, or in other words from different adaptation limits within SHSs. Consequently, water management and local development planning to guarantee adaptability to drought for all should be based on SHSs' analysis and management, not on jurisdictional areas or hydrological basins. PMID- 29470602 TI - Who Really Wants an Ambitious Large-Scale Restoration of the Seine Estuary? A Strategic Analysis of a Science-Policy Interface Locked in a Stalemate. AB - The development of ecosystem knowledge is an essential condition for effective environmental management but using available knowledge to solve environmental controversies is still difficult in "real" situations. This paper explores the conditions under which ecological knowledge could contribute to the environmental strategies and actions of stakeholders at science-policy interface. Ecological restoration of the Seine estuary is an example of an environmental issue whose overall management has run into difficulties despite the production of a large amount of knowledge by a dedicated organization, GIP Seine Aval. Thanks to an action-research project, based on a futures study, we analyze the reasons of these difficulties and help the GIP Seine Aval adopt a robust strategy to overcome them. According to our results, most local stakeholders involved in the large-scale restoration project emphasize the need for a clear divide between knowledge production and environmental action. This kind of divide may be strategic in a context where the robustness of environmental decisions is strongly depending on the mobilization of "neutral" scientific knowledge. But in our case study, this rather blocks action because some powerful stakeholders continuously ask for more knowledge before taking action. The construction and analysis of possible future scenarios has led to three alternative strategies being identified to counter this stalemate situation: (1) to circumvent difficulties by creating indirect links between knowledge and actions; (2) to use knowledge to sustain advocacy for the interests of each and every stakeholder; (3) to involve citizens in decisions about knowledge production and use, so that environmental issues weight more on the local political agenda. PMID- 29470603 TI - Cardiac-gated intravoxel incoherent motion diffusion-weighted magnetic resonance imaging for the investigation of intracranial cerebrospinal fluid dynamics in the lateral ventricle: a feasibility study. AB - PURPOSE: Intravoxel incoherent motion (IVIM) in diffusion-weighted magnetic resonance imaging (DW-MRI) attributes the signal attenuation to the molecular diffusion and to a faster pseudo-diffusion. Purpose of the study was to demonstrate the feasibility of IVIM for the investigation of intracranial cerebrospinal fluid (CSF) dynamics. METHODS: Cardiac-gated DW-MRI images with fifteen b-values (0-1300s/mm2) along three orthogonal directions (mediolateral (ML), anteroposterior (AP), and craniocaudal (CC)) were acquired during maximum systole and diastole in 10 healthy volunteers (6 males, mean age 36 +/- 15 years). A pixel-wise bi-exponential fitting with an iterative nonparametric algorithm was carried out to calculate the following parameters: diffusion coefficient (D), fast diffusion coefficient (D*), and fraction of fast diffusion (f). Region of interest measurements were performed in both lateral ventricles. Comparison of IVIM parameters was performed among two cardiac cycle acquisitions and among the diffusion-encoding directions using a paired Student's t test. RESULTS: f significantly (p < 0.05) depended on the diffusion-encoding direction and on the cardiac cycle (diastole AP 0.30 +/- 0.13, ML 0.22 +/- 0.12, CC 0.26 +/ 0.17; systole AP 0.45 +/- 0.17, ML 0.34 +/- 0.15, CC 0.40 +/- 0.21). Neither a cardiac cycle nor a direction dependency was found among mean D values (which is in line with the expected intraventricular isotropic diffusion) and D* values (p > 0.05 each). CONCLUSION: The fraction of fast diffusion from IVIM is feasible to detect a direction-dependent and cardiac-dependent pulsatile CSF flow within the lateral ventricles allowing for quantitative monitoring of CSF dynamics. This technique might provide opportunities to further investigate the pathophysiology of various neurological disorders involving altered CSF dynamics. PMID- 29470604 TI - Cathepsin H deficiency in mice induces excess Th1 cell activation and early-onset of EAE though impairment of toll-like receptor 3 cascade. AB - OBJECTIVE: The objective of this study is to investigate the role of cathepsin H (CatH), a lysosomal cysteine protease, in the development of experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis. METHODS: EAE was induced in CatH-deficient mice (CatH-/-) and wild-type littermates (+/+) using myelin oligodendrocyte glycoprotein (MOG) 35-55. The effects of CatH deficiency were determined by clinical scoring, mRNA expression levels of Tbx21, Rorc and FoxP3, protein levels of poly(I:C)-induced toll-like receptor 3 (TLR3) and phosphorylation of IRF3, and secretion of interferon-beta (IFN-beta) by splenocytes. RESULTS AND CONCLUSIONS: CatH-/- showed a significantly earlier disease onset of EAE and increased Th1 cell differentiation in splenocytes. Splenocytes prepared from immunized CatH-/- showed a significant decrease in poly(I:C)-induced increased TLR3 expression, interferon regulatory factor 3 (IRF3) phospholylation and IFN-beta secretion. Therefore, CatH deficiency impaired TLR3-mediated activation of IRF3 and consequent secretion of IFN-beta from dendritic cells, leading to the enhancement of Th1 cell differentiation and consequent early disease onset of EAE.

AB - OBJECTIVES: The retroauricular fascia flap (RFF) is one of the most commonly used vascularized linings for auriculocephalic sulcus reconstruction in staged total auricular reconstruction. This study aims to investigate the histomorphometric features regarding the retroauricular fascia. METHODS: Histological evaluation included qualitative observation and quantitative analysis of sections of RFF stained with hematoxylin and eosin, Masson's trichrome, Elastica van Gieson, CD31, and Lyve-1. Ultrasonographic evaluation included measurement of the thickness of the superficial layer of the retroauricular fascia (RFF origin) at three different positions in microtia patients. P < 0.05 was considered statistically significant. RESULTS: RFF was a thin, highly organized layer with mainly collagen fibers. From its superior to inferior portions, the percentage of collagen fibers differed significantly (superior 87.57 +/- 10.85%, middle 68.29 +/- 29.02%, inferior 53.31 +/- 33.33%, p < 0.05). The percentages of elastic fibers in the superior (4.86 +/- 5.17%) and middle (5.05 +/- 5.37%) areas were higher than that in the inferior (2.14 +/- 2.42%, p < 0.05). RFF blood vessel density (20* magnification) decreased significantly from the superior to inferior portions (superior 6.39 +/- 1.18, middle 5.17 +/- 1.15, inferior 2.67 +/- 0.78, p < 0.05). Lymphatic vessel density (20* magnification) also decreased significantly from the superior to inferior regions (superior 6.80 +/- 0.62, middle 5.26 +/- 1.17, inferior 2.11 +/- 0.46, p < 0.05). Thickness of the superficial layer of retroauricular fascia increased significantly from the superior to inferior regions (superior 0.29 +/- 0.06 mm, middle 0.36 +/- 0.09 mm, inferior 0.53 +/- 0.14 mm, p < 0.001). CONCLUSIONS: From cranial to caudal, the RFF became thicker, less elastic, and less vascularized, and contained fewer lymphatic vessels. Therefore, when the retroauricular fascia is large enough, the superior portion would be preferred for RFF in auriculocephalic sulcus reconstruction.

PMID- 29470605 TI - Considering the context: social factors in responses to drugs in humans. AB - BACKGROUND: Drugs are typically used in social settings. Here, we consider two factors that may contribute to this observation: (i) the presence of other people may enhance the positive mood effects of a drug, and conversely, (ii) drugs may enhance the value of social stimuli. METHODS: We review evidence from controlled laboratory studies with human volunteers, which investigated either of these interactions between social factors and responses to drugs. We examine the bidirectional effects of social stimuli and single doses of alcohol, stimulants, opioids, and cannabis. RESULTS: All four classes of drugs interact with social contexts, but the nature of these interactions varies across drugs, and depends on whether the context is positive or negative. CONCLUSIONS: Alcohol and stimulant drugs enhance the attractiveness of social stimuli and the desire to socialize, and social contexts, in turn, enhance these drugs' effects. In contrast, opioids and cannabis have subtler effects on social interactions and their effects are less influenced by the presence of others. Overall, there is stronger evidence that drugs enhance positive social contexts than that they dampen the negativity of unpleasant social settings. Controlled research is needed to understand the interactions between drugs of abuse and social contexts, to model and understand the determinants of drug use outside the laboratory. PMID- 29470607 TI - The Relationship Between Patients' Personality Traits and Breast Reconstruction Process. AB - BACKGROUND: Breast reconstruction after mastectomy is a part of breast cancer treatment. There is a lack of data regarding the impact of reconstruction over psychological traits and quality of life. The aim of this study is to evaluate personality changes in patients who underwent reconstructive surgery. METHODS: Thirty-seven women underwent breast reconstruction. These women took the Crown Crisp Experiential Index before and after the different procedures. The questionnaire analyzes: (a) the satisfaction level with personal relationships before and after surgery, and the level of satisfaction with surgical results and (b) personality index. Comparisons of preoperative and postoperative personality traits were made by using the Crown-Crisp test and analyzed by Chi-square test. Correlations between preoperative concerns and CCEI traits and correlations between physical aspects and Crown-Crisp, both preoperatively and postoperatively, were performed using the Spearman test. RESULTS: We found statistically significant differences in the following traits: anxiety anticipating possible technique failures (p = 0.01); cancer recurrence (p = 0.04); dissatisfaction with results (p = 0.02); phobic anxiety for possible technique failure (p = 0.03); obsessionality with possible technique failure (p = 0.01); preoccupations around cancer recurrence (p = 0.01) and dissatisfaction with results (p = 0.03); somatic of technique failure (p = 0.05); and finally, depression and hysteria traits in response to surgical procedures except anesthesia. CONCLUSION: This prospective study suggests that personality traits define perceptions of body image, which has an influence over quality of life and satisfaction with results.

PMID- 29470608 TI - Bacterial Communities Inhabiting the Sponge Biemna fortis, Sediment and Water in Marine Lakes and the Open Sea. AB - Marine lakes are small bodies of landlocked seawater that are isolated from the open sea and have been shown to house numerous rare and unique taxa. The environmental conditions of the lakes are also characterised by lower pH and salinity and higher temperatures than generally found in the open sea. In the present study, we used a 16S rRNA gene barcoded pyrosequencing approach and a predictive metagenomic approach (PICRUSt) to examine bacterial composition and function in three distinct biotopes (sediment, water and the sponge species Biemna fortis) in three habitats (two marine lakes and the open sea) of the Berau reef system, Indonesia. Both biotope and habitat were significant predictors of higher taxon abundance and compositional variation. Most of the variation in operational taxonomic unit (OTU) composition was related to the biotope (42% for biotope alone versus 9% for habitat alone and 15% combined). Most OTUs were also restricted to a single biotope (1047 for B. fortis, 6120 for sediment and 471 for water). Only 98 OTUs were shared across all three biotopes. Bacterial communities from B. fortis, sediment and water samples were, however, also distinct in marine lake and open sea habitats. This was evident in the abundance of higher bacterial taxa. For example, the phylum Cyanobacteria was significantly more abundant in samples from marine lakes than from the open sea. This difference was most pronounced in the sponge B. fortis. In line with the compositional differences, there were pronounced differences in predicted relative gene count abundance among biotopes and habitats. Of particular interest was the predicted enrichment in B. fortis from the marine lakes for pathways including DNA replication and repair and the glutathione metabolism. This may facilitate adaptation of host and microbes to life in 'stressful' low pH, low salinity and/or high temperature environments such as those encountered in marine lakes. PMID- 29470609 TI - [New aspects in systemic treatment of atopic dermatitis]. AB - In severe cases of atopic dermatitis (AD) systemic treatment is indicated. So far, cyclosporine and systemic glucocorticosteroids represented the only systemic treatment options approved for the indications of AD in Germany; however, from clinical practice there is increasing evidence for beneficial therapeutic effects in AD by other immunosuppressive or immunomodulatory substances, such as mycophenolate, methotrexate, alitretinoin and ustekinumab. Beyond this, ongoing research activities focus on a better understanding of genetic and immunological aspects of this chronic inflammatory skin disease. Regarding treatment with mycophenolate, genetic polymorphisms in AD patients could be identified that might predict responsiveness to this medication. Moreover, several new substances specifically targeting inflammation in AD are currently being studied and the first promising treatment effects on skin condition and pruritic symptoms of AD could be observed. As an exceptional result of this development in September 2017 in Europe and therefore in Germany the first biologic as first-line treatment was approved for the indication of moderate to severe AD in adults. Dupilumab is a human monoclonal IgG4 antibody that blocks a subunit of the interleukin (IL)-4 and IL-13 receptors, thus inhibiting the proinflammatory effects of these cytokines. Furthermore, the cytokine IL-13 itself, the IL-31 receptor, which is of particular relevance for pruritus in AD, the histamine-4-receptor and Janus kinases represent further promising targets currently being investigated in clinical trials for the treatment of AD. PMID- 29470610 TI - A comparison of new drugs approved by the FDA, the EMA, and Swissmedic: an assessment of the international harmonization of drugs. AB - INTRODUCTION: This study compared the characteristics of new human drugs approved by the Food and Drug Administration (FDA), the European Medicine Agency (EMA), and Swissmedic (SMC) in the period 2007 to 2016. METHODS: The list of new drugs and therapeutic biologics approved by the FDA, the EMA, and SMC in the period 2007 to 2016 was collected from websites of those agencies. The study included regulatory information, approval date, and indication for each drug. Descriptive statistical t tests and x2-tests were performed for the analysis. RESULTS: From 2007 to 2016, 134 new drugs were approved by all three regulatory agencies. Overall, 66.4% of the drugs were first approved by the FDA, 30.6% by the EMA, and 3.0% by SMC. The difference in approval dates between SMC and the EMA, SMC and the FDA, and the FDA and the EMA were statistically significant. The indications approved by the FDA, the EMA, and SMC for the same drugs were similar in content for 23.1% drugs and different in 76.9% of the drugs. Significant differences in indications existed between the FDA and SMC and the FDA and the EMA, but not between the EMA and SMC. CONCLUSION: There were differences in the characteristics of new drugs approved by the EMA, the FDA, and SMC in the period 2007-2016. Overall, two thirds of the new drugs were first approved by the FDA. Differences in indications were found in three out of four new drugs approved by the three regulatory agencies. Despite international drug regulation harmonization efforts, significant differences in the characteristics of new drugs approved by different agencies persist. PMID- 29470611 TI - Osteoporosis in Rheumatic Diseases: Anti-rheumatic Drugs and the Skeleton. AB - Osteoporosis in rheumatic diseases is a very well-known complication. Systemic inflammation results in both generalized and localized bone loss and erosions. Recently, increased knowledge of inflammatory process in rheumatic diseases has resulted in the development of potent inhibitors of the cytokines, the biologic DMARDs. These treatments reduce systemic inflammation and have some effect on the generalized and localized bone loss. Progression of bone erosion was slowed by TNF, IL-6 and IL-1 inhibitors, a JAK inhibitor, a CTLA4 agonist, and rituximab. Effects on bone mineral density varied between the biological DMARDs. Medications that are approved for the treatment of osteoporosis have been evaluated to prevent bone loss in rheumatic disease patients, including denosumab, cathepsin K, bisphosphonates, anti-sclerostin antibodies and parathyroid hormone (hPTH 1 34), and have some efficacy in both the prevention of systemic bone loss and reducing localized bone erosions. This article reviews the effects of biologic DMARDs on bone mass and erosions in patients with rheumatic diseases and trials of anti-osteoporotic medications in animal models and patients with rheumatic diseases. PMID- 29470612 TI - Efficacy of aliskiren supplementation for heart failure : A meta-analysis of randomized controlled trials. AB - BACKGROUND: Aliskiren might be beneficial for heart failure. However, the results of various studies are controversial. We conducted a systematic review and meta analysis to explore the efficacy of aliskiren supplementation for heart failure. METHODS: PubMed, Embase, Web of Science, EBSCO, and the Cochrane Library databases were systematically searched. Randomized controlled trials (RCTs) assessing the efficacy of aliskiren for heart failure were included. Two investigators independently searched for articles, extracted data, and assessed the quality of included studies. The meta-analysis was performed using the random effect model. RESULTS: Five RCTs comprising 1973 patients were included in the meta-analysis. Compared with control interventions in heart failure, aliskiren supplementation was found to significantly reduce NT-proBNP levels (standardized mean difference [SMD] = -0.12; 95% CI = -0.21 to -0.03 pg/ml; p = 0.008) and plasma renin activity (SMD = -0.66; 95% CI = -0.89 to -0.44 ng/ml.h; p < 0.00001) while increasing plasma renin concentration (SMD = 0.52; 95% CI = 0.30-0.75 ng/l; p < 0.00001); however, it demonstrated no significant influence on BNP levels (SMD = -0.08; 95% CI = -0.31-0.15 pg/ml; p = 0.49), mortality (RR = 0.97; 95% CI = 0.79-1.20; p = 0.79), aldosterone levels (SMD = -0.09; 95% CI = -0.32-0.14 pmol/l; p = 0.44), adverse events (RR = 3.03; 95% CI = 0.18-49.51; p = 0.44), and serious adverse events (RR = 1.34; 95% CI = 0.54-3.33; p = 0.53). CONCLUSION: Aliskiren supplementation was found to significantly decrease NT-proBNP levels and plasma renin activity and to improve plasma renin concentration in the setting of heart failure. PMID- 29470614 TI - Roles of posttherapy 18F-FDG PET/CT in patients with advanced squamous cell carcinoma of the uterine cervix receiving concurrent chemoradiotherapy. AB - PURPOSE: To assess the clinical roles of [18F]fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) performed 2-3 months after completion of concurrent chemoradiotherapy (CCRT), along with pretherapy characteristics, in patients with advanced squamous cell carcinoma of the uterine cervix enrolled in a prospective randomized clinical trial. METHODS: Posttherapy PET/CT in patients with advanced FIGO stage or positive pelvic or para-aortic lymph node (PALN) defined on pretherapy PET/CT was classified as positive, equivocal, or negative. Overall survival (OS) rates between patients with different PET/CT results are compared. Pretherapy characteristics are examined for association with posttherapy PET/CT results and for prognostic significance in patients with equivocal or negative PET/CT. RESULTS: PET/CT scans (n = 55) were positive, equivocal and negative in 9, 13 and 33 patients, respectively. All patients with positive scans were confirmed to have residual or metastatic disease and died despite salvage therapies. There is a significant OS difference between patients with positive and equivocal scans (P < .001) but not between patients with equivocal and negative scans (P = .411). Positive pretherapy PALN is associated with positive posttherapy PET/CT (P = .033) and predicts a poorer survival in patients with equivocal or negative posttherapy PET/CT (P < .001). CONCLUSIONS: Positive PET/CT 2-3 months posttherapy implies treatment failure and novel therapy is necessary to improve outcomes for such patients. A more intense posttherapy surveillance may be warranted in patients with positive pretherapy PALN. PMID- 29470615 TI - Pre-dosing with lilotomab prior to therapy with 177Lu-lilotomab satetraxetan significantly increases the ratio of tumor to red marrow absorbed dose in non Hodgkin lymphoma patients. AB - PURPOSE: 177Lu-lilotomab satetraxetan is a novel anti-CD37 antibody radionuclide conjugate for the treatment of non-Hodgkin lymphoma (NHL). Four arms with different combinations of pre-dosing and pre-treatment have been investigated in a first-in-human phase 1/2a study for relapsed CD37+ indolent NHL. The aim of this work was to determine the tumor and normal tissue absorbed doses for all four arms, and investigate possible variations in the ratios of tumor to organs at-risk absorbed doses. METHODS: Two of the phase 1 arms included cold lilotomab pre-dosing (arm 1 and 4; 40 mg fixed and 100 mg/m2 BSA dosage, respectively) and two did not (arms 2 and 3). All patients were pre-treated with different regimens of rituximab. The patients received either 10, 15, or 20 MBq 177Lu-lilotomab satetraxetan per kg body weight. Nineteen patients were included for dosimetry, and a total of 47 lesions were included. The absorbed doses were calculated from multiple SPECT/CT-images and normalized by administered activity for each patient. Two-sided Student's t tests were used for all statistical analyses. RESULTS: Organs with distinct uptake of 177Lu-lilotomab satetraxetan, in addition to tumors, were red marrow (RM), liver, spleen, and kidneys. The mean RM absorbed doses were 0.94, 1.55, 1.44, and 0.89 mGy/MBq for arms 1-4, respectively. For the patients not pre-dosed with lilotomab (arms 2 and 3 combined) the mean RM absorbed dose was 1.48 mGy/MBq, which was significantly higher than for both arm 1 (p = 0.04) and arm 4 (p = 0.02). Of the other organs, the highest uptake was found in the spleen, and there was a significantly lower spleen absorbed dose for arm-4 patients than for the patient group without lilotomab pre-dosing (1.13 vs. 3.20 mGy/MBq; p < 0.01). Mean tumor absorbed doses were 2.15, 2.31, 1.33, and 2.67 mGy/MBq for arms 1-4, respectively. After averaging the tumor absorbed dose for each patient, the patient mean tumor absorbed dose to RM absorbed dose ratios were obtained, given mean values of 1.07 for the patient group not pre-dosed with lilotomab, of 2.16 for arm 1, and of 4.62 for arm 4. The ratios were significantly higher in both arms 1 and 4 compared to the group without pre dosing (p = 0.05 and p = 0.02). No statistically significant difference between arms 1 and 4 was found. CONCLUSIONS: RM is the primary dose-limiting organ for 177Lu-lilotomab satetraxetan treatment, and pre-dosing with lilotomab has a mitigating effect on RM absorbed dose. Increasing the amount of lilotomab from 40 mg to 100 mg/m2 was found to slightly decrease the RM absorbed dose and increase the ratio of tumor to RM absorbed dose. Still, both pre-dosing amounts resulted in significantly higher tumor to RM absorbed dose ratios. The findings encourage continued use of pre-dosing with lilotomab. PMID- 29470616 TI - Automated SPECT analysis compared with expert visual scoring for the detection of FFR-defined coronary artery disease. AB - PURPOSE: Traditionally, interpretation of myocardial perfusion imaging (MPI) is based on visual assessment. Computer-based automated analysis might be a simple alternative obviating the need for extensive reading experience. Therefore, the aim of the present study was to compare the diagnostic performance of automated analysis with that of expert visual reading for the detection of obstructive coronary artery disease (CAD). METHODS: 206 Patients (64% men, age 58.2 +/- 8.7 years) with suspected CAD were included prospectively. All patients underwent 99mTc-tetrofosmin single-photon emission computed tomography (SPECT) and invasive coronary angiography with fractional flow reserve (FFR) measurements. Non corrected (NC) and attenuation-corrected (AC) SPECT images were analyzed both visually as well as automatically by commercially available SPECT software. Automated analysis comprised a segmental summed stress score (SSS), summed difference score (SDS), stress total perfusion deficit (S-TPD), and ischemic total perfusion deficit (I-TPD), representing the extent and severity of hypoperfused myocardium. Subsequently, software was optimized with an institutional normal database and thresholds. Diagnostic performances of automated and visual analysis were compared taking FFR as a reference. RESULTS: Sensitivity did not differ significantly between visual reading and most automated scoring parameters, except for SDS, which was significantly higher than visual assessment (p < 0.001). Specificity, however, was significantly higher for visual reading than for any of the automated scores (p < 0.001 for all). Diagnostic accuracy was significantly higher for visual scoring (77.2%) than for all NC images scores (p < 0.05), but not compared with SSS AC and S-TPD AC (69.8% and 71.2%, p = 0.063 and p = 0.134). After optimization of the automated software, diagnostic accuracies were similar for visual (73.8%) and automated analysis. Among the automated parameters, S-TPD AC showed the highest accuracy (73.5%). CONCLUSION: Automated analysis of myocardial perfusion SPECT can be as accurate as visual interpretation by an expert reader in detecting significant CAD defined by FFR. PMID- 29470617 TI - Effects of the Razor Clam Tagelus plebeius on the Fate of Petroleum Hydrocarbons: A Mesocosm Experiment. AB - The relationship between organisms and contaminants may be a two-way interaction: contaminants affecting the biota and the biota affecting the environmental fate and distribution of the contaminants. This may be especially so for sediment dwelling organisms, because their burrowing and feeding can drastically influence sediment characteristics. The present study looked at the influence of the suspension-feeding stout razor clam Tagelus plebeius on the distribution of crude oil and pyrene in greenhouse mesocosm experiments. Water column turbidity and sediment redox also were monitored during the 15- to 30-day exposures to provide information on the influence of hydrocarbons and the razor clams on environmental conditions. For the experiment with crude oil, sediment was taken from the mesocosms at the end of the experiment, and the hydrocarbon-degradation potential was assessed in incubations with 14C-naphthalene. The experiments used four treatments: hydrocarbons present/absent and razor clams present/absent. Hydrocarbon dosing levels were relatively low (1 mL of oil or 30 mg of pyrene per mesocosm with 22 L of natural sediment and 11 L of seawater). The presence of the razor clams resulted in hydrocarbon concentrations at the sediment surface being 25% lower than in mesocosms without clams. No consistent effects were noted for polycyclic aromatic hydrocarbon (PAH) concentrations in the water column or in subsurface sediment. The naphthalene-degradation potential was elevated for sediment from mesocosms dosed with oil, but the presence of the clams did not affect this potential. The presence of the razor clams resulted in a lowering of water column turbidity, but no effect on sediment redox. The hydrocarbon addition had no effect on turbidity, but sediment redox was lowered. While results show that the presence of the razor clams resulted in a loss of hydrocarbons from the surface sediment, the other results do not provide a clear picture of the underlying mechanisms and the fate of the PAHs lost from the sediment surface. We hypothesize that the loss of surface sediment PAHs was due to burial of surface sediment and possibly bioaccumulation by the clams. While additional research is needed for further insights into underlying mechanisms, the present work demonstrates that the presence of sediment-burrowing suspension feeders decreases hydrocarbon levels in surface sediment. This means that assessments of the impact of an oil spill should pay attention to effects on these organisms and to their influence on the fate and distribution of the spilled oil. PMID- 29470618 TI - Tuning of acyl-ACP thioesterase activity directed for tailored fatty acid synthesis. AB - Medium-chain fatty acids have attracted significant attention as sources of biofuels in recent years. Acyl-ACP thioesterase, which is considered as the key enzyme to determine the carbon chain length, catalyzes the termination of de novo fatty acid synthesis. Although recombinant medium-chain acyl-ACP thioesterase (TE) affects the fatty acid profile in heterologous cells, tailoring of the fatty acid composition merely by engineering a specific TE is still intractable. In this study, the activity of a C8-C10-specific thioesterase FatB2 from Cuphea hookeriana on C10-ACP was quantified twice as high as that on C8-ACP based on a synthetic C8-C16 acyl-ACP pool in vitro. Whereas in vivo, it was demonstrated that ChFatB2 preferred to accumulate C8 fatty acids with 84.9% composition in the ChFatB2-engineered E. coli strain. To achieve C10 fatty acid production, ChFatB2 was rationally tuned based on structural investigation and enzymatic analysis. An I198E mutant was identified to redistribute the C8-ACP flow, resulting in C10 fatty acid being produced as the principal component at 57.6% of total fatty acids in vivo. It was demonstrated that the activity of TE relative to beta ketoacyl-ACP synthases (KAS) directly determined the fatty acid composition. Our results provide a prospective strategy in tailoring fatty acid synthesis by tuning of TE activities based on TE-ACP interaction. PMID- 29470619 TI - Exploring the sequence diversity in glycoside hydrolase family 13_18 reveals a novel glucosylglycerol phosphorylase. AB - In the carbohydrate-active enzyme database, GH13_18 is a family of retaining glycoside phosphorylases that act on alpha-glucosides. In this work, we explored the functional diversity of this family by comparing distinctive sequence motifs in different branches of its phylogenetic tree. A glycoside phosphorylase from Marinobacter adhaerens HP15 that was predicted to have a novel function was expressed and characterised. The enzyme was found to catalyse the reversible phosphorolysis of 2-O-alpha-D-glucosylglycerol with retention of the anomeric configuration, a specificity that has never been described before. Homology modelling, docking and mutagenesis were performed to pinpoint particular acceptor site residues (Tyr194, Ala333, Gln336) involved in the binding of glycerol. The new enzyme specificity provides additional insights into bacterial metabolic routes, being the first report of a phosphorolytic route for glucosylglycerol in a glucosylglycerol-producing organism. Furthermore, glucosylglycerol phosphorylase might be an attractive biocatalyst for the production of the osmolyte glucosylglycerol, which is currently produced on industrial scale by exploiting a side activity of the closely related sucrose phosphorylase. Family GH13_18 has clearly proven to be more diverse than was initially assumed, and the analysis of specificity-determining sequence motifs has shown to be a straightforward and fruitful tool for enzyme discovery. PMID- 29470620 TI - Dengue viruses and promising envelope protein domain III-based vaccines. AB - Dengue viruses are emerging mosquito-borne pathogens belonging to Flaviviridae family which are transmitted to humans via the bites of infected mosquitoes Aedes aegypti and Aedes albopictus. Because of the wide distribution of these mosquito vectors, more than 2.5 billion people are approximately at risk of dengue infection. Dengue viruses cause dengue fever and severe life-threatening illnesses as well as dengue hemorrhagic fever and dengue shock syndrome. All four serotypes of dengue virus can cause dengue diseases, but the manifestations are nearly different depending on type of the virus in consequent infections. Infection by any serotype creates life-long immunity against the corresponding serotype and temporary immunity to the others. This transient immunity declines after a while (6 months to 2 years) and is not protective against other serotypes, even may enhance the severity of a secondary heterotypic infection with a different serotype through a phenomenon known as antibody-depended enhancement (ADE). Although, it can be one of the possible explanations for more severe dengue diseases in individuals infected with a different serotype after primary infection. The envelope protein (E protein) of dengue virus is responsible for a wide range of biological activities, including binding to host cell receptors and fusion to and entry into host cells. The E protein, and especially its domain III (EDIII), stimulates host immunity responses by inducing protective and neutralizing antibodies. Therefore, the dengue E protein is an important antigen for vaccine development and diagnostic purposes. Here, we have provided a comprehensive review of dengue disease, vaccine design challenges, and various approaches in dengue vaccine development with emphasizing on newly developed envelope domain III-based dengue vaccine candidates. PMID- 29470621 TI - Novel sources of resistance to Septoria nodorum blotch in the Vavilov wheat collection identified by genome-wide association studies. AB - KEY MESSAGE: The fungus Parastagonospora nodorum causes Septoria nodorum blotch (SNB) of wheat. A genetically diverse wheat panel was used to dissect the complexity of SNB and identify novel sources of resistance. The fungus Parastagonospora nodorum is the causal agent of Septoria nodorum blotch (SNB) of wheat. The pathosystem is mediated by multiple fungal necrotrophic effector-host sensitivity gene interactions that include SnToxA-Tsn1, SnTox1-Snn1, and SnTox3 Snn3. A P. nodorum strain lacking SnToxA, SnTox1, and SnTox3 (toxa13) retained wild-type-like ability to infect some modern wheat cultivars, suggesting evidence of other effector-mediated susceptibility gene interactions or the lack of host resistance genes. To identify genomic regions harbouring such loci, we examined a panel of 295 historic wheat accessions from the N. I. Vavilov Institute of Plant Genetic Resources in Russia, which is comprised of genetically diverse landraces and breeding lines registered from 1920 to 1990. The wheat panel was subjected to effector bioassays, infection with P. nodorum wild type (SN15) and toxa13. In general, SN15 was more virulent than toxa13. Insensitivity to all three effectors contributed significantly to resistance against SN15, but not toxa13. Genome-wide association studies using phenotypes from SN15 infection detected quantitative trait loci (QTL) on chromosomes 1BS (Snn1), 2DS, 5AS, 5BS (Snn3), 3AL, 4AL, 4BS, and 7AS. For toxa13 infection, a QTL was detected on 5AS (similar to SN15), plus two additional QTL on 2DL and 7DL. Analysis of resistance phenotypes indicated that plant breeders may have inadvertently selected for effector insensitivity from 1940 onwards. We identify accessions that can be used to develop bi-parental mapping populations to characterise resistance-associated alleles for subsequent introgression into modern bread wheat to minimise the impact of SNB. PMID- 29470623 TI - Long-distance longitudinal prostate MRI quality assurance: from startup to 12 months. AB - PURPOSE: To evaluate a 12-month long-distance prostate MRI quality assurance (QA) program. METHODS: The need for IRB approval was waived for this prospective longitudinal QA effort. One academic institution experienced with prostate MRI [~ 1000 examinations/year (Site 2)] partnered with a private institution 240 miles away that was starting a new prostate MRI program (Site 1). Site 1 performed all examinations (N = 249). Four radiologists at Site 1 created finalized reports, then sent images and reports to Site 2 for review on a rolling basis. One radiologist at Site 2 reviewed findings and exam quality and discussed results by phone (~ 2-10 minutes/MRI). In months 1-6 all examinations were reviewed. In months 7-12 only PI-RADS <= 2 and 'difficult' cases were reviewed. Repeatability was assessed with intra-class correlation (ICC). 'Clinically significant cancer' was Gleason >= 7. RESULTS: Image quality significantly (p < 0.001) improved after the first three months. Inter-rater agreement also improved in months 3-4 [ICC: 0.849 (95% CI 0.744-0.913)] and 5-6 [ICC: 0.768 (95% CI 0.619-0.864)] compared to months 1-2 [ICC: 0.621 (95% CI 0.436-0.756)]. PI-RADS <= 2 examinations were reclassified PI-RADS >= 3 in 19% (30/162); of these, 23 had post-MRI histology and 57% (13/23) had clinically significant cancer (5.2% of 249). False-negative examinations [N = 18 (PI-RADS <= 2 and Gleason >= 7)] were more common at Site 1 during months 1-6 [9% (14/160) vs. 4% (4/89)]. Positive predictive values for PI RADS >= 3 were similar. CONCLUSION: Remote quality assurance of prostate MRI is feasible and useful, enabling new programs to gain durable skills with minimal risk to patients. PMID- 29470622 TI - Genetic dissection of wheat panicle traits using linkage analysis and a genome wide association study. AB - KEY MESSAGE: Coincident regions on chromosome 4B for GW, on 5A for SD and TSS, and on 3A for SL and GNS were detected through an integration of a linkage analysis and a genome-wide association study (GWAS). In addition, six stable QTL clusters on chromosomes 2D, 3A, 4B, 5A and 6A were identified with high PVE% on a composite map. The panicle traits of wheat, such as grain number per spike and 1000-grain weight, are closely correlated with grain yield. Superior and effective alleles at loci related to panicles developments play a crucial role in the progress of molecular improvement in wheat yield breeding. Here, we revealed several notable allelic variations of seven panicle-related traits through an integration of genome-wide association mapping and a linkage analysis. The linkage analysis was performed using a recombinant inbred line (RIL) population (173 lines of F8:9) with a high-density genetic map constructed with 90K SNP arrays, Diversity Arrays Technology (DArT) and simple sequence repeat (SSR) markers in five environments. Thirty-five additive quantitative trait loci (QTL) were discovered, including eleven stable QTLs on chromosomes 1A, 2D, 4B, 5B, 6B, and 6D. The marker interval between EX_C101685 and RAC875_C27536 on chromosome 4B exhibited pleiotropic effects for GW, SL, GNS, FSN, SSN, and TSS, with the phenotypic variation explained (PVE) ranging from 5.40 to 37.70%. In addition, an association analysis was conducted using a diverse panel of 205 elite wheat lines with a composite map (24,355 SNPs) based on the Illumina Infinium assay in four environments. A total of 73 significant marker-trait associations (MTAs) were detected for panicle traits, which were distributed across all wheat chromosomes except for 4D, 5D, and 6D. Consensus regions between RAC875_C27536_611 and Tdurum_contig4974_355 on chromosome 4B for GW in multiple environments, between QTSS5A.7-43 and BS00021805_51 on 5A for SD and TSS, and between QSD3A.2-164 and RAC875_c17479_359 on 3A for SL and GNS in multiple environments were detected through linkage analysis and a genome-wide association study (GWAS). In addition, six stable QTL clusters on chromosomes 2D, 3A, 4B, 5A, and 6A were identified with high PVE% on a composite map. This study provides potentially valuable information on the dissection of yield-component traits and valuable genetic alleles for molecular-design breeding or functional gene exploration. PMID- 29470624 TI - Measuring liver T2* and cardiac T2* in a single acquisition. AB - PURPOSE: The purpose of this study is determine if both liver T2* and cardiac T2* can be measured on a single breath-hold acquisition. MATERIALS AND METHODS: For this IRB-approved retrospective study, 137 patients with dedicated Cardiac MRI and Liver MRI examinations obtained sequentially on 1.5T scanners and on the same day were included for analysis. Both the cardiac and liver MRI examinations utilized GRE sequences for quantification of tissue iron. Specifically, T2* was measured using an 8-echo, multi-echo gradient echo single breath-hold sequence. Liver T2* was measured in a blinded manner on images from each of the cardiac and dedicated liver MRI examinations and were correlated. Bland-Altman difference plot was used to assess mean bias. RESULTS: 137 examinations from 93 subjects met inclusion criteria. 10 examination pairs were excluded because the first echo time (TE) on the cardiac MRI was insufficiently short for the very high liver iron content. After exclusion, 127 studies from 89 subjects (67.4% males) were included in the final analysis. The mean subject age (+/- standard deviation) was 11.5 +/- 7.5 years (range 0-29.3 years; median 10.5 years). Mean liver T2* measured on cardiac MRI was 8.3 +/- 7.7 ms and mean liver T2* measured on dedicated liver MRI was 7.8 +/- 7.4 ms (p < 0.001). There was strong positive correlation between the two liver T2* measurements (r = 0.989, p < 0.0001; 95% CI 0.985-0.992). With the exception of borderline outliers, all values fell within two standard deviations on the Bland-Altman difference plots, with a mean bias of 0.5 ms (range - 1.8 to + 2.7 ms). CONCLUSION: In most patients with suspected or known iron overload, a single breath-hold GRE sequence may be sufficient to evaluate the iron concentration (T2*) of both the myocardium and the liver. PMID- 29470625 TI - Fluoroscopy-guided trans-anal decompression tube placement in the treatment of acute colonic pseudo-obstruction: a single center experience. AB - PURPOSE: Acute colonic pseudo-obstruction (ACPO or Ogilvie's syndrome) is a rare but often fatal disease; timely colonic decompression may be essential for successful treatment. This study describes a technique of placing a trans-anal tube via fluoroscopy-guiding and investigates the effect of colon decompression on ACPO. METHODS: Patients undergoing colonic decompression via fluoroscopy guided trans-anal tube placement from April 2015 to May 2017 were included. The technical and clinical successes of this procedure were evaluated. Clinical features and long-term outcomes are described. RESULTS: Decompression was successful in 72.73% (16/22) of the patients; the procedure was considered a clinical success in 50% (11/22) of the patients. 31.82% (7/22) of the patients underwent elective surgery, and only 18.19% (4/22) of the patients need emergency surgery. CONCLUSIONS: Fluoroscopy-guided trans-anal decompression tube placement was an easy and efficient method for treating ACPO. Additionally, ACPO once required emergency surgery, but now may only require elective surgery in certain instances. PMID- 29470626 TI - Living donor liver transplantation: post-operative imaging follow-up of right lobe liver donors. AB - PURPOSE: To identify long-term post-operative imaging findings resulting from right lobe liver donation. METHODS: This retrospective imaging review consisted of 42 adults (20 males, 22 females, mean age 36.6 years, range 18.7-55.9 years) who underwent right lobe liver donation with pre- and post-operative imaging between 1999 and 2006. The mean follow-up period was 30.2 months (range 12.3-69.6 months). Follow-up imaging evaluation included assessment of the biliary tree, particularly isolated bile ducts draining to and terminating at the cut surface (orphan ducts). Three-dimensional volumetry of the liver remnant was also assessed. RESULTS: After liver donation, 29/42 (69%) participants demonstrated orphan ducts on follow-up imaging (95% confidence interval 52.9% to 82.4%). In those patients with orphan ducts, the main draining ducts were normal in 70% and dilated in 69%. Nearly all right lobe liver donors with orphan ducts had no clinical symptoms on follow-up (28/29); the only liver donor with clinical symptoms on follow-up was subsequently diagnosed with primary biliary cirrhosis. Mean regenerated liver volume was approximately 93%, with mean pre-operative total liver volume of 1552 ml (median 1504 ml, range 1040-2520 ml) and mean post operative total liver volume of 1446 ml (median 1455 ml, range 964-2090 ml). CONCLUSIONS: Orphan ducts are changes that may be seen after liver donation. The presence of these findings in the absence of clinical symptoms or abnormal hepatic chemistries does not require further work-up and should not be considered pathologic. PMID- 29470627 TI - Value of hepatocellular phase imaging after intravenous gadoxetate disodium for assessing hepatic metastases from gastroenteropancreatic neuroendocrine tumors: comparison with other MRI pulse sequences and with extracellular agent. AB - OBJECTIVE: To compare hepatocellular phase imaging after intravenous gadoxetate disodium with other MRI pulse sequences and with extracellular agent for assessing hepatic metastases from gastroenteropancreatic neuroendocrine neoplasms (GEP-NEN). MATERIALS AND METHODS: In this IRB-approved, HIPAA-compliant retrospective study, we included 30 patients (15 women, mean age: 58 years, range 44-77 years) with GEP-NEN metastatic to the liver, who underwent MRI with gadoxetate disodium. Six MRI sequences were reviewed by two radiologists to score tumor-liver interface (TLI) on a 5-point scale, to assess lesion detectability in different liver segments (divided into 3 zones/patient), and to measure lesion size. Contrast-to-noise ratio (CNR) was calculated on each sequence. In 19 patients, lesion size and CNR on dynamic imaging with gadopentetate dimeglumine was compared with hepatocellular phase. Wilcoxon signed-rank test was used to compare TLI scores, lesion size, and median CNR, using Bonferroni correction for multiple testing. Interobserver agreement for TLI was analyzed using Krippendorff's alpha, and for lesion size using concordance correlation coefficient (CCC) and mean relative difference. RESULTS: Hepatocellular phase had the best TLI (mean TLI for reader 1 = 1.2, reader 2 = 1.3) compared to all other sequences (p < 0.0001) with excellent interobserver agreement (Krippendorff's alpha = 1.0), maximum lesion detectability (61/90 zones), highest interobserver agreement for lesion measurement (CCC 0.9875 and smallest mean relative difference - 1.567%), and highest median CNR (31.2, p < 0.008). Hepatocellular phase also had the highest CNR when compared with gadopentetate imaging. CONCLUSION: Hepatocellular phase imaging offers significant advantages for assessment of hepatic metastasis in GEP-NEN, and should be routinely considered for follow-up of these patients. PMID- 29470628 TI - Bladder debris on ultrasound in the emergency department: correlation with urinalysis. AB - PURPOSE: To evaluate the correlation between the presence of bladder debris on ultrasound and urinalysis results in the emergency department setting. METHODS: Adult patients presenting to the emergency department with an ultrasound of the bladder and a urinalysis performed within 24 h of the ultrasound were included in this retrospective study. Two radiologists in consensus evaluated for the presence or absence of debris within the bladder. Urinalysis results were recorded including continuous variables (specific gravity and pH) and categorical variables (presence of occult blood, bilirubin, ketones, glucose, protein, urobilinogen, nitrite, leukocyte esterase, white blood cells, and red blood cells). The presence and absence of white and red blood cells were defined as > 5 cells/high-powered field. To control the experimentwise type I error rate at 0.05, a Bonferroni-corrected significance level of 0.0042 was used to determine significant associations. RESULTS: The presence of bladder debris was associated with the presence of urobilinogen, nitrite, and white blood cells (p = < 0.0001, 0.0005, and 0.0004, respectively). CONCLUSIONS: Bladder debris in the emergency department setting correlates with urinalysis laboratory values suggesting a urinary tract infection. Therefore, the presence of bladder debris should elicit the recommendation of a urinalysis in such a setting. PMID- 29470629 TI - Adding ancillary features to enhancement patterns of hepatocellular carcinoma on gadoxetic acid-enhanced magnetic resonance imaging improves diagnostic performance. AB - PURPOSE: To assess the added value of intratumoral ancillary features to conventional enhancement pattern-based diagnosis of hepatocellular carcinoma (HCC) on gadoxetic acid-enhanced magnetic resonance imaging (MRI). MATERIALS AND METHODS: A total of 773 consecutive patients with surgically resected 773 primary hepatic tumors (699 HCCs, 63 intrahepatic cholangiocarcinomas, and 11 benign nodules) who underwent gadoxetic acid-enhanced MRI were retrospectively identified. Enhancement patterns and three ancillary features of capsule, septum, and T2 spotty hyperintensity were assessed by two radiologists. Performance of enhancement pattern-based diagnosis of HCC was compared to diagnosis of HCC based on enhancement pattern plus ancillary features. RESULTS: Enhancement patterns were positive (arterial diffuse hyperenhancement with washout) for 562 (72.7%) tumors, negative (no arterial hyperenhancement and no washout) for 75 (9.7%), and inconclusive (either no arterial hyperenhancement or no washout) for 136 (17.6%). Capsule was observed in 498 (64.4%) tumors, septum in 521 (67.3%), and T2 spotty hyperintensity in 107 (13.8%). The accuracy and sensitivity of HCC diagnosis was improved significantly after adding at least one ancillary feature compared with enhancement pattern-based diagnosis of HCCs (79.9% vs. 91.1% for accuracy, p < 0.0001 and 79.1% vs. 92.0% for sensitivity, p < 0.0001) with a minor tradeoff in specificity (87.8% vs. 82.4%, p = 0.125). Adding at least two ancillary features improved accuracy (88.1%, p < 0.0001) and sensitivity (88.1%, p < 0.0001) without changing specificity (87.8%, p = 1.0). CONCLUSION: Adding intratumoral ancillary features of capsule, septum and T2 spotty hyperintensity to conventional enhancement patterns on gadoxetic acid-enhanced MRI improved accuracy and sensitivity, while maintaining specificity for HCC diagnosis.

AB - Flavor perception involves both olfactory and gustatory function. In patients with Parkinson's disease (PD), hyposmia is a frequent finding, as well as an increased risk of malnutrition. We performed a pilot study to investigate the relationship between flavor perception and risk of malnutrition in PD patients. 63 PD patients participated to perform an olfactory (Sniffin' Sticks) and gustatory (Taste Strips) task, and a questionnaire to establish nutritional risk (MUST), which includes BMI measurements. The relationship between olfactory and gustatory function and BMI was analyzed using partial correlations, corrected for disease duration, and regression analysis. Patients displayed a high prevalence of hyposmia (68.3%), and a low prevalence (6.3%) of hypogeusia. A small, but significant correlation was found between olfactory function and BMI (r = 0.261, p = 0.038), and not for gustatory function and BMI (r = 0.137, p = 0.284). Hyposmia, and not hypogeusia, may contribute to weight loss in Parkinson's disease, and hence increase the risk of malnutrition. PMID- 29470630 TI - Modified ante situm liver resection without use of cold perfusion nor veno-venous bypass for treatment of hepatic lesions infiltrating the hepatocaval confluence. AB - PURPOSE: Treatment of malignancies invading the hepatic veins/inferior vena cava is a surgical challenge. An ante situm technique allows luxation of the liver in front of the situs to perform tumor resection. Usually, cold perfusion and veno venous bypass are applied. Our experience with modified ante situm resection relying only on total vascular occlusion is reported. METHODS: Retrospective analysis on an almost 15-year experience with ante situm resection without application of cold perfusion or veno-venous bypass RESULTS: The ante situm technique was applied on eight patients. Five individuals were treated due to intrahepatic cholangiocellular cancer and one case each for mixed cholangio /hepatocellular carcinoma, colorectal liver metastasis, and pheochromocytoma. Trisectorectomy (n = 4), left hemihepatectomy, right hepatectomy, atypical resection, or mesohepatectomy (each n = 1) were performed, combined with dissection of suprahepatic/retrohepatic vena cava/hepatic veins. Venous reconstruction was achieved by reimplantation of hepatic veins with/without vascular replacement using allogeneic donor veins or PTFE grafts. Median total vascular occlusion of the liver was 23 min. Severe morbidity occurred in three patients (Dindo-Clavien > 3A). R0 status was achieved in six cases with a median overall survival of 33.5 months. CONCLUSIONS: Ante situm liver resection can be applied without cold perfusion nor veno-venous bypass with acceptable morbidity and mortality. However, this procedure remains challenging even for the experienced hepato-pancreato-biliary surgeon. PMID- 29470633 TI - Feasibility of a novel laparoscopic technique with unidirectional knotless barbed sutures for the primary closure of duodenal ulcer perforation. AB - BACKGROUND: Laparoscopic primary repair is one of the main procedures used for perforated gastric ulcers, and this technique requires reproducible and secure suturing. The aim of this study was to investigate the safety and efficacy of a novel continuous suture method with barbed sutures during laparoscopic repair for perforated peptic ulcers. PATIENTS AND METHODS: Clinical data from 116 consecutive patients undergoing laparoscopic repair for perforated peptic ulcers were collected between November 2009 and October 2015. Continuous suturing with 15-cm-long unidirectional absorbable barbed sutures was used for laparoscopic repair in the study group, termed group V (n = 51). Patients who underwent laparoscopic repair with conventional interrupted sutures were defined as group C (n = 65). The complication and operative data were compared between groups. RESULTS: Although there was no difference between group V and group C in the overall complication rate (15.7% vs. 24.6%; p = 0.259), the complication rate related to suturing was lower (3.9% vs. 15.4%; p = 0.04) in group V. Group V showed rates of 0% for leakage, 2% for intra-abdominal fluid collection, and 2% for stricture; the corresponding rates in group C were 3.1, 7.7, and 4.6%, respectively. Regarding operative data, the total operation time (V vs. C, 87.7 min vs. 131.2 min), total suture time (7.1 min vs. 25.3 min), and suture time per stitch (1.2 min vs. 6.2 min) were significantly shorter in group V than in group C (p < 0.001). CONCLUSION: The use of a continuous suture technique with unidirectional barbed sutures is as safe as the conventional suture technique and allows easier and faster suturing in the repair of perforated peptic ulcers. PMID- 29470634 TI - Detection of Bacterial DNA During the Process of Sake Production Using Sokujo Moto. AB - There are two types of starter cultures used in Japanese rice wine (sake) fermentation, namely, sokujo-moto and yamahai-moto. Analyses of microbiota changes during sake production using yamahai-moto have already been reported. In this study, we analyzed microbiota changes during sake production using sokujo moto. In addition, we sequenced bacterial DNA from the water used in sake production. The Lactobacillus DNA sequences, which are frequently detected during sake production using yamahai-moto, were not detected during sake production using sokujo-moto, indicating that the Lactobacillus DNA detected in sakes made from yamahai-moto is from the fermentation starter. Most bacterial DNA sequences detected in water were not found in the production samples of sake suggesting that these bacteria do not proliferate during sake production. Thus, most of the bacterial DNA sequences detected during the production may be from the bacterial contamination during the production process. PMID- 29470635 TI - Distribution, sources, and toxicity assessment of polycyclic aromatic hydrocarbons in surface soils of a heavy industrial city, Liuzhou, China. AB - As a heavy industrial city, Liuzhou has been facing a serious pollution problem. It is necessary to take steps to control and prevent environmental pollution wherever possible. Surface soil samples were collected from four communities in Liuzhou City, to determine the concentrations, distributions, sources, and toxicity potential of polycyclic aromatic hydrocarbons (PAHs) present. The mean concentrations of total PAHs in the surface soil are 756.43 ng/g for the heavy industrial area, 605.06 ng/g for the industrial area, 481.24 ng/g for the commercial-cum-residential area, and 49.93 ng/g for the rural area. Both the isomer ratio and principal component analyses for the PAHs prove that these pollutants originate mainly from coal, diesel, gasoline, and natural gas combustion. The pollution hierarchies and toxic equivalency factor of BaP prove that the city is subject to heavy pollution caused by industry, transportation, and daily human activities. PMID- 29470636 TI - Migration background and childhood overweight in the Hannover Region in 2010 2014: a population-based secondary data analysis of school entry examinations. AB - : Overweight and obesity constitute a global epidemic with rates that are increasing rapidly in children. The aim of the present study was to examine ethnic differences in the prevalence of overweight in pre-school children in a multicultural context. Data were collected from a compulsory school entry examination in the Hannover Region, Germany (n = 50,716) from 2010 to 2014. The prevalence of overweight (including pre-obesity and obesity status) and obesity was estimated using a German national reference. The migration status of the children was based on the parent's migration history. Multivariable logistic and hierarchical multinomial regression analyses were performed to identify factors associated with the overweight, pre-obesity, and obesity status. The prevalence of overweight was significantly higher among migrant children (12.7%) than among the non-migrant children (6.9%). After adjusting for socioeconomic and child development variables, migration background was strongly associated with weight status. The Turkish migrant children showed the highest odds of being pre-obesity (OR 2.05, 95%CI 1.7-2.56) and obesity (OR 2.09, 95%CI 1.67-2.77) compared to non migrant children. CONCLUSION: Ethnic and social inequalities exist in childhood overweight among pre-school children in the Hannover Region. Thus, appropriate interventions targeting high-risk migrant groups are needed. What is Known: * The current trend of prevalence rates in Germany for overweight and obesity of pre school children is becoming stable. * Prevalence of overweight and obesity is clearly higher among migrant children than among non-migrant children. What is New: * This article reveals ethnic variance among different migrant groups. * Turkish migrant children have a higher rate of prevalence even compared to other migrant groups. * Length of child day care attendance fails to exert a strong influence on overweight after adjusting for socio-economic and child development variables. PMID- 29470637 TI - A higher association of medial collateral ligament injury of the knee in pronation injuries of the ankle. AB - INTRODUCTION: To evaluate the prevalence of medial collateral ligament (MCL) injury of the knee among ankle-fracture patients and to determine the risk factors associated with MCL injury in this patient group. MATERIALS AND METHODS: 303 patients (303 affected ankles) who underwent surgical treatment for an ankle fracture were assessed. Supination versus pronation injury, Danis-Weber classification, age, sex, body mass index (BMI), limb dominance, and mechanism of injury were reviewed to identify factors related to MCL injury. RESULTS: Prevalence of MCL injury of the knee among the total number of patients with an ankle fracture was 3.96% (12 out of 303 injuries). Multivariable logistic and linear regression analysis with adjustment of possible confounding factors confirmed that female sex and pronation injury were associated significantly (p < 0.05) with MCL injury. CONCLUSIONS: The prevalence of MCL injury among females and the pronation type of ankle injury was 8.19% (10 out of 122 females) and 10.75% (10 out of 93 pronation injuries), respectively. More careful physical examination of the knee joint is strongly recommended in patients with ankle fractures, especially if the patient is female or the ankle-fracture pattern corresponds to the pronation type of injury. PMID- 29470638 TI - Long-term effects of low-dose mouse liver irradiation involve ultrastructural and biochemical changes in hepatocytes that depend on lipid metabolism. AB - The aim of the study was to investigate long-term effects of radiation on the (ultra)structure and function of the liver in mice. The experiments were conducted on wild-type C57BL/6J and apolipoprotein E knock-out (ApoE-/-) male mice which received a single dose (2 or 8 Gy) of X-rays to the heart with simultaneous exposure of liver to low doses (no more than 30 and 120 mGy, respectively). Livers were collected for analysis 60 weeks after irradiation and used for morphological, ultrastructural, and biochemical studies. The results show increased damage to mitochondrial ultrastructure and lipid deposition in hepatocytes of irradiated animals as compared to non-irradiated controls. Stronger radiation-related effects were noted in ApoE-/- mice than wild-type animals. In contrast, radiation-related changes in the activity of lysosomal hydrolases, including acid phosphatase, beta-glucuronidase, N-acetyl-beta-D hexosaminidase, beta-galactosidase, and alpha-glucosidase, were observed in wild type but not in ApoE-deficient mice, which together with ultrastructural picture suggests a higher activity of autophagy in ApoE-proficient animals. Irradiation caused a reduction of plasma markers of liver damage in wild-type mice, while an increased level of hepatic lipase was observed in plasma of ApoE-deficient mice, which collectively indicates a higher resistance of hepatocytes from ApoE proficient animals to radiation-mediated damage. In conclusion, liver dysfunctions were observed as late effects of irradiation with an apparent association with malfunction of lipid metabolism. PMID- 29470639 TI - Arabinogalactan proteins and their sugar chains: functions in plant reproduction, research methods, and biosynthesis. AB - The arabinogalactan protein (AGP) family is one of the most complex protein families and is ubiquitous in the plant kingdom. Moreover, it has been demonstrated to play various roles during plant reproduction. A typical AGP contains a hydroxyproline-rich core protein with high heterogeneity and varying numbers of polysaccharide side chains. However, the functions of the polysaccharide components (i.e. AG sugar chains) remain largely unknown due to the general difficulties associated with studying sugar chains in glycobiology. In recent years, methodological breakthroughs have resulted in substantial progress in AGP research. Here, we summarise the multiple roles of AGPs during plant gametophyte development and male-female communication, with a focus on recent advances. In addition, we discuss the analytical tools used in AGP research, and the biosynthesis and function of AG sugar chains. A comprehensive understanding of the AGP family will help clarify the mechanisms precisely controlling reproductive processes.

AB - PURPOSES: To evaluate the feasibility of simultaneous quantification of liver iron concentration (LIC) and fat fraction (FF) using water-fat separation and quantitative susceptibility mapping (QSM). METHODS: Forty-five patients suspected of liver iron overload (LIO) were included. A volumetric interpolated breath-hold examination sequence for QSM and FF, a fat-saturated gradient echo sequence for R2*, a spin echo sequence for LIC measurements and MRS analyses for FF (FF-MRS) were performed. Magnetic susceptibility and FF were calculated using a water-fat separation method (FF-MRI). Correlation and receiver operating characteristic analyses were performed. RESULTS: Magnetic susceptibility showed strong correlation with LIC (rs=0.918). The optimal susceptibility cut-off values were 0.34, 0.63, 1.29 and 2.23 ppm corresponding to LIC thresholds of 1.8, 3.2, 7.0 and 15.0 mg/g dry weight. The area under the curve (AUC) were 0.948, 0.970, 1 and 1, respectively. No difference in AUC was found between susceptibility and R2* at all LIC thresholds. Correlation was found between FF-MRI and FF-MRS (R2=0.910). CONCLUSIONS: QSM has a high diagnostic performance for LIC quantification, similar to that of R2*. FF-MRI provides simultaneous fat quantification. Findings suggest QSM in combination with water-fat separation has potential value for evaluating LIO, especially in cases with coexisting steatosis. KEY POINTS: * Magnetic susceptibility showed strong correlation with LIC (r s =0.918). * QSM showed high diagnostic performance for LIC, similar to that of R 2* . * Simultaneously estimated FF-MRI showed strong correlation with MR-Spectroscopy based FF (R 2 =0.910). * QSM combining water-fat separation has quantitative value for LIO with coexisted steatosis. PMID- 29470642 TI - Real-World Switching to Riociguat: Management and Practicalities in Patients with PAH and CTEPH. AB - PURPOSE: A proportion of patients with pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) do not achieve treatment goals or experience side effects on their current therapy. In such cases, switching patients to a new drug while discontinuing the first may be a viable and appropriate treatment option. CAPTURE was designed to investigate how physicians manage the switching of patients to riociguat in real-world clinical practice. Observations from the study were used to assess whether recommendations in the riociguat prescribing information are reflected in clinical practice. METHODS: CAPTURE was an international, multicenter, uncontrolled, retrospective chart review that collected data from patients with PAH or inoperable or persistent/recurrent CTEPH who switched to riociguat from another pulmonary hypertension (PH)-targeted medical therapy. The primary objective of the study was to understand the procedure undertaken in real-world clinical practice for patients switching to riociguat. RESULTS: Of 127 patients screened, 125 were enrolled in CAPTURE. The majority of patients switched from a phosphodiesterase type 5 inhibitor (PDE5i) to riociguat and the most common reason for switching was lack of efficacy. Physicians were already using the recommended treatment free period when switching patients to riociguat from sildenafil, but a slightly longer period than recommended for tadalafil. In line with the contraindication, the majority of patients did not receive riociguat and PDE5i therapy concomitantly. Physicians also followed the recommended dose-adjustment procedure for riociguat. CONCLUSION: Switching to riociguat from another PH-targeted therapy may be feasible in real-world clinical practice in the context of the current recommendations. PMID- 29470643 TI - Diurnal, semidiurnal, and fortnightly tidal components in orthotidal proglacial rivers. AB - The orthotidal rivers are a new concept referring to inland rivers influenced by gravitational tides through the groundwater tides. "Orthotidal signals" is intended to describe tidal signals found in inland streamwaters (with no oceanic input); these tidal signals were locally generated and then exported into streamwaters. Here, we show that orthotidal signals can be found in proglacial rivers due to the gravitational tides affecting the glaciers and their surrounding areas. The gravitational tides act on glacier through earth and atmospheric tides, while the subglacial water is affected in a manner similar to the groundwater tides. We used the wavelet analysis in order to find tidally affected streamwaters. T_TIDE analyses were performed for discovering the tidal constituents. Tidal components with 0.95 confidence level are as follows: O1, PI1, P1, S1, K1, PSI1, M2, T2, S2, K2, and MSf. The amplitude of the diurnal tidal constituents is strongly influenced by the daily thermal cycle. The average amplitude of the semidiurnal tidal constituents is less altered and ranges from 0.0007 to 0.0969 m. The lunisolar synodic fortnightly oscillation, found in the time series of the studied river gauges, is a useful signal for detecting orthotidal rivers when using noisier data. The knowledge of the orthotidal oscillations is useful for modeling fine resolution changes in rivers. PMID- 29470644 TI - Two genes encoding GH10 xylanases are essential for the virulence of the oomycete plant pathogen Phytophthora parasitica. AB - Plant cell walls are pivotal battlegrounds between microbial pathogens and their hosts. To penetrate the cell wall and thereby to facilitate infection, microbial pathogens are equipped with a wide array of cell wall-degrading enzymes to depolymerize the polysaccharides in the cell wall. However, many of these enzymes and their role in the pathogenesis of microbial pathogens are not characterized, especially those from Oomycetes. In this study, we analyzed the function of four putative endo-beta-1,4-xylanase-encoding genes (ppxyn1-ppxyn4) from Phytophthora parasitica, an oomycete plant pathogen known to cause severe disease in a wide variety of plant species. All four genes belong to the glycoside hydrolase family 10 (GH10). Recombinant proteins of ppxyn1, ppxyn2, and ppxyn4 obtained from the yeast Pichia pastoris showed degrading activities toward birch wood xylan, but they behaved differently in terms of the conditions for optimal activity, thermostability, and durability. Quantitative RT-PCR revealed upregulated expression of all four genes, especially ppxyn1 and ppxyn2, during plant infection. In contrast, ppxyn3 was highly expressed in cysts and its close homolog, ppxyn4, in germinating cysts. To uncover the role of ppxyn1 and ppxyn2 in the pathogenesis of P. parasitica, we generated silencing transformants for these two genes by double-stranded RNA-mediated gene silencing. Silencing ppxyn1 and ppxyn2 reduced the virulence of P. parasitica toward tobacco (Nicotiana benthamiana) and tomato plants. These results demonstrate the crucial role of xylanase-encoding ppxyn1 and ppxyn2 in the infection process of P. parasitica.

AB - Phosphatidylinositol 3-kinase-related kinases (PIKKs), are structurally related to phosphatidylinositol 3-kinase (lipid kinase), but possess protein kinase activities. PIKKs include ATM, ATR, DNA-PK, mTOR and SMG1, key regulators of cell proliferation and genome maintenance. TRRAP, which is devoid of protein kinase activity, is the sixth member of the PIKK family. PIKK family members are gigantic proteins in the range of 300-500 kDa. It has become apparent in the last decade that the stability or maturation of the PIKK family members depends on a molecular chaperone called the Tel2-Tti1-Tti2 (TTT) complex. Several lines of evidence have established a model in which TTT connects to the Hsp90 chaperone through the Rvb1-Rvb2-Tah1-Pih1 (R2TP) complex in mammalian and yeast cells. However, recent studies of yeast cells indicate that TTT is able to form different complexes. These observations raise a possibility that several different mechanisms regulate TTT-mediated protein stability of PIKKs.

AB - Sleep apnea is a prevalent respiratory disease characterized by periodic cessation of breathing during sleep causing intermittent hypoxia (IH). Sleep apnea patients and rodents exposed to IH exhibit elevated sympathetic nerve activity and hypertension. A heightened carotid body (CB) chemoreflex has been implicated in causing autonomic abnormalities in IH-treated rodents and in sleep apnea patients. The purpose of this article is to review the emerging evidence showing that interactions between reactive oxygen species (ROS) and gaseous transmitters as a mechanism cause hyperactive CB by IH. Rodents treated with IH exhibit markedly elevated ROS in the CB, which is due to transcriptional upregulation of pro-oxidant enzymes by hypoxia-inducible factor (HIF)-1 and insufficient transcriptional regulation of anti-oxidant enzymes by HIF-2. ROS, in turn, increases cystathionine gamma-lyase (CSE)-dependent H2S production in the CB. Blockade of H2S synthesis prevents IH-evoked CB activation. However, the effects of ROS on H2S production are not due to direct effects on CSE enzyme activity but rather due to inactivation of heme oxygenase-2 (HO-2), a carbon monoxide (CO) producing enzyme. CO inhibits H2S production through inactivation of CSE by PKG-dependent phosphorylation. During IH, reduced CO production resulting from inactivation of HO-2 by ROS releases the inhibition of CO on CSE thereby increasing H2S. Inhibiting H2S synthesis prevented IH-evoked sympathetic activation and hypertension. PMID- 29470647 TI - Dopaminergic innervation and modulation of hippocampal networks. AB - The catecholamine dopamine plays an important role in hippocampus-dependent plasticity and related learning and memory processes. Dopamine secretion in the hippocampus is activated by, e.g., salient or novel stimuli, thereby helping to establish and to stabilize hippocampus-dependent memories. Disturbed dopaminergic function in the hippocampus leads to severe pathophysiological conditions. While the role and importance of dopaminergic modulation of hippocampal networks have been unequivocally proven, there is still a lack of detailed molecular and cellular mechanistic understanding of how dopamine orchestrates these hippocampal processes. In this chapter of the special issue "Hippocampal structure and function," we will discuss the current understanding of dopaminergic modulation of basal synaptic transmission and long-lasting, activity-dependent potentiation or depression.

PMID- 29470649 TI - Structural arrangement of the intrinsic muscles of the tongue and their relationships with the extrinsic muscles. AB - The tongue is a dense muscular organ, in which the muscles are arranged in a confusing pattern. The intrinsic muscles were gross anatomically investigated in 25 cadavers to clarify their configuration. The superior longitudinal muscle (SLm) ran beneath the dorsal mucosa and was divided into bundles by the other muscles passing through it to the dorsum. The external bundle of the styloglossus, with the palatoglossus, coursed externally to the hyoglossus. Their fibers spread beneath the SLm or attached to the apex and the inferior longitudinal muscle (ILm) ascended from the root and joined them. The genioglossus and the anterior part of the hyoglossus extended internally and externally to the ILm, respectively, to the dorsum, and the vertical muscle was sandwiched between them. The transverse muscle passed laterally from the lingual septum. The fibers of the posterior part of the hyoglossus converged to the root and spread beneath the SLm. The intersections between these vertical and transverse fibers divided one another into bundles or lamellae. The middle bundle of the styloglossus, passing between the two parts of the hyoglossus, was divided into slips by the intersection with the genioglossus. The internal bundle of the styloglossus, with the glossopharyngeus, descended internally to the posterior part to the root. The findings indicate that the intrinsic and extrinsic muscles of the tongue are not independent groups, and their fibers form a three dimensional latticework. Each muscle contains numerous bundles or lamellae as functional units that can act separately or cooperate across the muscles. PMID- 29470651 TI - Prediction of surgical site infection in spine surgery from tests of nasal MRSA colonization and drain tip culture. AB - PURPOSE: MRSA is an organism that is a possible risk factor for postoperative SSI. The purpose of the study was to examine relationships among surgical site infection (SSI) after spinal surgery, nasal methicillin-resistant staphylococcus aureus (MRSA) colonization, and wound drain culture results. METHODS: The subjects were 132 patients who underwent spinal instrumentation surgery. A preoperative nasal swab was used to check for the presence of MRSA colonization, and a wound drain tip culture was performed for detection of SSI. Data from culture studies using nasal samples and those from the distal tip of the wound drain were used for analysis. RESULTS: Five patients (3.8%) had nasal MRSA, 17 (13%) had positive drain tip cultures, 15 (11%) had SSIs, and 10 (8%) had SSIs with MRSA. Patients with nasal MRSA had a higher rate of detection of bacteria in the drain tip culture (40 vs. 19%, p = 0.065), and the SSI rate was significantly higher in patients with a positive drain tip culture (33 vs. 10%, p = 0.012). The total SSI rate differed significantly between patients with and without nasal MRSA (40 vs. 10%, p = 0.039); however, the SSI with MRSA rate did not differ significantly between these groups. CONCLUSION: MRSA carriers were not necessarily associated with MRSA infection, but were related to a positive drain tip culture and SSI, which might be due to endogenous skin bacteria. Therefore, possible SSI should be considered in patients with nasal MRSA colonization or bacteria detected in a drain tip culture. PMID- 29470650 TI - Management of knee dislocation prior to ligament reconstruction: What is the current evidence? Update of a universal treatment algorithm. AB - Traumatic knee dislocation is a rare but potentially limb-threatening injury. Thus proper initial diagnosis and treatment up to final ligament reconstruction are extremely important and a precondition to successful outcomes. Reports suggest that evidence-based systematic approaches lead to better results. Because of the complexity of this injury and the inhomogeneity of related literature, there are still various controversies and knowledge gaps regarding decision making and step-sequencing in the treatment of acute multi-ligament knee injuries and knee dislocations. The use of ankle-brachial index, routine or selective angiography, braces, joint-spanning or dynamic external fixation, and the necessity of initial ligament re-fixation during acute surgery constitutes current topics of a scholarly debate. The aim of this article was to provide a comprehensive literature review bringing light into some important aspects about the initial treatment of knee dislocation (vascular injury, neural injury, immobilization techniques) and finally develop an accurate data-based universal algorithm, enabling attending physicians to become more acquainted with the management of acute knee dislocation.

AB - Transformation of natural polymers to three-dimensional (3D) scaffolds for biomedical applications faces a number of challenges, viz., solubility, stability (mechanical and thermal), strength, biocompatibility, and biodegradability. Hence, intensive research on suitable agents to provide the requisite properties has been initiated at the global level. In the present study, an attempt was made to engineer chitosan and collagen macromolecules using sebacic acid, and further evaluation of the mechanical stability and biocompatible property of the engineered scaffold material was done. A 3D scaffold material was prepared using chitosan at 1.0% (w/v) and sebacic acid at 0.2% (w/v); similarly, collagen at 0.5% (w/v) and sebacic acid at 0.2% (w/v) were prepared individually by freeze drying technique. Analysis revealed that the engineered scaffolds displayed an appreciable mechanical strength and, in addition, were found to be biocompatible to NIH 3T3 fibroblast cells. Studies on the chemistry behind the interaction and the characteristics of the cross-linked scaffold materials suggested that non covalent interactions play a major role in deciding the property of the said polymer materials. The prepared scaffold was suitable for tissue engineering application as a wound dressing material. PMID- 29470653 TI - [Lymph-node-positive penile cancer : Management and systemic therapy]. AB - Cancer-specific survival in men with penile cancer depends foremost on regional lymphatic metastasis and its extent. Patients with limited inguinal lymph node metastases have a 5-year survival of up to 80%. However, those with pelvic lymph node metastases and/or systemic disease have a 5-year survival prognosis of only 0-33%. In any case, in patients with regional lymph node metastases multimodal treatment with complete lymphadenectomy and adjuvant chemotherapy is indicated. PMID- 29470654 TI - [Molecular characterization of penile cancer : Literature review of new prognostic markers and potential therapeutic targets]. AB - Squamous cell carcinoma of the penis (SCCP) is a rare cancer type in Western industrialized nations; nevertheless, it shows an aggressive course of disease in advanced tumor stages with accordantly high recurrence and progression rates. While molecular biomarkers are not established in clinical routine for the management of SCCP patients yet, the accordant unmet need is enormous, as adequate biomarkers would be meaningful for prognostic determination, planning of modality and extent of primary therapy, indication for inguinal lymph node resection, adjuvant treatment, and as potential targets for specific systemic treatment. SCCP regularly develops from a precursor lesion. In this regard, human papillomavirus (HPV)-dependent and -independent pathways are differentiated. The potential for specific target therapy options is mainly based on the decoding of genetic and epigenetic signatures of distinct molecular pathways. In order to develop targeted and personalized treatment strategies based on molecular pathways, an increase in translational research in large multi-institutional collaborations must be promoted. This review article aims to summarize the current status of research concerning molecular changes related to SCCP under separate consideration of prognostic molecular markers, on the one hand, and biomarkers considered potential therapeutic targets, on the other hand. In addition, previous research activities of our own working group on this topic are briefly described. PMID- 29470655 TI - [Lymph node management of cN0 penile cancer]. AB - In penile cancer, lymph node metastasis is the main known prognostic factor affecting patients' survival. Early inguinal lymph node dissection or the resection of clinically occult lymph node metastases improves survival compared with removal when the metastases become clinically apparent. Micrometastatic lymph node involvement is undetectable by current imaging modalities. Nomograms based on clinical and histopathological tumor characteristics are unreliable in predicting lymph node involvement. Consequently, in penile cancer patients with clinically normal inguinal lymph nodes (cN0) and a tumor stage >=pT1, G2 surgical lymph node exploration is recommended. Radical inguinal lymphadenectomy is no longer recommended because of its invasiveness and high complication rate. Modified lymphadenectomy and dynamic sentinel lymph node surgery allow the detection of lymph node-positive patients with sufficient certainty. Thereby, the sentinel lymph node approach offers the least invasiveness and high sensitivity. Extended inguinal lymphadenectomy is still recommended in the case of positive nodes. PMID- 29470656 TI - Industrial point source CO2 emission strength estimation with aircraft measurements and dispersion modelling. AB - CO2 remains the greenhouse gas that contributes most to anthropogenic global warming, and the evaluation of its emissions is of major interest to both research and regulatory purposes. Emission inventories generally provide quite reliable estimates of CO2 emissions. However, because of intrinsic uncertainties associated with these estimates, it is of great importance to validate emission inventories against independent estimates. This paper describes an integrated approach combining aircraft measurements and a puff dispersion modelling framework by considering a CO2 industrial point source, located in Biganos, France. CO2 density measurements were obtained by applying the mass balance method, while CO2 emission estimates were derived by implementing the CALMET/CALPUFF model chain. For the latter, three meteorological initializations were used: (i) WRF-modelled outputs initialized by ECMWF reanalyses; (ii) WRF modelled outputs initialized by CFSR reanalyses and (iii) local in situ observations. Governmental inventorial data were used as reference for all applications. The strengths and weaknesses of the different approaches and how they affect emission estimation uncertainty were investigated. The mass balance based on aircraft measurements was quite succesful in capturing the point source emission strength (at worst with a 16% bias), while the accuracy of the dispersion modelling, markedly when using ECMWF initialization through the WRF model, was only slightly lower (estimation with an 18% bias). The analysis will help in highlighting some methodological best practices that can be used as guidelines for future experiments. PMID- 29470657 TI - Characterization of crystalline cellulose of jute reinforced poly (vinyl alcohol) (PVA) biocomposite film for potential biomedical applications. AB - Cellulose crystals (CC) were chemically derived from jute by alkali treatment, bleaching and subsequent hydrolysis with 40 % sulfuric acid. Infrared spectroscopy (FT-IR) suggested sufficient removal of lignin and hemicellulose from the raw jute and scanning electron microscopy (SEM), and X-ray diffraction (XRD) studies demonstrated the preparation of microcrystalline cellulose. CC reinforced polyvinyl alcohol (PVA) composite was prepared by solution casting method under laminar flow. In order to maintain uniform dispersion of 3-15 % (w/w) of the CC in the composite N, N dimethylformamide (DMF) was used as a dispersant. FT-IR, XRD, SEM, thermogravimetric analysis (TG, DTG and DTA) and thermomechanical analyses (TMA) were used to characterize the CC and the composites. The study of tensile properties showed that tensile strength (TS) and modulus (TM) increase with increasing CC content up to 9 % and then decrease with the addition of a high content of CC (above 9 %) because of the aggregation of CCs in the composite. The highest TS (43.9 MPa) and TM (2,190 MPa) have been shown to be the composite prepared with 9 % CC and the lowest to be from pure PVA film 17.1 and 1470 MPa. In addition, the composites have showed no cytotoxicity that can also prohibit microbial growth and; hence, it can be a potential material for biomedical applications such as wound healing accelerators. PMID- 29470658 TI - Current Status of Potential Therapies for IgE-Mediated Food Allergy. AB - PURPOSE OF REVIEW: The goal of this review is to provide the reader with an updated summary of published trial data regarding the use of oral immunotherapy (OIT), sublingual immunotherapy (SLIT), and epicutaneous immunotherapy (EPIT) for treatment of IgE-mediated food allergies. RECENT FINDINGS: Data from phase 2 trials for treatment of peanut allergy with OIT and EPIT reveal an increase in the threshold of reactivity for peanut-allergic children. Compared to EPIT, OIT promotes a greater increase in the threshold of reactivity; however, adverse events are more common with OIT. OIT, EPIT, and SLIT appear to modulate the immune response for some food-allergic individuals. Data regarding utility for treatment of food allergies regardless of modality is limited to few foods, as is investigation into treatment of food-allergic infants, young children, and adults. Future trials are likely to focus on young children, food allergies other than peanut, and treatment of multifood-allergic individuals. PMID- 29470659 TI - Impact of Particulate Air Pollution on Cardiovascular Health. AB - PURPOSE OF REVIEW: Air pollution is established as an independent risk factor for cardiovascular diseases (CVDs). Ambient particulate matter (PM), a principal component of air pollutant, has been considered as a main culprit of the adverse effects of air pollution on human health. RECENT FINDINGS: Extensive epidemiological and toxicological studies have demonstrated particulate air pollution is positively associated with the development of CVDs. Short-term PM exposure can trigger acute cardiovascular events while long-term exposure over years augments cardiovascular risk to an even greater extent and can reduce life expectancy by a few years. Inhalation of PM affects heart rate variability, blood pressure, vascular tone, blood coagulability, and the progression of atherosclerosis. The potential molecular mechanisms of PM-caused CVDs include direct toxicity to the cardiovascular system or indirect injury by inducing systemic inflammation and oxidative stress in circulation. This review mainly focuses on the acute and chronic effects of ambient PM exposure on the development of cardiovascular diseases and the possible mechanisms for PM-induced increases in cardiovascular morbidity and mortality. Additionally, we summarized some appropriate interventions to attenuate PM air pollution-induced cardiovascular adverse effects, which may promote great benefits to public health. PMID- 29470660 TI - The Effect of Inhalant Organic Dust on Bone Health. AB - PURPOSE OF REVIEW: Agriculture remains a major economic sector globally, and workers experience high rates of chronic inflammatory lung and musculoskeletal diseases. Whereas obstructive pulmonary diseases are known risk factors for bone loss, the underlying relationship between lung inflammation and bone health is not well known. RECENT FINDINGS: An agriculture organic dust extract inhalation animal model has recently linked lung injury-induced inflammation to systemic bone loss. This process is dependent upon lipopolysaccharide and the toll-like receptor 4 (TLR4) signaling pathway. Downstream systemic interleukin-6 is a key mediator that subsequently activates osteoclastogenesis. Age is a host factor that impacted bone disease with younger mice demonstrating increased susceptibility to bone loss following inhalant exposures as compared to older mice. Supplemental dietary vitamin D was shown to prevent organic dust-induced bone loss, but not lung disease, in animals. Recent animal studies provide new mechanistic insight into the lung-bone inflammatory axis. Host factors, diet, and lipopolysaccharide/TLR4 signaling pathways play a significant role in explaining how inhalant organic dust exposures impact bone health. These investigations might lead to specific targeted therapeutic approaches. PMID- 29470661 TI - Granulomatous-Lymphocytic Interstitial Lung Disease in 22q11.2 Deletion Syndrome: a Case Report and Literature Review. AB - PURPOSE OF REVIEW: Granulomatous-lymphocytic interstitial lung disease (GLILD) has classically been associated with common variable immune deficiency (CVID), but is increasingly being reported in other immunodeficiencies. We describe the second reported case of GLILD in a patient with 22q11.2 deletion syndrome (22q11.2DS) and review the recent literature surrounding GLILD. RECENT FINDINGS: GLILD is characterized by granulomata and lymphoproliferation. Consensus statements and retrospective and case-control studies have better elucidated the clinicopathological and radiographic manifestations of GLILD, allowing for its differentiation from similar conditions like sarcoidosis. Gaps of knowledge remain, however, particularly regarding optimal management strategies. Combination therapies targeting T and B cell populations have recently shown favorable results. GLILD is associated with poorer outcomes in CVID. Its recognition as a rare complication of 22q11.2DS and other immunodeficiencies therefore has important therapeutic and prognostic implications. Additional research is needed to better understand the natural history and pathogenesis of GLILD and to develop evidence-based practice guidelines.

AB - In my 2010 review, I addressed conventional water analysis and biosensing of organic pollutants in Japan between 1960s and 2000s. It is now timely to reexamine current analytical and biomonitoring approaches in view of the new challenges in assessing pollution, particularly in closed water bodies, as pollutants tend to accumulate in these endorheic basins. In the present review series, I presented current water environment and its microbial biosensors. In this part, I presented current data of the water quality of these water bodies in Japan and established the need to further develop microbial biosensor technologies to address and monitor water quality here.

AB - The identification and quantification of molecules involved in bacterial communication are major prerequisites for the understanding of interspecies interactions at the molecular level. We developed a procedure allowing the determination of 2-heptyl-4(1H)-quinolone (HHQ) and 2-heptyl-3-hydroxy-4(1H) quinolone (PQS) and the virulence factor pyocyanin (PYO) formed by the Gram negative bacterium Pseudomonas aeruginosa. The method is based on dispersive liquid-liquid microextraction from small supernatant volumes (below 10 MUL) followed by quantitative matrix-assisted laser desorption/ionization (MALDI) mass spectrometry (MS). The use of ionic liquid matrix led to a lowered limit of detection for pyocyanin and, due to suppression of matrix background signals, easy to interpret mass spectra compared to crystalline matrices. Using an isotope labeled pyocyanin standard synthesized in small-scale synthesis, quantitative analysis spanning approximately one order of magnitude (0.5 to 250 fmol) was feasible. The method was successfully applied to the detection of the signaling molecules PQS and HHQ in cultures of P. aeruginosa strains isolated from sputum of cystic fibrosis patients and allowed a highly sensitive quantification of PYO from these cultures. Hence, the developed method bears the potential to be used for screening purposes in clinical settings and will help to decipher the molecular basis of bacterial communication.

PMID- 29470664 TI - Toward miniaturized analysis of chemical identity and purity of radiopharmaceuticals via microchip electrophoresis. AB - Miniaturized synthesis of positron emission tomography (PET) tracers is poised to offer numerous advantages including reduced tracer production costs and increased availability of diverse tracers. While many steps of the tracer production process have been miniaturized, there has been relatively little development of microscale systems for the quality control (QC) testing process that is required by regulatory agencies to ensure purity, identity, and biological safety of the radiotracer before use in human subjects. Every batch must be tested, and in contrast with ordinary pharmaceuticals, the whole set of tests of radiopharmaceuticals must be completed within a short-period of time to minimize losses due to radioactive decay. By replacing conventional techniques with microscale analytical ones, it may be possible to significantly reduce instrument cost, conserve lab space, shorten analysis times, and streamline this aspect of PET tracer production. We focus in this work on miniaturizing the subset of QC tests for chemical identity and purity. These tests generally require high resolution chromatographic separation prior to detection to enable the approach to be applied to many different tracers (and their impurities), and have not yet, to the best of our knowledge, been tackled in microfluidic systems. Toward this end, we previously explored the feasibility of using the technique of capillary electrophoresis (CE) as a replacement for the "gold standard" approach of using high-performance liquid chromatography (HPLC) since CE offers similar separating power, flexibility, and sensitivity, but can readily be implemented in a microchip format. Using a conventional CE system, we previously demonstrated the successful separation of non-radioactive version of a clinical PET tracer, 3' deoxy-3'-fluorothymidine (FLT), from its known by-products, and the separation of the PET tracer 1-(2'-deoxy-2'-fluoro-beta-D-arabinofuranosyl)-cytosine (D-FAC) from its alpha-isomer, with sensitivity nearly as good as HPLC. Building on this feasibility study, in this paper, we describe the first effort to miniaturize the chemical identity and purity tests by using microchip electrophoresis (MCE). The fully automated proof-of-concept system comprises a chip for sample injection, a separation capillary, and an optical detection chip. Using the same model compound (FLT and its known by-products), we demonstrate that samples can be injected, separated, and detected, and show the potential to match the performance of HPLC. Addition of a radiation detector in the future would enable analysis of radiochemical identity and purity in the same device. We envision that eventually this MCE method could be combined with other miniaturized QC tests into a compact integrated system for automated routine QC testing of radiopharmaceuticals in the future. Graphical abstract Miniaturized quality control (QC) testing of batches of radiopharmaceuticals via microfluidic analysis. The proof-of-concept hybrid microchip electrophoresis (MCE) device demonstrated the feasibility of achieving comparable performance to conventional analytical instruments (HPLC or CE) for chemical purity testing. PMID- 29470665 TI - A new method for water quality assessment: by harmony degree equation. AB - Water quality assessment is an important basic work in the development, utilization, management, and protection of water resources, and also a prerequisite for water safety. In this paper, the harmony degree equation (HDE) was introduced into the research of water quality assessment, and a new method for water quality assessment was proposed according to the HDE: by harmony degree equation (WQA-HDE). First of all, the calculation steps and ideas of this method were described in detail, and then, this method with some other important methods of water quality assessment (single factor assessment method, mean-type comprehensive index assessment method, and multi-level gray correlation assessment method) were used to assess the water quality of the Shaying River (the largest tributary of the Huaihe in China). For this purpose, 2 years (2013 2014) dataset of nine water quality variables covering seven monitoring sites, and approximately 189 observations were used to compare and analyze the characteristics and advantages of the new method. The results showed that the calculation steps of WQA-HDE are similar to the comprehensive assessment method, and WQA-HDE is more operational comparing with the results of other water quality assessment methods. In addition, this new method shows good flexibility by setting the judgment criteria value HD0 of water quality; when HD0 = 0.8, the results are closer to reality, and more realistic and reliable. Particularly, when HD0 = 1, the results of WQA-HDE are consistent with the single factor assessment method, both methods are subject to the most stringent "one vote veto" judgment condition. So, WQA-HDE is a composite method that combines the single factor assessment and comprehensive assessment. This research not only broadens the research field of theoretical method system of harmony theory but also promotes the unity of water quality assessment method and can be used for reference in other comprehensive assessment. PMID- 29470666 TI - The effect of polymer and CaCl2 concentrations on the sulfasalazine release from alginate-N,O-carboxymethyl chitosan beads. AB - In this study, pH-sensitive blended polymeric beads were prepared by ionic gelation of mixed alginate and N,O-carboxymethyl chitosan (NOCC) solutions in aqueous media containing calcium chloride. To prepare drug-loaded beads, sulfasalazine (SA) as a model drug was added to the initial aqueous polymer solution. These beads were characterized and evaluated in vitro as potential carriers for colon-specific drug delivery. A 32 full factorial experimental design was employed to evaluate the effect of polymer and CaCl2 concentrations on swelling and drug release behavior of the beads in simulated gastrointestinal tract fluid. It was found that the rate of swelling and drug release decreased significantly with increasing polymer and CaCl2 concentrations, but polymer concentration was more effective than CaCl2 concentration. The beads prepared using 4.5% polymer concentration and 4% CaCl2 concentration retained approximately 60% of the loaded drug before approaching the simulated colonic fluid. Based on the results, the alginate-NOCC beads prepared with high polymer concentration could be potentially suitable polymeric carriers for colon-specific delivery of SA. PMID- 29470667 TI - Microhardness of bi-antibiotic-eluting bone cement scaffolds. AB - Bi-antibiotic-impregnated bone cements (BIBCs) are widely used in orthopaedics as a prophylactic agent (depot) to address post-surgical infections. Although hardness is widely considered a viable index to measure the integrity of the cement structure, there are few specific studies involving changes in hardness characteristics of BIBCs post elution of high doses of two widely used antibiotics: tobramycin and gentamicin. Increased doses of antibiotics and increased duration of elution may also decrease the hardness of polymethyl methacrylate (PMMA) bone cement, thus increasing the chances of shattering, scratching, and deformation.In this project, we have investigated the changes in surface hardness of five different antibiotic-loaded specimens: 0.5 g tobramycin and 0.5 g gentamicin together, 1 g tobramycin, 1 g gentamicin, 5 g tobramycin and 5 g gentamicin together, and 10 g tobramycin (each added to 40 g of PMMA), post elution for various time periods (1, 3, and 21 days). The effect of hydration on the hardness of bone cement was studied to replicate in vivo conditions. The micro-indentation tester (Buehler m5103) was utilized to determine if the increased antibiotic loads would compromise the integrity of the bone cement matrix.The results demonstrated that the amount of drug initially incorporated determined the hardness of the cement post elution. As compared to the control (no antibiotic), specimens containing 1 and 10 g of antibiotic exhibited over 50% and 73% decrease in hardness, respectively. The different treatment durations (post 1 day) as well as the hydration conditions had insignificant effect on the hardness of the cement. PMID- 29470668 TI - Indoor Environmental Interventions and their Effect on Asthma Outcomes. AB - PURPOSE OF REVIEW: The use of environmental interventions to improve outcomes in asthmatics has long been an elusive goal. While numerous interventions have been studied, the results of clinical trials have been mixed. This review aims to identify combinations of interventions that have been proven to be effective and to propose a model for using them in a clinical setting. RECENT FINDINGS: An NIH workshop emphasized a need for research to identify effective interventions for reducing indoor exposures and improving asthma outcomes. A number of innovative measures were described, though evidence supporting their use was lacking. A recent systematic review described various interventions for which evidence is available. The greatest challenge for this approach is the same as that for the medical approach to treatment: nonadherence. Given evidence for effective interventions, control of environmental exposures should lead to improved asthma outcomes. Methods to improve adherence need to be identified. PMID- 29470669 TI - Electrospun poly(caprolactone)-elastin scaffolds for peripheral nerve regeneration. AB - Peripheral nerve regeneration can be enhanced by chemical and mechanical cues for neurite growth. Aligned and randomly oriented electrospun nanofibers of poly(epsilon-caprolactone) (PCL) or a blend of PCL and elastin were fabricated to test their potential to provide contact guidance to embryonic chick dorsal root ganglia for peripheral nerve regeneration. Scanning electron microscopy was used to analyze the fiber diameter. Fiber diameter was found to be significantly smaller when elastin was incorporated into the scaffold (934 +/- 58 nm for PCL and 519 +/- 36 nm for PCL:elastin). After 24 h in culture, there was preferential cell attachment and neurite extension along the fibers of the elastin-containing scaffolds (average neurite extension 173.4 +/- 20.7 MUm), indicating that the presence of elastin promotes neurite outgrowth on electrospun scaffolds. PMID- 29470671 TI - Predicting soil water content at - 33 kPa by pedotransfer functions in stoniness 1 soils in northeast Venezuela. AB - Soil water content is a key property in the study of water available for plants, infiltration, drainage, hydraulic conductivity, irrigation, plant water stress and solute movement. However, its measurement consumes time and, in the case of stony soils, the presence of stones difficult to determinate the water content. An alternative is the use of pedotransfer functions (PTFs), as models to predict these properties from readily available data. The present work shows a comparison of different widely used PTFs to estimate water content at-33 kPa (WR-33kPa) in high stoniness soils. The work was carried out in the Caramacate River, an area of high interest because the frequent landslides worsen the quality of drinking water. The performance of all evaluated PTFs was compared with a PTF generated for the study area. Results showed that the Urach's PTF presented the best performance in relation to the others and could be used to estimate WR-33kPa in soils of Caramacate River basin. The calculated PTFs had a R2 of 0.65. This was slightly higher than the R2 of the Urach's PTF. The inclusion of the rock fragment volume could have the better results. The weak performance of the other PTFs could be related to the fact that the mountain soils of the basin are rich in 2:1 clay and high stoniness, which were not used as independent variables for PTFs to estimate the WR-33kPa.

AB - This study aims at finding out if multiple attenuated internal reflection infrared (MAIR-IR) spectroscopic analysis can be used as a tool to differentiate commercial resin composite brands and to find out if different resin composites will have different abilities of leaching materials that are cytotoxic to human gingival fibroblasts (HGFs) Tooth-colored resin fillings have become increasingly popular as restorative materials, which make it important to differentiate the commercial brands for forensic and biological purposes. Fourteen resin composite brands were used in the study. MAIR-IR spectroscopic analysis was used for surface characterization of the organic and inorganic parts of the resin composite samples which were studied as is and after 2 weeks of saline incubation. IR spectroscopy was also done on the saline extracts to find out if different resin composite materials would have different leaching abilities. The saline extracts were also used for the viability testing of HGF cell cultures. One-way analysis of variance test statistics was used to analyze the results. It was found that the resin composite brands have different spectra after saline soaking. It was also found that these resin composite brands possess different leaching abilities with regard to the amount and type of materials and different cytotoxic effects, which were found to be threshold dependent, meaning there is a critical or threshold value of leaching material at or above which the toxic effect will be significant and below which there is no toxic effect. Therefore, IR spectroscopy might be considered as a useful tool for dental resin composite characterization. However, more oral simulating environmental testing methods, different surface characterization methods, and more cell viability testing methods and assays must be considered for more specific results which relate more to the behavior of these dental resin composites in the oral environment.

AB - In most countries, surprisingly little is known on how national healthcare spending is distributed across diseases. Single-disease cost-of-illness studies cover only a few of the diseases affecting a population and in some cases lead to untenably large estimates. The objective of this study was to decompose healthcare spending in 2011, according to Swiss National Health Accounts, into 21 collectively exhaustive and mutually exclusive major disease categories. Diseases were classified following the Global Burden of Disease Study. We first assigned the expenditures directly mapping from National Health Accounts to the 21 diseases. The remaining expenditures were assigned based on diagnostic codes and clues contained in a variety of microdata sources. Expenditures were dominated by non-communicable diseases with a share of 79.4%. Cardiovascular diseases stood out with 15.6% of total spending, followed by musculoskeletal disorders (13.4%), and mental and substance use disorders (10.6%). Neoplasms (6.0% of the total) ranked only sixth, although they are the leading cause of premature death in Switzerland. These results may be useful for the design of health policies, as they illustrate how healthcare spending is influenced by the epidemiological transition and increasing life expectancy. They also provide a plausibility check for single cost-of-illness studies. Our study may serve as a starting point for further research on the drivers of the constant growth of healthcare spending.

AB - Sericin and fibroin are the two major proteins in the silk fibre produced by the domesticated silkworm, Bombyx mori. Fibroin has been extensively investigated as a biomaterial. We have previously shown that fibroin can function successfully as a substratum for growing cells of the eye. Sericin has been so far neglected as a biomaterial because of suspected allergenic activity. However, this misconception has now been dispelled, and sericin's biocompatibility is currently indisputable. Aiming at promoting sericin as a possible substratum for the growth of corneal cells in order to make tissue-engineered constructs for the restoration of the ocular surface, in this study we investigated the attachment and growth in vitro of human corneal limbal epithelial cells (HLECs) on sericin-based membranes. Sericin was isolated and regenerated from the silkworm cocoons by an aqueous procedure, manufactured into membranes, and characterized (mechanical properties, structural analysis, contact angles). Primary cell cultures from two donors were established in serum-supplemented media in the presence of murine feeder cells. Membranes made of sericin and fibroin-sericin blends were assessed in vitro as substrata for HLECs in a serum-free medium, in a cell attachment assay and in a 3 day cell growth experiment. While the mechanical characteristics of sericin were found to be inferior to those of fibroin, its ability to enhance the attachment of HLECs was significantly superior to fibroin, as revealed by the PicoGreen(r) assay. Evidence was also obtained that cells can grow and differentiate on these substrata.

AB - St. Catherine of Siena suffered from an extreme form of holy fasting, a condition classified as anorexia mirabilis (also known as inedia prodigiosa). Historical and medical scholarships alike have drawn a comparison between this primaeval type of anorexia with a relatively common form of eating disorder among young women in the modern world, anorexia nervosa. St. Catherine's condition was characterised by a disgust for sweet taste, a condition also described in anorexia nervosa, and characterised by specific neurophysiological changes in the brain. St. Catherine's case may be considered one of the oldest veritable descriptions of altered gustation (dysgeusia). Moreover, a more compelling neurophysiological similarity between anorexia mirabilis and anorexia nervosa may be proposed. PMID- 29470670 TI - Calcium orthophosphate coatings, films and layers. AB - In surgical disciplines, where bones have to be repaired, augmented or improved, bone substitutes are essential. Therefore, an interest has dramatically increased in application of synthetic bone grafts. As various interactions among cells, surrounding tissues and implanted biomaterials always occur at the interfaces, the surface properties of the implants are of the paramount importance in determining both the biological response to implants and the material response to the physiological conditions. Hence, a surface engineering is aimed to modify both the biomaterials, themselves, and biological responses through introducing desirable changes to the surface properties of the implants but still maintaining their bulk mechanical properties. To fulfill these requirements, a special class of artificial bone grafts has been introduced in 1976. It is composed of various mechanically stable (therefore, suitable for load bearing applications) biomaterials and/or bio-devices with calcium orthophosphate coatings, films and layers on their surfaces to both improve interactions with the surrounding tissues and provide an adequate bonding to bones. Many production techniques of calcium orthophosphate coatings, films and layers have been already invented and new promising techniques are continuously investigated. These specialized coatings, films and layers used to improve the surface properties of various types of artificial implants are the topic of this review.

AB - The present work is aimed at investigating the mechanical and in vitro biological properties of polyphenylene ether ether sulfone (PPEES)/nanohydroxyapatite (nHA) composite fibers. Electrospinning was used to prepare nanofiber composite mats of PPEES/nHA with different weight percentages of the inorganic filler, nHA. The fabricated composites were characterized using Fourier transform infrared spectroscopy (FTIR)-attenuated total reflectance spectroscopy (ATR) and scanning electron microscopy (SEM)-energy dispersive X-ray spectroscopy (EDX) techniques. The mechanical properties of the composite were studied with a tensile tester. The FTIR-ATR spectrum depicted the functional group as well as the interaction between the PPEES and nHA composite materials; in addition, the elemental groups were identified with EDX analysis. The morphology of the nanofiber composite was studied by SEM. Tensile strength analysis of the PPEES/nHA composite revealed the elastic nature of the nanofiber composite reinforced with nHA and suggested significant mechanical strength of the composite. The biomineralization studies performed using simulated body fluid with increased incubation time showed enhanced mineralization, which showed that the composites possessed high bioactivity property. Cell viability of the nanofiber composite, studied with osteoblast (MG-63) cells, was observed to be higher in the composites containing higher concentrations of nHA.

AB - Assertions regarding attempts to link glial and macrostructural brain events with cognitive performance regarding Albert Einstein, are critically reviewed. One basic problem arises from attempting to draw causal relationships regarding complex, delicately interactive functional processes involving finely tuned molecular and connectivity phenomena expressed in cognitive performance, based on highly variable brain structural events of a single, aged, formalin fixed brain. Data weaknesses and logical flaws are considered. In other instances, similar neuroanatomical observations received different interpretations and conclusions, as those drawn, e.g., from schizophrenic brains. Observations on white matter events also raise methodological queries. Additionally, neurocognitive considerations on other intellectual aptitudes of A. Einstein were simply ignored. PMID- 29470678 TI - An integrated experimental and modeling approach to propose biotinylated PLGA microparticles as versatile targeting vehicles for drug delivery. AB - Polymeric microparticles with covalently attached biotin are proposed as versatile targeting vehicles for drug delivery. The proposed microparticles made of 85/15 poly (lactic-co-glycolic acid) (PLGA) will have biotin available on the outside of the particle for the further attachment with an avidin group. Taking advantage of biotin's high affinity for avidin, and avidin's well-known chemistry, the particle has the potential to be easily coated with a variety of targeting moieties. This paper focuses on the design and resulting effect of adding biotin to PLGA microparticles using an integrated experimental and modeling approach. A fluorescent-tagged avidin (488-streptavidin) was used to confirm the presence and bioavailability of biotin on the outside of the particles. For the purpose of this study, bovine serum albumin (BSA) was used as a model therapeutic drug. Microparticles were created using two different types of polyvinyl alcohol 88 and 98 mol% hydrolyzed, which were then analyzed for their size, morphology, and encapsulation capacity of BSA. Release studies performed in vitro confirmed the slow release of the BSA over a 28-day period. Based on these release profiles, a release kinetics model was used to further quantify the effect of biotinylation of PLGA microparticles on their release characteristics by quantitatively extracting the effective drug diffusivity and drug desorption rate from the release profiles. It was found that the biotinylation of the PLGA microparticles slowed down both the drug desorption and drug diffusion process, which confirmed that biotinylated PLGA microparticles can be used for controlled drug release. The presented technology, as well as the proposed integrated experimental and modeling approach, forms a solid foundation for future studies using a cell-specific ligand that can be attached to avidin and incorporated onto the microparticles for targeted delivery.

PMID- 29470680 TI - Changes in Skeletal Muscle and Body Weight on Sleeping Beauty Transposon-Mediated Transgenic Mice Overexpressing Pig mIGF-1. AB - Insulin-like growth factor (IGF-I) is an important growth factor in mammals, but the functions of the local muscle-specific isoform of insulin-like growth factor 1 (mIGF-1) to skeletal muscle development have rarely been reported. To determine the effect of pig mIGF-1 on body development and muscle deposition in vivo and to investigate the molecular mechanisms, the transgenic mouse model was generated which can also provide experimental data for making transgenic pigs with pig endogenous IGF1 gene. We constructed a skeletal muscle-specific expression vector using 5'- and 3'-regulatory regions of porcine skeletal alpha-actin gene. The expression cassette was flanked with Sleeping Beauty transposon (SB)-inverted terminal repeats. The recombinant vector could strongly drive enhanced green fluorescence protein (EGFP) reporter gene expression specifically in mouse myoblast cells and porcine fetal fibroblast cells, but not in porcine kidney cells. The EGFP level driven by alpha-actin regulators was significantly stronger than that driven by cytomegalovirus promoters. These results indicated that the cloned alpha-actin regulators could effectively drive specific expression of foreign genes in myoblasts, and the skeletal muscle-specific expression vector mediated with SB transposon was successfully constructed. To validate the effect of pig mIGF-1 on skeletal muscle growth, transgenic mice were generated by pronuclear microinjection of SB-mediated mIGF-1 skeletal expression vector and SB transposase-expressing plasmid. The transgene-positive rates of founder mice and the next-generation F1 mice were 30% (54/180) and 90.1% (64/71), respectively. The mIGF-1 gene could be expressed in skeletal muscle specifically. The levels of mRNA and protein in transgenic mice were 15 and 3.5 times higher, respectively, than in wild-type mice. The body weights of F1 transgenic mice were significantly heavier than wild-type mice from the age of 8 weeks onwards. The paraffin embedded sections of gastrocnemius from 16-week-old transgenic male mice showed that the numbers of myofibers per unit were increased in comparison with those in the wild-type mice. mIGF-1 overexpression in mice skeletal muscle may promote myofibers hypertrophy and muscle production, and increased the average body weight of adult mice. Transgenic mice models can be generated by the mediation of SB transposon with high transgene efficiency. PMID- 29470682 TI - Structure and biocompatibility of poly(vinyl alcohol)-based and agarose-based monolithic composites with embedded divinylbenzene-styrene polymeric particles. AB - Macroporous monolithic composites with embedded divinylbenzene-styrene (DVB-ST) polymeric particles were prepared by cryogelation techniques using poly(vinyl alcohol) or agarose solutions. Scanning electron microscopy images showed multiple interconnected pores with an average diameter in the range of 4 to 180 MUm and quite homogeneous distribution of DVB-ST particles in the composites. Biocompatibility of the composites was assessed by estimation of the C5a fragment of complement in the blood serum and concentration of fibrinogen in the blood plasma which contacted the composites. A time-dependent generation of C5a fragment indicated weak activation of the complement system. At the same time, the difference in fibrinogen concentration, one of the most important proteins in the coagulation system of the blood, between the pristine blood plasma and the plasma, circulated through the monolithic columns, was insignificant. PMID- 29470681 TI - A large-scale multiomics analysis of wheat stem solidness and the wheat stem sawfly feeding response, and syntenic associations in barley, Brachypodium, and rice. AB - The wheat stem sawfly (WSS), Cephus cinctus Norton (Hymenoptera: Cephidae), is an important pest of wheat and other cereals, threatening the quality and quantity of grain production. WSS larvae feed and develop inside the stem where they are protected from the external environment; therefore, pest management strategies primarily rely on host plant resistance. A major locus on the long arm of wheat chromosome 3B underlies most of the variation in stem solidness; however, the impact of stem solidness on WSS feeding has not been completely characterized. Here, we used a multiomics approach to examine the response to WSS in both solid- and semi-solid-stemmed wheat varieties. The combined transcriptomic, proteomic, and metabolomic data revealed that two important molecular pathways, phenylpropanoid and phosphate pentose, are involved in plant defense against WSS. We also detected a general downregulation of several key defense transcripts, including those encoding secondary metabolites such as DIMBOA, tricetin, and lignin, which suggested that the WSS larva might interfere with plant defense. We comparatively analyzed the stem solidness genomic region known to be associated with WSS tolerance in wild emmer, durum, and bread wheats, and described syntenic regions in the close relatives barley, Brachypodium, and rice. Additionally, microRNAs identified from the same genomic region revealed potential regulatory pathways associated with the WSS response. We propose a model outlining the molecular responses of the WSS-wheat interactions. These findings provide insight into the link between stem solidness and WSS feeding at the molecular level.

AB - In this study, we retrospectively compared the prognostic value of the 2016 WHO classification with the former classification in 387 patients with glioma treated at our institution. According to the new classification, diagnoses included oligodendroglioma with isocitrate dehydrogenase (IDH) mutation and 1p/19q co deletion (5.4%), anaplastic oligodendroglioma with IDH mutation and 1p/19q co deletion (3.4%), diffuse astrocytoma IDH-mutated (3.9%), anaplastic astrocytoma IDH-mutated (2.8%), glioblastoma IDH-mutated (7.8%), glioblastoma IDH-wildtype (58.4%), diffuse midline glioma H3 K27M mutation (2.6%), oligodendroglioma NOS (1.3%), anaplastic oligodendroglioma NOS (0.8%), diffuse astrocytoma IDH-wildtype (2.8%), and anaplastic astrocytoma IDH-wildtype (10.9%). The prognoses of IDH mutated astrocytomas clearly varied according to tumor grade. However, we identified no survival difference between IDH-wildtype anaplastic astrocytomas and glioblastomas; additionally, these tumors showed similar gene expression profiles. After exclusion of those without 1p/19q co-deletion, patients with oligodendroglial tumors showed excellent survival regardless of tumor grade. Our evaluation of chromosomal aberrations suggests that the MAPK/PI3K pathway plays a role in acquired malignancy of astrocytic tumors, whereas TP53 participates in tumorigenesis. We suspect the RB pathway also plays a role in tumorigenesis of IDH-mutated gliomas. The new WHO classification more clearly reflects the tumorigenesis of gliomas and improves the prognostic power of classification. PMID- 29470684 TI - Comparative studies on osteogenic potential of micro- and nanofibre scaffolds prepared by electrospinning of poly(epsilon-caprolactone). AB - The biocompatibility and osteogenic potential of four fibrous scaffolds prepared by electrospinning of poly(epsilon-caprolactone) (PCL) was studied with MG-63 osteoblast cells. Two different kinds of scaffolds were obtained by adjustment of spinning conditions, which were characterized as nano- or microfibrous. In addition of one nanofibrous, scaffold was made more hydrophilic by blending PCL with Pluronics F 68. Scaffolds were characterized by scanning electron microscopy and water contact angle measurements. Morphology and growth of MG63 cells seeded on the different scaffolds were investigated by confocal laser scanning microscopy after vital staining with fluorescein diacetate and by colorimetric assays. It was found that scaffolds composed of microfibres stipulated better growth conditions for osteoblasts probably by providing a real three-dimensional culture substratum, while nanofibre scaffolds restricted cell growth predominantly to surface regions. Osteogenic activity of cells was determined by alkaline phosphatase (ALP) and o-cresolphthalein complexone assay. It was observed that osteogenic activity of cells cultured in microfibre scaffolds was significantly higher than in nanofibre scaffolds regarding ALP activity. Overall, one can conclude that nanofibre scaffold provides better conditions for initial attachment of cells but does not provide advantages in terms of scaffold colonization and support of osteogenic activity compared to scaffolds prepared from microfibres. PMID- 29470685 TI - The effect of halogen light stimulation on duration of ultrasound parameters of biophysical profile: a randomized clinical trial. AB - INTRODUCTION: The objective is to assess if fetal halogen light stimulation can reduce the time needed to obtain a normal biophysical profile (BPP). METHODS: Patients scheduled for a BPP and who satisfied the inclusion criteria were prospectively randomized to halogen light stimulation and no stimulation groups. The study group was exposed to handheld halogen light for 10 s whenever fetal breathing, movement, or tone was absent through the first 5 min of BPP. The time required to achieve complete BPP score was recorded. In patients with complete BPP score who had delivery within 1 week after the test, perinatal morbidity was examined. RESULTS: A total of 598 patients were randomized (light = 302, no light = 296). There was no difference between the two groups in terms of gestational age, maternal age, body mass index, and indication for BPP except for preterm labor (light: 9%, no light: 4%, p = 0.03). Among the patients who had a normal BPP score (n = 507), the mean (light: 7.1 +/- 6 min, no light: 12.3 +/- 8 min, p < 0.0001) and median (light: 4.3, no light: 8, p = 0.004) time needed to complete the BPP score was significantly less in the light stimulation group than the no stimulation group. Perinatal outcomes were not different between groups who had delivery during the first week after BPP. CONCLUSION: Fetal halogen light stimulation can be utilized to reduce the time needed to complete a BPP. However, further studies should be conducted in order to determine the effect of this method on decreasing non-reassuring test results. CLINICAL TRIAL REGISTRATION: The study was submitted to the Registry of Clinical Trials on 04/20/2017 (IRCT2017041633470N1). After IRCT registration on 06/07/2017, we recruited patients from 06/08/2017 till 10/15/2017. PMID- 29470686 TI - A case of stage IA pancreatic ductal adenocarcinoma accompanied with focal pancreatitis demonstrated by contrast-enhanced ultrasonography. AB - A patient with slight dilatation of the main pancreatic duct was followed-up with ultrasonography every 6 months as a high-risk case of pancreatic cancer. Twelve years later, a faint hypoechoic area 13 mm in diameter was first detected on the body of the pancreas. Contrast-enhanced ultrasonography revealed a well demarcated hypoenhanced area 8 mm in diameter and a hyperenhanced area with an unclear margin. The former was suspected to be a small pancreatic cancer lesion, and the latter to be focal pancreatitis accompanying cancer. However, contrast enhanced dynamic CT did not suggest any tumor, diagnosis of adenocarcinoma was confirmed with pancreatic juice cytology through endoscopic retrograde pancreatography. Surgical resection was performed, and the lesion was pathologically diagnosed as invasive ductal carcinoma as follows: pTS1 (1.0 cm), infiltrative type (pT1), stage IA. When comparing the images from contrast enhanced ultrasonography with the pathological findings, the hypoenhanced area corresponded to ductal adenocarcinoma, and the hyperenhanced area to focal pancreatitis. Contrast-enhanced ultrasonography was able to reveal detailed information on the focal lesion in the pancreas, and it was effective for the early diagnosis of pancreatic cancer.

AB - BACKGROUND: We retrospectively evaluated the initial clinical experience of the surgical management of extensive dissecting thoracic aortic aneurysm (TAA) via the semi-clamshell approach. METHODS: Thirteen patients (3 women and 10 men, mean age 67 +/- 15 years) who underwent elective surgical intervention for extensive dissecting TAA via semi-clamshell approach in our institute between May 2007 and April 2017 participated in this study. Regarding surgical techniques, left thoracotomy with transverse sternotomy was initially performed via the third or fourth intercostal space following an incision from the right sternal borderline to the anterior axillary line on the left sternal borderline. Cardiopulmonary bypass was then established and extensive graft replacement was conducted with hypothermia. RESULTS: Extensive total arch replacement (TAR) was performed on 4 patients, TAR with descending thoracic aortic replacement (DTAR) on 4, distal hemiarch replacement with DTAR on 3, and extensive graft replacement from the ascending to descending thoracic aorta on 2. There was one (7.7%) case of surgical and hospital mortality due to low-output syndrome. None of our patients developed respiratory failure requiring secondary tracheotomy; however, new-onset cerebrovascular infarction was noted in 2 (15.4%). No mediastinitis or serious infectious complications were observed after surgery. With a mean follow-up period of 45.1 +/- 44.1 months, a Kaplan-Meier analysis revealed that 1- and 5 year survival rates were both 92.3%, respectively. CONCLUSIONS: The surgical management of extensive dissecting TAA by semi-clamshell approach may contribute to acceptable early clinical outcomes in high-risk patients, and represents an alternative surgical option in the current endovascular era. PMID- 29470688 TI - Spatial variability and geochemistry of rare earth elements in soils from the largest uranium-phosphate deposit of Brazil. AB - The Itataia uranium-phosphate deposit is the largest uranium reserve in Brazil. Rare earth elements (REEs) are commonly associated with phosphate deposits; however, there are no studies on the concentrations of REEs in soils of the Itataia deposit region. Thus, the objective of the research was to evaluate the concentration and spatial variability of REEs in topsoils of Itataia phosphate deposit region. In addition, the influence of soil properties on the geochemistry of REEs was investigated. Results showed that relatively high mean concentrations (mg kg-1) of heavy REEs (Gd 6.01; Tb 1.25; Ho 1.15; Er 4.05; Tm 0.64; Yb 4.61; Lu 0.65) were found in surface soils samples. Soil properties showed weak influence on the geochemical behavior of REEs in soils, except for the clay content. On the other hand, parent material characteristics, such as P and U, had strong influence on REEs concentrations. Spatial distribution patterns of REEs in soils are clearly associated with P and U contents. Therefore, geochemical surveys aiming at the delineation of ore-bearing zones in the region can benefit from our data. The results of this work reinforce the perspective for co-mining of P, U and REEs in this important P-U reserve. PMID- 29470690 TI - Early introduction of complementary foods and childhood overweight in breastfed and formula-fed infants in the Netherlands: the PIAMA birth cohort study. AB - PURPOSE: To investigate whether early introduction of complementary foods (CF) is associated with an increased risk of overweight during childhood, and whether this association differs between formula-fed and breastfed infants. METHODS: We included 2611 participants that were born at term from a Dutch population-based birth cohort (n = 3963) designed to investigate the development of asthma and allergies. Parents kept records of their infant's age when CF were first introduced. Weight and height were parent reported yearly from age 1 to 8 years, and at ages 11, 14 and 17 years. We used multivariate generalized estimating equations analysis to investigate the association between timing of CF introduction (before 4 months vs at or after 4 months of age) and overweight at ages 1-17 years. RESULTS: Children with CF introduction before 4 months had higher odds of being overweight during childhood than children with CF introduction at or after 4 months (OR 1.32, 95% CI 1.19, 1.47). This association was observed in formula-fed infants (OR 1.51, 95% CI 1.17, 1.94) and breastfed infants (OR 1.32, 95% CI 1.19, 1.47). The duration of breastfeeding modified the association between CF introduction and overweight: children breastfed for shorter than 4 months, but not children breastfed for 4 months or longer with CF introduction before 4 months had higher odds of being overweight (OR 1.37, 95% CI 1.19, 1.57 and 1.07, 95% CI 0.87, 1.32, respectively), compared to those with CF introduction at or after 4 months. CONCLUSIONS: In children born at term, formula fed infants and infants who were breastfed for shorter than 4 months, but not infants who were breastfed for 4 months or longer, had a higher risk of being overweight during childhood when being introduced to CF before 4 months of age. PMID- 29470689 TI - The nutritional and health attributes of kiwifruit: a review. AB - PURPOSE: To describe the nutritional and health attributes of kiwifruit and the benefits relating to improved nutritional status, digestive, immune and metabolic health. The review includes a brief history of green and gold varieties of kiwifruit from an ornamental curiosity from China in the 19th century to a crop of international economic importance in the 21st century; comparative data on their nutritional composition, particularly the high and distinctive amount of vitamin C; and an update on the latest available scientific evidence from well designed and executed human studies on the multiple beneficial physiological effects. Of particular interest are the digestive benefits for healthy individuals as well as for those with constipation and other gastrointestinal disorders, including symptoms of irritable bowel syndrome. The mechanisms of action behind the gastrointestinal effects, such as changes in faecal (stool) consistency, decrease in transit time and reduction of abdominal discomfort, relate to the water retention capacity of kiwifruit fibre, favourable changes in the human colonic microbial community and primary metabolites, as well as the naturally present proteolytic enzyme actinidin, which aids protein digestion both in the stomach and the small intestine. The effects of kiwifruit on metabolic markers of cardiovascular disease and diabetes are also investigated, including studies on glucose and insulin balance, bodyweight maintenance and energy homeostasis. CONCLUSIONS: The increased research data and growing consumer awareness of the health benefits of kiwifruit provide logical motivation for their regular consumption as part of a balanced diet. Kiwifruit should be considered as part of a natural and effective dietary strategy to tackle some of the major health and wellness concerns around the world. PMID- 29470691 TI - Even effect of milk protein and carbohydrate intake but no further effect of heavy resistance exercise on myofibrillar protein synthesis in older men. AB - PURPOSE: The responsiveness of older individuals' skeletal muscle to anabolic strategies may be impaired. However, direct comparisons within the same experimental setting are sparse. The aim of this study was to assess the resting and post-resistance exercise muscle protein synthesis rates in response to two types of milk protein and carbohydrate using a unilateral exercise leg model. METHODS: Twenty-seven older (69 +/- 1 year, mean +/- SE) men were randomly assigned one of three groups: Whey hydrolysate (WH), caseinate (CAS), or carbohydrate (CHO). By applying stable isotope tracer techniques (L [15N]phenylalanine), the fasted-rested (basal) myofibrillar fractional synthesis rate (FSR) was measured. Hereafter, FSR was measured in the postprandial phase (0.45 g nutrient/kg LBM) in both legs, one rested (fed-rest) and one exercised (10 * 8 reps at 70% 1RM; fed-exercise). In addition, the activity of p70S6K and venous plasma insulin, phenylalanine, and leucine concentrations were measured. RESULTS: Insulin, phenylalanine, and leucine concentrations differed markedly after intake of the different study drinks. The basal FSR in WH, CAS, and CHO were 0.027 +/- 0.003, 0.030 +/- 0.003, and 0.030 +/- 0.004%/h, the fed-rested FSR were 0.043 +/- 0.004, 0.045 +/- 0.003, and 0.035 +/- 0.004%/h, and the fed exercised FSR were 0.041 +/- 0.004, 0.043 +/- 0.004, and 0.034 +/- 0.004%/h, respectively. No significant differences were observed at any state between the groups. Fed-rested- and fed-exercised FSR were higher than basal (P < 0.001). 3 h after exercise and feeding, no significant group differences were detected in the activity of p70S6K. CONCLUSIONS: Milk protein and carbohydrate supplementation stimulate myofibrillar protein synthesis in older men, with no further effect of heavy resistance exercise within 0-3 h post exercise. PMID- 29470692 TI - Validation of the Chowdhury overall survival score in patients with melanoma brain metastasis treated with Gamma Knife Radiosurgery. AB - Melanoma brain metastases (MBM) are common in patients with stage IV disease. For Gamma Knife radiosurgery (GKRS) on MBM, risk scores such as RPA and melanoma-GPA aid to identify prognostic subgroups. This study aimed to validate the overall survival (OS) risk score developed by Chowdhury et al. in our center's patient cohort. A total of 104 MBM patients were treated with GKRS between 1/1/2002 and 31/12/2014 in our institution. Patients were categorized according to RPA, melanoma-GPA and Chowdhury OS score. The Kaplan-Meier method was used to estimate overall survival, and predicted survival probabilities were calculated for calibration. Cox proportional hazards regressions were performed to identify additional risk factors. Overall, median follow-up time was 80 months, while median OS (mOS) after GKRS was 6 months. Stratified according to the Chowdhury OS score, mOS in the high, medium and low risk group was 3.4, 7.1, and 10.0 months, respectively. The addition of other patient or disease characteristics to the Chowdhury OS model did not improve its performance. The C-index of the melanoma GPA was 0.46 while the Chowdhury OS had an index of 0.67. In comparison with the RPA and melanoma-GPA, the Chowdhury OS score more accurately distinguished between separate risk groups among patients with MBM treated with GKRS. Contrary to the original study by Chowdhury, follow-up time was sufficient here for the low-risk group to reach the mOS time of 10 months. PMID- 29470693 TI - Anti-inflammatory, anti-rheumatic and analgesic activities of 2-(5-mercapto-1,3,4 oxadiazol-2-yl)-N-propylbenzenesulphonamide (MOPBS) in rodents. AB - Chronic inflammation is pathologically associated with various clinical conditions such as rheumatoid arthritis. Several anti-inflammatory and analgesic drugs currently available in market presents a wide range of problems. Therefore, the current study was aimed to evaluate anti-inflammatory and analgesic activities of newly synthesized compound 2-(5-mercapto-1,3,4-oxadiazol-2-yl)-N propylbenzenesulphonamide (MOPBS). Carrageenan and CFA-induced models were developed for evaluation of anti-inflammatory and analgesic activity. Quantitative real-time PCR (qRT-PCR) was performed to determine the mRNA expression levels of inflammatory mediators. Pain behaviours were evaluated by performing Von Frey, Randall Selitto, cold acetone and hot plate test respectively. X-ray imaging and haematoxylin and eosin (H&E) staining were performed for examination of soft tissues of treated mice paw. Additionally, Kodzeila's screen test and weight test were performed for determination of any side effects on motor function and muscle strength. Acute pretreatment of animals with MOPBS (1, 10, 50 and 100 mg/kg, i.p.) produced a significant reduction of paw oedema against carrageenan-induced acute inflammation as well as notable inhibition of mechanical hyperalgesia, allodynia and thermal hyperalgesia. Similarly, in chronic inflammation model, administration of MOPBS (50 mg/kg, i.p.) produced a remarkable reduction of paw oedema. Additionally, MOPBS pretreatment showed a significant inhibition of thermal hyperalgesia, mechanical allodynia, and mechanical hyperalgesia in chronic arthritis model. Several pro inflammatory mediators such as nitric oxide (NO), vascular endothelial growth factor (VEGF), interleukins (IL-1beta, IL-6) and tumor necrosis factor-alpha (TNF alpha) were inhibited by MOPBS treatment in blood plasma and paw tissues, respectively. MOPBS also enhanced the mRNA expression levels of nuclear factor (erythroid-derived 2)-like 2 (Nrf2), superoxide dismutase (SOD2) and heme oxygenase (HO-1) and in turn reduced arthritis severity and inflammation. Furthermore, anti-inflammatory data were confirmed by X-rays and histological analysis. MOPBS pretreatment did not produce any apparent toxic effect on gastric, kidney and liver function and on muscle strength and motor function. Hence, the present data suggest that MOPBS might be a candidate for several chronic inflammatory diseases such RA and other auto-immune diseases.

AB - Temporal lobe epilepsy (TLE) is present in 30% of epileptic patients and does not respond to conventional treatments. Bone marrow derived mesenchymal stem cells (BMSCs) induce endogenous neural stem cells, inhibit neurodegeneration, and promote brain self-repair mechanisms. The present study addresses the feasibility of BMSCs transplantation against pilocarpine-induced TLE experimentally. BMSCs were injected either intravenously (IV) or in hippocampus bilaterally (IC). Increased cell count of BMSCs was achieved via IC route. BMSCs treatment ameliorated the pilocarpine-induced neurochemical and histological changes, retained amino acid neurotransmitters to the normal level, downregulated the immunoreactivity to insulin growth factor-1 receptor, synaptophysin, and caspase 3 and reduced oxidative insult and inflammatory markers detected in epileptic model. It is worth noting that BMSCs IC-administered showed more pronounced effects than those administered via IV route. BMSCs transplantation presents a promise for TLE treatment that has to be elucidated clinically. PMID- 29470696 TI - Additive hazards model with auxiliary subgroup survival information. AB - The semiparametric additive hazards model is an important way for studying the effect of potential risk factors for right-censored time-to-event data. In this paper, we study the additive hazards model in the presence of auxiliary subgroup [Formula: see text]-year survival information. We formulate the known auxiliary information in the form of estimating equations, and combine them with the conventional score-type estimating equations for the estimation of the regression parameters based on the maximum empirical likelihood method. We prove that the new estimator of the regression coefficients follows asymptotically a multivariate normal distribution with a sandwich-type covariance matrix that can be consistently estimated, and is strictly more efficient, in an asymptotic sense, than the conventional one without incorporation of the available auxiliary information. Simulation studies show that the new proposal has substantial advantages over the conventional one in terms of standard errors, and with the accommodation of more informative information, the proposed estimator becomes more competing. An AIDS data example is used for illustration. PMID- 29470695 TI - A banana NAC transcription factor (MusaSNAC1) impart drought tolerance by modulating stomatal closure and H2O2 content. AB - KEY MESSAGE: MusaSNAC1 function in H2O2 mediated stomatal closure and promote drought tolerance by directly binding to CGT[A/G] motif in regulatory region of multiple stress-related genes. Drought is a abiotic stress-condition, causing reduced plant growth and diminished crop yield. Guard cells of the stomata control photosynthesis and transpiration by regulating CO2 exchange and water loss, thus affecting growth and crop yield. Roles of NAC (NAM, ATAF1/2 and CUC2) protein in regulation of stress-conditions has been well documented however, their control over stomatal aperture is largely unknown. In this study we report a banana NAC protein, MusaSNAC1 which induced stomatal closure by elevating H2O2 content in guard cells during drought stress. Overexpression of MusaSNAC1 in banana resulted in higher number of stomata closure causing reduced water loss and thus elevated drought-tolerance. During drought, expression of GUS (beta glucuronidase) under P MusaSNAC1 was remarkably elevated in guard cells of stomata which correlated with its function as a transcription factor regulating stomatal aperture closing. MusaSNAC1 is a transcriptional activator belonging to SNAC subgroup and its 5'-upstream region contain multiple Dof1 elements as well as stress-associated cis-elements. Moreover, MusaSNAC1 also regulate multiple stress-related genes by binding to core site of NAC-proteins CGT[A/G] in their 5' upstream region. Results indicated an interesting mechanism of drought tolerance through stomatal closure by H2O2 generation in guard cells, regulated by a NAC protein in banana. PMID- 29470697 TI - Reliability analysis of load-sharing systems with memory. AB - The load-sharing model has been studied since the early 1940s to account for the stochastic dependence of components in a parallel system. It assumes that, as components fail one by one, the total workload applied to the system is shared by the remaining components and thus affects their performance. Such dependent systems have been studied in many engineering applications which include but are not limited to fiber composites, manufacturing, power plants, workload analysis of computing, software and hardware reliability, etc. Many statistical models have been proposed to analyze the impact of each redistribution of the workload; i.e., the changes on the hazard rate of each remaining component. However, they do not consider how long a surviving component has worked for prior to the redistribution. We name such load-sharing models as memoryless. To remedy this potential limitation, we propose a general framework for load-sharing models that account for the work history. Through simulation studies, we show that an inappropriate use of the memoryless assumption could lead to inaccurate inference on the impact of redistribution. Further, a real-data example of plasma display devices is analyzed to illustrate our methods. PMID- 29470698 TI - Permanent Hypoparathyroidism After Total Thyroidectomy in Children: Results from a National Registry. AB - INTRODUCTION: Hypoparathyroidism is the most common complication following thyroidectomy. There are few population-based reports on the rate of hypoparathyroidism in children. The incidence of medical treatment of permanent hypoparathyroidism in children is reported using a national registry. METHODS: The study population included patients below 18 years of age undergoing total thyroidectomy reported to the Scandinavian Quality Registry for Thyroid, Parathyroid and Adrenal Surgery 2004-2014. Patients with previous thyroid or parathyroid surgery or treatment with vitamin D before surgery were excluded from analysis. Permanent postoperative hypoparathyroidism was defined as treatment with vitamin D for more than 6 months after thyroidectomy. Risk factors for permanent hypoparathyroidism were calculated with uni- and multivariable logistic regression. Using data from the Swedish Inpatient Registry, rates of readmissions and annual number of days in hospital after total thyroidectomy were compared between patients with and without permanent hypoparathyroidism. RESULTS: Some 274 children (215 girls and 59 boys) underwent total thyroidectomy. The median age was 14 (range 0-17) years. Indications for surgery were Graves' disease (214, 78.1%), other benign disease (27, 9.9%) and thyroid cancer (33, 12%). Median follow-up was 4.8 years. Twenty (7.3%) children developed permanent hypoparathyroidism. No statistically significant risk factors for permanent hypoparathyroidism were identified. Rates of readmission and annual number of days in hospital after discharge were similar in patients with and without permanent hypoparathyroidism. CONCLUSIONS: The rate of permanent hypoparathyroidism following total thyroidectomy in children was high and is a cause of concern. PMID- 29470699 TI - A Nested Case-Control Study on the Risk of Surgical Site Infection After Thyroid Surgery. AB - INTRODUCTION: It is unclear if antibiotic prophylaxis reduces the risk of surgical site infection (SSI) in thyroid surgery. This study assessed risk factors for SSI and antibiotic prophylaxis in subgroups of patients. METHOD AND DESIGN: A nested case-control study on patients registered in the Swedish National Register for Endocrine Surgery was performed. Patients with SSI were matched 1:1 by age and gender to controls. Additional information on patients with SSI and controls was queried from attending surgeons using a questionnaire. Risk factors for SSI were evaluated by logistic regression analysis and presented as odds ratio (OR) with 95% confidence interval (CI). RESULTS: There were 9494 operations; 109 (1.2%) patients had SSI. Patients with SSI were older (median 53 vs. 49 years) than patients without SSI p = 0.01 and more often had a cancer diagnosis 23 (21.1%) versus 1137 (12.1%) p = 0.01. In the analysis of patients with SSI versus controls, patients with SSI more often had post-operative drainage 68 (62.4%) versus 46 (42.2%) p = 0.01 and lymph node surgery 40 (36.7%) versus 14 (13.0%) p < 0.01, and both were independent risk factors for SSI, drain OR 1.82 (CI 1.04-3.18) and lymph node dissection, OR 3.22 (95% CI 1.32-7.82). A higher number of 26(62%) patients with independent risk factors for SSI and diagnosed with SSI did not receive antibiotic prophylaxis. Data were missing for 8 (31%) patients. CONCLUSION: Lymph node dissection and drain are independent risk factors for SSI after thyroidectomy. Antibiotic prophylaxis might be considered in patients with these risk factors. PMID- 29470700 TI - Incidental Diagnosis of Parathyroid Lesions by Preoperative Use of Next Generation Molecular Testing. AB - BACKGROUND: Parathyroid glands can mimic thyroid follicular lesions on fine needle aspiration (FNA) cytology and can lead to unnecessary or incorrect surgery. Newer molecular panel tests using next-generation sequencing (NGS) include analysis of cell type-specific gene expression profiles such as parathyroid. The study aim is to determine the frequency and clinical implications of parathyroid tissue identification by molecular testing in cytologically indeterminate "thyroid" lesions. METHODS: Molecular analysis of indeterminate thyroid FNA specimens is obtained routinely and relies on amplification-based NGS inclusive of PTH-specific expression profiles. For this study, we retrospectively examined the clinical data and management of patients with molecular results positive for PTH expression from May 2014 until May 2016. RESULTS: Among 4765 consecutive patients with indeterminate cytology for a presumed thyroid nodule, NGS instead indicated a parathyroid lesion in 20 patients (0.42%). The clinical data of 15 patients were available, and the subsequent clinical management was altered in 93% (14/15 patients), including five (33%) eucalcemic patients who could avoid unnecessary surgery. Primary hyperparathyroidism was not suspected in seven patients until the molecular analysis results, and primary hyperparathyroidism was diagnosed in one (14%). During parathyroid exploration, most patients (6/8, 75%) required concurrent thyroidectomy or lobectomy, but thyroid preservation was still possible in two patients. A parathyroid gland was histologically confirmed in 89%. CONCLUSIONS: In 0.42% of patients with indeterminate cytology results, next-generation molecular results will indicate the presence of a parathyroid lesion. When this occurs, it is accurate and can robustly impact clinical management (93%). PMID- 29470701 TI - Preservation of gonadal function in women undergoing chemotherapy: a systematic review and meta-analysis of the potential role for gonadotropin-releasing hormone agonists. AB - PURPOSE: To evaluate the available randomized controlled trials (RCTs) in the literature investigating the use of gonadotropin-releasing hormone agonist (GnRHa) co-treatment for ovarian preservation in women receiving chemotherapy. METHODS: A systematic review of the literature was performed from 1960 through 2017 to identify relevant RCTs. Included patients had lymphoma, ovarian cancer, or breast cancer. The primary outcome was the proportion of women who retained ovarian function after chemotherapy. Extracted data points included study design, patient characteristics, and proportion of women who developed premature ovarian failure (POF). A risk of bias assessment was performed according to the criteria outlined in the Cochrane Handbook for Systematic Reviews of Interventions. The pooled odds ratio was calculated, and outcomes of individual studies were compared using the random-effects model with the inverse-variance method and the DerSimonian-Laird estimator. RESULTS: Twenty-nine RCTs were identified, and 10 met criteria for inclusion in the meta-analysis. An analysis of patients who did not develop POF after chemotherapy revealed eight studies supporting the use of GnRHa (OR 1.83; 95% CI 1.34-2.49). The duration of benefit of GnRHa is unclear. An analysis of three studies with outcome data at 2 years revealed a non significant OR of 0.53 (95% CI 0.22-1.30) for the preservation of ovarian function with GnRHa treatment. CONCLUSION: GnRHa may have a protective effect against the development of POF after gonadotoxic chemotherapy; however, the duration of benefit is unclear and requires further study. PMID- 29470702 TI - The mutual benefits of research in wild animal species and human-assisted reproduction. AB - Studying the reproductive biology of wild animal species produces knowledge beneficial to their management and conservation. However, wild species also share intriguing similarities in reproductive biology with humans, thereby offering alternative models for better understanding the etiology of infertility and developing innovative treatments. The purpose of this review is to raise awareness in different scientific communities about intriguing connections between wild animals and humans regarding infertility syndromes or improvement of fertility preservation. The objectives are to (1) highlight commonalities between wild species and human fertility, (2) demonstrate that research in wild species assisted reproductive technologies can greatly enhance success in human reproductive medicine, and (3) recognize that human fertility preservation is highly inspiring and relevant to wild species conservation. In addition to having similar biological traits in some wild species and humans, the fact of sharing the same natural environment and the common needs for more options in fertility preservation are strong incentives to build more bridges that will eventually benefit both animal conservation and human reproductive medicine. PMID- 29470703 TI - Guide for health professionals addressing oral care for individuals in oncological treatment based on scientific evidence. AB - OBJECTIVE: Oncological treatment can cause changes in the oral cavity compromising oral functions. The aim of the study was, based on a systematic review, to draft a guide directed at the team of health professionals involved in the oral care of oncological patients. METHODS: A systematic search of the literature was performed for articles published between 2000 and April 2017. Searches were made of electronic databases and hand search. The inclusion criteria were systematic reviews of randomized clinical trials (RCTs) and RCTs published in English, involving pediatric and adult oncological patients and focused on the prevention and treatment of oral complications as well as studies addressing the maintenance of oral health. Among the 1237 studies identified, 129 were pre-selected and 54 were selected to form the basis for the clinical guide. RESULTS: The studies analyzed stress the need for oral assessments as well as preventive and curative actions prior to oncological treatment. To minimize the severity of oral problems, the studies emphasize daily oral care, the treatment of xerostomia with saliva substitute and hydration, and low-level laser therapy, nystatin, acyclovir, respectively, for the prevention and treatment of oral mucositis, oral candidiasis, and infection by herpes simplex virus. Thus, the guide produced addresses oral assessments and professional and home care before, during, and after oncological treatment. CONCLUSION: The guide drafted has the function of assisting health professionals involved in the oral care of patients with cancer, enabling the prevention or treatment of oral complications stemming from oncological treatment. PMID- 29470704 TI - Relationship between sleep and exercise as colorectal cancer survivors transition off treatment. AB - PURPOSE: The primary objective of this study was to evaluate the relationship between exercise and sleep disturbance in a sample of individuals diagnosed with stage I, II, and III colorectal cancer (CRC) as patients transitioned off first line treatment. We also sought to identify heterogeneity in the relationship between sleep disturbance and exercise. METHODS: Data were obtained from the MY Health study, a community-based observational study of adults diagnosed with cancer. Patient-Reported Outcomes Measurement Information System(r) (PROMIS) measures (e.g., PROMIS Sleep) were administered, and participants self-reported demographics, comorbidities, cancer treatment, and exercise. Regression mixture and multiple regression models were used to evaluate the relationship between sleep disturbance and exercise cross-sectionally at an average of 10 months after diagnosis, and the change in sleep disturbance over a 7-month period, from approximately 10 to 17 months post-diagnosis. RESULTS: Patients whose exercise was categorized as likely at or above American College of Sports Medicine's guidelines did not report statistically better sleep quality compared to patients who were classified as not active. However, retirement (B = - 2.4), anxiety (B = 0.21), and fatigue (B = 0.24) had statistically significant relationships with sleep disturbance (p < 0.05). Increase in exercise was not significantly associated with a decrease in sleep disturbance. No statistical heterogeneity was revealed in the relationship between sleep and exercise. CONCLUSIONS: Further prospective research using an objective measure of exercise is warranted to confirm or refute the nature of the relationship between exercise and sleep disturbance in individuals diagnosed with CRC transitioning off first-line treatment. PMID- 29470706 TI - Reduced proliferation capacity of lung cells in chronic obstructive pulmonary disease. AB - BACKGROUND AND OBJECTIVES: The prevalence of chronic obstructive pulmonary disease (COPD) and lung emphysema increases with age and both lung diseases are again risk factors for lung cancer. Since a reduced capacity of fibroblasts for proliferation is a good indicator of tissue aging, we studied the cell proliferation of lung fibroblasts from normal and tumor tissue of lung cancer patients depending on lung comorbidities. MATERIAL AND METHODS: Fibroblasts were isolated from tumor and normal lung tissue of 40 lung cancer patients. Cumulative population doubling (CPD) was determined to assess the proliferation capacity, and the PCR technique was used to measure telomere lengths. Since many patients had previously been exposed to severe air pollution, we also studied the effect of air pollution particles on the fibroblast CPD in vitro. RESULTS: Fibroblasts from tumor and normal lung tissue had comparable CPDs; however, the CPD of fibroblasts from both tumor and normal lung tissue was significantly reduced in patients also suffering from COPD. This CPD reduction was highest in COPD patients who had already developed emphysema or were smokers. A significant correlation between CPD and telomere length was identified only for fibroblasts of non-COPD patients. Further studies also showed an adverse effect of air pollution particles on the CPD of lung fibroblasts. CONCLUSION: Lung cells of COPD patients are characterized by accelerated senescence which must have been initiated prior to lung tumorigenesis and cannot depend on telomere shortening only. In addition to smoking as a known risk factor for COPD and lung cancer, air pollution particles could be another reason for the accelerated senescence of lung cells. PMID- 29470705 TI - The effects of high-dose calcitriol and individualized exercise on bone metabolism in breast cancer survivors on hormonal therapy: a phase II feasibility trial. AB - INTRODUCTION: Cancer treatment-induced bone loss (CTIBL) is a long-term side effect of breast cancer therapy. Both calcitriol and weight-bearing exercise improve bone metabolism for osteoporotic patients, but are unproven in a breast cancer population. We used a novel high-dose calcitriol regimen with an individualized exercise intervention to improve bone metabolism in breast cancer survivors. METHODS: We accrued 41 subjects to this open label, 2 * 2 factorial, randomized feasibility trial. Breast cancer survivors were randomized to receive the following: (1) calcitriol (45 micrograms/week), (2) individualized exercise with progressive walking and resistance training, (3) both, or (4) a daily multivitamin (control condition) for 12 weeks. Primary outcomes included changes in biomarkers of bone formation, bone resorption, and the bone remodeling index, a composite measure of bone formation and resorption. Safety measures included clinical and biochemical adverse events. A main effect analysis was used for these endpoints. RESULTS: Hypercalcemia was limited to three grade I cases with no grade >= 2 cases. Among exercisers, 100% engaged in the prescribed aerobic training and 44.4% engaged in the prescribed resistance training. Calcitriol significantly improved bone formation (Cohen's d = 0.64; p < 0.01), resulting in a non-significant increase in the bone remodeling index (Cohen's d = 0.21; p = 31). Exercise failed to improve any of the bone biomarkers. CONCLUSIONS: Both calcitriol and exercise were shown to be feasible and well tolerated. Calcitriol significantly improved bone formation, resulting in a net increase of bone metabolism. Compliance with the exercise intervention was sub-optimal, which may have led to a lack of effect of exercise on bone metabolism. PMID- 29470707 TI - Modeling, simulation, and employing dilution-dialysis microfluidic chip (DDMC) for heightening proteins refolding efficiency. AB - Miniaturized systems based on the principles of microfluidics are widely used in various fields, such as biochemical and biomedical applications. Systematic design processes are demanded the proper use of these microfluidic devices based on mathematical simulations. Aggregated proteins (e.g., inclusion bodies) in solution with chaotropic agents (such as urea) at high concentration in combination with reducing agents are denatured. Refolding methods to achieve the native proteins from inclusion bodies of recombinant protein relying on denaturant dilution or dialysis approaches for suppressing protein aggregation is very important in the industrial field. In this paper, a modeling approach is introduced and employed that enables a compact and cost-effective method for on chip refolding process. The innovative aspect of the presented refolding method is incorporation dialysis and dilution. Dilution-dialysis microfluidic chip (DDMC) increases productivity folding of proteins with the gradual reduction of the amount of urea. It has shown the potential of DDMC for performing refolding of protein trials. The principles of the microfluidic device detailed in this paper are to produce protein on the dilution with slow mixing through diffusion of a denatured protein solution and stepwise dialysis of a refolding buffer flowing together and the flow regime is creeping flow. The operation of DDMC was modeled in two dimensions. This system simulated by COMSOL Multiphysics Modeling Software. The simulation results for a microfluidic refolding chip showed that DDMC was deemed to be perfectly suitable for control decreasing urea in the fluid model. The DDMC was validated through an experimental study. According to the results, refolding efficiency of denaturant Hen egg white lysozyme (HEWL) (EC 3.2.1.17) used as a model protein was improved. Regard to the remaining activity test, it was increased from 42.6 in simple dilution to 93.7 using DDMC. PMID- 29470708 TI - The wound response in fresh-cut lettuce involves programmed cell death events. AB - In this work, the involvement of programmed cell death (PCD) in the wound-induced postharvest browning disorder and senescence in butterhead lettuce (Lactuca sativa L.) fresh-cuts was studied. At the wounded (cut, bruised) sites, rapid browning, loss of chlorophyll and massive cell death, accompanied with accumulation of reactive oxygen species and increased electrolyte leakage occurred in a narrow strip of tissue adjacent the injury. The dead cell morphology (protoplast and nuclei shrinkage) together with the biochemical and physiological changes resembled necrotic PCD type. With a slight delay post wounding, senescence associated with similar cell death features was initiated in distant non-wounded sites. In addition to necrotic PCD, both in wounded and senescing tissue, the appearance of empty cell corpses was observed, indicating that part of the cells might undergo vacuolar PCD (self-digestion of cellular content after vacuole collapse). The wounding-induced local cell death at the primary site of damage suggested that PCD may serve as a mechanism to seal-off the wound by building a physical barrier of dead cells. However, the cell death at sites remote from the wound suggests the distribution of long-distance senescence-inducing wound messengers. Trichomes in unwounded tissue often were the first to show H2O2 accumulation and dead cells; thereafter, the elevated H2O2 and cell death appeared in connecting cells and senescence progressed over larger areas. This suggests that trichomes may contribute to mediating the wound signalling leading to subsequent senescence. Our findings demonstrate that PCD is an integral part of the wound syndrome in fresh-cut lettuce. PMID- 29470709 TI - Arctic, Antarctic, and temperate green algae Zygnema spp. under UV-B stress: vegetative cells perform better than pre-akinetes. AB - Species of Zygnema form macroscopically visible mats in polar and temperate terrestrial habitats, where they are exposed to environmental stresses. Three previously characterized isolates (Arctic Zygnema sp. B, Antarctic Zygnema sp. C, and temperate Zygnema sp. S) were tested for their tolerance to experimental UV radiation. Samples of young vegetative cells (1 month old) and pre-akinetes (6 months old) were exposed to photosynthetically active radiation (PAR, 400-700 nm, 400 MUmol photons m-2 s-1) in combination with experimental UV-A (315-400 nm, 5.7 W m-2, no UV-B), designated as PA, or UV-A (10.1 W m-2) + UV-B (280-315 nm, 1.0 W m-2), designated as PAB. The experimental period lasted for 74 h; the radiation period was 16 h PAR/UV-A per day, or with additional UV-B for 14 h per day. The effective quantum yield, generally lower in pre-akinetes, was mostly reduced during the UV treatment, and recovery was significantly higher in young vegetative cells vs. pre-akinetes during the experiment. Analysis of the deepoxidation state of the xanthophyll-cycle pigments revealed a statistically significant (p < 0.05) increase in Zygnema spp. C and S. The content of UV absorbing phenolic compounds was significantly higher (p < 0.05) in young vegetative cells compared to pre-akinetes. In young vegetative Zygnema sp. S, these phenolic compounds significantly increased (p < 0.05) upon PA and PAB. Transmission electron microscopy showed an intact ultrastructure with massive starch accumulations at the pyrenoids under PA and PAB. A possible increase in electron-dense bodies in PAB-treated cells and the occurrence of cubic membranes in the chloroplasts are likely protection strategies. Metabolite profiling by non targeted RP-UHPLC-qToF-MS allowed a clear separation of the strains, but could not detect changes due to the PA and PAB treatments. Six hundred seventeen distinct molecular masses were detected, of which around 200 could be annotated from databases. These results indicate that young vegetative cells can adapt better to the experimental UV-B stress than pre-akinetes. PMID- 29470710 TI - Risk stratification, genomic data and the law. AB - Risk prediction models have a key role in stratified disease prevention, and the incorporation of genomic data into these models promises more effective personalisation. Although the clinical utility of incorporating genomic data into risk prediction tools is increasingly compelling, at least for some applications and disease types, the legal and regulatory implications have not been examined and have been overshadowed by discussions about clinical and scientific utility and feasibility. We held a workshop to explore relevant legal and regulatory perspectives from four EU Member States: France, Germany, the Netherlands and the UK. While we found no absolute prohibition on the use of such data in those tools, there are considerable challenges. Currently, these are modest and result from genomic data being classified as sensitive data under existing Data Protection regulation. However, these challenges will increase in the future following the implementation of EU Regulations on data protection which take effect in 2018, and reforms to the governance of the manufacture, development and use of in vitro diagnostic devices to be implemented in 2022. Collectively these will increase the regulatory burden placed on these products as risk stratification tools will be brought within the scope of these new Regulations. The failure to respond to the challenges posed by the use of genomic data in disease risk stratification tools could therefore prove costly to those developing and using such tools. PMID- 29470713 TI - Health-related quality of life in patients undergoing cervico-thoracic osteotomies for fixed cervico-thoracic kyphosis in patients with ankylosing spondylitis. AB - PURPOSE: Ankylosing spondylitis (AS) can result in severe cervico-thoracic kyphotic deformity (CTKD). Few studies have addressed the relationship between cervico-thoracic osteotomies in AS and health-related quality of life scores. The aim of this study is to evaluate the impact of cervico-thoracic osteotomy (CTO) on improving quality of life for patients with fixed CTKD. METHODS: A database of all patients who underwent a CTO for CTKD in patients with AS was created. Data entered into the database consisted of patients' demographics and comorbidities, as well as surgical, clinical and radiological data. The outcome measures used in our study were Neck Disability Index (NDI), EuroQol 5D-5L (EQ-5D-5L) and Visual Analogue Scale. We also measured the following radiological parameters: chin-brow to vertical angle (CBVA), C7-Slope, C2-7 angle, Regional Kyphosis Angle, C2-C7 sagittal vertical axis (SVA) and C7-S1 SVA. RESULTS: A total of 13 male patients with AS were included in our study. The mean age was 57.5 years (40-74); and mean follow-up was 37.6 months (12-78). Following the C7-T1 osteotomy (10 Smith Peterson Osteotomies and 3 Pedicle Subtraction Osteotomies), NDI improved from a mean of 65.54 (SD 8.95) to a mean of 22.09 (SD 6.99). The EQ-5D-5L improved from a mean of 0.41 (SD 0.16) to 0.86 (SD 0.088). Pre-operative CBVA was on average 54 degrees (40 degrees -75 degrees ) and post-operative was 7 degrees (2 degrees 12 degrees ). There were no major complications, 1 superficial infection and 5 minor nerve root irritations. CONCLUSIONS: Cervical osteotomy for the management of fixed flexion deformity of cervical spine in ankylosing spondylitis is a safe procedure and can result in restoration of horizontal gaze and sagittal balance with significant improvement of the patient's health-related quality of life.

AB - Chagas disease is an infection caused by the parasite Trypanosoma cruzi that affects millions of people worldwide and is endemic in Latin America. Megacolon is the most frequent complication of the digestive chronic form and happens due to lesions of the enteric nervous system. The neuronal lesions seem to initiate in the acute phase and persist during the chronic phase, albeit the mechanisms involved in this process are still debated. Among the cells of the immune system possibly involved in this pathological process is the mast cell (MC) due to its well-known role in the bi-directional communication between the immune and nervous systems. Using ultrastructural analysis, we found an increased number of degranulated MCs in close proximity to nerve fibers in infected patients when compared with uninfected controls. We also immunostained MCs for the two pro inflammatory molecules tryptase and chymase, the first being also important in neuronal death. The number of MCs immunostained for tryptase or chymase was increased in patients with megacolon, whereas increased tryptase staining was additionally observed in patients without megacolon. Moreover, we detected the expression of the tryptase receptor PAR2 in neurons of the enteric nervous system, which correlated to the tryptase staining results. Altogether, the data presented herein point to the participation of MCs on the denervation process that occurs in the development of T. cruzi-induced megacolon. PMID- 29470712 TI - Diversity of Mammomonogamus (Nematoda: Syngamidae) in large African herbivores. AB - Four species of Mammomonogamus are known from large African herbivores. A recent study demonstrated that a single Mammomonogamus species was shared by both western lowland gorillas (Gorilla gorilla gorilla) and African forest elephants (Loxodonta cyclotis) in Central African Republic, suggesting lower species diversity than previously described in literature. We examined more than 500 fecal samples collected from sympatric African forest elephants, western lowland gorillas, and African forest buffaloes (Syncerus caffer nanus) at four study sites across Central Africa and examined them by coproscopic methods to detect Mammomonogamus eggs, which were found at three of the study sites. Subsequently, sequences of 18S rDNA, 28S rDNA, and cox1 amplified from individual eggs were analyzed. Phylogenetic analyses of both nuclear and mitochondrial DNA revealed two clades: one formed by sequences originating from Gabonese buffaloes and the other comprising gorillas and elephants. The gorilla-elephant clade was further differentiated depending on the locality. We show the existence of at least two distinct species of Mammomonogamus, M. loxodontis in elephants and gorillas and M. nasicola in buffaloes. The available information on Mammomonogamus in African herbivores is reviewed.

AB - PURPOSE: This article presents a surgical solution of a lumbar disc hernia of a pregnant woman focusing on the use of right lateral positioning, spinal anesthesia which has not previously been utilized in third trimester and discusses positioning options, and possible anesthesia methods with the surgical procedure options. METHODS: Case report. RESULTS: A left-sided L5/S1 lumbar disc hernia (verified by magnetic resonance imaging) of a 35-year-old, 32-week pregnant woman with a deteriorating neurological status leading to cauda syndrome was treated successfully by microdiscectomy in right lateral position applying spinal anesthesia. CONCLUSIONS: So far examples are given for almost every possible patient position in the third trimester except the right lateral one. All the previously presented positionings (prone, left lateral) were equally effective regarding the outcome with none being better than another. For left sided lumbar pathologies performed in the third trimester the right lateral position might be an alternative option for easier access. Based on the literature an epidural and general anesthesia can be applied successfully in the third trimester. Spinal anesthesia might be another anesthesia consideration. PMID- 29470715 TI - ISSLS PRIZE IN BIOENGINEERING SCIENCE 2018: dynamic imaging of degenerative spondylolisthesis reveals mid-range dynamic lumbar instability not evident on static clinical radiographs. AB - PURPOSE: Degenerative spondylolisthesis (DS) in the setting of symptomatic lumbar spinal stenosis is commonly treated with spinal fusion in addition to decompression with laminectomy. However, recent studies have shown similar clinical outcomes after decompression alone, suggesting that a subset of DS patients may not require spinal fusion. Identification of dynamic instability could prove useful for predicting which patients are at higher risk of post laminectomy destabilization necessitating fusion. The goal of this study was to determine if static clinical radiographs adequately characterize dynamic instability in patients with lumbar degenerative spondylolisthesis (DS) and to compare the rotational and translational kinematics in vivo during continuous dynamic flexion activity in DS versus asymptomatic age-matched controls. METHODS: Seven patients with symptomatic single level lumbar DS (6 M, 1 F; 66 +/- 5.0 years) and seven age-matched asymptomatic controls (5 M, 2 F age 63.9 +/- 6.4 years) underwent biplane radiographic imaging during continuous torso flexion. A volumetric model-based tracking system was used to track each vertebra in the radiographic images using subject-specific 3D bone models from high-resolution computed tomography (CT). In vivo continuous dynamic sagittal rotation (flexion/extension) and AP translation (slip) were calculated and compared to clinical measures of intervertebral flexion/extension and AP translation obtained from standard lateral flexion/extension radiographs. RESULTS: Static clinical radiographs underestimate the degree of AP translation seen on dynamic in vivo imaging (1.0 vs 3.1 mm; p = 0.03). DS patients demonstrated three primary motion patterns compared to a single kinematic pattern in asymptomatic controls when analyzing continuous dynamic in vivo imaging. 3/7 (42%) of patients with DS demonstrated aberrant mid-range motion. CONCLUSION: Continuous in vivo dynamic imaging in DS reveals a spectrum of aberrant motion with significantly greater kinematic heterogeneity than previously realized that is not readily seen on current clinical imaging.

PMID- 29470716 TI - Denosumab: a potential treatment option for aneurysmal bone cyst of the atlas. AB - PURPOSE: Aneurysmal bone cysts (ABCs) of spine are conventionally treated with en bloc resection or intralesional excision/curettage and reconstruction or filling of defects with bone cement. For the treatment of upper cervical ABCs, en-bloc resections are often not desirable considering the risk/benefit ratio while the risk of recurrence after intralesional excision is high. Hence, alternative management options are often necessary. We describe our clinical experience with one such treatment alternative-denosumab for the treatment of ABC of Atlas. METHODS AND RESULTS: We present a case of 16-year-old boy who presented with neck pain and restriction of neck movements. A large lytic lesion with multiple fluid fluid interfaces involving vertebral arch of atlas was identified on further imaging. There was destruction of right lateral mass and the lesion was found encasing the right vertebral artery. Core needle biopsy confirmed the diagnosis of ABC. With no visible CT response after first session of intra-lesional injection of Calcitonin and Methylprednisolone, the patient was treated with denosumab (120 mg SC once-a-month) for a period of 12 months. His symptoms resolved within 7 months of onset of treatment and serial CT scans over 12-month treatment period showed complete ossification of the lesion. Further there was no evidence of recurrence at 12 months after completion of treatment. CONCLUSION: Our case report contributes to the accruing evidence on the effectiveness of denosumab for the treatment of spinal ABCs. However, long-term safety, risk of recurrence, optimal duration of treatment and consistency of denosumab are yet to be determined. PMID- 29470717 TI - Risk of central nervous system defects in offspring of women with and without mental illness. AB - We sought to determine the relationship between maternal mental illness and the risk of having an infant with a central nervous system defect. We analyzed a cohort of 654,882 women aged less than 20 years between 1989 and 2013 who later delivered a live born infant in any hospital in Quebec, Canada. The primary exposure was mental illness during pregnancy or hospitalization for mental illness before pregnancy. The outcomes were neural and non-neural tube defects of the central nervous system in any offspring. We computed risk ratios (RR) and 95% confidence intervals (CI) for the association between mental disorders and risk of central nervous system defects in log-binomial regression models adjusted for age at delivery, total parity, comorbidity, socioeconomic deprivation, place of residence, and time period. Maternal mental illness was associated with an increased risk of nervous system defects in offspring (RR 1.76, 95% CI 1.64 1.89). Hospitalization for any mental disorder was more strongly associated with non-neural tube (RR 1.84, 95% CI 1.71-1.99) than neural tube defects (RR 1.31, 95% CI 1.08-1.59). Women at greater risk of nervous system defects in offspring tended to be diagnosed with multiple mental disorders, have more than one hospitalization for mental disease, or be 17 or older at first hospitalization. A history of mental illness is associated with central nervous system defects in offspring. Women hospitalized for mental illness may merit counseling at first symptoms to prevent central nervous system defects at pregnancy. PMID- 29470718 TI - Prediction of Human Pharmacokinetics of Ulixertinib, a Novel ERK1/2 Inhibitor from Mice, Rats, and Dogs Pharmacokinetics. AB - BACKGROUND AND OBJECTIVES: Ulixertinib (BVD-523) is a novel and selective reversible inhibitor of ERK1/ERK2. The primary objectives of the study were to evaluate the pharmacokinetics of ulixertinib in mice, rats, and dogs followed by prediction of human pharmacokinetic profile by allometric equations with/without correction factors. METHODS: Oral and intravenous pharmacokinetic profiles of ulixertinib were generated in mice, rats, and dogs. The human intravenous pharmacokinetics profiles [volume of distribution (Vss) and clearance (CL)] were predicted employing simple allometry and using correction factors [maximum life span potential (MLP) and brain weight (BW)]. Pharmacokinetic data obtained from dogs were used to simulate human oral profile [area under the curve (AUC) and maximum plasma concentrations (Cmax)]. RESULTS: Post-intravenous administration the CL was moderate in dogs (15.5 mL/min/kg) and low in mice (6.24 mL/min/kg) and rats (1.67 mL/min/kg). Vss was 0.56, 0.36, and 1.61 L/kg in mice, rats, and dogs, respectively. The half-life (t1/2) of ulixertinib ranged between 1.0 and 2.5 h across the animal species. Following oral administration ulixertinib attained maximum concentration in plasma (Tmax) within 0.50-0.75 h in mice and rats, indicating that absorption was rapid; however, in dogs, Tmax attained at 2 h. Absolute oral bioavailability in mice and rats was > 92%; however, in dogs, it was 34%. By different allometric approaches, simple method and brain weight correction factor shown clear improvement in the prediction efficiency of allometric scaling for Vss (1.34-1.70 L/kg) and CL (4.18-6.09 mL/min/kg), respectively, comparing with the MLP method and simple method for CL. Similarly, simulation of oral human profile was attained from scaled values and dog data to predict reported human profile (AUC and Cmax). CONCLUSIONS: The derived pharmacokinetic parameters (AUC and Cmax at 600 mg dose) and simulated plasma concentration-time profiles of ulixertinib in humans were predicted with good confidence by allometric approach. PMID- 29470719 TI - Seasonal and spatial variation of reservoir water quality in the southwest of Ethiopia. AB - This research investigated the spatiotemporal variation of water quality in the Gilgel Gibe reservoir, Ethiopia, using physicochemical water quality parameters. Nonparametric tests and multivariate statistical techniques were used to evaluate data sets measured during dry and rainy seasons. Electrical conductivity (EC), pH, biochemical oxygen demand (BOD5), total phosphorus (TP), total nitrogen (TN), nitrate (NO3-), total dissolved solids (TDSs), and total suspended solids (TSSs) were all significantly different among seasons (Mann-Whitney U test, p < 0.01). In addition, principal component analysis distinguished dry season samples from wet season samples. The dry season was positively associated with EC, pH, TP, TN, NO3-, TDS, and TSS and negatively associated with BOD5. The wet season was in contrast associated with high values of turbidity, soluble reactive phosphorus (SRP), water temperature, and dissolved oxygen (DO). Within the reservoir, spatial variation was observed for some of the water quality parameters, with significant difference at p = < 0.05. Overall, high nutrient concentrations suggest eutrophic conditions, likely due to high nutrient loading from the watershed. Levels of TSS, attributed to inputs from tributaries, have been excessive enough to inhibit light penetration and thus have a considerable impact on the aquatic food web. Our findings indicate that the reservoir is at high risk of eutrophication and siltation, and hence, urgent action should target the planning and implementation of integrated watershed management for this and similar reservoirs in the region. PMID- 29470721 TI - Association of ischemic stroke with ankylosing spondylitis: a nationwide longitudinal cohort study. AB - BACKGROUND: The purpose of this nationwide age- and sex-matched longitudinal follow-up study was to investigate the risk of developing ischemic stroke in ankylosing spondylitis (AS). METHODS: The data in this study, spanning from January 1, 2010 to December 31, 2014, was obtained from a database maintained by the Korean National Health Insurance Service. A total of 12,988 patients with a diagnosis of AS were enrolled. The control group consisted of 64,940 age-sex stratified matching subjects without AS. The 6year ischemic stroke incidence rate for each group was calculated using the Kaplan-Meier method. Cox proportional hazards regression analysis was used to estimate the hazard ratio of ischemic stroke. RESULTS: During the follow-up period, 73 patients (0.56%) in the AS group and 250 patients (0.38%) in the control group developed ischemic stroke (p = 0.0041). The hazard ratio of ischemic stroke in the AS group was 1.46 (95% confidence interval [95% CI], 1.13-1.90) after adjusting for age and sex. The adjusted hazard ratio of ischemic stroke in the AS group was 1.35 (95% CI, 1.04 1.75) after controlling for demographics and comorbid medical disorders. According to subgroup analysis, in female and diabetes and non-hypertension and dyslipidemia subgroups, ischemic stroke incidence rates were significantly higher in AS patients than those in control group. CONCLUSION: Our nationwide longitudinal study suggests an increased risk of ischemic stroke in AS patients. PMID- 29470720 TI - Diagnostic Tools for Inborn Errors of Human Immunity (Primary Immunodeficiencies and Immune Dysregulatory Diseases). AB - PURPOSE OF REVIEW: The purpose of this review is to provide an overview of diagnostic testing in primary immunodeficiency and immune dysregulatory disorders (PIDDs), particularly focusing on flow cytometry and genetic techniques, utilizing specific examples of PIDDs. RECENT FINDINGS: Flow cytometry remains a vital tool in the diagnosis and monitoring of immunological diseases. Its utility ranges from cellular analysis and specific protein quantitation to functional assays and signaling pathway analysis. Mass cytometry combines flow cytometry and mass spectrometry to dramatically increase the throughput of multivariate single cell analysis. Next-generation sequencing in combination with other molecular techniques and processing algorithms has become more widely available and identified the diverse and heterogeneous genetic underpinnings of these disorders. As the spectrum of disease is further clarified by increasing immunological, genetic, and epigenetic knowledge, the careful application of these diagnostic tools and bioinformatics will assist not only in our understanding of these complex disorders, but also enable the implementation of personalized therapeutic approaches for disease management. PMID- 29470722 TI - Can anodised zirconium implants stimulate bone formation? Preliminary study in rat model. AB - The mechanical properties and good biocompatibility of zirconium and some of its alloys make these materials good candidates for biomedical applications. The attractive in vivo performance of zirconium is mainly due to the presence of a protective oxide layer. In this preliminary study, the surface of pure zirconium modified by anodisation in acidic media at low potentials to enhance its barrier protection given by the oxides and osseointegration. Bare, commercially pure zirconium cylinders were compared to samples anodised at 30 V through electrochemical tests and scanning electron microscopy (SEM). For both conditions, in vivo tests were performed in a rat tibial osteotomy model. The histological features and fluorochrome-labelling changes of newly bone formed around the implants were evaluated on the non-decalcified sections 63 days after surgery. Electrochemical tests and SEM images show that the anodisation treatment increases the barrier effect over the material and the in vivo tests show continuous newly formed bone around the implant with a different amount of osteocytes in their lacunae depending on the region. There was no significant change in bone thickness around either kind of implant but the anodised samples had a significantly higher mineral apposition, suggesting that the anodisation treatment stimulates and assists the osseointegration process. We conclude that anodisation treatment at 30 V can stimulate the implant fixation in a rat model, making zirconium a strong candidate material for permanent implants. PMID- 29470723 TI - Cyclin-dependent kinase 4/6 inhibitors as first-line treatment for post menopausal metastatic hormone receptor-positive breast cancer patients: a systematic review and meta-analysis of phase III randomized clinical trials. AB - BACKGROUND: To compare the efficacy and toxicity of the combination of cyclin dependent kinase 4/6 (CDK 4/6) inhibitors and nonsteroidal aromatase inhibitors (AI) versus AI alone as first-line therapy for patients with advanced hormone receptor-positive breast cancer. MATERIALS AND METHODS: Phase III randomized clinical trials (RCT) were identified after a systematic review of electronic databases. A random-effect model was used to determine the pooled hazard ratio (HR) for progression-free survival (PFS) using the inverse-variance method. The Mantel-Haenszel method was used to calculate the pooled odds ratio (OR) for overall response, clinical benefit rate and treatment-related side effects. Heterogeneity was measured using the tau-squared and I2 statistics. RESULTS: After a systematic search, three phase III RCT (n = 1827) were included. The use of CDK 4/6 inhibitors (abemaciclib, palbociclib, and ribociclib) in combination with an AI was significantly associated with longer PFS compared to the use of letrozole or anastrozole alone (HR: 0.57; 95% CI 0.50-0.65; p < 0.00001), with no significant heterogeneity among trials. Similarly, overall response rate and clinical benefit rate were higher for patients who received the combination therapy than for patients allocated to AI alone. Grade 3 or higher treatment related side effects were more frequently reported for patients who received CDK 4/6 inhibitors (OR: 7.51; 95% CI 6.01-9.38; p < 0.00001), these included mainly neutropenia, leukopenia and anemia. CONCLUSION: The addition of CDK 4/6 inhibitors (either abemaciclib, palbociclib, or ribociclib) to an AI (anastrozole or letrozole) significantly improved PFS, overall response rate, and clinical benefit rate in comparison with a nonsteroidal AI alone. PMID- 29470724 TI - Physico-chemical characteristics of gamma-irradiated gelatin. AB - This article reports the effects of gamma irradiation (dose ranges 0.1-10 kGy from 60Co source) on the characteristics of solid gelatin and the physico mechanical, microstructural and bioactive properties of the scaffold prepared from irradiated gelatin solution. FTIR, intrinsic viscosity, bloom strength, thermal properties, SEM, tensile properties, water uptake ability and antimicrobial activities of non-irradiated and irradiated solid gelatin and its scaffolds were investigated. The detailed experimental results for the solid gelatin demonstrated that 1 kGy gamma-irradiated samples showed higher intrinsic viscosity, enhanced thermal stability and bloom strength than other irradiated samples. Furthermore, the scaffold thus prepared from irradiated and non irradiated gelatin also revealed that 1 kGy samples showed the highest tensile strength and modulus with good water resistivity than other irradiated and non irradiated samples. In addition to the physico-mechanical properties, 1 kGy scaffolds have also exhibited the highest resistivity towards microbial growth that can have potentiality as scaffold in biomedical sector. The enhanced functional and bioactive properties at low irradiation doses (1 kGy) may occurred due to an initial breaking of hydrogen bonds of polypeptide chains in gelatin molecules that indicated by the shift of amide A, I and II peaks to higher wave numbers in FTIR. This enhancement resulted probably due to the domination of crosslinking over degradation at 1 kGy. It was also observed that 1 kGy gamma radiation-induced crosslinking has lowered the hydrophilicity by decreasing water uptake and mean pore diameter of the interconnected porous structures of gelatin. PMID- 29470725 TI - Recent advances in therapeutic strategies for unresectable or metastatic melanoma and real-world data in Japan. AB - New therapeutic strategies including immunotherapy and selective molecular target inhibitors have brought about a new era in the treatment of patients with advanced melanoma. In Japan, the immune checkpoint inhibitors ipilimumab, nivolumab and pembrolizumab, the BRAF inhibitor (BRAFi) vemurafenib, dabrafenib and MEK inhibitor (MEKi) trametinib have been available for the treatment of unresectable and metastatic melanoma. The BRAFi + MEKi combination shows high response rates (60-70%) and rapid response induction associated with symptom control, with a progression-free survival of 12 months. Nivolumab and pembrolizumab offer moderate response rates (30-40%) and long survival (3- to 5 year survival: 30-50%). In Japan, treatment options for the first-line setting frequently include nivolumab or pembrolizumab monotherapy and BRAFi + MEKi combinations (for patients with BRAF-mutant melanoma). Ipilimumab is included in the second-line setting, and the nivolumab + ipilimumab combination has not been approved yet in Japan. Although these medications have demonstrated impressive efficacy, the clinical trials and real-world data have shown that the clinical benefit is not fully satisfactory. We have to carefully manage a new class of adverse events due to these medicines. Moreover, biomarkers are emerging with which we can identify a population that would experience more benefits without severe adverse events. PMID- 29470726 TI - Polystyrene surface modification using excimer laser and radio-frequency plasma: blood compatibility evaluations. AB - Biomaterial surface modification is an efficient method to improve and control blood component-material interactions. In the present study, two different methods (ArF excimer laser irradiation and radio-frequency (RF) plasma treatment) were applied in separate procedures to create a vast range of physicochemical characteristics on the surface of polystyrene (PS) and investigate their effects on blood compatibility of treated surfaces. Atomic force microscopy (AFM) and Fourier transmission infrared analysis were applied to study the morphology and chemical characteristics of treated samples in comparison with those of the untreated PS. Contact angle and surface tension measurements with two different solvents were used to evaluate the wettability and surface energy of the treated PS films. The effect of the physicochemical properties of the PS surface on blood compatibility was investigated using lactate dehydrogenase (LDH) method. AFM studies showed that after laser treatment, some distinctive nanostructures are created on the surface of PS. The data from contact angle measurements demonstrated that ArF excimer laser irradiation and RF plasma treatment created surfaces with a vast range of properties in the wettability point of view. The LDH results revealed that after surface modification by laser irradiation and plasma treatment, blood compatibility of PS films was enhanced. In addition, these results offered that the most blood compatible samples were those which irradiated with 5 pulses of laser and the one treated 4 minutes in oxygen plasma. PMID- 29470727 TI - pH-responsive stealth micelles composed of cholesterol-modified PLA as a nano carrier for controlled drug release. AB - Present research is a preliminary report on the novel pH-responsive micelles based on an amphiphilic brush copolymer P(PEGMA)-b-P(DMAEMA-co-CPLAMA) used as the promising drug carrier. The copolymer was synthesized using cholesteryl poly(L-lactic acid) methacrylate (CPLAMA), poly(ethylene glycol) monomethyl ether methacrylate (PEGMA) and 2-(dimethylamino)ethyl methacrylate (DMAEMA) with appropriate hydrophobic/hydrophilic ratios via atom transfer radical polymerization. The copolymer compositions were determined by 1H NMR. The synthesized copolymer self-assembled into nano-scale micelles capable of encapsulating hydrophobic model drug naproxen in their hydrophobic cores in aqueous solutions. pH sensitivity and self-assembly behaviors of copolymer were studied by UV-vis transmittance, fluorescence spectroscopy, transmission electron microscopy (TEM) and dynamic light scattering. The results showed that the copolymer had high pH responsivity with a phase transition pH around pH 6.2. The critical micelle concentrations at pH 6.5 were found about 2.4 mg L-1. The stable and small micelles were obtained at pH 5.5-6.5. Upon increasing pH higher than 7, the single micelles further assembled into the micellar aggregates. TEM images of copolymer micelles showed that the micelles are spherical in shape with the mean diameter of 152 nm at pH 6.2. In vitro release study of naproxen-loaded micelles with about 44 % loading efficiency and 8 % loading capacity was performed using dialysis method in phosphate-buffered solution at 37 degrees C. Release study implied that the proposed brush copolymer could produce stable nano-carriers with controllable drug release at the target sites (pH 5.5-7). PMID- 29470728 TI - Fecal incontinence after transanal endoscopic microsurgery. AB - PURPOSE: Transanal endoscopic microsurgery (TEM) procedure could potentially influence the development of fecal incontinence later in life. The aim of our study was to assess long-term functional outcomes after TEM and to determine possible variables related to incontinence. METHODS: Patients, enrolled in a prospectively collected TEM operation database, were interviewed using a postal questionnaire. The questionnaire consisted of EuroQol (EQ)-5D-5L quality of life questionnaire, Wexner fecal incontinence grading scale, and additional questions about other perianal operations and obstetric history for women. We divided patients into two groups: no or minor fecal incontinence (Wexner score of 2 and less) and non-minor incontinence (Wexner score of 3 or more). RESULTS: One hundred thirty-two patients were included in the study. Patients' median follow up time was 96 (12-168) months from their operation. Thirty-eight patients (28.8%) reported Wexner score of 3 or more, and they reported significantly worse quality of life in all tested life spheres. They were older at the time of the operation (63 (18-82) vs. 68 (50-89) years; p = 0.004), underwent longer operations (50 (10-140) vs. 60 (15-210) min; p = 0.017), and more often were operated for malignant lesions (17 (18.3%) vs. 14 (36.8%); p = 0.040). Older age at the time of operation was an independent risk factor in multivariate model (OR 1.057, 95% CI 1.010-1.106; p = 0.016). CONCLUSIONS: Fecal incontinence after TEM is more common than thought previously, resulting in significantly impaired quality of life. Older age at the time of operation was an independent risk factor for developing significant fecal incontinence. PMID- 29470729 TI - Retromesenteric course of the middle colic artery-challenges and pitfalls in D3 right colectomy for cancer. AB - BACKGROUND: The middle colic artery (MCA) is of crucial importance in abdominal surgery, for laparoscopic or open right and transverse colectomies. Against this background, a high number of reports concerning anatomical variations of the MCA have been published intended to contribute to the improvement of operative techniques for the treatment of colon cancer. Despite this extensive literature, briefly reviewed in the present paper, a course of the MCA posterior to the superior mesenteric vein, called a retromesenteric trajectory, has been related to only once, to the best of our knowledge. METHODS: A total series of 507 patients included in two prospective trials concerning laparoscopic or open right colectomy for cancer between 2011 and 2017 are reported. The investigation included preoperative or postoperative multidetector-computed tomography angiography. RESULTS: We found four (0.79%) cases of retromesenteric MCA. They all underwent meticulous image analysis with mesenteric vessels' road mapping, detailed morphometry, and surgical validation which revealed that, apart from their course, those cases did not differ significantly from the rest of the series. CONCLUSION: This paper therefore documents the worth-knowing behavior causing considerable confusion for the operating surgeon unaware of the abnormality and shows its concrete impact on patient-tailored surgical practice, in particular for laparoscopic D3 colectomy (including the "uncinated process first" approach). PMID- 29470730 TI - Sacral nerve stimulation versus percutaneous tibial nerve stimulation for faecal incontinence: a systematic review and meta-analysis. AB - AIMS: Percutaneous tibial nerve stimulation (PTNS) and sacral nerve stimulation (SNS) are both second-line treatments for faecal incontinence (FI). To compare the clinical outcomes and effectiveness of SNS versus PTNS for treating FI in adults. METHOD: A literature search of MEDLINE, Embase, Science Citation Index Expanded and Cochrane was performed in order to identify studies comparing SNS and PTNS for treating FI. A risk of bias assessment was performed using The Cochrane Collaboration's risk of bias tool. A random effects model was used for the meta-analysis. RESULTS: Four studies (one randomised controlled trial and three nonrandomised prospective studies) reported on 302 patients: 109 underwent SNS and 193 underwent PTNS. All included studies noted an improvement in symptoms after treatment, without any significant difference in efficacy between SNS and PTNS. Meta-analysis demonstrated that the Wexner score improved significantly with SNS compared to PTNS (weighted mean difference 2.27; 95% confidence interval 3.42, 1.12; P < 0.01). Moreover, SNS was also associated with a significant reduction in FI episodes per week and a greater improvement in the Fecal Incontinence Quality of Life coping and depression domains, compared to PTNS on short-term follow-up. Only two studies reported on adverse events, reporting no serious adverse events with neither SNS nor PTNS. CONCLUSION: Current evidence suggests that SNS results in significantly improved functional outcomes and quality of life compared to PTNS. No serious adverse events were identified with either treatment. Further, high-quality, multi-centre randomised controlled trials with standardised outcome measures and long-term follow-up are required in this field. PMID- 29470732 TI - Thermal, mechanical, and moisture absorption properties of egg white protein bioplastics with natural rubber and glycerol. AB - Petroleum-based plastics have many drawbacks: the large amount of energy required to produce the plastic, the waste generated as a result of plastic production, and the accumulation of waste due to slow degradation rate. It is because of these negative attributes of conventional plastic use that attention is being focused on environmentally friendly plastics from alternative sources. Albumin protein provides one possible source of raw material, with inherent antimicrobial properties that may make it suitable for medical applications. We conducted this study to investigate the various bioplastic properties of the albumin with the use of three plasticizers - water, glycerol, and natural rubber latex. Based on results, 75:25 albumin-water, 75:25 albumin-glycerol, and 80:20 albumin-natural rubber were the best blending ratios for each plasticizer for a subsequent time study to determine water stability, with the 80:20 albumin-natural rubber blend ratio having possessed the best thermal, tensile, and viscoelastic properties overall. PMID- 29470731 TI - Sacral neuromodulation versus personalized conservative treatment in patients with idiopathic slow-transit constipation: study protocol of the No.2-trial, a multicenter open-label randomized controlled trial and cost-effectiveness analysis. AB - PURPOSE: The evidence regarding the (cost-)effectiveness of sacral neuromodulation (SNM) in patients with therapy-resistant idiopathic slow-transit constipation is of suboptimal quality. The Dutch Ministry of Health, Welfare and Sports has granted conditional reimbursement for SNM treatment. The objective is to assess the effectiveness, cost-effectiveness, and budget impact of SNM compared to personalized conservative treatment (PCT) in patients with idiopathic slow-transit constipation refractory to conservative treatment. METHODS: This study is an open-label, multicenter randomized controlled trial. Patients aged 14 to 80 with slow-transit constipation, a defecation frequency (DF) < 3 per week and meeting at least one other Rome-IV criterion, are eligible. Patients with obstructed outlet, irritable bowel syndrome, bowel pathology, or rectal prolapse are excluded. Patients are randomized to SNM or PCT. The primary outcome is success at 6 months (DF >= 3 a week), requiring a sample size of 64 (alpha = 0.05, beta = 0.80, 30% difference in success). Secondary outcomes are straining, sense of incomplete evacuation, constipation severity, fatigue, constipation specific and generic quality of life, and costs at 6 months. Long-term costs and effectiveness will be estimated by a decision analytic model. The time frame is 57 months, starting October 2016. SNM treatment costs are funded by the Dutch conditional reimbursement program, research costs by Medtronic. CONCLUSIONS: The results of this trial will be used to make a final decision regarding reimbursement of SNM from the Dutch Health Care Package in this patient group. TRIAL REGISTRATION: This trial is registered at clinicaltrials.gov , identifier NCT02961582, on 12 October 2016. PMID- 29470733 TI - Optimization of monomethoxy poly(ethylene glycol) grafting on Langerhans islets capsule using response surface method. AB - Langerhans islet transplantation is a much less invasive approach compared with the pancreas transplantation to 'cure' diabetes. However, destruction of transplanted islets by the immune system is an impediment for a successful treatment. Chemical grafting of monomethoxy poly(ethylene glycol) onto pancreatic islet capsule is a novel approach in islet immunoisolation. The aim of this study was to determine an optimized condition for grafting of monomethoxy poly(ethylene glycol) succinimidyl propionate (mPEG-SPA) on islets capsule. Independent variables such as reaction time, the percentage of longer mPEG in the mixture, and polymer concentration were optimized using a three-factor, three-level Box Behnken statistical design. The dependent variable was IL-2 (interleukin-2) secretion of lymphocytes co-cultured with PEGylated or uncoated control islets for 7 days co-culturing. A mathematical relationship is obtained which explained the main and quadratic effects and the interaction of factors which affected IL-2 secretion. Response surface methodology predicted the optimized values of reaction time, the percentage of longer mPEG in the mixture, and polymer concentration of 60 min to be 63.7% mPEG10 and 22 mg/mL, respectively, for the minimization of the secreted IL-2 as response. Islets which were PEGylated at this condition were transplanted to diabetic rats. The modified islets could survive for 24 days without the aid of any immunosuppressive drugs and it is the longest survival date reported so far. However, free islets (unmodified islets as control) are completely destroyed within 7 days. These results strongly suggest that this new protocol provides an effective clinical means of decreasing transplanted islet immunogenicity.

AB - For the purposes of this study, hydroxyapatite (HA)-Al2O3-TiO2 nanobiomaterial with significant surface properties and biocompatibility capable of forming surface apatite was fabricated by cold-press and sintering method. Samples were examined for hardness and porosity. The results showed that in terms of hardness and porosity, sample A (50 wt% TiO2-30 wt% HA-20 wt% Al2O3) was superior to sample B (30 wt% TiO2-50 wt% HA-20 wt% Al2O3), and also the density of nanobiomaterial was close to natural bone density. Bioactivity of the samples in a simulated body fluid (SBF) was investigated. Then, after immersing the samples in SBF solution for a period of 7 days, sample B exhibited greater ability to form calcium phosphate compounds on the surface as compared to sample A. In addition, in vitro studies showed that MG-67 osteoblast-like cells attached and spread on the samples surface. The results showed that cells proliferated in greater numbers on the sample B as compared to the sample A. Finally, X-ray diffraction, scanning electron microscopy, and energy-dispersive X-ray analysis were performed to identify phases, study microstructure, and determine percentage of elements, respectively. The results revealed that considering their different properties, both nanobiomaterials can be used in medical applications.

AB - BACKGROUND: In low-resource countries, a suture repair is still in common use due to the limited access to commercial mesh implants. The search for less expensive alternatives to the synthetic meshes has led to using mosquito nets. Sterilized mosquito net appears to be a low-cost and commonly available product that closely resembles commercially available meshes. However, the extent to which sterilization alters the structure of mosquito nets is still unknown. The aim of this research was to assess the effects of different sterilization types on physico-mechanical properties of mosquito nets. MATERIALS AND METHODS: Nine different polymers were analyzed (six mosquito nets from low-resource countries, one European net, and two commercial meshes). The analyzed parameters included: polymer type, net surface area, fiber diameter, net thickness, mesh weight, pore size, tensile strength, and tear force. The measurements were taken before sterilization, after sterilization at 121 and at 134 degrees C. RESULTS: Sterilization altered net surface and pore size, but did not significantly alter the single fiber diameter, weave of filaments, or net thickness. Steam sterilization did not affect the tensile strength or tear force. CONCLUSIONS: The reduction of the mosquito net surface area by more than 40% due to sterilization at 121 degrees C, results in a loss of macroporous structure, turning the mesh into hard, shrunken, non-pliable masses. Sterilization at 134 degrees C causes some mosquito nets to melt and completely destroys their porous structure. Maximum pressure in the abdominal cavity is higher than the tensile strength and tear force of some locally available mosquito nets; therefore, these nets should not be used.

AB - Iloprost (ILO) is employed intravenously for the treatment of severe Raynaud phenomenon (RP) and digital ulcers (DU) in systemic sclerosis (SSc). The aim of this study was to evaluate the safety and tolerability of the intravenous treatment with ILO in different phases of SSc. Eighty-one consecutive non selected SSc patients, all on nifedipine, with moderate RP, treated with ILO infusion, were retrospectively evaluated. Patients were sub classified according to the edematous or fibrotic/atrophic cutaneous phase of the disease. ILO was infused with a progressive increase of the dosage up to the achievement of patient's tolerance, 1 day/week. In cases of slower infusion regimen due to adverse events (AE) at the beginning of the administration, patients received a lower dose of the drug (not possible to quantify precisely the final cumulative dosage). 16/81 SSc patients presented digital edema, 5 developed diarrhea, and 9 developed transient hypotension during the infusion at 20 ml/h that ameliorated when the drug was withdrawn. Moreover, 10/16 edematous patients experienced significant and painful digital swelling, unlike patients in the fibrotic group (p < 0.0001); 11/16 patients reported flushing and 7/16 headache, always controlled with dose tapering below 10 ml/h. In the atrophic/fibrotic phase patients (65/81), 10 developed diarrhea and 24 hypotension at infusion rate of 20 ml/h that led to temporary withdrawal of the drug. When ILO was restarted and kept below 10 ml/h, no side effects were experienced. 23/65 patients experienced flushing and 8/65 headache, all controlled with infusion reduction below 10 ml/h. In these patients, adverse events were significantly less frequent than in the edematous group (p = 0.023 and p = 0.008, respectively). Our data suggest that calcium channel blockers should be transitorily stopped while using ILO and that a pre-treatment approach might reduce or control adverse events. In patients with digital edema, ILO infusion should be carefully employed after the evaluation of patient's drug tolerance.

Although the prevalence of diabetes is high, the factors associated with it in PsA are poorly understood. We aimed to analyse the prevalence of type II diabetes and diabetes-associated factors in a hospital-based population with PsA. This cross-sectional study included 340 consecutive patients attended in a tertiary care hospital. The prevalence of diabetes was compared to that of 600 outpatients without inflammatory conditions. To analyse diabetes-associated factors, odds ratio (OR) values were calculated by conditional logistic regression analysis. Significant variables in the univariate analysis were then introduced in a multivariate analysis with a backward stepwise approach. Diabetes was more prevalent among PsA patients (13.8 vs. 5%, OR 2.8, 95% CI: 1.7-4.3, p < 0.0001). Diabetes-associated factors in the univariate analysis (p < 0.05) were the following: an age of onset of psoriasis > 40 years, an age of onset of arthritis > 40 years, a low educational level, family history of psoriasis, pustular psoriasis, high number of swollen joints during follow-up, hypertension, dyslipidemia, obesity, and cardiovascular events. After controlling for several confounders, diabetes was significantly associated with late-onset psoriasis (OR 8.2, 95% CI: 1.9-12.4, p = 0.002) and hypertension (OR 7.5, 95% CI: 1.5-13.3, p = 0.008). Diabetes risk should be carefully evaluated in patients with PsA whose psoriasis begins after 40 years. PMID- 29470739 TI - The association between osteoarthritis and sleep duration in Koreans: a nationwide cross-sectional observational study. AB - Osteoarthritis (OA) causes chronic pain, physical disability, and mental health deterioration and reduces the quality of life of patients. Sleep is an important factor in the recovery, and adequate sleep is important for quality of life. Several features of patients with OA can affect sleep time, and sleep also affects OA. We investigated the relationship between OA and sleep duration. Data for 2010-2012 were collected from the Korea National Health and Nutrition Examination Survey. We included 11,540 participants (4915 men and 6625 women). Patients with OA were defined as participants with knee/hip joint pain and radiographic changes of the knee/hip joints. Sleep time was divided into 4 sections as follows: (1) 0-3 h, (2) 4-5 h, (3) 6-7 h, and (4) >= 8 h. Sleep time of 6 and 7 h was the most frequent and set as the reference time. In the multiple logistic regression model, the patients who slept for 0-3 and 4-5 h had odds ratios (ORs) of 2.28 (95% confidence interval [CI] 1.14-4.55) and 1.38 (95% CI 1.01-1.89) for men and 1.63 (95% CI 1.19-2.24) and 1.26 (95% CI 1.08-1.47) for women, respectively, for having OA. The prevalence of OA was lowest in the participants who had 6-7 h of sleep and progressively increased with shorter sleep time. Thus, sleep duration was significantly associated with OA.

AB - An experiment was conducted to study the effects of supplementing sprouts of pulses on performance, carcass variables, immune responses, and anti-oxidant variables in broiler chicken (day 1 to 6 weeks of age) reared during summer season in tropical region. Sprouts of black gram (BG, Vigna mungo), green gram (GG, Vigna radiata), and wild gram (WG, Vigna trilobata) were produced by soaking the pulses in water for 16 h and incubating at 37 degrees C for 24 h. Total phenolic content in sprouts of WG, BG, and GG was 102, 96.1, and 79.2 mg GAE/g, respectively, while the anti-radical activity in the sprouts was 61, 58, and 52%, respectively. A total of 200-day-old broiler male chicks were equally and randomly distributed in to 4 groups, each having 10 replicates of 5 chicks and housed in battery brooders in open-sided poultry house. Each of these groups was fed sprouts of BG, GG, or WG at 5% of feed intake, while the control group without feeding sprouts was kept for comparison. The trial was conducted during mid summer season (April and May, 2017). Feed conversion ratio (FCR) was reduced (P < 0.05) in broilers fed sprouted pulses compared to the control group at day 21. However, the body weight gain and FCR at 42 days of age, slaughter variables, and immune responses were not affected due to feeding of sprouted pulses. Feeding of sprouts significantly (P < 0.05) reduced lipid peroxidation and increased (P < 0.05) the activities of glutathione peroxidase, glutathione reductase, and superoxide dismutase in liver and spleen of broilers compared to the control group. Based on the results, it is concluded that oxidative stress in broiler chicken reared in tropical summer could be reduced by supplementing sprouted pulses without affecting performance, carcass variables, and immune responses. PMID- 29470741 TI - Electrospun eri silk fibroin scaffold coated with hydroxyapatite for bone tissue engineering applications. AB - Natural biomaterials such as collagen, silk fibroin, and chitosan, and synthetic biopolymers such as polylactic acid, polycaprolactone, polyglycolic acid, and their copolymers are being used as scaffold for tissue engineering applications. In the present work, a fibrous mat was electrospun from eri silk fibroin (ESF). A composite of hydroxyapatite (Hap) and the ESF scaffold was prepared by soaking the ESF scaffold in a solution of calcium chloride and then in sodium diammonium phosphate. The average tensile stress of the pure ESF and hydroxyapatite-coated ESF scaffold (ESF-Hap) was found to be 1.84 and 0.378 MPa, respectively. Pure ESF and ESF-Hap scaffolds were evaluated for their characteristics by a themogravimetric analyzer and Fourier transform infrared spectroscope. The crystallinity and thermal stability of the ESF-Hap scaffold were found to be more than that of uncoated eri silk nanofiber scaffold. The water uptake of the pure ESF and ESF-Hap scaffolds was found to be 69% and 340%, respectively, in distilled water as well as phosphate buffer saline. The hemolysis percentage of both scaffolds was less than 5%, which indicate their good blood compatibility. The cytocompatibility studied by 3-(4,5-dimethyl) thiazol-2-yl-2,5-dimethyl tetrazolium bromide assay showed that the scaffold is biocompatible. To assess cell attachment and growth on the scaffold, human mesenchymal stem cells were cultured on the scaffolds. The results from scanning electron microscopy and fluorescent microscopy showed a notable cellular growth and favorable morphological features. Hence, the ESF-Hap scaffold is better suited for cell growth than the pure ESF scaffold. PMID- 29470742 TI - Renal hemosiderosis with uncontrolled hypertension. PMID- 29470744 TI - Polystyrene microsphere and 5-fluorouracil release from custom-designed wound dressing films. AB - Custom-designed wound dressing films of chitosan and alginate have been prepared by a casting/solvent evaporation method for hydrophobic therapeutic agent encapsulation. In this parametric study, the propylene glycol (PG) and calcium chloride (CaCl2) concentrations were varied for chitosan and alginate films, respectively. Mechanical and chemical inter-related responses under observations included thickness (th), elasticity (E), tensile strength (TS), sorption ability (S%) and kinetics of in-vitro drug release, specifically in terms of membrane time to burst (t B ) and duration of release (t R ). As shown by results of a one tailed t-test significance testing at the 95% confidence interval (alpha = 0.05), alginate films were significantly more elastic (p = 0.003), thinner (p = 0.004) and more susceptible to osmotic burst (p = 0.011) and characterized by a longer duration of release (p = 0.03). Meanwhile chitosan films exhibited superior moisture permeability (p = 0.006) and sorption characteristics (p = 0.001), indicative of higher hydrophilicity. There were no significant differences in tensile strength (p = 0.324) for alginate and chitosan-based formulations. Preliminary testing was conducted using 0.71 MUm in diameter microspheres for modeling film dissolution into Lactated Ringer's solution. Experimental release profiles were modeled for each film from which the average release from alginate films (M AGCa = 81%) was estimated to be twice the percentage associated with chitosan films (M CD = 42%). The film comprised of 2.5% (w/v) medium MW chitosan/dextran 70 kDa (5:1) was selected for studying the release of 5 Fluorouracil (5-FU) as a model hydrophobic drug. Diffusion coupled with film disintegration is immediate (t B = 0) in case of encapsulated 5-FU as compared to the control film encapsulating microspheres characterized by t B = 70 min +/- 7 min. This shift in release profile and the ability to modulate the timing of membrane burst can be attributed to the approximate ratio (1: 505) in molecular size between drug and microsphere. This hypothesis has been validated by the film pore size measured to be 430 nm +/- 88 nm using atomic force microscopy. PMID- 29470743 TI - Progress and challenges in biomaterials used for bone tissue engineering: bioactive glasses and elastomeric composites. AB - Driven by the increasing economic burden associated with bone injury and disease, biomaterial development for bone repair represents the most active research area in the field of tissue engineering. This article provides an update on recent advances in the development of bioactive biomaterials for bone regeneration. Special attention is paid to the recent developments of sintered Na-containing bioactive glasses, borate-based bioactive glasses, those doped with trace elements (such as Cu, Zn, and Sr), and novel elastomeric composites. Although bioactive glasses are not new to bone tissue engineering, their tunable mechanical properties, biodegradation rates, and ability to support bone and vascular tissue regeneration, as well as osteoblast differentiation from stem and progenitor cells, are superior to other bioceramics. Recent progresses on the development of borate bioactive glasses and trace element-doped bioactive glasses expand the repertoire of bioactive glasses. Although boride and other trace elements have beneficial effects on bone remodeling and/or associated angiogenesis, the risk of toxicity at high levels must be highly regarded in the design of new composition of bioactive biomaterials so that the release of these elements must be satisfactorily lower than their biologically safe levels. Elastomeric composites are superior to the more commonly used thermoplastic matrix composites, owing to the well-defined elastic properties of elastomers which are ideal for the replacement of collagen, a key elastic protein within the bone tissue. Artificial bone matrix made from elastomeric composites can, therefore, offer both sound mechanical integrity and flexibility in the dynamic environment of injured bone. PMID- 29470745 TI - Estimated Brain Tissue Response Following Impacts Associated With and Without Diagnosed Concussion. AB - Kinematic measurements of head impacts are sensitive to sports concussion, but not highly specific. One potential reason is these measures reflect input conditions only and may have varying degrees of correlation to regional brain tissue deformation. In this study, previously reported head impact data recorded in the field from high school and collegiate football players were analyzed using two finite element head models (FEHM). Forty-five impacts associated with immediately diagnosed concussion were simulated along with 532 control impacts without identified concussion obtained from the same players. For each simulation, intracranial response measures (max principal strain, strain rate, von Mises stress, and pressure) were obtained for the whole brain and within four regions of interest (ROI; cerebrum, cerebellum, brain stem, corpus callosum). All response measures were sensitive to diagnosed concussion; however, large inter athlete variability was observed and sensitivity strength depended on measure, ROI, and FEHM. Interestingly, peak linear acceleration was more sensitive to diagnosed concussion than all intracranial response measures except pressure. These findings suggest FEHM may provide unique and potentially important information on brain injury mechanisms, but estimations of concussion risk based on individual intracranial response measures evaluated in this study did not improve upon those derived from input kinematics alone. PMID- 29470746 TI - Nitinol Stents in the Femoropopliteal Artery: A Mechanical Perspective on Material, Design, and Performance. AB - Endovascular stenting has matured into a commonly used treatment for peripheral arterial disease (PAD) due to its minimally invasive nature and associated reductions in short-term morbidity and mortality. The mechanical properties of the superelastic Nitinol alloy have played a major role in the explosion of peripheral artery stenting, with modern stents demonstrating reasonable resilience and durability. Yet in the superficial femoral and popliteal arteries, even the newest generation Nitinol stents continue to demonstrate clinical outcomes that leave significant room for improvement. Restenosis and progression of native arterial disease often lead to recurrence of symptoms and reinterventions that increase morbidity and health care expenditures. One of the main factors thought to be associated with stent failure in the femoropopliteal artery (FPA) is the unique and highly dynamic mechanical environment of the lower limb. Clinical and experimental data demonstrate that the FPA undergoes significant deformations with limb flexion. It is hypothesized that the inability of many existing stent designs to conform to these deformations likely plays a role in reconstruction failure, as repetitive movements of the leg and thigh combine with mechanical mismatch between the artery and the stent and result in mechanical damage to both the artery and the stent. In this review we will identify challenges and provide a mechanical perspective of FPA stenting, and then discuss current research directions with promise to provide a better understanding of Nitinol, specific features of stent design, and improved characterization of the biomechanical environment of the FPA to facilitate development of better stents for patients with PAD. PMID- 29470747 TI - Solid Stress Facilitates Fibroblasts Activation to Promote Pancreatic Cancer Cell Migration. AB - Pancreatic fibroblasts are continuously gaining ground as an important component of tumor microenvironment that dynamically interact with cancer cells to promote tumor progression. In addition, these tumor-infiltrated fibroblasts can acquire an activated phenotype and produce excessive amounts of extracellular matrix creating a highly dense stroma, a situation known as desmoplasia. Desmoplasia, along with the uncontrolled proliferation of cancer cells, leads to the development of compressive forces within the tumor, generating the so-called solid stress. Solid stress is previously shown to affect cancer cell proliferation and migration, however there is no pertinent study taking into account the effects of solid stress on fibroblasts and whether these effects contribute to tumor progression. In this work, we applied a defined compressive stress on pancreatic fibroblasts, similar in magnitude to that experienced by cells in native pancreatic tumors. Our results suggest that solid stress stimulates fibroblasts activation and strongly upregulates Growth Differentiation Factor-15 (GDF15) expression. Moreover, co-culture of compression-induced activated fibroblasts with pancreatic cancer cells significantly promotes cancer cell migration, which is inhibited by shRNA-mediated silencing of GDF15 in fibroblasts. Conclusively, our findings highlight the involvement of biophysical factors, such as solid stress, in tumor progression and malignancy revealing a novel role for GDF15. PMID- 29470748 TI - Investigating the Longitudinal Effect of Ovariectomy on Bone Properties Using a Novel Spatiotemporal Approach. AB - Osteoporosis is the most common bone disease. However, the mechanism of osteoporosis-induced alterations in bone is still unclear. The aim of this study was to investigate the effects of osteoporosis on the structural, densitometric and mechanical properties of the whole tibia using in vivo MUCT imaging, spatiotemporal analysis and finite element modeling. Twelve C57Bl/6 female mice were adopted. At 14 weeks of age, half of the mice were ovariectomized (OVX), and the other half were SHAM-operated. The whole right tibia was scanned using an in vivo MUCT imaging system at 14, 16, 17, 18, 19, 20, 21 and 22 weeks. The image datasets were registered in order to precisely quantify the bone properties. The results showed that OVX led to a significant increase in the endosteal area across the whole tibia 4 weeks after OVX intervention but did not have a significant influence on the periosteal area. Additionally, the bone volume and mineral content significantly decreased only in the proximal regions, but these decreases did not have a significant influence on the stiffness and failure load of the tibia. This study demonstrated the application of a novel spatiotemporal approach in the comprehensive analysis of bone adaptations in the spatiotemporal space.

PMID- 29470752 TI - Assessing changes in the toxicity of effluents from intensive marine fish farms over time by using a battery of bioassays. AB - Although intensive marine fish farming is often assumed to be eco-friendly, the associated activity can lead to chronic exposure of marine organisms to potentially toxic discharges. Moreover, despite the increasing popularity of integrated multi-trophic aquaculture (IMTA), studies of the effects of fish farm effluents are almost non-existent. In the present study, the changes in the toxic potential of effluents from five land-based marine fish farms in NW Spain subjected for different lengths of time to a biodegradation procedure (for 0, 48, 120, and 240 h) were assessed in a battery of bioassays including organisms from different trophic levels (Vibrio fischeri, Isochrysis galbana, and Paracentrotus lividus). The results of the bioassays at the different times were then considered together with farm water flow in the Potential Ecotoxic Effects Probe (PEEP) index. Despite the high volumes of effluents discharged, the generally low toxicity of the effluents hinders assessment of potentially toxic effects. However, dose-response curves and statistical analysis demonstrated the existence of toxic effects during the first five days of the biodegradation procedure, especially immediately after sampling. The proposed modification of the PEEP index better reflects the changes in toxicity over time. Graphical abstract ?. PMID- 29470751 TI - Method development for determination of migrated phthalate acid esters from polyethylene terephthalate (PET) packaging into traditional Iranian drinking beverage (Doogh) samples: a novel approach of MSPE-GC/MS technique. AB - In the current study, a novel magnetic solid phase extraction (MSPE) technique combined with a gas chromatography/mass spectroscopy (GC/MS) was developed to determine the phthalate ester content of bottled Doogh samples. Doogh is a yogurt based drinking beverage, which is frequently consumed in Middle East and Balkans. It is produced by stirring yogurt in Chern separation machine and consists of substances such as water, yogurt, and salt in addition to aqueous extracts of native herbs. The magnetic multi-walled carbon nanotubes (MWCNT-Fe3O4) were used as adsorbents of phthalate acid esters (PAEs) due to a superior adsorption capability of hydrophobic compounds. In this context, the quantity of the extractable migrated phthalate esters (dibutyl phthalate (DBP), dimethyl phthalate (DMP), butyl benzyl phthalate (BBP), diethyl phthalate (DEP), di-N octyl phthalate (DNOP), and bis (2-ethylhexyl) phthalate (DEHP)) from polyethylene terephthalate (PET) bottles into Doogh samples was measured. The correlation between the concentration of migrated PAEs and some factors such as the type of Doogh (gaseous and without gas), difference in brand (five brands), volume (1500 and 300 mL), and the storage time also was investigated. The migration level into Doogh samples was increased by incorporating of gas as well as increasing the volume of PET bottles. Also, with elaborating of storage time, the migration of some phthalates such as DEHP (the mean from 2419.85 ng L-1 in the first week to 2716.15 ng L-1 in the second month), DEP, and total phthalate was increased. However, no significant difference in concentrations of migrated phthalate esters among different examined brands was noted. Finally, the concentration of migrated PAEs from bottle into all the examined Doogh samples was below the defined standards by EPA; 6 MUg/L for DEHP in drinking water. Graphical abstract ?.

AB - The Indus River Basin (IRB) with an area of 139,202 km2 is the lifeline river basin of Pakistan. An intensive study was conducted in six subcatchments of the IRB with five in the Upper Indus Basin (UIB) and one of the Lower Indus Basin (LIB; between Tarbela Dam and Panjand), i.e., the Gilgit River Basin (UIB-I), Hunza River Basin (UIB-II), UIB-III, UIB-IV and UIB-V, and LIB. A total of 84 surface water samples were collected from main stream and tributaries from June to August, 2016. The pH, electric conductivity (EC), and total dissolved solids (TDS) were measured in situ, whereas major ions (Ca2+, Mg2+, K+, Na+, Cl-, SO42-, and NO3-) and Si were analyzed in the laboratory. The results exhibited alkaline pH (8.55 +/- 0.20) with diverse TDS (114.69 +/- 77.65 mg L-1) and ion concentrations that were characterized primarily by the Ca-Mg-HCO3 type in the whole basin. The average TDS in the UIB and LIB were 93.99 +/- 39.73 and 181.67 +/- 167.82 mg L-1, respectively, under the influence of the arid to semi-arid climatic conditions and relatively higher anthropogenic interference in LIB compared to the UIB. The order of dominant major cations was different in the UIB and LIB, reflecting the diverse nature of geological formation. Gibbs plot, mixing diagrams, and ionic ratios were used to identify the controlling mechanism of river geochemistry in the IRB as carbonate weathering in general with different degrees of silicate weathering and minor contribution by evaporite dissolution. In addition, principal component/factor analysis also indicated that the major sources of dissolved loads in the basin are carbonates followed by silicates. Significant influences of silicate minerals were observed in the LIB, and there was a large contribution of evaporites in the UIB-II, UIB-III, and LIB. The suitability assessment showed that the river water fits the WHO permissible limits for drinking purposes from the perspective of major ions, whereas for irrigation purposes, most of the samples exhibited excellent and good levels except for a couple of permissible and doubtful levels from the Sawan and Deratang tributaries in the LIB, which may deteriorate the quality of soil and degrade the water quality downstream. PMID- 29470755 TI - Water planning in a mixed land use Mediterranean area: point-source abstraction and pollution scenarios by a numerical model of varying stream-aquifer regime. AB - Integrated hydrodynamic modelling is an efficient approach for making semi quantitative scenarios reliable enough for groundwater management, provided that the numerical simulations are from a validated model. The model set-up, however, involves many inputs due to the complexity of both the hydrological system and the land use. The case study of a Mediterranean alluvial unconfined aquifer in the lower Var valley (Southern France) is useful to test a method to estimate lacking data on water abstraction by small farms in urban context. With this estimation of the undocumented pumping volumes, and after calibration of the exchange parameters of the stream-aquifer system with the help of a river model, the groundwater flow model shows a high goodness of fit with the measured potentiometric levels. The consistency between simulated results and real behaviour of the system, with regard to the observed effects of lowering weirs and previously published hydrochemistry data, confirms reliability of the groundwater flow model. On the other hand, accuracy of the transport model output may be influenced by many parameters, many of which are not derived from field measurements. In this case study, for which river-aquifer feeding is the main control, the partition coefficient between direct recharge and runoff does not show a significant effect on the transport model output, and therefore, uncertainty of the hydrological terms such as evapotranspiration and runoff is not a first-rank issue to the pollution propagation. The simulation of pollution scenarios with the model returns expected pessimistic outputs, with regard to hazard management. The model is now ready to be used in a decision support system by the local water supply managers. PMID- 29470754 TI - Mitigation measures to avert the impacts of plastics and microplastics in the marine environment (a review). AB - The increasing demand for and reliance on plastics as an everyday item, and rapid rise in their production and subsequent indiscriminate disposal, rise in human population and industrial growth, have made the material an important environmental concern and focus of interest of many research. Historically, plastic production has increased tremendously to over 250 million tonnes by 2009 with an annual increased rate of 9%. In 2015, the global consumption of plastic materials was reported to be > 300 million tonnes and is expected to surge exponentially. Because plastic polymers are ubiquitous, highly resistant to degradation, the influx of these persistent, complex materials is a risk to human and environmental health. Because microplastics are principally generated from the weathering or breakdown of larger plastics (macroplastics), it is noteworthy and expedient to discuss in detail, expatiate, and tackle this main source. Macro and microplastic pollution has been reported on a global scale from the poles to the equator. The major problem of concern is that they strangulate and are ingested by a number of aquatic biota especially the filter feeders, such as molluscs, mussels, oysters, from where it enters the food chain and consequently could lead to physical and toxicological effects on aquatic organisms and human being as final consumers. To this end, in order to minimise the negative impacts posed by plastic pollution (macro- and microplastics), a plethora of strategies have been developed at various levels to reduce and manage the plastic wastes. The objective of this paper is to review some published literature on management measures of plastic wastes to curb occurrence and incidents of large- and microplastics pollution in the marine environments. PMID- 29470756 TI - Study on transport and transformation of contaminant through layered soil with large deformation. AB - Based on large-deformation consolidation theory and the advection-dispersion equation of contaminant in saturated porous media, a one-dimensional theoretical model for coupled large-deformation and solute transport through layered finite soil is presented. This model comprehensively takes the effect of soil weight, sorption, and biodegradation into account. Model validation and applications are achieved through case studies of double-layered finite soil, with the transport and transformation process of contaminant being reproduced numerically. It is found that the breakthrough time of contaminant obtained from the linear adsorption solution is greater than the case of the non-linear adsorption solution, which can provide a reference for the design of landfill liner. Simulation results also indicate that relevant factors affect the transport of contaminant in layered soil interdependently; comprehensive study is required to assess the capacity of natural clay barrier for contaminant transportation.

AB - Research examining factors that predict youth's involvement in organized activities is very limited, despite associations with positive outcomes. Using data from 1043 youth (49% female; 46.4% Hispanic, 35.4% African American, 14.0% Caucasian, and 4.2% other) from the Project on Human Development in Chicago Neighborhoods, this study examined how characteristics of parents (supervision, warmth) and neighborhoods (perceived neighborhood safety and collective efficacy) predict patterns of adolescents' involvement in organized activities concurrently (i.e., intensity) and longitudinally (i.e., type and breadth). Parental supervision predicted adolescents' participation in organized activities across multiple waves. Neighborhood violence was positively associated with concurrent participation in organized activities after controlling for socioeconomic status (SES), whereas higher neighborhood collective efficacy predicted greater breadth in organized activity participation across time. These findings have important implications regarding how to attract and sustain organized activity participation for low-income, urban youth. PMID- 29470759 TI - Problem Gambling and Delinquent Behaviours Among Adolescents: A Scoping Review. AB - Despite many studies indicating an association between problem gambling and delinquent behaviours among adolescents, there has been no effort to systematically analyze the state of the literature on this relationship. To fill this gap, we conducted a scoping review of the literature published between 2000 and 2016 on problem gambling and delinquent behaviours among adolescents. We searched twelve databases and reviewed reference lists to identify eligible studies. Search terms included a combination of medical subject headings and keywords for gambling, youth, and delinquency, which were combined with the Boolean operator "AND". 1795 studies were identified through the literature search. Nine studies were eligible for inclusion. All of the studies were conducted in North America, with primarily male participants, and most of the data were cross-sectional. No qualitative studies met the inclusion criteria. Screening tools used to measure problem gambling were inconsistent, making comparisons across studies difficult. We found a consistent moderate to strong association between problem gambling and delinquent behaviour. Only one study presented associations by socio-economic status and none considered gender, sex or ethnic differences. Studies in the review showed that problem gambling is associated with both violent and non-violent behaviours among adolescents. These associations may suggest that problem gambling and delinquent behaviours have common risk factors and reflect a syndrome of risky behaviours best targeted through prevention and treatment that is holistic and considers the context in which the youth is situated. Further research is warranted to better understand the relationship between problem gambling and delinquent behaviours. PMID- 29470761 TI - The Rise and Fall of Depressive Symptoms and Academic Stress in Two Samples of University Students. AB - Self-reported depressive experiences are common among university students. However, most studies assessing depression in university students are cross sectional, limiting our understanding of when in the academic year risk for depression is greatest and when interventions may be most needed. We examined within-person change in depressive symptoms from September to April. Study 1 (N = 198; 57% female; 72% white; Mage = 18.4): Depressive symptoms rose from September, peaked in December, and fell across the second semester. The rise in depressive symptoms was associated with higher perceived stress in December. Study 2 (N = 267; 78.7% female; 67.87% white; Mage = 21.25): Depressive symptoms peaked in December and covaried within persons with perceived stress and academic demands. The results have implications for understanding when and for whom there is increased risk for depressive experiences among university students.

AB - Parents' educational aspirations for youth play an important role in shaping youth's own educational aspirations; however, little is known about how and in what context parents may transmit their aspirations to youth effectively. This is of particular interest and import to be examined in Chinese families, given Chinese cultural emphasis on educational achievement and Chinese youth's outstanding academic performance internationally. By integrating several key theories of motivation and parental socialization (i.e., the expectancy-value model of academic achievement, the two-step model of value transmission, the contextual model of parenting, and the self-determination theory), the current study investigated simultaneously the mediating roles of parental involvement in youth's learning and youth's perceptions of parental aspirations, as well as the moderating role of parental warmth in the intergenerational transmission process of educational aspirations in Chinese families. A two-wave longitudinal study spanning about half a year was conducted among 323 Chinese seventh graders (54% female; Mage = 13.25 years) and one of their parents (median educational attainment = completion of high school, median monthly income = USD 766-1226). It was found that parental educational aspirations for youth were related positively both indirectly through parental involvement and directly to youth's perceptions of parental aspirations, which in turn were associated positively with youth's own educational aspirations about half a year later. It was also found that parental educational aspirations for youth and youth's own educational aspirations were associated positively with each other only when youth reported experiencing high levels of parental warmth, but unrelated when youth reported experiencing low levels of parental warmth, whereas such moderating effects of parental warmth were absent on the links from parental aspirations to youth's perceptions of parental aspirations and parental involvement. These findings highlight the importance of integrating multiple theories to understand parent-to youth transmission of educational aspirations in non-western cultures, which helps not only reveal generalizability, as well as boundary conditions for Western-originated theories, but also inform practical endeavors at promoting youth's educational achievement worldwide to draw on strengths of different cultures. PMID- 29470763 TI - A Rapid On-Site Assay for the Detection of Influenza A by Capillary Convective PCR. AB - BACKGROUND: Morbidity and mortality from influenza A (Flu A) have increased in recent years. Timely diagnosis and management are critical for disease control. Therefore, the development of a rapid, accurate, and portable analytical method for on-site analysis is imperative. OBJECTIVES: The aim of this work was to develop a rapid, on-site, automated assay for the detection of Flu A and to evaluate the assay. METHODS: A handheld instrument (TD-01) based on capillary convective polymerase chain reaction (PCR) was developed for rapid on-site detection of Flu A. Since a previous version of the instrument, an automated motion mechanism has been introduced to TD-01 to achieve RNA automated testing. The primers and probe used for Flu A detection were designed according to the Flu A gene sequence of matrix proteins. Finally, we evaluated the detection spectra, sensitivity, specificity, and diagnostic performance of the assay. RESULTS: The TD-01 was able to successfully automatically detect Flu A RNA within 30 min. Results for serially diluted viruses indicated that the lower limit of detection for Flu A was 0.1 TCID50/ml (50% tissue culture infective dose). After evaluating known virus stocks, including 15 strains of Flu A, four strains of Flu B, and two strains of respiratory syncytial virus (RSV), the assay had a favorable detection spectrum and no obvious cross-reactivity. Method verification based on 554 clinical samples indicated that the sensitivity and specificity of TD-01 were 98.30% (231/235) and 98.75% (315/319), respectively. CONCLUSIONS: The results indicate that Flu A detection by TD-01 is particularly suitable for on-site testing and has the potential for application in point-of-care testing. PMID- 29470764 TI - Levels of Circulating mRNA for the Tenascin-X (TNXB) Gene in Maternal Plasma at the Second Trimester in Pregnancies with Isolated Congenital Ventricular Septal Defects. AB - OBJECTIVE: Maternal plasma is a source of circulating placental nucleic acids. In this study, we validated previous observations on abnormal levels of circulating messenger RNA (mRNA) for the tenascin-X gene in pregnancies with ventricular septal defects in the second trimester of pregnancy. METHODS: This was a bicentric retrospective study conducted from March 2016 to July 2017. Real-time polymerase chain reaction was used to identify abnormally expressed genes, comparing ten women carrying a euploid fetus with ventricular septal defects to 30 controls at 19-24 weeks of gestation. The univariable analysis was used to determine whether the mean mRNA for the tenascin-X gene values would differ from the expected values for the controls. RESULTS: mRNA for tenascin-X gene values was higher in ventricular septal defects, 4.38 +/- 3.01 versus 1.00 +/- 0.80. The result was still significant even after adjustment for gestational age. CONCLUSIONS: These data confirm previous studies on the specific association of mRNA species and type of congenital heart defect and confirm that ventricular septal defects are associated with abnormal mRNA for the tenascin-X gene. The positive predictive value of this molecular marker in the general population should be assessed through prospective studies. PMID- 29470765 TI - Angiotensin II receptor blockers for the treatment of portal hypertension in patients with liver cirrhosis: a systematic review and meta-analysis of randomized controlled trials. AB - BACKGROUND: Randomized controlled trials (RCTs) showed inconsistent results regarding the efficacy of angiotensin II receptor blockers (ARBs) on portal pressure as indicated by hepatic venous pressure gradient (HVPG). METHODS: A meta analysis of RCTs was performed to evaluate the influence of ARBs treatment on HVPG. PubMed, Embase, and Cochrane's Library were searched for relevant RCTs. A fixed or a randomized effect model was used to pool the results according the heterogeneity. Subgroup analyses were performed to explore the source of heterogeneity. RESULTS: Eleven RCTs with 394 patients were included. ARBs treatment did not significantly change HVPG as compared with controls (weighted mean difference [WMD] = -0.63, 95% confidence interval [CI] -1.73 to 0.47 mmHg, p = 0.26; I2 = 60%). These results were consistent in studies comparing ARBs with propranolol (WMD = -0.40, 95% CI -2.22 to 1.41 mmHg, p = 0.67; I2 = 68%), and those comparing ARBs with non-active controls including placebo or no treatment (WMD = -1.05, 95% CI -2.33 to 0.24 mmHg, p = 0.13; I2 = 44%). These results were also not affected by the individual ARBs used. Moreover, treatment of ARBs significantly reduced mean arterial blood pressure (WMD = -6.12, 95% CI -9.69 to 2.55 mmHg, p = 0.008; I2 = 53%), and the risk of symptomatic hypotension was increased (RR = 4.13, 95% CI 0.94 to 18.18, p = 0.06; I2 = 0%). CONCLUSIONS: ARBs did not reduce portal pressure in patients with cirrhosis; moreover, the risk of symptomatic hypotension may increase. PMID- 29470766 TI - Haloperidol attenuates Methylphenidate and Modafinil induced behavioural sensitization and cognitive enhancement. AB - Previous studies have demonstrated that repeated psychostimulant administration produces behavioural sensitization and cognitive tolerance. Brain dopaminergic system and the involvement of dopamine D2-receptors are considered to be important in psychostimulant-induced sensitization. Study designed to compared the motor activity by using familiar and novel enviroments and cognitive effects by water maze and passive avoidance test after long term administration of methylphenidate(at the dose 0.6 mg/kg/day, 2.5 mg/kg/day and 10 mg/kg/day) and modafinil (50 mg/kg/day, 64 mg/kg/day and 75 mg/kg/day) in rats. The effects of challenge dose of haloperidol (at the dose of 1 mg/kg i.p.) has monitored to visualize any subsensitization or supersensitization of D2 receptors. We found that motor activity and cognitive performance was increased in all doses and sensitization effect was more pronounced after 13 days of drug administration were greater at high than low and medium doses.Challenge dose of haloperidol attenuate motor activity in familiar and novel environment and impaired cognition in water maze and passive avoidance test in all treated rats. The effect of Haloperidol in high dose treated rats were however somewhat greater than low and medium dose treated rats following methylphenidate and modafinil administration. Increased response of haloperidol in methylphenidate treated rats can be explained in term of supersensitization of D2 receptors which is greater in high dose treated rats. The results show that the role of D2 receptors to develop side effects such as behavioural sensitization and cognitive tolerance by the long term administration of psychostimulants is of sufficient importance and helpful in understanding the mechanisms underlying the undesirable effects of psychostimulants. PMID- 29470767 TI - The effects of tramadol administration on hippocampal cell apoptosis, learning and memory in adult rats and neuroprotective effects of crocin. AB - Tramadol, a frequently used pain reliever drug, present neurotoxic effects associated to cognitive dysfunction. Moreover, crocin has been reported to have neuroprotective effects. The aim of this study was to assess crocin's capacity to protect learning, and memory abilities on tramadol-treated rats. A total of 35 rats were divided into five groups: Control, Saline, tramadol (50 mg/kg), tramadol + crocin(30 mg/kg), crocin groups and treated orally for 28 consecutive days. Morris water maze (MWM) and passive avoidance (PA) tests were done, followed by dissection of the rat's brains for toluidine blue and TUNEL staining. In MWM test, tramadol group spent lower time and traveled shorter distance in the target quadrant (Q1) (P < 0.05). On the other side, the traveled distance in tramadol-crocin group was higher than tramadol (P < 0.05). In PA test, both the delay for entering the dark, and the total time spent in the light compartment decreased in tramadol comparing to the control group (P < 0.05), while it increased in tramadol-crocin compared with the tramadol group (P < 0.05). In tramadol-treated animals, the dark neurons (DNs) and apoptotic cells in CA1, CA3 and DG increased (P < 0.05), while concurrent intake of crocin decreased the number of DNs and apoptotic cells in these areas (P < 0.05). Crocin was able to improve learning and memory of tramadol-treated rats and also decreased DNs and apoptotic cells in the hippocampus. Considering these results, the potential capacity of crocin for decreasing side effects of tramadol on the nervous system is suggested. PMID- 29470768 TI - Invivo biocompatibility determination of acellular aortic matrix of buffalo origin. AB - In the present study, biocompatibility of native, acellular, 1,4-butanediol diglycidylether and 1-ethyl-3-(3-dimethyl aminopropyl carbodiimide (EDC) cross linked acellular aortic grafts was evaluated following subcutaneous implantation in guinea pigs. Biocompatibility was evaluated based on macroscopic, histopathological observations and immune responses elicited by the implanted grafts. Results showed that macroscopically, no abnormal cellular reaction was observed at the host-graft junction in any of the implanted animals. Histopathological observations revealed that the inflammatory response was mild during first 15 days post-implantation and increased at 30 days post-implantation in acellular and cross-linked tissues. By day 60, marked ingrowth of host tissue was observed in EDC cross-linked acellular aortic grafts. ELISA and lymphocyte proliferation assay revealed that animals implanted with EDC grafts showed least immune response when compared to others. Therefore, it was concluded that EDC cross-linked acellular aortic grafts were more compatible and had better handling qualities than the other cross-linked grafts. PMID- 29470769 TI - Advancement of wound care from grafts to bioengineered smart skin substitutes. AB - This review gives a brief description on the skin and its essential functions, damages or injury which are common to the skin and the role of skin substitute to replace the functions of the skin soon after an injury. Skin substitutes have crucial role in the management of deep dermal and full thickness wounds. At present, there is no skin substitute in the market that can replace all the functions of skin 'and the research is still continuing for a better alternative. This review is an attempt to recollect and report the past efforts including skin grafting and recent trends like use of bioengineered smart skin substitutes in wound care. Incorporation functional moieties like antimicrobials and wound healing agents are also described. PMID- 29470770 TI - Antibacterial effects of silver-zirconia composite coatings using pulsed laser deposition onto 316L SS for bio implants. AB - Bacterial invasion on biomedical implants is a challenging task for long-term and permanent implant fixations. Prevention of initial bacterial adherence on metallic implants is an important concern to avoid extracellular matrix (biofilm) secretion from bacteria that is resistant to antibacterial agents. In order to overcome this defect, recently, surface coatings such as zirconia (ZrO2) with higher smoothness have been shown to improve implants durability. In the present study, pulsed laser deposition (PLD) was used to deposit ZrO2 and silver (Ag) ZrO2 composite coatings onto 316L stainless steel (316L SS). Phase purity, surface roughness and surface morphology, thickness of the coatings and elemental compositions of the coatings were analyzed using X-ray diffraction (XRD), atomic force microscopy (AFM) and scanning electron microscopy (SEM) with energy dispersive X-ray spectroscopy (EDS). Total viable count (TVC) and epifluorescence microscopy analysis were studied to evaluate antimicrobial efficiency of ZrO2 and Ag-ZrO2 composite coatings using gram negative (gram -ve) Escherichia coli (E.coli) and gram positive (gram +ve) Staphylococcus aureus (S.aureus). On the basis of the present study, it could be speculated that ZrO2 coatings exhibited antibacterial activity against only E.coli, whereas Ag-ZrO2 composite coatings showed superior activity against E.coli and S.aureus strains. PMID- 29470771 TI - In vitro-in vivo correlation from lactide-co-glycolide polymeric dosage forms. AB - The objective of this study was to compare the in vitro behavior of four long acting subcutaneous risperidone formulations with in vivo performance, with the intent of establishing an IVIVC. Two copolymers of PLGA (50:50 and 75:25) were used to prepare four microsphere formulations of risperidone, an atypical antipsychotic. In vitro behavior was assessed at the physiological temperature (37 degrees C) using the 'modified dialysis' technique. The in vitro release profile demonstrated rank order behavior with Formulations A and B, prepared using the 50:50 copolymer, exhibiting rapid drug release, while Formulations C and D, prepared using 75:25 PLGA, released drug in a slower manner. In vivo profiles were obtained by two approaches, i.e., deconvolution using the Nelson Wagner equation (the FDA recommended approach) and using fractional AUC. With both in vivo approaches, the 50:50 PLGA preparations released drug faster than the 75:25 PLGA microspheres, exhibiting the same rank order observed in vitro. Additionally, profiles for the four formulations obtained using the deconvolution approach were nearly superimposable with fractional AUC, implying that the latter procedure could be used as a substitute for the Nelson-Wagner method. A comparison of drug release profiles for the four formulations revealed that in three of the four formulations, in vivo release was slightly faster than that in vitro, but the results were not statistically significant (P > 0.0001). An excellent linear correlation (R2 values between 0.97 and 0.99) was obtained when % in vitro release for each formulation was compared with its corresponding in vivo release profile, obtained by using fraction absorbed (Nelson-Wagner method) or fractional AUC. In summary, using the four formulations that exhibited different release rates, a Level A IVIVC was established using the FDA recommended deconvolution method and fractional AUC approach. The excellent relationship between in vitro drug release and the amount of drug absorbed in vivo in this study was corroborated by the nearly 1:1 correlation (R2 greater than 0.97) between in vitro release and in vivo performance. Thus, the results of the current study suggest that proper selection of an in vitro method to assess drug release from long-acting injectables will aid in obtaining a Level A IVIVC. PMID- 29470772 TI - Robotics confers an advantage in right hemicolectomy with intracorporeal anastomosis when matched against conventional laparoscopy. AB - Comparisons between robotic and laparoscopic right hemicolectomy have been confounded by variations in operative technique. This study evaluates the two procedures after standardizing the intraoperative steps and perioperative management. Patients who underwent robotic right hemicolectomy with intracorporeal bowel anastomosis between July 2015 and June 2017 were matched with a laparoscopic group. Perioperative management was in accordance to an enhanced recovery protocol. Outcomes and histopathological data were compared. Thirty-two patients were included. Amongst the patients who did not undergo complete mesocolic excision, the median operative time did not differ between the two groups (p = 0.413). The robotic group recorded a statistically shorter time for intracorporeal anastomosis (13 vs 19 min, p = 0.024). Postoperative recovery and complication rates were similar, except for a greater lymph node harvest in the robotic group (41 vs 31, p = 0.038). Robotic surgery achieves short-term results comparable to existing conventional laparoscopy, notwithstanding the advantages of enhanced ergonomics. PMID- 29470773 TI - Estimation of linear energy transfer distribution for broad-beam carbon-ion radiotherapy at the National Institute of Radiological Sciences, Japan. AB - A treatment of carbon-ion radiotherapy (CIRT) is generally evaluated using the dose weighted by relative biological effectiveness (RBE) while ignoring the radiation quality varying in the patient. In this study, we have developed a method of estimating linear energy transfer (LET) from the RBE in an archived treatment plan to represent the radiation quality of the treatment. The LET in a beam database was associated with the RBE by two fitting functions per energy, one for the spread-out Bragg peak (SOBP) and the other for shallower depths, to be differentiated by RBE per energy per modulation. The estimated LET was generally consistent with the original calculation within a few keV/MUm, except for the overkill region near the distal end of SOBP. The knowledge of experimental radiobiology can thereby be associated with CIRT treatments through LET, which will potentially contribute to deeper understanding of clinical radiobiology and further optimization of CIRT. PMID- 29470774 TI - Multi-indication and Combination Pricing and Reimbursement of Pharmaceuticals: Opportunities for Improved Health Care through Faster Uptake of New Innovations. AB - Many pharmaceuticals are effective in multiple indications and the degree of effectiveness may differ. A product-based pricing and reimbursement system with a single price per product is insufficient to reflect the variable values between different indications. The objective of this article is to present examples of actual pricing and reimbursement decisions using current value-based pricing in Sweden and to discuss their implications and possible solutions. The value of several cancer drugs was estimated for various indications based on a willingness to-pay threshold of 1 million SEK (EUR 104,000) per QALY gained. For some drugs, the estimated value was higher than the drug acquisition cost in several indications, whilst in others, the estimated value was lower than the drug acquisition cost. Drugs used in combination present a special case. If a drug prolongs survival and consequently also a continued use of the anchor drug, the combination use may not be cost effective even at a zero price. In a product based pricing and reimbursement system, patients may not get access to drugs or access may be delayed and manufacturers may be discouraged to invest in future indications. To overcome these issues, there are several approaches to link price and value. One approach is a "weighted-average" price based on an average of the value across all indications. Another is "multi-indication pricing," which enables price differentiation between indications. However, there are several barriers for applying multi-indication pricing and reimbursement schemes. One barrier is the lack of existing administrative infrastructure to track patients' indications. PMID- 29470775 TI - Influence of body mass index in anti-Mullerian hormone levels in 951 non polycystic ovarian syndrome women followed at a reproductive medicine unit. AB - PURPOSE: Anti-Mullerian hormone (AMH) is a useful marker of ovarian reserve. Obesity/overweight are increasing and may affect the reproductive health. Previous studies regarding the effect of body mass index (BMI) on AMH levels are discordant. Our main goal was to evaluate the influence of BMI on AMH levels in women without polycystic ovarian syndrome. METHODS: Revision of medical records of 951 women who performed AMH determinations as part of their fertility workup, between 2011 and 2016. RESULTS: Median AMH concentration was 1.75 [interquartile range (IQR) 2] ng/mL (12.9 pmol/mL) and median age at AMH determination was 35 (IQR 6) years. These women evidenced a median BMI of 23 (IQR 5) kg/m2. Caucasian women were more represented [889(89.3%)]. Smoking habits (present/past) were present in 359(36.1%), and 147(14.8%) harboured a history of ovarian surgery. On univariable analysis AMH was not correlated with BMI (r = 0.048/p = 0.135); the only factors influencing AMH were age (p < 0.001), ethnicity (p = 0.004), and previous ovarian surgery (p < 0.001). On multivariable analysis, age was the only variable significantly associated with AMH, evidencing a reduction of 6.2% for each additional year (p < 0.0001). Furthermore, we verified a trend suggesting an AMH reduction of 22% (p = 0.08) in black patients comparing with the caucasian ones, when controlling for the other variables. CONCLUSION: We report one of the largest series evaluating the influence of BMI on AMH levels and, consequently, on ovarian reserve. BMI does not seem to affect AMH levels. The reported concerns on infertility in overweight and obese women may be related to follicular development/oocyte maturation or endometrial disorders, rather than decreased ovarian reserve. PMID- 29470776 TI - A path model analysis on predictors of dropout (at 6 and 12 months) during the weight loss interventions in endocrinology outpatient division. AB - INTRODUCTION: This study aimed to identify the dropout rate at 6 and 12 months from the first outpatient visit, and to analyze dropout risk factors among the following areas: biochemical examinations, anthropometric measures, psychological tests, personal data, and life attitude such as smoking, physical activity, and pathologies. METHODS: This is a retrospective longitudinal observational study. Patients undergo an outpatient endocrinology visit, which includes collecting biographical data, anthropometric measurements, physical and pathological history, psychological tests, and biochemical examinations. RESULTS: The sample consists of 913 subjects (682 women and 231 men), with an average age of 50.88 years (+/-15.80) for the total sample, with a BMI of 33.11 +/- 5.65 kg/m2. 51.9% of the patients abandoned therapy at 6 months after their first visit, and analyzing the dropout rate at 12 months, it appears that 69.5% of subjects abandon therapy. The main predictor of dropout risk factors at 6 and 12 months is the weight loss during the first 3 months (p < 0.05). As regards the hematological predictors, white blood cell and iron level stated dropout at 12 months. Patients who introduced physical activity had a reduction of - 17% (at 6 months) and -13% (at 12 months) of dropout risk (p < 0.05). As regards the "worker" status, patients classified as"retired" had a decrease risk of dropout vs. other categories of worker (i = 0.58; p < 0.05). Dropout risk at 12 months decrease in patients with a previous history of cancer, Endocrine and psychic and behavioral disorders (p < 0.001). CONCLUSIONS: The main factor that predisposes patients to continue therapy or to abandon it is the success (or failure) of the diet in the initial period, based on weight lost (or not lost) in the early months of the initiation of therapy. Furthermore, considerable differences were found in different categories of "workers", and with previous "pathologies". The level of physical activity and previous diseases also seem to be predictors of dropout. PMID- 29470778 TI - Guselkumab for the Treatment of Psoriasis. AB - Psoriasis is a common, chronic, immune-mediated, inflammatory skin disease with systemic involvement and significant impact on patients' quality of life. Several biologic treatments have been developed in recent decades, such as tumor necrosis factor (TNF)-alpha inhibitors, a non-selective interleukin (IL)-23 inhibitor (ustekinumab, which also inhibits IL-12), and-most recently-IL-17 inhibitors. Guselkumab is a novel biological therapy that selectively targets IL-23 and is the first-in-class selective IL-23 inhibitor approved to treat moderate-to-severe plaque psoriasis. These inhibitors are expected to have some advantages over the highly effective IL-17 inhibitors, as they do not worsen inflammatory bowel disease and are not involved in the development of candida infections. Additionally, selective inhibition of IL-23 may have additional benefits over ustekinumab as the IL-12-dependent cascades remain functional. These benefits include a decrease in IL-17A-producing T cells in the skin and the promotion of an anti-inflammatory effect through production of interferon-gamma and IL-10. In terms of efficacy, guselkumab showed promising results in the treatment of psoriasis and psoriatic arthritis, although it did not show significant clinical improvement in rheumatoid arthritis. Studies in other inflammatory diseases and Crohn's disease are expected to begin soon. Overall, guselkumab was well tolerated; the most common adverse event was nasopharyngitis. Head-to-head studies comparing IL-23 inhibitors with agents in different classes, namely IL-17 inhibitors, will be crucial to establish the true role of these agents in psoriasis treatment. PMID- 29470777 TI - Pleiotropic effects of heparins: does anticoagulant treatment increase survival in cancer patients? AB - The association between venous thromboembolism (VTE) and cancer has been recognized for more than 100 years. Numerous studies have been performed to investigate strategies to decrease VTE incidence and to establish whether treating VTE impacts cancer progression and overall survival. Accordingly, it is important to understand the role of the hemostatic system in tumorigenesis and progression, as there is abundant evidence associating it with cell survival and proliferation, tumor angiogenesis, invasion, and dissemination, and metastasis formation. In attempts to further the scientific evidence, several studies examine survival benefits in cancer patients treated with anticoagulant therapy, specifically treatment with vitamin K antagonists, unfractionated heparin, and low-molecular-weight heparin. Several studies and meta-analyses have been conducted with a special focus on brain tumors. However, no definitive conclusions have been obtained, and more well-designed clinical trials are needed.

AB - This article reviews the recent trends, developments, and future applications of bio-based polymers produced from renewable resources. Bio-based polymers are attracting increased attention due to environmental concerns and the realization that global petroleum resources are finite. Bio-based polymers not only replace existing polymers in a number of applications but also provide new combinations of properties for new applications. A range of bio-based polymers are presented in this review, focusing on general methods of production, properties, and commercial applications. The review examines the technological and future challenges discussed in bringing these materials to a wide range of applications, together with potential solutions, as well as discusses the major industry players who are bringing these materials to the market.

AB - A total of 31,425 ticks were collected from 10 cattle and also from six drag samples during the 12-month study period. Adult ticks were removed from the right hand side of each animal and all instars of ticks were placed in containers filled with 70% ethanol. Based on morphological traits, 10 tick species were identified: Rhipicephalus (Boophilus) decoloratus (32.5%), R. evertsi evertsi (18.8%), R. appendiculatus (17.3%), Amblyomma hebraeum (16.3%), R. simus (7.7%), Ixodes pilosus (3.8%), Hyalomma rufipes (3.5%), R. follis (0.08%), Haemaphysalis elliptica (0.04%), H. silacea (0.02%). The southern African yellow dog tick, H. elliptica, was only found on vegetation. The agro-ecological zones differ significantly in tick species and their distribution. The A. hebraeum and R. evertsi evertsi counts were higher in Kowie Thicket (KT) during summer season (2.05 +/- 0.01 and 1.00 +/- 0.09, respectively) compared to Bedford Dry Grassland (BDG) and Bhisho Thornveld (BT) veld types. In all vegetation types, R. appendiculatus had higher counts in KT in spring (0.91 +/- 0.08), summer (0.78 +/ 0.08) and winter (0.78 +/- 0.08). Rhipicephalus (Boophilus) decoloratus was more frequent in the BT (1.78 +/- 0.11) during the summer season. BDG had lower tick infestation with R. evertsi evertsi being the most frequent species in summer. No H. rufipes was collected in the KT. Of epidemiological interest, R. (B.) microplus was absent in the study area which needs further investigation. Within the context of this study, we found agro-ecological differences and seasonal variations to have influence on tick species distribution. PMID- 29470781 TI - Gender-specific differences in cannibalism between a laboratory strain and a field strain of a predatory mite. AB - Many phytoseiid species, including Phytoseiulus persimilis, are known to engage in cannibalism when food is scarce and when there is no possibility to disperse. In nature adult females of P. persimilis are known to disperse when prey is locally depleted. Males, in contrast, are expected to stay and wait for potential mates to mature. During this phase, males can obtain food by cannibalizing. Therefore, we hypothesize that male P. persimilis exhibit a higher tendency to cannibalize than females. Because rearing conditions in the laboratory usually prevent dispersal, prolonged culturing may also affect cannibalistic behavior. We hypothesize that this should especially affect cannibalism by females, because they consume far more food. We tested these hypotheses by comparing males and females from two strains, one of which had been in culture for over 20 years, whereas the other was recently collected from the field. It is known that this predator can discriminate between kin and non-kin and prefers cannibalizing the latter, hence to construct lines with high relatedness we created isofemale lines of these two original strains. We subsequently tested to what extent the adult females and males of the original strains and the isofemale lines cannibalized conspecific larvae from the same strain/line in a closed system. Relatedness with the victims did not affect cannibalistic behavior, but males engaged more often in cannibalism than females, and females of the laboratory strain engaged more in cannibalism than those of the field strain, both in agreement with our ideas. We hypothesize that the difference in cannibalism between the two genders will increase when they have the alternative to disperse.

Many are reminded of the early days of HIV and the rationale for using antiretroviral agents during pregnancy. RECENT FINDINGS: Direct-acting antivirals (DAAs) that are highly potent, all-oral, short-duration regimens that cure HCV have led many to consider what it would entail to use DAAs for pregnant women. Considering HIV and Hepatitis B virus (HBV) as two infections with MTCT to draw lessons from, DAA use to interrupt HCV MTCT comes with risks, costs, and many potential benefits. When considering how to effectively curb the current epidemic of HCV in the US population, using DAAs to treat pregnant women with HCV offers potential benefits to the mother immediately, to the pair in the short-term and to the child, family, and society over a lifetime. PMID- 29470783 TI - The Economic Foundations of Cohabiting Couples' Union Transitions. AB - In recent decades, cohabitation has become an increasingly important relationship context for U.S. adults and their children, a union status characterized by high levels of instability. To understand why some cohabiting couples marry but others separate, researchers have drawn on theories emphasizing the benefits of specialization, the persistence of the male breadwinner norm, low income as a source of stress and conflict, and rising economic standards associated with marriage (the marriage bar). Because of conflicting evidence and data constraints, however, important theoretical questions remain. This study uses survival analysis with prospective monthly data from nationally representative panels of the Survey of Income and Program Participation from 1996-2013 to test alternative theories of how money and work affect whether cohabiting couples marry or separate. Analyses indicate that the economic foundations of cohabiting couples' union transitions do not lie in economic specialization or only men's ability to be good providers. Instead, results for marriage support marriage bar theory: adjusting for couples' absolute earnings, increases in wealth and couples' earnings relative to a standard associated with marriage strongly predict marriage. For dissolution, couples with higher and more equal earnings are significantly less likely to separate. Findings demonstrate that within couple earnings equality promotes stability, and between-couple inequalities in economic resources are critical in producing inequalities in couples' relationship outcomes.

AB - Autophagy is a fundamental cellular catabolic pathway mediating the recycling of cellular components. Autophagy has been implicated in pathogenesis of diverse diseases such as neurodegeneration and cancer. Due to the therapeutic potential, the autophagy-modulating agents have profoundly enriched the spectrum of tools used to investigate autophagy. However, many of these compounds have additional off-target effects that may confound elucidation of autophagy in certain contexts. There remains high demand for highly specific and novel chemotypes that can be used to study the regulation mechanism of autophagy and contribute novel pharmacophores for therapeutic purposes. Here, we describe a cell-based quantitative high-content screening (HCS) for autophagy inhibitors using a human breast adenocarcinoma MCF7 cell line stably expressing EGFP-LC3, a bona fide marker of autophagy.

AB - We fabricated a miniaturized electrochemical uric acid biosensor with a 3 aminopropyltriethoxysilane (APTES)-modified indium tin oxide (ITO) microelectrode array (MUEA). The ITO-MUEA on a glass plate was immobilized with the enzyme uricase, through a cross-linker, bis[sulfosuccinimidyl]suberate (BS3). The enzyme immobilized electrode (uricase/BS3/APTES/ITO-MUEA/glass) was characterized by atomic force microscopy and electrochemical techniques. The cyclic voltammetry and impedance studies show an effective binding of uricase at the MUEA surface. The amperometric response of the modified electrode was measured towards uric acid concentration in aqueous solution (pH 7.4), under microfluidic channel made of polydimethylsiloxane. The MUEA biosensor shows a linear response over a concentration range of 0.058 to 0.71 mM with a sensitivity of 46.26 MUA mM-1 cm 2. A response time of 40 s reaching a 95% steady-state current value was obtained. The biosensor retains about 85% of enzyme activity for about 6 weeks. The biosensor using MUEA instead of a large single band of electrode allows the entire core of the channel to be probed though keeping an improved sensitivity with a small volume of sample and reagents. PMID- 29470785 TI - The Abscopal Effect in the Era of Cancer Immunotherapy: a Spontaneous Synergism Boosting Anti-tumor Immunity? AB - Radiotherapy is one of the main treatment strategies used in cancer. Aside from the local control of the disease, which is mediated by a direct cytotoxic effect on tumor cells, radiotherapy has also been shown to exert immune-mediated local and systemic effects. Radiotherapy can elicit anti-tumor responses in distant sites from the radiation field; this phenomenon is known as the abscopal effect and has been described in patients previously treated with immune checkpoint blockade (ICB). Considering that the efficacy of immunotherapy has been demonstrated only in a subset of patients-who often benefit with lasting responses-efforts are ongoing to potentiate its activity with the development of new combination strategies. Radiotherapy might represent a potential candidate for a synergistic combination with immunotherapy, by improving the immunogenicity of tumors and by enhancing local and systemic immune effects. This review aims to summarize the current pre-clinical and clinical data on the immune effects of radiotherapy and their potential implications for cancer immunotherapy.

PMID- 29470788 TI - Commentary: Using Impedance Cardiography to Detect Asymptomatic Cardiovascular Disease in Prehypertensive Adults with Risk Factors. AB - New guidelines on hypertension eliminated the classification of prehypertension and divided those blood pressure (BP) levels into elevated BP and stage 1 hypertension. For elevated BP, this study showed that cardiovascular (CV) abnormalities were prevalent in adults over 40 years of age with at least 2 CV risk factors. Detecting abnormalities of the CV system moves a patient from being at high risk to having earlystage cardiovascular disease (CVD) and supports a decision to treat. By redefining stage 1 and lowering the target BP, the new guidelines have set an ambitious goal for early intervention to prevent progression of CVD. Proper drug selection and titration are critical. Hypertensive patients have diverse CV abnormalities that can be quantified by impedance cardiography. By stratifying patients with ventricular, vascular, and hemodynamic abnormalities, treatment can be customized based on the abnormal underlying mechanisms to rapidly control BP and prevent progression of CVD. PMID- 29470789 TI - Evaluation of Psychometric and Linguistic Properties of the Italian Adolescent Pain Assessment Scales: A Systematic Review. AB - INTRODUCTION: Adolescents' pain experiences are complex and multidimensional, and evaluating pain only from a sensory and affective point of view may be in many instances limiting and inadequate; this is the reason why it is of paramount importance to identify the tools which can better assess the pain experienced by young patients. A person-oriented approach is highly encouraged, as it may better investigate the cognitive and behavioral development typical of this age group. The aim of this review paper is to describe the available tools which are able to adequately assess pain intensity in adolescents, in particular those validated in Italian. METHODS: We conducted a systematic review using four databases: CINAHL, PsycINFO, PubMed and Cochrane, and selected all the articles published between January 1970 and November 2017. We selected all the papers reporting the validation process of pain assessment tools specifically tailored for adolescent patients (age range 10-18 years) and based on psychometric and linguistic parameters, and focused especially on the tools available in Italian and able to measure acute and chronic pain. RESULTS: The results of our investigation have revealed the existence of 40 eligible tools, 17 of which are monodimensional and the remaining 23 multidimensional, more specifically tailored to assess both acute and chronic pain. Some of the instruments (26) were self-reports while others were classified as behavioral (13) and/or mixed. Only one tool turned out to be suitable for fragile adolescents, while six adopted a person-oriented approach that better emphasized the cognitive and behavioral process typical of the adolescent population. None of them has ever been validated in Italian. CONCLUSION: Valid and reliable psychometric tools specifically organized to provide a cultural and linguistic evaluation of the patient are indeed the most recommended instruments to assess the intensity of the pain experienced by the patient, as they may provide useful information to implement a health policy aimed at identifying the best assistance programs. PMID- 29470790 TI - Magnesium corrosion particles do not interfere with the immune function of primary human and murine macrophages. AB - Magnesium is currently under investigation as a prospective biodegradable implant material. Biodegradation of magnesium causes a release of magnesium, hydroxide ions and hydrogen gas but it can also lead to the formation of particulate debris. Implant-derived particles may have immunotoxic effects. To investigate the influence of magnesium-derived particles on the immune functions of primary macrophages, up to 500 MUg/ml magnesium or magnesium corrosion particles were added to the cell culture medium. No major effects were observed on cell viability and on the release of the proinflammatory cytokine tumor necrosis factor (TNF)alpha. In addition, the ability of macrophages to stimulate proliferation of allogenic lymphocytes in a mixed leukocyte reaction remained unaffected. When macrophages were incubated with magnesium particles and then infected with the apathogenic Mycobacterium smegmatis, infection-induced TNFalpha secretion from murine macrophages was inhibited but not from human macrophages. However, the bactericidal activity of either cell type was not influenced. In conclusion, magnesium-related particles did not restrict the immune function of macrophages, suggesting that magnesium implants and corrosion particles derived thereof are highly biocompatible and have a low inflammatory potential. PMID- 29470791 TI - Development of microspheres for biomedical applications: a review. AB - An overview of microspheres manufactured for use in biomedical applications based on recent literature is presented in this review. Different types of glasses (i.e. silicate, borate, and phosphates), ceramics and polymer-based microspheres (both natural and synthetic) in the form of porous , non-porous and hollow structures that are either already in use or are currently being investigated within the biomedical area are discussed. The advantages of using microspheres in applications such as drug delivery, bone tissue engineering and regeneration, absorption and desorption of substances, kinetic release of the loaded drug components are also presented. This review also reports on the preparation and characterisation methodologies used for the manufacture of these microspheres. Finally, a brief summary of the existing challenges associated with processing these microspheres which requires further research and development are presented. PMID- 29470792 TI - Assessment of injectable and cohesive nanohydroxyapatite composites for biological functions. AB - Pressing need for utilization of injectables/fillers in various forms of orthopaedic treatments/surgeries commands an equal demand for better graft material. Injectable bone graft material based on biomimetically synthesized nanohydroxyapatite was developed and subjected to ball milling for different times; three materials thus produced were evaluated for their biological properties. The three composites tested were found to have some difference in proliferation and differentiation on mesenchymal stem cells in cultures. In vivo studies were performed by implanting the graft materials with or without cells in the bone drill hole injury created in the femur of Wistar rats. Our studies show that the composites lead to well-healed injury site with normal histology without inflammation or fibrous tissue formation and bone deformity. This material needs to be tested on large animals for further ascertaining its applicability in clinical use. PMID- 29470793 TI - Designing casein-coated iron oxide nanostructures (CCIONPs) as superparamagnetic core-shell carriers for magnetic drug targeting. AB - Magnetic drug targeting is a drug delivery system applicable to cancer treatment. Coated magnetic particles, called carriers, are very useful for delivering chemotherapeutic drugs. In the present research, casein-coated iron oxide nanocarriers (CCIONPs) of core shell nanostructure have been described as being applicable to magnetic drug targeting. The structure, morphology, and composition of prepared magnetic nanoparticles were determined by analytical techniques like Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), scanning electron microscopy (SEM), Electron diffraction (ED), X-ray diffraction (XRD), Zeta potential, Dynamic light scattering (DLS), Mossbauer and Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), Vibrating sample magnetometery (VSM)) and in vitro cytotoxicity analysis. Magnetization studies of CCIONPs conducted at room temperature using a vibrating sample magnetometer suggested their superparamagnetic nature as having a saturation magnetization (Ms) of 64 emu g-1 at an applied magnetic field of 5 kOe. The size of the magnetic polymeric nanoparticles was found to lie in the range of 73.9 +/-0.36 nm, and the particles exhibited superparamagnetic behavior. The prepared particles could be used as a drug carrier for controlled and targeted drug delivery.

PMID- 29470795 TI - Assessment of lactoferrin-conjugated solid lipid nanoparticles for efficient targeting to the lung. AB - The aim of the present study was to develop a target oriented drug delivery system for the lungs. Lactoferrin (Lf)-coupled solid lipid nanoparticles (SLNs) bearing rifampicin was prepared by a solvent injection method. The prepared nanoparticles were characterized for shape, particle size, polydispersity and percentage drug entrapment. An optimized formulation was then studied for its in vivo performance in animals and to determine its targeting efficiency. It was observed that, upon coupling with Lf, the size of SLNs increased while the percent entrapment efficiency decreases. In in vitro release, determined by a dialysis technique, analysis showed that uncoupled SLNs exhibited higher drug release as compared to coupled SLNs. An in vivo biodistribution study shows 47.7 +/-0.4 drug uptakes by the lungs, which was 3.05 times higher in comparison to uncoupled SLNs. These biodistribution studies are further supported by the fluorescence study that revealed enhanced uptake of Lf-coupled SLNs in the lung. From the presented results, it can be concluded that Lf-coupled SLNs enhanced drug uptake in the lung. Moreover, lactoferrin is an efficient molecule that can be used for targeting active agents directly to the lung. PMID- 29470796 TI - Peers influence adolescent reward processing, but not response inhibition. AB - Most adolescent risk taking occurs in the presence of peers. Prior research suggests that peers alter adolescents' decision making by increasing reward sensitivity and the engagement of regions involved in the processing of rewards, primarily the striatum. However, the potential influence of peers on the capacity for impulse control, and the associated recruitment of the brain's control circuitry, has not yet been adequately examined. In the current study, adolescents underwent functional neuroimaging while they completed interleaved rounds of risk-taking and response-inhibition tasks. Social context was manipulated such that the participants believed they were either playing alone and unobserved, or watched by an anonymous peer. Compared to those who completed the tasks alone, adolescents in the peer condition took more risks during the risk-taking task and exhibited relatively heightened activation of the striatum. Activity within this striatal region also predicted individual differences in overall risk taking. In contrast, the presence of peers had no effect on behavioral response inhibition and had minimal impact on the engagement of typical cognitive control regions. In a subregion of the anterior insula engaged mutually by both tasks, activity was again found to be sensitive to social context during the risk-taking task, but not during the response-inhibition task. These findings extend the evidence that the presence of peers biases adolescents towards risk taking by increasing reward sensitivity rather than disrupting cognitive control. PMID- 29470797 TI - Body mass index is independently associated with xanthine oxidase activity in overweight/obese population. AB - PURPOSE: The pathophysiological mechanism of the relationship between xanthine oxidase (XO) activity and obesity has not been completely elucidated. Since inflammation and oxidative stress are regarded as key determinants of enlarged adipose tissue, we aimed to investigate the association between oxidative stress (as measured with XO activity), inflammation [as measured with high-sensitivity C reactive protein (hsCRP)] and obesity [as measured with body mass index (BMI)]. In addition, we wanted to examine whether hsCRP itself plays an independent role in XO activity increase or it is only mediated through obesity. METHODS: A total of 118 overweight/obese volunteers (mean age 54.76 +/- 15.13 years) were included in the current cross-sectional study. Anthropometric, biochemical parameters, and blood pressure were obtained. RESULTS: Significant differences between age, BMI, waist circumference, concentrations of uric acid and hsCRP, as well as xanthine dehydrogenase (XDH) activities were evident among XO tertile groups. Multiple linear regression analysis revealed that BMI (beta = 0.241, p = 0.012) and XDH (beta = - 0.489, p < 0.001) are the independent predictors of XO activity (R2 adjusted = 0.333), whereas hsCRP lost its independent role in XO activity prediction. CONCLUSION: Obesity (as determined with increased BMI) is an independent predictor of high XO activity in overweight/obese population. LEVEL OF EVIDENCE: Level V: cross-sectional descriptive study. PMID- 29470798 TI - NR4A1 contributes to high-fat associated endothelial dysfunction by promoting CaMKII-Parkin-mitophagy pathways. AB - Parkin-related mitophagy is vital for endothelial cell viability and the development of atherosclerosis, although the upstream regulatory factor underlying Parkin-mediated mitophagy in endothelial apoptosis and atherosclerosis progression remains unknown. In the present study, we demonstrated that nuclear receptor subfamily 4 group A member 1 (NR4A1) is actually expressed in aortic endothelial cells (AECs) under oxidized low-density lipoprotein (ox-LDL) treatment in vitro or isolated from high-fat treated mice in vivo. Higher NR4A1 levels were associated with AEC apoptosis, mitochondrial dysfunction, and energy disorder. At the molecular level, ox-LDL stimulation increased NR4A1 expression, which evoked Parkin-mediated mitophagy. Excessive mitophagy overtly consumed mitochondrial mass, leading to an energy shortage and mitochondrial dysfunction. However, loss of NR4A1 protected AECs against ox-LDL induced apoptosis by inhibiting excessive mitophagy. Furthermore, we also identified that NR4A1 regulated Parkin activation via post-transcriptional modification by Ca2+/calmodulin-dependent protein kinase II (CaMKII). Activated CaMKII via NR4A1 induced the phosphorylated activation of Parkin. In summary, our data support the role of NR4A1/CaMKII/Parkin/mitophagy in AEC apoptosis and atherosclerosis formation and provide new insights into treating atherosclerosis with respect to endothelial viability, mitophagy, and NR4A1. PMID- 29470800 TI - Landiolol: A Review in Tachyarrhythmias. AB - Intravenous landiolol [Rapibloc(r) (EU)], an ultra short-acting highly cardioselective beta1-blocker, is approved in the EU for the rapid short-term control of tachyarrhythmias in the perioperative and intensive care settings. It has long been used in Japan to treat perioperative tachyarrhythmias. The efficacy of landiolol has been demonstrated in a large number of randomized controlled clinical trials. Landiolol significantly reduced heart rate in patients with postoperative or intraoperative supraventricular tachycardia relative to placebo and in those with atrial fibrillation/flutter and left ventricular dysfunction relative to digoxin. It was more effective than diltiazem in converting postoperative atrial fibrillation (POAF) to normal sinus rhythm. Perioperative prophylactic administration of landiolol significantly reduced the incidence of POAF during the first week after cardiac and other surgeries, compared with diltiazem, placebo or no landiolol treatment. Landiolol also attenuated adverse haemodynamic and other responses to invasive procedures such as percutaneous coronary intervention, tracheal intubation, extubation and electroconvulsive therapy. Landiolol was generally well tolerated, with a relatively low risk of hypotension and bradycardia. Landiolol has more favourable pharmacological properties than esmolol, a short-acting beta-blocker commonly used for the rapid control of heart rate. Although additional comparative studies are warranted to define the place of landiolol relative to esmolol, current evidence suggest that landiolol is a useful option for the rapid short-term control of tachyarrhythmias. Landiolol offers a simple dosage scheme and is available in two easy-to-use formulations (concentrate and powder).

PMID- 29470801 TI - Episodic Breathlessness in Patients with Advanced Cancer: Characteristics and Management. AB - The aim of this review is to present the way in which episodic breathlessness (EB) has been recognized over the years, with regard to definition, characteristics, and management of these acute episodes that have serious consequences for patients. EB is characterized by a sudden increase in intensity of dyspnea over a short duration of time, leading to high levels of anxiety. A significant aggravation of dyspnea may occur in patients with a background of dyspnea or intermittently even without basal breathlessness. Often, known precipitating factors may trigger EB. Flares of breathlessness are accompanied by degrees of psychological distress, although it is unclear whether psychological factors may precede or be induced by EB. In any case, there is a reinforcing circuit. The duration of EB ranges from 10-30 min. Given the specific temporal pattern, requiring rapid intervention, substances with a short onset of action are suitable to overlap this phenomenon. Short-onset opioids could provide a clinical effect overlapping the onset and duration of an episode, resembling what has been largely reported for breakthrough pain. Although data are still insufficient to suggest specific recommendations, strategies such as avoiding exertion, pacing or using devices, or keeping calm have been described. Few controlled studies have investigated the effects of different formulations of opioids. Some data were gathered from studies assessing the pre-emptive use of rapid onset opioids, such as transmucosal preparations of fentanyl, followed by a provocative test, while other studies attempted to reproduce real-life conditions, given as needed. All these trials were insufficiently powered to address the efficacy of fentanyl products over oral morphine or placebo, reflecting the difficulties in patient recruiting and finalizing the studies. Strategies to prevent the occurrence of EB should be taken into consideration, including optimization of the condition of persistent dyspnea or treating psychologic or environmental causes. PMID- 29470802 TI - Male Undergraduates' HPV Vaccination Behavior: Implications for Achieving HPV Associated Cancer Equity. AB - Despite the availability of the human papillomavirus (HPV) vaccine for males, uptake of the vaccine has been low, particularly among young adult males. This study aimed to investigate the levels of HPV vaccination and predictors of HPV vaccine completion in college men ages 18-26. We analyzed data from the 2015 College Student Health Survey, which was administered at 17 post-secondary institutions in Midwest areas. We included only responses from male participants who were ages 18-26 years old, resulting in a sample size of 2516. We used Andersen's Behavioral Model of Health Services Utilization to guide our study design. Multivariate logistic regression was used to examine predictors of HPV vaccine receipt. College-aged males in our sample had a HPV vaccine completion rate of 50.0%. Male students who were younger, had at least one parent who held a graduate degree, had initiated sex, and were enrolled at a private 4-year institution were more likely to have been vaccinated. These findings suggest that HPV vaccination in college-aged men are low. Efforts are needed to increase HPV vaccination in male students who are older, from lower socioeconomic statuses, have not initiated sex, and enrolled at public institutions. Findings also indicate important gender disparities in vaccine uptake that must be addressed in order to achieve optimal vaccine uptake in college-aged males.

AB - PURPOSE: The aim of this systematic review is to assess the effect of different types of exercise on breast cancer-related lymphedema (BCRL) in order to elucidate the role of exercise in this patient group. METHODS: A systematic data search was performed using PubMed (December 2016). The review is focused on the rehabilitative aspect of BCRL and undertaken according to the PRISMA statement with Levels of Evidence (LoE) assessed. RESULTS: 11 randomized controlled trials (9 with LoE 1a and 2 with LoE 1b) that included 458 women with breast cancer in aftercare were included. The different types of exercise consisted of aqua lymph training, swimming, resistance exercise, yoga, aerobic, and gravity-resistive exercise. Four of the studies measured a significant reduction in BCRL status based on arm volume and seven studies reported significant subjective improvements. No study showed adverse effects of exercise on BCRL. CONCLUSION: The evidence indicates that exercise can improve subjective and objective parameters in BCRL patients, with dynamic, moderate, and high-frequency exercise appearing to provide the most positive effects. PMID- 29470805 TI - Adjuvant versus neoadjuvant chemotherapy in triple-negative breast cancer patients with BRCA mutations. AB - PURPOSE: As triple-negative breast cancers are associated with earlier recurrences and poorer survival, optimal treatment of early-stage breast cancer is essential. Several retrospective studies in triple-negative breast cancer have reported conflicting results in overall survival in patients receiving neoadjuvant or adjuvant systemic therapy. This study aims to analyze outcomes of adjuvant versus neoadjuvant in patients with early-stage triple-negative breast cancer with and without BRCA germline mutations. METHODS: Patients with stage I or II triple-negative breast cancer who had BRCA testing were identified from a prospective cohort study of 4027 patients. Clinical, demographic, genetic test results, chemotherapy, recurrence, and survival data were analyzed. Overall survival and disease-free survival were estimated using the Kaplan-Meier method. RESULTS: 319 patients with stage I and II triple-negative breast cancer who met eligibility criteria were included in the analysis. 187 received adjuvant chemotherapy (58.6%) and 132 received neoadjuvant chemotherapy (41.4%). 135 were BRCA positive (42.3%) and 184 were BRCA negative (57.7%). There was no significant association between overall survival or disease-free survival and treatment with neoadjuvant versus adjuvant in the overall cohort. Furthermore, there were no significant differences between patient subgroups (neoadjuvant BRCA positive, neoadjuvant BRCA negative, adjuvant BRCA positive, and adjuvant BRCA negative) with respect to either overall survival or disease-free survival. CONCLUSIONS: Neoadjuvant versus adjuvant with standard anthracycline- and taxane containing regimens results in similar disease-free survival and overall survival among patients with stage I and II triple-negative breast cancer regardless of BRCA status. Further studies are needed to evaluate whether similar results are observed with newer agents. PMID- 29470806 TI - Screening of over 1000 Indian patients with breast and/or ovarian cancer with a multi-gene panel: prevalence of BRCA1/2 and non-BRCA mutations. AB - PURPOSE: Breast and/or ovarian cancers are among the most common cancers in women across the world. In the Indian population, the healthcare burden of breast and/or ovarian cancers has been steadily rising, thus stressing the need for early detection, surveillance, and disease management measures. However, the burden attributable to inherited mutations is not well characterized. METHODS: We sequenced 1010 unrelated patients and families from across India with an indication of breast and/or ovarian cancers, using the TruSight Cancer panel which includes 14 genes, strongly associated with risk of hereditary breast and/or ovarian cancers. Genetic variations were identified using the StrandNGS software and interpreted using the StrandOmics platform. RESULTS: We were able to detect mutations in 304 (30.1%) cases, of which, 56 mutations were novel. A majority (84.9%) of the mutations were detected in the BRCA1/2 genes as compared to non-BRCA genes (15.1%). When the cases were stratified on the basis of age at diagnosis and family history of cancer, the high rate of 75% of detection of hereditary variants was observed in patients whose age at diagnosis was below 40 years and had first-degree family member(s) affected by breast and/or ovarian cancers. Our findings indicate that in the Indian population, there is a high prevalence of mutations in the high-risk breast cancer genes: BRCA1, BRCA2, TP53, and PALB2. CONCLUSION: In India, socioeconomic inequality limiting access to treatment is a major factor towards increased cancer burden; therefore, incorporation of a cost-effective and comprehensive multi-gene test will be helpful in ensuring widespread implementation of genetic screening in the clinical practice for hereditary breast and/or ovarian cancers. PMID- 29470807 TI - Longitudinal Effects of Adjuvant Endocrine Therapy on the Quality of Life of Post menopausal Women with Non-metastatic ER+ Breast Cancer: A Systematic Review. AB - BACKGROUND: Anti-estrogen (ER) endocrine therapy is an effective treatment strategy in reducing breast cancer mortality. This therapy has a better therapeutic index than chemotherapy but can still affect patients' quality of life (QOL) over time. OBJECTIVE: The objectives of this systematic review were to (1) describe QOL instruments used in ER-positive (ER+) non-metastatic breast cancer trials and (2) document the longitudinal effects of adjuvant endocrine therapy on the QOL of post-menopausal women with ER+ non-metastatic breast cancer. METHODS: We searched three electronic bibliographic databases for articles published from inception to October 2017 that described (1) a randomized controlled trial (RCT) of non-metastatic breast cancer containing an adjuvant endocrine regimen in at least one arm; (2) the use of a patient self-report measure assessing general or breast cancer-specific QOL; and (3) QOL outcomes at multiple time points during follow-up of at least 5 years. All included trials were independently evaluated by two reviewers, and data were extracted using standardized forms. RESULTS: In total, 13 studies met our inclusion criteria and were assessed in this review. The quality of the trials was reasonably good. The top three most commonly used QOL instruments in the trials were the Functional Assessment of Cancer Therapy/Functional Assessment of Chronic Illness Therapy, the Short Form-36 and the Menopause-Specific Quality of Life. Most studies found no differences between tamoxifen and aromatase inhibitor groups in terms of global QOL. QOL data affected treatment regimen recommendations in a few cases. A meta-analysis was not feasible because the RCTs included in our review varied in terms of sample size, comparators, QOL instrument used, and timing of QOL measurement. Additionally, as no search strategy has perfect sensitivity, specificity and accuracy, there is always a chance that potentially relevant articles were missed. CONCLUSION: This systematic review suggests that the QOL of post-menopausal women is unlikely to be adversely affected by long-term use of adjuvant endocrine therapy. Efforts are needed to improve the quality of QOL reporting in clinical trials. PMID- 29470808 TI - Comparative Analysis of Recruitment Strategies in a Study of Men Who Have Sex with Men (MSM) in Metropolitan Detroit. AB - HIV/AIDS-related research requires recruitment of representative samples of MSM; yet, we know little about the comparative yield, diversity and cost-benefit tradeoffs between different recruitment venues. We compared 11 recruitment venues used for nine HIV prevention-related focus groups with MSM in Metropolitan Detroit. Of the 64 participants, 24 were clients recruited via an HIV/AIDS focused nonprofit, 20 from Grindr advertisements, 6 from university-student email lists, and 5 from flyers/palmcards. Significantly more African-American, low income and HIV-positive participants were recruited via the nonprofit. The best cost-benefit tradeoffs were for organizational Facebook posts, email groups, personal networking, and nonprofit recruitment. Grindr increased the size of the sample, though at greater expense. Facebook and Scruff advertisements and gay bar outreach represented greater costs than benefits. Only 11.6% of Grindr respondents attended the focus groups. A mix of online and offline recruitment venues can generate a large and diverse sample of MSM, but venue performance is uneven. PMID- 29470810 TI - Diversity of Anopheles spp. (Diptera: Culicidae) in an Amazonian Urban Area. AB - The genus Anopheles encompasses several species considered as vectors of human infecting Plasmodium. Environmental changes are responsible for behavior changes in these vectors and therefore the pattern of malaria transmission. To better understand the dynamics of malaria transmission, this study aimed at identify the species of adult anophelines found in a malaria endemic urban area of the Amazon region, Mancio Lima, located in the Acre State Brazil. Using Shannon-type light traps installed at 11 collection points near fish ponds, a total of 116 anophelines were collected belonging to nine species. Anopheles darlingi Root 1926 and An. albitarsis s.l. Lynch-Arribalzaga 1878 were the most abundant and predominant species. Despite the low number of captured adult anophelines, the occurrence of An. darlingi throughout all urban area and the presence of secondary vectors reinforce the need of a permanent and continuous entomological surveillance.

PMID- 29470809 TI - Receiving HIV Serostatus Disclosure from Partners Before Sex: Results from an Online Survey of Chinese Men Who Have Sex with Men. AB - HIV serostatus disclosure before sex can facilitate serosorting, condom use and potentially decrease the risk of HIV acquisition. However, few studies have evaluated HIV serostatus disclosure from partners before sex. We examined the rate and correlates of receiving HIV serostatus disclosure from regular and casual male partners before sex among an online sample of men who have sex with men (MSM) in China. An online cross-sectional study was conducted among MSM in eight Chinese cities in July 2016. Participants completed questions covering sociodemographic information, sexual behaviors, HIV testing (including HIV self testing) history, self-reported HIV status, and post-test violence. In addition, participants were asked whether they received HIV serostatus disclosure from their most recent partners before sex. Overall, 2105 men completed the survey. Among them, 85.9% were never married, and 35.4% had high school or less education. A minority (20.6%, 346/1678; 17.8%, 287/1608) of men received HIV serostatus disclosure from their most recent regular and casual male partners, respectively. Multivariate analysis indicated that participants who ever self tested for HIV were more likely to have received HIV status disclosure from regular [adjusted OR (aOR) = 1.92, 95% CI 1.50-2.44] and casual (aOR = 2.34, 95% CI 1.80-3.04) male partners compared to never self-tested participants. Compared to participants who had not received HIV status disclosure from regular partners, participants who received disclosure from regular male partners had higher likelihood in experiencing post-test violence (aOR = 5.18, 95% CI 1.53-17.58). Similar results were also found for receiving HIV serostatus disclosure from casual partners. This study showed that HIV serostatus disclosure from partners was uncommon among Chinese MSM. Interventions and further implementation research to facilitate safe disclosure are urgently needed for MSM.

AB - Objectives Pacific Islanders are disproportionately burdened by poorer perinatal health outcomes with higher rates of pre-term births, low birth weight babies, infant mortality, and inadequate or no prenatal care. The aim of this study is to examine Marshallese mothers' beliefs, perceptions, and experiences of prenatal care and to identify potential barriers. Methods Three focus groups were conducted with Marshallese mothers, who were 18 years or older, and living in Arkansas. Focus groups focused on mothers' beliefs, perceptions, and experiences of prenatal care. A thematic qualitative analysis was conducted to identify salient themes within the data. Results The results demonstrated that negotiating health insurance, transportation, and language barriers were all major structural barriers that constrain prenatal care. The social-cultural barriers that emerged included a lack of understanding of the importance of seeking early and consistent prenatal care, as well as how to navigate the healthcare process. The more complicated challenges that emerged were the feelings of shame and embarrassment due to the perception of their age or being unmarried during pregnancy not being acceptable in American culture. Furthermore, the participants described perceived discrimination from prenatal care providers. Lastly, the participants described fear as a barrier to seeking out prenatal care. Conclusions for Practice This study identified both structural and socio-cultural barriers that can be incorporated into suggestions for policy makers to aid in alleviating maternal health disparities among Pacific Islander women. Further research is needed to address the Marshallese mothers' perceived discrimination from maternal health care providers.

AB - Objectives Training healthcare professionals in emergency maternal healthcare is a critical component of improving overall maternal health in developing countries like Rwanda. This paper explored the challenges that healthcare professionals who participated in a Continuing Professional Development (CPD) program on Advanced Life Support in Obstetrics(r) (ALSO) face in putting the learned knowledge and skills into practice in hospitals of Rwanda. Methods This study used a mixed methods approach to understand the challenges/barriers to applying new knowledge and skills in the hospitals of Rwanda. We conducted thirteen purposive in-depth interviews with ALSO(r) trainees (nurses, midwives and physicians) complemented with a cross-sectional survey on staff turnover in eight of the nine hospitals in the Eastern province of Rwanda. Results Our study found that trainees do not get enough opportunity to apply the new knowledge and skills in their hospitals and expand to health centers. In part because they are frequently rotating to different departments of the hospital and are not getting the opportunity to train their colleagues to share the learned knowledge and skills. The lack of refresher trainings/mentorship and the high personnel turnover were also reported as a barrier to applying new knowledge and skills. Reasons for staff turnover included pursuing further studies, a better opportunity (job/remuneration), low morale, and family related motives including joining a spouse or better schools for children. Conclusions for Practice Expanding and formalizing CPD training to all the healthcare professionals involved in providing maternal care services would improve the provision of emergency maternal healthcare in Rwanda.

AB - MicroRNA is a novel class of small noncoding RNA that has been implicated in a variety of physiological and pathological processes, including glucose homeostasis and diabetes mellitus. So far, a few studies have reported that miRNAs may be an important regulator in glucose-stimulated insulin secretion (GSIS) pathway. However, the role of miRNAs in this process remains unclear. The levels of miRNAs in mouse islets and MIN6 cells were determined by quantitative RT-PCR. Concentration of insulin was determined by ELISA, and the expression of the target protein was determined with western blot assay. The overexpression and downregulation of miRNAs in MIN6 were conducted using cell transfection methods. And luciferase assay was used to measure the direct interaction between miRNAs and target messenger RNAs 3'UTR. miR-9 was screened out for it was downregulated under the effects of short-term high glucose, while long-term high glucose relatively increased miR-9 expression. The Stxbp1 expression was decreased with the overexpression of miR-9 in MIN6 cells and increased when miR-9 was downregulated. Moreover, it was verified by luciferase assay that miR-9 regulated Stxbp1 gene expression by directly targeting Stxbp1 messenger RNA 3'UTR. This study suggests that the pathway consisting of miR-9 and Stxbp1 plays a key role in beta-cell function, thus contributing to the network of miRNA-insulin secretion and offering a new candidate for diabetes therapy.

AB - Squalene is the main unsaponifiable component of virgin olive oil, the main source of dietary fat in Mediterranean diet, traditionally associated with a less frequency of cardiovascular diseases. In this study, two experimental approaches were used. In the first, New Zealand rabbits fed for 4 weeks with a chow diet enriched in 1% sunflower oil for the control group, and in 1% of sunflower oil and 0.5% squalene for the squalene group. In the second, APOE KO mice received either Western diet or Western diet enriched in 0.5% squalene for 11 weeks. In both studies, liver samples were obtained and analyzed for their squalene content by gas chromatography-mass spectrometry. Hepatic distribution of squalene was also characterized in isolated subcellular organelles. Our results show that dietary squalene accumulates in the liver and a differential distribution according to studied model. In this regard, rabbits accumulated in cytoplasm within small size vesicles, whose size was not big enough to be considered lipid droplets, rough endoplasmic reticulum, and nuclear and plasma membranes. On the contrary, mice accumulated in large lipid droplets, and smooth reticulum fractions in addition to nuclear and plasma membranes. These results show that the squalene cellular localization may change according to experimental setting and be a starting point to characterize the mechanisms involved in the protective action of dietary squalene in several pathologies. PMID- 29470818 TI - Variability in Predictions from Online Tools: A Demonstration Using Internet Based Melanoma Predictors. AB - BACKGROUND: Prognostic models are increasingly being made available online, where they can be publicly accessed by both patients and clinicians. These online tools are an important resource for patients to better understand their prognosis and for clinicians to make informed decisions about treatment and follow-up. The goal of this analysis was to highlight the possible variability in multiple online prognostic tools in a single disease. METHODS: To demonstrate the variability in survival predictions across online prognostic tools, we applied a single validation dataset to three online melanoma prognostic tools. Data on melanoma patients treated at Memorial Sloan Kettering Cancer Center between 2000 and 2014 were retrospectively collected. Calibration was assessed using calibration plots and discrimination was assessed using the C-index. RESULTS: In this demonstration project, we found important differences across the three models that led to variability in individual patients' predicted survival across the tools, especially in the lower range of predictions. In a validation test using a single institution data set, calibration and discrimination varied across the three models. CONCLUSIONS: This study underscores the potential variability both within and across online tools, and highlights the importance of using methodological rigor when developing a prognostic model that will be made publicly available online. The results also reinforce that careful development and thoughtful interpretation, including understanding a given tool's limitations, are required in order for online prognostic tools that provide survival predictions to be a useful resource for both patients and clinicians. PMID- 29470819 TI - Adequate Local Control in High-Risk Soft Tissue Sarcoma of the Extremity Treated with Surgery Alone at a Reference Centre: Should Radiotherapy Still be a Standard? AB - BACKGROUND: Established practice for the management of soft tissue sarcoma (STS) of the extremity and trunk wall combines perioperative radiotherapy (RT) with limb-preserving surgery. OBJECTIVE: The aim of this study was to explore whether high-quality surgery at high-volume centers may offer equivalent local control in selected cases, when RT needs to be avoided. METHODS: All consecutive adult cases of primary, high-risk STSs treated in a high-volume reference center over a 12 year timeframe were included, and, on retrospective analysis, were divided into two groups. Group A received RT with surgery, and Group B received surgery alone. The primary endpoint was local recurrence-free survival (LRFS). RESULTS: Overall, 390 patients were included (318 in Group A and 72 in Group B), with a median follow-up of 53 months. The main reasons for avoiding RT were patient choice and technical considerations (vascular bypass or flap reconstruction). No difference in R0 resection was seen between the groups (79% vs. 70%; p = 0.18), but Group A had more G3 tumors (80.5% vs. 68%; p = 0.021). No difference in 5-year LRFS was evident (84% vs. 81%; p = 0.16). CONCLUSIONS: LRFS did not differ between patients with high-risk STSs receiving perioperative RT and those treated with surgery alone. The study was retrospective and omission of RT was largely uncontrolled with inherent bias. Nonetheless, data suggest that in experienced centers, the omission of RT did not diminish local disease outcome. Future studies on a selective approach to RT administration are awaited. PMID- 29470820 TI - The Impact of Intraoperative Re-Resection of a Positive Bile Duct Margin on Clinical Outcomes for Hilar Cholangiocarcinoma. AB - BACKGROUND: The impact of re-resection of a positive intraoperative bile duct margin on clinical outcomes for resectable hilar cholangiocarcinoma (HCCA) remains controversial. We sought to define the impact of re-resection of an initially positive frozen-section bile duct margin on outcomes of patients undergoing surgery for HCCA. METHODS: Patients who underwent curative-intent resection for HCCA between 2000 and 2014 were identified at 10 hepatobiliary centers. Short- and long-term outcomes were analyzed among patients stratified by margin status. RESULTS: Among 215 (83.7%) patients who underwent frozen-section evaluation of the bile duct, 80 (37.2%) patients had a positive (R1) ductal margin, 58 (72.5%) underwent re-resection, and 29 ultimately had a secondary negative margin (secondary R0). There was no difference in morbidity, 30-day mortality, and length of stay among patients who had primary R0, secondary R0, and R1 resection (all p > 0.10). Median and 5-year survival were 22.3 months and 23.3%, respectively, among patients who had a primary R0 resection compared with 18.5 months and 7.9%, respectively, for patients with an R1 resection (p = 0.08). In contrast, among patients who had a secondary R0 margin with re-resection of the bile duct margin, median and 5-year survival were 30.6 months and 44.3%, respectively, which was comparable to patients with a primary R0 margin (p = 0.804). On multivariable analysis, R1 margin resection was associated with decreased survival (R1: hazard ratio [HR] 1.3, 95% confidence interval [CI] 1.0 1.7; p = 0.027), but secondary R0 resection was associated with comparable long term outcomes as primary R0 resection (HR 0.9, 95% CI 0.4-2.3; p = 0.829). CONCLUSIONS: Additional resection of a positive frozen-section ductal margin to achieve R0 resection was associated with improved long-term outcomes following curative-intent resection of HCCA. PMID- 29470821 TI - Is EQ-5D-5L Better Than EQ-5D-3L? A Head-to-Head Comparison of Descriptive Systems and Value Sets from Seven Countries. AB - OBJECTIVE: This study describes the first empirical head-to-head comparison of EQ 5D-3L (3L) and EQ-5D-5L (5L) value sets for multiple countries. METHODS: A large multinational dataset, including 3L and 5L data for eight patient groups and a student cohort, was used to compare 3L versus 5L value sets for Canada, China, England/UK (5L/3L, respectively), Japan, The Netherlands, South Korea and Spain. We used distributional analyses and two methods exploring discriminatory power: relative efficiency as assessed by the F statistic, and an area under the curve for the receiver-operating characteristics approach. Differences in outcomes were explored by separating descriptive system effects from valuation effects, and by exploring distributional location effects. RESULTS: In terms of distributional evenness, efficiency of scale use and the face validity of the resulting distributions, 5L was superior, leading to an increase in sensitivity and precision in health status measurement. When compared with 5L, 3L systematically overestimated health problems and consequently underestimated utilities. This led to bias, i.e. over- or underestimations of discriminatory power. CONCLUSION: We conclude that 5L provides more precise measurement at individual and group levels, both in terms of descriptive system data and utilities. The increased sensitivity and precision of 5L is likely to be generalisable to longitudinal studies, such as in intervention designs. Hence, we recommend the use of the 5L across applications, including economic evaluation, clinical and public health studies. The evaluative framework proved to be useful in assessing preference based instruments and might be useful for future work in the development of descriptive systems or health classifications. PMID- 29470822 TI - The concept of the CCN protein family revisited: a centralized coordination network. AB - The wide array of biological properties attributed to the CCN family of proteins (Perbal in Lancet 363(9402):62-64, 2004) led me to reconsider the possible relationship and roles that these proteins may play as a team, instead of acting on their own as individual regulators in various signaling pathways. The dynamic model which I present in this review stems from the contribution of the biological properties that we established for CCN3, one of the three founding members of the CCN family, which was identified by our group as the first CCN protein showing growth inhibitory properties (1992), expressed mainly in quiescent cells (1996), and showing anti-tumor activities in several cellular models both ex vivo and in vivo. At the present time CCN3 is the only member of the family that has been reported to negatively act on the progression of the cell cycle. The unique dual localisation of CCN3 in the nucleus and outside cells, either at the membrane or in the extracellular matrix, that I first established in 1999, and that now appears to be shared by several other CCN proteins, is a unique essential feature which can no longer be ignored. Based on the structural and functional properties of CCN3, shared by most of the CCN family members, I propose an " all in one " concept in which CCN proteins are team members with specific functions that are aimed at the same goal. This model accounts both for the functional specificity of the various CCN proteins, their sequential and opposite or complementary effects in various biological context, and for the biological consequences of their physical interaction and biological cross-regulation. PMID- 29470824 TI - Turning Up the Heat: An Evaluation of the Evidence for Heating to Promote Exercise Recovery, Muscle Rehabilitation and Adaptation. AB - Historically, heat has been used in various clinical and sports rehabilitation settings to treat soft tissue injuries. More recently, interest has emerged in using heat to pre-condition muscle against injury. The aim of this narrative review was to collate information on different types of heat therapy, explain the physiological rationale for heat therapy, and to summarise and evaluate the effects of heat therapy before, during and after muscle injury, immobilisation and strength training. Studies on skeletal muscle cells demonstrate that heat attenuates cellular damage and protein degradation (following in vitro challenges/insults to the cells). Heat also increases the expression of heat shock proteins (HSPs) and upregulates the expression of genes involved in muscle growth and differentiation. In rats, applying heat before and after muscle injury or immobilisation typically reduces cellular damage and muscle atrophy, and promotes more rapid muscle growth/regeneration. In humans, some research has demonstrated benefits of microwave diathermy (and, to a lesser extent, hot water immersion) before exercise for restricting muscle soreness and restoring muscle function after exercise. By contrast, the benefits of applying heat to muscle after exercise are more variable. Animal studies reveal that applying heat during limb immobilisation attenuates muscle atrophy and oxidative stress. Heating muscle may also enhance the benefits of strength training for improving muscle mass in humans. Further research is needed to identify the most effective forms of heat therapy and to investigate the benefits of heat therapy for restricting muscle wasting in the elderly and those individuals recovering from serious injury or illness. PMID- 29470825 TI - Effect of Resistance Training Frequency on Gains in Muscular Strength: A Systematic Review and Meta-Analysis. AB - BACKGROUND: Current recommendations on resistance training (RT) frequency for gains in muscular strength are based on extrapolations from limited evidence on the topic, and thus their practical applicability remains questionable. OBJECTIVE: To elucidate this issue, we conducted a systematic review and meta analysis of the studies that compared muscular strength outcomes with different RT frequencies. METHODS: To carry out this review, English-language literature searches of the PubMed/MEDLINE, Scopus, and SPORTDiscus databases were conducted. The meta-analysis was performed using a random-effects model. The meta-analysis models were generated with RT frequencies classified as a categorical variable as either 1, 2, 3, or 4+ times/week, or, if there were insufficient data in subgroup analyses, the training frequencies were categorized as 1, 2, or 3 times/week. Subgroup analyses were performed for potential moderators, including (1) training volume; (2) exercise selection for the 1 repetition maximum (RM) test (for both multi-joint and single-joint exercises); (3) upper and lower body strength gains; (4) training to muscular failure (for studies involving and not involving training to muscular failure); (5) age (for both middle-aged/older adults and young adults); and (6) sex (for men and for women). The methodological quality of studies was appraised using the modified Downs and Black checklist. RESULTS: A total of 22 studies were found to meet the inclusion criteria. The average score on the Downs and Black checklist was 18 (range 13-22 points). Four studies were classified as being of good methodological quality, while the rest were classified as being of moderate methodological quality. Results of the meta analysis showed a significant effect (p = 0.003) of RT frequency on muscular strength gains. Effect sizes increased in magnitude from 0.74, 0.82, 0.93, and 1.08 for training 1, 2, 3, and 4+ times per week, respectively. A subgroup analysis of volume-equated studies showed no significant effect (p = 0.421) of RT frequency on muscular strength gains. The subgroup analysis for exercise selection for the 1RM test suggested a significant effect of RT frequency on multi-joint (p < 0.001), but not single-joint, 1RM test results (p = 0.324). The subgroup analysis for upper and lower body showed a significant effect of frequency (p = 0.004) for upper body, but not lower body, strength gains (p = 0.070). In the subgroup analysis for studies in which the training was and was not carried out to muscular failure, no significant effect of RT frequency was found. The subgroup analysis for the age groups suggested a significant effect of training frequency among young adults (p = 0.024), but not among middle-aged and older adults (p = 0.093). Finally, the subgroup analysis for sex indicated a significant effect of RT frequency on strength gains in women (p = 0.030), but not men (p = 0.190). CONCLUSIONS: The results of the present systematic review and meta-analysis suggest a significant effect of RT frequency as higher training frequencies are translated into greater muscular strength gains. However, these effects seem to be primarily driven by training volume because when the volume is equated, there was no significant effect of RT frequency on muscular strength gains. Thus, from a practical standpoint, greater training frequencies can be used for additional RT volume, which is then likely to result in greater muscular strength gains. However, it remains unclear whether RT frequency on its own has significant effects on strength gain. It seems that higher RT frequencies result in greater gains in muscular strength on multi-joint exercises in the upper body and in women, and, finally, in contrast to older adults, young individuals seem to respond more positively to greater RT frequencies. More evidence among resistance-trained individuals is needed as most of the current studies were performed in untrained participants. PMID- 29470826 TI - Small papillary thyroid carcinoma with minimal extrathyroidal extension should be managed as ATA low-risk tumor. AB - PURPOSE: According to American Thyroid Association (ATA) guideline, papillary thyroid cancer (PTC) with minimal extrathyroidal extension (mETE) is classified at "intermediate risk" of persistent/recurrent disease. However, the impact of mETE per se on patients' outcome is not fully understood. The aim of our study was to evaluate the prognostic significance of mETE in patients with PTC not submitted to therapeutic or prophylactic lymph node dissection, according to tumor size and other prognostic factors. PATIENTS AND METHODS: We retrospectively evaluated a total of 514 PTC patients: 127 (24.7%) had mETE (pT3Nx) and 387 (75.3%) had negative margins (pT1-2Nx). At a median follow-up of 9.1 years, patients were divided in two groups: patients with "good outcome" (no evidence of disease) and patients with "poor outcome" (persistent structural disease or recurrent disease or tumor-related death). RESULTS: The rate of patients with "poor outcome" was significantly higher in patients with mETE compared with patients with negative margins (11.8 versus 5.1%; OR 2.4576, 95% CI 1.2178 4.9594, p = 0.01). However, mETE was significantly associated with poor outcome only in patients with tumors larger than 1.5 cm. CONCLUSIONS: mETE is an unfavorable prognostic factor in tumors larger than 1.5 cm, suggesting that, in the absence of other unfavorable characteristics, smaller tumors with mETE should be classified and managed as "low risk" tumors.

AB - The aim of this study was an in vitro evaluation and comparison of the cytotoxic effects of free nisin and nisin-loaded PLA-PEG-PLA nanoparticles on gastrointestinal (AGS and KYSE-30), hepatic (HepG2), and blood (K562) cancer cell lines. To create this novel anti-cancer drug delivery system, the nanoparticles were synthesized and then loaded with nisin. Subsequently, their biocompatibility, ability to enter cells, and physicochemical properties, including formation, size, and shape, were studied using hemolysis, fluorescein isothiocyanate (FITC), Fourier transform infrared (FTIR) spectroscopy, dynamic light scattering (DLS), and scanning electron microscopy (SEM), respectively. Then, its loading efficiency and release kinetics were examined to assess the potential impact of this formulation for the nanoparticle carrier candidacy. The cytotoxicities of nisin and nisin-loaded nanoparticles were evaluated by using the MTT and Neutral Red (NR) uptake assays. Detections of the apoptotic cells were done via Ethidium Bromide (EB)/Acridine Orange (AO) staining. The FTIR spectra, SEM images, and DLS graph confirmed the formations of the nanoparticles and nisin-loaded nanoparticles with spherical, distinct, and smooth surfaces and average sizes of 100 and 200 nm, respectively. The loading efficiency of the latter nanoparticles was about 85-90%. The hemolysis test represented their non cytotoxicities and the FITC images indicated their entrance inside the cells. An increase in the percentage of apoptotic cells was observed through EB/AO staining. These results demonstrated that nisin had a cytotoxic effect on AGS, KYSE-30, HepG2, and K562 cancer cell lines, while the cytotoxicity of nisin loaded nanoparticles was more than that of the free nisin. PMID- 29470828 TI - Enhancement of Dissolution and Skin Permeability of Pentazocine by Proniosomes and Niosomal Gel. AB - Proniosomes (PN) are the dry water-soluble carrier systems that may enhance the oral bioavailability, stability, and topical permeability of therapeutic agents. The low solubility and low oral bioavailability due to extensive first pass metabolism make Pentazocine as an ideal candidate for oral and topical sustained release delivery. The present study was aimed to formulate the PNs by quick slurry method that are converted to niosomes (liquid dispersion) by hydration, and subsequently formulated to semisolid niosomal gel. The PNs were found in spherical shape in the SEM and stable in the physicochemical and thermal analysis (FTIR, TGA, and XRD). The quick slurry method produced high recovery (> 80% yield) and better flow properties (theta = 28.1-37.4 degrees ). After hydration, the niosomes exhibited desirable entrapment efficiency (44.45-76.23%), size (4.98 21.3 MUm), and zeta potential (- 9.81 to - 21.53 mV). The in vitro drug release (T100%) was extended to more than three half-lives (2-4 h) and showed good fit to Fickian diffusion indicated by Korsmeyer-Peppas model (n = 0.136-0.365 and R2 = 0.9747-0.9954). The permeation of niosomal gel was significantly enhanced across rabbit skin compared to the pure drug-derived gel. Therefore, the PNs are found promising candidates for oral as dissolution enhancement and sustained release for oral and topical delivery of pentazocine for the management of cancer pain. PMID- 29470829 TI - Enhancing the Therapeutic Efficacy of Tamoxifen Citrate Loaded Span-Based Nano Vesicles on Human Breast Adenocarcinoma Cells. AB - Serious adverse effects and low selectivity to cancer cells are the main obstacles of long term therapy with Tamoxifen (Tmx). This study aimed to develop Tmx-loaded span-based nano-vesicles for delivery to malignant tissues with maximum efficacy. The effect of three variables on vesicle size (Y1), zeta potential (Y2), entrapment efficiency (Y3) and the cumulative percent release after 24 h (Y4) were optimized using Box-Behnken design. The optimized formula was prepared and tested for its stability in different storage conditions. The observed values for the optimized formula were 310.2 nm, - 42.09 mV, 75.45 and 71.70% for Y1, Y2, Y3, and Y4, respectively. The examination using electron microscopy confirmed the formation of rounded vesicles with distinctive bilayer structure. Moreover, the cytotoxic activity of the optimized formula on both breast cancer cells (MCF-7) and normal cells (BHK) showed enhanced selectivity (9.4 folds) on cancerous cells with IC50 values 4.7 +/- 1.5 and 44.3 +/- 1.3 MUg/ml on cancer and normal cells, respectively. While, free Tmx exhibited lower selectivity (2.5 folds) than optimized nano-vesicles on cancer cells with IC50 values of 9.0 +/- 1.1 MUg/ml and 22.5 +/- 5.3 MUg/ml on MCF-7 and BHK cells, respectively. The promising prepared vesicular system, with greater efficacy and selectivity, provides a marvelous tool to overcome breast cancer treatment challenges. PMID- 29470823 TI - Methodological Characteristics and Future Directions for Plyometric Jump Training Research: A Scoping Review. AB - Recently, there has been a proliferation of published articles on the effect of plyometric jump training, including several review articles and meta-analyses. However, these types of research articles are generally of narrow scope. Furthermore, methodological limitations among studies (e.g., a lack of active/passive control groups) prevent the generalization of results, and these factors need to be addressed by researchers. On that basis, the aims of this scoping review were to (1) characterize the main elements of plyometric jump training studies (e.g., training protocols) and (2) provide future directions for research. From 648 potentially relevant articles, 242 were eligible for inclusion in this review. The main issues identified related to an insufficient number of studies conducted in females, youths, and individual sports (~ 24.0, ~ 37.0, and ~ 12.0% of overall studies, respectively); insufficient reporting of effect size values and training prescription (~ 34.0 and ~ 55.0% of overall studies, respectively); and studies missing an active/passive control group and randomization (~ 40.0 and ~ 20.0% of overall studies, respectively). Furthermore, plyometric jump training was often combined with other training methods and added to participants' daily training routines (~ 47.0 and ~ 39.0% of overall studies, respectively), thus distorting conclusions on its independent effects. Additionally, most studies lasted no longer than 7 weeks. In future, researchers are advised to conduct plyometric training studies of high methodological quality (e.g., randomized controlled trials). More research is needed in females, youth, and individual sports. Finally, the identification of specific dose-response relationships following plyometric training is needed to specifically tailor intervention programs, particularly in the long term. PMID- 29470830 TI - Strong enhancement by IGF1-R antagonists of hepatocellular carcinoma cell migration inhibition by Sorafenib and/or vitamin K1. AB - PURPOSE: Emerging evidence indicates that combining Sorafenib with vitamin K1 (VK1) may result in a synergistic inhibition of hepatocellular carcinoma (HCC) cell migration and proliferation. Despite this synergy, its benefits may be limited due to drug resistance resulting from cross-talk with the tumor microenvironment. Insulin-like growth factor-1 (IGF1) signaling acts as an important modulator of HCC cell growth, motility and drug resistance. Therefore, we aimed to explore the effects of Sorafenib in combination with VK1 and/or IGF1 R antagonists on HCC cells. METHODS: Scratch wound migration assays were performed to assess the motility of HCC-derived PLC/PRF/5, HLF and Hep3B cells. The synergistic, additive or antagonistic effects of Sorafenib, VK1 and IGF1-R antagonists on HCC cell motility were assessed using CompuSyn software. The effects mediated by these various compounds on HCC cytoskeleton organization were evaluated using DyLight 554 Phalloidin staining. Proliferation and migration associated signaling pathways were analyzed in PLC/PRF/5 cells using Erk1/2 and Akt activation kits and Western blotting (Mek, JNK, Akt, Paxillin and p38), respectively. RESULTS: The effects of the IGF1-R antagonists GSK1838705A and OSI 906 on HCC cell migration inhibition after Sorafenib and/or VK1 administration, individually or in combination, were evaluated. We found a synergistic effect in PLC/PRF/5, HLF and Hep3B cells for combinations of fixed doses of GSK1838705A or OSI-906 together with different doses of Sorafenib and/or VK1. The levels of synergy were found to be stronger at higher Sorafenib and/or VK1 concentrations and lower or absent at lower concentrations, with some variation among the different cell lines tested. In addition, we found that in PLC/PRF/5 and HLF cells IGF1-R blockage strongly enhanced the reduction and redistribution of F actin induced by Sorafenib and/or VK1 through alterations in the phosphorylation levels of some of the principal proteins involved in the MAPK signaling cascade, which is essential for cell migration. CONCLUSIONS: Our results indicate that modulation of the efficacy of Sorafenib through combinations with VK1 and/or IGF1 R antagonists results in synergistic inhibition of HCC cell migration. PMID- 29470832 TI - Real-World Treatment Patterns for Golimumab and Concomitant Medications in Japanese Rheumatoid Arthritis Patients. AB - INTRODUCTION: The aim of this study was to investigate real-world treatment patterns for use of golimumab and concomitant medications in Japanese patients with rheumatoid arthritis. METHODS: This study was a post hoc retrospective analysis from post-marketing surveillance data on 2350 Japanese patients with moderate/severe rheumatoid arthritis who received golimumab for 24 weeks. The study population was divided based on initiation treatment or dose adjustment patterns with golimumab, methotrexate, or oral glucocorticoids. RESULTS: Logistic regression analysis revealed that the baseline factors associated with administration of golimumab (100 mg) were higher body weight, failure of prior biological therapy (bio-failure), no previous methotrexate use, and respiratory disease, while previous methotrexate use and absence of renal impairment or respiratory disease were associated with concomitant methotrexate therapy, and previous glucocorticoid use was associated with concomitant glucocorticoid therapy. The following associations were identified with regard to dose adjustment during treatment: bio-failure, no previous methotrexate use, previous csDMARDs use, presence of respiratory disease, allergy history, and higher CRP for golimumab dose escalation; shorter disease duration, previous GC, and no previous methotrexate use for methotrexate dose escalation; no prior biological therapy and renal impairment for methotrexate dose reduction; no previous GC use for glucocorticoid dose escalation; and absence of Steinbrocker's stage II/III/IV, absence of Steinbrocker's class II, no bio-failure, and no previous csDMARDs use for glucocorticoid dose reduction. CONCLUSIONS: This study revealed that various baseline factors were associated with initiation of treatment and dose adjustment of golimumab, methotrexate, or oral glucocorticoids, reflecting both the treatment strategies of physicians for improving RA symptoms and/or reducing adverse events.

AB - BACKGROUND: The interplay between the immune system and cancer cells has come to the forefront of cancer therapeutics, with novel immune blockade inhibitors being approved for the treatment of an increasing list of cancers. However, the majority of cancer patients still display or develop resistance to these promising drugs. It is possible that cancer stem cells (CSCs) are contributing to this therapeutic resistance. Although CSCs usually represent a small percentage of the total number of cancer cells, they are endowed with the ability of self renewal and to produce differentiated progeny. Additionally, they have shown the capacity to establish tumors after transplantation to animals, even in small numbers. CSCs have also been found to be resistant to various anti-cancer therapies, including chemotherapy, radiation therapy and, more recently, immunotherapy. This is true despite the sensitivity of CSCs to lysis in vitro by natural killer (NK) cells, the main effector cells of the innate immune system. In this paper the expression of ligands specific for NK cells on CSCs, the intracellular network responsible for the expression of the NK cytotoxicity receptors, and the status of activation of NK cells in the tumor micro environment are reviewed. The aim of this review is to highlight potential strategies for overcoming CSC immune resistance, thereby enhancing the efficacy of current and future anti-cancer therapies. THERAPEUTIC IMPLICATIONS: NK cell activation in the tumor micro-environment through drugs neutralizing inhibitory immune receptors, and combined with other drugs harnessing the potential of the adaptive immune system, could be the most effective approach for attacking both stem cell and non-stem cell cancer populations.

AB - INTRODUCTION: To determine the cost of depression comorbidity among Japanese adults with rheumatoid arthritis (RA). METHODS: A retrospective database study of 8968 patients diagnosed with RA between 2010 and 2015 and treated with any RA medication was conducted. Health care utilization characteristics were compared between patients with and without a comorbidity of depression. Propensity score matching was applied to ensure a balanced comparison between the two cohorts. RESULTS: The prevalence of a depression comorbidity was found for 5% of the total RA patients. This comorbidity was associated with 62% (56%) higher total outpatient visits and 66% (163%) higher rate of emergency room visits after 6 (12) months. CONCLUSIONS: Burden of depression among RA patients in Japan is relatively high and awareness for depression as a comorbidity of RA needs to be reinforced. FUNDING: Janssen Pharmaceutical KK.

AB - INTRODUCTION: Post-marketing surveillance (PMS) is an integral part of monitoring adverse events (AEs) following approval of new drugs. Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). An analysis of PMS reports was conducted to evaluate the safety of tofacitinib in a post-marketing setting. METHODS: Worldwide tofacitinib PMS data received in the Pfizer safety database from November 6, 2012 (first marketing authorization of tofacitinib) to November 5, 2015 were analyzed. Serious AEs (SAEs) of interest were reviewed and reporting rates (RRs) were calculated by dividing the number of SAEs by the estimated 100 patient-years of exposure. Patient exposure was calculated based on estimated worldwide sales and an estimated daily regimen of tofacitinib 5 mg twice daily. RESULTS: During the 3-year reporting period, worldwide post-marketing exposure to tofacitinib since approval was estimated to be 34,223 patient-years. In total, 9291 case reports (82.9% non-serious) were received and 25,417 AEs, 102 fatal cases, and 4352 SAEs were reported. The RRs (per 100 patient-years) for SAEs of interest by Medical Dictionary for Regulatory Activities System Organ Class were 2.57 for infections, 0.91 for gastrointestinal disorders, 0.60 for respiratory disorders, 0.45 for neoplasms, 0.43 for cardiac disorders, and 0.12 for hepatobiliary disorders. CONCLUSIONS: Although there are limitations to these data, no new safety risks were revealed in this real-world setting compared with the safety profile identified in the tofacitinib RA clinical development program. Any risks identified through the tofacitinib development program and PMS will continue to be monitored through pharmacovigilance surveillance. FUNDING: Pfizer Inc.

AB - INTRODUCTION: Granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA) are two related forms of systemic vasculitis. Patients with these conditions often experience relapses affecting various body systems. Here we describe rates of relapse and review healthcare costs resulting from relapse among patients with GPA/MPA. METHODS: Two groups of patients with GPA and MPA were selected from the MarketScan claims databases between 2011 and 2013 based on diagnosis codes. Patients were followed for 12 months to identify relapses based on an algorithm of diagnoses in medical and medication claims. Relapses were categorized into one of the following groups: renal relapse, pulmonary relapse, other relapse-associated condition relapse, GPA or MPA utilization relapse, and mixed relapse. RESULTS: The final sample of patients with GPA and MPA consisted of 2707 and 740 patients, respectively. In both groups, approximately one-quarter of patients experienced relapse during the 12-month follow-up period. The mean all-cause healthcare costs in the 4-month period after relapse were $38,313 (SD, $54,120) for patients with GPA and $35,947 (SD, $48,065) for patients with MPA. In both groups, renal relapses were the costliest. Costs during the 4 months immediately following relapses were substantially higher than what could be expected over a 4-month follow-up among patients who did not experience relapse based on 12-month all-cause costs (GPA, $32,005 [SD, $64,570]; MPA, $61,044 [SD, $125,093]). CONCLUSIONS: Relapses are common among patients with GPA and MPA, and treatment of relapses can be costly. More effective therapies are needed to prevent relapses. FUNDING: Genentech, Inc.

AB - INTRODUCTION: Vancomycin remains the standard of care for invasive methicillin resistant Staphylococcus aureus (MRSA) infections. Treatment failures from heteroresistant vancomycin-intermediate subpopulations (hVISA) are challenging to detect. Minimum inhibitory concentrations (MIC) identified by modified population analysis profile (PAP) is an alternative testing method. The aim of this study was to evaluate the role of PAP MIC on vancomycin failures in two high inoculum infections: MRSA infective endocarditis and pneumonia. METHODS: Retrospective, observational study at Detroit Medical Center from 2008 to 2016. Adults >= 18 years with >= 1 positive MRSA blood culture from IE or pneumonia source and received >= 48 h vancomycin were included. The primary outcome was composite failure: MRSA bacteremia >= 7 days or 30-day all-cause mortality. RESULTS: A total of 191 patients were included; 47.6% IE and 52.4% pneumonia. About 19% were hVISA isolates, median vancomycin PAP MIC of 3 (2, 3). More than half (54.5%) experienced composite failure with a larger proportion of PAP MIC >= 4 mg/L in this group (25 vs. 15%, p = 0.086). Patients with IE experienced prolonged bacteremia whereas patients with pneumonia experienced higher 30-day mortality. On logistic regression analysis, age [adjusted odds ratio (aOR), 1.026; 95% confidence interval (CI), 1.005-1.047; p = 0.014] and APACHE II score (aOR 1.039; 95% CI, 1.004-1.076; p = 0.029) independently predicted composite failure. CONCLUSION: Vancomycin PAP MIC may be a more relevant predictor of patient outcomes in persistent bacteremic MRSA infections (e.g., IE). This susceptibility method is less applicable in other high inoculum infections with shorter bacteremia durations and higher mortality rates (e.g., pneumonia). PMID- 29470837 TI - Past, Present and Future Approaches to the Prevention and Treatment of Respiratory Syncytial Virus Infection in Children. AB - INTRODUCTION: The REGAL (RSV Evidence - A Geographical Archive of the Literature) series has provided a comprehensive review of the published evidence in the field of respiratory syncytial virus (RSV) in Western countries over the last 20 years. This seventh and final publication covers the past, present and future approaches to the prevention and treatment of RSV infection among infants and children. METHODS: A systematic review was undertaken of publications between January 1, 1995 and December 31, 2017 across PubMed, Embase and The Cochrane Library. Studies reporting data on the effectiveness and tolerability of prophylactic and therapeutic agents for RSV infection were included. Study quality and strength of evidence (SOE) were graded using recognized criteria. A further nonsystematic search of the published literature and Clinicaltrials.gov on antiviral therapies and RSV vaccines currently in development was also undertaken. RESULTS: The systematic review identified 1441 studies of which 161 were included. Management of RSV remains centered around prophylaxis with the monoclonal antibody palivizumab, which has proven effective in reducing RSV hospitalization (RSVH) in preterm infants < 36 weeks' gestational age (72% reduction), children with bronchopulmonary dysplasia (65% reduction), and infants with hemodynamically significant congenital heart disease (53% reduction) (high SOE). Palivizumab has also shown to be effective in reducing recurrent wheezing following RSVH (high SOE). Treatment of RSV with ribavirin has conflicting success (moderate SOE). Antibodies with increased potency and extended half-life are currently entering phase 3 trials. There are approximately 15 RSV vaccines in clinical development targeting the infant directly or indirectly via the mother. CONCLUSION: Palivizumab remains the only product licensed for RSV prophylaxis, and only available for high-risk infants. For the general population, there are several promising vaccines and monoclonal antibodies in various stages of clinical development, with the aim to significantly reduce the global healthcare impact of this common viral infection.

AB - BACKGROUND: Colorectal carcinomas (CRCs) are sensitive to treatment by anti epidermal growth factor receptor (EGFR) antibodies only if they do not carry activating mutations in down-stream EGFR targets (KRAS/NRAS/BRAF). Most clinical trials for chemo-naive CRC patients involved combination of targeted agents and chemotherapy, while single-agent cetuximab or panitumumab studies included either heavily pretreated patients or subjects who were not selected on the basis of molecular tests. We hypothesized that anti-EGFR therapy would have significant efficacy in chemo-naive patients with KRAS/NRAS/BRAF mutation-negative CRC. METHODS: Nineteen patients were prospectively included in the study. RESULTS: Two (11%) patients experienced partial response (PR) and 11 (58%) subjects showed stable disease (SD). Median time to progression approached 6.1 months (range 1.6 15.0 months). Cetuximab efficacy did not correlate with RNA expression of EGFR and insulin-like growth factor 2 (IGF2). Only one tumor carried PIK3CA mutation, and this CRC responded to cetuximab. Exome analysis of patients with progressive disease (PD) revealed 1 CRC with high-level microsatellite instability and 1 instance of HER2 oncogene amplification; 3 of 4 remaining patients with PD had allergic reactions to cetuximab, while none of the subjects with PR or SD had this complication. Comparison with 19 retrospective KRAS/NRAS/BRAF mutation negative patients receiving first-line fluoropyrimidines revealed no advantages or disadvantages of cetuximab therapy. CONCLUSIONS: Cetuximab demonstrates only modest efficacy when given as a first-line monotherapy to KRAS/NRAS/BRAF mutation negative CRC patients. It is of question, why meticulous patient selection, which was undertaken in the current study, did not result in the improvement of outcomes of single-agent cetuximab treatment.

AB - The development and utilization of biomass resources could contribute to new materials for long-term sustainable energy storage and environmental applications, reduce environmental impacts, and meet the urgent need for green and sustainable development strategies. Herein, a bimetallic metal-phenolic network (MPN) was applied to incorporate different metallic element species into cattle skin and fabricate collagen-fiber-derived complex oxide nanofibers using natural polyphenols (Myrica tannins). Direct thermal transition of these biomass MPN composites generates hierarchically porous nanofibers possessing micro- and mesoporous architectures along with a well-preserved macroscopic structure. The pore system and complex oxide composition provide excellent photocatalytic performance. This low-cost, simple, and readily scalable MPN-based approach provides a straightforward route to synthesize nanostructured materials directly from biomass, which could play important roles in a wide range of potential applications. PMID- 29470839 TI - Embryonic neurogenesis in echinoderms. AB - The phylogenetic position of echinoderms is well suited to revealing shared features of deuterostomes that distinguish them from other bilaterians. Although echinoderm neurobiology remains understudied, genomic resources, molecular methods, and systems approaches have enabled progress in understanding mechanisms of embryonic neurogenesis. Even though the morphology of echinoderm larvae is diverse, larval nervous systems, which arise during gastrulation, have numerous similarities in their organization. Diverse neural subtypes and specialized sensory neurons have been identified and details of neuroanatomy using neuron specific labels provide hypotheses for neural function. The early patterning of ectoderm and specification of axes has been well studied in several species and underlying gene regulatory networks have been established. The cells giving rise to central and peripheral neural components have been identified in urchins and sea stars. Neurogenesis includes typical metazoan features of asymmetric division of neural progenitors and in some cases limited proliferation of neural precursors. Delta/Notch signaling has been identified as having critical roles in regulating neural patterning and differentiation. Several transcription factors functioning in pro-neural phases of specification, neural differentiation, and sub-type specification have been identified and structural or functional components of neurons are used as differentiation markers. Several methods for altering expression in embryos have revealed aspects of a regulatory hierarchy of transcription factors in neurogenesis. Interfacing neurogenic gene regulatory networks to the networks regulating ectodermal domains and identifying the spatial and temporal inputs that pattern the larval nervous system is a major challenge that will contribute substantially to our understanding of the evolution of metazoan nervous systems.

PMID- 29470841 TI - Disease Duration and Stage Influence Bone Microstructure in Patients With Primary Biliary Cholangitis. AB - Primary biliary cholangitis (PBC) is known to be a major risk factor for osteoporosis reflected by a reduction of bone mineral density (BMD). However, both the extent of the macro- and microstructural alterations of bone as well as the causative factors are unknown. We have retrospectively analyzed a total of 96 patients with PBC and 53 healthy controls matched for age, sex, and body mass index. In addition to dual-energy X-ray absorptiometry (DXA) measurements at the lumbar spine and hip, high-resolution peripheral quantitative computed tomography (HR-pQCT) was used to assess the geometric, volumetric, and microstructural changes of bone at the distal radius and tibia. Furthermore, serum analyses and measures of disease duration and stage including transient elastography were performed. Total, cortical, and trabecular volumetric BMD as well as geometric parameters were significantly reduced in PBC patients. Microstructural analysis revealed a significantly lower cortical thickness (p < 0.001) and bone volume per tissue volume (p < 0.001) in the radius and tibia but unchanged trabecular number in patients with PBC (radius: p = 0.42; tibia: p = 0.12). Multivariate regression models pointed out that disease duration and stage are the primary factors that are independently associated with bone loss in PBC. A subgroup analysis of patients with additional autoimmune hepatitis (AIH) revealed no significant changes in bone structure compared with PBC only. Taken together, PBC patients demonstrate severe alterations in bone microstructure that are positively associated with disease duration and stage. By applying HR-pQCT in the distal radius and tibia, a combined bone loss syndrome expressed by a predominant decrease in BMD and cortical thickness could be detected.

AB - We report the light-induced electronic and geometric changes taking place within a heteroleptic CuI photosensitizer, namely [(xant)Cu(Me2 phenPh2 )]PF6 (xant=xantphos, Me2 phenPh2 =bathocuproine), by time-resolved X-ray absorption spectroscopy in the ps-MUs time regime. Time-resolved X-ray absorption near edge structure (XANES) and extended X-ray absorption fine structure (EXAFS) analysis enabled the elucidation of the electronic and structural configuration of the copper center in the excited state as well as its decay dynamics in different solvent conditions with and without triethylamine acting as a sacrificial electron donor. A three-fold decrease in the decay lifetime of the excited state is observed in the presence of triethylamine, showing the feasibility of the reductive quenching pathway in the latter case. A prominent pre-edge feature is observed in the XANES spectrum of the excited state upon metal to charge ligand transfer transition, showing an increased hybridization of the 3d states with the ligand p orbitals in the tetrahedron around the Cu center. EXAFS and density functional theory illustrate a significant shortening of the Cu-N and an elongation of the Cu-P bonds together with a decrease in the torsional angle between the xantphos and bathocuproine ligand. This study provides mechanistic time-resolved understanding for the development of improved heteroleptic CuI photosensitizers, which can be used for the light-driven production of hydrogen from water.

AB - Low cost, non-noble metal catalysts with a good oxygen reduction reaction (ORR) activity comparable to that of platinum and also having good energy storage properties are highly desirable but challenging. Several challenges are associated with the development of such materials. Herein, we demonstrate a new polycarboxyl-functionalised FeIII -based gel material, synthesised following a solvothermal method and the development of its composite (Fe3 O4 /Fe/C) by annealing at optimised temperature. The developed composite displayed excellent electrocatalytic activity for the oxygen reduction reaction with an onset potential of 0.87 V (vs. RHE) and a current density value of -5 mA cm-2 , which are comparable with commercial 20 wt % Pt/C. In addition, as one of the most desirable properties, the composite exhibits a better methanol tolerance and greater durability than Pt/C. The same material was explored as an energy storage material for supercapacitors, which showed a specific capacitance of 245 F g-1 at a current density of 1 A g-1 . It is expected that this Fe3 O4 /Fe/C composite with a disordered graphitised carbon matrix will pave a horizon for developing energy conversion and energy storage devices.

AB - INTRODUCTION: The forced oscillation technique (FOT) is a particularly useful test of the mechanical properties of the respiratory system that has an increasingly important role in lung function laboratories. There is general agreement in the literature that the determination of reference values is of utmost importance in the clinical use of the FOT. OBJECTIVE: Our aim was to present reference values for whole-breath FOT measurements, establish which anthropometric variables were more predictive of impedance parameters, and provide all the details to adequately adopt these reference equations in individual laboratories. METHODS: We prospectively evaluated a randomly selected non-smoking sample of the adult Brazilian population (288 subjects, 144 males and 144 females aged 20-86 years). The volunteers were separated by sex and divided into six groups based on decade of age. Sex-specific linear prediction equations were developed by multiple regression analysis using age, body mass and height as explanatory variables. RESULTS: Age introduced a slight, but significant, reduction of resistance in men (P < .001) and women (P < .001). In general, significantly higher values of resistance were observed in females (P < .0001). Among the anthropometric variables analyzed, height was the best predictor for all parameters studied. CONCLUSION: This study provides an original frame of reference for the FOT in Brazilian males and females aged 20-86 years. Height was the best predictor of respiratory impedance parameters. Details contributing to an adequate adoption of these reference equations elsewhere by transference and verification are also provided. PMID- 29470845 TI - Electron cryotomography of Mycoplasma pneumoniae mutants correlates terminal organelle architectural features and function. AB - The Mycoplasma pneumoniae terminal organelle functions in adherence and gliding motility and is comprised of at least eleven substructures. We used electron cryotomography to correlate impaired gliding and adherence function with changes in architecture in diverse terminal organelle mutants. All eleven substructures were accounted for in the prkC, prpC and P200 mutants, and variably so for the HMW3 mutant. Conversely, no terminal organelle substructures were evident in HMW1 and HMW2 mutants. The P41 mutant exhibits a terminal organelle detachment phenotype and lacked the bowl element normally present at the terminal organelle base. Complementation restored this substructure, establishing P41 as either a component of the bowl element or required for its assembly or stability, and that this bowl element is essential to anchor the terminal organelle but not for leverage in gliding. Mutants II-3, III-4 and topJ exhibited a visibly lower density of protein knobs on the terminal organelle surface. Mutants II-3 and III 4 lack accessory proteins required for a functional adhesin complex, while the topJ mutant lacks a DnaJ-like co-chaperone essential for its assembly. Taken together, these observations expand our understanding of the roles of certain terminal organelle proteins in the architecture and function of this complex structure.

AB - Gatekeeper training is a common approach for aiding suicidal youth. This study utilizes comparative effectiveness "benchmarks" from established programs to evaluate the Question, Persuade, Refer (QPR) program. The QPR program was implemented with adults (N = 2,389) working in youth-serving community agencies. Questionnaires assessed suicide prevention knowledge, attitudes, subjective norms, perceived behavioral control, and behaviors. Consistent with benchmarked studies, participants in QPR demonstrated knowledge and suicide prevention behavior gains compared with control groups. Future research should utilize benchmarking methods as a measure of effectiveness, and more thoroughly assess mechanisms that promote behavior change. PMID- 29470847 TI - Cryo-electron tomography analyses of terminal organelle mutants suggest the motility mechanism of Mycoplasma genitalium. AB - The terminal organelle of Mycoplasma genitalium is responsible for bacterial adhesion, motility and pathogenicity. Localized at the cell tip, it comprises an electron-dense core that is anchored to the cell membrane at its distal end and to the cytoplasm at its proximal end. The surface of the terminal organelle is also covered with adhesion proteins. We performed cellular cryoelectron tomography on deletion mutants of eleven proteins that are implicated in building the terminal organelle, to systematically analyze the ultrastructural effects. These data were correlated with microcinematographies, from which the motility patterns can be quantitatively assessed. We visualized diverse phenotypes, ranging from mild to severe cell adhesion, motility and segregation defects. Based on our observations, we propose a double-spring ratchet model for the motility mechanism that explains our current and previous observations. Our model, which expands and integrates the previously suggested inchworm model, allocates specific functions to each of the essential components of this unique bacterial motility system.

AB - A simple and sensitive liquid chromatography tandem mass spectrometry method was validated for simultaneous quantification of evodiamine and its metabolites 10 hydroxyevodiamine (M1), 18-hydroxyevodiamine (M2), 10-hydroxyevodiamine glucuronide (M3) and 18-hydroxy- evodiamine-glucuronide (M4) in rat plasma for the first time. The analytes were extracted with acetonitrile and separated on a C18 column within 3 min. The detection was achieved in positive selected reaction monitoring mode with precursor-to-product transitions at m/z 304.1 -> 161.1 for evodiamine, m/z 320.1 -> 134.1 for M1, m/z 320.1 -> 150.1 for M2, m/z 496.2 -> 134.1 for M3, m/z 496.2 -> 171.1 for M4 and m/z 349.2 -> 305.1 for camptothecin (internal standard). The linearity was evident over the tested concentration ranges with correlation coefficients >0.9991. The lower limits of quantification for evodiamine, M1, M2, M3 and M4 were 0.1, 0.1, 0.1, 0.25 and 0.25 ng mL-1 , respectively. Extraction recoveries and matrix effects of the analytes were within the ranges of 84.51-97.21 and 90.13-103.30%, respectively. The accuracy (relative error) ranged from -8.14 to 7.23% while the intra- and inter-day precisions (relative standard deviation) were < 9.31%. The validated assay was successfully applied for the pharmacokinetic study of evodiamine, M1, M2, M3 and M4 in rat. The current study will be helpful in understanding the in vivo disposition of evodiamine.

AB - Hybrid nanomaterials made of inorganic nanocomponents dispersed in an organic host raise an increasing interest as low-cost solution-processable functional materials. However, preventing phase segregation while allowing a high inorganic doping content remains a major challenge, and usual methods require a functionalization step prior integration. Herein, we report a new approach to design such nanocomposite in which ceramic-like metallic nanocluster compounds are embedded at 10 wt % in organic copolymers, without any functionalization. Dispersion homogeneity and stability are ensured by weak interactions occurring between the copolymer lateral chains and the nanocluster compound. Hybrids could be ink-jet printed and casted on a blue LED. This proof-of-concept device emits in the red-NIR area and generates singlet oxygen, O2 (1 Deltag), of particular interest for lights, display, sensors or photodynamic based therapy applications.

AB - AIMS: Insulin-like growth factor 1 receptor (IGF1R) is involved in cell growth and glucose homeostasis. In the current study, the IGF1R locus was analysed as a candidate gene for type 2 diabetes (T2D) in American Indians. MATERIALS AND METHODS: Whole genome sequence data from 335 American Indians identified 3 novel missense variants in IGF1R. The associations of IGF1R variants with T2D, age of T2D onset and birth weight were analysed in a population-based sample of 7701 American Indians. RESULTS: A novel glycine-to-aspartic acid substitution (G310D) in IGF1R was identified, which associated with T2D in a sex-specific manner (Psex interaction = 0.02). In women, the aspartic acid (D) allele (frequency = 0.034) was associated with increased risk for T2D (n = 4292, P = 2.0 * 10-5 adjusted for age, birth year, and the first 5 genetic principal components; odds ratio [OR] = 2.23 [1.54-3.23] per risk allele) and an earlier age of T2D onset (n = 4292, P = 2 * 10-4 , hazard rate ratio = 1.45 [1.20-1.75], Psex interaction = 0.05). Female carriers of the D-allele also had lower birth weight (n = 1313, beta = -163 g, P = .006, Psex interaction = 0.008). Among 85 siblings discordant for G310D, carriers of the D-allele had shorter stature as compared with carriers of the G allele (beta = -1.6 cm, P = .001, within family model). The G310D variant was functionally studied in vitro, where the D-allele had a 22% increase (P = .0005) in FOXO1-induced transcriptional activity, due to decreased activation of the PI3K/AKT pathway mediated through reduced IGF1R activity. CONCLUSION: A unique G310D variant in IGF1R, which occurs in 6% American Indians, may impair IGF1R signalling pathways, thereby increasing the risk of T2D. PMID- 29470851 TI - The Relation between Descriptive Norms, Suicide Ideation, and Suicide Attempts among Adolescents. AB - This study examined the relationship between adolescents' beliefs about the prevalence of youth suicide ideation (ideation descriptive norms) and suicide attempts (attempt descriptive norms) with self-reported suicide ideation and attempts. Descriptive norms, suicide ideation, and suicide attempts as well as gender, race/ethnicity, and exposure to family, peer, and others' suicide were assessed in 2,109 students at six suburban New York State high schools. After controlling for demographic variables and exposure to suicide, elevated ideation descriptive norms and attempt descriptive norms were associated with higher rates of suicide ideation and lifetime suicide attempts among adolescents. Adolescents who believed suicide ideation and attempts to be more widespread among peers (i.e., elevated ideation and attempt descriptive norms) were more likely to endorse suicide ideation and attempts. Correcting these descriptive norms may be a worthwhile goal for school-based suicide prevention programs.

AB - Sperm RNA is a sensitive monitoring endpoint for male reproductive toxicants, and a potential biomarker to assess male infertility and sperm quality. However, isolation of sperm RNA is a challenging procedure due to the heterogeneous population of cells present in the ejaculate, the low yield of RNA per spermatozoon, and the absence of 18S and 28S ribosomal RNA subunits. The unique biology of spermatozoa has created some uncertainty in the field about RNA isolation methods, indicating the need for rigorous quality control checks to ensure reproducibility of data generated from sperm RNA. Therefore, we developed a reliable and effective protocol for RNA isolation from rat and human spermatozoa that delivers highly purified and intact RNA, verified using RNA specific electrophoretic chips and molecular biology approaches such as RT-PCR and Western blot analysis. The sperm RNA isolation technique was optimized using rat spermatozoa and then adapted to human spermatozoa. Three steps in the sperm isolation procedure, epididymal fluid collection, sperm purification, and spermatozoon RNA extraction, were evaluated and assessed. The sperm RNA extraction methodology consists of collection of rat epididymal fluid with repeated needle punctures of the epididymis, somatic cell elimination using detergent-based somatic cell lysis buffer (SCLB) and the use of RNA isolation Kit. Rat sperm heads are more resistant to disruption than human spermatozoa, necessitating the addition of mechanical lysis with microbeads and heat in the rat protocol, whereas the human sperm protocol only required lysis buffer. In conclusion, this methodology results in reliable and consistent isolation of high quality sperm RNA. Using this technique will aid in translation of data collected from animal models, and reproducibility of clinical assessment of male factor fertility using RNA molecular biomarkers. PMID- 29470854 TI - The Cost-Effectiveness of Screening in the Community to Reduce Osteoporotic Fractures in Older Women in the UK: Economic Evaluation of the SCOOP Study. AB - The SCOOP study was a two-arm randomized controlled trial conducted in the UK in 12,483 eligible women aged 70 to 85 years. It compared a screening program using the FRAX(r) risk assessment tool in addition to bone mineral density (BMD) measures versus usual management. The SCOOP study found a reduction in the incidence of hip fractures in the screening arm, but there was no evidence of a reduction in the incidence of all osteoporosis-related fractures. To make decisions about whether to implement any screening program, we should also consider whether the program is likely to be a good use of health care resources, ie, is it cost-effective? The cost per gained quality adjusted life year of screening for fracture risk has not previously been demonstrated in an economic evaluation alongside a clinical trial. We conducted a "within trial" economic analysis alongside the SCOOP study from the perspective of a national health payer, the UK National Health Service (NHS). The main outcome measure in the economic analysis was the cost per quality adjusted life year (QALY) gained over a 5-year time period. We also estimated cost per osteoporosis-related fracture prevented and the cost per hip fracture prevented. The screening arm had an average incremental QALY gain of 0.0237 (95% confidence interval -0.0034 to 0.0508) for the 5-year follow-up. The incremental cost per QALY gained was L2772 compared with the control arm. Cost-effectiveness acceptability curves indicated a 93% probability of the intervention being cost-effective at values of a QALY greater than L20,000. The intervention arm prevented fractures at a cost of L4478 and L7694 per fracture for osteoporosis-related and hip fractures, respectively. The current study demonstrates that a systematic, community-based screening program of fracture risk in older women in the UK represents a highly cost effective intervention. (c) 2018 The Authors.

AB - Single-component conductors based on neutral organic radicals have received a lot of attention due to the possibility that the unpaired electron can serve as a charge carrier without the need of a previous doping process. Although most of these systems are based on delocalized planar radicals, we present here a nonplanar and spin localized radical based on a tetrathiafulvalene (TTF) moiety, linked to a perchlorotriphenylmethyl (PTM) radical by a conjugated bridge, which exhibits a semiconducting behavior upon application of high pressure. The synthesis, electronic properties, and crystal structure of this neutral radical TTF-Ph-PTM derivative (1) are reported and implications of its crystalline structure on its electrical properties are discussed. On the other hand, the non radical derivative (2), which is isostructural with the radical 1, shows an insulating behavior at all measured pressures. The different electronic structures of these two isostructural systems have a direct influence on the conducting properties, as demonstrated by band structure DFT calculations.

AB - Hepcidin mediated ferroportin (Fpn) degradation in macrophages is a well adopted strategy to limit iron availability towards invading pathogens. Leishmania donovani (LD), a protozoan parasite, resides within macrophage and competes with host for availing iron. Using in vitro and in vivo model of infection, we reveal that LD decreases Fpn abundance in host macrophages by hepcidin independent mechanism. Unaffected level of Fpn-FLAG in LD infected J774 macrophage confirms that Fpn down-regulation is not due its degradation. While increased Fpn mRNA but decreased protein expression in macrophages suggests blocking of Fpn translation by LD infection that is confirmed by 35 S-methionine labelling assay. We further reveal that LD blocks Fpn translation by induced binding of iron regulatory proteins (IRPs) to the iron responsive element present in its 5'UTR. Supershift analysis provides evidence of involvement of IRP2 particularly during in vivo infection. Accordingly, a significant increase in IRP2 protein expression with simultaneous decrease in its stability regulator F-box and leucine-rich repeat Protein 5 (FBXL5) is detected in splenocytes of LD-infected mice. Increased intracellular growth due to compromised expressions of Fpn and FBXL5 by specific siRNAs reveals that LD uses a novel strategy of manipulating IRP2-FBXL5 axis to inhibit host Fpn expression.

AB - The definition of a suitable mesh to simulate blood flow in the human carotid bifurcation has been investigated. In this research, a novel mesh generation method is proposed: hexahedral cells at the center of the vessel and a fine grid of tetrahedral cells near the artery wall, in order to correctly simulate the large blood velocity gradients associated with specific locations. The selected numerical examples to show the pertinence of the novel generation method are supported by carotid ultrasound image data of a patient-specific case. Doppler systolic blood velocities measured during ultrasound examination are compared with simulated velocities using 4 different combinations of hexahedral and tetrahedral meshes and different fluid dynamic simulators. The Lin's test was applied to show the concordance of the results. Wall shear stress-based descriptors and localized normalized helicity descriptor emphasize the performance of the new method. Another feature is the reduced computation time required by the developed methodology. With the accurate combined mesh, different flow rate partitions, between the internal carotid artery and external carotid artery, were studied. The overall effect of the partitions is mainly in the blood flow patterns and in the hot-spot modulation of atherosclerosis-susceptible regions, rather than in their distribution along the bifurcation. PMID- 29470859 TI - Added value of second biopsy target in screen-detected widespread suspicious breast calcifications. AB - INTRODUCTION: There is controversy on the optimal work-up of screen-detected widespread breast calcifications: whether to biopsy a single target or multiple targets. This study evaluates agreement between multiple biopsy targets within the same screen-detected widespread (>=25 mm) breast calcification to determine if the second biopsy adds value. METHODS: Retrospective observational study of women screened in a statewide general population risk breast cancer mammographic screening program from 2009 to 2016. Screening episodes recalled for widespread calcifications where further views indicated biopsy, and two or more separate target areas were sampled within the same lesion were included. Percentage agreement and Cohen's Kappa were calculated. RESULTS: A total of 293317 women were screened during 761124 separate episodes with recalls for widespread calcifications in 2355 episodes. In 171 women, a second target was biopsied within the same lesion. In 149 (86%) cases, the second target biopsy result agreed with the first biopsy (kappa = 0.6768). Agreement increased with increasing mammography score (85%, 86% and 92% for score 3, 4 and 5 lesions). Same day multiple biopsied lesions were three times more likely to yield concordant results compared to post-hoc second target biopsy cases. CONCLUSION: While a single target biopsy is sufficient to discriminate a benign vs. malignant diagnosis in most cases, in 14% there is added value in performing a second target biopsy. Biopsies performed prospectively are more likely to yield concordant results compared to post-hoc second target biopsy cases, suggesting a single prospective biopsy may be sufficient when results are radiological pathological concordant; discordance still requires repeat sampling. PMID- 29470858 TI - Genes affecting progression of bacteriophage P22 infection in Salmonella identified by transposon and single gene deletion screens. AB - Bacteriophages rely on their hosts for replication, and many host genes critically determine either viral progeny production or host success via phage resistance. A random insertion transposon library of 240,000 mutants in Salmonella enterica serovar Typhimurium was used to monitor effects of individual bacterial gene disruptions on bacteriophage P22 lytic infection. These experiments revealed candidate host genes that alter the timing of phage P22 propagation. Using a False Discovery Rate of < 0.1, mutations in 235 host genes either blocked or delayed progression of P22 lytic infection, including many genes for which this role was previously unknown. Mutations in 77 genes reduced the survival time of host DNA after infection, including mutations in genes for enterobacterial common antigen (ECA) synthesis and osmoregulated periplasmic glucan (OPG). We also screened over 2000 Salmonella single gene deletion mutants to identify genes that impacted either plaque formation or culture growth rates. The gene encoding the periplasmic membrane protein YajC was newly found to be essential for P22 infection. Targeted mutagenesis of yajC shows that an essentially full-length protein is required for function, and potassium efflux measurements demonstrated that YajC is critical for phage DNA ejection across the cytoplasmic membrane.

AB - Harpagoside, an iridoid glycoside, is the major bioactive constituent of the traditional Chinese medicine Scrophulariae Radix. High-performance liquid chromatography with a diode array detector combined with electrospray ionization ion trap time-of-flight multistage mass spectrometry (HPLC-ESI-IT-TOF-MSn ) was used to profile and identify the metabolites of harpagoside in rats in vivo and to study the distribution of these metabolites in rats for the first time. A total of 45 metabolites were identified, 37 of which were postulated to be new compounds. The number of detected metabolites in the heart, liver, spleen, lung, kidney, stomach and small intestine was 2, 9, 6, 16, 4, 16 and 6, respectively, which indicated that the target organs of harpagoside should be spleen, lung and stomach. The main types of metabolic reactions of harpagoside in rats are hydrolysis, reduction, sulfuric acid addition, hydroxylation, methoxylation, sulfate substitution, methylation, glucose conjugation and amino acid conjugation. Furthermore, 23 metabolites were determined to have bioactivities based on the literature and 'PharmMapper' analysis. These findings are useful for better comprehension of the effective forms, target organs and pharmacological effects of harpagoside. Moreover, these findings provide a reference for studying the metabolism and distribution of iridoid compounds. PMID- 29470861 TI - Mini-Cog for the diagnosis of Alzheimer's disease dementia and other dementias within a primary care setting. AB - BACKGROUND: Alzheimer's disease and other forms of dementia are becoming increasingly common with the aging of most populations. The majority of individuals with dementia will first present for care and assessment in primary care settings. There is a need for brief dementia screening instruments that can accurately diagnose dementia in primary care settings. The Mini-Cog is a brief, cognitive screening test that is frequently used to evaluate cognition in older adults in various settings. OBJECTIVES: To determine the diagnostic accuracy of the Mini-Cog for diagnosing Alzheimer's disease dementia and related dementias in a primary care setting. SEARCH METHODS: We searched the Cochrane Dementia and Cognitive Improvement Register of Diagnostic Test Accuracy Studies, MEDLINE, Embase and four other databases, initially to September 2012. Since then, four updates to the search were performed using the same search methods, and the most recent was January 2017. We used citation tracking (using the databases' 'related articles' feature, where available) as an additional search method and contacted authors of eligible studies for unpublished data. SELECTION CRITERIA: We only included studies that evaluated the Mini-Cog as an index test for the diagnosis of Alzheimer's disease dementia or related forms of dementia when compared to a reference standard using validated criteria for dementia. We only included studies that were conducted in primary care populations. DATA COLLECTION AND ANALYSIS: We extracted and described information on the characteristics of the study participants and study setting. Using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) criteria we evaluated the quality of studies, and we assessed risk of bias and applicability of each study for each domain in QUADAS 2. Two review authors independently extracted information on the true positives, true negatives, false positives, and false negatives and entered the data into Review Manager 5 (RevMan 5). We then used RevMan 5 to determine the sensitivity, specificity, and 95% confidence intervals. We summarized the sensitivity and specificity of the Mini-Cog in the individual studies in forest plots and also plotted them in a receiver operating characteristic plot. We also created a 'Risk of bias' and applicability concerns graph to summarize information related to the quality of included studies. MAIN RESULTS: There were a total of four studies that met our inclusion criteria, including a total of 1517 total participants. The sensitivity of the Mini-Cog varied between 0.76 to 1.00 in studies while the specificity varied between 0.27 to 0.85. The included studies displayed significant heterogeneity in both methodologies and clinical populations, which did not allow for a meta-analysis to be completed. Only one study (Holsinger 2012) was found to be at low risk of bias on all methodological domains. The results of this study reported that the sensitivity of the Mini-Cog was 0.76 and the specificity was 0.73. We found the quality of all other included studies to be low due to a high risk of bias with methodological limitations primarily in their selection of participants. AUTHORS' CONCLUSIONS: There is a limited number of studies evaluating the accuracy of the Mini-Cog for the diagnosis of dementia in primary care settings. Given the small number of studies, the wide range in estimates of the accuracy of the Mini-Cog, and methodological limitations identified in most of the studies, at the present time there is insufficient evidence to recommend that the Mini-Cog be used as a screening test for dementia in primary care. Further studies are required to determine the accuracy of Mini Cog in primary care and whether this tool has sufficient diagnostic test accuracy to be useful as a screening test in this setting.

AB - Sedentary plant-parasitic cyst nematodes are obligate biotrophs that infect the roots of their host plant. Their parasitism is based on the modification of root cells to form a hypermetabolic syncytium from which the nematodes draw their nutrients. The aim of this study was to identify nematode susceptibility genes in Arabidopsis thaliana and to characterize their roles in supporting the parasitism of Heterodera schachtii. By selecting genes that were most strongly upregulated in response to cyst nematode infection, we identified HIPP27 (HEAVY METAL ASSOCIATED ISOPRENYLATED PLANT PROTEIN 27) as a host susceptibility factor required for beet cyst nematode infection and development. Detailed expression analysis revealed that HIPP27 is a cytoplasmic protein and that HIPP27 is strongly expressed in leaves, young roots and nematode-induced syncytia. Loss-of function Arabidopsis hipp27 mutants exhibited severely reduced susceptibility to H. schachtii and abnormal starch accumulation in syncytial and peridermal plastids. Our results suggest that HIPP27 is a susceptibility gene in Arabidopsis whose loss of function reduces plant susceptibility to cyst nematode infection without increasing the susceptibility to other pathogens or negatively affecting the plant phenotype. PMID- 29470863 TI - The evolution of mollusc shells. AB - Molluscan shells are externally fabricated by specialized epithelial cells on the dorsal mantle. Although a conserved set of regulatory genes appears to underlie specification of mantle progenitor cells, the genes that contribute to the formation of the mature shell are incredibly diverse. Recent comparative analyses of mantle transcriptomes and shell proteomes of gastropods and bivalves are consistent with shell diversity being underpinned by a rapidly evolving mantle secretome (suite of genes expressed in the mantle that encode secreted proteins) that is the product of (a) high rates of gene co-option into and loss from the mantle gene regulatory network, and (b) the rapid evolution of coding sequences, particular those encoding repetitive low complexity domains. Outside a few conserved genes, such as carbonic anhydrase, a so-called "biomineralization toolkit" has yet to be discovered. Despite this, a common suite of protein domains, which are often associated with the extracellular matrix and immunity, appear to have been independently and often uniquely co-opted into the mantle secretomes of different species. The evolvability of the mantle secretome provides a molecular explanation for the evolution and diversity of molluscan shells. These genomic processes are likely to underlie the evolution of other animal biominerals, including coral and echinoderm skeletons.

MATERIALS AND METHODS: The study was retrospective and was conducted in the Department of General Oncology and Gynecology, MMA for the period from 2014 to 2016 years. Included are 25 non pregnant premenopausal women aged 29 to 45 years with clinical symptoms. The main inclusion criteria were delivery by CS, overt clinical gynecological symptoms and positive imaging findings of a defect in the scar. The main gynecological symptoms are: postmenstrual and breakthrough bleeding, dysmenorrhea, dispaureny and idiopathic pain over the symphysis. Imaging studies were performed using two dimensional transvaginal sonography and diagnostic hysteroscopy. The data are processed by Social statistic STAT 10. We used Chi square statistic test 12.5 (Pearson). Data were compared to two independent groups. Results were statistically significant at values of p<0. 05. RESULTS: The most common symptom in women included in the study was a post-menstrual bleeding - 22 (88 %). In 15 (60 %) of them we found out ultrasound signs of a defect in uterine scar (p =0, 00407). In 10 (40%) of those patients by diagnostic hysteroscopy we found defective scar (p=0, 000004). There has been no significant difference between the two methods in terms of accuracy of diagnosis (isthmocele) (p=0.1572) although the hysteroscopy there was a statistically higher one. CONCLUSION: With increasing frequency of cesarean section (CS) increases and frequency of early and late complications of this surgery. Irregular uterine bleeding in women after CS and a lack of other organic causes are the result of a defect in uterine scar. First choice for the diagnosis of this type of pathology is ultrasonography examination followed by diagnostic hysteroscopy. It is conducting further studies on the etiology of this complication.

Children born prematurely are at increased risk of death, major neonatal complications, long term adverse consequences for health and development. The cause of spontaneous preterm birth is often unknown, but it is believed that intrauterine infection is implicated in 40% of cases. The most likely route to intrauterine infection is ascending infection of the genital tract. Infection of the genital tract is more common in women with spontaneous preterm births in lower ge. tational age. s performed a retrospective research of 70 pregnant women and their newborns. In the group with preterm birth was reported high percentage of CVI - 37.14%, while in the control group this percentage is 17.14%. The results showed the increase in the incidence of CVI group of PB more than twice. There is a need an effective prevention and treatment of CVI during pregnancy. The timely detection of deviations from normal vaginal microflora and the correct therapeutic approach would reduce the risks of PB and infectious complications in newborns.

The tests in themselves (cardiotocography (NST), sonography, Doppler studies) which are used for antenatal fetus surveillance are aimed at timely diagnosing the signs of the fetus asphyxia. The objective of the current research is to study which modifications in the cardiotocography (NST), arterial and venosus Doppler correlate most strongly with severe asphyxia pH< 7.10 and BE>=12 mmol/l regarding pregnancies which are complicated with intrauterine growth restriction of the fetus. The presence of spontaneous decelerations in the cardiotocography shows sensitivity 81.3%, specificity 97.1%, positive predictive value (PPV) 83.2, negative predictive value (NPV) 98.2%, odds ratio (OR) 260, p< 0.0001, the reversed blood velocity of artery umbilicalis shows sensitivity 58.3%, specificity 96.2%, PPV 63.6%, NPV 95. 3% OR 35.7 p< 0.001, reversed a-wave ductus venosus shows sensitivity 51%, specificity 94.3%, PPV 48% NPV 93.2% OR 16.7, p< 0.001. Concerning pregnant women with intrauterine growth restriction of the fetus the prognostication of severe fetus asphyxia at delivery - pH<7. 10 and BE 12 mmol/I with the highest specificity of antenatal testing is the occurrence of spontaneous decelerations in NST, the reversed blood velocity of umbilical artery and the reversed a-wave ductus venosus in Doppler studies.

OBJECTIVE: The study shows the results of a cost-effectiveness evaluation based on two alternative mechanisms: annual faecal immunochemical testing (FIT), and colonoscopy every ten years in Argentina. METHODS: The study develops a Mar- kov model in ten stages, based on information provided by the INC, prior literature review and on-line questionnaires to physicians enrolled in the four major scientific societies related to cancer. Cost information arrived from the Na- tional Superintendence of Social Health Insurances and a sample of managers in social and private insurance schemes. RESULTS: The most cost-effective strategy consisted annual FIT, in comparison no intervention and colonoscopy every 10 years. The incremental cost effectiveness ratio (ICER) of FIT versus no intervention was of 980.5 pesos per QALY The findings were robust to deterministic sensitivity analysis. CONCLUSIONS: We confirmed that screening for CRC is a cost-effective intervention. Whereas the CCR is one of the leading causes of mortality in Argentina, these results support the widespread use of screening for CRC using anual FIT which proves to be highly cost effective for the country.

Screening for colorectal cancer in asymptomatic patients is crucialfor reducing the incidence and colonoscopy is one of the methods of choice. The ability of colonoscopy in detecting small lesions is clearly influenced by the quality of the colonic preparation. OBJECTIVES: To know which are the variablesrelating to the patient and the type ofpreparation that affect the quality of colonic cleansing. MATERIALS AND METHODS: It was designed a cross sectional study. It was administered a questionnaire for the enrolled subjects to assess the presence offactors that could affect the quality of colonic cleansing. Then they underwent a colonoscopy. The different variables between subjects with adequate or inadequate colonic cleansing were compared. RESULTS: We evaluated 277 subjects. In multivariate analysis the only variables that showed significant differences are split dose [OR 0.45 (0.21 to 0.99)] and age [OR 1.02 (1-1.05)]. Obesity showed no significant differences in multivariate analysis [OR 1.84 (0.9 3.78)]. CONCLUSIONS: Age and split-dose were the only variables significantly associated with the quality of bowel preparation prior to colonoscopy. Not so constipation or the presence ofdiverticula, so these patients do not require special preparation regimes.

Treatment is reservedfor symptomatic cases. In Argentina, ZD has historically managed exclusively by surgical intervention. In 1995, Ishioka, et al and Mulder, et a1published their experience using flexible endoscopes for diverticulotomy. Since then, a wide variety ofdifferent techniques have been published. Objetive. To present technique modifications and results ofour center. MATERIAL AND METHODS: We reviewed the database of57patients (36 men), with a mean age of 71.9 years (range 37-98), with symptomatic Zenker ' diverticulum, who underwent endoscopic myotomy, from December 1997 to April 2015. All procedures were performed in our center, by the same endoscopist (HM). The most common symptom was dysphagia (94.7%), which was recorded by a 0-4 score (0=no dysphagia, 1 =solids, 2=semisolids, 3=liquids, 4=saliva). The first nine cases were done exposing the septum with a nasogastric tube, and the others with a soft diverticuloscope. Allprocedures were carried out with the patient under deep sedation, adminis- tered by an anesthesiologist. A myotomy was done in all cases with a needle-knife, using a coagulation current, to prevent bleeding. Clips were placed to close mucosalilaps, decrease the risk of unsuspected perforation and postprocedure bleeding. RESULTS: Seventy procedures were performed, in 56 patients. One patient was excluded because of incomplete myotomy due to a severe adverse event. Ninety-eight percent ofpatients had resolution or improvement of the dysphagia score, at 30 days. Three patients with regurgitation as their sole complaint completely resolved their symptom. Median follow-up was 25 months (1 99). Thirty-seven patients were followed for at least 1 year and 97.3% showed a favorable outcome. In 13 cases (22.8%) a reintervention was needed, with positive results in all cases. Bleeding occurred in one patient (1.4%), who required surgery. Another patient required surgical intervention due to technical issues. There were no perforations or infections. CONCLUSION: Treatment of ZD with flexible endoscope is a safe and effective option, with good long-term results. We need randomized clinical trials comparing different therapeutic options to be able to recommend a definitive strategy. Until then, we suggest using the technique with which each center has the most experience and feels most comfortable performing.

We report a case of a 35-year-old male who was admitted to our hospital with a history of abdominal pain, constipation and a palpable mass in the left lower quadrant. Abdominal CT scan showed diffuse thickening of the descending and rectosigmoid colon, associated with increased density of the mesenteric fat. After failure ofan initial treat- ment with glucocorticoids, he underwent a laparoscopic sigmoidectomy. Histopatholog analysis revealed extensive stea- tonecrosis ofpericolonicfat and lipid ladenfoamy cells which was consistent with the diagnosis of mesenteric lipodystrophy. Clinical presentation and treatment as well as a brief review of the literature are discussed.

Working group of the Latinamerican Society of Pediatric Gastroenterology, Hepatology and Nutrition (LASPGHAN).] AB - Pediatric acute liver failure is a syndrome ofsevere and sudden dysfunction of the hepatocytes which produces a failure in synthetic and detoxifyingfunction. It is an infrequent and severe disease butpotentiallyfatal, occurring in children with no prior history of liver disease. Etiology is related to the age and geographic region of the patient, recognizing the origin: metabolic, infectious, drug exposure, autoinmune, vascular and oncologic. Indeterminate cause where all the etiological search is negative, can range between 18 and 47%, depending on the center and access to the realization of etiological studies. The process which determines the liver injury is still not well known and is considered multifactorial. Essentially, it depends on host susceptibility, the cause and severity of the damage and the ability of liver regeneration. The clinical presentation depends on the etiology, which usually begins with an episode ofacute hepatitis, that in the following days or weeks presents unfavorable outcome, deepening jaundice, affecting the general state and presenting severe coagulopathy that characterizes the syndrome. The treatment consists of general measures which take into account the metabolic disorders, nutritional aspect, and the prevention and treatment of all complications that occur in the evolutionary course (infectious, neurological, etc). Besides it is also vital to implement the specific treatment of those diseases which can benefit from it (alloimmune hepatitis, galactosemia, tyrosinemia, herpes simplex infection, Wilson's disease, etc.). However, despite therapeutic advances, acute liver failure results in death or liver transplantation in over 45% ofcases.

MATERIALS AND METHODS: the study included 34 high-risk surgical patients with "critical aortic stenosis". All patients underwent TAVI with femoral access. TAVI performed under local anaesthesia: in 18 cases - with midazolam-ketamine sedetion, in 16 cases - with dexmedetomidine sedation. The depth of sedation was evaluated by Richmond agitation-sedation scale (RASS) and Ramsay scale. Assessment includes frequency of complications arising during perioperative period. RESULTS: in dexmedetomidine group compared with a group of midazolam/ketamine was observed significantly greater median of sedation level with RASS and Ramsay scales (- 3.5 and -1.0, p=0,000004, 5.0 and 3.0, respectively, p=0,000001). There was a signficant decrease in rapid pacing episodes in dexmedetomidine group (p = 0.0005). In the structure of complications prevailed delirium, stroke, ventricularfibrillation. There were no significant differences in the incidence and nature of complications in the groups studied. Under midazolam/ ketamine trend toward increased incidence of delirium compared with a group of dexmedetomidine (6.16 % and 6.25 %, respectively, p =0.604). There was no significant difference in the duration of operation and anesthesia in the study groups (p=0.889, p=0.103). There were no significant differences in length of hospital-stay and in the length of ICU-stay in groups studied (p =0.243, p=0.899). CONCLUSIONS: Sedation with dexmedetomidine during TA VI with femoral access demonstrates its safety and effectiveness. Dexmedetomidine provides deep level of sedation with RASS and Ramsay scales without depression of respiratory function. There is a good tolerability of operation and good conditions for long-term use of transesophageal ECHO. In the context of ECHO monitoring further reduces the need for multiple rapid pacing (p = 0.0005), which may reduce frequency of delirium in elderly patients.

There were developed special protocols for critically ill patients, which helps to obtain the diagnosis at the bedside. Therefore all the world's leading societies and associations recommend to include the training of ultrasound technology in the education program for anesthesiologists and intensive care specialists. Society for Ultrasound in Anaesthesia recommended to acquire six competencies: ultrasound monitoring of the respiratory tract in anesthesiology and critical care medicine; ultrasound monitoring of the pleura and the lungs; focused echocardiography and intraoperative monitoring; catheterization of blood vessels under the control of ultrasound; ultrasound monitoring ofcritically ill patients; ultrasound navigation for regional anesthesia. Resident physician should have skills for ultrasound assistance during catheterization central veins and for ultrasound monitoring in critical ill patients to the extent of FAST protocol (level ofpractical skill "to be able'). Other topics should being studied at the level "to know". It is reasonable to hone practical skills on these competences as part ofpostgraduate continuing education program to the extent that is needed for specialist at his workplace.

Given that the treatment of this pathology and surgery performed only at an early age of the child, the need for transfusion arise very often. THE AIM: To study the efficacy ofpreoperative use of darbepoetin alfa in combination with intraoperative normovolemic hemodilution to reduce the number of blood transfusions during surgery and in the early postoperative period. MATERIALS AND METHODS: The study included 70 children between the ages of 6 months up to 12 months, divided into two groups: a control group (n=34) without stimulation of erythropoiesis and the study group (n =36) using apre-stimulation oferythropoiesis darbepoetin alfa. RESULTS: In the control group, blood transfusion was performed in 79% of cases, compared with the test group-22% of cases. Also, the patients ofthe study group determined a statistically significant (p<0. 05) increase the level of red blood cells, hemoglobin and reticulocytes. CONCLUSION: In children up to a year with various forms ofnon-syndromic craniosynostosis preoperative stimulation of erythropoiesis in conjunction with normovolemic hemodilution reduces the number of blood transfusions 3 times, or to opt out of its holding.

MATERIALS AND METHODS: a retrospective open-controlled clinical research with a resolution of the Ethics;Committee performed in 33 neonates born in asphyxia and treated at the NICU All newborns due to the presence of indications, overall controlled hypothermia was conducted according to the approved protocol, using the apparatus Allon 2001". RESULTS: The neurological status at admission: Sarnat II was detected in 60.6% (20) children; Sarnat III was detected in 39.4% (13) children. The correlation ofApgar scores with the most severe hypoxic ischemic encephalopathy. Pupillary reflexes admission absent in 48.5% (16) newborns. Convulsions within first hours of lfe were observed in 57.6% (19) newborns. Convulsions within I day of life were observed in 81.8 % (27) newborns. The correlation of the amniotic infection (AI) and meconium aspiration syndrome (MAS) treatment using high-frequency mechanical ventilation (p<0,05) and prolongation of mechanical ventilation for more than 5 days (p<0,01). At the beginning of systemic hypothermia fraction of inspired oxygen (FiO2), mean airway pressure (MAP), respiratory rate (RR) were down to the 12th hour of life and reaches a minimum at the end of the third day. These trends have been observed in children with MAS. The correlation of the use of high frequency mechanical ventilation using high doses ofcardiotonics and the transition to the infusion of epinephrine or norepinephrine (p <0.01).There were no deaths in the studying group. CONCLUSIONS: 1. Reliable predictor of the clinical outcomes severity of hypoxic-ischemic encephalopathy (HIE) by the end of the first month lf is the presence of convulsions within the first hour of lf (p<0. 03). 2. When comparing the evaluation on Apgar scale with the data of acid base balance and severity of HIE a significant correlation between the estimation at the first minute is I point and at the fifth minute 3 point and more severe pH shift, base deficiency, hyperlactatacidosis and severe HIE. 3. MAS and AI are the most frequent accompanying diseases that complicates the severity of newborn status causing prolonged artificial ventilation and the infusion ofcardiotonics. 4. There is a decrease in all parameters of artficial lung ventilation to the twelfth hour life in early systemic hypothermia and reached minimum by the end of the third day.

Publications of the results of major studies on the subject have appeared recently. Only the multivariate analysis will make a reasonable conclusion about the causes that affect the outcome and assess the extent of the simultaneous influence on him of often interrelated reasons. THE AIM: To estimate the signficance of obesity as an independent risk factor for serious obstetric haemorrhage. MATERIALS AND METHODS: A retrospective cohort study ofpregnancy and childbirth outcomes of 24634 women in childbirth. Depending on the initial body mass index (BM) of the patients were allocated two groups: basic - 2140 obese women with control - 17937 patients with an initial BW of 18.5 to 24.9 kg / m2. In order to determine the significance of obesity as a riskfactor of massive blood loss midwife performed multivariate statistical analysis, including cluster analysis, multiple correlation, linear and non-linear regression, statistical quality control using control charts. RESULTS: Hypotension uterus has been a major factor in the development of massive blood loss. For the implementation of hypotonic uterine bleeding was necessary set of conditions, interacting with other causal factors affecting the outcome. The minimum combination of these factors is the combination of "obesity" + "somatic pathology" + "induction of labor," in which the OR of postpartum hemorrhage was 8,57 [CI 95% 6,13-36,28], p < 0.001. It is also significant risk factors were fetal macrosomia, multiple pregnancy, abdominal method of delivery, the degree of obesity, the method of anesthesia and duration of the operation. OR to define obesity as an isolated risk factor for the implementation of massive blood loss was 1.18 [95% CI: 0,78-1,27], p > 0.05. DISCUSSION: The impact of obesity as an isolated causes massive obstetric hemorrhage was minimal, but is powerful potentiating factor in the outcome. CONCLUSION: Analysis of the causes of complications in childbirth did not confirm the possibility of considering obesity as an independent risk factor for massive blood loss.

Predict the outcome of injuries - it is an important task of the treating physician. Trauma is a stress factor so to predict the outcome, you can use markers of stress, the most accessible ofwhich is blood glucose. THE AIM: to reveal the dynamics of the relationship between blood glucose levels and the outlook for the life ofpatients with thoracoabdominal injuries. MATERIALS AND METHODS: A retrospective analysis of medical records of hospitalized patients were divided into two groups, depending on the outlook for the life of (favorable or unfavorable), and each of the groups - into two subgroups according to the presence or absence of signs of intoxication at admission. The subgroups were calculated and compared the mean blood glucose levels at different hours of hospital treatment. RESULTS: It was found that the average blood glucose levels at various hours of hospital stay were significantly higher in patients with poor outcome. The most noticeable was the difference in the first days of hospital treatment. Signs of intoxication was associated with lower values of glucose and a tendency to hypoglycaemia. In addition, among patients with high blood glucose ( 8 mg / dL) was observed over deaths in the first day of hospital stay. CONCLUSION: High blood glucose levels ( 8,0 mmol / L) in the first day of hospital treatment is a predictor ofpoor outcome in patients with thoracoabdominal injuries.

Bladder catheterization is a common procedure, which surgical patients are undergone in the perioperative period, and the occurrence of about 80% of all urinary tract infections associated with it. There is no postoperative standard tactics of management patients with the urinary catheter. However, implementation of recommendations for the prevention of the development of CAUTI led to a reduction in the incidence of this type of hospital infections. Aim of our study is to analyse the incidence of catheter associated urinary tract infections in patients undergoing radical prostatectomy, and the establishment of indications for antibiotic therapy in the postoperative period, regarding to the riskfactors. METHODS: The 42 patients undergoing radical prostatectomy combined with pelvic lymphadenectomy were included into the study. The management of perioperative period and the antimicrobial policy was carried out according to the recommendations of IDSA 2009.

AB - A new expanded porphyrin, hexadecaphyrin-(1.0.0.0.1.1.0.1.1.0.0.0.1.1.0.1), is reported. It was obtained via the condensation of a hexapyrrolic derivative prepared in turn from a bipyrrole dialdehyde and a stable quaterpyrrole precursor. This hexadecaphyrin contains eight direct alpha-pyrrole-to-alpha pyrrole linkages in its structure. It supports the formation of bimetallic complexes of both zinc and cobalt that are characterized by different conformational structures. Furthermore, a mixed zinc/cobalt macrocycle has been prepared. The cobalt bimetallic complex shows two stable conformations with the same oxidation state that are in equilibrium. All compounds have been characterized by common spectroscopic means, and single crystal X-ray diffraction structures were obtained for all macrocyclic compounds. DFT calculations and transient absorption spectra were used to study the electronic features of the complexes and the effect of conformational changes. This system shows promise as an accumulated heat sensor. PMID- 29470909 TI - Kernel Tuning and Nonuniform Influence on Optical and Electrochemical Gaps of Bimetal Nanoclusters. AB - Fine tuning nanoparticles with atomic precision is exciting and challenging and is critical for tuning the properties, understanding the structure-property correlation and determining the practical applications of nanoparticles. Some ultrasmall thiolated metal nanoparticles (metal nanoclusters) have been shown to be precisely doped, and even the protecting staple metal atom could be precisely reduced. However, the precise addition or reduction of the kernel atom while the other metal atoms in the nanocluster remain the same has not been successful until now, to the best of our knowledge. Here, by carefully selecting the protecting ligand with adequate steric hindrance, we synthesized a novel nanocluster in which the kernel can be regarded as that formed by the addition of two silver atoms to both ends of the Pt@Ag12 icosohedral kernel of the Ag24Pt(SR)18 (SR: thiolate) nanocluster, as revealed by single crystal X-ray crystallography. Interestingly, compared with the previously reported Ag24Pt(SR)18 nanocluster, the as-obtained novel bimetal nanocluster exhibits a similar absorption but a different electrochemical gap. One possible explanation for this result is that the kernel tuning does not essentially change the electronic structure, but obviously influences the charge on the Pt@Ag12 kernel, as demonstrated by natural population analysis, thus possibly resulting in the large electrochemical gap difference between the two nanoclusters. This work not only provides a novel strategy to tune metal nanoclusters but also reveals that the kernel change does not necessarily alter the optical and electrochemical gaps in a uniform manner, which has important implications for the structure-property correlation of nanoparticles. PMID- 29470910 TI - Fluctuation in Interface and Electronic Structure of Single-Molecule Junctions Investigated by Current versus Bias Voltage Characteristics. AB - Structural and electronic detail at the metal-molecule interface has a significant impact on the charge transport across the molecular junctions, but its precise understanding and control still remain elusive. On the single molecule scale, the metal-molecule interface structures and relevant charge transport properties are subject to fluctuation, which contain the fundamental science of single-molecule transport and implication for manipulability of the transport properties in electronic devices. Here, we present a comprehensive approach to investigate the fluctuation in the metal-molecule interface in single molecule junctions, based on current-voltage ( I- V) measurements in combination with first-principles simulation. Contrary to conventional molecular conductance studies, this I- V approach provides a correlated statistical description of both the degree of electronic coupling across the metal-molecule interface and the molecular orbital energy level. This statistical approach was employed to study fluctuation in single-molecule junctions of 1,4-butanediamine (DAB), pyrazine (PY), 4,4'-bipyridine (BPY), and fullerene (C60). We demonstrate that molecular dependent fluctuation of sigma-, pi-, and pi-plane-type interfaces can be captured by analyzing the molecular orbital (MO) energy level under mechanical perturbation. While the MO level of DAB with the sigma-type interface shows weak distance dependence and fluctuation, the MO level of PY, BPY, and C60 features unique distance dependence and molecular-dependent fluctuation against the mechanical perturbation. The MO level of PY and BPY with the sigma+pi-type interface increases with the increase in the stretch distance. In contrast, the MO level of C60 with the pi-plane-type interface decreases with the increase in the stretching perturbation. This study provides an approach to resolve the structural and electronic fluctuation in the single-molecule junctions and insight into the molecular-dependent fluctuation in the junctions.

AB - Broken symmetry density functional theory has been used to calculate g-tensor, 55Mn, 14N, and 17O hyperfine couplings for active site models of superoxidized MnIII/MnIV manganese catalase both in its native and azide-inhibited form. While a good agreement is found between the calculated and experimental g-tensor and 55Mn hyperfine couplings for all models, the active site geometry and Mn ion oxidation state can only be readily distinguished based on a comparison of the calculated and experimental 14N azide and 17O HFCs. This comparison shows that only models containing a Jahn-Teller distorted 5-coordinate (MnIII)2 site and a 6 coordinate (MnIV)1 site can satisfactorily reproduce the experimental 14N and 17O hyperfine couplings.

AB - Natural halloysite (Al2Si2O5(OH)4. nH2O) nanotubes (HNT) are clay materials with hollow tubular structure and are widely applied in many fields. Many in vitro studies indicate that HNTs exhibit a high level of biocompatibility; however, the in vivo toxicity of HNTs remains unclear. In this study, the biodistribution and pulmonary toxicity of the purified HNTs in mice were investigated after intragastric administration for 30 days. HNTs have high stability in biological conditions. Oral administration of HNTs caused significant Al accumulation predominantly in the lung with relative slight effects on Si biodistribution. Oral administration of HNTs stimulated the growth of the mice at low dose (5 mg/kg BW) with no pulmonary toxicity but inhibited the mouse growth and resulted in oxidative stress and inflammation in lung at high dose (50 mg/kg BW). In addition, oral HNTs at high dose could be absorbed from the gastrointestinal tract and deposited in lung and could also induce pulmonary fibrosis.

We explore in detail the transmission of slow rotational motion from one gear to the next by these relatively simple molecules, so as to isolate and reveal the mechanisms of the relevant intermolecular interactions. Several characteristics of molecular gears are discussed, in particular the flexibility of the arms and the slipping and skipping between interlocking arms of adjacent gears, which differ from familiar macroscopic rigid gears. The underlying theoretical concepts suggest strongly that other analogous structures may also exhibit similar behavior which may inspire future exploration in designing large correlated molecular machines.

AB - Control of the biomaterial properties through stimuli-responsive polymeric platforms has become an essential technique in recent biomedical applications. A multilayer system of thiolated chitosan (t-Chi) and thiolated chondroitin sulfate (t-CS), consisting of five double layers ([t-Chi/t-CS]5), was fabricated here by applying a layer-by-layer coating strategy. To represent a novel class of chemically tunable nanostructures, the ability to cross-link pendant thiol groups was tested by a rise from pH 4 during layer formation to pH 9.3 and a more powerful chemical stimulus by using chloramine-T (ChT). Following both treatments, the resulting multilayers showed stimuli-dependent behavior, as demonstrated by their content of free thiols, wettability, surface charge, elastic modulus, roughness, topography, thickness, and binding of fibronectin. Studies with human dermal fibroblasts further demonstrated the favorable potential of the ChT-responsive multilayers as a cell-adhesive surface compared to pH-induced cross-linking. Because the [t-Chi/t-CS]5 multilayer system is responsive to stimuli such as the pH and redox environment, multilayer systems with disulfide bond formation may help to tailor their interaction with cells, film degradation, and controlled release of bioactive substances like growth factors in a stimuli-responsive manner useful in future wound healing and tissue engineering applications.

Therefore, an increasing need to valorize produced wastes arises. Waste materials originating from the food and agricultural industry can be considered as functional materials with interesting properties and broad application potential. Moreover, using an appropriate magnetic modification, smart materials exhibiting a rapid response to an external magnetic field can be obtained. Such materials can be easily and selectively separated from desired environments. Magnetically responsive waste derivatives of biological origins have already been prepared and used as efficient biosorbents for the isolation and removal of both biologically active compounds and organic and inorganic pollutants and radionuclides, as biocompatible carriers for the immobilization of diverse types of (bio)molecules, cells, nano- and microparticles, or (bio)catalysts. Potential bactericidal, algicidal, or anti-biofilm properties of magnetic waste composites have also been tested. Furthermore, low cost and availability of waste biomaterials in larger amounts predetermine their utilization in large-scale processes. PMID- 29470916 TI - Micromotors for "Chemistry-on-the-Fly". AB - This perspective reviews mobile micro/nanomotor scaffolds for performing "chemistry-on-the-fly". Synthetic nano/micromotors offer great versatility and distinct advantages in diverse chemical applications owing to their efficient propulsion and facile surface functionalization that allow these mobile platforms to move and disperse reactive materials across the solution. Such dynamic microreactors have led to accelerated chemical processes, including organic pollutant degradation, metal chelation, biorecognition, redox chemistry, chemical "writing", and a variety of other chemical transformations. Representative examples of such micromotor-enhanced chemical reactions are discussed, focusing on the specific chemical role of these mobile microreactors. The advantages, gaps and limitations of using micromotors as mobile chemical platforms are discussed, concluding with the future prospects of this emerging field. We envision that artificial nano/micromotors will become attractive dynamic tools for speeding up and enhancing "on-the-fly" chemical reactions.

AB - Cytosine methylation and demethylation play crucial roles in understanding the genomic DNA expression regulation. The epigenetic modification of cytosine and its continuous oxidative products are called the "new four bases of DNA" including 5-methylcytosine (5mC), 5-hydroxymethylcytosine (5hmC), 5 formylcytosine (5fC), and 5-carboxylcytosine (5caC). However, compared to the abundant studies on the classical DNA bases, the photophysical and photochemical properties of those new bases have not yet aroused people's excessive attention. In this contribution, a systematic study on the nonradiative decay and photochemical pathways via excited states or conical intersections upon photoexcitation has been explored through high-level computational approaches such as the complete active space self-consistent field method, complete active space with second-order perturbation theory, and density functional theory. Pathways like the ring-distortion deactivation, hydrogen dissociation, hydrogen transfer, and also Norrish type I and II photochemical reactions have been investigated, and it was proposed that intersystem crossing from the S1 state to the T1 state is the most effective route for 5fC. For 5caC, ring-pucking and intramolecular isomerism are effective deactivation ways at both neutral and protonated forms. In the meantime, the influences of two important environmental factors, the solution and acidic environment (i.e., the protonated state), were also considered in this study. From the theoretical perspective, the initial properties of the photostability and photochemical reactivity for 5fC and 5caC have become a crucial aspect to facilitate a further comprehension of their potential role in gene regulation and transcription. PMID- 29470918 TI - Early Immune Function and Duration of Organ Dysfunction in Critically III Children with Sepsis. AB - RATIONALE: Late immune suppression is associated with nosocomial infection and mortality in adults and children with sepsis. Relationships between early immune suppression and outcomes in children with sepsis remain unclear. OBJECTIVES: Prospective observational study to test the hypothesis that early innate and adaptive immune suppression are associated with longer duration of organ dysfunction in children with severe sepsis or septic shock. METHODS: Children younger than 18 years of age meeting consensus criteria for severe sepsis or septic shock were sampled within 48 hours of sepsis onset. Healthy control subjects were sampled once. Innate immune function was quantified by whole blood ex vivo LPS-induced TNF-alpha (tumor necrosis factor-alpha) production capacity. Adaptive immune function was quantified by ex vivo phytohemagglutinin-induced IFN gamma production capacity. MEASUREMENTS AND MAIN RESULTS: One hundred two children with sepsis and 35 healthy children were enrolled. Compared with healthy children, children with sepsis demonstrated lower LPS-induced TNF-alpha production (P < 0.0001) and lower phytohemagglutinin-induced IFN-gamma production (P < 0.0001). Among children with sepsis, early innate and adaptive immune suppression were associated with greater number of days with multiple organ dysfunction syndrome and greater number of days with any organ dysfunction. On multivariable analyses, early innate immune suppression remained independently associated with increased multiple organ dysfunction syndrome days (adjusted relative risk, 1.2; 95% confidence interval, 1.03-1.5) and organ dysfunction days (adjusted relative risk, 1.2; 95% confidence interval, 1.1-1.3). CONCLUSIONS: Critically ill children with severe sepsis or septic shock demonstrate early innate and adaptive immune suppression. Early innate and adaptive immune suppression are associated with longer durations of organ dysfunction and may be useful markers to help guide future investigations of immunomodulatory therapies in children with sepsis. PMID- 29470920 TI - Long-Term Microevolution of Pseudomonas aeruginosa Differs between Mildly and Severely Affected Cystic Fibrosis Lungs. AB - Chronic airway infections with Pseudomonas aeruginosa determine morbidity in most individuals with cystic fibrosis (CF). P. aeruginosa may persist for decades in CF lungs, which provides a rare opportunity to study the long-term within-host evolution of a bacterial airway pathogen. In this work, we sought to resolve the genetic adaptation of P. aeruginosa in CF lungs from the onset of colonization until the patient's death or permanent replacement by another P. aeruginosa clone. We followed the microevolution of the first persisting P. aeruginosa clone by whole-genome sequencing of serial isolates from highly divergent clinical courses of airway infection, i.e., a fatal outcome because of respiratory insufficiency within less than 15 years, or a rather normal daily life 25-35 years after acquisition of P. aeruginosa. Nonneutral mutations predominantly emerged in P. aeruginosa genes relevant for protection against and communication with signals from the lung environment, i.e., antibiotic resistance, cell wall components, and two-component systems. Drastic and loss-of-function mutations preferentially happened during the severe courses of infection, and the bacterial lineages of the mild courses more proficiently incorporated extra metabolic genes into their accessory genome. P. aeruginosa followed different evolutionary paths depending on whether the bacterium had taken up residence in a patient with CF and normal or already compromised lung function.

PMID- 29470929 TI - Interferon Alpha-2a for the Treatment of Post-Infectious Uveitis Secondary to Presumed Intraocular Tuberculosis. AB - PURPOSE: To assess the efficacy and tolerability of interferon (IFN) alpha-2a in post-infectious uveitis secondary to presumed intraocular tuberculosis (IOTB). METHODS: Patients with chronic uveitis secondary to presumed IOTB who, after completing an antitubercular treatment, showed poor response to treatments or recurred after tapering oral corticosteroids to <=7.5 mg/day were enrolled. All patients were treated with IFN alpha-2a subcutaneous injections. Best-corrected visual acuity (BCVA), central retinal thickness (CRT), and inflammatory signs were compared between baseline and follow-up visits up to six months. RESULTS: Twelve eyes (six patients) were enrolled. Mean BCVA improved from 0.64 +/- 0.55 logMAR at baseline to 0.32 +/- 0.31 logMAR at 6 months (p = 0.03). Mean CRT decreased from 372 +/- 132.2 MUm to 274.66 +/- 34.9 MUm at six months (p = 0.01). Inflammatory signs (vitritis, vasculitis) also decreased overtime. No major complications or tuberculosis reactivations were recorded. CONCLUSIONS: IFN alpha 2a was efficacious and safe in treating chronic post-infectious uveitis secondary to presumed IOTB. PMID- 29470930 TI - Diagnostic Utility of Quantitative Polymerase Chain Reaction versus Culture in Endophthalmitis and Uveitis. AB - PURPOSE: To compare genetic testing for microbes in infectious endophthalmitis or uveitis to culture. METHODS: This was a retrospective, single-center case series that enrolled patients with clinically suspected endophthalmitis or uveitis of unknown etiology. Aqueous humor or vitreous was collected and sent for routine cultures and genetic testing. RESULTS: In total, 46 patients were enrolled. Genetic testing was positive in 32/46 (70%) cases and culture 6/46 cases (13%). Five of 16 uveitis cases had a final clinical diagnosis of infectious uveitis, and polymerase chain reaction (PCR) was positive in 4/5 cases (80%), versus 0% for culture. In uveitis cases, PCR was 80% sensitive and 82% specific, and culture had 0% sensitivity. The overall sensitivity and specificity of PCR for all cases were 85% and 67%, respectively, compared with 17% and 100% for culture. CONCLUSION: Genetic assays are inexpensive ($25/case) and more sensitive than culture for identifying intraocular pathogens in endophthalmitis and uveitis.

AB - National Immunisation Technical Advisory Groups (NITAGs) provide independent guidance to health ministries to support evidence-based and nationally relevant immunisation decisions. We examined NITAGs' value, sustainability, and need for support in low and middle-income countries, drawing from a mixed-methods study including 130 global and national-level key informant interviews. NITAGs were particularly valued for providing independent and nationally owned evidence-based decision-making (EBDM), but needed to be integrated within national processes to effectively balance independence and influence. Participants agreed that most NITAGs, being relatively new, would need developmental and strengthening support for at least a decade. While national governments could support NITAG functioning, external support is likely needed for requisite capacity building. This might come from Gavi mechanisms and WHO, but would require alignment among stakeholders to be effective. PMID- 29470932 TI - Precise identification of wheat - Thinopyrum intermedium translocation chromosomes carrying resistance to wheat stripe rust in line Z4 and its derived progenies. AB - The wheat - Thinopyrum intermedium derived line Z4 has displayed novel and effective stripe rust resistance for over 40 years. This study aimed to precisely identify the chromosome constitution of line Z4 and determine the stripe rust resistance contribution using multicolor fluorescent in situ hybridization (FISH) and molecular marker analysis. The results indicated that the Z4 line (2n = 44) contained two pairs of non-Robertsonian translocations without the 3A chromosomes of wheat. FISH karyotypes of F3 progenies derived from crosses between Z4 and MY11 indicated that the transmission of the translocated chromosomes appeared normal and the number of wheat chromosomes 3A and 3D frequently varied. The FISH signal distribution of a new repetitive probe, named Oligo-3A1, confirmed the physical breakage points on chromosome 3AL incorporated into translocated chromosomes. PLUG markers revealed the breakage points on chromosomes 3A, 7JS, and 3D invloved in the translocated chromosomes, and they were designated as T3DS 3AS.3AL-7JSS and T3AL-7JSS.7JSL. Stripe rust resistances surveys indicated that the proximal region of 7JSS or 7JSL may confer the resistance at the adult plant stage. The precise characterization of the chromosome complements of wheat - Th. intermedium Z4 and derived progenies has demonstrated the importance of combining cytogenetic and molecular approaches in the genomics era for further wheat genetic manipulation and breeding purposes. PMID- 29470933 TI - Fluorescein Labeled Leukocytes for in vivo Imaging of Retinal Vascular Inflammation and Infiltrating Leukocytes in Laser-Induced Choroidal Neovascularization Model. AB - PURPOSE: To study the effect of anti-VEGF treatment on retinal inflammation in a laser-induced CNV rodent model. METHODS: Leukocytes labeled with 1% sodium fluorescein were injected into the laser-induced CNV (wild type C57BL/6) mice at days 4 (baseline), 7, 14, and 19. At baseline intravitreally 3 mice received 1* PBS, and 3 mice received anti-VEGF. FFA, OCT, and SLO were performed at each time point to assess the CNV pathophysiology and inflammatory response. RESULTS: Fluorescein leakage, SRF, and leukocyte infiltration were observed at baseline in both the groups before injection. From days 7 to 19, leukocyte infiltration and SRF were noted in the 1* PBS group, but limited or no SRF and leukocyte infiltration was observed in the anti-VEGF group. CONCLUSIONS: Leukocyte infiltration was established as an in vivo imaging inflammatory marker and along with FFA and OCT showed response to anti-VEGF therapy in laser-induced CNV model. PMID- 29470934 TI - Bivalent oral cholera vaccine in participants aged 1 year and older in the Dominican Republic: A phase III, single-arm, safety and immunogenicity trial. AB - The Dominican Republic, historically non-endemic for cholera, is experiencing an ongoing cholera epidemic. We assessed the safety and immunogenicity of two doses of the killed bivalent (O1 and O139) whole-cell oral cholera vaccine (OCV) on day (D)0 and D14 in healthy participants aged >=1 year. Immediate unsolicited systemic adverse events (AEs) were monitored up to 30 minutes and solicited systemic reactions, up to 7 days after each vaccination. Unsolicited AEs were recorded up to D14 (post-dose 1) and 30 days post-dose 2. A vibriocidal antibody assay with microtiter technique was used to measure serum antibodies to V. cholerae strains (O1 El Tor Inaba, O1 El Tor Ogawa, O139) on D0, D14 and D28. Geometric mean titers (GMTs) and seroconversion (>=4-fold increase from D0) rates were calculated. We recruited 336 participants; 112 in three age groups (1-4, 5 14 and >=15 years). No safety concerns were observed. GMTs increased from baseline for all serotypes, with marked increases for O1 Inaba and Ogawa post dose 1. Post-dose 2 GMTs tended to be equal or slightly lower, with ranges: O1 Inaba, 283 (95% confidence interval 191-419) to 612 (426-880); O1 Ogawa, 346 (223 536) to 754 (553-1028); and O139, 20.3 (13.5-30.6) to 43.8 (30.1-63.7). Seroconversion rates post-dose 2 for O1 Inaba and Ogawa were high (>=87%) for all age groups. OCV demonstrated an acceptable safety profile and robust immunogenicity in these participants, in-line with previous observations in epidemic and endemic settings.This study is registered on www.clinicaltrials.gov (NCT02434822). PMID- 29470937 TI - Renal Lesion Characterization with Spectral CT: Determining the Optimal Energy for Virtual Monoenergetic Reconstruction. AB - Purpose To investigate the relationship between energy level of virtual monoenergetic (VM) imaging and sensitivity in the detection of minimally enhancing renal lesions. Materials and Methods Phantoms simulating unenhanced and contrast material-enhanced renal parenchyma were equipped with inserts containing different concentrations of iodine (range, 0-1.15 mg iodine per milliliter). A total of 180 patients (117 men; mean age, 65.2 years +/- 13.0 [standard deviation]) with 194 (62 solid, 132 cystic) renal lesions larger than 10 mm in diameter underwent unenhanced single-energy CT and contrast-enhanced dual-energy CT. VM imaging data sets were created for 70, 80, 90, and 100 keV. Renal lesions were measured, and enhancement was calculated. Area under the receiver operating characteristic curve (AUC) for renal lesion characterization was determined by using the DeLong method. Results The AUC was highest at 70 keV and decreased as energy increased toward 100 keV. AUC in the phantom decreased from 98% (95% confidence interval [CI]: 95, 100) at 70 keV to 88% (95% CI: 79, 96) at 100 keV (P = .004). AUC in patients decreased from 96% (95% CI: 94, 98) at 70 keV to 79% (95% CI: 71, 86) at 100 keV (P = .001). In patients with an enhancement threshold of 15 HU, sensitivity in the detection of solid renal lesions decreased between from 91% (49 of 62 [95% CI: 78, 97]) at 70 keV to 48% (33 of 62 [95% CI: 25, 71]) at 100 keV (P < .05), with no change in specificity (93% [120 of 132 {95% CI: 87, 97}] at 70 keV, 97% [125 of 132 {95% CI: 92, 99}] at 100 keV). Conclusion There is a reduction in diagnostic accuracy for renal lesion characterization with increasing VM imaging energy. The 70-keV setting may provide an optimal trade-off between sensitivity and specificity. (c) RSNA, 2018 Online supplemental material is available for this article. PMID- 29470938 TI - Diagnostic Performance of MR Elastography for Liver Fibrosis in Children and Young Adults with a Spectrum of Liver Diseases. AB - Purpose To assess the diagnostic performance of magnetic resonance (MR) elastography-derived liver stiffness to detect liver fibrosis in a pediatric and young adult population with a spectrum of liver diseases. Materials and Methods This retrospective study included patients younger than 21 years of age who underwent MR elastography and liver biopsy within 3 months of one another between January 2012 and September 2016 for indications other than liver transplantation or Fontan palliation of congenital heart disease. MR elastography examinations were reprocessed by a single observer, blinded to pathologic findings. Pathology specimens were reviewed by a single pathologist who scored steatosis (lipid in >= 5% of hepatocytes) and staged fibrosis. Receiver operating characteristic (ROC) curves were used to assess diagnostic performance. Results A total of 86 patients, 49 (57%) male with a median age of 14.2 years (range, 0.3-20.6 years), were included. Fifty-one patients (59.3%) had Ludwig stage 2 or higher fibrosis; 44 patients (51.2%) had hepatic steatosis. The area under the ROC curve for Ludwig stage 0-1 versus stage 2 or higher fibrosis was 0.70 (95% confidence interval [CI]: 0.59, 0.81) for the whole population and was significantly lower for patients with steatosis versus those without (0.53 [95% CI: 0.35, 0.71] vs 0.82 [95% CI: 0.67, 0.96], P = .014). Optimal stiffness cut-offs for the entire population were 2.27 kPa with 68.6% sensitivity (95% CI: 57.2%, 80.1%) and 74.3% specificity (95% CI: 63.5%, 85.1%) or 1.67 kPa with 35.3% sensitivity (95% CI: 23.5%, 47.1%) and 91.4% specificity (95% CI: 84.5%, 98.3%). Conclusion In children and young adults, MR elastography performs significantly better for distinguishing stage 0-1 versus stage 2 or higher fibrosis in patients without steatosis than in those with steatosis. This suggests a confounding effect of steatosis or inflammation in the population with nonalcoholic fatty liver disease. (c) RSNA, 2018. PMID- 29470939 TI - Free-breathing Pulmonary MR Imaging to Quantify Regional Ventilation. AB - Purpose To measure regional specific ventilation with free-breathing hydrogen 1 (1H) magnetic resonance (MR) imaging without exogenous contrast material and to investigate correlations with hyperpolarized helium 3 (3He) MR imaging and pulmonary function test measurements in healthy volunteers and patients with asthma. Materials and Methods Subjects underwent free-breathing 1H and static breath-hold hyperpolarized 3He MR imaging as well as spirometry and plethysmography; participants were consecutively recruited between January and June 2017. Free-breathing 1H MR imaging was performed with an optimized balanced steady-state free-precession sequence; images were retrospectively grouped into tidal inspiration or tidal expiration volumes with exponentially weighted phase interpolation. MR imaging volumes were coregistered by using optical flow deformable registration to generate 1H MR imaging-derived specific ventilation maps. Hyperpolarized 3He MR imaging- and 1H MR imaging-derived specific ventilation maps were coregistered to quantify regional specific ventilation within hyperpolarized 3He MR imaging ventilation masks. Differences between groups were determined with the Mann-Whitney test and relationships were determined with Spearman (rho) correlation coefficients. Statistical analyses were performed with software. Results Thirty subjects (median age: 50 years; interquartile range [IQR]: 30 years), including 23 with asthma and seven healthy volunteers, were evaluated. Both 1H MR imaging-derived specific ventilation and hyperpolarized 3He MR imaging-derived ventilation percentage were significantly greater in healthy volunteers than in patients with asthma (specific ventilation: 0.14 [IQR: 0.05] vs 0.08 [IQR: 0.06], respectively, P < .0001; ventilation percentage: 99% [IQR: 1%] vs 94% [IQR: 5%], P < .0001). For all subjects, 1H MR imaging-derived specific ventilation correlated with plethysmography-derived specific ventilation (rho = 0.54, P = .002) and hyperpolarized 3He MR imaging derived ventilation percentage (rho = 0.67, P < .0001) as well as with forced expiratory volume in 1 second (FEV1) (rho = 0.65, P = .0001), ratio of FEV1 to forced vital capacity (rho = 0.75, P < .0001), ratio of residual volume to total lung capacity (rho = -0.68, P < .0001), and airway resistance (rho = -0.51, P = .004). 1H MR imaging-derived specific ventilation was significantly greater in the gravitational-dependent versus nondependent lung in healthy subjects (P = .02) but not in patients with asthma (P = .1). In patients with asthma, coregistered 1H MR imaging specific ventilation and hyperpolarized 3He MR imaging maps showed that specific ventilation was diminished in corresponding 3He MR imaging ventilation defects (0.05 +/- 0.04) compared with well-ventilated regions (0.09 +/- 0.05) (P < .0001). Conclusion 1H MR imaging-derived specific ventilation correlated with plethysmography-derived specific ventilation and ventilation defects seen by using hyperpolarized 3He MR imaging.

PMID- 29470944 TI - Antimicrobial resistance and prevalence of diarrheagenic Escherichia coli (DEC), in diarrheic yaks of Tibetan Plateau, China. AB - This study was conducted to test the distribution of diarrheagenic Escherichia coli (DEC) associated genes in fecal isolates from diarrheic yaks of a high remote region of China. Briefly, we obtained 203 fecal samples from diarrheic adult yaks and E. coli strains were isolated and identified via standard methods The antibiotic sensitivity of isolates was determined via disk diffusion method and polymerase chain reaction (PCR) was used to detect the DEC virulence associated genes. Results of the current study showed a high rate of resistance to tetracycline (93.6%) and low rate of resistance to ofloxacin (16.7%) antibiotics. Meanwhile, five different diarrheagenic associated virulence traits were detected including; EAEC (11.80%), EHEC (25.62%), EIEC (17.18%), EPEC (36.92%) and ETEC (11.36%). Moreover, E. coli isolates were positive for all tested DEC associated virulence genes ranging from 1.48% to 33%. Additionally, four isolates were positive for more than one virulence genes. In conclusion, our investigation showed a relatively low number of E. coli virulence genes isolated from diarrheic Tibetan yaks, which could be attributed to the high altitude induced harsh environmental conditions that may not help in the growth and survival of pathogenic organisms. In addition, this study highlights the high level of antibiotic resistance in yaks, therefore; preventive measures should be taken to monitor the antibiotic usage in Tibet region of China. PMID- 29470945 TI - Porcine circovirus 2 in the North Eastern region of India: Disease prevalence and genetic variation among the isolates from areas of intensive pig rearing. AB - Porcine Circovirus type-2 (PCV-2) is considered as a major threat to the piggery sector in India. To ascertain the epidemiological status and infection level of PCV2, a pilot study was undertaken to find out the prevalence of PCV2 in swine population by ELISA and PCR in the interior and border areas of Meghalaya which includes the area where accessibility and medical aid is a rare phenomenon. A total of 249 serum samples were collected from October 2014 to February 2016 from three divisions of Meghalaya: Khasi, Jaintia and Garo Hills Divisions. The mean positivity of PCV-2 antibodies in suspected sera was 83.93% whereas 62.25% of the suspected samples respectively were found to contain PCV2 as detected by PCR. Additional 190 tissue samples were collected during necropsy from both symptomatic and asymptomatic animals following reported outbreak in this region, which indicated a mean positivity of 18.94% (36/190); out of which 13 samples were subjected to sequencing to find out the genetic diversity of PCV2 amongst the field isolates. Molecular characterization and phylogenetic analysis of PCV2 isolates based on cap gene depicted genetic diversity among the strains in pig population of Meghalaya as the isolates belonged to PCV2a, PCV2b-1c and PCV2d genotypes; identification of the PCV2d genotype is probably the first report from Meghalaya. Four isolates forming an outlier group in the phylogenetic tree were arising out of natural inter-genotypic recombination between PCV2a and PCV2b. PCV2 being immunosuppressive in nature impairs the host immune response increasing the susceptibility to other co-infections leading to disease severity and high mortality in pig population. This baseline data gives a brief epidemiological status of PCV2 infection and circulating PCV2 genotype in this region which will be useful in the formulation of control and eradication programs in remotes areas of Meghalaya where accessibility is less and vaccination is a rare practice. PMID- 29470946 TI - Effect of ubiquinone-10 on the stability of biomimetic membranes of relevance for the inner mitochondrial membrane. AB - Ubiquinone-10 (Q10) plays a pivotal role as electron-carrier in the mitochondrial respiratory chain, and is also well known for its powerful antioxidant properties. Recent findings suggest moreover that Q10 could have an important membrane stabilizing function. In line with this, we showed in a previous study that Q10 decreases the permeability to carboxyfluorescein (CF) and increases the mechanical strength of 1-palmitoyl-2-oleyl-sn-glycero-phosphocholine (POPC) membranes. In the current study we report on the effects exerted by Q10 in membranes having a more complex lipid composition designed to mimic that of the inner mitochondrial membrane (IMM). Results from DPH fluorescence anisotropy and permeability measurements, as well as investigations probing the interaction of liposomes with silica surfaces, corroborate a membrane stabilizing effect of Q10 also in the IMM-mimicking membranes. Comparative investigations examining the effect of Q10 and the polyisoprenoid alcohol solanesol on the IMM model and on membranes composed of individual IMM components suggest, moreover, that Q10 improves the membrane barrier properties via different mechanisms depending on the lipid composition of the membrane. Thus, whereas Q10's inhibitory effect on CF release from pure POPC membranes appears to be directly and solely related to Q10's lipid ordering and condensing effect, a mechanism linked to Q10's ability to amplify intrinsic curvature elastic stress dominates in case of membranes containing high proportions of palmitoyl-2-oleoyl-sn-glycero-3 phosphoethanolamine (POPE). PMID- 29470947 TI - Small and large intestine express a truncated Dab1 isoform that assembles in cell cell junctions and co-localizes with proteins involved in endocytosis. AB - Disabled-1 (Dab1) is an essential intracellular adaptor protein in the reelin pathway. Our previous studies in mice intestine showed that Dab1 transmits the reelin signal to cytosolic signalling pathways. Here, we determine the Dab1 isoform expressed in rodent small and large intestine, its subcellular location and co-localization with clathrin, caveolin-1 and N-Wasp. PCR and sequencing analysis reveal that rodent small and large intestine express a Dab1 isoform that misses three (Y198, Y200 and Y220) of the five tyrosine phosphorylation sites present in brain Dab1 isoform (canonical) and contains nuclear localization and export signals. Western blot assays show that both, crypts, which shelter progenitor cells, and enterocytes express the same Dab1 isoform, suggesting that epithelial cell differentiation does not regulate intestinal generation of alternatively spliced Dab1 variants. They also reveal that the canonical and the intestinal Dab1 isoforms differ in their total degree of phosphorylation. Immunostaining assays show that in enterocytes Dab1 localizes at the apical and lateral membranes, apical vesicles, close to adherens junctions and desmosomes, as well as in the nucleus; co-localizes with clathrin and with N-Wasp but not with caveolin-1, and in Caco-2 cells Dab1 localizes at cell-to-cell junctions by a Ca2+-dependent process. In conclusion, the results indicate that in rodent intestine a truncated Dab1 variant transmits the reelin signal and may play a role in clathrin-mediated apical endocytosis and in the control of cell-to-cell junction assembly. A function of intestinal Dab1 variant as a nucleocytoplasmic shuttling protein is also inferred from its sequence and nuclear location.

Mass spectrometric analyses were performed online using ultra-high performance liquid chromatography (UHPLC)-electrospray ionization tandem mass spectrometry (LC-ESI MS/MS) in the negative multiple-reaction monitoring (MRM) modes. Rapid separation of PIP3 from PI, phosphatidylinositol phosphate (PIP) and PIP2 was accomplished by C18 reverse phase chromatography with the addition of the ion pairing reagents diisopropylethanolamine (DiiPEA) and ethylenediamine tetraacetic acid tetrasodium salt dihydrate (EDTA) to the samples and mobile phase with a total run time, including equilibration, of 12 min. Importantly, these chromatography conditions result in no carryover of PIP, PIP2, and PIP3 between samples. To validate the new method, U87MG cancer cells were serum starved and treated with PDGF to stimulate PIP3 biosynthesis in the presence or absence of the phosphatidylinositol 3-kinase (PI3K) inhibitor LY294002. Results generated with the LC/MS method were in excellent agreement with results generated using [33P] phosphate radiolabeled U87MG cells and anion exchange chromatography analysis, a well validated method for measuring PIP3. To demonstrate the usefulness of the new method, we generated reproducible IC50 data for several well-characterized PI3K small molecule inhibitors using a U87MG cell-based assay as well as showing PIP3 can be measured from additional cancer cell lines. Together, our results demonstrate this novel method is sensitive, reproducible and can be used to directly measure PIP3 without radiolabeling or complex lipid derivatization.

AB - F1 is a soluble part of FoF1-ATP synthase and performs a catalytic process of ATP hydrolysis and synthesis. The gamma subunit, which is the rotary shaft of F1 motor, is composed of N-terminal and C-terminal helices domains, and a protruding Rossman-fold domain located between the two major helices parts. The N-terminal and C-terminal helices domains of gamma assemble into an antiparallel coiled-coil structure, and are almost embedded into the stator ring composed of alpha3beta3 hexamer of the F1 molecule. Cyanobacterial and chloroplast gamma subunits harbor an inserted sequence of 30 or 39 amino acids length within the Rossman-fold domain in comparison with bacterial or mitochondrial gamma. To understand the structure-function relationship of the gamma subunit, we prepared a mutant F1-ATP synthase of a thermophilic cyanobacterium, Thermosynechococcus elongatus BP-1, in which the gamma subunit is split into N-terminal alpha-helix along with the inserted sequence and the remaining C-terminal part. The obtained mutant showed higher ATP-hydrolysis activities than those containing the wild-type gamma. Contrary to our expectation, the complexes containing the split gamma subunits were mostly devoid of the C-terminal helix. We further investigated the effect of post-assembly cleavage of the gamma subunit. We demonstrate that insertion of the nick between two helices of the gamma subunit imparts resistance to ADP inhibition, and the C-terminal alpha-helix is dispensable for ATP-hydrolysis activity and plays a crucial role in the assembly of F1-ATP synthase. PMID- 29470950 TI - Not seeking yet trying long-acting reversible contraception: a 24-month randomized trial on continuation, unintended pregnancy and satisfaction. AB - OBJECTIVES: To measure the 24-month impact on continuation, unintended pregnancy and satisfaction of trying long-acting reversible contraception (LARC) in a population seeking short-acting reversible contraception (SARC). STUDY DESIGN: We enrolled 916 women aged 18-29 who were seeking pills or injectables in a partially randomized patient preference trial. Women with strong preferences for pills or injectables started on those products, while others opted for randomization to LARC or SARC and received their methods gratis. We estimated continuation and unintended pregnancy rates through 24months. Intent-to-treat principles were applied after method initiation for comparing incidence of unintended pregnancy. We also examined how satisfaction levels varied by cohort and how baseline negative LARC attitudes were associated with satisfaction over time. RESULTS: Forty-three percent chose randomization, and 57% chose the preference option. Complete loss to follow-up was<2%. The 24-month LARC continuation probability was 64.3% [95% confidence interval (CI): 56.6-70.9], statistically higher than SARC groups [25.5% (randomized) and 40.0% (preference)]. The 24-month cumulative unintended pregnancy probabilities were 9.9% (95% CI: 7.2-12.6) (preference-SARC), 6.9% (95% CI: 3.3-10.6) (randomized SARC) and 3.6% (95% CI: 1.8-6.4) (randomized-LARC). Statistical tests for comparing randomized groups on unintended pregnancy were mixed: binomial at 24 month time point (p=.02) and log-rank survival probabilities (p=.14 for first pregnancies and p=.07 when including second pregnancies). LARC satisfaction was high (80% happy/neutral, 73% would use LARC again, 81% would recommend to a friend). Baseline negative attitudes toward LARC (27%) were not clearly associated with satisfaction or early discontinuation. CONCLUSIONS: The decision to try LARC resulted in high continuation rates and substantial protection from unintended pregnancy over 24months. Despite participants' initial desires to begin short-acting regimens, they had high satisfaction with LARC. Voluntary decisions to try LARC will benefit large proportions of typical SARC users. IMPLICATIONS: Even women who do not necessarily view LARC as a first choice may have a highly satisfying experience and avoid unintended pregnancy if they try it. PMID- 29470951 TI - Serum level of long noncoding RNA H19 as a diagnostic biomarker of multiple myeloma. AB - Circulating long noncoding RNA (lncRNA) H19 has been reported to be a biomarker for cancer monitoring. The purpose of this study was to determine whether serum lncRNA could serve as a novel biomarker for the diagnosis of multiple myeloma (MM) and evaluate its value of clinical application. In our study, the expression of lncRNA H19 was up-regulated in 80 patients with MM and MM cell lines by RT-PCR analysis. Clinicopathological analysis showed the expression level of H19 could assist clinical staging, and the severity of the disease could be roughly determined according to the amount of H19 expressed in the patient serum. This is the first report to show that H19 was expressed in the serum of MM patients, suggesting that upregulation of serum lncRNA H19 may prove to be a novel biomarker for early diagnosis and clinical treatment of MM. PMID- 29470952 TI - Urinary myeloperoxidase to creatinine ratio as a new marker for monitoring treatment effects of urinary tract infection. AB - OBJECTIVE: We want to determine whether urinary myeloperoxidase to creatinine ratio could be served as a new marker for monitoring treatment effects of urinary tract infection or not. METHODS: A total of 328 patients suspected of UTI were enrolled in present study. Patients been received antibiotic therapy within two weeks were excluded (n = 26). Patients with urine contaminated specimens (n = 49) and negative urine culture results (n = 96) were also excluded, the remaining culture positive subjects (n = 157) were followed up for 7 to 14 days, finally, a total of 49 subjects were followed up and further divided into cure (n = 35) and none-cure (n = 14) subgroups according to urine culture results. MPO concentration was determined by immunoturbidimetric method and creatinine level was measured by creatinine enzyme method. Two sided P values < 0.05 were considered statistically significant. RESULTS: Urinary MCR level between before and after antibiotic treatment of cure group were (1437.1 +/- 1777.9 vs.48.3 +/- 59.3, t = 4.608, P = 0.001), respectively. Urinary MCR level between before and after antibiotic treatment of none-cure group were (1633.1 +/- 2168.7 vs. 999.4 +/- 1708.0, t = 1.809, P = 0.094), respectively. CONCLUSIONS: Urinary MCR could be served as a promising marker for monitoring treatment effects of urinary tract infection. PMID- 29470953 TI - Cat preantral follicle survival after prolonged cooled storage followed by vitrification. AB - The aim of this study was to investigate the impact of prolonged storage at 4 degrees C on survival of cat preantral follicles (PAFs) pre- and post vitrification. Ovaries were obtained from 12 queens and transported at 4 oC within 2-6 h. Parts of the ovaries were stored for an additional 24 h or 72 h. The ovarian cortex was dissected, analyzed for viability (neutral red - NR) and morphology (histology - HE and ultrastructural analysis by TEM) and vitrified. We used 2 mm biopsy punches to obtain equal size pieces as the experimental units. After NR assessment, each sample was fixed and embedded in paraffin for HE staining to determine the number of morphologically intact follicles. Another 2 mm piece of ovary was subjected to TEM. NR viability assessment and HE results showed a similar tendency with PAF survival postvitrification even after prolonged cooling at 24 h and 72 h. With TEM, integrity of mitochondria, plasma and basal membranes as well as the presence of pre-granulose cells of PAFs were documented postvitrification for the control group and 24 h prolonged storage group, but not after 72 h storage. Our results showed that cat PAFs can survive prolonged storage followed by vitrification. The described set of techniques are applicable towards creating a gamete bank for endangered feline species. PMID- 29470954 TI - The optical properties of rat, porcine and human lenses in organ culture treated with dexamethasone. AB - Organ culturing of lenses is useful for testing the direct effect of moieties such as cations, glucose, oxygen, antioxidants or drugs on the lens. Lens opacity changes in organ cultured lenses have never been measured quantitatively. Our aims were twofold: to establish the time course of lens opacity changes in organ cultured rat, porcine and human lenses and to test the utility of our system to measure opacity changes in lenses treated with dexamethasone. Human, porcine and rat lenses were incubated with or without 5 MUM dexamethasone in minimum essential medium for 13 days. Lens absorbance and light scattering were measured using a spectrometer. Lens opacity was graded from lens photographs. Sixteen human lenses were obtained from 10 donors. Light scattering accounted for all of the absorbance of the human lens above 550 nm, 72% of the absorbance at 500 nm and 50% of the absorbance at 450 nm. Similarly, for the porcine lens, light scattering accounted for all of the absorbance above 400 nm and 40% of the absorbance at 350 nm. For the rat lens, scattering accounted for all of the absorbance above 325 nm, and 37% of the absorbance at 300 nm. In the rat lens spectrum, the broad absorbance peak near 600 nm was unique to the rat lens. After day five in organ culture, the level of light scattering, absorbance and optical grade of human lenses were higher in dexamethasone treated lenses compared with those without dexamethasone. Similar differences were observed for rat lenses after one day in organ culture. The opacity of porcine lenses did not change with dexamethasone treatment. In conclusion, this study showed that dexamethasone induced opacity in human and rat lenses could be measured which is important to future studies to test the positive or negative efficacy of moieties that cause or ameliorate cataract. PMID- 29470955 TI - PI3K regulates intraepithelial cell positioning through Rho GTP-ases in the developing neural tube. AB - Phosphatidylinositol 3-kinases (PI3Ks) are signal transducers of many biological processes. Class 1 A PI3Ks are hetero dimers formed by a regulatory and a catalytic subunit. We have used the developing chicken neural tube (NT) to study the roles played by PI3K during the process of cell proliferation and differentiation. Notably, we have observed that in addition to its well characterized anti apoptotic activity, PI3K also plays a crucial role in intra epithelial cell positioning, and unlike its role in survival that mainly depends on AKT, the activity in cell positioning is mediated by Rho GTPase family members. Additionally, we have observed that activating mutations of PI3K that are remarkably frequent in many human cancers, cause an unrestrained basal migration of the neuroepithelial cells that end up breaking through the basal membrane invading the surrounding mesenchymal tissue. The mechanism described in this work contribute not only to acquire a greater knowledge of the intraepithelial cell positioning process, but also give new clues on how activating mutations of PI3K contribute to cell invasion during the first stages of tumour dissemination. PMID- 29470956 TI - Metabolomic insights into the effects of thyroid hormone on Rana [Lithobates] catesbeiana metamorphosis using whole-body Matrix Assisted Laser Desorption/Ionization-Mass Spectrometry Imaging (MALDI-MSI). AB - Anuran metamorphosis involves the transformation of an aquatic tadpole into a juvenile frog. This process is completely dependent upon thyroid hormones (THs). Although much research has been focused on changes in gene expression programs during this postembryonic developmental period, transitions in the metabolic profiles are relatively poorly understood. Matrix Assisted Laser Desorption/Ionization-Mass Spectrometry Imaging (MALDI-MSI) is a technique that generates highly multiplexed mass spectra while retaining spatial location information on a thin tissue section. Reconstructed ion heat maps are correlated with morphology of the tissue section for biological interpretation. The present study is the first to use whole-body MALDI-MSI on tadpoles to gain insights into anuran metamorphosis. Approximately 1000 features were detected in each of five tissues examined (brain, eye, liver, notochord, and tail muscle) from premetamorphic North American bullfrog (Rana [Lithobates] catesbeiana) tadpoles. Of these detected metabolites, 1700 were unique and 136 were significantly affected by exposure to 50 nM thyroxine for 48 h. Of the significantly-affected metabolites, 64 features were tentatively identified using the MassTRIX annotation tool. All tissues revealed changes in lipophilic compounds including phosphatidylcholines, phosphatidylinositols, phosphatidylglycerols, phosphatidylethanolamines, and phosphatidylserines. These lipophilic compounds made up the largest portion of significantly-affected metabolites indicating that lipid signaling is a major target of TH action in frog tadpoles. PMID- 29470957 TI - Kaempferol 7-O-beta-D-glucoside isolated from the leaves of Cudrania tricuspidata inhibits LPS-induced expression of pro-inflammatory mediators through inactivation of NF-kappaB, AP-1, and JAK-STAT in RAW 264.7 macrophages. AB - Kaempferol 7-O-beta-D-glucoside (KPG), a natural flavonol isolated from Cudrania tricuspidata, has been reported to exert anti-cancer effects; however, its anti inflammatory effects have not yet been reported. In this study, we demonstrate the suppressive effect of KPG on the production of nitric oxide (NO), prostaglandin E2 (PGE2), tumor necrosis factor-alpha (TNF-alpha), interleukin 1beta (IL-1beta), and interleukin-6 (IL-6) in lipopolysaccharide (LPS)-induced RAW 264.7 macrophages and mouse bone marrow-derived macrophages. KPG downregulated the expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) at the protein level and iNOS, COX-2, TNF-alpha, IL 1beta, and IL-6 at the mRNA level in LPS-treated RAW 264.7 macrophages. Moreover, we elucidated the underlying molecular mechanism, demonstrating that KPG attenuated LPS-induced nuclear factor-kappaB (NF-kappaB) activation by decreasing p65 nuclear translocation, inhibiting kappaBalpha (IkappaBalpha) phosphorylation/degradation and IkappaB kinasealpha/beta (IKKalpha/beta) phosphorylation. KPG additionally reduced LPS-induced activator protein-1 (AP-1) activity by inhibiting c-Fos expression in the nucleus, though c-Jun was not affected. Furthermore, we revealed that KPG significantly abrogated the LPS induced phosphorylation of signal transducer and activator of transcription (STAT) 1 (Ser 727, Tyr 701) and STAT3 (Tyr 705) through inhibiting the phosphorylation of Janus kinase (JAK) 1 and JAK2, its upstream activating proteins. Taken together, our data suggest that KPG induces anti-inflammatory activity by blocking NF-kappaB, AP-1, and JAK-STAT signaling pathways in LPS treated RAW 264.7 macrophages, thus suppressing inflammatory mediators. PMID- 29470958 TI - Amentoflavone is a potent broad-spectrum inhibitor of human UDP glucuronosyltransferases. AB - Amentoflavone (AMF), an abundant natural biflavonoid found in many medicinal plants, displays various beneficial effects including anti-inflammatory, anti oxidative and anti-cancer. Despite the extensive studies on pharmacological activities, the toxicity or undesirable effects of AMF are rarely reported. In this study, the inhibitory effects of AMF on human UDP-glucuronosyltransferases (UGTs) were carefully investigated. AMF displayed strong inhibition towards most of human UGTs including UGT1A1, 1A3, 1A4, 1A6, 1A7, 1A8, 1A9, 1A10, 2B4 and 2B17, with the IC50 values ranging from 0.12 MUM to 16.81 MUM. Inhibition constants (Ki) of AMF against various human UGTs varied from 0.29 MUM to 11.51 MUM. Further investigation demonstrated that AMF was a noncompetitive inhibitor of UGT1A1 mediated NCHN-O-glucuronidation but functioned as a competitive inhibitor of UGT1A1 mediated 4-MU-O-glucuronidation. In addition, AMF was a competitive inhibitor of UGT1A4 mediated TFP-N-glucuronidation in both UGT1A4 and human liver microsomes, while functioned as a competitive inhibitor of UGT1A9 mediated propofol or 4-MU-O-glucuronidation. These findings demonstrated that AMF was a strong and broad-spectrum natural inhibitor of most human UGTs, which might bring potential risks of herb-drug interactions (HDIs) via UGT inhibition. Additionally, this study provided novel insights into the underlying mechanism of AMF-associated toxicity from the perspective of UGT inhibition. PMID- 29470959 TI - Differential effects of serotonin reuptake inhibitors fluoxetine and escitalopram on bone markers and microarchitecture in Wistar rats. AB - Evidence from several studies indicates that the long-term treatment of selective serotonin reuptake inhibitors (SSRIs) is associated with a decrease in bone mass and increase the risk of fractures. The present work evaluated and compared the effect of treatment with two SSRIs viz. fluoxetine and escitalopram on bone biomarkers (P1NP and betaCTX) in male Wistar rats. In addition, the effect of these drugs on bone microarchitecture of lumbar and tibia bones was carried out. Fluoxetine (8.2 mg/kg) treatment for 40 days significantly reduced (P < 0.01) the levels of the P1NP while escitalopram (2.0 mg/kg) was without such effects. Both drugs were devoid of any effects on bone resorption marker betaCTX. The pCREB levels were reduced by both the antidepressants but the reduction was significantly (P < 0.001) marked in case of fluoxetine. The micro-CT data revealed that fluoxetine, but not escitalopram, treatment resulted in reduced bone volume fraction, trabecular thickness and number while increased trabecular separation, trabecular pattern factor and connectivity density in the proximal tibial metaphysis. No significant changes were, however, discernible in lumbar bones. The study shows that fluoxetine reduces bone formation possibly through reduced pCREB mediated by the action of gut serotonin in osteoblasts and that escitalopram can be a better treatment option as far as adverse effects on bone are concerned. PMID- 29470960 TI - Establishment of reference intervals for the salivary cortisol circadian cycle, by electrochemiluminescence (ECLIA), in healthy adults. AB - OBJECTIVES: To determine salivary cortisol reference intervals in a healthy adult population, at 6 different time points during a 24-hour (h) period. METHODS: In a prospective study, salivary cortisol concentrations were measured upon waking, one-hour post-waking and at specific times of the day: at 12 h00, 16 h00, 20 h00 and midnight. Samples were analyzed by the first and second-generation electrochemiluminescence assays (ECLIA) from Roche Cobas Cortisol(r). RESULTS: Salivary cortisol values were obtained from 134 healthy volunteers. Reference intervals for the first-generation assay were 6.14-33.19 nmol/L (95% prediction interval) at waking, 5.42-28.06 nmol/L one-hour post-waking, 3.62-16.23 nmol/L at 12 h00, 2.78-15.27 nmol/L at 16 h00, 2.08-14.90 nmol/L at 20 h00 and 2.09-16.92 nmol/L at midnight. Mean salivary cortisol values were 14.63 nmol/L at waking and 6.44 nmol/L at midnight. Reference intervals for the second-generation assay were 1.50-22.02 nmol/L (2.5th to 97.5th percentiles) at waking, 1.50-20.87 nmol/L one hour post-waking, 1.50-12.51 nmol/L at 12 h00, 1.50-13.03 nmol/L at 16 h00, 1.50 9.52 nmol/L at 20 h00 and 1.50-6.28 nmol/L at midnight. Values for the second generation assay at all 6 different time points were almost half of the first generation assay. The second-generation assay showed a better correlation with LC MS/MS (r = 0,97). CONCLUSION: Our study confirms that reference intervals for salivary cortisol are not comparable across first and second-generation Roche Cobas Cortisol(r) assays. Furthermore, the second-generation assay has a better correlation with LC-MS/MS and a better analytical performance (accuracy and precision). PMID- 29470961 TI - Mechano-growth factor protects against mechanical overload induced damage and promotes migration of growth plate chondrocytes through RhoA/YAP pathway. AB - Epiphyseal growth plate is highly dynamic tissue which is controlled by a variety of endocrine, paracrine hormones, and by complex local signaling loops and mechanical loading. Mechano growth factor (MGF), the splice variant of the IGF-I gene, has been discovered to play important roles in tissue growth and repair. However, the effect of MGF on the growth plate remains unclear. In the present study, we found that MGF mRNA expression of growth plate chondrocytes was upregulated in response to mechanical stimuli. Treatment of MGF had no effect on growth plate chondrocytes proliferation and differentiation. But it could inhibit growth plate chondrocytes apoptosis and inflammation under mechanical overload. Moreover, both wound healing and transwell assay indicated that MGF could significantly enhance growth plate chondrocytes migration which was accompanied with YAP activation and nucleus translocation. Knockdown of YAP with YAP siRNA suppressed migration induced by MGF, indicating the essential role of YAP in MGF promoting growth plate chondrocytes migration. Furthermore, MGF promoted YAP activation through RhoA GTPase mediated cytoskeleton reorganization, RhoA inhibition using C3 toxin abrogated MGF induced YAP activation. Importantly, we found that MGF promoted focal adhesion(FA) formation and knockdown of YAP with YAP siRNA partially suppressed the activation of FA kinase, implying that YAP is associated with FA formation. In conclusion, MGF is an autocrine growth factor which is regulated by mechanical stimuli. MGF could not only protect growth plate chondrocytes against damage by mechanical overload, but also promote migration through activation of RhoA/YAP signaling axis. Most importantly, our findings indicate that MGF promote cell migration through YAP mediated FA formation to determine the FA-cytoskeleton remodeling. PMID- 29470963 TI - Autoantibodies Hurt: Transfer of Patient-Derived CASPR2 Antibodies Induces Neuropathic Pain in Mice. AB - In this issue of Neuron, Dawes et al. (2018) show that CASPR2 antibodies (Abs) isolated from patients bind specifically to primary afferent cell bodies and induce neuropathic pain in mice. Consequent decreased expression of Kv1 channels and their aberrant localization along myelinated axons explain the observed hyperexcitability and pain. PMID- 29470962 TI - Indomethacin induced glioma apoptosis involving ceramide signals. AB - Nonsteroidal anti-inflammatory drugs (NSAIDs) are increasingly implicated in the prevention and treatment of cancers apart from their known inhibitory effects on eicosanoid production. One of the NSAIDs, indomethacin, in particular shows promising antineoplastic outcome against glioma. To extend such finding, we here studied in human H4 and U87 glioma cells the possible involvement of the ceramide/protein phosphatase 2 A (PP2A)/Akt axis in the indomethacin-induced apoptosis. We found that the induced apoptosis was accompanied by a series of biochemical events, including intracellular ceramide generation, PP2A activation, Akt dephosphorylation, Mcl-1 and FLICE inhibiting protein (FLIP) transcriptional downregulation, Bax mitochondrial distribution, and caspase 3 activation. Such events were also duplicated with a cell-permeable C2-ceramide and Akt inhibitor LY294002. Pharmacological inhibition of ceramide synthase by fumonisin B1 and PP2A by okadaic acid moderately attenuated indomethacin-induced Akt dephosphorylation along with the apoptosis. Results suggested that the ceramide/PP2A/Akt axis is involved in the apoptosis and a possible cyclooxygenase independent target for indomethacin. Furthermore, apoptosis regulatory proteins such as Mcl-1 and FLIP are potential downstream effectors of this axis and their downregulation could turn on the apoptotic program.

PMID- 29470967 TI - A Spotlight on Appetite. AB - Remarkably few hormones have been identified that stimulate appetite. The recent discovery of asprosin, a hormone that activates AgRP neurons to increase food intake and body weight, begins to fill this gap (Duerrschmid et al., 2017; Romere et al., 2016). PMID- 29470968 TI - Multiple Sclerosis: Mechanisms and Immunotherapy. AB - Multiple sclerosis (MS) is an autoimmune disease triggered by environmental factors that act on a genetically susceptible host. It features three clinical stages: a pre-clinical stage detectable only by MRI; a relapsing-remitting (RRMS) stage characterized by episodes of neurologic dysfunction followed by resolution; and a progressive stage, which usually evolves from the relapsing stage. Advances in our understanding of the immune mechanisms that contribute to MS have led to more than ten FDA-approved immunotherapeutic drugs that target effector T cells, regulatory cells, B cells, and cell trafficking into the nervous system. However, most drugs for relapsing MS are not effective in treating progressive disease. Progressive MS features a compartmentalized immune response in the central nervous system, involving microglia cells and astrocytes, as well as immune independent processes that drive axonal dysfunction. Major challenges for MS research involve understanding the mechanisms of disease progression, developing treatment for progressive MS, and determining the degree to which progressive disease can be prevented by early treatment. Key priorities for MS research include developing biomarkers, personalized medicine and advanced imaging, and a better understanding of the microbiome. With a better understanding of the genetic and epidemiological aspects of this disease, approaches to prevent MS are now also being considered. PMID- 29470970 TI - Comparisons Between Histology and Optical Coherence Tomography Angiography of the Periarterial Capillary-Free Zone. AB - PURPOSE: To use the capillary-free zone along retinal arteries, a physiologic area of superficial avascularization, as an anatomic paradigm to investigate the reliability of optical coherence tomography angiography (OCTA) for visualizing the deep retinal circulation. DESIGN: Validity analysis and laboratory investigation. METHODS: Five normal human donor eyes (mean age 69.8 years) were perfusion-labeled with endothelial antibodies and the capillary networks of the perifovea were visualized using confocal scanning laser microscopy. Regions of the capillary-free zone along the retinal artery were imaged using OCTA in 16 normal subjects (age range 24-51 years). Then, 3 * 3-mm scans were acquired using the RTVue XR Avanti (ver. 2016.1.0.26; Optovue, Inc, Fremont, California, USA), PLEX Elite 9000 (ver. 1.5.0.15909; Zeiss Meditec, Inc, Dublin, California, USA), Heidelberg Spectralis OCT2 (Family acquisition module 6.7.21.0; Heidelberg Engineering, Heidelberg, Germany), and DRI-OCT Triton (Ver. 1.1.1; Topcon Corp, Tokyo, Japan). Images of the superficial plexus, deep vascular plexus, and a slab containing all vascular plexuses were generated using manufacturer-recommended default settings. Comparisons between histology and OCTA were performed. RESULTS: Histologic analysis revealed that the capillary-free zone along the retinal artery was confined to the plane of the superficial capillary plexus and did not include the intermediate and deep capillary plexuses. Images derived from OCTA instruments demonstrated a prominent capillary-free zone along the retinal artery in slabs of the superficial plexus, deep plexus, and all capillary plexuses. The number of deep retinal capillaries seen in the capillary-free zone was significantly greater on histology than on OCTA (P < .001). CONCLUSION: Using the capillary-free zone as an anatomic paradigm, we show that the deep vascular beds of the retina are not completely visualized using OCTA. This may be a limitation of current OCTA techniques. PMID- 29470971 TI - Use of Autologous Serum Tears for the Treatment of Ocular Surface Disease From Patients With Systemic Autoimmune Diseases. AB - PURPOSE: To describe the safety and efficacy of autologous serum tears (AST) in managing ocular surface disease resistant to conventional therapy in patients with systemic autoimmune disease(s). DESIGN: Retrospective, interventional case series. METHODS: Records of patients from 2009 to 2015 with systemic autoimmune disease treated with AST (20%-50%) for chronic surface disease were analyzed. Standardized measures of subjective dry eye symptoms, objective dry eye staining of the cornea, and slit-lamp findings including punctate epithelial erosion (PEE), filamentary keratopathy (FK), and corneal epithelial defects (KED) were compared during first and last visit. We attempted to standardize outcomes by creating a scale from 1 to 4 for subjective and objective components: worsening (1), no improvement (2), partial improvement (3), and complete resolution (4). RESULTS: Fifty-one patients (101 eyes) were included. The mean age was 59.8 +/- 13.2 years (72.5% female). Average use of AST was 14.3 +/- 11.7 months. Complete objective improvement of initial slit-lamp findings was achieved in 30% and partial improvement in 55% of eyes. Presence of PEE, FK, and KED decreased from 92.1% to 52.5% (P < .001), from 22.8% to 9.9% (P = .02), and from 5% to 2% (P = .44) of the eyes, respectively. Full subjective improvement of symptoms was achieved in 34.6%, partial in 50.5%, and none in 14.9% of patients. No adverse side effects were noted during follow-up. CONCLUSIONS: AST are a safe and effective adjunct therapy in improving both objective signs and subjective symptoms of ocular surface disorders associated with systemic autoimmune disease(s). PMID- 29470972 TI - Influence of Nasal Tear Osmolarity on Ocular Symptoms Related to Dry Eye Disease. AB - PURPOSE: To investigate relationships between local tear osmolarity and tear film characteristics and dry eye disease (DED) symptoms. DESIGN: Prospective, cross sectional, observational study. METHODS: Nasal and temporal tear osmolarity were measured in subjects with DED. The difference between nasal and temporal tears (OSM difference) was then calculated. Ocular symptoms were evaluated and tear break-up time (TBUT), corneal fluorescein staining score (CFSS), eyelid hyperemia, and tear production were measured. Correlations between DED symptoms and nasal tear osmolarity, temporal tear osmolarity, OSM difference, and tear film characteristics were evaluated using Pearson correlation analyses. Subjects were divided into 3 groups based on OSM difference: the temporal group had a temporal osmolarity > nasal osmolarity, the nasal group had a temporal osmolarity < nasal osmolarity, and the equal group had an OSM difference < 10 mOsm/L. RESULTS: Forty-eight eyes of 48 subjects were included. Eleven eyes were in the temporal group, 17 eyes were in the equal group, and 20 eyes were in the nasal group. Temporal osmolarity, nasal osmolarity, and OSM difference were not correlated with TBUT, CFSS, lid hyperemia, or tear production. Nasal tear osmolarity was correlated with cold sensitivity frequency (r = 0.298, P = .040), foreign body sensation severity (r = 0.293, P = .043), and light sensitivity severity (r = 0.293, P = .043). Additionally, OSM difference was correlated with daily symptom frequency (r = 0.339, P = .019). CONCLUSIONS: Nasal tear osmolarity and OSM difference play an important role in DED symptoms. Lid hyperemia, TBUT, CFSS, and tear secretion volume are not significantly affected by tear osmolarity. It is important to measure both nasal and temporal tear osmolarity when evaluating patients with DED. PMID- 29470969 TI - Neuromodulation of Attention. AB - Attention is critical to high-level cognition and attention deficits are a hallmark of neurologic and neuropsychiatric disorders. Although years of research indicates that distinct neuromodulators influence attentional control, a mechanistic account that traverses levels of analysis (cells, circuits, behavior) is missing. However, such an account is critical to guide the development of next generation pharmacotherapies aimed at forestalling or remediating the global burden associated with disorders of attention. Here, we summarize current neuroscientific understanding of how attention affects single neurons and networks of neurons. We then review key results that have informed our understanding of how neuromodulation shapes these neuron and network properties and thereby enables the appropriate allocation of attention to relevant external or internal events. Finally, we highlight areas where we believe hypotheses can be formulated and tackled experimentally in the near future, thereby critically increasing our mechanistic understanding of how attention is implemented at the cellular and network levels. PMID- 29470973 TI - Long-term Surgical Outcomes for Large-angle Infantile Esotropia. AB - PURPOSE: To report the long-term surgical outcomes for a cohort of children with large-angle infantile esotropia. DESIGN: Multicenter, nonrandomized clinical study. METHODS: Setting: Two tertiary-care pediatric hospitals. STUDY POPULATION: Children with large-angle (>=55 prism diopters) infantile esotropia. INTERVENTION: Surgical treatment of infantile esotropia. MAIN OUTCOME MEASURE: Success rate at final follow-up (postoperative deviation <= 10 prism diopters and no need for retreatment). RESULTS: A total of 88 patients with large-angle infantile esotropia were treated during the 13-year study period. Treatment was bilateral medial rectus muscle recessions in 70 patients, botulinum toxin augmented surgery in 15 patients, and 3-muscle surgery in 3 patients. After a mean follow-up of 40 months, 20 patients (23%) had a successful outcome compared to 68 treatment failures (77%). Of the 68 treatment failures, 59 had residual or recurrent esotropia and 9 had sequential exotropia. On multivariate logistic regression, treatment modality was the only factor significantly associated with a successful outcome. Specifically, patients treated with botulinum toxin augmented surgery were more likely to have a successful outcome compared to patients treated with bilateral medial rectus muscle recessions. For the 26 patients (30%) who underwent retreatment, the mean number of procedures was 2.1, and 7 (27%) had a deviation of <=10 prism diopters at final follow-up. CONCLUSIONS: The overall success rate for treatment of large-angle infantile esotropia was poor in this cohort, with most failures owing to recurrent or residual esotropia. Botulinum toxin-augmented surgery was associated with a higher success rate at final follow-up. PMID- 29470974 TI - A step towards standardization: A method for end-point titer determination by fluorescence index of an automated microscope. End-point titer determination by fluorescence index. AB - OBJECTIVES: Indirect Immunofluorescence (IIF) is widely considered the Gold Standard for Antinuclear Antibody (ANA) screening. However, the high inter-reader variability remains the major disadvantage associated with ANA testing and the main reason for the increasing demand of the computer-aided immunofluorescence microscope. Previous studies proposed the quantification of the fluorescence intensity as an alternative for the classical end-point titer evaluation. However, the different distribution of bright/dark light linked to the nature of the self-antigen and its location in the cells result in different mean fluorescence intensities. The aim of the present study was to correlate Fluorescence Index (F.I.) with end-point titers for each well-defined ANA pattern. METHODS: Routine serum samples were screened for ANA testing on HEp-2000 cells using Immuno Concepts Image Navigator System, and positive samples were serially diluted to assign the end-point titer. A comparison between F.I. and end point titers related to 10 different staining patterns was made. RESULTS: According to our analysis, good technical performance of F.I. (97% sensitivity and 94% specificity) was found. A significant correlation between quantitative reading of F.I. and end-point titer groups was observed using Spearman's test and regression analysis. A conversion scale of F.I. in end-point titers for each recognized ANA-pattern was obtained. CONCLUSIONS: The Image Navigator offers the opportunity to improve worldwide harmonization of ANA test results. In particular, digital F.I. allows quantifying ANA titers by using just one sample dilution. It could represent a valuable support for the routine laboratory and an effective tool to reduce inter- and intra-laboratory variability. PMID- 29470975 TI - High-throughput screening of T7 phage display and protein microarrays as a methodological approach for the identification of IgE-reactive components. AB - Olive pollen and yellow mustard seeds are major allergenic sources with high clinical relevance. To aid with the identification of IgE-reactive components, the development of sensitive methodological approaches is required. Here, we have combined T7 phage display and protein microarrays for the identification of allergenic peptides and mimotopes from olive pollen and mustard seeds. The identification of these allergenic sequences involved the construction and biopanning of T7 phage display libraries of mustard seeds and olive pollen using sera from allergic patients to both biological sources together with the construction of phage microarrays printed with 1536 monoclonal phages from the third/four rounds of biopanning. The screening of the phage microarrays with individual sera from allergic patients enabled the identification of 10 and 9 IgE reactive unique amino acid sequences from olive pollen and mustard seeds, respectively. Five immunoreactive amino acid sequences displayed on phages were selected for their expression as His6-GST tag fusion proteins and validation. After immunological characterization, we assessed the IgE-reactivity of the constructs. Our results show that protein microarrays printed with T7 phages displaying peptides from allergenic sources might be used to identify allergenic components -peptides, proteins or mimotopes- through their screening with specific IgE antibodies from allergic patients. PMID- 29470976 TI - Evaluation of methods to reduce background using the Python-based ELISA_QC program. AB - Almost all immunological approaches [immunohistochemistry, enzyme-linked immunosorbent assay (ELISA), Western blot], that are used to quantitate specific proteins have had to address high backgrounds due to non-specific reactivity. We report here for the first time a quantitative comparison of methods for reduction of the background of commercial biotinylated antibodies using the Python-based ELISA_QC program. This is demonstrated using a recombinant humanized anti-cocaine monoclonal antibody. Several approaches, such as adjustment of the incubation time and the concentration of blocking agent, as well as the dilution of secondary antibodies, have been explored to address this issue. In this report, systematic comparisons of two different methods, contrasted with other more traditional methods to address this problem are provided. Addition of heparin (HP) at 1 MUg/ml to the wash buffer prior to addition of the secondary biotinylated antibody reduced the elevated background absorbance values (from a mean of 0.313 +/- 0.015 to 0.137 +/- 0.002). A novel immunodepletion (ID) method also reduced the background (from a mean of 0.331 +/- 0.010 to 0.146 +/- 0.013). Overall, the ID method generated more similar results at each concentration of the ELISA standard curve to that using the standard lot 1 than the HP method, as analyzed by the Python-based ELISA_QC program. We conclude that the ID method, while more laborious, provides the best solution to resolve the high background seen with specific lots of biotinylated secondary antibody. PMID- 29470977 TI - The unfolded protein response in ischemic heart disease. AB - Ischemic heart disease is a severe stress condition that causes extensive pathological alterations and triggers cardiac cell death. Accumulating evidence suggests that the unfolded protein response (UPR) is strongly induced by myocardial ischemia. The UPR is an evolutionarily conserved cellular response to cope with protein-folding stress, from yeast to mammals. Endoplasmic reticulum (ER) transmembrane sensors detect the accumulation of unfolded proteins and stimulate a signaling network to accommodate unfolded and misfolded proteins. Distinct mechanisms participate in the activation of three major signal pathways, viz. protein kinase RNA-like ER kinase, inositol-requiring protein 1, and activating transcription factor 6, to transiently suppress protein translation, enhance protein folding capacity of the ER, and augment ER-associated degradation to refold denatured proteins and restore cellular homeostasis. However, if the stress is severe and persistent, the UPR elicits inflammatory and apoptotic pathways to eliminate terminally affected cells. The ER is therefore recognized as a vitally important organelle that determines cell survival or death. Recent studies indicate the UPR plays critical roles in the pathophysiology of ischemic heart disease. The three signaling branches may elicit distinct but overlapping effects in cardiac response to ischemia. Here, we outline the findings and discuss the mechanisms of action and therapeutic potentials of the UPR in the treatment of ischemic heart disease. PMID- 29470978 TI - Contractile responses to endothelin-1 are regulated by PKC phosphorylation of cardiac myosin binding protein-C in rat ventricular myocytes. AB - The shortening of sarcomeres that co-ordinates the pump function of the heart is stimulated by electrically-mediated increases in [Ca2+]. This process of excitation-contraction coupling (ECC) is subject to modulation by neurohormonal mediators that tune the output of the heart to meet the needs of the organism. Endothelin-1 (ET-1) is a potent modulator of cardiac function with effects on contraction amplitude, chronotropy and automaticity. The actions of ET-1 are evident during normal adaptive physiological responses and increased under pathophysiological conditions, such as following myocardial infarction and during heart failure, where ET-1 levels are elevated. In myocytes, ET-1 acts through ETA or ETB-G protein-coupled receptors (GPCRs). Although well studied in atrial myocytes, the influence and mechanisms of action of ET-1 upon ECC in ventricular myocytes are not fully resolved. We show in rat ventricular myocytes that ET-1 elicits a biphasic effect on fractional shortening (initial transient negative and sustained positive inotropy) and increases the peak amplitude of systolic Ca2+ transients in adult rat ventricular myocytes. The negative inotropic phase was ETB receptor-dependent, whereas the positive inotropic response and increase in peak amplitude of systolic Ca2+ transients required ETA receptor engagement. Both effects of ET-1 required phospholipase C (PLC)-activity, although distinct signalling pathways downstream of PLC elicited the effects of each ET receptor. The negative inotropic response involved inositol 1,4,5-trisphosphate (InsP3) signalling and protein kinase C epsilon (PKCepsilon). The positive inotropic action and the enhancement in Ca2+ transient amplitude induced by ET-1 were independent of InsP3 signalling, but suppressed by PKCepsilon. Serine 302 in cardiac myosin binding protein-C was identified as a PKCepsilon substrate that when phosphorylated contributed to the suppression of contraction and Ca2+ transients by PKCepsilon following ET-1 stimulation. Thus, our data provide a new role and mechanism of action for InsP3 and PKCepsilon in mediating the negative inotropic response and in restraining the positive inotropy and enhancement in Ca2+ transients following ET-1 stimulation. PMID- 29470979 TI - Transcriptional information revealed differentially expressed circular RNAs in facet joint osteoarthritis. AB - Circular RNAs are newly identified RNAs that regulate gene expression and execute various biological activities. Facet joint osteoarthritis (FJOA) is a severe facet joint cartilage degeneration disease that induces chronic low back pain to a larger population. The molecular mechanisms of FJOA, especially the presence and changes of circular RNAs in FJOA have not been investigated. In the current study, we analyzed RNA deep sequencing outcomes from healthy control group and FJOA group, identified and annotated circular RNAs, and determined the expressions of circular RNAs. Differentially expressed circular RNAs in the FJOA group were then screened and the host genes of these differentially expressed circular RNAs were functional analyzed by Gene Ontology (GO), Kyoto Enrichment of Genes and Genomes (KEGG), and protein-protein interaction network analysis. Seven circRNAs were arbitrarily selected to confirm the trustworthiness of these profiles by quantitative qRT-PCR. The potential binding sites of microRNAs (miRNAs) and identified circular RNAs were also predicted. Our current study provided valuable bioinformation regarding circular RNAs in FJOA and expanded our knowledge of FJOA. PMID- 29470980 TI - Graphene coating on the surface of CoCrMo alloy enhances the adhesion and proliferation of bone marrow mesenchymal stem cells. AB - The objective was to investigate whether a graphene coating could improve the surface bioactivity of a cobalt-chromium-molybdenum-based alloy (CoCrMo). Graphene was produced by chemical vapor deposition and transferred to the surface of the CoCrMo alloy using an improved wet transfer approach. The morphology of the samples was observed, and the adhesion force and stabilization of graphene coating were analyzed by a nanoscratch test and ultrasonication test. In an in vitro study, the adhesion and proliferation of bone marrow mesenchymal stem cells (BMSCs) cultured on the samples were quantified via an Alamar Blue assay and cell counting kit-8 (CCK-8) assay. The results showed that it is feasible to apply graphene to modify the surface of a CoCrMo alloy, and the enhancement of the adhesion and proliferation of BMSCs was also shown in the present study. In conclusion, graphene exhibits considerable potential for enhancing the surface bioactivity of CoCrMo alloy. PMID- 29470981 TI - GhoT of the GhoT/GhoS toxin/antitoxin system damages lipid membranes by forming transient pores. AB - GhoT is a bacterial toxin of the type V toxin/antitoxin system that allows Escherichia coli to reduce its metabolism in response to oxidative and bile stress. GhoT functions by increasing membrane permeability and reducing both ATP levels and the proton motive force. However, how GhoT damages the inner membrane has not been elucidated. Here we investigated how GhoT damages membranes by studying its interaction with lipid bilayers and determined that GhoT does not cause macroscopic disruption of the lipid bilayer to increase membrane permeability to the dye carboxyfluorescein. Using circular dichroism, we found that GhoT forms an alpha helical structure in lipid bilayers that agrees with the structure predicted by the I-TASSER protein structure prediction program. The structure generated using I-TASSER was used to conduct coarse-grained molecular dynamics simulations, which indicate that GhoT damages the cell membrane, as a multimer, by forming transient transmembrane pores. PMID- 29470982 TI - RIP3 deficiency protects against traumatic brain injury (TBI) through suppressing oxidative stress, inflammation and apoptosis: Dependent on AMPK pathway. AB - Traumatic brain injury (TBI) is a leading cause of disability and mortality in young adults worldwide. The pathophysiology is not fully understood. Programmed necrosis (necroptosis) is a newly identified mechanism of cell death combining features of both apoptosis and necrosis. Receptor-interacting protein 3 (RIP3) plays an important role in programmed necrosis. However, the effect of RIP3 related pathway in TBI is little to be known. We attempted to explore the significance of RIP3 in regulating TBI in vivo. Significantly, TBI induced over expression of RIP3 in the hippocampus of mice, as well as RIP1 and phosphorylated mixed lineage kinase domain-like protein (MLKL). Mice after TBI exhibited cognitive dysfunction and activation of glia cells, which were significantly attenuated by RIP3-knockout (KO). Moreover, inflammation and oxidative stress in hippocampus were markedly induced by TBI in wild type (WT) mice. Of note, the reduction of pro-inflammatory cytokines and oxidants was observed in RIP3 deficient mice, which was linked to the blockage of NLR pyrin domain containing 3 (NLRP3)/apoptosis-associated speck-like protein containing a CARD (ASC)/Caspase-1 and kelch-like ECH-associated protein 1 (Keap 1) pathways. Further, TBI induced hippocampus apoptosis, evidenced by the increase of cleaved Caspase-8/-3 and poly (ADP)-ribose polymerase (PARP) in WT mice, whereas being decreased by RIP3 knockout. In addition, RIP3 knockout led to phosphorylation of AMP-activated protein kinase alpha (AMPKalpha) in hippocampus of mice after TBI. And of note, the in vitro findings indicated that RIP3-ablation attenuated oxidative stress, inflammation and apoptosis in astrocytes, which was dependent on AMPKalpha activation. Together, suppressing RIP3 might be served as a therapeutic target against brain injury through inhibiting inflammation, oxidative stress and apoptosis. PMID- 29470983 TI - Development of a functional thyroid model based on an organoid culture system. AB - The low turnover rate of thyroid follicular cells and the lack of a long-term thyroid cell culture system have hampered studies of thyroid carcinogenesis. We have now established a thyroid organoid culture system that supports thyroid cell proliferation in vitro. The established mouse thyroid organoids performed thyroid functions including thyroglobulin synthesis, iodide uptake, and the production and release of thyroid hormone. Furthermore, transplantation of the organoids into recipient mice resulted in the formation of normal thyroid-like tissue capable of iodide uptake and thyroglobulin production in vivo. Finally, forced expression of oncogenic NRAS (NRASQ61R) in thyroid organoids established from p53 knockout mice and transplantation of the manipulated organoids into mouse recipients generated a model of poorly differentiated thyroid cancer. Our findings suggest that this newly developed thyroid organoid culture system is a potential research tool for the study of thyroid physiology and pathology including thyroid cancer. PMID- 29470984 TI - Ribosome biogenesis protein Urb2 regulates hematopoietic stem cells development via P53 pathway in zebrafish. AB - Ribosome biogenesis is a significant process in cells. Dysfunction in this process will result in the defects of protein synthesis and consequently cause the development of specific diseases called ribosomopathies. Mutations in ribosome biogenesis protein Rps19, Rpl5, or Rpl11 can lead to hematopoietic defects in human, thus triggering the disease Diamond Blackfan anemia. However, the regulatory mechanisms of ribosome biogenesis in hematopoiesis remain incompletely understood. In this study, we describe a zebrafish mutant cq42, which carries a nonsense mutation in the gene that encodes ribosome biogenesis 2 homolog (Urb2). Urb2 is strongly expressed in the caudal hematopoietic tissue (CHT) during hematopoietic stem cells (HSCs) expanding. Molecular characterization of urb2cq42 larvae suggest that urb2 deficiency notably decrease the population of HSCs in CHT and early T cells in thymus. Further analysis shows that compromised cell proliferation and superfluous apoptosis are observed in the CHT of urb2cq42 mutant. P53 pathway is upregulated in the urb2cq42 larvae and loss-of-function of P53 can fully rescue the hematopoietic defects in urb2cq42 mutant. These data demonstrate that urb2 is essential for HSCs development through the regulation of P53 pathway. PMID- 29470985 TI - Cytoplasmic p53 contributes to the removal of uracils misincorporated by HIV-1 reverse transcriptase. AB - HIV-1 reverse transcriptase (RT) in the cytoplasm of HIV-infected cells efficiently inserts the non-canonical dUTP into the proviral DNA, and extends the dU-terminated DNA. The misincorporation of dUTP leads to mutagenesis, and uracils can down-regulate viral gene expression. However, uracilation might also protect HIV DNA from auto-integration in the cytoplasm. Tumor suppressor p53 protein, exhibiting inherent 3'->5' exonuclease activity, provides a potential host derived repair mechanism during HIV reverse transcription for the misincorporation of various wrong nucleotides, leading to both base-base mismatches and incorporated non-canonical ribonucleotides. Since the presence of proofreading activity is essential for DNA synthesis accuracy, we elucidated the potential involvement of cytoplasmic p53 in the U-editing activities during insertion of dUTP into DNA by recombinant HIV-1 RT (using isogenic p53-proficient and -deficient HCT116 cells). The biochemical data show that p53 in cytoplasm can participate through the intermolecular pathway in a dU-damage-associated repair mechanism by its ability to remove preformed 3'-terminal dUs, thus preventing further extension of 3' dU-terminated primer during DNA synthesis by HIV-1 RT. The specific depletion of p53 from cytoplasmic lysates of repair-proficient p53 harboring cells reduced this negative effect. Accordingly, the increased abundance of p53 in nutlin-treated cells correlates with enhanced error correction functions, namely, removal of incorporated uracil. The data substantiate the significance of p53 as a potential proofreader for removal of non-canonical dUTP from HIV DNA, thus preventing the consequences of dUTP misincorporation in cell-type specific infectivity of HIV. PMID- 29470986 TI - Silencing of LncRNA-HOTAIR decreases drug resistance of Non-Small Cell Lung Cancer cells by inactivating autophagy via suppressing the phosphorylation of ULK1. AB - Drug resistance is an important factor leading to the recurrence and metastasis of Non-Small Cell Lung Cancer (NSCLC). Long non-coding RNAs (LncRNAs) play important roles in drug resistance of tumor cells. The aim of our study was to investigate the mechanism of LncRNA-HOTAIR in regulating drug resistance of NSCLC cells. Our data indicated that HOTAIR was overexpressed in NSCLC cell lines. Silencing of HOTAIR decreased cell proliferation and increased apoptosis of NSCLC cells (A549). Besides that, HOTAIR shRNA transfection suppressed drug resistance of A549 cells to Crizotinib by more effectively inhibiting cell viability and promoting apoptosis compared with HOTAIR scramble group. Moreover, silencing of HOTAIR decreased the number of LC3+ puncta and the expression of Beclin1, p-ULK1 and the ratio of LC3 II/I/in Crizotinib treated A549 cells, indicating that silencing of HOTAIR decreased drug resistance of NSCLC cells might through inhibiting autophagy via the ULK1 pathway. In order to further prove our conclusion, Rapamycin (Rapa), an autophagy inducer, was used in our study. With the adjunction of Rapa, obvious autophagy was induced by increasing the number of LC3+ puncta, the ratio of LC3 II/I and the expression of p-ULK1 compared with Crizotinib + HOTAIR shRNA group. What is more, the activation of autophagy abolished the effect of HOTAIR shRNA on decreasing drug resistance by increasing cell viability and decreasing cell apoptosis. These results supported our conclusion that silencing of HOTAIR decreased drug resistance of NSCLC cells to Crizotinib through inhibition of autophagy via suppressing phosphorylation of ULK1. PMID- 29470987 TI - Angiotensin-II regulates dosing time-dependent intratumoral accumulation of macromolecular drug formulations via 24-h blood pressure rhythm in tumor-bearing mice. AB - One approach to increasing pharmacotherapy effects is administering drugs at times of day when they are most effective and/or best tolerated. Circadian variation in expression of pharmacokinetics- and pharmacodynamics-related genes was shown to contribute to dosing time-dependent differences in therapeutic effects of small molecule drugs. However, influence of dosing time of day on effects of high molecular weight formulations, such as drugs encapsulated in liposomes, has not been studied in detail. This study demonstrates that blood pressure rhythm affects dosing time-dependent variation in effects of high molecular weight formulations. Systolic blood pressure in sarcoma 180-bearing mice showed significant 24-h oscillation. Intratumoral accumulation of fluorescein isothiocyanate-labeled bovine serum albumin (FITC-BSA), an indicator of tumor vascular permeability, varied with dosing time of day, matching phases of blood pressure circadian rhythm. Furthermore, intratumoral accumulation of liposome-encapsulated oxaliplatin (Lipo-L-OHP) increased with increases in systolic blood pressure. Our findings suggest that circadian blood pressure oscillations may be an important factor to consider in dosing strategies for macromolecular drugs and liposomes in cancer therapy. PMID- 29470988 TI - Shear-dependent fibrillogenesis of fibronectin: Impact of platelet integrins and actin cytoskeleton. AB - Soluble plasma fibronectin (Fn) with its inactive compact structure requires unfolding to assemble into active fibrils, which play a role in hemostasis and thrombosis. Fn fibril assembly involves Fn binding to cell receptors, biomechanical coupling of Fn to the cytoskeleton by integrins, exposure of self assembly sites via contractile cell forces, and elongation of fibrils by Fn polymerization. In this report, we investigated the effect of platelet integrins and actin cytoskeleton on conformational changes of Fn induced by shear. Plasma Fn, in the presence or absence of washed platelets, was exposed to dynamic shear simulating venous or arterial flow conditions. Platelet integrins (alphaIIbbeta3, alphavbeta3, and alpha5beta1) were blocked by inhibitory antibodies to determine their contribution to shear-induced Fn fibrillogenesis. To examine the role of platelet cytoskeleton in Fn fibrillogenesis induced by shear, platelets were preincubated with cytoskeleton drugs, i. e jasplakinolide to stabilize actin or cytochalasin D to inhibit actin polymerization. Microscopic analyses demonstrated that flow and resulting shear stress over a broad range of physiological and pathological rates (50-5000 s-1) could induce conformational changes of plasma Fn. In addition, the formation of Fn fibrils is modulated by platelet integrins. In this respect, beta3 integrins play a dominant role in terms of Fn fibrillogenesis induced by shear. Disruption of the actin polymerization markedly diminished Fn unfolding and assembly. These observations lead to the conclusion that Fn-integrin beta3-cytoskeleton interaction is crucial for the assembly of plasma Fn matrix under flow conditions. PMID- 29470989 TI - Redox exchange of the disulfides of human two-domain CD4 regulates the conformational dynamics of each domain, providing insight into its mechanisms of control. AB - CD4, a membrane glycoprotein expressed by specific leukocytes, plays a vital role in the human immune response and acts as a primary receptor for HIV entry. Of its four ecto-domains (D1-D4), D1, D2, and D4 each contain a distinctive disulfide bond. Whereas the disulfides of D1 and D4 are more traditional in nature, providing structural functions, that of D2 is referred to as an "allosteric" disulfide due to its high dihedral strain energy and relative ease of reduction that is thought to regulate CD4 structure and function by shuffling its redox state. While we have shown previously that elimination of the pre-stressed D2 disulfide results in a favorable structural collapse that increases the stability of a CD4 variant comprising only D1 and D2 (2dCD4), we sought to further localize and determine the nature of the biophysical modifications that take place upon redox exchange of the D1 and D2 disulfides by using amide hydrogen-deuterium exchange mass spectrometry (HDX-MS) to measure induced changes in conformational dynamics. By analyzing various redox isomers of 2dCD4, we demonstrate that ablation of the D1 disulfide enhances the dynamics of the domain considerably, with little effect on that of D2. Reduction of the D2 disulfide however decreases the conformational dynamics of many of the beta-strands of the domain that enclose the bond, suggesting a model in which inward collapse of secondary structure occurs around the allosteric disulfide upon its eradication, resulting in a marked decrease in hydrodynamic volume and increase in stability as previously described. Increases in the dynamics of regions important for HIV gp120 and MHCII binding in D1 also result allosterically after reducing the D2 disulfide, which are likely a consequence of the structural changes that take place in D2, findings that advance our understanding of the mechanisms by which redox exchange of the CD4 disulfides regulates its function. PMID- 29470991 TI - Modeling factors that regulate cell cooperativity in the zebrafish posterior lateral line primordium. AB - Collective cell migration is an integral part of organismal development. We consider migration of the zebrafish primordium during development of the posterior lateral line, a sensory system that detects water movement patterns. Experiments have shown that the chemokine ligand CXCL12a and its receptors CXCR4b and CXCR7b are key players for driving migration of the primordium, while FGF signaling helps maintain cohesion. In this work, we formulate a mathematical model of a laser ablated primordium separated into two smaller cell collectives: a leading collective that responds to local CXCL12a levels and a trailing collective that migrates up a local FGF gradient. Our model replicates recent experimental results, while also predicting a "runaway" behavior when FGF gradient response is inhibited. We also use our model to estimate diffusion coefficients of CXCL12a and FGF in the lateral line. PMID- 29470990 TI - Lis1 dysfunction leads to traction force reduction and cytoskeletal disorganization during cell migration. AB - Cell migration is a critical process during development, tissue repair, and cancer metastasis. It requires complex processes of cell adhesion, cytoskeletal dynamics, and force generation. Lis1 plays an important role in the migration of neurons, fibroblasts and other cell types, and is essential for normal development of the cerebral cortex. Mutations in human LIS1 gene cause classical lissencephaly (smooth brain), resulting from defects in neuronal migration. However, how Lis1 may affect force generation in migrating cells is still not fully understood. Using traction force microscopy (TFM) with live cell imaging to measure cellular traction force in migrating NIH3T3 cells, we showed that Lis1 knockdown (KD) by RNA interference (RNAi) caused reductions in cell migration and traction force against the extracellular matrix (ECM). Immunostaining of cytoskeletal components in Lis1 KD cells showed disorganization of microtubules and actin filaments. Interestingly, focal adhesions at the cell periphery were significantly reduced. These results suggest that Lis1 is important for cellular traction force generation through the regulation of cytoskeleton organization and focal adhesion formation in migrating cells. PMID- 29470992 TI - Control of cell fraction and population recovery during tissue regeneration in stem cell lineages. AB - Multicellular tissues are continually turning over, and homeostasis is maintained through regulated proliferation and differentiation of stem cells and progenitors. Following tissue injury, a dramatic increase in cell proliferation is commonly observed, resulting in rapid restoration of tissue size. This regulation is thought to occur via multiple feedback loops acting on cell self renewal or differentiation. Models of ordinary differential equations have been widely used to study the cell lineage system. Prior modeling studies have suggested that loss of homeostasis and initiation of tumorigenesis can be contributed to the loss of control of these processes, and the rate of symmetric versus asymmetric division of the stem cells may also be altered. While most of the previous works focused on analysis of stability, existence and uniqueness of steady states of multistage cell lineage models, in this work we attempt to understand the cell lineage model from a different perspective. We compare three variants of hierarchical stem cell lineage tissue models with different combinations of negative feedbacks and use sensitivity analysis to examine the possible strategies for the cells to achieve certain performance objectives. Our results suggest that multiple negative feedback loops must be present in the stem cell lineage to keep the fractions of stem cells to differentiated cells in the total population as robust as possible to variations in cell division parameters, and to minimize the time for tissue recovery in a non-oscillatory manner. PMID- 29470993 TI - Stress: Common themes toward the next frontier. AB - "Stress is complicated". A phrase uttered by many a stress researcher. This is true, from the vast array of stimuli considered "stressors" to the interactive and hormetic nature of the molecular, cellular, endocrine, and behavioral responses generated by such stressors. This commentary takes the position that stress researchers are poised to make even bigger contributions if they begin to shift from investigating the myriad effects of stress on brain and body, and to refocus a larger part of our efforts on more in-depth investigations of common themes in stress biology, with the goal of uncovering potential "universal principles" of stress that may help us better interpret the findings at higher levels of analysis, and provide a structured approach to help breach the next frontiers of stress research. PMID- 29470994 TI - A virus-like particle vaccine protects mice against coxsackievirus A10 lethal infection. AB - Coxsackievirus A10 (CVA10) has emerged worldwide as one of the main pathogens of hand, foot, and mouth disease (HFMD) in recent years. However, there is currently no commercial vaccine available to prevent CVA10 infection. Here we report the development of a recombinant virus-like particle (VLP) based candidate vaccine for CVA10. Co-expression of the capsid protein precursor P1 and the protease 3CD of CVA10 in Pichia pastoris resulted in cleavage of P1 into three capsid subunit proteins VP0, VP1, and VP3. These three subunit proteins co-assembled into CVA10 VLPs, which were visualized as spherical particles with a diameter of ~30 nm under electron microscope. Immunization studies showed that CVA10 VLP could efficiently induce antigen-specific serum antibodies in mice. The anti-VLP sera were able to potently neutralize homologous and heterologous CVA10 strains. Importantly, passively transferred anti-VLP sera fully protected recipient neonatal mice from lethal CVA10 infection. In addition, neonatal mice born to the VLP-immunized dams were also completely protected from CVA10 lethal challenge. Collectively, these data show that CVA10 VLP represents a promising CVA10 vaccine candidate. PMID- 29470995 TI - RACK1/TRAF2 regulation of modulator of apoptosis-1 (MOAP-1). AB - MOAP-1 is a pro-apoptotic tumor suppressor molecule with a growing set of known interacting partners. We have demonstrated that during death receptor-dependent apoptosis, MOAP-1 is recruited to TNF-R1 or TRAIL-R1, followed by RASSF1A and Bax association. MOAP-1/Bax association promotes Bax conformational change resulting in the translocation of Bax into the mitochondrial membrane, mitochondrial membrane insertion and dysregulation resulting in several hallmark events that execute apoptosis. Although a role in apoptosis is established, it is currently unknown how MOAP-1 is regulated and how it links to Bax to promote apoptosis. In this study, we demonstrate robust association with RACK1, a versatile scaffolding protein that responds to activation of protein kinase C. Furthermore, we can demonstrate that RACK1 functions to bring the E3 ligase, TRAF2, to MOAP-1 in order to undergo a K63-dependent ubiquitination. Furthermore, RACK1 associates with MOAP-1 via electrostatic associations similar to those observed between MOAP 1/RASSF1A and MOAP-1/TNF-R1. These events illustrate the complex nature of MOAP-1 regulation and characterizes the important role of the scaffolding protein, RACK1, in influencing MOAP-1 biology.

AB - OBJECTIVE: The aim of our study was to detect functional changes in default-mode network of neuromyelitis optica (NMO) patients using resting-state functional magnetic resonance images and the evaluation of subcortical gray-matter structures volumes. MATERIALS AND METHODS: NMO patients (n=28) and controls patients (n=19) were enrolled. We used the integrated registration and segmentation tool, part of FMRIB's Software Library (FSL) to segment subcortical structures including the thalamus, caudate nucleus, putamen, hippocampus and amygdalae. Resting-state functional magnetic resonance images were post-processed using the Multivariate Exploratory Linear Optimized Decomposition into Independent Components, also part of FSL. Average Z-values extracted from the default-mode network were compared between patients and controls using t-tests (P values <0.05 were considered statistically significant). RESULTS: There were areas of increased synchronization in the default-mode network of patients compared to controls, notably in the precuneus and right hippocampus (corrected P<0.01). The frontal area had decreased synchronization in patients compared to controls (corrected P<0.01). There were no observed differences between patients and controls in subcortical volumes or average Z-values values for default-mode network. CONCLUSION: The hyperactivity of certain default-mode network areas may reflect cortical compensation for subtle structural damage in NMO patients.

AB - INTRODUCTION: Mechanical thrombectomy for anterior circulation large vessel occlusion (LVO) improves functional outcome at three months. This therapeutic approach is the new gold standard, with a benefit being also observed in elderly patients. However, data are limited in this heterogeneous and fragile population. The objectives of this study were, first, to describe outcome after mechanical thrombectomy in a representative group of patients over 80. Second, to evaluate factors associated with a favorable functional outcome after thrombectomy for anterior circulation LVO in elderly patients (aged>=80 years). METHODS: A total of 169 patients with anterior circulation LVO referred for an endovascular treatment were included. Primary outcome evaluated functional outcome at three months. Multivariable analysis was performed to identify prognostic factors in elderly patients with pre-stroke mRS<=3. RESULTS: Overall, 25.34% of patients (43/169) were functionally independent at three months (mRS<=2) and 16.57% (28/169) had a moderate functional disability (mRS=3). Mortality rate was 33.14% (56/169). At 24h, 7.1% of patients (12/169) had symptomatic hemorrhage. Male gender (P=0.033), low initial NIHSS (P=0.037), higher DWI-ASPECTS (P=0.022) and use of intravenous thrombolysis (IVT) (P=0.0193) were associated with a better functional outcome. CONCLUSIONS: There is no reason to withhold mechanical thrombectomy on the basis of age alone. Small infarct core, low NIHSS, male gender and use of IVT are associated with a better functional outcome. PMID- 29470998 TI - Evaluation of a New Design of Antireflux-biodegradable Ureteral Stent in Animal Model. AB - OBJECTIVE: To determine the effects in urinary tract of a new antireflux biodegradable ureteral stent. MATERIALS AND METHODS: Thirty six ureters belonging to 24 pigs were used. The study began with endoscopic, nephrosonographic, and fluoroscopic assessments. Three study groups of ureters (n = 12) were then specified. In group I, a biodegradable antireflux ureteral stent (BDG-ARS) was inserted in the right ureter of 12 pigs. Group II comprised the left ureter of the same animals, in which a double-pigtail stent was placed for 6 weeks. Group III ureters, belonging to 12 additional animals, were subjected to a ureteropelvic junction obstruction model that was then treated by endopyelotomy and stenting with BDG-ARS. Follow-ups were performed at 3-6 weeks and at 5 months. RESULTS: None of the ureters receiving the BDG-ARS showed any evidence of vesicoureteral reflux (VUR). BDG-ARS degradation took place in a controlled and predictable fashion from the third to the sixth weeks, and no obstructive fragments appeared. No differences were found between groups I and II regarding passive ureteral dilation, but significant differences were found regarding VUR and ureteral orifice damage. BDG-ARS always maintained distal ureteral peristalsis. BDG-ARS in group III showed a 50% positive urine culture rate and a 16.6% migration rate in both BDG-ARS groups. CONCLUSION: BDG-ARS avoided VUR and bladder trigone irritation. In addition, this polymer combination and stent braided design achieved a consistent biodegradation rate with no obstructive fragments and with uniform degradation between the third and the sixth weeks. Consequently, morbidity associated with ureteral stents might be reduced. PMID- 29470999 TI - Mast cells regulate CD4+ T-cell differentiation in the absence of antigen presentation. AB - BACKGROUND: Given their unique capacity for antigen uptake, processing, and presentation, antigen-presenting cells (APCs) are critical for initiating and regulating innate and adaptive immune responses. We have previously shown the role of nicotinamide adenine dinucleotide (NAD+) in T-cell differentiation independently of the cytokine milieu, whereas the precise mechanisms remained unknown. OBJECTIVE: The objective of this study is to further dissect the mechanism of actions of NAD+ and determine the effect of APCs on NAD+-mediated T cell activation. METHODS: Isolated dendritic cells and bone marrow-derived mast cells (MCs) were used to characterize the mechanisms of action of NAD+ on CD4+ T cell fate in vitro. Furthermore, NAD+-mediated CD4+ T-cell differentiation was investigated in vivo by using wild-type C57BL/6, MC-/-, MHC class II-/-, Wiskott Aldrich syndrome protein (WASP)-/-, 5C.C7 recombination-activating gene 2 (Rag2) /-, and CD11b-DTR transgenic mice. Finally, we tested the physiologic effect of NAD+ on the systemic immune response in the context of Listeria monocytogenes infection. RESULTS: Our in vivo and in vitro findings indicate that after NAD+ administration, MCs exclusively promote CD4+ T-cell differentiation, both in the absence of antigen and independently of major APCs. Moreover, we found that MCs mediated CD4+ T-cell differentiation independently of MHC II and T-cell receptor signaling machinery. More importantly, although treatment with NAD+ resulted in decreased MHC II expression on CD11c+ cells, MC-mediated CD4+ T-cell differentiation rendered mice resistant to administration of lethal doses of L monocytogenes. CONCLUSIONS: Collectively, our study unravels a novel cellular and molecular pathway that regulates innate and adaptive immunity through MCs exclusively and underscores the therapeutic potential of NAD+ in the context of primary immunodeficiencies and antimicrobial resistance. PMID- 29471000 TI - Relationship between cerebrospinal fluid concentrations of orexin A/hypocretin-1 and body composition in humans. AB - The hypothalamic neuropeptide orexin A (hypocretin-1) is a key signal in sleep/wake regulation and promotes food intake. We investigated the relationship between cerebrospinal fluid orexin A concentrations and body composition in non narcoleptic human subjects with a wide range of body weight to gain insight into the role of orexin A in human metabolism. We collected cerebrospinal fluid and blood samples and measured body composition by bioelectric impedance analysis in 36 subjects (16 women and 20 men) with body mass indices between 16.24 and 38.10 kg/m2 and an age range of 19-80 years. Bivariate Pearson correlations and stepwise multiple regressions were calculated to determine associations between orexin A and body composition as well as biometric variables. Concentrations of orexin A in cerebrospinal fluid averaged 315.6 +/- 6.0 pg/ml, were comparable between sexes (p > 0.15) and unrelated to age (p > 0.66); they appeared slightly reduced in overweight/obese compared to normal-weight subjects (p = .07). Orexin A concentrations decreased with body weight (r = -0.38, p = .0229) and fat-free mass (r = -0.39, p = .0173) but were not linked to body fat mass (p > 0.24). They were inversely related to total body water (r = -0.39, p = .0174) as well as intracellular (r = -0.41, p = .0139) and extracellular water (r = -0.35, p = .0341). Intracellular water was the only factor independently associated with cerebrospinal fluid orexin A concentrations (p = .0139). We conclude that cerebrospinal fluid orexin A concentrations do not display associations with body adiposity, but are inversely related to intracellular water content. These cross sectional findings suggest a link between orexin A signaling and the regulation of water homeostasis in humans. PMID- 29471001 TI - Activated CXCL5-CXCR2 axis promotes the migration, invasion and EMT of papillary thyroid carcinoma cells via modulation of beta-catenin pathway. AB - Initiation of epithelial-to-mesenchymal transition (EMT) is common in papillary thyroid carcinoma (PTC) and may contribute to its metastasis. Aims of the present study are to investigate whether and how the C-X-C motif chemokine ligand (CXCL) 5/C-X-C motif receptor 2 (CXCR2) axis affects PTC metastasis, with a focus on the EMT process. Herein, two PTC cell lines, KTC-1 and B-CPAP cells, identified as CXCR2-positive cells were used as the cell model. We found that a 24-h stimulation of 1 or 10 nM recombinant human CXCL5 (rhCXCL5) enhanced the migration and invasion of both KTC-1 and B-CPAP cells without affecting their proliferation. The migration- and invasion-promoting effects of rhCXCL5 were attenuated if CXCR2 was silenced by its specific short hairpin RNAs (shRNAs). EMT initiation is defined as downregulation of epithelial-cadherin (E-cadherin) and upregulation of N-cadherin, Vimentin and Snail. Our data showed that rhCXCL5 induced EMT in PTC cells was suppressed by CXCR2 shRNA. Furthermore, the active CXCL5-CXCR2 axis enhanced the phosphorylation of Akt at Ser 473 residue and that of glycogen synthase kinase-3 (GSK-3beta) at Ser 9 residue, and accelerated the nuclear accumulation of beta-catenin in PTC cells. Re-expression of the active form of beta-catenin in PTC cells rescued their impaired invasiveness caused by the blockade of CXCL5-CXCR2 axis. In addition, CXCL5 and CXCR2 were overexpressed in the metastatic lymph nodes obtained from 18 patients with PTC. In summary, our study demonstrates that the activated CXCL5-CXCR2 axis contributes to the metastatic phenotype of PTC cells by modulating Akt/GSK-3beta/beta-catenin pathway. PMID- 29471002 TI - Interpersonal relationship modulates the behavioral and neural responses during moral decision-making. AB - Interpersonal relationship (IR) may play an important role in moral decision making. However, it is little known about how IR influences neural and behavioral responses during moral decision-making. The present study utilized the dilemma scenario-priming paradigm to examine the time course of the different intimate IR (friend, acquaintance, or stranger) impacts on the emotional and cognitive processes during moral decision-making. Results showed that participants made less altruistic decisions with increased decision times and experienced more unpleasure for strangers versus friends and acquaintances. Moreover, at the early moral intuitional process, there was no significance difference observed at N1 under different intimate IR; however, at the emotional process, larger P260 which reflects the dilemma conflicts and negative emotional responses, was elicited when moral decision-making for strangers; at the later cognitive process, such difference was also observed at LPP (300-450 ms) which indexes the later top-down cognitive appraisal and reasoning processes. However, such differences were not observed between friends and acquaintances. Results indicate that IR modulates the emotional and cognitive processes during moral decision-making, suggesting that the closer the IR is, the weaker the dilemma conflicts and emotional responses are, and the more efficient this conflicts are solved. PMID- 29471003 TI - TrkB receptor antagonism inhibits stab injury induced proliferative response in adult zebrafish (Danio rerio) brain. AB - The Tropomyosin related kinase B (TrkB) receptor, is known to promote neuronal maturation, differentiation, maintenance and survival through its cognate ligands Brain derived neurotrophic factor (BDNF) and neurotrophin 4 (NT4). BDNF, NT4 and TrkB are highly conserved proteins among vertebrates. Although the role of TrkB during brain development is well established, its role in adult neurogenesis and brain regeneration awaits thorough investigation. In this study, we used the zebrafish stab wound injury model to determine whether the injury induced regeneration response in the telencephalon region is governed by TrkB or not. We induced stab wound injury in the mid-dorsal region of telencephalon of ANA-12 (selective TrkB antagonist) treated and non-treated zebrafish brain and examined the proliferation activity in selected brain regions using immunohistochemistry. We found that proliferation activity was significantly low in ANA-12 injected injured fishes as compared to vehicle control injured fishes. Other major findings of the study include the temporal pattern of proliferation activity after an injury and activation of adult neural stem cells (aNSCs) situated distantly apart from the injury site in the adult zebrafish brain. PMID- 29471005 TI - MiR-155-5p controls colon cancer cell migration via post-transcriptional regulation of Human Antigen R (HuR). AB - Colorectal cancer (CRC) is the third most common cancer and a significant cause of cancer-related deaths worldwide. Metastasis is the worst prognostic factor for patients with CRC. HuR (ELAVL1) is overexpressed in CRC and has been reported to promote colon cancer growth by targeting RNA in the cell cytoplasm. Herein, the role of miR-155-5p in regulating HuR expression and cell migration was examined in colon cancer cells. MiR-155-5p knockdown in serum-starved colon cancer cells decreased both colon cancer cell chemotaxis and cytoplasmic expression of HuR. Bioinformatics analysis predicted two putative binding sites in the AU-rich elements (AREs) at the 3'-UTR of HuR mRNA. MiR-155-5p binding to HuR was verified using specific target site blockers and functionally validated by use of RNA immunoprecipitation assays, showing that miR-155-5p-dependent regulation of HuR expression is mediated by AREs. Targeting AREs with a specific blocker inhibited colon cancer cell migration. Taken together, these novel findings demonstrate that AREs mediate miR-155-5p positive regulation of HuR mRNA levels and translation as well as migration in colon cancer cells, suggesting that targeting miR-155-5p and/or Hur might be useful therapeutic strategies against colon cancer metastasis. PMID- 29471004 TI - Prostate cancer chemoprevention by natural agents: Clinical evidence and potential implications. AB - Prostate cancer (PCa) is the most common non-skin cancer and the second leading cause of cancer-related deaths in American men. Due to its long latency period, PCa is considered as an ideal cancer type for chemopreventive interventions. Chemopreventive agents include various natural or synthetic agents that prevent or delay cancer development, progression and/or recurrence. Pre-clinical studies suggest that many natural products and dietary agents have chemopreventive properties. However, a limited number of these agents have been tested in clinical trials, with varying success. In this review, we have discussed the available clinical studies regarding the efficacy of natural chemopreventive agents against PCa, including tea polyphenols, selenium, soy proteins, vitamins and resveratrol. We have also provided a discussion on the clinical challenges and opportunities for the potential use of chemopreventive agents against PCa. Based on available literature, it appears that the variable outcomes of the chemopreventive clinical studies necessitate a need for additional studies with more rigorous designs and methodical interpretations in order to measure the potential of the natural agents against PCa. PMID- 29471006 TI - Astilbin ameliorates cisplatin-induced nephrotoxicity through reducing oxidative stress and inflammation. AB - Oxidative stress and inflammation are considered to be the main pathogenesis of cisplatin nephrotoxicity. Astilbin, a flavonoid with anti-oxidation and anti inflammation function, has been used to treat heavy metal induced kidney injury. In this study, we investigated the protective effects of astilbin on cisplatin induced nephrotoxicity and its underlying mechanisms. Our results showed that astilbin markedly inhibited cisplatin-induced cell apoptosis and recovered cell growth. Astilbin significantly decreased reactive oxygen species (ROS) accumulation and alleviated ROS-induced activation of p53, MAPKs and AKT signaling cascades, which in turn attenuated cisplatin-induced HEK-293 cell apoptosis. Astilbin effectively enhanced NRF2 activation and transcription of its targeting antioxidant genes to reduce ROS accumulation in cisplatin-induced HEK 293 cells. Furthermore, we found that astilbin obviously suppressed tumor necrosis factor alpha (TNF-alpha) expression and NF-kappaB activation, and also inhibited the expression of induced nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2). Finally, we confirmed that the effect of astilbin to improve renal oxidative stress and inflammation in cisplatin induced acute nephrotoxic mice. In conclusion, our study suggests that astilbin could ameliorate the cisplatin-induced nephrotoxicity by reducing oxidative stress and inflammation. PMID- 29471007 TI - Risk assessment of benzene in food samples of Iran's market. AB - The concentration of benzene in ninety-eight collected food and drink samples (carbonated beverage, fruit juice, pickle, lime juice, mayonnaise and salad dressing, 16 samples from each) from Iran local markets were investigated using gas chromatography equipped with flame ionization detector (GC-FID). Moreover, the correlation of benzene concentration with sodium benzoate and ascorbic acid concentrations was assessed. Benzene concentration in carbonated beverages, fruit juices, pickle, lime juices, mayonnaise and salad dressing were 3.57 +/- 1.70, 5.17 +/- 3.63, 4.37 +/- 2.24, 4.99 +/- 0.54, 1.38 +/- 0.87 and 1.47 +/- 0.83 MUg/L, respectively, being in all cases below the acceptable limit (10 MUg/L) proposed by the World Health Organization (WHO) as a reference for drinking water. Benzene concentration exceeded the maximum tolerable limit in 12.5% of carbonated beverages and fruit juices (two samples from each). A significant correlation coefficient between the concentrations of benzene, sodium benzoate, and ascorbic acid in fruit juices, and levels of benzene, sodium benzoate in carbonated beverage samples was observed. To characterize the risk of exposure of urban and rural consumers of Iran (female in age group of 15-24 and male in age group of 25-64) to benzene in food and drink samples the Margin of Exposure (MoE) approach was applied revealing there is no severe concern regarding benzene intake through assessed food and beverages samples in Iran. PMID- 29471008 TI - The chain of survival: Not all links are equal. AB - The chain of survival aims to demonstrate the interrelationship between key stages of resuscitation and emphasises the need for all links to be effective in order to optimise the chances of survival. The contribution of each of the four links diminishes rapidly as patients succumb at each stage and the actual attrition rate results in rapidly decreasing numbers of patients progressing along the chain. This revised representation adjusts the area of each link in order to graphically represent the flow of patients through the chain. Greatest benefit in improving outcome will be achieved by focussing on improving care at links in the chain where there is the greatest number of patients. PMID- 29471009 TI - Patterns induced by super cross-diffusion in a predator-prey system with Michaelis-Menten type harvesting. AB - Turing instability and pattern formation in a super cross-diffusion predator-prey system with Michaelis-Menten type predator harvesting are investigated. Stability of equilibrium points is first explored with or without super cross-diffusion. It is found that cross-diffusion could induce instability of equilibria. To further derive the conditions of Turing instability, the linear stability analysis is carried out. From theoretical analysis, note that cross-diffusion is the key mechanism for the formation of spatial patterns. By taking cross-diffusion rate as bifurcation parameter, we derive amplitude equations near the Turing bifurcation point for the excited modes by means of weakly nonlinear theory. Dynamical analysis of the amplitude equations interprets the structural transitions and stability of various forms of Turing patterns. Furthermore, the theoretical results are illustrated via numerical simulations. PMID- 29471010 TI - Phylogenetic diversity and biodiversity indices on phylogenetic networks. AB - In biodiversity conservation it is often necessary to prioritize the species to conserve. Existing approaches to prioritization, e.g. the Fair Proportion Index and the Shapley Value, are based on phylogenetic trees and rank species according to their contribution to overall phylogenetic diversity. However, in many cases evolution is not treelike and thus, phylogenetic networks have been developed as a generalization of phylogenetic trees, allowing for the representation of non treelike evolutionary events, such as hybridization. Here, we extend the concepts of phylogenetic diversity and phylogenetic diversity indices from phylogenetic trees to phylogenetic networks. On the one hand, we consider the treelike content of a phylogenetic network, e.g. the (multi)set of phylogenetic trees displayed by a network and the so-called lowest stable ancestor tree associated with it. On the other hand, we derive the phylogenetic diversity of subsets of taxa and biodiversity indices directly from the internal structure of the network. We consider both approaches that are independent of so-called inheritance probabilities as well as approaches that explicitly incorporate these probabilities. Furthermore, we introduce our software package NetDiversity, which is implemented in Perl and allows for the calculation of all generalized measures of phylogenetic diversity and generalized phylogenetic diversity indices established in this note that are independent of inheritance probabilities. We apply our methods to a phylogenetic network representing the evolutionary relationships among swordtails and platyfishes (Xiphophorus: Poeciliidae), a group of species characterized by widespread hybridization. PMID- 29471011 TI - Gaussian process approximations for fast inference from infectious disease data. AB - We present a flexible framework for deriving and quantifying the accuracy of Gaussian process approximations to non-linear stochastic individual-based models of epidemics. We develop this for the SIR and SEIR models, and we show how it can be used to perform quick maximum likelihood inference for the underlying parameters given population estimates of the number of infecteds or cases at given time points. We also show how the unobserved processes can be inferred at the same time as the underlying parameters. PMID- 29471012 TI - Paediatric fatty liver disease (PeFLD): All is not NAFLD - Pathophysiological insights and approach to management. AB - The recognition of a pattern of steatotic liver injury where histology mimicked alcoholic liver disease, but alcohol consumption was denied, led to the identification of non-alcoholic fatty liver disease (NAFLD). Non-alcoholic fatty liver disease has since become the most common chronic liver disease in adults owing to the global epidemic of obesity. However, in paediatrics, the term NAFLD seems incongruous: alcohol consumption is largely not a factor and inherited metabolic disorders can mimic or co-exist with a diagnosis of NAFLD. The term paediatric fatty liver disease may be more appropriate. In this article, we summarise the known causes of steatosis in children according to their typical, clinical presentation: i) acute liver failure; ii) neonatal or infantile jaundice; iii) hepatomegaly, splenomegaly or hepatosplenomegaly; iv) developmental delay/psychomotor retardation and perhaps most commonly; v) the asymptomatic child with incidental discovery of abnormal liver enzymes. We offer this model as a means to provide pathophysiological insights and an approach to management of the ever more complex subject of fatty liver. PMID- 29471013 TI - Hepatic arterial infusion of oxaliplatin plus fluorouracil/leucovorin vs. sorafenib for advanced hepatocellular carcinoma. AB - BACKGROUND & AIMS: To compare the overall survival (OS) and disease progression free survival (PFS) in patients with advanced hepatocellular carcinoma (Ad-HCC) who are undergoing hepatic arterial infusion (HAI) of oxaliplatin, fluorouracil/leucovorin (FOLFOX) treatment vs. sorafenib. METHODS: This retrospective study was approved by the ethical review committee, and informed consent was obtained from all patients before treatment. HAI of FOLFOX (HAIF) was recommended as an alternative treatment option for patients who refused sorafenib. Of the 412 patients with Ad-HCC (376 men and 36 women) between Jan 2012 to Dec 2015, 232 patients were treated with sorafenib; 180 patients were given HAIF therapy. The median age was 51 years (range, 16-82 years). Propensity score matched estimates were used to reduce bias when evaluating survival. Survival curves were calculated by performing the Kaplan-Meier method and compared by using the log-rank test and Cox regression models. RESULTS: The median PFS and OS in the HAIF group were significantly longer than those in the sorafenib group (PFS 7.1 vs. 3.3 months [RECIST]/7.4 vs. 3.6 months [mRECIST], respectively; OS 14.5 vs. 7.0 months; p <0.001 for each). In the propensity-score matched cohorts (147 pairs), both PFS and OS in the HAIF group were longer than those in the sorafenib group (p <0.001). At multivariate analysis, HAIF treatment was an independent factor for PFS (hazard ratio [HR] 0.389 [RECIST]/0.402 [mRECIST]; p <0.001 for each) and OS (HR 0.129; p <0.001). CONCLUSION: HAIF therapy may improve survival compared to sorafenib in patients with Ad-HCC. A prospective randomized trial is ongoing to confirm this finding. LAY SUMMARY: We compared the hepatic arterial infusion of FOLFOX (a combination chemotherapy) with sorafenib (a tyrosine kinase inhibitor) in patients with advanced hepatocellular carcinoma, retrospectively. It was found that hepatic arterial infusion of FOLFOX therapy may improve both progression free and overall survival in patients with advanced hepatocellular carcinoma. PMID- 29471014 TI - Epigenomic drugs and the germline: Collateral damage in the home of heritability? AB - The testis and ovary provide specialised environments that nurture germ cells and facilitate their maturation, culminating in the production of mature gametes that can found the following generation. The sperm and egg not only transmit genetic information, but also epigenetic modifications that affect the development and physiology of offspring. Importantly, the epigenetic information contained in mature sperm and oocytes can be influenced by a range of environmental factors, such as diet, chemicals and drugs. An increasing range of studies are revealing how gene-environment interactions are mediated through the germline. Outside the germline, altered epigenetic state is common in a range of diseases, including many cancers. As epigenetic modifications are reversible, pharmaceuticals that directly target epigenetic modifying proteins have been developed and are delivering substantial benefits to patients, particularly in oncology. While providing the most effective patient treatment is clearly the primary concern, some patients will want to conceive children after treatment. However, the impacts of epigenomic drugs on the male and female gametes are poorly understood and whether these drugs will have lasting effects on patients' germline epigenome and subsequent offspring remains largely undetermined. Currently, evidence based clinical guidelines for use of epigenomic drugs in patients of reproductive age are limited in this context. Developing a deeper understanding of the epigenetic mechanisms regulating the germline epigenome and its impact on inherited traits and disease susceptibility is required to determine how specific epigenomic drugs might affect the germline and inheritance. Understanding these potential effects will facilitate the development of informed clinical guidelines appropriate for the use of epigenomic drugs in patients of reproductive age, ultimately improving the safety of these therapies in the clinic. PMID- 29471015 TI - Biological profiling of plasma neuropeptide Y in relation to posttraumatic stress symptoms in two combat cohorts. AB - In order to decrease the risk of developing stress-related disorders after military deployment, biological vulnerability factors should be identified. Neuropeptide Y (NPY) is a peptide neurotransmitter that is associated with modulation of the stress response. Using the data of two longitudinal prospective cohort studies (N = 892 and N = 2427), plasma NPY (pNPY) was assessed as a possible susceptibility biomarker for the development of PTSD symptoms over time. Data collection started prior to deployment and follow-up assessments were completed up to two years after deployment. In pNPY levels, measured before and shortly after deployment, three distinct trajectories were identified. In both cohorts, these trajectories were not related to the level of reported PTSD symptoms over time and neither were pre-deployment pNPY levels. Whereas previous research suggested that high NPY levels might be a marker for resilience, the current findings suggest limited usefulness of peripherally measured NPY in the development of PTSD. PMID- 29471016 TI - Sensitivity to psychosocial chronic stressors and adolescents' externalizing problems: Combined moderator effects of resting heart rate and parental psychiatric history. AB - From the literature it is not clear whether low resting heart rate (HR) reflects low or high sensitivity to the detrimental effects of adverse environments on externalizing problems. We studied parental psychiatric history (PH), reflecting general vulnerability, as possible moderator explaining these inconsistencies. Using Linear Mixed Models, we analyzed data from 1914 subjects, obtained in three measurement waves (mean age 11, 13.5, and 16 years) from the TRacking Adolescents' Individual Lives Survey population-based cohort and the parallel clinic-referred cohort. As hypothesized, more chronic stressors predicted more externalizing problems in vulnerable individuals with high resting HR but not in those with low resting HR, suggesting high vs. low sensitivity, respectively, to adverse environmental influences. Low sensitivity to adverse environmental influences in vulnerable individuals exposed to high stressor levels was additionally confirmed by high heart rate variability (Root Mean Squared Successive Difference; RMSSD). In adolescents with low vulnerability, in contrast, the association between chronic stressors and externalizing problems did not substantially differ by resting HR and RMSSD. Future research may demonstrate whether our findings extend to other adverse, or beneficial, influences. Notwithstanding their theoretical interest, the effects were small, only pertained to parent-reported externalizing problems, refer to a small subset of respondents in our sample, and are in need of replication. We conclude that HR and RMSSD are unlikely to be strong moderators of the association between stressors and externalizing problems. PMID- 29471017 TI - Moderate effects of noninvasive brain stimulation of the frontal cortex for improving negative symptoms in schizophrenia: Meta-analysis of controlled trials. AB - BACKGROUND: Negative symptoms in schizophrenia concern a clinically relevant reduction of goal-directed behavior that strongly and negatively impacts daily functioning. Existing treatments are of marginal effect and novel approaches are needed. Noninvasive neurostimulation by means of repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS) are novel approaches that may hold promise. OBJECTIVES: To provide a quantitative integration of the published evidence regarding effects of rTMS and tDCS over the frontal cortex on negative symptoms, including an analysis of effects of sham stimulation. METHODS: Meta-analysis was applied, using a random effects model, to calculate mean weighted effect sizes (Cohen's d). Heterogeneity was assessed by using Cochrans Q and I2 tests. RESULTS: For rTMS treatment, the mean weighted effect size compared to sham stimulation was 0.64 (0.32-0.96; k = 22, total N = 827). Studies with younger participants showed stronger effects as compared to studies with older participants. For tDCS studies a mean weighted effect size of 0.50 (-0.07 to 1.07; k = 5, total N = 134) was found. For all frontal noninvasive neurostimulation studies together (i.e., TMS and tDCS studies combined) active stimulation was superior to sham, the mean weighted effect size was 0.61 (24 studies, 27 comparisons, 95% confidence interval 0.33-0.89; total N = 961). Sham rTMS (baseline - posttreatment comparison) showed a significant improvement of negative symptoms, d = 0.31 (0.09-0.52; k = 16, total N = 333). Whereas previous meta-analyses were underpowered, our meta-analysis had a power of 0.87 to detect a small effect. CONCLUSIONS: The available evidence indicates that noninvasive prefrontal neurostimulation can improve negative symptoms. This finding suggests a causal role for the lateral frontal cortex in self-initiated goal-directed behavior. The evidence is stronger for rTMS than for tDCS, although this may be due to the small number of studies as yet with tDCS. More research is needed to establish moderator variables that may affect response to neurostimulation and to optimize treatment parameters in order to achieve stable and durable (and thus clinically relevant) effects. PMID- 29471018 TI - Rotenone induces gastrointestinal pathology and microbiota alterations in a rat model of Parkinson's disease. AB - While people are often aware of the motor symptoms in Parkinson's disease (PD), few know of the many non-motor symptoms, which patients report have a greater impact on their quality of life. Gastrointestinal (GI) dysfunction is one of the most common non-motor symptoms, which can occur at any stage of PD, even years prior to diagnosis, and can affect all sections along the GI tract causing a range of symptoms including drooling, gastroparesis and constipation. We have investigated whether a neurotoxin model of PD induced by rotenone, a mitochondrial complex I inhibitor, is capable of reproducing the GI dysfunction seen clinically. Sprague-Dawley rats were administered 2.75 mg/kg rotenone, 5 days/week for 4 weeks, via intraperitoneal injection. Rats underwent behavioural testing, including the one-hour stool and gastric emptying tests before GI contents and tissues were collected for microbiota and histological analysis. Rats exposed to rotenone had more days with evidence of diarrhoea and significantly delayed gastric emptying, reproducing the clinical symptom of gastroparesis. Microbiota analysis revealed alterations in the small intestine and colon of rotenone-treated rats, relatively consistent with changes described in PD patients. Histological analysis demonstrated mucosal thickening and goblet cell hyperplasia in the colon of rotenone rats, which may be an adaptive response to the toxin or changes in GI microbiota. Our results indicate that rotenone may be a good model for investigating the mechanisms involved with Parkinson's GI symptoms and for screening potential therapeutic options as it is capable of recapitulating some key GI changes that occur during PD progression.

AB - INTRODUCTION: A variety of in vitro tests to replace the Draize test have been developed; however, there is no available method for assessing the full spectrum of Globally Harmonized System (GHS) categories. Human cornea-like three dimensional (3D) reconstructed tissue models are the most promising in vitro systems. The objective of this study was to evaluate the ocular toxicity of 11 test substances using the EpiOcularTM model after performing proficiency tests. We further evaluated the effectiveness of ezrin staining as a complementary marker in histological analysis to overcome the limitation of eye irritation tests using 3D reconstructed human corneal epithelium models. METHODS: The assessment of ocular toxicity was performed by the suggested OECD TG 492 procedure. After treatment with proficiency test chemicals and 10 test substances, EpiOcularTM tissue models were stained with hematoxylin and eosin and ezrin, and the histological changes were observed by immunofluorescence microscopy. RESULTS: The ocular toxicity assessment of 10 test chemicals using the EpiOcularTM eye irritation test were in accordance with the UN GHS classification of test chemicals. Histological analysis of ezrin staining showed that the cell membranes of models treated with 10 out of 11 non-irritant chemicals were maintained, whereas those of models treated with 14 eye irritant substances resulted in the apparent translocation of ezrins from the cell membrane to the cytoplasm or nucleus by destruction of cell membrane. DISCUSSION: Ezrin may be used as a complementary marker to more accurately assess ocular toxicity using 3D reconstructed human cornea-like epithelium models. PMID- 29471019 TI - Hsp90 Co-chaperone p23 contributes to dopaminergic mitochondrial stress via stabilization of PHD2: Implications for Parkinson's disease. AB - The heat shock factor 90 (hsp90) complex has long been associated with neuropathological phenotypes linked to Parkinson's disease (PD) and its inhibition is neuroprotective in disease models. Hsp90 is conventionally believed to act by suppressing induction of hsp70. Here, we report a novel hsp70 independent mechanism by which Hsp90 may also contribute to PD-associated neuropathology. We previously reported that inhibition of the enzyme prolyl hydroxylase domain 2 (PHD2) in conjunction with increases in hypoxia-inducible factor 1 alpha (HIF1alpha) results in protection of vulnerable dopaminergic substantia nigra pars compacta (DAergic SNpc) neurons in in vitro and in vivo models of PD. We discovered an increased interaction between PHD2 and the p23:Hsp90 chaperone complex in response to mitochondrial stress elicited by the mitochondrial neurotoxin 1-methyl-4-phenylpyridine (MPP+) within cultured DAergic cells. Genetic p23 knockdown was found to result in decreases in steady-state PHD2 protein and activity and reduced susceptibility to MPP+ neurotoxicity. Administration of the p23 inhibitor gedunin was also neuroprotective in these cells as well as in human induced pluripotent stem cell (iPSC)-derived neurons. Our data suggests that mitochondrial stress-mediated elevations in PHD2 interaction with the p23-hsp90 complex have detrimental effects on the survival of DAergic neurons, while p23 inhibition is neuroprotective. We propose that neurotoxic effects are tied to enhanced PHD2 stabilization by the hsp90-p23 chaperone complex that is abrogated by p23 inhibition. This demonstrates a novel connection between two independent pathways previously linked to PD, hsp90 and PHD2-HIF1alpha, which could have important implications for here-to-fore unexplored mechanisms underlying PD neuropathology. PMID- 29471022 TI - Temporal lobe epilepsy-induced neurodegeneration and cognitive deficits: Implications for aging. AB - Epilepsy is a neurological condition associated with seizures, neurodegeneration, circuit reorganization, and other structural and functional abnormalities. These elements ultimately lead to behavioural alterations such as anxiety, depression, and importantly cognitive impairment like learning disability and memory impairment. These factors can attribute to acceleration of aging and cognitive impairment in middle-aged people, which is otherwise evident in dementia and Alzheimer's disease among elderly people. In addition to epilepsy per se, several studies have shown that conventional anti-epileptic drugs used to treat epilepsy also contributes to aging and cognitive deficits through their adverse effects. The current review focuses on prevention of accelerated aging and cognitive impairment through an unconventional approach of combining non-pharmacological (enriched environment) and pharmacological therapy, which reduces the factors responsible for accentuated aging and memory impairment in chronic epileptic condition. PMID- 29471021 TI - Does male preference play a role in maintaining female limited polymorphism in a Batesian mimetic butterfly? AB - Female-limited polymorphism occurs in multiple butterfly species with Batesian mimicry. While frequency-dependent selection is often argued as the driving force behind polymorphism in Batesian mimicry systems, male preference and alternative female mating strategies may also influence the maintenance of multiple female forms. Through a series of behavioural assays with the female-limited Batesian mimetic butterfly Papilio polytes, we show that males prefer stationary mimetic females over stationary non-mimetic females, but weigh female activity levels more heavily than female wing pattern when choosing between active mimetic and active non-mimetic females. Male preference for mimetic vs. non-mimetic females is independent of male genotype at the locus responsible for the female wing pattern, the autosomal gene doublesex. However male genotype does influence their response to active females. Male emphasis on female behaviour instead of appearance may reduce sexual selection pressures on female morphology, thereby facilitating frequency-dependent natural selection due to predation risk and toxic model abundance.

PMID- 29471024 TI - In situ antimicrobial behavior of materials with copper-based additives in a hospital environment. AB - Copper and its alloys are effective antimicrobial surface materials in the laboratory and in clinical trials. Copper has been used in the healthcare setting to reduce environmental contamination, and thus prevent healthcare-associated infections, complementing traditional protocols. The addition of copper nanoparticles to polymer/plastic matrices can also produce antimicrobial materials, as confirmed under laboratory conditions. However, there is a lack of studies validating the antimicrobial effects of these nanocomposite materials in clinical trials. To satisfy this issue, plastic waiting room chairs with embedded metal copper nanoparticles, and metal hospital IV pools coated with an organic paint with nanostructured zeolite/copper particles were produced and tested in a hospital environment. These prototypes were sampled once weekly for 10 weeks and the viable microorganisms were analysed and compared with the copper-free materials. In the waiting rooms, chairs with copper reduced by around 73% the total viable microorganisms present, showing activity regardless of the microorganism tested. Although there were only low levels of microorganisms in the IV pools installed in operating rooms because of rigorous hygiene protocols, samples with copper presented lower total viable microorganisms than unfilled materials. Some results did not have statistical significance because of the low load of microorganisms; however, during at least three weeks the IV pools with copper had reduced levels of microorganisms by a statistically significant 50%. These findings show for the first time the feasibility of utilizing the antimicrobial property of copper by adding nanosized fillers to other materials in a hospital environment. PMID- 29471025 TI - Releasing iron from ferritin protein nanocage by reductive method: The role of electron transfer mediator. AB - BACKGROUND: Ferritin detoxifies excess of free Fe(II) and concentrates it in the form of ferrihydrite (Fe2O3.xH2O) mineral. When in need, ferritin iron is released for cellular metabolic activities. However, the low solubility of Fe(III) at neutral pH, its encapsulation by stable protein nanocage and presence of dissolved O2 limits in vitro ferritin iron release. METHODS: Physiological reducing agent, NADH (E1/2 = -330 mV) was inefficient in releasing the ferritin iron (E1/2 = +183 mV), when used alone. Thus, current work investigates the role of low concentration (5-50 MUM) of phenazine based electron transfer (ET) mediators such as FMN, PYO - a redox active virulence factor secreted by Pseudomonas aeruginosa and PMS towards iron mobilization from recombinant frog M ferritin. RESULTS: The presence of dissolved O2, resulting in initial lag phase and low iron release in FMN, had little impact in case of PMS and PYO, reflecting their better ET relay ability that facilitates iron mobilization. The molecular modeling as well as fluorescence studies provided further structural insight towards interaction of redox mediators on ferritin surface for electron relay. CONCLUSIONS: Reductive mobilization of iron from ferritin is dependent on the relative rate of NADH oxidation, dissolved O2 consumption and mineral core reduction, which in turn depends on E1/2 of these mediators and their interaction with ferritin. GENERAL SIGNIFICANCE: The current mechanism of in vitro iron mobilization from ferritin by using redox mediators involves different ET steps, which may help to understand the iron release pathway in vivo and to check microbial growth. PMID- 29471026 TI - Fungal extracellular vesicles: modulating host-pathogen interactions by both the fungus and the host. AB - The secretion of biomolecules by fungal cells occurs via the conventional export of signal peptide-coupled soluble molecules, but it also results from transport within extracellular vesicles (EV). During the last ten years since the description of this non-conventional secretion pathway, varied, interesting biological roles have been associated with EV release by fungi. The various organic molecules carried by these structures are involved in pathogenesis and immune evasion, and may be associated with cell-cell communication. In regards to host-pathogen interactions, EV roles are diverse and organism-specific, although some features seem to be conserved among the pathogenic fungal organisms studied to date. This review aims to highlight our current understanding of the biologically relevant findings regarding EV released by the pathogenic fungal organisms and describes our knowledge of the roles of EV in host-pathogen interactions. PMID- 29471027 TI - Cytotoxic homoisoflavonoids from the bulbs of Bellevalia flexuosa. AB - Four new homoisoflavonoids, 7-O-methyl-8-demethoxy-3'-hydroxy-3,9 dihydropunctatin (4), 6-hydroxy-8-demethoxy-4'-O-methyl-3,9-dihydropunctatin (8), 7,4'-O-dimethyl-8-demethoxy-3,3'-dihydroxy-3,9-dihydropunctatin (13), and 7-O methyl-3-hyroxy-3,9-dihydropunctatin (14) were identified from a chloroform extract of the bulbs of Bellevalia flexuosa, along with 13 known analogues. The structures were determined by analysis of HRMS and NMR data, while ECD spectroscopy enabled the assignment of the absolute configurations of the new compounds 4, 8, 13 and 16. The cytotoxic activities of the isolated compounds (1 17) were evaluated using a panel of human cancer cell lines. Compounds 2 and 7 were the most potent against the MDA-MB-435 (melanoma) cancer cell line with IC50 values of 1.6 and 2.0 MUM, respectively, and were essentially equipotent against the OVCAR3 (ovarian) cancer cell line with IC50 values of 9.5 and 10.8 MUM, respectively. However, compound 7, with an IC50 value of 3.6 MUM, was the most potent against the MDA-MB-231 (breast) cancer cell line. PMID- 29471028 TI - The structural and functional brain networks that support human social networks. AB - Social skills rely on a specific set of cognitive processes, raising the possibility that individual differences in social networks are related to differences in specific brain structural and functional networks. Here, we tested this hypothesis with multimodality neuroimaging. With diffusion MRI (DMRI), we showed that differences in structural integrity of particular white matter (WM) tracts, including cingulum bundle, extreme capsule and arcuate fasciculus were associated with an individual's social network size (SNS). A voxel-based morphology analysis demonstrated correlations between gray matter (GM) volume and SNS in limbic and temporal lobe regions. These structural changes co-occured with functional network differences. As a function of SNS, dorsomedial and dorsolateral prefrontal cortex showed altered resting-state functional connectivity with the default mode network (DMN). Finally, we integrated these three complementary methods, interrogating the relationship between social GM clusters and specific WM and resting-state networks (RSNs). Probabilistic tractography seeded in these GM nodes utilized the SNS-related WM pathways. Further, the spatial and functional overlap between the social GM clusters and the DMN was significantly closer than other control RSNs. These integrative analyses provide convergent evidence of the role of specific circuits in SNS, likely supporting the adaptive behavior necessary for success in extensive social environments. PMID- 29471029 TI - The contribution of left heart disease in COPD patients with pulmonary hypertension. AB - BACKGROUND: Pulmonary hypertension (PH), regardless of its etiology, is associated with an impaired outcome in patients with chronic obstructive pulmonary disease (COPD). The aim of our study was to determine the incidence, cause, and effect of PH as detected by echocardiography in COPD patients. METHODS: Patients with confirmed COPD of any stage were evaluated by echocardiography for the likelihood of PH according to the proposed criteria. Patients with possible/likely to have PH underwent right heart catheterization, upon agreement, to confirm the presence, severity, and cause of PH. RESULTS: Of 91 patients, 39 were in stable condition (group A) and 52 with COPD exacerbation (group B). Group B patients presented with PH and left ventricular diastolic dysfunction more often than group A patients. One of two fulfilled the criteria for possible/likely PH. The incidence of likely/possible PH was significantly higher in group B. Nineteen group B patients with likely/possible PH underwent RHC, and PH was confirmed in 15 cases and in 73.3% was associated with left heart disease. The presence of possible/likely PH was associated with a statistically significant increase in mortality compared to those with unlikely PH. CONCLUSIONS: The use of echocardiographic criteria for the presence of PH is adequate for the screening of COPD patients. Patients with acute exacerbation of COPD and possible/likely PH demonstrate worse mortality compared to patients unlikely to have PH. PMID- 29471030 TI - Neuroprotective effects of fecal microbiota transplantation on MPTP-induced Parkinson's disease mice: Gut microbiota, glial reaction and TLR4/TNF-alpha signaling pathway. AB - Parkinson's disease (PD) patients display alterations in gut microbiota composition. However, mechanism between gut microbial dysbiosis and pathogenesis of PD remains unexplored, and no recognized therapies are available to halt or slow progression of PD. Here we identified that gut microbiota from PD mice induced motor impairment and striatal neurotransmitter decrease on normal mice. Sequencing of 16S rRNA revealed that phylum Firmicutes and order Clostridiales decreased, while phylum Proteobacteria, order Turicibacterales and Enterobacteriales increased in fecal samples of PD mice, along with increased fecal short-chain fatty acids (SCFAs). Remarkably, fecal microbiota transplantation (FMT) reduced gut microbial dysbiosis, decreased fecal SCFAs, alleviated physical impairment, and increased striatal DA and 5-HT content of PD mice. Further, FMT reduced the activation of microglia and astrocytes in the substantia nigra, and reduced expression of TLR4/TNF-alpha signaling pathway components in gut and brain. Our study demonstrates that gut microbial dysbiosis is involved in PD pathogenesis, and FMT can protect PD mice by suppressing neuroinflammation and reducing TLR4/TNF-alpha signaling.

AB - BACKGROUND: Asthma morbidity is high in low-income children living in rural US regions, yet few interventions have been designed to decrease the asthma burden in rural populations. OBJECTIVE: To examine the effect of a school-based asthma education program delivered by telemedicine in children living in an impoverished rural region. METHODS: We conducted a cluster randomized trial with rural children 7 to 14 years old by comparing a school-based telemedicine asthma education intervention with usual care. The intervention provided comprehensive asthma education by telemedicine to participants and provided evidence-based treatment recommendations to primary care providers. RESULTS: Of the 393 enrolled children, median age was 9.6 years, 81% were African American, and 47% lived in households with an annual income less than $14,999. At enrollment, 88% of children reported uncontrolled asthma symptoms. At the end of the intervention, there were no statistically significant differences in reported symptom-free days (primary outcome) for the intervention or usual-care group. Participants in the intervention group reported significantly higher use of peak flow meters to monitor asthma and reported taking their asthma medications as prescribed more frequently compared with the usual-care group. There were no changes in other outcome measures, including quality of life, self-efficacy, asthma knowledge, or lung function, between groups. CONCLUSION: Although there was some evidence of behavior change among intervention participants, these changes were inadequate to overcome the significant morbidity experienced by this highly symptomatic rural impoverished population. Future interventions should be designed with a multifaceted approach that considers caregiver engagement, distance barriers, and inadequate access to asthma providers in rural regions. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT01167855. PMID- 29471033 TI - Inhibition of lymphocyte proliferation: An ability shared by murine mesenchymal stem cells, dermal fibroblasts and chondrocytes. AB - It has been demonstrated that mesenchymal stem cells (MSCs) have potent immunosuppressive capacities. But it is controversial whether differentiated mature stromal cells (SCs) share the immunosuppressive capacities. A previous study examined the ability of SCs from different human tissue sites to inhibit the proliferation of lymphocytes. The results are all positive but the mechanism isn't clear, and few mouse data have been published on this topic. Using an efficient mixed cell culture assay, our in vitro data show that the anti proliferative ability of murine MSCs on lymphocytes is shared by mature murine SCs, i.e. chondrocytes and fibroblasts. Though conflicting results have been published, our results suggest that nitric oxide and IFN-gamma are critical to the immunosuppressive effect. We also demonstrate that murine MSCs cultivated in chondrogenic differentiation medium still possess the anti-proliferative capacities on lymphocytes in vitro. PMID- 29471035 TI - How Safe Is the Safety Net? Comparison of Ivor-Lewis Esophagectomy at a Safety Net Hospital Using the NSQIP Database. AB - BACKGROUND: Recent data suggest that surgical outcomes at hospitals caring for low-income, vulnerable populations are suboptimal compared with outcomes from nonsafety-net hospitals. Therefore, the purpose of our study was to compare outcomes for patients who underwent an Ivor-Lewis esophagectomy at a safety-net hospital with the National Surgical Quality Improvement Program (NSQIP) database. STUDY DESIGN: We retrospectively reviewed the medical records of consecutive patients who underwent an Ivor-Lewis esophagectomy, between September 2013 and January 2017, at a single safety-net hospital. Patient characteristics and outcomes were compared with the 2013 to 2015 NSQIP database. Continuous variables were compared using Student's t-test, and categorical variables were analyzed using chi-square tests. Values of p < 0.05 were considered significant. RESULTS: We identified 78 patients from the safety-net hospital and 1,825 patients in the NSQIP database who underwent an Ivor-Lewis esophagectomy. Baseline characteristics were similar, except the safety-net hospital patients were more likely to have COPD (19.2% vs 8.1%; p = 0.001) and be current smokers (42.3% vs 26.0%; p = 0.001); patients in the NSQIP group had a higher BMI (28 kg/m2 vs 26 kg/m2; p = 0.001). There were no differences between groups for mortality, readmission, discharge destination, or mean operative time. Safety-net hospital patients had significantly fewer complications (16.7% vs 33.3%; p = 0.003), fewer reoperations (6.4% vs 14.5%; p = 0.046), and shorter hospital length of stay (10.3 vs 13.1 days; p = 0.001). CONCLUSIONS: Patients who underwent an Ivor-Lewis esophagectomy at a safety-net hospital had fewer complications and reoperations, and a shorter hospital length of stay compared with a national cohort. These findings illustrate the value of clinical pathways in optimizing the patient outcomes at safety-net hospitals and providing excellent care to their vulnerable patient population. PMID- 29471036 TI - eNOS S-nitrosylation mediated OxLDL-induced endothelial dysfunction via increasing the interaction of eNOS with beta-catenin. AB - Protein S-nitrosylation plays an important role in the progression of cardiovascular diseases. eNOS can be S-nitrosylated in endothelial cells, and this modification reversibly attenuates enzyme activity. Under physiological conditions, eNOS directly interacts with beta-catenin. However, whether and how eNOS S-nitrosylation regulates the beta-catenin signal pathway and participates in endothelial dysfunction remains unknown. Here, we show that OxLDL induces the S-nitrosylation of eNOS, which enhances the interaction between eNOS and beta catenin, transcriptional activity of beta-catenin, cell migration and adhesion molecule expression in endothelial cells. In addition, these effects are partially abolished after eNOS is mutated at Cys94 and Cys99, but not Cys441, in endothelial cells. Furthermore, OxLDL increases iNOS expression. The specific iNOS inhibitor 1400 W decreases eNOS S-nitrosylation and the association of eNOS and beta-catenin, thereby blocking the beta-catenin signal pathway to alleviate OxLDL-induced endothelial dysfunction. Taken together, OxLDL induces eNOS S nitrosylation at Cys94 and Cys99 via an iNOS-dependent manner, which may increase beta-catenin activation and trigger endothelial injury. This study describes a novel mechanism of endothelial dysfunction. PMID- 29471034 TI - The Microbiome and Hematopoietic Cell Transplantation: Past, Present, and Future. PMID- 29471038 TI - Co-delivery nanoparticle to overcome metastasis promoted by insufficient chemotherapy. AB - Heterogeneous distribution of drug inside tumor is ubiquitous, causing regional insufficient chemotherapy, which might be the hotbed for drug resistance, tumor cell repopulation and metastasis. Herein, we verify, for the first time, that heterogeneous drug distribution induced insufficient chemotherapy would accelerate the process of epithelial mesenchymal transition (EMT), consequently resulting in the promotion of tumor metastasis. To eliminate the insufficient chemotherapy promoted metastasis, we conceived a co-delivery strategy by hydroxyethyl starch-polylactide (HES-PLA) nanoparticle, in which DOX and TGF-beta receptor inhibitor, LY2157299 (LY), were administered together. In vitro and in vivo studies demonstrate that this co-delivery strategy can simultaneously suppress primary tumor and distant metastasis. Further study on immunofluorescence images of primary tumor verifies that low dose of DOX exasperates the EMT process, whereas the co-delivery nanoparticle can dramatically inhibit the progression of EMT. We reveal the impact of heterogeneous drug distribution on tumor metastasis and develop an effective co delivery strategy to suppress the metastasis, providing guidance for clinical cancer therapy. PMID- 29471037 TI - Butyrophilin3A proteins and Vgamma9Vdelta2 T cell activation. AB - Despite playing critical roles in the immune response and having significant potential in immunotherapy, gammadelta T cells have garnered little of the limelight. One major reason for this paradox is that their antigen recognition mechanisms are largely unknown, limiting our understanding of their biology and our potential to modulate their activity. One of the best-studied gammadelta subsets is the human Vgamma9Vdelta2T cell population, which predominates in peripheral blood and can combat both microbial infections and cancers. Although it has been known for decades that Vgamma9Vdelta2T cells respond to the presence of small pyrophosphate-based metabolites, collectively named phosphoantigens (pAgs), derived from microbial sources or malignant cells, the molecular basis for this response has been unclear. A major breakthrough in this area came with the identification of the Butyrophilin 3A (BTN3A) proteins, members of the Butyrophilin/Butyrophilin-like protein family, as mediators between pAgs and Vgamma9Vdelta2T cells. In this article, we review the most recent studies regarding pAg activation of human Vgamma9Vdelta2T cells, mainly focusing on the role of BTN3A as the pAg sensing molecule, as well as its potential impact on downstream events of the activation process.

AB - A recombinant proinsulin-transferrin fusion protein (ProINS-Tf) has been previously reported to be a novel long-lasting INS analog, acting specifically on the inhibition of hepatic glucose output. In this study, we investigated the biodistribution, activation and tissue retention of ProINS-Tf to elucidate its liver targeted anti-diabetic mechanism. The biodistribution study revealed that ProINS-Tf exhibited liver specific accumulation after a single intravenous injection, whereas transferrin (Tf) or insulin (INS) showed relatively even distribution among different organs. The conversion of inactive ProINS-Tf into an active immune-reactive INS-Tf form (irINS-Tf) via a Tf receptor (TfR) mediated process only occurred in the liver, but not in other organs. In addition, ProINS Tf demonstrated a prolonged retention in the liver after an intravenous injection, suggesting the enhanced association of the bifunctional active form, irINS-Tf, within liver cells. Taken together, our results indicate that ProINS-Tf is a highly liver-targeted INS prodrug with a combination of 3 specific actions in liver cells: (1) TfR-mediated binding and uptake of the prodrug on the cell surface, (2) liver-specific, TfR-mediated conversion of the prodrug into its active form, and (3) the bifunctional binding of the active fusion protein to both Tf and INS receptors in the liver to achieve prolonged retention and thus enhanced anti-diabetic activities. PMID- 29471041 TI - Mechanically activated ion channels. AB - The ability of cells to sense and respond to their physical environment is fundamental to a broad spectrum of biological processes. Cells express an array of force sensors that can transduce mechanical inputs into biochemical signals, including the mechanically activated ion channels PIEZO1, PIEZO2 and TRPV4. The identification and characterisation of mechanically activated ion channels has proven challenging, as has identifying their mode of activation and regulation in vivo. However, the diverse channelopathies associated with the known channels highlights their physiological importance. PMID- 29471042 TI - Aspirin-induced attenuation of adipogenic differentiation of bone marrow mesenchymal stem cells is accompanied by the disturbed epigenetic modification. AB - Aspirin has positive effects on bone marrow mesenchymal stem cells (BMSCs) osteogenic differentiation. However, researchers did not give much thought to its effect on BMSCs adipogenic differentiation. Here, we analyzed the effect of aspirin on the BMSCs adipogenic differentiation. To detect whether the effect of aspirin on the adipogenic differentiation of BMSCs is associated with the disturbed epigenetic modification, the expression of histone deacetylases (HDACs), activity of HDACs and HAT, global histone H3 acetylation and H3k9 acetylation alterations were investigated. Moreover, to further explore and understand the binding mode between aspirin and HDACs, an attempt was made to identify the interaction between aspirin and the HDACs with the aid of in silico docking study. The results showed that aspirin could induce inhibition of BMSCs adipogenesis. The level of HDAC activity, global histone H3 acetylation, and H3k9 acetylation were all down regulated during adipogenic differentiation, and aspirin can reverse these decreases. Furthermore, the HDAC isoforms have different expression patterns in those progresses. The expression of HDAC9 was increased in a does-dependent manner when aspirin was introduced during BMSCs adipogenic differentiation. Docking study showed that high affinity of HDAC9 to aspirin was existed, suggesting that HDAC9 may has an important role in the process of aspirin-induced suppression of adipogenesis. Further studies are needed to define the intricate mechanisms of the HDAC isoforms, and all of these enable us to understand aspirin and its efficacy of inhibition of adipogenic differentiation and pave the way to aspirin clinical using for the tissue regenerating.

AB - The purpose of public reporting is to provide transparency and accountability so that patients and their families can make informed choices. Our ability to assess and publicly report quality in congenital cardiac surgery is constrained by the available data and statistical techniques. Efforts should be directed toward collecting and evaluating information that provides a broad picture of what makes a high-quality program.

PMID- 29471044 TI - Engineered protein degradation of farnesyl pyrophosphate synthase is an effective regulatory mechanism to increase monoterpene production in Saccharomyces cerevisiae. AB - Monoterpene production in Saccharomyces cerevisae requires the introduction of heterologous monoterpene synthases (MTSs). The endogenous farnesyl pyrosphosphate synthase (FPPS; Erg20p) competes with MTSs for the precursor geranyl pyrophosphate (GPP), which limits the production of monoterpenes. ERG20 is an essential gene that cannot be deleted and transcriptional down-regulation of ERG20 has failed to improve monoterpene production. Here, we investigated an N degron-dependent protein degradation strategy to down-regulate Erg20p activity. Degron tagging decreased GFP protein half-life drastically to 1 h (degron K3K15) or 15 min (degrons KN113 and KN119). Degron tagging of ERG20 was therefore paired with a sterol responsive promoter to ensure sufficient metabolic flux to essential downstream sterols despite the severe destabilisation effect of degron tagging. A dual monoterpene/sesquiterpene (linalool/nerolidol) synthase, AcNES1, was used as a reporter of intracellular GPP and FPP production. Transcription of the synthetic pathway was controlled by either constitutive or diauxie-inducible promoters. A combination of degron K3K15 and the ERG1 promoter increased linalool titre by 27-fold to 11 mg L-1 in the strain with constitutive promoter constructs, and by 17-fold to 18 mg L-1 in the strain with diauxie-inducible promoter constructs. The sesquiterpene nerolidol remained the major product in both strains. The same strategies were applied to construct a limonene-producing strain, which produced 76 mg L-1 in batch cultivation. The FPPS regulation method developed here successfully redirected metabolic flux toward monoterpene production. Examination of growth defects in various strains suggested that the intracellular FPP concentration had a significant effect on growth rate. Further strategies are required to balance intracellular production of FPP and GPP so as to maximise monoterpene production without impacting on cellular growth. PMID- 29471045 TI - PRDM14, a putative histone methyl-transferase, interacts with and decreases the stability and activity of the HOXA1 transcription factor. AB - Understanding how the activity of transcription factors like HOX proteins is regulated remains a widely open question. In a recent screen for proteins interacting with HOXA1, we identified a PRDM protein family member, PRDM14, which is known to be transiently co-expressed with HOXA1 in epiblast cells before their specification towards somatic versus germ cell fate. Here, we confirm PRDM14 is an interactor of HOXA1 and we identify the homeodomain of HOXA1 as well as the PR domain and Zinc fingers of PRDM14 to be required for the interaction. An 11-His repeat of HOXA1 previously highlighted to contribute to HOXA1-mediated protein protein interactions is also involved. At a functional level, we provide evidence that HOXA1 displays an unexpectedly long half-life and demonstrate that PRDM14 can reduce the stability and affect the transcriptional activity of HOXA1. PMID- 29471046 TI - Congenital microcephaly: A diagnostic challenge during Zika epidemics. AB - The multiple, wide and diverse etiologies of congenital microcephaly are complex and multifactorial. Recent advances in genetic testing have improved understanding of novel genetic causes of congenital microcephaly. The recent Zika virus (ZIKV) epidemic in Latin America has highlighted the need for a better understanding of the underlying pathological mechanisms of microcephaly including both infectious and non-infectious causes. The diagnostic approach to microcephaly needs to include potential infectious and genetic etiologies, as well as environmental in-utero exposures such as alcohol, toxins, and medications. Emerging genetic alterations linked to microcephaly include abnormal mitotic microtubule spindle structure and abnormal function of centrosomes. We discuss the diagnostic challenge of congenital microcephaly in the context of understanding the links with ZIKV emergence as a new etiological factor involved in this birth defect.

AB - We used a comprehensive metabolomics approach to study the altered urinary metabolome of two mitochondrial myopathy, encephalopathy lactic acidosis and stroke like episodes (MELAS) cohorts carrying the m.3243A>G mutation. The first cohort were used in an exploratory phase, identifying 36 metabolites that were significantly perturbed by the disease. During the second phase, the 36 selected metabolites were able to separate a validation cohort of MELAS patients completely from their respective control group, suggesting usefulness of these 36 markers as a diagnostic set. Many of the 36 perturbed metabolites could be linked to an altered redox state, fatty acid catabolism and one-carbon metabolism. However, our evidence indicates that, of all the metabolic perturbations caused by MELAS, stalled fatty acid oxidation prevailed as being particularly disturbed. The strength of our study was the utilization of five different analytical platforms to generate the robust metabolomics data reported here. We show that urine may be a useful source for disease-specific metabolomics data, linking, amongst others, altered one-carbon metabolism to MELAS. The results reported here are important in our understanding of MELAS and might lead to better treatment options for the disease.

The purpose of this paper is to present an innovative guided surgery system which originality lies in its guidance device, and to report the author's experience in using this system for dental implant surgery. TECHNICAL PROTOCOL: Two parallel tubes on either side of the drilling axis guide the successive drills and the implant placement. As a result of the lateral guidance, there is no friction of the drills on the surgical guide, which would damage it or contaminate the drilling hole with particles torn out from the guide. No radiological guide is needed during the radiographic examination stage. No successive diameter reduction tubes are requested. This guide can be used for all brands of implants. DISCUSSION: In our experience, 67 implants (31 titanium and 36 zircon implants) were placed in 35 patients with guided surgery system. Multiple clinical cases were treated with this system: 'one-stage' or a 'two stage' surgical protocol, with flap and flapless surgical techniques, and with delayed or immediate loading. Clinical cases treated revealed good implant placement with planning. The widely open design of this guide allows irrigation and practitioner's sight control under conditions comparable to those of operations performed without surgical guide. CONCLUSION: This dental implant guided system appears to be a significant advance in the field of implant surgical guides. PMID- 29471049 TI - Temporomandibular joint arthroplasty for osteoarthrosis: A series of 24 patients that received a uni- or bilateral inter-positional silicone sheet. AB - PURPOSE: To evaluate mid-term results from using a silicone sheet for inter positional arthroplasty in moderate or severe cases of osteoarthrosis of the temporo-mandibular joint (TMJ). To also determine any remaining indications from this method. PATIENTS AND METHODS: This retrospective study included patients that underwent surgery between 2008 and 2016. Pre- and post-operative mouth opening (MO), according to inter-incisal distance (mm) and pain score (PS: 0=no pain to 4=very severe pain) were recorded for 24 patients. Patients were divided according to thickness of the silicone sheet (group A: 1.0 mm, group B: 1.5 mm). RESULTS: The cohort included 22 females (92%). Mean age at surgery was 55 years+/ 13 (26-80). Mean length of follow-up was 26 months+/-24 (6-80). Mean improvement in MO was 8.2 mm (+33%) and of PS was 1.7 (-68%). MO was not improved for two patients and worsened for one. PS score improved for all patients. No statistical difference was found between groups A and B. There was also a tendency for degradation of outcomes over time. CONCLUSION: The poor reputation of prosthetic discoplasty was not as evident in our series, even though anatomical and functional status seemed to deteriorate over time. This is because total-joint prosthetic replacement is often proposed instead. However, for elderly or fragile patients that have severe pain, and regarding cost-benefit aspects, conventional arthroplasty can still be discussed, especially since French national health-care insurance does not yet support TMJ prosthetic replacement for osteoarthrosis. PMID- 29471050 TI - The protein-protein interactions between Amsacta moorei entomopoxvirus (AMEV) protein kinases (PKs) and all viral proteins. AB - Entomopoxviruses are an important group of viruses infecting only insects. They belong to Poxviridae which infect both invertebrates and vertebrates, including humans. Protein kinases are known to have roles at virus morphogenesis, host selectivity, the regulation of cell division and apoptosis in some vertebrate poxviruses. In this study, 2 protein kinases (PKs) (AMV153 and AMV197) of Amsacta moorei entomopoxvirus (AMEV) were investigated for the interactions among 230 viral proteins using yeast two-hybrid system (Y2H). For this purpose, two protein kinases and 230 viral genes were cloned into the bait and prey vectors, respectively. Bait vectors were introduced into Saccharomyces cerevisiae AH109. Expression of the bait genes were confirmed by western blot analysis. Both yeast strains of bait were transformed individually with each prey clone and grown on a selective medium (minimal synthetic defined) to determine the protein-protein interactions between bait and prey proteins. Transformations identified totally 16 interactions among AMEV protein kinases and all viral proteins of which 5 belong to AMV153 and 11 belong to AMV197. One of the five interactions detected for AMV153 protein kinase is self-association. Its other four interactions are with two virus entry complex proteins (AMV035 and AMV083), a membrane protein (AMV165) and a subunit of RNA polymerase (AMV230). The other protein kinase, AMV197, interacted with two virus entry complex proteins (AMV035 and AMV083) as AMV153, a caspase-2 enzyme (AMV063), a Holliday junction resolvase (AMV162), a membrane protein (AMV165), a subunit of RNA polymerase (AMV230) and five other hypothetical proteins (AMV026, AMV040, AMV062, AMV069, AMV120) encoded by AMEV genome. Glutathione S-transferase (GST) pull-down assay was used to confirm all interactions described by Y2H analysis. In addition, the theoretical structures of the two of 16 interactions were interpreted by docking analysis. Consistent with Y2H and pull down assays, docking analysis also showed the interactions of AMV063 with AMV153 and AMV197. Detected interactions of the AMEV viral proteins with viral protein kinases could lead to the understanding of the regulation of the viral activities of interacted viral proteins. PMID- 29471051 TI - An analysis of two open reading frames (ORF3 and ORF4) of rat hepatitis E virus genome using its infectious cDNA clones with mutations in ORF3 or ORF4. AB - Rat hepatitis E virus (ratHEV) genome has four open reading frames (ORFs: ORF1, ORF2, ORF3 and ORF4). The functions of ORF3 and ORF4 are unknown. An infectious cDNA clone (pUC-ratELOMB-131L_wt, wt) and its derivatives including ORF3 defective (DeltaORF3) and ORF4-defective (DeltaORF4) mutants, were constructed and their full-length RNA transcripts transfected into PLC/PRF/5 cells. DeltaORF3 replicated as efficiently as wt in cells. However, <=1/1000 of the number of progenies were detectable in the culture supernatant of DeltaORF3-infected cells compared with wt-infected cells. ORF4 protein was not detectable in ratHEV infected cells or in the liver tissues of ratHEV-infected rats. No marked differences were noted between wt and DeltaORF4 regarding the viral replication and protein expression. ORF3 mutants with proline-to-leucine mutations at amino acids (aa) 93, 96 and/or 98 in ORF3 were constructed and transfected into PLC/PRF/5 cells. Wt and an ORF3 mutant with leucine at aa 98 (ORF3-L98) replicated efficiently (density 1.15-1.16 g/cm3), while ORF3-L93 + L96 exhibited a decreased viral release and banded at 1.26-1.27 g/cm3, similar to DeltaORF3. In conclusion, the ORF3 protein, especially its proline residues at aa 93 and 96, is essential for the release of membrane-associated ratHEV particles, and ORF4 is unnecessary for the replication of ratHEV. PMID- 29471052 TI - Revisiting rabies virus neutralizing antibodies through infecting BALB/c mice with live rabies virus. AB - This study investigates the production of rabies virus (RABV) neutralizing antibody after virus infection through a mouse model. The BALB/c mice from different age groups (three, five, seven week old) were intramuscularly inoculated with live rabies virus (TX coyote 323R). Without pre-exposure or post exposure prophylaxis (PEP), we found there is a decreased fatality with increased age of animals, the mortalities are 60%, 50%, and 30%, respectively. Interestingly, through assay of rapid fluorescent focus inhibition test (RFFIT), direct fluorescent antibody (DFA) and quantitative Polymerase Chain Reaction (qPCR), the results showed that all the animals that succumbed to rabies challenge, except one, developed circulating neutralizing antibodies, and all the healthy animals, except two, did not generate virus neutralizing antibodies (VNA). Our animal study suggests that the induction of VNA was an indicator of infection progression in the central nervous system (CNS) and speculate that RABV neutralizing antibodies did not cross the blood-brain barrier of the CNS for those diseased animals. We hypothesize that early release of viral antigens from damaged nerve tissue might potentially be a benefit for survivors, and we also discuss several other aspects of the interaction of RABV and its neutralizing antibodies. PMID- 29471055 TI - Brain insulin signalling, glucose metabolism and females' reproductive aging: A dangerous triad in Alzheimer's disease. AB - Alzheimer's disease (AD) constitutes a major socioeconomic challenge due to its disabling features and the rise in prevalence (especially among (peri)menopausal women and type 2 diabetes patients). The precise etiopathogenesis of AD remains poorly understood. Importantly, its neurodegenerative perspective has been challenged towards a more "systemic" view. Amyloid-beta (Abeta) and hyperphosphorylated Tau protein (P-Tau) (the main AD neuropathological features) affect and are affected by peripheral and brain insulin signalling dysfunction, leading to glucose dysmetabolism, synaptic loss and AD-related cognitive deficits. This may be anticipated and exacerbated by the progressive loss of estrogen (and interactions, e.g., with insulin) during females' aging, increasing their risk for AD, especially during menopause. Under this perspective, we aimed to discuss the recent findings (and controversies) behind the peripheral view of AD, and the role for insulin deficits and brain glucose dysmetabolism in such diseased brain. We also focused on the metabolic shift and the putative effects of gender (especially during midlife/perimenopause) herein. We finally discussed AD as the potential "type 3 diabetes", and the therapeutic potential of restoring brain insulin levels or glucose energy metabolism via administration of intranasal insulin and use of ketogenic diets. In sum, AD appears to lie on an intricate crosstalk between age-related metabolic, hormonal and specific genetic changes that challenge its traditional view. Hence, clarification of AD risk factors (besides aging and gender) and pathophysiological mechanisms will allow to establish accurate preventive strategies, biomarkers and more efficient drugs all urgent medical needs in our increasingly aged societies.

PMID- 29471054 TI - Developmental changes of GABA immunoreactivity in cortico-thalamic networks of an absence seizure model. AB - Absence seizures (ASs) are associated with abnormalities in gamma-aminobutyric acid (GABA) neurotransmission in the thalamus and the cortex. In the present study, we used light microscopy GABA immunocytochemistry to quantify the GABA immunoreactive (GABA-IR) neurons and neuropil in the thalamic ventral basal (VB) nucleus, the nucleus reticularis thalami (NRT), the dorsal lateral geniculate (dLGN), the primary motor cortex (M1) and perioral region of the somatosensory cortex (S1po) of genetic absence epilepsy rats from Strasbourg (GAERS). We used both the relative non-epileptic control (NEC) and normal Wistar rats as control strains, and investigated GABA immunostaining at postnatal day 15 (P15), P25, and P90. The main findings were i) an increase in GABA-IR neuropil in the VB at P25 and P90 in GAERS but not in NEC and Wistar rats; ii) an increase in NRT GABA-IR neurons in GAERS and NEC, but not Wistar, rats at both P25 and P90; and iii) an increase in GABA-IR neuron density in S1po of GAERS at P25 and P90 and in Wistar at P90. These results indicate that the increased GABAergic innervation in the VB at P25 most likely contributes to the enhanced tonic inhibition observed in GAERS prior to AS onset, whereas the lack of any anatomo-morphological GABAergic differences in GAERS S1po suggests that functional more than structural abnormalities underlie the origin of cortical paroxysms in S1po of this AS model. This article is part of the "Special Issue Dedicated to Norman G. Bowery". PMID- 29471056 TI - Number of raised steps: A tool to assess brief and intense effort involving anaerobic metabolism. AB - BACKGROUND: Although the initial anaerobic component of exercise adaptation is unavoidable, no specific functional test is available for use in routine non sporting practice to evaluate it. OBJECTIVE: To assess the bioenergetic and biomechanical properties of the Short and Fast Step Test (SFST), which consists of walking up and down a step as many times as possible in 1minute and to analyse its ability to explore the initial anaerobic component of effort in comparison to a reference self-paced step test. METHODS: Overall, 31 healthy subjects (19 women; mean [SD] age, 32.4 [10.2] years) completed a test-retest of a self-paced step test and the SFST, with pre- and post-test measurement of blood lactate concentration and continuous recording of VO2 and modelling of excess post exercise oxygen consumption (EPOC), near-infrared spectroscopy (NIRS) of the quadriceps and mechanical power (estimated by the number of steps climbed and 3-D motion analysis). RESULTS: Both step tests were well tolerated. The reliability of the bioenergetics parameters, number of raised steps, mechanical power and NIRS tissue saturation index was good. Indirect mechanical power (estimated from number of steps) was correlated with direct power (computed from the centre of mass). Lactate accumulation was significantly increased during exercise with only the SFST (mean [SD] increase, 3.86 [3.26]mmolL-1 from resting values, P<0.05). EPOC was higher with the SFST than the self-paced step test (P<0.05). Only the SFST showed significant correlations between number of steps climbed and EPOC (r=0.84; P<0.001) and decreased tissue saturation index (NIRS) and EPOC area (r= 0.39; P<0.05). CONCLUSIONS: SFST is feasible, well tolerated, reliable and responsive to explore a brief exercise involving anaerobic metabolism at submaximal intensity. The number of steps taken in 1minute seems a suitable parameter for practical application. PMID- 29471057 TI - Pediatric brain tumors: Update of proteome-based studies. AB - Pediatric brain tumors (PBTs) are the most common solid malignancies in childhood and continue to pose a serious burden to modern societies. Existing treatments impose debilitating effects on the developing child, highlighting the need for molecularly targeted treatments with reduced toxicity, as well as the necessity of markers that reliably assess efficacy of, and tumor response to targeted therapies of PBTs. On this regard advances in technologies of protein identification and quantification, the large-scale, high-throughput investigation of the proteome, as well the newly-emerging field of "proteogenomics" aim to further our knowledge towards understanding the molecular pathophysiology of PBTs. This mini review article presents all updates on knowledge produced and published during the last years on PBT research derived from "omics" technologies, mainly involving protein research and proteomics. PMID- 29471053 TI - Morphological and functional evidence of increased excitatory signaling in the prelimbic cortex during ethanol withdrawal. AB - Excessive alcohol consumption in humans induces deficits in decision making and emotional processing, which indicates a dysfunction of the prefrontal cortex (PFC). The present study aimed to determine the impact of chronic intermittent ethanol (CIE) inhalation on mouse medial PFC pyramidal neurons. Data were collected 6-8 days into withdrawal from 7 weeks of CIE exposure, a time point when mice exhibit behavioral symptoms of withdrawal. We found that spine maturity in prelimbic (PL) layer 2/3 neurons was increased, while dendritic spines in PL layer 5 neurons or infralimbic (IL) neurons were not affected. Corroborating these morphological observations, CIE enhanced glutamatergic transmission in PL layer 2/3 pyramidal neurons, but not IL layer 2/3 neurons. Contrary to our predictions, these cellular alterations were associated with improved, rather than impaired, performance in reversal learning and strategy switching tasks in the Barnes maze at an earlier stage of chronic ethanol exposure (5-7 days withdrawal from 3 to 4 weeks of CIE), which could result from the anxiety-like behavior associated with ethanol withdrawal. Altogether, this study adds to a growing body of literature indicating that glutamatergic activity in the PFC is upregulated following chronic ethanol exposure, and identifies PL layer 2/3 pyramidal neurons as a sensitive target of synaptic remodeling. It also indicates that the Barnes maze is not suitable to detect deficits in cognitive flexibility in CIE-withdrawn mice. PMID- 29471058 TI - iTRAQ-based quantitative proteomic analysis reveals pathways associated with re establishing desiccation tolerance in germinating seeds of Caragana korshinskii Kom. AB - : Mature seeds of Caragana korshinskii Kom. lose desiccation tolerance (DT) during germination. However, DT can be re-induced by polyethylene glycol (PEG) or abscisic acid (ABA), and this provides a novel system to analyse the mechanism of DT. Although the global gene expression during the re-establishment of DT treated by PEG or ABA has been characterized, the changes in protein species abundance are still unknown. Here, we used an iTRAQ-based quantitative proteomics approach to perform a comparative analysis of protein abundances in germinated seeds of PEG-treated, ABA-treated and untreated radicles in response to the re establishment of DT. A total of 3009 proteins were quantified; compared with the untreated samples, 274 and 261 differentially abundant protein species were found in PEG- and ABA-treated samples, respectively. The observed protein abundance patterns showed a clear overlap in seeds with ABA-and PEG-induced re establishment of DT. During the re-establishment of DT, the expression of auxin repressed protein and metallothionien-like protein was induced, and the content of proline increased significantly; however, proteins related to cell proliferation were found to be expressed at lower levels, and the glycolytic pathway was partially inhibited. These results provide promising insights into the molecular mechanisms underlying the re-establishment of DT in germinated seeds. BIOLOGICAL SIGNIFICANCE: The major challenge for seed storage is the complexity of the tolerance to desiccation. Re-establishment of desiccation tolerance (DT) in germinating seed as a model was used for DT researching. Although several researches have been focusing on the transcriptome of DT re establishment, little proteomic information remained to be available. In the present study, the iTRAQ-based quantitative proteomic analysis was employed to identify the differentially accumulated protein species from radicles of germinating C. korshinskii seedling after ABA-, PEG- treatment or not. The data obtained not only provides basic information about proteome, but also characterize the quantitative changes that occur in the abundance of proteins species during DT re-establishment. These results are helpful understanding the mechanism of DT re-establishment induced by PEG or ABA. PMID- 29471059 TI - Endogenous molecules released by haemocytes receiving Sargassum oligocystum extract lead to downstream activation and synergize innate immunity in white shrimp Litopenaeus vannamei. AB - White shrimp Litopenaeus vannamei haemocytes receiving immunostimulating Sargassum oligocystum extract (SE) caused necrosis in haemocyte cells, which released endogenous EM-SE molecules. This study examined the immune response of white shrimp L. vannamei receiving SE and EM-SE in vitro and in vivo. Shrimp haemocytes receiving SE exhibited degranulation, changes in cell size and cell viability, necrosis and a release of EM-SE. Shrimp haemocytes receiving SE, EM SE, and the SE + EM-SE mixture (SE + EM-SE) increased their phenoloxidase (PO) activity which was significantly higher in shrimp haemocytes receiving the SE + EM-SE mixture. Furthermore, shrimp haemocytes receiving EM-SE showed degranulation and changes in cell size and cell viability. Shrimp receiving SE, EM-SE, and SE + EM-SE all increased their immune parameters, phagocytic activity, clearance efficiency and resistance to Vibrio alginolyticus, being significantly higher in shrimp receiving SE + EM-SE. Meanwhile, the recombinant lipopolysaccharide- and beta-1,3-glucan binding protein of L. vannamei (rLvLGBP) was bound to SE, EM-SE, and SE + EM-SE. We conclude that in shrimp haemocytes receiving a non-self molecule, SE in dying cells released EM-SE which led to downstream activation and synergization of the immune response. This study demonstrated that the innate immunity of shrimp was elicited and enhanced by a mixture of endogenous molecules and exogenous substances (or immunostimulants). PMID- 29471060 TI - Identification of three class A scavenger receptors from rainbow trout (Oncorhynchus mykiss): SCARA3, SCARA4, and SCARA5. AB - Class A scavenger receptors (SR-As) are a family of five surface receptors whose functions in mammals are associated with innate immunity; however, their role in fish immunity requires further elucidation. The present study identifies, performs sequence analysis, and constitutive transcript expression analysis for three SR-A family members, SCARA3, SCARA4 and SCARA5, from rainbow trout. This work will provide a basis for future studies on SR-A function and their role in innate immunity in this economically important fish. PMID- 29471061 TI - Effects of dietary inulin and mannan oligosaccharide on immune related genes expression and disease resistance of Pacific white shrimp, Litopenaeus vannamei. AB - The effects of inulin and mannan oligosaccharide (MOS) at different doses (2.5, 4 and 10 mg/g) in singular or combined diet on growth rate, immune related genes expression, and resistance to white spot syndrome virus (WSSV) and Vibrio alginolyticus in Pacific white shrimp (Litopenaeus vannamei) were investigated. At the end of 28-day singular feeding experiment, the highest values of specific growth rate (SGR) and the expression of toll-like receptor1, 2 and 3 (TLR1, 2, 3), signal transducer and activator of transcription (STAT), crustin, anti lipopolysaccharide factor (ALF) as well as prophenoloxidase (proPO) were observed in shrimp individually fed with 5 mg/g dietary inulin or MOS, respectively. Compared with individual treatments, diet containing combined prebiotics (5 mg/g inulin and MOS) significantly improved the expression of TLRs, STAT, proPO, crustin and ALF in L. vannamei after four-week feeding. Additionally, Pacific white shrimp fed with combined dietary prebiotics showed significantly higher expression of immune related genes and lower cumulative mortality in WSSV and Vibrio alginolyticus challenges, compared to the singular feeding groups and control. These results in the present study demonstrated that the combined supplementation of inulin (5 mg/g) and MOS (5 mg/g) remarkably enhanced innate immune response and pathogen resistance of shrimp, and should be considered as a promising immunostimulatory additive for the culture of Pacific white shrimp. PMID- 29471063 TI - Intermolecular interactions determined by NOE build-up in macromolecules from hyperpolarized small molecules. AB - The nuclear Overhauser effect (NOE) is a primary means to characterize intermolecular interactions using modern NMR spectroscopy. Multiple experiments measured using different mixing time can be used for quantifying NOE buildup and measuring cross-relaxation rates. However, this approach using conventional multi dimensional NMR is time consuming. Hyperpolarization by dissolution dynamic nuclear polarization (D-DNP) can generate deviations from equilibrium spin polarization by orders of magnitude, thereby enhancing signals and allowing to characterize NOE build up in real-time. Since most small molecules can be hyperpolarized using D-DNP, this method is applicable to the study of intermolecular interactions between small molecules and macromolecules. This application is demonstrated using a model system for host-guest interactions including the third generation polyamidoamine dendrimer (G3 PAMAM) and the pharmaceutical phenylbutazone (PBZ). After mixing 1H hyperpolarized PBZ with PAMAM, the NOE build up is directly observed at different sites of the dendrimer in series of one-dimensional NMR spectra. Cross-relaxation rates specific to individual source and target spins are determined from the build up curves. Further, the polarization enhancement is shown to be sufficiently large to allow identification of cross-peaks not observed in a conventional 2D-NOESY spectrum. The improved signal-to-noise ratio provided by hyperpolarization allows for characterizing the intermolecular interaction in an almost instantaneous measurement, opening an application to macromolecular and biomacromolecular NMR. PMID- 29471062 TI - Constitutive stimulatory G protein activity in limb mesenchyme impairs bone growth. AB - GNAS mutations leading to constitutively active stimulatory G protein alpha subunit (Gsalpha) cause different tumors, fibrous dysplasia of bone, and McCune Albright syndrome, which are typically not associated with short stature. Enhanced signaling of the parathyroid hormone/parathyroid hormone-related peptide receptor, which couples to multiple G proteins including Gsalpha, leads to short bones with delayed endochondral ossification. It has remained unknown whether constitutive Gsalpha activity also impairs bone growth. Here we generated mice expressing a constitutively active Gsalpha mutant (Gsalpha-R201H) conditionally upon Cre recombinase (cGsalphaR201H mice). Gsalpha-R201H was expressed in cultured bone marrow stromal cells from cGsalphaR201H mice upon adenoviral-Cre transduction. When crossed with mice in which Cre is expressed in a tamoxifen regulatable fashion (CAGGCre-ERTM), tamoxifen injection resulted in mosaic expression of the transgene in double mutant offspring. We then crossed the cGsalphaR201H mice with Prx1-Cre mice, in which Cre is expressed in early limb bud mesenchyme. The double mutant offspring displayed short limbs at birth, with narrow hypertrophic chondrocyte zones in growth plates and delayed formation of secondary ossification center. Consistent with enhanced Gsalpha signaling, bone marrow stromal cells from these mice demonstrated increased levels of c-fos mRNA. Our findings indicate that constitutive Gsalpha activity during limb development disrupts endochondral ossification and bone growth. Given that Gsalpha haploinsufficiency also leads to short bones, as in patients with Albright's hereditary osteodystrophy, these results suggest that a tight control of Gsalpha activity is essential for normal growth plate physiology. PMID- 29471064 TI - TMS SMART - Scalp mapping of annoyance ratings and twitches caused by Transcranial Magnetic Stimulation. AB - BACKGROUND: The magnetic pulse generated during transcranial magnetic stimulation (TMS) also stimulates cutaneous nerves and muscle fibres, with the most commonly reported side effect being muscle twitches and sometimes painful sensations. These sensations affect behaviour during experimental tasks, presenting a potential confound for 'online' TMS studies. NEW METHOD: Our objective was to systematically map the degree of disturbance (ratings of annoyance, pain, and muscle twitches) caused by TMS at 43 locations across the scalp. Ten participants provided ratings whilst completing a choice reaction time task, and ten different participants provided ratings whilst completing a 'flanker' reaction time task. RESULTS: TMS over frontal and inferior regions resulted in the highest ratings of annoyance, pain, and muscle twitches caused by TMS. We predicted the difference in reaction times (RT) under TMS by scalp location and subjective ratings. Frontal and inferior scalp locations showed the greatest cost to RTs under TMS (i.e., slowing), with midline sites showing no or minimal slowing. Increases in subjective ratings of disturbance predicted longer RTs under TMS. Critically, ratings were a better predictor of the cost of TMS than scalp location or scalp to-cortex distance. The more difficult 'flanker' task showed a greater effect of subjective disturbance. COMPARISON WITH EXISTING METHODS: We provide the data as an online resource (www.tms-smart.info) so that researchers can select control sites that account for the level of general interference in task performance caused by online single-pulse TMS. CONCLUSIONS: The peripheral sensations and discomfort caused by TMS pulses significantly and systematically influence RTs during single-pulse, online TMS experiments. PMID- 29471065 TI - Clustering fMRI data with a robust unsupervised learning algorithm for neuroscience data mining. AB - BACKGROUND: Clustering approaches used in functional magnetic resonance imaging (fMRI) research use brain activity to divide the brain into various parcels with some degree of homogeneous characteristics, but choosing the appropriate clustering algorithms remains a problem. NEW METHOD: A novel application of the robust unsupervised learning approach is proposed in the current study. Robust growing neural gas (RGNG) algorithm was fed into fMRI data and compared with growing neural gas (GNG) algorithm, which has not been used for this purpose or any other medical application. Learning algorithms proposed in the current study are fed with real and free auditory fMRI datasets. RESULTS: The fMRI result obtained by running RGNG was within the expected outcome and is similar to those found with the hypothesis method in detecting active areas within the expected auditory cortices. COMPARISON WITH EXISTING METHOD(S): The fMRI application of the presented RGNG approach is clearly superior to other approaches in terms of its insensitivity to different initializations and the presence of outliers, as well as its ability to determine the actual number of clusters successfully, as indicated by its performance measured by minimum description length (MDL) and receiver operating characteristic (ROC) analysis. CONCLUSIONS: The RGNG can detect the active zones in the brain, analyze brain function, and determine the optimal number of underlying clusters in fMRI datasets. This algorithm can define the positions of the center of an output cluster corresponding to the minimal MDL value. PMID- 29471066 TI - A pharmacokinetic study on lapatinib in type 2 diabetic rats. AB - BACKGROUND: Diabetes mellitus (DM) is a complex metabolic disorder which affects the function of numerous tissues and alters the pharmacokinetic parameters of many drugs. As many oncological patients are diabetics, it is important to determine the influence of this chronic disease on the pharmacokinetics (PK) of anticancer drugs. Lapatinib is a tyrosine kinase inhibitor (TKI), approved for the treatment of human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer. The aim of the study was to compare the PK of lapatinib in normal and type 2 diabetes mellitus (T2DM) model rats. Additionally, the effect of lapatinib on blood glucose concentrations was examined. METHODS: The PK of lapatinib was studied in healthy rats (n=6, the healthy group) and T2DM model rats (n=6, the diabetic group). The rats received lapatinib orally as a single dose of 50mg. Plasma concentrations of lapatinib were measured with high performance liquid chromatography method coupled with a tandem mass spectrometry. RESULTS: The plasma concentrations of lapatinib were increased in the T2DM model rats. There were statistically significant differences between the groups in Cmax (p=0.0104) and AUC0-t (p=0.0265). The reduction of glycaemia in the range of 1.2 41.5% and in the range of 4.1-36.8% was observed in the diabetic and healthy animals, respectively. CONCLUSIONS: Higher concentrations of lapatinib in the diabetic rats may suggest the need for application of lower doses of this TKI in patients with DM. PMID- 29471067 TI - The smell of renal protection against chronic kidney disease: Hydrogen sulfide offers a potential stinky remedy. AB - Chronic kidney disease (CKD) is a common global health challenge characterized by irreversible pathological processes that reduce kidney function and culminates in development of end-stage renal disease. It is associated with increased morbidity and mortality in addition to increased caregiver burden and higher financial cost. A central player in CKD pathogenesis and progression is renal hypoxia. Renal hypoxia stimulates induction of oxidative and endoplasmic reticulum stress, inflammation and tubulointerstitial fibrosis, which in turn, promote cellular susceptibility and further aggravate hypoxia, thus forming a pathological vicious cycle in CKD progression. Although the importance of CKD is widely appreciated, including improvements in the quality of existing therapies such as dialysis and transplantation, new therapeutic options are limited, as there is still increased morbidity, mortality and poor quality of life among CKD patients. Growing evidence indicates that hydrogen sulfide (H2S), a small gaseous signaling molecule with an obnoxious smell, accumulates in the renal medulla under hypoxic conditions, and functions as an oxygen sensor that restores oxygen balance and increases medullary flow. Moreover, plasma H2S level has been recently reported to be markedly reduced in CKD patients and animal models. Also, H2S has been established to possess potent antioxidant, anti-inflammatory, and anti-fibrotic properties in several experimental models of kidney diseases, suggesting that its supplementation could protect against CKD and retard its progression. The purpose of this review is to discuss current clinical and experimental developments regarding CKD, its pathophysiology, and potential cellular and molecular mechanisms of protection by H2S in experimental models of CKD. PMID- 29471068 TI - Weight loss decreases self-reported appetite and alters food preferences in overweight and obese adults: Observational data from the DiOGenes study. AB - People with obesity often struggle to maintain their weight loss after a weight loss period. Furthermore, the effect of weight loss on appetite and food preferences remains unclear. Hence this study investigated the effect of weight loss on subjective appetite and food preferences in healthy, overweight and obese volunteers. A subgroup of adult participants (n = 123) from the Diet Obesity and Genes (DiOGenes) study (subgroup A) was recruited from across six European countries. Participants lost >=8% of initial body weight during an 8-week low calorie diet (LCD). Subjective appetite and food preferences were measured before and after the LCD, in response to a standardized meal test, using visual analogue rating scales (VAS) and the Leeds Food Choice Questionnaire (FCQ). After the LCD, participants reported increased fullness (p < 0.05), decreased desire to eat (p < 0.05) and decreased prospective consumption (p < 0.05) after consuming the test meal. An interaction effect (visit x time) was found for hunger ratings (p < 0.05). Area under the curve (AUC) for hunger, desire to eat and prospective consumption was decreased by 18.1%, 20.2% and 21.1% respectively whereas AUC for fullness increased by 13.9%. Preference for low-energy products measured by the Food Preference Checklist (FPC) decreased by 1.9% before the test meal and by 13.5% after the test meal (p < 0.05). High-carbohydrate and high-fat preference decreased by 11.4% and 16.2% before the test meal and by 17.4% and 22.7% after the meal (p < 0.05). No other effects were observed. These results suggest that LCD induced weight loss decreases the appetite perceptions of overweight volunteers whilst decreasing their preference for high-fat-, high-carbohydrate-, and low-energy products.

AB - We review the research on the association between personality and dietary restraint as measured by commonly-used self-report assessment instruments (Restraint Scale, TFEQ, DEBQ, and EDE-Q). In order to expand our understanding of the potentially different types of dieters, we examine the different personality profiles that emerge from existing studies of restraint and personality, including associations between restraint and body dissatisfaction and body focus, self-esteem, neuroticism, sensation seeking, impulsivity, perfectionism and narcissism. This research provides some preliminary evidence that different measures of restraint are associated not only with different eating behaviours, but that they capture different personality profiles. PMID- 29471069 TI - What's technology cooking up? A systematic review of the use of technology in adolescent food literacy programs. AB - Over one-third of adolescents are overweight or obese. Food literacy (FL), the ability to plan and manage, select, prepare, and eat healthy foods, is a contemporary concept that provides a mechanism to understand the relationship between food-related knowledge and skills and dietary intake. Innovative interventions which focus on the core concepts of FL and include generationally appropriate technology have the potential to provide positive impact on the dietary habits of adolescents. This systematic review followed PRISMA guidelines and employed the Downs and Black criteria for rating studies. Titles and abstracts of 545 articles were collected and reviewed from 13 electronic databases. Studies were selected if they were peer-reviewed, included adolescents 12-19 years-old, incorporated concepts related to FL, and employed technology as part of the intervention. Eight studies, six randomized controlled trials (RCT) and two interventions without controls were included. Seven of the interventions used Internet or web-based platforms to access program components and all RCTs incorporated game elements. Studies included between two and four constructs of FL. All reported positive changes in food intake with five reporting significant positive pre- and post-intervention changes. Few technology-driven FL-related studies exist within the literature. Although all studies reported improvements in dietary intake, due to variation in program design, delivery, and evaluation it is difficult to tease out the effect of the technology component. Continued research is needed to: 1) determine the degree to which FL should be included in interventions to effect a positive change on dietary intake; 2) develop adolescent-specific FL measures to more appropriately evaluate changes in knowledge, food-related skills, and dietary intake; and 3) design technology driven interventions so that technology components can be analyzed separately from other program elements. PMID- 29471071 TI - Intragastric preloads of l-tryptophan reduce ingestive behavior via oxytocinergic neural mechanisms in male mice. AB - Human and laboratory animal studies suggest that dietary supplementation of a free essential amino acid, l-tryptophan (TRP), reduces food intake. It is unclear whether an acute gastric preload of TRP decreases consumption and whether central mechanisms underlie TRP-driven hypophagia. We examined the effect of TRP administered via intragastric gavage on energy- and palatability-induced feeding in mice. We sought to identify central mechanisms through which TRP suppresses appetite. Effects of TRP on consumption of energy-dense and energy-dilute tastants were established in mice stimulated to eat by energy deprivation or palatability. A conditioned taste aversion (CTA) paradigm was used to assess whether hypophagia is unrelated to sickness. c-Fos immunohistochemistry was employed to detect TRP-induced activation of feeding-related brain sites and of oxytocin (OT) neurons, a crucial component of satiety circuits. Also, expression of OT mRNA was assessed with real-time PCR. The functional importance of OT in mediating TRP-driven hypophagia was substantiated by showing the ability of OT receptor blockade to abolish TRP-induced decrease in feeding. TRP reduced intake of energy-dense standard chow in deprived animals and energy-dense palatable chow in sated mice. Anorexigenic doses of TRP did not cause a CTA. TRP failed to affect intake of palatable yet calorie-dilute or noncaloric solutions (10% sucrose, 4.1% Intralipid or 0.1% saccharin) even for TRP doses that decreased water intake in thirsty mice. Fos analysis revealed that TRP increases activation of several key feeding-related brain areas, especially in the brain stem and hypothalamus. TRP activated hypothalamic OT neurons and increased OT mRNA levels, whereas pretreatment with an OT antagonist abolished TRP-driven hypophagia. We conclude that intragastric TRP decreases food and water intake, and TRP-induced hypophagia is partially mediated via central circuits that encompass OT. PMID- 29471072 TI - Neuroreflex control of cardiovascular function is impaired after acute poisoning with chlorpyrifos, an organophosphorus insecticide: Possible short and long term clinical implications. AB - Although it is well-established that severe poisoning by organophosphorus (OP) compounds strongly affects the cardiorespiratory system, the effects of sub lethal exposure to these compounds on the neural control of cardiovascular function are poorly explored. The aim of this study was to evaluate the effects of acute sub-lethal exposure to chlorpyrifos (CPF), a commonly used OP insecticide, on three basic reflex mechanisms involved in blood pressure regulation, the peripheral chemoreflex, the baroreflex and the Bezold-Jarisch reflex. Adult male Wistar rats were injected intraperitoneally with a single dose of CPF (30 mg/kg) or saline (0.9%). 24 h after injections, cardiovascular reflexes were tested in awake rats. Potassium cyanide (KCN) and phenylbiguanide (PBG) were injected intravenously to activate the chemoreflex and the Bezold Jarisch reflex, respectively. The baroreflex was activated by phenylephrine and sodium nitroprusside infusions. Blood samples were taken for measurements of butyrylcholinesterase (BChE) activity while acetylcholinesterase (AChE) activity was measured in brainstem samples. Animals treated with CPF presented signs of intoxication such as ataxia, tremor, lacrimation, salivation, tetany, urination and defecation. The hypertensive and the bradycardic responses of the chemoreflex as well as the hypotensive and bradycardic responses of the Bezold-Jarisch reflex were attenuated in CPF treated animals (P < 0.05). Concerning the baroreflex responses, CPF treatment reduced the bradycardia plateau, the range and the gain of the reflex (P < 0.05). Plasma BChE and brainstem AChE were both reduced significantly after CPF treatment (P < 0.05). Our results showed that acute sub lethal exposure to CPF impairs the cardiovascular responses of homeostatic and defensive cardiovascular reflexes. These effects are associated with a marked inhibition of plasma BChE and brainstem AChE.

AB - Polycyclic aromatic hydrocarbons such as benzo[a]pyrene (BaP) can induce cytochrome P450 1A1 (CYP1A1) via a p53-dependent mechanism. The effect of different p53-activating chemotherapeutic drugs on CYP1A1 expression, and the resultant effect on BaP metabolism, was investigated in a panel of isogenic human colorectal HCT116 cells with differing TP53 status. Cells that were TP53(+/+), TP53(+/-) or TP53(-/-) were treated for up to 48 h with 60 MUM cisplatin, 50 MUM etoposide or 5 MUM ellipticine, each of which caused high p53 induction at moderate cytotoxicity (60-80% cell viability). We found that etoposide and ellipticine induced CYP1A1 in TP53(+/+) cells but not in TP53(-/-) cells, demonstrating that the mechanism of CYP1A1 induction is p53-dependent; cisplatin had no such effect. Co-incubation experiments with the drugs and 2.5 MUM BaP showed that: (i) etoposide increased CYP1A1 expression in TP53(+/+) cells, and to a lesser extent in TP53(-/-) cells, compared to cells treated with BaP alone; (ii) ellipticine decreased CYP1A1 expression in TP53(+/+) cells in BaP co incubations; and (iii) cisplatin did not affect BaP-mediated CYP1A1 expression. Further, whereas cisplatin and etoposide had virtually no influence on CYP1A1 catalysed BaP metabolism, ellipticine treatment strongly inhibited BaP bioactivation. Our results indicate that the underlying mechanisms whereby etoposide and ellipticine regulate CYP1A1 expression must be different and may not be linked to p53 activation alone. These results could be relevant for smokers, who are exposed to increased levels of BaP, when prescribing chemotherapeutic drugs. Beside gene-environment interactions, more considerations should be given to potential drug-environment interactions during chemotherapy. PMID- 29471074 TI - Do humans still forage in an obesogenic environment? Mechanisms and implications for weight maintenance. AB - Many people struggle to control their food intake and bodyweight. This is often interpreted as evidence that humans are generally predisposed to consume food when it is available, because adiposity offered insurance against the threat of starvation in our ancestral environment. In this paper we suggest that modern humans have actually inherited a far broader range of foraging skills that continue to influence our dietary behaviour. To evaluate this idea, we identify three challenges that would need to be addressed to achieve efficient foraging; (1) monitoring the 'procurement cost' of foods, (2) determining the energy content of foods, and (3) proactively adapting to perceived food insecurity. In each case, we review evidence drawn from controlled and observational studies of contemporary humans and conclude that psychological mechanisms that address these challenges are conserved. For contemporary humans who live in fast-paced obesogenic environments, this foraging 'toolkit' no longer serves the same function to which it was adapted, and in many cases, this leads to an increase in food intake. Understanding these forms of 'evolutionary mismatch' is important because it can provide a stronger theoretical basis for informed dietary interventions that leverage fundamental foraging goals rather than work against them. PMID- 29471075 TI - Interspecific variation in avian thermoregulatory patterns and heat dissipation behaviours in a subtropical desert. AB - Deserts are physiologically challenging environments for birds, with scarce, unpredictable water resources combined with air temperatures (Tair) regularly exceeding avian body temperature (Tb). For arid-zone birds, mismatches between water supply and demand are a constant threat, yet interspecific variation in trade-offs between hyperthermia avoidance and dehydration avoidance remain poorly understood, particularly for free-ranging individuals. We examined behavioural and physiological responses to high Tair in nine species representing three orders that vary substantially in their heat dissipation thresholds, specifically pant50, the Tair at which panting behaviour is present in 50% of observations. Birds housed during mid-summer in large free-flight aviaries in the Kalahari Desert each received a surgically-implanted Tb logger, and we quantified shade seeking, activity and panting behaviours to examine relationships between species specific pant50 and Tb regulation. Overall, species setpoint Tb values were higher (range: 41.4 +/- 0.5 degrees C to 43.1 +/- 0.4 degrees C) than expected with maximum Tb values of 43.4-45.5 degrees C. Interspecific variation in Tb patterns at high Tair was substantial, with Tb increasing with Tair in most species, whereas in others no pattern or a negative relationship between Tb and Tair was evident. Most species avoided prolonged hyperthermia, with reductions in activity and increased shade-seeking evidently adequate to manage heat load without resorting to hyperthermia in in several of our study species. Access to drinking water and food resources in captivity may have affected Tb patterns. Our data reveal that thermoregulation varies substantially among species, and suggest that free-ranging birds in hot, arid environments may maintain higher Tb than currently thought. PMID- 29471076 TI - Daily pattern of energy distribution and weight loss. AB - Timing of energy intake, a temporal dietary pattern, may enhance health. Eating a greater amount of energy earlier and a smaller amount of energy later in the day, a behavioral circadian rhythm, may assist with chronoenhancement. Chronoenhancement seeks to enhance entrainment (synchronization) of biological and behavioral circadian rhythms. In humans, research reports that eating a greater amount of energy early and a smaller amount of energy later in the day increases dietary induced thermogenesis, improves cardiometabolic outcomes, and enhances weight loss. However, little human research has examined if this eating pattern enhances regularity of biological circadian rhythm. In a randomized controlled 8-week pilot study, the influence of energy distribution timing on weight loss and regularity of sleep onset and wake times (marker for biological circadian rhythm) was examined. Within an hypocaloric, three-meal prescription, participants (n = 8) were assigned to either: 1) Morning: 50%, 30%, and 20% of kcal at breakfast, lunch, and dinner, respectively; or 2) Evening: 20%, 30%, and 50% of kcal at breakfast, lunch, and dinner, respectively. Percent weight loss and regularity of sleep onset and wake times were significantly (p < 0.05) greater for Morning than Evening. To enhance understanding of the influence of energy distribution timing on health, longer studies conducted in free-living participants, with dietary intake assessed using time-stamped methods, that include measures of the circadian timing system are needed. This small review is based upon a symposium presentation at the Society of the Study of Ingestive Behavior in 2017.

AB - Reducing burst effects, providing controlled release, and safeguarding biologics against degradation are a few of several highly attractive applications for microgels in the field of controlled release. However, the incorporation of proteins into microgels without impairing stability is highly challenging. In this proof of concept study, the combination of microfluidics and thiol-ene photoclick chemistry was evaluated for the fabrication of antibody-loaded microgels with narrow size distribution. Norbornene-modified eight-armed poly(ethylene glycol) with an average molecular mass of 10,000 Da, 20,000 Da, or 40,000 Da were prepared as macromonomers for microgel formation. For functionalization, either hydrolytically cleavable ester or stable amide bonds were used. A microfluidic system was employed to generate precursor solution droplets containing macromonomers, the cross-linker dithiothreitol and the initiator Eosin-Y. Irradiation with visible light was used to trigger thiol-ene reactions which covalently cross-linked the droplets. For all bond-types, molecular masses, and concentrations gelation was very rapid (<20 s) and a plateau for the complex shear modulus was reached after only 5 min. The generated microgels had a rod-like shape and did not show considerable cellular toxicity. Stress conditions during the fabrication process were simulated and it could be shown that fabrication did not impair the activity of the model proteins lysozyme and bevacizumab. It was confirmed that the average hydrogel network mesh size was similar or smaller than the hydrodynamic diameter of bevacizumab which is a crucial factor for restricting diffusion and delaying release. Finally, microgels were loaded with bevacizumab and a sustained release over a period of 30 +/- 4 and 47 +/- 7 days could be achieved in vitro. PMID- 29471079 TI - Exploring the utility of "next-generation" sequence data on inferring the phylogeny of the South American Valeriana (Valerianaceae). AB - This study aimed to investigate the phylogenetic utility of genotyping-by sequencing (GBS) data in the southern South American subclade of Valerianaceae (Dipsacales). The variety of forms that has arisen in this clade, presumably over the past 5-10 million years, has all the signatures of an adaptive and rapid radiation. While the phylogeny of Valerianaceae has received a great deal of attention in the last decade, species relationships have been hard to resolve using traditional phylogenetic markers. Here, we collected high-throughput genomic sequence data from reduced-representation libraries obtained through GBS protocols. Putative orthologs were identified using within- and among-sample clustering using the computer software pyRAD. We recovered over 3000 loci for 14 species of southern South AmericanValeriana,with 140 loci present across all samples.We analyzed a set of phylogenetic trees generated from each locus using maximum likelihood methods, as well as multispecies coalescent (*BEAST) methods. For comparative purposes, we also used a supermatrix approach to infer the phylogeny for these taxa. Across different methods and data sets, we recovered consistent relationships for the southern South American valerians that we sampled with varying degrees of support. PMID- 29471081 TI - Schematic beliefs and problem solving performance predict depression in people experiencing persecutory delusions. AB - Depression occurring alongside psychosis is an important treatment target, both in its own right and as a potential maintenance factor for positive psychotic symptoms. The present paper reports a prospective longitudinal analysis of depression and its predictors over six months in a group of 60 participants experiencing persecutory delusions. We hypothesised that negative schematic beliefs about the self and problem solving difficulties would predict the persistence of depression over time. The results showed, as hypothesised, that more negative schematic beliefs about the self and poorer problem solving predicted higher depression scores six months later, beyond what could be predicted by baseline depression scores. These findings support a proposed role for schematic beliefs and problem solving difficulties in the perpetuation of depression occurring alongside psychosis, as has been substantiated for major depressive disorder. Interventionist research is warranted to confirm causal effects. PMID- 29471080 TI - Subjective age and risk of incident dementia: Evidence from the National Health and Aging Trends survey. AB - The present study examines the association between subjective age and risk of incident dementia in a large longitudinal sample of older adults. Participants were adults aged 65 years and older from the National Health and Aging Trends Study (NHATS). Subjective age, covariates, and cognitive status were assessed in 2011 and cognitive status was again assessed in 2012, 2013, 2014 and 2015. Incident dementia was determined based on answers from self and proxy respondents. The analyses included 4262 participants without dementia at baseline. Adjusting for demographic factors and baseline cognition, an older subjective age was related to higher likelihood of incident dementia. This association was partly accounted by depressive symptoms. Beyond the effect of chronological age, feeling older is associated with the risk of incident dementia. PMID- 29471078 TI - Development of controlled drug delivery systems for bone fracture-targeted therapeutic delivery: A review. AB - Impaired fracture healing is a major clinical problem that can lead to patient disability, prolonged hospitalization, and significant financial burden. Although the majority of fractures heal using standard clinical practices, approximately 10% suffer from delayed unions or non-unions. A wide range of factors contribute to the risk for nonunions including internal factors, such as patient age, gender, and comorbidities, and external factors, such as the location and extent of injury. Current clinical approaches to treat nonunions include bone grafts and low-intensity pulsed ultrasound (LIPUS), which realizes clinical success only to select patients due to limitations including donor morbidities (grafts) and necessity of fracture reduction (LIPUS), respectively. To date, therapeutic approaches for bone regeneration rely heavily on protein-based growth factors such as INFUSE, an FDA-approved scaffold for delivery of bone morphogenetic protein 2 (BMP-2). Small molecule modulators and RNAi therapeutics are under development to circumvent challenges associated with traditional growth factors. While preclinical studies has shown promise, drug delivery has become a major hurdle stalling clinical translation. Therefore, this review overviews current therapies employed to stimulate fracture healing pre-clinically and clinically, including a focus on drug delivery systems for growth factors, parathyroid hormone (PTH), small molecules, and RNAi therapeutics, as well as recent advances and future promise of fracture-targeted drug delivery. PMID- 29471082 TI - Anhedonic behavior and gamma-amino butyric acid during a sensitive period in female rats exposed to early adversity. AB - Early life adversity increases depressive behavior that emerges during adolescence. Sensitive periods have been associated with fewer GABAergic interneurons, especially parvalbumin (PV), brain derived growth factor, and its receptor, TrkB. Here, maternal separation (MS) and social isolation (ISO) were used to establish a sensitive period for anhedonic depression using the learned helplessness (LH) paradigm. Female Sprague-Dawley rat pups underwent MS for 4 h/day or received typical care (CON) between postnatal days 2-20; for the ISO condition, separate cohorts were individually housed between days 20-40 or served as controls (CON2). Anhedonia was defined by dichotomizing subjects into two groups based on one standard deviation of the mean number of escapes for the CON group (<14). This approach categorized 22% of CON subjects and 44% of MS subjects as anhedonic (p < 0.05), similar to the prevalence in maltreated human populations. Only 12.5% of ISO rats met criterion versus 28.5% in CON2 rats. Levels of PV and TrkB were reduced in the amygdala and prelimbic prefrontal cortex (PFC) in MS rats with <14 escapes, but elevated in behaviorally resilient MS rats (>13 escapes). The number of escapes in MS subjects significantly correlated with PV and TrkB levels (PFC: r = 0.93 and 0.91 and amygdala: r = 0.63 and 0.81, respectively; n = 9), but not in CON/ISO/CON2 subjects. Calretinin, but not calbindin, was elevated in the amygdala of MS subjects. These data suggest that low levels of PV and TrkB double the risk for anhedonia in females with an MS history compared to normal adolescent females.

AB - Zinc pyrithione is an active component incorporated in an extensive range of topically applied commercial products that are used worldwide. Despite its prevalence, no published study has investigated the penetration of zinc from the zinc pyrithione complex into human skin. Zinc is crucial for healthy skin function however an elevated concentration of labile zinc is toxic outside a narrow concentration range. Synchrotron X-ray fluorescence microscopy in conjunction with X-ray absorption near edge structure spectroscopy was used to map the deposition of zinc, quantitate the amount of zinc within the skin and to identify a change in the chemical form of zinc after application. This study has demonstrated a ~3.8 fold increase in zinc concentration within the viable epidermis (VE) after 24 h topical application of zinc pyrithione that increased significantly by ~250 fold after 48 h when compared to control skin. Confocal microscopy using a labile zinc specific dye, ZinPyr-1, showed that zinc pyrithione disrupted the skin cells zinc homeostasis and significantly increased the intracellular zinc concentration leading to cell toxicity. Overall, this study demonstrates that topical application of zinc pyrithione formulations leads to an increase in zinc penetration in human skin, consequently, raising concerns for potential localised toxicity to occur.

AB - ETHNOPHARMACOLOGICAL RELEVANCE: Hottuynia cordata is an important traditional Chinese medicine for the treatment of respiratory diseases including bacterial and viral infections. Polysaccharides isolated from Houttuynia cordata (HCP), as its main ingredients, have been demonstrated to ameliorate the LPS-induced acute lung injury in mice. The study aimed to determine the protective effects of HCP on multiple organ injury in influenza A virus (IAV) H1N1 infected mice and its primary mechanisms in anti-inflammation and immune regulation. MATERIALS AND METHODS: Mice were inoculated with IAV H1N1 and then treated with 20 or 40 mg/kg/d of HCP for survival test and acute lung-gut injury test. RESULTS: The treatment with HCP resulted in an increase in the survival rate of H1N1 infected mice and the protection from lung and intestine injury, accompanied with the reduced virus replication. HCP markedly decreased the concentration of pulmonary proinflammatory cytokines/chemokines and the number of intestinal goblet cells, and strengthened the intestinal physical and immune barrier, according to the increase of sIgA and tight junction protein (ZO-1) in intestine. At the same time, the inhibition of inflammation in lung and gut was related to the suppressing of the expression of TLR4 and p-NFkappaB p65 in lung. CONCLUSIONS: These results indicated that HCP ameliorated lung and intestine injury induced by IAV attack. The mechanisms were associated with inhibition of inflammation, protection of intestinal barrier and regulation of mucosal immunity, which may be related to the regulation of gut-lung axis. As an alternative medicine, HCP may have clinical potential to treat IAV infection in human beings. PMID- 29471086 TI - Gastroprotective effect of ethanol extracts of cladodes and roots of Pilosocereus gounellei (A. Weber ex K. Schum.) Bly. Ex Rowl (Cactaceae) on experimental ulcer models. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Pilosocereus gounellei Cactaceae), popularly known as "xique xique", is a species native from Caatinga region of Northeast Brazil, which is used by traditional communities in folk medicine for a variety of health problems, especially inflammatory processes and gastritis. AIM OF THE STUDY: The present study investigates the possible gastric antiulceractivity of ethanol extracts obtained from the cladodes and roots of Pilosocereus gounellei (EECPG and EERPG, respectively) and mechanisms of action underlying this effect. MATERIALS AND METHODS: Mice were used for the evaluation of the acute toxicity, and mice and rats to study the gastroprotective activity. The gastroprotective action of EECPG and EERPG was analyzed in the absolute ethanol in mice, ischemia reperfusion and cold restraint stress in rats. In the investigation of the gastroprotective mechanisms of EECPG and EERPG, the participation of the NO and prostaglandins, the levels of the non-protein sulfhydril groups (NP-SH) and the catalase activity using the ethanol-induced gastric mucosa lesion model and the quantification of the gastric mucus and the antisecretory activity through pylorus ligature model in rats were analyzed. RESULTS: The animals did not present any signs of acute toxicity for the EECPG and EERPG, and it was not possible to calculate the DL50. EECPG and EERPG (200 and 400 mg/kg) exhibited a significant gastroprotective effect in absolute ethanol, ischemia-reperfusion induced and cold restraint stress gastric lesion models. Gastroprotection of EECPG and EERPG (200 mg/kg) was significantly decreased in pre-treated mice with L-NAME. Our studies revealed that EECPG and EERPG (200 mg/kg) prevented the decrease of the non-protein sulfhydril groups (NPSH) and increased the catalase levels in ethanol-treated animals. However, the gastric secretion parameters (volume, [H+], pH) did not show any alteration. CONCLUSIONS: Our results indicate that the ethanolic extract from the cladodes and roots of Pilosocereus gounellei exhibits a significant gastroprotection, because it inhibits the formation of gastric lesions using different models. The participation of the nitric oxide, prostaglandins, the non-protein sulfhydril groups (NP-SH), catalase seem to be involved in the gastroprotection activity of the EECPG and EERPG. Nevertheless, this activity does not seem to be related to antisecretory mechanisms. PMID- 29471087 TI - Decontamination of Hg(II) from aqueous solution using polyamine-co-thiourea inarched chitosan gel derivatives. AB - Ethylenediamine (EDA), triethylenetetramine (TETA) and tetraethylenepentamine (TEPA) had been successfully introduced into the structure of thiourea (TC) modified chitosan (CS) by using formaldehyde as linkage, respectively. The resulted materials, TC-CS, TC-EDA-CS, TC-TETA-CS, and TC-TEPA-CS were characterized and employed as adsorbents in batch experiment for the Hg(II) removal. We have found the modification enhanced the Hg(II) adsorption significantly in comparison with raw CS. Hg(II) adsorption amounts for all adsorbents increased gradually and reached maxima at pH>=4.0. The adsorption of Hg(II) achieved an equilibrium state within 12h with the process drove by the pseudo-second-order model. The ionic strength had no remarkable inhibition effect on Hg(II) adsorption. While the Hg(II) adsorption capacities of the adsorbents were strongly related with the modifier types and the length of the incorporating amino ligands. Langmuir model described Hg(II) adsorption well with the maximum adsorption capacities of prepared adsorbents in order of TC-EDA-CS (217.1mg/g)>TC CS (164.8mg/g)>TC-TETA-CS (149.7mg/g)>TC-TEPA-CS (140.6mg/g) at room temperature. The FT-IR and XPS investigations implied that Hg(II) ion adsorption mechanism was characterized by a complexation reaction process. Adsorbents could be readily regenerated and had great reusability potential in Hg(II) ions capture from aqueous solution.

AB - A strain Leuconostoc citreum B-2 was isolated from homemade fermentation product of pineapple and its polysaccharide yield was 28.3g/L after cultivating the strain in Man-Rogosa-Sharpe (MRS) medium with 75g/L sucrose. The exopolysaccharide (EPS) was characterized by gas chromatography (GC), Fourier transform infrared (FT-IR) spectra, high-performance size-exclusion chromatography (HPSEC), nuclear magnetic resonance (NMR) spectroscopy and scanning electron microscope (SEM) analysis in present study. The monosaccharide composition of EPS was glucose and molecular weight was 3.77*106Da. FT-IR and NMR spectra revealed that the B-2 EPS was composed of 75% alpha-(1->6) linked d glucopyranose units existing in the main chain with 19% alpha-(1->3) branching and only a few alpha-(1->2) branching. The SEM of the dried EPS appeared irregular sheets with glittering surface and compact structure. Water solubility index and water holding capacity of B-2 EPS were 80% and 450%, respectively. All the mentioned characteristics suggested that the EPS has a potential application in the food, cosmetic and pharmaceuticals industry.

AB - This manuscript was focused on introducing a facile, green and scalable method to produce kappa-carrageenan (kappaC) hydrogel membranes containing in situ synthesized silver nanoparticles (AgNPs). In a typical protocol, kappaC hydrogels were obtained by heating (sol phase), followed by cooling (gel phase) the polysaccharide solution, which enabled the simultaneous synthesis of AgNPs during the heating time. The as synthesized AgNPs were characterized spectrophotometrically, and by dynamic light scattering and transmission electron microscopy. The swelling properties at different pH and the antimicrobial activity of kappaC-AgNP hydrogel were investigated. AgNPs were mostly spherical in shape, crystalline in nature and measuring ca. 27nm in diameter. The in situ synthesis of AgNPs changed the swelling properties of kappaC hydrogel and also reduces its viscosity and gelling temperature. The AgNPs were continuously released from kappaC hydrogel for up to 48h in a concentration sufficient to prevent the bacterial growth as confirmed by antimicrobial tests. The simplicity involved in the AgNPs synthesis combined to the good spreadability of kappaC hydrogel makes this method suitable for scale-up to manufacturing quantities of wound dressing.

WPMP-2 contained a complex branched structre formed by 1,2 linked alpha-d-Rhap, 1,2,4-linked alpha-d-Rhap, 1,3,5-linked alpha-l-Ara, 1,5- linked alpha-l-Araf, terminal alpha-l-Araf, 1,4-linked beta-d-Galp, 1,4-linked alpha-d-GalpA, and 4-linked alpha-d-GalpA. In vitro, WPMPs were of activation effect on splenocyte and macrophages, and could also protect immunocyte against 5 Fu induced immunosupression by restoring the proliferation rate, phagocytic index and cytokines secretion level. Moreover, the acid polysaccharide WPMP-2 exhibited better immunomodulatory activity than neutral polysaccharide WPMP-1, which indicated that the immunomodulatory activity of WPMPs were positively associated with higher content of uronic acid, percentage of rhamnose, arabinose and galactose, and branching degree. These findings could promote the polysaccharides from Polygonum multiflorum to be attractive functional food supplement and immunomodulatory adjuvant. PMID- 29471091 TI - Study of telomerase reverse transcriptase and uterine-ovarian-specific genes expression in the endometrial tissue of ovariectomized female Sprague-Dawley rats. AB - BACKGROUND: An in vivo study was carried out to study of telomerase reverse transcriptase and Uterine-Ovarian-specific genes expression in the endometrial tissue of ovariectomized female Sprague-Dawley rats. MATERIAL AND METHODS: Twenty four female Sprague-Dawley rats divided into 4 groups of six rats. The first and second groups were ovariectomized and given tamoxifen and tamoxifen-loaded SLN respectively for six days continuously. Group 3 served as the untreated ovariectomized control group and group 4 was made up of untreated normal healthy rats. At the end of the study, the rats were sacrificed and study of the genes expression and serum zinc and copper were carried out. RESULTS: The results showed that the expression of TERT in the group treated with tamoxifen, and tamoxifen-loaded solid lipid nanoparticles, significantly decreased (p<0.001) compared with ovariectomized control group. The results also revealed that the treatment with tamoxifen-loaded solid lipid nanoparticles increased expression of UO-44 gene compared to ovariectomized control group, while there was no difference between tamoxifen treated and control group. CONCLUSIONS: Encapsulation of tamoxifen in solid lipid nanoparticles increased its targeting efficiency and improved the impact of the drug on the serum levels of some trace elements.

AB - Balsamin, a type I ribosome-inactivating protein (RIP), has been shown to inhibit HIV-1 replication at the translation step. Our recent studies have shown that balsamin also possess anti-tumor, antibacterial and DNase-like activity, however, the amount of natural balsamin in Momordica balsamina seeds is limited and preclinical studies require large quantities of pure, bioactive balsamin. Therefore, in this study, we cloned the balsamin gene, expressed it in E.coli BL21 (DE3) strain and purified it by nickel affinity chromatography. Functional analysis indicated that balsamin exhibits both RNA N-glycosidase activity, releasing the Endo-fragment from rabbit reticulocyte rRNA, and DNase-like activity, converting the supercoiled form of a plasmid into the linear form in a concentration-dependent manner. Analysis of secondary structure revealed that recombinant balsamin mainly consisted of alpha-helical and random coiled with minimal turns and beta-sheets. Recombinant balsamin was found to be stable in the temperature range of 20-60 degrees C and pH range of 6-9. Antimicrobial assays showed that the minimum inhibitory concentrations of recombinant balsamin for various pathogens ranged between 1.56 and 12.5 MUg/ml. Heterologous expression and purification of balsamin carries great importance as it provides an alternative approach for large-scale preparation of biologically active recombinant balsamin, which is difficult from its natural source. PMID- 29471093 TI - Chemical cross-linked polyvinyl alcohol/cellulose nanocrystal composite films with high structural stability by spraying Fenton reagent as initiator. AB - Cross-linked polyvinyl alcohol (PVA) composite films with high structural stability were prepared by free radical copolymerization between cellulose nanocrystal (CNC) and maleic anhydride (MAH) modified PVA through spraying Fenton free radical as initiator. The influence of chemical cross-linked and physical network structure on mechanical, thermal and water absorption properties of the composite films were investigated. Compared to PVA and PVA/CNC composite film, significant improvements in the mechanical, thermal and water uptake properties of the cross-linked composite film were found. The tensile strength of the cross linked composite film was enhanced from 23.1MPa (neat PVA film) and 32.6MPa (PVA/CNC-10%) to 42.5MPa, and the maximum thermal degradation temperature was increased from 266.8 degrees C and 281.2 degrees C to 366.7 degrees C (cross linked composite film). Besides, the water absorption was reduced from 385.9% and 220.6% to 175.7% for cross-linked composite film. It indicates that compared with physical network structure in PVA/CNC composite film, the multiple cross-linked networks showed excellent thermal stability, resistance of water swelling and structural stability at the same CNC loading level. Thus, the PVA/CNC composite film with the multiple cross-linked network shows greater property reinforcements. PMID- 29471094 TI - Electrospinning of food-grade nanofibres from whey protein. AB - In this study, electrospinning has been employed to produce micro to nano scale fibres of whey protein in order to investigate their potential for use in the food industry. Initially, spinning of pure whey protein proved challenging; so in order to facilitate the spinning of freshly prepared aqueous solutions, small amounts of polyethylene oxide (as low as 1% w/w in solution) were incorporated in the spinning solutions. The electrospun composite polyethylene-oxide/whey fibres exhibited diameters in the region of 100 to 400 nm, showing the potential to build fibre bundles from this size up. Time-dependent examinations of pure whey protein aqueous solutions were conducted using rheometery and small angle neutron scattering techniques, with the results showing a substantial change in the solution properties with time and stirring; and allowing the production of fibres, albeit with large diameters, without the need for an additive. The spinability is related to the potential of the whey protein composites to form aggregate structures, either through hydration and interaction with neighbouring proteins, or through interaction with the polyethylene oxide. PMID- 29471095 TI - Proteomic of goat milk whey and its bacteriostatic and antitumour potential. AB - Goat whey is normally discarded in the milk processing industry. However, several studies have addressed its biological properties and possible use in human or animal diet. The present study aimed to analysis the protein profile of goat whey to evaluate its possible oxidant, antioxidant, antibacterial, antitumour, and cytotoxic activities in vitro against human erythrocytes. Goat whey was skimmed, and crude protein extract (CPE) was obtained. Next, protein fractions (F) were obtained using ammonium sulphate precipitation method. The proteins were characterized by SDS-PAGE, two-dimensional electrophoresis and soluble protein measurements. No significant differences were observed in protein profile of CPE, F 30-60% and F 60-90%. The highest protein content was found in F 60-90% (0.41mgP/mL). All samples, except F 0-30% showed bacteriostatic activity against different bacterial strains. Only CPE at a concentration of 1000MUg/mL was haemolytic against human erythrocytes. Oxidant activity against erythrocytes was not observed. Antioxidant activity was observed only for CPE. Cytotoxicity against C6 rat glioma cell line that was performed with CPE revealed tumour cell death>70% at concentrations of 0.05 and 0.1MUg/mL. These results demonstrate at first time that CPE may be used as an antioxidant, bacteriostatic and cytotoxic compound against tumour cells. PMID- 29471096 TI - Ionically crosslinked magnetic chitosan/kappa-carrageenan bioadsorbents for removal of anionic eriochrome black-T. AB - Magnetic bioadsorbents based on chitosan with different molecular weights were prepared. To stabilize under acidic condition the synthesized magnetic chitosan was crosslinked with kappa-carrageenan. The characterization of magnetic bioadsorbents revealed that the size of magnetic nanoparticles is affected by the chitosan molecular weight. Magnetic nanoparticles with larger sizes were obtained with the high molecular weight of chitosan. The removal of eriochrome black-T (EBT) by the magnetic bioadsorbents was investigated. The equilibrium adsorption isotherm data of EBT on bioadsorbents were found to be well explained through Langmuir isotherm model, from which the maximum adsorption capacities were found to be 280, 235, and 199mg/g for bioadsorbents prepared with low, medium, and high molecular weights of chitosan, respectively. A remarkable reduction in adsorption capacities of bioadsorbents was observed as the pH of dye solution was increased. The reduction in the dye adsorption under basic media suggested using a mild condition (pH=9) to recycle and reuse the bioadsorbents. Cyclic experiments indicated that current bioadsorbents can be effectively reused to remove anionic EBT from aqueous solutions. The removal efficiencies remained >93% even after five adsorption-desorption cycles, which suggest the present bioadsorbents as a great candidate in the wastewater treatment.

PMID- 29471098 TI - The role of effective connectivity between the task-positive and task-negative network for evidence gathering [Evidence gathering and connectivity]. AB - Reports linking a 'jumping-to-conclusions' bias to delusions have led to growing interest in the neurobiological correlates of probabilistic reasoning. Several brain areas have been implicated in probabilistic reasoning; however, findings are difficult to integrate into a coherent account. The present study aimed to provide additional evidence by investigating, for the first time, effective connectivity among brain areas involved in different stages of evidence gathering. We investigated evidence gathering in 25 healthy individuals using fMRI and a new paradigm (Box Task) designed such as to minimize the effects of cognitive effort and reward processing. Decisions to collect more evidence ('draws') were contrasted to decisions to reach a final choice ('conclusions') with respect to BOLD activity. Psychophysiological interaction analysis was used to investigate effective connectivity. Conclusion events were associated with extensive brain activations in widely distributed brain areas associated with the task-positive network. In contrast, draw events were characterized by higher activation in areas assumed to be part of the task-negative network. Effective connectivity between the two networks decreased during draws and increased during conclusion events. Our findings indicate that probabilistic reasoning may depend on the balance between the task-positive and task-negative network, and that shifts in connectivity between the two may be crucial for evidence gathering. Thus, abnormal connectivity between the two systems may significantly contribute to the jumping-to-conclusions bias. PMID- 29471099 TI - The dynamics of error processing in the human brain as reflected by high-gamma activity in noninvasive and intracranial EEG. AB - Error detection in motor behavior is a fundamental cognitive function heavily relying on local cortical information processing. Neural activity in the high gamma frequency band (HGB) closely reflects such local cortical processing, but little is known about its role in error processing, particularly in the healthy human brain. Here we characterize the error-related response of the human brain based on data obtained with noninvasive EEG optimized for HGB mapping in 31 healthy subjects (15 females, 16 males), and additional intracranial EEG data from 9 epilepsy patients (4 females, 5 males). Our findings reveal a multiscale picture of the global and local dynamics of error-related HGB activity in the human brain. On the global level as reflected in the noninvasive EEG, the error related response started with an early component dominated by anterior brain regions, followed by a shift to parietal regions, and a subsequent phase characterized by sustained parietal HGB activity. This phase lasted for more than 1 s after the error onset. On the local level reflected in the intracranial EEG, a cascade of both transient and sustained error-related responses involved an even more extended network, spanning beyond frontal and parietal regions to the insula and the hippocampus. HGB mapping appeared especially well suited to investigate late, sustained components of the error response, possibly linked to downstream functional stages such as error-related learning and behavioral adaptation. Our findings establish the basic spatio-temporal properties of HGB activity as a neural correlate of error processing, complementing traditional error-related potential studies. PMID- 29471101 TI - On object selectivity and the anatomy of the human fusiform gyrus. AB - pFs is a functionally-defined region in the human brain that is involved in recognizing objects. A recent trend refers to pFs as the posterior fusiform sulcus, which is a neuroanatomical structure that does not exist. Here, we correct this mistake. To achieve this goal, we first recount the original definitions of pFs and then review the identification of sulci within and surrounding the fusiform gyrus (FG) including the mid-fusiform sulcus (MFS), which is a tertiary sulcus within the FG. We highlight that tertiary sulci, such as the MFS, are often absent from brain atlases, which complicates the accurate localization of functional regions, as well as the understanding of structural functional relationships in ventral temporal cortex (VTC). When considering the location of object-selective pFs from previously published data relative to the sulci surrounding the FG, as well as the MFS, we illustrate that (1) pFs spans several macroanatomical structures, which is consistent with the original definitions of pFs (Grill-Spector et al., 1999, 2000), and (2) the topological relationship between pFs and MFS has both stable and variable features. To prevent future confusion regarding the anatomical location of functional regions within VTC, as well as to complement tools that automatically identify sulci surrounding the FG, we provide a method to automatically identify the MFS in individual brains using FreeSurfer. Finally, we highlight the benefits of using cortical surface reconstructions in large datasets to identify and quantify tertiary sulci compared to classic dissection methods because the latter often fail to differentiate tertiary sulci from shallow surface indentations produced by veins and arteries. Altogether, we propose that the inclusion of definitions and labels for tertiary sulci in neuroanatomical atlases and neuroimaging software packages will enhance understanding of functional-structural relationships throughout the human brain. PMID- 29471100 TI - Dynamic fMRI networks predict success in a behavioral weight loss program among older adults. AB - More than one-third of adults in the United States are obese, with a higher prevalence among older adults. Obesity among older adults is a major cause of physical dysfunction, hypertension, diabetes, and coronary heart diseases. Many people who engage in lifestyle weight loss interventions fail to reach targeted goals for weight loss, and most will regain what was lost within 1-2 years following cessation of treatment. This variability in treatment efficacy suggests that there are important phenotypes predictive of success with intentional weight loss that could lead to tailored treatment regimen, an idea that is consistent with the concept of precision-based medicine. Although the identification of biochemical and metabolic phenotypes are one potential direction of research, neurobiological measures may prove useful as substantial behavioral change is necessary to achieve success in a lifestyle intervention. In the present study, we use dynamic brain networks from functional magnetic resonance imaging (fMRI) data to prospectively identify individuals most likely to succeed in a behavioral weight loss intervention. Brain imaging was performed in overweight or obese older adults (age: 65-79 years) who participated in an 18-month lifestyle weight loss intervention. Machine learning and functional brain networks were combined to produce multivariate prediction models. The prediction accuracy exceeded 95%, suggesting that there exists a consistent pattern of connectivity which correctly predicts success with weight loss at the individual level. Connectivity patterns that contributed to the prediction consisted of complex multivariate network components that substantially overlapped with known brain networks that are associated with behavior emergence, self-regulation, body awareness, and the sensory features of food. Future work on independent datasets and diverse populations is needed to corroborate our findings. Additionally, we believe that efforts can begin to examine whether these models have clinical utility in tailoring treatment. PMID- 29471102 TI - High fructose diet-induced metabolic syndrome: Pathophysiological mechanism and treatment by traditional Chinese medicine. AB - Fructose is a natural monosaccharide broadly used in modern society. Over the past few decades, epidemiological studies have demonstrated that high fructose intake is an etiological factor of metabolic syndrome (MetS). This review highlights research advances on fructose-induced MetS, especially the underlying pathophysiological mechanism as well as pharmacotherapy by traditional Chinese medicine (TCM), using the PubMed, Web of science, China National Knowledge Infrastructure, China Science and Technology Journal and Wanfang Data. This review focuses on de novo lipogenesis (DNL) and uric acid (UA) production, two unique features of fructolysis different from glucose glycolysis. High level of DNL and UA production can result in insulin resistance, the key pathological event in developing MetS, mostly through oxidative stress and inflammation. Some other pathologies like the disturbance in brain and gut microbiota in the development of fructose-induced MetS in the past years, are also discussed. In management of MetS, TCM is an excellent representative in alternative and complementary medicine with a complete theory system and substantial herbal remedies. TCMs against MetS or MetS components, including Chinese patent medicines, TCM compound formulas, single TCM herbs and active compounds of TCM herbs, are reviewed on their effects and molecular mechanisms. TCMs with hypouricemic activity, which specially target fructose-induced MetS, are highlighted. And new technologies and strategies (such as high-throughput assay and systems biology) in this field are further discussed. In summary, fructose induced MetS is a multifactorial disorder with the underlying complex mechanisms. Current clinical and pre-clinical evidence supports the potential of TCMs in management of MetS. Additionally, TCMs may show some advantages against complex MetS as their holistic feature through multiple target actions. However, further work is needed to confirm the effectivity and safety of TCMs by high-standard clinical trials, clarify the molecular mechanisms, and develop new anti-MetS drugs by development and application of optimized and feasible strategies and methods. PMID- 29471103 TI - Embelin and its derivatives unravel the signaling, proinflammatory and antiatherogenic properties of GPR84 receptor. AB - GPR84 is an orphan G-protein coupled receptor, expressed on monocytes, macrophages and neutrophils and is significantly upregulated by inflammatory stimuli. The physiological role of GPR84 remains largely unknown. Medium chain fatty acids (MCFA) activate the receptor and have been proposed to be its endogenous ligands, although the high concentrations of MCFAs required for receptor activation generally exceed normal physiological levels. We identified the natural product embelin as a highly potent and selective surrogate GPR84 agonist (originally disclosed in patent application WO2007027661A2, 2007) and synthesized close structural analogs with widely varying receptor activities. These tools were used to perform a comprehensive study of GPR84 signaling and function in recombinant cells and in primary human macrophages and neutrophils. Activation of recombinant GPR84 by embelin in HEK293 cells results in Gi/o as well as G12/13-Rho signaling. In human macrophages, GPR84 initiates PTX sensitive Erk1/2 and Akt phosphorylation, PI-3 kinase activation, calcium flux, and release of prostaglandin E2. In addition, GPR84 signaling in macrophages elicits Gi Gbetagamma-mediated augmentation of intracellular cAMP, rather than the decrease expected from Gialpha engagement. GPR84 activation drives human neutrophil chemotaxis and primes them for amplification of oxidative burst induced by FMLP and C5A. Loss of GPR84 is associated with attenuated LPS-induced release of proinflammatory mediators IL-6, KC-GROalpha, VEGF, MIP-2 and NGAL from peritoneal exudates. While initiating numerous proinflammatory activities in macrophages and neutrophils, GPR84 also possesses GPR109A-like antiatherosclerotic properties in macrophages. Macrophage receptor activation leads to upregulation of cholesterol transporters ABCA1 and ABCG1 and stimulates reverse cholesterol transport. These data suggest that GPR84 may be a target of therapeutic value and that distinct modes of receptor modulation (inhibition vs. stimulation) may be required for inflammatory and atherosclerotic indications. PMID- 29471104 TI - Cellular senescence as a therapeutic target to improve renal transplantation outcome. AB - Kidney transplants from aged donors are more vulnerable to ischemic injury, suffer more from delayed graft function and have a lower graft survival compared to kidneys from younger donors. On a cellular level, aging results in an increase in cells that are in a permanent cell cycle arrest, termed senescence, which secrete a range of pro-inflammatory cytokines and growth factors. Consequently, these senescent cells negatively influence the local milieu by causing inflammaging, and by reducing the regenerative capacity of the kidney. Moreover, the oxidative damage that is inflicted by ischemia-reperfusion injury during transplantation can induce senescence and accelerate aging. In this review, we describe recent developments in the understanding of the biology of aging that have led to the development of a new class of therapeutic agents aimed at eliminating senescent cells. These compounds have already shown to be able to restore tissue homeostasis in old mice, improve kidney function and general health- and lifespan. Use of these anti-senescence compounds holds great promise to improve the quality of marginal donor kidneys as well as to remove senescent cells induced by ischemia-reperfusion injury. Altogether, senescent cell removal may increase the donor pool, relieving the growing organ shortage and improve long-term transplantation outcome. PMID- 29471105 TI - Icariin doped bioactive glasses seeded with rat adipose-derived stem cells to promote bone repair via enhanced osteogenic and angiogenic activities. AB - AIMS: Cell communication between mesenchymal stem cells and blood vessel cells are crucial for bone repair. We have previously shown that the phyto-molecule icariin significantly promoted osteogenic differentiation of rat adipose-derived stem cells (ASCs). In the present study, we aimed to investigate the relationship between icariin induced osteogenic differentiation of ASCs and angiogenesis of rat endothelial progenitor cells (EPCs). Besides, we used icariin doped 45S5 Bioglass seeded with ASCs to promote bone healing in rat calvarial bone defect models. MAIN METHODS: The conditioned medium from undifferentiated ASCs (ASCs-CM) and icariin induced ASCs (Icariin-ASCs-CM) was obtained and the vascular endothelial growth factor (VEGF) protein secretion level was measured. The angiogenic capacity and molecular mechanism of ASC-CM and Icariin-ASCs-CM on rat EPCs was analyzed. Rat calvarial bone defect models were established and treated with scaffolds implantation. Micro-CT imaging, histological and immunohistological staining were performed on the isolated specimens at 12 weeks post-surgery. KEY FINDINGS: VEGF protein expression was significantly increased after icariin treatment with the highest expression in the 10-7 M icariin group. Icariin-ASCs-CM obviously increased the angiogenesis of rat EPCs and this capacity was inhibited by a VEGF/VEGF receptor-specific binding inhibitor bevacizumab. Results of the in vivo investigations showed that all scaffolds promoted bone healing compared to the Control group. Icariin significantly improved the healing capacity of 45S5 Bioglass seeded with ASCs. SIGNIFICANCE: Implantation of Icariin/45S5 Bioglass seeded with rat ASCs could obviously promote both osteogenesis and angiogenesis and therefore represents an ideal candidate bone substitutes for bone repair and regeneration. PMID- 29471106 TI - Historical and contemporary features of infections due to Clostridium novyi. AB - Clostridium novyi is an anaerobic bacterium that resides in the soil in nature and that may cause severe clinical infections in humans. It is named after Frederick Novy, who incidentally discovered the anaerobic organism responsible for septicemia in rabbits. In this paper, we explore the circumstances surrounding the identification of the organism. In particular, we address who Novy was and what he was trying to do when he first described the organism in the 1890s. We then address what is known about the biological features of the organism today, as well as the clinical syndromes that are now recognized to be associated with the microbe. Finally, we review efforts that have been made to use the organism for potential beneficial purposes for humans. PMID- 29471107 TI - PICK1 deficiency exacerbates sepsis-associated acute lung injury and impairs glutathione synthesis via reduction of xCT. AB - The role of oxidative stress has been well documented in the development of sepsis-induced acute lung injury (ALI). Protein interaction with C-kinase 1 (PICK1) participates in oxidative stress-related neuronal diseases. However, its function in lung infections and inflammatory diseases is not known. We therefore sought to investigate whether PICK1 is involved in sepsis-induced ALI. Cecal ligation and puncture (CLP) was performed in anesthetized wild type (WT) and PICK1 knock out (KO, PICK1-/-) mice with C57BL/6 background. At the time of CLP, mice were given fluid resuscitation. Mouse lungs were harvested at 24 and 72 h for Western blot analysis, qRT-PCR, BALF analysis, Hematoxylin and Eosin staining, TUNEL staining, maleimide staining, flow cytometry analysis, GCL, GSH, GSSG and cysteine levels measurement. A marked elevation of PICK1 mRNA and protein level were demonstrated in lung tissue, which was accompanied by increased production of reactive oxygen species (ROS) and reactive nitrogen species (RNS) and consumption of glutathione (GSH). N-acetylcysteine (NAC), buthionine sulfoximine (BSO) and GSH-monoethyl ester (GSH-MEE) were injected into mice via caudal vein to regulate glutathione (GSH) level in lung. Alterations of lung GSH content induced PICK1 level change after CLP challenge. In PICK1-/- underwent with CLP, lung injury and survival were significantly aggravated compared with wild-type mice underwent with CLP. Concomitantly, CLP-induced lung cell apoptosis was exacerbated in PICK1-/- mice. The level of xCT, other than PKCalpha, in lung tissue was significantly lowered in PICK1-/- but not in wild type that underwent CLP surgery. Meanwhile, Nrf2 activation, which dominating xCT expression, was inhibited in PICK1-/- but not in wild type mice that underwent CLP surgery, as well. Moreover, higher level of PICK1 was detected in PBMCs of septic patients than healthy controls. Taken together, PICK1 plays a pivotal role in sepsis-induced ALI by regulating GSH synthesis via affecting the substrate specific subunit of lung cystine/glutamate transporter, xCT. PMID- 29471108 TI - Redox stress in Marfan syndrome: Dissecting the role of the NADPH oxidase NOX4 in aortic aneurysm. AB - Marfan syndrome (MFS) is characterized by the formation of ascending aortic aneurysms resulting from altered assembly of extracellular matrix fibrillin containing microfibrils and dysfunction of TGF-beta signaling. Here we identify the molecular targets of redox stress in aortic aneurysms from MFS patients, and investigate the role of NOX4, whose expression is strongly induced by TGF-beta, in aneurysm formation and progression in a murine model of MFS. Working models included aortae and cultured vascular smooth muscle cells (VSMC) from MFS patients, and a NOX4-deficient Marfan mouse model (Fbn1C1039G/+-Nox4-/-). Increased tyrosine nitration and reactive oxygen species levels were found in the tunica media of human aortic aneurysms and in cultured VSMC. Proteomic analysis identified nitrated and carbonylated proteins, which included smooth muscle alpha actin (alphaSMA) and annexin A2. NOX4 immunostaining increased in the tunica media of human Marfan aorta and was transcriptionally overexpressed in VSMC. Fbn1C1039G/+-Nox4-/- mice aortas showed a reduction of fragmented elastic fibers, which was accompanied by an amelioration in the Marfan-associated enlargement of the aortic root. Increase in the contractile phenotype marker calponin in the tunica media of MFS mice aortas was abrogated in Fbn1C1039G/+-Nox4-/- mice. Endothelial dysfunction evaluated by myography in the Marfan ascending aorta was prevented by the absence of Nox4 or catalase-induced H2O2 decomposition. We conclude that redox stress occurs in MFS, whose targets are actin-based cytoskeleton members and regulators of extracellular matrix homeostasis. Likewise, NOX4 have an impact in the progression of the aortic dilation in MFS and in the structural organization of the aortic tunica media, the VSMC phenotypic modulation, and endothelial function. PMID- 29471109 TI - Extensively drug-resistant Acinetobacter baumannii bacteraemia in a multidisciplinary intensive care unit during a 6-year period: Risk factors for fulminant sepsis. AB - OBJECTIVES: This study aimed to determine potential host-, pathogen-, infection- and treatment-related risk factors that might predict a fulminant fatal course of bacteraemia caused by extensively drug-resistant Acinetobacter baumannii (XDR Aba). METHODS: Eighty-seven patients with monomicrobial growth of XDR-Aba in blood cultures within a 6-year period (2011-2016) were studied. Patients were divided into three groups according to ICU outcome: Group A (n=40) consisted of patients who survived; Group B (n=10) included patients with fulminant sepsis who died early (<=48h); and Group C (n=37) included patients who died later (>48h) after the onset of bacteraemia. RESULTS: Regarding patient co-morbidities, patients who died from fulminant XDR-Aba bacteraemia had a significantly higher prevalence of chronic renal failure compared with patients who survived (40.0% vs. 7.5%; P=0.029). Patients with fulminant sepsis showed more severe organ dysfunction based on SOFA score compared with survivors (10.83+/-2.93 vs. 6.65+/ 3.6; P=0.013). The primary to secondary bacteraemia ratio and appropriate treatment were similar among the three outcome groups. Patients with fulminant bacteraemia displayed higher rates of colistin-, tigecycline- and pandrug resistant strains, although not statistically significant. CONCLUSIONS: Patients suffering from a fulminant course of XDR-Aba bacteraemia showed significantly higher rates of chronic renal failure and multiple organ dysfunction. Resistance patterns of XDR-Aba isolates and receipt of appropriate treatment did not affect outcomes. Further studies including larger samples of patients along with investigation of specific virulence determinants of individual Aba strains are needed. PMID- 29471110 TI - Antagonistic and synergistic interactions during the binding of binary mixtures of polycyclic aromatic hydrocarbons to the aryl hydrocarbon receptor. AB - In order to assess the potential of polycyclic aromatic hydrocarbons (PAHs) to interact with each other, benzo(a)pyrene (B(a)P) was incubated either alone or in combination with other isomeric 5-ring PAHs in precision-cut rat liver slices. At the end of the incubation, the slices were removed and the O-deethylation of ethoxyresorufin (EROD) was determined in microsomal preparations. The BP-mediated rise in EROD activity was suppressed in the presence of dibenzo(a,j)anthracene, dibenzo(a,c)anthracene and picene, whereas it was increased in the presence of pentacene. In the case of benzo(b)chrysene, benzo(c)chrysene and benzo(g)chrysene the effect was concentration-dependent with both antagonism and synergism being observed. The binding of B(a)P to the aryl hydrocarbon (Ah) receptor was similarly modulated by other PAHs. No correlation was evident between binding avidity of the PAH to the Ah receptor and either its potential for interaction or nature of interaction, e.g. synergism or antagonism. These interactions were also independent of the molecular shape (ring arrangement) of the 5-ring isomeric PAHs. Bearing in mind the role of the Ah receptor in chemical carcinogenesis, it may be concluded that interactions at the Ah receptor site may contribute to the well-established modulation of the carcinogenicity of one PAH in the presence of another. PMID- 29471111 TI - Mortality prediction in intensive care units (ICUs) using a deep rule-based fuzzy classifier. AB - Electronic health records (EHRs) contain critical information useful for clinical studies. Early assessment of patients' mortality in intensive care units is of great importance. In this paper, a Deep Rule-Based Fuzzy System (DRBFS) was proposed to develop an accurate in-hospital mortality prediction in the intensive care unit (ICU) patients employing a large number of input variables. Our main contribution is proposing a system, which is capable of dealing with big data with heterogeneous mixed categorical and numeric attributes. In DRBFS, the hidden layer in each unit is represented by interpretable fuzzy rules. Benefiting the strength of soft partitioning, a modified supervised fuzzy k-prototype clustering has been employed for fuzzy rule generation. According to the stacked approach, the same input space is kept in every base building unit of DRBFS. The training set in addition to random shifts, obtained from random projections of prediction results of the current base building unit is presented as the input of the next base building unit. A cohort of 10,972 adult admissions was selected from Medical Information Mart for Intensive Care (MIMIC-III) data set, where 9.31% of patients have died in the hospital. A heterogeneous feature set of first 48 h from ICU admissions, were extracted for in-hospital mortality rate. Required preprocessing and appropriate feature extraction were applied. To avoid biased assessments, performance indexes were calculated using holdout validation. We have evaluated our proposed method with several common classifiers including naive Bayes (NB), decision trees (DT), Gradient Boosting (GB), Deep Belief Networks (DBN) and D-TSK FC. The area under the receiver operating characteristics curve (AUROC) for NB, DT, GB, DBN, D-TSK-FC and our proposed method were 73.51%, 61.81%, 72.98%, 70.07%, 66.74% and 73.90% respectively. Our results have demonstrated that DRBFS outperforms various methods, while maintaining interpretable rule bases. Besides, benefiting from specific clustering methods, DRBFS can be well scaled up for large heterogeneous data sets. PMID- 29471112 TI - Evaluation of Two Commercial Real-Time PCR Kits for Aspergillus DNA Detection in Bronchoalveolar Lavage Fluid in Patients with Invasive Pulmonary Aspergillosis. AB - Invasive pulmonary aspergillosis (IPA) is a common complication of immunosuppression. Rapid diagnosis using molecular techniques is essential to improve patient survival. PCR techniques are promising in enhancing Aspergillus detection in blood and respiratory samples. We evaluate for the first time the performances of two commercial real-time PCR kits, the A. fumigatus Bio-Evolution and the MycoGENIE A. fumigatus for the detection of A. fumigatus DNA in bronchoalveolar lavage (BAL) from patients with and without IPA. Seventy-three BAL samples were included. Thirty-one of them corresponded to patients with probable IPA, 11 to patients with possible IPA, and 31 to patients without aspergillosis, according to the 2008 European Organization for Research and Treatment of Cancer/Mycoses Study Group criteria. In the probable IPA group, A. fumigatus Bio-Evolution and the MycoGENIE A. fumigatus real-time PCR kits showed a specificity of 100% and a sensitivity of 81% and 71%, respectively. The A. fumigatus Bio-Evolution detected Aspergillus DNA in the 14 BAL samples with a positive Aspergillus culture result, whereas the MycoGENIE A. fumigatus PCR result was positive only for 12. In the possible IPA group, there were no positive real-time PCR or positive Aspergillus culture results. For the patients without aspergillosis, no positive result was observed for real-time PCR kit, despite the presence of various other non-Aspergillus pathogens in this group. Our study demonstrates an excellent specificity and a good sensitivity of A. fumigatus DNA detection in BAL samples with both kits. PMID- 29471113 TI - Validation of a Customized Bioinformatics Pipeline for a Clinical Next-Generation Sequencing Test Targeting Solid Tumor-Associated Variants. AB - Bioinformatic analysis is an integral and critical part of clinical next generation sequencing. It is especially challenging for some pipelines to consistently identify insertions and deletions. We present the validation of an open source tumor amplicon pipeline (OTA-pipeline) for clinical next-generation sequencing targeting solid tumor-associated variants. Raw data generated from 557 TruSight Tumor 26 samples and in silico data were analyzed by the OTA-pipeline and legacy pipeline and compared. Discrepant results were confirmed by orthogonal methods. The OTA-pipeline reported 22 variants that were not detected by the previously validated pipeline, including seven synonymous or intronic single nucleotide variants, five single-nucleotide variants at frequency <5%, one insertion, and nine deletions. Variant allele frequencies reported by the two pipelines were highly concordant, although a few significant discrepancies were present. Analysis of in silico FASTQ files demonstrated a higher sensitivity of detecting complex insertions and deletions with the OTA-pipeline. The higher sensitivity came at a cost, because false-positive calls were increased in difficult-to-sequence regions. However, these calls were all flagged by our strand bias filter, distinguishing them from true variants. Our validation process provides a model for laboratories that want to establish an in-house bioinformatics pipeline for clinical next-generation sequencing. PMID- 29471114 TI - Reference Size Matching, Whole-Genome Amplification, and Fluorescent Labeling as a Method for Chromosomal Microarray Analysis of Clinically Actionable Copy Number Alterations in Formalin-Fixed, Paraffin-Embedded Tumor Tissue. AB - Cancer genome copy number alterations (CNAs) assist clinicians in selecting targeted therapeutics. Solid tumor CNAs are most commonly evaluated in formalin fixed, paraffin-embedded (FFPE) tissue by fluorescence in situ hybridization. Although fluorescence in situ hybridization is a sensitive and specific assay for interrogating preselected genomic regions, it provides no information about coexisting clinically significant copy number changes. Chromosomal microarray analysis is an alternative DNA-based method for interrogating genome-wide CNAs in solid tumors. However, DNA extracted from FFPE tumor tissue produces an essential, yet problematic, sample type. The College of American Pathologists/American Society of Clinical Oncology guidelines for optimal tumor tissue handling, published in 2007 for breast cancer and in 2016 for gastroesophageal adenocarcinomas, are lacking for other solid tumors. Thus, cold ischemia times are seldom monitored in non-breast cancer and non-gastroesophageal adenocarcinomas, and all tumor biospecimens are affected by chemical fixation. Although intended to preserve specimens for long-term storage, formalin fixation causes loss of genetic information through DNA damage. Herein, we describe a reference size matching, whole-genome amplification, and fluorescent labeling method for FFPE-derived DNA designed to improve chromosomal microarray results from suboptimal nucleic acids and salvage highly degraded samples. With this technological advance, whole-genome copy number analysis of tumor DNA can be reliably performed in the clinical laboratory for a wide variety of tissue conditions and tumor types. PMID- 29471115 TI - Targeted Next-Generation Sequencing Is a Sensitive Tool for Differential Diagnosis of Myelodysplastic Syndromes in Bone Marrow Trephines. AB - Myelodysplastic syndromes are hematological neoplasias in which immunohistologic examination of bone marrow trephines is important for a definite diagnosis. Unequivocal distinction from reactive bone marrow changes is, however, sometimes difficult. Because neoplastic clones in myelodysplastic syndrome carry mutations in recurrent genes, mutation detection by targeted next-generation sequencing may be a useful support for differential diagnosis. To elucidate the accuracy of this approach in the clinical diagnostic setting, we analyzed single and consecutive bone marrow trephines processed for immunohistologic examination from 145 patients by targeted next-generation sequencing of 12 genes recurrently mutated in myelodysplastic syndromes. Of 110 patients with immunohistologic unequivocal diagnosis, 41 of 47 with myelodysplastic syndrome carried mutations. In 14 consecutive samples available from these patients, remissions were accompanied by loss of mutations and ongoing disease with persisting mutations. Of 35 samples with indefinite immunohistologic appearance, 22 developed clinical unequivocal myelodysplastic syndrome in the further course, and 19 carried mutations already in the initial biopsy, which persisted in consecutive samples available from 13 patients. No mutation was detected in any initial and consecutive sample of 13 patients with indefinite immunohistologic appearance without clinical unequivocal myelodysplastic syndrome in the further course. We conclude that targeted next generation sequencing is an accurate tool for differential diagnosis of myelodysplastic syndrome in the clinical diagnostic setting.

AB - Here we report the first clinical Escherichia coli isolate co-harboring mcr-1, blaKPC-2 and two copies of fosA3 from China. The five plasmids of the isolate were completely sequenced and analyzed. Gene mcr-1 and blaKPC-2 were located on IncI2 and IncR plasmid, respectively. A variety of other resistance determinants such as fosA3 (two copies), blaCTX-M-123, blaOXA-1 and blaCTX-M-65 were also identified from the rest plasmids. PMID- 29471116 TI - Genetic populations and virulence factors of Helicobacter pylori. AB - Helicobacter pylori is a bacterium that has infected more than half of the human population worldwide. This bacterium is closely associated with serious human diseases, such as gastric cancer, and identifying and understanding factors that predict bacterial virulence is a priority. In addition, this pathogen shows high genetic diversity and co-evolution with human hosts. H. pylori population genetics, therefore, has emerged as a tool to track human demographic history. As the number of genome sequences available is increasing, studies on the evolution and virulence of H. pylori are gaining momentum. This review article summarizes the most recent findings on H. pylori virulence factors and population genetics. PMID- 29471118 TI - The dynamics of norovirus genotypes and genetic analysis of a novel recombinant GII.P12-GII.3 among infants and children in Bangkok, Thailand between 2014 and 2016. AB - Norovirus (NoV) is the leading cause of viral acute gastroenteritis among all age groups in the world. We performed a molecular epidemiological study of the NoVs prevalent in Bangkok between November 2014 and July 2016 to investigate the emergence of new NoV variants in Thailand. A total of 332 stool specimens were collected from hospitalized pediatric patients with acute gastroenteritis in Bangkok, Thailand. NoVs were detected by real-time PCR. The genome of the N terminal/shell domain was amplified, the nucleotide sequence was determined, and phylogenetic analyses were performed. GII NoV was detected in 58 (17.5%) of the 332 specimens. GII.17, a genotype strain prevalent from 2014 to mid-2015, was hardly detected and replaced by the GII.3 genotype strain. Entire genome sequencing followed by phylogenetic analysis of the GII.3 genotype strains indicated that they are new recombinant viruses, because the genome encoding ORF1 is derived from a GII.12 genotype strain, whereas that encoding ORF2-3 is from a GII.3 genotype strain. The putative recombination breakpoints with the highest statistical significance were located around the border of 3Dpol and ORF2. The change in the prevalent strain of NoV seems to be linked to the emergence of new forms of recombinant viruses. These findings suggested that the swapping of the structural and non-structural proteins of NoV is a common mechanism by which new epidemic variants are generated in nature. PMID- 29471119 TI - Enediynes bearing polyfluoroaryl sulfoxide as new antiproliferative agents with dual targeting of microtubules and DNA. AB - A novel series of enediynes possessing pentafluorophenylsulfoxide have been developed. The innovative compounds possess antiproliferative activity against a broad panel of human cancer cells originating from breast, blood, lung, kidney, colon, prostate, pancreas or skin with IC50 ranging from 0.6 to 3.4 MUM. The antiproliferative activity of enediynes in darkness is associated to their ability to compromise microtubule network. In addition, exposure to UV leads to double-stranded DNA cleavage caused by the newly synthesized molecules reducing further their IC50 in nanomolar range against human tumor cells, including chemo resistant pancreatic cancer cells. Taken together, the examined data demonstrate that enediynes possessing pentafluorosulfoxide are promising molecules in the cancer therapy. PMID- 29471120 TI - The 4-N-acyl and 4-N-alkyl gemcitabine analogues with silicon-fluoride-acceptor: Application to 18F-Radiolabeling. AB - The coupling of gemcitabine with functionalized carboxylic acids using peptide coupling conditions afforded 4-N-alkanoyl analogues with a terminal alkyne or azido moiety. Reaction of 4-N-tosylgemcitabine with azidoalkyl amine provided 4-N alkyl gemcitabine with a terminal azido group. Click reaction with silane building blocks afforded 4-N-alkanoyl or 4-N-alkyl gemcitabine analogues suitable for fluorination. RP-HPLC analysis indicated better chemical stability of 4-N alkyl gemcitabine analogues versus 4-N-alkanoyl analogues in acidic aqueous conditions. The 4-N-alkanoyl gemcitabine analogues showed potent cytostatic activity against L1210 cell line, but cytotoxicity of the 4-N-alkylgemcitabine analogues was low. However, 4-N-alkanoyl and 4-N-alkyl analogues had comparable antiproliferative activities in the HEK293 cells. The 4-N-alkyl analogue with a terminal azide group was shown to be localized inside HEK293 cells by fluorescence microscopy after labelling with Fluor 488-alkyne. The [18F]4-N-alkyl or alkanoyl silane gemcitabine analogues were successfully synthesized using microscale and conventional silane-labeling radiochemical protocols. Preliminary positron-emission tomography (PET) imaging in mice showed the biodistribution of [18F]4-N-alkyl to have initial concentration in the liver, kidneys and GI tract followed by increasing signal in the bone. PMID- 29471121 TI - Diamine and PEGylated-diamine conjugates of triterpenic acids as potential anticancer agents. AB - A set of 18 amide derivatives of oleanolic or maslinic acid has been semi synthesised. Twelve were diamine conjugates at C-28 of these triterpenic acids and the other six were PEGylated-diamine derivatives. The cytotoxic effects of these 18 triterpenic derivatives in three cancer-cell lines (B16-F10, HT29, and Hep G2) have been assayed, and have been compared to three non-tumour cell lines of the same or a similar tissue (HPF, IEC-18, and WRL68). The cell viability percentages for the non-tumour HPF line for almost all diamine conjugates of the tested triterpenic acids ranged from 81% to 94%. The best cytotoxic results were achieved with the diamine conjugates of oleanolic or maslinic acid with the shortest and the longest diamine chain (IC50 values from 0.76 MUM to 1.76 MUM), on the B16-F10 cell line, being between 140- and 20-fold more effective than their corresponding precursors. Four diamine conjugates of these triterpenic acids showed apoptotic effects on treated cells of the B16-F10 line, with total apoptosis rates, relative to control, of between 73% and 90%. The DNA-histogram analysis revealed that all compounds tested produced cell-cycle arrest in B16-F10 cells, increasing the number of these cells in the S phase. All the compounds analysed, except one, did not cause changes in mitochondrial-membrane potential during apoptosis of the B16-F10 cancer cells, suggesting an activation of the extrinsic apoptotic pathway for these compounds. PMID- 29471122 TI - Conformational mimetics of the alpha-methyl chalcone TUB091 binding tubulin: Design, synthesis and antiproliferative activity. AB - Based on the conformation of the alpha-methyl chalcone TUB091 in its complex with tubulin, a series of conformational mimetics have been designed and synthesized where the methyl group of the chalcone has been fused to phenyl ring B resulting in 1,2,3,4-tetrahydronaphthalen-2-yl aryl ketones. Among the synthesized compounds, the 5-amino-6-methoxy derivative, with a similar substitution pattern to that of TUB091, showed antiproliferative activity around 20 nM against tumor and endothelial cells. Tubulin binding experiments confirmed its binding to tubulin at the colchicine site with a Kb of 2.4 * 106 M-1 resulting in the inhibition of the in vitro assembly of purified tubulin. Moreover, based on the recently reported complex of combretastatin A4 (CA4) with tubulin, a comparative analysis of the binding mode of CA4 and the alpha-methyl chalcone to tubulin has been performed. PMID- 29471123 TI - Gold(III) bis(thiosemicarbazonate) compounds in breast cancer cells: Cytotoxicity and thioredoxin reductase targeting. AB - Gold(III) compounds have received increasing attention in cancer research. Three gold complexes of general formula [AuIIIL]Cl, where L is benzil bis(thiosemicarbazonate), compound 1, benzil bis(4-methyl-3-thiosemicarbazonate), compound 2, or benzil bis(4-cyclohexyl-3-thiosemicarbazonate), compound 3, have been synthesized and fully characterized, including the X-ray crystal structure of compound 3, confirming square-planar geometry around the gold(III) centre. Compound 1 showed moderate cytotoxicity and accumulation in MCF7 breast cancer cells but did not inhibit thioredoxin reductase (TrxR) activity and did not induce reactive oxygen species (ROS) production. Compound 2, the least cytotoxic, was found to be capable of modestly inhibiting TrxR activity and produced low levels of ROS in the MCF7 cell line. The most cytotoxic compound, 3, had the highest cellular accumulation and its distribution pattern showed a clear preference for the cytosol and mitochondria of MCF7 cells. It readily hampered intracellular TrxR activity leading to a dramatic alteration of the cellular redox state and to the induction of cell death. PMID- 29471124 TI - Methods and procedures for: A randomized double-blind study investigating dose dependent longitudinal effects of vitamin D supplementation on bone health. AB - The optimum dose of vitamin D and corresponding serum 25-hydroxyvitamin D (25OHD) concentration for bone health is still debated and some health practitioners are recommending doses well above the Canada/USA recommended Dietary Reference Intake (DRI). We designed a three-year randomized double-blind clinical trial investigating whether there are dose-dependent effects of vitamin D supplementation above the Dietary Reference Intake (DRI) on bone health. The primary aims of this study are to assess, whether supplementation of vitamin D3 increases 1) volumetric bone mineral density measured by high-resolution peripheral quantitative computed tomography (HR-pQCT); 2) bone strength assessed by finite element analysis, and 3) areal bone mineral density by dual X-ray absorptiometry (DXA). Secondary aims are to understand whether vitamin D3 supplementation improves parameters of bone microarchitecture, balance, physical function and quality of life. Participants are men and women aged 55-70 years, with women at least 5-years post-menopause. The intervention is daily vitamin D3 supplementation doses of 400, 4000 or 10,000 IU. Participants not achieving adequate dietary calcium intake are provided with calcium supplementation, up to a maximum supplemental dose of 600 mg elemental calcium per day. Results from this three-year study will provide evidence whether daily vitamin D3 supplementation with adequate calcium intake can affect bone density, bone microarchitecture and bone strength in men and women. Furthermore, the safety of high dose daily vitamin D3 supplementation will be explored. PMID- 29471125 TI - Biochar activation with exoenzymes induced by earthworms: A novel functional strategy for soil quality promotion. AB - The activation of biochar (carbonaceous material generated by pyrolysis of biomass) with extracellular enzymes generated from soil biological processes was studied via a 2-month microcosm using earthworms. The isolation of biochar particles (post-incubated biochar) from earthworm-treated soils allowed to confirm an enrichment of biochar with extracellular enzymes associated to biogeochemical (alkaline phosphatase, beta-glucosidase and arylsulfatase) and bioremediation pathways (carboxylesterase). The hydrolytic activity of this biochar incubated with earthworms was up to 8 times higher compared with that of control biochar (incubated in earthworm-free soils). More interestingly, the enzyme carboxylesterase was stabilized onto biochar surface as demonstrated by its unchanged hydrolytic activity after multiple water rinses of the post incubated biochar, and the remaining activity following heat stress. Moreover, this biochar-bound carboxylesterase activity was sensitive to inhibition by organophosphorus (23-100% of control activity) and methyl carbamate pesticides (37-57%), demonstrating that bioactivated biochar with carboxylesterases may inactivate these agrochemicals by providing stable ligands of enzymatic nature. PMID- 29471126 TI - Adsorption mechanism of extracellular polymeric substances from two bacteria on Ultisol and Alfisol. AB - The primary objective of this study was to identify the capacity and mechanism of extracellular polymeric substance (EPS) adsorption on soil colloids of Alfisol and Ultisol at different pH and ionic strengths. Two kinds of EPS were extracted from Bacillus subtilis and Pseudomonas fluorescens by centrifugation, and their adsorption on Ultisol and Alfisol was investigated using a batch adsorption experiment and attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR). The average diameter of EPS from B. subtilis and P. fluorescens was 1825 and 1288 nm, respectively, and both the EPS were negatively charged. The zeta potentials of the two EPS became more negative with increasing solution pH from 3 to 8 and less negative with increasing ionic strength from 0 to 80 mM. The maximum adsorption capacity of EPS-C and EPS-N on Alfisol was higher than that on Ultisol, whereas the maximum adsorption capacity of EPS-P on Alfisol was lower than that on Ultisol. The adsorption of EPS-C, EPS-N, and EPS-P of both the EPS on Ultisol and Alfisol decreased with increasing solution pH from 3 to 8. Adsorption of EPS-C, EPS-N, and EPS-P of both the EPS on Alfisol significantly increased with increasing ionic strength from 0 to 10 mM, whereas it remained constant, slightly increased, or reduced, when the ionic strength was increased from 10 to 80 mM. The adsorption of EPS-C, EPS-N, and EPS-P on Ultisol slightly increased with increasing ionic strength from 0 to 80 mM. Saturation coverage determined by ATR-FTIR showed that adsorption of whole EPS on Ultisol was higher than that on Alfisol at pH 6 after 60 min. Thus, electrostatic force between EPS and soil colloids played an important role in EPS adsorption. Besides, proteins and phosphate groups in EPS also contributed to EPS adsorption on soil colloids. PMID- 29471128 TI - Spatiotemporal magnetic fields enhance cytosolic Ca2+ levels and induce actin polymerization via activation of voltage-gated sodium channels in skeletal muscle cells. AB - Cellular function is modulated by the electric membrane potential controlling intracellular physiology and signal propagation from a motor neuron to a muscle fiber resulting in muscle contraction. Unlike electric fields, magnetic fields are not attenuated by biological materials and penetrate deep into the tissue. We used complex spatiotemporal magnetic fields (17-70 mT) to control intracellular signaling in skeletal muscle cells. By changing different parameters of the alternating magnetic field (amplitude, inversion time, rotation frequency), we induced transient depolarization of cellular membranes leading to i) Na+ influx through voltage-gated sodium channels (VGSC), ii) cytosolic calcium increase, and iii) VGSC- and ryanodine receptor-dependent increase of actin polymerization. The ion fluxes occurred only, when the field was applied and returned to baseline after the field was turned off. The 30-s-activation-cycle could be repeated without any loss of signal intensity. By contrast, static magnetic fields of the same strength exhibited no effect on myotube Ca2+ levels. Mathematical modeling suggested a role for the alternating magnetic field-induced eddy current, which mediates a local change in the membrane potential triggering the activation of VGSC. These findings might pave the way for the use of complex magnetic fields to improve function of skeletal muscles in myopathies. PMID- 29471127 TI - Targeting CD14 on blood derived cells improves intracortical microelectrode performance. AB - Intracortical microelectrodes afford researchers an effective tool to precisely monitor neural spiking activity. Additionally, intracortical microelectrodes have the ability to return function to individuals with paralysis as part of a brain computer interface. Unfortunately, the neural signals recorded by these electrodes degrade over time. Many strategies which target the biological and/or materials mediating failure modes of this decline of function are currently under investigation. The goal of this study is to identify a precise cellular target for future intervention to sustain chronic intracortical microelectrode performance. Previous work from our lab has indicated that the Cluster of Differentiation 14/Toll-like receptor pathway (CD14/TLR) is a viable target to improve chronic laminar, silicon intracortical microelectrode recordings. Here, we use a mouse bone marrow chimera model to selectively knockout CD14, an innate immune receptor, from either brain resident microglia or blood-derived macrophages, in order to understand the most effective targets for future therapeutic options. Using single-unit recordings we demonstrate that inhibiting CD14 from the blood-derived macrophages improves recording quality over the 16 week long study. We conclude that targeting CD14 in blood-derived cells should be part of the strategy to improve the performance of intracortical microelectrodes, and that the daunting task of delivering therapeutics across the blood-brain barrier may not be needed to increase intracortical microelectrode performance. PMID- 29471129 TI - Issues in estimating probability of detection of NDT techniques - A model assisted approach. AB - In order to successfully implement Damage Tolerance (DT) methodology for aero engines, Non-Destructive Testing (NDT) techniques are vital for assessing the remaining life of the component. Probability of Detection (POD), a standard measure of NDT reliability, is usually estimated as per MIL-HDBK-1823A standard. Estimation of POD of any NDT technique can be obtained by both experimental and model assisted methods. POD depends on many factors such as material, geometry, defect characteristics, inspection technique, etc. These requirements put enormous limitations on generating experimental POD curves and hence, Model Assisted Probability of Detection (MAPOD) curves are currently in vogue. In this study, MAPOD approaches were demonstrated by addressing various issues related to selection of crack sizes distribution, challenges involved in censoring and regression, estimation of distribution parameters, etc. Ultrasonic testing on volumetric defects has been identified as a platform to discuss the challenges involved. A COMSOL Multiphysics based FEM numerical model developed to simulate ultrasonic response from a Ti-6Al-4V cylindrical block has been validated experimentally. Further, the individual ultrasonic response from various Flat Bottom Hole (FBH) defects following lognormal distribution has been generated using the numerical model. a90/95 (detecting a flaw with 90% probability and 95% confidence) value obtained from POD curve showed that the POD value increased with an increase in decision threshold. PMID- 29471130 TI - Effect of e-cigarette advertisement exposure on intention to use e-cigarettes in adolescents. AB - INTRODUCTION: With the growth of electronic cigarettes use, curiosity about and experimentation with these products has increased among adolescents. The purpose of the present study was to evaluate the moderating effect of e-cigarette advertisement (ad) exposure on the relation between perceptions of use and intentions to use in youth. METHODS: Multiple regression analyses utilizing data from the 2014 National Youth Tobacco Survey (N = 17,286) were used to evaluate the effect of ad exposure, perceived harmfulness, barriers, and benefits of e cigarette use on intentions to use among youth who had never used e-cigarettes. RESULTS: Models for non-smokers accounted for 15.5% of the variance in intention to use (R2 = 0.155, F (15) = 187.0, p < 0.001). Results demonstrate that an increase in the number of exposures to e-cigarette ads was associated with an increase in intent to use (b = 0.039, t = 7.4, p < 0.001). Models also demonstrated significant interactions between ad exposure and perceptions of use on future intention to use. For smokers, models explained 11.1% of the variance in intention to use (R2 = 0.111, F (15) = 3.1, p < 0.001). Ad exposure had a non significant effect on intention to use e-cigarettes (b = -0.010, t = -0.2, p = 0.859). In smokers, ad exposure did not significantly affect the association between perceptions of use and intention to use. CONCLUSIONS: Ads are most effective at attracting non-smoking youth as new users rather than promoting product switching in young cigarette smokers. PMID- 29471131 TI - Aerobic and strength training induce changes in oxidative stress parameters and elicit modifications of various cellular components in skeletal muscle of aged rats. AB - Skeletal muscle aging is associated with loss of mass, function, and strength-a condition known as sarcopenia. It has been reported that sarcopenia can be attenuated by physical exercise. Therefore, we investigated whether 2 different physical exercise protocols could modulate and induce changes in oxidative and inflammatory parameters, as well as in BDNF and DNA repair enzyme levels in skeletal muscle tissue of aged rats. Aging Wistar rats performed treadmill or strength training for 50 min 3 to 4 times a week for 8 weeks. Strength training decreased 2',7'-dichlorofluorescein (DCFH) oxidation (P = 0.0062); however, nitric oxide, protein deglycase DJ-1, and tumor necrosis factor alpha (TNF-alpha) levels increased after aerobic training (P = 0.04, P = 0.027 and P = 0.009, respectively). Both exercise protocols increased superoxide dismutase (SOD) and catalase (CAT) activity (P = 0.0017 and P = 0.0326) whereas the activity of glutathione (GSH) (P = 0.0001) was decreased. Brain-derived neurotropic factor (BDNF) levels were not affected by exercise, but 8-oxoguanine glycosylase (OGG1) decreased after strength training (P = 0.0007). In conclusion, oxidative parameters showed that skeletal muscle adapt to increased ROS levels, reducing the risk of free radical damage to the tissue after both exercise protocols. These results show that the effects of physical exercise on skeletal muscle are mediated in an exercise type-dependent manner. PMID- 29471132 TI - High-intensity body weight training is comparable to combined training in changes in muscle mass, physical performance, inflammatory markers and metabolic health in postmenopausal women at high risk for type 2 diabetes mellitus: A randomized controlled clinical trial. AB - OBJECTIVE: This study compared the effects of 12 weeks of high-intensity interval body weight training (HIBWT) with combined training (COMT; aerobic and resistance exercises on body composition, a 6-minute walk test (6MWT; physical performance), insulin resistance (IR) and inflammatory markers in postmenopausal women (PW) at high risk of type 2 diabetes mellitus (TDM2). METHODS: In this randomized controlled clinical study, 16 PW at high risk of TDM2 were randomly allocated into two groups: HIBWT (n = 8) and COMT (n = 8). The HIBWT group performed a training protocol (length time ~28 min) consisting of ten sets of 60 s of high intensity exercise interspersed by a recovery period of 60 s of low intensity exercise. The COMT group performed a training protocol (length time ~60 min) consisting of a 30 min walk of moderate intensity following by five resistance exercises. All training sessions were performed in the university gym facility three days a week (no consecutive days) for 12 weeks. All outcomes (body composition, muscle function, and IR and inflammatory markers) were assessed at the baseline and at the end of the study. RESULTS: Both groups increased (P < 0.05) muscle mass index (MMI), 6MWT, and interleukin 1 receptor antagonist and decreased fasting glucose, glycated hemoglobin, Insulin, HOMA-IR, and monocyte chemoattractant protein-1 (trend, P = 0.056). HIBWT effects were indistinguishable (P > 0.05) from the effects of COMT. There was a significant (P < 0.05) interaction of time by the group in muscle strength, indicating that only the COMT increased the muscle strength. CONCLUSIONS: This study suggests that changes in HOMA, IL-1ra, 6MWT, and MMI with HITBW are similar when compared to COMT in PW at high risk of TDM2. TRIAL REGISTRATION: The patients were part of a 12-week training study (ClinicalTrials.gov Identifier: NCT03200639).

AB - In this paper, a one-layer recurrent neural network is proposed for solving a class of nonsmooth, pseudoconvex optimization problems with general convex constraints. Based on the smoothing method, we construct a new regularization function, which does not depend on any information of the feasible region. Thanks to the special structure of the regularization function, we prove the global existence, uniqueness and "slow solution" character of the state of the proposed neural network. Moreover, the state solution of the proposed network is proved to be convergent to the feasible region in finite time and to the optimal solution set of the related optimization problem subsequently. In particular, the convergence of the state to an exact optimal solution is also considered in this paper. Numerical examples with simulation results are given to show the efficiency and good characteristics of the proposed network. In addition, some preliminary theoretical analysis and application of the proposed network for a wider class of dynamic portfolio optimization are included. PMID- 29471134 TI - Citrobacter freundii impairs the phosphoryl transfer network in the gills of Rhamdia quelen: Impairment of bioenergetics homeostasis. AB - The precise coupling of spatially separated intracellular adenosine triphosphate (ATP)-producing and ATP-consuming, catalyzed by creatine kinase (CK), adenylate kinase (AK), and pyruvate kinase (PK), is a critical process in the bioenergetics of tissues with high energy demand, such as the branchial tissue. The effects of Citrobacter freundii infection on gills remain poorly understood, limited only to histopathological studies. Thus, the aim of this study was to evaluate whether experimental infection by C. freundii impairs the enzymes of the phosphoryl transfer network in gills of silver catfish (Rhamdia quelen). The CK (cytosolic and mitochondrial) and AK activities decreased in infected compared to uninfected animals, while the PK activity did not differ between groups. The gill histopathology of infected animals revealed extensive degeneration with fusion and necrosis of secondary lamellae, detachment of superficial epithelium, aneurysm, vessel congestion and inflammatory process. Based on these evidences, the inhibition and absence of an efficient communication between CK compartments caused the impairment of the branchial bioenergetics homeostasis, which was not compensated by the augmentation on branchial AK activity in an attempt to restore energy homeostasis. In summary, these alterations contribute to disease pathogenesis linked to branchial tissue in animals infected with C. freundii. PMID- 29471135 TI - Murine model for the evaluation of candiduria caused by Candida tropicalis from biofilm. AB - To evaluate the pathophysiology of catheter-associated candiduria, the bladders of female mice were infected with Candida tropicalis. One group was implanted with a catheter fragment with preformed biofilm by cystotomy technique, while another group received, in separate, a sterile catheter fragment and a correspondent yeast suspension. The bladder tissues were examined by histopathology and the quantity of colony forming units was evaluated. All the animals presented inflammation and the presence of C. tropicalis was observed in the tissue within 72 h of the introduction of biofilm, while 75% of the mice remained infected after 144 h. However, only 50% of animals from the group infected with C. tropicalis in suspension (planktonic yeasts), exhibited such signs of infection over time. The cystotomy technique is therefore viable in mice, and is an effective model for evaluating the pathogenesis of candiduria from catheter biofilms. The model revealed the potential of C. tropicalis infectivity and demonstrated more effective evasion of the host response in biofilm form than the planktonic yeast.

AB - Mycotoxins are responsible for economic losses in the swine production industry, especially during post-weaning, when piglets are physiologically immature. Spray dried porcine plasma (SDPP), added to pig diets, may help reduce losses due to mycotoxins. This work investigates the effects of SDPP in post-weaning piglets fed with diets containing natural contaminants or with more contaminants (co contamination by mycotoxins). Fifty-six castrated weaned piglets were used in a randomized 2 (0 and 6% of SDPP) x 2 (natural contamination or co-contamination with mycotoxin) factorial design, with seven experimental units of two piglets each. The natural contaminants were 0.95 MUg/kg aflatoxins +450 MUg/kg fumonisins. The co-contaminated diet contained 300 MUg/kg aflatoxins +8000 MUg/kg fumonisins. Animals were fed 15 days with experimental diets. Feed intake, weight gain, feed efficiency, diarrhea incidence, and economic feasibility of SDPP treatement were evaluated in three periods of five days each. There was no interaction (P < 0.05) between mycotoxins levels and SDPP. Feed intake, weight gain and feed efficiency were higher (P < 0.05) in diets supplemented with SDPP. Animals fed with SDPP showed lower (P < 0.05) diarrhea incidence in the 1-10 day and 1-15 day periods. The experimental dose of mycotoxins reduced (P < 0.05) weight gain at 11-15 days. SDPP proved to be economical feasible over the total experimental period (1-15 days). Spray-dried plasma improved weight gain, feed intake and reduced diarrhea incidence in piglets post-weaning, but did not correlate with various levels of mycotoxins.

AB - Innumerable Escherichia coli of animal origin are identified, which are of economic significance, likewise, cattle, sheep and goats are the carrier of enterohaemorrhagic E. coli, which are less pathogenic, and can spread to people by way of direct contact and through the contamination of foodstuff or portable drinking water, causing serious illness. The immunization of ruminants has been carried out for ages and is largely acknowledged as the most economical and maintainable process of monitoring E. coli infection in ruminants. Yet, only a limited number of E. coli vaccines are obtainable. Mucosal surfaces are the most important ingress for E. coli and thus mucosal immune responses function as the primary means of fortification. Largely contemporary vaccination processes are done by parenteral administration and merely limited number of E. coli vaccines are inoculated via mucosal itinerary, due to its decreased efficacy. Nevertheless, aiming at maximal mucosal partitions to stimulate defensive immunity at both mucosal compartments and systemic site epitomises a prodigious task. Enormous determinations are involved in order to improve on novel mucosal E. coli vaccines candidate by choosing apposite antigens with potent immunogenicity, manipulating novel mucosal itineraries of inoculation and choosing immune-inducing adjuvants. The target of E. coli mucosal vaccines is to stimulate a comprehensive, effective and defensive immunity by specifically counteracting the antibodies at mucosal linings and by the stimulation of cellular immunity. Furthermore, effective E. coli mucosal vaccine would make vaccination measures stress-free and appropriate for large number of inoculation. On account of contemporary advancement in proteomics, metagenomics, metabolomics and transcriptomics research, a comprehensive appraisal of the immeasurable genes and proteins that were divulged by a bacterium is now in easy reach. Moreover, there exist marvellous prospects in this bourgeoning technologies in comprehending the host bacteria affiliation. Accordingly, the flourishing knowledge could massively guarantee to the progression of immunogenic vaccines against E. coli infections in both humans and animals. This review highlight and expounds on the current prominence of mucosal and systemic immunogenic vaccines for the prevention of E. coli infections in ruminants.

AB - This present study was conducted to evaluate the antimicrobial effects of tannic acid (TA) against isolated ruminal bacteria from adult sheep. Rumen samples were collected from two (2) adults sheep, and a total of nine (9) ruminal bacteria were isolated from the sample. The sensitivity of the ruminal bacteria isolates to 0.63, 1.25, 2.50, 5.00 and 10.00 mg TA/mL of growth medium was determined using clearance zone (CZ) of Kirby-Bauer disc diffusion susceptibility test. There was observable increase in the sensitivity of all bacterial isolates as the level of TA increases. Not all bacterial isolates have the capacity to tolerate more than 1.25 mg TA/mL. The result shows that only 20% of the bacterial isolates had the capacity to tolerate 0.63 and 1.25 mg of tannic acid per liter. This concentration of tannic acid would be equivalent to 2% tannin in the diet of ruminant. Our findings shows that increase in concentration of tannic acid completely inhibited the ruminal bacteria from the sheep rumen.

AB - Mycoplasma gallisepticum (M. gallisepticum) is one of the most important pathogens that cause chronic respiratory disease in chickens. M. gallisepticum derived lipid-associated membrane proteins (LAMPs) are thought to be one of the major factors in mycoplasma pathogenesis and are potent inducers of the host innate immune response. However, the interaction of pathogenic M. gallisepticum derived LAMPs with Toll-like receptors (TLRs) and the signaling pathways responsible for activating inflammation and NF-kappaB have not been fully elucidated. In this study, we found that IL-1beta expression was induced in DF-1 cells stimulated with M. gallisepticum LAMPs. Subcellular localization experiments using immunofluorescence assays (IFAs) showed p65 translocation from the cytoplasm to the nucleus in DF-1 cells following stimulation with M. gallisepticum LAMPs. Phosphorylation of p65 was detected in LAMP-stimulated DF-1 cells. Treatment with an NF-kappaB-specific inhibitor showed that NF-kappaB is required for M. gallisepticum LAMP-induced IL-1beta expression. In addition, the results indicated that TLR2 and myeloid differentiation primary-response protein 88 (MyD88)-dependent signaling pathways were involved in the activation of NF kappaB by M. gallisepticum LAMPs. Together, these results provide evidence that M. gallisepticum LAMPs activate IL-1beta production through the NF-kappaB pathway via TLR2 and MyD88. PMID- 29471141 TI - The morphological and molecular mechanisms of epithelial/endothelial-to mesenchymal transition and its involvement in atherosclerosis. AB - Cell transdifferentiation occurs during cardiovascular development or remodeling either as a pathologic feature in the progression of disease or as a response to injury. Endothelial-to-Mesenchymal Transition (EndMT) is a process that is classified as a specialized form of Epithelial-to-Mesenchymal Transition (EMT), in which epithelial cells lose their epithelial characteristics and gain a mesenchymal phenotype. During transdifferentiation, cells lose both cell-cell contacts and their attachment to the basement membrane. Subsequently, the shape of the cells changes from a cuboidal to an elongated shape. A rearrangement of actin filaments facilitates the cells to become motile and prime their migration into the underlying tissue. EMT is a key process during embryonic development, wound healing and tissue regeneration, but has also been implicated in pathophysiological processes, such organ fibrosis and tumor metastases. EndMT has been associated with additional pathophysiological processes in cardiovascular related diseases, including atherosclerosis. Recent studies prove a significant role for EndMT in the progression and destabilization of atherosclerotic plaques, as a consequence of EndMT-derived fibroblast infiltration and the increased secretion of matrix metalloproteinase respectively. In this review we will discuss the essential molecular and morphological mechanisms of EMT and EndMT, along with their common denominators and key differences. Finally, we will discuss the role of EMT/EndMT in developmental and pathophysiological processes, focusing on the potential role of EndMT in atherosclerosis in more depth. PMID- 29471140 TI - Activation of endothelial TrkB receptors induces relaxation of resistance arteries. AB - While brain-derived neurotrophic factor (BDNF) was previously reported to induce relaxation of conduit artery, whether the BDNF/TrkB (tropomyosin-related kinase) pathway is involved in the tone control of resistance arteries is not known. This study investigated TrkB receptors levels/localization and the vasomotor effect of the TrkB receptor agonist LM22A-4 in isolated third-order mesenteric arteries from rats. Immunostaining revealed the presence of both full-length and truncated TrkB receptors, especially at the endothelial level. By using wire myography, LM22A-4 induced vascular relaxation that was significantly decreased by cyclotraxin B as a non-competitive TrkB antagonist and fully prevented by endothelium removal. Inhibitors of NO, EDHF, PGI2 production and the PI3K/Akt pathways separately reduced LM22A-4 induced-relaxation. By contrast, inhibition of Raf/MEK, PLCgamma and CaM/CaMKII pathways did not change the relaxant effect of LM22A-4. Interestingly, BDNF also induced an endothelium and TrkB-dependent relaxation. These results indicate that endothelial TrkB activation results in the relaxation of resistance vessels via PI3K/Akt-induced eNOS phosphorylation and production of EDHF and PGI2. These data are consistent with the contribution of the endothelial BDNF/TrkB pathway to the regulation of peripheral vascular tone. They also validate the use of LM22A-4 as a reliable pharmacological agent for studying the vascular effect of BDNF. PMID- 29471142 TI - Hair analysis when external contamination is in question: A review of practical approach for the interpretation of results. AB - Despite having been extensively discussed over the last decade, the differentiation between systemic exposure and external contamination still continues to be one of the limitations of hair testing for drugs. For this reason, we consider it worthwhile to re-state some basic principles in this short review. Various studies investigating a diversity of wash protocols, most using artificially contaminated hair with cocaine, have been valuable in evaluating wash efficacy and in understanding the incorporation of drugs in hair. However, assessments of wash efficacy made with real hair samples, as opposed to artificially contaminated samples, provide a different perspective, and demonstrate how rarely external contamination affects the interpretation of results. Data from a large number of hair samples from crack cocaine users, confirmed the usefulness of our protocol to remove most of the externally deposited cocaine. The data showed that hair levels of cocaine and benzoylecgonine in crack cocaine users were overall high with ratio of benzoylecgonine to cocaine in all samples above 0.1. The wash residue concentrations of cocaine ranged from not detected to 21ng/mg with a median of 0.5ng/mg. Cocaine was detected in the wash residue in 105 out of 138 samples. The wash to hair cocaine ratio ranged from not detected to 0.36 with a median of 0.02. The wash to hair cocaine ratios were below 0.07 in 133 cases. The five cases that produced wash to hair ratios above 0.1, one sample was at 0.11, three at 0.13 and one at 0.36, possibly because these cases were at the lower end of cocaine levels, however, we could not rule out that the hair was contaminated. Whilst it is not possible to differentiate between the drug extracted from the hair and the drug attached to the outside of the hair, we can compare levels of drug in the wash residue with levels detected in the hair sample. In addition, further diagnostic criteria must be applied to minimise potential misdiagnosis of external contamination. When drugs are detected in hair, individuals have clearly been in an environment where drugs are present, but it is only on rare occasions that it is unclear whether this is the result of drug use or of external contamination, and, in those cases, the results of testing need to be interpreted in the light of corroborating evidence from clinical data or social context. PMID- 29471143 TI - Transdermal delivery of vitamin K using dissolving microneedles for the prevention of vitamin K deficiency bleeding. AB - Vitamin K deficiency within neonates can result in vitamin K deficiency bleeding. Ensuring that newborns receive vitamin K is particularly critical in places where access to health care and blood products and transfusions is limited. The World Health Organization recommends that newborns receive a 1 mg intramuscular injection of vitamin K at birth. Evidence from multiple surveillance studies shows that the introduction of vitamin K prophylaxis reduces the incidence of vitamin K deficiency bleeding. Despite these recommendations, coverage of vitamin K prophylactic treatment in low-resource settings is limited. An intramuscular injection is the most common method of vitamin K administration in neonates. In low- and middle-income countries, needle sharing may occur, which may result in the spread of bloodborne diseases. The objective of our study was to investigate the manufacture of microneedles for the delivery of vitamin K. Following microneedle fabrication, we performed insertion studies to assess the microneedle's mechanical properties. Results indicate that vitamin K in a microneedle array was successfully delivered in vitro across neonatal porcine skin with 1.80 +/- 0.08 mg delivered over 24 h. Therefore, this initial study shows that microneedles do have the potential to prevent vitamin K deficiency bleeding. Future work will assess delivery of vitamin K in microneedle array in vivo. PMID- 29471144 TI - Intestinal absorption and activation of decitabine amino acid ester prodrugs mediated by peptide transporter PEPT1 and enterocyte enzymes. AB - Decitabine (DAC), a potent DNA methyltransferase (DNMT) inhibitor, has a limited oral bioavailability. Its 5'-amino acid ester prodrugs could improve its oral delivery but the specific absorption mechanism is not yet fully understood. The aim of this present study was to investigate the in vivo absorption and activation mechanism of these prodrugs using in situ intestinal perfusion and pharmacokinetics studies in rats. Although PEPT1 transporter is pH dependent, there appeared to be no proton cotransport in the perfusion experiment with a preferable transport at pH 7.4 rather than pH 6.5. This suggested that the transport was mostly dependent on the dissociated state of the prodrugs and the proton gradient might play only a limited role. In pH 7.4 HEPES buffer, an increase in Peff was observed for L-val-DAC, D-val-DAC, L-phe-DAC and L-trp-DAC (2.89-fold, 1.2-fold, 2.73-fold, and 1.90-fold, respectively), compared with the parent drug. When co-perfusing the prodrug with Glysar, a known substrate of PEPT1, the permeabilities of the prodrugs were significantly inhibited compared with the control. To further investigate the absorption of the prodrugs, L-val DAC was selected and found to be concentration-dependent and saturable, suggesting a carrier-mediated process (intrinsic Km: 7.80 +/- 2.61 mM) along with passive transport. Determination of drug in intestinal homogenate after perfusion further confirmed that the metabolic activation mainly involved an intestinal first-pass effect. In a pharmacokinetic evaluation, the oral bioavailability of L val-DAC, L-phe-DAC and L-trp-DAC were nearly 1.74-fold, 1.69-fold and 1.49-fold greater than that of DAC. The differences in membrane permeability and oral bioavailability might be due to the different stability in the intestinal lumen and the distinct PEPT1 affinity which is mainly caused by the stereochemistry, hydrophobicity and steric hindrance of the side chains. In summary, the detailed investigation of the absorption mechanism by in vivo intestinal perfusion and pharmacokinetic studies showed that the prodrugs of DAC exhibited excellent permeability and oral bioavailability, which might be attributed to a hybrid (partly PEPT1-mediated and partly passive) transport mode and a rapid activation process in enterocytes. PMID- 29471145 TI - Establishment of an evaluation method to detect drug distribution in hair follicles. AB - Development of an appropriate method to evaluate drug disposition or targeting ability in hair follicles (HFs) is urgently needed in order to develop useful pharmaceutical products with pharmacological effects in HFs. In the present study, a cyanoacrylate biopsy (CB) method was used to measure drug disposition in HFs using a model hydrophilic drug, caffeine (CAF), and a lipophilic drug, 4 butylresorcinol (BR), in excised porcine skin. As a result, the height of HF replicas and the recovery ratio decreased with an increase in the application times of the CB method. HF replicas with a length of approximately 175 um were obtained using a single application of the CB method. Drug distribution in the HF was detected even 5 min after topical application regardless of the lipophilicity of the drugs, although no drug disposition was observed in the deeper layers of the stratum corneum at the same time (5 min). Furthermore, significantly higher amounts of BR were observed in the stratum corneum and HF, compared with those of CAF. These results suggested that the CB method could be useful to evaluate the safety and efficacy as well as the disposition of topically applied chemicals, especially for HF-targeting drugs. PMID- 29471146 TI - The impact of feedback valence and communication style on intrinsic motivation in middle childhood: Experimental evidence and generalization across individual differences. AB - Prior research among adolescents and emerging adults has provided evidence for the beneficial effects of positive (relative to negative) feedback and an autonomy-supportive (relative to a controlling) communication style on students' intrinsic motivation. Unfortunately, similar experimental research in middle childhood is lacking. Moreover, little attention has been paid to the question of whether individual differences in personality and perceived parenting play a role in these effects. In the current experimental study (N = 110; Mage = 10.71 years), children completed puzzles at school under one of four experimental conditions, thereby crossing normative feedback valence (i.e., positive vs. negative) with communication style (i.e., autonomy supportive vs. controlling). Prior to the experiment, children filled out questionnaires tapping into the Big Five personality traits and into perceived maternal autonomy support and psychological control. After the experimental induction, children rated several motivational constructs (i.e., intrinsic motivation and need-based experiences). In addition, their voluntary behavioral persistence in a subsequent challenging puzzle task was recorded objectively. Providing positive normative feedback in an autonomy-supportive way yielded the most favorable motivational outcomes. Both feedback valence and communication style yielded an independent impact on children's experiences of competence and autonomy during task engagement, which in turn helped to explain children's elevated intrinsic motivation, as reflected by their perceived interest and behavioral persistence. A few effects were moderated by children's perceived parenting and personality traits, but the number of interactions was limited. The discussion focuses on the motivating role of positive normative feedback and an autonomy-supportive communication style for children. PMID- 29471148 TI - Photonic technology for the treatments of venous and arterial ulcers: Case report. AB - In this report, we report a case study on a 50-year-old male patient with different chronic wounds, such as venous ulcer and arterial ulcer in both legs. These wounds have persisted for more than 10 years, despite the different treatments applied, including, different dressings, hyperbaric camera, as well as the used of several medicines of oral and topical application. The case is addressed with the aim to evaluate if treatment that uses combined techniques such as low level laser therapy (LLLT), photodynamic therapy and cellulose membrane is able to improve healing and reduction of time of treatment in those types of chronic wounds. The results show the clinical protocol is effective for the healing of arterial and venous ulcers and can be considered as a promising possibility. PMID- 29471147 TI - Blue light versus red light for photodynamic therapy of basal cell carcinoma in patients with Gorlin syndrome: A bilaterally controlled comparison study. AB - BACKGROUND: Photodynamic therapy (PDT) is a non-scarring alternative for treating basal cell carcinoma (BCC) in patients with Basal Cell Nevus Syndrome (BCNS), also known as Gorlin syndrome. In Europe, red light (635 nm) is the predominant source for PDT, whereas in the United States blue light (400 nm) is more widely available. The objective of this study was to conduct a head-to-head comparison of blue light and red light PDT in the same BCNS patients. METHODS: In a pilot study of three patients with 141 BCC lesions, 5-aminolevulinate (20% solution) was applied to all tumors. After 4 h, half of the tumors were illuminated with blue light and the remainder with red light. To ensure safety while treating this many tumors simultaneously, light doses were escalated gradually. Six treatments were administered in three biweekly sessions over 4 months, with a final evaluation at 6 months. Tumor status was documented with high-resolution photographs. Persistent lesions were biopsied at 6 months. RESULTS: Clearance rates after blue light (98%) were slightly better than after red light (93%), with blue light shown to be statistically non-inferior to red light. Eight suspicious lesions were biopsied, 5 after red light (5/5 were BCC) and 3 after blue light (1 was BCC). Blue light PDT was reportedly less painful. CONCLUSION: Blue light and red light PDT appear to be equally safe and perhaps equally effective for treating BCC tumors in BCNS patients. Further studies to evaluate long-term clearance after blue light PDT are needed. PMID- 29471149 TI - Is adjunctive photodynamic therapy more effective than scaling and root planing alone in the treatment of periodontal disease in hyperglycemic patients? A systematic review. AB - BACKGROUND: To assess the impact of scaling and root planing (SRP) with and without adjunct photodynamic therapy (PDT) in the treatment of periodontal disease (PD) in hyperglycemic patients. METHODS: Databases (MEDLINE, EMBASE; and CENTRAL) were searched up to December 2017. The addressed PICO question was: "What is the effectiveness of adjunctive PDT to non-surgical periodontal treatment by means of clinical periodontal and glycemic parameters in hyperglycemic patients?" RESULTS: Four clinical trials and 1 experimental study were included. Energy fluence, power output, power density and duration of irradiation were 2.79 J per square centimeters (J cm-2), 150 milliwatts (mW), 428 milliwatts per square centimeters (mW/cm2) and 133 s (s) respectively. All studies reporting clinical periodontal and metabolic parameters, showed that aPDT was effective in the treatment of periodontal inflammation in hyperglycemic patients at follow-up. When compared with SRP alone, none of the studies showed additional benefits of PDT as compared to SRP alone at follow up. Three studies showed no influence of SRP with or without aPDT on HbA1c levels. One study showed a significant reduction of HbA1c levels in adjunctive aPDT as compared to SRP alone at follow-up. CONCLUSION: It remains debatable whether adjunctive PDT as compared to SRP is effective in the treatment of periodontal inflammation and reduction of HbA1c levels in hyperglycemic patients. PMID- 29471150 TI - Comprehensive virome analysis reveals the complexity and diversity of the viral spectrum in pediatric patients diagnosed with severe and mild hand-foot-and-mouth disease. AB - The management of hand-foot-and-mouth disease(HFMD) epidemic is difficult due to the frequent emergence of non-EV71 and non-CVA16 enteroviruses and some cases testing negative for HFMD-associated causative agents. To clarify the virus spectrum of mild and severe HFMD, a comprehensive virome analysis of 238 samples was performed using next-generation sequencing (NGS). The data revealed total thirteen mammalian- and plant- virus families and diverse viral populations including enteroviruses, common respiratory viruses, diarrhea-related viruses, plant viruses and anelloviruses. A total of 18 viruses from 7 virus families were identified in severe cases, versus 37 viruses from 12 virus families in mild cases. Moreover, complicated mixed-infections of enteroviruses with common respiratory viruses were mainly found in severe cases(P = 0.013), while diarrhea related viruses were mainly found in mild cases(P < 0.001). This study provides the preliminary understanding of viromes both in mild and severe cases, which may benefit the detection of etiologic agents and prevention of HFMD. PMID- 29471151 TI - The herbicide atrazine affects sperm quality and the expression of antioxidant and spermatogenesis genes in zebrafish testes. AB - The herbicide atrazine (ATZ) is used worldwide in the control of annual grasses and broad-leaved weeds. The present study evaluated sperm quality parameters in zebrafish Danio rerio after 11-day exposure to nominal ATZ concentrations of 2, 10, and 100 MUg L-1. All ATZ concentrations caused a decrease in motility, mitochondrial functionality, and membrane integrity, as measured using conventional microscopy or fluorescence microscopy with specific probes. The DNA integrity of sperm was not affected. The levels of expression of genes related to spermatogenesis, antioxidant defenses, and DNA repair were also investigated using RT-qPCR. The ATZ caused transcriptional repression of the spermatogenesis related genes SRD5A2 and CFTR, the antioxidant defense genes SOD2 and GPX4B, and the DNA repair gene XPC. This is the first study to show that environmentally relevant concentrations of ATZ significantly affect the sperm quality in fish, possibly resulting in reduced fertility rates. In addition, we showed that the repression of genes related to spermatogenesis and cellular defense could be part of the mechanisms involved in the ATZ toxicity in the testes of male fish. PMID- 29471152 TI - Carpal tunnel release with a new mini-incision approach versus a conventional approach, a retrospective cohort study. AB - PURPOSE: We have make use of a new method to perform carpal tunnel release (CTR) through a 1.5-2.0 cm long incision The aim of this study is to introduce this method and to compare the effectiveness and safety of this approach to the conventional one. METHODS: We included consecutive patients diagnosed with primary carpal tunnel syndrome (CTS) who had CTR from January 2015 to September 2016. A total of 85 patients were included in our study. Among them, 42 patients with mini-incision approach were enrolled in group A, and the other 43 patients with conventional approach were enrolled in group B. Objective tests and subjective evaluations were performed to compare the outcomes of mini-incision approach with the conventional approach. Postoperative complications after the two approaches were also compared. RESULTS: At the 12-months follow-up, all patients in both groups got recovery. We found no significant differences between the two groups in postoperative pinch strength, grip strength, 2-point discrimination (2-PD), visual analogue scale (VAS) score, Levine score and the Disabilities of the Arm, Shoulder and Hand (DASH) score (P > 0.05). However, at the one-month follow-up, the percentage of patients with wound pain in group A was significantly lower than that in group B (0.05% vs. 0.23%, P = 0.03). At the 12 months follow-up, the number of patients with persistent wound pain and pillar pain in group B were 2 (4.7%) and 3 (7.0%) respectively, while no patients showed wound pain and pillar pain in group A. CONCLUSION: Patients with mini-incision approach have satisfactory surgical outcomes, low postoperative complications, and good appearance. PMID- 29471153 TI - The prevalence and clinical significance of postgastrectomy anemia in patients with early-stage gastric cancer: A retrospective cohort study. AB - BACKGROUND: This study explored the cumulative incidence of anemia after gastrectomy in patients with early-stage gastric cancer and evaluated the relationship between postgastrectomy anemia and nutritional factors during long term follow-up. METHODS: The medical records of patients with stage I gastric cancer who underwent curative gastrectomy between January 2006 and December 2013 were reviewed retrospectively. Hematologic parameters like hemoglobin, iron, ferritin, and vitamin B12 level were obtained prior to and after surgery with other nutritional parameters such as total protein, albumin, total cholesterol, triglyceride, calcium, and phosphate. Postoperative follow-up was conducted at 6 months after surgery and then annually for 5 years. RESULTS: Among 566 patients who did not have anemia preoperatively, 240 (42.4%) experienced anemia at least once during the 5 years after gastrectomy. These 240 patients (the anemia group) showed lower preoperative levels of hemoglobin, iron, ferritin, and triglyceride than those of the patients who did not experience anemia (the normal group). Total gastrectomy, advanced T stage, and lymph node metastasis were significantly more common in the anemia group compared with the normal group. During long-term follow-up, the anemia group showed significantly lower serum levels of nutritional markers, especially triglycerides, compared with the normal group. The overall survival rate was significantly lower in the anemia group than in the normal group. CONCLUSIONS: Anemia was common among gastric cancer patients after gastrectomy. Total gastrectomy and advanced T stage were identified as independent risk factors for postgastrectomy anemia. In addition, anemia might be associated with nutritional problems and a poor prognosis. Thus, regular monitoring and appropriate management of postgastrectomy anemia are important for early-stage gastric cancer patients with a long life expectancy. PMID- 29471154 TI - Tibial component sizing and alignment of TKR components does not significantly affect patient reported outcome measures at six months. A case series of 474 participants. AB - OBJECTIVES: Total knee replacement (TKR) is an effective means of alleviating the symptoms of end stage osteoarthritis. However, 20% of patients report dissatisfaction one year post-operatively. Previous literature has demonstrated contradictory evidence regarding the relationship between alignment and tibial component sizing with patient reported outcome measures (PROMs). We aim to investigate the association between alignment of TKR components and effect of tibial component sizing on PROMs. METHOD: A prospective, multicentre case series was performed at six centres. Baseline characteristics were collected at recruitment. Coronal and sagittal plain films were taken day one post operatively. Trained medical professionals blinded to outcome measured the alignment and degree of over/underhang of the tibial component in the coronal and sagittal place, with Oxford Knee Score (OKS) measured six months post operatively. RESULTS: 474 patients were recruited. Malaligned TKRs caused no significant difference in mean OKS change at six months (independent t-test) (p > 0.05). A multivariate regression model taking into account age, gender, body mass index and baseline OKS also demonstrated no significant difference (p > 0.05). With regards to tibial component sizing, 125 (27%) of patients had appropriately sized tibial components, 120 (26%) had overhang and 219 (53%) had underhang with no significant difference in OKS between the groups (p > 0.05). CONCLUSION: Tibial component sizing and alignment does not significantly affect short-term function, as measured by OKS, after total knee replacement. Dissatisfaction after TKR is likely due to other factors other than alignment of implant. PMID- 29471155 TI - Early results of magnetic sphincter augmentation versus fundoplication for gastroesophageal reflux disease: Systematic review and meta-analysis. AB - BACKGROUND: Laparoscopic Nissen and Toupet fundoplication (LF) are currently considered gold-standard surgical treatment for Gastroesophageal Reflux Disease (GERD). Magnetic Sphincter Augmentation (MSA) is an innovative surgical procedure that has been showed to be effective to control GERD symptoms and to reduce esophageal acid exposure. The aim of this systematic review and meta-analysis was to compare early outcomes of LF and MSA. MATERIALS AND METHODS: PubMed, MEDLINE, Embase, and Cochrane databases were consulted matching the terms "Gastroesophageal reflux or heartburn", "LINX or magnetic sphincter augmentation" and "fundoplication". Pooled effect measures were calculated using an inverse variance weighted or Mantel-Haenszel in random effects meta-analysis. Heterogeneity was evaluated using I2-index and Cochrane Q-test. Meta-regression was used to address the effect of potential confounders. RESULTS: Seven observational cohort studies, published between 2014 and 2017, matched the inclusion criteria. Overall, 1211 patients, 686 MSA and 525 LF, were included. Postoperative morbidity ranged from 0 to 3% in the MSA group and from 0 to 7% in the LF group, and there was no mortality. Dysphagia requiring endoscopic dilatation occurred in 9.3% and 6.6% of patients respectively (OR = 1.56, 95% CI = 0.61-3.95, p = 0.119). The pooled OR of gas/bloat symptoms, ability to vomit, and ability to belch were 0.39 (95% CI 0.25-0.61; p < 0.001), 10.10 (95% CI 5.33 19.15; p < 0.001), and 5.53 (95% CI 3.73-8.19; p < 0.001), respectively. The postoperative GERD-HRQL was similar (p = 0.101). The pooled OR of PPI suspension, endoscopic dilation, and reoperation were similar in the two patients groups (p = 0.548, p = 0.119, p = 0.183, respectively). CONCLUSION: Both anti-reflux procedures are safe and effective up to 1-year follow-up. PPI suspension rate, dysphagia requiring endoscopic dilatation, and disease-related quality of life are similar in the two patient groups. MSA is associated with less gas/bloat symptoms and increased ability to vomit and belch. PMID- 29471156 TI - Sliding hip screw versus cannulated cancellous screws for fixation of femoral neck fracture in adults: A systematic review. AB - OBJECTIVE: Femoral neck fracture is considered a difficult fracture to treat and often gives rise to unsatisfactory treatment results. Cannulated cancellous screws (CCS) or a sliding hip screw (SHS) are the mainstream internal fixations used for osteosynthesis of femoral neck fractures. There is a need to integrate existing data through a meta-analysis to investigate the safety and effectiveness of CCS and SHS in the treatment of femoral neck fractures. METHOD: According to the Cochrane Handbook for Systematic Reviews of Interventions, we screened for the relevant studies by searching Google Scholar, the Cochrane Controlled Trials Register, the Cochrane Library, Web of Science, EMBASE, and PubMed. The PICOS criteria was used to make sure the included studies fulfilled the inclusion criteria. RESULTS: Pooled data showed that there were no significant differences between the SHS and CCS groups for the Harris Hip Score. Significant differences were found between the SHS and CCS groups in terms of union time, postoperative complications, blood loss, operation time, incision length and length of hospital stay. CONCLUSIONS: Although the SHS and CCS groups showed similar functional recovery in treatment of femoral neck fracture in terms of the Harris Hip Score, the SHS group showed fewer postoperative complications and faster union time for patients with femoral neck fractures. Therefore, compared with CCS, the use of SHS may be a more effective treatment of femoral neck fractures.

AB - OBJECTIVE: This meta-analysis aimed to evaluate the safety and efficacy of aminocaproic acid in total knee arthroplasty (TKA) and total hip arthroplasty (THA). METHODS: The electronic databases include PubMed, Medline, Embase, Web of Science and the Cochrane Library from inception to January, 2018. Two reviewers abstracted total blood loss, hemoglobin drop, transfusion requirements, and postoperative complications. Data were using fixed-effects or random-effects models with weighted mean differences and risk difference for continuous and dichotomous variables, respectively. STATA 14.0 was used to perform the meta analysis. RESULTS: Six studies encompassing 756 participants were retrieved for this meta-analysis. Our study indicated that intravenous aminocaproic acid was associated with a significantly reduction in total blood loss, hemoglobin drop and need for transfusion. Additionally, no increased risk of thromboembolic events were identified. CONCLUSION: Based on the present meta-analysis, intravenous aminocaproic acid is effective and safe in total knee and hip arthroplasty without increasing the incidence of thromboembolic events. Further studies should focus on the comparison of aminocaproic acid and TXA in arthroplasties. PMID- 29471158 TI - Road traffic injuries: Cross-sectional cluster randomized countrywide population data from 4 low-income countries. AB - INTRODUCTION: Road traffic injuries (RTI) are a leading cause of morbidity and mortality around the world. The burden is highest in low and middle-income countries (LMICs) and is increasing. We aimed to describe the epidemiology of RTIs in 4 low-income countries using nationally representative survey data. METHODS: The Surgeons Overseas Assessment of Surgical Needs (SOSAS) survey tool was administered in four countries: Sierra Leone, Rwanda, Nepal and Uganda. We performed nationally representative cross-sectional, cluster randomized surveys in each country. Information regarding demographics, injury characteristics, anatomic location of injury, healthcare seeking behavior, and disability from injury was collected. Data were reported with descriptive statistics and evaluated for differences between the four countries using statistical tests where appropriate. RESULTS: A total of 13,765 respondents from 7115 households in the four countries were surveyed. RTIs occurred in 2.2% (2.0-2.5%) of the population and accounted for 12.9% (11.5-14.2%) of all injuries incurred. The mean age was 34 years (standard deviation +/-1years); 74% were male. Motorcycle crashes accounted for 44.7% of all RTIs. The body regions most affected included head/face/neck (36.5%) followed by extremity fractures (32.2%). Healthcare was sought by 78% road injured; 14.8% underwent a major procedure (requiring anesthesia). Major disability resulting in limitations of work or daily activity occurred in 38.5% (33.0-43.9%). CONCLUSION: RTIs account for a significant proportion of disability from injury. Younger men are most affected, raising concerns for potential detrimental consequences to local economies. Prevention initiatives are urgently needed to stem this growing burden of disease; additionally, improved access to timely emergency, trauma and surgical care may help alleviate the burden due to RTI in LMICs. PMID- 29471159 TI - Operation versus watchful waiting in asymptomatic or minimally symptomatic inguinal hernias: The meta-analysis results of randomized controlled trials. AB - INTRODUCTION: The aim of this article was to compare and analyze the outcomes of surgical repair and watchful waiting (WW) in the treatment of asymptomatic or minimally symptomatic inguinal hernias. METHODS: A systematic literature review was undertaken to identify studies that compare surgical repair and watchful waiting in asymptomatic or minimally symptomatic inguinal hernias. And all related data matching our standards were abstracted for Meta-analysis with RevMan 5.0.1. RESULTS: Less pain was observed in Operation group. However, there were no significant differences in Physical Component Score (PCS), mortality, surgical complications and postoperative hernia recurrence between WW group and Operation group. But a great number of patients would develop significant hernia-related symptoms and cross over to surgery over time in WW group. CONCLUSIONS: Patients have relative less pain in operation group compared with WW group. Although WW is safe in patients with asymptomatic or minimally symptomatic inguinal hernias, however, this strategy would merely delay rather than avoid surgical repair of hernias in the majority of inguinal hernia patients. PMID- 29471160 TI - Persistent first intersegmental artery (PFIA) visualized by three-dimensional computed tomography angiography in Chinese population. AB - BACKGROUND: Persistent first intersegmental artery (PFIA) is one of the most frequently vertebral artery (VA) variations. The presence of PFIA obviously increases the complexity and difficulty of vertebral lesion treatment. Thus, preoperative detection of PFIA is necessary to increase the successful rate of surgeries. We attempted to evaluate the utility value of three-dimension (3D) computed tomography angiography (CTA) for detecting PFIA in the north Chinese population. MATERIALS AND METHODS: Consecutive patients subjected to CTA between June 2012 and March 2014 were recruited from 5 clinical centers in the north of China. . The VA-cervical atlas complexus were observed by CTA. The assessment of PFIA was performed by reconstructing the images via Materialise's interactive medical image control system (MIMICS) and the measurement of VA diameter was performed on the source images. PFIA including unilateral and bilateral was calculated. The dominant side was defined as the unilateral VA with 130% fold larger diameter than the other side. RESULTS: A total of 200 north Chinese patients with mean age of 57.8 +/- 9.3 years old were enrolled in the present study. Total 400 VA-cervical atlas complexus were observed by 3D-CTA, among which 9 complexus (2.25%) were diagnosed with PFIA, and 3 complexus (0.75%) were presented with the dominant VA. The spinal surgical procedures were performed successfully in all the patients with no injury and complications to the VA. CONCLUSIONS: The incidence of PFIA in 400 VA-cervical atlas complexus are relatively high (2.25%) in our patient population. On the basis of relatively high prevalence of this anomaly, the preoperative detection of PFIA by 3D-CTA is recommended for the north Chinese population. PMID- 29471161 TI - Peripheral artery disease and antiplatelet treatment. AB - Peripheral artery disease (PAD) is one of the most important causes of cardiovascular morbidity and mortality and its prevalence is alarmingly increasing in modern societies. PAD shares common characteristics with the other atherosclerotic diseases but involves specifically the arteries of the lower extremities. Apart from the changes in lifestyle, antiplatelet agents are the hallmark of the treatment and improve the symptoms as well as the progression of the disease. Aspirin is the cornerstone of treatment and is administrated in doses ranging from 75 to 325mg daily. Additionally, cilostazol and clopidogrel have an important therapeutic role too. Novel antiplatelet agents are the subject of research in both experimental and clinical studies in order to evaluate the efficacy and safety profile. The most important antiplatelet factors which are under investigation are the novel P2Y12 receptor inhibitors prasugrel and ticagrelor. Furthermore, vorapaxar, a protease-activated receptor inhibitor, exhibits antiplatelet properties and has been studied in PAD.

AB - Arsenic remediation is often initiated by oxidizing As(III) to As(V) to alleviate its toxicity and mobility. Due to the easy availability, zero-valent Al (ZVAl) like Al can was considered as potential alternatives to facilitate As(III) oxidation. This study determined the capability and recycling of polyoxometalate (POM) to catalyze As(III) oxidation in Fe(II)-amended ZVAl systems. POM acquired electrons from ZVAl more effectively at pH 1 than at pH 2. While 76% of the reduced POM [POM(e-)] reacted with O2(g) to generate H2O2 at pH 1, only 60% of POM(e-) was used to produce H2O2 at pH 2. The remaining POM(e-) was oxidized by the generated H2O2. Such additional consumption of POM(e-) and H2O2 led to the incomplete As(III) oxidation in the system without residual ZVAl and emphasized the need for a continuous electron supply from ZVAl to compensate the depletion of POM(e-). After the hydrolyzation at pH 6.0, the XANES data evidenced that not only As(V) but WO4 released from the POM retained on surfaces of Al/Fe hydroxides. The competition for sorption sites on Al/Fe hydroxides between As(V) and WO4 led to the incomplete As removal. Despite the loss of WO4, the POM re polymerized at pH 1 still showed the comparable capability to catalyze As(III) oxidation with original POM. This study revealed electron transfer pathways from ZVAl to As(III) as catalyzed by POM and evidenced the effective POM recycling after As removal, which lowers the cost of POM application and turns the ZVAl/Fe(II)/POM/O2 system into a practical strategy for As remediation. PMID- 29471164 TI - Nanoparticles of volcanic ash as a carrier for toxic elements on the global scale. AB - At present, there is concern about engineered nanoparticles in the environment, whereas natural nanoparticles (NPs) and their impact are often neglected. In our paper, we demonstrate the important role of nanoparticles of volcanic ash in transport of toxic elements on a global scale. A single volcanic eruption can eject millions of tons of ash. NPs of volcanic ash reach the upper troposphere and the stratosphere and may "travel" around the world for years affecting human health, environment, and even climate. So far, there is a gap in exposure assessment of volcanic ash NPs since their chemical composition remains largely unknown. Here we show for the first time that volcanic ash NPs can serve as an important carrier for potentially toxic elements. The concentrations of Ni, Zn, Cd, Ag, Sn, Se, Te, Hg, Tl, Pb, Bi in volcanic ash NPs (<100 nm) were found to be 10-500 times higher than total contents of these elements in bulk samples. This is valid for volcanoes from different regions of the world (Kamchatka, Far East of Russia and Andes, Chile). The work opens a new door into studies on biogeochemical impact of volcanic ash. PMID- 29471162 TI - Hydrogen peroxide production by lactobacilli promotes epithelial restitution during colitis. AB - Inflammatory bowel disease (IBD) is a multifactorial chronic inflammatory disease of the gastrointestinal tract, characterized by cycles of acute flares, recovery and remission phases. Treatments for accelerating tissue restitution and prolonging remission are scarce, but altering the microbiota composition to promote intestinal homeostasis is considered a safe, economic and promising approach. Although probiotic bacteria have not yet fulfilled fully their promise in clinical trials, understanding the mechanism of how they exert beneficial effects will permit devising improved therapeutic strategies. Here we probe if one of the defining features of lactobacilli, the ability to generate nanomolar H2O2, contributes to their beneficial role in colitis. H2O2 generation by wild type L. johnsonii was modified by either deleting or overexpressing the enzymatic H2O2 source(s) followed by orally administering the bacteria before and during DSS colitis. Boosting luminal H2O2 concentrations within a physiological range accelerated recovery from colitis, while significantly exceeding this H2O2 level triggered bacteraemia. This study supports a role for increasing H2O2 within the physiological range at the epithelial barrier, independently of the enzymatic source and/or delivery mechanism, for inducing recovery and remission in IBD. PMID- 29471165 TI - Emission characteristics of PCDD/Fs in stack gas from municipal solid waste incineration plants in Northern China. AB - Emission characteristics including congener's profile, gas emissions and toxic equivalent concentration (TEQ) indicators of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in 57 stack gas samples from 6 municipal solid waste incinerators (MSWIs) in Northern China were investigated by gas chromatography high resolution mass spectrometry (HRGC-HRMS). Additionally, PCDD/Fs formation mechanisms from the MSWIs were briefly discussed. Results revealed that the concentrations and equivalent concentrations of PCDD/Fs emissions in stack gas from 6 MSWIs were in the range of 0.11-2.53 ng Nm-3 and 0.007-0.059 ng TEQ Nm-3, respectively. The emission factors of PCDD/Fs from 6 MSWIs varied from 0.027 to 0.225 MUg I-TEQ tonne-1, with a mean value of 0.17 MUg I-TEQ tonne-1 waste, which was estimated to an annual emission of 234.96 mg I-TEQ of PCDD/Fs from 6 MSWIs to the atmosphere. O8CDD, O8CDF and 1,2,3,4,6,7,8-H7CDD were the indicatory compounds of PCDD/Fs to apportion the sources of PCDD/Fs in environmental medium especially in ambient environment of MSWIs. 1,2,3,7,8,9-H6CDF and 1,2,3,4,7,8 H6CDF can be used as TEQ indicators for monitoring PCDD/Fs emission. Based on the positive matrix factorization (PMF) model, eight factors were extracted by the PMF analysis. Formation of low-chlorinated PCDDs (1,2,3,7,8-P5CDD, 1,2,3,4,7,8 H6CDD, 1,2,3,6,7,8-H6CDD and 1,2,3,7,8,9-H6CDD) possessed strong correlation, and the chlorophenols maybe the important precursors of low-chlorinated PCDDs, which were generated within the low chlorinated content. Penta- and hexa-PCDFs formation in stack gas from MSWI may block catalytic sites for PCDFs formation from carbon. Meanwhile, possible formation mechanisms of high-chlorinated PCDDs (hepta- and octa-PCDDs) and high-chlorinated PCDFs (hepta- and octa-PCDFs) were respectively dependent. PMID- 29471166 TI - Neurobehavioral effects of two metabolites of BDE-47 (6-OH-BDE-47 and 6-MeO-BDE 47) on zebrafish larvae. AB - Two metabolites, OH-BDEs and MeO-BDEs, of polybrominated diphenyl ethers (PBDEs) were ubiquitously detected in animal tissues and environmental samples, drawing a widely public concern to their toxicity. The comparison of toxicity between PBDEs and their metabolites has been a focus in recent years, however, comparisons seldom involve neurobehavioral toxicity of PBDEs metabolites in published works. In this study, zebrafish larvae were exposed to 6-OH-BDE-47 and 6-MeO-BDE-47 and their neurobehavioral traits (including locomotion, path angle, and social activity) were recorded using the instrument Zebrabox; meanwhile, light illumination was used as stimuli in the test duration. The results showed larvae were more active in dark periods than light periods, and preferred turning right (+) to left (-). Effects of the two metabolites varied in different behavioral indicators. They induced different effects on path angle but did not reverse the left-right asymmetry. 6-OH-BDE-47 did not induce the effects on larval locomotion and social activity, but mainly decreased average and routine turn numbers; 6-MeO BDE-47 promoted larvae responsive turns but inhibited social activity. This study offered new experimental means to the neurobehavioral toxicity of various PBDE metabolites. Further studies may focus on the toxic mechanisms of specific neurobehavioral traits. PMID- 29471167 TI - Adsorption of pharmaceuticals onto isolated polyamide active layer of NF/RO membranes. AB - Adsorption of trace organic compounds (TrOCs) onto the membrane materials has a great impact on their rejection by nanofiltration (NF) and reverse osmosis (RO) membranes. This study aimed to investigate the difference in adsorption of various pharmaceuticals (PhACs) onto different NF/RO membranes and to demonstrate the necessity of isolating the polyamide (PA) active layer from the polysulfone (PS) support layer for adsorption characterization and quantification. Both the isolated PA layers and the PA+PS layers of NF90 and ESPA1 membranes were used to conduct static adsorption tests. Results showed that apparent differences existed between the PA layer and the PA+PS layer in the adsorption capacity of PhACs as well as the time necessary to reach the adsorption equilibrium. PhACs with different physicochemical properties could be adsorbed to different extents by the isolated PA layer, which was mainly attributed to electrostatic attraction/repulsion and hydrophobic interactions. The PA layer of ESPA1 exhibited apparently higher adsorption capacities for the positively charged PhACs and similar adsorption capacities for the neutral PhACs although it had significantly less total interfacial area (per unit membrane surface area) for adsorption compared to the PA layer of NF90. The higher affinity of the PA layer of ESPA1 for the PhACs could be due to its higher capacity of forming hydrogen bonds with PhACs resulted from the modified chemistry with more -OH groups. This study provides a novel approach to determining the TrOC adsorption onto the active layer of membranes for the ease of investigating adsorption mechanisms. PMID- 29471168 TI - Developmental toxicity of penconazole in Zebrfish (Danio rerio) embryos. AB - Penconazole is a widely used fungicide that is toxic to a variety of organisms including fish. In the present study, we investigated the developmental toxicity of penconazole on zebrafish embryos by exposing to different concentrations of penconazole (0.8, 1.6 and 2.4 mg/L) from 4-h post-fertilization (hpf). Hatching, survival, and heart rates, body length, malformation and expression of several genes were detected. The results showed that penconazole exposure induced developmental toxicity, including delayed hatching, reduced survival, and heart rate. In addition to this, exposure to penconazole caused malformations, including pericardial edema, yolk sac edema, axial malformation, tail malformation and spinal curvature. Furthermore, RT-PCR results showed that mRNA levels of antioxidant genes were down-regulated after penconazole exposure. On the other hand, mRNA levels of interleukin 1 beta and interferon in embryos were up-regulated after exposure to penconazole. In summary, our data indicated that penconazole cause embryonic development toxicity on zebrafish embryos. PMID- 29471169 TI - PEGylated dendritic polyglycerol conjugate targeting NCAM-expressing neuroblastoma: Limitations and challenges. AB - Neural cell adhesion molecule (NCAM) is found to be a stem-cell marker in several tumor types and its overexpression is known to correlate with increased metastatic capacity. To combine extravasation- and ligand-dependent targeting to NCAM overexpressing-cells in the tumor microenvironment, we developed a PEGylated NCAM-targeted dendritic polyglycerol (PG) conjugate. Here, we describe the synthesis, physico-chemical characterization and biological evaluation of a PG conjugate bearing the mitotic inhibitor paclitaxel (PTX) and an NCAM-targeting peptide (NTP). PG-NTP-PTX-PEG was evaluated for its ability to inhibit neuroblastoma progression in vitro and in vivo as compared to non-targeted derivatives and free drug. NCAM-targeted conjugate inhibited the migration of proliferating endothelial cells, suggesting it would be able to inhibit tumor angiogenesis. The targeting conjugate provided an improved binding and uptake on IMR-32 cells compared to non-targeted control. However, these results did not translate to our in vivo model on orthotopic neuroblastoma bearing mice.

PMID- 29471171 TI - Triggering the activation of Activin A type II receptor in human adipose stem cells towards tenogenic commitment using mechanomagnetic stimulation. AB - Stem cell therapies hold potential to stimulate tendon regeneration and homeostasis, which is maintained in response to the native mechanical environment. Activins are members of the mechano-responsive TGF-beta superfamily that participates in the regulation of several downstream biological processes. Mechanosensitive membrane receptors such as activin can be activated in different types of stem cells via magnetic nanoparticles (MNPs) through remote magnetic actuation resulting in cell differentiation. In this work, we target the Activin receptor type IIA (ActRIIA) in human adipose stem cells (hASCs), using anti ActRIIA functionalized MNPs, externally activated through a oscillating magnetic bioreactor. Upon activation, the phosphorylation of Smad2/3 is induced allowing translocation of the complex to the nucleus, regulating tenogenic transcriptional responses. Our study demonstrates the potential remote activation of MNPs tagged hASCs to trigger the Activin receptor leading to tenogenic differentiation. These results may provide insights toward tendon regeneration therapies. PMID- 29471172 TI - Enhancing glioblastoma treatment using cisplatin-gold-nanoparticle conjugates and targeted delivery with magnetic resonance-guided focused ultrasound. AB - Glioblastoma (GBM) is the most common and aggressive primary brain tumor resulting in high rates of morbidity and mortality. A strategy to increase the efficacy of available drugs and enhance the delivery of chemotherapeutics through the blood brain barrier (BBB) is desperately needed. We investigated the potential of Cisplatin conjugated gold nanoparticle (GNP-UP-Cis) in combination with MR-guided Focused Ultrasound (MRgFUS) to intensify GBM treatment. Viability assays demonstrated that GNP-UP-Cis greatly inhibits the growth of GBM cells compared to free cisplatin and shows marked synergy with radiation therapy. Additionally, increased DNA damage through gammaH2AX phosphorylation was observed in GNP-UP-Cis treated cells, along with enhanced platinum concentrations. In vivo, GNP-UP-Cis greatly reduced the growth of GBM tumors and MRgFUS led to increased BBB permeability and GNP-drug delivery in brain tissue. Our studies suggest that GNP-Cis conjugates and MRgFUS can be used to focally enhance the delivery of targeted chemotherapeutics to brain tumors. PMID- 29471173 TI - Correlating growth mechanism and morphology in Cu-TCNQ organometallic complex: A microscopic study. AB - The structure-property correlation in the Cu-TCNQ organometallic complex is very important for explaining its unusual electrical, optical and magnetic properties. Consequently several morphological studies and their correlation with the properties of these materials can be found in the literature, although no systematic study of various morphologies with growth conditions and their correlation has been reported to the best of our knowledge. Therefore in this manuscript the interconversion of various morphologies is reported using electron and probe microscopies. A conventional Cu TEM grid acted as the copper source to form a Cu-TCNQ complex and the complex, which formed at the surface of the TEM grid. The complex thus prepared was characterized by FTIR and Raman spectroscopic techniques. The shifting of -CN from 2221 cm-1 (TCNQ) to 2201 cm-1 indicates formation of a complex and the identical nature of IR spectra in two phases indicates that they are polymorphs. The morphologies of Cu-TCNQ were followed through FE-SEM and TEM studies. Various morphologies such as needle, square tube, platelet etc. were observed as a function of time. A distinct transition from needle to platelet morphology was observed as the complex grew. The conductance of various morphologies in phase-I as well as phase-II were also measured and compared by Spreading Resistance Imaging (SRI) at different bias voltage i.e. 1 V, 3 V and 5 V. PMID- 29471174 TI - Characterizing gestational weight gain in a cohort of Indigenous Australian women. AB - OBJECTIVE: to determine the adequacy of gestational weight gain for a cohort of Indigenous Australian women and investigate whether it is associated with pre pregnancy body mass index. DESIGN: analysis of observational data collected from a longitudinal cohort study that follows Indigenous Australian women through pregnancy. SETTING: women recruited through antenatal clinics in regional and remote towns in NSW, Australia to the Gomeroi gaaynggal program. PARTICIPANTS: 110 pregnant women who either identified as being an Indigenous Australian or as carrying an Indigenous child. MEASUREMENTS AND FINDINGS: measurements included weight and height, self-reported pre-pregnancy weight and smoking status, parity and health conditions that may contribute to gestational weight gain, such as hypertensive or diabetic disorders. Compared to the 2009 Institute of Medicine recommendations for gestational weight gain and based on prepregnancy body mass index, the rate of adequate gestational weight gain in this cohort was very low (15%). 32% of women had inadequate weight gain and 54% had excessive weight gain. The highest rate of excessive gestational weight gain was found in overweight women (74%), with rates of 48% and 50% found in healthy and obese (all classes) categories, respectively. Parity (coefficient 4.5, p<0.01) and hypertension (coefficient 4.8, p = 0.04) were found to be significantly associated with gestational weight gain in mixed model linear regression. CONCLUSIONS: few women gained adequate gestational weight gain in this study. Culturally acceptable ways of addressing this issue are needed for this group of women, as inadequate and excessive rates of gestational weight gain have health implications for women and their offspring. IMPLICATIONS FOR PRACTICE: a systematic approach to addressing gestational weight gain within antenatal care is required, including asking about diet and exercise, for all women identifying as Indigenous Australian.

AB - US midwifery education is provided through graduate education for the CNM/CM and didactic education with apprenticeship for the CPM.

A lack of clinical sites for midwifery education is a significant challenge to all programs and a barrier to meeting the national maternity care provider shortage. PMID- 29471177 TI - Needs of students seeking careers in communication sciences and disorders and barriers to their success. AB - PURPOSE: The purpose of this study was to identify the needs for and barriers to success of underrepresented students in the Communication Sciences and Disorders field and to determine factors linked to student persistence and academic achievement. METHOD: An online survey was completed by 126 undergraduates pursuing graduate studies in Communication Sciences and Disorders. Data were subjected to Mann-Whitney U and Kruskal-Wallis H tests. RESULTS: Survey responses indicated that financial matters exerted the most influence on students' preparation for and number of choices for graduate-school applications. However, socioeconomic status was associated with needed financial support for paying tuition and completing the admission process. In addition, students at lower socioeconomic status reported spending fewer hours studying for tests and earned lower grade-point averages than peers who self-identified with a relatively high socioeconomic status. The findings also show a relationship between students' grade-point averages and family members' levels of education. The majority reported that mothers had earned the highest degree in their household, followed by siblings, themselves, and fathers. CONCLUSIONS: The findings suggest that students of low socioeconomic status were less academically prepared than those self-reporting a higher status. Moreover, the presence of a role model, such as a college-educated family member, may affect academic performance. Therefore, interventions for students at risk of not gaining admissions to graduate school include financial assistance and mentoring and advising programs.

PMID- 29471178 TI - A role for epistemic trust in speech-language pathology: A tutorial paper. AB - This paper provides an introduction to epistemic trust for speech-language pathologists (SLPs). 'Epistemic trust' describes a specific form of trust that an individual places in others when learning about the world, particularly the social world. To date, the relevance of epistemic trust to SLP clinical practice has received little theoretical or empirical attention. The aim of this paper is to define epistemic trust and explain its relationship with parent-child attachment and mentalization which have, in turn, been linked with language development and use. Suggestions are made for ways in which SLPs may encourage epistemic trust in clients, emphasizing the need to establish strong therapeutic alliances. The authors conclude that epistemic trust is an important consideration for SLPs and that further research exploring the relationship between epistemic trust and language skills is needed to better understand the interplay of these variables and inform clinical practice. PMID- 29471179 TI - The link between income inequality and health in Europe, adding strength dimensions of primary care to the equation. AB - Income inequality has been clearly associated with reduced population health. A body of evidence suggests that a strong primary care system may mitigate this negative association. The aim of this study is to assess the strength of the primary care system's effect on the inverse association between income inequality and health in Europe. Health is operationalised using four cross-sectional outcomes: self-rated health, life expectancy, mental well-being, and infant mortality. Strength of the primary care system is measured using the framework of the Primary Health Care Activity Monitor Europe, and income inequality by the Gini coefficient. Multiple regression models with interaction terms were used. The results confirm that especially the structure and continuity dimension of primary care strength can buffer the inverse association between income inequality and health. European policymakers should therefore focus on strengthening primary care systems in order to reduce inequity in health. PMID- 29471180 TI - Linking financial hardship throughout the life-course with psychological distress in old age: Sensitive period, accumulation of risks, and chain of risks hypotheses. AB - The primary objective was to investigate the life course hypotheses - sensitive period, chain of risks, and accumulation of risks - in relation to financial hardship and psychological distress in old age. We used two Swedish longitudinal surveys based on nationally representative samples. The first survey includes people 18-75 years old with multiple waves, the second survey is a longitudinal continuation, including people 76 + years old. The analytical sample included 2990 people at baseline. Financial hardship was assessed in childhood (retrospectively), at the mean ages of 54, 61, 70, and 81 years. Psychological distress (self-reported anxiety and depressive symptoms) was assessed at the same ages. Path analysis with WLSMV estimation was used. There was a direct path from financial hardship in childhood to psychological distress at age 70 (0.26, p = 0.002). Financial hardship in childhood was associated with increased risk of psychological distress and financial hardship both at baseline (age 54), and later. Financial hardship, beyond childhood, was not independently associated with psychological distress at age 81. Higher levels of education and employment decreased the negative effects of financial hardship in childhood on the risk of psychological distress and financial hardship later on. There was a bi directional relationship between psychological distress and financial hardship; support for health selection was slightly higher than for social causation. We found that psychological distress in old age was affected by financial hardship in childhood through a chain of risks that included psychological distress earlier in life. In addition, financial hardship in childhood seemed to directly affect psychological distress in old age, independent of other measured circumstances (i.e., chains of risks). Education and employment could decrease the effect of an adverse financial situation in childhood on later-life psychological distress. We did not find support for accumulation of risks when including tests of all hypotheses in the same model. PMID- 29471181 TI - Clinic access and teenage birth rates: Racial/ethnic and spatial disparities in Houston, TX. AB - Teenage motherhood is a pressing issue in the United States, and one that is disproportionately affecting racial/ethnic minorities. In this research, we examine the relationship between the distance to the nearest reproductive health clinic and teenage birth rates across all zip codes in Houston, Texas. Our primary data come from the Texas Department of State Health Services. We use spatial regression analysis techniques to examine the link between clinic proximity and local teenage birth rates for all females aged 15 to 19, and separately by maternal race/ethnicity. We find, overall, limited support for a connection between clinic distance and local teenage birth rates. However, clinics seem to matter most for explaining non-Hispanic white teenage birth rates, particularly in high-poverty zip codes. The racial/ethnic and economic variation in the importance of clinic distance suggests tailoring clinic outreach to more effectively serve a wider range of teenage populations. We argue social accessibility should be considered in addition to geographic accessibility in order for clinics to help prevent teenage pregnancy. PMID- 29471182 TI - The impact of vitamin A supplementation in childhood on adult outcomes: An exploration of mechanisms, timing of exposure, and heterogeneous effects. AB - There is now a critical threshold of evidence documenting the relationship between one's exposure to shocks in early life and outcomes in adulthood. Using Nepal's vitamin A supplementation program, this study provides additional insights on the mechanisms and differences in effects by the timing of the first exposure and across different groups. The program's sequential rollout between 1993 and 2001 and the age eligibility provide an exogenous variation in exposure to the program. I utilize that variation and data on more than 700,000 individuals from the 2011 census to estimate the program's causal effect on long term health and educational outcomes. I find that the program reduced the probability of having a disability but had no effect on educational outcomes. The positive effects on disability seem to have improved marriage prospects. The program also had different effects on individuals based on their timing of the exposure to the program, with an early exposure strengthening the positive health effects. Effects also differed by the individual's gender and ethnicity. They were more pronounced for men and individuals from traditionally advantaged ethnic groups. The findings suggest that long-term effects can differ even when the take up rate is similar for different segments of the population. PMID- 29471183 TI - Axillary motor nerve conduction study: Description of technique and provision of normative data. AB - BACKGROUND: Axillary nerve lesions can commonly occur secondary to trauma or brachial plexopathy. Our aim was to describe our technique of axillary nerve motor conduction studies and provide the respective normal values. METHODS: Active electrode was positioned over the most prominent portion of the middle deltoid, approximately 5-7 cm distal to the acromion. Reference electrode was positioned over the acromion. Ground electrode was placed between the active and the reference electrodes. Supramaximal stimulation was at the Erb's point. RESULTS: A total of 154 participants (61% male, age range 18-84) were included. There was a significant positive correlation between the subjects' age and the onset latency (Spearman's rho 0.312, p < 0.001) and a significant negative correlation between the participants' age and the CMAP (Spearman's rho -0.481, p < 0.001). For the total male population the lower normal value for the CMAP was 7.6 mV and the higher normal value for the onset latency was 5.0 ms. For the total female population the respective normal values were 6.5 mV and 3.5 ms. In order to detect an axillary nerve lesion, asymmetry of >40% in the CMAPS between the symptomatic and the asymptomatic side show a sensitivity of 95.2% and a specificity of 96.6%. CONCLUSION: We described our technique of axillary nerve motor conduction studies and provided the respective normal values stratified for age and gender. When suspecting an axillary nerve lesion it is always worth performing axillary motor NCS bilaterally and compare the CMAPs. PMID- 29471184 TI - Targeting metabotropic glutamate receptors for the treatment of neuroinflammation. AB - A large body of evidence suggests that neuroinflammation lies at the core of nearly all CNS disorders, including psychiatric disorders. Invading and local immune cells orchestrate the series of events that lead to either tissue repair or damage in response to neuroinflammation. Both lymphocytes and microglia express metabotropic glutamate (mGlu) receptors, which respond to glutamate or other endogenous activators (e.g. some kynurenine metabolites of tryptophan metabolism) influencing immune phenotype and the balance between pro-inflammatory and anti-inflammatory cytokines. Here, we offer an up-to-date on the role of individual mGlu receptor subtypes in the regulation of innate and adaptive immune response, highlighting the relevance of this information in the development of subtype-selective mGlu receptor ligands for treatment of CNS disorders.

AB - The ability to delay gratification at a young age is a predictor of psychological, cognitive, health, and academic later-life outcomes. This study aimed to extend earlier research and explore whether a metacognitive intervention, Wells' (1990) Attention Training Technique (ATT), could improve young children's ability to delay gratification compared to an active-control (Progressive Muscle Relaxation: PMR), and no-intervention group. One hundred and one children aged 5-6 years old were recruited from schools. Classes of children were randomly allocated to receive the ATT, PMR or no-intervention and tested at pre- and post-intervention on measures of delay of gratification (the Marshmallow Test) and verbal inhibition (Day/Night Task). Results showed that, even when covariates were controlled for, following ATT, children delayed gratification significantly longer than after PMR or no-intervention. ATT also improved verbal inhibition compared with the no-intervention group, whilst PMR did not. The results add to earlier findings; ATT appears to provide a simple and effective way of improving young children's ability to delay gratification which has previously been shown to predict positive outcomes in later-life. PMID- 29471186 TI - Maternal exposure to ambient PM10 during pregnancy increases the risk of congenital heart defects: Evidence from machine learning models. AB - Previous research suggested an association between maternal exposure to ambient air pollutants and risk of congenital heart defects (CHDs), though the effects of particulate matter <=10MUm in aerodynamic diameter (PM10) on CHDs are inconsistent. We used two machine learning models (i.e., random forest (RF) and gradient boosting (GB)) to investigate the non-linear effects of PM10 exposure during the critical time window, weeks 3-8 in pregnancy, on risk of CHDs. From 2009 through 2012, we carried out a population-based birth cohort study on 39,053 live-born infants in Beijing. RF and GB models were used to calculate odds ratios for CHDs associated with increase in PM10 exposure, adjusting for maternal and perinatal characteristics. Maternal exposure to PM10 was identified as the primary risk factor for CHDs in all machine learning models. We observed a clear non-linear effect of maternal exposure to PM10 on CHDs risk. Compared to 40MUgm 3, the following odds ratios resulted: 1) 92MUgm-3 [RF: 1.16 (95% CI: 1.06, 1.28); GB: 1.26 (95% CI: 1.17, 1.35)]; 2) 111MUgm-3 [RF: 1.04 (95% CI: 0.96, 1.14); GB: 1.04 (95% CI: 0.99, 1.08)]; 3) 124MUgm-3 [RF: 1.01 (95% CI: 0.94, 1.10); GB: 0.98 (95% CI: 0.93, 1.02)]; 4) 190MUgm-3 [RF: 1.29 (95% CI: 1.14, 1.44); GB: 1.71 (95% CI: 1.04, 2.17)]. Overall, both machine models showed an association between maternal exposure to ambient PM10 and CHDs in Beijing, highlighting the need for non-linear methods to investigate dose-response relationships. PMID- 29471187 TI - Mechanistic explanation of time-dependent cross-phenomenon based on quorum sensing: A case study of the mixture of sulfonamide and quorum sensing inhibitor to bioluminescence of Aliivibrio fischeri. AB - Cross-phenomenon in which the concentration-response curve (CRC) for a mixture crosses the CRC for the reference model has been identified in many studies, expressed as a heterogeneous pattern of joint toxic action. However, a mechanistic explanation of the cross-phenomenon has thus far been extremely insufficient. In this study, a time-dependent cross-phenomenon was observed, in which the cross-concentration range between the CRC for the mixture of sulfamethoxypyridazine (SMP) and (Z-)-4-Bromo-5-(bromomethylene)-2(5H)-furanone (C30) to the bioluminescence of Aliivibrio fischeri (A. fischeri) and the CRC for independent action model with 95% confidence bands varied from low-concentration to higher-concentration regions in a timely manner expressed the joint toxic action of the mixture changing with an increase of both concentration and time. Through investigating the time-dependent hormetic effects of SMP and C30 (by measuring the expression of protein mRNA, simulating the bioluminescent reaction and analyzing the toxic action), the underlying mechanism was as follows: SMP and C30 acted on the quorum sensing (QS) system of A. fischeri, which induced low concentration stimulatory effects and high-concentration inhibitory effects; in the low-concentration region, the stimulatory effects of SMP and C30 made the mixture produce a synergistic stimulation on the bioluminescence; thus, the joint toxic action exhibited antagonism. In the high-concentration region, the inhibitory effects of SMP and C30 in the mixture caused a double block in the loop circuit of the QS system; thus, the joint toxic action exhibited synergism. With the increase of time, these stimulatory and inhibitory effects of SMP and C30 were changed by the variation of the QS system at different growth phases, resulting in the time-dependent cross-phenomenon. This study proposes an induced mechanism for time-dependent cross-phenomenon based on QS, which may provide new insight into the mechanistic investigation of time-dependent cross-phenomenon, benefitting the environmental risk assessment of mixtures. PMID- 29471188 TI - Developing, cross-validating and applying regression models to predict the concentrations of faecal indicator organisms in coastal waters under different environmental scenarios. AB - This study developed, cross-validated and applied a regression-based model to predict concentrations of faecal indicator organisms (FIOs) under different environmental conditions in the North and South bays of Santa Catarina, South of Brazil. The model was developed using a database of FIO concentrations in seawater sampled at 50 sites and the validation was performed using a different database by comparing 288 pairs of measured and modelled results for 15 sites. The index of agreement between the model outputs and the FIO concentrations measured during the validation period was 66%; the mean average error was 0.43 log10 and the root mean square error was 0.58 log10 MPN.100mL-1. These validation results indicate that the model provides a fair representation of the FIO contamination in the bays for the meteorological conditions under which the model was trained. The simulation of different scenarios showed that under typical levels of resident human population in the catchments and median rainfall and solar radiation conditions, the median FIO concentration in the bays is 0.4 MPN.100mL-1. Under extreme meteorological conditions, the combined effect of high rainfall and low solar radiation increased FIO concentrations up to 5 log10 MPN.100mL-1. The simulated scenarios also show that increases in resident population during the summer tourist season and average rainfall concentrations do not increase median FIO concentrations in the bays relative to periods of time with average population, possibly because of higher bacterial die-off in the waters. The models can be an effective tool for management of human health risks in bathing and shellfish waters impacted by sewage pollution. PMID- 29471189 TI - Concentrations of trace elements and PCDD/Fs around a municipal solid waste incinerator in Girona (Catalonia, Spain). Human health risks for the population living in the neighborhood. AB - Previously to the modernization of the municipal solid waste incinerator (MSWI) of Campdora (Girona, Catalonia, Spain) two sampling campaigns (2015 and 2016) were conducted. In each campaign, 8 soil and 4 air samples (PM10 and total particle phase and gas phase) were collected. The levels of As, Cd, Co, Cr, Cu, Hg, Mn, Ni, Pb, Sb, Sn, Tl and V, and PCDD/Fs were analysed at different distances and wind directions around the MSWI. Environmental levels of trace elements and PCDD/Fs were used to assess exposure and health risks (carcinogenic and non-carcinogenic) for the population living around the facility. In soils, no significant differences were observed for trace elements and PCDD/Fs between both campaigns. In air, significant higher levels of As, Cd, Co, Mn, Ni, Pb, Tl and V were detected in 2016. Regarding soil levels, only Cd (distances) and As, Cu, Mn, and Ni (wind directions) showed significant differences. No differences were noted in the concentrations of trace elements and PCDD/Fs in air levels with respect to distances and directions to the MSWI. No differences were registered in air levels (elements and PCDD/Fs) between points influenced by MSWI emissions and background point. However some differences in congener profile were noted regarding from where back-trajectories come from (HYSPLIT model results), pointing some influence of Barcelona metropolitan area. The concentrations of trace elements and PCDD/Fs were similar -or even lower- than those reported around other MSWIs in Catalonia and various countries. Non-carcinogenic risks were below the safety limit (HQ<1). In turn, carcinogenic risks due to exposure to trace elements and PCDD/Fs were in acceptable ranges, according to national and international standard regulations. PMID- 29471190 TI - Interdecadal changes of summer aerosol pollution in the Yangtze River Basin of China, the relative influence of meteorological conditions and the relation to climate change. AB - Winter is a season of much concern for aerosol pollution in China, but less concern for pollution in the summertime. There are even less concern and larger uncertainty about interdecadal changes in summer aerosol pollution, relative influence of meteorological conditions, and their links to climate change. Here we try to reveal the relation among interdecadal changes in summer's most important circulation system affecting China (East Asian Summer Monsoon-EASM), an index of meteorological conditions (called PLAM, Parameter Linking Air Quality and Meteorological Elements, which is almost linearly related with aerosol pollution), and aerosol optical depth (AOD) in the middle and lower reaches of the Yangtze River (M-LYR) in central eastern China during summertime since the 1960's. During the weak monsoon years, the aerosol pollution load was heavier in the M-LYR and opposite in the strong monsoon years mainly influenced by EASM and associated maintenance position of the anti-Hadley cell around 115 degrees E. The interdecadal changes in meteorological conditions and their associated aerosol pollution in the context of such climate change have experienced four periods since the 1960's, which were a relatively large decreased period from 1961 to 1980, a large rise between 1980 and 1999, a period of slow rise or maintenance from 1999 to 2006, and a relatively rapid rise between 2006 and 2014. Among later three pollution increased periods, about 51%, 25% and 60% of the aerosol pollution change respectively come from the contribution of worsening weather conditions, which are found to be greatly affected by changes in EASM. PMID- 29471191 TI - Peak knee biomechanics and limb symmetry following unilateral anterior cruciate ligament reconstruction: Associations of walking gait and jump-landing outcomes. AB - BACKGROUND: Aberrant walking-gait and jump-landing biomechanics may influence the development of post-traumatic osteoarthritis and increase the risk of a second anterior cruciate ligament injury, respectively. It remains unknown if individuals who demonstrate altered walking-gait biomechanics demonstrate similar altered biomechanics during jump-landing. Our aim was to determine associations in peak knee biomechanics and limb-symmetry indices between walking-gait and jump landing tasks in individuals with a unilateral anterior cruciate ligament reconstruction. METHODS: Thirty-five individuals (74% women, 22.1 [3.4] years old, 25 [3.89] kg/m2) with an anterior cruciate ligament reconstruction performed 5-trials of self-selected walking-gait and jump-landing. Peak kinetics and kinematics were extracted from the first 50% of stance phase during walking-gait and first 100 ms following ground contact for jump-landing. Pearson product moment (r) and Spearman's Rho (rho) analyses were used to evaluate relationships between outcome measures. Significance was set a priori (P <= 0.05). FINDINGS: All associations between walking-gait and jump-landing for the involved limb, along with the majority of associations for limb-symmetry indices and the uninvolved limb, were negligible and non-statistically significant. There were weak significant associations for instantaneous loading rate (rho = 0.39, P = 0.02) and peak knee abduction angle (rho = 0.36, p = 0.03) uninvolved limb, as well as peak abduction displacement limb-symmetry indices (rho= - 0.39, p = 0.02) between walking-gait and jump-landing. INTERPRETATION: No systematic associations were found between walking-gait and jump-landing biomechanics for either limb or limb-symmetry indices in people with unilateral anterior cruciate ligament reconstruction. Individuals with an anterior cruciate ligament reconstruction who demonstrate high-involved limb loading or asymmetries during jump-landing may not demonstrate similar biomechanics during walking-gait.

PMID- 29471192 TI - The effect of magnolol on Ca2+ homeostasis and its related physiology in human oral cancer cells. AB - OBJECTIVE: Magnolol, a polyphenol compound from herbal medicines, was shown to alter physiology in various cell models. However, the effect of magnolol on Ca2+ homeostasis and its related physiology in oral cancer cells is unclear. This study examined whether magnolol altered Ca2+ signaling and cell viability in OC2 human oral cancer cells. METHODS: Cytosolic Ca2+ concentrations ([Ca2+]i) in suspended cells were measured by using the fluorescent Ca2+-sensitive dye fura-2. Cell viability was examined by 4-[3-[4-lodophenyl]-2-4(4-nitrophenyl)-2H-5 tetrazolio-1,3-benzene disulfonate] water soluble tetrazolium-1 (WST-1) assay. RESULTS: Magnolol at concentrations of 20-100 MUM induced [Ca2+]i rises. Ca2+ removal reduced the signal by approximately 50%. Magnolol (100 MUM) induced Mn2+ influx suggesting of Ca2+ entry. Magnolol-induced Ca2+ entry was partially suppressed by protein kinase C (PKC) regulators, and inhibitors of store-operated Ca2+ channels. In Ca2+-free medium, treatment with the endoplasmic reticulum Ca2+ pump inhibitor 2,5-di-tert-butylhydroquinone (BHQ) abolished magnolol-evoked [Ca2+]i rises. Conversely, treatment with magnolol abolished BHQ-evoked [Ca2+]i rises. Inhibition of phospholipase C (PLC) with U73122 partially inhibited magnolol-induced [Ca2+]i rises. Magnolol at 20-100 MUM decreased cell viability, which was not reversed by pretreatment with the Ca2+ chelator 1,2-bis(2 aminophenoxy)ethane-N,N,N',N'-tetraacetic acid-acetoxymethyl ester (BAPTA/AM). CONCLUSIONS: Together, in OC2 cells, magnolol induced [Ca2+]i rises by evoking partially PLC-dependent Ca2+ release from the endoplasmic reticulum and Ca2+ entry via PKC-sensitive store-operated Ca2+ entry. Magnolol also caused Ca2+ independent cell death. Therefore, magnolol-induced cytotoxicity may not be involved in activation mechanisms associated with intracellular Ca2+ mobilization in oral cancer cells. PMID- 29471194 TI - Relationship between postural control and muscle activity during a handstand in young and adult gymnasts. AB - The aim of this study was to evaluate the relationship between muscle activity and inter-muscle contributions patterns and postural control during a handstand. Additionally, outcomes were compared between young and adult gymnasts (mean +/- SD: 13.9 +/- 0.7 and 23 +/- 3 years respectively). Participants performed three trials of a 10 s handstand on a force platform with simultaneous EMG signal recording at the upper and lower limbs. Adult gymnasts demonstrated significantly better postural control in each studied variable. The wrist flexors demonstrated the highest relative mean (60%) and peak (200%) EMG activity of all muscle groups studied. Wrist flexor activity was also highly correlated with postural control variables in both groups. The trapezius descendens and wrist flexor muscles demonstrated the highest contribution (20-26% and 25.5-28% respectively), followed by anterior deltoid (15-18%) and triceps brachii (13-16%) in both groups. The young gymnast group demonstrated significantly greater mean relative muscle activity at the triceps brachii, biceps brachii and rectus femoris compared with the adult group (88% (p = 0.023), 150% (p = 0.003) and 75% (p = 0.039) respectively). To conclude, despite comparable inter-muscle contributions during a handstand, young and adult gymnasts demonstrated a different relationship between muscle activity and postural control variables. PMID- 29471195 TI - GXNOR-Net: Training deep neural networks with ternary weights and activations without full-precision memory under a unified discretization framework. AB - Although deep neural networks (DNNs) are being a revolutionary power to open up the AI era, the notoriously huge hardware overhead has challenged their applications. Recently, several binary and ternary networks, in which the costly multiply-accumulate operations can be replaced by accumulations or even binary logic operations, make the on-chip training of DNNs quite promising. Therefore there is a pressing need to build an architecture that could subsume these networks under a unified framework that achieves both higher performance and less overhead. To this end, two fundamental issues are yet to be addressed. The first one is how to implement the back propagation when neuronal activations are discrete. The second one is how to remove the full-precision hidden weights in the training phase to break the bottlenecks of memory/computation consumption. To address the first issue, we present a multi-step neuronal activation discretization method and a derivative approximation technique that enable the implementing the back propagation algorithm on discrete DNNs. While for the second issue, we propose a discrete state transition (DST) methodology to constrain the weights in a discrete space without saving the hidden weights. Through this way, we build a unified framework that subsumes the binary or ternary networks as its special cases, and under which a heuristic algorithm is provided at the website https://github.com/AcrossV/Gated-XNOR. More particularly, we find that when both the weights and activations become ternary values, the DNNs can be reduced to sparse binary networks, termed as gated XNOR networks (GXNOR-Nets) since only the event of non-zero weight and non-zero activation enables the control gate to start the XNOR logic operations in the original binary networks. This promises the event-driven hardware design for efficient mobile intelligence. We achieve advanced performance compared with state-of-the art algorithms. Furthermore, the computational sparsity and the number of states in the discrete space can be flexibly modified to make it suitable for various hardware platforms. PMID- 29471196 TI - Distant supervision for neural relation extraction integrated with word attention and property features. AB - Distant supervision for neural relation extraction is an efficient approach to extracting massive relations with reference to plain texts. However, the existing neural methods fail to capture the critical words in sentence encoding and meanwhile lack useful sentence information for some positive training instances. To address the above issues, we propose a novel neural relation extraction model. First, we develop a word-level attention mechanism to distinguish the importance of each individual word in a sentence, increasing the attention weights for those critical words. Second, we investigate the semantic information from word embeddings of target entities, which can be developed as a supplementary feature for the extractor. Experimental results show that our model outperforms previous state-of-the-art baselines. PMID- 29471197 TI - Extracting cardiac dynamics within ECG signal for human identification and cardiovascular diseases classification. AB - Cardiac characteristics underlying the time/frequency domain features are limited and not comprehensive enough to reflect the temporal/dynamical nature of ECG patterns. This paper proposes a dynamical ECG recognition framework for human identification and cardiovascular diseases classification via a dynamical neural learning mechanism. The proposed method consists of two phases: a training phase and a test phase. In the training phase, cardiac dynamics within ECG signals is extracted (approximated) accurately by using radial basis function (RBF) neural networks through deterministic learning mechanism. The obtained cardiac system dynamics is represented and stored in constant RBF networks. An ECG signature is then derived from the extracted cardiac dynamics along the periodic ECG state trajectories. A bank of estimators is constructed using the extracted cardiac dynamics to represent the trained gait patterns. In the test phase, recognition errors are generated and taken as the similarity measure by comparing the cardiac dynamics of the trained ECG patterns and the dynamics of the test ECG pattern. Rapid recognition of a test ECG pattern begins with measuring the state of test pattern, and automatically proceeds with the evolution of the recognition error system. According to the smallest error principle, the test ECG pattern can be rapidly recognized. This kind of cardiac dynamics information represents the beat to-beat temporal change of ECG modifications and the temporal/dynamical nature of ECG patterns. Therefore, the amount of discriminability provided by the cardiac dynamics is larger than the original signals. This paper further discusses the extension of the proposed method for cardiovascular diseases classification. The constructed recognition system can distinguish and assign dynamical ECG patterns to predefined classes according to the similarity of cardiac dynamics. Experiments are carried out on the FuWai and PTB ECG databases to demonstrate the effectiveness of the proposed method. PMID- 29471198 TI - Gaze patterns reveal how situation models and text representations contribute to episodic text memory. AB - When recalling something you have previously read, to what degree will such episodic remembering activate a situation model of described events versus a memory representation of the text itself? The present study was designed to address this question by recording eye movements of participants who recalled previously read texts while looking at a blank screen. An accumulating body of research has demonstrated that spontaneous eye movements occur during episodic memory retrieval and that fixation locations from such gaze patterns to a large degree overlap with the visuospatial layout of the recalled information. Here we used this phenomenon to investigate to what degree participants' gaze patterns corresponded with the visuospatial configuration of the text itself versus a visuospatial configuration described in it. The texts to be recalled were scene descriptions, where the spatial configuration of the scene content was manipulated to be either congruent or incongruent with the spatial configuration of the text itself. Results show that participants' gaze patterns were more likely to correspond with a visuospatial representation of the described scene than with a visuospatial representation of the text itself, but also that the contribution of those representations of space is sensitive to the text content. This is the first demonstration that eye movements can be used to discriminate on which representational level texts are remembered and the findings provide novel insight into the underlying dynamics in play. PMID- 29471199 TI - Statistical modelling of Fat, Oil and Grease (FOG) deposits in wastewater pump sumps. AB - The accumulation of FOG (Fat, Oil and Grease) deposits in sewer pumping stations results in an increase in maintenance costs, malfunctioning of pumps and, a potential increase of wastewater spills in receiving open water bodies. It is thought that a variety of parameters (e.g. geometry of the pump sump, pump operation, socioeconomic parameters of the catchment) influences the built-up of FOG. Based on a database containing data of 126 pumping stations located in five Dutch municipalities a statistical model was built. It is shown that 3 parameters are most significant in explaining the occurrence of FOG deposits: mean income of the population in a catchment, the amount of energy (kinetic and potential) per m3 per day and the density of restaurants, bars and hotels in a catchment. Further it is shown that there are significant differences between municipalities that can be traced back to the local 'design paradigm'. For example, in Amsterdam, the design philosophy of discharging in the pump sump under the water surface (and hence maintaining a low level of turbulence in the pump sump) results in an increase of the probability of the formation of FOG. PMID- 29471200 TI - A review on recent progress in the detection methods and prevalence of human enteric viruses in water. AB - Waterborne human enteric viruses, such as noroviruses and adenoviruses, are excreted in the feces of infected individuals and transmitted via the fecal-oral route including contaminated food and water. Since viruses are normally present at low concentrations in aquatic environments, they should be concentrated into smaller volumes prior to downstream molecular biological applications, such as quantitative polymerase chain reaction (qPCR). This review describes recent progress made in the development of concentration and detection methods of human enteric viruses in water, and discusses their applications for providing a better understanding of the prevalence of the viruses in various types of water worldwide. Maximum concentrations of human enteric viruses in water that have been reported in previous studies are summarized to assess viral abundances in aquatic environments. Some descriptions are also available on recent applications of sequencing analyses used to determine the genetic diversity of viral genomes in water samples, including those of novel viruses. Furthermore, the importance and significance of utilizing appropriate process controls during viral analyses are discussed, and three types of process controls are considered: whole process controls, molecular process controls, and (reverse transcription (RT)-)qPCR controls. Although no standards have been established for acceptable values of virus recovery and/or extraction-(RT-)qPCR efficiency, use of at least one of these appropriate control types is highly recommended for more accurate interpretation of observed data. PMID- 29471201 TI - Facile synthesis of Bi2MoO6/reduced graphene oxide composites as anode materials towards enhanced lithium storage performance. AB - Bi2MoO6/reduced graphene oxide (Bi2MoO6/rGO) composites were fabricated by a facile one-pot hydrothermal approach, in which Bi2MoO6 nanosheets and rGO were simultaneously obtained. The structure and composition of the as-synthesized Bi2MoO6 and Bi2MoO6/rGO materials were characterized via FT-IR, BET, TGA, XRD, TEM, SEM and XPS analyses, and the electrochemical performance of Bi2MoO6/rGO as an anode in a lithium-ion battery was investigated. Compared with pristine Bi2MoO6, the Bi2MoO6/rGO composites have higher capacities, better cycle stability and higher rates. For a current density of 100 mA g-1, the initial discharge capacities of the Bi2MoO6/rGO-20 and pristine Bi2MoO6 were 1049.6 mAh g 1 and 528.5 mAh g-1, respectively. After 100 cycles, the capacity retention for the Bi2MoO6/rGO-20 and pristine Bi2MoO6 were respectively 80.4% and 30.7% using the 2nd cycle capacities (895.8 and 402.4 mAh g-1) as references. The enhanced electrochemical performance can be ascribed to the synergistic effect of the Bi2MoO6 and rGO sheets, which dramatically improves the conductivities of the Bi2MoO6/rGO anodes. In addition, the rGO sheets also supply electron transfer routes for the anode and suppress volume changes of Bi2MoO6 nanosheets during the charge-discharge cycles. PMID- 29471202 TI - Conductive micropatterned polyurethane films as tissue engineering scaffolds for Schwann cells and PC12 cells. AB - Controlling cellular alignment and elongation has been demonstrated as an important parameter for developing nerve tissue engineering scaffolds. Many approaches have been developed to guide cellular orientation for nerve regeneration such as micropatterning techniques. However, most of materials used for developing micropatterning scaffolds lack of bioactivity and biofunctionability. Here we present a functional conductive micropatterned scaffold based on bioactive conductive biodegradable polyurethane prepared using a micro-molding technique. These conductive micropatterned scaffolds are able to not only induce the Schwann cells (SCs) alignment and elongation by the micropatterned surface but also enhance the nerve growth factor (NGF) gene expression of SCs by the bioactivity of these materials. Additionally, the combined effect of the bioactivity of such conductive materials and the micropatterned structure also dramatically promotes the neurite extension and elongation of PC12 cells in a highly aligned direction. These data suggest that these conductive micropatterned scaffolds that easily control cellular orientation and organization, and dramatically enhance NGF gene expression and significantly induce the neurite extension of PC12 cells, have a great potential for nerve regeneration applications. PMID- 29471203 TI - Significance of an in-situ generated boundary film on tribocorrosion behavior of polymer-metal sliding pair. AB - Polymer composites have a high potential for applications as tribo-materials exposed to sea water owing to their self-lubrication characteristic and high chemical stability. In the present work, tribological behaviors of polyetheretherketone (PEEK) composites rubbing with stainless steel in sea water were explored using a pin-on-disc tribometer integrated with a potentiostat for electrochemical control. It was demonstrated that further adding 5 vol% hexagonal boron nitride (h-BN) nanoparticles into PEEK reinforced with short carbon fibers (SCF) significantly enhanced the wear resistance. Moreover, the stainless steel exhibited significantly enhanced tribocorrosion resistance when rubbing with the hybrid nanocomposite, in comparison to the sliding against PEEK filled only with SCF. Nanostructures of the boundary films formed on the steel surface were comprehensively investigated. It was manifested that tribo-chemistry products of h-BN, i.e. H3BO3 and B2O3, were arrayed in a closely packed boundary film. It seems that inclusion of layer-structured H3BO3 and B2O3 improved the resilience of the boundary film. The continuous boundary film covering the steel surface provided a lubrication effect and strengthened the passivation layer. A new route for enhancing simultaneously tribological and corrosion resistance of polymer metal pairs by controlling in-situ tribo-chemistry was thus proposed. PMID- 29471204 TI - Fabrication of a solution-gated transistor based on valinomycin modified iron oxide nanoparticles decorated zinc oxide nanorods for potassium detection. AB - There are considerable interests to detect and monitor the abnormal level of minerals in water for avoiding/preventing any toxic effects after consumption. Herein, we report the fabrication of solution-gated field-effect-transistor (FET) based potassium sensor using iron oxide nanoparticles (Fe2O3 NPs) modified directly grown zinc oxide nanorods (ZnO NRs). The Fe2O3 NPs modification of ZnO NRs provided stability to nanorods surface and improved surface area for valinomycin immobilization. As-fabricated potassium sensor (valinomycin-Fe2O3 NPs ZnO NRs/SiO2/Si) provided enhanced current response with increasing potassium concentration. During sensing measurements, FET sensor showed high sensitivity (4.65 MUA/MUM/cm2) in the linear range of 0.1 MUM to 125 MUM, low limit of detection (~0.04 MUM), good stability, excellent reproducibility, and favorable selectivity. Thus, good sensing performance of the FET based potassium sensor presents it as simple, low-cost, and convenient device for selective detection of potassium in solution. PMID- 29471205 TI - Fabrication of bioinspired, self-cleaning superliquiphilic/phobic stainless steel using different pathways. AB - The mechanical properties, corrosion-resistance, and aesthetics of stainless steel make it one of the most important and widely used materials worldwide in the construction, food, and transportation industries just to name a few. In this paper we demonstrate how these properties can be further enhanced by changing the hydrophilic stainless steel surface to be superhydrophilic, superhydrophobic, or superliquiphobic. Creation of these functional surfaces requires hierarchical roughness and chemistry. Roughness is created using various pathways including sandblasting, chemical etching, and nanocomposite coatings. Surface chemistry is controlled using methylchlorosilane, nanoparticles in methylphenyl silicone, and fluorosilane treatment. The broad approach allows for direct comparisons of these pathways. Resulting treatments can create stainless steel surfaces with a hexadecane contact angle of 155 degrees and tilt angle of 7-10 degrees . Discussions of rust-avoidance and coating through condensation reactions are included. Enhanced properties of self-cleaning behavior, anti-icing behavior, wear resistance, and bending resistance are demonstrated on stainless steel 304 L. Stainless steel 430, which is more corrosion prone than stainless steel 304 L, is then used to demonstrate transferability of the treatments and corrosion resistance imparted through superliquiphobicity.

AB - BACKGROUND: Research indicates that anxiety during pregnancy may be a risk factor for the development of alterations in the mental health of the pregnant woman and of obstetric complications. OBJECTIVE: to investigate the effect of music therapy on maternal anxiety, before and after a non-stress test (NST), and the effect of maternal anxiety on the birthing process and birth size. METHODS: 409 nulliparous women coming for routine prenatal care were randomized in the third trimester to receive either music therapy (n = 204) or no music therapy (n = 205) during an NST. Maternal anxiety was assessed using the Spielberger State-Trait Anxiety Inventory before and after the NST. RESULTS: After the NST, the women from the music group showed significantly lower scores in state anxiety (OR = 0.87; p < 0.001) as well as trait anxiety (p < 0.001) than the control group. Furthermore, the pregnant women from the music group presented lower levels of state-trait anxiety than the control group in relation to the variables of birth process, and higher birth weight and chest circumference in the newborn (OR = 3.5 and OR = 0.81, respectively; p < 0.05). LIMITATIONS: This study was limited by the fact that it was a single-centre study; the observers conducting the NST were not blinded to the allocation, although neither midwife had any knowledge of the maternal anxiety scores, and we could not apply the double-blind method due to the nature of the observation. CONCLUSIONS: Our findings confirm that music therapy intervention during pregnancy could reduce elevated state-trait anxiety levels during the third trimester. Further research into the influence of music therapy as intervention on maternal anxiety and on the birthing process and birth size is required during pregnancy.

AB - OBJECTIVES: This study aimed to examine the role of falls efficacy in the relationship between the locomotive function and quality of life. METHODS: From March to May in 2016, we conducted a cross-sectional survey among 830 community residents aged >=60 years from Jinzhou,China.GLFS-25 (25-question Geriatric Locomotive Function Scale), FES-I(International edition of Falls Efficacy Scale),and SF-12 (12-item Short Form Health Survey) were used to estimate locomotive function, falls efficacy and quality of life, respectively. The higher score of GLFS-25, the worse the locomotive function. RESULTS: Median age was 68.69 years (ranges 60-88). Locomotive function, falls efficacy and quality of life all presented a linear relationship within each other, locomotive function score was negatively correlated with falls efficacy score (-0.461, P < 0.01). locomotive function score was negatively correlated with quality of life score ( 0.523, P < 0.01).Falls efficacy score was positively correlated with quality of life score (0.415, P < 0.01).Falls efficacy exerted both a mediating and moderating role between locomotive function and quality of life, and the mediation effect accounted for 45.5% of the total effect. CONCLUSIONS: Poorer locomotive function was associated with poorer quality of life, and greater falls efficacy was associated with better quality of life. In addition, falls efficacy was demonstrated to be both a mediator and moderator variable in the linkage between locomotive function and quality of life. Aged care professional practitioners and our policy makers should strengthen the awareness of the psychological role of the elderly falls efficacy. PMID- 29471208 TI - Understanding biopharmaceutical production at single nucleotide resolution using ribosome footprint profiling. AB - Biopharmaceuticals such as monoclonal antibodies have revolutionised the treatment of a variety of diseases. The production of recombinant therapeutic proteins, however, remains expensive due to the manufacturing complexity of mammalian expression systems and the regulatory burden associated with administrating these medicines to patients in a safe and efficacious manner. In recent years, academic and industrial groups have begun to develop a greater understanding of the biology of host cell lines, such as Chinese hamster ovary (CHO) cells and utilise that information for process development and cell line engineering. In this review, we focus on ribosome footprint profiling (RiboSeq), an exciting next generation sequencing (NGS) method that provides genome-wide information on translation, and discuss how its application can transform our understanding of therapeutic protein production. PMID- 29471209 TI - Genetic engineering of host organisms for pharmaceutical synthesis. AB - Pharmaceutical production hosts may be derived from almost any organism, from Chinese Hamster Ovary (CHO) cell lines to isolated actinomycetes. Each host can be improved, historically only through adaptive evolution. Recently, the maturation of organism engineering has expanded the available models, methods, and tools for altering host phenotypes. New tools like CRISPR-associated endonucleases promise to enable precise cellular reprogramming and to access previously intractable hosts. In this review, we discuss the most recent advances in engineering several types of pharmaceutical production hosts. These include model organisms, potential platform hosts with advantageous metabolism or physiology, specialized producers capable of unique biosynthesis, and CHO, the most widely used recombinant protein production host. To realize improved engineered hosts, an increasing number of approaches involving DNA sequencing and synthesis, host rewriting technologies, computational methods, and organism engineering strategies must be used. Integrative workflows that enable application of the right combination of methods to the right production host could enable economical production solutions for emerging human health treatments.

PMID- 29471211 TI - Exogenous nanosilica improves germination and growth of cucumber by maintaining K+/Na+ ratio under elevated Na+ stress. AB - The current work was aimed to elucidate the role of engineered nanosilica (SiNPs) particles to mitigate the damaging impacts of Na+-derived salinity on cucumber (Cucumis sativus) Beit Alpha variety by conducting in vitro experiments applying various Na+ concentrations i.e. 0, 1000, 2000, 3000, 4000 and 5000 mg L-1. By treating seeds and seedlings, respectively, of cucumber with SiNPs (0, 100, 200 and 300 ppm) and subsequent determination some germination and vegetative parameters as well as chemical analysis of seedlings, we verified that SiNPs succeeded to alleviate the detrimental effects of high Na+ salinity by increasing germination parameters and vegetative growth of cucumber seedlings. Even as little as 100 ppm of N-Si results in considerable improvement of seed germination and seedlings growth of cucumber compared to the control, while 200 ppm was optimal among the doses tested. At 5000 mg Na+ L-1, applying SiNPs with 200 ppm increased final germination percentage by 101% over control, vigor index by 101%, germination rate index by 116%, germination index by 110%, fresh mass by 13%, K+/Na+ ratio by 77%, shoot dry mass by 384%, root dry mass by 304% and plant height by 70%. The results mentioned in this paper obviously outline the large practical relevance of SiNPs and imply that applying of SiNPs for cucumber seeds and seedlings under high Na+-derived salinity enhances germination and growth as a result for decreasing Na+ uptake and sequentially improves high K+/Na+ ratio. PMID- 29471212 TI - Nodular fasciitis mimicking a soft tissue sarcoma - A case report. AB - INTRODUCTION: Nodular Fasciitis, also known as infiltrative or pseudosarcomatous fasciitis, is a benign soft tissue tumour of fibroblastic/myofibroblastic differentiation, that was first described in 1955 by Konwaler et al. PRESENTATION OF CASE: This is a case report of a 27-year old male with complaints of a swelling in the right axilla for 2 and 1/2 years measuring 12 cm * 10 cm. Chest X Ray was normal. Magnetic Resonance Imaging of the right arm and chest showed an irregular mass in the axilla in the muscular-subcutaneous plane measuring 10.8 cm * 8.8 cm * 12 cm, with no neural involvement. Magnetic Resonance Angiogram showed feeders from the branches of the Right Subclavian and Right Axillary Artery and venous drainage into the Right Subclavian Vein. USG guided biopsy was done which showed benign spindle cell neoplasm. Patient underwent wide local excision under general anesthesia. The specimen was sent for histopathological examination which showed histological and immunohistochemical features in favour of Nodular Fasciitis. DISCUSSION: Most nodular fasciitis lesions are solitary and occur in adults 20-40 years of age. Nodular fasciitis affects both men and women with equal frequency. Differential diagnosis of nodular fasciitis includes, fibrosarcoma, fibroma, fibrous histiocytoma, and desmoids and histopathology and immunohistochemistry play a key role in identifying the condition. CONCLUSION: Owing to the size, location and findings of the Magnetic Resonance Angiogram we initially suspected a Soft Tissue Sarcoma, but to our surprise, on further investigation the mass was revealed to be Nodular Fasciitis. PMID- 29471213 TI - Cerebellar gray matter explains bimanual coordination performance in children and older adults. AB - The cerebellum appears to undergo late maturation in children and early decline at older age. Whether these age-related changes affect bimanual coordination performance remains unclear at best. Here, we identified the ages at which bimanual coordination performance stops improving and starts declining. In an independent cohort, we defined brain regions of interest involved in bimanual coordination using functional magnetic resonance imaging. We used these regions of interest to investigate the extent to which the gray matter of cerebellar and other brain regions explains bimanual coordination performance from 10- to 80 year-olds. Results showed that bimanual coordination performance starts declining from the age of 40 years. In participants aged 10-20 years, cerebellar lobule VI was the only significant brain predictor of bimanual coordination performance. In participants aged 60-80 years, this cerebellar region, together with the primary sensorimotor cortex, formed a group of strongest predictors. These results from 2 independent samples (10-20 and 60-80 years) suggest that cerebellar lobule VI is critical for the development and preservation of bimanual coordination skills in children and older adults, respectively. In addition, post hoc analyses suggested that the primary motor cortex mediated the adverse effect of age on bimanual coordination performance in older adults. PMID- 29471216 TI - Toward true closed-loop neuromodulation: artifact-free recording during stimulation. AB - Closed-loop and responsive neuromodulation systems improve open-loop neurostimulation by responding directly to measured neural activity and providing adaptive, on-demand therapy. To be effective, these systems must be able to simultaneously record and stimulate neural activity, a task made difficult by persistent stimulation artifacts that distort and obscure underlying biomarkers. To enable simultaneous stimulation and recording, several techniques have been proposed. These techniques involve artifact-preventing system configurations, resilient recording front-ends, and back-end signal processing for removing recorded artifacts. Co-designing and integrating these artifact cancellation techniques will be key to enabling neuromodulation systems to stimulate and record at the same time. Here, we review the state-of-the-art for these techniques and their role in achieving artifact-free neuromodulation. PMID- 29471214 TI - Joint associations of beta-amyloidosis and cortical thickness with cognition. AB - In 1164 cognitively unimpaired persons, aged 50-95 years, from the population based Mayo Clinic Study of Aging, we examined the relationships of baseline cognition and cognitive changes across the full range of cortical thickness of an Alzheimer signature region of interest and global beta-amyloid levels measured by Pittsburgh compound B positron emission tomography (PIB PET) standardized uptake value ratio (SUVR). In machine-learning models accounting for both biomarkers simultaneously, worsening biomarker values were additive and associated with lower baseline global cognition and greater subsequent decline in global cognition. Associations between Alzheimer's disease signature cortical thickness or PIB PET beta-amyloid SUVR and baseline cognition were mainly linear. Lower Alzheimer's disease signature cortical thickness values across the entire range of thickness predicted future decline in global cognitive scores, demonstrating its close relationship to cognitive functioning. PIB PET beta-amyloid SUVR also predicted cognitive decline across its full range, even when cortical thickness was accounted for. PIB PET beta-amyloid's relationship to cognitive decline was nonlinear, more prominent at lower beta-amyloid levels and less prominent at higher beta-amyloid levels. PMID- 29471215 TI - Genetic approaches to access cell types in mammalian nervous systems. AB - Understanding brain circuit organization and function requires systematic dissection of its cellular components. With vast cell number and diversity, mammalian nervous systems present a daunting challenge for achieving specific and comprehensive cell type access-prerequisite to circuit analysis. Genetic approaches in the mouse have relied on germline engineering to access marker defined cell populations. Combinatorial strategies that engage marker intersection, anatomy and projection pattern (e.g. antero-grade and retro-grade viral vectors), and developmental lineage substantially increase the specificity of cell type targeting. While increasing number of mouse cell types are becoming experimentally accessible, comprehensive coverage requires larger coordinated efforts with strategic infrastructural and fiscal planning. CRISPR-based genome editing may enable cell type access in other species, but issues of time, cost and ethics remain, especially for primates. Novel approaches that bypass the germline, such as somatic cell engineering and cell surface-based gene delivery, may reduce the barrier of genetic access to mammalian cell types. PMID- 29471217 TI - How gender norms are reinforced through violence against adolescent girls in two conflict-affected populations. AB - Violence against women and girls is a global concern, and particularly salient in humanitarian settings. Successful efforts to prevent gender-based violence in humanitarian settings must address a wide range of issues, from discriminatory laws to explicit community support for violence, and yet, at the core of these efforts is reducing oppressive gender and social norms. This study examined local attitudes towards and social norms around responding to physical and sexual abuse of girls through interviews conducted with adolescent girls (n = 66) and with caregivers (n = 58) among two conflict-affected populations: villages in South Kivu in the Democratic Republic of the Congo and Sudanese and South Sudanese refugees in Ethiopian camps. The findings suggest how communities use violence as a tool to enforce the importance of girls practicing community-defined "good" adolescent girl behavior, and have implications for gender-based violence programming among other conflict-affected populations. PMID- 29471218 TI - Albumin-covered lipid nanocapsules exhibit enhanced uptake performance by breast tumor cells. AB - Liquid lipid nanocapsules (LLN) represent a promising new generation of drug delivery systems. They can carry hydrophobic drugs in their oily core, but the composition and structure of the surrounding protective shell determine their capacity to survive in the circulatory system and to achieve their goal: penetrate tumor cells. Here, we present a study of LLN covered by the protein human serum albumin (HSA) and loaded with curcumin as a hydrophobic model drug. A cross-linking procedure was performed to further strengthen the protective protein layer. Physicochemical properties and release kinetics of the nanocapsules were investigated, and cellular uptake and killing capacity were evaluated on the human breast-cancer line MCF-7. The nanocapsules exhibited a half maximal inhibitory concentration (IC50) capacity similar to that of free curcumin, but avoiding problems associated with excipients, and displayed an outstanding uptake performance, entering cells massively in less than 1 min. PMID- 29471219 TI - The effects of extrinsic factors on the structural and mechanical properties of Pseudomonas fluorescens biofilms: A combined study of nutrient concentrations and shear conditions. AB - The growth of biofilms on surfaces is a complicated process influenced by several environmental factors such as nutrient availability and fluid shear. In this study, combinations of growth conditions were selected for the study of Pseudomonas fluorescens biofilms including as cultivation time (24- or 48 h), nutrient levels (1:1 or 1:10 King B medium), and shear conditions (75 RPM shaking, 0.4 mL min -1 or 0.7 mL min -1). The use of Confocal Laser Scanning Microscopy (CLSM) determined biofilm structure, while liquid-phase Atomic Force Microscopy (AFM) techniques resolved the mechanical properties of biofilms. Under semi-static conditions, high nutrient environments led to more abundant biofilms with three times higher EPS content compared to biofilms grown under low nutrient conditions. AFM results revealed that biofilms formed under these conditions were less stiff, as shown by their Young's modulus values of 2.35 +/- 0.08 kPa, compared to 4.98 +/- 0.02 kPa for that of biofilms formed under low nutrient conditions. Under dynamic conditions, however, biofilms exposed to low nutrient conditions and high shear rates led to more developed biofilms compared to other tested dynamic conditions. These biofilms were also found to be significantly more adhesive compared to their counterparts grown at higher nutrient conditions. PMID- 29471220 TI - An investigation of konjac glucomannan-keratin hydrogel scaffold loaded with Avena sativa extracts for diabetic wound healing. AB - We have developed a novel hydrogel composed of konjac glucomannan (KGM), human hair proteins (KER), and an ethanolic extract of Avena sativa (OAT) and evaluated its potential as a dressing material for diabetic wounds. KGM is an excellent biocompatible gelling agent that stimulates fibroblast proliferation and immunomodulation. Human hair proteins (KER) are biocompatible, biodegradable, and possess abundant cell adhesion sites. KER also promotes fibroblast attachment and proliferation, keratinocyte migration, and collagen expression, which can accelerate wound healing. OAT consists of oat beta-glucans and several anti inflammatory and antioxidant moieties that can reduce prolonged inflammation in chronic wounds. SEM images confirm the highly porous architecture of the scaffolds. When immersed in PBS, KGM+KER+OAT hydrogels absorb 7.5 times their dry weight. These hydrogels display a measured rate of degradation in lysozyme. KGM+KER+OAT hydrogels showed no significant cytotoxicity against NIH/3T3 fibroblasts. DAPI and SEM images obtained after 48h of cell culture illustrate the attachment and infiltration of fibroblasts. In vivo studies performed using a diabetic rat excision wound model showed that KGM+KER+OAT hydrogels significantly accelerated wound healing compared to the control and the KGM+KER hydrogels.

AB - BACKGROUND: Knowledge about Minimal Important Differences (MIDs) is essential for the interpretation of continuous outcomes, especially patient-reported outcome measures (PROMS). OBJECTIVE: The aim of this study was to estimate the MID for the Western Ontario Rotator Cuff Index (WORC: score 0 (best) to 2100 (worst disability)) in adults with shoulder pain associated with partial-thickness rotator cuff tears, 'symptomatic PTTs', undergoing conservative treatment with physiotherapy. DESIGN: A prospectively-designed anchor-based MID analysis using data from a prospective prognostic study with a three-month follow-up conducted within an outpatient care setting in Germany. METHODS: The MID was estimated using data from 64 adults with atraumatic symptomatic PTTs who underwent three months of conservative treatment with physiotherapy. The anchor was a seven-point Global Perceived Change (GPC) scale. RESULTS: Based on a definition of the MID being the threshold of "being (at least slightly) improved" with a probability nearest to 0.90 (i.e. 9 of 10 patients achieving the MID), the MID for the WORC was estimated as -300 for 'improved' shoulder-related disability in 9 out of 10 patients (95% CI 8 out of 10 patients to everyone) undergoing three months of exercise-based physiotherapy for symptomatic PTTs. CONCLUSIONS: This is the first published MID estimate for the WORC in adults with symptomatic PTTs of the rotator cuff undergoing typical treatment comprising conservative treatment with physiotherapy. The conceptual framework for interpretation facilitates its use in similar clinical contexts. PMID- 29471222 TI - Clinical experience with indigenous kit-based preparation of 68Ga-DOTATOC using commercial 68Ge/68Ga generator. AB - Pharmaceutical grade DOTATOC kits compliant with all the quality control criteria were formulated and radiolabeled with 68Ga in high yields. Comparison with module based 68Ga-DOTATOC established product equivalency. Clinical utility was evaluated in patients with histopathologically confirmed well-differentiated neuroendocrine tumors. Kit-based preparation of 68Ga-DOTATOC could identify sites of primary and metastatic disease. PET/CT images of patients conformed to the established criteria for somatostatin imaging agents and clinical expectations. Results of this study emphasize the potential of kit-based 68Ga-DOTATOC for PET imaging of neuroendocrine tumors. PMID- 29471223 TI - Indirect calculation of monoclonal antibodies in nanoparticles using the radiolabeling process with technetium 99 metastable as primary factor: Alternative methodology for the entrapment efficiency. AB - The use of monoclonal antibodies (Mab) in the current medicine is increasing. Antibody-drug conjugates (ADCs) represents an increasingly and important modality for treating several types of cancer. In this area, the use of Mab associated with nanoparticles is a valuable strategy. However, the methodology used to calculate the Mab entrapment, efficiency and content is extremely expensive. In this study we developed and tested a novel very simple one-step methodology to calculate monoclonal antibody entrapment in mesoporous silica (with magnetic core) nanoparticles using the radiolabeling process as primary methodology. The magnetic core mesoporous silica were successfully developed and characterised. The PXRD analysis at high angles confirmed the presence of magnetic cores in the structures and transmission electron microscopy allowed to determine structures size (58.9 +/- 8.1 nm). From the isotherm curve, a specific surface area of 872 m2/g was estimated along with a pore volume of 0.85 cm3/g and an average pore diameter of 3.15 nm. The radiolabeling process to proceed the indirect determination were well-done. Trastuzumab were successfully labeled (>97%) with Tc-99m generating a clear suspension. Besides, almost all the Tc-99m used (labeling the trastuzumab) remained trapped in the surface of the mesoporous silica for a period as long as 8 h. The indirect methodology demonstrated a high entrapment in magnetic core mesoporous silica surface of Tc-99m-traztuzumab. The results confirmed the potential use from the indirect entrapment efficiency methodology using the radiolabeling process, as a one-step, easy and cheap methodology. PMID- 29471224 TI - Quantification of desoxyrhapontigenin (4-methoxyresveratrol) in rat plasma by LC MS/MS: Application to pre-clinical pharmacokinetic study. AB - Desoxyrhapontigenin (DRG, 4-methoxyresveratrol or trans-3,5-dihydroxy-4' methoxystilbene) is a naturally occurring resveratrol (RES) derivative with a variety of biological activities. To facilitate its further medicinal exploration, a reliable LC-MS/MS method was developed and validated for the quantification of DRG in rat plasma using heavy isotope labelled RES as an internal standard. The ESI was operated in its negative ion mode while DRG and RES were determined by multiple reaction monitoring (MRM) using precursor-to product ion transitions of m/z 241.1 -> 180.8 and m/z 233.0 -> 191.0, respectively. This LC-MS/MS method displayed excellent selectivity, sensitivity (LLOQ = 2.5 ng/ml), accuracy (both intra- and interday mean analytical recovery within 100 +/- 15%) and precision (both intra- and interday CV < 15%). The mean matrix factors were all within 1.000 +/- 0.150 with CV < 15%. The pharmacokinetic profiles of DRG were subsequently examined in Sprague-Dawley rats. Upon intravenous administration (4 or 10 mg/kg), DRG displayed very rapid clearance (Cl = 338 +/- 66 or 275 +/- 30 ml/min/kg) and short mean residence time (MRT = 12.9 +/- 4.7 or 10.4 +/- 0.5 min). After oral administration of DRG fully solubilized by 2-hydroxypropyl-beta-cyclodextrin (HP-beta-CD), the plasma profiles of DRG were highly erratic with a low absolute bioavailability (F < 9.83 +/- 5.31%). When DRG was given at a higher dose (50 mg/kg) in suspension form, the F was increased to 24.1 +/- 5.6%. The pharmacokinetic comparison among DRG, RES and some of its hydroxyl analogues stilbenes was performed. The information obtained from this study will facilitate further exploration on DRG as well as other RES derivatives. PMID- 29471225 TI - Location, location, location: Assessing the spatial patterning between marijuana licenses, alcohol outlets and neighborhood characteristics within Washington state. AB - BACKGROUND: The availability of marijuana products is becoming increasingly prevalent across the United States (US), many states are allowing for the production, processing, and retailing of these products for medical and/or recreational use. The purpose of this study is to: (1) examine the spatial patterning of marijuana licenses, and (2) examine the impact of alcohol outlets in addition to other neighborhood characteristics on marijuana licenses within the state of Washington. METHODS: This cross-sectional observational study examined 1458 census tracts in Washington state from 2017, using marijuana and alcohol data from the Washington State Liquor and Cannabis Board as well as neighborhood characteristics data from the American Community Survey 2011-2015 5 year estimates. We used exploratory and formal spatial regression methods, including integrated nested Laplace approximation within a Bayesian statistical framework, to address the study aims. RESULTS: Our results indicate there is significant spatial patterning of marijuana producers and processors across the state. We also found that all marijuana licenses are located in poorer census tracts, and marijuana retailers are co-located in census tracts with off-premises alcohol outlets. CONCLUSIONS: Our study provides empirical evidence of the relationship between marijuana licenses, alcohol outlets, and neighborhood characteristics, and has important implications for policymakers in other states currently considering legalizing marijuana-products for medical and/or recreational use. PMID- 29471226 TI - Examining effects of medical cannabis narratives on beliefs, attitudes, and intentions related to recreational cannabis: A web-based randomized experiment. AB - BACKGROUND: This experimental study tests effects of exposure to video narratives about successful symptom relief with Medical Cannabis (MC) on attitudes, beliefs, and intentions related to recreational cannabis use. METHODS: Patient video testimonials were modeled after those found in extant media coverage. Israeli participants (N = 396) recruited through an online survey company were randomly assigned to view a narrative or a non-narrative video containing equivalent information about MC. Video content was further manipulated based on whether the protagonist had a stigmatized disease or not, and whether attribution of responsibility for his disease was internal or external. RESULTS: Exposure to patient testimonials indirectly increased positive attitudes, beliefs and intentions related to recreational cannabis use through changing attitudes, beliefs and intentions related to MC. Furthermore, exposure to narratives in which the patient was presented as not to blame for contracting his illness (external attribution) was associated with more positive attitudes, beliefs and intentions toward MC, a factor that was significantly associated with more positive attitudes, beliefs and intentions related to recreational cannabis use. CONCLUSIONS: These results suggest that narrative news media coverage of MC may influence public attitudes toward recreational cannabis. Because such media stories continue to be commonplace, it is important to examine potential spillover effects of this coverage on public perceptions of recreational cannabis. Cannabis prevention programs should address the role of media coverage in shaping public opinion and address the distinction between medical and recreational cannabis use. PMID- 29471227 TI - The impact of acute and short-term methamphetamine abstinence on brain metabolites: A proton magnetic resonance spectroscopy chemical shift imaging study. AB - BACKGROUND: Abuse of methamphetamine (MA) is a global health concern. Previous 1H MRS studies have found that, with methamphetamine abstinence (MAA), there are changes in n-acetyl-aspartate (NAA/Cr), myo-inositol (mI/Cr), choline (Cho/Cr and Cho/NAA), and glutamate with glutamine (Glx) metabolites. Limited studies have investigated the effect of acute MAA, and acute-to-short-term MAA on brain metabolites. METHODS: Adults with chronic MA dependence (n = 31) and healthy controls (n = 22) were recruited. Two-dimensional chemical shift 1H-MRS imaging (TR2000 ms, TE30 ms) slice was performed and included voxels in bilateral anterior-cingulate (ACC), frontal-white-matter (FWM), and dorsolateral-prefrontal cortices (DLPFC). Control participants were scanned once. The MA group was scanned twice, with acute (1.5 +/- 0.6 weeks, n = 31) and short-term MAA (5.1 +/- 0.8 weeks, n = 22). The change in 1H-MRS metabolites over time (n = 19) was also investigated. Standard 1H-MRS metabolites are reported relative to Cr + PCr. RESULTS: Acute MAA showed lower n-acetyl-aspartate (NAA) and n-acetyl-aspartate with n-acetyl-aspartyl-glutamate (NAA + NAAG) in left DLPFC, and glycerophosphocholine with phosphocholine (GPC + PCh) in left FWM. Short-term MAA showed lower NAA + NAAG and higher myo-inositol (mI) in right ACC, lower NAA and NAA + NAAG in the left DLPFC, and lower GPC + PCh in left FWM. Over time, MAA showed decreased NAA and NAA + NAAG and increased mI in right ACC, decreased NAA and NAA + NAAG in right FWM, and decreased in mI in left FWM. CONCLUSION: In acute MAA, there was damage to the integrity of neuronal tissue, which was enhanced with short-term MAA. From acute to short-term MAA, activation of neuroinflammatory processes are suggested. This is the first 1H-MRS study to report the development of neuroinflammation with loss of neuronal integrity in MAA. PMID- 29471228 TI - Correlates and trends in youth co-use of marijuana and tobacco in the United States, 2005-2014. AB - BACKGROUND: Past-month marijuana and tobacco use (co-use) are increasing among U.S. adults, but little is known about the prevalence of co-use among U.S. youth. This study uses nationally representative data to assess the prevalence, correlates, and trends in co-use of marijuana and tobacco, tobacco-only use, and marijuana-only use among U.S. youth. METHODS: Data came from 176,245 youth ages 12-17 who responded to the National Survey on Drug Use and Health - a nationally representative, household interview survey - between 2005 and 2014. Prevalence, demographics and substance use characteristics from 2013 to 14 were assessed across three groups: past-month users of marijuana and tobacco (co-users), past month tobacco-only users, and past-month marijuana-only users. Multinomial logistic regression was used to assess demographic correlates of each group. Linear and quadratic trends were assessed from 2005 to 2014 using logistic regression with orthogonal polynomials. RESULTS: In 2013-14, 5.4% of youth reported past-month co-use of tobacco and marijuana, 2.2% reported marijuana-only use, and 3.9% reported tobacco-only use. Co-use was associated with higher prevalence of past year marijuana dependence (vs. marijuana-only users), and higher past-month risky alcohol and other illicit drug use (vs. both tobacco and marijuana-only use groups). Co-use did not increase significantly between 2005 and 2014; tobacco-only use declined, and marijuana-only use increased. CONCLUSIONS: Co-use of marijuana and tobacco is more prevalent than tobacco-only or marijuana-only use in U.S. youth. Given changing tobacco and marijuana policies, ongoing surveillance and studies that seek to increase our understanding of co-use behaviors in youth are critical. PMID- 29471229 TI - Impacts of biochar on the environmental risk of antibiotic resistance genes and mobile genetic elements during anaerobic digestion of cattle farm wastewater. AB - Biochar has positive effects on nitrogen conservation during anaerobic digestion, but its impacts on antibiotic resistance genes (ARGs) are unclear. Therefore, the effect of biochar (0, 5, 20, and 50 g/L) on the environmental risk of ARGs during cattle manure wastewater anaerobic digestion were investigated. The results showed that 5 g/L biochar reduced the relative abundances (RAs) of 5/13 ARGs while 20 g/L biochar significantly reduced the total RAs of ARGs in the digestion products, where the RA of ISCR1 was 0.89 log lower than the control. Biochar mainly affected the distribution of ARGs by influencing the RAs of Firmicutes and Proteobacteria, and the influence of 20 g/L biochar was greater than that of 5 g/L. Mobile genetic elements also influenced the ARG profiles, especially intI2 and ISCR1. The addition of 20 g/L biochar to cattle farm wastewater anaerobic digestion systems could reduce the environmental risk of ARGs. PMID- 29471230 TI - Variations of floc morphology and extracellular organic matters (EOM) in relation to floc filterability under algae flocculation harvesting using polymeric titanium coagulants (PTCs). AB - The work evaluated the algae cells removal efficiency using titanium salt coagulants with different degree of polymerization (PTCs), and the algae cells aggregates and extracellular organic matter (EOM) under chemical flocculation were investigated. The results indicated that PTCs performed well in algae cells flocculation and separation. The main mechanism using PTCs of low alkalisation degree for algae flocculation was associated with charge neutralization, while adsorption bridging and sweep flocculation was mainly responsible for algae removal by PTCs of high alkalisation degree treatment. In addition, the flocs formed by PTC1.0 showed the best filtration property, and EOM reached the minimum at this time, indicating the flocs formed by PTC1.0 were more compact than other PTCs, which can be confirmed by SEM analysis. Three-dimensional excitation emission matrix fluorescence (3D-EEM) and high performance size exclusion chromatography (HPSEC) revealed that the EOMs were removed under PTCs flocculation, which improved floc filterability.

AB - Pulping wastewater still contains massive refractory organics after biotreatment, with high colority, low biodegradability, and lasting biotoxicity. To eliminate refractory organics in pulping wastewater, a methanotrophic co-metabolic system in a gas cycle Sequencing Batch Biofilm Reactor (gcSBBR) seeded by soil at a ventilation opening of coal mine was quickly built on the 92nd day. The removal rate of COD, colority and TOC was 53.28%, 50.59% and 51.60%, respectively. Analysis of 3D-EEM indicated that glycolated protein-like, melanoidin-like or lignocellulose-like, and humic acid-like decreased by 7.85%, 5.02% and 1.74%, respectively. Moreover, this system exhibited high activity of soluble methane monooxygenase (sMMO) and mmoX encoding sMMO reached up to 7.89 * 105 copies/MUL. Methanotrophs, namely, Methylocaldum (8.28%), Methylococcus (6.06%) and Methylomonas (0.07%), were detected by 16S rRNA sequencing. And other bacteria were dominated by Denitratisoma, Anaerolineaceae_uncultured and Methylophilaceae_uncultured. Refractory organics was biodegraded through the synergy among microorganisms, and a postulated synergy pathway was put forward. PMID- 29471232 TI - Changes in pro-inflammatory cytokine levels and late-life depression: A two year population based longitudinal study. AB - Longitudinal associations of cytokine levels with depression are unclear. This study aimed to investigate cross-sectional and prospective associations between five serum pro-inflammatory cytokine levels and late-life depression. 732 Korean people aged 65+ were evaluated at baseline. Of 631 without depression (Geriatric Mental State schedule) at baseline, 521 (83%) were followed over a 2 year period and incident depression was ascertained. Serum tumor necrosis factor-alpha, interleukin (IL)-1alpha, IL-1beta, IL-6, and IL-8 levels were assayed at both baseline and follow-up. Associations between cytokine levels and depressive status were evaluated using linear regression models, considering potential covariates (demographics, cognitive function, disability, lifestyle factors, and vascular risk factors) and applying Bonferroni corrections. Prevalent depression at baseline was significantly associated with higher contemporaneous levels of IL 1beta and IL-8, independent of relevant covariates and after applying Bonferroni corrections. In the analyses of the five cytokine levels in combination, independent associations were found between prevalent depression and increased numbers of cytokines at higher levels at baseline. Incident depression was significantly associated with increases in IL-1beta, IL-6, and IL-8 levels during the follow-up independent of relevant covariates and after applying Bonferroni corrections. In combination analyses, incident depression was independently associated with higher numbers of cytokines showing increasing levels over the same follow-up period. However, incident depression was not predicted by higher baseline pro-inflammatory cytokine levels in any analysis. Our findings suggest that depression might affect serum cytokines alterations and lead to inflammatory processes in late-life.

AB - The structural forms of water/deuterated water molecules located on the surface of borosilicate capillaries have been first investigated in this study on the basis of the Raman spectral data obtained at different temperatures and under atmospheric pressure for molecules in bulk and also for molecules absorbed by borosilicate glass surface. The strongest two fundamental bands locating at 3063cm-1 (2438cm-1) in the recorded Raman spectra are assigned here to the OH (OD) bond stretching vibrations and they are compared with the corresponding bands observed at 3124cm-1 (2325cm-1) in the Raman spectrum of ice Ih. Our spectroscopic observations have indicated that the structure of water and deuterated water molecules on borosilicate surface is similar to that of ice Ih (hexagonal phase of ice). These observations have also indicated that water molecules locate on the borosilicate surface so as to construct a bilayer structure and that strong and weak intermolecular hydrogen bonds are formed between water/deuterated molecules and silanol groups on borosilicate surface. In accordance with these findings, water and deuterated water molecules at the interface of capillary have a higher melting temperature. PMID- 29471234 TI - Influences of motorcycle rider and driver characteristics and road environment on red light running behavior at signalized intersections. AB - In Thailand, red light running is considered as one of the most dangerous behaviors at intersection. Red light running (RLR) behavior is the failure to obey the traffic control signal. However, motorcycle riders and car drivers who are running through red lights could be influenced by human factors or road environment at intersection. RLR could be advertent or inadvertent behavior influenced by many factors. Little research study has been done to evaluate the contributing factors influencing the red-light violation behavior. This study aims to determine the factors influencing the red light running behavior including human characteristics, physical condition of intersection, traffic signal operation, and traffic condition. A total of 92 intersections were observed in Chiang Mai, Nakhon Ratchasima, and Chonburi, the major provinces in each region of Thailand. In addition, the socio-economic characteristics of red light runners were obtained from self-reported questionnaire survey. The Binary Logistic Regression and the Multiple Linear Regression models were used to determine the characteristics of red light runners and the factors influencing rates of red light running respectively. The results from this study can help to understand the characteristics of red light runners and factors affecting them to run red lights. For motorcycle riders and car drivers, age, gender, occupation, driving license, helmet/seatbelt use, and the probability to be penalized when running the red light significantly affect RLR behavior. In addition, the results indicated that vehicle travelling direction, time of day, existence of turning lane, number of lanes, lane width, intersection sight distance, type of traffic signal pole, type of traffic signal operation, length of yellow time interval, approaching speed, distance from intersection warning sign to stop line, and pavement roughness significantly affect RLR rates. PMID- 29471235 TI - Competition between heavy metal ions for binding sites in lichens: Implications for biomonitoring studies. AB - The competitive behavior of divalent heavy metals (Cd, Cr, Pb, Zn) during cation uptake was investigated in the foliose lichen Xanthoria parietina. Lichen thalli were incubated with solutions containing 10 and 100 MUM of CdCl2, CuCl2, and ZnCl2 as well as 5 and 50 MUM of Pb(NO3)2, tested individually and in combination (Cd2++Cu2++Pb2++Zn2+). The analysis of molar concentrations suggests that a competition between cations for binding sites in X. parietina does exist. The decrease in net uptake between single and mixed solutions ranged between 14 and 29% at the lowest concentration and between 38 and 68% at the highest concentration. Furthermore, the uptake was proportionally lower for richer solutions. Each metal may behave differently when uptook: some (toxic elements) are preferentially stored at extracellular level (Cd, Pb), while others (micro nutrients) are also present at intracellular level (Cu and Zn). The proportion between extracellular and total content changed for those elements accumulated also at intracellular level (Cu and Zn), while for Cd and Pb almost all the uptake occurred by passive mechanisms mainly at extracellular binding sites. The competition between metals for binding sites in the lichen surface entails that bioaccumulation data might result in an underestimation of some element levels measured in biomonitoring studies. PMID- 29471236 TI - Shifts of system performance and microbial community structure in a constructed wetland after exposing silver nanoparticles. AB - The increasing utilization of silver nanoparticles (Ag NPs) in industry and commerce inevitably raises its release into wastewater. In this work, effects of Ag NPs on system performance and microbial community along the way of a vertical flow constructed wetland (VFCW) were investigated, along with the removal and fate of Ag NPs within the system. Results showed that the performance of control wetland kept stable during the experimental period, and the top substrate layer (soil layer) of wetland could remove most of pollutants in the influent. The study also suggested that addition of Ag NPs did not significantly affect organic matters removal. However, adverse effects were observed on the nitrogen and phosphorus removal. Removal efficiencies of TN, NH4+-N and TP approximately obviously reduced by approximately 10.10%, 8.42% and 28.35% respectively in contrast to before dosing after exposing 100 MUg/L Ag NPs for 94 d, while the no dosing wetland with the stable performance. It was found that Ag NPs accumulated in the upper soil layer more than in the lower soil layer, and Ag NPs could enter into the plant tissues. After continuous input of Ag NPs, removal efficiency of Ag NPs was measured as 95.72%, which showed that the CW could effectively remove Ag NPs from the wastewater. The high-throughput sequencing results revealed that Ag NPs caused the shifts in microbial community structures and changed the relative abundances of key functional bacteria, which finally resulted in a lower efficiency of biological nitrogen and phosphorus removal. PMID- 29471237 TI - Quantifying the harmful potential of ten essential oils on immature Trichogramma pretiosum stages. AB - The use of chemical insecticides and non-selective natural products authorized for use in organic farming may reduce the effectiveness of egg parasitoids. The side-effects of ten plant essential oils on immature stages of Trichogramma pretiosum were evaluated. Carapa guianensis, Origanum vulgare and Zingiber officinalle during the F1 generation, and Azadirachtin and Mentha piperita in the F2 generation were slightly harmful (class II: 30-79%) to the emergence of this parasitoid. All essential oils affected the longevity of females of the F1 and F2 generations. Thymus vulgaris and Z. officinalle were the oils most harmful to female longevity. Carapa guianensis proved slightly harmful (class II: 30-79%) to parasitism in the F1 generation when applied during the egg-larval and pre-pupal stages and O. vulgare in the F1 generation in the pre-pupal stage alone, of this parasitoid. The sex ratio was lower than 0.5 during the pre-pupal stage of the F1 generation with Azadirachtin, C. guianensis, O. vulgare, Piper nigrum and Syzigium aromaticum, but this parameter was not affected for the other biological stages of T. pretiosum in the F1 and F2 generations. The Azadirachtin, C. guianensis, M. piperita, O. vulgare, T. vulgaris and Z. officinalle oils revealed a mild toxic effect to the immature stages of T. pretiosum and, therefore, it should be used according to patterns of ecological selectivity. Allium sativum and Citrus sinensis essential oils were not harmful to T. pretiosum, and can be used in Integrated Pest Management. PMID- 29471238 TI - Prediction of soil urea conversion and quantification of the importance degrees of influencing factors through a new combinatorial model based on cluster method and artificial neural network. AB - Quantitative prediction of soil urea conversion is crucial in determining the mechanism of nitrogen transformation and understanding the dynamics of soil nutrients. This study aimed to establish a combinatorial prediction model (MCA-F ANN) for soil urea conversion and quantify the relative importance degrees (RIDs) of influencing factors with the MCA-F-ANN method. Data samples were obtained from laboratory culture experiments, and soil nitrogen content and physicochemical properties were measured every other day. Results showed that when MCA-F-ANN was used, the mean-absolute-percent error values of NH4+-N, NO3--N, and NH3 contents were 3.180%, 2.756%, and 3.656%, respectively. MCA-F-ANN predicted urea transformation under multi-factor coupling conditions more accurately than traditional models did. The RIDs of reaction time (RT), electrical conductivity (EC), temperature (T), pH, nitrogen application rate (F), and moisture content (W) were 32.2%-36.5%, 24.0%-28.9%, 12.8%-15.2%, 9.8%-12.5%, 7.8%-11.0%, and 3.5% 6.0%, respectively. The RIDs of the influencing factors in a descending order showed the pattern RT > EC > T > pH > F > W. RT and EC were the key factors in the urea conversion process. The prediction accuracy of urea transformation process was improved, and the RIDs of the influencing factors were quantified. PMID- 29471239 TI - Identification of miR-200c-3p as a major regulator of SaoS2 cells activation induced by fluoride. AB - The skeletal lesion of fluoride has become a major concern in many countries due to its damage to bone and joints and even leading to disability. Skeletal fluorosis is characterized by disturbance of bone metabolism, aberrant proliferation and activation of osteoblasts is critical for the pathogenesis. However, the mechanism underlying the osteotoxicity of fluoride has not been clearly illustrated and there is still limited information on the role of miRNAs in skeletal fluorosis. In this study, we found that NaF promoted SaoS2 proliferation and activation by activating BMP4/Smad pathway. NaF increased expression of miR-200c-3p and miR-200c-3p inhibitor reduced activation of SaoS2 induced by NaF via targeting Noggin to repress BMP4/Smad. These findings suggested an important regulatory role of miR-200c-3p on BMP4/Smad pathway during skeletal fluorosis. MiR-200c-3p might be a novel therapeutic target for skeletal fluorosis. PMID- 29471240 TI - A multiregional survey of nickel in outdoor air particulate matter in China: Implication for human exposure. AB - Nickel is a widespread environmental contaminant, and it is toxic to humans in certain forms at high doses. Despite this, nationwide data on nickel in outdoor air particulate matter and human exposure to nickel through inhalation in China are limited. In the present study, 662 outdoor air samples from seven representative provinces such as Shanghai, Hubei, Hunan, Hebei, Guangdong, Yunnan, and Shanxi were collected between March 2013 and February 2014 and analyzed by inductively coupled plasma mass spectrometry. The concentrations of nickel in the air were in the range of 2.1-80.9 ng/m3 (geometric mean: 14.4 ng/m3). In most areas, the concentrations of nickel were higher in winter and spring than those measured in summer and autumn. The daily intake (median) of nickel through inhalation of air particulate matter was estimated. Although the nickel concentrations in some air samples were high, inhalation of the air particulate matter accounted for a minor part of the total nickel intake; however, the adverse effects of human exposure to nickel through inhalation and its potential sources require more attention, particularly in Shanghai. This is a multiregional survey of nickel in outdoor air particulate matter in China. PMID- 29471241 TI - Influence of chelation on the Fenton-based electrochemical degradation of herbicide tebuthiuron. AB - This study describes the performance of electro-Fenton (EF) and photoelectro Fenton (PEF) processes to degrade the herbicide tebuthiuron (TBH) in 0.050 M Na2SO4 at pH = 3.0. Experiments were performed in an undivided cell equipped with a boron-doped diamond (BDD) or Pt anode and an air-diffusion cathode that produces H2O2. Physisorbed hydroxyl radicals (M(OH)) generated from water oxidation at the anode and/or free OH formed from Fenton's reaction acted as main oxidants. All processes became much more effective using a BDD anode because of the higher oxidation power of BDD(OH). Sulfate and nitrate were the predominant ions released during TBH destruction. In both, EF and PEF treatments, two distinct kinetic regimes were observed, the first one corresponding to the oxidation of free TBH by OH and the second one to that of the Fe(III)-TBH complex by M(OH). The effect of Fe2+ and TBH concentrations on the kinetics of both regions has been examined. Moreover, a poor mineralization was reached with Pt anode, whereas almost total mineralization was attained by EF and PEF with BDD. Both processes showed analogous mineralization rates because the intermediates produced could not be photodegraded by UVA light. Gas chromatography-mass spectrometry analysis of electrolyzed solutions revealed the generation of eight heteroaromatics along with 1,3-dimethylurea, which have been included in a reaction pathway proposed for the initial degradation of TBH. PMID- 29471242 TI - Development of a glucose sensor employing quick and easy modification method with mediator for altering electron acceptor preference. AB - Enzyme based electrochemical biosensors are divided into three generations according to their type of electron transfer from the cofactors of the enzymes to the electrodes. Although the 3rd generation sensors using direct electron transfer (DET) type enzymes are ideal, the number of enzyme types which possess DET ability is limited. In this study, we report of a glucose sensor using mediator-modified glucose dehydrogenase (GDH), that was fabricated by a new quick and-easy method using the pre-functionalized amine reactive phenazine ethosulfate (arPES). Thus mediator-modified GDH obtained the ability to transfer electrons to bulky electron acceptors as well as electrodes. The concentration of glucose was successfully measured using electrodes with immobilized PES-modified GDH, without addition of external electron mediators. Therefore, continuous monitoring systems can be developed based on this "2.5th generation" electron transfer principle utilizing quasi-DET. Furthermore, we successfully modified two other diagnostically relevant enzymes, glucoside 3-dehydrogenase and lactate oxidase, with PES. Therefore, various kinds of diagnostic enzymes can achieve quasi-DET ability simply by modification with arPES, suggesting that continuous monitoring systems based on the 2.5th generation principle can be developed for various target molecules. PMID- 29471243 TI - TRPS1 Suppresses Breast Cancer Epithelial-mesenchymal Transition Program as a Negative Regulator of SUZ12. AB - Breast cancer (BC) is among the most common malignant diseases and metastasis is the handcuff of treatment. Cancer metastasis is a multistep process associated with the epithelial-mesenchymal transition (EMT) program. Several studies have demonstrated that transcriptional repressor GATA binding 1 (TRPS1) played important roles in development and progression of primary BC. In this study we sought to identify the mechanisms responsible for this function of TRPS1 in the continuum of the metastatic cascade. Here we described that TRPS1 was significantly associated with BC metastasis using public assessable datasets. Clinically, loss of TRPS1 expression in BC was related to higher histological grade. In vitro functional study and bioinformatics analysis revealed that TRPS1 inhibited cell migration and EMT in BC. Importantly, we identified SUZ12 as a novel target of TRPS1 related to EMT program. ChIP assay demonstrated TRPS1 directly inhibited SUZ12 transcription by binding to the SUZ12 promoter. Loss of TRPS1 resulted in increased SUZ12 binding and H3K27 tri-methylation at the CDH1 promoter and repression of E-cadherin. In all, our data indicated that TRPS1 maintained the expression of E-cadherin by inhibiting SUZ12, which might provide novel insight into how loss of TRPS1 contributed to BC progression. PMID- 29471244 TI - Two sesquiterpene aminoquinones protect against oxidative injury in HaCaT keratinocytes via activation of AMPKalpha/ERK-Nrf2/ARE/HO-1 signaling. AB - AIMS: To investigate the cytoprotective effects of two sesquiterpene aminoquinones isolated from the marine sponge Dysidea fragilis, Dysidaminone H (DA8) and 3'-methylamino-avarone (DA14), we examined their effects against hydrogen peroxide (H2O2)-induced oxidative injury in human keratinocyte cell line and elucidated the underlying mechanisms. MAIN METHODS: Cell viability was detected using a CCK-8 assay kit. Intracellular reactive oxygen species (ROS) production was measured by fluorescence of 2, 7-Dichlorodi-hydrofluorescein diacetate (DCFH-DA). Messenger RNA and protein expression were measured by real time quantitative PCR and western blotting analysis. Immunocytochemistry was performed to determine the intracellular location of nuclear factorerythroid 2 p45 related factor 2 (Nrf2). The antioxidant response element (ARE)-luciferase reporter gene assay and RNA interference were used to establish the role of ARE and Nrf2. KEY FINDINGS: DA8 and DA14 (DAs) resisted H2O2induced decline of cell viability by inhibiting the accumulation of ROS. Meanwhile, DAs increased HO-1 expression and ARE activity and induced Nrf2 expression, as well as the accumulation of Nrf2 in the cell nucleus. However, silencing of Nrf2 abolished DAs-induced HO-1 expression and ARE luciferase activation. In addition, DAs induced the phosphorylation of both cyclic AMP-activated protein kinase-alpha (AMPKalpha) and extracellular signal-regulated kinase (ERK), while specific inhibitors of AMPKalpha and ERK abrogated HO1 upregulation and Nrf2 activation. SIGNIFICANCE: DAs provided cytoprotective effects against H2O2-induced cytotoxicity by activation of the Nrf2/ARE/HO-1 pathway via phosphorylation of AMPKalpha and ERK. The findings suggested that DA8 and DA14 might be the candidate therapeutic agents for skin diseases caused by oxidative injury. PMID- 29471245 TI - Intraperitoneal administration of mesenchymal stem cells ameliorates acute dextran sulfate sodium-induced colitis by suppressing dendritic cells. AB - Dendritic cells (DCs) have important pathogenic role in the induction and progression of ulcerative colitis (UC), but their role in mesenchymal stem cells (MSCs)-mediated suppression of colon injury and inflammation is not revealed. By using dextran sodium sulfate (DSS)-induced colitis, a well-established murine model of UC, we examined effects of MSCs on phenotype and function of colon infiltrating DCs. Clinical, histological, immunophenotypic analysis and passive transfer of MSCs-primed DCs were used to evaluate capacity of MSC to suppress inflammatory phenotype of DCs in vivo. Additionally, DCs:MSCs interplay was also investigated in vitro, to confirmed in vivo obtained findings. Intraperitoneally administered MSCs (2 * 106) significantly reduced progression of DSS-induced colitis and reduced serum levels of inflammatory cytokines (IL-1beta, IL-12, and IL-6). Passive transfer of in vivo MSCs-primed DCs reduced severity of colitis while passive transfer of MSCs-non-primed DCs aggravated DSS-induced colitis. Through the secretion of immunomodulatory Galectin 3, MSCs, in paracrine manner, down-regulated production of inflammatory cytokines in DCs and attenuated expression of co-stimulatory and major histocompatibility complex class II molecules on their membranes. Taken together, these results indicate that MSCs achieved their beneficial effects in DSS-induced colitis by suppressing inflammatory phenotype of DCs in Gal-3 dependent manner. Therapeutic targeting of DCs by MSCs should be explored in future studies as a useful approach for the treatment of UC. PMID- 29471246 TI - Effects of sunitinib targeted chemotherapy on the osseointegration of titanium implants. AB - Targeted chemotherapies are novel therapeutic approaches for many malignancies. In contrast to conventional chemotherapies, which are given for a predetermined duration, treatment with targeted chemotherapies like sunitinib is routinely continuous over longer periods, sometimes years. During this prolonged treatment period, patients may need to restore their missing teeth with dental implants. The aim of this study was to examine the effect of the anti-angiogenic substance sunitinib targeted chemotherapy on the osseointegration of titanium implants in a rabbit model. Fourteen white New Zealand rabbits were randomly assigned to two groups of either oral sunitinib at 10 mg/kg twice per week dose for 4 weeks (n = 7) or placebo (n = 7). The first dose was given 2 days before the surgical intervention. Each rabbit received one titanium dental implant in the right distal femoral condyle. Four weeks following implant insertion, rabbits were sacrificed and bone specimens containing the implants were retrieved. Osseointegration of the implants was analyzed using micro-computed tomography and histomorphometric evaluation. Both micro-computed tomography and histomorphometric analysis showed that the osseointegration parameters, including the ratio of bone volume to total volume and bone-implant contact percent for the sunitinib group were significantly lower than those in the control group (P <= 0.05). Sunitinib targeted chemotherapy had a negative effect on the osseointegration of titanium implants inserted in a rabbit model. PMID- 29471247 TI - Family functioning and adolescent internalizing symptoms: A latent profile analysis. AB - This study aimed to characterize adolescent family functioning typologies using latent profile analysis (LPA). A secondary aim was to examine profile associations with adolescent internalizing symptoms at one-year follow-up. Students (N = 1029; 53% female; mean age = 16.14, SD = .75 years) completed measures of family functioning, anxiety, and depressive symptoms at two time points. LPA was conducted to characterize family functioning typologies at Time 1, revealing five profiles: 1) Low Family Functioning, 2) Only Close to Father, 3) Average Family Functioning, 4) Only Close to Mother, and 5) High Family Functioning. Results indicated that the Low and Only Close to Mother profiles had greater depressive symptoms at Time 2, compared with the Average profile. The High profile had fewer depressive symptoms at Time 2. The Low and Only Close to Mother profiles also had significantly more anxiety symptoms at Time 2. Findings highlight the utility of examining family functioning profiles. PMID- 29471248 TI - Using structured light three-dimensional surface scanning on living individuals: Key considerations and best practice for forensic medicine. AB - Non-contact three-dimensional (3D) surface scanning methods have been applied to forensic medicine to record injuries and to mitigate ordinary photography shortcoming. However, there are no literature concerning practical guidance for 3D surface scanning of live victims. This paper aimed to investigate key 3D scanning issues of the live body to develop a series of scanning principles for future use on injured victims. The Pico Scan 3D surface scanner was used on live test subjects. The work focused on analysing the following concerns: (1) an appropriate 3D scanning technique to scan different body areas, (2) the ideal number of scans, (3) scanning approaches to access various areas of the body and (4) elimination of environmental background noise in the acquired data. Results showed that scanning only a required surface of the body area in the stable manner was more efficient when compared to complete 360 degrees -scanning; therefore, it used as a standard 3D scanning technique. More than three scans were sufficient when trying to obtain an optimal wireframe mode presentation of the result. Three different approaches were suggested to provide access to the various areas of the body. Undertaking scanning using a black background eliminated the background noise. The work demonstrated that the scanner will be promising to reconstruct injuries from different body areas, although the 3D scanning of the live subjects faced some challenges. PMID- 29471249 TI - Post-mortem biochemistry of NSE and S100B: A supplemental tool for detecting a lethal traumatic brain injury? AB - PURPOSE: Traumatic brain injury (TBI) is a very common entity that leads to numerous fatalities all over the world. Therefore, forensic pathologists are in desperate need of supplemental methodological tools for the diagnosis of TBI in everyday practice besides the standard autopsy. The present study determined post mortem neuron specific enolase (NSE) and S100 calcium-binding protein B (S100B) levels as biological markers of an underlying TBI in autopsy cases. METHODS: Paired serum and CSF samples of 92 fatalities were collected throughout routine autopsies. Afterwards, the marker levels were assessed using commercially available immunoassays (ECLIA, Roche Diagnostics). For statistical analysis, we compared the TBI cases to three control groups (sudden natural death by acute myocardial infarction, traumatic death without impact on the head, cerebral hypoxia). Moreover, the TBI cases were subdivided according to their survival time of the trauma. Brain specimens have been collected and stained immunohistochemically against the aforementioned proteins to illustrate their typical cellular staining patterns with an underlying TBI compared to non-TBI fatalities. PRINCIPAL RESULTS: CSF NSE and S100B levels were elevated after TBI compared to all control groups (p < 0.001). Although this finding can already be investigated among the TBI cases dying immediately subsequent to the trauma, the marker levels in CSF increase with longer survival times until a peak level within the first three days after trauma. There is a strong correlation between both marker levels in CSF (r = 0.67). The presence or absence of cerebral tissue contusion following the initial trauma does not seem to affect the CSF levels of both proteins (p > 0.05). Post-mortem serum levels of both proteins were not elevated in TBI cases compared to controls (p > 0.05). Former elaborated cut-off values in CSF were confirmed and were only exceeded when a TBI survival time of at least 30 min was reached. MAJOR CONCLUSIONS: The present results report that post-mortem NSE and S100B CSF levels are significantly elevated subsequent to a fatal TBI. PMID- 29471250 TI - Duret haemorrhage: An unusual finding in compression of neck structures. AB - Hanging is one of the most lethal methods of suicide, where survival is an obvious rarity. Those who survive the initial act of hanging mostly suffer from hypoxic ischemic encephalopathy, and show some form of neurological damage. Intracranial haemorrhages are rarely associated with hanging. We report the first case of Duret haemorrhages in a 58 years old victim who survived for 8 days after the attempted hanging. Duret haemorrhage is mostly associated with fatal outcome. It is thus implied that cerebral edema should be brought under control at the earliest to prevent transtentorial herniation and subsequent Duret haemorrhages. PMID- 29471251 TI - Adopting data interpretation on mining fine-grained near-repeat patterns in crimes. AB - The near-repeat effect is a well-known phenomenon in crime analysis. The classic research methods focus on two aspects. One is the geographical factor, which indicates the influence of a certain crime risk on other similar crime incidents in nearby places. The other is the social network, which demonstrates the contacts of the offenders and explain "near" as degrees instead of geographic distances. In our work, these coarse-grained patterns discovering methods are summarized as bundled-clues techniques. In this paper, we propose a knotted-clues method. Adopting a data science perspective, we make use of a data interpretative technology and discover that the near-repeat effect is not always so near in geographic or network structure. With this approach, we analyze the near-repeat patterns in all districts of the dataset, as well as in different crime types. Using open source data from Crimes in Chicago provided by Chicago Police Department, we find interesting relationships and patterns with our mining method, which have a positive effect on police deployment and decision making. PMID- 29471252 TI - Relationship between monocytes to lymphocytes ratio and axial spondyloarthritis. AB - BACKGROUND: Axial spondyloarthritis (axSpA) is a progressive, chronic, inflammatory skeletal disorder affecting the spine and sacroiliac joints. Many studies have shown that neutrophils, lymphocytes, monocytes, platelets, and red blood cells (RBCs) play important roles in the inflammatory process of axSpA. Neutrophils to lymphocytes ratio (NLR) and red blood cell distribution width (RDW) have been reported to be simple and inexpensive markers to indicate the disease activity of axSpA. However, the role of monocytes to lymphocytes ratio (MLR) and platelets to lymphocytes ratio (PLR) in axSpA was rarely mentioned. OBJECTIVE: The study's aim was to determine the role of MLR and PLR in axSpA patients and to investigate their relationships with disease severity. METHODS: AxSpA patients who fulfilled the Assessment in Ankylosing Spondylitis International Society classification criteria published in 2009 were enrolled in this study and divided into nonradiographic axial spondyloarthritis (nr-axSpA) group and ankylosing spondylitis (AS) group. Healthy age and gender-matched subjects were also enrolled as control group. MLR, PLR, NLR, RDW, C-reactive protein (CRP) level, and erythrocyte sedimentation rate (ESR) level were assessed. The correlation between the variables with finger-to-floor distance, Modified Schober test, and occiput-to-wall distance were tested with Pearson correlation. Furthermore, area under curve (AUC) value, sensitivity, specificity, and the optimal cutoff values were determined using receiver operating characteristic (ROC) curves. RESULTS: A total of 148 axSpA patients (67 nr-axSpA patients and 81 AS patients) and 58 healthy subjects were included in the study. The MLR, NLR, PLR, and RDW in axSpA group were higher than those in the control group (P < 0.05). Among them, MLR and RDW were highly increased in AS group compared with the nr-axSpA group (P < 0.05). MLR, NLR, PLR, and RDW were all positively correlated with ESR level and CRP level (P < 0.05). MLR and RDW were positively correlated with finger-to-floor distance and negatively correlated with Modified Schober test (P < 0.05). RDW was positively correlated with occiput to-wall distance (P < 0.05). ROC curve results showed MLR yielded a higher AUC than NLR, PLR, and RDW (P < 0.05). In addition, the optimal cutoff value of MLR for axSpA was 0.22, with a specificity of 70.9% and sensitivity of 68.4%. CONCLUSIONS: MLR was elevated in AS patients compared to nr-axSpA patients and had a close relationship with CRP level, ESR level, and spine movements. MLR may be a reliable, cost-effective, and novel potential parameter to evaluate disease severity in axSpA.

AB - Bone fractures are some of the most common injuries annually, and many require a fixation device to help properly heal. The present study focuses on developing a bioresorbable composite that has high strength and stiffness for bone fixation applications. To achieve this, a design of experiments was performed, testing the effect of long fiber reinforcement type, matrix type, matrix amount, and particle reinforcement amount on the flexural properties of the composite. Based on these results, the ideal resorbable long fiber reinforcement, particle reinforcement, and matrix material are degummed silk fibroin, hydroxyapatite, and polylactic acid, respectively. Through further optimizations of the particle reinforcement phase a flexural modulus and strength of 13.7 GPa and 437 MPa, respectively, was achieved. Both values are among the highest found in literature, with the strength far exceeding the requirement for a fixation device and the highest for such a bioresorbable composite material, showing great promise for use as a bioresorbable fixation device. PMID- 29471254 TI - UPLC-MS/MS assay validation for tacrolimus quantitative determination in peripheral blood T CD4+ and B CD19+ lymphocytes. AB - Monitoring tacrolimus (Tac) exposure in cell matrices enriched with lymphocytes can improve Tac therapeutic drug monitoring (TDM) in solid organ transplant recipients. An UPLC-MS/MS based assay for Tac quantification in peripheral blood T CD4+ and B CD19+ lymphocytes was developed. Peripheral blood mononuclear cells (PBMC) were obtained by density gradient centrifugation and highly purified (purity >90%) T CD4+ and B CD19+ cell suspensions were acquired by magnetic negative selection from whole blood of 6 healthy volunteers. The purity of lymphocyte suspensions was checked by flow cytometry. Tac extraction was performed in a liquid-liquid zinc sulfate, methanol and acetonitrile based medium. Ascomycin was used as internal standard. The equipment used was a Waters(r) AcquityTM UPLC system (Waters Corporation, Milford, MA, USA). The chromatographic run was performed on a Waters(r) MassTrak TDM C18 (2.1 * 10 mm) column (Waters Corporation, Milford, MA, USA). at a flow rate of 0.4 mL/min. The instrument was set in electrospray positive ionization mode. The method was validated according to Clinical Laboratory Standard Institute (CLSI) guidelines and showed a high sensitivity and specificity over a range of 0-5.2 ng/mL in PBMC, 0-5.0 ng/mL in T CD4+ Lymphocytes and 0-5.3 ng/mL in B CD19+ lymphocytes. Precision was appropriate with CV of intra-assay quantifications ranging from 4.9 to 7.4%, and of inter-assay quantifications from 7.2 to 13.9%. Limit of detection and quantification were 0.100 and 0.115 ng/mL in PBMC, 0.058 and 0.109 ng/mL in T CD4+ and 0.017 and 0.150 ng/mL in B CD19+ cells. Matrix effect was not significant among all the studied matrices. Samples showed stability for Tac quantification over a period of 90 days either at room temperature or at -30 degrees C storage conditions. The method was applied to clinical samples of 20 kidney transplant recipients. Concentrations ranged from 2.200 to 11.900 ng/mL in whole blood, from 0.005 to 0.570 ng/106 cells in PBMC, from 0.081 to 1.432 ng/106 cells in T CD4+, and from 0.197 to 1.564 ng/106 cells in B CD19+ cell matrices. The method has potential applicability for Tac TDM in solid organ transplant recipients. PMID- 29471255 TI - Non-stop aptasensor capable of rapidly monitoring norovirus in a sample. AB - A cost-effective and simple biosensor was developed for the accurate and rapid monitoring of norovirus GII in a sample. The modified DNA aptamer, 5 guanines linked to conventional DNA aptamer, designed for the research, was able to rapidly capture norovirus GII in tap water as well artificial urine. In addition, the extra guanines of the modified DNA aptamer enhanced the sensitivity of biosensor with guanine chemiluminescence detection based on the principle of intra chemiluminescent resonance transfer (Intra-CRET). This is because additional high-energy intermediates formed from the reaction of extra guanines and 3, 4, 5-trimethoxylphenylglyoxal (TMPG) were able to directly transfer energy to 6-carboxylfluorescein (6-FAM) to emit bright chemiluminescence. The biosensor operated without time-consuming and tedious procedures (e.g., sample pretreatment, long and multiple incubations, washings) was able to accurately quantify trace levels of norovirus GII capsid with excellent specificity and reproducibility. The limit of detection (LOD = 3sigma) of the biosensor for norovirus GII capsids in tap water was as low as 80 ng/ml. It is expected that the new technology confirmed while developing the biosensor can be applied to devise alternative biosensors capable of rapidly quantifying various food-borne pathogens in a sample.

PMID- 29471256 TI - Consensus research priorities for paediatric status epilepticus: A Delphi study of health consumers, researchers and clinicians. AB - PURPOSE: Status epilepticus (SE) is a paediatric emergency with significant morbidity and mortality. Recommendations beyond first line care are not based on high quality evidence. Emergency physicians and neurologists are key stakeholders in managing this condition. A collaborative, widely consulted approach to identifying priorities can help direct limited research funds appropriately. The objectives of this study are to identify consensus research priorities in paediatric SE among experts and health consumers. METHODS: A three-stage Delphi process was conducted. Paediatric Neurologists and Emergency Physicians in Australia and New Zealand participated. Round one asked participants to generate three research questions important for further research in paediatric status epilepticus. Responses were refined into unique individual questions. Rounds two and three required participants to rate questions on a seven point ordinal scale. Health consumers were invited to participate by providing up to three problem areas that could be addressed by research. RESULTS: 54 experts and 76 health consumers participated in the process. Nine questions reached our definition of consensus "high priority", 21 questions achieved consensus "low priority" and seven questions did not achieve consensus. High priority areas included second line management including levetiracetam (efficacy, dose and timing), use of third line agents, induction of anaesthesia (timing and best agent), management of focal SE, and indicators of "subtle SE". Consumer priority areas included themes of treatment efficacy, aetiology, and community education. CONCLUSION: We identified nine priority research questions in paediatric SE, congruent with the health consumer theme of treatment efficacy. Future research efforts should be directed towards these priority areas. PMID- 29471258 TI - Outcomes of pregnancies in women taking antiepileptic drugs for non-epilepsy indications. AB - PURPOSE: Antiepileptic drugs (AEDs), particularly valproate (VPA), are known to be teratogens when taken by women with epilepsy (WWE), but the risk in women who take these drugs for indications other than epilepsy have been little studied. This study aims to investigate the incidence of birth defects in children born to mothers taking AEDs for non-epilepsy indications. METHODS: The Australian Pregnancy Register (APR), established in 1998, is a prospective observational study operating with ethical approval and informed written consent for participation. Of the 2066 pregnancies enrolled in the Register, 98% are WWE and the remainder received AEDs for other indications. Data from this Register was analysed to study the rates of congenital malformations (CM) in infants exposed to AEDs in utero in WWE compared to those women taking AEDs for other indications. RESULTS: The malformation rates in pregnancies of WWE taking AEDs (5%), is higher than the rates of infants born to untreated WWE (2%). There were 32 pregnancies enrolled from 29 mothers taking AEDs for indications other than epilepsy (2 women/2 pregnancies were lost to follow up). Out of 30 pregnancies, 9 of which were exposed to VPA, 1 resulted in a child with a malformation (3%) (cleft palate) on 1700 mg/day of valproate. CONCLUSIONS: This is the first attempt to assess the use of AEDs in a prospective study of women who are pregnant but do not have active epilepsy. Although underpowered, this study suggests that women taking AEDs for non-epilepsy indications have a similar risk of having a child with a CM as compared with women taking AEDs for epilepsy. Larger numbers are required to investigate the risk of AED-associated malformations in this important group. PMID- 29471259 TI - Functional genomics and assays of regulatory activity detect mechanisms at loci for lipid traits and coronary artery disease. AB - Many genome-wide association studies (GWAS) have identified signals located in non-coding regions, and an increasing number of functional genomics annotations of regulatory elements and assays of regulatory activity have been used to investigate mechanisms. Genome-wide datasets that characterize chromatin structure help detect potential regulatory elements. Assays to experimentally assess candidate variants include transcriptional reporter assays, and recently, massively parallel reporter assays (MPRAs). Additionally, the effect of candidate regulatory elements and variants on gene expression and function can be evaluated using genomic editing with the CRISPR-Cas9 technology. We highlight some recent studies that employed these strategies to identify variant effects and elucidate molecular and/or biological mechanisms at GWAS loci for lipid traits and coronary artery disease. PMID- 29471260 TI - Stress underestimation and mental health literacy of depression in Japanese workers: A cross-sectional study. AB - Appropriately estimating stress levels in daily life is important for motivating people to undertake stress-management behaviors or seek out information on stress management and mental health. People who exhibit high stress underestimation might not be interested in information on mental health, and would therefore have less knowledge of it. We investigated the association between stress underestimation tendency and mental health literacy of depression (i.e., knowledge of the recognition, prognosis, and usefulness of resources of depression) in Japanese workers. We cross-sectionally surveyed 3718 Japanese workers using a web-based questionnaire on stress underestimation, mental health literacy of depression (vignettes on people with depression), and covariates (age, education, depressive symptoms, income, and worksite size). After adjusting for covariates, high stress underestimation was associated with greater odds of not recognizing depression (i.e., choosing anything other than depression). Furthermore, these individuals had greater odds of expecting the case to improve without treatment and not selecting useful sources of support (e.g. talk over with friends/family, see a psychiatrist, take medication, see a counselor) compared to those with moderate stress underestimation. These relationships were all stronger among males than among females. Stress underestimation was related to poorer mental health literacy of depression. PMID- 29471262 TI - Generation of a human iPSC line, IISHDOi002-A, with a 46, XY/47, XYY mosaicism and belonging to an African mitochondrial haplogroup. AB - We have generated a human iPSC line, IISHDOi002-A, from commercial primary normal human dermal fibroblasts belonging to an African mitochondrial haplogroup (L3), and with a 46, XY/47, XYY mosaicism. For this purpose, reprogramming factors Oct3/4, Sox2, Klf4 and cMyc were delivered using a non-integrative methodology that involves the use of Sendai virus. PMID- 29471261 TI - Regulation of cortical and peripheral GCH1 expression and biopterin levels in schizophrenia-spectrum disorders. AB - Tetrahydrobiopterin (BH4) is an essential cofactor for dopamine, serotonin and nitric oxide synthesis. Deficits of plasma total biopterin (a measure of BH4) have been described in schizophrenia and schizoaffective disorder. GCH1 encodes the first and rate-limiting enzyme in BH4 synthesis. Peripheral GCH1 expression is lower in first episode psychosis patients versus controls, and we hypothesized that a GCH1 promoter polymorphism associated with psychiatric illness, contributes to regulation of both GCH1 expression and BH4 levels. We tested this hypothesis in 120 subjects (85 patients with schizophrenia or schizoaffective disorder and 35 controls): Patients with the rs10137071 A allele had significantly lower plasma biopterin than GG patients and controls. In additional samples we assessed the relationship between genotype and diagnosis (schizophrenia or control) on GCH1 expression in the prefrontal cortex (n = 67) and peripheral leukocytes (n = 53). We found a significant linear relationship between GCH1 and study group in the CNS and periphery, with A allele patients having lower expression. Finally, in antipsychotic naive patients (n = 13) we tested for an effect of medication on GCH1: Expression rose significantly after the onset of medication, primarily in A allele patients. These data suggest the potential for personalized genetic approaches to ameliorating BH4 deficits in schizophrenia-spectrum disorders. PMID- 29471263 TI - Predictive models for tyrosinase inhibitors: Challenges from heterogeneous activity data determined by different experimental protocols. AB - Quantitative Structure-Activity Relationship (QSAR) models of tyrosinase inhibitors were built using Random Forest (RF) algorithm and evaluated by the out of-bag estimation (R2OOB) and 10-fold cross validation (Q2CV). We found that the performances of QSAR models were closely correlated with the systematic errors of inhibitory activities of tyrosinase inhibitors arising from the different measuring protocols. By defining ERRsys, outliers with larger errors can be efficiently identified and removed from heterogeneous activity data. A reasonable QSAR model (R2OOB of 0.74 and Q2CV of 0.80) was obtained by the exclusion of 13 outliers with larger systematic errors. It is a clear example of the challenge for QSAR model that can overwhelm heterogeneous data from different experimental protocols. PMID- 29471264 TI - Collective transcriptomic deregulation of hypertrophic and dilated cardiomyopathy - Importance of fibrotic mechanism in heart failure. AB - Myocardial fibrosis reside a common pathological feature in hypertrophic and dilated cardiomyopathy that results in ventricular dysfunction leading to heart failure. Though several studies reported the role of fibrosis in cardiac diseases, their pathologic mechanisms leading to heart failure remains unclear. A few studies have proposed integrated analysis of microarray information and protein-protein interaction (PPI) systems to discover subnetwork markers related to diagnosis and prognosis of the disease. In addition to PPI networks, we incorporated miRNAs and transcription factors to find the putative miRNAs and transcription factors that might regulate the pathological process and progression of cardiomyopathy and their further progression to heart failure. The important submodules from network revealed the significance of Small Leucine Rich Proteoglycans (SLRPs), Extracellular matrix (ECM) related proteins and complement system in fibrosis. Sequence analysis of different SLRPs suggest that Keratocan and Fibromodulin possesses the same collagen binding site. A predicted mechanism of TGFbeta1 shows the involvement of different pathway of HCM and DCM in progression of heart failure. PMID- 29471265 TI - Role of RpoS in stress resistance, quorum sensing and spoilage potential of Pseudomonas fluorescens. AB - Microorganism activities are considered the main cause of most food spoilage, leading to great economic losses. Pseudomonas fluorescens is a Gram-negative bacterium that is widely found in food and has high spoilage activity. RpoS is considered an important global regulator involved in stress survival and virulence in many pathogens. Thus, it is very possible that RpoS plays an important role in spoilage regulation in P. fluorescens. In this study an in frame deletion mutation of rpoS was constructed to explore its function in P. fluorescens. The results showed that RpoS positively regulated the resistance of P. fluorescens to H2O2, heat, ethanol and crystal violet, negatively regulated the resistance to acetic acid, and had no effect on the resistance to NaCl. Further studies indicated that acylated homoserine lactone (AHL) production and the transcription levels of five AHL-related genes were significantly decreased in the rpoS mutant compared with those in the wild-type strain. Interestingly, the two homologous genes coding for AHL synthases contained RpoS-dependent -10 elements, suggesting that AHL quorum sensing is directly regulated by RpoS. RpoS also contributed to the spoilage activities of P. fluorescens by regulating extracellular protease and total volatile basic nitrogen (TVB-N) production in sterilized salmon juice. Our results reveal that RpoS was a key regulatory factor involved in stress resistance, the AHL quorum sensing system, and spoilage potential of P. fluorescens. Our study may benefit food safety control and food preservation. PMID- 29471266 TI - Genetic characterization of respiratory syncytial virus highlights a new BA genotype and emergence of the ON1 genotype in Lyon, France, between 2010 and 2014. AB - BACKGROUND: Respiratory syncytial virus (RSV) is a well-recognized cause of respiratory tract infections. Based on G gene variations, 11 RSV-A and 36 RSV-B genotypes have been described to date. The ON1 genotype was detected in Ontario in 2010 and subsequently reported in several countries. OBJECTIVES: The objective of the present study was to investigate for the first time the RSV epidemiology and genotype diversity in France between 2010 and 2014. STUDY DESIGN: All respiratory samples received from patients with influenza-like illness or respiratory tract infection were screened for RSV infection by RT-PCR. The results were stratified according to winter season. Among the RSV-positive cases, 117 samples were further investigated for phylogenetic analysis out of 150 randomly selected for sequencing. RESULTS: Among the 20,359 cases screened, 14% of the cases were RSV-positive. RSV-A was predominant during the four winter seasons. The first ON1 variant was detected during the 2010-2011 winter and reached 85% of all RSV-A-positive cases in 2013-2014. Most RSV-B was classified as BA9 and BA10 genotypes but a new genotype (BA-Ly) was described. CONCLUSION: As reported in different countries, ON1 variants were firstly detected in 2011 and became the predominant RSV-A genotype in Lyon. Among RSV-B, BA9 was predominant but detected alongside BA10 or a transient genotype (BA-Ly). PMID- 29471267 TI - The effectiveness of traditional Chinese medicine-based lifestyle interventions on biomedical, psychosocial, and behavioral outcomes in individuals with type 2 diabetes: A systematic review with meta-analysis. AB - BACKGROUND: Integrative diabetes care, which combines conventional diabetes therapy with traditional Chinese medicine (TCM)-based interventions, has gained popularity worldwide. Numerous TCM-based lifestyle modification approaches have been proposed for individuals with type 2 diabetes (T2DM). OBJECTIVES: To synthesize and present the best available evidence on the effectiveness of TCM based lifestyle interventions in individuals with T2DM. DESIGN: We undertook a systematic review of randomized controlled trials or controlled clinical trials. DATA SOURCES: Six English and four Chinese electronic databases were searched from their inceptions to December 2016. REVIEW METHODS: Trials investigating the effectiveness of various TCM-based lifestyle interventions among adults with T2DM were reviewed. Studies were excluded if TCM-based lifestyle interventions were only part of the intervention regimen. Two reviewers independently selected studies according to pre-specified inclusion and exclusion criteria and appraised the risk of bias of the included studies. One reviewer extracted details of the included studies and the second reviewer checked the extracted data critically. When feasible, data were statistically pooled for meta-analysis. Otherwise, narrative summaries were used. RESULTS: Twenty-four studies were included. The pooled analysis of the eight studies on tai chi showed tai chi practice for at least 150 min per week was beneficial in lowering glycosylated hemoglobin (mean difference, -1.48%; 95%CI, -2.58% to -0.39%; p < 0.001). Tai chi was effective in reducing fasting blood glucose (mean difference, -1.14 mmol/L; 95%CI, -1.78 to 0.50 mmol/L; p < 0.001) and body mass index (mean difference, -0.62; 95%CI, -1.14 to -0.11; p = 0.02), and improving quality of life. The effects of tai chi on blood pressure and waist circumference were inconclusive due to the limited number of studies. The meta-analysis of the 12 studies on ba duan jin demonstrated beneficial effects on glycosylated hemoglobin (mean difference, 0.77%; 95%CI, -0.97% to -0.56%; p < 0.001), fasting blood glucose (mean difference, -0.82 mmol/L; 95%CI, -1.05 to -0.59 mmol/L; p < 0.001), body mass index (mean difference, -2.77; 95%CI, -4.11 to -1.43; p < 0.001), and depression (mean difference, -4.53; 95%CI, -7.12 to -1.94; p < 0.001). Conclusions on the effects of ba duan jin on quality of life cannot be drawn because only two studies measured the outcome. Evidence regarding the effectiveness of other TCM based lifestyle interventions is limited. CONCLUSIONS: Tai chi and ba duan jin are potentially effective options for individuals with T2DM to improve biomedical and psychosocial well-being. Further well-designed studies are needed to explore the optimal intervention dose and to investigate the effectiveness of other TCM based lifestyle interventions. PMID- 29471268 TI - Clydonella sawyeri n. sp. (Amoebozoa, Vannellida): Morphological and molecular study and a re-definition of the genus Clydonella Sawyer, 1975. AB - We isolated and described a brackish-water amoeba, Clydonella sawyeri n. sp. (Amoebozoa, Vannellida), from the littoral habitat in Kandalaksha Bay (The White Sea, northwestern Russia). Morphology of this amoeba corresponds to the initially proposed diagnosis of the genus Clydonella Sawyer, 1975, although it is sufficiently different from other described species of this genus to warrant a distinct species designation. Phylogenetic analysis based on the small-subunit rRNA gene shows that this species is closely related to the two previously studied ATCC strains identified as Clydonella sp., for which only ultrastructural and molecular data were published. Cytochrome oxidase subunit 1 (COI) gene sequence of the studied species was for the first time obtained for Clydonella. Analysis of this marker shows that this genus belongs to Vannellida and is separated from the other vannellids sampled to date. Phylogenetic analysis of the concatenated SSU rRNA and COI genes dataset yields the best resolved position of Clydonella compared to both markers when analysed separately. Based on the data presented we finally link light microscopic, ultrastructural and molecular data in a description of a single strain, which allows a refinement of the diagnosis of the genus Clydonella. PMID- 29471269 TI - How to build a phagosome: new concepts for an old process. AB - Phagocytosis is a complex and elegant mechanism requiring finely coordinated deformation and restructuring of the membrane and the underlying cytoskeleton. Here we discuss the early events of receptor clustering and engagement required for signal transduction and actin remodeling. In addition, we summarize recent studies of the mechanisms whereby the nascent phagosome seals and evolves into a degradative phagolysosome by a process that seemingly involves the autophagic machinery. These studies provided new insights of the molecular basis of this long-appreciated, essential homeostatic process. PMID- 29471270 TI - Validation of time to task performance assessment method in simulation: A comparative design study. AB - BACKGROUND: There is a lack of objective and valid measures for assessing nursing clinical competence which could adversely impact patient safety. Therefore, we evaluated an objective assessment of clinical competence, Time to Task (ability to perform specific, critical nursing care activities within 5 min), and compared it to two subjective measures, (Lasater Clinical Judgement Rubric [LCJR] and common "pass/fail" assessment). DESIGN/METHODS: Using a prospective, "Known Groups" (Expert vs. Novice nurses) comparative design, Expert nurses (ICU nurses with >5 years of ICU experience) and Novice nurses (senior prelicensure nursing students) participated individually in a simulation of a patient in decompensated heart failure. Fourteen nursing instructors or preceptors, blinded to group assignment, reviewed 28 simulation videos (15 Expert and 13 Novice) and scored them using the LCJR and pass/fail assessments. Time to Task assessment was scored based on time thresholds for specific nursing actions prospectively set by an expert clinical panel. Statistical analysis consisted of Medians Test and sensitivity and specificity analyses. RESULTS: The LCJR total score was significantly different between Experts and Novices (p < 0.01) and revealed adequate sensitivity (ability to correctly identify "Expert" nurses; 0.72) but had a low specificity (ability to correctly identify "Novice" nurses; 0.40). For the subjective measure 'pass/fail', sensitivity was high (0.90) but specificity was low (0.47). The Time to Task measure had statistical significance between Expert and Novice groups (p < 0.01) and sensitivity (0.80) and specificity (0.85) were good. CONCLUSION: Commonly used subjective measures of clinical nursing competence have difficulties with achieving acceptable specificity. However, an objective measure, Time to Task, had good sensitivity and specificity in differentiating between groups. While more than one assessment instrument should be used to determine nurse competency, an objective measure, such as Time to Task, warrants further study. PMID- 29471271 TI - Design thinking: Opportunities for application in nursing education. PMID- 29471272 TI - Gene architecture and expression analyses provide insights into the role of glutathione peroxidases (GPXs) in bread wheat (Triticum aestivum L.). AB - Glutathione peroxidases (GPXs) are redox sensor proteins that maintain a steady state of H2O2 in plant cells. They exhibit distinct sub-cellular localization and have diverse functionality in response to different stimuli. In this study, a total of 14 TaGPX genes and three splice variants were identified in the genome of Triticum aestivum and evaluated for various physicochemical properties. The TaGPX genes were scattered on the various chromosomes of the A, B, and D sub genomes and clustered into five homeologous groups based on high sequence homology. The majority of genes were derived from the B sub-genome and localized on chromosome 2. The intron-exon organization, motif and domain architecture, and phylogenetic analyses revealed the conserved nature of TaGPXs. The occurrence of both development-related and stress-responsive cis-acting elements in the promoter region, the differential expression of these genes during various developmental stages, and the modulation of expression in the presence of biotic and abiotic stresses suggested their diverse role in T. aestivum. The majority of TaGPX genes showed higher expression in various leaf developmental stages. However, TaGPX1-A1 was upregulated in the presence of each abiotic stress treatment. A co-expression analysis revealed the interaction of TaGPXs with numerous development and stress-related genes, which indicated their vital role in numerous biological processes. Our study revealed the opportunities for further characterization of individual TaGPX proteins, which might be useful in designing future crop improvement strategies. PMID- 29471273 TI - Effect of simultaneously induced environmental stimuli on electrical signalling and gas exchange in maize plants. AB - Electrical signalling in response to environmental stimuli is a well-known phenomenon in higher plants. For example, in maize, different stimuli, such as wounding or re-irrigation after drought, incite characteristic electrical signals which have quite particular effects on gas exchange. What is less well understood is how plants (specifically maize) respond when two different environmental stimuli are applied simultaneously. To explore this, a three-stage experiment was designed. In the first stage, drought conditions were simulated by decreasing the soil water content to 30-40 % of field capacity. In these conditions, and in contrast to well-watered plants, the maize exhibited only 60-70% of the original level of stomatal conductance and 50-60 % of the original photosynthesis rate. In the second stage of the experiment the plants were re-irrigated and heat stimulated separately. Re-irrigation led to specific electrical signals followed by a gradual increase of gas exchange. In contrast, after heat stimulation of a leaf an electrical signal was evoked that reduced the net CO2-uptake rate as well as stomatal conductance. In the third stage, to elucidate how plants process simultaneous re-irrigation and heat stimulation, the drought-stressed maize plants were re-watered and heat-stimulated at the same time. Results showed a two phase response. In the first phase there was a rapid decrease in both the CO2 uptake rate and the stomatal conductance, while in the second phase each of these parameters increased gradually. Thus, the results strongly support the view that the responses from both stimuli were combined, indicating that maize plants can process simultaneously applied stimuli. PMID- 29471274 TI - Accession-specific life strategies affect responses in leaves of Arabidopsis thaliana plants exposed to excess Cu and Cd. AB - The natural accession Columbia (Col-0) is considered as the reference genome of the model plant Arabidopsis thaliana. Nonetheless, Col-0 plants are more sensitive to excess copper (Cu) and cadmium (Cd) than other widely used accessions such as Wassilewskija (Ws) plants. In the current study, this accession-specific metal sensitivity is further explored by comparing the responses in leaves of Col-0 and Ws plants exposed to excess Cu and Cd. Our results suggest that different life strategies favored by both accessions under physiological conditions affect their response to metal exposure. While Col-0 plants mainly invest in metal detoxification, Ws plants center on nutrient homeostasis. In particular, the higher expression of genes related to Cu homeostasis genes in non-exposed conditions indicates that Ws plants possess a constitutively efficient metal homeostasis. On the other hand, oxidative stress related MAPK signaling appears to be boosted in leaves of Col-0 plants exposed to excess Cu. Furthermore, the upregulation of the glutathione (GSH) biosynthesis GSH2 gene and the increased GSH concentration after Cd exposure suggest the activation of detoxification mechanisms, such as phytochelatin production, to counteract the more severe Cd-induced oxidative stress in leaves of Col-0 plants. Exposure to Cd also led to a more pronounced ethylene signaling response in leaves of Col-0 as compared to Ws plants, which could be related to Cd-induced GSH metabolism. In conclusion, accession-specific life strategies clearly affect the way in which leaves of A. thaliana plants cope with excess Cu and Cd. PMID- 29471275 TI - Frequency-agile gyrotron for electron decoupling and pulsed dynamic nuclear polarization. AB - We describe a frequency-agile gyrotron which can generate frequency-chirped microwave pulses. An arbitrary waveform generator (AWG) within the NMR spectrometer controls the microwave frequency, enabling synchronized pulsed control of both electron and nuclear spins. We demonstrate that the acceleration of emitted electrons, and thus the microwave frequency, can be quickly changed by varying the anode voltage. This strategy results in much faster frequency response than can be achieved by changing the potential of the electron emitter, and does not require a custom triode electron gun. The gyrotron frequency can be swept with a rate of 20 MHz/MUs over a 670 MHz bandwidth in a static magnetic field. We have already implemented time-domain electron decoupling with dynamic nuclear polarization (DNP) magic angle spinning (MAS) with this device. In this contribution, we show frequency-swept DNP enhancement profiles recorded without changing the NMR magnet or probe. The profile of endofullerenes exhibits a DNP profile with a <10 MHz linewidth, indicating that the device also has sufficient frequency stability, and therefore phase stability, to implement pulsed DNP mechanisms such as the frequency-swept solid effect. We describe schematics of the mechanical and vacuum construction of the device which includes a novel flanged sapphire window assembly. Finally, we discuss how commercially available continuous-wave gyrotrons can potentially be converted into similar frequency agile high-power microwave sources. PMID- 29471276 TI - Optimized phases for the acquisition of J-spectra in coupled spin systems for thermally and PHIP polarized molecules. AB - We demonstrate that the relative phases in the refocusing pulses of multipulse sequences can compensate for pulse errors and off-resonant effects, which are commonly encountered in J-spectroscopy when CPMG is used for acquisition. The use of supercycles has been considered many times in the past, but always from the view point of time-domain NMR, that is, in an effort to lengthen the decay of the magnetization. Here we use simple spin-coupled systems, in which the quantum evolution of the system can be simulated and contrasted to experimental results. In order to explore fine details, we resort to partial J-spectroscopy, that is, to the acquisition of J-spectra of a defined multiplet, which is acquired with a suitable digital filter. We unambiguously show that when finite radiofrequency pulses are considered, the off-resonance effects on nearby multiplets affects the dynamics of the spins within the spectral window under acquisition. Moreover, the most robust phase cycling scheme for our setup consists of a 4-pulse cycle, with phases yyyy? or xxxx? for an excitation pulse with phase x. We show simulated and experimental results in both thermally polarized and PHIP hyperpolarized systems. PMID- 29471277 TI - Simultaneous acquisition for T2-T2 Exchange and T1-T2 correlation NMR experiments. AB - The NMR measurements of longitudinal and transverse relaxation times and its multidimensional correlations provide useful information about molecular dynamics. However, these experiments are very time-consuming, and many researchers proposed faster experiments to reduce this issue. This paper presents a new way to simultaneously perform T2-T2 Exchange and T1-T2 correlation experiments by taking the advantage of the storage time and the two steps phase cycling used for running the relaxation exchange experiment. The data corresponding to each step is either summed or subtracted to produce the T2-T2 and T1-T2 data, enhancing the information obtained while maintaining the experiment duration. Comparing the results from this technique with traditional NMR experiments it was possible to validate the method. PMID- 29471278 TI - Intestinal bacteria in bioaerosols and factors affecting their survival in two oxidation ditch process municipal wastewater treatment plants located in different regions. AB - Samples from two oxidation ditch process municipal wastewater treatment plants (MWTPs) (HJK and GXQ) in two regions of China were analysed for bacteria, particles, total organic carbon, and water-soluble ions in bioaerosols. Diversity and potential pathogen populations were evaluated by high-throughput sequencing. Bioaerosol sources, factors affecting intestinal bacterial survival, and the relationship between bioaerosols and water were analysed by Source tracker and partial least squares-discriminant, principal component, and canonical correspondence analyses. Culturable bacteria concentrations were 110-846 and 27 579 CFU/m3 at HJK and GXQ, respectively. Intestinal bacteria constituted 6-33% of bacteria. Biochemical reaction tank, sludge dewatering house (SDH), and fine screen samples showed the greatest contribution to bioaerosol contamination. Enterobacter aerogenes was the main intestinal bacteria (> 99.5%) in HJK and detected at each sampling site. Enterobacter aerogenes (98.67% in SDH), Aeromonas sp. (76.3% in biochemical reaction tank), and Acinetobacter baumannii (99.89% in fine screens) were the main intestinal bacteria in GXQ. Total suspended particulate masses in SDH were 229.46 and 141.6 MUg/m3 in HJK and GXQ, respectively. Percentages of insoluble compounds in total suspended particulates decreased as height increased. The main soluble ions in bioaerosols were Ca2+, Na+, Cl-, and SO42-, which ranged from 3.8 to 27.55 MUg/m3 in the MWTPs. Water was a main source of intestinal bacteria in bioaerosols from the MWTPs. Bioaerosols in HJK but not in GXQ were closely related. Relative humidity and some ions positively influenced intestinal bacteria in bioaerosols, while wind speed and solar illumination had a negative influence.

AB - During its life cycle, plant has to cope with a number of abiotic stresses including cadmium stress. Cadmium (Cd) is highly toxic to plant and greatly influences its growth and entire metabolism. Antioxidants have to enable plant to beat such stresses. Therefore, effects of ascorbate (AsA), proline (Pro) and glutathione (GSH) applied, as seed soaking solutions, singly or in a sequence on cucumber transplant growth, physio-biochemical attributes and antioxidant defense system activity were investigated under 2 mM Cd stress. Adding Cd to transplants in irrigation water reduced photosynthetic efficiency, and nutrient (K+ and Ca2+) contents, while increased the activity of defense systems (non-enzymatic and enzymatic antioxidants) and Cd2+ contents in roots and leaves. Exogenous AsA, Pro and GSH applied singly or in a sequence improved transplant growth (e.g., shoot length, leaf area, shoot fresh weight and shoot dry weight), photosynthetic efficiency (i.e., SPAD chlorophyll, Fv/Fm and PI), transplant health (i.e., increased leaf MSI and RWC, and decreased root and leaf Cd2+ contents), antioxidant defense systems activity (enzymatic; superoxide dismutase, catalase, glutathione reductase and ascorbate peroxidase, and non-enzymatic; Pro, AsA and GSH antioxidants) and nutrient (K+ and Ca2+) contents. These positive results were obtained under irrigation with or without Cd, AsA. Sequenced AsA-Pro-GSH was the best treatment of which this study recommends to use, followed by GSH treatment, for growing cucumber transplants under Cd stress. PMID- 29471280 TI - Stretchable wireless system for sweat pH monitoring. AB - Sensor-laden wearable systems that are capable of providing continuous measurement of key physiological parameters coupled with data storage, drug delivery and feedback therapy have attracted huge interest. Here we report a stretchable wireless system for sweat pH monitoring, which is able to withstand up to 53% uniaxial strain and more than 500 cycles to 30% strain. The stretchability of the pH sensor patch is provided by a pair of serpentine-shaped stretchable interconnects. The pH sensing electrode is made of graphite polyurethane composite, which is suitable for biosensor application. The sensing patch validated through in-depth electrochemical studies, exhibits a pH sensitivity of 11.13 +/- 5.8 mV/pH with a maximum response time of 8 s. Interference study of ions and analyte (Na+, K+ and glucose) in test solutions shows negligible influence on the pH sensor performance. The pH data can be wirelessly and continuously transmitted to smartphone through a stretchable radio frequency-identification antenna, of which the radiating performance is stable under 20% strain, as proved by vector network analyzer measurement. To evaluate the full system, the pH value of a human sweat equivalent solution has been measured and wirelessly transmitted to a custom-developed smart phone App. PMID- 29471281 TI - Theoretical and experimental study for the biomimetic recognition of levothyroxine hormone on magnetic molecularly imprinted polymer. AB - This study addresses the rational design of a magnetic molecularly imprinted polymer (magnetic-MIP) for the selective recognition of the hormone levothyroxine. The theoretical study was carried out by the density functional theory (DFT) computations considering dispersion interaction energies, and using the D2 Grimme's correction. The B97-D/def2-SV(P)/PCM method is used not only for studying the structure of the template the and monomer-monomer interactions, but also to assess the stoichiometry, noncovalent binding energies, solvation effects and thermodynamics properties such as binding energy. Among the 13 monomers studied in silico, itaconic acid is the most suitable according to the thermodynamic values. In order to assess the efficiency of the computational study, three different magnetic-MIPs based on itaconic acid, acrylic acid and acrylamide were synthesized and experimentally compared. The theoretical results are in agreement with experimental binding studies based on laser confocal microscopy, magneto-actuated immunoassay and electrochemical sensing. Furthermore, and for the first time, the direct electrochemical sensing of L thyroxine preconcentrated on magnetic-MIP was successfully performed on magneto actuated electrodes within 30 min with a limit of detection of as low as 0.0356 ng mL-1 which cover the clinical range of total L-thyroxine. Finally, the main analytical features were compared with the gold standard method based on commercial competitive immunoassays. This work provides a thoughtful strategy for magnetic molecularly imprinted polymer design, synthesis and application, opening new perspectives in the integration of these materials in magneto-actuated approaches for replacing specific antibodies in biosensors and microfluidic devices. PMID- 29471282 TI - AuNPs/CNOs/SWCNTs/chitosan-nanocomposite modified electrochemical sensor for the label-free detection of carcinoembryonic antigen. AB - In this work, a nanocomposite of gold nanoparticles (AuNPs), carbon nano-onions (CNOs), single-walled carbon nanotubes (SWCNTs) and chitosan (CS) (AuNPs/CNOs/SWCNTs/CS) was prepared for the development of highly sensitive electrochemical immunosensor for the detection of carcinoembryonic antigen (CEA), clinical tumor marker. Firstly, layer-by-layer fabrication of the CEA immunosensors was studied using cyclic voltammetry (CV) and square wave voltammetry (SWV). By combining the advantages of large surface area and electronic properties of AuNPs, CNOs, SWCNTs, and film forming properties of CS, AuNPs/CNOs/SWCNTs/CS-nanocomposite-modified glassy carbon electrode showed a 200% increase in effective surface area and electronic conductivity. The calibration plot gave a negative linear relationship between log[concentration] of CEA and electrical current with a correlation coefficient of 0.9875. The CEA-immunosensor demonstrated a wide linear detection range of 100 fg mL-1 to 400 ng mL-1 with a low detection limit of 100 fg mL-1. In addition to high sensitivity, reproducibility and large stability, CEA-immunosensor provided an excellent selectivity and resistant-to-interference in the presence of other antigens in serum and hence a potential to be used with real samples. PMID- 29471283 TI - Task-residual functional connectivity of language and attention networks. AB - Functional connectivity using task-residual data capitalizes on remaining variance after mean task-related signal is removed from a time series. The degree of network specificity in language and attention domains featured by task residual and resting-state data types were compared. Functional connectivity based on task-residual data evidenced stronger laterality of the language and attention connections and thus greater network specificity compared to resting state functional connectivity of the same connections. Covariance between network nodes of task-residuals may thus reflect the degree to which two regions are coordinated in their specific activity, rather than a general shared co activation. Task-residual functional connectivity provides complementary data to that of resting-state, emphasizing network relationships during task engagement. PMID- 29471285 TI - Effects of docosahexanoic acid supplementation on inflammatory and subcutaneous adipose tissue gene expression in HIV-infected patients on combination antiretroviral therapy (cART). A sub-study of a randomized, double-blind, placebo controlled study. AB - BACKGROUND: Omega-3 fatty acids have the potential to decrease inflammation and modify gene transcription. Whether docosahexanoic acid (DHA) supplementation can modify systemic inflammatory and subcutaneous adipose tissue (SAT) gene expression in HIV-infected patients is unknown. METHODS: A randomized, double blind, placebo-controlled trial that enrolled 84 antiretroviral-treated patients who had fasting TG levels from 2.26 to 5.65 mmol/l and received DHA or placebo for 48 weeks was performed (ClinicalTrials.gov, NCT02005900). Systemic inflammatory and SAT gene expression was assessed at baseline and at week 48 in 39 patients. RESULTS: Patients receiving DHA had a 43.9% median decline in fasting TG levels at week 4 (IQR: -31% to -56%), compared with -2.9% (-18.6% to 16.5%) in the placebo group (P < 0.0001). High sensitivity C reactive protein (hsCRP) and arachidonic acid levels significantly decreased in the DHA group. Adipogenesis-related and mitochondrial-related gene expression did not experience significant changes. Mitochondrial DNA (mtDNA) significantly decreased in the placebo group. SAT inflammation-related gene expression (Tumor necrosis factor alpha [TNF-alpha], and monocyte chemoattractant protein-1 [MCP-1]) significantly decreased in the DHA group. CONCLUSIONS: DHA supplementation down-regulated inflammatory gene expression in SAT. DHA impact on markers of systemic inflammation was restricted to hsCRP and arachidonic acid.

PMID- 29471284 TI - Adverse metabolic effects in fish exposed to contaminants of emerging concern in the field and laboratory. AB - Several metabolic parameters were assessed in juvenile Chinook salmon (Oncorhynchus tshawytscha) and staghorn sculpin (Leptocottus armatus) residing in two estuaries receiving wastewater treatment effluent and one reference estuary. We also conducted a laboratory study with fish dosed for 32 days with 16 of the most common contaminants of emerging concern (CECs) detected in feral fish. Several blood chemistry parameters and other indicators of health were measured in fish from the field and laboratory study that were used to assess potential metabolic disruption. The blood chemistry values observed in feral juvenile Chinook salmon were relatively consistent among fish collected from effluent impacted sites and substantially different compared to reference site fish. These responses were more pronounced in Chinook salmon, which is supported by the disparity in accumulated CECs. The blood chemistry results for juvenile Chinook salmon collected at effluent-impacted sites exhibited a pattern generally consistent with starvation because of similarities to observations from studies of food-deprived fish; however, this response is not consistent with physical starvation but may be contaminant induced. The altered blood chemistry parameters are useful as an early indicator of metabolic stress, even though organismal characteristics (lipid content and condition factor) were not different among sites indicating an early response. Evidence of metabolic disruption was also observed in juvenile Chinook salmon that were exposed in the laboratory to a limited mixture of CECs; however, the plasma parameters were qualitatively different possibly due to exposure route, season, or the suite of CECs. Growth was impaired in the high-dose fish during the dosing phase and the low- and medium-dose fish assayed after 2 weeks of depuration. Overall, these results are consistent with metabolic disruption for fish exposed to CECs, which may result in early mortality or an impaired ability to compete for limited resources. PMID- 29471287 TI - Preoperative Grading of Glioma Using Dynamic Susceptibility Contrast MRI: Relative Cerebral Blood Volume Analysis of Intra-tumoural and Peri-tumoural Tissue. AB - OBJECTIVES: To assess the usefulness of intra-tumor and peri-tumoral relative cerebral blood volume (rCBV) in preoperative glioma grading. PATIENTS AND METHODS: 21 patients with histopathologically confirmed glioma were included. Imaging was achieved on a 1.5T MRI scanner. Dynamic susceptibility contrast (DSC) MRI was performed using T2* weighted gradient echo-planner imaging (EPI). Multiple regions of interest (ROIs) have been drawn in the hotspots regions, the highest ROI has been selected to represent the rCBV of each intra-tumoral and peri-tumoral regions. Based on histopathology, tumors were subdivided into low grade and high grade. Receiver operating characteristic analysis (ROC) of rCBV, of both intra-tumoral and peri-tumoral regions, was performed to find cut-off values between high and low-grade tumors. The resulting sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were calculated. RESULTS: Based on the histopathology, high-grade glioma (HGG) represented 76.2% whereas low-grade glioma (LGG) represented 23.8%. Both intra tumoral and peri-tumoral rCBV of HGG were significantly higher than those of LGG. A cut-off value >2.9 for intra-tumoral rCBV provided sensitivity, specificity, and accuracy of 80%, 100%, and 85.7% respectively to differentiate between HGG and LGG. Additionally, the cut-off value >0.7 for peri-tumoral rCBV provided sensitivity, specificity, and accuracy of 100%, 66.6%, and 90.5% respectively to differentiate between HGG and LGG. CONCLUSION: rCBV of each of intra-tumoral and peri-tumoral rCBV are significantly reliable for the preoperative distinction between HGG and LGG. Combined intra-tumoral and peri-tumoral rCBV provides overall better diagnostic accuracy and helps to decrease the invasive intervention for non-surgical candidates. PMID- 29471288 TI - Clinically aggressive phenotype: A clinicopathological case series of atypical pituitary adenomas. AB - OBJECTIVE: Atypical pituitary adenomas were relatively more malignant lesions defined by WHO criteria. However, not all of them show clinically aggressive behavior. Thus, the current WHO criteria of atypical adenoma didn't seem to be enough to distinguish clinically aggressive adenoma. Therefore, we would like to identify other clinical factors in a cohort of atypical pituitary adenomas to a better identification of clinical aggressiveness. PATIENTS AND METHODS: In order to verify predictors of clinically aggressive phenotype among atypical pituitary adenomas, we retrospectively analyzed the clinical characteristics and therapeutic outcomes of consecutive 49 cases. RESULTS: Totally, 26 cases were identified as clinically aggressive pituitary adenoma. Clinically aggressive lesions were more likely to be functional (46.2% vs. 17.4%, p = .0388) and be detected in males (65.4% vs. 21.7%, p = .0037). Clinically aggressive adenomas also had higher Ki-67 index [5.0 (5.3)% vs. 4.1 (1.3)%, p = .0011] and presented bigger tumor size [11.83 (11.95) cm3 vs. 5.39 (6.08) cm3, p = .0174]. In multivariate analysis, gender (p = .017), functional status (p = .009) and Ki-67 index (p = .024) were independent predictors of clinical aggressiveness. Further analysis revealed that Ki-67 index of more than 4.45% was associated with worse progression-free survival. CONCLUSIONS: Gender, functional status, tumor size and Ki-67 index >=4.45% were associated with clinical aggressiveness. A clinicopathological classification of pituitary adenomas may be useful to determine who should be under closer radiological follow-up or followed multimodal treatment strategy. PMID- 29471290 TI - Presence of Kidney Disease as an Outcome Predictor in Patients with Pulmonary Arterial Hypertension. AB - BACKGROUND: Pulmonary arterial hypertension (PAH) may lead to right heart failure and subsequently alter glomerular filtration rates (GFR). Chronic kidney disease (CKD, GFR <60 mL/min/1.73 m2) may also adversely affect PAH prognosis. This study aimed to assess how right heart hemodynamics was associated with reduced estimated GFR (eGFR) and the association of CKD with survival in PAH patients. METHODS: In a prospective PAH cohort (2003-2012), invasive hemodynamics and eGFR were collected at diagnosis (179 patients) and during follow-up (159 patients). The prevalence of CKD was assessed at PAH diagnosis. Variables, including hemodynamics, associated with reduced eGFR at diagnosis and during follow-up were tested in multivariate analysis. The association of CKD with survival was evaluated using a multivariate Cox regression model. RESULTS: At diagnosis, mean age was 60.4 +/- 16.5 years, mean pulmonary arterial pressure was 43 +/- 12 mm Hg, and eGFR was 74.4 +/- 26.4 mL/min/1.73 m2. CKD was observed in 52 incident patients (29%). Independent determinants of reduced eGFR at diagnosis were age, systemic hypertension, and decreased cardiac index. Independent determinants of reduced eGFR during follow-up were age, female gender, PAH etiology, systemic hypertension, decreased cardiac index, and increased right atrial pressure. Age >=60 years, female gender, NYHA 4, and CKD at diagnosis were independently associated with decreased survival. The adjusted hazards ratio for death associated with CKD was 1.81 (95% confidence interval [1.01-3.25]). CONCLUSION: CKD is frequent at PAH diagnosis and is independently associated with increased mortality. Right heart failure may induce renal hypoperfusion and congestion, and is associated with eGFR decrease. PMID- 29471289 TI - Single Nucleotide Polymorphism Facilitated Down-Regulation of the Cohesin Stromal Antigen-1: Implications for Colorectal Cancer Racial Disparities. AB - The biological underpinnings for racial disparities in colorectal cancer (CRC) incidence remain to be elucidated. We have previously reported that the cohesin SA-1 down-regulation is an early event in colon carcinogenesis which is dramatically accentuated in African-Americans. In order to investigate the mechanism, we evaluated single nucleotide polymorphisms (SNPs) for association with SA-1-related outcomes followed by gene editing of candidate SNP. We observed that rs34149860 SNP was significantly associated with a lower colonic mucosal SA 1 expression and evaluation of public databases showed striking racial discordance. Given that the predicted SNP would alter miR-29b binding site, we used CRISPR knock-in in CRC cells and demonstrated that the SNP but not wild-type had profound alterations in SA-1 expression with miR-29b inhibitor. This is the first demonstration of high-order chromatin regulators as a modulator of racial differences, risk alteration with SNPs and finally specific modulation by microRNAs. PMID- 29471292 TI - Step Numbers and Hoehn-Yahr Stage after Six Years. AB - BACKGROUND: Freezing of gait (FOG) has been linked to increased numbers of steps taken while walking. We tested the hypothesis that an increased number of steps associated with FOG might predict the exacerbation of the severity of Parkinson's disease (PD). METHODS: We prospectively studied 26 patients. Clinical assessments were performed and balance was evaluated in 30 patients with Hoehn-Yahr stage III PD 6 years previously. Gait parameters were analyzed with the use of an originally designed, suddenly narrowed path. PD-related independent variables, balance investigation-related variables, and gait-independent-related variables were analyzed by multiple logistic regression analysis. RESULTS: The Hoehn-Yahr stage increased in 14 patients and was unchanged in 12 patients. The 36-item Short-Form Health Survey score (OR 1.079, p = 0.041, 95% CI 1.003-1.161) and the number of steps on the suddenly narrow path (OR 1.605, p = 0.047, 95% CI 1.006 2.56) were related to an increase in the Hoehn-Yahr stage. The number of steps was significantly higher on the suddenly narrowed path (11.3 +/- 3.6) than on a straightly narrowed path (10.1 +/- 3.2) at the time of final follow-up in the 26 patients (p < 0.001). CONCLUSIONS: An increased number of steps associated with FOG, which was elicited by the suddenly narrowed path, might be one predictor of an upgrade of stage in patients with Hoehn-Yahr stage III PD. PMID- 29471293 TI - Neonatal Stress Has a Long-Lasting Sex-Dependent Effect on Anxiety-Like Behavior and Neuronal Morphology in the Prefrontal Cortex and Hippocampus. AB - The long-lasting effects of early stress on brain development have been well studied. Recent evidence indicates that males and females respond differently to the same stressor. We examined the chronic effects of daily maternal separation (MS) on behavior and cerebral morphology in both male and female rats. Cognitive and anxiety-like behaviors were evaluated, and neuroplastic changes in 2 subregions of the prefrontal cortex (dorsal agranular insular cortex [AID] and cingulate cortex [Cg3]) and hippocampus (CA1 and dentate gyrus) were measured in adult male and female rats. The animals were subjected to MS on postnatal day (P) 3-14 for 3 h per day. Cognitive and emotional behaviors were assessed in the object/context mismatch task, elevated plus maze, and locomotor activity test in early adulthood (P87-P95). Anatomical assessments were performed in the prefrontal cortex (i.e., cortical thickness and spine density) and hippocampus (i.e., spine density). Sex-dependent effects were observed. MS increased anxiety related behavior only in males, whereas locomotor activity was higher in females, with no effects on cognition. MS decreased spine density in the AID and increased spine density in the CA1 area in males. Females exhibited an increase in spine density in the Cg3. Our findings confirm previous work that found that MS causes long-term behavioral and anatomical effects, and these effects were dependent on sex and the duration of MS stress. PMID- 29471294 TI - Novel Familial Variant of the Desert Hedgehog Gene: Clinical Findings in Two Sisters with 46,XY Gonadal Dysgenesis or 46,XX Karyotype and Literature Review. AB - BACKGROUND: In humans, Desert Hedgehog (DHH) gene mutations are a very rare cause of 46,XY gonadal dysgenesis (GD), eventually associated with peripheral neuropathy. PATIENTS AND METHODS: Clinical records of 12 patients with 46,XY GD and unknown genetic background were reviewed and a 46,XY woman with peripheral neuropathy was individuated. Her 46,XX sister affected by similar neuropathy was also investigated. Genomic DNA was extracted and DHH exons sequenced and analyzed. A comparative genomic hybridization array was also performed. RESULTS: In both the 46,XY and 46,XX sisters, a homozygous c.554C>A mutation in exon 2 of the DHH gene was found, determining a premature termination codon (p.Ser 185*). Heterozygous consanguineous carrier parents showed neither reproductive problems nor peripheral neuropathy. In the proband and her sister, a 499-kb duplication in 9p22.1 was also found. CONCLUSION: A 46,XY European woman with 46,XY GD and a novel homozygous DHH pathogenic variant is reported, confirming that this gene plays a key role in male gonadal development. Her 46,XX sister, harboring the same mutation, showed normal internal and external female phenotype. Thus, DHH seems not to be involved in the ovarian development pathway or its postpubertal function. Homozygous DHH mutations cause a specific peripheral neuropathy in humans with both 46,XY and 46,XX karyotypes. PMID- 29471295 TI - Higher Failure of Endoscopic Third Ventriculostomy in Infants: The "Distensible" Skull Is the Culprit. AB - The efficacy of endoscopic third ventriculostomy (ETV) in childhood strongly correlates with age. Reasons for the higher failure rate in infants are under debate but the "distensible" head with its immature skull (which would prevent an adequate flow through the ETV and/or a sufficient pressure gradient between the cortical subarachnoid spaces and the venous sinuses) has been suggested as a possible cause. Our evidence of spontaneous conversion of a failed, but always patent, third ventriculostomy into an effective one occurring in a child after maturation of the skull supports this hypothesis.

AB - Ambulatory assessment (AA) is an important tool that promises to minimize retrospective biases while gathering ecologically valid data, including self reports, physiological or biological data, and observed behavior, for example, from daily life experiences. AA is well suited for studying borderline personality disorder (BPD) because it can measure moods and emotion (as well as dynamic mood processes, mood changes, and mood instability), problematic behaviors (including interpersonal conflicts, addictive behaviors, binge and purge episodes, and motoric activity), and problematic cognitions/expectancies/urges (e.g., rejection sensitivity, cravings, and self harm urges) as they occur in daily life. In this article, I review existing AA research on BPD, and I discuss future applications of AA as well as limitations and considerations for future use. PMID- 29471299 TI - The Effect of Allium cepa Extract on Lung Oxidant, Antioxidant, and Immunological Biomarkers in Ovalbumin-Sensitized Rats. AB - OBJECTIVES: To evaluate the effects of Allium cepa (A. cepa) on levels of oxidants, antioxidants, and immunological markers in bronchoalveolar lavage fluids (BALF) of sensitized rats. MATERIALS AND METHODS: Oxidant/antioxidant markers and cytokines in BALF of control rats treated with saline (group C), ovalbumin-sensitized rats (group S), rats treated with 1.25 MUg/mL dexamethasone and 3 doses of A. cepa extract (35, 70, and 140 mg/kg body weight [BW]/day) (S + AC) were investigated. Comparison of the results between groups was performed using analysis of variance with the Tukey-Kramer post hoc test. RESULTS: The oxidant markers nitrogen dioxide (NO2), nitrate (NO3-), and malondialdehyde (MDA), and immunological markers interleukin (IL)-4 and immunoglobulin E (IgE) were significantly higher, but the antioxidant markers superoxide dismutase (SOD), catalase (CAT), thiol, and interferon (IFN)-gamma, and the IFN-gamma/IL-4 ratio were lower in sensitized rats compared to control rats (p < 0.001 to p < 0.01). Compared to group S, the levels of the following markers were significantly lower: NO2, NO3-, and IgE in groups treated with the A. cepa extract, MDA and IL-4 levels in groups treated with 70 and 140 mg/kg BW/day of the A. cepa extract, and all these markers as well as IFN-gamma in rats treated with dexamethasone (p < 0.001 to p < 0.05). However, there were significantly higher levels of SOD and CAT and an increased IFN-gamma/IL-4 ratio (groups treated with 70 and 140 mg/kg BW/day of the A. cepa extract), and levels of thiol and IFN-gamma (group treated with 140 mg/kg BW/day of the A. cepa extract) as well as SOD, CAT, and thiol (dexamethasone-treated group) versus group S (p < 0.00 to p < 0.05). CONCLUSION: A. cepa showed antioxidant and immunomodulatory properties in sensitized rats. PMID- 29471301 TI - Repeated Bioimpedance Measurements Predict Prognosis of Peritoneal Dialysis Patients. AB - BACKGROUND: Fluid overload is a major risk factor for mortality in patients undergoing peritoneal dialysis (PD). However, few studies have investigated the effect of chronic exposure to sustained fluid overload on long-term outcomes. METHOD: A total of 284 prevalent PD patients were included in this prospective study. Repeated multifrequency body composition analysis was performed 12 months apart, and 1-year cumulative chronic fluid overload were used to predict all cause mortality and the risk for transfer to hemodialysis (HD) during the ensuing 15.6 +/- 9.1 months. RESULTS: The prevalence of fluid overload was approximately 27%. Interestingly, a substantial number of hypervolemic patients at first test were persistently hypervolemic at their second test. With this, chronic fluid overload was observed in 18.3% (n = 52). Notably, most of chronic fluid overload patients had diabetes (86.5%), and it was accompanied by concomitant changes in peritoneal membrane characteristics, a higher progression rate to high transporter. The risk of transfer to HD increased 2.8 times in patients with chronic fluid overload than in those without. Also, it significantly increased the risk of mortality (p = 0.038). Surprisingly, subgroup analysis found that patients with euvolemic status at follow-up experienced no mortality despite being in a fluid overload state at baseline. CONCLUSIONS: One-year chronic exposure to fluid overload is a strong independent risk factor for transfer to HD and death in prevalent PD patients. Although the fluid status of most PD patients is not easily changed over time, becoming euvolemic during the entire PD treatment period seems to be very important. PMID- 29471300 TI - Yttrium-90-Ibritumomab Tiuxetan (Zevalin(r)) Radioimmunotherapy after Cytoreduction with ESHAP Chemotherapy in Patients with Relapsed Follicular Non Hodgkin Lymphoma: Final Results of a Phase II Study. AB - BACKGROUND: Radioimmunotherapy (RIT) is effective in treating relapsed/refractory follicular lymphoma (FL), with durable remissions in first-line consolidation. We hypothesized that RIT with ibritumomab tiuxetan (Zevalin(r)) would result in durable remissions by eliminating minimal residual disease after cytoreduction. METHODS: Patients with FL received 2 cycles of ESHAP (etoposide, methylprednisolone, cytarabine, cisplatin) every 28 days, followed by Zevalin 4-6 weeks later if there was no disease progression and bone marrow biopsy showed < 25% involvement. RESULTS: Twenty-eight patients were treated, with a median age of 61 years, median of 3 prior therapies, 49% high-risk disease (Follicular Lymphoma International Prognostic Index, FLIPI), and 39% progressive disease. Three patients did not receive Zevalin due to residual bone marrow involvement. The main toxicities were cytopenias, with 11% febrile neutropenia. The overall response rate (ORR) was 72%, with 45% achieving complete response. With a median follow-up of 73 months, 1-year progression-free survival (PFS) was 38%, and median PFS was 10 months, but median overall survival (OS) was not reached. CONCLUSION: The study did not reach its primary endpoint of a 1-year PFS of 67.3%. Reasons for this could include low accrual, high-risk disease, and inadequate debulking provided by 2 cycles of ESHAP. However, this protocol was associated with tolerable toxicity, high ORR, and high OS. Further studies would optimize debulking and focus on high-risk FL patients. PMID- 29471302 TI - SOCS3 Is Upregulated and Targeted by miR30a-5p in Allergic Rhinitis. AB - BACKGROUND: Suppressor of cytokine signaling 1 (SOCS1) and SOCS3 play important roles in T helper cell differentiation, which is involved with the pathologic mechanisms of allergic rhinitis (AR). The aim of this study was to evaluate the expression of SOCS1 and SOCS3 in AR and find their regulatory microRNAs (miRNAs) to provide a basis for the treatment of AR. METHODS: The expression of SOCS1 and SOCS3 were analyzed by real-time PCR, immunohistochemistry, and Western blot. The correlative regulatory miRNAs were detected by real-time PCR. Luciferase assays and AR mouse model experiments were applied to identify correlative miRNAs that target SOCS3. RESULTS: SOCS1 and SOCS3 mRNA were upregulated in the nasal mucosa and peripheral blood mononuclear cells of AR compared with controls. The expression of SOCS3 protein was significantly increased in the nasal mucosa of AR. The immunohistochemical staining results showed that SOCS3 was similarly localized in the superficial epithelium, submucosal glands, and vascular endothelium in the nasal mucosa of AR subjects and controls. However, SOCS3 protein was especially localized in the inflammatory cells, such as eosinophils, monocytes, and lymphocytes. CONCLUSIONS: SOCS3 was targeted by miR30a- 5p in AR. Further study should be performed to identify the regulatory effect of miR30a-5p in AR, which may provide insights into a new therapeutic strategy.

AB - It is unknown whether dialysis facility staff are aware of the new kidney allocation system implemented in December 2014, which changed how deceased donor kidneys are allocated and waiting time is calculated. U.S. dialysis facilities with low annual waitlisting (<15.2%) were surveyed as part of a large randomized study. Among 653 facilities, 57.9% of staff were aware of the policy change, with medical directors (84.4%) being more aware than social workers (73.3%), facility administrators (53.1%), nurse managers (46.4%), and other staff (43.8%). Targeted education among dialysis facilities with low waitlisting may help extend the reach of the new policy.

AB - We evaluated the in vivo efficacy of humanized exposures of cefiderocol, a novel siderophore cephalosporin, against a test panel of P. aeruginosa (PSA) previously shown to develop resistance to 2 preclinical candidate siderophores (MB-1 and SMC 3176). In the thigh infection model, the PSA bacterial density in untreated controls grew from 5.54 +/- 0.23 to 8.68 +/- 0.57 log10 CFU over 24 h. The humanized cefiderocol exposure resulted in >1 log10 CFU reduction in all 8 isolates, while MB-1 and SMC-3176 exhibited variable activity similar to that previously reported. Humanized exposures of cefepime and levofloxacin, acting as positive antimicrobial controls displayed activity consistent with that of the bacterial phenotypic susceptibility profiles. Cefiderocol manifested in vivo efficacy against all PSA isolates including those resistant to cefepime and levofloxacin in contrast to its predecessor siderophore compounds. These preclinical data are supportive of further evaluation of cefiderocol in the treatment of P. aeruginosa.

PMID- 29471308 TI - Reporting guidelines for oncology research: helping to maximise the impact of your research. AB - Many reports of health research omit important information needed to assess their methodological robustness and clinical relevance. Without clear and complete reporting, it is not possible to identify flaws or biases, reproduce successful interventions, or use the findings in systematic reviews or meta-analyses. The EQUATOR Network (http://www.equator-network.org/) promotes responsible reporting and the use of reporting guidelines to improve the accuracy, completeness, and transparency of health research. EQUATOR supports researchers by providing online resources and training. EQUATOR Oncology, a project funded by Cancer Research UK, aims to support cancer researchers reporting their research through the provision of online resources. In this article, our objective is to highlight reporting issues related to oncology research publications and to introduce reporting guidelines that are designed to aid high-quality reporting. We describe generic reporting guidelines for the main study types, and explain how these guidelines should and should not be used. We also describe 37 oncology-specific reporting guidelines, covering different clinical areas (e.g., haematology or urology) and sections of the report (e.g., methods or study characteristics); most of these are little-used. We also provide some background information on EQUATOR Oncology, which focuses on addressing the reporting needs of the oncology research community. PMID- 29471309 TI - The role of the diet in tooth wear. AB - An acidic diet has been associated with erosive tooth wear. However, some people who consume dietary acids develop erosive tooth wear and some do not. This review paper provides an overview of the risk factors of dietary acid consumption which increase the likelihood of developing severe erosive tooth wear. Increased frequency of dietary acid consumption, particularly between meals appears to be the predominant risk factor. However, habitually drinking acidic drinks by sipping them slowly or swishing, rinsing or holding acidic drinks in the mouth before swallowing will also increase risk of progression. Consuming fruit over long time periods at a single sitting and dietary acids being served at increased temperatures have also been implicated. Additions of fruit or fruit flavourings to drinks and regular consumption of vinegars, pickles, acidic medications or acidic sugar-free sweets are potential hidden risk factors that should be discussed with patients at risk of erosive tooth wear progression. Behaviour change is difficult to achieve but specific, targeted behavioural interventions and offering alternatives may increase success.

PMID- 29471310 TI - Age-related reduction of trunk muscle torque and prevalence of trunk sarcopenia in community-dwelling elderly: Validity of a portable trunk muscle torque measurement instrument and its application to a large sample cohort study. AB - Trunk muscle weakness and imbalance are risk factors for postural instability, low back pain, and poor postoperative outcomes. The association between trunk muscle strength and aging is poorly understood, and establishing normal reference values is difficult. We aimed to establish the validity of a novel portable trunk muscle torque measurement instrument (PTMI). We then estimated reference data for healthy young adults and elucidated age-related weakness in trunk muscle strength. Twenty-four university students were enrolled to validate values for PTMI, and 816 volunteers from the general population who were recruited to the Iwaki Health Promotion Project were included to estimate reference data for trunk muscle strength. Trunk flexion and extension torque were measured with PTMI and KinCom, and interclass correlation coefficients (ICC) were estimated to evaluate the reliability of PTMI values. Furthermore, from the young adult reference, the age-related reduction in trunk muscle torque and the prevalence of sarcopenia among age-sex groups were estimated. The ICC in flexion and extension torque were 0.807 (p<0.001) and 0.789 (p<0.001), respectively. The prevalence of sarcopenia increased with age, and the prevalence due to flexion torque was double that of extension torque. Flexion torque decreased significantly after 60 years of age, and extension torque decreased after 70 years of age. In males over age 80, trunk muscle torque decreased to 49.1% in flexion and 63.5% in extension. In females over age 80, trunk muscle torque decreased to 60.7% in flexion and 68.4% in extension. The validity of PTMI was confirmed by correlation with KinCom. PTMI produced reference data for healthy young adults, and demonstrated age-related reduction in trunk muscle torque. Trunk sarcopenia progressed with aging, and the loss of flexion torque began earlier than extension torque. At age 80, trunk muscle torque had decreased 60% compared with healthy young adults. PMID- 29471316 TI - Influence of Prior Knowledge of Human Papillomavirus Status on the Performance of Cytology Screening. AB - Objectives: This study aimed to evaluate the influence of prior knowledge of human papillomavirus (HPV) status in cervical cytopathology readings. Methods: Participants comprised 2,376 women who underwent parallel cytology and HPV-DNA testing. Smears were read twice by the same team, first with previous knowledge of HPV-DNA status. Results: Overall, 239 (10.2%) smears had their cytology classification altered by the HPV-informed review. Cytology readings with prior knowledge of the HPV status revealed 10.5% of abnormal smears (atypical squamous cells of undetermined significance or higher), while without prior knowledge, this rate dropped to 7.6%. When HPV status was informed, a significant increase in all categories of altered smears was observed. Cytology with prior knowledge of HPV status detected more cervical intraepithelial neoplasia grade 2 or higher (CIN 2+) compared with blinded: 86.7% vs 60.0%. Conclusions: Our data indicate that cytology interpreted with prior knowledge of the HPV status provides higher sensitivity for CIN 2+ lesions while marginally reducing the overall specificity compared with HPV status blinded cytology. PMID- 29471318 TI - Family physician awareness of Charles Bonnet syndrome. AB - Background: Charles Bonnet syndrome is characterized by formed visual hallucinations in individuals with vision loss. It is reported that one in five older adults with vision loss suffer from Charles Bonnet syndrome and the suspected lack of awareness amongst family physicians may lead to misdiagnosis and inappropriate treatment. Objective: To assess Canadian family physicians' awareness of Charles Bonnet syndrome. Methods: We conducted a national perception and practices survey of family physicians across Canada to assess (i) the level of awareness of Charles Bonnet syndrome amongst family physicians; (ii) the frequency of family physicians' encounters with patients with visual hallucinations and (iii) management strategies and referral patterns for patients with Charles Bonnet syndrome presenting to family physicians. Results: Four hundred and ninety-nine family physicians across Canada answered at least one question on the survey. 54.7% indicated they were not at all aware and 19.7% indicated they were slightly aware of Charles Bonnet syndrome. 72.8% of physicians had patients present with visual hallucinations once a year or less often. The frequency of patients seen in practice with visual hallucinations is significantly associated with awareness by physicians of Charles Bonnet syndrome (beta = 0.501, t(388) = 5.59, P < 0.001). Of those who encountered patients with visual hallucinations, the majority of respondents (77.4%) provided counselling or education to the patient. Conclusion: There is a great lack of knowledge about Charles Bonnet syndrome among family physicians. Awareness of Charles Bonnet syndrome is critical to appropriate diagnosis, assessment and treatment of this condition and to reassure patients that they are not suffering from a mental disorder.

AB - Agricultural practices affect arthropod communities and, therefore, have the potential to influence the activities of arthropods. We evaluated the effect of cover crop species and termination timing on the activity of ground-dwelling predatory arthropods in a corn-soybean-wheat rotation in transition to organic production in Pennsylvania, United States. We compared two cover crop treatments: 1) hairy vetch (Vicia villosa Roth) planted together with triticale (*Triticosecale Wittmack) after wheat harvest, and 2) cereal rye (Secale cereale Linnaeus) planted after corn harvest. We terminated the cover crops in the spring with a roller-crimper on three dates (early, middle, and late) based on cover crop phenology and standard practices for cash crop planting in our area. We characterized the ground-dwelling arthropod community using pitfall traps and assessed relative predation using sentinel assays with live greater waxworm larvae (Galleria mellonella Fabricius). The activity density of predatory arthropods was significantly higher in the hairy vetch and triticale treatments than in cereal rye treatments. Hairy vetch and triticale favored the predator groups Araneae, Opiliones, Staphylinidae, and Carabidae. Specific taxa were associated with cover crop condition (e.g., live or dead) and termination dates. Certain variables were positively or negatively associated with the relative predation on sentinel prey, depending on cover crop treatment and stage, including the presence of predatory arthropods and various habitat measurements. Our results suggest that management of a cover crop by roller-crimper at specific times in the growing season affects predator activity density and community composition. Terminating cover crops with a roller-crimper can conserve generalist predators. PMID- 29471321 TI - Overexpression of heparanase in mice promoted megakaryopoiesis. AB - Heparanase, an endo-glucuronidase that specifically cleaves heparan sulfate (HS), is upregulated in several pathological conditions. In this study, we aimed to find a correlation of heparanase expression and platelets production. In the transgenic mice overexpressing human heparanase (Hpa-tg), hematological analysis of blood samples revealed a significantly higher number of platelets in comparison with wild-type (Ctr) mice, while no significant difference was found in leukocytes and red blood cell number between the two groups. Total number of thiazole orange positive platelets was increased in Hpa-tg vs. Ctr blood, reflecting a higher rate of platelets production. Concomitantly, megakaryocytes from Hpa-tg mice produced more and shorter HS fragments that were shed into the medium. Further, thrombopoietin (TPO) level was elevated in the liver and plasma of Hpa-tg mice. Together, the data indicate that heparanase expression promoted megakaryopoiesis, which may be through upregulated expression of TPO and direct effect of released HS fragments expressed in the megakaryocytes. PMID- 29471322 TI - Whole-body nitrogen utilization and tissue protein and casein synthesis in lactating primiparous sows fed low- and high-protein diets. AB - Twenty-eight lactating Yorkshire and Yorkshire * Landrace primiparous sows were used to test the hypothesis that feeding a diet with reduced CP concentration and supplemented with crystalline AA (CAA) does not decrease milk protein yield and litter growth but improves apparent N utilization for milk protein production. Sows were assigned to 1 of 2 dietary treatments: 1) control (CON; 16.2% CP; analyzed content) or 2) low CP with CAA to meet estimated requirements of limiting AA (LCP; 12.7% CP) over a 17-d lactation period. A N balance was conducted for each sow between days 13 and 17 of lactation. On day 17, a 12-h primed continuous infusion of l-[ring-2H5]-Phe was conducted on 12 sows (n = 6) with serial blood and milk sampling to determine plasma AA concentrations and Phe enrichment, and milk casein synthesis, respectively. Thereafter, sows were sacrificed and tissues were collected to determine tissue protein fractional synthesis rates (FSR). Litter growth rate and milk composition did not differ. Sows fed the LCP diet had reduced N intake (122.7 vs. 153.2 g/d; P < 0.001) and maternal N retention (13.5 vs. 24.6 g/d; P < 0.05) and greater apparent efficiency of using dietary N intake for milk production (85.1% vs. 67.5%; P < 0.001). On day 17 of lactation, all plasma essential AA concentrations exhibited a quartic relationship over time relative to consumption of a meal, where peaks occurred at approximately 1- and 4-h postprandial (P < 0.05). Protein FSR in liver, LM, gastrocnemius muscle, mammary gland, and in milk caseins did not differ between treatments. Feeding primiparous sows with a diet containing 12.7% CP and supplemented with CAA to meet the limiting AA requirements did not reduce milk protein yield or piglet growth rate and increased the apparent utilization of dietary N, Arg, Leu, Phe+Tyr, and Trp for milk protein production. The improved apparent utilization of N and AA appears to be related exclusively to a reduction in N and AA intake. PMID- 29471323 TI - What's to Be Done About Laboratory Quality? Process Indicators, Laboratory Stewardship, the Outcomes Problem, Risk Assessment, and Economic Value: Responding to Contemporary Global Challenges. AB - Objectives: For 50 years, structure, process, and outcomes measures have assessed health care quality. For clinical laboratories, structural quality has generally been assessed by inspection. For assessing process, quality indicators (QIs), statistical monitors of steps in the clinical laboratory total testing, have proliferated across the globe. Connections between structural and process laboratory measures and patient outcomes, however, have rarely been demonstrated. Methods: To inform further development of clinical laboratory quality systems, we conducted a selective but worldwide review of publications on clinical laboratory quality assessment. Results: Some QIs, like seven generic College of American Pathologists Q-Tracks monitors, have demonstrated significant process improvement; other measures have uncovered critical opportunities to improve test selection and result management. The College of Pathologists of Australasia Key Indicator Monitoring and Management System has deployed risk calculations, introduced from failure mode effects analysis, as surrogate measures for outcomes. Showing economic value from clinical laboratory testing quality is a challenge. Conclusions: Clinical laboratories should converge on fewer (7-14) rather than more (21-35) process monitors; monitors should cover all steps of the testing process under laboratory control and include especially high-risk specimen-quality QIs. Clinical laboratory stewardship, the combination of education interventions among clinician test orderers and report consumers with revision of test order formats and result reporting schemes, improves test ordering, but improving result reception is more difficult. Risk calculation reorders the importance of quality monitors by balancing three probabilities: defect frequency, weight of potential harm, and detection difficulty. The triple approach of (1) a more focused suite of generic consensus quality indicators, (2) more active clinical laboratory testing stewardship, and (3) integration of formal risk assessment, rather than competing with economic value, enhances it. PMID- 29471325 TI - Dual Stain With SATB2 and CK20/Villin Is Useful to Distinguish Colorectal Carcinomas From Other Tumors. AB - Objectives: Small sample size limits the number of immunostains that may be attempted in colorectal carcinoma (CRC) biopsy specimens. We investigated the utility of dual stain with special AT-rich sequence binding protein 2 (SATB2) or caudal-type homeobox 2 (CDX2) and cytokeratin 20 (CK20) or villin in identifying CRC. Methods: Tissue microarrays with 222 CRCs and 375 other carcinomas were built. Dual stain was performed pairing nuclear stains CDX2 or SATB2 with CK20 or villin. Results: All four single stains showed excellent sensitivity (93%-99%) but variable specificity (56%-88%) for CRC. All four dual stains also showed excellent sensitivity (90%-96%) while much improved specificity (88%-98%) compared with single stains. SATB2 dual stain (with CK20 or villin) showed a higher specificity than CDX2 dual stain (with CK20 or villin) with a comparable sensitivity. Conclusions: SATB2 dual stain shows the greatest potential clinical utility in identifying CRC and is superior to CDX2 dual stain. More important, SATB2 dual stain could be helpful for specimens with limited tissues or those having a nonclassic staining pattern. PMID- 29471324 TI - Effectiveness of Practices to Support Appropriate Laboratory Test Utilization: A Laboratory Medicine Best Practices Systematic Review and Meta-Analysis. AB - Objectives: To evaluate the effectiveness of practices used to support appropriate clinical laboratory test utilization. Methods: This review followed the Centers for Disease Control and Prevention (CDC) Laboratory Medicine Best Practices A6 cycle method. Eligible studies assessed one of the following practices for effect on outcomes relating to over- or underutilization: computerized provider order entry (CPOE), clinical decision support systems/tools (CDSS/CDST), education, feedback, test review, reflex testing, laboratory test utilization (LTU) teams, and any combination of these practices. Eligible outcomes included intermediate, systems outcomes (eg, number of tests ordered/performed and cost of tests), as well as patient-related outcomes (eg, length of hospital stay, readmission rates, morbidity, and mortality). Results: Eighty-three studies met inclusion criteria. Fifty-one of these studies could be meta-analyzed. Strength of evidence ratings for each practice ranged from high to insufficient. Conclusion: Practice recommendations are made for CPOE (specifically, modifications to existing CPOE), reflex testing, and combined practices. No recommendation for or against could be made for CDSS/CDST, education, feedback, test review, and LTU. Findings from this review serve to inform guidance for future studies. PMID- 29471326 TI - Urinary Cytomegalovirus Shedding in the United States: The National Health and Nutrition Examination Surveys, 1999-2004. AB - Background: There are no data on the prevalence of cytomegalovirus (CMV) shedding from a representative sample of the US population. This information is critical for understanding and preventing CMV. Methods: We tested urine specimens from CMV immunoglobulin (Ig) G-positive participants aged 6-49 years in 3 racial/ethnic groups from the National Health and Nutrition Examination Surveys 1999-2004 for the presence of CMV DNA using real-time polymerase chain reaction assay. We examined the association of sociodemographic characteristics with shedding prevalence and viral loads. Results: Among 6828 CMV IgG-positive participants tested, 537 had CMV DNA detected in urine-a shedding prevalence of 9.70%. Among persons aged 6-49 years, shedding prevalence was 3.83%. The prevalence of urinary shedding was inversely associated with increasing age (26.60%, 6.50%, and 3.45% in CMV IgG-positive participants aged 6-11, 12-19, and 20-49 years, respectively; P < .001 for trend test and pairwise comparisons). Urinary viral load also decreased significantly with age (mean, 2.97, 2.69, and 2.43 log10 copies/mL in those age groups, respectively; P < .001 for trend test and pairwise comparisons). Conclusions: Urinary CMV shedding and viral loads decreased dramatically with age, likely reflecting higher rates of primary CMV infection and longer duration of shedding in younger individuals. The findings demonstrate that children aged 6-11 years continue to shed CMV at higher rates and viral loads than adolescents and adults and thus may still be an important source for CMV transmission. PMID- 29471327 TI - Alachlor Use and Cancer Incidence in the Agricultural Health Study: An Updated Analysis. AB - Background: The herbicide alachlor has been widely used in US agriculture since its introduction in 1969. Experimental animal studies show that alachlor causes tumors in vivo; however, few epidemiologic studies have examined associations with human cancer risk. We evaluated alachlor use and cancer incidence in the Agricultural Health Study, updating an earlier analysis that suggested associations with lymphohematopoietic cancers with an additional 540 142 person years of follow-up and 5113 cancer cases. Methods: Pesticide applicators in Iowa and North Carolina reported lifetime alachlor use at enrollment (1993-1997) and follow-up (1999-2005). Exposure was characterized by cumulative intensity weighted days. We estimated relative risks (RRs) and 95% confidence intervals (CIs) using Poisson regression for incident cancers from enrollment through 2012(NC)/2013(IA). Models adjusted for age, tobacco, alcohol, and other pesticides. All statistical tests are two-sided. Results: Among 49 685 applicators, 25 640 (51.6%) used alachlor, with 3534 alachlor-exposed cancers. The relative risks of laryngeal cancer (nexposed = 34) increased in the second (RR = 4.68, 95% CI = 1.95 to 11.23), third (RR = 6.04, 95% CI = 2.44 to 14.99), and fourth quartiles (RR = 7.10, 95% CI = 2.58 to 19.53) of intensity-weighted days of use compared with no use (Ptrend = .001). Risk of myeloid leukemia was elevated, though not statistically significantly so, in the fourth quartile of intensity-weighted days of use (RR = 1.82, 95% CI = 0.85 to 3.87, Ptrend = .17). Conclusions: We observed a strong positive association with use of alachlor and laryngeal cancer and a weaker association with myeloid leukemia. The strength and robustness of the association with laryngeal cancer suggests that long-term occupational exposure to alachlor may be a risk factor for laryngeal cancer. This first report requires confirmation. PMID- 29471328 TI - A member of the Roseobacter clade, Octadecabacter sp., is the dominant symbiont in the brittle star Amphipholis squamata. AB - Symbiotic associations with subcuticular bacteria (SCB) have been identified and studied in many echinoderms, including the SCB of the brooding brittle star, Amphipholis squamata. Previous studies on the SCB of A. squamata placed the isolated bacterium, designated as AS1, in the genus Vibrio (Gammaproteobacteria), but subsequent studies suggested that the SCB of echinoderms belong to the Alphaproteobacteria. This study examines the taxonomic composition of SCB associated with A. squamata from the Northwest Atlantic using the 16S rRNA gene and next generation sequencing. Results show the presence of a single dominant bacterial type, within the Roseobacter clade, family Rhodobacteraceae, which composes 70%-80% of the A. squamata microbiome. These Rhodobacteraceae sequences were identified as members of the genus Octadecabacter. Additionally, the original isolate, AS1, from the brittle star A. squamata also belongs in the genus Octadecabacter based on Sanger sequencing of cloned 16S rRNA gene sequences. By comparison, adjacent seawater and sediment porewater communities were significantly more diverse, hosting bacteria in the phyla Proteobacteria, Bacteroidetes, Cyanobacteria, Verrucomicrobia and Actinobacteria. Thus, a distinct SCB community is present in A. squamata that is dominated by a member of the genus Octadecabacter and is identical to the original isolate, AS1, from this brittle star. PMID- 29471329 TI - Effects of Varenicline, Depressive Symptoms, and Region of Enrollment on Smoking Cessation in Depressed Smokers. AB - Introduction: Despite effective treatments, relapse to smoking remains a vexing global health problem. One predictor of relapse is depressive symptoms. Medications such as varenicline reduce withdrawal-related symptoms of depression, reducing relapse. This study examined whether varenicline moderated the effect of depressive symptoms on relapse, and whether this varied by region of enrollment. Methods: Adult smokers (n=525; 37% male) with past or current, stable major depressive disorder recruited from US (n=255), and European (n=270) sites participated in a randomized, double-blind cessation treatment trial including 12 weeks of varenicline or placebo, with 40-week non-treatment follow-up. Results: Longitudinal and binary logistic regression were used to model the probability of sustained abstinence by end of treatment and point-prevalence abstinence in follow-up. The association between depression symptoms and abstinence was moderated by intervention group at end of treatment, and by region during follow up: more severe symptoms were associated with end-of-treatment relapse for placebo (OR = 0.91, p=.003), but not varenicline (OR = 0.99, p = .568). During follow-up, increased symptoms of depression predicted greater likelihood of smoking for European (p=.009) but not US participants. Europeans were more likely to be abstinent for both outcomes (p<.01). Conclusions: These results extend studies demonstrating varenicline is associated with less withdrawal-related depression, and suggest it aids cessation even in smokers with depressive symptoms. Findings also suggest regional differences in the relationship between depressive symptoms and cessation that may be related to differences in prevalence. Implications: This study indicates varenicline may aid cessation partially by reducing withdrawal-related symptoms of depression. It also suggests that the impact of depressive symptoms on cessation varies regionally, and that this variation may be related to differences in smoking prevalence. PMID- 29471330 TI - Converging and diverging needs between patients and providers who are collecting and using patient-generated health data: an integrative review. AB - Objective: This integrative review identifies convergent and divergent areas of need for collecting and using patient-generated health data (PGHD) identified by patients and providers (i.e., physicians, nurses, advanced practice nurses, physician assistants, and dietitians). Methods: A systematic search of 9 scholarly databases targeted peer-reviewed studies published after 2010 that reported patients' and/or providers' needs for incorporating PGHD in clinical care. The studies were assessed for quality and bias with the Mixed-Methods Appraisal Tool. The results section of each article was coded to themes inductively developed to categorize patient and provider needs. Distinct claims were extracted and areas of convergence and divergence identified. Results: Eleven studies met inclusion criteria. All had moderate to low risk of bias. Three themes (clinical, logistic, and technological needs), and 13 subthemes emerged. Forty-eight claims were extracted. Four were divergent and twenty were convergent. The remainder was discussed by only patients or only providers. Conclusion: As momentum gains for integrating PGHD into clinical care, this analysis of primary source data is critical to understanding the requirements of the 2 groups directly involved in collection and use of PGHD. PMID- 29471332 TI - Mycobacterium tuberculosis-Infected Hematopoietic Stem and Progenitor Cells Unable to Express Inducible Nitric Oxide Synthase Propagate Tuberculosis in Mice. AB - Persistence of Mycobacterium tuberculosis within human bone marrow stem cells has been identified as a potential bacterial niche during latent tuberculosis. Using a murine model of tuberculosis, we show here that bone marrow stem and progenitor cells containing M. tuberculosis propagated tuberculosis when transferred to naive mice, given that both transferred cells and recipient mice were unable to express inducible nitric oxide synthase, which mediates killing of intracellular bacteria via nitric oxide. Our findings suggest that bone marrow stem and progenitor cells containing M. tuberculosis propagate hallmarks of disease if nitric oxide-mediated killing of bacteria is defective. PMID- 29471331 TI - Cross Cultural Validation and Extension of the Clinical Assessment Interview for Negative Symptoms (CAINS) in the Chinese Context: Evidence from a Spectrum Perspective. AB - The Clinical Assessment Interview for Negative Symptoms (CAINS) was designed in accordance with the recent theory and research in social affective neuroscience and to address the psychometric and conceptual limitations of other instruments assessing negative symptoms. The present study aimed to provide a large-scale validation of the CAINS in China and examine its applicability and validity evidence across the schizophrenia spectrum. Using confirmatory factor analysis, our results replicated the original findings in the US development samples that the CAINS possesses a stable 2-factor structure, namely "motivation/pleasure" and "expression". We also found significant correlations between the CAINS and other negative symptom measures. The CAINS demonstrated good discriminant validity in differentiating negative symptoms in people with schizophrenia, nonpsychotic first-degree relatives and people with social anhedonia. People with schizophrenia exhibited significantly higher CAINS subscale scores than first degree relatives and healthy controls. In addition, first-degree relatives had higher "motivation/pleasure" scores than healthy controls. The "motivation/pleasure" subscale scores of individuals with social anhedonia were also significantly higher than healthy controls.

PMID- 29471334 TI - Progress toward elimination of onchocerciasis in the Americas. AB - The Onchocerciasis Elimination Program for the Americas (OEPA) is a regional initiative and international partnership that has made considerable progress toward its goal since it was launched in 1993. Its strategy is based on mass drug administration of ivermectin (Mectizan, donated by MSD, also known as Merck & Co., Inc., Kenilworth, NJ, USA), twice or four times per year, with at least 85% coverage of eligible populations. From 1989 to 2016, 11 741 276 ivermectin treatments have been given in the Americas, eliminating transmission in 11 of 13 foci. The OEPA's success has had a great influence on programs in Africa, especially Sudan and Uganda, which moved from a control to an elimination strategy in 2006 and 2007, respectively. The successes in the Americas have also greatly influenced WHO guidelines for onchocerciasis transmission elimination. With four of the six originally endemic American countries now WHO verified as having eliminated onchocerciasis transmission, and 95% of ivermectin treatments in the region halted, the regional focus is now on the remaining active transmission zone, called the Yanomami Area, on the border between Venezuela and Brazil. Both countries have difficult political climates that hinder the elimination task in this remote and relatively neglected region. As with other elimination efforts, 'the final inch' is often the most difficult task of all. PMID- 29471335 TI - After 70 years of fighting an age-old scourge, onchocerciasis in Uganda, the end is in sight. AB - Onchocerciasis causes severe itching, serious skin disease and ocular damage leading to visual impairment or permanent blindness. It is associated with hanging groin, epilepsy, Nakalanga dwarfism and, most recently, nodding disease. This disease affected communities in 17 transmission foci in 37 districts of Uganda, where about 6.7 million people are once at risk. The efforts against onchocerciasis in Uganda commenced in the late 1940s, when vector control was launched using dichlorodiphenyltrichloroethane; by 1973, Simulium damnosum had been eliminated in the Victoria focus. Success outside of the Victoria focus was short-lived due to changes in government priorities and the political upheavals of the 1970s and 1980s. With the return of political stability, annual treatment with ivermectin through mass drug administration was launched in the early 1990s. Control of the disease has been successful, but there has been failure in interrupting transmission after more than 15 years. In 2007 Uganda launched a nationwide transmission elimination policy based on twice-per-year treatment and vector control/elimination, with a goal of eliminating river blindness nationwide by 2020. By 2017, 1 157 303 people from six foci had been freed from river blindness. This is the largest population ever declared free under World Health Organization elimination guidelines, providing evidence that elimination of river blindness in Africa is possible. PMID- 29471336 TI - Diagnostics for onchocerciasis in the era of elimination. AB - In the past few years, efforts to eliminate onchocerciasis from Africa have intensified. These efforts are primarily based on the mass distribution of the anti-helminthic drug MectizanTM (ivermectin). This program has led to the development of new guidelines by the World Health Organization for the verification that transmission has been suppressed and eventually eliminated. The requirements of diagnostic tools for this purpose differ in many ways from tests used to diagnose infection in individuals. In this review, we summarize the progress that has been made to identify diagnostics that meet the specialized requirements needed to verify onchocerciasis elimination, discuss why these tests were selected and summarize the needs that still exist to complete the arsenal of diagnostic tools that will be useful as the goal of elimination is achieved. PMID- 29471337 TI - The role of national committees in eliminating onchocerciasis. AB - National onchocerciasis elimination committees (NOECs) serve to help ministries of health complete the pathway to successful verification of elimination of onchocerciasis (river blindness), as outlined in the 2016 World Health Organization guidelines. These guidelines, however, only take effect when the country believes it has reached a point that elimination can be demonstrated, and do not address the preceding milestones. Therefore, NOECs can be of great help with guiding and tailoring earlier planning, programming and assessments to empower national programs to aggressively move toward their countries' elimination goals. In this article, we provide suggestions for organizing NOECs and examples of four such committees that have successfully operated in Africa and the Americas. PMID- 29471338 TI - Transitioning from river blindness control to elimination: steps toward stopping treatment. AB - The transition from onchocerciasis control to elimination requires country programmes to rethink their approach to a variety of activities as they move from addressing morbidity to addressing transmission of the parasite. Although the 2016 WHO guidelines provide extensive recommendations, it was beyond the scope of the document to provide guidance on all aspects of the transition. This paper will discuss some of the important issues that programmes are grappling with as they transition to elimination and provide some potential approaches that programmes can use to address them. Although there are some data to support some aspects of the suggested approaches, operational research will be needed to generate data to support these approaches further and to determine how programmes could best tailor them to their own unique epidemiological challenges. Good communication between the national programmes and the broader global programme will facilitate the clear articulation of programmatic challenges and the development of the evidence to support programme decision-making. PMID- 29471339 TI - The role of the NGDO Coordination Group for the Elimination of Onchocerciasis. AB - The NGDO Coordination Group for the Control of Onchocerciasis was launched in 1992, and with the paradigm shift from control of disease to elimination of onchocerciasis transmission, the Group shifted its orientation to that new paradigm in 2013. It also changed its name, replacing 'control' with 'elimination.' In doing so, the Group has repositioned itself to build on the successes of the past to finish the job it began over 25 years ago. PMID- 29471340 TI - Operationalization of the test and not treat strategy to accelerate the elimination of onchocerciasis and lymphatic filariasis in Central Africa. AB - After 30 years of treatment with Mectizan (ivermectin), cutaneous and ocular complications of Onchocerca volvulus infection are now scarce in endemic communities. Indeed, transmission has been interrupted and the O. volvulus- associated disease has disappeared in some African foci. Despite this success, onchocerciasis elimination in Loa loa co-endemic areas is still constrained by severe adverse events (SAEs) occurring after ivermectin treatment in some individuals harbouring very high L. loa microfilaremia. One approach towards the prevention of these SAEs is to identify individuals with high L. loa microfilaremia and exclude them from ivermectin treatment. The development of the LoaScope has provided the tool that underlies this test and not treat (TaNT) strategy. The first successful TaNT campaign was conducted in a L. loa highly endemic focus in Cameroon in 2015 without any SAEs. To accomplish this within a research setting, 60 people were deployed for this campaign, making this 'research' strategy not sustainable from a cost perspective. We describe here a way of reducing the cost of the TaNT strategy with a smaller team (three people) selected within affected communities. We also suggest the organization of a TaNT campaign in affected countries. PMID- 29471341 TI - Onchocerciasis: shifting the target from control to elimination requires a new first-step-elimination mapping. AB - The meaning of 'mapping' in relation to onchocerciasis has changed at least three times over the past 50 years as the programmatic goals and the assessment tools have changed. With the current goal being global elimination of Onchocerca volvulus (OV), all areas where OV might currently be transmitted and where mass drug administration (MDA) with ivermectin treatment has not been delivered previously must now be identified by careful, detailed 'elimination mapping' as either OV endemic or not, so that appropriate programmatic targets can be established. New tools and strategies for such elimination mapping have become available, though ongoing studies must still be completed to define agreed upon optimal diagnostic evaluation units, sampling strategies and serologic tools. With detailed guidance and technical support from the World Health Organization and with implementation and financial support from their global partners, the OV endemic countries of Africa can soon complete their elimination mapping and then continue with MDA programmes to progressively achieve the same success in OV elimination as that already achieved by the growing list of formerly OV-endemic countries in the Americas. PMID- 29471343 TI - Onchocerciasis in Yemen: moving forward towards an elimination program. AB - The onchocerciasis focus in Yemen has been known for many years as an endemic area with unique characteristics, notably the atypical and most severe form of onchodermatitis, known as sowda or reactive onchodermatitis (ROD). The national effort to control the disease began in 1992 as an individual case treatment program by administering ivermectin to those presenting with ROD. The challenging geography of the endemic area and the current political and military unrest both underscore a need for special approaches when attempting to eliminate onchocerciasis from this country. An assessment of the national situation regarding this disease was carried out in 2011-2013 aimed at defining the best approach for moving from individual clinical case treatment to elimination of transmission. The history of the control efforts and the current status of the disease are reviewed and the essential changes needed to a mass drug administration (MDA) approach are identified as the national program addresses elimination. Yemen, despite the current troubles, has shown that it can successfully implement MDA programs despite many difficulties and therefore should be supported in its efforts towards countrywide elimination of this infection; however, success will need renewed national and international efforts. PMID- 29471342 TI - Alternative treatment strategies to accelerate the elimination of onchocerciasis. AB - The use of alternative (or complementary) treatment strategies (ATSs) i.e. differing from annual community-directed treatment with ivermectin (CDTI) is required in some African foci to eliminate onchocerciasis by 2025. ATSs include vector control, biannual or pluriannual CDTI, better timing of CDTI, community directed treatment with combinations of currently available anthelminthics or new drugs, and 'test-and-treat' (TNT) strategies requiring diagnosis of infection and/or contraindications to treatment for decisions on who to treat with what regimen. Two TNT strategies can be considered. Loa-first TNT, designed for loiasis-endemic areas and currently being evaluated using a rapid test (LoaScope), consists of identifying individuals with levels of Loa microfilaremia associated with a risk of post-ivermectin severe adverse events to exclude them from ivermectin treatment and in treating the rest (usually >97%) of the population safely. Oncho-first TNT consists of testing community members for onchocerciasis before giving treatment (currently ivermectin or doxycycline) to those who are infected. The choice of the ATS depends on the prevalences and intensities of infection with Onchocerca volvulus and Loa loa and on the relative cost-effectiveness of the strategies for the given epidemiological situation. Modelling can help select the optimal strategies, but field evaluations to determine the relative cost-effectiveness are urgently needed. PMID- 29471344 TI - Cross-border issues: an important component of onchocerciasis elimination programmes. AB - Endemic areas that involve national or local borders present an important challenge to the success of elimination of onchocerciasis; such cross-border endemic foci require special attention to ensure that programme activities are unified. It is vital that national programmes and the committees responsible for the oversight of progress towards elimination are aware and address such issues in their current planning and programmatic activities. Although international borders that intersect endemic zones present the biggest challenge, intracountry borders (such as between administrative districts or loiasis endemic and non loiasis areas) can also pose problems. The recent change in the onchocerciasis programme from disease control to transmission interruption, given the historical lack of treatment in hypo-endemic areas, may have increased the already relatively high number of cross-national scenarios in Africa. It is vital that all national programmes address the issue of any cross-border endemic areas as a matter of urgency and include this important issue in their elimination plans. PMID- 29471345 TI - Establishing quality assured (QA) laboratory support for onchocerciasis elimination in Africa. AB - An essential component in achieving accepted successful elimination of a disease or a pathogen involves the acquisition of quality-assured (QA) data that ultimately define the absence of infection or transmission in previously endemic areas. The acquisition of these essential data, in the case of onchocerciasis elimination, requires strong laboratory support for both testing and continuing evaluation/validation of the tools used for the required diagnostic and epidemiology procedures. There is also a need for standardization of the laboratory-based and field-based assays used across the onchocerciasis-endemic countries as well as continuing technical, fiscal and logistical support for laboratory activities. To achieve these needs, it is proposed to build on the existing onchocerciasis programme laboratory activities in the endemic areas by expanding these to include additional laboratories as referral services organized on a regional basis to support the needs of endemic countries. Included in these plans are the development of quality assurance mechanisms, supply chain procedures and standardization of protocols for the basic assays needed for both national onchocerciasis elimination programme surveys and supporting research activities. Such an entity could then include quality-assured testing for other neglected tropical diseases. PMID- 29471346 TI - Refocusing vector assessment towards the elimination of onchocerciasis from Africa: a review of the current status in selected countries. AB - Measures to control onchocerciasis have been in place for well over 30 years. Recently, programs have turned from disease control towards transmission elimination. The absence of infective larvae in the black fly Simulium sp. vector is central to defining elimination, and assessments of infectivity by O150 polymerase chain reaction in the vector not only provide valuable information to programs, but are also required for verification of elimination. The status of transmission in black flies was assessed in five countries in the African region during 2014 and 2015. Several of these countries were evaluated because of promising results from epidemiological studies in humans. No infective flies were found in two countries. Infective flies were found in the other three, despite the absence of infection in humans (as evaluated by skin-snip microscopy). Ongoing transmission as demonstrated in the black flies could be due to a variety of factors, including lack of treatment of hypo-endemic areas and cross-border issues. Challenges identified during the course of the entomological work suggest that there is a need for improved selection of vector collection sites and vector collection periods in order to improve fly catches. Two important challenges to achieving elimination identified were definition of the hypo-endemic zones and establishing the existence of areas of cross-border transmission occurring between countries. PMID- 29471347 TI - Onchocerciasis: the beginning of the end. PMID- 29471348 TI - Sexual Dimorphism of Resting-State Network Connectivity in Healthy Ageing. AB - Objectives: The onset of many illnesses is confounded with age and sex. Increasing age is a risk factor for the development of many illnesses, and sexual dimorphism influences brain anatomy, function, and cognition. Here, we examine frequency-specific connectivity in resting-state networks in a large sample (n = 406) of healthy aged adults. Method: We quantify frequency-specific connectivity in three resting-state networks known to be implicated in age-related decline: the default mode, dorsal attention, and salience networks, using multiband functional magnetic resonance imaging. Frequency-specific connectivity was quantified in four bands: low (0.015-0.027 Hz), moderately low (0.027-0.073 Hz), moderately high (0.073-0.198 Hz), and high (0.198-0.5 Hz) frequency bands, using mean intensity and spatial extent. Differences in connectivity between the sexes in each of the three networks were examined. Results: Each network showed the largest intensity and spatial extent at low frequencies and smallest extent at high frequencies. Males showed greater connectivity than females in the salience network. Females showed greater connectivity than males in the default mode network. Discussion: Results in this healthy aged cohort are compatible with those obtained in young samples, suggesting that frequency-specific connectivity, and differences between the sexes, are maintained into older age. Our results indicate that sex should be considered as an influencing factor in studies of resting-state connectivity. PMID- 29471349 TI - Intestinal Colonization Traits of Pandemic Multidrug-Resistant Escherichia coli ST131. AB - Background: Epidemiological studies point to the gut as a key reservoir of multidrug resistant Escherichia coli multilocus sequence type 131 (ST131), a globally dominant pathogenic clone causing urinary tract and bloodstream infections. Here we report a detailed investigation of its intestinal lifestyle. Methods: Clinical ST131 isolates and type 1 fimbriae null mutants were assessed for colonization of human intestinal epithelia and in mouse intestinal colonization models. Mouse gut tissue underwent histologic analysis for pathology and ST131 localization. Key findings were corroborated in mucus-producing human cell lines and intestinal biopsy specimens. Results: ST131 strains adhered to and invaded human intestinal epithelial cells more than probiotic and commensal strains. The reference ST131 strain EC958 established persistent intestinal colonization in mice, and expression of type 1 fimbriae mediated higher colonization levels. Bacterial loads were highest in the distal parts of the mouse intestine and did not cause any obvious pathology. Further analysis revealed that EC958 could bind to both mucus and underlying human intestinal epithelia. Conclusions: ST131 strains can efficiently colonize the mammalian gut and persist long term. Type 1 fimbriae enhance ST131 intestinal colonization, suggesting that mannosides, currently developed as therapeutics for bladder infections and Crohn's disease, could also be used to limit intestinal ST131 reservoirs. PMID- 29471350 TI - Structural and mechanistic insights into UHRF1-mediated DNMT1 activation in the maintenance DNA methylation. AB - UHRF1 plays multiple roles in regulating DNMT1-mediated DNA methylation maintenance during DNA replication. The UHRF1 C-terminal RING finger functions as an ubiquitin E3 ligase to establish histone H3 ubiquitination at Lys18 and/or Lys23, which is subsequently recognized by DNMT1 to promote its localization onto replication foci. Here, we present the crystal structure of DNMT1 RFTS domain in complex with ubiquitin and highlight a unique ubiquitin binding mode for the RFTS domain. We provide evidence that UHRF1 N-terminal ubiquitin-like domain (UBL) also binds directly to DNMT1. Despite sharing a high degree of structural similarity, UHRF1 UBL and ubiquitin bind to DNMT1 in a very distinct fashion and exert different impacts on DNMT1 enzymatic activity. We further show that the UHRF1 UBL-mediated interaction between UHRF1 and DNMT1, and the binding of DNMT1 to ubiquitinated histone H3 that is catalyzed by UHRF1 RING domain are critical for the proper subnuclear localization of DNMT1 and maintenance of DNA methylation. Collectively, our study adds another layer of complexity to the regulatory mechanism of DNMT1 activation by UHRF1 and supports that individual domains of UHRF1 participate and act in concert to maintain DNA methylation patterns. PMID- 29471351 TI - Viability of Campylobacter spp. in frozen and chilled broiler carcasses according to real-time PCR with propidium monoazide pretreatment. AB - The aim of this study was to evaluate the viability of Campylobacter spp. in frozen and chilled broiler carcasses using real-time PCR with propidium monoazide (PMA) pretreatment. Sixty broiler carcasses were collected: 30 frozen and 30 chilled. Each carcass was submitted to 2 real-time PCR protocols to detect and quantify Campylobacter spp.: one using pretreatment with PMA, which blocks the amplification of DNA from dead bacteria, and the other without PMA. The results showed that PMA-pretreated carcasses, either frozen or chilled, had a lower positivity rate compared to untreated samples (P < 0.001). Regarding storage temperatures, PMA-pretreated frozen carcasses that tested positive were in a lesser number than chilled carcasses (P < 0.05). However, the quantification of total and live bacteria in PMA-pretreated frozen carcasses that tested positive showed no significant difference compared to chilled carcasses. It was concluded that the real-time PCR with PMA pretreatment was a sensitive method for evaluating the viability of Campylobacter spp. in broiler carcasses. Chilled broiler carcasses would represent greater hazard to public health concerning Campylobacter transmission. PMID- 29471352 TI - Delay to Formalin Fixation (Cold Ischemia Time) Effect on Breast Cancer Molecules. AB - Objectives: The gold standard of examining breast biomarkers, including estrogen receptor (ER)/progesterone receptor (PR)/human epidermal growth factor receptor 2 (HER2)/Ki-67, is to perform these assays on formalin-fixed, paraffin-embedded tissue. However, preanalytical variables may confound these assays. One of these factors is delay to formalin fixation (DFF). The purpose of this review is to evaluate each study that investigated the effect of DFF on breast biomarkers and other molecules. Methods: Thirteen primary research articles were identified by the literature search. The credibility of the studies was judged based on the degree of controlling other confounding factors. Nine studies had a prospective design with a high number of controlled variables. Results: Most of the studies concluded that DFF had an effect on ER/PR/HER2. Some of these studies showed that DFF had negative effect on other markers used either clinically or for research purposes. Conclusions: The vast majority of the studies agree that DFF has negative effect on breast biomarkers. PMID- 29471353 TI - Spleen Registry: Still a Chimera. PMID- 29471354 TI - A coliform-targeted metagenomic method facilitating human exposure estimates to Escherichia coli-borne antibiotic resistance genes. AB - Antimicrobial resistance and the spread of antibiotic resistance genes (ARGs) pose a threat to human health. Community-acquired infections resistant to treatment with first-line antibiotics are increasing, and there are few studies investigating environmental exposures and transmission. Our objective is to develop a novel targeted metagenomic method to quantify the abundance and diversity of ARGs in a faecal indicator bacterium, and to estimate human exposure to resistant bacteria in a natural environment. Sequence data from Escherichia coli metagenomes from 13 bathing waters in England were analysed using the ARGs Online Analysis Pipeline to estimate the abundance and diversity of resistance determinants borne by this indicator bacterium. These data were averaged over the 13 sites and used along with data on the levels of E. coli in English bathing waters in 2016 and estimates of the volume of water that water users typically ingest in an average session of their chosen activityto quantify the numbers of ARGs that water users ingest. Escherichia coli in coastal bathing waters were found to harbour on average 1.24 ARGs per cell. Approximately 2.5 million water sports sessions occurred in England in 2016 that resulted in water users ingesting at least 100 E. coli-borne ARGs. PMID- 29471355 TI - Closing the loop with an enhanced referral management system. AB - Objective: To evaluate the impact of a referral manager tool on primary care practices. Materials and Methods: We evaluated a referral manager module in a locally developed electronic health record (EHR) that was enhanced to improve the referral management process in primary care practices. Baseline (n = 61) and follow-up (n = 35) provider and staff surveys focused on the ease of performing various steps in the referral process, confidence in completing those steps, and user satisfaction. Additional metrics were calculated that focused on completed specialist visits, acknowledged notes, and patient communication. Results: Of 1341 referrals that were initiated during the course of the study, 76.8% were completed. All the steps of the referral process were easier to accomplish following implementation of the enhanced referral manager module in the EHR. Specifically, tracking the status of an in-network referral became much easier (+1.43 [3.91-2.48] on a 5-point scale, P < .0001). Although we found improvement in the ease of performing out-of-network referrals, there was a greater impact on in-network referrals. Discussion: Implementation of an electronic tool developed using user-centered design principles along with adequate staff to monitor and intervene when necessary made it easier for primary care practices to track referrals and to identify if a breakdown in the process occurred. This is especially important for high-priority referrals. Out-of-network referrals continue to present challenges, which may eventually be helped by improving interoperability among EHRs and scheduling systems. Conclusion: An enhanced referral manager system can improve referral workflows, leading to enhanced efficiency and patient safety and reduced malpractice risk. PMID- 29471356 TI - Characterization of p57, a Stage-Specific Antigen of Pneumocystis murina. AB - Pneumocystis has a large multicopy gene family encoding proteins related to the major surface glycoprotein (Msg), whose functions are largely unknown. We expressed one such protein of Pneumocystis murina, p57, which is encoded by 3 highly conserved genes, and demonstrated by immunoblot that immunocompetent mice that were immunized with crude Pneumocystis antigens or that had cleared Pneumocystis infection developed antibodies to p57. Using hyperimmune anti-p57 serum combined with immunolabeling, we found that p57 was expressed by small trophic forms and intracystic bodies, whereas it was not expressed on larger trophic forms or externally by cysts. Expression of p57 and Msg by trophic forms was largely mutually exclusive. Treatment of infected animals with caspofungin inhibited cyst formation and markedly decreased p57 expression. While p57 expression was seen in immunocompetent mice infected with Pneumocystis, immunization with recombinant p57 did not result in altered cytokine expression by lymphocytes or in diminished infection in such mice. Thus, p57 appears to be a stage-specific antigen of Pneumocystis that is expressed on intracystic bodies and young trophic forms and may represent a mechanism to conserve resources in organisms during periods of limited exposure to host immune responses. PMID- 29471357 TI - Obese Hypertensive Men Have Lower Circulating Proatrial Natriuretic Peptide Concentrations Despite Greater Left Atrial Size. AB - BACKGROUND: Obese persons have lower circulating natriuretic peptide (NP) concentrations. It has been proposed that this natriuretic handicap plays a role in obesity-related hypertension. In contrast, hypertensive patients with left atrial enlargement have higher circulating NP concentrations. On this background, we investigated whether obese hypertensive men could have lower circulating NP concentrations despite evidence of pressure-induced greater left atrial size. METHODS: We examined 98 obese men (body mass index [BMI] >= 30.0 kg/m2) and 27 lean normotensive men (BMI 20.0-24.9 kg/m2). All men were healthy, medication free, with normal left ventricular ejection fraction. We measured blood pressure using 24-hour ambulatory blood pressure (ABP) recordings. Hypertension was defined as 24-hour ABP >= 130/80 mm Hg, and normotension was defined as 24-hour ABP < 130/80 mm Hg. We determined left atrial size using echocardiography, and we measured fasting serum concentrations of midregional proatrial NP (MR-proANP). RESULTS: Of the 98 obese men, 62 had hypertension and 36 were normotensive. The obese hypertensive men had greater left atrial size (mean +/- SD: 28.7 +/- 6.0 ml/m2) compared with the lean normotensive men (23.5 +/- 4.5 ml/m2) and the obese normotensive men (22.7 +/- 5.1 ml/m2), P < 0.01. Nevertheless, despite evidence of pressure-induced greater left atrial size, the obese hypertensive men had lower serum MR-proANP concentrations (median [interquartile range]: 48.5 [37.0 64.7] pmol/l) compared with the lean normotensive men (69.3 [54.3-82.9] pmol/l), P < 0.01, whereas the obese normotensive men had serum MR-proANP concentrations in between the 2 other groups (54.1 [43.6-62.9] pmol/l). CONCLUSIONS: Despite greater left atrial size, obese hypertensive men have lower circulating MR-proANP concentrations compared with lean normotensive men. PMID- 29471358 TI - eIF4A alleviates the translational repression mediated by classical secondary structures more than by G-quadruplexes. AB - Increased activity of the mRNA helicase eIF4A drives cellular malignancy by reprogramming cellular translation, and eIF4A activity is the direct or indirect target of many emerging cancer therapeutics. The enriched presence of (GGC)4 motifs, which have the potential to fold into two-layered G-quadruplexes, within the 5'UTRs of eIF4A-dependent mRNAs suggests that eIF4A is required for the unwinding of these structures within these eIF4A-controlled mRNAs. However, the existence of folded G-quadruplexes within cells remains controversial, and G quadruplex folding is in direct competition with classical Watson-Crick based secondary structures. Using a combination of reverse transcription stalling assays and 7-deazaguanine incorporation experiments we find that (GGC)4 motifs preferentially form classical secondary structures rather than G-quadruplexes in full-length mRNAs. Furthermore, using translation assays with the eIF4A inhibitor hippuristanol, both in vitro and in cells, we find that eIF4A activity alleviates translational repression of mRNAs with 5'UTR classical secondary structures significantly more than those with folded G-quadruplexes. This was particularly evident in experiments using a G-quadruplex stabilizing ligand, where shifting the structural equilibrium in favour of G-quadruplex formation diminishes eIF4A dependency. This suggests that enrichment of (GGC)4 motifs in the 5'UTRs of eIF4A dependent mRNAs is due to the formation of stable hairpin structures rather than G-quadruplexes. PMID- 29471360 TI - Adverse Consequences of Unmet Needs for Care in High-Need/High-Cost Older Adults. AB - Objectives: We explore adverse consequences of unmet needs for care among high need/high-cost (HNHC) older adults. Method: Interviews with 4,024 community dwelling older adults with ADL/IADL/mobility disabilities from the 2011 National Health and Aging Trends Study (NHATS). Reports of socio-demographics, disability compensatory strategies, and adverse consequences of unmet needs in the past month were obtained from older adults with multiple chronic conditions (MCC), probable dementia (DEM), and/or near end-of-life (EOL) and compared older adults not meeting these criteria. Results: Older adults with MCC (31.6%), DEM (39.6%), and EOL (48.7%) reported significantly more adverse consequences than low-need older adults (21.4%). Persons with MCC & DEM (53.4%), MCC & EOL (53.2%), and all three (MCC, DEM, EOL, 65.6%) reported the highest levels of adverse consequences. HNHC participants reported more environmental modifications, assistive device, and larger helper networks. HNHC status independently predicted greater adverse consequences after controlling for disability compensatory strategies in multivariate models. Discussion: Adverse consequences of unmet needs for care are prevalent among HNHC older adults, especially those with multiple indicators, despite more disability-related compensatory efforts and larger helper networks. Helping caregivers provide better informal care has potential to contain healthcare costs by reducing hospitalization and unplanned readmissions. PMID- 29471361 TI - Microbial community composition along a 50 000-year lacustrine sediment sequence. AB - For decades, microbial community composition in subseafloor sediments has been the focus of extensive studies. In deep lacustrine sediments, however, the taxonomic composition of microbial communities remains undercharacterized. Greater knowledge on microbial diversity in lacustrine sediments would improve our understanding of how environmental factors, and resulting selective pressures, shape subsurface biospheres in marine and freshwater sediments. Using high-throughput sequencing of 16S rRNA genes across high-resolution climate intervals covering the last 50 000 years in Laguna Potrok Aike, Argentina, we identified changes in microbial populations in response to both past environmental conditions and geochemical changes of the sediment during burial. Microbial communities in Holocene sediments were most diverse, reflecting a layering of taxa linked to electron acceptors availability. In deeper intervals, the data show that salinity, organic matter and the depositional conditions over the Last Glacial-interglacial cycle were all selective pressures in the deep lacustrine assemblage resulting in a genetically distinct biosphere from the surface dominated primarily by Bathyarchaeota and Atribacteria groups. However, similar to marine sediments, some dominant taxa in the shallow subsurface persisted into the subsurface as minor fraction of the community. The subsequent establishment of a deep subsurface community likely results from a combination of paleoenvironmental factors that have shaped the pool of available substrates, together with substrate depletion and/or reworking of organic matter with depth. PMID- 29471362 TI - Changes in hospital bond ratings after the transition to a new electronic health record. AB - Objective: To assess the impact of electronic health record (EHR) implementation on hospital finances. Materials and Methods: We analyzed the impact of EHR implementation on bond ratings and net income from service to patients (NISP) at 32 hospitals that recently implemented a new EHR and a set of controls. Results: After implementing an EHR, 7 hospitals had a bond downgrade, 7 had a bond upgrade, and 18 had no changes. There was no difference in the likelihood of bond rating changes or in changes to NISP following EHR go-live when compared to control hospitals. Discussion: Most hospitals in our analysis saw no change in bond ratings following EHR go-live, with no significant differences observed between EHR implementation and control hospitals. There was also no apparent difference in NISP. Conclusions: Implementation of an EHR did not appear to have an impact on bond ratings at the hospitals in our analysis. PMID- 29471363 TI - Proteome Analysis of a M. avium Mutant Exposes a Novel Role of the Bifunctional Protein LysX in the Regulation of Metabolic Activity. AB - Lysyl-phosphatidylglycerol is one of the components of the mycobacterial membrane that contributes to the resistance to cationic antimicrobial peptides, a host induced frontline defense against invading pathogens. Its production is catalyzed by LysX, a bifunctional protein with lysyl transferase and lysyl transfer RNA synthetase activity. Comparative proteome analysis of a lysX mutant of Mycobacterium avium strain 104 and the wild type indicated that the lysX mutant strain undergoes a transition in phenotype by switching the carbon metabolism to beta-oxidation of fatty acids, along with accumulation of lipid inclusions. Surprisingly, proteins associated with intracellular survival were upregulated in the lysX mutant, even during extracellular growth, preparing bacteria for the conditions occurring inside host cells. In line with this, the lysX mutant exhibited enhanced intracellular growth in human-blood-derived monocytes. Thus, our study exposes the significance of lysX in the metabolism and virulence of the environmental pathogen M. avium hominissuis. PMID- 29471364 TI - Association of early- and adult-life socioeconomic circumstances with muscle strength in older age. AB - Background: socioeconomic circumstances (SEC) during a person's lifespan influence a wide range of health outcomes. However, solid evidence of the association of early- and adult-life SEC with health trajectories in ageing is still lacking. This study assessed whether early-life SEC are associated with muscle strength in later life-a biomarker of health-and whether this relationship is caused by adult-life SEC and health behaviours. Methods: we used data from the Survey of Health Ageing and Retirement in Europe, a 12-year population-based cohort study with repeated measurement in six waves (2004-15) and retrospective collection of life-course data. Participants' grip strength was assessed by using a handheld dynamometer. Confounder-adjusted logistic mixed-effect models were used to examine the associations of early- and adult-life SEC with the risk of low muscle strength (LMS) in older age. Results: a total of 24,179 participants (96,375 observations) aged 50-96 living in 14 European countries were included in the analyses. Risk of LMS was increased with disadvantaged relative to advantaged early-life SEC. The association between risk of LMS and disadvantaged early-life SEC gradually decreased when adjusting for adult-life SEC for both sexes and with unhealthy behaviours for women. After adjusting for these factors, all associations between risk of LMS and early-life SEC remained significant for women. Conclusion: early-life SEC are associated with muscle strength after adjusting for adult-life SEC and behavioural lifestyle factors, especially in women, which suggests that early life may represent a sensitive period for future health. PMID- 29471365 TI - Integrator subunit 4 is a 'Symplekin-like' scaffold that associates with INTS9/11 to form the Integrator cleavage module. AB - Integrator (INT) is a transcriptional regulatory complex associated with RNA polymerase II that is required for the 3'-end processing of both UsnRNAs and enhancer RNAs. Integrator subunits 9 (INTS9) and INTS11 constitute the catalytic core of INT and are paralogues of the cleavage and polyadenylation specificity factors CPSF100 and CPSF73. While CPSF73/100 are known to associate with a third protein called Symplekin, there is no paralog of Symplekin within INT raising the question of how INTS9/11 associate with the other INT subunits. Here, we have identified that INTS4 is a specific and conserved interaction partner of INTS9/11 that does not interact with either subunit individually. Although INTS4 has no significant homology with Symplekin, it possesses N-terminal HEAT repeats similar to Symplekin but also contains a beta-sheet rich C-terminal region, both of which are important to bind INTS9/11. We assess three functions of INT including UsnRNA 3'-end processing, maintenance of Cajal body structural integrity, and formation of histone locus bodies to conclude that INTS4/9/11 are the most critical of the INT subunits for UsnRNA biogenesis. Altogether, these results indicate that INTS4/9/11 compose a heterotrimeric complex that likely represents the Integrator 'cleavage module' responsible for its endonucleolytic activity.

AB - Objective: Although evidence suggests that neighborhood conditions are related to stress and health, the processes connecting neighborhood conditions and stress for older minorities is little explored. The purpose of this analysis is to contribute new insights into this issue. Method: We conducted a qualitative analysis as part of a larger mixed methods study of 100 African Americans aged 55 years and older living in neighborhoods of varying quality in Detroit, Michigan. A subsample of (n = 20) older adults took photographs of bothersome aspects of their neighborhoods and participated in in-depth photo-elicitation interviews. Data were analyzed using a grounded theory approach. Results: "Loss of trust in the neighborhood" emerged as the core category to explain how older African Americans in our sample experienced neighborhood stressors in their daily lives. Loss of trust in physical, social, and institutional dimensions of the neighborhood contributed to the core category. Discussion : The life course of neighborhoods and the trust placed in them appears to be intimately connected to the well-being of older African Americans. We therefore hypothesize that a fundamental pathway through which neighborhood stressors are experienced for older African Americans in United States "Rust Belt" cities is the multifaceted loss of trust in the neighborhood.

AB - Background: Doffing protocols for personal protective equipment (PPE) are critical for keeping healthcare workers (HCWs) safe during care of patients with Ebola virus disease. We assessed the relationship between errors and self contamination during doffing. Methods: Eleven HCWs experienced with doffing Ebola level PPE participated in simulations in which HCWs donned PPE marked with surrogate viruses (phi6 and MS2), completed a clinical task, and were assessed for contamination after doffing. Simulations were video recorded, and a failure modes and effects analysis and fault tree analyses were performed to identify errors during doffing, quantify their risk (risk index), and predict contamination data. Results: Fifty-one types of errors were identified, many having the potential to spread contamination. Hand hygiene and removing the powered air purifying respirator (PAPR) hood had the highest total risk indexes (111 and 70, respectively) and number of types of errors (9 and 13, respectively). phi6 was detected on 10% of scrubs and the fault tree predicted a 10.4% contamination rate, likely occurring when the PAPR hood inadvertently contacted scrubs during removal. MS2 was detected on 10% of hands, 20% of scrubs, and 70% of inner gloves and the predicted rates were 7.3%, 19.4%, 73.4%, respectively. Fault trees for MS2 and phi6 contamination suggested similar pathways. Conclusions: Ebola-level PPE can both protect and put HCWs at risk for self-contamination throughout the doffing process, even among experienced HCWs doffing with a trained observer. Human factors methodologies can identify error prone steps, delineate the relationship between errors and self-contamination, and suggest remediation strategies. PMID- 29471367 TI - Evolution of genes associated with gynoecium patterning and fruit development in Solanaceae. AB - Background and Aims: The genetic basis of fruit development has been extensively studied in Arabidopsis, where major transcription factors controlling valve identity (i.e. FRUITFULL), replum development (i.e. REPLUMLESS) and the differentiation of the dehiscence zones (i.e. SHATTERPROOF, INDEHISCENT and ALCATRAZ) have been identified. This gene regulatory network in other flowering plants is influenced by duplication events during angiosperm diversification. Here we aim to characterize candidate fruit development genes in the Solanaceae and compare them with those of Brassicaceae. Methods: ALC/SPT, HEC/IND, RPL and AG/SHP homologues were isolated from publicly available databases and from our own transcriptomes of Brunfelsia australis and Streptosolen jamesonii. Maximum likelihood phylogenetic analyses were performed for each of the gene lineages. Shifts in protein motifs, as well as expression patterns of all identified homologues, are shown in dissected floral organs and fruits in different developmental stages of four Solanaceae species exhibiting different fruit types. Key Results: Each gene lineage has undergone different duplication time-points, resulting in very different genetic complements in the Solanaceae when compared with the Brassicaceae. In general, Solanaceae species have more copies of HEC1/2 and RPL than Brassicaceae, have fewer copies of SHP and the same number of copies of AG, ALC and SPT. Solanaceae lack IND orthologues, but have pre-duplication HEC3 homologues. The expression analyses showed opposite expression of SPT and ALC orthologues between dry- and fleshy-fruited species during fruit maturation. Fleshy-fruited species turn off RPL and SPT orthologues during maturation. Conclusions: The gynoecium patterning and fruit developmental genetic network in the Brassicaceae cannot be directly extrapolated to the Solanaceae. In Solanaceae ALC, SPT and RPL contribute differently to maturation of dry dehiscent and fleshy fruits, whereas HEC genes are not generally expressed in the gynoecium. RPL genes have broader expression patterns than expected. PMID- 29471369 TI - Genome-wide association study of Stayability and Heifer Pregnancy in Red Angus cattle. AB - Reproductive performance is the most important component of cattle production from the standpoint of economic sustainability of commercial beef enterprises. Heifer Pregnancy (HPG) and Stayability (STAY) genetic predictions are 2 selection tools published by the Red Angus Association of America (RAAA) to assist with improvements in reproductive performance. Given the importance of HPG and STAY to the profitability of commercial beef enterprises, the objective of this study was to identify QTL associated with both HPG and STAY in Red Angus cattle. A genome wide association study (GWAS) was performed using deregressed HPG and STAY EBV, calculated using a single-trait animal model and a 3-generation pedigree with data from the Spring 2015 RAAA National Cattle Evaluation. Each individual animal possessed 74,659 SNP genotypes. Individual animals with a deregressed EBV reliability > 0.05 were merged with the genotype file and marker quality control was performed. Criteria for sifting genotypes consisted of removing those markers where any of the following were found: average call rate less than 0.85, minor allele frequency < 0.01, lack of Hardy-Weinberg equilibrium (P < 0.0001), or extreme linkage disequilibrium (r2 > 0.99). These criteria resulted in 2,664 animals with 62,807 SNP available for GWAS. Association studies were performed using a Bayes Cpi model in the BOLT software package. Marker significance was calculated as the posterior probability of inclusion (PPI), or the number of instances a specific marker was sampled divided by the total number of samples retained from the Markov chain Monte Carlo chains. Nine markers, with a PPI >= 3% were identified as QTL associated with HPG on BTA 1, 11, 13, 23, and 29. Twelve markers, with a PPI >= 75% were identified as QTL associated with STAY on BTA 6, 8, 9, 12, 15, 18, 22, and 23. PMID- 29471370 TI - Competitive ability of Capsella species with different mating systems and ploidy levels. AB - Background and Aims: Capsella is a model genus for studying the transition from outcrossing to selfing, with or without change in ploidy levels. The genomic consequences and changes in reproductive traits (selfing syndrome) associated with these shifts have been studied in depth. However, potential ecological divergence among species of the genus has not been determined. Among ecological traits, competitive ability could be relevant for selfing evolution, as selfing has been shown to be statistically associated with reduced competitiveness in a recent meta-analysis. Methods: We assessed the effect of competition on three Capsella species differing in their mating system and ploidy level. We used an experimental design where fitness related traits were measured in focal individuals with and without competitors. Key Results: The diploid selfer (C. rubella) was most sensitive to competition, whereas the tetraploid selfer (C. bursa-pastoris) performed the best, with the diploid outcrosser (C. grandiflora) being intermediate. Conclusions: These results add to the detailed characterization of Capsella species and highlight the possible roles of ecological context and ploidy in the evolutionary trajectories of selfing species. PMID- 29471371 TI - Digital holography and its multidimensional imaging applications: a review. AB - In this review, we introduce digital holographic techniques and recent progress in multidimensional sensing by using digital holography. Digital holography is an interferometric imaging technique that does not require an imaging lens and can be used to perform simultaneous imaging of multidimensional information, such as three-dimensional structure, dynamics, quantitative phase, multiple wavelengths and polarization state of light. The technique can also obtain a holographic image of nonlinear light and a three-dimensional image of incoherent light with a single-shot exposure. The holographic recording ability of this technique has enabled a variety of applications. PMID- 29471372 TI - A Multistate Outbreak of Human Salmonella Agona Infections Associated With Consumption of Fresh, Whole Papayas Imported From Mexico-United States, 2011. AB - Background: Nontyphoidal Salmonella causes ~1 million food-borne infections annually in the United States. We began investigating a multistate outbreak of Salmonella serotype Agona infections in April 2011. Methods: A case was defined as infection with the outbreak strain of Salmonella Agona occurring between 1 January and 25 August 2011. We developed hypotheses through iterative interviews. Product distribution analyses and traceback investigations were conducted. The Food and Drug Administration (FDA) tested papayas from Mexico for Salmonella. Results: We identified 106 case patients from 25 states. Their median age was 21 years (range, 1-91). Thirty-nine of 61 case patients (64%) reported Hispanic/Latino ethnicity; 11 of 65 (17%) travelled to Mexico before illness. Thirty-two of 56 case patients (57%) reported papaya consumption. Distribution analyses revealed that three firms, including Distributor A, distributed papaya to geographic areas that aligned with both the location and timing of illnesses. Traceback of papayas purchased by ill persons in four states identified Distributor A as the common supplier. FDA testing isolated the outbreak strain from a papaya sample collected at distributor A and from another sample collected at the US-Mexico border, destined for distributor A. FDA isolated Salmonella species from 62 of 388 papaya import samples (16%). The investigation led to a recall of fresh, whole papayas from Distributor A and an FDA import alert for all papayas from Mexico. Conclusions: This is the first reported Salmonella outbreak in the United States linked to fresh, whole papayas. The outbreak highlights important issues regarding the safety of imported produce. PMID- 29471373 TI - Deep Brain Stimulation of the Subthalamic Nucleus Parameter Optimization for Vowel Acoustics and Speech Intelligibility in Parkinson's Disease. AB - Purpose: The settings of 3 electrical stimulation parameters were adjusted in 12 speakers with Parkinson's disease (PD) with deep brain stimulation of the subthalamic nucleus (STN-DBS) to examine their effects on vowel acoustics and speech intelligibility. Method: Participants were tested under permutations of low, mid, and high STN-DBS frequency, voltage, and pulse width settings. At each session, participants recited a sentence. Acoustic characteristics of vowel production were extracted, and naive listeners provided estimates of speech intelligibility. Results: Overall, lower-frequency STN-DBS stimulation (60 Hz) was found to lead to improvements in intelligibility and acoustic vowel expansion. An interaction between speaker sex and STN-DBS stimulation was found for vowel measures. The combination of low frequency, mid to high voltage, and low to mid pulse width led to optimal speech outcomes; however, these settings did not demonstrate significant speech outcome differences compared with the standard clinical STN-DBS settings, likely due to substantial individual variability. Conclusions: Although lower-frequency STN-DBS stimulation was found to yield consistent improvements in speech outcomes, it was not found to necessarily lead to the best speech outcomes for all participants. Nevertheless, frequency may serve as a starting point to explore settings that will optimize an individual's speech outcomes following STN-DBS surgery.

AB - Objective: To investigate the effect of TNF inhibitors (TNFis) on incidental and progressive hand OA in recent-onset RA patients after a 10 year follow-up. Methods: Radiographs of 262 RA patients (mean age 52 years, 66% women) from the BeSt study were scored for osteophytes in DIP/PIP joints using the Osteoarthritis Research Society International atlas (0-3; summed score 0-54) and according to the Kellgren-Lawrence (KL) score (0-4; summed score 0-72) at baseline and 10 year follow-up. TNFi treatment was assessed on visits every 3 months. Associations between TNFi treatment and hand OA were analysed on the patient and joint level using generalized linear models and generalized estimating equations, respectively. Results: Fifty-eight percent of the patients were treated with TNFi, with a median duration of 42 months. A total of 143 patients (55%) had hand OA in any IP joint at baseline based on the Osteoarthritis Research Society International osteophyte score. On the patient level, TNFi treatment duration did not affect incidental hand OA. However, every month of TNFi treatment resulted in a reduced relative risk (RR) of hand OA progression in DIP joints [relative risk (RR) 0.987 (95% CI 0.978, 0.996)] but not in PIP joints. On the joint level, the effect on hand OA progression was observed in DIP joints [RR 0.996 (95% CI 0.991, 1.000)] but not in PIP joints. The results from the KL score analyses were comparable to the osteophyte score. Conclusion: TNFi treatment was associated with a reduced risk on radiographic hand OA progression in DIP joints but not in PIP joints after 10 years. Although the effect sizes are small, these results provide evidence for influence of TNF-alpha in hand OA pathogenesis. PMID- 29471378 TI - Communicative Function Use of Preschoolers and Mothers From Differing Racial and Socioeconomic Groups. AB - Purpose: This study explores whether communicative function (CF: reasons for communicating) use differs by socioeconomic status (SES), race/ethnicity, or gender among preschoolers and their mothers. Method: Mother-preschooler dyads (N = 95) from the National Center for Early Development and Learning's (2005) study of family and social environments were observed during 1 structured learning and free-play interaction. CFs were coded by trained independent raters. Results: Children used all CFs at similar rates, but those from low SES homes produced fewer utterances and less reasoning, whereas boys used less self-maintaining and more predicting. African American mothers produced more directing and less responding than European American and Latino American mothers, and Latino American mothers produced more utterances than European American mothers. Mothers from low SES homes did more directing and less responding. Conclusions: Mothers exhibited more sociocultural differences in CFs than children; this suggests that maternal demographic characteristics may influence CF production more than child demographics at school entry. Children from low SES homes talking less and boys producing less self-maintaining coincided with patterns previously detected in pragmatic literature. Overall, preschoolers from racial/ethnic minority and low SES homes were not less deft with CF usage, which may inform how their pragmatic skills are described.

Results from a Cohort of Cancer Patients. AB - Complex exposure situations are frequent at the workplace, but few studies have characterized multiple occupational carcinogenic exposures (MOCE) and their gendered differences across jobs' characteristics. We assessed MOCE separately in male and female jobs and identified patterns of MOCE at job level. Participants (834 men and 183 women) were cancer patients recruited between March 2002 and December 2010 in the ongoing SCOP93 cohort study, Seine-Saint-Denis department, France. Job histories were collected through personal interviews, and carcinogenic exposures were assessed by a multidisciplinary expert committee using a list of 53 carcinogens. Proportion of MOCE (i.e. >=2 carcinogens) was assessed for male and female jobs separately. Principal component analysis combined with hierarchical ascendant classification was used to identify patterns of MOCE. Among the 5202 male jobs and 885 female jobs, respectively 42 and 9% were multi-exposed. Blue-collar workers and jobs in the construction and industry sectors had the highest rates of MOCE, contrasting with jobs held in recent periods (>=1997) and by patients aged >=45 years at job start. A gradient of MOCE was also observed according to occupational segregation for both men and women. Eight patterns of MOCE were identified among male jobs: widespread carcinogens, mixed silica dust, heavy metals/combustion products, organic compounds/radiation, metal working, solvents/heavy metals, wood dust/formaldehyde/pesticides, and fuel exhausts. Three patterns of MOCE were found among female jobs: biological/organic compounds, industrial working, and fuel exhausts. Some patterns of MOCE were job specific, whereas other patterns were found across different occupations. These results suggest that patterns of MOCE partly differ between men and women. They stress the importance of gendering multiple exposure assessment studies and point out the inadequacy of occupational disease compensation systems based on a single factor and non-gendered approach of carcinogenesis, ignoring differences between men and women in complex occupational exposure situations. PMID- 29471380 TI - Dysarthria in Mandarin-Speaking Children With Cerebral Palsy: Speech Subsystem Profiles. AB - Purpose: This study explored the speech characteristics of Mandarin-speaking children with cerebral palsy (CP) and typically developing (TD) children to determine (a) how children in the 2 groups may differ in their speech patterns and (b) the variables correlated with speech intelligibility for words and sentences. Method: Data from 6 children with CP and a clinical diagnosis of moderate dysarthria were compared with data from 9 TD children using a multiple speech subsystems approach. Acoustic and perceptual variables reflecting 3 speech subsystems (articulatory-phonetic, phonatory, and prosodic), and speech intelligibility, were measured based on speech samples obtained from the Test of Children's Speech Intelligibility in Mandarin (developed in the lab for the purpose of this research). Results: The CP and TD children differed in several aspects of speech subsystem function. Speech intelligibility scores in children with CP were influenced by all 3 speech subsystems, but articulatory-phonetic variables had the highest correlation with word intelligibility. All 3 subsystems influenced sentence intelligibility. Conclusion: Children with CP demonstrated deficits in speech intelligibility and articulation compared with TD children. Better speech sound articulation influenced higher word intelligibility, but did not benefit sentence intelligibility. PMID- 29471382 TI - Gendered Safety and Health Risks in the Construction Trades. AB - Objectives: Despite women's increased representation in the overall workforce, construction remains a male-dominated industry. Prior studies have noted that the hazardous workplace environment combined with a culture that can be discriminatory and openly hostile can threaten women workers' health and safety. However, little information exists about the current physical and psychosocial hazards at work affecting tradeswomen. Methods: We examined differences in workplace exposure between women and men, and the association of these exposures with self-reported stress and work injury, in order to highlight how gendered conditions of work negatively affect tradeswomen's health. A holistic view of health that included the influence of both home and work spheres as well as hazards related to women's social experience was considered. Almost 300 workers (198 tradeswomen and 93 tradesmen) throughout Washington State completed surveys. We used descriptive statistics to compare exposures between genders, and logistic regression to model the association between psychosocial exposures and injury and stress outcomes. Results: We found that women were significantly more likely than men to report high perceived stress (31 and 18%, respectively) and being injured at work in the past year (31 and 12%, respectively). Ten of the 12 work-related psychosocial exposures were found to be associated with either stress (job strain, gender and age discrimination, bullying, work/life balance, isolation, sexual harassment, safety climate, and social support) or injury (gender discrimination, bullying, overcompensation, and sexual harassment) for women. Conclusions: The industry continues to lag in supporting tradeswomen's health and safety needs. This study suggests that multiple exposures (including discrimination, overcompensation, and work/life balance) have an important impact on worker well-being. The findings underscore the complex interaction of gender, psychosocial exposures, and occupational risks, and indicate areas for intervention. PMID- 29471381 TI - Efficacy of Vedolizumab in Fistulising Crohn's Disease: Exploratory Analyses of Data from GEMINI 2. AB - Background and Aims: Medical management of fistulising Crohn's disease [CD] is constrained by the limited number of available therapies. We evaluated the efficacy of vedolizumab, a gut-selective alpha4beta7 integrin antagonist approved for treating moderately to severely active CD, in a subpopulation of patients with fistulising CD who participated in the GEMINI 2 trial [NCT00783692]. Methods: Exploratory analyses of data from the GEMINI 2 trial were conducted in 461 responders to 6-week vedolizumab induction therapy who received maintenance placebo [VDZ/PBO, N = 153] or vedolizumab [VDZ/VDZ, N = 308]. Fistula closure rates were assessed at Weeks 14 and 52, and the time to fistula closure was analysed by the Cox proportional hazards model with adjustments for significant covariates. Results: At entry into the maintenance period, 153 [33%] patients had a history of fistulising disease and 57 [12%] patients had >=1 active draining fistula. By Week 14, 28% of VDZ/VDZ-treated patients compared with 11% of VDZ/PBO treated patients (95% confidence interval [CI], -11.4 to 43.9) achieved fistula closure. Corresponding rates at Week 52 were 31% and 11% (absolute risk reduction [ARR]: 19.7%; 95% CI, -8.9 to 46.2). Similarly, VDZ/VDZ-treated patients had faster time to fistula closure and were more likely to have fistula closure at Week 52 [33% vs 11%; HR: 2.54; 95% CI, 0.54-11.96]. Prior failure of antibiotic therapy was a negative predictor of fistula closure [HR: 0.217; 95% CI, 0.059 0.795; p = 0.021], whereas trough vedolizumab concentrations did not affect closure rates. Conclusions: Our findings are consistent with the beneficial effect of vedolizumab treatment for fistulising CD. PMID- 29471384 TI - Increased BMI in children-an indicator for less compliance during orthodontic treatment with removable appliances. AB - Aim: To assess whether or not childhood overweight is associated with lower levels of compliance during orthodontic therapy with removable appliances. Materials and methods: Starting in 2011, all upper expansion plates and Sander II appliances were equipped with a Theramon(r) microsensor chip to assess appliance wear time objectively. According to their pre-treatment, BMI normal weight patients were matched to consecutively treated overweight or obese patients by gender, age, and appliance type. Cooperation was assessed with microelectronic wear time documentation over a period of at least 6 months. Results: A total of 50 patients (25 overweight, 25 normal weight) with upper expansion plates and 64 patients (32 overweight, 32 normal weight) with Sander II appliances were analysed. Spearman Rho coefficients showed an indirect association between BMI and appliance wear time, indicating that the higher the BMI, the less the patients wore their appliances (P < 0.05). Furthermore, both normal- and overweight children wore upper expansion plates significantly more than Sander II appliances (P < 0.05). Although no gender-specific difference was found (P = 0.723), an age-related correlation could be verified, indicating a decrease in wear time with increasing age (P < 0.05). Conclusions: An increased BMI appears to be a risk factor for less appliance wear during orthodontic treatment with removable appliances. Additional factors which influenced cooperation during treatment with removable appliances were patient age and appliance type. PMID- 29471383 TI - Genetic analysis of calf health in Charolais beef cattle. AB - The objective of this study was to investigate the factors that influence calf health and survival in Charolais cattle. Data from 2,740 calves, originating from 16 French farms and observed from birth until 30 d of age, were analyzed using models that took account of direct genetic, maternal genetic, and common environmental effects. Both direct and maternal genetic parameters were estimated for birth weight (BW), calving ease (CE), neonatal vitality (NV), survival at 30 d (Surv), and umbilical infection and diarrhea at different ages (0 to 5 d: Umb1 and Diar1; 6 to 20 d: Umb2 and Diar2; and 21 to 30 d: Umb3 and Diar3). The heritability values for direct and maternal genetic effects were, 0.026 (SE = 0.027) and 0.096 (SE = 0.042) for Surv, 0.280 (SE = 0.063) and 0.063 (SE = 0.038) for BW, 0.129 (SE = 0.041) and 0 for CE, 0.073 (SE = 0.035) and 0 for NV, 0.071 (SE = 0.038) and 0.017 (SE = 0.026) for Umb1, 0 and 0.082 (SE = 0.029) for Umb2, 0 and 0.044 (SE = 0.030) for Diar1, 0.016 (SE = 0.022) and 0.012 (SE = 0.026) for Diar2, and 0.016 (SE = 0.028) and 0 for Diar3, respectively. Significant genetic variability in beef cattle was thus revealed for five calf health traits: NV, Surv, Diar1, Umb1, and Umb2. In addition, for three traits (Surv, Diar1, and Umb2), maternal genetic effects clearly contributed more to health performance than direct genetic effects. Estimates of genetic correlation between traits varied markedly (from 0 to 1 in absolute values) depending on the traits in question, the age for a given trait, and the type (direct or maternal) of the genetic effects considered. These results suggest that not all health traits in Charolais cattle can be improved simultaneously, and breeders will therefore have to prioritize certain traits of interest in their breeding objectives. Overall, our results demonstrate the potential utility of collecting and integrating data on calf diseases, NV and survival in future beef cattle breeding programs. To ensure appropriate biological and genetic evaluations of calf health performance, it is important to accurately describe the phenotypes for diarrhea and umbilical infections (in terms of age ranges) and account for maternal genetic and common environmental effects that explain calf health performance traits. Further investigation and improved data collection are now necessary to maximize the efficiency of breeding schemes designed to simultaneously improve production and health traits. PMID- 29471385 TI - Functional neural correlates of slower gait among older adults with mild cognitive impairment. AB - Background: Subtle, but observable, changes in mobility often exist among older adults with mild cognitive impairment (MCI). Notably, these changes are not inconsequential. Therefore, there is a strong interest to better understand the underlying neural correlates of gait slowing among older adults with MCI. In this study, we aimed to characterize patterns of functional connectivity associated with slower gait speed in older adults with MCI. Methods: 49 participants >= 60 years with MCI were included in the cross-sectional study. All participants underwent assessments of gait speed and resting state functional magnetic resonance imaging. Results: In this sample of older adults with MCI, slower usual gait was characterized by altered connectivity between the sensorimotor network (SMN) and the frontoparietal network (FPN) (p<0.05) - specifically, slower usual gait was associated with greater connectivity between the supplementary motor area (SMA) and the bilateral ventral visual (BVV) cortices (p=0.01); lower connectivity between the SMA and the bilateral superior lateral occipital cortex (BSLOC) (p<0.01); and lower connectivity between the SMA and the bilateral frontal eye field (BFEF) (p<0.01). Conclusion: Altered inter-network functional connectivity between the SMN and FPN may be a neural mechanism for slowing of gait in older adults with MCI.

AB - This study investigated age-related changes in behavioral and neural complexity for a polyrhythmic movement, which appeared to be an exception to the loss of complexity hypothesis. Young (n = 15; age = 24.2 years) and older (15; 68.1 years) adults performed low-level force-tracking with isometric index abduction to couple a compound sinusoidal target. Multiscale entropy (MSE) of tracking force and inter-spike interval (ISI) of motor unit (MU) in the first dorsal interosseus muscle were assessed. The MSE area of tracking force at shorter time scales of older adults was greater (more complex) than that of young adults, whereas an opposite trend (less complex for the elders) was noted at longer time scales. The MSE area of force fluctuations (the stochastic component of the tracking force) were generally smaller (less complex) for older adults. Along with greater mean and coefficient of ISI, the MSE area of the cumulative discharge rate of elders tended to be lower (less complex) than that of young adults. In conclusion, age-related complexity changes in polyrhythmic force tracking depended on the time scale. The adaptive behavioral consequences could be multifactorial origins of the age-related impairment in rate coding, increased discharge noises, and lower discharge complexity of pooled MUs. PMID- 29471387 TI - Heavy Cannabis Use Associated With Reduction in Activated and Inflammatory Immune Cell Frequencies in Antiretroviral Therapy-Treated Human Immunodeficiency Virus Infected Individuals. AB - Background: Cannabis is a widely used drug in the United States, and the frequency of cannabis use in the human immunodeficiency virus (HIV)-infected population is disproportionately high. Previous human and macaque studies suggest that cannabis may have an impact on plasma viral load; however, the relationship between cannabis use and HIV-associated systemic inflammation and immune activation has not been well defined. Methods: The impact of cannabis use on peripheral immune cell frequency, activation, and function was assessed in 198 HIV-infected, antiretroviral-treated individuals by flow cytometry. Individuals were categorized into heavy, medium, or occasional cannabis users or noncannabis users based on the amount of the cannabis metabolite 11-nor-carboxy tetrahydrocannabinol (THC-COOH) detected in plasma by mass spectrometry. Results: Heavy cannabis users had decreased frequencies of human leukocyte antigen (HLA) DR+CD38+CD4+ and CD8+ T-cell frequencies, compared to frequencies of these cells in non-cannabis-using individuals. Heavy cannabis users had decreased frequencies of intermediate and nonclassical monocyte subsets, as well as decreased frequencies of interleukin 23- and tumor necrosis factor-alpha-producing antigen presenting cells. Conclusions: While the clinical implications are unclear, our findings suggest that cannabis use is associated with a potentially beneficial reduction in systemic inflammation and immune activation in the context of antiretroviral-treated HIV infection. PMID- 29471389 TI - The effect of paternal factors on perinatal and paediatric outcomes: a systematic review and meta-analysis. AB - BACKGROUND: Maternal factors, including increasing childbearing age and various life-style factors, are associated with poorer short- and long-term outcomes for children, whereas knowledge of paternal parameters is limited. Recently, increasing paternal age has been associated with adverse obstetric outcomes, birth defects, autism spectrum disorders and schizophrenia in children. OBJECTIVE AND RATIONALE: The aim of this systematic review is to describe the influence of paternal factors on adverse short- and long-term child outcomes. SEARCH METHODS: PubMed, Embase and Cochrane databases up to January 2017 were searched. Paternal factors examined included paternal age and life-style factors such as body mass index (BMI), adiposity and cigarette smoking. The outcome variables assessed were short-term outcomes such as preterm birth, low birth weight, small for gestational age (SGA), stillbirth, birth defects and chromosomal anomalies. Long term outcome variables included mortality, cancers, psychiatric diseases/disorders and metabolic diseases. The systematic review follows PRISMA guidelines. Relevant meta-analyses were performed. OUTCOMES: The search included 14 371 articles out of which 238 met the inclusion criteria, and 81 were included in quantitative synthesis (meta-analyses). Paternal age and paternal life-style factors have an association with adverse outcome in offspring. This is particularly evident for psychiatric disorders such as autism, autism spectrum disorders and schizophrenia, but an association is also found with stillbirth, any birth defects, orofacial clefts and trisomy 21. Paternal height, but not BMI, is associated with birth weight in offspring while paternal BMI is associated with BMI, weight and/or body fat in childhood. Paternal smoking is found to be associated with an increase in SGA, birth defects such as congenital heart defects, and orofacial clefts, cancers, brain tumours and acute lymphoblastic leukaemia. These associations are significant although moderate in size, with most pooled estimates between 1.05 and 1.5, and none exceeding 2.0. WIDER IMPLICATIONS: Although the increased risks of adverse outcome in offspring associated with paternal factors and identified in this report represent serious health effects, the magnitude of these effects seems modest.

PMID- 29471392 TI - Effects of fermentation on the hemolytic activity and degradation of Camellia oleifera saponins by Lactobacillus crustorum and Bacillus subtilis. AB - The saponins, as components of tea seed meal, are undesirable hemolytic components and should be degraded for reducing their hemolytic activity in order to be used in animal feed. In this study, beta-glucuronidase was verified to be a potent hydrolase of tea seed saponins to reduce their hemolytic activity and a beta-glucuronidase-producing Lactobacillus crustorum strain was screened from raw bovine milk. Next, solid-state fermentation with the isolated L. crustorum and a Bacillus subtilis natto strain, which can produce cellulase and hence improve the fermentation performance of tea seed meal, was carried out for detoxification of tea seed meal. The 50% hemolytic dosage (HD50) value of tea seed saponins was increased from 6.69 to 27.43 MUg mL-1. The results of LC-MS analysis showed that the percentage of saponin aglycones increased from 30.95 to 84.25% after the fermentation. According to the roles of sugar moieties in hemolytic activity, and the enzymatic hydrolysis characteristics of beta-glucuronidase, the degradation of tea seed saponins from glucosides to aglycones may contribute to the reduction of hemolytic activity. Therefore, tea seed meal may be used as animal feed after fermentation with the tested saponin-degrading microbial strains. PMID- 29471391 TI - Comparative efficacy of enrofloxacin to that of tulathromycin for the control of bovine respiratory disease and prevalence of antimicrobial resistance in Mannheimia haemolytica in calves at high risk of developing bovine respiratory disease. AB - Bovine respiratory disease (BRD) is the most common cause of morbidity and mortality in North American beef cattle. Mannheimia haemolytica is the bacterial pathogen most often isolated from cattle with BRD, and the prevalence of antimicrobial resistance (AMR) in this organism has increased in recent years. Antimicrobials are commonly used to prevent BRD in cattle at high risk of developing BRD; however, recent work would suggest that this practice might be one factor contributing to the increased prevalence of AMR in M. haemolytica. We hypothesized that the administration of the short-acting fluoroquinolone, enrofloxacin, would be just as effective as the long-acting triamilide, tulathromycin, in preventing BRD but would be less likely to select for AMR M. haemolytica in stocker calves at high risk of developing BRD. Three hundred forty one stocker calves were enrolled in the study with 172 calves in 4 pens being randomly assigned to treatment with enrofloxacin and 169 calves in 4 pens randomly assigned to treatment with tulathromycin. Calves within each treatment group were allocated to one of 4 replicate pens based on the week of enrollment. Of calves receiving enrofloxacin, 33.7% required treatment for BRD at least once within 45 d after arrival, compared with 18.3% of calves receiving tulathromycin (P = 0.040). The percentages of calves that required more than one treatment for BRD within 45 d after arrival did not differ statistically for those receiving enrofloxacin compared with those receiving tulathromycin (10.5% and 4.7%, respectively; P = 0.107) Likewise, the percentages of calves that died during the 45-d follow-up period did not differ for those receiving enrofloxacin compared with those receiving tulathromycin (12.2% and 10.1%, respectively; P = 0.592). Mannheimia haemolytica was cultured from 11% of calves sampled at arrival and from 50% of calves sampled at revaccination 14 to 17 d later. There was a significanst effect of sampling time on the proportion of calves carrying multidrug-resistant (MDR) isolates, with calves having a higher prevalence of MDR isolates at revaccination than arrival (100% vs. 13%; P < 0.001). Future research evaluating the impact of MDR on response to antimicrobial therapy is necessary. PMID- 29471393 TI - The Severe Impairment Profile: A Conceptual Shift. AB - Objective: The current study sought to evaluate and replicate the severe impairment profile (SIP) of the Word Memory Test (WMT) in patients referred for dementia evaluations. Method: The sample consisted of 125 patients referred for a neuropsychological evaluation at a large Veterans Affairs Medical Center. Patients were assigned a Clinical Dementia Rating (CDR) by blind raters, and were classified according to their performance on performance validity testing. Subsequent chart reviews were conducted to help in more accurately determining the presence of severe memory impairment likely due to an underlying dementing process versus poor effort/task engagement. Results: In our sample, 51% of patients failed easy WMT subtests and 93% of these patients obtained the SIP. The rates of failure on these easy subtests generally coincided with both more severely impaired CDR ratings, as well as more impaired delayed memory composite scores. Upon chart review, it was determined that there were likely a significant portion of classification errors using the SIP, with a positive posttest probability of impairment based on having the SIP being 65% as opposed to 28% for a negative result. Conclusions: Our findings suggest that the SIP does not appear to function effectively in a mixed dementia sample where there is increased potential for secondary gain. Additional concern is expressed regarding the overall likelihood of obtaining the SIP and subsequent inferential decisions related to obtaining an SIP. Future research should examine more optimal cut scores or alternative methods for more accurately classifying patients in different clinical contexts and patterns of impairment. PMID- 29471394 TI - hsa-let-7b-5p facilitates Mycobacterium tuberculosis survival in THP-1 human macrophages by Fas downregulation. AB - Tuberculosis continues to be one of the deadliest infectious diseases worldwide. MicroRNAs (miRNAs) are small non-coding entities that play critical role as post transcriptional regulators and are transcriptionally deregulated upon mycobacterial infection. In this study, we found significant upregulation of hsa let-7b-5p in Mycobacterium tuberculosis (MTB) infected THP-1 human macrophages. Concomitantly, we detected the reduced level of Fas protein, one of the targets of hsa-let-7b-5p, in MTB-infected THP-1 macrophages. Using luciferase assay, a direct interaction between hsa-let-7b-5p and the Fas 3?-untranslated region (3? UTR) was established. Inhibition of hsa-let-7b-5p augmented the apoptosis of THP 1 cells enabling enhanced clearance of MTB. Our findings suggest that hsa-let-7b 5p helps intracellular survival of MTB in THP-1 cells by downregulating Fas protein level. This highlights hsa-let-7b-5p as a potential therapeutic target for tuberculosis treatment. PMID- 29471395 TI - Origin and composition of cell-free DNA in spent medium from human embryo culture during preimplantation development. AB - STUDY QUESTION: What is the origin and composition of cell-free DNA in human embryo spent culture media? SUMMARY ANSWER: Cell-free DNA from human embryo spent culture media represents a mix of maternal and embryonic DNA, and the mixture can be more complex for mosaic embryos. WHAT IS KNOWN ALREADY: In 2016, ~300 000 human embryos were chromosomally and/or genetically analyzed using preimplantation genetic testing for aneuploidies (PGT-A) or monogenic disorders (PGT-M) before transfer into the uterus. While progress in genetic techniques has enabled analysis of the full karyotype in a single cell with high sensitivity and specificity, these approaches still require an embryo biopsy. Thus, non-invasive techniques are sought as an alternative. STUDY DESIGN, SIZE, DURATION: This study was based on a total of 113 human embryos undergoing trophectoderm biopsy as part of PGT-A analysis. For each embryo, the spent culture media used between Day 3 and Day 5 of development were collected for cell-free DNA analysis. In addition to the 113 spent culture media samples, 28 media drops without embryo contact were cultured in parallel under the same conditions to use as controls. In total, 141 media samples were collected and divided into two groups: one for direct DNA quantification (53 spent culture media and 17 controls), the other for whole genome amplification (60 spent culture media and 11 controls) and subsequent quantification. Some samples with amplified DNA (N = 56) were used for aneuploidy testing by next-generation sequencing; of those, 35 samples underwent single nucleotide polymorphism (SNP) sequencing to detect maternal contamination. Finally, from the 35 spent culture media analyzed by SNP sequencing, 12 whole blastocysts were analyzed by fluorescence in situ hybridization (FISH) to determine the level of mosaicism in each embryo, as a possible origin for discordance between sample types. PARTICIPANTS/MATERIALS, SETTING, METHODS: Trophectoderm biopsies and culture media samples (20 MUl) underwent whole-genome amplification, then libraries were generated and sequenced for an aneuploidy study. For SNP sequencing, triads including trophectoderm DNA, cell-free DNA, and follicular fluid DNA were analyzed. In total, 124 SNPs were included with 90 SNPs distributed among all autosomes and 34 SNPs located on chromosome Y. Finally, 12 whole blastocysts were fixed and individual cells were analyzed by FISH using telomeric/centromeric probes for the affected chromosomes. MAIN RESULTS AND THE ROLE OF CHANCE: We found a higher quantity of cell-free DNA in spent culture media co-cultured with embryos versus control media samples (P <= 0.001). The presence of cell-free DNA in the spent culture media enabled a chromosomal diagnosis, although results differed from those of trophectoderm biopsy analysis in most cases (67%). Discordant results were mainly attributable to a high percentage of maternal DNA in the spent culture media, with a median percentage of embryonic DNA estimated at 8%. Finally, from the discordant cases, 91.7% of whole blastocysts analyzed by FISH were mosaic and 75% of the analyzed chromosomes were concordant with the trophectoderm DNA diagnosis instead of the cell-free DNA result. LIMITATIONS, REASONS FOR CAUTION: This study was limited by the sample size and the number of cells analyzed by FISH. WIDER IMPLICATIONS OF THE FINDINGS: This is the first study to combine chromosomal analysis of cell free DNA, SNP sequencing to identify maternal contamination, and whole-blastocyst analysis for detecting mosaicism. Our results provide a better understanding of the origin of cell-free DNA in spent culture media, offering an important step toward developing future non-invasive karyotyping that must rely on the specific identification of DNA released from human embryos.

PMID- 29471396 TI - Involvement of Epigenetic Modifications of GABAergic Interneurons in Basolateral Amygdala in Anxiety-like Phenotype of Prenatally Stressed Mice. AB - Background: Prenatal stress is considered a risk factor for anxiety disorder. Downregulation in the expression of GABAergic gene, that is, glutamic acid decarboxylase 67, associated with DNA methyltransferase overexpression in GABAergic neurons has been regarded as a characteristic component of anxiety disorder. Prenatal stress has an adverse effect on the development of the basolateral amygdala, which is a key region in anxiety regulation. The aim of this study is to analyze the possibility of epigenetic alterations of GABAergic neurons in the basolateral amygdala participating in prenatal stress-induced anxiety. Methods: Behavioral tests were used to explore the prenatal stress induced anxiety behaviors of female adult mice. Real-time RT-PCR, western blot, chromatin immunoprecipitation, and electrophysiological analysis were employed to detect epigenetic changes of GABAergic system in the basolateral amygdala. Results: Prenatal stress mice developed an anxiety-like phenotype accompanied by a significant increase of DNA methyltransferase 1 and a reduced expression of glutamic acid decarboxylase 67 in the basolateral amygdala. Prenatal stress mice also showed the increased binding of DNA methyltransferase 1 and methyl CpG binding protein 2 to glutamic acid decarboxylase 67 promoter region. The decrease of glutamic acid decarboxylase 67 transcript was paralleled by an enrichment of 5 methylcytosine in glutamic acid decarboxylase 67 promoter regions. Electrophysiological study revealed the increase of postsynaptic neuronal excitability in the cortical-basolateral amygdala synaptic transmission of prenatal stress mice. 5-Aza-deoxycytidine treatment restored the increased synaptic transmission and anxiety-like behaviors in prenatal stress mice via improving GABAergic system. Conclusion: The above results suggest that DNA epigenetic modifications of GABAergic interneurons in the basolateral amygdala participate in the etiology of anxiety-like phenotype in prenatal stress mice. PMID- 29471397 TI - A Conceptual Framework: The Musical Self as a Unique Pathway to Outcomes in the Acute Pediatric Health Setting. AB - This article reports on a project at the Royal Children's Hospital Melbourne in which the music therapy team synthesized their practice and related theories to propose a new conceptual framework for music therapy in their acute pediatric setting. The impetus for the project was the realization that in the process of producing key statements about the non-musical benefits of music therapy, the cost was often the suppression of information about the patient's unique musical potential as the major (mediating) pathway from referral reason, to music therapy, and to effective outcomes. The purpose of the project was to articulate how this team of clinicians conceive of the patient's musical self as the major theoretical pathway for music therapy in an evidence-based acute medical setting. The clinicians' shared reflexive process across six months involved robust directed discussion, annotation of shared reading, and documentation of all engagement in words and diagrams. The outcome was a consensus framework including three constructs: the place of music in the life of the infant, child, and young people, Culture and Context, and Musical Manifestations. The constructs were tested in a clinical audit, and found to be robustly inclusive. In addition to the conceptual framework, this project serves to demonstrate a process by which clinical teams may reflect on their individual practice and theory together to create a consensus stance for the overall service they provide in the one setting. PMID- 29471398 TI - Reducing BW loss during lactation in sows: a meta-analysis on the use of a nonstarch polysaccharide-hydrolyzing enzyme supplement. AB - A meta-analysis was performed on eight trials, which included a total of 992 parity 1 to 8 lactating sows, to evaluate the effects of feeding xylanase which is the main enzyme activity present in the enzymatic complex (Rovabio Excel, Adisseo, France) supplement throughout lactation on the following sow performance factors: BW loss, feed intake, backfat depth, and piglet growth. Even a short period of enzyme supplementation during lactation led to a reduction in BW loss of approximately 3 kg per sow (P = 0.003). This reduction represented 1-2% of the BW of sows. This effect could be explained by an increase in feed energy intake and enhanced feed digestibility. Sows fed enzyme-supplemented diets exhibited greater DM, OM, and GE digestibilities (3.4, 3.9, and 4.2% increases, respectively; P < 0.001) than sows fed control diets. During lactation, sows lost from 19 to 25 kg of BW (i.e., approximately 10% of their BW), with a difference between parity groups (P < 0.001). Body reserve mobilization was decreased in sows fed enzyme-supplemented diets (-2.9 kg, P = 0.003), with a more pronounced effect in primiparous than multiparous sows when BW loss is expressed relative to total BW (-2.27 vs. -0.59%, respectively; P = 0.058). Enzyme supplementation also increased litter weight gain up to weaning, with a greater effect in litters from multiparous sows than those from primiparous sows (5.4 vs. 0.6 kg, respectively; P = 0.009). These results could be explained in part by the relationship between their NE intake and either variations in BW or litter weight gain (R2 = 0.51 and 0.49, respectively; P < 0.001). Finally, the meta-analysis suggests that there are differences in the partitioning of the NE intake between growth and milk production and in relation to the sow's parity or physiological status. Extra energy released by enzyme is used for one of these functions (i.e., body mobilization reduction or greater milk export for litter gain). PMID- 29471399 TI - From genome-wide association studies to Mendelian randomization: novel opportunities for understanding cardiovascular disease causality, pathogenesis, prevention, and treatment. AB - The Mendelian randomization approach is an epidemiological study design incorporating genetic information into traditional epidemiological studies to infer causality of biomarkers, risk factors, or lifestyle factors on disease risk. Mendelian randomization studies often draw on novel information generated in genome-wide association studies on causal associations between genetic variants and a risk factor or lifestyle factor. Such information can then be used in a largely unconfounded study design free of reverse causation to understand if and how risk factors and lifestyle factors cause cardiovascular disease. If causation is demonstrated, an opportunity for prevention of disease is identified; importantly however, before prevention or treatment can be implemented, randomized intervention trials altering risk factor levels or improving deleterious lifestyle factors needs to document reductions in cardiovascular disease in a safe and side-effect sparse manner. Documentation of causality can also inform on potential drug targets, more likely to be successful than prior approaches often relying on animal or cell studies mainly. The present review summarizes the history and background of Mendelian randomization, the study design, assumptions for using the design, and the most common caveats, followed by a discussion on advantages and disadvantages of different types of Mendelian randomization studies using one or more samples and different levels of information on study participants. The review also provides an overview of results on many of the risk factors and lifestyle factors for cardiovascular disease examined to date using the Mendelian randomization study design. PMID- 29471400 TI - Increased dietary protein or free amino acids supply for heat stress pigs: effect on performance and carcass traits. AB - Heat stress (HS) pigs reduce their voluntary feed intake (VFI) and ingestion of indispensable amino acids (AA). Increasing the dietary crude protein (CP) content may help to correct the reduced AA intake by HS pigs, but it may further increase their body heat load. Increasing the AA intake by adding free AA to the diet does not affect the heat load of HS pigs. Two 21-d experiments were conducted. In Exp. 1, 30 pigs (31.1 +/- 1.2 kg initial body weight) were used to determine the performance depression because of HS. Treatments were: thermo neutral pigs fed a 22% CP control diet (TN-C); HS pigs fed the control diet (HS-C); HS pigs fed a 14% CP, AA supplemented diet (HS-AA). HS pigs had lower ADG and Lys utilization efficiency, and consumed 20 and 25% less Lys and Thr, respectively, than the TN-C pigs (P < 0.05). In Exp. 2 (comparative slaughter), 25 pigs (33.6 +/- 0.65 kg initial body weight) were used to evaluate the effect of extra dietary AA either as protein-bound or free AA on the performance and carcass traits of HS pigs. Treatments were: control wheat-SBM-free Lys, Thr and Met diet (CON); diet with 30% more CP than CON (HSxP); diet added with free AA to contain at least 25% more of each AA than the recommended level (HSxAA). Ambient temperature (AT) ranged from 27.7 to 37.7 degrees C, and body temperature (39.9 to 41.2 degrees C) followed a similar daily pattern as the AT did. There was no dietary treatment effect on daily feed and NE intake (P > 0.10), but the Lys, Thr, and Met intake was higher in pigs fed the HSxP or HSxAA diets than in pigs fed the CON diet (P < 0.05). The daily weight gain (ADG) was not affected (P > 0.10) but G:F tended to be higher and the Lys utilization efficiency (ADG, g/g Lys intake) tended to be lower in HSxP pigs than in CON pigs (P < 0.10). The HSxAA pigs had higher ADG (P < 0.05), and tended to have higher weight of hot carcass and leg muscle, and the weight gain of hot carcass and leg muscle than the CON pigs (P < 0.10). The weight and daily weight gain of loin muscle was higher in the HSxAA than in the HSxP pigs (P < 0.05). Kidney weight and serum urea in HSxP pigs were higher than in CON and HSxAA pigs, but spleen weight was higher in HSxAA pigs than in CON and HSxP pigs (P < 0.05). These results confirm that HS reduces the VFI, and show that increased levels of AA either as free or protein-bound do not additionally reduce the VFI of HS pigs. These also show that extra free AA supply rather than protein-bound AA better ameliorate the reduced growth performance of HS pigs. PMID- 29471401 TI - Influence of Tree Size and Application Rate on Expression of Thiamethoxam in Citrus and Its Efficacy Against Diaphorina citri (Hemiptera: Liviidae). AB - Neonicotinoids are a key group of insecticides used to manage Diaphorina citri Kuwayama (Hemiptera: Liviidae), in Florida citrus. Diaphorina citri is the vector of Candidatus Liberibacter asiaticus, the presumed causal agent of huanglongbing, a worldwide disease of citrus. A two-season field study was conducted to evaluate the effect of tree size and application rate on the expression of thiamethoxam in young citrus following application to the soil. D. citri adult and nymph abundance was also correlated with thiamethoxam titer in leaves. Tree size and application rate each significantly affected thiamethoxam titer in leaf tissue. The highest mean thiamethoxam titer observed (33.39 ppm) in small trees (mean canopy volume = 0.08 m3) occurred after application of the high rate (0.74 g Platinum 75SG per tree) tested. There was a negative correlation between both nymph and adult abundance with increasing thiamethoxam titer in leaves. A concentration of 64.63 ppm thiamethoxam was required to reach a 1% probability of encountering a flush shoot with at least one adult D. citri, while 19.05 ppm was required for the same probability of encountering nymphs. The LC90 for the field population was 7.62 ppm thiamethoxam when administered through ingestion. Exposure to dosages as low as 7.62 ppm would likely result in sublethal exposure of some proportion of the population, which could exacerbate resistance development. Based on our results, subsequent work should investigate the use of neonicotinoids by foliar rather than soil application to maintain the chemical class in future insecticide management programs in Florida citrus. PMID- 29471402 TI - A Review of Sclerodermus Latreille, 1809 (Hymenoptera: Bethylidae) Infestations and Report of the First Case in North America North of Mexico. AB - Sclerodermus Latreille, 1809 (Hymenoptera: Bethylidae), are parasitoids of wood boring beetle larvae that can co-infest furniture and homes attacked by such larvae. This can result in the human inhabitants receiving stings from adult female wasps as they wander in search of new hosts. Herein, I report the first infestation of Sclerodermus macrogaster (Ashmead, 1887) of a home in North America and provide a review of Sclerodermus biology and clinical signs relevant to their pestiferous nature. PMID- 29471403 TI - Influence of distiller's dried grains with solubles on ram lamb growth and reproductive traits. AB - The hypothesis of this experiment was that increasing the inclusion level of distiller's dried grains with solubles (DDGS) in the diets would decrease semen quality but have no negative effects on growth performance. Following the removal of DDGS from the diet, it was hypothesized that the ram lambs would recover and become reproductively sound, independent of treatment. To test this hypothesis, Suffolk and Hampshire ram lambs (n = 112) were allocated to 4 treatments (n = 4 pens per treatment; 7 rams per pen) in a completely randomized design. Dietary treatments were 60% corn, 25% oats, and 15% commercial lamb pellet (CON), 15% of the ration as DDGS substituted for corn (% DM basis; 15DDGS), 30% of the ration as DDGS substituted for corn (% DM basis; 30DDGS), and 45% of the ration as DDGS substituted for corn (% DM basis; 45DDGS). Lambs were fed for 112 d on their respective treatment, after which they were placed on the CON ration until day 168. Lambs were weighed on consecutive d at the beginning (days 0 and 1) and end (days 167 and 168) of the study. Scrotal circumference was measured on all lambs on days 84, 112, 140, and 168. Semen samples were collected on a subset of 64 rams (4 rams per pen) to evaluate semen quality on days 84, 112, 140, and 168. Blood samples were collected on the same subset of rams every 14 d throughout the study. A quadratic effect on BW on day 112 and overall BW (P = 0.03 and P = 0.005, respectively), ADG on day 112 and overall ADG (P = 0.02 and P = 0.02, respectively), DMI (P = 0.007) on day 112, and a cubic effect (P = 0.05) for overall G:F were observed. Overall and day 168 scrotal circumference had a quadratic (P = 0.05) response. A linear increase in spermatozoa concentration on day 168 was observed (P = 0.03) as DDGS concentration increased in the treatment diets, although rams in this stage of the study were no longer receiving DDGS. Overall, testosterone concentrations exhibited a linear decrease (P = 0.005) as DDGS increased in the diet. The linear increase (P = 0.04) on day 168 in morphologically normal sperm as DDGS increased in the diets indicated that all rams, regardless of treatment, would have passed a reproductive soundness exam. In the current study, no negative effects were observed in lamb feedlot or reproductive traits due to increasing DDGS in the diet, indicating that DDGS may be included at levels up to 45% of growing lamb diets.

PMID- 29471406 TI - Multiobjective multifactor dimensionality reduction to detect SNP-SNP interactions. AB - Motivation: Single-nucleotide polymorphism (SNP)-SNP interactions (SSIs) are popular markers for understanding disease susceptibility. Multifactor dimensionality reduction (MDR) can successfully detect considerable SSIs. Currently, MDR-based methods mainly adopt a single-objective function (a single measure based on contingency tables) to detect SSIs. However, generally, a single measure function might not yield favorable results due to potential model preferences and disease complexities. Approach: This study proposes a multiobjective MDR (MOMDR) method that is based on a contingency table of MDR as an objective function. MOMDR considers the incorporated measures, including correct classification and likelihood rates, to detect SSIs and adopts set theory to predict the most favorable SSIs with cross-validation consistency. MOMDR enables simultaneously using multiple measures to determine potential SSIs. Results: Three simulation studies were conducted to compare the detection success rates of MOMDR and single-objective MDR (SOMDR), revealing that MOMDR had higher detection success rates than SOMDR. Furthermore, the Wellcome Trust Case Control Consortium dataset was analyzed by MOMDR to detect SSIs associated with coronary artery disease. Availability and implementation: MOMDR is freely available at https://goo.gl/M8dpDg. Supplementary information: Supplementary data are available at Bioinformatics online. PMID- 29471405 TI - Socioeconomic and Human Behavioral Factors Associated With Aedes aegypti (Diptera: Culicidae) Immature Habitat in Tucson, AZ. AB - Aedes aegypti (L.; Diptera: Culicidae) has been established in the southwestern United States for several decades, but relationships between humans and mosquitoes in this arid region are not well-characterized. In August 2012, the outdoor premises of 355 houses within 20 neighborhoods in Tucson, Arizona were surveyed for containers that could provide larval habitat for Ae. aegypti mosquitoes. At the same time, a knowledge, attitudes and practices (KAP) questionnaire was administered to a resident of each house surveyed for immature mosquitoes. The KAP questionnaire assessed respondents' knowledge and concerns about vector-borne illnesses as well as practices they used to avoid mosquitoes. Of the houses surveyed, 91% had at least one container present, and 64% had at least one container with standing water. On average, each house had 2.2 containers with water at the time of the survey. The overall House Index (proportion of premises surveyed with at least one container with Ae. aegypti immatures present) was 13%. Based on questionnaire responses, there was a significant positive association between the number of residents in the home and the odds of finding Ae. aegypti positive containers on the premises, while household income showed a significant negative association. The reported frequency of checking for standing water was also significantly associated with the odds of finding immatures, although the nature of this association was ambiguous. Flower pots were the principal type of container with Ae. aegypti larvae. These findings show that larval habitat is widely available even in an arid environment and city with good housing and sanitation infrastructure. PMID- 29471407 TI - Plasma copeptin as a predictor of kidney disease. AB - Background: Plasma copeptin, a marker of vasopressin, is associated with renal function decline in the general population. Our aim was to study the links between elevated copeptin and future risk of kidney disease. Methods: Copeptin was measured in a sample of the Malmo Preventive Project (MPP) Reinvestigation (n = 5158) and in the Malmo Diet and Cancer Cardiovascular Cohort (MDC-CC) (n = 5162). According to national registers, 89 subjects in MPP and 180 in MDC-CC developed chronic kidney disease (CKD) during follow-up (8.7 and 19.6 years, respectively). Results: After multivariate adjustment (gender, age, body mass index, smoking status, estimated glomerular filtration rate, prevalent diabetes, systolic blood pressure and prevalent antihypertensive treatment), copeptin (beta coefficient per 1 standard deviation increment of ln copeptin) was independently associated with increased risk of CKD during follow-up in both cohorts (MPP: (HR) 1.46, 95% confidence interval (CI) 1.18-1.80, P < 0.001; MDC-CC: HR 1.25, 95% CI 1.02-1.54, P = 0.03) among subjects free from prevalent kidney disease at baseline. Furthermore, in MPP, elevated copeptin predicted a specified diagnosis of kidney disease other than CKD (HR 1.31, 95% CI 1.08-1.59, P = 0.006) after multivariate adjustment. In a corresponding analysis in MDC-CC, copeptin was associated with a 10% increased risk, which, however, was non-significant (P = 0.25). A meta-analysis of the MPP and MDC-CC data showed significant association between elevated copeptin and a specified diagnosis of kidney disease other than CKD (HR 1.18, 95% CI 1.05-1.34, P = 0.008). Conclusion: An increased level of copeptin independently predicts development of both CKD and other specified kidney diseases, suggesting that copeptin can be used to identify individuals at risk for kidney disease development. PMID- 29471408 TI - Thiazole derivatives act on virulence factors of Cryptococcus spp. AB - Cryptococcosis is an opportunistic or primary fungal infection considered to be the most prevalent fatal fungal disease worldwide. Owing to the limited number of available drugs, it is necessary to search for novel antifungal compounds. In the present work, we assessed the antifungal efficacy of three thiazole derivatives (1, 2, and 3). We conducted in vitro and in vivo assays to investigate their effects on important virulence factors, such as capsule and biofilm formation. In addition, the phagocytosis index of murine macrophages exposed to compounds 1, 2, and 3 and the in vivo efficacy of 1, 2, and 3 in Galleria mellonella infected with Cryptococcus spp. were evaluated. All compounds exhibited antifungal activity against biofilms and demonstrated a reduction in biofilm metabolic activity by 43-50% for C. gattii and 26-42% for C. neoformans. Thiazole compounds promoted significant changes in the capsule thickness of C. gattii compared to that of C. neoformans. Further examination of these compounds suggests that they can improve the phagocytosis process of peritoneal murine macrophages in vitro, causing an increase in the phagocytosis rate. Survival percentage was examined in the invertebrate model Galleria mellonella larvae, and only compound 3 could increase the survival at doses of 5 mg/kg after infection with C. gattii (P = .0001) and C. neoformans (P = .0007), similar to fluconazole at 10 mg/kg. The results demonstrated that thiazole compounds, mainly compound 3, have potential to be used for future studies in the search for new therapeutics for cryptococcosis.

AB - Objective: The empirical identification of risk factors associated with sport related concussion (SRC) may improve the management of student-athletes. The current study attempted to identify and quantify bio-cognitive risk factors associated with sustaining a SRC. Methods: Cross-sectional ambispective study; level of evidence, 3. Neurocognitive testing of 12,320 middle school, high school and collegiate athletes was completed at preseason baseline and post-SRC. Univariate and multivariable logistic regressions were used to determine which pre-injury variables accurately predicted the occurrence of SRC. A quantitative risk score for each variable was developed. Results: Five of 13 variables maintained significance in the multivariable model with the associated weighted point scores: SRC history (21), prior headache treatment (6), contact sport (5), youth level of play (7), and history of ADHD/LD (2). Six stratified groups were formed based on probability of SRC, which produced an area under the curve (AUC) of 0.71 (95% CI 0.69-0.72, p < .001). Though the model was a significant predictor of SRC (X2 = 1,112.75, p < .001), the effect size was small and accounted for only 16% of the overall variance. Conclusions: An initial aggregate model of weighted bio-cognitive factors associated with increased odds of sustaining a SRC was developed. Previously validated factors were confirmed, yet a large source of variance remained unexplained. These findings emphasize the need to expand the host factors studied when assessing SRC risk, and that the existing, empirically based bio-cognitive factors do not adequately quantify the risk of SRC. PMID- 29471411 TI - Mechanisms Underpinning the Polypharmacy Effects of Medications in Psychiatry. AB - Background: Bipolar disorder is a mental health condition with progressive social and cognitive function disturbances. Most patients' treatments are based on polypharmacy, but with no biological basis and little is known of the drugs' interactions. The aim of this study was to analyze the effects of lithium, valproate, quetiapine, and lamotrigine, and the interactions between them, on markers of inflammation, bioenergetics, mitochondrial function, and oxidative stress in neuron-like cells and microglial cells. Methods: Neuron-like cells and lipopolysaccharide-stimulated C8-B4 cells were treated with lithium (2.5 mM), valproate (0.5 mM), quetiapine (0.05 mM), and lamotrigine (0.05 mM) individually and in all possible combinations for 24 h. Twenty cytokines were measured in the media from lipopolysaccharide-stimulated C8-B4 cells. Metabolic flux analysis was used to measure bioenergetics, and real-time PCR was used to measure the expression of mitochondrial function genes in neuron-like cells. The production of superoxide in treated cells was also assessed. Results: The results suggest major inhibitory effects on proinflammatory cytokine release as a therapeutic mechanism of these medications when used in combination. The various combinations of medications also caused overexpression of PGC1alpha and ATP5A1 in neuron-like cells. Quetiapine appears to have a proinflammatory effect in microglial cells, but this was reversed by the addition of lamotrigine independent of the drug combination. Conclusion: Polypharmacy in bipolar disorder may have antiinflammatory effects on microglial cells as well as effects on mitochondrial biogenesis in neuronal cells. PMID- 29471412 TI - Interactions between the concentration of non-starch polysaccharides in wheat and the addition of an enzyme mixture in a broiler digestibility and performance trial. AB - Two broiler trials were designed to investigate the relationship between the concentration of non-starch polysaccharides (NSP) in wheat and 1) its nutritional value for broilers and 2) the efficacy of exogenous enzymes. In a balance trial, diets were formulated with 3 wheat cultivars (Rustic and Viscount-medium NSP, Centenaire-high NSP) and were tested with or without the addition of an exogenous enzyme mixture. The diets were fed to 144 male Ross 308 broiler chickens housed in digestibility cages. Total tract nutrient digestibilities and AMEn were measured from 18 to 22 d of age. In a performance trial, diets were formulated with wheat (medium NSP diet) or with wheat mixed with rye and barley (high NSP diet) and were tested with or without the addition of an exogenous enzyme mixture. The diets were fed to 960 male Ross 308 broilers housed in pens and broiler performance during starter, grower and finisher periods was measured.In the balance trial, wheat cultivar did not affect nutrient digestibility or AMEn. Enzyme addition caused a significant increase in nutrient digestibilities and AMEn for the diet formulated with the high NSP wheat Centenaire only. In the performance trial, feeding the high NSP diet resulted in a higher feed conversion ratio and lower final body weight compared to the medium NSP diet. The largest improvements by enzyme addition were observed in the high NSP diet.In conclusion, the study was not able to show a consistent relationship between the NSP concentration of wheat and its nutritional value, but did demonstrate that the effect of an enzyme mixture on nutrient digestibility or broiler performance depends upon the NSP concentration in the diet. PMID- 29471414 TI - Examination of a Managed Pollinator Strategy for Almond Production Using Apis mellifera (Hymenoptera: Apidae) and Osmia lignaria (Hymenoptera: Megachilidae). AB - Pollination services provided by managed bees are essential for California almond (Prunus dulcis Mill.; Rosales: Rosaceae) production. Currently, pollination needs are met by rented or owned Apis mellifera L. (Hymenoptera: Apidae; honey bee) colonies. Excessive demand on a challenged A. mellifera industry to provide strong colonies in early spring has caused sharp increases in rental prices over the past decade, inviting the consideration of alternative pollinators in addition to, or in place of, A. mellifera. Osmia lignaria Say (Hymenoptera: Megachilidae; the blue orchard bee) is an excellent pollinator of fruit and nut trees, but its pollination impacts when used in tandem with A. mellifera have yet to be evaluated in commercial almond orchards. A 2-yr study was conducted in California orchards to compare almond pollination and production using A. mellifera as sole pollinator to an alternative practice of adding O. lignaria as a co-pollinator with A. mellifera. Almond orchard managerial decisions, such as for pesticide use and irrigation intensity, vary between almond growing regions because of local climates. Therefore, both north-central and southern sites of California's San Joaquin Valley are represented. We compared bee visitation, nut set, and nut yield between orchards and between tree rows within orchards. Also, O. lignaria reproductive success was recorded to assure that these bees remained in the orchards as pollinators and to assess the ability to sustain these bees under regional orchard conditions. We demonstrated that augmenting large commercial almond orchards with O. lignaria can significantly increase nut set and sometimes nut yield in both regions evaluated. PMID- 29471413 TI - Combined cistrome and transcriptome analysis of SKI in AML cells identifies SKI as a co-repressor for RUNX1. AB - SKI is a transcriptional co-regulator and overexpressed in various human tumors, for example in acute myeloid leukemia (AML). SKI contributes to the origin and maintenance of the leukemic phenotype. Here, we use ChIP-seq and RNA-seq analysis to identify the epigenetic alterations induced by SKI overexpression in AML cells. We show that approximately two thirds of differentially expressed genes are up-regulated upon SKI deletion, of which >40% harbor SKI binding sites in their proximity, primarily in enhancer regions. Gene ontology analysis reveals that many of the differentially expressed genes are annotated to hematopoietic cell differentiation and inflammatory response, corroborating our finding that SKI contributes to a myeloid differentiation block in HL60 cells. We find that SKI peaks are enriched for RUNX1 consensus motifs, particularly in up-regulated SKI targets upon SKI deletion. RUNX1 ChIP-seq displays that nearly 70% of RUNX1 binding sites overlap with SKI peaks, mainly at enhancer regions. SKI and RUNX1 occupy the same genomic sites and cooperate in gene silencing. Our work demonstrates for the first time the predominant co-repressive function of SKI in AML cells on a genome-wide scale and uncovers the transcription factor RUNX1 as an important mediator of SKI-dependent transcriptional repression. PMID- 29471415 TI - Blue and Black Cloth Targets: Effects of Size, Shape, and Color on Stable Fly (Diptera: Muscidae) Attraction. AB - Stable fly management is challenging because of the fly's dispersal behavior and its tendency to remain on the host only while feeding. Optically attractive traps have been used to survey and sometimes reduce adult populations. Insecticide treated blue and black cloth targets developed for tsetse fly management in Africa were found to be attractive to stable flies in the United States, and various evaluations were conducted in Louisiana and Florida. Tests using untreated targets were designed to answer questions about configuration, size, and color relative to efficacy and stability in high winds. Studies with electric grid targets and with targets paired with Olson traps showed cloth target color attraction in the following decreasing order: black > blue-black > blue. A solid black target is easier to make than a blue-black target because no sewing is involved. Attraction was not affected when flat 1-m2 targets were formed into cylinders, despite the limited view of the blue and black colors together. There was no reduction in attraction when the 1-m2 cylindrical targets were compared with smaller (63 * 30 cm high) cylindrical targets. In addition, there was no difference in attraction between the small blue-black, blue, and black targets. Significance of findings and implications of potential uses for treated targets are discussed. Target attraction was indicated by the numbers of stable flies captured on an Olson sticky trap placed 30 cm from the target. Although this system is adequate for field research, it greatly underestimates the actual numbers of stable flies attracted to treated targets. PMID- 29471417 TI - A study of circulating microRNAs identifies a new potential biomarker panel to distinguish aggressive prostate cancer. AB - Prostate cancer is one of the most common cancers in men worldwide. Currently available diagnostic and prognostic tools for this disease, such as prostate specific antigen, suffer from lack of specificity and sensitivity, resulting in over- and misdiagnosis. Hence, there is an urgent need for clinically relevant biomarkers capable of distinguishing between aggressive and nonaggressive forms of prostate cancer to aid in stratification, management and therapeutic decisions. To address this unmet need, we investigated the patterns of expression of a panel of 68 plasma-derived microRNAs (miRNAs) in a cohort of African American (AA) and European American (EA) prostate cancer patients (n = 114). miRNA qPCR results were analyzed using in-depth statistical methods, and a bioinformatics analysis was conducted to identify potential targets of the differentially expressed miRNAs. Our data demonstrate that a new previously unreported circulating miRNA signature consisting of a combination of interacting miRNAs (miR-17/miR-192) and an independent miRNA (miR-181a) are capable of segregating aggressive and nonaggressive prostate cancer in both AA and EA patients. The interacting miRNAs outperformed independent miRNAs in identifying aggressiveness. Our results suggest that these circulating miRNAs may constitute novel biomarkers of prostate cancer aggressiveness in both races and warrant further investigation. PMID- 29471418 TI - Skin-specific training experience of workers assessed for contact dermatitis. AB - Background: Contact dermatitis is a common and preventable work-related disease. Skin-specific training may be effective for preventing occupational contact dermatitis, but little information is available regarding actual workplace training and its effectiveness. Aims: To describe workplace skin-specific training among workers with suspected contact dermatitis. Methods: Patch test patients being assessed for suspected contact dermatitis at an occupational health clinic in Toronto, Canada, completed a questionnaire on training experiences, workplace characteristics, exposures and skin protection practices. Results: Of 175 patients approached, 122 (71%) workers completed questionnaires. Many (80%) had received general occupational health and safety and hazardous materials training (76%). Fewer (39%) received skin-specific training. Of those with work-related contact dermatitis, 52% did not receive skin-specific training. Skin-specific training was commonly provided by health and safety professionals or supervisors using video, classroom and online techniques. Content included glove use, exposure avoidance and hand washing information. Workers that received skin-specific training found it memorable (87%), useful (85%) and common sense in nature (100%). Conclusions: This study indicates gaps in workplace training on skin disease prevention for workers with contact dermatitis. Workers perceived skin-specific training to be useful. Understanding worker training experiences is important to prevention programme development and reducing work-related skin disease. PMID- 29471416 TI - Anti-interleukin 6 receptor tocilizumab in refractory uveitis associated with Behcet's disease: multicentre retrospective study. AB - Objective: To assess the efficacy of tocilizumab (TCZ) in refractory uveitis of Behcet's disease (BD). Methods: Multicentre study of patients with BD-associated uveitis. Patients were refractory to conventional and biologic immunosuppressive drugs. The main outcome measures were intraocular inflammation, macular thickness, visual acuity and corticosteroid-sparing effects. Results: We studied 11 patients (7 men) (20 affected eyes); median age 35 years. Uveitis was bilateral in nine patients. The patterns of ocular involvement were panuveitis (n = 8, with retinal vasculitis in 4), anterior uveitis (n = 2) and posterior uveitis (n = 1). Cystoid macular oedema was present in seven patients. The clinical course was recurrent (n = 7) or chronic (n = 4). Before TCZ, patients had received systemic corticosteroids, conventional immunosuppressants and the following biologic agents: adalimumab (n = 8), infliximab (n = 4), canakimumab (n = 1), golimumab (n = 3), etanercept (n = 1). TCZ was used as monotherapy or combined with conventional immunosuppressants at 8 mg/kg/i.v./4 weeks (n = 10) or 162 mg/s.c./week (n = 1). At TCZ onset the following extraocular manifestations were present: oral and/or genital ulcers (n = 7), arthritis (n = 4), folliculitis/pseudofolliculitis (n = 4), erythema nodosum (n = 2), livedo reticularis (n = 1) and neurological involvement (n = 2). TCZ yielded rapid and maintained improvement in all ocular parameters of the patients, with complete remission in eight of them. However, this was not the case for the extraocular manifestations, since TCZ was only effective in three of them. After a mean (s.d.) follow-up of 9.5 (8.05) months, TCZ was withdrawn in two cases, due to a severe infusion reaction and arthritis impairment, respectively. Conclusion: TCZ could be a therapeutic option in patients with BD and refractory uveitis. PMID- 29471419 TI - True-lumen and false-lumen diameter changes in the downstream aorta after frozen elephant trunk implantation. AB - OBJECTIVES: To evaluate early and mid-term clinical outcomes and to assess the potential of the frozen elephant trunk technique to induce remodelling of downstream aortic segments in acute and chronic thoracic aortic dissections. METHODS: Over a 4-year period, 65 patients (48 men, aged 61 +/- 12 years) underwent total aortic arch replacement using the frozen elephant trunk technique for acute (n = 31) and chronic (n = 34) thoracic aortic dissections at our institution. We assessed diameter changes at 3 levels: the L1 segment at the stent graft level; the L2 segment at the thoraco-abdominal transition level and the L3 segment at the coeliac trunk level. True-lumen (TL) and false-lumen (FL) diameter changes were assessed at each level. RESULTS: Fifty-six percent of patients had already undergone previous aortic or cardiac surgery. In-hospital mortality was 6%. Symptomatic spinal cord injury was not observed in this series. During a mean follow-up of 12 +/- 12 months, late death was observed in 6% of patients. Aortic reinterventions in downstream aortic segments were performed in 28% at a mean of 394 +/- 385 days. TL expansion and FL shrinkage were measured in all segments and were observed at each level. This effect was the most pronounced at the level of the stent graft in patients with chronic aortic dissection, TL diameter increased from 15 +/- 17 mm before surgery to 28 +/- 2 mm (P = 0.001) after 2 years, and the FL diameter decreased from 40 +/- 11 mm before surgery to 32 +/- 17 mm (P = 0.026). CONCLUSIONS: The frozen elephant trunk technique is associated with an excellent clinical outcome in a complex cohort of patients, and also effectively induces remodelling in downstream aortic segments in acute and chronic thoracic aortic dissections. The need for secondary interventions in downstream segments, which mainly depends on the extent of the underlying disease process, remains substantial. Further studies are required to assess the long term outcome of this approach. PMID- 29471420 TI - Ethics, effectiveness and population health information interventions: a Canadian analysis. AB - Population health information interventions (PHIIs) use information in efforts to promote health. PHIIs may push information to a target audience (communication), pull information from the public (surveillance), or combine both in a bidirectional intervention. Although PHIIs have often been framed as non-invasive and ethically innocuous, in reality they may be intrusive into people's lives, affecting not only their health but their senses of security, respect, and self determination. Ethical acceptability of PHIIs may have impacts on intervention effectiveness, potentially giving rise to unintended consequences. This article examines push, pull, and bidirectional PHIIs using empirical data from an ethnographic study of young mothers in Greater Vancouver, Canada. Data were collected from October 2013 to December 2014 via naturalistic observation and individual interviews with 37 young mothers ages 16-22. Transcribed interviews and field notes were analyzed using inductive qualitative thematic analysis. Both push and pull interventions were experienced as non-neutral by the target population, and implementation factors on a structural and individual scale affected intervention ethics and effectiveness. Based on our findings, we suggest that careful ethical consideration be applied to use of PHIIs as health promotion tools. Advancing the 'ethics of PHIIs' will benefit from empirical data that is informed by information and computer science theory and methods. Information technologies, digital health promotion services, and integrated surveillance programs reflect important areas for investigation in terms of their effects and ethics. Health promotion researchers, practitioners, and ethicists should explore these across contexts and populations. PMID- 29471421 TI - Class 3 semaphorins modulate the invasive capacity of rheumatoid arthritis fibroblast-like synoviocytes. AB - Objective: Class 3 semaphorins regulate diverse cellular processes relevant to the pathology of RA, including immune modulation, angiogenesis, apoptosis and invasive cell migration. Therefore, we analysed the potential role of class 3 semaphorins in the pathology of RA. Methods: Protein and mRNA expression in RA synovial tissue, SF and fibroblast-like synoviocytes (FLS) were determined by immunoblotting and quantitative PCR (qPCR). RA FLS migration and invasion were determined using wound closure and transwell invasion assays, respectively. PlexinA1, neuropilin-1 and neuropilin-2 expression was knocked down using small interfering RNA (siRNA). Activation of FLS intracellular signalling pathways was assessed by immunoblotting. Results: mRNA expression of semaphorins (Sema)3B, Sema3C, Sema3F and Sema3G was significantly lower in the synovial tissue of early arthritis patients at baseline who developed persistent disease compared with patients with self-limiting disease after 2 years follow-up. Sema3B and Sema3F expression was significantly lower in arthritis patients fulfilling classification criteria for RA compared with those who did not. FLS expression of Sema3A was induced after stimulation with TNF, IL-1beta or lipopolysaccharides (LPS), while Sema3B and Sema3F expression was downregulated. Exogenously applied Sema3A induced the migration and invasive capacity of FLS, while stimulation with Sema3B or Sema3F reduced spontaneous FLS migration, and platelet-derived growth factor induced cell invasion, effects associated with differential regulation of MMP expression and mediated by the PlexinA1 and neuropilin-1 and -2 receptors. Conclusion: Our data suggest that modulation of class 3 semaphorin signaling could be a novel therapeutic strategy for modulating the invasive behaviour of FLS in RA. PMID- 29471422 TI - Phylogenetic analysis of Histoplasma capsulatum var duboisii in baboons from archived formalin-fixed, paraffin embedded tissues. AB - Histoplasma capsulatum var. duboisii (Hcd) infections have been well documented to cause chronic granulomatous disease, mainly involving the skin of baboons and humans in African countries primarily. This retrospective study classified the subspecies of Histoplasma and developed a phylogenetic tree utilizing DNA sequences extracted from formalin-fixed, paraffin embedded (FFPE) tissues from 9 baboons from a research colony in Texas histologically diagnosed with Hcd. Based on sequence analysis of ITS-2, Tub-1, and ARF, Hcd isolated from the archived samples closely aligns with the African clade and has 88% sequence homology with a sample isolated from an individual in Senegal. PMID- 29471423 TI - Predictive Models of Cognitive Fatigue in Multiple Sclerosis. AB - Objective: Cognitive fatigue (CF) can be defined as decreased performance with sustained cognitive effort. The present study examined the interrelatedness of disease severity, fatigue, depression, and sleep quality in order to evaluate their predictive roles of CF in MS. Four theoretical models examining these variables were assessed. Methods: Fifty-eight individuals with a diagnosis of MS were recruited. CF was measured by examining last third versus first third performance on the Paced Auditory Serial Addition Test (PASAT). The PASAT and self-report measures of fatigue, depression, and sleep quality were administered. Path analysis was used to evaluate each of the models. Results: CF was correlated only with depression (r = .362, p = .006) and sleep quality (r = .433, p = .001). Sleep quality was the greatest significant independent predictor of CF (beta = .433, t(1,55) = 3.53, p < .001), accounting for 17.3% of the total variance. The best fitting model showed sleep quality as the largest contributor to CF; however, depression played a smaller predictive role. Furthermore, depression emerged as the strongest predictor of sleep quality and fatigue. Disease severity weakly predicted depression. Conclusions: Sleep quality is the most significant predictor of CF in MS. As such, sleep quality may be a treatable cause of CF. Sleep quality itself, however, accounted for only 17.3% of the variance in CF suggesting that other variables which were not formally assessed in this sample (e.g., anxiety, etc.) may also play a predictive role. Follow-up studies should evaluate how results may differ with a larger sample size. PMID- 29471424 TI - Predicting user adherence to behavioral eHealth interventions in the real world: examining which aspects of intervention design matter most. AB - Existing frameworks have identified a range of intervention design features that may facilitate adherence to eHealth interventions; however, empirical data are lacking on whether intervention design features can predict user adherence in the real world-where the public access available tools-and whether some design aspects of behavioral eHealth interventions are more important than others in predicting adherence. This study examined whether intervention design qualities predict user adherence to behavioral eHealth interventions in real-world use and which qualities matter the most. We correlated the online activities of users of 30 web-based behavioral interventions-collected from a proprietary data set of anonymized logs from consenting users of Microsoft Internet Explorer add-on-with interventions' quality ratings obtained by trained raters prior to empirical examination. The quality ratings included: Usability, Visual Design, User Engagement, Content, Therapeutic Persuasiveness (i.e., persuasive design and incorporation of behavior change techniques), and Therapeutic Alliance. We found Therapeutic Persuasiveness (i.e., the incorporation of persuasive design/behavior change principles) to be the most robust predictor of adherence (i.e., duration of use, number of unique sessions; 40 <= rs <= .58, ps <= .005), explaining 42% of the variance in user adherence in our regression model. Results indicated up to six times difference in the percentage of users utilizing the interventions for more than a minimum amount of time and sessions based on Therapeutic Persuasiveness. Findings suggest the importance of persuasive design and behavior change techniques incorporation during the design and evaluation of digital behavioral interventions. PMID- 29471426 TI - Isolation, characterization, and antibiotic sensitivity assessment of Gallibacterium anatis biovar haemolytica, from diseased Egyptian chicken flocks during the years 2013 and 2015. AB - Gallibacterium anatis biovar haemolytica constitutes a part of the normal microflora in the upper respiratory and genital tracts of healthy chickens, but it is also associated with different pathological conditions. In the current study, 102 commercial chicken flocks suffering from respiratory disease and/or drop in egg production were investigated for the presence of G. anatis during 2013 and 2015. These flocks comprised 8 breeder, 32 layer, and 62 broiler flocks. By culture method, 20 flocks were found positive: one isolate derived from broiler breeders, 6 isolates from layers, and 13 isolates from broilers. G. anatis biovar haemolytica was identified by phenotyping and PCR. Additionally, partial genome sequencing of 11 isolates (5 layer isolates of 2013 and 6 broiler isolates of 2015) based on 16S rRNA and 23S rRNA gene sequences was performed and revealed 96.5% to 100% genetic relatedness. Antibiotic sensitivity of these isolates revealed that the 2013 isolates were highly susceptible to florfenicol while the isolates of 2015 were highly susceptible to cefotaxime. Gallibacterium anatis biovar haemolytica is a newly introduced bacteria in Egypt causing salpingitis, peritonitis, drop in egg production, and/or respiratory signs. PMID- 29471425 TI - FOXL2C134W-Induced CYP19 Expression via Cooperation With SMAD3 in HGrC1 Cells. AB - Germline knockout studies in female mice demonstrated an essential role for forkhead box L2 (FOXL2) in early follicle development, whereas an inducible granulosa cell (GC)-specific deletion of Foxl2 in adults has shown ovary-to testis somatic sex reprogramming. In women, over 120 different germline mutations in the FOXL2 gene have been shown to cause blepharophimosis/ptosis/epicantus inversus syndrome associated with or without primary ovarian insufficiency. By contrast, a single somatic mutation (FOXL2C134W) accounts for almost all adult type GC tumors (aGCTs). To test the hypothesis that FOXL2C134W differentially regulates the expression of aGCT markers, we investigated the effect of FOXL2C134W on inhibin B and P450 aromatase expression using a recently established human GC line (HGrC1), which we now show to bear two normal alleles of FOXL2. Neither FOXL2wt nor FOXL2C134W regulate INHBB messenger RNA (mRNA) expression. However, FOXL2C134W selectively displays a 50-fold induction of CYP19 mRNA expression dependent upon activin A. Mechanistically, the CYP19 promoter is activated in a similar way by FOXL2C134W interaction with SMAD3, but not by FOXL2wt. SMAD2 had no effect. Moreover, FOXL2C134W interactions with SMAD3 and with the FOX binding element located at -199 bp upstream of the ATG initiation codon of CYP19 are more sustainable than FOXL2wt. Thus, FOXL2C134W potentiates CYP19 expression in HGrC1 cells via enhanced recruitment of SMAD3 to a proximal FOX binding element. These findings may explain the pathophysiology of estrogen excess in patients with aGCT. PMID- 29471427 TI - Health and Work in Women and Men in the Welding and Electrical Trades: How Do They Differ? AB - Objectives: There is little information on how work tasks, demands, and exposures differ between women and men in nominally the same job. This is critical in setting workplace standards that will protect the health of both men and those women moving into less traditional work roles. Information used in setting standards is currently based almost entirely on male workers. This paper describes differences in work and health, and the relation between them, in women and men who have undergone the same trade training for the welding or electrical trades. Method: Four cohorts were established. Two were women across Canada in the welding and electrical trades who had been in an apprenticeship since 2005. Cohorts of men in the same trades during the same period were established in the province of Alberta, Canada. Participants completed a baseline questionnaire at recruitment and were followed up every 6 months to collect detailed information on work carried out and on their health and habits. At the end of the study (up to 5 years for women and up to 3 years for men), the cohort members completed a final questionnaire including questions on mental health, harassment, and gender. Results: The four cohorts comprised 1001 welders (447 female; 554 male) and 885 in the electrical trades (438 female; 447 male). Follow-up information was available for 89%. Women were more likely than men to have had some post secondary education before starting their trade and were less likely to be living as married or to have a child. More welders smoked, and more men were heavy drinkers. At recruitment, more welders than those in the electrical trades reported rhinitis (sneezing and runny nose), depression, and anxiety. Female welders reported more depression (38%) than male welders (30%), compared to 24% in the electrical trades. At first follow-up, new-onset shoulder pain was more frequent in men and new-onset asthma or wheezing in welders. Within each trade, women reported less variety in tasks. Women welders were less likely to be employed in construction than men, and women were less likely to become industrial electricians. Overall, 54% of women and 46% of men reported never using respiratory protection when welding. In the end-of-study questionnaires received to date, 49% reported bullying or harassment during the apprenticeship, with higher proportions in welding than electrical trades and in women compared with men. Such harassment was reflected in higher anxiety and depression scores. Conclusions: This is the first report on these four cohorts and demonstrates the capacity for detailed analysis of the differences in exposure and new-onset occupationally related ill-health. While women and men in the same trades appear to be doing broadly similar work, and to have similar patterns on health at the first follow-up, there are some significant differences in the types of employment and variety of tasks. The very detailed information collected will allow more precise estimates of exposures to be correlated with health outcomes at the end of the follow-up period. PMID- 29471428 TI - Cognitive behavioural therapy for fear of falling and balance among older people: a systematic review and meta-analysis. AB - Background: fear of falling is prevalent among older people and associated with various health outcomes. A growing number of studies have examined the effects of interventions designed to reduce the fear of falling and improve balance among older people, yet our current understanding is restricted to physiological interventions. Psychological interventions such as cognitive behavioural therapy (CBT) have not been reviewed and meta-analysed. Objective: to perform a systematic review and meta-analysis evaluating the effects of CBT on reducing fear of falling and enhancing balance in community-dwelling older people. Method: randomised controlled trials (RCTs) addressing fear of falling and balance were identified through searches of six electronic databases, concurrent registered clinical trials, forward citation and reference lists of three previous systematic reviews. Results: a total of six trials involving 1,626 participants were identified. Four studies used group-based interventions and two adopted individual intervention. Intervention period ranged from 4 to 20 weeks, and the number and duration of face-to-face contact varied. Core components of the CBT intervention included cognitive restructuring, personal goal setting and promotion of physical activities. The risk of bias was low across the included studies. Our analysis suggests that CBT interventions have significant immediate and retention effects up to 12 months on reducing fear of falling, and 6 months post-intervention effect on enhancing balance. Conclusions: CBT appears to be effective in reducing fear of falling and improving balance among older people. Future researches to investigate the use of CBT on reducing fear of falling and improving balance are warranted. PMID- 29471429 TI - Comparison of 3 methods for estimating enteric methane and carbon dioxide emission in nonlactating cows. AB - Among techniques for estimating enteric methane (CH4) emission by ruminants, open circuit respiration chambers (OC), the use of a gas tracer (SF6), and the GreenFeed (GF) device are the most commonly used. In this study, we compared these techniques in 8 dry cows receiving a diet made of 70% hay and 30% concentrates given in limited and constant amounts, in a 15-wk experiment. Two periods in free stalls for SF6 and GF and in chambers for OC were used; in addition, SF6 was determined in chambers for 1 period. Methane emission (g/d) and CH4 yield (g/kg DMI) were higher (P < 0.0001) for OC than for SF6 and GF (367, 310, and 319 g/d for OC, SF6, and GF, respectively). The difference between OC and GF was related to a difference in post-prandial rate of gas emission. The between-animal coefficient of variation of CH4 emission was higher for SF6 than for OC and GF (20.8, 13.5, and 12.0% on average, respectively). Correlation coefficients between OC and SF6 were high and significant for CH4 emission and CH4 yield (r = 0.782 and r = 0.717, respectively; P < 0.05), but not significant between OC and GF, or between SF6 and GF. Correlation coefficients were highly significant for SF6 determined either in free stalls or in chambers (r = 0.908 and 0.903 for CH4 in g/d and g/kg DMI, respectively; P < 0.01). Carbon dioxide (CO2) emission and CO2 yield were similar for GF and OC (10,003 and 9,887 g/d, 752 and 746 g/kg DMI, respectively); CO2 data obtained with SF6 were lower (7,718 g/d and 606 g/kg DMI; P < 0.0001), but this technique is not relevant for CO2 emission determination. Correlation coefficients between OC and GF were not significant for CO2 emission and CO2 yield. This set of results shows that differences between methods are minor for average values, but that individual correlations may limit their interchangeability for determining gas emissions of individual animals. This study also shows the reliability of GF on-farm determination of CH4 and CO2 emissions for groups of animals. PMID- 29471430 TI - GWAS identifies two novel colorectal cancer loci at 16q24.1 and 20q13.12. AB - Colorectal cancer (CRC) is the fourth leading cause of cancer mortality worldwide. Genome-wide association studies (GWAS) identified more than 50 CRC loci. However, most of the previous studies were conducted in European population, and host genetic factors among Japanese population are largely remained to be identified. To identify novel loci in the Japanese population, here, we performed a large-scale GWAS using 6692 cases and 27 178 controls followed by a replication analysis using more than 11 000 case-control samples. We found the significant association of 10 loci (P < 5 * 10-8), including 2 novel loci on 16q24.1 (IRF8-FOXF1, rs847208, P = 3.15 * 10-9 and odds ratio = 1.107 with 95% confidence interval (CI) of 1.071-1.145) and 20q13.12 (TOX2, rs6065668, P = 4.47 * 10-11 and odds ratio = 0.897 with 95% CI of 0.868-0.926). Moreover, 35 previously reported single nucleotide polymorphisms (SNPs) in 24 regions were validated in the Japanese population (P < 0.05) with the same risk allele as in the previous studies. SNP rs6065668 was significantly associated with TOX2 expression in the sigmoid colon. In addition, nucleotide substitutions in the regulatory region of TOX2 were predicted to alter the binding of several transcription factors, including KLF5. Our findings elucidate the important role of genetic variations in the development of CRC in the Japanese population. PMID- 29471431 TI - Making Waves: New Developments in Toxicology With the Zebrafish. AB - The laboratory zebrafish (Danio rerio) is now an accepted model in toxicologic research. The zebrafish model fills a niche between in vitro models and mammalian biomedical models. The developmental characteristics of the small fish are strategically being used by scientists to study topics ranging from high throughput toxicity screens to toxicity in multi- and transgenerational studies. High-throughput technology has increased the utility of zebrafish embryonic toxicity assays in screening of chemicals and drugs for toxicity or effect. Additionally, advances in behavioral characterization and experimental methodology allow for observation of recognizable phenotypic changes after xenobiotic exposure. Future directions in zebrafish research are predicted to take advantage of CRISPR-Cas9 genome editing methods in creating models of disease and interrogating mechanisms of action with fluorescent reporters or tagged proteins. Zebrafish can also model developmental origins of health and disease and multi- and transgenerational toxicity. The zebrafish has many advantages as a toxicologic model and new methodologies and areas of study continue to expand the usefulness and application of the zebrafish. PMID- 29471432 TI - Effectiveness of 7- and 13-Valent Pneumococcal Conjugate Vaccines in a Schedule Without a Booster Dose: A 10-Year Observational Study. AB - Background: Unique among high-income countries, Australia has used a 3 + 0 schedule (3 primary doses, no booster) for infant pneumococcal conjugate vaccine (PCV) since January 2005, initially 7 valent (PCV7) then 13 valent (PCV13) from July 2011. We measured vaccine effectiveness (VE) of both PCVs against invasive pneumococcal disease (IPD) using 2 methods. Methods: Cases were IPD notifications to the national surveillance system of children eligible for respective PCVs. For case-control method, up to 10 age-matched controls were derived from the Australian Childhood Immunisation Register. For indirect cohort method, controls were IPD cases due to serotypes not in PCVs. VE was calculated as (1 - odds ratio [OR]) * 100 by logistic regression. VE waning was estimated as odds of vaccine type (VT) IPD in consecutive 12-month periods post-dose 3. Results: Between 2005 and 2014, there were 1209 and 308 IPD cases in PCV7-eligible and PCV13-eligible cohorts, respectively. Both methods gave comparable VE estimates. In infants, VE for 3 doses against VT IPD was 92.9% (95% confidence interval [CI], 27.7% to 99.3%) for PCV7 and 86.5% (95% CI, 11.7% to 97.9%) for PCV13. From 12 months post dose 3, the odds of VT IPD by 24-36 months increased significantly for PCV7 (5.6, 95% CI, 1.2-25.4) and PCV13 (5.9, 95% CI, 1.0-35.2). Conclusions: For both PCVs in a 3 + 0 schedule, despite similar VE, progressive increase in breakthrough cases only occurred post-PCV13. This supports the importance of a booster dose of PCV13 in the second year of life to maintain protection. PMID- 29471433 TI - Reply to Godbole et al. PMID- 29471434 TI - Disease Definition for Schizophrenia by Functional Connectivity Using Radiomics Strategy. AB - Specific biomarker reflecting neurobiological substrates of schizophrenia (SZ) is required for its diagnosis and treatment selection of SZ. Evidence from neuroimaging has implicated disrupted functional connectivity in the pathophysiology. We aimed to develop and validate a method of disease definition for SZ by resting-state functional connectivity using radiomics strategy. This study included 2 data sets collected with different scanners. A total of 108 first-episode SZ patients and 121 healthy controls (HCs) participated in the current study, among which 80% patients and HCs (n = 183) and 20% (n = 46) were selected for training and testing in intra-data set validation and 1 of the 2 data sets was selected for training and the other for testing in inter-data set validation, respectively. Functional connectivity was calculated for both groups, features were selected by Least Absolute Shrinkage and Selection Operator (LASSO) method, and the clinical utility of its features and the generalizability of effects across samples were assessed using machine learning by training and validating multivariate classifiers in the independent samples. We found that the accuracy of intra-data set training was 87.09% for diagnosing SZ patients by applying functional connectivity features, with a validation in the independent replication data set (accuracy = 82.61%). The inter-data set validation further confirmed the disease definition by functional connectivity features (accuracy = 83.15% for training and 80.07% for testing). Our findings demonstrate a valid radiomics approach by functional connectivity to diagnose SZ, which is helpful to facilitate objective SZ individualized diagnosis using quantitative and specific functional connectivity biomarker. PMID- 29471435 TI - Immune Infiltration in Invasive Lobular Breast Cancer. AB - Background: Invasive lobular breast cancer (ILC) is the second most common histological subtype of breast cancer after invasive ductal cancer (IDC). Here, we aimed at evaluating the prevalence, levels, and composition of tumor infiltrating lymphocytes (TILs) and their association with clinico-pathological and outcome variables in ILC, and to compare them with IDC. Methods: We considered two patient series with TIL data: a multicentric retrospective series (n = 614) and the BIG 02-98 study (n = 149 ILC and 807 IDC). We compared immune subsets identified by immuno-histochemistry in the ILC (n = 159) and IDC (n = 468) patients from the Nottingham series, as well as the CIBERSORT immune profiling of the ILC (n = 98) and IDC (n = 388) METABRIC and The Cancer Genome Atlas patients. All ILC/IDC comparisons were done in estrogen receptor (ER) positive/human epidermal growth factor receptor 2 (HER2)-negative tumors. All statistical tests were two-sided. Results: TIL levels were statistically significantly lower in ILC compared with IDC (fold-change = 0.79, 95% confidence interval = 0.70 to 0.88, P < .001). In ILC, high TIL levels were associated with young age, lymph node involvement, and high proliferative tumors. In the univariate analysis, high TIL levels were associated with worse prognosis in the retrospective and BIG 02-98 lobular series, although they did not reach statistical significance in the latter. The Nottingham series revealed that the levels of intratumoral but not total CD8+ were statistically significantly lower in ILC compared with IDC. Comparison of the CIBERSORT profiles highlighted statistically significant differences in terms of immune composition. Conclusions: This study shows differences between the immune infiltrates of ER positive/HER2-negative ILC and IDC in terms of prevalence, levels, localization, composition, and clinical associations. PMID- 29471438 TI - Development of a health assessment instrument for people with intellectual disabilities: a Delphi study. AB - Background: People with intellectual disabilities (IDs) experience health inequalities. Applying health assessments is one way of diminishing these inequalities. A health assessment instrument can support general practitioners (GPs) in providing better medical care to people with ID. Objectives: The aim of this study was to determine which items should be part of a health assessment instrument for people with ID to be used in primary care. Methods: This Delphi consensus study was conducted among 24 GP experts and 21 ID physicians. We performed three anonymous sequential online questionnaire rounds. We started with 82 'general' items and 14 items concerning physical and additional examinations derived from the international literature and a focus group study among Dutch GPs. We definitely included items if more than 75% of the GP experts agreed on their inclusion. Results: The participation rate in all rounds was above 88%. The expert groups proposed 10 new items. Consensus was reached on 64 'general' items related to highly prevalent diseases, public health and health promotion. Consensus was also reached on 18 physical and additional examination items. Conclusions: For the first time, experts in a Delphi study were able to arrive at a selection of items for a health assessment instrument for people with ID. The overall agreement among the GPs and ID physicians was good. Because the experts prefer that patients complete the health assessment questionnaire at home, questions that cover these items must be formulated clearly. PMID- 29471436 TI - Antiandrogen Treatment Ameliorates Reproductive and Metabolic Phenotypes in the Letrozole-Induced Mouse Model of PCOS. AB - Polycystic ovary syndrome (PCOS), the most common endocrinopathy in women of reproductive age, is characterized by hyperandrogenism, anovulation, and polycystic ovaries. Although its etiology is unknown, excess androgens are thought to be a critical factor driving the pathology of PCOS. We previously demonstrated that continuous exposure to the aromatase inhibitor letrozole (LET) in mice produces many hallmarks of PCOS, including elevated testosterone (T) and luteinizing hormone, anovulation, and obesity. In the current study, we sought to determine whether androgen receptor (AR) actions are responsible for any of the phenotypes observed in LET mice. C57BL/6 female mice were subcutaneously implanted with LET or placebo control and subsequently treated with the nonsteroidal AR antagonist flutamide or vehicle control. Flutamide treatment in LET females reversed elevated T levels and restored ovarian expression of Cyp17a1 (critical for androgen synthesis) to normal levels. Pituitary expression of Lhb was decreased in LET females that received flutamide treatment, with no changes in expression of Fshb or Gnrhr. Flutamide treatment also restored estrous cycling and reduced the number of ovarian cyst-like follicles in LET females. Furthermore, body weight and adipocyte size were decreased in flutamide-treated LET females. Altogether, our findings provide strong evidence that AR signaling is responsible for many key reproductive and metabolic PCOS phenotypes and further establish the LET mouse model as an important tool for the study of androgen excess. PMID- 29471439 TI - Robot-assisted ligation of bronchial artery could be an alternative to embolization. AB - A 37-year-old patient presented with a self-limiting episode of moderate haemoptysis. Contrast-enhanced chest computed tomography showed a tortuous and dilated right bronchial artery arising from the descending aorta at the level of T6. Therapeutic angiography was attempted, but in the presence of spinal artery arising from the bronchial artery in question, selective embolization was contraindicated due to risk of spinal cord ischaemia. After a multidisciplinary meeting, it was decided to attempt surgery to ligate this pathological artery. We performed minimally invasive robot-assisted ligation of this pathological artery. The postoperative course was uneventful with good clinical and radiological outcome at 3-month follow-up. A minimally invasive approach provides a real alternative to embolization and could be a therapeutic option. PMID- 29471437 TI - Cerebellar BDNF Promotes Exploration and Seeking for Novelty. AB - Background: Approach system considered a motivational system that activates reward-seeking behavior is associated with exploration/impulsivity, whereas avoidance system considered an attentional system that promotes inhibition of appetitive responses is associated with active overt withdrawal. Approach and avoidance dispositions are modulated by distinct neurochemical profiles and synaptic patterns. However, the precise working of neurons and trafficking of molecules in the brain activity predisposing to approach and avoidance are yet unclear. Methods: In 3 phenotypes of inbred mice, avoiding, balancing, and approaching mice, selected by using the Approach/Avoidance Y-maze, we analyzed endogenous brain levels of brain derived neurotrophic factor, one of the main secretory proteins with pleiotropic action. To verify the effects of the acute increase of brain derived neurotrophic factor, balancing and avoiding mice were bilaterally brain derived neurotrophic factor-infused in the cortical cerebellar regions. Results: Approaching animals showed high levels of explorative behavior and response to novelty and exhibited higher brain derived neurotrophic factor levels in the cerebellar structures in comparison to the other 2 phenotypes of mice. Interestingly, brain derived neurotrophic factor-infused balancing and avoiding mice significantly increased their explorative behavior and response to novelty. Conclusions: Cerebellar brain derived neurotrophic factor may play a role in explorative and novelty-seeking responses that sustain the approach predisposition.

AB - Study Objectives: Adaptive servo-ventilation (ASV) devices provide anticyclic pressure support for the treatment of central and/or complex sleep apnea, including heart failure patients. Variability in responses in the clinic and negative clinical trials motivated assessment of standard and novel signal biomarkers for ASV efficacy. Methods: Multiple clinical databases were queried to assess potential signal biomarkers of ASV effectiveness, including the following: (1) attended laboratory adaptive ventilation titrations: 108, of which 66 had mainstream ETCO2 measurements; (2) AirView data in 98 participants, (3) complete data, from diagnostic polysomnogram (PSG) through review and prospective analysis of on-therapy data using SleepyHead freeware in 44 participants; and (4) hemodynamic data in the form of beat-to-beat blood pressure during ASV titration, using a Finometer in five participants. Results: Signal biomarkers of reduced ASV efficacy were noted as follows: (1) an arousal index which markedly exceeded the respiratory event index during positive pressure titration; (2) persistent pressure cycling during long-term ASV therapy, visible in online review systems or reviewing data using freeware; (3) the ASV-associated pressure cycling induced arousals, sleep fragmentation, and blood pressure surges; and (4) elevated ratios of 95th percentile to median tidal volume, minute ventilation, and respiratory rate were associated with pressure cycling. High intraclass coefficients (>0.8) for machine apnea-hypopnea index and other extractable metrics were consistent with stability of patterns over multiple nights of use. Global clinical outcomes correlated negatively with pressure cycling. Conclusions: Potential polysomnographic- and device-related signal biomarkers of ASV efficacy are described and may allow improved estimation of therapeutic effectiveness of adaptive ventilation. PMID- 29471443 TI - Immunomodulatory potential of dietary soybean-derived isoflavones and saponins in pigs. AB - In this review, the potential for use of soy-derived bioactive compounds as immunomodulatory feed additives in pigs is discussed. Soy is a major component of the modern U.S. swine diet in today's commercial industry, providing the bulk of dietary AA necessary for growth and production. However, soy use has generally been limited in early growth phases, during which the risks of immunological insult and disease are among the highest. Improvements of soybean processing and development of soy protein products with little to no antinutritional factors have made soy more appropriate for use in young pigs but additional processing may affect bioactive compound levels in the feed. The bioactive compounds of interest for this review are soy isoflavones and soy saponins. Soy isoflavones are flavonoid compounds with a range of biological activity including moderate estrogenic effects at low biological concentrations. Although estrogenic effects are of more interest in human medical research, isoflavones are also known for their anti-inflammatory, antioxidative properties at cellular levels, engaging several receptors and pathways including inhibition of NF-kappaB activation and inducible-nitric oxide synthase enzymes, thereby ascribing antiviral properties. Saponins, amphipathic glycoside compounds, also engage anti-inflammatory pathways, though their biological activity in pigs has not been well investigated and seem to mainly be observed on the mucous membrane in the gastrointestinal tract. Regarding use as an immunomodulatory feed additive, supplemental soy isoflavones have been shown to improve immunological status of pigs and produce mild improvements of growth performance under certain disease challenges including porcine reproductive and respiratory syndrome virus. Although more in vivo research in pigs is needed to fully understand biological activity of these compounds in the live animal, soy-derived bioactive compounds show great potential as a health promoting feed additive for the modern swine industry. PMID- 29471444 TI - Relation of Sex Hormone Levels With Prevalent and 10-Year Change in Aortic Distensibility Assessed by MRI: The Multi-Ethnic Study of Atherosclerosis. AB - BACKGROUND: Women experience a steeper decline in aortic elasticity related to aging compared to men. We examined whether sex hormone levels were associated with ascending aortic distensibility (AAD) in the Multi-Ethnic Study of Atherosclerosis. METHODS: We studied 1,345 postmenopausal women and 1,532 men aged 45-84 years, who had serum sex hormone levels, AAD measured by phase contrast cardiac magnetic resonance imaging, and ejection fraction>50% at baseline. Among these participants, 457 women and 548 men returned for follow-up magnetic resonance imaging 10-years later. Stratified by sex, and using mixed effects linear regression methods, we examined associations of sex hormones (as tertiles) with baseline and annual change in log-transformed AAD (mm Hg-110-3), adjusting for demographics, body size, lifestyle factors, mean arterial pressure, heart rate, hypertensive medication use (and in women, for hormone therapy use and years since menopause). RESULTS: The mean (SD) age was 65 (9) for women and 62 (10) years for men. AAD was lower in women than men (P < 0.001). In adjusted cross-sectional analysis, the highest tertile of free testosterone (compared to lowest) in women was significantly associated with lower AAD [-0.10 (-0.19, 0.01)] and the highest tertile of estradiol in men was associated with greater AAD [0.12 (0.04, 0.20)]. There were no associations of sex hormones with change in AAD over 10 years, albeit in a smaller sample size. CONCLUSIONS: Lower free testosterone in women and higher estradiol in men were associated with greater aortic distensibility at baseline, but not longitudinally. Sex hormone levels may account for differences in AAD between women and men. PMID- 29471445 TI - Does Soil Treated with Conidial Formulations of Trichoderma spp. Attract or Repel Subterranean Termites? AB - Previous studies showed that many wood-rotting fungi were attractive to termites; however, little attention has been paid to the relationship between termites and soil fungus. In the present study, different designs of two-choice tests were conducted to investigate the behaviors of two subterranean termites, Coptotermes formosanus Shiraki (wood-feeding lower termites) and Odontotermes formosanus (Shiraki) (fungus-growing higher termites), in response to soil (or sand) treated with the commercial conidial formulations of Trichoderma harzianum Rifai (BioWorks) and Trichoderma viride Pers. ex Fries (Shuiguxin). The short-term (1 d) choice tests showed no significant difference in termite aggregation (C. formosanus and O. formosanus) between treated and untreated soil, regardless of Trichoderma species and concentrations. However, in the long-term choice tests, C. formosanus consumed significantly more wood in the chambers containing soil treated with the conidial formulation of T. viride (1 * 108 conidia/g) than that containing untreated soil. The tunneling choice tests showed that sand treated with T. viride (1 * 106 or 1 * 108 conidia/g) or T. harzianum (1 * 106 conidia/g) significantly increased the tunneling activities of C. formosanus. However, sand treated with T. viride (1 * 106 or 1 * 108 conidia/g) had a repellent effect on O. formosanus. Our study showed that the two subterranean termites behaved differently when responding to the conidial formulations of Trichoderma. PMID- 29471447 TI - Corrigendum.

PMID- 29471449 TI - Obesity associated advanced glycation end products within the human uterine cavity adversely impact endometrial function and embryo implantation competence. AB - STUDY QUESTION: Do obese levels of advanced glycation end products (AGEs) within the uterine cavity detrimentally alter tissue function in embryo implantation and placental development? SUMMARY ANSWER: Obese levels of AGEs activate inflammatory signaling (p65 NFkappaB) within endometrial epithelial cells and alter their function, cause endoplasmic reticulum (ER) stress in endometrial stromal cells and impair decidualization, compromise implantation of blastocyst mimics and inhibit trophoblast invasion. WHAT IS KNOWN ALREADY: Obese women experience a higher incidence of infertility, recurrent miscarriage and pregnancy complications compared with lean women. Oocyte donation cycles suggest a detrimental uterine environment plays a role in these outcomes. STUDY DESIGN, SIZE, DURATION: Uterine lavage and tissues from lean (BMI 19.5-24.9, n = 17) and obese (BMI > 30, n = 16) women examined. Cell culture experiments utilizing human endometrial epithelial, trophectoderm and trophoblast cell lines and primary human stromal cells used to examine the functional impact of obese levels of AGEs. PARTICIPANTS/MATERIALS, SETTING, METHODS: Levels of AGEs examined within uterine lavage assessed by ELISA to determine differences between lean and obese women. Expression and localization of AGEs, receptor for AGEs (RAGE) and NFkappaB within endometrial tissues obtained from lean and obese women determined by immunohistochemistry. Endometrial epithelial cells (ECC-1), primary human stromal cells and trophoblast cells (HTR8-SVneo) treated with lean (2000 nmol/mol lysine) or obese (8000 nmol/mol lysine) uterine levels of AGEs and p65 NFkappaB (western immunoblot), real-time adhesion, proliferation migration and invasion (xCelligence real-time cell function analysis), decidualization (cell morphology and prolactin release), ER stress (western immunoblot for p-PERK) determined. Co cultures of endometrial epithelial cells and blastocyst mimics (trophectoderm spheroids) similarly treated with lean or obese uterine levels of AGEs to determine their impact on embryo implantation. MAIN RESULTS AND THE ROLE OF CHANCE: AGEs were significantly elevated (P = 0.004) within the obese (6503.59 MUmol/mol lysine) versus lean (2165.88 MUmol/mol lysine) uterine cavity (uterine lavage) with increased immunostaining for AGEs, RAGE and NFkB within obese endometrial tissues during the proliferative phase of the menstrual cycle. Obese uterine levels of AGEs inhibited adhesion and proliferation of endometrial epithelial (ECC-1) cells compared to treatment with lean uterine levels of AGEs. Obese uterine AGE levels impacted primary human endometrial stromal cell decidualization and activated ER stress within these cells. Obese uterine levels of AGEs also inhibited trophectodermal spheroid adhesion to hormonally primed endometrial epithelial cells and trophoblast cell line HTR8/SV-neo invasion. LARGE SCALE DATA: N/A. LIMITATIONS REASONS FOR CAUTION: Mechanistic studies are performed in vitro and may not completely recapitulate cell function in vivo. WIDER IMPLICATIONS OF THE FINDINGS: These data corroborate clinical data suggesting the presence of an altered uterine environment in obese women and demonstrate that elevated uterine levels of AGEs within these women may detrimentally impact endometrial function, embryo implantation and placental development. Uterine AGE assessment in infertility work up may prove useful in determining underlying causes of infertility. AGEs can be targeted pharmacologically and such treatments may prove effective in improving reproductive complications experience by obese women.

PMID- 29471450 TI - Stage-Dependent Expression of Deltamethrin Toxicity and Resistance in Triatoma infestans (Hemiptera: Reduviidae) From Argentina. AB - Triatoma infestans Klug (Hemiptera: Reduviidae) is the main vector of Chagas disease in Latin America. This insect has been controlled with pyrethroids since the 1980s, although the emergence of resistance to deltamethrin has decreased control success in some areas of the Gran Chaco ecoregion. The response of T. infestans to deltamethrin was evaluated per developmental stage. In addition, we evaluated the possible stage-dependent expression of deltamethrin resistance. The bioassays were conducted by topical application of the insecticide in acetone. The drop size, age at the time of exposure, and mortality measuring time were standardized per stage. The lethal dose of deltamethrin moderately increased with the developmental stage. The resistance to deltamethrin was expressed in every instar, and was the highest in the fourth- and fifth-instar nymphs. While increasing, weight plays a relevant role in lethal dose stage dependency, a number of contributing factors such as degradative metabolism are probably involved in the variability of insecticide effect and resistance described for different T. infestans developmental stages. Possible explanations for these differences and their implications on resistance management and chemical control are discussed. PMID- 29471451 TI - Genomic Evidence of Widespread Admixture from Polar Bears into Brown Bears during the Last Ice Age. AB - Recent genomic analyses have provided substantial evidence for past periods of gene flow from polar bears (Ursus maritimus) into Alaskan brown bears (Ursus arctos), with some analyses suggesting a link between climate change and genomic introgression. However, because it has mainly been possible to sample bears from the present day, the timing, frequency, and evolutionary significance of this admixture remains unknown. Here, we analyze genomic DNA from three additional and geographically distinct brown bear populations, including two that lived temporally close to the peak of the last ice age. We find evidence of admixture in all three populations, suggesting that admixture between these species has been common in their recent evolutionary history. In addition, analyses of ten fossil bears from the now-extinct Irish population indicate that admixture peaked during the last ice age, whereas brown bear and polar bear ranges overlapped. Following this peak, the proportion of polar bear ancestry in Irish brown bears declined rapidly until their extinction. Our results support a model in which ice age climate change created geographically widespread conditions conducive to admixture between polar bears and brown bears, as is again occurring today. We postulate that this model will be informative for many admixing species pairs impacted by climate change. Our results highlight the power of paleogenomics to reveal patterns of evolutionary change that are otherwise masked in contemporary data. PMID- 29471452 TI - Protecting the Community Through Child Vaccination. AB - The direct impact of vaccines on children is well described, but the major public health impact of indirect protection provided to the community by vaccines is underappreciated. Community protection occurs when vaccinated persons block the chain of transmission, protecting undervaccinated or unvaccinated susceptible community members by preventing exposure and limiting the spread of the pathogen through the community. Substantial declines in disease incidence have occurred shortly after implementing new childhood vaccines, including declines among vaccine-ineligible children, adolescents, and adults. Protection of susceptible community members depends on maintaining high vaccination rates. Improved recognition of community protection will strengthen childhood vaccination strategies that will protect our communities into the future. PMID- 29471453 TI - Modified Minimally Invasive Transforaminal Lumbar Interbody Fusion Technique Can Potentially Improve Safety of Interbody Graft Placement. AB - BACKGROUND: Minimally invasive transforaminal lumbar interbody fusion (MITLIF) is a well-described procedure with excellent reported outcomes. A modification of interbody graft placement can potentially improve the ease and safety of this procedure. OBJECTIVE: To describe a modification of the MITLIF graft placement and retrospectively review our experience including intraoperative and postoperative complications. METHODS: Single surgeon, single institution, retrospective analysis of consecutive patients who underwent a modified MITLIF technique between November 2011 and December 2013. Hospital records including operative notes and discharge summaries were reviewed for patient demographics, surgical parameters including operative time and estimated blood loss, intraoperative complications including durotomy/cerebrospinal fluid leak, and postoperative outcomes including time before ambulation and length of stay were all reviewed and analyzed. RESULTS: Eighty-three consecutive MITLIF patients; 71 underwent 1-level fusion and 12 had multilevel fusions. Average operative time for single level was 181 min; multilevel was 323 min. Average estimated blood loss was 140 mL. Time before ambulation was <1 d, average length of stay was 1.6 d. There were a total of 4 complications in this series (4.8%). There was zero incidence of durotomy or cerebrospinal fluid leak. CONCLUSION: This modified MITLIF technique of maintaining the medial facet prior to discectomy and interbody graft placement can offer the minimally invasive spine surgeons increased assurance while placing the graft and potentially enhance the overall safety and efficacy of this approach. Surgeons utilizing this approach will have little difficulty utilizing this slight modification. PMID- 29471454 TI - The Impact of Using Different Reference Populations on Measurement of Breast Cancer-Related Cognitive Impairment Rates. AB - Objective: To evaluate how use of different reference populations affects estimates of breast cancer-related cognitive impairment rates. Methods: Patients aged >=60 years with stage 0-3 breast cancer (n = 371) and matched non-cancer controls (n = 370) completed 13 neuropsychological tests prior to systemic therapy or at enrollment (controls). The tests captured three domains: attention, processing speed and executive function; learning and memory; and visual-spatial function. Domain-specific impairment was defined as having one test score 2 SD below or two or more test scores 1.5 SD below the reference population means. Different reference populations were used to define impairment: published normative data, study-specific controls, age and education-stratified controls, and age and education-adjusted controls. The associations between the resultant impairment rates and breast cancer (vs. control) were evaluated using chi-square tests and logistic regression models. Cohen's kappa coefficients were used to evaluate agreement of impairment rates between study-specific control performance and the other reference population groups. Results: The patients and controls were aged 68.0 (SD 6.0) and 67.9 (SD 7.0) years, respectively. The association of breast cancer-control status with impairment did not differ based on reference group. Cognitive impairment based on published normative data yielded less agreement on impairment rates (kappa = 0.22-0.89) than study-specific age and education-stratified control performance (kappa = 0.62-1.00). Conclusion: The choice of reference populations did not affect conclusions about the association of cognition with breast cancer. However, while study-specific reference populations provided greater internal consistency in defining cognitive impairment, benchmarking against published normative data will enhance the ability to compare results across studies. PMID- 29471455 TI - Chemical composition, energy, and amino acid digestibility in 7 cottonseed co products fed to growing pigs. AB - The objective of this study was to determine the chemical composition, DE and ME contents, and apparent ileal digestibility (AID) and standardized ileal digestibility (SID) of AA in 7 cottonseed co-products fed to growing pigs. The 7 cottonseed co-products were: cottonseed meals (solvent extracted) with CP level of 46%, 50%, and 55% (46CSM, 50CSM, and 55CSM), cottonseed protein with CP level of 50% and 55% (50CSP and 55CSP), fermented cottonseed meal (CSMF), and expelled cottonseed meal (CSME). The DE and ME contents of the 7 test ingredients were measured using 48 crossbreed barrows (BW: 44.1 +/- 4.2 kg) and 8 diets (including a corn-soybean meal basal diet) in a completely randomized design. The AID and SID of AA of the 7 test ingredients were determined using 7 crossbreed barrows (initial BW: 67.4 +/- 8.5 kg) in a 6 * 8 Youden square design with 6 periods and 8 diets (including one N-free diet). The DE and ME values of the 7 cottonseed co products varied from 12.72 to 15.63 MJ/kg and 12.24 to 14.83 MJ/kg, respectively. Among the 7 cottonseed co-products, 55CSP and CSME had the greatest (P < 0.05) ME and DE values compared to the other cottonseed co-products. In addition, 55CSP had the greatest (P < 0.05) AID and SID of all the AA tested except for Gly and Pro. In contrast, 46CSM or 55CSM had the lowest (P < 0.05) AID and SID of all the AA tested except for Gly and Pro. The 55CSP also had the greatest (P < 0.05) concentrations of standardized ileal digestible CP and all the AA tested except for Gly and Pro. In conclusion, the chemical composition, energy, and AA digestibility of cottonseed co-products with different processing techniques varied widely. Based on the energy and AA digestibility, cottonseed protein with CP level of 55% is a better dietary ingredient for growing pigs compared with the other cottonseed co-products.

AB - Background: A variety of different types of exercise are promoted to improve muscle strength and physical performance in older people. Objective: We aimed to determine the relative effects of resistance training, endurance training and whole-body vibration on lean body mass, muscle strength and physical performance in older people. Design: A systematic review and network meta-analysis. Subjects: Adults aged 60 and over. Methods: Evidence from randomised controlled trials of resistance training, endurance training and whole-body vibration were combined. The effects of exercise interventions on lean body mass, muscle strength and physical performance were evaluated by conducting a network meta-analysis to compare multiple interventions and usual care. Risk of bias of included studies was assessed using the Cochrane Collaboration's tool. A meta-regression was performed to assess potential effect modifiers. Results: Data were obtained from 30 trials involving 1,405 participants (age range: 60-92 years). No significant differences were found between the effects of exercise or usual care on lean body mass. Resistance training (minimum 6 weeks duration) achieved greater muscle strength improvement than did usual care (12.8 kg; 95% confidence interval [CI]: 8.5-17.0 kg). Resistance training and whole-body vibration were associated with greater physical performance improvement compared with usual care (2.6 times greater [95% CI: 1.3-3.9] and 2.1 times greater [95% CI: 0.5-3.7], respectively). Conclusions: Resistance training is the most effect intervention to improve muscle strength and physical performance in older people. Our findings also suggest that whole-body vibration is beneficial for physical performance. However, none of the three exercise interventions examined had a significant effect on lean body mass. PMID- 29471458 TI - Pro: The rationale for dietary therapy for patients with advanced chronic kidney disease. AB - Dietary treatment offers many benefits to patients with advanced chronic kidney disease (CKD) who are approaching the need for renal replacement therapy. A large number of these benefits are independent of whether diets slow the rate of progression of CKD. These diets are low in protein and many minerals, and provide adequate energy for the CKD patient. The diets can reduce accumulation of potentially toxic metabolic products derived from protein and amino acid degradation, maintain a healthier balance of body water, sodium, potassium, phosphorus, calcium and other minerals, and prevent or improve protein-energy wasting. Such diets may enable patients to safely delay the onset of chronic dialysis therapy or kidney transplantation. Dietary therapy may also augment the effectiveness of infrequent or incremental dialysis by maintaining healthier metabolic and clinical status and may enable some end-stage renal disease patients to avoid the need for temporary placement of hemodialysis catheters while their arterial venous fistulae or grafts mature. The anxiety that many advanced CKD patients commonly experience with regard to starting dialysis may incentivize them to accept and adhere to dietary therapy. PMID- 29471457 TI - Improving Anatomic Pathology in Sub-Saharan Africa to Support Cancer Care. AB - Objectives: Cancer care requires both accurate pathologic diagnosis as well as pathologic cancer staging. We evaluated three approaches to training pathologists in sub-Saharan Africa to perform pathologic cancer staging of breast, cervix, prostate, and colorectal cancers. Methods: One of three training methods was used at each workshop: didactic, case-based testing (CBT), or a blended approach. The project involved 52 participants from 16 pathology departments in 11 countries in East, Central, and Southern Africa. Evaluation of each method included pre- and postworkshop knowledge assessments, online pre- and postworkshop surveys of practice changes at the individual and institutional levels, and selected site visits. Results: While CBT resulted in the highest overall average postassessment individual scores, both CBT and blended approaches resulted in 19% increases in average scores from pre- to postworkshop assessments. Institutions that participated in the blended workshop had increased changes in practice as indicated by the institutional survey. Conclusions: Both CBT and a blended approach are effective methods for training pathologists in pathologic cancer staging. Both are superior to traditional lectures alone. PMID- 29471459 TI - Descriptive texture analyses of broiler breast fillets with the wooden breast condition stored at 4 degrees C and -20 degrees C. AB - The objective of this study was to evaluate the effects of the wooden breast (WB) condition on the texture of cooked broiler breast fillets (Pectoralis major) after fresh and frozen storage. Texture characteristics of normal (NORM) and severe WB fillets were studied by both sensory descriptive analyses and Warner Bratzler shear force. Broiler breast fillets were collected over 3 separate trial days from a commercial deboning line at 3 h postmortem, classified according to the wooden breast condition, and then stored at either 4 degrees C or -20 degrees C prior to cooking and texture evaluation. Fillets were cooked to an endpoint temperature of 76 degrees C and then evaluated by an 8-member trained sensory panel for springiness, cohesiveness, hardness, juiciness, cohesiveness of mass, bolus size, wetness of mass, fibrous texture, rate of breakdown, and chewiness. The fillets with the WB condition showed higher cook loss than those with NORM condition regardless of storage temperature. The mean value of shear force of WB fillets was lower than NORM fillets when cooked after 4 degrees C storage. Sensory evaluation showed that WB fillets were higher in springiness and cohesiveness than NORM fillets and that the sensory attributes springiness, hardness and fibrousness were perceived differently between ventral and dorsal sections of cooked WB fillets. This work indicates that human perception of cooked WB meat has texture irregularities. The cooked breast meat with the WB condition is perceived with more springiness and cohesiveness than that with no WB condition. PMID- 29471460 TI - Coaching primary care clinics for HPV vaccination quality improvement: Comparing in-person and webinar implementation. AB - State health departments commonly use quality improvement coaching as an implementation strategy for improving low human papillomavirus (HPV) vaccination coverage, but such coaching can be resource intensive. To explore opportunities for improving efficiency, we compared in-person and webinar delivery of coaching sessions on implementation outcomes, including reach, acceptability, and delivery cost. In 2015, we randomly assigned 148 high-volume primary care clinics in Illinois, Michigan, and Washington State to receive either in-person or webinar coaching. Coaching sessions lasted about 1 hr and used our Immunization Report Card to facilitate assessment and feedback. Clinics served over 213,000 patients ages 11-17. We used provider surveys and delivery cost assessment to collect implementation data. This report is focused exclusively on the implementation aspects of the intervention. More providers attended in-person than webinar coaching sessions (mean 9 vs. 5 providers per clinic, respectively, p = .004). More providers shared the Immunization Report Card at clinic staff meetings in the in-person than webinar arm (49% vs. 20%; p = .029). In both arms, providers' belief that their clinics' HPV vaccination coverage was too low increased, as did their self-efficacy to help their clinics improve (p < .05). Providers rated coaching sessions in the two arms equally highly on acceptability. Delivery cost per clinic was $733 for in-person coaching versus $461 for webinar coaching. In person and webinar coaching were well received and yielded improvements in provider beliefs and self-efficacy regarding HPV vaccine quality improvement. In summary, in-person coaching cost more than webinar coaching per clinic reached, but reached more providers. Further implementation research is needed to understand how and for whom webinar coaching may be appropriate. PMID- 29471461 TI - Gendered Pathways to Burnout: Results from the SALVEO Study. AB - Aim: Burnout is a pervasive mental health problem in the workforce, with mounting evidence suggesting ties with occupational and safety outcomes such as work injuries, critical events and musculoskeletal disorders. While environmental [work and non-work, work-to-family conflict (WFC)] and individual (personality) pathways to burnout are well documented, little is known about how gender comes to influence such associative patterns. The aim of the study consisted in examining gendered pathways to burnout. Methods: Data were derived from the SALVEO study, a cross-sectional study of 2026 workers from 63 workplaces from the province of Quebec (Canada). Data were analyzed using multilevel path analysis. Results: Direct effects of gendered pathways were evidenced for work (e.g. decision latitude) and non-work (e.g. child-related strains) environmental pathways, as well as for individual pathways (i.e. internal locus of control). Indirect effects of gendered pathways were also evidenced, with women reporting higher levels of burnout compared to men due to lower levels of decision latitude and of self-esteem, as well as higher levels of WFC. Women also reported lower burnout levels through investing more time into domestic tasks, which could represent a recovery strategy to highly demanding work. WFC further mediated the associations between working hours and burnout, as well as the between irregular work schedules and burnout. These result suggest than men distinctively reported higher levels of burnout due to the specific nature of their work contract negatively impacting on WFC, and incidentally, on their mental health. Conclusion: Study results supported our hypotheses positing that gender distinctively shapes environmental and individual pathways to burnout. OHS prevention efforts striving for better mental health outcomes in the workforce could relevantly be informed by a gendered approach to burnout.

PMID- 29471463 TI - Metapragmatic Explicitation and Social Attribution in Social Communication Disorder and Developmental Language Disorder: A Comparative Study. AB - Purpose: The purposes of this study are to investigate metapragmatic (MP) ability in 6-11-year-old children with social communication disorder (SCD), developmental language disorder (DLD), and typical language development and to explore factors associated with MP explicitation and social understanding (SU). Method: In this cross-sectional study, all participants (N = 82) completed an experimental task, the Assessment of Metapragmatics (Collins et al., 2014), in which pragmatic errors are identified in filmed interactions. Responses were scored for complexity/type of explicitation (MP score) and attribution of social characteristics to the films' characters (SU score). Results: Groups with SCD and DLD had significantly lower MP scores and less sophisticated explicitation than the group with typical language development. After controlling for language and age, the group with SCD had significantly lower SU scores than the group with DLD. Significant correlations were found between MP scores and age/language ability but not with pragmatic impairment. Conclusions: Children with SCD or DLD performed poorly on an MP task compared with children who are typically developing but do not differ from each other in ability to reflect verbally on pragmatic features in interactions. MP ability appears to be closely related to structural language ability. The limited ability of children with SCD to attribute social/psychological states to interlocutors may indicate additional social attribution limitations. PMID- 29471464 TI - Poor Immunogenicity, Not Vaccine Strain Egg Adaptation, May Explain the Low H3N2 Influenza Vaccine Effectiveness in 2012-2013. AB - Background: Influenza vaccination aims to prevent infection by influenza virus and reduce associated morbidity and mortality; however, vaccine effectiveness (VE) can be modest, especially for subtype A(H3N2). Low VE has been attributed to mismatches between the vaccine and circulating influenza strains and to the vaccine's elicitation of protective immunity in only a subset of the population. The low H3N2 VE in the 2012-2013 season was attributed to egg-adaptive mutations that created antigenic mismatch between the actual vaccine strain (IVR-165) and both the intended vaccine strain (A/Victoria/361/2011) and the predominant circulating strains (clades 3C.2 and 3C.3). Methods: We investigated the basis of low VE in 2012-2013 by determining whether vaccinated and unvaccinated individuals were infected by different viral strains and by assessing the serologic responses to IVR-165, A/Victoria/361/2011, and 3C.2 and 3C.3 strains in an adult cohort before and after vaccination. Results: We found no significant genetic differences between the strains that infected vaccinated and unvaccinated individuals. Vaccination increased titers to A/Victoria/361/2011 and 3C.2 and 3C.3 representative strains as much as to IVR-165. These results are consistent with the hypothesis that vaccination boosted cross-reactive immune responses instead of specific responses against unique vaccine epitopes. Only approximately one-third of the cohort achieved a >=4-fold increase in titer. Conclusions: In contrast to analyses based on ferret studies, low H3N2 VE in 2012-2013 in adults does not appear to be due to egg adaptation of the vaccine strain. Instead, low VE might have been caused by low vaccine immunogenicity in a subset of the population. PMID- 29471466 TI - Changes in Metabolites Present in Lung-Lining Fluid Following Exposure of Humans to Ozone. AB - Controlled human exposure to the oxidant air pollutant ozone causes decrements in lung function and increased inflammation as evidenced by neutrophil influx into the lung and increased levels of proinflammatory cytokines in the airways. Here we describe a targeted metabolomics evaluation of human bronchoalveolar lavage fluid (BALF) following controlled in vivo exposure to ozone to gain greater insight into its pulmonary effects. In a 2-arm cross-over study, each healthy adult human volunteer was randomly exposed to filtered air (FA) and to 0.3 ppm ozone for 2 h while undergoing intermittent exercise with a minimum of 4 weeks between exposures. Bronchoscopy was performed and BALF obtained at 1 (n = 9) or 24 (n = 23) h postexposure. Metabolites were detected using ultrahigh performance liquid chromatography-tandem mass spectroscopy. At 1-h postexposure, a total of 28 metabolites were differentially expressed (DE) (p < .05) following ozone exposure compared with FA-exposure. These changes were associated with increased glycolysis and antioxidant responses, suggesting rapid increased energy utilization as part of the cellular response to oxidative stress. At 24-h postexposure, 41 metabolites were DE. Many of the changes were in amino acids and linked with enhanced proteolysis. Changes associated with increased lipid membrane turnover were also observed. These later-stage changes were consistent with ongoing repair of airway tissues. There were 1.37 times as many metabolites were differentially expressed at 24 h compared with 1-h postexposure. The changes at 1 h reflect responses to oxidative stress while the changes at 24 h indicate a broader set of responses consistent with tissue repair. These results illustrate the ability of metabolomic analysis to identify mechanistic features of ozone toxicity and aspects of the subsequent tissue response. PMID- 29471465 TI - Effects of dietary energy level and intake of corn by-product-based diets on newly received growing cattle: antibody production, acute phase protein response, stress, and immunocompetency of healthy and morbid animals. AB - Effects of dietary energy level and intake of corn by-product-based diets on antibody production, acute phase protein response, stress, and immunocompetency of healthy and morbid newly received growing cattle were evaluated. Four dietary treatments were formulated to supply 0.99, 1.10, 1.21, and 1.32 Mcal NEg/ kg DM and were offered at 100%, 95%, 90%, and 85% of ad libitum based on 0.99/100 treatment intake, respectively. Thirty-two pens were utilized with approximately 12 animals/pen. Four animals from each pen (32/dietary treatment) were randomly selected and used to serve as a subset to monitor immune function and acute phase proteins following a split-plot design. In addition, two animals were randomly and independently selected from each pen (16/dietary treatment) and used to measure fecal cortisol metabolite. Additionally, animals removed from the pen one (M1), two (M2), or three (M3) times and classified as morbid were bled in conjunction with a healthy control (H) removed at the same time and the serum analyzed for the same parameters. A quadratic response to time (P < 0.01) was detected for haptoglobin concentrations and for antibody titers for bovine viral diarrhea type 1 (BVD-I) and infectious bovine rhinotracheitis (IBR; P < 0.01). Haptoglobin was lowest on arrival, highest on day 14, and similar to baseline levels by day 27. Titer levels for BVD-I and IBR were lowest on arrival, higher on day 14, and significantly higher on day 27. Titers for bovine viral diarrhea type 2 (BVD-II) responded linearly (P < 0.05) with lower levels on arrival and highest levels on day 27. Haptoglobin was elevated in morbid animals compared to healthy pen mates (P < 0.05). Titer levels for BVD-I and IBR were also higher in healthy animals compared to animals pulled for morbidity (P < 0.01). Fecal cortisol was higher on arrival than on day 14 (P < 0.05). Dietary treatment had no effect on any of the parameters investigated. In summary, high-energy receiving diets based on fermentable fiber from by-products can be fed to newly received growing cattle without negative effects on antibody production toward vaccines, inflammation, or overall stress. In addition, haptoglobin concentrations and titer levels for BVD-I and IBR viruses are higher in healthy animals compared to sick animals. PMID- 29471467 TI - Myeloperoxidase influences the complement regulatory activity of complement factor H. AB - Objective: The interaction between neutrophils and activation of alternative complement pathway plays a critical role in the pathogenesis of ANCA-associated vasculitis (AAV). MPO, which can be released from ANCA-stimulated neutrophils, was recently demonstrated to be capable of activating the alternative complement pathway. Here we aimed to investigate the interaction between MPO and factor H (FH), a key regulator of the alternative pathway, and its effect on the functional activities of FH. Methods: Detection of FH and MPO on neutrophil extracellular traps (NETs) induced by serum from AAV patients and in kidney biopsies of AAV patients was performed by immunostaining. In vitro binding between MPO and FH was examined by ELISA and surface plasmon resonance. The influence of MPO on the complement regulatory activity of FH was further assessed. Results: FH deposited and co-localized with MPO in NETs. In kidney biopsies from AAV patients, MPO was closely adjacent to FH in glomerular capillaries. We demonstrated that MPO binds to FH with an apparent nanomolar affinity and identified short consensus repeats 1-4 of FH as the major binding sites. In terms of functional analysis, MPO inhibited the interaction between FH and C3b and the decay-accelerating activity of FH. The fluid phase and surface cofactor activities of FH upon C3b inactivation were inhibited by MPO. Conclusion: Our findings indicate that MPO binds to FH and influences the complement regulatory activity of FH. MPO-FH interaction may participate in the pathogenesis of AAV by contributing to activation of the alternative complement pathway. PMID- 29471468 TI - Working conditions and stress in the English education system. AB - Background: The UK education sector has among the highest level of stress sickness absence of all occupations. However, investigations of psychosocial working conditions which contribute to stress, including behaviour of students and parents, has not been conducted. Aims: To investigate the psychosocial working conditions and prevalence of negative parental and student behaviour in a large sample of school teachers and college lecturers based in England. In addition, to assess the influence of working conditions, student behaviour and parental behaviour on perceived stress. Methods: A cross-sectional survey of teachers in England. Respondents completed the Management Standards Indicator Tool (MSIT), Perceived Stress Scale (PSS-4), Student Behaviour Scale and a two item measure of parental behaviour. Differences in these measures across different teaching roles were assessed using analysis of variance. Regression analyses were used to evaluate the association of MSIT, student and parental behaviour on PSS outcomes. Results: Compared to UK benchmark scoring, psychosocial working conditions were at a poor level, with primary teachers in particular exposed to negative parental behaviours, and secondary teachers to poor student behaviour. Demands were consistently associated with perceived stress outcomes across job roles, although management support and relationships with peers also played a part. Conclusions: Demands faced by teachers in England played an important part in the experience of stress. Interventions to reduce these demands, and the high frequencies of negative pupil and parental behaviours, should be considered. PMID- 29471470 TI - A Registry for Patients With Asplenia/Hyposplenism Reduces the Risk of Infections With Encapsulated Organisms. AB - Background: Overwhelming post-splenectomy infection (OPSI) is a serious complication of asplenia. Clinical guidelines recommend numerous measures to reduce the risk of OPSI, but awareness and adherence to preventative measures are generally poor. We aimed to determine whether a registry for asplenic/hyposplenic patients was associated with a reduction in the incidence of infection with encapsulated bacteria. Methods: We performed a retrospective cohort study of asplenic/hyposplenic patients in the state of Victoria, Australia, who registered with Spleen Australia from 2003 through 2014. Spleen Australia provides education, clinical guidance, and annual vaccination reminders to registrants and their healthcare providers. We compared the incidence of infection with Streptococcus pneumoniae, Haemophilus influenzae type B (Hib), and Neisseria meningitidis before and after registration. Registry data were linked with Victorian notifiable disease data on invasive pneumococcal disease (IPD), invasive meningococcal disease (IMD), and Hib between 2000 and 2014. Results: Twenty-seven cases of IPD and 1 of IMD occurred among 3221 registrants. No cases of Hib were reported. The rate of IPD/IMD was 150 per 100000 patient-years prior to registration and 36 per 100000 patient-years after registration; registration was associated with a 69% reduction in the risk of infection (incidence rate ratio, 0.31; 95% confidence interval, 0.12 to 0.83; P = .019). Based on the absolute reduction in incidence, we estimate that Spleen Australia prevents 5-6 invasive infections with encapsulated organisms annually among registrants. Conclusions: Systematic, long-term approaches to post-splenectomy care can significantly reduce the risk of infection with encapsulated organisms among individuals with asplenia/hyposplenism. PMID- 29471469 TI - Effect of lemon leaves on energy and C-N balances, methane emission, and milk performance in Murciano-Granadina dairy goats. AB - The objective of this experiment was to find out the effect of lemon leaves on energy and C-N balances, methane emission, and milk performance in dairy goats. Lemon leaves were used to replace alfalfa as forage in a diet for Murciano Granadina goats. Ten Murciano-Granadina dairy goats (44.1 +/- 4.47 kg of BW) in late lactation (185 +/- 7.2 d) were selected in a crossover design experiment, where each goat received 2 treatments in 2 periods. One group was fed a mixed ration with 450 g of pelleted alfalfa per kilogram of DM (ALF diet) and, the other group replaced alfalfa with 450 g of pelleted lemon leaves per kilogram DM (LEM diet). The concentrate was pelleted, being the same for the two groups (forage to concentrate ratio was 45/55). The goats were allocated to individual metabolism cages. After 14 d of adaptation, feed intake, total fecal and urine output, and milk yield were recorded daily over a 5-d period. Then, gas exchange measurements were recorded individually by an open-circuit indirect calorimetry system using a head box. Higher dietary lipids in LEM diet reduced DMI (200 g/d) and energy intake (251 kJ/kg of BW0.75), although no differences between treatments were observed for ME intake (998 kJ/kg of BW0.75, on average) and oxidation of nutrients (64% and 25% for carbohydrates and fat oxidation, respectively, on heat production from oxidation basis). Greater (P < 0.05) milk fat values for C18:2n6t and CLA 9c11t + 9t11c were found in LEM compared with ALF diet. Goats fed LEM diet produced significantly fewer CH4 emissions than ALF diet (18%). Likewise, the use of lemon leaves as forage reduced the amount of CH4 in 2.7 g/kg of milk. Results suggest that lemon leaves are effective in reducing CH4 emission without detrimental effect on milk yield.

PMID- 29471473 TI - Bidirectional GPR119 Agonism Requires Peptide YY and Glucose for Activity in Mouse and Human Colon Mucosa. AB - The lipid sensor G protein-coupled receptor 119 (GPR119) is highly expressed by enteroendocrine L-cells and pancreatic beta-cells that release the hormones, peptide YY (PYY) and glucagonlike peptide 1, and insulin, respectively. Endogenous oleoylethanolamide (OEA) and the dietary metabolite, 2 monoacylglycerol (2-OG), can each activate GPR119. Here, we compared mucosal responses with selective, synthetic GPR119 agonists (AR440006 and AR231453) and the lipids, OEA, 2-OG, and N-oleoyldopamine (OLDA), monitoring epithelial ion transport as a readout for L-cell activity in native mouse and human gastrointestinal (GI) mucosae. We also assessed GPR119 modulation of colonic motility in wild-type (WT), GPR119-deficient (GPR119-/-), and PYY-deficient (PYY /-) mice. The water-soluble GPR119 agonist, AR440006 (that cannot traverse epithelial tight junctions), elicited responses, when added apically or basolaterally in mouse and human colonic mucosae. In both species, GPR119 responses were PYY, Y1 receptor mediated, and glucose dependent. AR440006 efficacy matched the GI distribution of L-cells in WT tissues but was absent from GPR119-/- tissue. OEA and 2-OG responses were significantly reduced in the GPR119 /- colon, but OLDA responses were unchanged. Alternative L-cell activation via free fatty acid receptors 1, 3, and 4 and the G protein-coupled bile acid receptor TGR5 or by the melanocortin 4 receptor, was unchanged in GPR119-/- tissues. The GPR119 agonist slowed transit in WT but not the PYY-/- colon in vitro. AR440006 (intraperitoneally) slowed WT colonic and upper-GI transit significantly in vivo. These data indicate that luminal or blood-borne GPR119 agonism can stimulate L-cell PYY release with paracrine consequences and slower motility. We suggest that this glucose-dependent L-cell response to a gut restricted GPR119 stimulus has potential therapeutic advantage in modulating insulinotropic signaling with reduced risk of hypoglycemia.

PMID- 29471475 TI - Assessing Viral Transfer During Doffing of Ebola-Level Personal Protective Equipment in a Biocontainment Unit. AB - Background: Personal protective equipment (PPE) protects healthcare workers (HCWs) caring for patients with Ebola virus disease (EVD), and PPE doffing is a critical point for preventing viral self-contamination. We assessed contamination of skin, gloves, and scrubs after doffing Ebola-level PPE contaminated with surrogate viruses: bacteriophages MS2 and Phi6. Methods: In a medical biocontainment unit, HCWs (n = 10) experienced in EVD care donned and doffed PPE following unit protocols that incorporate trained observer guidance and alcohol based hand rub (ABHR). A mixture of Phi6 (enveloped), MS2 (nonenveloped), and fluorescent marker was applied to 4 PPE sites, approximating body fluid viral load (Phi6, 105; MS2, 106). They performed a patient care task, then doffed. Inner gloves, face, hands, and scrubs were sampled for virus, as were environmental sites with visible fluorescent marker. Results: Among 10 HCWs there was no Phi6 transfer to inner gloves, hands, or face; 1 participant had Phi6 on scrubs at low levels (1.4 * 102). MS2 transfer (range, 101-106) was observed to scrubs (n = 2), hands (n = 1), and inner gloves (n = 7), where it was highest. Most (n = 8) had only 1 positive site. Environmental samples with visible fluorescent marker (n = 21) were negative. Conclusions: Among experienced HCWs, structured, observed doffing using ABHR protected against hand contamination with enveloped virus. Nonenveloped virus was infrequent on hands and scrubs but common on inner gloves, suggesting that inner gloves, but not necessarily ABHR, protect against hand contamination. Optimizing doffing protocols to protect against all types of viruses may require reinforcing careful handling of scrubs and good glove/hand hygiene with effective agents. PMID- 29471477 TI - Feasibility of smartphone application and social media intervention on breast cancer survivors' health outcomes. AB - Breast cancer survivors are at risk for poor health, with physical activity a possible treatment. Little research has examined how technology might promote breast cancer survivor physical activity or health. The aim of this study is to investigate the feasibility of employing a commercially available mobile health application- and social media-based health education intervention to improve breast cancer survivor physical activity or health.Ten breast cancer survivors (X age = 45.80 +/- 10.23 years; X weight = 79.51 +/- 20.85 kg) participated in this 10-week single-group pilot study from 2015 to 2016. Participants downloaded the MapMyFitness application, documented all physical activity with MapMyFitness, and were enrolled in a Social Cognitive Theory-based, Facebook-delivered health education intervention. Objectively measured physical activity, weight or body composition, cardiovascular fitness, psychosocial constructs, and quality of life indices were measured at baseline and 10 weeks. Intervention use and acceptability was evaluated during and following the intervention. Descriptive statistics were calculated for all study outcomes, with qualitative analyses performed regarding use and acceptability. At postintervention, average daily moderate-to-vigorous physical activity and steps increased by 2.6 min and 1,657, respectively, with notable decreases in weight (2.4 kg) and body fat percentage (2.3%). Physical activity-related social support and ability to engage in social roles or activity demonstrated the greatest improvements among all psychosocial and quality of life indices, respectively. Participants enjoyed the feedback and tracking features of MapMyFitness, with most finding the Facebook component helpful. All participants recommended the intervention for future use.Physical activity interventions combining commercially available mobile health applications and theoretically based social media-delivered health interventions may promote certain physiological, psychosocial, and quality of life outcomes among breast cancer survivors. Larger samples and randomized studies are warranted. PMID- 29471478 TI - Internet-Delivered Cognitive-Behavioral Therapy for Insomnia in Breast Cancer Survivors: A Randomized Controlled Trial. AB - Background: Insomnia is two to three times more prevalent in cancer survivors than in the general population, where it is estimated to be 10% to 20%. Cognitive behavioral therapy for insomnia (CBT-I) is the recommended treatment for chronic insomnia, but meeting survivor needs remains a challenge. Internet-delivered CBT I (iCBT-I) has been shown efficacious in otherwise healthy adults. We tested the efficacy of iCBT-I in breast cancer survivors with clinically significant sleep disturbance. Methods: Women from a national sample of Danish breast cancer survivors who experienced clinically significant sleep disturbance were randomly allocated to iCBT-I or waitlist control (55:45). The fully automated iCBT-I program consisted of six cores. Online measures of insomnia severity, sleep quality, and fatigue were collected at baseline, postintervention (nine weeks), and follow-up (15 weeks). Online sleep diaries were completed over two-week periods pre- and postintervention. Intention-to-treat analyses (time * group interactions) were conducted with mixed linear models and corrected for multiple outcomes. All statistical tests were two-sided. Results: A total of 255 women were randomly allocated to iCBT-I (n = 133) or waitlist control (n = 122). Statistically significant (P <= .02) time * group interactions were found for all sleep-related outcomes from pre- to postintervention. Effect sizes (Cohen's d) ranged from 0.33 (95% confidence interval [CI] = 0.06 to 0.61) for wake after sleep onset to 1.17 (95% CI = 0.87 to 1.47) for insomnia severity. Improvements were maintained for outcomes measured at follow-up (d = 0.66-1.10). Conclusions: iCBT-I appears to be effective in breast cancer survivors, with additional benefit in terms of reduced fatigue. This low-cost treatment could be incorporated in cancer rehabilitation programs.

AB - Honey bee, Apis mellifera (L.; Hymenoptera: Apidae), populations are in decline and their losses pose a serious threat for crop pollination and food production. The specific causes of these losses are believed to be multifactorial. Pesticides, parasites and pathogens, and nutritional deficiencies have been implicated in the losses due to their ability to exert energetic stress on bees. While our understanding of the role of these factors in honey bee colony losses has improved, there is still a lack of knowledge of how they impact the immune system of the honey bee. In this study, honey bee colonies were exposed to Fumagilin-B, Apistan (tau-fluvalinate), and chlorothalonil at field realistic levels. No significant effects of the antibiotic and two pesticides were observed on the levels of varroa mite, Nosema ceranae (Fries; Microsporidia: Nosematidae), black queen cell virus, deformed wing virus, or immunity as measured by phenoloxidase and glucose oxidase activity. Any effects on the parasites, pathogens, and immunity we observed appear to be due mainly to seasonal changes within the honey bee colonies. The results suggest that Fumagilin-B, Apistan, and chlorothalonil do not significantly impact the health of honey bee colonies, based on the factors analyzed and the concentration of chemicals tested. PMID- 29471480 TI - Family Medicine Clinic: a case study of a hospital-family medicine practice redesign to improve chronic disease care in the community in Singapore. AB - Background: Singapore's health care system is strained by the health care needs of a rapidly aging population. The unprecedented collaboration between a public hospital and a private family practice to set up the Family Medicine Clinic (FMC) to co-manage patients with chronic disease is an example of efforts to shift care to the community. Objective: To explore patients' initial experience of shared chronic disease care in a private family practice setting. Methods: In this exploratory case study, we surveyed 330 patients with stable chronic diseases and interviewed 10 complex care patients and their caregivers. Results: Most patients were willing to transfer their care from the hospital to a FMC and satisfied with the care received. Patients reported enhanced access at FMC and appreciated the improvement in care continuity and care coordination across settings. Patients with complex care needs felt engaged with their case manager even though they did not understand case management. Despite the favourable assessment of FMC, patients sought care from other health care providers and a third of patients would leave if the subsidy for their care at FMC was removed. Families and caregivers felt that their needs could be better addressed and that FMC could play a role. Conclusions: To ensure that patients' initial positive experience translates to a long-term relationship with FMC, providers should move beyond providing improved access to care. It is necessary to help patients understand the comparative advantage of community-based care and its contribution to long term health outcomes. Providers should also elicit patients' desires and expectations when designing future models of care. At a policy level, higher cost of private primary care should be addressed.

AB - We report the discovery of large numbers of Haemaphysalis longicornis Neumann (Ixodida: Ixodidae) infesting a sheep in Hunterdon County, New Jersey, United States. All life stages were found on the sheep, which had no history of travel outside the country. H. longicornis is native to East Asia, and there are invasive populations in Australia, New Zealand and several Pacific islands, where this tick is a major livestock pest. It is currently unknown whether the New Jersey collections represent a limited or established population, but because this species could present a significant threat to human and animal health in the United States, vigilance is encouraged. PMID- 29471481 TI - Bacterial-fungal interactions: ecology, mechanisms and challenges. AB - Fungi and bacteria are found living together in a wide variety of environments. Their interactions are significant drivers of many ecosystem functions and are important for the health of plants and animals. A large number of fungal and bacterial families engage in complex interactions that lead to critical behavioural shifts of the microorganisms ranging from mutualism to antagonism. The importance of bacterial-fungal interactions (BFI) in environmental science, medicine and biotechnology has led to the emergence of a dynamic and multidisciplinary research field that combines highly diverse approaches including molecular biology, genomics, geochemistry, chemical and microbial ecology, biophysics and ecological modelling. In this review, we discuss recent advances that underscore the roles of BFI across relevant habitats and ecosystems. A particular focus is placed on the understanding of BFI within complex microbial communities and in regard of the metaorganism concept. We also discuss recent discoveries that clarify the (molecular) mechanisms involved in bacterial-fungal relationships, and the contribution of new technologies to decipher generic principles of BFI in terms of physical associations and molecular dialogues. Finally, we discuss future directions for research in order to stimulate synergy within the BFI research area and to resolve outstanding questions. PMID- 29471483 TI - Transfer accuracy of two indirect bonding techniques-an in vitro study with 3D scanned models. AB - Background and objectives: Indirect bonding (IDB) proved to be an effective method for appropriate bracket positioning in patients. Different methods and materials are available for fabricating transfer trays. This in vitro study was designed to measure and compare the transfer accuracy of two common IDB methods. Materials and methods: Sixty stone models were fabricated and separated in two groups of 30 models each (15 working models, 15 patient models). After placing brackets on the working models, 30 IDB trays were made: 15 silicone (method I) and 15 double-vacuum forms (method II). With these trays, the brackets were transferred to the patient models. The bracket positions were scanned before and after the IDB procedure with an intraoral scanner. The linear and angular discrepancies were then determined digitally by measuring six different dimensions: occluso-cervical, mesio-distal, bucco-lingual, tip, rotation, and torque. Results: The silicone trays showed fewer transfer discrepancies, on average, in all measured dimensions. There were significant differences between the methods in the occluso-cervical (P < 0.001), mesio-distal (P = 0.001), and torque (P = 0.044) dimensions. With both methods, 100 per cent of the horizontal and transversal measurements of both methods were within the clinically acceptable range of 0.25 mm. With method I, 98.5 per cent of the vertical and 95.9 per cent of the angular measurements were within the range of 0.25 mm and 1 degrees , respectively. With method II, 94 per cent of the vertical and 84.8 per cent of the angular measurements were within the clinically acceptable range. Conclusions: Although both transfer methods showed a high precision, silicone trays scored better in terms of accuracy than double-vacuum forms. PMID- 29471484 TI - A study of the knowledge, attitudes and practices of Tibetan yak herders with respect to brucellosis. AB - Background: Little information is available regarding the knowledge, attitudes and practices (KAP) of the owners of yaks in Tibet with respect to brucellosis. Methods: This manuscript reports on the results of a cross-sectional survey using a structured questionnaire investigating the KAP of 317 yak herders from 34 villages in the three main yak-rearing counties of Maizhokunggar, Damxung and Yadong from April to August 2015. Results: Although 60.6% of the respondents had heard of brucellosis, there was an overall low level of knowledge about the disease. Herders did, however, adopt management/husbandry practices which would reduce transmission of the disease to humans and other animals. Multivariable logistic modelling showed that a better knowledge was predicted by age, production system adopted, education level and number of people in a household. Differences in attitudes and practices were predicted by education level, production system and household size. Conclusions: In order to increase the awareness of herders on brucellosis and to reduce the risk of infection in both humans and other animals, public health education campaigns should be developed and offered to livestock owners in Tibet. PMID- 29471485 TI - Trabecular bone score as an assessment tool to identify the risk of osteoporosis in axial spondyloarthritis: a case-control study. AB - Objectives: To compare the trabecular bone score (TBS) between patients with axial spondyloarthritis (axSpA) and matched normal controls and identify risk factors associated with a low TBS. Methods: TBS and BMD were assessed in the two groups (axSpA and control) using DXA. Osteoporosis risk factors and inflammatory markers were also assessed. Disease activity and radiographic progression in the sacroiliac joint and spine were evaluated in the axSpA group. Multivariate linear regression analysis was performed to identify risk factors associated with TBS. Results: In the axSpA group, 248 subjects were enrolled; an equal number of age- and sex-matched subjects comprised the control group. The mean TBS was 1.43 (0.08) and 1.38 (0.12) in the control and axSpA groups, respectively (P < 0.001); BMD at the lumbar spine did not differ between the two groups. The TBS was negatively correlated with ESR and CRP levels in the axSpA group only (P < 0.001 and P = 0.007, respectively). Syndesmophytes in the axSpA group was associated with lower TBS (P < 0.001) but higher lumbar BMD (P = 0.021) vs controls. In the multivariate analyses, ESR, CRP and spinal radiographic progression were significantly associated with TBS. Conclusion: TBS assessments revealed poor bone quality in patients with axSpA compared with the matched controls. In axSpA, systemic inflammatory markers were negatively correlated with TBS and spinal radiographic progression and inflammatory markers were independently correlated with low TBS. TBS may, therefore, be a useful clinical tool to identify the risk of osteoporosis in patients with axSpA. PMID- 29471486 TI - Selection of hyperproduction of AmpC and SME-1 in a carbapenem-resistant Serratia marcescens isolate during antibiotic therapy. AB - Objectives: Antibiotic selective pressure may result in changes to antimicrobial susceptibility throughout the course of infection, especially for organisms that harbour chromosomally encoded AmpC beta-lactamases, notably Enterobacter spp., in which hyperexpression of ampC may be induced following treatment with cephalosporins. In this study, we document a case of bacteraemia caused by a blaSME-1-harbouring Serratia marcescens that subsequently developed resistance to expanded-spectrum cephalosporins, piperacillin/tazobactam and fluoroquinolones, over the course of several months of treatment with piperacillin/tazobactam and ciprofloxacin. Methods: Susceptibility testing and WGS were performed on three S. marcescens isolates from the patient. beta-Lactamase activity in the presence or absence of induction by imipenem was measured by nitrocefin hydrolysis assays. Expression of ampC and blaSME-1 under the same conditions was determined by real time PCR. Results: WGS demonstrated accumulation of missense and nonsense mutations in ampD associated with stable derepression of AmpC. Gene expression and beta-lactamase activity of both AmpC and SME-1 were inducible in the initial susceptible isolate, but were constitutively high in the resistant isolate, in which total beta-lactamase activity was increased by 128-fold. Conclusions: Although development of such in vitro resistance due to selective pressure imposed by antibiotics is reportedly low in S. marcescens, our findings highlight the need to evaluate isolates on a regular basis during long-term antibiotic therapy. PMID- 29471487 TI - The Lesser Antillean Iguana (Iguana delicatissima) on St. Eustatius: Genetically Depauperate and Threatened by Ongoing Hybridization. AB - The Lesser Antillean Iguana (Iguana delicatissima) is an endangered species threatened by habitat loss and hybridization with non-native Green Iguanas (Iguana iguana). Iguana delicatissima has been extirpated on several islands, and the Green Iguana has invaded most islands with extant populations. Information is essential to protect this species from extinction. We collected data on 293 iguanas including 17 juveniles from St. Eustasius, one of the few remaining I. delicatissima strongholds. Genetic data were leveraged to test for hybridization presence with the Green Iguana using both mitochondrial and nuclear genes, including 16 microsatellite loci. The microsatellites were also analyzed to estimate genetic diversity, population structure, and effective population size. Using molecular and morphological data, we identified 286 I. delicatissima individuals captured during our first fieldwork effort, and 7 non-native iguanas captured during a second effort, showing hybridization occurs within this population. Comparing homologous microsatellites used in studies on Dominica and Chancel, the I. delicatissima population on St. Eustatius has extremely low genetic diversity (HO = 0.051; HE = 0.057), suggesting this population is genetically depauperate. Furthermore, there is significant evidence for inbreeding (FIS = 0.12) and weak spatial genetic structure (FST = 0.021, P = 0.002) within this population. Besides immediate threats including hybridization, this population's low genetic diversity, presence of physiological abnormalities and low recruitment could indicate presence of inbreeding depression that threatens its long-term survival. We conclude there is a continued region-wide threat to I. delicatissima and highlight the need for immediate conservation action to stop the continuing spread of Green Iguanas and to eliminate hybridization from St. Eustatius. PMID- 29471488 TI - Morphological responses of plant roots to mechanical stress. AB - Background: Roots are continuously exposed to mechanical pressure and this often results in their morphological modification. Most obvious are changes in the overall form of the root system as well as in the shapes of particular roots. These changes are often accompanied by modifications of the cell pattern and cell morphology. Scope: This review focuses on the morphological responses of roots to mechanical stress. Results of early and recent experiments in which roots have been exposed to mechanical pressure are assembled, analysed and discussed. Research applying different experimental sets, obstacles, media of various compactness and structure are reviewed. An effect of the combination of mechanical stresses with other abiotic stresses on roots, and results of estimating the force exerted by the roots are briefly discussed. Possible consequences of the cell pattern rearrangements are considered. Conclusions: Several modifications in root morphology are commonly reported: (1) decreased root size, (2) radial swelling accompanied by increased radial dimension of the cortex cell layers and (3) enhanced cap cell sloughing. Nevertheless, because of differences between species and individual plants, a universal scenario for root morphological changes resulting from externally applied pressures is not possible. Thus, knowledge of the root response to mechanical impedance remains incomplete. Studies on the mechanical properties of the root as well as on possible modifications in cell wall structure and composition as the elements responsible for the mechanical properties of the plant tissue are required to understand the response of root tissue as a biomaterial. PMID- 29471489 TI - The H-subunit of the restriction endonuclease CglI contains a prototype DEAD-Z1 helicase-like motor. AB - CglI is a restriction endonuclease from Corynebacterium glutamicum that forms a complex between: two R-subunits that have site specific-recognition and nuclease domains; and two H-subunits, with Superfamily 2 helicase-like DEAD domains, and uncharacterized Z1 and C-terminal domains. ATP hydrolysis by the H-subunits catalyses dsDNA translocation that is necessary for long-range movement along DNA that activates nuclease activity. Here, we provide biochemical and molecular modelling evidence that shows that Z1 has a fold distantly-related to RecA, and that the DEAD-Z1 domains together form an ATP binding interface and are the prototype of a previously undescribed monomeric helicase-like motor. The DEAD-Z1 motor has unusual Walker A and Motif VI sequences those nonetheless have their expected functions. Additionally, it contains DEAD-Z1-specific features: an H/H motif and a loop (aa 163-aa 172), that both play a role in the coupling of ATP hydrolysis to DNA cleavage. We also solved the crystal structure of the C terminal domain which has a unique fold, and demonstrate that the Z1-C domains are the principal DNA binding interface of the H-subunit. Finally, we use small angle X-ray scattering to provide a model for how the H-subunit domains are arranged in a dimeric complex. PMID- 29471490 TI - Pharmacologic assessment of bovine ruminal and mesenteric vascular serotonin receptor populations. AB - Prior work using a contractility bioassay determined that the serotonin (5-HT) receptor subtype 5-HT2A is present in bovine lateral saphenous veins and plays a role in ergot alkaloid (EA)-induced vascular contraction in steers grazing endophyte-infected (Epichloe coenophiala) tall fescue (Lolium arundinaceum). Ergot alkaloids have also been shown to be vasoactive in bovine gut vasculature. To determine what 5-HT receptors are involved in vasoconstriction of gut vasculature, contractility of ruminal and mesenteric arteries and veins collected from cattle was evaluated in the presence of agonists selective for 5-HT1B (CP 93129), 5-HT1D (L-694, 247), 5-HT2A (TCB-2), 5-HT2B (BW 723C86), 5-HT4 (BIMU-8), and 5-HT7 (LP 44) receptors. Segments of ruminal and mesenteric veins and arteries were collected and suspended in a multimyograph containing continuously oxygenated Krebs-Henseleit buffer. Blood vessels were exposed to increasing concentrations of 5-HT agonists every 15 min and contractile response data were normalized as a percentage of the maximum contractile response induced by 120 mM KCl. Analysis of variance was evaluated using mixed models procedure of SAS for effects of agonist concentration for each vessel type. Receptor agonists for 5 HT2B, 5-HT1D, and 5-HT7 did not induce a contractile response for ruminal or mesenteric vasculature (P > 0.05). However, when exposed to agonists for 5-HT2B or 5-HT1D, mesenteric veins relaxed below zero (P < 0.05). Exposure of all 4 blood vessel types to 5-HT2A agonist induced contractile responses (P < 0.05). The findings of this study indicate that 5-HT1D and 5-HT2B are present in mesenteric veins and may play a role in vasorelaxation. Further, 5-HT2A is present in ruminal and mesenteric vasculature, plays a role in vasoconstriction of these vessels, and could be influenced by EA exposure as has been demonstrated in peripheral blood vessels. PMID- 29471491 TI - Farming characteristics and self-reported health outcomes of Irish farmers. AB - Background: Irish farmers represent a 'high-risk' group for non-communicable diseases, which, arguably, pose a greater occupational health challenge for farmers. To date, there has been little exploration of the farming characteristics associated with farmers' poor health outcomes. Aims: To examine the relationship between farming and male farmers' self-reported health outcomes and to compare the study findings to national health studies to explore which factors specifically are associated with Irish farmers' poorer health outcomes relative to the general population. Methods: This cross-sectional survey research used self-reported quantitative data on the health outcomes and health behaviours of male farmers from the South-East of Ireland. Data were entered into SPSS and descriptive and binary regression techniques were used for data analysis. Results: There were 314 participants (99% response rate). Age, full-time farming and dairy farming significantly impacted self-reported health outcomes and health behaviours. There was a high prevalence of self-reported arthritis compared with the national average of Irish males. 'Younger' farmers (<45 years) were more likely to engage in harmful health behaviours such as smoking and 'binge drinking' one or more times per week. Conclusions: This study identified self reported patterns of risky lifestyle behaviours among particular subgroups of Irish farmers for whom targeted health interventions are warranted. Interventions are particularly important for younger farmers who may see themselves as invincible and impregnable to ill-health.

AB - BACKGROUND: It is not uncommon for women with endometriosis to be advised that becoming pregnant might be a useful strategy to manage their symptoms and reduce disease progression. Consequently, many women diagnosed with endometriosis and motivated to become pregnant, may also have expectations regarding improvement of symptoms and the disease. However, study results on the effect of pregnancy on endometriosis are controversial and pregnancy in women with endometriosis is not always associated with improved symptoms. Moreover, there is increasing evidence that endometriosis may interfere with a successful pregnancy outcome. OBJECTIVE AND RATIONALE: The objective was to evaluate the evidence on whether pregnancy and lactation has a beneficiary effect on growth characteristics and symptoms of endometriosis diagnosed prior to pregnancy. SEARCH METHODS: A search for articles containing keywords related to pregnancy and endometriosis was performed via PubMed. Manuscripts dealing with a potential effect of pregnancy on endometriosis were systematically reviewed. We included English, French and German language publications on human studies from 1966 to May 2017. Bibliographies of these manuscripts were searched for further relevant literature. OUTCOMES: Five small observational studies were identified concerning the longitudinal development of endometriotic lesions during and after pregnancy, four of medium and one of low quality. Eleven publications reported measurements of endometriomas during pregnancy and the postpartum period (the five studies just mentioned and six case reports). Another 22 case reports/small case series (maximum of five cases), six studies on histology of endometriotic lesions in pregnancy, plus eight studies on the role of pregnancy in initial development and recurrence of endometriosis were included. Few studies of very limited quality are available to evaluate the effect of pregnancy and the postnatal period on the development of endometriosis. The development of endometriosis is variable and there is no evidence that pregnancy can be expected to generally reduce the size and number of endometriotic lesions. Growth and structural changes of lesions during pregnancy may occur with decidualization. Results on the association between pregnancy and symptoms of endometriosis are controversial and strongly biased. WIDER IMPLICATIONS: Available data on the development of endometriosis during and after pregnancy show fewer beneficial effects than previously reported. Therefore, women aiming for pregnancy on the background of endometriosis should not be told that pregnancy may be a strategy for managing symptoms and reducing progression of the disease. PMID- 29471494 TI - Morphological, Physiological, and Biochemical Responses of Two Tea Cultivars to Empoasca onukii (Hemiptera: Cicadellidae) Infestation. AB - The tea green leafhopper, Empoasca onukii Matsuda (Hemiptera: Cicadellidae), is an economically important pest of tea crops, Camellia sinensis (L.) O. Kuntze (Ericales: Theaceae), in China. The morphological, physiological, and biochemical changes of two tea cultivars, the normal green tea cultivar 'Fudingdabai' and the novel chlorophyll-deficient albino cultivar 'Huangjinya', infested by E. onukii were investigated to determine the tolerance of different tea cultivars to E. onukii attack. E.onukii infestation affected the growth of tea plants, and decreased the shoot length, leaf area, leaf thickness, and stem diameter. Also, E. onukii infestation lowered the thicknesses of upper epidermis, palisade tissue, and spongy tissue of leaves, and the parenchyma tissue thickness and pith diameter of stem internode. E.onukii infestation reduced the chlorophyll a, b and carotenoid contents within the leaves of 'Huangjinya,' which further influenced the photosynthetic rate. The maximum quantum yield and actual photochemical efficiency of photosystem II, and non-photochemical quenching in 'Huangjinya' were inhibited under E. onukii infestation. Peroxidase activity of E. onukii infested 'Huangjinya' increased more than superoxide dismutase and catalase. In addition, E. onukii feeding changed the contents of free amino acids, tea polyphenols, caffeine, and catechins in leaves of 'Huangjinya'. Overall, the light-induced albino cultivar 'Huangjinya' was susceptible to E. onukii while 'Fudingdabai' was resistant. PMID- 29471495 TI - Arginine methylation of the C-terminus RGG motif promotes TOP3B topoisomerase activity and stress granule localization. AB - DNA topoisomerase 3B (TOP3B) is unique among all mammalian topoisomerases for its dual activities that resolve both DNA and RNA topological entanglements to facilitate transcription and translation. However, the mechanism by which TOP3B activity is regulated is still elusive. Here, we have identified arginine methylation as an important post-translational modification (PTM) for TOP3B activity. Protein arginine methyltransferase (PRMT) 1, PRMT3 and PRMT6 all methylate TOP3B in vitro at its C-terminal arginine (R) and glycine (G)-rich motif. Site-directed mutagenesis analysis identified R833 and R835 as the major methylation sites. Using a methylation-specific antibody, we confirmed that TOP3B is methylated in cells and that mutation of R833 and R835 to lysine (K) significantly reduces TOP3B methylation. The methylation-deficient TOP3B (R833/835K) is less active in resolving negatively supercoiled DNA, which consequently lead to accumulation of co-transcriptionally formed R-loops in vitro and in cells. Additionally, the methylation-deficient TOP3B (R833/835K) shows reduced stress granule localization, indicating that methylation is critical for TOP3B function in translation regulation. Mechanistically, we found that R833/835 methylation is partially involved in the interaction of TOP3B with its auxiliary factor, the Tudor domain-containing protein 3 (TDRD3). Together, our findings provide the first evidence for the regulation of TOP3B activity by PTM. PMID- 29471496 TI - Should Acute Q-Fever Patients be Screened for Valvulopathy to Prevent Endocarditis? AB - Background: Echocardiographic screening of acute Q-fever patients and antibiotic prophylaxis for patients with cardiac valvulopathy is considered an important approach to prevent chronic Q-fever-related endocarditis. During a large Q-fever epidemic in the Netherlands, routine screening echocardiography was discontinued, raising controversy in the international literature. We followed a cohort of acute Q-fever patients to estimate the risk for developing chronic Q-fever, and we evaluated the impact of screening in patients who were not yet known to have a valvulopathy. Methods: The study population consisted of patients diagnosed with acute Q-fever in 2007 and 2008. We retrospectively reviewed all screening echocardiographs and checked for development of chronic Q-fever 8 years after the acute episode. Risks of developing chronic Q-fever in relation to the presence or absence of valvulopathy were analyzed with logistic regression. Results: The cohort included 509 patients, of whom 306 received echocardiographic screening. There was no significant difference (P-value = .22) in occurrence of chronic Q fever between patients with a newly detected valvulopathy (2/84, 2.4%) and those with no valvulopathy (12/202, 5.9%). Two patients with a newly detected valvulopathy, who did not receive antibiotic prophylaxis, developed chronic Q fever at a later stage. Conclusions: We found no difference in outcome between patients with and without a valvulopathy newly detected by echocardiographic screening. In retrospect, the 2 above-mentioned patients could have benefitted from antibiotic prophylaxis, but its omission must be weighed against the unnecessary large-scale and long-term use of antibiotics that would have resulted from universal echocardiographic screening. PMID- 29471497 TI - Increased NK Cell Function After Cessation of Long-Term Nucleos(t)ide Analogue Treatment in Chronic Hepatitis B Is Associated With Liver Damage and HBsAg Loss. AB - Background: Treatment with nucleos(t)ide analogues (NA) suppresses hepatitis B virus (HBV) DNA but rarely leads to functional cure of chronic hepatitis B (CHB). Following NA cessation, some hepatitis B e antigen (HBeAg)-negative CHB patients experience hepatitis B s antigen (HBsAg) loss. Cellular immune responses, including natural killer (NK) cell responses, explaining virological events following NA treatment cessation remain elusive. Methods: In a single-center prospective trial, 15 HBeAg-negative CHB patients on long-term NA treatment underwent structured NA cessation and were studied longitudinally. The NK cell compartment was assessed using high-dimensional flow cytometry and correlated with the clinical course. Results: Unsupervised stochastic neighbor embedding analysis revealed NA-treated CHB patients to have a significantly affected NK cell compartment compared to controls. Cessation of NA treatment resulted in minor phenotypic alterations, but it significantly augmented NK cell natural cytotoxicity responses in the CHB patients. This increased NK cell functionality correlated with alanine aminotransferase flares in the patients and was particularly enhanced in patients experiencing HBsAg seroclearance at long-term follow-up. Conclusions: Increased NK cell function is associated with active hepatitis and HBsAg seroclearance following structured NA cessation. This adds to our knowledge of the immunological events that develop following cessation of NA treatment in CHB. PMID- 29471498 TI - "It was the best worst day of my life": Narrative Content, Structure, and Process in Wisdom-Fostering Life Event Memories. AB - Objectives: The purpose of this study was to examine laypeople's subjective understanding of their own wisdom development. To do this, autobiographical memories of wisdom-fostering life events were examined for (a) life-event characteristics, and (b) self-reflective processes believed to support growth in wisdom through life experience. Methods: Midlife adults (N = 482) provided a written autobiographical memory of a wisdom-fostering life event. Memories were content analyzed by expert coders for life-event characteristics (i.e., fundamentality, emotional valence, cultural normativity, and specific event types) and self-reflective processes (i.e., narrative coherence, meaning-making, and personal growth). Participants also completed self-report and performance measures of wisdom. Results: Wisdom-fostering life events tended to be fundamental to life, culturally non-normative, and emotionally negative. Participants frequently reported developing wisdom from relationship events (e.g., interpersonal conflict, divorce) and life-threatening/mortality events (e.g., death, serious illness). Wisdom was positively associated with reconstructive (i.e., narrative coherence) and analytical (i.e., meaning-making, personal growth) components of self-reflection. Self-reflective processes varied as a function of life-event characteristics. Discussion: This study emphasizes the role of both persons and environments in the development of wisdom, and highlights the importance of self-reflection as a mechanism through which wisdom is constructed from life experience. PMID- 29471499 TI - Mineral content of eggs differs with hen strain, age, and rearing environment. AB - Egg nutrient quality is strongly influenced by hen diet but is also affected by rearing environment, hen strain, and hen age. The objective of the current study was to determine the effect of: 1) conventional battery cages, 2) enrichable cage systems, 3) enriched colony housing, 4) cage-free, and 5) free-range rearing systems on mineral concentrations of whole, dried egg (yolk and albumen combined) from TA Tetra White (TW) and Hy-Line Brown (HB) hens at 44, 68, and 88 wk of age. We hypothesized that mineral concentration of eggs would differ among rearing systems but not between strains or with hen age. Hens held in enriched colony housing systems produced eggs with 10% lower Mg and 11% lower Mn levels than conventional hens. Concentrations of Ca and Cu were higher (7 and 8%, respectively) in eggs from TW hens than from HB hens. Eggs from HB hens had 8% higher concentrations of Fe, 6% higher Mg and 5% higher Mn than TW hens. Mn was higher in eggs from 44-wk hens than from 68- or 88-wk hens (16 and 11%, respectively). Interaction effects between rearing environment and hen age were observed for K and Mn concentrations. Eggs from 68-wk hens in conventional rearing systems contained 14 to 21% more K than eggs from conventional hens at 44 and 88 wk and 14 to 18% more than eggs from 68-wk hens in other rearing systems. At 88 wk of age, hens in conventional rearing systems produced eggs with higher Mn concentration than hens in enrichable or enriched colony housing systems (22 and 23%, respectively). Interactions between rearing environment, hen strain, and hen age were observed for egg Zn levels among 44- and 68-wk hens but were not detectable among 88-wk hens regardless of rearing system or hen strain. Observed differences in egg mineral content in our study were small and are unlikely to have substantial impact on human nutrition. PMID- 29471500 TI - Molecular Identification of Leishmania spp. in Sand Flies (Diptera: Psychodidae: Phlebotominae) in the Lencois Maranhenses National Park, Brazil. AB - Sand flies are very common in the region of Lencois Maranhenses National Park, an important tourist attraction in Brazil. However, the role of some species and their relative importance locally in Leishmania Ross 1903 transmission is unclear. The objective of this study was to identify Leishmania infection in phlebotomine sand flies collected around the Lencois Maranhenses National Park, an important conservation area and popular international/national tourist destination with a high incidence of leishmaniasis. Sand flies were collected in peridomiciliary areas on the tourist route from September 2012 to August 2013. The captured females were subjected to molecular analyses for the detection of Leishmania DNA. Sand flies were infected with four Leishmania species: Leishmania (Viannia) braziliensis (Vianna, 1911) was found in Lutzomyia whitmani (Antunes and Coutinho, 1939) (2.1%) and Lutzomyia longipalpis (Lutz and Neiva, 1912) (1.7%); Leishmania (Leishmania) infantum (Nicole, 1908) infected Lutzomyia wellcomei (Fraiha, Shaw, and Lainson, 1971) (20%), Lutzomyia sordellii (Shannon and Del Ponte, 1927) (4.3%), Lu. longipalpis (3.7%), and Lu. whitmani (0.8%); Leishmania (Leishmania) amazonensis (Lainson & Shaw, 1972) was found in Lu. whitmani (0.58%), while Leishmania (Viannia) lainsoni infected Lutzomyia evandroi (Costa Lima and Antunes, 1936) (3.4%), Lu. longipalpis (1.06%), and Lu. whitmani (0.29%). The occurrence of these parasites requires control measures to reduce the incidence of cutaneous leishmaniasis and to contain a possible epidemic of visceral leishmaniasis, the most severe form of the disease. PMID- 29471501 TI - Contemporary Ecological Interactions Improve Models of Past Trait Evolution. AB - Despite the fact that natural selection underlies both traits and interactions, evolutionary models often neglect that ecological interactions may, and in many cases do, influence the evolution of traits. Herein, we explore the interdependence of ecological interactions and functional traits in the pollination associations of hawkmoths and flowering plants. Specifically, we develop an adaptation of the Ornstein-Uhlenbeck model of trait evolution that allows us to study the influence of plant corolla depth and observed hawkmoth plant interactions on the evolution of hawkmoth proboscis length. Across diverse modelling scenarios, we find that the inclusion of contemporary interactions can provide a better description of trait evolution than the null expectation. Moreover, we show that the pollination interactions provide more-likely models of hawkmoth trait evolution when interactions are considered at increasingly fine scale groups of hawkmoths. Finally, we demonstrate how the results of best-fit modeling approaches can implicitly support the association between interactions and trait evolution that our method explicitly examines. In showing that contemporary interactions can provide insight into the historical evolution of hawkmoth proboscis length, we demonstrate the clear utility of incorporating additional ecological information to models designed to study past trait evolution. PMID- 29471502 TI - Elevated G6PD expression contributes to migration and invasion of hepatocellular carcinoma cells by inducing epithelial-mesenchymal transition. AB - Altered metabolism is one of the hallmarks of cancer cells. Pentose phosphate pathway (PPP) is a fundamental component of cellular metabolism. Glucose-6 phosphate dehydrogenase (G6PD), the rate-limiting enzyme of the PPP, is elevated in many cancers and contributes to tumor growth by producing ribose-5-phosphate and NADPH through PPP. However, the role of G6PD in hepatocellular carcinoma (HCC) metastasis and the clinical significance of G6PD in HCC progression and prognosis have not been well determined. In this study, by investigating tissue samples from HCC patients and HCC cell lines, we found that elevated G6PD expression is significantly associated with HCC metastasis and poor prognosis of HCCs, and that knockdown of G6PD inhibits in vitro proliferation, migration and invasion of HCC cell lines. Further studies reveal that G6PD contributes to HCC migration and invasion of hepatocellular carcinoma cells by inducing epithelial mesenchymal transition through activation of signal transducer and activator of transcription 3 (STAT3) pathway. Our findings suggest that targeting G6PD could open up possibilities for metastasis intervention and improve the patients' outcomes for HCC. PMID- 29471503 TI - The role of the reprogramming method and pluripotency state in gamete differentiation from patient-specific human pluripotent stem cells. AB - The derivation of gametes from patient-specific pluripotent stem cells may provide new perspectives for genetic parenthood for patients currently facing sterility. We use current data to assess the gamete differentiation potential of patient-specific pluripotent stem cells and to determine which reprogramming strategy holds the greatest promise for future clinical applications. First, we compare the two best established somatic cell reprogramming strategies: the production of induced pluripotent stem cells (iPSC) and somatic cell nuclear transfer followed by embryonic stem cell derivation (SCNT-ESC). Recent reports have indicated that these stem cells, though displaying a similar pluripotency potential, show important differences at the epigenomic level, which may have repercussions on their applicability. By comparing data on the genetic and epigenetic stability of these cell types during derivation and in-vitro culture, we assess the reprogramming efficiency of both technologies and possible effects on the subsequent differentiation potential of these cells. Moreover, we discuss possible implications of mitochondrial heteroplasmy. We also address the ethical aspects of both cell types, as well as the safety considerations associated with clinical applications using these cells, e.g. the known genomic instability of human PSCs during long-term culture. Secondly, we discuss the role of the stem cell pluripotency state in germ cell differentiation. In mice, success in germ cell development from pluripotent stem cells could only be achieved when starting from a naive state of pluripotency. It remains to be investigated if the naive state is also crucial for germ cell differentiation in human cells and to what extent human naive pluripotency resembles the naive state in mouse. PMID- 29471504 TI - Anodyne by Design; Measuring the Prevalence of Esoteric Designer Opioids in Pain Management Patients. AB - The recent increase in illicit opioids sold on the black market, cut into heroin and masqueraded as prescription pills prompts a significant public health concern. Most designer opioids possess unknown potencies and unknown pharmacokinetics and their unregulated, variable dosages lead to rashes of overdoses. Additionally, many of the designer opioids, especially the fentanyl analogs are significantly more potent than heroin. High-profile cases involving overdoses of U-47700 and carfentanil have been reported in the media; however, the true prevalence of these and other designer opioids is unknown. Independent LC-MS-MS screen and confirmation methods have been developed and validated to identify and quantify fentanyl, and 18 designer opioids and their metabolites; methods were then exercised on urine specimens from contract pain management clients. Assuming patients in a pain management program may have a higher probability to seek out self-medication, samples from pain management patients were investigated for designer opioids. Similarly, pain management patients identified as using heroin may be more likely to experiment with or be accidentally exposed to designer opioids, specimens screening positive for the heroin metabolite 6-acetylmorphine were specifically chosen for designer opioid screening. Within this small group of pain management and heroin-positive samples, nine designer opioids were detected at a total prevalence of 25%. When screening random pain management samples not positive for heroin, a considerably lower percentage of samples (<1%) were identified as positive for designer opioids. Furanyl fentanyl, fluorobutyryl fentanyl and acetylfentanyl were the most prevalent designer opioids detected in both test groups. PMID- 29471505 TI - Involvement of cholinesterases in oxidative stress induced by chlorpyrifos in the brain of Japanese quail. AB - Chlorpyrifos is a widely used organophosphate pesticide (OP). In birds and mammals OP exhibits a toxic effect via inhibition of cholinesterases [acetylcholinesterase (AChE) and butyrylcholinesterase (BChE)] and through oxidative/nitrosative stress. In this study, the influence of chlorpyrifos on cholinesterase activity, parameters of oxidative stress [malondialdehyde (MDA); glutathione (GSH); superoxide dismutase (SOD); nitrite concentration (NO2-); hydrogen peroxide (H2O2)], and inflammatory parameter [activity of myeloperoxidase (MPO)] in the brain of Japanese quail (Coturnix japanica) was examined. The study was conducted on a total of 60 male Japanese quails (one control and 5 experimental groups, n = 10), 3 to 4 wk old. Quails were administered by gavage chlorpyrifos (CPF) for 7 consecutive da at doses of 0.375 mg/kg BW, 0.75 mg/kg BW, 1.5 mg/kg BW, 3 mg/kg BW, and 6 mg/kg BW. Our studies have shown that all doses of CPF significantly inhibited both cholinesterases in brain: AChE from 22.74 to 37.83% and BChE from 19.53 to 61.9%, and that inhibition was dose dependent. Also, CPF has led to an increase in the concentration of MDA, GSH, NO2-, and H2O2 and activity of SOD and MPO. Overall, these results support the hypothesis that CPF causes oxidative stress and inflammatory response. This research was carried out on quails because there is hardly any or not enough data about the neurotoxic effect of CPF and especially about its influence on oxidative stress in birds. This study is highly important because we are witnessing massive avian mortality in certain countries due to pesticides. PMID- 29471507 TI - Di(2-Ethylhexyl) Phthalate Exposure During Prenatal Development Causes Adverse Transgenerational Effects on Female Fertility in Mice. AB - Di(2-ethylhexyl) phthalate (DEHP) is a ubiquitous environmental toxicant and endocrine disrupting chemical, but little is known about its effects on female reproduction. Thus, we tested the hypothesis that prenatal exposure to DEHP accelerates the onset of puberty, disrupts estrous cyclicity, disrupts birth outcomes, and reduces fertility in the F1, F2, and F3 generations of female mice. Pregnant CD-1 mice were orally dosed with corn oil (vehicle control) or DEHP (20 and 200 ug/kg/day and 500 and 750 mg/kg/day) from gestation day 10.5 until birth. F1 females were mated with untreated males to obtain the F2 generation. F2 females were mated with untreated males to produce the F3 generation. In all generations, the onset of puberty, estrous cyclicity, select birth outcomes, and fertility-related indices were evaluated. In the F1 generation, prenatal DEHP exposure (200 ug/kg/day) accelerated the onset of puberty, it (200 ug and 500 mg/kg/day) disrupted estrous cyclicity, and it (20 and 200 ug/kg/day) decreased fertility-related indices. In the F2 generation, ancestral DEHP exposure (500 mg/kg/day) accelerated the onset of puberty, it (20 and 200 ug/kg/day) disrupted estrous cyclicity, it (20 ug and 500 mg/kg/day) increased litter size, and it (500 mg/kg/day) decreased fertility-related indices. In the F3 generation, ancestral DEHP exposure (20, 200 ug, and 500 mg/kg/day) accelerated the onset of puberty, it (20 ug/kg/day) disrupted estrous cyclicity, and it (750 mg/kg/day) decreased female pup anogenital index. Collectively, these data indicate that prenatal DEHP exposure causes female reproductive problems in a multigenerational and transgenerational manner. PMID- 29471508 TI - Protein hydrolysate from turkey meat and optimization of its antioxidant potential by response surface methodology. AB - The objective of this research was to optimize antioxidant potential of hydrolyzed protein using Flavourzyme assisted hydrolysis of turkey meat and compare the antioxidant activity of hydrolysates from turkey meat, chicken, and beef. Response surface methodology (RSM) was used to determine the optimal Flavourzyme hydrolysis conditions for preparation of hydrolysate from turkey meat, which were at a temperature of 50.09 degrees C, pH of 5.42, and processing time of 1.08 hours. For comparison, antioxidant activities of the hydrolysate from turkey meat, chicken, and beef under the optimum conditions were determined using reducing power, 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) radical cation, hydroxyl radical, and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activities. The antioxidant activity of turkey meat and chicken meat was significantly higher than that of beef (P < 0.05). Therefore Flavourzyme could be regarded as an effective hydrolytic enzyme for preparation of antioxidant hydrolysate from turkey meat, indicating the potential use of it as a functional food ingredient with shelf-life extension purposes. PMID- 29471506 TI - A translational silencing function of MCPIP1/Regnase-1 specified by the target site context. AB - The expression of proteins during inflammatory and immune reactions is coordinated by post-transcriptional mechanisms. A particularly strong suppression of protein expression is exerted by a conserved translational silencing element (TSE) identified in the 3' UTR of NFKBIZ mRNA, which is among the targets of the RNA-binding proteins Roquin-1/2 and MCPIP1/Regnase-1. We present evidence that in the context of the TSE MCPIP1, so far known for its endonuclease activity toward mRNAs specified by distinct stem-loop (SL) structures, also suppresses translation. Overexpression of MCPIP1 silenced translation in a TSE-dependent manner and reduced ribosome occupancy of the mRNA. Correspondingly, MCPIP1 depletion alleviated silencing and increased polysomal association of the mRNA. Translationally silenced NFKBIZ or reporter mRNAs were mostly capped, polyadenylated and ribosome associated. Furthermore, MCPIP1 silenced also cap independent, CrPV-IRES-dependent translation. This suggests that MCPIP1 suppresses a post-initiation step. The TSE is predicted to form five SL structures. SL4 and 5 resemble target structures reported for MCPIP1 and together were sufficient for MCPIP1 binding and mRNA destabilization. Translational silencing, however, required SL1-3 in addition. Thus the NFKBIZ TSE functions as an RNA element in which sequences adjacent to the site of interaction with MCPIP1 and dispensable for accelerated mRNA degradation extend the functional repertoire of MCPIP1 to translational silencing.

PMID- 29471510 TI - Moderator's view: Low-protein diet in chronic kidney disease: effectiveness, efficacy and precision nutritional treatments in nephrology. AB - Intention-to-treat and per-protocol analyses provide complementary information about the usefulness of therapies. While intention-to-treat analyses of trials that tested low-protein diets remain debated, per-protocol analyses of the same trials show that low protein intake actually reduces the risk of kidney failure. Per-protocol analyses are notoriously open to bias but intention-to-treat analyses are less immaculate than commonly realized because they critically depend on adherence to the treatment being tested and therefore may not be directly relevant for informing clinical decisions when different degrees of adherence to therapy occur. Over the last 20 years new statistical techniques censoring patients at the time when they become uncompliant and that adjust for confounding attributable to incomplete adherence, i.e. for prognostic factors that predict adherence to treatment, have been developed. These techniques can be usefully applied to reanalyse the Modification Diet in Renal Disease (MDRD) and other trials. Intensive surveillance of patients on a low-protein diet is fundamental for early detection of malnutrition. However, the resources demanded by such surveillance are likely superior to the actual dietitians workforce dedicated to follow-up of the chronic kidney disease (CKD) population. Surveillance efforts may perhaps be preferentially devoted to preselected patients, i.e. patients that maintain good compliance and an adequate metabolic and nutritional status, while patients who are resistant to educational efforts and show persisting uncompliance may be reallocated to a diet with a higher protein content, which poses a lower risk of malnutrition and other adverse health outcomes. PMID- 29471511 TI - Sexual Dimorphism in the Behavioral Responses and the Immunoendocrine Status in d Galactose-Induced Aging. AB - For almost 20 years, chronic systemic d-galactose, a monosaccharide abundantly present in milk products, fruits, and vegetables, has been used as a tool to achieve models of accelerated aging. Its neurotoxicity, induced by abnormal accumulation of reactive oxygen species and advanced glycation end products, has been widely reported. However, behavioral outcomes are still controversial and little is known about sex-dependent vulnerability. We performed a comprehensive behavioral and multifunctional screening of the chronic effects of low (50 mg/kg) and high (100 mg/kg) doses of d-galactose in 6-month-old male and female gold standard C57BL/6 mice. Twelve classical tests with convergent validity analyzed sensorimotor, emotional and cognitive domains, indicating the existence of thresholds of response. Distinct vulnerability patterns were found in a selective sex- and dose-dependent manner. In males, d-galactose induced sensorimotor impairment and immunoendocrine senescence, but the low dose resulted in improved learning and memory. Oppositely, d-galactose-treated females exhibited a dose dependent worse motor and spatial learning, but improved memory. Behavioral outcome items point at distinct neuronal substrates underlying the functional capacity of d-galactose-treated animals to meet task-dependent performance demands. They support that males and females can be regarded as two exceptional natural scenarios to study the functional interplay in the cross talk of homeostatic networks in aging. PMID- 29471513 TI - The genetic correlation between scapula shape and shoulder lesions in sows. AB - Shoulder lesions and body condition of sows at weaning have both environmental and genetic causes. The traits can be scored at farm level, and following recording, the traits can be included in the breeding goal and directional selection can be applied. However, to further increase the genetic progress of these traits, it is advantageous to develop indicator traits on the selection candidates (test boars or gilts, not yet exhibiting the phenotype themselves). It has previously been suggested that the scapula morphology and the spine of scapula might be a key factor for the sow to develop shoulder lesions. In this study, we developed 11 novel traits describing the morphology of the shoulder blade based on computed tomography images from scanned test boars. These traits include the area, length, width, height, and volume of the shoulder blade as well as 6 traits obtained from principal component analysis, describing 80% of the variation observed for the scapula spine profile. The analyzed traits have moderate to high heritability (h2 from 0.29 to 0.78, SE = 0.06), low to medium genetic correlations with shoulder lesions (up to 0.4, SE = 0.1), and body condition scoring at weaning (up to 0.25, SE = 0.1). These novel phenotypes can now be recorded automatically and accurately prior to selection of the AI boars. If such recordings are included in multivariate genomic selection models, it is expected to improve the genetic progress of shoulder lesions and body condition score by weaning.

PMID- 29471516 TI - Optical spectral transmission to assess inflammation in hand and wrist joints of rheumatoid arthritis patients. AB - Objective: To develop an optical spectral transmission (OST) model to measure joint inflammation, and thus disease activity, as well as to evaluate (patho )physiological findings that could lead to misclassification of inflammation. Methods: Forty-six RA patients were included in this cross-sectional study, where US scores, duplicate OST measurements and 28-joint DAS (DAS28) were acquired. With US as a reference standard, the diagnostic performance of OST in detecting inflammation at the joint level was evaluated using receiver operating characteristic (ROC) curve analyses. At the patient level, correlations with US were analysed for DAS28 and OST, and at joint level for OST and tender and swollen joint counts (TJC and SJC, respectively). Joint pathology potentially influencing misclassification by OST [erosions, osteophytes, tendon (sheath) inflammation (ab)normal vasculature and chondrocalcinosis] was evaluated for significance in a multivariate nominal logistic regression model. Results: Diagnostic performance of OST was good for MCP [area under the ROC curve (AUC ROC) 0.88], PIP (AUC-ROC 0.83) and wrist (AUC-ROC 0.74) joints and for all joints together (AUC-ROC 0.85). At the patient level, DAS28 correlated very poorly (rho = 0.06) and OST moderately (rho = 0.54) with US. At the joint level, US correlation with OST was strong (rho = 0.64), with SJC it was weak (rho = 0.30) and with TJC it was very weak (rho = -0.02). Misclassification of inflammation by OST was relatively rare (17%). Dorsal erosions [odds ratio (OR) 4.0], osteophytes (OR 2.1) and extensor tendinitis (OR 4.6) increased the risk of underestimating inflammation of MCP and PIP joints and osteophytes (OR 3.0) also increased the risk of overestimating inflammation. Conclusion: OST is a sensitive, specific and objective technique to assess joints inflammation of the hands and wrists of RA patients, even though bone and tendon pathology increases the risk of misclassification. PMID- 29471517 TI - The role of the ground-glass opacity ratio in resected lung adenocarcinoma. AB - OBJECTIVES: The goal of this study was to investigate the role of the ground glass opacity (GGO) ratio in lung adenocarcinoma in predicting surgical outcomes. METHODS: Patients who underwent surgical resection for pulmonary adenocarcinoma between January 2004 and December 2013 were reviewed. The clinical data, imaging characteristics of nodules, surgical approaches and outcomes were analysed with a mean follow-up of 87 months. RESULTS: Of 789 enrolled patients, 267 cases were categorized as having a GGO ratio >=0.75; 522 cases were categorized as having a GGO ratio <0.75. The gender, tumour differentiation, epidermal growth factor receptor mutation, smoking habits, lymphovascular space invasion, tumour size, maximum standard uptake value and carcinoembryonic antigen levels were significantly different in the 2 groups. In the group with a GGO ratio >=0.75, 63.3% of the patients underwent sublobar resection (18.8% with a GGO ratio < 0.75, P <0.001). These patients had fewer relapses (2.2% for GGO ratio >=0.75, 26.8% for GGO ratio <0.75, P < 0.001) and a better 5-year survival rate (95.5% for GGO ratio >=0.75, 77.4% for GGO ratio <0.75, P < 0.001). None of the patients with a GGO ratio >=0.75 had lymph node involvement. The multivariable Cox regression analysis revealed that a GGO ratio <0.75 was an independent factor for postoperative relapse with a hazard ratio of 3.96. CONCLUSIONS: A GGO ratio >=0.75 provided a favourable prognostic prediction in patients with resected lung adenocarcinoma. Sublobar resection and lymph node sampling revealed a fair outcome regardless of tumour size. However, anatomical resection is still the standard approach for patients with tumours with a GGO ratio <0.75, size >2 cm. PMID- 29471518 TI - Differences between Supportive Music and Imagery and Music Listening during Outpatient Chemotherapy and Potential Moderators of Treatment Effects. AB - Background: Supportive music and imagery and music listening interventions have been effective in decreasing distress and improving mood in cancer patients receiving chemotherapy, but it is unclear whether the two interventions differ in their treatment benefits. Furthermore, previous studies have not examined moderators to determine which subgroup(s) of patients may benefit most from each intervention. Objective: To examine the effects of supportive music and imagery compared with preferred music listening on responsiveness to music therapy, distress, anxiety and depression, and benefit finding. A secondary purpose was to explore sense of coherence and locus of control as potential moderators of intervention effectiveness. Methods: A single-session, two-group comparative effectiveness randomized trial in two cancer centers. Patients were randomized to supportive music and imagery or preferred music listening during outpatient chemotherapy treatment. Data were collected at baseline and immediately after the 45-minute session. ANCOVA models were used to determine main effects of intervention as well as pairing potential moderators with group assignment to explore differences in intervention effects by moderator. Results: There were differential effects between the two interventions with the supportive music and imagery group scoring higher in responsiveness to music therapy and benefit finding. The music listening group scores indicated lower distress. The exploratory moderating analyses suggested Health Locus of Control-Internal and Sense of Coherence influenced intervention effectiveness. Conclusions: Music and imagery and preferred music listening experiences may serve different therapeutic purposes, access and activate different patient resources, and may be helpful at different stages of treatment. PMID- 29471519 TI - Higher Risk of Abdominal Obesity, Elevated Low-Density Lipoprotein Cholesterol, and Hypertriglyceridemia, but not of Hypertension, in People Living With Human Immunodeficiency Virus (HIV): Results From the Copenhagen Comorbidity in HIV Infection Study. AB - Background: People living with human immunodeficiency virus (PLWH) are characterized by excess risk of cardiovascular diseases (CVD) and CVD risk factors compared to uninfected individuals. We investigated the association between HIV infection and abdominal obesity, elevated low-density lipoprotein cholesterol (LDL-C), hypertriglyceridemia, and hypertension in a large cohort of predominantly well-treated PLWH and matched controls. Methods: 1099 PLWH from the Copenhagen Co-morbidity in HIV Infection Study and 12 161 age- and sex-matched uninfected controls from the Copenhagen General Population Study were included and underwent blood pressure, waist, hip, weight, and height measurements and nonfasting blood samples. We assessed whether HIV was independently associated with abdominal obesity, elevated LDL-C, hypertriglyceridemia, and hypertension using logistic regression models adjusted for known risk factors. Results: HIV infection was associated with higher risk of abdominal obesity (adjusted odds ratio [aOR], 1.92 [1.60-2.30]) for a given body mass index, elevated LDL-C (aOR, 1.32 [1.09-1.59]), hypertriglyceridemia (aOR, 1.76 [1.49-2.08]), and lower risk of hypertension (aOR, 0.63 [0.54-0.74]). The excess odds of abdominal obesity in PLWH was stronger with older age (p interaction, 0.001). Abdominal obesity was associated with elevated LDL-C (aOR, 1.44 [1.23-1.69]), hypertension (aOR, 1.32 [1.16-1.49]), and hypertriglyceridemia (aOR, 2.12 [1.86-2.41]). Conclusions: Abdominal obesity was associated with proaterogenic metabolic factors including elevated LDL-C, hypertension, and hypertriglyceridemia and remains a distinct HIV related phenotype, particularly among older PLWH. Effective interventions to reduce the apparent detrimental impact on cardiovascular risk from this phenotype are needed. PMID- 29471520 TI - Effect of exposure to second-hand smoke from husbands on biochemical hyperandrogenism, metabolic syndrome and conception rates in women with polycystic ovary syndrome undergoing ovulation induction. AB - STUDY QUESTION: Does second-hand smoke (SHS) exposure from husbands have adverse effects on sex hormones, metabolic profiles, clinical phenotypes and fertility outcomes in women with polycystic ovary syndrome (PCOS) undergoing ovulation induction? SUMMARY ANSWER: SHS exposure is associated with worsened biochemical hyperandrogenism, higher incidence of metabolic syndrome and reduced conception rates in women with PCOS. WHAT IS KNOWN ALREADY: Smoking in women impairs fecundity at some stages of the reproductive process including folliculogenesis, embryo transport, endometrial angiogenesis and uterine blood flow. Yet little is known about the hazard of SHS exposure in women with PCOS. STUDY DESIGN, SIZE, DURATION: This study was a secondary analysis of the Polycystic Ovary Syndrome Acupuncture and Clomiphene Trial (PCOSAct), a large randomized controlled trial conducted at 27 hospitals from 2012 to 2015 in mainland China. PARTICIPANTS/MATERIALS, SETTING, METHODS: Out of 1000 women with PCOS, SHS exposure status were available in 500 women, of whom 271 women were non-exposed and 229 exposed to cigarette smoke (170 women <=10 cigarettes per day as low-SHS exposed and 59 women >10 cigarettes per day as high-SHS exposed). We compared circulating sex steroids, glucose and lipid metabolism, metabolic syndrome and phenotypes, fertility and obstetric outcomes between non-exposed and exposed women. MAIN RESULTS AND THE ROLE OF CHANCE: Women exposed to SHS, compared to non exposed women, had a higher serum total testosterone (1.7 vs 1.5 nmol/L, P = 0.01), free androgen index (5.7 vs 4.0, P = 0.001) and lower sex hormone binding globulin (30.1 vs 35.6 nmol/L, P = 0.03). Metabolic syndrome, but not other phenotypes, was more frequent in exposed women as compared to non-exposed women (21.8 vs 13.3%, adjusted odds ratio (OR)=1.66; 95% CI, 1.02-2.71, P = 0.04). Ovulation rates between exposed and non-exposed groups were not significantly different (76.9 vs 82.9%, adjusted OR=0.72; 95% CI, 0.45-1.15, P = 0.17). Conception rates were significant lower in the exposed group (26.6 vs 36.9%; adjusted OR=0.61; 95% CI, 0.41-0.91; P = 0.01), while clinical pregnancy and live birth rates showed a similar trend that was not statistically significant. Gestational age, birth weight and other obstetric outcomes were not affected by SHS exposure. LIMITATIONS, REASONS FOR CAUTION: Data on SHS exposure were missing in 50% of the women. We did not assay serum nicotine or cotinine levels to quantify the SHS exposure status. WIDER IMPLICATIONS OF THE FINDINGS: These data suggest that smoking partners of infertile women with PCOS who seek treatment should be advised to quit smoking.

PMID- 29471521 TI - Variable response of nirK and nirS containing denitrifier communities to long term pH manipulation and cultivation. AB - Denitrification is a key process responsible for the majority of soil nitrous oxide (N2O) emissions but the influences of pH and cultivation on the soil denitrifier community remain poorly understood. We hypothesised that the abundance and community structure of the total bacterial community and bacterial denitrifiers would be pH sensitive and that nirK and nirS containing denitrifiers would differ in their responses to change in pH and cultivation. We investigated the effect of long-term pH-adjusted soils (ranging from pH 4.2 to 6.6) under different lengths of grass cultivation (one, two and three years of ley grass) on the general bacterial and denitrifier functional communities using 16S rRNA, nirK and nirS genes as markers. Denitrifier abundance increased with pH, and at pH below 4.7 there was a greater loss in nirS abundance per unit drop in pH than soils above this threshold pH. All community structures responded to changes in soil pH, while cultivation only influenced the community structure of nirK. These differences in denitrifier responses highlight the importance of considering both nirK and nirS gene markers for estimating denitrifier activity. Identifying such thresholds in response of the microbial community to changes in pH is essential to understanding impacts of management or environmental change.

Here, we aimed to identify differentially expressed (DE) genes in the liver tissues of fattening Merino lambs and differences in metabolites accumulated in plasma to identify modified metabolic pathways as a consequence of milk restriction during the suckling period. Twenty-four male Merino lambs (4.81 +/- 0.256 kg) were divided into 2 groups (n = 12 per dietary treatment). The first group (ad libitum, ADL) was kept permanently with the dams, whereas the other group (restricted, RES) was milk restricted. When they reached 15 kg of live body weight (LBW), all the animals were offered the same complete pelleted diet at the same level (35 g DM/kg LBW per day) to ensure no differences in dry matter intake. All the lambs were harvested when they reached 27 kg of LBW. For transcriptomic analysis, 4 liver samples from each group (8 samples in total) were selected for RNA sequencing (RNA-seq), and plasma samples from all animals (24 samples in total) were used to perform a nontargeted metabolomic analysis on a hybrid quadrupole-time-of-flight mass spectrometer coupled to an ultra-high performance liquid chromatographic system (UHPLC/QTOF-MS). Thirty-eight DE annotated genes were identified by RNA-seq, with 23 DE genes being down-regulated and 15 up-regulated in the liver of RES lambs relative to the ADL group (P < 0.10). Also, the metabolomic assay identified 38 differentially accumulated compounds (P < 0.10). In general, those genes and pathways involved in protein synthesis or protease inhibitors were down-regulated in the RES group, whereas those related to proteolytic degradation were up-regulated, thus suggesting a higher catabolism of proteins in these lambs. RES lambs showed over-expression of xenobiotic metabolism pathways, whereas those genes related to beta-oxidation of fatty acids were down-regulated. According to the data obtained, early feed restriction during the suckling period of Merino lambs promoted long-term effects on both the hepatic transcriptomic profile and plasma metabolic profile, which might have modified fatty acids metabolism, catabolism of proteins, and detoxification of xenobiotics, thus reducing feed efficiency during the fattening period. PMID- 29471525 TI - Rightsizing root phenotypes for drought resistance. AB - I propose that reduced root development would be advantageous for drought resistance in high-input agroecosystems. Selection regimes for crop ancestors and landraces include multiple stresses, intense competition, and variable resource distribution, which favored prolific root production, developmental plasticity in response to resource availability, and maintenance of unspecialized root tissues. High-input agroecosystems have removed many of these constraints to root function. Therefore, root phenotypes that focus on water capture at the expense of ancestral adaptations would be better suited to high-input agroecosystems. Parsimonious architectural phenotypes include fewer axial roots, reduced density of lateral roots, reduced growth responsiveness to local resource availability, and greater loss of roots that do not contribute to water capture. Parsimonious anatomical phenotypes include a reduced number of cortical cell files, greater loss of cortical parenchyma to aerenchyma and senescence, and larger cortical cell size. Parsimonious root phenotypes may be less useful in low-input agroecosystems, which are characterized by multiple challenges and trade-offs for root function in addition to water capture. Analysis of the fitness landscape of root phenotypes is a complex challenge that will be aided by the development of robust functional-structural models capable of simulating the dynamics of root soil interactions.

AB - The aim of the current study was to determine nutrient digestibility, VFA production, N metabolism, and CH4 production of canola (Brassica napus L.), rapeseed (B. napus L.), turnip (Brassica rapa L.), and annual ryegrass (Lolium multiflorum Lam.) fed with orchardgrass (Dactylis glomerata L.) in continuous culture. Diets were randomly assigned to fermentors in a 4 * 4 Latin square design using 7 d for adaptation and 3 d for collection. Diets were: 1) 50% orchardgrass + 50% annual ryegrass (ARG); 2) 50% orchardgrass + 50% canola (CAN); 3) 50% orchardgrass + 50% rapeseed (RAP); and 4) 50% orchardgrass + 50% turnip (TUR). Feedings (82 g DM/d) occurred four times daily throughout 4, 10-d periods at 730, 1030, 1400, and 1900 h. Methane samples were collected every 10 min using a photoacoustic gas analyzer (LumaSense Technologies, Inc.; Santa Clara, CA) during the last 3 d of the experiment. Effluent samples were collected on d 8, 9, and 10, composited by fermentor, and analyzed for VFA and pH as well as DM, OM, CP, and fiber fractions for determination of nutrient digestibility. Forage samples were analyzed for CP, NDF, ADF, minerals, and glucosinolate (GLS) concentrations. Data were analyzed using the GLIMMIX procedure of SAS. Apparent DM, OM, and NDF digestibilities and true DM and OM digestibilities were similar (P > 0.28) among diets (45.1, 63.2, 44.1, 67.1, and 87.2%, respectively). Total VFA (87.2 mol/100 mol), pH (6.47), and acetate (A: 44.6 mol/100 mol) were also not different (P > 0.20) among diets. The A:P (P = propionate) ratio was greater (P < 0.01) in ARG and CAN than RAP and TUR. Daily CH4 production was greater (P < 0.01) in ARG than all other diets (68.9 vs. 11.2 mg/d). Methane, whether expressed as g per g of OM, NDF, digestible OM, or digestible NDF fed was greatest (P < 0.01) in ARG but similar (P > 0.18) among brassica diets. A significant negative correlation was observed between total GLS and CH4 production. However, when multiple regression analysis on CH4 production was completed, neither total GLS nor individual GLS were a significant component of the model. Addition of brassicas provided similar nutrient digestibility to ARG while reducing daily CH4 production, potentially making brassicas an alternative for ARG in pasture-based ruminant diets.

AB - Objective: Mealtime emotional climate (MEC) is related to parent feeding and mental health, and possibly to child food consumption. However, MEC has been inconsistently assessed with a variety of coding schemes and self-report instruments, and has not been examined longitudinally. This study aims to characterize MEC systematically using an observational, count-based coding scheme; identify whether parent feeding or mental health predict MEC; and examine whether MEC predicts child food consumption and weight. Methods: A subsample of parents (n = 74) recruited from a larger study completed questionnaires when children were about 37 months, participated in a home visit to videotape a mealtime when children were about 41 months, and completed questionnaires again when children were about 51 months old. Maternal and child positive and negative emotions were coded from videotaped mealtimes. Observational data were submitted to cluster analyses, to identify dyads with similar emotion expression patterns, or MEC. Logistic regression was used to identify predictors of MEC, and Analysis of Covariance was used to examine differences between MEC groups. Results: Dyads were characterized as either Positive Expressers (high positive, low negative emotion) or All Expressers (similar positive and negative emotion). Increased food involvement feeding practices were related to decreased likelihood of being an All Expresser. Positive Expressers reported that their children ate more healthy food, compared with All Expressers. Conclusions: Observed MEC is driven by maternal emotion, and may predict child food consumption. Food involvement may promote positive MEC. Improving MEC may increase child consumption of healthy foods.

AB - Background: Previous studies demonstrated that prognosis of germline deficiency in mismatch repair protein (dMMR) was different from that of sporadic dMMR. The underlying mechanism has not been studied. Methods: From a prospectively maintained database, we collected dMMR colorectal cancer (CRC) patients identified by postoperative immunohistochemistry screening. According to genetic test, patients were grouped as Lynch-associated or sporadic dMMR. We compared the clinical-pathological features, prognosis, and immunoreactive differences between the two groups. By whole-exome sequencing and neoantigen detection pipeline, mutational frequencies and neoantigen burdens were also compared. All statistical tests were two-sided. Results: Sixty-seven sporadic dMMR and 85 Lynch-associated CRC patients were included in the study. Sporadic dMMR patients were older (P < .001) and their tumors were poorly differentiated (P = .03). The survival was better in the Lynch-associated group (P = .001). After adjustment, the difference still remained statistically significant (hazard ratio = 0.29, 95% confidence interval = 0.09 to 0.95, P = .04). The scores of Crohn's-like reaction (CRO; P < .001), immunoreactions in the invasive margin (IM; P = .01), tumor stroma (TS; P = .009), and cancer nest (CN; P = .02) of the Lynch-associated group were statistically significantly higher. The numbers of CD3+, CD8+, Foxp3+ tumor infiltrating lymphocytes (TILs) in IM; CD3+, CD4+ TILs in TS; and CD3+, CD4+, CD8+ TILs in CN were statistically significantly higher in Lynch-associated dMMR patients. Based on the 16 patients who under went whole-exome sequencing, there were also more somatic mutations and neoantigen burdens in the Lynch-associated group compared with the sporadic dMMR group (439/pt vs 68/pt, P = .006; 628/pt vs 97/pt, P = .009). Conclusions: There are heterogeneities in dMMR CRCs. Lynch associated dMMR patients present with more somatic mutations and neoantigens compared with sporadic dMMR, which probably results in stronger immunoreactions and survival improvement.

AB - Background: Carbon monoxide is the leading cause of mortality from unintentional poisoning in Slovenia. It has been shown that carbon monoxide levels can rise in wood pellet storerooms because of chemical degradation of pellets, even at room temperature. We present a case of lethal carbon monoxide poisoning with first responder carbon monoxide exposure. Aims: To highlight the dangers rescuers face during interventions in pellet storerooms and the need for preventive precautions. Case report: Paramedics and firemen were called to help an unconscious man in a wood pellet storeroom. Firemen immediately evacuated the victim and paramedics began cardiopulmonary resuscitation. Soon after, rescuers complained of dizziness and developed headache, nausea and fatigue. A carbon monoxide level of 600 ppm was detected. Three rescuers were treated with 100% oxygen. Blood carboxyhaemoglobin levels were up to 8% on arrival at the emergency department. The victim died and autopsy confirmed carbon monoxide poisoning. Conclusions: First responders have to be aware of the dangers of carbon monoxide in wood pellet storerooms. Basic precautions and safety instructions should be followed before entering a wood pellet storeroom. Carbon monoxide should be measured before entering and self-contained breathing apparatus should be used. Wood pellet storerooms require continuous ventilation and should be equipped with carbon monoxide detectors. PMID- 29471532 TI - Hyperparasitism and Non-Nidicolous Mating by Male Ixodes angustus Ticks (Acari: Ixodidae). AB - Ixodes angustus (Neumann) (Acari: Ixodidae) is considered to be a nidicolous tick in that the entire life cycle can be completed in the host nest. Males of this tick have been reported to be rare on hosts because most mating occurs in the host nest and males typically do not feed on hosts. Collections of I. angustus in Alaska departed slightly from this paradigm in that nine males were collected from hosts, mostly in copulation with females that were attached to mammalian hosts. Non-nidicolous mating was therefore more common in I. angustus collected in this study than has been reported previously. A hyperparasitic male I. angustus was found firmly attached via its hypostome and chelicerae to the ventral idiosoma of a partially engorged female I. angustus that was attached to, and feeding on, an American red squirrel, Tamiasciurus hudsonicus (Erxleben). This hyperparasitic interaction is discussed and illustrated with a Scanning Electron Micrograph. PMID- 29471533 TI - Reproducibility of work ability and work functioning instruments. AB - Background: Work ability (WA) and work functioning (WF) instruments can be useful in occupational health practice. The reproducibility of both instruments is important to their relevance for daily practice. Clinimetrics concerns the methodological and statistical quality of instruments and their performance in practice. Aims: To assess the reproducibility of WA and WF instruments. Methods: Dutch workers completed a questionnaire containing WA questions and the WF questionnaire twice with a 7-day interval between. The questionnaire included an appraisal of current general, physical and mental/emotional WA (0-10) and the composite WF questionnaire of 49 items (0-100). We measured reproducibility, reliability and agreement by calculating the intraclass correlation coefficient (ICC), the standard error of measurement (SEM) and the smallest detectable change (SDC). Results: The answers of 104 respondents were available for analysis. General, physical and mental/emotional WA had ICC values of 0.52, 0.69 and 0.56, respectively. For WF, the ICC value was 0.85. For general WA, the SEM was 0.71. For physical and mental/emotional WA, the SEMs were 0.75 and 0.74, respectively. For general, physical and mental/emotional WA, the SDC was 1.98, 2.09 and 2.05 respectively. The SEM of the WF score was 4.78, and the SDC was 13.25. Conclusions: The WA questions showed moderate reliability, while the WF instrument showed good reliability. Occupational health professionals can use the SDCs of the instruments to monitor changes in WA and WF in workers over time. PMID- 29471534 TI - Cypermethrin Promotes Lung Cancer Metastasis via Modulation of Macrophage Polarization by Targeting MicroRNA-155/Bcl6. AB - Cypermethrin (CYM), a type II pyrethroid, is widely used as an insecticide for agriculture and household. Cumulative evidence indicates that acute and chronic exposure to CYM might cause a number of health problems, such as cancer and neuronal system diseases. However, the molecular mechanism underlying this pathology is not known. The main objective of this study was to define the effects of CYM on macrophages and the implication of such effects in cancer metastasis and the potential mechanism involved. The effects of CYM on the macrophages were evaluated by detecting the expression of M1 and M2 macrophage polarization markers through ELISA, quantitative RT-PCR, and Western blot assay. Transwell and wound healing assays were used to test the migration of lung cancer cells after exposure to CYM in vitro and a metastasis animal model in vivo. Treatment with CYM significantly suppressed lipopolysaccharide (LPS)-induced M1 macrophage polarization and promoted a shift toward M2 macrophage status. Mechanistically, CYM downregulated miR-155 significantly, leading to enhanced expression of its target gene Bcl6, thereby reducing the expression of mitogen activated protein kinase 4 (MKK4), an upstream kinase of c-Jun N-terminal kinases (JNK), and inhibiting JNK activation. Impaired JNK activation thus promoted a shift in macrophage polarization from the M1 to the M2 phenotype. Finally, CYM treated macrophages promoted metastasis of Lewis lung cancer cells in both in vitro and in vivo models. Taken together, our findings show that CYM is able to inhibit the M1 polarization and promote the macrophages to the M2 phenotype, which plays an important role in tumor metastasis. PMID- 29471535 TI - The MEDIA model: An innovative method for digitizing and training community members to facilitate an HIV prevention intervention. AB - As human immunodeficiency virus (HIV) continues to disproportionately affect African American women, practitioners remain committed to developing innovative strategies to reduce HIV prevalence. These strategies include training community organizations, such as churches, and utilizing digital media to make intervention dissemination more sustainable. This article describes one such effort to train lay community members within predominantly Black churches in Atlanta, GA, to implement an HIV prevention intervention. Lay educators were trained by translating a face-to-face Training of Facilitators (TOF) to a digital platform using the MEDIA (Motivate-Engage-Digitize-Implement-Assess) model. Formative evaluations, consultation with experts in the digital platform of choice, and the experience of two P4 for Women Master Trainers informed our translation. The model guided the translation process as our research team worked alongside topical experts and a production company to develop storyboards for core curriculum activities, which were later scripted and filmed with mock participants. A user guide, toolkit, and program website were also developed as supplemental materials to accompany the video training. Lessons learned from this study indicate future attempts at digitizing TOFs should keep in mind that digitization can be a time-consuming process, pilot testing in the new format is necessary even for a previously tested intervention, and the structure provided by facilitators in face-to-face training must be embedded into the format of digitized trainings. PMID- 29471536 TI - Variation Across Mitochondrial Gene Trees Provides Evidence for Systematic Error: How Much Gene Tree Variation Is Biological? AB - The use of large genomic data sets in phylogenetics has highlighted extensive topological variation across genes. Much of this discordance is assumed to result from biological processes. However, variation among gene trees can also be a consequence of systematic error driven by poor model fit, and the relative importance of biological vs. methodological factors in explaining gene tree variation is a major unresolved question. Using mitochondrial genomes to control for biological causes of gene tree variation, we estimate the extent of gene tree discordance driven by systematic error and employ posterior prediction to highlight the role of model fit in producing this discordance. We find that the amount of discordance among mitochondrial gene trees is similar to the amount of discordance found in other studies that assume only biological causes of variation. This similarity suggests that the role of systematic error in generating gene tree variation is underappreciated and critical evaluation of fit between assumed models and the data used for inference is important for the resolution of unresolved phylogenetic questions. PMID- 29471538 TI - Novel roles of ascorbate in plants: induction of cytosolic Ca2+ signals and efflux from cells via anion channels. AB - Ascorbate is not often considered as a signalling molecule in plants. This study demonstrates that, in Arabidopsis roots, exogenous l-ascorbic acid triggers a transient increase of the cytosolic free calcium activity ([Ca2+]cyt.) that is central to plant signalling. Exogenous copper and iron stimulate the ascorbate induced [Ca2+]cyt. elevation, while cation channel blockers, free radical scavengers, low extracellular [Ca2+], transition metal chelators, and removal of the cell wall inhibit this reaction. These data show that apoplastic redox-active transition metals are involved in the ascorbate-induced [Ca2+]cyt. elevation. Exogenous ascorbate also induces a moderate increase in programmed cell death symptoms in intact roots, but it does not activate Ca2+ influx currents in patch clamped root protoplasts. Intriguingly, the replacement of gluconate with ascorbate in the patch-clamp pipette reveals a large ascorbate efflux current, which shows sensitivity to the anion channel blocker, anthracene-9-carboxylic acid (A9C), indicative of the ascorbate release via anion channels. EPR spectroscopy measurements demonstrate that salinity (NaCl) triggers the accumulation of root apoplastic ascorbyl radicals in an A9C-dependent manner, confirming that l-ascorbate leaks through anion channels under depolarization. This mechanism may underlie ascorbate release, signalling phenomena, apoplastic redox reactions, iron acquisition, and control the ionic and electrical equilibrium (together with K+ efflux via GORK channels). PMID- 29471537 TI - The C-terminal helix of ribosomal P stalk recognizes a hydrophobic groove of elongation factor 2 in a novel fashion. AB - Archaea and eukaryotes have ribosomal P stalks composed of anchor protein P0 and aP1 homodimers (archaea) or P1*P2 heterodimers (eukaryotes). These P stalks recruit translational GTPases to the GTPase-associated center in ribosomes to provide energy during translation. The C-terminus of the P stalk is known to selectively recognize GTPases. Here we investigated the interaction between the P stalk and elongation factor 2 by determining the structures of Pyrococcus horikoshii EF-2 (PhoEF-2) in the Apo-form, GDP-form, GMPPCP-form (GTP-form), and GMPPCP-form bound with 11 C-terminal residues of P1 (P1C11). Helical structured P1C11 binds to a hydrophobic groove between domain G and subdomain G' of PhoEF-2, where is completely different from that of aEF-1alpha in terms of both position and sequence, implying that such interaction characteristic may be requested by how GTPases perform their functions on the ribosome. Combining PhoEF-2 P1-binding assays with a structural comparison of current PhoEF-2 structures and molecular dynamics model of a P1C11-bound GDP form, the conformational changes of the P1C11 binding groove in each form suggest that in response to the translation process, the groove has three states: closed, open, and release for recruiting and releasing GTPases. PMID- 29471539 TI - Breaking Down Barriers to the Utilization of Standardized Tests and Outcome Measures in Acute Care Physical Therapist Practice: An Observational Longitudinal Study. AB - Background: Standardized tests and outcome measures (STOM) have not been consistently implemented as part of most physical therapists' practice. Incidence of STOM use among physical therapists at Beth Israel Deaconess Medical Center was similar to low levels cited nationally among acute care physical therapists. Targeted knowledge translation (KT) strategies have been suggested to promote the application of research evidence into clinical decision making. Purpose: The purpose of this quality improvement (QI) effort was to implement a series of interventions aimed at increasing both use and interpretation of STOM by physical therapists practicing in acute care. Design: This study used an observational longitudinal design. Methods: A literature review identified current barriers and facilitators to the use of STOM by physical therapists. KT strategies were tailored to the practice setting in order to target barriers and promote facilitators to the use of STOM. Data were collected through retrospective chart review at baseline and then subsequently at 4 periods following the implementation of the QI project. Results: A statistically significant increase in both the use (primary outcome) and interpretation (secondary outcome) of STOM was observed following the implementation of KT strategies. The increase was sustained at all subsequent measurement periods. Limitations: Limitations include the lack of a control group and the small number of setting- and diagnosis specific STOM available for use by physical therapists practicing in acute care. Conclusions: Implementation of KT strategies was associated with an increase in the frequency of use and interpretation of STOM. Similar QI efforts are feasible in any acute care physical therapy department and potentially other settings.

PMID- 29471541 TI - The Caucasian Nasal Septum: An In Vivo Computed Tomography Study. AB - Background: The nasal septum is composed of cartilaginous and bony components and an understanding of each component volume is essential in both functional and cosmetic surgery. Objectives: We sought to radiographically measure septal dimensions on cross sectional computer tomography (CT) images, establishing average parameters for normal anatomy among a single, Caucasian population group. Methods: One hundred and fifty consecutive sinus CT scan images were examined and 100 cases with appropriate sagittal views were included in the study. On each septum, the sagittal CT images were assessed and 14 points were identified and 23 lengths measured and tabulated. Trigonometric formulae were used to accurately calculate surface areas of 11 resulting triangles which constituted the components of the nasal septum. Results: Measurements from 100 patients were included, with a mean age of 50.2 years, constituting 47 males and 53 females. Our surface area mapping established the following areas for both males and females respectively (mm2): quadrangular cartilage 1148 and 981; vomer 894 and 741; perpendicular plate of ethmoid bone 1244 and 1006; and total surface area 3287 and 2728. Our only statistically significant comparison in the series was found in the female series when age and reducing quadrilateral cartilage size were compared, highlighting reducing size with age (P = 0.04). Conclusions: The study presents the largest published data series representing nasal septal measurements on CT images in a living Caucasian population. Our data demonstrates that septal size remains constant after adolescence, throughout our age-varied series (18-79 years), except in the female population where the quadrilateral cartilage reduces in size with age. Level of Evidence 4: PMID- 29471543 TI - Current and Future Potential Risk of Establishment of Grapholita molesta (Lepidoptera: Tortricidae) in Washington State. AB - The oriental fruit moth, Grapholita molesta (Busck) (Lepidoptera: Tortricidae), is a primary pest of stone fruits that cause significant economic damage. Larvae, which enter the host plant through shoot tips, damage shoots, and ripe fruits. Native to Asia, this pest now occurs in many fruit-growing countries, including the United States and Canada. Though the pest was previously reported from many states within the United States, its current distribution and the environmental variables that influence its distribution are not properly identified. The objectives of this study were to 1) identify the environmental factors associated with G. molesta current distribution, 2) predict the current distribution of G. molesta in Washington State (WA) using Maxent and Climex models, 3) identify those areas within WA best suited for establishment of pest free zones, areas of low pest prevalence, and pest free production areas, and 4) identify regions most at risk for further expansion of G. molesta populations as a function of climate change. The current models predicted a small portion of central WA is suitable to support G. molesta, which is consistent with observed distributions. However, climate change models predict that more areas will become suitable for the pest. These results indicate that action should be taken to monitor and reduce current populations of G. molesta to stem its potential expansion into the major commercial tree fruit production areas in the state. PMID- 29471542 TI - Specialized Pro-Resolving Lipid Mediators Regulate Ozone-Induced Pulmonary and Systemic Inflammation. AB - Exposure to ozone (O3) induces lung injury, pulmonary inflammation, and alters lipid metabolism. During tissue inflammation, specialized pro-resolving lipid mediators (SPMs) facilitate the resolution of inflammation. SPMs regulate the pulmonary immune response during infection and allergic asthma; however, the role of SPMs in O3-induced pulmonary injury and inflammation is unknown. We hypothesize that O3 exposure induces pulmonary inflammation by reducing SPMs. To evaluate this, male C57Bl/6J mice were exposed to filtered air (FA) or 1 ppm O3 for 3 h and necropsied 24 h after exposure. Pulmonary injury/inflammation was determined by bronchoalveolar lavage (BAL) differentials, protein, and lung tissue cytokine expression. SPMs were quantified by liquid chromatography tandem mass spectrometry and SPM receptors leukotriene B4 receptor 1 (BLT-1), formyl peptide receptor 2 (ALX/FPR2), chemokine-like receptor 1 (ChemR23), and SPM generating enzyme (5-LOX and 12/15-LOX) expression were measured by real time PCR. 24 h post-O3 exposure, BAL PMNs and protein content were significantly increased compared to FA controls. O3-induced lung inflammation was associated with significant decreases in pulmonary SPM precursors (14-HDHA, 17-HDHA), the SPM PDX, and in pulmonary ALX/FPR2, ChemR23, and 12/15-LOX expression. Exogenous administration of 14-HDHA, 17-HDHA, and PDX 1 h prior to O3 exposure rescued pulmonary SPM precursors/SPMs, decreased proinflammatory cytokine and chemokine expression, and decreased BAL macrophages and PMNs. Taken together, these data indicate that O3-mediated SPM reductions may drive O3-induced pulmonary inflammation.

AB - Power is a critical concept to understand and transform health policy and systems. Power manifests implicitly or explicitly at multiple levels-local, national and global-and is present at each actor interface, therefore shaping all actions, processes and outcomes. Analysing and engaging with power has important potential for improving our understanding of the underlying causes of inequity, and our ability to promote transparency, accountability and fairness. However, the study and analysis of the role of power in health policy and systems, particularly in the context of low- and middle-income countries, has been lacking. In order to facilitate greater engagement with the concept of power among researchers and practitioners in the health systems and policy realm, we share a broad overview of the concept of power, and list 10 excellent resources on power in health policy and systems in low- and middle-income countries, covering exemplary frameworks, commentaries and empirical work. We undertook a two-stage process to identify these resources. First, we conducted a collaborative exercise involving crowdsourcing and participatory validation, resulting in 24 proposed articles. Second, we conducted a structured literature review in four phases, resulting in 38 articles reviewed. We present the 10 selected resources in the following categories to bring out key facets of the literature on power and health policy and systems-(1) Resources that provide an overarching conceptual exploration into how power shapes health policy and systems, and how to investigate it; and (2) examples of strong empirical work on power and health policy and systems research representing various levels of analyses, geographic regions and conceptual understandings of power. We conclude with a brief discussion of key gaps in the literature, and suggestions for additional methodological approaches to study power. PMID- 29471545 TI - High-protein distillers dried grains with solubles produced using a novel front end-back-end fractionation technology has greater nutritional value than conventional distillers dried grains with solubles when fed to growing pigs. AB - Two experiments were conducted to determine the standardized ileal digestibility (SID) of CP and AA, apparent total tract digestibility (ATTD) of GE, and DE and ME in conventional distillers dried grains with solubles (DDGS-CV) and in a novel source of high-protein distillers dried grains with solubles (DDGS-HP) produced by Lincolnway Energy (Nevada, IA). In Exp. 1, 18 barrows (initial BW: 72.47 +/- 9.16 kg) that had a T-cannula installed in the distal ileum were allotted to a completely randomized design with 3 diets and 6 replicate pigs per diet. A nitrogen-free diet and 2 diets that contained cornstarch and DDGS-CV or DDGS HPLincolnway as the sole source of CP and AA were formulated. Diets were fed to pigs for 7 d, and ileal digesta were collected on days 6 and 7 of each period. The SID for Leu, Lys, Met, Phe, and Glu was greater (P < 0.05) in DDGS HPLincolnway than in DDGS-CV, and the SID of Ile, Val, and total indispensable AA, as well as the SID of Tyr, tended to be greater (P < 0.10) in DDGS HPLincolnway than in DDGS-CV. No difference between DDGS-CV and DDGS-HPLincolnway was observed for the SID of CP and all other AA. In Exp. 2, 24 barrows (initial BW: 52.80 +/- 2.55 kg) were housed individually in metabolism crates and randomly allotted to 1 of 3 diets. A corn-based basal diet (97.25% corn) and 2 diets that contained corn and DDGS-CV or corn and DDGS-HPLincolnway were formulated. Each diet was fed to 8 pigs. Feces and urine were collected using the marker to marker approach with 7-d adaptation and 5-d collection periods. The DE and ME in DDGS-CV and DDGS-HPLincolnway were calculated using the difference procedure. The DE and ME in DDGS-HPLincolnway on an as-fed basis were greater (P < 0.05) than in corn and DDGS-CV, but the ATTD of GE in DDGS-HPLincolnway and DDGS-CV was less (P < 0.01) than in corn. In conclusion, the SID of some AA and the DE and ME in DDGS HPLincolnway were greater than in DDGS-CV.

Current hypotheses favor gene * environment interactions as supported by our recent report about DNA methylation changes during the onset of psychosis. Here, we conducted the first longitudinal transcriptomic analysis of blood samples from 31 at-risk individuals who later converted to psychosis and 63 at-risk individuals who did not. Individuals were followed for a maximum of 1 year. Blood samples were collected at baseline and at the end of follow-up and individuals served as their own controls. Differentially expressed genes between the 2 groups were identified using the RNA sequencing of an initial discovery subgroup (n = 15 individuals). The most promising results were replicated using high-throughput real-time qPCR in the whole cohort (n = 94 individuals). We identified longitudinal changes in 4 brain-expressed genes based on RNAseq analysis. One of these genes (CPT1A) was replicated in the whole cohort. The previously observed hypermethylation in NRP1 and GSTM5 during the onset of psychosis correlated with a decrease in corresponding gene expression. RNA sequencing also identified 2 co-expression networks that were impaired after conversion compared with baseline-the Wnt pathway including AKT1, CPT1A and semaphorins, and the Toll-like receptor pathway, related to innate immunity. This longitudinal study of transcriptomic changes in individuals with at-risk mental state revealed alterations during conversion to psychosis in pathways and genes relevant to schizophrenia. These results may be a first step toward better understanding psychosis onset. They may also help to identify new biomarkers and targets for disease-modifying therapeutic strategies.

PMID- 29471549 TI - Glutamate Dehydrogenase-Deficient Mice Display Schizophrenia-Like Behavioral Abnormalities and CA1-Specific Hippocampal Dysfunction. AB - Brain imaging has revealed that the CA1 subregion of the hippocampus is hyperactive in prodromal and diagnosed patients with schizophrenia (SCZ), and that glutamate is a driver of this hyperactivity. Strikingly, mice deficient in the glutamate synthetic enzyme glutaminase have CA1 hypoactivity and a SCZ resilience profile, implicating glutamate-metabolizing enzymes. To address this further, we examined mice with a brain-wide deficit in the glutamate-metabolizing enzyme glutamate dehydrogenase (GDH), encoded by Glud1, which should lead to glutamate excess due to reduced glutamate metabolism in astrocytes. We found that Glud1-deficient mice have behavioral abnormalities in the 3 SCZ symptom domains, with increased baseline and amphetamine-induced hyperlocomotion as a positive symptom proxy, nest building and social preference as a negative symptom proxy, and reversal/extradimensional set shifting in the water T-maze and contextual fear conditioning as a cognitive symptom proxy. Neuroimaging of cerebral blood volume revealed hippocampal hyperactivity in CA1, which was associated with volume reduction. Parameters of hippocampal synaptic function revealed excess glutamate release and an elevated excitatory/inhibitory balance in CA1. Finally, in a direct clinical correlation using imaging-guided microarray, we found a significant SCZ-associated postmortem reduction in GLUD1 expression in CA1. These findings advance GLUD1 deficiency as a driver of excess hippocampal excitatory transmission and SCZ symptoms, and identify GDH as a target for glutamate modulation pharmacotherapy for SCZ. More broadly, these findings point to the likely involvement of alterations in glutamate metabolism in the pathophysiology of SCZ. PMID- 29471550 TI - Phenotype-Genotype Correlation in Children with Neurofibromatosis Type 1. AB - Neurofibromatosis type 1 (NF1) is a common autosomal dominant disorder with an incidence of ~1 in 4,000 live births. Neurofibromin, the gene product, is ubiquitously expressed at high levels in the nervous system and functions as a tumor suppressor. Haploinsufficiency of neurofibromin through mutation leads to an increased risk of developing benign and malignant tumors in affected individuals. Although NF1 has complete penetrance, it displays considerable inter and intrafamilial variability in phenotypic expression which poses disease prediction and management problems. Some NF1 genotype-phenotype correlations have been described. To evaluate the genetic component of variable expressivity in NF1, we examined the phenotypic correlations between affected relatives in 52 NF1 patients from 45 families.

PMID- 29471551 TI - Bilateral Striatal Necrosis after Sydenham's Chorea in a 7-Year-Old Boy: A 2-Year Follow-Up. AB - Child bilateral striatal necrosis (BSN) is a rare and etiologically heterogeneous condition. An association with group A streptococcus (GAS) infection was previously reported in two cases of BSN in infancy and early childhood. We here report on a 7-year-old boy who developed chorea and dystonia 20 days after symptomatic recovery from Sydenham's chorea. Repeated brain magnetic resonance imaging scans, obtained before, soon after the onset of the post-Sydenham symptoms, and 1 year later were consistent with an evolution from bilateral striatal microbleeding to necrosis, and consequently reduced basal ganglia volume and enlargement of the frontal horns. No support was found for other possible autoimmune, infectious, metabolic, toxic or genetic etiologies for BSN. Prednisone treatment was instituted and continued for 1 year. Two years after the onset of the post-Sydenham symptoms, the child, although much improved, still has generalized dystonic-choreic movements. This case confirms and extends into school age, the link between GAS and BSN.

AB - OBJECTIVE: To elucidate organizational and human resource management-related drivers of community mental health services and home treatment in Germany. METHODS: Systematic review of psychiatric and organizational science literature, additional manual search. RESULTS: Relevant driver variables in community mental health services and home treatment have mostly been addressed. However, only a few have been evaluated and complex cause-and-effect models are missing so far. CONCLUSIONS: The proposed drivers, moderators, and throughputs should be integrated into an evaluation system that should be able to estimate effects of organizational and human resources on care-related and economic outcomes. PMID- 29471554 TI - [Day Surgery for Endoscopic Inguinal Hernia Repair]. AB - BACKGROUND: Whereas international guidelines recommend day surgery for endoscopic inguinal hernia repair, this approach is still controversial in Germany. In the light of international guidelines and at the request of patients, we have established total extraperitoneal patch plastic (TEP) surgery in the outpatient setting in our hospital. METHODS: A retrospective analysis of all unilateral TEP procedures carried out between January 2013 and December 2015 in our outpatient surgery, focused on postoperative complications, conversion to admission and rate of recurrence. Patient satisfaction with the outpatient setting was evaluated by telephone interview. RESULTS: In the 3 year period analysed, 164 patients were admitted for day surgery. Outpatient surgery was carried out in 152 patients, whereas 12 patients had to be admitted overnight due to circulatory disturbance, pain or bleeding. A total of 102 patients could be questioned for follow-up. Hematoma developed in 9 patients, and recurrence of hernia in 3 patients. Infections or seromas were not described or detected. 88 patients were very satisfied with the outpatient procedure, and 82 patients would clearly prefer day surgery again. CONCLUSIONS: Unilateral endoscopic hernia repair is safe and can be performed in the outpatient setting without increased risk. Satisfaction and acceptance by the patients is high. There is a dramatic difference between day surgery and inpatient procedure in the costs for hernia repair and this is one of the major reasons why outpatient endoscopic hernia repair is still rare in Germany. PMID- 29471555 TI - [Pregnancy after Obesity and Metabolic Surgery - Risks and Complications]. AB - The increasing prevalence of morbid obesity in Germany is associated with an increasing number of metabolic surgical interventions. Short-term surgical and long-term metabolic complications - such as nutrient deficiencies - are the main risks of metabolic surgery and the resulting malabsorption. Obesity, especially morbid obesity, is associated with a high incidence of female infertility. One important cause of female infertility in obese women is the polycystic ovary syndrome, with 6 - 10%. Metabolic surgery significantly increases the fertility of obese women. The positive effect of obesity surgery on weight loss, remission of comorbidities, psychological outcome and fertility (in comparison with the effect of conservative treatment) has led to an increase in the number of metabolic operations. Nutrient deficiencies after restrictive, combined and malabsorptive procedures must be considered. Prophylaxis of these deficiencies during pregnancy after obesity surgery must be based on intensive interdisciplinary treatment. The aim of this overview is to characterise the metabolic complications and their prophylaxis, which are specific for the various bariatric procedures and which, subsequently, require temporary or permanent surveillance and supplementation. PMID- 29471556 TI - ? PMID- 29471557 TI - Prospective Comparison of a Metal-Free Ceramic Total Knee Arthroplasty with an Identical Metal System. AB - AIMS: The aim of this open-label, prospective, short-term study was to carry out an initial comparison of a completely metal-free ceramic with a geometrically identical metallic arthroplasty over a 1-year follow-up period. METHODS: This study investigates a completely metal-free system using a composite matrix material containing aluminum oxide (Al2O3, BPK-S Integration, Peter Brehm GmbH, Weisendorf, Germany) or zirconium oxide (ZrO2, BPK-S Integration Ceramic, Biolox Delta-CeramTec GmbH, Plochingen, Germany). Eighty patients (40 in each group) received either a completely metal-free ceramic system (matrix of aluminum and zirconium oxide) or an anatomically identical metallic knee system made of a cobalt-chromium alloy. Clinical assessment was performed preoperatively, and during follow-up at 3 and 12 months, using the Knee Society Score, Oxford Knee Score, and EQ-5D-VAS. For radiological evaluation, standard preoperative and postoperative standardized radiographs were taken at the given follow-up visits. RESULTS: The postoperative clinical scores improved significantly at the 3- and 12-month follow-ups, but did not differ statistically between the two groups. The radiologically evaluated mean postoperative mechanical and anatomical axes showed proper alignment within both groups at all times. No revision surgery had to be performed, and no complications or loosening were recorded whatsoever. CONCLUSIONS: To our knowledge, this is the first study comparing a total ceramic metal-free knee system with a geometrically identical metallic TKA (total knee arthroplasty). Longer follow-ups will be required to demonstrate the overall efficiency of this TKR and perhaps to expand its medical indication. PMID- 29471558 TI - Indication, Technique and Long-term Results after Shoulder Arthrodesis Performed with Plate Fixation. AB - AIM: Arthrodesis of the shoulder joint is a radical event, so it is difficult to explain its significance to patients. It has been the last resort in hopeless cases. Knowledge of long-term results and evaluation of advantages and disadvantages seems to be helpful in this regard. METHODS: Eleven patients with mean age of 45 (31 - 58) years were operated between 2000 and 2013. All patients could be included in the investigation (FU mean 8.5 [3 - 16] years; 8 male and 3 female; right 9, left 2). Patients had the following indications: persistent instability 5 (2 with epilepsy), rotator cuff rupture 2 (1* after combined latissimus dorsi and teres major transfer), brachial plexus injury/defect 2, locked dislocation 1 and posttraumatic arthropathy 1. Fixation with DC plate (pre bent to 110 degrees ) was used in all cases; with special focus on placing at least one screw in the scapular neck. The targeted arthrodesis position was abduction 30 degrees , forward flexion 30 degrees , and internal rotation 30 degrees . RESULTS: Active abduction improved from 12 to 63 degrees , forward flexion from 21 to 79 degrees and internal rotation from 10 to 47 degrees (mean values). In the resting position with hanging arm aside, mean abduction was 3 degrees and forward flexion 8 degrees . Nine of 11 patients had considerable relief of pain, from 8.3 to 2.4 points VAS. Five patients rated the outcome as excellent, 3 as good and 1 as satisfactory. Nine patients would repeat the procedure. In summary, an Oxford Shoulder Score of 31.6 points was achieved, and SSV of 58%. Bony fusion was achieved in all cases, 3 - 4 months p. o. in mean. There were no important neurological or angiological complications. CONCLUSIONS: Plate arthrodesis in the technique used achieves high fusion and a low complication rate. Relief of pain and functional improvement are astonishing. Analysis of our results indicates that correction of the positions mentioned above is necessary: i. o. arthrodesis position for abduction 25 degrees (by means of pre-bending plate of 105 degrees ), forward flexion 20 degrees and internal rotation 30 degrees are suggested. PMID- 29471559 TI - [Suturing an Acute ACL Lesion with Dynamic Intraligamentary Stabilisation]. AB - BACKGROUND: The established surgical technique for lesion of the anterior cruciate ligament (ACL) is reconstruction with an autologous tendon. However, patients after ACL-replacement have increased osteoarthritis rates. Possible explanations are persistent knee instability and the loss of the ACL's proprioceptive function. Therefore, surgeons have developed an alternative treatment to preserve the ACL by readapting femoral ACL lesions by temporary protective dynamic intraligamentary stabilisation (DIS). INDICATION: The indication includes acute (< 21 days old) ACL injuries of young patients who are active in sport. The rupture should be located in the proximal third of the ACL with a side-to-side interval of more than 5 mm in the antero-posterior tibial translation. METHODS: In this video, a 22-year-old patient with an ACL lesion was operated three weeks after injury. CONCLUSION: Readapting femoral ACL lesions by DIS is an adequate technique to preserve the ACL and to restore knee stability. PMID- 29471560 TI - ? AB - Bone sarcomas are extremely rare representing approximately 0.2% among all cancer types. Due to the rarity of these tumors both the patients and the physicians can overlook or misinterpret the first often unspecific symptoms of these tumors (pain, limping and swelling). Therefore, radiographic examination (X-ray and/or MRI) of the involved region in case of inexplicable symptoms is strongly recommended. The most common primary malignant bone tumor entity is osteosarcoma, followed by chondrosarcoma and Ewing sarcoma. Osteosarcomas and Ewing sarcomas occur predominantly in children, adolescents and young adults, while chondrosarcomas primarily affect older patients. Most of the tumors are located in the extremities and the pelvis and in about 90% of cases the surgical treatment can be performed by means of a limb-sparing wide resection. An endoprosthetic or biological reconstruction of the resulting defect, depending on several patient- und tumor-related factors, usually is necessary. Apart from the surgical treatment, patients with osteosarcoma and Ewing sarcoma require a pre- and postoperative chemotherapy, while Ewing sarcoma patients often undergo radiation therapy as well - in some cases as the only local therapy option. Regular follow-up examinations are required after the completion of treatment for the early detection and management of local and/or systemic recurrences. Diagnosis and therapy of these rare tumors must be obtained by an interdisciplinary approach for optimal patient care (i.e. oncologist, radiologists, pathologists, orthopaedic surgeons, radiotherapists). Without an interdisciplinary proceeding the risk of mistakes increases significantly, which can have grave consequences on the patients' prognosis and functional outcome. Therefore, the centralized treatment of these patients in specialized sarcoma centres is recommended. PMID- 29471561 TI - Nonalcoholic Fatty Liver Disease in Children. AB - Nonalcoholic steatohepatitis, a progressive form of nonalcoholic fatty liver disease (NAFLD), is one of the most common hepatic diseases in children who present with particular risk factors including obesity, sedentary lifestyle, and/or a predisposing genetic background. The worldwide prevalence of NAFLD in children is a worrying phenomenon because this disease is closely associated with the development of both cirrhosis and cardiometabolic syndrome in adulthood. To date, the etiopathogenesis of primary NAFLD in children is unknown. Understanding the pathogenetic mechanisms provides the basis to characterize early predictors of the disease and noninvasive diagnostic tools and to design novel specific treatments and possible management strategies. Despite a few clinical trials on the use of antioxidants combined with lifestyle intervention for NAFLD, no treatment exists for children with NAFLD. In this review, the authors provide an overview of current concepts in epidemiology, histological features, etiopathogenesis, diagnosis, and treatment of NAFLD in pediatric population. PMID- 29471562 TI - Can Elastography Differentiate Isolated Fatty Liver from Nonalcoholic Steatohepatitis? AB - Ultrasound and magnetic resonance (MR)-based elastography have demonstrated excellent performance for noninvasive staging of fibrosis in patients with nonalcoholic fatty liver disease (NAFLD); however, their ability to differentiate isolated fatty liver from nonalcoholic steatohepatitis (NASH) is unclear. In this review, the authors provide background on elastography and review the ability of elastography to discriminate between isolated steatosis and NASH. Studies with available data on the diagnosis of NASH histology are limited to vibration controlled transient elastography and MR elastography. A wide range of optimal cutoffs for the diagnosis of NASH are reported and likely depend on the prevalence of advanced fibrosis in the study population. MR elastography has good performance characteristics for identifying patients with any fibrosis who are at greatest risk of disease-related morbidity. Currently, neither modality can reliably discriminate NASH from simple steatosis. Novel multiparametric MR imaging and elastography are emerging and may help detect presence of NASH in the future. PMID- 29471563 TI - Hepatic Damage by Natural Remedies. AB - The rising burden of herbal and dietary supplement hepatotoxicity (HILI) is a growing concern in Western countries. The estimated incidence of HILI in well designed prospective studies ranges from less than 1 to 3 individuals per 100,000 inhabitants/year. Herbal hepatotoxicity has a particular signature encompassing female predominance, hepatocellular type of damage with markedly elevated transaminases on presentation, more common unintentional rechallenge, and a greater risk of death/liver transplantation. Herbal hepatotoxicity recognition is particularly challenging for hepatologists because of the often hidden herbal consumption, difficulties in identifying the causative herbal component, and the possibility of contamination, adulteration, and misidentification, which preclude a proper adjudication and lead to inaccurate reporting of cases in scientific journals. Collaborative efforts to retrieve detailed phenotypic data and biological samples of patients with HILI would facilitate genomic and other molecular approaches for a better understanding of host risk factors and, hopefully, for biomarker identification. PMID- 29471564 TI - Genetic and Epigenetic Heterogeneity in Normal Liver Homeostasis and Its Implications for Liver Disease and Hepatocellular Cancer. AB - Hepatocellular carcinoma (HCC) is the most prevalent primary tumor of the liver, and is steadily becoming one of the most lethal cancers worldwide. Liver resection, which is the recommended procedure for early localized HCC, results in frequent recurrence (50-70%), while the standard of care for late-stage HCC, multikinase inhibitors, only improves survival by a few months. The lack of success for these treatment modalities is attributable, at least in part, to marked phenotypic heterogeneity within the tumor. Intratumoral heterogeneity (ITH) has emerged as a defining characteristic of human tumors, with individual cancer cells displaying distinct differences in properties including growth rate, metastatic capacity, and response to treatment. This heterogeneity, which is unlikely to be captured from a biopsy, impacts outcome because a single treatment targeting one cancer-specific pathway would spare tumor cells having distinct characteristics. Development of effective biomarkers remains a major challenge for similar reasons. Understanding, interpreting, and circumventing the impact of ITH is therefore paramount for developing reliable biomarkers and designing effective individualized treatment strategies for HCC. PMID- 29471565 TI - Fibrolamellar Carcinoma: Recent Advances and Unresolved Questions on the Molecular Mechanisms. AB - Fibrolamellar hepatocellular carcinoma (FLC) is a rare form of primary liver cancer that affects adolescents and young adults without underlying liver disease. Surgery remains the mainstay of therapy; however, most patients are either not surgical candidates or suffer from recurrence. There is no approved systemic therapy and the overall survival remains poor. Historically classified as a subtype of hepatocellular carcinoma (HCC), FLC has a unique clinical, histological, and molecular presentation. At the genomic level, FLC contains a single 400kB deletion in chromosome 19, leading to a functional DNAJB1-PRKACA fusion protein. In this review, we detail the recent advances in our understanding of the molecular underpinnings of FLC and outline the current knowledge gaps. PMID- 29471566 TI - Mucosal-Associated Invariant T Cells in Chronic Inflammatory Liver Disease. AB - The broadening field of microbiome research has led to a substantial reappraisal of the gut-liver axis and its role in chronic liver disease. The liver is a central immunologic organ that is continuously exposed to food and microbial derived antigens from the gastrointestinal tract. Mucosal-associated invariant T (MAIT) cells are enriched in the human liver and can be activated by inflammatory cytokines and microbial antigens. In chronic inflammatory liver disease, MAIT cells are depleted suggesting an impaired MAIT cell-dependent protection against bacterial infections. PMID- 29471567 TI - Targeting Hepatitis D. AB - New therapeutic strategies to treat chronic hepatitis D are directed to deprive the hepatitis D virus (HDV) of functions necessary to complete its life cycle that are provided by the hepatitis B virus (HBV) and by the host. Current options are (1) the block by the synthetic peptide Myrcludex B of HBV surface antigen (HBsAg) entry into cells through the inhibition of the sodium taurocholate cotransporting receptor; (2) the inhibition with lonafarnib of the farnesylation of the large HD antigen, required for virion assembly; (3) the presumed reduction by the nucleic acid polymer REP 2139 of the release of the HBsAg and subviral HBV particles necessary for HD virion morphogenesis. Lonafarnib and Myrcludex in monotherapy reduced serum HDV-RNA but did not reduce the HBsAg and HD viremia rebounded after therapy; they may provide additional efficacy to pegylated interferon alpha (Peg IFN-alpha) therapy. Treatment with REP-2139 in combination with Peg IFN-alpha induced a sustained clearance both of the HDV-RNA and HBsAg in 5 of 12 patients, providing the best interim results so far obtained in the therapy of chronic hepatitis D. PMID- 29471569 TI - Does Transjugular Intrahepatic Portosystemic Shunt Stent Differentially Improve Survival in a Subset of Cirrhotic Patients? AB - Does transjugular intrahepatic portosystemic shunt stent (TIPS) improve survival in a subgroup of patients? Yes. TIPS nearly halves portal pressure and increases the effective blood volume. In cases of acute variceal hemorrhage and with a high risk of treatment failure, defined as either hepatic venous pressure gradient higher than 20 mm Hg, Child B with active bleeding at the endoscopy, or Child C with less than 14 points, early or preemptive placement of TIPS (within 72 hours) improves survival. Also, in suitable patients with intractable or refractory ascites, TIPS improves survival if placed early in the course of treatment. While TIPS does not improve survival in other situations, it improves disease management, especially in patients without TIPS contraindications but with refractory bleeding, early rebleeding, portal vein thrombosis, and hepatorenal syndrome. Experience gained at the centers and follow-up of TIPS patients are key features that improve outcome. Important factors for selection and follow-up include cardiac function, inflammation, sarcopenia, age, and early evaluation for liver transplantation. PMID- 29471568 TI - The Receptor Interacting Protein Kinases in the Liver. AB - The receptor interacting serine/threonine kinase1 and 3 (RIPK1, RIPK3) are regulators of cell death and survival. RIPK1 kinase activity is required for necroptosis and apoptosis, while its scaffolding function is necessary for survival. Although both proteins can mediate apoptosis, RIPK1 and RIPK3 are most well-known for their role in the execution of necroptosis via the mixed lineage domain like pseudokinase. Necroptosis is a caspase-independent regulated cell death program which was first described in cultured cells with unknown physiologic relevance in the liver. Many recent reports have suggested that RIPK1 and/or RIPK3 participate in liver disease pathogenesis and cell death. Notably, both proteins have been shown to mediate inflammation independent of cell death. Whether necroptosis occurs in hepatocytes, and how it is executed in the presence of an intact caspase machinery is controversial. In spite of this controversy, it is evident that RIPK1 and RIPK3 participate in many experimental liver disease models. Therefore, in addition to cell death signaling, their necroptosis independent role warrants further examination. PMID- 29471570 TI - [Differentiated Drug Therapy - Especially Important in Old Age]. PMID- 29471571 TI - [57-Year-Old Women: Skin Alteration on Belly]. PMID- 29471572 TI - [Cardiovascular Medication in Elderly Patients]. AB - Elderly people show increased probability to develop atherosclerotic diseases; in consequence heart failure - most often following coronary heart disease - as well as atrial fibrillation is more common. Following guidelines may lead to polypharmacy, i. e. use of more than 5 drugs daily. Thus, drug interactions as well as side effects become more likely; especially in elderly patients reduced kidney function has to be taken into account. Only drugs which have shown to prolong life or to reduce symptoms in controlled clinical trials should be used. There is little evidence to use low dose aspirin or lipid lowering agents in primary prevention especially in elderly. ACE inhibitors, beta blocker and MRA are effective to improve symptoms and outcome in HFrEF but not in HFmEF or HFpEF. This also holds true for the elderly. Withdrawal of long term diuretic treatment in the elderly patients may lead to symptoms of heart failure or increase in blood pressure to hypertensive values often. In coronary heart disease beta blocker may be used to control symptoms as well as to reduce the need for coronary intervention following 1 year after myocardial infarction. Because the risk of stroke increases with age more than the risk of bleeding, the absolute benefit of oral anticoagulation in atrial fibrillation patients is highest in the elderly. NOAK appear to be safer and at least as efficacious as warfarin. PMID- 29471573 TI - [Which drugs in Hemato-Oncology are Unnecessary or Inappropriate for Use in the Elderly?] AB - There is a vast amount of drugs and therapeutic regimens available today to treat hemato-oncological diseases. This offers new opportunities to close known gaps of undertreatment in older individuals with cancer, but also increases the risk of overtreatment in this patient group. Currently available criteria (drug listings) for potentially inadequate prescribing in the elderly are not matured enough to serve hemato-oncologists as a guidance when trying to identify unnecessary or inappropriate cancer medication in routine clinical practice. In some clinical situations (e. g., decision-making for adjuvant treatment), online tools that allow for a rough prediction of remaining life expectancy (without or with cancer) as well as chemotherapy toxicity could help to detect risks of overtreatment in individual patients, however. Avoiding chemotherapy in distinct therapeutic situations has become possible for some hematological and solid tumors due to a growing number of novel targeted (i. e. non-cytostatic) drugs. This development appears of particular benefit for elderly patients. The present review discusses tools that generally could support the identification of overtreatment in older patients with such diseases. Drug examples are presented for some common hemato-oncological entities. PMID- 29471574 TI - [Type 2 Diabetes Diabetes in Older Adults: Example for Patient-Centered Drug Therapy]. AB - Diabetes in older adults has a high prevalence and is frequently associated with comorbidities of the cardiovascular system, dysfunction of cognition as well as depression and impaired mobility or increased frailty. Furthermore, impaired renal function, heart failure, risk for hypoglycemia and polypharmacy has to be considered in the decision about the diabetes treatment strategy. The goal of blood glucose management is driven by patient relevant issues and patient self esteem, quality of life defined by the patient, preservation of physical and social mobility rather than potential long-term effects on reduction of cardio- and microvascular events in the future, which is limited by patient-inherent reduced life expectancy of the aged individual. Therefore, long-term diabetes medication should avoid hypoglycemia and prevent acute hyperglycemia or short term complications on morbidity and clinical course of geriatric syndromes associated with regular blood glucose levels above 200 mg/dl (11.1 mmol/l). The therapy should be safe, easy to handle for the patient and possibly affect co morbidities positively. However, there are limited data available about efficacy, safety and pharmacokinetics of drugs in patients over 75 years of age or older. Since more than 5 % of the population in Germany is older than 80 years means that more than 1 million of these individuals suffer from diabetes. It is time to ask for data in these elderly subpopulations by policy makers in health care. PMID- 29471575 TI - [Breast Cancer: Diagnostics and Therapy - the Most Important Facts for Internists]. AB - LEARNING OBJECTIVES: After reviewing this article, the participant should be able to: 1. Understand the epidemiology of breast cancer, its incidence and impact. 2. Appreciate the importance of early diagnosis and treatment. 3. Understand the concept of comprehensive breast cancer management and its multidisciplinarity. 4. Be knowledgeable about the entire process required to manage breast cancer, since the early diagnosis until the management of non breast related conditions derived from the treatment. 5. Position their specialty and knowledge in the process and know clearly their role and involvement in the management of the patients with breast cancer. SUMMARY: Breast carcinoma accounts for the majority of the malignant diseases in women. In Germany has an estimated incidence of 70 000 new cases per year, which is 30 % of all the malignancies in women, predominantly between 45 and 83 years old, although it can affect as well younger women and men, the latter, in a very low rate. It is accountable for 17.4 % mortality in the country.The high frequency and impact of the mammary carcinoma had lead to the establishment and standardization of screening programs, encompassing self examination, early and regular consultation, sonography and mammography, aimed to the early detection not only of primary disease but also in recurrent or relapsing disease, and continued following up after treatment. Several treatment strategies and tools have been developed and are being chosen in accordance to the histology and biology of the tumor, the patient condition, the social and familiar status, with the increase of conservation of the mammary gland either by adjuvant or neoadjuvant therapies, with radiotherapy or by breast conserving surgery, improving therefore the quality of living without compromising the disease free survival. Next step in the process is the follow up, intended to maintain the patients the healthiest possible, not only from the malignancy but also minimizing the effects of the treatment strategies, incorporating lifestyle improving measures e.g. sports and nutrition, and alternative medicine resources like acupuncture, hence improving the disease free survival rate, the overall survival and diminishing the disease related impact yet personal, familiar, social and economical.The aim of this CME is to give a thorough review of this multifactorial entity, helping the healthcare professional understand the scientific aspects of it and, through comprehensive reading, provide a clear understanding of their role and degree of involvement in the breast cancer management process.

AB - In Germany, the "Dietary Schedule for the 1st year of life" and the "Optimised Mixed Diet" for children and adolescents serve as scientifically based and generally applicable dietary concepts throughout the period of growth and development. Vegetarian diets as the lacto-ovo-vegetarian diet (exclusion of meat, fish) and the vegan diet (exclusion of all food groups of animal origin) need to be evaluated for their potential to safely meet the high and specific requirements for growth and development. In this regard, high-quality studies are needed. In individuals on lacto-ovo-vegetarian diets, the safe supply with critical nutrients should be checked by thorough dietary history, possibly additional laboratory tests in risk situations like pregnancy, infancy and toddlerhood. Children on pure vegan diet need ongoing elaborate dietary strategies and continuous supplementation at any age, similar to nutritional management in children with metabolic disorders. A vegan diet is disadvised during all periods with intense growth and development. PMID- 29471577 TI - [Advances in Cardiology - 40 Years Influenced by Erland Erdmann].

PMID- 29471580 TI - Prevalence of early and late prematurity is similar among pediatric type 1 diabetes patients and the general population. AB - BACKGROUND: The incidence of type 1 diabetes mellitus (T1DM) has increased in recent decades, as has the incidence of preterm births (<37 weeks). We aimed to evaluate and compare the prevalence of prematurity and early prematurity (<34 weeks) and birth season variability among T1DM and non-T1DM children. METHODS: A nationwide cross-sectional study was conducted, with linkage of data from 13 paediatric diabetes centers and Israeli National Registries, including T1DM patients and general non-T1DM population, born during 2000 to 2013. Gathered data included ethnicity, gender, birth week, weight, and season. The prevalence of prematurity and birth season were compared with the general population birth registry using Pearson Chi-square test. RESULTS: The study population included 1452 T1DM patients, 52.7% males, and 2 138 668 subjects in the general non-T1DM population, 51.2% males. The prevalence of late and early prematurity was similar between groups (6.1% and 2.2% in the T1DM group vs 5.6% and 2.0% in the general non-T1DM group, P = 0.25 and P = 0.38, respectively). OR for prematurity among T1DM patients was 1.15 (0.95-1.39), P = 0.16. No difference in birth season was demonstrated between preterm and term, in T1DM and general non-T1DM populations. Ethiopian descent was more prevalent among T1DM patients compared with the non T1DM population, in both term and preterm born. CONCLUSIONS: This is the largest population-based study, and the first in the Middle East geographical area, indicating that prematurity, including early prematurity, is not associated with T1DM during childhood. The study was registered at https://clinicaltrials.gov/: NCT02929953.

Cox regression was performed on Heberden's node presence, total number, location, and symmetry (using 2 symmetry index models) obtained at baseline physical examination as well as self-report of Heberden's node presence for evaluation of association with radiographic knee OA incidence (development of a Kellgren/Lawrence grade of >=2) and progression (worsening in the medial joint space narrowing score of >=1). Covariate adjustments relevant to OA outcomes were performed. RESULTS: The presence of Heberden's nodes (in 64% of the subjects) at baseline physical examinations, but not subjective self-report of Heberden's nodes, was associated with radiographic knee OA incidence (hazard ratio [HR] 1.19 and 95% confidence interval [95% CI] 1.001-1.402 [approached statistical significance]). Each additional Heberden's node found on physical examination was associated with knee OA incidence (HR 1.03 [95% CI 1.000-1.054] [approached statistical significance]) and progression (HR 1.04 [95% CI 1.016-1.063]). Knee OA incidence and progression were associated with Heberden's nodes located on the third digit (HR 1.26 [95% CI 1.068-1.487] and 1.18 [95% CI 1.019-1.361], respectively) and first digit (HR 1.186 [95% CI 0.992-1.418] [approached statistical significance] and HR 1.26 [95% CI 1.084-1.453], respectively). Heberden's node symmetry was associated with knee OA incidence (model 1 HR 1.09 [95% CI 0.997-1.185] [approached statistical significance]) and progression (model 2 HR 1.13 [95% CI 1.035-1.234]). CONCLUSION: The number of Heberden's nodes, their locations, and symmetry were associated with knee OA incidence and progression over 8 years. PMID- 29471582 TI - Diabetic dyslipidaemia is associated with alterations in eNOS, caveolin-1, and endothelial dysfunction in streptozotocin treated rats. AB - BACKGROUND: Diabetes is a complex progressive disease characterized by chronic hyperglycaemia and dyslipidaemia associated with endothelial dysfunction. Oxidized LDL (Ox-LDL) is elevated in diabetes and may contribute to endothelial dysfunction. The aim of this study was to relate the serum levels of Ox-LDL with endothelial dysfunction in streptozotocin (STZ)-diabetic rats and to further explore the changes in endothelial nitric oxide synthase (eNOS) and caveolin-1 (CAV-1) expression in primary aortic endothelial cells. METHODS: Diabetes was induced with a single intraperitoneal injection of STZ in male Wistar rats. During the hyperglycaemic diabetes state serum lipid markers, aortic relaxation and aortic endothelial cell eNOS and CAV-1 protein expressions were measured. RESULTS: Elevated serum Ox-LDL (STZ 1486 +/- 78.1 pg/mL vs control 732.6 +/- 160.6 pg/mL, P < .05) was associated with hyperglycaemia (STZ 29 +/- 0.9 mmol/L vs control: 7.2 +/- 0.2 mmol/L, P < .001) and hypertriglyceridaemia (STZ 9.0 +/- 1.5 mmol/L vs control: 3.0 +/- 0.3 mmol/L, P < .01) in diabetic rats. A significant reduction was observed in STZ-diabetic aortic endothelial cell eNOS and CAV-1 of 40% and 30%, respectively, accompanied by a compromised STZ-diabetic carbachol-induced vasodilation (STZ 29.6 +/- 9.3% vs control 77.2 +/- 2.5%, P < .001). CONCLUSIONS: The elevated serum Ox-LDL in hyperglycaemic STZ-diabetic rats may contribute to diabetic endothelial dysfunction, possibly through downregulation of endothelial CAV-1 and eNOS.

This National Partnership for Maternity Safety bundle, as with other bundles, is organized into four domains: Readiness, Recognition and Prevention, Response, and Reporting and Systems Learning. Bundle components may be adapted to individual facilities, but standardization within an institution is advised. Evidence-based resources and recommendations are provided to assist implementation. PMID- 29471584 TI - Vasudhaiva Kutumbakam: The World Is One Family. PMID- 29471585 TI - Ripply3 is required for the maintenance of epithelial sheets in the morphogenesis of pharyngeal pouches. AB - During tissue development, the morphogenesis of epithelial sheets is regulated by many factors, including mechanical force, although the underlying mechanisms remain largely unknown. In the pharyngeal region of the vertebrate embryo, endodermal epithelium is reiteratively folded outward to form pharyngeal pouches, making partitions between the pharyngeal arches. Ripply3, encoding a member of the Ripply family of adaptor proteins, is required for the pouch formation posterior to the 2nd pharyngeal pouch. In this study, we found that the expression of mouse Ripply3 was specifically activated in accordance with the bending of the endodermal epithelium during the pouch formation. In Ripply3 deficient embryos, a continuous monolayer of the endodermal epithelium was not maintained posterior to the 2nd pharyngeal pouch. Corresponding to the endodermal region of the deformed epithelium, the activated form of Integrin beta1, which was localized at the basal side of the epithelial cells in the wild-type embryos, was not persistently observed in the mutants. On the other hand, cell proliferation and apoptotic cell death in the endoderm were not obviously affected by the Ripply3 deficiency. Significantly, Ripply3 expressed in cultured cells was found to be preferentially accumulated in the focal adhesions, which are Integrin-mediated adhesive contact sites transmitting mechanical force between the extracellular matrix and attached cells. Furthermore, Ripply3 promoted the maturation of focal adhesions in these cells. Thus, Ripply3 appears to have been activated to enhance the connection between the extracellular matrix and endodermal epithelial cells, as a mechanism to resist the mechanical stress generated during the bending of the epithelial sheets.

PMID- 29471587 TI - Managing unsolicited findings in genomics: A qualitative interview study with cancer patients. AB - OBJECTIVE: Next-generation sequencing (NGS) is increasingly being employed in the context of personalized cancer treatment. Anticipating unsolicited findings that may arise during a NGS procedure is a key consideration; however, little is known about cancer patients' intentions, needs, and preferences concerning the return of unsolicited findings. METHODS: A qualitative design using individual semi structured interviews with 24 cancer patients was utilized to explore patients' decisions on whether to receive unsolicited findings from NGS. These interviews were subsequently analyzed using the constant comparative method to develop codes and themes. RESULTS: We identified 4 interrelated themes that emerged in the context of the return of unsolicited findings. First, we describe how cancer patients expressed a strong need to control their lives. Second, we show the importance of family dynamics. Third, the NGS procedure regarding unsolicited findings is perceived as cognitively complex, and fourth, the procedure is also considered emotionally complex. CONCLUSIONS: The results of our study contribute to a better understanding of what cancer patients consider important and what may motivate and influence them when making decisions on the disclosure of unsolicited findings following NGS. We show how Joel Feinberg's classification of autonomy may help clinicians to better understand cancer patients' desire for autonomous decision making while also acknowledging the emotional and cognitive difficulties regarding the disclosure of unsolicited findings. These insights could be helpful for clinicians to guide patients through this complex process. PMID- 29471588 TI - Brief Report: Attenuated Effectiveness of Tumor Necrosis Factor Inhibitors for Anti-Human T Lymphotropic Virus Type I Antibody-Positive Rheumatoid Arthritis. AB - OBJECTIVE: To evaluate the effectiveness of tumor necrosis factor (TNF) inhibitors for the treatment of human T lymphotropic virus type I (HTLV-I) positive patients with rheumatoid arthritis (RA) in an area endemic for HTLV-I infection. METHODS: We conducted an observational study of 585 RA patients in whom TNF inhibitors were newly introduced as a first biologic disease-modifying antirheumatic drug in an area in southwestern Japan that is endemic for HTLV-I infection. RESULTS: Fifty patients (8.5%) were anti-HTLV-I antibody-positive. The ages of the patients in this group were significantly higher at entry compared with the ages of patients who were anti-HTLV-I antibody-negative (n = 535). The median Disease Activity Score in 28 joints using the erythrocyte sedimentation rate (DAS28-ESR) was 5.21. Among the total group of patients, 82% were anti citrullinated protein antibody (ACPA)-positive. The persistence rate of TNF inhibitors at 24 weeks was 89%. The median DAS28-ESR was significantly decreased at 24 weeks in each group. The European League Against Rheumatism (EULAR) response rate was significantly better in the anti-HTLV-I antibody-negative patients (P = 0.0277). Multiple regression analysis demonstrated that anti-HTLV-I antibody status was significantly associated with the EULAR response rate and change in the DAS28-ESR and was prominent especially in the ACPA-negative subjects. No patients developed adult T cell leukemia/lymphoma (ATL) or HTLV-I associated myelopathy (HAM) during the 24-week treatment period. CONCLUSION: The efficacy of TNF inhibitors may be attenuated in anti-HTLV-I antibody-positive patients with RA. ATL and HAM did not develop when TNF inhibitors were used for 24 weeks, but the long-term risk is not known. PMID- 29471589 TI - Looking back and looking forward. PMID- 29471590 TI - Consumer use and response to online third-party raw DNA interpretation services. AB - BACKGROUND: With the availability of raw DNA generated from direct-to-consumer (DTC) testing companies, there has been a proliferation of third-party online services that are available to interpret the raw data for both genealogy and/or health purposes. This study examines the current landscape and downstream clinical implications of consumer use of third-party services. METHODS: Study participants were recruited online from social media platforms. A total of 321 survey respondents reported using third-party services for raw DNA interpretation. RESULTS: Participants were highly motivated to explore raw DNA for ancestral information (67%), individual health implications (62%), or both (40%). Participants primarily used one of seven companies to interpret raw DNA; 73% used more than one. Company choice was driven by the type of results offered (51%), price (45%), and online reviews (31%). Approximately 30% of participants shared results with a medical provider and 21% shared with more than one. Outcomes of sharing ranged from disinterest/discounting of the information to diagnosis of genetic conditions. Participants were highly satisfied with their decision to analyze raw DNA (M = 4.54/5), yet challenges in understanding interpretation results were reported irrespective of satisfaction ratings. CONCLUSION: Consumers face challenges in understanding the results and may seek out clinical assistance in interpreting their raw DNA results.

PMID- 29471591 TI - Improvement of life quality measured by Lansky Score after enzymatic replacement therapy in children with Gaucher disease type 1. AB - BACKGROUND: Gaucher disease type 1 (GD1, OMIM# 230800), is a condition with high impact in patient's quality of life (QoL). We report the improvement in QoL of children with GD1 measured by Lansky play-performance scale (LS) after enzymatic replacement therapy (ERT) and to describe our experience in the treatment of children with GD1. METHODS: Five children with diagnosis of GD1 received imiglucerase 60 mg/kg every two weeks. LS, hepatomegaly, splenomegaly, hemoglobin, platelets, and growth rate were measured every 6 months after beginning ERT for 30 months. RESULTS: After ERT, LS increased significantly from 28 +/- 16.48 points before ERT to 70 +/- 10 (P = 0.0046) and 95 +/- 10 (P = 0.0022) points after 6 and 30 months of ERT, respectively; hemoglobin and platelets changed significantly from 9.28 +/- 0.61 to 12.40 +/- 0.85 (P = 0.0198) and from 71.50 +/- 14.89 to 205.00 +/- 65.34 (P = 0.0428) after 30 months of ERT, respectively. All patients demonstrated decreased hepatic and splenic size with mean reductions of 66% and 80% at 30 months of treatment and the USG longitudinal axis was reduced in both liver and spleen after ERT. CONCLUSION: The use of ERT with imiglucerase 60 mg/kg every two weeks has substantial benefits and significantly improves QoL, assessed with Lansky Score, of the five children with GD1 studied. PMID- 29471593 TI - Clinical Evolution in Patients With New-Onset Inflammatory Back Pain: A Population-Based Cohort Study. AB - OBJECTIVE: Inflammatory back pain (IBP) is often an early manifestation of spondyloarthritis (SpA), but the prognosis of patients with incident IBP is unknown. This study was undertaken to investigate long-term outcomes in patients with IBP, and predictors of progression to SpA, in a population-based cohort. METHODS: We conducted a retrospective, longitudinal study using the Rochester Epidemiology Project, a longstanding population-based cohort of residents of Olmsted County, MN. Patients ages 16-35 years with clinical visits for back pain from 1999 to 2003 were identified, and we screened these patients for the presence of new-onset IBP and performed medical record reviews to collect data on clinical, laboratory, and imaging features of SpA. Outcomes in these patients were followed up until July 2016. We used survival analysis for competing risks to examine progression to either SpA, a non-SpA diagnosis, or resolution of back pain. Recursive partitioning was used to identify predictors of progression to SpA. RESULTS: Among 5,304 patients with back pain, we identified 124 patients with new-onset IBP. After a median follow-up of 13.2 years, IBP had progressed to SpA in 39 patients, 15 patients developed a non-SpA diagnosis, and 58 patients had resolution of IBP. At 10 years, the probability of having SpA was 30%, while the probability of resolution of IBP was 43%. The most important predictors for progression to SpA were uveitis, male sex, and family history of SpA. CONCLUSION: In a minority of patients, new-onset IBP progresses to SpA, while IBP resolves in many. That IBP often resolves may explain the difference between the prevalence of IBP (3-6%) and the prevalence of SpA (0.4-1.3%).

PMID- 29471595 TI - Procollagen-III peptide identifies adipose tissue-associated inflammation in type 2 diabetes with or without nonalcoholic liver disease. AB - BACKGROUND: Procollagen-III peptide (PIIINP) is a marker of fibrosis associated with increased cardiometabolic risk and progression of chronic liver diseases such as nonalcoholic fatty liver disease (NAFLD) and steatohepatitis; its association with type 2 diabetes mellitus (T2DM) has not been elucidated yet. The aim of this study was to investigate the relationship among circulating PIIINP levels, metabolic traits, and body fat distribution in subjects with T2DM with or without NAFLD. METHODS: Data from 62 T2DM subjects recruited in our diabetes outpatient clinics at Sapienza University of Rome, Italy, were analysed. Participants underwent metabolic and inflammatory profiling (CRP, TNFalpha, IL-6, IL-8, WISP1, and adiponectin) and magnetic resonance imaging for diagnosing NAFLD on the basis of hepatic fat fraction (>=5.5%) and quantifying visceral and subcutaneous adipose tissue (AT) areas. Serum PIIINP was measured by human-PIIINP ELISA kits. RESULTS: Higher PIIINP levels correlated with greater BMI and visceral AT area and were associated with systemic signatures of AT-associated inflammation-ie, higher WISP-1, IL-8, and lower adiponectin levels; conversely, PIIINP did not differ significantly between T2DM patients with or without NAFLD and were not associated with hepatic fat fraction, Fatty Liver Index, FIB-4, or transaminases. CONCLUSIONS: Elevated circulating PIIINP levels specifically identify T2DM individuals with AT expansion and systemic proinflammatory profile suggestive for AT dysfunction; our results point toward a new role of PIIINP as a marker of fibroinflammation in dysmetabolic conditions, likely related to AT expansion. PMID- 29471596 TI - [Clinical Benefits of Transurethral Resection Under Narrow Band Imaging for Non Muscle Invasive Bladder Cancer]. AB - The aim of this study was to reveal the clinical benefits of transurethral resection (TUR) under narrow band imaging (NBI-TUR) for non-muscle-invasive bladder cancer (NMIBC) compared with conventional white light imaging TUR (WLI TUR). The subjects were 172 patients with NMIBC who were followed for more than 1 year after undergoing TUR with no additional postoperative treatment. In the WLI TUR group (n=101), lesions that were detected as positive after systematic intravesical observation under WLI were resected completely under WLI. In the NBI TUR group (n=71), similar observations under WLI were followed by systematic intravesical observation under NBI. After multiple site biopsy under NBI, TUR was performed for all lesions that were detected as positive under NBI. The sensitivity was calculated based on the results of cystoscopy and pathology of multiple site biopsy samples under WLI and NBI in the NBITUR group. The tumor recurrence rate was analyzed in both groups. Background factors did not differ significantly between the two groups, except for the observation period (63.3 months in the WLI-TUR group vs 42.0 months in the NBI-TUR group, p<0.01). The procedure under NBI had significantly higher sensitivity (94.6% vs 75.0%, p<0.01) compared with that under WLI. The recurrence-free rate in the NBITUR group was significantly higher than that in the WLI-TUR group (p=0.013). The tumor recurrencefree rate of NBI-TUR is higher than that of conventional WLI-TUR for patients with NMIBC.

AB - The 2014 International Society of Urological Pathology (ISUP) has proposed a new grade group (GG) classification for Gleason scores (GS). The usefulness of the new GG classification was investigated with 518 prostate cancer patients who underwent androgen deprivation therapy. According to the new GG classification, Stages B-D and the new GG classification relapse-free rate for each stage were calculated using the Kaplan-Meier method. The new GG classification revealed a significant difference for the relapse-free rate only between some groups. Analysis using the Cox proportional hazards model indicated that the risk of relapse was higher in GGs 4 and 5 than in GG 1. The usefulness about the relapse free rate in androgen deprivation therapy of the 2014 ISUP new grade group classification a waits future examination. PMID- 29471598 TI - [Ureteral Cancer Developing in Retrocaval Ureter : A Case Report]. AB - Ureteral cancer in the retrocaval ureter is rare. We herein report a patient with this condition laparoscopically treated. A 69-year-old man was referred to us because of right ureteral cancer diagnosed during ureteroscopic surgery for a ureteral calculus. Histological diagnosis of the ureteroscopically biopsied material was non-invasive papillary urothelial carcinoma, low grade (G2). Computed tomography (CT) demonstrated a retrocaval ureter : a double J stent placed during ureteroscopy assisted the diagnosis. The patient underwent retroperitoneoscopic complete nephroureterectomy on the right side. Sufficient separation of the right ureter and the inferior vena cava under retroperitoneoscopic procedures facilitated en bloc extirpation of the kidney and ureter with a minimal lower abdominal incision. The surgical procedures for ureteral cancer in the retrocaval ureter, should be preoperatively considered with care.

AB - An 11-year-old boy was referred to our department with the chief complaint of acute urinary retention. He had had a history of viral enteritis a few days before the onset of dysuria. He presented with a slight fever, mild headache and weakness of the extremities. A cerebrospinal fluid examination showed the elevation of cell number (cell number : 158/3, polynuclear cells : 29/3, and mononuclear cells : 129/3). Although spinal magnetic resonance imaging (MRI) did not show abnormal findings, fluid attenuated inversion recovery (FLAIR) image of the brain MRI showed a high signal area on the cerebral cortex. Acute disseminated encephalomyelitis (ADEM) was suspected from the clinical course, the cerebrospinal fluid examination, and brain MRI findings. A urethral catheter was indwelled for urinary retention, and steroid pulse therapy was promptly started. After removal of the urethral catheter seven days after the therapy initiation, normal urination without residual urine was observed. Findings of a cerebrospinal fluid test and brain MRI also showed improvement. PMID- 29471600 TI - [Two Cases of Transperineal Urethral Resection of the Prostate].

PMID- 29471602 TI - [Evolving Therapeutic Strategies in the Inflammatory Bowel Disease]. AB - It is important to have effective therapeutic strategies and goals in clinical practice and research of inflammatory bowel disease. Conventional end points for clinical trials in Crohn's disease and ulcerative colitis have been based on composite indices, such as the Crohn's Disease Activity Index and the Mayo Clinic Score. Although these indices have been shown to reduce the intestinal injury to some extent, satisfactory results have not been obtained in improving the quality of life of patients. Recently, alternative measures of outcome and definitions of response are being developed beyond symptoms. Mucosal healing as a clinical response and treatment goal has showed better long-term outcomes. Patient reported outcomes (PROs) are emerging instrument directly created by patient to quantify symptoms. Coprimary realistic treatment 'target', comprising mucosal healing and PROs, can offer a clinically valid endpoint and can be readily applied in practice compare to existing composite indices. 'Treat-to-target' algorithm based on mucosal healing and PROs, in which therapy is progressively intensified until a specific personal treatment goal is reached, could improve quality of life of patient by reducing disease-related disability. Furthermore, histologic remission is an area of increased research focus and has the potential to guide treatment decisions in the future. PMID- 29471601 TI - [Bladder Rupture during Intravesical BCG Therapy : A Case Report]. AB - A 69-year-old man received transurethral resection (TUR) ofbladder tumor. The histopathological diagnosis was urothelial carcinoma, high grade, pT1+pTis. The surgical specimens obtained by second TUR showed no residual malignancy histopathologically. Intravesical Bacillus Calmette-Guerin (BCG) instillation therapy was initiated 2 months after the second TUR. He complained of lower abdominal pain and painful urination on the day following the second instillation of BCG. Computed tomography and cystography demonstrated rupture ofthe urinary bladder. During 2 weeks ofconservative treatment, the symptoms persisted. Then, open repair ofthe bladder was performed. Intravesical BCG therapy has been a widely accepted treatment for bladder cancer with high grade Ta and T1, and carcinoma in situ. In the present case, thinning ofthe bladder wall, delayed wound healing caused by 2 TURs, and abdominal pressure may have been the factors leading to the bladder rupture in addition to inflammation of the bladder due to BCG instillation. Although bladder rupture caused by intravesical BCG therapy has not been reported, we must be aware ofthe possibility ofthis rare condition, especially after 2 consecutive TURs. PMID- 29471603 TI - [Monitoring Disease Activity: How and When?] AB - Inflammatory bowel disease (IBD) is a chronic, idiopathic inflammatory disease of gastrointestinal tract with waxing and waning clinical course, which may lead to irreversible bowel damage and a loss of bowel function. Cumulative intestinal damage results in complications such as stricture or fistulae, and eventually a large number of IBD patients undergo surgery. Notably, even during remission period (no clinical symptoms), subclinical inflammation often persists and the disease continues to progress. Therefore, the therapeutic target of IBD has been evolving from symptomatic control to mucosal healing to prevent structural intestinal damage. To achieve therapeutic goals in IBD, it is important to optimize therapy according to disease severity and response to treatment. Therefore, monitoring disease activity is recommended throughout the disease course of IBD. Especially strategies to monitor disease beyond symptoms through endoscopy, laboratory markers, and imaging is required. PMID- 29471604 TI - [How to Optimally Use Currently Available Drugs in a Therapeutic Algorithm?] AB - Recently, the incidence and prevalence of inflammatory bowel disease (IBD) have been increasing in worldwide, especially in Asian area. IBD is a chronic and progressive disease eventually causing bowel damage. The advance in the treatment of IBD over the past several decades has been achieved with the development of biologics. Furthermore, goals for management of IBD have been evolving from symptom-based management to mucosal healing, which can reduce the surgery rate and hospitalization. To treat the patients with IBD properly, identification of risk factors of patients should be preceded. In addition, the knowledge of several drugs, which are available in current situation is essential. In this review, optimal therapeutic approach with drugs including 5-aminosalicylate, steroid, immunomodulators and anti-TNF antagonists is discussed. PMID- 29471605 TI - [Emerging Therapies: What Are Promising in the Near Future?] AB - The treatment of inflammatory bowel disease has evolved with the development of anti-TNF agents. In spite of long-term effectiveness, many patients do not respond or no longer responds to these drugs. Therefore, the development of new drugs that act on different inflammatory pathways has become necessary. Vedolizumab, a gut-specific biological agent, inhibits interaction alpha4beta7 integrin with mucosal addressin cell adhesion molecule-1 without inhibiting systemic immune responses. Long-term vedolizumab therapy in patients with Crohn's disease and ulcerative colitis was safe and effective. Additionally, vedolizumab can be used in patients already failed an anti-TNF therapy. Ustekinumab is a fully human immunoglobulin G1 kappa monoclonal antibody that blocks the p40 subunit of IL-12 and IL-23. Ustekinumab will be a clinically effective agent to use in medically-refractory Crohn's disease especially as a second line drug. Tofacitinib is an oral, small molecule that inhibits JAK1, JAK3 and in a lesser extent, JAK2. Perhaps the most attractive things of these JAK inhibitors is that they are given orally instead of parenterally. Early results showed that patients with moderately to severely active ulcerative colitis receiving tofacitinib were more likely to achieve remission at 8 weeks than those receiving placebo. However, these results have not been as robust in Crohn's disease. Much of the positioning will depend on the safety profile such as opportunistic infection and atherogenic risk. The challenges for the future are to determine the therapeutic drug monitoring-guided dose optimization, optimal timing and drug combinations to produce the most effective, and safest outcomes for IBD patients. PMID- 29471606 TI - [Clinical Approach to Abdominal Pain as Functional Origin]. AB - Abdominal pain is a common symptom that patients refer to a hospital. Organic causes should be differentiated in patients with abdominal pain and treatment should be administered in accordance with the causes. A meticulous history taking and physical examination are highly useful in making a diagnosis, and blood tests, imaging modalities, and endoscopy are useful for confirming diagnosis. However, in many cases, patients have functional disorders with no obvious abnormal findings obtained even if many diagnostic tests are performed. Patients with functional disorders usually complain the vague abdominal pain located in the center and other portions of the abdominal area. Although the most representative disease is irritable bowel syndrome, functional abdominal pain syndrome is currently researched as a new disease entity of functional abdominal pain. As various receptors related to functional abdominal pain have been discovered, drugs associated with those receptors are used to treat the disorders, and additional new drugs are vigorously developed. In addition, medical therapy with pharmacological or non-pharmacological psychiatric treatment is effective for treating functional abdominal pain. PMID- 29471607 TI - Mushroom Poisoning by Macrolepiota neomastoidea. AB - There are currently over 5,000-known species of mushrooms worldwide. Only 20-25% of mushrooms have been named, and 3% of these are poisonous. More than 95% of mushroom poisoning cases occur due to difficulties associated with the identification of mushroom species. Most of the fatal mushroom poisoning cases recorded to date have been related to the Amanita species. Until now, a case of fatal poisoning caused by Macrolepiota neomastoidea (M. neomastoidea) has not been reported in Asia. A 57-year-old male patient was admitted to the emergency room with nausea, vomiting, diarrhea, and abdominal pain. He reported ingesting wild mushrooms with his mother and sister about 2 days ago. His mother and sister were treated with only supportive care, but he was admitted to the intensive care unit and underwent liver transplantation due to acute liver failure. We are reporting a case of fatal M. neomastoidea intoxication from wild mushrooms, a rare case of mushroom poisoning.

A 46-year old man presented with upper abdominal pain. The serum amylase and lipase were elevated. Abdominal computed tomography (CT) and magnetic resonance cholangiopancreatography revealed a 1.7 cm sized mass at the pancreas body with a dilatation of the upstream pancreatic duct and mild infiltrations of peripancreatic fat. An endoscopic ultrasound-guided fine needle biopsy was performed for the pancreatic mass, but only necrotic tissue was observed on the pathologic examination. A chest and neck CT scan revealed anterior mediastinal, paratracheal, and cervical lymph node enlargement, which were indicative of metastasis. An ultrasound-guided core needle biopsy was performed for the enlarged neck lymph node, and pathologic examination revealed a metastatic poorly differentiated carcinoma. Immunohistochemical analysis showed positive staining for synaptophysin, chromogranin A, and CD 56, indicative of a neuroendocrine carcinoma.

PMID- 29471610 TI - Ototoxicity: A Challenge in Diagnosis and Treatment. AB - Ototoxicity is the pharmacological adverse reaction affecting the inner ear or auditory nerve, characterized by cochlear or vestibular dysfunction. The panorama of drug-induced hearing loss has widened over last few decades. Although ototoxic medications play an imperative role in modern medicine, they have the capacity to cause harm and lead to significant morbidity. Evidence has shown early detection of toxicity through prospective ototoxicity monitoring allows for consideration of treatment modifications to minimize or prevent permanent hearing loss and balance impairment. Although many ototoxicity monitoring protocols exist, their practicality is questionable due to several factors. Even though the existing protocols have proven to be effective, certain lacunae in practice have been encountered due to discrepancies among recommended protocols. Implementation of these protocols is mostly held back due to the incapacitated status of the patient. The choice of early ototoxicity identification techniques is still debatable due to variables such as high degree of sensitivity, specificity and reliability, less time consumption and less labour-intensive to the patient. Hence, the diagnosis and effective treatment of ototoxicity is challenging, even today. A stringent protocol with more practicality encompassing all elements aimed at profiling the effects of ototoxicity is greatly needed. This review describes an efficient application of ototoxicity monitoring and treatment protocol as an attempt to reduce the challenges in diagnosis and management of ototoxicity. PMID- 29471611 TI - Update on Bone-Conduction Auditory Brainstem Responses: A Review. AB - Auditory brainstem responses (ABR) have been used as a powerful and the most common objective tool to evaluate hearing sensitivity and to diagnose the types of hearing loss and neurological disorders, through the auditory peripheral pathway to a central level of the brainstem, since 1971. Although bone-conduction (BC) ABR could be an alternative to air-conduction (AC) ABR, as the former overcomes some limitations of the latter, the majority of clinicians rarely utilize it due to a lack of knowledge and no routine test administration. This review presents the weaknesses of AC ABR that apply to all clinical population, and discusses the development of BC ABR. The optimal placements of bone oscillators to obtain favorable clinical outcomes in infants, children, and adults, and the appropriate stimuli for BC ABR are examined. While providing absolute thresholds and latencies of BC ABR based on previous studies compared to AC ABR, this review includes clinical data of infants and young children with both normal hearing in terms of maturation, and with pathology such as congenital external auditory canal atresia. We recommend the future clinical application of BC ABR for candidacy as well as for patients with BC hearing implants.

AB - Background and Objectives: To prevent noise induced hearing losses caused by listening to music with personal listening devices for young adults, this study was aimed to measure output levels of an MP3 and to identify preferred listening levels (PLLs) depending on earphone types, music genres, and listening durations. Subjects and METHODS: Twenty-two normal hearing young adults (mean=18.82, standard deviation=0.57) participated. Each participant was asked to select his or her most PLLs when listened to Korean ballade or dance music with an earbud or an over-the-ear earphone for 30 or 60 minutes. One side of earphone was connected to the participant's better ear and the other side was connected to a sound level meter via a 2 or 6 cc-couplers. Depending on earphone types, music genres, and listening durations, loudness A-weighted equivalent (LAeq) and loudness maximum time-weighted with A-frequency sound levels in dBA were measured. RESULTS: Neither main nor interaction effects of the PLLs among the three factors were significant. Overall output levels of earbuds were about 10-12 dBA greater than those of over-the-ear earphones. The PLLs were 1.73 dBA greater for earbuds than over-the-ear earphones. The average PLL for ballad was higher than for dance music. The PLLs at LAeq for both music genres were the greatest at 0.5 kHz followed by 1, 0.25, 2, 4, 0.125, 8 kHz in the order. Conclusions: The PLLs were not different significantly when listening to Korean ballad or dance music as functions of earphone types, music genres, and listening durations. However, over the-ear earphones seemed to be more suitable to prevent noise induce hearing loss when listening to music, showing lower PLLs, possibly due to isolation from the background noise by covering ears. PMID- 29471613 TI - Examination of Previously Published Data to Identify Patterns in the Social Representation of 'Hearing Aids' Across Countries. AB - BACKGROUND AND OBJECTIVES: Societal factors seem to exercise a strong influence on hearing aid uptake, use, and satisfaction. In particular, knowledge, perception, and attitude of people will have bearing towards their and others health behavior and decisions. The current study aimed at understanding the perception of hearing aids by adults belonging to the general population in different countries. SUBJECTS AND METHODS: The study employed a crosssectional design. A sample of 404 adults from India, Iran, Portugal, and the United Kingdom were recruited by relying on a convenience sampling. Previously published data was re-analyzed but it was applied for different approach. Free association task was used to collect the data. They were asked to provide up to five words or phrases that come to mind when thinking about "hearing aids." The data was initially analyzed based on qualitative content analysis. This was followed by quantitative cluster analysis and chi square analysis. RESULTS: The content analysis suggested 39 main categories of responses related to hearing aids. The cluster analysis resulted in five main clusters, namely: 1) positive attitude, 2) external factors, 3) hearing aid use and satisfaction, 4) etiology, and 5) benefits and limitations of technology. A few demographic factors (i.e., education, occupation type, country) showed association with different clusters, although country of origin seemed to be associated with most clusters. CONCLUSIONS: The study provides us with unique insights into the perception of hearing aids by the general public, and additionally, the way demographic variables may influence these perceptions.

AB - Once considered an incurable disease, the continuous evolution of technologies and techniques has improved both oncological outcomes and quality of life for patients with rectal cancer. Multiport laparoscopic surgery for rectal cancer is the standard of care in many institutions and countries and is the approach that has been most subjected to controlled trial. Following a number of randomized trials as well as large series and registry reports and several Cochrane reviews, there is no evidence of any oncological disadvantage to laparoscopic surgery compared with the open approach and there is good evidence of improved short-term outcomes and some evidence of improved long-term outcomes. We describe the "standard" approach to multiport, laparoscopic low anterior resection.

PMID- 29471616 TI - Non-operative management of rectal cancer: future perspectives turning into reality? AB - The management of rectal cancer has considerably changed over the last decades and complete response to neoadjuvant chemoradiotherapy is becoming a common clinical entity. There is still no consensus on the definition of complete response to neoadjuvant treatment prior to surgery. Treatment programs are mostly heterogeneous and non-randomized. In addition, techniques to diagnose complete response are still unclear and there is no uniformity in surveillance modality of those patients managed without operative intervention. We review the most recent evidences reported in literature. PMID- 29471617 TI - How to reduce surgical complications in rectal cancer surgery using fluorescence techniques. AB - Anastomotic leakage (AL) is a serious complication in colorectal surgery leading to significant morbidity and mortality. Progressively lower anastomoses are associated with a greater leak rate. Adequate bowel perfusion has been stressed as one of the key elements for suture healing. Currently, there is no widespread method to assess and quantify the perfusion of gastrointestinal anastomoses intraoperatively, besides the subjective evaluation by the surgeon. The aim of this paper is to describe the basis of Indocyanine Green (ICG) fluorescence guided surgery applied to assessment of bowel perfusion and to highlight studies on the use of fluorescence angiography (FA) in laparoscopic rectal surgery. ICG fluorescence guided surgery has increasingly been used as a tool for intraoperative diagnostics to assess microperfusion and viability of tissues by means of a real-time FA; this technique has achieved the role of major contribution to intraoperative decision making during surgical procedures, especially in order to assess bowel perfusion before anastomosis creation in colorectal surgery. Several studies in literature already reported that ICG FA as a feasible technique to decrease AL rate in colorectal surgery; to date no randomized controlled trials have been completed but large series and prospective studies that focus on fluorescence perfusion assessment in rectal surgery have been published. Real time intraoperative ICG fluorescent angiography (FA) is a safe and feasible technique to guide the surgeon in intraoperative decision making process. ICG FA seems to reduce AL rates following rectal surgery for cancer. However large well-designed RCTs are needed to provide evidence for its routine use. PMID- 29471619 TI - Post-surgical recurrence of hepatocellular carcinoma along resection margin treated by percutaneous US-guided ablation. AB - BACKGROUND: The aim of this study was to evaluate the safety and efficacy of percutaneous ablation for hepatocellular carcinoma (HCC) hepatic recurrence along surgical resection margins to achieve complete cure or bridge for additional treatment. No current recommendations exist for these lesions. METHODS: Retrospective review of post-surgical recurrent HCC located along surgical margins treated by percutaneous ultrasound-guided ablation from 2006-2014. Ablation was performed by radiofrequency ablation (RFA) or percutaneous ethanol injection (PEI), selected for recurrence in proximity to extrahepatic organs. RESULTS: In total, nine patients (49-82 y, mean 73.8+/-8.3) were treated for 13 recurrent HCC nodules (9-35 mm, mean 21.5+/-8.1) located along resection margins by RFA (11 nodules) and PEI (2 nodules). Mean time between surgery and percutaneous ablation was 64 months (range 10-149). At a mean follow-up of 17 months (+/-9), complete ablation was achieved in 9 nodules (69.2%, 8 after RF, 1 after PEI) and partial ablation was achieved in 4 nodules (3 after RFA, 1 after PEI). Complications were limited to minor abdominal pain in 2 patients requiring medical therapy (15.3%). Of the 4 partially ablated nodules, subsequent therapy achieved complete response in 3 nodules (1 patient with TACE, 1 patient with stereotactic radiotherapy, and one with liver transplantation), while the last nodule progressed despite subsequent TACE. CONCLUSIONS: HCC recurrence along the surgical margin can be safely and effectively treated by percutaneous therapy, despite the misconception of the surgical margin as a hostile location. Percutaneous treatment may bridge the patient for additional therapy. PMID- 29471618 TI - Visual probing of rectal neoplasia: near-infrared interrogation of primary tumors and secondary lymph nodes. AB - Laparoscopic and endoscopic colorectal intervention and operations have their basis in real-time, image-based decision-making and step-by-step sequenced technical progress. The capacity to visualize accurately malignant disease wherever it may be including within the primary lesion and its draining lymph node basin as well as at potential sites of metastatic harbor (i.e. peritoneum, liver and lung) would allow more accurate surgery at the time of operation and enable personalized, stratified surgical intervention. In addition, such capacity could efficiently compress the diagnostic and therapeutic stages of a patient's progress from presentation, through work-up and onto appropriate treatment, important in this era of restricted resource and increased user demand. Near infrared endolaparoscopic illumination enables broad spectral imaging of tissue in situ, most often, at present, in conjunction with the approved safe and low cost fluorophore indocyanine green. While additional targeted agents are in development, here we detail how this developed and available technology may be used as a visual probe of neoplasia to inform surgeons regarding functional, tissue characterization through the direct observation of metabolic and metabolomic processes within the area under inspection perhaps helping in the distinction between invasive cancer and non-invasive dysplastic lesions. This understanding can inform and accelerate development of specific agents and techniques that can better advance surgical practice into the era of surgical data science and true precision surgery. PMID- 29471620 TI - Augmented reality for breast imaging. AB - Augmented reality (AR) enables the superimposition of virtual reality reconstructions onto clinical images of a real patient, in real time. This allows visualization of internal structures through overlying tissues, thereby providing a virtual transparency vision of surgical anatomy. AR has been applied to neurosurgery, which utilizes a relatively fixed space, frames, and bony references; the application of AR facilitates the relationship between virtual and real data. Augmented breast imaging (ABI) is described. Breast MRI studies for breast implant patients with seroma were performed using a Siemens 3T system with a body coil and a four-channel bilateral phased-array breast coil as the transmitter and receiver, respectively. Gadolinium was injected as a contrast agent (0.1 mmol/kg at 2 mL/s) using a programmable power injector. Dicom formatted images data from 10 MRI cases of breast implant seroma and 10 MRI cases with T1-2 N0 M0 breast cancer, were imported and transformed into augmented reality images. ABI demonstrated stereoscopic depth perception, focal point convergence, 3D cursor use, and joystick fly-through. ABI can improve clinical outcomes, providing an enhanced view of the structures to work on. It should be further studied to determine its utility in clinical practice. PMID- 29471621 TI - Oncoplastic breast reduction in conservative surgery. AB - Advances in reconstructive breast surgery with new materials and techniques now allow us to offer patients the best possible cosmetic results without the risks associated with oncological control of the disease. These advances, in both oncological and plastic surgery, have led to a new field, oncoplastic breast surgery, which enables us to undertake large resections and, with advance planning, and prevent subsequent deformities. This is particularly important when more than 30% of the breast volume is removed, as it allows us to obtain precise information for conservative surgery according to the site of the lesion and to set the boundary between conservative surgery and mastectomy. PMID- 29471622 TI - Effectiveness of influenza vaccine in preventing medically-attended influenza virus infection in primary care, Israel, influenza seasons 2014/15 and 2015/16. AB - IntroductionInfluenza vaccine is recommended for the entire population in Israel. We assessed influenza vaccine effectiveness (VE) for the 2014/15 and 2015/16 seasons in Israel, for the first time. Methods: Combined nose and throat swab specimens were collected from patients with influenza-like illness (ILI) presenting to sentinel primary care clinics and tested for influenza virus by RT PCR. VE of the trivalent inactivated vaccine (TIV) was assessed using test negative case-control design. Results: During the 2014/15 season 1,142 samples were collected; 327 (28.6%) were positive for influenza, 83.8% A(H3N2), 5.8% A(H1N1)pdm09, 9.2% B and 1.2% A un-subtyped. Adjusted VE against all influenza viruses for this influenza season was -4.8% (95% confidence interval (CI): -54.8 to 29.0) and against influenza A(H3N2), it was -15.8% (95% CI: -72.8 to 22.4). For the 2015/16 season, 1,919 samples were collected; 853 (44.4%) were positive for influenza, 43.5% A(H1N1)pdm09, 57% B, 0.7% A(H3N2) and 11 samples positive for both A(H1N1)pdm09 and B. Adjusted VE against all influenza viruses for this influenza season was 8.8% (95% CI: -25.1 to 33.5), against influenza A(H1N1)pdm09, it was 32.3% (95% CI: (-4.3 to 56.1) and against influenza B, it was -2.2% (95% CI: (-47.0 to 29.0). Conclusions: Using samples from patients with ILI visiting sentinel clinics in Israel, we demonstrated the feasibility of influenza VE estimation in Israel. PMID- 29471623 TI - Monitoring human enteric viruses in wastewater and relevance to infections encountered in the clinical setting: a one-year experiment in central France, 2014 to 2015. AB - BackgroundHuman enteric viruses are resistant in the environment and transmitted via the faecal-oral route. Viral shedding in wastewater gives the opportunity to track emerging pathogens and study the epidemiology of enteric infectious diseases in the community. Aim: The aim of this study was to monitor the circulation of enteric viruses in the population of the Clermont-Ferrand area (France) by analysis of urban wastewaters. Methods: Raw and treated wastewaters were collected between October 2014 and October 2015 and concentrated by a two step protocol using tangential flow ultrafiltration and polyethylene glycol precipitation. Processed samples were analysed for molecular detection of adenovirus, norovirus, rotavirus, parechovirus, enterovirus (EV), hepatitis A (HAV) and E (HEV) viruses. Results: All wastewater samples (n = 54) contained viruses. On average, six and four virus species were detected in, respectively, raw and treated wastewater samples. EV-positive samples were tested for EV-D68 to assess its circulation in the community. EV-D68 was detected in seven of 27 raw samples. We collected data from clinical cases of EV-D68 (n = 17), HAV (n = 4) and HEV infection (n = 16) and compared wastewater-derived sequences with clinical sequences. We showed the silent circulation of EV-D68 in September 2015, the wide circulation of HAV despite few notifications of acute disease and the presence in wastewater of the major HEV subtypes involved in clinical local cases. Conclusion: The environmental surveillance overcomes the sampling bias intrinsic to the study of infections associated with hospitalisation and allows the detection in real time of viral sequences genetically close to those reported in clinical specimens.

AB - An anodic oxidation/cyclization of 2-arylbenzoic acids for the synthesis of dibenzopyranones has been developed. The reaction proceeds at room temperature with no oxidant or electrolyte required and exhibits a high atom economy with H2 being the only byproduct. A series of dibenzopyranones was obtained in good to excellent yields. Urolithins A, B, and C are formally synthesized by adopting this method as a key step to demonstrate its synthetic utility. PMID- 29471624 TI - Interim effectiveness of trivalent influenza vaccine in a season dominated by lineage mismatched influenza B, northern Spain, 2017/18. AB - The 2017/18 interim estimate of trivalent influenza vaccine effectiveness (VE) was 39% (95% confidence interval: 20-54) in Navarre. Compared with individuals unvaccinated in the current and five previous seasons, VE against influenza B was 41% for current and any prior doses, 67% for current vaccination only, and 22% for any prior doses, and 43%, 51% and 54%, respectively against influenza A(H3N2). This suggests moderate VE despite predominance of lineage mismatched influenza B. PMID- 29471629 TI - Biocompatible Microporous Organically Modified Silicate Material with Rapid Internal Diffusion of Protons. AB - A new four-component organically modified silicate (ORMOSIL) material was developed with optical pH sensors in mind. Through a sol-gel process, the porosity of an ORMOSIL framework was optimized to allow rapid diffusion of protons, ideal for fast response to pH in an optical sensor. The optically transparent material was produced by catalyzing the dual polymerization of 3 (glycidoxy)propyltrimethoxysilane (GPTMS) and propyltriethoxysilane (PrTES) with boron trifluoride diethyl etherate. The performance of the resulting material in fluorescence based optical pH sensors was evaluated by incorporation of active dye components in the inorganic polymer framework. It is demonstrated that the material has a short response time ( t90 < 30 s) and high stability in medium and during storage, and resulting sensor spots are biocompatible. It is concluded that this ORMOSIL material has excellent properties for optical pH sensors. PMID- 29471628 TI - Activation of Pyruvate Dehydrogenase by Sodium Dichloroacetate Shifts Metabolic Consumption from Amino Acids to Glucose in IPEC-J2 Cells and Intestinal Bacteria in Pigs. AB - The extensive metabolism of amino acids (AA) as fuel is an important reason for the low use efficiency of protein in pigs. In this study, we investigated whether regulation of the pyruvate dehydrogenase kinase (PDK)/pyruvate dehydrogenase alpha 1 (PDHA1) pathway affected AA consumption by porcine intestinal epithelial (IPEC-J2) cells and intestinal bacteria in pigs. The effects of knockdown of PDHA1 and PDK1 with small interfering RNA (siRNA) on nutrient consumption by IPEC J2 cells were evaluated. IPEC-J2 cells were then cultured with sodium dichloroacetate (DCA) to quantify AA and glucose consumption and nutrient oxidative metabolism. The results showed that knockdown of PDHA1 using siRNA decreased glucose consumption but increased total AA (TAA) and glutamate (Glu) consumption by IPEC-J2 cells ( P < 0.05). Opposite effects were observed using siRNA targeting PDK1 ( P < 0.05). Additionally, culturing IPEC-J2 cells in the presence of 5 mM DCA markedly increased the phosphorylation of PDHA1 and PDH phosphatase 1, but inhibited PDK1 phosphorylation ( P < 0.05). DCA treatment also reduced TAA and Glu consumption and increased glucose depletion ( P < 0.05). These results indicated that PDH was the regulatory target for shifting from AA metabolism to glucose metabolism and that culturing cells with DCA decreased the consumption of AAs by increasing the depletion of glucose through PDH activation.

PMID- 29471630 TI - Ir(III)/MPAA-Catalyzed Mild and Selective C-H Amidation of N-Sulfonyl Ketimines: Access To Benzosultam-Fused Quinazolines/Quinazolinones. AB - Ir(III)-catalyzed unprecedented mild C-H amidation for weakly coordinating cyclic N-sulfonyl ketimines, accelerated by a mono protected l-amino acid, has been developed. The method uses 1,4,2-dioxazol-5-ones as the robust amidating reagent in conjunction with a catalytic amount of silver triflate. It is highly selective and does not require a stoichiometric amount of oxidants or additives. A series of mechanistic experiments was performed to gain some insights into the reaction mechanism. The strategy provides easy access to novel benzosultam-quinazoline and benzosultam-quinazolinone hybrid scaffolds endowed with pharmaceutically relevant features. PMID- 29471634 TI - Force fields for monovalent and divalent metal cations in TIP3P water based on thermodynamic and kinetic properties. AB - Metal cations are essential in many vital processes. In order to capture the role of different cations in all-atom molecular dynamics simulations of biological processes, an accurate parametrization is crucial. Here, we develop force field parameters for the metal cations Li+, Na+, K+, Cs+, Mg2+, Ca2+, Sr2+, and Ba2+ in combination with the TIP3P water model that is frequently used in biomolecular simulations. In progressing toward improved force fields, the approach presented here is an extension of previous efforts and allows us to simultaneously reproduce thermodynamic and kinetic properties of aqueous solutions. We systematically derive the parameters of the 12-6 Lennard-Jones potential which accurately reproduces the experimental solvation free energy, the activity derivative, and the characteristics of water exchange from the first hydration shell of the metal cations. In order to reproduce all experimental properties, a modification of the Lorentz-Berthelot combination rule is required for Mg2+. Using a balanced set of solution properties, the optimized force field parameters aim to capture the fine differences between distinct metal cations including specific ion binding affinities and the kinetics of cation binding to biologically important anionic groups. PMID- 29471635 TI - Global potential energy surface of ground state singlet spin O4. AB - A new global potential energy for the singlet spin state O4 system is reported using CASPT2/aug-cc-pVTZ ab initio calculations. The geometries for the six dimensional surface are constructed using a novel point generation scheme that employs randomly generated configurations based on the beta distribution. The advantage of this scheme is apparent in the reduction of the number of required geometries for a reasonably accurate potential energy surface (PES) and the consequent decrease in the overall computational effort. The reported surface matches well with the recently published singlet surface by Paukku et al. [J. Chem. Phys. 147, 034301 (2017)]. In addition to the O4 PES, the ground state N4 PES is also constructed using the point generation scheme and compared with the existing PES [Y. Paukku et al., J. Chem. Phys. 139, 044309 (2013)]. The singlet surface is constructed with the aim of studying high energy O2-O2 collisions and predicting collision induced dissociation cross section to be used in simulating non-equilibrium aerothermodynamic flows. PMID- 29471636 TI - Semiclassical analysis of jm -> j'm' transitions in rotationally inelastic collisions in cell experiments. AB - Recent quantum calculations of rotationally inelastic collisions of NaK (A1Sigma+) with He or Ar in a cell experiment are analyzed using semiclassical approximations valid for large quantum numbers. The results suggest a physical interpretation of jm -> j'm' transitions based on the vector model and lead to expressions that explicitly involve the initial and final polar angles of the angular momentum of the target molecule. The relation between the polar angle theta and the azimuthal quantum number m links the semiclassical results for the change in polar angle (theta -> theta') to quantum results for an m -> m' transition. Analytic formulas are derived that relate the location and width of peaks in the final polar angle distribution (PAD) to the K-dependence of the coefficients dK(j, j'), which are proportional to tensor cross sections sigmaK(j > j'). Several special cases are treated that lead to final PADs that are approximately Lorentzian or sinc functions centered at theta' = theta. Another interesting case, "angular momentum reversal," was observed in the calculations for He. This phenomenon, which involves a reversal of the direction of the target's angular momentum, is shown to be associated with oscillatory behavior of the dK for certain transitions. Finally, several strategies for obtaining the dK coefficients from experimental data are discussed. PMID- 29471637 TI - Adsorption of squaraine molecules to Au(111) and Ag(001) surfaces. AB - The adsorption of anilino squaraines, an important chromophore for the use in organic solar cells, to Ag(001) and Au(111) has been studied with scanning tunneling microscopy. Self-assembly into square building blocks with eight molecules per unit cell is revealed on the Ag surface, while no ordering effects occur on gold. The squaraine-silver interaction is mediated by the carbonyl and hydroxyl oxygens located in the center of the molecule. The intermolecular coupling, on the other hand, is governed by hydrogen bonds formed between the terminal isobutyl groups and oxygen species of adjacent molecules. The latter gets maximized by rotating the molecules by a few degrees against a perfect square alignment. A similar molecular pattern does not form on Au(111) due to symmetry mismatch. Moreover, the high electronegativity of gold reduces the directing effect of oxygen-metal bonds that trigger the ordering process on silver. As a consequence, only frustrated three-fold symmetric units that do not expand into an ordered molecular network are present on the gold surface. PMID- 29471638 TI - Monitoring polariton dynamics in the LHCII photosynthetic antenna in a microcavity by two-photon coincidence counting. AB - The relaxation dynamics of light-harvesting complex II in an optical cavity is explored theoretically by multidimensional photon coincidence counting spectroscopy. This technique reveals the dynamics in both single (e) and double (f) excitation bands. We study how the polariton dynamics are affected by coupling to photon modes and molecular vibrations described by a realistic spectral density at 77 K. Without the cavity, the e- and f-band energy transfer pathways are not clearly resolved due to the line broadening caused by fast exciton dephasing. The strong coupling to cavity photons results in well-resolved polariton modes. The hybrid nature of polaritons slows down their energy transfer rates. PMID- 29471639 TI - Using monomer vibrational wavefunctions to compute numerically exact (12D) rovibrational levels of water dimer. AB - We compute numerically exact rovibrational levels of water dimer, with 12 vibrational coordinates, on the accurate CCpol-8sf ab initio flexible monomer potential energy surface [C. Leforestier et al., J. Chem. Phys. 137, 014305 (2012)]. It does not have a sum-of-products or multimode form and therefore quadrature in some form must be used. To do the calculation, it is necessary to use an efficient basis set and to develop computational tools, for evaluating the matrix-vector products required to calculate the spectrum, that obviate the need to store the potential on a 12D quadrature grid. The basis functions we use are products of monomer vibrational wavefunctions and standard rigid-monomer basis functions (which involve products of three Wigner functions). Potential matrix vector products are evaluated using the F matrix idea previously used to compute rovibrational levels of 5-atom and 6-atom molecules. When the coupling between inter- and intra-monomer coordinates is weak, this crude adiabatic type basis is efficient (only a few monomer vibrational wavefunctions are necessary), although the calculation of matrix elements is straightforward. It is much easier to use than an adiabatic basis. The product structure of the basis is compatible with the product structure of the kinetic energy operator and this facilitates computation of matrix-vector products. Compared with the results obtained using a [6 + 6]D adiabatic approach, we find good agreement for the inter-molecular levels and larger differences for the intra-molecular water bend levels. PMID- 29471640 TI - Temperature dependence of dissociative electron attachment to bromo-chlorotoluene isomers: Competition between detachment of Cl- and Br. AB - Dissociative electron attachment to three isomers of bromo-chlorotoluene was investigated in the electron energy range from 0 to 2 eV for gas temperatures in the range of 392-520 K using a crossed electron-molecular beam apparatus with a temperature regulated effusive molecular beam source. For all three molecules, both Cl- and Br- are formed. The ion yields of both halogenides show a pronounced temperature effect. In the case of Cl- and Br-, the influence of the gas temperature can be observed at the threshold peak close to 0 eV. The population of molecules that have some of their out-of-plane modes excited varies strongly in the temperature range investigated, indicating that such vibrations might play a role in the energy transfer towards bond breaking. Potential energy curves for the abstraction of Cl- and Br- were calculated and extrapolated into the metastable domain. The barriers in the diabatic curves approximated in this way agree well with the ones derived from the temperature dependence observed in the experiments. PMID- 29471641 TI - Origin of the size-dependence of the equilibrium van der Waals binding between nanostructures. AB - Nanostructures can be bound together at equilibrium by the van der Waals (vdW) effect, a small but ubiquitous many-body attraction that presents challenges to density functional theory. How does the binding energy depend upon the size or number of atoms in one of a pair of identical nanostructures? To answer this question, we treat each nanostructure as a whole object, not as a collection of atoms. Our calculations start from an accurate static dipole polarizability for each considered nanostructure, and an accurate equilibrium center-to-center distance for the pair (the latter from experiment or from the vdW-DF-cx functional). We consider the competition in each term -C2k/d2k (k = 3, 4, 5) of the long-range vdW series for the interaction energy, between the size dependence of the vdW coefficient C2k and that of the 2kth power of the center-to-center distance d. The damping of these vdW terms can be negligible, but in any case, it does not affect the size dependence for a given term in the absence of non-vdW binding. To our surprise, the vdW energy can be size-independent for quasi spherical nanoclusters bound to one another by vdW interaction, even with strong nonadditivity of the vdW coefficient, as demonstrated for fullerenes. We also show that, for low-dimensional systems, the vdW interaction yields the strongest size-dependence, in stark contrast to that of fullerenes. We illustrate this with parallel planar polycyclic aromatic hydrocarbons. The size dependences of other morphologies or bonding types lie between, as shown by sodium clusters. PMID- 29471642 TI - Linear and non-linear infrared response of one-dimensional vibrational Holstein polarons in the anti-adiabatic limit: Optical and acoustical phonon models. AB - The theory of linear and non-linear infrared response of vibrational Holstein polarons in one-dimensional lattices is presented in order to identify the spectral signatures of self-trapping phenomena. Using a canonical transformation, the optical response is computed from the small polaron point of view which is valid in the anti-adiabatic limit. Two types of phonon baths are considered: optical phonons and acoustical phonons, and simple expressions are derived for the infrared response. It is shown that for the case of optical phonons, the linear response can directly probe the polaron density of states. The model is used to interpret the experimental spectrum of crystalline acetanilide in the C=O range. For the case of acoustical phonons, it is shown that two bound states can be observed in the two-dimensional infrared spectrum at low temperature. At high temperature, analysis of the time-dependence of the two-dimensional infrared spectrum indicates that bath mediated correlations slow down spectral diffusion. The model is used to interpret the experimental linear-spectroscopy of model alpha-helix and beta-sheet polypeptides. This work shows that the Davydov Hamiltonian cannot explain the observations in the NH stretching range. PMID- 29471643 TI - Optimization of long range potential interaction parameters in ion mobility spectrometry. AB - The problem of optimizing Lennard-Jones (L-J) potential parameters to perform collision cross section (CCS) calculations in ion mobility spectrometry has been undertaken. The experimental CCS of 16 small organic molecules containing carbon, hydrogen, oxygen, nitrogen, and fluoride in N2 was compared to numerical calculations using Density Functional Theory (DFT). CCS calculations were performed using the momentum transfer algorithm IMoS and a 4-6-12 potential without incorporating the ion-quadrupole potential. A ceteris paribus optimization method was used to optimize the intercept sigma and potential well depth epsilon for the given atoms. This method yields important information that otherwise would remain concealed. Results show that the optimized L-J parameters are not necessarily unique with intercept and well-depth following an exponential relation at an existing line of minimums. Similarly, the method shows that some molecules containing atoms of interest may be ill-conditioned candidates to perform optimizations of the L-J parameters. The final calculated CCSs for the chosen parameters differ 1% on average from their experimental counterparts. This result conveys the notion that DFT calculations can indeed be used as potential candidates for CCS calculations and that effects, such as the ion-quadrupole potential or diffuse scattering, can be embedded into the L-J parameters without loss of accuracy but with a large increase in computational efficiency.

AB - Magnetism and magnetic anisotropy energy (MAE) of the Ge3Mn5 bulk, free-standing surface, and Ge3Mn5(001)|Ge(111) thinfilms and superlattice have been systemically investigated by using the relativistic first-principles electronic structure calculations. For Ge3Mn5 adlayers on Ge(111) substrates within Mn1 termination, the direction of magnetization undergoes a transition from in-plane at 1 monolayer (ML) thickness (MAE = -0.50 meV/ML) to out-of-plane beginning at 3 ML thickness (nearly invariant MAE = 0.16 meV/ML). The surficial/interfacial MAE is extracted to be 1.23/-0.54 meV for Mn1-termination; the corresponding value is 0.19/1.03 meV for Mn2/Ge-termination; the interior MAE is averaged to be 0.09 meV per ML. For various Ge3Mn5 systems, the in-plane lattice expansion and/or interlayer distance contraction would enhance the out-of-plane MAE. Our theoretical magnetic moments and MAEs fit well with the experimental measurements. Finally, the origination of MAE is elucidated under the framework of second-order perturbation with the electronic structure analyses.

PMID- 29471646 TI - Computing energy levels of CH4, CHD3, CH3D, and CH3F with a direct product basis and coordinates based on the methyl subsystem. AB - Quantum mechanical calculations of ro-vibrational energies of CH4, CHD3, CH3D, and CH3F were made with two different numerical approaches. Both use polyspherical coordinates. The computed energy levels agree, confirming the accuracy of the methods. In the first approach, for all the molecules, the coordinates are defined using three Radau vectors for the CH3 subsystem and a Jacobi vector between the remaining atom and the centre of mass of CH3. Euler angles specifying the orientation of a frame attached to CH3 with respect to a frame attached to the Jacobi vector are used as vibrational coordinates. A direct product potential-optimized discrete variable vibrational basis is used to build a Hamiltonian matrix. Ro-vibrational energies are computed using a re-started Arnoldi eigensolver. In the second approach, the coordinates are the spherical coordinates associated with four Radau vectors or three Radau vectors and a Jacobi vector, and the frame is an Eckart frame. Vibrational basis functions are products of contracted stretch and bend functions, and eigenvalues are computed with the Lanczos algorithm. For CH4, CHD3, and CH3D, we report the first J > 0 energy levels computed on the Wang-Carrington potential energy surface [X.-G. Wang and T. Carrington, J. Chem. Phys. 141(15), 154106 (2014)]. For CH3F, the potential energy surface of Zhao et al. [J. Chem. Phys. 144, 204302 (2016)] was used. All the results are in good agreement with experimental data.

AB - The surface reactivity and hydrophilicity of silicate materials are key properties for various industrial applications. However, the structural origin of their affinity for water remains unclear. Here, based on reactive molecular dynamics simulations of a series of artificial glassy silica surfaces annealed at various temperatures and subsequently exposed to water, we show that silica exhibits a hydrophilic-to-hydrophobic transition driven by its silanol surface density. By applying topological constraint theory, we show that the surface reactivity and hydrophilic/hydrophobic character of silica are controlled by the atomic topology of its surface. This suggests that novel silicate materials with tailored reactivity and hydrophilicity could be developed through the topological nanoengineering of their surface.

AB - We present a comparative study on the calculated cross sections obtained for the elastic collisions of low-energy electrons with the amino acid proline (C5H9NO2) and its building block pyrrolidine (C4H9N). We employed the Schwinger multichannel method implemented with pseudopotentials to compute integral, differential, and momentum transfer cross sections in the static-exchange plus polarization approximation, for energies up to 15 eV. We report three shape resonances for proline at around 1.7 eV, 6.8 eV, and 10 eV and two shape resonances for pyrrolidine centered at 7 eV and 10.2 eV. The present resonance energies are compared with available experimental data on vertical attachment energies and dissociative electron attachment, where a good agreement is found. From the comparison of the present results with available calculated cross sections for the simplest carboxylic acid, formic acid (HCOOH), and from electronic structure calculations, we found that the first resonance of proline, at 1.7 eV, is due the presence of the carboxylic group, whereas the other two structures, at 6.8 eV and 10 eV, clearly arise from the pyrrolidine ring. A comparison between the differential cross sections for proline and pyrrolidine at some selected energies of the incident electron is also reported in this paper. PMID- 29471650 TI - Electronic annealing Fermi operator expansion for DFT calculations on metallic systems. AB - Density Functional Theory (DFT) calculations with computational effort which increases linearly with the number of atoms (linear-scaling DFT) have been successfully developed for insulators, taking advantage of the exponential decay of the one-particle density matrix. For metallic systems, the density matrix is also expected to decay exponentially at finite electronic temperature and linear scaling DFT methods should be possible by taking advantage of this decay. Here we present a method for DFT calculations at finite electronic temperature for metallic systems which is effectively linear-scaling (O(N)). Our method generates the elements of the one-particle density matrix and also finds the required chemical potential and electronic entropy using polynomial expansions. A fixed expansion length is always employed to generate the density matrix, without any loss in accuracy by the application of a high electronic temperature followed by successive steps of temperature reduction until the desired (low) temperature density matrix is obtained. We have implemented this method in the ONETEP linear scaling (for insulators) DFT code which employs local orbitals that are optimised in situ. By making use of the sparse matrix machinery of ONETEP, our method exploits the sparsity of Hamiltonian and density matrices to perform calculations on metallic systems with computational cost that increases asymptotically linearly with the number of atoms. We demonstrate the linear-scaling computational cost of our method with calculation times on palladium nanoparticles with up to ~13 000 atoms.

AB - High fidelity and robustness in population inversion is very desirable for many quantum control applications. We expand composite pulse schemes developed for two level dynamics and present an analytic solution for the coherent evolution of an N-level quantum system with SU(2) symmetry, for achieving high fidelity and robust population inversion. Our approach offers a platform for accurate steering of the population transfer in physical multi-level systems, which is crucial for fidelity in quantum computation and achieving fundamental excitations in nuclear magnetic resonances and atomic physics. We also introduce and discuss the geometrical trajectories of these dynamics on the Majorana sphere as an interpretation, allowing us to gain physical insight on the dynamics of many-body or high-dimensional quantum systems. PMID- 29471652 TI - Formation and identification of borane radical anions isolated in solid argon. AB - The infrared (IR) spectrum of borane(3) anions (BH3-) isolated in solid Ar was recorded; two vibrational modes were observed at 2259.4 and 606.6 cm-1, which were assigned to the BH2 stretching (nu3) and out-of-plane large-amplitude (nu2) modes, respectively. These anions were produced by the electron bombardment of an Ar matrix sample containing a small proportion of B2H6 and H2 during matrix deposition or by the photolysis of single-bridged-B2H5- in an Ar matrix with the selected ultraviolet light. The band positions, relative intensity ratios, isotopic splitting pattern, and isotopic shift ratios of the observed IR features of BH3- are generally in good agreement with those predicted by the B2PLYP/aug-cc pVTZ method.

PMID- 29471653 TI - Quantifying entanglement of rotor chains using basis truncation: Application to dipolar endofullerene peapods. AB - We propose a variational approach for the calculation of the quantum entanglement entropy of assemblies of rotating dipolar molecules. A basis truncation scheme based on the total angular momentum quantum number is proposed. The method is tested on hydrogen fluoride (HF) molecules confined in C60 fullerene cages themselves trapped in a nanotube to form a carbon peapod. The rotational degrees of freedom of the HF molecules and dipolar interactions between neighboring molecules are considered in our model Hamiltonian. Both screened and unscreened dipoles are simulated and results are obtained for the ground state and one excited state that is expected to be accessible via a far-infrared collective excitation. The effect of basis truncation on energetic and entanglement properties is examined and discussed in terms of size extensivity. It is empirically found that for unscreened dipoles, a total angular momentum cutoff that increases linearly with the number of rotors is required in order to obtain proper system size scaling of the chemical potential and entanglement entropy. Recent experiments [A. Krachmalnicoff et al., Nat. Chem. 8, 953 (2016)] suggest substantial screening of the HF dipole moment, so much smaller basis sets are required to obtain converged results in this realistic case. Static correlation functions are also computed and are shown to decay much quicker in the case of screened dipoles. Our variational results are also used to test the accuracy of perturbative and pairwise ansatz treatments. PMID- 29471655 TI - Long-lived transient anion of c-C4F8O. AB - We report partial cross sections for electron attachment to c-C4F8O, a gas with promising technological applications in free-electron-rich environments. The dissociative electron attachment leads to a number of anionic fragments resulting from complex bond-breaking and bond-forming processes. However, the anion with the highest abundance is the non-dissociated (transient) parent anion which is formed around 0.9 eV electron energy. Its lifetime reaches tens of microseconds. We discuss the origin of this long lifetime, the anion's strong interactions with other molecules, and the consequences for electron-scavenging properties of c C4F8O in denser environments, in particular for its use in mixtures with CO2 and N2. PMID- 29471657 TI - Time-dependent density functional theory description of total photoabsorption cross sections. AB - The time-dependent version of the density functional theory (TDDFT) has been used to calculate the total photoabsorption cross section of a number of molecules, namely, benzene, pyridine, furan, pyrrole, thiophene, phenol, naphthalene, and anthracene. The discrete electronic pseudo-spectra, obtained in a L2 basis set calculation were used in an analytic continuation procedure to obtain the photoabsorption cross sections. The ammonia molecule was chosen as a model system to compare the results obtained with TDDFT to those obtained with the linear response coupled cluster approach in order to make a link with our previous work and establish benchmarks. PMID- 29471656 TI - Cumulant expansions for measuring water exchange using diffusion MRI. AB - The rate of water exchange across cell membranes is a parameter of biological interest and can be measured by diffusion magnetic resonance imaging (dMRI). In this work, we investigate a stochastic model for the diffusion-and-exchange of water molecules. This model provides a general solution for the temporal evolution of dMRI signal using any type of gradient waveform, thereby generalizing the signal expressions for the Karger model. Moreover, we also derive a general nth order cumulant expansion of the dMRI signal accounting for water exchange, which has not been explored in earlier studies. Based on this analytical expression, we compute the cumulant expansion for dMRI signals for the special case of single diffusion encoding (SDE) and double diffusion encoding (DDE) sequences. Our results provide a theoretical guideline on optimizing experimental parameters for SDE and DDE sequences, respectively. Moreover, we show that DDE signals are more sensitive to water exchange at short-time scale but provide less attenuation at long-time scale than SDE signals. Our theoretical analysis is also validated using Monte Carlo simulations on synthetic structures. PMID- 29471658 TI - Excited-state dissociation dynamics of phenol studied by a new time-resolved technique. AB - Phenol is an important model molecule for the theoretical and experimental investigation of dissociation in the multistate potential energy surfaces. Recent theoretical calculations [X. Xu et al., J. Am. Chem. Soc. 136, 16378 (2014)] suggest that the phenoxyl radical produced in both the X and A states from the O H bond fission in phenol can contribute substantially to the slow component of photofragment translational energy distribution. However, current experimental techniques struggle to separate the contributions from different dissociation pathways. A new type of time-resolved pump-probe experiment is described that enables the selection of the products generated from a specific time window after molecules are excited by a pump laser pulse and can quantitatively characterize the translational energy distribution and branching ratio of each dissociation pathway. This method modifies conventional photofragment translational spectroscopy by reducing the acceptance angles of the detection region and changing the interaction region of the pump laser beam and the molecular beam along the molecular beam axis. The translational energy distributions and branching ratios of the phenoxyl radicals produced in the X, A, and B states from the photodissociation of phenol at 213 and 193 nm are reported. Unlike other techniques, this method has no interference from the undissociated hot molecules. It can ultimately become a standard pump-probe technique for the study of large molecule photodissociation in multistates. PMID- 29471659 TI - Thermodynamic properties of confined square-well fluids with multiple associating sites. AB - In this work, a molecular simulation study of confined hard-spheres particles with square-well (SW) attractive interactions with two and four associating SW sites based on the first-order perturbation form of Wertheim's theory is presented. An extended version of the Gibbs ensemble technique for inhomogeneous fluids [A. Z. Panagiotopoulos, Mol. Phys. 62, 701 (1987)] is used to predict the adsorption density profiles for associating fluids confined between opposite parallel walls. The fluid is confined in four kinds of walls: hard-wall, SW wall, Lennard-Jones (LJ) 12-6 wall potential, and LJ 10-4 wall potential. We analyze the behavior of the confined system for several supercritical temperatures as a function of variation of molecular parameters: potential range lambda, bulk densities rhob*, pore width H, cutoff range interaction rc*, and range of the potential and depth of the particle-wall (lambdaw, epsilonw*). Additionally, we include predictions for liquid-vapor coexistence of bulk associative particles and how their critical properties are modified by the presence of associative sites in the molecule. The molecular simulation data presented in this work are of prime importance to the development of theoretical approaches for inhomogeneous fluids as classical density functional theory. The simulation results presented here are resourceful for predicting adsorption isotherms of real associating fluids such as water. PMID- 29471660 TI - Molecular dynamics simulation for the test of calibrated OPLS-AA force field for binary liquid mixture of tri-iso-amyl phosphate and n-dodecane. AB - Tri-isoamyl phosphate (TiAP) has been proposed to be an alternative for tri-butyl phosphate (TBP) in the Plutonium Uranium Extraction (PUREX) process. Recently, we have successfully calibrated and tested all-atom optimized potentials for liquid simulations using Mulliken partial charges for pure TiAP, TBP, and dodecane by performing molecular dynamics (MD) simulation. It is of immense importance to extend this potential for the various molecular properties of TiAP and TiAP/n dodecane binary mixtures using MD simulation. Earlier, efforts were devoted to find out a suitable force field which can explain both structural and dynamical properties by empirical parameterization. Therefore, the present MD study reports the structural, dynamical, and thermodynamical properties with different mole fractions of TiAP-dodecane mixtures at the entire range of mole fraction of 0-1 employing our calibrated Mulliken embedded optimized potentials for liquid simulation (OPLS) force field. The calculated electric dipole moment of TiAP was seen to be almost unaffected by the TiAP concentration in the dodecane diluent. The calculated liquid densities of the TiAP-dodecane mixture are in good agreement with the experimental data. The mixture densities at different temperatures are also studied which was found to be reduced with temperature as expected. The plot of diffusivities for TiAP and dodecane against mole fraction in the binary mixture intersects at a composition in the range of 25%-30% of TiAP in dodecane, which is very much closer to the TBP/n-dodecane composition used in the PUREX process. The excess volume of mixing was found to be positive for the entire range of mole fraction and the excess enthalpy of mixing was shown to be endothermic for the TBP/n-dodecane mixture as well as TiAP/n-dodecane mixture as reported experimentally. The spatial pair correlation functions are evaluated between TiAP-TiAP and TiAP-dodecane molecules. Further, shear viscosity has been computed by performing the non-equilibrium molecular dynamics employing the periodic perturbation method. The calculated shear viscosity of the binary mixture is found to be in excellent agreement with the experimental values. The use of the newly calibrated OPLS force field embedding Mulliken charges is shown to be equally reliable in predicting the structural and dynamical properties for the mixture without incorporating any arbitrary scaling in the force field or Lennard-Jones parameters. Further, the present MD simulation results demonstrate that the Stokes-Einstein relation breaks down at the molecular level. The present methodology might be adopted to evaluate the liquid state properties of an aqueous-organic biphasic system, which is of great significance in the interfacial science and technology. PMID- 29471661 TI - Path integrals with higher order actions: Application to realistic chemical systems. AB - Quantum thermodynamic parameters can be determined using path integral Monte Carlo (PIMC) simulations. These simulations, however, become computationally demanding as the quantum nature of the system increases, although their efficiency can be improved by using higher order approximations to the thermal density matrix, specifically the action. Here we compare the standard, primitive approximation to the action (PA) and three higher order approximations, the Takahashi-Imada action (TIA), the Suzuki-Chin action (SCA) and the Chin action (CA). The resulting PIMC methods are applied to two realistic potential energy surfaces, for H2O and HCN-HNC, both of which are spectroscopically accurate and contain three-body interactions. We further numerically optimise, for each potential, the SCA parameter and the two free parameters in the CA, obtaining more significant improvements in efficiency than seen previously in the literature. For both H2O and HCN-HNC, accounting for all required potential and force evaluations, the optimised CA formalism is approximately twice as efficient as the TIA formalism and approximately an order of magnitude more efficient than the PA. The optimised SCA formalism shows similar efficiency gains to the CA for HCN-HNC but has similar efficiency to the TIA for H2O at low temperature. In H2O and HCN-HNC systems, the optimal value of the a1 CA parameter is approximately 13, corresponding to an equal weighting of all force terms in the thermal density matrix, and similar to previous studies, the optimal alpha parameter in the SCA was ~0.31. Importantly, poor choice of parameter significantly degrades the performance of the SCA and CA methods. In particular, for the CA, setting a1 = 0 is not efficient: the reduction in convergence efficiency is not offset by the lower number of force evaluations. We also find that the harmonic approximation to the CA parameters, whilst providing a fourth order approximation to the action, is not optimal for these realistic potentials: numerical optimisation leads to better approximate cancellation of the fifth order terms, with deviation between the harmonic and numerically optimised parameters more marked in the more quantum H2O system. This suggests that numerically optimising the CA or SCA parameters, which can be done at high temperature, will be important in fully realising the efficiency gains of these formalisms for realistic potentials. PMID- 29471662 TI - Pressure effect on micellization of non-ionic surfactant Triton X-100. AB - Micellar aggregates can be arranged in new types of conformational assemblies when they are isotropically compressed. Thus, the pressure effects in the underlying fundamental interactions leading to self-assembly of micellar aggregates can be represented by changes in the phase boundaries with increasing pressure. In this paper, we have employed molecular dynamics simulations to study the self-assembly of micelles composed of the non-ionic surfactant Triton X-100 at the atomic scale, monitoring the changes in the solvation dynamics when the micelles are subjected to a wide range of hydrostatic pressures. The computational molecular model was capable of self-assembling and forming a non ionic micelle, which subsequently was coupled to a high-pressure barostat producing a geometric transition of the micelle due to changes in the solvation dynamics. Accordingly, under a high pressure regime, the hydrogen bonds are redistributed, the water density is modified, and water acts as an unstructured liquid, capable of penetrating into the micelle. PMID- 29471663 TI - Quantum coherence in the reflection of above barrier wavepackets. AB - The quantum phenomenon of above barrier reflection is investigated from a time dependent perspective using Gaussian wavepackets. The transition path time distribution, which in principle is experimentally measurable, is used to study the mean flight times ?t?R and ?t?T associated with the reflection and the transmission over the barrier paying special attention to their dependence on the width of the barrier. Both flight times, and their difference Deltat, exhibit two distinct regimes depending on the ratio of the spatial width of the incident wavepacket and the length of the barrier. When the ratio is larger than unity, the reflection and transmission dynamics are coherent and dominated by the resonances above the barrier. The flight times ?t?R/T and the flight time difference Deltat oscillate as a function of the barrier width (almost in phase with the transmission probability). These oscillations reflect a momentum filtering effect related to the coherent superposition of the reflected and transmitted waves. For a ratio less than unity, the barrier reflection and transmission dynamics are incoherent and the oscillations are absent. The barrier width which separates the coherent and incoherent regimes is identified analytically. The oscillatory structure of the time difference Deltat as a function of the barrier width in the coherent regime is absent when considered in terms of the Wigner phase time delays for reflection and transmission. We conclude that the Wigner phase time does not correctly describe the temporal properties of above barrier reflection. We also find that the structure of the reflected and transmitted wavepackets depends on the coherence of the process. In the coherent regime, the wavepackets can have an overlapping peak structure, but the peaks are not fully resolved. In the incoherent regime, the wavepackets split in time into distinct separated Gaussian like waves, each one reflecting the number of times the wavepacket crosses the barrier region before exiting. A classical Wigner approximation, using classical trajectories which upon reaching an edge of the barrier are reflected or transmitted as if the edge was a step potential, is quantitative in the incoherent regime. The implications of the coherence observed on resonance reactive scattering are discussed. PMID- 29471664 TI - Anhydrosaccharides-A new class of the fragile plastic crystals. AB - In this paper, 1,6-anhydro-beta-D-glucopyranose (anhGLU), 1,6-anhydro-beta-D mannopyranose (anhMAN), and 1,6-anhydro-beta-D-galactopyranose (anhGAL), three new materials that form the Orientationally Disordered Crystal (ODIC) phase, have been thoroughly investigated using various experimental techniques. All measurements clearly indicated that these compounds possess a series of very interesting physical properties that are considerably different than those reported for ordinary plastic crystals. X-Ray diffraction investigations have revealed enormously long-range static correlations between molecules, reaching even 120 A. Moreover, dielectric studies showed that besides Freon 113, the investigated anhydrosaccharides are the most fragile systems that form the ODIC phase. Further analysis of Fourier transform infrared spectra indicated that such peculiar behavior of anhydrosaccharides might be closely related to multidirectional H-bonds of various strengths that most likely affect the number of available conformations, density states, and the potential barriers in the energy landscape of these compounds. This is consistent with the results from previous reports [L. C. Pardo, J. Chem. Phys. 124, 124911 (2006) and Th. Bauer et al., J Chem. Phys. 133, 144509 (2010)] showing that the higher fragility of Freon 112 as well as a mixture of 60% succinonitrile and 40% glutaronitrile (60SN-40GN) can be closely related to the enhanced conformational ability and additional disorder introduced by various substituents, which further make energy landscape more complex. Finally, by studying the properties of 2,3,4-tri-O-acetyl-1,6 anhydro-beta-D-glucopyranose (ac-anhGLU) it was found that besides the shape of the molecules, H-bonds or generally strong intermolecular interactions are extremely important parameters contributing to the ability to form the plastic phase. This is in line with current observations that in most cases the ODIC phase is created in highly interacting compounds. PMID- 29471665 TI - Communication: The electronic entropy of charged defect formation and its impact on thermochemical redox cycles. AB - The ideal material for solar thermochemical water splitting, which has yet to be discovered, must satisfy stringent conditions for the free energy of reduction, including, in particular, a sufficiently large positive contribution from the solid-state entropy. By inverting the commonly used relationship between defect formation energy and defect concentration, it is shown here that charged defect formation causes a large electronic entropy contribution manifesting itself as the temperature dependence of the Fermi level. This result is a general feature of charged defect formation and motivates new materials design principles for solar thermochemical hydrogen production. PMID- 29471666 TI - Rural-urban differences in exposure to adverse childhood experiences among South Carolina adults. AB - INTRODUCTION: Adverse childhood experiences (ACEs) are traumatic events that occur in a child's life between birth and 18 years. Exposure to one or more ACE has been linked to participation in risky health behaviors and the experience of chronic health conditions in adulthood. The risk for poor outcomes increases as the number of ACEs experienced increases. This research investigates rural-urban differences in exposure to ACEs using a sample from a representative southern US state, South Carolina. METHODS: Using data from the 2014-2015 South Carolina Behavioral Risk Factor Surveillance System (BRFSS) and residential rurality based on UICs, ACE exposure among South Carolina adults was tabulated by urban versus rural residence and selected other demographic characteristics. Using standard descriptive statistics, frequencies and proportions were calculated for each categorical variable. Multivariable regression modeling was used to examine the impact of residential rurality and selected sociodemographic characteristics on overall and specific types of ACE exposure. All analyses used survey sampling weights that accounted for the BRFSS sampling strategy. RESULTS: The analytic sample of 18 176 respondents comprised 15.9% rural residents. Top reported ACEs for both rural and urban residents were the same: parental divorce/separation, emotional abuse, and household substance use. Compared to urban residents, a higher proportion of rural respondents reported experiencing no ACEs (41.4% vs 38.3%, p<0.01). The prevalence of four or more ACEs in rural respondents was 15.0%; in comparison, 17.6% of urban respondents had four or more ACEs (p<0.01). In logistic regression predicting exposure to four or more ACEs and adjusting for sex, age, race/ethnicity, education, and income, rural respondents were less likely than urban respondents to report four or more ACEs (adjusted odds ratio 0.75, 95% confidence interval 0.74-0.75). CONCLUSIONS: Despite reporting less ACE exposure than urban counterparts, almost 60% of rural residents reported at least one ACE and 15% reported experiencing four or more ACEs. In contrast to urban residents, rural residents may experience more social connections within their families and communities, which may influence ACE exposure; however, care coordination, social support services, and access to health care are limited in rural areas. Thus, families in rural areas may be less equipped to mitigate and manage the effects of ACEs. Findings from this study thus suggest that interventions to prevent ACE exposure are just as needed in rural southern communities as they are in urban southern communities. Topics important for future research could include an examination of ACEs in rural communities in terms of individuals' health outcomes and their access to health care, as well as the role of protective factors. Programs and policies that assist in ACE prevention in rural areas are important to reducing these multigenerational threats to health and wellbeing. PMID- 29471667 TI - Review of differentiated approaches to antiretroviral therapy distribution. AB - In response to global trends of maximizing the number of patients receiving antiretroviral therapy (ART), this review summarizes literature describing differentiated models of ART distribution at facility and community levels in order to highlight promising strategies and identify evidence gaps. Databases and gray literature were searched, yielding thirteen final articles on differentiated ART distribution models supporting stable adult patients. Of these, seven articles focused on distribution at facility level and six at community level. Findings suggest that differentiated models of ART distribution contribute to higher retention, lower attrition, and less loss to follow-up (LTFU). These models also reduced patient wait time, travel costs, and time lost from work for drug pick-up. Facility- and community-level ART distribution models have the potential to extend treatment availability, enable improved access and adherence among people living with HIV (PLHIV), and facilitate retention in treatment and care. Gaps remain in understanding the desirability of these models for PLHIV, and the need for more information the negative and positive impacts of stigma, and identifying models to reach traditionally marginalized groups such as key populations and youth. Replicating differentiated care so efforts can reach more PLHIV will be critical to scaling these approaches across varying contexts. PMID- 29471668 TI - Explained and unexplained racial and regional inequality in obesity prevalence in the United States. AB - OBJECTIVE: There are substantial racial and regional disparities in obesity prevalence in the United States. This study partitioned the mean Body Mass Index (BMI) and obesity prevalence rate gaps between non-Hispanic blacks and non Hispanic whites into the portion attributable to observable obesity risk factors and the remaining portion attributable to unobservable factors at the national and the state levels in the United States (U.S.) in 2010. DESIGN: This study used a simulated micro-population dataset combining common information from the Behavioral Risk Factor Surveillance System and the U.S. Census data to obtain a reliable, large sample representing the adult populations at the national and state levels. It then applied a reweighting decomposition method to decompose the black-white mean BMI and obesity prevalence disparities at the national and state levels into the portion attributable to the differences in distribution of observable obesity risk factors and the remaining portion unexplainable with risk factors. RESULTS: We found that the observable differences in distribution of known obesity risk factors explain 18.5% of the mean BMI difference and 20.6% of obesity prevalence disparities between non-Hispanic blacks and non-Hispanic whites. There were substantial variations in how much the differences in distribution of known obesity risk factors can explain black-white gaps in mean BMI (-67.7% to 833.6%) and obesity prevalence (-278.5% to 340.3%) at the state level. CONCLUSION: The results from this study demonstrate that known obesity risk factors explain a small proportion of the racial, ethnic and between-state disparities in obesity prevalence in the United States. Future etiologic studies are required to further understand the causal factors underlying obesity and racial, ethnic and geographic disparities. PMID- 29471669 TI - Optimizing stress responses with reappraisal and mindset interventions: an integrated model. AB - BACKGROUND: The dominant perspective in society is that stress has negative consequences, and not surprisingly, the vast majority of interventions for coping with stress focus on reducing the frequency or severity of stressors. However, the effectiveness of stress attenuation is limited because it is often not possible to avoid stressors, and avoiding or minimizing stress can lead individuals to miss opportunities for performance and growth. Thus, during stressful situations, a more efficacious approach is to optimize stress responses (i.e., promote adaptive, approach-motivated responses). Objectives and Conclusions: In this review, we demonstrate how stress appraisals (e.g., [Jamieson, J. P., Nock, M. K., & Mendes, W. B. (2012). Mind over matter: reappraising arousal improves cardiovascular and cognitive responses to stress. Journal of Experimental Psychology: General, 141(3), 417-422. doi: 10.1037/a0025719 ]) and stress mindsets (e.g., [Crum, A. J., Salovey, P., & Achor, S. (2013). Rethinking stress: The role of mindsets in determining the stress response. Journal of Personality and Social Psychology, 104(4), 716-733. doi: 10.1037/a0031201 ]) can be used as regulatory tools to optimize stress responses, facilitate performance, and promote active coping. Respectively, these interventions invite individuals to (a) perceive stress responses as functional and adaptive, and (b) see the opportunity inherent in stress. We then propose a novel integration of reappraisal and mindset models to maximize the utility and effectiveness of stress optimization. Additionally, we discuss future directions with regard to how stress responses unfold over time and between people to impact outcomes in the domains of education, organizations, and clinical science.

AB - Background Detecting recurrence of glioma on magnetic resonance imaging (MRI) is getting more and more important, especially after administration of new anti tumor agent. However, it is still hard to identify. Purpose To examine the utility of intravoxel incoherent motion (IVIM) MRI and arterial spin labeling cerebral blood flow (ASL-CBF) for recurrent glioma after initiation of bevacizumab (BEV) treatment. Material and Methods Thirteen patients (7 men, 6 women; age range = 41-82 years) with glioma (high grade, n = 11; low grade, n = 2) were enrolled in the study. IVIM parameters including apparent diffusion coefficient (ADC), true diffusion coefficient (D), and perfusion fraction (f) were obtained with 14 different b-values. We identified tumor progression during BEV therapy by MRI monitoring consisting of diffusion-weighted imaging (DWI), fluid-attenuated inversion recovery (FLAIR) imaging, and contrast-enhanced T1 weighted (CE-T1W) imaging by measuring tumor area. We also measured each parameter of IVIM and ASL-CBF, and calculated relative ADC (rADC), relative D (rD), relative f (rf), and relative CBF (rCBF) by obtaining the ratio between each area and the contralateral cerebral white matter. We calculated the rate of change (Delta) by subtracting values from those from the preceding MRI study, and obtained Spearman's rank correlation coefficient (rs). Results Tumor progression was identified in nine patients (high grade, n = 7; low grade, n = 2). Negative correlations were identified between DeltarD and DeltaDWI area (rs = -0.583), and between DeltarD and DeltaCE-T1W imaging area (rs = -0.605). Conclusion Tumor progression after BEV treatment can be identified by decreasing rD.

AB - The aim of this study was to determine the prevalence of physical inactivity and whether it is associated with sociodemographic, lifestyle, clinical, anthropometric, and body composition variables in people living with HIV/AIDS (PLWHA). This study makes use of data from a cohort of 288 adults aged >=19 years, conducted between October 2009 and July 2011. The variables studied were sex, age, education, income, skin color, tobacco use, alcohol intake, body mass index, body fat percentage, waist circumference, and waist-hip ratio, length of HIV/AIDS diagnosis, use of antiretroviral therapy and length of its use, CD4, hypertension (HT) and diabetes mellitus. Physical inactivity was defined as a score below 600 metabolic equivalent minutes/week according to the International Physical Activity Questionnaire - Short Version. Poisson multiple regression was applied in the multivariate analysis with a significance level of 5%. The prevalence of physical inactivity was 44.1%. Education of <=4 years of study (prevalence ratio [PR]: 1.71) and HT (PR: 1.49) were associated with physical inactivity. Physical inactivity was highly prevalent in PLWHA and associated with low educational level and HT. We highlight the simultaneous association between two cardiometabolic risk factors, HT and physical inactivity. PMID- 29471671 TI - Cholesterol-enriched membrane microdomains are needed for insulin signaling and proliferation in hepatic cells. AB - Hepatocyte proliferation during liver regeneration is a well-coordinated process regulated by the activation of several growth factor receptors, including the insulin receptor (IR). The IR can be localized in part to cholesterol-enriched membrane microdomains, but the role of such domains in insulin-mediated events in hepatocytes is not known. We investigated whether partitioning of IRs into cholesterol-enriched membrane rafts is important for the mitogenic effects of insulin in the hepatic cells. IR and lipid rafts were labeled in HepG2 cells and primary rat hepatocytes. Membrane cholesterol was depleted in vitro with metyl beta-cyclodextrin (MbetaCD) and in vivo with lovastatin. Insulin-induced calcium (Ca2+) signals studies were examined in HepG2 cells and in freshly isolated rat hepatocytes as well as in whole liver in vivo by intravital confocal imaging. Liver regeneration was studied by 70% partial hepatectomy (PH), and hepatocyte proliferation was assessed by PCNA staining. A subpopulation of IR was found in membrane microdomains enriched in cholesterol. Depletion of cholesterol from plasma membrane resulted in redistribution of the IR along the cells, which was associated with impaired insulin-induced nuclear Ca2+ signals, a signaling event that regulates hepatocyte proliferation. Cholesterol depletion also led to ERK1/2 hyper-phosphorylation. Lovastatin administration to rats decreased hepatic cholesterol content, disrupted lipid rafts and decreased insulin-induced Ca2+ signaling in hepatocytes, and delayed liver regeneration after PH. Therefore, membrane cholesterol content and lipid rafts integrity showed to be important for the proliferative effects of insulin in hepatic cells. NEW & NOTEWORTHY One of insulin's actions is to stimulate liver regeneration. Here we show that a subpopulation of insulin receptors is in a specialized cholesterol-enriched region of the cell membrane and this subfraction is important for insulin's proliferative effects. PMID- 29471673 TI - Identifying Additional Risk Factors for Thrombosis and Pregnancy Morbidities Among Antiphospholipid Antibodies Carriers. AB - The evaluation of thrombotic and pregnancy risks associated with antiphospholipid antibodies (aPL)in individual patients without antiphospholipid syndrome (APS) clinical manifestation is challenging. Our aim is to identify additional risk factors or potential candidate "second hits" for APS clinical events in a large cohort of ethnically diverse aPL-positive patients. We included 219 consecutive aPL-positive patients who attended clinic at our institution. All patients had at least 1 persistent high titer (>=99 percentiles) aPL. Independent risk factors for thrombosis and pregnancy morbidities among patients with positive aPL were evaluated. When assessing risk factors associated with pregnancy morbidities, only female controls of reproductive age (age <=45) were used. Pearson chi2 analysis and multivariable logistic regression were used to evaluate correlation between different risk factors and clinical manifestations. Of the 219 aPL positive patients, 120 (54.8%) patients had criteria APS clinical manifestations and 99 patients did not. A total of 46.1% were Caucasian, 26.4% of African descent, 16.9% Hispanic, 1.8% Asian, and 8.7% were unspecified. Among traditional risk factors and signs of endothelial injury, only hypertension demonstrated an independent association with arterial thrombosis (odds ratio [OR] = 3.826, 95% confidence interval [CI]: 1.597-9.167, P = .0026), and lupus anticoagulant (LA) demonstrated an independent association with venous thrombosis (OR = 3.308, 95% CI: 1.544-7.085, P = .0021). None of the evaluated risk factors demonstrated a significant association with pregnancy morbidity. Hypertension is a potential predictor of arterial thrombosis and the presence of LA is a potential predictor of venous thrombosis in aPL-positive patients. PMID- 29471674 TI - Concomitant Versus Individual Administration of Antithrombin and Thrombomodulin for Sepsis-Induced Disseminated Intravascular Coagulation: A Nationwide Japanese Registry Study. AB - BACKGROUND: Antithrombin and recombinant human thrombomodulin (rhTM) are individually reported to improve survival in sepsis-induced disseminated intravascular coagulation (DIC). However, continuing controversy exists as to which agent is superior and whether concomitant therapy is superior to individual administration. METHODS: This post hoc analysis included adult patients with sepsis-induced DIC from a nationwide multicenter registry database in Japan. We categorized patients into 4 groups: patients who received (1) individual administration of antithrombin, (2) individual administration of rhTM, (3) both, and (4) neither. In-hospital mortality was compared between every 2 groups among the 4 groups by Cox proportional hazards model adjusted with propensity scores. RESULTS: In total, 1432 patients with sepsis-induced DIC were included. Although both antithrombin and rhTM were associated better outcome compared with no anticoagulants, mortality benefits were similar between each individual anticoagulant. Similarly, no significant difference in mortality was detected between individual administrations and concomitant therapy. CONCLUSION: Antithrombin and rhTM might have comparable efficacy in reducing mortality in patients with sepsis; however, concomitant therapy appeared to offer no additional survival benefit. PMID- 29471675 TI - Alterations in nucleotide-binding oligomerization domain-2 expression, pathway activation, and cytokine production in Yao syndrome. AB - Yao syndrome (YAOS) is a systemic autoinflammatory disease (SAID), formerly termed nucleotide-binding oligomerization domain-2 (NOD2)-associated autoinflammatory disease. Due to the recent identification of YAOS, the molecular mechanisms underlying its disease pathogenesis are unclear. With specific NOD2 variants as characteristic genotypic features of YAOS, our study examined NOD2 expression, transcript splicing, signaling pathway activation, and cytokine profiles in peripheral blood mononuclear cells (PBMCs) from 10 YAOS patients and six healthy individuals. All participants were genotyped for NOD2 variants; all YAOS patients were heterozygous for the NOD2 IVS8+158 variant (IVS8+158) and four patients also carried a concurrent NOD2 R702W variant (IVS8+158/R702W haplotype). Resembling other SAIDs, plasma levels of TNFalpha, IL-1beta, IL-6, IFNgamma, and S100A12 were unaltered in YAOS patients. Intron-8 splicing of NOD2 transcripts was unaffected by carriage of NOD2 IVS8+158. However, NOD2 transcript level and basal p38 mitogen-activated protein kinase (MAPK) activity were significantly elevated in PBMCs from IVS8+158 YAOS patients. Moreover, these patients' cells had elevated basal IL-6 secretion that was enhanced by muramyl dipeptide (MDP) stimulation. Tocilizumab treatment of a YAOS IVS8+158 patient resulted in marked clinical improvement. In contrast, MDP-stimulated NF-kappaB activity was uniquely suppressed in haplotype IVS8+158/R702W patients, as was TNFalpha secretion. Our study demonstrates for the first time that NOD2 expression and pathway activation are aberrant in YAOS, and specific NOD2 genotypes result in distinct NOD2 expression and cytokine profiles. These findings may also help select therapeutic strategies in the future. PMID- 29471676 TI - Results and challenges of immune checkpoint inhibitors in colorectal cancer. AB - INTRODUCTION: Colorectal cancer (CRC) is the third most commonly diagnosed cancer worldwide and clinical outcome has improved substantially during the last two decades with targeted therapies. The immune system has a major role in cancers, especially the CD8 + T cells specific to tumor antigens. However, tumors can escape immune response by different mechanisms including upregulation of inhibitory immune checkpoint receptors, such as well-known Programmed cell Death protein-1 (PD-1)/Programmed cell Death Ligand 1 (PD-L1) interaction, leading CD8 + T cells to a state of anergy. Immunotherapy, with the so-called immune checkpoint inhibitors (CPIs), has recently been approved in treatment of multiple cancers due to its prolonged disease control and acceptable toxicities. The recent groundbreaking success involving anti-PD-1 CPIs in metastatic CRC with deficient mismatch repair system (dMMR) is promising, with several trials ongoing. Major challenges are ahead in order to determine how, when and for which patients we should use these CPIs in CRC. Areas covered: This review highlights some promises and challenges concerning personalized immunotherapy in CRC. First results and ongoing breakthrough trials are presented. The crucial role of biomarkers in selecting patient is also discussed. Expert opinion: As of now, dMMR and POLE mutations (DNA polymerase epsilon) with ultramutator phenotype are the most powerful predictive biomarkers of CPI efficacy. The most challenging issue is pMMR mCRC and determination of how to convert a 'nonimmunogenic' neoplasm into an 'immunogenic' neoplasm, a combination of CPIs with radiation or MEK inhibitor probably being the most relevant strategy. Next-generation sequencing (NGS) assays to quantify mutational load could be more reliable predictive biomarkers of CPIs efficacy than PD-L1 expression or immune scores. PMID- 29471677 TI - Association between coping strategies, social support, and depression and anxiety symptoms among rural Ugandan women living with HIV/AIDS. AB - Poor mental health detrimentally affects quality of life among women living with HIV/AIDS. An improved understanding of how coping and social support relate to depression and anxiety in this population can facilitate the design and implementation of appropriate mental health treatment and support services. Secondary analysis was conducted on baseline data from 288 HIV-positive women enrolled in a parenting intervention in Uganda. Depression and anxiety symptoms, social support, and coping were assessed with the Hopkins Symptom Checklist and adapted versions of the Multidimensional Scale for Perceived Social Support and Ways of Coping Questionnaire. General linear regression models were used to estimate associations between coping and mental health. Based on report of elevated symptoms, approximately 10% of women were categorized as having clinically-relevant depression or anxiety. Emotion-focused (EF: p < .001) and problem-focused (PF: p = .01) coping were associated with more depressive symptoms while greater family support (EF: p = .002; PF: p = .003) was associated with fewer depression symptoms. More anxiety symptoms were associated with reporting both coping strategies (EF: p < .001; PF: p = .02) and higher community support (EF&PF: p = .01). The cross-sectional nature of the study limits our ability to rule out the role of reverse causation in the significant relationship between coping and mental health. Findings do suggest that high family support can be protective against depression and anxiety symptoms among women living with HIV.

PMID- 29471679 TI - ARISE: A Phase 3 randomized trial of erenumab for episodic migraine. AB - Background Calcitonin gene-related peptide plays an important role in migraine pathophysiology. Erenumab, a human monoclonal antibody that inhibits the calcitonin gene-related peptide receptor, is being evaluated for migraine prevention. Methods In this randomized, double-blind, placebo-controlled, phase 3 study, 577 adults with episodic migraine were randomized to placebo or 70 mg erenumab; 570 patients were included in efficacy analyses. Primary endpoint was change in monthly migraine days. Secondary endpoints were >=50% reduction in monthly migraine days, change in acute migraine-specific medication treatment days, and >=5-point reduction in Physical Impairment and Impact on Everyday Activities domain scores measured by the Migraine Physical Function Impact Diary. All endpoints assessed change from baseline at month 3. Results Patients receiving erenumab experienced -2.9 days change in monthly migraine days, compared with -1.8 days for placebo, least-squares mean (95% CI) treatment difference of -1.0 (-1.6, -0.5) ( p < 0.001). A >= 50% reduction in monthly migraine days was achieved by 39.7% (erenumab) and 29.5% (placebo) of patients (OR:1.59 (95% CI: 1.12, 2.27) ( p = 0.010). Migraine-specific medication treatment days were reduced by -1.2 (erenumab) and -0.6 (placebo) days, a treatment difference of -0.6 (-1.0, -0.2) ( p = 0.002). The >=5-point reduction rates in Migraine Physical Function Impact Diary - Physical Impairment were 33.0% and 27.1% (OR:1.33 (0.92, 1.90) ( p = 0.13) and in Migraine Physical Function Impact Diary - Everyday Activities were 40.4% and 35.8% (OR:1.22 (0.87, 1.71) ( p = 0.26). Safety and adverse event profiles of erenumab were similar to placebo. Most frequent adverse events were upper respiratory tract infection, injection site pain, and nasopharyngitis. Conclusions As a preventive treatment of episodic migraine, erenumab at a dosage of 70 mg monthly significantly reduced migraine frequency and acute migraine-specific medication use.

PMID- 29471680 TI - Proteomic profiling of extracellular vesicles released from vascular smooth muscle cells during initiation of phosphate-induced mineralization. AB - : Purpose/Aim: Elevated serum phosphate is one of the major factors contributing to vascular calcification. Studies suggested that extracellular vesicles released from vascular smooth muscle cells significantly contribute to the initiation and progression of this pathology. Recently, we have demonstrated that elevated phosphate stimulates release of extracellular vesicles from osteogenic cells at the initiation of the mineralization process. Here, we used MOVAS cell line as an in vitro model of vascular calcification to examine whether vascular smooth muscle cells respond to high phosphate levels in a similar way and increase formation of extracellular vesicles. MATERIALS AND METHODS: Vesicles residing in extracellular matrix as well as vesicles released to culture medium were evaluated by nanoparticle tracking analyses. In addition, using mass spectrometry and protein profiling, protein composition of extracellular vesicles released by MOVAS cells under standard growth conditions and upon exposure to high phosphate was compared. RESULTS: Significant increase of the number of extracellular vesicles was detected after 72 h of exposure of cells to high phosphate. Elevated phosphate levels also affected protein composition of extracellular vesicles released from MOVAS cells. Finally, the comparative analyses of proteins in extracellular vesicles isolated from extracellular matrix and from conditioned medium identified significant differences in protein composition in these two groups of extracellular vesicles. CONCLUSIONS: Results of this study demonstrate that exposure of MOVAS cells to high phosphate levels stimulates the release of extracellular vesicles and changes their protein composition. PMID- 29471681 TI - rA1M-035, a Physicochemically Improved Human Recombinant alpha1-Microglobulin, Has Therapeutic Effects in Rhabdomyolysis-Induced Acute Kidney Injury. AB - AIMS: Human alpha1-microglobulin (A1M) is an endogenous reductase and radical- and heme-binding protein with physiological antioxidant protective functions. Recombinant human A1M (rA1M) has been shown to have therapeutic properties in animal models of preeclampsia, a pregnancy disease associated with oxidative stress. Recombinant A1M, however, lacks glycosylation, and shows lower solubility and stability than A1M purified from human plasma. The aims of this work were to (i) use site-directed mutagenesis to improve the physicochemical properties of rA1M, (ii) demonstrate that the physicochemically improved rA1M displays full in vitro cell protective effects as recombinant wild-type A1M (rA1M-wt), and (iii) show its therapeutic potential in vivo against acute kidney injury (AKI), another disease associated with oxidative stress. RESULTS: A novel recombinant A1M variant (rA1M-035) with three amino acid substitutions was constructed, successfully expressed, and purified. rA1M-035 had improved solubility and stability compared with rA1M-wt, and showed intact in vitro heme-binding, reductase, antioxidation, and cell protective activities. Both rA1M-035 and rA1M wt showed, for the first time, potential in vivo protective effects on kidneys using a mouse rhabdomyolysis glycerol injection model of AKI. INNOVATION: A novel recombinant A1M-variant, rA1M-035, was engineered. This protein showed improved solubility and stability compared with rA1M-wt, full in vitro functional activity, and potential protection against AKI in an in vivo rhabdomyolysis mouse model. CONCLUSION: The new rA1M-035 is a better drug candidate than rA1M-wt for treatment of AKI and preeclampsia in human patients. Antioxid. Redox Signal. 00, 000-000. PMID- 29471682 TI - The role of spousal relationships in fibromyalgia patients' quality of life. AB - Fibromyalgia (FM) is a chronic pain syndrome that includes debilitating symptoms such as widespread pain and tenderness, fatigue, and poor physical functioning. Research has shown FM patients' choice of coping style and relationship quality with their spouse can impact their mental quality of life (QoL), but no known study has examined the protective nature of relationship quality and coping behaviors on both patient physical and mental QoL in the context of chronic pain. We examined 204 patients with FM on the (a) roles of coping styles and relationship quality on patient quality of life, and (b) moderating effect of relationship quality on the association between negative coping style and patient QoL. A series of multiple regressions found patients' coping styles were not significantly associated with physical QoL, but were significantly associated with mental QoL. Patients' relationship quality with their spouse was significantly associated with mental QoL, but not physical QoL and no significant interactions with negative coping style were found. Our results emphasize the importance of coping styles and relationship quality between patients and their spouses in the context of chronic pain. Clinicians can incorporate the patient's relationship as part of a more holistic approach to care and improving outcomes.

AB - INTRODUCTION: Bronchial thermoplasty is a licensed non-pharmacological treatment for severe asthma. Area covered: This article considers evidence for the efficacy and safety of bronchial thermoplasty from clinical trials and observational studies in clinical practice. Its place in the management of severe asthma, predictors of response and mechanisms of action are reviewed. Expert commentary: Bronchial thermoplasty improves quality of life and reduces exacerbations in moderate to severe asthma. Morbidity from asthma is increased during treatment. Overall, patients treated in clinical practice have worse baseline characteristics and comparable clinical outcomes to trial data. Follow-up studies provide reassurance on long-term safety. Despite some progress, future research needs to investigate uncertainties about predictors of response, mechanism of action and place in management of asthma. PMID- 29471686 TI - Comparison of HbA1c and glycated albumin as a control marker for newborn complications in diabetic women in a multicentre study in Japan (Japan glycated albumin study group: study 2). AB - Background To clarify the relationship between glycated haemoglobin and glycated albumin concentrations during pregnancy with neonatal outcomes, a multicentre study was conducted by the Japanese Society of Diabetes and Pregnancy. Methods A total of 136 patients (type 1: n = 47, type 2: n = 89) who enrolled in the study were diagnosed based on the Japanese Diabetes Society diagnostic criteria for diabetes mellitus. Thresholds for glycated haemoglobin and glycated albumin were set at 5.8% and 15.8%, respectively, as the upper limits of the reference interval in pregnant women. Result Random plasma glucose decreased linearly, and reached the reference interval at 40 weeks. Glycated albumin concentrations also decreased in the same manner. But glycated haemoglobin concentrations were out of the reference interval during the study. The frequency of the neonatal complications did not show significant differences between the glycated haemoglobin ?5.8% group and the glycated haemoglobin <5.8% group. On the other hand, the frequency of neonatal complications showed higher tendency of neonatal complications in the incidence of polycythaemia ( P = 0.094) and heavy-for-date ( P = 0.071) in the glycated albumin ?15.8% group compared with the glycated albumin <15.8 group. The respiratory disorder in type 1 diabetes was significantly higher than type 2 diabetes. Conclusions For the treatment of pregnant women with diabetes, glycated albumin would be a better marker than glycated haemoglobin. However, glycated albumin is also affected by obesity and albumin, and it is desirable to make a comprehensive judgment with glycated haemoglobin, random plasma glucose and other glycaemic index. PMID- 29471687 TI - Neutrophil CD64 - A potential biomarker in patients with complicated intra abdominal infections? - A literature review. AB - Complicated intra-abdominal infections (cIaIs) respresent a serious cause of morbidity and mortality. Early diagnosis and well-timed treatment can improve patients' outcome, whereas the delay in management often result in rapid progression to circulatory collapse, multiple organ failure, and death. Neutrophil CD64 antigen expression has been studied for several years as infectious and sepsis biomarker and has several characteristics that make it good for clinical employment. It has been suggested to be predictive of positive bacterial cultures and a useful test for management of sepsis and other significant bacterial infections. Our review concluded that the neutrophil CD64 expression could be a promising and meaningful biomarker in patients with cIaIs. It shows good potential for evaluating the severity of the disease and could give information about the outcome. However, more large studies should be performed before using it in clinical practice. PMID- 29471688 TI - Plasmid-mediated quinolone resistance determinants in Enterobacteriaceae from urine clinical samples. AB - Plasmid-mediated quinolone resistance (PMQR) determinants including, qnrA, qnrB, qnrC, qnrD, qnrS, aac(6')-Ib-cr, oqxAB, and qepA, were investigated in 214 Enterobacteriaceae strains from urine clinical samples. Antimicrobial susceptibility testing for ciprofloxacin, ceftriaxone, and imipenem was performed by broth microdilution method. All strains were screened for PMQR genes by PCR. Virulence determinants, namely afa, pap, pil, sfa/foc, and kpsMT of eight Escherichia coli strains proven positive for at least one qnr gene, were investigated by PCR. All of the eight investigated strains carried the pil gene, showing that P fimbria is a common virulence determinant among qnr positive E. coli. Out of 214 tested strains, 38 yielded any PMQR determinant, altogether 45 genes were detected namely, 6 qnrA, 1 qnrB, 2 qnrD and 8 qnrS, 9 aac(6')-Ib-cr, and 19 oqxAB; however, neither qepA nor qnrC were detected. Notably, 18 Klebsiella spp., harbored oqxAB, nine E. coli were positive for qnrS and two Morganella morganii yielded qnrD resistance determinant. In this study, we demonstrated 17.7% prevalence of PMQR-positive Enterobacteriaceae and first reported qnrD-resistance determinant in Hungary. Altogether, 25 PMQR-positive strains were susceptible or low-level resistant to ciprofloxacin with minimum inhibitory concentration (MIC) between 0.06 and 1 mg/L, suggesting that prevalence of PMQR determinants is underestimated and screening among clinical isolates exhibiting reduced susceptibility is necessary. Fluoroquinolone resistance breakpoints of Enterobacteriaceae were revised in 2017 by European Committee of Antimicrobial Susceptibility Testing indicating ciprofloxacin susceptibility only until 0.25 mg/L MIC value. PMID- 29471689 TI - Mediation of inflammatory ascites formation induced by macromolecules in mice. AB - The first 60-min phase of inflammatory ascites formation was studied by intraperitoneally (i.p.) administered macromolecular inducers: yeast cell wall zymosan binds to specific macrophage receptors, polyethyleneimine (PEI) and concanavalin A (ConA), produces non-covalent cross-links on the surface of various cells, while lambda-carrageenan may function as a contact activator. Depletion of peritoneal macrophages was performed by overnight pretreatment with diphtheria toxin in transgenic mice, resulting in a significant (p < 0.01) decrease in the induced formation of ascitic fluid. It was shown that induced ascites is mediated partly (PEI, ConA, and carrageenan) or completely (zymosan) by peritoneal macrophages. Inhibition of prostanoid synthesis with indomethacine or of the kallikrein/bradykinin system with aprotinin also produced a significant (p < 0.01) but incomplete inhibition. A slight additivity occurred between the different inhibitory effects. In another series of experiments, the i.p. administration of bradykinin (without a macromolecular inducer) also produced marked ascites, which was not affected by macrophage depletion. The origin of the macrophage-independent part of the induced ascites is best explained by the deformation of the mesothelial cell surface, resulting in signal transfer to the underlying endothelium and the passage of ascitic fluid in the opposite direction. The soluble mediators are represented by prostanoids, bradykinin and other, unidentified agonists. PMID- 29471690 TI - Genetic support of carbapenemases in double carbapenemase producer Klebsiella pneumoniae isolated in the Arabian Peninsula. AB - Enterobacteriaceae co-producing NDM- and OXA-48-type carbapenemases were encountered in higher frequency in the United Arab Emirates (UAE) than in the neighboring countries in our earlier study. The aim of this investigation was to characterize the seven double carbapenemase producer Klebsiella pneumoniae found in the region to assess factors contributing to their emergence. Three K. pneumoniae ST14 isolated in the UAE harboring blaNDM-1 on IncHI1b and blaOXA-232 on IncColE plasmids were clonally related. Furthermore, two K. pneumoniae from the UAE, ABC106 and ABC137 belonged to ST307 and ST1318, respectively. ABC106 carried blaNDM-1 on IncHI1b, and blaOXA-162 on IncL/M plasmids, whereas ABC137 possessed blaNDM-1 on IncX3 and blaOXA-48 on IncL/M plasmids. The double carbapenemase-producing K. pneumoniae from Oman (OMABC109) and Saudi Arabia (SA54) belonged to ST11 and ST152, respectively. OMABC109 harbored blaNDM-1 on an IncHI1b plasmid highly similar to the NDM-plasmid of ABC106 and carried a chromosomally coded blaOXA-181 located on Tn2013. SA54 possessed a blaNDM-1 on an IncFIb/FII plasmid and a blaOXA-48 on an IncL/M plasmid. Based on these findings, clonal spread and horizontal transfer of carbapenemase genes located on transposons or self-transmissible plasmids contributed equally to the emergence of double carbapenemase-producing Enterobacteriaceae in the region. PMID- 29471691 TI - Streptococcus pneumoniae quorum sensing and biofilm formation are affected by Thymus daenensis, Satureja hortensis, and Origanum vulgare essential oils. AB - The aim of this study was to investigate the effect of Thymus daenensis L., Satureja hortensis L., and Origanum vulgare L. essential oils (EOs) on the planktonic growth, biofilm formation, quorum sensing (QS), and competence system (CS) of Streptococcus pneumoniae. The anti-biofilm activity of EOs was determined by Microtiter-Plate Test (MtP) and scanning electron microscope (SEM). The QS and CS inhibitory activities were determined on the pre-grown biofilm by gene expression analysis using quantitative real-time RT-PCR. Using gas chromatography mass spectrometry analysis, the major components of the tested EOs were detected. The MtP and SEM detected a significant inhibitory effect of the three EOs on biofilm formation at sub-minimum inhibitory concentrations (MICs). The most anti biofilm activity was seen for T. daenensis. LuxS and pfs genes (genes involved in QS) downregulated the following treatment with MIC/2 of Thymus and Satureja EOs. Thymol, carvacrol, p-cymene, pulegone, and 1,8-cineole were the major components of the tested EOs. The used EOs seem to be good candidates for preventing biofilm formation and subsequent colonization of S. pneumoniae. This study introduced T. daenensis and S. hortensis as new anti-biofilm and QS inhibitor agents with a natural origin. PMID- 29471692 TI - Bacterial diversity in soils of different Hungarian karst areas. AB - Karst areas have great environmental importance as sources of subsurface water and often maintain very sensitive ecosystems. In recent years, increasing number of microbiological studies focused on the bacterial communities of karst soils. In this study, diversity examinations on two distinct Hungarian karst areas, Aggtelek and Tapolca, were performed using parallel cultivation and molecular cloning methods. The phylogenetic affiliation of bacterial strains and molecular clones was determined based on their 16S rRNA gene sequences. Bacterial isolates were identified as members of the phyla Actinobacteria, Firmicutes, Proteobacteria, and Bacteroidetes. Besides the taxa identified by cultivation, members of the phyla Chloroflexi, Cyanobacteria, Acidobacteria, Verrucomicrobia, and Gemmatimonadetes were detected by the cloning. The difference in the composition of soil bacterial communities was related to geographic locations and soil types. Both the highest and the lowest bacterial diversities were detected in samples from Aggtelek National Park, characterized by Leptic Luvisol and Rendzic Leptosol soil types. The difference in the composition of bacterial communities between Rendzic Leptosol and Leptic Phaeozem soil types at Tapolca could be the result of human impacts.

AB - Today, to replace the antibacterial targets to overcome antibiotic resistance, toxin-antitoxin (TA) system is noticeable, where the unstable antitoxin neutralizes the stable toxin and protects the bacteria against the toxic effects. The presence and expression of TA genes in clinical and non-clinical strains of Staphylococcus epidermidis were investigated in this study. After identification of three TA pairs (mazEF, sam, and phd-doc) via existing databases (earlier, there has been no information in the case of S. epidermidis isolates), the presence and expression of these pairs were investigated by PCR and q-PCR, respectively. We detected three TA modules in all antibiotic sensitive and resistant isolates. In addition, q-PCR analysis revealed that the transcripts were produced from the three TA modules. This study showed the significant prevalence of these systems in pathogenic bacteria and they were equally found in both oxacillin-resistant and oxacillin-susceptible bacteria. The high prevalence of three systems can make them suitable as potential targets for antibiotic therapy.

AB - This study provides a comprehensive microbiological survey of three drinking water networks applying different water treatment processes. Variability of microbial communities was assessed by cultivation-based [nitrifying, denitrifying most probable number (MPN) heterotrophic plate count] and sequence-aided terminal restriction fragment length polymorphism (T-RFLP) analysis. The effect of microbial community composition on nitrifying MPN values was revealed. The non treated well water samples showed remarkable differences to their corresponding distribution systems regarding low plate count, nitrifying MPN, and the composition of microbial communities, which increased and changed, respectively, in distribution systems. Environmental factors, such as pH, total inorganic nitrogen content (ammonium and nitrite concentration), and chlorine dioxide treatment had effect on microbial community compositions. The revealed heterogeneous nitrifying population achieved remarkable nitrification, which occurred at low ammonium concentration (14-51 MUM) and slightly alkaline pH 7.7 7.9 in chlorine dioxide disinfected water networks. No change was observed in nitrification-generated nitrate concentration, although nitrate-reducing (and denitrifying) bacteria were present with low MPN and characterized by sequence aided T-RFLP. The community structures of water samples partially changed in nitrifying enrichments and had influence on the generated nitrifying, especially nitrite-oxidizing MPN regarding the facilitated growth of nitrate-reducing bacteria and even methanogenic archaea beside ammonia-oxidizing microorganisms and nitrite-oxidizing bacteria.

PMID- 29471696 TI - The recombinant fusion protein CFP10-ESAT6-dIFN has protective effect against tuberculosis in guinea pigs. AB - Development of effective vaccine candidates against tuberculosis is currently the most important challenge in the prevention of this disease since the BCG vaccine fails to guarantee a lifelong protection, while any other approved vaccine with better efficiency is still absent. The protective effect of the recombinant fusion protein ESAT6-CFP10-dIFN produced in a prokaryotic expression system (Escherichia coli) has been assessed in a guinea pig model of acute tuberculosis. The tested antigen comprises the Mycobacterium tuberculosis (Mtb) proteins ESAT6 and CFP10 as well as modified human gamma-interferon (dIFN) for boosting the immune response. Double intradermal immunization of animals with the tested fusion protein (2 * 0.5 MUg) induces a protective effect against subsequent Mtb infection. The immunized animals do not develop the symptoms of acute tuberculosis and their body weight gain was five times more as compared with the non-immunized-infected animals. The animal group immunized with this dose of antigen displays the minimum morphological changes in the internal organs and insignificant inflammatory lesions in the liver tissue, which complies with a decrease in the bacterial load in the spleen and average Mtb counts in macrophages. PMID- 29471697 TI - First report of Acanthamoeba genotype T8 human keratitis. AB - Acanthamoeba has a worldwide distribution in the environment and it is capable of causing a painful sight-threatening disease of the cornea designated as Acanthamoeba keratitis (AK). Nowadays, the cases of AK have surged all over the world along with its disease burden due to increasing use of contact lenses used not only for optical correction but also for cosmetic purposes. In our present work, epithelial abrasion of a 27-year-old female soft contact lens wearer with keratitis was examined. Genotype identification was carried out with a real-time fluorescence resonance energy transfer polymerase chain reaction (PCR) assay based on sequence analysis of the 18S rRNA gene. Genotyping allowed the identification of a T8 group isolate. The analysis confirmed the importance of a complete diagnostic protocol, including a PCR assay, for the clinical diagnosis of AK from human samples. Acanthamoeba T8 should be considered as potential causative organism in keratitis in human. PMID- 29471698 TI - Gender differences in acute coronary syndromes: focus on the women with ACS without an obstructing culprit lesion. AB - INTRODUCTION: The etiologies of acute coronary syndromes (ACS) in women expand beyond the traditional paradigm of obstructive epicardial atherosclerotic disease and plaque rupture. Fundamental differences in pathobiology and presentation can partially explain the gender disparity in ACS diagnosis and management, but there is also much we do not know about the spectrum of coronary artery disease in women. Areas covered: This review seeks to explain some key differences between men and women in terms of risk factors, pathophysiology, and clinical presentations, as well as identify areas where more data are needed, focusing on women presenting with ACS but without a culprit lesion to explain their presentation. Literature search was undertaken with PubMed and Google Scholar. Expert commentary: Women with acute coronary syndromes but without plaque rupture or obstructive epicardial atherosclerosis can be difficult to diagnose and manage. Improving care in this underdiagnosed and undertreated population will require early identification of at risk patients, development of better diagnostic strategies, and standardized implementation of guideline-based therapies. PMID- 29471699 TI - Atezolizumab for the treatment of colorectal cancer: the latest evidence and clinical potential. AB - INTRODUCTION: Atezolizumab is a fully humanized, engineered monoclonal antibody that specifically targets PD-L1, key molecule in the cancer-immunity pathway. Atezolizumab is currently approved for the treatment of metastatic non-small-cell lung cancer and advanced urothelial carcinomas. Areas covered: In this review, we will present the available data supporting the efficacy of atezolizumab for the treatment of metastatic colorectal cancer (mCRC). We will also provide an update on the ongoing/future clinical trials evaluating the role of atezolizumab for the treatment of CRC in different settings (alone or in combination with other checkpoint inhibitors and/or targeted therapies). So far, a small subgroup of mCRC (those with deficiency in mismatch repair - dMMR) appears to benefit significantly from checkpoint inhibitors. As expected, further research is needed to develop biomarkers, effective therapeutic strategies and novel combinations to overcome immune escape resistance and achieve better responses with minimal toxicities. Expert opinion: Interim analyses from ongoing early-phase studies in mCRC have shown encouraging activity of atezolizumab in combination with chemotherapy and/or targeted therapies, especially with MEK inhibitor cobimetinib. Within the next few years, this PD-L1 checkpoint inhibitor will likely be included as one of the treatment options for CRC, at least for patients with dMMR.

PMID- 29471701 TI - Repairing the corneal epithelium using limbal stem cells or alternative cell based therapies. AB - INTRODUCTION: The corneal epithelium is maintained by limbal stem cells (LSCs) that reside in the basal epithelial layer of the tissue surrounding the cornea termed the limbus. Loss of LSCs results in limbal stem cell deficiency (LSCD) that can cause severe visual impairment. Patients with partial LSCD may respond to conservative therapies designed to rehabilitate the remaining LSCs. However, if these conservative approaches fail or, if complete loss of LSCs occurs, transplantation of LSCs or their alternatives is the only option. While a number of clinical studies utilizing diverse surgical and cell culture techniques have shown favorable results, a universal cure for LSCD is still not available. Knowledge of the potential risks and benefits of current approaches, and development of new technologies, is essential for further improvement of LSCD therapies. Areas covered: This review focuses on cell-based LSCD treatment approaches ranging from current available clinical therapies to preclinical studies of novel promising applications. Expert opinion: Improved understanding of LSC identity and development of LSC expansion methods will influence the evolution of successful LSCD therapies. Ultimately, future controlled clinical studies enabling direct comparison of the diverse employed approaches will help to identify the most effective treatment strategies. PMID- 29471702 TI - Children With ADHD Symptoms: Who Can Do Without Specialized Mental Health Care? AB - OBJECTIVE: A new Dutch Child and Youth Act should reduce specialized mental health care for children with symptoms of ADHD. Characteristics of children referred to a specialized ADHD clinic are explored to give direction to this intention. METHOD: Data of 261 children who underwent a multidisciplinary best practice evaluation (including rating scales, and demographic, psychological, and somatic findings) were analyzed. Univariable and multivariable logistic regression models were used to find predictive variables for the need of specialized mental health care. RESULTS: Collected data were heterogeneous. (Sub)clinical total scores on the Teacher Report Form (TRF) and Child Behavior Checklist (CBCL) were predictive variables for specialized mental health care. Also children with divorced parents were more often referred to specialized care. CONCLUSION: (Sub)clinical scores on the CBCL and TRF increased the need for specialized care, but comprehensive assessment of every child with ADHD symptoms was necessary to differentiate between levels of care. PMID- 29471703 TI - Maternal second trimester blood levels of selected heavy metals in pregnancies complicated with neural tube defects. AB - PURPOSE: Neural tube defects (NTDs) are the most common malformations of the central nervous system (CNS). There is continuing research for the identification of risk factors and interventions for prevention of NTDs. The aim of this study was to investigate the maternal second trimester blood levels of selected heavy metals namely, arsenic (As), cadmium (Cd), mercury (Hg), manganese (Mn), nickel (Ni), and lead (Pb) and their possible relation with the occurrence of NTDs. METHODS: Twenty-one healthy second trimester pregnant women with fetuses affected with NTD (cases) were matched with 21 healthy pregnant women with unaffected fetuses (controls) with respect to age, body mass index (BMI), and gestational age. Maternal blood levels of heavy metals were measured after an overnight fasting period. RESULTS: No significant differences were observed in terms of maternal blood levels of As, Cd, Hg, and Ni between NTD-affected and unaffected pregnancies. The blood Pb and Mn levels were found to be higher in pregnant women with a fetus affected with NTD when compared with pregnant women with unaffected fetuses (for Pb, in cases 12.3 +/- 5.5 ug/L, in controls 7.8 +/- 2.4 ug/L; for Mn in cases 3.6 +/- 1.4 ug/L, in controls 2.4 +/- 1.0 ug/L, p < .05). CONCLUSIONS: High maternal second trimester blood levels of Pb and Mn during pregnancy are associated with NTDs in the newborn. PMID- 29471704 TI - Flow-diverter stents for endovascular management of non-fetal posterior communicating artery aneurysms-analysis on aneurysm occlusion, vessel patency, and patient outcome. AB - Background Use of flow-diversion technology in the treatment of incidental and recanalized posterior communicating artery (PComA) aneurysms. Methods Patients treated with the Pipeline embolization device (PED) for PComA aneurysms were identified and included in our retrospective analysis. We evaluated aneurysm characteristics, modified Rankin Scale score (mRS) on admission, angiography follow-up, and patient clinical outcome at discharge, at three to nine months, and at 12-18 months. Results We included 56 patients with a mean age of 56 years. Median mRS on admission was 0. All aneurysms involved the PComA and were either new findings or found to have shown recanalization at angiography follow-up from previous coil embolization or surgical clipping. Intraprocedural device foreshortening was observed in one case requiring additional placement of a self expanding stent. One intraprocedural aneurysm rupture occurred because of a broken distal wire. This patient had an mRS of 4 after the procedure. Three- to nine-month and 12- to 18-month follow-up angiography showed near complete or complete aneurysm occlusion in most cases. Minimal to mild intimal hyperplasia was seen in five cases at three to nine months. PComA patency over time showed 29 of 46 initially patent vessels still patent at six months. Thirteen and seven PComAs showed progressive decrease in flow at three to nine months and 12-18 months, respectively. Median mRS remained 0 for all patients at three- to nine month and 12- to 18-month follow-up. Conclusions Our preliminary results show that flow-diversion technology is an effective and safe treatment option. Larger studies with long-term follow-up are needed to validate our promising results. PMID- 29471705 TI - Differences in outcomes between cesarean section in the second versus the first stages of labor. AB - OBJECTIVE: We aimed to compare maternal morbidity and mortality of cesarean sections (CS) in the second versus first stage of labor. STUDY DESIGN: Retrospective study of all CS at a single, university-affiliated medical center, between January 2010 and December 2014. Eligibility was limited to term, singleton pregnancies with cephalic presentation. Maternal outcomes of second stage CS were compared to those of first-stage CS. The primary outcome was defined as estimated blood loss >1000 ml. RESULTS: Overall, 1004 women met the inclusion criteria, of which 290 (29%) had a second-stage CS and 714 (71%) had a first-stage CS. Women in the second-stage CS group had a higher nulliparity and hypertensive disorders rates and a lower rate of previous CS. Second-stage CS was associated with more than double the rate of estimated blood loss >1000 ml (9.7% versus 3.8%, p<.001), and more prone to unintentional uterine incision extension, uterine atony, hemoglobin decrease >2 g/l and antibiotic treatment for suspected endometritis. In a multivariable logistic regression model, second-stage CS was found to be independently associated with unintentional uterine incision extension (OR 6.8, 95% CI 4.1-11.2), uterine atony (OR 3.3, 95% CI 1.4-8.0) and antibiotic treatment for suspected endometritis (OR 2.6, 95% CI 1.4-5.1), but not with excessive blood loss (OR 1.5, 95% CI 0.8-2.8). Additionally, failed assisted vaginal delivery prior to second-stage CS was not associated with a higher rate of complications. CONCLUSION: Second-stage CS is associated with higher rates of adverse maternal outcomes, mainly unintentional uterine incision extension, uterine atony, and suspected endometritis. PMID- 29471707 TI - Delivery during extracorporeal membrane oxygenation (ECMO) support of pregnant woman with severe respiratory distress syndrome caused by influenza: a case report and review of the literature. AB - OBJECTIVE: To report a case of labour induction during extracorporeal membrane oxygenation (ECMO) support in a patient with acute respiratory distress syndrome (ARDS) caused by influenza and review of the literature. METHODS: Case report and the literature search of all English articles on delivery while on ECMO in patients with ARDS caused by influenza. RESULTS: A 25-year-old pregnant woman was initiated with ECMO due to severe ARDS caused by influenza A (H1N1) virus. When the patient had symptoms of colporrhagia and uterine contractions, the medical team decided to start labour induction while on ECMO. There were in total five case reports identified. Maternal oxygenation was improved after delivery and ECMO was successfully discontinued. CONCLUSIONS: Maternal oxygenation was improved after delivery, which may be beneficial to reduce the duration of ECMO. Caesarean section (CS) may be the most used mode and labour induction could be another option. The procedure should be performed by an experienced ECMO team, cooperating with the obstetrician, anaesthesiologist, and ICU doctors. PMID- 29471706 TI - "Where Did This [PrEP] Come From?" African American Mother/Daughter Perceptions Related to Adolescent Preexposure Prophylaxis (PrEP) Utilization and Clinical Trial Participation. AB - Despite the demonstrated effectiveness of preexposure prophylaxis (PrEP) to reduce incident HIV infections, PrEP's potential as an HIV prevention strategy for adolescent populations is unknown. This study assessed perceptions of adolescent PrEP use and clinical trial participation among African American women and their adolescent daughters. We conducted focus group discussions with 15 African American mother/daughter pairs ( N = 30). Findings suggest a general lack of PrEP awareness, favorable attitudes toward adolescent PrEP use, altruistic attitudes regarding research participation among daughters, and less favorable attitudes toward adolescent clinical trial participation among mothers. Study findings have the potential to inform strategies that provide equitable access to HIV scientific advances among African American women and girls and promote informed parent-child research decision making. PMID- 29471708 TI - Visual attention mechanisms in happiness versus trustworthiness processing of facial expressions. AB - A happy facial expression makes a person look (more) trustworthy. Do perceptions of happiness and trustworthiness rely on the same face regions and visual attention processes? In an eye-tracking study, eye movements and fixations were recorded while participants judged the un/happiness or the un/trustworthiness of dynamic facial expressions in which the eyes and/or the mouth unfolded from neutral to happy or vice versa. A smiling mouth and happy eyes enhanced perceived happiness and trustworthiness similarly, with a greater contribution of the smile relative to the eyes. This comparable judgement output for happiness and trustworthiness was reached through shared as well as distinct attentional mechanisms: (a) entry times and (b) initial fixation thresholds for each face region were equivalent for both judgements, thereby revealing the same attentional orienting in happiness and trustworthiness processing. However, (c) greater and (d) longer fixation density for the mouth region in the happiness task, and for the eye region in the trustworthiness task, demonstrated different selective attentional engagement. Relatedly, (e) mean fixation duration across face regions was longer in the trustworthiness task, thus showing increased attentional intensity or processing effort. PMID- 29471709 TI - Trilinguals' language switching: A strategic and flexible account. AB - The goal of this study was to determine how trilinguals select the language they intend to use in a language switching context. Two accounts are examined: (a) a language-specific account, according to which language selection considers the activation level of words of the intended language only (i.e., language co activation without language competition), and (b) a language non-specific account, where activated words from both the intended and non-intended languages compete for selection (i.e., language co-activation with language competition). Results showed that, in both groups, all three languages competed for selection and that selection was achieved by inhibiting the currently non-relevant languages. Moreover, extending findings from previous research, the study reveals that, in both Experiments 1 and 2, the amount of inhibition was influenced not only by language proficiency but also by the typological similarity between languages. Overall, the study shows that language switching performance can be accounted for by a strategic and flexible inhibitory account. In particular, the controlling system is "strategic" in the sense that it aims at preventing potential conflicting situations, such as typological closeness between languages, and it is "flexible" in that it adjusts languages' activation levels, depending on the conflict to be solved. PMID- 29471710 TI - Predicting our own and others' future preferences: The role of social distance. AB - People underestimate how much their preferences will change in the future, a phenomenon sometimes referred to as a "presentism bias." Recently, we found that this presentism bias is attenuated when thinking about the preferences of other people. The aim of this study was to investigate whether predicting future preferences also differs depending on the level of social distance between self and other. A total of 67 participants completed a perspective-taking task in which they were required to think about their own preferences, those of a generic peer, and those of a close other both now and in the future. They were also asked to consider the preferences of an older adult now. Participants predicted less change between their current and future preferences than between the current and future preferences of a generic peer. Predicted change in preferences for a close other were similar, but not identical, to those made for the self. When considering relevant future preferences, participants predicted less change for themselves than for their close others and less change for close others than for generic peers. In other words, as social distance increases, the presentism bias decreases. Interestingly, participants estimated that both they and their peers would not change so much that they become similar to current older adults. Simulating the future perspectives of a generic peer or, even better, the current perspectives of an older adult may thus result in improved long-term decision making, as it may enable a more realistic estimation of the magnitude of likely changes in the future. PMID- 29471711 TI - Enhancing Autonomy in Biobank Decisions: Too Much of a Good Thing? AB - The opportunity to receive individual research results (IRRs) in accordance with personal preferences may incentivize biobank participation and maximize perceived benefit. This trial investigated the relationship between parents' preferences and intent to participate (ITP) in biobank research utilizing their child's genetic information. We randomized parents of pediatric patients to four hypothetical biobanks, one of which employed a preference-setting model for return of results regarding their child. ITP was highest among those desiring all types of IRRs (93.3%) and decreased as participants became increasingly selective with their preferences ( p < .0001). We demonstrated that most parents would participate in a biobank that allows for preference setting; however, those who set preferences to receive a narrower set of IRRs are less likely to participate. PMID- 29471712 TI - Memory and conceptual learning of relevant and non-relevant items in item-method directed forgetting. AB - The present research investigates the fate of non-target information when people are trying to either intentionally memorise or forget target information. By using an object-based attentional manipulation within a directed forgetting paradigm (item-method), we show a directed forgetting effect (DFE, i.e., better memory for to-be-remembered (TBR) than for to-be-forgotten (TBF) items) for items that participants are explicitly instructed to attend but not for irrelevant items that happen to be part of the context. Alongside the classic DFE, we investigate how the category of the attended and unattended items are learned. The results obtained in three experiments, show that people can successfully learn only the category of the TBR attended items and that the DFE extends to new items that are related to the old TBR and TBF items (an effect that we call conceptual DFE). These results give us new insight about how TBR and TBF items are processed and conceptually learned. PMID- 29471713 TI - Silk fibroin/chitosan thin film promotes osteogenic and adipogenic differentiation of rat bone marrow-derived mesenchymal stem cells. AB - As a biodegradable polymer thin film, silk fibroin/chitosan composite film overcomes the defects of pure silk fibroin and chitosan films, respectively, and shows remarkable biocompatibility, appropriate hydrophilicity and mechanical properties. Silk fibroin/chitosan thin film can be used not only as metal implant coating for bone injury repair, but also as tissue engineering scaffold for skin, cornea, adipose, and other soft tissue injury repair. However, the biocompatibility of silk fibroin/chitosan thin film for mesenchymal stem cells, a kind of important seed cell of tissue engineering and regenerative medicine, is rarely reported. In this study, silk fibroin/chitosan film was prepared by solvent casting method, and the rat bone marrow-derived mesenchymal stem cells were cultured on the silk fibroin/chitosan thin film. Osteogenic and adipogenic differentiation of rat bone marrow-derived mesenchymal stem cells were induced, respectively. The proliferation ability, osteogenic and adipogenic differentiation abilities of rat bone marrow-derived mesenchymal stem cells were systematically compared between silk fibroin/chitosan thin film and polystyrene tissue culture plates. The results showed that silk fibroin/chitosan thin film not only provided a comparable environment for the growth and proliferation of rat bone marrow-derived mesenchymal stem cells but also promoted their osteogenic and adipogenic differentiation. This work provided information of rat bone marrow derived mesenchymal stem cells behavior on silk fibroin/chitosan thin film and extended the application of silk fibroin/chitosan thin film. Based on the results, we suggested that the silk fibroin/chitosan thin film could be a promising material for tissue engineering of bone, cartilage, adipose, and skin. PMID- 29471714 TI - The Bodily Illusion in Adverse Conditions: Virtual Arm Ownership During Visuomotor Mismatch. AB - Classically, body ownership illusions are triggered by cross-modal synchronous stimulations, and hampered by multisensory inconsistencies. Nonetheless, the boundaries of such illusions have been proven to be highly plastic. In this immersive virtual reality study, we explored whether it is possible to induce a sense of body ownership over a virtual body part during visuomotor inconsistencies, with or without the aid of concomitant visuo-tactile stimulations. From a first-person perspective, participants watched a virtual tube moving or an avatar's arm moving, with or without concomitant synchronous visuo-tactile stimulations on their hand. Three different virtual arm/tube speeds were also investigated, while all participants kept their real arms still. The subjective reports show that synchronous visuo-tactile stimulations effectively counteract the effect of visuomotor inconsistencies, but at slow arm movements, a feeling of body ownership might be successfully induced even without concomitant multisensory correspondences. Possible therapeutical implications of these findings are discussed. PMID- 29471715 TI - The effect of acute dissociation on the electrophysiological properties of rat dorsal root ganglion neurons. AB - The acutely dissociated neurons from the dorsal root ganglia (DRGs) are extensively used. The effects of acute dissociation on the properties of these neurons are, however, not clear. In this study, the action potentials (APs) were recorded from both acutely dissociated and in vivo identified DRG neurons with patch clamp and sharp electrode recording techniques, respectively. We found that acute dissociation slowed both the depolarizing and repolarizing rate of APs, and elongated the AP duration (APD). The lower recording temperature presented in the acutely dissociated neurons contributed to about 10% of these differences. The major contributor of these differences was possibly modulation of the mRNA expression especially those of the ion channels, as suggested by our observation that acute dissociation significantly reduced the mRNA abundance of Nav1.6-1.9. In conclusion, acute dissociation altered the electrophysiological properties of the DRG neurons; the disrupted gene-expression pattern may contribute to this effect. PMID- 29471716 TI - Age-related differences in emotion matching are limited to low intensity expressions. AB - Multi-label tasks confound age differences in perceptual and cognitive processes. We examined age differences in emotion perception with a technique that did not require verbal labels. Participants matched the emotion expressed by a target to two comparison stimuli, one neutral and one emotional. Angry, disgusted, fearful, happy, and sad facial expressions of varying intensity were used. Although older adults took longer to respond than younger adults, younger adults only outmatched older adults for the lowest intensity disgust and fear expressions. Some participants also completed an identity matching task in which target stimuli were matched on personal identity instead of emotion. Although irrelevant to the judgment, expressed emotion still created interference. All participants were less accurate when the apparent difference in expressive intensity of the matched stimuli was large, suggesting that salient emotion cues increased difficulty of identity matching. Age differences in emotion perception were limited to very low intensity expressions. PMID- 29471717 TI - Differential Response in Novel Stem Cell Niches of the Brain after Cervical Spinal Cord Injury and Traumatic Brain Injury. AB - Populations of neural stem cells (NSCs) reside in a number of defined niches in the adult central nervous system (CNS) where they continually give rise to mature cell types throughout life, including newly born neurons. In addition to the prototypical niches of the subventricular zone (SVZ) and subgranular zone (SGZ) of the hippocampal dentate gyrus, novel stem cell niches that are also neurogenic have recently been identified in multiple midline structures, including circumventricular organs (CVOs) of the brain. These resident NSCs serve as a homeostatic source of new neurons and glial cells under intact physiological conditions. Importantly, they may also have the potential for reparative processes in pathological states such as traumatic spinal cord injury (SCI) and traumatic brain injury (TBI). As the response in these novel CVO stem cell niches has been characterized after stroke but not following SCI or TBI, we quantitatively assessed cell proliferation and the neuronal and glial lineage fate of resident NSCs in three CVO nuclei-area postrema (AP), median eminence (ME), and subfornical organ (SFO) -in rat models of cervical contusion-type SCI and controlled cortical impact (CCI)-induced TBI. Using bromodeoxyuridine (BrdU) labeling of proliferating cells, we find that TBI significantly enhanced proliferation in AP, ME, and SFO, whereas cervical SCI had no effects at early or chronic time-points post-injury. In addition, SCI did not alter NSC differentiation profile into doublecortin-positive neuroblasts, GFAP-expressing astrocytes, or Olig2-labeled cells of the oligodendrocyte lineage within AP, ME, or SFO at both time-points. In contrast, CCI induced a pronounced increase in Sox2- and doublecortin-labeled cells in the AP and Iba1-labeled microglia in the SFO. Lastly, plasma derived from CCI animals significantly increased NSC expansion in an in vitro neurosphere assay, whereas plasma from SCI animals did not exert such an effect, suggesting that signaling factors present in blood may be relevant to stimulating CVO niches after CNS injury and may explain the differential in vivo effects of SCI and TBI on the novel stem cell niches. PMID- 29471719 TI - An fMRI study of loneliness in younger and older adults. AB - Loneliness, the subjective experience of social isolation, may reflect, in part, underlying neural processing of social signals. Aging may exacerbate loneliness due to decreased social networks and increased social isolation, or it may reduce loneliness due to preferential attentional processing of positive information and increased interactions with emotionally close partners. Here, we conducted a functional magnetic resonance imaging (fMRI) study of loneliness in younger (N = 50, 26 female, Mage = 20.4) and older (N = 49, 30 female, Mage = 62.9) adults. Compared to younger adults, older adults were less lonely and dwelled longer on faces, regardless of valence. Previous studies in younger adults found that loneliness was negatively correlated with ventral striatal (VS) activation to pleasant social pictures of strangers yet positively correlated with VS activation to faces of close others. In the present study, we observed no association between loneliness and VS activation to social pictures of strangers in either age group. Further, unlike previous studies, we observed no association between social network size and amygdala activation to social stimuli. Additional research is needed to examine the effect of loneliness and social network size on neural processing of different dimensions of social stimuli. PMID- 29471720 TI - Idols as Sunshine or Road Signs: Comparing Absorption-Addiction Idolatry With Identification-Emulation Idolatry. AB - This study seeks to contrast absorption-addiction idolatry and identification emulation idolatry. Whereas absorption-addiction idolatry progresses from entertainment/socializing to personalizing and obsession about the idol, identification-emulation idolatry unfolds in terms of identification, attachment, romantization, idealization, and consumption about the idol or his or her derivatives. Based on a sample of 1310 secondary school and university students in Hong Kong, the study verified the original factor model composed of five first order identification-emulation idolatry and three first-order absorption addiction idolatry factors, with the latter more predictable by fans' club membership. PMID- 29471718 TI - The VraSR regulatory system contributes to virulence in Streptococcus suis via resistance to innate immune defenses. AB - Streptococcus suis is a highly invasive pathogen that can cause sepsis and meningitis in pigs and humans. However, we have limited understanding of the mechanisms S. suis uses to evade innate immunity. To investigate the involvement of the two-component signal transduction system of S. suis in host immune defense, we examined the expression of 15 response regulators of S. suis following stimulation with polymorphonuclear leukocytes (PMNs). We found that several response regulators were significantly up-regulated including vraR. Thus, we constructed an isogenic deletion mutant of vraSR genes in S. suis and demonstrated VraSR promotes both bacterial survival in human blood and resistance to human PMN-mediated killing. The VraSR mutant was more susceptible to phagocytosis by human PMNs and had greater sensitivity to oxidant and lysozyme than wild-type S. suis. Furthermore, in vitro findings and in vivo evidence from a mouse infection model together strongly demonstrate that DeltavraSR had greatly attenuated virulence compared with wild-type S. suis. Collectively, our data reveal that VraSR is a critical regulatory system that contributes to the survival of S. suis and its ability to defend against host innate immunity. PMID- 29471721 TI - Evaluation of Epithelial Lining Fluid Concentration of Amikacin in Critically Ill Patients With Ventilator-Associated Pneumonia. AB - INTRODUCTION: Classically, aminoglycosides are known to have low penetration into the lung tissue. So far, no study has been conducted on human adult patients to evaluate amikacin concentration in epithelial lining fluid (ELF) of the alveoli. Therefore, convincing data are not available from the perspective of pharmacokinetics to support the fact that a dosage of 20 mg/kg of amikacin is sufficient to treat patients with ventilator-associated pneumonia (VAP). METHOD: This was a pilot study of amikacin concentration measurement in the alveolar site of action in critically ill adult patients with VAP who required aminoglycoside therapy. A dose of 20 mg/kg of amikacin was administered over a 30-minute infusion. The serum concentrations of amikacin were evaluated in the first, second, fourth, and sixth hours. However, the ELF concentration of amikacin was evaluated in the second hour with the help of bronchoalveolar lavage sampling technique. RESULTS: A total number of 8 patients was included in the study. The mean (SD) administered dose was 20 (0.9) mg/kg. The mean (SD) peak plasma concentration of amikacin was 59.6 (23) mg/L, with the volume of distribution of 0.36 (0.13)L/kg. The amikacin concentration in ELF was successfully measured in 7 patients (6.3) mg/L. The lung tissue penetration of the drug was described as alveolar percentage, proportional to both the first- and second-hour plasma concentrations, with a mean (SD) of 10.1% (8.4%) and 18% (16.7%), respectively. CONCLUSION: To our knowledge, the current study is the first that investigates whether standard doses of amikacin may lead to sufficient alveolar concentration of the drug. The results show that administration of amikacin in doses of 20 mg/kg in critically ill patients with VAP may not provide sufficient concentrations in ELF. PMID- 29471722 TI - Outcomes and Resource Use Among Overweight and Obese Children With Sepsis in the Pediatric Intensive Care Unit. AB - OBJECTIVE: To evaluate the effect of overweight and obesity on outcomes and resource use among patients with sepsis in the pediatric intensive care unit (PICU). DESIGN: Retrospective analysis of clinical characteristics, resource use, and mortality among children 0 to 20 years of age admitted to the C.S. MottChildren's Hospital PICU (University of Michigan) between January 2009 and December 2015, with a diagnostic code for sepsis at admission (based on International Classification of Diseases, Ninth Revision- Clinical Modification codes) and with weight and height measurements at PICU admission. MEASUREMENTS AND MAIN RESULTS: A total of 454 participants met the inclusion criteria. Seventy six were categorized as underweight (body mass index [BMI] percentile <5th) and were excluded, which left a final sample size of 378 participants. Children with a BMI >5th and <85th percentiles for age were categorized as normal weight and those with a BMI >85th percentile as overweight/obese. After descriptive and bivariate analyses, multivariate regression methods were used to assess the independent effect of obesity status on mortality and the use of PICU technology after adjustment for patient age and illness severity at admission. Of the 378 patients studied, 41.3% were overweight/obese. There was no difference in microbiologic etiology of sepsis ( P = .36), median PICU length of stay in days (5.4 vs 5.6; P = .61), or PICU mortality (6.4% vs 7.2%; P = .76) by weight status. The use of specialized PICU technology including extracorporeal membrane oxygenation (odds ratio [OR]: 2.77, 95% confidence interval [CI]:1.13-6.79) and continuous renal replacement therapy (OR: 4.58, 95% CI: 1.16-18.0) was higher among overweight/obese patients, compared with normal weight patients. CONCLUSIONS: Although PICU mortality and length of stay were similar for obese overweight patients and normal weight critically ill children with sepsis, there was significantly higher use of specialized organ-supportive technology among obese patients, likely indicating higher occurrence of multiple organ dysfunction.

AB - Interstitial fluid (ISF) has recently garnered interest as a biological fluid that could be used as an alternate to blood for biomedical applications, diagnosis, and therapy. ISF extraction techniques are promising because they are less invasive and less painful than venipuncture. ISF is an alternative, incompletely characterized source of physiological data. Here, we describe a novel method of ISF extraction in rats, using microneedle arrays, which provides volumes of ISF that are sufficient for downstream analysis techniques such as proteomics, genomics, and extracellular vesicle purification and analysis. This method is potentially less invasive than previously reported techniques. The limited invasiveness and larger volumes of extracted ISF afforded by this microneedle-assisted ISF extraction method provide a technique that is less stressful and more humane to laboratory animals, while also allowing for a reduction in the numbers of animals needed to acquire sufficient volumes of ISF for biomedical analysis and application. PMID- 29471724 TI - Existential loneliness: An attempt at an analysis of the concept and the phenomenon. AB - BACKGROUND: According to ethical guidelines, healthcare professionals should be able to provide care that allows for the patients' values, customs and beliefs, and the existential issues that are communicated through them. One widely discussed issue is existential loneliness. However, much of the debate dealing with existential loneliness concludes that both the phenomenon and the concept are quite vague. AIM: To clarify what constitutes existential loneliness, and to describe its lived experiences. A further aim was to provide a definition of existential loneliness that can function as a tool for identifying the phenomenon and for differentiating it from other kinds of loneliness. METHOD: A literature review including theoretical and empirical studies. Different search strategies were used to gather the articles included in the study. The analysis of the empirical studies had an interpretative approach. The articles were also analysed with the aim of providing a definition of existential loneliness. This was done by means of criteria such as language, uniqueness, theory and usefulness. This study is not empirical and does therefore not require an ethics review. RESULTS: The analysis resulted in two main characteristics. The first one was perceiving oneself as inherently separated (disconnected) from others and from the universe. The second one brings out emotional aspects of EL, such as isolation, alienation, emptiness and a feeling of being abandoned. The empirical findings were divided into two categories: experiences of EL and circumstances in which EL arises. A definition of EL is also suggested, based on the two main characteristics identified. CONCLUSION: In order to meet patients' needs, it is an ethical duty for healthcare staff to be able to recognise experiences of EL, that is, to communicate with the patients about these experiences in an appropriate manner. This in turn demands knowledge about existential issues and skills to deal with them. PMID- 29471725 TI - Dignity from the nurses' and older patients' perspective: A qualitative literature review. AB - INTRODUCTION: Dignity is one of the most important values sensitively perceived by patients in nursing care. Older patients have been identified as having a high risk of losing their dignity in institutional care. To promote optimum nursing care, a deeper insight into the problem of older patients' dignity is needed. AIM: The aim was to identify, analyse and synthesise the qualitative evidence of dignity views and factors affecting it from the nurses' and older patients' perspective in the context of nursing care and to compare synthesised finding from the both perspective. METHODS: A literature review of qualitative evidence was chosen as a study design. The ENTREQ statement was implemented to enhance transparency. The CASP - Qualitative checklist and the thematic synthesis for synthesised findings were used. The electronic databases Academic Search Complete, CINAHL, Health Source: Nursing/Academic Edition, MEDLINE and PROQUEST were used to gather information for qualitative studies. RESULTS: A total of 306 papers were retrieved. Fourteen qualitative studies met the inclusion criteria and were included in the review after methodological quality assessment using CASP. Four main themes of dignity from nurses' perspective were synthesised: seeing the patient as a unique person, communication and privacy, involving the patient, and working culture and environment. From the patients' perspective, six main themes were synthesised: autonomy and control, privacy, relationships, care and comfort, communication and identity. The comparison shows that the key difference is that older patients highlighted the theme relationships and nurses underlined the theme working culture and environment. CONCLUSION: The model structures of the older patients' dignity from both the nurses' and patients' perspectives support the idea of a multidimensional structure of human dignity. The resulting model might be used in a nursing self-reflection, in the management of the institutions providing all-day care for the older people and in the education and practice. PMID- 29471726 TI - Exploring dual disclosures for men who have sex with men in Mpumalanga, South Africa: a report from the field. AB - We explored to whom rural men who have sex with men (MSM) disclose their sexual identity and HIV status in Mpumalanga, South Africa. Participants were recruited using a modified snowball sampling method in order to complete a questionnaire. Descriptive and logistic regression analyses were conducted. There were 47 participants of whom 22 self-reported as HIV-positive. Most participants disclosed their sexuality and HIV status to immediate family members and gay identified friends. We found that the longer someone had identified as MSM, the more likely they were to be HIV-positive and not go to clinic. Education and employment modified these findings. This study presents a broader picture of MSM in this rural African setting: that they do disclose their sexuality and HIV status to others in their community. However, more research is needed to develop these measures. We need to assess how long participants identify as MSM, how long they have been HIV-positive, and to whom they have disclosed these aspects of their lives to inform HIV prevention and treatment interventions for MSM in rural settings. PMID- 29471727 TI - Variations in Cigarette Smoking and Quit Attempts by Health Insurance Among US Adults in 41 States and 2 Jurisdictions, 2014. AB - OBJECTIVES: Information on the impact of health insurance on smoking and quit attempts at the state level is limited. We examined the state-specific prevalence of cigarette smoking and past-year quit attempts among adults aged 18-64 by health insurance and other individual- and state-level factors. METHODS: We used data from 41 states, the District of Columbia, and Puerto Rico, the jurisdictions that administered the Health Care Access module of the 2014 Behavioral Risk Factor Surveillance System. Data on quit attempts included current smokers with a past-year quit attempt and former smokers who quit during the past year. RESULTS: Overall, smoking prevalence ranged from 14.6% among those with private insurance to 34.7% among Medicaid enrollees, and past-year quit-attempt prevalence ranged from 66.4% among the uninsured to 71.5% among Medicaid enrollees. By insurance group, differences in the prevalence of state-specific past-year quit attempts ranged from 15 to 26 percentage points. Regardless of insurance type, people who were non-Hispanic white and had lower education levels were less likely to attempt quitting than were Hispanic people, non-Hispanic black people, and adults with more than a high school education. CONCLUSIONS: We found disparities in smoking and quit attempts by insurance status and state. Opportunities exist to increase access to cessation treatments through comprehensive state tobacco control programs and improved cessation insurance coverage, coupled with promotion of covered cessation treatments.

AB - Haploid cells facilitate genetic screening of recessive mutations for a single set of chromosomes. Haploid embryonic stem cells (haESCs) have been achieved in several species and widely utilized in genetic screens. The fact that haESCs undergo substantial diploidization during differentiation has limited the screening to other haploid cell types. In this study, we report a method to establish haploid neural stem cells (haNSCs) by selection for a Pax6 reporter. We inserted a green fluorescence protein (GFP) marker gene by homologous recombination into the Pax6 locus of an haESC line. GFP-positive haploid cells could be sorted and further cultured in the NSC medium for more than 30 passages. The established haNSCs expressed neural lineage markers and could differentiate into neurons, oligodendroglia, and astrocytes. Our study shows the feasibility of deriving haploid proliferative somatic cell lines using a genetically encoded reporter that suggest a system for genetic screening of neural and retinal development. PMID- 29471730 TI - Perceptions of why Malawians engage in concurrent sexual partnerships among a select population of radio listeners: findings from an exploratory study. AB - Concurrent sexual partnerships have been identified as a potential driver in the HIV epidemic in Southern Africa. This study utilised an innovative approach to explore perceptions of why Malawians may engage in these relationships, and their suggestions for reducing the practice among a select population of radio listeners. Using radio listener feedback in the form of text messages, we analysed approximately 1 000 text messages sent by individuals who listened to a reality radio programme that included real stories, told by Malawians, on topics related to HIV/AIDS. Listeners suggested that lack of satisfaction with one's partner was the overarching reason why individuals had concurrent sexual partnerships. Within the context of lack of satisfaction, listeners cited alcohol use, poor communication and gendered norms as factors related to satisfaction. Listeners suggested that couple communication could increase satisfaction, which, in turn, could reduce concurrent sexual partnerships. Prevention efforts should consider how to utilise couple communication to improve satisfaction as an approach to reduce HIV risk in Southern Africa. PMID- 29471731 TI - The role of pelvis-thorax coupling in controlling within-golf club swing speed. AB - Pelvis-thorax coordination has been recognised to be associated with swing speed. Increasing angular separation between the pelvis and thorax has been thought to initiate the stretch shortening cycle and lead to increased clubhead speed. The purpose of this study was to determine whether pelvis-thorax coupling played a significant role in regulating clubhead speed, in a group of low-handicap golfers (mean handicap = 4.1). Sixteen participants played shots to target distances determined based on their typical 5- and 6-iron shot distances. Half the difference between median 5- and 6-iron distance for each participant was used to create three swing effort conditions: "minus", "norm", and "plus". Ten shots were played under each swing effort condition using both the 5-iron and 6-iron, resulting in six shot categories and 60 shots per participant. No significant differences were found for X-factor for club or swing effort. X-factor stretch showed significant differences for club and swing effort. Continuous relative phase (CRP) results mainly showed evidence of the stretch shortening cycle in the downswing and that it was more pronounced late in the downswing as swing effort increased. Substantial inter-individual CRP variability demonstrated the need for individual analyses when investigating coordination in the golf swing. PMID- 29471733 TI - The influence of lotteries on employees' workplace HIV testing behaviour. AB - The aim of the study was to understand how lottery incentives influenced the HIV counselling and testing (HCT) behaviour and behaviour intention of shop-floor workers who participated in a workplace HCT campaign initiative in two companies in the Nelson Mandela Bay municipality, South Africa. A post-test only quasi experimental approach was used. The data were first collected, using a self administered cross-sectional survey instrument, among the control group (n = 88) followed by the experimental group (n = 110) after the advent of HIV testing and lotteries was announced. HIV testing behaviour data were collected on the days of the HIV testing events. The theory of planned behaviour (TPB) was used as guiding theory. Principal component analysis (PCA), t- and chi-square tests, and logistic regression were conducted to analyse the data. A significant increase in the mean scores of the experimental as compared to the control condition for the subjective norm's construct (t = -3.55, p < 0.001) and HIV testing behaviour intention (chi2 = 12.35, p < 0.001) was measured following the announcement of lottery incentives. The constructs of TPB explained 40% of the variance in HCT behaviour intention (R2 = 0.40). The strongest predictor of behaviour intention was the subjective norm (B = 0.435 and p < 0.001), followed by the attitudinal component (B = 0.323 and p = 0.040). The announcement of lotteries made shop floor workers develop a stronger intention to participate in workplace HIV testing through anticipation of stronger social support and encouragement. It was not possible to link behaviour intention to behaviour due to missing data. The findings point to the importance of providing workers with an opportunity to openly discuss HIV testing thus allowing mitigation of HIV stigma and discrimination and permitting HIV testing to become socially sanctioned and seen as part of a collective effort. PMID- 29471732 TI - Large Animal Models of an In Vivo Bioreactor for Engineering Vascularized Bone. AB - Reconstruction of large skeletal defects is challenging due to the requirement for large volumes of donor tissue and the often complex surgical procedures. Tissue engineering has the potential to serve as a new source of tissue for bone reconstruction, but current techniques are often limited in regards to the size and complexity of tissue that can be formed. Building tissue using an in vivo bioreactor approach may enable the production of appropriate amounts of specialized tissue, while reducing issues of donor site morbidity and infection. Large animals are required to screen and optimize new strategies for growing clinically appropriate volumes of tissues in vivo. In this article, we review both ovine and porcine models that serve as models of the technique proposed for clinical engineering of bone tissue in vivo. Recent findings are discussed with these systems, as well as description of next steps required for using these models, to develop clinically applicable tissue engineering applications. PMID- 29471734 TI - Probing light chain mutation effects on thrombin via molecular dynamics simulations and machine learning. AB - Thrombin is a key component for chemotherapeutic and antithrombotic therapy development. As the physiologic and pathologic roles of the light chain still remain vague, here, we continue previous efforts to understand the impacts of the disease-associated single deletion of LYS9 in the light chain. By combining supervised and unsupervised machine learning methodologies and more traditional structural analyses on data from 10 MUs molecular dynamics simulations, we show that the conformational ensemble of the DeltaK9 mutant is significantly perturbed. Our analyses consistently indicate that LYS9 deletion destabilizes both the catalytic cleft and regulatory functional regions and result in some conformational changes that occur in tens to hundreds of nanosecond scaled motions. We also reveal that the two forms of thrombin each prefer a distinct binding mode of a Na+ ion. We expand our understanding of previous experimental observations and shed light on the mechanisms of the LYS9 deletion associated bleeding disorder by providing consistent but more quantitative and detailed structural analyses than early studies in literature. With a novel application of supervised learning, i.e. the decision tree learning on the hydrogen bonding features in the wild-type and DeltaK9 mutant forms of thrombin, we predict that seven pairs of critical hydrogen bonding interactions are significant for establishing distinct behaviors of wild-type thrombin and its DeltaK9 mutant form. Our calculations indicate the LYS9 in the light chain has both localized and long-range allosteric effects on thrombin, supporting the opinion that light chain has an important role as an allosteric effector. PMID- 29471737 TI - Erratum. PMID- 29471736 TI - Incursions from the epicentre: Southern theory, social science, and the global HIV research domain. AB - Research about HIV constitutes a global domain of academic knowledge. The patterns that structure this domain reflect inequalities in the production and dissemination of knowledge, as well as broader inequalities in geopolitics. Conventional metrics for assessing the value and impact of academic research reveal that "Northern" research remains dominant, while "Southern" research remains peripheral. Southern theory provides a framework for greater critical engagement with knowledge produced by researchers within the global South. With a focus on HIV social science, we show that investigators working in and from Africa have produced and disseminated knowledge fundamental to the global domain of HIV research, and argue that their epistemological contribution may be understood within the framework of Southern theory. Through repurposing a bibliometrical measure of citation count, we constitute a new archive of highly cited social science research. With a focus on South Africa, we situate this archive within changing historical contexts, connecting research findings to developments in medicine, health sciences and politics. We focus on two key themes in the evolution of HIV knowledge: (1) the significance of context and locality - the "setting" of HIV research; and (2) sex, race and risk - changing ideas about the social determinants of HIV transmission. PMID- 29471735 TI - Cognitive impairment in older patients undergoing colorectal surgery. AB - Background With increasing numbers of older people being referred for elective colorectal surgery, cognitive impairment is likely to be present and affect many aspects of the surgical pathway. This study is aimed to determine the prevalence of cognitive impairment and assess it against surgical outcomes. Methods The Montreal Cognitive Assessment (MoCA) was carried out in patients aged more than 65 years. We recorded demographic information. Data were collected on length of hospital stay, complications and 30-day mortality. Results There were 101 patients assessed, median age was 74 years (interquartile range = 68-80), 54 (53.5%) were women. In total, 58 people (57.4%) 'failed' the Montreal Cognitive Assessment test (score <= 25). There were two deaths (3.4%) within 30 days of surgery in the abnormal Montreal Cognitive Assessment group and none in the normal group. Twenty-nine (28.7%) people experienced a complication. The percentage of patients with complications was higher in the group with normal Montreal Cognitive Assessment (41.9%) than abnormal Montreal Cognitive Assessment (19.9%) ( p = 0.01) and the severity of those complications were greater (chi squared for trend p = 0.01). The length of stay was longer in people with an abnormal Montreal Cognitive Assessment (mean 8.1 days vs. 5.8 days, p = 0.03). Conclusion Cognitive impairment was common, which has implications for informed consent. Cognitive impairment was associated with less postoperative complications but a longer length of hospital stay.

PMID- 29471739 TI - Comparison and strategy of nitrogen removal at different low temperatures in a pilot-scale A2/O system. AB - To ensure low effluent total nitrogen (TN <= 15 mg L-1) and NH3-N( <= 5 mg L-1) at low temperatures (8.8-14.7 degrees C), a pilot-scale A2/O system with a low return activated sludge (200%) was employed to seek the optimal operation strategy. In the 90 days' experiment, the tests were separated into three stages (14.2 degrees C, 11.0 degrees C, and 9.1 degrees C), and the 49 samples were analysed. Our results showed that the nitrification was remarkably inhibited when the temperature was below 10 degrees C, while the denitrification was remarkably inhibited at the temperatures of 10-15 degrees C. Once the effluent NH3-N concentration was over 2.5 mg L-1, or [Formula: see text] concentration was over 13 mg L-1, the effluent TN would be in excess of 15 mg L-1. When the temperature was over 10 degrees C, increasing dissolved oxygen (DO) was an optimal strategy to reduce the effluent NH3-N; nevertheless, when the temperature was below 10 degrees C, simultaneously increasing DO and MLVSS would be carried out due to the low max. nitrification rates (36.0 mg (g-1 d-1)). If the carbon source (CODcr/[Formula: see text] ratio >= 7.3) was enough, increasing MLVSS was an effective method to relieve the negative influence of low temperature on denitrification. PMID- 29471740 TI - Orthophosphate modulates the phytotoxicity of nano-ZnO to Lemna minor (L.). AB - Because of their applications in large numbers of products, Zinc Oxide nanoparticles (nano-ZnO) will inevitably enter into the environment. Nano-ZnO released into the environment will be present in a complex matrix which can cause various chemical and physical transformations and modulate the biological reactivity of these particles. Due to their rapid growth and small size, Lemna minor is recommended by OECD for toxicological testing. Here, we tested how nano ZnO reactivity is modulated by the suite of macro- and micronutrients that are present in Lemna minor growth media. Specifically, we measured ex situ Reactive Oxygen Species (ROS) formation by nano-ZnO, and subsequent in planta toxicity. The data show how orthophosphate can modulate both ex situ ROS formation, and in planta toxicity. This has ramifications for phytotoxicity testing, which is commonly performed under controlled conditions and on media containing orthophosphate. PMID- 29471741 TI - Rabies in India: where do we stand? PMID- 29471742 TI - Does Missed Care in Isolated Rural Hospitals Matter? AB - Missed care is associated with adverse outcomes such as patient falls and decreased nurse job satisfaction. Although studied in populations of interest such as neonates, children, and heart failure patients, there are no studies about missed care in rural hospitals. Reducing care omissions in rural hospitals might help improve rural patient outcomes and ensure that rural hospitals can remain open in an era of hospital reimbursement dependent on care outcomes, such as through value-based purchasing. Understanding the extent of missed nursing care and its implications for rural populations might provide crucial information to alert rural hospital administrators and nurses about the incidence and influence of missed care on health outcomes. Focusing on missed care within rural hospitals and other rural health care settings is important to address the specific health needs of aging rural U.S. residents who are isolated from high volume, urban health care facilities. PMID- 29471743 TI - Masticatory performance parameters for young adults with "normal" occlusion. AB - Objective To develop reference data for young men/women on the variability of parameters used for the evaluation of masticatory function with an artificial test food. Methods Subjects included were 200 18-25-year olds with complete dentition and "normal" occlusion. An artificial test food was chewed in two tests (20 cycles and swallowing threshold), during which sequences/cycles were counted and timed. Medium-particle-size (MPS) and broadness of particle distribution were calculated evaluating the chewed material. Reference data was based on order statistics. Sex-specific 95% reference limits with 90% confidence intervals were calculated with RefVal-v2.1-software. Coefficients of variation were also obtained. Results Tables with reference data for young men/women chewing an artificial test food were constructed with the data collected displaying ample variability: MPS after 20 cycles anywhere between 0.7-3.5 mm or 14-84 cycles to deem the test food ready to be swallowed (C.V. 43% males/34% females). Conclusion There is much variability in masticatory parameters for young adults with good oral health. PMID- 29471744 TI - Injury-related gaining momentum as external causes of deaths in Ethiopian health and demographic surveillance sites: evidence from verbal autopsy study. AB - BACKGROUND: In Ethiopia, though all kinds of mortality due to external causes are an important component of overall mortality often not counted or documented on an individual basis. OBJECTIVE: The aim of this study was to describe the patterns of mortality from external causes using verbal autopsy (VA) method at the Ethiopian HDSS Network sites. METHODS: All deaths at Ethiopian HDSS sites were routinely registered and followed up with VA interviews. The VA forms comprised deaths up to 28 days, between four weeks and 14 years and 15 years and above. The cause of a death was ascertained based on an interview with next of families or other caregivers using a standardized questionnaire that draws information on signs, symptoms, medical history and circumstances preceding death after 45 days mourning period. Two physician assigned probable causes of death as underlying, immediate and contributing factors independently using information in VA forms based on the WHO ICD-10 and VA code system. Disagreed cases sent to third physician for independent review and diagnosis. The final cause of death considered when two of the three physicians assigned underlying cause of death; otherwise, labeled as undetermined. RESULTS: In the period from 2009 to 2013, a total of 9719 deaths were registered. Of the total deaths, 623 (6.4%) were from external causes. Of these, accidental drowning and submersion, 136 (21.8%), accidental fall, 113 (18.1%) and transport-related accidents, 112 (18.0%) were the topmost three leading external causes of deaths. About 436 (70.0%) of deaths were from the age group above 15 years old. Drowning and submersion and transport related accidents were high in age group between 5 and 14 years old. CONCLUSION: In this study, external causes of death are significant public health problems and require attention as one of prior health agenda. PMID- 29471746 TI - The trainee leadership blueprint: opportunities, benefits, and a call to action. AB - OBJECTIVE: Leadership experiences are vital not only to individual long-term career success but also the development, direction, and operation of higher spheres including professional organizations and the field of clinical neuropsychology itself. METHOD: The present paper presents a blueprint guide for neuropsychology trainees on available opportunities and resources for increasing their involvement in professional governance and developing leadership skills. First, we present a discussion of the benefits of leadership and professional service, including the acquisition of interpersonal skills and new professional competencies, the prospect of recognition and advancement, and the opportunity to participate in advocacy efforts. Then, we present an overview of existing opportunities for involvement, followed by the provision of specific, actionable items for trainees, mentors and leadership committees, and for neuropsychology organizations to ensure continued trainee engagement. CONCLUSIONS: These resources can serve as a guide for trainees and early career neuropsychologists seeking to acquire leadership proficiencies, and the recommendations aspire to promote advancement for trainees, professionals, and organizations alike. PMID- 29471745 TI - Effects of high ambient temperature on ambulance dispatches in different age groups in Fukuoka, Japan. AB - BACKGROUND: The elderly population has been the primary target of intervention to prevent heat-related illnesses. According to the literature, the highest risks have been observed among the elderly in the temperature-mortality relationship. However, findings regarding the temperature-morbidity relationship are inconsistent. OBJECTIVES: This study aimed to examine the association of temperature with ambulance dispatches due to acute illnesses, stratified by age group. Specifically, we explored the optimum temperature, at which the relative health risks were found to be the lowest, and quantified the health risk associated with higher temperatures among different age groups. METHODS: We used the data for ambulance dispatches in Fukuoka, Japan, during May and September from 2005 to 2012. The data were grouped according to age in 20-year increments. We explored the pattern of the association of ambulance dispatches with temperature using a smoothing spline curve to identify the optimum temperature for each age group. Then, we applied a distributed lag nonlinear model to estimate the risks of the 85th-95th percentile temperature relative to the overall optimum temperature, for each age group. RESULTS: The relative risk of ambulance dispatches at the 85th and 95th percentile temperature for all ages was 1.08 [95% confidence interval (CI): 1.05, 1.12] and 1.12 (95% CI: 1.08, 1.16), respectively. In comparison, among age groups, the optimum temperature was observed as 25.0 degrees C, 23.2 degrees C, and 25.3 degrees C for those aged 0 19, 60-79, and >=80, respectively. The optimum temperature could not be determined for those aged 20-39 and 40-59. The relative risks of high temperature tended to be higher for those aged 20-39 and 40-59 than those for other age groups. CONCLUSIONS: We did not find any definite difference in the effect of high temperature on ambulance dispatches for different age groups. However, more measures should be taken for younger and middle-aged people to avoid heat-related illnesses. PMID- 29471747 TI - Voices of leadership: wisdom from women leaders in neuropsychology. AB - OBJECTIVE: Inspired by panel discussions at various neuropsychology conferences, the aim of this paper is to share wisdom that women in neuropsychology acquired from their leadership experiences. METHOD: We identified 46 women leaders in governance and academic research through reviews of organizational websites and journal editorial boards, and requested their response to brief questions via email. Twenty-one leaders provided responses to three questions formulated by the authors. RESULTS: This paper summarizes the primary themes for the following questions: (1) What advice would you give to a woman neuropsychologist who is seeking to move into a leadership role? Responses included: increase visibility, make connections, know yourself, be confident, and gather information. (2) What leadership style(s) works best? No respondents endorsed a 'best' leadership style; however, they suggested that leaders should know their own personal style, be open and transparent, find a shared mission, and most importantly - use a collaborative approach. (3) What helps a woman earn respect as a leader in neuropsychology? Respondents recommended that leaders should: get involved in the work, demonstrate integrity, do your homework, be dependable, and keep meetings focused. CONCLUSIONS: It is the authors' intent that by gathering and distilling advice from successful women leaders in neuropsychology, more women may be catalyzed to pursue leadership roles in our profession. PMID- 29471748 TI - Editorial: raising awareness about gender bias and disparity in clinical neuropsychology and a call to action. PMID- 29471749 TI - Comparing mentorship and sponsorship in clinical neuropsychology. AB - OBJECTIVE: Mentoring is a well-known concept that is widely regarded as beneficial for personal and professional development. The concept of sponsoring is less recognized although it is considered critical by some for career advancement. The purpose of this study was to provide an initial exploration of differences between mentoring and sponsoring within neuropsychology and to learn what sponsors look for in proteges. METHOD: Twenty neuropsychologists with experience in mentorship and sponsorship were interviewed. Topics covered included the number of proteges they had mentored/sponsored, training received in mentoring/sponsoring, characteristics they look for in proteges, expectations of proteges, reasons they mentor/sponsor, and benefits of mentoring/sponsoring. RESULTS: On average, neuropsychologists interviewed had mentored 58 proteges and sponsored 40. None had ever received formal training in mentoring or sponsoring. Key characteristics needed for neuropsychologists to feel comfortable mentoring/sponsoring proteges were similar while those characteristics valued differed slightly with sponsored proteges valued for competence and getting things done and mentored proteges valued for interpersonal qualities. Reasons for and benefits of mentorship/sponsorship were similar, with rewarding feelings, satisfaction, and pride in the protege's successes at the top of the list. CONCLUSIONS: Neuropsychologists who provide training are in the position to mentor and sponsor individuals; mentoring relationships often entail sponsorship and vice versa such that the two constructs may be considered part of a continuum. Improving knowledge and skills in mentorship and sponsorship will not only advance personal and professional development of proteges but will also positively impact mentors/sponsors and help shape the field of neuropsychology in deliberate ways.

AB - Meat quality traits (MQTs) are very important in the porcine industry, which are mainly determined by skeletal muscle fiber composition, extra-muscular and/or intramuscular fat content. To identify the differentially expressed candidate genes affecting the meat quality traits, first we compared the MQTs and skeletal muscle fiber characteristics in the longissimus dorsi muscle (LDM) of the Northeast Min pig (NM) and the Changbaishan wild boar (CW) with their body weight approaching 90 kg. The significant divergences in the skeletal muscle fiber phenotypes and fatness traits between the two porcine breeds established an ideal model system for further identifying potential key functional genes that dominated MQTs. Further, a transcriptome profile analysis was performed using the Illumina sequencing method in early postnatal developing LDM from the two breeds at the ages of 42 days. Comparative analysis between these two cDNA libraries showed that there were 17,653 and 22,049 unambiguous tag-mapped sense transcripts detected from NM and CW, respectively. 4522 differentially expressed genes (DEGs) were revealed between the two tissue samples, of them, 4176 genes were found as having been upregulated and 346 genes were identified as having been downregulated in the NM library. By pathway enrichment analysis, a set of significantly enriched pathways were identified for the DEGs, which are potentially involved in myofiber development, differentiation and growth, lipogenesis and lipolysis in porcine skeletal muscle. The expression levels of 30 out of the DEGs were validated by real-time quantitative reverse transcriptase PCR (qRT-PCR) and the observed result was consistent noticeably with the Illumina transcriptome profiles. The findings from this study can contribute to future investigations of skeletal muscle growth and development mechanism and to establishing molecular approaches to improve meat quality traits in pig breeding. PMID- 29471751 TI - Maternal serum thrombospondin-1 is significantly altered in cases with established preeclampsia. AB - PURPOSE: The aim of the study was to investigate whether maternal serum TSP-1 level was associated with PE. MATERIALS AND METHODS: In our case control study, 84 pregnant women in the third trimester were included. Forty-one of them were healthy and 43 of them were with the diagnosis of PE. The diagnosis was based on the definitions of the National High Blood Pressure Education Program working Group on High Blood Pressure in Pregnancy. Preeclamptic patients were divided into two subgroups as mild and severe. Blood pressure (BP) of pregnant women were obtained in left-side lying position using a mercury sphygmomanometer after at least 10 minutes of rest. Ten milliliters of venous blood was taken from every pregnant women and dispensed into lithium heparin and serum was obtained. Samples were stored at -80 degrees C until analyzed. Serum TSP-1 level was measured using enzyme-linked immunosorbent assay (ELISA). All tests were two-tailed and p < .05 was considered to be statistically significant. RESULTS: TSP-1 level was significantly lower in PE group than in controls (p = .003). Platelet counts were similar in two groups (p = .26). TSP-1 levels were significantly lower in severe PE than in mild PE cases. According to the subgroup analysis, TSP-1 level was found significantly lower in severe preeclampsia group compared to control group (p = .015). CONCLUSIONS: In light of the association between endothelial dysfunction and preeclampsia, we claim that lower levels of TSP-1 which is released mostly from endothelial cells seem to reflect disease severity in PE. Our study reveals that maternal serum TSP-1 levels decrease in pregnant women presenting with PE and TSP-1 may be a new biomarker for the detection of PE and even severity of it. Further studies especially prospective ones with greater numbers of cases are needed. PMID- 29471752 TI - Simultaneous removal of nitrate and hydrogen sulfide by autotrophic denitrification in nitrate-contaminated water treatment. AB - Nitrate contamination is a risk to human health and may cause eutrophication, whereas H2S is an undesirable constituent in biogas. In order to better understand denitrification using gaseous H2S as electron donor, this study investigated denitrification at different molar ratios of sulfur and nitrogen (S/N ratios) and H2S dosages. Although nitrate continued to decrease, a lag in sulfate generation was observed, implying the generation of sulfide oxidizing intermediates, which accumulated even though nitrate was in excess at lower S/N ratios of 0.19 and 0.38. More addition of H2S could result in a longer lag of sulfate generation. Before depletion of dissolved sulfide, denitrification could proceed with little nitrite accumulation. High throughout sequencing analysis identified two major genera, Thiobacillus and Sulfurimonas, that were responsible for autotrophic denitrification. The simultaneous removal of nitrate and H2S using a wide range of concentrations could be achieved. PMID- 29471753 TI - Evaluation of virus reduction at a large-scale wastewater reclamation plant by detection of indigenous F-specific RNA bacteriophage genotypes. AB - Evaluating the reduction of virus load in water reclamation plants is important to ensuring the hygienic safety of the reclaimed water. A virus-spiking test is usually used to estimate virus reduction but is not practicable at large-scale plants. Thus, we evaluated virus reduction by ultrafiltration (UF) plus ultraviolet (UV) irradiation at a large-scale reclamation plant (1000 m3/d) by quantifying indigenous F-specific RNA bacteriophages (FRNAPHs). To detect the infectious FRNAPH, we used both plaque assay and integrated culture-reverse transcription polymerase chain reaction combined with the most probable number assay, which can detect infectious FRNAPH genotypes. For comparison, we determined reductions of indigenous FRNAPHs and spiked MS2 at a small-scale pilot plant (10 m3/d) at the same time. Reductions by UF were not significantly different among the bacteriophages at pilot plants. This result suggests that indigenous bacteriophages could be used for evaluating virus reduction by UF at large-scale plants. Indigenous Genotype I (GI) FRNAPH showed the highest UV resistance, followed by GII, GIII, and GIV. The resistance of GI-FRNAPH was equivalent to that of spiked MS2. The reduction of the total infectious FRNAPHs determined by plaque assay was affected by the predominant FRNAPH genotype, presumably because of their different UV resistances. Our results reveal that indigenous GI-FRNAPH can be a good alternative indicator to spiked MS2 in view of virus reduction during water reclamation. The reclaimed water from our large scale reclamation plant could be used for irrigation because the expected reduction (6.3 log10) of indigenous GI-FRNAPH achieved the Title 22 (>5 log10). PMID- 29471754 TI - Anoctamin Channels in Human Myometrium: A Novel Target for Tocolysis. AB - BACKGROUND: Spontaneous preterm labor leading to preterm birth is a significant obstetric problem leading to neonatal morbidity and mortality. Current tocolytics are not completely effective and novel targets may afford a therapeutic benefit. OBJECTIVE: To determine whether the anoctamin (ANO) family, including the calcium activated chloride channel ANO1, is present in pregnant human uterine smooth muscle (USM) and whether pharmacological and genetic modulation of ANO1 modulates USM contraction. METHODS: Reverse transcription-polymerase chain reaction (RT PCR), quantitative RT-PCR, and immunohistochemical staining were done to determine which members of the ANO family are expressed in human USM. Uterine smooth muscle strips were studied in an organ bath to determine whether ANO1 antagonists inhibit oxytocin-induced USM contractions. Anoctamin 1 small interfering RNA (siRNA) knockdown was performed to determine its effect on filamentous-/globular (F/G)-actin ratio, a measurement of actin polymerization's role in promoting smooth muscle contraction. RESULTS: Messenger RNA (mRNA) encoding all members of the ANO family (except ANO7) are expressed in pregnant USM tissue. Anoctamin 1 mRNA expression was decreased 15.2-fold in pregnant USM compared to nonpregnant. Anoctamin 1 protein is expressed in pregnant human USM tissue. Functional organ bath studies with pregnant human USM tissue demonstrated that the ANO1 antagonist benzbromarone attenuates the force and frequency of oxytocin-induced contractions. In human USM cells, siRNA knockdown of ANO1 decreases F-/G-actin ratios. CONCLUSION: Multiple members of the ANO family, including the calcium-activated chloride channel ANO1, are expressed in human USM. Antagonism of ANO1 by pharmacological inhibition and genetic knockdown leads to an attenuation of contraction in pregnant human USM. Anoctamin 1 is a potentially novel target for tocolysis. PMID- 29471755 TI - Sustained return to work and work participation after a new legislation obligating employers to notify prolonged sickness absence. AB - AIMS: Return to work (RTW) after prolonged sickness absence benefits both the individual and society. However, the effectiveness of legislation aiming to improve RTW remains uncertain. We examined whether sustained RTW and work participation were different before and after a legislative change enacted in 2012 (i.e. an intervention) that obligated employers to give notice of prolonged sickness absence to occupational health services. METHODS: Two random samples (2010 and 2013) of the Finnish working aged population (70%, ~2.6 million each) were drawn. Using survival analysis, we assessed sustained RTW (>=28 consecutive working days) during a two-month follow-up after a sickness absence minimum of 30 calendar days in the pre- and post-intervention period. We also identified pathways for RTW with cluster analysis and calculated relative gain in work participation in the total sample and by several population subgroups. RESULTS: In the total sample, sustained RTW was 4% higher and the mean time to sustained RTW was 0.42 days shorter in the post- than in the pre-intervention period. The estimates were larger among women than men and among those with mental disorders compared with other diagnoses. Changes in the pathways for sustained RTW indicated a 4.9% relative gain in work participation in the total sample. The gain was larger among those who lived in areas of low unemployment rate (20.6%) or worked in the public sector (11.9%). CONCLUSIONS: From 2010 to 2013, RTW and work participation increased among the employees with prolonged sickness absence, suggesting that the legislative change enhanced RTW. The change in work participation varied by population subgroup. PMID- 29471756 TI - Age and gender differences in the impact of labour-market transitions on subjective health in Germany. AB - AIMS: Applying a gender- and age group-sensitive approach, we investigated the effect of labour-market transitions (job loss and re-employment) on subjective physical and mental health. METHODS: A combination of the difference-in differences approach and propensity score matching controls for selectivity and initial health differences. This allowed us to analyse the causal effect of job loss and re-employment on subjective health. We made use of data from the German Panel Study Labour Market and Social Security and combined survey information with administrative records of the Federal Employment Agency for employed and unemployed men and women 31-60 years of age ( n = 2213). We controlled for labour market experiences before the time period under study and for labour-market transitions between the interviews. Subjective health was assessed using the SF 12 health questionnaire, enabling us to differentiate between subjective mental and physical health functioning. RESULTS: We found that physical health was affected mainly in older persons between 45 and 60 years old. Controlling for covariates using propensity score matching, mental health was affected only when living-wage jobs (i.e. jobs that provide sufficient income to achieve a defined minimum standard of living above the social benefit level) are gained or lost. Younger women showed a significant improvement in mental health after re employment. In contrast, job loss affected only older individuals' mental health, with a particularly negative effect observed for men. CONCLUSIONS: Our results not only showed that women and men are affected differently by job loss and re employment, but also that age is an important factor. Older men were affected most severely by job loss, whereas re-employment was found to improve mental health only in women aged 31-44 years. It is therefore important to address the health problems of different socio-demographic groups separately, and to apply active labour-market policies with regard to unemployed men and women with health impairments. Based on our results, we suggest the promotion of employment with income levels above the maximum welfare benefit award. PMID- 29471757 TI - Unfit for work: Health and labour-market prospects. AB - AIM: The aim of this study was to examine whether health status (number of chronic diseases, health shock and use of tranquilizers/sleeping pills) is related to labour-market outcomes later in life. METHODS: Twin data for Finnish men and women who were at least 33 years old in 1990 were linked to comprehensive register-based information on unemployment and the incidence of disability pension. We used the within-twin dimension of the data to account for shared family and genetic factors. Self-reported information on the number of diagnosed chronic diseases, health shock and drug use were obtained from the 1975 and 1981 twin surveys, when the twins were at least 18 years old. Unemployment months and the incidence of disability pension were measured during prime working age over the 1990-2004/2009 period. RESULTS: Poor health status is significantly positively related to unemployment and the incidence of disability pension. The results are robust to controlling for shared family and genetic factors and the key measures of risky health behaviours (alcohol use, lifetime smoking and body mass index). CONCLUSIONS: Health status is a fundamental determinant of long-term labour-market outcomes. PMID- 29471758 TI - Impact of a personalised active labour market programme for persons with disabilities. AB - AIMS: The paper estimates the impact of a supported employment programme implemented in Hungary. METHODS: This is a non-experimental evaluation using a matching identification strategy supported by rich data on individual characteristics, personal employment and unemployment history and the local labour market situation. We use a time-window approach to ensure that programme participants and matched controls entered unemployment at the same point in time, and thus faced very similar labour market conditions. RESULTS: We find that the programme had a positive effect of 16 percentage points on the probability of finding a job among men and 25 percentage points among women. The alternative outcome indicator of not re-entering the unemployment registry shows somewhat smaller effects in the case of women. CONCLUSIONS: In comparison to similarly costly programmes that do not facilitate employment in the primary labour market, rehabilitation services represent a viable alternative. PMID- 29471759 TI - Pieces in a big puzzle: On the relationship between health and employment. PMID- 29471760 TI - Working while on a disability pension in Finland: Association of diagnosis and financial factors to employment. AB - AIMS: The aim of this study was to find out whether health and financial factors are associated with engagement in paid work during a disability pension. METHODS: The data included a 10 per cent sample of Finns aged 20-62 years who were drawing earnings-related full or partial disability pension in 2012 ( n = 14,418). Logistic regression analysis was used to estimate odds ratios for working while on a full or partial disability pension. RESULTS: Fourteen per cent of full disability pensioners and 76 per cent of partial disability pensioners were engaged in paid work. Full disability pensioners due to mental disorders were working less often than full disability pensioners due to other diseases. Partial disability pensioners due to cardiovascular diseases were working more than partial disability pensioners due to other diseases. More recent timing of disability pension was associated with working for both partial and full disability pensioners. Working while on disability pension was more common among those with higher education. Partial disability pensioners with average pension worked more often than those with high pension. CONCLUSIONS: By knowing the factors associated with working while on a disability pension, policies could be more efficiently allocated to encourage disability pensioners to take up work. One way would be to support disability pensioners with low education to work more. Another way to increase work among disability pensioners is to support the recently retired in working longer. PMID- 29471761 TI - Health and retirement age: Comparison of expectations and actual retirement. AB - AIM: We examine the relationship between the subjective assessment of health status and retirement by using information on expected and actual retirement ages. METHODS: Subjective data from cross-sectional surveys, conducted in Finland in 2003 and 2008, are linked to information on actual retirement age from register data from 2003 to 2013. Regression models are estimated for actual and expected retirement ages. RESULTS: While the health status is positively correlated with both actual and anticipated full-time retirement age, the actual age of retirement is less sensitive to health. On average, individuals tend to retire later than they had anticipated. We examine potential biases in the health retirement relationship. Measurement error in regard to health status biases the results downwards. Using data on observed retirement ages, omitting those who do not retire during the data period, leads to a selection problem. Ignoring the selection also leads to a downwards bias in the health-retirement age connection. As a more exogenous health variable we use health shocks, which are measured by average annual days of absence due to sickness in the follow-up period. These shocks are negatively related to retirement age in a subsample of initially healthy individuals. CONCLUSIONS: When subjective assessment of health is used for explaining retirement behavior, the effects of health can often be underestimated rather than overestimated. To lengthen working careers, attention should be given to both the ability (health) and willingness (perceptions of proper retirement age) of people to continue longer at work. PMID- 29471762 TI - Impact of cocaine use on protease inhibitor-associated dyslipidemia in HIV infected adults. AB - Previous studies have demonstrated a link between protease inhibitor (PI)-based therapy and lipid dysregulation. The main objective of this study was to examine whether cocaine use may modify PI-associated dyslipidemia in adults. Between June 2003 and June 2014, 957 human immunodeficiency virus (HIV)-infected participants in Baltimore, Maryland were enrolled in a study that investigated HIV/antiretroviral therapy-associated comorbidities. Multiple linear and logistic regression models were fitted to examine the associations between PI therapy and lipid profiles for the pooled sample and cocaine use subgroups, respectively. Total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), TC/high density lipoprotein cholesterol (HDL-C) ratio, and atherogenic index of plasma (AIP) levels were positively associated with duration of PI-based therapy in long term cocaine users (all p < 0.05). However, longer-term PI therapy was significantly associated with increased HDL-C in non-chronic cocaine users (beta = 0.109, SE = 0.042, p < 0.05). The participants who received PI therapy >=12 months and used cocaine >=15 years were more likely to have hypertriglyceridemia (OR = 2.82, 95% CI = 1.63, 4.88) and abnormal AIP (OR = 1.73, 95% CI = 1.08, 2.79) as compared to their counterparts. Our findings showed that long-term cocaine use may exacerbate adverse effects of PI therapy on lipid metabolism, suggesting that reduced cocaine use may be considered an alternative approach to managing PI-associated dyslipidemia in chronic cocaine users with HIV infection. PMID- 29471763 TI - Risk factors associated with sexually transmitted infections among women under community supervision in New York City. AB - The number of women under community supervision in the United States has increased, and this population has a high risk for sexually transmitted infections (STIs). We examined STI prevalence and multiple risk factors among drug-involved women under community supervision in New York City. Data were from a randomized controlled trial testing the efficacy of a behavioral HIV/STI intervention (Women on the Road to Health [WORTH]) among drug-involved women in the community corrections system in New York City from 2009 to 2012. To be eligible for inclusion, women had to be under community supervision within the past 90 days, have used illicit drugs at least once in the past six months, and have unprotected sex at least once in the past 90 days. Participants completed a survey containing items on STI risk factors and were tested for Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis. Multivariable regression was used to examine associations between risk factors and STI diagnosis. Of 333 women tested, 89 (26.7%) tested positive for an STI. Ten (3.0%) were positive for C. trachomatis, 4 (1.2%) for N. gonorrhoeae, and 77 (23.1%) for T. vaginalis. Women with any STI were more likely to be black (AOR: 2.02; 95% CI: 1.08-3.77), homeless in the past 90 days (AOR: 2.07; 95% CI: 1.01-4.26), arrested in the past 90 days (AOR: 1.97; 95% CI: 1.14-3.39), and have a greater number of sexual partners in the past 90 days (AOR: 1.24; 95% CI: 1.08-1.42). Drug-using women under community supervision have a high burden of STIs driven by multiple risk factors. Implementing STI screening, prevention, and treatment programs in community supervision settings could facilitate a reduction in STIs among this population. PMID- 29471764 TI - Oropharyngeal HPV infection: prevalence and sampling methods among HIV-infected men in South Africa. AB - Worldwide, 96,000 cases of oropharyngeal cancer (OPC) occurred in 2012. Human papillomavirus (HPV) is a risk factor for OPC. Data on oropharyngeal HPV infection are limited. There is no consensus on the best sampling method for detecting the infection. We describe the prevalence of oropharyngeal HPV infection among HIV-infected men and compare the performance of oral rinses and swabs in detecting oropharyngeal HPV infection. Paired oral rinses and swabs for 181 men were tested for HPV DNA using the Roche Linear Array. Performance was determined by the number of infections detected and the percentage of samples with adequate DNA extraction. Agreement between sampling methods was assessed by the kappa statistic. Prevalence of oropharyngeal HPV infection with rinse samples was 1.8% (three infections) and 0.6% (one infection) with swabs (p = 0.06). Adequate cellular DNA extraction was more likely with rinse (93.4%) than swab samples (89.0%, p = 0.05). There was moderate agreement between the methods (kappa = 0.49). The prevalence of oropharyngeal HPV DNA infection among this predominantly heterosexual sample of men living with HIV was low and consistent with the infrequent oral sex practices. Oral rinse performed better than oral swab in detecting oropharyngeal HPV DNA infection and might contribute to screening for OPCs. PMID- 29471765 TI - Non-consensual sterilization of women living with HIV. AB - Women living with HIV are stigmatized and discriminated against. They often wish to have children, but they are subjected to the practice of forced (involuntary) sterilization in at least 27 countries under the guise of protecting maternal health and preventing the birth of infected infants. Some women are not asked to give consent, or a third party consents on their behalf. Others are given insufficient information or fed misinformation. The circumstances under which such women have been asked to sign consent forms for sterilization include fear, coercion, intimidation, and undue influence. Courts have been clear that such practice is a breach of human rights, but, so far, it has not been formally declared in courts that such practice constitutes discrimination. More needs to be done in terms of education, sanctions against those who carry out this practice, and help for victims. PMID- 29471768 TI - Their Time Has Come: Providing Culturally Competent Care to LGBT Older Adults. PMID- 29471769 TI - Providing Competent and Affirming Services for Transgender and Gender Nonconforming Older Adults. AB - Despite the growing visibility and acceptance of transgender and gender nonconforming (TGNC) individuals, TGNC older adults experience many barriers in accessing competent and affirming health and social services due to anti-TGNC prejudice, discrimination, and lack of competent healthcare training on the part of healthcare workers. Clinical gerontologists and geriatricians will likely encounter TGNC adults in their practice given population aging and greater numbers of TGNC people who are living in their affirmed gender identities. The American Psychological Association recently published its Guidelines for Psychological Practice with Transgender and Gender Nonconforming People, which document the unique needs of TGNC individuals and outlines approaches for competent and affirming service provision (APA, 2015). We interpret these Guidelines using a gerontological lens to elucidate specific issues faced by the TGNC older adult along with the practice and policy implications for this population. PMID- 29471770 TI - Exploring Staff Clinical Knowledge and Practice with LGBT Residents in Long-Term Care: A Grounded Theory of Cultural Competency and Training Needs. AB - OBJECTIVES: Existing literature shows that LGBT residents are likely to face suboptimal care in LTC facilities due to prejudice and discriminatory policies. The aim of this project was to assess the LGBT cultural competency of staff working in LTC facilities, identify their current training needs, and develop a framework for understanding LGBT cultural competency among LTC staff and providers. METHODS: This grounded theory study comprised data from focus groups of interdisciplinary staff from three LTC facilities. RESULTS: Results suggested that LTC staff struggle with how to be sensitive to LGBT residents' needs. Tension appeared to exist between wanting to provide an equal standard of care to all LTC residents and fearing they would show "favoritism" or "special treatment," which might be viewed as unprofessional. Participants indicated training could help to address the ambivalence they experience about providing sensitive care to subpopulations of residents who face stigma and oppression. CONCLUSIONS: LTC staff stand to benefit from cultural competency training focused on LGBT residents. Training should be not only informational in nature, but also facilitate greater self-awareness and self-efficacy with respect to providing care to LGBT people. PMID- 29471771 TI - The Effect of a Self-management Program on the Quality-of-Life of Community dwelling Older Adults with Chronic Musculoskeletal Knee Pain: A Pilot Randomized Controlled Trial. AB - OBJECTIVES: To evaluate a 6-week self-management program on pain conducted in a mobile setting at the residences of older adult participants. METHODS: In this single-blinded randomized controlled trial, 46 community-dwelling older adults with chronic knee pain were randomly assigned to the experimental (n = 19) and wait-list control groups (n = 27). The experimental group engaged in the 6-week program while the control group was only given some pamphlets on exercise and joint care. The pain level, physical functions, QOL, and self-efficacy of the participants in both groups were assessed at baseline, post-program, and at the 1 month follow-up session. Both baseline and post-program (or post-control-period assessment) data were analyzed. RESULTS: The results showed that the participants in the experimental group had a higher level of self-efficacy, better performance in walking test, a higher level of quality-of-life, and less frequency of pain at the post-program follow-up as compared to the control group. The effect was maintained among the experimental group at post-4-week follow-up and further reduction in pain was detected. CONCLUSIONS: The program appeared to be effective at improving the pain status, self-efficacy, functional performance, and quality of-life of older adults. However, as the sample size was small, further study is suggested to investigate the effects of the program. PMID- 29471772 TI - A Randomized Control Study on Psycho-Education Group on Improving Health-Related Quality of Life of Chinese Persons with Major Neurocognitive Disorder. AB - OBJECTIVES: People with a major neurocognitive disorder (PwND) are found to have a lower health related quality of life (HRQoL) than those without neurocognitive disorder. This research study aims to evaluate the effectiveness of a psycho education group in improving the HRQoL of Chinese PwND. METHODS: By adopting randomized control trial (RCT), Chinese PwND were randomly assigned to either a 10-session psycho-education group or the control group. Family caregivers of treatment group were encouraged to take part in two sessions focusing on the caring and communication skills. Control group and their family caregivers received standardized educational materials on basic information on neurocognitive disorder for them to read at home. Standardized assessment was conducted both with PwND and their caregivers independently to give the self rated and caregiver-rated HRQoL of PwND in the pre- and post- treatment periods by a research assistant who was blind to the group assignment of the participants. Moreover, qualitative interviews were also conducted for ten participants and five family caregivers of the treatment group to identify those group elements relating to its effectiveness. RESULTS: 2 * 2 repeated measures ANCOVA demonstrated that the treatment group (n = 32) was significantly more effective than the control group (n = 32) in improving the caregiver-rated HRQoL (F[1, 61] = 4.35, p = .04 < .05) with a moderate effect size, but not self-rated HRQoL, Qualitative analysis suggested several group elements relating to its effectiveness. CONCLUSIONS: This present RCT shows that the psycho-education group significantly improves caregiver-rated HRQoL of PwND, supporting the feasibility and effectiveness of the psycho-education group. PMID- 29471773 TI - Religiousness and Psychological Distress in Jewish and Christian Older Adults. AB - OBJECTIVES: In this study, the authors explore how the association between religiousness and psychological distress varies by religious affiliation. Prior work has shown that the association between religious belief and psychological distress is stronger for Christians than Jews, while religious activity is associated with lower psychological distress for both groups. METHODS: Interviews were conducted using a community sample of 143 Christian and Jewish older adults, ages 65 and over. Quantitative measures were used to assess levels of organizational and intrinsic religiosity, as well as symptoms of depression and anxiety. RESULTS: Christians who are highly involved in the organizational aspects of their religion report fewer depressive symptoms than Jews who have high levels of organizational religiosity, and the opposite is the case at lower levels of organizational religiosity. No significant group differences were found in the relationship between religiousness and anxiety. CONCLUSIONS: The results of this study indicate a difference between Jews and Christians in the reasons that they turn to their respective religious services, particularly in late life. PMID- 29471774 TI - Cognitive Training Program to Improve Working Memory in Older Adults with MCI. AB - OBJECTIVES: Deficits in working memory (WM) are associated with age-related decline. We report findings from a clinical trial that examined the effectiveness of Cogmed, a computerized program that trains WM. We compare this program to a Sham condition in older adults with Mild Cognitive Impairment (MCI). METHODS: Older adults (N = 68) living in the community were assessed. Participants reported memory impairment and met criteria for MCI, either by poor delayed memory or poor performance in other cognitive areas. The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS, Delayed Memory Index) and the Clinical Dementia Rating scale (CDR) were utilized. All presented with normal Mini Mental State Exams (MMSE) and activities of daily living (ADLs). Participants were randomized to Cogmed or a Sham computer program. Twenty-five sessions were completed over five to seven weeks. Pre, post, and follow-up measures included a battery of cognitive measures (three WM tests), a subjective memory scale, and a functional measure. RESULTS: Both intervention groups improved over time. Cogmed significantly outperformed Sham on Span Board and exceeded in subjective memory reports at follow-up as assessed by the Cognitive Failures Questionnaire (CFQ). The Cogmed group demonstrated better performance on the Functional Activities Questionnaire (FAQ), a measure of adjustment and far transfer, at follow-up. Both groups, especially Cogmed, enjoyed the intervention. CONCLUSIONS: Results suggest that WM was enhanced in both groups of older adults with MCI. Cogmed was better on one core WM measure and had higher ratings of satisfaction. The Sham condition declined on adjustment. PMID- 29471775 TI - Coping: Impact of Gender and Stressful Life Events in Middle and in Old Age. AB - OBJECTIVES: This study seeks to identify different life events that participants considered stressful and to study the joint effect of gender, age group, and main stressful life events on the use of different coping strategies. METHODS: The sample comprised 243 men and women, 55 to 99 years old, who attended senior activity centers. Analyses were conducted using multivariate analysis of variance (MANOVA). RESULTS: Three main categories of stressful life events were identified: health problems, family problems, and other problems. Significant main effects of gender and stressful life events, and marginal effects of age group on coping strategies were found. Furthermore, an interaction between gender and age group, and also between gender and stressful life events emerged in some of the coping strategies analyzed. CONCLUSIONS: Age, gender or type of stressful situation impact on the coping strategies used by older people. Older men and women were found to use different strategies depending upon the situation they are facing and upon their age group. The results may prove useful to practitioners and clinicians who directly work with older people and may help clinicians provide effective coping strategies to address the specific life events that older adults find stressful. PMID- 29471777 TI - Spontaneous and Drug-induced Arteritis/Polyarteritis in the Gottingen Minipig Review. AB - Arteritis/polyarteritis occurs spontaneously in many species used in preclinical toxicology studies. In Gottingen minipigs, arteritis/polyarteritis is an occasionally observed background change. In the minipig, this finding differs in frequency and nature from age-related polyarteritis nodosa in rats or monkeys, and Beagle pain syndrome in dogs. In minipigs, it can be present in a single small- or medium-sized artery of an organ or a few organs and is most commonly recorded in the cardiac and extracardiac blood vessels, vagina, oviduct, rectum, epididymis, spinal cord, pancreas, urinary bladder, kidneys, and stomach. The etiology is unknown although it has been considered in minipigs as well as in rats, dogs, and monkeys to be possibly immune mediated. This background change is important with respect to its nature and distribution in the minipig in order to distinguish it from drug-induced vascular changes, which might occur in similar locations and have similar morphologic features. This review summarizes the morphology, incidence, and predilection sites of arteritis as a spontaneously occurring background change and as a drug-induced vasculopathy in the minipig, and also describes the main aspects to consider when evaluating vascular changes in Gottingen minipig toxicity studies and their human relevance. PMID- 29471776 TI - T-cell Immunotherapies and the Role of Nonclinical Assessment: The Balance between Efficacy and Pathology. AB - Gene-engineered T-cell therapies have the potential to revolutionize the treatment of cancer. These therapies have shown exceptional clinical efficacy specifically in the field of B-cell malignancies and the first products (KymriahTM and YescartaTM) have recently been approved in the United States for specific indications. The power of these treatments is also linked with a distinct set of toxicities both predicted and unpredicted, including off-tumor activity, cytokine release syndromes, and neurotoxicity, occasionally with fatal consequences. As these therapies begin to reach more patients, it is critical to develop the nonclinical tools to adequately determine the mechanisms driving these toxicities, to assess the safety risks of candidate products, and to develop strategies for safety management. PMID- 29471778 TI - Evaluation of Uracil, Sodium Ascorbate, and Rosiglitazone as Promoters of Urinary Bladder Transitional Cell Carcinomas in Male Sprague-Dawley Rats. AB - The purpose of this study was to establish a 2-stage model of urinary bladder carcinogenesis in male Sprague-Dawley rats to identify tumor promoters. In phase 1 of the study, rats ( n = 170) were administered 100 mg/kg of the tumor initiator, N-butyl-N-(4-hydroxybutyl)-nitrosamine (BBN), twice weekly by oral gavage (po) for a period of 6 weeks. Phase 2 consisted of dividing rats into 4 groups ( n = 40 per group) and administering one of the following for 26 weeks to identify putative tumor promoters: (1) vehicle po, (2) 25 mg/kg/day rosiglitazone po, (3) 5% dietary sodium l-ascorbate, and (4) 3% dietary uracil. Rats were necropsied after 7.5 months, and urinary bladders were evaluated by histopathology. BBN/vehicle treatments induced the development of urothelial hyperplasia (83%) and papillomas (15%) but no transitional cell carcinomas (TCCs). Rosiglitazone increased the incidence and severity of papillomas (93%) and resulted in TCC in 10% of treated rats. Uracil was the most effective tumor promoter in our study and increased the incidence of papillomas (90%) and TCC (74%). Sodium ascorbate decreased the incidence of urothelial hyperplasia (63%) and did not increase the incidence of urothelial papillomas or TCC. These data confirm the capacity of our 2-stage model to identify urinary bladder tumor promoters. PMID- 29471779 TI - Characterizing Adversity of Lysosomal Accumulation in Nonclinical Toxicity Studies: Results from the 5th ESTP International Expert Workshop. AB - Lysosomes have a central role in cellular catabolism, trafficking, and processing of foreign particles. Accumulation of endogenous and exogenous materials in lysosomes represents a common finding in nonclinical toxicity studies. Histologically, these accumulations often lack distinctive features indicative of lysosomal or cellular dysfunction, making it difficult to consistently interpret and assign adverse dose levels. To help address this issue, the European Society of Toxicologic Pathology organized a workshop where representative types of lysosomal accumulation induced by pharmaceuticals and environmental chemicals were presented and discussed. The expert working group agreed that the diversity of lysosomal accumulations requires a case-by-case weight-of-evidence approach and outlined several factors to consider in the adversity assessment, including location and type of cell affected, lysosomal contents, severity of the accumulation, and related pathological effects as evidence of cellular or organ dysfunction. Lysosomal accumulations associated with cytotoxicity, inflammation, or fibrosis were generally considered to be adverse, while those found in isolation (without morphologic or functional consequences) were not. Workshop examples highlighted the importance of thoroughly characterizing the biological context of lysosomal effects, including mechanistic data and functional in vitro readouts if available. The information provided here should facilitate greater consistency and transparency in the interpretation of lysosomal effects. PMID- 29471780 TI - How large B-factors can be in protein crystal structures. AB - BACKGROUND: Protein crystal structures are potentially over-interpreted since they are routinely refined without any restraint on the upper limit of atomic B factors. Consequently, some of their atoms, undetected in the electron density maps, are allowed to reach extremely large B-factors, even above 100 square Angstroms, and their final positions are purely speculative and not based on any experimental evidence. RESULTS: A strategy to define B-factors upper limits is described here, based on the analysis of protein crystal structures deposited in the Protein Data Bank prior 2008, when the tendency to allow B-factor to arbitrary inflate was limited. This B-factor upper limit (B_max) is determined by extrapolating the relationship between crystal structure average B-factor and percentage of crystal volume occupied by solvent (pcVol) to pcVol =100%, when, ab absurdo, the crystal contains only liquid solvent, the structure of which is, by definition, undetectable in electron density maps. CONCLUSIONS: It is thus possible to highlight structures with average B-factors larger than B_max, which should be considered with caution by the users of the information deposited in the Protein Data Bank, in order to avoid scientifically deleterious over interpretations. PMID- 29471781 TI - Solid lipid curcumin particles provide greater anti-amyloid, anti-inflammatory and neuroprotective effects than curcumin in the 5xFAD mouse model of Alzheimer's disease. AB - BACKGROUND: Neuroinflammation and the presence of amyloid beta protein (Abeta) and neurofibrillary tangles are key pathologies in Alzheimer's disease (AD). As a potent anti-amyloid and anti-inflammatory natural polyphenol, curcumin (Cur) could be potential therapies for AD. Unfortunately, poor solubility, instability in physiological fluids, and low bioavailability limit its clinical utility. Recently, different lipid modifications in the formulae of Cur have been developed that would enhance its therapeutic potential. For example, we have reported greater permeability and neuroprotection with solid lipid curcumin particles (SLCP) than with natural Cur in an in vitro model of AD. In the present study, we compared the Abeta aggregation inhibition, anti-amyloid, anti inflammatory responses of Cur and or SLCP in both in vitro and in vivo models of AD. One-year-old 5xFAD-and age-matched wild-type mice were given intraperitoneal injections of Cur or SLCP (50 mg/kg body weight) for 2- or 5-days. Levels of Abeta aggregation, including oligomers and fibril formation, were assessed by dot blot assay, while Abeta plaque load and neuronal morphology in the pre-frontal cortex (PFC) and hippocampus were assayed by immunolabeling with Abeta-specific antibody and cresyl violet staining, respectively. In addition, neuroinflammation was assessed the immunoreactivity (IR) of activated astrocytes (GFAP) and microglia (Iba-1) in different brain areas. Finally, comparisons of solubility and permeability of Cur and SLCP were made in cultured N2a cells and in primary hippocampal neurons derived from E16 pups of 5xFAD mice. RESULTS: We observed that relative to Cur, SLCP was more permeable, labeled Abeta plaques more effectively, and produced a larger decrease in Abeta plaque loads in PFC and dentate gyrus (DG) of hippocampus. Similarly, relative to Cur, SLCP produced a larger decrease of pyknotic, or tangle-like, neurons in PFC, CA1, and CA3 areas of hippocampus after 5 days of treatment. Both Cur and or SLCP significantly reduced GFAP-IR and Iba-1-IR in PFC, in the striatum as well as CA1, CA3, DG, subicular complex of hippocampus, and the entorhinal cortex in the 5xFAD mice after 5 days of treatment. CONCLUSIONS: The use of SLCP provides more anti amyloid, anti-inflammatory, and neuroprotective outcomes than does Cur in the 5xFAD mouse model of AD. PMID- 29471782 TI - Transcapillary fluid flux and inflammatory response during neonatal therapeutic hypothermia: an open, longitudinal, observational study. AB - BACKGROUND: Therapeutic hypothermia is neuroprotective in asphyxiated neonates by counteracting mechanisms contributing to brain injury. Although an initial increased permeability is part of an inflammatory reaction and thereby a natural healing process, an excessive endothelial permeability with edema formation may result in impaired hemodynamics. Reduced permeability may, however, benefit healing. Although plasma and interstitial colloid osmotic pressure are accessible and essential parameters for understanding fluid imbalance, the mechanisms of fluid exchange remain poorly understood. The potential influence of therapeutic hypothermia on plasma and interstitial colloid osmotic pressure, and the relationship between inflammatory markers and colloid osmotic pressure in asphyxiated neonates, was investigated. METHODS: Seventeen neonates with moderate to severe hypoxic ischemic encephalopathy, born after 35 weeks gestation, received servo-controlled whole body cooling before 6 h of age, followed by gradual rewarming after 72 h. All infants were treated according to a national hypothermia protocol. Interstitial fluid in the skin was collected at 7, 13, 25, 49, and 73 h after birth by subcutaneous implantation of multifilamentous nylon wicks with 60 min of implantation time. Biomarkers of inflammation and colloid osmotic pressure were measured in serum and interstitial fluid. RESULTS: A modest decrease in serum and interstitial colloid osmotic pressure was measured, leaving an unaltered difference in colloid osmotic pressure gradient. A decline in mean arterial pressure was observed between 7 and 13 h of life, with a concomitant decrease in positive fluid balance within the same time frame. White blood cell count and leukocyte subclasses dropped significantly throughout treatment, with elevated interstitial interleukin (IL)-1alpha and decreased serum IL-1RA, IL-6, and IL-10 during treatment time points. CONCLUSIONS: Colloid osmotic pressures measured in serum and interstitial fluid during asphyxia is lower than previously reported, with small alteration of pressure differences across capillaries, reducing vascular filtration. An inherent local and systemic regulation of inflammation together with changes in colloid osmotic pressure may indicate a possible preventive mechanism of edema generation during neonatal asphyxia and therapeutic hypothermia. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT01044940 . Date of registration: January 8, 2010. PMID- 29471783 TI - Seroprevalence of dengue IgG antibodies in symptomatic and asymptomatic individuals three years after an outbreak in Zhejiang Province, China. AB - BACKGROUND: Cross-reacting antibodies enhanced dengue infection in humans and antibody dependent enhancement (ADE) have been proposed as early mechanisms underlying DHF/DSS. However, the duration of dengue IgG antibodies in the body as well as factors associated with said duration remain unclear. METHODS: Blood samples from 59 dengue symptomatic persons and 48 asymptomatic individuals were collected. Study participant demographic information (including age in 2009, gender, and place of residence) were also collected. Serum samples were tested for dengue specific IgG by Panbio dengue IgG indirect enzyme-linked immunosorbent assay (ELISA). Chi-square tests and logistic regression analysis of dengue IgG antibodies seroprevalence divided by gender, age groups, and symptomatic or asymptomatic infection were conducted using the Statistical Package for the Social Sciences. RESULTS: Overall, 70 (65.42%) blood samples were seropositive for dengue IgG antibodies with similar seroprevalences found when dividing by gender and different age groups. However, seroprevalence of dengue IgG antibodies in samples from dengue symptomatic persons was significantly higher than that in samples from asymptomatic individuals (96.61% vs 27.08%) according to multivariable logistic regression analysis, the odds ratio (OR) of the factor was 76.731. CONCLUSIONS: Dengue IgG antibodies were detectable in samples from most individuals three years after infection. Dengue symptomatic persons had a higher dengue IgG prevalence compared to asymptomatic individuals. PMID- 29471784 TI - Potential cost savings to be made by slowing cognitive decline in mild Alzheimer's disease dementia using a model derived from the UK GERAS observational study. AB - BACKGROUND: Given the high costs associated with the care of those with Alzheimer's disease (AD) dementia, we examined the likely impact of a reduction in the rate of cognitive decline upon cost outcomes associated with this disease. METHODS: Using the group of patients with mild AD dementia from the GERAS study, generalised linear modelling (GLM) was used to explore the relationship between change in cognition as measured using the Mini-Mental State Examination (MMSE) and UK overall costs (health care and social care costs, and total societal costs) associated with AD dementia. RESULTS: A total of 200 patients with mild AD dementia were identified. Least squares mean (LSM) +/- standard error (SE) reduction in MMSE score was 3.6 +/- 0.4 points over 18 months. Using GLM it was possible to calculate that this worsening in cognition was associated with an 8.7% increase in total societal costs, equating to an increase of approximately L2200 per patient over an 18-month period. If the rate of decline in cognition was reduced by 30% or 50%, the associated savings in total societal costs over 18 months would be approximately L670 and L1100, respectively, of which only L110 and L180, respectively, could be attributed to a saving of health care costs. CONCLUSION: This study demonstrates that there are potential savings to be made in the care of patients with AD dementia through reducing the rate of cognitive decline. A reduction in wider societal costs is likely to be the main contributor to these potential savings, and need to be further evaluated when intervention costs and cost offsets can be measured. PMID- 29471785 TI - Phylogeny with introgression in Habronattus jumping spiders (Araneae: Salticidae). AB - BACKGROUND: Habronattus is a diverse clade of jumping spiders with complex courtship displays and repeated evolution of Y chromosomes. A well-resolved species phylogeny would provide an important framework to study these traits, but has not yet been achieved, in part because the few genes available in past studies gave conflicting signals. Such discordant gene trees could be the result of incomplete lineage sorting (ILS) in recently diverged parts of the phylogeny, but there are indications that introgression could be a source of conflict. RESULTS: To infer Habronattus phylogeny and investigate the cause of gene tree discordance, we assembled transcriptomes for 34 Habronattus species and 2 outgroups. The concatenated 2.41 Mb of nuclear data (1877 loci) resolved phylogeny by Maximum Likelihood (ML) with high bootstrap support (95-100%) at most nodes, with some uncertainty surrounding the relationships of H. icenoglei, H. cambridgei, H. oregonensis, and Pellenes canadensis. Species tree analyses by ASTRAL and SVDQuartets gave almost completely congruent results. Several nodes in the ML phylogeny from 12.33 kb of mitochondrial data are incongruent with the nuclear phylogeny and indicate possible mitochondrial introgression: the internal relationships of the americanus and the coecatus groups, the relationship between the altanus, decorus, banksi, and americanus group, and between H. clypeatus and the coecatus group. To determine the relative contributions of ILS and introgression, we analyzed gene tree discordance for nuclear loci longer than 1 kb using Bayesian Concordance Analysis (BCA) for the americanus group (679 loci) and the VCCR clade (viridipes/clypeatus/coecatus/roberti groups) (517 loci) and found signals of introgression in both. Finally, we tested specifically for introgression in the concatenated nuclear matrix with Patterson's D statistics and DFOIL. We found nuclear introgression resulting in substantial admixture between americanus group species, between H. roberti and the clypeatus group, and between the clypeatus and coecatus groups. CONCLUSIONS: Our results indicate that the phylogenetic history of Habronattus is predominantly a diverging tree, but that hybridization may have been common between phylogenetically distant species, especially in subgroups with complex courtship displays. PMID- 29471786 TI - Dengue score as a diagnostic predictor for pleural effusion and/or ascites: external validation and clinical application. AB - BACKGROUND: The Dengue Score is a model for predicting pleural effusion and/or ascites and uses the hematocrit (Hct), albumin concentration, platelet count and aspartate aminotransferase (AST) ratio as independent variables. As this metric has not been validated, we conducted a study to validate the Dengue Score and assess its clinical application. METHODS: A retrospective study was performed at a private hospital in Jakarta, Indonesia. Patients with dengue infection hospitalized from January 2011 through March 2016 were included. The Dengue Score was calculated using four parameters: Hct increase>=15.1%, serum albumin<=3.49 mg/dL, platelet count<=49,500/MUL and AST ratio >= 2.51. Each parameter was scored as 1 if present and 0 if absent. To validate the Dengue Score, goodness-of fit was used to assess calibration, and the area under the receiver operating characteristic curve (AROC) was used to assess discrimination. Associations between clinical parameters and Dengue Score groups were determined by bivariate analysis. RESULTS: A total of 207 patients were included in this study. The calibration of the Dengue Score was acceptable (Hosmer-Lemeshow test, p = 0.11), and the score's discriminative ability was good (AROC = 0.88 (95% CI: 0.83 0.92)). At a cutoff of >=2, the Dengue Score had a positive predictive value (PPV) of 79.03% and a negative predictive value (NPV) of 90.36% for the diagnostic prediction of pleural effusion and/or ascites. Compared with the Dengue Score <= 1 group, the Dengue Score = 2 group was significantly associated with hemoconcentration> 20% (p = 0.029), severe thrombocytopenia (p = 0.029), and increased length of hospital stay (p = 0.003). Compared with the Dengue Score = 2 group, the Dengue Score >= 3 group was significantly associated with hemoconcentration> 20% (p = 0.001), severe thrombocytopenia (p = 0.024), severe dengue (p = 0.039), and increased length of hospital stay (p = 0.011). CONCLUSION: The Dengue Score performed well and can be used in daily practice to help clinicians identify patients who have plasma leakage associated with severe dengue. PMID- 29471787 TI - Evolutionary and expression analyses of soybean basic Leucine zipper transcription factor family. AB - BACKGROUND: Soybean, a major legume crop native to East Asia, presents a wealth of resources for utilization. The basic leucine zipper (bZIP) transcription factors play important roles in various biological processes including developmental regulation and responses to environmental stress stimuli. Currently, little information is available regarding the bZIP family in the legume crop soybean. RESULTS: Using a genome-wide domain analysis, we identified 160 GmbZIP genes in soybean genome, named from GmbZIP1 to GmbZIP160. These 160GmbZIP genes, distributed unevenly across 20 chromosomes, were grouped into 12 subfamilies based on phylogenetic analysis. Gene structure and conserved motif analyses showed that GmbZIP within the same subfamily shared similar intron-exon organizations and motif composition. Syntenic and phylogenetic analyses identified 40 Arabidopsis bZIP genes and 83 soybean bZIP genes as orthologs. By investigating the expression profiling of GmbZIP in different tissues and under drought and flooding stresses, we showed that a majority of GmbZIP (83.44%) exhibited transcript abundance in all examined tissues and 75.6% displayed transcript changes after drought and flooding treatment, suggesting that GmbZIP may play a broad role in soybean development and response to water stress. CONCLUSIONS: One hundred sixty GmbZIP genes were identified in soybean genome. Our results provide insights for the evolutionary history of bZIP family in soybean and shed light on future studies on the function of bZIP genes in response to water stress in soybean. PMID- 29471788 TI - Modelling physiological and pathological conditions to study pericyte biology in brain function and dysfunction. AB - BACKGROUND: Brain pericytes ensheathe the endothelium and contribute to formation and maintenance of the blood-brain-barrier. Additionally, pericytes are involved in several aspects of the CNS immune response including scarring, adhesion molecule expression, chemokine secretion, and phagocytosis. In vitro cultures are routinely used to investigate these functions of brain pericytes, however, these are highly plastic cells and can display differing phenotypes and functional responses depending on their culture conditions. Here we sought to investigate how two commonly used culture media, high serum containing DMEM/F12 and low serum containing Pericyte Medium (ScienCell), altered the phenotype of human brain pericytes and neuroinflammatory responses. METHODS: Pericytes were isolated from adult human brain biopsy tissue and cultured in DMEM/F12 (D-pericytes) or Pericyte Medium (P-pericytes). Immunocytochemistry, qRT-PCR, and EdU incorporation were used to determine how this altered their basal phenotype, including the expression of pericyte markers, proliferation, and cell morphology. To determine whether culture media altered the inflammatory response in human brain pericytes, immunocytochemistry, qRT-PCR, cytometric bead arrays, and flow cytometry were used to investigate transcription factor induction, chemokine secretion, adhesion molecule expression, migration, phagocytosis, and response to inflammatory-related growth factors. RESULTS: P-pericytes displayed elevated proliferation and a distinct bipolar morphology compared to D-pericytes. Additionally, P-pericytes displayed lower expression of pericyte-associated markers NG2, PDGFRbeta, and fibronectin, with notably lower alphaSMA, CD146, P4H and desmin, and higher Col-IV expression. Nuclear NF-kB translocation in response to IL-1beta stimulation was observed in both cultures, however, P-pericytes displayed elevated expression of the transcription factor C/EBPdelta, and lower expression of the adhesion molecule ICAM-1. P-pericytes displayed elevated phagocytic and migratory ability. Both cultures responded similarly to stimulation by the growth factors TGFbeta1 and PDGF-BB. CONCLUSIONS: Despite differences in their phenotype and magnitude of response, both P-pericytes and D pericytes responded similarly to all examined functions, indicating that the neuroinflammatory phenotype of these cells is robust to culture conditions. PMID- 29471789 TI - Melanin-embedded materials effectively remove hexavalent chromium (CrVI) from aqueous solution. AB - BACKGROUND: Currently, it is recognized that water polluted with toxic heavy metal ions may cause serious effects on human health. Therefore, the development of new materials for effective removal of heavy metal ions from water is still a widely important area. Melanin is being considered as a potential material for removal of heavy metal from water. METHODS: In this study, we synthesized two melanin-embedded beads from two different melanin powder sources and named IMB (Isolated Melanin Bead originated from squid ink sac) and CMB (Commercial Melanin Bead originated from sesame seeds). These beads were of globular shape and 2-3 mm in diameter. We investigated and compared the sorption abilities of these two bead materials toward hexavalent-chromium (CrVI) in water. The isotherm sorption curves were established using Langmuir and Freundlich models in the optimized conditions of pH, sorption time, solid/liquid ratio, and initial concentration of CrVI. The FITR analysis was also carried out to show the differences in surface properties of these two beads. RESULTS: The optimized conditions for isotherm sorption of CrVI on IMB/CMB were set at pH values of 2/2, sorption times of 90/300 min, and solid-liquid ratios of 10/20 mg/mL. The maximum sorption capacities calculated based on the Langmuir model were 19.60 and 6.24 for IMB and CMB, respectively. However, the adsorption kinetic of CrVI on the beads fitted the Freundlich model with R2 values of 0.992 for IMB and 0.989 for CMB. The deduced Freundlich constant, 1/n, in the range of 0.2-0.8 indicated that these beads are good adsorption materials. In addition, structure analysis data revealed great differences in physical and chemical properties between IMB and CMB. Interestingly, FTIR analysis results showed strong signals of -OH (3295.35 cm- 1) and -C=O (1608.63 cm- 1) groups harboring on the IMB but not CMB. Moreover, loading of CrVI on the IMB caused a shift of broad peaks from 3295.35 cm- 1 and 1608.63 cm- 1 to 3354.21 cm- 1 and 1597.06 cm- 1, respectively, due to OH and -C=O stretching. CONCLUSIONS: Taken together, our study suggests that IMB has great potential as a bead material for the elimination of CrVI from aqueous solutions and may be highly useful for water treatment applications. PMID- 29471790 TI - Gene expression correlated with delay in shell formation in larval Pacific oysters (Crassostrea gigas) exposed to experimental ocean acidification provides insights into shell formation mechanisms. AB - BACKGROUND: Despite recent work to characterize gene expression changes associated with larval development in oysters, the mechanism by which the larval shell is first formed is still largely unknown. In Crassostrea gigas, this shell forms within the first 24 h post fertilization, and it has been demonstrated that changes in water chemistry can cause delays in shell formation, shell deformations and higher mortality rates. In this study, we use the delay in shell formation associated with exposure to CO2-acidified seawater to identify genes correlated with initial shell deposition. RESULTS: By fitting linear models to gene expression data in ambient and low aragonite saturation treatments, we are able to isolate 37 annotated genes correlated with initial larval shell formation, which can be categorized into 1) ion transporters, 2) shell matrix proteins and 3) protease inhibitors. Clustering of the gene expression data into co-expression networks further supports the result of the linear models, and also implies an important role of dynein motor proteins as transporters of cellular components during the initial shell formation process. CONCLUSIONS: Using an RNA Seq approach with high temporal resolution allows us to identify a conceptual model for how oyster larval calcification is initiated. This work provides a foundation for further studies on how genetic variation in these identified genes could affect fitness of oyster populations subjected to future environmental changes, such as ocean acidification. PMID- 29471791 TI - Systemic fluoroquinolone prescriptions for hospitalized children in Belgium, results of a multicenter retrospective drug utilization study. AB - BACKGROUND: Fluoroquinolones (FQ) are increasingly prescribed for children, despite being labeled for only a limited number of labeled pediatric indications. In this multicenter retrospective drug utilization study, we analyzed indications for systemic FQ prescriptions in hospitalized children and the appropriateness of the prescribed dose. METHODS: Using data obtained from electronic medical files, the study included all children who received a systemic FQ prescription in two Belgian university children's hospitals between 2010 and 2013. Two authors reviewed prescribed daily doses. Univariate and multivariate logistic regression models were used to analyze risk factors for inadequately dosing. Results262 FQ prescriptions for individual patients were included for analysis. 16.8% of these prescriptions were for labeled indications, and 35.1% were guided by bacteriological findings. Prescribed daily dose was considered to be inappropriate in 79 prescriptions (30.2%). Other FQ than ciprofloxacin accounted for 9 prescriptions (3.4%), of which 8 were correctly dosed. Underdosing represented 45 (56.9%) dosing errors. Infants and preschool children were at particular risk for dosing errors, with associated adjusted OR of 0.263 (0.097 0.701) and 0.254 (0.106-0.588) respectively. CONCLUSIONS: FQ were often prescribed off-label and not guided by bacteriological findings in our study population. Dosing errors were common, particularly in infants and preschool children. FQ prescriptions for children should be improved by specific pediatric antimicrobial stewardship teams. Furthermore, pharmacokinetic studies should optimise dosing recommendations for children. PMID- 29471792 TI - Inpatient falls in older adults: a cohort study of antihypertensive prescribing pre- and post-fall. AB - BACKGROUND: Falls are common during hospital admissions and may occur more frequently in patients who are taking antihypertensive medications, particularly in the context of normal to low blood pressure. The review and adjustment of these medications is an essential aspect of the post-fall assessment and should take place as soon as possible after the fall. Our aim was to investigate whether appropriate post-fall adjustments of antihypertensive medications are routinely made in a large National Health Service (NHS) Trust. METHODS: Inpatient records over an eight-month period were captured from an electronic prescribing system to identify older adults (>=80 years old) with normal/low blood pressures (< 140 mmHg systolic) who had a documented inpatient fall as these patients were considered to be at high risk of further falls. Prescribed antihypertensive medication on admission was then compared with the post-fall (within 24 h after the fall) and discharge prescriptions. RESULTS: A total of 146 patients were included in the analysis. Of those, 120 patients (82%) were taking the same number of antihypertensive medications in the 24 h after the fall as they were before; only 19 patients (13%) had a reduction in the number of medications and seven patients (5%) had an increase in medications during that period. Only 9% of the antihypertensive classes assessed were either stopped or reduced in dose immediately post-fall. In addition, 11 new antihypertensives were prescribed at this time. At discharge, half of the patients (n = 73) remained on the same number of antihypertensive medication as on admission, 51 patients (35%) were on fewer antihypertensives and 22 (15%) were on more. Additionally, no changes were made to individual antihypertensives in 49% of prescriptions; 34% were stopped or reduced in dose but 38 new agents were started by the time of discharge. Angiotensin converting enzyme inhibitors and angiotensin II receptor blockers (ACEi/ARB) were the class of medications most commonly stopped or reduced (51%). CONCLUSIONS: Antihypertensive prescriptions are frequently unchanged after an inpatient fall. Routine medication review needs to be part of post-fall assessments in hospital to reduce the risk of further falls. PMID- 29471793 TI - Factors associated with the time to cessation of breastfeeding among mothers who have index children aged two to three years in Debre Markos, northwest Ethiopia: a retrospective follow up study. AB - BACKGROUND: Breastfeeding of children, which needs to continue until two years and beyond, is one of the essential requirements for child survival. However, in Ethiopia there is scarcity of literatures on the duration of breastfeeding. Therefore, the aim of this study was to assess the rate of cessation of breastfeeding among mothers with index children aged 2 to 3 years, northwest Ethiopia. METHODS: A retrospective follow-up study was conducted at Debre Markos town from March 1, 2014 to March 30, 2016. A total of 500 mother-child pairs were selected using the systematic random sampling method by moving from house to house with an interval of three eligible houses. A structured questionnaire was used to collect data. The Cox regression model was employed to identify the predictors of breastfeeding cessation. RESULTS: The proportion of women breastfeeding until 2 years was 13.70 per 1000 person- months. HIV-positive mothers decreased the time of breastfeeding by 3.4 times compared to HIV-negative mothers (AHR = 3.41, 95% CI: 1.96, 5.94). Government employee mothers decreased the time of breastfeeding by 2.8 times compared to housewives (AHR = 2.8, 95% CI: 1.80, 4.40).Better education increased the time of breastfeeding (AHR = 0.45, 95% CI: 0.24, 0.58). Number of children, family income, and place of delivery were the other significant predictors of time to cessation of breastfeeding (p < 0.05). CONCLUSION: In this study, the rate of cessation of breastfeeding was good. HIV negative mothers, government employment, number of children, place of delivery, and family monthly income were significant predictors to the time of breastfeeding cessation. Therefore, family planning and breastfeeding education in health institutions are essential to increase breastfeeding duration. PMID- 29471794 TI - LGR5 overexpression confers poor relapse-free survival in breast cancer patients. AB - BACKGROUND: Cancer stem cells (CSCs) are believed to promote the malignant transformation of breast cancer via multiple signaling pathways, including the Wnt/beta-catenin pathway. Leucine-rich repeat-containing G protein-coupled receptor 5 (LGR5) has been identified as a CSC-associated Wnt-regulated target gene, but its clinical significance in the context of breast cancer remains elusive. Therefore, the purpose of this study was to investigate the clinical significance of the LGR5-beta-catenin axis in breast cancer. METHODS: Breast cancer tissue blocks from 126 patients were used to construct a tissue microarray (TMA). Histopathological and clinical data including age; tumor size; estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) level; tumor grade; lymph node (LN) status; and survival were obtained from the cancer registry database and patients' medical records. Tissue on the breast TMA was scored for LGR5 and beta-catenin expression using semi quantitative immunohistochemical (IHC) staining. We also analyzed LGR5 expression in cellular datasets available through ONCOMINE, a web-based cancer microarray database. RESULTS: Immunohistochemical staining revealed that 58 tumors (46%) exhibited high LGR5 expression, whereas 56 tumors (47%) displayed high beta catenin expression. High levels of LGR5 expression were significantly associated with tumor size (p = 0.002), LN metastasis status (p = 0.044), and triple negative breast cancer (p = 0.029), consistent with our findings from the ONCOMINE database. In addition, we also found that beta-catenin -expressing breast cancers were positive correlated with HER2 overexpression. Finally, with respect to clinical outcomes, patients with high levels of LGR5-beta-catenin axis expression exhibited poorer relapse-free survival (RFS) compared to patients with low levels of LGR5-beta-catenin axis expression (p = 0.027). CONCLUSION: LGR5 overexpression was significantly associated with high T stage and LN metastasis status. High LGR5 expression was also associated with reduced RFS, indicating that LGR5 may represent a promising prognostic marker for breast cancer patients. PMID- 29471795 TI - Superficial punctate keratopathy in a pediatric patient was related to adenoid hypertrophy and obstructive sleep apnea syndrome: a case report. AB - BACKGROUND: Known causes of superficial punctuate keratopathy (SPK) in children include entropion, viral infection, blepharokeratoconjunctivitis (BKC), and toxicity of eye drops. However, there are some SPK patients whose causes could not be identified well. Herein, we describe the history, diagnosis, treatment, and prognosis of a rare case. CASE PRESENTATION: To report a case of superficial punctate keratopathy (SPK) which coexisted with floppy eyelid syndrome (FES) and presented as intermittent red eye and blurred vision in an 11-year-old boy who slept in the prone position. His condition did not improve despite treatment with topical antibiotics (levofloxacin, tobramycin), steroid eye drops (prednisolone), and artificial tears. The patient was diagnosed with tonsil hypertrophy and nasopharyngeal adenoid hypertrophy and obstructive sleep apnea syndrome (OSAS). He underwent tonsillectomy and adenoidectomy. Then he started sleeping in the supine position postoperatively. The SPK, red eye and blurred vision completely resolved after surgery without additional treatment. The corneal sensation also recovered gradually during the next 7 years. However, the floppy eyelid did not resolve. CONCLUSION: Recurrent SPK of childhood might be related to tonsil hypertrophy, adenoid hypertrophy and OSAS, which can be rehabilitated by a surgical approach. PMID- 29471796 TI - Impact of pulsed xenon ultraviolet disinfection on surface contamination in a hospital facility's expressed human milk feed preparation area. AB - BACKGROUND: Expressed human milk (EHM) feed preparation areas represent a potential source of unintentional nosocomial infection. Daily disinfection of environmental surfaces remains an essential intervention to mitigate nosocomial infections. The inefficiency of conventional cleaning and disinfection contributes to an increased risk for the acquisition of multi-drug resistant pathogens. "Non touch" technologies such as the pulsed xenon ultraviolet (PX-UVD) light device have documented sustained reduction in surface bacterial colonization and reduced cross contamination. METHODS: The impact of a PX-UVD on surface colony forming units per square centimeter (cfu/cm2) in feed preparation areas was evaluated following its implementation as standard care. A quasi experimental study was performed documenting bacterial colonization from 6 high risk feed preparation areas in a community care hospital in South Africa. Pre and post conventional cleaning neutralizing rinse swabs were collected fortnightly over a 16 week control period prior to the introduction of the PX-UVD and compared to a matching set of samples for the PX-UVD period. RESULTS: A 90% reduction in total surface bioburden was noted from the control period (544 cfu/cm2) compared to the corresponding PX-UVD period (50 cfu/cm2). Sub -analysis of both the Pre-clean Control: Pre-clean PX-UVD counts as well as the Post-clean Control: Post-clean PX-UVD counts noted significant improvements (p < 0.001). A statistically significant improvement was noted between pre-and post-cleaning total surface bioburden following exposure to the PX-UVD (p = 0.0004). The introduction of the PX-UVD was associated with a sustained reduction in the pre clean bioburden counts with a risk trend (per week) 0.19, (95% CI [0.056, 0.67], p = 0.01). DISCUSSION: The use of a PX-UVD as adjunct to standard cleaning protocols was associated with a significant decrease in surface bioburden. The study demonstrated the inefficiency of conventional cleaning. Persistence of potentially pathological species in both periods highlights current health sector challenges. PMID- 29471797 TI - Exercise reduces body fat and improves insulin sensitivity and pancreatic beta cell function in overweight and obese male Taiwanese adolescents. AB - BACKGROUND: Improvements in insulin resistance and pancreatic beta-cell function have been shown following exercise in adults with obesity; however, few adolescent-based studies have been conducted. This study examined the impact of exercise training on body fat and insulin sensitivity and secretion in overweight and obese adolescents. METHODS: The effects of a 12-week exercise program on the parameters of adiposity and glucose homeostasis were investigated in 47 overweight and obese male adolescents. RESULTS: After the exercise training program, body weight, body mass index, waist circumference, and body fat were significantly decreased (P < 0.001). Improvements in insulin sensitivity (HOMA IR: 1.40 vs. 0.86, P < 0.001) and the disposition index (5.84 vs. 12.77, P < 0.001) were also observed. Compared to baseline, oral glucose tolerance tests showed reduced glucose and insulin levels at all time points following the exercise training (all P < 0.001). Subgroup analysis of overweight and obese adolescents with abnormal glucose tolerance revealed that there was no difference in plasma glucose levels as compared to the lean group. CONCLUSIONS: A 12-week exercise training is effective in reducing body fat and improving insulin sensitivity and secretion. In addition, the benefits of the exercise intervention were even experienced by those with impaired glucose tolerance. PMID- 29471798 TI - Different patterns of myopia prevalence and progression between internal migrant and local resident school children in Shanghai, China: a 2-year cohort study. AB - BACKGROUND: In 2010, there were ~ 36 million migrant children under 18 y old in China. This study compared patterns of myopia prevalence and progression between migrant and resident children. METHODS: Eight hundred forty-two migrant children from 2 migrant schools and 1081 from 2 local schools in Baoshan District, Shanghai, were randomly chosen. Baseline measurements were taken on children in grades one through four, and children in grades one and two were followed for 2 y. The children underwent comprehensive ophthalmic examinations, including cycloplegic refraction and axial length. The average time per week spent on homework and outdoor activities were investigated. RESULTS: Migrant children in grades one and two showed a lower myopia prevalence than resident children; however, from grades three to four, the prevalence accelerated and exceeded that of residents. In the follow-up, the myopia incidence did not significantly change from grades one to two in resident children but was significantly higher in grade two in migrant children. Correspondingly, for migrant children, increased progression of refraction and axial length was observed; however, it decreased in resident children. The average time spent on homework increased from grades two to three in parallel with the acceleration of myopia prevalence for migrant children; however, the time spent outdoors did not correspondingly change. CONCLUSION: The patterns of myopia prevalence and progression are different between migrant and non-migrant children. The acceleration of myopia in migrant children might be a result of a change in their environment, such as intensive education pressure.

PMID- 29471799 TI - "Not just another Wii training": a graded Wii protocol to increase physical fitness in adolescent girls with probable developmental coordination disorder-a pilot study. AB - BACKGROUND: Adolescents with low motor competence participate less in physical activity and tend to exhibit decreased physical fitness compared to their peers with high motor competence. It is therefore essential to identify new methods of enhancing physical fitness in this population. Active video games (AVG) have been shown to improve motor performance, yet investigations of its impact on physical fitness are limited. The objective of this study was to examine the impact of the graded Wii protocol in adolescent girls with probable Developmental Coordination Disorder (p-DCD). METHODS: A single-group pre-post design was conducted to assess the impact of a newly developed Wii protocol in adolescent girls attending school in a low income community of Cape Town, South Africa. Sixteen participants (aged 13-16 years) with p-DCD (<=16th percentile on the MABC-2 test) were recruited. Participants received 45 min Wii training for 14 weeks. Outcome measures included the six-minute walk distance and repeated sprint ability. Information on heart rate, enjoyment and perceived exertion ratings were also collected. RESULTS: Significant improvements in aerobic and anaerobic fitness were observed. The participants reported high enjoyment scores and low perceived exertion ratings. The graded Wii protocol was easily adaptable and required little resources (space, equipment and expertise) to administer. CONCLUSIONS: The findings provide preliminary evidence to support the use of the graded Wii protocol for promoting physical fitness in adolescent girls with p-DCD. Further studies are needed to confirm these results and to validate the clinical efficacy of the protocol in a larger sample with a more robust design. PMID- 29471801 TI - A maximum likelihood algorithm for reconstructing 3D structures of human chromosomes from chromosomal contact data. AB - BACKGROUND: The development of chromosomal conformation capture techniques, particularly, the Hi-C technique, has made the analysis and study of the spatial conformation of a genome an important topic in bioinformatics and computational biology. Aided by high-throughput next generation sequencing techniques, the Hi-C technique can generate genome-wide, large-scale intra- and inter-chromosomal interaction data capable of describing in details the spatial interactions within a genome. These data can be used to reconstruct 3D structures of chromosomes that can be used to study DNA replication, gene regulation, genome interaction, genome folding, and genome function. RESULTS: Here, we introduce a maximum likelihood algorithm called 3DMax to construct the 3D structure of a chromosome from Hi-C data. 3DMax employs a maximum likelihood approach to infer the 3D structures of a chromosome, while automatically re-estimating the conversion factor (alpha) for converting Interaction Frequency (IF) to distance. Our results show that the models generated by 3DMax from a simulated Hi-C dataset match the true models better than most of the existing methods. 3DMax is more robust to structural variability and noise. Compared on a real Hi-C dataset, 3DMax constructs chromosomal models that fit the data better than most methods, and it is faster than all other methods. The models reconstructed by 3DMax were consistent with fluorescent in situ hybridization (FISH) experiments and existing knowledge about the organization of human chromosomes, such as chromosome compartmentalization. CONCLUSIONS: 3DMax is an effective approach to reconstructing 3D chromosomal models. The results, and the models generated for the simulated and real Hi-C datasets are available here: http://sysbio.rnet.missouri.edu/bdm_download/3DMax/ . The source code is available here: https://github.com/BDM-Lab/3DMax . A short video demonstrating how to use 3DMax can be found here: https://youtu.be/ehQUFWoHwfo . PMID- 29471802 TI - The short-term economic burden of gestational diabetes mellitus in Italy. AB - BACKGROUND: The incidence of Gestational Diabetes Mellitus (GDM) is rising in all developed countries. This study aimed at assessing the short-term economic burden of GDM from the Italian healthcare system perspective. METHODS: A model was built over the last pregnancy trimester (i.e., from the 28th gestational week until childbirth included). The National Hospital Discharge Database (2014) was accessed to estimate delivery outcome probabilities and inpatient costs in GDM and normal pregnancies (i.e., euglycemia). International Classification of Disease-9th Revision-Clinical Modification (ICD9-CM) diagnostic codes and Diagnosis-Related Group (DRG) codes were used to identify GDM cases and different types of delivery (i.e., vaginal or cesarean) within the database. Neonatal outcomes probabilities were estimated from the literature and included macrosomia, hypoglycemia, hyperbilirubinemia, shoulder dystocia, respiratory distress, and brachial plexus injury. Additional data sources such as regional documents, official price and tariff lists, national statistics and expert opinion were used to populate the model. The average cost per case was calculated at national level to estimate the annual economic burden of GDM. One-way sensitivity analyses and Monte Carlo simulations were performed to quantify the uncertainty around base case results. RESULTS: The amount of pregnancies complicated by GDM in Italy was assessed at 54,783 in 2014 using a prevalence rate of 10.9%. The antenatal outpatient cost per case was estimated at ?43.7 in normal pregnancies compared to ?370.6 in GDM patients, which is equivalent to a weighted sum of insulin- (14%; ?1034.6) and diet- (86%; ?262.5) treated women's costs. Inpatient delivery costs were assessed at ?1601.6 and ?1150.3 for euglycemic women and their infants, and at ?1835.0 and ?1407.7 for GDM women and their infants, respectively. Thus, the overall cost per case difference between GDM and normal pregnancies was equal to ?817.8 (+ 29.2%), resulting in an economic burden of about ?44.8 million in 2014 at national level. Probabilistic sensitivity analysis yielded a cost per case difference ranging between ?464.9 and ?1164.8 in 80% of simulations. CONCLUSIONS: The economic burden of GDM in Italy is substantial even accounting for short-term medical costs only. Future research also addressing long-term consequences from a broader societal perspective is recommended. PMID- 29471803 TI - Divergence and evolution of cotton bHLH proteins from diploid to allotetraploid. AB - BACKGROUND: Polyploidy is considered a major driving force in genome expansion, yielding duplicated genes whose expression may be conserved or divergence as a consequence of polyploidization. RESULTS: We compared the genome sequences of tetraploid cotton (Gossypium hirsutum) and its two diploid progenitors, G. arboreum and G. raimondii, and found that the bHLH genes were conserved over the polyploidization. Oppositely, the expression of the homeolgous gene pairs was diversified. The biased homeologous proportion for bHLH family is significantly higher (64.6%) than the genome wide homeologous expression bias (40%). Compared with cacao (T. cacao), orthologous genes only accounted for a small proportion (41.7%) of whole cotton bHLHs family. The further Ks analysis indicated that bHLH genes underwent at least two distinct episodes of whole genome duplication: a recent duplication (1.0-60.0 million years ago, MYA, 0.005 < Ks < 0.312) and an old duplication (> 60.0 MYA, 0.312 < Ks < 3.0). The old duplication event might have played a key role in the expansion of the bHLH family. Both recent and old duplicated pairs (68.8%) showed a divergent expression profile, indicating specialized functions. The expression diversification of the duplicated genes suggested it might be a universal feature of the long-term evolution of cotton. CONCLUSIONS: Overview of cotton bHLH proteins indicated a conserved and divergent evolution from diploids to allotetraploid. Our results provided an excellent example for studying the long-term evolution of polyploidy. PMID- 29471804 TI - Genetic mapping and comparative genomics to inform restoration enhancement and culture of southern flounder, Paralichthys lethostigma. AB - BACKGROUND: Southern flounder, Paralichthys lethostigma, historically support a substantial fishery along the Atlantic and Gulf coasts of the southern United States. Low year-class strengths over the past few years in the western Gulf of Mexico have raised concern that spawning stocks may be overfished. Current management of the resource includes releasing hatchery-raised juveniles to restock bays and estuaries; additionally, there is a growing interest in the potential for commercial aquaculture of the species. Currently, genomic resources for southern flounder do not exist. Here, we used two hatchery-reared families and double-digest, restriction-site-associated DNA (ddRAD) sequencing to create a reduced-representation genomic library consisting of several thousand single nucleotide polymorphisms (SNPs) located throughout the genome. RESULTS: The relative position of each SNP-containing locus was determined to create a high density genetic map spanning the 24 linkage groups of the southern flounder genome. The consensus map was used to identify regions of shared synteny between southern flounder and seven other fish species for which genome assemblies are available. Finally, syntenic blocks were used to localize genes identified from transcripts in European flounder as potentially being involved in ecotoxicological and osmoregulatory responses, as well as QTLs associated with growth and disease resistance in Japanese flounder, on the southern flounder linkage map. CONCLUSIONS: The information provided by the linkage map will enrich restoration efforts by providing a foundation for interpreting spatial genetic variation within the species, ultimately furthering an understanding of the adaptive potential and resilience of southern flounder to future changes in local environmental conditions. Further, the map will facilitate the use of genetic markers to enhance restoration and commercial aquaculture. PMID- 29471805 TI - Single nucleotide polymorphisms in native South American Atlantic coast populations of smooth shelled mussels: hybridization with invasive European Mytilus galloprovincialis. AB - BACKGROUND: Throughout the world, harvesting of mussels Mytilus spp. is based on the exploitation of natural populations and aquaculture. Aquaculture activities include transfers of spat and live adult mussels between various geographic locations, which may result in large-scale changes in the world distribution of Mytilus taxa. Mytilus taxa are morphologically similar and difficult to distinguish. In spite of much research on taxonomy, evolution and geographic distribution, the native Mytilus taxa of the Southern Hemisphere are poorly understood. Recently, single nucleotide polymorphisms (SNPs) have been used to clarify the taxonomic status of populations of smooth shelled mussels from the Pacific coast of South America. In this paper, we used a set of SNPs to characterize, for the first time, populations of smooth shelled mussels Mytilus from the Atlantic coast of South America. RESULTS: Mytilus spp. samples were collected from eastern South America. Six reference samples from the Northern Hemisphere were used: Mytilus edulis from USA and Northern Ireland, Mytilus trossulus from Canada, and Mytilus galloprovincialis from Spain and Italy. Two other reference samples from the Southern Hemisphere were included: M. galloprovincialis from New Zealand and Mytilus chilensis from Chile. Fifty-five SNPs were successfully genotyped, of which 51 were polymorphic. Population genetic analyses using the STRUCTURE program revealed the clustering of eight populations from Argentina (Mytilus platensis) and the clustering of the sample from Ushuaia with M. chilensis from Chile. All individuals in the Puerto Madryn (Argentina) sample were identified as M. platensis * M. galloprovincialis F2 (88.89%) hybrids, except one that was classified as Mediterranean M. galloprovincialis. No F1 hybrids were observed. CONCLUSIONS: We demonstrate that M. platensis (or Mytilus edulis platensis) and M. chilensis are distinct native taxa in South America, which indicates that the evolutionary histories of Mytilus taxa along the Atlantic and Pacific coasts differ. M. platensis is endangered by hybridization with M. galloprovincialis that was introduced from Europe into the Puerto Madryn area in Argentina, presumably by accidental introduction via ship traffic. We confirm the occurrence of a native M. chilensis population in southern Argentina on the coast of Patagonia. PMID- 29471806 TI - Variation of polypharmacy in older primary care attenders occurs at prescriber level. AB - BACKGROUND: Polypharmacy is particularly important in older persons as they are more likely to experience adverse events compared to the rest of the population. Despite the relevance, there is a lack of studies on the possible association of patient, prescriber and practice characteristics with polypharmacy. Thus, the aim of this study was to determine the rate of polypharmacy among older persons attending public and private primary care clinics, and its association with patient, prescriber and practice characteristics. METHODS: We used data from The National Medical Care Survey (NMCS), a national cross-sectional survey of patients' visits to primary care clinics in Malaysia. A weighted total of 22,832 encounters of patients aged >=65 years were analysed. Polypharmacy was defined as concomitant use of five medications and above. Multilevel logistic regression was performed to examine the association of polypharmacy with patient, prescriber and practice characteristics. RESULTS: A total of 20.3% of the older primary care attenders experienced polypharmacy (26.7%% in public and 11.0% in private practice). The adjusted odds ratio (OR) of polypharmacy were 6.37 times greater in public practices. Polypharmacy was associated with patients of female gender (OR 1.49), primary education level (OR 1.61) and multimorbidity (OR 14.21). The variation in rate of polypharmacy was mainly found at prescriber level. CONCLUSION: Polypharmacy is common among older persons visiting primary care practices. Given the possible adverse outcomes, interventions to reduce the burden of polypharmacy are best to be directed at individual prescribers. PMID- 29471807 TI - The treatment of malignant glaucoma in nanophthalmos: a case report. AB - BACKGROUND: The management of eyes with nanophthalmos is a dilemma for ophthalmologists due to various complications, especial the eye with malignant glaucoma. We report a case of effective treatment for malignant glaucoma in nanophthalmos. CASE PRESENTATION: An 82-year-old man was performed phacoemulsification in the right eye with normal ocular pressure and nanophthalmos. The surgery was uneventful: an intraocular lens (IOL) was placed and centered in the capsular bag. 2 months later, the patient presented with malignant glaucoma, and the intraocular pressure fluctuated between 18.6 mmHg and 30.8 mmHg with antiglaucoma medications. The patient did not respond to surgical peripheral iridotomy and goniosynechialysis. Then a single treatment with laser peripheral lens posterior capsulotomy and vitreous anterior membranectomy was performed. The intraocular pressure normalized, and the anterior chamber deepened within 24 h. The patient's condition remained stable for 9 months with no further treatment, and his Snellen corrected distance visual acuity was 20/50. The left eye of this patient was treated by combined surgery including phacoemulsification, IOL implantation, anterior vitrectomy, surgical peripheral iridotomy (PI), and goniosynechialysis. No intraoperative or postoperative complications were observed. CONCLUSIONS: This case suggests that it is essential to choose a suitable treatment for nanophthalmos patients to deal with malignant glaucoma and to reduce the incidence of malignant glaucoma. PMID- 29471808 TI - Whole genome duplications have provided teleosts with many roads to peptide loaded MHC class I molecules. AB - BACKGROUND: In sharks, chickens, rats, frogs, medaka and zebrafish there is haplotypic variation in MHC class I and closely linked genes involved in antigen processing, peptide translocation and peptide loading. At least in chicken, such MHCIa haplotypes of MHCIa, TAP2 and Tapasin are shown to influence the repertoire of pathogen epitopes being presented to CD8+ T-cells with subsequent effect on cell-mediated immune responses. RESULTS: Examining MHCI haplotype variation in Atlantic salmon using transcriptome and genome resources we found little evidence for polymorphism in antigen processing genes closely linked to the classical MHCIa genes. Looking at other genes involved in MHCI assembly and antigen processing we found retention of functional gene duplicates originating from the second vertebrate genome duplication event providing cyprinids, salmonids, and neoteleosts with the potential of several different peptide-loading complexes. One of these gene duplications has also been retained in the tetrapod lineage with orthologs in frogs, birds and opossum. CONCLUSION: We postulate that the unique salmonid whole genome duplication (SGD) is responsible for eliminating haplotypic content in the paralog MHCIa regions possibly due to frequent recombination and reorganization events at early stages after the SGD. In return, multiple rounds of whole genome duplications has provided Atlantic salmon, other teleosts and even lower vertebrates with alternative peptide loading complexes. How this affects antigen presentation remains to be established. PMID- 29471809 TI - Body mass index and lung cancer risk: a pooled analysis based on nested case control studies from four cohort studies. AB - BACKGROUND: Obesity has been proposed as a potential protective factor against lung cancer. We examined the association between BMI and lung cancer risk in a pooled analysis based on nested case-control studies from four cohort studies. METHODS: A case-control study was nested within four cohorts in USA, Europe, China and Singapore that included 4172 cases and 8471 control subjects. BMI at baseline was calculated as weight in kilograms divided by height in meters squared (kg/m2), and classified into 4 categories: underweight (BMI < 18.5), normal weight (18.5 <= BMI < 25), overweight (25 <= BMI < 30) and obese (>=30). Odds ratios (ORs) and 95% confidence intervals (CIs) for BMI-lung cancer associations were estimated using unconditional logistic regression, adjusting for potential confounders. RESULTS: Considering all participants, and using normal weight as the reference group, a decreased risk of lung cancer was observed for those who were overweight (OR 0.77, 95% CI: 0.68-0.86) and obese (OR 0.69, 95% CI: 0.59-0.82). In the stratified analysis by smoking status, the decreased risk for lung cancer was observed among current, former and never smokers (P for interaction 0.002). The adjusted ORs for overweight and obese groups were 0.79 (95% CI: 0.68-0.92) and 0.75 (95% CI: 0.60-0.93) for current smokers, 0.70 (95% CI: 0.53-0.93) and 0.55 (95% CI: 0.37-0.80) for former smokers, 0.77 (95% CI: 0.59-0.99), and 0.71 (95% CI: 0.44-1.14) for never smokers, respectively. While no statistically significant association was observed for underweight subjects who were current smokers (OR 1.24, 95% CI: 0.98 1.58), former smokers (OR 0.27, 95% CI: 0.12-0.61) and never smokers (OR 0.83, 95% CI: 0.5.-1.28). CONCLUSION: The results of this study provide additional evidence that obesity is associated with a decreased risk of lung cancer. Further biological studies are needed to address this association. PMID- 29471810 TI - Expression and function of microRNA-9 in the mid-hindbrain area of embryonic chick. AB - BACKGROUND: MiR-9 is a small non-coding RNA that is highly conserved between species and primarily expressed in the central nervous system (CNS). It is known to influence proliferation and neuronal differentiation in the brain and spinal cord of different vertebrates. Different studies have pointed to regional and species-specific differences in the response of neural progenitors to miR-9. METHODS: In ovo and ex ovo electroporation was used to overexpress or reduce miR 9 followed by mRNA in situ hybridisation and immunofluorescent stainings to evaluate miR- expression and the effect of changed miR-9 expression. RESULTS: We have investigated the expression and function of miR-9 during early development of the mid-hindbrain region (MH) in chick. Our analysis reveals a closer relationship of chick miR-9 to mammalian miR-9 than to fish and a dynamic expression pattern in the chick neural tube. Early in development, miR-9 is diffusely expressed in the entire brain, bar the forebrain, and it becomes more restricted to specific areas of the CNS at later stages. MiR-9 overexpression at HH9-10 results in a reduction of FGF8 expression and premature neuronal differentiation in the mid-hindbrain boundary (MHB). Within the midbrain miR-9 does not cause premature neuronal differentiation it rather reduces proliferation in the midbrain. CONCLUSION: Our findings indicate that miR-9 has regional specific effects in the developing mid-hindbrain region with a divergence of response of regional progenitors. PMID- 29471811 TI - Ethnic differences in infectious burden and the association with metabolic risk factors for cardiovascular disease: a cross-sectional analysis. AB - BACKGROUND: The burden of metabolic risk factors for cardiovascular disease (CVD), such as type 2 diabetes, elevated cholesterol and hypertension, is unequally distributed across ethnic groups. Recent findings suggest an association of infectious burden (IB) and metabolic risk factors, but data from ethnic groups are scarce. Therefore, we investigated ethnic differences in IB and its association with metabolic risk factors. METHODS: We included 440 Dutch, 320 Turkish and 272 Moroccan participants, 18-70 years, of the 2004 general health survey in Amsterdam, the Netherlands. IB was defined by seropositivity to the sum of 6 infections: Herpes Simplex Virus 1 and 2; Hepatitis A, B and C; and Helicobacter pylori. Associations between IB categories 4-6 (high), 3 (intermediate) and 0-2 (low) infections and metabolic risk factors were assessed by logistic regression. Finally, we determined the contribution of IB to the association between ethnicity and the metabolic risk factors by comparing adjusted logistic regression models with and without IB categories. RESULTS: A high IB was more frequently observed among the Turkish and Moroccans than among the Dutch. After adjustment for age, sex, ethnicity, educational level, physical activity and body mass index, high IB was associated with type 2 diabetes (odds ratio high vs low IB (OR) =2.14, 95%-confidence interval (CI) 1.05-4.36). The association was weaker and not statistically significant, for elevated cholesterol (OR = 1.39, 95%-CI 0.82-2.34) and hypertension (OR = 1.49, 95%-CI 0.88-2.51). IB attenuated ethnic differences particularly for type 2 diabetes. CONCLUSIONS: Our study showed that Turkish and Moroccan adults in Amsterdam have a higher IB than Dutch adults, which was associated with the differences in type 2 diabetes. Due to the cross-sectional nature of the study, we cannot draw a conclusions with regards to the time-sequence of cause and effect. Nevertheless, the findings ask for further research into the nature of association of IB with metabolic risk factors in a longitudinal setting. PMID- 29471812 TI - Effect of weight loss on circulating fatty acid profiles in overweight subjects with high visceral fat area: a 12-week randomized controlled trial. AB - BACKGROUND: Significant associations between visceral fat and alterations in plasma fatty acids have been identified in overweight individuals. However, there are scant data regarding the relationships of the visceral fat area (VFA) with the plasma fatty acid profiles and desaturase activities following weight loss. We investigated the effect of weight loss with mild calorie restriction on the circulating fatty acid profiles and desaturase activities in nondiabetic overweight subjects with high VFA. METHODS: Eighty overweight subjects with high VFA (L4 VFA >=100 cm2) were randomized into the 12-week mild-calorie-restriction (300 kcal/day) or control groups. RESULTS: Comparison of the percent of body weight changes between groups revealed that the weight-loss group had greater reductions in body weight. The VFA decreased by 17.7 cm2 from baseline in the weight-loss group (P < 0.001). At follow-up, the weight-loss group showed greater reductions in serum triglycerides, insulin, and HOMA-IR than the control group. Significantly greater reductions in total saturated fatty acids, palmitic acid, stearic acid, total monounsaturated fatty acids, palmitoleic acid, oleic acid, eicosadienoic acid, and dihomo-gamma-linolenic acid levels were detected in the weight-loss group compared with the control group after adjusting for baseline values. Following weight loss, C16 Delta9-desaturase activity was significantly decreased and Delta5-desaturase activity was significantly increased, and the changes were greater in the weight-loss group than in the control group. CONCLUSIONS: The results suggest that mild weight loss improves abdominal obesity, overall fatty acid profiles, and desaturase activities; therefore, mild calorie restriction has potential health benefits related to obesity-related diseases in overweight subjects with high VFA. TRIAL REGISTRATION: NCT02992639. Retrospectively registered 11 December 2016. PMID- 29471813 TI - Rural-urban and racial-ethnic differences in awareness of direct-to-consumer genetic testing. AB - BACKGROUND: Access to direct-to-consumer genetic testing services has increased in recent years. However, disparities in knowledge and awareness of these services are not well documented. We examined awareness of genetic testing services by rural/urban and racial/ethnic status. METHODS: Analyses were conducted using pooled cross-sectional data from 4 waves (2011-2014) of the Health Information National Trends Survey (HINTS). Descriptive statistics compared sample characteristics and information sources by rural/urban residence. Logistic regression was used to examine the relationship between geography, racial/ethnic status, and awareness of genetic testing, controlling for sociodemographic characteristics. RESULTS: Of 13,749 respondents, 16.7% resided in rural areas, 13.8% were Hispanic, and 10.1% were non-Hispanic black. Rural residents were less likely than urban residents to report awareness of genetic testing (OR = 0.74, 95% CI = 0.63-0.87). Compared with non-Hispanic whites, racial/ethnic minorities were less likely to be aware of genetic testing: Hispanic (OR = 0.68, 95% CI = 0.56-0.82); and non-Hispanic black (OR = 0.74, 95% CI = 0.61-0.90). CONCLUSIONS: Rural-urban and racial-ethnic differences exist in awareness of direct-to-consumer genetic testing. These differences may translate into disparities in the uptake of genetic testing, health behavior change, and disease prevention through precision and personalized medicine. PMID- 29471814 TI - Moral dilemmas and conflicts concerning patients in a vegetative state/unresponsive wakefulness syndrome: shared or non-shared decision making? A qualitative study of the professional perspective in two moral case deliberations. AB - BACKGROUND: Patients in a vegetative state/ unresponsive wakefulness syndrome (VS/UWS) pose ethical dilemmas to those involved. Many conflicts occur between professionals and families of these patients. In the Netherlands physicians are supposed to withdraw life sustaining treatment once recovery is not to be expected. Yet these patients have shown to survive sometimes for decades. The role of the families is thought to be important. The aim of this study was to make an inventory of the professional perspective on conflicts in long-term care of patients in VS/UWS. METHODS: A qualitative study of transcripts on 2 Moral Deliberations (MD's) in 2 cases of patients in VS/UWS in long-term care facilities. RESULTS: Six themes emerged: 1) Vision on VS/UWS; 2) Treatment and care plan; 3) Impact on relationships; 4) Feelings/attitude; 5) Communication; 6) Organizational aspects. These themes are related to professionals and to what families had expressed to the professionals. We found conflicts as well as contradictory feelings and thoughts to be a general feature in 4 of these themes, both in professionals and families. Conflicts were found in several actors: within families concerning all 6 themes, in nurse teams concerning the theme treatment and care plan, and between physicians concerning all 6 themes. CONCLUSIONS: Different visions, different expectations and hope on recovery, deviating goals and contradictory feelings/thoughts in families and professionals can lead to conflicts over a patient with VS/UWS. Key factors to prevent or solve such conflicts are a carefully established diagnosis, clarity upon visions, uniformity in treatment goals and plans, an open and empathic communication, expertise and understanding the importance of contradictory feelings/thoughts. Management should bridge conflicts and support their staff, by developing expertise, by creating stability and by facilitating medical ethical discourses. Shared compassion for the patient might be a key to gain trust and bridge the differences from non-shared to shared decision making. PMID- 29471815 TI - Glucocorticosteroids and ciclosporin do not significantly impact canine cutaneous microbiota. AB - BACKGROUND: As prednisone and ciclosporin can have immunosuppressive effects and have been considered potential predisposing factors for skin infections, we investigated the impact of these drugs on the diversity of the cutaneous microbiota, the abundance of Malassezia and infection with Papillomaviruses. RESULTS: Six atopic, asymptomatic Maltese-beagle dogs were treated with ciclosporin for one month and then with prednisone for another month, with a one month wash-out between treatments. The dogs were sampled on the abdomen and pinna before and after each treatment using a swab. Samples for Papillomavirus detection were obtained with cytobrush sticks. The bacterial microbiota was characterized using 16S amplicon high-throughput sequencing. Malassezia populations were quantified with nested real-time PCR targeting the ribosomal internal transcribed spacer 1. The diversity and composition of cutaneous microbiota was not impacted in a detectable manner by any of the treatments. As observed for the bacterial microbiota, Malassezia populations were not affected by treatment. Three dogs were positive for Papillomavirus at more than one timepoint, but an association with treatment was not apparent. CONCLUSIONS: Ciclosporin and prednisone at doses used for the treatment of atopic dermatitis do not impact the canine cutaneous microbiota in a detectable manner. PMID- 29471817 TI - Health care quality measures for children and adolescents in Foster Care: feasibility testing in electronic records. AB - BACKGROUND: Preventive quality measures for the foster care population are largely untested. The objective of the study is to identify healthcare quality measures for young children and adolescents in foster care and to test whether the data required to calculate these measures can be feasibly extracted and interpreted within an electronic health records or within the Statewide Automated Child Welfare Information System. METHODS: The AAP Recommendations for Preventive Pediatric Health Care served as the guideline for determining quality measures. Quality measures related to well child visits, developmental screenings, immunizations, trauma-related care, BMI measurements, sexually transmitted infections and depression were defined. Retrospective chart reviews were performed on a cohort of children in foster care from a single large pediatric institution and related county. Data available in the Ohio Statewide Automated Child Welfare Information System was compared to the same population studied in the electronic health record review. Quality measures were calculated as observed (received) to expected (recommended) ratios (O/E ratios) to describe the actual quantity of recommended health care that was received by individual children. RESULTS: Electronic health records and the Statewide Automated Child Welfare Information System data frequently lacked important information on foster care youth essential for calculating the measures. Although electronic health records were rich in encounter specific clinical data, they often lacked custodial information such as the dates of entry into and exit from foster care. In contrast, Statewide Automated Child Welfare Information System included robust data on custodial arrangements, but lacked detailed medical information. Despite these limitations, several quality measures were devised that attempted to accommodate these limitations. CONCLUSIONS: In this feasibility testing, neither the electronic health records at a single institution nor the county level Statewide Automated Child Welfare Information System was able to independently serve as a reliable source of data for health care quality measures for foster care youth. However, the ability to leverage both sources by matching them at an individual level may provide the complement of data necessary to assess the quality of healthcare. PMID- 29471816 TI - Idiopathic pulmonary fibrosis: pathogenesis and management. AB - BACKGROUND: Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive disease characterized by the aberrant accumulation of fibrotic tissue in the lungs parenchyma, associated with significant morbidity and poor prognosis. This review will present the substantial advances achieved in the understanding of IPF pathogenesis and in the therapeutic options that can be offered to patients, and will address the issues regarding diagnosis and management that are still open. MAIN BODY: Over the last two decades much has been clarified about the pathogenic pathways underlying the development and progression of the lung scarring in IPF. Sustained alveolar epithelial micro-injury and activation has been recognised as the trigger of several biological events of disordered repair occurring in genetically susceptible ageing individuals. Despite multidisciplinary team discussion has demonstrated to increase diagnostic accuracy, patients can still remain unclassified when the current diagnostic criteria are strictly applied, requiring the identification of a Usual Interstitial Pattern either on high resolution computed tomography scan or lung biopsy. Outstanding achievements have been made in the management of these patients, as nintedanib and pirfenidone consistently proved to reduce the rate of progression of the fibrotic process. However, many uncertainties still lie in the correct use of these drugs, ranging from the initial choice of the drug, the appropriate timing for treatment and the benefit-risk ratio of a combined treatment regimen. Several novel compounds are being developed in the perspective of a more targeted therapeutic approach; in the meantime, the supportive care of these patients and their carers should be appropriately prioritized, and greater efforts should be made toward the prompt identification and management of relevant comorbidities. CONCLUSIONS: Building on the advances in the understanding of IPF pathobiology, the further investigation of the role of gene variants, epigenetic alterations and other molecular biomarkers reflecting disease activity and behaviour will hopefully enable earlier and more confident diagnosis, improve disease phenotyping and support the development of novel agents for personalized treatment of IPF. PMID- 29471818 TI - Adult Wilms tumor with inferior vena cava thrombus and distal deep vein thrombosis - a case report and literature review. AB - BACKGROUND: Adult Wilms tumor (WT, nephroblastoma) is a rare, but well-described renal neoplasm. Although inferior vena cava tumor thrombosis is present in up to 10% of Wilms tumors in childhood, only few cases of this clinical manifestation in adults have been reported. To the best of our knowledge, this is the first case of adult WT infiltrating into inferior vena cava (IVC) with concomitant distal deep vein thrombosis. CASE PRESENTATION: A 28-year-old male patient with gross hematuria and right flank pain was diagnosed with right kidney tumor penetrating to IVC. Preoperatively, acute distal thrombosis in inferior vena cava and lower extremities veins occurred. Right radical nephrectomy with tumor thrombectomy via cavotomy was performed. In order to prevent pulmonary embolism, IVC was ligated below left renal vein level. Histopathological examination revealed a triphasic nephroblastoma without anaplastic features. Postoperatively, patient was diagnosed with metastatic liver disease, which was treated with two lines of chemotherapy followed by radiotherapy with achievement of complete response. CONCLUSIONS: Adult WT occurs usually in young patients, under 40 years of age. Neoadjuvant chemotherapy proved to be effective in children, resulting with tumor shrinkage and venous tumor thrombus regression. Therefore, percutaneous biopsy should be always considered in young patients presenting with renal tumor invading venous system. IVC ligation is a safe treatment option in the event of complete inferior vena cava occlusion due to distal thrombosis concomitant to tumor thrombus, provided collateral venous pathways are well developed. PMID- 29471819 TI - Dengue periodic outbreaks and epidemiological trends in Nepal. AB - Dengue is a global health problem and expansion of its endemics towards new territories in the hilly regions in Nepal is a serious concern. It appeared as a new disease in Nepal in 2004 from Japanese traveler with sporadic cases every year and massive outbreaks in 2010, 2013 and 2016. The serotype was responsible for outbreak in particular year was dengue virus serotype-1 (DENV-1) in 2010, 2016; and DENV-2 in 2013. Nepal lacks basic health related infrastructure in rural areas and does not have a stringent health care policy. With severances of epidemic like dengue, a new surveillance or an upgrading of existing one are direly needed to better challenge the possible outbreaks. This review paper aims to explain the dengue trend in last one decade in Nepal and warrants concerted and timely public health interventions to minimize the deleterious effects of the disease. PMID- 29471820 TI - Directly mining a fungal thermostable alpha-amylase from Chinese Nong-flavor liquor starter. AB - BACKGROUND: Chinese Nong-flavor (NF) liquor is continuously and stably produced by solid-state fermentation technology for 1000 years, resulting in enrichment of special microbial community and enzymes system in its starter. Based on traditional culture-dependent methods, these functional enzymes are hardly obtained. According to our previous metatranscriptomic analysis, which identifies plenty of thermostable carbohydrate-active enzymes in NF liquor starter, the aim of this study is to provide a direct and efficient way to mine these thermostable enzymes. RESULTS: In present study, an alpha-amylase (NFAmy13A) gene, which showed the highest expression level of enzymes in starch degradation at high temperature stage (62 degrees C), was directly obtained by functional metatranscriptomics from Chinese Nong-flavor liquor starter and expressed in Pichia pastoris. NFAmy13A had a typical signal peptide and shared the highest sequence identity of 64% with alpha-amylase from Aspergillus niger. The recombinant enzyme of NFAmy13A showed an optimal pH at 5.0-5.5 and optimal temperature at 60 degrees C. NFAmy13A was activated and stabilized by Ca2+, and its half-lives at 60 and 70 degrees C were improved significantly from 1.5 and 0.4 h to 16 and 0.7 h, respectively, in the presence of 10 mM CaCl2. Meanwhile, Hg2+, Co2+ and SDS largely inhibited its activity. NFAmy13A showed the maximum activity on amylopectin, followed by various starches, amylose, glycogen, and pullulan, and its specificity activity on amylopectin was 200.4 U/mg. Moreover, this alpha-amylase efficiently hydrolyzed starches (from corn, wheat, and potato) at high concentrations up to 15 mg/ml. CONCLUSIONS: This study provides a direct way to mine active enzymes from man-made environment of NF liquor starter, by which a fungal thermostable alpha-amylase (NFAmy13A) is successfully obtained. The good characteristics of NFAmy13A in degrading starch at high temperature are consistent with its pivotal role in solid-state fermentation of NF liquor brewing. This work would stimulate mining more enzymes from NF liquor starter and studying their potentially synergistic roles in NF liquor brewing, thus paving the way toward the optimization of liquor production and improvement of liquor quality in future. PMID- 29471821 TI - Decision-making at the limit of viability: differing perceptions and opinions between neonatal physicians and nurses. AB - BACKGROUND: In the last 20 years, the chances for intact survival for extremely preterm infants have increased in high income countries. Decisions about withholding or withdrawing intensive care remain a major challenge in infants born at the limits of viability. Shared decision-making regarding these fragile infants between health care professionals and parents has become the preferred model today. However, there is an ongoing ethical debate on how decisions regarding life-sustaining treatment should be reached and who should have the final word when health care professionals and parents do not agree. We designed a survey among neonatologists and neonatal nurses to analyze practices, difficulties and parental involvement in end-of-life decisions for extremely preterm infants. METHODS: All 552 physicians and nurses with at least 12 months work experience in level III neonatal intensive care units (NICU) in Switzerland were invited to participate in an online survey with 50 questions. Differences between neonatologists and NICU nurses and between language regions were explored. RESULTS: Ninety six of 121 (79%) physicians and 302 of 431(70%) nurses completed the online questionnaire. The following difficulties with end-of-life decision-making were reported more frequently by nurses than physicians: insufficient time for decision-making, legal constraints and lack of consistent unit policies. Nurses also mentioned a lack of solidarity in our society and shortage of services for disabled more often than physicians. In the context of limiting intensive care in selected circumstances, nurses considered withholding tube feedings and respiratory support less acceptable than physicians. Nurses were more reluctant to give parents full authority to decide on the course of action for their infant. In contrast to professional category (nurse or physician), language region, professional experience and religion had little influence if any on the answers given. CONCLUSIONS: Physicians and nurses differ in many aspects of how and by whom end-of-life decisions should be made in extremely preterm infants. The divergencies between nurses and physicians may be due to differences in ethics education, varying focus in patient care and direct exposure to the patients. Acknowledging these differences is important to avoid potential conflicts within the neonatal team but also with parents in the process of end-of-life decision-making in preterm infants born at the limits of viability. PMID- 29471822 TI - Direct whole-genome sequencing of Plasmodium falciparum specimens from dried erythrocyte spots. AB - BACKGROUND: Plasmodium falciparum malaria remains a major health burden and genomic research represents one of the necessary approaches for continued progress towards malaria control and elimination. Sample acquisition for this purpose is troublesome, with the majority of malaria-infected individuals living in rural areas, away from main infrastructure and the electrical grid. The aim of this study was to describe a low-tech procedure to sample P. falciparum specimens for direct whole genome sequencing (WGS), without use of electricity and cold chain. METHODS: Venous blood samples were collected from malaria patients in Bandim, Guinea-Bissau and leukocyte-depleted using Plasmodipur filters, the enriched parasite sample was spotted on Whatman paper and dried. The samples were stored at ambient temperatures and subsequently used for DNA-extraction. Ratios of parasite:human content of the extracted DNA was assessed by qPCR, and five samples with varying parasitaemia, were sequenced. Sequencing data were used to analyse the sample content, as well as sample coverage and depth as compared to the 3d7 reference genome. RESULTS: qPCR revealed that 73% of the 199 samples were applicable for WGS, as defined by a minimum ratio of parasite:human DNA of 2:1. WGS revealed an even distribution of sequence data across the 3d7 reference genome, regardless of parasitaemia. The acquired read depths varied from 16 to 99*, and coverage varied from 87.5 to 98.9% of the 3d7 reference genome. SNP analysis of six genes, for which amplicon sequencing has been performed previously, confirmed the reliability of the WGS-data. CONCLUSION: This study describes a simple filter paper based protocol for sampling P. falciparum from malaria patients for subsequent direct WGS, enabling acquisition of samples in remote settings with no access to electricity. PMID- 29471823 TI - Unidimensional scales for fears of cancer recurrence and their psychometric properties: the FCR4 and FCR7. AB - BACKGROUND: The assessment of fear of recurrence (FCR) is crucial for understanding an important psychological state in patients diagnosed and treated for cancer. The study aim was to determine psychometric details of a seven question self-report scale (FCR7) and a short form (FCR4) based upon items already used in various extensive measures of FCR. METHODS: Two consecutive samples of patients (breast and colorectal) were recruited from a single specialist cancer centre. The survey instrument contained the FCR7 items, Hospital Anxiety and Depression Scale (HADS), and demographic details. Clinical information was obtained from patient hospital records. Statistical analyses were performed using classical test and item response theory approaches, to demonstrate unidimensional factor structure and testing key parameters. Construct validity was inspected through nomological and theoretical prediction. RESULTS: Internal consistency was demonstrated by alpha coefficients (FCR4: 0.93 and FCR7: 0.92). Both scales (FCR7 & FCR4) were associated with the HADs subscales as predicted. Patients who experienced chemotherapy, minor aches/pains, thought avoidance of cancer and high cancer risk belief were more fearful. Detailed inspection of item responses profile provided some support for measurement properties of scales. CONCLUSION: The internal consistency, and pattern of key associations and discriminability indices provided positive psychometric evidence for these scales. The brief measures of FCR may be considered for audit, screening or routine use in clinical service and research investigations. PMID- 29471824 TI - Perceived stress, reasons for and sources of stress among medical students at Rabigh Medical College, King Abdulaziz University, Jeddah, Saudi Arabia. AB - BACKGROUND: Medical students have high levels of stress that could be due to the daily life stressors and the extra stress of academic burden. The present study investigated the perceived stress level as well as the reasons and sources of stress among medical students at a comparatively newly established medical college affiliated with King Abdulaziz University (KAU), Jeddah, Saudi Arabia (SA). METHODS: The present study was carried out at Rabigh Medical College (RMC), KAU, Jeddah, and completed in 2015. The data was collected by an anonymous self administered questionnaire that has three components: a list of 33 items of probable stressors, perceived stress scale, and demographic information and academics. RESULTS: The response rate in our study was 86% (152/176), the mean age was 20.35 +/- 1.09, 77 (51%) were from preclinical years and 75 (49%) from clinical years. The mean PSS score among our participants was 28.5 +/- 3.8 with a median of 28.0 (IQR 26.0-31.0) and 59.2% of participants were stressed. The mean PSS score 30.6 +/- 4.4 for students with sibling > 5 was significantly higher as compared to the mean PSS score (27.9 +/- 3.3) for students with sibling <=5. Similarly, the mean PSS score (32.0 +/- 3.4) of students with often/always occurrence of psychosocial stressors was higher as compared to the mean PSS score (28.3 +/- 3.7) of those students with less than a frequent occurrence of stressors. Moreover, those students that were more stressed had lower marks in the last exam (< 80%) as compared to students with less stress who had higher marks (>=80%) (P < .05). Performance in practicals, examinations frequency, disappointment with the class lectures, lack of personal interest in medicine, lengthy academic curriculum/syllabus, worries about the future and periodic examinations performance were rated as severe. The logistic regression analysis showed that stress cases were linked with last exam marks [OR 1.26, 95% CI 0.64 2.48], number of siblings [OR 2.27, 95% CI 0.97-5.27], and academic stressor [OR 2.02, 95% CI 0.61-6.66] but no significant relationship was found. CONCLUSION: There were high-stress levels among the participants of this study, and the main stressors were academic-related. PMID- 29471825 TI - Finish line distinctness and accuracy in 7 intraoral scanners versus conventional impression: an in vitro descriptive comparison. AB - BACKGROUND: Several studies have evaluated accuracy of intraoral scanners (IOS), but data is lacking regarding variations between IOS systems in the depiction of the critical finish line and the finish line accuracy. The aim of this study was to analyze the level of finish line distinctness (FLD), and finish line accuracy (FLA), in 7 intraoral scanners (IOS) and one conventional impression (IMPR). Furthermore, to assess parameters of resolution, tessellation, topography, and color. METHODS: A dental model with a crown preparation including supra and subgingival finish line was reference-scanned with an industrial scanner (ATOS), and scanned with seven IOS: 3M, CS3500 and CS3600, DWIO, Omnicam, Planscan and Trios. An IMPR was taken and poured, and the model was scanned with a laboratory scanner. The ATOS scan was cropped at finish line and best-fit aligned for 3D Compare Analysis (Geomagic). Accuracy was visualized, and descriptive analysis was performed. RESULTS: All IOS, except Planscan, had comparable overall accuracy, however, FLD and FLA varied substantially. Trios presented the highest FLD, and with CS3600, the highest FLA. 3M, and DWIO had low overall FLD and low FLA in subgingival areas, whilst Planscan had overall low FLD and FLA, as well as lower general accuracy. IMPR presented high FLD, except in subgingival areas, and high FLA. Trios had the highest resolution by factor 1.6 to 3.1 among IOS, followed by IMPR, DWIO, Omnicam, CS3500, 3M, CS3600 and Planscan. Tessellation was found to be non-uniform except in 3M and DWIO. Topographic variation was found for 3M and Trios, with deviations below +/- 25 MUm for Trios. Inclusion of color enhanced the identification of the finish line in Trios, Omnicam and CS3600, but not in Planscan. CONCLUSIONS: There were sizeable variations between IOS with both higher and lower FLD and FLA than IMPR. High FLD was more related to high localized finish line resolution and non-uniform tessellation, than to high overall resolution. Topography variations were low. Color improved finish line identification in some IOS. It is imperative that clinicians critically evaluate the digital impression, being aware of varying technical limitations among IOS, in particular when challenging subgingival conditions apply. PMID- 29471826 TI - The family talk intervention in palliative care: a study protocol. AB - BACKGROUND: In palliative care contexts, support programs for families with a severely ill parent and minor children are few, and even fewer have been evaluated scientifically. The aims of this study are to examine feasibility and potential effects of a modified version of the Family Talk Intervention (FTI) in palliative care. METHODS: This ongoing family-centered intervention has a quasi experimental design comparing one intervention and one comparison group. The intervention includes severely ill parents who have minor children (aged 6-19 yrs) and are receiving advanced homecare in Stockholm, Sweden between March 2017 and March 2018. The main goal of the FTI is to support family communication through psycho-education and narrative theory. The modified FTI consists of six meetings with family members, and is held by two interventionists. Each family sets up needs-based goals for the intervention. For evaluation purposes, data are collected by questionnaire before the intervention, within two months after baseline, and one year after baseline. Interviews will be conducted within two months after FTI is completed. Notes taken by one of the interventionists during the family meetings will also be used. Questionnaire data analysis will focus on patterns over time using descriptive statistics. For interview data and notes, content analysis will be used. DISCUSSION: This study will add knowledge about palliative care for parents who have minor children. It will contribute by testing use of FTI in palliative care, and point out directions for future evaluations of FTI in palliative care settings. TRIAL REGISTRATION: ClinicalTrials.gov Identifier NCT03119545 , retrospectively registered in April 18, 2017. PMID- 29471828 TI - A Delphi study and ranking exercise to support commissioning services: future delivery of Thrombectomy services in England. AB - BACKGROUND: Intra-arterial thrombectomy is the gold standard treatment for large artery occlusive stroke. However, the evidence of its benefits is almost entirely based on trials delivered by experienced neurointerventionists working in established teams in neuroscience centres. Those responsible for the design and prospective reconfiguration of services need access to a comprehensive and complementary array of information on which to base their decisions. This will help to ensure the demonstrated effects from trials may be realised in practice and account for regional/local variations in resources and skill-sets. One approach to elucidate the implementation preferences and considerations of key experts is a Delphi survey. In order to support commissioning decisions, we aimed using an electronic Delphi survey to establish consensus on the options for future organisation of thrombectomy services among physicians with clinical experience in managing large artery occlusive stroke. METHODS: A Delphi survey was developed with 12 options for future organisation of thrombectomy services in England. A purposive sampling strategy established an expert panel of stroke physicians from the British Association of Stroke Physicians (BASP) Clinical Standards and/or Executive Membership that deliver 24/7 intravenous thrombolysis. Options with aggregate scores falling within the lowest quartile were removed from the subsequent Delphi round. Options reaching consensus following the two Delphi rounds were then ranked in a final exercise by both the wider BASP membership and the British Society of Neuroradiologists (BSNR). RESULTS: Eleven stroke physicians from BASP completed the initial two Delphi rounds. Three options achieved consensus, with subsequently wider BASP (97%, n = 43) and BSNR members (86%, n = 21) assigning the highest approval rankings in the final exercise for transferring large artery occlusive stroke patients to nearest neuroscience centre for thrombectomy based on local CT/CT Angiography. CONCLUSIONS: The initial Delphi rounds ensured optimal reduction of options by an expert panel of stroke physicians, while subsequent ranking exercises allowed remaining options to be ranked by a wider group of experts within stroke to reach consensus. The preferred implementation option for thrombectomy is investigating suspected acute stroke patients by CT/CT Angiography and secondary transfer of large artery occlusive stroke patients to the nearest neuroscience (thrombectomy) centre. PMID- 29471829 TI - Transcriptional profiles of different states of cancer stem cells in triple negative breast cancer. AB - Breast cancer stem cells (BCSCs) are thought to be responsible for tumor initiation, metastasis and relapse. Our group and others have described markers useful in isolating BCSCs just as aldehyde dehydrogenase positive (ALDH+) or CD24 CD44+. In fact, cells which simultaneously express both sets of markers have the highest tumor initiating capacity. Although the transcriptomic profile of cells expressing each BCSC marker alone has been reported, the profile of the most tumorigenic population expressing both sets of markers has not. Here we used the biomarker combination of ALDH and CD24/CD44 to sort four populations isolated from triple-negative breast cancer (TNBC) patient-derived xenografts, and performed whole-transcriptome sequencing on each population. We systematically compared the profiles of the three states of BCSCs (ALDH+CD24-CD44+, ALDH+non CD24-CD44+ and ALDH-CD24-CD44+) to that of the differentiated tumor cells (ALDH non-CD24-CD44+). For the first time, we compared the ALDH+CD24-CD44+ BCSCs with the other two BCSC populations. In ALDH+CD24-CD44+ BCSCs, we identified P4HA2, PTGR1 and RAB40B as potential prognostic markers, which were virtually related to the status of BCSCs and tumor growth in TNBC cells. PMID- 29471827 TI - Nuclear functions of mammalian MicroRNAs in gene regulation, immunity and cancer. AB - MicroRNAs (miRNAs) are endogenous non-coding RNAs that contain approximately 22 nucleotides. They serve as key regulators in various biological processes and their dysregulation is implicated in many diseases including cancer and autoimmune disorders. It has been well established that the maturation of miRNAs occurs in the cytoplasm and miRNAs exert post-transcriptional gene silencing (PTGS) via RNA-induced silencing complex (RISC) pathway in the cytoplasm. However, numerous studies reaffirm the existence of mature miRNA in the nucleus, and nucleus-cytoplasm transport mechanism has also been illustrated. Moreover, active regulatory functions of nuclear miRNAs were found including PTGS, transcriptional gene silencing (TGS), and transcriptional gene activation (TGA), in which miRNAs bind nascent RNA transcripts, gene promoter regions or enhancer regions and exert further effects via epigenetic pathways. Based on existing interaction rules, some miRNA binding sites prediction software tools are developed, which are evaluated in this article. In addition, we attempt to explore and review the nuclear functions of miRNA in immunity, tumorigenesis and invasiveness of tumor. As a non-canonical aspect of miRNA action, nuclear miRNAs supplement miRNA regulatory networks and could be applied in miRNA based therapies. PMID- 29471830 TI - Beyond coverage: improving the quality of antenatal care delivery through integrated mentorship and quality improvement at health centers in rural Rwanda. AB - BACKGROUND: Inadequate antenatal care (ANC) can lead to missed diagnosis of danger signs or delayed referral to emergency obstetrical care, contributing to maternal mortality. In developing countries, ANC quality is often limited by skill and knowledge gaps of the health workforce. In 2011, the Mentorship, Enhanced Supervision for Healthcare and Quality Improvement (MESH-QI) program was implemented to strengthen providers' ANC performance at 21 rural health centers in Rwanda. We evaluated the effect of MESH-QI on the completeness of danger sign assessments. METHODS: Completeness of danger sign assessments was measured by expert nurse mentors using standardized observation checklists. Checklists completed from October 2010 to May 2011 (n = 330) were used as baseline measurement and checklists completed between February and November 2012 (12-15 months after the start of MESH-QI implementation) were used for follow-up. We used a mixed-effects linear regression model to assess the effect of the MESH-QI intervention on the danger sign assessment score, controlling for potential confounders and the clustering of effect at the health center level. RESULTS: Complete assessment of all danger signs improved from 2.1% at baseline to 84.2% after MESH-QI (p < 0.001). Similar improvements were found for 20 of 23 other essential ANC screening items. After controlling for potential confounders, the improvement in danger sign assessment score was significant. However, the effect of the MESH-QI was different by intervention district and type of observed ANC visit. In Southern Kayonza District, the increase in the danger sign assessment score was 6.28 (95% CI: 5.59, 6.98) for non-first ANC visits and 5.39 (95% CI: 4.62, 6.15) for first ANC visits. In Kirehe District, the increase in danger sign assessment score was 4.20 (95% CI: 3.59, 4.80) for non-first ANC visits and 3.30 (95% CI: 2.80, 3.81) for first ANC visits. CONCLUSION: Assessment of critical danger signs improved under MESH-QI, even when controlling for nurse-mentees' education level and previous training in focused ANC. MESH-QI offers an approach to enhance quality of care after traditional training and may be an approach to support newer providers who have not yet attended content-focused courses. PMID- 29471831 TI - Prediction of suboptimal cytoreductive surgery in patients with advanced ovarian cancer based on preoperative and intraoperative determination of the peritoneal carcinomatosis index. AB - BACKGROUND: The peritoneal carcinomatosis index (PCI) can be used to quantify the tumor burden in patients with advanced ovarian cancer. The aim of the present study was to establish a predictive model for suboptimal cytoreductive surgery (SCS) (residual tumor of > 1 cm) using preoperative and intraoperative determination of the PCI. METHODS: In total, 110 consecutive patients treated for advanced ovarian cancer during a 4-year period in our institution were assessed. Eighty of these patients were eligible for primary debulking surgery and thus included in the present study. All data were prospectively collected and retrospectively evaluated. We determined the PCI both preoperatively and intraoperatively and assessed postoperative complications. RESULTS: A PCI of > 20 was the best cut-off with which to predict a risk of SCS among all three diagnostic techniques assessed in this study (computed tomography, laparoscopy, and laparotomy). Intraoperative PCI determination was associated with the lowest risk of false negatives for SCS when detecting a PCI of < 20. The combination of preoperative computed tomography and laparoscopy, when both techniques predicted SCS, was associated with the lowest risk of false positives for SCS when detecting a PCI of > 20. CONCLUSION: The combination of computed tomography and laparoscopy to obtain the PCI can help to determine which patients with advanced ovarian cancer are suitable for primary debulking surgery and which should undergo neoadjuvant chemotherapy. PMID- 29471832 TI - Accuracy and impact of spatial aids based upon satellite enumeration to improve indoor residual spraying spatial coverage. AB - BACKGROUND: Indoor residual spraying (IRS) is a key tool in the fight to control, eliminate and ultimately eradicate malaria. IRS protection is based on a communal effect such that an individual's protection primarily relies on the community level coverage of IRS with limited protection being provided by household-level coverage. To ensure a communal effect is achieved through IRS, achieving high and uniform community-level coverage should be the ultimate priority of an IRS campaign. Ensuring high community-level coverage of IRS in malaria-endemic areas is challenging given the lack of information available about both the location and number of households needing IRS in any given area. A process termed 'mSpray' has been developed and implemented and involves use of satellite imagery for enumeration for planning IRS and a mobile application to guide IRS implementation. This study assessed (1) the accuracy of the satellite enumeration and (2) how various degrees of spatial aid provided through the mSpray process affected community-level IRS coverage during the 2015 spray campaign in Zambia. METHODS: A 2-stage sampling process was applied to assess accuracy of satellite enumeration to determine number and location of sprayable structures. Results indicated an overall sensitivity of 94% for satellite enumeration compared to finding structures on the ground. RESULTS: After adjusting for structure size, roof, and wall type, households in Nchelenge District where all types of satellite-based spatial aids (paper-based maps plus use of the mobile mSpray application) were used were more likely to have received IRS than Kasama district where maps used were not based on satellite enumeration. The probability of a household being sprayed in Nchelenge district where tablet-based maps were used, did not differ statistically from that of a household in Samfya District, where detailed paper-based spatial aids based on satellite enumeration were provided. CONCLUSION: IRS coverage from the 2015 spray season benefited from the use of spatial aids based upon satellite enumeration. These spatial aids can guide costly IRS planning and implementation leading to attainment of higher spatial coverage, and likely improve disease impact. PMID- 29471833 TI - Plasmodium falciparum diagnostic tools in HIV-positive under-5-year-olds in two ART clinics in Ghana: are there missed infections? AB - BACKGROUND: Plasmodium falciparum, the most dominant species in sub-Saharan Africa, causes the most severe clinical malaria manifestations. In resource limited Ghana, where malaria and HIV geographically overlap, histidine-rich protein 2 (HRP2)-based rapid diagnostic test (RDT) is a faster, easier and cheaper alternative to clinical gold standard light microscopy. However, mutations in parasite hrp2 gene may result in missed infections, which have severe implications for malaria control. METHODS: The performance of a common HRP2-based RDT and expert light microscopy in HIV-positive and HIV-negative children under 5 years old was compared with PCR as laboratory gold standard. Finger-prick capillary blood was tested with First Response(r) Malaria Ag P. falciparum (HRP2). Giemsa-stained thick and thin blood films were examined with >= 200 high power fields and parasites counted per 200 white blood cells. Nested PCR species identification of P. falciparum was performed and resolved on agarose gel. False negatives from RDT were further tested for deleted pfhrp2/3 and flanking genes, using PCR. The study was performed in two anti-retroviral therapy clinics in Accra and Atibie. RESULTS: Out of 401 participants enrolled, 150 were HIV positive and 251 HIV negative. Malaria was more prevalent in children without HIV. Microscopy had a higher sensitivity [100% (99-100)] than RDT [83% (53.5 100)]. Parasites with pfhrp2/3 deletions contributed to missed infections from RDT false negatives. CONCLUSION: Circulation of malaria parasites with pfrhp2/3 deletions in this population played a role in missed infections with RDT. This ought to be addressed if further strides in malaria control are to be made. PMID- 29471834 TI - Widening disparities in health between educational levels and their determinants in later life: evidence from a nine-year cohort study. AB - BACKGROUND: Education has attracted more attention as a key determinant of health in later life. In this study, the hypothesis that widened educational disparities in health can be observed in later life was investigated, and the factors that mediated the association between education and changes in health were also assessed. METHODS: Using the 9-year (10-wave) longitudinal data of 20,024 individuals (9320 men and 10,704 women) aged 50-59 years at baseline, collected from a nationwide population survey in Japan (2005-2014), the changes in self rated health, functional limitations, and psychological distress between educational levels were compared. Mediation analysis was further conducted to assess the factors that mediated the association between education and changes in health, with reference to six types of potential mediators (household spending, social participation, leisure-time physical activity, smoking, problem drinking, and regular health check-ups). The analyses were conducted separately for men and women. RESULTS: All three health variables rapidly deteriorated among lower educated men and women. For men, the six potential mediators mediated 55.2%, 64.3%, and 47.3% of the associations between educational levels and changes in self-rated health, functional limitations, and psychological distress, respectively. The proportions for women were 42.0%, 49.5%, and 58.8%, respectively. Social participation was the primary mediator, followed by physical activity, regular health check-ups, and smoking. In general, no substantial or consistent differences were observed between men and women. CONCLUSIONS: The results suggested that policy measures that encourage social participation and promote healthy behaviors can improve educational disparities in health in later life. PMID- 29471835 TI - Dietary quality linkage to overall competence at school and emotional disturbance in representative Taiwanese young adolescents: dependence on gender, parental characteristics and personal behaviors. AB - BACKGROUND: Child school performance during puberty may be at increased risk through emotional disturbance. It is hypothesized that this may be mitigated by dietary quality. METHODS: In a nationally representative sample (Nutrition and Health Survey in Taiwan, NAHSIT), 1371 Taiwanese aged 11-16 years, overall competence at school, (OCS) and emotional status have been assessed by teachers with the SAED (Scale for Assessing Emotional Disturbance). Parents provided family socio-demographics and students completed a behavioral and dietary questionnaire (Youth Healthy Eating Index - Taiwan, YHEI-TW). Associations between emotional disturbance (ED), OCS and dietary quality (YHEI-TW) were assessed in multiple linear regression models with adjustments for covariates including parental characteristics, personal behaviors, body fatness and puberty. RESULTS: Boys or girls with ED had a less favorable OCS (p < 0.001), minimally dependent on YHEI-TW. On multivariable analysis there was a more positive association between OCS and YHEI-TW among boys (beta = 0.05, p < 0.01) and girls (beta = 0.07, p < 0.001). Poor dietary quality was associated with ED, especially in girls (beta = - 0.06, p < 0.001). Additionally, parental characteristics, body fatness, and personal behaviors are associated with OCS. Puberty is associated with ED and may be indirectly linked to OCS. CONCLUSIONS: Unsatisfactory food intake is associated with the link between emotional disturbance and impaired school performance, as assessed by OCS, especially among girls. For both genders, socio-economic and behavioral factors including parenteral income, reading, screen viewing and smoking are modulators of this association. Puberty was a modifying factor in girls. Dietary quality is a relevant factor for health (ED) as well as education (OCS) during early adolescence. PMID- 29471837 TI - The effect of knowledge on uptake of breast cancer prevention modalities among women in Kyadondo County, Uganda. AB - BACKGROUND: Breast cancer, the third most frequent cancer of women is preventable through knowledge on breast self-examination. Of the 44% of women diagnosed with breast cancer at the Uganda Cancer Institute, only 22% go for check-up in less than three months. This study explored the effect of breast cancer knowledge on the uptake of breast cancer prevention modalities among women in Kyadondo County, Uganda. METHODS: A household survey of women in Kyadondo County was conducted during June, 2014 to August, 2015. This involved studying in-depth using a questionnaire the level of breast cancer knowledge of the respondents. Data was analyzed using logistic regression model. Chi-square test was used to establish relationships between knowledge base factors and the uptake of breast cancer prevention modalities. RESULTS: This study has established an empirical relationship between uptake of breast cancer prevention modalities and source of information especially radio (OR 1.94 95% CI: 1.16-3.24), television (OR 1.82 95%CI: 1.14-2.93), awareness of breast cancer (OR 4.03 95%CI: 1.01-15.98), knowledge on how to reduce risk of breast cancer (OR 1.98 95% CI: 1.20-3.27), what reduces breast cancer acquisition (OR 2.75 95% CI: 1.42-5.35), how to check for signs of breast cancer especially through breast self-examination (OR 3.09 95% CI: 1.62-5.88), and other methods of breast cancer diagnosis in a health care set up. CONCLUSION: The women's level of breast cancer awareness as a primary prevention strategy was found wanting, and requires a boost through community health education. PMID- 29471836 TI - Differences in health literacy profiles of patients admitted to a public and a private hospital in Melbourne, Australia. AB - BACKGROUND: Health literacy refers to an individual's ability to find, understand and use health information in order to promote and maintain health. An individual's health literacy may also be influenced by the way health care organisations deliver care. The aim of this study was to investigate the influence of hospital service type (public versus private) on individual health literacy. METHODS: Two cross-sectional surveys were conducted using the Health Literacy Questionnaire (HLQ), a multi-dimensional self-report instrument covering nine health literacy domains. Recently discharged private patients (n = 3121) were sent the survey in English, public patients (n = 384) were sent the survey in English, Arabic, Chinese, Vietnamese, Italian or Greek. Eligibility included hospitalisation >=24 h in last 30 days, aged >=18 years, no cognitive impairment. Odds ratios were used to assess differences between hospital sociodemographic and health related variables. ANOVA and Cohen's effect sizes compared HLQ scores between hospitals. Chi square and multiple logistic regression were used to determine whether differences between private and public hospital HLQ scores was independent of hospital population sociodemographic differences. ANOVA was used to review associations between HLQ scores and subgroups of demographic, health behaviour and health conditions and these were then compared across the two hospital populations. RESULTS: Public hospital participants scored lower than private hospital participants on eight of the nine health literacy domains of the HLQ (scores for Active Appraisal did not differ between the two samples). Six domains, five of which in part measure the impact of how care is delivered on health literacy, remained lower among public hospital participants after controlling for age, education, language and income. Across both hospital populations, participants who were smokers, those who had low physical activity, those with depression and/or anxiety and those with 3 or more chronic conditions reported lower scores on some HLQ domains. CONCLUSIONS: Our finding of lower health literacy among patients who had received care at a public hospital in comparison to a private hospital, even after adjustment for sociodemographic and language differences, suggests that private hospitals may possess organisational attributes (environment, structure, values, practices and/or workforce competencies) that result in improved health literacy responsiveness. PMID- 29471838 TI - Impact assessment of Iran's health technology assessment programme. AB - BACKGROUND: Following approximately 10 years from the beginning of Iran's national Health Technology Assessment (HTA) programme, the present study aims to evaluate its success by examining the impact of HTA and identifying the determinant factors leading to the implementation of HTA report results. METHODS: The triangulation method was employed herein. HTA reports were initially identified and their impact and determinant factors were then examined from the perspectives of both researchers (by preparing a questionnaire according to the Payback model and sending it to HTA principle investigators) and stakeholders (semi-structured interviews held with each HTA stakeholder). Simultaneously, the quality of the HTA reports was examined with relevant critical appraisal checklists. RESULTS: The impact of 19 equipment technologies and four pharmaceutical technologies were assessed in this study. Twenty researchers replied (response rate, 86.96%) to the questionnaire on the impact of HTA reports from the researcher's perspective. To assess the impact of HTA reports from the stakeholder's perspective, seven policy-makers were chosen and interviewed as the main target audience. The most common step taken to disseminate the results of the HTA projects was publication. Conducting the HTA had taught researchers and their colleagues' new skills and had facilitated the securing of research grants from other organisations. Most reports had used the systematic review method but the relevant details had been scarcely presented regarding outcomes, costs and analysis. The greatest impact of HTA reports on decision-making had been on policy-makers providing and allocating finances. Barriers in stewardship, identification and prioritisation of topics, performance and dissemination of HTA results were the main barriers of implementing HTAs. CONCLUSIONS: In most aspects, the status of HTA impact reports need improvement. Thus far, the barriers and facilitators of the HTA programme in Iran have been investigated in other studies. These findings should be pooled to reach a solution that can be actively applied to the health system to improve the status quo of HTA in Iran. PMID- 29471840 TI - Designing evaluation studies to optimally inform policy: what factors do policy makers in China consider when making resource allocation decisions on healthcare worker training programmes? AB - BACKGROUND: In light of the gap in evidence to inform future resource allocation decisions about healthcare provider (HCP) training in low- and middle-income countries (LMICs), and the considerable donor investments being made towards training interventions, evaluation studies that are optimally designed to inform local policy-makers are needed. The aim of our study is to understand what features of HCP training evaluation studies are important for decision-making by policy-makers in LMICs. We investigate the extent to which evaluations based on the widely used Kirkpatrick model - focusing on direct outcomes of training, namely reaction of trainees, learning, behaviour change and improvements in programmatic health indicators - align with policy-makers' evidence needs for resource allocation decisions. We use China as a case study where resource allocation decisions about potential scale-up (using domestic funding) are being made about an externally funded pilot HCP training programme. METHODS: Qualitative data were collected from high-level officials involved in resource allocation at the national and provincial level in China through ten face-to face, in-depth interviews and two focus group discussions consisting of ten participants each. Data were analysed manually using an interpretive thematic analysis approach. RESULTS: Our study indicates that Chinese officials not only consider information about the direct outcomes of a training programme, as captured in the Kirkpatrick model, but also need information on the resources required to implement the training, the wider or indirect impacts of training, and the sustainability and scalability to other settings within the country. In addition to considering findings presented in evaluation studies, we found that Chinese policy-makers pay close attention to whether the evaluations were robust and to the composition of the evaluation team. CONCLUSIONS: Our qualitative study indicates that training programme evaluations that focus narrowly on direct training outcomes may not provide sufficient information for policy-makers to make decisions on future training programmes. Based on our findings, we have developed an evidence-based framework, which incorporates but expands beyond the Kirkpatrick model, to provide conceptual and practical guidance that aids in the design of training programme evaluations better suited to meet the information needs of policy-makers and to inform policy decisions. PMID- 29471839 TI - Controlled Education of patients after Stroke (CEOPS)- nurse-led multimodal and long-term interventional program involving a patient's caregiver to optimize secondary prevention of stroke: study protocol for a randomized controlled trial. AB - BACKGROUND: Setting up a follow-up secondary prevention program after stroke is difficult due to motor and cognitive impairment, but necessary to prevent recurrence and improve patients' quality of life. To involve a referent nurse and a caregiver from the patient's social circle in nurse-led multimodal and long term management of risk factors after stroke could be an advantage due to their easier access to the patient and family. The aim of this study is to compare the benefit of optimized follow up by nursing personnel from the vascular neurology department including therapeutic follow up, and an interventional program directed to the patient and a caregiving member of their social circle, as compared with typical follow up in order to develop a specific follow-up program of secondary prevention of stroke. METHODS/DESIGN: The design is a randomized, controlled, clinical trial conducted in the French Stroke Unit of the Strokavenir network. In total, 410 patients will be recruited and randomized in optimized follow up or usual follow up for 2 years. In both group, patients will be seen by a neurologist at 6, 12 and 24 months. The optimized follow up will include follow up by a nurse from the vascular neurology department, including therapeutic follow up, and a training program on secondary prevention directed to the patient and a caregiving member of their social circle. After discharge, a monthly telephone interview, in the first year and every 3 months in the second year, will be performed by the nurse. At 6, 12 and 24 month, the nurse will give the patient and caregiver another training session. Usual follow up is only done by the patient's general practitioner, after classical information on secondary prevention of risk factors during hospitalization. The primary outcome measure is blood pressure measured after the first year of follow up. Blood pressure will be measured by nursing personnel who do not know the group into which the patient has been randomized. Secondary endpoints are associated mortality, morbidity, recurrence, drug side-effects and medico-economic analysis. DISCUSSION: The result of this trial is expected to provide the benefit of a nurse-led optimized multimodal and long-term interventional program for management of risk factors after stroke, personalizing the role of the nurse and including the patient's caregiver.

PMID- 29471842 TI - Toxoplasma gondii alters NMDAR signaling and induces signs of Alzheimer's disease in wild-type, C57BL/6 mice. AB - BACKGROUND: Alzheimer's disease (AD) is a progressive neurodegenerative disease associated with cognitive decline and complete loss of basic functions. The ubiquitous apicomplexan parasite Toxoplasma gondii (T. gondii) infects up to one third of the world's population and is implicated in AD. METHODS: We infected C57BL/6 wild-type male and female mice with 10 T. gondii ME49 cysts and assessed whether infection led to behavioral and anatomical effects using immunohistochemistry, immunofluorescence, Western blotting, cell culture assays, as well as an array of mouse behavior tests. RESULTS: We show that T. gondii infection induced two major hallmarks of AD in the brains of C57BL/6 male and female mice: beta-amyloid (Abeta) immunoreactivity and hyperphosphorylated Tau. Infected mice showed significant neuronal death, loss of N-methyl-D-aspartate receptor (NMDAR) expression, and loss of olfactory sensory neurons. T. gondii infection also caused anxiety-like behavior, altered recognition of social novelty, altered spatial memory, and reduced olfactory sensitivity. This last finding was exclusive to male mice, as infected females showed intact olfactory sensitivity. CONCLUSIONS: These results demonstrate that T. gondii can induce advanced signs of AD in wild-type mice and that it may induce AD in some individuals with underlying health problems. PMID- 29471843 TI - Prevalence and phylogenetic analysis of hepatitis E virus in pigs, wild boars, roe deer, red deer and moose in Lithuania. AB - BACKGROUND: Hepatitis E virus (HEV) is one of the major causes of acute viral hepatitis worldwide. In Europe, food-borne zoonotic transmission of HEV genotype 3 has been associated with domestic pigs and wild boar. Controversial data are available on the circulation of the virus in animals that are used for human consumption, and to date, no gold standard has yet been defined for the diagnosis of HEV-associated hepatitis. To investigate the current HEV infection status in Lithuanian pigs and wild ungulates, the presence of viral RNA was analyzed by nested reverse transcription polymerase chain reaction (RT-nPCR) in randomly selected samples, and the viral RNA was subsequently genotyped. RESULTS: In total, 32.98 and 22.55% of the domestic pig samples were HEV-positive using RT nPCR targeting the ORF1 and ORF2 fragments, respectively. Among ungulates, 25.94% of the wild boar samples, 22.58% of the roe deer samples, 6.67% of the red deer samples and 7.69% of the moose samples were positive for HEV RNA using primers targeting the ORF1 fragment. Using primers targeting the ORF2 fragment of the HEV genome, viral RNA was only detected in 17.03% of the wild boar samples and 12.90% of the roe deer samples. Phylogenetic analysis based on a 348-nucleotide-long region of the HEV ORF2 showed that all obtained sequences detected in Lithuanian domestic pigs and wildlife belonged to genotype 3. In this study, the sequences identified from pigs, wild boars and roe deer clustered within the 3i subtype reference sequences from the GenBank database. The sequences obtained from pig farms located in two different counties of Lithuania were of the HEV 3f subtype. The wild boar sequences clustered within subtypes 3i and 3h, clearly indicating that wild boars can harbor additional subtypes of HEV. For the first time, the ORF2 nucleotide sequences obtained from roe deer proved that HEV subtype 3i can be found in a novel host. CONCLUSION: The results of the viral prevalence and phylogenetic analyses clearly demonstrated viral infection in Lithuanian pigs and wild ungulates, thus highlighting a significant concern for zoonotic virus transmission through both the food chain and direct contact with animals. Unexpected HEV genotype 3 subtype diversity in Lithuania and neighboring countries revealed that further studies are necessary to understand the mode of HEV transmission between animals and humans in the Baltic States region. PMID- 29471844 TI - Spatiotemporal patterns and environmental drivers of human echinococcoses over a twenty-year period in Ningxia Hui Autonomous Region, China. AB - BACKGROUND: Human cystic (CE) and alveolar (AE) echinococcoses are zoonotic parasitic diseases that can be influenced by environmental variability and change through effects on the parasites, animal intermediate and definitive hosts, and human populations. We aimed to assess and quantify the spatiotemporal patterns of human echinococcoses in Ningxia Hui Autonomous Region (NHAR), China between January 1994 and December 2013, and examine associations between these infections and indicators of environmental variability and change, including large-scale landscape regeneration undertaken by the Chinese authorities. METHODS: Data on the number of human echinococcosis cases were obtained from a hospital-based retrospective survey conducted in NHAR for the period 1 January 1994 through 31 December 2013. High-resolution imagery from Landsat 4/5-TM and 8-OLI was used to create single date land cover maps. Meteorological data were also collected for the period January 1980 to December 2013 to derive time series of bioclimatic variables. A Bayesian spatio-temporal conditional autoregressive model was used to quantify the relationship between annual cases of CE and AE and environmental variables. RESULTS: Annual CE incidence demonstrated a negative temporal trend and was positively associated with winter mean temperature at a 10-year lag. There was also a significant, nonlinear effect of annual mean temperature at 13 year lag. The findings also revealed a negative association between AE incidence with temporal moving averages of bareland/artificial surface coverage and annual mean temperature calculated for the period 11-15 years before diagnosis and winter mean temperature for the period 0-4 years. Unlike CE risk, the selected environmental covariates accounted for some of the spatial variation in the risk of AE. CONCLUSIONS: The present study contributes towards efforts to understand the role of environmental factors in determining the spatial heterogeneity of human echinococcoses. The identification of areas with high incidence of CE and AE may assist in the development and refinement of interventions for these diseases, and enhanced environmental change risk assessment. PMID- 29471845 TI - Association of the client-provider ratio with the risk of maternal mortality in referral hospitals: a multi-site study in Nigeria. AB - BACKGROUND: The paucity of human resources for health buoyed by excessive workloads has been identified as being responsible for poor quality obstetric care, which leads to high maternal mortality in Nigeria. While there is anecdotal and qualitative research to support this observation, limited quantitative studies have been conducted to test the association between the number and density of human resources and risk of maternal mortality. This study aims to investigate the association between client-provider ratios for antenatal and delivery care and the risk of maternal mortality in 8 referral hospitals in Nigeria. METHODS: Client-provider ratios were calculated for antenatal and delivery care attendees during a 3-year period (2011-2013). The maternal mortality ratio (MMR) was calculated per 100,000 live births for the hospitals, while unadjusted Poisson regression analysis was used to examine the association between the number of maternal deaths and density of healthcare providers. RESULTS: A total of 334,425 antenatal care attendees and 26,479 births were recorded during this period. The client-provider ratio in the maternity department for antenatal care attendees was 1343:1 for doctors and 222:1 for midwives. The ratio of births to one doctor in the maternity department was 106:1 and 18:1 for midwives. On average, there were 441 births per specialist obstetrician. The results of the regression analysis showed a significant negative association between the number of maternal deaths and client-provider ratios in all categories. CONCLUSION: We conclude that the maternal mortality ratios in Nigeria's referral hospitals are worsened by high client-provider ratios, with few providers attending a large number of pregnant women. Efforts to improve the density and quality of maternal healthcare providers, especially at the first referral level, would be a critical intervention for reducing the currently high rate of maternal mortality in Nigeria.

PMID- 29471846 TI - Understanding nurses' dual practice: a scoping review of what we know and what we still need to ask on nurses holding multiple jobs. AB - BACKGROUND: Mounting evidence suggests that holding multiple concurrent jobs in public and private (dual practice) is common among health workers in low- as well as high-income countries. Nurses are world's largest health professional workforce and a critical resource for achieving Universal Health Coverage. Nonetheless, little is known about nurses' engagement with dual practice. METHODS: We conducted a scoping review of the literature on nurses' dual practice with the objective of generating hypotheses on its nature and consequences, and define a research agenda on the phenomenon. The Arksey and O'Malley's methodological steps were followed to develop the research questions, identify relevant studies, include/exclude studies, extract the data, and report the findings. PRISMA guidelines were additionally used to conduct the review and report on results. RESULTS: Of the initial 194 records identified, a total of 35 met the inclusion criteria for nurses' dual practice; the vast majority (65%) were peer-reviewed publications, followed by nursing magazine publications (19%), reports, and doctoral dissertations. Twenty publications focused on high-income countries, 16 on low- or middle-income ones, and two had a multi country perspective. Although holding multiple jobs not always amounted to dual practice, several ways were found for public-sector nurses to engage concomitantly in public and private employments, in regulated as well as in informal, casual fashions. Some of these forms were reported as particularly prevalent, from over 50% in Australia, Canada, and the UK, to 28% in South Africa. The opportunity to increase a meagre salary, but also a dissatisfaction with the main job and the flexibility offered by multiple job-holding arrangements, were among the reported reasons for engaging in these practices. DISCUSSION AND CONCLUSIONS: Limited and mostly circumstantial evidence exists on nurses' dual practice, with the few existing studies suggesting that the phenomenon is likely to be very common and carry implications for health systems and nurses' welfare worldwide. We offer an agenda for future research to consolidate the existing evidence and to further explore nurses' motivation; without a better understanding of nurse dual practice, this will continue to be a largely 'hidden' element in nursing workforce policy and practice, with an unclear impact on the delivery of care. PMID- 29471847 TI - The impact of metallothionein-II on microglial response to tumor necrosis factor alpha (TNFalpha) and downstream effects on neuronal regeneration. AB - BACKGROUND: The extracellular environment plays an important role in supporting the regeneration of axons after injury. Metallothionein-II (MTII) is a metal binding protein known for its neuroprotective effect by directly stimulating the growth of axons after injury. Previous studies have shown that MTII also modulates the response of astrocytes and microglia after injury. However, a detailed analysis describing how MTII modulates the interaction between microglia and neurons is lacking. METHODS: We introduced fluorescently labelled MTII into the cortex at the time of needlestick injury to investigate the cellular uptake of MTII using immunohistochemistry with antibodies against cell-type-specific markers. The role of MTII in modulating the effect of microglia on axon outgrowth following an inflammatory response is further investigated using a co-culture model involving primary rodent microglia pre-treated with TNFalpha and primary rodent cortical neurons. The axon lengths were assessed 24 h after the plating of the neurons onto treated microglia. We also utilised siRNA to knockdown the expression of LRP1, which allows us to investigate the role of LRP1 receptors in the MTII-mediated effect of microglia on axon outgrowth. RESULTS: Fluorescently labelled MTII was found to be associated with neurons, astrocytes and microglia following injury in vivo. Microglia-neuron co-culture experiments demonstrated that exogenous MTII altered the response of microglia to TNFalpha. The neurons plated onto the TNFalpha-stimulated microglia pre-treated with MTII have shown a significantly longer axonal length compare to the TNFalpha-stimulated microglia without the MTII treatment. This suggested that MTII reduce cytokine-stimulated activation of microglia, which would ordinarily impair neurite outgrowth. This inhibitory effect of MTII on activated microglia was blocked by siRNA-mediated downregulation of LRP1 receptor expression in microglia, suggesting that MTII acts via the LRP1 receptor on microglia. CONCLUSIONS: This study demonstrates that exogenous MTII acts via the LRP1 receptor to alter the inflammatory response of microglia following TNFalpha stimulation, providing a more supportive environment for axon growth. PMID- 29471848 TI - Canine caliciviruses of four serotypes from military and research dogs recovered in 1963-1978 belong to two phylogenetic clades in the Vesivirus genus. AB - BACKGROUND: Vesiviruses (family Caliciviridae) had been shown capable of invading a variety of host species, raising concern of their zoonotic potential. Since the 1980's, several canine caliciviruses (CaCV) isolates have been reported and are phylogenetically related to the vesiviruses with features distinct from both Vesicular exanthema of swine virus (VESV) and Feline calicivirus (FCV) species in phylogeny, serology and cell culture specificities. Etiological studies of canine diseases in dogs used for military services and laboratory studies were conducted in 1963-1978 at the Walter Reed Army Institute of Research. Multiple known and unknown viral pathogens including caliciviruses were recovered. METHODS: Four unidentified isolates were recovered in Walter Reed Canine Cells (WRCC) from respiratory, fecal and penile specimens. Physicochemical tests, electron microscopy, viral cultivation in human and animal cells, antibody neutralization assays, and recently the genome sequencing were used to characterize the isolates. Sera from these dogs and their cohorts were tested with the isolates to determine origin and prevalence of the infections. RESULTS: The viral isolates were small non-enveloped spherical RNA virions, 27 to 42 nm in diameter with cup like structures, indicating they are caliciviruses. They propagated in WRCC and MDCK cells, not in either other canine cells or human and other animal cells. Each isolate is antigenically distinct and react with dog sera in respective cohorts. The genomes have nucleotide identities ranging from 70.3% to 90.7% and encode the non-structural polyprotein (1810 amino acids), major capsid protein (691 amino acids) and minor structural protein (134 amino acids). They belong to two different phylogenetic clades in Vesivirus genus with close relation with canine calicivirus (CaCV). CONCLUSIONS: These CaCV isolates have restricted cell tropism, antigenic diversity and genetic variation. Further investigation will shed light on antigenic relation to other vesiviruses, and its pathogenicity for dogs and potential infectivity to other animals. Together with the previously reported CaCV strains provides significant evidence to support the formation of a new CaCV species in the Vesivirus genus. PMID- 29471849 TI - Implementing Alcohol Misuse SBIRT in a National Cohort of Pediatric Trauma Centers-a type III hybrid effectiveness-implementation trial. AB - BACKGROUND: The American College of Surgeons mandates universal screening for alcohol misuse and delivery of an intervention for those screening positive as a requirement for certification as a level 1 trauma center. Though this requirement has been mandated for over a decade, its implementation has been challenging. Our research team completed an implementation study supporting seven pediatric trauma centers' compliance with the requirement by developing and implementing an institutional alcohol Screening, Brief Intervention and Referral to Treatment (SBIRT) policy for adolescent trauma patients. A mixed-methods approach indicated that SBIRT adoption rates increased at all sites; however, providers' fidelity to the SBIRT intervention was variable, and providers reported a number of barriers to SBIRT implementation. The goal of this study is to conduct a fully powered type III hybrid effectiveness-implementation trial to test the effectiveness of a comprehensive implementation strategy in increasing the implementation of SBIRT for alcohol and other drug use (AOD) in pediatric trauma centers. METHODS: Our implementation strategy is based on the Science to Service Laboratory (SSL), an approach developed by the SAMHSA-funded Addiction Technology Transfer Centers that consists of three core elements (i.e., didactic training + performance feedback + leadership coaching). Utilizing a stepped wedge design, a national cohort of 10 pediatric trauma centers will receive the SSL implementation strategy. At six distinct time points, each of the 10 sites will provide data from 30 electronic medical records (n = 1800 in total). A subset of adolescents will also report on fidelity of intervention delivery and linkage to care (i.e., continued AOD discussion and/or treatment with a primary care provider) 1 month after hospital discharge. In addition, nurses, social workers, and leaders will report on organizational readiness for implementation at four distinct time points. DISCUSSION: This protocol proposes a unique opportunity to examine whether a comprehensive implementation strategy can improve the fidelity of SBIRT delivery across a national cohort of pediatric trauma centers. With injured adolescents, this could optimize the detection and intervention of AOD use and improve adolescent health. TRIAL REGISTRATION: Clinicaltrials.gov NCT03297060 . PMID- 29471850 TI - Taliglucerase alfa: safety and efficacy across 6 clinical studies in adults and children with Gaucher disease. AB - Taliglucerase alfa is an enzyme replacement therapy (ERT) approved for treatment of adult and paediatric patients with Type 1 Gaucher disease (GD) in several countries and the first plant cell-expressed recombinant therapeutic protein approved by the US Food and Drug Administration for humans. Here, we review the findings across six key taliglucerase alfa clinical studies. A total of 33 treatment-naive adult patients were randomized to taliglucerase alfa 30 U/kg or 60 U/kg in a 9-month, multicentre, randomized, double-blind, parallel-group, dose comparison pivotal study, after which eligible patients continued into two consecutive extension studies; 17 treatment-naive adult patients completed 5 total years of treatment with taliglucerase alfa. In the only ERT study focused on exclusively paediatric patients with GD, 11 treatment-naive children were randomized to taliglucerase alfa 30 U/kg or 60 U/kg in a 12-month, multicentre, double-blind study; nine completed 3 total years of treatment in a dedicated paediatric extension study. The effect of switching patients from imiglucerase to taliglucerase alfa was also investigated in a separate 9-month study that included 26 adults and five children; 10 adults completed a total of 3 years and two children completed a total of 2.75 years of taliglucerase alfa treatment in the extension studies. All studies evaluated safety and spleen volume, liver volume, platelet count, haemoglobin concentration, and biomarkers as measures of efficacy. Detailed results from baseline through the end of these studies are presented. Taliglucerase alfa was well tolerated, and adverse events were generally mild/moderate in severity and transient. Treatment with taliglucerase alfa resulted in improvements (treatment-naive patients) or stability (patients switched from imiglucerase) in visceral, haematologic, and biomarker parameters. Together, this comprehensive data set supports the treatment of adult and paediatric patients with GD who are naive to ERT or who have previously been treated with imiglucerase. PMID- 29471851 TI - Multilocus sequence typing: genetic diversity in Trypanosoma cruzi I (TcI) isolates from Brazilian didelphids. AB - BACKGROUND: Trypanosoma cruzi is a protozoan parasite characterized by extensive genetic heterogeneity. There are currently six recognised, genetically distinct, monophyletic clades designated discrete typing units (DTUs). TcI has the broadest geographical range and most genetic diversity evidenced by a wide range of genetic markers applied to isolates spanning a vast geographical range across Latin America. However, little is known of the diversity of TcI that exists within sylvatic mammals across the geographical expanse of Brazil. RESULTS: Twenty-nine sylvatic TcI isolates spanning multiple ecologically diverse biomes across Brazil were analyzed by the application of multilocus sequence typing (MLST) using four nuclear housekeeping genes. Results revealed extensive genetic diversity and also incongruence among individual gene trees. There was no association of intralineage genotype with geography or with any particular biome, with the exception of isolates from Caatinga that formed a single cluster. However, haplotypic analyses of METIII and LYT1 constitutive markers provided evidence of recombination events in two isolates derived from Didelphis marsupialis and D. albiventris, respectively. For diversity studies all possible combinations of markers were assessed with the objective of selecting the combination of gene targets that are most resolutive using the minimum number of genes. A panel of just three gene fragments (DHFR-TS, LYT1 and METIII) discriminated 26 out of 35 genotypes. CONCLUSIONS: These findings showed geographical association of genotypes clustering in Caatinga but more characteristically TcI genotypes widely distributed without specific association to geographical areas or biomes. Importantly, we detected the signature of recombination events at the nuclear level evidenced by haplotypic analysis and incongruence. PMID- 29471852 TI - CDK9 inhibitors in acute myeloid leukemia. AB - Current treatment for acute myeloid leukemia (AML) is less than optimal, but increased understanding of disease pathobiology and genomics has led to clinical investigation of novel targeted therapies and rational combinations. Targeting the cyclin-dependent kinase 9 (CDK9) pathway, which is dysregulated in AML, is an attractive approach. Inhibition of CDK9 leads to downregulation of cell survival genes regulated by super enhancers such as MCL-1, MYC, and cyclin D1. As CDK9 inhibitors are nonselective, predictive biomarkers that may help identify patients most likely to respond to CDK9 inhibitors are now being utilized, with the goal of improving efficacy and safety. PMID- 29471853 TI - Oncoprotein HBXIP enhances HOXB13 acetylation and co-activates HOXB13 to confer tamoxifen resistance in breast cancer. AB - BACKGROUND: Resistance to tamoxifen (TAM) frequently occurs in the treatment of estrogen receptor positive (ER+) breast cancer. Accumulating evidences indicate that transcription factor HOXB13 is of great significance in TAM resistance. However, the regulation of HOXB13 in TAM-resistant breast cancer remains largely unexplored. Here, we were interested in the potential effect of HBXIP, an oncoprotein involved in the acceleration of cancer progression, on the modulation of HOXB13 in TAM resistance of breast cancer. METHODS: The Kaplan-Meier plotter cancer database and GEO dataset were used to analyze the association between HBXIP expression and relapse-free survival. The correlation of HBXIP and HOXB13 in ER+ breast cancer was assessed by human tissue microarray. Immunoblotting analysis, qRT-PCR assay, immunofluorescence staining, Co-IP assay, ChIP assay, luciferase reporter gene assay, cell viability assay, and colony formation assay were performed to explore the possible molecular mechanism by which HBXIP modulates HOXB13. Cell viability assay, xenograft assay, and immunohistochemistry staining analysis were utilized to evaluate the effect of the HBXIP/HOXB13 axis on the facilitation of TAM resistance in vitro and in vivo. RESULTS: The analysis of the Kaplan-Meier plotter and the GEO dataset showed that mono-TAM-treated breast cancer patients with higher HBXIP expression levels had shorter relapse free survivals than patients with lower HBXIP expression levels. Overexpression of HBXIP induced TAM resistance in ER+ breast cancer cells. The tissue microarray analysis revealed a positive association between the expression levels of HBXIP and HOXB13 in ER+ breast cancer patients. HBXIP elevated HOXB13 protein level in breast cancer cells. Mechanistically, HBXIP prevented chaperone-mediated autophagy (CMA)-dependent degradation of HOXB13 via enhancement of HOXB13 acetylation at the lysine 277 residue, causing the accumulation of HOXB13. Moreover, HBXIP was able to act as a co-activator of HOXB13 to stimulate interleukin (IL)-6 transcription in the promotion of TAM resistance. Interestingly, aspirin (ASA) suppressed the HBXIP/HOXB13 axis by decreasing HBXIP expression, overcoming TAM resistance in vitro and in vivo. CONCLUSIONS: Our study highlights that HBXIP enhances HOXB13 acetylation to prevent HOXB13 degradation and co-activates HOXB13 in the promotion of TAM resistance of breast cancer. Therapeutically, ASA can serve as a potential candidate for reversing TAM resistance by inhibiting HBXIP expression. PMID- 29471855 TI - Phase-based treatment versus immediate trauma-focused treatment in patients with childhood trauma-related posttraumatic stress disorder: study protocol for a randomized controlled trial. AB - BACKGROUND: The treatment of posttraumatic stress disorder (PTSD) related to a history of sexual and/or physical abuse in childhood is the subject of international debate, with some favouring a phase-based approach as their preferred treatment, while others argue for immediate trauma-focused treatment. A history of (chronic) traumatisation during childhood has been linked to the development of distinct symptoms that are often labelled as symptoms of complex PTSD. Many therapists associate the presence of symptoms of complex PTSD with a less favourable treatment prognosis. The purpose of this study is to determine whether a phase-based approach is more effective than stand-alone trauma-focused therapy in individuals with PTSD and possible symptoms of complex PTSD resulting from a history of repeated sexual and/or physical abuse in childhood. An additional aim is to investigate moderators, predictors of treatment (non) response and drop-out. METHOD: The sample consists of patients between 18 and 65 years old with a diagnosis of PTSD who report a history of repeated sexual and/or physical abuse in childhood (N = 122). Patients will be blindly allocated to either 16 sessions of eye movement desensitization and reprocessing (EMDR) therapy preceded by a stabilization phase (eight sessions of Skills Training in Affect and Interpersonal Regulation (STAIR)) or only 16 sessions of EMDR therapy. Assessments are carried out pre-treatment, after every eighth session, post treatment, and at 3 and 6 months follow up. The main parameter will be the severity of PTSD symptoms (PTSD Symptoms Scale-Self Report). Secondary outcome variables are the presence of a PTSD diagnosis (Clinician-Administered PTSD Scale for DSM-5), severity of complex PTSD symptoms (Structured Interview for Disorders of Extreme Stress-Revised and symptoms-specific questionnaires), changes in symptoms of general psychopathology (Brief Symptom Inventory), and quality of life (Euroqol-5D). Health care consumption and productivity loss in patients will also be indexed. DISCUSSION: The study results may help to inform the ongoing debate about whether a phase-based approach has added value over immediate trauma focused therapy in patients suffering from PTSD due to childhood abuse. Furthermore, the results will contribute to knowledge about the safety, efficacy, and cost-effectiveness of treatments in this target group. TRIAL REGISTRATION: Nederlands Trialregister, NTR5991 .

AB - Cryo-electron microscopy has undergone a revolution in recent years and it has contributed significantly to a number of different areas in biological research. In this manuscript, we will describe some of the recent advancements in cryo electron microscopy focussing on the advantages that this technique can bring rather than on the technology. We will then conclude discussing how the field of retrovirology has benefited from cryo-electron microscopy. PMID- 29471856 TI - Quantitative cardiovascular magnetic resonance perfusion imaging identifies reduced flow reserve in microvascular coronary artery disease. AB - BACKGROUND: Preliminary semi-quantitative cardiovascular magnetic resonance (CMR) perfusion studies have demonstrated reduced myocardial perfusion reserve (MPR) in patients with angina and risk factors for microvascular disease (MVD), however fully quantitative CMR has not been studied. The purpose of this study is to evaluate whether fully quantitative CMR identifies reduced MPR in this population, and to investigate the relationship between epicardial atherosclerosis, left ventricular hypertrophy (LVH), extracellular volume (ECV), and perfusion. METHODS: Forty-six patients with typical angina and risk factors for MVD (females, or males with diabetes or metabolic syndrome) who had no obstructive coronary artery disease by coronary angiography and 20 healthy control subjects underwent regadenoson stress CMR perfusion imaging using a dual sequence quantitative spiral pulse sequence to quantify MPR. Subjects also underwent T1 mapping to quantify ECV, and computed tomographic (CT) coronary calcium scoring to assess atherosclerosis burden. RESULTS: In patients with risk factors for MVD, both MPR (2.21 [1.95,2.69] vs. 2.93 [2.763.19], p < 0.001) and stress myocardial perfusion (2.65 +/- 0.62 ml/min/g, vs. 3.17 +/- 0.49 ml/min/g p < 0.002) were reduced as compared to controls. These differences remained after adjusting for age, left ventricular (LV) mass, body mass index (BMI), and gender. There were no differences in native T1 or ECV between subjects and controls. CONCLUSIONS: Stress myocardial perfusion and MPR as measured by fully quantitative CMR perfusion imaging are reduced in subjects with risk factors for MVD with no obstructive CAD as compared to healthy controls. Neither myocardial hypertrophy nor fibrosis accounts for these differences. PMID- 29471858 TI - Tumor-promoting properties of miR-8084 in breast cancer through enhancing proliferation, suppressing apoptosis and inducing epithelial-mesenchymal transition. AB - BACKGROUND: Breast cancer is one of the most frequent malignancies and the second leading cause of cancer-related mortality in women. MicroRNAs play a key role in breast cancer development and progression. microRNA(miR)-8084 has been observed an aberrant expression in breast cancer. However, the functions and regulatory axes of miR-8084, particularly in breast cancer, were not entirely clear. METHODS: miR-8084 expression in breast cancer were investigated in a GEO dataset by in silico analysis and in 42 paired tumor tissues by qPCR. The effects of deregulation of miR-8084 on breast cancer cell proliferation, migration and invasion in vitro and tumorigenicity in vivo were examined by colony-formation assay, wound healing assay, transwell assay and nude mouse subcutaneous tumor formation model. The target gene of miR-8084 were predicted by TargetScan and miRDB, and confirmed by luciferase reporter system. The roles of miR-8084 in the breast cancer cell proliferation, apoptosis and epithelial-mesenchymal transition (EMT) were investigated by MTS, FACS and associated-marker detection by western blot. RESULTS: miR-8084 is significantly up-regulated in both serum and malignant tissues from the source of breast cancer patients. miR-8084 promotes the proliferation of breast cancer cells by activating ERK1/2 and AKT. Meanwhile miR 8084 inhibits apoptosis by decreasing p53-BAX related pathway. miR-8084 also enhances migration and invasion by inducing EMT. Moreover, the tumor suppressor ING2 is a potential target of miR-8084, and miR-8084 regulatory axes contribute to pro-tumor effect, at least partially through regulating ING2. CONCLUSION: Our results strongly suggest that miR-8084 functions as an oncogene that promotes the development and progression of breast cancer, and miR-8084 is a potential new diagnostic marker and therapeutic target of breast cancer. PMID- 29471857 TI - Patterns of Midichloria infection in avian-borne African ticks and their trans Saharan migratory hosts. AB - BACKGROUND: Ticks are obligate haematophagous ectoparasites of vertebrates and frequently parasitize avian species that can carry them across continents during their long-distance migrations. Ticks may have detrimental effects on the health state of their avian hosts, which can be either directly caused by blood-draining or mediated by microbial pathogens transmitted during the blood meal. Indeed, ticks host complex microbial communities, including bacterial pathogens and symbionts. Midichloria bacteria (Rickettsiales) are widespread tick endosymbionts that can be transmitted to vertebrate hosts during the tick bite, inducing an antibody response. Their actual role as infectious/pathogenic agents is, however, unclear. METHODS: We screened for Midichloria DNA African ticks and blood samples collected from trans-Saharan migratory songbirds at their arrival in Europe during spring migration. RESULTS: Tick infestation rate was 5.7%, with most ticks belonging to the Hyalomma marginatum species complex. Over 90% of Hyalomma ticks harboured DNA of Midichloria bacteria belonging to the monophylum associated with ticks. Midichloria DNA was detected in 43% of blood samples of avian hosts. Tick infested adult birds were significantly more likely to test positive to the presence of Midichloria DNA than non-infested adults and second-year individuals, suggesting a long-term persistence of these bacteria within avian hosts. Tick parasitism was associated with a significantly delayed timing of spring migration of avian hosts but had no significant effects on body condition, whereas blood Midichloria DNA presence negatively affected fat deposits of tick-infested avian hosts. CONCLUSIONS: Our results show that ticks effectively transfer Midichloria bacteria to avian hosts, supporting the hypothesis that they are infectious to vertebrates. Bird infection likely enhances the horizontal spread of these bacteria across haematophagous ectoparasite populations. Moreover, we showed that Midichloria and tick parasitism have detrimental non-independent effects on avian host health during migration, highlighting the complexity of interactions involving ticks, their vertebrate hosts, and tick-borne bacteria. PMID- 29471859 TI - Impact of time-related factors on biologically accurate radiotherapy treatment planning. AB - BACKGROUND: The incomplete repair (IR) model expresses the cell repair effect from radiation-induced damage over time, which is given little consideration in actual treatment planning. By incorporating the IR model into the normal tissue complication probability (NTCP), the accuracy and safety of treatment plan evaluations concerning the effect of repair can be improved. This study aims to evaluate the impact of incorporating the IR model into the NTCP by varying time related factors such as the repair half-time (T1/2) and the junction-shift sc3hedule in craniospinal irradiation (CSI). METHODS: CSI was planned retrospectively, and the NTCP of the spinal cord was calculated with the IR model for values of T1/2 from 1 to 10 h. The NTCP in the case of changing the junction shift schedule was also examined in the same manner. RESULTS: The NTCP with the IR model increased with increasing T1/2, which is prominent for the larger T1/2. By changing the junction-shift schedule, the NTCP with the IR model decreased when adjacent fields overlapped. CONCLUSIONS: The IR model is a valuable addition to treatment planning because it enables the NTCP to be evaluated including the effect of repair and differences in scheduling to be reflected in the NTCP. However, these are largely dependent on the value of the T1/2. PMID- 29471860 TI - Urinary phthalate metabolites in relation to serum anti-Mullerian hormone and inhibin B levels among women from a fertility center: a retrospective analysis. AB - BACKGROUND: Phthalates, a class of endocrine disruptors, have been demonstrated to accelerate loss of ovarian follicle pool via disrupting folliculogenesis, and lead to diminished ovarian reserve. However, human data are limited. Here, we aimed to examine whether urinary phthalate metabolites are correlated with markers of ovarian reserve among women attending a fertility clinic. METHODS: We measured eight phthalate metabolites in urine samples collected from 415 women seeking infertility treatment at the Reproductive Medicine Center of Tongji Hospital, Wuhan, China. Data on measures of ovarian reserve, as indicated by serum anti-Mullerian hormone (AMH) and inhibin B (INHB) levels, were retrieved retrospectively through electronic medical charts. Multivariate linear models were performed to estimate the associations of urinary phthalate metabolites and serum AMH and INHB. We further explored the potential nonlinearity of the relationships with restricted cubic spline analysis. RESULTS: Overall, we found largely null associations between urinary phthalate metabolites and serum AMH. The multivariable adjusted differences in serum INHB levels comparing the highest quartile of urinary MEHP to the lowest were - 18.29% (95% CI: - 31.89%, - 1.98%; P-trend = 0.04). Women in the second to fourth quartiles of MEOHP had a significant decrease of - 23.74% (95% CI: -35.85%, - 9.24%), - 19.91% (95% CI: 33.30%, - 3.82%) and - 20.23% (95% CI: -34.43%, - 2.96%), respectively, in INHB levels compared to the first quartile. In the spline analysis, we identified a nonlinear relationship between MEOHP exposure and serum INHB. CONCLUSIONS: We provided evidence for a negative association between urinary concentrations of certain phthalate metabolites and serum INHB levels, suggesting an adverse effect of phthalates exposure on growing antral follicles. Whether phthalates exposure at environmentally level will pose a risk for ovarian reserve needs further investigation. PMID- 29471861 TI - Investigating the effectiveness and cost-effectiveness of FITNET-NHS (Fatigue In Teenagers on the interNET in the NHS) compared to Activity Management to treat paediatric chronic fatigue syndrome (CFS)/myalgic encephalomyelitis (ME): protocol for a randomised controlled trial. AB - BACKGROUND: Paediatric chronic fatigue syndrome or myalgic encephalomyelitis (CFS/ME) is a relatively common and disabling condition. The National Institute for Health and Clinical Excellence (NICE) recommends Cognitive Behavioural Therapy (CBT) as a treatment option for paediatric CFS/ME because there is good evidence that it is effective. Despite this, most young people in the UK are unable to access local specialist CBT for CFS/ME. A randomised controlled trial (RCT) showed FITNET was effective in the Netherlands but we do not know if it is effective in the National Health Service (NHS) or if it is cost-effective. This trial will investigate whether FITNET-NHS is clinically effective and cost effective in the NHS. METHODS: Seven hundred and thirty-four paediatric patients (aged 11-17 years) with CFS/ ME will be randomised (1:1) to receive either FITNET NHS (online CBT) or Activity Management (delivered via video call). The internal pilot study will use integrated qualitative methods to examine the feasibility of recruitment and the acceptability of treatment. The full trial will assess whether FITNET-NHS is clinically effective and cost-effective. The primary outcome is disability at 6 months, measured using the SF-36-PFS (Physical Function Scale) questionnaire. Cost-effectiveness is measured via cost-utility analysis from an NHS perspective. Secondary subgroup analysis will investigate the effectiveness of FITNET-NHS in those with co-morbid mood disorders. DISCUSSION: If FITNET-NHS is found to be feasible and acceptable (internal pilot) and effective and cost-effective (full trial), its provision by the NHS has the potential to deliver substantial health gains for the large number of young people suffering from CFS/ME but unable to access treatment because there is no local specialist service. This trial will provide further evidence evaluating the delivery of online CBT to young people with chronic conditions. TRIAL REGISTRATION: ISRCTN registry, registration number: ISRCTN18020851 . Registered on 4 August 2016. PMID- 29471862 TI - Human-Forest interfaces in Hugumburda-Gratkhassu National Forest Priority Area, North-eastern Ethiopia. AB - BACKGROUND: Traditional management regimes and knowledge systems of forest resources have shaped forests throughout the world where materials from individual species are harvested in a sustainable manner. To comprehend this, the vegetation of Hugumburda-Gratkhassu Forest was described and related to anthropogenic factors. METHODS: Three ethnobotanical research methods were used to collect indigenous knowledge of the local inhabitants related to conservation and utilization of forest resources. Direct matrix ranking was conducted to discover local attitudes on species preference for multiple use. During this work, the 46 most important tree and shrub species were selected based on recommendations of local guides and key informants to determine the range of uses obtained from each species. Through paired comparison, activities supposed to be the major cause of degradation of the forest were adopted. Pairs of activities were then established from the relation n (n-1)/2. Each respondent was then asked to select an activity that he considered being a major problem to management of the forest. Semi-structured interviews were used to obtain information from sixty local informants to address community attitudes towards forest management and utilization. RESULTS: The result obtained from direct matrix ranking showed; that 20 out of 46 plant species compared had the highest scores and rank, indicating that these species are the most important and are exploited by the local communities for multiple purposes. The paired comparison exercise revealed logging for construction materials to be the major threat to the forest due to cutting of large volume of wood for construction of churches, health centers, schools and new houses. Juniperus procera, Olea europaea ssp. cuspidata, Rhus glutinosa, Ficus sur, Hagenia abyssinica, Cassipourea malosana and Acacia etbaica were the most selected and exploited plant species for these purposes. CONCLUSIONS: Survival of protected areas depends on the support of local communities, rather than on fences, fines, or even force. The local communities in the study area have a rich indigenous ecological knowledge to suggest appropriate solutions for improvement of the forest resources. Thus the old tradition of isolating forests from the community has to be avoided and the basic needs and traditional rights of the communities over the uses of forest resources should be recognized. PMID- 29471863 TI - The microbiome in precision medicine: the way forward. AB - Novel associations between the human microbiome and health and disease are routinely emerging, and important host-microbiome interactions are targets for new diagnostics and therapeutics. Understanding how broadly host-microbe associations are maintained across populations is revealing individualized host microbiome phenotypes that can be integrated with other 'omics' data sets to enhance precision medicine. PMID- 29471864 TI - In tune with nature: Wolbachia does not prevent pre-copula acoustic communication in Aedes aegypti. AB - BACKGROUND: Mosquito-borne diseases are rapidly spreading to vast territories, putting at risk most of the world's population. A key player in this scenario is Aedes aegypti, a hematophagous species which hosts and transmits viruses causing dengue and other serious illnesses. Since vector control strategies relying only on insecticides have proven unsustainable, an alternative method involving the release of Wolbachia-harboring individuals has emerged. Its successful implementation vastly depends on how fit the released individuals are in the natural habitat, being able to mate with wild populations and to spread Wolbachia to subsequent generations. In mosquitoes, an important aspect of reproductive fitness is the acoustic communication between males and females, which translates to interactions between harmonic frequencies in close proximity flight. This study aimed to characterize the flight tone produced by individuals harboring Wolbachia, also evaluating their ability to establish stable acoustic interactions. METHODS: Wild-type (WT) and Wolbachia-harboring specimens (wMelBr) were thorax-tethered to blunt copper wires and placed at close proximity to sensitive microphones. Wing-beat frequencies (WBFs) were characterized at fundamental and harmonic levels, for both single individuals and couples. Harmonic interactions in homogeneous and heterogeneous couples of WT and wMelBr variants were identified, categorized and quantified accordingly. RESULTS: In tethered 'solo' flights, individuals harboring Wolbachia developed WBFs, differing slightly, in a sex-dependent way, from those of the WT strain. To test the ability to form harmonic 'duets', tethered couples of wMelBr and WT individuals were shuffled in different sex pairs and had their flight tones analyzed. All couple types, with WT and/or wMelBr individuals, were able to interact acoustically in the frequency range of 1300-1500 Hz, which translates to the convergence between male's second harmonic and female's third. No significant differences were found in the proportions of interacting couples between the pair types. Surprisingly, spectrograms also revealed the convergence between alternative harmonic frequencies, inside and outside the species putative hearing threshold. CONCLUSIONS: Wolbachia infection leads to small sex-dependent changes on the flight tones of Ae. aegypti, but it does not seem to prevent the stereotyped harmonic interaction between males and females. Therefore, when released in the natural habitat to breed with native individuals, Wolbachia harboring individuals shall be fit enough to meet the criteria of acoustically related mating behavior and promote bacteria dispersion effectively. PMID- 29471865 TI - A multicentre, randomised, non-inferiority clinical trial comparing a nifurtimox eflornithine combination to standard eflornithine monotherapy for late stage Trypanosoma brucei gambiense human African trypanosomiasis in Uganda. AB - BACKGROUND: While the combination of nifurtimox and eflornithine (NECT) is currently recommended for the treatment of the late stage human African trypansomiasis (HAT), single-agent eflornithine was still the treatment of choice when this trial commenced. This study intended to provide supportive evidence to complement previous trials. METHODS: A multi-centre randomised, open-label, non inferiority trial was carried out in the Trypanosoma brucei gambiense endemic districts of North-Western Uganda to compare the efficacy and safety of NECT (200 mg/kg eflornithine infusions every 12 h for 7 days and 8 hourly oral nifurtimox at 5 mg/kg for 10 days) to the standard eflornithine regimen (6 hourly at 100 mg/kg for 14 days). The primary endpoint was the cure rate, determined as the proportion of patients alive and without laboratory signs of infection at 18 months post-treatment, with no demonstrated trypanosomes in the cerebrospinal fluid (CSF), blood or lymph node aspirates, and CSF white blood cell count < 20 /MUl. The non-inferiority margin was set at 10%. RESULTS: One hundred and nine patients were enrolled; all contributed to the intent-to-treat (ITT), modified intent-to-treat (mITT) and safety populations, while 105 constituted the per protocol population (PP). The cure rate was 90.9% for NECT and 88.9% for eflornithine in the ITT and mITT populations; the same was 90.6 and 88.5%, respectively in the PP population. Non-inferiority was demonstrated for NECT in all populations: differences in cure rates were 0.02 (95% CI: -0.07-0.11) and 0.02 (95% CI: -0.08-0.12) respectively. Two patients died while on treatment (1 in each arm), and 3 more during follow-up in the NECT arm. No difference was found between the two arms for the secondary efficacy and safety parameters. A meta-analysis involving several studies demonstrated non-inferiority of NECT to eflornithine monotherapy. CONCLUSIONS: These results confirm findings of earlier trials and support implementation of NECT as first-line treatment for late stage T. b. gambiense HAT. The overall risk difference for cure between NECT and eflornithine between this and two previous randomised controlled trials is 0.03 (95% CI: -0.02-0.08). The NECT regimen is simpler, safer, shorter and less expensive than single-agent DFMO. TRIAL REGISTRATION: ISRCTN ISRCTN03148609 (registered 18 April 2008).

PMID- 29471867 TI - Earplugs in the ICU: To sleep, to dream. PMID- 29471868 TI - Asymptomatic thyroiditis presenting as pyrexia of unknown origin: a case report. AB - BACKGROUND: Pyrexia of unknown origin is a difficult and challenging problem for the physician. Endocrine disorders, such as subacute thyroiditis, rarely present with pyrexia of unknown origin. Subacute thyroiditis can have a broad spectrum of clinical presentations including fever and biochemical thyrotoxicosis without overt signs or symptoms. CASE PRESENTATION: A previously healthy 42-year-old Sri Lankan Sinhalese man was extensively investigated for a prolonged fever of 3 weeks with high inflammatory markers. He had mild tenderness over his neck with cervical lymphadenopathy with no thyrotoxic symptoms or signs. An ultrasound scan revealed an enlarged thyroid with increased vascularity and he had suppressed thyroid-stimulating hormone with elevated free thyroxine and free triiodothyronine hormone levels. Fine-needle aspiration cytology confirmed thyroiditis. He responded well to low-dose steroids. CONCLUSION: Subacute thyroiditis should be considered in the diagnostic workup of pyrexia of unknown origin even in the absence of overt toxic symptoms of thyroid hormone excess. PMID- 29471870 TI - Autologous bone marrow-derived mononuclear cell therapy in Chinese patients with critical limb ischemia due to thromboangiitis obliterans: 10-year results. AB - BACKGROUND: For patients with thromboangiitis obliterans (TAO), revascularization with bypass or angioplasty is frequently not feasible due to the poor outflow of the distal small vessels. We evaluated the long-term results of our experience treating patients with TAO with autologous bone marrow-derived mononuclear cells (ABMMNCs) to determine the safety and efficacy of ABMMNC therapy in patients with critical limb ischemia due to TAO. METHODS: This was a retrospective chart review from a single university hospital vascular surgery center between January 2005 and July 2006. Patients were treated with smoking cessation and either aspirin (100 mg/day) alone or aspirin and ABMMNC injection according to patient preference. Groups were compared for demographics, clinical characteristics, and short-term and long-term results. RESULTS: Of 59 patients with TAO who were treated, 19 patients elected aspirin alone and 40 patients elected aspirin and ABMMNC injection. No patients suffered perioperative complications and 49 (83%) patients remained smoke-free for 10 years. The 10-year amputation-free survival was 85.3% (29/34) in patients treated with ABMMNCs compared to 40% (6/15) in patients treated with aspirin alone (p = 0.0019). Ulcer area (p < 0.0001), toe brachial index (TBI; p < 0.0001), transcutaneous oxygen pressure (TcPO2; p < 0.0001), and pain score (p < 0.0001) were also significantly improved with ABMMNC treatment, although there was no difference in mean ankle-brachial index (ABI; p = 0.806). CONCLUSIONS: In patients with critical limb ischemia due to TAO, ABMMNC treatment was safe and effective. ABMMNC treatment significantly improved amputation-free survival, ulcer healing, and pain, although there is no difference in ABI compared to treatment with aspirin alone.

PMID- 29471869 TI - Type 2 diabetes impairs odour detection, olfactory memory and olfactory neuroplasticity; effects partly reversed by the DPP-4 inhibitor Linagliptin. AB - Recent data suggest that olfactory deficits could represent an early marker and a pathogenic mechanism at the basis of cognitive decline in type 2 diabetes (T2D). However, research is needed to further characterize olfactory deficits in diabetes, their relation to cognitive decline and underlying mechanisms.The aim of this study was to determine whether T2D impairs odour detection, olfactory memory as well as neuroplasticity in two major brain areas responsible for olfaction and odour coding: the main olfactory bulb (MOB) and the piriform cortex (PC), respectively. Dipeptidyl peptidase-4 inhibitors (DPP-4i) are clinically used T2D drugs exerting also beneficial effects in the brain. Therefore, we aimed to determine whether DPP-4i could reverse the potentially detrimental effects of T2D on the olfactory system.Non-diabetic Wistar and T2D Goto-Kakizaki rats, untreated or treated for 16 weeks with the DPP-4i linagliptin, were employed. Odour detection and olfactory memory were assessed by using the block, the habituation-dishabituation and the buried pellet tests. We assessed neuroplasticity in the MOB by quantifying adult neurogenesis and GABAergic inhibitory interneurons positive for calbindin, parvalbumin and carletinin. In the PC, neuroplasticity was assessed by quantifying the same populations of interneurons and a newly identified form of olfactory neuroplasticity mediated by post-mitotic doublecortin (DCX) + immature neurons.We show that T2D dramatically reduced odour detection and olfactory memory. Moreover, T2D decreased neurogenesis in the MOB, impaired the differentiation of DCX+ immature neurons in the PC and altered GABAergic interneurons protein expression in both olfactory areas. DPP-4i did not improve odour detection and olfactory memory. However, it normalized T2D-induced effects on neuroplasticity.The results provide new knowledge on the detrimental effects of T2D on the olfactory system. This knowledge could constitute essentials for understanding the interplay between T2D and cognitive decline and for designing effective preventive therapies.

AB - OBJECTIVES: microRNAs regulate expression of target genes by specifically binding to their transcripts, subsequently leading to translational inhibition or mRNA degradation. Gene regulation by microRNAs has been implicated in a wide range of physiological and pathological conditions. Here, we leverage the use of public access data and the available genomic annotations to pre-calculate the correlation of the expression of a large number of microRNAs with gene at the mRNA and protein level in the context of cancers. RESULTS: Expression data of miRNAs, mRNAs and proteins in cancer patients from The Cancer Genome Atlas along with TargetScan miRNAs-target annotations were used to calculate the expression correlations between miRNAs and features (mRNAs/proteins) in a number of cancer studies. We then packed the output of this analysis into a database and made it available through an interactive web application. The miRCancerdb is an easy-to use database to investigate the microRNAs-dependent regulation of target genes involved in development of cancer. PMID- 29471872 TI - A reservoir of 'historical' antibiotic resistance genes in remote pristine Antarctic soils. AB - BACKGROUND: Soil bacteria naturally produce antibiotics as a competitive mechanism, with a concomitant evolution, and exchange by horizontal gene transfer, of a range of antibiotic resistance mechanisms. Surveys of bacterial resistance elements in edaphic systems have originated primarily from human impacted environments, with relatively little information from remote and pristine environments, where the resistome may comprise the ancestral gene diversity. METHODS: We used shotgun metagenomics to assess antibiotic resistance gene (ARG) distribution in 17 pristine and remote Antarctic surface soils within the undisturbed Mackay Glacier region. We also interrogated the phylogenetic placement of ARGs compared to environmental ARG sequences and tested for the presence of horizontal gene transfer elements flanking ARGs. RESULTS: In total, 177 naturally occurring ARGs were identified, most of which encoded single or multi-drug efflux pumps. Resistance mechanisms for the inactivation of aminoglycosides, chloramphenicol and beta-lactam antibiotics were also common. Gram-negative bacteria harboured most ARGs (71%), with fewer genes from Gram positive Actinobacteria and Bacilli (Firmicutes) (9%), reflecting the taxonomic composition of the soils. Strikingly, the abundance of ARGs per sample had a strong, negative correlation with species richness (r = - 0.49, P < 0.05). This result, coupled with a lack of mobile genetic elements flanking ARGs, suggests that these genes are ancient acquisitions of horizontal transfer events. CONCLUSIONS: ARGs in these remote and uncontaminated soils most likely represent functional efficient historical genes that have since been vertically inherited over generations. The historical ARGs in these pristine environments carry a strong phylogenetic signal and form a monophyletic group relative to ARGs from other similar environments.

PMID- 29471875 TI - Pre-treatment DWI as a predictor of overall survival in locally advanced pancreatic cancer treated with Cyberknife radiotherapy and sequential S-1 therapy. AB - BACKGROUND: To identify the value of the pre-treatment apparent diffusion coefficient (ADC) derived from diffusion weighted imaging (DWI) in predicting the overall survival (OS) for locally advanced pancreatic cancer (LAPC) treated with Cyberknife followed by sequential S-1 chemotherapy. METHODS: Patients with UICC T4 LAPC who underwent DWI scan (3.0 Tesla) using two b-values (0, 600 s/mm2) in our center between 2015 and 2017 were enrolled. Mean ADCs of the region of interest (ROI) drawn manually on DWI imaging were measured by two independent radiologists at an interval of 1 month. The association between prognostic factors and patient survival was determined using univariate and multivariate analyses. Cox proportional hazard model was used for identification of independent prognostic factors of OS. RESULTS: A total of 41 patients (28 males and 13 females) were included, with a median age of 64 years, with 5 patients (3 males and 2 females) lost. The median OS was 11.7 months (range 2.8-23.3) among all 41 patients. The 1-year OS was 46% (95% CI 30%-62%). Univariate and multivariate analyses indicated that pre-treatment ADC value (HR 10.652, P = 0.0093), age (HR 0.952, P = 0.015), CA19-9 (HR 1.001, P = 0.0022) and administration of S-1 (HR 0.128, P = 0.0002) were independent predicting factors of OS. CONCLUSION: The mean ADC value of the primary tumor on pre-treatment DWI imaging was an independent predictor of OS in patients with LAPC receiving Cyberknife followed by sequential S-1. PMID- 29471876 TI - Effect of propranolol on heart rate variability in hyperthyroidism. AB - OBJECTIVES: We aimed to determine the effect of propanolol on heart rate variability (HRV) in hyperthyroidism before antithyroid treatment. This was a before and after study, on ten patients presenting overt hyperthyroidism naive to treatment. In each patient, a resting electrocardiogram was done followed by estimation of cardiac autonomic dysfunction during five maneuvers (Ewing battery tests). Long term HRV measurement was done using 24 h ambulatory electrocardiographic recording. This automatically provided estimation of HRV using SDNN and RMSSD index, LF, HF, and HF/LF ratio. After baseline investigations, 40 mg of propanolol was given twice a day for 3 days and same parameters were measured after 72 h of treatment. RESULTS: Our patients were aged 40 +/- 10 years. Propanolol significantly reduced RR and HR interval (669 ms vs 763 ms and 91 vs 79 bpm; p < 0.01). QT and PR space were significantly extended (360 vs 384 ms and 133 vs 172 ms; p = 0.01). It increases QRS complex and blood pressure response to sustained handgrip but failed to modify previously decreased heart response to deep breathing. HRV parameters such as SDNN, RMSSD, LF, HF and sympathovagal balance estimate by HF/LF ratio remained unchanged. Although a significant reduction in heart excitability, propanolol failed to restore a good sympathovagal balance in hyperthyroidism. Trial registration NCT03393728 "Retrospectively registered". PMID- 29471877 TI - A personalized intervention to prevent depression in primary care: cost effectiveness study nested into a clustered randomized trial. AB - BACKGROUND: Depression is viewed as a major and increasing public health issue, as it causes high distress in the people experiencing it and considerable financial costs to society. Efforts are being made to reduce this burden by preventing depression. A critical component of this strategy is the ability to assess the individual level and profile of risk for the development of major depression. This paper presents the cost-effectiveness of a personalized intervention based on the risk of developing depression carried out in primary care, compared with usual care. METHODS: Cost-effectiveness analyses are nested within a multicentre, clustered, randomized controlled trial of a personalized intervention to prevent depression. The study was carried out in 70 primary care centres from seven cities in Spain. Two general practitioners (GPs) were randomly sampled from those prepared to participate in each centre (i.e. 140 GPs), and 3326 participants consented and were eligible to participate. The intervention included the GP communicating to the patient his/her individual risk for depression and personal risk factors and the construction by both GPs and patients of a psychosocial programme tailored to prevent depression. In addition, GPs carried out measures to activate and empower the patients, who also received a leaflet about preventing depression. GPs were trained in a 10- to 15-h workshop. Costs were measured from a societal and National Health care perspective. Qualityadjustedlife years were assessed using the EuroQOL five dimensions questionnaire. The time horizon was 18 months. RESULTS: With a willingness-to-pay threshold of ?10,000 (L8568) the probability of cost effectiveness oscillated from 83% (societal perspective) to 89% (health perspective). If the threshold was increased to ?30,000 (L25,704), the probability of being considered cost-effective was 94% (societal perspective) and 96%, respectively (health perspective). The sensitivity analysis confirmed these results. CONCLUSIONS: Compared with usual care, an intervention based on personal predictors of risk of depression implemented by GPs is a cost-effective strategy to prevent depression. This type of personalized intervention in primary care should be further developed and evaluated. TRIAL REGISTRATION: ClinicalTrials.gov, NCT01151982. Registered on June 29, 2010. PMID- 29471878 TI - Objective assessment of physical activity and sedentary behaviour in knee osteoarthritis patients - beyond daily steps and total sedentary time. AB - BACKGROUND: Knee osteoarthritis patients may become physically inactive due to pain and functional limitations. Whether physical activity exerts a protective or harmful effect depends on the frequency, intensity, time and type (F.I.T.T.). The F.I.T.T. dimensions should therefore be assessed during daily life, which so far has hardly been feasible. Furthermore, physical activity should be assessed within subgroups of patients, as they might experience different activity limitations. Therefore, this study aimed to objectively describe physical activity, by assessing the F.I.T.T. dimensions, and sedentary behaviour of knee osteoarthritis patients during daily life. An additional goal was to determine whether activity events, based on different types and durations of physical activity, were able to discriminate between subgroups of KOA patients based on risk factors. METHODS: Clinically diagnosed knee osteoarthritis patients (according to American College of Rheumatology criteria) were monitored for 1 week with a tri-axial accelerometer. Furthermore, they performed three functional tests and completed the Knee Osteoarthritis Outcome Score. Physical activity levels were described for knee osteoarthritis patients and compared between subgroups. RESULTS: Sixty-one patients performed 7303 mean level steps, 319 ascending and 312 descending steps and 601 bicycle crank revolutions per day. Most waking hours were spent sedentary (61%), with 4.6 bouts of long duration (> 30 min). Specific events, particularly ascending and descending stairs/slopes, brief walking and sedentary bouts and prolonged walking bouts, varied between subgroups. CONCLUSIONS: From this sample of KOA patients, the most common form of activity was level walking, although cycling and stair climbing activities occurred frequently, highlighting the relevance of distinguishing between these types of PA. The total active time encompassed a small portion of their waking hours, as they spent most of their time sedentary, which was exacerbated by frequently occurring prolonged bouts. In this study, event-based parameters, such as stair climbing or short bouts of walking or sedentary time, were found more capable of discriminating between subgroups of KOA patients compared to overall levels of PA and sedentary time. Thereby, subtle limitations in physical behaviour of KOA-subgroups were revealed, which might ultimately be targeted in rehabilitation programs.

PMID- 29471879 TI - Dosimetric impact of tumor treating field (TTField) transducer arrays onto treatment plans for glioblastomas - a planning study. AB - BACKGROUND: Tumor-Treating Fields (TTFields) are a novel treatment strategy for glioblastoma (GBM) that is approved for the use concomitantly to adjuvant chemotherapy. Preclinical data suggest a synergistic interaction of TTFields and radiotherapy (RT). However, the dosimetric uncertainties caused by the highly dense arrays have led to caution of applying the TTF setup during RT. METHODS: In a RW3 slab phantom we compared the MV- and kV-CT based planned dose with the measured dose. VMAT-plans were optimized on MV-CTs of an Alderson head phantom without TTF arrays and then re-calculated on the same phantom equipped with TTF arrays. Dose at organs at risk (OAR) and target volumes (PTVs) were compared. RESULTS: Measurements at a depth of 2, 3 and 4 cm of a RW 3 slab phantom show an attenuation due to TTField arrays of 3.4, 3.7 and 2.7% respectively. This was in line with calculated attenuations based on MV-CT (1.2, 2.5 and 2.5%) but not with the attenuation expected from kV-CT based calculations (7.1, 8.2 and 8.6%). Consecutive MV-CT based VMAT planning and re-calculation reveals, that the conformity and homogeneity are not affected by the presence of TTField arrays. The dose at organs at risk (OAR) can show increases or decreases by < 0.5 Gy, which should be considered especially in cases next to the scull base. CONCLUSION: MV-CT based dose calculation results in reliable dose distributions also in the presence of TTField arrays. There is a small but clinically not relevant interaction between the TTField arrays and VMAT dose application. Thus, daily replacement of TTField arrays is not necessary in regard to deeply located OARs. RT is feasible, when a VMAT treatment plan is optimized to an array free planning CT. As the biologic effect of a concomitant treatment especially on OARs is currently unknown, a concomitant treatment should be performed only within clinical trials. PMID- 29471880 TI - [18F]FSPG-PET reveals increased cystine/glutamate antiporter (xc-) activity in a mouse model of multiple sclerosis. AB - BACKGROUND: The cystine/glutamate antiporter (xc-) has been implicated in several neurological disorders and, specifically, in multiple sclerosis (MS) as a mediator of glutamate excitotoxicity and proinflammatory immune responses. We aimed to evaluate an xc-specific positron emission tomography (PET) radiotracer, (4S)-4-(3-[18F]fluoropropyl)-L-glutamate ([18F]FSPG), for its ability to allow non-invasive monitoring of xc- activity in a mouse model of MS. METHODS: Experimental autoimmune encephalomyelitis (EAE) was induced in C57BL/6 mice by subcutaneous injection of myelin oligodendrocyte glycoprotein (MOG35-55) peptide in complete Freund's adjuvant (CFA) followed by pertussis toxin. Control mice received CFA emulsion and pertussis toxin without MOG peptide, while a separate cohort of naive mice received no treatment. PET studies were performed to investigate the kinetics and distribution of [18F]FSPG in naive, control, pre symptomatic, and symptomatic EAE mice, compared to 18F-fluorodeoxyglucose ([18F]FDG). After final PET scans, each mouse was perfused and radioactivity in dissected tissues was measured using a gamma counter. Central nervous system (CNS) tissues were further analyzed using ex vivo autoradiography or western blot. [18F]FSPG uptake in human monocytes, and T cells pre- and post-activation was investigated in vitro. RESULTS: [18F]FSPG was found to be more sensitive than [18F]FDG at detecting pathological changes in the spinal cord and brain of EAE mice. Even before clinical signs of disease, a small but significant increase in [18F]FSPG signal was observed in the spinal cord of EAE mice compared to controls. This increase in PET signal became more pronounced in symptomatic EAE mice and was confirmed by ex vivo biodistribution and autoradiography. Likewise, in the brain of symptomatic EAE mice, [18F]FSPG uptake was significantly higher than controls, with the largest changes observed in the cerebellum. Western blot analyses of CNS tissues revealed a significant correlation between light chain of xc- (xCT) protein levels, the subunit of xc- credited with its transporter activity, and [18F]FSPG-PET signal. In vitro [18F]FSPG uptake studies suggest that both activated monocytes and T cells contribute to the observed in vivo PET signal. CONCLUSION: These data highlight the promise of [18F]FSPG-PET as a technique to provide insights into neuroimmune interactions in MS and the in vivo role of xc- in the development and progression of this disease, thus warranting further investigation. PMID- 29471881 TI - Evaluation of the long-term efficacy of K-Othrine(r) PolyZone on three surfaces against laboratory reared Anopheles gambiae in semi-field conditions. AB - BACKGROUND: In this semi-field study, a new polymer-enhanced deltamethrin formulation, K-Othrine(r) PolyZone, was compared to a standard deltamethrin product for residual activity against a susceptible strain of laboratory-reared Anopheles gambiae using standard WHO cone bioassays. METHODS: Residual insecticide efficacy was recorded after exposure to metal, cement and wood panels maintained in experimental huts in sub-tropical environmental conditions in north central Florida, USA, and panels stored in a climate controlled chamber located at the Centers for Disease Control and Prevention, Georgia, USA. CONCLUSIONS: K Othrine(r) PolyZone demonstrated 100% control on metal and cement panels 1 year post application and > 80% control on wood panels up to 6 mo. The new formulation should be considered for use in indoor residual spray programmes requiring long term control of malaria vectors. PMID- 29471882 TI - The use of Latin terminology in medical case reports: quantitative, structural, and thematic analysis. AB - BACKGROUND: This paper focuses on the prevalence of Latin terms and terminological collocations in the issues of Journal of Medical Case Reports (February 2007-August 2017) and discusses the role of Latin terminology in the contemporary process of writing medical case reports. METHODS: The objective of the research is to study the frequency of using Latin terminology in English language medical case reports, thus providing relevant guidelines for medical professionals who deal with this genre and drawing their attention to the peculiarities of using Latin in case reports. The selected medical case reports are considered, using methods of quantitative examination and structural, narrative, and contextual analyses. RESULTS: We developed structural and thematic typologies of Latin terms and expressions, and we conducted a quantitative analysis that enabled us to observe the tendencies in using these lexical units in medical case reports. The research revealed that the use of Latin fully complies with the communicative strategies of medical case reports as a genre. Owing to the fact that Latin medical lexis is internationally adopted and understood worldwide, it promotes the conciseness of medical case reports, as well as contributes to their narrative style and educational intentions. CONCLUSIONS: The adequate use of Latin terms in medical case reports is an essential prerequisite of effective sharing of one's clinical findings with fellow researchers from all over the world. Therefore, it is highly important to draw students' attention to Latin terms and expressions that are used in medical case reports most frequently. Hence, the analysis of structural, thematic, and contextual features of Latin terms in case reports should be an integral part of curricula at medical universities. PMID- 29471883 TI - The extremity localized classic osteosarcomas have better survival than the axial non-classics. AB - BACKGROUND: Osteosarcoma is one of the most malignant primary bone cancers, while is rarely reported in China. Of note, very few data of prognosis has been documented in this region. Thus, we carried a retrospective study to identify prognostic factors and to analyze outcomes in patients of both classic and non classic high-grade osteosarcomas. Classic osteosarcoma is defined as of high grade histology, age below 40 years, with extremity localized primary tumor, and without detectable metastasis at primary diagnosis. METHODS: A total of 98 patients (68 classic and 30 non-classic) aged from 4 to 64 years old were diagnosed as high-grade osteosarcoma from 2008 to 2015 in Nanfang Hospital, Guangzhou, China. Univariate and multivariate analyses were performed to identify the independent predictors for overall survival and event-free survival. Kaplan Meier method was used for survival analysis. RESULTS: The median overall survival was 117 vs. 21 months, and the median event-free survival was 31 vs. 6 months in classic and non-classic osteosarcoma, respectively. The most frequently found tumor site was around the knee. The classic osteosarcoma had better overall survival and event-free survival than the non-classics. Tumor site and primary metastasis were found to be associated with overall survival and event-free survival in the univariate analysis. In the multivariate Cox regression analysis, tumor site and primary metastasis were each verified as independent prognostic factors. However, no similar result was found in elevated serum alkaline phosphatase or lactate dehydrogenase. Amputation or limb salvage surgery had no significant effect on overall survival and event-free survival in the extremity osteosarcomas. Classic osteosarcomas with extremity tumor site and free of primary metastasis exhibited better overall survival and event-free survival, while the axial and metastatic non-classics exhibited the worse. CONCLUSIONS: The extremity classic osteosarcomas have better survivals than the axial non-classic cases. Amputation and limb salvage surgery make no significant change in overall survival and event-free survival in the extremity osteosarcomas.

PMID- 29471886 TI - LncRNA NORAD contributes to colorectal cancer progression by inhibition of miR 202-5p. AB - Previous study indicates that long noncoding RNA NORAD could serve as a competing endogenous RNA to pancreatic cancer metastasis. However, its role in colorectal cancer requires to be investigated. In the present study, we found that the expression of NORAD was significantly upregulated in colorectal cancer (CRC) tissues. Furthermore, the expression of NORAD was positively related with CRC metastasis and patients' poor prognosis. Knockdown of NORAD markedly inhibited CRC cell proliferation, migration and invasion but induced cell apoptosis in vitro. In vivo experiments also indicated an inhibitory effect of NORAD on tumor growth. In mechanism, we found that NORAD served as a competing endogenous RNA for miR-202-5p. We found that there was an inversely relationship between the expression of NORAD and miR-202-5p in CRC tissues. Moreover, overexpression of miR-202-5p in SW480 and HCT116 cells significantly inhibited cellular proliferation, migration and invasion. Taken together, our study demonstrated NORAD/miR-202-5p axis plays a pivot function on CRC progression. PMID- 29471887 TI - Long non-coding RNA CCAL promotes papillary thyroid cancer progression by activation of NOTCH1 pathway. AB - Long non-coding RNA CCAL has been reported to promote tumor progression in various human cancers, including hepatocellular carcinoma, osteosarcoma, and colorectal cancer. However, the role of CCAL in papillary thyroid cancer remains largely unknown. In the present study, we found that the expression of CCAL was upregulated in papillary thyroid tumor tissues compared to adjacent normal tissues. Moreover, the expression of CCAL was positively related with papillary thyroid cancer severity and TNM stage, and predicated poor prognosis. Besides, we found that knockdown of CCAL significantly inhibited papillary thyroid cancer cell proliferation, migration and invasion in vitro and reduced tumor growth and metastasis in vivo. In mechanism, we found that knockdown of CCAL dramatically decreased the expression of NOTCH1 and suppressed the activation of NOTCH1 signaling pathway. Furthermore, Overexpression of NOTCH1 rescued the proliferation, migration and invasion in papillary thyroid cancer cells. Taken together, our data indicated that CCAL promoted papillary thyroid cancer development and progression by activation of NOTCH1 pathway, which provided a new insight on the design of therapeutic targets. PMID- 29471885 TI - Does bird metabolic rate influence mosquito feeding preference? AB - BACKGROUND: Host selection by mosquitoes plays a central role in the transmission of vector-borne infectious diseases. Although interspecific variation in mosquito attraction has often been reported, the mechanisms underlying intraspecific differences in hosts' attractiveness to mosquitoes are still poorly known. Metabolic rate is related to several physiological parameters used as location cues by mosquitoes, and so potentially affect host-vector contact rates. Therefore, individual hosts with higher metabolic rates should be more attractive to host-seeking mosquitoes. Here, we experimentally investigated the role of bird metabolic rate in the feeding preferences of Culex pipiens (Linnaeus), a widespread mosquito vector of many pathogens affecting human and wildlife health. RESULTS: Passer domesticus (Linnaeus) pairs containing one bird treated with 2,4 dinitrophenol (DNP) and the other injected with phosphate-buffered saline solution (PBS) (i.e. control) were simultaneously exposed overnight to mosquitoes. The treatment did not affect the proportion of mosquitoes biting on each individual. However, mosquito feeding preference was negatively associated with bird resting metabolic rate but positively with bird body mass. These two variables explained up to 62.76% of the variations in mosquito feeding preference. CONCLUSIONS: The relationships between mosquito feeding preferences and individual host characteristics could be explained by enhanced anti-mosquito behaviour associated with higher metabolic rates. The potential role of cues emitted by hosts is also discussed. Thus, individuals with high metabolism may actively avoid being bitten by mosquitoes, despite releasing more attractant cues. Since metabolic rates can be related to individual differences in personality and life history traits, differences in mosquitoes' feeding preferences may be related to intraspecific differences in exposure to vector borne pathogens. PMID- 29471888 TI - Liquiritigenin inhibits colorectal cancer proliferation, invasion and epithelial to mesenchymal transition by decreasing expression of runt-related transcription factor 2. AB - Inhibition of tumor metastasis is one of the most important purposes in colorectal cancer (CRC) treatment. This study aimed to explore the effects of liquiritigenin, one of flavonoids extracted from the roots of Glycyrrhiza uralensis Fisch, on HCT116 cell proliferation, invasion, and epithelial to mesenchymal transition (EMT). We found that liquiritigenin significantly inhibited HCT116 cell proliferation, invasion and EMT process but had no influence on cell apoptosis. Moreover, liquiritigenin remarkably reduced the expression of runt-related transcription factor 2 (Runx2) in HCT116 cells. Overexpression of Runx2 obviously reversed the liquiritigenin-induced invasion and EMT inhibition. Furthermore, liquiritigenin inactivated the phosphoinositide 3-kinase/protein kinase B (PI3K/AKT) pathway in HCT116 cells. Up-regulation of Runx2 reversed the liquiritigenin-induced PI3K/AKT pathway inactivation. In conclusion, our research verified that liquiritigenin exerted significant inhibitory effects on CRC invasion and EMT process by down-regulating the expression of Runx2 and inactivating PI3K/AKT signaling pathway. Liquiritigenin could be as an effective therapeutic and prevention medicine for CRC treatment. PMID- 29471889 TI - MiR-365 suppresses cholangiocarcinoma cell proliferation and induces apoptosis by targeting E2F2. AB - Cholangiocarcinoma (CCA) is one of the most malignant adenocarcinoma arising from bile duct epithelial cells. However,the molecular mechanism regulating CCA development and progression requires to be investigated. Here, we found that miR 365 was downregulated in CCA tissues compared with adjacent normal tissues. By functional experiments, we found that overexpression of miR-365 significantly inhibited CCA cell proliferation and promoted cellular apoptosis in vitro. Furthermore, administration with miR-365 markedly suppressed the growth of tumor tissues in vivo. Mechanistically, we identified E2F2 was the target gene of miR 365 in CCA cells. We found that overexpression significantly inhibited the expression of E2F2 in CCA cells. And there was an inversely correlation between the expression levels of E2F2 and miR-365 in CCAtissues. What's more, we found that E2F2 was highly expressed in CCA tissues and cell lines. And restoration of E2F2 in miR-365-overexpressing CCA cells promoted cell viability and reduced cellular apoptosis in CCA. Collectively, our study demonstrated the essential role of miR-365 and its functional mechanism in CCA cells, which provided a new insight on the design of therapeutic targets for CCA treatment. PMID- 29471890 TI - MicroRNA-744 inhibits cellular proliferation and invasion of colorectal cancer by directly targeting oncogene Notch1. AB - Accumulated studies have strongly implicated aberrantly expressed microRNAs (miRNAs) in carcinogenesis and cancer progression of various cancers, including colorectal cancer (CRC). Hence, a comprehensive study of miRNAs and their association with CRC may be a promising therapeutic method for patients with this malignancy. MiRNA-744 (miR-744) is abnormally expressed in several types of human cancer. Thus far, little is known about the expression, biological roles and exact mechanisms of miR-744 in CRC. Thus, the present study measured the expression level of miR-744 and investigated its roles and associated molecular mechanisms in CRC. This study demonstrated that miR-744 expression was significantly underexpressed in CRC tissues and cell lines. Low miR-744 expression was positively associated with lymphatic metastasis and TNM stage. Functional experiments revealed that miR-744 overexpression obviously inhibited the proliferation and invasion of CRC cells. Furthermore, Notch1 was identified as a direct target of miR-744 in CRC. Moreover, the inhibition of Notch1 phenocopied the inhibitory effects of miR-744 overexpression on CRC cells. Restored Notch1 expression markedly rescued the tumour suppressive effects of miR 744 overexpression on CRC cells. Overall, miR-744 exhibits an essential role in CRC progression, and the miR-744/Notch1 axis may provide novel insights into future treatments for patients with CRC. PMID- 29471891 TI - MiR-188-5p suppresses gastric cancer cell proliferation and invasion via targeting ZFP91. AB - MicroRNAs (miRNAs) have been demonstrated to be essential regulators in the development and progression of various cancers. The role of miR-188-5p in gastric cancer has not been determined. In this study, we found that the expression of miR-188-5p was downregulated in gastric cancer (GC) tissues compared with adjacent normal tissues. And lowly expressed miR-188-5p was significantly associated with lymph node metastasis and advanced TNM stage. Moreover, overexpression of miR-188-5p significantly inhibited GC cell proliferation, migration and invasion but promoted cellular apoptosis. In mechanism, we identified transcription factor ZFP91 as a target gene of miR-188-5p in GC. We found that miR-188-5p overexpression significantly inhibited the expression of ZFP91 in GC cell lines. And there was an inversely correlation between the expression of miR-188-5p and ZFP91 in GC tissues. What's more, we found that restoration of ZFP91 in miR-188-5poverexpressed MGC-803 and SGC-7901 cells promoted cell proliferation, migration and invasion. Finally, we also showed that overexpression of miR-188-5p inhibited tumor growth in vivo. Taken together, our findings indicated that miR-188-5p serves as a tumor suppressor in human gastric cancer by targeting ZFP91, suggesting that miR-188-5p might be a promising therapeutic target for GC treatment. PMID- 29471892 TI - MicroRNA-935 inhibits proliferation and invasion of osteosarcoma cells by directly targeting High mobility group box 1. AB - Substantial studies have suggested that microRNAs (miRNAs) are dysregulated in osteosarcoma (OS), which is implicated in OS initiation and progression. Therefore, knowledge of aberrantly expressed miRNAs in OS may provide novel mechanistic insights into the tumorigenesis and tumor development of OS and facilitate therapeutic methods for patients with this aggressive bone neoplasm. In this study, data obtained from reverse transcription-quantitative polymerase chain reaction (RT-qPCR) revealed that miR-935 was significantly decreased in OS tissues and cell lines. Restoration expression of miR-935 obviously restricted proliferation and invasion of OS cells. In addition, high mobility group box 1 (HMGB1) was predicted to be a putative target of miR-935. Subsequent luciferase reporter assay, RT-qPCR and Western blot analysis confirmed that miR-935 could directly target the 3'-untranslated region of HMGB1 and negatively regulated HMGB1 expression in OS cells. Furthermore, a significant negative association was found between miR-935 and HMGB1 mRNA expression in OS tissues. Rescue experiments showed that recovered HMGB1 expression partially rescued miR-935-induced suppression of cell proliferation and invasion in OS. These results provide first evidence for the suppressive roles of miR-935 in OS by directly targeting HMGB1, suggesting that miR-935 may be a potential candidate for the treatment of patients with this disease. PMID- 29471893 TI - MiR-363-3p inhibits osteosarcoma cell proliferation and invasion via targeting SOX4. AB - MiR-363-3p has been proven to suppress tumor growth and metastasis in various human cancers. However, the function of miR-363-3p in osteosarcoma (OS) has not been determined. In our study, we found that the expression of miR-363-3p was significantly downregulated in OS tissues compared with adjacent normal tissues. And miR-363-3p expression was associated with the poor overall survival rate of OS patients. Moreover, we found that overexpression of miR-363-3p markedly inhibited the proliferation, migration and invasion of U2OS and MG63 cells. Moreover, we found that SOX4 was a direct target of miR-363-3p in OS cells. Overexpression of miR-363-3p significantly inhibited the expression of SOX4. And their expression levels were negatively correlated in OS tissues. Finally, we found that restoration of SOX4 attenuated the suppressive effects of miR-363-3p on the proliferation, migration, and invasion of U2OS and MG63 cells. Therefore, our findings demonstrated that miR-363-3p served as a tumor suppressor in OS tissues by targeting SOX4. PMID- 29471894 TI - MiR-615 inhibits prostate cancer cell proliferation and invasion by directly targeting Cyclin D2. AB - Previous studies have reported that miR-615 exerts a tumor suppressor in some tumors, such as esophageal squamous cellcarcinoma and non-small cell lung cancer. However, the role of miR-615 in prostate cancer cells has not been defined. Here, we found that miR-615 was downregulated in prostate cancer tissues and cell lines. And overexpression of miR-615 in PC-3 cells significantly inhibited cellular proliferation, migration and invasion. Moreover, overexpression of miR 615 delayed tumor growth in vivo. In term of mechanism, we found that Cyclin D2 is a target gene of miR-615 in prostate cancer. We showed that miR-615 could bind to the 3?-UTR region of CCND2 mRNA and inhibit its expression. And there was a negatively correlation between the expression of miR-615 and CCND2 in prostate cancer tissues. Moreover, restoration of Cyclin D2 abolished the inhibitory effects of miR-615 on the proliferation, migration and invasion of prostate cancer cells. Taken together, our study identified miR-615 as a tumor suppressor by targeting Cyclin D2 in prostate cancer. PMID- 29471895 TI - ETV6/FLT3 Fusion Is a Novel Client Protein of Hsp90. AB - FMS-like tyrosine kinase-3 fragments from exon 14 to the end without any mutations or deletions have been reported to fuse to ETV6 (TEL) in a few cases of myeloid/lymphoid neoplasms with eosinophilia carrying a translocation t(12;13)(p13;q12). This fusion protein confers constitutive activation on the FLT3 fragment and induces factor-independent growth in transfected Ba/F3 cells, indicating that it is an oncoprotein. However, the mechanism controlling the stability of this oncoprotein is unknown. In this study, we focus on finding factors controlling the stability of ETV6/FLT3. We have shown that the stability of ETV6/FLT3 is regulated by the Hsp90 chaperone. ETV6/FLT3 fusion protein forms a complex with Hsp90 by coimmunoprecipitation analyses using an Hsp90 antibody. The association between ETV6/FLT3 fusion protein and Hsp90 was impaired after treating ETV6/FLT3 transient transfection cos7 cells with 17-allylamino-17 demethoxygeldanamycin (17-AAG). 17-AAG induced a time- and dose-dependent downregulation of ectopically expressed ETV6/FLT3 protein in cos7 and HeLa transfected cells. By using cycloheximide to block new protein translation, we found that 17-AAG accelerated the decay of ETV6/FLT3. Our findings could contribute to more understanding of the ETV6/FLT3 regulation through Hsp90 chaperone and open the way to finding effective treatment strategies for this rare disease.

PMID- 29471899 TI - Principles for constructing a tuberculosis treatment regimen: the role and definition of core and companion drugs. AB - Current World Health Organization guidelines for the formulation of treatment regimens for multidrug-resistant tuberculosis (MDR-TB) pay too little attention to the microbiological activity of anti-tuberculosis drugs. Here, we draw lessons from the pioneering work done on shorter MDR-TB treatment regimens and the current knowledge of the bactericidal and sterilizing properties of the drugs to inform the composition of treatment regimens for MDR-TB. We propose to reserve the term 'core drug' for the one drug in a regimen that contributes most to relapse-free cure. The core drug has both moderate to high bactericidal and sterilizing activity, is given throughout treatment, is well tolerated, and has no cross-resistance with the core drug used in the previous regimen. Currently used core drugs include rifampicin in the first-line 6-month regimen, and fourth generation fluoroquinolones and bedaquiline in regimens for drug-resistant TB. All other drugs are 'companion drugs', used to avert treatment failure due to acquired drug resistance against the core drug. Some also help further reduce the risk of relapse. Moreover, toxic drugs should be avoided if there is an alternative. A regimen must always include the core drug, plus at least one companion drug with high bactericidal activity, a second bactericidal companion drug, plus two sterilizing companion drugs. PMID- 29471900 TI - Prevalence of latent tuberculous infection among adults in the general population of Ca Mau, Viet Nam. AB - SETTING: The study was conducted in a randomly selected sample of persons aged ?15 years living in Ca Mau Province, southern Viet Nam. OBJECTIVE: To estimate the prevalence of latent tuberculous infection (LTBI) in the general adult population of this province of Viet Nam. The secondary objective was to examine age and sex differences in prevalence. DESIGN: A cross-sectional survey was conducted in a cluster-random sample of the population. Clusters were subcommunes. The presence of LTBI was assessed using the QuantiFERON(r)-TB Gold In-Tube test system. RESULTS: QuantiFERON tests were performed among 1319 persons aged ?15 years (77.7% of those selected). The overall prevalence of positive tests was 36.8% (95%CI 33.4-40.3). The prevalence of a positive test was lower in females than in males (31.0% vs. 44.7%, OR 0.57, 95%CI 0.45-0.72, P < 0.0001). The prevalence of positive tests increased with increasing age quintile (P < 0.0001). CONCLUSION: More than one third of the general adult population in a province in southern Viet Nam have evidence of LTBI. Although LTBI prevalence is higher in males, the sex difference is not as great as that for TB notification rates. PMID- 29471901 TI - Investigating a tuberculosis cluster among Filipino health care workers in a low incidence country. AB - SETTING: Nearly 8% of adult tuberculosis (TB) cases in England, Wales and Northern Ireland (EW&NI) occur among health care workers (HCWs), the majority of whom are from high TB incidence countries. OBJECTIVES: To determine if a TB cluster containing multiple HCWs was due to nosocomial transmission. METHODS: A cluster of TB cases notified in EW&NI from 2009 to 2014, with indistinguishable 24-locus mycobacterial interspersed repetitive unit-variable number of tandem repeats (MIRU-VNTR) profiles, was identified through routine national cluster review. Cases were investigated to identify epidemiological links, and occupational health (OH) information was collected for HCW cases. To further discriminate strains, typing of eight additional loci was conducted. RESULTS: Of the 53 cases identified, 22 were HCWs. The majority (n = 43), including 21 HCWs, were born in the Philippines. Additional typing split the cluster into three subclusters and seven unique strains. No epidemiological links were identified beyond one household and a common residential area. HCWs in this cluster received no or inadequate OH assessment. CONCLUSIONS: The MIRU-VNTR profile of this cluster probably reflects common endemic strains circulating in the Philippines, with reactivation occurring in the UK. Furthermore, 32-locus typing showed that 24-locus MIRU-VNTR failed to distinguish strain diversity. The lack of OH assessment indicates that latent tuberculous infection could have been identified and treated, thereby preventing active cases from occurring. PMID- 29471902 TI - Under-reporting of tuberculosis in Praia, Cape Verde, from 2006 to 2012. AB - SETTING: According to World Health Organization (WHO) estimates, the under reporting rate for tuberculosis (TB) in Cape Verde between 2006 and 2012 was 49%. However, the WHO recognises the challenges associated with this estimation process and recommends implementing other methods, such as record linkage, to combat TB under-reporting. OBJECTIVES: To estimate and analyse under-reporting of cases by TB surveillance health units and to evaluate TB cases retrieved from other TB diagnostic sources in Praia, Cape Verde, from 2006 to 2012. DESIGN: This cross-sectional study evaluated under-reporting using the following data: 1) the under-reporting index from TB reporting health units (RHUs), where the number of validated TB cases from RHUs was compared with data from the National Programme for the Fight against Tuberculosis and Leprosy (NPFTL); and 2) the under reporting index among overall data sources, or a comparison of the number of all validated TB cases from all sources with NPFTL data. RESULTS: The TB under reporting rate was 40% in Praia during the study period, and results were influenced by laboratory findings. CONCLUSION: The TB under-reporting rate was very similar to the rate estimated by the WHO. TB surveillance must be improved to reduce under-reporting. PMID- 29471903 TI - Estimating the magnitude of pulmonary tuberculosis patients missed by primary health care clinics in South Africa. AB - SETTING: The present study was conducted at 20 randomly selected primary health clinics across Buffalo City Metropolitan Health District, a high TB burden district in South Africa. OBJECTIVE: To estimate the proportion of TB patients missed by primary health clinics. DESIGN: We enrolled 1255 TB-symptomatic individuals exiting primary health clinics between March and December 2015. Participants were interviewed and asked to provide sputum for Xpert(r) MTB/RIF testing. RESULTS: Clinic staff screened 79.1% of participants seeking care for TB related symptoms and 21.9% of those attending a clinic for other reasons (P < 0.001). Of those screened by clinic staff, 21.5% reported submitting sputum, although only 9.8% had available results. Study staff tested sputum from 779 participants not tested by clinic staff. Of these, 39 (5.0%) individuals tested positive for TB, three of whom were rifampicin-resistant; 15/39 (38.5%) were never screened and 24/39 (61.5%) were screened but not tested by clinic staff. We estimate that the health system missed 62.9-78.5% of TB patients attending primary health clinics for TB-related symptoms and 89.5-100% of those attending a clinic for other reasons. CONCLUSION: Low rates of TB screening and testing by the health system resulted in missed TB patients. Universal TB screening and testing of symptomatic individuals should be instituted in high TB burden communities in South Africa. PMID- 29471904 TI - Completion of isoniazid preventive therapy among human immunodeficiency virus positive adults in urban Malawi. AB - SETTING: Despite worldwide scale-up of human immunodeficiency virus (HIV) care services, relatively few countries have implemented isoniazid preventive therapy (IPT). Among other programmatic concerns, IPT completion tends to be low, especially when not fully integrated into HIV care clinics. OBJECTIVE: To estimate non-completion of 6-month IPT and its predictors among HIV-positive adults aged ?16 years. DESIGN: A prospective cohort study nested within a cluster randomised trial of TB prevention was conducted between February 2012 and June 2014. IPT for 6 months was provided with pyridoxine at study clinics. Non completion was defined as loss to follow-up (LTFU), death, active/presumptive TB or stopping IPT for any other reason. Random-effects logistic regression was used to determine predictors of non-completion. RESULTS: Of 1284 HIV-positive adults initiated on IPT, 885/1280 (69.1%) were female; the median CD4 count was 337 cells/MUl (IQR 199-511); 320 (24.9%) did not complete IPT. After controlling for antiretroviral treatment status, IPT initiation year, age and sex, non-completion of IPT was associated with World Health Organization stage 3/4 (aOR 1.76, 95%CI 1.22-2.55), CD4 count 100-349 cells/MUl (aOR 1.93, 95%CI 1.10-3.38) and any reported side effects (aOR 22.00, 95%CI 9.45-46.71). CONCLUSION: Completion of IPT was suboptimal. Interventions to further improve retention should target immunosuppressed HIV-positive adults and address side effects. PMID- 29471905 TI - Delay in seeking care for tuberculosis symptoms among adults newly diagnosed with HIV in rural Malawi. AB - SETTING: Ten primary health clinics in rural Thyolo District, Malawi. OBJECTIVE: Tuberculosis (TB) is a common initial presentation of human immunodeficiency virus (HIV) infection. We investigated the time from TB symptom onset to HIV diagnosis to describe TB health-seeking behaviour in adults newly diagnosed with HIV. DESIGN: We asked adults (?18 years) about the presence and duration of TB symptoms at the time of receiving a new HIV diagnosis. Associations with delayed health seeking (defined as >30 and >90 days from the onset of TB symptoms) were evaluated using multivariable logistic regression. RESULTS: TB symptoms were reported by 416 of 1265 participants (33%), of whom 36% (150/416) had been symptomatic for >30 days before HIV testing. Most participants (260/416, 63%) were below the poverty line (US$0.41 per household member per day). Patients who first sought care from informal providers had an increased odds of delay of >30 days (adjusted odds ratio [aOR] 1.6, 95%CI 0.9-2.8) or 90 days (aOR 2.0, 95%CI 1.1-3.8). CONCLUSIONS: Delayed health seeking for TB-related symptoms was common. Poverty was ubiquitous, but had no clear relationship to diagnostic delay. HIV positive individuals who first sought care from informal providers were more likely to experience diagnostic delays for TB symptoms. PMID- 29471906 TI - Spatial clustering of drug-resistant tuberculosis in Hlabisa subdistrict, KwaZulu Natal, 2011-2015. AB - SETTING: Incidencerates of tuberculosis (TB) in South Africa are among the highest in the world, and drug resistance is a major concern. Understanding geographic variations in disease may guide targeted interventions. OBJECTIVE: To characterise the spatial distribution of drug-resistant TB (DR-TB) in a rural area of KwaZulu-Natal, South Africa, and to test for clustering. DESIGN: This was a cross-sectional analysis of DR-TB patients managed at a rural district hospital from 2011 to 2015. We mapped all patients in hospital data to local areas, and then linked to a population-based demographic surveillance system to map the patients to individual homesteads. We used kernel density estimation to visualise the distribution of disease and tested for clustering using spatial scan statistics. RESULTS: There were 489 patients with DR-TB in the subdistrict; 111 lived in the smaller demographic surveillance area. Spatial clustering analysis identified a high-risk cluster (relative risk of DR-TB inside vs. outside cluster 3.0, P < 0.001) in the south-east, a region characterised by high population density and a high prevalence of human immunodeficiency virus infection. CONCLUSION: We have demonstrated evidence of a geographic high-risk cluster of DR TB. This suggests that targeting interventions to spatial areas of highest risk, where transmission may be ongoing, could be effective. PMID- 29471907 TI - Multidrug-resistant tuberculosis in Australia, 1998-2012. AB - OBJECTIVE: To describe the epidemiology and outcomes of multidrug-resistant tuberculosis (MDR-TB) diagnosed in Australia between 1998 and 2012. DESIGN: A retrospective review was undertaken involving all patients with laboratory confirmed MDR-TB notified in Australia between 1998 and 2012 inclusive. Demographic, clinical and laboratory features are described. Clinical outcomes were defined according to World Health Organization definitions of treatment success (cure and treatment completion), treatment failure, death, loss to follow up (including transfer out), or not evaluated at treatment completion. RESULTS: A total of 244 cases of MDR-TB were diagnosed in Australia during the study period, representing 1.4% of all TB cases notified. The majority were born outside Australia, including one third in Papua New Guinea. Of those with treatment outcome data available, treatment success was demonstrated in 81%. Treatment success was positively associated with use of a second-line injectable agent. Those born in Papua New Guinea were less likely to achieve treatment success. CONCLUSION: MDR-TB is uncommon in Australia. The large number of cases born in Papua New Guinea, and the poorer outcomes in this cohort, represent challenges with cross-border management of MDR-TB in the Torres Strait. Australia has an ongoing role in the prevention and management of MDR-TB locally and in the region. PMID- 29471908 TI - Prognostic factors for treatment success in patients with multidrug-resistant tuberculosis in China. AB - OBJECTIVE: To examine the clinical outcomes and associated prognostic factors among patients with multidrug-resistant tuberculosis (MDR-TB) in China. METHODS: This retrospective study involved 243 patients with MDR-TB. All patients received standard regimens containing para-amino salicylic acid (PAS) and/or cycloserine (CS). The demographic, social and clinical characteristics of patients were recorded and the patients were followed up for 24 months. RESULTS: Treatment success was closely associated with young age, non-farming occupations, shorter history or smoking, normal urine results, initial MDR-TB treatment regimen, increased haemoglobin, direct bilirubin, uric acid and thyroid stimulating hormone (TSH) levels, and lower white blood cell, neutrophil and blood platelet counts (all P < 0.05). On multivariable analysis, increased haemoglobin (hazard ratio [HR] 1.019, 95%CI 1.007-1.032, P = 0.002) and TSH levels (HR 1.002, 95%CI 1.006-1.039, P = 0.008), normal urine results (HR 1.541, 95%CI 1.008-2.358, P = 0.046) and initial MDR-TB treatment regimen (HR 2.238, 95%CI 1.090-4.597, P = 0.028) were prognostic factors for treatment success in MDR-TB. CONCLUSIONS: Higher haemoglobin and TSH levels, normal urine results and initial MDR-TB treatment regimen might predict successful treatment of MDR-TB. PMID- 29471909 TI - Sputum smear-positive, culture-negative state during anti-tuberculosis treatment in the MGIT liquid culture era. AB - The sputum smear-positive, culture-negative state poses a challenge for clinicians. Previous studies have shown that most samples with positive smears during the later stages of treatment are culture-negative. Earlier studies generally used solid culture media, which tend to be less sensitive than current liquid culture systems. We examined the smear-positive, culture-negative state in the era of MGITTM 960TM liquid cultures. We found that the smear-positive, culture-negative state occurred less frequently with MGIT culture, and that the majority of the samples with late positive smears were culture-negative, regardless of media type. PMID- 29471910 TI - Impact of quality improvement in tuberculosis laboratories in low- and lower middle-income countries: a systematic review. AB - BACKGROUND: The effect of quality improvement measures on the performance of diagnostic tuberculosis (TB) laboratories in low- and lower-middle-income countries is not known, and is the subject of this review. METHODS: Three databases were searched for quality improvement studies presenting data on performance parameters before and after the implementation of quality improvement interventions. RESULTS: Twenty-one studies were included in this review. Quality improvement measures were most frequently implemented by an external organization; settings targeted ranged from microscopy centers, hospitals, districts, regional and national reference laboratories. Quality improvement interventions and outcome measurements were highly heterogeneous. Most studies investigated interventions aimed at improving smear microscopy (n = 17). Two studies evaluated comprehensive quality improvement measures (n = 2) and another three studies focused on mycobacterial culture and drug susceptibility testing. Most studies showed an improvement in outcomes measured on before-after or time trend analysis. CONCLUSION: Quality improvement measures implemented in TB laboratories showed a positive impact on various outcomes. Due to the high heterogeneity of outcome reporting and interventions and the low quality of the studies, the effect size was not clear. Identification of standardized quality indicators and their link to the quality of patient care would improve knowledge in this field. PMID- 29471911 TI - The neuro-endocrine-immune relationship in pulmonary and pleural tuberculosis: a better local profile in pleural fluid. AB - BACKGROUND: Tuberculosis (TB) is a major health problem worldwide. In TB, the immune and central nervous systems modulate each other. The two main components of this network are the hypothalamic-pituitary-adrenal axis (HPA) and autonomic nervous system (ANS). OBJECTIVE: To elucidate neuro-endocrine-immune (NEI) interactions in pulmonary (PTB) or pleural (PLTB) TB, we analysed the relationship among compounds from these systems. METHODS: We quantified levels of catecholamines, hormones and cytokines in plasma from patients with PTB (n = 46) or PLTB (n = 12) and controls (n = 32), and in the pleural fluid from PLTB patients. Transcript expression for genes involved in glucocorticoid-related function (quantitative real-time polymerase chain reaction) was also analysed in mononuclear cells (MCs) from peripheral blood (PBMC) or pleural effusion (PEMC) compartments. RESULTS: Both patient groups had increased plasma levels of pro- and anti-inflammatory cytokines, cortisol, growth hormone (GH) and dopamine, whereas insulin-like growth factor 1 (IGF-1) and dehydroepiandrosterone levels were decreased. The pleural fluid contained increased levels of pro-inflammatory cytokines, GH and IGF-1 and reduced levels of steroid hormones compared with their plasma counterparts. PBMCs from PTB patients had increased expression of transcripts for 11beta-hydroxysteroid dehydrogenase (11betaHSD1) and a decreased glucocorticoid receptor (GR) ratio (GRalpha/GRbeta). In PLTB cases, expression of 11betaHSD1 and GRalpha transcripts was higher in PEMCs. CONCLUSION: PTB patients seem to display adverse NEI dysregulation. Changes in pleural fluid are compatible with a more effective NEI reaction. PMID- 29471912 TI - Detection of tuberculosis patterns in digital photographs of chest X-ray images using Deep Learning: feasibility study. AB - OBJECTIVE: To evaluate the feasibility of Deep Learning-based detection and classification of pathological patterns in a set of digital photographs of chest X-ray (CXR) images of tuberculosis (TB) patients. MATERIALS AND METHODS: In this prospective, observational study, patients with previously diagnosed TB were enrolled. Photographs of their CXRs were taken using a consumer-grade digital still camera. The images were stratified by pathological patterns into classes: cavity, consolidation, effusion, interstitial changes, miliary pattern or normal examination. Image analysis was performed with commercially available Deep Learning software in two steps. Pathological areas were first localised; detected areas were then classified. Detection was assessed using receiver operating characteristics (ROC) analysis, and classification using a confusion matrix. RESULTS: The study cohort was 138 patients with human immunodeficiency virus (HIV) and TB co-infection (median age 34 years, IQR 28-40); 54 patients were female. Localisation of pathological areas was excellent (area under the ROC curve 0.82). The software could perfectly distinguish pleural effusions from intraparenchymal changes. The most frequent misclassifications were consolidations as cavitations, and miliary patterns as interstitial patterns (and vice versa). CONCLUSION: Deep Learning analysis of CXR photographs is a promising tool. Further efforts are needed to build larger, high-quality data sets to achieve better diagnostic performance. PMID- 29471913 TI - A rapid review of treatment literacy materials for tuberculosis patients. AB - OBJECTIVE: To assess available treatment literacy materials for patients undergoing treatment for tuberculosis (TB). DESIGN: We conducted a rapid review by searching the US Centers for Disease Control's Find TB Resources website and the websites of health departments and TB-focused organizations. We included English-language documents intended to educate TB patients about anti tuberculosis treatment. We evaluated the format, readability, and content of documents, and audience. We defined 12 essential content elements based on those previously identified as facilitating human immunodeficiency virus treatment literacy. RESULTS: Of the 205 documents obtained, 45 were included in our review. The median reading grade level was 7 (IQR 5-8). The median number of essential content elements present was 6 (IQR 4-8), with the most comprehensive document containing 11 of the 12 elements. Only two documents were written for children with TB or their care givers, and two for patients with drug-resistant TB. Many documents contained paternalistic and non-patient-centered language. CONCLUSION: We found few examples of comprehensive, patient-centered documents. Work is needed to achieve consensus as to the essential elements of TB treatment literacy and to create additional materials for children, patients with drug-resistant TB, and those with lower literacy levels.

PMID- 29471919 TI - Dupilumab: A review of its use in the treatment of atopic dermatitis. AB - Atopic dermatitis (AD) is a chronic, pruritic immune-mediated inflammatory dermatosis characterized by a T helper 2 (Th2) immune response phenotype and may be associated with systemic inflammation. Dupilumab is an interleukin 4 (IL-4) receptor alpha-antagonist that inhibits IL-4 and IL-13 signaling through blockade of the shared IL-4alpha subunit. Blockade of IL-4/13 is effective in reducing Th2 response. Dupilumab has recently been approved in the United States and Europe for the treatment of adult patients with moderate-to-severe AD. Clinical trials have shown that adults with moderate-to-severe AD who receive weekly or biweekly dupilumab injections have significantly improved clinical and patient-reported outcomes, including Eczema Area Severity Index, SCORing Atopic Dermatitis, Dermatology Life Quality Index, and itch Numeric Rating Scale scores. Concomitant use of topical corticosteroids along with dupilumab results in a greater improvement in signs and symptoms of AD than with use of dupilumab alone. Biomarker analyses show that dupilumab modulates the AD molecular signature and other Th2-associated biomarkers. Common adverse events reported in the clinical trials were nasopharyngitis, upper respiratory tract infection, injection site reactions, skin infections, and conjunctivitis. These were mild-to-moderate in nature, and overall rates of adverse events occurred with similar frequency between the treatment and placebo groups. There were no significant serious safety concerns identified in phase III clinical trials. Dupilumab, as monotherapy or with concomitant use of topical corticosteroids, can significantly improve clinical outcomes and quality of life in patients suffering from moderate to-severe AD. Ongoing studies of dupilumab will help determine the clinical efficacy and safety profile of its long-term use. PMID- 29471921 TI - Concurrent drug injection during opioid agonist treatment among people who inject drugs in Ukraine. AB - Ongoing drug use during opioid agonist treatment (OAT) negatively affects treatment and health outcomes, and increases treatment dropout. This study aimed to examine correlates of concurrent illicit drug use among OAT patients in Ukraine. A random sample of 434 patients currently on OAT receiving buprenorphine (BMT) or methadone maintenance treatment (MMT) from five cities in Ukraine were assessed for factors associated with self-reported concurrent illicit drug use during OAT using a multivariable logistic regression. Among 434 OAT patients, 100 (23%) reported concurrent drug injecting in the previous 30 days; 28% of these were injecting >=20 days. While 100 (100%) of these injected opioids, 24 (24%) injected stimulants; 40 (40%) met criteria for polysubstance use disorder that included opioids, stimulants and alcohol. Independent correlates of concurrent drug injection included: being on MMT vs. BMT (aOR = 2.8, 95%CI = 1.4-5.8), lower OAT dosage (aOR = 1.7, 95%CI = 1.1-2.7), more severe addiction severity (aOR = 2.3, 95%CI = 1.4-3.8), younger age of injection initiation (aOR = 2.3, 95%CI = 1.3-3.9), and presence of alcohol use disorder (aOR = 2.1, 95%CI = 1.3-3.5); participants living with parents were negatively associated with concurrent drug injection. Concurrent drug use was prevalent among OAT patients in Ukraine indicating the urgent needs for tailored interventions and changes in OAT program design and implementation. Results highlight the importance of prescribing an adequate OAT dosage, and discrepancies between MMT and BMT programs in Ukraine addressing needs of OAT patients with specific characteristics such as severe opioid and alcohol dependence. PMID- 29471922 TI - Approach bias modification for cannabis use disorder: A proof-of-principle study. AB - BACKGROUND: More effective treatments for cannabis use disorder (CUD) are needed. Evidence suggests that biases in cognitive processing of drug-related stimuli are central to the development and maintenance of addiction. The current study examined the feasibility and effect of a novel intervention - approach bias modification (ApBM) - on cannabis approach bias and cue-reactivity. METHODS: A randomized, double-blind, sham-controlled proof-of-principle laboratory experiment investigated the effect of a four-session computerized ApBM training protocol on cannabis approach bias and cue-reactivity in non-treatment seeking adults age 18-65 with CUD (N = 33). ApBM procedures involved responding to cannabis or neutral stimuli using a computer joystick to model approach or avoidance behavior. Reactivity to tactile, olfactory, and auditory cue sets was assessed with physiological (blood pressure and heart rate) and subjective (cannabis craving) measures. Cannabis use was assessed via self-report. RESULTS: Participants receiving ApBM showed blunted cannabis cue-induced craving at the end of training compared to those in the sham-ApBM condition (p = .05). A preliminary gender effect on cannabis use was also found; men receiving ApBM reported fewer cannabis use sessions per day at the end of training compared to women (p = .02), while there were no differences between men and women in the sham condition. ApBM did not attenuate cannabis approach bias following training. CONCLUSION: Preliminary results indicate that ApBM may be efficacious in reducing cannabis cue-reactivity and improving cannabis use outcomes. While encouraging, the results should be interpreted with caution. Investigation of ApBM as an adjunct to psychosocial treatments for treatment-seeking adults with CUD is warranted. PMID- 29471923 TI - Integration of Transcendental Meditation(r) (TM) into alcohol use disorder (AUD) treatment. AB - AIMS: Maladaptive responses to stress are thought to play a role in addiction and relapse. Transcendental Meditation (TM) is a popular meditation technique with promising clinical applications. This study sought to: (a) examine the feasibility of providing TM during AUD treatment; (b) compare outcomes for TM vs. treatment as usual (TAU); and (c) investigate the relationship between TM practice and outcomes. METHODS: Meditation-naive adults with primary AUD (N = 60; 35% female, 60% white) newly admitted to inpatient treatment were recruited in sequential cohorts (30 receiving TAU and 30 receiving TM training). Assessments were conducted at baseline and 3-months post-discharge. RESULTS: Integrating TM into inpatient AUD treatment was feasible. Uptake of TM was high (85% meditating on most of the past 30 days at follow-up; 61% closely adherent to recommended practice of twice-daily TM). Participants reported high satisfaction with TM. The sample as a whole improved on multiple measures after AUD treatment, but there were no significant differences between TM and TAU cohorts. However, those practicing TM twice-daily as recommended were less likely than the rest of the sample to return to any drinking (25% vs. 59%; p = .02) or heavy drinking post discharge (0% vs. 47%, p < .001). Greater regularity of TM practice was inversely correlated with stress, psychological distress, craving, and alcohol use at follow-up. CONCLUSIONS: This study established the feasibility and acceptability of using TM during AUD treatment. Consistently practicing TM (but not just learning it) was associated with better outcomes. These promising findings warrant further investigation in larger, controlled studies. PMID- 29471924 TI - Employment after beginning treatment for substance use disorders: The impact of race/ethnicity and client community of residence. AB - Employment is an important substance use treatment outcome, frequently used to assess individual progress during and after treatment. This study examined whether racial/ethnic disparities exist in employment after beginning treatment. It also examined the extent to which characteristics of clients' communities account for such disparities. Analyses are based on data that linked individual treatment information from Washington State's Behavioral Health Administration with employment data from the state's Employment Security Department. Analyses subsequently incorporated community-level data from the U.S. Census Bureau. The sample includes 10,636 adult clients (Whites, 68%; American Indians, 13%, Latinos, 10%; and Blacks, 8%) who had a new outpatient treatment admission to state-funded specialty treatment. Heckman models were used to test whether racial/ethnic disparities existed in the likelihood of post-admission employment, as well as employment duration and wages earned. Results indicated that there were no racial/ethnic disparities in the likelihood of employment in the year following treatment admission. However, compared to White clients, American Indian and Black clients had significantly shorter lengths of employment and Black clients had significantly lower wages. With few exceptions, residential community characteristics were associated with being employed after initiating treatment, but not with maintaining employment or with wages. After accounting for community-level variables, disparities in length of employment and earned wages persisted. These findings highlight the importance of considering the race/ethnicity of a client when examining post-treatment employment alongside community characteristics, and suggest that the effect of race/ethnicity and community characteristics on post-treatment employment may differ based on the stage of the employment process. PMID- 29471925 TI - Cost and cost-effectiveness of computerized vs. in-person motivational interventions in the criminal justice system. AB - INTRODUCTION: Although substance use is common among probationers in the United States, treatment initiation remains an ongoing problem. Among the explanations for low treatment initiation are that probationers are insufficiently motivated to seek treatment, and that probation staff have insufficient training and resources to use evidence-based strategies such as motivational interviewing. A web-based intervention based on motivational enhancement principles may address some of the challenges of initiating treatment but has not been tested to date in probation settings. The current study evaluated the cost-effectiveness of a computerized intervention, Motivational Assessment Program to Initiate Treatment (MAPIT), relative to face-to-face Motivational Interviewing (MI) and supervision as usual (SAU), delivered at the outset of probation. METHODS: The intervention took place in probation departments in two U.S. cities. The baseline sample comprised 316 participants (MAPIT = 104, MI = 103, and SAU = 109), 90% (n = 285) of whom completed the 6-month follow-up. Costs were estimated from study records and time logs kept by interventionists. The effectiveness outcome was self reported initiation into any treatment (formal or informal) within 2 and 6 months of the baseline interview. The cost-effectiveness analysis involved assessing dominance and computing incremental cost-effectiveness ratios and cost effectiveness acceptability curves. Implementation costs were used in the base case of the cost-effectiveness analysis, which excludes both a hypothetical license fee to recoup development costs and startup costs. An intent-to-treat approach was taken. RESULTS: MAPIT cost $79.37 per participant, which was ~$55 lower than the MI cost of $134.27 per participant. Appointment reminders comprised a large proportion of the cost of the MAPIT and MI intervention arms. In the base case, relative to SAU, MAPIT cost $6.70 per percentage point increase in the probability of initiating treatment. If a decision-maker is willing to pay $15 or more to improve the probability of initiating treatment by 1%, estimates suggest she can be 70% confident that MAPIT is good value relative to SAU at the 2-month follow-up and 90% confident that MAPIT is good value at the 6-month follow-up. CONCLUSIONS: Web-based MAPIT may be good value compared to in-person delivered alternatives. This conclusion is qualified because the results are not robust to narrowing the outcome to initiating formal treatment only. Further work should explore ways to improve access to efficacious treatment in probation settings. PMID- 29471926 TI - Do benefits restrictions limit Medicaid acceptance in addiction treatment? Results from a national study. AB - OBJECTIVE: To assess the relationship of restrictions on Medicaid benefits for addiction treatment to Medicaid acceptance among addiction treatment programs. DATA SOURCES: We collected primary data from the 2013-2014 wave of the National Drug Abuse Treatment System Survey. STUDY DESIGN: We created two measures of benefits restrictiveness. In the first, we calculated the number of addiction treatment services covered by each state Medicaid program. In the second, we calculated the total number of utilization controls imposed on each service. Using a mixed-effects logistic regression model, we estimated the relationship between state Medicaid benefit restrictiveness for addiction treatment and adjusted odds of Medicaid acceptance among addiction treatment programs. DATA COLLECTION: Study data come from a nationally-representative sample of 695 addiction treatment programs (85.5% response rate), representatives from Medicaid programs in forty-seven states and the District of Columbia (response rate 92%), and data collected by the American Society for Addiction Medicine. PRINCIPAL FINDINGS: Addiction treatment programs in states with more restrictive Medicaid benefits for addiction treatment had lower odds of accepting Medicaid enrollees (AOR = 0.65; CI = 0.43, 0.97). The predicted probability of Medicaid acceptance was 35.4% in highly restrictive states, 48.3% in moderately restrictive states, and 61.2% in the least restrictive states. CONCLUSIONS: Addiction treatment programs are more likely to accept Medicaid in states with less restrictive benefits for addiction treatment. Program ownership and technological infrastructure also play an important role in increasing Medicaid acceptance. PMID- 29471927 TI - Assessment of the relationship between a written measure of empathy and an independently rated interview of Motivational Interviewing. AB - Motivational Interviewing (MI) is an evidence-based practice shown to be effective when working with people in treatment for substance use disorders. However, MI is a complex treatment modality optimized by training with feedback. Feedback, assessment and monitoring of treatment fidelity require measurement, which is typically done using audiotaped sessions. The gold standard for such measurement of MI skill has been an audiotaped interview, scored by a rater with a detailed structured instrument such as the Motivational Interviewing Treatment Integrity 2.0 (MITI 2.0) Coding System (Moyers, et al., 2005). The Helpful Responses Questionnaire (HRQ) (Miller, Hedrick, & Orlofsky, 1991) is a pen-and paper test of empathy (a foundational MI skill) that does not require an audiotaped session. A randomized trial of three different regimens for training counselors in MI (live supervision using Teleconferencing, Tape-based supervision and Workshop only) (Smith et al., 2012) offered the opportunity to evaluate the performance of the HRQ as a measure of MI ability, compared to the several MITI 2.0 global scores and subscales. Participants were counselors (N=97) working at community-based substance use treatment programs, whose MI proficiency was measured at four time points: baseline (before an initial 2-day MI workshop), post-workshop, 8weeks post-workshop (i.e., post-supervision), and 20weeks post workshop with both MITI 2.0 and HRQ. HRQ total scores correlated significantly with the Reflection to Question Ratio from the MITI 2.0 at post-workshop (r=0.33), week 8 (r=0.34), and week 20 (r=0.38), and with the Spirit (r=0.32) and Empathy (r=0.32) global scores at week 20. Correlations of HRQ with other MITI 2.0 subscales and time points after workshop were small and not significant. As predicted, HRQ scores differed between training conditions (X2(2)=7.88, p=0.02), with counselors assigned to live supervision achieving better HRQ scores than those in Workshop only. In summary, HRQ is a modestly accurate measure, mainly of the Reflection to Question Ratio, considered a core marker of MI skill. It is sensitive to training effects and may help identify counselors needing more intensive supervision. Given its ease of administration and scoring, HRQ may be a useful marker of MI skill during training efforts. PMID- 29471929 TI - Employment services and substance abuse treatment. AB - This qualitative study of over 800 participants focused on the employment experiences of consumers of substance abuse treatment programs to provide a better understanding of what employment services are offered and what needs treatment agencies have in the area of employment services, examining barriers and facilitators from both the consumer and provider perspectives. Data were collected via a mixed research methodology of focus groups and surveys from July 2015 through June 2016 in a large Midwestern U.S. state. Employment is a challenge for persons with substance use disorders. Only a quarter of this study's large sample of substance abuse treatment consumers reported being cur rently employed; and of those consumers who reported no current employment, greater than half reported that their current unemployment was due to their substance use. Persons receiving substance abuse treatment face many challenges in obtaining and maintaining employment. Treatment providers identified several barriers to implementation of employment services. They named an array of resources as needed, including increased funding for supportive employment programs and staff appropriate to the delivery of employment services. Some providers believed employment services to fall outside of their scope of practice. Data generated through this study may inform policy to invest resources in employment services within substance abuse treatment settings. PMID- 29471928 TI - Effects of motivational interviewing fidelity on substance use treatment engagement in primary care. AB - OBJECTIVE: Primary care (PC) may be an opportune setting to engage patients with opioid and alcohol use disorders (OAUDs) in treatment. We examined whether motivational interviewing (MI) fidelity was associated with engagement in primary care-based OAUD treatment in an integrated behavioral health setting. METHODS: We coded 42 first session therapy recordings and examined whether therapist MI global ratings and behavior counts were associated with patient engagement, defined as the patient receiving one shot of extended-release injectable naltrexone or any combination of at least two additional behavioral therapy, sublingual buprenorphine/naloxone prescriptions, or OAUD-related medical visits within 30days of their initial behavioral therapy visit. RESULTS: Autonomy/support global ratings were higher in the non-engaged group (OR=0.28, 95%CI: 0.09-0.93; p=0.037). No other MI fidelity ratings were significantly associated with engagement. CONCLUSION: We did not find positive associations between MI fidelity and engagement in primary care-based OAUD treatment. More research with larger samples is needed to examine how providing autonomy/support to patients who are not ready to change may affect engagement. PRACTICE IMPLICATIONS: Training providers to strategically use MI to reinforce change as opposed to the status quo is needed. This may be especially important in primary care where patients may not be specifically seeking help for their OAUDs. PMID- 29471930 TI - Outcomes of compulsory detention compared to community-based voluntary methadone maintenance treatment in Vietnam. AB - INTRODUCTION: In Vietnam, like many countries in East and Southeast Asia, the government has invested heavily in center-based compulsory treatment (CCT) as the mainstay demand reduction strategy for illicit drug use. This approach has been criticised on human rights grounds. Meanwhile, community-based voluntary methadone maintenance treatment (MMT) has been implemented for nearly a decade with promising results. To date, there have been no comparative Vietnamese studies of these approaches. MATERIAL AND METHODS: The study, involving 208 CCT participants and 384 MMT participants with heroin dependence, was a combined retrospective and prospective observational study conducted over three years between 2012 and 2014 (with data at five time-points). The primary outcome was: self-report heroin use (confirmed by urinalysis). The four secondary outcomes were: illegal behaviours, overdose, blood-borne virus (BBV) risk behaviours, and monthly drug expenditure. Mixed effects regression analyses, which took into account baseline differences between the groups, were used to analyse the data. This study is registered with ClinicalTrials.gov, number NCT03071315. RESULTS: The study found MMT was more strongly associated with four outcome measures compared to CCT (reduction in heroin use (beta = 3.39, SE = 0.31, p < .0001) (equivalent to an odds ratio of 29.67 (95% CI 21.76-40.45)), reduction in illegal behaviours (beta = 0.94, SE = 0.39, p < .0001), (equivalent to an odds ratio of 2.56 (95% CI 1.79-3.78)), reduction in BBV risk behaviours (beta = 1.08, SE = 0.17, p < .0001), (equivalent to an odds ratio of 2.94 (95% CI 2.48-3.49)), and reduction in monthly drug spending (beta = -VND1,515,200 (equivalent to US$72.00), SE = VND452,900, p < .0001)). The analyses did not support the hypothesis that MMT was associated with better outcomes pertaining to overdose (beta = -0.27, SE = 0.30, p = .62), probably due to the infrequency of these self reported events. CONCLUSIONS: Our observational study suggests that MMT is associated with greater reductions in heroin use, BBV risk behaviours, drug related illegal behaviours, and monthly drug spending compared with CCT. In the context that the CCT approach has been criticized for human rights violations, this study provides evidence to support the scale up of MMT and the transition of CCT to voluntary community based treatment. PMID- 29471931 TI - Coronary Artery Bypass Surgery Improves Outcomes in Patients With Diabetes and Left Ventricular Dysfunction. AB - BACKGROUND: The role of percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) in patients with diabetes mellitus (DM) and multivessel coronary artery disease (CAD) has been established by large trials; however, these trials largely excluded patients with left ventricular dysfunction (LVD). OBJECTIVES: The aim of this study was to determine whether treatment with PCI or CABG leads to improved outcomes in patients with DM, CAD, and LVD. METHODS: In this propensity-matched study, outcomes were compared for patients with CAD, DM, and LVD treated with PCI or CABG between 2004 and 2016. The primary outcome was major adverse cardiac and cerebrovascular events, defined as the composite of death, stroke, myocardial infarction, and repeat revascularization. Secondary outcomes were the individual components of the primary outcome. RESULTS: PCI compared with CABG was associated with a higher risk for major adverse cardiac and cerebrovascular events in cohorts with ejection fraction (EF) 35% to 49% (p < 0.001) and <35% (p < 0.001). Treatment with PCI was associated with an increased risk for death in both the EF 35% to 49% and the EF <35% cohorts. Stroke rate did not differ between PCI and CABG in either EF cohort. PCI was associated with an increased rate of MI in the EF <35% cohort, and repeat revascularization occurred more frequently in patients treated with PCI in both the EF 35% to 49% cohort and the EF <35% cohort. CONCLUSIONS: At long-term follow up, patients with CAD, DM, and LVD treated with CABG exhibited a significantly lower incidence of major adverse cardiac and cerebrovascular events and better long-term survival over PCI, without a higher risk for stroke.

PMID- 29471933 TI - Safety and Effectiveness of Second-Generation Drug-Eluting Stents in Patients With Left Main Coronary Artery Disease. AB - BACKGROUND: Limited data are available on the relative performances between different types of drug-eluting stents (DES) for obstructive left main coronary artery disease (LMCAD). OBJECTIVES: This study sought to compare effectiveness and safety profiles of various second-generation DES for LMCAD in real-world clinical practice. METHODS: Among 4,470 patients in 3, multicenter, prospective registries (IRIS-DES [Interventional Cardiology Research Incorporation Society Drug-Eluting Stents] registry, the IRIS-MAIN [Interventional Cardiology Research Incorporation Society-Left MAIN Revascularization] registry, and the PRECOMBAT [PREmier of Randomized COMparison of Bypass Surgery versus AngioplasTy Using Drug Eluting Stent in Patients with Left Main Coronary Artery Disease] study) treated between July 2007 and July 2015, the authors identified 2,692 patients with significant LMCAD who received second-generation DES; 1,254 with cobalt-chromium everolimus-eluting stents (CoCr-EES), 232 with biodegradable polymer biolimus eluting stents (BP-BES), 616 with platinum-chromium EES (PtCr-EES), and 590 with Resolute zotarolimus-eluting stent (Re-ZES). The primary outcome was target vessel failure. RESULTS: The observed 3-year rates of target-vessel failure were not significantly different for the different types of DES (16.7% for the CoCr EES, 13.2% for the BP-BES, 18.7% for the PtCr-EES, and 14.7% for the Re-ZES; p = 0.15). In multiple treatment propensity score analysis, the adjusted hazard ratios (HRs) for target-vessel failure were similar in between-group comparisons of the different DES, except for the PtCr-EES versus the BP-BES (reference; HR: 1.60; 95% confidence interval: 1.01 to 2.54; p = 0.046). There were no significant differences in risk of composite of all-cause death, any myocardial infarction, or any revascularization and its individual components according to the different types of DES. Although the 3-year incidence of stent thrombosis was considerably low (<=1.0%) for all types of DES, between-group differences were observed, generally favoring the EES platforms. CONCLUSIONS: In this pooled analysis of 3 prospective registries involving unrestricted use of various second generation DES for LMCAD, we found no significant between-group differences in 3 year risk of target-vessel failure, except for a higher risk of primary outcome with PtCr-EES compared to BP-BES.

PMID- 29471935 TI - Multivessel Percutaneous Coronary Intervention in Patients With ST-Segment Elevation Myocardial Infarction With Cardiogenic Shock. AB - BACKGROUND: Recent trials demonstrated a benefit of multivessel percutaneous coronary intervention (PCI) for noninfarct-related artery (non-IRA) stenosis over IRA-only PCI in patients with ST-segment elevation myocardial infarction (STEMI) multivessel disease. However, evidence is limited in patients with cardiogenic shock. OBJECTIVES: This study investigated the prognostic impact of multivessel PCI in patients with STEMI multivessel disease presenting with cardiogenic shock, using the nationwide, multicenter, prospective KAMIR-NIH (Korea Acute Myocardial Infarction-National Institutes of Health) registry. METHODS: Among 13,104 consecutive patients enrolled in the KAMIR-NIH registry, we selected patients with STEMI with multivessel disease presenting with cardiogenic shock and who underwent primary PCI. Primary outcome was 1-year all-cause death, and secondary outcomes included patient-oriented composite outcome (a composite of all-cause death, any myocardial infarction, and any repeat revascularization) and its individual components. RESULTS: A total of 659 patients were treated by multivessel PCI (n = 260) or IRA-only PCI (n = 399) strategy. The risk of all cause death and non-IRA repeat revascularization was significantly lower in the multivessel PCI group than in the IRA-only PCI group (21.3% vs. 31.7%; hazard ratio: 0.59; 95% confidence interval: 0.43 to 0.82; p = 0.001; and 6.7% vs. 8.2%; hazard ratio: 0.39; 95% confidence interval: 0.17 to 0.90; p = 0.028, respectively). Results were consistent after multivariable regression, propensity score matching, and inverse probability weighting to adjust for baseline differences. In a multivariable model, multivessel PCI was independently associated with reduced risk of 1-year all-cause death and patient-oriented composite outcome. CONCLUSIONS: Of patients with STEMI and multivessel disease with cardiogenic shock, multivessel PCI was associated with a significantly lower risk of all-cause death and non-IRA repeat revascularization. Our data suggest that multivessel PCI for complete revascularization is a reasonable strategy to improve outcomes in patients with STEMI with cardiogenic shock.

PMID- 29471938 TI - Revisiting Reverse Remodeling After Aortic Valve Replacement for Aortic Stenosis. PMID- 29471937 TI - Reverse Myocardial Remodeling Following Valve Replacement in Patients With Aortic Stenosis. AB - BACKGROUND: Left ventricular (LV) hypertrophy, a key process in human cardiac disease, results from cellular (hypertrophy) and extracellular matrix expansion (interstitial fibrosis). OBJECTIVES: This study sought to investigate whether human myocardial interstitial fibrosis in aortic stenosis (AS) is plastic and can regress. METHODS: Patients with symptomatic, severe AS (n = 181; aortic valve area index 0.4 +/- 0.1 cm2/m2) were assessed pre-aortic valve replacement (AVR) by echocardiography (AS severity, diastology), cardiovascular magnetic resonance (CMR) (for volumes, function, and focal or diffuse fibrosis), biomarkers (N terminal pro-B-type natriuretic peptide and high-sensitivity troponin T), and the 6-min walk test. CMR was used to measure the extracellular volume fraction (ECV), thereby deriving matrix volume (LV mass * ECV) and cell volume (LV mass * [1 - ECV]). Biopsy excluded occult bystander disease. Assessment was repeated at 1 year post-AVR. RESULTS: At 1 year post-AVR in 116 pacemaker-free survivors (age 70 +/- 10 years; 54% male), mean valve gradient had improved (48 +/- 16 mm Hg to 12 +/- 6 mm Hg; p < 0.001), and indexed LV mass had regressed by 19% (88 +/- 26 g/m2 to 71 +/- 19 g/m2; p < 0.001). Focal fibrosis by CMR late gadolinium enhancement did not change, but ECV increased (28.2 +/- 2.9% to 29.9 +/- 4.0%; p < 0.001): this was the result of a 16% reduction in matrix volume (25 +/- 9 ml/m2 to 21 +/- 7 ml/m2; p < 0.001) but a proportionally greater 22% reduction in cell volume (64 +/- 18 ml/m2 to 50 +/- 13 ml/m2; p < 0.001). These changes were accompanied by improvement in diastolic function, N-terminal pro-B-type natriuretic peptide, 6-min walk test results, and New York Heart Association functional class. CONCLUSIONS: Post-AVR, focal fibrosis does not resolve, but diffuse fibrosis and myocardial cellular hypertrophy regress. Regression is accompanied by structural and functional improvements suggesting that human diffuse fibrosis is plastic, measurable by CMR and a potential therapeutic target.

PMID- 29471939 TI - Tet2-Mediated Clonal Hematopoiesis Accelerates Heart Failure Through a Mechanism Involving the IL-1beta/NLRP3 Inflammasome. AB - BACKGROUND: Recent studies have shown that hematopoietic stem cells can undergo clonal expansion secondary to somatic mutations in leukemia-related genes, thus leading to an age-dependent accumulation of mutant leukocytes in the blood. This somatic mutation-related clonal hematopoiesis is common in healthy older individuals, but it has been associated with an increased incidence of future cardiovascular disease. The epigenetic regulator TET2 is frequently mutated in blood cells of individuals exhibiting clonal hematopoiesis. OBJECTIVES: This study investigated whether Tet2 mutations within hematopoietic cells can contribute to heart failure in 2 models of cardiac injury. METHODS: Heart failure was induced in mice by pressure overload, achieved by transverse aortic constriction or chronic ischemia induced by the permanent ligation of the left anterior descending artery. Competitive bone marrow transplantation strategies with Tet2-deficient cells were used to mimic TET2 mutation-driven clonal hematopoiesis. Alternatively, Tet2 was specifically ablated in myeloid cells using Cre recombinase expressed from the LysM promoter. RESULTS: In both experimental heart failure models, hematopoietic or myeloid Tet2 deficiency worsened cardiac remodeling and function, in parallel with increased interleukin 1beta (IL-1beta) expression. Treatment with a selective NLRP3 inflammasome inhibitor protected against the development of heart failure and eliminated the differences in cardiac parameters between Tet2-deficient and wild-type mice. CONCLUSIONS: Tet2 deficiency in hematopoietic cells is associated with greater cardiac dysfunction in murine models of heart failure as a result of elevated IL 1beta signaling. These data suggest that individuals with TET2-mediated clonal hematopoiesis may be at greater risk of developing heart failure and respond better to IL-1beta-NLRP3 inflammasome inhibition.

AB - OBJECTIVES: This study sought to compare the appropriate use and outcomes of percutaneous coronary intervention (PCI) between top-ranked and nonranked hospitals. BACKGROUND: The U.S. News & World Report "Best Hospitals" rankings are an influential consumer-directed publication of hospital quality, and are commonly used in promotional campaigns by hospital systems. METHODS: Hospitals in the National Cardiovascular Data Registry CathPCI registry between July 1, 2014, and June 30, 2015, were classified as top-ranked if they were included in the 2015 U.S. News & World Report 50 best "Cardiology and Heart Surgery" hospitals. The remaining were classified as nonranked. We compared in-hospital mortality, post-procedural bleeding, post-procedural acute kidney injury, and the proportion of appropriate PCI procedures between top-ranked and nonranked hospitals. RESULTS: A total of 509,153 PCIs at 654 hospitals were included, of which 55,550 (10.9%) were performed at 44 top-ranked hospitals. After adjusting for patient case mix, PCIs performed at top-ranked hospitals had similar odds of in-hospital mortality (adjusted odds ratio [aOR]: 0.96; 95% confidence interval [CI]: 0.83 to 1.12; p = 0.64), acute kidney injury (aOR: 1.10; 95% CI: 0.98 to 1.22; p = 0.099), and bleeding (aOR: 1.15; 95% CI: 0.99 to 1.31; p = 0.052). Top-ranked hospitals had a slightly lower proportion of appropriate PCI compared with nonranked hospitals (89.2% vs. 92.8%; OR: 0.56; 95% CI: 0.45 to 0.69; p < 0.001). CONCLUSIONS: PCI performed at top-ranked hospitals was not associated with superior outcomes compared with PCI at nonranked hospitals. The inclusion of metrics based on clinical data may be important for hospital quality rankings.

PMID- 29471949 TI - Impact of Routine Invasive Physiology at Time of Angiography in Patients With Multivessel Coronary Artery Disease on Reclassification of Revascularization Strategy: Results From the DEFINE REAL Study. AB - OBJECTIVES: This study sought to prospectively assess the impact of routine invasive physiology at the time of angiography on reclassification of therapeutic management of multivessel disease (MVD) patients, and to assess how implementation of instantaneous wave-free ratio (iFR) alters the process. BACKGROUND: Routine invasive physiology in intermediate coronary lesions at the time of diagnostic angiography, primarily in patients with single-vessel disease and using fractional flow reserve (FFR), reclassifies coronary revascularization management in 26% to 44% of patients. The role of invasive physiology in patients with MVD is unclear. METHODS: In 18 centers, 484 patients undergoing diagnostic angiography disclosing MVD with lesions >40% by visual assessment were included. Investigators were asked to prospectively define their initial management strategy based on angiography and clinical information. Invasive physiology (FFR or iFR driven) was then performed and final strategy defined. Initial and final vessel, patient, procedural, and overall management were described. Reclassification was defined as the difference between initial and final strategy. RESULTS: The majority of patients were clinically stable (82.2%). Two- and 3-vessel disease was present in 73.3% and 26.7% of patients, respectively. Lesions investigated were "intermediate" with median percent stenosis, median FFR, and median iFR at 60% (interquartile range [IQR]: 50% to 70%), 0.84 (IQR: 0.78 to 0.90), and 0.92 (IQR: 0.85 to 0.96), respectively. Vessel management was reclassified by physiology in 30.0% (249 of 828) of vessels. Patient and overall management were reclassified in 26.9% (130 of 484) and 45.7% (211 of 484) of patients, respectively. Reclassification rates were high irrespective of initial management (optimal medical therapy, percutaneous coronary intervention, or coronary artery bypass grafting), and performance and results of pre-procedural noninvasive tests. Reclassification of overall management in particular increased with the number of vessels investigated (1 vessel: 37.3%; 2 vessels: 45.0%; 3 vessels: 66.7%; p = 0.002). Incorporating iFR in the decision process was associated with investigation of more vessels (p = 0.04) and higher reclassification (p = 0.0001). CONCLUSIONS: In patients with MVD and intermediate coronary lesions, invasive physiology at time of angiography reclassifies revascularization strategy in a large proportion of cases (26.9%) and investigation of more vessels is associated with higher reclassification rates.

AB - OBJECTIVES: The study sought to characterize patient- and hospital-level variation in early angiography use among non-ST-segment elevation myocardial infarction (NSTEMI) patients. BACKGROUND: Contemporary implementation of guideline recommendations for early angiography use in NSTEMI patients in the United States have not been described. METHODS: The study analyzed NSTEMI patients included in ACTION (Acute Coronary Treatment and Intervention Outcomes Network) registry (2012 to 2014) who underwent in-hospital angiography. Timing of angiography was categorized as early (<=24 h) vs. delayed (>24 h). The study evaluated factors associated with early angiography, hospital-level variation in early angiography use, and the relationship with quality-of-care measures. RESULTS: A total of 79,760 of 138,688 (57.5%) patients underwent early angiography. Factors most strongly associated with delayed angiography included weekend or holiday presentation, lower initial troponin ratio values, higher initial creatinine values, heart failure on presentation, and older age. Median hospital-level use of early angiography was 58.5% with wide variation across hospitals (21.7% to 100.0%). Patient characteristics did not differ substantially across hospitals grouped by tertiles of early angiography use (low, middle, and high). Hospitals in the highest tertile tended to more commonly use guideline recommended medications and had higher defect-free care quality scores. CONCLUSIONS: In contemporary U.S. practice, high-risk clinical characteristics were associated with lower use of early angiography in NSTEMI patients; hospital level use of early angiography varied widely despite few differences in case mix. Hospitals that most commonly utilized early angiography also had higher quality of-care metrics, highlighting the need for improved NSTEMI guideline adherence.

PMID- 29471953 TI - Improvement of Risk Prediction After Transcatheter Aortic Valve Replacement by Combining Frailty With Conventional Risk Scores. AB - OBJECTIVES: This study sought to evaluate whether frailty improves mortality prediction in combination with the conventional scores. BACKGROUND: European System for Cardiac Operative Risk Evaluation (EuroSCORE) or Society of Thoracic Surgeons (STS) score have not been evaluated in combined models with frailty for mortality prediction after transcatheter aortic valve replacement (TAVR). METHODS: This prospective cohort comprised 330 consecutive TAVR patients >=70 years of age. Conventional scores and a frailty index (based on assessment of cognition, mobility, nutrition, and activities of daily living) were evaluated to predict 1-year all-cause mortality using Cox proportional hazards regression (providing hazard ratios [HRs] with confidence intervals [CIs]) and measures of test performance (providing likelihood ratio [LR] chi-square test statistic and C statistic [CS]). RESULTS: All risk scores were predictive of the outcome (EuroSCORE, HR: 1.90 [95% CI: 1.45 to 2.48], LR chi-square test statistic 19.29, C-statistic 0.67; STS score, HR: 1.51 [95% CI: 1.21 to 1.88], LR chi-square test statistic 11.05, C-statistic 0.64; frailty index, HR: 3.29 [95% CI: 1.98 to 5.47], LR chi-square test statistic 22.28, C-statistic 0.66). A combination of the frailty index with either EuroSCORE (LR chi-square test statistic 38.27, C statistic 0.72) or STS score (LR chi-square test statistic 28.71, C-statistic 0.68) improved mortality prediction. The frailty index accounted for 58.2% and 77.6% of the predictive information in the combined model with EuroSCORE and STS score, respectively. Net reclassification improvement and integrated discrimination improvement confirmed that the added frailty index improved risk prediction. CONCLUSIONS: This is the first study showing that the assessment of frailty significantly enhances prediction of 1-year mortality after TAVR in combined risk models with conventional risk scores and relevantly contributes to this improvement.

AB - INTRODUCTION: Although autosomal dominant polycystic kidney disease is the most common hereditary kidney disease, available data tend to be limited to after initiation of renal replacement therapy. OBJECTIVE: To ascertain an overview of autosomal dominant polycystic kidney disease within the health area of Granada in southern Spain. MATERIAL AND METHODS: From January 2007 to December 2016, we collected clinical, family and demographic information about all patients with autosomal dominant polycystic kidney disease, irrespective of whether or not they were treated with RRT, in the Granada health area. The computer software SPSS 15.0 and GenoPro were used. RESULTS: 50.6% of the 1,107 diagnosed patients were men. 99.1% were Caucasian and 4-6 generations/family were studied. The geographical distribution was heterogeneous. There was no family history in 2.43%. The mean age of diagnosis was 34.0+/-17.80 years and the diagnosis was made after having offspring in 57.7% of cases. The main reason for diagnosis was family history (46.4%). The mean age of initiation of renal replacement therapy was 54.2+/-11.05 years. 96.3% of the deceased had some degree of renal failure at the time of death. The mean age of death was 60.9+/-14.10 years, the main cause of death being unknown in 33.5% of cases, followed by cardiovascular (27.8%). CONCLUSIONS: Cases and families were concentrated in certain geographical areas and a significant number of individuals were undiagnosed prior to cardiovascular death or diagnosed late after reproduction. Given that there is currently no curative treatment, the primary prevention strategy of preimplantation genetic diagnosis should play a leading role.

PMID- 29471963 TI - [Hepatotoxicity of tyrosine kinase inhibitors: Mechanisms involved and practical implications]. AB - Tyrosine kinase inhibitors (TKIs) are used for the targeted treatment of solid cancers. TKIs produce a variable incidence of liver adverse events (5-25%) which can progress to severe liver injury in a minority of patients if treatment is maintained despite ongoing injury. This risk requires careful patient management to maintain treatment benefit without harm. This review highlights the various mechanisms of idiosyncratic hepatotoxicity, the formation of reactive metabolites and how this leads to toxicity. These critical events depend of the drug-specific characteristics of each TKI and the patient risk factors, especially genetic characterization. With improved understanding of the mechanisms leading to hepatotoxicity, several strategies have been adopted to prevent or treat this side effect. Recommendations on liver function liver test monitoring have been proposed according to each TKI. PMID- 29471964 TI - Use of integrative services is associated with maintenance of work schedule during and after cancer treatment. AB - INTRODUCTION: Cancer diagnosis affects employment status. Our health network offers supportive services to cancer patients. We hypothesized patients who used these services were more likely to continue to work during and after treatment. METHODS: A mailed survey was used to assess employment before, during, and after treatment, and support services used. Chi-square analysis was performed. RESULTS: The response rate was 34% (273/782). 87% of patients worked full or part time before cancer diagnosis, 68.8% continued to work during treatment, and 73.9% returned to work after treatment. 61% of patients used at least one type of support service. Patients who had no change in work status during treatment and who returned to work less than one month after treatment were more likely to use services. CONCLUSIONS: Most patients used support services, continued to work during treatment, and returned to pre-cancer employment status. Physicians should encourage patients to pursue supportive therapies. PMID- 29471965 TI - Early experience with a combined surgical and obstetrics/gynecology clerkship: We do get along. AB - BACKGROUND: In 2012, the Ohio State University College of Medicine (OSUCOM) implemented a new undergraduate medical curriculum. We compare outcomes of a third year traditional clerkship format to a combined Surgery and Obstetrics/Gynecology 'ring'. METHODS: Performance outcomes of 4 consecutive classes were compared between pre- (2014, 2015) and post-curricular revision (2016, 2017). RESULTS: Three hundred ninety-one students consented use of their educational data for research. We examined medical knowledge (NBME scores, USMLE Step 1 and Step 2 CK scores) and student satisfaction between pre- and post curricular revision. Results demonstrated no statistically significant difference in the Obstetrics/Gynecology NBME shelf examination. Surgery NBME and USMLE Step 2 scores were increased and statistically significant but satisfaction of both disciplines was higher pre-curricular revision. CONCLUSION: Medical knowledge outcomes in this combined 'ring' were similar to or higher than performance in previous years'. Future analyses are needed to assess the impact of OSUCOM curricular revision. PMID- 29471966 TI - Oral health management considerations for patients with sickle cell disease.

AB - Considering the performances of conventional Kalman filter may seriously degrade when it suffers stochastic faults and unknown input, which is very common in engineering problems, a new type of adaptive three-stage extended Kalman filter (AThSEKF) is proposed to solve state and fault estimation in nonlinear discrete time system under these conditions. The three-stage UV transformation and adaptive forgetting factor are introduced for derivation, and by comparing with the adaptive augmented state extended Kalman filter, it is proven to be uniformly asymptotically stable. Furthermore, the adaptive three-stage extended Kalman filter is applied to a two-dimensional radar tracking scenario to illustrate the effect, and the performance is compared with that of conventional three stage extended Kalman filter (ThSEKF) and the adaptive two-stage extended Kalman filter (ATEKF). The results show that the adaptive three-stage extended Kalman filter is more effective than these two filters when facing the nonlinear discrete-time systems with information of unknown inputs not perfectly known.

AB - This paper investigates the problems of stability and stabilization for a networked control system (NCS) with additive time-varying delay components' controller. Firstly, stability of a NCS with additive time-varying delays is investigated. A novel approach with free parameters is proposed. By constructing a new Lyapunov-Krasovskii functional (LKF) with two free parameters, stability criteria are obtained. The obtained stability criteria depend not only on upper bounds of delays but also free parameters. In addition, input-output method is extended to study the stability problem for the NCS. Compared with other approaches such as input-output method, the free-parameter approach is more flexible and effective in reducing the conservatism. Then, based on the stability results, a state feedback controller is designed to guarantee the asymptotically stable of the closed-loop systems. Finally, numerical examples are provided to show the effectiveness and less conservatism of the proposed results. PMID- 29471970 TI - The accuracy and precision of Kilovoltage Intrafraction Monitoring (KIM) six degree-of-freedom prostate motion measurements during patient treatments. AB - BACKGROUND AND PURPOSE: To perform a quantitative analysis of the accuracy and precision of Kilovoltage Intrafraction Monitoring (KIM) six degree-of-freedom (6DoF) prostate motion measurements during treatments. MATERIAL AND METHODS: Real time 6DoF prostate motion was acquired using KIM for 14 prostate cancer patients (377 fractions). KIM outputs the 6DoF prostate motion, combining 3D translation and 3D rotational motion information relative to its planning position. The corresponding groundtruth target motion was obtained post-treatment based on kV/MV triangulation. The accuracy and precision of the 6DoF KIM motion estimates were calculated as the mean and standard deviation differences compared with the ground-truth. RESULTS: The accuracy +/- precision of real-time 6DoF KIM-measured prostate motion were 0.2 +/- 1.3 degrees for rotations and 0.1 +/- 0.5 mm for translations, respectively. The magnitude of KIM-measured motion was well correlated with the magnitude of ground-truth motion resulting in Pearson correlation coefficients of >=0.88 in all DoF. CONCLUSIONS: The results demonstrate that KIM is capable of providing the real-time 6DoF prostate target motion during patient treatments with an accuracy +/- precision of within 0.2 +/- 1.3 degrees and 0.1 +/- 0.5 mm for rotation and translation, respectively. As KIM only requires a single X-ray imager, which is available on most modern cancer radiotherapy devices, there is potential for widespread adoption of this technology. PMID- 29471971 TI - Towards the Integration of Niche and Network Theories. AB - The quest for understanding how species interactions modulate diversity has progressed by theoretical and empirical advances following niche and network theories. Yet, niche studies have been limited to describe coexistence within tropic levels despite incorporating information about multi-trophic interactions. Network approaches could address this limitation, but they have ignored the structure of species interactions within trophic levels. Here we call for the integration of niche and network theories to reach new frontiers of knowledge exploring how interactions within and across trophic levels promote species coexistence. This integration is possible due to the strong parallelisms in the historical development, ecological concepts, and associated mathematical tools of both theories. We provide a guideline to integrate this framework with observational and experimental studies.

AB - Wastewater reclamation now represents an effective measure for sustainable water resource management in arid regions, however wastewater components (organic micropollutants) may potentially impact local ecological and/or human health. Previous studies have shown that sodium bentonite/natural clay (BC) mixes may be used to effectively reduce riverbed infiltration in regions characterized by excessively high hydraulic conductivity. Accordingly, the current study sought to investigate the contaminant removal efficiency (Re) of several BC mass ratios in simulated dry riverbeds. Results indicate that the measured Re of NH4+-N, CODcr and BOD5 increased in concurrence with an increasing sodium bentonite ratio, up to a maximum Re of 97.4% (NH4+-N), 55.2% (CODcr), and 51.5% (BOD5). The primary contaminant removal site was shown to be the infiltration-reducing (BC) layer, accounting for approximately 40%, 60%, and 70% of NH4+-N, CODcr and BOD5 removal, respectively. Conversely, the removal efficiency of NO3-N was found to be low (<15%), while total phosphorous (TP) was found to actively leach from the infiltration-reduction layer, resulting in measured TP discharges 2.4-4.8 times those of initial infiltration values. The current study provides a technical baseline for the efficacy of sodium bentonite as an effective bi-functional material in areas utilizing reclaimed water i.e. concurrent reduction of infiltration rates (Function 1) and decontamination of reclaimed wastewater infiltration/recharge (Function 2). Findings indicate that sodium bentonite-clay mixes may represent a feasible alternative for managing recharge of non-potable aquifers with reclaimed wastewater.

AB - The objective of this study was to determine the effects that parity may have on production, reproduction and the metabolic status of Holstein cows managed in a production system based on total mixed ration and pasture. Primiparous (n = 22) and multiparous (n = 24) cows from a dairy farm research station in Uruguay were used in a completely randomized design. Body weight (BW), body condition score (BCS) and backfat thickness (BFT) were recorded weekly from -30 to 70 days postpartum. Milk production was measured daily, and milk composition was determined weekly. Resumption of postpartum ovarian activity and progesterone profiles were measured three times a week based on milk progesterone. Blood was collected to determine the levels of glucose, insulin-like growth factor I (IGF 1), insulin, non-esterified fatty acids (NEFA), beta-hydroxybutyrate (BHB), albumin, total protein and cholesterol. Milk production and components were lower for primiparous cows (p < 0.01) than multiparous cows. Body weights were also lower in primiparous cows than in multiparous cows (p < 0.05); however, BCS and BFT were greater (p < 0.01) in primiparous cows than in multiparous cows. Primiparous cows had greater levels of glucose, insulin and IGF-1 and lower concentrations of NEFA and BHB (p < 0.01) than multiparous cows. The intervals from calving to first ovulation were not affected by parity; however, primiparous cows showed less abnormal cycles (27.2%) than multiparous cows (50.0%) (p < 0.01). The present study found that a feeding system based on TMR and pasture was sufficient to produce over 25 L of milk per day without extending their calving to first ovulation interval in primiparous and multiparous cows. However, multiparous cows showed a greater imbalance in metabolic and hormonal profiles than primiparous cows, causing abnormal ovarian activity. PMID- 29471978 TI - Generalization and maintenance of functional communication training for individuals with developmental disabilities: A systematic and quality review. AB - BACKGROUND: Functional communication training (FCT) is considered an evidence based practice for treating problem behavior in individuals with developmental disabilities (e.g. autism, intellectual disabilities, down syndrome, etc.). However, there is little known on how to sustain behavioral change following FCT interventions. This systematic and quality review synthesizes the current literature base evaluating the maintenance and generalization of behavioral effects following FCT. METHOD: A systematic review identified 37 studies that met the pre-set inclusion criteria. Those studies were summarized in terms of: (a) generalization dimension, (b) generalization assessment design, (c) maintenance assessment design, (d) maintenance and generalization teaching strategy, and (e) latency to maintenance probes. All studies employed single-case research designs and were evaluated using the What Works Clearinghouse pilot single-case research standards (Kratochwill et al., 2013) as adapted by Maggin, Briesch, and Chafouleas (2013). Maintenance and generalization data were evaluated using a researcher-developed rubric based on the WWC standards. RESULTS AND DISCUSSION: Results indicate that 30 studies met standards or met standards with reservations while only six studies also met all of the maintenance and generalization standards. Of the six studies, five did not implement any additional strategies beyond the contacting natural contingencies that is inherent in the FCT intervention. Implications for future research and practice are discussed.

AB - OBJECTIVE: To study the influence of the presentation of results of a preventive medical examination on risk perception and willingness to seek help for work related fatigue or being overweight. METHODS: A factorial design experiment was conducted, presenting workers (n = 82) with vignettes including eight scenarios of test results with and without an emphasis on the risk of a current or future health condition or a probe to seek help. Participants rated perceived risk and willingness to seek help (0-100 Visual Analogue Scale) as if these were their own results. Differences were tested with paired-sample t-tests. RESULTS: In scenarios emphasizing the risk of a current or future disorder, participants perceived higher risk and were more willing to seek help (p-values < .00). Slightly higher willingness to seek help scores was observed in all scenarios that included probes (p < .00). CONCLUSION: Risk perception and willingness to seek help of workers participating in a preventive medical examination were higher when they were told that the test results indicate a risk of a current or future disorder and after being advised to seek help. PRACTICE IMPLICATIONS: Healthcare providers should take the potential effects on risk perception and help-seeking into account in preventive settings.

AB - The purpose of this review was to describe methodologic considerations in using the National Survey of Children With Special Health Care Needs (NS-CSHCN) for transition research in terms of variable inclusion and definition of transition outcomes and to provide suggestions for using NS-CSHCN for transition research. A systematic review was conducted. Inclusion criteria included use of NS-CSHCN data and transition as an outcome variable. Fourteen studies were included. Ten (71%) studies evaluated a sample of all CSHCN. Ten (71%) articles used all four variables recommended by the Maternal and Child Health Bureau core outcome on transition. Other variables included patient-centered medical home. The NS-CSHCN provides a rich dataset that can be used in transition research addressing transition preparation from the parent perspective. Using the NS-CSHCN, we recommend analyzing all variables related to the Maternal and Child Health Bureau core outcome for transition, variables related to patient-centered medical home, and further analysis of specific health conditions.

AB - The Play Nicely program is a multimedia training program designed to teach caregivers and health care professionals how to manage early childhood aggression and to use positive parenting practices. The aim of this article is to help the practicing clinician determine whether the Play Nicely program should be incorporated into his/her practice and to evaluate whether the program is effective at decreasing positive attitudes toward spanking in a socioeconomically disadvantaged population in both a resident pediatric clinic and a community center. Thirty-three caregivers of children aged 2 to 5 years viewed the Play Nicely program and completed pre- and post-training questionnaires. Decreased positive attitudes toward spanking were reported after training. Favorable attitudes toward spanking were associated with increased use of harsher discipline and higher child externalizing behavior. This study provides support that this brief intervention is effective in a socioeconomically disadvantaged population, is portable, and can be used in a group setting. This program may serve as a prevention and population-based approach to addressing the adverse childhood experience of spanking. PMID- 29471983 TI - Current Trends in Methylotrophy. AB - Methylotrophy is a field of study dealing with microorganisms capable of utilization of compounds devoid of carbon-carbon bonds (C1 compounds). In this review, we highlight several emerging trends in methylotrophy. First, we discuss the significance of the recent discovery of lanthanide-dependent alcohol dehydrogenases for understanding both the occurrence and the distribution of methylotrophy functions among bacteria, and then we discuss the newly appreciated role of lanthanides in biology. Next, we describe the detection of other methylotrophy pathways across novel bacterial taxa and insights into the evolution of methylotrophy. Further, data are presented on the occurrence and activity of aerobic methylotrophs in hypoxic and anoxic environments, questioning the prior assumptions on niche separation of aerobic and anaerobic methylotrophy. The concept of communal function in aerobic methane oxidation is also briefly discussed. Finally, we review recent research in engineering methylotrophs for biotechnological applications as well as recent progress in engineering synthetic methylotrophy.

PMID- 29471987 TI - Unique contributions of Keraleeya Ayurveda in pediatric health care. AB - Childhood is considered as the most important phase in life, which determines the quality of health, well being, learning and behaviour across the lifespan. This may be the reason for giving the foremost position for Balacikitsa among Ashtangas (8 branches) of Ayurveda. The regional growth of indigenous medicine gave significant contribution for the development of primary health care. Kerala has major contribution of many authentic textbooks of Balacikitsa like Arogyakalpadruma, Vaidya Tarakam etc. These are more practically oriented and it can be considered as a physician's quick reference hand book. Many new diseases which are not mentioned in classical textbooks have found their place in these books. Medications like Praakaara yoga, Uramarunnuprayoga were administered in children as a mode of immunization, which helps in the maintenance of health and prevention of disease. Many diseases like Karappan (balavisarpa), Shakarogas etc. were common in Kerala and various indigenous treatment modalities were developed for such diseases. Single drug Prayogas with herbs like Mayaphal (galls), Tripadi (DesmodiumTriflorum L.), etc. and yogams like Nalikerakwatha (Putapakakalpana), Mukkuti (Takrakalpana) etc. were practiced commonly. Many effective therapies like Shashtikapindasweda, Thalapothichil (Sirolepa) etc. are an inevitable part of Balacikitsa. In this paper, an attempt is made to compile the theoretical concepts and unique practices of Balacikitsa in Kerala and to convey it's importance. The present article also addresses, how these vernacular books and traditional knowledge waned away from the Mainstream Ayurveda. PMID- 29471988 TI - Multicenter, Randomized Trial of Conventional Balloon Angioplasty versus Paclitaxel-Coated Balloon Angioplasty for the Treatment of Dysfunctioning Autologous Dialysis Fistulae. AB - PURPOSE: To investigate the potential added value of paclitaxel-coated balloon (PCB) angioplasty to reduce fistula dysfunction related to recurrent stenoses in patients undergoing hemodialysis. MATERIALS AND METHODS: A prospective, randomized study was conducted in 3 dialysis referral centers. From January 2013 to October 2015, 64 patients (22 female, 42 male) with dysfunctional autologous dialysis fistulae were randomized to undergo conventional percutaneous balloon angioplasty (n = 31) or PCB angioplasty (n = 33). Procedural and postprocedural data were assessed. Primary patency of the fistula was evaluated at 3, 6, and 12 months following the procedure. Statistical analysis was based on the Fisher exact test and independent t test. RESULTS: There were no procedural or postprocedural complications. After 3, 6, and 12 months of follow-up, primary patency rates after PCB angioplasty and percutaneous transluminal angioplasty (PTA) were 88% and 80% (P = .43), 67% and 65% (P = .76), and 42% and 39% (P = .95), respectively. CONCLUSIONS: Although primary patency rates after PCB angioplasty in autologous dialysis fistulae at 3, 6, and 12 months of follow-up are slightly better than those after PTA, the difference is not statistically significant. PMID- 29471989 TI - The Relationship Between Intradialytic Nutrition and Gastrointestinal Symptoms Using a Modified Version of the Gastrointestinal Symptom Rating Scale. AB - OBJECTIVE: Intradialytic nutrition has been shown to improve nutritional status in maintenance hemodialysis (HD) patients but remains controversial due in part to concerns over hemodynamic stability and gastrointestinal (GI) distress. There are limited data on the relationship between intradialytic nutrition and GI symptoms, possibly due to the lack of a validated tool. Therefore, we intended to validate a questionnaire to measure GI symptoms associated with a single HD treatment and determine the relationship between intradialytic nutrition and GI symptoms. DESIGN: Cross-sectional study. Forty-eight maintenance HD patients. MAIN OUTCOME MEASURE: GI symptoms and dietary intake during HD treatment. RESULTS: In general, we found acceptable internal consistency (Cronbach's alpha >0.5, exception reflux domain) and repeatability in all 5 domains of a modified version of the Gastrointestinal Symptom Rating Scale. The prevalence of GI symptoms associated with a single HD treatment (generalized score greater than 1) was 54.2, 43.7, 6.2, 41.7, and 45.8% for the abdominal pain, indigestion, reflux, diarrhea, and constipation domains, respectively. More than two-thirds of patients chose to eat during treatment (168.6 +/- 165.6 kcal) with the most commonly consumed items being candy, oral supplements, and cookies. There was no difference in GI symptoms among patients who did or did not eat (P > .05). However, the amount of total dietary fat and fiber consumed during treatment was associated with greater indigestion (P < .05) prior to accounting for outliers or multiple comparisons. CONCLUSION: In this sample, the modified version of the Gastrointestinal Symptom Rating Scale was a generally valid tool for measuring GI symptoms associated with a single HD treatment. Patients who ate during treatment did not experience greater GI symptoms than those who did not; however, high amounts of fat and fiber may be associated with greater GI symptoms. Prospective trials should examine the relationship between GI symptoms and dietary intake during treatment in HD patients.

AB - Divinyl-132,173-cyclopheophorbide-a enol was in vivo produced as a metabolite of divinyl-chlorophyll-a by protists and in vitro prepared by the intramolecular cyclization of methyl divinyl-pyropheophorbide-a, one of the divinyl-chlorophyll a derivatives. The 1H NMR spectra in CDCl3 showed that the obtained product took exclusively its enol form in the solution. The intramolecular cyclization of chlorin pi-system at the C132 and C173 positions affected the optical properties of such chlorophyll derivatives including the non-fluorescent emission of the enol.

AB - Interventional radiology is a constantly evolving specialty overlapping with multiple other specialties, including cardiology, vascular surgery, orthopedic surgery, urology, and minimally invasive surgery. Unique ergonomic considerations for interventional radiology include utilization of intraoperative viewing monitors and personal radiation protection equipment. Work-related injuries are common in interventional radiologists,1 often leading to pain while performing procedures or during time away from work. This review article aims to identify the ergonomic challenges related to interventional radiology and provide background, guidelines, and specific recommendations for prevention of musculoskeletal injury. PMID- 29471995 TI - Should We Keep the Lead in the Aprons? AB - Medical staff should not be exposed to the primary X-ray beam during fluoroscopy guided interventional procedures (FGIP). The main source of staff exposure is scatter radiation from the patient, which can be significant. Although many aspects of X-ray exposure to the patient as well as occupational exposure to interventional radiologists and other staff are strongly regulated and monitored in most countries, it is surprising how loosely the labeling and testing of the protective aprons is regulated. Interventional radiologists (IRs) have to be experts in interventional radiology as well as in basic facts regarding ways to provide a satisfactory level of protection from occupational exposure. IRs, however, are not familiar with the apron testing methods. The accompanying documents provided with aprons by manufacturers may not be informative enough. Vendors often report apron effectiveness at a single beam quality and attenuation. The vendor reports repeatedly disagree with independent reports, which clearly show that the attenuation of these garments at other important unreported energies may be lower than expected. Better trust no one and check your protective garment yourself, or, better yet, consult a medical physicist when making purchasing decisions related to protective garments. Each interventionist should choose garments that are appropriately protective for that individual's practice. Review of past personal dosimetry results and consultation with a medical physicist can help the IR make the best decision. This article will help the reader to understand why all protective garments are not created equally, and provides some practical tools that will allow safe and healthy practice in FGIP. PMID- 29471996 TI - The Eyes Have It. AB - The ocular lens is one of the most susceptible structures in the body to radiation damage. Unfortunately, much of the traditional academic and regulatory thinking on thresholds to develop radiation-induced opacities or cataracts has proven to be false. Individual vulnerability to the effects of radiation is extremely variable, largely because each individual is variably genetically equipped to repair the damage caused by radiation. Therefore many people, including some unsuspecting interventional radiologists may have no, or almost no, threshold at all for cataract development after radiation injury. For most others, if there is a threshold it is a fraction of what was previously thought. These new data have become apparent during the same time period when unprecedented numbers of physicians and medical staff have been exposed to unprecedented doses of scatter radiation as the number and complexity of fluoroscopic guided procedures has exploded. Increased rates of radiation lens damage have already been documented in physicians and support staff working in interventional medicine. As there is a latency period of years to decades for lens injury to fully evolve it is quite possible the true incidence will not be known for some time. Strategies to minimize the potential risks encountered in interventional medicine include radiation safety best practices, passive and personal barrier protection, and philosophical approach to interventional radiology practice. Ignore this article at your peril. PMID- 29471997 TI - Always on My Mind. AB - This article is focused on occupational radiogenic brain tumors and some radioprotective techniques used to manage this risk. Published case reports have stimulated concern among operators. The anatomical pattern of tumor locations is not consistent with measured radiation dose distributions at operators' heads. In addition, the lack of statistically positive findings in these reports, and a recently published survey on radiologist's mortality both indicate that the current level of fluoroscopists' radiation safety practices is likely to be adequate. This presumes that the rules of dose-management, time, distance, and shielding continue to be followed. These are briefly reviewed in this article. The use of radioprotective surgical caps is a current fashion. In clinical practice, these caps provide minimal reductions in brain dose and might induce operators to neglect applying the practical rules mentioned above. Appropriate management of personal, staff, and patient risk should always be on the radiologists' mind. PMID- 29471998 TI - Baby on Board: Managing Occupational Radiation Exposure During Pregnancy. AB - This article reviews the issue of occupational radiation exposure as a deterrent to recruitment of women into the field of interventional radiology and provides the reader with three strategies to optimize radiation protection during fluoroscopically guided procedures. These include personal protective shielding, use of ancillary shielding, and techniques that limit fluoroscopy x-ray tube output. When optimal radiation safety practices are implemented as the norm in the IR suite, very little extra needs to be done to ensure that fetal dose of a pregnant interventionalist is negligible. PMID- 29471999 TI - Make Radiation Protection a Habit. AB - This review describes the basic concepts and methods for optimization of occupational dose in the interventional suite. In fluoroscopy, the source of virtually all radiation exposure to the operator is scattered radiation from the patient. All other things being equal, reducing patient radiation dose will reduce operator and staff dose. Most tools and methods of occupational radiation protection are entirely operator dependent. These methods must be used routinely and properly to be effective. Your occupational dose depends on how well you follow good radiation protection practices and on the kinds of procedures you do. The only way to know your own occupational dose is to wear your dosimeters for every case. If proper protection practices are followed and appropriate protection tools are used, annual effective dose for an interventionalist should be well below 10mSv/y, and will more likely be in the range of 2-4mSv/y. However, if proper protection practices and tools are not used, annual effective doses may be much higher. You should review your own doses periodically. PMID- 29472000 TI - Get the Lead off Our Backs! AB - Many interventionalists face physical challenges almost daily for years or decades. The burden of assuming awkward positions while carrying extra weight can take its toll on the musculoskeletal system to such an extent that the career is ended or modified to exclude procedural aspects. The proliferation of lighter aprons has unfortunately resulted in reduced protection with poor correlation of protection to labeling due to the inadequacies of testing methods for nonlead materials. The protective quality of the non-leads is not superior to lead containing composites on a weight basis, and the user no longer knows how well they are protected unless buying aprons containing lead. Various useful methods and shields that may reduce radiation exposure are supported by the floor, ceiling, table, or patient. The suspended personal radiation protection system is a recent development which provides substantially greater radiation protection than conventional lead aprons combined with other shields, while also taking all of the weight off of the operator. It is composed of an expansive and thick (1mm Pb equiv) apron with a large face-shield to protect the neck, head, and eyes, and is suspended overhead to provide motion in the x, y, and z planes. Exposures may also be substantially reduced by leaving the area during acquisition sequences and use of power injectors. PMID- 29472001 TI - MACRA 2018 and the Virtual Group. PMID- 29472002 TI - Role of orexins in the central and peripheral regulation of glucose homeostasis: Evidences & mechanisms. AB - Orexins (A & B), neuropeptides of hypothalamic origin, act through G-protein coupled receptors, orexin 1 receptor (OX1R) and orexin 2 receptor (OX2R). The wide projection of orexin neurons in the hypothalamic region allows them to interact with the other neurons and regulate food intake, emotional status, sleep wake cycle and energy metabolism. The autonomic nervous system plays an important regulatory role in the energy metabolism as well as glucose homeostasis. Orexin neurons are also under the control of GABAergic neurons. Emerging preclinical as well as clinical research has reported the role of orexins in the glucose homeostasis since orexins are involved in hypothalamic metabolism circuitry and also rely on sensing peripheral metabolic signals such as gut, adipose derived and pancreatic peptides. Apart from the hypothalamic origin, integration and control in various physiological functions, peripheral origin in wide organs, raises the possibility of use of orexins as a therapeutic biomarker in the management of metabolic disorders. The present review focuses the central as well as peripheral roles of orexins in the glucose homeostasis.

AB - Patients with previous atherosclerotic cardiovascular disease (ASCVD) and/or heterozygous familial hypercholesterolemia (HeFH) are at high risk of future cardiovascular events. Despite maximally tolerated doses of statins, many patients still have elevated low-density lipoprotein cholesterol (LDL-C) levels. We evaluated the efficacy and safety of alirocumab in patients with ASCVD and/or HeFH on a maximally tolerated dose of statin (rosuvastatin 20 or 40 mg, atorvastatin 40 or 80 mg, or simvastatin 80 mg, or lower doses with an investigator-approved reason) +/- other lipid-lowering therapies from 5 placebo controlled phase 3 trials (52 to 78 weeks). Patients with (n = 2,449) and without (n = 1,050) ASCVD were pooled from the FH I, FH II, HIGH FH, LONG TERM, and COMBO I trials. Patients with HeFH with (n = 575) and without ASCVD (n = 682) were pooled from all trials except COMBO I. High-intensity statins were utilized in 55.7% to 59.0% and in 72.4% to 87.6% of the ASCVD and the HeFH groups, respectively. Efficacy end points included LDL-C percent change from baseline to week 24 stratified by alirocumab dose. Mean baseline demographics and lipid levels were comparable in alirocumab- and placebo-treated patients. LDL-C reductions from baseline at week 24 ranged from 46.6% to 51.3% for alirocumab 75/150 mg and from 54.1% to 61.9% for alirocumab 150 mg in ASCVD and HeFH groups and were sustained for up to 78 weeks. LDL-C reductions with alirocumab were independent of ASCVD and/or HeFH status (interaction p value >0.05). Concordant results were observed for other lipids analyzed. The overall safety in the subgroups analyzed was similar in both treatment arms. Injection-site reactions were observed more frequently with alirocumab versus placebo. PMID- 29472009 TI - Long-Term Change in Cardiorespiratory Fitness in Relation to Atrial Fibrillation and Heart Failure (from the Kuopio Ischemic Heart Disease Risk Factor Study). AB - The benefits of aerobic fitness in relation to all-cause and cardiovascular mortality is well established; however, the associations of long-term change in cardiorespiratory fitness (CRF) with incident heart failure (HF) and atrial fibrillation (AF) have not been studied before. The Kuopio Ischaemic Heart Disease Risk Factor Study is a prospective cohort comprising men aged 42 to 60 years from the city of Kuopio and its surroundings, with a baseline examination between 1984 and 1989 (V1), a re-examination at 11 years (V2), and up to 15 years of follow-up from V2. CRF, as assessed by VO2max, was measured at both visits using respiratory gas exchange during maximal exercise tolerance test. The difference (DeltaVO2max) was estimated as VO2max (V2) - VO2max (V1). Participants with no missing data on both baseline and 11-year exercise test were included (n = 481). The mean DeltaVO2max was -5.4 ml/min?kg (standard deviation 5.4). During a median follow-up of 14.3 years (interquartile range 13.3 to 15.1), 46 incident HF (9.6%) and 73 incident AF (15.2%) events were recorded. In a multivariate analysis adjusted for baseline age, baseline VO2max, systolic blood pressure, smoking, type 2 diabetes, and cardiovascular disease, per 1 ml/min?kg higher DeltaVO2max was log linearly associated with incident HF with a 10% relative risk reduction of HF (hazard ratio 0.90, 95% confidence interval 0.83 to 0.97). No significant relation of DeltaVO2max with incident AF was observed. In conclusion, overall long-term improvement in CRF is associated with reduced risk of HF, indicating the importance of maintaining good CRF over time. PMID- 29472010 TI - A little bit faster: Lower extremity joint kinematics and kinetics as recreational runners achieve faster speeds. AB - There appears a linear relationship between small increases in running speed and cardiovascular health benefits. Encouraging or coaching recreational runners to increase their running speed to derive these health benefits might be more effective if their joint level kinematic and kinetic strategy was understood. The aim of this investigation was to compare the peak sagittal plane motions, moments, and powers of the hip, knee and ankle at 85%, 100%, 115% and 130% of self-selected running speed. Overground running data were collected in 12 recreational runners (6 women, 6 men) with a full body marker set using a 12 camera Vicon MX system with an AMTI force plate. Kinematics and kinetics were analyzed with Vicon Nexus software. Participants chose to run at 2.6 +/- 0.5 m/s (85%); 3.0 +/- 0.5 m/s (100%); 3.3 +/- 0.5 m/s (115%); and 3.7 +/- 0.5 m/s (130%); these four speeds approximately correspond to 6:24-, 5:33-, 5:03-, and 4:30-min kilometer running paces. Running speed had a significant effect (P < 0.05) on peak kinematic and kinetic variables of the hips, knees and ankles, with peak sagittal hip moments invariant (P > 0.54) and the peak sagittal ankle power generation (P < 0.0001) the most highly responsive variable. The timing of the peak sagittal extensor moments and powers at the hip, knee and ankle were distributed across stance in a sequential manner. This study shows that running speed affects lower limb joint kinematics and kinetics and suggests that specific intersegmental kinetic strategies might exist across the narrow range of running speeds. PMID- 29472011 TI - Chemokine regulation of innate lymphoid cell tissue distribution and function. AB - Three groups of innate lymphoid cells (ILCs) can be defined based on transcription factor requirements, cytokine production profiles, and roles in immunity. Given their strategic anatomical location into barrier tissues and the ability to rapidly produce cytokines and to cross-talk with other immune and non immune cells, ILCs play fundamental functions in tissue homeostasis and regulation of immune responses. Several members of the chemokine family influence ILC tissue localization in the correct microenvironment by regulating their release from the bone marrow as well as their homing and retention in the tissues. In this review, we discuss the recent advances on how chemokine regulation of ILC tissue-positioning and functional interaction with other cells play essential roles in tissue-specific regulation of innate and adaptive immune responses. PMID- 29472012 TI - Prioritising recommendations to advance community pharmacy practice. AB - INTRODUCTION: The nature of community pharmacy in many countries has changed. Despite the significant efforts made to change practice, there is a paucity of literature that highlights consensus on the approaches that should be prioritised for advancing practice particularly in the context of developing countries. OBJECTIVE: To systematically identify and prioritise a range of potential recommendations to improve practice in Indonesian community pharmacy from the perspective of pharmacy stakeholders. METHODS: Qualitative research using Nominal Group Technique (NGT) was conducted in July 2017 involving 34 nationwide pharmacy stakeholders. Participants were assigned to four nominal group discussions based on the areas for action as developed by researchers. The results were thematically analysed. RESULTS: Nine priority recommendations were generated from the group discussion reflecting four main themes to advance community pharmacy sector, namely improving professional pharmacy practice, reforming pharmacy education, enforcing policy and regulation and enhancing public recognition of pharmacists. The analysis using the culture-structure-agency approach highlights that the top down structure in terms of policy and regulatory framework has not been effectively enforced. In addition, the role of pharmacists as the central agency in delivering pharmacy services has been limited due to their common absence from practice. The approach, however, provides an alternative to advocate changes by locating the role of pharmacists and community pharmacy as central agency within the challenging health system structure. CONCLUSIONS: The recommendations generated from and approach used in this study provide an impetus to advance community pharmacy practice in Indonesia. Amongst the important solutions, there is substantial need to provide evidence of pharmacists' contribution to healthcare. PMID- 29472013 TI - Using Technology in Global Otolaryngology. AB - Technology is integral to the diverse diagnostics and interventions of Otolaryngology. Historically, major advances in this field derive from advances of associated technologies. Challenges of visualization and surgical access are increasingly overcome by integrating endoscopic, electronic, and robotic instruments. Otolaryngology is often limited to urban areas and large academic centers, making it difficult to allocate care and resources to many underserved populations. The widespread use of technology has important implications in regards to global access to this field as telemedicine is most effectively applied to specialties that are heavily reliant on data and visuals that may be electronically disseminated. PMID- 29472014 TI - Imaging diagnosis of portal hypertension. AB - Portal hypertension is a clinical entity defined by a hydrostatic pressure greater than 5mm Hg in the portal territory, being clinically significant when it is greater than or equal to 10mm Hg. Starting from this threshold, complications can develop, such as the bleeding of esophageal varices, the appearance of ascites, or hepatic encephalopathy. Imaging techniques play an important role as a noninvasive method for determining whether portal hypertension is present. This article analyzes various imaging findings that can suggest the presence of portal hypertension and can help to define its etiology, severity, and possible complications. PMID- 29472015 TI - [What is the cost of treatment of diabetic retinopathy by argon laser in Yaounde?] AB - PURPOSE: To evaluate the total cost of treatment of diabetic retinopathy by argon laser for a patient when indicated. PATIENTS AND METHOD: Prospective cross sectional and descriptive survey, carried out in the angiography and laser center of the Yaounde Central Hospital from October 2014 to October 2015. All consecutive diabetic patients with retinopathy and suitable indication for argon laser treatment were included. The costs related to the initial and final fluorescein angiography, the appointment for follow-up, round-trip transportation costs from the patient's home and the cost of laser treatment were included. RESULTS: Included were 43 (13 %) patients out of 330 with diabetic retinopathy. The mean age was 55.67+/-8.40years. There were 25 women (58.1 %) and 18 men (41.9 %) for a M/F ratio of 0.7. Unemployed patients were represented by 28 (65.1 %) versus 15 employed (34.9 %). Twenty-seven patients (62.8 %) were self-pay for all their expenses, 14 (32.6 %) were assisted by their families, and 2 (4.6 %) were insured. On average, the total expenditure was 86002+/-67197 f CFA per eye, corresponding to 131+/-102 euros with an exchange rate of 1 euro for 656 f CFA. CONCLUSION: The cost of treatment of diabetic retinopathy by argon laser is high, mostly increased by the additional costs related to transportation in our area. The creation of satellite centers in the 10 regions of Cameroon would reduce these costs.

AB - As the only oncologists that provide both medical and surgical oncologic care, gynecologic oncologists encounter an exceptionally broad range of indications for prescribing opioids, from management of acute post-operative pain to chronic cancer-related pain to end-of-life care. If we are to balance opioid efficacy, safety and accessibility for our patients, we must be intimately familiar with appropriate clinical use of opioids in a range of settings, and engage in the national conversation around opioid misuse and how associated regulations and legislation may impact us and our patients. This article examines the appropriate use of opioids across the range of clinical settings encountered in gynecologic oncology.

AB - OBJECTIVE: To evaluate serum levels of the amino-terminal propeptide of C-type natriuretic peptide (NTproCNP) in uneventful pregnancies and pregnancies complicated by preeclampsia (PE) and NTproCNP's accuracy for prediction of PE. STUDY DESIGN: Nested case control pilot study including women with uneventful pregnancy (Control, n = 100) and asymptomatic women who later developed PE (PE_long, n = 12). NTproCNP levels were measured in a maximum of ten sequential blood samples per patient (seven visits during pregnancy, three afterwards), which had been collected prospectively. RESULTS: In controls, NTproCNP decreased from weeks 11-13 on, reaching a nadir at the end of the second trimester (weeks 23-27), and subsequently reached the highest levels at the end of pregnancy. In comparison, the PE_long group showed a significantly different NTproCNP course (p = .042), including significantly elevated levels in weeks 18-22 (p = .034) and 23 27 (p = .016). Significant predictive power of single time point measurements of NTproCNP for predicting short-term occurrence of preeclampsia in asymptomatic women was found in weeks 28-32 (p = .023) and 33-36 (p = .014). Furthermore, an increase > -0.038 pmol/l per week between weeks 11-13 and 14-17 was also predictive for PE (area under the curve, AUC: 0.75; p < .001; sensitivity: 90%; specificity: 60%), as was an increase of > 0.084 pmol/l per week between weeks 11 13 and 18-22 (AUC: 0.69, p = .048; sensitivity: 55%; specificity: 88%). CONCLUSIONS: Measurement of NTproCNP in pregnancy might be useful to increase diagnostic awareness in women who will develop PE. PMID- 29472018 TI - Tuberculosis control interventions targeted to previously treated people in a high-incidence setting: a modelling study. AB - BACKGROUND: In high-incidence settings, recurrent disease among previously treated individuals contributes substantially to the burden of incident and prevalent tuberculosis. The extent to which interventions targeted to this high risk group can improve tuberculosis control has not been established. We aimed to project the population-level effect of control interventions targeted to individuals with a history of previous tuberculosis treatment in a high-incidence setting. METHODS: We developed a transmission-dynamic model of tuberculosis and HIV in a high-incidence setting with a population of roughly 40 000 people in suburban Cape Town, South Africa. The model was calibrated to data describing local demography, TB and HIV prevalence, TB case notifications and treatment outcomes using a Bayesian calibration approach. We projected the effect of annual targeted active case finding in all individuals who had previously completed tuberculosis treatment and targeted active case finding combined with lifelong secondary isoniazid preventive therapy. We estimated the effect of these targeted interventions on local tuberculosis incidence, prevalence, and mortality over a 10 year period (2016-25). FINDINGS: We projected that, under current control efforts in this setting, the tuberculosis epidemic will remain in slow decline for at least the next decade. Additional interventions targeted to previously treated people could greatly accelerate these declines. We projected that annual targeted active case finding combined with secondary isoniazid preventive therapy in those who previously completed tuberculosis treatment would avert 40% (95% uncertainty interval [UI] 21-56) of incident tuberculosis cases and 41% (16-55) of tuberculosis deaths occurring between 2016 and 2025. INTERPRETATION: In this high-incidence setting, the use of targeted active case finding in combination with secondary isoniazid preventive therapy in previously treated individuals could accelerate decreases in tuberculosis morbidity and mortality. Studies to measure cost and resource implications are needed to establish the feasibility of this type of targeted approach for improving tuberculosis control in settings with high tuberculosis and HIV prevalence.

AB - BACKGROUND: Spinal angiolipomas are rare epidural tumours that are usually revealed by chronic symptoms of medullar irritation. We report a case of acute paraplegia caused by spontaneous bleeding revealing a thoracic angiolipoma. CASE DESCRIPTION: A 17-year-old male patient with no previous medical history was admitted for acute onset of paraplegia with bladder retention and loss of sensation in the lower limbs, preceded by dorsal pain during the three previous days. MRI showed an enhanced T1-weighted image of a T7-T12 epidural lesion. The T1-weighted isosignal and the T2-weighted hyposignal suggested haemorrhagic complications. Due to a mass effect on the spinal cord, an emergency laminectomy was performed. Histopathological examination of the lesion revealed an angiolipoma with spontaneous bleeding. Clinical outcome was favourable after two months. CONCLUSION: This case is one of the first to be reported, although the clinical presentation is similar to that of other rare reported cases of paraplegia due to spinal compression by tumoural bleeding. PMID- 29472021 TI - Burnout Syndrome: Global Medicine Volunteering as a Possible Treatment Strategy. AB - BACKGROUND: In the last few decades, "burnout syndrome" has become more common among clinicians, or at least more frequently recognized. Methods to prevent and treat burnout have had inconsistent results. Simultaneously, clinicians' interest in global medicine has increased dramatically, offering a possible intervention strategy for burnout while providing help to underserved areas. DISCUSSION: Caused by a variety of stressors, burnout syndrome ultimately results in physicians feeling that their work no longer embodies why they entered the medical field. This attitude harms clinicians, their patients and colleagues, and society. Few consistently successful interventions exist. At the same time, clinicians' interest in global medicine has risen exponentially. This paper reviews the basics of both phenomena and posits that global medicine experiences, although greatly assisting target populations, also may offer a strategy for combating burnout by reconnecting physicians with their love of the profession. CONCLUSIONS: Because studies have shown that regular volunteering improves mental health, short-term global medicine experiences may reinvigorate and reengage clinicians on the verge of, or suffering from, persistent burnout syndrome. Fortuitously, this intervention often will greatly benefit medically underserved populations. PMID- 29472022 TI - Is food protein induced enterocolitis syndrome only a non IgE-mediated food allergy? AB - Food protein induced enterocolitis syndrome (FPIES) is classified as non-IgE mediated or cell-mediated food allergy, although there is an atypical phenotype so defined for the presence of specific IgEs. All diagnostic criteria for FPIES include the absence of skin or respiratory symptoms of IgE-mediated type. We present four cases that suggest that specific IgEs may have a pathogenic role, resulting in the existence of different FPIES phenotypes. This could be important from a diagnostic and therapeutic point of view. PMID- 29472023 TI - First Patient With Salla Disease Confirmed by Genomic Analysis in Japan. PMID- 29472024 TI - Evaluation of the relationship between ventricular end-diastolic pressure and echocardiographic measures of diastolic function in adults with a Fontan circulation. AB - BACKGROUND: Echocardiographic assessment of diastolic function in the setting of Fontan physiology is not well validated. We recently demonstrated that atrioventricular systolic to diastolic duration ratio (AVV S/D ratio) independently predicts mortality in Fontan-adults and that a value >1.1 was associated with poor prognosis. PURPOSE: To correlate echocardiographic measures of diastolic function with direct measurement of ventricular end-diastolic pressure (VEDP). METHODS: A retrospective analysis was undertaken of Fontan adults who had transthoracic echocardiography (TTE) within 12 months of direct measurement of VEDP during cardiac catheterisation. RESULTS: Fifteen Fontan adults (3 males, mean age 29 +/- 9 years) were evaluated. Thirteen patients had dominant morphologic left ventricle and 2 had morphologic right ventricle. Four had atriopulmonary connection and 11 had total cavopulmonary connection. Twelve patients were NYHA Class I/II and 3 were Class III. Time between TTE and cardiac catheter was 46 +/- 113 days; VEDP was 8 +/- 5 mmHg. Ten patients had preserved ventricular function, 3 had mild and 2 had moderate systolic impairment by subjective TTE assessment. AVV S/D ratio had the strongest correlation with VEDP (r = 0.8, p = 0.001). AVV S/D ratio >= 1.1 had 100% positive predictive value and 92% negative predictive value for detecting VEDP >10 mmHg. The only conventional echocardiographic measure of diastolic function that correlated with VEDP was pulmonary vein A wave - atrioventricular A wave duration difference (r = 0.8, p = 0.02). CONCLUSIONS: TTE measures reflect VEDP in adults with a Fontan circulation. AVV S/D ratio is a simple parameter yet to enter standard practice that can be used to identify elevated VEDP. PMID- 29472025 TI - Aortic stenosis and aortic regurgitation express different titin isoforms: Differences and relationships with functional and geometric characteristics. AB - Background-Titin represents an important biomechanical sensor which determines compliance and diastolic/systolic function of the left ventricle (LV). To assess the different titin-isoform expression and the relationships with functional and geometric patterns, we analyzed titin-isoform expression and cardiomyocytes contractile function in myocardial biopsy samples of patients undergoing aortic valve replacement (AVR) for aortic stenosis (AS) and for aortic regurgitation (AR). Method -Specimens, collected from the LV of 35 with AS and 35 with AR undergoing AVR were analyzed for titin-isoform expression and cardiomyocytes force measurement. Ten donor hearts were analyzed as controls for normal values. Results were implemented with preoperative geometry and function assessed by Doppler echocardiography. Results-Compared to controls, N2BA/N2B titin-isoforms ratio was reduced to 0.24 in AS (p < 0.001) but increased to 0.51 in AR (p < 0.001). N2BA/N2B titin-isoforms ratio was further reduced in 8 patients with severe (restrictive) diastolic dysfunction (0.17 +/- 0.03, p < 0.001) but was increased in patients with severe systolic dysfunction (0.58 +/- 0.07, p < 0.001). As compared to controls, Fpasive was higher in AS (6.7 +/- 0.2 vs 4.4 +/- 0.4 kN/m2, p < 0.001) but was lower in AR (3.7 +/- 0.2 vs 4.4 +/- 0.4 kN/m2, p < 0.001). Total force was comparable. Fpassive was significantly higher in AS patients with severe than with moderate LV diastolic dysfunction (7.1 +/- 0.5 vs 6.6. +/- 0.6, p = 0.004). Conclusions-titin-isoform expression differs in AS and AR as adaptive response to different pathophysiologic scenarios. Co-expressing isoforms at varying ratios results in modulation of the passive mechanical behavior of the LV at different degree of dysfunction and allows for compensative adjustment of the diastolic/systolic properties of the myocardium.

METHODS: We performed an updated analysis using the National Health and Nutrition Examination Survey 2007-2014 data to investigate the latest trends of prevalence of MetS and its components. MetS was defined based on the modified National Cholesterol Education Program Adult Treatment Panel III criteria. Multiple regression models were used to assess linear trends over the years, after adjusting for sex, age, and race/ethnicity, as appropriate. Sampling weights were considered to account for complex sampling design, and all estimates were adjusted by age by a direct method. RESULTS: During 2007-2014, the age-adjusted weighted prevalence (+/ standard error) of MetS among U.S. adults was 34.3 +/- 0.8%. In age-stratified analysis, 54.9 +/- 1.7% of elderly population aged 60 and over had MetS. When evaluating trends from 2007 to 2014, the prevalence of MetS remained stable in all sex, age, and race/ethnicity groups (P-trends > 0.100 for all). Among the components of MetS, the prevalence of hypertriglyceridemia and fasting hyperglycemia decreased (P-trend <0.050). However, the prevalence of abdominal obesity significantly increased, especially in women (P-trend = 0.009). The prevalence of elevated blood pressure and low high-density lipoprotein cholesterol level remained stable. CONCLUSIONS: The prevalence of MetS remained stable during 2007-2014. However, it was still prevalent in the U.S., especially among the elderly population. The prevalence of abdominal obesity continued to increase in women for which more efforts should be made.

AB - BACKGROUND: Limited data exist regarding the impact of aortic valve calcification (AVC) eccentricity on the risk of paravalvular regurgitation (PVR) and response to balloon post-dilation (BPD) after transcatheter aortic valve replacement (TAVR). We investigated the prognostic value of AVC eccentricity in predicting the risk of PVR and response to BPD in patients undergoing TAVR. METHODS: We analyzed 85 patients with severe aortic stenosis who underwent self-expandable TAVR (43 women; 77.2+/-7.1years). AVC was quantified as the total amount of calcification (total AVC load) and as the eccentricity of calcium (EoC) using calcium volume scoring with contrast computed tomography angiography (CTA). The EoC was defined as the maximum absolute difference in calcium volume scores between 2 adjacent sectors (bi-partition method) or between sectors based on leaflets (leaflet-based method). RESULTS: Total AVC load and bi-partition EoC, but not leaflet-based EoC, were significant predictors for the occurrence of >=moderate PVR, and bi-partition EoC had a better predictive value than total AVC load (area under the curve [AUC]=0.863 versus 0.760, p for difference=0.006). In multivariate analysis, bi-partition EoC was an independent predictor for the risk of >=moderate PVR regardless of perimeter oversizing index. The greater bi partition EoC was the only significant parameter to predict poor response to BPD (AUC=0.775, p=0.004). CONCLUSION: Pre-procedural assessment of AVC eccentricity using CTA as "bi-partition EoC" provides useful predictive information on the risk of significant PVR and response to BPD in patients undergoing TAVR with self expandable valves. PMID- 29472028 TI - Failure mode and bimodal restenosis of drug-coated balloon in femoropopliteal intervention. AB - BACKGROUND: Pattern of DCB restenosis and associated outcomes in facing complex femoropopliteal lesions remain uncertain. METHODS: Data were retrospectively collected from dual centers in Taiwan on patients who underwent treatment with DCBs for femoropopliteal lesions between 2013 and 2016. The restenosis pattern was categorized by the index-treated length. Clinical outcomes and time to DCB restenosis were retrospectively analyzed. Cox proportional hazards model identified restenosis predictors. RESULTS: We recruited a total of 164 patients (91 men; median age 73 years) into the final analysis. The mean lesion length was 204.0 +/- 109.2 mm. Of them, 45% total occlusions, 28% severe calcification and 15% in-stent restenosis were treated. Fifty-five patients have DCB restenosis (28 focal and 27 diffuse-occlusive patterns) over a 55-month follow-up. The median restenosis time emerged as a bimodal pattern with a significant difference between the diffuse-occlusive and focal restenosis group (225 vs. 484 days, P = 0.01). The 1-year patency rate after reintervention for DCB restenosis also was different between both restenosis group (29% vs. 65%, P = 0.017). The anticipated timing of escape for diffuse-occlusive or focal restenosis was 687 and 1068 days, respectively. Independent factors were lesion length (P = 0.049) for diffuse occlusive restenosis and lumen gain of the popliteal artery for focal restenosis (P = 0.034). CONCLUSIONS: This study demonstrated time to DCB failure emerged as a bimodal pattern of distribution and associations of restenosis pattern to subsequent outcomes after the repeated intervention. Exemption from late catchup restenosis required 3-year observation instead of the 1-year mark for conventional treatment.

AB - Hypertension is the leading risk factor for cardiovascular and chronic renal diseases, affecting more than 1 billion people. Fish intake is inversely correlated with the prevalence of hypertension in several, but not all, studies, and intake of fish oil and fish proteins has shown promising potential to delay development of high blood pressure in rats. The effects of baked and raw salmon fillet intake on blood pressure and renal function were investigated in obese Zucker fa/fa rats, which spontaneously develop hypertension with proteinuria and renal failure. Rats were fed diets containing baked or raw salmon fillet in an amount corresponding to 25% of total protein from salmon and 75% of protein from casein, or casein as the sole protein source (control group) for 4 weeks. Results show lower blood pressure and lower urine concentrations of albumin and cystatin C (relative to creatinine) in salmon diet groups when compared to control group. Morphological examinations revealed less prominent hyperfusion damage in podocytes from rats fed diets containing baked or raw salmon when compared to control rats. In conclusion, diets containing baked or raw salmon fillet delayed the development of hypertension and protected against podocyte damage in obese Zucker fa/fa rats. PMID- 29472030 TI - A randomized controlled trial comparing home-based isometric handgrip exercise versus endurance training for blood pressure management. AB - Aerobic endurance exercise (AEX) is an effective treatment in the prevention and management of high blood pressure (BP). Growing evidence suggests potential benefits from isometric handgrip (IHG) exercise, which may promote similar or even larger reductions in BP than AEX. We compared the effects of home-based AEX and home-based IHG on BP. Sixty healthy individuals (31 men; mean age, 33.1 years; mean BP, 126.9 +/- 1.6/84.7 +/- 1.1 mm Hg) were randomized to IHG, AEX, or a control group. Both exercise interventions were performed in the home environment. The IHG group performed daily 4 * 2 minutes sustained grips at 30% of maximal volitional contraction. Participants in the AEX group were advised to perform at least 150 min/wk of aerobic exercise at moderate intensity. Outcome measurements were assessed at baseline and 8 weeks of follow-up. Compared with the control group, AEX resulted in a larger reduction in ambulatory BP; both AEX and IHG exercise tended to induce larger reductions in office systolic BP, and office diastolic BP was significantly more reduced after AEX but not IHG exercise. Responses to training were not significantly different between both the exercise interventions. Eight weeks of home-based AEX results in significant reductions in both ambulatory BP and office BP in healthy adults, whereas IHG reduces only office BP. PMID- 29472031 TI - Preoperative MR imaging for ESMO-ESGO-ESTRO classification of endometrial cancer. AB - OBJECTIVE: To retrospectively investigate whether magnetic resonance imaging (MRI) findings could contribute to predict histologic type, tumor grade and lymphovascular space invasion (LVSI) to improve preoperative assessment of endometrial cancer using the European Society for Medical Oncology (ESMO) European Society for Radiotherapy & Oncology (ESTRO) and European Society of Gynecological Oncology (ESGO) classification. METHODS: Between January 2008 and August 2014, 104 women (mean age, 65+/-11 [SD] years; range, 32-84 years) with International Federation of Gynecology and Obstetrics (FIGO) stage I endometrial cancer underwent preoperative MRI of the pelvis. Two independent readers evaluated tumor heterogeneity and measured tumor size on T2-weighted, diffusion weighted and T1-weighted images obtained after gadolinium chelate administration at 2minutes. The apparent diffusion coefficient (ADC) was generated from pixel ADC from the whole tumor volume. RESULTS: A short axis>24mm on MRI was associated with histopathologic type 2, grade 3 tumor and presence of LVSI (P<0.01). There were no significant differences in minimum, mean and maximum ADC between presence/absence of LVSI. In 9.1% women (9/99), the accuracy of the ESMO-ESGO ESTRO classification with the inclusion of the MRI short-axis criterion was higher than that of the conventional ESMO classification to predict high-risk recurrence endometrial cancer (P=0.02). CONCLUSION: Tumor size reflects histologic type, tumor grade and LVSI in endometrial cancer. FIGO stage 1 endometrial cancer>24mm should be classified preoperatively in the high intermediate or high-risk recurrence risk groups.

PMID- 29472033 TI - Impact of ocean acidification and warming on the productivity of a rock pool community. AB - This study examined experimentally the combined effect of ocean acidification and warming on the productivity of rock pool multi-specific assemblages, composed of coralline algae, fleshy algae, and grazers. Natural rock pool communities experience high environmental fluctuations. This may confer physiological advantage to rock pool communities when facing predicted acidification and warming. The effect of ocean acidification and warming have been assessed at both individual and assemblage level to examine the importance of species interactions in the response of assemblages. We hypothesized that rock pool assemblages have physiological advantage when facing predicted ocean acidification and warming. Species exhibited species-specific responses to increased temperature and pCO2. Increased temperature and pCO2 have no effect on assemblage photosynthesis, which was mostly influenced by fleshy algal primary production. The response of coralline algae to ocean acidification and warming depended on the season, which evidenced the importance of physiological adaptations to their environment in their response to climate change. We suggest that rock pool assemblages are relatively robust to changes in temperature and pCO2, in terms of primary production. PMID- 29472034 TI - Contrasting impacts of light reduction on sediment biogeochemistry in deep- and shallow-water tropical seagrass assemblages (Green Island, Great Barrier Reef). AB - Seagrass meadows increasingly face reduced light availability as a consequence of coastal development, eutrophication, and climate-driven increases in rainfall leading to turbidity plumes. We examined the impact of reduced light on above ground seagrass biomass and sediment biogeochemistry in tropical shallow- (~2 m) and deep-water (~17 m) seagrass meadows (Green Island, Australia). Artificial shading (transmitting ~10-25% of incident solar irradiance) was applied to the shallow- and deep-water sites for up to two weeks. While above-ground biomass was unchanged, higher diffusive O2 uptake (DOU) rates, lower O2 penetration depths, and higher volume-specific O2 consumption (R) rates were found in seagrass vegetated sediments as compared to adjacent bare sand (control) areas at the shallow-water sites. In contrast, deep-water sediment characteristics did not differ between bare sand and vegetated sites. At the vegetated shallow-water site, shading resulted in significantly lower hydrogen sulphide (H2S) levels in the sediment. No shading effects were found on sediment biogeochemistry at the deep-water site. Overall, our results show that the sediment biogeochemistry of shallow-water (Halodule uninervis, Syringodium isoetifolium, Cymodocea rotundata and C. serrulata) and deep-water (Halophila decipiens) seagrass meadows with different species differ in response to reduced light. The light-driven dynamics of the sediment biogeochemistry at the shallow-water site could suggest the presence of a microbial consortium, which might be stimulated by photosynthetically produced exudates from the seagrass, which becomes limited due to lower seagrass photosynthesis under shaded conditions. PMID- 29472035 TI - An overview of the accumulation of microcystins in aquatic ecosystems. AB - Cyanotoxins produced by toxic cyanobacteria pose a major, worldwide environmental threat to freshwater ecosystems. Microcystins (MCs) are considered to be the most hazardous groups. Indeed, some of the largest aquatic ecosystems on the earth are being contaminated with MCs. Questions have arisen regarding their transfer and bioaccumulation in natural environment. This review summarizes the present state of knowledge regarding toxic cyanobacteria and MCs, with a specific focus on their distribution in different components of aquatic ecosystems. Their accumulation in water columns, aquatic animals, plants, and sediments is summarized. MCs have been contaminating all areas of the aquatic ecosystems. Of these, the water column was the most contaminated with MCs and served as an intermediate transmission substation. Via this route, MCs could enter to other stations such as sediment, animals, aquatic and terrestrial plants. Therefore, the use of water contaminated with MCs may induce food chain contaminations with considerable health risks. PMID- 29472036 TI - Lanthanum-doped silica xerogels for the removal of fluorides from waters. AB - The objective of this study was to determine the influence of different operational variables on fluoride (F-) removal from waters using lanthanum (La) doped silica xerogels and the mechanisms involved in this process. Accordingly, four xerogels were synthesized, one acting as blank (X-B), two doped with LaCl3 and dried at different temperatures (X-LaCl and X-LaCl-M), and a fourth doped with La2O3 (X-LaO). The results show that fluorides are only removed when La doped xerogels are utilized. In addition, X-LaCl yielded the highest adsorption capacity, removing 28.44% of the initial fluoride concentration at a solution pH of 7. Chemical characterization of materials confirmed that fluoride removal from waters is due to the precipitation of LaF3 on the surface of La-doped xerogels. The presence of dissolved organic matter on the aqueous solution also reduce the removal capacity of La xerogels. Finally, analysis of the influence of solution pH revealed that the adsorption capacity of all xerogels was highest at a solution pH of 7. PMID- 29472037 TI - Misplacing V1 and V2 can have clinical consequences. AB - The precordial electrocardiogram (ECG) leads V1 and V2 are often misplaced. Such misplacement usually involves placing these leads too high on the chest. The resulting ECG may generate erroneous ECG patterns: e.g. incomplete right bundle branch block, anterior T wave inversion, septal Q waves, ST-segment elevation. These features may falsely suggest acute or old cardiac ischemia, pulmonary embolism, or a type-2 Brugada pattern. On rare occasion, conversely, high placement of V1 and V2 may reveal a true type-1 Brugada pattern. The emergency clinician needs to be aware of the possibility of lead misplacement, and should know how to suspect it based on unusual P wave morphology in V1 and V2. PMID- 29472038 TI - Prognostic performance of Emergency Severity Index (ESI) combined with qSOFA score. AB - OBJECTIVE: We conducted this study to investigate whether ESI combined with qSOFA score (ESI+qSOFA) predicts hospital outcome better than ESI alone in the emergency department (ED). METHODS: This was a retrospective study for patients aged over 15years who visited an ED of a tertiary referral hospital from January 1st, 2015 to December 31st, 2015. We calculated and compared predictive performances of ESI alone and ESI+qSOFA for prespecified outcomes. The primary outcome was hospital mortality, and the secondary outcome was composite outcome of in-hospital mortality and ICU admission. We calculated in-hospital mortality rates by positive qSOFA in each subgroup divided according to ESI levels (1, 2, 3, 4+5). RESULTS: 43,748 patients were enrolled. The area under receiver operating characteristics curves were higher in ESI+qSOFA than in ESI alone for both mortality and composite outcome (0.786 vs. 0.777, P<.001 for mortality; 0.778 vs. 0.774, P<.001 for composite outcome). In each subgroup divided by ESI levels, patients with positive qSOFA had significantly higher in-hospital mortality rate compared to those with negative qSOFA (20.4% vs. 14.7%, P=.117 in ESI level 1 subgroup; 11.3% vs. 2.7%, P=.001 in ESI level 2 subgroup; 2.3% vs. 0.4%, P<.001 in ESI level 3 subgroup; 0.0% vs. 0.0% in ESI level 4 or 5 subgroup). CONCLUSION: The prognostic performance of ESI+qSOFA for in-hospital mortality was significantly higher than that of ESI alone. Within each subgroup, patients with positive qSOFA had higher in-hospital mortality compared to those with negative qSOFA. PMID- 29472039 TI - Safety of bolus-dose phenylephrine for hypotensive emergency department patients. AB - INTRODUCTION: Bolus-dose phenylephrine (BDPE) is routinely used to treat hypotension in the operating room. BDPE's fast onset of action and ability to be administered peripherally have prompted calls for its use in the Emergency Department (ED). There are few published data on the safety of BDPE use in the ED. Primary concerns include BDPE's potential to cause dangerous hypertension or reflex bradycardia. We hypothesize that BDPE is a safe short-term vasopressor choice for hypotensive ED patients. METHODS: We conducted a structured chart review for all patients who received BDPE from preloaded syringes over 42months. We defined an adverse event (AE) as sBP>180, dBP>110, or HR<50 within 30min of receiving BDPE. We defined a serious adverse event (SAE) as an AE with pharmacologic intervention to correct vital sign abnormality. We also compared mean arterial pressure (MAP), sBP, and dBP pre/post BDPE administration to assess effectiveness. We used a two-sample t-test to assess for differences between the mean delta MAP after low versus high-dose BDPE. RESULTS: We identified 181 cases of ED use. 147 cases had complete pre/post vital signs. We identified 5 AEs and no SAEs. Three patients developed sBP>180mmHg. The patients suffered no apparent harm. No patients had dBP>110. Two patients developed bradycardia post-drug. In both cases, MAP improved despite bradycardia. CONCLUSIONS: BDPE does not appear to cause reflex bradycardia or hypertension requiring intervention among hypotensive ED patients. The apparent safety of BDPE should be confirmed in prospective trials. PMID- 29472040 TI - Nasal cannula during noninvasive positive pressure ventilation: Combining preoxygenation with apneic oxygen. PMID- 29472042 TI - Identification of predictors for wound complications following preoperative or postoperative radiotherapy in extremity soft tissue sarcoma. AB - INTRODUCTION: In extremity soft tissue sarcoma (ESTS), external beam radiotherapy (EBRT) has been used in addition to limb-sparing surgery (LSS). This study aims to identify predictors for major wound complication (MWC) development following EBRT and LSS in ESTS. METHODS: This retrospective study includes ESTS patients treated with EBRT and LSS between 2005 and 2017. Two groups were formed; Group I included preoperatively irradiated patients, whereas Group II included patients who underwent postoperative EBRT. Multivariate logistic regression analyses were performed to create a prediction model for MWC development. RESULTS: One hundred twenty-seven patients were included, 58 patients (45.7%) in Group I and 69 patients (54.3%) in Group II. Some differences in baseline characteristics were found between the groups, e.g. in tumor size and grade, histological subtype and total RT dose. Twenty-three patients (39.7%) in Group I and 14 patients (20.3%) in Group II developed a MWC (p = 0.02). Preoperative EBRT was identified as independent predictor for MWC development, OR 2.75 (95%CI 1.21-6.26), p = 0.02. Furthermore, a trend towards an increased MWC risk was shown for patients' age (OR 1.02 (0.99-1.04)), delayed wound closure (OR 3.20 (0.64-16.02)) and negative surgical margins (OR 2.26 (0.72-7.11)). The area under the curve (AUC) of the model was 0.68 (0.57-0.79). CONCLUSIONS: This study corroborates the increased MWC risk following preoperative EBRT in ESTS. It remains important to carefully weigh the MWC risk against the expected long-term functional outcome, and to consider the liberal use of primary plastic surgical reconstructions in an individualized multidisciplinary tumor board prior to treatment. PMID- 29472043 TI - Neoadjuvant and adjuvant strategies in retroperitoneal sarcoma. AB - Extended surgery remains the mainstay of treatment in retroperitoneal sarcoma, although conflicting data exist on the benefit of neoadjuvant and adjuvant therapies, particularly with regard to tumour grade and histological type. Experience of radiotherapy and chemotherapy in extremity soft tissue sarcoma can inform treatment strategies, however these data cannot be universally extrapolated to the retroperitoneum where disease biology and anatomical considerations are different. The present review sets a historical context before discussing recent evidence and on-going multi-centre trials in retroperitoneal sarcoma. Promising data on histologically- and molecularly-targeted chemotherapy are discussed and the need for centralisation of retroperitoneal sarcoma services in order to facilitate large international collaborative trials is emphasised.

PMID- 29472045 TI - Dosimetric properties of alpha-Al2O3: Tm+PTFE phosphor. AB - A new alpha-Al2O3 doped with Tm3+ ions was obtained by combustion method; doped alpha-Al2O3 in the powder form was mixed with polytetrafluoroethylene resin (PTFE) to obtain dosimeters in pellet form, in order to be used as radiation dosimeter. The glow curve, linearity, lower detection limit, repeatability and fading, were studied. The kinetic parameters were determined by deconvolution method. Morphological characteristics were studied by low vacuum scanning electron microscopy and X-ray diffraction. Results showed that alpha-Al2O3+PTFE obtained is a promising material to radiation dosimetry. PMID- 29472046 TI - Functional range of motion in the metacarpophalangeal joints of the hand measured by single axis electric goniometers. AB - BACKGROUND: The functional range of motion (fROM) of the metacarpophalangeal (MCP) joints during the performance of activities of daily living (ADL) has not yet been established. This study aimed to determine the fROM of all five digits and verify the accuracy and reproducibility of dynamic angle measurement using a single-axis electric goniometer (EG) during ADL movements of the hand. METHODS: This was a cross-sectional study. In EG suitability testing, we first confirmed the angles of a three-dimensional calibration device 10 times, and then compared EG readings with those determined by tomosynthesis images. Next, we determined the fROM of the MCP joints by evaluating all five digits of the dominant hands of 10 healthy adults performing 16 ADL. Intra-rater reproducibility of MCP joint data during task performance was assessed in two healthy adults. RESULTS: Static measurements of the triangular object showed variance to be within one degree in 39 of 40 trials. Differences between angles measured by the EG and those depicted by radiograph were a range of plus or minus five degrees in 88 of 96 digits. The fROM values for the thumb and index, middle, ring, and little fingers were -7.5 to 35.3, 10.6 to 67.8, 4.0 to 79.9, 3.0 to 83.9, and 2.9-91.4 degrees of flexion, respectively. Flexion angle in the fROM of the index finger was significantly smaller than those of the ring and little fingers. The flexion and extension angles of the thumb were significantly smaller than those of the four ulnar fingers. The intra-rater correlation coefficients of two participants were high at 0.94 and 0.93, respectively. CONCLUSIONS: The method adopted in this study exhibited excellent accuracy and reproducibility and was therefore considered suitable for the real-time establishment of fROM flexion-extension angles of the MCP joints for all five digits. Our data are useful as a target arc of motion in the treatment of MCP joint disease or injury. PMID- 29472047 TI - Prevalence estimation and familial tendency of common forefoot deformities in Turkey: A survey of 2662 adults. AB - OBJECTIVE: This survey was designed to evaluate the prevalence estimations of HV, bunionette, hammertoe as well as their relations to shoe wearing and also familial tendency, in Turkey. MATERIAL AND METHODS: Two thousand six hundred sixty two volunteers (1615 females and 1047 males) with a mean age of 34.15 +/- 14.23 (range; 18 to 96) years were asked to answer the predetermined questionnaire between January and June, 2016. Hallux valgus, hammertoe and bunionette images were provided as references and every adult participant without any known forefoot problems or past forefoot surgery history was asked to rate his/her foot and to respond the questions about family history and shoe wearing habits. Responses were statistically analyzed. RESULTS: The prevalence estimations of hallux valgus, bunionette and hammertoe were calculated as 54.3%, 13.8% and 8.9% and positive family history rates were 53.2%, 61.2% and 56.1%, respectively. All three deformities were more common in females than in males (p < 0.001). Nonetheless the older age group reported significantly higher prevalence rates for only HV (p < 0.001). Likewise, among the three deformities, females reported a higher rate of positive family history only in HV compared to men (p < 0.001). Constricting shoe wear was found to affect HV incidence in women (p < 0.001) and bunionette incidence in both sexes (p < 0.01). CONCLUSION: This study concludes that forefoot deformities are common with high familial tendency. Hence it is worthwhile to work on molecular genetics and this may enable the anticipation of forthcoming deformities in order to take early action in prevention, in nearly the half of the population. PMID- 29472048 TI - Oral lichen planus - Differential diagnoses, serum autoantibodies, hematinic deficiencies, and management. AB - Oral lichen planus (OLP) is a chronic inflammatory oral mucosal disease that occurs more frequently in middle-aged and elderly female patients. Previous studies indicate that OLP is a T-cell dysfunction-induced localized autoimmune disease. Clinically, six types of OLP, namely reticular, papular, plaque-like, atrophic/erosive, ulcerative, and bullous types, can be identified. OLP more commonly affects buccal mucosa, tongue, and gingiva. It always has a bilateral and symmetric distribution of the oral lesions. Plaque-like and atrophic/erosive OLP may be misdiagnosed as oral leukoplakia and oral erythroleukoplakia, respectively. Our previous study found serum autoantibodies in 195 (60.9%) of the 320 OLP patients. Specific serum anti-nuclear, anti-smooth muscle, anti mitochondrial, gastric parietal cell, thyroglobulin, and thyroid microsomal autoantibodies are present in 28.1%, 8.4%, 1.6%, 26.3%, 21.3%, and 24.4% of 320 OLP patients, respectively. Furthermore, we also discovered that 21.9%, 13.6%, 7.1%, 0.3%, and 14.8% of 352 OLP patients have hemoglobin, iron, vitamin B12, and folic acid deficiencies, and abnormally high serum homocysteine level, respectively. Therefore, it is very important to examine the serum autoantibody, hematinic and homocysteine levels in OLP patients before starting the treatments for OLP patients. Because OLP is an immunologically-mediated disease, corticosteroids are the drugs of choice for treatment of OLP. PMID- 29472041 TI - Adherence to best practice consensus guidelines for implant-based breast reconstruction: Results from the iBRA national practice questionnaire survey. AB - INTRODUCTION: The 2008 National Mastectomy and Breast Reconstruction Audit demonstrated marked variation in the practice and outcomes of breast reconstruction in the UK. To standardise practice and improve outcomes for patients, the British professional associations developed best-practice guidelines with specific guidance for newer mesh-assisted implant-based techniques. We explored the degree of uptake of best-practice guidelines within units performing implant-based reconstruction (IBBR) as the first phase of the implant Breast Reconstruction Evaluation (iBRA) study. METHODS: A questionnaire developed by the iBRA Steering Group was completed by trainee and consultant leads at breast and plastic surgical units across the UK. Simple summary statistics were calculated for each survey item to assess compliance with current best-practice guidelines. RESULTS: 81 units from 79 NHS Trusts completed the questionnaire. Marked variation was observed in adherence to guidelines, especially those relating to clinical governance and infection prevention strategies. Less than half (n = 28, 47%) of units obtained local clinical governance board approval prior to offering new mesh-based techniques and prospective audit of the clinical, cosmetic and patient-reported outcomes of surgery was infrequent. Most units screened for methicillin-resistant staphylococcus aureus prior to surgery but fewer than 1 in 3 screened for methicillin-sensitive strains. Laminar-flow theatres (recommended for IBBR) were not widely-available with less than 1 in 5 units having regular access. Peri operative antibiotics were widely-used, but the type and duration were highly variable. CONCLUSIONS: The iBRA national practice questionnaire has demonstrated variation in reported practice and adherence to IBBR guidelines. High-quality evidence is urgently required to inform best practice. PMID- 29472050 TI - 2017-A Banner Year for Thoracic Oncology.

It is challenging to include detailed physiological descriptions of cellular components into human auditory models because single-cell data stems from invasive animal recordings while human reference data only exists in the form of population responses (e.g., otoacoustic emissions, auditory evoked potentials). To embed physiological models within a comprehensive human auditory periphery framework, it is important to capitalize on the success of basic functional models of hearing and render their descriptions more biophysical where possible. At the same time, comprehensive models should capture a variety of key auditory features, rather than fitting their parameters to a single reference dataset. In this study, we review and improve existing models of the IHC-AN complex by updating their equations and expressing their fitting parameters into biophysical quantities. The quality of the model framework for human auditory processing is evaluated using recorded auditory brainstem response (ABR) and envelope-following response (EFR) reference data from normal and hearing-impaired listeners. We present a model with 12 fitting parameters from the cochlea to the brainstem that can be rendered hearing impaired to simulate how cochlear gain loss and synaptopathy affect human population responses. The model description forms a compromise between capturing well-described single-unit IHC and AN properties and human population response features.

PMID- 29472064 TI - Major postoperative complications compromise oncological outcomes of patients with intrahepatic cholangiocarcinoma after curative resection - A 13-year cohort in a tertiary center. AB - BACKGROUND/OBJECTIVE: Hepatectomy is the mainstay of curative treatment for intrahepatic cholangiocarcinoma (ICC). The relationship between postoperative complication and oncological outcome has not been defined. We aimed to elucidate the effect of postoperative complication on long-term survival of ICC patients after curative resection. METHODS: Data of consecutive patients who had curative resection for ICC at our hospital from 1991 to 2013 were reviewed. Patients with cholangiohepatocellular carcinoma, metastatic adenocarcinoma or Klaskin tumor were excluded. Clinicopathological data and postoperative events were extracted from database for survival analysis. RESULTS: There were 107 patients in our series. Their median age was 61 years. The median follow-up time was 24 months. The median tumor size was 6 cm. Major hepatectomy was required in 52.3% of them. The median operation time and blood loss was 439 minutes and 0.9L respectively. R0 resection was achieved in 88.8% of them. The median length of stay was 11 days. The 30-day and 90-day mortality was 2.5% and 6.8% respectively. Major complications were found in 20.6% of them. Patients with postoperative complications had significantly inferior survival than patients without (3-yr DFS 38% vs. 27%, P = 0.001; 3-yr overall: 51% vs. 27%, P < 0.001). Multivariable analysis showed that postoperative complication was an independent factor associated with disease-free survival (OR 1.9 95% C.I. 1.10-3.24, P = 0.021) and overall survival (OR 2.1, 95% C.I. 1.13-3.93, P = 0.018). CONCLUSION: Postoperative complication has a significant impact on ICC patients' long-term survival. Extra measures such as adjuvant chemotherapy should be considered for patients who develop major complications after surgery.

PMID- 29472066 TI - Serum levels of irisin predict short-term outcomes in ischemic stroke. AB - OBJECTIVE: Irisin is a 112-amino acid peptide found in rat and human skeletal muscle after exercise. Previous studies had suggested that higher circulating irisin levels were associated with an increased risk of vascular atherosclerosis and cardiovascular diseases. In this study, we determined irisin levels in serum, and investigated their associations with functional outcomes in a 3-month follow up study in Chinese patients with first-ever acute ischemic stroke (AIS). METHODS: From September 2015 to December 2016, consecutive first-ever AIS patients admitted to the Department of Emergency of our hospital were identified. Serum irisin levels were measured at admission. Functional impairment was evaluated at discharge using the modified Rankin scale. The levels of irisin were expressed as median and interquartile ranges [IQR]. RESULTS: The irisin level was obtained in 324 patients (97.6%) with a median value of 291.2 ng/ml (IQR: 214.1 404.2 ng/ml). There were significantly negative correlations between levels of irisin and NHISS (r = -0.272; P < 0.001) and BMI (r = -0.193; P = 0.003). A poor functional outcome was found in 99 patients (30.6%; 95%CI: 25.5-35.6%). The poor functional outcome distribution across the irisin quartiles ranged between 51.9% (first quartile: Q1) to 12.4% (fourth quartile: Q4). In a multivariate model using the Q1 of irisin vs. Q2-4 together with the clinical variables, the marker displayed prognostic information and increased risk of poor outcomes by 94% (OR for Q1, 1.94 [95% CI, 1.19-3.42]; P = 0.018) and mortality 66% (OR for Q1, 1.66 [95% CI, 1.11-3.07]; P = 0.009). In addition, a model containing known risk factors plus irisin compared with a model containing known risk factors without irisin showed a greater discriminatory ability to predict poor outcomes (P = 0.01) and mortality (P = 0.02). CONCLUSIONS: A low serum irisin level is a predictor of poor early functional outcome in ischemic stroke patients. The underlying mechanisms of these associations remain to be investigated. PMID- 29472067 TI - Neurophysiology of hearing in patients with mucopolysaccharidosis type IV. AB - BACKGROUND: Hearing impairment is a common problem in patients with mucopolysaccharidosis IV (MPS IV) throughout their life. Many of the adult patients with MPS IV exhibit permanent or severe hearing loss. However, there has been no systematic review of detailed audiological test results in MPS IV. MATERIALS AND METHODS: Fourteen individuals with MPS IV (13 MPS IVA and 1 MPS IVB; aged between 12 and 38 years old) participated in the current study. We obtained auditory neurophysiological responses (auditory brainstem responses and otoacoustic emissions test) in addition to pure-tone audiometry and middle ear function tests (tympanometry and acoustic reflexes). RESULTS: The results indicated various levels and types of hearing loss with abnormal neurophysiological responses even in those patients with MPS IVA with normal pure tone thresholds. We also found a strong relationship between height (short stature is an indicator of skeletal severity) and hearing sensitivity as well as a strong relationship between height and outer hair cell function in the inner ear (measured by otoacoustic emissions) among MPS IVA patients. CONCLUSION: The strong correlation between reduced height and hearing loss indicates that patients with severe skeletal dysplasia may be at higher risk of developing more severe hearing loss. More importantly, the spectrum of hearing disorders indicates that MPS IV patients should have annual neurophysiological hearing tests in addition to audiometric testing from an early age regardless of their skeletal severity to more carefully monitor disease progression. PMID- 29472068 TI - Childhood cardiorespiratory fitness, muscular fitness and adult measures of glucose homeostasis. AB - OBJECTIVES: To assess whether childhood cardiorespiratory fitness (CRF) and muscular fitness phenotypes (strength, power, endurance) predict adult glucose homeostasis measures. DESIGN: Prospective longitudinal study. METHODS: Study examining participants who had physical fitness measured in childhood (aged 7-15 years) and who attended follow-up clinics approximately 20 years later and provided a fasting blood sample which was tested for glucose and insulin. Physical fitness measurements included muscular strength (right and left grip, shoulder flexion, shoulder and leg extension), power (standing long jump distance) and endurance (number of push-ups in 30s), and CRF (1.6km run duration). In adulthood, fasting glucose and insulin levels were used to derive glucose homeostasis measures of insulin resistance (HOMA2-IR) and beta cell function (HOMA2-beta). RESULTS: A standard deviation increase in childhood CRF or muscular strength (males) was associated with fasting glucose (CRF: beta= 0.06mmol/L), fasting insulin (CRF: beta=-0.73mU/L; strength: beta=-0.40mU/L), HOMA2-IR (CRF: beta=-0.06; strength: beta=-0.05) and HOMA2-beta (CRF: beta= 3.06%; strength: beta=-2.62%) in adulthood, independent of the alternative fitness phenotype (all p<0.01). Adjustment for childhood waist circumference reduced the effect by 17-35% for CRF and 0-15% for muscular strength (males) and statistical significance remained for all associations expect between CRF, fasting glucose and HOMA2-beta (p>0.06). CONCLUSIONS: CRF and muscular fitness in childhood were inversely associated with measures of fasting insulin, insulin resistance and beta cell function in adulthood. Childhood CRF and muscular fitness could both be potential independent targets for strategies to help reduce the development of adverse glucose homeostasis. PMID- 29472069 TI - Idiopathic thoracic spinal cord herniation. AB - Idiopathic spinal cord herniation represents an uncommon and unique diagnostic entity, most commonly affecting middle-aged individuals, with a nearly twofold female predilection. It most characteristically affects the mid-thoracic spine, with the herniation occurring ventrally or ventrolaterally. Clinical presentation is typically a slowly-progressive myelopathy, with Brown-Sequard syndrome occurring more frequently than spastic paraparesis. Diagnosis is made by imaging, with high-resolution or phase-contrast MR sequences and/or CT myelography. Treatment should be individualized, with options including conservative management with routine follow-up and surgical intervention. We review the literature on this interesting topic and report on, and present our technique for, operative reduction and repair of idiopathic spinal cord herniation in a 66 year-old woman. PMID- 29472070 TI - Investigating the causes of low detectability of pesticides in fruits and vegetables analysed by high-performance liquid chromatography - Time-of-flight. AB - Because of the high number of possible pesticide residues and their chemical complexity, it is necessary to develop methods which cover a broad range of pesticides. In this work, a qualitative multi-screening method for pesticides was developed by use of HPLC-ESI-Q-TOF. 110 pesticides were chosen for the creation of a personal compound database and library (PCDL). The MassHunter Qualitative Analysis software from Agilent Technologies was used to identify the analytes. The software parameter settings were optimised to produce a low number of false positive as well as false negative results. The method was validated for 78 selected pesticides. However, the validation criteria were not fulfilled for 45 analytes. Due to this result, investigations were started to elucidate reasons for the low detectability. It could be demonstrated that the three main causes of the signal suppression were the co-eluting matrix (matrix effect), the low sensitivity of the analyte in standard solution and the fragmentation of the analyte in the ion source (in-source collision-induced dissociation). In this paper different examples are discussed showing that the impact of these three causes is different for each analyte. For example, it is possible that an analyte with low signal intensity and an intense fragmentation in the ion source is detectable in a difficult matrix, whereas an analyte with a high sensitivity and a low fragmentation is not detectable in a simple matrix. Additionally, it could be shown that in-source fragments are a helpful tool for an unambiguous identification. PMID- 29472071 TI - Prediction of collision cross section and retention time for broad scope screening in gradient reversed-phase liquid chromatography-ion mobility-high resolution accurate mass spectrometry. AB - Exact mass, retention time (RT), and collision cross section (CCS) are used as identification parameters in liquid chromatography coupled to ion mobility high resolution accurate mass spectrometry (LC-IM-HRMS). Targeted screening analyses are now more flexible and can be expanded for suspect and non-targeted screening. These allow for tentative identification of new compounds, and in-silico predicted reference values are used for improving confidence and filtering false positive identifications. In this work, predictions of both RT and CCS values are performed with machine learning using artificial neural networks (ANNs). Prediction was based on molecular descriptors, 827 RTs, and 357 CCS values from pharmaceuticals, drugs of abuse, and their metabolites. ANN models for the prediction of RT or CCS separately were examined, and the potential to predict both from a single model was investigated for the first time. The optimized combined RT-CCS model was a four-layered multi-layer perceptron ANN, and the 95th prediction error percentiles were within 2 min RT error and 5% relative CCS error for the external validation set (n = 36) and the full RT-CCS dataset (n = 357). 88.6% (n = 733) of predicted RTs were within 2 min error for the full dataset. Overall, when using 2 min RT error and 5% relative CCS error, 91.9% (n = 328) of compounds were retained, while 99.4% (n = 355) were retained when using at least one of these thresholds. This combined prediction approach can therefore be useful for rapid suspect/non-targeted screening involving HRMS, and will support current workflows. PMID- 29472072 TI - Parallel loading and complete automation of a 3-step mAb purification process for multiple samples using a customized preparative chromatography instrument with networked pumps. AB - Advancement in high-throughput screening methods of novel therapeutic proteins for early stage research and development, specifically mAbs, have given mid-scale (milligram to gram scale) purification groups access to more of these molecules. The available purification technologies built to support mid-scale production was not efficient or versatile enough to keep up with this surge. To remedy this problem, we have designed and built a custom instrument using an AKTA Pure. This system enables parallel processing up to 5 samples and has the versatility to perform 1- to 3-step purification processes in a single queue. Furthermore, a unique purification scheme can be selected for each of the five samples in the queue. Overall processing time has reduced by 83% compared to manual, non parallel load methods. Here, we describe our novel approach and demonstrate the flexibility, speed and efficiency of the instrument. PMID- 29472073 TI - Positional uncertainty of vaginal cuff and feasibility of implementing portable bladder scanner in postoperative cervical cancer patients. AB - PURPOSE: To propose a geometrical margin for definition of the vaginal cuff PTV using only CT images of the full bladder (CTfull) in postoperative cervical cancer patients. METHODS: Twenty-nine operated cervical cancer patients underwent volumetric arc therapy with a bladder filling protocol. This study assessed bladder filling using a portable bladder scanner and cone-beam computed tomography (CBCT) during the entire treatment period. The measured bladder volumes with a BladderScan(r) were compared with the delineated volume on CBCT. Titanium clips in the vaginal cuff were analysed to assess geometrical uncertainty and the influence of rectal and bladder volume changes. RESULTS: BladderScan(r) showed good agreement with the delineated volume (R = 0.80). The volume changes in the bladder have a greater influence on the clip displacements than in the rectum. The 95th percentile of uncertainty of the clips in reference to CTfull in the right-left (RL), the superoinferior (SI), and the anteroposterior (AP) was 0.32, 0.65, and 1.15 cm, respectively. From this result and intra-fractional movements of the vaginal cuff reported by Haripotepornkul, a new geometrical margin was proposed for definition of the vaginal cuff planning target volume (PTV): 0.5, 0.9, and 1.4 cm in the RL, SI, and AP directions, respectively. CONCLUSIONS: A new geometrical margin was proposed for definition of the vaginal cuff PTV based on CTfull, which will be needless of empty bladder at the planning CT scan. This method allows patients to reduce the burden and efficient routine CT scans can be improved. PMID- 29472074 TI - Feasibility of using a dose-area product ratio as beam quality specifier for photon beams with small field sizes. AB - PURPOSE: To investigate the feasibility of using the ratio of dose-area product at 20 cm and 10 cm water depths (DAPR20,10) as a beam quality specifier for radiotherapy photon beams with field diameter below 2 cm. METHODS: Dose-area product was determined as the integral of absorbed dose to water (Dw) over a surface larger than the beam size. 6 MV and 10 MV photon beams with field diameters from 0.75 cm to 2 cm were considered. Monte Carlo (MC) simulations were performed to calculate energy-dependent dosimetric parameters and to study the DAPR20,10 properties. Aspects relevant to DAPR20,10 measurement were explored using large-area plane-parallel ionization chambers with different diameters. RESULTS: DAPR20,10 was nearly independent of field size in line with the small differences among the corresponding mean beam energies. Both MC and experimental results showed a dependence of DAPR20,10 on the measurement setup and the surface over which Dw is integrated. For a given setup, DAPR20,10 values obtained using ionization chambers with different air-cavity diameters agreed with one another within 0.4%, after the application of MC correction factors accounting for effects due to the chamber size. DAPR20,10 differences among the small field sizes were within 1% and sensitivity to the beam energy resulted similar to that of established beam quality specifiers based on the point measurement of Dw. CONCLUSIONS: For a specific measurement setup and integration area, DAPR20,10 proved suitable to specify the beam quality of small photon beams for the selection of energy-dependent dosimetric parameters. PMID- 29472075 TI - A novel high-resolution 2D silicon array detector for small field dosimetry with FFF photon beams. AB - PURPOSE: Flattening filter free (FFF) beams are increasingly being considered for stereotactic radiotherapy (SRT). For the first time, the performance of a monolithic silicon array detector under 6 and 10 MV FFF beams was evaluated. The dosimeter, named "Octa" and designed by the Centre for Medical Radiation Physics (CMRP), was tested also under flattened beams for comparison. METHODS: Output factors (OFs), percentage depth-dose (PDD), dose profiles (DPs) and dose per pulse (DPP) dependence were investigated. Results were benchmarked against commercially available detectors for small field dosimetry. RESULTS: The dosimeter was shown to be a 'correction-free' silicon array detector for OFs and PDD measurements for all the beam qualities investigated. Measured OFs were accurate within 3% and PDD values within 2% compared against the benchmarks. Cross-plane, in-plane and diagonal DPs were measured simultaneously with high spatial resolution (0.3 mm) and real time read-out. A DPP dependence (24% at 0.021 mGy/pulse relative to 0.278 mGy/pulse) was found and could be easily corrected for in the case of machine specific quality assurance applications. CONCLUSIONS: Results were consistent with those for monolithic silicon array detectors designed by the CMRP and previously characterized under flattened beams only, supporting the robustness of this technology for relative dosimetry for a wide range of beam qualities and dose per pulses. In contrast to its predecessors, the design of the Octa offers an exhaustive high-resolution 2D dose map characterization, making it a unique real-time radiation detector for small field dosimetry for field sizes up to 3 cm side. PMID- 29472076 TI - Robustness of VMAT and 3DCRT plans toward setup errors in radiation therapy of locally advanced left-sided breast cancer with DIBH. AB - PURPOSE: The aim of our study was to evaluate and compare the robustness of treatment plans produced using the volumetric modulated arc-therapy (VMAT) and the standard three-dimensional conformal radiotherapy (3DCRT) techniques by estimating perturbed doses induced by localization offsets for deep inspiration breath-hold (DIBH) in locally advanced breast cancer radiation therapy. METHODS: Twenty patients with left breast carcinoma requiring radiation therapy were analysed in this planning study. Robust VMAT plans regarding minimum CTV doses and standard 3DCRT plans were produced, and perturbed doses were calculated in accordance with localization values from the weekly offline imaging protocol. Offsets from 5 weeks were summed to a perturbed overall treatment plan. Dose criteria for evaluation were coverage and homogeneity of the target, as well as doses to organs at risk. RESULTS: VMAT plans resulted in significantly better target coverage compared to 3DCRT, as well as lowered doses to heart and left anterior descending artery, while the perturbed doses were less variable for VMAT than 3DCRT plans. Homogeneity was significantly improved in VMAT plans. The statistical analysis taking all organs into account found that VMAT plans were more robust than 3DCRT to localization offsets (p = .001). The overall mean setup deviation for the DIBH-patients was less than 2 mm in all directions. CONCLUSIONS: VMAT plans were more robust on average than conventional 3DCRT plans for DIBH when localization errors were taken into consideration. The combination of robust VMAT planning and DIBH generally improves the homogeneity and target doses. PMID- 29472077 TI - Evaluation of size, morphology, concentration, and surface effect of gold nanoparticles on X-ray attenuation in computed tomography. AB - Increasing attention has been focused on the use of nanostructures as contrast enhancement agents in medical imaging, especially in computed tomography (CT). To date, gold nanoparticles (GNPs) have been demonstrated to have great potential as contrast agents for CT imaging. This study was designed to evaluate any effect on X-ray attenuation that might result from employing GNPs with a variety of shapes, sizes, surface chemistries, and concentrations. Gold nanorods (GNRs) and spherical GNPs were synthesized for this application. X-ray attenuation was quantified by Hounsfield unit (HU) in CT. Our findings indicated that smaller spherical GNPs (13 nm) had higher X-ray attenuation than larger ones (60 nm) and GNRs with larger aspect ratio exhibited great effect on X-ray attenuation. Moreover, poly ethylene glycol (PEG) coating on GNRs declined X-ray attenuation as a result of limiting the aggregation of GNRs. We observed X-ray attenuation increased when mass concentration of GNPs was elevated. Overall, smaller spherical GNPs can be suggested as a better alternative to Omnipaque, a good contrast agent for CT imaging. This data can be also considered for the application of gold nanostructures in radiation dose enhancement where nanoparticles with high X-ray attenuation are applied. PMID- 29472078 TI - Intercomparison of 99mTc, 18F and 111In activity measurements with radionuclide calibrators in Belgian hospitals. AB - This study presents current status of performance of radiopharmaceutical activity measurements using radionuclide calibrators in Belgium. An intercomparison exercise was performed among 15 hospitals to test the accuracy of 99mTc, 18F and 111In activity measurements by means of radionuclide calibrators. Four sessions were held in different geographical regions between December 2013 and February 2015. The data set includes measurements from 38 calibrators, yielding 36 calibrations for 99mTc and 111In, and 21 calibrations for 18F. For each radionuclide, 3 ml of stock solution was measured in two clinical geometries: a 10 ml glass vial and a 10 ml syringe. The initial activity was typically 100 MBq for 99mTc, 15 MBq for 111In and 115 MBq for 18F. The reference value for the massic activity of the radioactive solutions was determined by means of primary and secondary standardisation techniques at the radionuclide metrology laboratory of the JRC. The overall results of the intercomparison were satisfactory for 99mTc and 18F, since most radionuclide calibrators (>70%) were accurate within +/ 5% of the reference value. Nevertheless, some devices underestimated the activity by 10-20%. Conversely, 111In measurements were strongly affected by source geometry effects and this had a negative impact on the accuracy of the measurements, in particular for the syringe sample. Large overestimations (up to 72%) were observed, even when taking into account the corrections and uncertainties supplied by the manufacturers for container effects. The results of this exercise encourage the hospitals to perform corrective actions to improve the calibration of their devices where needed. PMID- 29472079 TI - Thermoluminescence dosimetry of the dose received by scrotum and testes in radiotherapy of rectal cancer, compared to the point doses calculated by 3D planning software. AB - PURPOSE: Radiation received by the testes in the course of radiotherapy for rectal cancer may cause oligospermia and azospermia. We sought to determine the dose to the scrotum and testes with thermoluminescence dosimetry (TLD), and compare it to the dose calculated by 3D planning software. METHODS: The TLDs were fixed to the scrotum in six points anteriorly and posteriorly in two fractions of radiotherapy. All patients received a 50-50.4 Gy total dose in prone position with 3D-planning. The average dose of TLD measurements was compared to the average of 6 relevant point doses calculated by the planning software. RESULTS: The mean scrotal dose of radiation in 33 patients as measured by TLD was 3.77 Gy (7.5% of the total prescribed dose), and the mean of point doses calculated by the planning software was 4.11 Gy (8.1% of the total dose), with no significant difference. A significant relationship was seen between the position of the inferior edge of the fields and the mean scrotal dose (P = .04). Also body mass index (BMI) was inversely related with the scrotal dose (P = .049). CONCLUSION: We found a dose of about 4 Gy received by the scrotum and testes from a total prescribed dose of 50 Gy in the radiotherapy of rectal carcinoma patients, with TLD measurements confirming testicular dose estimations by the planning software. This dose could be significantly harmful for spermatogenesis. Thus careful attention to the testicular dose in radiotherapy of rectal cancer for men desiring continued fertility is a necessity. PMID- 29472081 TI - Experimental optimisation of the X-ray energy in microbeam radiation therapy. AB - Microbeam radiation therapy has demonstrated superior normal tissue sparing properties compared to broadbeam radiation fields. The ratio of the microbeam peak dose to the valley dose (PVDR), which is dependent on the X-ray energy/spectrum and geometry, should be maximised for an optimal therapeutic ratio. Simulation studies in the literature report the optimal energy for MRT based on the PVDR. However, most of these studies have considered different microbeam geometries to that at the Imaging and Medical Beamline (50 MUm beam width with a spacing of 400 MUm). We present the first fully experimental investigation of the energy dependence of PVDR and microbeam penumbra. Using monochromatic X-ray energies in the range 40-120 keV the PVDR was shown to increase with increasing energy up to 100 keV before plateauing. PVDRs measured for pink beams were consistently higher than those for monochromatic energies similar or equivalent to the average energy of the spectrum. The highest PVDR was found for a pink beam average energy of 124 keV. Conversely, the microbeam penumbra decreased with increasing energy before plateauing for energies above 90 keV. The effect of bone on the PVDR was investigated at energies 60, 95 and 120 keV. At depths greater than 20 mm beyond the bone/water interface there was almost no effect on the PVDR. In conclusion, the optimal energy range for MRT at IMBL is 90-120 keV, however when considering the IMBL flux at different energies, a spectrum with 95 keV weighted average energy was found to be the best compromise. PMID- 29472080 TI - Patient-specific organ and effective dose estimates in pediatric oncology computed tomography. AB - PURPOSE: Estimate organ and effective doses from computed tomography scans of pediatric oncologic patients using patient-specific information. MATERIALS AND METHODS: With IRB approval patient-specific scan parameters and patient size obtained from DICOM images and vendor-provided dose monitoring application were obtained for a cross-sectional study of 1250 pediatric patients from 0 through 20 y-olds who underwent head, chest, abdomen-pelvis, or chest-abdomen-pelvis CT scans. Patients were categorized by age. Organ doses and effective doses were estimated using VirtualDoseTM CT based on patient-specific information, tube current modulation (TCM), and age-specific realistic phantoms. CTDIvol, DLP, and dose results were compared with those reported in the literature. RESULTS: CTDIvol and DLP varied widely as patient size varied. The 75th percentiles of CTDIvol and DLP were no greater than in the literature with the exception of head scans of 16-20 y-olds and of abdomen-pelvis scans of larger patients. Eye lens dose from a head scan was up to 69 mGy. Mean organ doses agreed with other studies at maximal difference of 38% for chest and 41% for abdomen-pelvis scans. Mean effective dose was generally higher for older patients. The highest effective doses were estimated for the 16-20 y-olds as: head 3.3 mSv, chest 4.1 mSv, abdomen-pelvis 10.0 mSv, chest-abdomen-pelvis 14.0 mSv. CONCLUSION: Patient specific organ and effective doses have been estimated for pediatric oncologic patients from <1 through 20 y-olds. The effect of TCM was successfully accounted for in the estimates. Output parameters varied with patient size. CTDIvol and DLP results are useful for future protocol optimization. PMID- 29472082 TI - On the use of a novel Ferrous Xylenol-orange gelatin dosimeter for HDR brachytherapy commissioning and quality assurance testing. AB - PURPOSE: To evaluate a commercially available Ferrous-Xylenol Orange-Gel (FXG) dosimeter (TrueViewTM) coupled with Optical-Computed Tomography (OCT) read out, for 3D dose verification in an Ir-192 superficial brachytherapy application. METHODS: Two identical polyethylene containers filled with gel from the same batch were used. One was irradiated with an 18 MeV electron field to examine the dose-response linearity and obtain a calibration curve. A flap surface applicator was attached to the other to simulate treatment of a skin lesion. The dose distribution in the experimental set up was calculated with the TG-43 and the model based dose calculation (MBCA) algorithms of a commercial treatment planning system (TPS), as well as Monte Carlo (MC) simulation using the MCNP code. Measured and calculated dose distributions were spatially registered and compared. RESULTS: Apart from a region close to the container's neck, where gel measurements exhibited an over-response relative to MC calculations (probably due to stray light perturbation), an excellent agreement was observed between measurements and simulations. More than 97% of points within the 10% isodose line (80 cGy) met the gamma index criteria established from uncertainty analysis (5%/2 mm). The corresponding passing rates for the comparison of experiment to calculations using the TG-43 and MBDCA options of the TPS were 57% and 92%, respectively. CONCLUSION: TrueViewTM is suitable for the quality assurance of demanding radiotherapy applications. Experimental results of this work confirm the advantage of the studied MBDCA over TG-43, expected from the improved account of scatter radiation in the treatment geometry. PMID- 29472083 TI - Quantifying the performance of two different types of commercial software programs for 3D patient dose reconstruction for prostate cancer patients: Machine log files vs. machine log files with EPID images. AB - We clarified the reconstructed 3D dose difference between two different commercial software programs (Mobius3D v2.0 and PerFRACTION v1.6.4). Five prostate cancer patients treated with IMRT (74 Gy/37 Fr) were studied. Log files and cine EPID images were acquired for each fraction. 3D patient dose was reconstructed using log files (Mobius3D) or log files with EPID imaging (PerFRACTION). The treatment planning dose was re-calculated on homogeneous and heterogeneous phantoms, and log files and cine EPID images were acquired. Measured doses were compared with the reconstructed point doses in the phantom. Next, we compared dosimetric metrics (mean dose for PTV, rectum, and bladder) calculated by Mobius3D and PerFRACTION for all fractions from five patients. Dose difference at isocenter between measurement and reconstructed dose for two software programs was within 3.0% in both homogeneous and heterogeneous phantoms. Moreover, the dose difference was larger using skip arc plan than that using full arc plan, especially for PerFRACTION (e.g., dose difference at isocenter for PerFRACTION: 0.34% for full arc plan vs. -4.50% for skip arc plan in patient 1). For patients, differences in dosimetric parameters were within 1% for almost all fractions. PerFRACTION had wider range of dose difference between first fraction and the other fractions than Mobius3D (e.g., maximum difference: 0.50% for Mobius3D vs. 1.85% for PerFRACTION), possibly because EPID may detect some types of MLC positioning errors such as miscalibration errors or mechanical backlash which cannot be detected by log files, or that EPID data might include image acquisition failure and image noise. PMID- 29472084 TI - Effect of image registration on 3D absorbed dose calculations in 177Lu-DOTATOC peptide receptor radionuclide therapy. AB - Peptide receptor radionuclide therapy (PRRT) is an effective MRT (molecular radiotherapy) treatment, which consists of multiple administrations of a radiopharmaceutical labelled with 177Lu or 90Y. Through sequential functional imaging a patient specific 3D dosimetry can be derived. Multiple scans should be previously co-registered to allow accurate absorbed dose calculations. The purpose of this study is to evaluate the impact of image registration algorithms on 3D absorbed dose calculation. A cohort of patients was extracted from the database of a clinical trial in PRRT. They were administered with a single administration of 177Lu-DOTATOC. All patients underwent 5 SPECT/CT sequential scans at 1 h, 4 h, 24 h, 40 h, 70 h post-injection that were subsequently registered using rigid and deformable algorithms. A similarity index was calculated to compare rigid and deformable registration algorithms. 3D absorbed dose calculation was carried out with the Raydose Monte Carlo code. The similarity analysis demonstrated the superiority of the deformable registrations (p < .001). Average absorbed dose to the kidneys calculated using rigid image registration was consistently lower than the average absorbed dose calculated using the deformable algorithm (90% of cases), with percentage differences in the range [-19; +4]%. Absorbed dose to lesions were also consistently lower (90% of cases) when calculated with rigid image registration with absorbed dose differences in the range [-67.2; 100.7]%. Deformable image registration had a significant role in calculating 3D absorbed dose to organs or lesions with volumes smaller than 100 mL. Image based 3D dosimetry for 177Lu-DOTATOC PRRT is significantly affected by the type of algorithm used to register sequential SPECT/CT scans.

AB - The purpose of this study was to evaluate and compare the accuracy of dose calculations in second check softwares (Diamond, IMSure, MuCheck, and RadCalc) against the Phillips Pinnacle3 treatment planning system. Eighteen previously treated patients' treatment planning files consisting of a total of 204 beams were exported from the Pinnacle3 TPS to each of the four second check software. Of these beams, 145 of the beams used were IMRT plans while 59 were VMAT arcs. The values were represented as a percent difference between primary and secondary calculations and used for statistical analysis. Box plots, Pearson Correlation, and Bland-Altman analysis were performed in MedCalc. The mean percent difference in calculated dose for Diamond, IMSure, MuCheck, and RadCalc from Pinnacle3 were 0.67%, 0.31%, 1.51% and -0.36%, respectively. The corresponding variances were calculated to be 0.07%, 0.13%, 0.08%, and 0.03%; and the largest percent differences were -7.9%, 9.70%, 9.39%, and 5.45%. The dose differences of each of the second check software in this study can vary considerably and VMAT plans have larger differences than IMRT. Among the four second check softwares, RadCalc values has shown a high agreement on average with low variation, and had the smallest percent range from Pinnacle3 values. The closest in average percent difference from the Pinnacle3data was the IMSure software, but suffered from significantly larger variance and percent range. The values reported by Diamond and MuCheck had significantly high percent differences with TPS values.

AB - In this study, qualities of 4D cone-beam CT (CBCT) images obtained using various gantry rotation speeds (GRSs) for liver stereotactic body radiation therapy (SBRT) with fiducial markers were quantitatively evaluated. Abdominal phantom containing a fiducial marker was moved along a sinusoidal waveform, and 4D-CBCT images were acquired with GRSs of 50-200 degrees min-1. We obtained the 4D-CBCT projection data from six patients who underwent liver SBRT and generated 4D-CBCT images at GRSs of 67-200 degrees min-1, by varying the number of projection data points. The image quality was evaluated based on the signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), and structural similarity index (SSIM). The fiducial marker positions with different GRSs were compared with the setup values and a reference position in the phantom and clinical studies, respectively. The root mean square errors (RMSEs) were calculated relative to the reference positions. In the phantom study, the mean SNR, CNR, and SSIM decreased from 37.6 to 10.1, from 39.8 to 10.1, and from 0.9 to 0.7, respectively, as the GRS increased from 50 to 200 degrees min-1. The fiducial marker positions were within 2.0 mm at all GRSs. Similarly, in the clinical study, the mean SNR, CNR, and SSIM decreased from 50.4 to 13.7, from 24.2 to 6.0, and from 0.92 to 0.73, respectively. The mean RMSEs were 2.0, 2.1, and 3.6 mm for the GRSs of 67, 100, and 200 degrees min-1, respectively. We conclude that GRSs of 67 and 85 degrees min-1 yield images of acceptable quality for 4D-CBCT in liver SBRT with fiducial markers. PMID- 29472087 TI - An assessment of a 3D EPID-based dosimetry system using conventional two- and three-dimensional detectors for VMAT. AB - PURPOSE: To provide a 3D dosimetric evaluation of a commercial portal dosimetry system using 2D/3D detectors under ideal conditions using VMAT. METHODS: A 2D ion chamber array, radiochromic film and gel dosimeter were utilised to provide a dosimetric evaluation of transit phantom and pre-treatment 'fluence' EPID back projected dose distributions for a standard VMAT plan. In-house 2D and 3D gamma methods compared pass statistics relative to each dosimeter and TPS dose distributions. RESULTS: Fluence mode and transit EPID dose distributions back projected onto phantom geometry produced 2D gamma pass rates in excess of 97% relative to other tested detectors and exported TPS dose planes when a 3%, 3 mm global gamma criterion was applied. Use of a gel dosimeter within a glass vial allowed comparison of measured 3D dose distributions versus EPID 3D dose and TPS calculated distributions. 3D gamma comparisons between modalities at 3%, 3 mm gave pass rates in excess of 92%. Use of fluence mode was indicative of transit results under ideal conditions with slightly reduced dose definition. CONCLUSIONS: 3D EPID back projected dose distributions were validated against detectors in both 2D and 3D. Cross validation of transit dose delivered to a patient is limited due to reasons of practicality and the tests presented are recommended as a guideline for 3D EPID dosimetry commissioning; allowing direct comparison between detector, TPS, fluence and transit modes. The results indicate achievable gamma scores for a complex VMAT plan in a homogenous phantom geometry and contributes to growing experience of 3D EPID dosimetry. PMID- 29472088 TI - Occupational exposures during abdominal fluoroscopically guided interventional procedures for different patient sizes - A Monte Carlo approach. AB - In this study we evaluated the occupational exposures during an abdominal fluoroscopically guided interventional radiology procedure. We investigated the relation between the Body Mass Index (BMI), of the patient, and the conversion coefficient values (CC) for a set of dosimetric quantities, used to assess the exposure risks of medical radiation workers. The study was performed using a set of male and female virtual anthropomorphic phantoms, of different body weights and sizes. In addition to these phantoms, a female and a male phantom, named FASH3 and MASH3 (reference virtual anthropomorphic phantoms), were also used to represent the medical radiation workers. The CC values, obtained as a function of the dose area product, were calculated for 87 exposure scenarios. In each exposure scenario, three phantoms, implemented in the MCNPX 2.7.0 code, were simultaneously used. These phantoms were utilized to represent a patient and medical radiation workers. The results showed that increasing the BMI of the patient, adjusted for each patient protocol, the CC values for medical radiation workers decrease. It is important to note that these results were obtained with fixed exposure parameters. PMID- 29472089 TI - Investigation of the XCAT phantom as a validation tool in cardiac MRI tracking algorithms. AB - PURPOSE: To describe our magnetic resonance imaging (MRI) simulated implementation of the 4D digital extended cardio torso (XCAT) phantom to validate our previously developed cardiac tracking techniques. Real-time tracking will play an important role in the non-invasive treatment of atrial fibrillation with MRI-guided radiosurgery. In addition, to show how quantifiable measures of tracking accuracy and patient-specific physiology could influence MRI tracking algorithm design. METHODS: Twenty virtual patients were subjected to simulated MRI scans that closely model the proposed real-world scenario to allow verification of the tracking technique's algorithm. The generated phantoms provide ground-truth motions which were compared to the target motions output from our tracking algorithm. The patient-specific tracking error, ep, was the 3D difference (vector length) between the ground-truth and algorithm trajectories. The tracking errors of two combinations of new tracking algorithm functions that were anticipated to improve tracking accuracy were studied. Additionally, the correlation of key physiological parameters with tracking accuracy was investigated. RESULTS: Our original cardiac tracking algorithm resulted in a mean tracking error of 3.7 +/- 0.6 mm over all virtual patients. The two combinations of tracking functions demonstrated comparable mean tracking errors however indicating that the optimal tracking algorithm may be patient-specific. CONCLUSIONS: Current and future MRI tracking strategies are likely to benefit from this virtual validation method since no time-resolved 4D ground-truth signal can currently be derived from purely image-based studies. PMID- 29472090 TI - Non-invasive characterization of coronary artery atherosclerotic plaque using dual energy CT: Explanation in ex-vivo samples. AB - PURPOSE: In this study non-calcified plaque composition is evaluated by Dual Energy CT (DECT). Energy Dispersive X-ray Spectroscopy (EDS) has been used to study the Plaque composition. An attempt has been made to explain the DECT results with EDS analysis. METHODS: Thirty-two ex-vivo human cadaver coronary artery samples were scanned by DECT and data was evaluated to calculate their effective atomic number and electron density (Zeff & rhoe) by inversion method. Result of DECT was compared with pathology to assess their differentiating capability. The EDS study was used to explain DECT outcome. RESULTS: DECT study was able to differentiate vulnerable plaque from stable with 87% accuracy (area under the curve (AUC):0.85 [95% confidence interval {CI}:0.73-0.98}] and Kappa Coefficient (KC):0.75 with respect to pathology. EDS revealed significant compositional difference in vulnerable and stable plaque at p < .05. The weight percentage of higher atomic number elements like F, Na, Mg, S, Si, P, Cl, K and Ca was found to be slightly more in vulnerable plaques as compared to a stable plaque. EDS also revealed a significantly increased weight percentage of nitrogen in stable plaques. CONCLUSIONS: The EDS results were able to explain the outcomes of DECT study. This study conclusively explains the physics of DECT as a tool to assess the nature of non-calcified plaques as vulnerable and stable. The method proposed in this study allows for differentiation between vulnerable and stable plaque using DECT. PMID- 29472091 TI - Assessment of the variation in CT scanner performance (image quality and Hounsfield units) with scan parameters, for image optimisation in radiotherapy treatment planning. AB - PURPOSE: To define a method and investigate how the adjustment of scan parameters affected the image quality and Hounsfield units (HUs) on a CT scanner used for radiotherapy treatment planning. A lack of similar investigations in the literature may be a contributing factor in the apparent reluctance to optimise radiotherapy CT protocols. METHOD: A Catphan phantom was used to assess how image quality on a Toshiba Aquilion LB scanner changed with scan parameters. Acquisition and reconstruction field-of-view (FOV), collimation, image slice thickness, effective mAs per rotation and reconstruction algorithm were varied. Changes were assessed for HUs of different materials, high contrast spatial resolution (HCSR), contrast-noise ratio (CNR), HU uniformity, scan direction low contrast and CT dose-index. RESULTS: CNR and HCSR varied most with reconstruction algorithm, reconstruction FOV and effective mAs. Collimation, but not image slice width, had a significant effect on CT dose-index with narrower collimation giving higher doses. Dose increased with effective mAs. Highest HU differences were seen when changing reconstruction algorithm: 56 HU for densities close to water and 117 HU for bone-like materials. Acquisition FOV affected the HUs but reconstruction FOV and effective mAs did not. CONCLUSIONS: All the scan parameters investigated affected the image quality metrics. Reconstruction algorithm, reconstruction FOV, collimation and effective mAs were most important. Reconstruction algorithm and acquisition FOV had significant effect on HU. The methodology is applicable to radiotherapy CT scanners when investigating image quality optimisation, prior to assessing the impact of scan protocol changes on clinical CT images and treatment plans. PMID- 29472092 TI - IEC 61331-1: A new setup for testing lead free X-ray protective clothing. AB - PURPOSE: Lead free protective clothing can create a higher part of secondary radiation (SR) than products that are based on lead. Hence, the attenuation properties may be downgraded. The international measuring standard IEC 61331 1:2014 declares the "inverse broad beam geometry" (IBG) as standard method, which has recently been modified to IBG* by the Physikalisch Technische Bundesanstalt (PTB). Because of the unspecific partial irradiation of the ionization chamber problems in the evaluation of lead equivalence values (LEVs) can occur. An alternative method proposed in this paper overcomes these problems. MATERIALS AND METHODS: The alternative setup "modified broad beam geometry" (BBG*) was tested and compared to the IBG* method by performing Monte Carlo simulations and radiation measurements including several lead-composite and lead-free protective materials. RESULTS: Simulations show a reduced collection efficiency of SR under IBG* whereas BBG* features a high degree of SR collection. Material samples with a high amount of SR can feature up to 8% higher LEVs compared to IBG*. For most of the currently salable materials the differences of BBG* vs IBG* amount to <3% (0.25 mm LEV) and <1% (0.50 mm LEV). In special cases the currently practiced method can lead to heavier protective clothings. CONCLUSIONS: The proposed BBG* setup meets the specifications of the IEC standard with respect to energy response and SR collection. The method should be implemented in the IEC standard. PMID- 29472093 TI - Image quality for radiotherapy CT simulators with different scanner bore size. AB - PURPOSE: We compare image quality parameters derived from phantom images taken on three commercially available radiotherapy CT simulators. To make an unbiased evaluation, we assured images were obtained with the same surface dose measured using XR-QA2 model GafChromicTM film placed at the imaging phantom surface for all three CT-simulators. METHODS: Radiotherapy CT simulators GE LS 16, Philips Brilliance Big Bore, and Toshiba Aquilion LB were compared in terms of spatial resolution, low contrast detectability, image uniformity, and contrast to noise ratio using CATPHAN-504 phantom, scanned with Head and Pelvis protocols. Dose was measured at phantom surface, with CT scans repeated until doses on all scanners were within 2%. RESULTS: In terms of spatial resolution, the GE simulator appears slightly better, while Philips CT images are superior in terms of SNR for both scanning protocols. The CNR results show that Philips CT images appear to be better, except for high Z material, while Toshiba appears to fit in between the two simulators. CONCLUSIONS: While the image quality parameters for three RT CT simulators show comparable results, the scanner bore size is of vital importance in various radiotherapy applications. Since the image quality is a function of a large number of confounding parameters, any loss in image quality due to scanner bore size could be compensated by the appropriate choice of scanning parameters, including the exposure and by balancing between the additional imaging dose to the patient and high image quality required in highly conformal RT techniques. PMID- 29472094 TI - Multi-institutional comparison of computer-based independent dose calculation for intensity modulated radiation therapy and volumetric modulated arc therapy. AB - PURPOSE: No multi-institutional studies of computer-based independent dose calculation have addressed the discrepancies among radiotherapy treatment planning systems (TPSs) and the verification programs for intensity modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT). We conducted a multi-institutional study to investigate whether +/-5% is a reasonable action level for independent dose calculation for IMRT/VMAT. METHODS: In total, 477 IMRT/VMAT plans for prostate or head and neck (H&N) malignancies were retrospectively analyzed using a modified Clarkson-based commercial verification program. The doses from the TPSs and verification programs were compared using the mean +/-1 standard deviation (SD). RESULTS: In the TPS calculated dose comparisons for prostate and H&N malignancies, the sliding window (SW) technique (-2.5 +/- 1.8% and -5.3 +/- 2.6%) showed greater negative systematic differences than the step-and-shoot (S&S) technique (-0.3 +/- 2.2% and -0.8 +/- 2.2%). The VMAT dose differences for prostate and H&N malignancies were 0.9 +/- 1.8% and 1.1 +/- 3.3%, respectively. The SDs were larger for the H&N plans than for the prostate plans in both IMRT and VMAT. Such plans including more out-of-field control points showed greater systematic differences and SDs. CONCLUSIONS: This study will help individual institutions to establish an action level for agreement between primary calculations and verification for IMRT/VMAT. A local dose difference of +/-5% at a point within the planning target volume (above -350 HU) may be a reasonable action level. PMID- 29472095 TI - Dosimetric evaluation of modern radiation therapy techniques for left breast in deep-inspiration breath-hold. AB - PURPOSE: The dosimetric differences between four radiation therapy techniques for left sided whole breast irradiation were evaluated side by side in the same patient population. METHODS: Radiotherapy treatment plans were retrospectively created with Accuray TomoDirect (TD), Elekta Volumetric Modulated Arc Therapy (E VMAT), Varian RapidArc (RA) and Field-in-field (FinF) technique for 20 patients, who had received left breast irradiation during deep-inspiration breath-hold. Dose characteristics of planning target volume and organs at risk were compared. RESULTS: The E-VMAT, TD and RA treatment plans had higher target coverage (V95%) than FinF plans (97.7-98.3% vs. 96.6%). The low-dose spillage to contralateral breast and lung was smaller with FinF and TD (mean 0.1 and 0.3 Gy) compared to E VMAT and RA (mean 0.6 and 0.9 Gy). E-VMAT, RA and TD techniques were more effective than FinF in sparing left anterior descending artery (mean 4.0, 4.2 and 4.7 Gy vs. 6.1 Gy, respectively). CONCLUSIONS: In whole breast irradiation TD, E VMAT and RA plans generated in this study achieved higher dose coverage and sparing of organs from the high dose in the vicinity of the PTV. The advantage of calculated FinF plans is the lowest dose on contralateral organs. The choice of the technique used should be weighted by each institution taking into account the dose characteristics of each technique and its fit with patient anatomy bearing in mind the increased workload of using modulated techniques and the increased beam on time. PMID- 29472096 TI - Prediction of GTV median dose differences eases Monte Carlo re-prescription in lung SBRT. AB - BACKGROUND AND PURPOSE: The use of Monte Carlo (MC) dose calculation algorithm for lung patients treated with stereotactic body radiotherapy (SBRT) can be challenging. Prescription in low density media and time-consuming optimization conducted CyberKnife centers to propose an equivalent path length (EPL)-to-MC re prescription method based on GTV median dose. Unknown at the time of planning, GTV D50% practical application remains difficult. The current study aims at creating a re-prescription predictive model in order to limit conflicting dose value during EPL optimization. MATERIAL AND METHODS: 129 patients planned with EPL algorithm were recalculated with MC. Relative GTV_D50% discrepancies were assessed and influencing parameters identified using wrapper feature selection. Based on best descriptive parameters, predictive nomogram was built from multivariate linear regression. EPL-to-MC OARs near max-dose discrepancies were reported. RESULTS: The differences in GTV_D50% (median 10%, SD: 9%) between MC and EPL were significantly (p < .001) impacted by the lesion's surface-to-volume ratio and the average relative electronic density of the GTV and the GTV's 15 mm shell. Built upon those parameters, a nomogram (R2 = 0.79, SE = 4%) predicting the GTV_D50% discrepancies was created. Furthermore EPL-to-MC OAR dose tolerance limit showed a strong linear correlation with coefficient range [0.84-0.99]. CONCLUSION: Good prediction on the required re-prescription can be achieved prior planning using our nomogram. Based on strong linear correlation between EPL and MC for OARs near max-dose, further restriction on dose constraints during the EPL optimization can be warranted. This a priori knowledge eases the re-prescription process in limiting conflicting dose value. PMID- 29472098 TI - Comparison of relative renal functions calculated with 99mTc-DTPA and 99mTc-DMSA for kidney patients of wide age ranges. AB - Renal scintigraphy is an imaging method that uses small amount of radioactive materials called radiotracers, a Gamma camera and a computer to evaluate kidney functions and its anatomy. The present work reports the comparison of the relative renal functions (RRF) calculated with technetium-99m dimercaptosuccinic acid (99mTc-DMSA) and technetium-99m diethylenetriaminepentaacetic acid (99mTc DTPA) for kidney patients of ages between 5 months and 71 years. A total of 50 patients including 29 male and 21 female has been selected and studied for renography. The mean RRFs have been found to be 52.68 +/- 23.63% and 47.32 +/- 23.63% respectively for the left and right kidneys with 99mTc-DMSA measurement. With 99mTc-DTPA the values are 52.74 +/- 23.54% and 47.26 +/- 23.54% for the same. In bivariate correlation analysis, a significant positive correlation (r = 0.996, P < .001) has been found between the RRFs calculated with the two methods. Following the patients' diagnosis, in ANOVA test, no difference has been found between the RRFs calculated for the left and right kidneys. In Bland-Altman plots, the mean difference between the two methods has been found to be 0.1 and the correlation limit lies between -4.3 and 4.2. According to the result obtained in the present work, both the 99mTc-DMSA and 99mTc-DTPA scanning methods provide almost the same RRF values. It is, therefore, always not necessary to calculate the RRFs with both the methods. This study suggests that 99mTc-DMSA may be the primary choice for the evaluation of RRF, but if the glomerular filtration rate (GFR) and renogram curve are required, 99mTc-DTPA can be the obvious selection. PMID- 29472097 TI - The influence of the image registration method on the adaptive radiotherapy. A proof of the principle in a selected case of prostate IMRT. AB - PURPOSE: To analyse the influence of the image registration method on the adaptive radiotherapy of an IMRT prostate treatment, and to compare the dose accumulation according to 3 different image registration methods with the planned dose. MATERIAL AND METHODS: The IMRT prostate patient was CT imaged 3 times throughout his treatment. The prostate, PTV, rectum and bladder were segmented on each CT. A Rigid, a deformable (DIR) B-spline and a DIR with landmarks registration algorithms were employed. The difference between the accumulated doses and planned doses were evaluated by the gamma index. The Dice coefficient and Hausdorff distance was used to evaluate the overlap between volumes, to quantify the quality of the registration. RESULTS: When comparing adaptive vs no adaptive RT, the gamma index calculation showed large differences depending on the image registration method (as much as 87.6% in the case of DIR B-spline). The quality of the registration was evaluated using an index such as the Dice coefficient. This showed that the best result was obtained with DIR with landmarks compared with the rest and it was always above 0.77, reported as a recommended minimum value for prostate studies in a multi-centre review. CONCLUSIONS: Apart from showing the importance of the application of an adaptive RT protocol in a particular treatment, this work shows that the election of the registration method is decisive in the result of the adaptive radiotherapy and dose accumulation. PMID- 29472099 TI - Neurotransmitter activity is linked to outcome following subthalamic deep brain stimulation in Parkinson's disease. AB - INTRODUCTION: While the mechanisms underlying the therapeutic effects of deep brain stimulation (DBS) in Parkinson's Disease (PD) are not yet fully understood, DBS appears to exert a wide range of neurochemical effects on the network level, thought to arise from activation of inhibitory and excitatory pathways. The activity within the primary inhibitory (GABAergic) and excitatory (glutamatergic) neurotransmitter systems may therefore play an important role in the therapeutic efficacy of DBS in PD. The purpose of this study was to investigate abnormalities in GABA-ergic and glutamatergic neurotransmission in PD, and to examine the link between neurotransmitter levels and outcome following DBS. METHODS: Magnetic resonance spectra were acquired from the pons and basal ganglia in sixteen patients with PD and sixteen matched control participants. GABA and glutamate levels were quantified with LCModel, an automated spectral fitting package. Fourteen patients subsequently underwent DBS, and PD symptoms were evaluated with the MDS-UPDRS at baseline and six months after surgery. The efficacy of DBS treatment was evaluated from the percentage improvement in MDS-UPDRS scores. RESULTS: Basal ganglia GABA levels were significantly higher in PD patients relative to control participants (p < 0.01), while pontine glutamate + glutamine (Glx) levels were significantly lower in patients with PD (p < 0.05). While GABA levels were not significantly related to outcome post-surgery, basal ganglia glutamate levels emerged as a significant predictor of outcome, suggesting a possible role for glutamatergic neurotransmission in the therapeutic mechanism of DBS. CONCLUSION: GABAergic and glutamatergic neurotransmission is altered in PD, and glutamatergic activity in particular may influence outcome post-surgery.

PMID- 29472102 TI - Modeling human pancreatic beta cell dedifferentiation. AB - OBJECTIVE: Dedifferentiation could explain reduced functional pancreatic beta cell mass in type 2 diabetes (T2D). METHODS: Here we model human beta-cell dedifferentiation using growth factor stimulation in the human beta-cell line, EndoC-betaH1, and human pancreatic islets. RESULTS: Fibroblast growth factor 2 (FGF2) treatment reduced expression of beta-cell markers, (INS, MAFB, SLC2A2, SLC30A8, and GCK) and activated ectopic expression of MYC, HES1, SOX9, and NEUROG3. FGF2-induced dedifferentiation was time- and dose-dependent and reversible upon wash-out. Furthermore, FGF2 treatment induced expression of TNFRSF11B, a decoy receptor for RANKL and protected beta-cells against RANKL signaling. Finally, analyses of transcriptomic data revealed increased FGF2 expression in ductal, endothelial, and stellate cells in pancreas from T2D patients, whereas FGFR1, SOX,9 and HES1 expression increased in islets from T2D patients. CONCLUSIONS: We thus developed an FGF2-induced model of human beta-cell dedifferentiation, identified new markers of dedifferentiation, and found evidence for increased pancreatic FGF2, FGFR1, and beta-cell dedifferentiation in T2D.

AB - BACKGROUND: The objective of the current study was to define risk factors associated with the 30-day post-operative risk of VTE after HPB surgery and create a model to identify patients at highest risk of post-discharge VTE. METHODS: Patients who underwent hepatectomy or pancreatectomy in the ACS-NSQIP Participant Use Files 2011-2015 were identified. Logistic regression modeling was used; a model to predict post-discharge VTE was developed. Model discrimination was tested using area under the curve (AUC). RESULTS: Among 48,860 patients, the overall 30-day incidence of VTE after hepatectomy and pancreatectomy was 3.2% (n = 1580) with 1.1% (n = 543) of VTE events occurring after discharge. Patients who developed post-discharge VTE were more likely to be white, had a higher median BMI, have undergone pancreatic surgery, had longer median operative times, and to have had a transfusion. A weighted prediction model demonstrated good calibration and fair discrimination (AUC = 0.63). A score of >=-4.50 had maximum sensitivity and specificity, resulting in 44% of patients being treating with prophylaxis for an overall VTE risk of 1.1%. CONCLUSIONS: Utilizing independent factors associated with post-discharge VTE, a prediction model was able to stratify patients according to risk of VTE and may help identify patients who are most likely to benefit from pharmacoprophylaxis. PMID- 29472103 TI - p204 Is Required for Canonical Lipopolysaccharide-induced TLR4 Signaling in Mice. AB - p204, a murine member of an interferon-inducible p200 family, was reported to recognize intracellular viral and bacterial DNAs, however, its role in the innate immunity in vivo remains unknown due to the lack of p204-deficient animal models. In this study we first generated the p204-/- mice. Unexpectedly, p204 deficiency led to significant defect in extracellular LPS signaling in macrophages, as demonstrated by dramatic reductions of LPS-mediated IFN-beta and pro-inflammatory cytokines. The serum levels of IFN-beta and pro-inflammatory cytokines were also significantly reduced in p204-/- mice following LPS challenge. In addition, p204 /- mice were resistant to LPS-induced shock. LPS-activated NF-KB and IRF-3 pathways were all defective in p204-deficient macrophages. p204 binds to TLR4 through its Pyrin domain, and it is required for the dimerization of TLR4 following LPS-challenge. Collectively, p204 is a critical component of canonical LPS-TLR4 signaling pathway, and these studies also suggest that p204 could be a potential target to prevent and treat inflammatory and infectious diseases. PMID- 29472106 TI - Open versus laparoscopic portal lymphadenectomy in gallbladder cancer: is there a difference in lymph node yield? AB - BACKGROUND: Gallbladder cancer (GBC) is the most common biliary tract malignancy. Because it commonly metastasizes via lymphatics, portal lymphadenectomy should be included in oncologic resections. This study aimed to compare the oncologic equivalence of the laparoscopic versus open technique by evaluating lymph node (LN) yield. METHODS: The 2010-2012 National Cancer Data Base identified patients who underwent laparoscopic or open resection of GBC with dedicated lymphadenectomy. LN yield was compared by resection method. Variables associated with LN yield >=3 were identified. RESULTS: Of 1524 patients identified, 52% were intended to undergo laparoscopic surgery, with 20% of these patients converted to open. Collection of >=3 LNs following open resection (47%) was higher than for laparoscopic resection (34%), p < 0.001. Operations performed at high-volume (aOR:1.74, p < 0.001) and/or academic centers (aOR:1.70, p = 0.024) had superior LN yield. LN yield was not associated with overall survival (aHR:0.93, p = 0.493). CONCLUSIONS: In this analysis of national data, LN yield following laparoscopic resection for GBC was significantly lower than following open resection. Open resection is more frequently performed at academic centers, possibly to assure adequate oncologic resection. Enforcing consensus guidelines for lymphadenectomy in gallbladder cancer will optimize outcomes as minimally invasive approaches evolve. PMID- 29472107 TI - Are antimicrobial stewardship programs effective strategies for preventing antibiotic resistance? A systematic review. AB - BACKGROUND: Antimicrobial stewardship programs (ASPs) have been proposed as a solution for the global burden of antibiotic resistance, despite the lack of evidence on the subject. OBJECTIVE: To analyze the role of ASPs in reducing bacterial resistance to antibiotics in hospital settings. DATA SOURCES: A review in PubMed, Scopus, LILACS, and SciELO databases was performed. The period analyzed was January 1, 2012-January 4, 2017. ELIGIBILITY CRITERIA: Studies that related ASPs to bacterial resistance. DATA EXTRACTION: All studies that did not focus on ASPs were removed. Antifungal and antiviral programs were excluded. RESULTS: Only 8 studies had quasi-experimental designs, and none were controlled trials. ASP strategies and microorganism-antibiotic pairs evaluated varied widely. Seven studies were classified as presenting clearly positive results, 3 had limited positive results, 7 had doubtful results, 4 had negative results, and 5 had noninterpretable results. The implementation of new infection control practices occurred in 7 studies. LIMITATIONS: There are yet few studies on this matter, and most of them have inadequate study designs. Great heterogeneity between study features was detrimental to drawing evidence-based conclusions. CONCLUSIONS: There is no solid evidence that ASPs are effective in reducing antibiotic resistance in hospital settings. We uphold the need for more studies with appropriate study designs, standardized ASP interventions targeting common microorganism-antibiotic pairs, and avoiding simultaneous implementation of infection control practices. PMID- 29472108 TI - Pediatric issues in thrombosis and hemostasis: The how and why of venous thromboembolism risk stratification in hospitalized children. AB - Multiple observational studies have identified risk factors for venous thromboembolism (VTE) in hospitalized children, but very few interventional studies have assessed the safety and efficacy of thromboprophylaxis in this population. In recent years, however, evidence in pediatric VTE risk stratification has grown considerably. This has led to the conception of a pediatric subpopulation-specific risk-based paradigm for mechanical and pharmacological thromboprophylaxis in hospitalized children. More research is required to validate and further refine pediatric subpopulation-specific risk models and to subsequently investigate risk-stratified thromboprophylaxis strategies for hospitalized children. PMID- 29472109 TI - Bradycardia: What is the mechanism? PMID- 29472110 TI - Experimental confirmation of a character-facing bias in literacy development. AB - When learning to write, children often mirror-reverse individual letters. For children learning to use the Latin alphabet, in a left-to-right writing culture, letters that appear to face left (such as J and Z) seem to be more prone to reversal than those that appear to face right (such as B and C). It has been proposed that, because most asymmetrical Latin letters face right, children statistically learn this general regularity and are subsequently biased to write any letter rightward. The evidence for this character-facing bias is circumstantial, however, because letter-facing direction is confounded with other factors that could affect error rates; for instance, J and Z are left-facing, but they are also infrequent. We report the first controlled experimental test of the character-facing bias. We taught 43 Scottish primary schoolchildren (aged 4.8-5.8 years) four artificial, letter-like characters, two of which were left-facing and two of which were right-facing. The characters were novel and so were not subject to prior exposure effects, and alternate groups of children were assigned to identical but mirror-reflected character sets. Children were three times more likely to mirror-write a novel character they had learned in a left-facing format than to mirror-write one they had learned in a right-facing format. This provides the first experimental confirmation of the character-facing bias in literacy development and suggests that implicit knowledge acquired from exposure to written language is readily generalized to novel letter-like forms.

The objective of this study is to ascertain its frequency and characteristics in the northern area of the autonomous community of Castile and Leon. METHODS: A retrospective study of patients with MAC isolates in respiratory samples from five public hospitals in the autonomous community over a six-year period, following the ATS/IDSA criteria. The MAC strains were identified by GenoType Mycobacterium reverse hybridisation probes or PCR-RFLP analysis of the hsp65 gene. RESULTS: Of 183 cases of MAC identified, only five women (2.7%) aged 68.8+/-10.7years met LWS criteria. In three cases, MAC was isolated jointly and intermittently with other pathogens. Only one patient was treated according to ATS/IDSA criteria. DISCUSSION: LWS remains underestimated, with affected patients representing a significant burden on healthcare resources over long periods of time. As a result, greater microbiological and therapeutic knowledge of the syndrome is needed. PMID- 29472112 TI - Abnormal Heavy/Light Chain Ratio and Matched Pair Suppression Increase Residual Disease Detection Sensitivity in Patients With Multiple Myeloma With Deep Responses. AB - BACKGROUND: Heavy/light chain (HLC) assay can quantify involved as well as uninvolved immunoglobulin pairs and is used to detect monoclonal proteins. PATIENTS AND METHODS: We compared the sensitivity between HLC assay and serum protein electrophoresis, serum immunofixation electrophoresis (IFE), and free light chain (FLC) assay in patients with symptomatic multiple myeloma (n = 111) whose responses were stable disease or better. RESULTS: Among patients with negative IFE and normal FLC ratios, 84.4% (38 of 45) and 80% (36 of 45) exhibited normal HLC ratios and no pair suppression, respectively (13.3% [6 of 45], moderate pair suppression and 6.7% [3 of 45], severe pair suppression). The lower the monoclonal protein levels, the more the possibility that the patients had normal HLC ratios and no matched pair suppression (both P < .000001). HLC ratios or pair suppression combined with IFE results and FLC ratios were more sensitive for detecting monoclonal proteins than were IFE results and FLC ratios alone (P = .016 and .0039, respectively). A combination of all 4 methods (IFE, FLC, HLC, and pair suppression) was far more sensitive than were IFE findings plus FLC ratios alone (P = .00024). CONCLUSION: Abnormal HLC ratios and HLC-matched pair suppression can increase the sensitivity for detecting residual disease in patients with multiple myeloma with deep responses.

AB - The use of ultrasound in differentiation of benign and malignant solid hypo echoic thyroid nodules is a dilemma in clinical practice. The aim of this study was to investigate the revised value of contrast-enhanced ultrasound (CEUS) for differentiating solid hypo-echoic thyroid nodules using the Thyroid Imaging Reporting and Data System (TI-RADS).The study included 135 patients with 135 nodules confirmed by fine-needle aspiration and/or surgery. Every nodule underwent both conventional US and CEUS. Binary logistic regression analysis for conventional US features revealed that irregular shape, microcalcification and height greater than width were significant malignant predictive features. Binary logistic analysis for CEUS features indicated that hetero-enhancement, slow wash in, an ill-defined enhancement border and fast wash-out were significantly associated with malignancy. The areas under the curve of the TI-RADS, CEUS and the combination were 0.806, 0.934 and 0.950, respectively. CEUS is a potentially useful tool in the differentiation of solid hypo-echoic thyroid nodules. PMID- 29472114 TI - Enlarged Size and Impaired Elastic Properties of the Ascending Aorta are Associated with Endothelial Dysfunction and Elevated Plasma Matrix Metalloproteinase-2 Level in Patients with Bicuspid Aortic Valve. AB - The aim of this study was to test whether enlarged size and impaired elastic properties of the ascending aorta are associated with impaired endothelial function and increases in plasma matrix metalloproteinase (MMP)-2 concentrations in patients with bicuspid aortic valve (BAV) without significant valvular dysfunction. The size and the elasticity of the ascending aorta and the flow mediated vasodilation (FMD) in the brachial artery in response to hyperemia were evaluated with 2-D echocardiography and high-frequency linear ultrasound in 42 patients with BAV without significant valvular dysfunction and 30 age- and sex matched healthy controls. In the BAV group, diastolic ascending aortic diameter (AoD) (32.1 +/- 8.1 mm vs. 25.3 +/- 3.6 mm, p <0.001) and aortic stiffness index (8.0 +/- 5.3 vs. 4.0 +/- 1.8, p <0.001) were significantly higher, and aortic strain (7.4 +/- 3.6% vs. 11.1 +/- 3.0%, p <0.001) and aortic distensibility (7.4 +/- 4.1 * 10-6cm2/dyn vs. 11.1 +/- 4.3 * 10-6cm2/dyn, p <0.001) were significantly lower than those in the control group. The BAV group also had lower FMD (6.5 +/- 2.2% vs. 11.9 +/- 2.7%, p <0.001) and higher plasma MMP-2 levels (226.7 +/- 55.0 ng/mL vs. 177.0 +/- 45.3 ng/mL, p <0.001) compared with the control group. In the BAV group, AoD, aortic strain, aortic stiffness index and aortic distensibility significantly correlated with FMD and MMP-2 (all p <0.05). The multivariable linear regression analysis further indicated that FMD and MMP-2 were independently associated with AoD (beta = -1.1, p = 0.005, and beta = 0.09, p <0.001, respectively). These findings suggest that enlarged size and impaired elastic properties of the ascending aorta are associated with endothelial dysfunction and elevated plasma MMP-2 level in patients with BAV without significant valvular dysfunction. FMD and plasma MMP-2 level are the significant and independent predictors of dilation of the ascending aorta in patients with BAV. PMID- 29472115 TI - CT colonography provides new insights into interval cancers. PMID- 29472116 TI - Post-imaging colorectal cancer or interval cancer rates after CT colonography: a systematic review and meta-analysis. AB - BACKGROUND: CT colonography is highly sensitive for colorectal cancer, but interval or post-imaging colorectal cancer rates (diagnosis of cancer after initial negative CT colonography) are unknown, as are their underlying causes. We did a systematic review and meta-analysis of post-CT colonography and post imaging colorectal cancer rates and causes to address this gap in understanding. METHODS: We systematically searched MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials. We included randomised, cohort, cross-sectional, or case-control studies published between Jan 1, 1994, and Feb 28, 2017, using CT colonography done according to international consensus standards with the aim of detecting cancer or polyps, and reporting post-imaging colorectal cancer rates or sufficient data to allow their calculation. We excluded studies in which all CT colonographies were done because of incomplete colonoscopy or if CT colonography was done with knowledge of colonoscopy findings. We contacted authors of component studies for additional data where necessary for retrospective CT colonography image review and causes for each post-imaging colorectal cancer. Two independent reviewers extracted data from the study reports. Our primary outcome was prevalence of post-imaging colorectal cancer 36 months after CT colonography. We used random-effects meta-analysis to estimate pooled post-imaging colorectal cancer rates, expressed using the total number of cancers and total number of CT colonographies as denominators, and per 1000 person-years. This study is registered with PROSPERO, number CRD42016042437. FINDINGS: 2977 articles were screened and 12 studies were eligible for analysis. These studies reported data for 19 867 patients (aged 18-96 years; of 11 590 with sex data available, 6532 [56%] were female) between March, 2002, and May, 2015. At a mean of 34 months' follow-up (range 3-128.4 months), CT colonography detected 643 colorectal cancers. 29 post-imaging colorectal cancers were subsequently diagnosed. The pooled post-imaging colorectal cancer rate was 4.42 (95% CI 3.03-6.42) per 100 cancers detected, corresponding to 1.61 (1.11-2.33) post-imaging colorectal cancers per 1000 CT colonographies or 0.64 (0.44-0.92) post-imaging colorectal cancers per 1000 person-years. Heterogeneity was low (I2=0%). 17 (61%) of 28 post imaging colorectal cancers were attributable to perceptual error and were visible in retrospect. INTERPRETATION: CT colonography does not lead to an excess of post test cancers relative to colonoscopy within 3-5 years, and the low 5-year post imaging colorectal cancer rate confirms that the recommended screening interval of 5 years is safe. Since most post-imaging colorectal cancers arise from perceptual errors, radiologist training and quality assurance could help to reduce post-imaging colorectal cancer rates.

PMID- 29472117 TI - DNA methylation signature in blood does not predict calendar age in patients with chronic lymphocytic leukemia but may alert to the presence of disease. PMID- 29472118 TI - Loss of heterozygosity of MIR15A/MIR16-1, negative regulators of the antiapoptotic gene BCL2, is not common in odontogenic keratocysts. AB - OBJECTIVES: The odontogenic keratocyst (OKC) is an aggressive odontogenic cyst that has a high recurrence rate. Apart from PTCH1 mutations, few molecular alterations are described in OKCs. Low expression of microRNAs (miRNAs) miR-15a and/or miR-16-1 in association with increased expression of their target, Bcl-2, have been previously found in OKC. In humans, MIR15A and MIR16-1 are clustered at chromosome position 13 q14, and loss of heterozygosity (LOH) at this locus occurs in different tumors. We aimed to determine whether deletion at 13 q14 is a potential mechanism leading to miR-15a/16-1 aberrant expression in OKC. METHODS: Genomic DNA was extracted from 15 formalin-fixed, paraffin-embedded microdissected OKC cases. The polymorphic DNA markers D13S272 and D13S273 on chromosome 13 q14.3, around MIR15A/MIR16-1, were amplified by polymerase chain reaction. LOH was examined by capillary electrophoresis DNA-fragment analysis. RESULTS: The D13S272 marker had no LOH in 12 informative cases, whereas 2 out of 9 informative cases (22%) had LOH at the D13S273 marker. CONCLUSIONS: An LOH event at MIR15A/MIR16-1 locus is not common in OKC. The mechanism underlying the regulation of miR-15a and miR-16-1 expression in OKC remains to be determined. PMID- 29472119 TI - Dupilumab treatment in moderate-to-severe atopic dermatitis: A systematic review and meta-analysis. AB - BACKGROUND: Dupilumab, a fully human monoclonal antibody against the interleukin 4-receptor alpha subunit, has been developed and used in clinical trials to treat atopic dermatitis (AD). OBJECTIVE: We aimed to assess the overall efficacy and safety of dupilumab treatment in AD. METHODS: PubMed, Embase, Cochrane library databases, and the Chinese Biological Medicine (CBM) published up to September 2017 were searched. All randomized controlled trials (RCTs) of dupilumab treatment on adult patients with AD were included. Fixed- or random-effects models were used to calculate pooled standard mean differences or relative risks (SMD or RR, respectively). RESULTS: Six trials involving 2447 patients were identified. Pooled analysis revealed significant improvements in Eczema Area and Severity Index (EASI) score (SMD = -0.89, 95% CI: -1.0 to -0.78), percentage of body surface area (BSA) (SMD = -0.83, 95% CI: -0.90 to -0.75), pruritus numeric rating scale (NRS) scores (SMD = -0.81, 95% CI: -0.96 to -0.66), and Dermatology Life Quality Index (DLQI) scores (SMD = -0.78, 95% CI: -0.89 to -0.66). Dupilumab treatment was also associated with a significant increase in the proportion of patients achieving Investigator's Global Assessment (IGA) response (RR = 3.82; 95% CI: 3.23 to 4.51) and a similar incidence of adverse events (RR = 1.0; 95% CI: 0.96 to 1.04). CONCLUSIONS: Our analysis provided evidence that dupilumab had an acceptable safety profile and resulted in clinically relevant improvements in signs and symptoms of AD. Dose regimens of 300 mg qw and q2 w seemed to have similar benefits. Further long-term trials are required for confirmation. PMID- 29472120 TI - Targeting CD6 for the treatment of experimental autoimmune uveitis. AB - OBJECTIVE: CD6 is emerging as a new target for treating many pathological conditions in which T cells are integrally involved, but even the latest data from studies of CD6 gene engineered mice were still contradictory. To address this issue, we studied experimental autoimmune uveitis (EAU), a model of autoimmune uveitis, in wild-type (WT) and CD6 knockout (KO) mice. METHODS: After EAU induction in WT and CD6 KO mice, we evaluated ocular inflammation and compared retinal antigen-specific T-cell responses using scanning laser ophthalmoscopy, spectral-domain optical coherence tomography, histopathology, and T cell recall assays. Uveitogenic T cells from WT and CD6 KO mice were adoptively transferred into WT naive mice to confirm the impact of CD6 on T cells. In addition, we immunized CD6 KO mice with recombinant CD6 protein to develop mouse anti-mouse CD6 monoclonal antibodies (mAbs) in which functional antibodies exhibiting cross-reactivity with human CD6 were screened and identified for treatment studies. RESULTS: In CD6 KO mice with EAU, we found significantly decreased retinal inflammation and reduced autoreactive T-cell responses, and confirmed the impaired uveitogenic capacity of T cells from these mice in an adoptive transfer experiment. Notably, one of these cross-reactive mAbs significantly ameliorated retinal inflammation in EAU induced by the adoptive transfer of uveitogenic T cells. CONCLUSIONS: Together, these data strongly suggest that CD6 plays a previously unknown, but pivotal role in autoimmune uveitis, and may be a promising new treatment target for this blinding disease. In addition, the newly developed mouse anti-mouse/human CD6 mAbs could be valuable tools for testing CD6-targeted therapies in other mouse models of human diseases. PMID- 29472121 TI - The relationship between energy intake and body-growth in children with cystic fibrosis. AB - BACKGROUND & AIMS: Body-growth, expressed as weight- and height gain, is a strong predictor of morbidity and mortality in patients with cystic fibrosis (CF). Whether current historically based recommendations on a high-energy diet are sufficient for optimal growth is questionable. We therefore assessed the longitudinal relation between body-growth and routine energy intake in paediatric CF patients. METHODS: Included were patients with CF, aged 2-10 years of whom we obtained 969 measurements of weight and height along with dietary records, and 786 coefficient of fat absorption measurements (CFA). We described body-growth, energy intake, macronutrient intake and the long-term effect of energy intake and coefficient of fat absorption on body-growth during the 8-year follow-up period. RESULTS: Enrolled were 191 children with CF who had a compromised growth when compared to healthy children. The dietary intake was >=110% estimated average requirement (EAR) in 47% of the measurements (457/969) and did not (fully) achieve the recommended high-energy level (110-200% EAR). Further, the intake expressed as EAR decreased with increasing age. Cross-sectionally, boys and girls with higher caloric intakes had higher weight-for-age (WFA). The caloric intake explained 18 and 6% of the variation. Further, boys with higher caloric intakes had also higher height-for-age-adjusted-for-target-height (HFA/TH) or BMI. The caloric intake explained 6 or 7% of the variation. Longitudinally, caloric intake was associated with both WFA in boys and girls, and with BMI in boys. Each 100 calories increased intake would result in a 0.01 (girls)-0.02 increase in z-score WFA and 0.03 increase in z-score BMI. We found no significant association between CFA and WFA, HFA/TH or BMI. The contribution of protein, fat and carbohydrates was not associated with WFA, nor with HFA/TH or BMI. CONCLUSION: Even at this relatively early age, a compromised growth in children with CF was found when compared to healthy children. The energy intake was below 110% EAR in 47% of the measurements, and appeared to be insufficient to prevent suboptimal body-growth over the 8-years of follow-up. PMID- 29472122 TI - Recent developments of downstream processing for microbial lipids and conversion to biodiesel. AB - With increasing global population and depleting resources, there is an apparent demand for radical unprecedented innovation to satisfy the basal needs of lives. Hence, non-conventional renewable energy resources like biodiesel have been worked out in past few decades. Biofuel (e.g. Biodiesel) serves to be the most sustainable answer to solve "food vs. fuel crisis". In biorefinery process, lipid extraction from oleaginous microbial lipids is an integral part as it facilitates the release of fatty acids. Direct lipid extraction from wet cell-biomass is favorable in comparison to dry-cell biomass because it eliminates the application of expensive dehydration. However, this process is not commercialized yet, instead, it requires intensive research and development in order to establish robust approaches for lipid extraction that can be practically applied on an industrial scale. This review aims for the critical presentation on cell disruption, lipid recovery and purification to support extraction from wet cell biomass for an efficient transesterification. PMID- 29472123 TI - Can algae-based technologies be an affordable green process for biofuel production and wastewater remediation? AB - Algae is a well-known organism that its characteristic is prominent for biofuel production and wastewater remediation. This critical review aims to present the applicability of algae with in-depth discussion regarding three key aspects: (i) characterization of algae for its applications; (ii) the technical approaches and their strengths and drawbacks; and (iii) future perspectives of algae-based technologies. The process optimization and combinations with other chemical and biological processes have generated efficiency, in which bio-oil yield is up to 41.1%. Through life cycle assessment, algae bio-energy achieves high energy return than fossil fuel. Thus, the algae-based technologies can reasonably be considered as green approaches. Although selling price of algae bio-oil is still high (about $2 L-1) compared to fossil fuel's price of $1 L-1, it is expected that the algae bio-oil's price will become acceptable in the next coming decades and potentially dominate 75% of the market. PMID- 29472125 TI - Discovery of isatin and 1H-indazol-3-ol derivatives as d-amino acid oxidase (DAAO) inhibitors. AB - d-Amino acid oxidase (DAAO) is a potential target in the treatment of schizophrenia as its inhibition increases brain d-serine level and thus contributes to NMDA receptor activation. Inhibitors of DAAO were sought testing [6+5] type heterocycles and identified isatin derivatives as micromolar DAAO inhibitors. A pharmacophore and structure-activity relationship analysis of isatins and reported DAAO inhibitors led us to investigate 1H-indazol-3-ol derivatives and nanomolar inhibitors were identified. The series was further characterized by pKa and isothermal titration calorimetry measurements. Representative compounds exhibited beneficial properties in in vitro metabolic stability and PAMPA assays. 6-fluoro-1H-indazol-3-ol (37) significantly increased plasma d-serine level in an in vivo study on mice. These results show that the 1H indazol-3-ol series represents a novel class of DAAO inhibitors with the potential to develop drug candidates. PMID- 29472124 TI - Design, synthesis and biological assessment of N-adamantyl, substituted adamantyl and noradamantyl phthalimidines for nitrite, TNF-alpha and angiogenesis inhibitory activities. AB - A library of 15 novel and heretofore uncharacterized adamantyl and noradamantyl phthalimidines was synthesized and evaluated for neuroprotective and anti angiogenic properties. Phthalimidine treatment in LPS-challenged cells effected reductions in levels of secreted TNF-alpha and nitrite relative to basal amounts. The primary SAR suggests nitration of adamantyl phthalimidines has marginal effect on TNF-alpha activity but promotes anti-nitrite activity; thioamide congeners retain anti-nitrite activity but are less effective reducing TNF-alpha. Site-specific nitration and thioamidation provided phthalimidine 24, effecting an 88.5% drop in nitrite concurrent with only a 4% drop in TNF-alpha. Notable anti angiogenesis activity was observed for 20, 21 and 22. PMID- 29472126 TI - Development of benzoxazole deoxybenzoin oxime and acyloxylamine derivatives targeting innate immune sensors and xanthine oxidase for treatment of gout. AB - Both the inhibition of inflammatory flares and the treatment of hyperuricemia itself are included in the management of gout. Extending our efforts to development of gout therapy, two series of benzoxazole deoxybenzoin oxime derivatives as inhibitors of innate immune sensors and xanthine oxidase (XOD) were discovered in improving hyperuricemia and acute gouty arthritis. In vitro studies revealed that most compounds not only suppressed XOD activity, but blocked activations of NOD-like receptor (NLRP3) inflammasome and Toll-like receptor 4 (TLR4) signaling pathway. More importantly, (E)-1-(6 methoxybenzo[d]oxazol-2-yl)-2-(4-methoxyphenyl)ethanone oxime (5d) exhibited anti hyperuricemic and anti-acute gouty arthritis activities through regulating XOD, NLRP3 and TLR4. Compound 5d may serve as a tool compound for further design of anti-gout drugs targeting both innate immune sensors and XOD. PMID- 29472127 TI - Synthesis of S-linked NeuAc-alpha(2-6)-di-LacNAc bearing liposomes for H1N1 influenza virus inhibition assays. AB - S-NeuAc-alpha(2-6)-di-LacNAc (5) was efficiently synthesized by a [2+2] followed by a [1+4] glycosylation, and later conjugated with 1,2-dilauroyl-sn-glycero-3 phosphoethanolamine (DLPE) to form both single-layer and multi-layer homogeneous liposomes in the presence of dipalmitoyl phosphatidylcholine (DPPC) and cholesterol. These liposomes were found to be weak inhibitors in both the influenza virus entry assay and the hemagglutination inhibition assay. The single layer liposome was found to more efficiently interfere with the entry of the H1N1 influenza virus into MDCK cells than the multilayer liposome containing 5. PMID- 29472128 TI - Educating and Training the Future Adolescent Health Workforce. AB - Unprecedented attention is now focused on adolescents with growing appreciation of their disease burden and of the opportunities of investing in adolescent health. New investments are required to build the technical capacity for policy, programming, research, and clinical care across the world, especially in resource poor settings where most adolescents live. Strategies to educate and train the future workforce are needed. Competency-based education and training is the standard of education in preservice (undergraduate and postgraduate) health education and medical specialty training. Yet competency is difficult to quantify and standardize, as are the processes that underpin competency-based education and training. The primary objective of this review was to identify how quality education in adolescent health and medicine is determined. This information was used to inform the development of a conceptual framework for institutions teaching adolescent health, which can be used to assess the quality of teaching and learning and to monitor the implementation of these adolescent health competencies. Specific teaching modalities and assessment tools that have been used to teach adolescent health are described to exemplify how an educational program can be delivered and assessed. This framework is a step toward the development of a more adolescent-competent health workforce. PMID- 29472129 TI - Reduced variability of visual left ventricular ejection fraction assessment with reference images: The Japanese Association of Young Echocardiography Fellows multicenter study. AB - BACKGROUND: Visual estimation of left ventricular ejection fraction (LVEF) is widely applied to confirm quantitative EF. However, visual assessment is subjective, and variability may be influenced by observer experience. We hypothesized that a learning session might reduce the misclassification rate. METHODS: Protocol 1: Visual LVEFs for 30 cases were measured by 79 readers from 13 cardiovascular tertiary care centers. Readers were divided into 3 groups by their experience: limited (1-5 years, n=28), intermediate (6-11 years, n=26), and highly experienced (12-years, n=25). Protocol 2: All readers were randomized to assess the effect of a learning session with reference images only or feedback plus reference images. After the session, 20 new cases were shown to all readers following the same methodology. To assess the concordance and accuracy pre- and post-intervention, each visual LVEF measurement was compared to overall average values as a reference. RESULTS: Experience affected the concordance in visual EF values among the readers. Groups with intermediate and high experience showed significantly better mean difference (MD), standard deviation (SD), and coefficient of variation (CV) than those with limited experience at baseline. The learning session with reference image reduced the MD, SD, and CV in readers with limited experience. The learning session with reference images plus feedback also reduced proportional bias. Importantly, the misclassification rate for mid-range EF cases was reduced regardless of experience. CONCLUSION: This large multicenter study suggested that a simple learning session with reference images can successfully reduce the misclassification rate for LVEF assessment. PMID- 29472130 TI - Zinc in soils, water and food crops. AB - A basic knowledge of the dynamics of zinc (Zn) in soils, water and plants are important steps in achieving sustainable solutions to the problem of Zn deficiency in crops and humans. This paper aims at reviewing and discussing the relevant aspects of the role of Zn in the soil-water-plant agro biological system: from the origins of Zn in soils and water to soil Zn deficiency distribution and the factors affecting soil Zn availability to plants, therefore to elucidate the strategies potentially help combating Zn deficiency problems in soil-plant-human continuum. This necessitates identifying the main areas of Zn deficient soils and food crops and treating them with Zn amendments, mainly fertilizers in order to increase Zn uptake and Zn use efficiency to crops. In surface and groundwater, Zn enters the environment from various sources but predominately from the erosion of soil particles containing Zn. In plants is involved in several key physiological functions (membrane structure, photosynthesis, protein synthesis, and drought and disease tolerance) and is required in small but nevertheless critical contents. Several high revenue food crops such as beans, citrus, corn, rice etc are highly susceptible to Zn deficiency and biofortification is considered as a promising method to accumulate high content of Zn especially in grains. With the world population continuing to rise and the problems of producing extra food rich in Zn to provide an adequate standard of nutrition to increase, it is very important that any losses in production easily corrected so as Zn deficiencies are prevented. PMID- 29472131 TI - Species fractionation in a case-control study concerning Parkinson's disease: Cu amino acids discriminate CSF of PD from controls. AB - BACKGROUND: Parkinson's disease is affecting about 1% of the population above 65 years. Improvements in medicine support prolonged lifetime which increases the total concentration of humans affected by the disease. It is suggested that occupational and environmental exposure to metals like iron (Fe), manganese (Mn), copper (Cu) and zinc (Zn) can influence the risk for Parkinson's disease. These metals play a key role as cofactors in many enzymes and proteins. METHODS: In this case-control study, we investigated the Mn-, Fe-, Cu- and Zn-species in cerebrospinal fluid (CSF) by size-exclusion chromatography hyphenated to inductively coupled plasma mass spectrometry (SEC-ICP-MS) and the total concentration of these metals by inductively coupled plasma sector field mass spectrometry (ICP-sf-MS). RESULTS: The investigation of total metal concentration and speciation provided only minor changes, but it produced strong significance for a number of ratios. The analysis revealed a strong change in the ratio between total concentration of Fe and the amino acid-fraction of Cu. This could be observed when analyzing both the respective element concentrations of the fraction (which also depends on individual variation of the total element concentration) as well as when being expressed as percentage of total concentration (normalization) which more clearly shows changes of distribution pattern independent of individual variation of total element concentrations. CONCLUSION: Speciation analysis, therefore, is a powerful technique to investigate changes in a case-control study where ratios of different species play an important role. PMID- 29472133 TI - Vaccine safety testing using magnetic resonance imaging in suckling pigs. AB - Safety testing is one major part of the licensing procedure for veterinary vaccines and demands a large number of animals. Magnetic resonance imaging (MRI) was tested as an alternative, which may lead to a reduction in numbers of animals required for safety testing, and, correspondingly to a detailed description of the three-dimensional extent of the local tissue reaction repetitively in live pigs. In previous pig studies the following questions arose:To answer these questions the following study was performed by comparing two vaccine groups of suckling piglets (8 animals per group; A and B) with two control groups (4 animals per group; C and D). One control group was injected with a saline solution (C) and the other was only tattoo marked (D). The animals were examined using MRI at days 1, 8, 15, 22, 29, 36, and 43 post vaccination, ending with a final pathomorphologic examination. Pathomorphologic examination confirmed MRI findings. Saline solution does not result in a local tissue reaction as detected after injecting vaccines. Tattoo marking causes no local tissue reaction, neither in MRI nor in pathomorphologic examination. Therefore, MRI can be used as an alternative method for safety testing of vaccines in pigs of different age categories offering repetitive measurements of local tissue reactions. Involved cells might be examined only in a final pathomorphologic examination at the end of the trial on a reduced number of animals.

AB - OBJECTIVE: Homeostatic plasticity mechanisms regulate synaptic plasticity in the human brain. Impaired homeostatic plasticity may contribute to maladaptive synaptic plasticity and symptom persistence in chronic musculoskeletal pain. METHODS: We examined homeostatic plasticity in fifty individuals with chronic low back pain (cLBP) and twenty-five pain-free controls. A single block (7-min) of anodal transcranial direct current stimulation ('single tDCS'), or two subsequent blocks (7-min and 5-min separated by 3-min rest; 'double tDCS'), were randomised across two experimental sessions to confirm an excitatory response to tDCS applied alone, and evaluate homeostatic plasticity, respectively. Corticomotor excitability was assessed in the corticomotor representation of the first dorsal interosseous muscle by transcranial magnetic stimulation-induced motor evoked potentials (MEPs) recorded before and 0, 10, 20, and 30-min following each tDCS protocol. RESULTS: Compared with baseline, MEP amplitudes increased at all time points in both groups following the single tDCS protocol (P < 0.003). Following the double tDCS protocol, MEP amplitudes decreased in pain-free controls at all time points compared with baseline (P < 0.01), and were unchanged in the cLBP group. CONCLUSION: These data indicate impaired homeostatic plasticity in the primary motor cortex of individuals with cLBP. SIGNIFICANCE: Impaired homeostatic plasticity could explain maladaptive synaptic plasticity and symptom persistence in cLBP.

AB - In 2010 serotype O foot-and-mouth disease virus of the Mya98 lineage/SEA topotype spread into most East Asian countries. During 2010-2011 it was responsible for major outbreaks in the Republic of Korea where a monovalent O/Manisa vaccine (belonging to the ME-SA topotype) was applied to help control the outbreaks. Subsequently, all susceptible animals were vaccinated every 6 months with a vaccine containing the O/Manisa antigen. Despite vaccination, the disease re occurred in 2014 and afterwards almost annually. This study focuses on the in vivo efficacy in pigs of a high quality monovalent commercial O1/Campos vaccine against heterologous challenge with a representative 2015 isolate from the Jincheon Province of the Republic of Korea. Initially, viral characterizations and r1 determinations were performed on six viruses recovered in that region during 2014-2015, centering on their relationship with the well characterized and widely available O1/Campos vaccine strain. Genetic and antigenic analysis indicated a close similarity among 2014-2015 Korean isolates and with the previous 2010 virus, with distinct differences with the O1/Campos strain. Virus neutralisation tests using O1/Campos cattle and pig post vaccination sera and recent Korean outbreak viruses predicted acceptable cross-protection after a single vaccination, as indicated by r1 values, and in pigs, by expectancy of protection. In agreement with the in vitro estimates, in vivo challenge with a selected field isolate indicated that O1/Campos primo vaccinated pigs were protected, resulting in a PD50 value of nearly 10. The results indicated that good quality oil vaccines containing the O1/Campos strain can successfully be used against isolates belonging to the O Mya98/SEA topotype.

PMID- 29472136 TI - A field-based characterization of conductivity in areas of minimal alteration: A case example in the Cascades of northwestern United States. AB - The concentration of salts in streams is increasing world-wide making freshwater a declining resource. Developing thresholds for freshwater with low specific conductivity (SC), a measure of dissolved ions in water, may protect high quality resources that are refugia for aquatic life and that dilute downstream waters. In this case example, methods are illustrated for estimating protective levels for streams with low SC. The Cascades in the Pacific Northwest of the United States of America was selected for the case study because a geophysical model indicated that the SC of freshwater streams was likely to be very low. Also, there was an insufficient range in the SC data to accurately derive a criterion using the 2011, US Environmental Protection Agency field-based extirpation concentration distribution method. Instead, background and a regression model was used to estimate chronic and acute SC levels that could extirpate 5% of benthic invertebrate genera. Background SC was estimated at the 25th centile (33MUS/cm) of the measured data and used as the independent variable in a least squares empirical background-to-criteria (B-C) model. Because no comparison could be made with effect levels estimated from a paired SC and biological data set from the Cascades, the lower 50% prediction limit (PL) was identified as an example chronic water quality criterion (97MUS/cm). The maximum exposure threshold was estimated at the 90th centile SC of streams meeting the chronic SC level. The example acute SC level was 190MUS/cm. Because paired aquatic life and SC data are often sparse, the B-C method is useful for developing SC criteria for other systems with limited data.

AB - Past studies of the oviducts have documented oviductal steroid production during the oestrous cycle in pigs. The present study examined whether the pig oviducts are the source of steroid hormones during early pregnancy. In the ampulla and isthmus, the expression of 3beta-hydroxysteroid dehydrogenase (3betaHSD) and aromatase cytochrome P450 (CYP19) mRNA by real-time PCR, cellular localization and quantities of the studied proteins by immunofluorescence and Western blot analysis, and concentration of steroid hormones in oviductal flushings by radioimmunoassay, were studied. The expression of 3betaHSD in the ampulla and isthmus was correlated (r = 0.89) and higher on Days 2-3 and 15-16 than on Days 10-11 and 12-13. CYP19 expression was elevated in the ampulla on Days 2-3, 10-11 and 15-16 and in the isthmus on Days 2-3 vs. the other days studied. The studied proteins were localized in oviductal epithelial cells. In the ampulla, the quantity of 3betaHSD protein did not change, and was greater in the isthmus on Days 2-3 vs. Days 12-13 of pregnancy. The P450arom protein quantity increased in the ampulla on Days 2-3 vs. Days 10-11 and 15-16 and vs. Days 10-11 and 12-13 in the isthmus. The concentrations of progesterone and androstenedione in oviductal flushings were lowest on Days 12-13 and on Days 2-3 and 15-16, respectively, while oestradiol-17beta and oestrone levels did not change. Porcine oviducts are the sources of steroid hormones during early pregnancy. The expression of steroidogenic enzymes primarily increases during the embryos presence in the oviduct, i.e., on Days 2-3 of pregnancy.

AB - OBJECTIVES: The present study aims to fill the gap in the literature by conducting a comprehensive research on Indian donor's intention towards voluntary blood donation in India. The study attempts to conceptualize and validate an integrative framework incorporating voluntary function inventory (VFI) in the theory of planned behaviour (TPB) model with the purpose tomeasure the voluntary blood donation intention. MATERIAL AND METHODS: Structural equation modeling (SEM) has been used to rigorously test the hypothesized interrelationships among the underlying motives influencing voluntary blood donation intention. A self administered questionnaire was used to collect data from a sample of respondents selected conveniently from selct locations in India. Total 450 completed questionnaires were received out of 1000 distributed. RESULTS: The study develops a final conceptual framework that determines the drivers of blood donor's intention towards voluntary donation. The components of theory of planned behavior (TPB) model which include 'attitude', 'subjective norms' (SN), and 'perceived behavioral control' (PBC) along with modified volunteer functions namely 'value', 'social', 'career' and 'enhancement' were found significantly explaining the donation intention in the model. CONCLUSION: The model achieves robustness with respect to predicting Indian donor's intention towards the voluntary donation of blood. The proposed model in this study advances the theory and research on thevolunteering motives towards blood donation. The study would provide a comprehensiveunderstanding of donors' intention to the practitioners, policy makers and Non-Government Organization (NGO), helping them to frame a calibrated strategydirected towards facilitating healthy blood donation practices. PMID- 29472139 TI - Amplitude-integrated electroencephalography for seizure detection in newborn infants. AB - The amplitude-integrated electroencephalogram (aEEG) is a filtered and compressed EEG trend that can be used for long-term monitoring of brain function in patients of all ages. aEEG is increasingly used in neonatal intensive care units since several studies have shown its utility in high-risk newborn infants. Main indications for aEEG monitoring include early evaluation of brain function after perinatal asphyxia and seizure detection. The aEEG is usually recorded from one or two channels derived from parietal, central, or frontal leads. Although the aEEG is very useful for identifying high-risk infants and infants with seizures, the compressed trend has limitations with regards to detection of individual seizures. However, modern monitors also display the corresponding EEG (aEEG/EEG), which increases the probability of detecting single brief seizures. For improved evaluation of electrocortical brain activity the aEEG/EEG should be assessed together with repeated conventional EEGs or multi-channel EEG monitoring in a multi-disciplinary team. PMID- 29472140 TI - Hemolytic strains of Propionibacterium acnes do not demonstrate greater pathogenicity in periprosthetic shoulder infections. AB - BACKGROUND: Hemolysis has been suggested as a feature conferring increased pathogenicity to certain Propionibacterium acnes strains in the setting of shoulder infection. The purpose of this study was to compare the virulence of hemolytic and nonhemolytic P acnes strains in patients undergoing revision shoulder arthroplasty. METHODS: Thirty-nine patients with at least 1 positive culture growth for P acnes at the time of revision surgery were identified with P acnes isolates available for hemolysis testing. Patients were grouped into those with P acnes isolates positive (n = 20) and negative (n = 19) for hemolysis. The groups were retrospectively compared based on objective perioperative findings around the time of revision surgery and the postoperative clinical course, including the need for revision surgery. All cases were classified into categories of infection (definite infection, probable infection, and probable contaminant) based on objective perioperative criteria. RESULTS: The presence of hemolysis was not significantly associated with an increased likelihood of infection (P = .968). Hemolysis demonstrated a 75% sensitivity and 26% specificity for determining infection (definite infection and probable infection categories). The hemolytic and nonhemolytic groups showed no difference regarding preoperative serum erythrocyte sedimentation rate and/or C-reactive protein level (P = .70), number of positive cultures (P = .395), time to positive culture (P = .302), and presence of positive frozen section findings (P = .501). Postoperatively, clindamycin resistance, shoulder function, and the rate of reoperation were not significantly different between the hemolytic and nonhemolytic groups. CONCLUSION: The presence of hemolysis was not associated with increased pathogenicity in patients with P acnes-positive cultures following revision shoulder arthroplasty, when assessed by objective perioperative criteria and the postoperative clinical course. PMID- 29472141 TI - T cell deficiencies as a common risk factor for drug associated progressive multifocal leukoencephalopathy. AB - Progressive multifocal leukoencephalopathy (PML) is a disease of the central nervous system caused by neuropathogenic prototypes of ubiquitous community acquired JC virus (JCV). The disease became of particular concern following its association with certain therapies that modulate immune system function without heavy immunosuppression. Due to lack of prophylactic/treatment options and poor outcomes, which often include severe disability or death, PML is a considerable concern for development of new drugs that interfere with immune system functions. In this review of clinical and research findings, we discuss the evidence that deficiencies in CD4+ T helper cells, cytotoxic CD8+ T cells, and interferon gamma are of crucial importance for development of PML under a variety of circumstances, including those associated with use of various drugs, regardless of differences in their mechanisms of action. These deficiencies apparently enable transformation of the harmless JCV archetype into neuropathogenic prototypes, but the site(s), and the mechanisms, of this transformation are yet to be elucidated. Here we discuss the evidence for brain as one of the sites of this transformation, and propose a model of PML pathogenesis that emphasizes the central role of T cell deficiencies in the two life cycles of the JCV, one non pathogenic and one neuropathogenic. Finally, we conclude that the development of clinical grade T cell functional tests and more consistent use of already available laboratory tests for T cell subset analysis would greatly aid the effort to more accurately predict and assess the magnitude of PML risk for concerned therapeutic interventions.

AB - BACKGROUND: Laparoscopic mesh sacropexy (LS) or transvaginal mesh repair (TVM) are surgical techniques used to treat cystoceles. Health authorities have highlighted the need for comparative studies to evaluate the safety of surgeries with meshes. OBJECTIVE: To compare the rate of complications, and functional and anatomical outcomes between LS and TVM. DESIGN, SETTING, AND PARTICIPANTS: Multicenter randomized controlled trial from October 2012 to April 2014 in 11 French public hospitals. Women with cystocele stage >=2 (pelvic organ prolapse quantification), aged 45-75 yr, without previous prolapse surgery. INTERVENTION: Synthetic nonabsorbable mesh placed in the vesicovaginal space, sutured to the promontory (LS) or maintained by arms through pelvic ligaments (TVM). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Rate of surgical complications >=grade II according to the modified Clavien-Dindo classification at 1 yr. Secondary outcomes were reintervention rate, and functional and anatomical results. RESULTS AND LIMITATIONS: A total of 130 women were randomized in LS and 132 in TVM; five women withdrew before intervention, leaving 129 in LS and 128 in TVM. The rate of complications >=grade II was lower after LS than after TVM, but did not meet statistical significance (17% vs 26%, treatment difference 8.6% [95% confidence interval, CI -1.5 to 18]; p=0.088). The rate of complications of grade III or higher was nonetheless significantly lower after LS (LS=0.8%, TVM=9.4%, treatment difference 8.6% [95% CI 3.4%; 15%]; p=0.001). LS was converted to TVM in 6.3%. The total reoperation rate was lower after LS but did not meet statistical significance (LS=4.7%, TVM=10.9%, treatment difference 6.3% [95% CI -0.4 to 13.3]; p=0.060). There was no difference in symptoms, quality of life, improvement, composite definition of success, anatomical results rates between groups except for the vaginal apex and length, and dyspareunia (in favor of LS). CONCLUSIONS: LS is a valuable option for primary repair of cystocele in sexually active patients. LS is safer than TVM, but may not be feasible in all cases. Both techniques offer same functional outcomes, success rates, and anatomical outcomes, but sexual function is better preserved by LS. PATIENT SUMMARY: Our study demonstrates that laparoscopic sacropexy (LS) is a valuable option for primary repair of cystocele. LS offers equivalent success rates to vaginal mesh procedures, but is safer with a lower rate of complications and reoperations, and sexual function is better preserved.

AB - The verbal fluency task (VFT) is a well-established cognitive marker for mild cognitive impairment (MCI) in the prodromal stage of Alzheimer's dementia (AD). The behavioral VFT performance of patients allows the prediction of dementia two years later. But effective compensatory mechanism might cover or reduce the predictive value of the VFT. Therefore the aim of this study is to measure the hemodynamic response during VFT in patients with mild cognitive impairment (MCI) to establish the hemodynamic response during the VFT as a screening instrument for the prediction of dementia. One method which allows measuring the hemodynamic response during speech production without severe problems with moving artifacts like in functional magnetic resonance imaging (fMRI) is the functional near infrared spectroscopy (fNIRS). It is optimal as a screening instrument, as it is easy to apply and without any contraindications. In this study we assessed the hemodynamic response in prefrontal and temporal regions in patients with MCI as well as matched healthy controls with fNIRS. We found a decreased hemodynamic response in the inferior frontotemporal cortex for the MCI group. Our results indicate that a frontotemporal decreased hemodynamic response could serve as a diagnostic biomarker for dementia. PMID- 29472146 TI - Machine Learning Algorithms Utilizing Quantitative CT Features May Predict Eventual Onset of Bronchiolitis Obliterans Syndrome After Lung Transplantation. AB - RATIONALE AND OBJECTIVES: Long-term survival after lung transplantation (LTx) is limited by bronchiolitis obliterans syndrome (BOS), defined as a sustained decline in forced expiratory volume in the first second (FEV1) not explained by other causes. We assessed whether machine learning (ML) utilizing quantitative computed tomography (qCT) metrics can predict eventual development of BOS. MATERIALS AND METHODS: Paired inspiratory-expiratory CT scans of 71 patients who underwent LTx were analyzed retrospectively (BOS [n = 41] versus non-BOS [n = 30]), using at least two different time points. The BOS cohort experienced a reduction in FEV1 of >10% compared to baseline FEV1 post LTx. Multifactor analysis correlated declining FEV1 with qCT features linked to acute inflammation or BOS onset. Student t test and ML were applied on baseline qCT features to identify lung transplant patients at baseline that eventually developed BOS. RESULTS: The FEV1 decline in the BOS cohort correlated with an increase in the lung volume (P = .027) and in the central airway volume at functional residual capacity (P = .018), not observed in non-BOS patients, whereas the non-BOS cohort experienced a decrease in the central airway volume at total lung capacity with declining FEV1 (P = .039). Twenty-three baseline qCT parameters could significantly distinguish between non-BOS patients and eventual BOS developers (P < .05), whereas no pulmonary function testing parameters could. Using ML methods (support vector machine), we could identify BOS developers at baseline with an accuracy of 85%, using only three qCT parameters. CONCLUSIONS: ML utilizing qCT could discern distinct mechanisms driving FEV1 decline in BOS and non-BOS LTx patients and predict eventual onset of BOS. This approach may become useful to optimize management of LTx patients. PMID- 29472148 TI - The man whose head expanded. PMID- 29472147 TI - Phosphoinositide 3-kinase pathways and autophagy require phosphatidylinositol phosphate kinases. AB - Phosphatidylinositol phosphate kinases (PIPKs) generate a lipid messenger phosphatidylinositol 4,5-bisphosphate (PI4,5P2) that controls essentially all aspects of cellular functions. PI4,5P2 rapidly diffuses in the membrane of the lipid bilayer and does not greatly change in membrane or cellular content, and thus PI4,5P2 generation by PIPKs is tightly linked to its usage in subcellular compartments. Based on this verity, recent study of PI4,5P2 signal transduction has been focused on investigations of individual PIPKs and their underlying molecular regulation of cellular processes. Here, we will discuss recent advances in the study of how PIPKs control specific cellular events through assembly and regulation of PI4,5P2 effectors that mediate specific cellular processes. A focus will be on the roles of PIPKs in control of the phosphoinositide 3-kinase pathway and autophagy. PMID- 29472149 TI - The Effect of Parkinson Disease Tremor Phenotype on Cepstral Peak Prominence and Transglottal Airflow in Vowels and Speech. AB - OBJECTIVES: The physiological manifestations of Parkinson disease are heterogeneous, as evidenced by disease subtypes. Dysphonia has been well documented as an early and progressively significant impairment associated with the disease. The purpose of this study was to investigate how acoustic and aerodynamic measures of vocal function were affected by Parkinson tremor subtype (phenotype) in an effort to better understand the heterogeneity of voice impairment severity in Parkinson disease. STUDY DESIGN: This is a prospective case-control study. METHODS: Thirty-two speakers with Parkinson disease assigned to tremor and nontremor phenotypes and 10 healthy controls were recruited. Sustained vowels and connected speech were recorded from each speaker. Acoustic measures of cepstral peak prominence (CPP) and aerodynamic measures of transglottal airflow (TAF) were calculated from the recorded acoustic and aerodynamic waveforms. RESULTS: Speakers with a nontremor dominant phenotype exhibited significantly (P < 0.05) lower CPP and higher TAF in vowels compared with the tremor dominant phenotype and control speakers, who were not different from each other. No significant group differences were observed for CPP or TAF in connected speech. CONCLUSIONS: When producing vowels, participants with nontremor dominant phenotype exhibited reduced phonation periodicity and elevated TAF compared with tremor dominant and control participants. This finding is consistent with differential limb-motor and cognitive impairments between tremor and nontremor phenotypes reported in the extant literature. Results suggest that sustained vowel production may be sensitive to phonatory control as a function of Parkinson tremor phenotype in mild to moderate stages of the disease. PMID- 29472150 TI - Cost Analysis of Channeled, Distal Chip Laryngoscope for In-office Laryngopharyngeal Biopsies. AB - OBJECTIVE: Given that financial considerations play an increasingly prominent role in clinical decision-making, we sought (1) to determine the cost effectiveness of in-office biopsy for the patient, the provider, and the health care system, and (2) to determine the diagnostic accuracy of in-office biopsy. STUDY DESIGN: Retrospective, financial analyses were performed. METHODS: Patients who underwent in-office (Current Procedural Terminology Code 31576) or operative biopsy (CPT Code 31535) for laryngopharyngeal lesions were included. Two financial analyses were performed: (1) the average cost of operating room (OR) versus in-office biopsy was calculated, and (2) a break-even analysis was calculated to determine the cost-effectiveness of in-office biopsy for the provider. In addition, the diagnostic accuracy of in-office biopsies and need for additional biopsies or procedures was recorded. RESULTS: Of the 48 patients included in the current study, 28 underwent in-office biopsy. A pathologic sample was obtained in 26 of 28 (92.9%) biopsies performed in the office. Of these patients, 16 avoided subsequent OR procedures. The average per patient cost was $7000 and $11,000 for in-office and OR biopsy, respectively. Break-even analysis demonstrated that the provider could achieve a profit 2 years after purchase of the necessary equipment. CONCLUSION: In-office laryngopharyngeal biopsies are accurate and, overall, more cost-effective than OR biopsies. Purchase of the channeled, distal chip laryngoscope and biopsy forceps to perform in-office biopsies can be profitable for a provider with a videolaryngoscopy tower. In office biopsy should be considered the initial diagnostic tool for suspected laryngopharyngeal malignancies noted on videolaryngoscopy.

AB - Leachate from urban solid waste landfills is a complex mixture of organic and inorganic substances that cause damage to the environment, due to the high concentration of recalcitrant organic matter and toxicity. The objective of this study was to apply advanced oxidation processes (AOP), namely the dark Fenton and solar photo-Fenton processes, to young and old landfill leachates prior to biological treatment. The leachates were obtained from the Seropedica and Gramacho landfill sites, respectively, located in Rio de Janeiro State, Brazil. For the two Fenton processes, different conditions of pH (1.5, 3.0 and 5.0) and Fe2+: H2O2 ratio (1:2, 1:5 and 1:10) were evaluated. Biodegradability was evaluated using the Zahn-Wellens methodology and Aliivibrio fischeri acute toxicity tests were conducted in order to predict the toxicity in the activated sludge. The best conditions for both Fenton processes were pH of 3.0 and Fe2+: H2O2 and CODRAW:H2O2 mass ratios of 1:5 and 1:1, respectively. The solar photo Fenton process was more effective at improving the quality for both leachates, reaching COD, TOC and abs 254 nm reductions of 82%, 85% and 96.3%, respectively, for the Seropedica landfill leachate. In the case of the Gramacho landfill leachate, the corresponding reductions were 78.2, 80.7% and 91.1%, respectively. The biodegradability results for the untreated leachates from the Seropedica and Gramacho sites were 65% and 30% respectively. The biodegradability of both leachates was improved by the Fenton processes, especially the solar photo-Fenton process, which increased the leachate biodegradability to 89% (Seropedica) and 69% (Gramacho). For both leachates, a greater reduction in the acute toxicity was achieved with the solar photo-Fenton compared to the dark-Fenton process. The Seropedica landfill leachate showed high toxicity (EC50 = 33%, 15 min), after the dark Fenton and solar photo Fenton processes, with EC50 values of 81 and 91%, respectively. In the case of Gramacho landfill leachate toxicity, the EC50 value of the raw leachate was 13%, whereas after the dark Fenton and solar photo Fenton processes the corresponding values were 54% and 59%, respectively. These results indicate that the Fenton process (especially solar photo-Fenton), was efficient in terms of increasing the biodegradability and reducing the toxicity of the leachate. This is important in relation to protecting the microbiological community in the activated sludge process.

AB - An upsurge of end-of-life vehicles (ELVs) is emerging in China, which means a potential monumental environmental crisis. The approach of disassembly line is expected to be an effective solution to such increasing volumes. Due to the complexity of vehicle product and uncertainties of disassembly processes, a complete set of disassembly line system should be taken into detailed consideration. We have designed and constructed a novel disassembly line using a flexible transition technique with the objective of complete disassembly. Prior to productivity testing, comparative Arena-based simulations on four scenarios have been performed and finally a best scenario is selected. The results show that the guarantee of cycle time is the key to meet the productivity target of 30,000 vehicles for one year. To achieve it, some constructive measures such as forcible entry tools are given. PMID- 29472153 TI - Global status of recycling waste solar panels: A review. AB - With the enormous growth in the development and utilization of solar-energy resources, the proliferation of waste solar panels has become problematic. While current research into solar panels has focused on how to improve the efficiency of the production capacity, the dismantling and recycling of end-of-life (EOL) panels are seldom considered, as can be seen, for instance, in the lack of dedicated solar-panel recycling plants. EOL solar-panel recycling can effectively save natural resources and reduce the cost of production. To address the environmental conservation and resource recycling issues posed by the huge amount of waste solar panels regarding environmental conservation and resource recycling, the status of the management and recycling technologies for waste solar panels are systemically reviewed and discussed in this article. This review can provide a quantitative basis to support the recycling of PV panels, and suggests future directions for public policy makers. At present, from the technical aspect, the research on solar panel recovery is facing many problems, and we need to further develop an economically feasible and non-toxic technology. The research on solar photovoltaic panels' management at the end of life is just beginning in many countries, and there is a need for further improvement and expansion of producer responsibility.

PMID- 29472155 TI - The 'WiFi' otoplasty : Combined concentric posterior microchondrectomies and sutures for correction of prominent ears. AB - BACKGROUND: Prominent ears are by far the most common congenital ear deformity. Many techniques have been described using one or a combination of 3 basic methods: cartilage cutting, cartilage weakening and pure cartilage shaping techniques. The ideal otoplasty technique should yield a natural correction of the deformity, with low recurrence rates and with little risk of complications. METHODS: A new cartilage shaping technique using closing wedge concentric microchondrectomies through an entirely posterior approach is presented. Between 2006 and 2017, 200 bilateral otoplasties using this 'WiFi' pattern technique were performed. This technique combined with Mustarde sutures is based on the excision of concentric partial thickness cartilage wedges designed in the pattern of the WiFi symbol. RESULTS: There were no major complications such as anterior skin necrosis and no returns to theatre for infections or haematomas. 3 patients (1.5%) had complete recurrence of the deformity and 10 patients (5%) had to undergo a minor revision for recurrence at the upper pole. 5 patients have had exposure of the end of the permanent upper pole scapho-temporal suture more than 3 months after surgery requiring simple outpatient suture trimming/removal without any recurrence of results. Palpable or bridging sutures were present upon clinical examination in 10 patients (5%) but did not require revision surgery. CONCLUSIONS: Here, we describe a fast, safe and reliable technique for otoplasty with no need for extensive dissection, which is applicable to the full range of deformity.

AB - A sea change has occurred in the treatment options available for metastatic urothelial bladder cancer with the recent Food and Drug Administration approval of 5 immune checkpoint blockade agents for patients who have progressed on platinum-based chemotherapy or are not candidates for cisplatin. Additionally, comprehensive characterization of the landscape of genomic alterations in this disease through The Cancer Genome Atlas and other efforts has detected numerous potential targets for small molecule inhibitors. Detailed analysis of the urothelial carcinoma transcriptome has allowed for molecular subtyping of the disease and the ramifications of these subtypes upon treatment response is an active area of investigation. Coupled with these advances is a critical unmet need to define predictive biomarkers of response to therapy. Here, we highlight select research relevant to the validation and continued discovery of novel biomarkers to advance precision oncology in bladder cancer.

MRI showed a well defined intradural extramedular dumbbell-shaped lesion, associated to a left paravertebral tumor at D5-D6 level. The tumor was embolizated prior to surgery. Following she underwent a D4-D6 laminotomy, left D5-D6 costotransversectomy and resection of the intracanal extradural part of the lesion with section of the left D5 nerve. Posteriorly, complete resection of the extracanal portion of the tumor was performed by a postero-lateral approach. The anatomopathologic diagnosis was a malignant schwannoma. After the surgery, the patient required adyuvant radiotherapic treatment. Malignant schwannoma is a very uncommon tumor which belongs to the malignant peripheral nerve sheath tumors (MPNST). It develops from Schwann cells. It is frequently associated with type 1 neurofibromatosis. MPNST usually present local recurrence and can metastatize.

Primary health care is the ideal setting to support the bereaved, but we do not know much about the care plans designed by primary health care nurses in the treatment of grief. OBJECTIVE: To identify the outcomes criteria and interventions planned by nurses for mourners with and without complications in the Canary Islands. METHOD: Retrospective longitudinal study, using the electronic health records of the Canary Islands health service of people with a diagnosis of grieving, risk of complicated grieving and complicated grieving, in the period 2009-2014. RESULTS: NOC outcomes criteria were recorded in 67% of the mourners, and up to 24 different outcomes were identified. The main outcomes measures were Grief resolution; Psychosocial adjustment, Life change; Coping; Family coping; Family social climate and Caregiver emotional health. The remaining outcomes were present in less than 1% of the mourners. Although the outcomes criteria proposed by nurses in the mourners with and without complications were quite homogeneous, differences in interventions were found. In 67% of the cases, NIC interventions were reported. Ninety-nine different interventions were identified in the mourners; the most frequent were Emotional support; Grief work facilitation; Active listening; Coping enhancement and counselling. The remaining identified interventions were present in less than 5% of patients. The main interventions in the mourners with complications were Grief work facilitation; Coping enhancement; Active listening; Counselling and Family integrity promotion. CONCLUSION: Nurses state that there are more interventions and outcomes in mourners with complications. Given the few methodologically reliable studies that prove their effectiveness, continued research in this area is recommended. PMID- 29472161 TI - Overview of the management of postural tachycardia syndrome in pregnant patients. AB - Postural tachycardia syndrome (POTS) is a chronic condition characterized by symptoms of orthostatic intolerance. Pregnancy can cause different physiological changes in cardiovascular parameters, that could have greater impact on POTS patients. In this review, we discuss the management of POTS in the pregnant and obstetric settings. PMID- 29472160 TI - Babesia microti thioredoxin 3 is an effective antioxidant and involved in the response to antiprotozoal drugs. AB - The intra-erythrocytic apicomplexan Babesia microti is the predominant pathogen that causes human babesiosis, an infectious disease that occurs worldwide. B. microti relies on the antioxidant including thioredoxin system to maintain the redox balance during the erythrocytic stage. In the present study, the full length B. microti thioredoxin 3 (BmTrx3) gene was cloned, expressed in vitro, and its response to antiprotozoal drugs were tested. The full-length BmTrx3 was 663 bp and contained an intact open reading frame of 567 bp. The encoded polypeptide was 188 amino acids and the predicted molecular weight of the protein was 21.7 kDa. A conserved thioredoxin-like family domain was found in BmTrx3. The expression of BmTrx3 was upregulated on both the third and eighth day post infection in mice, whereas expression was downregulated during the beginning and later stages. Western blot analysis showed that mouse anti-BmTrx3 serum could recognize the native BmTrx3 in parasite lysates and that the mouse anti-B. microti serum could recognize the recombinant BmTrx3 protein. Immunofluorescence microscopy showed that BmTrx3 localized in the cell cytoplasm of B. microti merozoites in B. microti-infected red blood cells. The results of bovine insulin reduction assay indicated the enzyme activity of the purified recombinant BmTrx3 protein. The anti-malaria drug chloroquine significantly inhibited the expression of BmTrx3, however, another anti-malaria drug qunine, and a known anti-babesiosis drug clindamycin, induced significantly higher upregulation of BmTrx3 mRNA. The results of the present study demonstrate that BmTrx3 is a functional enzyme with antioxidant activity and may be involved in the response of B. microti to anti parasite drugs.

PMID- 29472163 TI - Validation of an algorithm-based definition of treatment resistance in patients with schizophrenia. AB - Large-scale pharmacoepidemiological research on treatment resistance relies on accurate identification of people with treatment-resistant schizophrenia (TRS) based on data that are retrievable from administrative registers. This is usually approached by operationalising clinical treatment guidelines by using prescription and hospital admission information. We examined the accuracy of an algorithm-based definition of TRS based on clozapine prescription and/or meeting algorithm-based eligibility criteria for clozapine against a gold standard definition using case notes. We additionally validated a definition entirely based on clozapine prescription. 139 schizophrenia patients aged 18-65years were followed for a mean of 5years after first presentation to psychiatric services in South-London, UK. The diagnostic accuracy of the algorithm-based measure against the gold standard was measured with sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). A total of 45 (32.4%) schizophrenia patients met the criteria for the gold standard definition of TRS; applying the algorithm-based definition to the same cohort led to 44 (31.7%) patients fulfilling criteria for TRS with sensitivity, specificity, PPV and NPV of 62.2%, 83.0%, 63.6% and 82.1%, respectively. The definition based on lifetime clozapine prescription had sensitivity, specificity, PPV and NPV of 40.0%, 94.7%, 78.3% and 76.7%, respectively. Although a perfect definition of TRS cannot be derived from available prescription and hospital registers, these results indicate that researchers can confidently use registries to identify individuals with TRS for research and clinical practices.

PMID- 29472164 TI - Associations of independent living and labor force participation with impairment indicators in schizophrenia and bipolar disorder at 20-year follow-up. AB - BACKGROUND: Since the Iowa 500 study, residential and occupational status have been frequently used as indicators of everyday achievements in research on schizophrenia and bipolar disorder. The relationships of residential and occupational status with impairment in multiple domains including physical health indicators across these two diagnoses, however, have rarely been studied. We examined these relationships at the 20-year follow-up assessment of a first admission sample. METHODS: We included 146 participants with schizophrenia and 87 with bipolar disorder with psychosis who participated in the 20-year follow-up of the Suffolk County Mental Health Project. In addition to interviewer-based ratings of employment and residential independence, we examined self-reported impairment derived from the WHODAS, standard measures of current psychopathology, indicators of obesity, as well as performance-based measures of physical and cognitive functioning. RESULTS: Participants with bipolar disorder were more likely to live independently and be gainfully employed; they also performed significantly better on each indicator of impairment apart from balance ability. In both groups, unemployment, but not residential independence, was associated with greater self-reported disability on the WHODAS. Residential independence, gainful employment, and subjective disability were also associated with better physical functioning. Across the two groups, psychiatric symptoms and physical functioning were the major determinants of subjective disability. DISCUSSION: People with psychotic bipolar disorder were more likely to be gainfully employed and living independently than participants with schizophrenia but as a group, much less frequently than population standards. Interventions aimed at physical fitness may have the potential to improve both objective functioning and perceived disability.

PMID- 29472167 TI - Preliminary evidence for neural responsiveness to infants in mothers with schizophrenia and the implications for healthy parenting. AB - Schizophrenia is a severe mental illness that may significantly affect maternal sensitive behaviour. Neural correlates of maternal behaviour represent a potentially valuable means of differentiating objectively between healthy mothers expressing variations in maternal sensitivity. As mothers with schizophrenia (MWS) show deficits in behavioural responses to infants compared to healthy mothers, we explored whether maternal brain responses to infant stimuli would be significantly reduced in MWS. We also examined whether differences in maternal behaviour between healthy and ill mothers (during play interactions with own infant) were associated with differences in brain activation to infant stimuli. We found no evidence of differential 'maternal brain' responses or 'maternal behavioural' responses in 11 new MWS compared to 20 healthy new mums; neither were neural responses to infants linked to behavioural or cognitive aspects of the mother's relationship with her infant in MWS. These preliminary findings suggest maternal sensitivity differences between MWS and healthy mothers, suggested in previous studies, may be reversible in stable treated MWS. PMID- 29472168 TI - Stability of Locking Plate and Compression Screws for Lapidus Arthrodesis: A Biomechanical Comparison of Plate Position. AB - Lapidus (first tarsometatarsal joint) arthrodesis is an established and widely used procedure for the management of moderate to severe hallux valgus, especially in cases involving hypermobility of the first tarsometatarsal joint. Multiple fixation methods are available, and several previous investigations have studied the relative strengths of these methods, including dorsomedial and plantar plating comparisons. However, these studies compared plates of varying designs and mechanical properties and used varying modes of compression and interfragmentary screw techniques. The present study mechanically investigated the resulting motion, stiffness, and strength of identical locking plate constructs fixed at various anatomic positions around the first tarsometatarsal joint. In a bench-top study, fourth-generation composite bones were divided into 3 fixation groups, each having identical interfragmentary screw applications, and randomized to 1 of 3 plate positions: dorsal, medial, or plantar. The plates applied in each case were identical locking plates, precontoured to fit the anatomy. Each construct was experimentally tested using a cantilever bending approach. The outcomes obtained were stiffness, yield force, displacement at yield, ultimate force, and displacement at ultimate force. The plantar plate position showed superior initial stiffness and force to ultimate failure. The plantar and medial plate positions exhibited superior force to yield. The medial plate position was superior regarding displacement tolerated before the yield point and catastrophic failure. The dorsal plate position was not superior for any outcome measured. Plantar and medial plating each offered biomechanical benefits. Clinical studies using similarly matched constructs are required to show whether these findings translate into improved clinical outcomes. PMID- 29472169 TI - Malignant Hidradenocarcinoma in the Lower Extremity: A Case Report of a Rare Tumor. AB - Malignant hidradenocarcinomas are rare soft tissue tumors of sweat gland origin. We present the case of a soft tissue, fungating tumor of 15 years' duration of the medial ankle in an 85-year-old male that exhibited malignant features clinically and radiographically. Subsequent punch biopsy revealed a diagnosis of malignant hidradenocarcinoma. Given the risk of recurrence and the poor radiation and chemotherapy options, the patient initially decided to leave the lesion untreated. However, he soon developed lower extremity cellulitis from the exposed lesion and decided to have the tumor excised, eliminating the source of the infection. In the present case study, we discuss the etiology, clinical and radiographic characteristics, and treatment options for this rare lesion. At the 18-month follow-up visit, he had had no recurrence of the lesion. PMID- 29472170 TI - Surgical Treatment of Neglected Bilateral Hemophilic Equinus Contracture With External Fixation: A Case Report. AB - Hemophilia is a disorder of blood coagulation with X-linked recessive inheritance. It is characterized by uncontrollable hemorrhage, and 80% of these occur intraarticularly. With recurrent hemarthrosis, recurrent synovitis occurs, which eventually leads to the formation of articular contractures. The key to the prevention of hemophilic joint complications is successful prevention of bleeding and management of the initial hemarthrosis. However, after the development of a rigid contracture, surgical correction remains the only method to correct the deformity. Achilles tendon lengthening, synovectomy, anterior osteophyte resection, corrective osteotomies, external fixators, or arthrodesis should be considered as surgical options. In the present report, we describe our experience using hybrid-type external fixators to manage bilateral neglected rigid equinus contractures in a hemophilic patient, with 78 months of follow-up data.

PMID- 29472173 TI - Co-Designing a Collaborative Chronic Care Network (C3N) for Inflammatory Bowel Disease: Development of Methods. AB - BACKGROUND: Our health care system fails to deliver necessary results, and incremental system improvements will not deliver needed change. Learning health systems (LHSs) are seen as a means to accelerate outcomes, improve care delivery, and further clinical research; yet, few such systems exist. We describe the process of codesigning, with all relevant stakeholders, an approach for creating a collaborative chronic care network (C3N), a peer-produced networked LHS. OBJECTIVE: The objective of this study was to report the methods used, with a diverse group of stakeholders, to translate the idea of a C3N to a set of actionable next steps. METHODS: The setting was ImproveCareNow, an improvement network for pediatric inflammatory bowel disease. In collaboration with patients and families, clinicians, researchers, social scientists, technologists, and designers, C3N leaders used a modified idealized design process to develop a design for a C3N. RESULTS: Over 100 people participated in the design process that resulted in (1) an overall concept design for the ImproveCareNow C3N, (2) a logic model for bringing about this system, and (3) 13 potential innovations likely to increase awareness and agency, make it easier to collect and share information, and to enhance collaboration that could be tested collectively to bring about the C3N. CONCLUSIONS: We demonstrate methods that resulted in a design that has the potential to transform the chronic care system into an LHS. PMID- 29472175 TI - Impact of a Student-Driven, Virtual Patient Application on Objective Structured Clinical Examination Performance: Observational Study. AB - BACKGROUND: Peer-assisted learning (PAL) refers to a learning activity whereby students of similar academic level teach and learn from one another. Groupe de perfectionnement des habiletes cliniques (Clinical Skills Improvement Group), a student organization at Universite Laval, Canada, propelled PAL into the digital era by creating a collaborative virtual patient platform. Medical interviews can be completed in pairs (a student-patient and a student-doctor) through an interactive Web-based application, which generates a score (weighted for key questions) and automated feedback. OBJECTIVES: The aim of the study was to measure the pedagogical impact of the application on the score at medical interview stations at the summative preclerkship Objective Structured Clinical Examination (OSCE). METHODS: We measured the use of the application (cases completed, mean score) in the 2 months preceding the OSCE. We also accessed the results of medical interview stations at the preclerkship summative OSCE. We analyzed whether using the application was associated with higher scores and/or better passing grades (>=60%) at the OSCE. Finally, we produced an online form where students could comment on their appreciation of the application. RESULTS: Of the 206 students completing the preclerkship summative OSCE, 170 (82.5%) were registered users on the application, completing a total of 3133 cases (18 by active user in average, 7 minutes by case in average). The appreciation questionnaire was answered online by 45 students who mentioned appreciating the intuitive, easy-to-use, and interactive design, the diversity of cases, and the automated feedback. Using the application was associated with reduced reported stress, improved scores (P=.04), and improved passing rates (P=.11) at the preclerkship summative OSCE. CONCLUSIONS: This study suggests that PAL can go far beyond small-group teaching, showing students' potential to create helpful pedagogical tools for their peers. PMID- 29472176 TI - Inducing Behavioral Change in Seekers of Pro-Anorexia Content Using Internet Advertisements: Randomized Controlled Trial. AB - BACKGROUND: The influence of pro-anorexia (pro-ana) websites is debated, with studies indicating both negative and positive effects, as well as significant variation in the effects of different websites for those suffering from eating disorders (EDs) and the general population. Online advertising, known to induce behavioral change both online and in the physical world, has not been used so far to modify the search behavior of people seeking pro-ana content. OBJECTIVE: The objective of this randomized controlled trial (RCT) was to examine if online advertisements (ads) can change online search behaviors of users who are looking for online pro-ana content. METHODS: Using the Bing Ads system, we conducted an RCT to randomly expose the searchers for pro-ana content to 10 different ads referring people to one of the three websites: the National Eating Disorders Association, the National Institutes of Mental Health, and MyProAna. MyProAna is a pro-ana website that was found in a previous study to be associated with less pathological online behaviors than other pro-ana websites. We followed participants exposed and unexposed to the ads to explore their past and future online searches. The ads were shown 25,554 times and clicked on 217 times. RESULTS: Exposure to the ads was associated with a decrease in searches for pro ana and self-harm content. Reductions were greatest among those referred to MyProAna (reduction of 34.0% [73/215] and 37.2% [80/215] for pro-ana and self harm, respectively) compared with users who were referred elsewhere (reduction of 15.47% [410/2650] and 3.21% [85/2650], respectively), and with users who were not shown the ads, who increased their behaviors (increase of 57.12% [6462/11,314] and 4.07% [461/11,314], respectively). In addition, those referred to MyProAna increased their search for treatment, as did control users, who did so to a lesser extent. However, users referred elsewhere decreased their searches for this content. CONCLUSIONS: We found that referring users interested in ED-related content to specific pro-ana communities might lessen their maladaptive online search behavior. This suggests that those who are preoccupied with EDs can be redirected to less pathological online searches through appropriate pathways. TRIAL REGISTRATION: ClinicalTrials.gov NCT03439553; https://clinicaltrials.gov/show/NCT03439553 (Archived by WebCite at http://www.webcitation.org/6xNYnxYlw). PMID- 29472174 TI - Peer-Based Social Media Features in Behavior Change Interventions: Systematic Review. AB - BACKGROUND: Incorporating social media features into digital behavior change interventions (DBCIs) has the potential to contribute positively to their success. However, the lack of clear design principles to describe and guide the use of these features in behavioral interventions limits cross-study comparisons of their uses and effects. OBJECTIVE: The aim of this study was to provide a systematic review of DBCIs targeting modifiable behavioral risk factors that have included social media features as part of their intervention infrastructure. A taxonomy of social media features is presented to inform the development, description, and evaluation of behavioral interventions. METHODS: Search terms were used in 8 databases to identify DBCIs that incorporated social media features and targeted tobacco smoking, diet and nutrition, physical activities, or alcohol consumption. The screening and review process was performed by 2 independent researchers. RESULTS: A total of 5264 articles were screened, and 143 articles describing a total of 134 studies were retained for full review. The majority of studies (70%) reported positive outcomes, followed by 28% finding no effects with regard to their respective objectives and hypothesis, and 2% of the studies found that their interventions had negative outcomes. Few studies reported on the association between the inclusion of social media features and intervention effect. A taxonomy of social media features used in behavioral interventions has been presented with 36 social media features organized under 7 high-level categories. The taxonomy has been used to guide the analysis of this review. CONCLUSIONS: Although social media features are commonly included in DBCIs, there is an acute lack of information with respect to their effect on outcomes and a lack of clear guidance to inform the selection process based on the features' suitability for the different behaviors. The proposed taxonomy along with the set of recommendations included in this review will support future research aimed at isolating and reporting the effects of social media features on DBCIs, cross-study comparisons, and evaluations. PMID- 29472177 TI - Implementation of the Enhanced Moderated Online Social Therapy (MOST+) Model Within a National Youth E-Mental Health Service (eheadspace): Protocol for a Single Group Pilot Study for Help-Seeking Young People. AB - BACKGROUND: There is a substantial need for youth electronic mental health (e mental health) services. In addressing this need, our team has developed a novel moderated online social therapy intervention called enhanced moderated online social therapy (MOST+). MOST+ integrates real-time, clinician-delivered Web chat counseling, interactive user-directed online therapy, expert and peer moderation, and private and secure peer-to-peer social networking. MOST+ has been designed to give young people immediate, 24-hour access to anonymous, evidence-based, and short-term mental health care. OBJECTIVE: The primary aims of this pilot study were to determine the feasibility, acceptability, and safety of the intervention. Secondary aims were to assess prepost changes in key psychosocial outcomes and collect qualitative data for future intervention refinement. METHODS: MOST+ will be embedded within eheadspace, an Australian youth e-mental health service, and will be evaluated via an uncontrolled single-group study. Approximately 250 help seeking young people (16-25 years) will be progressively recruited to the intervention from the eheadspace home page over the first 4 weeks of an 8-week intervention period. All participants will have access to evidence-based therapeutic content and integrated Web chat counseling. Additional access to moderated peer-to-peer social networking will be granted to individuals for whom it is deemed safe and appropriate, through a three-tiered screening process. Participants will be enrolled in the MOST+ intervention for 1 week, with the option to renew their enrollment across the duration of the pilot. Participants will complete a survey at enrollment to assess psychological well-being and other mental health outcomes. Additional assessment will occur following account deactivation (ie, after participant has opted not to renew their enrollment, or at trial conclusion) and will include an online survey and telephone interview assessing psychological well-being and experience of using MOST+. RESULTS: Recruitment for the study commenced in October 2017. We expect to have initial results in March 2018, with more detailed qualitative and quantitative analyses to follow. CONCLUSIONS: This is the first Australia-wide research trial to pilot an online social media platform merging real-time clinical support, expert and peer moderation, interactive online therapy, and peer-to-peer social networking. The importance of the project stems from the need to develop innovative new models for the efficient delivery of responsive evidence-based online support to help-seeking young people. If successful, this research stands to complement and enhance e-mental health services in Australia. PMID- 29472178 TI - Telegerontology as a Novel Approach to Address Health and Safety by Supporting Community-Based Rural Dementia Care Triads: Randomized Controlled Trial Protocol. AB - BACKGROUND: Telegerontology is an approach using videoconferencing to connect an interdisciplinary team in a regional specialty center to patients in rural communities, which is becoming increasingly practical for addressing current limitations in rural community-based dementia care. OBJECTIVE: Using the remotely delivered expertise of the Telegerontology dementia care team, we aim to enhance the caregiver/patient/physician triad and thereby provide the necessary support for the person with dementia to "age in place." METHODS: This is a cluster randomized feasibility trial with four rural regions in the province of Newfoundland and Labrador, Canada (2 regions randomly assigned to "intervention" and 2 to "control"). The study population includes 22 "dementia triads" that consist of a community-dwelling older Canadian with moderate to late dementia, their family caregivers, and their Primary Care Physician (PCP). Over the 6-month active study period, all participants will be provided an iPad. The intervention is intended as an adjunct to existing PCP care, consisting of weekly Skype-based videoconferencing calls with the Telegerontology physician, and other team members as needed (occupational therapist, physical therapist etc). Control participants receive usual community-based dementia care with their PCP. A baseline (pre-) assessment will be performed during a home visit with the study team. Post intervention, 6- and 12-month follow-up assessments will be collected remotely using specialized dementia monitoring applications and Skype calls. Primary outcomes include admission to long-term care, falls, emergency room visits, hospital stays, and caregiver burden. RESULTS: Results will be available in March of 2018. CONCLUSIONS: Results from this study will demonstrate a novel approach to dementia care that has the potential to impact both rural PCPs, family caregivers, and people with dementia, as well as provide evidence for the utility of Telegerontology in models of eHealth-based care. PMID- 29472179 TI - Representation of Time-Relevant Common Data Elements in the Cancer Data Standards Repository: Statistical Evaluation of an Ontological Approach. AB - BACKGROUND: Today, there is an increasing need to centralize and standardize electronic health data within clinical research as the volume of data continues to balloon. Domain-specific common data elements (CDEs) are emerging as a standard approach to clinical research data capturing and reporting. Recent efforts to standardize clinical study CDEs have been of great benefit in facilitating data integration and data sharing. The importance of the temporal dimension of clinical research studies has been well recognized; however, very few studies have focused on the formal representation of temporal constraints and temporal relationships within clinical research data in the biomedical research community. In particular, temporal information can be extremely powerful to enable high-quality cancer research. OBJECTIVE: The objective of the study was to develop and evaluate an ontological approach to represent the temporal aspects of cancer study CDEs. METHODS: We used CDEs recorded in the National Cancer Institute (NCI) Cancer Data Standards Repository (caDSR) and created a CDE parser to extract time-relevant CDEs from the caDSR. Using the Web Ontology Language (OWL)-based Time Event Ontology (TEO), we manually derived representative patterns to semantically model the temporal components of the CDEs using an observing set of randomly selected time-related CDEs (n=600) to create a set of TEO ontological representation patterns. In evaluating TEO's ability to represent the temporal components of the CDEs, this set of representation patterns was tested against two test sets of randomly selected time-related CDEs (n=425). RESULTS: It was found that 94.2% (801/850) of the CDEs in the test sets could be represented by the TEO representation patterns. CONCLUSIONS: In conclusion, TEO is a good ontological model for representing the temporal components of the CDEs recorded in caDSR. Our representative model can harness the Semantic Web reasoning and inferencing functionalities and present a means for temporal CDEs to be machine-readable, streamlining meaningful searches.

AB - OBJECTIVE: To investigate the burden of clinically significant neonatal jaundice (SNJ) in Taiwan, 2000-2010. STUDY DESIGN: The nationwide, population-based health insurance database in Taiwan was used to investigate the incidence, kernicterus rate and mortality rates of SNJ cohort born between 2000 and 2010. RESULTS: From 2000 to 2010, up to 242 546 patients admitted with neonatal jaundice (NJ) were identified. The incidence of SNJ was 5.9% in 2000 and increased to 13.7% in 2010 (P<0.001). The mortality rate significantly decreased from 0.51% in 2000 to 0.26% in 2010 (P<0.001) and the average incidence of kernicterus was 0.86 per 100 000 live births, indicating dramatically decreased rates compared with earlier rates in Taiwan. CONCLUSIONS: In spite of the increased incidence rates, the rates of mortality and kernicterus in patients with NJ significantly declined in Taiwan. The public health prevention programme, clinicians' awareness and effective management might contribute to the reduction of these acute severe sequelae. PMID- 29472194 TI - Paediatric overdiagnosis modelled by coronary abnormality trends in Kawasaki disease. AB - OBJECTIVE: Compare trends in coronary artery (CA) abnormality diagnoses to trends in adverse cardiac outcomes among American children with Kawasaki disease (KD) to assess the fit of detection of CA abnormalities to an established model of overdiagnosis. DESIGN: Multicenter retrospective cohort. SETTING: 48 US children's hospitals in the Paediatric Health Information System database. PARTICIPANTS: Children <18 years receiving care for KD between 2000 and 2014. MAIN OUTCOME MEASURES: The main outcomes were rates of CA abnormality diagnoses and adverse cardiac outcomes, measured during a child's incident KD visit and longitudinally at all subsequent visits to the same hospital, through December 2016. CA abnormalities were considered severe if long-term anticoagulation other than aspirin was prescribed. Trends were tested using mixed effects logistic regression, adjusting for patient demographics. RESULTS: Among 17 809 children treated for KD, a CA abnormality was diagnosed in 1435 children (8%), including 1117 considered non-severe and 318 severe. The rate of non-severe CA abnormality diagnoses increased from 45 per 1000 patients with KD in 2000 to 81 per 1000 patients with KD in 2014, representing an adjusted 2.3-fold increased odds (95% CI 1.8 to 3.0) of diagnosis. There was no significant change in diagnoses of severe CA abnormalities. Adverse cardiac outcomes were stable over the study period at 19 per 1000 patients with KD (P=0.24 for trend). CONCLUSIONS: The rising rate of detection of non-severe CA abnormalities accompanied by an unchanging rate of adverse cardiac outcomes among American children with KD fits an overdiagnosis pattern.

PMID- 29472195 TI - Acid suppressants for managing gastro-oesophageal reflux and gastro-oesophageal reflux disease in infants: a national survey. AB - OBJECTIVES: To evaluate the diagnosis and management of reflux and gastro oesophageal reflux disease (GORD) in infants aged <1 year presenting to general practitioners (GPs). DESIGN, SETTING AND PARTICIPANTS: A nationally representative, prospective, cross-sectional survey of GP activity in Australia, 2006-2016 (Bettering the Evaluation And Care of Health Study). Annually, a random sample of around 1000 GPs recorded details for 100 consecutive visits with consenting, unidentified patients. OUTCOME MEASURES: Diagnoses of reflux and GORD and their management including prescribing of acid-suppressant medicines (proton pump inhibitors (PPIs) and histamine receptor antagonists (H2RAs)) and counselling, advice or education. RESULTS: Of all infants' visits, 512 (2.7%) included a diagnosis of reflux (n=413, 2.2%) or GORD (n=99, 0.5%). From 2006 to 2016, diagnostic rates decreased for reflux and increased for GORD. Prescribing of acid suppressants occurred in 43.6% visits for reflux and 48.5% visits for GORD, similar to rates of counselling, advice or education (reflux: 38.5%, GORD: 43.4% of visits). Prescribing of PPIs increased (statistically significant only for visits for reflux), while prescribing of H2RAs decreased. CONCLUSIONS: Overprescribing of acid suppressants to infants may be occurring. In infants, acid-suppressant medicines are no better than placebo and may have significant negative side effects; however, guidelines are inconsistent. Clear, concise and consistent guidance is needed. GPs and parents need to understand what is normal and limitations of medical therapy. We need a greater understanding of the influences on GP prescribing practices, of parents' knowledge and attitudes and of the pressures on parents of infants with these conditions. PMID- 29472197 TI - Multiple paranasal mucoceles in a child. PMID- 29472198 TI - Kangaroo mother care for the prevention of neonatal hypothermia: a randomised controlled trial in term neonates. AB - OBJECTIVE: To test the hypothesis that kangaroo mother care (KMC) initiated either at birth or at 1 hour after birth reduces moderate or severe hypothermia in term neonates at (A) 1 hour after birth and (B) at discharge when compared with standard thermoregulation care. METHODS: Term neonates born at a tertiary delivery centre in Zambia were randomised in two phases (phase 1: birth to 1 hour, phase 2: 1 hour to discharge) to either as much KMC as possible in combination with standard thermoregulation care (KMC group) or to standard thermoregulation care (control group). The primary outcomes were moderate or severe hypothermia (axillary temperature <36.0 degrees C) at (A) 1 hour after birth and (B) at discharge. RESULTS: The proportion of neonates with moderate or severe hypothermia did not differ between the KMC and control groups at 1 hour after birth (25% vs 27%, relative risk (RR)=0.93, 95% CI 0.59 to 1.4, P=0.78) or at discharge (7% vs 2%, RR=2.8, 95% CI 0.6 to 13.9, P=0.16). Hypothermia was not found among the infants who had KMC for at least 9 hours or 80% of the hospital stay. CONCLUSIONS: KMC practised as much as possible in combination with standard thermoregulation care initiated either at birth or at 1 hour after birth did not reduce moderate or severe hypothermia in term infants compared with standard thermoregulation care. The current study also shows that duration of KMC either for at least 80% of the time or at least 9 hours during the day of birth was effective in preventing hypothermia in term infants.

AB - OBJECTIVE: The objective of this study was to measure the role of platelets and red blood cells on thrombus propagation in an in vitro model of venous valvular stasis. APPROACH AND RESULTS: A microfluidic model with dimensional similarity to human venous valves consists of a sinus distal to a sudden expansion, where for sufficiently high Reynolds numbers, 2 countercurrent vortices arise because of flow separation. The primary vortex is defined by the points of flow separation and reattachment. A secondary vortex forms in the deepest recess of the valve pocket characterized by low shear rates. An initial fibrin gel formed within the secondary vortex of a tissue factor-coated valve sinus. Platelets accumulated at the interface of the fibrin gel and the primary vortex. Red blood cells at physiological hematocrits were necessary to provide an adequate flux of platelets to support thrombus growth out of the valve sinus. A subpopulation of platelets that adhered to fibrin expose phosphatidylserine. Platelet-dependent thrombus growth was attenuated by inhibition of glycoprotein VI with a blocking Fab fragment or D-dimer. CONCLUSIONS: A 3-step process regulated by hemodynamics was necessary for robust thrombus propagation: First, immobilized tissue factor initiates coagulation and fibrin deposition within a low flow niche defined by a secondary vortex in the pocket of a model venous valve. Second, a primary vortex delivers platelets to the fibrin interface in a red blood cell-dependent manner. Third, platelets adhere to fibrin, activate through glycoprotein VI, express phosphatidylserine, and subsequently promote thrombus growth beyond the valve sinus and into the bulk flow. PMID- 29472231 TI - Carotid Artery Remodeling Is Segment Specific: An In Vivo Study by Vessel Wall Magnetic Resonance Imaging. AB - OBJECTIVE: Early atherosclerosis is often undetected due in part to compensatory enlargement of the outer wall, termed positive remodeling. Variations in hemodynamic conditions and clinical factors influence the patterns of remodeling. The carotid artery provides an opportunity to examine these variations because of the unique geometry of the carotid bulb. This study aimed to determine differences in remodeling of the common, internal, and bifurcation segments of the carotid using magnetic resonance imaging. APPROACH AND RESULTS: Carotid arteries of 525 subjects without history of cardiovascular disease were imaged by magnetic resonance imaging. The carotid artery was divided into 3 segments: common carotid artery; bifurcation; and internal carotid artery. Remodeling patterns were characterized using linear regression analysis of lumen and total vessel areas (dependent variables) compared with maximum wall thickness (independent variable) for each segment, adjusted for age, sex, and height. The common carotid artery demonstrated a pattern consistent with positive remodeling, whereas the bifurcation demonstrated negative remodeling. The internal carotid artery demonstrated a mixed pattern of outer wall expansion and lumen constriction. Females and subjects with diabetes mellitus showed more positive remodeling, hypertension was associated with attenuated positive remodeling, and those with hypercholesterolemia showed more negative remodeling. CONCLUSIONS: In this cohort of 55- to 80-year-old individuals without history of cardiovascular disease, the pattern of early carotid artery remodeling was segment specific and appeared to be associated with sex and clinical characteristics. These findings provide the groundwork for longitudinal studies to define local and systemic factors such as hemodynamic and clinical conditions on carotid artery remodeling. PMID- 29472234 TI - Hypoxia Triggers SENP1 (Sentrin-Specific Protease 1) Modulation of KLF15 (Kruppel Like Factor 15) and Transcriptional Regulation of Arg2 (Arginase 2) in Pulmonary Endothelium. AB - OBJECTIVE: KLF15 (Kruppel-like factor 15) has recently been shown to suppress activation of proinflammatory processes that contribute to atherogenesis in vascular smooth muscle, however, the role of KLF15 in vascular endothelial function is unknown. Arginase mediates inflammatory vasculopathy and vascular injury in pulmonary hypertension. Here, we tested the hypothesis that KLF15 is a critical regulator of hypoxia-induced Arg2 (arginase 2) transcription in human pulmonary microvascular endothelial cells (HPMEC). APPROACH AND RESULTS: Quiescent HPMEC express ample amounts of full-length KLF15. HPMECs exposed to 24 hours of hypoxia exhibited a marked decrease in KLF15 protein levels and a reciprocal increase in Arg2 protein and mRNA. Chromatin immunoprecipitation indicated direct binding of KLF15 to the Arg2 promoter, which was relieved with HPMEC exposure to hypoxia. Furthermore, overexpression of KLF15 in HPMEC reversed hypoxia-induced augmentation of Arg2 abundance and arginase activity and rescued nitric oxide (NO) production. Ectopic KLF15 also reversed hypoxia-induced endothelium-mediated vasodilatation in isolated rat pulmonary artery rings. Mechanisms by which hypoxia regulates KLF15 abundance, stability, and compartmentalization to the nucleus in HPMEC were then investigated. Hypoxia triggered deSUMOylation of KLF15 by SENP1 (sentrin-specific protease 1), and translocation of KLF15 from nucleus to cytoplasm. CONCLUSIONS: KLF15 is a critical regulator of pulmonary endothelial homeostasis via repression of endothelial Arg2 expression. KLF15 abundance and nuclear compartmentalization are regulated by SUMOylation/deSUMOylation-a hypoxia-sensitive process that is controlled by SENP1. Strategies including overexpression of KLF15 or inhibition of SENP1 may represent novel therapeutic targets for pulmonary hypertension. PMID- 29472233 TI - Novel Role of IL (Interleukin)-1beta in Neutrophil Extracellular Trap Formation and Abdominal Aortic Aneurysms. AB - OBJECTIVE: Neutrophils promote experimental abdominal aortic aneurysm (AAA) formation via a mechanism that is independent from MMPs (matrix metalloproteinases). Recently, we reported a dominant role of IL (interleukin) 1beta in the formation of murine experimental AAAs. Here, the hypothesis that IL 1beta-induced neutrophil extracellular trap formation (NETosis) promotes AAA was tested. APPROACH AND RESULTS: NETs were identified through colocalized staining of neutrophil, Cit-H3 (citrullinated histone H3), and DNA, using immunohistochemistry. NETs were detected in human AAAs and were colocalized with IL-1beta. In vitro, IL-1RA attenuated IL-1beta-induced NETosis in human neutrophils. Mechanistically, IL-1beta treatment of isolated neutrophils induced nuclear localization of ceramide synthase 6 and synthesis of C16-ceramide, which was inhibited by IL-1RA or fumonisin B1, an inhibitor of ceramide synthesis. Furthermore, IL-1RA or fumonisin B1 attenuated IL1-beta-induced NETosis. In an experimental model of murine AAA, NETs were detected at a very early stage-day 3 of aneurysm induction. IL-1beta-knockout mice demonstrated significantly lower infiltration of neutrophils to aorta and were protected from AAA. Adoptive transfer of wild-type neutrophils promoted AAA formation in IL-1beta-knockout mice. Moreover, treatment of wild-type mice with Cl-amidine, an inhibitor NETosis, significantly attenuated AAA formation, whereas, treatment with deoxyribonuclease, a DNA digesting enzyme, had no effect on AAA formation. CONCLUSIONS: Altogether, the results suggest a dominant role of IL-1beta-induced NETosis in AAA formation. PMID- 29472235 TI - Aid agencies call for access to besieged Eastern Ghouta. PMID- 29472232 TI - Genome-Wide Association and Functional Studies Identify SCML4 and THSD7A as Novel Susceptibility Genes for Coronary Artery Disease. AB - OBJECTIVE: The genetic contribution to coronary artery disease (CAD) remains largely unclear. We combined genetic screening with functional characterizations to identify novel loci and candidate genes for CAD. APPROACH AND RESULTS: We performed genome-wide screening followed by multicenter validation in 8 cohorts consisting of 21 828 participants of Han ethnicity and identified 3 novel intragenic SNPs (single nucleotide polymorphisms), rs9486729 (SCML4 [Scm polycomb group protein-like 4]; odds ratio, 1.25; 95% CI, 1.17-1.34; P=3.51*10-11), rs17165136 (THSD7A [thrombospondin type 1 domain-containing 7A]; odds ratio 1.28; 95% CI, 1.21-1.35; P<1.00*10-25), and rs852787 (DAB1 [disabled-1]; odds ratio, 1.29; 95% CI, 1.21-1.38; P=2.02*10-14), associated with CAD with genome-wide significance. The risk allele of rs9486729 and protective allele of rs17165136 were associated with the decreased expression of their host genes, SCML4 and THSD7A, respectively, whereas rs852787 did not have transcriptional effects on any gene. Knockdown of SCML4 activated endothelial cells by increasing the expression of IL-6, E-selectin, and ICAM and weakened their antiapoptotic activity, whereas the knockdown of THSD7A had little effect on these endothelial cell functions but attenuated monocyte adhesion via decreasing the expression of ICAM, L-selectin, and ITGB2. We further showed that inhibiting the expression of SCML4 exacerbated endothelial dysfunction and vascular remodeling in a rat model with partial carotid ligation. CONCLUSIONS: We identify 3 novel loci associated with CAD and show that 2 genes, SCML4 and THSD7A, make functional contributions to atherosclerosis. How rs852787 and its host gene DAB1 are linked to CAD needs further studies. PMID- 29472236 TI - Assessment of choroidal blood flow using laser speckle flowgraphy. AB - BACKGROUND/AIMS: There is considerable interest in novel techniques to quantify choroidal blood flow (CBF) in humans. In the present study, we investigated a novel technique to measure CBF based on laser speckle flowgraphy (LSFG) in healthy subjects. METHODS: This study included 31 eyes of 31 healthy, non-smoking subjects aged between 19 and 74 years. A commercial LSFG instrument was used to measure choroidal vessel diameter (CVD) and relative flow volume (RFV) in choroidal vessels that were identified on fundus photos, an approach that was used previously only for retinal vessels. The reproducibility and the effect of isometric exercise on these parameters were investigated. The latter was compared with measurement of subfoveal CBF using laser Doppler flowmetry (LDF). RESULTS: Intraclass correlation coefficients for CVD and RFV were higher than 0.8 indicating excellent reproducibility. During isometric exercise, we observed an increase in ocular perfusion pressure of approximately 60% (P<0.001). The increase in RFV and CBF was lower, but also highly significant versus baseline (at minute 6 of isometric exercise: RFV 10.5%+/-4.2%, CBF 8.3%+/-3.6%; P<0.001 each) indicating choroidal autoregulation. CONCLUSION: LSFG may be a novel approach to study blood flow in choroidal vessels. Data are reproducible and show good agreement with LDF data. TRIAL REGISTRATION NUMBER: NCT02102880, Results.

PMID- 29472241 TI - Adrenal activity and metabolic risk during randomized escitalopram or placebo treatment in PCOS. AB - BACKGROUND/AIMS: Polycystic ovary syndrome (PCOS) is associated with insulin resistance, adrenal hyperactivity and decreased mental health. We aimed to investigate the changes in adrenal activity, metabolic status and mental health in PCOS during treatment with escitalopram or placebo. METHODS: Forty-two overweight premenopausal women with PCOS and no clinical depression were randomized to 12-week SSRI (20 mg escitalopram/day, n = 21) or placebo (n = 21). Patients underwent clinical examination, fasting blood samples, adrenocorticotroph hormone (ACTH) test, 3-h oral glucose tolerance test (OGTT) and filled in questionnaires regarding mental health and health-related quality of life (HRQoL): WHO Well-Being Index (WHO-5), Major Depression Inventory (MDI), Short Form 36 (SF-36) and PCOS questionnaire. RESULTS: Included women were aged 31 (6) years (mean (s.d.)) and had body mass index (BMI) 35.8 (6.5) kg/m2 and waist 102 (12) cm. Escitalopram was associated with increased waist (median (quartiles) change 1 (0; 3) cm), P = 0.005 vs change during placebo and increased cortisol levels (cortisol 0, cortisol 60, peak cortisol and area under the curve for cortisol during ACTH test), all P < 0.05 vs changes during placebo. Escitalopram had no significant effect on measures of insulin sensitivity, insulin secretion, fasting lipids, mental health or HRQoL. CONCLUSION: Waist circumference and cortisol levels increased during treatment with escitalopram in women with PCOS and no clinical depression, whereas metabolic risk markers, mental health and HRQol were unchanged. PMID- 29472243 TI - If the papers don't come to the journal.... PMID- 29472244 TI - Age and Other Factors Affecting the Outcome of AABR Screening in Neonates. AB - BACKGROUND: Although the utility of universal newborn hearing screening is undisputed, testing protocols vary. In particular, the impact of the infant's age at the time of automated auditory brainstem response (AABR) screening has not been well studied. METHODS: We conducted a retrospective review of newborn hearing screening data in 6817 low-risk, term and late-preterm newborns at our large, urban, academic medical center for a 1-year period to analyze the impact of age and other factors on the screening failure rate and referral for diagnostic testing. RESULTS: AABR screening failure rates decreased with postnatal age over the first 48 hours; 13.3% failed at <24 hours versus 3.8% at >=48 hours (P < .0001). Infants who were initially tested at >=36 hours failed repeat testing more often than those who were tested at <36 hours (11.5% vs 18.9%; P = .03). Other factors that were associated with failure included being a boy and of a race other than white. Sensorineural hearing loss (SNHL) was diagnosed in 18.6% of infants who failed their final screening at >=48 hours compared with 2.8% of those whose final screening occurred earlier (P = .03). SNHL was more likely in infants who failed their first screening bilaterally (21.2%) than unilaterally (4.4%); P = .03). CONCLUSIONS: Among healthy newborns, delaying AABR screening in the first 48 hours minimized failure rates. SNHL was 6 times as likely in infants who failed their final screening at >=48 hours compared with those who were screened at <48 hours of age. In our study, we offer guidance for nursery directors and audiologists who determine hearing screening protocols and counsel families about results. PMID- 29472246 TI - Counteracting the effects of TNF receptor-1 has therapeutic potential in Alzheimer's disease. AB - Alzheimer's disease (AD) is the most common form of dementia, and neuroinflammation is an important hallmark of the pathogenesis. Tumor necrosis factor (TNF) might be detrimental in AD, though the results coming from clinical trials on anti-TNF inhibitors are inconclusive. TNFR1, one of the TNF signaling receptors, contributes to the pathogenesis of AD by mediating neuronal cell death. The blood-cerebrospinal fluid (CSF) barrier consists of a monolayer of choroid plexus epithelial (CPE) cells, and AD is associated with changes in CPE cell morphology. Here, we report that TNF is the main inflammatory upstream mediator in choroid plexus tissue in AD patients. This was confirmed in two murine AD models: transgenic APP/PS1 mice and intracerebroventricular (icv) AbetaO injection. TNFR1 contributes to the morphological damage of CPE cells in AD, and TNFR1 abrogation reduces brain inflammation and prevents blood-CSF barrier impairment. In APP/PS1 transgenic mice, TNFR1 deficiency ameliorated amyloidosis. Ultimately, genetic and pharmacological blockage of TNFR1 rescued from the induced cognitive impairments. Our data indicate that TNFR1 is a promising therapeutic target for AD treatment. PMID- 29472248 TI - Introducing preLights: preprint highlights, selected by the biological community. PMID- 29472247 TI - Time-varying effects of prognostic factors associated with long-term survival in breast cancer. AB - The impact of some prognostic factors on breast cancer survival has been shown to vary with time since diagnosis. However, this phenomenon has not been evaluated in Asians. In the present study, 4886 patients were recruited from the Shanghai Breast Cancer Survival Study, a longitudinal study of patients diagnosed during 2002-2006, with a median follow-up time of 11.2 years. Cox model incorporating time-by-covariate interactions was used to describe the time-varying effects of prognostic factors related to overall survival and disease-free survival. Age >=65 years showed a progressively negative effect on breast cancer prognosis over time, whereas tumour size >2 cm had a lasting and constant impact. Age significantly modified the effects of the tumour grade, nodal status and oestrogen receptor (ER) status on breast cancer survival. The detrimental effect of poorly differentiated tumours was time limited and more obvious in patients aged 45-54 years. Having >=4 positive lymph nodes had a persistent and negative impact on prognosis, although it attenuated in later years; the phenomenon was more prominent in the 55-64-year age group. ER-positive status was protective in the first 3 years after diagnosis but was related to a higher risk of recurrence in later years; the time-point when ER-positive status turned into a risk factor was earlier in younger patients. These results suggest that older age, positive lymph node status, larger tumour size and ER-positive status are responsible for late death or recurrence in Asian breast cancer survivors. Extended endocrine therapy should be given earlier in younger ER-positive patients. PMID- 29472245 TI - Mitotic and Meiotic Functions for the SUMOylation Pathway in the Caenorhabditis elegans Germline. AB - Meiosis is a highly regulated process, partly due to the need to break and then repair DNA as part of the meiotic program. Post-translational modifications are widely used during meiotic events to regulate steps such as protein complex formation, checkpoint activation, and protein attenuation. In this paper, we investigate how proteins that are obligatory components of the SUMO (small ubiquitin-like modifier) pathway, one such post-translational modification, affect the Caenorhabditis elegans germline. We show that UBC-9, the E2 conjugation enzyme, and the C. elegans homolog of SUMO, SMO-1, localize to germline nuclei throughout prophase I. Mutant analysis of smo-1 and ubc-9 revealed increased recombination intermediates throughout the germline, originating during the mitotic divisions. SUMOylation mutants also showed late meiotic defects including defects in the restructuring of oocyte bivalents and endomitotic oocytes. Increased rates of noninterfering crossovers were observed in ubc-9 heterozygotes, even though interfering crossovers were unaffected. We have also identified a physical interaction between UBC-9 and DNA repair protein MRE-11 ubc-9 and mre-11 null mutants exhibited similar phenotypes at germline mitotic nuclei and were synthetically sick. These phenotypes and genetic interactions were specific to MRE-11 null mutants as opposed to RAD-50 or resection-defective MRE-11 We propose that the SUMOylation pathway acts redundantly with MRE-11, and in this process MRE-11 likely plays a structural role. PMID- 29472249 TI - Improved Murine MHC-Deficient HLA Transgenic NOD Mouse Models for Type 1 Diabetes Therapy Development. AB - Improved mouse models for type 1 diabetes (T1D) therapy development are needed. T1D susceptibility is restored to normally resistant NOD.beta2m-/- mice transgenically expressing human disease-associated HLA-A*02:01 or HLA-B*39:06 class I molecules in place of their murine counterparts. T1D is dependent on pathogenic CD8+ T-cell responses mediated by these human class I variants. NOD.beta2m-/--A2.1 mice were previously used to identify beta-cell autoantigens presented by this human class I variant to pathogenic CD8+ T cells and for testing therapies to attenuate such effectors. However, NOD.beta2m-/- mice also lack nonclassical MHC I family members, including FcRn, required for antigen presentation, and maintenance of serum IgG and albumin, precluding therapies dependent on these molecules. Hence, we used CRISPR/Cas9 to directly ablate the NOD H2-Kd and H2-Db classical class I variants either individually or in tandem (cMHCI-/-). Ablation of the H2-Ag7 class II variant in the latter stock created NOD mice totally lacking in classical murine MHC expression (cMHCI/II-/-). NOD cMHCI-/- mice retained nonclassical MHC I molecule expression and FcRn activity. Transgenic expression of HLA-A2 or -B39 restored pathogenic CD8+ T-cell development and T1D susceptibility to NOD-cMHCI-/- mice. These next-generation HLA-humanized NOD models may provide improved platforms for T1D therapy development. PMID- 29472250 TI - Tau protein liquid-liquid phase separation can initiate tau aggregation. AB - The transition between soluble intrinsically disordered tau protein and aggregated tau in neurofibrillary tangles in Alzheimer's disease is unknown. Here, we propose that soluble tau species can undergo liquid-liquid phase separation (LLPS) under cellular conditions and that phase-separated tau droplets can serve as an intermediate toward tau aggregate formation. We demonstrate that phosphorylated or mutant aggregation prone recombinant tau undergoes LLPS, as does high molecular weight soluble phospho-tau isolated from human Alzheimer brain. Droplet-like tau can also be observed in neurons and other cells. We found that tau droplets become gel-like in minutes, and over days start to spontaneously form thioflavin-S-positive tau aggregates that are competent of seeding cellular tau aggregation. Since analogous LLPS observations have been made for FUS, hnRNPA1, and TDP43, which aggregate in the context of amyotrophic lateral sclerosis, we suggest that LLPS represents a biophysical process with a role in multiple different neurodegenerative diseases. PMID- 29472251 TI - Secondary stroke prevention services in Canada: a cross-sectional survey and geospatial analysis of resources, capacity and geographic access. AB - BACKGROUND: Rapid assessment and management of transient ischemic attacks and nondisabling strokes by specialized stroke prevention services reduces the risk of recurrent stroke and improves outcomes. In Canada, with its vast geography and with 16.8% of the population living in rural areas, access to these services is challenging, and considerable variation in access to care exists. The purpose of this multiphase study was to identify sites across Canada providing stroke prevention services, evaluate resource capacity and determine geographic access for Canadians. METHODS: We developed a Stroke Prevention Services Resource Inventory that contained 22 questions on the organization and delivery of stroke prevention services and quality monitoring. The inventory ran from November 2015 to January 2016 and was administered online. We conducted a geospatial analysis to estimate access by drive times. Considerations were made for hours of operation and access within and across provincial borders. RESULTS: A total of 123 stroke prevention sites were identified, of which 119 (96.7%) completed the inventory. Most (95) are designated stroke prevention or rapid assessment clinics. Of the 119 sites, 68 operate full time, and 39 operate less than 2.5 days per week. A total of 87.3% of the Canadian population has access to a stroke prevention service within a 1-hour drive; however, only 69.2% has access to a service that operates 5-7 days a week. Allowing provincial border crossing improves access (< 6-h drive) for those who are beyond a 6-hour drive within their home province (3.4%). INTERPRETATION: Most Canadians have reasonable geographic access to stroke prevention services. Allowing patients to cross borders improves the existing access for many, particularly some remote communities along the Ontario-Quebec and British Columbia-Alberta borders. PMID- 29472252 TI - N_LyST: a simple and rapid screening test for Lynch syndrome. AB - AIMS: We sought to use PCR followed by high-resolution melting analysis to develop a single closed-tube screening panel to screen for Lynch syndrome. This comprises tests for microsatellite instability (MSI), MLH1 methylation promoter and BRAF mutation. METHODS: For MSI testing, five mononucleotide markers (BAT25, BAT26, BCAT25, MYB, EWSR1) were developed. In addition, primers were designed to interrogate Region C of the MLH1 promoter for methylation (using bisulphite modified DNA) and to test for mutations in codon 600 of BRAF. Two separate cohorts from Nottingham (n=99, 46 with MSI, 53 being microsatellite stable (MSS)) and Edinburgh (n=88, 45 MSI, 43 MSS) were tested. RESULTS: All the cases (n=187) were blind tested for MSI and all were correctly characterised by our panel. The MLH1 promoter and BRAF were tested only in the Nottingham cohort. Successful blinded analysis was performed on the MLH1 promoter in 97 cases. All MSS cases showed a pattern of non-methylation while 41/44 cases with MSI showed full methylation. The three cases with MSI and a non-methylated pattern had aberrations in MSH2 and MSH6 expression. BRAF mutation was detected in 61% of MSI cases and 11% of MSS cases.Finally, 12 cases were blind screened by using the whole panel as a single test. Of these, five were identified as MSS, four as MSI/non-LS and three as MSI/possible LS. These results were concordant with the previous data. CONCLUSION: We describe the Nottingham Lynch Syndrome Test (N_LyST). This is a quick, simple and cheap method for screening for Lynch syndrome. PMID- 29472253 TI - Is smoking a risk factor for tinnitus? A systematic review, meta-analysis and estimation of the population attributable risk in Germany. AB - OBJECTIVE: To assess the epidemiological association of smoking status and tinnitus with a systematic review and meta-analysis and to estimate the population attributable risk in Germany. DATA SOURCES: A systematic literature search in PubMed and ISI-Web of Science Core Collection resulted in 1026 articles that were indexed until 15 September 2015. Additionally, proceedings of the international tinnitus seminars and reference lists of relevant articles were screened. STUDY SELECTION: Two reviewers searched independently for epidemiological studies. Tinnitus as a manifestation of tumours, vascular malformations, specific syndromes or as a consequence of surgical and medical treatment was not considered. Moreover, studies conducted among patients of ear, nose and throat clinics were excluded. DATA EXTRACTION: If only raw data were provided, effect sizes were calculated. Further unpublished data were received by corresponding authors. DATA SYNTHESIS: Data of 20 studies were pooled. Current smoking (OR 1.21, 95% CI 1.09 to 1.35), former smoking (OR 1.13, 95% CI 1.01 to 1.26) and ever smoking (OR 1.20, 95% CI 1.11 to 1.30) were significantly associated with tinnitus. Moreover, sensitivity analyses for severe tinnitus (OR 1.32, 95% CI 1.10 to 1.58) and for studies of superior quality (OR 1.15, 95% CI 1.03 to 1.29) showed increased risks. According to this, the population attributable risk estimate in Germany is 3.5%. CONCLUSION: There is sufficient evidence that smoking is associated with tinnitus. As the review mainly consists of cross-sectional studies, the observed correlation does not give evidence of a causal relationship. Due to the impact of various confounders, further research is needed to provide more evidence on the strength of association and causal relationships. PMID- 29472254 TI - Comparison of new-generation drug-eluting stents versus drug-coated balloon for in-stent restenosis: a meta-analysis of randomised controlled trials. AB - OBJECTIVE: The study sought to compare angiographic and clinical outcomes of new generation drug-eluting stents (DES) versus drug-coated balloon (DCB) in patients with coronary in-stent restenosis (ISR). DESIGN: Meta-analysis using data from randomised trial found by searches on PubMed, the Cochrane Library, ClinicalTrials.gov and websites of major cardiovascular congresses. SETTING: Only randomised trials comparing DES with DCB were included. PARTICIPANTS: Patients with ISR in the included trials. INTERVENTIONS: New-generation DES versus DCB. OUTCOMES: The angiographic and clinical outcomes including cardiac death, all cause death, myocardial infarction, target lesion revascularisation (TLR), target vessel revascularisation (TVR), major adverse cardiac events (MACE) and stent thrombosis were investigated. RESULTS: Five trials including 913 patients were eligible and included. Pooled analysis in angiographic results identified that new-generation DES were associated with higher acute luminal gain (-0.31 mm, 95% CI -0.42 to -0.20, P<0.001) and lower per cent diameter stenosis (risk ratio (RR): 0.28, 95% CI 0.02 to 0.55, P=0.04). DES significantly reduced the risk of TLR (RR: 1.96, 95% CI 1.17 to 3.28, P=0.01) compared with DCB; however, there was no statistical differences for MACE (RR: 1.21, 95% CI 0.67 to 2.17, P=0.53), myocardial infarction (RR: 1.16, 95% CI 0.55 to 2.48, P=0.69) and cardiac death (RR: 1.80, 95% CI 0.60 to 5.39, P=0.29). CONCLUSIONS: Interventions with new generation DES appear to be associated with significant reduction in per cent diameter stenosis and TLR at short-term follow-up, but had similar MACE, myocardial infarction and cardiac death for patients with coronary ISR compared with DCB. Appropriately powered studies with longer term follow-up are warranted to confirm these findings. PMID- 29472255 TI - Comparison of a newly established emotional stimulus approach to a classical assessment-driven approach in BLS training: a randomised controlled trial. AB - OBJECTIVE: The study objective was to implement two strategies (short emotional stimulus vs announced practical assessment) in the teaching of resuscitation skills in order to evaluate whether one led to superior outcomes. SETTING: This study is an educational intervention provided in one German academic university hospital. PARTICIPANTS: First-yearmedical students (n=271) during the first3 weeks of their studies. INTERVENTIONS: Participants were randomly assigned to one of two groups following a sequence of random numbers: the emotional stimulus group (EG) and the assessment group (AG). In the EG, the intervention included watching an emotionally stimulating video prior to the Basic Life Support (BLS) course. In the AG, a practical assessment of the BLS algorithm was announced and tested within a 2 min simulated cardiac arrest scenario. After the baseline testing, a standardised BLS course was provided. Evaluation points were defined 1 week and 6 months after. PRIMARY OUTCOME MEASURES: Compression depth (CD) and compression rate (CR) were recorded as the primary endpoints for BLS quality. RESULTS: Within the study, 137 participants were allocated to the EG and 134 to the AG. 104 participants from EG and 120 from AG were analysed1 week after the intervention, where they reached comparable chest-compression performance without significant differences (CR P=0.49; CD P=0.28). The chest-compression performance improved significantly for the EG (P<0.01) and the AG (P<0.01) while adhering to the current resuscitation guidelines criteria for CD and CR. CONCLUSIONS: There was no statistical difference between both groups' practical chest-compression performance. Nevertheless, the 2 min video sequence used in the EG with its low production effort and costs, compared with the expensive assessment approach, provides broad opportunities for applicability in BLS training. PMID- 29472256 TI - Protocol for a longitudinal twin birth cohort study to unravel the complex interplay between early-life environmental and genetic risk factors in health and disease: the Chongqing Longitudinal Twin Study (LoTiS). AB - INTRODUCTION: Non-communicable diseases (NCD) now represent the major burden of adverse health in most countries. It is clear that much of the risk of such conditions begins very early in life, potentially in utero. Given their complex aetiology, an understanding of the origins of NCD requires an in-depth analysis of the interplay between genetic variation and environment, preferably over time. For decades, twin studies have played a key role in understanding such traits. Their strength lies in the ability to disentangle genetic and environmental factors that contribute to a phenotype. This is done by comparing genetically identical monozygotic (MZ) with dizygotic twins, who share on average 50% of genetic variation, or by comparing MZ twins within a pair. This study aims to determine the relative contributions of genes and environment to early-onset intermediate phenotypes related to later adult onset disease (such as growth and neurodevelopment) and to identify specific biomarkers and time points for emergence of phenotypes from infancy, largely independent of underlying genetic factors. METHODS/DESIGN: The Chongqing Longitudinal Twin Study (LoTiS) will recruit 300 women pregnant with twins, enriched for MZ pregnancies, with follow up to 3 years of age. Data collection will be undertaken at key time points in gestation (*3), at delivery and postnatally (*9). Maternal and infant biospecimens including blood, urine, hair, nails and buccal swabs along with measures such as fetal scans and body measurements will be collected. Additional information from questionnaires and medical records includes pregnancy, diet, sociodemographics, maternal stress, and infant growth and neurodevelopment. ETHICS AND DISSEMINATION: This study has been approved by the Ethics Committee of Chongqing Medical University (record no: 201530) and has been registered with the Chinese Clinical Trial Registry (registry no: ChiCTR-OOC-16008203). Results of the recruitment and all subsequent analyses will be submitted for publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER: ChiCTR-OOC-16008203; Results. PMID- 29472257 TI - Dementia prevalence in a population at high vascular risk: the Trinidad national survey of ageing and cognition. AB - OBJECTIVE: To investigate the dementia prevalence in a country with high levels of cardiovascular risk factors DESIGN AND METHODS: Older people in Trinidad are recognised to have particularly high levels of cardiovascular risk factors. We carried out a survey in a nationally representative sample of people aged >=70 years using household enumeration. Dementia status was ascertained using standardised interviews and algorithms from the 10/66 schedule and age-specific prevalence were compared with identically defined output from the 10/66 surveys of 16 536 residents in eight other low-income and middle-income countries. RESULTS: Of 1832 participants (77.0% response rate), dementia was present in 442 (23.4%). Prevalences were 12.0% in persons aged 70-74 years, 23.5% at 75-79, 25.8% at 80-84, 41.3% at 85-89 and 54.0% in those aged >=90 years. Prevalence ratios compared with averages from 10/66 surveys in these age groups were 2.2, 2.6, 1.6, 1.7 and 1.6, respectively, and were 2.7, 2.8, 1.7, 1.4 and 0.8, respectively, compared with previously published consensus estimates for the Latin American region. Dementia was significantly associated with reported stroke and diabetes in logistic regression models adjusted for sociodemographic status and other vascular risk factors (OR (95% CI) 4.40 (2.70 to 7.19) and 1.56 (1.20 to 2.03), respectively). Projected national numbers of people with dementia (18 206) were 70%-100% higher than those estimated using most recent regional consensus prevalences. CONCLUSION: In a nation with high levels of vascular risk, dementia prevalence is higher than expected, particularly at the lower end of the 70+ age range. International prevalence projections may need to take into account risk status as well as age structures. PMID- 29472258 TI - Compassionate care intervention for hospital nursing teams caring for older people: a pilot cluster randomised controlled trial. AB - OBJECTIVE: Compassionate care continues to be a focus for national and international attention, but the existing evidence base lacks the experimental methodology necessary to guide the selection of effective interventions for practice. This study aimed to evaluate the Creating Learning Environments for Compassionate Care (CLECC) intervention in improving compassionate care. SETTING: Ward nursing teams (clusters) in two English National Health Service hospitals randomised to intervention (n=4) or control (n=2). Intervention wards comprised two medicines for older people (MOPs) wards and two medical/surgical wards. Control wards were both MOPs. PARTICIPANTS: Data collected from 627 patients and 178 staff. EXCLUSION CRITERIA: reverse barrier nursed, critically ill, palliative or non-English speaking. All other patients and all nursing staff and Health Care Assistant HCAs were invited to participant, agency and bank staff were excluded. INTERVENTION: CLECC, a workplace intervention focused on developing sustainable leadership and work-team practices to support the delivery of compassionate care. CONTROL: No educational activity. PRIMARY AND SECONDARY OUTCOME MEASURES: Primary Quality of Interaction Schedule (QuIS) for observed staff-patient interactions. Secondary-patient-reported evaluations of emotional care in hospital (PEECH); nurse-reported empathy (Jefferson Scale of Empathy). RESULTS: Trial proceeded as per protocol, randomisation was acceptable. Some but not all blinding strategies were successful. QuIS observations achieved 93% recruitment rate with 25% of patient sample cognitively impaired. At follow-up there were more total positive (78% vs 74%) and less total negative (8% vs 11%) QuIS ratings for intervention wards versus control wards. Sixty-three per cent of intervention ward patients scored lowest (ie, more negative) scores on PEECH connection subscale, versus 79% of control. This was not a statistically significant difference. No statistically significant differences in nursing empathy were observed. CONCLUSIONS: Use of experimental methods is feasible. The use of structured observation of staff patient interaction quality is a promising outcome measure inclusive of hard to reach groups. TRIAL REGISTRATION NUMBER: ISRCTN16789770. PMID- 29472259 TI - Feasibility of a multicentre, randomised controlled trial of laparoscopic versus open colorectal surgery in the acute setting: the LaCeS feasibility trial protocol. AB - INTRODUCTION: Acute colorectal surgery forms a significant proportion of emergency admissions within the National Health Service. There is limited evidence to suggest minimally invasive surgery may be associated with improved clinical outcomes in this cohort of patients. Consequently, there is a need to assess the clinical effectiveness and cost-effectiveness of laparoscopic surgery in the acute colorectal setting. However,emergency colorectal surgical trials have previously been difficult to conduct due to issues surrounding recruitment and equipoise. The LaCeS (randomised controlled trial of Laparoscopic versus open Colorectal Surgery in the acute setting) feasibility trial will determine the feasibility of conducting a definitive, phase III trial of laparoscopic versus open acute colorectal resection. METHODS AND ANALYSIS: The LaCeS feasibility trial is a prospective, multicentre, single-blinded, parallel group, pragmatic randomised controlled feasibility trial. Patients will be randomised on a 1:1 basis to receive eitherlaparoscopic or open surgery. The trial aims to recruit at least 66 patients from five acute general surgical units across the UK. Patients over the age of 18 with a diagnosis of acute colorectal pathology requiring resection on clinical and radiological/endoscopic investigations, with a National Confidential Enquiry into Patient Outcome and Death classification of urgent will be considered eligible for participation. The primary outcome is recruitment. Secondary outcomes include assessing the safety profile of laparoscopic surgery using intraoperative and postoperative complication rates, conversion rates and patient-safety indicators as surrogate markers. Clinical and patient-reported outcomes will also be reported. The trial will contain an embedded qualitative study to assess clinician and patient acceptability of trial processes. ETHICS AND DISSEMINATION: The LaCeS feasibility trial is approved by the Yorkshire and The Humber, Bradford Leeds Research Ethics Committee (REC reference: 15/ YH/0542). The results from the trial will be presented at national and international colorectal conferences and will be submitted for publication to peer-reviewed journals.

PMID- 29472260 TI - Exploring the relationship between local food environments and obesity in UK, Ireland, Australia and New Zealand: a systematic review protocol. AB - INTRODUCTION: Obesity is a global pandemic that affects all socioeconomic strata, however, the highest figures have been observed in the most disadvantaged social groups. Evidence from the USA and Canada showed that specific urban settings encourage obesogenic behaviour in the population living and/or working there. We aim to examine the evidence on the association between local food environments and obesity in the UK, Ireland, Australia and New Zealand. METHODS: Six databases from 1990 to 2017 will be searched: MEDLINE (Ovid), Embase (Ovid), Scopus, The Cumulative Index to Nursing and Allied Health Literature (CINAHL), Applied Social Sciences Index and Abstracts (ASSIA) and Web of Science. Grey literature will also be sought by searching Opengrey Europe, The Grey Literature Report and relevant government websites. Additional studies will be retrieved from the reference lists of the selected articles. It will include cohort, longitudinal, case study and cross-sectional studies that have assessed the relationship between local food environments and obesity in the UK, Ireland, Australia and New Zealand regardless of sex, age and ethnicity of the population. Two researchers will independently select the studies and extract the data. Data items will incorporate: author names, title, study design, year of study, year exposure data collected, country, city, urban/rural, age range, study exclusions, special characteristics of study populations, aims, working definitions of food environments and food outlets, exposure and methods of data collection, outcomes and key findings. A narrative synthesis and a summary of the results will be produced separately for children and adults, according to the type of food exposure-outcome. All the selected studies will be assessed using The Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. ETHICS AND DISSEMINATION: This study will be based on published literature, and therefore ethical approval has not been sought. Our findings will be presented at relevant national and international scientific conferences and published in a peer reviewed journal. PMID- 29472261 TI - Development and validation of the Swedish national stroke register Riksstroke's questionnaires in patients at 3 and 12 months after stroke: a qualitative study. AB - OBJECTIVES: Because healthcare and community organisations and treatment methods are always changing, continuous changes might also be needed in questionnaires that register patient-reported outcomes (PRO) and patient-reported experiences (PRE) of healthcare interventions and community support. Thus, the aim of this study was to test the content and face validity, including the readability, of two questionnaires used by the Swedish national stroke register Riksstroke to register PRO and PRE at 3 and 12 months poststroke. DESIGN: Clinicians' and patients' knowledge and experiences of current care, rehabilitation, community support and functioning after stroke as well as comments noted regarding the content and layout of the questionnaires were retrieved in focus-groups with expert clinicians and in patient interviews analysed with content analysis. A workgroup of experts with experience in stroke care, rehabilitation and research repeatedly revised the questionnaires regarding content, layout and consistency throughout the validation process. PARTICIPANTS: The participants included allied healthcare professionals, nurses and physicians with extensive experience of working with stroke care and rehabilitation (expert clinicians) as well as patients who had suffered a stroke 3 or 12 months earlier and who were purposefully selected among those who had completed and returned the 3-month questionnaire. SETTING: Expert clinicians met at their work place in focus groups. Patients were interviewed where they resided, that is, in their home or nursing home, including rural, town and city areas in Sweden. RESULTS: Based on clinical expertise and comments from the patients (n=47), the questionnaires were revised and then found to be valid in terms of content validity and face validity, including readability. CONCLUSIONS: The present evaluation emphasises the need for testing aspects of validity, including readability, of questionnaires addressing PRO and PRE and for the recurrent revision of such questionnaires in order to maintain their validity in a society undergoing constant change. PMID- 29472262 TI - A prospective cohort study to investigate parental stress and child health in low income Chinese families: protocol paper. AB - INTRODUCTION: Chronic stress has adverse effects on health. Adults and children from low-income families are subject to multiple sources of stress. Existing literature about economic hardship mostly focuses on either adults or children but not both. Moreover, there is limited knowledge on the relationship between parental generalised stress and child health problems. This study aims to explore the bidirectional relationship between parental stress and child health in Chinese low-income families and to identify other modifiable factors influencing this relationship. METHODS AND ANALYSIS: This prospective cohort study will sample 254 low-income parent-child pairs and follow them up for 24 months with assessments at three time points (baseline, 12 and 24 months) on parental stress, health-related quality of life (HRQOL) and child health and behaviour using both subjective measures and objective physiological parameters. This study will collect data using standardised measures on HRQOL and behaviours of children as well as on HRQOL, mental health and stress levels of parents along with physiological tests of allostatic load and telomere length. The mediating or moderating effect of family harmony, parenting style and neighbourhood conditions will also be assessed. Data will be analysed using latent growth modelling and cross-lagged path analysis modelling to examine the bidirectional effect of parental stress and child health over time. Mediation and moderation analysis will also be conducted to examine the mechanism by which the variables relate. ETHICS AND DISSEMINATION: This study was approved by the institutional review board of the University of Hong Kong-the Hospital Authority Hong Kong West Cluster, reference no: UW 16-415. The study findings will be disseminated through peer-reviewed publications and international conferences. TRIAL REGISTRATION NUMBER: NCT03185273; Pre-results. PMID- 29472263 TI - Defining a set of standardised outcome measures for newly diagnosed patients with multiple myeloma using the Delphi consensus method: the IMPORTA project. AB - OBJECTIVE: To define a standard set of outcomes and the most appropriate instruments to measure them for managing newly diagnosed patients with multiple myeloma (MM). METHODS: A literature review and five discussion groups facilitated the design of two-round Delphi questionnaire. Delphi panellists (haematologists, hospital pharmacists and patients) were identified by the scientific committee, the Spanish Program of Haematology Treatments Foundation, the Spanish Society of Hospital Pharmacies and the Spanish Community of Patients with MM. Panellist's perception about outcomes' suitability and feasibility of use was assessed on a seven-point Likert scale. Consensus was reached when at least 75% of the respondents reached agreement or disagreement. A scientific committee led the project. RESULTS: Fifty-one and 45 panellists participated in the first and second Delphi rounds, respectively. Consensus was reached to use overall survival, progression-free survival, minimal residual disease and treatment response to assess survival and disease control. Panellists agreed to measure health-related quality of life, pain, performance status, fatigue, psychosocial status, symptoms, self-perception on body image, sexuality and preferences/satisfaction. However, panellist did not reach consensus about the feasibility of assessing in routine practice psychosocial status, symptoms, self perception on body image and sexuality. Consensus was reached to collect patient reported outcomes through the European Organisation for the Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ) Core questionnaire 30 (C30), three items from EORTC-QLQ-Multiple Myeloma (MY20) and EORTC-QLQ-Breast Cancer (BR23), pain Visual Analogue Scale, Morisky-Green and ad hoc questions about patients' preferences/satisfaction. CONCLUSIONS: A consensual standard set of outcomes for managing newly diagnosed patients with MM has been defined. The feasibility of its implementation in routine practice will be assessed in a future pilot study. PMID- 29472264 TI - Cost-effectiveness of mechanical thrombectomy within 6 hours of acute ischaemic stroke in China. AB - OBJECTIVES: Endovascular mechanical thrombectomy is an effective but expensive therapy for acute ischaemic stroke with proximal anterior circulation occlusion. This study aimed to determine the cost-effectiveness of mechanical thrombectomy in China, which is the largest developing country. DESIGN: A combination of decision tree and Markov model was developed. Outcome and cost data were derived from the published literature and claims database. The efficacy data were derived from the meta-analyses of nine trials. One-way and probabilistic sensitivity analyses were performed in order to assess the uncertainty of the results. SETTING: Hospitals in China. PARTICIPANTS: The patients with acute ischaemic stroke caused by proximal anterior circulation occlusion within 6 hours. INTERVENTIONS: Mechanical thrombectomy within 6 hours with intravenous tissue plasminogen activator (tPA) treatment within 4.5 hours versus intravenous tPA treatment alone. OUTCOME MEASURES: The benefit conferred by the treatment was assessed by estimating the cost per quality-adjusted life-year (QALY) gained in the long term (30 years). RESULTS: The addition of mechanical thrombectomy to intravenous tPA treatment compared with standard treatment alone yielded a lifetime gain of 0.794 QALYs at an additional cost of CNY 50 000 (US$7700), resulting in a cost of CNY 63 010 (US$9690) per QALY gained. The probabilistic sensitivity analysis indicated that mechanical thrombectomy was cost-effective in 99.9% of the simulation runs at a willingness-to-pay threshold of CNY 125 700 (US$19 300) per QALY. CONCLUSIONS: Mechanical thrombectomy for acute ischaemic stroke caused by proximal anterior circulation occlusion within 6 hours was cost effective in China. The data may be used as a reference with regard to medical resources allocation for stroke treatment in low-income and middle-income countries as well as in the remote areas in the developed countries. PMID- 29472265 TI - Does early vitamin B12 supplementation improve neurodevelopment and cognitive function in childhood and into school age: a study protocol for extended follow ups from randomised controlled trials in India and Tanzania. AB - INTRODUCTION: As many as 250 million children under the age of 5 may not be reaching their full developmental potential partly due to poor nutrition during pregnancy and the first 2 years of life. Micronutrients, including vitamin B12, are important for the development of brain structure and function; however, the timing, duration and severity of deficiencies may alter the impact on functional development outcomes. Consequently, to fully explore the effect of vitamin B12 on cognitive function, it is crucial to measure neurodevelopment at different ages, in different populations and with vitamin B12 supplementation at different times during the critical periods of neurodevelopment. METHODS AND ANALYSIS: In this project, we follow up children from four recently completed randomised placebo controlled trials of oral vitamin B12 supplementation, two in India and two in Tanzania, to explore the long-term effects on neurodevelopmental outcomes and growth. All the included trials provided at least two recommended dietary allowances of oral vitamin B12 daily for at least 6 months. Vitamin B12 was supplemented either during pregnancy, early infancy or early childhood. Primary outcomes are neurodevelopmental status, cognitive function and growth later in childhood. We apply validated and culturally appropriate instruments to identify relevant developmental outcomes. All statistical analyses will be done according to intention-to-treat principles. The project provides an excellent opportunity to examine the effect of vitamin B12 supplementation in different periods during early life and measure the outcomes later in childhood. ETHICS AND DISSEMINATION: The study has received ethical approvals from all relevant authorities in Norway, USA, Tanzania and India and complies fully with ethical principles for medical research. Results will be presented at national and international research and policy meetings and published in peer-reviewed scientific journals, preferably open access. TRIAL REGISTRATION NUMBER: NCT00641862 (Bangalore); NCT00717730, updated CTRI/2016/11/007494 (Delhi); NCT00197548 and NCT00421668 (Dar es Salaam). PMID- 29472266 TI - Long-term mortality in outpatients with type 2 diabetes in a reference hospital in Cameroon: a retrospective cohort study. AB - OBJECTIVES: There are limited data on mortality in patients with type 2 diabetes mellitus (T2DM) in Sub-Saharan Africa. We aimed at determining the mortality rate, and the causes and the predictors of death in patients with T2DM followed as outpatients in a reference hospital in Cameroon. DESIGN: Retrospective cohort study. SETTING: A reference hospital in Cameroon. PARTICIPANTS: From December 2015 to March 2016, patients with T2DM aged 18 years and older and who consulted between January 2009 and December 2014, were contacted directly or through their next of kin, and included in this study. All participants with less than 75% of desired data in files, those who could not be reached on the phone and those who refused to provide consent were excluded from the study. Of the 940 eligible patients, 628 (352 men and 276 women) were included and completed the study, giving a response rate of 66.8%. OUTCOME MEASURES: Death rate, causes of death and predictors of death. RESULTS: Of the 628 patients (mean age: 56.5 years; median diabetes duration: 3.5 years) followed up for a total of 2161 person years, 54 died, giving a mortality rate of 2.5 per 100 person-years and a cumulative mortality rate of 8.6%. Acute metabolic complications (22.2%), cardiovascular diseases (16.7%), cancers (14.8%), nephropathy (14.8%) and diabetic foot syndrome (13.0%) were the most common causes of death. Advanced age (adjusted HR (aHR) 1.06, 95% CI 1.02 to 1.10; P=0.002), raised glycated haemoglobin (HbA1c) (aHR 1.16, 95% CI 1.00 to 1.35; P=0.051), low blood haemoglobin (aHR 1.06, 95% CI 1.02 to 1.10; P=0.002) and proteinuria (aHR 2.97, 95% CI 1.40 to 6.28; P=0.004) were identified as independent predictors of death. CONCLUSIONS: The mortality rate in patients with T2DM is high in our population, with acute metabolic complications as the leading cause. Patients with advanced age, raised HbA1c, anaemia or proteinuria are at higher risk of death and therefore represent the target of interest to prevent mortality in T2DM. PMID- 29472267 TI - Measurement properties of the craniocervical flexion test: a systematic review protocol. AB - INTRODUCTION: Neck pain is the leading cause of years lived with disability worldwide and it accounts for high economic and societal burden. Altered activation of the neck muscles is a common musculoskeletal impairment presented by patients with neck pain. The craniocervical flexion test with pressure biofeedback unit has been widely used in clinical practice to assess function of deep neck flexor muscles. This systematic review will assess the measurement properties of the craniocervical flexion test for assessing deep cervical flexor muscles. METHODS AND ANALYSIS: This is a protocol for a systematic review that will follow the Preferred Reporting Items for Systematic Review and Meta-Analysis statement. MEDLINE (via PubMed), EMBASE, PEDro, Cochrane Central Register of Controlled Trials (CENTRAL), Scopus and Science Direct will be systematically searched from inception. Studies of any design that have investigated and reported at least one measurement property of the craniocervical flexion test for assessing the deep cervical flexor muscles will be included. All measurement properties will be considered as outcomes. Two reviewers will independently rate the risk of bias of individual studies using the updated COnsensus-based Standards for the selection of health Measurement Instruments risk of bias checklist. A structured narrative synthesis will be used for data analysis. Quantitative findings for each measurement property will be summarised. The overall rating for a measurement property will be classified as 'positive', 'indeterminate' or 'negative'. The overall rating will be accompanied with a level of evidence. ETHICS AND DISSEMINATION: Ethical approval and patient consent are not required since this is a systematic review based on published studies. Findings will be submitted to a peer-reviewed journal for publication. PROSPERO REGISTRATION NUMBER: CRD42017062175. PMID- 29472268 TI - Neuroimaging of headaches in patients with normal neurological examination: protocol for a systematic review. AB - INTRODUCTION: Headache disorders (HD) are among the most frequent neurological disorders seen in neurology practice. Because secondary HD are rare, patients' examination is most often unremarkable. However, the will to relieve patients' anxiety and the fear of prosecutions lead to overuse of neuroimaging thus resulting in the discovery of incidental findings (IF) or normal variants that can lead to futile or harmful procedures. Knowing the probability of identifying a potentially clinically significant lesion in patients with isolated headache could facilitate decision-making and reduce health costs. This review aims to determine the prevalence of incidental findings and normal anatomic variants (NAV) on neuroimaging studies performed in patients presenting with headache and normal neurological examination. METHOD AND ANALYSIS: Studies reporting neuroimaging findings in patients with headache and normal neurological examination and published before the 30 September 2017 will be identified by searching PubMed, Medline and EMBASE (Excerpta Medica Database). Relevant unpublished papers and conference proceedings will also be checked. Full texts of eligible studies will then be accessed and data extracted using a standard data extraction sheet. Studies will be assessed for quality and risk of bias. Heterogeneity of studies will be evaluated by the chi2 test on Cochrane's Q statistic. The prevalence of NAV and IF across studies and in relevant subgroups will be estimated by pooling the study-specific estimates using a random-effects meta-analysis. Visual analysis of funnel plot and Egger's test will be used to detect publication bias. The report of this systematic review will be compliant with the Meta-analysis of Observational Studies in Epidemiology guidelines. ETHICS AND DISSEMINATION: The current study is based on published data; ethical approval is, therefore, not required. The final report of this systematic review will be published in a peer-reviewed journal. Furthermore, findings will be presented at conferences and submitted to relevant health authorities. TRIAL REGISTRATION NUMBER: CRD42017079714. PMID- 29472269 TI - Understanding the gender gap in antibiotic prescribing: a cross-sectional analysis of English primary care. AB - OBJECTIVES: To explore the causes of the gender gap in antibiotic prescribing, and to determine whether women are more likely than men to receive an antibiotic prescription per consultation. DESIGN: Cross-sectional analysis of routinely collected electronic medical records from The Health Improvement Network (THIN). SETTING: English primary care. PARTICIPANTS: Patients who consulted general practices registered with THIN between 2013 and 2015. PRIMARY AND SECONDARY OUTCOME MEASURES: Total antibiotic prescribing was measured in children (<19 years), adults (19-64 years) and the elderly (65+ years). For 12 common conditions, the number of adult consultations was measured, and the relative risk (RR) of being prescribed antibiotics when consulting as female or with comorbidity was estimated. RESULTS: Among 4.57 million antibiotic prescriptions observed in the data, female patients received 67% more prescriptions than male patients, and 43% more when excluding antibiotics used to treat urinary tract infection (UTI). These gaps were more pronounced in adult women (99% more prescriptions than men; 69% more when excluding UTI) than in children (9%; 0%) or the elderly (67%; 38%). Among adults, women accounted for 64% of consultations (62% among patients with comorbidity), but were not substantially more likely than men to receive an antibiotic prescription when consulting with common conditions such as cough (RR 1.01; 95% CI 1.00 to 1.02), sore throat (RR 1.01, 95% CI 1.00 to 1.01) and lower respiratory tract infection (RR 1.00, 95% CI 1.00 to 1.01). Exceptions were skin conditions: women were less likely to be prescribed antibiotics when consulting with acne (RR 0.67, 95% CI 0.66 to 0.69) or impetigo (RR 0.85, 95% CI 0.81 to 0.88). CONCLUSIONS: The gender gap in antibiotic prescribing can largely be explained by consultation behaviour. Although in most cases adult men and women are equally likely to be prescribed an antibiotic when consulting primary care, it is unclear whether or not they are equally indicated for antibiotic therapy. PMID- 29472270 TI - CRISPR RNAs trigger innate immune responses in human cells. AB - Here, we report that CRISPR guide RNAs (gRNAs) with a 5'-triphosphate group (5' ppp gRNAs) produced via in vitro transcription trigger RNA-sensing innate immune responses in human and murine cells, leading to cytotoxicity. 5'-ppp gRNAs in the cytosol are recognized by DDX58, which in turn activates type I interferon responses, causing up to ~80% cell death. We show that the triphosphate group can be removed by a phosphatase in vitro and that the resulting 5'-hydroxyl gRNAs in complex with Cas9 or Cpf1 avoid innate immune responses and can achieve targeted mutagenesis at a frequency of 95% in primary human CD4+ T cells. These results are in line with previous findings that chemically synthesized sgRNAs with a 5' hydroxyl group are much more efficient than in vitro-transcribed (IVT) sgRNAs in human and other mammalian cells. The phosphatase treatment of IVT sgRNAs is a cost-effective method for making highly active sgRNAs, avoiding innate immune responses in human cells. PMID- 29472271 TI - TNFalpha and Radioresistant Stromal Cells Are Essential for Therapeutic Efficacy of Cyclic Dinucleotide STING Agonists in Nonimmunogenic Tumors. AB - The cGAS-STING cytosolic DNA sensing pathway may play an integral role in the initiation of antitumor immune responses. Studies evaluating the immunogenicity of various cyclic dinucleotide (CDN) STING agonists administered by intratumoral (i.t.) injection showed potent induction of inflammation, tumor necrosis, and, in some cases, durable tumor-specific adaptive immunity. However, the specific immune mechanisms underlying these responses remain incompletely defined. The majority of these studies have focused on the effect of CDNs on immune cells but have not conclusively interrogated the role of stromal cells in the acute rejection of the CDN-injected tumor. Here, we revealed a mechanism of STING agonist-mediated tumor response that relied on both stromal and immune cells to achieve tumor regression and clearance. Using knockout and bone marrow chimeric mice, we showed that although bone marrow-derived TNFalpha was necessary for CDN induced necrosis, STING signaling in radioresistant stromal cells was also essential for CDN-mediated tumor rejection. These results provide evidence for crosstalk between stromal and hematopoietic cells during CDN-mediated tumor collapse after i.t. administration. These mechanistic insights may prove critical in the clinical development of STING agonists. Cancer Immunol Res; 6(4); 422-33. (c)2018 AACR.

AB - PURPOSE: The development and implementation of a hospitalwide, pharmacist-led transitions-of-care (TOC) program are described. METHODS: This 21-week quality improvement initiative was conducted from October 1, 2015, to February 26, 2016, at Memorial Hospital Pembroke. A TOC team was comprised of pharmacists, a pharmacy resident, pharmacy students, a physician, case managers, and nurses. All patients over the age of 18 admitted to the inpatient telemetry unit were included in this initiative. The primary endpoint was a sustained improvement in Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) scores for "Communication About Medications" and "Care Transitions: Understood the Purpose of Taking Medications." Secondary outcomes included 90% of admission and 80% of discharge medication reconciliations reviewed by a pharmacist. RESULTS: A total of 661 patients were included. The HCAHPS scores for "Communication About Medications" and "Care Transitions: Understood the Purpose of Taking Medications" had a sustained improvement during the study period. A pharmacist completed 94% and 75% of admission and discharge medication reviews, respectively, and a total of 1,579 interventions were made. Discharge education was completed at a rate of 73%. CONCLUSION: After a quality improvement initiative developed by pharmacists was implemented, HCAHPS scores showed improvement and more patients received medication reconciliation. PMID- 29472273 TI - A unified approach for quantifying and interpreting DNA shape readout by transcription factors. AB - Transcription factors (TFs) interpret DNA sequence by probing the chemical and structural properties of the nucleotide polymer. DNA shape is thought to enable a parsimonious representation of dependencies between nucleotide positions. Here, we propose a unified mathematical representation of the DNA sequence dependence of shape and TF binding, respectively, which simplifies and enhances analysis of shape readout. First, we demonstrate that linear models based on mononucleotide features alone account for 60-70% of the variance in minor groove width, roll, helix twist, and propeller twist. This explains why simple scoring matrices that ignore all dependencies between nucleotide positions can partially account for DNA shape readout by a TF Adding dinucleotide features as sequence-to-shape predictors to our model, we can almost perfectly explain the shape parameters. Building on this observation, we developed a post hoc analysis method that can be used to analyze any mechanism-agnostic protein-DNA binding model in terms of shape readout. Our insights provide an alternative strategy for using DNA shape information to enhance our understanding of how cis-regulatory codes are interpreted by the cellular machinery. PMID- 29472275 TI - Comparison of clinical pharmacy specialists and primary care physicians in treatment of type 2 diabetes mellitus in rural Veterans Affairs facilities. AB - PURPOSE: Results of a study to compare the impact of clinical pharmacy specialist (CPS) interventions with primary care physician (PCP) interventions in veterans with type 2 diabetes mellitus (T2D) in a rural setting are presented. METHODS: A retrospective analysis was performed examining veterans diagnosed with T2D with a glycosylated hemoglobin (HbA1c) of >=8% receiving treatment at a rural community based outpatient clinic associated with the Memphis Veterans Affairs Medical Center. Propensity score matching was used to create a 1:1 cohort of patients managed by physicians or clinical pharmacy specialists. Patients were evaluated as their own control and as compared cohorts. The primary outcome was the difference in HbA1c. Secondary outcomes included changes in total cholesterol, low-density lipoprotein cholesterol, triglycerides, and body mass index. RESULTS: Data were collected from 124 patients (n = 62 CPS patients, n = 62 PCP patients). Baseline HbA1c in the CPS and PCP groups were 10.2% +/- 1.9% and 9.6% +/- 1.6%, respectively. Postintervention HbA1c in the CPS cohort was 7.5% +/- 1.1% (range, 6-11.7%), indicating an absolute reduction of 2.7% (p < 0.001). Postintervention HbA1c in the PCP cohort was 8.5% +/- 1.5% (range, 5.4-12.6%), resulting in an absolute reduction of 1.1% (p < 0.001). The CPS intervention resulted in a greater mean HbA1c absolute reduction of 1.6 percentage points compared to physician intervention (p < 0.001). CONCLUSION: Compared with physician intervention, clinical pharmacy intervention in the treatment of T2D led to a greater mean HbA1c reduction in patients receiving care through VA facilities in rural settings. PMID- 29472276 TI - Using lean methodology to optimize time to antibiotic administration in patients with sepsis. AB - PURPOSE: Results of a study to apply lean methodology to an inpatient pharmacy workflow to optimize timely administration of Centers for Medicare and Medicaid Services (CMS)-approved antibiotics for patients with severe sepsis or septic shock are presented. METHODS: This quasi-experimental study was conducted at an 802-bed institution using lean methodology to assess the inpatient pharmacy workflow for dispensing antibiotics to adult patients. The preintervention and postintervention phases occurred from February to September, 2015, and from October 2015 to May 2016, respectively. Patients were included if they were hospitalized with an intensive care department 9 or 10 code for severe sepsis or septic shock, had an order for a CMS-approved antibiotic, and met clinical criteria for severe sepsis or septic shock. Patients were excluded if they received first-dose antibiotics in the emergency department. The primary outcome was time from CMS-approved antibiotic order entry to medication administration. Secondary outcomes included timeliness of individual workflow dispensing parameters, patient outcomes, and compliance with the newly implemented workflow. RESULTS: A total of 102 patients were included, 54 in the preintervention and 48 in the postintervention group. Baseline demographics between the groups were similar. There was a significant reduction in the median time from order entry to antibiotic administration by 40 minutes (preintervention phase 120 minutes versus postintervention phase 80 minutes, p = 0.014). Time from order verification to administration was significantly reduced. There was no difference in other secondary outcomes. CONCLUSION: Lean methodology was successfully used to reduce time to antibiotic administration, which led to improved compliance with the newly implemented sepsis CMS core measure. PMID- 29472277 TI - Documenting Stage 1 and 2 Meaningful Use criteria: A comparison of clinical pharmacists with other healthcare providers. AB - PURPOSE: Documentation of Stage 1 and Stage 2 Meaningful Use (MU) criteria for patients with type 2 diabetes mellitus between clinical pharmacists and other healthcare providers was compared. METHODS: Patients seen at 8 clinics in a federally qualified health center who had type 2 diabetes mellitus and were seen by clinical pharmacists or other healthcare providers were randomly selected for inclusion in this retrospective study. Approximately half of the encounters were evaluated for Stage 1 MU compliance (encounters from October through December 2014), and half were evaluated for Stage 2 MU compliance (encounters from January through March 2015). Categorical and descriptive variables were analyzed by calculating frequencies and percentages. Chi-square tests were used to compare groups with an a priori level of significance set at 0.05. RESULTS: A total of 790 patients were seen by 46 providers, 8 (18%) of whom were clinical pharmacists. The study also included 24 medical doctors, 8 family nurse practitioners, 1 physician assistant, and 5 doctors of osteopathic medicine. Other healthcare providers more consistently documented 5 Stage 1 MU criteria than did clinical pharmacists. Clinical pharmacists more consistently documented 2 core objectives than did other healthcare providers. Otherwise, no significant differences in documentation were detected. CONCLUSION: Other healthcare providers more consistently documented 5 Stage 1 MU criteria than did clinical pharmacists. Clinical pharmacists more consistently documented 2 core objectives than did other healthcare providers. PMID- 29472279 TI - Comprehensive analysis of the MLH1 promoter region in 480 patients with colorectal cancer and 1150 controls reveals new variants including one with a heritable constitutional MLH1 epimutation. AB - BACKGROUND: Germline defects in MLH1, MSH2, MSH6 and PMS2 predisposing for Lynch syndrome (LS) are mainly based on sequence changes, whereas a constitutional epimutation of MLH1(CEM) is exceptionally rare. This abnormal MLH1 promoter methylation is not hereditary when arising de novo, whereas a stably heritable and variant-induced CEM was described for one single allele. We searched for MLH1 promoter variants causing a germline or somatic methylation induction or transcriptional repression. METHODS: We analysed the MLH1 promoter sequence in five different patient groups with colorectal cancer (CRC) (n=480) composed of patients with i) CEM (n=16), ii) unsolved loss of MLH1 expression in CRC (n=37), iii) CpG-island methylator-phenotype CRC (n=102), iv) patients with LS (n=83) and v) MLH1-proficient CRC (n=242) as controls. 1150 patients with non-LS tumours also served as controls to correctly judge the results. RESULTS: We detected 10 rare MLH1 promoter variants. One novel, complex MLH1 variant c.-63_-58delins18 is present in a patient with CRC with CEM and his sister, both showing a complete allele-specific promoter methylation and transcriptional silencing. The other nine promoter variants detected in 17 individuals were not associated with methylation. For four of these, a normal, biallelic MLH1 expression was found in the patients' cDNA. CONCLUSION: We report the second promoter variant stably inducing a hereditary CEM. Concerning the classification of promoter variants, we discuss contradictory results from the literature for two variants, describe classification discrepancies between existing rules for five variants, suggest the (re-)classification of five promoter variants to (likely) benign and regard four variants as functionally unclear.

AB - The plant cell cycle is tightly regulated by factors that integrate endogenous cues and environmental signals to adapt plant growth to changing conditions. Under drought, cell division in young leaves is blocked by an active mechanism, reducing the evaporative surface and conserving energy resources. The molecular function of cyclin-dependent kinase-inhibitory proteins (CKIs) in regulating the cell cycle has already been well studied, but little is known about their involvement in cell cycle regulation under adverse growth conditions. In this study, we show that the transcript of the CKI gene SIAMESE-RELATED1 (SMR1) is quickly induced under moderate drought in young Arabidopsis (Arabidopsis thaliana) leaves. Functional characterization further revealed that SMR1 inhibits cell division and affects meristem activity, thereby restricting the growth of leaves and roots. Moreover, we demonstrate that SMR1 is a short-lived protein that is degraded by the 26S proteasome after being ubiquitinated by a Cullin-RING E3 ubiquitin ligase. Consequently, overexpression of a more stable variant of the SMR1 protein leads to a much stronger phenotype than overexpression of the native SMR1. Under moderate drought, both the SMR1 transcript and SMR1 protein accumulate. Despite this induction, smr1 mutants do not show overall tolerance to drought stress but do show less growth inhibition of young leaves under drought. Surprisingly, the growth-repressive hormone ethylene promotes SMR1 induction, but the classical drought hormone abscisic acid does not.

PMID- 29472285 TI - Seven days in medicine: 14-20 February 2018. PMID- 29472284 TI - Symbiosis in the microbial world: from ecology to genome evolution. AB - The concept of symbiosis - defined in 1879 by de Bary as 'the living together of unlike organisms' - has a rich and convoluted history in biology. In part, because it questioned the concept of the individual, symbiosis fell largely outside mainstream science and has traditionally received less attention than other research disciplines. This is gradually changing. In nature organisms do not live in isolation but rather interact with, and are impacted by, diverse beings throughout their life histories. Symbiosis is now recognized as a central driver of evolution across the entire tree of life, including, for example, bacterial endosymbionts that provide insects with vital nutrients and the mitochondria that power our own cells. Symbioses between microbes and their multicellular hosts also underpin the ecological success of some of the most productive ecosystems on the planet, including hydrothermal vents and coral reefs. In November 2017, scientists working in fields spanning the life sciences came together at a Company of Biologists' workshop to discuss the origin, maintenance, and long-term implications of symbiosis from the complementary perspectives of cell biology, ecology, evolution and genomics, taking into account both model and non-model organisms. Here, we provide a brief synthesis of the fruitful discussions that transpired. PMID- 29472286 TI - A novel de novo CAPN5 mutation in a patient with inflammatory vitreoretinopathy, hearing loss, and developmental delay. AB - Mutations that activate the protease calpain-5 (CAPN5) cause a nonsyndromic adult onset autoinflammatory eye disease characterized by uveitis, altered synaptic signaling, retinal degeneration, neovascularization, and intraocular fibrosis. We describe a pediatric patient with severe inflammatory vitreoretinopathy accompanied by hearing loss and developmental delay associated with a novel, de novo CAPN5 missense mutation (c.865C>T, p.Arg289Trp) that shows greater hyperactivation of the calpain protease, indicating a genotype-phenotype correlation that links mutation severity to proteolytic activity and the possibility of earlier onset syndromic disease with auditory and neurological abnormalities.

PMID- 29472288 TI - Usefulness of positron emission tomography/computed tomography in patients with valve-tube graft infection. AB - OBJECTIVE: Infection of valved aortic grafts is a rare entity whose diagnosis remains challenging. Positron emission tomography (PET)/CT has become a criterion for the diagnosis of infective endocarditis (IE) in prosthetic valves, but its role on ascending aortic graft infections remains unclear. This study aims to assess the diagnostic value of PET/CT in patients with valved aortic graft infection. METHODS: 12 episodes with a valved aortic graft who had undergone a PET/CT due to suspicion of IE were prospectively included (group I) and compared with five controls free of infection who underwent PET/CT for other reasons (group II). Pathological uptake of 18F-fluorodeoxyglucose (FDG) and its pattern at the prosthetic valve and aortic graft were studied. RESULTS: Diagnosis of IE was confirmed in 9 out of 12 episodes of group I. 18F-FDG uptake was detectable in eight out of nine cases with a final diagnosis of IE. The most repeated pattern of uptake was homogeneous around the valve and heterogeneous around the tube. There was one false-negative study. Of the three patients in which IE was ruled out, there were two false positives and one true negative. In group II, there were three patients with a positive PET/CT study, two of them had active aortitis and the third was considered false positive. CONCLUSIONS: 18F-FDG PET/CT shows high sensitivity in the detection of infected aortic grafts. Thus, this technique should be considered in the diagnostic work-up of patients with suspicion of aortic graft infection. However, further validation of this approach is needed. PMID- 29472290 TI - Coronary heart disease risk associated with the dyslipidaemia of chronic kidney disease. AB - OBJECTIVE: This study sought to characterise the main dyslipidaemic phenotypes present in chronic kidney disease (CKD) and their association with coronary heart disease (CHD) risk. METHODS: Analyses included 6612 individuals in the multiethnic study of atherosclerosis free of CHD at baseline. CKD was defined as an estimated glomerular filtration rate (eGFR) of 15 to <60 mL/min/1.73 m2 (stages 3-4). Principal component analyses were used to characterise the main dyslipidaemic phenotypes of CKD accounting for the correlation among different lipoproteins and lipoprotein particles. CHD was defined as incident myocardial infarction, angina followed by revascularisation, resuscitated cardiac arrest or CHD death. RESULTS: CHD developed in 303 individuals (5%) with eGFR >=60 and in 72 individuals (12%) with CKD (p for difference <0.001). A dyslipidaemic phenotype (principal component 1 (PC1)) consisting of elevations in triglycerides, triglyceride-rich lipoproteins (VLDL particles), small LDL particles and reductions in HDL particles, was more common in those with CKD, compared with those without CKD (p for difference <0.001). This phenotype was also more strongly associated with CHD in those with CKD: adjusted HRs (95% CIs) per SD increase in PC1 1.13 (95% CI 1.00 to 1.27; P=0.05) and 1.51 (95% CI 1.17 to 1.94; P<0.001) in eGFR >=60 and CKD, respectively (P for interaction=0.05). CONCLUSION: In individuals with mainly stage 3 CKD, a dominant lipid phenotype consisting of triglyceride-rich lipoproteins and other closely correlated lipoproteins is strongly associated with CHD risk. Future studies should investigate whether modification of the components of this phenotype leads to a reduction in the CHD burden in individuals with CKD.

PMID- 29472291 TI - Outcomes after surgical coronary artery revascularisation in children with congenital heart disease. AB - OBJECTIVE: Surgical coronary revascularisation in children with congenital heart disease (CHD) is a rare event for which limited information is available. In this study, we review the indications and outcomes of surgical coronary revascularisation from the Pediatric Cardiac Care Consortium, a large US-based multicentre registry of interventions for CHD. METHODS: This is a retrospective cohort study of children (<18 years old) with CHD who underwent surgical coronary revascularisation between 1982 and 2011. In-hospital mortality and graft patency data were obtained from the registry. Long-term transplant-free survival through 2014 was achieved for patients with adequate identifiers via linkage with the US National Death Index and the Organ Procurement and Transplantation Network. RESULTS: Coronary revascularisation was accomplished by bypass grafting (n=72, median age 6.8 years, range 3 days-17.4 years) or other operations (n=65, median age 2.6 years, range 5 days-16.7 years) in 137 patients. Most revascularisations were related to the aortic root (61.3%) or coronary anomalies (27.7%), but 10.9% of them were unrelated to either of them. Twenty in-hospital deaths occurred, 70% of them after urgent 'rescue' revascularisation in association with another operation. Long-term outcomes were available by external linkage for 54 patients surviving to hospital discharge (median follow-up time 15.0 years, max follow-up 29.8 years) with a 15-year transplant-free survival of 91% (95% CI 83% to 99%). CONCLUSIONS: Surgical coronary revascularisation can be performed in children with CHD with acceptable immediate and long-term survival. Outcomes are dependent on indication, with the highest mortality in rescue procedures. PMID- 29472293 TI - Degradation of the endoplasmic reticulum-anchored transcription factor MyRF by the ubiquitin ligase SCFFbxw7 in a manner dependent on the kinase GSK-3. AB - The ubiquitin-proteasome system regulates the abundance of many cellular proteins by mediating their targeted degradation. We previously developed a method differential proteomics-based identification of ubiquitylation substrates (DiPIUS)-for the comprehensive identification of substrates for a given F-box protein subunit of SCF-type ubiquitin ligases. We have now applied DiPIUS to the F-box protein Fbxw7 in three cell lines (mHepa, Neuro2A, and C2C12) and thereby identified myelin regulatory factor (MyRF), an endoplasmic reticulum-anchored transcription factor that is essential for myelination of nerves in the central nervous system, as a candidate substrate of Fbxw7 specifically in mHepa cells. Co immunoprecipitation analysis confirmed that the NH2-terminal cytoplasmic domain of MyRF interacted with Fbxw7 in these cells. Furthermore, an in vitro ubiquitylation assay revealed that MyRF undergoes polyubiquitylation in the presence of purified recombinant SCFFbxw7 In addition, the stability of MyRF in mHepa cells was increased by mutation of a putative phosphodegron sequence or by exposure of the cells to an inhibitor of glycogen synthase kinase-3 (GSK-3). We found that MyRF mRNA is not restricted to the central nervous system but is instead distributed widely among mouse tissues. Furthermore, with the use of RNA sequencing in mHepa cells overexpressing or depleted of MyRF, we identified many novel potential target genes of MyRF. Our results thus suggest that Fbxw7 controls the transcription of MyRF target genes in various tissues through regulation of MyRF protein stability in a manner dependent on MyRF phosphorylation by GSK-3.

PMID- 29472294 TI - Impact of the epoxide hydrolase EphD on the metabolism of mycolic acids in mycobacteria. AB - Mycolic acids are the hallmark of the cell envelope in mycobacteria, which include the important human pathogens Mycobacterium tuberculosis and Mycobacterium leprae Mycolic acids are very long C60-C90 alpha-alkyl beta-hydroxy fatty acids having a variety of functional groups on their hydrocarbon chain that define several mycolate types. Mycobacteria also produce an unusually large number of putative epoxide hydrolases, but the physiological functions of these enzymes are still unclear. Here, we report that the mycobacterial epoxide hydrolase EphD is involved in mycolic acid metabolism. We found that orthologs of EphD from M. tuberculosis and M. smegmatis are functional epoxide hydrolases, cleaving a lipophilic substrate, 9,10-cis-epoxystearic acid, in vitro and forming a vicinal diol. The results of EphD overproduction in M. smegmatis and M. bovis BCG Deltahma strains producing epoxymycolic acids indicated that EphD is involved in the metabolism of these forms of mycolates in both fast- and slow-growing mycobacteria. Moreover, using MALDI-TOF-MS and 1H NMR spectroscopy of mycolic acids and lipids isolated from EphD-overproducing M. smegmatis, we identified new oxygenated mycolic acid species that accumulated during epoxymycolate depletion. Disruption of the ephD gene in M. tuberculosis specifically impaired the synthesis of ketomycolates and caused accumulation of their precursor, hydroxymycolate, indicating either direct or indirect involvement of EphD in ketomycolate biosynthesis. Our results clearly indicate that EphD plays a role in metabolism of oxygenated mycolic acids in mycobacteria. PMID- 29472297 TI - Intraoperative Conebeam CT for Assessment of Intracochlear Positioning of Electrode Arrays in Adult Recipients of Cochlear Implants. AB - BACKGROUND AND PURPOSE: Intraoperative conebeam CT has been introduced into the operating room and provides quick radiologic feedback. This study aimed to investigate its utility in the assessment of the positioning of the electrode array after cochlear implantation. MATERIALS AND METHODS: This was a retrospective study of 51 patients (65 ears) with intraoperative imaging by conebeam CT (O-arm) after cochlear implantation between 2013 and 2017. Correct placement into the cochlea was immediately identified. Positioning assessments were later analyzed with OsiriX software. RESULTS: Intraoperative imaging was quickly performed in all cases. No misplacement into the vestibule or semicircular canals was found. A foldover of the implanted array was identified in 1 patient. Secondary analysis by 2 raters showed excellent agreement on insertion depth angle (intraclass correlation = 0.96, P < .001) and length of insertion of the electrode array (intraclass correlation coefficient = 0.93, P = .04) measurements. The evaluation of the number of extracochlear electrodes was identical between the 2 raters in 78% of cases (Cohen kappa = 0.55, P < .001). The scalar position was inconsistent between raters. When we compared O-arm and high-resolution CT images in 14 cases, the agreement was excellent for insertion depth angle (intraclass correlation coefficient = 0.97, P < .001) and insertion length (intraclass correlation coefficient = 0.98, P < .001), good for the number of extracochlear electrodes (Cohen kappa = 0.63, P = .01), but moderate for the scalar position (Cohen kappa = 0.59, P = .02). CONCLUSIONS: Intraoperative conebeam CT using the O-arm is a safe, rapid, easy, and reliable procedure to immediately identify a misplacement or foldover of an electrode array. The insertion depth angle, insertion length, and number of electrodes inserted can be accurately assessed. PMID- 29472296 TI - Brain Injury Lesion Imaging Using Preconditioned Quantitative Susceptibility Mapping without Skull Stripping. AB - BACKGROUND AND PURPOSE: Identifying cerebral microhemorrhage burden can aid in the diagnosis and management of traumatic brain injury, stroke, hypertension, and cerebral amyloid angiopathy. MR imaging susceptibility-based methods are more sensitive than CT for detecting cerebral microhemorrhage, but methods other than quantitative susceptibility mapping provide results that vary with field strength and TE, require additional phase maps to distinguish blood from calcification, and depict cerebral microhemorrhages as bloom artifacts. Quantitative susceptibility mapping provides universal quantification of tissue magnetic property without these constraints but traditionally requires a mask generated by skull-stripping, which can pose challenges at tissue interphases. We evaluated the preconditioned quantitative susceptibility mapping MR imaging method, which does not require skull-stripping, for improved depiction of brain parenchyma and pathology. MATERIALS AND METHODS: Fifty-six subjects underwent brain MR imaging with a 3D multiecho gradient recalled echo acquisition. Mask-based quantitative susceptibility mapping images were created using a commonly used mask-based quantitative susceptibility mapping method, and preconditioned quantitative susceptibility images were made using precondition-based total field inversion. All images were reviewed by a neuroradiologist and a radiology resident. RESULTS: Ten subjects (18%), all with traumatic brain injury, demonstrated blood products on 3D gradient recalled echo imaging. All lesions were visible on preconditioned quantitative susceptibility mapping, while 6 were not visible on mask-based quantitative susceptibility mapping. Thirty-one subjects (55%) demonstrated brain parenchyma and/or lesions that were visible on preconditioned quantitative susceptibility mapping but not on mask-based quantitative susceptibility mapping. Six subjects (11%) demonstrated pons artifacts on preconditioned quantitative susceptibility mapping and mask-based quantitative susceptibility mapping; they were worse on preconditioned quantitative susceptibility mapping. CONCLUSIONS: Preconditioned quantitative susceptibility mapping MR imaging can bring the benefits of quantitative susceptibility mapping imaging to clinical practice without the limitations of mask-based quantitative susceptibility mapping, especially for evaluating cerebral microhemorrhage-associated pathologies, such as traumatic brain injury. PMID- 29472298 TI - Sonographic Development of the Pericallosal Vascularization in the First and Early Second Trimester of Pregnancy. AB - BACKGROUND AND PURPOSE: Anomalies of the corpus callosum are rare. Routine scanning in midtrimester of the pregnancy often fails to identify defective development. The purpose of the study was to identify the pericallosal artery and all its main branching arteries during early gestation from the first trimester onward, to measure the length of the pericallosal artery during its development, and to establish a normal vascular map for each week of development. MATERIALS AND METHODS: We performed a single-center prospective, longitudinal clinical study in 15 patients between 11 and 22 weeks of gestation. The origin and course of the different blood vessels were identified. RESULTS: There was a linear association among gestational age, the biparietal diameter, and the length of the pericallosal artery. The curvature of the developing pericallosal artery increases linearly with the gestational age and biparietal diameter, and 4 variations of branching of the callosomarginal artery were observed. CONCLUSIONS: The pericallosal artery and its branches can be identified and measured from 11 weeks on, and the pericallosal artery takes its characteristic course. A defective course or an abnormal biometry of the pericallosal artery could be an early sonographic marker of abnormal development of the corpus callosum. PMID- 29472299 TI - Evaluation of the Sensitivity of Inhomogeneous Magnetization Transfer (ihMT) MRI for Multiple Sclerosis. AB - BACKGROUND AND PURPOSE: Inhomogeneous magnetization transfer is a new endogenous MR imaging contrast mechanism that has demonstrated high specificity for myelin. Here, we tested the hypothesis that inhomogeneous magnetization transfer is sensitive to pathology in a population of patients with relapsing-remitting MS in a way that both differs from and complements conventional magnetization transfer. MATERIALS AND METHODS: Twenty-five patients with relapsing-remitting MS and 20 healthy volunteers were enrolled in a prospective MR imaging research study, whose protocol included anatomic imaging, standard magnetization transfer, and inhomogeneous magnetization transfer imaging. Magnetization transfer and inhomogeneous magnetization transfer ratios measured in normal-appearing brain tissue and in MS lesions of patients were compared with values measured in control subjects. The potential association of inhomogeneous magnetization transfer ratio variations with the clinical scores (Expanded Disability Status Scale) of patients was further evaluated. RESULTS: The magnetization transfer ratio and inhomogeneous magnetization transfer ratio measured in the thalami and frontal, occipital, and temporal WM of patients with MS were lower compared with those of controls (P < .05). The mean inhomogeneous magnetization transfer ratio measured in lesions was lower than that in normal-appearing WM (P < .05). Significant (P < .05) negative correlations were found between the clinical scores and inhomogeneous magnetization transfer ratio measured in normal appearing WM structures. Weaker nonsignificant correlation trends were found for the magnetization transfer ratio. CONCLUSIONS: The sensitivity of the inhomogeneous magnetization transfer technique for MS was highlighted by the reduction in the inhomogeneous magnetization transfer ratio in MS lesions and in normal-appearing WM of patients compared with controls. Stronger correlations with the Expanded Disability Status Scale score were obtained with the inhomogeneous magnetization transfer ratio compared with the standard magnetization transfer ratio, which may be explained by the higher specificity of inhomogeneous magnetization transfer for myelin. PMID- 29472301 TI - Revenue Increase following 2017 Multiple Procedures Payment Reduction Modification: Differential Impact on Neuroradiology-Report from an Academic Medical Center. AB - BACKGROUND AND PURPOSE: The Centers for Medicare and Medicaid Services imposed a 25% professional component multiple procedure payment reduction for the professional component of advanced diagnostic imaging modalities in January 2012. In 2017, the Centers for Medicare and Medicaid Services rolled back the multiple procedure payment reduction to 5% for subsequent imaging. To evaluate the effect of this change, we analyzed 5 months of Centers for Medicare and Medicaid Services procedures at Johns Hopkins Medical Institution. MATERIALS AND METHODS: We analyzed the procedure codes and reimbursement rate for studies performed between January 1 and May 31, 2017. Patients with Medicare insurance who had multiple diagnostic procedures in a day were selected. Per the Centers for Medicare and Medicaid Services guidelines, procedures with the highest price were considered fully reimbursed and subsequent studies were marked for differences between 25% (2013-2016) and 5% reduction (2017). RESULTS: We included 8787 patients with 22,236 procedures (mean, 2.53 studies/day). CT, MR imaging, and ultrasound scans composed 75.9%, 21.5%, and 2.6% of all studies, with 61.2%, 54.9%, and 85.4% of the procedures of each technique subject to multiple procedure payment reduction, respectively. The projected reimbursement for these studies was $1,666,437, which translated to a $179,782 (12.1%) increase in revenue comparing 25%-versus-5% multiple procedure payment reduction rates for 5 months: $128,542 for CT, $47,802 for MR imaging, and $3439 for ultrasound. The annual overall prorated increase in revenue would be $431,476. The impact was maximal for neuroradiology. CONCLUSIONS: With the recent favorable adjustment in multiple procedure payment reduction regulations, CT-heavy subspecialties like neuroradiology benefit the most with revenue increases. Different practice settings might experience revenue increases to a different extent, depending on the procedure and payer mix.

Lesion count, which encapsulates the natural history of lesion formation and is thought to provide complementary information, is difficult to assess in patients with confluent (ie, spatially overlapping) lesions. We introduce a statistical technique for cross-sectionally counting pathologically distinct lesions. MATERIALS AND METHODS: MR imaging was used to assess the probability of a lesion at each location. The texture of this map was quantified using a novel technique, and clusters resembling the center of a lesion were counted. Validity compared with a criterion standard count was demonstrated in 60 subjects observed longitudinally, and reliability was determined using 14 scans of a clinically stable subject acquired at 7 sites. RESULTS: The proposed count and the criterion standard count were highly correlated (r = 0.97, P < .001) and not significantly different (t59 = -.83, P = .41), and the variability of the proposed count across repeat scans was equivalent to that of lesion load. After accounting for lesion load and age, lesion count was negatively associated (t58 = -2.73, P < .01) with the Expanded Disability Status Scale. Average lesion size had a higher association with the Expanded Disability Status Scale (r = 0.35, P < .01) than lesion load (r = 0.10, P = .44) or lesion count (r = -.12, P = .36) alone. CONCLUSIONS: This study introduces a novel technique for counting pathologically distinct lesions using cross-sectional data and demonstrates its ability to recover obscured longitudinal information. The proposed count allows more accurate estimation of lesion size, which correlated more closely with disability scores than either lesion load or lesion count alone. PMID- 29472302 TI - Quantification of Intracranial Aneurysm Volume Pulsation with 7T MRI. AB - BACKGROUND AND PURPOSE: Aneurysm volume pulsation is a potential predictor of intracranial aneurysm rupture. We evaluated whether 7T MR imaging can quantify aneurysm volume pulsation. MATERIALS AND METHODS: In Stage I of the study, 10 unruptured aneurysms in 9 patients were studied using a high-resolution (0.6-mm, isotropic) 3D gradient-echo sequence with cardiac gating. Semiautomatic segmentation was used to measure aneurysm volume (in cubic millimeters) per cardiac phase. Aneurysm pulsation was defined as the relative increase in volume between the phase with the smallest volume and the phase with the largest volume. The accuracy and precision of the measured volume pulsations were addressed by digital phantom simulations and a repeat image analysis. In Stage II, the imaging protocol was optimized and 9 patients with 9 aneurysms were studied with and without administration of a contrast agent. RESULTS: The mean aneurysm pulsation in Stage I was 8% +/- 7% (range, 2%-27%), with a mean volume change of 15 +/- 14 mm3 (range, 3-51 mm3). The mean difference in volume change for the repeat image analysis was 2 +/- 6 mm3. The artifactual volume pulsations measured with the digital phantom simulations were of the same magnitude as the volume pulsations observed in the patient data, even after protocol optimization in Stage II. CONCLUSIONS: Volume pulsation quantification with the current imaging protocol on 7T MR imaging is not accurate due to multiple imaging artifacts. Future studies should always include aneurysm-specific accuracy analysis. PMID- 29472303 TI - HARMless: Transient Cortical and Sulcal Hyperintensity on Gadolinium-Enhanced FLAIR after Elective Endovascular Coiling of Intracranial Aneurysms. AB - BACKGROUND AND PURPOSE: Cortical and sulcal hyperintensity on gadolinium-enhanced FLAIR has been increasingly recognized after iodinated contrast medium exposure during angiographic procedures. The goal of this study was to assess the relationship of cortical and sulcal hyperintensity on gadolinium-enhanced FLAIR against various variables in patients following elective endovascular treatment of intracranial aneurysms. MATERIALS AND METHODS: We performed a retrospective review of 58 patients with 62 MR imaging studies performed within 72 hours following endovascular treatment of intracranial aneurysms. Patient demographics, aneurysm location, and vascular territory distribution of cortical and sulcal hyperintensity on gadolinium-enhanced FLAIR were documented. Analysis of cortical and sulcal hyperintensity on gadolinium-enhanced FLAIR with iodinated contrast medium volume, procedural duration, number of angiographic runs, and DWI lesions was performed. RESULTS: Cortical and sulcal hyperintensity on gadolinium-enhanced FLAIR was found in 32/62 (51.61%) post-endovascular treatment MR imaging studies, with complete resolution of findings in all patients on the available follow-up studies (27/27). Angiographic iodinated contrast medium injection and arterial anatomy matched the vascular distribution of cortical and sulcal hyperintensity on gadolinium-enhanced FLAIR. No significant association was found between cortical and sulcal hyperintensity on gadolinium-enhanced FLAIR with iodinated contrast medium volume (P = .56 value) and the presence of DWI lesions (P = .68). However, a significant association was found with procedural time (P = .001) and the number of angiographic runs (P = .019). No adverse clinical outcomes were documented. CONCLUSIONS: Cortical and sulcal hyperintensity on gadolinium enhanced FLAIR is a transient observation in the arterial territory exposed to iodinated contrast medium during endovascular treatment of intracranial aneurysms. Cortical and sulcal hyperintensity on gadolinium-enhanced FLAIR is significantly associated with procedural time, and the frequency of angiographic runs suggesting a potential technical influence on the breakdown of the BBB, but no reported adverse clinical outcome or association with both iodinated contrast medium volume and DWI lesions was found. Recognition of cortical and sulcal hyperintensity on gadolinium-enhanced FLAIR as a benign incidental finding is vital to avoid unnecessary investigation. PMID- 29472304 TI - Responsive Designed Interventions Are Needed to Support Positive Outcomes of Children and Adolescents with CKD. PMID- 29472305 TI - Metabolic and Hypertensive Complications of Pregnancy in Women with Nephrolithiasis. AB - BACKGROUND AND OBJECTIVES: Kidney stones are associated with future development of hypertension, diabetes, and the metabolic syndrome. Our objective was to assess whether stone formation before pregnancy was associated with metabolic and hypertensive complications in pregnancy. We hypothesized that stone formation is a marker of metabolic disease and would be associated with higher risk for maternal complications in pregnancy. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We conducted a retrospective cohort study of women who delivered infants at the Massachusetts General Hospital from 2006 to 2015. Women with abdominal imaging (computed tomography or ultrasound) before pregnancy were included in the analysis. Pregnancy outcomes in women with documented kidney stones on imaging (stone formers, n=166) were compared with those of women without stones on imaging (controls, n=1264). Women with preexisting CKD, hypertension, and diabetes were excluded. RESULTS: Gestational diabetes and preeclampsia were more common in stone formers than nonstone formers (18% versus 6%, respectively; P<0.001 and 16% versus 8%, respectively; P=0.002). After multivariable adjustment, previous nephrolithiasis was associated with higher risks of gestational diabetes (adjusted odds ratio, 3.1; 95% confidence interval, 1.8 to 5.3) and preeclampsia (adjusted odds ratio, 2.2; 95% confidence interval, 1.3 to 3.6). Infants of stone formers were born earlier (38.7+/-2.0 versus 39.2+/ 1.7 weeks, respectively; P=0.01); however, rates of small for gestational age offspring and neonatal intensive care admission were similar between groups (8% versus 7%, respectively; P=0.33 and 10% versus 6%, respectively; P=0.08). First trimester body mass index significantly influenced the association between stone disease and hypertensive complications of pregnancy: in a multivariable linear regression model, stone formation acted as an effect modifier of the relationship between maximum systolic BP in the third trimester and body mass index (P interaction <0.001). CONCLUSIONS: In women without preexisting diabetes, hypertension, and CKD, a history of nephrolithiasis was associated with gestational diabetes and hypertensive disorders of pregnancy, especially in women with high first trimester body mass index. PMID- 29472306 TI - Neurocognitive and Educational Outcomes in Children and Adolescents with CKD: A Systematic Review and Meta-Analysis. AB - BACKGROUND AND OBJECTIVES: Poor cognition can affect educational attainment, but the extent of neurocognitive impairment in children with CKD is not well understood. This systematic review assessed global and domain-specific cognition and academic skills in children with CKD and whether these outcomes varied with CKD stage. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Electronic databases were searched for observational studies of children with CKD ages 21 years old or younger that assessed neurocognitive or educational outcomes. Risk of bias was assessed using a modified Newcastle-Ottawa scale. We used random effects models and expressed the estimates as mean differences with 95% confidence intervals stratified by CKD stage. RESULTS: Thirty-four studies (25 cross-sectional, n=2095; nine cohort, n=991) were included. The overall risk of bias was high because of selection and measurement biases. The global cognition (full-scale intelligence quotient) of children with CKD was classified as low average. Compared with the general population, the mean differences (95% confidence intervals) in full-scale intelligence quotient were -10.5 (95% confidence interval, -13.2 to -7.72; all CKD stages, n=758), -9.39 (95% confidence interval, -12.6 to -6.18; mild to moderate stage CKD, n=582), -16.2 (95% confidence interval, -33.2 to 0.86; dialysis, n=23), and -11.2 (95% confidence interval, 17.8 to -4.50; transplant, n=153). Direct comparisons showed that children with mild to moderate stage CKD and kidney transplants scored 11.2 (95% confidence interval, 2.98 to 19.4) and 10.1 (95% confidence interval, -1.81 to 22.0) full scale intelligence quotient points higher than children on dialysis. Children with CKD also had lower scores than the general population in executive function and memory (verbal and visual) domains. Compared with children without CKD, the mean differences in academic skills (n=518) ranged from -15.7 to -1.22 for mathematics, from -9.04 to -0.17 for reading, and from -14.2 to 2.53 for spelling. CONCLUSIONS: Children with CKD may have low-average cognition compared with the general population, with mild deficits observed across academic skills, executive function, and visual and verbal memory. Limited evidence suggests that children on dialysis may be at greatest risk compared with children with mild to moderate stage CKD and transplant recipients. PMID- 29472307 TI - A Genome-Wide Association Study for Host Resistance to Ostreid Herpesvirus in Pacific Oysters (Crassostrea gigas). AB - Ostreid herpesvirus (OsHV) can cause mass mortality events in Pacific oyster aquaculture. While various factors impact on the severity of outbreaks, it is clear that genetic resistance of the host is an important determinant of mortality levels. This raises the possibility of selective breeding strategies to improve the genetic resistance of farmed oyster stocks, thereby contributing to disease control. Traditional selective breeding can be augmented by use of genetic markers, either via marker-assisted or genomic selection. The aim of the current study was to investigate the genetic architecture of resistance to OsHV in Pacific oyster, to identify genomic regions containing putative resistance genes, and to inform the use of genomics to enhance efforts to breed for resistance. To achieve this, a population of ~1,000 juvenile oysters were experimentally challenged with a virulent form of OsHV, with samples taken from mortalities and survivors for genotyping and qPCR measurement of viral load. The samples were genotyped using a recently-developed SNP array, and the genotype data were used to reconstruct the pedigree. Using these pedigree and genotype data, the first high density linkage map was constructed for Pacific oyster, containing 20,353 SNPs mapped to the ten pairs of chromosomes. Genetic parameters for resistance to OsHV were estimated, indicating a significant but low heritability for the binary trait of survival and also for viral load measures (h2 0.12 - 0.25). A genome-wide association study highlighted a region of linkage group 6 containing a significant QTL affecting host resistance. These results are an important step toward identification of genes underlying resistance to OsHV in oyster, and a step toward applying genomic data to enhance selective breeding for disease resistance in oyster aquaculture. PMID- 29472308 TI - Systematic Complex Haploinsufficiency-Based Genetic Analysis of Candida albicans Transcription Factors: Tools and Applications to Virulence-Associated Phenotypes. AB - Genetic interaction analysis is a powerful approach to the study of complex biological processes that are dependent on multiple genes. Because of the largely diploid nature of the human fungal pathogen Candida albicans, genetic interaction analysis has been limited to a small number of large-scale screens and a handful for gene-by-gene studies. Complex haploinsufficiency, which occurs when a strain containing two heterozygous mutations at distinct loci shows a phenotype that is distinct from either of the corresponding single heterozygous mutants, is an expedient approach to genetic interactions analysis in diploid organisms. Here, we describe the construction of a barcoded-library of 133 heterozygous TF deletion mutants and deletion cassettes for designed to facilitate complex haploinsufficiency-based genetic interaction studies of the TF networks in C. albicans We have characterized the phenotypes of these heterozygous mutants under a broad range of in vitro conditions using both agar-plate and pooled signature tag-based assays. Consistent with previous studies, haploinsufficiency is relative uncommon. In contrast, a set of 12 TFs enriched in mutants with a role in adhesion were found to have altered competitive fitness at early time points in a murine model of disseminated candidiasis. Finally, we characterized the genetic interactions of a set of biofilm related TFs in the first two steps of biofilm formation, adherence and filamentation of adherent cells. The genetic interaction networks at each stage of biofilm formation are significantly different indicating that the network is not static but dynamic. PMID- 29472309 TI - Photosensitive Alternative Splicing of the Circadian Clock Gene timeless Is Population Specific in a Cold-Adapted Fly, Drosophila montana. AB - To function properly, organisms must adjust their physiology, behavior and metabolism in response to a suite of varying environmental conditions. One of the central regulators of these changes is organisms' internal circadian clock, and recent evidence has suggested that the clock genes are also important in the regulation of seasonal adjustments. In particular, thermosensitive splicing of the core clock gene timeless in a cosmopolitan fly, Drosophila melanogaster, has implicated this gene to be involved in thermal adaptation. To further investigate this link we examined the splicing of timeless in a northern malt fly species, Drosophila montana, which can withstand much colder climatic conditions than its southern relative. We studied northern and southern populations from two different continents (North America and Europe) to find out whether and how the splicing of this gene varies in response to different temperatures and day lengths. Interestingly, we found that the expression of timeless splice variants was sensitive to differences in light conditions, and while the flies of all study populations showed a change in the usage of splice variants in constant light compared to LD 22:2, the direction of the shift varied between populations. Overall, our findings suggest that the splicing of timeless in northern Drosophila montana flies is photosensitive, rather than thermosensitive and highlights the value of studying multiple species and populations in order to gain perspective on the generality of gene function changes in different kinds of environmental conditions. PMID- 29472310 TI - Temozolomide Plus Bevacizumab in Elderly Patients with Newly Diagnosed Glioblastoma and Poor Performance Status: An ANOCEF Phase II Trial (ATAG). AB - LESSONS LEARNED: Results suggest that the combination of bevacizumab plus temozolomide is active in terms of response rate, survival, performance, quality of life, and cognition in elderly patients with glioblastoma multiforme with poor performance status.Whether this combination is superior to temozolomide alone remains to be demonstrated by a randomized study. BACKGROUND: The optimal treatment of glioblastoma multiforme (GBM) in patients aged >=70 years with a Karnofsky performance status (KPS) <70 is not established. This clinical trial evaluated the efficacy and safety of upfront temozolomide (TMZ) and bevacizumab (Bev) in patients aged >=70 years and a KPS <70. MATERIALS AND METHODS: Patients aged >=70 years with a KPS <70 and biopsy-proven GBM were eligible for this multicenter, prospective, nonrandomized, phase II trial of older patients with impaired performance status. Treatment consisted of TMZ administered at 130-150 mg/m2 per day for 5 days every 4 weeks plus Bev administered at 10 mg/kg every 2 weeks. RESULTS: The trial included 66 patients (median age of 76 years; median KPS of 60). The median overall survival (OS) was 23.9 weeks (95% confidence interval [CI], 19-27.6), and the median progression-free survival (PFS) was 15.3 weeks (95% CI, 12.9-19.3). Twenty-two (33%) patients became transiently capable of self-care (i.e., KPS >70). Cognition and quality of life significantly improved over time during treatment. Grade >=3 hematological adverse events occurred in 13 (20%) patients, high blood pressure in 16 (24%), venous thromboembolism in 3 (4.5%), cerebral hemorrhage in 2 (3%), and intestinal perforation in 2 (3%). CONCLUSION: This study suggests that TMZ + Bev treatment is active in elderly patients with GBM with low KPS and has an acceptable tolerance level.

PMID- 29472312 TI - Complete Remission Following Pembrolizumab in a Woman with Mismatch Repair Deficient Endometrial Cancer and a Germline BRCA1 Mutation. AB - : Endometrial cancer is the most common gynecologic malignancy in the U.S. and, although the majority of cases present at an early stage and can be treated with curative intent, those who present with advanced disease, or develop metastatic or recurrent disease, have a poorer prognosis. A subset of endometrial cancers exhibit mismatch repair (MMR) deficiency. It is now recognized that MMR-deficient cancers are particularly susceptible to programmed cell death protein 1 (PD 1)/programmed death-ligand 1 (PD-L1) inhibitors, and in a landmark judgement in 2017, the U.S. Food and Drug Administration granted accelerated approval to pembrolizumab for these tumors, the first tumor-agnostic approval of a drug. However, less is known about the sensitivity to PD-1 blockade among patients with known mutations in double-strand break DNA repair pathways involving homologous recombination, such as those in BRCA1 or BRCA2. Here we report a case of a patient with an aggressive somatic MMR-deficient endometrial cancer and a germline BRCA1 who experienced a rapid complete remission to pembrolizumab. KEY POINTS: Endometrial cancers, and in particular endometrioid carcinomas, should undergo immunohistochemical testing for mismatch repair proteins.Uterine cancers with documented mismatch repair deficiency are candidates for treatment with programmed cell death protein 1 inhibition.Genomic testing of recurrent, advanced, or metastatic tumors may be useful to determine whether patients are candidates for precision therapies. PMID- 29472313 TI - Luminal A Breast Cancer and Molecular Assays: A Review. AB - PURPOSE: Chemotherapy has been the historical mainstay of treatment for patients with breast cancer, with immunohistochemical markers and tumor characteristics driving treatment decisions. The discovery of different intrinsic subtypes of breast cancer has advanced the understanding of breast cancer, with gene-based assays shedding further light on tumor behavior and response to treatment. DESIGN: This review focuses on the landscape of the luminal A subtype, its definition based on immunohistochemistry (IHC) and gene assays, the prognostic and predictive value of these assays, guideline recommendations, and treatment implications. RESULTS: Clinical studies of the prognostic value of gene-based and IHC-based assays in patients with luminal A-subtype breast cancers suggest a better prognosis for these patients compared with those with breast cancers of other subtypes. CONCLUSION: In today's era of precision medicine, the best treatment regimen for patients with luminal A-subtype tumors is still undetermined, but available data raise the question whether chemotherapy can be omitted and endocrine therapy alone is sufficient for this patient population. IMPLICATIONS FOR PRACTICE: Immunohistochemical markers have traditionally guided treatment decisions in breast cancer. However, advances in gene-expression profiling and availability of gene-based assays have launched these newer tests into everyday clinical practice. Luminal A-subtype tumors are a unique subset that may have favorable tumor biology. Properly defining this tumor subtype is important and may identify a subset of patients for whom endocrine therapy alone is sufficient. PMID- 29472314 TI - Cysteine modifiers suggest an allosteric inhibitory site on the CAL PDZ domain. AB - Protein-protein interactions have become attractive targets for both experimental and therapeutic interventions. The PSD-95/Dlg1/ZO-1 (PDZ) domain is found in a large family of eukaryotic scaffold proteins that plays important roles in intracellular trafficking and localization of many target proteins. Here, we seek inhibitors of the PDZ protein that facilitates post-endocytic degradation of the cystic fibrosis (CF) transmembrane conductance regulator (CFTR): the CFTR associated ligand (CAL). We develop and validate biochemical screens and identify methyl-3,4-dephostatin (MD) and its analog ethyl-3,4-dephostatin (ED) as CAL PDZ inhibitors. Depending on conditions, MD can bind either covalently or non covalently. Crystallographic and NMR data confirm that MD attacks a pocket at a site distinct from the canonical peptide-binding groove, and suggests an allosteric connection between target residue Cys319 and the conserved Leu291 in the GLGI motif. MD and ED thus appear to represent the first examples of small molecule allosteric regulation of PDZ:peptide affinity. Their mechanism of action may exploit the known conformational plasticity of the PDZ domains and suggests that allosteric modulation may represent a strategy for targeting of this family of protein-protein binding modules.

AB - Aquaporins (AQPs), a family of transmembrane channel, are composed of 13 identified members (AQP0-12). Accumulating evidences reported that AQPs were correlated with various biological roles and represented a prognostic predictor in various cancer types. However, the prognostic value of AQPs expression in ovarian cancer remains unclear. Using 'Kaplan-Meier plotter' (KM plotter) online database, we explored the predictive prognostic value of individual AQPs members' mRNA expression to overall survival (OS) in different clinical data, such as histology, pathological grades, clinical stages, TP53 status, and applied chemotherapy in ovarian cancer patients. Our results revealed that higher AQP0, AQP1, and AQP4 mRNA expression were correlated with poor OS, whereas higher AQP3, AQP5, AQP6, AQP8, AQP10, and AQP11 showed better OS in ovarian cancer patients. Moreover, AQP4 and AQP8 showed poor OS in TP53-mutated ovarian cancer patients and AQP1 presented unfavorable OS in both TP53 mutated and wild ovarian cancer patients. Additionally, AQP3, AQP6, and AQP11 mRNA expression were correlated with better OS, whereas AQP0 and AQP1 showed poor OS in all ovarian cancer patients treated with Platin, Taxol, and Taxol + Platin chemotherapy. AQP5, AQP8, and AQP10 were associated with improved OS, however, AQP4 predicted unfavorable OS in all patients treated with Platin chemotherapy. Our results suggest that individual AQPs, except AQP2 and AQP9, are associated with unique prognostic significance and may thus act as new predictive prognostic indicators and potential drug therapeutic target in ovarian cancer. PMID- 29472317 TI - Dynamic Control of Chromosome Topology and Gene Expression by a Chromatin Modification. AB - The function of chromatin modification in establishing higher-order chromosome structure during gene regulation has been elusive. We dissected the machinery and mechanism underlying the enrichment of histone modification H4K20me1 on hermaphrodite X chromosomes during Caenorhabditis elegans dosage compensation and discovered a key role for H4K20me1 in regulating X-chromosome topology and chromosome-wide gene expression. Structural and functional analysis of the dosage compensation complex (DCC) subunit DPY-21 revealed a novel Jumonji C demethylase subfamily that converts H4K20me2 to H4K20me1 in worms and mammals. Inactivation of demethylase activity in vivo by genome editing eliminated H4K20me1 enrichment on X chromosomes of somatic cells, increased X-linked gene expression, reduced X chromosome compaction, and disrupted X-chromosome conformation by diminishing the formation of topologically associated domains. H4K20me1 is also enriched on the inactive X of female mice, making our studies directly relevant to mammalian development. Unexpectedly, DPY-21 also associates specifically with autosomes of nematode germ cells in a DCC-independent manner to enrich H4K20me1 and trigger chromosome compaction. Thus, DPY-21 is an adaptable chromatin regulator. Its H4K20me2 demethylase activity can be harnessed during development for distinct biological functions by targeting it to diverse genomic locations through different mechanisms. In both somatic cells and germ cells, H4K20me1 enrichment modulates three-dimensional chromosome architecture, demonstrating the direct link between chromatin modification and higher-order chromosome structure.

PMID- 29472318 TI - Fork Protection and Therapy Resistance in Hereditary Breast Cancer. AB - The BRCA-Fanconi anemia (FA) pathway preserves the genome and suppresses cancer and is a main determinant of chemotherapeutic efficacy. The hereditary breast cancer genes BRCA1 and BRCA2 function in DNA double-strand break repair mediating distinct steps of homologous recombination (HR). More recently, independent of DNA repair, functions in the replication stress response have come to light, providing insight as to how the BRCA-FA pathway also balances genome preservation with proliferation. The BRCA-FA proteins associate with the replisome and contribute to the efficiency and recovery of replication following perturbations that slow or arrest DNA replication. Although the full repertoire of functions in the replication stress response remains to be elucidated, the function of BRCA1 and BRCA2 in protecting stalled replication forks contributes along with HR to the sensitivity of BRCA-associated tumors to chemotherapy. Moreover, chemoresistance evolves from restoration of either HR and/or fork protection. Although mechanisms underlying the restoration of HR have been characterized, it remains less clear how restoration of fork protection is achieved. Here, we outline mechanisms of "rewired" fork protection and chemotherapy resistance in BRCA cancer. We propose that mechanisms are linked to permissive replication that limits fork remodeling and therefore opportunities for fork degradation. Combating this chemoresistance mechanism will require drugs that inactivate replication bypass mechanisms. PMID- 29472320 TI - Draft Genome Sequence of a Novel Thermofilum sp.

AB - Assessment of minimal residual disease has emerged as a powerful prognostic factor in acute myeloid leukemia. In this study, we investigated the potential of IDH1/2 mutations as targets for minimal residual disease assessment in acute myeloid leukemia, since these mutations collectively occur in 15-20% of cases of acute myeloid leukemia and now represent druggable targets. We employed droplet digital polymerase chain reaction assays to quantify IDH1R132, IDH2R140, and IDH2R172 mutations on genomic DNA in 322 samples from 103 adult patients with primary IDH1/2 mutant acute myeloid leukemia and enrolled on Acute Leukemia French Association (ALFA) - 0701 or -0702 clinical trials. The median IDH1/2 mutant allele fraction in bone marrow samples was 42.3% (range, 8.2 - 49.9%) at diagnosis of acute myeloid leukemia, and below the detection limit of 0.2% (range, <0.2 - 39.3%) in complete remission after induction therapy. In univariate analysis, the presence of a normal karyotype, a NPM1 mutation, and an IDH1/2 mutant allele fraction <0.2% in bone marrow after induction therapy were statistically significant predictors of longer disease-free survival. In multivariate analysis, these three variables remained significantly predictive of disease-free survival. In 7/103 (7%) patients, IDH1/2 mutations persisted at high levels in complete remission, consistent with the presence of an IDH1/2 mutation in pre-leukemic hematopoietic stem cells. Five out of these seven patients subsequently relapsed or progressed toward myelodysplastic syndrome, suggesting that patients carrying the IDH1/2 mutation in a pre-leukemic clone may be at high risk of hematologic evolution.

AB - Mantle cell lymphoma patients have variable clinical courses, ranging from indolent cases that do not require immediate treatment to aggressive, rapidly progressing diseases. Thus, diagnostic tools capable of stratifying patients according to their risk of relapse and death are needed. This study included 83 samples from the Fondazione Italiana Linfomi MCL-0208 clinical trial. Through gene expression profiling and quantitative real-time PCR we analyzed 46 peripheral blood and 43 formalin-fixed paraffin-embedded lymph node samples. A prediction model to classify patients was developed. By analyzing the transcriptome of 27 peripheral blood samples, two subgroups characterized by a differential expression of genes from the B-cell receptor pathway (B-cell receptorlow and B-cell receptorhigh) were identified. The prediction model based on the quantitative real-time PCR values of six representative genes (AKT3, BCL2, BTK, CD79B, PIK3CD, and SYK), was used to classify the 83 cases (43 B-cell receptorlow and 40 B-cell receptorhigh). The B-cell receptorhigh signature associated with shorter progression-free survival (P=0.0074), selected the mantle cell lymphoma subgroup with the shortest progression-free survival and overall survival (P=0.0014 and P=0.029, respectively) in combination with high (>30%) Ki 67 staining, and was an independent predictor of short progression- free survival along with the Mantle Cell Lymphoma International Prognostic Index-combined score. Moreover, the clinical impact of the 6- gene signature related to the B cell receptor pathway identified a mantle cell lymphoma subset with shorter progression-free survival intervals also in an external independent mantle cell lymphoma cohort homogenously treated with different schedules. In conclusion, this 6-gene signature associates with a poor clinical response in the context of the MCL- 0208 clinical trial. (clinicaltrials.gov identifier: 02354313). PMID- 29472357 TI - Plerixafor enables safe, rapid, efficient mobilization of hematopoietic stem cells in sickle cell disease patients after exchange transfusion. AB - Sickle cell disease is characterized by chronic anemia and vaso-occlusive crises, which eventually lead to multi-organ damage and premature death. Hematopoietic stem cell transplantation is the only curative treatment but it is limited by toxicity and poor availability of HLA-compatible donors. A gene therapy approach based on the autologous transplantation of lentiviral-corrected hematopoietic stem and progenitor cells was shown to be efficacious in one patient. However, alterations of the bone marrow environment and properties of the red blood cells hamper the harvesting and immunoselection of patients' stem cells from bone marrow. The use of Filgrastim to mobilize large numbers of hematopoietic stem and progenitor cells into the circulation has been associated with severe adverse events in sickle cell patients. Thus, broader application of the gene therapy approach requires the development of alternative mobilization methods. We set up a phase I/II clinical trial whose primary objective was to assess the safety of a single injection of Plerixafor in sickle cell patients undergoing red blood cell exchange to decrease the hemoglobin S level to below 30%. The secondary objective was to measure the efficiency of mobilization and isolation of hematopoietic stem and progenitor cells. No adverse events were observed. Large numbers of CD34+ cells were mobilized extremely quickly. Importantly, the mobilized cells contained high numbers of hematopoietic stem cells, expressed high levels of stemness genes, and engrafted very efficiently in immunodeficient mice. Thus, Plerixafor can be safely used to mobilize hematopoietic stem cells in sickle cell patients; this finding opens up new avenues for treatment approaches based on gene addition and genome editing.

AB - Glycoprotein VI, a major platelet activation receptor for collagen and fibrin, is considered a particularly promising, safe antithrombotic target. In this study, we show that human glycoprotein VI signals upon platelet adhesion to fibrinogen. Full spreading of human platelets on fibrinogen was abolished in platelets from glycoprotein VI- deficient patients suggesting that fibrinogen activates platelets through glycoprotein VI. While mouse platelets failed to spread on fibrinogen, human-glycoprotein VI-transgenic mouse platelets showed full spreading and increased Ca2+ signaling through the tyrosine kinase Syk. Direct binding of fibrinogen to human glycoprotein VI was shown by surface plasmon resonance and by increased adhesion to fibrinogen of human glycoprotein VI transfected RBL-2H3 cells relative to mock-transfected cells. Blockade of human glycoprotein VI with the Fab of the monoclonal antibody 9O12 impaired platelet aggregation on preformed platelet aggregates in flowing blood independent of collagen and fibrin exposure. These results demonstrate that human glycoprotein VI binds to immobilized fibrinogen and show that this contributes to platelet spreading and platelet aggregation under flow. PMID- 29472361 TI - A second-generation 15-PGDH inhibitor promotes bone marrow transplant recovery independently of age, transplant dose and granulocyte colony-stimulating factor support. AB - Hematopoietic stem cell transplantation following myeloablative chemotherapy is a curative treatment for many hematopoietic malignancies. However, profound granulocytopenia during the interval between transplantation and marrow recovery exposes recipients to risks of fatal infection, a significant source of transplant-associated morbidity and mortality. We have previously described the discovery of a small molecule, SW033291, that potently inhibits the prostaglandin degrading enzyme 15-PGDH, increases bone marrow prostaglandin E2, and accelerates hematopoietic recovery following murine transplant. Here we describe the efficacy of (+)-SW209415, a second-generation 15-PGDH inhibitor, in an expanded range of models relevant to human transplantation. (+)-SW209415 is 10,000-fold more soluble, providing the potential for intravenous delivery, while maintaining potency in inhibiting 15-PGDH, increasing in vivo prostaglandin E2, and accelerating hematopoietic regeneration following transplantation. In additional models, (+)-SW209415: (i) demonstrated synergy with granulocyte colony stimulating factor, the current standard of care; (ii) maintained efficacy as transplant cell dose was escalated; (iii) maintained efficacy when transplant donors and recipients were aged; and (iv) potentiated homing in xenotransplants using human hematopoietic stem cells. (+)-SW209415 showed no adverse effects, no potentiation of in vivo growth of human myeloma and leukemia xenografts, and, on chronic high-dose administration, no toxicity as assessed by weight, blood counts and serum chemistry. These studies provide independent chemical confirmation of the activity of 15-PGDH inhibitors in potentiating hematopoietic recovery, extend the range of models in which inhibiting 15-PGDH demonstrates activity, allay concerns regarding potential for adverse effects from increasing prostaglandin E2, and thereby, advance 15-PGDH as a therapeutic target for potentiating hematopoietic stem cell transplantation.

PMID- 29472362 TI - Open-label, multicentre, dose-escalating phase II clinical trial on the safety and efficacy of tadekinig alfa (IL-18BP) in adult-onset Still's disease. AB - OBJECTIVES: Adult-onset Still's disease (AOSD) is a rare systemic autoinflammatory disease; its management is largely empirical. This is the first clinical study to determine if interleukin (IL)-18 inhibition, using the recombinant human IL-18 binding protein, tadekinig alfa, is a therapeutic option in AOSD. METHODS: In this phase II, open-label study, patients were >=18 years with active AOSD plus fever or C reactive protein (CRP) levels >=10 mg/L despite treatment with prednisone and/or conventional synthetic disease-modifying antirheumatic drugs (DMARDs). Previous biological DMARD treatment was permitted. Patients received tadekinig alfa 80 mg or 160 mg subcutaneously three times per week for 12 weeks; those receiving 80 mg not achieving early predicted response criteria (reduction of >=50% CRP values from baseline and fever resolution) were up-titrated to 160 mg for a further 12 weeks. The primary endpoint was the occurrence of adverse events (AEs) throughout the study. RESULTS: Ten patients were assigned to receive 80 mg tadekinig alfa and 13 patients to the 160 mg dose. One hundred and fifty-five treatment-emerging AEs were recorded, and 47 were considered related to the study drug. Most AEs were mild and resolved after drug discontinuation. Three serious AEs occurred, one possibly related to treatment (toxic optic neuropathy). At week 3, 5 of 10 patients receiving 80 mg and 6 of 12 patients receiving 160 mg achieved the predefined response criteria. CONCLUSIONS: Our results indicate that tadekinig alfa appears to have a favourable safety profile and is associated with early signs of efficacy in patients with AOSD. TRIAL REGISTRATION NUMBER: NCT02398435. PMID- 29472364 TI - Pseudo-DUBs as allosteric activators and molecular scaffolds of protein complexes. AB - The ubiquitin (Ub) proteasome system and Ub signalling networks are crucial to cell biology and disease development. Deubiquitylases (DUBs) control cell signalling by removing mono-Ub and polyubiquitin chains from substrates. DUBs take part in almost all processes that regulate cellular life and are frequently dysregulated in disease. We have catalogued 99 currently known DUBs in the human genome and sequence conservation analyses of catalytic residues suggest that 11 lack enzyme activity and are classed as pseudo-DUBs. These pseudoenzymes play important biological roles by allosterically activating catalytically competent DUBs as well as other active enzymes. Additionally, pseudoenzymes act as assembly scaffolds of macromolecular complexes. We discuss how pseudo-DUBs have lost their catalytic activity, their diverse mechanisms of action and their potential as therapeutic targets. Many known pseudo-DUBs play crucial roles in cell biology and it is likely that unstudied and overlooked pseudo-DUB genes will have equally important functions. PMID- 29472365 TI - Lysosomal membrane permeabilization as a cell death mechanism in cancer cells. AB - Lysosomes are acidic organelles that contain hydrolytic enzymes that mediate the intracellular degradation of macromolecules. Damage of these organelles often results in lysosomal membrane permeabilization (LMP) and the release into the cytoplasm of the soluble lysosomal contents, which include proteolytic enzymes of the cathepsin family. This, in turn, activates several intracellular cascades that promote a type of regulated cell death, called lysosome-dependent cell death (LDCD). LDCD can be inhibited by pharmacological or genetic blockade of cathepsin activity, or by protecting the lysosomal membrane, thereby stabilizing the organelle. Lysosomal alterations are common in cancer cells and may increase the sensitivity of these cells to agents that promote LMP. In this review, we summarize recent findings supporting the use of LDCD as a means of killing cancer cells. PMID- 29472366 TI - Competitive resource allocation to metabolic pathways contributes to overflow metabolisms and emergent properties in cross-feeding microbial consortia. AB - Resource scarcity is a common stress in nature and has a major impact on microbial physiology. This review highlights microbial acclimations to resource scarcity, focusing on resource investment strategies for chemoheterotrophs from the molecular level to the pathway level. Competitive resource allocation strategies often lead to a phenotype known as overflow metabolism; the resulting overflow byproducts can stabilize cooperative interactions in microbial communities and can lead to cross-feeding consortia. These consortia can exhibit emergent properties such as enhanced resource usage and biomass productivity. The literature distilled here draws parallels between in silico and laboratory studies and ties them together with ecological theories to better understand microbial stress responses and mutualistic consortia functioning. PMID- 29472367 TI - Model-based metabolism design: constraints for kinetic and stoichiometric models. AB - The implementation of model-based designs in metabolic engineering and synthetic biology may fail. One of the reasons for this failure is that only a part of the real-world complexity is included in models. Still, some knowledge can be simplified and taken into account in the form of optimization constraints to improve the feasibility of model-based designs of metabolic pathways in organisms. Some constraints (mass balance, energy balance, and steady-state assumption) serve as a basis for many modelling approaches. There are others (total enzyme activity constraint and homeostatic constraint) proposed decades ago, but which are frequently ignored in design development. Several new approaches of cellular analysis have made possible the application of constraints like cell size, surface, and resource balance. Constraints for kinetic and stoichiometric models are grouped according to their applicability preconditions in (1) general constraints, (2) organism-level constraints, and (3) experiment level constraints. General constraints are universal and are applicable for any system. Organism-level constraints are applicable for biological systems and usually are organism-specific, but these constraints can be applied without information about experimental conditions. To apply experimental-level constraints, peculiarities of the organism and the experimental set-up have to be taken into account to calculate the values of constraints. The limitations of applicability of particular constraints for kinetic and stoichiometric models are addressed. PMID- 29472368 TI - Signaling through plant lectins: modulation of plant immunity and beyond. AB - Lectins constitute an abundant group of proteins that are present throughout the plant kingdom. Only recently, genome-wide screenings have unraveled the multitude of different lectin sequences within one plant species. It appears that plants employ a plurality of lectins, though relatively few lectins have already been studied and functionally characterized. Therefore, it is very likely that the full potential of lectin genes in plants is underrated. This review summarizes the knowledge of plasma membrane-bound lectins in different biological processes (such as recognition of pathogen-derived molecules and symbiosis) and illustrates the significance of soluble intracellular lectins and how they can contribute to plant signaling. Altogether, the family of plant lectins is highly complex with an enormous diversity in biochemical properties and activities. PMID- 29472370 TI - Dual PI3K blockade: PTCL's Achilles heel?

AB - Mast cells play pivotal roles in innate and adaptive immunities but are also culprits in allergy, autoimmunity, and cardiovascular diseases. Mast cells respond to environmental changes by initiating regulated exocytosis/secretion of various biologically active compounds called mediators (e.g. proteases, amines, and cytokines). Many of these mediators are stored in granules/lysosomes and rely on intricate degranulation processes for release. Mast cell stabilizers (e.g. sodium cromoglicate), which prevent such degranulation processes, have therefore been clinically employed to treat asthma and allergic rhinitis. However, it has become increasingly clear that different mast cell diseases often involve multiple mediators that rely on overlapping but distinct mechanisms for release. This review illustrates existing evidence that highlights the diverse exocytic pathways in mast cells. We also discuss strategies to delineate these pathways so as to identify unique molecular components which could serve as new drug targets for more effective and specific treatments against mast cell-related diseases.

AB - PURPOSE: Emerging evidence suggests G3 pancreatic neuroendocrine neoplasms (pNENs) present heterogeneous morphology and biology. The 2017 WHO classification has introduced a new category of well-differentiated pancreatic neuroendocrine tumors (WD-pNETs) G3, compared with poorly differentiated pancreatic neuroendocrine carcinomas (PD-pNECs) G3. We aim to analysis the demographics and outcomes of patients with resectable 2017 WHO G3 pNENs to facilitate the distinction between two entities. METHODS: The multi-institutional retrospective cohort involving 57 surgically treated patients affected by 2017 WHO G3 pNENs were morphologically identified and clinically analyzed. Patients having WD-pNETs G3 and those having PD-pNECs G3 were compared. RESULTS: Thirty patients had WD pNETs and 27 patients had PD-pNECs. The distributions of Ki-67 and mitotic count in patients with PD-pNECs or WD-pNETs showed remarkable disparities. ROC indicated cut-off value of Ki-67 was 45. PD-pNECs were more common in patients with elevated Ki-67 and mitotic count, advanced AJCC TNM stage, vascular invasion, regional lymph-node metastases, elevated NSE and decreased CgA levels compared with WD-pNETs (P < 0.05). The association between 2017 WHO G3 grade and TTR was statistically significant (P < 0.05). Univariate analysis indicated OS rates were associated with morphologic differentiation (WD-pNETs vs PD-pNECs), Ki 67, TNM staging, synchronous distant metastases, initial treatments, vascular invasion, regional lymph nodes metastases, mitotic count and age (P < 0.05). Multivariate analyses illustrated Ki-67, differentiation, TNM staging and vascular invasion were independent predictors (P < 0.05). CONCLUSIONS: PD-pNECs G3 presented malignant biological behavior and dismal outcome compared with WD pNETs G3. These findings challenge 2010 WHO classification and suggest the categorization can be improved by refined tumor grading. PMID- 29472377 TI - TAAR1 induces a disturbed GSK3beta phosphorylation in recurrent miscarriages through the ODC. AB - OBJECTIVES: Thyroid hormones play an important role in the maintenance of pregnancy. Their derivates, endogenous amines, act via binding to the trace amine associated receptor (TAAR1). The aim of our study was to analyse the regulation of TAAR1, serine/threonine kinase (pGSK3beta) and ornithine decarboxylase (ODC) in placentas of healthy pregnancies, spontaneous (SM) and recurrent miscarriages (RM) and to investigate the influence of thyroid hormone derivates on TAAR1 expression in trophoblast model cells in vitro. METHODS: Patients with SM (n = 15) and RM (n = 15) were compared with patients with healthy pregnancies (n = 15) (pregnancy weeks 7-13 each). Immunohistochemistry was applied to analyse placental TAAR1, pGSK3beta and ODC expression. Protein expression of the receptors after stimulation with T3, T1AM and RO5203548 in BeWo trophoblast model cells was determined via Western blot. Double-immunofluorescence was used to determine placental expression of TAAR1 and ODC. RESULTS: Levels of TAAR1, pGSK3beta and ODC were higher in placentas of RM in comparison to healthy controls. Stimulation of BeWo cells with T3, T1AM and RO5203548 significantly increased TAAR1 expression. ODC expression in BeWo cells was upregulated through T3. Via double-immunofluorescence, TAAR1 and ODC-positive EVT could be detected. CONCLUSIONS: Upregulation of placental TAAR1 may indicate an increased decarboxylation of thyroid hormones in miscarriages. Patients with RM may have a lack of T3 through an enhanced transformation of T3 into T1AM induced by the ODC. Future investigations could be carried out to analyse what role a prophylactic T3 substitution plays for patients. PMID- 29472379 TI - DIAGNOSIS OF ENDOCRINE DISEASE: The role of the desmopressin test in the diagnosis and follow-up of Cushing's syndrome. AB - Desmopressin is a vasopressin analogue selective for type 2 vasopressin receptors that mediate renal water retention. In contrast to the native hormone arginine vasopressin, a well-known ACTH secretagogue, desmopressin, exerts minimal or no activity on ACTH excretion. However, in a substantial proportion of patients with ACTH-dependent Cushing's syndrome (CS), desmopressin elicits an ACTH and cortisol response, which contrasts with the minimal responses obtained in healthy subjects. The mechanism underlying this paradoxical response involves upregulation of vasopressin type 3 and/or the aberrant expression of type 2 receptors by neoplastic ACTH-producing cells. This makes desmopressin administration a suitable test enabling the distinction between neoplastic from functional (formerly termed 'pseudo-Cushing syndrome') ACTH-dependent cortisol excess. Several studies have now established an adjunctive role of desmopressin in the initial diagnostic workup of CS. Despite some early data indicating that this test may also have a role in distinguishing between Cushing's disease (CD) and ectopic ACTH secretion, subsequent studies failed to confirm this observation. The ability of the paradoxical response to desmopressin to depict the presence of neoplastic ACTH-secreting cells was also exploited in the follow up of patients with CD undergoing surgery. Loss of the desmopressin response, performed in the early postoperative period, was a good predictor for a favorable long-term outcome. Moreover, during follow-up, reappearance of desmopressin paradoxical response was an early indicator for recurrence. In conclusion, the desmopressin test is a valid tool in both the diagnosis and follow-up of patients with CD and should be more widely applied in the workup of these patients. PMID- 29472378 TI - Hepatic safety of ketoconazole in Cushing's syndrome: results of a Compassionate Use Programme in France. AB - OBJECTIVE: Ketoconazole (KTZ) is one of few available treatments for Cushing's syndrome (CS). Although KTZ has been associated with severe hepatotoxicity, little information is available about hepatic safety in CS. The aim of this study was to document changes in liver function in patients with CS treated with KTZ. DESIGN: An observational prospective French cohort study (Compassionate Use Programme (CUP)). METHODS: Enrolled patients were stratified into a KTZ-naive cohort and a cohort already treated by another formulation of ketoconazole (KTZ switch cohort). Liver function markers (alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase, gamma-glutamyltransferase and bilirubin) were monitored at regular intervals. Patients with ALT > 3 * ULN (upper limit of normal), total bilirubin > 2 * ULN or both ALP > 2 * ULN and ALT > ULN were considered to have liver injury. RESULTS: Overall, 108 patients were analysed (47 KTZ-naive; 61 KTZ-switch). The median KTZ dose was 600 mg/day. Most abnormalities observed were asymptomatic mild increases of liver enzymes. Four patients in the KTZ-naive cohort (8.5%) and two in the KTZ-switch cohort (3.3%) developed liver injury, considered related to KTZ in three cases (all KTZ-naive in the first month of treatment). Five patients had mild liver function abnormalities at baseline and two had proven liver metastases. Two patients recovered on discontinuation of KTZ and the remaining patient died of unrelated causes. CONCLUSIONS: These findings highlight the need for close monitoring of liver enzymes especially during the first six months of treatment. Liver enzyme abnormalities usually occurred within four weeks were asymptomatic and could be reversed on timely discontinuation of KTZ.

AB - Polarization of macrophages to proinflammatory M1 and to antiinflammatory alternatively activated M2 states has physiological implications in the development of experimental hypertension and other pathological conditions. 12/15 Lipoxygenase (12/15-LO) and its enzymatic products 12(S)- and 15(S) hydroxyeicosatetraenoic acid (HETE) are essential in the process since disruption of the gene encoding 12/15-LO renders the mice unsusceptible to hypertension. The objective was to test the hypothesis that M2 macrophages catabolize 12(S)-HETE into products that are incapable of promoting vasoconstriction. Cultured M2 macrophages metabolized externally added [14C]12(S)-HETE into more polar metabolites, while M1 macrophages had little effect on the catabolism. The major metabolites were identified by mass spectrometry as (omega-1)-hydroxylation and beta-oxidation products. The conversion was inhibited by both peroxisomal beta oxidation inhibitor, thioridazine, and cytochrome P450 inhibitors. Quantitative PCR analysis confirmed that several cytochrome P450 enzymes (CYP2E1 and CYP1B1) and peroxisomal beta-oxidation markers were upregulated upon M2 polarization. The identified 12,19-dihydroxy-5,8,10,14-eicosatetraenoic acid and 8-hydroxy-6,10 hexadecadienoic acid metabolites were tested on abdominal aortic rings for biological activity. While 12(S)-HETE enhanced vasoconstrictions to angiotensin II from 15% to 25%, the metabolites did not. These results indicate that M2, but not M1, macrophages degrade 12(S)-HETE into products that no longer enhance the angiotensin II-induced vascular constriction, supporting a possible antihypertensive role of M2 macrophages. PMID- 29472382 TI - Dopamine D2 receptor upregulates leptin and IL-6 in adipocytes. AB - Leptin is a pro-inflammatory cytokine secreted by the adipose tissue. Dopamine D2 receptors (D2Rs) have anti-inflammatory effects in the brain and kidney tissues. Mouse and human adipocytes express D2R; D2R protein was 10-fold greater in adipocytes from human visceral tissue than subcutaneous tissue. However, the function of D2R in adipocytes is not well understood. 3T3-L1 cells were treated with D2-like receptor agonist quinpirole, and immunoblot and quantitative PCR were performed. Quinpirole increased the protein and mRNA expression of leptin and IL-6, but not adiponectin and visfatin (24 h). It also increased the mRNA expression of TNF-alpha , MCP1, and NFkB-p50. An acute increase in the protein expression of leptin and TNF-alpha was also found in the cells treated with quinpirole. The leptin concentration in the culture media was increased by quinpirole-bathing the 3T3-L1 adipocytes. These quinpirole effects on leptin and IL-6 expression were prevented by the D2R antagonist L741,626. Similarly, siRNA mediated silencing of Drd2 decreased the leptin, IL-6, mRNA, and protein expressions. The D2R-mediated increase in leptin expression was prevented by the phosphoinositide 3-kinase inhibitor LY294002. Acute quinpirole treatment in C57Bl/6J mice increased serum leptin concentration and leptin mRNA in visceral adipocyte tissue but not in subcutaneous adipocytes, confirming the stimulatory effect of D2R on leptin in vivo. Our results suggest that the stimulation of D2R increases leptin production and may have a tissue-specific pro-inflammatory effect in adipocytes. PMID- 29472383 TI - Making sense of the clinical spectrum of limb girdle muscular dystrophies. AB - The expansion of the spectrum of limb girdle muscular dystrophies (LGMDs) in recent years means that neurologists need to be familiar with the clinical clues that can help with their diagnosis. The LGMDs comprise a group of genetic myopathies that manifest as chronic progressive weakness of hip and shoulder girdles. Their inheritance is either autosomal dominant (LGMD1) or autosomal recessive (LGMD2). Their prevalence varies in different regions of the world; certain ethnic groups have documented founder mutations and this knowledge can facilitate the diagnosis. The clinical approach to LGMDs uses the age at onset, genetic transmission and clinical patterns of muscular weakness. Helpful clinical features that help to differentiate the various subtypes include: predominant upper girdle weakness, disproportionate respiratory muscle involvement, distal weakness, hip adductor weakness, 'biceps lump' and 'diamond on quadriceps' sign, calf hypertrophy, contractures and cardiac involvement. Almost half of patients with LGMD have such clinical clues. Investigations such as serum creatine kinase, electrophysiology, muscle biopsy and genetic studies can complement the clinical examination. In this review, we discuss diagnostic clinical pointers and comment on the differential diagnosis and relevant investigations, using illustrative case studies. PMID- 29472384 TI - Neuropsychological testing. AB - Neuropsychological testing is a key diagnostic tool for assessing people with dementia and mild cognitive impairment, but can also help in other neurological conditions such as Parkinson's disease, stroke, multiple sclerosis, traumatic brain injury and epilepsy. While cognitive screening tests offer gross information, detailed neuropsychological evaluation can provide data on different cognitive domains (visuospatial function, memory, attention, executive function, language and praxis) as well as neuropsychiatric and behavioural features. We should regard neuropsychological testing as an extension of the neurological examination applied to higher order cortical function, since each cognitive domain has an anatomical substrate. Ideally, neurologists should discuss the indications and results of neuropsychological assessment with a clinical neuropsychologist. This paper summarises the rationale, indications, main features, most common tests and pitfalls in neuropsychological evaluation. PMID- 29472385 TI - Laura Lackner: Passing on the scientific baton.

PMID- 29472380 TI - Spontaneous Coronary Artery Dissection: Current State of the Science: A Scientific Statement From the American Heart Association. AB - Spontaneous coronary artery dissection (SCAD) has emerged as an important cause of acute coronary syndrome, myocardial infarction, and sudden death, particularly among young women and individuals with few conventional atherosclerotic risk factors. Patient-initiated research has spurred increased awareness of SCAD, and improved diagnostic capabilities and findings from large case series have led to changes in approaches to initial and long-term management and increasing evidence that SCAD not only is more common than previously believed but also must be evaluated and treated differently from atherosclerotic myocardial infarction. High rates of recurrent SCAD; its association with female sex, pregnancy, and physical and emotional stress triggers; and concurrent systemic arteriopathies, particularly fibromuscular dysplasia, highlight the differences in clinical characteristics of SCAD compared with atherosclerotic disease. Recent insights into the causes of, clinical course of, treatment options for, outcomes of, and associated conditions of SCAD and the many persistent knowledge gaps are presented. PMID- 29472386 TI - PI(4,5)P2 controls plasma membrane PI4P and PS levels via ORP5/8 recruitment to ER-PM contact sites. AB - Phosphatidylinositol 4,5-bisphosphate (PI(4,5)P2) is a critically important regulatory lipid of the plasma membrane (PM); however, little is known about how cells regulate PM PI(4,5)P2 levels. Here, we show that the phosphatidylinositol 4 phosphate (PI4P)/phosphatidylserine (PS) transfer activity of the endoplasmic reticulum (ER)-resident ORP5 and ORP8 is regulated by both PM PI4P and PI(4,5)P2 Dynamic control of ORP5/8 recruitment to the PM occurs through interactions with the N-terminal Pleckstrin homology domains and adjacent basic residues of ORP5/8 with both PI4P and PI(4,5)P2 Although ORP5 activity requires normal levels of these inositides, ORP8 is called on only when PI(4,5)P2 levels are increased. Regulation of the ORP5/8 attachment to the PM by both phosphoinositides provides a powerful means to determine the relative flux of PI4P toward the ER for PS transport and Sac1-mediated dephosphorylation and PIP 5-kinase-mediated conversion to PI(4,5)P2 Using this rheostat, cells can maintain PI(4,5)P2 levels by adjusting the availability of PI4P in the PM.

PMID- 29472387 TI - Class IIa histone deacetylases link cAMP signaling to the myelin transcriptional program of Schwann cells. AB - Schwann cells respond to cyclic adenosine monophosphate (cAMP) halting proliferation and expressing myelin proteins. Here we show that cAMP signaling induces the nuclear shuttling of the class IIa histone deacetylase (HDAC)-4 in these cells, where it binds to the promoter and blocks the expression of c-Jun, a negative regulator of myelination. To do it, HDAC4 does not interfere with the transcriptional activity of MEF2. Instead, by interacting with NCoR1, it recruits HDAC3 and deacetylates histone 3 in the promoter of c-Jun, blocking gene expression. Importantly, this is enough to up-regulate Krox20 and start Schwann cell differentiation program-inducing myelin gene expression. Using conditional knockout mice, we also show that HDAC4 together with HDAC5 redundantly contribute to activate the myelin transcriptional program and the development of myelin sheath in vivo. We propose a model in which cAMP signaling shuttles class IIa HDACs into the nucleus of Schwann cells to regulate the initial steps of myelination in the peripheral nervous system.

PMID- 29472414 TI - Laminin-521 Protein Therapy for Glomerular Basement Membrane and Podocyte Abnormalities in a Model of Pierson Syndrome. AB - Background Laminin alpha5beta2gamma1 (LM-521) is a major component of the GBM. Mutations in LAMB2 that prevent LM-521 synthesis and/or secretion cause Pierson syndrome, a rare congenital nephrotic syndrome with diffuse mesangial sclerosis and ocular and neurologic defects. Because the GBM is uniquely accessible to plasma, which permeates endothelial cell fenestrae, we hypothesized that intravenous delivery of LM-521 could replace the missing LM-521 in the GBM of Lamb2 mutant mice and restore glomerular permselectivity.Methods We injected human LM-521 (hLM-521), a macromolecule of approximately 800 kD, into the retro orbital sinus of Lamb2-/- pups daily. Deposition of hLM-521 into the GBM was investigated by fluorescence microscopy. We assayed the effects of hLM-521 on glomerular permselectivity by urinalysis and the effects on podocytes by desmin immunostaining and ultrastructural analysis of podocyte architecture.Results Injected hLM-521 rapidly and stably accumulated in the GBM of all glomeruli. Super-resolution imaging showed that hLM-521 accumulated in the correct orientation in the GBM, primarily on the endothelial aspect. Treatment with hLM 521 greatly reduced the expression of the podocyte injury marker desmin and attenuated the foot process effacement observed in untreated pups. Moreover, treatment with hLM-521 delayed the onset of proteinuria but did not prevent nephrotic syndrome, perhaps due to its absence from the podocyte aspect of the GBM.Conclusions These studies show that GBM composition and function can be altered in vivovia vascular delivery of even very large proteins, which may advance therapeutic options for patients with abnormal GBM composition, whether genetic or acquired. PMID- 29472415 TI - Cluster-Randomized Trial of Devices to Prevent Catheter-Related Bloodstream Infection. AB - Central venous catheters (CVCs) contribute disproportionately to bloodstream infection (BSI) and, by extension, to infection-related hospitalization, mortality, and health care costs in patients undergoing dialysis. Recent product advancements may reduce BSIs, but a sufficiently powered comparative effectiveness study is needed to facilitate evidence-based patient care decisions. In a 13-month, prospective, cluster-randomized, open-label trial, we compared BSI rates in facilities using ClearGuard HD antimicrobial barrier caps (ClearGuard group) with those in facilities using Tego hemodialysis connectors plus Curos disinfecting caps (Tego+Curos group). Forty DaVita dialysis facilities in the United States were pair-matched by BSI rate, number of patients using CVCs, and geographic location, and then cluster randomized 1:1. We enrolled all adult patients undergoing dialysis with CVCs at these facilities, except those allergic to heparin or chlorhexidine. Overall, 1671 patients participated in the study, accruing >183,000 CVC-days. The study outcome was positive blood culture (PBC) rate as an indicator of BSI rate. We calculated results at the cluster level and adjusted for the facility cluster effect. During a 3-month run-in period immediately before study interventions, the groups had similar BSI rates (P=0.8). During the 13-month intervention period that immediately followed, the ClearGuard group had a BSI rate significantly lower than that of the Tego+Curos group (0.28 versus 0.75 PBCs per 1000 CVC-days, respectively; P=0.001). No device related adverse events were reported. In conclusion, compared with Tego connectors plus Curos caps, ClearGuard HD antimicrobial barrier caps significantly lowered the rate of catheter-related BSIs in patients undergoing hemodialysis using CVCs, representing an important advancement in hemodialysis patient care. PMID- 29472416 TI - Biomarkers of AKI Progression after Pediatric Cardiac Surgery. AB - Background As children progress to higher stages of AKI, the risk for adverse outcomes dramatically increases. No reliable methods exist to predict AKI progression in hospitalized children. To determine if biomarkers of inflammation and kidney injury can predict AKI progression, we conducted a three-center prospective cohort study of children undergoing cardiopulmonary bypass.Methods On the first day of serum creatinine-defined AKI, we measured urine biomarkers (neutrophil gelatinase-associated lipocalin [NGAL], IL-18, kidney injury molecule 1, liver fatty acid binding protein [L-FABP], albumin, and cystatin C) and plasma biomarkers (IFN, IL-1, IL-2, IL-4, IL-6, IL-8, IL-10, IL-12, IL-13, TNF-alpha, NGAL, and cystatin C). We defined AKI progression as a worsening of AKI stage or persisting stage 3 AKI (>=2 consecutive days).Results In all, 176 of 408 (43%) children developed postoperative AKI. Among the children with AKI, we diagnosed stages 1, 2, and 3 AKI in 145 (82.5%), 25 (14%), and six (3.5%) children, respectively, on the first day of AKI; 28 (7%) children had AKI progression. On the first day of AKI, nine of 17 biomarkers were significantly higher in patients with than without AKI progression. Urine L-FABP (among injury biomarkers) and plasma IL-8 (among inflammatory biomarkers) had the highest discrimination for AKI progression: optimism-corrected area under the curve, 0.70; 95% confidence interval, 0.58 to 0.81 and optimism-corrected area under the curve, 0.80; 95% confidence interval, 0.69 to 0.91, respectively.Conclusions If validated in additional cohorts, plasma IL-8 could be used to improve clinical care and guide enrollment in therapeutic trials of AKI.

A 51-year-old woman presented to a rural hospital with rapid onset bilateral eye swelling, erythema and pain and was started on broad spectrum intravenous antibiotics. Upon admission, she became septic and required fluid resuscitation and transfer to a higher level of care. She received debridement and continued intravenous antibiotics, with step down to oral when clinically stable. Rapid recognition and treatment of her condition resulted in a positive outcome. PMID- 29472419 TI - A womb like a broken heart. AB - Uterine perforation during hysteroscopic operative procedures is a potential complication well known to gynaecologists. Uterine septa are a commonly encountered Mullerian anomaly related to pregnancy loss and infertility. Hysteroscopic resection of septa has shown to improve pregnancy outcome. There are limited case reports of uterine rupture in subsequent pregnancies after hysteroscopic septal resection. Our patient had a hysteroscopic septal resection done a year prior which was complicated by a uterine fundal perforation, left to spontaneously heal after immediate sealing with cautery. The patient conceived spontaneously soon after and underwent an emergency caesarean section for severe pre-eclampsia. Intraoperatively, after removal of the placenta, we discovered a 3 cm symmetrical circular defect at the fundus of the uterus with no myometrium or serosa. The potentially disastrous consequences of this silent uterine rupture were mitigated due to another life-threatening condition which prevented the onset of labour. PMID- 29472417 TI - HDL in CKD-The Devil Is in the Detail. AB - The picture of HDL cholesterol (HDL-C) as the "good" cholesterol has eroded. This is even more surprising because there exists strong evidence that HDL-C is associated with cardiovascular disease (CVD) in the general population as well as in patients with impairment of kidney function and/or progression of CKD. However, drugs that dramatically increase HDL-C have mostly failed to decrease CVD events. Furthermore, genetic studies took the same line, as genetic variants that have a pronounced influence on HDL-C concentrations did not show an association with cardiovascular risk. For many, this was not surprising, given that an HDL particle is highly complex and carries >80 proteins and several hundred lipid species. Simply measuring cholesterol might not reflect the variety of biologic effects of heterogeneous HDL particles. Therefore, functional studies and the involvement of HDL components in the reverse cholesterol transport, including the cholesterol efflux capacity, have become a further focus of study during recent years. As also observed for other aspects, CKD populations behave differently compared with non-CKD populations. Although clear disturbances have been observed for the "functionality" of HDL particles in patients with CKD, this did not necessarily translate into clear-cut associations with outcomes.

He was a known case of inflammatory bowel disease(ulcerative colitis) and was on regular mesalamine therapy. On evaluation, he was having high serum ascites albumin gradient. CT scan of the abdomen revealed features of portal hypertension and non-visualisation of right and middle hepatic veins along with thrombus in inferior vena cava, suggesting a diagnosis of Budd-Chiari syndrome (BCS).

PMID- 29472421 TI - Mycobacterium ChelonaeDeveloping Multidrug Resistance. AB - Mycobacterium chelonae is a rapidly growing mycobacterium which is known to respond well to standard antibiotic treatment regimen. There are no specific guidelines for treatment. Antibiotics are chosen based on the bacterial sensitivity. Here we present a 47-year-old man with hip replacement who developed bright red papular generalised skin lesions and bilateral hip abscess. On workup, it was confirmed that M. chelonae was the causative organism. He was given 8 weeks of antibiotics; however, there was worsening of the hip abscess on interval imaging. The progression was most likely due to M. chelonae developing antibiotic resistance. Physicians should be aware of the rising resistance of this organism, and guide antibiotic therapy based on bacterial sensitivity to yield better outcomes. PMID- 29472422 TI - Prolonged paralysis with atracurium use in a patient with Rubinstein-Taybi syndrome. AB - Rubinstein-Taybi syndrome (RTS) is a rare autosomal dominant disorder that occurs due to a microdeletion of chromosome 16p13. The craniofacial abnormalities in these patients may pose a challenge for anaesthetist performing tracheal intubation. However, there are no known reported cases of drug interaction with non-depolarising muscle relaxant in patients with RTS. This young patient with RTS presented with an unexpected prolonged atracurium effect during the course of anaesthesia. After ruling out other possible causes, we have come to a conclusion that RTS itself could have played a role in the prolonged effect of atracurium. However, further studies will be needed to confirm this hypothesis. In the meantime, care should be used when using muscle relaxants in patients with RTS.

Here, we quantitatively characterized phosphoproteomic changes in an HBx-transgenic mouse model of hepatocellular carcinoma (HCC) using high-resolution mass spectrometry, profiled 22,539 phosphorylation sites on 5431 proteins. Using a strategy to interpret kinase- substrate relations in HCC and to uncover predominant kinases in tumors, our results, revealed elevated kinase activities of Src family kinases (SFKs), PKCs, MAPKs, and ROCK2 in HCC, representatives of which were further validated in cell models and clinical HBV-positive HCC samples. Inhibitor combinations targeting Src and PKCs or ROCK2 both synergized significantly to inhibit cell growth. In addition, we demonstrated that phosphorylation at Src Ser17 directly affects its kinase activity. Our phosphoproteome data facilitated the construction of a detailed molecular landscape in HCC and should serve as a resource for the cancer community. Our strategy is generally applicable to targeted therapeutics, also highlights potential mechanisms of kinase regulation. PMID- 29472432 TI - Predicting the Effect of Fenofibrate on Cardiovascular Risk for Individual Patients With Type 2 Diabetes. AB - OBJECTIVE: In clinical trials, treatment with fenofibrate did not reduce the incidence of major cardiovascular events (MCVE) in patients with type 2 diabetes mellitus (T2DM). However, treatment effects reported by trials comprise patients who respond poorly and patients who respond well to fenofibrate. Our aim was to use statistical modeling to estimate the expected treatment effect of fenofibrate for individual patients with T2DM. RESEARCH DESIGN AND METHODS: To estimate individual risk, the FIELD risk model, with 5-year MCVE as primary outcome, was externally validated in T2DM patients from ACCORD and the SMART observational cohort. Fenofibrate treatment effect was estimated in 17,142 T2DM patients from FIELD, ACCORD, and SMART. Individual treatment effect, expressed as absolute risk reduction (ARR), is the difference between treated and untreated MCVE risk. Results were stratified for patients with and without dyslipidemia (i.e., high triglycerides and low LDL cholesterol). RESULTS: External validation of the FIELD risk model showed good calibration and moderate discrimination in ACCORD (C statistic 0.67 [95% CI 0.65-0.69]) and SMART (C-statistic 0.66 [95% CI 0.63 0.69]). Median 5-year MCVE risk in all three studies combined was 6.7% (interquartile range [IQR] 4.0-11.7) in patients without (N = 13,224) and 9.4% (IQR 5.4-16.1%) in patients with (N = 3,918) dyslipidemia. The median ARR was 2.15% (IQR 1.23-3.68) in patients with dyslipidemia, corresponding with a number needed to treat (NNT) of 47, and 0.22% (IQR 0.13-0.38) in patients without dyslipidemia (NNT 455). CONCLUSIONS: In individual patients with T2DM, there is a wide range of absolute treatment effect of fenofibrate, and overall the fenofibrate treatment effect was larger in patients with dyslipidemia. The method of individualized treatment effect prediction of fenofibrate on MCVE risk reduction in T2DM can be used to guide clinical decision making.

AB - This study evaluated porcine reproductive and respiratory syndrome virus (PRRSV) 2 modified live virus (MLV) vaccine against heterologous single and dual challenge of Korean PRRSV-1 and PRRSV-2. Pigs were administered PRRSV-2 MLV vaccine intramuscularly at 21 days of age and inoculated intranasally with both genotypes at 56 days of age. Vaccination of pigs with PRRSV-2 MLV vaccine resulted in reduction of viral loads of both PRRSV-1 and PRRSV-2 after heterologous single and dual challenge with PRRSV-1 and PRRSV-2. In addition, pigs vaccinated with PRRSV-2 MLV vaccine exhibited higher frequencies of PRRSV-1 and PRRSV-2 specific interferon-gamma secreting cells (IFN-gamma-SC) and showed a significant reduction in lung lesions and PRRSV nucleic acid within the lung lesions after single and dual challenge compared with unvaccinated challenged pigs. Taken together these results demonstrated that vaccination of pigs with PRRSV-2 is efficacious in protecting growing pigs from respiratory disease against heterologous single and dual PRRSV-1 and PRRSV-2 challenge. PMID- 29472440 TI - Recurrences in an isolated quantum many-body system. AB - The complexity of interacting quantum many-body systems leads to exceedingly long recurrence times of the initial quantum state for all but the smallest systems. For large systems, one cannot probe the full quantum state in all its details. Thus, experimentally, recurrences can only be determined on the level of the accessible observables. Realizing a commensurate spectrum of collective excitations in one-dimensional superfluids, we demonstrate recurrences of coherence and long-range order in an interacting quantum many-body system containing thousands of particles. Our findings will enable the study of the coherent dynamics of large quantum systems even after they have reached a transient thermal-like state. PMID- 29472441 TI - Early emergence of cortical interneuron diversity in the mouse embryo. AB - GABAergic interneurons (GABA, gamma-aminobutyric acid) regulate neural-circuit activity in the mammalian cerebral cortex. These cortical interneurons are structurally and functionally diverse. Here, we use single-cell transcriptomics to study the origins of this diversity in the mouse. We identify distinct types of progenitor cells and newborn neurons in the ganglionic eminences, the embryonic proliferative regions that give rise to cortical interneurons. These embryonic precursors show temporally and spatially restricted transcriptional patterns that lead to different classes of interneurons in the adult cerebral cortex. Our findings suggest that shortly after the interneurons become postmitotic, their diversity is already patent in their diverse transcriptional programs, which subsequently guide further differentiation in the developing cortex. PMID- 29472443 TI - Real-time imaging of DNA loop extrusion by condensin. AB - It has been hypothesized that SMC protein complexes such as condensin and cohesin spatially organize chromosomes by extruding DNA into large loops. We directly visualized the formation and processive extension of DNA loops by yeast condensin in real time. Our findings constitute unambiguous evidence for loop extrusion. We observed that a single condensin complex is able to extrude tens of kilobase pairs of DNA at a force-dependent speed of up to 1500 base pairs per second, using the energy of adenosine triphosphate hydrolysis. Condensin-induced loop extrusion was strictly asymmetric, which demonstrates that condensin anchors onto DNA and reels it in from only one side. Active DNA loop extrusion by SMC complexes may provide the universal unifying principle for genome organization. PMID- 29472442 TI - Ancient genomes revisit the ancestry of domestic and Przewalski's horses. AB - The Eneolithic Botai culture of the Central Asian steppes provides the earliest archaeological evidence for horse husbandry, ~5500 years ago, but the exact nature of early horse domestication remains controversial. We generated 42 ancient-horse genomes, including 20 from Botai. Compared to 46 published ancient- and modern-horse genomes, our data indicate that Przewalski's horses are the feral descendants of horses herded at Botai and not truly wild horses. All domestic horses dated from ~4000 years ago to present only show ~2.7% of Botai related ancestry. This indicates that a massive genomic turnover underpins the expansion of the horse stock that gave rise to modern domesticates, which coincides with large-scale human population expansions during the Early Bronze Age.

AB - OBJECTIVES: We examine adolescent receipt of tobacco coupons and subsequent tobacco use. METHODS: Data were from the Population Assessment of Tobacco and Health (PATH) Study (2013-2015). We identified correlates of coupon receipt at Wave 1 (youth sample age 12-17 ; n = 13 651) including demographics, additional vulnerability factors that may place youth at risk of tobacco use and correlates of coupon receipt by channel. We examined associations of Wave 1 coupon receipt with Wave 2 tobacco use using weighted multivariable models. RESULTS: Overall, 7.6% of US youth received tobacco coupons in the 6 months before Wave 1. Coupon recipients were more likely to be women, living outside urban areas, living with a tobacco user, current and former (vs never) tobacco users, having high internalising mental health symptoms and having a favourite tobacco advertisement. Coupons were received primarily through direct mail (56%), product packs (28%) and online (25%). Never tobacco users at Wave 1 who received coupons were more likely to be ever users at Wave 2 (adjusted OR (aOR)=1.42; 95% CI 1.06 to 1.91). Coupon recipients were more likely to use a new tobacco product between waves (aOR=1.67; 95% CI 1.18 to 2.36) and report past 30-day tobacco use at Wave 2 (aOR=1.81; 95% CI 1.31 to 2.49). CONCLUSIONS: One in 13 US youth (7.6%) received coupons. Vulnerable youth had the greatest odds of coupon receipt. Coupon recipients had greater odds of tobacco use among never users, trying a new tobacco product and current use. Coupon bans, limits on youth coupon exposure, stronger age verification, pack inserts or restricting coupon redemption may help reduce tobacco use among adolescents, particularly for those at greatest risk. PMID- 29472445 TI - Impact of tobacco control policies on smoking prevalence and quit ratios in 27 European Union countries from 2006 to 2014. AB - BACKGROUND: Tobacco use is still highly prevalent in Europe, despite the tobacco control efforts made by the governments. The development of tobacco control policies varies substantially across countries. The Tobacco Control Scale (TCS) was introduced to quantify the implementation of tobacco control policies across European countries OBJECTIVE: To assess the midterm association of tobacco control policies on smoking prevalence and quit ratios among 27 European Union (EU) Member States (EU27). METHODS: Ecological study. We used the TCS in EU27 in 2007 and the prevalence of tobacco and quit ratios data from the Eurobarometer survey (2006 (n=27 585) and 2014 (n=26 793)). We analysed the relationship between the TCS scores and smoking prevalence and quit ratios and their relative changes (between 2006 and 2014) by means of scatter plots and multiple linear regression models. RESULTS: In EU27, countries with higher scores in the TCS, which indicates higher tobacco control efforts, have lower prevalence of smokers, higher quit ratios and higher relative decreases in their prevalence rates of smokers over the last decade. The correlation between TCS scores and smoking prevalence (rsp=-0.444; P=0.02) and between the relative changes in smoking prevalence (rsp=-0.415; P=0.03) was negative. A positive correlation was observed between TCS scores and quit ratios (rsp=0.373; P=0.06). The percentage of smoking prevalence explained by all TCS components was 28.9%. CONCLUSION: EU27 should continue implementing comprehensive tobacco control policies as they are key for reducing the prevalence of smoking and an increase tobacco cessation rates in their population. PMID- 29472446 TI - Hematopoiesis by iPSC-derived hematopoietic stem cells of aplastic anemia that escape cytotoxic T-cell attack. AB - Hematopoietic stem cells (HSCs) that lack HLA-class I alleles as a result of copy number neutral loss of heterozygosity of the short arm of chromosome 6 (6pLOH) or HLA allelic mutations often constitute hematopoiesis in patients with acquired aplastic anemia (AA), but the precise mechanisms underlying clonal hematopoiesis induced by these HLA-lacking (HLA-) HSCs remain unknown. To address this issue, we generated induced pluripotent stem cells (iPSCs) from an AA patient who possessed HLA-B4002-lacking (B4002-) leukocytes. Three different iPSC clones (wild-type [WT], 6pLOH+, and B*40:02-mutant) were established from the patient's monocytes. Three-week cultures of the iPSCs in the presence of various growth factors produced hematopoietic cells that make up 50% to 70% of the CD34+ cells of each phenotype. When 106 iPSC-derived CD34+ (iCD34+) cells with the 3 different genotypes were injected into the femoral bone of C57BL/6.Rag2 mice, 2.1% to 7.3% human multilineage CD45+ cells of each HLA phenotype were detected in the bone marrow, spleen, and peripheral blood of the mice at 9 to 12 weeks after the injection, with no significant difference in the human:mouse chimerism ratio among the 3 groups. Stimulation of the patient's CD8+ T cells with the WT iCD34+ cells generated a cytotoxic T lymphocyte (CTL) line capable of killing WT iCD34+ cells but not B4002- iCD34+ cells. These data suggest that B4002- iCD34+ cells show a repopulating ability similar to that of WT iCD34+ cells when autologous T cells are absent and CTL precursors capable of selectively killing WT HSCs are present in the patient's peripheral blood. PMID- 29472447 TI - Dock8 regulates BCR signaling and activation of memory B cells via WASP and CD19. AB - Dock8 deficiency leads to immunodeficiency, and the role of Dock8 in B-cell development and function has been revealed; however, the role of DocK8 on B-cell receptor (BCR) signaling and function of memory B cells remains elusive. In this study, we generated a Dock8 knockout mouse model and collected peripheral blood mononuclear cells from Dock8 patients to study the effect of Dock8 deficiency on the BCR signaling and activation of memory B cells with confocal microscopy and total internal reflection fluorescence microscopy. The activation of key, positive upstream BCR signaling molecules, pCD19 and phosphorylated Brutons tyrosine kinase (pBtk), is reduced. Interestingly, the total protein and activated levels of Wiskott-Aldrich syndrome protein (WASP) are decreased in Dock8-deficient mouse B cells. Our previous research has shown that WASP positively regulates cd19 transcription; furthermore, we found that Dock8 regulates cd19 transcription. What we found in Dock8 patients can be a phenotype copied from Dock8 mice. The early activation of memory B cells from Dock8 patients is disrupted with reduced BCR clustering, B-cell spreading, and signalosome recruitment into the degree of naive B cells, as well as the transition from naive B cells to unswitched memory B cells. Overall, our study provides a novel mechanism for Dock8 regulation of BCR signaling by regulating cd19 transcription, as well as the underlying mechanism of noncompetence of memory B cells in Dock8 patients. PMID- 29472448 TI - Double-stranded DNA break polarity skews repair pathway choice during intrachromosomal and interchromosomal recombination. AB - Activation-induced cytidine deaminase (AID) inflicts DNA damage at Ig genes to initiate class switch recombination (CSR) and chromosomal translocations. However, the DNA lesions formed during these processes retain an element of randomness, and thus knowledge of the relationship between specific DNA lesions and AID-mediated processes remains incomplete. To identify necessary and sufficient DNA lesions in CSR, the Cas9 endonuclease and nickase variants were used to program DNA lesions at a greater degree of predictability than is achievable with conventional induction of CSR. Here we show that Cas9-mediated nicks separated by up to 250 nucleotides on opposite strands can mediate CSR. Staggered double-stranded breaks (DSBs) result in more end resection and junctional microhomology than blunt DSBs. Moreover, Myc-Igh chromosomal translocations, which are carried out primarily by alternative end joining (A EJ), were preferentially induced by 5' DSBs. These data indicate that DSBs with 5' overhangs skew intrachromosomal and interchromosomal end-joining toward A-EJ. In addition to lending potential insight to AID-mediated phenomena, this work has broader carryover implications in DNA repair and lymphomagenesis. PMID- 29472450 TI - Race to the native state. PMID- 29472449 TI - Nrf2 activation attenuates genetic endoplasmic reticulum stress induced by a mutation in the phosphomannomutase 2 gene in zebrafish. AB - Nrf2 plays critical roles in animals' defense against electrophiles and oxidative stress by orchestrating the induction of cytoprotective genes. We previously isolated the zebrafish mutant it768, which displays up-regulated expression of Nrf2 target genes in an uninduced state. In this paper, we determine that the gene responsible for it768 was the zebrafish homolog of phosphomannomutase 2 (Pmm2), which is a key enzyme in the initial steps of N-glycosylation, and its mutation in humans leads to PMM2-CDG (congenital disorders of glycosylation), the most frequent type of CDG. The pmm2it768 larvae exhibited mild defects in N glycosylation, indicating that the pmm2it768 mutation is a hypomorph, as in human PMM2-CDG patients. A gene expression analysis showed that pmm2it768 larvae display up-regulation of endoplasmic reticulum (ER) stress, suggesting that the activation of Nrf2 was induced by the ER stress. Indeed, the treatment with the ER stress-inducing compounds up-regulated the gstp1 expression in an Nrf2 dependent manner. Furthermore, the up-regulation of gstp1 by the pmm2 inactivation was diminished by knocking down or out double-stranded RNA-activated protein kinase (PKR)-like ER kinase (PERK), one of the main ER stress sensors, suggesting that Nrf2 was activated in response to the ER stress via the PERK pathway. ER stress-induced activation of Nrf2 was reported previously, but the results have been controversial. Our present study clearly demonstrated that ER stress can indeed activate Nrf2 and this regulation is evolutionarily conserved among vertebrates. Moreover, ER stress induced in pmm2it768 mutants was ameliorated by the treatment of the Nrf2-activator sulforaphane, indicating that Nrf2 plays significant roles in the reduction of ER stress. PMID- 29472451 TI - Genetic manipulation of structural color in bacterial colonies. AB - Naturally occurring photonic structures are responsible for the bright and vivid coloration in a large variety of living organisms. Despite efforts to understand their biological functions, development, and complex optical response, little is known of the underlying genes involved in the development of these nanostructures in any domain of life. Here, we used Flavobacterium colonies as a model system to demonstrate that genes responsible for gliding motility, cell shape, the stringent response, and tRNA modification contribute to the optical appearance of the colony. By structural and optical analysis, we obtained a detailed correlation of how genetic modifications alter structural color in bacterial colonies. Understanding of genotype and phenotype relations in this system opens the way to genetic engineering of on-demand living optical materials, for use as paints and living sensors. PMID- 29472452 TI - Group size in social-ecological systems. AB - Cooperation becomes more difficult as a group becomes larger, but it is unclear where it will break down. Here, we study group size within well-functioning social-ecological systems. We consider centuries-old evidence from hundreds of communities in the Alps that harvested common property resources. Results show that the average group size remained remarkably stable over about six centuries, in contrast to a general increase in the regional population. The population more than doubled, but although single groups experienced fluctuations over time, the average group size remained stable. Ecological factors, such as managing forest instead of pasture land, played a minor role in determining group size. The evidence instead indicates that factors related to social interactions had a significant role in determining group size. We discuss possible interpretations of the findings based on constraints in individual cognition and obstacles in collective decision making. PMID- 29472453 TI - Comment on "The whole-soil carbon flux in response to warming". AB - In a compelling study, Hicks Pries et al (Reports, 31 March 2017, p. 1420) showed that 4 degrees C warming enhanced soil CO2 production in the 1-meter soil profile, with all soil depths displaying similar temperature sensitivity (Q10). We argue that some caveats can be identified in their experimental approach and analysis, and that these critically undermine their conclusions and hence their claim that the strength of feedback between the whole-soil carbon and climate has been underestimated in terrestrial models. PMID- 29472454 TI - Response to Comment on "The whole-soil carbon flux in response to warming". AB - Temperature records and model predictions demonstrate that deep soils warm at the same rate as surface soils, contrary to Xiao et al's assertions. In response to Xiao et al's critique of our Q10 analysis, we present the results with all data points included, which show Q10 values of >2 throughout the soil profile, indicating that all soil depths responded to warming.

AB - Mitochondrial apoptosis is mediated by BAK and BAX, two proteins that induce mitochondrial outer membrane permeabilization, leading to cytochrome c release and activation of apoptotic caspases. In the absence of active caspases, mitochondrial DNA (mtDNA) triggers the innate immune cGAS/STING pathway, causing dying cells to secrete type I interferon. How cGAS gains access to mtDNA remains unclear. We used live-cell lattice light-sheet microscopy to examine the mitochondrial network in mouse embryonic fibroblasts. We found that after BAK/BAX activation and cytochrome c loss, the mitochondrial network broke down and large BAK/BAX pores appeared in the outer membrane. These BAK/BAX macropores allowed the inner mitochondrial membrane to herniate into the cytosol, carrying with it mitochondrial matrix components, including the mitochondrial genome. Apoptotic caspases did not prevent herniation but dismantled the dying cell to suppress mtDNA-induced innate immune signaling. PMID- 29472458 TI - Europe's first artists were Neandertals.

AB - Laser-based range measurement systems are important in many application areas, including autonomous vehicles, robotics, manufacturing, formation flying of satellites, and basic science. Coherent laser ranging systems using dual frequency combs provide an unprecedented combination of long range, high precision, and fast update rate. We report dual-comb distance measurement using chip-based soliton microcombs. A single pump laser was used to generate dual frequency combs within a single microresonator as counterpropagating solitons. We demonstrated time-of-flight measurement with 200-nanometer precision at an averaging time of 500 milliseconds within a range ambiguity of 16 millimeters. Measurements at distances up to 25 meters with much lower precision were also performed. Our chip-based source is an important step toward miniature dual-comb laser ranging systems that are suitable for photonic integration. PMID- 29472478 TI - Infrared hyperbolic metasurface based on nanostructured van der Waals materials. AB - Metasurfaces with strongly anisotropic optical properties can support deep subwavelength-scale confined electromagnetic waves (polaritons), which promise opportunities for controlling light in photonic and optoelectronic applications. We developed a mid-infrared hyperbolic metasurface by nanostructuring a thin layer of hexagonal boron nitride that supports deep subwavelength-scale phonon polaritons that propagate with in-plane hyperbolic dispersion. By applying an infrared nanoimaging technique, we visualize the concave (anomalous) wavefronts of a diverging polariton beam, which represent a landmark feature of hyperbolic polaritons. The results illustrate how near-field microscopy can be applied to reveal the exotic wavefronts of polaritons in anisotropic materials and demonstrate that nanostructured van der Waals materials can form a highly variable and compact platform for hyperbolic infrared metasurface devices and circuits. PMID- 29472477 TI - Ultrafast optical ranging using microresonator soliton frequency combs. AB - Light detection and ranging is widely used in science and industry. Over the past decade, optical frequency combs were shown to offer advantages in optical ranging, enabling fast distance acquisition with high accuracy. Driven by emerging high-volume applications such as industrial sensing, drone navigation, or autonomous driving, there is now a growing demand for compact ranging systems. Here, we show that soliton Kerr comb generation in integrated silicon nitride microresonators provides a route to high-performance chip-scale ranging systems. We demonstrate dual-comb distance measurements with Allan deviations down to 12 nanometers at averaging times of 13 microseconds along with ultrafast ranging at acquisition rates of 100 megahertz, allowing for in-flight sampling of gun projectiles moving at 150 meters per second. Combining integrated soliton-comb ranging systems with chip-scale nanophotonic phased arrays could enable compact ultrafast ranging systems for emerging mass applications. PMID- 29472479 TI - Nitrogen fixation and reduction at boron. AB - Currently, the only compounds known to support fixation and functionalization of dinitrogen (N2) under nonmatrix conditions are based on metals. Here we present the observation of N2 binding and reduction by a nonmetal, specifically a dicoordinate borylene. Depending on the reaction conditions under which potassium graphite is introduced as a reductant, N2 binding to two borylene units results in either neutral (B2N2) or dianionic ([B2N2]2-) products that can be interconverted by respective exposure to further reductant or to air. The 15N isotopologues of the neutral and dianionic molecules were prepared with 15N labeled dinitrogen, allowing observation of the nitrogen nuclei by 15N nuclear magnetic resonance spectroscopy. Protonation of the dianionic compound with distilled water furnishes a diradical product with a central hydrazido B2N2H2 unit. All three products were characterized spectroscopically and crystallographically. PMID- 29472480 TI - Breakup of last glacial deep stratification in the South Pacific. AB - Stratification of the deep Southern Ocean during the Last Glacial Maximum is thought to have facilitated carbon storage and subsequent release during the deglaciation as stratification broke down, contributing to atmospheric CO2 rise. Here, we present neodymium isotope evidence from deep to abyssal waters in the South Pacific that confirms stratification of the deepwater column during the Last Glacial Maximum. The results indicate a glacial northward expansion of Ross Sea Bottom Water and a Southern Hemisphere climate trigger for the deglacial breakup of deep stratification. It highlights the important role of abyssal waters in sustaining a deep glacial carbon reservoir and Southern Hemisphere climate change as a prerequisite for the destabilization of the water column and hence the deglacial release of sequestered CO2 through upwelling. PMID- 29472481 TI - Tracking the global footprint of fisheries. AB - Although fishing is one of the most widespread activities by which humans harvest natural resources, its global footprint is poorly understood and has never been directly quantified. We processed 22 billion automatic identification system messages and tracked >70,000 industrial fishing vessels from 2012 to 2016, creating a global dynamic footprint of fishing effort with spatial and temporal resolution two to three orders of magnitude higher than for previous data sets. Our data show that industrial fishing occurs in >55% of ocean area and has a spatial extent more than four times that of agriculture. We find that global patterns of fishing have surprisingly low sensitivity to short-term economic and environmental variation and a strong response to cultural and political events such as holidays and closures. PMID- 29472482 TI - Coral reefs will transition to net dissolving before end of century. AB - Ocean acidification refers to the lowering of the ocean's pH due to the uptake of anthropogenic CO2 from the atmosphere. Coral reef calcification is expected to decrease as the oceans become more acidic. Dissolving calcium carbonate (CaCO3) sands could greatly exacerbate reef loss associated with reduced calcification but is presently poorly constrained. Here we show that CaCO3 dissolution in reef sediments across five globally distributed sites is negatively correlated with the aragonite saturation state (Omegaar) of overlying seawater and that CaCO3 sediment dissolution is 10-fold more sensitive to ocean acidification than coral calcification. Consequently, reef sediments globally will transition from net precipitation to net dissolution when seawater Omegaar reaches 2.92 +/- 0.16 (expected circa 2050 CE). Notably, some reefs are already experiencing net sediment dissolution. PMID- 29472483 TI - U-Th dating of carbonate crusts reveals Neandertal origin of Iberian cave art. AB - The extent and nature of symbolic behavior among Neandertals are obscure. Although evidence for Neandertal body ornamentation has been proposed, all cave painting has been attributed to modern humans. Here we present dating results for three sites in Spain that show that cave art emerged in Iberia substantially earlier than previously thought. Uranium-thorium (U-Th) dates on carbonate crusts overlying paintings provide minimum ages for a red linear motif in La Pasiega (Cantabria), a hand stencil in Maltravieso (Extremadura), and red-painted speleothems in Ardales (Andalucia). Collectively, these results show that cave art in Iberia is older than 64.8 thousand years (ka). This cave art is the earliest dated so far and predates, by at least 20 ka, the arrival of modern humans in Europe, which implies Neandertal authorship. PMID- 29472485 TI - Structural principles that enable oligomeric small heat-shock protein paralogs to evolve distinct functions. AB - Oligomeric proteins assemble with exceptional selectivity, even in the presence of closely related proteins, to perform their cellular roles. We show that most proteins related by gene duplication of an oligomeric ancestor have evolved to avoid hetero-oligomerization and that this correlates with their acquisition of distinct functions. We report how coassembly is avoided by two oligomeric small heat-shock protein paralogs. A hierarchy of assembly, involving intermediates that are populated only fleetingly at equilibrium, ensures selective oligomerization. Conformational flexibility at noninterfacial regions in the monomers prevents coassembly, allowing interfaces to remain largely conserved. Homomeric oligomers must overcome the entropic benefit of coassembly and, accordingly, homomeric paralogs comprise fewer subunits than homomers that have no paralogs.

AB - Patient-derived organoids (PDOs) have recently emerged as robust preclinical models; however, their potential to predict clinical outcomes in patients has remained unclear. We report on a living biobank of PDOs from metastatic, heavily pretreated colorectal and gastroesophageal cancer patients recruited in phase 1/2 clinical trials. Phenotypic and genotypic profiling of PDOs showed a high degree of similarity to the original patient tumors. Molecular profiling of tumor organoids was matched to drug-screening results, suggesting that PDOs could complement existing approaches in defining cancer vulnerabilities and improving treatment responses. We compared responses to anticancer agents ex vivo in organoids and PDO-based orthotopic mouse tumor xenograft models with the responses of the patients in clinical trials. Our data suggest that PDOs can recapitulate patient responses in the clinic and could be implemented in personalized medicine programs. PMID- 29472486 TI - Single-cell bioluminescence imaging of deep tissue in freely moving animals. AB - Bioluminescence is a natural light source based on luciferase catalysis of its substrate luciferin. We performed directed evolution on firefly luciferase using a red-shifted and highly deliverable luciferin analog to establish AkaBLI, an all engineered bioluminescence in vivo imaging system. AkaBLI produced emissions in vivo that were brighter by a factor of 100 to 1000 than conventional systems, allowing noninvasive visualization of single cells deep inside freely moving animals. Single tumorigenic cells trapped in the mouse lung vasculature could be visualized. In the mouse brain, genetic labeling with neural activity sensors allowed tracking of small clusters of hippocampal neurons activated by novel environments. In a marmoset, we recorded video-rate bioluminescence from neurons in the striatum, a deep brain area, for more than 1 year. AkaBLI is therefore a bioengineered light source to spur unprecedented scientific, medical, and industrial applications. PMID- 29472489 TI - Responses to mechanically and visually cued water waves in the nervous system of the medicinal leech. AB - Sensitivity to water waves is a key modality by which aquatic predators can detect and localize their prey. For one such predator - the medicinal leech, Hirudo verbana - behavioral responses to visual and mechanical cues from water waves are well documented. Here, we quantitatively characterized the response patterns of a multisensory interneuron, the S cell, to mechanically and visually cued water waves. As a function of frequency, the response profile of the S cell replicated key features of the behavioral prey localization profile in both visual and mechanical modalities. In terms of overall firing rate, the S cell response was not direction selective, and although the direction of spike propagation within the S cell system did follow the direction of wave propagation under certain circumstances, it is unlikely that downstream neuronal targets can use this information. Accordingly, we propose a role for the S cell in the detection of waves but not in the localization of their source. We demonstrated that neither the head brain nor the tail brain are required for the S cell to respond to visually cued water waves. PMID- 29472490 TI - RNA thermosensors: how might animals exploit their regulatory potential? AB - The secondary and tertiary orders of RNA structure are crucial for a suite of RNA related functions, including regulation of translation, gene expression and RNA turnover. The temperature sensitivity of RNA secondary and tertiary structures is exploited by bacteria to fabricate RNA thermosensing systems that allow a rapid adaptive response to temperature change. RNA thermometers (RNATs) present in non coding regions of certain mRNAs of pathogenic bacteria enable rapid upregulation of translation of virulence proteins when the temperature of the bacterium rises after entering a mammalian host. Rapid upregulation of translation of bacterial heat-shock proteins likewise is governed in part by RNATs. Turnover of mRNA may be regulated by temperature-sensitive RNA structures. Whereas the roles of temperature-sensitive RNA structures similar to RNATs in Eukarya and Archaea are largely unknown, there would appear to be a potential for all taxa to adaptively regulate their thermal physiology through exploitation of RNA-based thermosensory responses akin to those of bacteria. In animals, these responses might include regulation of translation of stress-induced proteins, alternative splicing of messenger RNA precursors, differential expression of allelic proteins, modulation of activities of small non-coding RNAs, regulation of mRNA turnover and control of RNA editing. New methods for predicting, detecting and experimentally modifying RNA secondary structure offer promising windows into these fascinating aspects of RNA biochemistry. Elucidating whether animals too have exploited the types of RNA thermosensing tools that are used so effectively by bacteria seems likely to provide exciting new insights into the mechanisms of evolutionary adaptation and acclimatization to temperature. PMID- 29472491 TI - Child Health Outcomes After Presumptive Infection Treatment in Pregnant Women: A Randomized Trial. AB - BACKGROUND AND OBJECTIVES: We showed earlier that presumptive infection treatment in pregnancy reduced the prevalence of neonatal stunting in a rural low-income setting. In this article, we assess how these gains were sustained and reflected in childhood growth, development, and mortality. METHODS: We enrolled 1320 pregnant Malawian women in a randomized trial and treated them for malaria and other infections with either 2 doses of sulfadoxine-pyrimethamine (SP) (control), monthly SP, or monthly sulfadoxine-pyrimethamine and 2 doses of azithromycin (AZI SP). Child height or length and mortality were recorded at 1, 6, 12, 24, 36, 48, and 60 months and development at 60 months by using Griffith's Mental Development Scales. RESULTS: Throughout follow-up, the mean child length was 0.4 to 0.7 cm higher (P < .05 at 1-12 months), the prevalence of stunting was 6 to 11 percentage points lower (P < .05 at 12-36 months), and the 5-year cumulative incidence of stunting was 13 percentage points lower (hazard ratio: 0.70, 95% confidence interval [CI]: 0.60 to 0.83, P < .001) in the AZI-SP group than in the control group. The mean developmental score was 3.8 points higher in the AZI-SP group than in the control group (95% CI: 1.1 to 6.4, P = .005). Total mortality during pregnancy and childhood was 15.3%, 15.1%, and 13.1% (P = .60) in the control, monthly SP, and AZI-SP groups, respectively. Postneonatal mortality (secondary outcome) was 5.5%, 3.3%, and 1.9%, respectively (risk ratio of AZI-SP versus control: 0.34, 95% CI: 0.15 to 0.76, P = .008). CONCLUSIONS: Provision of AZI-SP rather than 2 doses of SP during pregnancy reduced the incidence of stunting in childhood. AZI-SP during pregnancy also had a positive effect on child development and may have reduced postneonatal mortality. PMID- 29472492 TI - Angiomatoid Fibrous Histiocytoma With Paraneoplastic Platelet Storage Pool Deficiency. AB - Angiomatoid fibrous histiocytoma is a rare soft tissue tumor usually discovered in young individuals. This tumor is often mistaken for a hematoma and typically misdiagnosed. It is commonly found in the extremities and may be associated with a site of recent or previous trauma. Characteristic histology includes nodules of histiocytoid spindle cells with pseudoangiomatoid spaces, fibrous pseudocapsules, and lymphoid cuffing. We describe the case of an 8-year-old girl who presented after incision and drainage of a superficial thigh lesion and experienced subsequent chronic bleeding of her wound. Her initial presentation was concerning for an underlying bleeding disorder, and laboratory analysis uncovered a paraneoplastic platelet function disorder that resolved with therapy of the primary tumor. PMID- 29472493 TI - Variation in Anthropometric Status and Growth Failure in Low- and Middle-Income Countries. AB - BACKGROUND: Addressing anthropometric failure in low- and middle-income countries can have 2 targets of inference: addressing differences between individuals within populations (Wpop) or differences between populations (Bpop). We present a multilevel framework to apply both targets of inference simultaneously and quantify the extent to which variation in anthropometric status and growth failure is reflective of undernourished children or undernourished populations. METHODS: Cross-sectional data originated from the Demographic and Health Surveys program, covering children under age 5 from 57 countries surveyed between 2001 and 2015. RESULTS: A majority of variation in child anthropometric status and growth failure was attributable to Wpop-associated differences, accounting for 89%, 83%, and 85% of the variability in z scores for height for age, weight for age, and weight for height. Bpop-associated differences (communities, regions, and countries combined) were associated with 11%, 17%, and 15% of the variation in height-for-age z score, weight-for-age z score, and weight-for-height z score. Prevalence of anthropometric failure was closely correlated with mean levels of height and weight. Approximately 1% of Wpop variability, compared with 30% to 50% of the Bpop variability, was explained by mean values of maternal correlates of anthropometric status and failure. Although there is greater explanatory power Bpop, this varied because of modifiability of what constitutes population. CONCLUSIONS: Our results suggest that universal strategies to prevent future anthropometric failure in populations combined with targeted strategies to address both the impending and existing burden among children are needed.

METHODS: In this study, we used linked data from the Pediatric Health Information System database and the US Census Bureau to examine associations between median annual household income by zip code and mortality, length of stay, inpatient standardized costs, and costs per day, over and above the effects of race and payer, first for children undergoing cardiac surgery (2005-2015) and then for all pediatric discharges (2012-2015). Median community level income was examined as continuous and categorical (by quartile) predictors. Hierarchical logistic and censored linear regression models were constructed. To these models, patient and surgical characteristics, year, race, payer, state, urban or rural designation, and center fixed effects were added. RESULTS: We identified 101 013 cardiac surgical (and 857 833 total) hospitalizations from 46 institutions. Children from the lowest-income neighborhoods who were undergoing cardiac surgery had 1.18 times the odds of mortality (95% confidence interval [CI]: 1.03 to 1.35), 7% longer lengths of stay (CI: 1% to 14%), and 7% higher standardized costs (CI: 1% to 14%) than children from the highest-income neighborhoods. Results for all children were similar, both with and without any major chronic conditions. The effects of neighborhood were only partially explained by differences in race, payer, or the centers at which patients received care. There were no differences in costs per day. CONCLUSIONS: Children from lower-income neighborhoods are at increased risk of mortality and use more resource intensive care than children from higher-income communities, even after accounting for disparities between races, payers, and centers.

AB - There is little known about the impact of nonalcoholic fatty liver disease (NAFLD) on drug metabolism and transport. We examined the pharmacokinetics of oral apixaban (2.5 mg) and rosuvastatin (5 mg) when administered simultaneously in subjects with magnetic resonance imaging-confirmed NAFLD (N = 22) and healthy control subjects (N = 12). The area under the concentration-time curve to the last sampling time (AUC0-12) values for apixaban were not different between control and NAFLD subjects (671 and 545 ng/ml * hour, respectively; P = 0.15). Similarly, the AUC0-12 values for rosuvastatin did not differ between the control and NAFLD groups (25.4 and 20.1 ng/ml * hour, respectively; P = 0.28). Furthermore, hepatic fibrosis in NAFLD subjects was not associated with differences in apixaban or rosuvastatin pharmacokinetics. Decreased systemic exposures for both apixaban and rosuvastatin were associated with increased body weight (P < 0.001 and P < 0.05, respectively). In multivariable linear regression analyses, only participant weight but not NAFLD, age, or SLCO1B1/ABCG2/CYP3A5 genotypes, was associated with apixaban and rosuvastatin AUC0-12 (P < 0.001 and P = 0.06, respectively). NAFLD does not appear to affect the pharmacokinetics of apixaban or rosuvastatin. PMID- 29472496 TI - IL-7-dependent maintenance of ILC3s is required for normal entry of lymphocytes into lymph nodes. AB - IL-7 is essential for the development and homeostasis of T and B lymphocytes and is critical for neonatal lymph node organogenesis because Il7-/- mice lack normal lymph nodes. Whether IL-7 is a continued requirement for normal lymph node structure and function is unknown. To address this, we ablated IL-7 function in normal adult hosts. Either inducible Il7 gene deletion or IL-7R blockade in adults resulted in a rapid loss of lymph node cellularity and a corresponding defect in lymphocyte entry into lymph nodes. Although stromal and dendritic cell components of lymph nodes were present in normal numbers and representation, innate lymphoid cell (ILC) subpopulations were substantially decreased after IL-7 ablation. Testing lymphocyte homing in bone marrow chimeras reconstituted with Rorc-/- bone marrow confirmed that ILC3s in lymph nodes are required for normal lymphocyte homing. Collectively, our data suggest that maintenance of intact lymph nodes relies on IL-7-dependent maintenance of ILC3 cells. PMID- 29472499 TI - Brucella replicates in the ER. PMID- 29472498 TI - The bone marrow microenvironment in health and disease at a glance. AB - The bone marrow microenvironment (BMM) is the 'domicile' of hematopoietic stem cells, as well as of malignant processes that can develop there. Multiple and complex interactions with the BMM influence hematopoietic stem cell (HSC) physiology, but also the pathophysiology of hematological malignancies. Reciprocally, hematological malignancies alter the BMM, in order to render it more hospitable for malignant progression. In this Cell Science at a Glance article and accompanying poster, we highlight concepts of the normal and malignant hematopoietic stem cell niches. We present the intricacies of the BMM in malignancy and provide approaches for targeting the interactions between malignant cells and their BMM. This is done in an effort to augment existing treatment strategies in the future. PMID- 29472500 TI - The fly eye as a model system for centriole organization.

PMID- 29472497 TI - ADAM17 is required for EGF-R-induced intestinal tumors via IL-6 trans-signaling. AB - Colorectal cancer is treated with antibodies blocking epidermal growth factor receptor (EGF-R), but therapeutic success is limited. EGF-R is stimulated by soluble ligands, which are derived from transmembrane precursors by ADAM17 mediated proteolytic cleavage. In mouse intestinal cancer models in the absence of ADAM17, tumorigenesis was almost completely inhibited, and the few remaining tumors were of low-grade dysplasia. RNA sequencing analysis demonstrated down regulation of STAT3 and Wnt pathway components. Because EGF-R on myeloid cells, but not on intestinal epithelial cells, is required for intestinal cancer and because IL-6 is induced via EGF-R stimulation, we analyzed the role of IL-6 signaling. Tumor formation was equally impaired in IL-6-/- mice and sgp130Fc transgenic mice, in which only trans-signaling via soluble IL-6R is abrogated. ADAM17 is needed for EGF-R-mediated induction of IL-6 synthesis, which via IL-6 trans-signaling induces beta-catenin-dependent tumorigenesis. Our data reveal the possibility of a novel strategy for treatment of colorectal cancer that could circumvent intrinsic and acquired resistance to EGF-R blockade.

PMID- 29472508 TI - False prolongation of International Normalized Ratio associated with daptomycin. AB - PURPOSE: Persistent elevation of prothrombin time (PT) and International Normalized Ratio (INR) values in a patient receiving daptomycin is reported. SUMMARY: A morbidly obese 51-year-old man was hospitalized for evaluation for surgical intervention for gallstone pancreatitis and biliary obstruction. Previously prescribed warfarin therapy was withheld due to suspected coagulopathy and an elevated INR (5.1), and warfarin reversal was initiated. After undergoing partial cholecystectomy on hospital day 6, the patient developed sepsis and was treated with i.v. meropenem and daptomycin for vancomycin-resistant Enterococcus infection. Warfarin therapy, which had been resumed after cholecystectomy, was again discontinued on hospital day 12. On the eighth day of daptomycin therapy, the INR remained elevated (2.6) even though the patient had no warfarin exposure for 9 days. On hospital day 21, thromboelastography (TEG) indicated normal whole blood coagulation. Other anticoagulation markers normalized, but the INR remained elevated until daptomycin was discontinued. Daptomycin has been shown to falsely prolong the INR when specific laboratory reagents are used for PT and INR testing, but the specific reagent used in this case has not been previously implicated. CONCLUSION: Daptomycin therapy appeared to cause a false and substantial INR elevation in a patient who had been receiving warfarin. Results of TEG suggested that the INR elevation was an artifact of a drug-laboratory interaction and did not represent an anticoagulated state. The patient's INR normalized after linezolid was substituted for daptomycin. PMID- 29472509 TI - Association between continuous peripheral i.v. infusion of 3% sodium chloride injection and phlebitis in adults. AB - PURPOSE: One institution's experience with use of peripheral i.v. (PIV) catheters for prolonged infusions of 3% sodium chloride injection at rates up to 100 mL/hr is described. METHODS: A prospective, observational, 13-month quality assurance project was conducted at an academic medical center to evaluate frequencies of patient and catheter phlebitis among adult inpatients who received both an infusion of 3% sodium chloride injection for a period of >=4 hours through a dedicated PIV catheter and infusions of routine-care solutions (RCSs) through separate PIV catheters during the same hospital stay. RESULTS: Sixty patients received PIV infusions through a total of 291 catheters during the study period. The majority of patients (78%) received infusions of 3% sodium chloride injection for intracranial hypertension, with 30% receiving such infusions in the intensive care unit. Phlebitis occurred in 28 patients (47%) during infusions of 3% sodium chloride and 26 patients (43%) during RCS infusions (p = 0.19). Catheter phlebitis occurred in 73 catheters (25%), with no significant difference in the frequencies of catheter phlebitis with infusion of 3% sodium chloride versus RCSs (30% [32 of 106 catheters]) versus 22% [41 of 185 catheters]), p = 0.16). CONCLUSION: Patient and catheter phlebitis rates were not significantly different with infusions of 3% sodium chloride injection versus RCSs, suggesting that an osmolarity cutoff value of 900 mOsm/L for peripheral infusions of hypertonic saline solutions may not be warranted. PMID- 29472510 TI - Rates of depressive symptoms among pharmacy residents. AB - PURPOSE: Results of a survey-based study assessing rates of depression and depressive symptoms among pharmacy residents are reported. METHODS: In a time series study conducted during the 2015-16 residency year, pharmacy residents nationwide were invited to participate in a series of online surveys (administered in September and December 2015 and March 2016). Survey participants reported demographic data and provided information on residency characteristics and perceived family and program support; the survey incorporated the 9-item depression screening component of the Patient Health Questionnaire (PHQ-9). Descriptive statistics were used to estimate rates of depression and depressive symptoms. RESULTS: There were 633, 542, and 749 respondents to the September, December, and March surveys, respectively, for an overall response rate of 20.5%. The mean age of respondents was 26.9 years. Among respondents to the March survey, 39.9% (95% confidence interval, 36.2-43.2%) reported moderate-to-severe depressive symptoms. The rate of severe depressive symptoms (as measured by PHQ-9 scores) increased from 3.2% in the September survey to 7.8% in the March survey (p < 0.05); rates of self-reported low depressive symptoms decreased over the same time period (p < 0.05). By comparison, rates of depressive symptoms in medical residents have been reported to be in the range of 30%. CONCLUSION: A survey of pharmacy residents found that the rate of depressive symptoms, as measured by the PHQ-9, was higher than reported rates in the U.S. general population. PMID- 29472511 TI - Development and implementation of an antimicrobial lock therapy guideline in a pediatric hospital. AB - PURPOSE: The development and implementation of an antimicrobial lock therapy guideline at a large pediatric hospital are described. SUMMARY: Central venous access devices (CVADs) are essential in the medical management of patients requiring long-term total parenteral nutrition, chemotherapy, or hemodialysis. However, the use of a CVAD carries a significant risk of the development of central line-associated bloodstream infection (CLABSI). Antimicrobial lock therapy is indicated for patients with CLABSIs who have no signs of exit site or tunnel infection and for whom catheter salvage is a goal. An antimicrobial lock therapy guideline was developed and implemented at a large pediatric hospital by an interprofessional team consisting of providers specializing in CVAD care. Development and implementation of the guideline included a needs assessment, a literature review, determination of patient selection criteria, addition of compounding formulations, development of administration techniques, and education. In all 10 instances of lock therapy in the 18 months after guideline implementation, the criteria for use were met; in 60% of those instances, patients received care from an infectious diseases physician. Each of the available lock solutions was used at least once during the 18-month period. CONCLUSION: Overall, implementation of a guideline on administration of antimicrobial lock therapy was successful. Nine patients received antimicrobial lock therapy in the 18 months after policy implementation; although 2 had their line removed (1 due to repeated line infections), neither required line replacement. PMID- 29472512 TI - Developing an electronic system to manage and track emergency medications. AB - PURPOSE: The development of a Web-based program to track and manage emergency medications with radio frequency identification (RFID) is described. SUMMARY: At the Cleveland Clinic, medication kit restocking records and dispense locations were historically documented using a paper record-keeping system. The Cleveland Clinic investigated options to replace the paper-based tracking logs with a Web based program that could track the real-time location and inventory of emergency medication kits. Vendor collaboration with a board of pharmacy (BOP) compliance inspector and pharmacy personnel resulted in the creation of a dual barcoding system using medication and pocket labels. The Web-based program was integrated with a Cleveland Clinic-developed asset tracking system using active RFID tags to give the real-time location of the medication kit. The Web-based program and the asset tracking system allowed identification of kits nearing expiration or containing recalled medications. Conversion from a paper-based system to a Web based program began in October 2013. After 119 days, data were evaluated to assess the success of the conversion. Pharmacists spent an average of 27 minutes per day approving medication kits during the postimplementation period versus 102 minutes daily using the paper-based system, representing a 74% decrease in pharmacist time spent on this task. Prospective reports are generated monthly to allow the manager to assess the expected workload and adjust staffing for the next month. CONCLUSION: Implementation of a BOP-approved Web-based system for managing and tracking emergency medications with RFID integration decreased pharmacist review time, minimized compliance risk, and increased access to real time data. PMID- 29472513 TI - Stability of an extemporaneously compounded minoxidil oral suspension. AB - PURPOSE: Results of a study to determine the stability of an extemporaneously compounded minoxidil oral suspension under various temperature and stress conditions are reported. METHODS: Commercially available minoxidil tablets (10 mg) were crushed to a fine powder, and predetermined amounts of 2 suspending vehicles were added to produce a 1-mg/mL suspension, which was stored in glass bottles at room temperature (25 +/- 2 degrees C) or in a refrigerator (4 +/- 2 degrees C). To simulate daily patient use, 5 days weekly 1 bottle of the suspension was removed from refrigerated storage and shaken and 0.5 mL of the contents discarded. At each specified time point, samples were analyzed in duplicate (n = 6 for each test condition) using a validated high-performance liquid chromatography method. Samples were visually observed and their pH measured at each time point. Microbiological studies were performed on day 0 and at week 24. RESULTS: The mean percentage of initial minoxidil concentration remaining in all refrigerated samples exceeded 90% throughout the 24-week study, with no change in appearance, pH, microbial activity, odor, or redispersibility. During storage at room temperature, the suspension exhibited a color change at week 4, with slight sedimentation after 6 weeks, although minoxidil recovery exceeded 90% for 10 weeks. CONCLUSION: An extemporaneously compounded minoxidil oral suspension was stable for 24 weeks when stored in a refrigerator. This suspension can be used for up to 3 weeks when stored at room temperature. PMID- 29472514 TI - Patient nonadherence to filling discharge medication prescriptions from the emergency department: Barriers and clinical implications. AB - PURPOSE: Barriers to and clinical implications of patient nonadherence to filling discharge medication prescriptions from the emergency department (ED) were evaluated. METHODS: This was a retrospective, observational analysis of patients discharged from the ED from April 2013 through May 2015 with medication prescriptions. Patients age 18-89 years who were seen in the ED and did not retrieve discharge medication prescriptions from the onsite, 24-hour ED discharge pharmacy were included in this study. Patients who did not pick up prescriptions were called and asked about barriers to prescription filling. These charts were then retrospectively reviewed and categorized. The primary study outcome was the frequency of nonadherence to filling discharge medications prescribed during the ED visit at the ED outpatient pharmacy. Secondary outcomes included identifying barriers to medication adherence, the rate of return ED visits within 30 days of ED discharge, and the rate of 30-day hospital admissions. Associations between patient and medication variables and the rates of return ED visits within 30 days of discharge and 30-day hospital admissions were analyzed. RESULTS: Of the 4,444 patients discharged from the ED with a prescription to be filled at the satellite pharmacy, 510 were nonadherent. Of these patients, 505 had complete chart information available for evaluation. A large proportion of nonadherent patients revisited the ED within 30 days of ED discharge. Multivariate logistic regression found payer class, ethnicity, and sex were independently associated with return ED visits. CONCLUSION: The majority of patients who received a prescription during an ED visit filled their discharge medications. Sex, ethnicity, and payer class were independently associated with nonadherence.

PMID- 29472515 TI - Development of a standardized approach for managing opioids in adults with chronic noncancer pain. AB - PURPOSE: The implementation of a chronic pain protocol (CPP) and its effects on the management of long-term opioid therapy are described. SUMMARY: The CPP used at a federally qualified health center and primary care clinic was updated in 2015 and included a prescribing ceiling in morphine equivalent dose (MED) per day and standardized the prescribing of chronic opioids. Intermittent urine drug screening performed at least once annually was added as a requirement of the pain management contract between the provider and the patient. An electronic report was developed to identify patients who were receiving long-term opioid therapy at the clinic. The clinical pharmacists identified patients from the report whose long-term opioid doses were over the clinic-recommended MED threshold, needed a pain contract, or were due for a urine drug screen. The number of patients for whom long-term opioids were prescribed decreased for all clinicians, including an 88% reduction by nurse practitioners. Over 12 months, 97 fewer patients with chronic pain were treated with a long-term opioid at the clinic. The number of patients with pain contracts increased by 22.9% (p < 0.001), and the number of patients who had a urine drug screen over a 12-month period increased by 18.3% (p = 0.0016). CONCLUSION: The implementation of a CPP and the development of electronic reports to track provider adherence to the protocol led to a reduction in the number of chronic pain patients receiving long-term opioid therapy. The number of patients with pain contracts increased. PMID- 29472517 TI - Nordihydroguaiaretic Acid, a Lignan from Larrea tridentata (Creosote Bush), Protects Against American Lifestyle-Induced Obesity Syndrome Diet-Induced Metabolic Dysfunction in Mice. AB - To determine the effects of nordihydroguaiaretic acid (NDGA) on metabolic and molecular changes in response to feeding a typical American fast food or Western diet, mice were fed an American lifestyle-induced obesity syndrome (ALIOS) diet and subjected to metabolic analysis. Male C57BL/6J mice were randomly assigned to the ALIOS diet, the ALIOS diet supplemented with NDGA (NDGA+ALIOS), or a control diet and were maintained on the specific diet for 8 weeks. Mice fed the ALIOS diet showed increased body, liver, and epididymal fat pad weight as well as increased plasma alanine transaminase (ALT) and aspartate aminotransferase (AST) levels (a measure of liver injury) and liver triglyceride content. Coadministration of NDGA normalized body and epididymal fat pad weight, ALT and AST levels, and liver triglycerides. NDGA treatment also improved insulin sensitivity but not glucose intolerance in mice fed the ALIOS diet. In mice fed the NDGA+ALIOS diet, NDGA supplementation induced peroxisome proliferator activated receptor alpha (PPARalpha; the master regulator of fatty acid oxidation) and mRNA levels of carnitine palmitoyltransferases Cpt1c and Cpt2, key genes involved in fatty acid oxidation, compared with the ALIOS diet. NDGA significantly reduced liver endoplasmic reticulum (ER) stress response C/EBP homologous protein, compared with chow or the ALIOS diet, and also ameliorated ALIOS diet-induced elevation of apoptosis signaling protein, caspase 3. Likewise, NDGA downregulated the ALIOS diet-induced mRNA levels of Pparg, fatty acid synthase Fasn, and diacylglycerol acyltransferase Dgat2 NDGA treatment of ALIOS fed mice upregulated the hepatic expression of antioxidant enzymes, glutathione peroxidase 4, and peroxiredoxin 3 proteins. In conclusion, we provide evidence that NDGA improves metabolic dysregulation by simultaneously modulating the PPARalpha transcription factor and key genes involved in fatty acid oxidation, key antioxidant and lipogenic enzymes, and apoptosis and ER stress signaling pathways. PMID- 29472519 TI - Genetic Mosaicism and Cancer: Cause and Effect. AB - Increasing theoretical and experimental evidence suggests that the genomes of both normal and cancer cells are subject to continuous changes as a result of copying errors during replication, defects in chromosome segregation during mitosis, and direct chemical attacks by reactive oxygen species. The process of cellular genetic diversification begins during embryonic development and continues throughout life, leading to the phenomenon of somatic mosaicism. New information about the genetic diversity of cells composing the body makes us reconsider the existing concepts of cancer etiology and pathogenesis. Here, I suggest that a progressively deteriorating microenvironment ("soil") generates the cancerous "seed" and favors its development. Cancer Res; 78(6); 1375-8. (c)2018 AACR. PMID- 29472518 TI - Mass Spectrometry-Based Proteomics Reveals Potential Roles of NEK9 and MAP2K4 in Resistance to PI3K Inhibition in Triple-Negative Breast Cancers. AB - Activation of PI3K signaling is frequently observed in triple-negative breast cancer (TNBC), yet PI3K inhibitors have shown limited clinical activity. To investigate intrinsic and adaptive mechanisms of resistance, we analyzed a panel of patient-derived xenograft models of TNBC with varying responsiveness to buparlisib, a pan-PI3K inhibitor. In a subset of patient-derived xenografts, resistance was associated with incomplete inhibition of PI3K signaling and upregulated MAPK/MEK signaling in response to buparlisib. Outlier phosphoproteome and kinome analyses identified novel candidates functionally important to buparlisib resistance, including NEK9 and MAP2K4. Knockdown of NEK9 or MAP2K4 reduced both baseline and feedback MAPK/MEK signaling and showed synthetic lethality with buparlisib in vitro A complex in/del frameshift in PIK3CA decreased sensitivity to buparlisib via NEK9/MAP2K4-dependent mechanisms. In summary, our study supports a role for NEK9 and MAP2K4 in mediating buparlisib resistance and demonstrates the value of unbiased omic analyses in uncovering resistance mechanisms to targeted therapy.Significance: Integrative phosphoproteogenomic analysis is used to determine intrinsic resistance mechanisms of triple-negative breast tumors to PI3K inhibition.

PMID- 29472520 TI - Trajectories of body mass index and waist circumference in four Peruvian settings at different level of urbanisation: the CRONICAS Cohort Study. AB - BACKGROUND: Studies have reported the incidence/risk of becoming obese, but few have described the trajectories of body mass index (BMI) and waist circumference (WC) over time, especially in low/middle-income countries. We assessed the trajectories of BMI and WC according to sex in four sites in Peru. METHODS: Data from the population-based CRONICAS Cohort Study were analysed. We fitted a population-averaged model by using generalised estimating equations. The outcomes of interest, with three data points over time, were BMI and WC. The exposure variable was the factorial interaction between time and study site. RESULTS: At baseline mean age was 55.7 years (SD: 12.7) and 51.6% were women. Mean follow-up time was 2.5 years (SD: 0.4). Over time and across sites, BMI and WC increased linearly. The less urbanised sites showed a faster increase than more urbanised sites, and this was also observed after sex stratification. Overall, the fastest increase was found for WC compared with BMI. Compared with Lima, the fastest increase in WC was in rural Puno (coefficient=0.73, P<0.001), followed by urban Puno (coefficient=0.59, P=0.001) and Tumbes (coefficient=0.22, P=0.088). CONCLUSIONS: There was a linear increase in BMI and WC across study sites, with the greatest increase in less urbanised areas. The ongoing urbanisation process, common to Peru and other low/middle-income countries, is accompanied by different trajectories of increasing obesity-related markers. PMID- 29472521 TI - Breast Metaplastic Squamous Cell Carcinoma Diagnosed with Fine Needle and Core Biopsy: A Case Study. AB - BACKGROUND Breast metaplastic squamous cell carcinoma (SCC) is a rare primary breast carcinoma, and overexpression of HER2 in this carcinoma is extremely uncommon. CASE REPORT We presented a case of a 48-year-old Asian female with breast metaplastic SCC. Fine needle aspiration biopsy (FNAB) and core needle biopsy (CNB) of the lesion were taken prior to surgical resection. FNAB smears demonstrated highly atypical squamous cells and a diagnosis positive for malignancy was rendered. CNB and a surgical resection specimen revealed invasive squamous carcinoma with keratin pearl formation and intercellular bridges. Further study demonstrated this was an unusual metaplastic SCC case with basal HER2 (+) phenotype. HER2 has been linked to poor prognosis and response to therapy. CONCLUSIONS The pathological diagnosis of the breast metaplastic SCC was made initially by FNAB and CNB. Identification of basal-HER2 (+) phenotype was critical for selection of hormonal therapies and chemotherapy. PMID- 29472522 TI - Finite Element Study of Implant Subsidence and Medial Tilt in Agility Ankle Replacement. AB - BACKGROUND Clinical studies indicate that in total ankle arthroplasty, postoperative implant subsidence and medial tilt become two significant concerns of the ankle replacement system, and which are associated with the contact between the bones and the talar component. Up to now, little attention has focused on the contact between the bones and the talar component. MATERIAL AND METHODS In order to address implant subsidence and medial tilt, one three dimensional finite element model of contact between the bone and the talar components was built with the material properties of the cancellous bone interpolated from the experimental data, which represents variation of material properties through the cancellous bones. The finite element model was used to study the following: variation of the Young's modulus of the bones, stiffness of the talar component, loading direction, and loading magnitude with the implant subsidence. RESULTS The computational results reveal that a variety of Young's modulus of the cancellous bones causes the medial tilting of the talar component and that big plastic strains are associated with tilting. The implant subsidence increases from 0.169 mm to 0.269 mm when the loading changes from 272 kg to 408 kg. However, to the contrary, the implant subsidence decreases from 0.2676 mm to 0.1783 mm when Young's modulus of the bones increases 50%. However, the implant subsidence shows little change with a different Young's modulus of the talar component from 88 GPa to 132 GPa. CONCLUSIONS Our study indicates that a variety of different Young's modulus of the cancellous bones cause the medial tilting of the talar component. To solve subsidence and tilting, both the contact area and the variation of material properties should be taken into account. PMID- 29472523 TI - Association of Graft Effluent Parameters with Donor Body Mass Index, Graft Quality, and Post-Transplant Events. AB - BACKGROUND We evaluated whether effluent parameters prior to reperfusion correlate with post-transplant outcomes in liver transplant recipients. MATERIAL AND METHODS Concentrations of high mobility group box 1 protein (HMGB1), uncleaved cytokeratin-18 (M65), caspase-cleaved cytokeratin 18 fragment (M30), alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transpeptidase (GGT), and alkaline phosphatase (ALP) were measured in effluent samples from 53 adult liver recipients (42 survived for 1 year and 11 did not survive). RESULTS Effluent concentrations of ALP (p=0.006), AST (p=0.050), and Ca++ (p=0.003) were higher in patients with bacteriemia in the first post transplant year and ALP (p=0.015) was higher in patients with early graft dysfunction (EAD). Multivariate analysis of effluent parameters showed that Ca++ >0.30 mmol/l (p=0.012, odds ratio [OR]=7.12, confidence interval [CI]=1.56 32.58), and ALP >=27 IU/l (p=0.033, OR=5.31, CI=1.14-27.74) were significantly associated with 1-year post-transplant bacteriemia, whereas ALP >=27 IU/l (p=0.020, OR=5.56, CI=1.32-23.46) was significantly associated with EAD. HMGB1 >54 pg/ml (p=0.008, OR=6.05, CI=1.59-23.00) was significantly associated with the donor body mass index (p=0.008, OR=6.05, CI=1.59-23.00) and fatty liver (p=0.005, OR=11.68, CI=2.10-64.01). CONCLUSIONS Effluent parameters are indicators of liver quality and predict the outcome of liver transplantation. High effluent Ca++ and ALP are risk factors of post-transplant bacteriemia. In addition, high ALP is a risk factor of EAD, and high HMGB1 is an indicator of liver quality. PMID- 29472524 TI - PU.1/microRNA-142-3p targets ATG5/ATG16L1 to inactivate autophagy and sensitize hepatocellular carcinoma cells to sorafenib. AB - Sorafenib is currently the only systemic agent approved for treatment of advanced hepatocellular carcinoma (HCC). However, intrinsic and acquired resistance to sorafenib remains a great challenge with respect to improving the prognoses of patients with HCC. The cyto-protective functions of autophagy have been suggested as a potential mechanism by which chemoresistance or targeted drug resistance occurs in tumour cells. In the present study, miR-142-3p was identified as a novel autophagy-regulating microRNA (miRNA) that plays a vital role in sorafenib resistance in HCC cells. Gain- and loss-of-function assays revealed that ectopic miR-142-3p upregulation sensitized HCC cells to sorafenib by reducing sorafenib induced autophagy, enhancing sorafenib-induced apoptosis and inhibiting cell growth, whereas miR-142-3p inhibition exerted contrasting effects. Bioinformatics analysis and luciferase reporter and rescue assays showed that autophagy-related 5 (ATG5) and autophagy-related 16-like 1 (ATG16L1) are potential targets through which miR-142-3p regulates autophagy inhibition. Furthermore, we verified that PU.1 regulated the expression of miR-142-3p in conjunction with our cellular experiments and the related results in the literature. Our findings show that targeting the PU.1-miR-142-3p-ATG5/ATG16L1 axis may be a useful therapeutic strategy for preventing cyto-protective autophagy to overcome sorafenib resistance. PMID- 29472525 TI - Timescales of water accumulation in magmas and implications for short warning times of explosive eruptions. AB - Water plays a key role in magma genesis, differentiation, ascent and, finally, eruption. Despite the recognized crucial function of water, there are still several issues that continue to blur our view about its role in magmatic systems. What are the timescales of H2O accumulation in crystallizing magmas? What are the ascent rates of water-rich residual melts leading to explosive eruptions? Here, we track the timescale of water accumulation in a residual melt resulting from crystallization of a hydrous CO2-bearing magmatic mass stored at mid- to deep crustal levels in a subduction-related geodynamic setting. Our results indicate that, after a repose period ranging from few to several thousand years, water rich melts with water concentrations larger than 6-9 wt.% can migrate towards the Earth surface in very short timescales, on the order of days or even hours, possibly triggering explosive eruptions with short warning times and devoid of long-term geophysical precursors.

AB - During the last century, inorganic oxide compounds laid foundations for materials synthesis, characterization, and technology translation by adding new functions into devices previously dominated by main-group element semiconductor compounds. Today, compounds with multiple anions beyond the single-oxide ion, such as oxyhalides and oxyhydrides, offer a new materials platform from which superior functionality may arise. Here we review the recent progress, status, and future prospects and challenges facing the development and deployment of mixed-anion compounds, focusing mainly on oxide-derived materials. We devote attention to the crucial roles that multiple anions play during synthesis, characterization, and in the physical properties of these materials. We discuss the opportunities enabled by recent advances in synthetic approaches for design of both local and overall structure, state-of-the-art characterization techniques to distinguish unique structural and chemical states, and chemical/physical properties emerging from the synergy of multiple anions for catalysis, energy conversion, and electronic materials.

PMID- 29472527 TI - Hints on ATGL implications in cancer: beyond bioenergetic clues. AB - Among metabolic rearrangements occurring in cancer cells, lipid metabolism alteration has become a hallmark, aimed at sustaining accelerated proliferation. In particular, fatty acids (FAs) are dramatically required by cancer cells as signalling molecules and membrane building blocks, beyond bioenergetics. Along with de novo biosynthesis, free FAs derive from dietary sources or from intracellular lipid droplets, which represent the storage of triacylglycerols (TAGs). Adipose triglyceride lipase (ATGL) is the rate-limiting enzyme of lipolysis, catalysing the first step of intracellular TAGs hydrolysis in several tissues. However, the roles of ATGL in cancer are still neglected though a putative tumour suppressor function of ATGL has been envisaged, as its expression is frequently reduced in different human cancers (e.g., lung, muscle, and pancreas). In this review, we will introduce lipid metabolism focusing on ATGL functions and regulation in normal cell physiology providing also speculative perspectives on potential non-energetic functions of ATGL in cancer. In particular, we will discuss how ATGL is implicated, mainly through the peroxisome proliferator-activated receptor-alpha (PPAR-alpha) signalling, in inflammation, redox homoeostasis and autophagy, which are well-known processes deregulated during cancer formation and/or progression. PMID- 29472529 TI - A novel microRNA identified in hepatocellular carcinomas is responsive to LEF1 and facilitates proliferation and epithelial-mesenchymal transition via targeting of NFIX. AB - Hepatocellular carcinoma (HCC) is one of the most prevalent cancers. It has been demonstrated that various cellular microRNAs (miRNAs) play an important role in HCC development. Here, we analyzed the miRNA profile in HCC tissues by Solexa sequencing, and we identified a novel microRNA, miR-HCC1, which is upregulated in HCC tissues. Further experiments showed that miR-HCC1 promoted HCC cell proliferation in vivo and in vitro, and migration and invasion resulting from the epithelial-mesenchymal transition (EMT) process. Nuclear factor I/X (NFIX), which inhibited cell proliferation, migration and invasion in HCC cells, was identified as a direct and functional target of miR-HCC1. Furthermore, lymphoid enhancer binding factor 1 (LEF1), a transcription factor, was shown to bind the promoter of miR-HCC1 and activate its expression. Collectively, these results indicate that LEF1-upregulated miR-HCC1 functions as an oncogene through the negative regulation of NFIX expression, which links the LEF1/miR-HCC1/NFIX axis to contribute to cell proliferation, migration and invasion of HCC cells and could provide novel insights into miRNA function and hepatocarcinogenesis and potential biomarkers for HCC. PMID- 29472530 TI - Histone deacetylase inhibitor ITF2357 leads to apoptosis and enhances doxorubicin cytotoxicity in preclinical models of human sarcoma. AB - Sarcomas are rare tumors with generally poor prognosis, for which current therapies have shown limited efficacy. Histone deacetylase inhibitors (HDACi) are emerging anti-tumor agents; however, little is known about their effect in sarcomas. By using established and patient-derived sarcoma cells with different subtypes, we showed that the pan-HDACi, ITF2357, potently inhibited in vitro survival in a p53-independent manner. ITF2357-mediated cell death implied the activation of mitochondrial apoptosis, as attested by induction of pro-apoptotic BH3-only proteins and a caspases-dependent mechanism. ITF2357 also induced autophagy, which protected sarcoma cells from apoptotic cell death. ITF2357 activated forkhead box (FOXO) 1 and 3a transcription factors and their downstream target genes, however, silencing of both FOXO1 and 3a did not protect sarcoma cells against ITF2357-induced apoptosis and upregulated FOXO4 and 6. Notably, ITF2357 synergized with Doxorubicin to induce cell death of established and patient-derived sarcoma cells. Furthermore, combination treatment strongly impaired xenograft tumor growth in vivo, when compared to single treatments, suggesting that combination of ITF2357 with Doxorubicin has the potential to enhance sensitization in different preclinical models of sarcoma. Overall, our study highlights the therapeutic potential of ITF2357, alone or in rational combination therapies, for bone and soft tissue sarcomas management. PMID- 29472531 TI - Efficacy of the highly selective focal adhesion kinase inhibitor BI 853520 in adenocarcinoma xenograft models is linked to a mesenchymal tumor phenotype. AB - Focal adhesion kinase (FAK), a non-receptor tyrosine kinase, has attracted interest as a target for pharmacological intervention in malignant diseases. Here, we describe BI 853520, a novel ATP-competitive inhibitor distinguished by high potency and selectivity. In vitro, the compound inhibits FAK autophosphorylation in PC-3 prostate carcinoma cells with an IC50 of 1 nmol/L and blocks anchorage-independent proliferation of PC-3 cells with an EC50 of 3 nmol/L, whereas cells grown in conventional surface culture are 1000-fold less sensitive. In mice, the compound shows long half-life, high volume of distribution and high oral bioavailability; oral dosing of immunodeficient mice bearing subcutaneous PC-3 prostate adenocarcinoma xenografts resulted in rapid, long-lasting repression of FAK autophosphorylation in tumor tissue. Daily oral administration of BI 853520 to nude mice at doses of 50 mg/kg was well tolerated for prolonged periods of time. In a diverse panel of 16 subcutaneous adenocarcinoma xenograft models in nude mice, drug treatment resulted in a broad spectrum of outcomes, ranging from group median tumor growth inhibition values >100% and tumor regression in subsets of animals to complete lack of sensitivity. Biomarker analysis indicated that high sensitivity is linked to a mesenchymal tumor phenotype, initially defined by loss of E-cadherin expression and subsequently substantiated by gene set enrichment analysis. Further, we obtained microRNA expression profiles for 13 models and observed that hsa-miR-200c-3p expression is strongly correlated with efficacy (R2 = 0.889). BI 853520 is undergoing evaluation in early clinical trials. PMID- 29472532 TI - Co-inhibition of BET proteins and NF-kappaB as a potential therapy for colorectal cancer through synergistic inhibiting MYC and FOXM1 expressions. AB - The bromodomain and extra-terminal domain inhibitors (BETi) are promising epigenetic drugs for the treatment of various cancers through suppression of oncogenic transcription factors. However, only a subset of colorectal cancer (CRC) cells response to BETi. We investigate additional agents that could be combined with BETi to overcome this obstacle. JQ1-resistant CRC cells were used for screening of the effective combination therapies with JQ1. RNA-seq was performed to explore the mechanism of synergistic effect. The efficacy of combinational treatment was tested in the CRC cell line- and patient-derived xenograft (PDX) models. In BETi-sensitive CRC cells, JQ1 also impaired tumor angiogenesis through the c-myc/miR-17-92/CTGF+THBS1 axis. CTGF knockdown moderately counteracted anti-angiogenic effect of JQ1 and led to partially attenuated tumor regression. JQ1 decreased c-myc expression and NF-kappaB activity in BETi-sensitive CRC cells but not in resistant cells. Bortezomib synergistically sensitized BETi-resistant cells to the JQ1 treatment, and JQ1+Bortezomib induced G2/M arrest in CRC cells. Mechanistically, inhibition of NF-kappaB by Bortezomib or NF-kappaB inhibitor or IKK1/2 siRNA all rendered BETi resistant cells more sensitive to BETi by synergistic repression of c-myc, which in turn induces GADD45s' expression, and by synergistic repression of FOXM1 which in turn inhibit G2/M checkpoint genes' expression. Activation of NF-kappaB by IkappaBalpha siRNA induced resistance to JQ1 in BETi-sensitive CRC cells. Last, JQ1+Bortezomib inhibited tumor growth and angiogenesis in CRC cell line xenograft model and four PDX models. Our results indicate that anti-angiogenic effect of JQ1 plays a vital role in therapeutic effect of JQ1 in CRC, and provide a rationale for combined inhibition of BET proteins and NF-kappaB as a potential therapy for CRC. PMID- 29472533 TI - Input-output maps are strongly biased towards simple outputs. AB - Many systems in nature can be described using discrete input-output maps. Without knowing details about a map, there may seem to be no a priori reason to expect that a randomly chosen input would be more likely to generate one output over another. Here, by extending fundamental results from algorithmic information theory, we show instead that for many real-world maps, the a priori probability P(x) that randomly sampled inputs generate a particular output x decays exponentially with the approximate Kolmogorov complexity [Formula: see text] of that output. These input-output maps are biased towards simplicity. We derive an upper bound P(x) ? [Formula: see text], which is tight for most inputs. The constants a and b, as well as many properties of P(x), can be predicted with minimal knowledge of the map. We explore this strong bias towards simple outputs in systems ranging from the folding of RNA secondary structures to systems of coupled ordinary differential equations to a stochastic financial trading model. PMID- 29472534 TI - Thermal influences on spontaneous rock dome exfoliation. AB - Rock domes, with their onion-skin layers of exfoliation sheets, are among the most captivating landforms on Earth. Long recognized as integral in shaping domes, the exact mechanism(s) by which exfoliation occurs remains enigmatic, mainly due to the lack of direct observations of natural events. In August 2014, during the hottest days of summer, a granitic dome in California, USA, spontaneously exfoliated; witnesses observed extensive cracking, including a ~8000 kg sheet popping into the air. Subsequent exfoliation episodes during the following two summers were recorded by instrumentation that captured-for the first time-exfoliation deformation and stress conditions. Here we show that thermal cycling and cumulative dome surface heating can induce subcritical cracking that culminates in seemingly spontaneous exfoliation. Our results indicate that thermal stresses-largely discounted in dome formation literature can play a key role in triggering exfoliation and therefore may be an important control for shaping domes worldwide. PMID- 29472535 TI - EGF receptor kinase suppresses ciliogenesis through activation of USP8 deubiquitinase. AB - Ciliogenesis is generally inhibited in dividing cells, however, it has been unclear which signaling cascades regulate the phenomenon. Here, we report that epidermal growth factor receptor (EGFR) kinase suppresses ciliogenesis by directly phosphorylating the deubiquitinase USP8 on Tyr-717 and Tyr-810 in RPE1 cells. These phosphorylations elevate the deubiquitinase activity, which then stabilizes the trichoplein-Aurora A pathway, an inhibitory mechanism of ciliogenesis. EGFR knockdown and serum starvation result in ciliogenesis through downregulation of the USP8-trichoplein-Aurora A signal. Moreover, primary cilia abrogation, which is induced upon IFT20 or Cep164 depletion, ameliorates the cell cycle arrest of EGFR knockdown cells. The present data reveal that the EGFR-USP8 trichoplein-Aurora A axis is a critical signaling cascade that restricts ciliogenesis in dividing cells, and functions to facilitate cell proliferation. We further show that usp8 knockout zebrafish develops ciliopathy-related phenotypes including cystic kidney, suggesting that USP8 is a regulator of ciliogenesis in vertebrates. PMID- 29472536 TI - Spatial organization of bacterial populations in response to oxygen and carbon counter-gradients in pore networks. AB - Microbial activity in soil is spatially heterogeneous often forming spatial hotspots that contribute disproportionally to biogeochemical processes. Evidence suggests that bacterial spatial organization contributes to the persistence of anoxic hotspots even in unsaturated soils. Such processes are difficult to observe in situ at the microscale, hence mechanisms and time scales relevant for bacterial spatial organization remain largely qualitative. Here we develop an experimental platform based on glass-etched micrometric pore networks that mimics resource gradients postulated in soil aggregates to observe spatial organization of fluorescently tagged aerobic and facultative anaerobic bacteria. Two initially intermixed bacterial species, Pseudomonas putida and Pseudomonas veronii, segregate into preferential regions promoted by opposing gradients of carbon and oxygen (such persistent coexistence is not possible in well-mixed cultures). The study provides quantitative visualization and modeling of bacterial spatial organization within aggregate-like hotspots, a key step towards developing a mechanistic representation of bacterial community organization in soil pores. PMID- 29472537 TI - Programmed hierarchical patterning of bacterial populations. AB - Modern genetic tools allow the dissection and emulation of fundamental mechanisms shaping morphogenesis in multicellular organisms. Several synthetic genetic circuits for control of multicellular patterning have been reported to date. However, hierarchical induction of gene expression domains has received little attention from synthetic biologists, despite its importance in biological self organization. Here we report a synthetic genetic system implementing population based AND-logic for programmed autonomous induction of bacterial gene expression domains. We develop a ratiometric assay for bacteriophage T7 RNA polymerase activity and use it to systematically characterize different intact and split enzyme variants. We then utilize the best-performing variant to build a three color patterning system responsive to two different homoserine lactones. We validate the AND gate-like behavior of this system both in cell suspension and in surface culture. Finally, we use the synthetic circuit in a membrane-based spatial assay to demonstrate programmed hierarchical patterning of gene expression across bacterial populations. PMID- 29472538 TI - HDAC1 and HDAC2 integrate checkpoint kinase phosphorylation and cell fate through the phosphatase-2A subunit PR130. AB - Checkpoint kinases sense replicative stress to prevent DNA damage. Here we show that the histone deacetylases HDAC1/HDAC2 sustain the phosphorylation of the checkpoint kinases ATM, CHK1 and CHK2, activity of the cell cycle gatekeeper kinases WEE1 and CDK1, and induction of the tumour suppressor p53 in response to stalled DNA replication. Consequently, HDAC inhibition upon replicative stress promotes mitotic catastrophe. Mechanistically, HDAC1 and HDAC2 suppress the expression of PPP2R3A/PR130, a regulatory subunit of the trimeric serine/threonine phosphatase 2 (PP2A). Genetic elimination of PR130 reveals that PR130 promotes dephosphorylation of ATM by PP2A. Moreover, the ablation of PR130 slows G1/S phase transition and increases the levels of phosphorylated CHK1, replication protein A foci and DNA damage upon replicative stress. Accordingly, stressed PR130 null cells are very susceptible to HDAC inhibition, which abrogates the S phase checkpoint, induces apoptosis and reduces the homologous recombination protein RAD51. Thus, PR130 controls cell fate decisions upon replicative stress. PMID- 29472539 TI - A regulatory circuit of two lncRNAs and a master regulator directs cell fate in yeast. AB - Transcription of long noncoding RNAs (lncRNAs) regulates local gene expression in eukaryotes. Many examples of how a single lncRNA controls the expression of an adjacent or nearby protein-coding gene have been described. Here we examine the regulation of a locus consisting of two contiguous lncRNAs and the master regulator for entry into yeast meiosis, IME1. We find that the cluster of two lncRNAs together with several transcription factors form a regulatory circuit by which IME1 controls its own promoter and thereby promotes its own expression. Inhibition or stimulation of this unusual feedback circuit affects timing and rate of IME1 accumulation, and hence the ability for cells to enter meiosis. Our data demonstrate that orchestrated transcription through two contiguous lncRNAs promotes local gene expression and determines a critical cell fate decision. PMID- 29472540 TI - Exploiting genetic variation to uncover rules of transcription factor binding and chromatin accessibility. AB - Single-nucleotide variants that underlie phenotypic variation can affect chromatin occupancy of transcription factors (TFs). To delineate determinants of in vivo TF binding and chromatin accessibility, we introduce an approach that compares ChIP-seq and DNase-seq data sets from genetically divergent murine erythroid cell lines. The impact of discriminatory single-nucleotide variants on TF ChIP signal enables definition at single base resolution of in vivo binding characteristics of nuclear factors GATA1, TAL1, and CTCF. We further develop a facile complementary approach to more deeply test the requirements of critical nucleotide positions for TF binding by combining CRISPR-Cas9-mediated mutagenesis with ChIP and targeted deep sequencing. Finally, we extend our analytical pipeline to identify nearby contextual DNA elements that modulate chromatin binding by these three TFs, and to define sequences that impact kb-scale chromatin accessibility. Combined, our approaches reveal insights into the genetic basis of TF occupancy and their interplay with chromatin features. PMID- 29472542 TI - Active colloids as mobile microelectrodes for unified label-free selective cargo transport. AB - Utilization of active colloids to transport both biological and inorganic cargo has been widely examined in the context of applications ranging from targeted drug delivery to sample analysis. In general, carriers are customized to load one specific target via a mechanism distinct from that driving the transport. Here we unify these tasks and extend loading capabilities to include on-demand selection of multiple nano/micro-sized targets without the need for pre-labelling or surface functionalization. An externally applied electric field is singularly used to drive the active cargo carrier and transform it into a mobile floating electrode that can attract (trap) or repel specific targets from its surface by dielectrophoresis, enabling dynamic control of target selection, loading and rate of transport via the electric field parameters. In the future, dynamic selectivity could be combined with directed motion to develop building blocks for bottom-up fabrication in applications such as additive manufacturing and soft robotics. PMID- 29472541 TI - Periosteum contains skeletal stem cells with high bone regenerative potential controlled by Periostin. AB - Bone regeneration relies on the activation of skeletal stem cells (SSCs) that still remain poorly characterized. Here, we show that periosteum contains SSCs with high bone regenerative potential compared to bone marrow stromal cells/skeletal stem cells (BMSCs) in mice. Although periosteal cells (PCs) and BMSCs are derived from a common embryonic mesenchymal lineage, postnatally PCs exhibit greater clonogenicity, growth and differentiation capacity than BMSCs. During bone repair, PCs can efficiently contribute to cartilage and bone, and integrate long-term after transplantation. Molecular profiling uncovers genes encoding Periostin and other extracellular matrix molecules associated with the enhanced response to injury of PCs. Periostin gene deletion impairs PC functions and fracture consolidation. Periostin-deficient periosteum cannot reconstitute a pool of PCs after injury demonstrating the presence of SSCs within periosteum and the requirement of Periostin in maintaining this pool. Overall our results highlight the importance of analyzing periosteum and PCs to understand bone phenotypes.

AB - Retinitis pigmentosa (RP) is a group of inherited retinal degenerative diseases causing progressive loss of photoreceptors. Numerous gene mutations are identified to be related with RP, but epigenetic modifications may also be involved in the pathogenesis. Previous studies suggested that both DNA methylation and histone acetylation regulate photoreceptor cell death in RP mouse models. However, the role of histone methylation in RP has never been investigated. In this study, we found that trimethylation of several lysine sites of histone H3, including lysine 27 (H3K27me3), increased in the retinas of rd1 mice. Histone methylation inhibitor DZNep significantly reduced the calpain activity, delayed the photoreceptor loss, and improved ERG response of rd1 retina. RNA-sequencing indicated that DZNep synergistically acts on several molecular pathways that regulate photoreceptor survival in rd1 retina, including PI3K-Akt and photoreceptor differentiation pathways, revealing the therapeutic potential of DZNep for RP treatment. PI3K-Akt pathway and H3K27me3 form a feedback loop in rd1 retina, thus PI3K inhibitor LY294002 reduces phosphorylation of Ezh2 at serine 21 and enhances H3K27me3 deposition, and inhibiting H3K27me3 by DZNep can activate PI3K-Akt pathway by de-repressing gene expression of PI3K subunits Pik3r1 and Pik3r3. These findings suggest that histone methylation, especially H3K27me3 deposition is a novel mechanism and therapeutic target for retinal degenerative diseases, similar to H3K27me3-mediated ataxia-telangiectasia in Atm -/- mouse. PMID- 29472545 TI - Dynamic behavior of a rotary nanomotor in argon environments. AB - When argon is used as a protecting gas in the fabrication or working environment of a nanodevice, absorption of some argon atoms onto the surface of the device lead to different responses. In this work, the rotation of the rotor in a carbon nanotube (CNT)-based rotary nanomotor in argon environment is investigated. In the rotary nanomotor, two outer CNTs act as the stator and are used to constrain the inner CNT (i.e., the rotor). The rotor is driven to rotate by the stator due to their collision during thermal vibration of their atoms. A stable rotational frequency (SRF) of the rotor occurs when the rotor reaches a dynamic equilibrium state. The value of the SRF decreases exponentially with an increase in the initial argon density. At dynamic equilibrium date, some of the argon atoms rotate synchronously with the rotor when they are absorbed onto either internal or external surface of the rotor. The interaction between the rest of the argon atoms and the rotor is stronger at higher densities of argon, resulting in lower values of the SRF. These principles provide insight for future experimentation and fabrication of such rotary nanomotor. PMID- 29472546 TI - CXCR4 can induce PI3Kdelta inhibitor resistance in ABC DLBCL. PMID- 29472547 TI - FISSA: A neuropil decontamination toolbox for calcium imaging signals. AB - In vivo calcium imaging has become a method of choice to image neuronal population activity throughout the nervous system. These experiments generate large sequences of images. Their analysis is computationally intensive and typically involves motion correction, image segmentation into regions of interest (ROIs), and extraction of fluorescence traces from each ROI. Out of focus fluorescence from surrounding neuropil and other cells can strongly contaminate the signal assigned to a given ROI. In this study, we introduce the FISSA toolbox (Fast Image Signal Separation Analysis) for neuropil decontamination. Given pre defined ROIs, the FISSA toolbox automatically extracts the surrounding local neuropil and performs blind-source separation with non-negative matrix factorization. Using both simulated and in vivo data, we show that this toolbox performs similarly or better than existing published methods. FISSA requires only little RAM, and allows for fast processing of large datasets even on a standard laptop. The FISSA toolbox is available in Python, with an option for MATLAB format outputs, and can easily be integrated into existing workflows. It is available from Github and the standard Python repositories. PMID- 29472548 TI - Arginase-II activates mTORC1 through myosin-1b in vascular cell senescence and apoptosis. AB - Type-II L-arginine:ureahydrolase, arginase-II (Arg-II), is shown to activate mechanistic target of rapamycin complex 1 (mTORC1) pathway and contributes to cell senescence and apoptosis. In an attempt to elucidate the underlying mechanism, we identified myosin-1b (Myo1b) as a mediator. Overexpression of Arg II induces re-distribution of lysosome and mTOR but not of tuberous sclerosis complex (TSC) from perinuclear area to cell periphery, dissociation of TSC from lysosome and activation of mTORC1-ribosomal protein S6 kinase 1 (S6K1) pathway. Silencing Myo1b prevents all these alterations induced by Arg-II. By overexpressing Myo1b or its mutant with point mutation in its pleckstrin homology (PH) domain we further demonstrate that this effect of Myo1b is dependent on its PH domain that is required for Myo1b-lysosome association. Notably, Arg-II promotes association of Myo1b with lysosomes. In addition, we show that in senescent vascular smooth muscle cells with elevated endogenous Arg-II, silencing Myo1b prevents Arg-II-mediated lysosomal positioning, dissociation of TSC from lysosome, mTORC1 activation and cell apoptosis. Taken together, our study demonstrates that Myo1b mediates the effect of Arg-II in activating mTORC1-S6K1 through promoting peripheral lysosomal positioning, that results in spatial separation and thus dissociation of TSC from lysosome, leading to hyperactive mTORC1-S6K1 signaling linking to cellular senescence/apoptosis. PMID- 29472549 TI - Directed gas phase formation of silicon dioxide and implications for the formation of interstellar silicates. AB - Interstellar silicates play a key role in star formation and in the origin of solar systems, but their synthetic routes have remained largely elusive so far. Here we demonstrate in a combined crossed molecular beam and computational study that silicon dioxide (SiO2) along with silicon monoxide (SiO) can be synthesized via the reaction of the silylidyne radical (SiH) with molecular oxygen (O2) under single collision conditions. This mechanism may provide a low-temperature path-in addition to high-temperature routes to silicon oxides in circumstellar envelopes possibly enabling the formation and growth of silicates in the interstellar medium necessary to offset the fast silicate destruction. PMID- 29472550 TI - PIM1 mediates epithelial-mesenchymal transition by targeting Smads and c-Myc in the nucleus and potentiates clear-cell renal-cell carcinoma oncogenesis. AB - Emerging evidence has shown that the PIM serine/threonine kinase family, including PIM1, PIM2 and PIM3, is associated with tumour progression towards metastasis. PIM1, an attractive molecular target, has been identified as a potential prognostic biomarker for haematological and epithelial malignancies. However, to date, the potential regulatory roles and molecular mechanisms by which PIM1 affects the development and progression of cancers, including clear cell renal-cell carcinoma (ccRCC), remain largely unknown. Herein, we present the first evidence that PIM1 is aberrantly overexpressed in human ccRCC tissues and cell lines and positively correlated with human ccRCC progression. In our study, depletion of PIM1 attenuated ccRCC cell proliferation, colony formation, migration, invasion and angiogenesis, suggesting that PIM1 expression may be a cancer-promoting event in ccRCC. Mechanistically, we observed that PIM1 could interact with Smad2 or Smad3 in the nucleus and subsequently phosphorylate Smad2 and Smad3 to induce the expression of transcription factors, including ZEB1, ZEB2, Snail1, Snail2 and Twist, to promote epithelial-mesenchymal transition (EMT). In addition, PIM1-mediated phosphorylation of c-Myc activates the expression of the above transcription factors to synergistically promote EMT but does not activate Smads. Collectively, our results demonstrate that aberrant expression of PIM1 contributes to ccRCC development and progression. Moreover, our data reveal a potential molecular mechanism in which PIM1 mediates crosstalk between signalling pathways, including different Smad proteins and c-Myc, which target downstream transcription factors (ZEB1, ZEB2, Snail1, Snail2 and Twist) to trigger EMT. Together, our data suggest that PIM1 may be a potential therapeutic target for ccRCC patients. PMID- 29472551 TI - Enhancement of methane production from Cotton Stalk using different pretreatment techniques. AB - China produces large amount of cotton stalk (CS) residues as agricultural biomass, which are incinerated on-site, causing air pollution. The high organic content of CS could be utilized for biogas production, but the direct digestion without pretreatment always leads to a low methane yield and biodegradability, due to the complicated structure of lignocellulose. In order to search best fitting pretreatment methods in effective anaerobic digestion (AD) of CS, effects of various pretreatments including KOH, NaOH, Ca(OH)2, alkali hydrogen peroxide (AHP), H2SO4, H3PO4 and steam explosion (SE) were studied. It was seen that all treatments resulted in varying methane yields. Among all the pretreatments, acid pretreatment is not suitable for AD of CS. The results showed that the highest cumulative methane yield (CMY) of 192.4 mL.gVS-1 was obtained after 3% AHP pretreatment of CS, and the methane yield improved by 254.3% than the untreated CS. Therefore, AHP treatment was proven to be an efficient pretreatment technique. XRD and FTIR analyses had shown that pretreated CS had favorable structural changes. This research is beneficial in developing environment friendly and cost-effective pretreatment technologies to utilize CS for methane production in future application. PMID- 29472552 TI - Plasma ceramide levels are altered in low and normal birth weight men in response to short-term high-fat overfeeding. AB - Low birth weight (LBW) individuals have an increased risk of developing insulin resistance and type 2 diabetes compared with normal birth weight (NBW) individuals. We hypothesised that LBW individuals exhibit an increased fatty acid flux into lipogenesis in non-adipose tissue with a resulting accumulation of lipotoxic lipids, including ceramides, in the blood. Therefore, we measured fasting plasma levels of 27 ceramides in 18 young, healthy, LBW men and 25 NBW controls after an isocaloric control diet and a 5-day high-fat, high-calorie diet by HPLC-HRMS. LBW men did not show elevated plasma ceramide levels after the control or high-fat, high-calorie diet. An increased fatty acid oxidation rate in these individuals during both diets may limit ceramide synthesis and thereby compensate for a likely increased fatty acid load to non-adipose tissue. Interestingly, LBW and NBW men decreased d18:0-18:1/d18:1-18:0 and d18:1 24:2/d18:2-24:1 levels and increased the d18:0-24:1a level in response to overfeeding. Plasma d18:0-24:1a and total ceramide levels were positively associated with the fasting blood glucose level and endogenous glucose production after the control diet, and the total ceramide level was in addition positively associated with hepatic insulin resistance. Further studies are needed to determine if lipotoxicity contributes to insulin resistance in LBW individuals. PMID- 29472553 TI - Systemic Homeostasis in Metabolome, Ionome, and Microbiome of Wild Yellowfin Goby in Estuarine Ecosystem. AB - Data-driven approaches were applied to investigate the temporal and spatial changes of 1,022 individuals of wild yellowfin goby and its potential interaction with the estuarine environment in Japan. Nuclear magnetic resonance (NMR)-based metabolomics revealed that growth stage is a primary factor affecting muscle metabolism. Then, the metabolic, elemental and microbial profiles of the pooled samples generated according to either the same habitat or sampling season as well as the river water and sediment samples from their habitats were measured using NMR spectra, inductively coupled plasma optical emission spectrometry and next generation 16 S rRNA gene sequencing. Hidden interactions in the integrated datasets such as the potential role of intestinal bacteria in the control of spawning migration, essential amino acids and fatty acids synthesis in wild yellowfin goby were further extracted using correlation clustering and market basket analysis-generated networks. Importantly, our systematic analysis of both the seasonal and latitudinal variations in metabolome, ionome and microbiome of wild yellowfin goby pointed out that the environmental factors such as the temperature play important roles in regulating the body homeostasis of wild fish. PMID- 29472554 TI - Reshaping the phonon energy landscape of nanocrystals inside a terahertz plasmonic nanocavity. AB - Phonons (quanta of collective vibrations) are a major source of energy dissipation and drive some of the most relevant properties of materials. In nanotechnology, phonons severely affect light emission and charge transport of nanodevices. While the phonon response is conventionally considered an inherent property of a nanomaterial, here we show that the dipole-active phonon resonance of semiconducting (CdS) nanocrystals can be drastically reshaped inside a terahertz plasmonic nanocavity, via the phonon strong coupling with the cavity vacuum electric field. Such quantum zero-point field can indeed reach extreme values in a plasmonic nanocavity, thanks to a mode volume well below lambda3/107. Through Raman measurements, we find that the nanocrystals within a nanocavity exhibit two new "hybridized" phonon peaks, whose spectral separation increases with the number of nanocrystals. Our findings open exciting perspectives for engineering the optical phonon response of functional nanomaterials and for implementing a novel platform for nanoscale quantum optomechanics.

AB - Cellulose-pulping requires chemicals such as Cl2, ClO2, H2O2, and O2. The black liquor (BL) generated exhibits a high chemical oxygen demand (COD), five-day biochemical oxygen demand (BOD5), and chlorophenol content, along with an augmented colour and increased pH. BL is often discharged into water bodies, where it has a negative impact on the environment. Towards that end, laccases are of great interest for bioremediation, since they can degrade aromatic and non aromatic compounds while reducing O2 to water instead of H2O2. As such, we evaluated Pleurotus ostreatus and Pichia pastoris (which produces rPOXA 1B laccase) in the treatment of synthetic BL (SBL) in an "in vitro" modified Kraft process followed by CuO/TiO2/visible light photocatalysis. Treating SBL with P. ostreatus viable biomass (VB) followed by CuO/TiO2/visible light photocatalysis resulted in 80.3% COD removal and 70.6% decolourisation. Toxic compounds such as 2-methylphenol, 4-methylphenol, and 2-methoxyphenol were eliminated. Post-treated SBL exhibited low phytotoxicity, as evidenced by a Lactuca sativa L seed germination index (GI) > 50%. Likewise, SBL treatment with P. pastoris followed by VB/CuO/TiO2/visible light photocatalysis resulted in 63.7% COD removal and 46% decolourisation. Moreover, this treatment resulted in the elimination of most unwanted compounds, with the exception of 4-chlorophenol. The Lactuca sativa L seed GI of the post-treated SBL was 40%, indicating moderate phytotoxicity.

AB - The recurrent gain-of-function JAK2V617F mutation confers growth factor independent proliferation for hematopoietic cells and is a major contributor to the pathogenesis of myeloproliferative neoplasms (MPN). The lack of complete response in most patients treated with the JAK1/2 inhibitor ruxolitinib indicates the need for identifying novel therapeutic strategies. Metformin is a biguanide that exerts selective antineoplastic activity in hematological malignancies. In the present study, we investigate and compare effects of metformin and ruxolitinib alone and in combination on cell signaling and cellular functions in JAK2V617F-positive cells. In JAK2V617F-expressing cell lines, metformin treatment significantly reduced cell viability, cell proliferation, clonogenicity, and cellular oxygen consumption and delayed cell cycle progression. Metformin reduced cyclin D1 expression and RB, STAT3, STAT5, ERK1/2 and p70S6K phosphorylation. Metformin plus ruxolitinib demonstrated more intense reduction of cell viability and induction of apoptosis compared to monotherapy. Notably, metformin reduced Ba/F3 JAK2V617F tumor burden and splenomegaly in Jak2V617F knock-in-induced MPN mice and spontaneous erythroid colony formation in primary cells from polycythemia vera patients. In conclusion, metformin exerts multitarget antileukemia activity in MPN: downregulation of JAK2/STAT signaling and mitochondrial activity. Our exploratory study establishes novel molecular mechanisms of metformin and ruxolitinib action and provides insights for development of alternative/complementary therapeutic strategies for MPN.

AB - Lithium-oxygen cells, in which lithium peroxide forms in solution rather than on the electrode surface, can sustain relatively high cycling rates but require redox mediators to charge. The mediators are oxidised at the electrode surface and then oxidise lithium peroxide stored in the cathode. The kinetics of lithium peroxide oxidation has received almost no attention and yet is crucial for the operation of the lithium-oxygen cell. It is essential that the molecules oxidise lithium peroxide sufficiently rapidly to sustain fast charging. Here, we investigate the kinetics of lithium peroxide oxidation by several different classes of redox mediators. We show that the reaction is not a simple outer sphere electron transfer and that the steric structure of the mediator molecule plays an important role. The fastest mediator studied could sustain a charging current of up to 1.9 A cm-2, based on a model for a porous electrode described here.

PMID- 29472560 TI - Landscape topography structures the soil microbiome in arctic polygonal tundra. AB - In the Arctic, environmental factors governing microbial degradation of soil carbon (C) in active layer and permafrost are poorly understood. Here we determined the functional potential of soil microbiomes horizontally and vertically across a cryoperturbed polygonal landscape in Alaska. With comparative metagenomics, genome binning of novel microbes, and gas flux measurements we show that microbial greenhouse gas (GHG) production is strongly correlated to landscape topography. Active layer and permafrost harbor contrasting microbiomes, with increasing amounts of Actinobacteria correlating with decreasing soil C in permafrost. While microbial functions such as fermentation and methanogenesis were dominant in wetter polygons, in drier polygons genes for C mineralization and CH4 oxidation were abundant. The active layer microbiome was poised to assimilate N and not to release N2O, reflecting low N2O flux measurements. These results provide mechanistic links of microbial metabolism to GHG fluxes that are needed for the refinement of model predictions. PMID- 29472561 TI - Human mitochondrial pyruvate carrier 2 as an autonomous membrane transporter. AB - The active transport of glycolytic pyruvate across the inner mitochondrial membrane is thought to involve two mitochondrial pyruvate carrier subunits, MPC1 and MPC2, assembled as a 150 kDa heterotypic oligomer. Here, the recombinant production of human MPC through a co-expression strategy is first described; however, substantial complex formation was not observed, and predominantly individual subunits were purified. In contrast to MPC1, which co-purifies with a host chaperone, we demonstrated that MPC2 homo-oligomers promote efficient pyruvate transport into proteoliposomes. The derived functional requirements and kinetic features of MPC2 resemble those previously demonstrated for MPC in the literature. Distinctly, chemical inhibition of transport is observed only for a thiazolidinedione derivative. The autonomous transport role for MPC2 is validated in cells when the ectopic expression of human MPC2 in yeast lacking endogenous MPC stimulated growth and increased oxygen consumption. Multiple oligomeric species of MPC2 across mitochondrial isolates, purified protein and artificial lipid bilayers suggest functional high-order complexes. Significant changes in the secondary structure content of MPC2, as probed by synchrotron radiation circular dichroism, further supports the interaction between the protein and ligands. Our results provide the initial framework for the independent role of MPC2 in homeostasis and diseases related to dysregulated pyruvate metabolism. PMID- 29472562 TI - Galphai-mediated TRPC4 activation by polycystin-1 contributes to endothelial function via STAT1 activation. AB - Hypertension and aneurysm are frequently associated with autosomal dominant polycystic kidney disease (ADPKD) caused by polycystin-1 (PC1) mutations, which is closely related to endothelial dysfunction. PC1 is an atypical G-protein coupled receptor that activates G-proteins by self-cleavage; currently, however, the molecular and cellular mechanisms of the associated intracellular signaling and ion channel activation remain poorly elucidated. Here, we report an activation mechanism of a calcium-permeable canonical transient receptor potential 4 (TRPC4) channel by PC1 and its endothelial function. We found that the inhibitory Galphai3 protein selectively bound to the G-protein-binding domain on the C-terminus of PC1. The dissociation of Galphai3 upon cleavage of PC1 increased TRPC4 activity. Calcium influx through TRPC4 activated the transcription factor STAT1 to regulate cell proliferation and death. The down regulation of PC1/TRPC4/STAT1 disrupted migration of endothelial cell monolayers, leading to an increase in endothelial permeability. These findings contribute to greater understanding of the high risk of aneurysm in patients with ADPKD. PMID- 29472563 TI - Non-Invasive Radiofrequency Field Treatment of 4T1 Breast Tumors Induces T-cell Dependent Inflammatory Response. AB - Previous work using non-invasive radiofrequency field treatment (RFT) in cancer has demonstrated its therapeutic potential as it can increase intratumoral blood perfusion, localization of intravenously delivered drugs, and promote a hyperthermic intratumoral state. Despite the well-known immunologic benefits that febrile hyperthermia can induce, an investigation of how RFT could modulate the intra-tumoral immune microenvironment had not been studied. Thus, using an established 4T1 breast cancer model in immune competent mice, we demonstrate that RFT induces a transient, localized, and T-cell dependent intratumoral inflammatory response. More specifically we show that multi- and singlet-dose RFT promote an increase in tumor volume in immune competent Balb/c mice, which does not occur in athymic nude models. Further leukocyte subset analysis at 24, 48, and 120 hours after a single RFT show a rapid increase in tumoral trafficking of CD4+ and CD8+ T-cells 24 hours post-treatment. Additional serum cytokine analysis reveals an increase in numerous pro-inflammatory cytokines and chemokines associated with enhanced T-cell trafficking. Overall, these data demonstrate that non-invasive RFT could be an effective immunomodulatory strategy in solid tumors, especially for enhancing the tumoral trafficking of lymphocytes, which is currently a major hindrance of numerous cancer immunotherapeutic strategies. PMID- 29472564 TI - Inhibitory modulation of cytochrome c oxidase activity with specific near infrared light wavelengths attenuates brain ischemia/reperfusion injury. AB - The interaction of light with biological tissue has been successfully utilized for multiple therapeutic purposes. Previous studies have suggested that near infrared light (NIR) enhances the activity of mitochondria by increasing cytochrome c oxidase (COX) activity, which we confirmed for 810 nm NIR. In contrast, scanning the NIR spectrum between 700 nm and 1000 nm revealed two NIR wavelengths (750 nm and 950 nm) that reduced the activity of isolated COX. COX inhibitory wavelengths reduced mitochondrial respiration, reduced the mitochondrial membrane potential (DeltaPsim), attenuated mitochondrial superoxide production, and attenuated neuronal death following oxygen glucose deprivation, whereas NIR that activates COX provided no benefit. We evaluated COX-inhibitory NIR as a potential therapy for cerebral reperfusion injury using a rat model of global brain ischemia. Untreated animals demonstrated an 86% loss of neurons in the CA1 hippocampus post-reperfusion whereas inhibitory NIR groups were robustly protected, with neuronal loss ranging from 11% to 35%. Moreover, neurologic function, assessed by radial arm maze performance, was preserved at control levels in rats treated with a combination of both COX-inhibitory NIR wavelengths. Taken together, our data suggest that COX-inhibitory NIR may be a viable non pharmacologic and noninvasive therapy for the treatment of cerebral reperfusion injury. PMID- 29472566 TI - Wetter summers can intensify departures from natural variability in a warming climate. AB - Climate change can drive local climates outside the range of their historical year-to-year variability, straining the adaptive capacity of ecological and human communities. We demonstrate that dependencies between climate variables can produce larger and earlier departures from natural variability than is detectable in individual variables. Using the example of summer temperature (Tx) and precipitation (Pr), we show that this departure intensification effect occurs when the bivariate climate change trajectory is misaligned with the dominant mode of joint historical variability. Departure intensification is evident in all six CMIP5 models that we examined: 23% (9-34%) of the global land area of each model exhibits a pronounced increase in 2sigma anomalies in the Tx-Pr regime relative to Tx or Pr alone. Observational data suggest that summer Tx-Pr correlations in distinct regions on all continents are sufficient to produce departure intensification. Precipitation can be an important driver of multivariate climate change signals relative to natural variability, despite typically having a much weaker univariate signal than temperature. PMID- 29472565 TI - Endogenous insensitivity to the Orco agonist VUAA1 reveals novel olfactory receptor complex properties in the specialist fly Mayetiola destructor. AB - Insect olfactory receptors are routinely expressed in heterologous systems for functional characterisation. It was recently discovered that the essential olfactory receptor co-receptor (Orco) of the Hessian fly, Mayetiola destructor (Mdes), does not respond to the agonist VUAA1, which activates Orco in all other insects analysed to date. Here, using a mutagenesis-based approach we identified three residues in MdesOrco, located in different transmembrane helices as supported by 3D modelling, that confer sensitivity to VUAA1. Reciprocal mutations in Drosophila melanogaster (Dmel) and the noctuid moth Agrotis segetum (Aseg) Orcos diminish sensitivity of these proteins to VUAA1. Additionally, mutating these residues in DmelOrco and AsegOrco compromised odourant receptor (OR) dependent ligand-induced Orco activation. In contrast, both wild-type and VUAA1 sensitive MdesOrco were capable of forming functional receptor complexes when coupled to ORs from all three species, suggesting unique complex properties in M. destructor, and that not all olfactory receptor complexes are "created" equal. PMID- 29472567 TI - Polyrotaxane-based supramolecular theranostics. AB - The development of smart theranostic systems with favourable biocompatibility, high loading efficiency, excellent circulation stability, potent anti-tumour activity, and multimodal diagnostic functionalities is of importance for future clinical application. The premature burst release and poor degradation kinetics indicative of polymer-based nanomedicines remain the major obstacles for clinical translation. Herein we prepare theranostic shell-crosslinked nanoparticles (SCNPs) using a beta-cyclodextrin-based polyrotaxane (PDI-PCL-b-PEG-RGD?beta-CD NH2) to avoid premature drug leakage and achieve precisely controllable release, enhancing the maximum tolerated dose of the supramolecular nanomedicines. cRGDfK and perylene diimide are chosen as the stoppers of PDI-PCL-b-PEG-RGD?beta-CD-NH2, endowing the resultant SCNPs with excellent integrin targeting ability, photothermal effect, and photoacoustic capability. In vivo anti-tumour studies demonstrate that drug-loaded SCNPs completely eliminate the subcutaneous tumours without recurrence after a single-dose injection combining chemotherapy and photothermal therapy. These supramolecular nanomedicines also exhibit excellent anti-tumour performance against orthotopic breast cancer and prevent lung metastasis with negligible systemic toxicity. PMID- 29472568 TI - Lack of galectin-3 modifies differentially Notch ligands in bone marrow and spleen stromal cells interfering with B cell differentiation. AB - Galectin-3 (Gal-3) is a beta-galactoside binding protein that controls cell-cell and cell-extracellular matrix interactions. In lymphoid organs, gal-3 inhibits B cell differentiation by mechanisms poorly understood. The B cell development is dependent on tissue organization and stromal cell signaling, including IL-7 and Notch pathways. Here, we investigate possible mechanisms that gal-3 interferes during B lymphocyte differentiation in the bone marrow (BM) and spleen. The BM of gal-3-deficient mice (Lgals3-/- mice) was evidenced by elevated numbers of B220+CD19+c-Kit+IL-7R+ progenitor B cells. In parallel, CD45- bone marrow stromal cells expressed high levels of mRNA IL-7, Notch ligands (Jagged-1 and Delta-like 4), and transcription factors (Hes-1, Hey-1, Hey-2 and Hey-L). The spleen of Lgals3-/- mice was hallmarked by marginal zone disorganization, high number of IgM+IgD+ B cells and CD138+ plasma cells, overexpression of Notch ligands (Jagged 1, Delta-like 1 and Delta-like 4) by stromal cells and Hey-1. Morever, IgM+IgD+ B cells and B220+CD138+ CXCR4+ plasmablasts were significantly increased in the BM and blood of Lgals3-/- mice. For the first time, we demonstrated that gal-3 inhibits Notch signaling activation in lymphoid organs regulating earlier and terminal events of B cell differentiation. PMID- 29472570 TI - The Po Delta is restarting progradation: geomorphological evolution based on a 47 years Earth Observation dataset. AB - From the 1950s, the Po delta, one of the largest anthropogenic world deltas, has been subjected to a fast degradation and shoreline retreat due a marked reduction of sediment supply, mainly controlled by human impacts/factors, including subsidence. Through the interpretation of satellite images, coupled with the analysis of the flow discharge, and of the annual frequency of marine storms, we show that recently (>2010) the Po River has resumed delta progradation, especially in its northern portion. This happens after decades of erosion, followed by alternating regrowth and degradation phases, indicating conditions of substantial stability (1970-2000). Today the delta shows aggradation of new mouth bars at the main distributary mouth, a clear evidence of active constructive processes. The ongoing trend marks a countertendency compared to many deltas worldwide. PMID- 29472569 TI - Cysteine residues are essential for dimerization of Hippo pathway components YAP2L and TAZ. AB - Hippo signalling pathway is an emerging signalling pathway that plays important roles in organ size control, tumorigenesis, metastasis, stress response, apoptosis, stem cell differentiation and renewal during development and tissue homeostasis. Recent studies reported that human serine/threonine protein kinase, Mst1, a core component of the Hippo pathway can be activated through formation of homodimer. However, it is still unclear whether or not other components of the Hippo pathway are also regulated through dimerization. Here we provide the first evidence that Hippo components and oncoprotein YAP2L and TAZ can form homodimer in vitro and in vivo by forming disulphide bond through cysteine residue(s). We have also shown that the homodimers of YAP2L/TAZ are more stable and showed more oncogenic behaviour than their corresponding monomers as revealed by colony formation and cell transformation assay. Since cysteine post-translational regulation plays important roles in redox signalling, tumorigenesis and drug resistance, further studies on the functional effect of this dimerization through post-translational modulation of cysteine residues in YAP2L/TAZ will provide a significant contribution to our understanding of the roles of YAP2L/TAZ in cancer development and therapy. PMID- 29472571 TI - Serum profile changes in postpartum women with a history of childhood maltreatment: a combined metabolite and lipid fingerprinting study. AB - Childhood maltreatment (CM) can increase the risk of adverse health consequences in adulthood. A deeper insight in underlying biological pathways would be of high clinical relevance for early detection and intervention. The untargeted investigation of all detectable metabolites and lipids in biological samples represents a promising new avenue to identify so far unknown biological pathways associated with CM. Using an untargeted approach, liquid chromatography-mass spectrometry (LC-MS) was performed on peripheral blood serum samples collected three months postpartum from 105 women with varying degrees of CM exposure. Comprehensive univariate and multivariate statistical analyses consistently identified eight biomarker candidates putatively belonging to antioxidant-, lipid , and endocannabinoid-associated pathways, which differentiated between women with and without CM. Classification algorithms allowed for clear prediction of the CM status with high accuracy scores (~80-90%). Similar results were obtained when excluding all women with a lifetime psychiatric diagnosis. In order to confirm the identities of these promising biomarker candidates, LC-MS/MS analysis was applied, confirming one of the metabolites as bilirubin IXa, a potent antioxidant with immunomodulatory properties. In sum, our results suggest novel pathways that could explain long-term effects of CM on health and disease by influencing biological patterns associated with energy metabolism, inflammation, and oxidative stress. PMID- 29472572 TI - Onset and Evolution of Southern Annular Mode-Like Changes at Centennial Timescale. AB - The Southern Westerly Winds (SWW) are the surface expression of geostrophic winds that encircle the southern mid-latitudes. In conjunction with the Southern Ocean, they establish a coupled system that not only controls climate in the southern third of the world, but is also closely connected to the position of the Intertropical Convergence Zone and CO2 degassing from the deep ocean. Paradoxically, little is known about their behavior since the last ice age and relationships with mid-latitude glacier history and tropical climate variability. Here we present a lake sediment record from Chilean Patagonia (51 degrees S) that reveals fluctuations of the low-level SWW at mid-latitudes, including strong westerlies during the Antarctic Cold Reversal, anomalously low intensity during the early Holocene, which was unfavorable for glacier growth, and strong SWW since ~7.5 ka. We detect nine positive Southern Annular Mode-like events at centennial timescale since ~5.8 ka that alternate with cold/wet intervals favorable for glacier expansions (Neoglaciations) in southern Patagonia. The correspondence of key features of mid-latitude atmospheric circulation with shifts in tropical climate since ~10 ka suggests that coherent climatic shifts in these regions have driven climate change in vast sectors of the Southern Hemisphere at centennial and millennial timescales. PMID- 29472573 TI - Optimization of ClpXP activity and protein synthesis in an E. coli extract-based cell-free expression system. AB - Protein degradation is a fundamental process in all living cells and is essential to remove both damaged proteins and intact proteins that are no longer needed by the cell. We are interested in creating synthetic genetic circuits that function in a cell-free expression system. This will require not only an efficient protein expression platform but also a robust protein degradation system in cell extract. Therefore, we purified and tested the activity of E. coli ClpXP protease in cell free transcription-translation (TX-TL) systems that used E. coli S30 cell extract. Surprisingly, our studies showed that purified ClpXP added to the TX-TL system has very low proteolytic activity. The low activity of ClpXP was correlated with the rapid consumption of adenosine triphosphate (ATP) in cell extract. We improved the activity of ClpXP in cell extract by adding exogenous ATP and an energy regeneration system. We then established conditions for both protein synthesis, and protein degradation by ClpXP to occur simultaneously in the TX-TL systems. The optimized conditions for ClpXP activity will be useful for creating tunable synthetic genetic circuits and in vitro synthetic biology. PMID- 29472574 TI - Equal-Spin Andreev Reflection on Junctions of Spin-Resolved Quantum Hall Bulk State and Spin-Singlet Superconductor. AB - The recent development of superconducting spintronics has revealed the spin triplet superconducting proximity effect from a spin-singlet superconductor into a spin-polarized normal metal. In addition recently superconducting junctions using semiconductors are in demand for highly controlled experiments to engineer topological superconductivity. Here we report experimental observation of Andreev reflection in junctions of spin-resolved quantum Hall (QH) states in an InAs quantum well and the spin-singlet superconductor NbTi. The measured conductance indicates a sub-gap feature and two peaks on the outer side of the sub-gap feature in the QH plateau-transition regime increases. The observed structures can be explained by considering transport with Andreev reflection from two channels, one originating from equal-spin Andreev reflection intermediated by spin-flip processes and second arising from normal Andreev reflection. This result indicates the possibility to induce the superconducting proximity gap in the the QH bulk state, and the possibility for the development of superconducting spintronics in semiconductor devices. PMID- 29472575 TI - Glial cell type-specific changes in spinal dipeptidyl peptidase 4 expression and effects of its inhibitors in inflammatory and neuropatic pain. AB - Altered pain sensations such as hyperalgesia and allodynia are characteristic features of various pain states, and remain difficult to treat. We have shown previously that spinal application of dipeptidyl peptidase 4 (DPP4) inhibitors induces strong antihyperalgesic effect during inflammatory pain. In this study we observed low level of DPP4 mRNA in the rat spinal dorsal horn in physiological conditions, which did not change significantly either in carrageenan-induced inflammatory or partial nerve ligation-generated neuropathic states. In naive animals, microglia and astrocytes expressed DPP4 protein with one and two orders of magnitude higher than neurons, respectively. DPP4 significantly increased in astrocytes during inflammation and in microglia in neuropathy. Intrathecal application of two DPP4 inhibitors tripeptide isoleucin-prolin-isoleucin (IPI) and the antidiabetic drug vildagliptin resulted in robust opioid-dependent antihyperalgesic effect during inflammation, and milder but significant opioid independent antihyperalgesic action in the neuropathic model. The opioid-mediated antihyperalgesic effect of IPI was exclusively related to mu-opioid receptors, while vildagliptin affected mainly delta-receptor activity, although mu- and kappa-receptors were also involved. None of the inhibitors influenced allodynia. Our results suggest pathology and glia-type specific changes of DPP4 activity in the spinal cord, which contribute to the development and maintenance of hyperalgesia and interact with endogenous opioid systems. PMID- 29472576 TI - Broad blocking of MDR efflux pumps by acetylshikonin and acetoxyisovalerylshikonin to generate hypersensitive phenotype of malignant carcinoma cells. AB - Cytotoxic activities of acetylshikonin and acetoxyisovalerylshikonin alone and in combination with chemotherapeutic agents against parental and drug resistant cell lines were determined using the MTT assay. Effects of Shikonin derivatives on BCRP, MDR1 and MRP transcript and protein levels were relatively measured. Finally, accumulation and efflux kinetics were conducted. The results revealed cell- and concentration-dependency of the cell cytotoxicity. Acetylshikonin and acetoxyisovalerylshikonin transiently made the mRNA ocean turbulent, but FACS analyses using fluorescent-labeled antibodies showed no significant change in the MDR-protein levels. Functional kinetics revealed significant block of MDR1, BCRP and MRP transporter in the presence of shikonin derivatives. Maximum accumulation fold changes was quantified to be 4.4 and consequently, acetoxyisovalerylshikonin pretreated EPG85.257RDB cells was chemosensitized to daunorubicin tension 3.1 fold. Although, the MDR blockage was reported to follow time- and cell-dependent patterns, MDR1, BCRP and MRP2 responses to the shikonins are concentration independent. These data suggest uncompetitive transporter blockage behavior of these agents. The results indicated that shikonin derivatives stimulate uptake and reduce efflux of chemotherapeutic agents in the malignant cancer cells, suggesting that chemotherapy in combination with shikonin compounds may be beneficial to cancer cells that overexpress multidrug resistance transporters. PMID- 29472577 TI - Design and Demonstration of Impedance-matched Dual-band Chiral Metasurfaces. AB - We propose a new family of impedance-matched chiral metasurfaces that offer arbitrary polarization control at two different frequencies. To this end, two main problems are addressed: (1) determination of the required surface impedances for a certain user-defined chiral functionality at two frequencies and (2) their physical realization at microwaves. The first milestone is achieved through a proposed synthesis method that combines a semi-analytical method and a nonlinear optimization technique. In particular, the impedances are computed such that the devised chiral metasurface is also impedance-matched to a terminating medium. The chiral metasurfaces are then physically realized at microwaves by cascading layers of rotated arrays of multiple concentric rectangular copper rings. We establish that these proposed unit cells offer distinct dual-resonances that can be arbitrarily and independently tuned for two orthogonal linear polarizations at each of the two operating frequencies. This allows simultaneous physical mapping of the required surface impedances at two frequencies. The versatility and generality of the proposed numerical and physical solutions are demonstrated through two design examples: A dual-band circular polarization selective surface (CPSS) and a dual-band polarization rotator (PR). The dual-band CPSS is further confirmed experimentally at 20 GHz and 30 GHz based on a free-space quasi-optical system. PMID- 29472578 TI - The assassin bug Pristhesancus plagipennis produces two distinct venoms in separate gland lumens. AB - The assassin bug venom system plays diverse roles in prey capture, defence and extra-oral digestion, but it is poorly characterised, partly due to its anatomical complexity. Here we demonstrate that this complexity results from numerous adaptations that enable assassin bugs to modulate the composition of their venom in a context-dependent manner. Gland reconstructions from multimodal imaging reveal three distinct venom gland lumens: the anterior main gland (AMG); posterior main gland (PMG); and accessory gland (AG). Transcriptomic and proteomic experiments demonstrate that the AMG and PMG produce and accumulate distinct sets of venom proteins and peptides. PMG venom, which can be elicited by electrostimulation, potently paralyses and kills prey insects. In contrast, AMG venom elicited by harassment does not paralyse prey insects, suggesting a defensive role. Our data suggest that assassin bugs produce offensive and defensive venoms in anatomically distinct glands, an evolutionary adaptation that, to our knowledge, has not been described for any other venomous animal. PMID- 29472580 TI - Changes in micro-relief during different water erosive stages of purple soil under simulated rainfall. AB - This study investigated the variation characteristics of micro-topography during successive erosive stages of water erosion: splash erosion (SpE), sheet erosion (ShE), and rill erosion (RE). Micro-topography was quantified using surface elevation change, soil roughness (SR) and multifractal model. Results showed that the area of soil surface elevation decay increased gradually with the development of water erosion. With rainfall, the combined effects of the detachment by raindrop impact and the transport of runoff decreased SR, whereas rill erosion contributed to increase SR. With the increase in slope gradient, soil erosion area gradually decreased at the splash erosion stage. By contrast, soil erosion area initially decreased and then increased at the sheet and rill erosion stages. The width of the D q spectra (DeltaD) values increased at the splash erosion stage and then decreased at the sheet and rill erosion stages on the 10 degrees slope, opposite to that on the 15 degrees slope. The DeltaD values decreased with the evolution of water erosive stages on the 20 degrees slope. The slope had an enhancing effect on the evolution of water erosion. In this study, we clarified the essence of micro-topography and laid a theoretical foundation for further understanding diverse hydrological processes. PMID- 29472579 TI - Single-molecule theory of enzymatic inhibition. AB - The classical theory of enzymatic inhibition takes a deterministic, bulk based approach to quantitatively describe how inhibitors affect the progression of enzymatic reactions. Catalysis at the single-enzyme level is, however, inherently stochastic which could lead to strong deviations from classical predictions. To explore this, we take the single-enzyme perspective and rebuild the theory of enzymatic inhibition from the bottom up. We find that accounting for multi conformational enzyme structure and intrinsic randomness should strongly change our view on the uncompetitive and mixed modes of inhibition. There, stochastic fluctuations at the single-enzyme level could make inhibitors act as activators; and we state-in terms of experimentally measurable quantities-a mathematical condition for the emergence of this surprising phenomenon. Our findings could explain why certain molecules that inhibit enzymatic activity when substrate concentrations are high, elicit a non-monotonic dose response when substrate concentrations are low. PMID- 29472581 TI - Wavelength Assignment in Hybrid Quantum-Classical Networks. AB - Optimal wavelength assignment in dense-wavelength-division-multiplexing (DWDM) systems that integrate both quantum and classical channels is studied. In such systems, weak quantum key distribution (QKD) signals travel alongside intense classical signals on the same fiber, where the former can be masked by the background noise induced by the latter. Here, we investigate how optimal wavelength assignment can mitigate this problem. We consider different DWDM structures and various sources of crosstalk and propose several near-optimal wavelength assignment methods that maximize the total secret key rate of the QKD channels. Our numerical results show that the optimum wavelength assignment pattern is commonly consisted of several interspersed quantum and classical bands. Using our proposed techniques, the total secret key rate of quantum channels can substantially be improved, as compared to conventional assignment methods, in the noise dominated regimes. Alternatively, we can maximize the number of QKD users supported under certain key rate constraints. PMID- 29472582 TI - P2X7 receptor regulates osteoclast function and bone loss in a mouse model of osteoporosis. AB - Post-menopausal osteoporosis is a condition that affects millions worldwide and places a huge socio-economic burden on society. Previous research has shown an association of loss of function SNPs in the gene for the purinergic receptor P2X7R with low bone mineral density, increased rates of bone loss and vertebral fractures in post-menopausal women. In this study we use a mouse model of oestrogen deficiency-induced bone loss and the BALB/cJ P2X7R-/- to show that absence of the P2X7R resulted in increased bone loss. Osteoclast precursors were isolated from both BALB/cJ P2X7R-/- and BALB/cJ P2X7R+/+ mice and then cultured in vitro to form mature resorbing osteoclasts. The BALB/cJ P2X7R-/- derived precursors generated slightly more osteoclasts but with a significant reduction in the amount of resorption per osteoclast. Furthermore, when using modified culture conditions osteoclast activity was additionally increased in the absence of the P2X7R suggest that P2X7R may regulate the lifespan and activity of osteoclasts. Finally using mechanical loading as an anabolic stimulus for bone formation, we demonstrated that the increased oestrogen-deficient bone loss could be rescued, even in the absence of P2X7R. This study paves the way for clinical intervention for women with post-menopausal osteoporosis and P2XR7 loss of function polymorphisms.

AB - Quercetin is one of the most abundant flavonoids, present in fruits and vegetables and has been shown to have multiple properties capable of reducing cell growth in cancer cells. Green tea is a widely consumed beverage, known for a potential source of free radical scavenging and anti-cancer activities. Herein, we investigate the in vivo antitumor efficacy of quercetin and green tea in human leukemia. Human tumors were xenografted into NOD/SCID mice. Quercetin and green tea reduced tumor growth in HL-60 xenografts accompanied by decreased expression of anti-apoptotic proteins, BCL-2, BCL-XL and MCL-1 and increased expression of BAX, a pro-apoptotic protein. Moreover, caspase-3 was activated to a greater extent after quercetin and green tea treatment. Quercetin and green tea also mediated G1 phase cell cycle arrest in HL-60 xenografts. Treatment with quercetin and green tea induced conversion of LC3-I to LC3-II as well as activation of autophagy proteins, suggesting that quercetin and green tea initiate the autophagic progression. We have provided evidence that quercetin and green tea induces signaling at the level of apoptosis, cell cycle and autophagy which converge to antigrowth effects in HL-60 xenograft mice suggesting that these compounds may be a compelling ally in cancer treatment. PMID- 29472584 TI - The structure of iPLA2beta reveals dimeric active sites and suggests mechanisms of regulation and localization. AB - Calcium-independent phospholipase A2beta (iPLA2beta) regulates important physiological processes including inflammation, calcium homeostasis and apoptosis. It is genetically linked to neurodegenerative disorders including Parkinson's disease. Despite its known enzymatic activity, the mechanisms underlying iPLA2beta-induced pathologic phenotypes remain poorly understood. Here, we present a crystal structure of iPLA2beta that significantly revises existing mechanistic models. The catalytic domains form a tight dimer. They are surrounded by ankyrin repeat domains that adopt an outwardly flared orientation, poised to interact with membrane proteins. The closely integrated active sites are positioned for cooperative activation and internal transacylation. The structure and additional solution studies suggest that both catalytic domains can be bound and allosterically inhibited by a single calmodulin. These features suggest mechanisms of iPLA2beta cellular localization and activity regulation, providing a basis for inhibitor development. Furthermore, the structure provides a framework to investigate the role of neurodegenerative mutations and the function of iPLA2beta in the brain. PMID- 29472586 TI - Ocean submesoscales as a key component of the global heat budget. AB - Recent studies highlight that oceanic motions associated with horizontal scales smaller than 50 km, defined here as submesoscales, lead to anomalous vertical heat fluxes from colder to warmer waters. This unique transport property is not captured in climate models that have insufficient resolution to simulate these submesoscale dynamics. Here, we use an ocean model with an unprecedented resolution that, for the first time, globally resolves submesoscale heat transport. Upper-ocean submesoscale turbulence produces a systematically-upward heat transport that is five times larger than mesoscale heat transport, with winter-time averages up to 100 W/m2 for mid-latitudes. Compared to a lower resolution model, submesoscale heat transport warms the sea surface up to 0.3 degrees C and produces an upward annual-mean air-sea heat flux anomaly of 4-10 W/m2 at mid-latitudes. These results indicate that submesoscale dynamics are critical to the transport of heat between the ocean interior and the atmosphere, and are thus a key component of the Earth's climate. PMID- 29472585 TI - Estradiol signaling mediates gender difference in visceral adiposity via autophagy. AB - Excessive adiposity (particularly visceral fat mass) increases the risks of developing metabolic syndrome. Women have lower deposit of visceral fat than men, and this pattern becomes diminished postmenopausally, but the underlying mechanism remains largely unknown. Here, we show that the gender difference in visceral fat distribution is controlled by an estradiol-autophagy axis. In C57BL/6J and wild-type control mice, a higher visceral fat mass was detected in the males than in the females, which was associated with lower expression of estrogen receptor alpha (ERalpha) and more active autophagy in males vs. females. However, deletion of ERalpha normalized autophagy activity and abolished the gender difference in visceral adiposity. In line with the adiposity-reducing effect of the ERalpha-autophagy axis, we found that downregulation of ERalpha and increased autophagy activity were required for adipogenesis, while induction of estradiol signaling dampened autophagy and drastically prevented adipogenesis. Mechanistically, the estradiol-ERalpha signaling activated mTOR, which phosphorylated and inhibited ULK1, thereby suppressing autophagy and adipogenesis. Together, our study suggests that the lower visceral adiposity in the females (vs. the males) arises from a more active estradiol-ERalpha signaling, which tunes down autophagy and adipogenesis. PMID- 29472587 TI - Association of BRCA1, ERCC1, RAP80, PKM2, RRM1, RRM2, TS, TSP1, and TXR1 mRNA expression levels between primary tumors and infiltrated regional lymph nodes in patients with resectable non-small cell lung cancer. AB - Differences in gene expression levels between the primary tumors (PTs) and matched regional lymph nodal metastases (LNs) in patients with totally excised non-small cell lung cancer (NSCLC) were explored. Microdissected formalin-fixed paraffin-embedded (FFPE) samples from (PT) and their matched infiltrated LNs, from 239 patients [183 (with matched PT and LNs samples)-case and 56 PT only samples-control cohorts] were analyzed for BRCA1, ERCC1, RAP80, PKM2, RRM1, RRM2, TS, TSP1, and TXR1 mRNA expression by quantitative real-time polymerase-chain reaction (PCR). Moderately positive correlation between the expression of each gene in the PT and the matched LNs was observed. Concordance rates between the PT and the LNs were: BRCA1 (67.7%), ERCC1 (68.4%), PKM2 (63.4%), RAP80 (68.8%), RRM1 (70.9%), RRM2 (69%), TS (72.9%), TSP1 (69.8%), TXR1 (63.7%). Expression levels and their differences were correlated with Relapse-Free Survival (RFS) and Overall Survival (OS). High BRCA1 PT in patients with squamous histology was associated with increased OS (p = 0.036). High TSP1 PT levels were shown to be the only independent prognostic factor for OS and RFS (p = 0.023 and p = 0.007). PKM2 low levels in both PT and matched LNs were associated with better OS irrespective of the underlying histology (p = 0.031). RRM1 discordant levels between PT and matched LNs were associated with worse OS in squamous tumors (p = 0.019) compared to patients with both low expression in PT and LN.TXR1 high levels in both PT and matched LNs were associated with better OS in patients with squamous tumors (p = 0.007).These findings indicate that there is different gene expression between PT and matched LNs which may affect the outcome in early NSCLC and therefore PT's molecular biology should not be the sole determinant for prognostication. PMID- 29472588 TI - Micro-pharmacokinetics: Quantifying local drug concentration at live cell membranes. AB - Fundamental equations for determining pharmacological parameters, such as the binding affinity of a ligand for its target receptor, assume a homogeneous distribution of ligand, with concentrations in the immediate vicinity of the receptor being the same as those in the bulk aqueous phase. It is, however, known that drugs are able to interact directly with the plasma membrane, potentially increasing local ligand concentrations around the receptor. We have previously reported an influence of ligand-phospholipid interactions on ligand binding kinetics at the beta2-adrenoceptor, which resulted in distinct "micro pharmacokinetic" ligand profiles. Here, we directly quantified the local concentration of BODIPY630/650-PEG8-S-propranolol (BY-propranolol), a fluorescent derivative of the classical beta-blocker propranolol, at various distances above membranes of single living cells using fluorescence correlation spectroscopy. We show for the first time a significantly increased ligand concentration immediately adjacent to the cell membrane compared to the bulk aqueous phase. We further show a clear role of both the cell membrane and the beta2-adrenoceptor in determining high local BY-propranolol concentrations at the cell surface. These data suggest that the true binding affinity of BY-propranolol for the beta2 adrenoceptor is likely far lower than previously reported and highlights the critical importance of understanding the "micro-pharmacokinetic" profiles of ligands for membrane-associated proteins. PMID- 29472589 TI - Computationally Efficient Modelling of Stochastic Spatio-Temporal Dynamics in Biomolecular Networks. AB - Measurement techniques in biology are now able to provide data on the trajectories of multiple individual molecules simultaneously, motivating the development of techniques for the stochastic spatio-temporal modelling of biomolecular networks. However, standard approaches based on solving stochastic reaction-diffusion equations are computationally intractable for large-scale networks. We present a novel method for modeling stochastic and spatial dynamics in biomolecular networks using a simple form of the Langevin equation with noisy kinetic constants. Spatial heterogeneity in molecular interactions is decoupled into a set of compartments, where the distribution of molecules in each compartment is idealised as being uniform. The reactions in the network are then modelled by Langevin equations with correcting terms, that account for differences between spatially uniform and spatially non-uniform distributions, and that can be readily estimated from available experimental data. The accuracy and extreme computational efficiency of the approach is demonstrated on a model of the epidermal growth factor receptor network in the human mammary epithelial cell. PMID- 29472590 TI - Elevated Serum Interleukin-34 Level in Patients with Systemic Lupus Erythematosus Is Associated with Disease Activity. AB - We measured the interleukin-34 (IL-34) level in sera from patients with systemic lupus erythematosus (SLE) and discoid lupus erythematosus (DLE) using an enzyme linked immunosorbent assay (ELISA). Blood tests, including assays to determine C reactive protein (CRP), complement (C) 3, C4, immunoglobulin (Ig) A, IgG, IgM, anti-double-stranded DNA antibody (Anti-dsDNA Ab) and hemoglobin (Hb) levels and white blood cell (WBC) and platelet (PLT) counts, were performed using standard methods. Lupus nephritis (LN) was diagnosed according to the American College of Rheumatology (ACR) renal criteria. The SLE disease activity was scored using the SLE Disease Activity Index (SLEDAI). Among the 110 SLE cases, IL-34 could be detected in 79 cases (71.8%). IL-34 was barely detected in the control group. The serum level of IL-34 was significantly higher in the SLE group. No change was observed in the serum IL-34 concentration in the SLE patients regardless of LN status. Correlations were observed between the serum IL-34 level and the disease activity parameters. The SLE patients with detectable IL-34 levels had higher SLEDAI and IgG concentrations and lower C3 and Hb levels than patients with undetectable IL-34 levels. Therefore, IL-34 could be a potential disease activity marker for SLE. PMID- 29472591 TI - Early sclerostin expression explains bone formation inhibition before arthritis onset in the rat adjuvant-induced arthritis model. AB - Periarticular bone loss in rheumatoid arthritis (RA) is considered to be mainly related to synovial inflammation. However, strong bone loss has also described at the time of arthritis onset. Recently, a paradoxical exacerbation of joint damage was described when blocking sclerostin in various arthritis models. Thus, we aimed to determine kinetics of bone loss and its mechanisms in the adjuvant induced arthritis (AIA) rat model of RA. AIA was induced (n = 35) or not (n = 35) at day 0. In addition to well-known arthritis at day 12, we showed with 3D imaging and histomorphometry that bone microstructural alterations occurred early from day 8 post-induction, characterized by cortical porosity and trabecular bone loss. Active osteoclastic surfaces were increased from day 8 with RANKL upregulation. More surprisingly SOST and DKK1 were overexpressed from day 6 and followed by a dramatic decrease in bone formation from day 8. At the time of arthritis onset, SOST and DKK1 returned to control values, but frizzled related protein 1 (SFRP1), proinflammatory cytokines, and MMPs started to increase. Bone alterations before arthritis onset reinforce the hypothesis of an early bone involvement in arthritis. Kinetics of osteocyte markers expression should be considered to refine Wnt inhibitor treatment strategies. PMID- 29472592 TI - GSK3 is a negative regulator of the thermogenic program in brown adipocytes. AB - Brown adipose tissue is a promising therapeutic target in metabolic disorders due to its ability to dissipate energy and improve systemic insulin sensitivity and glucose homeostasis. beta-Adrenergic stimulation of brown adipocytes leads to an increase in oxygen consumption and induction of a thermogenic gene program that includes uncoupling protein 1 (Ucp1) and fibroblast growth factor 21 (Fgf21). In kinase inhibitor screens, we have identified glycogen synthase kinase 3 (GSK3) as a negative regulator of basal and beta-adrenergically stimulated Fgf21 expression in cultured brown adipocytes. In addition, inhibition of GSK3 also caused increased Ucp1 expression and oxygen consumption. beta-Adrenergic stimulation triggered an inhibitory phosphorylation of GSK3 in a protein kinase A (PKA) dependent manner. Mechanistically, inhibition of GSK3 activated the mitogen activated protein kinase (MAPK) kinase 3/6-p38 MAPK-activating transcription factor 2 signaling module. In summary, our data describe GSK3 as a novel negative regulator of beta-adrenergic signaling in brown adipocytes. PMID- 29472593 TI - The relationship between self-enhancing humor and precuneus volume in young healthy individuals with high and low cognitive empathy. AB - A self-enhancing humor style (SEHS) plays an important role in the regulation of negative emotion through humorous perspective-taking. Following the mind-reading theories of humor, we investigated the relationship between gray-matter volume (GMV) of brain areas related to theory of mind and SEHS in young college students, using voxel-based morphometry analysis. We then performed a voxel-wise analysis of covariance to assess any moderation effect of cognitive empathy on the relationship. Results demonstrated that higher SEHS scores were associated with larger GMV of the precuneus in the group with high cognitive empathy, but there was no association in the group with low cognitive empathy. These results suggest that high cognitive empathy and increased precuneus volume can predict greater use of self-enhancing humor in young healthy individuals. PMID- 29472594 TI - Association between autonomic control indexes and mortality in subjects admitted to intensive care unit. AB - This study checks whether autonomic markers derived from spontaneous fluctuations of heart period (HP) and systolic arterial pressure (SAP) and from their interactions with spontaneous or mechanical respiration (R) are associated with mortality in patients admitted to intensive care unit (ICU). Three-hundred consecutive HP, SAP and R values were recorded during the first day in ICU in 123 patients. Population was divided into survivors (SURVs, n = 83) and non-survivors (NonSURVs, n = 40) according to the outcome. SURVs and NonSURVs were aged- and gender-matched. All subjects underwent modified head-up tilt (MHUT) by tilting the bed back rest segment to 60 degrees . Autonomic control indexes were computed using time-domain, spectral, cross-spectral, complexity, symbolic and causality techniques via univariate, bivariate and conditional approaches. SAP indexes derived from time-domain, model-free complexity and symbolic approaches were associated with the endpoint, while none of HP variability markers was. The association was more powerful during MHUT. Linear cross-spectral and causality indexes were useless to separate SURVs from NonSURVs, while nonlinear bivariate symbolic markers were successful. When indexes were combined with clinical scores, only SAP variance provided complementary information. Cardiovascular control variability indexes, especially when derived after an autonomic challenge such as MHUT, can improve mortality risk stratification in ICU. PMID- 29472595 TI - A motif within the armadillo repeat of Parkinson's-linked LRRK2 interacts with FADD to hijack the extrinsic death pathway. AB - In experimental models, both in vivo and cellular, over-expression of Parkinson's linked mutant leucine-rich repeat kinase 2 (LRRK2) is sufficient to induce neuronal death. While several cell death associated proteins have been linked to LRRK2, either as protein interactors or as putative substrates, characterization of the neuronal death cascade remains elusive. In this study, we have mapped for the first time the domain within LRRK2 that mediates the interaction with FADD, thereby activating the molecular machinery of the extrinsic death pathway. Using homology modeling and molecular docking approaches, we have identified a critical motif within the N-terminal armadillo repeat region of LRRK2. Moreover, we show that co-expression of fragments of LRRK2 that contain the FADD binding motif, or deletion of this motif itself, blocks the interaction with FADD, and is neuroprotective. We further demonstrate that downstream of FADD, the mitochondrial proteins Bid and Bax are recruited to the death cascade and are necessary for neuronal death. Our work identifies multiple novel points within neuronal death signaling pathways that could potentially be targeted by candidate therapeutic strategies and highlight how the extrinsic pathway can be activated intracellularly in a pathogenic context. PMID- 29472596 TI - HDAC4 regulates satellite cell proliferation and differentiation by targeting P21 and Sharp1 genes. AB - Skeletal muscle exhibits a high regenerative capacity, mainly due to the ability of satellite cells to replicate and differentiate in response to appropriate stimuli. Epigenetic control is effective at different stages of this process. It has been shown that the chromatin-remodeling factor HDAC4 is able to regulate satellite cell proliferation and commitment. However, its molecular targets are still uncovered. To explain the signaling pathways regulated by HDAC4 in satellite cells, we generated tamoxifen-inducible mice with conditional inactivation of HDAC4 in Pax7+ cells (HDAC4 KO mice). We found that the proliferation and differentiation of HDAC4 KO satellite cells were compromised, although similar amounts of satellite cells were found in mice. Moreover, we found that the inhibition of HDAC4 in satellite cells was sufficient to block the differentiation process. By RNA-sequencing analysis we identified P21 and Sharp1 as HDAC4 target genes. Reducing the expression of these target genes in HDAC4 KO satellite cells, we also defined the molecular pathways regulated by HDAC4 in the epigenetic control of satellite cell expansion and fusion. PMID- 29472597 TI - Role of autophagy in modulating post-maturation aging of mouse oocytes. AB - Mechanisms for post-maturation oocyte aging (PMOA) are not fully understood, and whether autophagy plays any role in PMOA is unknown. To explore the role of autophagy in PMOA, expression of autophagosomes and effects of the autophagy (macro-autophagy) activity on PMOA were observed in mouse oocytes. Oocyte activation rates and active caspase-3 levels increased continuously from 0 to 18 h of in vitro aging. While levels of microtubule-associated protein light chain 3 (LC3)-II increased up to 12 h and decreased thereafter, contents of p62 decreased from 0 to 12 h and then elevated to basal level by 18 h. However, the LC3-II/I ratio remained unchanged following aging in different media or for different times. During in vitro aging up to 12 h, upregulating autophagy with rapamycin or lithium chloride decreased activation susceptibility, cytoplasmic calcium, p62 contents, oxidative stress, caspase-3 activation and cytoplasmic fragmentation while increasing developmental competence, LC3-II contents, LC3-II/I ratio, mitochondrial membrane potential, spindle/chromosome integrity and normal cortical granule distribution. Downregulating autophagy with 3-methyladenine (3 MA) produced opposite effects on all these parameters except cytoplasmic fragmentation. After 12 h of aging culture, however, regulating autophagy with either rapamycin/lithium chloride or 3-MA had no impact on oocyte activation susceptibility. It is concluded that autophagy plays an important role in regulating PMOA. Thus, during the early stage of PMOA, autophagy increases as an adaptive response to prevent further apoptosis, but by the late stage of PMOA, the activation of more caspases blocks the autophagic process leading to severer apoptosis. PMID- 29472598 TI - Climate-Driven Crop Yield and Yield Variability and Climate Change Impacts on the U.S. Great Plains Agricultural Production. AB - Climate variability and trends affect global crop yields and are characterized as highly dependent on location, crop type, and irrigation. U.S. Great Plains, due to its significance in national food production, evident climate variability, and extensive irrigation is an ideal region of investigation for climate impacts on food production. This paper evaluates climate impacts on maize, sorghum, and soybean yields and effect of irrigation for individual counties in this region by employing extensive crop yield and climate datasets from 1968-2013. Variability in crop yields was a quarter of the regional average yields, with a quarter of this variability explained by climate variability, and temperature and precipitation explained these in singularity or combination at different locations. Observed temperature trend was beneficial for maize yields, but detrimental for sorghum and soybean yields, whereas observed precipitation trend was beneficial for all three crops. Irrigated yields demonstrated increased robustness and an effective mitigation strategy against climate impacts than their non-irrigated counterparts by a considerable fraction. The information, data, and maps provided can serve as an assessment guide for planners, managers, and policy- and decision makers to prioritize agricultural resilience efforts and resource allocation or re-allocation in the regions that exhibit risk from climate variability. PMID- 29472599 TI - Acute effects of air pollution on respiratory disease mortalities and outpatients in Southeastern China. AB - The objective of this study was to investigate the potential association between air pollutants and respiratory diseases (RDs). Generalized additive models were used to analyze the effect of air pollutants on mortalities or outpatient visits. The average concentrations of air pollutants in Hangzhou (HZ) were 1.6-2.8 times higher than those in Zhoushan (ZS), except for O3. In a single pollutant model, the increased concentrations of PM2.5, NO2, and SO2 were strongly associated with deaths caused by RD in HZ, while PM2.5 and O3 were associated with deaths caused by RD in ZS. All air pollutants (PM2.5, NO2, SO2, and O3) were strongly associated with outpatient visits for RD in both HZ and ZS. In multiple pollutant models, a significant association was only observed between PM2.5 and the mortality rate of RD patients in both HZ and in ZS. Moreover, strong associations between SO2, NO2, and outpatient visits for RD were observed in HZ and ZS. This study has provided evidence that both the mortality rates and outpatient visits for RD were significantly associated with air pollutants. Furthermore, the results showed that different air pollutant levels lead to regional differences between mortality rates and outpatient visits. PMID- 29472600 TI - PANDA: Protein function prediction using domain architecture and affinity propagation. AB - We developed PANDA (Propagation of Affinity and Domain Architecture) to predict protein functions in the format of Gene Ontology (GO) terms. PANDA at first executes profile-profile alignment algorithm to search against PfamA, KOG, COG, and SwissProt databases, and then launches PSI-BLAST against UniProt for homologue search. PANDA integrates a domain architecture inference algorithm based on the Bayesian statistics that calculates the probability of having a GO term. All the candidate GO terms are pooled and filtered based on Z-score. After that, the remaining GO terms are clustered using an affinity propagation algorithm based on the GO directed acyclic graph, followed by a second round of filtering on the clusters of GO terms. We benchmarked the performance of all the baseline predictors PANDA integrates and also for every pooling and filtering step of PANDA. It can be found that PANDA achieves better performances in terms of area under the curve for precision and recall compared to the baseline predictors. PANDA can be accessed from http://dna.cs.miami.edu/PANDA/ . PMID- 29472601 TI - Reactive Oxygen Species Mediate the Suppression of Arterial Smooth Muscle T-type Ca2+ Channels by Angiotensin II. AB - Vascular T-type Ca2+ channels (CaV3.1 and CaV3.2) play a key role in arterial tone development. This study investigated whether this conductance is a regulatory target of angiotensin II (Ang II), a vasoactive peptide that circulates and which is locally produced within the arterial wall. Patch clamp electrophysiology performed on rat cerebral arterial smooth muscle cells reveals that Ang II (100 nM) inhibited T-type currents through AT1 receptor activation. Blocking protein kinase C failed to eliminate channel suppression, a finding consistent with unique signaling proteins enabling this response. In this regard, inhibiting NADPH oxidase (Nox) with apocynin or ML171 (Nox1 selective) abolished channel suppression highlighting a role for reactive oxygen species (ROS). In the presence of Ni2+ (50 uM), Ang II failed to modulate the residual T-type current, an observation consistent with this peptide targeting CaV3.2. Selective channel suppression by Ang II impaired the ability of CaV3.2 to alter spontaneous transient outward currents or vessel diameter. Proximity ligation assay confirmed Nox1 colocalization with CaV3.2. In closing, Ang II targets CaV3.2 channels via a signaling pathway involving Nox1 and the generation of ROS. This unique regulatory mechanism alters BKCa mediated feedback giving rise to a "constrictive" phenotype often observed with cerebrovascular disease. PMID- 29472602 TI - HPV-transformed cells exhibit altered HMGB1-TLR4/MyD88-SARM1 signaling axis. AB - Cervical cancer is one of the leading causes of cancer death in women worldwide. Persistent infection with high-risk human papillomavirus (HPV) types is the main risk factor for the development of cervical cancer precursor lesions. HPV persistence and tumor development is usually characterized by innate immune system evasion. Alterations in Toll-like receptors (TLR) expression and activation may be important for the control of HPV infections and could play a role in the progression of lesions and tumors. In the present study, we analyzed the mRNA expression of 84 genes involved in TLR signaling pathways. We observed that 80% of the differentially expressed genes were downregulated in cervical cancer cell lines relative to normal keratinocytes. Major alterations were detected in genes coding for several proteins of the TLR signaling axis, including TLR adaptor molecules and genes associated with MAPK pathway, NFkappaB activation and antiviral immune response. In particular, we observed major alterations in the HMGB1-TLR4 signaling axis. Functional analysis also showed that HMGB1 expression is important for the proliferative and tumorigenic potential of cervical cancer cell lines. Taken together, these data indicate that alterations in TLR signaling pathways may play a role in the oncogenic potential of cells expressing HPV oncogenes.

AB - Chronic obstructive pulmonary disease (COPD) is a serious global health problem characterized by chronic airway inflammation, progressive airflow limitation and destruction of lung parenchyma. Remodeling of the bronchial airways in COPD includes changes in both the bronchial epithelium and the subepithelial extracellular matrix (ECM). To explore the impact of an aberrant ECM on epithelial cell phenotype in COPD we developed a new ex vivo model, in which normal human bronchial epithelial (NHBE) cells repopulate and differentiate on decellularized human bronchial scaffolds derived from COPD patients and healthy individuals. By using transcriptomics, we show that bronchial ECM from COPD patients induces differential gene expression in primary NHBE cells when compared to normal bronchial ECM. The gene expression profile indicated altered activity of upstream mediators associated with COPD pathophysiology, including hepatocyte growth factor, transforming growth factor beta 1 and platelet-derived growth factor B, which suggests that COPD-related changes in the bronchial ECM contribute to the defective regenerative ability in the airways of COPD patients. PMID- 29472604 TI - A non-invasive method to directly quantify surface heterogeneity of porous materials. AB - It is extremely challenging to measure the variation of pore surface properties in complex porous systems even though many porous materials have widely differing pore surface properties at microscopic levels. The surface heterogeneity results in different adsorption/desorption behaviors and storage capacity of guest molecules in pores. Built upon the conventional Porod's law scattering theory applicable mainly to porous materials with relatively homogeneous matrices, here we develop a generalized Porod's scattering law method (GPSLM) to study heterogeneous porous materials and directly obtain the variation of scattering length density (SLD) of pore surfaces. As SLD is a function of the chemical formula and density of the matrix, the non-invasive GPSLM provides a way to probe surface compositional heterogeneity, and can be applied to a wide range of heterogeneous materials especially, but not limited to, porous media and colloids, using either neutron or X-ray scattering techniques. PMID- 29472605 TI - DEHP deregulates adipokine levels and impairs fatty acid storage in human SGBS adipocytes. AB - DEHP is a plasticizer which has been used in plastic products of everyday use for decades. Studies in mice and murine cell culture models identified DEHP as an endocrine disruptor that may also act as an obesogen. As this is of high concern in respect of the worldwide obesity epidemic, our aim is the translation of these findings into a human model system. On the basis of DOHaD, we investigated the influence of an environmentally relevant dose of DEHP [50 ug/ml] on adipogenesis in the human cell culture model SGBS. Pre-adipocytes were exposed to DEHP and differentiated into mature adipocytes. At different stages of differentiation, markers of adipogenesis like GLUT4, FABP4, LPL and PPARs, and of signaling pathways like AMPK/ACC2, JAK/STAT and MAPK were analyzed. Functional markers like adipokine secretion and triglyceride content as well as ROS production were measured in mature adipocytes. We found significantly lower expression levels of adipogenic markers, a reduction in lipid accumulation, higher leptin- and reduced adiponectin levels in the supernatant of treated adipocytes. Moreover, ROS production was significantly elevated after DEHP-exposure. In conclusion, DEHP led to lower grade of adipogenic differentiation in human SGBS-adipocytes under the chosen conditions. PMID- 29472606 TI - Nanogels of dual inhibitor-modified hyaluronic acid function as a potent inhibitor of amyloid beta-protein aggregation and cytotoxicity. AB - Inhibition of amyloid beta-protein (Abeta) aggregation is considered as a promising strategy for the prevention and treatment of Alzheimer's disease. Epigallocatechin-3-gallate (EGCG) and curcumin have been recognized as effective inhibitors of Abeta aggregation. Herein, we proposed dual-inhibitor modification of hyaluronic acid (HA) to explore the synergistic effect of the two inhibitors. EGCG-modified HA (EHA) formed dispersed hydrogel structures, while EGCG-curcumin bi-modified HA (CEHA) self-assembled into nanogels like curcumin-modified HA (CHA). Thioflavin T fluorescent assays revealed that the inhibitory effect of CEHA was 69% and 55% higher than EHA and CHA, respectively, and cytotoxicity assays showed that the viability of SH-SY5Y cells incubated with Abeta and CEHA was 28% higher than that with Abeta and the mixture of EHA and CHA. These results clearly indicate the synergism of the two inhibitors. It is considered that the difference in the hydrophobicities of the two inhibitors made the bi-modification of HA provide a favorable CEHA nanostructure that coordinated different inhibition effects of the two inhibitors. This research indicates that fabrication of dual-inhibitor nanosystem is promising for the development of potent agents against Abeta aggregation and cytotoxicity. PMID- 29472607 TI - Cell transplantation and clinical reality: Kuwait experience in persons with spinal cord injury. AB - STUDY DESIGN: Retrospective observational. OBJECTIVES: To compare objective (neurological examination) and subjective (patients perception) recovery in patients with spinal cord injury (SCI) who chose to undergo cell transplantation therapies (CTT) outside of clinical trials abroad. SETTING: Physical Medicine and Rehabilitation Hospital, Kuwait. METHODS: Nine patients with SCI who had undergone CTT outside Kuwait were identified and their neurological pre transplantation evaluation according the International Standards for Neurological Classification of SCI (ISNCSCI) was collected from hospital records. Post transplantation ISNCSCI examination was conducted during follow-up visits and scores were completed between pre and post CTT. In addition to the ISNCSCI evaluation, change in disability status, and patient's perception of improvement after stem cell transplantation were examined. RESULTS: Overall, 8 males and 1 female with chronic SCI underwent CTT (42 +/- 38.2 months post SCI) in various centers (China, Egypt, Germany, India, and Iran). On follow-up post CTT assessment (89.2 +/- 36 months post SCI), 55.5% of individuals reported perceived improvement as follows: increased deep tissue sensation below the injury (100%) or increase in bladder sensation (11.1%). Objective examination after CTT revealed that none of the examined individuals demonstrated improvement in their motor scores or neurological level of SCI. CONCLUSION: We were not able to objectively document clinically useful improvements in sensorimotor, autonomic, or functional status in individuals after CTT. PMID- 29472608 TI - Cognitive performance of people with traumatic spinal cord injury: a cross sectional study comparing people with subacute and chronic injuries. AB - STUDY DESIGN: Cross-sectional study. OBJECTIVES: To assess the impact of spinal cord injury (SCI) on cognitive function in individuals with subacute and chronic SCI. SETTING: National Hospital for SCI patients (Spain). METHODS: The present investigation was designed to determine the nature, pattern, and extent of cognitive deficits in a group of participants with subacute (n = 32) and chronic (n = 34) SCI, using a comprehensive battery of reliable and validated neuropsychological assessments to study a broad range of cognitive functions. Twenty-seven able-bodied subjects matched to the groups with SCI for age and educational level formed the control group. RESULTS: The neuropsychological assessment showed alterations in the domain of attention, processing speed, memory and learning, executive functions, and in recognition in participants with SCI. The prevalence of cognitive dysfunction in the chronic stage was also confirmed at the individual level. The comparison of the neuropsychological assessment between the groups with subacute and chronic SCI showed a worsening of cognitive functions in those with chronic SCI compared to the group with subacute SCI. CONCLUSIONS: In participants with SCI, cognitive dysfunctions are present in the subacute stage and worsen over time. From a clinical point of view, we confirmed the presence of cognitive dysfunction that may interfere with the first stage of rehabilitation which is the most intense and important. Moreover, cognitive dysfunction may be important beyond the end of the first stage of rehabilitation as it can affect an individual's quality of life and possible integration to society.

AB - The ability to maintain coherence and control in a qubit is a major requirement for quantum computation. We show theoretically that long coherence times can be achieved at easily accessible temperatures (such as boiling point of liquid helium) in small (i.e., ~10 nanometers) charge qubits of oxide double quantum dots when only optical phonons are the source of decoherence. In the regime of strong electron-phonon coupling and in the non-adiabatic region, we employ a duality transformation to make the problem tractable and analyze the dynamics through a non-Markovian quantum master equation. We find that the system decoheres after a long time, despite the fact that no energy is exchanged with the bath. Detuning the dots to a fraction of the optical phonon energy, increasing the electron-phonon coupling, reducing the adiabaticity, or decreasing the temperature enhances the coherence time.

AB - Parallel single-cell sequencing protocols represent powerful methods for investigating regulatory relationships, including epigenome-transcriptome interactions. Here, we report a single-cell method for parallel chromatin accessibility, DNA methylation and transcriptome profiling. scNMT-seq (single cell nucleosome, methylation and transcription sequencing) uses a GpC methyltransferase to label open chromatin followed by bisulfite and RNA sequencing. We validate scNMT-seq by applying it to differentiating mouse embryonic stem cells, finding links between all three molecular layers and revealing dynamic coupling between epigenomic layers during differentiation. PMID- 29472611 TI - Synthesis of armchair graphene nanoribbons from the 10,10'-dibromo-9,9' bianthracene molecules on Ag(111): the role of organometallic intermediates. AB - We investigate the bottom-up growth of N = 7 armchair graphene nanoribbons (7 AGNRs) from the 10,10'-dibromo-9,9'-bianthracene (DBBA) molecules on Ag(111) with the focus on the role of the organometallic (OM) intermediates. It is demonstrated that DBBA molecules on Ag(111) are partially debrominated at room temperature and lose all bromine atoms at elevated temperatures. Similar to DBBA on Cu(111), debrominated molecules form OM chains on Ag(111). Nevertheless, in contrast with the Cu(111) substrate, formation of polyanthracene chains from OM intermediates via an Ullmann-type reaction is feasible on Ag(111). Cleavage of C Ag bonds occurs before the thermal threshold for the surface-catalyzed activation of C-H bonds on Ag(111) is reached, while on Cu(111) activation of C-H bonds occurs in parallel with the cleavage of the stronger C-Cu bonds. Consequently, while OM intermediates obstruct the Ullmann reaction between DBBA molecules on the Cu(111) substrate, they are required for the formation of polyanthracene chains on Ag(111). If the Ullmann-type reaction on Ag(111) is inhibited, heating of the OM chains produces nanographenes instead. Heating of the polyanthracene chains produces 7-AGNRs, while heating of nanographenes causes the formation of the disordered structures with the possible admixture of short GNRs.

AB - Difficulties in 'theory of mind' (the ability to attribute mental states to oneself or others, and to make predictions about another's behaviour based on these attributions) have been observed in several psychiatric conditions. We investigate the genetic architecture of theory of mind in 4,577 13-year-olds who completed the Emotional Triangles Task (Triangles Task), a first-order test of theory of mind. We observe a small but significant female-advantage on the Triangles Task (Cohen's d = 0.19, P < 0.01), in keeping with previous work using other tests of theory of mind. Genome-wide association analyses did not identify any significant loci, and SNP heritability was non-significant. Polygenic scores for six psychiatric conditions (ADHD, anorexia, autism, bipolar disorder, depression, and schizophrenia), and empathy were not associated with scores on the Triangles Task. However, polygenic scores of cognitive aptitude, and cognitive empathy, a term synonymous with theory of mind and measured using the "Reading the Mind in the Eyes" Test, were significantly associated with scores on the Triangles Task at multiple P-value thresholds, suggesting shared genetics between different measures of theory of mind and cognition. PMID- 29472612 TI - Sumoylation regulates FMRP-mediated dendritic spine elimination and maturation. AB - Fragile X syndrome (FXS) is the most frequent inherited cause of intellectual disability and the best-studied monogenic cause of autism. FXS results from the functional absence of the fragile X mental retardation protein (FMRP) leading to abnormal pruning and consequently to synaptic communication defects. Here we show that FMRP is a substrate of the small ubiquitin-like modifier (SUMO) pathway in the brain and identify its active SUMO sites. We unravel the functional consequences of FMRP sumoylation in neurons by combining molecular replacement strategy, biochemical reconstitution assays with advanced live-cell imaging. We first demonstrate that FMRP sumoylation is promoted by activation of metabotropic glutamate receptors. We then show that this increase in sumoylation controls the homomerization of FMRP within dendritic mRNA granules which, in turn, regulates spine elimination and maturation. Altogether, our findings reveal the sumoylation of FMRP as a critical activity-dependent regulatory mechanism of FMRP-mediated neuronal function. PMID- 29472614 TI - Painting with light-powered bacteria. AB - Self-assembly is a promising route for micro- and nano-fabrication with potential to revolutionise many areas of technology, including personalised medicine. Here we demonstrate that external control of the swimming speed of microswimmers can be used to self assemble reconfigurable designer structures in situ. We implement such 'smart templated active self assembly' in a fluid environment by using spatially patterned light fields to control photon-powered strains of motile Escherichia coli bacteria. The physics and biology governing the sharpness and formation speed of patterns is investigated using a bespoke strain designed to respond quickly to changes in light intensity. Our protocol provides a distinct paradigm for self-assembly of structures on the 10 MUm to mm scale. PMID- 29472615 TI - The Effects of Housing Density on Social Interactions and Their Correlations with Serotonin in Rodents and Primates. AB - Population density has been suggested to affect social interactions of individuals, but the underlying neural mechanisms remain unclear. In contrast, neurotransmission of monoamines such as serotonin (5-HT) and dopamine (DA) has been demonstrated to play important roles in social behaviors. Here, we investigated whether housing density affected social interactions of rodents and non-human primates housed in groups, and its correlations with monoamines. Japanese macaques exhibited higher plasma 5-HT, but not DA, concentrations than rhesus macaques. Similarly, C57BL/6 mice exhibited higher plasma and brain tissue 5-HT concentrations than DBA2 mice. Under crowding, C57BL/6 mice and Japanese macaques exhibited more prominent social avoidance with mates than DBA2 mice and rhesus macaques, respectively. Although DBA2 mice and rhesus macaques in crowding exhibited elevated plasma stress hormones, such stress hormone elevations associated with crowding were absent in C57BL/6 mice and Japanese macaques. Administration of parachlorophenylalanine, which inhibits 5-HT synthesis, increased social interactions and stress hormones in C57BL/6 mice under crowding. These results suggest that, animals with hyperserotonemia may exhibit social avoidance as an adaptive behavioral strategy to mitigate stress associated with crowding environments, which may also be relevant to psychiatric disorder such as autism spectrum disorder. PMID- 29472616 TI - Mutant p53 cancers reprogram macrophages to tumor supporting macrophages via exosomal miR-1246. AB - TP53 mutants (mutp53) are involved in the pathogenesis of most human cancers. Specific mutp53 proteins gain oncogenic functions (GOFs) distinct from the tumor suppressor activity of the wild-type protein. Tumor-associated macrophages (TAMs), a hallmark of solid tumors, are typically correlated with poor prognosis. Here, we report a non-cell-autonomous mechanism, whereby human mutp53 cancer cells reprogram macrophages to a tumor supportive and anti-inflammatory state. The colon cancer cells harboring GOF mutp53 selectively shed miR-1246-enriched exosomes. Uptake of these exosomes by neighboring macrophages triggers their miR 1246-dependent reprogramming into a cancer-promoting state. Mutp53-reprogammed TAMs favor anti-inflammatory immunosuppression with increased activity of TGF beta. These findings, associated with poor survival in colon cancer patients, strongly support a microenvironmental GOF role for mutp53 in actively engaging the immune system to promote cancer progression and metastasis. PMID- 29472618 TI - HIF-1alpha hampers dendritic cell function and Th1 generation during chronic visceral leishmaniasis. AB - Inflammation, although responsible for controlling infection, is often associated with the pathogenesis of chronic diseases. Leishmania donovani, the causative agent of visceral leishmaniasis, induces a strong inflammatory response that leads to splenomegaly and ultimately immune suppression. Inflamed tissues are typically characterized by low levels of oxygen, a microenvironment that triggers the hypoxia-inducible transcription factor 1alpha (HIF-1alpha). Although HIF 1alpha plays an integral role in dendritic cell function, its involvement in the generation of protective Th1 responses against Leishmania has not yet been studied. Here we demonstrate that HIF-1alpha inhibits IL-12 production in dendritic cells, limiting therefore Th1 cell development. Indeed, depletion of HIF-1alpha in CD11c+ cells resulted in higher and sustained expression of IL-12 and complete abrogation of IL-10. Moreover, CD11c-specific HIF-1alpha-deficient mice showed higher frequencies of IFN-gamma-producing CD4 T cells in the spleen and bone marrow and, consequently, a significantly reduced parasite burden in both organs. Taken together, our results suggest that HIF-1alpha expression in dendritic cells largely contributes to the establishment of persistent Leishmania infection and may therefore represent a possible therapeutic target. PMID- 29472617 TI - Whole genome diversity of inherited chromosomally integrated HHV-6 derived from healthy individuals of diverse geographic origin. AB - Human herpesviruses 6-A and -B (HHV-6A, HHV-6B) are ubiquitous in human populations worldwide. These viruses have been associated with several diseases such as multiple sclerosis, Hodgkin's lymphoma or encephalitis. Despite of the need to understand the genetic diversity and geographic stratification of these viruses, the availability of complete viral sequences from different populations is still limited. Here, we present nine new inherited chromosomally integrated HHV-6 sequences from diverse geographical origin which were generated through target DNA enrichment on lymphoblastoid cell lines derived from healthy individuals. Integration with available HHV-6 sequences allowed the assessment of HHV-6A and -6B phylogeny, patterns of recombination and signatures of natural selection. Analysis of the intra-species variability showed differences between A and B diversity levels and revealed that the HHV-6B reference (Z29) is an uncommon sequence, suggesting the need for an alternative reference sequence. Signs of geographical variation are present and more defined in HHV-6A, while they appear partly masked by recombination in HHV-6B. Finally, we conducted a scan for signatures of selection in protein coding genes that yielded at least 6 genes (4 and 2 respectively for the A and B species) showing significant evidence for accelerated evolution, and 1 gene showing evidence of positive selection in HHV-6A. PMID- 29472619 TI - Modulating bacterial and gut mucosal interactions with engineered biofilm matrix proteins. AB - Extracellular appendages play a significant role in mediating communication between bacteria and their host. Curli fibers are a class of bacterial fimbria that is highly amenable to engineering. We demonstrate the use of engineered curli fibers to rationally program interactions between bacteria and components of the mucosal epithelium. Commensal E. coli strains were engineered to produce recombinant curli fibers fused to the trefoil family of human cytokines. Biofilms formed from these strains bound more mucins than those producing wild-type curli fibers, and modulated mucin rheology as well. When treated with bacteria producing the curli-trefoil fusions mammalian cells behaved identically in terms of their migration behavior as when they were treated with the corresponding soluble trefoil factors. Overall, this demonstrates the potential utility of curli fibers as a scaffold for the display of bioactive domains and an untapped approach to rationally modulating host-microbe interactions using bacterial matrix proteins. PMID- 29472620 TI - Repopulated microglia are solely derived from the proliferation of residual microglia after acute depletion. AB - Newborn microglia rapidly replenish the whole brain after selective elimination of most microglia (>99%) in adult mice. Previous studies reported that repopulated microglia were largely derived from microglial progenitor cells expressing nestin in the brain. However, the origin of these repopulated microglia has been hotly debated. In this study, we investigated the origin of repopulated microglia by a series of fate-mapping approaches. We first excluded the blood origin of repopulated microglia via parabiosis. With different transgenic mouse lines, we then demonstrated that all repopulated microglia were derived from the proliferation of the few surviving microglia (<1%). Despite a transient pattern of nestin expression in newly forming microglia, none of repopulated microglia were derived from nestin-positive non-microglial cells. In summary, we conclude that repopulated microglia are solely derived from residual microglia rather than de novo progenitors, suggesting the absence of microglial progenitor cells in the adult brain. PMID- 29472621 TI - Temporal trends of phthalate exposures during 2007-2010 in Swedish pregnant women. AB - BACKGROUND: The general population is exposed to phthalates, a group of chemicals with strong evidence for endocrine disrupting properties, commonly used in a large number of consumer products. Based on published research and evidence compiled by environmental agencies, certain phthalate applications and products have become restricted, leading to an increasing number of "new generation compounds" coming onto the market during recent years replacing older phthalates. Some examples of such newer compounds are di-iso-nonyl phthalate (DiNP), di-iso decyl phthalate (DiDP), and most recently di-isononyl-cyclohexane-1,2 dicarboxylate (DiNCH). OBJECTIVES: In order to evaluate temporal trends in phthalate exposure, first trimester urinary biomarkers of phthalates were measured in the Swedish SELMA study over a period of 2.5 years (2007-2010). METHODS: We collected first morning void urine samples around week 10 of pregnancy from 1651 pregnant women. Spot samples were analyzed for 13 phthalate metabolites and one phthalate replacement and least square geometric mean (LSGM) levels of the metabolites were compared between the sampling years when adjusted for potential confounders. RESULTS: All 14 metabolites were detectable in more than 99% of the SELMA subjects. The levels were generally comparable to other studies, but the SELMA subjects showed slightly higher exposure to butyl-benzyl phthalate (BBzP) and di-butyl phthalate (DBP). Di-ethyl-hexyl phthalate (DEHP) metabolites levels decreased while DiNP, DiDP/di-2-propylheptyl phthalate (DPHP), and DiNCH metabolites levels increased during the sampling period. CONCLUSIONS: Urinary metabolite levels of the older phthalates and more recently introduced phthalate replacement compound changed during the short sampling period in this Swedish pregnancy cohort. Our results indicate that replacement of phthalates can make an impact on human exposure to these chemicals. During this particularly vulnerable stage of life, phthalate exposures are of particular concern as the impacts, though not immediately noticeable, may increase the risk for health effects later in life. PMID- 29472622 TI - Aberrant methylated key genes of methyl group metabolism within the molecular etiology of urothelial carcinogenesis. AB - Urothelial carcinoma (UC), the most common cancer of the urinary bladder causes severe morbidity and mortality, e.g. about 40.000 deaths in the EU annually, and incurs considerable costs for the health system due to the need for prolonged treatments and long-term monitoring. Extensive aberrant DNA methylation is described to prevail in urothelial carcinoma and is thought to contribute to genetic instability, altered gene expression and tumor progression. However, it is unknown how this epigenetic alteration arises during carcinogenesis. Intact methyl group metabolism is required to ensure maintenance of cell-type specific methylomes and thereby genetic integrity and proper cellular function. Here, using two independent techniques for detecting DNA methylation, we observed DNA hypermethylation of the 5'-regulatory regions of the key methyl group metabolism genes ODC1, AHCY and MTHFR in early urothelial carcinoma. These hypermethylation events are associated with genome-wide DNA hypomethylation which is commonly associated with genetic instability. We therefore infer that hypermethylation of methyl group metabolism genes acts in a feed-forward cycle to promote additional DNA methylation changes and suggest a new hypothesis on the molecular etiology of urothelial carcinoma. PMID- 29472623 TI - Effectiveness and Safety of Different Rivaroxaban Dosage Regimens in Patients with Non-Valvular Atrial Fibrillation: A Nationwide, Population-Based Cohort Study. AB - The objective of this study is to evaluate the effectiveness of different rivaroxaban dosage regimens in preventing ischemic stroke and systemic thromboembolism among Asians. A retrospective cohort study was conducted on data from nationwide insurance claims in Taiwan. Patients with non-valvular atrial fibrillation under warfarin or rivaroxaban therapy were included. Propensity score matching was used to balance the covariates, and Cox-proportional hazard models were applied to compare the effectiveness and safety of each treatment group. Rivaroxaban was associated with a significantly lower risk of venous thromboembolism (hazard ratio [HR]: 0.51; 95% confidence interval [CI]: 0.29 0.92, P = 0.02) and intracranial hemorrhage (HR: 0.48; 95% CI: 0.32-0.72, P < 0.001) than warfarin. Rivaroxaban 20 mg and 15 mg were associated with a significantly lower risk of ischemic stroke (20 mg, HR: 0.48; CI: 0.29-0.80, P = 0.005; 15 mg, HR: 0.69; CI: 0.53-0.90, P = 0.005), but rivaroxaban 10 mg was not. In the subgroup analysis of patients older than 65 years, the results were generally the same, except that rivaroxaban had a significantly lower risk of ischemic stroke than warfarin. PMID- 29472624 TI - Citalopram inhibits platelet function independently of SERT-mediated 5-HT transport. AB - Citalopram prevents serotonin (5-HT) uptake into platelets by blocking the serotonin reuptake transporter (SERT). Although some clinical data suggest that selective serotonin reuptake inhibitors (SSRIs) may affect haemostasis and thrombosis, these poorly-characterised effects are not well understood mechanistically and useful in vitro data is limited. We sought to determine whether the inhibitory effects of citalopram on platelets are mediated via its pharmacological inhibition of 5-HT transport. We quantified the inhibitory potency of (RS)-, (R)- and (S)-citalopram on platelet function. If SERT blockade is the primary mechanism for citalopram-mediated platelet inhibition, these potencies should show quantitative congruence with inhibition of 5-HT uptake. Our data show that citalopram inhibits platelet aggregation, adhesion and thromboxane production with no difference in potency between (R)- and (S)-isomers. By contrast, citalopram had a eudysmic ratio of approximately 17 (S > R) for SERT blockade. Furthermore, nanomolar concentrations of citalopram inhibited 5-HT uptake into platelets but had no effect on other platelet functions, which were inhibited by micromolar concentrations. Our data indicate that citalopram-induced inhibition of platelets in vitro is not mediated by blockade of 5-HT transport. This raises a new question for future investigation: by what mechanism(s) does citalopram inhibit platelets? PMID- 29472626 TI - Nonlinear internal wave spirals in the northern East China Sea. AB - Oceanic internal waves are known to be important to the understanding of underwater acoustics, marine biogeochemistry, submarine navigation and engineering, and the Earth's climate. In spite of the importance and increased knowledge of their ubiquity, the wave generation is still poorly understood in most parts of the world's oceans. Here, we use satellite synthetic aperture radar images, in-situ observations, and numerical models to (1) show that wave energy (having relatively high amplitude) radiates from a shallow sill in the East China Sea in all directions, but with a significant time lag dependent on background conditions, (2) reveal that wave fronts are locally formed with often favorable conditions for re-initiation, and (3) demonstrate the resulting variety of wave patterns. These findings would be the case for any broad shelf having shallow sills with time-varying conditions, and therefore have significant implications on the redistribution of energy and materials in the global as well as regional ocean. PMID- 29472625 TI - The role of medial prefrontal cortex in the working memory maintenance of one's own emotional responses. AB - The role of medial prefrontal cortex (MPFC) in maintaining emotional information within working memory (WM) remains insufficiently investigated - with some studies suggesting this process activates MPFC and others suggesting its activity is suppressed. To reconcile these different results, we asked 26 healthy participants to complete a WM task involving the maintenance of emotional content (EWM), visual content (VWM), or no content ("rest") after exposure to emotion provoking images. We also assessed individual differences in emotional awareness (EA). We observed that dorsal MPFC was more active during EWM than VWM; further, relative to the rest condition, both of these WM conditions involved suppression of ventral MPFC. We also observed that the dorsal anterior cingulate subregion of dorsal MPFC was positively associated with EA. We discuss how these results may be able to reconcile the findings of previous EWM studies, and extend understanding of the relationship between MPFC, EA, and WM. PMID- 29472627 TI - Quantum phase transitions in highly crystalline two-dimensional superconductors. AB - Superconductor-insulator transition is one of the remarkable phenomena driven by quantum fluctuation in two-dimensional (2D) systems. Such a quantum phase transition (QPT) was investigated predominantly on highly disordered thin films with amorphous or granular structures using scaling law with constant exponents. Here, we provide a totally different view of QPT in highly crystalline 2D superconductors. According to the magneto-transport measurements in 2D superconducting ZrNCl and MoS2, we found that the quantum metallic state commonly observed at low magnetic fields is converted via the quantum Griffiths state to the weakly localized metal at high magnetic fields. The scaling behavior, characterized by the diverging dynamical critical exponent (Griffiths singularity), indicates that the quantum fluctuation manifests itself as superconducting puddles, in marked contrast to the thermal fluctuation. We suggest that an evolution from the quantum metallic to the quantum Griffiths state is generic nature in highly crystalline 2D superconductors with weak pinning potentials. PMID- 29472628 TI - Ultrastructural and Immunohistochemical Features of Telocytes in Placental Villi in Preeclampsia. AB - A new cell type, interstitial Cajal-like cell (ICLC), was recently described in different organs. The name was recently changed to telocytes (TCs), and their typical thin, long processes have been named telopodes (Tp). TCs regulate the contractile activity of smooth muscle cells and play a role in regulating vessel contractions. Although the placenta is not an innervated organ, we believe that TCs are present in the placenta. We studied placenta samples from physiological pregnancies and in different variants of preeclampsia (PE). We examined these samples using light microscopy of semi-thin sections, transmission electron microscopy, and immunohistochemistry. Immunohistochemical examination was performed with primary antibodies to CD34, CD117, SMA, and vimentin, and TMEM16a (DOG-1), the latter was used for the diagnosis of gastrointestinal stromal tumours (GIST) consisting of TCs. We have identified a heterogenetic population of TSs in term placentas, as these cell types differed in their localization, immunophenotype and ultrastructural characteristics. We assume TMEM16a could be used as the marker for identification of TCs. In PE we have revealed telocyte like cells with ultrastructural signs of fibrocytes (significant process thickening and the granular endoplasmic reticulum content was increased) and a loss of TMEM16a immunohistochemical staining. PMID- 29472629 TI - Indication to pelvic lymph nodes dissection for prostate cancer: the role of multiparametric magnetic resonance imaging when the risk of lymph nodes invasion according to Briganti updated nomogram is <5. AB - BACKGROUND: The Briganti updated nomogram (BN) is the most popular predictive model aiming to predict the presence of lymph node invasion (LNI) in patients with prostate cancer (PCa), but it lacks information obtained by preoperative imaging. The primary aim of the study was to evaluate the role of multiparametric prostate magnetic resonance imaging (mp-MRI) in the indication to perform pelvic lymph nodes dissection (PLND) or not in patients with risk of LNI according to BN below 5%. METHODS: Since March 2012 and September 2016, 310 patients who underwent a preoperative mp-MRI for staging purpose and subsequent robot-assisted extended PLND (RAEPLND) were retrospectively evaluated. Mp-MRIs were prospectively analyzed by two experienced radiologists. The imaging parameters analyzed were the presence of extracapsular extension (ECE), seminal vesicles invasion (SVI) and predominant Gleason pattern 4 (pG4). All patients underwent RAEPLND by two experienced surgeons with a standardized technique. A dedicated uropathologist performed all pathological analysis. Univariate analysis and multivariate logistic regression analysis were used in order to identify the predictors of LNI in patients with PCa. RESULTS: In the overall population, 57 (18.4%) patients had histologically proven pN1 disease. 48/250 patients (19.2%) with a risk of LNI >=5% as calculated by the BN were staged pN1 at final histopathological analysis. 9/60 patients (15.0%) with a risk of LNI <5% as calculated by BN, who underwent RAEPLND anyway according to the findings at mp MRI, were staged pN1 at final histopathological analysis. At multivariate logistic regression analysis, all the three mp-MRI parameters were significant independent predictors of LNI after RAEPLND. CONCLUSIONS: The role of mp-MRI seemed to be crucial in patients with a risk of LNI <5% as calculated by the BN. The presence of ECE, SVI, or pG4 at mp-MRI was found to be an independent predictor of LNI by itself. PMID- 29472630 TI - Spin-helix Larmor mode. AB - A two-dimensional electron gas (2DEG) with equal-strength Rashba and Dresselhaus spin-orbit coupling sustains persistent helical spin-wave states, which have remarkably long lifetimes. In the presence of an in-plane magnetic field, there exist single-particle excitations that have the character of propagating helical spin waves. For magnon-like collective excitations, the spin-helix texture reemerges as a robust feature, giving rise to a decoupling of spin-orbit and electronic many-body effects. We prove that the resulting spin-flip wave dispersion is the same as in a magnetized 2DEG without spin-orbit coupling, apart from a shift by the spin-helix wave vector. The precessional mode about the persistent spin-helix state is shown to have an energy given by the bare Zeeman splitting, in analogy with Larmor's theorem. We also discuss ways to observe the spin-helix Larmor mode experimentally. PMID- 29472631 TI - Enhanced efficiency of crystalline Si solar cells based on kerfless-thin wafers with nanohole arrays. AB - Several techniques have been proposed for kerfless wafering of thin Si wafers, which is one of the most essential techniques for reducing Si material loss in conventional wafering methods to lower cell cost. Proton induced exfoliation is one of promising kerfless techniques due to the simplicity of the process of implantation and cleaving. However, for application to high efficiency solar cells, it is necessary to cope with some problems such as implantation damage removal and texturing of (111) oriented wafers. This study analyzes the end-of range defects at both kerfless and donor wafers and ion cutting sites. Thermal treatment and isotropic etching processes allow nearly complete removal of implantation damages in the cleaved-thin wafers. Combining laser interference lithography and a reactive ion etch process, a facile nanoscale texturing process for the kerfless thin wafers of a (111) crystal orientation has been developed. We demonstrate that the introduction of nanohole array textures with an optimal design and complete damage removal lead to an improved efficiency of 15.2% based on the kerfless wafer of a 48 MUm thickness using the standard architecture of the Al back surface field. PMID- 29472632 TI - African swine fever virus encodes for an E2-ubiquitin conjugating enzyme that is mono- and di-ubiquitinated and required for viral replication cycle. AB - African swine fever virus is the etiological agent of a contagious and fatal acute haemorrhagic viral disease for which there are no vaccines or therapeutic options. The ASFV encodes for a putative E2 ubiquitin conjugating enzyme (ORF I215L) that shows sequence homology with eukaryotic counterparts. In the present study, we showed that pI215L acts as an E2-ubiquitin like enzyme in a large range of pH values and temperatures, after short incubation times. Further experiments revealed that pI215L is polyubiquitinated instead of multi-mono-ubiquitinated and Cys85 residue plays an essential role in the transthioesterification reaction. In infected cells, I215L gene is transcribed from 2 hours post infection and immunoblot analysis confirmed that pI215L is expressed from 4 hpi. Immunofluorescence studies revealed that pI215L is recruited to viral factories from 8 hpi and a diffuse distribution pattern throughout the nucleus and cytoplasm. siRNA studies suggested that pI215L plays a critical role in the transcription of late viral genes and viral DNA replication. Altogether, our results emphasize the potential use of this enzyme as target for drug and vaccine development against ASF.

PMID- 29472634 TI - Hakai overexpression effectively induces tumour progression and metastasis in vivo. AB - At early stages of carcinoma progression, epithelial cells undergo a program named epithelial-to-mesenchymal transition characterized by the loss of the major component of the adherens junctions, E-cadherin, which in consequence causes the disruption of cell-cell contacts. Hakai is an E3 ubiquitin-ligase that binds to E cadherin in a phosphorylated-dependent manner and induces its degradation; thus modulating cell adhesions. Here, we show that Hakai expression is gradually increased in adenoma and in different TNM stages (I-IV) from colon adenocarcinomas compared to human colon healthy tissues. Moreover, we confirm that Hakai overexpression in epithelial cells drives transformation in cells, a mesenchymal and invasive phenotype, accompanied by the downregulation of E cadherin and the upregulation of N-cadherin, and an increased proliferation and an oncogenic potential. More importantly, for the first time, we have studied the role of Hakai during cancer progression in vivo. We show that Hakai-transformed MDCK cells dramatically induce tumour growth and local invasion in nude mice and tumour cells exhibit a mesenchymal phenotype. Furthermore, we have detected the presence of micrometastasis in the lung mice, further confirming Hakai role during tumour metastasis in vivo. These results lead to the consideration of Hakai as a potential new therapeutic target to block tumour development and metastasis. PMID- 29472635 TI - Nasopharyngeal Pneumococcal Carriage in Nigeria: a two-site, population-based survey. AB - Changes in nasopharyngeal (NP) carriage of vaccine-type (VT) Streptococcus pneumoniae can be used to assess the effectiveness of a pneumococcal conjugate vaccine (PCV10). We conducted a baseline carriage survey in rural (Kumbotso, Kano) and urban (Pakoto, Ogun) Nigeria. In this cross-sectional study, we obtained data on demography, clinical history, risk factors, and took NP swabs for pneumococcal culture. We calculated crude and age-standardised carriage prevalence and used log-binomial regression to assess risk factors for carriage. Among children aged <5 years, 92% (95% CI: 88-95%) and 78% (73-82%), respectively, carried any pneumococcus and 48% and 50%, respectively, carried PCV10 serotypes. In Kumbotso, carriage prevalence was >40% across all ages. The age-standardized prevalence of pneumococcal carriage was 66% in Kumbotso and 40% in Pakoto. The most commonly identified serotypes were 19 F, 6 A and 23 F. Risk factors for carriage were young age, recent rhinorrhoea, cohabitation with >=2 children aged <5 years, and sharing a bed with >=2 persons. Pneumococcal carriage prevalence is high in this Nigerian population. Persisting prevalence of VT carriage in older children and adults suggests that PCV10 introduction in children will not eliminate transmission of vaccine serotypes rapidly. High vaccine coverage will therefore be required to ensure full protection of children.

The TGFbeta/TGFbetaR and CXCL12/CXCR4 axes induce myofibroblast phenoconversion independently through Smads and MEK/Erk proteins, respectively. To investigate these mechanisms at the genetic level, we have now elucidated the TGFbeta/TGFbetaR and CXCL12/CXCR4 transcriptomes in human fibroblasts. These transcriptomes are largely convergent, and up-regulate transcripts encoding proteins known to promote myofibroblast phenoconversion. These studies also revealed a molecular signature unique to CXCL12/CXCR4 axis activation for COPII vesicle formation, ubiquitination, and Golgi/ER localization/targeting. In particular, both CUL3 and KLHL12, key members of the Cullin-RING (CRL) ubiquitin ligase family of proteins involved in procollagen transport from the ER to the Golgi, were highly up-regulated in CXCL12-, but repressed in TGFbeta-, treated cells. Up-regulation of CUL3 and KLHL12 was correlated with higher procollagen secretion by CXCL12-treated cells, and this affect was ablated upon treatment with inhibitors specific for CXCR4 or CUL3 and repressed by TGFbeta/TGFbetaR axis activation. The results of these studies show that activation of the CXCL12/CXCR4 axis uniquely facilitates procollagen I secretion through a COPII-vesicle mediated mechanism to promote production of the ECM characteristic of fibrosis.

PMID- 29472639 TI - Transcription Factor Target Gene Network governs the Logical Abstraction Analysis of the Synthetic Circuit in Leishmaniasis. AB - With the advent of synthetic biology in medicine many synthetic or engineered proteins have made their way to therapeutics and diagnostics. In this paper, the downstream gene network of CD14-TNF-EGFR pathway in leishmaniasis, a tropical disease, is reconstructed. Network analysis showed that NFkB links the signaling and gene network, used as a point of intervention through a synthetic circuit embedded within the negative autoregulatory feedback loop. A chimeric protein kinase C (PKC) is incorporated in the synthetic circuit, under the transcriptional regulation of Lac repressor and IPTG, as an inducer. The chimeric PKC_zetaalpha via IkappaKb phosphorylation activates NFkappaB, and modulates the gene expression from an anti-inflammatory to a pro-inflammatory phenotype in in vitro L. major infected macrophage model. This is the first ever report of a synthetic device construction in leishmania. PMID- 29472640 TI - Ubc9 overexpression and SUMO1 deficiency blunt inflammation after intestinal ischemia/reperfusion. AB - The intestinal epithelium constitutes a crucial defense to the potentially life threatening effects of gut microbiota. However, due to a complex underlying vasculature, hypoperfusion and resultant tissue ischemia pose a particular risk to function and integrity of the epithelium. The small ubiquitin-like modifier (SUMO) conjugation pathway critically regulates adaptive responses to metabolic stress and is of particular significance in the gut, as inducible knockout of the SUMO-conjugating enzyme Ubc9 results in rapid intestinal epithelial disintegration. Here we analyzed the pattern of individual SUMO isoforms in intestinal epithelium and investigated their roles in intestinal ischemia/reperfusion (I/R) damage. Immunostaining revealed that epithelial SUMO2/3 expression was almost exclusively limited to crypt epithelial nuclei in unchallenged mice. However, intestinal I/R or overexpression of Ubc9 caused a remarkable enhancement of epithelial SUMO2/3 staining along the crypt-villus axis. Unexpectedly, a similar pattern was found in SUMO1 knockout mice. Ubc9 transgenic mice, but also SUMO1 knockout mice were protected from I/R injury as evidenced by better preserved barrier function and blunted inflammatory responses. PCR array analysis of microdissected villus-tip epithelia revealed a specific epithelial contribution to reduced inflammatory responses in Ubc9 transgenic mice, as key chemotactic signaling molecules such as IL17A were significantly downregulated. Together, our data indicate a critical role particularly of the SUMO2/3 isoforms in modulating responses to I/R and provide the first evidence that SUMO1 deletion activates a compensatory process that protects from ischemic damage. PMID- 29472638 TI - Unexplored therapeutic opportunities in the human genome. AB - A large proportion of biomedical research and the development of therapeutics is focused on a small fraction of the human genome. In a strategic effort to map the knowledge gaps around proteins encoded by the human genome and to promote the exploration of currently understudied, but potentially druggable, proteins, the US National Institutes of Health launched the Illuminating the Druggable Genome (IDG) initiative in 2014. In this article, we discuss how the systematic collection and processing of a wide array of genomic, proteomic, chemical and disease-related resource data by the IDG Knowledge Management Center have enabled the development of evidence-based criteria for tracking the target development level (TDL) of human proteins, which indicates a substantial knowledge deficit for approximately one out of three proteins in the human proteome. We then present spotlights on the TDL categories as well as key drug target classes, including G protein-coupled receptors, protein kinases and ion channels, which illustrate the nature of the unexplored opportunities for biomedical research and therapeutic development. PMID- 29472641 TI - BigR is a sulfide sensor that regulates a sulfur transferase/dioxygenase required for aerobic respiration of plant bacteria under sulfide stress. AB - To cope with toxic levels of H2S, the plant pathogens Xylella fastidiosa and Agrobacterium tumefaciens employ the bigR operon to oxidize H2S into sulfite. The bigR operon is regulated by the transcriptional repressor BigR and it encodes a bifunctional sulfur transferase (ST) and sulfur dioxygenase (SDO) enzyme, Blh, required for H2S oxidation and bacterial growth under hypoxia. However, how Blh operates to enhance bacterial survival under hypoxia and how BigR is deactivated to derepress operon transcription is unknown. Here, we show that the ST and SDO activities of Blh are in vitro coupled and necessary to oxidize sulfide into sulfite, and that Blh is critical to maintain the oxygen flux during A. tumefaciens respiration when oxygen becomes limited to cells. We also show that H2S and polysulfides inactivate BigR leading to operon transcription. Moreover, we show that sulfite, which is produced by Blh in the ST and SDO reactions, is toxic to Citrus sinensis and that X. fastidiosa-infected plants accumulate sulfite and higher transcript levels of sulfite detoxification enzymes, suggesting that they are under sulfite stress. These results indicate that BigR acts as a sulfide sensor in the H2S oxidation mechanism that allows pathogens to colonize plant tissues where oxygen is a limiting factor. PMID- 29472642 TI - Role of trace amine-associated receptor 1 in nicotine's behavioral and neurochemical effects. AB - Nicotine addiction and abuse remains a global health issue. To date, the fundamental neurobiological mechanism of nicotine addiction remains incompletely understood. Trace amine-associated receptor 1 (TAAR1) is thought to directly modulate dopaminergic system and are thought to be a neural substrate underlying addictive-like behaviors. We aimed to investigate the role of TAAR1 in nicotine addictive-like behaviors. TAAR1 expression after nicotine treatment was evaluated by western blotting. c-Fos immunofluorescence and in vivo fast-scan cyclic voltammetry were used to examine the activation of brain regions and dopamine release, respectively. We then thoroughly and systematically examined the role of TAAR1 in mediating nicotine-induced sensitization, nicotine discrimination, nicotine self-administration, nicotine demand curve, and the reinstatement of nicotine-seeking. Local pharmacological manipulation was conducted to determine the role of TAAR1 in the nucleus accumbens (NAcs) in the reinstatement of nicotine-seeking. We found that the expression of TAAR1 protein was selectively downregulated in the NAc, with no change in either dorsal striatum or prefrontal cortex. TAAR1 activation was sufficient to block nicotine-induced c-Fos expression in the NAc, while also reducing nicotine-induced dopamine release in the NAc. Systemic administration of TAAR1 agonists attenuated the expression and development of nicotine-induced sensitization, nicotine self-administration, the reinstatement of nicotine-seeking, and increased the elasticity of nicotine demand curve, while intra-NAc infusions of a TAAR1 agonist was sufficient to attenuate nicotine reinstatement. Moreover, TAAR1-knockout rats showed augmented cue-induced and drug-induced reinstatement of nicotine-seeking. These results indicated that modulation of TAAR1 activity regulates nicotine addictive-like behaviors and TAAR1 represents a novel target towards the treatment of nicotine addiction. PMID- 29472643 TI - Behavioral and neural markers of cigarette-craving regulation in young-adult smokers during abstinence and after smoking. AB - Cigarette craving contributes substantially to the maintenance of tobacco use disorder. Behavioral strategies to regulate craving may facilitate smoking cessation but remain underexplored. We adapted an emotion-regulation strategy, using proximal/distal self-positioning, to the context of cigarette craving to examine craving regulation in 42, daily smokers (18-25 years old). After overnight abstinence from smoking, before and after smoking their first cigarette of the day, participants viewed videos of natural scenes presenting young adults who were either smoking cigarettes ("smoke") or not ("non-smoke"). Before each video, participants were instructed to imagine themselves either immersed in the scene ("close") or distanced from it ("far"). They rated their craving after each video. Task-based fMRI data are presented for a subsample of participants (N = 21). We found main effects of smoking, instruction, and video type on craving lower ratings after smoking than before, following the "far" vs. "close" instructions, and when viewing non-smoke vs. smoke videos. Before smoking, "smoke" vs. "non-smoke" videos elicited activation in, orbitofrontal cortex, anterior cingulate, lateral parietal cortex, mid-occipital cortex, ventral striatum, dorsal caudate, and midbrain. Smoking reduced activation in anterior cingulate, left inferior frontal gyrus, and bilateral temporal poles. Activation was reduced in the ventral striatum and medial prefrontal cortex after the "far" vs. the "close" instruction, suggesting less engagement with the stimuli during distancing. The results indicate that proximal/distal regulation strategies impact cue-elicited craving, potentially via downregulation of the ventral striatum and medial prefrontal cortex, and that smoking during abstinence may increase cognitive control capacity during craving regulation. PMID- 29472645 TI - A single, extinction-based treatment with a kappa opioid receptor agonist elicits a long-term reduction in cocaine relapse. AB - Kappa opioid receptor (KOR) agonists have known anti-addiction properties and can reduce drug seeking. Their potential for clinical use has largely been daunted by their aversive properties mediated through p38 MAPK signaling. Here we examined the therapeutic potential of the KOR agonist U50,488 (U50) to reduce cocaine seeking in a self-administration model. Following cocaine self-administration and 7 days of forced home-cage abstinence, rats were administered a single dose of U50 (5 mg/kg, i.p.) 30 min prior to the first extinction training session, wherein cocaine and the discrete cocaine-paired cues were no longer available. U50 reduced cocaine seeking on this first extinction session, but did not alter extinction training over subsequent days. 2 weeks after U50 treatment, rats underwent a test of cue-induced reinstatement, and rats that had received U50 reinstated less than controls. Central inhibition of p38 MAPK at the time of U50 administration prevented its long-term therapeutic effect on reinstatement, but not its acute reduction in drug seeking on extinction day 1. The long-term therapeutic effect of U50 required operant extinction during U50 exposure, extended to cocaine-primed reinstatement, and was not mimicked by another aversive drug, lithium chloride (LiCl). These data suggest U50 elicits its long term anti-relapse effects through a KOR-p38 MAPK-specific aversive counterconditioning of the operant cocaine-seeking response. A single, albeit aversive treatment that is able to reduce relapse long-term warrants further consideration of the therapeutic potential of KOR agonists in the treatment of addiction. PMID- 29472644 TI - Effects of COMT genotype and tolcapone on lapses of sustained attention after sleep deprivation in healthy young men. AB - Tolcapone, a brain penetrant selective inhibitor of catechol-O-methyltransferase (COMT) devoid of psychostimulant properties, improves cognition and cortical information processing in rested volunteers, depending on the genotype of the functional Val158Met polymorphism of COMT. The impact of this common genetic variant on behavioral and neurophysiological markers of increased sleep need after sleep loss is controversial. Here we investigated the potential usefulness of tolcapone to mitigate consequences of sleep deprivation on lapses of sustained attention, and tested the hypothesis that dopamine signaling in the prefrontal cortex (PFC) causally contributes to neurobehavioral and neurophysiological markers of sleep homeostasis in humans. We first quantified in 73 young male volunteers the impact of COMT genotype on the evolution of attentional lapses during 40 h of extended wakefulness. Subsequently, we tested in an independent group of 30 young men whether selective inhibition of COMT activity with tolcapone counteracts attentional and neurophysiological markers of elevated sleep need in a genotype-dependent manner. Neither COMT genotype nor tolcapone affected brain electrical activity in wakefulness and sleep. By contrast, COMT genotype and tolcapone modulated the sleep loss-induced impairment of vigilant attention. More specifically, Val/Met heterozygotes produced twice as many lapses after a night without sleep than Met/Met homozygotes. Unexpectedly, tolcapone further deteriorated the sleep loss-induced performance deficits when compared to placebo, particularly in Val/Met and Met/Met genotypes. The findings suggest that PFC dopaminergic tone regulates sustained attention after sleep loss according to an inverse U-shape relationship, independently of neurophysiological markers of elevated sleep need.

PMID- 29472646 TI - Interaction between noradrenergic and cholinergic signaling in amygdala regulates anxiety- and depression-related behaviors in mice. AB - Medications that target the noradrenergic system are important therapeutics for depression and anxiety disorders. More recently, clinical studies have shown that the alpha2-noradrenergic receptor (alpha2AR) agonist guanfacine can decrease stress-induced smoking relapse during acute abstinence, suggesting that targeting the noradrenergic system may aid in smoking cessation through effects on stress pathways in the brain. Acetylcholine (ACh), like the nicotine in tobacco, acts at nicotinic acetylcholine receptors (nAChRs) to regulate behaviors related to anxiety and depression. We therefore investigated interactions between guanfacine and ACh signaling in tests of anxiolytic and antidepressant efficacy in female and male C57BL/6J mice, focusing on the amygdala as a potential site of noradrenergic/cholinergic interaction. The antidepressant-like effects of guanfacine were blocked by shRNA-mediated knockdown of alpha2AR in amygdala. Knockdown of the high-affinity beta2 nAChR subunit in amygdala also prevented antidepressant-like effects of guanfacine, suggesting that these behavioral effects require ACh signaling through beta2-containing nAChRs in this brain area. Ablation of NE terminals prevented the anxiolytic- and antidepressant-like effects of the nicotinic partial agonist cytisine, whereas administration of the cholinesterase antagonist physostigmine induced a depression-like phenotype that was not altered by knocking down alpha2AR in the amygdala. These studies suggest that ACh and NE have opposing actions on behaviors related to anxiety and depression and that cholinergic signaling through beta2-containing nAChRs and noradrenergic signaling through alpha2a receptors in neurons of the amygdala are critical for regulation of these behaviors.

AB - The rehabilitation of anterior dental aesthetics involves a multitude of disciplines, each with its own methodologies for achieving a predefined goal. The literature is awash with different techniques for a given predicament, based on both scientific credence, as well as empirical clinical judgements. An example is crown lengthening for correcting uneven gingival zeniths, increasing clinical crown lengths, and therefore, reducing the amount of maxillary gingival display that detracts from pleasing pink aesthetics. Many procedures have been advocated for rectifying gingival anomalies depending on prevailing clinical scenarios and aetiology. This paper presents a minimally invasive technique for crown lengthening for short clinical crowns concurrent with excessive maxillary gingival display, which is expedient, maintaining the inter-proximal papilla, mitigating morbidity, reducing post-operative inflammation, and increasing patient comfort. In addition, with a similar ethos, a minimally invasive tooth preparation approach is presented for achieving optimal white aesthetics. PMID- 29472663 TI - Dental careers: Good preparation.

AB - Background The ability of the dental profession to self-regulate and address poor performance or impairment is crucial if practitioners are to demonstrate a public commitment to patient safety. Failure of the profession to actively engage in this activity is likely to call into question trustworthiness and ability to place the interests of patients and the public first.Aim To investigate attitudes towards self-regulation and the raising of concerns as expressed through the ethical codes of different dental professional and regulatory organisations.Method A qualitative review of professional codes of ethics written and published by dental associations and regulatory bodies using thematic analysis to discern common attitudes and perspectives on self-regulation.Results Four main themes were identified; (1) explicit expression of the need to report; (2) warning against frivolous reporting; (3) acceptance of reporting being difficult and; (4) threshold requiring a professional to report. From these themes, common and differing attitudes were then explored.Conclusions This review shows that often codes of ethics and practice do discuss an obligation to self regulate and raise concerns but that this is accompanied by an anxiety surrounding unsubstantiated or malicious reporting. This gives the collective guidance a defensive tone and message that may be unhelpful in promoting a culture of openness and candour. PMID- 29472678 TI - OMFS: Resection of the calcified ligament.

The duration of its effects influences treatment intervals, cost and convenience to the patient. These are key factors in successful aesthetic procedures. A review of the literature found that duration of effect was between two and six months, with most experiencing loss of maximal contraction for three to four months. Treatments may last between three to four months, and occasionally up to six months. No specific definition of effectiveness/efficacy has been described and used to measure comparable end points. Additional research should help clarify the impact of brand, age, gender, ethnicity, repetition of treatment and zinc phytase supplementation. PMID- 29472688 TI - Regenerative endodontic therapy for managing immature non-vital teeth: a national survey of UK paediatric dental specialists and trainees. AB - Background Several guidelines have been published advocating the use of regenerative endodontic therapy (RET) in managing non-vital immature permanent teeth. It is unclear, however, how many UK paediatric dental specialists routinely use this technique and their opinion of its outcomes, and barriers to its use.Aim To assess the knowledge, experience and the opinion of UK based paediatric dental specialists/trainees (UKPDS/T) and practitioners working in the capacity of paediatric dental specialists on the use of RET.Design A cross sectional study using a 22-item questionnaire was developed using the Bristol Online Survey tool and circulated electronically to members of the British Society of Paediatric Dentistry between August and November 2016.Results Ninety eight UKPDS/T completed the survey. A quarter of respondents (N = 24, 24.5%) reported using RET. Reasons cited for not using RET included lack of: training (N = 48, 45%), materials (N = 28, 26%), evidence (N = 17, 16%) and suitable cases (N = 6, 6%). Different protocols in terms of disinfection, medicaments, scaffolds, and obturation material were identified.Conclusions This survey highlights a low uptake of RET by current UKPDS and trainees with several barriers identified. Deviations from the current RET guidelines were identified. Recommendations addressing the use of RET in light of the findings of this survey were made. PMID- 29472690 TI - Cisplatin Enhances Hepatitis B Virus Replication and PGC-1alpha Expression through Endoplasmic Reticulum Stress. AB - Chronic hepatitis B infection remains a serious public health issue worldwide. Hepatitis B virus (HBV) reactivation is commonly reported in patients receiving anticancer therapy, immunosuppressive therapy, or organ and tissue transplantation. However, the precise mechanisms underlying chemotherapeutic agent-related HBV reactivation remain unclear. Here, we report that peroxisome proliferator-activated receptor gamma coactivator 1 alpha (PGC-1alpha) plays a central role in cisplatin-induced HBV transcription and replication. First, cisplatin treatment upregulated the expression levels of PGC-1alpha and hepatocyte nuclear factor 4 alpha (HNF-4alpha) in both HBV-replicating cells and an HBV-transgenic mouse model. PGC-1alpha coactivates with HNF-4alpha, which interacts with a core promoter and enhancer II region of HBV genome, thereby promoting HBV production. In contrast, knockdown of PGC-1alpha and HNF-4alpha by RNA interference in hepatoma cells reversed HBV activation in response to cisplatin. Additionally, PGC-1alpha upregulation depended on cisplatin-mediated endoplasmic reticulum (ER) stress. We further observed that the recruitment of cyclic AMP-responsive element-binding protein plays a crucial role for PGC-1alpha transcriptional activation in cisplatin-treated cells. Finally, pharmacologic inhibition of ER stress impaired PGC-1alpha upregulation and HBV production induced by cisplatin treatment. These findings demonstrate novel molecular mechanisms indicating that ER stress-PGC1alpha signaling pathway plays a critical role in cisplatin-evoked HBV reactivation. PMID- 29472692 TI - Unbiased Spontaneous Solar Fuel Production using Stable LaFeO3 Photoelectrode. AB - Photoelectrochemical (PEC) water splitting to produce solar fuel (hydrogen) has long been considered as the Holy Grail to a carbon-free hydrogen economy. The PEC concept to produce solar fuel is to emulate the natural photosynthesis using man made materials. The bottle-neck in realising the concept practically has been the difficulty in identifying stable low-cost semiconductors that meet the thermodynamic and kinetic criteria for photoelectrolysis. We have fabricated a novel p-type LaFeO3 photoelectrode using an inexpensive and scalable spray pyrolysis method. Our nanostructured LaFeO3 photoelectrode results in spontaneous hydrogen evolution from water without any external bias applied. Moreover, the photoelectrode has a faradaic efficiency of 30% and showed excellent stability over 21 hours. From optical and impedance data, the constructed band diagram showed that LaFeO3 can straddle the water redox potential with the conduction band at -1.11 V above the reduction potential of hydrogen. We have fabricated a low cost LaFeO3 photoelectrode that can spontaneously produce hydrogen from water using sunlight, making it a strong future candidate for renewable hydrogen generation. PMID- 29472691 TI - A reappraisal of CTLA-4 checkpoint blockade in cancer immunotherapy. AB - It is assumed that anti-CTLA-4 antibodies cause tumor rejection by blocking negative signaling from B7-CTLA-4 interactions. Surprisingly, at concentrations considerably higher than plasma levels achieved by clinically effective dosing, the anti-CTLA-4 antibody Ipilimumab blocks neither B7 trans-endocytosis by CTLA-4 nor CTLA-4 binding to immobilized or cell-associated B7. Consequently, Ipilimumab does not increase B7 on dendritic cells (DCs) from either CTLA4 gene humanized (Ctla4 h/h ) or human CD34+ stem cell-reconstituted NSGTM mice. In Ctla4 h/m mice expressing both human and mouse CTLA4 genes, anti-CTLA-4 antibodies that bind to human but not mouse CTLA-4 efficiently induce Treg depletion and Fc receptor dependent tumor rejection. The blocking antibody L3D10 is comparable to the non blocking Ipilimumab in causing tumor rejection. Remarkably, L3D10 progenies that lose blocking activity during humanization remain fully competent in inducing Treg depletion and tumor rejection. Anti-B7 antibodies that effectively block CD4 T cell activation and de novo CD8 T cell priming in lymphoid organs do not negatively affect the immunotherapeutic effect of Ipilimumab. Thus, clinically effective anti-CTLA-4 mAb causes tumor rejection by mechanisms that are independent of checkpoint blockade but dependent on the host Fc receptor. Our data call for a reappraisal of the CTLA-4 checkpoint blockade hypothesis and provide new insights for the next generation of safe and effective anti-CTLA-4 mAbs. PMID- 29472693 TI - A new allele of the Brachytic2 gene in maize can efficiently modify plant architecture. AB - The applications of semi-dwarf genes such as sd1 and Rht1 in rice and wheat resulted in the first "green revolution" in the 1960s. However, such semi-dwarf genes that can efficiently reduce plant stature and have few negative yield traits have not yet been identified in maize. In this study, a new allele of Brachytic2 gene (qpa1) encoding P-glycoprotein was rapidly fine-mapped using a modified method. The qpa1, containing a 241-bp deletion in the last exon, had no negative effect on yield, but greatly modified the plant architecture including significantly reduced plant height and ear height, increased stalk diameter and erected leaf. A common variant similar to maize qpa1 was also present in the sorghum orthologous dw3 locus. Comparative RNA-seq analysis next showed 99 differentially co-expressed genes affected by Br2 in maize and dw3 in sorghum, including four plant height genes D3, BAK1, Actin7 and Csld1, which are involved in gibberellin and brassinosteroid biosynthesis, auxin transport and cellulose synthesis. The qpa1 can be applied to efficiently modify plant stature in maize and in combination with D3, BAK1, Actin7, Csld1 and the other 95 differentially co-expressed genes, can be edited using new genomic editing tools for further applications and studies. PMID- 29472694 TI - Improving accuracies of genomic predictions for drought tolerance in maize by joint modeling of additive and dominance effects in multi-environment trials. AB - Breeding for drought tolerance is a challenging task that requires costly, extensive, and precise phenotyping. Genomic selection (GS) can be used to maximize selection efficiency and the genetic gains in maize (Zea mays L.) breeding programs for drought tolerance. Here, we evaluated the accuracy of genomic selection (GS) using additive (A) and additive + dominance (AD) models to predict the performance of untested maize single-cross hybrids for drought tolerance in multi-environment trials. Phenotypic data of five drought tolerance traits were measured in 308 hybrids along eight trials under water-stressed (WS) and well-watered (WW) conditions over two years and two locations in Brazil. Hybrids' genotypes were inferred based on their parents' genotypes (inbred lines) using single-nucleotide polymorphism markers obtained via genotyping-by sequencing. GS analyses were performed using genomic best linear unbiased prediction by fitting a factor analytic (FA) multiplicative mixed model. Two cross-validation (CV) schemes were tested: CV1 and CV2. The FA framework allowed for investigating the stability of additive and dominance effects across environments, as well as the additive-by-environment and the dominance-by environment interactions, with interesting applications for parental and hybrid selection. Results showed differences in the predictive accuracy between A and AD models, using both CV1 and CV2, for the five traits in both water conditions. For grain yield (GY) under WS and using CV1, the AD model doubled the predictive accuracy in comparison to the A model. Through CV2, GS models benefit from borrowing information of correlated trials, resulting in an increase of 40% and 9% in the predictive accuracy of GY under WS for A and AD models, respectively. These results highlight the importance of multi-environment trial analyses using GS models that incorporate additive and dominance effects for genomic predictions of GY under drought in maize single-cross hybrids. PMID- 29472695 TI - Deficiency of a pyrroline-5-carboxylate reductase produces the yellowish green cocoon 'Ryokuken' of the silkworm, Bombyx mori. AB - The silkworm cocoon colour has attracted researchers involved in genetics, physiology and ecology for a long time. 'Ryokuken' cocoons are yellowish green in colour due to unusual flavonoids, prolinylflavonols, while 'Sasamayu' cocoons are light green and contain only simple flavonol glucosides. We found a novel gene associated with the cocoon colour change resulting from a change in flavonoid composition and named it Lg (light green cocoon). In the middle silk glands of the + Lg /+ Lg larvae, 1-pyrroline-5-carboxylic acid (P5C) was found to accumulate due to a decrease in the activity of pyrroline-5-carboxylate reductase (P5CR), an enzyme reducing P5C to proline. Sequence analysis of BmP5CR1, the candidate gene for Lg, revealed a 1.9 kb insertion and a 4 bp deletion within the 1st intron, a 97 bp deletion within the 4th intron, and a > 300 bp insertion within the 3'-UTR, in addition to two amino acid changes on exons 3 and 4 in + Lg /+ Lg compared to Lg/Lg. Decreased expression of BmP5CR1 was observed in all of the investigated tissues, including the middle silk glands in + Lg /+ Lg , which was probably caused by structural changes in the intronic regions of BmP5CR1. Furthermore, a BmP5CR1 knockout strain exhibited a yellowish green cocoon with the formation of prolinylflavonols. These results indicate that the yellowish green cocoon is produced by a BmP5CR1 deficiency. To our knowledge, this is the first report showing that the defect of an enzyme associated with intermediate metabolism promotes the conjugation of phytochemicals derived from foods with endogenously accumulating metabolites in animal tissues.

AB - Glaucoma is an optic neuropathy, specifically a neurodegenerative disease characterized by loss of retinal ganglion cells (RGCs) and their axons. The pathogenesis of RGC loss in glaucoma remains incompletely understood and a broad range of possible mechanisms have been implicated. Clinical evidence indicates that lowering intraocular pressure (IOP) does not prevent progression in all patients; therefore, risk factors other than those related to IOP are involved in the disease. The need for alternative, non-IOP-lowering treatments focused at preventing progression, that is, neuroprotectants, has become of interest to both the patient and the physician. Experimental evidence accumulated during the past two decades lend a great deal of support to molecules endowed with neuroprotective features. However, translation to the clinic of the latter drugs results unsuccessful mostly because of the lack of reliable in vivo measure of retinal damage, thus hampering the good therapeutic potential of neuroprotective agents given alone or as adjuvant therapy to IOP-lowering agents. Further research effort is needed to better understand the mechanisms involved in glaucoma and the means to translate into clinic neuroprotective drugs. PMID- 29472701 TI - Akkermansia muciniphila-derived extracellular vesicles influence gut permeability through the regulation of tight junctions. AB - The gut microbiota has an important role in the gut barrier, inflammation and metabolic functions. Studies have identified a close association between the intestinal barrier and metabolic diseases, including obesity and type 2 diabetes (T2D). Recently, Akkermansia muciniphila has been reported as a beneficial bacterium that reduces gut barrier disruption and insulin resistance. Here we evaluated the role of A. muciniphila-derived extracellular vesicles (AmEVs) in the regulation of gut permeability. We found that there are more AmEVs in the fecal samples of healthy controls compared with those of patients with T2D. In addition, AmEV administration enhanced tight junction function, reduced body weight gain and improved glucose tolerance in high-fat diet (HFD)-induced diabetic mice. To test the direct effect of AmEVs on human epithelial cells, cultured Caco-2 cells were treated with these vesicles. AmEVs decreased the gut permeability of lipopolysaccharide-treated Caco-2 cells, whereas Escherichia coli derived EVs had no significant effect. Interestingly, the expression of occludin was increased by AmEV treatment. Overall, these results imply that AmEVs may act as a functional moiety for controlling gut permeability and that the regulation of intestinal barrier integrity can improve metabolic functions in HFD-fed mice.

AB - To understand the regulation of Helicobacter pylori (H. pylori)-associated gastric carcinogenesis, we examined the effect of B-cell translocation gene 2 (BTG2) expression on the biological activity of Tipalpha, an oncoprotein secreted from H. pylori. BTG2, the human ortholog of mouse TIS21 (BTG2/TIS21), has been reported to be a primary response gene that is transiently expressed in response to various stimulations. Here, we report that BTG2 is constitutively expressed in the mucous epithelium and parietal cells of the gastric gland in the stomach. Expression was increased in the mucous epithelium following H. pylori infection in contrast to its loss in human gastric adenocarcinoma. Indeed, adenoviral transduction of BTG2/TIS21 significantly inhibited Tipalpha activity in MKN-1 and MGT-40, human and mouse gastric cancer cells, respectively, thereby downregulating tumor necrosis factor-alpha (TNFalpha) expression and Erk1/2 phosphorylation by reducing expression of nucleolin, a Tipalpha receptor. Chromatin immunoprecipitation proved that BTG2/TIS21 inhibited Sp1 expression and its binding to the promoter of the nucleolin gene. In addition, BTG2/TIS21 expression significantly reduced membrane-localized nucleolin expression in cancer cells, and the loss of BTG2/TIS21 expression induced cytoplasmic nucleolin availability in gastric cancer tissues, as evidenced by immunoblotting and immunohistochemistry. Higher expression of BTG2 and lower expression of nucleolin were accompanied with better overall survival of poorly differentiated gastric cancer patients. This is the first report showing that BTG2/TIS21 inhibits nucleolin expression via Sp1 binding, which might be associated with the inhibition of H. pylori-induced carcinogenesis. We suggest that BTG2/TIS21 is a potential inhibitor of nucleolin in the cytoplasm, leading to inhibition of carcinogenesis after H. pylori infection.

PMID- 29472703 TI - Suppression of the ERK-SRF axis facilitates somatic cell reprogramming. AB - The molecular mechanism underlying the initiation of somatic cell reprogramming into induced pluripotent stem cells (iPSCs) has not been well described. Thus, we generated single-cell-derived clones by using a combination of drug-inducible vectors encoding transcription factors (Oct4, Sox2, Klf4 and Myc) and a single cell expansion strategy. This system achieved a high reprogramming efficiency after metabolic and epigenetic remodeling. Functional analyses of the cloned cells revealed that extracellular signal-regulated kinase (ERK) signaling was downregulated at an early stage of reprogramming and that its inhibition was a driving force for iPSC formation. Among the reprogramming factors, Myc predominantly induced ERK suppression. ERK inhibition upregulated the conversion of somatic cells into iPSCs through concomitant suppression of serum response factor (SRF). Conversely, SRF activation suppressed the reprogramming induced by ERK inhibition and negatively regulated embryonic pluripotency by inducing differentiation via upregulation of immediate early genes, such as c-Jun, c-Fos and EGR1. These data reveal that suppression of the ERK-SRF axis is an initial molecular event that facilitates iPSC formation and may be a useful surrogate marker for cellular reprogramming. PMID- 29472707 TI - Concern for mortality in the neonatal intensive care unit (NICU): parent and physician perspectives. AB - OBJECTIVE: The objectives of this study are as follows: (1) to determine the incidence of parental concern for mortality (PCM) and any potential predictors for it among parents of infants admitted to the Neonatal Intensive Care Unit (NICU), and (2) to explore physicians' perspectives with respect to PCM in the NICU and to examine current practices of addressing it. STUDY DESIGN: Separate questionnaires were distributed to members of the AAP Section on Perinatal Neonatal Medicine District I and to NICU parents post discharge, to gather perspectives from each group. A chi2-analysis and linear regression were performed. RESULTS: Response rate was 29% for the physician survey and 63% for the parent survey. Physician respondents believed that PCM increased with decreasing gestational age (GA) and reported having fewer discussions with parents of older infants about PCM. Parental report of PCM incidence was 48% overall. PCM was not associated with GA. PCM was associated with infant length of stay and occurrence of at least one discussion about PCM with physicians. Fifty three percent of parents reported never having a discussion regarding PCM. CONCLUSION: Although physicians believe that PCM increases with decreasing GA, parental report suggests that PCM is not associated with GA. Parents of full-term infants in particular may experience more PCM and desire for discussion than is currently recognized. PMID- 29472706 TI - Atm reactivation reverses ataxia telangiectasia phenotypes in vivo. AB - Hereditary deficiencies in DNA damage signaling are invariably associated with cancer predisposition, immunodeficiency, radiation sensitivity, gonadal abnormalities, premature aging, and tissue degeneration. ATM kinase has been established as a central player in DNA double-strand break repair and its deficiency causes ataxia telangiectasia, a rare, multi-system disease with no cure. So ATM represents a highly attractive target for the development of novel types of gene therapy or transplantation strategies. Atm tamoxifen-inducible mouse models were generated to explore whether Atm reconstitution is able to restore Atm function in an Atm-deficient background. Body weight, immunodeficiency, spermatogenesis, and radioresistance were recovered in transgenic mice within 1 month from Atm induction. Notably, life span was doubled after Atm restoration, mice were protected from thymoma and no cerebellar defects were observed. Atm signaling was functional after DNA damage in vivo and in vitro. In summary, we propose a new Atm mouse model to investigate novel therapeutic strategies for ATM activation in ataxia telangiectasia disease. PMID- 29472708 TI - No question too small: development of a question prompt list for parents of critically ill infants. AB - OBJECTIVE: To develop a question prompt list tailored to the needs of parents of critically ill infants at risk of neurodevelopmental impairment. STUDY DESIGN: Question content was derived from audio-recorded neonatal intensive care unit family meetings and interviews with parents of infants treated with therapeutic hypothermia. Question content was refined using clinician focus groups. Acceptability testing was performed with parents and clinicians caring for infants in the neonatal intensive care unit. RESULTS: All clinicians and parents found the QPL content acceptable. Parents universally endorsed that the question prompt list was useful to them and would help them prepare for a meeting with their infant's healthcare team. CONCLUSION: This question prompt list, designed for parents of critically ill infants, is acceptable to parents and clinicians, and can be used in the acute neonatal course to facilitate parent engagement in family meetings. PMID- 29472709 TI - Splanchnic NIRS monitoring in neonatal care: rationale, current applications and future perspectives. AB - Near infrared spectroscopy (NIRS) provides a non-invasive, continuous monitoring of regional tissue oxygenation. NIRS assessment of neonatal splanchnic oxygenation (SrSO2) has gained increasing interest over the last decade, as local hypoxia and ischemia underlie the most feared gut complications in neonates. Current literature provides encouraging evidence in support of SrSO2 reliability in detecting mesenteric hemodynamic changes related to various physiological and pathological conditions in-term and preterm infants. Even so, while splanchnic NIRS monitoring looks promising for investigating gut physiopathology in research settings, further studies are needed to evaluate its feasibility as a routine monitoring tool in neonatal care and to investigate its potential role in clinical decision making. After a brief introduction to NIRS technical principles, this review aims to provide a complete overview of current neonatal applications for splanchnic NIRS monitoring, to discuss its possible limitations and to suggest future directions for research and clinical applications.

AB - It has been known for a long time that thyroid hormones have prominent effects on hepatic fatty acid and cholesterol synthesis and metabolism. Indeed, hypothyroidism has been associated with increased serum levels of triglycerides and cholesterol as well as non-alcoholic fatty liver disease (NAFLD). Advances in areas such as cell imaging, autophagy and metabolomics have generated a more detailed and comprehensive picture of thyroid-hormone-mediated regulation of hepatic lipid metabolism at the molecular level. In this Review, we describe and summarize the key features of direct thyroid hormone regulation of lipogenesis, fatty acid beta-oxidation, cholesterol synthesis and the reverse cholesterol transport pathway in normal and altered thyroid hormone states. Thyroid hormone mediates these effects at the transcriptional and post-translational levels and via autophagy. Given these potentially beneficial effects on lipid metabolism, it is possible that thyroid hormone analogues and/or mimetics might be useful for the treatment of metabolic diseases involving the liver, such as hypercholesterolaemia and NAFLD. PMID- 29472714 TI - Oncogene-induced senescence mediated by c-Myc requires USP10 dependent deubiquitination and stabilization of p14ARF. AB - Oncogene-induced senescence (OIS) is a critical tumor-suppressor mechanism, which prevents hyper-proliferation and transformation of cells. c-Myc promotes OIS through the transcriptional activation of p14ARF followed by p53 activation. Although the oncogene-mediated transcriptional regulation of p14ARF has been well addressed, the post-translational modification of p14ARF regulated by oncogenic stress has yet to be investigated. Here, we found that c-Myc increased p14ARF protein stability by inducing the transcription of ubiquitin-specific protease 10 (USP10). USP10, in turn, mediated the deubiquitination of p14ARF, preventing its proteasome-dependent degradation. USP10-null mouse embryonic fibroblasts and human primary cells depleted of USP10 bypassed c-Myc-induced senescence via the destabilization of p14ARF, and these cells displayed accelerated hyper proliferation and transformation. Clinically the c-Myc-USP10-p14ARF axis was disrupted in non-small cell lung cancer patients, resulting in significantly worse overall survival. Our studies indicate that USP10 induced by c-Myc has a crucial role in OIS by maintaining the stability of key tumor suppressor p14ARF. PMID- 29472715 TI - DeSUMOylation switches Kaiso from activator to repressor upon hyperosmotic stress. AB - Kaiso is a member of the BTB/POZ zinc finger family, which is involved in cancer progression, cell cycle control, apoptosis, and WNT signaling. Depending on promoter context, it may function as either a transcriptional repressor or activator. Previous studies found that Kaiso might be SUMOylated due to heat shock, but the biological significance of Kaiso SUMOylation is unclear. Here, we find that K42 is the only amino acid within Kaiso that is modified with SUMO. Kaiso is monoSUMOylated at lysine 42 in cell lines of kidney origin under normal physiological conditions. SUMOylated Kaiso can activate transcription from exogenous methylated promoters, wherein the deSUMOylated form of the protein kept the ability to be a repressor. Rapid Kaiso deSUMOylation occurs in response to hyperosmotic stress and is reversible upon return to an isotonic environment. DeSUMOylation occurs within minutes in HEK293 cells treated with 100 mM NaCl and relaxes in 3 h even in a salt-containing medium. Genomic editing of Kaiso by conversion of K42 into R42 (K42R) in HEK293 cells that resulted in fully deSUMOylated endogenous protein led to misregulation of genes associated with ion transport, blood pressure, and the immune response. TRIM25 was significantly repressed in two K42R HEK293 clones. By a series of rescue experiments with K42R and KO HEK293 cells, we show that TRIM25 is a direct transcriptional target for Kaiso. In the absence of Kaiso, the level of TRIM25 is insensitive to hyperosmotic stress. Extending our observations to animal models, we show that in response to a high salt diet, Kaiso knockout mice are characterized by significantly higher blood pressure increases when compared to wild-type animals. Thus, we propose a novel biological role for Kaiso in the regulation of homeostasis. PMID- 29472716 TI - PD-1 is required to maintain stem cell properties in human dental pulp stem cells. AB - Programmed cell death-1 (PD-1) belongs to an inhibitory signaling pathway capable of maintaining central and peripheral immune tolerance. Blockage of PD-1 has been identified as a promising immunotherapeutic approach for cancer and chronic infectious diseases. However, it is unknown whether PD-1 pathway regulates stem cell function. It is generally believed that mesenchymal stem cells (MSCs) produce PD-1 ligand, but fail to express PD-1. In this study, we show that neural crest-derived MSCs from dental pulp (MSC-DP), but not MSCs from bone marrow, expressed PD-1. Knocking down PD-1 expression in MSC-DP results in a significantly reduced capacity for cell proliferation and accelerated multipotential differentiation. Mechanistically, we show that PD-1 regulates a SHP2/ERK/Notch cascade to maintain proliferation and a SHP2/ERK/beta-catenin cascade to inhibit osteo-/odontogenic differentiation. This study indicates that PD-1 is a key surface molecule controlling cell proliferation and multipotential differentiation of MSC-DP. Through regulating PD-1/SHP2/ERK signaling, we can significantly improve the quality and quantity of culture-expanded MSC-DP for potential clinical therapies. PMID- 29472717 TI - Revised cytogenetic risk stratification in primary myelofibrosis: analysis based on 1002 informative patients. AB - Current cytogenetic risk stratification in primary myelofibrosis (PMF) is two tiered: 'favorable' and 'unfavorable'. Recent studies have suggested prognostic heterogeneity within the unfavorable risk category. In 1002 consecutive patients, we performed stepwise analysis of impact on survival from individual and prognostically ordered cytogenetic abnormalities, leading to a revised three tiered risk model: 'very high risk (VHR)'-single/multiple abnormalities of -7, i(17q), inv(3)/3q21, 12p-/12p11.2, 11q-/11q23, or other autosomal trisomies not including + 8/ + 9 (e.g., +21, +19); 'favorable'-normal karyotype or sole abnormalities of 13q-, +9, 20q-, chromosome 1 translocation/duplication or sex chromosome abnormality including -Y; 'unfavorable'-all other abnormalities. Median survivals for VHR (n = 75), unfavorable (n = 190) and favorable (n = 737) risk categories were 1.2 (HR 3.8, 95% CI 2.9-4.9), 2.9 (HR 1.7, 95% CI 1.4-2.0) and 4.4 years and survival impact was independent of clinically derived prognostic systems, driver and ASXL1/SRSF2 mutations. The revised model was also effective in predicting leukemic transformation: HRs (95% CI) were 4.4 (2.0-9.4) for VHR and 2.0 (1.2-3.4) for unfavorable. The impact of driver mutations on survival was confined to favorable and that of ASXL1/SRSF2 mutations to favorable/unfavorable cytogenetic risk categories. The current study clarifies the prognostic hierarchy of genetic risk factors in PMF and provides a more refined three-tiered cytogenetic risk model. PMID- 29472719 TI - Epigenetic heterogeneity affects the risk of relapse in children with t(8;21)RUNX1-RUNX1T1-rearranged AML. AB - The somatic translocation t(8;21)(q22;q22)/RUNX1-RUNX1T1 is one of the most frequent rearrangements found in children with standard-risk acute myeloid leukemia (AML). Despite the favorable prognostic role of this aberration, we recently observed a higher than expected frequency of relapse. Here, we employed an integrated high-throughput approach aimed at identifying new biological features predicting relapse among 34 t(8;21)-rearranged patients. We found that the DNA methylation status of patients who suffered from relapse was peculiarly different from that of children maintaining complete remission. The epigenetic signature, made up of 337 differentially methylated regions, was then integrated with gene and protein expression profiles, leading to a network, where cell-to cell adhesion and cell-motility pathways were found to be aberrantly activated in relapsed patients. We identified most of these factors as RUNX1-RUNX1T1 targets, with Ras Homolog Family Member (RHOB) overexpression being the core of this network. We documented how RHOB re-organized the actin cytoskeleton through its downstream ROCK-LIMK-COFILIN axis: this increases blast adhesion by stress fiber formation, and reduces mitochondrial apoptotic cell death after chemotherapy treatment. Altogether, our data show an epigenetic heterogeneity within t(8;21) rearranged AML patients at diagnosis able to influence the program of the chimeric transcript, promoting blast re-emergence and progression to relapse. PMID- 29472718 TI - Pharmacologic inhibition of STAT5 in acute myeloid leukemia. AB - The transcription factor STAT5 is an essential downstream mediator of many tyrosine kinases (TKs), particularly in hematopoietic cancers. STAT5 is activated by FLT3-ITD, which is a constitutively active TK driving the pathogenesis of acute myeloid leukemia (AML). Since STAT5 is a critical mediator of diverse malignant properties of AML cells, direct targeting of STAT5 is of significant clinical value. Here, we describe the development and preclinical evaluation of a novel, potent STAT5 SH2 domain inhibitor, AC-4-130, which can efficiently block pathological levels of STAT5 activity in AML. AC-4-130 directly binds to STAT5 and disrupts STAT5 activation, dimerization, nuclear translocation, and STAT5 dependent gene transcription. Notably, AC-4-130 substantially impaired the proliferation and clonogenic growth of human AML cell lines and primary FLT3-ITD+ AML patient cells in vitro and in vivo. Furthermore, AC-4-130 synergistically increased the cytotoxicity of the JAK1/2 inhibitor Ruxolitinib and the p300/pCAF inhibitor Garcinol. Overall, the synergistic effects of AC-4-130 with TK inhibitors (TKIs) as well as emerging treatment strategies provide new therapeutic opportunities for leukemia and potentially other cancers. PMID- 29472720 TI - CAR T-cells targeting FLT3 have potent activity against FLT3-ITD+ AML and act synergistically with the FLT3-inhibitor crenolanib. AB - FMS-like tyrosine kinase 3 (FLT3) is a transmembrane protein expressed on normal hematopoietic stem and progenitor cells (HSC) and retained on malignant blasts in acute myeloid leukemia (AML). We engineered CD8+ and CD4+ T-cells expressing a FLT3-specific chimeric antigen receptor (CAR) and demonstrate they confer potent reactivity against AML cell lines and primary AML blasts that express either wild type FLT3 or FLT3 with internal tandem duplication (FLT3-ITD). We also show that treatment with the FLT3-inhibitor crenolanib leads to increased surface expression of FLT3 specifically on FLT3-ITD+ AML cells and consecutively, enhanced recognition by FLT3-CAR T-cells in vitro and in vivo. As anticipated, we found that FLT3-CAR T-cells recognize normal HSCs in vitro and in vivo, and disrupt normal hematopoiesis in colony-formation assays, suggesting that adoptive therapy with FLT3-CAR T-cells will require subsequent CAR T-cell depletion and allogeneic HSC transplantation to reconstitute the hematopoietic system. Collectively, our data establish FLT3 as a novel CAR target in AML with particular relevance in high-risk FLT3-ITD+ AML. Further, our data provide the first proof-of-concept that CAR T-cell immunotherapy and small molecule inhibition can be used synergistically, as exemplified by our data showing superior antileukemia efficacy of FLT3-CAR T-cells in combination with crenolanib. PMID- 29472722 TI - Chromothripsis in acute myeloid leukemia: biological features and impact on survival. AB - Chromothripsis is a one-step genome-shattering catastrophe resulting from disruption of one or few chromosomes in multiple fragments and consequent random rejoining and repair. This study defines incidence of chromothripsis in 395 newly diagnosed adult acute myeloid leukemia (AML) patients from three institutions, its impact on survival and its genomic background. SNP 6.0 or CytoscanHD Array (Affymetrix(r)) were performed on all samples. We detected chromothripsis with a custom algorithm in 26/395 patients. Patients harboring chromothripsis had higher age (p = 0.002), ELN high risk (HR) (p < 0.001), lower white blood cell (WBC) count (p = 0.040), TP53 loss, and/or mutations (p < 0.001) while FLT3 (p = 0.025), and NPM1 (p = 0.032) mutations were mutually exclusive with chromothripsis. Chromothripsis-positive patients showed a worse overall survival (OS) (p < 0.001) compared with HR patients (p = 0.011) and a poor prognosis in a COX-HR optimal regression model. Chromothripsis presented the hallmarks of chromosome instability [i.e., TP53 alteration, 5q deletion, higher mean of copy number alteration (CNA), complex karyotype, alterations in DNA repair, and cell cycle] and focal deletions on chromosomes 4, 7, 12, 16, and 17. CBA. FISH showed that chromothripsis is associated with marker, derivative, and ring chromosomes. In conclusion, chromothripsis frequently occurs in AML (6.6%) and influences patient prognosis and disease biology. PMID- 29472723 TI - Flow-cytometric vs. -morphologic assessment of remission in childhood acute lymphoblastic leukemia: a report from the Children's Oncology Group (COG). AB - Minimal residual disease (MRD) after initial therapy is integral to risk stratification in B-precursor and T-precursor acute lymphoblastic leukemia (B ALL, T-ALL). Although MRD determines depth of remission, remission remains defined by morphology. We determined the outcomes of children with discordant assessments of remission by morphology vs. flow cytometry using patients age 1 30.99 years enrolled on Children's Oncology Group ALL trials who underwent bone marrow assessment at the end of induction (N = 9350). Morphologic response was assessed locally as M1 (<5% lymphoblasts; remission), M2 (5-25%), or M3 (>25%). MRD was centrally measured by flow cytometry. Overall, 19.8% of patients with M2/M3 morphology had MRD < 5%. M1 with MRD >= 5% was less common in B-ALL (0.9%) than T-ALL (6.9%; p < 0.0001). In B-ALL, M1/MRD >= 5% was associated with superior 5-year event-free survival (EFS) than M2/MRD >= 5% (59.1% +/- 6.5% vs. 39.1% +/- 7.9%; p = 0.009), but was inferior to M1/MRD < 5% (87.1% +/- 0.4%; p < 0.0001). MRD levels were higher in M2/MRD >= 5% than M1/MRD >= 5% patients. In T ALL, EFS was not significantly different between M1/MRD >= 5% and M2/MRD >= 5%. Patients with morphologic remission but MRD >= 5% have outcomes similar to those who fail to achieve morphological remission, and significantly inferior to those with M1 marrows and concordant MRD, suggesting that flow cytometry should augment the definition of remission in ALL. PMID- 29472724 TI - Persistence of pre-leukemic clones during first remission and risk of relapse in acute myeloid leukemia. AB - Some patients with acute myeloid leukemia (AML) who are in complete remission after induction chemotherapy harbor persisting pre-leukemic clones, carrying a subset of leukemia-associated somatic mutations. There is conflicting evidence on the prognostic relevance of these clones for AML relapse. Here, we characterized paired pre-treatment and remission samples from 126 AML patients for mutations in 68 leukemia-associated genes. Fifty patients (40%) retained >=1 mutation during remission at a VAF of >=2%. Mutation persistence was most frequent in DNMT3A (65% of patients with mutations at diagnosis), SRSF2 (64%), TET2 (55%), and ASXL1 (46%), and significantly associated with older age (p < 0.0001) and, in multivariate analyses adjusting for age, genetic risk, and allogeneic transplantation, with inferior relapse-free survival (hazard ratio (HR), 2.34; p = 0.0039) and overall survival (HR, 2.14; p = 0.036). Patients with persisting mutations had a higher cumulative incidence of relapse before, but not after allogeneic stem cell transplantation. Our work underlines the relevance of mutation persistence during first remission as a novel risk factor in AML. Persistence of pre-leukemic clones may contribute to the inferior outcome of elderly AML patients. Allogeneic transplantation abrogated the increased relapse risk associated with persisting pre-leukemic clones, suggesting that mutation persistence may guide post-remission treatment. PMID- 29472725 TI - An ancient family of lytic polysaccharide monooxygenases with roles in arthropod development and biomass digestion. AB - Thermobia domestica belongs to an ancient group of insects and has a remarkable ability to digest crystalline cellulose without microbial assistance. By investigating the digestive proteome of Thermobia, we have identified over 20 members of an uncharacterized family of lytic polysaccharide monooxygenases (LPMOs). We show that this LPMO family spans across several clades of the Tree of Life, is of ancient origin, and was recruited by early arthropods with possible roles in remodeling endogenous chitin scaffolds during development and metamorphosis. Based on our in-depth characterization of Thermobia's LPMOs, we propose that diversification of these enzymes toward cellulose digestion might have endowed ancestral insects with an effective biochemical apparatus for biomass degradation, allowing the early colonization of land during the Paleozoic Era. The vital role of LPMOs in modern agricultural pests and disease vectors offers new opportunities to help tackle global challenges in food security and the control of infectious diseases. PMID- 29472726 TI - Combinatory use of distinct single-cell RNA-seq analytical platforms reveals the heterogeneous transcriptome response. AB - Single-cell RNA-seq is a powerful tool for revealing heterogeneity in cancer cells. However, each of the current single-cell RNA-seq platforms has inherent advantages and disadvantages. Here, we show that combining the different single cell RNA-seq platforms can be an effective approach to obtaining complete information about expression differences and a sufficient cellular population to understand transcriptional heterogeneity in cancers. We demonstrate that it is possible to estimate missing expression information. We further demonstrate that even in the cases where precise information for an individual gene cannot be inferred, the activity of given transcriptional modules can be analyzed. Interestingly, we found that two distinct transcriptional modules, one associated with the Aurora kinase gene and the other with the DUSP gene, are aberrantly regulated in a minor population of cells and may thus contribute to the possible emergence of dormancy or eventual drug resistance within the population. PMID- 29472727 TI - Nondestructive in-line sub-picomolar detection of magnetic nanoparticles in flowing complex fluids. AB - Over the last decades, the use of magnetic nanoparticles in research and commercial applications has increased dramatically. However, direct detection of trace quantities remains a challenge in terms of equipment cost, operating conditions and data acquisition times, especially in flowing conditions within complex media. Here we present the in-line, non-destructive detection of magnetic nanoparticles using high performance atomic magnetometers at ambient conditions in flowing media. We achieve sub-picomolar sensitivities measuring ~30 nm ferromagnetic iron and cobalt nanoparticles that are suitable for biomedical and industrial applications, under flowing conditions in water and whole blood. Additionally, we demonstrate real-time surveillance of the magnetic separation of nanoparticles from water and whole blood. Overall our system has the merit of in line direct measurement of trace quantities of ferromagnetic nanoparticles with so far unreached sensitivities and could be applied in the biomedical field (diagnostics and therapeutics) but also in the industrial sector.

AB - Objectives: The widespread use of camera surveillance in public places offers criminologists the opportunity to systematically and unobtrusively observe crime, their main subject matter. The purpose of this essay is to inform the reader of current developments in research on crimes caught on camera. Methods: We address the importance of direct observation of behavior and review criminological studies that used observational methods, with and without cameras, including the ones published in this issue. We also discuss the uses of camera recordings in other social sciences and in biology. Results: We formulate six key insights that emerge from the literature and make recommendations for future research. Conclusions: Camera recordings of real-life crime are likely to become part of the criminological tool kit that will help us better understand the situational and interactional elements of crime. Like any source, it has limitations that are best addressed by triangulation with other sources.

AB - Hydrophilic and hydrophobic weak polybasic brushes immersed in aqueous solutions of mixed salt counterions are considered using a mean-field numerical self consistent field approach. On top of the solvent quality of the polymer, the counterion-solvent interactions are accounted for by implementing Flory-Huggins interaction parameters. We show that ion specificity within the brush can bring about large changes in conformation. It is found that the collapse transition of hydrophobic, weak polyelectrolyte brushes features an intermediate two-phase state wherein a subset of chains are collapsed in a dense layer at the substrate, while the remainder of chains are well-solvated and strongly stretched away from the it. Besides pH and ionic strength, solvent quality of counterions and the composition of ions in the solvent are important control parameters for the behavior of polyelectrolyte brushes. Increasingly hydrophobic counterions penetrate deeper within the brush and stabilize the collapsed region, while hydrophilic counterions do the opposite. PMID- 29472731 TI - Investigating the role of alexithymia on the empathic deficits found in schizotypy and autism spectrum traits. AB - Alexithymia, the inability to identify and describe one's emotional experience, is elevated in many clinical populations, and related to poor interpersonal functioning. Alexithymia is also associated with empathic deficits in individuals with autism spectrum disorders. Accordingly, a better understanding of alexithymia could elucidate the nature of social-cognitive deficits transdiagnostically. We investigated alexithymia and components of empathy in relation to schizotypal and autism spectrum traits in healthy college students. Specifically, we examined higher-order components of empathic processing that involve perspective taking and other-oriented concern, which are reduced in alexithymia. Higher-order empathic processing was inversely correlated with both schizotypal and autism spectrum traits. Bootstrapping techniques revealed that alexithymia had a significant indirect effect on the relationship between higher order empathy and these personality traits; thus, alexithymia contributes uniquely to their relationship. These findings suggest alexithymia represents one possible mechanism for the development of empathic deficits in these populations. These results are consistent with the perspective that awareness of one's own emotional state may predicate a successful empathic response to another's. This work highlights the importance of a consideration of alexithymia in elucidating the nature of empathic deficits in various clinical populations, and points to a potential point of social intervention. PMID- 29472732 TI - Is the technical performance of young soccer players influenced by hormonal status, sexual maturity, anthropometric profile, and physical performance? AB - The aim of this study was to examine the influence of hormonal status, anthropometric profile, sexual maturity level, and physical performance on the technical abilities of 40 young male soccer players during small-sided games (SSGs). Anthropometric profiling, saliva sampling, sexual maturity assessment (Tanner scale), and physical performance tests (Yo-Yo and vertical jumps) were conducted two weeks prior to the SSGs. Salivary testosterone was determined by the enzyme-linked immunosorbent assay method. Technical performance was determined by the frequency of actions during SSGs. Principal component analyses identified four technical actions of importance: total number of passes, effectiveness, goal attempts, and total tackles. A multivariate canonical correlation analysis was then employed to verify the prediction of a multiple dependent variables set (composed of four technical actions) from an independent set of variables, composed of testosterone concentration, stage of pubic hair and genitalia development, vertical jumps and Yo-Yo performance. A moderate-to-large relationship between the technical performance set and the independent set was observed. The canonical correlation was 0.75 with a canonical R2 of 0.45. The highest structure coefficient in the technical performance set was observed for tackles (0.77), while testosterone presented the highest structure coefficient (0.75) for the variables of the independent set. The current data suggest that the selected independent set of variables might be useful in predicting SSG performance in young soccer players. Coaches should be aware that physical development plays a key role in technical performance to avoid decision-making mistakes during the selection of young players. PMID- 29472733 TI - Androgen interacts with exercise through the mTOR pathway to induce skeletal muscle hypertrophy. AB - This study was designed to investigate the effects of exogenous androgen and resistance exercise on skeletal muscle hypertrophy and the role of the mammalian target of rapamycin (mTOR) signalling during the process. A total of 24 male Sprague-Dawley rats were randomly assigned to sham operation and dihydrotestosterone (DHT) implantation groups with subgroups subjected to sedentary conditions or resistance exercise (SHAM+SED, SHAM+EX, DHT+SED, and DHT+EX). The experimental procedure lasted for 10 days. The mRNA expression of androgen receptor (AR) and insulin-like growth factor I (IGF-I), the expression of myosin heavy chain (MHC), as well as the phosphorylation statuses of AR, mTOR, p70 ribosomal S6 kinase (p70S6K), and eukaryotic translation initiation factor 4E binding protein 1 (4EBP1) were determined in the white gastrocnemius muscle. The cross sectional area and wet mass of the muscle were also measured. The cross sectional area and MHC expression were significantly higher in SHAM+EX, DHT+SED, and DHT+EX than in SHAM+SED. There was no significant difference among groups in muscle mass. The mRNA expression of AR and IGF-I and the phosphorylation of mTOR, p70S6K, and 4EBP1 were significantly increased in DHT+SED and SHAM+EX and were significantly enhanced in DHT+EX compared with either DHT or exercise alone. These data show that DHT causes hypertrophy in skeletal muscle and that exercise has a synergistic effect on DHT-induced hypertrophy. Exercise enhances androgen induced rapid anabolic action, which involves activation of the mTOR pathway. PMID- 29472734 TI - A meta-analysis of the association of CKM gene rs8111989 polymorphism with sport performance. AB - The muscle-specific creatine kinase (CKM) A/G variants (rs8111989) have been associated with skeletal muscle performance in humans; they are correlated with physical performance and contribute to differences in the maximum oxygen uptake (VO2max) responses during power or endurance training. However, there is not enough definitive evidence to demonstrate whether the A and G allelic variants of the CKM gene rs8111989 are indeed genetic factors that can influence human physical performance. In our study, we identified 9 articles on CKM in a literature search, and conducted two meta-analyses on the CKM rs8111989 A/G allele or genotype differences between power or endurance athletes and general controls. We found that the power athletes had a significantly higher frequency of the G allele (OR, 1.14; 95% CI, 1.02-1.28, P=0.03) and GG genotype (OR, 1.54; 95% CI, 1.24-1.91, P<0.0001) compared to controls, but there was no significant difference for the endurance athletes (G allele, OR, 0.95, 95%CI, 0.85-1.06, P=0.34; GG genotype, OR, 1.00, 95%CI, 0.78-1.27, P=1.00). The results provide additional evidence to support the notion that human physical performance might be influenced by genetic profiles, especially in power sports. PMID- 29472735 TI - Expression analysis of selected classes of circulating exosomal miRNAs in soccer players as an indicator of adaptation to physical activity. AB - Recently studies have shown that, depending on the type of training and its duration, the expression levels of selected circulating myomiRNAs (c-miR-27a,b, c miR-29a,b,c, c-miR-133a) differ and correlate with the physiological indicators of adaptation to physical activity. To analyse the expression of selected classes of miRNAs in soccer players during different periods of their training cycle. The study involved 22 soccer players aged 17-18 years. The multi-stage 20-m shuttle run test was used to estimate VO2 max among the soccer players. Samples serum were collected at baseline (time point I), after one week (time point II), and after 2 months of training (time point III). The analysis of the relative quantification (RQ) level of three exosomal myomiRNAs, c-miRNA-27b, c-miR-29a, and c-miR-133, was performed by quantitative polymerase chain reaction (qPCR) at three time points - before the training, after 1 week of training and after the completion of two months of competition season training. The expression analysis showed low expression levels (according to references) of all evaluated myomiRNAs before the training cycle. Analysis performed after a week of the training cycle and after completion of the entire training cycle showed elevated expression of all tested myomiRNAs. Statistical analysis revealed significant differences between the first and the second time point in soccer players for c-miR-27b and c miR-29a; between the first and the third time point for c-miR-27b and c-miR-29a; and between the second and the third time point for c-miR-27b. Statistical analysis showed a positive correlation between the levels of c-miR-29a and VO2 max. Two months of training affected the expression of c-miR-27b and miR-29a in soccer players. The increased expression of c-miR-27b and c-miR-29 with training could indicate their probable role in the adaptation process that takes place in the muscular system. Possibly, the expression of c-miR-29a will be found to be involved in cardiorespiratory fitness in future research. PMID- 29472736 TI - Variations in leptin, nesfatin-1 and irisin levels induced by aerobic exercise in young trained and untrained male subjects. AB - The aims of this study were to investigate the impacts of acute aerobic exercise on circulating levels of hormones associated with energy metabolism, namely leptin, nesfatin-1 and irisin, in trained and untrained male subjects and to determine whether the timing of the exercise (i.e. morning or night) amplified these impacts. Thirty trained (19.2+/-0.7 years) and 30 untrained (19.5+/-0.6 years) male subjects performed two aerobic running exercises (3 days between tests) to 64-76% of the subjects' maximal heart rate for about 30 min. Pre- and post-exercise venous blood samples were taken and analysed for leptin, nesfatin-1 and irisin using enzyme-linked immunosorbent assay (ELISA). Paired samples and independent samples t-tests were used to analyse data. Irisin levels increased in all the subjects (p<0.001). In both groups, nesfatin-1 levels increased significantly after the night-time exercise (p<0.05). Importantly, leptin and nesfatin-1 levels varied among the trained and untrained groups: Both leptin and nesfatin-1 levels increased in 4 (13%) and 12 (40%) subjects, respectively, after the morning exercises, and they increased in 9 (30%) and 10 (33%) subjects, respectively, after the night-time exercise. They decreased in 5 (16%) and 7 (23%) subjects, respectively, after the morning exercise and in 6 (20%) and 3 (10%) subjects, respectively, after the night-time exercise. Exercise may result in increased energy consumption by altering irisin levels. However, due to variations among individuals, increasing leptin and nesfatin-1 levels by reducing food intake may not be applicable. PMID- 29472737 TI - Associations of serum leptin, ghrelin and peptide YY levels with physical activity and cardiorespiratory fitness in adolescent boys with different BMI values. AB - : The aim of this study was to investigate the differences in associations of serum acylated and des-acylated ghrelin, peptide YY (PYY) and leptin levels with physical activity (PA) and cardiorespiratory fitness (CReF) in adolescent boys (mean age of 14.0 years) with overweight (OWB; n=55) and with normal weight (NWB; n=154). METHODS: Total PA was measured by 7-day accelerometry (counts/min) and CReF by peak oxygen consumption (VO2peak/kg). RESULTS: No differences were found in serum PYY, acylated ghrelin or des-acyl ghrelin levels, whereas mean leptin (11.6+/-10.6 vs. 2.0+/-2.7 ng/ml; p<0.05) and insulin (18.1+/-8.7 vs. 11.0+/-6.2 mU/l; p<0.05) levels were significantly higher in OWB compared to NWB. Mean CReF was significantly lower in OWB compared to NWB (39.7+/-8.7 vs. 50.5+/-6.8 ml/min/kg; p<0.05). Leptin was negatively correlated with CReF in both groups (r= 0.43; p<0.05), des-acylated ghrelin with CReF only in OWB (r =-0.36; p<0.05). In OWB leptin was negatively correlated with total PA (r=-0.32; p<0.05) and positively with sedentary time of PA (r=0.35; p<0.05). In NWB 28.1% of the variability of CReF was determined by leptin and insulin resistance index (HOMA IR), whereas in OWB 71.9% was determined by trunk FM and BMI. CONCLUSIONS: Leptin concentration was inversely associated with CReF in adolescent boys independently of BMI in both groups, while des-acylated ghrelin was associated with CReF only in OWB. Low PA in OWB was associated with high serum leptin level. PMID- 29472738 TI - Taurine supplementation improves economy of movement in the cycle test independently of the detrimental effects of ethanol. AB - Taurine (TA) ingestion has been touted as blunting the deleterious effects of ethanol (ET) ingestion on motor performance. This study investigated the effects of ingestion of 0.6 mL.kg-1 of ET, 6 grams of TA, and ethanol in combination with taurine (ET+TA) on economy of movement (EM) and heart rate (HR). Nine volunteers, five female (22 +/- 3 years) and four male (26 +/- 5 years), participated in a study that used a counterbalanced experimental design. EM and HR were measured for 6 min while the subjects were pedalling at a fixed load 10% below the anaerobic threshold. The blood alcohol concentration (BAC) was similar between ET and ET+TA treatments at 30 min after ingestion and after exercise (12.3 mmol.L-1 vs. 13.7 mmol.L-1, and 9.7 mmol * L-1 vs 10.9 mmol.L-1, respectively). EM was significantly different among treatments, with lower mL.W-1 following ingestion of TA (-7.1%, p<0.001) than placebo and ET+TA (-2.45%, p=0.001) compared to ET. HR (bpm) was significantly (p<0.05) higher for ET (137 +/- 14 bpm) than the other three treatments (placebo = 129 +/- 14 bpm; TA = 127 +/- 11 bpm; TA+ET = 133 +/- 12 and ET = 137 +/- 14 bpm). Taurine improved EM when compared to placebo or ET, and reduced HR when compared to ET. The combination of ET+TA also enhanced EM compared to placebo, and reduced HR in comparison to ET alone. Therefore, these findings indicate that taurine improves EM and counteracts ethanol-induced increases in HR during submaximal exercise. PMID- 29472739 TI - Longitudinal effects of swimming on bone in adolescents: a pQCT and DXA study. AB - The aims of the present study were, firstly, to evaluate areal bone mineral density (aBMD), bone strength and structure during a swimming season and compare them to those of normo-active controls (CG), and secondly to ascertain whether practising an additional weight-bearing sport other than swimming might improve bone. Twenty-three swimmers who only swam (SWI-PURE; 14 males, 9 females), 11 swimmers who combined swimming with an additional weight-bearing sport (SWI SPORT; 8 males, 3 females) and 28 controls (CG; 16 males, 12 females) participated in the present study. aBMD was assessed with dual energy X-ray (DXA). Bone mass, area, structure and strength of the non-dominant tibia and radius were measured with peripheral quantitative computed tomography (pQCT). Measurements were performed at the beginning of the swimming season and 8 months later. The only difference among groups for DXA and pQCT variables was found for arm aBMD, which was higher in the SWI-SPORT than in the CG group at both pre- and post-evaluation. Group by time interactions (GxT) were found for trochanter aBMD when comparing SWI-SPORT to CG and SWI-SPORT to SWI-PURE, favouring in both cases SWI-SPORT. No GxT were found for the radius. For the tibia, GxT were found between SWI-SPORT and CG and between SWI-PURE and CG, in both cases favouring the swimmers. A season of swimming does not confer any additional benefits to aBMD, but may confer minor benefits to structure and mass. Complementing swimming with a weight-bearing activity is beneficial to bone. PMID- 29472740 TI - Physiological and performance changes in national and international judo athletes during block periodization training. AB - Block periodization (BP) has been proposed as an alternative approach for application in the context of high-level sports. Despite its growing acceptance, there is no empirical evidence of BP adoption in high-level judo athletes. Therefore, this study aimed to compare the maximal strength, muscle power, judo specific performances, and hormonal concentration changes of state/national level (NG) and international level (IG) judo athletes subjected to BP. Twenty-one elite judo athletes (international level = 10; 21.7+/-1.9 years, 167.2+/-7.6 cm, 67.6+/ 9.4 kg, 15.7+/-1.9 years of practice; national level = 11; 21.9+/-3.0 years, 167.5+/-9.1 cm, 71.8+/-16.5, 15.9+/-3.0 years of practice) were subjected to 13 week BP training (5-week accumulation phase [ACP], 5-week transmutation phase [TP], and 3-week realization phase [RP]). The judo-specific performance (SJFT) increased as there was observed a decrease in the SJFT index (final heart rate [HR] (bpm) + HR1 min after the test divided by the number of throws) for both NG (effect size [ES] = 0.83) and IG (ES = 0.53) from ACP to TP (p < 0.05). The row exercise maximal strength decreased (p < 0.05; ES = 1.35) after the ACP but returned to the baseline level after the TP, for the whole group (ES = 1.39). The athletes did seem to cope appropriately with the demands of BP, as besides increases in SJFT performance no significant changes were observed for cortisol and testosterone concentrations. This is the first study to demonstrate that judo athletes from different competitive levels subjected to BP improved SJFT, likely due to an appropriate balance between training loads and recovery. Thus, the BP approach may be a useful alternative periodization strategy for high-level judo athletes. PMID- 29472741 TI - Effects of order and sequence of resistance and endurance training on body fat in elementary school-aged girls. AB - The purpose of this study was to analyse the effects of order and sequence of concurrent resistance and endurance training on body fat percentage (BFP) in a large sample of elementary school-aged girls. One hundred and twenty-six healthy girls, aged 10-11 years (10.95 +/- 0.48 years), were randomly assigned to six groups to perform different training protocols per week for 8 weeks: Resistance only (R), Endurance-only (E), Concurrent Distinct Endurance-Resistance (CDER), Concurrent Parallel Endurance-Resistance (CPER), Concurrent Parallel Resistance Endurance (CPRE), and a Control group (C). In R and E, the subjects performed single sessions of resistance or endurance exercises, respectively (two days per week). In CDER, resistance-endurance training was performed on different days each week (four days per week). CPER and CPRE performed single-session combined endurance-resistance training or combined resistance-endurance training, respectively, each week (two days per week). After an 8-week training period, BFP decreased in all experimental groups (CPER: 13.3%, p< 0.05; CPRE: 13.8%, p<0.001; E: 1.9%, p>0.05; R: 5.0%, p>0.05; and CDER: 5.6%, p>0.05). However, a significant difference was found in CPER and CPRE when compared to CDER, E, and R, indicating that training sequence may influence BFP. All programmes were effective, but CPER and CPRE obtained better results for BFP than CDER, E, or R. The effects of concurrent resistance and endurance training on body fat percentage can be mediated by order and sequence of exercise. These results provide insight into optimization of school-based fat loss exercise programmes in childhood. PMID- 29472742 TI - Effects of high-intensity interval training on body composition, aerobic and anaerobic performance and plasma lipids in overweight/obese and normal-weight young men. AB - To examine the effects of short high-intensity interval training (HIIT) on body composition, physical performance and plasma lipids in overweight/obese compared to normal-weight young men. Nine overweight/obese and nine normal-weight men (control group) aged 17 to 20 years underwent a HIIT programme three times per week for eight weeks. Body composition, indices of aerobic [maximal aerobic velocity (MAV) and maximal oxygen uptake (VO2max)] and anaerobic [squat jump (SJ), counter-movement jump (CMJ), five-jump test (FJT), 10-m and 30-m sprint] performances, as well as fasting plasma lipids, were assessed in the two groups at PRE and POST HIIT. The HIIT programme resulted in significant reductions in body mass (-1.62%, P=0.016, ES=0.11) and fat mass (-1.59%, P=0.021, ES=0.23) in obese, but not in normal-weight subjects. MAV (+5.55%, P=0.005, ES=0.60 and +2.96%, P=0.009, ES=0.82), VO2max (+5.27%, P=0.006, ES=0.63 and +2.88%, P=0.009, ES=0.41), FJT (+3.63%, P=0.005, ES=0.28 and +2.94%, P=0.009, ES=0.52), SJ (+4.92%, P=0.009, ES=0.25 and +6.94%, P=0.009, ES=0.70) and CMJ (+6.84%, P=0.014, ES=0.30 and +6.69%, P=0.002, ES=0.64) significantly increased in overweight/obese and normal-weight groups, respectively. 30-m sprint time significantly decreased in both groups (-1.77%, P=0.038, ES=0.12 and -0.72%, P=0.030, ES=0.16). Plasma total cholesterol (-11.8%, P=0.026, ES=0.96), LDL cholesterol (-11.9%, P=0.050, ES=0.77) and triglycerides (-21.3%, P=0.023, ES=1.08) significantly decreased in the obese group, but not in the normal-weight group. The eight-week HIIT programme resulted in a slight improvement in physical fitness and a significant decrease in plasma lipids in the obese. Short duration HIIT may contribute to an improved cardiometabolic profile in the obese. PMID- 29472743 TI - Performance analysis of male handball goalkeepers at the World Handball championship 2015. AB - Goalkeepers have a very important role in handball. In coaching communities it is well recognized that goalkeepers' performances can predict team ranking in major tournaments. Despite this, few studies have been conducted on elite goalkeepers participating in World Championships. Therefore, the purpose of this study was to analyse goalkeepers' save performance during the 88 matches of the 2015 men's World Championships tournament. Goalkeepers from 24 national teams were analysed using a tracking camera system and bespoke software (Prozone Handball V.1.2, Prozone, Leeds, UK). The purpose of this study was to examine time-motion performance parameters and to evaluate the save rates for each goalkeeper. The mean total distance covered in a game by the goalkeepers was 1634+/-999 m. Goalkeepers spent most of the time walking or standing. The total amount of shots to the goal was 6893, with a mean save percentage of 30% (2088 saves). A significant relationship was identified between the goalkeepers' save statistics and the final team rankings. The save rate is important for teams to achieve a higher ranking, and therefore the selection and training of goalkeepers requires more than just assessing physical abilities. The throwing distribution and success/save rate during the Qatar 2015 Men Handball World Championships suggest strong and weak parts of the goal area, and coaches can use this information to adjust their training approaches for both goalkeepers and shooters. PMID- 29472744 TI - Properties of body composition of female representatives of the Polish national fencing team - the sabre event. AB - Fencing is a combat sport whose form of direct confrontation involves hitting the opponent with a weapon. The purpose of the study was to determine the properties of body composition of female representatives of the Polish national fencing team. The study involved 11 female athletes of the Polish national fencing team. Their age was 16-22 years (19+/-2.32), body weight 52-78 kg (59.7+/-7.4), body height 158-183 cm (167.46+/-6.10) and the training experience 7.64+/-3.47 years. The reference group consisted of 153 students of Warsaw University of Technology (Poland). Twenty basic somatic characteristics were measured. The following indices were calculated: slenderness, Rohrer's, BMI, Manouvrier's, and pelvic shoulder indices. Density of the body, total body fat, active tissue, the overall profile of body composition and internal proportions of the body were determined. Analysis of internal proportions of factors of the athletes' body composition revealed significant differences in particular groups of features. The total size of the athletes' bodies is due to less-than-average magnitude of the length and stoutness characteristics and a high magnitude of adiposity (M = 0.63) in the Polish female national team of fencers (sabre) calculated from the normalized values for the control group. The proportions of features within the analysed factors revealed a significant advantage of the length of the upper extremity over the lower one and a distinct advantage of forearm musculature. The specific profile of body composition of female athletes practising sabre fencing is most likely due to long-term effects of training as well as the system of selection of persons with specific somatic prerequisites developed in the course of many years of training practice. PMID- 29472745 TI - Effects of seawater ingestion on lactate response to exercise in runners. AB - The aim of this study was to examine the effect of microfiltered and sterilized seawater ingestion on running performance in a hot environment. This cross-over, double-blind randomized trial included 12 experienced male runners. The subjects randomly consumed seawater (SW) or pure water (placebo) in an equivalent amount of 50 ml five minutes prior to running at 40% of their VO2 max for 95.0 +/- 18.5 min, at 30 degrees C, until they lost 3% of body weight. Every 20 minutes, a measurement of their body weight was taken and a blood lactate analysis was performed. The concentration of lactate was significantly lower after the running exercise in the SW condition compared to placebo. The results of this study provide evidence supporting the ergogenic effects of microfiltered and sterilized seawater ingestion on running performance and lactate production. PMID- 29472746 TI - Being an 'adolescent': The consequences of gendered risks for young people in rural Uganda. AB - The behaviour of adolescents is recognised increasingly as having substantial and long-term consequences for their health. We examined the meaning of 'adolescence' in southern Uganda with HIV-positive young people aged 11-24 years. Adolescent girls and boys are described differently in the local language (Luganda). Adolescence is described as a behavioural rather than a life course category and an inherently dangerous one. The practices, risks and consequences of 'adolescent' behaviour are highly gendered. Local understandings of adolescence are likely to have a significant impact on the efficacy of interventions designed to minimise their 'risky behaviour'. PMID- 29472748 TI - Efficacy and Safety of Oral Diclofenac Sustained release Versus Transdermal Diclofenac Patch in Chronic Musculoskeletal Pain: A Randomized, Open Label Trial. AB - Introduction: To compare the efficacy, safety, and tolerability of transdermal patches of diclofenac sodium with oral diclofenac sustained release (SR) in patients of chronic musculoskeletal MSK pain conditions. Materials and Methods: The eligible patients were given either transdermal diclofenac patch or tablet diclofenac SR. Pain was assessed at 2 and 4 weeks using a visual analog scale. Adverse events were recorded. Patients with 18-65 years old of either gender with score of >=4 on a 11-item numeric rating scale-numeric version of visual analog scale for pain with diagnosis of primary osteoarthritis (OA) of the knee or hand of at least 3 months duration, with independent radiological confirmation of OA or having pain associated with other MSK conditions such as soft-tissue rheumatism, cervical and lumbar back pain, and fibromyalgia, of at least 3 months duration were included in this study. Results: Transdermal diclofenac diethylamine patch and tablet diclofenac sodium sustained release (SR) do not significantly differ in the reduction of numerical rating scores at the end of 4 weeks (P = 0.8393). Conclusion: Transdermal diclofenac was equi-efficacious as tablet diclofenac sodium SR in reducing pain due to chronic MSK pain conditions.

AB - Calcium channel blockers (CCBs), particularly dihydropyridine-CCBs, (DHP-CCBs), have an established role in antihypertensive therapy, either as monotherapy or in combination with other antihypertensive drugs. Two hundred and fifty-one papers published in PubMed in English between January 1, 1990, and October 31, 2016, were identified using the keyword "lercanidipine." Lercanidipine is a lipophilic third-generation DHP-CCB, characterized by high vascular selectivity and persistence in the smooth muscle cell membranes. Lercanidipine is devoid of sympathetic activation, and unlike the first and second generation of DHP-CCBs, it dilates both the afferent and the efferent glomerular arteries, while preserving the intraglomerular pressure. In addition, lercanidipine prevents renal damage induced by angiotensin II and demonstrates anti-inflammatory, antioxidant, and anti-atherogenic properties through an increasing bioavailability of endothelial nitric oxide. It is associated with a regression of microvascular structural modifications in hypertensive patients. The efficacy of lercanidipine has been demonstrated in patients with different degrees of hypertension, in the young and elderly and in patients with isolated systolic hypertension. In patients with diabetes and renal impairment, lercanidipine displays a renal protection with a significant decrease of microalbuminuria and improvement of creatinine clearance. Lercanidipine is well tolerated and is associated with a very low rate of adverse events, particularly ankle edema, compared with amlodipine and nifedipine. In conclusion, lercanidipine produces a sustained blood pressure-lowering activity with a high rate of responder/normalized patients, associated with a favorable tolerability profile.

AB - We reported a series of patients who presented with LSP-induced movement disorders specifically, dyskinetic movements. We have presented one case of LSP induced parkinsonism and summarized ten cases of LSP-induced dyskinesia. The causality of the adverse drug reaction was assessed systematically using a validated rating system, and we extensively qualified the clinical presentation of each case of dyskinesia using a clinical rating scale. We described an unusual case of acute onset LSP-induced parkinsonism in a 56-year-aged female. The mean age of ten patients of LSP-induced dyskinesia was 65.3 years (standard deviation 10.4), and 25% of patients were female. They were consuming suspected medication for a median duration of 13 months (range 1-60 months). We noted LSP-induced dyskinesia was challenging to treat as its resolution is often incomplete even with adequate treatment. PMID- 29472752 TI - Low-Dose Mirtazapine-Induced Nightmares Necessitating its Discontinuation in a Young Adult Female. AB - Mirtazapine is a novel tetracyclic antidepressant which enhances noradrenergic and serotonergic transmission by blocking central alpha2-adrenergic auto- and hetero-receptors. Due to favorable safety and adverse effect profile, it is often viewed as a promising agent for treatment of depression. Particularly, its anxiolytic and sleep-improving properties have led to its favorable positioning for the management of depression with insomnia. Our objective is to describe a case of depression with treatment-emergent nightmares induced by mirtazapine. A 21-year-old female medical student was diagnosed with moderate depression with prominent insomnia and initiated on tablet mirtazapine 7.5 mg subsequent to a failed trial of selective serotonin reuptake inhibitor. On each of the next 7 days, she developed nightmares that were quite distressing and terrifying. As per the patient's request, tablets were stopped. The side effect abated within 2 days of stopping the agent, and this close temporal relationship suggests a causal role for mirtazapine in inducing the adverse reaction. Nightmares are usually associated with rapid eye movement (REM) sleep, and literature is inconsistent about the effect of mirtazapine on REM sleep parameters. Nevertheless, clinicians need to be forewarned about the possibility of developing treatment-limiting REM sleep phenomena such as nightmares when using antidepressants without prominent REM suppressant properties such as mirtazapine. The putative mechanisms behind these rare adverse reactions are discussed. PMID- 29472753 TI - Autopsy-proven Mirtazapine Withdrawal-induced Mania/Hypomania Associated with Sudden Death. AB - Manic episodes induced by antidepressant withdrawal are rarely reported. Mirtazapine is a tetracyclic, piperazinoazepine compound and is a noradrenergic, adrenergic, serotonergic, histaminergic, and muscarinic-antagonist antidepressant that is used for the treatment of major depression and other psychiatric illnesses. There are several reported cases of manic/hypomanic episodes induced by mirtazapine withdrawal based on suspected clinical symptoms that were not confirmed by autopsy and toxicology. We present the first reported case of mirtazapine withdrawal-induced mania/hypomania associated with sudden death and confirmed by autopsy and toxicology. Our patient was a 26-year-old male who had been diagnosed with schizophreniform disorder, borderline intellectual functioning, polysubstance abuse, mild mental retardation, and attention deficit hyperactive disorder. He took only mirtazapine in the final and terminal weeks of his life and stopped taking mirtazapine 4 days before his death. He exhibited a sudden manic/hypomanic episode and died during a physical altercation during this episode. A full autopsy with comprehensive toxicologic analysis of his body fluids and tissues was performed. Autopsy revealed that he died from blunt force trauma of the head, neck, and trunk with extremely low and markedly subtherapeutic levels of mirtazapine and desmethylmirtazapine in the blood (mirtazapine: 0.005 mg/L; desmethylmirtazapine 0.011 mg/L). Advanced selective radioligand and neurochemical assays for density and affinity-binding parameters of dopamine transporter and heat shock protein 70 did not reveal any evidence of excited delirium or autonomic hyperactivity state. We recommend that toxicologic analysis of blood for antidepressants should become routine parts of autopsy protocols for the investigation of sudden death following terminal manic/hypomanic episodes for further elucidation of mania/hypomania induced by antidepressant withdrawal. PMID- 29472754 TI - Prevalence of Obesity After Spinal Cord Injury. AB - The prevalence of obesity has been continuously increasing in the United States. Obesity has crossed the borders of the able-bodied populations and extended to populations with disabilities, including spinal cord injury (SCI). The magnitude and the prevalence of obesity after SCI are not clearly defined. The purpose of the current review is to discuss the body of literature on the prevalence of obesity among individuals with SCI. The review will show that the prevalence of obesity after SCI is an issue that needs to be further addressed and specifically correlated to mortality rates in SCI. Body mass index (BMI) criteria need to be adjusted to meet the changes in body composition after SCI, specifically increasing fat mass and percent body fat. Prevalence of overweight and obesity in SCI by sex, age, and ethnic group needs further investigation to determine the actual magnitude of the problem, which appears to exceed epidemic proportions. Moreover, SCI-specific factors such as level of injury, American Spinal Injury Association (ASIA) impairment classification, and time since injury need to be further correlated to the prevalence of obesity after SCI.

AB - PH46A, belonging to a class of 1,2-Indane dimers, has been developed by our research group as a potential therapeutic agent for the treatment of inflammatory and autoimmune diseases. The initial synthetic route to PH46A gave a low overall yield, due in large part to the generation of undesired diastereoisomer 5 and the unwanted enantiomer (R,R)-8 during the synthesis. The aim of this work was to carry out a comprehensive investigation into the stereoselective synthesis of PH46A. Significant progress was made on the ketone reduction step, where the use of triisobutylaluminum [TiBA, Al(iBu)3] afforded high selectivity for the target diastereoisomer (rac)-6, compared to the unfavorable ratio obtained using a previous process. This enabled a multikilo scale synthesis of PH46A in a GMP environment. Further, a brief proof-of-principle investigation was carried out using an achiral phase transfer catalyst (PTC) for alkylation at the methine carbon of the parent indanone. PMID- 29472756 TI - Robotic TAPP Ventral Hernia Repair: Early Lessons Learned at an Inner City Safety Net Hospital. AB - Background and Objectives: Ventral hernia repair is one of the most commonly performed general surgery procedures, and minimally invasive approaches are increasingly preferred. The physiologic repair offered by the preperitoneal approach is favorable, with reduced complications, but it remains a technical challenge. The robotic platform allows for enhanced instrument flexibility and ease of operation. We conducted a retrospective review of our experience with robotic transabdominal preperitoneal repair (rTAPP) versus robotic intraperitoneal onlay mesh (rIPOM) at a tertiary care hospital in an urban setting. Methods: We reviewed the records of patients undergoing minimally invasive ventral hernia repair from March 2014 through March 2017. Demographics, complication rates, and operative time were compared by t test and Chi square test, as applicable. Results: Sixty-three patients met the criteria for inclusion in the study. Of those, 27 underwent ventral hernia repair with rIPOM and 36 with rTAPP, with no major intraoperative complications. There were no significant differences in demographics between the 2 groups in age, BMI, and sex. The difference in mean operative time was not significant (rIPOM 167.26 [SD 51.76] minutes vs rTAPP 158.84 minutes [SD 61.5]; P = .57), whereas mean console time was significantly different (rIPOM 70.88 minutes [SD 32.88] vs rTAPP 90.26 [SD 31.17]; P = .018). Postoperative complications occurred only with rIPOM and included urinary retention, seroma, and fever. Conclusions: rTAPP is a promising alternative to rIPOM, with reduced complications without adding significant operative time, and may allow for reduced costs. PMID- 29472757 TI - Trifecta Outcomes to Assess Learning Curve of Robotic Partial Nephrectomy. AB - Background and Objectives: The learning curve for achieving desirable perioperative outcomes in robot-assisted partial nephrectomy (RAPN) has not been well studied. Information is available regarding "trifecta" outcomes of no complications, no positive margins, warm ischemia time (WIT) of <=25 minutes, and a <=15% decrease in postoperative glomerular filtration rate (GFR). This study was conducted to assess the impact of the learning curve on surgical outcomes in patients undergoing RAPN. Methods: We reviewed 131 consecutive patients who underwent RAPN by a single, fellowship-trained surgeon from October 2007 through June 2015. Patients were divided into 4 subgroups, and mean perioperative values were compared. The learning curve was evaluated as the time it took the surgeon to attain a trifecta outcome. Results: Means for the RENAL Nephrometry Score, procedure length, WIT, and estimated blood loss (EBL) were 5.3 +/- 1.2, 172.1 +/- 43.5 minutes, 22.7 +/- 7.0 minutes, and 267.2 +/- 341.8 mL, respectively. Significance was noted for differences in WIT (P = .50), postoperative creatinine (P = .006), postoperative estimated (e)GFR (P = .40), and percentage change in creatinine (P = .023). The learning curve for achieving positive outcomes was noted in >61-90 cases after 66-80 months of performing minimally invasive partial nephrectomy surgeries at a rate of 20 cases per year. Conclusion: RAPN is a safe, feasible procedure with slightly better surgical outcomes than laparoscopic partial nephrectomy (LPN). In the hands of an experienced surgeon, the learning curve for achieving trifecta outcomes can involve a significant number of cases over several years. PMID- 29472758 TI - Predictors of Reoperation and Failure to Rescue in Bariatric Surgery. AB - Background and Objectives: Morbidity and mortality have been shown to increase several-fold in patients who have undergone bariatric surgery and returned to the operating room after their initial procedures. Failure-to-rescue (FTR) analyses allow for an understanding of patient management and outcomes that is more distinguished than assessments of adverse occurrences and mortality rates alone. The objective of this study was to assess failure to rescue (FTR) and the characteristics and outcomes of patients undergoing reoperation after laparoscopic gastric bypass (LGBP) and laparoscopic sleeve gastrectomy (LSG). Methods: The American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) participant data files were accessed to identify patients >18 years of age who underwent LGBP and LSG from 2011 through 2015. Patients were further classified into 3-day reoperation and nonreoperation cohorts. Patient demographics, comorbidities, and baseline health characteristics were collected. Pertinent outcomes, complications, and FTR were analyzed. Results: A total of 96,538 patients were included. Of those, 1,850 (1.92%) returned to the operating room, and 94,688 (98.08%) did not. Patients who underwent reoperation had a greater likelihood of having any complication (72.20% vs. 51.29%; P < .0001) and had a higher overall mortality rate (1.46% vs. 0.10%, P < .0001). The FTR rates were 2.01% in the reoperation group and 0.14% in the nonreoperation group (P < .0001). Conclusion: Patients who undergo LGBP and LSG and have reoperations are at higher risk of developing complications with subsequent mortality. PMID- 29472759 TI - TEP With Long-Term Resorbable Mesh in Patients With Indirect Inguinal Hernia. AB - Background and Objectives: The role of long-term degradable implants in reducing the risk of chronic postoperative pain after inguinal hernia repair is still unclear. A pilot study using a synthetic long-term resorbable mesh in Lichtenstein repair showed good results regarding pain and discomfort in patients with indirect inguinal hernia (IH) without recurrences, but higher recurrence rate in patients with direct inguinal hernia (DH). The purpose of this study was to assess the incidence of pain and early recurrence in patients with LIH surgically treated with the TEP technique using a long-term degradable mesh. This is the first human study to use long-term degradable mesh with the TEP approach. Methods: This study was prospective, including 35 primary IHs surgically treated with TEP repair using TIGR Mesh (Novus Scientific Pte, Ltd, Singapore). At the 1 year follow-up recurrence was assessed by clinical examination and the incidence of pain or discomfort was assessed before and after surgery by Visual Analog Scale (VAS) and Inguinal Pain Questionnaire (IPQ). Results: After 12 months, no patients had chronic pain. Only 1 (2.8%) patient reported pain using the VAS (score = 2), and 4 patients reported pain that could easily be ignored. All 4 patients reported less pain 1 year after the operation using both IPQ and VAS, compared with the preoperative assessment. One patient (2.8%) developed a recurrence 20 months after the primary operation. Conclusion: TEP repair using a synthetic long-term resorbable mesh was found to be safe and promising regarding pain and discomfort at 1-year follow-up in patients with IH. Longer follow-up is necessary to establish the risk of recurrence. PMID- 29472760 TI - Genetic Diversity and Functional Analysis of Sigma Factors in Enterobacter cloacae Complex Resourced From Various Niche. AB - Sigma factors are bacterial transcription factors that bind the core RNA polymerase and direct transcription initiation at a specific promoter site. These specialized sigma factors bind the promoters of genes appropriate to the environmental conditions and selectively increase the transcription of those genes. Here, we attempt to identify sigma factors in 5 genomes belonging to the Enterobacter cloacae complex (Ecc), a group of gram-negative bacteria that are important nosocomial pathogens. This process includes the identification of orthologous sequences, conserved motifs, domains, families, phylogenetic profiles, and protein-protein associations of these components. Based on the reference genome, genome-wide comparison revealed that the genomes of Enterobacter asburiae JCM6051, Enterobacter nimipressuralis CIP 104980, Enterobacter hormaechei ATCC49162, Enterobacter kobei JCM 8580, and Enterobacter ludwigii EN-119 encode 10 sigma factors that exist in the reference strain Enterobacter cloacae subsp cloacae ATCC13047. Moreover, the sequence similarity, protein domains and families of the sigma factors, protein-protein association, and phylogenetic profile indicate that the sigma factor proteins of these 5 strains may have evolutionary relatedness and functional characteristics important to their various environmental niches. Interestingly, the absence of RpoS in E kobei, which contributes to bacterial survival under environmental stress conditions, indicates that RpoS might have been independently acquired and may play different roles relating to pathogenicity, host range determination, and/or niche adaptation. Future work such as RNA sequencing will be directed towards investigating the roles that these sigma factors play in the biology of the Ecc. PMID- 29472761 TI - More new deep-reef basslets (Teleostei, Grammatidae, Lipogramma), with updates on the eco-evolutionary relationships within the genus. AB - Two new Lipogramma basslets are described, L. barrettorum and L. schrieri, captured during submersible diving to 300 m depth off Curacao, southern Caribbean. Superficially resembling L. robinsi in having 11-12 bars of pigment on the trunk, L. barrettorum is distinct from L. robinsi in having a stripe of blue white pigment along the dorsal midline of the head (vs. a cap of yellow pigment), in patterns of pigment on the median fins, and in having 8-10 gill rakers on the lower limb of the first arch (vs. 11-12). Lipogramma schrieri is distinct from all congeners in having seven or eight dark bars of pigment on the trunk and broad, irregular, whitish blue markings on the dorsal portion of the head. The new species are genetically distinct from one another and from seven other Lipogramma species for which genetic data are available. A phylogenetic hypothesis derived from mitochondrial and nuclear genes suggests that the new species belong to a clade that also comprises L. evides and L. haberi. Collectively those four species are the deepest-living members of the genus, occurring at depths predominantly below 140 m. This study thus provides further evidence of eco-evolutionary correlations between depth and phylogeny in Caribbean reef fishes. Tropical deep reefs are globally underexplored ecosystems, and further investigation of Caribbean deep reefs undoubtedly will provide samples of species for which no genetic material currently exists and reveal more cryptic species diversity in the genus. PMID- 29472763 TI - Rhachotropis (Eusiroidea, Amphipoda) from the North East Atlantic. AB - The genus Rhachotropis has the widest geographic and bathymetric distribution of all amphipod genera worldwide. Molecular and morphological investigations of specimens sampled around Iceland and off the Norwegian coast allow the first insights into the relationships of North East Atlantic Rhachotropis. The 31 cytochrome oxidase subunit I (COI) sequences generated for this study were assigned 13 Barcode Index Numbers (BINs) in the Barcode of Life database (BOLD), of which 12 are new to the database. Molecular analyses of COI and 16S sequences could not confirm a theory that depth has a greater influence on the phylogeny of Rhachotropis than geographic distance. Although the North East Atlantic is a well studied area, our molecular investigations revealed the genus Rhachotropis may contain cryptic species, which indicates a higher biodiversity than currently known. For example, the specimens which key to Rhachotropis helleri is a complex of three COI clades, two of which cannot be identified with morphological traits. One specimen of each of the clades in the cladogram was documented by high definition photographs. A special focus was on the visual morphology of the eyes, as this character shows interspecific differences within the genus Rhachotropis in response to fixation in ethanol. Detailed morphological investigation showed that some clades thought to be indistinguishable can be separated by minute but consistent morphological characters. Datamining Genbank to examine all registered COI-sequences of R. aculeata, the only previously known Rhachotropis BIN in the North Atlantic and sub-Arctic, showed R. aculeata to be subdivided by an Arctic and a North Atlantic population. PMID- 29472762 TI - A genetic fingerprint of Amphipoda from Icelandic waters - the baseline for further biodiversity and biogeography studies. AB - Amphipods constitute an abundant part of Icelandic deep-sea zoobenthos yet knowledge of the diversity of this fauna, particularly at the molecular level, is scarce. The present work aims to use molecular methods to investigate genetic variation of the Amphipoda sampled during two IceAGE collecting expeditions. The mitochondrial cytochrome oxidase subunit 1 (COI) of 167 individuals originally assigned to 75 morphospecies was analysed. These targeted morhospecies were readily identifiable by experts using light microscopy and representative of families where there is current ongoing taxonomic research. The study resulted in 81 Barcode Identity Numbers (BINs) (of which >90% were published for the first time), while Automatic Barcode Gap Discovery revealed the existence of 78 to 83 Molecular Operational Taxonomic Units (MOTUs). Six nominal species (Rhachotropis helleri, Arrhis phyllonyx, Deflexilodes tenuirostratus, Paroediceros propinquus, Metopa boeckii, Astyra abyssi) appeared to have a molecular variation higher than the 0.03 threshold of both p-distance and K2P usually used for amphipod species delineation. Conversely, two Oedicerotidae regarded as separate morphospecies clustered together with divergences in the order of intraspecific variation. The incongruence between the BINs associated with presently identified species and the publicly available data of the same taxa was observed in case of Paramphithoe hystrix and Amphilochus manudens. The findings from this research project highlight the necessity of supporting molecular studies with thorough morphology species analyses. PMID- 29472764 TI - An alternative approach for evaluating the phenotypic virulence factors of pathogenic Escherichia coli. AB - Escherichia coli is a recognized zoonotic food-borne pathogen; however, the use of polymerase chain reaction (PCR) in the underdeveloped countries to differentiate pathogenic from non-pathogenic E. coli is a problematic issue. Our grail was to assess the phenotypic virulence markers motility, hemolysin, congo red agar, embryo lethality assay and serum resistance for pathogenic E. coli (PEC) correlated to PCR tests which is currently used world-wide to evaluate the PEC. The 448 strains of Escherichia coli that were isolated from different sources, were characterized for phenotypic virulence factors such as motility, hemolysin, Congo red binding, Embryo Lethality assay (ELA) and serum resistance, as well as antibiotic susceptibility using disc diffusion method to 23 antibiotics. Results exhibited 100% motility and Congo red binding, 97.1% for hemolysin production and 90.2% in the ELA. As a result, we were able to hypothetically conclude that the aforementioned virulence markers are plain, straightforward, economical, rapid, more dynamic, uncomplicated methodology, duplicatable and cost next to nothing when compared to the molecular PCR. Their implementation in a diagnostic microbiology laboratory for vetting is a rewarding task in the underdeveloped countries. It augments endeavors to minimize the use of PCR in our investigations especially during epidemiological and outbreak investigations of PEC. PMID- 29472765 TI - Effect of dietary fish meal replacement by red algae, Gracilaria arcuata, on growth performance and body composition of Nile tilapia Oreochromis niloticus. AB - A 12-week long feeding experiment was initiated to evaluate the effect of dietary supplementation of red algae, Gracilaria arcuata, on the growth performance, feed utilization and body composition of Nile tilapia Oreochromis niloticus (Linnaeus, 1758). The fish were fed with an algae-free control diet (C) and three experimental diets which replaced conventional fish meal with varying levels of dried G. arcuata (20%, 40% and 60%, represented as G20, G40 and G60, respectively). The growth parameters of final weight (FW), weight gain (WG), percentage of weight gain (WG%), daily growth rate (DGR) and specific growth rate (SGR) were significantly reduced (P < 0.05) at all levels of algae incorporation compared to the control diet. Moreover, the negative impact of Gracilaria meal on the growth performance of Nile tilapia increased as the proportion of algae in the diet increased, with fish on diet G20 exhibiting a significantly higher growth performance than the fish on either of the G40 and G60 diets. On the other hand, the feed utilization parameters feed conversion ratio (FCR) and protein efficiency ratio (PER) did not show significant differences between the fish in the control group and those on diet G20, although poorer FCR and PER outcomes were achieved in the case of fish on diet G60. The content of moisture, protein and ash in muscle and carcass increased as the proportion of Gracilaria meal in the diets increased, but the reverse was true for lipid level. These results indicate that incorporation of less than 20% red algae, Gracilaria arcuata, could be feasible in the diet of Nile tilapia and further studies are recommended to optimize the level of algae to improve growth performance. PMID- 29472766 TI - Aquatic ecosystem health and trophic status classification of the Bitter Lakes along the main connecting link between the Red Sea and the Mediterranean. AB - The Bitter Lakes are the most significant water bodies of the Suez Canal, comprising 85% of the water volume, but spreading over only 24% of the length of the canal. The present study aims at investigation of the trophic status of the Bitter Lakes employing various trophic state indices, biotic and abiotic parameters, thus reporting the health of the Lake ecosystem according to the internationally accepted classification criteria's. The composition and abundance of phytoplankton with a dominance of diatoms and a decreased population density of 4315-7376 ind. l-1 reflect the oligotrophic nature of this water body. The intense growth of diatoms in the Bitter Lakes depends on silicate availability, in addition to nitrate and phosphate. If the trophic state index (TSI) is applied to the lakes under study it records that the Bitter Lakes have an index under 40. Moreover, in the total chlorophyll-a measurements of 0.35-0.96 ug l-1 there are more indicative of little algal biomass and lower biological productivity. At 0.76-2.3 ug l-1, meanwhile, the low quantity of Phosphorus is a further measure of low biological productivity. In the Bitter Lakes, TN/TP ratios are high and recorded 147.4, and 184.7 for minimum and maximum ratios, respectively. These values indicate that in Bitter lakes, the limiting nutrient is phosphorus and confirm the oligotrophic status of the Bitter Lakes. The latter conclusion is supported by Secchi disc water clarity measurements, showing that light can penetrate, and thus algae can photosynthesize, as deep as >13 m. This study, therefore, showed that the Bitter Lakes of the Suez Canal exhibit oligotrophic conditions with clear water, low productivity and with no algal blooming. PMID- 29472767 TI - Anti-hypertensive and cardioprotective effects of a novel apitherapy formulation via upregulation of peroxisome proliferator-activated receptor-alpha and -gamma in spontaneous hypertensive rats. AB - Ventricular remodeling is associated with many heart diseases, and ventricular remodeling induced by hypertension can be fatal independent of hypertension. In this study, we prepared a novel apitherapy formulation, designated Bao-Yuan-Ling (BYL), which contained propolis, royal jelly, and bee venom, to treat spontaneous hypertensive rats (SHRs). We then evaluated the pharmacology of BYL and the potential mechanisms through which BYL affects hypertension and ventricular remodeling. We found that BYL treatment could reduce blood pressure in SHRs. Thereafter, we found that BYL treatment reduced serum levels of angiotensin II, endothelin 1, and transforming growth factor-beta and improved the myocardial structure. Moreover, the results of quantitative real-time polymerase chain reaction indicated that BYL treatment could upregulate the mRNA expression of peroxisome proliferator-activated receptor (PPAR)-alpha and PPAR-gamma. Thus, we could conclude that BYL had hypotensive and cardioprotective effects in SHRs, potentially through improvement of myocardial energy metabolism. PMID- 29472768 TI - Effect of Zhen Qi Fu Zheng granules on the bone marrow depression model induced by Zidorf. AB - Zidorf is a commonly used drug for the treatment of AIDS, the most common side effects of AZT was bone marrow depression. Therefore, we investigated the effects of Zhen Qi Fu Zheng (AQFZ) granules on the model of bone marrow depression induced by AZT. We showed that the high, medium and low doses of AQFZ granules could increase the number of WBC in the mice model induced by AZT, and the difference was significant (P < 0.01) compared with the model group. Each dose of AQFZ granules can increase the thymus cortex thickness, the number of thymus lymphocytes, spleen nodule size, the number of lymphocytes in the spleen (P < 0.01). The medium dose of AQFZ granules can also significantly improve the number of BMC in the bone marrow depression model (P < 0.01). As well as, the low dose of AQFZ granules can clearly increase the number of nucleated cells in a bone marrow (P < 0.05) and IL-2blood serum. So, AQFZ granules can improve and regulate the hemogram, bone marrow and immune level of bone marrow depression model induced by AZT. PMID- 29472769 TI - The mechanisms and process of acephate degradation by hydroxyl radical and hydrated electron. AB - The degradation process of acephate in aqueous solution with *OH and [Formula: see text] produced by 60Co-gamma irradiation and electron pulse radiolysis was studied in the present paper. In the aqueous solution, acephate reacted with [Formula: see text] and transformed to transient species which can absorb weakly in the wavelength range of 300-400 nm and decay very fast. According to the decay of hydrated electron, the reaction rate constant of [Formula: see text] and acephate is (3.51 +/- 0.076) * 109 dm3.mol-1.s-1. The transient species produced in the reaction of *OH and acephate do not distinctly absorb the light in the wavelength range of 300-700 nm, so the decay and kinetics of the transient species cannot determinedirectly. The competing reaction of KSCN oracephate with *OH were studied to obtain the reaction rate constant of *OH and acephate, which is (9.1 +/- 0.11) * 108 dm3.mol-1.s-1. Although acetylamide and inorganic ions were determined in the products of the reaction of acephate with *OH or [Formula: see text], the concentration of inorganic ions in the products of the reaction of acephate with *OH is higher than that in the product of the reaction of acephate with [Formula: see text]. Moreover, there were sulfide in the products of the reaction of acephatewith [Formula: see text]. The degradation pathways of acephate by *OH and [Formula: see text] were also proposed based on the products from GC-MS. PMID- 29472770 TI - Study on biomolecules in extractives of Camellia oleifera fruit shell by GC-MS. AB - This study aims to present an integrated process that can be used to produce biomedical and biological active components from the fruit shell of Camellia oleifera Abel. Through the Foss method, Aldehyde, acid compounds, acyl and alcohol compounds account for 22.7, 15.93, 0.24 and 61.13% of the extractives which were extracted from Camellia oleifera fruit shell by methanol solvents. Furfural, Pyrazole-4-carboxaldehyde, 1-methyl- and 5-Hydroxymethylfurfural account for 4.74, 1.22 and 58.78% of the extractives which were extracted from the fruit shell of Camellia oleifera Abel by ethanol solvents. Aldehyde, acid and amine compounds account for 5.01, 56.18 and 7.20% of the extractives which were extracted from the fruit shell of Camellia oleifera Abel by ethyl acetate solvents. The extractives of fresh flesh of bayberry were rich in rare drug, biomedical and biological activities. PMID- 29472771 TI - A security mechanism based on evolutionary game in fog computing. AB - Fog computing is a distributed computing paradigm at the edge of the network and requires cooperation of users and sharing of resources. When users in fog computing open their resources, their devices are easily intercepted and attacked because they are accessed through wireless network and present an extensive geographical distribution. In this study, a credible third party was introduced to supervise the behavior of users and protect the security of user cooperation. A fog computing security mechanism based on human nervous system is proposed, and the strategy for a stable system evolution is calculated. The MATLAB simulation results show that the proposed mechanism can reduce the number of attack behaviors effectively and stimulate users to cooperate in application tasks positively. PMID- 29472772 TI - Effects of Decitabine on the proliferation of K562 cells and the expression of DR4 gene. AB - Objective: To investigate the role of DR4 gene in the occurrence, development and prognosis of acute myeloid leukemia (AML), find a new regulatory gene of Decitabine for the treatment of AML, namely DR4 gene, and explore the molecular mechanism of AML in the treatment of AML. Methods: The methylation level and the mRNA expression level of DR4 gene promoters of bone marrow mononuclear cells in 122 patients with newly diagnosed AML and 24 patients with iron deficiency anemia (IDA) were detected using Methylation specific PCR (MS-PCR) and Q-RT-PCR, respectively, and a correlation analysis of them was conducted. The effects of Decitabine on the proliferation of K562 cells were detected using CCK-8 assay. Then, the effects of Decitabine on the methylation level and the mRNA expression level of DR4 genes of K562 cells treated with Decitabine were detected using MS PCR and Q-RT-PCR, respectively. The effects of Decitabine on the cell cycle and apoptosis of K562 cells were detected using flow cytometry. Results: Compared with the control group, the methylation level (P = .002) of DR4 genes of bone marrow mononuclear cells in patients with newly diagnosed AML was high. The methylation level (P = .01) of DR4 genes of bone marrow mononuclear cells in patients of the positive group of enlargement of liver, spleen and lymph node was lower than that of the negative group, and the methylation level (P = .006) of DR4 genes in patients of the high risk group of clinical stage was lower than that of the low risk group, and the methylation level (P = .03) of DR4 genes in patients of the group where patients did not achieve complete remission (CR1) after a course of induction chemotherapy was lower than that of the group where patients achieved complete remission (CR1) after a course of induction chemotherapy. There was a significant negative correlation (P < .01) between the methylation level and the mRNA expression level of DR4 genes of bone marrow mononuclear cells in 122 patients with newly diagnosed AML. After the K562 cells were treated with Decitabine for 48 h, the methylation level of DR4 gene promoters gradually decreased, while the mRNA expression level of DR4 genes gradually increased, both of which showed a concentration-dependent relationship. After the K562 cells were treated with 5 umol/L Decitabine for 48 h, the K562 cells in G0/G1 phase and G2/M phase increased significantly, and the K562 cells in S phase decreased significantly. Conclusion: DR4 gene played an important role in the occurrence and development of AML. Decitabine can effectively inhibit the proliferation of K562 cells, which probably partly because it can terminate the methylation effect of DR4 gene promoters and restore the mRNA expression of DR4 genes. PMID- 29472773 TI - Effects of age on slaughter performance and meat quality of Binlangjang male buffalo. AB - Twelve representative buffalo were selected from 22 suckling calves, 41 weaned calves, 57 reserve bulls and 20 adult bulls for slaughter. The study aims to assess the effect of age on dressing percentage, meat percentage and carcass meat yield and physico-chemical properties of longissimus dorsi and biceps femoris, and to evaluate the correlation between live weight and marbling, backfat thickness, rib eye area. The results showed that the slaughter performance and meat quality of Binlangjang male buffalo showed an obvious change with age. The dressing percentage decreased from 54.93% to 51.22% with the increase of age, while meat percentage and carcass meat yield increased gradually with age, which were 34.58-38.59%, 62.95-75.34%; Marbling, backfat thickness and rib eye area increased with age, and there was significant difference between the situation before 3 months and after 12 months of age (P < 0.05). The moisture content was maximum at birth, which then gradually decreased, but the difference was insignificant (P > 0.05). The levels of fat, protein, cholesterol and inosine acid were significantly different before 3 months of age from those after 12 months (P < 0.05). Cholesterol content was negatively correlated with age, the minimum was 80.25 mg/100 g; Inosine acid content increased with age, reaching 133.11 mg/100 g. Marbling, backfat thickness, rib eye area had a high correlation with live weight, with correlation coefficients respectively at 0.9096, 0.9291, 0.9551. Based on the prediction model of live weight, Buffaloes was suitable for slaughtering for superior slaughter performance and meat quality after 24 months of age. PMID- 29472774 TI - 5,7-Dimethoxycoumarin prevents chronic mild stress induced depression in rats through increase in the expression of heat shock protein-70 and inhibition of monoamine oxidase-A levels. AB - The current study was aimed to investigate the role of 5,7-dimethoxycoumarin in the prevention of chronic mild stress induced depression in rats. The chronic mild stress rat model was prepared using the known protocols. The results from open-field test showed that rats in the chronic mild stress group scored very low in terms of crossings and rearings than those of the normal rats. However, pre treatment of the rats with 10 mg/kg doses of 5,7-dimethoxycoumarin prevented decline in the locomotor activity by chronic mild stress. The level of monoamine oxidase-A in the chronic mild stress rat hippocampus was markedly higher. Chronic mild stress induced increase in the monoamine oxidase-A level was inhibited by pre-treatment with 10 mg/kg doses of 5,7-dimethoxycoumarin in the rats. Chronic mild stress caused a marked increase in the level of caspase-3 mRNA and proteins in rat hippocampus tissues. The increased level of caspase-3 mRNA and protein level was inhibited by treatment of rats with 5,7-dimethoxycoumarin (10 mg/kg). 5,7-Dimethoxycoumarin administration into the rats caused a marked increase in the levels of heat shock protein-70 mRNA and protein. The levels of heat shock protein-70 were markedly lower both in normal and chronic mild stress groups of rats compared to the 5,7-dimethoxycoumarin treated groups. Thus 5,7 dimethoxycoumarin prevented the chronic mild stress induced depression in rats through an increase in the expression of heat shock protein-70 and inhibition of monoamine oxidase-A levels. PMID- 29472775 TI - Resveratrol, an antioxidant, protects spinal cord injury in rats by suppressing MAPK pathway. AB - Resveratrol, a polyphenol found in various plants, including grapes, plums and peanuts has shown various medIRInal properties, including antioxidant, protection of cardiovascular disease and cancer risk. However, the effects of resveratrol on spinal cord reperfusion injury have not been investigated. Hence, the present study was designed to evaluate the effect of resveratrol on nitric oxide synthase (iNOS)/p38MAPK signaling pathway and to elucidate its regulating effect on the protection of spinal cord injury. Spinal cord ischemia-reperfusion injury (IRI) was performed by the infrarenal abdominal aorta with mini aneurysm clip model. The expressions of iNOS and p38MAPK and the levels of biochemical parameters, including nitrite/nitrate, malondialdehyde (MDA), advanced oxidation products (AOPP), reduced glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT) were measured in control and experimental groups. IRI-induced rats treated with 10 mg/kg resveratrol protected spinal cord from ischemia injury as supported by improved biological parameters measured in spinal cord tissue homogenates. The resveratrol treatment significantly decreased the levels of plasma nitrite/nitrate, iNOS mRNA and protein expressions and phosphorylation of p38MAPK in IRI-induced rats. Further, IRI-produced free radicals were reduced by resveratrol treatment by increasing enzymatic and non-enzymatic antioxidant levels such as GSH, SOD and CAT. Taken together, administration of resveratrol protects the damage caused by spinal cord ischemia with potential mechanism of suppressing the activation of iNOS/p38MAPK pathway and subsequent reduction of oxidative stress due to IRI. PMID- 29472776 TI - Tanshinone IIA suppress the proliferation of HNE-1 nasopharyngeal carcinoma an in vitro study. AB - Nasopharyngeal carcinoma (NPC) at present is considered to be one of the fatal diseases detected commonly in the people belonging to Southeast Asia and southern China. According to the WHO reports among the detected cases of NPC worldwide, 80% are from China. The present study investigates the effect of tanshinone IIA on the migration and invasion potential of HNE-1NPC cells and studied the detailed mechanism involved. Effect of the tanshinone IIA on viability of the HNE 1NPC cells was analyzed by MTS assay. Cell matrigel invasion and wound-healing motility assays, respectively were used for the analysis of invasion and migration potential of HNE-1 cells. Tanshinone IIA inhibited the viability of HNE 1cells in a dose dependent manner. Migration and invasion potential of the tanshinone IIA treated cells was reduced significantly (P < 0.05) compared to the control cells after 48 h. Analysis of the proteins involved in migration and invasion revealed a significant decrease in the expression of matrix metalloproteinase (MMP)-2 and MMP-9 on treatment with tanshinone IIA. It also inhibited the p65 and p50 expression in the nuclear fractions of HNE-1 cells after 48 h. Thus, tanshinone IIA inhibits migration and invasion potential of the HNE-1NPC cells through reduction in the expression of matrix metalloproteinases. Therefore, tanshinone IIA can be used for the treatment of NPC.

AB - An efficient micropropagation protocol was developed for Ruta graveolens Linn. using shoot tip meristems derived from a 4-month-old field grown plant. In vitro shoot regeneration and proliferation was accomplished on Murashige and Skoogs (MS) semi-solid medium in addition to different doses of cytokinins viz.6- benzyl adenine (BA), Kinetin (Kn) or 2-isopetynyl adenine (2iP), singly or in combination with auxins viz. indole-3-acetic acid (IAA), indole-3-butyric acid (IBA) or alpha-naphthalene acetic acid (NAA). Highest regeneration frequency (27.6%) was obtained on (MS) medium composed of BA (10 uM) with maximum number (9.4) of shoots and 4.3 cm shoot length after 4 weeks of incubation. Among various combinations tried best regeneration frequency (71%) of multiple shoot formation with highest number (12.6) of shoots per shoot tip explants were achieved in MS medium augmented with a combination BA (10.0 uM) and NAA (2.5 uM) after 4 weeks of incubation. The optimum frequency (97%) of rhizogenesis was achieved on half-strength MS medium having 0.5 uM IBA after 4 weeks of incubation. Tissue culture raised plantlets with 5-7 fully opened leaves with healthy root system were successfully acclimatized off in SoilriteTM with 80% survival rate followed by transportation to normal soil under natural light. Genetic stability among in vitro raised progeny was evaluated by ISSR and RAPD markers. The entire banding pattern revealed from in vitro regenerated plants was monomorphic to the donor. The present protocol provides an alternative option for commercial propagation and fruitful setting up of genetically uniform progeny for sustainable utilization and germplasm preservation.

AB - Potassium bromate (KBrO3) is widely used as a food additive and is a major water disinfection by-product. The present study reports the side effects of KBrO3 administration in Swiss mice. Animals were randomly divided into three groups: control, low dose KBrO3 (100 mg/kg/day) and high dose KBrO3 (200 mg/kg/day) groups. Administration of KBrO3 led to decreased white blood corpuscles (WBCs), red blood corpuscles (RBCs) and platelets count in the animals of both the high and the low dose groups. Altered lipid profile represented as low density lipoprotein (LDL), high density lipoprotein (HDL) and cholesterol levels were observed in plasma samples of both KBrO3 treated groups of mice. Also, an increased plasma level of LDH was detected in both KBrO3 treated groups. Histological investigations showed impaired renal and hepatic histology that was concomitant with increased plasma Creatinine level in both of KBrO3-treated groups. Nevertheless, decreased glutathione (GSH) level in both renal and hepatic tissue of mice after KBrO3 intake was detected. These results show that KBrO3 has serious damaging effects and therefore, its use should be avoided. PMID- 29472780 TI - Conservation in Saudi Arabia; moving from strategy to practice. AB - Conservation in the Kingdom of Saudi Arabia is relatively young, yet have made considerable gains in conservation through strategic proclamation and reintroductions. Changes in land use, illegal hunting and competition with domestic stock has decimated the native ungulates, meaning that the survival of the native ungulate species is now completely dependent on protected area network. The challenge is to sustain this network to make meaningful conservation impact into the future. We review the status of ungulate conservation in Saudi Arabia and highlight that the conservation strategy is well developed. The major challenge faced in conservation in Saudi Arabia now is to implement what has been sanctioned. PMID- 29472779 TI - Effect of PEG-6000 imposed drought stress on RNA content, relative water content (RWC), and chlorophyll content in peanut leaves and roots. AB - Drought, one of the environmental stresses, plays crucial role in reduction in plant production on majority of agricultural fields of world, In order to evaluate drought stress on RNA content Relative water content (RWC), and chlorophyll content, Water deficit was induced by Polyethylene glycol (PEG) in peanut (Arachis hypogaea), accession number ICGV 91114. In this current study we evaluate RNA content and Relative water content (RWC) both in leaves and roots and chlorophyll content in leaf. The present study was undertaken with the aim to investigate the effect of water deficit imposed by PEG-6000, 40 old day seedlings were treated with varying concentrations of polyethylene glycol-6000 (PEG-6000; w/v-5%, 10%, 15% & 20%) for 24 h. The results showed that RNA content and Relative water content (RWC) content was significantly reduced in both leaves and roots with increased concentration of PEG, In leaves, a concentration dependent decline in chlorophyll content with increasing concentration of polyethylene glycol-6000 (PEG-6000). Reduction in chlorophyll 'a' level was to a greater extent than the chlorophyll 'b'. Thus, this attributes can be used as screening tool for drought tolerance in peanut. PMID- 29472781 TI - Evaluation of traditional medicinal plant, Cissus setosa Roxb. (Vitaceae) for antiulcer property. AB - Cissus setosa is an indigenous medicinal herb commonly used for the treatment of gastro ulcers. In the current investigation the aerial methanolic extract of C. setosa was investigated for their antiulcer activity using pylorus ligation and ethanol in experimental rats. The extract was administered at the doses of 200 and 400 mg/kg b.w. orally for 3 days. However, higher dose of the extract subsequently reduced gastric ulcer induced aberrations by pylorus ligation (70.05%) and ethanol (78.16%) as judged by their altered biochemical parameters such as free acidity, total acidity, total carbohydrate, total protein and pepsin activity. Furthermore, macroscopic examination of rat's stomach also showed that the pretreatment with methanolic extract notably lowered the pylorus ligation and ethanol induced ulcers. As perceived in the present study, evidently, our findings basically supports the potency of the methanol extracts of C. setosa to treat gastrointestinal related disorders, thus lends pharmacological credence to the suggested folklore use. PMID- 29472782 TI - Grafting improves cucumber water stress tolerance in Saudi Arabia. AB - Water scarcity is a major limiting factor for crop productivity in arid and semi arid areas. Grafting elite commercial cultivars onto selected vigorous rootstocks is considered as a useful strategy to alleviate the impact of environmental stresses. This study aims to investigate the feasibility of using grafting to improve fruit yield and quality of cucumber under water stress conditions. Alosama F1 cucumber cultivar (Cucumis sativus L.) was grafted onto Affyne (Cucumis sativus L.) and Shintoza A90 (Cucurbitamaxima * C. moschata) rootstocks. Non-grafted plants were used as control. All genotypes were grown under three surface drip irrigation regimes: 50%, 75% and 100% of the crop evapotranspiration (ETc), which represent high-water stress, moderate-water stress and non-water stress conditions, respectively. Yield and fruit quality traits were analyzed and assessed. In comparison to the non-grafted plants, the best grafting treatment under water stress was Alosama F1 grafted onto Shintoza A90 rootstock. It had an overall improved yield and fruit quality under water stress owing to an increase in the total fruit yield by 27%, from 4.815 kg plant-1 in non-grafted treatment to 6.149 kg plant-1 in grafted treatment under moderate -water stress, total soluble solid contents (13%), titratable acidity (39%) and vitamin C (33%). The soil water contents were low in soil surface and increase gradually with soil depth, while salt distribution showed an adverse trend. The positive effects of grafting on plant growth, productivity, and water use efficiency support this strategy as an useful tool for improving water stress tolerance in greenhouse grown cucumber in Saudi Arabia. PMID- 29472783 TI - Performance evaluation of Chrysopogon zizanoides under urban conditions of Kuwait. AB - Plant physiological and morphological attributes should be critically evaluated for selecting any species for landscaping projects. The selection of a species should be based on the evaluation of its adaptability, noninvasiveness, growth potential, and performance under the prevailing local arid conditions for their aesthetic looks, soil stabilization, and afforestation values. Chrysopogon zizanoides (Vetiver), is suitable for Kuwait because it can withstand fluctuating temperatures ranging from -14 to 55 degrees C with unique physical and physiological characteristics. Despite the successful growth performance of Vetiver in landscaping projects mostly in several tropical countries, it has not been utilized and evaluated in the Arabian Gulf region. The objective of the current study was to evaluate the performance of selected ten cultivars of Vetiver (ODV-1, 8, 9, 13, 17, 21, 23, Silent Valley, Urlikal, and Pannimedu) in the deficient soil and environmental conditions of Kuwait in urban landscape at minimal maintenance. It is suggested that based on visual greenery effect and overall growth performance cultivars, Pannimedu, Silent Valley, ODV-13, ODV-8 and ODV-9 can be considered for landscaping projects in Kuwait. To obtain the superior crown volume (which considers height and canopy) cultivar Pannimedu is suggested and to get a bushy growth (considering the number of tillers) cultivar ODV-13 and ODV-8 is found to be suitable. PMID- 29472784 TI - Preparation, characterization of silver phyto nanoparticles and their impact on growth potential of Lupinus termis L. seedlings. AB - The current study reports rapid and easy method for synthesis of eco-friendly silver nanoparticles (AgNPs) using Coriandrum sativum leaves extract as a reducing and covering agent. The bio-reductive synthesis of AgNPs was monitored using a scanning double beam UV-vis spectrophotometer. Transmission electron microscopy (TEM) was used to characterize the morphology of AgNPs obtained from plant extracts. X-ray diffraction (XRD) patterns of AgNPs indicate that the structure of AgNPs is the face centered cubic structure of metallic silver. The surface morphology and topography of the AgNPs were examined by scanning electron microscopy and the energy dispersive spectrum revealed the presence of elemental silver in the sample. The silver phyto nanoparticles were collected from plant extract and tested growth potential and metabolic pattern in (Lupinus termis L.) seedlings upon exposure to different concentrations of AgNPs. The seedlings were exposed to various concentrations of (0, 0.1, 0.3 and 0.5 mg L-1) AgNPs for ten days. Significant reduction in shoot and root elongation, shoot and root fresh weights, total chlorophyll and total protein contents were observed under the higher concentrations of AgNPs. Exposure to 0.5 mg L-1 of AgNPs decreased sugar contents and caused significant foliar proline accumulation which considered as an indicator of the stressful effect of AgNPs on seedlings. AgNPs exposure resulted in a dose dependent decrease in different growth parameters and also caused metabolic disorders as evidenced by decreased carbohydrates and protein contents. Further studies needed to find out the efficacy, longevity and toxicity of AgNPs toward photosynthetic system and antioxidant parameters to improve the current investigation.

The objective of the current study was to transfer this sort of precious knowledge from old members of the community to young generations in documented form. PMID- 29472785 TI - Honey: Single food stuff comprises many drugs. AB - Honey is a natural food item produced by honey bees. Ancient civilizations considered honey as a God gifted prestigious product. Therefore, a huge literature is available regarding honey importance in almost all religions. Physically, honey is a viscous and jelly material having no specific color. Chemically, honey is a complex blend of many organic and inorganic compounds such as sugars, proteins, organic acids, pigments, minerals, and many other elements. Honey use as a therapeutic agent is as old as human civilization itself. Prior to the appearance of present day drugs, honey was conventionally used for treating many diseases. At this instant, the modern research has proven the medicinal importance of honey. It has broad spectrum anti-biotic, anti-viral and anti fungal activities. Honey prevents and kills microbes through different mechanism such as elevated pH and enzyme activities. Till now, no synthetic compound that works as anti-bacterial, anti-viral and anti-fungal drugs has been reported in honey yet it works against bacteria, viruses and fungi while no anti-protozoal activity has been reported. Potent anti-oxidant, anti-inflammatory and anti cancerous activities of honey have been reported. Honey is not only significant as anti-inflammatory drug that relieve inflammation but also protect liver by degenerative effects of synthetic anti-inflammatory drugs. This article reviews physico-chemical properties, traditional use of honey as medicine and mechanism of action of honey in the light of modern scientific medicinal knowledge.

AB - Drying of garlic slices in thin-layer have been studied with Infrared (IR) at 0.075, 0.15, 0.225 and 0.3 W cm-2 radiation intensity and 0.75 and 1.25 m s-1 air flow velocity. The results showed increasing in drying rate and decreasing at the time of drying with decreasing air flow velocity and increasing IR radiation intensity. The effective moisture diffusivity (Deff) was obtained using Fick's diffusion equation and its mean values ranged between 5.83*10-11 and 7.66*10-10 m2 s-1 for all investigated conditions. In addition, a third-order polynomial equation linking the effective moisture diffusivity and moisture content was found. Average activation energy increased with the decrease of IR radiation and increase of air flow velocity. Thirteen different mathematical models were verified with non-linear regression analysis for describing the garlic drying process. Modified Henderson and Pabis model presented the best prediction of the drying of garlic slices. PMID- 29472788 TI - Impact of pH and butyric acid on butanol production during batch fermentation using a new local isolate of Clostridium acetobutylicum YM1. AB - The effect of pH and butyric acid supplementation on the production of butanol by a new local isolate of Clostridium acetobutylicum YM1 during batch culture fermentation was investigated. The results showed that pH had a significant effect on bacterial growth and butanol yield and productivity. The optimal initial pH that maximized butanol production was pH 6.0 +/- 0.2. Controlled pH was found to be unsuitable for butanol production in strain YM1, while the uncontrolled pH condition with an initial pH of 6.0 +/- 0.2 was suitable for bacterial growth, butanol yield and productivity. The maximum butanol concentration of 13.5 +/- 1.42 g/L was obtained from cultures grown under the uncontrolled pH condition, resulting in a butanol yield (YP/S ) and productivity of 0.27 g/g and 0.188 g/L h, respectively. Supplementation of the pH-controlled cultures with 4.0 g/L butyric acid did not improve butanol production; however, supplementation of the uncontrolled pH cultures resulted in high butanol concentrations, yield and productivity (16.50 +/- 0.8 g/L, 0.345 g/g and 0.163 g/L h, respectively). pH influenced the activity of NADH-dependent butanol dehydrogenase, with the highest activity obtained under the uncontrolled pH condition. This study revealed that pH is a very important factor in butanol fermentation by C. acetobutylicum YM1. PMID- 29472789 TI - Effect of different proportion of sulphur treatments on the contents of glucosinolate in kale (Brassica oleracea var. acephala) commonly consumed in Republic of Korea. AB - Kale (Brassica oleracea L. Acephala Group) is the rich source of medicinal value sulphur compounds, glucosinolates (GLSs). The aim of this study was to investigate the effect of different proportion of sulphur (S) supplementation levels on the accumulation of GLSs in the leaves of the kale cultivar ('TBC'). High performance liquid chromatography (HPLC) separation method guided to identify and quantify six GSLs including three aliphatic (progoitrin, sinigrin and gluconapin) and three indolyl (glucobrassicin, 4-methoxyglucobrassicin and neoglucobrasscin) respectively. Analysis of these distinct levels of S supplementation revealed that the accumulation of individual and total GLSs was directly proportional to the S concentration. The maximum levels of total GLSs (26.8 umol/g DW) and glucobrassicin (9.98 umol/g DW) were found in lower and upper parts of the leaves supplemented with 1 mM and 2 mM S, respectively. Interestingly, aliphatic GSLs were noted predominant in all the parts (50.1, 59.3 and 56% of total GSLs). Among the aliphatic and indolyl GSLs, sinigrin and glucobrassicin account 35.3 and 30.88% of the total GSLs. From this study, it is concluded that supply of S enhance the GSLs accumulation in kale. PMID- 29472790 TI - Pollen morphology of certain species of the family Lamiaceae in Saudi Arabia. AB - The intention of the present wok is to provide an account on the pollen morphological features of Lamiaceae in Saudi Arabia as a basis for future studies of Lamiaceae pollens in the region. Pollen morphology of 20 species belong to 16 genera of the Lamiaceae has been investigated using Light Microscope (LM) and Scanning Electron Microscope (SEM). The study revealed that the pollen grains were characterized by 3-zonocolpate or 6-zonocolpate. Size of the pollen is variable between the genera but not among the species of the same genus. The surface pattern of the exine varies from fine reticulate, rough reticulate, mega reticulate, reticulate-perforate, bireticulate-perforate or granulate, leading to 6 types of pollen grains. These variations revealed by this study implies that pollen Morphology may be of significant value sharing in solving problems in the classification of Lamiaceae members. A Key to the species, based on the morphological features of pollen grains, is also provided. PMID- 29472791 TI - Antimicrobial activity of some plant extracts against bacterial strains causing food poisoning diseases. AB - Prevention of food spoilage and food poisoning pathogens is usually achieved by use of chemical preservatives which have negative impacts including: human health hazards of the chemical applications, chemical residues in food & feed chains and acquisition of microbial resistance to the used chemicals. Because of such concerns, the necessity to find a potentially effective, healthy safer and natural alternative preservatives is increased. Within these texts, Plant extracts have been used to control food poisoning diseases and preserve foodstuff. Antimicrobial activity of five plant extracts were investigated against Bacillus cereus, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Salmonella typhi using agar disc diffusion technique. Ethanolic extracts of Punica granatum, Syzygium aromaticum, Zingiber officinales and Thymus vulgaris were potentially effective with variable efficiency against the tested bacterial strains at concentration of 10 mg/ml while extract of Cuminum cyminum was only effective against S. aureus respectively. P. granatum and S. aromaticum ethanolic extracts were the most effective plant extracts and showed bacteriostatic and bactericidal activities against the highly susceptible strains of food borne pathogenic bacteria (S. aureus and P. aeruginosa) with MIC's ranged from 2.5 to 5.0 mg/ml and MBC of 5.0 and 10 mg/ml except P. aeruginosa which was less sensitive and its MBC reached to 12.5 mg/ml of S. aromaticum respectively. These plant extracts which proved to be potentially effective can be used as natural alternative preventives to control food poisoning diseases and preserve food stuff avoiding healthy hazards of chemically antimicrobial agent applications. PMID- 29472792 TI - Can clusters based on caries experience and medical status explain the distribution of overhanging dental restorations and recurrent caries? A cross sectional study in Madinah - Saudi Arabia. AB - Background: Overhanging dental restorations (ODRs) and secondary caries lesions (SCLs) are of high prevalence and jeopardize the fate of the restoration. Objectives: To assess the relationship between ODRs, SCLs and certain caries contributory factors. Methods: A total of 502 radiographic records of dental patients with proximal fillings (mean age 38 +/- 13 years, 50% females) were screened for ODRs and SCLs. Descriptive and inferential statistics were used. In addition, two-step cluster analysis was performed in an attempt to explain trends in ODR and SCL distribution. A p value of <= 0.05 was considered statistically significant. Results: More than 30% of the individuals had ODRs and SCLs. No differences between genders were observed (p > 0.05). Individuals with medical conditions had more ODRs than those without (49% vs. 34%, p <= 0.05), while those with high caries experience had more SCLs (49%, p <= 0.05). The cluster analysis grouped the participants in five clusters, with the cluster involving individuals with no medical conditions and low caries experience demonstrating the lowest prevalence of ODRs and SCLs. Conclusions: Within the study limits, more than one third of the sample of dental patients had ODRs and SCLs. The medical condition was associated with ODRs, while the past caries experience was associated with SCLs. PMID- 29472793 TI - Dihydroartemisinin inhibits colon cancer cell viability by inducing apoptosis through up-regulation of PPARgamma expression. AB - The present study was aimed to investigate the effect of dihydroartemisinin on the colon cancer cell proliferation and apoptosis. The results from MTT assay revealed a concentration and time dependent relation between the inhibition of SW 948 cell viability and dihydroartemisinin addition. The viability of SW 948 cells was reduced to 45 and 24% on treatment with 30 and 50 uM, respectively concentrations of dihydroartemisinin after 48 h. Morphological examination of SW 948 cells showed attainment of rounded shape and cluster formation on treatment with dihydroartemisinin. Western blot analysis showed a significant increase in the activation of caspase-3 and expression of cleaved PARP by dihydroartemisinin treatment. The activation of PPARgamma was increased significantly in SW 948 cells by treatment with dihydroartemisinin. Compared to control, the migration potential of SW 948 cells was reduced significantly (p < 0.005) and the expression levels of MMP-2 and -9 inhibited by dihydroartemisinin at 50 uM concentration. In the dihydroartemisinin treatment group colon tumor formation was significantly inhibited on treatment with 20 mg/kg doses of dihydroartemisinin after 30 days. Therefore, dihydroartemisinin inhibits colon cancer growth by inducing apoptosis and increasing the expression of PPARgamma. Thus dihydroartemisinin can be used for the treatment of colon cancer. PMID- 29472794 TI - Validation of botanical origins and geographical sources of some Saudi honeys using ultraviolet spectroscopy and chemometric analysis. AB - This study aims at distinguishing honey based on botanical and geographical sources. Different floral honey samples were collected from diverse geographical locations of Saudi Arabia. UV spectroscopy in combination with chemometric analysis including Hierarchical Cluster Analysis (HCA), Principal Component Analysis (PCA), and Soft Independent Modeling of Class Analogy (SIMCA) were used to classify honey samples. HCA and PCA presented the initial clustering pattern to differentiate between botanical as well as geographical sources. The SIMCA model clearly separated the Ziziphus sp. and other monofloral honey samples based on different locations and botanical sources. The results successfully discriminated the honey samples of different botanical and geographical sources validating the segregation observed using few physicochemical parameters that are regularly used for discrimination. PMID- 29472795 TI - Effect of gut bacterial isolates from Apis mellifera jemenitica on Paenibacillus larvae infected bee larvae. AB - The probiotic effects of seven newly isolated gut bacteria, from the indegenous honey bees of Saudi Arabia were investigated. In vivo bioassays were used to investigate the effects of each gut bacterium namely, Fructobacillus fructosus (T1), Proteus mirabilis (T2), Bacillus licheniformis (T3), Lactobacillus kunkeei (T4), Bacillus subtilis (T5), Enterobacter kobei (T6), and Morganella morganii (T7) on mortality percentage of honey bee larvae infected with P. larvae spores along with negative control (normal diet) and positive control (normal diet spiked with P. larvae spores). Addition of gut bacteria to the normal diet significantly reduced the mortality percentage of the treated groups. Mortality percentage in all treated groups ranged from 56.67% up to 86.67%. T6 treated group exhibited the highest mortality (86.67%), whereas T4 group showed the lowest mortality (56.67%). Among the seven gut bacterial treatments, T4 and T3 decreased the mortality 56.67% and 66.67%, respectively, whereas, for T2, T6, and T7 the mortality percentage was equal to that of the positive control (86.67%). Mortality percentages in infected larval groups treated with T1, and T5 were 78.33% and 73.33% respectively. Most of the mortality occurred in the treated larvae during days 2 and 3. Treatments T3 and T4 treatments showed positive effects and reduced mortality. PMID- 29472796 TI - Characterization of gut bacterial flora of Apis mellifera from north-west Pakistan. AB - Gut microbiota has been recognized to play a beneficial role in honey bees (Apis mellifera). Present study was designed to characterize the gut bacterial flora of honey bees in north-west Pakistan. Total 150 aerobic and facultative anaerobic bacteria from guts of 45 worker bees were characterized using biochemical assays and 16S rDNA sequencing followed by bioinformatics analysis. The gut isolates were classified into three bacterial phyla of Firmicutes (60%), Proteobacteria (26%) and Actinobacteria (14%). Most of the isolates belonged to genera and families of Staphylococcus, Bacillus, Enterococcus, Ochrobactrum, Sphingomonas, Ralstonia, Enterobacteriaceae, Corynebacterium and Micrococcineae. Many of these bacteria were tolerant to acidic environments and fermented sugars, hence considered beneficial gut inhabitants and involved the maintenance of a healthy microbiota. However, several opportunistic commensals that proliferate in the hive environment including members Staphylococcus haemolyticus group and Sphingomonas paucimobilis were also identified. This is the first report on bee gut microbiota from north-west Pakistan geographically situated at the crossroads of Indian subcontinent and central Asia.

AB - Owing to white meat production Labeo rohita have vast economic importance, but its population has been reduced drastically in River Chenab due to pollution. Atomic absorption spectrophotometry showed a merciless toxicity level of Cd, Cu, Mn, Zn, Pb, Cr, Sn and Hg. Comet assay results indicated significant (p < .05) DNA fragmentation in Labeo rohita as 42.21 +/- 2.06%, 31.26 +/- 2.41% and 21.84 +/- 2.21% DNA in comet tail, tail moment as 17.71 +/- 1.79, 10.30 +/- 1.78 and 7.81 +/- 1.56, olive moment as 13.58 +/- 1.306, 8.10 +/- 1.04 and 5.88 +/- 0.06, respectively, from three different polluted sites on the river. Micronucleus assay showed similar findings of single micronucleus induction (MN) as 50.00 +/- 6.300/00, double MN 14.40 +/- 2.560/00, while nuclear abnormalities (NA) were found as 150.00 +/- 2.920/00. These higher frequencies of MN induction and NA were found to be the cause of reduction of 96% of the population of this fish species in an experimental area of the River Chenab. This fish species has been found near extinction through the length of the river Chenab and few specimens in rainy seasons if restored by flood, may die in sugarcane mill season. Due to sweeping extinction Labeo rohita showed the highest sensitivity for pollution and could be used as bioindicator and DNA fragmentation in this column feeder fish species as a biomarker of the pollution load in freshwater bodies. PMID- 29472798 TI - Plankton community and the relationship with the environment in saline lakes of Onon-Torey plain, Northeastern Mongolia. AB - The plankton community of sixteen saline lakes located on Onon-Torey plain (Northeastern Mongolia) during the filling phase and the raising of the water level was investigated in July 2011. Thirty-five taxa of phytoplankton and thirty one species of zooplankton were found. For phytoplankton, blue-green algae (Merismopedia elegans, Anabaenopsis elenkinii, Arthrospora fusiformis, Spirulina major, Lyngbya sp., Oscillatoria sp.) and green algae (Monoraphidium minutum, Tetrastrum komarekii, Ankyra ocellata, Oocystis sp.) were dominant. For zooplankton, Filinia longiseta, Brachionus plicatilis, B. variabilis, Hexarthra mira (Rotifera), Daphnia magna, Moina brachiata, M. mongolica (Cladocera), Arctodiaptomus bacillifer, Mixodiaptomus incrassatus, Metadiaptomus asiaticus (Copepoda) dominated. Mineralization, active hydrogen ratio, dissolved oxygen and water temperature were the main factors influencing the diversity, structure and distribution of plankton organisms in the steppe lakes during low water level. The RDA analysis for phytoplankton and zooplankton from different lakes was carried out for selected two groups which included lakes and a subset related species. The first group is of oligohaline and mesohaline lakes in which mostly green algae, rotifers and copepods inhabit. The second group is of mesohaline and polyhaline lakes with mainly blue-green algae, some crustaceans and rotifers inhabiting. High abundance and biomass of Spirulina major, Oscillatoria sp. and Brachionus variabilis were observed in lakes with high mineralization, pH and temperature.

AB - Introduction: The aim of the IMPACT (IMProving Access to Clinical Trial data) Observatory is to assess the transformation of clinical trials (CT) related to the evolution of sharing of CT data. The objective of this study is to establish a baseline for monitoring CT data sharing by the Observatory. Materials and methods: In this scoping review we searched for publications that address sharing, dissemination, transparency or reuse of CT data published prior to December 31st 2000. Two authors screened titles and abstracts of 1204 records received by Medline searches and added 47 publications from direct discovery. Four researchers extracted, coded, and analyzed the predefined information from 102 selected papers. Results: We found a growing recognition of the importance of data sharing prior to 2001. However, there were numerous obstacles including the ambiguity of the concept of data sharing, the absence of specific terminology and the lack of an "open" culture. By the end of 2000, data, metadata, and evidence based medicine were defined. Data sharing, registries, databases and re-analyses of individual patient data (IPD) emerged. The use of systematic reviews and IPD meta-analysis in decision making was promoted. Most arguments for broader data sharing came from oncology, paediatrics, rare diseases, AIDS, pregnancy, perinatal medicine, and media reporting related scandals. Conclusions: Our findings indicate that the year 2000 could be used as a baseline for monitoring the evolution of CT data sharing as basic prerequisites were set in place, including greater understanding that CT data sharing is essential for decision making and the advancements of the Internet. PMID- 29472801 TI - Diagnostic value of tumour markers in pleural effusions. AB - Introduction: We investigated whether tumour markers carcinoembryonic antigen (CEA), neuron-specific enolase (NSE), cancer antigen 125 (CA-125), and cytokeratin 19 fragment (CYFRA 21-1) in pleural effusions and serum can be used to distinguish pleural effusion aetiology. Materials and methods: During the first thoracentesis, we measured pleural fluid and serum tumour marker concentrations and calculated the pleural fluid/serum ratio for patients diagnosed with pleural effusion, using electrochemiluminescence immunoassays. Receiver operating characteristic (ROC) analysis was carried out and the Hanley and McNeil method was used to test the significance of the difference between the areas under ROC curves (AUCs). In order to detect which tumour marker best discriminates between malignant and non-malignant pleural effusions and to establish the predictive value of those markers, discriminant function analysis (DFA) and logistic regression analysis were utilized. Results: Serum tumour markers CYFRA 21-1 and NSE as well as pleural NSE were good predictors of pleural effusion malignancy and their combined model was found statistically significant (Chi-square = 28.415, P < 0.001). Respective ROC analysis showed significant discrimination value of the combination of these three markers (AUC = 0.79). Conclusions: Serum markers showed superiority to pleural fluid markers in determining pleural fluid aetiology. Serum CYFRA 21-1 and NSE concentrations as well as pleural fluid NSE values had the highest clinical value in differentiating between malignant and non-malignant pleural effusions. The combination of these three markers produced a significant model to resolve pleural effusion aetiology.

AB - Introduction: Laboratories often modify procedures recommended by the European Urinalysis Guidelines for urine sediment analysis. The aim of this study was to compare the recommended protocol with our routine laboratory procedure and to evaluate the possible impact of modifications in the relative centrifugal force, type of tube, method of supernatant aspiration and urine volume on patient's results. Material and methods: Firstly, relative centrifugal force was investigated using 20 pairs of samples examined after centrifugation at 400xg and 1358xg. In phase two, 110 samples were examined, paired as: round bottom vs conical tube (N = 46), decanting vs suction of supernatant (N = 100) and 10 mL vs 5 mL of urine sample (N = 101). Results: The number of erythrocytes, leukocytes and squamous epithelial cells was significantly lower after centrifugation at 400xg (P = 0.001, 0.002 and 0.004, respectively). The number of leukocytes was significantly lower in conical tubes (P = 0.010), after the suction of supernatant (P = 0.045) and in 5 mL urine (P < 0.001). The number of squamous epithelial cells was significantly lower after the suction of supernatant (P < 0.001) and in 5 mL urine (P < 0.001). The number of erythrocytes (P < 0.001), total non-hyaline casts (P < 0.001) and the frequency of granular casts (P = 0.039) was significantly lower in 5 mL urine. Conclusion: Lower results of leukocytes, erythrocytes, squamous cells and non-hyaline casts were recorded in recommended procedures (centrifugation at 400xg, suction of supernatant, conical tube, 5 mL of sample) than in routine procedure (centrifugation at 1358xg, decanting of supernatant, round bottom tube, 10 mL) used in our laboratory. PMID- 29472803 TI - Reference interval for immature platelet fraction on Sysmex XN haematology analyser in adult population. AB - Introduction: The Sysmex XN-series haematology analyser has newly adopted a fluorescent channel to measure immature platelet fraction (IPF). To promote the clinical utility of this promising parameter, establishing a reliable reference interval is mandatory. According to previous studies, IPF values may be affected by the employed analyser and the ethnic background of the individual, but no differences seem to be found between individuals' genders. Therefore, this study aimed to define the reference interval for IPF in a Spanish population following Clinical and Laboratory Standard Institute (CLSI) guidelines. Materials and methods: A total of 153 healthy Caucasian adults from Spain met the inclusion criteria. IPF measurement was performed by means of a Sysmex XN-2000 haematology analyser. A non-parametric percentile method was used to calculate the reference intervals in accordance with CLSI guidelines. Results: The obtained reference interval for IPF on the Sysmex XN-2000 was 1.6-9.6% (90% confidence intervals (CIs) were 1.5-1.8 and 9.3-11.5, respectively). No significant gender difference in IPF reference intervals was observed (P = 0.101). Conclusions: This study provides, for the first time, a reference interval for IPF using a Sysmex XN-2000 in a Spanish population, ranging from 1.6 to 9.6%. These data are needed to evaluate platelet production in several conditions such as thrombocytopenia, inflammatory states and cardiovascular diseases, as well as for future research. PMID- 29472804 TI - Henoch-Schonlein purpura in the third trimester of pregnancy. AB - Henoch-Schonlein purpura (HSP) is an IgA-mediated small vessels' vasculitis that affects the skin, intestines and kidneys. Pregnancy has been reported as an exacerbating factor. We present the case of a 24-year-old primigravida with HSP that occurred in the third trimester and lasted up to the end of the successful delivery. She had pruritic maculopapular exanthema on her legs. Biopsy of a cutaneous lesion was performed for histopathologic features and direct immunofluorescence (DIF) for the presence of perivascular IgA deposition. Histopathology of the cutaneous lesion confirmed leukocytoclastic vasculitis. A DIF examination of the skin lesion confirmed deposits of fibrinogen in the small blood vessel walls. Six weeks following delivery, the skin lesions almost completely disappeared. Control laboratory findings were normal. This case of HSP might have been primarily associated with a preceding respiratory infection but this should first be carefully investigated due to a possible severe immunological disease in the patient's background requiring special attention since nephrotic symptoms may occur. PMID- 29472805 TI - Gamma heavy-chain disease accompanied with follicular lymphoma: a case report. AB - Heavy chain diseases (HCD) are B-cell lymphoprolipherative disorders characterized by the production of monoclonal heavy chains without associated light chains. Some cases of gamma-HCD (gamma-HCD) are concurrent with other lymphoid neoplasm. The monoclonal component is not always detectable by serum electrophoresis, and often an immunofixation procedure is necessary to detect this component. Prognosis is variable, and no established guidelines for follow up are available. We describe a case of a challenging diagnosis of gamma-HCD due to the absence of clinical signs frequently reported in the disease (anaemia and palatal oedema among others). Haematological malignancy was the first suspicion but bone marrow examination was negative. In addition, the presence of an autoimmune bicytopenia and a Klinefelter syndrome complicated the clinical context of the patient. A thoracoabdominal computed tomography reported many small adenopathies whose pathological and immunohystochemical study revealed a follicular lymphoma. Shortly after, serum inmunofixation secondary to an abnormal electrophoretic pattern revealed a gamma paraprotein without light chains. Eventually, gamma-HCD in association with follicular lymphoma was the final diagnosis. This is the first case reporting this association. PMID- 29472806 TI - Neutrophil gelatinase-associated lipocalin and acute kidney injury in endovascular aneurysm repair or open aortic repair: a pilot study. AB - Introduction: Acute kidney injury (AKI) occurs frequently after abdominal aortic surgery and there is currently no effective marker able to detect early onset. The aim of this study is to evaluate the ability of neutrophil gelatinase associated lipocalin (NGAL) to early identify the development of acute renal damage in patients undergoing endovascular aneurysm repair (EVAR) or open aortic repair (OAR). Materials and methods: Serial samples of blood and urine were obtained from 25 patients undergoing both EVAR and OAR. Seven male subjects with AKI and 18 subjects with no-AKI (17 males, 1 female) were included in the study. We determined concentrations of serum creatinine (sCr) and urinary, serum and whole blood NGAL (uNGAL, sNGAL, bNGAL) collected at baseline, and after 4 and 18 hours. AKI was defined according to the RIFLE criteria (risk, injury, failure, loss of kidney function, and end-stage kidney disease): increase by 50% in sCr or reduction of at least 25% of estimated glomerular filtration rate (eGFR) from baseline. Results: Seven patients developed AKI in the stage Risk. There was no significant difference in sNGAL concentrations in the AKI group as compared to no AKI group. However, the uNGAL/uCreatinine ratio and bNGAL concentrations were significantly higher after 18 hours in the AKI group (no-AKI 1.69 (0.91 - 2.47) vs AKI 3.2 (2.08 - 5.92) ng/mg for uNGAL/uCreatinine ratio, P = 0.036; and no-AKI 83 (59 - 131) vs AKI 164 (126 - 263) ng/mL for bNGAL, P = 0.029). Conclusions: Our results suggest that uNGAL, sNGAL and bNGAL, after abdominal aortic surgery, are not suitable as early biomarkers of AKI. PMID- 29472807 TI - Elevated zinc concentrations in a 5 months old infant: A case report. AB - Pre-analytical errors account for the majority of laboratory-associated errors. In a 5 months old infant hospitalised with lung dysfunction due to prematurity, a routine measurement of zinc revealed an unexpected elevated concentration of 20.2 umol/L (reference interval 10.0 - 19.0 umol/L) compared to 11.6 umol/L five days earlier. Zinc measurement was repeated two days later and had further increased to 42.4 umol/L. Of note, there were no clinical signs of the increased zinc concentrations. Performance data for the zinc analysis (performed by inductively coupled plasma mass spectrometry) was found satisfactory. A thorough review of the patient's medication and nutrition supplements revealed no relevant zinc content. The blood was obtained through capillary blood sampling, and anything at the skin puncture site containing zinc could therefore potentially contribute to the elevated zinc results. It was investigated if any ointment containing zinc had been applied at the puncture site, which revealed that the mother had applied vitamin E ointment containing zinc-oxide at the infant's heel. A capillary sample obtained from the opposite heel, where no vitamin E ointment had been applied, revealed a zinc concentration of 14.3 umol/L. In conclusion, pre-analytical contamination with ointments must be considered in case of unexpected measurements from capillary blood. PMID- 29472808 TI - Pseudohyperkalemia - Potassium released from cells due to clotting and centrifugation - a case report. AB - Hyperkalemia is a potentially lethal condition. Pseudohyperkalemia should be always excluded before implementing treatment to prevent inappropriate cause of hypokalemia - equally a potentially lethal condition. Here we present a case report of a 62 year female with chronic myeloproliferative disorder, i.e. essential thrombocythemia. The laboratory test results for potassium concentration were 6.3 mmol/L, for platelet count 1305 x109/L and for leukocyte count 39.8 x109/L. This was due to a temporary drug withdrawal after a surgical intervention for gastric bleeding. Potassium concentration in lithium heparin plasma collected in a vacuum tube without gel separator and in whole blood syringe were 4.6 mmol/L and 3.4 mmol/L, respectively. It means that mechanical stress such as centrifugation can contribute to spurious hyperkalemia.?Prior to reporting unexpected hyperkalemia result, pseudohyperkalemia should always be considered by the laboratory. Such potassium results require investigation in case it is pseudohyperkalemia, which may be due to thrombocytosis and leukocytosis. In cases where thrombocytosis or leukocytosis exists, an interpretative comment indicating these conditions inserted with the results of the potassium concentration can increase awareness for more accurate patient care decisions. PMID- 29472809 TI - The decrease in number of splenic lymphocytes in mice fed Rhodiola kirilowii during pregnancy and lactation concerns mainly CD19+ and CD4+ cells. AB - In previous work we described the decline in the number of splenocytes of mice which during pregnancy and lactation were fed Rhodiola kirilowii. In this work we present the size of individual subpopulations of splenic lymphocytes in these mice. Experiments were performed on adult inbred female Balb/c mice, 8-9 weeks old, 20-22 g b.m., mated with adult males from the same strain. Females, from when the copulatory plug was noted up to the 28th day after delivery, were supplemented daily with lyophilized aqueous (RKW) or 50% hydro-ethanolic (RKW-A) extract (20 mg/kg b.m.) dissolved in distilled water. Then, mice were euthanized, spleens dissected, cells counted and the total numbers of CD3+, CD19+, CD4+, CD8+ and CD335+ splenic lymphocytes were evaluated by cytometry. The number of CD3+ lymphocytes per 1 g of splenic tissue was higher in RKW-A than in RKW spleens and did not differ from the control. The number of CD3+ lymphocytes in RKW spleens was lower than in the controls. The number of CD19+ and CD4+ cells was lower in both experimental groups than in the controls. The number of CD335+(NK) cells was lower in RKW spleens than in the control. PMID- 29472810 TI - Concentration of MMP-8 and IL-1beta in gingival crevicular fluid in patients with chronic and aggressive periodontitis. AB - Modern research confirms the role of inflammatory mediators in the pathomechanism of periodontal tissue destruction. The aim of the study was to determine concentrations of MMP-8 and IL-1beta in gingival crevicular fluid (GCF) in patients with advanced chronic and aggressive periodontitis. The authors measured the concentrations of the above inflammatory mediators in gingival crevicular fluid of deep pockets (PD >= 6 mm) and shallow pockets (PD 4-5 mm) in 33 patients with advanced chronic periodontitis and in 16 patients with aggressive periodontitis. The control group consisted of 16 individuals with healthy periodontium. In all patients levels of MMP-8 and IL-1beta in GCF were determined with the ELISA method. The study showed significantly higher concentrations of MMP-8 and IL-1beta in GCF of both deep and shallow pockets in patients with periodontitis compared to healthy subjects. No difference in concentrations of the tested mediators was observed with reference to diagnosis of aggressive periodontitis (AP) or chronic periodontitis (CP). PMID- 29472811 TI - The influence of KIR gene presence/absence polymorphisms on the development of periodontal disease in smokers and non-smokers. AB - Introduction: Periodontal diseases are highly prevalent inflammatory, multifactorial diseases. Smoking is one of the most important environmental risk factors for the development and severity of periodontal disease. Killer cell immunoglobulin-like receptors (KIRs) are members of the immunoglobulin (Ig) superfamily and play an essential role in the regulation of NK cell activity, allowing natural killer (NK) cells to sense and respond to human leukocyte antigen (HLA) class I. The aim of this study was to evaluate the influence of KIR gene presence/absence polymorphisms on the development of periodontal disease in smokers and non-smokers. Material and methods: This study enrolled 400 Caucasian subjects (age range 25-69 years) from the West Pomeranian region of Poland. The subjects were categorized into four subgroups (smoking and non-smoking patients with periodontal disease; smoking and non-smoking subjects without periodontal disease - control subjects). Results: The differences of KIR gene frequencies between non-smoking patients and non-smoking control subjects as well as smoking patients and control subjects were not statistically significant. In multivariate regression analysis advanced age of patients and smoking were independent factors associated with increased frequency of periodontal disease. Conclusions: The results of this study suggest that the main factor associated with increased risk of periodontal disease is smoking, whereas KIR presence/absence polymorphism is not a significant factor involved in the pathogenesis of periodontal disease. PMID- 29472812 TI - Levels of cytokines in drug hypersensitivity. AB - Introduction: Multiple drug intolerance is a serious complication of drug therapy and is an issue of allergology. The aim of the study was the investigation of cytokine status in patients with drug hypersensitivity and multiple drug hypersensitivity. Material and methods: 19 patients with multiple drug hypersensitivity, 34 patients with hypersensitivity to one drug, and 35 non allergic subjects were involved. Only women were included in the study. A multiplex assay of 27 cytokines and chemokines was performed using xMap technology (Human Cytokine Panel I by Bio-Rad). Results: Women with drug allergy revealed increased IL-2 levels (p < 0.05). In the case of the study of cytokine status in patients with multiple drug hypersensitivity, the new data revealed the prevalence of pro-inflammatory cytokine status with the participation of cytokines IL-17, IL-9, TNF-alpha, IP-10, and MIP-1. Conclusions: Various immune response arms Th2, Th17, as well as macrophages were the determining factors in the cytokine balance that was found in patients with multiple drug hypersensitivity. PMID- 29472813 TI - Can mean platelet volume and neutrophil-to-lymphocyte ratio be biomarkers of acute exacerbation of bronchiectasis in children? AB - Introduction: Bronchiectasis (BE) is a parenchymal lung disease evolving as a result of recurrent lung infections and chronic inflammation. Although it has been shown in adult studies that mean platelet volume (MPV) and neutrophil-to lymphocyte ratio (NLR) can be used as biomarkers of airway inflammation, knowledge is limited in the paediatric age group. The aim of our study is to investigate the potential of MPV and NLR as biomarkers that may indicate acute exacerbations of non-cystic fibrosis BE in children. Material and methods: Children with non-cystic fibrosis BE (n = 50), who were followed in the division of Paediatric Pulmonology of our hospital between June 2010 and July 2015, were involved in the present retrospective cross-sectional study. Haemogram values during acute exacerbations and non-exacerbation periods, and a control group were compared. Results: In children with bronchiectasis, the average leukocyte count (p < 0.001), platelet count (p = 0.018), absolute neutrophil count (p < 0.001), and NLR (p < 0.001) were higher, as expected, when compared with the control group. NLR values, in the period of acute exacerbation were significantly higher than the values of both the non-exacerbation periods (p = 0.02) and the control group (p < 0.001). In contrast, MPV values in the period of acute exacerbation did not exhibit a significant difference from those of non-exacerbation periods (p = 0.530) and the control group (p = 0.103). Conclusions: It was concluded that leukocyte count, platelet count, absolute neutrophil count, and NLR can be used to show chronic inflammation in BE, but only NLR and absolute neutrophil count can be used as biomarkers to show acute exacerbations. PMID- 29472814 TI - FcgammaRIIa defunctioning polymorphism in paediatric patients with renal allograft. AB - Introduction: Fc gamma receptor (FcgammaR) IIa is considered the most widely distributed of the three classes of Fc receptors, and it expresses an allelic polymorphism. This type of polymorphism may modify the immune response and may be an important factor for some diseases. The aim of the study reported herein was to evaluate the association between the FcgammaRIIa polymorphism and susceptibility to both end-stage renal disease (ESRD) and acute kidney graft rejection (AR) in children who have undergone renal transplantation. Material and methods: The study evaluated 70 children who had undergone transplantation and 60 healthy subjects. AR was observed in 25 children. Results: FcgammaRIIa genotypes and alleles were significantly different between transplantation patients and the control group. The assessment for FcgammaR of the groups in which AR was present showed that there was only a risk of having an acute rejection in homozygous genotype RR. Conclusions: FcgammaRIIa RR genotype and allele frequency was increased in paediatric renal transplant recipients. The present findings showed that FcgammaRIIa genotype may be related to ESRD disease susceptibility, and FcgammaRIIa polymorphisms seemed to affect AR. PMID- 29472815 TI - Angiogenesis modulation by exogenous antioxidants. AB - Co-operation of the endogenous and exogenous defense system maintains redox homeostasis and is essential for health. The endogenous defense system includes enzymatic (e.g. superoxide dismutase, catalase) and non-enzymatic, low molecular weight scavengers (e.g. glutathione, ascorbic acid). Pathogenesis of many serious diseases (e.g. cancer, ischemic heart disease) includes oxidative stress which can disturb angiogenesis, the process of formation of new blood vessels sprouting from the existing one. Antioxidants, through reduction of oxidative stress and influence on neovascularization, may modulate progress and results of therapy in those diseases where such processes play an important role. Herein the impact of exogenous antioxidants on angiogenesis and factors modulating this process is presented. Most synthetic antioxidants whose activity has been described (namely N-acetylcysteine, pentoxifylline, synthetic analogue of curcumin, synthetic analogue of epigallocatechin-3 gallate [EGCG], tripertenoids) exert an inhibitory effect on neovascularization. A similar effect was also exhibited by several natural origin antioxidants (e.g. resveratrol, EGCG), which suggests that their application in therapy might normalize excessive angiogenesis. Some natural origin antioxidants e.g. purple coneflower and preparations consisting of natural antioxidants such as Padma 28 and Immunal forte increase a too low baseline level of angiogenesis and decreases a too high level. These preparations exert a regulatory effect on and may normalize neovascularization. They can be used in the case of diseases associated with too low or too high angiogenesis. PMID- 29472816 TI - Disorders noticed during development of pancreatic cancer: potential opportunities for early and effective diagnostics and therapy. AB - Pancreatic cancer, with a total five-year survival rate below 5%, represents a disease with a high level of malignancy. Some of the pancreatic cancer bad prognosis factors are nutrition disorders. Malnutrition, neither recognized nor properly referred to by the healthcare system, leads to well-documented negative health consequences in hospitalized patients including their impaired immunity, delayed post-surgery wound healing, a high risk of infectious complications, morbidity and mortality. There are numerous factors contributing to the development of pancreatic cancer, including telomerases, inflammation, angiogenesis, epigenetics and genetics factors, miRNA, pancreatic cancer stem cells. On the basis of molecular analyses, it has been established that precursor injuries may trigger pancreatic cancer when added to genetic alterations. Perhaps, combination of few presently used methods, like signal transduction modulated by K-ras, STAT3 activation, HMGB1 releasing, presence of oxidative stress and free radicals secretion, genes for proangiogenic growth factors activation or tissue-specific miRNA genes expression - will solve the problem of inadequate diagnostics. PMID- 29472817 TI - Myeloid-derived suppressor cells in ovarian cancer: friend or foe? AB - Although previous decades contributed to major progress in targeted therapy of many malignancies, the treatment of gynaecological cancers remains a challenging task. In the evidence of rising cancer mortality, the search for new methods of treatment is a dire need. Exploring the mechanisms of interaction between tumour cells and host immune response may allow the introduction of new, effective therapies - not as toxic and far more efficient than conventional methods of cancer treatment. Epithelial ovarian cancer (EOC) is typically diagnosed at advanced stages. Its incidence and mortality rate is high. Powerful diagnostic tools for this kind of cancer are still under investigation. Multiple mechanisms existing in the ovarian tumour network create a specific immunosuppressive microenvironment, in which accumulation of myeloid-derived suppressor cells (MDSCs) may be a critical component for diagnosis and treatment. This review attempts to verify current knowledge on the role of MDSCs in EOC. PMID- 29472818 TI - The role of anti-citrullinated protein antibodies (ACPA) in the pathogenesis of rheumatoid arthritis. AB - The most specific autoimmunity known for rheumatoid arthritis (RA) is reflected by generation of anti-citrullinated protein antibodies (ACPA). Presence of ACPA in established RA is associated with disease severity, while generation of ACPA at early developmental phases of RA can have a strong predictive value for progressing to the full-blown disease. Hence, development of ACPA may be of crucial importance to the pathogenesis of RA. Therefore, a lot of effort has been put recently to investigate the feature of ACPA at early developmental stages of RA (before disease onset) and functional activities of these autoantibodies. Results of these studies enlarged the knowledge about the nature of ACPA, which is essential for planning the therapeutic or preventive strategies interfering with their development and pathogenic functions. In this review we describe recent evidence for a role of ACPA in the etiopathogenesis of RA and indicate key unresolved issues regarding ACPA biology that need to be clarified in the future. PMID- 29472819 TI - Butyrophilins: an important new element of resistance. AB - Butyrophilins belonging to the immunoglobulin superfamily are new immune system regulators because they are present on lymphocytes, dendritic cells, monocytes, macrophages, neutrophils and eosinophils, and they exert a stimulatory and (or) inhibitory effect on them. The role of butyrophilins is associated and results from their similarity to the regulatory B7 protein family involved in the modulation of immune phenomena. Butyrophilins are glycoproteins built of two extracellular immunoglobulin domains, stabilized with disulfide bonds: constant IgC, and variable IgV and a transmembrane region. Most of these proteins contain a conserved domain encoded by a single exon - B30.2, also referred to as PRYSPRY. In humans, the family of butyrophilins includes 7 butyrophilin proteins, 5 butyrophilin-like proteins and the SKINT-like factor. Butyrophilins have been also demonstrated to play a role in various infections, e.g. tuberculosis or diseases that include sarcoidosis, systemic lupus erythematosus, rheumatoid arthritis, genetic metabolic diseases, ulcerative colitis, cancer and kidney disease. PMID- 29472820 TI - Diagnostic difficulties in a patient with paroxysmal cold haemoglobinuria and acute kidney injury. AB - Paroxysmal cold haemoglobinuria (PCH) is a form of autoimmune haemolytic anaemia (AIHA) characterised by a sudden onset of haemoglobinuria, either spontaneously or following exposure to cold. In children, it is commonly seen following a viral illness or after immunisation. Diagnosis of PCH is confirmed by a positive Donath Landsteiner (DL) test in which biphasic haemolysins are detected. However, in a real clinical setting, the serological diagnosis of PCH is not always easy. PCH can cause tubular renal injury, which in turn can lead to renal impairment. We describe a case of a two-year-old boy who was admitted to the hospital with pallor, jaundice, dehydration, and dark urine. Two weeks before admission, the child had an upper respiratory tract infection. Laboratory tests showed severe anaemia (haemoglobin 4.5g/dl, haematocrit 11.5%, LDH 8525 U/l), hyperbilirubinaemia (104 MUmol/l), haemoglobinuria, and acute kidney injury: GFR 43.9 ml/min/1.73 m2 (grade 2 according to Acute Kidney Injury Network). The direct antiglobulin test was positive for C3c and C3d complement components. The diagnosis of PCH was confirmed by the presence of biphasic antibodies in a DL test on the third day of hospitalisation. The patient received supportive treatment. PMID- 29472821 TI - Thrombotic thrombocytopenic purpura in the course of systemic lupus erythematosus in a 15-year-old girl. AB - Systemic lupus erythematosus (SLE) concomitant with thrombotic thrombocytopenic purpura (TTP) in children is rarely diagnosed. We report a case of a 15-year-old girl with butterfly patch, generalized edema, leg pain, anemia (Hb 74 g/l), thrombocytopenia (5 x 109/l), schistocytes in peripheral blood smear, acute kidney injury (eGFR 27 ml/min/1.73 m2), proteinuria, and erythrocyturia. The direct Coombs test was positive, and warm antibodies (IgG) were detected on red blood cells. ANA in titer 1 : 2560, low serum C3 and C4 complement level, ADAMTS13 (a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13) activity < 4% and the presence of ADAMTS13 inhibitor were detected. In renal biopsy class IVA/V lupus nephritis was diagnosed. Her clinical symptoms fulfilled criteria for the diagnosis of SLE and the diagnosis of TTP. She was treated with intravenous methylprednisolone and cyclophosphamide 750 mg/1.73 m2/monthly for six months, followed by oral prednisone with azathioprine, chloroquine, and enalapril. The long-term clinical outcome was good. We report a case rare in adolescents, TTP related to SLE, which may suggest the need to test for ADAMTS13 activity and the presence of ADAMTS13 inhibitor in children with SLE and anemia, thrombocytopenia and rapid deterioration of renal function, to make the right therapeutic decisions. PMID- 29472822 TI - Presence of a single nucleotide polymorphism (RS3758581) in a boy with DRESS syndrome. AB - Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is a rare, potentially life-threatening, drug-induced hypersensitivity reaction that includes rash, hematologic abnormalities, lymphadenopathy, and internal organ involvement. The pathogenesis of DRESS syndrome is partially understood. Various medications have been described as the cause of DRESS syndrome. Phenytoin and allopurinol are the most commonly reported culprit drugs, although more than 50 drugs can induce DRESS syndrome. Members of the cytochrome P450 (CYP) superfamily are the most commonly involved enzymes in metabolism of drugs such as phenytoin. This case report addresses the influence of CYP2C9 genetic polymorphism (a single nucleotide polymorphism) on phenytoin drug metabolism, thereby causing DRESS syndrome. PMID- 29472823 TI - Clinical variability of chromosome 22q11.2 deletion syndrome. AB - 22q11.2 deletion syndrome (22q11.2 DS) is a disorder that has multiple symptoms and affects various organs and systems. Despite the great variability of clinical manifestations, common 22q11.2 DS includes congenital heart defect, immunodeficiency, characteristic facial features, palatal defects, developmental and/or learning disabilities, and hypocalcaemia. We present the cases of three patients with 22q11.2 DS that we have observed. Heart defects were revealed in all cases, and tetralogy of Fallot in one of them. Immune system disorders in these cases were highly variable and did not correlate with aplasia or hypoplasia of the thymus. Cleft palate was diagnosed only in one case. Characteristic facial features were presented in all cases but they were not significant and varied from subtle to mild. Developmental disability was presented by motor delays in two cases. Hypocalcaemia was revealed in one patient, and seizures were absent. Only one case completely fit CATCH-22 syndrome (cardiac defects, abnormal facies, thymic hypoplasia, cleft palate, and hypocalcaemia caused by22q11.2 deletion). The other cases had three out of the five main features, with some other, less significant signs also presented. In some cases, even just a few signs should be the reason for further examination to exclude 22q11.2 deletion syndrome. Currently, immunological disorders are not a significant determinant in the diagnosis of this syndrome, and timely correction of heart defects can reduce the number of recurrent respiratory infections. A multidisciplinary approach to the management of these patients and providing timely, complex medical care will prevent serious complications. PMID- 29472824 TI - Active Surveillance Use Among a Low-risk Prostate Cancer Population in a Large US Payer System: 17-Gene Genomic Prostate Score Versus Other Risk Stratification Methods. AB - Many men with low-risk prostate cancer (PCa) receive definitive treatment despite recommendations that have been informed by two large, randomized trials encouraging active surveillance (AS). We conducted a retrospective cohort study using the OptumTM Research Database (Eden Prairie, MN) of electronic health records and administrative claims data to assess AS use for patients tested with a 17-gene Genomic Prostate ScoreTM (GPS; Genomic Health, Redwood City, CA) assay and/or prostate magnetic resonance imaging (MRI). De-identified records were extracted on health plan members enrolled from June 2013 to June 2016 who had >=1 record of PCa (n 5 291,876). Inclusion criteria included age >=18 years, new diagnosis, American Urological Association low-risk PCa (stage T1-T2a, prostate specific antigen <=10 ng/mL, Gleason score 5 6), and clinical activity for at least 12 months before and after diagnosis. Data included baseline characteristics, use of GPS testing and/or MRI, and definitive procedures. GPS or MRI testing was performed in 17% of men (GPS, n 5 375, 4%; MRI, n 5 1174, 13%). AS use varied from a low of 43% for men who only underwent MRI to 89% for GPStested men who did not undergo MRI (P <.001). At 6-month follow-up, AS use was 31.0% higher (95% CI, 27.6%-34.5%; P <.001) for men receiving the GPS test only versus men who did not undergo GPS testing or MRI; the difference was 30.5% at 12 month follow-up. In a large US payer system, the GPS assay was associated with significantly higher AS use at 6 and 12 months compared with men who had MRI only, or no GPS or MRI testing. PMID- 29472825 TI - A Head-to-Head Comparative Phase II Study of Standard Urine Culture and Sensitivity Versus DNA Next-generation Sequencing Testing for Urinary Tract Infections. AB - Many studies have discussed clinical practice guidelines for the treatment of cystitis and pyelonephritis. Treatment of uncomplicated urinary tract infections (UTIs) can be based on empiric antibiotic therapy. For complicated or recurrent UTIs, therapy can be based on laboratory-controlled culture and sensitivity (C&S) reports. The diagnosis of UTI by clinical criteria alone has an error rate of up to 33%. In addition, positive laboratory culture results do not always indicate a diagnosis of UTI. Comparison of urine in a conventional culture model versus DNA next-generation sequencing (NGS) to accurately identify and provide information on resistance factors (mobile genetic elements) is warranted. Our study was a head-to-head comparative phase II study of standard urine C&S versus DNA NGS testing for the diagnosis and treatment efficacy in patients with symptoms of acute cystitis based on short-term outcomes.

PMID- 29472826 TI - The Use of Biomarkers in Prostate Cancer Screening and Treatment. AB - Prostate cancer screening and diagnosis has been guided by prostate-specific antigen levels for the past 25 years, but with the most recent US Preventive Services Task Force screening recommendations, as well as concerns regarding overdiagnosis and overtreatment, a new wave of prostate cancer biomarkers has recently emerged. These assays allow the testing of urine, serum, or prostate tissue for molecular signs of prostate cancer, and provide information regarding both diagnosis and prognosis. In this review, we discuss 12 commercially available biomarker assays approved for the diagnosis and treatment of prostate cancer. The results of clinical validation studies and clinical decision-making studies are presented. This information is designed to assist urologists in making clinical decisions with respect to ordering and interpreting these tests for different patients. There are numerous fluid and biopsy-based genomic tests available for prostate cancer patients that provide the physician and patient with different information about risk of future disease and treatment outcomes. It is important that providers be able to recommend the appropriate test for each individual patient; this decision is based on tissue availability and prognostic information desired. Future studies will continue to emphasize the important role of genomic biomarkers in making individualized treatment decisions for prostate cancer patients.

PMID- 29472833 TI - Cycling Trauma as a Cause of Arterial Priapism in Children and Teenagers. AB - Bicycle riding has multiple beneficial cardiovascular effects; however, it is a well-documented source of significant urologic injuries. Priapism is a rare condition in children, and occurs primarily because of congenital hematologic diseases or adverse drug reactions. A pediatric clinical case and literature review of a high-flow priapism secondary to cycling trauma is described here to highlight their etiopathologic correlation. Bicycle riding trauma is a rare but possible cause of high-flow priapism in children, and a high index of suspicion should ensure appropriate management. PMID- 29472834 TI - Real world data in health technology assessments in kidney transplants in Germany: use of routinely collected data to address epidemiologic questions in kidney transplants in the AMNOG process in Germany. AB - Introduction: It is discussed whether real world data can be used in health technology assessment. Following it is of interest whether routinely collected data for quality assurance (QA) in the hospital sector is feasible to address epidemiologic questions in kidney transplantation in the AMNOG process in Germany. Objectives: To investigate the proportion of kidney transplants classified as from so-called standard criteria donors (SCD) and from expanded criteria donors (ECD) in Germany and to study the age distribution. Methods: After granted use by the Federal Joint Committee (G-BA), the data analysis was carried out by the AQUA institute, and a SPSS code was developed. Special challenge was the complex definition of SCD/ECD criteria that, in addition to donor age, takes into account combinations of donor diagnoses, creatinine, and cold ischemia time. Results: Age analyses could be performed in all patients. Median age of the adult transplant recipients in Germany was 54 years in 2012 as well as in 2013, range 18-85 and 18-82 years and a mean (SD) of 53 (14) and 52 (14) years, respectively. 63.5% (2012) and 62.5% (2013) of recipients were male. Classification in SCD/ECD transplants could be performed for 2,083 of 2,461 patients (85%; 2012) and for 1,795 of 2,079 patients (86%; 2013). Of all classifiable transplants 61.4% (2012) and 66.5% (2013) were SCD transplants. Total project time from the request to results was <6 months. Conclusions: The use of data routinely collected for QA in the hospital sector is feasible to address epidemiologic questions in kidney transplantation in the AMNOG process in Germany, which is basically following the systematic of an HTA process. All patients with kidney transplants are represented thus avoiding sampling error. Limitations include the availability of all necessary data in the QA data set. Within <6 months' time with reasonable resources it was possible to meet timelines. The analyses were accepted by the authorities. PMID- 29472835 TI - Decreased Hippocampal Neuroplasticity and Behavioral Impairment in an Animal Model of Inhalant Abuse. AB - Thinners are highly toxic chemicals widely employed as organic solvents in industrial and domestic use. They have psychoactive properties when inhaled, and their chronic abuse as inhalants is associated with severe long-term health effects, including brain damage and cognitive-behavioral alterations. Yet, the sites and mechanisms of action of these compounds on the brain are far from being fully understood. Here, we investigated the consequences of paint thinner inhalation in adult male mice. Depression-like behaviors and an anxiolytic effect were found following repeated exposure in chronic treatments lasting 12 weeks. Both subchronic (6 weeks) and chronic treatments impaired learning and memory functions, while no changes were observed after acute treatment. To investigate possible molecular/structural alterations underlying such behavioral changes, we focused on the hippocampus. Notably, prolonged, but not acute thinner inhalation strongly affected adult neurogenesis in the dentate gyrus (DG), reducing progenitor cell proliferation after chronic treatments and impairing the survival of newborn neurons following both chronic and subchronic treatments. Furthermore, a down-regulation in the expression of BDNF and NMDA receptor subunits as well as a reduction in CREB expression/phosphorylation were found in the hippocampi of chronically treated mice. Our findings demonstrate for the first time significant structural and molecular changes in the adult hippocampus after prolonged paint thinner inhalation, indicating reduced hippocampal neuroplasticity and strongly supporting its implication in the behavioral dysfunctions associated to inhalant abuse. PMID- 29472836 TI - Group-Level EEG-Processing Pipeline for Flexible Single Trial-Based Analyses Including Linear Mixed Models. AB - Here we present an application of an EEG processing pipeline customizing EEGLAB and FieldTrip functions, specifically optimized to flexibly analyze EEG data based on single trial information. The key component of our approach is to create a comprehensive 3-D EEG data structure including all trials and all participants maintaining the original order of recording. This allows straightforward access to subsets of the data based on any information available in a behavioral data structure matched with the EEG data (experimental conditions, but also performance indicators, such accuracy or RTs of single trials). In the present study we exploit this structure to compute linear mixed models (LMMs, using lmer in R) including random intercepts and slopes for items. This information can easily be read out from the matched behavioral data, whereas it might not be accessible in traditional ERP approaches without substantial effort. We further provide easily adaptable scripts for performing cluster-based permutation tests (as implemented in FieldTrip), as a more robust alternative to traditional omnibus ANOVAs. Our approach is particularly advantageous for data with parametric within-subject covariates (e.g., performance) and/or multiple complex stimuli (such as words, faces or objects) that vary in features affecting cognitive processes and ERPs (such as word frequency, salience or familiarity), which are sometimes hard to control experimentally or might themselves constitute variables of interest. The present dataset was recorded from 40 participants who performed a visual search task on previously unfamiliar objects, presented either visually intact or blurred. MATLAB as well as R scripts are provided that can be adapted to different datasets. PMID- 29472837 TI - Spike-Timing Dependent Plasticity in Unipolar Silicon Oxide RRAM Devices. AB - Resistance switching, or Resistive RAM (RRAM) devices show considerable potential for application in hardware spiking neural networks (neuro-inspired computing) by mimicking some of the behavior of biological synapses, and hence enabling non-von Neumann computer architectures. Spike-timing dependent plasticity (STDP) is one such behavior, and one example of several classes of plasticity that are being examined with the aim of finding suitable algorithms for application in many computing tasks such as coincidence detection, classification and image recognition. In previous work we have demonstrated that the neuromorphic capabilities of silicon-rich silicon oxide (SiOx) resistance switching devices extend beyond plasticity to include thresholding, spiking, and integration. We previously demonstrated such behaviors in devices operated in the unipolar mode, opening up the question of whether we could add plasticity to the list of features exhibited by our devices. Here we demonstrate clear STDP in unipolar devices. Significantly, we show that the response of our devices is broadly similar to that of biological synapses. This work further reinforces the potential of simple two-terminal RRAM devices to mimic neuronal functionality in hardware spiking neural networks. PMID- 29472838 TI - Cancer Imprints an Increased PARP-1 and p53-Dependent Resistance to Oxidative Stress on Lymphocytes of Patients That Later Develop Alzheimer's Disease. AB - We have proposed that a common biological mechanism deregulated in opposite directions might explain the inverse epidemiological association observed between Alzheimer's disease (AD) and cancer. Accordingly, we showed that lymphocytes from AD patients have an increased susceptibility, whereas those from survivors of a skin cancer, an increased resistance to oxidative death induced by hydrogen peroxide (H2O2), compared to healthy controls (HC). We investigated the susceptibility to H2O2-induced death of lymphocytes in survivors of any type of cancer and in cancer survivors who later developed AD (Ca&AD). We also explored the involvement of Poly [ADP-ribose] polymerase-1 (PARP-1) and p53 pathways in the process, since both are involved in the increased susceptibility to death of AD lymphocytes. Lymphocytes from 11 cancer and 13 Ca&AD patients, and 12 HC were submitted to increasing concentrations of H2O2 for 20 h. Cell death was determined by flow cytometry, in the presence or absence of PARP-1 inhibition (3 aminobenzamide, 3-ABA), or p53 inhibition (pifithrin-alpha) or stabilization (Nut 3). PARP-1 and p53 mRNA levels were determined by Real-Time PCR. Lymphocytes from cancer and Ca&AD patients showed increased survival compared to HC, without differences between them, opposite to the increased susceptibility to death previously shown in AD. PARP-1 inhibition provided marked protection from H2O2 induced death in the two groups of patients, significantly greater than in HC. Pharmacological inhibition of p53 increased lymphocyte survival in Ca&AD patients, contrary to the effect previously reported in HC and AD. PARP-1 and p53 mRNA levels were elevated in Ca&AD lymphocytes compared with controls. In all, these results show that cancer imprints an increased resistance to H2O2-induced death in lymphocytes that persists after AD development, and is dependent on both PARP-1 and p53. p53 inhibition showed a differential role in cancer and Ca&AD compared to HC and AD lymphocytes, that could explain the inverse susceptibility to oxidative death in cancer and AD. These results are in agreement with the hypothesis of a common biological mechanism in AD and cancer. The similar cell death susceptibility and cell death pattern observed in cancer and Ca&AD lymphocytes suggests that cancer history leaves long term effects on lymphocyte cell death susceptibility. PMID- 29472839 TI - Ketamine Modulates Zic5 Expression via the Notch Signaling Pathway in Neural Crest Induction. AB - Ketamine is a potent dissociative anesthetic and the most commonly used illicit drug. Many addicts are women at childbearing age. Although ketamine has been extensively studied as a clinical anesthetic, its effects on embryonic development are poorly understood. Here, we applied the Xenopus model to study the effects of ketamine on development. We found that exposure to ketamine from pre-gastrulation (stage 7) to early neural plate (stage 13.5) resulted in disruption of neural crest (NC) derivatives. Ketamine exposure did not affect mesoderm development as indicated by the normal expression of Chordin, Xbra, Wnt8, and Fgf8. However, ketamine treatment significantly inhibited Zic5 and Slug expression at early neural plate stage. Overexpression of Zic5 rescued ketamine induced Slug inhibition, suggesting the blockage of NC induction was mediated by Zic5. Furthermore, we found Notch signaling was altered by ketamine. Ketamine inhibited the expression of Notch targeted genes including Hes5.2a, Hes5.2b, and ESR1 and ketamine-treated embryos exhibited Notch-deficient somite phenotypes. A 15 bp core binding element upstream of Zic5 was induced by Notch signaling and caused transcriptional activation. These results demonstrated that Zic5 works as a downstream target gene of Notch signaling in Xenopus NC induction. Our study provides a novel teratogenic mechanism whereby ketamine disrupts NC induction via targeting a Notch-Zic5 signaling pathway. PMID- 29472840 TI - Prenatal Immune Challenge in Mice Leads to Partly Sex-Dependent Behavioral, Microglial, and Molecular Abnormalities Associated with Schizophrenia. AB - Epidemiological studies revealed that environmental factors comprising prenatal infection are strongly linked to risk for later development of neuropsychiatric disorders such as schizophrenia. Considering strong sex differences in schizophrenia and its increased prevalence in males, we designed a methodological approach to investigate possible sex differences in pathophysiological mechanisms. Prenatal immune challenge was modeled by systemic administration of the viral mimic polyinosinic-polycytidylic acid (Poly I:C) to C57BL/6 mice at embryonic day 9.5. The consequences on behavior, gene expression, and microglia brain immune cells that are critical for normal development-were characterized in male vs. female offspring at adulthood. The cerebral cortex, hippocampus, and cerebellum, regions where structural and functional alterations were mainly described in schizophrenia patients, were selected for cellular and molecular analyses. Confocal and electron microscopy revealed most pronounced differences in microglial distribution, arborization, cellular stress, and synaptic interactions in the hippocampus of male vs. female offspring exposed to Poly I:C. Sex differences in microglia were also measured under both steady-state and Poly I:C conditions. These microglial alterations were accompanied by behavioral impairment, affecting for instance sensorimotor gating, in males. Consistent with these results, increased expression of genes related to inflammation was measured in cerebral cortex and hippocampus of males challenged with Poly I:C. Overall, these findings suggest that schizophrenia's higher incidence in males might be associated, among other mechanisms, with an increased microglial reactivity to prenatal immune challenges, hence determining disease outcomes into adulthood. PMID- 29472841 TI - The Absence of Sensory Axon Bifurcation Affects Nociception and Termination Fields of Afferents in the Spinal Cord. AB - A cGMP signaling cascade composed of C-type natriuretic peptide, the guanylyl cyclase receptor Npr2 and cGMP-dependent protein kinase I (cGKI) controls the bifurcation of sensory axons upon entering the spinal cord during embryonic development. However, the impact of axon bifurcation on sensory processing in adulthood remains poorly understood. To investigate the functional consequences of impaired axon bifurcation during adult stages we generated conditional mouse mutants of Npr2 and cGKI (Npr2fl/fl;Wnt1Cre and cGKIKO/fl;Wnt1Cre ) that lack sensory axon bifurcation in the absence of additional phenotypes observed in the global knockout mice. Cholera toxin labeling in digits of the hind paw demonstrated an altered shape of sensory neuron termination fields in the spinal cord of conditional Npr2 mouse mutants. Behavioral testing of both sexes indicated that noxious heat sensation and nociception induced by chemical irritants are impaired in the mutants, whereas responses to cold sensation, mechanical stimulation, and motor coordination are not affected. Recordings from C-fiber nociceptors in the hind limb skin showed that Npr2 function was not required to maintain normal heat sensitivity of peripheral nociceptors. Thus, the altered behavioral responses to noxious heat found in Npr2fl/fl;Wnt1Cre mice is not due to an impaired C-fiber function. Overall, these data point to a critical role of axonal bifurcation for the processing of pain induced by heat or chemical stimuli. PMID- 29472842 TI - Accumulation of Cav3.2 T-type Calcium Channels in the Uninjured Sural Nerve Contributes to Neuropathic Pain in Rats with Spared Nerve Injury. AB - Injuries to peripheral nerve fibers induce neuropathic pain. But the involvement of adjacent uninjured fibers to pain is not fully understood. The present study aims to investigate the possible contribution of Cav3.2 T-type calcium channels in uninjured afferent nerve fibers to neuropathic pain in rats with spared nerve injury (SNI). Abeta-, Adelta- and C-fibers of the uninjured sural nerve were sensitized revealed by in vivo single-unit recording, which were accompanied by accumulation of Cav3.2 T-type calcium channel proteins shown by Western blotting. Application of mibefradil, a T-type calcium channel blocker, to sural nerve receptive fields increased mechanical thresholds of Abeta-, Adelta- and C-fibers, confirming the functional involvement of accumulated channels in the sural nerve in SNI rats. Finally, perineural application of mibefradil or TTA-P2 to the uninjured sural nerve alleviated mechanical allodynia in SNI rats. These results suggest that axonal accumulation of Cav3.2 T-type calcium channels plays an important role in the uninjured sural nerve sensitization and contributes to neuropathic pain. PMID- 29472843 TI - A Fat-Facets-Dscam1-JNK Pathway Enhances Axonal Growth in Development and after Injury. AB - Injury to the adult central nervous systems (CNS) can result in severe long-term disability because damaged CNS connections fail to regenerate after trauma. Identification of regulators that enhance the intrinsic growth capacity of severed axons is a first step to restore function. Here, we conducted a gain-of function genetic screen in Drosophila to identify strong inducers of axonal growth after injury. We focus on a novel axis the Down Syndrome Cell Adhesion Molecule (Dscam1), the de-ubiquitinating enzyme Fat Facets (Faf)/Usp9x and the Jun N-Terminal Kinase (JNK) pathway transcription factor Kayak (Kay)/Fos. Genetic and biochemical analyses link these genes in a common signaling pathway whereby Faf stabilizes Dscam1 protein levels, by acting on the 3'-UTR of its mRNA, and Dscam1 acts upstream of the growth-promoting JNK signal. The mammalian homolog of Faf, Usp9x/FAM, shares both the regenerative and Dscam1 stabilizing activities, suggesting a conserved mechanism. PMID- 29472845 TI - Editorial: Metastable Dynamics of Neural Ensembles. PMID- 29472844 TI - F-spondin Is Essential for Maintaining Circadian Rhythms. AB - The suprachiasmatic nucleus (SCN) is the master pacemaker that drives circadian behaviors. SCN neurons have intrinsic, self-sustained rhythmicity that is governed by transcription-translation feedback loops. Intrinsic rhythms within the SCN do not match the day-night cycle and are therefore entrained by light derived cues. Such cues are transmitted to the SCN by a class of intrinsically photosensitive retinal ganglion cells (ipRGCs). In the present study, we sought to identify how axons from ipRGCs target the SCN. While none of the potential targeting cues identified appeared necessary for retinohypothalamic innervation, we unexpectedly identified a novel role for the extracellular matrix protein F spondin in circadian behavior. In the absence of F-spondin, mice lost their ability to maintain typical intrinsic rhythmicity. Moreover, F-spondin loss results in the displacement of vasoactive intestinal peptide (VIP)-expressing neurons, a class of neurons that are essential for maintaining rhythmicity among SCN neurons. Thus, this study highlights a novel role for F-spondin in maintaining circadian rhythms. PMID- 29472846 TI - Risk Preferences and Predictions about Others: No Association with 2D:4D Ratio. AB - Prenatal androgen exposure affects the brain development of the fetus which may facilitate certain behaviors and decision patterns in the later life. The ratio between the lengths of second and the fourth fingers (2D:4D) is a negative biomarker of the ratio between prenatal androgen and estrogen exposure and men typically have lower ratios than women. In line with the typical findings suggesting that women are more risk averse than men, several studies have also shown negative relationships between 2D:4D and risk taking although the evidence is not conclusive. Previous studies have also reported that both men and women believe women are more risk averse than men. In the current study, we re-test the relationship between 2D:4D and risk preferences in a German student sample and also investigate whether the 2D:4D ratio is associated with people's perceptions about others' risk preferences. Following an incentivized risk elicitation task, we asked all participants their predictions about (i) others' responses (without sex specification), (ii) men's responses, and (iii) women's responses; then measured their 2D:4D ratios. In line with the previous findings, female participants in our sample were more risk averse. While both men and women underestimated other participants' (non sex-specific) and women's risky decisions on average, their predictions about men were accurate. We also found evidence for the false consensus effect, as risky choices are positively correlated with predictions about other participants' risky choices. The 2D:4D ratio was not directly associated either with risk preferences or the predictions of other participants' choices. An unexpected finding was that women with mid-range levels of 2D:4D estimated significantly larger sex differences in participants' decisions. This finding needs further testing in future studies. PMID- 29472847 TI - Balance Training Reduces Brain Activity during Motor Simulation of a Challenging Balance Task in Older Adults: An fMRI Study. AB - Aging is associated with a shift from an automatic to a more cortical postural control strategy, which goes along with deteriorations in postural stability. Although balance training has been shown to effectively counteract these behavioral deteriorations, little is known about the effect of balance training on brain activity during postural tasks in older adults. We, therefore, assessed postural stability and brain activity using fMRI during motor imagery alone (MI) and in combination with action observation (AO; i.e., AO+MI) of a challenging balance task in older adults before and after 5 weeks of balance training. Results showed a nonsignificant trend toward improvements in postural stability after balance training, accompanied by reductions in brain activity during AO+MI of the balance task in areas relevant for postural control, which have been shown to be over-activated in older adults during (simulation of) motor performance, including motor, premotor, and multisensory vestibular areas. This suggests that balance training may reverse the age-related cortical over-activations and lead to changes in the control of upright posture toward the one observed in young adults. PMID- 29472848 TI - Spike Train Similarity Space (SSIMS) Method Detects Effects of Obstacle Proximity and Experience on Temporal Patterning of Bat Biosonar. AB - Bats emit biosonar pulses in complex temporal patterns that change to accommodate dynamic surroundings. Efforts to quantify these patterns have included analyses of inter-pulse intervals, sonar sound groups, and changes in individual signal parameters such as duration or frequency. Here, the similarity in temporal structure between trains of biosonar pulses is assessed. The spike train similarity space (SSIMS) algorithm, originally designed for neural activity pattern analysis, was applied to determine which features of the environment influence temporal patterning of pulses emitted by flying big brown bats, Eptesicus fuscus. In these laboratory experiments, bats flew down a flight corridor through an obstacle array. The corridor varied in width (100, 70, or 40 cm) and shape (straight or curved). Using a relational point-process framework, SSIMS was able to discriminate between echolocation call sequences recorded from flights in each of the corridor widths. SSIMS was also able to tell the difference between pulse trains recorded during flights where corridor shape through the obstacle array matched the previous trials (fixed, or expected) as opposed to those recorded from flights with randomized corridor shape (variable, or unexpected), but only for the flight path shape in which the bats had previous training. The results show that experience influences the temporal patterns with which bats emit their echolocation calls. It is demonstrated that obstacle proximity to the bat affects call patterns more dramatically than flight path shape. PMID- 29472849 TI - EEG-Based Brain-Computer Interfaces for Communication and Rehabilitation of People with Motor Impairment: A Novel Approach of the 21 st Century. AB - People with severe neurological impairments face many challenges in sensorimotor functions and communication with the environment; therefore they have increased demand for advanced, adaptive and personalized rehabilitation. During the last several decades, numerous studies have developed brain-computer interfaces (BCIs) with the goals ranging from providing means of communication to functional rehabilitation. Here we review the research on non-invasive, electroencephalography (EEG)-based BCI systems for communication and rehabilitation. We focus on the approaches intended to help severely paralyzed and locked-in patients regain communication using three different BCI modalities: slow cortical potentials, sensorimotor rhythms and P300 potentials, as operational mechanisms. We also review BCI systems for restoration of motor function in patients with spinal cord injury and chronic stroke. We discuss the advantages and limitations of these approaches and the challenges that need to be addressed in the future. PMID- 29472850 TI - Slow Is Also Fast: Feedback Delay Affects Anxiety and Outcome Evaluation. AB - Performance-related feedback plays an important role in improving human being's adaptive behavior. Using event-related potentials (ERPs), previous studies have associated a particular component, i.e., reward positivity (RewP), with outcome evaluation processing and found that this component was affected by waiting time before outcome evaluation. Prior research has also suggested that anxious individuals are more prone to detecting threats and susceptible to negative emotions, and show different patterns of brain activity in outcome evaluation. It is quite common that a decision-maker cannot receive feedback immediately; however, few studies have focused on the processing of delayed feedback, especially in subjects who exhibit trait anxiety. In this study, we recruited two groups of subjects with different trait anxiety levels and recorded ERPs when they conducted a time-estimation task with short (0.6-1 s) or long delayed (4-5 s) feedback. The ERP results during the cue phase showed that long waiting cues elicited more negative-going feedback-related negativity (FRN)-like component than short waiting cues in the high trait anxiety (HTA) group. More importantly, the two groups showed different patterns of ERP in the feedback condition. In the low trait anxiety (LTA) group, more positive-going RewP was found in the short delayed than in the long-delayed condition. In contrast, no difference was found in the HTA group. This pattern may reflect the hyperactivity of the reward systems of HTA individuals in uncertain environments (e.g., the long-delay condition) compared with LTA individuals. Our results provide a direction for future research on the neural mechanisms of reinforcement learning and anxiety. PMID- 29472851 TI - Self-Active Relaxation Therapy (SART) and Self-Regulation: A Comprehensive Review and Comparison of the Japanese Body Movement Approach. AB - Relaxation programs are known for their versatility, cost-effectiveness, and ability to help people obtain skills to regulate their mental states and promote and maintain health. Self-Active Relaxation Therapy (SART) is a body-oriented approach to psychological rehabilitation that grew out of the suite of movement tasks developed in the Japanese psychotherapy known as Dohsa-hou, or the body movement method. The program for SART is designed to stretch, twist, and release areas of the upper, lower, and whole body through a set of movements which are guided by the practitioner and performed "self-actively" by the client to empower them to learn to recognize points of tension in the body and act on their own to achieve a relaxed state. Numerous studies have showed that SART is associated with reduced negative mood states and enhanced body awareness. A short version of SART has been investigated as a psychological support salon activity for the elderly, mothers raising children, special needs students, and children adapting to school. The full program has also been applied in clinical settings to address or supplement treatments for psychological and developmental conditions, and longitudinally employed in community contexts to assist residents facing long term disaster recovery circumstances in Japan. This paper reviews the research and applications of SART as a bodymind approach by critically examining evidence and research gaps for future studies, comparing it with techniques established in the literature, and positing a self-regulatory framework for SART as a tool to become aware of bodily states, regulate mood, and manage stress through the deliberate practice of relaxation. PMID- 29472852 TI - It Is Not Just in Faces! Processing of Emotion and Intention from Biological Motion in Psychiatric Disorders. AB - Social neuroscience offers a wide range of techniques that may be applied to study the social cognitive deficits that may underlie reduced social functioning a common feature across many psychiatric disorders. At the same time, a significant proportion of research in this area has been conducted using paradigms that utilize static displays of faces or eyes. The use of point-light displays (PLDs) offers a viable alternative for studying recognition of emotion or intention inference while minimizing the amount of information presented to participants. This mini-review aims to summarize studies that have used PLD to study emotion and intention processing in schizophrenia (SCZ), affective disorders, anxiety and personality disorders, eating disorders and neurodegenerative disorders. Two main conclusions can be drawn from the reviewed studies: first, the social cognitive problems found in most of the psychiatric samples using PLD were of smaller magnitude than those found in studies presenting social information using faces or voices. Second, even though the information presented in PLDs is extremely limited, presentation of these types of stimuli is sufficient to elicit the disorder-specific, social cognitive biases (e.g., mood-congruent bias in depression, increased threat perception in anxious individuals, aberrant body size perception in eating disorders) documented using other methodologies. Taken together, these findings suggest that point-light stimuli may be a useful method of studying social information processing in psychiatry. At the same time, some limitations of using this methodology are also outlined. PMID- 29472853 TI - Relevance of Phosphorylation and Truncation of Tau to the Etiopathogenesis of Alzheimer's Disease. AB - Microtubule (MT) associated protein tau is abnormally hyperphosphorylated and aggregated into paired helical filaments (PHFs), which manifest as neurofibrillary tangles (NFTs) in the brains of individuals with Alzheimer's disease (AD) and related tauopathies. Hyperphosphorylation and truncation of tau have been linked to the progression of the disease. However, the nature of phosphorylation and truncation of tau in AD brain are not very clear. In the present study we investigated the association of phosphorylation and truncation with high-molecular weight oligomers of tau (HMW-tau) in post-mortem AD brain by western blots. We found that tau from AD brain appears as a smear from low molecular weight (LMW) to HMW tau species in western blots developed with pan-tau antibodies. Similar level of LMW-tau was found in AD and control brains, whereas HMW-tau was found in AD brain only. HMW-tau was hyperphosphorylated at multiple sites and not unphosphorylated at Ser46 or Ser198/199/202. HMW-tau was weakly labeled by tau antibodies 43D against a.a. 6-18 and HT7 against a.a. 159-163 of tau, whereas, the C-terminal antibodies, tau46 and tau46.1, strongly labeled HMW tau. The ratio of HMW-tau/LMW-tau detected by tau antibodies increased as the epitope of the tau antibodies ranges from N-terminal to C-terminal. The level of tau truncated at Asp421 was increased in AD brain, but was poorly associated with the HMW-tau. These findings suggest that tau pathogenesis involves both hyperphosphorylation and dominantly N-terminal truncation of tau in AD. PMID- 29472854 TI - Altered Connectivity of the Anterior Cingulate and the Posterior Superior Temporal Gyrus in a Longitudinal Study of Later-life Depression. AB - Patients with later-life depression (LLD) show abnormal gray matter (GM) volume, white matter (WM) integrity and functional connectivity in the anterior cingulate cortex (ACC) and posterior superior temporal gyrus (pSTG), but it remains unclear whether these abnormalities persist over time. We examined whether structural and functional abnormalities in these two regions are present within the same subjects during depressed vs. remitted phases. Sixteen patients with LLD and 30 healthy subjects were studied over a period of 1.5 years. Brain images obtained with a 3-Tesla magnetic resonance imaging (MRI) system were analyzed by voxel based morphometry of the GM volume, and diffusion tensor imaging (DTI) and resting-state functional MRI were used to assess ACC-pSTG connectivity. Patients with LLD in the depressed and remitted phases showed significantly smaller GM volume in the left ACC and left pSTG than healthy subjects. Both patients with LLD in the depressed and remitted phases had significantly higher diffusivities in the WM tract of the left ACC-pSTG than healthy subjects. Remitted patients with LLD showed lower functional ACC-pSTG connectivity compared to healthy subjects. No difference was found in the two regions between depressed and remitted patients in GM volume, structural or functional connectivity. Functional ACC-pSTG connectivity was positively correlated with lower global function during remission. Our preliminary data show that structural and functional abnormalities of the ACC and pSTG occur during LLD remission. Our findings tentatively reveal the brain pathophysiology involved in LLD and may aid in developing neuroanatomical biomarkers for this condition. PMID- 29472856 TI - Silibinin Inhibits NSCLC Metastasis by Targeting the EGFR/LOX Pathway. AB - Tumor metastasis is the most lethal and debilitating process that threatens cancer patients. Among the regulators involved in tumor metastasis, lysyl oxidase (LOX) is an important contributor for tumor invasion, migration and the formation of the pre-metastatic niche. Although the relationship between LOX and poor prognosis of lung patients has been preliminary reported, the mechanism remains poorly understood. Here, we found that LOX overexpression is closely related to the survival of lung adenocarcinoma patients but not squamous cell carcinoma patients. Moreover, we confirmed that LOX expression is regulated by the activation of epidermal growth factor receptor (EGFR) via the PI3K/AKT, MEK/ERK, and SAPK/JNK signaling pathways in non-small cell lung cancer (NSCLC). Meanwhile, the study also suggested that the traditional anti-fibrosis drug silibinin inhibited NSCLC cell migration in an EGFR/LOX dependent manner. In addition, an orthotopic implantation metastasis model also confirmed that the EGFR inhibitor WZ4002 and silibinin decreased tumor metastasis through the EGFR/LOX pathway. Altogether, this study revealed that LOX expression is regulated by the EGFR pathway and this may account for the anti-cancer metastasis effects of silibinin, indicating LOX as a potentially therapeutic target for NSCLC treatment.

AB - The nucleus accumbens shell is a site of converging inputs during memory processing for emotional events. The accumbens receives input from the nucleus of the solitary tract (NTS) regarding changes in peripheral autonomic functioning following emotional arousal. The shell also receives input from the amygdala and hippocampus regarding affective and contextual attributes of new learning experiences. The successful encoding of affect or context is facilitated by activating noradrenergic systems in either the amygdala or hippocampus. Recent findings indicate that memory enhancement produced by activating NTS neurons, is attenuated by suppressing accumbens functioning after learning. This finding illustrates the significance of the shell in integrating information from the periphery to modulate memory for arousing events. However, it is not known if the accumbens shell plays an equally important role in consolidating information that is initially processed in the amygdala and hippocampus. The present study determined if the convergence of inputs from these limbic regions within the nucleus accumbens contributes to successful encoding of emotional events into memory. Male Sprague-Dawley rats received bilateral cannula implants 2 mm above the accumbens shell and a second bilateral implant 2 mm above either the amygdala or hippocampus. The subjects were trained for 6 days to drink from a water spout. On day 7, a 0.35 mA footshock was initiated as the rat approached the spout and was terminated once the rat escaped into a white compartment. Subjects were then given intra-amygdala or hippocampal infusions of PBS or a dose of norepinephrine (0.2 MUg) previously shown to enhance memory. Later, all subjects were given intra-accumbens infusion of muscimol to functionally inactivate the shell. Muscimol inactivation of the accumbens shell was delayed to allow sufficient time for norepinephrine to activate intracellular cascades that lead to long-term synaptic modifications involved in forming new memories. Results show that memory improvement produced by infusing norepinephrine in either the amygdala or hippocampus is attenuated by interrupting neuronal activity in the shell 1 or 7 7 h following amygdala or hippocampus activation. These findings suggest that the accumbens shell plays an integral role modulating information initially processed by the amygdala and hippocampus following exposure to emotionally arousing events. Additionally, results demonstrate that the accumbens is involved in the long-term consolidation processes lasting over 7 h. PMID- 29472858 TI - An Integrated Lipidomics and Phenotype Study Reveals Protective Effect and Biochemical Mechanism of Traditionally Used Alisma orientale Juzepzuk in Chronic Kidney Disease. AB - Alisma orientale Juzepzuk (AO) is widely used for various diuretic and nephropathic treatments in traditional Chinese medicines (TCM). In a clinical setting, AO is used as both a lipid-lowering and tubular interstitial fibrosis agent. However, the mechanisms of AO for the treatment of renal interstitial fibrosis and abnormal lipid metabolism are not well-understood. In this study, pharmacological and UPLC-HDMS-based lipidomic approaches were employed to investigate the lipid-lowering and tubular interstitial fibrosis effect of AO on rats with adenine-induced chronic kidney disease (CKD). Rats with CKD showed increased serum levels of creatinine and urea, tubular damage, and tubular interstitial fibrosis. Moreover, multiple lipid species were identified in CKD rats. Among these lipids, polyunsaturated fatty acid, eicosapentaenoic acid, 8,9 epoxyeicosatrienoic acid, and docosahexaenoic acid levels were significantly decreased in CKD rats compared to control rats. In CKD rats, up-regulation of the NF-kappaB pathway may impair polyunsaturated fatty acid metabolism, causing renal fibrosis. In addition, CKD rats showed significantly decreased diglyceride levels and increased triglyceride levels compared to the control group. Pathway over representation analysis demonstrated that 30 metabolic pathways were associated with lipid species. AO treatment suppressed up-regulation of inflammation, and partly restored the deregulation of polyunsaturated fatty acids and glycerolipids metabolism. Our results indicated that AO treatment attenuated renal fibrosis by down-regulating inflammation, and mitigating lipid metabolism in CKD rats. In conclusion, this study has identified the therapeutic lipid-lowering and anti fibrosis effects of AO on CKD. PMID- 29472855 TI - Role of Copper in the Onset of Alzheimer's Disease Compared to Other Metals. AB - Alzheimer's disease (AD) is a neurodegenerative disorder that is characterized by amyloid plaques in patients' brain tissue. The plaques are mainly made of beta amyloid peptides and trace elements including Zn2+, Cu2+, and Fe2+. Some studies have shown that AD can be considered a type of metal dyshomeostasis. Among metal ions involved in plaques, numerous studies have focused on copper ions, which seem to be one of the main cationic elements in plaque formation. The involvement of copper in AD is controversial, as some studies show a copper deficiency in AD, and consequently a need to enhance copper levels, while other data point to copper overload and therefore a need to reduce copper levels. In this paper, the role of copper ions in AD and some contradictory reports are reviewed and discussed. PMID- 29472859 TI - Zinc Oxide Nanoparticle Caused Plasma Metabolomic Perturbations Correlate with Hepatic Steatosis. AB - Zinc oxide nanoparticles (ZnO NPs), known for their chemical stability and strong adsorption, are used in everyday items such as cosmetics, sunscreens, and prophylactic drugs. However, they have also been found to adversely affect organisms; previously we found that ZnO NPs disrupt pubertal ovarian development, inhibit embryonic development by upsetting gamma-H2AX and NF-kappaB pathways, and even disturb skin stem cells. Non-targeted metabolomic analysis of biological organisms has been suggested as an unbiased tool for the investigation of perturbations in response to NPs and their underlying mechanisms. Although metabolomics has been used in nanotoxicological studies, very few reports have used it to investigate the effects of ZnO NPs exposure. In the current investigation, through a metabolomics-based approach, we discovered that ZnO NPs caused changes in plasma metabolites involved in anti-oxidative mechanisms, energy metabolism, and lipid metabolism in hen livers. These results are in line with earlier findings that ZnO NPs perturb the tricarboxylic acid cycle and in turn result in the use of alternative energy sources. We also found that ZnO NPs disturbed lipid metabolism in the liver and consequently impacted blood lipid balance. Changes in plasma metabolomes were correlated with hepatic steatosis. PMID- 29472860 TI - Magnesium Lithospermate B Protects against Lipopolysaccharide-Induced Bone Loss by Inhibiting RANKL/RANK Pathway. AB - Lipopolysaccharide (LPS) can induce bone loss by stimulating bone resorption. Natural compounds have great potential for the treatment of osteolytic bone diseases. Magnesium lithospermate B (MLB) plays an important role in protecting against oxidative damage and also has potential anti-inflammatory pharmacological properties. However, its role in LPS-induced bone loss is still unknown. In the present study, we observed the effects of MLB on LPS-induced bone damage and investigated the possible mechanisms. The bone loss models were established by LPS administration in male Sprague-Dawley rats. MLB (200 mg/kg body weight) was given by subcutaneous injection. MicroCT analysis, biomarker assay, histological examination and immunohistochemical staining were performed at the 8th weeks. In addition, RAW264.7 cells were treated with LPS in the presence or absence of MLB. The osteoclast formation, resorption activity and differentiation-related genes [(receptor activator of nuclear factor kappa-B (RANK), Traf6, Fra-1, and c-src)] expression were evaluated. LPS induced bone loss shown as the decrease in bone volume fraction and trabecular number, and increase in trabecular separation. LPS also markedly enhanced the osteoclast formation and resorption activity compared with the control. MLB significantly abolished the LPS-induced bone microstructure damage (p < 0.05) and osteoclast formation. MLB also inhibited the increases of serum tartrate-resistant acid phosphatase 5b, RANK ligand (RANKL) and TNF-alpha level enhanced by LPS (p < 0.05). Immunohistochemical staining indicated that MLB attenuated the high expression of RANKL and RANK stimulated by LPS. In addition, MLB significantly abolished the LPS-enhanced osteoclast formation, resorption activity, RANK, Traf6, Fra-1, and c-src expression in vitro. Our data demonstrate that MLB can suppress LPS-induced bone loss via inhibiting RANKL/RANK related osteoclast formation. PMID- 29472861 TI - 1,2,3,4,6-Penta-O-Galloyl-Beta-D-Glucopyranoside Inhibits Proliferation of Multiple Myeloma Cells Accompanied with Suppression of MYC Expression. AB - Multiple myeloma (MM) still remains an incurable disease, therefore discovery of novel drugs boosts the therapeutics for MM. The natural compound 1,2,3,4,6-Penta O-galloyl-beta-D-glucopyranoside (PGG) has been shown to exhibit antitumor activities against various cancer cells. Here, we aim to evaluate antitumor effects of PGG on MM cell lines. PGG inhibited the growth of three different MM cell lines in a dose- and time-dependent manner. Cell cycle analysis revealed that PGG treatment caused cell cycle arrest in G1 phase. It also induced apoptosis which was indicated by significant increases of Annexin V positive cells, caspase 3/7 activity, and cleaved caspase 3 expression in PGG treated MM cell. Since MYC is frequently hyperactivated in MM and inhibition of MYC leads to MM cell death. We further demonstrated that PGG decreased MYC expression in protein and mRNA levels and reversed the mRNA expression of MYC target genes such as p21, p27, and cyclin D2. In addition, PGG also reduced protein expression of DEPTOR which is commonly overexpressed in MM. Unexpectedly, PGG antagonized the cytotoxic effect of bortezomib in the combination treatment. However, PGG treatment sensitized MM cells to another proteasome inhibitor MG132 induced cytotoxicity. Moreover, MYC inhibitor JQ1 enhanced the cytotoxic effect of bortezomib on MM cells. Our findings raised concerns about the combinatory use of bortezomib with particular types of chemicals. The evidence also provide useful insights into the combination of MYC and proteasome-inhibitors for MM therapy. Finally, PGG has a therapeutic potential for treatment of MM and further development is mandatory.

PMID- 29472863 TI - beta2-Adrenergic Receptor Activation Suppresses the Rat Phenethylamine Hallucinogen-Induced Head Twitch Response: Hallucinogen-Induced Excitatory Post synaptic Potentials as a Potential Substrate. AB - 5-Hydroxytryptamine2A (5-HT2A) receptors are enriched in layers I and Va of the rat prefrontal cortex and neocortex and their activation increases the frequency of glutamatergic excitatory post-synaptic potentials/currents (EPSP/Cs) onto layer V pyramidal cells. A number of other G-protein coupled receptors (GPCRs) are also enriched in cortical layers I and Va and either induce (alpha1 adrenergic and orexin2) or suppress (metabotropic glutamate2 [mGlu2], adenosine A1, MU-opioid) both 5-HT-induced EPSCs and head twitches or head shakes induced by the phenethylamine hallucinogen 2,5-dimethoxy-4-iodoamphetamine (DOI). Another neurotransmitter receptor also localized to apparent thalamocortical afferents to layers I and Va of the rat prefrontal cortex and neocortex is the beta2 adrenergic receptor. Therefore, we conducted preliminary electrophysiological experiments with rat brain slices examining the effects of epinephrine on electrically-evoked EPSPs following bath application of DOI (3 MUM). Epinephrine (0.3-10 MUM) suppressed the late EPSPs produced by electrical stimulation and DOI. The selective beta2-adrenergic receptor antagonist ICI-118,551 (300 nM) resulted in a rightward shift of the epinephrine concentration-response relationship. We also tested the selective beta2-adrenergic receptor agonist clenbuterol and the antagonist ICI-118,551 on DOI-induced head twitches. Clenbuterol (0.3-3 mg/kg, i.p.) suppressed DOI (1.25 mg/kg, i.p.)-induced head twitches. This clenbuterol effect appeared to be at least partially reversed by the selective beta2-adrenergic receptor antagonist ICI-118,553 (0.01-1 mg/kg, i.p.), with significant reversal at doses of 0.1 and 1 mg/kg. Thus, beta2 adrenergic receptor activation reverses the effects of phenethylamine hallucinogens in the rat prefrontal cortex. While Gi/Go-coupled GPCRs have previously been shown to suppress both the electrophysiological and behavioral effects of 5-HT2A receptor activation in the mPFC, the present work appears to extend this suppressant action to a Gs-coupled GPCR. Furthermore, the modulation of 5-HT2A receptor activation-induced glutamate release onto mPFC layer V pyramidal neurons apical dendrites by a range GPCRs in rat brain slices appears to results in behaviorally salient effects of relevance when screening for novel CNS therapeutic drugs. PMID- 29472864 TI - Paeonol Inhibits Oxidized Low-Density Lipoprotein-Induced Vascular Endothelial Cells Autophagy by Upregulating the Expression of miRNA-30a. AB - Paeonol from Cortex Moutan root is a potential therapeutic agent for atherosclerosis (AS). However, its mechanisms of action are still not fully understood. Vascular endothelial cells (VECs) autophagy plays a vital role in the initiation and progression of AS. In this study, we aim to investigate whether the protective effect of paeonol on ox-LDL-induced VECs injury by regulating autophagy. To address this question, we used ox-LDL-induced rat VECs as a model system to elucidate the protective effect of paeonol on VECs injury. This study displayed that ox-LDL (100 mg/L) treatment inhibited VEC growth in dose- and time dependent manners, paeonol (60 MUM) shown potential in inhibiting ox-LDL-induced death. Furthermore, paeonol significantly reduced ox-LDL-induced the formation of autophagy vacuoles and the expression of LC3II in VECs. Further double-luciferase reporter assay shown that miR-30a specifically binds to the 3'-UTR of Beclin-1 mRNA in VECs. Moreover, we found that ox-LDL decreased miR-30a and increased Beclin-1 expression, pretreatment with paeonol could reverse the process of regulation in dose-dependent manners. In ox-LDL treated VECs, transfection with a miR-30a mimic significantly increased miR-30a expression and inhibited Beclin-1 and LC3II expression, thus enhanced the protective effects of paeonol. Whereas transfection with a miR-30a inhibitor significantly decreased miR-30a expression and increased Beclin-1 and LC3II expression, thus attenuated the protective effects of paeonol. In conclusion, this study has, for the ?rst time, highlighted that miR-30a might be a critical target of paeonol against ox-LDL-induced VECs injury by inhibiting excessive autophagy. Paeonol may be one of promising candidate drug for treatment of AS. PMID- 29472865 TI - Intracranial Pressure Is a Determinant of Sympathetic Activity. AB - Intracranial pressure (ICP) is the pressure within the cranium. ICP rise compresses brain vessels and reduces cerebral blood delivery. Massive ICP rise leads to cerebral ischemia, but it is also known to produce hypertension, bradycardia and respiratory irregularities due to a sympatho-adrenal mechanism termed Cushing response. One still unresolved question is whether the Cushing response is a non-synaptic acute brainstem ischemic mechanism or part of a larger physiological reflex for arterial blood pressure control and homeostasis regulation. We hypothesize that changes in ICP modulates sympathetic activity. Thus, modest ICP increase and decrease were achieved in mice and patients with respectively intra-ventricular and lumbar fluid infusion. Sympathetic activity was gauged directly by microneurography, recording renal sympathetic nerve activity in mice and muscle sympathetic nerve activity in patients, and gauged indirectly in both species by heart-rate variability analysis. In mice (n = 15), renal sympathetic activity increased from 29.9 +/- 4.0 bursts.s-1 (baseline ICP 6.6 +/- 0.7 mmHg) to 45.7 +/- 6.4 bursts.s-1 (plateau ICP 38.6 +/- 1.0 mmHg) and decreased to 34.8 +/- 5.6 bursts.s-1 (post-infusion ICP 9.1 +/- 0.8 mmHg). In patients (n = 10), muscle sympathetic activity increased from 51.2 +/- 2.5 bursts.min-1 (baseline ICP 8.3 +/- 1.0 mmHg) to 66.7 +/- 2.9 bursts.min-1 (plateau ICP 25 +/- 0.3 mmHg) and decreased to 58.8 +/- 2.6 bursts.min-1 (post infusion ICP 14.8 +/- 0.9 mmHg). In patients 7 mmHg ICP rise significantly increases sympathetic activity by 17%. Heart-rate variability analysis demonstrated a significant vagal withdrawal during the ICP rise, in accordance with the microneurography findings. Mice and human results are alike. We demonstrate in animal and human that ICP is a reversible determinant of efferent sympathetic outflow, even at relatively low ICP levels. ICP is a biophysical stress related to the forces within the brain. But ICP has also to be considered as a physiological stressor, driving sympathetic activity. The results suggest a novel physiological ICP-mediated sympathetic modulation circuit and the existence of a possible intracranial (i.e., central) baroreflex. Modest ICP rise might participate to the pathophysiology of cardio-metabolic homeostasis imbalance with sympathetic over-activity, and to the pathogenesis of sympathetically-driven diseases. PMID- 29472866 TI - Hypoxia Exacerbates Negative Emotional State during Inactivity: The Effect of 21 Days Hypoxic Bed Rest and Confinement. AB - Hypoxia and confinement have both been shown to influence emotional state. It is envisaged that the inhabitants of future planetary habitats will be exposed to concomitant confinement, reduced gravity and hypoxia. We examined the independent and combined effects of a 21-day inactivity/unloading and normobaric hypoxia under confined conditions on various psychological factors. Eleven healthy men participated in three 21-day experimental campaigns designed in a cross-over manner: (1) Normobaric hypoxic ambulatory confinement, (2) Normobaric hypoxic bed rest and (3) Normobaric normoxic bed rest. The Profile of Mood States, and the Positive and Negative Affect Schedule were employed to assess the participants' psychological responses before (Pre), during (Day 7, Day 14, and Day 21) and after (Post) the confinements. The most negative psychological profile appeared on days 14 and 21 of the hypoxic bed rest campaign. A significant increase in depression, tension, and confusion was noted on days 14 and 21 of the hypoxic bed rest condition. Concomitantly, a decrease, albeit not statistically significant, in positive psychological responses was observed. The psychological profile returned to the initial level at Post following all confinements. These data suggest that the combined effect of hypoxia and bed rest induced the most negative effects on an individual's mood. However, significant intra- and inter individual differences in psychological responses were noted and should be taken into consideration. PMID- 29472867 TI - Human Milk and Donkey Milk, Compared to Cow Milk, Reduce Inflammatory Mediators and Modulate Glucose and Lipid Metabolism, Acting on Mitochondrial Function and Oleylethanolamide Levels in Rat Skeletal Muscle. AB - Scope: Milk from various species differs in nutrient composition. In particular, human milk (HM) and donkey milk (DM) are characterized by a relative high level of triacylglycerol enriched in palmitic acid in sn-2 position. These dietary fats seem to exert beneficial nutritional properties through N-acylethanolamine tissue modulation. The aim of this study is to compare the effects of cow milk (CM), DM, and HM on inflammation and glucose and lipid metabolism, focusing on mitochondrial function, efficiency, and dynamics in skeletal muscle, which is the major determinant of resting metabolic rate. Moreover, we also evaluated the levels of endocannabinoids and N-acylethanolamines in liver and skeletal muscle, since tissue fatty acid profiles can be modulated by nutrient intervention. Procedures: To this aim, rats were fed with CM, DM, or HM for 4 weeks. Then, glucose tolerance and insulin resistance were analyzed. Pro-inflammatory and anti inflammatory cytokines were evaluated in serum and skeletal muscle. Skeletal muscle was also processed to estimate mitochondrial function, efficiency, and dynamics, oxidative stress, and antioxidant/detoxifying enzyme activities. Fatty acid profiles, endocannabinoids, and N-acylethanolamine congeners were determined in liver and skeletal muscle tissue. Results: We demonstrated that DM or HM administration reducing inflammation status, improves glucose disposal and insulin resistance and reduces lipid accumulation in skeletal muscle. Moreover, HM or DM administration increases redox status, and mitochondrial uncoupling, affecting mitochondrial dynamics in the skeletal muscle. Interestingly, HM and DM supplementation increase liver and muscle levels of the N-oleoylethanolamine (OEA), a key regulator of lipid metabolism and inflammation. Conclusions: HM and DM have a healthy nutritional effect, acting on inflammatory factors and glucose and lipid metabolism. This beneficial effect is associated to a modulation of mitochondrial function, efficiency, and dynamics and to an increase of OEA levels in skeletal muscle. PMID- 29472868 TI - Niemann-Pick C2 Proteins: A New Function for an Old Family. AB - Niemann-Pick proteins type C2 (NPC2) are carriers of cholesterol in vertebrates, with a single member in each species. The high sequence conservation between mammals and across vertebrates is related to their common function. In contrast, NPC2 proteins in arthropods have undergone extensive duplication and differentiation, probably under environmental pressure, and are likely to have different functions. Recent studies have suggested that in arthropods these proteins might act as carriers for semiochemicals and other hydrophobic compounds. In this study we focused on the function of a specific NPC2 gene in the moth Helicoverpa armigera (HarmNPC2-1). This protein binds several flavonoids with micromolar dissociation constants. The best ligand was gossypol, present in cotton, one of the main host plants for H. armigera. Western blot revealed the presence of HarmNPC2-1 in different parts of the body, including the antennae, proboscis, and abdomen. In the antennae, in situ hybridization experiments produced strong staining in auxiliary cells at the base of sensilla trichodea, basiconica, coeloconica, and chaetica. Immunocytochemistry confirmed the expression of the protein in sensilla chaetica. Our results support a role of semiochemical carriers for NPC2 proteins in insects and indicate such proteins as new targets for insecticide-free pest population control. PMID- 29472869 TI - Phosphorylated and Non-phosphorylated Leucine Rich Amelogenin Peptide Differentially Affect Ameloblast Mineralization. AB - The Leucine Rich Amelogenin Peptide (LRAP) is a product of alternative splicing of the amelogenin gene. As full length amelogenin, LRAP has been shown, in precipitation experiments, to regulate hydroxyapatite (HAP) crystal formation depending on its phosphorylation status. However, very few studies have questioned the impact of its phosphorylation status on enamel mineralization in biological models. Therefore, we have analyzed the effect of phosphorylated (+P) or non-phosphorylated (-P) LRAP on enamel formation in ameloblast-like cell lines and ex vivo cultures of murine postnatal day 1 molar germs. To this end, the mineral formed was analyzed by micro-computed tomography, Field Emission Scanning Electron Microscopy, Transmission Electron Microscopy, Selected Area Electon Diffraction imaging. Amelogenin gene transcription was evaluated by qPCR analysis. Our data show that, in both cells and germ cultures, LRAP is able to induce an up-regulation of amelogenin transcription independently of its phosphorylation status. Mineral formation is promoted by LRAP(+P) in all models, while LRAP(-P) essentially affects HAP crystal formation through an increase in crystal length and organization in ameloblast-like cells. Altogether, these data suggest a differential effect of LRAP depending on its phosphorylation status and on the ameloblast stage at the time of treatment. Therefore, LRAP isoforms can be envisioned as potential candidates for treatment of enamel lesions or defects and their action should be further evaluated in pathological models. PMID- 29472870 TI - High-Intensity Interval Training in Normobaric Hypoxia Leads to Greater Body Fat Loss in Overweight/Obese Women than High-Intensity Interval Training in Normoxia. AB - A moderate hypoxic stimulus is considered a promising therapeutic modality for several pathological states including obesity. There is scientific evidence suggesting that when hypoxia and physical activity are combined, they could provide benefits for the obese population. The aim of the present study was to investigate if exposure to hypoxia combined with two different protocols of high intensity interval exercise in overweight/obese women was more effective compared with exercise in normoxia. Study participants included 82 overweight/obese women, who started a 12 week program of 36 sessions, and were randomly divided into four groups: (1) aerobic interval training in hypoxia (AitH; FiO2 = 17.2%; n = 13), (2) aerobic interval training in normoxia (AitN; n = 15), (3) sprint interval training in hypoxia (SitH; n = 15), and (4) sprint interval training in normoxia (SitN; n = 18). Body mass, body mass index, percentage of total fat mass, muscle mass, basal metabolic rate, fat, and carbohydrate oxidation, and fat and carbohydrate energy were assessed. Outcomes were measured at baseline (T1), after 18 training sessions (T2), 7 days after the last session (T3), and 4 weeks after the last session (T4). The fat mass in the SitH group was significantly reduced compared with the SitN group from T1 to T3 (p < 0.05) and from T1 to T4 (p < 0.05) and muscle mass increased significantly from T1 to T4 (p < 0.05). Fat mass in the AitH group decreased significantly (p < 0.01) and muscle mass increased (p = 0.022) compared with the AitN group from T1 to T4. All training groups showed a reduction in the percentage of fat mass, with a statistically significant reduction in the hypoxia groups (p < 0.05). Muscle mass increased significantly in the hypoxia groups (p < 0.05), especially at T4. While fat oxidation tended to increase and oxidation of carbohydrates tended to decrease in both hypoxia groups, the tendency was reversed in the normoxia groups. Thus, high-intensity interval training under normobaric intermittent hypoxia for 12 weeks in overweight/obese women seems to be promising for reducing body fat content with a concomitant increase in muscle mass. PMID- 29472871 TI - A Comparison between Different Methods of Estimating Anaerobic Energy Production. AB - Purpose: The present study aimed to compare four methods of estimating anaerobic energy production during supramaximal exercise. Methods: Twenty-one junior cross country skiers competing at a national and/or international level were tested on a treadmill during uphill (7 degrees ) diagonal-stride (DS) roller-skiing. After a 4-minute warm-up, a 4 * 4-min continuous submaximal protocol was performed followed by a 600-m time trial (TT). For the maximal accumulated O2 deficit (MAOD) method the [Formula: see text]O2-speed regression relationship was used to estimate the [Formula: see text]O2 demand during the TT, either including (4+Y, method 1) or excluding (4-Y, method 2) a fixed Y-intercept for baseline [Formula: see text]O2. The gross efficiency (GE) method (method 3) involved calculating metabolic rate during the TT by dividing power output by submaximal GE, which was then converted to a [Formula: see text]O2 demand. An alternative method based on submaximal energy cost (EC, method 4) was also used to estimate [Formula: see text]O2 demand during the TT. Results: The GE/EC remained constant across the submaximal stages and the supramaximal TT was performed in 185 +/- 24 s. The GE and EC methods produced identical [Formula: see text]O2 demands and O2 deficits. The [Formula: see text]O2 demand was ~3% lower for the 4+Y method compared with the 4-Y and GE/EC methods, with corresponding O2 deficits of 56 +/- 10, 62 +/- 10, and 63 +/- 10 mL.kg-1, respectively (P < 0.05 for 4+Y vs. 4-Y and GE/EC). The mean differences between the estimated O2 deficits were -6 +/- 5 mL.kg-1 (4+Y vs. 4-Y, P < 0.05), -7 +/- 1 mL.kg-1 (4+Y vs. GE/EC, P < 0.05) and -1 +/- 5 mL.kg-1 (4-Y vs. GE/EC), with respective typical errors of 5.3, 1.9, and 6.0%. The mean difference between the O2 deficit estimated with GE/EC based on the average of four submaximal stages compared with the last stage was 1 +/- 2 mL.kg-1, with a typical error of 3.2%. Conclusions: These findings demonstrate a disagreement in the O2 deficits estimated using current methods. In addition, the findings suggest that a valid estimate of the O2 deficit may be possible using data from only one submaximal stage in combination with the GE/EC method. PMID- 29472872 TI - Pharmacoresistant Severe Mental Health Disorders in Children and Adolescents: Functional Abnormalities of Cytochrome P450 2D6. AB - Background: Severe mental health disorders in children and adolescents represent a major public health problem. Despite adequate drug treatment, some patients develop pharmacoresistant disease. As a consequence, physicians are confronted with prescribing challenges, prolonged hospitalization and increased risk of adverse events, thus aggravating short-, medium-, and long-term prognosis. The majority of psychotropic treatments, particularly antipsychotics and antidepressants, are metabolized at hepatic level by cytochrome P450 (CYP), particularly by CYP3A4 and CYP2D6. Several CYP2D6 genetic polymorphisms are described to be associated with ultrarapid (UM) or poor drug metabolism (PM), inducing clinical resistance and/or adverse events, and might therefore be related to pharmacoresistant severe mental health disease. Case presentation: A total of nine pharmacoresistant patients (four females, five males) aged 11-16 (mean 14.1) years have been genotyped for CYP2D6 between January, 2015 and April, 2016. Patients were diagnosed with schizophrenia (n = 5), autism spectrum disorders (n = 2), intellectual disability with challenging behavior (n = 2), oppositional defiant disorder (n = 1), and post-traumatic stress and borderline personality disorders (n = 1). They had a treatment history with on average 6.1 (3-9) psychotropic, 5 (3-7) antipsychotic, and 3.4 (2-5) CYP2D6-metabolized antipsychotic and antidepressant molecules. Five patients (56%) presented functional anomalies of the CYP2D6 gene: three patients were UM metabolizers with gene duplication and two patients were PM with *4/*41 and *3/*4 polymorphisms. Conclusion: Functional anomalies of CYP2D6 concerned more than half of our pediatric inpatient sample with pharmacoresistant disease. However, our case reports are limited by the low sample size. Nevertheless, knowledge of individual metabolism and in particular CYP2D6 genotyping should be considered for clinical workup and therapy adjustment in resistant patients in child and adolescent psychiatry and might permit better treatment outcome, increased treatment adherence and diminished adverse events. PMID- 29472873 TI - Facial Recognition of Happiness Is Impaired in Musicians with High Music Performance Anxiety. AB - Introduction: Music performance anxiety (MPA) can be defined as a lasting and intense apprehension connected with musical performance in public. Studies suggest that MPA can be regarded as a subtype of social anxiety. Since individuals with social anxiety have deficits in the recognition of facial emotion, we hypothesized that musicians with high levels of MPA would share similar impairments. Objective: The aim of this study was to compare parameters of facial emotion recognition (FER) between musicians with high and low MPA. Methods: 150 amateur and professional musicians with different musical backgrounds were assessed in respect to their level of MPA and completed a dynamic FER task. The outcomes investigated were accuracy, response time, emotional intensity, and response bias. Results: Musicians with high MPA were less accurate in the recognition of happiness (p = 0.04; d = 0.34), had increased response bias toward fear (p = 0.03), and increased response time to facial emotions as a whole (p = 0.02; d = 0.39). Conclusion: Musicians with high MPA displayed FER deficits that were independent of general anxiety levels and possibly of general cognitive capacity. These deficits may favor the maintenance and exacerbation of experiences of anxiety during public performance, since cues of approval, satisfaction, and encouragement are not adequately recognized. PMID- 29472874 TI - Validation of the Portuguese Version of Impulsive-Premeditated Aggression Scale in an Inmate Population. AB - Aggression is one of the core symptoms of antisocial personality disorder (ASPD) with therapeutic and prognostic relevance. ASPD is highly prevalent among inmates, being responsible for adverse events and elevated direct and indirect economic costs for the criminal justice system. The Impulsive/Premeditated Aggression Scale (IPAS) is a self-report instrument that characterizes aggression as either predominately impulsive or premeditated. This study aims to determine the validity and reliability of the IPAS in a sample of Portuguese inmates. A total of 240 inmates were included in the study. A principal component factor analysis was performed so as to obtain the construct validity of the IPAS impulsive aggression (IA) and premeditated aggression (PM) subscales; internal consistency was determined by Cronbach's alpha coefficient; convergent and divergent validity of the subscales were determined analyzing correlations with the Barratt Impulsiveness scale, 11th version (BIS-11), and the Psychopathic Checklist Revised (PCL-R). The rotated matrix with two factors accounted for 49.9% of total variance. IA subscale had 11 items and PM subscale had 10 items. The IA and PM subscales had a good Cronbach's alpha values of 0.89 and 0.88, respectively. The IA subscale is correlated with BIS-11 attentional, motor, and non-planning impulsiveness dimensions (p < 0.05). The PM subscale is correlated with BIS-11 attentional, motor impulsiveness dimensions (p < 0.05). The PM subscale is correlated with PCL-R interpersonal, lifestyle, and antisocial dimensions (p < 0.05). The IA subscale is not correlated with PCL-R. The Portuguese translated version of IPAS has adequate psychometric properties, allowing the measurement of impulsive and premeditated dimensions of aggression.

AB - Objective: Comorbidity between personality disorders (PD) and substance-use disorders (SUD) is one of the most common findings in the psychiatric field. The patients with Cluster C disorders present maladjustment traits often characterized by high levels of anxiety. The main aim of this study was to find evidences about higher anxiety and depression prevalence on Cluster C than others Clusters, analyzing similarities and differences within, with other Cluster A and B PD patients and patients without PD. Method: A total of 822 substance dependent patients (ages18-78; Mean = 38.35, SD = 10.14) completed the structured clinical interview for DSM-IV Axis I and Axis II disorders, Beck Depression Inventory, and State-Trait Anxiety Inventory. Results: Results supported poly-consumption in Cluster C patients, being greater alcohol consumption as well as abuse of both stimulants and depressants. Anxiety and depression did not show just one pattern for all patients with SUD-Cluster C PD. There was a relation between anxiety and depression for all the groups except for the Dependent-PD. Conclusion: Interventions should focus on aspects like depression and anxiety more than on the substance consumed. PMID- 29472877 TI - Commentary: Why Your Body Can Jog Your Mind. PMID- 29472876 TI - Psychopathology Assessment Methods Revisited: On Translational Cross-Validation of Clinical Self-Evaluation Scale and fMRI. AB - We present in this article a study design that combines clinical self-assessment scale, simultaneously administered with fMRI data acquisition. We have used a standard block-design with two different conditions. Each active block consisted of four text statements (items), alternating diagnostically specific (DS) blocks comprising items from von Zerssen depression scale and diagnostically neutral (DN) blocks with items from a questionnaire about general interests. All items were rated on four degree Likert scale, and patients provided responses with corresponding four buttons during the fMRI session. Our results demonstrated that in healthy controls, contrasting the two types of stimuli yielded no residual activations, e.g., the DS did not produce significantly different activations compared to the DN stimuli. Furthermore, the correlation analyses did not find a relationship between brain activations and the total score of the DS statements in this group. However, contrasting the DS stimuli to the DN stimuli in the patients produced significant residual activations in several brain regions: right pre- and postcentral gyrus (including right supramarginal gyrus), left middle frontal gyrus, triangular part of the left inferior frontal gyrus and middle temporal gyrus. The left precuneus demonstrated correlations with the patients' DS score. In the between-group comparisons, we found residual activations in the right pre- and postcentral gyrus, right supplementary motor area, medial segment of the right precentral gyrus, right superior parietal lobule, left middle frontal gyrus, left superior frontal gyrus, left occipital pole. Our results confirm the possibility of translational cross-validation of a clinical psychological test (von Zerssen's depression scale) and fMRI. At this stage, however, we can only confirm the sensitivity of the method (its ability to distinguish healthy controls from depressed patients), but we cannot conclude anything about its specificity (distinction from different psychopathology conditions). PMID- 29472878 TI - The Effects of Martial Arts Training on Attentional Networks in Typical Adults. AB - There is substantial evidence that training in Martial Arts is associated with improvements in cognitive function in children; but little has been studied in healthy adults. Here, we studied the impact of extensive training in Martial Arts on cognitive control in adults. To do so, we used the Attention Network Test (ANT) to test two different groups of participants: with at least 2 years of Martial Arts experience, and with no experience with the sport. Participants were screened from a wider sample of over 500 participants who volunteered to participate. 48 participants were selected: 21 in the Martial Arts group (mean age = 19.68) and 27 in the Non-Martial Arts group (mean age = 19.63). The two groups were matched on a number of demographic variables that included Age and BMI, following the results of a previous pilot study where these factors were found to significantly impact the ANT measures. An effect of Martial Arts experience was found on the Alert network, but not the Orienting or Executive ones. More specifically, Martial Artists showed improved performance when alert had to be sustained endogenously, performing more like the control group when an exogenous cue was provided. This result was further confirmed by a negative correlation between number of years of Martial Arts experience and the costs due to the lack of an exogenous cue suggesting that the longer a person takes part in the sport, the better their endogenous alert is. Results are interpreted in the context of the impact of training a particular attentional state in specific neurocognitive pathways. PMID- 29472879 TI - Transdermal Optical Imaging Reveal Basal Stress via Heart Rate Variability Analysis: A Novel Methodology Comparable to Electrocardiography. AB - The present study examined the validity of a novel physiological measurement technology called transdermal optical imaging (TOI) technology at assessing basal stress. This technology conveniently, contactlessly, and remotely measures facial blood flow changes using a conventional digital video camera. We compared data from TOI against the pulse data collected from the FDA approved BIOPAC system. One hundred thirty-six healthy adults participated in the study. We found that TOI measurements of heart rate and heart rate variability (HRV), which reflects basal stress, corresponded strongly to those obtained from BIOPAC. These findings indicate that TOI technology is a viable method to monitor heart rate and HRV not only accurately but also conveniently, contactlessly, and remotely. Further, measures of HRV obtained via TOI serves as a valid index of basal stress. Potential applications of this technology in psychological research and other fields are discussed. PMID- 29472881 TI - Conditional Mediation of Absorptive Capacity and Environment in International Entrepreneurial Orientation of Family Businesses. AB - This study analyzes the effect of conditional mediation of environment-absorptive capacity in international entrepreneurial orientation of family businesses. Results involve data from 218 Spanish family businesses, analyzed with SmartPLS 3.2.7 software. This paper presents a relevant contribution both to the academic field and the performance of family firms, helping to understand the process of transforming international entrepreneurial orientation into a better international performance through absorptive capacity while family businesses invest their efforts in aligning international entrepreneurial orientation and absorptive capacity with international results, bearing in mind the positive moderator effect of environment. The most relevant contribution of this work is to integrate in the same model the mediating effect of the absorption capacity and the moderating effect of the environment: the effect of the international entrepreneurial orientation on the international performance of family businesses improves with the mediation of the absorptive capacity (the variability of international performance goes from 32.5 to 40.6%) and the moderation of the environment (to variability of international performance goes from 40.6 to 45.3%). PMID- 29472880 TI - Chewing Stimulation Reduces Appetite Ratings and Attentional Bias toward Visual Food Stimuli in Healthy-Weight Individuals. AB - Based on the theory of incentive sensitization, the exposure to food stimuli sensitizes the brain's reward circuits and enhances attentional bias toward food. Therefore, reducing attentional bias to food could possibly be beneficial in preventing impulsive eating. The importance of chewing has been increasingly implicated as one of the methods for reducing appetite, however, no studies to investigate the effect of chewing on attentional bias to food. In this study, we investigated whether chewing stimulation (i.e., chewing tasteless gum) reduces attentional bias to food as well as an actual feeding (i.e., ingesting a standardized meal) does. We measured reaction time, gaze direction and gaze duration to assess attentional bias toward food images in pairs of food and non food images that were presented in a visual probe task (Experiment 1, n = 21) and/or eye-tracking task (Experiment 2, n = 20). We also measured appetite ratings using visual analog scale. In addition, we conducted a control study in which the same number of participants performed the identical tasks to Experiments 1 and 2, but the participants did not perform sham feeding with gum chewing/actual feeding between tasks and they took a rest. Two-way ANOVA revealed that after actual feeding, subjective ratings of hunger, preoccupation with food, and desire to eat significantly decreased, whereas fullness significantly increased. Sham feeding showed the same trends, but to a lesser degree. Results of the visual probe task in Experiment 1 showed that both sham feeding and actual feeding reduced reaction time bias significantly. Eye-tracking data showed that both sham and actual feeding resulted in significant reduction in gaze direction bias, indexing initial attentional orientation. Gaze duration bias was unaffected. In both control experiments, one-way ANOVAs showed no significant differences between immediately before and after the resting state for any of the appetite ratings, reaction time bias, gaze direction bias, or gaze duration bias. In conclusion, chewing stimulation reduced subjective appetite and attentional bias to food, particularly initial attentional orientation to food. These findings suggest that chewing stimulation, even without taste, odor, or ingestion, may affect reward circuits and help prevent impulsive eating. PMID- 29472882 TI - The Quiet Eye and Motor Expertise: Explaining the "Efficiency Paradox". AB - It has been consistently reported that experts show longer quiet eye (QE) durations when compared to near-experts and novices. However, this finding is rather paradoxical as motor expertise is characterized by an economization of motor-control processes rather than by a prolongation in response programming, a suggested explanatory mechanism of the QE phenomenon. Therefore, an inhibition hypothesis was proposed that suggests an inhibition of non-optimal task solutions over movement parametrization, which is particularly necessary in experts due to the great extent and high density of their experienced task-solution space. In the current study, the effect of the task-solution space' extension was tested by comparing the QE-duration gains in groups that trained a far-aiming task with a small number (low-extent) vs. a large number (high-extent) of task variants. After an extensive training period of more than 750 trials, both groups showed superior performance in post-test and retention test when compared to pretest and longer QE durations in post-test when compared to pretest. However, the QE durations dropped to baseline values at retention. Finally, the expected additional gain in QE duration for the high-extent group was not found and thus, the assumption of long QE durations due to an extended task-solution space was not confirmed. The findings were (by tendency) more in line with the density explanation of the inhibition hypothesis. This density argument suits research revealing a high specificity of motor skills in experts thus providing worthwhile options for future research on the paradoxical relation between the QE and motor expertise. PMID- 29472883 TI - Belief Shift or Only Facilitation: How Semantic Expectancy Affects Processing of Speech Degraded by Background Noise. AB - Individuals use semantic expectancy - applying conceptual and linguistic knowledge to speech input - to improve the accuracy and speed of language comprehension. This study tested how adults use semantic expectancy in quiet and in the presence of speech-shaped broadband noise at -7 and -12 dB signal-to-noise ratio. Twenty-four adults (22.1 +/- 3.6 years, mean +/-SD) were tested on a four alternative-forced-choice task whereby they listened to sentences and were instructed to select an image matching the sentence-final word. The semantic expectancy of the sentences was unrelated to (neutral), congruent with, or conflicting with the acoustic target. Congruent expectancy improved accuracy and conflicting expectancy decreased accuracy relative to neutral, consistent with a theory where expectancy shifts beliefs toward likely words and away from unlikely words. Additionally, there were no significant interactions of expectancy and noise level when analyzed in log-odds, supporting the predictions of ideal observer models of speech perception. PMID- 29472884 TI - Functional Strength Training and Movement Performance Therapy for Upper Limb Recovery Early Poststroke-Efficacy, Neural Correlates, Predictive Markers, and Cost-Effectiveness: FAST-INdiCATE Trial. AB - Background: Variation in physiological deficits underlying upper limb paresis after stroke could influence how people recover and to which physical therapy they best respond. Objectives: To determine whether functional strength training (FST) improves upper limb recovery more than movement performance therapy (MPT). To identify: (a) neural correlates of response and (b) whether pre-intervention neural characteristics predict response. Design: Explanatory investigations within a randomised, controlled, observer-blind, and multicentre trial. Randomisation was computer-generated and concealed by an independent facility until baseline measures were completed. Primary time point was outcome, after the 6-week intervention phase. Follow-up was at 6 months after stroke. Participants: With some voluntary muscle contraction in the paretic upper limb, not full dexterity, when recruited up to 60 days after an anterior cerebral circulation territory stroke. Interventions: Conventional physical therapy (CPT) plus either MPT or FST for up to 90 min-a-day, 5 days-a-week for 6 weeks. FST was "hands-off" progressive resistive exercise cemented into functional task training. MPT was "hands-on" sensory/facilitation techniques for smooth and accurate movement. Outcomes: The primary efficacy measure was the Action Research Arm Test (ARAT). Neural measures: fractional anisotropy (FA) corpus callosum midline; asymmetry of corticospinal tracts FA; and resting motor threshold (RMT) of motor-evoked potentials. Analysis: Covariance models tested ARAT change from baseline. At outcome: correlation coefficients assessed relationship between change in ARAT and neural measures; an interaction term assessed whether baseline neural characteristics predicted response. Results: 288 Participants had: mean age of 72.2 (SD 12.5) years and mean ARAT 25.5 (18.2). For 240 participants with ARAT at baseline and outcome the mean change was 9.70 (11.72) for FST + CPT and 7.90 (9.18) for MPT + CPT, which did not differ statistically (p = 0.298). Correlations between ARAT change scores and baseline neural values were between 0.199, p = 0.320 for MPT + CPT RMT (n = 27) and -0.147, p = 0.385 for asymmetry of corticospinal tracts FA (n = 37). Interaction effects between neural values and ARAT change between baseline and outcome were not statistically significant. Conclusions: There was no significant difference in upper limb improvement between FST and MPT. Baseline neural measures did not correlate with upper limb recovery or predict therapy response.

PMID- 29472886 TI - Changes in Brain Lateralization in Patients with Mild Cognitive Impairment and Alzheimer's Disease: A Resting-State Functional Magnetic Resonance Study from Alzheimer's Disease Neuroimaging Initiative. AB - Purpose: To detect changes in brain lateralization in patients with mild cognitive impairment (MCI) and Alzheimer's disease (AD) using resting-state functional magnetic resonance imaging (fMRI). Materials and methods: Data from 61 well-matched right-handed subjects were obtained from the Alzheimer's Disease Neuroimaging Initiative, including 19 healthy controls (HCs), 25 patients with MCI, and 17 patients with AD. First, we divided 256 pairs of seed regions from each hemisphere covering the entire cerebral gray matter. Then, we used the intrinsic laterality index (iLI) approach to quantify the functional laterality using fMRI. One-way ANOVA was employed to estimate the differences in iLI among the three groups. The sum, number and mean value of the iLI were calculated within the thresholds of 0 < |iLI| < 0.2, 0.2 <= |iLI| < 0.4, 0.4 <= |iLI| < 0.8, and |iLI| >= 0.8, to explore the changes in the lateralization of resting-state brain function in patients with MCI and AD. Results: One-way ANOVA revealed that the iLIs of the three groups were significantly different. The HCs showed a significant leftward interhemispheric difference within |iLI| >= 0.8. Compared with the HCs, the patients with MCI manifested a distinct abnormal rightward interhemispheric asymmetry, mainly within the thresholds of 0.2 <= |iLI| < 0.4 and 0.4 <= |iLI| < 0.8; in the patients with AD, the normal leftward lateralization that was observed in the HCs disappeared, and an abnormal rightward laterality was expressed within 0.4 <= |iLI| < 0.8. By directly comparing the patients with MCI with the patients with AD, an exclusive abnormal rightward laterality was observed in the patients with MCI within the 0.2 <= |iLI| < 0.4 threshold, and the normal leftward asymmetry vanished in the patients with AD within the |iLI| >= 0.8 threshold. Conclusion: Global brain lateralization was different among three groups. The abnormal rightward dominance observed in the patients with MCI and AD may indicate that these patients use additional brain resources to compensate for the loss of cognitive function, and the observed disappearance of the leftward laterality in the patients with AD was likely associated with the damage in the left hemisphere. The observed disappearance of the rightward asymmetry in the patients with AD using the 0.2 <= |iLI| < 0.4 threshold was likely a sign of decompensation. Our study provides new insights that may improve our understanding of MCI and AD. PMID- 29472887 TI - A Possible Role for Platelet-Activating Factor Receptor in Amyotrophic Lateral Sclerosis Treatment. AB - Amyotrophic lateral sclerosis (ALS) is the third most prevalent neurodegenerative disease affecting upper and lower motor neurons. An important pathway that may lead to motor neuron degeneration is neuroinflammation. Cerebrospinal Fluids of ALS patients have increased levels of the inflammatory cytokine IL-18. Because IL 18 is produced by dendritic cells stimulated by the platelet-activating factor (PAF), a major neuroinflammatory mediator, it is expected that PAF is involved in ALS. Here we show pilot experimental data on amplification of PAF receptor (PAFR) mRNA by RT-PCR. PAFR is overexpressed, as compared to age matched controls, in the spinal cords of transgenic ALS SOD1-G93A mice, suggesting PAF mediation. Although anti-inflammatory drugs have been tested for ALS before, no clinical trial has been conducted using PAFR specific inhibitors. Therefore, we hypothesize that administration of PAFR inhibitors, such as Ginkgolide B, PCA 4248 and WEB 2086, have potential to function as a novel therapy for ALS, particularly in SOD1 familial ALS forms. Because currently there are only two approved drugs with modest effectiveness for ALS therapy, a search for novel drugs and targets is essential. PMID- 29472888 TI - The Effect of Visual Stimuli on Stability and Complexity of Postural Control. AB - Visual input could benefit balance control or increase postural sway, and it is far from fully understanding the effect of visual stimuli on postural stability and its underlying mechanism. In this study, the effect of different visual inputs on stability and complexity of postural control was examined by analyzing the mean velocity (MV), SD, and fuzzy approximate entropy (fApEn) of the center of pressure (COP) signal during quiet upright standing. We designed five visual exposure conditions: eyes-closed, eyes-open (EO), and three virtual reality (VR) scenes (VR1-VR3). The VR scenes were a limited field view of an optokinetic drum rotating around yaw (VR1), pitch (VR2), and roll (VR3) axes, respectively. Sixteen healthy subjects were involved in the experiment, and their COP trajectories were assessed from the force plate data. MV, SD, and fApEn of the COP in anterior-posterior (AP), medial-lateral (ML) directions were calculated. Two-way analysis of variance with repeated measures was conducted to test the statistical significance. We found that all the three parameters obtained the lowest values in the EO condition, and highest in the VR3 condition. We also found that the active neuromuscular intervention, indicated by fApEn, in response to changing the visual exposure conditions were more adaptive in AP direction, and the stability, indicated by SD, in ML direction reflected the changes of visual scenes. MV was found to capture both instability and active neuromuscular control dynamics. It seemed that the three parameters provided compensatory information about the postural control in the immersive virtual environment. PMID- 29472885 TI - The Pathoconnectivity Profile of Alzheimer's Disease: A Morphometric Coalteration Network Analysis. AB - Gray matter alterations are typical features of brain disorders. However, they do not impact on the brain randomly. Indeed, it has been suggested that neuropathological processes can selectively affect certain assemblies of neurons, which typically are at the center of crucial functional networks. Because of their topological centrality, these areas form a core set that is more likely to be affected by neuropathological processes. In order to identify and study the pattern formed by brain alterations in patients' with Alzheimer's disease (AD), we devised an innovative meta-analytic method for analyzing voxel-based morphometry data. This methodology enabled us to discover that in AD gray matter alterations do not occur randomly across the brain but, on the contrary, follow identifiable patterns of distribution. This alteration pattern exhibits a network like structure composed of coaltered areas that can be defined as coatrophy network. Within the coatrophy network of AD, we were able to further identify a core subnetwork of coaltered areas that includes the left hippocampus, left and right amygdalae, right parahippocampal gyrus, and right temporal inferior gyrus. In virtue of their network centrality, these brain areas can be thought of as pathoconnectivity hubs. PMID- 29472889 TI - Clinical and Magnetic Resonance Imaging Findings of Neurotoxocariasis. AB - Human toxocariasis is one of the most prevalent helminthiases worldwide. Toxocara canis larvae can cross the blood-brain barrier leading to the neurotoxocariasis. The clinical presentation consists of a wide spectrum of neurological manifestations, but asymptomatic infection is probably common. Neurotoxocariasis is not a frequent diagnosis probably due to the non-specific nature of its symptoms as well as the lack of confirmatory diagnostic tests. Diagnosis of neurotoxocariasis is based on the presence of a high titer of anti-Toxocara antibody in the cerebrospinal fluid or in the serum, presence of eosinophilia in the serum or cerebrospinal fluid, and clinical and radiological improvement after anthelmintic therapy; however, universally accepted diagnostic criteria are lacking. Magnetic resonance imaging (MRI) findings include single or multiple, subcortical, cortical or white matter hyperintense lesions, best visualized on FLAIR and T2-weighted imaging, and usually isointense or hypointense on T1. These imaging findings are suggestive but not specific to neurotoxocariasis. Definitive diagnosis is made by histological confirmation, but it is rarely followed. This review provides an overview of the clinical manifestations, management options, and MRI findings of neurotoxocariasis. PMID- 29472890 TI - Severe Blood-Brain Barrier Disruption in Cardioembolic Stroke. AB - Background: Previous studies demonstrated that cardioembolism (CE) was prone to develop hemorrhagic transformation (HT), whereas hyper-permeability of blood brain barrier (BBB) might be one reason for the development of HT. We, thus, aimed to investigate whether the BBB permeability (BBBP) was higher in CE stroke than other stroke subtypes in acute ischemic stroke (AIS) patients. Methods: This study was a retrospective review of prospectively collected clinical and imaging database of AIS patients who underwent CT perfusion. Hypoperfusion was defined as Tmax >6 s. The average relative permeability-surface area product (rPS), reflecting the BBBP, was calculated within the hypoperfusion region (rPShypo). CE was diagnosed according to the international Trial of Org 10172 in Acute Stroke Treatment criteria. Receiver operating characteristics (ROC) curve analysis was used to determine predictive value of rPShypo for CE. Logistic regression was used to identify independent predictors for CE. Results: A total of 187 patients were included in the final analysis [median age, 73 (61-80) years; 75 (40.1%) females; median baseline National Institutes of Health Stroke Scale score, 12 (7 16)]. Median rPShypo was 65.5 (35.8-110.1)%. Ninety-seven (51.9%) patients were diagnosed as CE. ROC analysis revealed that the optimal rPShypo threshold for CE was 86.71%. The value of rPShypo and the rate of rPShypo>86.71% were significantly higher in patients with CE than other stroke subtypes (p < 0.05), after adjusting for the potential confounds. Conclusion: The extent of BBB disruption is more severe in CE stroke than other stroke subtypes during the hyperacute stage. PMID- 29472891 TI - A Review of Traumatic Axonal Injury following Whiplash Injury As Demonstrated by Diffusion Tensor Tractography. AB - Whiplash is a bony or soft tissue injury resulting from an acceleration deceleration energy transfer in the neck. Although patients with whiplash injury often complain of cerebral symptoms, and previous studies have reported evidence indicating brain injury, such an association has not been clearly elucidated. Traumatic axonal injury (TAI) is tearing of axons due to indirect shearing forces during acceleration, deceleration, and rotation of the brain or to direct head trauma. Diffusion tensor imaging (DTI) has a unique advantage to detect TAI in patients whose conventional brain CT or magnetic resonance imaging (MRI) results were negative following head trauma. Since the introduction of DTI, six studies using diffusion tensor tractography (DTT) based on DTI data have reported TAI in patients with whiplash injury, even though conventional brain CT or MRI results were negative. A precise TAI diagnosis in whiplash patients is clinically important for proper management and prognosis. Among the methods employed to diagnose TAI in the six previous studies, the common diagnostic approach for neural tract TAI in individual patients with whiplash injury were (1) whiplash injury history due to car accident; (2) development of new clinical symptoms and signs after whiplash injury; (3) evidence of neural tract TAI in DTT results, mainly via configurational analysis; and (4) coincidence of newly developed clinical manifestations and the function of injured neural tracts. All six studies were individual patient case studies; therefore, further prospective studies involving larger number of subjects should be encouraged. PMID- 29472892 TI - Maternal and Cord Blood Vitamin D Status and Anthropometric Measurements in Term Newborns at Birth. AB - Introduction: Vitamin D deficiency in pregnant women may result in reduced neonatal development due to the fact that systemic vitamin D status during fetal life depends on maternal concentrations. Some authors reported significant differences in neonatal anthropometric measurements depending on maternal vitamin D concentrations. Objective: The aim of this study is to evaluate the relationship between maternal and cord blood concentrations of vitamin D and neonatal anthropometric measurements at birth. Materials and methods: This study included 94 pregnant women, at term, who delivered at the Department of Obstetrics, Women's Diseases and Gynecological Oncology, Medical University of Warsaw. Total serum 25(OH)D concentration was measured in mother-child pairs, and newborn anthropometric data were collected. A multiple regression analysis was used for statistical analysis. Results: No relationship between maternal and neonatal cord blood vitamin D concentrations vs. neonatal weight, length, head, and chest circumference at birth was found (p > 0.05). Severe vitamin D deficiency (<10 ng/ml) was detected in 10.6%, deficiency (10-20 ng/ml) in 39.4%, insufficiency (20-30 ng/ml) in 39.4%, and optimal vitamin D concentration (>30 ng/ml) only in 10.6% of the pregnant women. Cord blood vitamin D deficiency (<20 ng/ml) was found in 28.7% of the neonates. Conclusion: No differences between neonatal anthropometric measurements of infants born to mothers with normal and deficient vitamin D concentrations were found. PMID- 29472894 TI - Photosynthesis Is Widely Distributed among Proteobacteria as Demonstrated by the Phylogeny of PufLM Reaction Center Proteins. AB - Two different photosystems for performing bacteriochlorophyll-mediated photosynthetic energy conversion are employed in different bacterial phyla. Those bacteria employing a photosystem II type of photosynthetic apparatus include the phototrophic purple bacteria (Proteobacteria), Gemmatimonas and Chloroflexus with their photosynthetic relatives. The proteins of the photosynthetic reaction center PufL and PufM are essential components and are common to all bacteria with a type-II photosynthetic apparatus, including the anaerobic as well as the aerobic phototrophic Proteobacteria. Therefore, PufL and PufM proteins and their genes are perfect tools to evaluate the phylogeny of the photosynthetic apparatus and to study the diversity of the bacteria employing this photosystem in nature. Almost complete pufLM gene sequences and the derived protein sequences from 152 type strains and 45 additional strains of phototrophic Proteobacteria employing photosystem II were compared. The results give interesting and comprehensive insights into the phylogeny of the photosynthetic apparatus and clearly define Chromatiales, Rhodobacterales, Sphingomonadales as major groups distinct from other Alphaproteobacteria, from Betaproteobacteria and from Caulobacterales (Brevundimonas subvibrioides). A special relationship exists between the PufLM sequences of those bacteria employing bacteriochlorophyll b instead of bacteriochlorophyll a. A clear phylogenetic association of aerobic phototrophic purple bacteria to anaerobic purple bacteria according to their PufLM sequences is demonstrated indicating multiple evolutionary lines from anaerobic to aerobic phototrophic purple bacteria. The impact of pufLM gene sequences for studies on the environmental diversity of phototrophic bacteria is discussed and the possibility of their identification on the species level in environmental samples is pointed out. PMID- 29472893 TI - Late-Onset Puberty Induction by Transdermal Estrogen in Turner Syndrome Girls-A Longitudinal Study. AB - Objective: Estrogen replacement therapy (ERT) for Turner syndrome (TS) is a widely discussed topic; however, the optimal model of ERT for patients with delayed diagnosis and/or initiation of therapy is still unclear, mainly due to insufficient data. We present the results of a prospective observational single center study in which the efficacy of late-onset puberty induction by one-regimen transdermal ERT in TS girls was evaluated. Methods: The analysis encompassed 49 TS girls (63.3% with 45,X) with hypergonadotropic hypogonadism in whom unified transdermal ERT protocol was used for puberty induction (first two months 12.5 MUg/24 h, thereafter 25.0 MUg/24 h until breakthrough bleeding). Clinical visits for examination and therapy modification took place every 3-6 months. Transabdominal pelvic ultrasound examinations were performed at least twice: at the beginning and at the end of follow-up. Results: The mean (SD) age at ERT induction was 15.1 (1.3) years. The duration of follow-up was 2.4 (1.1) years. Half of all the patients had at least B2 after 0.57 years, B3 after 1.1 years, B4 after 1.97 years, and menarche after 1.82 years from ERT initiation. With earlier initiation of ERT (<=14 years), B2 (p = 0.059) was achieved faster and B4 (p = 0.018) significantly slower than with the later start of ERT. Thirty-four (94.4%) patients had at least stage B3 at menarche. The karyotype, initial weight, and body mass index had no impact on puberty tempo during ERT. The uterine volume increased significantly during ERT in all the study group (p < 0.0001), and in half of the patients, the increase was at least 12.4-fold. It did not correlate with the duration of treatment (p = 0.84) or the dose of estradiol per kilogram (p = 0.78), nor did it depend on karyotype (p = 0.71) or age at ERT initiation (p = 0.28). There were no differences in DeltahSDS during ERT (p = 0.63) between the two age groups (ERT <=14 and >14 years). Conclusion: The presented easy-to-use fixed-dose regimen for late-onset puberty induction allowed for a satisfactory rate of achieving subsequent puberty stages and did not influence the growth potential.

G. lamblia, G. intestinalis) is the protozoan parasite responsible for giardiasis, the most common and widely spread intestinal parasitic disease worldwide, affecting both humans and animals. After cysts ingestion (through either contaminated food or water), Giardia excysts in the upper intestinal tract to release replicating trophozoites that are responsible for the production of symptoms. In the gut, Giardia cohabits with the host's microbiota, and several studies have revealed the importance of this gut ecosystem and/or some probiotic bacteria in providing protection against G. duodenalis infection through mechanisms that remain incompletely understood. Recent findings suggest that Bile-Salt-Hydrolase (BSH)-like activities from the probiotic strain of Lactobacillus johnsonii La1 may contribute to the anti giardial activity displayed by this strain. Here, we cloned and expressed each of the three bsh genes present in the L. johnsonii La1 genome to study their enzymatic and biological properties. While BSH47 and BSH56 were expressed as recombinant active enzymes, no significant enzymatic activity was detected with BSH12. In vitro assays allowed determining the substrate specificities of both BSH47 and BSH56, which were different. Modeling of these BSHs indicated a strong conservation of their 3-D structures despite low conservation of their primary structures. Both recombinant enzymes were able to mediate anti-giardial biological activity against Giardia trophozoites in vitro. Moreover, BSH47 exerted significant anti-giardial effects when tested in a murine model of giardiasis. These results shed new light on the mechanism, whereby active BSH derived from the probiotic strain Lactobacillus johnsonii La1 may yield anti giardial effects in vitro and in vivo. These findings pave the way toward novel approaches for the treatment of this widely spread but neglected infectious disease, both in human and in veterinary medicine. PMID- 29472896 TI - Bacterial Therapy of Cancer: Promises, Limitations, and Insights for Future Directions. AB - Spontaneous tumors regression has been associated with microbial infection for 100s of years and inspired the use of bacteria for anticancer therapy. Dr. William B. Coley (1862-1936), a bone- sarcoma surgeon, was a pioneer in treating his patients with both live bacterial-based and mixture of heat-killed bacteria known as "Coley's toxins." Unfortunately, Coley was forced to stop his work which interrupted this field for about half a century. Currently, several species of bacteria are being developed against cancer. The bacterial species, their genetic background and their infectious behavior within the tumor microenvironment are thought to be relevant factors in determining their anti-tumor effectiveness in vivo. In this perspective article we will update the most promising results achieved using bacterial therapy (alone or combined with other strategies) in clinically-relevant animal models of cancer and critically discuss the impact of the bacterial variants, route of administration and mechanisms of bacteria-cancer cell interaction. We will also discuss strategies to apply this information using modern mouse models, molecular biology, genetics and imaging for future bacterial therapy of cancer patients. PMID- 29472897 TI - Microbial Community Structure and Function Indicate the Severity of Chromium Contamination of the Yellow River. AB - The Yellow River is the most important water resource in northern China. In the recent past, heavy metal contamination has become severe due to industrial processes and other anthropogenic activities. In this study, riparian soil samples with varying levels of chromium (Cr) pollution severity were collected along the Gansu industrial reach of the Yellow River, including samples from uncontaminated sites (XC, XGU), slightly contaminated sites (LJX, XGD), and heavily contaminated sites (CG, XG). The Cr concentrations of these samples varied from 83.83 mg?kg-1 (XGU) to 506.58 mg?kg-1 (XG). The chromate [Cr (VI)] reducing ability in the soils collected in this study followed the sequence of the heavily contaminated > slightly contaminated > the un-contaminated. Common Cr remediation genes chrA and yieF were detected in the XG and CG samples. qRT-PCR results showed that the expression of chrA was up-regulated four and threefold in XG and CG samples, respectively, whereas the expression of yieF was up-regulated 66- and 7-fold in the same samples after 30 min treatment with Cr (VI). The copy numbers of chrA and yieF didn't change after 35 days incubation with Cr (VI). The microbial communities in the Cr contaminated sampling sites were different from those in the uncontaminated samples. Especially, the relative abundances of Firmicutes and Bacteroidetes were higher while Actinobacteria was lower in the contaminated group than uncontaminated group. Further, potential indicator species, related to Cr such as Cr-remediation genera (Geobacter, PSB-M-3, Flavobacterium, and Methanosarcina); the Cr-sensitive genera (Skermanella, Iamia, Arthrobacter, and Candidatus Nitrososphaera) were also identified. These data revealed that Cr shifted microbial composition and function. Further, Cr (VI) reducing ability could be related with the expression of Cr remediation genes. PMID- 29472898 TI - Microbial Diversity and Mineralogical-Mechanical Properties of Calcitic Cave Speleothems in Natural and in Vitro Biomineralization Conditions. AB - Natural mineral formations are a window into important processes leading to carbon storage and mineralized carbonate structures formed through abiotic and biotic processes. In the current study, we made an attempt to undertake a comprehensive approach to characterize the mineralogical, mechanical, and microbial properties of different kinds of speleothems from karstic caves; with an aim to understand the bio-geo-chemical processes in speleothem structures and their impact on nanomechanical properties. We also investigated the biomineralization abilities of speleothem surface associated microbial communities in vitro. Mineralogical profiling using techniques such as X-ray powder Diffraction (XRD) and Tescan Integrated Mineral Analyzer (TIMA) demonstrated that calcite was the dominant mineral in the majority of speleothems with Energy Dispersive X-ray Analysis (EDS) indicating a few variations in the elemental components. Differing proportions of polymorphs of calcium carbonate such as aragonite and vaterite were also recorded. Significant variations in trace metal content were recorded through Inductively Coupled Plasma Mass Spectrometer (ICP-MS). Scanning Electron Microscopy (SEM) analysis revealed differences in morphological features of the crystals which varied from triangular prismatic shapes to etched spiky forms. Microbial imprints and associations were seen in a few sections. Analysis of the associated microbial diversity showed significant differences between various speleothems at Phylum level; although Proteobacteria and Actinobacteria were found to be the predominant groups. Genus level microbial associations showed a relationship with the geochemistry, mineralogical composition, and metal content of the speleothems. The assessment of nanomechanical properties measured by Nanoindentation revealed that the speleothems with a dominance of calcite were stronger than the speleothems with mixed calcium carbonate polymorphs and silica content. The in vitro metabolic activity of the microbial communities associated with the surfaces of the speleothems resulted in calcium carbonate crystal precipitation. Firmicutes and Proteobacteria dominated these populations, in contrast to the populations seen in natural systems. The precipitation of calcium carbonate crystals in vitro indicated that microbial metabolic activity may also play an important role in the synthesis and dissociation of biominerals in the natural environment. Our study provides novel evidence of the close relationship between mineralogy, microbial ecology, geochemistry, and nanomechanical properties of natural formations. PMID- 29472899 TI - Exposure to Sub-lethal 2,4-Dichlorophenoxyacetic Acid Arrests Cell Division and Alters Cell Surface Properties in Escherichia coli. AB - Escherichia coli is a robust, easily adaptable and culturable bacterium in vitro, and a model bacterium for studying the impact of xenobiotics in the environment. We have used correlative atomic force - laser scanning confocal microscopy (AFM LSCM) to characterize the mechanisms of cellular response to the herbicide 2,4 dichlorophenoxyacetic acid (2,4-D). One of the most extensively used herbicides world-wide, 2,4-D is known to cause hazardous effects in diverse non-target organisms. Sub-lethal concentrations of 2,4-D caused DNA damage in E. coli WM1074 during short exposure periods which increased significantly over time. In response to 2,4-D, FtsZ and FtsA relocalized within seconds, coinciding with the complete inhibition of cell septation and cell elongation. Exposure to 2,4-D also resulted in increased activation of the SOS response. Changes to cell division were accompanied by concomitant changes to surface roughness, elasticity and adhesion in a time-dependent manner. This is the first study describing the mechanistic details of 2,4-D at sub-lethal levels in bacteria. Our study suggests that 2,4-D arrests E. coli cell division within seconds after exposure by disrupting the divisome complex, facilitated by dissipation of membrane potential. Over longer exposures, 2,4-D causes filamentation as a result of an SOS response to oxidative stress induced DNA damage. PMID- 29472900 TI - Spatial Heterogeneity and Co-occurrence of Mucosal and Luminal Microbiome across Swine Intestinal Tract. AB - Pigs are one of the most important economic livestock. Gut microbiota is not only critical to the health but also the production efficiency of pigs. Manipulating gut microbiota relies on the full view of gut microbiome and the understanding of drive forces shaping microbial communities. 16s rDNA sequencing was used to profile microbiota along the longitudinal and radical axes to obtain the topographical map of microbiome in different intestinal compartments in young pigs. Alpha and beta-diversities revealed distinct differences in microbial compositions between the distal ileum and cecum and colon, as well as between the lumen and mucosa. Firmicutes and Proteobacteria dominated in the ileum, constituting 95 and 80% of the luminal and mucosa-attached microbiome. Transitioning from the small intestine to the large intestine, luminal Bacteroidetes increased from 1.69 to 45.98% in the cecum and 40.09% in the colon, while mucosal Bacteroidetes raised from 9 to 35.36% and 27.96%. Concurrently, luminal Firmicutes and Proteobacteria and mucosal-attached Proteobacteria remarkably decreased. By co-occurrence network analyses, Prevotellaceae, Ruminococcaceae, Lachnospiraceae and Veillonellaceae were recognized as the central nodes of luminal microbial network, and Prevotellaceae and Enterobacteriaceae, Caulobacteraceae, Enterococcaceae, Xanthomonadaceae, Pseudomonadaceae were identified as mucosal central nodes. Co-abundance was uncovered among Prevotellaceae, Lachnospiraceae, and Veillonellaceae in the luminal and mucosal microbiome, while opportunistic pathogens from gamma Proteobacteria in the mucosa. Strong co-exclusion was shown between Enterobacteriaceae with Prevotellaceae-centered microbial groups in the lumen. Redundancy analysis found bile acids and short chain fatty acids explained 37.1 and 41% of variations in the luminal microbial composition, respectively. Primary bile acid, taurine- and glycine- conjugated bile acids were positively correlated with Lactobacillaceae, Enterobacteriaceae, Clostridiaceae_1, Peptostreptococcaceae, whereas secondary bile acids, acetate, propionate, butyrate, and valerate were positively correlated with Prevotellaceae, Acidaminococcaceae, Ruminococcaceae, Lachnospiraceae, Desulfovibronaceae, Veillonellaceae. Functional analyses demonstrated that Prevotella, Veillonellaceae, Lachnospiraceae, and Ruminococcaceae were positively correlated with gene functions related to amino acids, energy, cofactors and vitamins metabolism, which are indispensable for the hosts. These results suggested site specific colonization and co-occurrence of swine gut microbiome closely relate to the microenvironment in each niche. Interactions of core gut microbiome greatly contributed to metabolism and/or immunity in the swine intestine. PMID- 29472901 TI - New Aspects on Listeria monocytogenes ST5-ECVI Predominance in a Heavily Contaminated Cheese Processing Environment. AB - The eradication of Listeria monocytogenes from food chains is still a great challenge for the food industry and control authorities since some clonal complexes (CCs) are either better adapted to food processing environments (FPEs) or are globally widespread. In this work, we focus on the in-house evolution of L. monocytogenes genotypes collected from a heavily contaminated FPE whose contamination pattern underwent a massive and yet unexplained change. At the beginning of the sampling in 2010, a high variety of most likely transient L. monocytogenes genotypes was detected belonging to sequence type (ST) 1, ST7, ST21, ST37. After several efforts to intensify the hygiene measures, the variability was reduced to L. monocytogenes ST5 that was dominant in the following years 2011 and 2012. We aimed to elucidate possible genetic mechanisms responsible for the high abundance and persistence of ST5 strains in this FPE. Therefore, we compared the genomes of six L. monocytogenes ST5 strains to the less frequently occurring transient L. monocytogenes ST37 and ST204 from the same FPE as well as the highly abundant ST1 and ST21 isolated in 2010. Whole genome analysis indicated a high degree of conservation among ST5 strains [average nucleotide identity (ANI) 99.93-99.99%; tetranucleotide correlation 0.99998 0.99999]. Slight differences in pulsed field gel electrophoresis (PFGE) patterns of two ST5 isolates could be explained by genetic changes in the tRNA-Arg-TCT prophages. ST5 and ST204 strains harbored virtually identical 91 kbp plasmids related to plasmid group 2 (pLM80 and pLMUCDL175). Interestingly, highly abundant genotypes present in the FPE in 2010 did not harbor any plasmids. The ST5 plasmids harbored an efflux pump system (bcrABC cassette) and heavy metal resistance genes possibly providing a higher tolerance to disinfectants. The pLM80 prototype plasmids most likely provide important genetic determinants for a better survival of L. monocytogenes in the FPE. We reveal short-term evolution of L. monocytogenes strains within the same FPE over a 3 year period and our results suggest that plasmids are important for the persistence of ST5 strains in this FPE. PMID- 29472903 TI - Bile Salt Hydrolase Activities: A Novel Target to Screen Anti-Giardia Lactobacilli? AB - Giardia duodenalis is a protozoan parasite responsible for giardiasis, a disease characterized by intestinal malabsorption, diarrhea and abdominal pain in a large number of mammal species. Giardiasis is one of the most common intestinal parasitic diseases in the world and thus a high veterinary, and public health concern. It is well-established that some probiotic bacteria may confer protection against this parasite in vitro and in vivo and we recently documented the implication of bile-salt hydrolase (BSH)-like activities from strain La1 of Lactobacillus johnsonii as mediators of these effects in vitro. We showed that these activities were able to generate deconjugated bile salts that were toxic to the parasite. In the present study, a wide collection of lactobacilli strains from different ecological origins was screened to assay their anti-giardial effects. Our results revealed that the anti-parasitic effects of some of the strains tested were well-correlated with the expression of BSH-like activities. The two most active strains in vitro, La1 and Lactobacillus gasseri CNCM I-4884, were then tested for their capacity to influence G. duodenalis infection in a suckling mice model. Strikingly, only L. gasseri CNCM I-4884 strain was able to significantly antagonize parasite growth with a dramatic reduction of the trophozoites load in the small intestine. Moreover, this strain also significantly reduced the fecal excretion of Giardia cysts after 5 days of treatment, which could contribute to blocking the transmission of the parasite, in contrast of La1 where no effect was observed. This study represents a step toward the development of new prophylactic strategies to combat G. duodenalis infection in both humans and animals. PMID- 29472904 TI - Metabolic and Genetic Properties of Petriella setifera Precultured on Waste. AB - Although fungi that belong to Petriella genus are considered to be favorable agents in the process of microbial decomposition or as plant endophytes, they may simultaneously become plant pests. Hence, nutrition factors are supposed to play an important role. Therefore, it was hypothesized that Petriella setifera compost isolates, precultured on three different waste-based media containing oak sawdust, beet pulp (BP) and wheat bran (WB) will subsequently reveal different metabolic properties and shifts in genetic fingerprinting. In fact, the aim was to measure the influence of selected waste on the properties of P. setifera. The metabolic potential was evaluated by the ability of five P. setifera strains to decompose oak sawdust, BP and WB following the MT2 plate(r) method and the catabolic abilities of the fungus to utilize the carbon compounds located on filamentous fungi (FF) plates(r). Genetic diversity was evaluated using Amplified Fragment Length Polymorphism analysis performed both on DNA sequences and on transcript-derived fragments. P. setifera isolates were found to be more suitable for decomposing waste materials rich in protein, N, P, K and easily accessible sugars (as found in WB and BP), than those rich in lignocellulose (oak sawdust). Surprisingly, among the different waste media, lignocellulose-rich sawdust-based culture chiefly triggered changes in the metabolic and genetic features of P. setifera. Most particularly, it contributed to improvements in the ability of the fungus to utilize waste-substrates in MT2 plate(r) and two times increase the ability to catabolize carbon compounds located in FF plates(r). Expressive metabolic properties resulting from being grown in sawdust-based substrate were in accordance with differing genotype profiles but not transcriptome. Intraspecific differences among P. setifera isolates are described. PMID- 29472902 TI - Prevention and Control Strategies to Counter Zika Virus, a Special Focus on Intervention Approaches against Vector Mosquitoes-Current Updates. AB - Zika virus (ZIKV) is the most recent intruder that acquired the status of global threat creating panic and frightening situation to public owing to its rapid spread, attaining higher virulence and causing complex clinical manifestations including microcephaly in newborns and Guillain Barre Syndrome. Alike other flaviviruses, the principal mode of ZIKV transmission is by mosquitoes. Advances in research have provided reliable diagnostics for detecting ZIKV infection, while several drug/therapeutic targets and vaccine candidates have been identified recently. Despite these progresses, currently there is neither any effective drug nor any vaccine available against ZIKV. Under such circumstances and to tackle the problem at large, control measures of which mosquito population control need to be strengthened following appropriate mechanical, chemical, biological and genetic control measures. Apart from this, several other known modes of ZIKV transmission which have gained importance in recent past such as intrauterine, sexual intercourse, and blood-borne spread need to be checked and kept under control by adopting appropriate precautions and utmost care during sexual intercourse, blood transfusion and organ transplantation. The virus inactivation by pasteurization, detergents, chemicals, and filtration can effectively reduce viral load in plasma-derived medicinal products. Added to this, strengthening of the surveillance and monitoring of ZIKV as well as avoiding travel to Zika infected areas would aid in keeping viral infection under check. Here, we discuss the salient advances in the prevention and control strategies to combat ZIKV with a focus on highlighting various intervention approaches against the vector mosquitoes of this viral pathogen along with presenting an overview regarding human intervention measures to counter other modes of ZIKV transmission and spread. Additionally, owing to the success of vaccines for a number of infections globally, a separate section dealing with advances in ZIKV vaccines and transmission blocking vaccines has also been included. PMID- 29472905 TI - 1-((2,4-Dichlorophenethyl)Amino)-3-Phenoxypropan-2-ol Kills Pseudomonas aeruginosa through Extensive Membrane Damage. AB - The ever increasing multidrug-resistance of clinically important pathogens and the lack of novel antibiotics have resulted in a true antibiotic crisis where many antibiotics are no longer effective. Further complicating the treatment of bacterial infections are antibiotic-tolerant persister cells. Besides being responsible for the recalcitrant nature of chronic infections, persister cells greatly contribute to the observed antibiotic tolerance in biofilms and even facilitate the emergence of antibiotic resistance. Evidently, eradication of these persister cells could greatly improve patient outcomes and targeting persistence may provide an alternative approach in combatting chronic infections. We recently characterized 1-((2,4-dichlorophenethyl)amino)-3-phenoxypropan-2-ol (SPI009), a novel anti-persister molecule capable of directly killing persisters from both Gram-negative and Gram-positive pathogens. SPI009 potentiates antibiotic activity in several in vitro and in vivo infection models and possesses promising anti-biofilm activity. Strikingly, SPI009 restores antibiotic sensitivity even in resistant strains. In this study, we investigated the mode of action of this novel compound using several parallel approaches. Genetic analyses and a macromolecular synthesis assays suggest that SPI009 acts by causing extensive membrane damage. This hypothesis was confirmed by liposome leakage assay and membrane permeability studies, demonstrating that SPI009 rapidly impairs the bacterial outer and inner membranes. Evaluation of SPI009-resistant mutants, which only could be generated under severe selection pressure, suggested a possible role for the MexCD-OprJ efflux pump. Overall, our results demonstrate the extensive membrane-damaging activity of SPI009 and confirm its clinical potential in the development of novel anti-persister therapies. PMID- 29472906 TI - The DNA Methylome of the Hyperthermoacidophilic Crenarchaeon Sulfolobus acidocaldarius. AB - DNA methylation is the most common epigenetic modification observed in the genomic DNA (gDNA) of prokaryotes and eukaryotes. Methylated nucleobases, N6 methyl-adenine (m6A), N4-methyl-cytosine (m4C), and 5-methyl-cytosine (m5C), detected on gDNA represent the discrimination mark between self and non-self DNA when they are part of restriction-modification systems in prokaryotes (Bacteria and Archaea). In addition, m5C in Eukaryotes and m6A in Bacteria play an important role in the regulation of key cellular processes. Although archaeal genomes present modified bases as in the two other domains of life, the significance of DNA methylations as regulatory mechanisms remains largely uncharacterized in Archaea. Here, we began by investigating the DNA methylome of Sulfolobus acidocaldarius. The strategy behind this initial study entailed the use of combined digestion assays, dot blots, and genome resequencing, which utilizes specific restriction enzymes, antibodies specifically raised against m6A and m5C and single-molecule real-time (SMRT) sequencing, respectively, to identify DNA methylations occurring in exponentially growing cells. The previously identified restriction-modification system, specific of S. acidocaldarius, was confirmed by digestion assay and SMRT sequencing while, the presence of m6A was revealed by dot blot and identified on the characteristic Dam motif by SMRT sequencing. No m5C was detected by dot blot under the conditions tested. Furthermore, by comparing the distribution of both detected methylations along the genome and, by analyzing DNA methylation profiles in synchronized cells, we investigated in which cellular pathways, in particular the cell cycle, this m6A methylation could be a key player. The analysis of sequencing data rejected a role for m6A methylation in another defense system and also raised new questions about a potential involvement of this modification in the regulation of other biological functions in S. acidocaldarius. PMID- 29472907 TI - Regulation of Effector Delivery by Type III Secretion Chaperone Proteins in Erwinia amylovora. AB - Type III secretion (TTS) chaperones are critical for the delivery of many effector proteins from Gram-negative bacterial pathogens into host cells, functioning in the stabilization and hierarchical delivery of the effectors to the type III secretion system (TTSS). The plant pathogen Erwinia amylovora secretes at least four TTS effector proteins: DspE, Eop1, Eop3, and Eop4. DspE specifically interacts with the TTS chaperone protein DspF, which stabilizes the effector protein in the cytoplasm and promotes its efficient translocation through the TTSS. However, the role of E. amylovora chaperones in regulating the delivery of other secreted effectors is unknown. In this study, we identified functional interactions between the effector proteins DspE, Eop1, and Eop3 with the TTS chaperones DspF, Esc1 and Esc3 in yeast. Using site-directed mutagenesis, secretion, and translocation assays, we demonstrated that the three TTS chaperones have additive roles for the secretion and translocation of DspE into plant cells whereas DspF negatively affects the translocation of Eop1 and Eop3. Collectively, these results indicate that TTS chaperone proteins exhibit a cooperative behavior to orchestrate the effector secretion and translocation dynamics in E. amylovora. PMID- 29472909 TI - Metagenomic Profiling of Soil Microbes to Mine Salt Stress Tolerance Genes. AB - Osmotolerance is one of the critical factors for successful survival and colonization of microbes in saline environments. Nonetheless, information about these osmotolerance mechanisms is still inadequate. Exploration of the saline soil microbiome for its community structure and novel genetic elements is likely to provide information on the mechanisms involved in osmoadaptation. The present study explores the saline soil microbiome for its native structure and novel genetic elements involved in osmoadaptation. 16S rRNA gene sequence analysis has indicated the dominance of halophilic/halotolerant phylotypes affiliated to Proteobacteria, Actinobacteria, Gemmatimonadetes, Bacteroidetes, Firmicutes, and Acidobacteria. A functional metagenomics approach led to the identification of osmotolerant clones SSR1, SSR4, SSR6, SSR2 harboring BCAA_ABCtp, GSDH, STK_Pknb, and duf3445 genes. Furthermore, transposon mutagenesis, genetic, physiological and functional studies in close association has confirmed the role of these genes in osmotolerance. Enhancement in host osmotolerance possibly though the cytosolic accumulation of amino acids, reducing equivalents and osmolytes involving BCAA ABCtp, GSDH, and STKc_PknB. Decoding of the genetic elements prevalent within these microbes can be exploited either as such for ameliorating soils or their genetically modified forms can assist crops to resist and survive in saline environment. PMID- 29472908 TI - Mining Halophytes for Plant Growth-Promoting Halotolerant Bacteria to Enhance the Salinity Tolerance of Non-halophytic Crops. AB - Salinity stress is one of the major abiotic stresses limiting crop production in arid and semi-arid regions. Interest is increasing in the application of PGPRs (plant growth promoting rhizobacteria) to ameliorate stresses such as salinity stress in crop production. The identification of salt-tolerant, or halophilic, PGPRs has the potential to promote saline soil-based agriculture. Halophytes are a useful reservoir of halotolerant bacteria with plant growth-promoting capabilities. Here, we review recent studies on the use of halophilic PGPRs to stimulate plant growth and increase the tolerance of non-halophytic crops to salinity. These studies illustrate that halophilic PGPRs from the rhizosphere of halophytic species can be effective bio-inoculants for promoting the production of non-halophytic species in saline soils. These studies support the viability of bioinoculation with halophilic PGPRs as a strategy for the sustainable enhancement of non-halophytic crop growth. The potential of this strategy is discussed within the context of ensuring sustainable food production for a world with an increasing population and continuing climate change. We also explore future research needs for using halotolerant PGPRs under salinity stress. PMID- 29472911 TI - A Novel Bifunctional Endolytic Alginate Lyase with Variable Alginate-Degrading Modes and Versatile Monosaccharide-Producing Properties. AB - Endo-type alginate lyases usually degrade alginate completely into various size defined unsaturated oligosaccharide products (>=disaccharides), while exoenzymes primarily produce monosaccharide products including saturated mannuronate (M) and guluronate (G) units and particularly unsaturated Delta units. Recently, two bifunctional alginate lyases have been identified as endolytic but M- and G producing with variable action modes. However, endolytic Delta-producing alginate lyases remain undiscovered. Herein, a new Flammeovirga protein, Aly2, was classified into the polysaccharide lyase 7 superfamily. The recombinant enzyme and its truncated protein showed similar stable biochemical characteristics. Using different sugar chains as testing substrates, we demonstrated that the two enzymes are bifunctional while G-preferring, endolytic whereas monosaccharide producing. Furthermore, the catalytic module of Aly2 can vary the action modes depending on the terminus type, molecular size, and M/G content of the substrate, thereby yielding different levels of M, G, and Delta units. Notably, the enzymes preferentially produce Delta units when digesting small size-defined oligosaccharide substrates, particularly the smallest substrate (unsaturated tetrasaccharide fractions). Deletion of the non-catalytic region of Aly2 caused weak changes in the action modes and biochemical characteristics. This study provided extended insights into alginate lyase groups with variable action modes for accurate enzyme use. PMID- 29472910 TI - Exploring the Genomic Traits of Non-toxigenic Vibrio parahaemolyticus Strains Isolated in Southern Chile. AB - Vibrio parahaemolyticus is the leading cause of seafood-borne gastroenteritis worldwide. As reported in other countries, after the rise and fall of the pandemic strain in Chile, other post-pandemic strains have been associated with clinical cases, including strains lacking the major toxins TDH and TRH. Since the presence or absence of tdh and trh genes has been used for diagnostic purposes and as a proxy of the virulence of V. parahaemolyticus isolates, the understanding of virulence in V. parahaemolyticus strains lacking toxins is essential to detect these strains present in water and marine products to avoid possible food-borne infection. In this study, we characterized the genome of four environmental and two clinical non-toxigenic strains (tdh-, trh-, and T3SS2-). Using whole-genome sequencing, phylogenetic, and comparative genome analysis, we identified the core and pan-genome of V. parahaemolyticus of strains of southern Chile. The phylogenetic tree based on the core genome showed low genetic diversity but the analysis of the pan-genome revealed that all strains harbored genomic islands carrying diverse virulence and fitness factors or prophage-like elements that encode toxins like Zot and RTX. Interestingly, the three strains carrying Zot-like toxin have a different sequence, although the alignment showed some conserved areas with the zot sequence found in V. cholerae. In addition, we identified an unexpected diversity in the genetic architecture of the T3SS1 gene cluster and the presence of the T3SS2 gene cluster in a non-pandemic environmental strain. Our study sheds light on the diversity of V. parahaemolyticus strains from the southern Pacific which increases our current knowledge regarding the global diversity of this organism. PMID- 29472912 TI - The Antimicrobial Activity of a Carbon Monoxide Releasing Molecule (EBOR-CORM-1) Is Shaped by Intraspecific Variation within Pseudomonas aeruginosa Populations. AB - Carbon monoxide releasing molecules (CORMs) have been suggested as a new synthetic class of antimicrobials to treat bacterial infections. Here we utilized a novel EBOR-CORM-1 ([NEt4][MnBr2(CO)4]) capable of water-triggered CO-release, and tested its efficacy against a collection of clinical Pseudomonas aeruginosa strains that differ in infection-related virulence traits. We found that while EBOR-CORM-1 was effective in clearing planktonic and biofilm cells of P. aeruginosa strain PAO1 in a concentration dependent manner, this effect was less clear and varied considerably between different P. aeruginosa cystic fibrosis (CF) lung isolates. While a reduction in cell growth was observed after 8 h of CORM application, either no effect or even a slight increase in cell densities and the amount of biofilm was observed after 24 h. This variation could be partly explained by differences in bacterial virulence traits: while CF isolates showed attenuated in vivo virulence and growth compared to strain PAO1, they formed much more biofilm, which could have potentially protected them from the CORM. Even though no clear therapeutic benefits against a subset of isolates was observed in an in vivo wax moth acute infection model, EBOR-CORM-1 was more efficient at reducing the growth of CF isolate co-culture populations harboring intraspecific variation, in comparison with efficacy against more uniform single isolate culture populations. Together these results suggest that CORMs could be effective at controlling genetically diverse P. aeruginosa populations typical for natural chronic CF infections and that the potential benefits of some antibiotics might not be observed if tested only against clonal bacterial populations. PMID- 29472913 TI - Benzyl-2-Acetamido-2-Deoxy-alpha-d-Galactopyranoside Increases Human Immunodeficiency Virus Replication and Viral Outgrowth Efficacy In Vitro. AB - Glycosylation of host and viral proteins is an important posttranslational modification needed to ensure correct function of glycoproteins. For this reason, we asked whether inhibition of O-glycosylation during human immunodeficiency virus (HIV) in vitro replication could affect HIV infectivity and replication rates. We used benzyl-2-acetamido-2-deoxy-alpha-d-galactopyranoside (BAGN), a compound that has been widely used to inhibit O-glycosylation in several cell lines. Pretreatment and culture of PHA-blast target cells with BAGN increased the percentage of HIV-infected cells (7.6-fold, p = 0.0115), the per-cell amount of HIV p24 protein (1.3-fold, p = 0.2475), and the viral particles in culture supernatants (7.1-fold, p = 0.0029) compared to BAGN-free cultures. Initiating infection with virus previously grown in the presence of BAGN further increased percentage of infected cells (30-fold, p < 0.0001), intracellular p24 (1.5-fold, p = 0.0433), and secreted viral particles (74-fold, p < 0.0001). BAGN-treated target cells showed less CD25 and CCR5 expression, but increased HLA-DR surface expression, which positively correlated with the number of infected cells. Importantly, BAGN improved viral outgrowth kinetics in 66% of the samples tested, including samples from HIV controllers and subjects in whom no virus could be expanded in the absence of BAGN. Sequencing of the isolated virus indicated no skewing of viral quasi-species populations when compared to BAGN-free culture conditions. BAGN also increased virus production in the ACH2 latency model when used together with latency-reversing agents. Taken together, our results identify BAGN treatment as a simple strategy to improve viral outgrowth in vitro and may provide novel insights into host restriction mechanisms and O-glycosylation related therapeutic targets for HIV control strategies. PMID- 29472915 TI - Endothelial Cell Focal Adhesion Regulates Transendothelial Migration and Subendothelial Crawling of T Cells. AB - Leukocytes circulating in the blood stream leave out of blood vessels and infiltrate into inflamed tissues to perform immune responses. Endothelial cells (ECs) lining interior of the post-capillary venules regulate various steps of leukocyte extravasation. In response to inflammatory signals, ECs upregulate adhesion molecules and produce/present chemokines to support firm adhesion and intraluminal crawling of leukocytes. They also remodel junctions to facilitate leukocyte transendothelial migration (TEM). While roles of apical/lateral components of EC layers in regulating leukocyte extravasation have been extensively investigated, relatively little attention has been paid to the basal part of EC layers comprising subendothelial spaces. In this study, we employed interference reflection microscopy (IRM), a microscopy technique specialized for label-free visualization of cell-substrate contact, to study detailed dynamic interactions between basal part of ECs and T cells underneath EC monolayer. For TEM, T cells on EC monolayer extended protrusions through junctions to explore subendothelial spaces, and EC focal adhesions (EC-FAs) acted as physical barrier for the protrusion. Therefore, preferential TEM occurred through junctions where near-junction focal adhesion (NJ-FA) density of ECs was low. After TEM, T cells performed subendothelial crawling (SEC) with flattened morphology and reduced migration velocity due to tight confinement. T cell SEC mostly occurred through gaps formed in between EC-FAs with minimally breaking EC-FAs. Tumor necrosis factor-alpha (TNF-alpha) treatment significantly loosened confinement in subendothelial spaces and reduced NJ-FA density of ECs, thus remodeled basal part of EC layer to facilitate leukocyte extravasation. PMID- 29472914 TI - Monocyte-Derived Signals Activate Human Natural Killer Cells in Response to Leishmania Parasites. AB - Activated natural killer (NK) cells release interferon (IFN)-gamma, which is crucial for the control of intracellular pathogens such as Leishmania. In contrast to experimental murine leishmaniasis, the human NK cell response to Leishmania is still poorly characterized. Here, we investigated the interaction of human blood NK cells with promastigotes of different Leishmania species (Leishmania major, Leishmania mexicana, Leishmania infantum, and Leishmania donovani). When peripheral blood mononuclear cells or purified NK cells and monocytes (all derived from healthy blood donors from Germany without a history of leishmaniasis) were exposed to promastigotes, NK cells showed increased surface expression of the activation marker CD69. The extent of this effect varied depending on the Leishmania species; differences between dermotropic and viscerotropic L. infantum strains were not observed. Upregulation of CD69 required direct contact between monocytes and Leishmania and was partly inhibitable by anti-interleukin (IL)-18. Unexpectedly, IL-18 was undetectable in most of the supernatants (SNs) of monocyte/parasite cocultures. Confocal fluorescence microscopy of non-permeabilized cells revealed that Leishmania infected monocytes trans-presented IL-18 to NK cells. Native, but not heat treated SNs of monocyte/Leishmania cocultures also induced CD69 on NK cells, indicating the involvement of a soluble heat-labile factor other than IL-18. A role for the NK cell-activating cytokines IL-1beta, IL-2, IL-12, IL-15, IL-21, and IFN-alpha/beta was excluded. The increase of CD69 was not paralleled by NK cell IFN-gamma production or enhanced cytotoxicity. However, prior exposure of NK cells to Leishmania parasites synergistically increased their IFN-gamma release in response to IL-12, which was dependent on endogenous IL-18. CD1c+ dendritic cells were identified as possible source of Leishmania-induced IL-12. Finally, we observed that direct contact between Leishmania and NK cells reduced the expression of CD56 mRNA and protein on NK cells. We conclude that Leishmania activate NK cells via trans-presentation of IL-18 by monocytes and by a monocyte derived soluble factor. IL-12 is needed to elicit the IFN-gamma-response of NK cells, which is likely to be an important component of the innate control of the parasite. PMID- 29472916 TI - Fortunellin-Induced Modulation of Phosphatase and Tensin Homolog by MicroRNA-374a Decreases Inflammation and Maintains Intestinal Barrier Function in Colitis. AB - Activation of phosphatase and tensin homolog (PTEN) is known to induce cell apoptosis. MicroRNA-374a (miR-374a), which can suppress PTEN expression, has been found abnormally expressed in inflammatory bowel disease (IBD). Fortunellin is a citrus flavonoid that is a potential anti-inflammation agent in inflammatory diseases. The present study investigated the effects and mechanisms underlying fortunellin-induced inhibition of PTEN in IBD. Colitis was established in rats by the intracolonic administration of 2,4,6-trinitrobenzene sulfonic acid to mimic human ulcerative colitis, which is the main type of IBD. miR-374a expression was measured by quantitative real-time polymerase chain reaction, and the regulation of PTEN by miR-374a was evaluated by dual luciferase reporter assay. Western blotting was used to measure the corresponding protein expression. Fortunellin ameliorated colitis symptoms, including excessive inflammation and oxidative stress. Fortunellin decreased epithelial cell apoptosis through inhibiting PTEN expression in colitis. Fortunellin-induced downregulation of PTEN could be counteracted by miR-374a depletion. Moreover, knockdown of miR-374a in vivo partly inhibited the effects of fortunellin on rat colitis. In conclusion, PTEN inhibition contributes to the amelioration effects of fortunellin on colitis. It was confirmed that fortunellin targets miR-374a, which is a negative regulator of PTEN. This study provides novel insights into the pathological mechanisms and treatment alternatives of colitis. PMID- 29472917 TI - Senescent T-Cells Promote Bone Loss in Rheumatoid Arthritis. AB - Objective: T-cells are critical players in the pathogenesis of osteoporosis in patients with rheumatoid arthritis (RA). Premature senescence of lymphocytes including the accumulation of senescent CD4+ T-cells is a hallmark feature of RA. Whether T-cell senescence is associated with bone loss in RA patients is elusive so far. Methods: This includes a prospective study of consecutive patients with RA (n = 107), patients with primary osteopenia/-porosis (n = 75), and healthy individuals (n = 38). Bone mineral density (BMD) was determined by dual-energy X ray absorptiometry scan. Flow cytometry, magnetic-associated cell sorting, and cell culture experiments were performed to analyze the pro-osteoclastic phenotype and the function of senescent CD4+CD28- T-cells. Results: Patients with osteopenia/-porosis yielded a higher prevalence of senescent CD4+CD28- T-cells than individuals with normal BMD, in the RA, as well as in the non-RA cohort. Receptor activator of nuclear factor kappa-B ligand (RANKL) was expressed at higher levels on CD4+CD28- T-cells as compared to CD28+ T-cells. Stimulation with interleukin-15 led to an up-regulation of RANKL expression, particularly on CD28- T-cells. CD4+CD28- T-cells induced osteoclastogenesis more efficiently than CD28+ T-cells. Conclusion: Our data indicate that senescent T-cells promote osteoclastogenesis more efficiently than conventional CD28+ T-cells, which might contribute to the pathogenesis of systemic bone loss in RA and primary osteoporosis.

Using methods such as phage, ribosome, and yeast display, high affinity binders can be selected from diverse repertoires. Here, we review strategies for the next-generation sequencing (NGS) of phage- and other antibody display libraries, as well as NGS platforms and analysis tools. Moreover, we discuss recent examples relating to the use of NGS to assess library diversity, clonal enrichment, and affinity maturation. PMID- 29472919 TI - In the Absence of Central pre-B Cell Receptor Selection, Peripheral Selection Attempts to Optimize the Antibody Repertoire by Enriching for CDR-H3 Y101. AB - Sequential developmental checkpoints are used to "optimize" the B cell antigen receptor repertoire by minimizing production of autoreactive or useless immunoglobulins and enriching for potentially protective antibodies. The first and apparently most impactful checkpoint requires MUHC to form a functional pre-B cell receptor (preBCR) by associating with surrogate light chain, which is composed of VpreB and lambda5. Absence of any of the preBCR components causes a block in B cell development that is characterized by severe immature B cell lymphopenia. Previously, we showed that preBCR controls the amino acid content of the third complementary determining region of the H chain (CDR-H3) by using a VpreB amino acid motif (RDR) to select for tyrosine at CDR-H3 position 101 (Y101). In antibodies bound to antigen, Y101 is commonly in direct contact with the antigen, thus preBCR selection impacts the antigen binding characteristics of the repertoire. In this work, we sought to determine the forces that shape the peripheral B cell repertoire when it is denied preBCR selection. Using bromodeoxyuridine incorporation and evaluation of apoptosis, we found that in the absence of preBCR there is increased turnover of B cells due to increased apoptosis. CDR-H3 sequencing revealed that this is accompanied by adjustments to DH identity, DH reading frame, JH, and CDR-H3 amino acid content. These adjustments in the periphery led to wild-type levels of CDR-H3 Y101 content among transitional (T1), mature recirculating, and marginal zone B cells. However, peripheral selection proved incomplete, with failure to restore Y101 levels in follicular B cells and increased production of dsDNA-binding IgM antibodies. PMID- 29472921 TI - Kinetics of HIV-Specific CTL Responses Plays a Minimal Role in Determining HIV Escape Dynamics. AB - Cytotoxic T lymphocytes (CTLs) have been suggested to play an important role in controlling human immunodeficiency virus (HIV-1 or simply HIV) infection. HIV, due to its high mutation rate, can evade recognition of T cell responses by generating escape variants that cannot be recognized by HIV-specific CTLs. Although HIV escape from CTL responses has been well documented, factors contributing to the timing and the rate of viral escape from T cells have not been fully elucidated. Fitness costs associated with escape and magnitude of the epitope-specific T cell response are generally considered to be the key in determining timing of HIV escape. Several previous analyses generally ignored the kinetics of T cell responses in predicting viral escape by either considering constant or maximal T cell response; several studies also considered escape from different T cell responses to be independent. Here, we focus our analysis on data from two patients from a recent study with relatively frequent measurements of both virus sequences and HIV-specific T cell response to determine impact of CTL kinetics on viral escape. In contrast with our expectation, we found that including temporal dynamics of epitope-specific T cell response did not improve the quality of fit of different models to escape data. We also found that for well-sampled escape data, the estimates of the model parameters including T cell killing efficacy did not strongly depend on the underlying model for escapes: models assuming independent, sequential, or concurrent escapes from multiple CTL responses gave similar estimates for CTL killing efficacy. Interestingly, the model assuming sequential escapes (i.e., escapes occurring along a defined pathway) was unable to accurately describe data on escapes occurring rapidly within a short-time window, suggesting that some of model assumptions must be violated for such escapes. Our results thus suggest that the current sparse measurements of temporal CTL dynamics in blood bear little quantitative information to improve predictions of HIV escape kinetics. More frequent measurements using more sensitive techniques and sampling in secondary lymphoid tissues may allow to better understand whether and how CTL kinetics impacts viral escape. PMID- 29472922 TI - Efficacy of T Regulatory Cells, Th17 Cells and the Associated Markers in Monitoring Tuberculosis Treatment Response. AB - Treatment monitoring is an essential aspect for tuberculosis (TB) disease management. Sputum smear microscopy is the only available tool for monitoring, but it suffers from demerits. Therefore, we sought to evaluate markers and cellular subsets of T regulatory (Treg) cells and T helper (Th) 17 cells in pulmonary TB patients (PTB) for TB treatment monitoring. Peripheral blood mononuclear cells (PBMCs) were stimulated in vitro (with purified protein derivative (PPD)) overnight which was followed by a polychromatic flow cytometry approach to study Treg and Th17 markers and cellular subsets in PTB (n = 12) undergoing antituberculous treatment (ATT). The baseline levels of these markers and cellular subsets were evaluated in normal healthy subjects (NHS). We observed a significant decrease in the expression of CD25 (p<0.01) marker and percentage of T-cell subsets like CD4+CD25+ (p<0.001) and CD4+CD25+CD39+ (p<0.05) at the end of intensive phase (IP) as well as in the continuation phase (CP) of ATT. A decrease in CD25 marker expression and percentage of CD4+CD25+ T cell subset showed a positive correlation to sputum conversion both in high and low sputum positive PTB. In eight PTB with cavitary lesions, only CD4+CD25+FoxP3 Treg subset manifested a significant decrease at the end of CP. Thus, results of this study show that CD25 marker and CD4+CD25+ T cells can serve as better markers for monitoring TB treatment efficacy. The Treg subset CD4+CD25+FoxP3 may be useful for prediction of favorable response in PTB with extensive lung lesions. However, these findings have to be evaluated in a larger patient cohort. PMID- 29472920 TI - Host Lipid Mediators in Leprosy: The Hypothesized Contributions to Pathogenesis. AB - The spectrum of clinical forms observed in leprosy and its pathogenesis are dictated by the host's immune response against Mycobacterium leprae, the etiological agent of leprosy. Previous results, based on metabolomics studies, demonstrated a strong relationship between clinical manifestations of leprosy and alterations in the metabolism of omega3 and omega6 polyunsaturated fatty acids (PUFAs), and the diverse set of lipid mediators derived from PUFAs. PUFA-derived lipid mediators provide multiple functions during acute inflammation, and some lipid mediators are able to induce both pro- and anti-inflammatory responses as determined by the cell surface receptors being expressed, as well as the cell type expressing the receptors. However, little is known about how these compounds influence cellular immune activities during chronic granulomatous infectious diseases, such as leprosy. Current evidence suggests that specialized pro resolving lipid mediators (SPMs) are involved in the down-modulation of the innate and adaptive immune response against M. leprae and that alteration in the homeostasis of pro-inflammatory lipid mediators versus SPMs is associated with dramatic shifts in the pathogenesis of leprosy. In this review, we discuss the possible consequences and present new hypotheses for the involvement of omega3 and omega6 PUFA metabolism in the pathogenesis of leprosy. A specific emphasis is placed on developing models of lipid mediator interactions with the innate and adaptive immune responses and the influence of these interactions on the outcome of leprosy. PMID- 29472923 TI - A Prominent Role of Interleukin-18 in Acetaminophen-Induced Liver Injury Advocates Its Blockage for Therapy of Hepatic Necroinflammation. AB - Acetaminophen [paracetamol, N-acetyl-p-aminophenol (APAP)]-induced acute liver injury (ALI) not only remains a persistent clinical challenge but likewise stands out as well-characterized paradigmatic model of drug-induced liver damage. APAP intoxication associates with robust hepatic necroinflammation the role of which remains elusive with pathogenic but also pro-regenerative/-resolving functions being ascribed to leukocyte activation. Here, we shine a light on and put forward a unique role of the interleukin (IL)-1 family member IL-18 in experimental APAP induced ALI. Indeed, amelioration of disease as previously observed in IL-18 deficient mice was further substantiated herein by application of the IL-18 opponent IL-18-binding protein (IL-18BPd:Fc) to wild-type mice. Data altogether emphasize crucial pathological action of this cytokine in APAP toxicity. Adding recombinant IL-22 to IL-18BPd:Fc further enhanced protection from liver injury. In contrast to IL-18, the role of prototypic pro-inflammatory IL-1 and tumor necrosis factor-alpha is controversially discussed with lack of effects or even protective action being repeatedly reported. A prominent detrimental function for IL-18 in APAP-induced ALI as proposed herein should relate to its pivotal role for hepatic expression of interferon-gamma and Fas ligand, both of which aggravate APAP toxicity. As IL-18 serum levels increase in patients after APAP overdosing, targeting IL-18 may evolve as novel therapeutic option in those hard to-treat patients where standard therapy with N-acetylcysteine is unsuccessful. Being a paradigmatic experimental model of ALI, current knowledge on ill-fated properties of IL-18 in APAP intoxication likewise emphasizes the potential of this cytokine to serve as therapeutic target in other entities of inflammatory liver diseases. PMID- 29472924 TI - Signal Transducer and Activator of Transcription 3 Control of Human T and B Cell Responses. AB - Signal transducer and activator of transcription 3 (STAT3) is a transcription factor that is activated downstream of many key cytokine receptors expressed by lymphocytes. As such, it plays a critical role in regulating B cells as well as CD4+ and CD8+ T cells. Patients with clinically significant immunodeficiency and immune dysregulation resulting from loss-of-function or gain-of-function mutations in STAT3 have been described. These individuals provide insight into the critical role of this transcription factor in the regulation of immune responses and the balance between effective immune protection and autoimmunity. PMID- 29472926 TI - Eliminating Factor H-Binding Activity of Borrelia burgdorferi CspZ Combined with Virus-Like Particle Conjugation Enhances Its Efficacy as a Lyme Disease Vaccine. AB - The spirochete Borrelia burgdorferi is the causative agent of Lyme disease, the most common tick-borne disease in the US and Europe. No potent human vaccine is currently available. The innate immune complement system is vital to host defense against pathogens, as complement activation on the surface of spirochetes results in bacterial killing. Complement system is inhibited by the complement regulator factor H (FH). To escape killing, B. burgdorferi produces an outer surface protein CspZ that binds FH to inhibit complement activation on the cell surface. Immunization with CspZ alone does not protect mice from infection, which we speculate is because FH-binding cloaks potentially protective epitopes. We modified CspZ by conjugating to virus-like particles (VLP-CspZ) and eliminating FH binding (modified VLP-CspZ) to increase immunogenicity. We observed greater bactericidal antibody titers in mice vaccinated with modified VLP-CspZ: A serum dilution of 1:395 (modified VLP-CspZ) vs 1:143 (VLP-CspZ) yielded 50% borreliacidal activity. Immunizing mice with modified VLP-CspZ cleared spirochete infection, as did passive transfer of elicited antibodies. This work developed a novel Lyme disease vaccine candidate by conjugating CspZ to VLP and eliminating FH-binding ability. Such a strategy of conjugating an antigen to a VLP and eliminating binding to the target ligand can serve as a general model for developing vaccines against other bacterial infectious agents. PMID- 29472925 TI - Understanding the Unfolded Protein Response in the Pathogenesis of Asthma. AB - Asthma is a heterogeneous, chronic inflammatory disease of the airways. It is a complex disease with different clinical phenotypes and results in a substantial socioeconomic burden globally. Poor understanding of pathogenic mechanisms of the disease hinders the investigation into novel therapeutics. Emerging evidence of the unfolded protein response (UPR) in the endoplasmic reticulum (ER) has demonstrated previously unknown functions of this response in asthma development. A worsening of asthmatic condition can be brought on by stimuli such as oxidative stress, pathogenic infections, and allergen exposure. All of which can induce ER stress and activate UPR leading to activation of different inflammatory responses and dysregulate the innate immune functions in the airways. The UPR as a central regulator of asthma pathogenesis may explain several unknown mechanism of the disease onset, which leads us in new directions for future asthma treatments. In this review, we summarize and discuss the causes and impact of ER-UPR in driving the pathogenesis of asthma and highlight its importance in clinical implications. PMID- 29472927 TI - Genome-Wide Identification of Destruxin A-Responsive Immunity-Related MicroRNAs in Diamondback Moth, Plutella xylostella. AB - Plutella xylostella, a global key pest, is one of the major lepidopteran pests of cruciferous vegetables owing to its strong ability of resistance development to a wide range of insecticides. Destruxin A, a mycotoxin of the entomopathogenic fungus, Metarhizium anisopliae, has broad-spectrum insecticidal effects and has been used as an alternative control strategy to reduce harmful effects of insecticides. However, microRNA (miRNA)-regulated reactions against destruxin A have not been elucidated yet. Therefore, here, to identify immunity-related miRNAs, we constructed four small RNA libraries from destruxin A-injected larvae of P. xylostella at three different time courses (2, 4, and 6 h) with a control, and sequenced by Illumina. Our results showed that totally 187 known and 44 novel miRNAs were identified in four libraries by bioinformatic analysis. Interestingly, among differentially expressed known miRNAs, some conserved miRNAs, such as miR-263, miR-279, miR-306, miR-2a, and miR-308, predicted to be involved in regulating immunity-related genes, were also identified. Worthy to mention, miR-306 and miR-279 were also listed as common abundantly expressed miRNA in all treatments. The Kyoto Encyclopedia of Genes and Genomes pathway analysis also indicated that differentially expressed miRNAs were involved in several immunity-related signaling pathways, including toll signaling pathway, IMD signaling pathway, JAK-STAT signaling pathway, and cell adhesion molecules signaling pathway. To the best of our knowledge, this is the first comprehensive report of destruxin A-responsive immunity-related miRNAs in P. xylostella. Our findings will improve in understanding the role of destruxin A-responsive miRNAs in the host immune system and would be useful to develop biological control strategies for controlling P. xylostella. PMID- 29472929 TI - Infectious Sporozoites of Plasmodium berghei Effectively Activate Liver CD8alpha+ Dendritic Cells. AB - Immunization with radiation-attenuated sporozoites (RAS) shown to confer complete sterile protection against Plasmodia liver-stage (LS) infection that lasts about 6 to 9 months in mice. We have found that the intermittent infectious sporozoite challenge to immune mice following RAS vaccination extends the longevity of sterile protection by maintaining CD8+ T cell memory responses to LS infection. It is reported that CD8alpha+ dendritic cells (DCs) are involved in the induction of LS-specific CD8+ T cells following RAS or genetically attenuated parasite (GAP) vaccination. In this study, we demonstrate that CD8alpha+ DCs respond differently to infectious sporozoite or RAS inoculation. The higher accumulation and activation of CD8alpha+ DCs was seen in the liver in response to infectious sporozoite 72 h postinoculation and found to be associated with higher expression of chemokines (CCL-20 and CCL-21) and type I interferon response via toll-like receptor signaling in liver. Moreover, the infectious sporozoites were found to induce qualitative changes in terms of the increased MHCII expression as well as costimulatory molecules including CD40 on the CD8alpha+ DCs compared to RAS inoculation. We have also found that infectious sporozoite challenge increased CD40L-expressing CD4+ T cells, which could help CD8+ T cells in the liver through "licensing" of the antigen-presenting cells. Our results suggest that infectious sporozoite challenge to prior RAS immunized mice modulates the CD8alpha+ DCs, which might be shaping the fate of memory CD8+ T cells against Plasmodium LS infection. PMID- 29472928 TI - Immunothrombotic Activity of Damage-Associated Molecular Patterns and Extracellular Vesicles in Secondary Organ Failure Induced by Trauma and Sterile Insults. AB - Despite significant improvements in injury prevention and emergency response, injury-related death and morbidity continues to increase in the US and worldwide. Patients with trauma, invasive operations, anti-cancer treatment, and organ transplantation produce a host of danger signals and high levels of pro inflammatory and pro-thrombotic mediators, such as damage-associated molecular patterns (DAMPs) and extracellular vesicles (EVs). DAMPs (e.g., nucleic acids, histone, high-mobility group box 1 protein, and S100) are molecules released from injured, stressed, or activated cells that act as endogenous ligands of innate immune receptors, whereas EVs (e.g., microparticle and exosome) are membranous vesicles budding off from plasma membranes and act as messengers between cells. DAMPs and EVs can stimulate multiple innate immune signaling pathways and coagulation cascades, and uncontrolled DAMP and EV production causes systemic inflammatory and thrombotic complications and secondary organ failure (SOF). Thus, DAMPs and EVs represent potential therapeutic targets and diagnostic biomarkers for SOF. High plasma levels of DAMPs and EVs have been positively correlated with mortality and morbidity of patients or animals with trauma or surgical insults. Blocking or neutralizing DAMPs using antibodies or small molecules has been demonstrated to ameliorate sepsis and SOF in animal models. Furthermore, a membrane immobilized with nucleic acid-binding polymers captured and removed multiple DAMPs and EVs from extracellular fluids, thereby preventing the onset of DAMP- and EV-induced inflammatory and thrombotic complications in vitro and in vivo. In this review, we will summarize the current state of knowledge of DAMPs, EVs, and SOF and discuss potential therapeutics and preventive intervention for organ failure secondary to trauma, surgery, anti cancer therapy, and allogeneic transplantation. PMID- 29472930 TI - Impaired Control of Epstein-Barr Virus Infection in B-Cell Expansion with NF kappaB and T-Cell Anergy Disease. AB - B-cell expansion with NF-kappaB and T-cell anergy (BENTA) disease is a B-cell specific lymphoproliferative disorder caused by germline gain-of-function mutations in CARD11. These mutations force the CARD11 scaffold into an open conformation capable of stimulating constitutive NF-kappaB activation in lymphocytes, without requiring antigen receptor engagement. Many BENTA patients also suffer from recurrent infections, with 7 out of 16 patients exhibiting chronic, low-grade Epstein-Barr virus (EBV) viremia. In this mini-review, we discuss EBV infection in the pathogenesis and clinical management of BENTA disease, and speculate on mechanisms that could explain inadequate control of viral infection in BENTA patients. PMID- 29472931 TI - Dendritic Cell Migration to Skin-Draining Lymph Nodes Is Controlled by Dermatan Sulfate and Determines Adaptive Immunity Magnitude. AB - For full activation of naive adaptive lymphocytes in skin-draining lymph nodes (LNs), presentation of peptide:MHC complexes by LN-resident and skin-derived dendritic cells (DCs) that encountered antigens (Ags) is an absolute prerequisite. To get to the nearest draining LN upon intradermal immunization, DCs need to migrate from the infection site to the afferent lymphatics, which can only be reached by traversing a collagen-dense network located in the dermis of the skin through the activity of proteolytic enzymes. Here, we show that mice with altered collagen fibrillogenesis resulting in thicker collagen fibers in the skin display a reduced DC migration to the draining LN upon immune challenge. Consequently, the initiation of the cellular and humoral immune response was diminished. Ag-specific CD8+ and CD4+ T cells as well as Ag-specific germinal center B cells and serum immunoglobulin levels were significantly decreased. Hence, we postulate that alterations to the production of extracellular matrix, as seen in various connective tissue disorders, may in the end affect the qualitative outcome of adaptive immunity. PMID- 29472932 TI - In Vitro-Generated Tc17 Cells Present a Memory Phenotype and Serve As a Reservoir of Tc1 Cells In Vivo. AB - Memory CD8+ T cells are ideal candidates for cancer immunotherapy because they can mediate long-term protection against tumors. However, the therapeutic potential of different in vitro-generated CD8+ T cell effector subsets to persist and become memory cells has not been fully characterized. Type 1 CD8+ T (Tc1) cells produce interferon-gamma and are endowed with high cytotoxic capacity, whereas IL-17-producing CD8+ T (Tc17) cells are less cytotoxic but display enhanced self-renewal capacity. We sought to evaluate the functional properties of in vitro-generated Tc17 cells and elucidate their potential to become long lasting memory cells. Our results show that in vitro-generated Tc17 cells display a greater in vivo persistence and expansion in response to secondary antigen stimulation compared to Tc1 cells. When transferred into recipient mice, Tc17 cells persist in secondary lymphoid organs, present a recirculation behavior consistent with central memory T cells, and can shift to a Tc1 phenotype. Accordingly, Tc17 cells are endowed with a higher mitochondrial spare respiratory capacity than Tc1 cells and express higher levels of memory-related molecules than Tc1 cells. Together, these results demonstrate that in vitro-generated Tc17 cells acquire a central memory program and provide a lasting reservoir of Tc1 cells in vivo, thus supporting the use of Tc17 lymphocytes in the design of novel and more effective therapies. PMID- 29472933 TI - Leucine-Rich Repeat Kinase 2 Controls the Ca2+/Nuclear Factor of Activated T Cells/IL-2 Pathway during Aspergillus Non-Canonical Autophagy in Dendritic Cells. AB - The Parkinson's disease-associated protein, Leucine-rich repeat kinase 2 (LRRK2), a known negative regulator of nuclear factor of activated T cells (NFAT), is expressed in myeloid cells such as macrophages and dendritic cells (DCs) and is involved in the host immune response against pathogens. Since, the Ca2+/NFAT/IL-2 axis has been previously found to regulate DC response to the fungus Aspergillus, we have investigated the role played by the kinase LRRK2 during fungal infection. Mechanistically, we found that in the early stages of the non-canonical autophagic response of DCs to the germinated spores of Aspergillus, LRRK2 undergoes progressive degradation and regulates NFAT translocation from the cytoplasm to the nucleus. Our results shed new light on the complexity of the Ca2+/NFAT/IL-2 pathway, where LRRK2 plays a role in controlling the immune response of DCs to Aspergillus. PMID- 29472934 TI - Alleviation of Nitrogen and Sulfur Deficiency and Enhancement of Photosynthesis in Arabidopsis thaliana by Overexpression of Uroporphyrinogen III Methyltransferase (UPM1). AB - Siroheme, an iron-containing tetrapyrrole, is the prosthetic group of nitrite reductase (NiR) and sulfite reductase (SiR); it is synthesized from uroporphyrinogen III, an intermediate of chlorophyll biosynthesis, and is required for nitrogen (N) and sulfur (S) assimilation. Further, uroporphyrinogen III methyltransferase (UPM1), responsible for two methylation reactions to form dihydrosirohydrochlorin, diverts uroporphyrinogen III from the chlorophyll biosynthesis pathway toward siroheme synthesis. AtUPM1 [At5g40850] was used to produce both sense and antisense plants of Arabidopsis thaliana in order to modulate siroheme biosynthesis. In our experiments, overexpression of AtUPM1 signaled higher NiR (NII) and SiR gene and gene product expression. Increased NII expression was found to regulate and enhance the transcript and protein abundance of nitrate reductase (NR). We suggest that elevated NiR, NR, and SiR expression must have contributed to the increased synthesis of S containing amino acids in AtUPM1overexpressors, observed in our studies. We note that due to higher N and S assimilation in these plants, total protein content had increased in these plants. Consequently, chlorophyll biosynthesis increased in these sense plants. Higher chlorophyll and protein content of plants upregulated photosynthetic electron transport and carbon assimilation in the sense plants. Further, we have observed increased plant biomass in these plants, and this must have been due to increased N, S, and C assimilation. On the other hand, in the antisense plants, the transcript abundance, and protein content of NiR, and SiR was shown to decrease, resulting in reduced total protein and chlorophyll content. This led to a decrease in photosynthetic electron transport rate, carbon assimilation and plant biomass in these antisense plants. Under nitrogen or sulfur starvation conditions, the overexpressors had higher protein content and photosynthetic electron transport rate than the wild type (WT). Conversely, the antisense plants had lower protein content and photosynthetic efficiency in N-deficient environment. Our results clearly demonstrate that upregulation of siroheme biosynthesis leads to increased nitrogen and sulfur assimilation, and this imparts tolerance to nitrogen and sulfur deficiency in Arabidopsis thaliana plants. PMID- 29472936 TI - Durum Wheat Landraces from East and West Regions of the Mediterranean Basin Are Genetically Distinct for Yield Components and Phenology. AB - Genetic diversity of durum wheat landraces is a powerful tool for the introgression of new alleles of commercial interest in breeding programs. In a previous study, our team structured a collection of 172 durum wheat landraces from 21 Mediterranean countries in four genetic populations related to their geographical origin: east Mediterranean (17), east Balkan and Turkey (23), west Balkan and Egypt (25), and West Mediterranean (73), leaving 34 genotypes as admixed, and association mapping was carried out for important agronomic traits. Using a subset of this collection, the current study identified 23 marker alleles with a differential frequency in landraces from east and west regions of the Mediterranean Basin, which affected important agronomic traits. Eastern landraces had higher frequencies than the western ones of alleles increasing the number of spikes (wPt-5385 on chromosome 1B), grains per m2 (wPt-0841 on chromosome 7B), and grain filling duration (7 significant marker trait associations). Eastern landraces had higher frequencies of marker alleles located on chromosomes 4A, 5B, and 6B associated with reduced cycle length, and lighter grains than the western ones. Also for lower kernel weight, four marker alleles were located on chromosome 1A. Breeders may use the molecular markers identified in the current study for improving yield under specific Mediterranean environments.

Advances in video imaging of chlorophyll fluorescence have now made it possible to study photosynthesis at all levels from individual cells to entire crop populations. Since the technology delivers quantitative data, is easily scaled up and can be readily combined with other approaches, it has become a powerful phenotyping tool for the identification of factors relevant to photosynthesis. Here, we review genetic chlorophyll fluorescence-based screens of libraries of Arabidopsis and Chlamydomonas mutants, discuss its application to high-throughput phenotyping in quantitative genetics and highlight potential future developments. PMID- 29472937 TI - Quantitative Trait Transcripts Mapping Coupled with Expression Quantitative Trait Loci Mapping Reveal the Molecular Network Regulating the Apetalous Characteristic in Brassica napus L. AB - The apetalous trait of rapeseed (Brassica napus, AACC, 2n = 38) is important for breeding an ideal high-yield rapeseed with superior klendusity to Sclerotinia sclerotiorum. Currently, the molecular mechanism underlying the apetalous trait of rapeseed is unclear. In this study, 14 petal regulators genes were chosen as target genes (TGs), and the expression patterns of the 14 TGs in the AH population, containing 189 recombinant inbred lines derived from a cross between apetalous "APL01" and normal "Holly," were analyzed in two environments using qRT PCR. Phenotypic data of petalous degree (PDgr) in the AH population were obtained from the two environments. Both quantitative trait transcript (QTT)-association mapping and expression QTL (eQTL) analyses of TGs expression levels were performed to reveal regulatory relationships among TGs and PDgr. QTT mapping for PDgr determined that PLURIPETALA (PLP) was the major negative QTT associated with PDgr in both environments, suggesting that PLP negatively regulates the petal development of line "APL01." The QTT mapping of PLP expression levels showed that CHROMATIN-REMODELING PROTEIN 11 (CHR11) was positively associated with PLP expression, indicating that CHR11 acts as a positive regulator of PLP expression. Similarly, QTT mapping for the remaining TGs identified 38 QTTs, associated with 13 TGs, and 31 QTTs, associated with 10 TGs, respectively, in the first and second environments. Additionally, eQTL analyses of TG expression levels showed that 12 and 11 unconditional eQTLs were detected in the first and second environment, respectively. Based on the QTTs and unconditional eQTLs detected, we presented a hypothetical molecular regulatory network in which 14 petal regulators potentially regulated the apetalous trait in "APL01" through the CHR11 PLP pathway. PLP acts directly as the terminal signal integrator negatively regulating petal development in the CHR11-PLP pathway. These findings will aid in the understanding the molecular mechanism underlying the apetalous trait of rapeseed.

AB - The dinitroaniline herbicides (particularly trifluralin) have been globally used in many crops for selective grass weed control. Consequently, trifluralin resistance has been documented in several important crop weed species and has recently reached a level of concern in Australian Lolium rigidum populations. Here, we report novel mutations in the L. rigidum alpha-tubulin gene which confer resistance to trifluralin and other dinitroaniline herbicides. Nucleotide mutations at the highly conserved codon Arg-243 resulted in amino acid substitutions of Met or Lys. Rice calli transformed with the mutant 243-Met or 243-Lys alpha-tubulin genes were 4- to 8-fold more resistant to trifluralin and other dinitroaniline herbicides (e.g., ethalfluralin and pendimethalin) compared to calli transformed with the wild type alpha-tubulin gene from L. rigidum. Comprehensive modeling of molecular docking predicts that Arg-243 is close to the trifluralin binding site on the alpha-tubulin surface and that replacement of Arg 243 by Met/Lys-243 results in a spatial shift of the trifluralin binding domain, reduction of trifluralin-tubulin contacts, and unfavorable interactions. The major effect of these substitutions is a significant rise of free interaction energy between alpha-tubulin and trifluralin, as well as between trifluralin and its whole molecular environment. These results demonstrate that the Arg-243 residue in alpha-tubulin is a determinant for trifluralin sensitivity, and the novel Arg-243-Met/Lys mutations may confer trifluralin resistance in L. rigidum. PMID- 29472939 TI - Dominant Species in Subtropical Forests Could Decrease Photosynthetic N Allocation to Carboxylation and Bioenergetics and Enhance Leaf Construction Costs during Forest Succession. AB - It is important to understand how eco-physiological characteristics shift in forests when elucidating the mechanisms underlying species replacement and the process of succession and stabilization. In this study, the dominant species at three typical successional stages (early-, mid-, and late-succession) in the subtropical forests of China were selected. At each stage, we compared the leaf construction costs (CC), payback time (PBT), leaf area based N content (NA), maximum CO2 assimilation rate (Pmax), specific leaf area (SLA), photosynthetic nitrogen use efficiency (PNUE), and leaf N allocated to carboxylation (NC), and to bioenergetics (NB). The relationships between these leaf functional traits were also determined. The results showed that the early-succession forest is characterized with significantly lower leaf CC, PBT, NA, but higher Pmax, SLA, PNUE, NC, and NB, in relation to the late-succession forest. From the early- to the late-succession forests, the relationship between Pmax and leaf CC strengthened, whereas the relationships between NB, NC, PNUE, and leaf CC weakened. Thus, the dominant species are able to decrease the allocation of the photosynthetic N fraction to carboxylation and bioenergetics during forest succession. The shift in these leaf functional traits and their linkages might represent a fundamental physiological mechanism that occurs during forest succession and stabilization. PMID- 29472940 TI - Inheritance and Linkage of Virulence Genes in Chinese Predominant Race CYR32 of the Wheat Stripe Rust Pathogen Puccinia striiformis f. sp. tritici. AB - Puccinia striiformis f.sp. tritici (Pst) is the causal agent of stripe (yellow) rust on wheat. It seriously threatens wheat production worldwide. The obligate biotrophic fungus is highly capable of producing new virulent races that can overcome resistance. Studying the inheritance of Pst virulence using the classical genetic approach was not possible until the recent discovery of its sexual stage on barberry plants. In the present study, 127 progeny isolates were obtained by selfing a representative Chinese Yellow Rust (CYR) race, CYR32, on Berberis aggregate. The parental isolate and progeny isolates were characterized by testing them on 25 wheat lines with different Yr genes for resistance and 10 simple sequence repeat (SSR) markers. The 127 progeny isolates were classified into 27 virulence phenotypes (VPs), and 65 multi-locus genotypes (MLGs). All progeny isolates and the parental isolate were avirulent to Yr5, Yr8, Yr10, Yr15, Yr24, Yr26, Yr32, and YrTr1; but virulent to Yr1, Yr2, Yr3, Yr4, Yr25, Yr44, and Yr76. The VPs of the parental isolate to nine Yr genes (Yr6, Yr7, Yr9, Yr17, Yr27, Yr28, Yr43, YrA, and YrExp2) and the avirulence phenotype to YrSP were found to be heterozygous. Based on the segregation of the virulence/avirulence phenotypes, we found that the VPs to Yr7, Yr28, Yr43, and YrExp2 were controlled by a dominant gene; those to Yr6, Yr9, and YrA (Yr73, Yr74) by two dominant genes; those to Yr17 and Yr27 by one dominant and one recessive gene; and the avirulence phenotype to YrSP by two complementary dominant genes. Molecular mapping revealed the linkage of 10 virulence/avirulence genes. Comparison of the inheritance modes of the virulence/avirulence genes in this study with previous studies indicated complex interactions between virulence genes in the pathogen and resistance genes in wheat lines. The results are useful for understanding the plant-pathogen interactions and developing wheat cultivars with effective and durable resistance. PMID- 29472942 TI - Function of Plant DExD/H-Box RNA Helicases Associated with Ribosomal RNA Biogenesis. AB - Ribosome biogenesis is a highly complex process that requires several cofactors, including DExD/H-box RNA helicases (RHs). RHs are a family of ATPases that rearrange the secondary structures of RNA and thus remodel ribonucleoprotein complexes. DExD/H-box RHs are found in most organisms and play critical roles in a variety of RNA-involved cellular events. In human and yeast cells, many DExD/H box RHs participate in multiple steps of ribosome biogenesis and regulate cellular proliferation and stress responses. In plants, several DExD/H-box RHs have been demonstrated to be associated with plant development and abiotic stress tolerance through their functions in modulating pre-rRNA processing. In this review, we summarize the pleiotropic roles of DExD/H-box RHs in rRNA biogenesis and other biological functions. We also describe the overall function of the DExD/H-box RH family in ribosome biogenesis based on data from human and yeast. PMID- 29472941 TI - Plant Abiotic Stress Proteomics: The Major Factors Determining Alterations in Cellular Proteome. AB - HIGHLIGHTS: Major environmental and genetic factors determining stress-related protein abundance are discussed.Major aspects of protein biological function including protein isoforms and PTMs, cellular localization and protein interactions are discussed.Functional diversity of protein isoforms and PTMs is discussed. Abiotic stresses reveal profound impacts on plant proteomes including alterations in protein relative abundance, cellular localization, post transcriptional and post-translational modifications (PTMs), protein interactions with other protein partners, and, finally, protein biological functions. The main aim of the present review is to discuss the major factors determining stress related protein accumulation and their final biological functions. A dynamics of stress response including stress acclimation to altered ambient conditions and recovery after the stress treatment is discussed. The results of proteomic studies aimed at a comparison of stress response in plant genotypes differing in stress adaptability reveal constitutively enhanced levels of several stress related proteins (protective proteins, chaperones, ROS scavenging- and detoxification-related enzymes) in the tolerant genotypes with respect to the susceptible ones. Tolerant genotypes can efficiently adjust energy metabolism to enhanced needs during stress acclimation. Stress tolerance vs. stress susceptibility are relative terms which can reflect different stress-coping strategies depending on the given stress treatment. The role of differential protein isoforms and PTMs with respect to their biological functions in different physiological constraints (cellular compartments and interacting partners) is discussed. The importance of protein functional studies following high-throughput proteome analyses is presented in a broader context of plant biology. In summary, the manuscript tries to provide an overview of the major factors which have to be considered when interpreting data from proteomic studies on stress-treated plants. PMID- 29472943 TI - Do Galactolipid Synthases Play a Key Role in the Biogenesis of Chloroplast Membranes of Higher Plants? AB - A unique feature of chloroplasts is their high content of the galactolipids monogalactosyldiacylglycerol (MGDG) and digalactosyldiacylglycerol (DGDG), which constitute up to 80% of their lipids. These galactolipids are synthesized in the chloroplast envelope membrane through the concerted action of galactosyltransferases, the so-called 'MGDG synthases (MGDs)' and 'DGDG synthases (DGDs),' which use uridine diphosphate (UDP)-galactose as donor. In Arabidopsis leaves, under standard conditions, the enzymes MGD1 and DGD1 provide the bulk of galactolipids, necessary for the massive expansion of thylakoid membranes. Under phosphate limited conditions, plants activate another pathway involving MGD2/MGD3 and DGD2 to provide additional DGDG that is exported to extraplastidial membranes where they partly replace phospholipids, a phosphate-saving mechanism in plants. A third enzyme system, which relies on the UDP-Gal-independent GGGT (also called SFR2 for SENSITIVE TO FREEZING 2), can be activated in response to a freezing stress. The biosynthesis of galactolipids by these multiple enzyme sets must be tightly regulated to meet the cellular demand in response to changing environmental conditions. The cooperation between MGD and DGD enzymes with a possible substrate channeling from diacylglycerol to MGDG and DGDG is supported by biochemical and biophysical studies and mutant analyses reviewed herein. The fine-tuning of MGDG to DGDG ratio, which allows the reversible transition from the hexagonal II to lamellar alpha phase of the lipid bilayer, could be a key factor in thylakoid biogenesis. PMID- 29472944 TI - Roles of E3 Ubiquitin-Ligases in Nuclear Protein Homeostasis during Plant Stress Responses. AB - Ubiquitination, the reversible protein conjugation with ubiquitin (Ub), is a post translational modification that enables rapid and specific cellular responses to stimuli without requirement of de novo protein synthesis. Although ubiquitination also displays non-proteolytic functions, it often acts as a signal for selective protein degradation through the ubiquitin-proteasome system (UPS). In plants, it has become increasingly apparent that the UPS is a central regulator of many key cellular and physiological processes, including responses to biotic and abiotic stresses. In the nucleus, protein regulation via the UPS orchestrates gene expression, genome maintenance, and signal transduction. Here, we focus on E3 Ub ligase proteins as major components of the ubiquitination cascade that confer specificity of substrate recognition. We provide an overview on how they contribute to nuclear proteome plasticity during plant responses to environmental stress signals.

PMID- 29472947 TI - Comparison of the Prevalence of Psychiatric Disorders in Performance-Enhancing Drug Users and Nonuser Bodybuilders. AB - Objective: The present study aimed at comparing the prevalence of major psychiatric disorders including major depressive disorder, bipolar disorder, schizophrenia, and generalized anxiety disorder between performance-enhancing drug users and nonuser bodybuilders. Moreover, the prevalence of major psychiatric disorders in bodybuilders was also reported. Method: In this study, 453 athletes were recruited from Bushehr bodybuilding gyms from February to May 2015. A structured questionnaire was used to collect the participants' information, including demographic characteristics, sports' status and performance-enhancing drug use. According to the condition of performance enhancing drug use, the participants were divided into current users, non-current users, and nonusers. The psychiatric status of the participants was evaluated using DSM-IV diagnostic criteria for major depressive disorder, bipolar disorder, generalized anxiety disorder, and schizophrenia. We also asked about the acute psychotic disturbances after using performance-enhancing drugs, alcohol use, and history of aggressive behavior in bodybuilders. Data were analyzed using one-way analysis of variance and chi-square tests. Results: Prevalence of major depressive disorder, bipolar disorder, schizophrenia, generalized anxiety disorder, and the overall prevalence of psychiatric disorders in the bodybuilders was 19.7%, 3.8%, 1.5%, 16.6%, and 26.7%, respectively. After using performance enhancing drugs, 33% of the bodybuilders had experienced acute psychological disturbances. There were no significant differences between current, non-current, and nonuser bodybuilding athletes in the measured psychiatric disorders. Conclusion: Prevalence of psychiatric disorders was not significantly different in performance-enhancing drug users and nonusers. Thus, it can be concluded that performance-enhancing drugs do not increase the risk of psychiatric disorders in bodybuilders. PMID- 29472946 TI - Heavy Chronic Intermittent Ethanol Exposure Alters Small Noncoding RNAs in Mouse Sperm and Epididymosomes. AB - While the risks of maternal alcohol abuse during pregnancy are well-established, several preclinical studies suggest that chronic preconception alcohol consumption by either parent may also have significance consequences for offspring health and development. Notably, since isogenic male mice used in these studies are not involved in gestation or rearing of offspring, the cross generational effects of paternal alcohol exposure suggest a germline-based epigenetic mechanism. Many recent studies have demonstrated that the effects of paternal environmental exposures such as stress or malnutrition can be transmitted to the next generation via alterations to small noncoding RNAs in sperm. Therefore, we used high throughput sequencing to examine the effect of preconception ethanol on small noncoding RNAs in sperm. We found that chronic intermittent ethanol exposure altered several small noncoding RNAs from three of the major small RNA classes in sperm, tRNA-derived small RNA (tDR), mitochondrial small RNA, and microRNA. Six of the ethanol-responsive small noncoding RNAs were evaluated with RT-qPCR on a separate cohort of mice and five of the six were confirmed to be altered by chronic ethanol exposure, supporting the validity of the sequencing results. In addition to altered sperm RNA abundance, chronic ethanol exposure affected post-transcriptional modifications to sperm small noncoding RNAs, increasing two nucleoside modifications previously identified in mitochondrial tRNA. Furthermore, we found that chronic ethanol reduced epididymal expression of a tRNA methyltransferase, Nsun2, known to directly regulate tDR biogenesis. Finally, ethanol-responsive sperm tDR are similarly altered in extracellular vesicles of the epididymis (i.e., epididymosomes), supporting the hypothesis that alterations to sperm tDR emerge in the epididymis and that epididymosomes are the primary source of small noncoding RNAs in sperm. These results add chronic ethanol to the growing list of paternal exposures that can affect small noncoding RNA abundance and nucleoside modifications in sperm. As small noncoding RNAs in sperm have been shown to causally induce heritable phenotypes in offspring, additional research is warranted to understand the potential effects of ethanol-responsive sperm small noncoding RNAs on offspring health and development. PMID- 29472948 TI - Craving and Drug Reward: A Comparison of Celecoxib and Ibuprofen in Detoxifying Opiate Addicts. AB - Objective: Craving for substance abuse is a usual and complicated problem in patients, with opioid addiction who are in opioid detoxifying process. Craving has been added as one of the diagnostic criteria of substance use disorders in DSM-5. The present trial aimed at comparing the effects of celecoxib versus ibuprofen in reducing pain and decreasing the desire to use opiates in patients undergoing opiate detoxification (n = 32). Method: A total of 32 patients (both inpatients and outpatients), who were undergoing opiate detoxification procedure and met the inclusion criteria entered this 4- week study. Participants who suffered from pain due to opiate withdrawal were randomized into 2 groups: Group 1 received celecoxib 200 milligrams once per day and group 2 received ibuprofen 400 milligrams 4 times per day. Self-reported Desire for Drug Questionnaire (DDQ) and 0-10 numeric pain scale were used at baseline and at the end of the study to evaluate changes in opiate craving and pain, respectively. Data analysis was done by SPSS-21 statistical software. Results: In this study, 16 patients received celecoxib 200 milligrams once daily, and 16 received ibuprofen 400 milligrams 4 times daily. After 4 weeks of treatment with both ibuprofen and celecoxib, the results revealed that celecoxib and ibuprofen equally reduced the pain symptoms. After 4 weeks of treatment, with either ibuprofen or celecoxib, significant improvement was observed in decreasing the craving in the celecoxib group, but not in the ibuprofen group. Conclusion: The study revealed a significant difference between the celecoxib and ibuprofen group in reducing craving in patients with opiate craving after 4 weeks of treatment. However there were no significant differences between these two groups in reducing pain. PMID- 29472949 TI - The Relationship between Motor, Imitation, and Early Social Communication Skills in Children with Autism. AB - Objective: Development of early social skills in children is a complex process. To understand this process, it is important to assess how strengths or weaknesses in other developmental domains may be affected by these skills. The present study aimed at investigating the association of motor skills and imitation ability with early social communication skills in children with autism spectrum disorder (ASD). Method: In this study, 20 children with ASD aged 3 to 5 years (M = 4.05, SD = 0.55) participated. All children were diagnosed as ASD based on the DSM-V criteria by an independent child psychiatrist. Additionally, Autism Diagnostic interview-Revised was used for subsequent diagnostic confirmation. Children were tested with Test of Gross Motor Development (TGMD-2), the Motor Imitation Scale (MIS), and the Early Social Communication Scales (ESCS). All examinations were videotaped for subsequent scoring. The relationship between these skills was estimated by Pearson correlation coefficient. Results: A significant and strong correlation was obtained between TGMD total score and imitation total score (r =.776; p <0.001). However, the relationship between MIS subscales and TGMD-2 locomotor subtest scores was not significant (P>0.05). A significant correlation was found between MIS and TGMD total scores with Initiating Joint Attention and Responding to Joint Attention (p<=0/025) as ESCS subscales. But MIS and TGMD total scores were not correlated with social interaction and responding to behavioral requests subscales. Conclusion: The results of the present study showed that indicated both imitation ability and motor function have an association with each other and with early social communication skills.

AB - Objective: Food choice is a process through which people think, feel, and eat food. It does not only influence individuals' health and well-being, families and communities, but also it has an effect on regional, national, and global levels. This qualitative study was conducted to explore perceptions and lived experiences of Tehran adult residents on psychological, social and cultural determinants of food choice. Method: In this qualitative design, we recruited 33 adults aged 30 to 64 years from various districts of Tehran, capital of Iran, and we explored how people make decisions about food choice in practice and shape their perception, attitude, and eating practices. An individual in-depth semi structured interview guide included major questions with follow-up probes was used to explore participants' current and past eating habits from childhood to adulthood, dietary change at different life courses, and effective psychological state on food selection in different seasons. Results: This study revealed that food choice in the studied adults (30-64 years old) was widely influenced by psychological, social, and cultural determinants, which can be categorized into 5 main themes: cultural context and patterns; social Structure and norms; information resources and media; household and family structure; and nutrition transition. Conclusion: The findings clarified the importance of social and cultural contexts, which influence the food choice of adults in a metropolis like Tehran. Many of these concepts are contextualized from childhood. These findings could serve as guideline to design socio-culturally appropriate strategies and improve dietary behaviors of Iranians. PMID- 29472951 TI - Psychiatric Disorders and Personality Profiles of Middle-Aged Suicide Attempters with No Evidence of Specific Psychopathological Profiles Referred to an Emergency Department. AB - Objective: The present study aimed at assessing the sociodemographic and psychiatric characteristics of 40 to 65 year- old suicide attempters, who were referred to an emergency department within 4 hours of the attempt. Method: A total of 93 suicide attempters (Mean age=46.59 years) who were referred to an emergency department, were assessed in this study. Patients completed questionnaires covering sociodemographic data, personality traits, mood, and impulsivity. Psychiatric status of the patients was rated by experts. Results: Experts rated 85 (92.4%) of the suicide attempters as having a psychiatric disorder. Based on self-ratings and compared to normative data, 42 (46.6%) patients were psychopathologically ill. It was found that suicide attempts were not related to impulsive personality traits, mood disorders, sociodemographic patterns, or gender (gender-ratio: 1:1.58; f: m). Conclusion: The pattern of results suggests that further unknown factors were involved in pushing people to attempt suicide.

AB - Objective: Spiritual psychotherapy has been conceptualized in the context of love and belief as principles of existence. Spiritual psychotherapy can provide an opportunity to design programs to treat conduct disorder. The aim of this study was to introduce the Spiritual Psychotherapy Package for Adolescents with Conduct Disorder and execute it as a pilot study. Method: The intervention is a manual guided program conducted over 14 group sessions, using the perspectives of object relations and attachment approach. It was executed for a group of eight adolescent boys with conduct disorder (mean age: 17.01 years) at Tehran reformatory. The Aggression Questionnaire and the Attachment to God Inventory were completed pre- and post-intervention. Results: There were no significant differences in outcome measures from pre- to post- intervention. Cohen's dav was applied to estimate the measure of the effect size in this study. Cohen's dav measures of avoidance and anxious attachment to God showed acceptable effect sizes. However, Cohen's dav measure of verbal aggression indicated a small effect size. Conclusion: We found evidence indicating acceptability of spiritual psychotherapy among adolescents with conduct disorder in attachment to God. PMID- 29472953 TI - Catechol-O-Methyltransferase (COMT) Gene (Val158Met) and Brain-Derived Neurotropic Factor (BDNF) (Val66Met) Genes Polymorphism in Schizophrenia: A Case Control Study. AB - Objective: Several studies have shown that some polymorphisms of genes encoding catechol-O-methyltransferase (COMT), the key enzyme in degrading dopamine, and norepinephrine and the human brain-derived neurotropic factor (BDNF), a nerve growth factor, are strong candidates for risk of schizophrenia (SCZ). In the present study, we aimed at examining the effects of COMT Val158Met (G>A) and BDNF Val66Met (G>A) polymorphisms on SCZ risk in a sample of Iranian population. Method: This case- control study included 92 SCZ patients and 92 healthy controls (HCs). Genotyping of both variants (COMT Val158Met (G>A) and BDNF Val66Met (G>A)) were conducted using Amplification Refractory Mutation System-Polymerase Chain Reaction (ARMS-PCR). Results: The findings revealed that the COMT Val158Met (G>A) polymorphism was not associated with the risk/protective of SCZ in all models (OR=0.630, 95%CI=0.299-1.326, P=0.224, GA vs. GG, OR=1.416, 95%CI=0.719-2.793, P=0.314, AA vs. GG, OR=1.00, 95%CI=0.56-1.79, P=1.00 GA+AA vs. GG, OR=1.667, 95%CI=0.885-3.125, P=0.11, AA vs. GG+GA, OR=1.247, 95%CI=0.825-1.885, P=0.343, A vs. G,). However, BDNF Val66Met (G>A) variant increased the risk of SCZ (OR = 2.008 95%CI = 1.008-4.00, P = 0.047, GA vs. GG, OR = 3.876 95%CI = 1.001-14.925, P = 0.049. AA vs. GG, OR = 2.272. 95%CI = 1.204-4.347, P = 0.011, GA+AA vs. GG, OR = 2.22 95%CI = 1.29-3.82. P = 0.005, A vs. G). Conclusion: The results did not support an association between COMT Val158Met (G>A) variant and risk/protective of SCZ. Moreover, it was found that BDNF Val66Met (G>A) polymorphism may increase the risk of SCZ development. Further studies and different ethnicities are recommended to confirm the findings. PMID- 29472954 TI - Evaluation of the Effectiveness of the Friends for Life Program on Children's Anxiety and Depression. AB - Objective: Anxiety disorders and depression during childhood and adolescence are among highly prevalent serious mental health problems, which lead to reduced performance in children and can also negatively affect children's emotional and social long-term development. This study, which was conducted in Mashhad in 2015, aimed at evaluating the effectiveness of the Friends for Life cognitive behavioral program in reducing the symptoms of anxiety and depression in children. Method: In this controlled clinical trial, 248 male students aged 10 were screened for mild to moderate symptoms of anxiety and depression using the Revised Children's Manifest Anxiety (RCMA) and the Children's Depression Inventory (CDI). Of the participants, 40 students met the inclusion criteria. The demographic questionnaire, the Strengths and Difficulties Questionnaire (SDQ), and the Depression-Anxiety-Stress Scale (DASS) were filled out by parents. The children in the experimental group received the Friends for Life cognitive behavioral training program for eight 1-hour weekly sessions. RCMA, CDI, SDQ, and DASS were filled out again by both groups at the end of the sessions and 3 months later. To evaluate comparability between the 2 groups, Mann-Whitney test was used for qualitative variables and paired t test and repeated measure for quantitative variables with normal distribution. Statistical analysis was performed using SPSS 16. All statistical references were made at ?=0.05. Results: Children's depression and manifest anxiety scores were not significantly different in the 2 groups before the intervention; however, their changes immediately after intervention and at the 3- month follow-up were significant (p<0.001). Moreover, hyperactivity (p = 0.039), peer problems (p = 0.011), and parental depression (p = 0.015) scores significantly changed in both groups over time. Conclusion: Implementation of Friends for Life program is effective in prevention and treatment of the symptoms of anxiety and depression in children. PMID- 29472955 TI - Improving Depression, and Quality of Life in Patients with Type 2 Diabetes: Using Group Cognitive Behavior Therapy. AB - Objective: Depression is a chronic condition comorbid with diabetes type 2 that often remains untreated. Dealing with diabetes is a challenging task for patients and can lead to depression in long term. These two conditions have a negative influence on each other and on the individual's quality of life. The purpose of this study was to investigate the effect of group cognitive behavior therapy on depression, quality of life in women with diabetes type 2. Method: We conducted a clinical trial among 30 women with diabetes type 2 comorbid with depression. The women were divided randomly into the two groups of intervention and control. Each group consisted of 15 individuals. The intervention group received 10 sessions of group cognitive behavior therapy while the control group didn't. Results: The results suggested that group cognitive-behavior therapy decreased depression symptoms (F=72.17, p<0.001), and improved quality of life of the patients (F=8.82, p<0.05) of the intervention group compared to the control group. Conclusion: The results shows that group cognitive behavior therapy can affect depression symptoms, and consequently patients' quality of life with diabetes type 2. PMID- 29472956 TI - Adherence to Guideline Recommendations in Patients with Thyroid Nodules. AB - Introduction: Thyroid nodules are common and fine-needle aspiration (FNA) biopsy is the standard of care for work-up to exclude thyroid cancer. In this study, we examined the discrepancy between daily practice and recommended diagnostic approach for management of thyroid nodules, based on history taking, laboratory, and imaging studies. Methods: This was a retrospective chart review of 199 patients who had ultrasound-guided fine needle aspiration (UGFNA) performed at a Midwest academic medical center from January 2010 to December 2011. The quality measures were selected based on recommended clinical practice guidelines, including family history, history of neck radiation, neck symptoms, TSH test, and thyroid ultrasound. Results: The majority of patients were Caucasian females. Family history of thyroid cancer and childhood neck radiation exposure were documented in 79 subjects (40%) and 76 subjects (38%), respectively. Neck symptoms were documented in most subjects, including dysphonia (56.8%), dysphagia (69.9%), and dyspnea (41.2%). Most subjects had a TSH measured and an ultrasound performed prior to biopsy (75% and 86%, respectively). Conclusions: It appears there is a gap between current patient care and clinical practice guidelines for management of thyroid nodules. Clinical history and ultrasound features for risk stratification of UGFNA were lacking, which could reflect physicians' unfamiliarity with the guidelines. As thyroid nodules are common, enhancing knowledge of the current guidelines could improve appropriate work-up. Further studies are needed to identify factors associated with the poor compliance with clinical guidelines in management of thyroid nodules. PMID- 29472957 TI - Direct Primary Care in 2015: A Survey with Selected Comparisons to 2005 Survey Data. AB - Introduction: Direct primary care (DPC), a fee for membership type of practice, is an evolving innovative primary care delivery model. Little is known about current membership fees, insurance billing status, physician training, and patient panel size in DPC practices. This study aimed to obtain current data for these variables, as well as additional demographic and financial indicators, and relate the findings to the Healthy People 2020 goals. It was predicted that DPC practices would (1) submit fewer claims to insurance, (2) have decreased membership fees, (3) be primarily family medicine trained, and (4) have increased the projected patient panel size since 2005. Methods: An electronic survey was sent to DPC practices (n = 65) requesting location, membership fees, projected patient panel size, insurance billing status, training, and other demographic and financial indicators. Data were aggregated, reported anonymously, and compared to two prior characterizations of DPC practices done in 2005. Results: Thirty-eight of 65 (59%) practices responded to the 2015 survey. The majority of respondents (84%) reported using an EMR, offering physician email access (82%), 24-hour access (76%), same day appointments (92%), and wholesale labs (74%). Few respondents offered inpatient care (16%), obstetrics (3%), or financial/insurance consultant services. Eighty-eight percent (88%) of practices reported annual individual adult membership rates between $500 and $1,499, decreased from 2005 where 81% reported greater than a $1,500 annual fee. The proportion of practices who submit bills to insurance decreased from 75% in 2005 to 11% in 2015. Fifty six percent (56%) of practices reported projected patient panel size to be greater than 600, increased from 40% in 2005. Family medicine physicians represented 87% of respondents, markedly different from 2005 when 62 - 77% of DPC respondents were general internal medicine physicians. Conclusions: Most DPC practices no longer submit to insurance and are family medicine trained. Compared with the previous sampling, DPC practices report decreased membership fees and increased projected panel size. These trends may signify the DPC movement's growth in application and scope. PMID- 29472958 TI - An Evaluation of SmokeFree for Kansas Kids: An Intervention to Promote Tobacco Cessation in Pediatric Clinics. AB - Introduction: Smokefree for Kansas Kids is a program designed to train pediatric clinic staff to assess for tobacco exposure and provide brief smoking cessation interventions to caregivers and patients. The purpose of this study was to evaluate the impact of this program and improve future tobacco intervention efforts in pediatric clinics. Method: Eighty-six pediatric physicians and staff attended at least one of three training sessions. A random sample of pediatric medical records was selected pre-intervention (n = 49) and post-intervention (n = 150). Electronic medical records were reviewed to assess for documentation of tobacco use intervention implemented in the clinic. Results: Of the 199 pediatric clinic visits reviewed, 197 met the study criteria. All but one visit documented an assessment of tobacco exposure. Among children exposed to tobacco (n = 42), providers were more likely to discuss tobacco use with caregivers post intervention (35.7%) compared to pre-intervention (7.1%; p < 0.05). One in five caregivers in the post-intervention group were advised to quit (21.4%) compared to the pre-intervention group (7.1%). In the post-intervention group, 14.3% were referred to the state quitline compared to no referrals in the pre-intervention group. The difference in rates for providing advice and referral between pre intervention and post-intervention were not statistically significant. Conclusions: Implementation of the Smoke Free for Kansas Kids intervention was associated with modest improvements in clinic tobacco intervention efforts, but many patients still failed to receive optimal assessments or interventions. Additional efforts may be needed to enhance this program. PMID- 29472959 TI - Successes and Challenges of Optimal Trauma Care for Rural Family Physicians in Kansas. AB - Introduction: Kansas has a regionalized trauma system with formal mechanisms for review, however, increased communication with rural providers can uncover opportunities for system process improvement. Therefore, this qualitative study explored perceptions of family medicine physicians staffing emergency departments (ED) in rural areas, specifically to determine what is going well and what areas needed improvement in relation to the trauma system. Methods: A focus group included Kansas rural family physicians recruited from a local symposium for family medicine physicians. Demographic information was collected via survey prior to the focus group session, which was audiotaped. Research team members read the transcription, identified themes, and grouped the findings into categories for analysis. Results: Seven rural family medicine physicians participated in the focus group. The majority were male (71%) with the mean age 46.71 years. All saw patients in the ED and had treated injuries due to agriculture, falls, and motor vehicle collisions. Participants identified successes in the adoption and enforcement of standardized processes, specifically through level IV trauma center certification and staff requirements for Advanced Trauma Life Support training. Communication breakdown during patient discharge and skill maintenance were the most prevalent challenges. Conclusions: Even with an established regionalized trauma system in the state of Kansas, there continues to be opportunities for improvement. The challenges acknowledged by focus group participants may not be identified through patient case reviews (if conducted), therefore tertiary centers should conduct system reviews with referring hospitals regularly to improve systemic concerns.

PMID- 29472963 TI - The Relationship of Personality Style and Attention Deficit Hyperactivity Disorder in Children. AB - Introduction: This study was to identify personality correlates of children with a diagnosis of Attention Deficit Hyperactive Disorder (ADHD). The Jungian Personality Type dimensions primarily considered were Sensing/Intuiting and Perceiving/Judging. A Sensing child is likely to be very present-centered. A Perceiving child tends to be curious and resist order and structure. Methods: Children attending a general pediatric clinic with a diagnosis of ADHD were eligible to participate. Enrolled children were administered the Murphy-Meisgeier Type Indicator for Children. Binomial tests were performed comparing Perceiving and Sensing personality components to accepted population rates. Results: Participants (n = 117) were predominantly male (78%) with a median age of 10 years. The Sensing trait (72%) was more prevalent than expected, though prevalence for the Perceiving trait (44%) did not differ from population rates. Conclusion: Personality types occasioned with the diagnosis of ADHD could be useful in establishing/normalizing treatment regimens and approaches to assist these children and their families better. PMID- 29472964 TI - Functional Outcomes of Thoracolumbar Junction Spine Fractures. AB - Introduction: Few studies have evaluated the functional outcomes of traumatic thoracic and lumbar vertebral body fractures. This study evaluated the functional and clinical outcomes of patients, who sustained a fracture to the thoracolumbar area of the spine (T10 to L2 region), with >= 25 degrees kyphosis versus those with less kyphotic curvature. Methods: The trauma registry records of two level 1 trauma centers using ICD-9 codes for fracture to the thoracolumbar juncture (T10 to L2 region) were reviewed. Kyphosis angle was measured on the standing lateral thoracolumbar (T1 - L5) radiograph at initial trauma and at clinical follow-up. Functional outcome questionnaires, including the Oswestry Disability Questionnaire (ODQ), the Roland Morris Disability Questionnaire (RMDQ), and the Nottingham Health Profile (NHP), were evaluated at clinical follow-up. Work status and medication used after trauma also were recorded. Results: A total of 38 patients met the inclusive criteria. Seventeen patients (45%) had >= 25 degrees kyphosis and 21 patients (55%) had < 25 degrees kyphosis at follow-up. These two groups were similar based on sex and age. Based on the ODQ Score, the RMDQ Score, and the NHP, no statistically significant differences were detected between the two groups in regards to energy, pain, mobility, emotional reaction, social isolation, and sleep. Conclusions: Patients who sustained a fracture to the thoracolumbar area of the spine with >= 25 degrees kyphosis do not report worse clinical outcomes. When using the kyphosis angle as an indication for surgery, it should be used with caution and not exclusively. PMID- 29472965 TI - Validation of Different Combination of Three Reversing Half-Hitches Alternating Posts (RHAPs) Effects on Arthroscopic Knot Integrity. AB - Introduction: With arthroscopic techniques being used, the importance of knot tying has been examined. Previous literature has examined the use of reversing half-hitches on alternating posts (RHAPs) on knot security. Separately, there has been research regarding different suture materials commonly used in the operating room. The specific aim of this study was to validate the effect of different stacked half-hitch configuration and different braided suture materials on arthroscopic knot integrity. Methods: Three different suture materials tied with five different RHAPs in arthroscopic knots were compared. A single load-to failure test was performed and the mean ultimate clinical failure load was obtained. Results: Significant knot holding strength improvement was found when one half-hitch was reversed as compared to baseline knot. When two of the half hitches were reversed, there was a greater improvement with all knots having a mean ultimate clinical failure load greater than 150 newtons (N). Comparison of the suture materials demonstrated a higher mean ultimate clinical failure load when Force Fiber(r) was used and at least one half-hitch was reversed. Knots tied with either Force Fiber(r) or Orthocord(r) showed 0% chance of knot slippage while knots tied with FiberWire(r) or braided fishing line had about 10 and 30% knot slippage chances, respectively. Conclusions: A significant effect was observed in regards to both stacked half-hitch configuration and suture materials used on knot loop and knot security. Caution should be used with tying three RHAPs in arthroscopic surgery, particularly with a standard knot pusher and arthroscopic cannulas. The findings of this study indicated the importance of three RHAPs in performing arthroscopic knot tying and provided evidence regarding discrepancies of maximum clinical failure loads observed between orthopaedic surgeons, thereby leading to better surgical outcomes in the future. PMID- 29472966 TI - A Preliminary Study of the Attitudes and Barriers of Family Physicians to Prescribing HIV Preexposure Prophylaxis. AB - Introduction: Attitudes of individuals who provide HIV care towards prescribing Preexposure Prophylaxis (PrEP) to at-risk populations have been studied, but few studies indicate if family physicians would be willing to prescribe PrEP as most family physicians do not specialize in HIV medicine. Few data exist on the perceived barriers preventing family physicians from prescribing PrEP. The purpose of this project was to assess the attitudes and perceived barriers of family physicians in Kansas towards prescribing PrEP to high risk patient populations. Methods: This study was a descriptive, observational, and cross sectional survey of family physicians who respond to email surveys issued through the Family Medicine Research and Data Information Office (FM RADIO). Results: Fifty-three percent of family physicians take a sexual history on new patients less than frequently, and only 35% frequently ask about the use of safe sex practices. Only 29% frequently ask if the patient has sex with men, women, or both. Seventy-six percent of respondents would be willing to prescribe PrEP to men who have sex with men, and an equal percentage would be willing to prescribe to heterosexually active men and women who are at substantial risk of acquiring HIV. While 59% of participants agreed that PrEP belongs in the primary care domain of treatment, 71% agreed that they had limited or no knowledge of PrEP guidelines. Conclusions: This preliminary study indicated a need for increased family physician screening of new patients for high risk sexual behaviors who would be eligible for PrEP. The limited knowledge of PrEP guidelines and its use in clinical practice are significant limiting factors to increasing prescribing practices in the family medicine community rather than a perceived ethical dilemma of prescribing PrEP to men who have sex with men. As a result, an increase in continuing medical education about PrEP could significantly increase its prescribing in the family medicine community.

PMID- 29472969 TI - Student Expenses in Residency Interviewing. AB - Background: The student costs of residency interviewing are of increasing concern but limited current information is available. Updated, more detailed information would assist students and residency programs in decisions about residency selection. The study objective was to measure the expenses and time spent in residency interviewing by the 2016 graduating class of the University of Kansas School of Medicine and assess the impact of gender, regional campus location, and primary care application. Methods: All 195 students who participated in the 2016 National Residency Matching Program (NRMP) received a 33 item questionnaire addressing interviewing activity, expenses incurred, time invested and related factors. Main measures were self-reported estimates of expenses and time spent interviewing. Descriptive analyses were applied to participant characteristics and responses. Multivariate analysis of variance (MANOVA) and chi-square tests compared students by gender, campus (main/regional), and primary care/other specialties. Analyses of variance (ANOVA) on the dependent variables provided follow-up tests on significant MANOVA results. Results: A total of 163 students (84%) completed the survey. The average student reported 38 (1-124) applications, 16 (1-54) invitations, 11 (1-28) completed interviews, and spent $3,500 ($20 $12,000) and 26 (1-90) days interviewing. No significant differences were found by gender. After MANOVA and ANOVA analyses, non-primary care applicants reported significantly more applications, interviews, and expenditures, but less program financial support. Regional campus students reported significantly fewer invitations, interviews, and days interviewing, but equivalent costs when controlled for primary care application. Cost was a limiting factor in accepting interviews for 63% and time for 53% of study respondents. Conclusions: Students reported investing significant time and money in interviewing. After controlling for other variables, primary care was associated with significantly lowered expenses. Regional campus location was associated with fewer interviews and less time interviewing. Gender had no significant impact on any aspect studied. PMID- 29472970 TI - Comparisons of Medical Student Knowledge Regarding Life-Threatening CT Images Before and After Clinical Experience. AB - Background: Currently, no national standard exists for educating medical students regarding radiography or formal research indicating the level of improvement regarding computed tomography (CT) interpretation of medical students during clinical rotations. Methods: Students were evaluated based on their response to twenty-two open-ended questions regarding diagnosis and treatment of eleven de identified CT images of life-threatening injuries. The number of incorrect answers was compared with correct or partially correct answers between students starting third-year clinical rotations and those starting their fourth year. Results: Survey results were collected from 65 of 65 (100%) beginning third-year students and 9 of 60 (15%) beginning fourth-year students. Students in their fourth-year had less incorrect answers compared to third-year students, with five questions reflecting a statistically significant reduction in incorrect responses. The image with the least incorrect for both groups was epidural hemorrhage, 33.9% and 18.5% incorrect for third-year students for diagnosis and treatment, respectively, and 11.1% and 0% incorrect for fourth-year students. Outside of this image, the range of incorrect answers for third-year students was 75.4% to 100% and 44.4% to 100% for fourth-year students. Conclusion: Baseline CT knowledge of medical students, regardless of clinical experience, indicated a strong deficit, as more students were incorrect than correct for the majority of CT images. PMID- 29472971 TI - Safe Sleep Knowledge and Use of Provided Cribs in a Crib Delivery Program. AB - Background: Risk of infant sleep-related death can be reduced through safe sleep practices. Barriers to infant safe sleep have been mitigated through education and crib distribution, however, previous studies have not explored whether distributed cribs are put to use. Methods: In a rural Michigan county, the Great Start Sleep Initiative supplied cribs and education shortly after infant birth to families with high-risk of infant mortality, as assessed through comprehensive interviews with families by program staff. Participant knowledge was evaluated using structured pre- and post-assessments before and after education. Further, a home visit was conducted to evaluate the infant's sleeping environment. Data from the program, collected between January 2012 and December 2014, was evaluated. Results: Cribs and concomitant education were delivered to 75 caregivers. Knowledge of safe sleep practices increased significantly at follow-up with 67 caregivers (89%) affirming back positioning, 68 (91%) endorsing removal of unsafe items or soft objects, such as blankets, from the sleeping area, and 42 (56%) renouncing bed-sharing. At the home visit, 74 caregivers (99%) were using a crib to put their infant down to sleep, 70 (93%) were using the provided crib, and 67 (89%) had no unsafe items in the child's sleeping area. Conclusions: Providing education to high-risk mothers resulted in improved safe sleep knowledge and provided cribs are used in these homes. PMID- 29472972 TI - Bone Health Improvement Protocol. AB - Introduction: Metabolic bone disease is a malady that causes significant morbidity and mortality to a patient who has sustained a fragility fracture. There is currently no protocol to prevent secondary fragility fracture at our institution. The objective of this study was to create an appropriate protocol for implementing clinical pathways for physicians to diagnose and treat osteoporosis and fragility fractures by educating patients. Methods: A multidisciplinary team created an appropriate protocol that could be implemented in an inpatient setting. A thorough literature review was conducted to evaluate potential barriers and efficacious methods of protocol design. Results: A bone health improvement protocol was developed. Any patient over the age of 50 who sustains a fracture from low energy trauma, such as a fall from standing or less, should be considered to place into this protocol. These patients received education on metabolic bone disease, a prescription for high dose vitamin D therapy, and laboratory testing to determine the etiology of their metabolic bone disease. Continuity of care of these patients with their primary care provider was provided for further management of their metabolic bone disease and evaluation of their disease after discharged from the hospital. Discussion: Comprehensive secondary prevention should consist of osteoporosis assessment and treatment together with a fall risk assessment. With this protocol, secondary fragility fractures potentially could be prevented.

AB - Introduction: All-terrain vehicles (ATVs) are associated with injury, mortality, and healthcare costs. ATV related injuries are less severe when consistent safety practices are followed, however, ATV safety regulations are varied among states. This study sought to survey Kansas ATV dealers and track owners to determine safety promotion practices. Methods: A cross-sectional telephone survey was conducted of Kansas ATV dealers and tracks. Survey questions included promotion and sale of safety equipment, provision of ATV safety information, and respondent characteristics. Results: Of those contacted, 32% of dealers and 31% of tracks responded to the survey. Most ATV dealers sell safety gear (70% - 100%) and all recommend safety gear to buyers and riders. All ATV tracks reported requiring helmets (100%) but were varied regarding other forms of safety gear. The majority of ATV dealers (77%) recommended safety courses, but only 31% of dealers and 40% of tracks offered courses. Eighty percent of ATV tracks and 52% of dealers felt they had a professional responsibility to educate riders/owners on safety. Conclusion: Safety promotion by ATV dealers in Kansas consistently was recommended, but often limited to the sales of safety gear (helmets and gloves) or the provision of manufacturer provided safety materials. Further, ATV dealers reported rarely offering skills tests or safety courses to buyers. In Kansas, safety promotion at the point of sale or track level could be improved to increase public awareness of ATV safety practices. PMID- 29472977 TI - Rural Kansas Family Physician Satisfaction with Caring for Spanish-Speaking Only Patients. AB - BACKGROUND: Patient satisfaction with the care they receive can be influenced negatively by a language barrier between the physician and patient. However, there is a paucity of information regarding the consequences of a language barrier on physician satisfaction, although this barrier has the potential to decrease physician wellness. This study sought to determine if a language barrier is a source of professional dissatisfaction in family medicine physicians in rural Kansas. METHODS: In a cross-sectional study, members of the Kansas Academy of Family Physicians who practiced in the rural Kansas counties with the highest percentage of Hispanic residents were surveyed. A questionnaire was developed to determine the demographics of the physician, details regarding his or her practice, and percentage of Hispanic and Spanish-speaking only (SSO) patients in their practice. Physicians also were queried as to their level of Spanish speaking ability, availability of certified interpreters, and their satisfaction with caring for their SSO patients. RESULTS: Fifty-two physicians were identified and sent questionnaires by mail. Eighteen questionnaires were completed and returned, resulting in a 34% response rate. Respondents remained anonymous. In the practices surveyed, 61% of practice settings had a Hispanic-patient population greater than 25%. Only one of the eighteen respondents had greater than 25% of SSO patients in his or her practice. A certified interpreter was used less than 25% of the time in over 75% of the clinical encounters with SSO patients. Seventy-five percent of physicians reported no difficulty establishing trust and rapport with their SSO patients. Eighty-nine percent of respondents rated their relationship with SSO patients as good to excellent, and 83% were satisfied with the care they were able to provide this group. Seventy-eight percent of respondents reported that their ability to care for SSO patients decreased or had no effect on their professional satisfaction. Seventy-eight percent of physicians also rated their overall professional satisfaction in regards to their physician/patient relationship as good to excellent. However, language barriers affected physician-patient relationships, physician satisfaction with care, and professional satisfaction. CONCLUSION: Language barrier affected physician's relationships with SSO patients, led to decreased physician satisfaction with the care they provided and to decreased professional satisfaction. PMID- 29472978 TI - Kansas Provider Report of Adolescent Vaccinations in Their Practice. AB - Background: Kansas falls consistently below average for adolescent vaccination of meningococcal (MCV), human papillomavirus (HPV), and influenza. Methods: For this study, the members of Kansas Chapter of the American Academy of Pediatrics were emailed a confidential electronic survey soliciting their impressions of vaccination in their practice. Results: Of 137 providers emailed, 61 (45%) completed the survey. Thirteen providers were excluded as they did not see/vaccinate adolescents or did not complete the survey. Tetanus, diphtheria, pertussis (Tdap), and MCV vaccines were most commonly up to date with 31 (65%) and 20 (42%) respondents reporting greater than 90% immunization rates, respectively. HPV (n = 42, 89%) and influenza (n = 40, 83%) vaccines had refusal rates greater than 25% in most clinics. Most practices (n = 44, 92%) used internal electronic medical records to track vaccinations, although 29 practices (60%) utilized the state immunization information system. Providers requested vaccine-specific patient education tools, positive media coverage, staffing support, and best-practices workshops to support vaccination efforts. Conclusion: Kansas providers may not be optimizing available resources to enhance these rates, such as Web IZ tracking and immunization reminders. Patient education supplies, specific to HPV and Influenza vaccination, potentially could increase vaccination rates. PMID- 29472979 TI - Barriers to Utilizing Medicaid Smoking Cessation Benefits. AB - Introduction: Smoking is the number one preventable cause of death in the United States. Under the Affordable Care Act, Kansas Medicaid covers all seven FDA approved smoking cessation therapies. However, it is estimated only 3% of Kansas Medicaid smokers use treatment compared to the national estimate of 10%. The objective is to determine systemic barriers in place that prevent optimal utilization of Medicaid smoking cessation benefits among KU Medical Center Internal Medicine patients. Methods: For this quality improvement project, a population of 169 Kansas Medicaid smokers was identified who had been seen at the KU Internal Medicine Clinic from January 1, 2015 - February 16, 2016. Phone surveys were completed with 62 individuals about smoking status, interest in using smoking cessation treatment options, and awareness of Medicaid coverage of treatment. Results: Of the 62 respondents, 24 (39%) were prescribed pharmacotherapy and 41 (66%) were interested in using smoking cessation treatment. There were eight who had quit smoking. Of the remaining 54 smokers, 31 (57%) were unaware that Medicaid would cover pharmacotherapy. Of 24 participants who received a prescription for pharmacotherapy, 13 (54%) were able to fill the prescription at no cost using the Medicaid benefit. Conclusions: The majority of respondents were interested in using smoking cessation treatment yet three main barriers existed to using Medicaid smoking cessation benefits: physicians not prescribing treatment to patients, patients not aware of Medicaid coverage, and inadequate pharmacy filling. Improved physician and patient awareness of Medicaid coverage will facilitate more patients receiving smoking cessation therapy and ultimately quitting smoking. PMID- 29472980 TI - Pediatric Farm Injuries: Morbidity and Mortality. AB - Background: Agriculture is an industry where family members often live and work on the same premises. This study evaluated injury patterns and outcomes in children from farm-related accidents. Methods: A 10-year retrospective review of farm-accident related injuries was conducted of patients 17 years and younger. Data collected included demographics, injury mechanism, accident details, injury severity and patterns, treatments required, hospitalization details, and discharge disposition. Results: Sixty-five patients were included; 58.5% were male and the mean age was 9.7 years. Median Injury Severity Score and Glasgow Coma Scale were 5 and 15, respectively. Accident mechanisms included animal related (43.1%), fall (21.5%), and motor vehicle (21.5%). Soft tissue injuries, concussions and upper extremity fractures were the most common injuries observed (58.5%, 29.2%, and 26.2%, respectively). Twenty-six patients (40%) required surgical intervention. Mean hospital length of stay was 3.4 +/- 4.7 days. The majority of patients were discharged to home (n = 62, 95.4%) and two patients suffered permanent disability. Conclusions: Overall, outcomes for this population were favorable, but additional measures to increase safety, such as fall prevention, animal handling, and driver safety training should be advocated.

AB - I define big data with respect to its size but pay particular attention to the fact that the data I am referring to is urban data, that is, data for cities that are invariably tagged to space and time. I argue that this sort of data are largely being streamed from sensors, and this represents a sea change in the kinds of data that we have about what happens where and when in cities. I describe how the growth of big data is shifting the emphasis from longer term strategic planning to short-term thinking about how cities function and can be managed, although with the possibility that over much longer periods of time, this kind of big data will become a source for information about every time horizon. By way of conclusion, I illustrate the need for new theory and analysis with respect to 6 months of smart travel card data of individual trips on Greater London's public transport systems. PMID- 29472984 TI - Factors influencing prospective mother with prenatal qualified doctor care among the reproductive women in Bangladesh. AB - Maternal and child mortality are the key indicators of health and development of the country. Maternal and child health are interconnected to prenatal care. Consulting a doctor at the prenatal stage will not only ensure mother's and her unborn babies' safety, but also has a great influence to reduce the maternal and infant mortality. In this paper, an attempt has been made to analyze the status of prenatal care provided by the qualified doctor among pregnant mothers in Bangladesh. Data and required information of 8793 reproductive women were collected from the Bangladesh Demographic and Health Survey (BDHS) 2014. Logistic regression model has been used to identify the most significant determinants of the prenatal doctor visits. In this research, it is found that prenatal cares by a qualified doctor during pregnancy depend on several social and demographic characteristics of a woman. It is observed that women staying both urban and rural areas have similar behaviour of caring regarding their pregnancy related complications. Beside this Respondent's age, education, her husband's education and the number of ever born children have significant contribution on prenatal doctor visit. On the other hand, division, religion, husband's desire for children has no effect on it. Overall the model is able to predict 71.65% women into their appropriate group based on these factors.

The report highlights the difficulties that one may encounter when managing such a case in regards to patient symptoms, side effects of medications and the relapsing nature of the condition. The case report also highlights novel treatment in the treatment of Riedel's thyroiditis, rituximab, how this works and the resolution of symptoms that we have achieved with our patient on this treatment. Learning points: Riedel's thyroiditis is characterised by chronic inflammation, which causes dense fibrosis in the thyroid gland.Riedel's thyroiditis can present with neck pain, dysphagia and dyspnoea with a firm, non tender mass found on examination.Riedel's thyroiditis is part of the IgG4-related systemic disorders.Rituximab is a monoclonal antibody that works against the protein CD20.

AB - : Early-onset acromegaly causing gigantism is often associated with aryl hydrocarbon-interacting receptor protein (AIP) mutation, especially if there is a positive family history. A15y male presented with tiredness and visual problems. He was 201 cm tall with a span of 217 cm. He had typical facial features of acromegaly, elevated IGF-1, secondary hypogonadism and a large macroadenoma. His paternal aunt had a history of acromegaly presenting at the age of 35 years. Following transsphenoidal surgery, his IGF-1 normalized and clinical symptoms improved. He was found to have a novel AIP mutation destroying the stop codon c.991T>C; p.*331R. Unexpectedly, his father and paternal aunt were negative for this mutation while his mother and older sister were unaffected carriers, suggesting that his aunt represents a phenocopy. Learning points: Typical presentation for a patient with AIP mutation with excess growth and eunuchoid proportions.Unusual, previously not described AIP variant with loss of the stop codon.Phenocopy may occur in families with a disease-causing germline mutation. PMID- 29225776 TI - The sedentary (r)evolution: Have we lost our metabolic flexibility? AB - During the course of evolution, up until the agricultural revolution, environmental fluctuations forced the human species to develop a flexible metabolism in order to adapt its energy needs to various climate, seasonal and vegetation conditions. Metabolic flexibility safeguarded human survival independent of food availability. In modern times, humans switched their primal lifestyle towards a constant availability of energy-dense, yet often nutrient deficient, foods, persistent psycho-emotional stressors and a lack of exercise. As a result, humans progressively gain metabolic disorders, such as the metabolic syndrome, type 2 diabetes, non-alcoholic fatty liver disease, certain types of cancer, cardiovascular disease and Alzheimer's disease, wherever the sedentary lifestyle spreads in the world. For more than 2.5 million years, our capability to store fat for times of food shortage was an outstanding survival advantage. Nowadays, the same survival strategy in a completely altered surrounding is responsible for a constant accumulation of body fat. In this article, we argue that the metabolic disease epidemic is largely based on a deficit in metabolic flexibility. We hypothesize that the modern energetic inflexibility, typically displayed by symptoms of neuroglycopenia, can be reversed by re-cultivating suppressed metabolic programs, which became obsolete in an affluent environment, particularly the ability to easily switch to ketone body and fat oxidation. In a simplified model, the basic metabolic programs of humans' primal hunter-gatherer lifestyle are opposed to the current sedentary lifestyle. Those metabolic programs, which are chronically neglected in modern surroundings, are identified and conclusions for the prevention of chronic metabolic diseases are drawn. PMID- 29472987 TI - Adult female with symptomatic AVPR2-related nephrogenic syndrome of inappropriate antidiuresis (NSIAD). AB - : Activating mutations in AVPR2 are associated with nephrogenic syndrome of inappropriate antidiuresis (NSIAD). NSIAD causes hyponatremia, decreased serum osmolality and clinical symptoms, which may present from birth or in infancy and include hypotonia, irritability, vomiting and/or seizures. Symptoms in later life are often less specific and include malaise, dizziness, confusion, tiredness and headache. NSIAD is a rare X-linked condition, which is associated with a variable phenotype in males, of whom some present in infancy but others do not become symptomatic until adulthood, or occasionally, never. Female carriers may present with episodes of hyponatremia, usually found incidentally. Literature in this field is limited; namely, two clinical reports describing a female proband, both diagnosed in infancy. We describe, for the first time, the case of an adult female proband with NSIAD, who had longstanding associated symptoms of tiredness, headache, temporary memory loss and mood changes as well as hyponatremia and decreased serum osmolality. A water load test demonstrated an inability to dilute urine and gene sequencing confirmed a recurrent activating mutation in AVPR2. The variant was inherited from the proband's mother who had had longstanding episodes of transient asymptomatic hyponatremia. This is the third report of a female proband with NSIAD and is the first female reported who sought medical treatment for chronic symptoms from adulthood. This case acts as a reminder of the importance of considering NSIAD as a diagnosis in females of all ages with unexplained hyponatremia. Learning points: Activating mutations in the AVPR2 gene are associated with the rare X-linked condition nephrogenic syndrome of inappropriate antidiuresis.NSIAD is associated with hyponatremia, decreased serum osmolality and inappropriately increased urinary osmolality. Early clinical symptoms in infancy include hypotonia, irritability, vomiting and/or seizures. Symptoms in later life include malaise, dizziness, confusion, tiredness and headache.NSIAD should be considered in female, as well as male, patients who present with unexplained hyponatremia and decreased serum osmolality. Family history may reveal relevant symptoms or biochemical features in other family members. However, family history may not always be informative due to the variable nature of the condition or if the proband has a de novo pathogenic variant.A water load test with measurement of AVP may be informative in distinguishing NSIAD from SIADH. Measurement of co-peptin levels may be considered, in substitution for direct measurement of AVP.Patients with NSIAD should be counseled about appropriate daily fluid volume intake. Potential episodes of fluid overload should be avoided. PMID- 29472988 TI - Mineralocorticoid hypertension and hypokalaemia induced by posaconazole. AB - : We describe severe hypokalaemia and hypertension due to a mineralocorticoid effect in a patient with myelodysplastic syndrome taking posaconazole as antifungal prophylaxis. Two distinct mechanisms due to posaconazole are identified: inhibition of 11beta hydroxylase leading to the accumulation of the mineralocorticoid hormone 11-deoxycorticosterone (DOC) and secondly, inhibition of 11beta hydroxysteroid dehydrogenase type 2 (11betaHSD2), as demonstrated by an elevated serum cortisol-to-cortisone ratio. The effects were ameliorated by spironolactone. We also suggest that posaconazole may cause cortisol insufficiency. Patients taking posaconazole should therefore be monitored for hypokalaemia, hypertension and symptoms of hypocortisolaemia, at the onset of treatment and on a monthly basis. Treatment with mineralocorticoid antagonists (spironolactone or eplerenone), supplementation of glucocorticoids (e.g. hydrocortisone) or dose reduction or cessation of posaconazole should all be considered as management strategies. Learning points: Combined hypertension and hypokalaemia are suggestive of mineralocorticoid excess; further investigation is appropriate.If serum aldosterone is suppressed, then further investigation to assess for an alternative mineralocorticoid is appropriate, potentially using urine steroid profiling and/or serum steroid panelling.Posaconazole can cause both hypokalaemia and hypertension, and we propose that this is due to two mechanisms - both 11beta hydroxylase inhibition and 11beta HSD2 inhibition.Posaconazole treatment may lead to cortisol insufficiency, which may require treatment; however, in this clinical case, the effect was mild.First-line treatment of this presentation would likely be use of a mineralocorticoid antagonist.Patients taking posaconazole should be monitored for hypertension and hypokalaemia on initiation and monthly thereafter.

AB - Heart failure is a complex disease with poor outcome. This complexity may prevent care providers from covering all aspects of care. This could not only be relevant for individual patient care, but also for care organisation. Disease management programmes applying a multidisciplinary approach are recommended to improve heart failure care. However, there is a scarcity of research considering how disease management programme perform, in what form they should be offered, and what care and support patients and care providers would benefit most. Therefore, the Improving kNowledge Transfer to Efficaciously Raise the level of Contemporary Treatment in Heart Failure (INTERACT-in-HF) study aims to explore the current processes of heart failure care and to identify factors that may facilitate and factors that may hamper heart failure care and guideline adherence. Within a cross-sectional mixed method design in three regions of the North-West part of Europe, patients (n = 88) and their care providers (n = 59) were interviewed. Prior to the in-depth interviews, patients were asked to complete three questionnaires: The Dutch Heart Failure Knowledge scale, The European Heart Failure Self-care Behaviour Scale and The global health status and social economic status. In parallel, retrospective data based on records from these (n = 88) and additional patients (n = 82) are reviewed. All interviews were audiotaped and transcribed verbatim for analysis. PMID- 29472990 TI - Differential Methylation of Syncytin-1 and 2 Distinguishes Fetal Growth Restriction from Physiologic Small for Gestational Age. AB - Objective The retroviral genes encoding Syncytin-1 ( SYN1 ) and Syncytin-2 ( SYN2 ) are epigenetically regulated, uniquely expressed in the placenta and critical to placental function. We sought to determine if placental expression and methylation patterns of SYN1 and SYN2 from pregnancies complicated by fetal growth restriction (FGR) differed from physiologic small for gestational age (SGA) and appropriate for gestational age (AGA) controls. Study Design Placental biopsies were obtained from AGA, SGA and FGR neonates delivered at >36 weeks gestation. SGA and FGR were defined as birth weight <10% with FGR additionally requiring abnormal fetal testing. We quantified DNA methylation of SYN1 and SYN2 by EpiTyper and gene expression by RT-qPCR. Results We identified 10 AGA, 9 SGA and 7 FGR placentas. There was decreased methylation in SYN1 and SYN2 in FGR relative to AGA and SGA. When the sum of SYN1 and SYN2 methylation was used for prediction of FGR from SGA, the area under the receiver operator characteristic curve was 0.9048 (0.7602, 1). Conclusion SYN1 and SYN2 methylation marks differ in FGR and SGA. We plan future studies to examine these markers in cell free DNA to determine if these methylation changes could be used as a biomarker for FGR. PMID- 29472991 TI - The axial skeleton of Poposaurus langstoni (Pseudosuchia: Poposauroidea) and its implications for accessory intervertebral articulation evolution in pseudosuchian archosaurs. AB - Dinosaurs and their close relatives grew to sizes larger than any other terrestrial animal in the history of life on Earth, and many enormous dinosaurs (e.g., Diplodocus, Spinosaurus, Tyrannosaurus) have accessory intervertebral articulations that have been suggested to support these large body sizes. Some pseudosuchian archosaurs have been reported to have these articulations as well, but few have been characterized in these taxa because of a lower abundance of complete, three-dimensional pseudosuchian vertebral material in relation to dinosaurs. We describe the axial column of the large (~4-5 m) poposauroid pseudosuchian Poposaurus langstoni from the Upper Triassic of Texas (TMM Locality 31025 of the Otis Chalk localities; Dockum Group, Howard County, TX, USA). P. langstoni was originally named from pelvic girdle elements and vertebrae; here we describe newly discovered and prepared presacral vertebrae and a presacral rib from the original excavation of the holotype in the 1940s. The well-preserved vertebrae have well-defined vertebral laminae and clear hyposphene-hypantrum intervertebral articulations, character states mentioned in pseudosuchians but rarely described. The new material demonstrates variation present in the hyposphene-hypantrum articulation through the vertebral column. We compared these morphologies to other pseudosuchians with and without the hyposphene-hypantrum articulation. Based on these careful comparisons, we provide an explicit definition for the hyposphene-hypantrum articulation applicable across Archosauria. Within Pseudosuchia, we find the hyposphene-hypantrum appeared independently in the clade at least twice, but we also see the loss of these structures in clades that had them ancestrally. Furthermore, we found the presence of large body sizes (femoral lengths >~300 mm) and the presence of the hyposphene-hypantrum is correlated in most non-crocodylomorph pseudosuchian archosaurs with a few exceptions. This result suggests that the presence of the hyposphene-hypantrum is controlled by the increases and decreases in body size and not strictly inheritance. PMID- 29472992 TI - Different intensities of basketball drills affect jump shot accuracy of expert and junior players. AB - Background: In basketball a maximum accuracy at every game intensity is required while shooting. The aim of the present study was to investigate the acute effect of three different drill intensity simulation protocols on jump shot accuracy in expert and junior basketball players. Materials & Methods: Eleven expert players (age 26 +/- 6 yrs, weight 86 +/- 11 kg, height 192 +/- 8 cm) and ten junior players (age 18 +/- 1 yrs, weight 75 +/- 12 kg, height 184 +/- 9 cm) completed three series of twenty jump shots at three different levels of exertion. Counter Movement Jump (CMJ) height was also measured after each series of jump shots. Exertion's intensity was induced manipulating the basketball drills. Heart rate was measured for the whole duration of the tests while the rating of perceived exertion (RPE) was collected at the end of each series of shots. Results: Heart rate and rating of perceived exertion (RPE) were statistically different in the three conditions for both expert and junior players. CMJ height remained almost unchanged in both groups. Jump shot accuracy decreased with increasing drills intensity both in experts and junior players. Expert players showed higher accuracy than junior players for all the three levels of exertion (83% vs 64%, p < 0.001; 75% vs 57%, p < 0.05; 76% vs 60%, p < 0.01). Moreover, for the most demanding level of exertion, experts showed a higher accuracy in the last ten shots compared to the first ten shots (82% vs 70%, p < 0.05). Discussion: Experts coped better with the different exertion's intensities, thus maintaining a higher level of performance. The introduction of technical short bouts of high-intensity sport-specific exercises into skill sessions should be proposed to improve jump shot accuracy during matches. PMID- 29472993 TI - Life histories predict genetic diversity and population structure within three species of octopus targeted by small-scale fisheries in Northwest Mexico. AB - The fishery for octopus in Northwest Mexico has increased to over 2,000 tons annually, but to date the specific composition of the catch has been ignored. With at least three main species targeted by artisanal fisheries in the region with distinct life histories, the lack of basic biological information about the distribution, metapopulation size and structure of each species could impede effective fisheries management to avoid overexploitation. We tested if different life histories of three species of octopus could help predict observed patterns of genetic diversity, population dynamics, structure and connectivity and how this information could be relevant to the sustainable management of the fishery. We sequenced two mitochondrial genes and genotyped seven nuclear microsatellite loci to identify the distribution of each species in 20 locations from the Gulf of California and the west coast of the Baja California peninsula. We tested five hypotheses derived from population genetic theory based on differences in the fecundity and dispersal potential for each species. We discovered that Octopus bimaculoides with low fecundity and direct development (without a planktonic phase) had lower average effective population size and genetic diversity, but higher levels of kinship, population structure, and richness of private alleles, than the other two species. These features indicated limited dispersal and high local recruitment. In contrast, O. bimaculatus and O. hubbsorum with higher fecundity and planktonic phase as paralarvae had higher effective population size and genetic diversity, and overall lower kinship and population structure than O. bimaculoides. These observations supported higher levels of gene flow over a larger geographical scale. O. bimaculatus with the longest planktonic paralarval duration and therefore larger dispersal potential had differences in the calculated parameters possibly associated with increased connectivity. We propose O. bimaculoides is more susceptible to over exploitation of small, isolated populations and could have longer recovery times than the other two species. This species may benefit from distinct fishery management within each local population. O. bimaculatus and O. hubbsorum may benefit from fishery management that takes into account metapopulation structure over larger geographic scales and the directionality and magnitude of larval dispersal driven by ocean currents and population connectivity among individuals of each locality. The distribution of each species and variations in their reproductive phenology is also important to consider when establishing marine reserves or seasonal fishing closures. PMID- 29472994 TI - Seroprevalence of hepatitis B virus in Taiwan 30 years after the commencement of the national vaccination program. AB - Background: In this study, the long-term efficacy of hepatitis B virus (HBV) vaccination was assessed using seroprevalence and an age-period-cohort (APC) model of HBV seromarkers among university entrants 30 years after the introduction of the national neonatal HBV vaccination program in Taiwan. Methods: In total, data of 17,611 university entrants who underwent university entrance health examinations between 2005 and 2016 were included. The seroprevalence of the HBV surface antigen (HBsAg) and the levels of the antibody against the HBV surface antigen (anti-HBs) in each year group and sex were calculated. The levels of the antibody against the HBV core antigen were examined only for 2012 and 2016. The APC model was used to analyze the HBV carrier rates. Results: The chronic HBV infection (HBsAg positivity) rate decreased from 9.7% in university students born before June 1974 to <1.0% in students born after 1992. The prevalence of anti-HBs positivity declined, particularly between the 1984-1988 cohort (78.2%-53.2%) and the 1990-1994 cohort (60.6%-44.4%). Our APC model revealed that the chronic HBV carrier rate among the student population was affected significantly by age, period, and cohort (P < 0.001). Conclusions: HBV vaccination is one of the most effective strategies for preventing HBV infection. However, for complete eradication of HBV infection, the development of strategies that detect vaccination failure more effectively than current strategies do and early implementation of appropriate treatments are both necessary. PMID- 29472995 TI - Postnatal depression is associated with detrimental life-long and multi generational impacts on relationship quality. AB - Postnatal depression (PND) is known to be associated with a range of detrimental child and adolescent outcomes, resulting from its disruptive impact on mother child relationship quality. However, until now little has been known about the impact of PND on the longer-term relationships between mothers and their children, and any intergenerational effects this may have. Mother-child relationship quality is of interest from an evolutionary perspective as it plays a role in the accrual of offspring embodied capital, thus affecting offspring quality and offspring's capacity to subsequently invest in their own children. Relationships with offspring also mediate grandparent-grandchild relations; if PND negatively affects long-term mother-offspring relationship quality, it is also likely to negatively affect grandmaternal investment via reduced grandmother grandchild relationship quality. Here, we use responses to a retrospective questionnaire study of postmenopausal women, largely from the UK and US, to assess the impact of PND occurring in generation 1 on mother-child relationship quality across the life course of the child (generation 2) with whom it was associated, and also on the relationship quality with grandchildren (generation 3) from that child. Average mother-child relationship quality was lower when the child's birth was associated with PND. Multi-level regression modelling found that mother-child relationship quality decreased as PND symptom severity increased after controlling for individual effects and a variety of other factors known to influence relationship quality (individual mothers n = 296, mother-child dyads n = 646). Additionally, intergenerational relationships appear to be affected, with PND negatively associated with grandmother-grandchild relations (individual grandmothers n = 125, relations with grandchildren from n = 197 grandmother-parent dyads). That PND has long-term detrimental consequences for mother-child relationships, well beyond adolescence, highlights the need for investment in strategies to prevent PND and its cascade of negative multigenerational effects. PMID- 29472996 TI - Metagenomic analysis of orange colored protrusions from the muscle of Queen Conch Lobatus gigas (Linnaeus, 1758). AB - The endangered marine gastropod, Lobatus gigas, is an important fishery resource in the Caribbean region. Microbiological and parasitological research of this species have been poorly addressed despite its role in ecological fitness, conservation status and prevention of potential pathogenic infections. This study identified taxonomic groups associated with orange colored protrusions in the muscle of queen conchs using histological analysis, 454 pyrosequencing, and a combination of PCR amplification and automated Sanger sequencing. The molecular approaches indicate that the etiological agent of the muscle protrusions is a parasite belonging to the subclass Digenea. Additionally, the scope of the molecular technique allowed the detection of bacterial and fungi clades in the assignment analysis. This is the first evidence of a digenean infection in the muscle of this valuable Caribbean resource. PMID- 29472997 TI - A new Python library to analyse skeleton images confirms malaria parasite remodelling of the red blood cell membrane skeleton. AB - We present Skan (Skeleton analysis), a Python library for the analysis of the skeleton structures of objects. It was inspired by the "analyse skeletons" plugin for the Fiji image analysis software, but its extensive Application Programming Interface (API) allows users to examine and manipulate any intermediate data structures produced during the analysis. Further, its use of common Python data structures such as SciPy sparse matrices and pandas data frames opens the results to analysis within the extensive ecosystem of scientific libraries available in Python. We demonstrate the validity of Skan's measurements by comparing its output to the established Analyze Skeletons Fiji plugin, and, with a new scanning electron microscopy (SEM)-based method, we confirm that the malaria parasite Plasmodium falciparum remodels the host red blood cell cytoskeleton, increasing the average distance between spectrin-actin junctions. PMID- 29472998 TI - Vector competence of selected North American Anopheles and Culex mosquitoes for Zika virus. AB - Zika virus (ZIKV) is a vector-borne flavivirus that has caused recent outbreaks associated with serious disease in infants and newborns in the Americas. Aedes mosquitoes are the primary vectors for ZIKV, but little is known about the diversity of mosquitoes that can transmit ZIKV in North America. We chose three abundant North American mosquito species (Anopheles freeborni, Anopheles quadrimaculatus, and Culex tarsalis) and one known vector species (Aedes aegypti), fed them blood meals supplemented with a recent outbreak ZIKV strain, and tested bodies, legs, and saliva for infectious ZIKV. ZIKV was able to infect, disseminate, and be transmitted by Aedes aegypti. However, Anopheles freeborni, Anopheles quadrimaculatus, and Culex tarsalis were unable to be infected. We conclude that these species are unlikely to be involved in ZIKV transmission in North America. However, we should continue to examine the ability for other mosquito species to potentially act as ZIKV vectors in North America. PMID- 29472999 TI - Ontogeny of long-range vocalizations in a Neotropical fossorial rodent: the Anillaco Tuco-Tuco (Ctenomys sp.). AB - Tuco-tucos (Ctenomys spp.) are subterranean rodents that produce territorial, high intensity long-range vocalizations (LRVs) of broadband and low frequency that are essential for long-distance communication between individuals in different tunnel systems. Despite their importance, the development of LRVs remains poorly understood. In adult Anillaco Tuco-Tucos (Ctenomys sp.) the LRV is composed by two types of syllables (series and individual notes) that are repeated a variable number of times. We studied the development of the LRVs in eight juveniles of the Anillaco Tuco-Tuco ranging from 14-28 to 104-118 days after birth. We (1) tested whether the syllables followed any of three alternative developmental modes (retention of juvenile vocalizations, modification of juvenile precursors or de novo appearance in adults), (2) evaluated the development of structural and acoustic features of syllables, and (3) tested the prediction that juveniles should produce a greater proportion of atypical series in precursors of the LRV than adults, due to lack maturation and/or precise coupling of neuromuscular and anatomical structures. The LRV of the Anillaco Tuco-Tuco exhibited a mixed developmental mode: while series developed from juvenile precursors whose acoustic features gradually approached those of adults, individual notes appeared later in the ontogeny and de novo with acoustic features indistinguishable from those of adults. The number of series per vocalization increased through development and varied from one to 25 in juvenile males and from one to six in juvenile females. The structure of the most common series type (triad) did not exhibit ontogenetic changes and was present as such at the onset of the emission of vocalizations. On the contrary, acoustic features of juvenile triad notes changed with age in both sexes (duration 90% increased through development, while bandwidth 90% and peak frequency decreased). Furthermore, juveniles emitted a higher proportion of atypical series than adults (7.4% vs. 0.3%), as expected in the development of any complex behavior that requires practice to be mastered. The maturation of the LRV occurred well before the sexual maturation, presumably due to the protracted time needed to acquire or build a burrow system long before mating is possible. We propose that protracted vocal development is another component in the slow developmental strategy of Ctenomys and subterranean rodents in general. PMID- 29473000 TI - Morphometric analysis of a triple negative breast cancer cell line in hydrogel and monolayer culture environments. AB - Triple negative breast cancer (TNBC) is a belligerent carcinoma that is unresponsive to targeted receptor therapies. Development of new treatment strategies would benefit from an expanded repertoire of in vitro cell culture systems, such as those that support tridimensional growth in the presence of hydrogel scaffolds. To this end, we established protocols for maintenance of the TNBC cell line HCC70 in monolayer culture and in a commercially available basement membrane matrix hydrogel. We evaluated the general morphology of cells grown in both conditions with light microscopy, and examined their subcellular organization using transmission electron microscopy (TEM). Phase contrast and confocal microscopy showed the prevalence of irregularly shaped flattened cells in monolayer cultures, while cells maintained in hydrogel organized into multi layered spheroids. A quantitative ultrastructural analysis comparing cells from the two culture conditions revealed that cells that formed spheroids comprised a greater number of mitochondria, autophagic vacuoles and intercellular junctions than their monolayer counterparts, within the equivalent area of sampled tissue. These observations suggest that triple negative breast cancer cells in culture can alter their organelle content, as well as their morphology, in response to their microenvironment. Methods presented here may be useful for those who intend to image cell cultures with TEM, and for investigators who seek to implement diverse in vitro models in the search for therapeutic molecular targets for TNBC. PMID- 29473001 TI - Body mass index influences the plasma glucose concentration during iatrogenic hypoglycemia in people with type 2 diabetes mellitus: a cross-sectional study. AB - Background: Hypoglycemia occurs in an appreciable number of individuals with type 2 diabetes mellitus (T2DM) who are receiving glycemic therapy. Iatrogenic hypoglycemia induces not only complications but also a substantial medical expense. Intervention for relevant risk factors may help avert severe hypoglycemia and enhance quality of life in at-risk individuals. This study investigates the relationship between body mass index (BMI) and plasma glucose concentration during iatrogenic hypoglycemia in people with T2DM. Methods: Enrollment criteria were people above 20 years of age, with existing diagnosis of T2DM, a documented plasma glucose level <=70 mg/dL, and acute cognitive impairment requiring hospitalization. Participants were classified into two groups according to their BMI. Specifically, lower BMI subgroup denotes individuals whose BMI fall within lower half of the study population, and vice versa. Plasma glucose concentration, length of hospital stay, and serum electrolyte level at hospitalization were compared between these BMI subgroups. Moreover, multivariate regression analysis was performed to identify covariates associated with plasma glucose level during iatrogenic hypoglycemia. Results: This study enrolled 107 participants for whom 54 were assigned to a higher BMI subgroup and the remainder to a lower BMI subgroup. People with lower BMI harbored substantially reduced plasma glucose concentration during iatrogenic hypoglycemia compared to those with higher BMI (30.1 +/- 9.6 mg/dL vs. 38.4 +/- 12.3 mg/dL, P < 0.001). Nonetheless, the length of stay (6.2 +/- 4.6 days vs. 5.7 +/- 4.0 days, P = 0.77) and serum potassium level (3.7 +/- 0.9 meq/L vs. 3.9 +/- 0.8 meq/L, P = 0.14) were comparable between subgroups. Multivariate regression analysis identified BMI as a determinant of plasma glucose concentration in diabetic individuals with iatrogenic hypoglycemia (beta coefficient: 0.72, P = 0.008). Discussion: In individuals with T2DM who experience severe iatrogenic hypoglycemia, BMI influences the plasma glucose level at hospitalization. People with lower BMI harbored appreciably reduced plasma glucose concentration relative to their higher BMI counterparts. In lower weight people, therefore, appropriate dosing of antidiabetic medications, frequent self-monitoring of blood glucose level and adequate nutritional support may help avert more severe hypoglycemia. Overall, BMI potentially influences the severity of iatrogenic hypoglycemia in people with T2DM. PMID- 29473003 TI - Optimization of antioxidative peptides from mackerel (Pneumatophorus japonicus) viscera. AB - Mackerel (Pneumatophorus japonicus) viscera contain large amount of protein. We used five proteases to hydrolyze the viscera, and the hydrolysate treated by neutrase exhibited the highest nitrogen recovery (NR). Then we optimized the preparation conditions for mackerel viscera hydrolysate (MVH) by response surface methodology and investigated the antioxidant activity of MVH. The optimal conditions were as follows: enzyme concentration of 1,762.87 U/g, pH of 6.76, temperature of 43.75 degrees C, extraction time of 6.0 h and water/material ratio of 20.37 (v/w), and the maximum NR was 37.84%. Furthermore, the molecular weight distribution of MVH was almost below 3,000 Da determined by TSK G2000 SWXL gel filtration chromatography, and the MVH exhibited good antioxidant activities in various in vitro assays, including DPPH radical, hydroxyl radical and superoxide anion scavenging activities, reducing power and similar effectivelness as butylated hydroxytoluene and Vitamin E to inhibit lipid peroxidation. The results suggested that MVH could be used as a potential source of antioxidant peptide in food industries. PMID- 29473002 TI - Genomic analysis of morphometric traits in bighorn sheep using the Ovine Infinium(r) HD SNP BeadChip. AB - Elucidating the genetic basis of fitness-related traits is a major goal of molecular ecology. Traits subject to sexual selection are particularly interesting, as non-random mate choice should deplete genetic variation and thereby their evolutionary benefits. We examined the genetic basis of three sexually selected morphometric traits in bighorn sheep (Ovis canadensis): horn length, horn base circumference, and body mass. These traits are of specific concern in bighorn sheep as artificial selection through trophy hunting opposes sexual selection. Specifically, horn size determines trophy status and, in most North American jurisdictions, if an individual can be legally harvested. Using between 7,994-9,552 phenotypic measures from the long-term individual-based study at Ram Mountain (Alberta, Canada), we first showed that all three traits are heritable (h2 = 0.15-0.23). We then conducted a genome-wide association study (GWAS) utilizing a set of 3,777 SNPs typed in 76 individuals using the Ovine Infinium(r) HD SNP BeadChip. We found suggestive association for body mass at a single locus (OAR9_91647990). The absence of strong associations with SNPs suggests that the traits are likely polygenic. These results represent a step forward for characterizing the genetic architecture of fitness related traits in sexually dimorphic ungulates. PMID- 29473004 TI - Catchment land use predicts benthic vegetation in small estuaries. AB - Many estuaries are becoming increasingly eutrophic from human activities within their catchments. Nutrient loads often are used to assess risk of eutrophication to estuaries, but such data are expensive and time consuming to obtain. We compared the percent of fertilized land within a catchment, dissolved inorganic nitrogen loads, catchment to estuary area ratio and flushing time as predictors of the proportion of macroalgae to total vegetation within 14 estuaries in south eastern Australia. The percent of fertilized land within the catchment was the best predictor of the proportion of macroalgae within the estuaries studied. There was a transition to a dominance of macroalgae once the proportion of fertilized land in the catchment exceeded 24%, highlighting the sensitivity of estuaries to catchment land use. PMID- 29473005 TI - Identification and expression profile analysis of the sucrose phosphate synthase gene family in Litchi chinensis Sonn. AB - Sucrose phosphate synthase (SPS, EC 2.4.1.14) is a key enzyme that regulates sucrose biosynthesis in plants. SPS is encoded by different gene families which display differential expression patterns and functional divergence. Genome-wide identification and expression analyses of SPS gene families have been performed in Arabidopsis, rice, and sugarcane, but a comprehensive analysis of the SPS gene family in Litchi chinensis Sonn. has not yet been reported. In the current study, four SPS gene (LcSPS1, LcSPS2, LcSPS3, and LcSPS4) were isolated from litchi. The genomic organization analysis indicated the four litchi SPS genes have very similar exon-intron structures. Phylogenetic tree showed LcSPS1-4 were grouped into different SPS families (LcSPS1 and LcSPS2 in A family, LcSPS3 in B family, and LcSPS4 in C family). LcSPS1 and LcSPS4 were strongly expressed in the flowers, while LcSPS3 most expressed in mature leaves. RT-qPCR results showed that LcSPS genes expressed differentially during aril development between cultivars with different hexose/sucrose ratios. A higher level of expression of LcSPS genes was detected in Wuheli, which accumulates higher sucrose in the aril at mature. The tissue- and developmental stage-specific expression of LcSPS1-4 genes uncovered in this study increase our understanding of the important roles played by these genes in litchi fruits. PMID- 29473006 TI - Benthic grazing in a eutrophic river: cascading effects of zoobenthivorous fish mask direct effects of herbivorous fish. AB - Benthic grazing strongly controls periphyton biomass. The question therefore arises whether benthic grazing could be used as a tool to reduce excessive growth of periphyton in nutrient-enriched rivers. Although benthic invertebrate grazers reduce the growth of periphyton, this is highly context dependent. Here we assessed whether the only obligate herbivorous fish in European rivers, the common nase (Chondrostoma nasus L.), is able to reduce periphyton biomass in a eutrophic river. We conducted three consecutive in situ experiments at low, intermediate and high densities of nase in the river using standard tiles on the river bottom naturally covered with periphyton that were accessible to fish and tiles that excluded fish foraging with electric exclosures. The biomass of benthic invertebrate grazers was very low relative to nase. We hypothesised that nase would reduce periphyton biomass on accessible tiles and therefore expected higher periphyton biomass on the exclosure tiles, at least at intermediate and high densities of nase in the river. Contrary to our expectation, the impact of fish grazing was low even at high fish density, as judged by the significantly lower chlorophyll a concentration on exclosure tiles even though the ash-free dry mass on accessible and exclosure tiles did not differ. The lower chlorophyll a concentrations on exclosure tiles might be explained by a higher biomass of invertebrate grazers on the exclosure tiles, which would indicate that the effect of invertebrate grazers was stronger than that of herbivorous fish grazers. The high biomass of invertebrate grazers on exclosure tiles likely arose from the exclusion of zoobenthivorous fish, which occur in the river at high densities. The results of our small-scale experiments suggested that cascading top-down effects of zoobenthivorous fish have a higher impact on periphyton biomass than direct effects of herbivorous nase. PMID- 29473007 TI - High-resolution modeling of thermal thresholds and environmental influences on coral bleaching for local and regional reef management. AB - Coral reefs are one of the world's most threatened ecosystems, with global and local stressors contributing to their decline. Excessive sea-surface temperatures (SSTs) can cause coral bleaching, resulting in coral death and decreases in coral cover. A SST threshold of 1 degrees C over the climatological maximum is widely used to predict coral bleaching. In this study, we refined thermal indices predicting coral bleaching at high-spatial resolution (1 km) by statistically optimizing thermal thresholds, as well as considering other environmental influences on bleaching such as ultraviolet (UV) radiation, water turbidity, and cooling effects. We used a coral bleaching dataset derived from the web-based monitoring system Sango Map Project, at scales appropriate for the local and regional conservation of Japanese coral reefs. We recorded coral bleaching events in the years 2004-2016 in Japan. We revealed the influence of multiple factors on the ability to predict coral bleaching, including selection of thermal indices, statistical optimization of thermal thresholds, quantification of multiple environmental influences, and use of multiple modeling methods (generalized linear models and random forests). After optimization, differences in predictive ability among thermal indices were negligible. Thermal index, UV radiation, water turbidity, and cooling effects were important predictors of the occurrence of coral bleaching. Predictions based on the best model revealed that coral reefs in Japan have experienced recent and widespread bleaching. A practical method to reduce bleaching frequency by screening UV radiation was also demonstrated in this paper. PMID- 29473008 TI - Codominant grasses differ in gene expression under experimental climate extremes in native tallgrass prairie. AB - Extremes in climate, such as heat waves and drought, are expected to become more frequent and intense with forecasted climate change. Plant species will almost certainly differ in their responses to these stressors. We experimentally imposed a heat wave and drought in the tallgrass prairie ecosystem near Manhattan, Kansas, USA to assess transcriptional responses of two ecologically important C4 grass species, Andropogon gerardii and Sorghastrum nutans. Based on previous research, we expected that S. nutans would regulate more genes, particularly those related to stress response, under high heat and drought. Across all treatments, S. nutans showed greater expression of negative regulatory and catabolism genes while A. gerardii upregulated cellular and protein metabolism. As predicted, S. nutans showed greater sensitivity to water stress, particularly with downregulation of non-coding RNAs and upregulation of water stress and catabolism genes. A. gerardii was less sensitive to drought, although A. gerardii tended to respond with upregulation in response to drought versus S. nutans which downregulated more genes under drier conditions. Surprisingly, A. gerardii only showed minimal gene expression response to increased temperature, while S. nutans showed no response. Gene functional annotation suggested that these two species may respond to stress via different mechanisms. Specifically, A. gerardii tends to maintain molecular function while S. nutans prioritizes avoidance. Sorghastrum nutans may strategize abscisic acid response and catabolism to respond rapidly to stress. These results have important implications for success of these two important grass species under a more variable and extreme climate forecast for the future. PMID- 29473009 TI - COREMIC: a web-tool to search for a niche associated CORE MICrobiome. AB - Microbial diversity on earth is extraordinary, and soils alone harbor thousands of species per gram of soil. Understanding how this diversity is sorted and selected into habitat niches is a major focus of ecology and biotechnology, but remains only vaguely understood. A systems-biology approach was used to mine information from databases to show how it can be used to answer questions related to the core microbiome of habitat-microbe relationships. By making use of the burgeoning growth of information from databases, our tool "COREMIC" meets a great need in the search for understanding niche partitioning and habitat-function relationships. The work is unique, furthermore, because it provides a user friendly statistically robust web-tool (http://coremic2.appspot.com or http://core-mic.com), developed using Google App Engine, to help in the process of database mining to identify the "core microbiome" associated with a given habitat. A case study is presented using data from 31 switchgrass rhizosphere community habitats across a diverse set of soil and sampling environments. The methodology utilizes an outgroup of 28 non-switchgrass (other grasses and forbs) to identify a core switchgrass microbiome. Even across a diverse set of soils (five environments), and conservative statistical criteria (presence in more than 90% samples and FDR q-val <0.05% for Fisher's exact test) a core set of bacteria associated with switchgrass was observed. These included, among others, closely related taxa from Lysobacter spp., Mesorhizobium spp, and Chitinophagaceae. These bacteria have been shown to have functions related to the production of bacterial and fungal antibiotics and plant growth promotion. COREMIC can be used as a hypothesis generating or confirmatory tool that shows great potential for identifying taxa that may be important to the functioning of a habitat (e.g. host plant). The case study, in conclusion, shows that COREMIC can identify key habitat-specific microbes across diverse samples, using currently available databases and a unique freely available software.

AB - Expanded access is a regulatory mechanism by which an investigational drug can be made available outside of a clinical trial to treat patients with serious or life threatening conditions for which there are no satisfactory treatment options. An expanded access program (EAP) is the formal plan under which preapproval access to an investigational drug can be provided to a group of patients. Although an EAP is a regulated program, the decision to authorize an EAP is the responsibility of the biopharmaceutical sponsor. Because of the significant impact an EAP can have on current patients, drug development, and future patients, we propose that a sponsor's decision must be based not only on regulatory criteria but also on ethical and practical considerations regarding implementation of an EAP. Such an approach will help ensure that decisions and plans uphold ethical precepts such as fairness, promoting good, and minimizing risk of harm. PMID- 29473011 TI - Use of 3D Navigation in Subaxial Cervical Spine Lateral Mass Screw Insertion. AB - Objective Cervical spine can be stabilized by different techniques. One of the common techniques used is the lateral mass screws (LMSs), which can be inserted either by freehand techniques or three-dimensional (3D) navigation system. The purpose of this study is to evaluate the difference between the 3D navigation system and the freehand technique for cervical spine LMS placement in terms of complications. Including intraoperative complications (vertebral artery injury [VAI], nerve root injury [NRI], spinal cord injury [SCI], lateral mass fracture [LMF]) and postoperative complications (screw malposition, screw complications). Methods Patients who had LMS fixation for their subaxial cervical spine from January 2014 to April 2015 at the Ottawa Hospital were included. A total of 284 subaxial cervical LMS were inserted in 40 consecutive patients. Surgical indications were cervical myelopathy and fractures. The screws' size was 3.5 mm in diameter and 8 to 16 mm in length. During the insertion of the subaxial cervical LMS, the 3D navigation system was used for 20 patients, and the freehand technique was used for the remaining 20 patients. We reviewed the charts, X-rays, computed tomography (CT) scans, and follow-up notes for all the patients pre- and postoperatively. Results Postoperative assessment showed that the incidence of VAI, SCI, and NRI were the same between the two groups. The CT scan analysis showed that the screw breakage, screw pull-outs, and screw loosening were the same between the two groups. LMF was less in the 3D navigation group but statistically insignificant. Screw malposition was less in the 3D navigation group compared with the freehand group and was statistically significant. The hospital stay, operative time, and blood loss were statistically insignificant between the two groups. Conclusions The use of CT-based navigation in LMS insertion decreased the rate of screw malpositions as compared with the freehand technique. Further investigations and trials will determine the effect of malpositions on the c-spine biomechanics. The use of navigation in LMS insertion did not show a significant difference in VAI, LMF, SCI, or NRI as compared with the freehand technique. PMID- 29473012 TI - Nuss Procedure for a Patient with Negative Haller Index. AB - Introduction Minimally invasive repair for pectus excavatum (MIRPE) is controversial in extremely severe cases of pectus excavatum (PE) and an open repair is usually favored. Our aim is to describe a case of a patient with an extremely severe PE that underwent a minimally invasive approach. Case report An 8-year-old girl with severe sternum depression was assessed. She had a history of exercise intolerance, nocturnal dyspnea, fatigue, and shortness of breath. Chest computed tomography showed that sternum depression was posterior to the anterior vertebral column; therefore, Haller and correction index could not be measured. Spirometry indicated an obstructive ventilation pattern (forced expiratory volume in 1 second = 74.4%), and echocardiogram revealed a dilated inferior vena cava, mitral valve prolapse with normal ventricular function. After multidisciplinary committee evaluation, a MIRPE approach was performed. All symptoms had disappeared at the 3-month postoperative follow-up; the desired sternum shape was achieved and normalization of cardiopulmonary function was observed. The Nuss bars were removed after a 2-year period. After 18-month follow-up, the patient can carry out normal exercise and is content with the cosmetic result. Conclusion Nuss procedure is feasible in our 8-year-old patient. In this case, both the Haller and correction index were not useful to assess the severity of PE. Therefore, under these circumstances, other radiologic parameters have to be taken into consideration for patient evaluation. PMID- 29473013 TI - High-Risk Repair of Traumatic Mitral Valve Rupture in the Setting of Polytrauma. AB - Background The rare complication of mitral valve rupture from blunt trauma is certainly not at the top of the differential of shock. Case Description We report the case of a 56-year-old woman who sustained numerous injuries after a 30 m fall with cardiogenic shock secondary to mitral valve rupture causing severe mitral valve regurgitation. Management included successful primary leaflet repair, annuloplasty, and single vessel coronary artery bypass. Conclusion Valvular repair in the setting of polytrauma is a complex decision that requires careful balance of risks and benefits relative to patient stability. PMID- 29473014 TI - Angiosarcoma of the Left Atrium: A Case Report. AB - Background Primary cardiac tumors are rare, and many diagnosed tumors are benign with an incidence of 0.001% to 0.03%. The primary angiosarcoma is one of the malignant entities. Discussion We discuss a case report of a 76-year-old male who underwent a preoperative diagnosis for an upcoming shoulder operation when his cardiologist diagnosed a large cardiac tumor. The patient was referred to our department where he received further diagnostics. The transesophageal echocardiography and the cardiac-magnetic resonance imaging showed a massive tumor with a dimension of 8.6 * 5.6 cm with no signs of malignity. Method The operation was performed by standard median sternotomy. The tumor was adherent to the septum and the left atrium, and we were able to remove the specimen in toto. Pathological examinations showed an angiosarcoma with neovascularization and core expression of ERG+ and cytoplasmic expression of CD31+/CD34+, due to the size of the mass. The resection of primary cardiac tumors is mostly the therapy of choice, but in this case concerning an angiosarcoma the prognosis is poor, considering that the angiosarcoma responds very badly to chemotherapy and radiotherapy. PMID- 29473015 TI - Molecular analysis of integrons and antimicrobial resistance profile in Shigella spp. isolated from acute pediatric diarrhea patients. AB - Introduction:Shigella spp. is a growing global health concern due to increasing multiple drug resistance, commonly resulting in therapeutic failure. Integrons are gene expression systems run by integrase genes. The aims of this study were detection of class I, II and III integrons and assessment of antimicrobial resistance in Shigella spp. isolated from acute pediatric diarrhea patients. Materials and methods: From January to December 2015, 16 Shigella spp. were isolated from 310 non-duplicative diarrheal stool samples in Children's Medical Center, Tehran, Iran. The isolates were analyzed for their antibiotic susceptibility using CLSI guidelines M100-S14. Multiplex PCR was used for amplification of I, II and III integron-associated integrase (intl) genes. Results: Of 310 stool samples, 16 (5.2%) were positive for Shigella spp., in 7 of them S. sonnei and in 9 of them S. flexneri were identified. Results of the antimicrobial susceptibility test showed that 6.2%, 50%, 31.2%, 6.2%, 81.2%, 56.2% and 31.2% of the isolates were resistant to gentamicin, chloramphenicol, nalidixic acid, ciprofloxacin, tetracycline, ampicillin and trimethoprim sulfamethoxazole, respectively. Multiplex PCR results revealed that 6.2% (1/16), 31.2% (5/16), 50% (8/16) of Shigella isolates carried intlI, intlII and both intlI/intllI genes. No class 3 integrons were detected. Discussion: In this study, multidrug resistance was seen in Shigella isolates similar to that in isolates from other geographical areas. This is possible due to inappropriate use of antimicrobials. Furthermore, prevalence of multidrug resistance was significantly linked to the presence of integrin genes. Conclusion: A class 2 integron plays a role in presence of multidrug resistance in Shigella spp. It is vital to prevent the spread of antibiotic resistance through continuous monitoring.

PMID- 29473017 TI - Roadmap to Wellness: Exploring Live Customized Music at the Bedside for Hospitalized Children. AB - Background: Randomized trials on clinical outcomes of music are conflicting, with few performed in the postoperative pediatric population. We aimed to determine if there was a benefit of a live, customized bedside music delivery program (MyMusicRx(r)) for children hospitalized after pediatric surgery. We present our perspective on the utility of music medicine, review others' work in this area, and discuss future directions. Methods: All admitted postsurgical patients aged between 5 and 18 years were considered. One live, customized music session was delivered by a MyMusicRx(r) music specialist to intervention participants, and compared with matched controls who did not receive music intervention. Pain, cumulative analgesia dosage, and vital signs within 12 h after unit arrival were compared between groups. Results: Thirty-two participants (16 intervention, 16 controls; 8:8 females:males per group) were enrolled. No differences in age, surgery length, or duration of music intervention were found between groups. No differences in pain scores (p = 0.73), heart rate (p = 0.82), respirations (p = 84), narcotic (p = 0.92) or non-narcotic medication usage (p = 0.88, 0.86, 0.95; ibuprofen, acetaminophen, and ketorolac, respectively), or time to first narcotic dose (p = 0.64) were found. Conclusion: A single music intervention in the acute postoperative period did not appear to be adequate to augment traditional methods of pain and hemodynamic control. Prior studies have similar outcome measures but conflicting results. We did not evaluate psychological well-being, patient engagement, or family perception in this pilot study. Future directions include developing and validating a tool that explores the observable impact of music medicine on children's emotions and behaviors. PMID- 29473018 TI - A Global Analysis of Kinase Function in Candida albicans Hyphal Morphogenesis Reveals a Role for the Endocytosis Regulator Akl1. AB - The human pathogenic fungus Candida albicans can switch between yeast and hyphal morphologies as a function of environmental conditions and cellular physiology. The yeast-to-hyphae morphogenetic switch is activated by well-established, kinase based signal transduction pathways that are induced by extracellular stimuli. In order to identify possible inhibitory pathways of the yeast-to-hyphae transition, we interrogated a collection of C. albicans protein kinases and phosphatases ectopically expressed under the regulation of the TETon promoter. Proportionately more phosphatases than kinases were identified that inhibited hyphal morphogenesis, consistent with the known role of protein phosphorylation in hyphal induction. Among the kinases, we identified AKL1 as a gene that significantly suppressed hyphal morphogenesis in serum. Akl1 specifically affected hyphal elongation rather than initiation: overexpression of AKL1 repressed hyphal growth, and deletion of AKL1 resulted in acceleration of the rate of hyphal elongation. Akl1 suppressed fluid-phase endocytosis, probably via Pan1, a putative clathrin-mediated endocytosis scaffolding protein. In the absence of Akl1, the Pan1 patches were delocalized from the sub-apical region, and fluid-phase endocytosis was intensified. These results underscore the requirement of an active endocytic pathway for hyphal morphogenesis. Furthermore, these results suggest that under standard conditions, endocytosis is rate limiting for hyphal elongation. PMID- 29473019 TI - Utilization of Different Omic Approaches to Unravel Stress Response Mechanisms in the Parasite Entamoeba histolytica. AB - During its life cycle, the unicellular parasite Entamoeba histolytica is challenged by a wide variety of environmental stresses, such as fluctuation in glucose concentration, changes in gut microbiota composition, and the release of oxidative and nitrosative species from neutrophils and macrophages. The best mode of survival for this parasite is to continuously adapt itself to the dynamic environment of the host. Our ability to study the stress-induced responses and adaptive mechanisms of this parasite has been transformed through the development of genomics, proteomics or metabolomics (omics sciences). These studies provide insights into different facets of the parasite's behavior in the host. However, there is a dire need for multi-omics data integration to better understand its pathogenic nature, ultimately paving the way to identify new chemotherapeutic targets against amebiasis. This review provides an integration of the most relevant omics information on the mechanisms that are used by E. histolytica to resist environmental stresses. PMID- 29473020 TI - Functional Analysis of the Chaperone-Usher Fimbrial Gene Clusters of Salmonella enterica serovar Typhi. AB - The human-specific pathogen Salmonella enterica serovar Typhi causes typhoid, a major public health issue in developing countries. Several aspects of its pathogenesis are still poorly understood. S. Typhi possesses 14 fimbrial gene clusters including 12 chaperone-usher fimbriae (stg, sth, bcf, fim, saf, sef, sta, stb, stc, std, ste, and tcf). These fimbriae are weakly expressed in laboratory conditions and only a few are actually characterized. In this study, expression of all S. Typhi chaperone-usher fimbriae and their potential roles in pathogenesis such as interaction with host cells, motility, or biofilm formation were assessed. All S. Typhi fimbriae were better expressed in minimal broth. Each system was overexpressed and only the fimbrial gene clusters without pseudogenes demonstrated a putative major subunits of about 17 kDa on SDS-PAGE. Six of these (Fim, Saf, Sta, Stb, Std, and Tcf) also show extracellular structure by electron microscopy. The impact of fimbrial deletion in a wild-type strain or addition of each individual fimbrial system to an S. Typhi afimbrial strain were tested for interactions with host cells, biofilm formation and motility. Several fimbriae modified bacterial interactions with human cells (THP-1 and INT-407) and biofilm formation. However, only Fim fimbriae had a deleterious effect on motility when overexpressed. Overall, chaperone-usher fimbriae seem to be an important part of the balance between the different steps (motility, adhesion, host invasion and persistence) of S. Typhi pathogenesis. PMID- 29473022 TI - Intranasal Immunization with DnaK Protein Induces Protective Mucosal Immunity against Tuberculosis in CD4-Depleted Mice. AB - Mycobacterium tuberculosis (Mtb) remains a global health challenge due to the limited efficacy of the Mtb vaccine in current use, Bacillus Calmette-Guerin (BCG). To date, there is no available vaccine for immunocompromised individuals. Thus, there is an urgent need to develop a new vaccine candidate which can induce mucosal immunity in hosts with different immune statuses. DnaK (HSP70) has been shown to induce protective immunity against Mtb infection when administered by DNA vaccine; however, the protection is inferior to that induced by the BCG vaccine. In our study, we vaccinated C57BL/6J mice with DnaK protein alone. Subcutaneous or intranasal vaccination with DnaK generated IFNgamma-secreting CD4+ T cells in the spleen, but only intranasal vaccination generated IL-17 releasing CD4+ T cells in the lungs, even when circulating CD4+ T cells were diminished. Furthermore, intranasal vaccination with DnaK generated tissue resident CD4+ T cells in the lungs. Vaccination with DnaK alone resulted in protective immunity comparable to BCG vaccination against tuberculosis in mice. Our results demonstrate that intranasal vaccination with DnaK can generate mucosal immunity in immunocompromised or immunocompetent mice and DnaK vaccination can generate protection against Mtb similar to BCG, underscoring its potential utility as an Mtb vaccine candidate in humans. PMID- 29473021 TI - Clostridioides difficile Biology: Sporulation, Germination, and Corresponding Therapies for C. difficile Infection. AB - Clostridioides difficile is a Gram-positive, spore-forming, toxin-producing anaerobe, and an important nosocomial pathogen. Due to the strictly anaerobic nature of the vegetative form, spores are the main morphotype of infection and transmission of the disease. Spore formation and their subsequent germination play critical roles in C. difficile infection (CDI) progress. Under suitable conditions, C. difficile spores will germinate and outgrow to produce the pathogenic vegetative form. During CDI, C. difficile produces toxins (TcdA and TcdB) that are required to initiate the disease. Meanwhile, it also produces spores that are responsible for the persistence and recurrence of C. difficile in patients. Recent studies have shed light on the regulatory mechanisms of C. difficile sporulation and germination. This review is to summarize recent advances on the regulation of sporulation/germination in C. difficile and the corresponding therapeutic strategies that are aimed at these important processes. PMID- 29473023 TI - Basic Characterization of Natural Transformation in a Highly Transformable Haemophilus parasuis Strain SC1401. AB - Haemophilus parasuis causes Glasser's disease and pneumonia, incurring serious economic losses in the porcine industry. In this study, natural competence was investigated in H. parasuis. We found competence genes in H. parasuis homologous to ones in Haemophilus influenzae and a high consensus battery of Sxy-dependent cyclic AMP (cAMP) receptor protein (CRP-S) regulons using bioinformatics. High rates of natural competence were found from the onset of stationary-phase growth condition to mid-stationary phase (OD600 from 0.29 to 1.735); this rapidly dropped off as cells reached mid-stationary phase (OD600 from 1.735 to 1.625). As a whole, bacteria cultured in liquid media were observed to have lower competence levels than those grown on solid media plates. We also revealed that natural transformation in this species is stable after 200 passages and is largely dependent on DNA concentration. Transformation competition experiments showed that heterogeneous DNA cannot outcompete intraspecific natural transformation, suggesting an endogenous uptake sequence or other molecular markers may be important in differentiating heterogeneous DNA. We performed qRT-PCR targeting multiple putative competence genes in an effort to compare bacteria pre-cultured in TSB++ vs. TSA++ and SC1401 vs. SH0165 to determine expression profiles of the homologs of competence-genes in H. influenzae. Taken together, this study is the first to investigate natural transformation in H. parasuis based on a highly naturally transformable strain SC1401. PMID- 29473025 TI - Dynamics and Control of Flagella Assembly in Salmonella typhimurium. AB - The food-borne pathogen Salmonella typhimurium is a common cause of infections and diseases in a wide range of hosts. One of the major virulence factors associated to the infection process is flagella, which helps the bacterium swim to its preferred site of infection inside the host, the M-cells (Microfold cells) lining the lumen of the small intestine. The expression of flagellar genes is controlled by an intricate regulatory network. In this work, we investigate two aspects of flagella regulation and assembly: (a) distribution of the number of flagella in an isogenic population of bacteria and (b) dynamics of gene expression post cell division. More precisely, in a population of bacteria, we note a normal distribution of number of flagella assembled per cell. How is this distribution controlled, and what are the key regulators in the network which help the cell achieve this? In the second question, we explore the role of protein secretion in dictating gene expression dynamics post cell-division (when the number of hook basal bodies on the cell surface is reduced by a factor of two). We develop a mathematical model and perform stochastic simulations to address these questions. Simulations of the model predict that two accessory regulators of flagella gene expression, FliZ and FliT, have significant roles in maintaining population level distribution of flagella. In addition, FliT and FlgM were predicted to control the level and temporal order of flagellar gene expression when the cell adapts to post cell division consequences. Further, the model predicts that, the FliZ and FliT dependent feedback loops function under certain thresholds, alterations in which can substantially affect kinetics of flagellar genes. Thus, based on our results we propose that, the proteins FlgM, FliZ, and FliT, thought to have accessory roles in regulation of flagella, likely play a critical role controlling gene expression during cell division, and frequency distribution of flagella. PMID- 29473026 TI - Mitigating Latent Threats Identified through an Embedded In Situ Simulation Program and Their Comparison to Patient Safety Incidents: A Retrospective Review. AB - Objective: To assess the impact of service improvements implemented because of latent threats (LTs) detected during in situ simulation. Design: Retrospective review from April 2008 to April 2015. Setting: Paediatric Intensive Care Unit in a specialist tertiary hospital. Intervention: Service improvements from LTs detection during in situ simulation. Action plans from patient safety incidents (PSIs). Main outcome measures: The quantity, category, and subsequent service improvements for LTs. The quantity, category, and subsequent action plans for PSIs. Similarities between PSIs and LTs before and after service improvements. Results: 201 Simulated inter-professional team training courses with 1,144 inter professional participants. 44 LTs were identified (1 LT per 4.6 courses). Incident severity varied: 18 (41%) with the potential to cause harm, 20 (46%) that would have caused minimal harm, and 6 (13%) that would have caused significant temporary harm. Category analysis revealed the majority of LTs were resources (36%) and education and training (27%). The remainder consisted of equipment (11%), organizational and strategic (7%), work and environment (7%), medication (7%), and systems and protocols (5%). 43 service improvements were developed: 24 (55%) resources/equipment; 9 (21%) educational; 6 (14%) organizational changes; 2 (5%) staff communications; and 2 (5%) guidelines. Four (9%) service improvements were adopted trust wide. 32 (73%) LTs did not recur after service improvements. 24 (1%) of 1,946 PSIs were similar to LTs: 7 resource incidents, 7 catastrophic blood loss, 4 hyperkalaemia arrests, 3 emergency buzzer failures, and 3 difficulties contacting staff. 34 LTs (77%) were never recorded as PSIs. Conclusion: An in situ simulation program can identify important LTs which traditional reporting systems miss. Subsequent improvements in workplace systems and resources can improve efficiency and remove error traps. PMID- 29473024 TI - Plasmodium vivax Biology: Insights Provided by Genomics, Transcriptomics and Proteomics. AB - During the last decade, the vast omics field has revolutionized biological research, especially the genomics, transcriptomics and proteomics branches, as technological tools become available to the field researcher and allow difficult question-driven studies to be addressed. Parasitology has greatly benefited from next generation sequencing (NGS) projects, which have resulted in a broadened comprehension of basic parasite molecular biology, ecology and epidemiology. Malariology is one example where application of this technology has greatly contributed to a better understanding of Plasmodium spp. biology and host parasite interactions. Among the several parasite species that cause human malaria, the neglected Plasmodium vivax presents great research challenges, as in vitro culturing is not yet feasible and functional assays are heavily limited. Therefore, there are gaps in our P. vivax biology knowledge that affect decisions for control policies aiming to eradicate vivax malaria in the near future. In this review, we provide a snapshot of key discoveries already achieved in P. vivax sequencing projects, focusing on developments, hurdles, and limitations currently faced by the research community, as well as perspectives on future vivax malaria research. PMID- 29473027 TI - Morphology and Function of the Lamb Ileum following Preterm Birth. AB - Background: For infants born moderately/late preterm (32-37 weeks of gestation), immaturity of the intestine has the potential to impact both short- and long-term gastrointestinal function. The aim of this study conducted in sheep was to compare the morphology and smooth muscle contractility of the ileum in term and late preterm lambs. Materials and methods: Lambs delivered preterm (132 days gestation; n = 7) or term (147 days gestation; n = 9) were milk-fed after birth and euthanased at 2 days of age. A segment of distal ileum was collected for analysis of the length and cellular composition of the villi and crypts, smooth muscle width and contractility, and mRNA expression of the cell markers Ki67, lysozyme, mucin 2, synaptophysin, chromogranin A, olfactomedin 4, axis inhibition protein 2, and leucine-rich repeat-containing G-protein coupled receptor 5 (LGR5). Results: There was no difference in the proportion of inflammatory, proliferating, apoptotic, enterocyte, or goblet cells between groups, but preterm lambs exhibited a significant upregulation of the stem cell marker LGR5 (p = 0.01). Absolute villus height (term: 1,032 +/- 147 um, preterm: 651 +/- 52 um; p < 0.0001) and crypt depth (term: 153 +/- 11 um, preterm: 133 +/- 17 um; p = 0.01) were significantly shorter in the preterm ileums, with a trend (p = 0.06) for a reduction in muscularis externa width. There was no difference between groups in the contractile response to acetylcholine, but peak contractility in response to bradykinin (p = 0.02) and angiotensin II (p = 0.03) was significantly greater in the preterm lambs. Conclusion: Findings demonstrate that the crypt-villus units are shorter in the ileum of late preterm offspring, but functionally mature with an equivalent cellular composition and normal contractile response to acetylcholine compared with term offspring. The exaggerated contractility to inflammatory mediators evident in the preterm ileum, however, may be of concern. PMID- 29473028 TI - Results of Onlay Preputial Flap Urethroplasty for the Single-Stage Repair of Mid- and Proximal Hypospadias. AB - Aims: To report current results of preputial flap onlay urethroplasty using the principle of the total preputial flap (TPF) for the one-stage repair of mid- and proximal hypospadias. Methods: This study was a retrospective chart review of patients in a prospectively kept database of all hypospadias operations performed at two institutions from January 1 2011 to August 2017. Inclusion criteria: all patients who underwent hypospadias repair using a preputial only flap urethroplasty based on the principle of the TPF. Demographic data, duration of follow-up, complications, and reoperations were recorded. A successful result was considered to be a straight penis, a glanular meatus, and absence of voiding symptoms. Whenever possible an uroflow was obtained during the follow-up visits. Results: Forty-nine children met the inclusion criteria. All patients had marked penile curvature. Three patients had chromosomal abnormalities. The mean age at the time of surgery was 22 months (11-110) and the mean duration of follow-up 23.4 months (1-79). In 48 cases, the urethral plate could be preserved without dividing it. The penile curvature was corrected with chordectomy alone in 10 patients, 38 required a dorsal plication of the tunica albuginea, and 1 required an additional ventral dermal graft. In 38 patients (77.5%), the initial operation was successful, and no further operations were needed. There were eight urethrocutaneous fistulas, three dehiscences of the glans approximation. One patient suffered a wound infection and partial loss of the flap. Conclusion: One stage repair of mid- and proximal hypospadias preserving the urethral plate and using a TPF for the urethroplasty and coverage of the ventral penis is successful in 77.5% of cases. Complications in the remaining patients were easily managed or did not require treatment. Compared to a planned two-stage approach, the technique described in this report resulted in significantly fewer procedures till complete resolution of the problem. PMID- 29473030 TI - Public Health Investment in Team Care: Increasing Access to Clinical Preventive Services in Los Angeles County. AB - As part of federal and local efforts to increase access to high quality, clinical preventive services (CPS) in underserved populations, the Los Angeles County Department of Public Health (DPH) partnered with six local health system and community organization partners to promote the use of team care for CPS delivery. Although these partners were at different stages of organizational capacity, post program review suggests that each organization advanced team care in their clinical or community environments, potentially affecting >250,000 client visits per year. Despite existing infrastructure and DPH's funding support of CPS integration, partner efforts faced several challenges. They included lack of sustainable funding for prevention services; limited access to community resources that support disease prevention; and difficulties in changing health care provider behavior. Although team care can serve as a catalyst or vehicle for delivering CPS, downstream sustainability of this model of practice requires further state and national policy changes that prioritize prevention. Public health is well positioned to facilitate these policy discussions and to assist health system and community organizations in strengthening CPS integration. PMID- 29473029 TI - Fluoxetine Administration in Juvenile Monkeys: Implications for Pharmacotherapy in Children. AB - Fluoxetine therapy has been approved for children with major depressive disorder and obsessive compulsive disorder for over 14 years and has expanded to other childhood behavior disorders. As use increases, more detail on fluoxetine effects during juvenile brain development can help maintain safe and effective use of this therapy. Here, a narrative review is provided of previously published findings from a large nonhuman primate project. Fluoxetine was administered to juvenile male rhesus monkeys for an extended period (2 years) prior to puberty. Compared to controls, treated monkeys showed sleep disruption, facilitated social interaction, greater impulsivity, and impaired sustained attention during treatment. No effects on growth were seen. Metabolomics assays characterized a distinctive response to fluoxetine and demonstrated individual differences that were related to the impulsivity measure. Fluoxetine interactions with monoamine oxidase A polymorphisms that influenced behavior and metabolomics markers were an important, previously unrecognized finding of our studies. After treatment was discontinued, some behavioral effects persisted, but short-term memory and cognitive flexibility testing did not show drug effects. This detailed experimental work can contribute to clinical research and continued safe and effective fluoxetine pharmacotherapy in children. PMID- 29473032 TI - Zein Nanoparticles and Strategies to Improve Colloidal Stability: A Mini-Review. AB - Zein, a protein extracted from maize, can be employed to easily produce nanoscale particles suitable for use as carrier systems. This review investigates the main methods for obtaining zein nanoparticles, as well as the problems and options available in the development of stable colloidal suspensions. Considerable gaps were identified in the literature concerning this topic, with studies being unclear about the factors that affect the stability of zein particles. In the vast majority of cases, no data are presented in relation to the stability of the formulations over time. It could be concluded that in order to produce a high quality system, detailed evaluation is required, considering factors including the zein concentration, pH, ionic strength, thermal treatment of the protein prior to preparation of the nanoparticles, strategies employing other materials as coatings, and the storage conditions. It is extremely important that these aspects should be considered during product development, prior to commercial scale manufacture.

AB - Introduction: Cancer outcomes for people living in rural and remote areas are worse than for those living in urban areas. Although access to and quality of cancer treatment are important determinants of outcomes, delayed presentation has been observed in rural patients. Methods: Formative research with people from rural Western Australia (WA) led to the Find Cancer Early campaign. Find Cancer Early was delivered in three regions of WA, with two other regions acting as controls. Staff delivered the campaign using a community engagement approach, including promotion in local media. Television communications were not used to minimize contamination in the control regions. The campaign evaluation was undertaken at 20 months via a computer-assisted telephone interview (CATI) survey comparing campaign and control regions. The primary outcome variable was knowledge of cancer signs and symptoms. Results: Recognition and recall of Find Cancer Early and symptom knowledge were higher in the campaign regions. More than a quarter of those who were aware of the campaign reported seeing the GP as a result of their exposure. Conclusion: Despite limited use of mass media, Find Cancer Early successfully improved knowledge of cancer symptoms and possibly led to changes in behavior. Social marketing campaigns using community development can raise awareness and knowledge of a health issue in the absence of television advertising. PMID- 29473033 TI - Iron Based Catalysts Used in Water Treatment Assisted by Ultrasound: A Mini Review. AB - The characteristics and performances of catalyst are the key in catalytic ultrasonic treatment of wastewater, and iron based catalysts are known for low cost, high accessibility and safety. This paper reviewed the current research status of iron-based catalysts in water treatment assisted by ultrasound. Zero valent iron, Fe3O4 and iron composited with other metals were analyzed, their behaviors in catalytic sonochemistry were summarized, and the potential catalytic mechanisms were discussed in details. Finally, the future development in this field was proposed. PMID- 29473034 TI - Total Chemical Synthesis of Modified Histones. AB - In the post-genome era, epigenetics has received increasing attentions in recent years. The post-translational modifications (PTMs) of four core histones play central roles in epigenetic regulation of eukaryotic genome by either directly altering the biophysical properties of nucleosomes or by recruiting other effector proteins. In order to study the biological functions and structural mechanisms of these histone PTMs, an obligatory step is to prepare a sufficient amount of homogeneously modified histones. This task cannot be fully accomplished either by recombinant technology or enzymatic modification. In this context, synthetic chemists have developed novel protein synthetic tools and state-of-the art chemical ligation strategies for the preparation of homologous modified histones. In this review, we summarize the recent advances in the preparation of modified histones, focusing on the total chemical synthesis strategies. The importance and potential of synthetic chemistry for the study of histone code will be also discussed. PMID- 29473036 TI - Ethical and Philosophical Considerations for Gain-of-Function Policy: The Importance of Alternate Experiments. AB - The Department of Health and Human Services Framework for Guiding Funding Decisions about Proposed Research Involving Enhanced Potential Pandemic Pathogens (PPPs) contains a series of principles for governing the funding and conduct of gain-of-function (GOF) research resulting in the creation of PPPs. In this article, I address one of these principles, governing the replacement of GOF research with alternate experiments. I argue that the principle fails to address the way that different experiments can promote the same values as those promoted by GOF research resulting in PPPs. I then address some objections to this claim, and provide policy recommendations moving forward. PMID- 29473035 TI - The Role of Noncoding RNA Pseudouridylation in Nuclear Gene Expression Events. AB - Pseudouridine is the most abundant internal RNA modification in stable noncoding RNAs (ncRNAs). It can be catalyzed by both RNA-dependent and RNA-independent mechanisms. Pseudouridylation impacts both the biochemical and biophysical properties of RNAs and thus influences RNA-mediated cellular processes. The investigation of nuclear-ncRNA pseudouridylation has demonstrated that it is critical for the proper control of multiple stages of gene expression regulation. Here, we review how nuclear-ncRNA pseudouridylation contributes to transcriptional regulation and pre-mRNA splicing. PMID- 29473037 TI - Regulation of ER-Golgi Transport Dynamics by GTPases in Budding Yeast. AB - A large number of proteins are synthesized de novo in the endoplasmic reticulum (ER). They are transported through the Golgi apparatus and then delivered to their proper destinations. The ER and the Golgi play a central role in protein processing and sorting and show dynamic features in their forms. Ras super family small GTPases mediate the protein transport through and between these organelles. The ER-localized GTPase, Sar1, facilitates the formation of COPII transport carriers at the ER exit sites (ERES) on the ER for the transport of cargo proteins from the ER to the Golgi. The Golgi-localized GTPase, Arf1, controls intra-Golgi, and Golgi-to-ER transport of cargo proteins by the formation of COPI carriers. Rab GTPases localized at the Golgi, which are responsible for fusion of membranes, are thought to establish the identities of compartments. Recent evidence suggests that these small GTPases regulate not only discrete sites for generation/fusion of transport carriers, but also membrane dynamics of the organelles where they locate to ensure the integrity of transport. Here we summarize the current understandings about the membrane traffic between these organelles and highlight the cutting-edge advances from super-resolution live imaging of budding yeast, Saccharomyces cerevisiae. PMID- 29473038 TI - Signaling through the Primary Cilium. AB - The presence of single, non-motile "primary" cilia on the surface of epithelial cells has been well described since the 1960s. However, for decades these organelles were believed to be vestigial, with no remaining function, having lost their motility. It wasn't until 2003, with the discovery that proteins responsible for transport along the primary cilium are essential for hedgehog signaling in mice, that the fundamental importance of primary cilia in signal transduction was realized. Little more than a decade later, it is now clear that the vast majority of signaling pathways in vertebrates function through the primary cilium. This has led to the adoption of the term "the cells's antenna" as a description for the primary cilium. Primary cilia are particularly important during development, playing fundamental roles in embryonic patterning and organogenesis, with a suite of inherited developmental disorders known as the "ciliopathies" resulting from mutations in genes encoding cilia proteins. This review summarizes our current understanding of the role of these fascinating organelles in a wide range of signaling pathways. PMID- 29473040 TI - Direct Immunofluorescence Using Non-Lesional Buccal Mucosa in Mucous Membrane Pemphigoid. AB - Mucous membrane pemphigoid (MMP) is a rare organ-specific autoimmune subepithelial blistering disease with predominantly mucosal erosions, most frequently affecting the gingiva. Erosions in the oral cavity usually result in markedly decreased quality of life. The major autoantigens are BP180 and laminin332, which are components of basement membrane proteins in the skin and mucosa. Diagnosis is usually difficult due to histological destruction of the tissue and low autoantibody titers. In this study, we evaluated the diagnostic value of direct immunofluorescence (DIF) using non-lesional buccal mucosa in seven cases of MMP. In all seven patients, gingival lesions were clinically observed, and in one of the seven patients, buccal lesions were also clinically observed. First, we performed DIF to detect tissue-bound autoantibodies and complement. DIF from non-lesional buccal mucosa revealed linear deposits of IgG and C3 at the basement membrane zone in all cases. To detect autoantibodies, indirect immunofluorescence (IIF), BP180-NC16A ELISA and immunoblotting were performed. Surprisingly, circulating autoantibodies were unable to be detected in any of the cases by ELISA, IIF, or immunoblotting. Furthermore, histological separation was observed in one patient. In conclusion, DIF using non-lesional buccal mucosa was found to be superior to histological and serological tests for diagnosing mucous membrane pemphigoid. The procedure is technically easy and has high diagnostic value. PMID- 29473041 TI - The Role of Statins in Disease Modification and Cardiovascular Risk in Rheumatoid Arthritis. AB - Rheumatoid arthritis (RA) is an autoimmune, inflammatory disorder associated with excess cardiovascular morbidity and mortality. A complex interplay between traditional risk factors (dyslipidemia, insulin resistance, arterial hypertension, obesity, smoking) and chronic inflammation is implicated in the development of premature atherosclerosis and consequently in the higher incidence of cardiovascular events observed in RA patients. Despite the acknowledgment of elevated cardiovascular risk among RA individuals, its management remains suboptimal. While statin administration has a crucial role in primary and secondary cardiovascular disease prevention strategies as lipid modulating factors, there are limited data concerning the precise benefit of such therapy in patients with RA. Systemic inflammation and anti-inflammatory treatments influence lipid metabolism, leading to variable states of dyslipidemia in RA. Hence, the indications for statin therapy for cardiovascular prevention may differ between RA patients and the general population and the precise role of lipid lowering treatment in RA is yet to be established. Furthermore, some evidence supports a potential beneficial impact of statins on RA disease activity, attributable to their anti-inflammatory and immunomodulatory properties. This review discusses existing data on the efficacy of statins in reducing RA-related cardiovascular risk as well as their potential beneficial effects on disease activity. PMID- 29473042 TI - Combined Dietary Anthocyanins, Flavonols, and Stilbenoids Alleviate Inflammatory Bowel Disease Symptoms in Mice. AB - Dietary polyphenols are associated with a wide range of health benefits, protecting against chronic diseases and promoting healthy aging. Dietary polyphenols offer a complementary approach to the treatment of inflammatory bowel diseases (IBDs), a group of common chronic intestinal inflammation syndromes for which there is no cure. Tomato is widely consumed but its content of polyphenols is low. We developed a tomato variety, Bronze, enriched in three distinct classes of polyphenols: flavonols, anthocyanins, and stilbenoids. Using Bronze tomatoes as a dietary supplement as well as Indigo (high anthocyanins and flavonols), ResTom (high stilbenoids) and wild-type tomatoes, we examined the effects of the different polyphenols on the host gut microbiota, inflammatory responses, and the symptoms of chronic IBD, in a mouse model. Bronze tomatoes significantly impacted the symptoms of IBD. A similar result was observed using diets supplemented with red grape skin containing flavonols, anthocyanins, and stilbenoids, suggesting that effective protection is provided by different classes of polyphenols acting synergistically. PMID- 29473043 TI - Free Energy, Enthalpy and Entropy from Implicit Solvent End-Point Simulations. AB - Free energy is the key quantity to describe the thermodynamics of biological systems. In this perspective we consider the calculation of free energy, enthalpy and entropy from end-point molecular dynamics simulations. Since the enthalpy may be calculated as the ensemble average over equilibrated simulation snapshots the difficulties related to free energy calculation are ultimately related to the calculation of the entropy of the system and in particular of the solvent entropy. In the last two decades implicit solvent models have been used to circumvent the problem and to take into account solvent entropy implicitly in the solvation terms. More recently outstanding advancement in both implicit solvent models and in entropy calculations are making the goal of free energy estimation from end-point simulations more feasible than ever before. We review briefly the basic theory and discuss the advancements in light of practical applications. PMID- 29473044 TI - Cardiotoxicity of Anticancer Therapeutics. AB - As cancer therapeutics continues to improve and progress, the adverse side effects associated with anticancer treatments have also attracted more attention and have become extensively explored. Consequently, the importance of posttreatment follow-ups is becoming increasingly relevant to the discussion. Contemporary treatment methods, such as tyrosine kinase inhibitors, anthracycline chemotherapy, and immunotherapy regimens are effective in treating different modalities of cancers; however, these reagents act through interference with DNA replication or prevent DNA repair, causing endothelial dysfunction, generating reactive oxygen species, or eliciting non-specific immune responses. Therefore, cardiotoxic effects, such as hypertension, heart failure, and left ventricular dysfunction, arise posttreatment. Rising awareness of cardiovascular complications has led to meticulous attention for the evolution of treatment strategies and carefully monitoring between enhanced treatment effectiveness and minimization of adverse toxicity to the cardiovasculature, in which psychological assessments, early detection methods such as biomarkers, magnetic resonance imaging, and various drugs to reverse the damage from cardiotoxic events are more prevalent and their emphasis has increased tremendously. Fully understanding the mechanisms by which the risk factors action for various patients undergoing cancer treatment is also becoming more prevalent in preventing cardiotoxicity down the line. PMID- 29473045 TI - A Metabolomic Overview of Follicular Fluid in Cows. AB - Follicular fluid (FF) protects the oocyte against proteolysis and extrusion during ovulation, providing an appropriate microenvironment that favors proper embryonic development; thereby, FF plays a key role in embryo quality. Being directly related to cattle breeding, studying FF is extremely important in livestock science to measure cattle fertility. This may eventually help to assess the quality of both meat and milk, products widely consumed worldwide. There is an important commercial interest in the evaluation and characterization of compounds present in the FF of livestock that present greater likelihood of pregnancy. Mass spectrometry is a great ally for this type of analysis and can provide quick and efficient screening for molecular markers in biological samples. The present study demonstrated the potential of high-resolution mass spectrometry in analyzing FF samples from two distinct groups of Nellore cows (Bos indicus): high and low fertility, as determined by the number of oocytes produced. We were able to delineate markers of interest for each group, which may ultimately be related to biochemical pathways that lead to higher or lower reproductive performance. PMID- 29473046 TI - Duplications at 19q13.33 in patients with neurodevelopmental disorders. AB - Objective: After the recent publication of the first patients with disease associated missense variants in the GRIN2D gene, we evaluate the effect of copy number variants (CNVs) overlapping this gene toward the presentation of neurodevelopmental disorders (NDDs). Methods: We explored ClinVar (number of CNVs = 50,794) and DECIPHER (number of CNVs = 28,085) clinical databases of genomic variations for patients with copy number changes overlapping the GRIN2D gene at the 19q13.33 locus and evaluated their respective phenotype alongside their frequency, gene content, and expression, with publicly available reference databases. Results: We identified 11 patients with microduplications at the 19q13.33 locus. The majority of CNVs arose de novo, and comparable CNVs are not present in control databases. All patients were reported to have NDDs and dysmorphic features as the most common clinical phenotype (N = 8/11), followed by seizures (N = 6/11) and intellectual disability (N = 5/11). All duplications shared a consensus region of 405 kb overlapping 13 genes. After screening for duplication tolerance in control populations, positive gene brain expression, and gene dosage sensitivity analysis, we highlight 4 genes for future evaluation: CARD8, C19orf68, KDELR1, and GRIN2D, which are promising candidates for disease causality. Furthermore, investigation of the literature especially supports GRIN2D as the best candidate gene. Conclusions: Our study presents dup19q13.33 as a novel duplication syndrome locus associated with NDDs. CARD8, C19orf68, KDELR1, and GRIN2D are promising candidates for functional follow-up. PMID- 29473047 TI - Familial monophasic acute transverse myelitis due to the pathogenic variant in VPS37A. AB - Objective: To identify genetic differences among siblings with a family history of idiopathic transverse myelitis (ITM). Methods: We compared whole-exome sequencing (WES) on germline samples from the 2 affected sisters with ITM with 3 of their healthy siblings. Results: The 2 sisters with ITM both had acute onset of sensory loss in the legs, weakness, and bowel/bladder dysfunction. The first developed ITM at age 15 years with a clinical nadir of complete paralysis, which slowly recovered over a few years. MRI demonstrated a persistent T2 lesion in the lower thoracic cord. The second developed ITM at age 50 years with a nadir of sensory loss from T6 down and paraparesis in the legs, associated with an MRI lesion at T6. She also made a partial recovery with treatment. Both sisters are homozygous for a missense variant in VPS37A (c.700C>A, p.Leu234Ile) identified by WES. We performed targeted sequencing of VPS37A in an additional 86 samples from patients with ITM and 175 with other diseases to investigate the p.Leu234Ile variant. We identified another patient with ITM homozygous for the same rare variant. No patients with multiple sclerosis, neuromyelitis optica, other neurologic conditions, or any healthy controls in public databases were homozygous for this variant. Conclusions: A rare missense variant in VPS37A may predispose to development of ITM. Further studies are necessary to determine the frequency of this variant in the patient population and the mechanism through which it contributes to the risk of disease.

PMID- 29473049 TI - Late-onset and acute presentation of Brown-Vialetto-Van Laere syndrome in a Brazilian family. PMID- 29473039 TI - Surfactant Protein D in Respiratory and Non-Respiratory Diseases. AB - Surfactant protein D (SP-D) is a multimeric collectin that is involved in innate immune defense and expressed in pulmonary, as well as non-pulmonary, epithelia. SP-D exerts antimicrobial effects and dampens inflammation through direct microbial interactions and modulation of host cell responses via a series of cellular receptors. However, low protein concentrations, genetic variation, biochemical modification, and proteolytic breakdown can induce decomposition of multimeric SP-D into low-molecular weight forms, which may induce pro inflammatory SP-D signaling. Multimeric SP-D can decompose into trimeric SP-D, and this process, and total SP-D levels, are partly determined by variation within the SP-D gene, SFTPD. SP-D has been implicated in the development of respiratory diseases including respiratory distress syndrome, bronchopulmonary dysplasia, allergic asthma, and chronic obstructive pulmonary disease. Disease induced breakdown or modifications of SP-D facilitate its systemic leakage from the lung, and circulatory SP-D is a promising biomarker for lung injury. Moreover, studies in preclinical animal models have demonstrated that local pulmonary treatment with recombinant SP-D is beneficial in these diseases. In recent years, SP-D has been shown to exert antimicrobial and anti-inflammatory effects in various non-pulmonary organs and to have effects on lipid metabolism and pro-inflammatory effects in vessel walls, which enhance the risk of atherosclerosis. A common SFTPD polymorphism is associated with atherosclerosis and diabetes, and SP-D has been associated with metabolic disorders because of its effects in the endothelium and adipocytes and its obesity-dampening properties. This review summarizes and discusses the reported genetic associations of SP-D with disease and the clinical utility of circulating SP-D for respiratory disease prognosis. Moreover, basic research on the mechanistic links between SP-D and respiratory, cardiovascular, and metabolic diseases is summarized. Perspectives on the development of SP-D therapy are addressed. PMID- 29473050 TI - CYP2C19 variant mitigates Alzheimer disease pathophysiology in vivo and postmortem. AB - Objective: To verify whether CYP polymorphisms are associated with amyloid-beta (Abeta) pathology across the spectrum of clinical Alzheimer disease using in vivo and postmortem data from 2 independent cohorts. Methods: A candidate-gene approach tested the association between 5 genes (28 single nucleotide polymorphisms) and Abeta load measured in vivo by the global [18F]florbetapir PET standardized uptake value ratio (SUVR) in 338 Alzheimer's Disease Neuroimaging Initiative participants. Significant results were then tested using plasma Abeta and CSF Abeta and Abeta/phosphorylated tau (Abeta/p-tau) ratio in the same cohort. The significant association was also generalized to postmortem Abeta load measurement in the Rush Religious Orders Study/Memory and Aging Project cohorts. In addition, global cognition was used as a phenotype in the analysis in both cohorts. Results: Analysis of Abeta PET identified a variant in the CYP2C19 gene (rs4388808; p = 0.0006), in which carriers of the minor allele (MA) had a lower global SUVR. A voxel-wise analysis revealed that the variant is associated with a lower Abeta load in the frontal, inferior temporal, and posterior cingulate cortices. MA carriers also had higher CSF Abeta (p = 0.003) and Abeta/p-tau ratio (p = 0.02) but had no association with Abeta plasma levels. In postmortem brains, MA carriers had a lower Abeta load (p = 0.03). Global cognition was higher in MA carriers, which was found to be mediated by Abeta. Conclusions: Together, these findings point to an association between CYP2C19 polymorphism and Abeta pathology, suggesting a protective effect of the MA of rs4388808. Despite the several possibilities in which CYP2C19 affects brain Abeta, the biological mechanism by which this genetic variation may act as a protective factor merits further investigation. PMID- 29473052 TI - Novel hemizygous nonsense mutation in DRP2 is associated with inherited neuropathy. PMID- 29473051 TI - AP4 deficiency: A novel form of neurodegeneration with brain iron accumulation? AB - Objective: To describe the clinico-radiological phenotype of 3 patients harboring a homozygous novel AP4M1 pathogenic mutation. Methods: The 3 patients from an inbred family who exhibited early-onset developmental delay, tetraparesis, juvenile motor function deterioration, and intellectual deficiency were investigated by magnetic brain imaging using T1-weighted, T2-weighted, T2* weighted, fluid-attenuated inversion recovery, susceptibility weighted imaging (SWI) sequences. Whole-exome sequencing was performed on the 3 patients. Results: In the 3 patients, brain imaging identified the same pattern of bilateral SWI hyposignal of the globus pallidus, concordant with iron accumulation. A novel homozygous nonsense mutation was identified in AP4M1, segregating with the disease and leading to truncation of half of the adap domain of the protein. Conclusions: Our results suggest that AP4M1 represents a new candidate gene that should be considered in the neurodegeneration with brain iron accumulation (NBIA) spectrum of disorders and highlight the intersections between hereditary spastic paraplegia and NBIA clinical presentations. PMID- 29473053 TI - Dalfampridine is associated with de novo occurrence or reoccurrence of positive sensory symptoms in MS. PMID- 29473054 TI - Computed tomography scanning and stroke mortality in an urban medical unit in Cameroon. AB - Background: Despite the increasing availability of head computerized tomography (CT) in resource-limited settings, it is unclear if brain-imaging-based diagnosis of stroke affects the outcomes in the absence of dedicated structures for acute stroke management. Objectives: In a major referral hospital in the capital city of Cameroon, we compared in-hospital mortality rates in patients with a WHO-based diagnosis of stroke between participants with and without brain imaging on admission. Methods: Stroke patients with and without admission brain imaging were compared for demographic characteristics, risk factors, clinical and laboratory characteristic, and in-hospital mortality. Heterogeneities in mortality rates (CT vs. No CT) across major subgroups were investigated via interaction tests, and logistic regressions used to adjust for extraneous factors such as age, sex, year of study, residency, history of diabetes and hypertension, history of stroke, Glasgow coma scale, and delay between stroke symptoms onset and hospital admission. Results: Of the 1688 participants included in the final analysis, 1048 (62.1%) had brain imaging. The median age of the non-CT vs. CT groups was 65 vs. 62 years (p-value < 0.0001%). The death rate of non-CT vs. CT groups was 27.5% vs. 16.4% (p < 0.0001). This difference was mostly similar across major subgroups, and robust to the adjustments for confounders (in spite of substantial attenuation), with excess deaths in those with CT ranging from 65% to 149%. Conclusion: In this resource-limited environment, the absence of brain imaging on admission was associated with high in-hospital death from stroke, which was only partially explained by delayed hospitalization with severe disease. These results stressed the importance of scaling up acute stroke management in low- and middle income countries. PMID- 29473055 TI - MPV17-related hepatocerebral mitochondrial DNA depletion syndrome (MPV17-NNH) revisited. AB - MPV17-related hepatocerebral mitochondrial DNA depletion syndrome (previously known as Navajo neurohepatopathy) was discovered in children in the Four Corner's region of New Mexico approximately 40 years ago. This disease is associated with a single missense mutation in exon 2 in the MPV17 gene. The syndrome has now been recognized world-wide. We find that huge quantities of neurotoxins were present in archived nervous tissues from such patients. Arsenic was increased 18 *, cadmium ~ 10 *, cobalt 2.5 * and manganese 2.3 *; the largest increase was in mercury content 16,000 * compared to contemporaneous fresh-frozen normal nervous tissues. In the Four Corner's region of NM the life span is reduced compared to other parts of the United States and in our patients with MPV17-NNH the average life span was 5.4 years +/- 2.7 (SE) years. We now live in the Anthropocene an epoch characterized by large additions to the biosphere of neurotoxins. The effects of such toxic loads on human health and disease remain to be assessed. We speculate how such high neurotoxin content in tissues, which is likely to increase during the Anthropocene, may have influenced MPV17-NNH and similar phenotypes in different parts of the world. Our results imply that selenium supplementation to the diet in the Four Corner's region of NM might be beneficial to normal people and in the management of patients with MPV17-NNH syndrome. PMID- 29473056 TI - Testing cranial nerve VII: It is all in the wording. AB - During our practice of clinical neurological examination we frequently observed that patients, upon testing of cranial nerve VII, when instructed to "wrinkle their forehead" (to evaluate the innervation of the M. frontalis), seem to falsely "frown" (i.e. innervate the corrugator supercilii). Here, we set out to prospectively evaluate prevalence and characteristics of this phenomenon. Using a semi-structured questionnaire, we show that the majority of colleagues at our center shared our observation. Further, we demonstrate that of 113 unselected prospectively examined patients in fact 54.9% showed false frowning. This effect was irrespective of gender and only marginally influenced by age, chief complaint and clinical setting. Of note, all patients with initial frowning (or other "incorrect" reaction), when instructed to "raise their eye-brows", showed correct wrinkling. In summary, we were able to prospectively assess a highly prevalent artifact of the clinical exam, highlighting the critical significance of the correct wording during the neurological exam. PMID- 29473057 TI - Late-onset myasthenia gravis is predisposed to become generalized in the elderly. AB - Objective: The continuous increase in the number of patients presenting with late onset myasthenia gravis (LOMG) underscores the need for a better understanding of the clinical course and the establishment of an optimal therapeutic strategy. We aimed to clarify factors associated with clinical outcomes in LOMG. Methods: We retrospectively reviewed the clinical profiles of 40 patients with early-onset MG (EOMG) (onset age: 49 years or younger), 30 patients with non-elderly LOMG (onset age: 50-64 years), and 28 patients with elderly LOMG (onset age: 65 years or older) and compared the subgroups according to onset age and thymus status. The evaluated parameters were MGFA classification before treatment, MG-ADL score, complicating diseases, antibody titer, treatment, and MGFA post-intervention status. Results: Elderly LOMG patients showed transition to generalized symptoms at a higher frequency and underwent thymectomy less frequently than EOMG and non elderly LOMG patients (p < 0.001). The frequencies of crisis and plasmapheresis were significantly lower in thymectomized LOMG patients without thymoma than in thymectomized LOMG patients with thymoma or non-thymectomized LOMG patients (p < 0.01, P < 0.05, respectively). However, the outcome was not significantly different. All of the thymectomized LOMG patients without thymoma presenting with hyperplasia or thymic cyst had a favorable clinical course. Conclusions: Our study showed that elderly LOMG patients are more prone to severity, suggesting that they require aggressive immunomodulatory therapy. PMID- 29473059 TI - Assessing Community Cancer care after insurance ExpanSionS (ACCESS) study protocol. AB - Background: Cancer is the second most common cause of mortality in the United States. Cancer screening and prevention services have contributed to improved overall cancer survival rates in the past 40 years. Vulnerable populations (i.e., uninsured, low-income, and racial/ethnic minorities) are disproportionately affected by cancer, receive significantly fewer cancer prevention services, poorer healthcare, and subsequently lower survival rates than insured, white, non Hispanic populations. The Affordable Care Act (ACA) aims to provide health insurance to all low-income citizens and legal residents, including an expansion of Medicaid eligibility for those earning <=138% of federal poverty level. As of 2012, Medicaid was expanded in 32 states and the District of Columbia, while 18 states did not expand, creating a 'natural experiment' to assess the impact of Medicaid expansion on cancer prevention and care. Methods: We will use electronic health record data from up to 990 community health centers available up to 24 months before and at least one year after Medicaid expansion. Primary outcomes include health insurance and coverage status, and type of insurance. Additional outcomes include healthcare delivery, number and types of encounters, and receipt of cancer prevention and screening for all patients and preventive care and screening services for cancer survivors. Discussion: Cancer morbidity and mortality is greatly reduced through screening and prevention, but uninsured patients are much less likely than insured patients to receive these services as recommended. This natural policy experiment will provide valuable information about cancer-related healthcare services as the US tackles the distribution of healthcare resources and future health reform. Trial Registration: Clinicaltrails.gov identifier NCT02936609. PMID- 29473060 TI - The life of proteins under mechanical force. AB - Although much of our understanding of protein folding comes from studies of isolated protein domains in bulk, in the cellular environment the intervention of external molecular machines is essential during the protein life cycle. During the past decade single molecule force spectroscopy techniques have been extremely useful to deepen our understanding of these interventional molecular processes, as they allow for monitoring and manipulating mechanochemical events in individual protein molecules. Here, we review some of the critical steps in the protein life cycle, starting with the biosynthesis of the nascent polypeptide chain in the ribosome, continuing with the folding supported by chaperones and the translocation into different cell compartments, and ending with proteolysis in the proteasome. Along these steps, proteins experience molecular forces often combined with chemical transformations, affecting their folding and structure, which are measured or mimicked in the laboratory by the application of force with a single molecule apparatus. These mechanochemical reactions can potentially be used as targets for fighting against diseases. Inspired by these insightful experiments, we devise an outlook on the emerging field of mechanopharmacology, which reflects an alternative paradigm for drug design. PMID- 29473058 TI - Prevention, management, and rehabilitation of stroke in low- and middle-income countries. AB - Although stroke incidence in high-income countries (HICs) decreased over the past four decades, it increased dramatically in low- and middle-income countries (LMICs). In this review, we describe the current status of primary prevention, treatment, and management of acute stroke and secondary prevention of and rehabilitation after stroke in LMICs. Although surveillance, screening, and accurate diagnosis are important for stroke prevention, LMICs face challenges in these areas due to lack of resources, awareness, and technical capacity. Maintaining a healthy lifestyle, such as no tobacco use, healthful diet, and physical activity are important strategies for both primary and secondary prevention of stroke. Controlling high blood pressure is also critically important in the general population and in the acute stage of hemorrhagic stroke. Additional primary prevention strategies include community-based education programs, polypill, prevention and management of atrial fibrillation, and digital health technology. For treatment of stroke during the acute stage, specific surgical procedures and medications are recommended, and inpatient stroke care units have been proven to provide high quality care. Patients with a chronic condition like stroke may require lifelong pharmaceutical treatment, lifestyle maintenance and self-management skills, and caregiver and family support, in order to achieve optimal health outcomes. Rehabilitation improves physical, speech, and cognitive functioning of disabled stroke patients. It is expected that home- or community-based services and tele-rehabilitation may hold special promise for stroke patients in LMICs. PMID- 29473061 TI - First-principles study of intrinsic defects in formamidinium lead triiodide perovskite solar cell absorbers. AB - As an alternative to methylammonium lead triiodide (MAPbI3), formamidinium lead triiodide (FAPbI3) perovskites have recently attracted significant attention because of their higher stability and smaller band gaps. Here, based on first principles calculations, we investigate systematically the intrinsic defects in FAPbI3. While methylammonium (MA)-related defects MAI and IMA in MAPbI3 have high formation energies, we found that formamidinium (FA)-related defects VFA, FAI and IFA in FAPbI3 have much lower formation energies. Antisites FAI and IFA create deep levels in the band gap, and they can act as recombination centers and result in reduced carrier lifetimes and low open circuit voltages in FAPbI3-based photovoltaic devices. We further demonstrate that through cation mixing of MA and FA in perovskites the formation of these defects can be substantially suppressed.

However, the low detection sensitivity limits its application in trace biomarker analysis because of its extremely small sample size. To address the need for high sensitivity in MCE, we have developed an ultrasensitive MCE method based on a separation-assisted double cycling signal amplification strategy for the detection of microRNA (miRNA) in cell lysate. In this method, two short single-stranded DNAs P1 and P2 complement each other to form a duplex DNA probe (P1/P2). In the presence of target miRNA, P2 in the P1/P2 probe can be displaced to form double-stranded miRNA/P1. Then, the degradation of P1 in miRNA/P1 by T7 Exo releases the miRNA, and the released miRNA participates in a displacement reaction with another P1/P2 probe to complete the first cycle. The displaced free P2 hybridizes with the hairpin fluorescence probe (MB) to form the P2/MB duplex, which can also be degraded by T7 Exo to release P2. The released P2 can bind with another MB probe to complete the second cycle. By using MCE-laser induced fluorescence (LIF) as separation and detection platform and miRNA-141 as model analyte, the proposed MCE assay can detect miRNA-141 at concentrations as low as 8.0 fM, which is the highest sensitivity achieved to date for an MCE assay. This method for detecting trace miRNA holds great potential in biomedical research and clinical diagnosis.

AB - A pair of thallium salen derivatives was synthesized and characterized for potential use as monitors (or taggants) or as models for Group 13 complexes for subterranean fluid flows. These precursors were isolated from the reaction of thallium ethoxide with N,N'-bis(3,5-di-tert-butylsalicylidene)-ethylenediamine (H2-salo-But), or N,N'-bis(3,5-di-tert-butylsalicylidene)-1,2-phenylenediamine (H2-saloPh-But). The products were identified by single crystal X-ray diffraction as: [((MU-O)2,kappa1-(N)(N')salo-But)Tl2] (1) and {[((MU-O)2saloPh-But)Tl2][((MU O)2,kappa1-(N)(N')saloPh-But)Tl2]} (2). Both structures are similar, wherein each O atom of the salo moiety bridges the two Tl atoms, leading to a TlTl interaction, which is further stabilized by an intramolecular pi-bond with neighboring phenyl rings. For 1, an additional TlN interaction was solved for each metal center; whereas, for 2, one of the two molecules in the matrix has a weak TlN interaction but no bonding noted in the other molecule. Both Density Functional Theory (DFT) calculations and variable temperature solution 205Tl NMR studies of 1 and 2 further confirmed the TlTl interaction. The UV-vis absorbance spectra of these compounds had an absorbance peak at 392 nm for 1 and a broad absorbance peak centered at 469 nm for 2, which were found to be in good agreement with the DFT calculated spectra that were dominated by the singlet state. Fluorescence emission and excitation studies reveal absorptions at 360 and 380 nm for 1 and 2, respectively, which are attributed to the TlTl metal centers. To demonstrate practicality, fluorescence spectra of 1 and 2 were obtained using a handheld 405 nm cw laser pointer and portable spectrometer where compound 1 was found to glow 15 times brighter than compound 2. Only compound 1 was found to survive the simulated deep-well conditions explored, which was attributed to the TlN interaction noted for 1 but not for 2. PMID- 29473064 TI - Promiscuous hydrogen in polymerising plasmas. AB - Historically, there have been two opposing views regarding deposition mechanisms in plasma polymerisation, radical growth and direct ion deposition, with neither being able to fully explain the chemistry of the resultant coating. Deposition rate and film chemistry are dependent on the chemistry of the plasma phase and thus the activation mechanisms of species in the plasma are critical to understanding the relative contributions of various chemical and physical routes to plasma polymer formation. In this study, we investigate the roles that hydrogen plays in activating and deactivating reactive plasma species. Ethyl trimethylacetate (ETMA) is used as a representative organic precursor, and additional hydrogen is added to the plasma in the form of water and deuterium oxide. Optical emission spectroscopy confirms that atomic hydrogen is abundant in the plasma. Comparison of the plasma phase mass spectra of ETMA/H2O and ETMA/D2O reveals that (1) proton transfer from hydronium is a common route to charging precursors in plasma, and (2) hydrogen abstraction (activation) and recombination (deactivation) processes are much more dynamic in the plasma than previously thought. Consideration of the roles of hydrogen in plasma chemistry may then provide a more comprehensive view of deposition processes and bridge the divide between the two disparate schools of thought.

AB - An unprecedented Fe2Pc3 metallo-organic helicate has been assembled using a bidentate phthalocyanine (Pc) ligand, 2-formylpyridine and Fe(OTf)2.

Photoactivated electronic interactions between components occur in the host-guest complex. PMID- 29473066 TI - Mono- and dinuclear tetraphosphabutadiene ferrate anions. AB - Reduction of [CpArFe(MU-Br)]2 (1, CpAr = C5(C6H4-4-Et)5) by potassium napthalenide, followed by the addition of white phosphorus, affords [K(18-c 6){CpArFe(eta4-P4)}] (2, 18-c-6 = [18]crown-6), which features a planar cyclo-P42 ligand. The related diiron complex [Na2(THF)5(CpArFe)2(MU,eta4:4-P4)] (3) was obtained by reducing 1 with sodium amalgam in the presence of P4. Protonation of 3 affords [Na(THF)3][(CpArFe)2(MU,eta4:4-P4)(H)] (4), while the reaction of 3 with trimethylchlorosilane gives the nortricyclane compound P7(SiMe3)3 as the main product.

AB - A new signal amplification system with an auto-inductive mode of action and distinct chemiluminescence output was developed. The system is composed of a unique structural motif that combines a chemiexcitation mechanism with a quinone methide elimination into a signal building block. As demonstrated with a probe designed to detect fluoride, an auto-inductive chemiluminescence signal amplification was obtained through self-immolative disassembly and light emission mechanisms.

AB - Preparation of substituent-diverse, triazole-iduronic acid hybrid molecules by click reaction of an azido iduronic acid derivative with randomly chosen alkynes is described. Library members were screened for their ability to inhibit alpha-l iduronidase, and hit molecules and analogues were then investigated for their ability to stabilize rh-alpha-IDUA in a thermal denaturation study. This work resulted in the discovery of the first small molecules that can be used to stabilize exogenous rh-alpha-IDUA protein in vitro. PMID- 29473069 TI - pH and generation dependent morphologies of PAMAM dendrimers on a graphene substrate. AB - The adsorption of PAMAM dendrimers at solid/water interfaces has been extensively studied, and is mainly driven by electrostatic and van der Waals interactions between the substrate and the dendrimers. However, the pH dependence of the adsorption driven predominantly by the van der Waals interactions is poorly explored, although it is crucial for investigating the potentiality of these dendrimers in supercapacitors and surface patterning. Motivated by this aspect, we have studied the adsorption behavior of PAMAM dendrimers of generations 2 (G2) to 5 (G5) with pH and salt concentration variation, on a charge neutral graphene substrate, using fully atomistic molecular dynamics simulations. The instantaneous snapshots from our simulations illustrate that the dendrimers deform significantly from their bulk structures. Based on various structural property calculations, we classify the adsorbed dendrimer morphologies into five categories and map them to a phase diagram. Interestingly, the morphologies we report here have striking analogies with those reported in star-polymer adsorption studies. From the fractional contacts and other structural property analyses we find that the deformations are more pronounced at neutral pH as compared to high and low pH. Higher generation dendrimers resist deformation following the deformation trend, G2 > G3 > G4 > G5 at any given pH level. As the adsorption here is mainly driven by van der Waals interactions, we observe no desorption of the dendrimers as the salt molarity is increased, unlike that reported in the electrostatically driven adsorption studies. PMID- 29473070 TI - Grape seed proanthocyanidins influence gut microbiota and enteroendocrine secretions in female rats. AB - Grape seed proanthocyanidin extract (GSPE) modulates several parameters involved in metabolic syndrome. GSPE is a mixture of compounds, some which are rapidly absorbed, while others remain in the lumen where they might have effects that are translated to the whole organism. Our aim was to decipher if the 8-day treatment of GSPE, previously shown to reduce food intake, induces changes in the microbiota and enterohormone secretion. The ratio of Firmicutes : Bacteroidetes was lower in the microbiota of GSPE-treated rats compared to controls, and differences in several taxonomic families and genera were observed. Such modulation led to a reduction in cecal butyrate content. GSPE also increased plasma glucagon-like-peptide-1 (GLP-1). Gallic acid did not induce major changes in the microbiota profile nor in GLP-1 secretion. Correlations between several microbiota taxa and plasma triacylglycerol, adiposity, and enterohormones were observed. Modulation of microbiota may be one of the mechanism by which GSPE impacts metabolic health. PMID- 29473071 TI - Spectroelectrochemical studies of a ruthenium complex containing the pH sensitive 4,4'-dihydroxy-2,2'-bipyridine ligand. AB - Attaining high oxidation states at the metal center of transition metal complexes is a key design principle for many catalytic processes. One way to support high oxidation state chemistry is to utilize ligands that are electron-donating in nature. Understanding the structural and electronic changes of metal complexes as higher oxidation states are reached is critical towards designing more robust catalysts that are able to turn over at high rates without decomposing. To this end, we report herein the changes in structural and electronic properties as [Ru(bpy)2(44'bpy(OH)2)]2+ is oxidized to [Ru(bpy)2(44'bpy(OH)2)]3+ (bpy = 2,2' bipyridine; 44'bpy(OH)2 = 4,4'-dihydroxy-2,2'-bipyridine). The 44'bpy(OH)2 ligand is a pH-dependent ligand where deprotonation of the hydroxyl groups leads to significant electronic donation to the metal center. A Pourbaix Diagram of the complex reveals a pH independent reduction potential below pH = 2.0 for the Ru3+/2+ process at 0.91 V vs. Ag/AgCl. Above pH = 2.0, pH dependence is observed with a decrease in reduction potential until pH = 6.8 where the complex is completely deprotonated, resulting in a reduction potential of 0.62 V vs. Ag/AgCl. Spectroelectrochemical studies as a function of pH reveal the disappearance of the Metal to Ligand Charge Transfer (MLCT) or Mixed Metal-Ligand to Charge Transfer bands upon oxidation and the appearance of a new low energy band. DFT calculations for this low energy band were carried out using both B3LYP and M06-L functionals for all protonation states and suggest that numerous new transition types occur upon oxidation to Ru3+. PMID- 29473072 TI - Numerical-experimental observation of shape bistability of red blood cells flowing in a microchannel. AB - Red blood cells flowing through capillaries assume a wide variety of different shapes owing to their high deformability. Predicting the realized shapes is a complex field as they are determined by the intricate interplay between the flow conditions and the membrane mechanics. In this work we construct the shape phase diagram of a single red blood cell with a physiological viscosity ratio flowing in a microchannel. We use both experimental in vitro measurements as well as 3D numerical simulations to complement the respective other one. Numerically, we have easy control over the initial starting configuration and natural access to the full 3D shape. With this information we obtain the phase diagram as a function of initial position, starting shape and cell velocity. Experimentally, we measure the occurrence frequency of the different shapes as a function of the cell velocity to construct the experimental diagram which is in good agreement with the numerical observations. Two different major shapes are found, namely croissants and slippers. Notably, both shapes show coexistence at low (<1 mm s-1) and high velocities (>3 mm s-1) while in-between only croissants are stable. This pronounced bistability indicates that RBC shapes are not only determined by system parameters such as flow velocity or channel size, but also strongly depend on the initial conditions. PMID- 29473073 TI - Insights from ion mobility-mass spectrometry, infrared spectroscopy, and molecular dynamics simulations on nicotinamide adenine dinucleotide structural dynamics: NAD+vs. NADH. AB - Nicotinamide adenine dinucleotide (NAD) is found in all living cells where the oxidized (NAD+) and reduced (NADH) forms play important roles in many enzymatic reactions. However, little is known about NAD+ and NADH conformational changes and kinetics as a function of the cell environment. In the present work, an analytical workflow is utilized to study NAD+ and NADH dynamics as a function of the organic content in solution using fluorescence lifetime spectroscopy and in the gas-phase using trapped ion mobility spectrometry coupled to mass spectrometry (TIMS-MS) and infrared multiple photon dissociation (IRMPD) spectroscopy. NAD solution time decay studies showed a two-component distribution, assigned to changes from a "close" to "open" conformation with the increase of the organic content. NAD gas-phase studies using nESI-TIMS-MS displayed two ion mobility bands for NAD+ protonated and sodiated species, while four and two ion mobility bands were observed for NADH protonated and sodiated species, respectively. Changes in the mobility profiles were observed for NADH as a function of the starting solution conditions and the time after desolvation, while NAD+ profiles showed no dependence. IRMPD spectroscopy of NAD+ and NADH protonated species in the 800-1800 and 3200-3700 cm-1 spectral regions showed common and signature bands between the NAD forms. Candidate structures were proposed for NAD+ and NADH kinetically trapped intermediates of the protonated and sodiated species, based on their collision cross sections and IR profiles. Results showed that NAD+ and NADH species exist in open, stack, and closed conformations and that the driving force for conformational dynamics is hydrogen bonding of the N-H-O and O-H-O forms with ribose rings. PMID- 29473074 TI - Balancing silicon/aluminum oxide junctions for super-plasmonic emission enhancement of quantum dots via plasmonic metafilms. AB - We study the impact of structural features of Si/Al oxide junctions on metal oxide plasmonic metafilms formed via placing such junctions in close vicinity of an Au/Si Schottky barrier. The emission intensity and dynamics of colloidal semiconductor quantum dots deposited on such metafilms are investigated, while the surface morphology and structural compositions of the Si/Al oxide junction are controlled. The results show the conditions wherein the Si/Al oxide junction can reshape the impact of plasmonic effects, allowing it to increase the lifetimes of excitons. Under these conditions, the plasmonic metafilms can quarantine excitons against the fluctuating trap environments of the quantum dots, offering super-plasmonic emission enhancement that includes enhancement of the spontaneous emission decay rate combined with the suppression of Auger decay. PMID- 29473076 TI - Impact of cathepsin B-sensitive triggers and hydrophilic linkers on in vitro efficacy of novel site-specific antibody-drug conjugates. AB - Herein we describe the synthesis and evaluation of four novel HER2-targeting, cathepsin B-sensitive antibody-drug conjugates bearing a monomethylauristatin E (MMAE) cytotoxic payload, constructed via the conjugation of cleavable linkers to trastuzumab using a site-specific bioconjugation methodology. These linkers vary by both cleavable trigger motif and hydrophilicity, containing one of two cathepsin B sensitive dipeptides (Val-Cit and Val-Ala), and engendered with either hydrophilic or hydrophobic character via application of a PEG12 spacer. Through evaluation of physical properties, in vitro cytotoxicity, and receptor affinity of the resulting antibody-drug conjugates (ADCs), we have demonstrated that while both dipeptide triggers are effective, the increased hydrophobicity of the Val-Ala pair limits its utility within this type of linker. In addition, while PEGylation augments linker hydrophilicity, this change does not translate to more favourable ADC hydrophilicity or potency. While all described structures demonstrated excellent and similar in vitro cytotoxicity, the ADC with the ValCitPABMMAE linker shows the most promising combination of in vitro potency, structural homogeneity, and hydrophilicity, warranting further evaluation into its therapeutic potential.

AB - Osteoarthritis (OA) is an age-related degenerative disease and is the fourth major cause of disability, but there are no effective therapies because of its complex pathology and the side effects of the drugs. Previous research demonstrated that inflammation and ECM degradation play major roles in OA development. Monascin is an azaphilonoid pigment extracted from Monascus fermented rice with a potential anti-inflammatory effect reported in various preclinical studies. In the present study, we investigated the protectiveness of monascin on interleukin (IL)-1beta-induced mouse chondrocytes and surgical destabilization of the medial meniscus mouse (DMM) OA models. In vitro, monascin treatment inhibited the IL-1beta-induced expression of cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), nitric oxide (NO), prostaglandin E2 (PGE2), tumor necrosis factor alpha (TNF-alpha), and interleukin-6 (IL-6). In addition, the IL-1beta-stimulated matrix metalloproteinase-13 (MMP-13) and thrombospondin motifs 5 (ADAMTS-5) upregulation and type two collagen and aggrecan degradation were reversed by monascin. Mechanistically, we revealed that monascin suppressed nuclear factor kappa B (NF-kappaB) signalling by activating the nuclear factor (erythroid-derived 2)-like 2 (Nrf2) in IL-1beta-induced chondrocytes. And monascin-induced protectiveness in OA development was also shown by using a DMM model. Altogether, our results suggested that monascin could be a novel therapeutic approach for OA.

AB - In this paper, we report an efficient synthetic method for thioester formation from sodium thiosulfate pentahydrate, organic halides, and aryl anhydrides. In the one-pot two-step reactions developed in this study, sodium thiosulfate was used as the sulfur surrogate for acylation with anhydrides, followed by substitution with organic halides through the in situ generation of thioaroylate. Furthermore, two important organic compounds could be successfully synthesized using our developed method. The advantages of the one-pot two-step reactions are operational simplicity, structurally diverse products with 42%-90% yields, use of relatively low toxic and odourless reagents, and easy applicability to large scale operation. PMID- 29473085 TI - Crystallographic orientation of facets and planar defects in functional nanostructures elucidated by nano-focused coherent diffractive X-ray imaging. AB - The physical and chemical properties of nanostructures depend on their surface facets. Here, we exploit a pole figure approach to determine the three dimensional orientation matrix of a nanostructure from a single Bragg reflection measured with a coherent nano-focused X-ray beam. The signature of any truncated (faceted) crystal produces a crystal truncation rod, which corresponds to a streak of intensity in reciprocal space normal to the surface. When two or more non-parallel facets are present, both the crystal orientation and the crystal facets can be identified. This enables facets to be rapidly indexed and uncommon facets, and planar defects, that have been difficult to study before to be identified. We demonstrate the technique with (i) epitaxial core-shell InGaN/GaN multiple quantum-wells grown on GaN nanowires, where surface facets and planar defects are determined, and (ii) single randomly oriented highly faceted tetrahedrahexal Pt nanoparticles. The methodology is applicable to a broad range of nanocrystals and provides a unique insight into the connection between structure and properties of nanomaterials.

AB - Developing cheap, highly efficient and stable electrocatalysts for both oxygen and hydrogen evolution reactions (OER and HER) is extremely meaningful to realize large-scale implementation of water splitting technology. Herein, we report the phase and composition controlled synthesis of cobalt sulfide (CoSx) hollow nanospheres (HNSs) and their catalytic efficiencies for hydrogen and oxygen evolution reactions in alkaline media. Three CoSx compounds, i.e., Co9S8, Co3S4, and CoS2 HNSs, were precisely synthesized by simply adjusting the molar ratio of carbon disulfide to cobalt acetate using a facile solution-based strategy. Electrochemical results reveal that the as-prepared CoS2 HNSs exhibit superior OER and HER catalytic performance to Co9S8 and Co3S4 HNSs in 1.0 M KOH, with overpotentials of 290 mV for the OER and 193 mV for the HER at 10 mA cm-2, and the corresponding Tafel slopes of 57 and 100 mV dec-1, respectively. In addition, the CoS2 HNSs exhibit remarkable long-term catalytic durability, which is even superior to precious metal catalysts of RuO2 and Pt/C. Moreover, an alkaline electrolyzer assembled using CoS2 HNSs as both anode and cathode materials can achieve 10 mA cm-2 at a low cell voltage of 1.54 V at 60 degrees C with a faradaic efficiency of 100% for overall water splitting. Further analysis demonstrates that the surface morphology, crystallographic structure and coordination environment of Con+ active sites in combination determine the HER/OER activities in the synthesized binary CoSx series, which would provide insight into the rational design of transition metal chalcogenides for highly efficient hydrogen and oxygen-involved electrocatalysis.

AB - A series of carbazole based ligands with different lengths were assembled with nickel ions to construct metal-organic macrocycles.

Combining with the structural analysis of their solid confirmation, it was revealed that the diversity of the metal-organic macrocycles was increased with the flexibility of the ligands. PMID- 29473088 TI - A glimpse into the regulation of the Wilson disease protein, ATP7B, sheds light on the complexity of mammalian apical trafficking pathways. AB - Wilson disease (WD), a Mendelian disorder of copper metabolism caused by mutations in the ATP7B gene, manifests a large spectrum of phenotypic variability. This phenomenon of extensive symptom variation is not frequently associated with a monogenic disorder. We hypothesize that the phenotypic variability in WD is primarily driven by the variations in interacting proteins that regulate the ATP7B function and localization in the cell. Based on existing literature, we delineated a potential molecular mechanism for ATP7B mediated copper transport in the milieu of its interactome, its dysfunction in WD and the resulting variability in the phenotypic manifestation. Understanding the copper induced apical trafficking of ATP7B also significantly contributes to the appreciation of the complexities of the ligand-induced transport pathway. We believe that this holistic view of WD will pave the way for a better opportunity for rational drug design and therapeutics. PMID- 29473089 TI - The Effects of Cariprazine and Aripiprazole on PCP-Induced Deficits on Attention Assessed in the 5-Choice Serial Reaction Time Task. AB - RATIONALE: Attentional processing deficits are a core feature of schizophrenia, likely contributing to the persistent functional and occupational disability observed in patients with schizophrenia. The pathophysiology of schizophrenia is hypothesized to involve dysregulation of NMDA receptor-mediated glutamate transmission, contributing to disruptions in normal dopamine transmission. Preclinical investigations often use NMDA receptor antagonists, such as phencyclidine (PCP), to induce cognitive disruptions relevant to schizophrenia. We sought to test the ability of partial dopamine D2/D3 agonists, cariprazine and aripiprazole, to attenuate PCP-induced deficits in attentional performance. OBJECTIVES: The objective of this study is to determine whether systemic administration of cariprazine or aripiprazole attenuated 5-choice serial reaction time task (5-CSRTT) deficits induced by repeated exposure to PCP. METHODS: We utilized a repeated PCP-treatment regimen (2 mg/kg, subcutaneous [s.c.], once daily for 5 days) in rats to induce deficits in the 5-CSRTT. Rats were pre treated with cariprazine (0.03, 0.1, or 0.3 mg/kg, oral [p.o.]) or aripiprazole (1, 3, or 10 mg/kg, p.o.) to determine whether they prevented PCP-induced deficits in the 5-CSRTT performance. RESULTS: PCP treatment increased inappropriate responding in the 5-CSRTT, elevating incorrect, premature, and timeout responses. Cariprazine treatment reduced PCP-induced increases in inappropriate responding. However, at higher doses, cariprazine produced non specific response suppression, confounding interpretation of the attenuated PCP induced deficits. Aripiprazole treatment also attenuated PCP-induced deficits; however, unlike cariprazine treatment, aripiprazole reduced correct responding and increased omissions. CONCLUSIONS: Cariprazine and aripiprazole both demonstrated potential in attenuating PCP-induced deficits in the 5-CSRTT performance. While both compounds produced non-specific response suppression, these effects were absent when 0.03 mg/kg cariprazine was administered.

AB - Teleosts have many spawning strategies and the hormonal control of gametogenesis is not well defined among the species or even, between sexes. To increase the knowledge of gonadotropin hormones, we studied the trend by gene expression of gonadotropin receptors in the follicles and testis at different maturity stages in the European hake (Merluccius merluccius), a multiple-spawning species. With this aim, fshr and lhr were sequenced, characterized, and their gene expression was quantified in oocytes and in testes at different maturity stages. The deduced amino acid sequences were used to phylogenetic studies and evidenced that both receptors are phylogenetically closed to other gadoid species. The gene expression of both receptors was poorly expressed in primary follicles, increased in vitellogenic follicles and to later decrease in hydrated oocytes. In testis, highest levels of lhr were detected during spermiation, while levels of fshr were constant. For the first time, a histological analysis was performed in European hake testes showing an unrestricted lobular testis. To better elucidate the mechanisms involved in the oogenesis of the European hake, the expression of estrogen receptor and cyp19a was also investigated displaying high levels in all classes of follicles. All these data allow to increase the knowledge on reproductive physiology of an important socioeconomical species and it seeks to shed more light on the role of the receptors here studied during gametogenesis of multiple-spawning fish. PMID- 29473091 TI - Mechanisms Through Which Supportive Relationships with Parents and Peers Mitigate Victimization, Depression and Internalizing Problems in Children Bullied by Peers. AB - This study investigated how supportive relationships with peers and parents protect children against ongoing victimization, internalizing problems and depression. The longitudinal data set tracked progress of 111 children recruited for the trial of Resilience Triple P, and previously bullied by peers. Informants included children, parents and teachers. Higher levels of facilitative parenting (warm parenting that supports peer relationships) and peer acceptance predicted lower later levels of both depression and victimization over time. Higher levels of child friendedness predicted lower levels of child reports of internalizing problems. Children's friendships, acceptance by same sex peers and facilitative parenting all played moderating roles in protecting against ongoing victimization and internalizing problems. Peer acceptance mediated the relationships between facilitative parenting and victimization. Facilitative parenting mediated the relationship between peer acceptance and depression. It was concluded that supportive relationships with parents and peers play important and complementary roles in protecting children against ongoing victimization and depression.

AB - A four-pulse pattern of transcranial magnetic stimulation (TMS) was compared to traditional dual-pulse TMS for its ability to modulate motor cortical excitability. This novel pattern consisted of a three-pulse train of subthreshold conditioning pulses followed by a suprathreshold test pulse (i.e., SC-T). The intervals between these superconditioning (SC) pulses (1, 3, or 6 ms) and the follow-on test pulse (1, 3, 10, or 25 ms) were varied, and the resultant MEPs were compared to those elicited by: (1) single-pulse TMS; and (2) dual-pulse conditioning-test (C-T) TMS with either short (3 ms) or long (10 ms) intervals to elicit short-interval intracortical inhibition (SICI) or intracortical facilitation (ICF), respectively. Testing included abductor pollicis brevis (APB) and tibialis anterior (TA) in 15 neurologically normal adults. For superconditioning inputs, 10 ms test intervals caused especially strong facilitation of the test MEP, while 1 ms test intervals were particularly effective at causing inhibition of the test response. For both muscles and across all subjects, the most effective of the 12 SC-T inputs tested for causing either facilitation or inhibition was-with rare exception-superior to the dual-pulse TMS input for causing facilitation (i.e., ICF) or inhibition (i.e., SICI), while the overall magnitude of effect was more pronounced in APB compared to TA. Nevertheless, after normalization, the impact of a superconditioning input train on the test MEP was similar in APB and TA muscles, suggesting similar mechanisms of action. Limited findings from a single subject with amyotrophic lateral sclerosis (ALS) are included to further illustrate the potential advantages of using a train of conditioning pulses preceding a TMS test pulse to selectively investigate abnormal motor cortical excitatory and inhibitory circuitry. PMID- 29473093 TI - Assessment of iodine uptake by pancreatic cancer following chemotherapy using dual-energy CT. AB - Pancreatic cancer remains a major health problem, and only less than 20% of patients have resectable disease at the time of initial diagnosis. Systemic chemotherapy is often used in the patients with borderline resectable, locally advanced unresectable disease and metastatic disease. CT is often used to assess for therapeutic response; however, conventional imaging including CT may not correctly reflect treatment response after chemotherapy. Dual-energy (DE) CT can acquire datasets at two different photon spectra in a single CT acquisition, and permits separating materials and extract iodine by applying a material decomposition algorithm. Quantitative iodine mapping may have an added value over conventional CT imaging for monitoring the treatment effects in patients with pancreatic cancer and potentially serve as a unique biomarker for treatment response. In this pictorial essay, we will review the technique for iodine quantification of pancreatic cancer by DECT and discuss our observations of iodine quantification at baseline and after systemic chemotherapy with conventional cytotoxic agents, and illustrate example cases.

AB - Despite the fact that there are numerous reports on muscular variations in the sole of the foot, routine dissection in a formaldehyde-fixed cadaver revealed an accessory flexor digiti quinti muscle, which to the best of our knowledge is a very unusual variant. This was in the form of a slender, 38 mm long muscular slip, with a proximal and distal tendon extending from the common flexor digitorum longus tendinous plate out to the distal phalanx of the fifth toe. An associated finding was the absence of the musculotendinous portion of the flexor digitorum brevis to the same toe. A developmental explanation for this variation is presented. Clinical implications with regard to this anatomical condition may result in clawing of the fifth toe.

AB - BACKGROUND AND AIMS: Pancreatic ductal adenocarcinoma (PDAC) represents the fourth cause of cancer-related death. We aimed to evaluate whether gemcitabine treatment shapes the gut microbiota in a model of PDAC xenografted mice. MATERIALS AND METHODS: Pancreatic cancer xenograft mice were subjected to gemcitabine injection once per week for 3 weeks to assess the tumor volume as compared to control mice injected with normal saline solution. The composition of fecal microbiota, the activation of NF-kB pathway in cancer tissues and the serum metabolomics were further analyzed. RESULTS: Gemcitabine considerably decreases the proportion of Gram- positive Firmicutes (from about 39 to 17%) and the Gram- negative Bacteroidetes (from 38 to 17%) which are the two dominant phyla in the gut of tumor-bearing control mice. This downshift was replaced by an increase of Proteobacteria (Escherichia coli and Aeromonas hydrophila) from 15 up to 32% and Verrucomicrobia (Akkermansia muciniphila) from 5 to 33% in the gut of drug receiving mice. An overall increase in inflammation-associated bacteria was observed upon gemcitabine. Consistently, activation of the NF-kB canonical pathway was found in cancer tissues from gemcitabine-treated mice. Serum metabolomics revealed a significant decrease of the purine compounds inosine and xanthine, and a decreasing trend for their metabolically-related molecule hypoxanthine. DISCUSSION: Understanding chemotherapy side effects may explain the lack of activity or the chemoresistant processes and it may help to set up strategies to improve the effectiveness of therapy.

AB - To assess the association of ankylosing spondylitis (AS) and ischemic heart disease (IHD) compared to traditional cardiovascular (CV) risk factors. Primary care and hospital records of patients with AS were analyzed, using the largest health maintenance organization in Israel, the "Clalit" Health Services data. These patients were compared with age- and gender-matched controls regarding the proportion of IHD in a cross-sectional study. Parameters including socioeconomic status, body mass index (BMI), smoking habits, and coexistent medical conditions hypertension, hyperlipidemia, and diabetes mellitus (DM) - as well as the use of NSAIDs and anti-TNFs were also assessed. The study included 4076 AS patients compared to 20,290 age- and gender-matched controls without AS. The proportion of IHD was higher among AS patients as compared to controls (14.1 vs. 6.36%, respectively, p < 0.01) and patients treated with anti-TNFs had a lower risk for IHD compared to non-anti-TNF users. The proportion of hypertension, hyperlipidemia, DM, and smoking was also higher among AS patients. However, in multivariate analyses following adjustment to these risk factors, AS was not found to be associated with IHD nor anti-TNF therapy to be a protective factor. Patients with AS have more traditional CV risk factors, thus are in a higher risk for IHD. AS itself was not shown to be independently associated with IHD. These findings emphasize the multifactorial process leading to increased proportion of IHD among AS patients and the need for a stringent control of traditional risk factors in these patients. PMID- 29473099 TI - The filamentous fungal pellet-relationship between morphology and productivity. AB - Filamentous fungi are used for the production of a multitude of highly relevant biotechnological products like citric acid and penicillin. In submerged culture, fungi can either grow in dispersed form or as spherical pellets consisting of aggregated hyphal structures. Pellet morphology, process control and productivity are highly interlinked. On the one hand, process control in a bioreactor usually demands for compact and small pellets due to rheological issues. On the other hand, optimal productivity might be associated with less dense and larger morphology. Over the years, several publications have dealt with aforementioned relations within the confines of specific organisms and products. However, contributions which evaluate such interlinkages across several fungal species are scarce. For this purpose, we are looking into methods to manipulate fungal pellet morphology in relation to individual species and products. This review attempts to address (i) how variability of pellet morphology can be assessed and (ii) how morphology is linked to productivity. Firstly, the mechanism of pellet formation is outlined. Subsequently, the description and analysis of morphological variations are discussed to finally establish interlinkages between productivity, performance and morphology across different fungal species. PMID- 29473100 TI - The suspensor as a model system to study the mechanism of cell fate specification during early embryogenesis. AB - KEY MESSAGE: The advances in the suspensor. During early embryogenesis, the proembryo consists of two domains, the embryo proper and the suspensor. Unlike the embryo proper, which has been investigated extensively, research on the suspensor has been limited in past decades. Recent studies have revealed that the suspensor plays an important role in early embryogenesis and the process of suspensor formation and degeneration may provide a unique model for studies on cell division pattern, cell fate determination, and cell death. In this review, we briefly summarize the advances in research on the suspensor, which provide new insight in our understanding of the mechanism of early embryogenesis and show great potential for a unique model for future investigations. PMID- 29473101 TI - Cardiac Function Assessments in Left Bochdalek's Hernia: Clinical Relevance. AB - The objectives of this study were to characterize peri-operative echocardiographic (ECHO) assessments of right ventricular (RV) function and pulmonary hypertension (PH) and ascertain correlation with clinical outcomes in infants with left Bochdalek's hernia (LBH). This retrospective study in a quaternary neonatal intensive care unit involved electronic database search for infants with LBH during January 2009 to July 2017. Demographics, outcomes, and ECHO parameters were accessed from archived databases. Thirty-one infants with mean gestational age and birthweight (BW) 38.4 +/- 1.4 weeks and 3079 +/- 450 g were included. Postnatal age at surgery was 4.3 +/- 2 days. Two infants died before surgery (none after surgery). The survival rate in this cohort of late preterm and term infants with LBH not accompanied by congenital heart disease was 29/31 (93.5%). PH was noted in 28 (90%). Significant changes in biventricular function and pulmonary vascular haemodynamics were noted when reassessed after surgery [RV area change (%), 28 +/- 3 vs. 34 +/- 4, p = 0.007 and pulmonary artery capacitance (PAC) (ml3 * mmHg-1), 0.05 +/- 0.03 vs. 0.09 +/- 0.05, p = 0.02]. The median duration of all respiratory support in those who were operated was 14.7 days (8.5, 25). Significant correlations were noted between pre operative ECHO assessments and the duration of respiratory support (tricuspid regurgitation, r = 0.63, p = 0.0001 and PAC, r = - 0.52, p = 0.004). Peri operative functional ECHO provided information about the evolution of cardiac function in infants with LBH.

AB - PURPOSE OF REVIEW: Type 1 diabetes (T1D) incidence in youth is growing across all racial/ethnic backgrounds, with the most marked increase in African-American youth under 5. Underrepresented racial/ethnic minorities are at an increased risk for health complications. This review focuses on the reported disparities, demographics of samples in behavioral interventions, and study design considerations. RECENT FINDINGS: Recruitment data from two ongoing behavioral intervention trials for young children with T1D are presented to compare enrolled/non-enrolled individuals and to discuss culturally appropriate study design considerations. Data were compared to the demographics of children (ages 1 6) with T1D in the clinic populations from the recruitment sites. Enrolling a representative sample and designing culturally appropriate behavioral interventions are important for generalizability, yet there is a gap between the individuals participating in T1D research and those who are most negatively affected by T1D. Suggestions are offered for ways to expand inclusion of diverse samples in behavioral intervention research in T1D. PMID- 29473104 TI - Duration of acute kidney injury in critically ill patients. AB - BACKGROUND: Duration of acute kidney injury (AKI) has been recognized a risk factor for adverse outcomes following AKI. We sought to examine the relationship of AKI duration and recurrent AKI with short-term outcomes in critically ill patients who were mechanically ventilated and met criteria for the acute respiratory distress syndrome. METHODS: Participants in the NHLBI ARDS Network SAILS multicenter trial who developed AKI were included in this analysis and divided into groups based on AKI duration. Differences in outcomes were evaluated using t test and Chi-square test. Competing risks regression and Cox regression were used to evaluate factors associated with resolving AKI and recurrent AKI. RESULTS: In total, 238 patients were included in the study. Seventy-seven patients had short duration AKI (1-2 days), 47 medium duration AKI (3-7 days), 87 persistent AKI (> 7 days) and 38 died during their AKI episode. Persistent AKI was associated with worse outcomes including increased ICU length of stay, time on the ventilator and days with cardiovascular failure. We found no clinical differences between patients with short and medium duration AKI, even when accounting for AKI severity and recurrent AKI. Patients with resolving AKI were less likely to have oliguria or moderate/severe ARDS on the day AKI criteria were met. Recurrent AKI was associated with poorer clinical outcomes. No baseline clinical factors were found to predict development of recurrent AKI. CONCLUSIONS: In critically ill patients with sepsis-associated ARDS and AKI, the impact of short and medium duration AKI on clinical outcomes was modest. Persistent and recurrent AKI were both associated with worse clinical outcomes, emphasizing the importance of identifying these patients, who may benefit from novel interventions. PMID- 29473105 TI - The use of throat packs in pediatric cleft lip/palate surgery: a retrospective study. AB - OBJECTIVES: Throat packs are commonly used to prevent ingestion or aspiration of blood and other debris during cleft lip/palate surgery. However, dislodgement or (partial) retainment after extubation could have serious consequences. The aim of the present study was to investigate the effect of omitting pharyngeal packing during cleft lip/palate surgery on the incidence of early postoperative complications in children. MATERIALS AND METHODS: A retrospective study was performed on all children who underwent cleft lip/palate surgery at the Wilhelmina Children's Hospital. This study compared the period January 2010 through December 2012 when pharyngeal packing was applied according to local protocol (group A) with the period January 2013 till December 2015 when pharyngeal packing was no longer applied after removal from the protocol (group B). Data were collected for sex, age at operation, cleft lip/palate type, type of repair, lateral incisions, length of hospital stay, and complications in the first 6 weeks after surgery. Early complications included wound dehiscence, postoperative bleeding, infection, fever, upper respiratory tract infection (URTI), and lower respiratory tract infection (LRTI). RESULTS: This study included 489 cleft lip/palate operations (group A n = 246, group B n = 243). A total of 39 (15.9%) early complications were recorded in group A and a total of 40 (16.5%) in group B. There were no significant differences (P = 0.902) in complications between the two groups; however, there was a significant difference (P < 0.001) in length of hospital stay between the two groups (group A 3.6 days vs group B 3.2 days). CONCLUSION: Omitting routine placement of throat packs in cleft lip/palate surgery was not associated with an increased early postoperative complication rate. Therefore, the traditional, routine placement of a throat pack during cleft lip/palate surgery can be questioned. CLINICAL RELEVANCE: The traditional, routine placement of a throat pack during cleft lip/palate surgery can be questioned. PMID- 29473106 TI - ATP6AP2 over-expression causes morphological alterations in the hippocampus and in hippocampus-related behaviour. AB - The (pro)renin receptor [(P)RR], also known as ATP6AP2 [ATPase 6 accessory protein 2], is highly expressed in the brain. ATP6AP2 plays a role in early brain development, adult hippocampal neurogenesis and in cognitive functions. Lack of ATP6AP2 has deleterious effects, and mutations of ATP6AP2 in humans are associated with, e.g. X-linked intellectual disability. However, little is known about the effects of over-expression of ATP6AP2 in the adult brain. We hypothesized that mice over-expressing ATP6AP2 in the brain might exhibit altered neuroanatomical features and behavioural responses. To this end, we investigated heterozygous transgenic female mice and confirmed increased levels of ATP6AP2 in the brain. Our data show that over-expression of ATP6AP2 does not affect adult hippocampal neurogenesis, exercise-induced cell proliferation, or dendritic spine densities in the hippocampus. Only a reduced ventricular volume on the gross morphological level was found. However, ATP6AP2 over-expressing mice displayed altered exploratory behaviour with respect to the hole-board and novel object recognition tests. Moreover, primary adult hippocampal neural stem cells over expressing ATP6AP2 exhibit a faster cell cycle progression and increased cell proliferation. Together, in contrast to the known deleterious effects of ATP6AP2 depletion, a moderate over-expression results in moderate behavioural changes and affects cell proliferation rate in vitro.

AB - Previous research in embodied mathematical cognition has found differences between those who start counting on their left hand and those who start counting on the right hand. However, if starting hand is a finger-embodied effect, then finger-specific interference may affect these differences between left and right starters. Furthermore, cultures that demonstrate different finger-counting habits may also be differently affected by this interference. In the current study, a total of 66 Canadians and 60 Chinese participants completed a single/dual-task paradigm and were also assessed on their starting hand for counting. The primary task was to verbally answer simple arithmetic problems, while the dual task was to either sequentially tap their fingers or their foot. Contrary to predictions, a specific finger-movement interference pattern that had previously been reported was not evident in this study, despite a much larger sample. Nevertheless, Canadians left starters outperformed right starters for every operation type, which may be further evidence of individual differences in the lateralization of arithmetic processes. Derived from a combination of a replication, a conceptual replication, and a cross-cultural comparison, this investigation suggests that embodied effects in the published literature are in need of both independent replication as well as investigation of individual differences. This study also further validates the differences between left and right starters, and suggests that more research is needed to understand the influence of embodied cognition on mathematical understanding.

AB - Disrupted somatosensory processing characterized by over- or under- responsiveness to environmental stimuli plays an important, yet often overlooked, role in typical development and is aberrant in various neurodevelopmental disorders. These dysfunctional somatosensory processes have been conceptualized as an entity termed somatosensory dysregulation (SMD). Since Tourette syndrome (TS) is a prototypical example of developmental psychopathological disorder, we hypothesised that SMD would be a feature found in children suffering from the disorder. Ninety-two subjects representing consecutive admissions to a tertiary paediatric Tourette syndrome clinic were admitted to the study. Comorbid conditions included ADHD, depression, anxiety disorder, and OCD. For purposes of the study, patients completed a battery of self-, caregiver-, and clinician-rated psychological instruments measuring TS core symptoms and comorbidities and quality of life. Sensory modulation was measured by self-report and by objective measures such as stimulation with Von Frey filaments. Almost 50% of the cohort had no SMD. Of the remainder, 14 (15%) had suspected SMD and 32 (34.8%) had SMD. SMD was significantly more common and severe when there were comorbidities. The presence of SMD was associated with more severe impairments in quality of life and less participation in daily activities. The SMD, as measured by subjective measures but not by objective, is probably more associated with central processing rather than peripheral perception. PMID- 29473113 TI - The Biocompatibility of Dental Graded Nano-Glass-Zirconia Material After Aging. AB - : ?: A graded nano-glass/zirconia (G/Z) system has been developed via the infiltration of nano-glass into a nano-zirconia surface, which is advantageous for robust core-veneer bonds. The aging issue is a key for yttrium-stabilized tetragonal zirconia polycrystals (Y-TZPs), and therefore, it is necessary to evaluate the influence of aging degradation on the biocompatibility of G/Z systems before their possible clinical application. Herein, such biocompatibility testing was performed with human gingival fibroblasts (HGFs) seeded onto unaged/aged G/Z and Y-TZP for 2-72 h. Assessments included an oral mucous membrane irritation test in conjunction with analyses of cell viability, cell adhesion, and oxidative stress responses. Significant metabolic decreases in aged G/Z- and Y-TZP-treated cells were observed at 72 h. G/Z did not elicit any significant differences in cell viability compared with Y-TZP over 72 h both before and after aging. The oxidative stress data for the aged G/Z- and Y-TZP treated cells showed a significant increase at 72 h. The G/Z specimens did not elicit any significant differences in ROS production compared with Y-TZP over 72 h both before and after aging. The cell adhesion rates of both G/Z and Y-TZP increased significantly after aging. The cell adhesion rates of G/Z and Y-TZP were not significantly different before and after aging. According to the oral mucous membrane irritation test, scores for macroscopic and microscopic observations for both the aged G/Z and unaged G/Z sides were 0, demonstrating no consequent irritation. CONCLUSIONS: The excellent biocompatibility of G/Z indicates that it has potential for future clinical applications. PMID- 29473114 TI - Treatment of post-burn and post-traumatic atrophic scars with fractional CO2 laser: experience at a tertiary care centre. AB - Scars are abnormal wound responses in predisposed individuals. They occur after any kind of wound and skin inflammation in predisposed individuals. Despite their benign nature, they can be aesthetically disabling. Although several approaches have been tried in their management, most of them have produced poor results. This study aims to assess the efficacy and safety of fractional CO2 laser treatment in the management of post-burn and post-traumatic scars. One hundred consecutive patients (77 females and 23 males) affected by post-burn scars as well as post-traumatic atrophic scars were treated with monthly sessions of fractional CO2 laser treatment. Patient's response to treatment was assessed clinically as well as improvement of scars by comparing the photographs taken before treatment with those taken 6 months after the last treatment session. Changes in skin texture, surface irregularity and pigmentation were assessed on a quartile grading scale and scored individually from 0 to 4. A mean of the three individual scores was calculated and the response was labelled as 'excellent' if the mean score achieved was > 3. A score of 2-3 was labelled as good response while a score below 1 was labelled as 'poor' response. A mean of six treatments per scar were required and all patients, followed up for 1 year after the last treatment, had optimum results and no recurrence. Response to treatment was excellent in 53.75%, good in 16.25% patients, and poor in 30% patients. Fractional CO2 laser gives a very good result in the management of patients with post-burn scars as well as post-traumatic scars with minimal adverse effects. PMID- 29473115 TI - The effects of exercise training associated with low-level laser therapy on biomarkers of adipose tissue transdifferentiation in obese women. AB - Investigations suggest the benefits of low-level laser therapy (LLLT) to improve noninvasive body contouring treatments, inflammation, insulin resistance and to reduce body fat. However, the mechanism for such potential effects in association with exercise training (ET) and possible implications in browning adiposity processes remains unclear. Forty-nine obese women were involved, aged between 20 and 40 years with a body mass index (BMI) of 30-40 kg/m2. The volunteers were divided into Phototherapy (808 nm) and SHAM groups. Interventions consisted of exercise training and phototherapy applications post exercise for 4 months, with three sessions/week. Body composition, lipid profile, insulin resistance, atrial natriuretic peptide (ANP), WNT5 signaling, interleukin-6 (IL-6), and fibroblast growth factor-21 (FGF-21) were measured. Improvements in body mass, BMI, body fat mass, lean mass, visceral fat, waist circumference, insulin, HOMA-IR, total cholesterol, LDL-cholesterol, triglycerides, and ANP in both groups were demonstrated. Only the Phototherapy group showed a reduction in interleukin-6 and an increase in WNT5 signaling. In addition, it was possible to observe a higher magnitude change for the fat mass, insulin, HOMA-IR, and FGF-21 variables in the Phototherapy group. In the present investigation, it was demonstrated that exercise training associated with LLLT promotes an improvement in body composition and inflammatory processes as previously demonstrated. The Phototherapy group especially presented positive modifications of WNT5 signaling, FGF-21, and ANP, possible biomarkers associated with browning adiposity processes. This suggests that this kind of intervention promotes results applicable in clinical practice to control obesity and related comorbidities. PMID- 29473116 TI - Phytochemical variation in treetops: causes and consequences for tree-insect herbivore interactions. AB - The interaction of plants and their herbivorous opponents has shaped the evolution of an intricate network of defences and counter-defences for millions of years. The result is an astounding diversity of phytochemicals and plant strategies to fight and survive. Trees are specifically challenged to resist the plethora of abiotic and biotic stresses due to their dimension and longevity. Here, we review the recent literature on the consequences of phytochemical variation in trees on insect-tree-herbivore interactions. We discuss the importance of genotypic and phenotypic variation in tree defence against insects and suggest some molecular mechanisms that might bring about phytochemical diversity in crowns of individual trees. PMID- 29473117 TI - Relationship among symptom clusters, quality of life, and treatment-specific optimism in patients with cancer. AB - PURPOSE: There is increasing evidence that disease and therapy-related symptoms frequently co-occur in so-called symptom clusters (SCs), which may significantly impair quality of life in patients with cancer. Although psychosocial resources may play pivotal roles in maintaining or improving quality of life, they have been neglected in SC research. Therefore, we aim to identify SCs and their relative impact on quality of life when psychosocial resources are accounted for. METHODS: Patients with cancer (n = 304) undergoing chemotherapy or chemo radiation therapy participated in a cross-sectional survey consisting of measures assessing symptoms, quality of life, resilience, treatment-specific optimism (TSO), and social support. Exploratory factor analyses and multiple regression analyses were used to identify SCs and significant explanatory variables of overall quality of life. RESULTS: Fatigue-pain, anxiety-depression, cancer therapy-related toxicity, and nausea-vomiting clusters were identified. In our final model, the fatigue-pain cluster (beta = - 0.41, p < 0.001), nausea-vomiting cluster (beta = - 0.28, p < 0.001), TSO (beta = 0.21, p < 0.001), and receiving chemo-radiation treatment (beta = - 0.11, p = 0.03) accounted for 44% of variance in overall quality of life. However, the identified SCs explained quality of life in patients with varying levels of TSO to a different extent. CONCLUSIONS: Our findings indicate that the TSO of patients may be a major factor to consider in managing SCs, because-depending on its level-different SCs and even clusters encompassing comparatively less distressing symptoms (i.e., cancer therapy related toxicities) may strongly affect quality of life.

AB - Nanocrystalline Fe2O3 thin films are deposited directly on the conduct substrates by pulsed laser deposition as anode materials for lithium-ion batteries. We demonstrate the well-designed Fe2O3 film electrodes are capable of excellent high rate performance (510 mAh g- 1 at high current density of 15,000 mA g- 1) and superior cycling stability (905 mAh g- 1 at 100 mA g- 1 after 200 cycles), which are among the best reported state-of-the-art Fe2O3 anode materials. The outstanding lithium storage performances of the as-synthesized nanocrystalline Fe2O3 film are attributed to the advanced nanostructured architecture, which not only provides fast kinetics by the shortened lithium-ion diffusion lengths but also prolongs cycling life by preventing nanosized Fe2O3 particle agglomeration. The electrochemical performance results suggest that this novel Fe2O3 thin film is a promising anode material for all-solid-state thin film batteries.

AB - In this issue of JNC, BW Spery and Coll report a retrospective analysis of 57 patients with transthyretin-related amyloidosis (ATTR) in an advanced phase of the disease who underwent 99mTechnetium-pyrophosphate (99mTcPYP) scintigraphy. Although relatively small and "negative," the study is relevant since it broadens our knowledge on the uptake of "bone tracers" in ATTR and contributes to understand the limitations of the clinical use of scintigraphy in this disease. The paper raises, directly or indirectly, at least three questions: To what extent are the different bone tracers interchangeable for the diagnosis of ATTR cardiac amyloidosis? Are bone tracers able to image non-cardiac ATTR amyloidosis? What is the explanation for the variable performance of the different bone tracers in the diagnosis of cardiac and extracardiac ATTR amyloidosis?

AB - AIMS/HYPOTHESIS: Current evidence suggests that type 2 diabetes may have a greater impact on those with earlier diagnosis (longer duration of disease), but data are limited. We examined the effect of age at diagnosis of type 2 diabetes on the risk of all-cause and cause-specific mortality over 15 years. METHODS: The data of 743,709 Australians with type 2 diabetes who were registered on the National Diabetes Services Scheme (NDSS) between 1997 and 2011 were examined. Mortality data were derived by linking the NDSS to the National Death Index. All cause mortality and mortality due to cardiovascular disease (CVD), cancer and all other causes were identified. Poisson regression was used to model mortality rates by sex, current age, age at diagnosis, diabetes duration and calendar time. RESULTS: The median age at registration on the NDSS was 60.2 years (interquartile range [IQR] 50.9-69.5) and the median follow-up was 7.2 years (IQR 3.4-11.3). The median age at diagnosis was 58.6 years (IQR 49.4-67.9). A total of 115,363 deaths occurred during 7.20 million person-years of follow-up. During the first 1.8 years after diabetes diagnosis, rates of all-cause and cancer mortality declined and CVD mortality was constant. All mortality rates increased exponentially with age. An earlier diagnosis of type 2 diabetes (longer duration of disease) was associated with a higher risk of all-cause mortality, primarily driven by CVD mortality. A 10 year earlier diagnosis (equivalent to 10 years' longer duration of diabetes) was associated with a 1.2-1.3 times increased risk of all-cause mortality and about 1.6 times increased risk of CVD mortality. The effects were similar in men and women. For mortality due to cancer (all cancers and colorectal and lung cancers), we found that earlier diagnosis of type 2 diabetes was associated with lower mortality compared with diagnosis at an older age. CONCLUSIONS/INTERPRETATION: Our findings suggest that younger-onset type 2 diabetes increases mortality risk, and that this is mainly through earlier CVD mortality. Efforts to delay the onset of type 2 diabetes might, therefore, reduce mortality.

AB - PURPOSE OF REVIEW: Chronic lymphocytic leukemia is heterogeneous disease characterized by a variable clinical course that is greatly influenced by various patient and disease characteristics. Over the last two decades, advent of new diagnostic methodologies has led to the identification of several factors of prognostic and predictive relevance. Furthermore, recent advances in next generation sequencing techniques has identified recurrent novel mutations in NOTCH1, SF3B1, BIRC3, and ATM genes whose role as prognostic and predictive markers is currently being investigated. These biologic markers carry new prognostic information and their incorporation into prognostic scoring systems will likely lead to refined multi-parameter risk models. RECENT FINDINGS: While the prognostic impact of many of the most commonly used markers on clinical outcomes in patients treated with chemo-immunotherapy is well documented, it is important to review their predictive and prognostic role in the era of novel targeted therapies. This article will discuss the currently available information on the clinical relevance of prognostic markers in patients treated with novel targeted therapies. PMID- 29473125 TI - Sulforaphane Attenuated the Pro-Inflammatory State Induced by Hydrogen Peroxide in SH-SY5Y Cells Through the Nrf2/HO-1 Signaling Pathway. AB - Sulforaphane (SFN), an isothiocyanate obtained from cruciferous vegetables, exerts antioxidant, antiapoptotic, and antitumor activities in different cell types. Moreover, SFN has been viewed as an anti-inflammatory agent. Nonetheless, the mechanism underlying the ability of SFN in modulating the immune response in mammalian cells is not completely understood yet. Therefore, we investigated here whether and how SFN would be effective in preventing inflammation induced by a pro-oxidant agent (hydrogen peroxide, H2O2) in the human neuroblastoma SH-SY5Y cells. The cells were treated with SFN at 5 MUM for 30 min before a challenge with H2O2 for an additional 24 h. Pretreatment with SFN reduced the secretion of interleukin-1beta (IL-1beta) and tumor necrosis factor-alpha (TNF-alpha), as well as decreased the levels of cyclooxygenase-2 (COX-2) in H2O2-treated cells. SFN also decreased the activity of the transcription factor nuclear factor-kappaB (NF kappaB) and the immunocontent of the p65 NF-kappaB subunit in the cell nucleus. The inhibition of heme oxygenase-1 (HO-1) by ZnPP-IX at 10 MUM or the silencing of the nuclear factor erythroid 2-related factor 2 (Nrf2) transcription factor by small interfering RNA targeting Nrf2 attenuated the anti-inflammatory and cytoprotective effects induced by SFN. Therefore, SFN exerted an anti inflammatory effect in H2O2-challenged SH-SY5Y cells by a mechanism dependent on the Nrf2/HO-1 signaling pathway.

AB - Atherosclerosis is a type of cardiovascular disease which may cause stroke. It is due to the deposition of fatty plaque in the artery walls resulting in the reduction of elasticity gradually and hence restricting the blood flow to the heart. Hence, an early prediction of carotid plaque deposition is important, as it can save lives. This paper proposes a novel data mining framework for the assessment of atherosclerosis in its early stage using ultrasound images. In this work, we are using 1353 symptomatic and 420 asymptomatic carotid plaque ultrasound images. Our proposed method classifies the symptomatic and asymptomatic carotid plaques using bidimensional empirical mode decomposition (BEMD) and entropy features. The unbalanced data samples are compensated using adaptive synthetic sampling (ADASYN), and the developed method yielded a promising accuracy of 91.43%, sensitivity of 97.26%, and specificity of 83.22% using fourteen features. Hence, the proposed method can be used as an assisting tool during the regular screening of carotid arteries in hospitals. Graphical abstract Outline for our efficient data mining framework for the characterization of symptomatic and asymptomatic carotid plaques.

AB - BACKGROUND: As the population ages, the use of primary total knee arthroplasty (TKA) is on the rise in the octogenarian population. AIMS: The objective of this study was to compare patient-reported outcomes after TKA in octogenarians versus sexagenarians. METHODS: This retrospective case-controlled comparative study with a propensity score matching analysis was conducted by 251 patients who underwent TKA for degenerative osteoarthritis of the knee. After the propensity score matching analysis, 38 octogenarians and 41 sexagenarians were identified. Range of motion (ROM), degree of flexion contracture, Charlson Comorbidity Index score, Knee Society score (KSS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores, the 36-Item Short-Form Health Survey (SF 36), postoperative complications, length of stay, and 90-day mortality after TKA were compared. The degree of improvement of each functional parameter was also assessed. RESULTS: There was no significant difference in the degree of improvement in postoperative ROM, flexion contracture, or KSS. There were only significant differences in length of hospital stay and volume of blood transfusion (p < 0.001 and p = 0.004, respectively). The octogenarian patient group showed significantly inferior outcomes for WOMAC and SF-36 score compared to the sexagenarian patient group (p = 0.009 and p = 0.022, respectively). CONCLUSION: Although the functional improvements after TKA were excellent regardless of age, TKA seemed to contribute little to quality of life in octogenarian patients. Therefore, a careful approach to improving satisfaction with subjective outcomes is needed for octogenarian patients who undergo TKA.

AB - PURPOSE: Annotation of meaningful landmark ground truth on DCE-MRI is difficult and laborious. Motion correction methods applied to DCE-MRI of the liver are thus mostly evaluated using qualitative or indirect measures. We propose a novel landmark annotation scheme that facilitates the generation of landmark ground truth on larger clinical datasets. METHODS: In our annotation scheme, landmarks are equally distributed over all time points of all available dataset cases and annotated by multiple observers on a per-pair basis. The scheme is used to annotate 26 DCE-MRI of the liver. A subset of the ground truth is used to optimize parameters of a deformable motion correction. Several variants of the motion correction are evaluated on the remaining cases with respect to distances of corresponding landmarks after registration, deformation field properties, and qualitative measures. RESULTS: A landmark ground truth on 26 cases could be generated in under 12 h per observer with a mean inter-observer distance below the mean voxel diagonal. Furthermore, the landmarks are spatially well distributed within the liver. Parameter optimization significantly improves the performance of the motion correction, and landmark distance after registration is 2 mm. Qualitative evaluation of the motion correction reflects the quantitative results. CONCLUSIONS: The annotation scheme makes a landmark-based evaluation of motion corrections for hepatic DCE-MRI practically feasible for larger clinical datasets. The comparably large number of cases enables both optimization and evaluation of motion correction methods.

AB - OBJECTIVE: To distinguish benign from malignant pulmonary nodules using CT images is critical for their precise diagnosis and treatment. A new Agile convolutional neural network (CNN) framework is proposed to conquer the challenges of a small scale medical image database and the small size of the nodules, and it improves the performance of pulmonary nodule classification using CT images. METHODS: A hybrid CNN of LeNet and AlexNet is constructed through combining the layer settings of LeNet and the parameter settings of AlexNet. A dataset with 743 CT image nodule samples is built up based on the 1018 CT scans of LIDC to train and evaluate the Agile CNN model. Through adjusting the parameters of the kernel size, learning rate, and other factors, the effect of these parameters on the performance of the CNN model is investigated, and an optimized setting of the CNN is obtained finally. RESULTS: After finely optimizing the settings of the CNN, the estimation accuracy and the area under the curve can reach 0.822 and 0.877, respectively. The accuracy of the CNN is significantly dependent on the kernel size, learning rate, training batch size, dropout, and weight initializations. The best performance is achieved when the kernel size is set to [Formula: see text], the learning rate is 0.005, the batch size is 32, and dropout and Gaussian initialization are used. CONCLUSIONS: This competitive performance demonstrates that our proposed CNN framework and the optimization strategy of the CNN parameters are suitable for pulmonary nodule classification characterized by small medical datasets and small targets. The classification model might help diagnose and treat pulmonary nodules effectively. PMID- 29473130 TI - Percutaneous endoscopic gastrostomy site infections-Incidence and risk factors. AB - BACKGROUND: Percutaneous endoscopic gastrostomy (PEG) placement is the modality of choice for long-term enteral nutrition in view of technical ease and cost effectiveness. Peristomal infection (PI) remains the most common complication following PEG tube placement. The aim of this study was to assess the incidence and risk factors for PI and outline a microbiological profile that can aid in prophylactic and therapeutic strategies. METHODS: A retrospective study of 781 patients who underwent PEG placement (Cook PEG-Pull-S-20Fr/24Fr) from 2010 to 2015 at our tertiary care center were included. Relevant data were collected from the hospital electronic medical records. The incidence of PI was computed and potential risk factors were assessed using univariate analysis. The microbiological profile was created along with sensitivity patterns after reviewing the culture reports. Statistical analysis was performed using SPSS version 20.0. RESULTS: PEG tube placement was performed in 781 patients (mean age 55.9 +/- 36.1; M:F = 2:75). The major indication was oropharyngeal malignancies. PI was seen in 171 patients (21.9%). Diabetes mellitus, duration of hospital stay more than 7 days, and hypoalbuminemia were found to be significant risk factors for the development of PI (p < 0.05). Patients who had chemotherapy or radiotherapy before PEG placement had a higher incidence of peristomal infections (p 0.00). Pseudomonas and Klebsiella were the most common organisms causing infection. CONCLUSIONS: PI remains a significant complication of PEG placement. Pseudomonas and Klebsiella are the most common organisms and prophylactic antibiotic protocols should be tailored accordingly. Elective PEG before the institution of chemotherapy/radiotherapy in patients with oropharyngeal malignancies is recommended. PMID- 29473131 TI - Searching for new drugs for Chagas diseases: triazole analogs display high in vitro activity against Trypanosoma cruzi and low toxicity toward mammalian cells. AB - Chagas disease is one of the most relevant endemic diseases in Latin America caused by the flagellate protozoan Trypanosoma cruzi. Nifurtimox and benzonidazole are the drugs used in the treatment of this disease, but they commonly are toxic and present severe side effects. New effective molecules, without collateral effects, has promoted the investigation to develop new lead compounds with to advance for clinical trials. Previously, 3-nitro-1H-1,2,4 triazole-based amines and 1,2,3-triazoles demonstrated significant trypanocidal activity against T. cruzi. In this paper, we synthesized a new series of 92 examples of 1,2,3-triazoles. Six compounds exhibited antiparasitic activity, 14, 25, 27, 31 and 40, 43 and were effective against epimastigotes of two strains of T. cruzi (Y and Dm28-C) and 25, 27 and 31 exhibited trypanocidal activity similar to benzonidazole. Notably, the compound 25 compared to benzonidazole increase the toxicity against T. cruzi, with no apparent toxicity to the cell line of mice macrophages or primary mice peritoneal macrophages. As results, we calculated selectivity indexes up to 2000 to 25 and 31 in both T. cruzi strains. Derivative 14 caused a trypanostatic effect because it did not damage external epimastigote membrane. Triazoles 40 and 43 impaired parasites viability using a pathway not dependent on ROS production. PMID- 29473132 TI - Error-prone PCR mutagenesis and reverse bacterial two-hybrid screening identify a mutation in asparagine 53 of the Staphylococcus aureus ESAT6-like component EsxB that perturbs interaction with EsxD. AB - The ESAT6-like Secretion System (ESS) of the human pathogen Staphylococcus aureus secretes heterodimeric virulence effectors such as EsxB and EsxD. To gain insights into the nature of EsxB-EsxD interaction, randomly mutated esxB generated by error-prone PCR was co-transformed together with esxD as adenylate cyclase fusion constructs into cyclase-deficient Escherichia coli, followed by reverse bacterial two-hybrid screening. Three color species were observed: dark blue, light blue, and white (no EsxB-EsxD interaction). The esxB from white colonies was subjected to standard PCR to check for gene signal, followed by SDS PAGE for variant stability assessment. The gene coding for a stable EsxB variant that perturbed interaction with EsxD was further subjected to DNA sequencing. A single point mutation in esxB at position 157 was identified, leading to an amino acid change from asparagine to aspartic acid at position 53 in the resulting protein. Structural modeling of EsxB reveals that N53 is surface exposed. Whereas N53S substitution by site-directed mutagenesis retained heterodimerization with EsxD, N53A substitution abrogated such interaction. In addition, N53D change in EsxB did not alter interaction with EssG, another soluble component of the ESS pathway, suggesting minimal impact of the N53D substitution on EsxB stability and solubility. Taken together, these data provide new insights into the nature of EsxB-EsxD interaction and offer a systematic approach for in vivo analysis of protein-protein interactions of pathogenic bacteria in non-pathogenic hosts. PMID- 29473133 TI - Self-Assessment of Teaching Skills Among Psychiatric Residents. AB - OBJECTIVE: Psychiatry residency programs have increasingly emphasized the role of resident-as-teacher; however, little is known about resident self-perceptions of teaching skills. This study reports on psychiatry residents' self-perceived skills in teaching medical students and compares cohort ratings with anonymous medical student evaluations of residents as teachers at our large academic residency program. METHODS: In May-June 2016, 84 residents in our program were surveyed using an anonymous, web-based survey, and this data was then compared to 3 years of aggregate data from anonymous student evaluations of resident teaching at our institution. RESULTS: Forty-seven (47) residents responded to the survey (56% response rate). Residents reported self-perceived deficits in several specific teaching competencies. Medical students consistently rated residents higher with respect to teaching skills than residents rated themselves, and these data were highly statistically significant. CONCLUSION: This study underscores the benefits of resident self-assessment in comparison to medical student evaluations of residents as teachers and this information can be used to inform training programs' resident-as-teacher curricula.

AB - Objectives Studies suggest that parents tend to misperceive their child's actual weight status and typically underestimate their child's weight. Since few studies examine the factors that influence parental misperception, this study aims to assess the influence of parent and child factors with parental misperception of their child's actual weight status who were either at their recommended weight or overweight/obese in South Carolina in 2013 and 2014. Methods Secondary data were obtained from the Behavioral Risk Factor Surveillance System (BRFSS) and the Children's Health Assessment Survey (CHAS) in 2013 and 2014 in SC. Parental misperception of child's actual weight status was measured by comparing parental perception to their child's actual weightstatus measured via BMI. Logistic regression was conducted to assess the association between parental and child factors with parental misperception of child's weight status. Results In the adjusted multivariate analysis, only child's age was significantly and positively associated with parental misperception of their child's actual weight status. Conclusions for Practice This cross sectional analysis showed an association between child's age and parental misperception of child's actual weight status. It is essential to educate parents about their children's weight status, especially among young children. PMID- 29473135 TI - Immunomodulatory Effects of CP-25 on Splenic T Cells of Rats with Adjuvant Arthritis. AB - Rheumatoid arthritis (RA) is an autoimmune disease in which T cells play an important role. Paeoniflorin-6-oxy-benzenesulfonate (CP-25) shows a strong anti inflammatory and immunomodulatory effect in the joint of adjuvant arthritis (AA) rats, but the role of the spleen function is still unclear. The aim of this study was to research how CP-25 regulated spleen function of AA rats. Male Sprague Dawley rats were administered with CP-25 (50 mg/kg) orally from day 17 to 29 after immunization. The spleen histopathological changes were analyzed by hematoxylin-eosin staining. G protein-coupled receptor kinases (GRKs) and prostaglandin receptor subtypes (EPs) were screened by Western blot and immunohistochemistry. The co-expression of GRK2 and EP2 as well as GRK2 and EP4 was measured by immunofluorescence and co-immunoprecipitation. The expression of GRK2 and EP4 in splenic T cells was further detected by immunofluorescence. CP-25 was found to relieve the secondary paw swelling, attenuate histopathologic changes, and downregulate GRK2, EP2 and EP4 expression in AA rats. Additionally, CP-25 not only downregulated the co-expression of GRK2 and EP4 but also downregulated GRK2, EP4 expression in splenic T cells of AA rats. From these results, we can infer that CP-25 play an anti-inflammatory and immune function by affecting the function of the splenic T cells. PMID- 29473137 TI - Assessing associations between indoor environment and health symptoms in Romanian school children: an analysis of data from the SINPHONIE project. AB - School environment may have an impact on children's health, but few studies have focused on indoor comfort factors such as temperature, humidity, and noise in relation with potential effects on children's health. Our cross-sectional study used data from the European Schools Indoor Pollution and Health Observatory Network in Europe (SINPHONIE) project to assess children's allergy, asthma-like symptoms, and flu-like symptoms in relation with classroom comfort and environmental factors. The study used self-reported data from three questionnaires to identify classroom conditions and student health outcomes for 280 students. We used backwards variable selection and unconditional logistic regression to assess the outcome-environment relationship while controlling for demographics, family history of allergy, and home exposures. We found increased risks for allergy and flu-like symptoms associated with hot classrooms in the heating season, increased risks for asthma-like symptoms associated with noisy classrooms, and a protective effect for allergy associated with good outdoor air quality. Romanian classrooms rely on natural ventilation, which may contribute to increased temperature and humidity in the heating season. Further research warrants the use of SINPHONIE's measurement data to validate our findings. PMID- 29473138 TI - Family environmental and dietary implications for low-level prenatal lead exposure in Wujiang City, China. AB - To explore the potential environmental and dietary factors during pregnancy affecting low-level prenatal lead exposure, we conducted a longitudinal study in Wujiang City, China. A total of 1976 mother-infant pairs were included from 2009 to 2010. An interviewed questionnaire was conducted and cord blood samples were collected. The geometric means of cord blood lead level was 30.3 MUg/L (95% CI, 29.8-30.8) with 99.24% below 100 MUg/L. Maternal age, passive smoking, and living in the countryside were significantly associated with cord blood lead concentrations. Multiple logistic models showed that some family environmental factors including using firewood and electricity as kitchen fuel were positively correlated with increased cord blood lead levels. Among dietary sources recorded in this study, meat consumption (> 3 times/week), fish consumption (1-3 times/week), vegetables consumption (> 1 times/day), and fruit intake (> 1 times/day) had inverse relationship with cord blood lead levels. In general, our findings may have important implications for family environmental and dietary direction during pregnancy to decrease prenatal lead exposure. PMID- 29473140 TI - Variance of the global signal as a pretreatment predictor of antidepressant treatment response in drug-naive major depressive disorder. AB - Several behavioral and neuroimaging markers could be used to predict eventual antidepressant medication (ADM) outcomes in patients with major depressive disorder (MDD). However, these predictors are either subjective or complex, which has limited their clinical use. Thus, we aimed to identify an objective and easy to-get marker to predict early therapeutic efficacy. Forty-seven drug-naive patients with MDD and 47 age-, gender- and education-matched healthy controls underwent resting-state functional magnetic resonance imaging (fMRI) scans. We calculated the variable coefficient (VC) of the global signal for each subject. Baseline Hamilton Rating Scale for Depression (HRSD) score and that after 2 weeks of ADM were assessed for patients. Although there was no difference in VC between patients with MDD and healthy controls, we found a significant positive correlation between the VC and the decline rate of HRSD scores in the patients. Compared with the non-responding depression (NRD) group, the treatment-responsive depression (TRD) group had a higher VC. Receiver operator characteristic curve analysis revealed that the VC exhibited a good ability to differentiate TRD from NRD. In addition, the linear and logistic regression analyses showed that the VC was a significant predictor of the decline rate of HRSD scores and the antidepressant treatment response. These findings suggest that variance of the global signal may serve as a useful marker to help clinicians find an appropriate drug for individuals with MDD at the earliest opportunity and then further to facilitate personalized therapy. PMID- 29473139 TI - Effects of soil pyrene contamination on growth and phenolics in Norway spruce (Picea abies) are modified by elevated temperature and CO2. AB - With the constant accumulation of polycyclic aromatic hydrocarbons (PAHs) in soil and increasing temperature and CO2 levels, plants will inevitably be exposed to combined stress. Studies on the effects of such combined stresses are needed to develop mitigation and adaptation measures. Here, we investigated the effects of soil pyrene contamination (50 mg kg-1) on growth and phenolics of 1-year-old Norway spruce seedlings from five different origins in Finland at elevated temperature (+ 2 degrees C) and CO2 (+ 360 ppm). Pyrene significantly decreased spruce height growth (0-48%), needle biomass (0-44%), stem biomass (0-43%), and total phenolic concentrations in needles (2-13%) and stems (1-19%) compared to control plants. Elevated temperature alone did not affect growth but led to lower concentrations of total phenolics in needles (5-29%) and stems (5-18%) in both soil treatments. By contrast, elevated CO2 led to higher needle biomass (0-39%) in pyrene-spiked soils and higher concentrations of stem phenolics (0-18%) in pyrene-spiked and control soils compared to ambient treatments. The decrease in height growth and phenolic concentrations caused by pyrene was greater at elevated temperature, while elevated CO2 only marginally modified the response. Seedlings from different origins showed different responses to the combined environmental stressors. The changes in growth and in the quantity and quality of phenolics in this study suggest that future climate changes will aggravate the negative influence of soil pyrene pollution on northern conifer forest ecosystems. PMID- 29473142 TI - Visually induced gains in pitch discrimination: Linking audio-visual processing with auditory abilities. AB - Perception is fundamentally a multisensory experience. The principle of inverse effectiveness (PoIE) states how the multisensory gain is maximal when responses to the unisensory constituents of the stimuli are weak. It is one of the basic principles underlying multisensory processing of spatiotemporally corresponding crossmodal stimuli that are well established at behavioral as well as neural levels. It is not yet clear, however, how modality-specific stimulus features influence discrimination of subtle changes in a crossmodally corresponding feature belonging to another modality. Here, we tested the hypothesis that reliance on visual cues to pitch discrimination follow the PoIE at the interindividual level (i.e., varies with varying levels of auditory-only pitch discrimination abilities). Using an oddball pitch discrimination task, we measured the effect of varying visually perceived vertical position in participants exhibiting a wide range of pitch discrimination abilities (i.e., musicians and nonmusicians). Visual cues significantly enhanced pitch discrimination as measured by the sensitivity index d', and more so in the crossmodally congruent than incongruent condition. The magnitude of gain caused by compatible visual cues was associated with individual pitch discrimination thresholds, as predicted by the PoIE. This was not the case for the magnitude of the congruence effect, which was unrelated to individual pitch discrimination thresholds, indicating that the pitch-height association is robust to variations in auditory skills. Our findings shed light on individual differences in multisensory processing by suggesting that relevant multisensory information that crucially aids some perceivers' performance may be of less importance to others, depending on their unisensory abilities. PMID- 29473141 TI - The Trypanosoma cruzi RNA-binding protein RBP42 is expressed in the cytoplasm throughout the life cycle of the parasite. AB - Trypanosoma cruzi, the protozoan parasite that causes Chagas disease in humans, has a complex life cycle that promotes survival in disparate environments. In each environment, the parasite must fine-tune its metabolic pathways to divide and multiply. In the absence of recognizable transcriptional gene regulation, it is apparent that protein levels are determined by post-transcriptional mechanisms. Post-transcriptional gene control is influenced by RNA-binding proteins that target mRNAs in the cell's cytoplasm. To initiate the study of post transcriptional activities in T. cruzi, we studied this organism's ortholog of RBP42, a trypanosomal RNA-binding protein. RBP42 was originally detected in Trypanosoma brucei and was shown to target a subset of mRNAs that encode proteins governing central carbon metabolism. T. cruzi RBP42 structurally resembles T. brucei RBP42, sharing an NTF2 domain at its amino terminus and a single RNA binding domain (specifically, the RNA recognition motif, or RRM), at its carboxy terminus. A phylogenetic analysis reveals that an NTF2 and a single RRM are distinguishing features of all RBP42 orthologs within the broad kinetoplastid grouping. T. cruzi RBP42 is expressed in all life cycle stages of the parasite as determined by immunoblot and immunofluorescence microscopy. In each case, the protein is localized to the cytoplasm, indicating a role for T. cruzi RBP42 in post-transcriptional activities in all stages of the parasite life cycle. We speculate that RBP42 influences the dynamic metabolic pathways responsible for parasite infection and transmission. PMID- 29473143 TI - Emotionally conditioning the target-speech voice enhances recognition of the target speech under "cocktail-party" listening conditions. AB - Under a noisy "cocktail-party" listening condition with multiple people talking, listeners can use various perceptual/cognitive unmasking cues to improve recognition of the target speech against informational speech-on-speech masking. One potential unmasking cue is the emotion expressed in a speech voice, by means of certain acoustical features. However, it was unclear whether emotionally conditioning a target-speech voice that has none of the typical acoustical features of emotions (i.e., an emotionally neutral voice) can be used by listeners for enhancing target-speech recognition under speech-on-speech masking conditions. In this study we examined the recognition of target speech against a two-talker speech masker both before and after the emotionally neutral target voice was paired with a loud female screaming sound that has a marked negative emotional valence. The results showed that recognition of the target speech (especially the first keyword in a target sentence) was significantly improved by emotionally conditioning the target speaker's voice. Moreover, the emotional unmasking effect was independent of the unmasking effect of the perceived spatial separation between the target speech and the masker. Also, (skin conductance) electrodermal responses became stronger after emotional learning when the target speech and masker were perceptually co-located, suggesting an increase of listening efforts when the target speech was informationally masked. These results indicate that emotionally conditioning the target speaker's voice does not change the acoustical parameters of the target-speech stimuli, but the emotionally conditioned vocal features can be used as cues for unmasking target speech. PMID- 29473145 TI - Considerations for Developing Targeted Therapies in Low-Frequency Molecular Subsets of a Disease. AB - Advances in our understanding of the molecular underpinnings of disease have spurred the development of targeted therapies and the use of precision medicine approaches in patient care. While targeted therapies have improved our capability to provide effective treatments to patients, they also present additional challenges to drug development and benefit-risk assessment such as identifying the subset(s) of patients likely to respond to the drug, assessing heterogeneity in response across molecular subsets of a disease, and developing diagnostic tests to identify patients for treatment. These challenges are particularly difficult to address when targeted therapies are developed to treat diseases with multiple molecular subtypes that occur at low frequencies. To help address these challenges, the US Food and Drug Administration recently published a draft guidance entitled "Developing Targeted Therapies in Low-Frequency Molecular Subsets of a Disease." Here we provide additional information on specific aspects of targeted therapy development in diseases with low-frequency molecular subsets. PMID- 29473144 TI - Speaker information affects false recognition of unstudied lexical-semantic associates. AB - Recognition of and memory for a spoken word can be facilitated by a prior presentation of that word spoken by the same talker. However, it is less clear whether this speaker congruency advantage generalizes to facilitate recognition of unheard related words. The present investigation employed a false memory paradigm to examine whether information about a speaker's identity in items heard by listeners could influence the recognition of novel items (critical intruders) phonologically or semantically related to the studied items. In Experiment 1, false recognition of semantically associated critical intruders was sensitive to speaker information, though only when subjects attended to talker identity during encoding. Results from Experiment 2 also provide some evidence that talker information affects the false recognition of critical intruders. Taken together, the present findings indicate that indexical information is able to contact the lexical-semantic network to affect the processing of unheard words. PMID- 29473146 TI - Perceptual experience shapes our ability to categorize faces by national origin: A new other-race effect. AB - People are better at recognizing own-race than other-race faces. This other-race effect has been argued to be the result of perceptual expertise, whereby face specific perceptual mechanisms are tuned through experience. We designed new tasks to determine whether other-race effects extend to categorizing faces by national origin. We began by selecting sets of face stimuli for these tasks that are typical in appearance for each of six nations (three Caucasian, three Asian) according to people from those nations (Study 1). Caucasian and Asian participants then categorized these faces by national origin (Study 2). Own-race faces were categorized more accurately than other-race faces. In contrast, Asian American participants, with more extensive other-race experience than the first Asian group, categorized other-race faces better than own-race faces, demonstrating a reversal of the other-race effect. Therefore, other-race effects extend to the ability to categorize faces by national origin, but only if participants have greater perceptual experience with own-race, than other-race faces. Study 3 ruled out non-perceptual accounts by showing that Caucasian and Asian faces were sorted more accurately by own-race than other-race participants, even in a sorting task without any explicit labelling required. Together, our results demonstrate a new other-race effect in sensitivity to national origin of faces that is linked to perceptual expertise. PMID- 29473147 TI - Agency and responsibility in adolescent students: A challenge for the societies of tomorrow. AB - BACKGROUND: The literature in educational psychology converges on the idea that students should take an active and accountable position in their learning processes. Nevertheless, there is still a lack of research that has systematically put the constructs of agency and responsibility at the core of their interests. AIMS: In this study, we explore whether good experiences at school - here conceptualized as the general level of basic needs fulfilment and interpersonal justice - impact on student agency and responsibility, which in turn are considered as possible mediators between a good educational experience and two outcome measures, that is, academic achievement and career decision making self-efficacy. PARTICIPANTS: The study was held on a sample of 911 high school students equally distributed between males and females. METHOD: Data were collected through the use of a questionnaire comprising six measures assessing students' basic psychological need fulfilment, interpersonal justice, agentic engagement, responsibility for learning, academic achievement, and career decision-making self-efficacy. RESULTS AND CONCLUSIONS: Structural equation modelling indicated that basic needs fulfilment positively predicts agency, responsibility, academic achievement, and career decision-making self-efficacy. Interpersonal justice positively predicts responsibility. The indirect effect from basic psychological needs on career decision-making self-efficacy through the mediating effects of student agentic engagement and student responsibility was significant. The indirect effect from interpersonal justice on career decision-making self-efficacy through the mediating effect of student responsibility for learning was significant. These results are commented at the light of their implications for teacher practices, as they emphasize the importance of good experiences at school for promoting in students an active civic sense and a greater accountability. PMID- 29473148 TI - A subset of patients with pemphigoid (herpes) gestationis has serological evidence of celiac disease. AB - BACKGROUND: Pemphigoid (herpes) gestationis (PG) is an uncommon, self-limited disease with other autoimmune associations; however, celiac disease (CD) is not recognized as one. METHODS: From 71 patients' sera submitted for herpes gestationis factor (HGF) testing over a 5-year period, 12 were consistent with PG demonstrating HGF and increased IgG BP180 antibody levels; these sera were tested for IgA and IgG endomysial antibodies (EMA), epithelial basement membrane zone and cell surface antibodies by indirect immunofluorescence, and for IgA and IgG tissue transglutaminase (transglutaminase 2 or TG2) antibodies, IgA epidermal transglutaminase (transglutaminase 3 or TG3) antibodies, IgG BP230, and IgG desmoglein 1 and desmoglein 3 antibodies by enzyme-linked immunosorbent assays (ELISAs). RESULTS: Three of 12 patients' sera with PG (25%) had CD antibodies with positive IgA EMA and increased IgA TG2 antibody levels; two of these had positive IgG EMA, and one other had an increased IgA TG3 antibody level. CONCLUSIONS: A subset of patients with serological findings of PG also has serological evidence of CD, which may have implications in the etiopathogenesis of PG and which reveals important information about the mother's, and possibly her infant's, health.

AB - This issue of Clinical Pharmacology & Therapeutics (CPT) includes the Clinical Pharmacogenetics Implementation Consortium (CPIC) guideline for using CYP2D6 genotyping to guide tamoxifen therapy for breast cancer patients. CYP2D6 metabolizes tamoxifen to its more active metabolite, endoxifen, and patients with reduced CYP2D6 activity have reduced circulating endoxifen concentrations. In this associated commentary, we recognize and honor the late Dr. David Flockhart, who began the research and made early fundamental discoveries on tamoxifen that have now resulted in this guideline. PMID- 29473151 TI - Couples' Perceptions of Each Other's Daily Affect: Empathic Accuracy, Assumed Similarity, and Indirect Accuracy. AB - This study examined couples' perceptions of each other's daily affect, using a daily diary methodology. Specifically, we tested the extent to which couples accurately inferred how their partner was feeling (empathic accuracy) and the extent to which spouses used their own feelings as a gauge for how their partner was feeling (assumed similarity). We also tested for indirect accuracy in couples' perceptions; that is, that assumed similarity in the context of actual similarity leads to empathic accuracy. Participants were 51 couples who completed daily diaries for seven consecutive nights. Results based on the Actor-Partner Interdependence Model indicated that couples showed both empathic accuracy and assumed similarity in their perception of their partner's positive affect; however, they used assumed similarity in rating their partner's hard negative (anger, hostility) and soft negative (sadness, fear) affect. Furthermore, tests of indirect accuracy found that wives were indirectly accurate in perceiving their husbands' positive affect and both husbands and wives were indirectly accurate in perceiving each other's hard negative affect because they were biased. Complementing laboratory studies, the present study highlights that examining couples' perceptions of each other's feelings in contexts of daily life, and differentiating positive and negative emotions, can further our understanding of the role of emotions for healthy relationship functioning. PMID- 29473150 TI - Better outcomes of modified myeloablative conditioning without antithymocyte globulin versus myeloablative conditioning in cord blood transplantation for hematological malignancies: A retrospective (development) and a prospective (validation) study. AB - Cord blood transplantation (CBT) is an effective option for treating hematological malignancies, but graft failure (GF) remains the primary cause of therapy failure. Thus, based on myeloablative conditioning (MAC) of busulfan with cyclophosphamide (Bu/Cy) or total body irradiation with Cy (TBI/Cy), fludarabine (Flu) was added to Bu/Cy and cytarabine (CA) to TBI/Cy for a modified myeloablative conditioning (MMAC). To compare the prognosis of MMAC with MAC, we conducted a retrospective study including 58 patients who underwent CBT with MAC or MMAC from 2000 to 2011. Neutrophil and platelet engraftment rate, overall survival (OS) and disease free survival (DFS) were significantly higher in the MMAC group (adjusted hazard ratio [HR], 2.58, 2.43, 0.36 and 0.37; p < 0.01, p = 0.01, p = 0.02 and p = 0.02, separately). Nonrelapse mortality (NRM) was comparable (p = 0.183). To validate the outcomes noted in the MMAC group, we conducted a prospective single-arm clinical trial including 188 patients who underwent CBT with MMAC from 2011 to 2015. Engraftment rate, survival and NRM of the MMAC group in the prospective trail (MMAC-P) were similar to the MMAC group in the retrospective study (MMAC-R). This study is the first to demonstrate the superiority of MMAC to MAC in CBT for hematological malignancies. PMID- 29473152 TI - White matter spongiosis with vigabatrin therapy for infantile spasms. AB - The histopathology, "white matter spongiosis," defined by electron microscopy (EM) as "intramyelinic edema," has been associated with vigabatrin therapy in various animal models, but its role or significance in clinical studies is unknown. We conducted a neuropathological examination on a 27-month-old boy with bilateral polymicrogyria and epilepsy after sudden unexpected death in epilepsy (SUDEP). The patient was initiated on vigabatrin at 4 months of age, which controlled infantile spasms, and was continued as maintenance therapy. Autopsy showed a combination of developmental and acquired lesions: (1) bilateral gyral malformations of the frontal, parietal, temporal, and insular cortex; (2) agenesis of the olfactory tracts and bulbs; (3) hippocampal abnormalities: dentate gyrus bilamination and granule cell dispersion; and (4) areas of microscopic bilateral, symmetric white matter spongiosis in the brainstem central tegmental tract, amiculum and hilum of the inferior olive, medial longitudinal fasciculus, paragigantocellularis lateralis, optic nerves and chiasm, and hypothalamus. The white matter spongiosis was identical to the histopathologic lesions (which by EM exhibited intramyelinic edema) that were demonstrated in animal models on vigabatrin therapy, indicating that vigabatrin toxicity is not restricted to animal models. PMID- 29473154 TI - Polyunsaturated fatty acids and risk of melanoma: A Mendelian randomisation analysis. AB - Melanoma is the deadliest form of skin cancer, mainly affecting populations of European ancestry. Some observational studies suggest that particular diets reduce melanoma risk, putatively through an increase in polyunsaturated fatty acid (PUFA) consumption. However, interpretation of these observational findings is difficult due to residual confounding or reverse causality. To date, a randomized controlled trial has not been carried out to examine the relationship between PUFAs and melanoma. Hence, we performed a Mendelian randomisation (MR) study to evaluate the link between PUFAs and melanoma. To perform MR, we used summary results from the largest risk genome-wide association study (GWAS) meta analysis of melanoma, consisting of 12,874 cases and 23,203 controls. As instrumental variables we selected SNPs associated with PUFA levels from a GWAS meta-analysis of PUFA levels, from the CHARGE consortium. We used the inverse variance weighted method to estimate a causal odds ratio. To aid interpretation, we established a benchmark "large" predicted change in PUFAs in which, for example, an increase in docosahexaenoic acid (DPA) of 0.17 units (equal to 1 standard deviation) moves a person from the 17th percentile to the median. Raising PUFA levels by a large amount (increasing DPA by 0.17 units) only negligibly changed melanoma risk: odds ratio [OR] = 1.03 (95% confidence interval [CI] = 0.96-1.10). Other PUFAs yielded similar results as DPA. Our MR analysis suggests that the effect of PUFA levels on melanoma risk is either zero or very small.

Komen Tissue Bank. AB - Lesser degrees of terminal duct lobular unit (TDLU) involution, as reflected by higher numbers of TDLUs and acini/TDLU, are associated with elevated breast cancer risk. In rodent models, the insulin-like growth factor (IGF) system regulates involution of the mammary gland. We examined associations of circulating IGF measures with TDLU involution in normal breast tissues among women without precancerous lesions. Among 715 Caucasian and 283 African American (AA) women who donated normal breast tissue samples to the Komen Tissue Bank between 2009 and 2012 (75% premenopausal), serum concentrations of IGF-I and binding protein (IGFBP)-3 were quantified using enzyme-linked immunosorbent assay. Hematoxilyn and eosin-stained tissue sections were assessed for numbers of TDLUs ("TDLU count"). Zero-inflated Poisson regression models with a robust variance estimator were used to estimate relative risks (RRs) for association of IGF measures (tertiles) with TDLU count by race and menopausal status, adjusting for potential confounders. AA (vs. Caucasian) women had higher age-adjusted mean levels of serum IGF-I (137 vs. 131 ng/mL, p = 0.07) and lower levels of IGFBP-3 (4165 vs. 4684 ng/mL, p < 0.0001). Postmenopausal IGFBP-3 was inversely associated with TDLU count among AA (RRT3vs.T1 = 0.49, 95% CI = 0.28-0.84, p trend = 0.04) and Caucasian (RRT3vs.T1 =0.64, 95% CI = 0.42-0.98, p-trend = 0.04) women. In premenopausal women, higher IGF-I:IGFBP-3 ratios were associated with higher TDLU count in Caucasian (RRT3vs.T1 =1.33, 95% CI = 1.02-1.75, p-trend = 0.04), but not in AA (RRT3vs.T1 =0.65, 95% CI = 0.42-1.00, p-trend = 0.05), women. Our data suggest a role of the IGF system, particularly IGFBP-3, in TDLU involution of the normal breast, a breast cancer risk factor, among Caucasian and AA women. PMID- 29473155 TI - Stiripentol efficacy and safety in Dravet syndrome: a 12-year observational study. AB - AIM: To assess long-term safety and efficacy of stiripentol as an antiepileptic medication for people with Dravet syndrome. METHOD: A prospective, observational open-label study (2003-2015) of the efficacy and long-term safety of stiripentol in patients with Dravet syndrome and ongoing seizures. Frequency of generalized tonic-clonic seizures, focal seizures, status epilepticus, and adverse events were recorded. RESULTS: Forty-one patients started stiripentol, with median age at enrolment 5 years 7 months (range 11mo-22y) and median duration of treatment 37 months (range 2-141mo). Twenty out of 41 patients had greater than or equal to 50% long-term reduction in frequency of generalized tonic-clonic seizures. Frequency of focal seizures was decreased by greater than or equal to 50% in 11 out of 23 patients over the long-term. Frequency of status epilepticus was decreased by 50% or more in 11 out of 26 patients. The most common adverse events were anorexia, weight loss, sedation, and behavioural changes. One patient had worsening of absence and myoclonic seizures. Another developed recurrent pancreatitis on concurrent valproate. INTERPRETATION: Stiripentol improves long term seizure frequency in approximately 50% of patients with Dravet syndrome, when used as part of unrestricted polytherapy. Long-term use appears safe. In more than 40% of patients, episodes of status epilepticus markedly decrease after stiripentol initiation. What this paper adds Frequency of status epilepticus is reduced in 40% of patients with Dravet syndrome after stiripentol initiation. Stiripentol is effective for generalized tonic-clonic and focal seizures. Stiripentol can be safely used with a range of antiepileptic drugs. PMID- 29473156 TI - New Evidence on Employment Effects of Informal Care Provision in Europe. AB - OBJECTIVE: To estimate how labor force participation is affected when adult children provide informal care to their parents. DATA SOURCE: Survey of Health, Ageing and Retirement in Europe from 2004 to 2013. STUDY DESIGN: To offset the problem of endogeneity, we exploit the availability of other potential caregivers within the family as predictors of the probability to provide care for a dependent parent. Contrary to most previous studies, the dataset covers the whole working-age population in the majority of European countries. Individuals explicitly had to opt for or against the provision of care to their care dependent parents, which allows us to more precisely estimate the effect of caregiving on labor force participation. PRINCIPAL FINDINGS: Results reveal a negative causal effect that indicates that informal care provision reduces labor force participation by 14.0 percentage points (95 percent CI: -0.307, 0.026). Point estimates suggest that the effect is larger for men; however, this gender difference is not significantly different from zero at conventional levels. CONCLUSIONS: Results apply to individuals whose consideration in long-term care policy is highly relevant, that is, children whose willingness to provide informal care to their parents is altered by available alternatives of family caregivers.

AB - Spinal muscular atrophy (SMA), an autosomal recessive disease caused by a decrease in levels of the survival motor neuron (SMN) protein, is the most common genetic cause of infant mortality. Although neuromuscular pathology is the most severe feature of SMA, other organs and tissues, including the heart, are also known to be affected in both patients and animal models. Here, we provide new insights into changes occurring in the heart, predominantly at pre- and early symptomatic ages, in the Taiwanese mouse model of severe SMA. Thinning of the interventricular septum and dilation of the ventricles occurred at pre- and early symptomatic ages. However, the left ventricular wall was significantly thinner in SMA mice from birth, occurring prior to any overt neuromuscular symptoms. Alterations in collagen IV protein from birth indicated changes to the basement membrane and contributed to the abnormal arrangement of cardiomyocytes in SMA hearts. This raises the possibility that developmental defects, occurring prenatally, may contribute to cardiac pathology in SMA. In addition, cardiomyocytes in SMA hearts exhibited oxidative stress at pre-symptomatic ages and increased apoptosis during early symptomatic stages of disease. Heart microvasculature was similarly decreased at an early symptomatic age, likely contributing to the oxidative stress and apoptosis phenotypes observed. Finally, an increased incidence of blood retention in SMA hearts post-fixation suggests the likelihood of functional defects, resulting in blood pooling. These pathologies mirror dilated cardiomyopathy, with clear consequences for heart function that would likely contribute to potential heart failure. Our findings add significant additional experimental evidence in support of the requirement to develop systemic therapies for SMA capable of treating non-neuromuscular pathologies. PMID- 29473160 TI - Deciphering the roles of FOXO1 in human neoplasms. AB - Neoplasms constituted an enormous burden and contributed to an estimated 8.2 million deaths in 2012 worldwide. FOXO1 (forkhead box O1), a member of the forkhead box (FOX) family, is a transcriptional factor involved in diverse cellular functions. Herein, we concentrate on recent studies of the antineoplastic roles of FOXO1 in neoplasms. This article may serve as a guide for future research and identify FOXO1 as a potent therapeutic target in neoplasms. PMID- 29473161 TI - Depressive Symptoms, Criticism, and Counter-Criticism in Marital Interactions. AB - Although people with depressive symptoms face criticism, hostility, and rejection in their close relationships, we do not know how they respond. Following interpersonal theories of depression, it might be expected that depressive symptoms would be associated with a tendency to receive and also to express criticism toward one's spouse, and that at least some of this criticism would be a contingent response to criticism received (i.e., "counter-criticism"). However, other research has determined that depressive symptoms/behaviors suppress partner criticism, suggesting that depressed people might respond to partner criticism similarly, by subsequently expressing less criticism. In a sample of 112 married couples, partial correlations, regressions, and Actor-Partner Interdependence Modeling indicated that lower criticism and counter-criticism expression during a laboratory marital interaction task was associated with higher depressive symptoms, especially when such individuals were clinically depressed. Furthermore, during a separate and private Five-Minute Speech Sample, lower criticism by partners was associated with higher depressive symptoms, especially when those who chose the interaction topic were also clinically depressed. All analyses controlled for relationship adjustment. These results suggest that spouses with higher depressive symptoms and clinical depression diagnoses may be suppressing otherwise ordinary criticism expression toward their nondepressed partners; furthermore, nondepressed partners of depressed people are especially likely to display less criticism toward their spouse in a private task.

PMID- 29473162 TI - Tumor-associated autoantibodies as early detection markers for ovarian cancer? A prospective evaluation. AB - Immuno-proteomic screening has identified several tumor-associated autoantibodies (AAb) that may have diagnostic capacity for invasive epithelial ovarian cancer, with AAbs to P53 proteins and cancer-testis antigens (CTAGs) as prominent examples. However, the early detection potential of these AAbs has been insufficiently explored in prospective studies. We performed ELISA measurements of AAbs to CTAG1A, CTAG2, P53 and NUDT11 proteins, for 194 patients with ovarian cancer and 705 matched controls from the European EPIC cohort, using serum samples collected up to 36 months prior to diagnosis under usual care. CA125 was measured using electrochemo-luminiscence. Diagnostic discrimination statistics were calculated by strata of lead-time between blood collection and diagnosis. With lead times <=6 months, ovarian cancer detection sensitivity at 0.98 specificity (SE98) varied from 0.19 [95% CI 0.08-0.40] for CTAG1A, CTAG2 and NUDT1 to 0.23 [0.10-0.44] for P53 (0.33 [0.11-0.68] for high-grade serous tumors). However, at longer lead-times, the ability of these AAb markers to distinguish future ovarian cancer cases from controls declined rapidly; at lead times >1 year, SE98 estimates were close to zero (all invasive cases, range: 0.01 0.11). Compared to CA125 alone, combined logistic regression scores of AAbs and CA125 did not improve detection sensitivity at equal level of specificity. The added value of these selected AAbs as markers for ovarian cancer beyond CA125 for early detection is therefore limited. PMID- 29473165 TI - Neural oscillations in the infralimbic cortex after electrical stimulation of the amygdala. Relevance to acute stress processing. AB - The stress system coordinates the adaptive reactions of the organism to stressors. Therefore, dysfunctions in this circuit may correlate to anxiety related disorders, including depression. Comprehending the dynamics of this network may lead to a better understanding of the mechanisms that underlie these diseases. The central nucleus of the amygdala (CeA) activates the hypothalamic pituitary-adrenal axis and brainstem nodes by triggering endocrine, autonomic and behavioral stress responses. The medial prefrontal cortex plays a significant role in regulating reactions to stressors, and is specifically important for limiting fear responses. Brain oscillations reflect neural systems activity. Synchronous neuronal assemblies facilitate communication and synaptic plasticity, mechanisms that cooperatively support the temporal representation and long-term consolidation of information. The purpose of this article was to delve into the interactions between these structures in stress contexts by evaluating changes in oscillatory activity. We particularly analyzed the local field potential in the infralimbic region of the medial prefrontal cortex (IL) in urethane-anesthetized rats after the electrical activation of the central nucleus of the amygdala by mimicking firing rates induced by acute stress. Electrical CeA activation induced a delayed, but significant, change in the IL, with prominent slow waves accompanied by an increase in the theta and gamma activities, and spindles. The phase-amplitude coupling of both slow waves and theta oscillations significantly increased with faster oscillations, including theta-gamma coupling and the nesting of spindles, theta and gamma oscillations in the slow wave cycle. These results are further discussed in neural processing terms of the stress response and memory formation. PMID- 29473163 TI - Binocular response modulation in the lateral geniculate nucleus. AB - The dorsal lateral geniculate nucleus of the thalamus (LGN) receives the main outputs of both eyes and relays those signals to the visual cortex. Each retina projects to separate layers of the LGN so that each LGN neuron is innervated by a single eye. In line with this anatomical separation, visual responses of almost all of LGN neurons are driven by one eye only. Nonetheless, many LGN neurons are sensitive to what is shown to the other eye as their visual responses differ when both eyes are stimulated compared to when the driving eye is stimulated in isolation. This, predominantly suppressive, binocular modulation of LGN responses might suggest that the LGN is the first location in the primary visual pathway where the outputs from the two eyes interact. Indeed, the LGN features several anatomical structures that would allow for LGN neurons responding to one eye to modulate neurons that respond to the other eye. However, it is also possible that binocular response modulation in the LGN arises indirectly as the LGN also receives input from binocular visual structures. Here we review the extant literature on the effects of binocular stimulation on LGN spiking responses, highlighting findings from cats and primates, and evaluate the neural circuits that might mediate binocular response modulation in the LGN. PMID- 29473166 TI - Capillary morphogenesis protein 2 is a novel prognostic biomarker and plays oncogenic roles in glioma. AB - Capillary morphogenesis protein 2 (CMG2) was originally identified through its participation in capillary morphogenesis, and subsequently identified as the second receptor for anthrax toxin (ANTXR2). Although tumor-associated functions of CMG2 have also been reported, the clinical significance and functional mechanism of CMG2 in glioma remain to be elucidated. We assessed the clinicopathological relevance of CMG2 in a cohort of 48 glioma patients as well as through public glioma databases, and explored the function of CMG2 using glioblastoma (GBM) models in vitro and in vivo. CMG2 overexpression was associated with increased tumor grade and poor patient survival. CMG2 promoted G2/M-phase transition during the cell cycle of GBM cells in vitro and contributed to tumor growth in vivo. We also observed that CMG2 is implicated in the activation of extracellular signal-regulated kinases (ERKs), epithelial mesenchymal transition (EMT), migration, and invasion in GBM cells. Transcriptomic analysis of GBM cells with or without CMG2 overexpression indicated that a panel of oncogenic signaling pathways was altered with CMG2 upregulation, implying that CMG2 might orchestrate these signaling pathways to regulate the growth of GBM cells. Yes-associated protein 1 (YAP1) activity was enhanced by CMG2 overexpression but suppressed with CMG2 deficiency. Since YAP1 is critically implicated in GBM, the oncogenic roles of CMG2 in GBM cells might thus be mediated, at least partially, by YAP1. Altogether, CMG2 functioned as an oncogene in glioma cells and is a potential prognostic biomarker or therapeutic target for the clinical treatment of glioma.

AB - The preBotzinger Complex (preBotC), a compact medullary region essential for generating normal breathing rhythm and pattern, is the kernel of the breathing central pattern generator (CPG). Excitatory preBotC neurons in rats project to major breathing-related brainstem regions. Here, we provide a brainstem connectivity map in mice for both excitatory and inhibitory preBotC neurons. Using a genetic strategy to label preBotC neurons, we confirmed extensive projections of preBotC excitatory neurons within the brainstem breathing CPG including the contralateral preBotC, Botzinger Complex (BotC), ventral respiratory group, nucleus of the solitary tract, parahypoglossal nucleus, parafacial region (RTN/pFRG or alternatively, pFL /pFV ), parabrachial and Kolliker-Fuse nuclei, as well as major projections to the midbrain periaqueductal gray. Interestingly, preBotC inhibitory projections paralleled the excitatory projections. Moreover, we examined overlapping projections in the pons in detail and found that they targeted the same neurons. We further explored the direct anatomical link between the preBotC and suprapontine brain regions that may govern emotion and other complex behaviors that can affect or be affected by breathing. Forebrain efferent projections were sparse and restricted to specific nuclei within the thalamus and hypothalamus, with processes rarely observed in cortex, basal ganglia, or other limbic regions, e.g., amygdala or hippocampus. We conclude that the preBotC sends direct, presumably inspiratory-modulated, excitatory and inhibitory projections in parallel to distinct targets throughout the brain that generate and modulate breathing pattern and/or coordinate breathing with other behaviors, physiology, cognition, or emotional state. PMID- 29473168 TI - Structural basis for PDZ domain interactions in the post-synaptic density scaffolding protein Shank3. AB - The Shank proteins are crucial scaffolding elements of the post-synaptic density (PSD). One of the best-characterized domains in Shank is the PDZ domain, which binds to C-terminal segments of several other PSD proteins. We carried out a detailed structural analysis of Shank3 PDZ domain-peptide complexes, to understand determinants of binding affinity towards different ligand proteins. Ligand peptides from four different proteins were cocrystallized with the Shank3 PDZ domain, and binding affinities were determined calorimetrically. In addition to conserved class I interactions between the first and third C-terminal peptide residue and Shank3, side chain interactions of other residues in the peptide with the PDZ domain are important factors in defining affinity. Structural conservation suggests that the binding specificities of the PDZ domains from different Shanks are similar. Two conserved buried water molecules in PDZ domains may affect correct local folding of ligand recognition determinants. The solution structure of a tandem Shank3 construct containing the SH3 and PDZ domains showed that the two domains are close to each other, which could be of relevance, when recognizing and binding full target proteins. The SH3 domain did not affect the affinity of the PDZ domain towards short target peptides, and the schizophrenia linked Shank3 mutation R536W in the linker between the domains had no effect on the structure or peptide interactions of the Shank3 SH3-PDZ unit. Our data show the spatial arrangement of two adjacent Shank domains and pinpoint affinity determinants for short PDZ domain ligands with limited sequence homology.

AB - PURPOSE: The aim of this study is to determine the physical health status and healthy lifestyle behaviors of individuals with mental illness. DESIGN AND METHODS: A descriptive research design was used. The sample of the study consisted of 115 individuals with mental illness. The Health Lifestyle Behaviors Scale II was used to assess the healthy lifestyle behaviors of the participants. FINDINGS: Of the individuals, 49.6% were found to have metabolic syndrome. Individuals with mental illness obtained the lowest score from the physical activity dimension of the scale. PRACTICE IMPLICATIONS: Individuals with mental illness need to receive education and support, especially in terms of nutrition and exercise. PMID- 29473171 TI - Nimodipine confers clinical improvement in two models of experimental autoimmune encephalomyelitis. AB - Multiple sclerosis is characterised by inflammatory neurodegeneration, with axonal injury and neuronal cell death occurring in parallel to demyelination. Regarding the molecular mechanisms responsible for demyelination and axonopathy, energy failure, aberrant expression of ion channels and excitotoxicity have been suggested to lead to Ca2+ overload and subsequent activation of calcium-dependent damage pathways. Thus, the inhibition of Ca2+ influx by pharmacological modulation of Ca2+ channels may represent a novel neuroprotective strategy in the treatment of secondary axonopathy. We therefore investigated the effects of the L type voltage-gated calcium channel blocker nimodipine in two different models of mouse experimental autoimmune encephalomyelitis (EAE), an established experimental paradigm for multiple sclerosis. We show that preventive application of nimodipine (10 mg/kg per day) starting on the day of induction had ameliorating effects on EAE in SJL/J mice immunised with encephalitic myelin peptide PLP139-151 , specifically in late-stage disease. Furthermore, supporting these data, administration of nimodipine to MOG35-55 -immunised C57BL/6 mice starting at the peak of pre-established disease, also led to a significant decrease in disease score, indicating a protective effect on secondary CNS damage. Histological analysis confirmed that nimodipine attenuated demyelination, axonal loss and pathological axonal beta-amyloid precursor protein accumulation in the cerebellum and spinal cord in the chronic phase of disease. Of note, we observed no effects of nimodipine on the peripheral immune response in EAE mice with regard to distribution, antigen-specific proliferation or activation patterns of lymphocytes. Taken together, our data suggest a CNS-specific effect of L-type voltage-gated calcium channel blockade to inflammation-induced neurodegeneration. PMID- 29473172 TI - Ceftriaxone-induced drug reaction mimicking acute splenic sequestration crisis in a child with hemoglobin SC disease. AB - BACKGROUND: Acute splenic sequestration crisis is a complication of sickle cell disease (SCD) occurring when intrasplenic red blood cell (RBC) sickling prevents blood from leaving the spleen, causing acute splenic enlargement. Although typically seen in young children, it has been reported in older children with hemoglobin (Hb)SC disease, eventually resulting in functional asplenia. Ceftriaxone is a frequently used antibiotic of choice for children with SCD, because of its efficacy against invasive pneumococcal disease. CASE REPORT: We report a case of a 9-year-old female with HbSC disease, who had a fatal reaction after receiving a dose of ceftriaxone in the outpatient clinic for fever. Her Hb level decreased abruptly from 9.3 to 2.3 mg/dL. RBC clumps with no visible hemolysis were observed in the postreaction sample. Autopsy examination revealed marked splenomegaly with acute congestion and sickled cells in the spleen and liver. Serologic testing revealed a positive direct antiglobulin test with polyspecific antibody, anti-C3, and anti-C3d, but negative with anti immunoglobulin G. Ceftriaxone-dependent RBC antibodies were detected in her serum and RBC eluate when tested in the presence of the drug. CONCLUSION: We report a new presentation of ceftriaxone-induced drug reaction in a patient with SCD mimicking an acute splenic sequestration crisis. Review of the literature for cases of ceftriaxone-induced drug reactions in pediatric patients revealed nine previously reported cases of ceftriaxone-induced immune hemolytic anemia in children with SCD since 1995, but none with an initial presentation suggestive of acute splenic sequestration crisis. PMID- 29473169 TI - Animal models of Wilson disease. AB - Wilson disease (WD) is an autosomal recessive disorder of copper metabolism manifesting with hepatic, neurological and psychiatric symptoms. The limitations of the currently available therapy for WD (particularly in the management of neuropsychiatric disease), together with our limited understanding of key aspects of this illness (e.g. neurological vs. hepatic presentation) justify the ongoing need to study WD in suitable animal models. Four animal models of WD have been established: the Long-Evans Cinnamon rat, the toxic-milk mouse, the Atp7b knockout mouse and the Labrador retriever. The existing models of WD all show good similarity to human hepatic WD and have been helpful in developing an improved understanding of the human disease. As mammals, the mouse, rat and canine models also benefit from high homology to the human genome. However, important differences exist between these mammalian models and human disease, particularly the absence of a convincing neurological phenotype. This review will first provide an overview of our current knowledge of the orthologous genes encoding ATP7B and the closely related ATP7A protein in C. elegans, Drosophila and zebrafish (Danio rerio) and then summarise key characteristics of rodent and larger mammalian models of ATP7B-deficiency. PMID- 29473173 TI - Ultraviolet light-based pathogen inactivation and alloimmunization after platelet transfusion: results from a randomized trial. AB - BACKGROUND: The current study explored whether pathogen-reduction treatment of platelet components before transfusion would decrease the risk of alloimmunization. STUDY DESIGN AND METHODS: Study participants were patients with hematologic cancer who were included in two parallel, randomized clinical trials testing pathogen-reduction treatment versus conventional platelets using the Mirasol or Intercept pathogen-reduction systems. Patients who had a baseline, pretransfusion sample and a follow-up, posttransfusion sample were included in the study (n = 179 patients in each study arm). Human leukocyte antigen antibody levels were determined using a commercial multianalyte, bead-based assay. RESULTS: The rate of human leukocyte antigen Class I alloimmunization at the clinical sites in recipients of conventional platelets was low at the highest assay cutoff (range, 1.2%-5.9%). Consistent with prior studies, human leukocyte antigen antibodies were first detected from 3 to 35 days after transfusion. There were no statistically significant differences between alloimmunization rates in patients who received pathogen-reduction treatment versus conventional platelet transfusions. Although he difference was not statistically significant, the effect size for protection from alloimmunization was greatest for high-level human leukocyte antigen Class I antibodies (approximately threefold) in the Intercept-treated patients compared with those who received conventional platelets. In the Mirasol study, only two patients and one patient in the control group developed medium-level or high-level antibodies, respectively, so it was impossible to determine an effect size for potential protection. CONCLUSIONS: The current study was not sufficiently powered to determine whether pathogen reduction treatment provides protection from human leukocyte antigen alloimmunization in platelet transfusion recipients. The data presented will be useful in the design of future trials and endpoints powered to detect a protective effect. PMID- 29473174 TI - Variation in red cell transfusion decisions in the intensive care unit - a nationwide survey in the Netherlands. AB - BACKGROUND AND OBJECTIVES: Most guidelines recommend a restrictive transfusion trigger of 7 g/dl. It is unclear whether this resulted in more uniform transfusion practices. The primary objective was to uncover the extent of variation in transfusion decisions within four scenarios of critically ill patients among critical care physicians in the Netherlands. MATERIALS AND METHODS: An online survey comprising four different hypothetical clinical scenarios was sent to all members of the Dutch Society of Intensive Care. The scenarios represented patients with acute myocardial infarction (Hb 8.5 g/dl), abdominal sepsis (Hb 7.1 g/dl), traumatic brain injury (TBI) (Hb 7.9 g/dl) and post-surgical complications (Hb 7.3 g/dl). The questions explored the decision whether or not to transfuse and a ranking of clinical characteristics playing the most important role in the transfusion decision. RESULTS: A total of 224 members (22%) participated in the study of whom 188 (84%) completed all questions. The percentages of respondents that decided to transfuse ranged from 25.9% in the scenario with TBI to 81.6% in the scenario with post-surgical complications. Most controversy was seen in the scenario with sepsis for which 43.2% decided to transfuse, whereas 56.8% decided not to. Haemoglobin level, diagnosis and haemodynamics were most important for the transfusion decision in all scenarios. CONCLUSIONS: Physicians decided differently on red-blood-cell transfusion given the clinical scenarios and weighed clinical characteristics differently in their transfusion decisions. These findings suggest there still is substantial variation in critical care transfusion practice.

AB - Deciphering the complex milieu that makes up the tumor microenvironment (TME) and the signaling engaged by TME cytokines continues to provide novel targets for therapeutic intervention. The IL-6 family member oncostatin M (OSM) has recently emerged as a potent driver of tumorigenesis, metastasis, and therapy failure, molecular programs most frequently attributed to IL-6 itself. In a recent issue of The Journal of Pathology, Kucia-Tran et al describe how elevated oncostatin M receptor (OSMR) expression results in a feed-forward loop involving the de novo production of both OSM and OSMR to facilitate aggressive properties in squamous cell carcinoma (SCC). Here, we discuss how new findings implicating OSM in conferring aggressive cancer cell properties can be leveraged to suppress metastatic outgrowth and therapy failure in SCC as well as other cancers.

AB - Bm and A1 Bm phenotypes are the most frequent ABO variants in the Japanese population. The B antigen on Bm red blood cells is only detectable by adsorption and elution tests, and plasma B-transferase activity is usually detected at half or less levels compared with that of common B. Recently, a B allele lacking an erythroid cell-specific transcription enhancer in intron 1 of the ABO gene was identified from individuals with Bm and A1 Bm phenotypes, which could explain the unique serologic properties of Bm . In the Japanese Red Cross Society, eight Blood Centers tested blood samples from donors throughout Japan and collected blood samples from 888 Bm and 415 A1 Bm individuals. DNA analysis revealed that 1300 of 1303 (99.77%) individuals had the B allele with a 5.8 kb deletion (c.28 + 5110_10889del), which included the enhancer element.

AB - BACKGROUND: Endothelial colony-forming progenitor cells (ECFCs) are promising candidates for cell therapies. However, ECFC translation to the clinic requires optimized isolation and manufacture technologies according to good manufacturing practice (GMP). STUDY DESIGN AND METHODS: ECFCs were manufactured from steady state peripheral blood (PB) leukapheresis (11 donors), using GMP-compliant technologies including pooled human platelet (PLT) lysate, and compared to human umbilical cord endothelial cells, human aortic endothelial cells, and human cerebral microvascular endothelial cells. Specific variables assessed were growth kinetics, phenotype, trophic factors production, stimulation of tube formation, and Dil-AcLDL uptake. RESULTS: ECFCs could be isolated from PB leukapheresis units with mean processed volume of 5411 mL and mean white blood cell (WBC) concentration factor of 8.74. The mean frequency was 1.44 * 10-8 ECFCs per WBC, corresponding to a mean of 177.8 ECFCs per apheresis unit. Expandable for up to 12 cumulative population doublings, calculated projection showed that approximately 730 * 103 ECFCs could be manufactured from 1 apheresis unit. ECFCs produced epidermal growth factor, hepatocyte growth factor, vascular endothelial growth factor (VEGF)-A, PLT-derived growth factor-B, interleukin-8, and monocyte chemoattractant protein-1, featured high potential for capillary-like tubes formation, and showed no telomerase activity. They were characterized by CD29, CD31, CD44, CD105, CD117, CD133, CD144, CD146, and VEGF-R2 expression, with the most common subpopulation CD34+CD117-CD133-. Compared to controls, ECFCs featured greater Dil-AcLDL uptake and higher expression of CD29, CD31, CD34, CD44, CD144, and VEGF-R2. CONCLUSIONS: Here we show that isolation of ECFCs with proangiogenic profile from steady-state PB leukapheresis is feasible, marking a first step toward ECFC product manufacture according to GMP. PMID- 29473178 TI - PAS-C platelets contain less plasma protein, lower anti-A and anti-B titers, and decreased HLA antibody specificities compared to plasma platelets. AB - BACKGROUND: Platelets (PLTs) collected and stored in PLT additive solution Intersol (PAS-C) are presumed to reduce recipient exposure to donor plasma components; however, the effects of PAS-C on PLT supernatant composition are poorly defined. Therefore, we compared the total protein concentration, isohemagglutinin titers, and HLA antibodies in supernatants of PAS-C PLTs to plasma PLTs. STUDY DESIGN AND METHODS: Apheresis PLTs from group O blood donors were collected into either 100% donor plasma (n = 50) or a mixture of 65% PAS C/35% donor plasma (n = 50). Within 12 hours of collection, samples of the PLT supernatant were frozen and stored. PLT supernatants were assayed for total protein concentration and anti-A and anti-B titers and screened for HLA antibodies. Samples positive for HLA antibodies were further tested using single antigen bead assays to determine antibody strength and specificity. RESULTS: Supernatants of PAS-C PLTs had significantly lower total protein concentration and anti-A and anti-B titers compared to plasma PLTs. There was no significant difference in the number of HLA antibody screen-positive PAS-C (3/50) compared to plasma PLT supernatants (2/50); however, the HLA antibody screen-positive supernatants of PAS-C PLTs had fewer HLA specificities (2) compared to those of the plasma PLTs (18). CONCLUSION: Decreased plasma proteins likely underlie lower rates of allergic and febrile, nonhemolytic transfusion reactions from the infusion of PAS-C PLTs. Decreased anti-A and anti-B titers may prevent hemolysis from minor ABO mismatch. Lower HLA antibody specificities may mitigate transfusion-related acute lung injury. PMID- 29473179 TI - Does docetaxel prolong survival of patients with non-metastatic castration resistant prostate cancer? AB - BACKGROUND: Guidelines define docetaxel as a first-line therapeutic option for metastatic castration-resistant prostate cancer (mCRPC). However, the role of docetaxel in non-metastatic castration-resistant prostate cancer (nmCRPC) has not been fully investigated. The aim of this retrospective study was to evaluate the potential role of docetaxel in nmCRPC. Clinical outcomes including overall survival were compared between CRPC patients who had docetaxel introduced while in nonmetastatic versus metastatic diseases. METHODS: A total of 98 CRPC patients had docetaxel therapy. Of these 46 patients received docetaxel for nmCRPC, and 52 had distant metastases. Clinical outcomes from the time of diagnosis of CRPC were compared retrospectively between groups. RESULTS: The median observation period after the diagnosis of CRPC in these patients was 42 months (range, 3-166). Overall survival (OS) was significantly longer in the nmCRPC group than in the mCRPC group (not reached vs 52.2 months, respectively, P = 0.006). Multivariate analysis showed that longer time to CRPC, docetaxel use in nmCRPC, and use of abiraterone acetate and/or enzalutamide were significant predictors for improved OS (P = 0.04, 0.019 and 0.002, respectively). The incidence and profile of adverse events did not differ significantly between groups. CONCLUSIONS: Earlier induction of docetaxel in nmCRPC patients may prolong OS. Further prospective studies in more patients will be required to confirm our findings. PMID- 29473180 TI - Faces presenting sadness enhance self-control abilities in gifted adolescents. AB - Self-regulation skills refer to processes allowing emotional and cognitive adaptation of the individual. Some gifted adolescents are known for their imbalance between high intellectual abilities and low emotional skills. Thus, this study aimed at examining the interplay between emotion and cognition in gifted and non-gifted adolescents. A stop-signal task, a response inhibition task including neutral, happy, or sad faces as signal triggering inhibition, was administered to 19 gifted and 20 typically developing male adolescents (12-18 years old). Gifted adolescents showed lower response inhibition abilities than non-gifted adolescents in the neutral and happy face conditions. Sad faces in gifted adolescents were associated with higher response inhibition compared to happy condition. In typically developing adolescents, emotional information (happy or sad faces) was related to lower response inhibition compared to neutral face condition. This study highlights that gifted adolescents present different self-regulation skills than their typically developing peers. Statement of contribution What is already known on this subject? Some gifted adolescents present higher intellectual abilities alongside with lower socio-emotional skills. Self-regulation skills refer to processes allowing emotional and cognitive adaptation. Self-regulation skills might help to understand gifted adolescents, but remain scarcely studied. What does this study adds? Task relevant emotional information impaired cognitive control in typically developing adolescents. Gifted adolescents are able to use sad faces to enhance their cognitive control abilities. PMID- 29473181 TI - Bridging to a Long-Term Ventricular Assist Device With Short-Term Mechanical Circulatory Support. AB - Implanting short-term mechanical circulatory support (MCS) devices as a bridge-to decision is increasingly popular. However, outcomes have not been well studied in patients who receive short-term MCS before receiving long-term left ventricular assist device (LVAD) support. We analyzed outcomes in our single-center experience with long-term continuous-flow (CF)-LVAD recipients with pre implantation short-term MCS. From November 2003 through March 2016, 526 patients (mean age, 54.7 +/- 13.5 years) with chronic heart failure (mean ejection fraction, 21.7 +/- 3.6%) underwent implantation of either the HeartMate II (n = 403) or the HeartWare device (n = 123). Before implantation, 269 patients received short-term MCS with the TandemHeart, the Impella 2.5/5.0, an intra aortic balloon pump (IABP), venoarterial extracorporeal membrane oxygenation (VA ECMO), or the CentriMag. The short-term MCS patients were compared with the CF LVAD-only patients regarding preoperative demographics, incidence of postoperative complications, and long-term survival. The 269 patients received the following short-term MCS devices: 57 TandemHeart, 27 Impella, 172 IABP, 12 VA ECMO, and 1 CentriMag. Survival at 30 days, 6 months, 1 year, and 2 years was 94.2, 87.2, 79.4, and 72.4%, respectively, for CF-LVAD-only patients versus 91.0, 78.1, 73.4, and 65.6%, respectively, for short-term MCS + CF-LVAD patients (P = 0.17). Within the short-term MCS group, survival at 24 months was poorest for patients supported with VA-ECMO or the TandemHeart (P = 0.03 for both), and survival across all four time points was poorest for patients supported with VA ECMO (P = 0.02). Short-term MCS was not an independent predictor of mortality in multivariate Cox regression models (hazard ratio = 1.12, 95% confidence interval = 0.84-1.49, P = 0.43). In conclusion, we found that using short-term MCS therapy except for VA-ECMO-as a bridge to long-term CF-LVAD support was not associated with poorer survival. PMID- 29473182 TI - The androgen receptor malignancy shift in prostate cancer. AB - BACKGROUND: Androgens and the androgen receptor (AR) are necessary for the development, function, and homeostatic growth regulation of the prostate gland. However, once prostate cells are transformed, the AR is necessary for the proliferation and survival of the malignant cells. This change in AR function appears to occur in nearly every prostate cancer. We have termed this the AR malignancy shift. METHODS: In this review, we summarize the current knowledge of the AR malignancy shift, including the DNA-binding patterns that define the shift, the transcriptome changes associated with the shift, the putative drivers of the shift, and its clinical implications. RESULTS: In benign prostate epithelial cells, the AR primarily binds consensus AR binding sites. In carcinoma cells, the AR cistrome is dramatically altered, as the AR associates with FOXA1 and HOXB13 motifs, among others. This shift leads to the transcription of genes associated with a malignant phenotype. In model systems, some mutations commonly found in localized prostate cancer can alter the AR cistrome, consistent with the AR malignancy shift. Current evidence suggests that the AR malignancy shift is necessary but not sufficient for transformation of prostate epithelial cells. CONCLUSIONS: Reinterpretation of prostate cancer genomic classification systems in light of the AR malignancy shift may improve our ability to predict clinical outcomes and treat patients appropriately. Identifying and targeting the molecular factors that contribute to the AR malignancy shift is not trivial but by doing so, we may be able to develop new strategies for the treatment or prevention of prostate cancer. PMID- 29473183 TI - Peritoneal Dialysis Fluid-Induced Fragmentation of Golgi Apparatus as a Biocompatibility Marker. AB - In vitro biocompatibility assessments that consider physiologically appropriate conditions of cell exposure to peritoneal dialysis fluids (PDFs) are still awaited. In this study, we found that fragmentation of Golgi apparatus occurred in a pH-dependent manner within 30-min exposure to five distinct commercially available PDFs, which showed no marked difference in their effects on cell viability in the conventional MTT assay. Fluorescence microscopy analysis of labeling antibody against cis-Golgi protein GM130 indicated that the stacked cisternal structure was maintained in the perinuclear area of both M199 culture medium and a neutral-pH PDF groups. However, this specific structure became partially disassembled over time even in a neutral-pH PDF, and fragmentation was markedly enhanced in cells exposed to neutralized-pH PDFs in correspondence with their intracellular pH; moreover, in acidic PDFs, Golgi staining was diffuse and scattered in the entire cytoplasm and showed partial aggregation. The Golgi fragmentation markedly observed with the neutralized PDFs could be reversed by replacing either the media with a neutral-pH medium or a mixture of PDF and PD effluent (PDF) in a gradient manner mimicking clinical conditions. Furthermore, although weaker than pH effect, notable effects of other PDF-related factors were also observed after 30-min exposure to pH-adjusted PDFs. Lastly, the results of studies conducted using MAPK/SAPK inhibitors indicated that the mechanism underlying the Golgi fragmentation described here differs from that associated with the fragmentation that occurs at the G2/M checkpoint in the cell cycle. We conclude that Golgi fragmentation is suitable for rapid biocompatibility assessment of PDF not only because of its strong pH dependence but also because the fragmentation is recognizably affected by PDF constituents. PMID- 29473184 TI - Quantitative determination of risperidone, paliperidone and olanzapine in human serum by liquid chromatography-tandem mass spectrometry coupled with on-line solid-phase extraction. AB - A recent guideline recommends therapeutic drug monitoring for risperidone, paliperidone and olanzapine, which are frequently used second-generation antipsychotics. We developed a simple high-performance liquid chromatography tandem mass spectrometry coupled with an online solid-phase extraction method that can be used to measure risperidone, paliperidone and olanzapine using small (40 MUL) samples. The analytes were extracted from serum samples automatically pre-concentrated and purified by C8 (5 MUm, 2.1 * 30 mm) solid-phase extraction cartridges, then chromatographed on an XbidgeTM C18 column (3.5 MUm, 100 * 2.1 mm) thermostatted at 30 degrees C with a mobile phase consisting of 70% acetonitrile and 30% ammonium hydroxide 1% solution at an isocratic flow rate of 0.3 mL/min, and detected with tandem mass spectrometry. The assay was validated in the concentration range from 2.5 to 160 ng/mL. Intra- and inter-day precision for all analytes was between 1.1 and 8.2%; method accuracy was between 6.6 and 7.6%. The risperidone and paliperidone assay was compared with a high-performance liquid chromatography-ultraviolet assay currently used in our hospital for risperidone and paliperidone therapeutic drug monitoring, and the results of weighted Deming regression analysis showed good agreement. For the olanzapine assay, we compared 20 samples in separate re-assays on different days; all the relative errors were within the 20% recommended limit. PMID- 29473185 TI - Spectrum-effect relationship between HPLC fingerprints and hypolipidemic effect of Curcuma aromatica. AB - Curcuma aromatica is used as a traditional Chinese medicine, and it is mainly distributed in Guangxi, China. In this study, 10 batches of C. aromatica were collected from different origins in Guangxi. The fingerprints were established by HPLC technique to investigate the quality stability of C. aromatica. The spectrum effect relationship between HPLC fingerprints and hypolipidemic effect of C. aromatica was assessed by similarity analysis, gray relational analysis and multiple linear regression analysis. From the results, the similarity values between each batch of C. aromatica and reference fingerprint were >0.880, indicating the good quality stability of the 10 batches of C. aromatica. Twenty common peaks were selected as the fingerprints to evaluate the quality and hypolipidemic effect of C. aromatica. The results of spectrum-effect relationship showed that peaks 10, 18, 13, 15 and 17 in the fingerprints were closely related to hypolipidemic effect. This study successfully established the spectrum-effect relationship between HPLC fingerprints and hypolipidemic effect of C. aromatica, which provided methods for quality control and more effectively studies on bioactive compounds of C. aromatica. It could also provide a new simple and effective method for utilizing the fingerprints to optimize the Chinese prescription and develop traditional Chinese medicine. PMID- 29473186 TI - Being in safe hands: Patients' perceptions of how cancer services may support psychological well-being. AB - AIMS: To explore how cancer services may positively promote and support patients' well-being throughout treatment. Specifically to identify components of care that are important to patients and meet their needs. BACKGROUND: Patients commonly experience stress and uncertainty during their cancer journey which can have a negative impact on their psychological health and quality of life. Comparatively, little is known about how patients may experience positive well-being during their treatment experience. DESIGN: Qualitative study using semi-structured interviews. METHODS: Interviews were conducted between 2014 - 2015 with a purposive sample of 30 individuals who were at the beginning, middle or end of treatment for lung, colorectal and head and neck cancer. The majority were outpatients and receiving radiotherapy, chemotherapy or a combination of these. The recordings were analysed using thematic analysis. RESULTS: Patients may obtain a range of positive health benefits derived from contact with staff, patients and public. Positive emotional gains were based on "being in safe hands" and part of the collective effort to eradicate cancer. This appeared to assist patients achieve favourable treatment responses, however, a range of factors encouraged and hindered them to express concerns. CONCLUSION: Interactions with staff, patients and the hospital environment supported well-being in those receiving cancer treatment. Findings demonstrate additional areas for research including the development of interventions to facilitate peer support and the implementation of communication strategies that promote well-being.

AB - Three main properties are responsible for the microbial attractiveness of denture surfaces: roughness, hydrophilicity and free surface energy. This study investigated whether CAD/CAM-fabricated dentures are more favourable for these surface properties than conventionally fabricated dentures. The mucosal surface roughness of 54 standardised study dentures was measured using contact profilometry. The surface hydrophilicity and free surface energy of 70 standardised denture resin specimens were determined by contact angle measurements. Both experimental settings compared AvaDent (AD), Baltic Denture System (BDS), Vita VIONIC (VV), Whole You Nexteeth (WN) and Wieland Digital Dentures (WDD) surfaces with conventionally manufactured denture surfaces (control group). These data were analysed using ANOVA together with Tukey's test or the Games-Howell post hoc test. All CAD/CAM dentures had lower mean surface roughness values than conventional dentures. For AD, VV, WN and WDD, the differences were statistically significant. Vita VIONIC (P < .001), coated WN (P < .001), AD (P = .023) and BDS specimens (P = .027) were significantly more hydrophilic than the control group. All measured surface energies were of similar magnitude (mean values between 31.82 and 33.68 mJ/m2 ), and only coated WN specimens had a significantly increased mean value (66.62 mJ/m2 , P < .001). Although most CAD/CAM dentures have smoother and more hydrophilic surfaces than conventional dentures, there is no difference in their free surface energy, except for coated dentures. PMID- 29473189 TI - An umbrella review of clinical practice guidelines for the management of patients with hip fractures and a synthesis of recommendations for the pre-operative period. AB - AIM: The aim of this review was to locate, retrieve and critically appraise practice guidelines for the management of hip fractures. Given increasing evidence that the early recognition and management of these fractures is integral to achieving optimal outcomes, recommendations for the pre-operative period were synthesized and compared. BACKGROUND: Hip fractures are associated with high rates of adverse outcomes and high healthcare costs which has resulted in the development of multiple practice guidelines to inform clinical decision-making. DESIGN: An umbrella review of practice guidelines was conducted which included a critical appraisal using the Appraisal of Guidelines, Research and Evaluation-II instrument and a synthesis of pre-operative management recommendations. DATA SOURCES: Multi-phased search for practice guidelines published in English using three bibliographic databases; three guideline network websites and three healthcare safety and quality organization websites with no date limit applied. Search was supplemented by contacting front-line knowledge users and content experts. REVIEW METHODS: Steps for evidence-informed practice were followed: form question then search for, appraise and synthesize the evidence. RESULTS: Five practice guidelines were appraised revealing significant variability in quality. The largest variability was in "rigour of development". Recommendations for pre operative management were grouped into six categories: timing of surgery, expedited patient management, identification and treatment of correctable co morbidities, pain management, preventative measures and multidisciplinary management. CONCLUSION: Results of this review illustrate that not all practice guidelines are of equal quality. Given the costs associated with the development and maintenance of high-quality practice guidelines, such work may be more efficiently completed through international collaborations and then adapted for national and regional healthcare contexts. PMID- 29473190 TI - Seven novel COL7A1 mutations identified in patients with recessive dystrophic epidermolysis bullosa from Mexico. AB - Recessive dystrophic epidermolysis bullosa (RDEB; OMIM #226600) is one of the most devastating subtypes of epidermolysis bullosa, a group of skin and mucous membrane blistering disorders often associated with extracutaneous manifestations. RDEB is caused by mutations in COL7A1, the gene encoding type VII collagen (C7), and to date over 700 different mutations in the 8835 nucleotides constituting the open reading frame or adjacent exon-intron boundaries of COL7A1 have been described. We used targeted next-generation sequencing to identify seven previously unreported mutations in a cohort of 17 Mexican patients who were diagnosed with RDEB based on clinical presentation and immunoepitope mapping. Our study expands the spectrum of mutations identified in this cohort, including those suitable for emerging therapies reliant on precise genotyping. PMID- 29473192 TI - Thinness and muscularity internalization: Associations with disordered eating and muscle dysmorphia in men. AB - OBJECTIVE: The tripartite influence model of body image identifies internalization of societal body ideals as a risk factor for developing body dissatisfaction, and subsequent disordered eating behavior. In men, internalization of two dimensions of body image ideals, thinness and muscularity, is associated with body dissatisfaction and eating concerns. However, it is unknown how thinness and muscularity internalization interact in predicting muscle dysmorphia and disordered eating in men. METHOD: Data were collected online from 180 undergraduate men, with ages ranging from 18 to 33 years (19.6, SD = 2.6). Regression models were used to test the interactive effects of thinness and muscularity internalization on (a) muscle dysmorphia symptoms and (b) disordered eating. Subsequent simple slope analyses probed effects at the mean, and +/-1 standard deviation of thinness internalization. RESULTS: Muscularity and thinness internalization were independently positively related to muscle dysmorphia symptoms and disordered eating. Additionally, a significant interaction revealed that muscularity internalization was increasingly related to muscle dysmorphia symptoms as thinness internalization decreased. DISCUSSION: Men who internalized the muscular ideal had higher levels of muscle dysmorphia when they did not highly internalize the thin ideal. However, greater internalization of both the muscularity and thin ideal independently may be most relevant in the development of disordered eating in men. Future research is needed to explore variability in experiences of muscle dysmorphia compared with disordered eating in males. PMID- 29473191 TI - Body composition and physical fitness in women with bulimia nervosa or binge eating disorder. AB - OBJECTIVE: Knowledge about physical fitness in women with bulimia nervosa (BN) or binge-eating disorder (BED) is sparse. Previous studies have measured physical activity largely through self-report, and physical fitness variables are mainly restricted to body mass index (BMI) and bone mineral density. We expanded the current knowledge in these groups by including a wider range of physical fitness indicators and objective measures of physical activity, assessed the influence of a history of anorexia nervosa (AN), and evaluated predictive variables for physical fitness. METHOD: Physical activity, blood pressure, cardiorespiratory fitness (CRF), muscle strength, body composition, and bone mineral density were measured in 156 women with BN or BED, with mean (SD) age 28.4 years (5.7) and BMI 25.3 (4.8) kg m-2 . RESULTS: Level of physical activity was higher than normative levels, still <50% met the official physical activity recommendation. Fitness in women with BN were on an average comparable with recommendations or normative levels, while women with BED had lower CRF and higher BMI, VAT, and body fat percentage. We found 10-12% with masked obesity. A history of AN did not predict current physical fitness, still values for current body composition were lower when comparing those with history of AN to those with no such history. DISCUSSION: Overall, participants with BN or BED displayed adequate physical fitness; however, a high number had unfavorable CRF and body composition. This finding calls for inclusion of physical fitness in routine clinical examinations and guided physical activity and dietary recommendations in the treatment of BN and BED.

PMID- 29473194 TI - Radiographic measurements of the hindlimbs in crab-eating foxes (Cerdocyon thous, Linnaeus, 1766). AB - Life expectancy of crab-eating foxes in captivity is approximately 11 years, which favours the development of diseases including orthopaedic disorders. However, to understand disorders that may affect these animals, it is worth determining a normal range of measurements. Therefore, this study aimed to evaluate radiographic measurements of joint angles of the hindlimbs and the ratio of patellar ligament length to patellar length in healthy crab-eating foxes. Fifteen captive crab-eating foxes (Cerdocyon thous), eight males and seven females, aged more than 1 year old, weighing 5.5-7.9 kg were used. Anatomic and mechanical femoral joint angles were assessed in ventrodorsal radiographic views, and mediolateral views were taken to measure patellar ligament length and patellar length, and the tibial plateau angle. The right and left hindlimbs were evaluated. All measurements were conducted in triplicate by the same investigator. No statistically significant differences were observed between sides in the radiographic measurements. The anatomic lateral proximal femoral angle and the anatomic lateral distal femoral angle recorded mean values of 95.43 degrees and 92.75 degrees , respectively. The mechanical lateral proximal femoral angle and the mechanical lateral distal femoral angle recorded mean values of 93.39 degrees and 96.75 degrees , respectively. Inclination angles measured according to the Tomlinson, Hauptman A and Hauptman B methods were 133.80 degrees , 147.32 degrees and 128.63 degrees , respectively. The tibial plateau recorded 18.77 degrees , and the ratio of the patellar ligament length to the patellar length was 1.99. In conclusion, the collected data are important to characterize the normal values of crab-eating fox limbs. PMID- 29473195 TI - Determination of metoserpate, buquinolate, and diclofenac in pork, eggs, and milk using liquid chromatography-tandem mass spectrometry. AB - In this work, a method was developed for the simultaneous determination of residual metoserpate, buquinolate and diclofenac in pork, milk, and eggs. Samples were extracted with 0.1% formic acid in acetonitrile, defatted with n-hexane, and filtered prior to analysis using liquid chromatography-tandem mass spectrometry. The analytes were separated on a C18 column using 0.1% acetic acid and methanol as the mobile phase. The matrix-matched calibration curves showed good linearity over a concentration range of 5-50 ng/g with coefficients of determination (R2 ) >=0.991. The intra- and inter-day accuracies (expressed as recovery percentage values) calculated using three spiking levels (5, 10, and 20 MUg/kg) were 80 108.65 and 74.06-107.15%, respectively, and the precisions (expressed as relative standard deviation) were 2.86-13.67 and 0.05-11.74%, respectively, for the tested drugs determined in various matrices. The limits of quantification (1 and 2 MUg/kg) were below the uniform residual level (0.01 mg/kg) set for compounds that have no specific maximum residue limit (MRL). The developed method was tested using market samples and none of the target analytes was detected in any of the samples. The validated method proved to be practicable for detection of the tested analytes in pork, milk, and eggs. PMID- 29473196 TI - CD30-positive primary cutaneous anaplastic large cell lymphoma with coexistent pseudocarcinomatous hyperplasia. AB - CD30-positive primary cutaneous anaplastic large cell lymphoma (C-ALCL) is an indolent type of cutaneous lymphoma with favourable clinical prognosis. Pseudocarcinomatous hyperplasia (PCH) is a rare benign epithelial condition that can resemble invasive squamous cell carcinoma both clinically and histopathologically. PCH predominantly occurs in CD30-positive lymphoproliferative disorders. We report a 75-year-old woman with PCH in a multifocal C-ALCL located on the scalp and right retroauricular area, which rapidly responded to treatment with psoralen ultraviolet A photochemotherapy. Comprehensive virological analyses for potential oncogenic viruses, including Epstein-Barr virus, human herpesvirus-8, human papillomaviruses, the recently discovered cutavirus and nine different human polyomaviruses, were negative. PMID- 29473197 TI - Heritability of the airway structure and head posture using twin study. AB - Inherited traits of obstructive sleep apnoea (OSA) may have link to the heritability of the airway anatomy. The aim of this study was to investigate heritability of the airway anatomy by comparing skeletal and soft tissue features of Korean monozygotic twins (MZ) and dizygotic twins (DZ). In total, 72 participants (mean age, 41.5 +/- 5.9 years; 40 males, 32 females) including 48 MZ (24 pairs) and 24 DZ (12 pairs) with same sex were participated. The craniofacial, craniovertebral, hyoideal and pharyngeal parameters were measured using lateral cephalograms. The genetic analysis was performed using Falconer's method. High heritability was detected in the hyoid position and inclination of the cervical column. The velopharyngeal and hypopharyngeal dimensions showed higher heritability compared to those of the nasopharynx and oropharynx. The body mass index (BMI) had interactions with the nasopharyngeal and hypopharyngeal dimensions and length of the tongue and soft palate. The mandibular growth had correlations with the nasopharyngeal and hypopharyngeal dimensions. The vertical skeletal relationships appeared to have interaction with the nasopharyngeal, velopharyngeal and hypopharyngeal dimensions, as well as length of the tongue and soft palate. A forwarded inclination of the cervical columns was seen in connections with BMI and the nasopharyngeal and hypopharyngeal dimensions. The airway structures and head postures seemed to be under strong genetic controls. The airway dimensions had associations with BMI, head postures and skeletal structures which showed high heritability. Forwarded head postures would be physiological adaptations of compromised airway adequacy by increased BMI and retrognathia. PMID- 29473198 TI - Relationship between nurse psychological empowerment and job satisfaction: A systematic review and meta-analysis. AB - AIMS: This systematic review and meta-analysis aimed to synthesize and analyse studies that explored the relationship between the psychological empowerment and job satisfaction of nurses. BACKGROUND: Nurse turnover is an important cause of staff shortage. Job satisfaction is a major predictor of nurse turnover and is connected to the psychological empowerment of nurses. DESIGN: This systematic review and meta-analysis is based on the Joanna Briggs Institute guidelines. DATA SOURCES: A total of 1,572 articles on psychological empowerment and job satisfaction were retrieved from PubMed, PsycINFO, EMBASE and Web of Science. The articles were written in English and published before or by April 2017. METHODS: Studies on the relationship between psychological empowerment and job satisfaction were summarized. RESULTS: The majority of the included studies revealed that psychological empowerment and job satisfaction are significantly correlated. Only two studies showed that the two factors are not significantly correlated. The result of this meta-analysis is consistent with the results of most studies. One study reported that psychological empowerment partially mediates the structural empowerment and job satisfaction of school health nurses. Two studies, however, did not find that the mediating role of psychological empowerment between structural empowerment and job satisfaction. CONCLUSION: The results of this review provided evidence for the importance of psychological empowerment for the job satisfaction of among nurses. Exploring the correlation between psychological empowerment and job satisfaction can provide guidelines and recommendation for the development of strategies to promote nurse retention and alleviate nursing shortage.

AB - The usefulness of stratum corneum neutrophil gelatinase-associated lipocalin and stratum corneum galectin-7 as biomarkers of acne vulgaris was studied. A comparison of neutrophil gelatinase-associated lipocalin levels on the cheeks of patients with acne vulgaris at the start of the study and at the time of symptom improvement showed a significant decrease. On the other hand, the galectin-7 levels at the time of symptom improvement were significantly higher than those at the start of the study. Therefore, because the inflammation in the epidermis and hair follicles was reduced after therapy, as a result of the solution of the inflammatory eruptions caused by acne vulgaris, the neutrophil gelatinase associated lipocalin level also showed a significant decrease after therapy. These results suggest that stratum corneum neutrophil gelatinase-associated lipocalin may be useful as an objective biomarker of changes in acne vulgaris symptoms.

PMID- 29473206 TI - Association of Mac-2-binding protein glycosylation isomer level with nutritional status in chronic liver disease. AB - BACKGROUND AND AIM: Mac-2-binding protein glycosylation isomer (M2BPGi) was recently identified as a serum glycobiomarker for liver fibrosis. However, the relationship between M2BPGi and malnutrition in patients with chronic liver disease (CLD) is unknown. We aimed to evaluate whether M2BPGi could be a surrogate marker for malnutrition in patients with CLD. METHODS: In total, 338 outpatients with CLD were enrolled (median age: 67 years). We evaluated the associations among liver fibrosis markers (M2BPGi, fibrosis-4 index, and aspartate aminotransferase-to-platelet count ratio index), Child-Pugh stages, and nutritional status markers. RESULTS: The median value (range) of serum M2BPGi levels was 0.94 cut-off index (COI) (0.22-11.57) in chronic hepatitis and Child Pugh A (n = 274), 4.775 COI (1.32-16.68) in Child-Pugh B (n = 46), and 11.37 COI (6.03-18.33) in Child-Pugh C (n = 18) (overall significance, P < 0.001). Serum M2BPGi levels showed a strong correlation with serum albumin concentration and controlling nutritional status score (rs = -0.649, P < 0.001 and rs = 0.671, P < 0.001, respectively). The correlations between M2BPGi and nutritional status markers were especially high in patients with hepatitis C virus infection and non B non-C hepatitis and patients with hepatocellular carcinoma. Among the three fibrosis markers, M2BPGi yielded the highest area under the receiver operating characteristic curve (0.920) for predicting hypoalbuminemia at an optimal cut-off value of 2.41 (sensitivity, 87.3%; specificity, 87.6%; P < 0.001). CONCLUSIONS: Serum M2BPGi levels are correlated with nutritional status markers in patients with CLD and could be a useful clinical marker of malnutrition.

PMID- 29473208 TI - The perpetual state of emergency that sacrifices protected areas in a changing climate. AB - A modern challenge for conservation biology is to assess the consequences of policies that adhere to assumptions of stationarity (e.g., historic norms) in an era of global environmental change. Such policies may result in unexpected and surprising levels of mitigation given future climate-change trajectories, especially as agriculture looks to protected areas to buffer against production losses during periods of environmental extremes. We assessed the potential impact of climate-change scenarios on the rates at which grasslands enrolled in the Conservation Reserve Program (CRP) are authorized for emergency harvesting (i.e., biomass removal) for agricultural use, which can occur when precipitation for the previous 4 months is below 40% of the normal or historical mean precipitation for that 4-month period. We developed and analyzed scenarios under the condition that policy will continue to operate under assumptions of stationarity, thereby authorizing emergency biomass harvesting solely as a function of precipitation departure from historic norms. Model projections showed the historical likelihood of authorizing emergency biomass harvesting in any given year in the northern Great Plains was 33.28% based on long-term weather records. Emergency biomass harvesting became the norm (>50% of years) in the scenario that reflected continued increases in emissions and a decrease in growing-season precipitation, and areas in the Great Plains with higher historical mean annual rainfall were disproportionately affected and were subject to a greater increase in emergency biomass removal. Emergency biomass harvesting decreased only in the scenario with rapid reductions in emissions. Our scenario-impact analysis indicated that biomass from lands enrolled in the CRP would be used primarily as a buffer for agriculture in an era of climatic change unless policy guidelines are adapted or climate-change projections significantly depart from the current consensus. PMID- 29473209 TI - Bendamustine-based conditioning prior to autologous stem cell transplantation (ASCT): Results of a French multicenter study of 474 patients from LYmphoma Study Association (LYSA) centers. AB - Carmustine shortage has led to an increase use of alternative conditioning regimens prior to autologous stem cell transplantation for the treatment of lymphoma, including Bendamustine-based (BeEAM). The aim of this study was to evaluate the safety of the BeEAM regimen in a large cohort of patients. A total of 474 patients with a median age of 56 years were analyzed. The majority of patients had diffuse large B-cell lymphoma (43.5%). Bendamustine was administered at a median dose of 197 mg/m2 /day (50-250) on days-7 and -6. The observed grade 1-4 toxicities included mucositis (83.5%), gastroenteritis (53%), skin toxicity (34%), colitis (29%), liver toxicity (19%), pneumonitis (5%), and cardiac rhythm disorders (4%). Nonrelapse mortality (NRM) was reported in 3.3% of patients. Acute renal failure (ARF) was reported in 132 cases (27.9%) (G >=2; 12.3%). Organ toxicities and death were more frequent in patients with post conditioning renal failure. In a multivariate analysis, pretransplant chronic renal failure, bendamustine dose >160 mg/m2 and age were independent prognostic factors for ARF. Pretransplant chronic renal failure, hyperhydration volume, duration of hyperhydration, and etoposide dose were predictive factors of NRM. A simple, four point scoring system can stratify patients by levels of risk for ARF and may allow for a reduction in the bendamustine dose to avoid toxicity. Drugs shortage may have dangerous consequences. Prospective, comparative studies are needed to confirm the toxicity/efficacy extents from this conditioning regimen compared to other types of high dose therapy.

PMID- 29473211 TI - Chiroptical spectroscopy and metabolomics for blood-based sensing of pancreatic cancer. AB - To enable the early diagnosis of pancreatic cancer, the search for and definition of reliable biomarkers remain a subject of great interest, with the specificity and sensitivity of the currently used biomarkers being below the required values. We tested a novel diagnostic approach for pancreatic cancer based on the specific molecular signature of blood plasma components. To acquire more detailed structural information, structure-sensitive chiroptical methods (electronic circular dichroism and Raman optical activity) were supplemented by conventional Raman and infrared spectroscopies. The obtained spectra were subsequently processed by linear discriminant analysis yielding high values of specificity and sensitivity. In addition, to monitor not only large biomolecules as potential biomarkers but also those of low molecular weight, we conducted an analysis of blood plasma samples by using metabolomics. The achieved results suggest a panel of promising biomarkers for a reliable detection of pancreatic cancer. PMID- 29473212 TI - Demographic, psychosocial, and behavioral associations with cancer screening among a homeless population. AB - BACKGROUND: Although cancer incidence and mortality is declining, cancer remains among the leading causes of death in the United States. Research shows that cancer morbidity and mortality can be reduced by early detection. Yet, both cancer risks and screening behavior remain understudied in the homeless population. METHODS: Researchers conducted a cross-sectional survey of homeless individuals (n = 201). The analysis describes the demographic, psychosocial, and behavioral associations with cancer screenings and knowledge of the lung cancer screening recommendation. RESULTS: Participants' mean age was 51.7 years (SD 13.6); the group was largely African American (77.3%) and male (67.9%). Among women, the breast and cervical cancer screening rates were 46.5% and 85.1%. Among men the prostate cancer screening rate was 34.2%. Among all participants, the colon cancer screening rate was 44%. Cancer risk behaviors were high. Lung cancer screening knowledge was low (23.0%). Some cancer screening behaviors were associated with age, income, health status, obesity, tobacco use, and physical activity. DISCUSSION: Despite higher cancer risk behaviors, knowledge and general participation rates for cancer screenings were below national benchmarks. CONCLUSION: To improve cancer survival among disparate populations, sustained community outreach is necessary to increase awareness of screening recommendations, identify high-risk individuals, and navigate them to resources. PMID- 29473213 TI - Ischemic colitis following left antegrade sclerotherapy for idiopathic varicocele. AB - The Tauber procedure, i.e., antegrade sclerotherapy for varicocele, can lead to ischemic colitis. The pathogenesis can involve an atypical systemic-portal communication, which could represent an infrequently reported (rare) anatomical variant. The aim of this study is to review clinical cases from the literature to highlight the anatomical bases of such complications. A computer-aided and hand checked review of the literature was used to identify relevant publications. Also, the computed tomography (CT) examination of a clinical case with medico legal implications due to severe vascular complication following Tauber's procedure was reviewed. Although specific references to this complication have appeared since the 19th century, reports in the contemporary literature include only a few clinical cases of ischemic colitis following Tauber's procedure. The CT scan images of a filed lawsuit revealed traces suggesting a significant communication between the testicular and left colic veins, forming part of the systemic-portal anastomoses. An anatomical variation consisting of a communication between the testicular and left colic veins has been described from the clinical point of view, corresponding to a significant anatomical finding identified in the past that has been under-reported and its clinical importance subsequently underestimated. For the first time we have demonstrated its pathophysiological significance in a real clinical scenario, linking the anatomical variation to the clinical complication. This demonstrates the importance of raising scientific awareness on this issue to prevent possibly devastating complications in daily clinical practice. Clin. Anat. 31:774-781, 2018.

AB - Primary cutaneous aspergillosis is a rare, life-threatening fungal infection in premature infants. We report a case of primary cutaneous aspergillosis caused by Aspergillus tamarii in an extremely low birthweight infant. The infant was delivered by cesarean section with complications from an intrauterine infection, brain intraventricular hemorrhage, tension pneumothorax and cardiac tamponade. On the 12th day of life, he developed erythematous maceration with erosion on his back. Septate hyphae were detected on two occasions from specimens of the skin lesion. The manifestations of the colony and slide culture showed the characteristics of A. tamarii. The nucleotide sequences of internal transcribed spacer regions of the ribosomal RNA gene, partial sequences of beta-tubulin and calmodulin gene were compatible with those of A. tamarii. Of the known Aspergillus species, Aspergillus fumigatus and Aspergillus flavus have been reported in previous studies as the major causative agents in primary cutaneous aspergillosis, whereas human infection by A. tamarii is rare. We consider that A. tamarii is important as an unusual opportunistic human pathogen among premature infants. PMID- 29473216 TI - Homeostatic control of dendritic cell numbers and differentiation. AB - Dendritic cells (DCs) are a diverse family of cells that play a crucial role in linking our innate and adaptive immune system to initiate adequate T-cell responses. They respond to pathogens by triggering the appropriate adaptive immune response that is required to clear invaders while balancing the need to limit tissue damage as a result of inflammation. Perturbation in DC regulation results in abnormal T-cell homeostasis, leading to development of autoimmune diseases and aberrant responses to pathogens. In recent years, it has become clear that the DC family is more complex than initially thought in terms of their identification, homeostasis and functions. In this review, we discuss recent findings that improve our understanding of development, and functional specializations of conventional and plasmacytoid DCs. PMID- 29473217 TI - A subband Steiglitz-McBride algorithm for automatic analysis of FID data. AB - Fast, accurate, and automatic extraction of parameters of nuclear magnetic resonance free induction decay (FID) signal for chemical spectroscopy is a challenging problem. Recently, the Steiglitz-McBride algorithm has been shown to exhibit superior performance in terms of speed, accuracy, and automation when applied to the extraction of T2 relaxation parameters for myelin water imaging of brain. Applying it to FID data reveals that it falls short of the second objective, the accuracy. Especially, it struggles with the issue of missed spectral peaks when applied to chemical samples with relatively dense frequency spectra. To overcome this issue, a preprocessing stage of subband decomposition is proposed before the application of Steiglitz-McBride algorithm to the FID signal. It is demonstrated that by doing so, a considerable improvement in accuracy is achieved. But this is not gained at the cost of the first objective, the speed. An adaptive subband decomposition is employed in conjunction with the Bayesian information criteria to carry out an efficient decomposition according to spectral content of the signal under investigation. Furthermore, adaptive subband decomposition and the Bayesian information criteria also serve to make the resulting algorithm independent of user input, which also fulfills the third objective, the automation. This makes the proposed algorithm favorable for fast, accurate, and automatic extraction of FID signal parameters. PMID- 29473219 TI - Soft-tissue dehiscence coverage at peri-implant sites. AB - Soft-tissue dehiscence at the facial aspect of an osteointegrated implant is a common complication which impacts on the final esthetic result. The etiology and ways of diagnosing this condition are still controversial. Many factors seem to influence the position of the peri-implant soft-tissue margin, and some of these have been studied more carefully than others. Various surgical and combination surgical-prosthetic approaches have been described to treat soft-tissue dehiscence, with the latter appearing to be more predictable. This paper focuses on the factors affecting peri-implant soft-tissue margins and describes the different treatment approaches, reported in the literature, to treat buccal soft tissue dehiscence, with more focus on the prosthetic-surgical-prosthetic approach. PMID- 29473220 TI - Cost shifting and other perverse incentives in biodiversity offsetting in India. AB - Biodiversity offsetting aims to compensate for development-induced biodiversity loss through commensurate conservation gains and is gaining traction among governments and businesses. However, cost shifting (i.e., diversion of offset funds to other conservation programs) and other perverse incentives can undermine the effectiveness of biodiversity offsetting. Additionality-the requirement that biodiversity offsets result in conservation outcomes that would not have been achieved otherwise-is fundamental to biodiversity offsetting. Cost shifting and violation of additionality can go hand in hand. India's national offsetting program is a case in point. Recent legislation allows the diversion of offset funds to meet the country's preexisting commitments under the United Nations Framework Convention on Climate Change (UNFCCC) and United Nations Convention on Biological Diversity (CBD). With such diversions, no additional conservation takes place and development impacts remain uncompensated. Temporary additionality cannot be conceded in light of paucity of funds for preexisting commitments unless there is open acknowledgement that fulfillment of such commitments is contingent on offset funds. Two other examples of perverse incentives related to offsetting in India are the touting of inherently neutral offsetting outcomes as conservation gains, a tactic that breeds false complacency and results in reduced incentive for additional conservation efforts, and the clearing of native vegetation for commercial plantations in the name of compensatory afforestation, a practice that leads to biodiversity decline. The risks accompanying cost shifting and other perverse incentives, if not preempted and addressed, will result in net loss of forest cover in India. We recommend accurate baselines, transparent accounting, and open reporting of offset outcomes to ensure biodiversity offsetting achieves adequate and additional compensation for impacts of development. PMID- 29473218 TI - NGF steers microglia toward a neuroprotective phenotype. AB - Microglia are the sentinels of the brain but a clear understanding of the factors that modulate their activation in physiological and pathological conditions is still lacking. Here we demonstrate that Nerve Growth Factor (NGF) acts on microglia by steering them toward a neuroprotective and anti-inflammatory phenotype. We show that microglial cells express functional NGF receptors in vitro and ex vivo. Our transcriptomic analysis reveals how, in primary microglia, NGF treatment leads to a modulation of motility, phagocytosis and degradation pathways. At the functional level, NGF induces an increase in membrane dynamics and macropinocytosis and, in vivo, it activates an outward rectifying current that appears to modulate glutamatergic neurotransmission in nearby neurons. Since microglia are supposed to be a major player in Abeta peptide clearance in the brain, we tested the effects of NGF on its phagocytosis. NGF was shown to promote TrkA-mediated engulfment of Abeta by microglia, and to enhance its degradation. Additionally, the proinflammatory activation induced by Abeta treatment is counteracted by the concomitant administration of NGF. Moreover, by acting specifically on microglia, NGF protects neurons from the Abeta-induced loss of dendritic spines and inhibition of long term potentiation. Finally, in an ex-vivo setup of acute brain slices, we observed a similar increase in Abeta engulfment by microglial cells under the influence of NGF. Our work substantiates a role for NGF in the regulation of microglial homeostatic activities and points toward this neurotrophin as a neuroprotective agent in Abeta accumulation pathologies, via its anti-inflammatory activity on microglia. PMID- 29473221 TI - Supplementation of broiler diets with high levels of microbial protease and phytase enables partial replacement of commercial soybean meal with raw, full-fat soybean. AB - A 3 * 3 + 1 factorial, involving three levels of protease (0, 15,000 or 30,000 PROT/kg) and three levels of phytase (1,000, 2,000 or 3,000 FYT/kg), was used to evaluate the effect of replacing commercial soybean meal (SBM) with raw, full-fat soybean (RFSB) at 75 g/kg of diet for broilers. A control diet was used for comparison. Each treatment was replicated six times, with nine birds per replicate. The concentration of trypsin inhibitors (TIs) in the test diets was approximately 10,193.4 TIU/kg. Regardless of enzyme supplementation, feed intake (FI) and body weight gain (BWG) of birds in the control group were superior to those on the test diets. Birds that received the protease-free test diets had reduced FI and BWG, but when supplemented with protease, were similar to the control diet in BWG, FI (except 0-35 days) and feed conversion ratio (FCR). When the test diet was supplemented with elevated levels (extradose) of protease and phytase, the BWG was improved during 0-10 days (p = .05) and 0-24 days (p < .01). Regardless of protease supplementation, the weight of thighs was lower for birds fed the test diets. Birds that received the control diet had smaller weight of pancreas. Increasing the level of phytase supplementation reduced (p < .05) the weight of the pancreas. The apparent ileal digestibility (AID) of CP and AA was higher in birds on the control diets, but this was also improved in test diets by protease supplementation. The activities of trypsin (7%), general proteolytic (11%) and lipase (12%) were slightly increased because of protease supplementation. Mucosal depth and apparent villus surface areas were increased by about 2.9% and 20%, respectively, due to supplementation of elevated level of phytase. It can be concluded that RFSB could partially replace SBM in broiler diets, provided the diets are supplemented with elevated levels of protease and phytase. PMID- 29473222 TI - Assessing a portable, real-time display handheld meter with UV-A and UV-B sensors for potential application in personal sun exposure studies. AB - BACKGROUND: Observing accurate real-time measurements of solar ultraviolet radiation (UVR) levels is important since personal excess sun exposure is associated with skin cancers. Handheld measurement devices may be helpful but their accuracy is unknown. We compare a portable, science-grade solar UVR monitoring device against two fixed, science-grade solar UVR instruments. METHODS: Instruments were (1) a fixed Solar Light 501 UV-B biometer to measure UV B; (2) a fixed Kipp and Zonen radiometer used to measure UV-A and UV-B; and (3) Goldilux ultraviolet probes which are commercially available portable devices. Two different probes were used, one measured UV-A and the other UV-B radiation. The Goldilux probes were levelled and secured next to the UV-B biometer. Between 10:00 and 14:40 UTC+2, the UV-B biometer was set to record at 10-minute intervals and measurements by the Goldilux probes were manually taken simultaneously. Results were compared for all data and by solar zenith angle (SZA) ranges. RESULTS: The Goldilux UV-B probe measured UV-B relatively well in its diurnal pattern, however, its readings were ~77% higher than those made by the UV-B biometer. While UV-A measurements from the Goldilux UV-A probe and those from the radiometer were in relatively good agreement in pattern, the radiometer read ~47% higher than the Goldilux UV-A probe. UV-B data from Goldilux UV-B probe had a moderately strong correlation with UV-B biometer data for small SZAs; conversely, for UV-A, the Goldilux UV-A probe had a strong correlation with the UV-A radiometer data for large SZAs. CONCLUSION: Handheld devices may be useful to provide real-time readings of solar UVR patterns, however, to achieve synchronicity in the magnitude of readings to those made by science-grade fixed instruments, devices may need to be used during certain times of the day and in clear-sky conditions which may not be practical in personal exposure studies. PMID- 29473223 TI - Epicrestal and subcrestal placement of platform-switched implants: 18 month result of a randomized, controlled, split-mouth, prospective clinical trial. AB - OBJECTIVES: To evaluate the changes in marginal bone levels (MBL) and soft tissue dimension around platform-switched implants with the implant-abutment junction (IAJ) placed at the crest or 1.5-2 mm subcrestally. MATERIALS AND METHODS: In all, 96 platform-switched implants were placed in either the posterior maxilla or mandible in 48 partially edentulous patients in a split-mouth study. All implants were provisionally restored after 4-5 months and definitively after 6 months (T6). Radiographic assessment of MBL was assessed at implant placement (T0), T6, 12 months (T12), and 18 months (T18) after placement. Mid-buccal soft tissue and papilla measurements were performed at T6, T12, and T18. RESULTS: In all, 43 patients with 86 implants completed the study. The T18 examination showed an implant survival rate of 100% in both groups. Analysis showed that MBL varied as a function of IAJ location, which indicated more coronal bone levels with subcrestal (2.39 +/- 0.08 mm) than with epicrestal placements (0.88 +/- 0.08 mm) (p < .05). Greater average marginal bone loss was found in the subcrestal group (0.40 +/- 0.07 mm) compared to the epicrestal group (0.13 +/- 0.08 mm) although no statistically significant difference was found at T18 (p > .05). Levels of mid buccal soft tissue had no significant changes over time, regardless of group (p > .05). There was a significant difference in increase in papilla between T6 and T12 and T18 (p = .005 and .001), but not between T12 and T18 (p = .61). These papilla levels and changes were similar between groups (p > .05). CONCLUSIONS: The MBL changes around platform-switched implants with same geometry were not affected by the epicrestal or subcrestal location of the IAJ. Furthermore, the location of the IAJ did not affect the implant survival and soft tissue dimensions. However, no bone loss was located apical to the IAJ when the implants were placed subcrestally.

AB - tert-Butylphosphonic acid and lanthanide precursors were employed to construct two high-nuclearity hybrid silver(I)-ytterbium(III) phosphonate clusters: compound 1 consists of a Ag16 ethynide cluster fused with a trinuclear hydroxoytterbium phosphonate cluster, whereas compound 2 is composed of two Ag16 ethynide clusters bridged by a hexanuclear oxo/hydroxoytterbium phosphonate cluster. Using transition-metal-substituted lacunary polyoxotungstates in place of the lanthanide reactant, new phosphonate-functionalized silver(I)-copper(II) ethynide clusters [Ag34 Cu6 (3) and Ag37 Cu6 (4)] and silver(I) ethynide clusters [Ag51 (5) and Ag72 (6)] were obtained. The structures of complexes 3-6 feature core-shell arrangements, in which silver(I)-copper(II) or silver(I) ethynide cluster shells stabilized by peripheral phosphonate ligands enclose different kinds of tungstate core templates. PMID- 29473226 TI - Infiltrative lamina propria invasion pattern as an independent predictor for cancer-specific and overall survival of instillation treatment-naive stage T1 high-grade urothelial bladder cancer. AB - OBJECTIVES: To investigate established prognostic factors and relatively new histopathological tumor characteristics including metric substage and lamina propria invasion patterns in a large series of T1 high-grade non-muscle-invasive bladder cancer. METHODS: Between 1989 and 2012, 322 patients with initial stage T1 high-grade bladder cancer underwent transurethral resection, followed by re transurethral resection and a conservative approach with follow-up regime alone or instillation treatment. Transurethral resection specimens were reassessed by two experienced urological pathologists for tumor grade according to the World Health Organization 1973 classification, metric T1 substage, lamina propria invasion pattern and associated carcinoma in situ. The median follow-up period was 42 months (interquartile range 25-72 months). In addition to Kaplan-Meier analyses, uni- and multivariable Cox regression analyses were used to compare progression-free survival, cancer-specific survival and overall survival for the studied parameters comparing two subcohorts. RESULTS: While in patients after instillation treatment no examined feature was shown as an independent predictor for prognosis, there were predictive histopathological features in multivariable Cox regression analyses in instillation treatment-naive patients: associated carcinoma in situ (hazard ratio 2.278, 95% confidence interval 1.119-4.634, P = 0.023) and World Health Organization 1973 grade 3 (hazard ratio 2.950, 95% confidence interval 1.021-8.536, P = 0.046) for worse progression-free survival, infiltrative lamina propria tumor pattern for worse cancer-specific survival (hazard ratio 2.369, 95% confidence interval 1.034-5.429, P = 0.042) and overall survival (hazard ratio 1.049, 95% confidence interval 1.024-1.075, P = 0.001). CONCLUSIONS: The results of the present T1 high-grade bladder cancer series suggest that lamina propria invasion pattern is a promising parameter to predict the prognosis of T1 high-grade bladder cancer in an instillation treatment-naive subcohort. Prospective multicenter evaluations are warranted. The need for instillation treatment in T1 high-grade bladder cancer is clearly demanded. PMID- 29473227 TI - Amorphizing of Cu Nanoparticles toward Highly Efficient and Robust Electrocatalyst for CO2 Reduction to Liquid Fuels with High Faradaic Efficiencies. AB - Conversion of carbon dioxide (CO2 ) into valuable chemicals, especially liquid fuels, through electrochemical reduction driven by sustainable energy sources, is a promising way to get rid of dependence on fossil fuels, wherein developing of highly efficient catalyst is still of paramount importance. In this study, as a proof-of-concept experiment, first a facile while very effective protocol is proposed to synthesize amorphous Cu NPs. Unexpectedly, superior electrochemical performances, including high catalytic activity and selectivity of CO2 reduction to liquid fuels are achieved, that is, a total Faradaic efficiency of liquid fuels can sum up to the maximum value of 59% at -1.4 V, with formic acid (HCOOH) and ethanol (C2 H6 O) account for 37% and 22%, respectively, as well as a desirable long-term stability even up to 12 h. More importantly, this work opens a new avenue for improved electroreduction of CO2 based on amorphous metal catalysts. PMID- 29473228 TI - Evaluating methods for extraction of alpha-cellulose from leaves of Melaleuca quinquenervia for stable carbon and oxygen isotope analysis. AB - RATIONALE: Purification of alpha-cellulose from plant tissues is commonly conducted to facilitate the reliable measurement of stable isotope ratios. Prior research has shown that different plant species and tissues react differently to standardised cellulose extraction techniques. Thus, no single method can be applied to all materials and careful consideration must be undertaken when selecting an extraction technique. METHODS: In order to evaluate their suitability for use on Melaleuca quinquenervia leaves, a suite of eight different cellulose extraction techniques were tested. Leaves of this species are preserved in perched lakes on southeast Queensland's sand islands and are a focus of ongoing palaeoclimate research. Elemental analyser/isotope ratio mass spectrometry was used to measure stable carbon and oxygen isotopic ratios and sample composition was measured using Fourier transform infrared spectroscopy. RESULTS: We demonstrate that the standard Brendel extraction technique, particularly with a higher reagent volume and longer boiling time, produces cellulose with the lowest spread in isotopic ratios among replicates, and with the fewest impurities detected by Fourier transform infrared spectroscopy. We also show that pre-treating the leaves to extract leaf wax lipids in order to enable paired analysis from the same sub-fossil leaves does not significantly affect the quality of the isotopic results. CONCLUSIONS: The standard Brendel method allows the most precise stable carbon and oxygen information to be retrieved from the leaves of M. quinquenervia. This unlocks the potential to study palaeoclimate proxy records from our study site and potentially throughout the natural range of the species across eastern Australia, Papua New Guinea and New Caledonia. PMID- 29473229 TI - Follicular fluid stimulates capacitation and acrosome reaction in alpaca sperm (Vicugna pacos). AB - The follicular fluid exerts an effect on the sperm capacitation of several species; however, these effects vary according to species, both in the sperm motility and in the subsequent acrosome reaction. In this study, the effect of alpaca follicular fluid (aFF) on the motility and acrosome reaction of alpaca spermatozoa was observed, using follicular fluid of three follicle sizes: small (<3 mm), medium (3-6 mm) and large (>6 mm), in a concentration of 30%. Sperm motility at the first hour of incubation with aFF of small follicles was 48.0%, with aFF of medium follicles it was 43.33% and with aFF of large follicles, it was 34.53%, while control averaged 26.00%. At the second hour, control achieved an average of 28.13%, treatment with aFF from small follicles showed an average of 46.53%, with aFF from medium follicles it was 40.00% and with aFF from large follicles it was 35.60%. The acrosome reaction after 4 hours of incubation was 30.06% for control, whereas for aFF of small follicles it was 66.3%, with aFF of medium follicles it was 58.86% and for aFF of large follicles, it was 67.63%. In the case of sperm motility, a significant difference is demonstrated for all treatments in relation to the control at the first hour, whereas only the treatments with aFF of small and medium follicles show a significant difference with respect to the control at the second hour. In the case of the acrosome reaction, all treatments with follicular fluid show a significant difference with respect to the control. It was concluded that alpaca follicular fluid favours sperm capacitation and the acrosome reaction in alpaca spermatozoa. PMID- 29473231 TI - Quantum Emitters in Hexagonal Boron Nitride Have Spectrally Tunable Quantum Efficiency. AB - Understanding the properties of novel solid-state quantum emitters is pivotal for a variety of applications in research fields ranging from quantum optics to biology. Recently discovered defects in hexagonal boron nitride are especially interesting, as they offer much desired characteristics such as narrow emission lines and photostability. Here, the dependence of the emission on the excitation wavelength is studied. It is found that, in order to achieve bright single-photon emission with high quantum efficiency, the excitation wavelength has to be matched to the emitter. This is a strong indication that the emitters possess a complex level scheme and cannot be described by a simple two or three-level system. Using this excitation dependence of the emission, further insight to the internal level scheme is gained and it is demonstrated how to distinguish different emitters both spatially as well as in terms of their photon correlations.

AB - Extracellular vesicles (EVs) have recently gained significant attention as important mediators of intercellular communication, potential drug carriers, and disease biomarkers. These natural cell-derived nanoparticles are postulated to be biocompatible, stable under physiological conditions, and to show reduced immunogenicity as compared to other synthetic nanoparticles. Although initial clinical trials are ongoing, the use of EVs for therapeutic applications may be limited due to undesired off-target activity and potential "dilution effects" upon systemic administration which may affect their ability to reach their target tissues. To fully exploit their therapeutic potential, EVs are embedded into implantable biomaterials designed to achieve local delivery of therapeutics taking advantage of enzyme prodrug therapy (EPT). In this first application of EVs for an EPT approach, EVs are used as smart carriers for stabilizing enzymes in a hydrogel for local controlled conversion of benign prodrugs to active antiinflammatory compounds. It is shown that the natural EVs' antiinflammatory potential is comparable or superior to synthetic carriers, in particular upon repeated long-term incubations and in different macrophage models of inflammation. Moreover, density-dependent color scanning electron microscopy imaging of EVs in a hydrogel is presented herein, an impactful tool for further understanding EVs in biological settings.

AB - For a series of neutral [2]rotaxanes consisting of a pillar[5]arene ring and axles possessing two stations separated by flexible spacers of different lengths, the free energies of activation for the ring shuttling between the stations were found to be independent of the spacer length. The constitution of the spacer affects the activation energies: replacement of CH2 groups by repulsive oxygen atoms in the axle increases the barrier. The explanation for the observed length independence lies in the presence of a barrier for re-forming the stable co conformation, which makes the ring travel back and forth along the thread in an intermediate state. PMID- 29473233 TI - Highly Augmented Drug Loading and Stability of Micellar Nanocomplexes Composed of Doxorubicin and Poly(ethylene glycol)-Green Tea Catechin Conjugate for Cancer Therapy. AB - Low drug loading and instability in blood circulation are two key challenges that impede the successful clinical translation of nanomedicine, as they result in only marginal therapeutic efficacy and toxic side effects associated with premature drug leakage, respectively. Herein, highly stable and ultrahigh drug loading micellar nanocomplexes (MNCs) based on the self-assembly of the anticancer drug doxorubicin (DOX) and a poly(ethylene glycol)-epigallocatechin-3 O-gallate (EGCG) conjugate are developed. The formation of these MNCs is facilitated by strong favorable intermolecular interactions between the structurally similar aromatic EGCG and DOX molecules, which impart exceptionally high drug-loading capability of up to 88% and excellent thermodynamic and kinetic stability. Unlike two clinical formulations of DOX-free DOX and liposomal DOX, which are not effective below their lethal dosages, these DOX-loaded MNCs demonstrate significant tumor growth inhibition in vivo on a human liver cancer xenograft mouse model with minimal unwanted toxicity. Overall, these MNCs can represent a safe and effective strategy to deliver DOX for cancer therapy. PMID- 29473234 TI - Direct Growth of Highly Stable Patterned Graphene on Dielectric Insulators using a Surface-Adhered Solid Carbon Source. AB - A novel method is described for the direct growth of patterned graphene on dielectric substrates by chemical vapor deposition (CVD) in the presence of Cu vapor and using a solid aromatic carbon source, 1,2,3,4-tetraphenylnapthalene (TPN), as the precursor. The UV/O3 treatment of the TPN film both crosslinks TPN and results in a strong interaction between the substrate and the TPN that prevents complete sublimation of the carbon source from the substrate during CVD. Substrate-adhered crosslinked TPN is successfully converted to graphene on the substrate without any organic contamination. The graphene synthesized by this method shows excellent mechanical and chemical stability. This process also enables the simultaneous patterning of graphene materials, which can thus be used as transparent electrodes for electronic devices. The proposed method for the synthesis directly on substrates of patterned graphene is expected to have wide applications in organic and soft hybrid electronics. PMID- 29473236 TI - Oxide Thin-Film Electronics using All-MXene Electrical Contacts. AB - 2D MXenes have shown great promise in electrochemical and electromagnetic shielding applications. However, their potential use in electronic devices is significantly less explored. The unique combination of metallic conductivity and hydrophilic surface suggests that MXenes can also be promising in electronics and sensing applications. Here, it is shown that metallic Ti3 C2 MXene with work function of 4.60 eV can make good electrical contact with both zinc oxide (ZnO) and tin monoxide (SnO) semiconductors, with negligible band offsets. Consequently, both n-type ZnO and p-type SnO thin-film transistors (TFTs) have been fabricated entirely using large-area MXene (Ti3 C2 ) electrical contacts, including gate, source, and drain. The n- and p-type TFTs show balanced performance, including field-effect mobilities of 2.61 and 2.01 cm2 V-1 s-1 and switching ratios of 3.6 * 106 and 1.1 * 103 , respectively. Further, complementary metal oxide semiconductor (CMOS) inverters are demonstrated. The CMOS inverters show large voltage gain of 80 and excellent noise margin of 3.54 V, which is 70.8% of the ideal value. Moreover, the operation of CMOS inverters is shown to be very stable under a 100 Hz square waveform input. The current results suggest that MXene (Ti3 C2 ) can play an important role as contact material in nanoelectronics. PMID- 29473235 TI - Caveolin 3-dependent loss of t-tubular ICa during hypertrophy and heart failure in mice. AB - NEW FINDINGS: What is the central question of this study? Heart failure is associated with redistribution of L-type Ca2+ current (ICa ) away from the t tubule membrane to the surface membrane of cardiac ventricular myocytes. However, the underlying mechanism and its dependence on severity of pathology (hypertrophy versus failure) are unclear. What is the main finding and its importance? Increasing severity of response to transverse aortic constriction, from hypertrophy to failure, was accompanied by graded loss of t-tubular ICa and loss of regulation of ICa by caveolin 3. Thus, the pathological loss of t-tubular ICa , which contributes to impaired excitation-contraction coupling and thereby cardiac function in vivo, appears to be attributable to loss of caveolin 3 dependent stimulation of t-tubular ICa . ABSTRACT: Previous work has shown redistribution of L-type Ca2+ current (ICa ) from the t-tubules to the surface membrane of rat ventricular myocytes after myocardial infarction. However, whether this occurs in all species and in response to other insults, the relationship of this redistribution to the severity of the pathology, and the underlying mechanism, are unknown. We have therefore investigated the response of mouse hearts and myocytes to pressure overload induced by transverse aortic constriction (TAC). Male C57BL/6 mice underwent TAC or equivalent sham operation 8 weeks before use. ICa and Ca2+ transients were measured in isolated myocytes, and expression of caveolin 3 (Cav3), junctophilin 2 (Jph2) and bridging integrator 1 (Bin1) was determined. C3SD peptide was used to disrupt Cav3 binding to its protein partners. Some animals showed cardiac hypertrophy in response to TAC with little evidence of heart failure, whereas others showed greater hypertrophy and pulmonary congestion. These graded changes were accompanied by graded cellular hypertrophy, t-tubule disruption, decreased expression of Jph2 and Cav3, and decreased t-tubular ICa density, with no change at the cell surface, and graded impairment of Ca2+ release at t-tubules. C3SD decreased ICa density in control but not in TAC myocytes. These data suggest that the graded changes in cardiac function and size that occur in response to TAC are paralleled by graded changes in cell structure and function, which will contribute to the impaired function observed in vivo. They also suggest that loss of t-tubular ICa is attributable to loss of Cav3-dependent stimulation of ICa . PMID- 29473237 TI - Dietary outcomes of overweight fathers and their children in the Healthy Dads, Healthy Kids community randomised controlled trial. AB - BACKGROUND: Few studies have examined dietary intake changes following a weight loss intervention in fathers and the association between father-child dietary intakes. The present study aimed to: (i) evaluate the change in dietary intake in overweight fathers randomised to a family-based lifestyle intervention [Healthy Dads Healthy Kids (HDHK)] versus controls and (ii) investigate whether an association exists between father-child dietary intakes. METHODS: A secondary analysis was conducted of father-child baseline and 3-month post-intervention data (n = 93) collected in the HDHK community randomised controlled trial. Intention-to-treat linear mixed models were used to assess dietary changes by group, time (baseline and 3-month) and the group-by-time interaction. Cohens d was used to determine effect sizes. RESULTS: Significant group-by-time effects (all P < 0.05) favouring fathers in the intervention group were identified for total daily energy intake (-1956 kJ, d = 0.74), total sugars (-45 g, d = 0.63), sodium (-414 mg, d = 0.58) and % energy from nutrient-dense, core foods (+10.1%, d = 0.86), fruit (+2.4%, d = 0.71), vegetarian protein sources (+1.2%, d = 0.57), pre-packed snacks (+1.7%, d = 0.58) and sugar-sweetened beverages (-4.1%, d = 0.58). At baseline, positive correlations were observed between father-child intakes for a number of dietary variables, and significant correlations were observed between father-child change scores for % energy carbohydrate (r = 0.35, P = 0.023), % energy from fruit (r = 0.47, P = 0.002), vegetarian protein sources (r = 0.46, P = 0.002) and frequency of consuming meals with vegetables (r = 0.38, P = 0.012). CONCLUSIONS: The HDHK intervention successfully improved some aspects of father's dietary intakes compared to controls. The fathers' eating patterns also correlated with those of their children for several dietary variables. These novel data suggest that fathers can be targeted as agents of dietary change within obesity prevention and treatment programmes. PMID- 29473238 TI - eHealth readiness of dietitians. AB - BACKGROUND: The present study aimed to determine the eHealth readiness and changes over time of dietitians in Australia. METHODS: Two cross-sectional analyses of Australian dietitians were conducted in 2013 and 2016, using a survey adapted from one conducted in 2011 by the US Academy of Nutrition and Dietetics. The survey encompassed 30 questions on eHealth readiness across five dimensions: access, standards, attitude, aptitude and advocacy. Descriptive statistics, independent t-tests, chi-squared tests and Z-tests were computed to compare responses from the 2013 and 2016 surveys. RESULTS: The survey completion rate represented 14.5% (747) of the Dietitians Association of Australia members in 2013 and 8% (417) in 2016. The survey responses in relation to access and standards suggest that dietitians are well positioned for eHealth. For attitude and aptitude, there is a moderate level of preparedness, with minor improvements over time. Although showing significant improvement (P < 0.05), advocacy highlights the area requiring the most development because the majority of dietitians (61%) reported 'no role' in eHealth solutions. CONCLUSIONS: Dietitians are progressing in relation to access, attitudinal and aptitudinal readiness for eHealth, although they rate poorly with respect to advocacy readiness. It was concluded that dietitians are not yet ready, and also that valuable opportunities to achieve the benefits that eHealth can deliver will be missed, if dietitians do not take the lead in guiding the development, selection and implementation of nutrition-related technologies. Strengthening the dimension of advocacy and ensuring collaboration across the profession, drawing on the varying expertise demonstrated across the practice areas and by the different generations, will be central to improving dietitian eHealth readiness.

PMID- 29473240 TI - Loss of PPM1F expression predicts tumour recurrence and is negatively regulated by miR-590-3p in gastric cancer. AB - OBJECTIVES: MicroRNAs (miRNAs) as small non-coding RNA molecules act by negatively regulating their target genes. Recent studies have shown that protein phosphatase Mg2+/Mn2+-dependent 1F (PPM1F) plays a critical role in cancer metastasis. But, the regulation mechanisms of PPM1F by miRNAs in gastric cancer (GC) remain undefined. METHODS: The correlation of PPM1F or miR-590-3p (miR-590) expression with clinicopathological features and prognosis of the patients with GC was analysed by TCGA RNA-sequencing data. The miRNAs that target PPM1F gene were identified by bioinformatics and Spearman correlation analysis, and the binding site between miR-590 and PPM1F 3'UTR was confirmed by dual luciferase assay. MTT and Transwell assays were conducted to evaluate the effects of miR-590 or (and) PPM1F on cell proliferation and invasion. RESULTS: We found that PPM1F expression was downregulated in GC tissues and cell lines and was correlated with tumour recurrence in patients with GC. The decreased expression of PPM1F was attributed to the dysregulation of miR-590 expression rather than its genetic or epigenetic alterations. Overexpression of miR-590 promoted cell proliferation and invasion capability of GC cells, while knockdown of miR-590 reversed these effects. Moreover, PPM1F was validated as a direct target of miR-590 and counteracted the tumour-promoting effects caused by miR-590. The expression of miR-590 presented the negative correlation with PPM1F expression and acted as an independent prognostic factor for tumour recurrence in patients with GC. CONCLUSION: PPM1F may function as a suppressive factor and is negatively regulated by miR-590 in GC. PMID- 29473242 TI - The genomic footprint of climate adaptation in Chironomus riparius. AB - The gradual heterogeneity of climatic factors poses varying selection pressures across geographic distances that leave signatures of clinal variation in the genome. Separating signatures of clinal adaptation from signatures of other evolutionary forces, such as demographic processes, genetic drift and adaptation, to nonclinal conditions of the immediate local environment is a major challenge. Here, we examine climate adaptation in five natural populations of the harlequin fly Chironomus riparius sampled along a climatic gradient across Europe. Our study integrates experimental data, individual genome resequencing, Pool-Seq data and population genetic modelling. Common-garden experiments revealed significantly different population growth rates at test temperatures corresponding to the population origin along the climate gradient, suggesting thermal adaptation on the phenotypic level. Based on a population genomic analysis, we derived empirical estimates of historical demography and migration. We used an FST outlier approach to infer positive selection across the climate gradient, in combination with an environmental association analysis. In total, we identified 162 candidate genes as genomic basis of climate adaptation. Enriched functions among these candidate genes involved the apoptotic process and molecular response to heat, as well as functions identified in studies of climate adaptation in other insects. Our results show that local climate conditions impose strong selection pressures and lead to genomic adaptation despite strong gene flow. Moreover, these results imply that selection to different climatic conditions seems to converge on a functional level, at least between different insect species. PMID- 29473241 TI - Immunohistochemical assessment of Survivin and Bcl3 expression as potential biomarkers for NF-kappaB activation in the Barrett metaplasia-dysplasia adenocarcinoma sequence. AB - Non-dysplastic Barrett's oesophagus (NDBE) occurs as a consequence of an inflammatory response triggered through prolonged gastro-oesophageal reflux and it may precede the development of oesophageal adenocarcinoma. NF-kappaB activation as a result of the inflammatory response has been shown in NDBE, but the possible mechanism involved in the process is unknown. The aim of this study was to assess, using immunohistochemistry, Survivin and Bcl3 expression as potential biomarkers for NF-kappaB activation along the oesophageal metaplasia dysplasia-adenocarcinoma sequence. Survivin is an NF-kappaB-inducible anti apoptotic protein, and Bcl3 is a negative regulator of NF-kappaB. There was progressive upregulation of Survivin expression along the oesophageal metaplasia dysplasia-adenocarcinoma sequence. Bcl3 expression was upregulated in non dysplastic Barrett's oesophagus, low-grade, high-grade dysplasia and oesophageal adenocarcinoma when compared to squamous group. The study shows the differential expression of Bcl3 between the squamous and Barrett's stage, suggesting that Bcl3 could be a surrogate marker for early event involving constitutive NF-kappaB activation. In addition, the study suggests that NF-kappaB activation may infer resistance to apoptosis through the expression of anti-apoptotic genes such as Survivin, which showed progressive increase in expression throughout the oesophageal metaplasia-dysplasia-adenocarcinoma sequence. This ability to avoid apoptosis may underlie the persistence and malignant predisposition of Barrett's metaplasia. PMID- 29473243 TI - Development and validation of an algorithm for the study of sleep using a biometric shirt in young healthy adults. AB - Portable polysomnography is often too complex and encumbering for recording sleep at home. We recorded sleep using a biometric shirt (electrocardiogram sensors, respiratory inductance plethysmography bands and an accelerometer) in 21 healthy young adults recorded in a sleep laboratory for two consecutive nights, together with standard polysomnography. Polysomnographic recordings were scored using standard methods. An algorithm was developed to classify the biometric shirt recordings into rapid eye movement sleep, non-rapid eye movement sleep and wake. The algorithm was based on breathing rate and heart rate variability, body movement, and included a correction for sleep onset and offset. The overall mean percentage of agreement between the two sets of recordings was 77.4%; when non rapid eye movement and rapid eye movement sleep epochs were grouped together, it increased to 90.8%. The overall kappa coefficient was 0.53. Five of the seven sleep variables were significantly correlated. The findings of this pilot study indicate that this simple portable system could be used to estimate the general sleep pattern of young healthy adults. PMID- 29473244 TI - The increased trend of non-drinking in adolescence: The role of parental monitoring and attitudes toward offspring drinking. AB - INTRODUCTIONS AND AIMS: The proportion of adolescents who do not drink alcohol has increased during the last decade in many European countries, the USA and Australia. Few studies have addressed why this positive trend has occurred. The aim of the present study is to examine associations between parenting factors, peers' alcohol use and non-drinking among 15- to 16-year-old adolescents over time, from 2003 to 2015, and to evaluate potential gender differences. DESIGN AND METHODS: Data from the Swedish subsample of European School Survey Project on Alcohol and Other Drugs were used. Data were available for 2003, 2007, 2011 and 2015 in nation-based samples with responses from 11 531 adolescents in total. RESULTS: The proportion of non-drinkers increased from 23.2% in 2003 to 48.7% in 2015. For each year, indicators of especially restrictive attitudes toward offspring drinking were robustly associated with an increased probability of non drinking. However, neither indicators of parental monitoring nor parental attitudes toward offspring drinking were associated with the increase in the proportion of non-drinkers that occurred from 2003 to 2015. Two indicators of parental monitoring were more strongly associated with non-drinking among girls than among boys, while paternal restrictive attitudes toward offspring drinking were more strongly associated with non-drinking among boys than girls. DISCUSSION AND CONCLUSIONS: Parenting characteristics are important for adolescents who do not use alcohol, which has implications for prevention strategies. However, the increased trend of non-drinkers could not be attributed to parental factors. PMID- 29473245 TI - Does training people to administer take-home naloxone increase their knowledge? Evidence from Australian programs. AB - INTRODUCTION AND AIMS: Take-home naloxone (THN) programs have been operating in Australia since 2012 in a variety of settings. We examine whether THN programs were effective in increasing knowledge about opioid overdose and appropriate responses in program participants. DESIGN AND METHODS: Data were obtained from pre- and post-training questionnaires administered as part of the early evaluations of THN naloxone programs operated in Sydney (n = 67), Melbourne (n = 280), Perth (n = 153) and Canberra (n = 183). Pooled data from comparable items, analysed in the domains specified in previously-developed evaluation scales, were compared using repeated-measures analysis of variance and random effects logistic regression. Results pre- and post-training were compared as well as results across sites. RESULTS: High levels of knowledge about overdose risks and signs and appropriate actions to take were observed at baseline and this generally improved over time. No substantial differences were identified across cities. Knowledge also increased with participant age but the improvements over time were similar in each age group. There were small differences by participant gender with knowledge generally higher among females. DISCUSSION AND CONCLUSIONS: THN programs are effective in improving knowledge related to overdose response. Major improvements in knowledge were limited to overdose recognition and effect of naloxone suggesting that education may best be focused on overdose signs and the use of naloxone among populations accessed through these programs. A focus on younger people also appears warranted. Further work is needed to understand the impact of training and knowledge on actual behaviours around overdose events. PMID- 29473246 TI - Variant pathogenicity evaluation in the community-driven Inherited Neuropathy Variant Browser. AB - Charcot-Marie-Tooth disease (CMT) is an umbrella term for inherited neuropathies affecting an estimated one in 2,500 people. Over 120 CMT and related genes have been identified and clinical gene panels often contain more than 100 genes. Such a large genomic space will invariantly yield variants of uncertain clinical significance (VUS) in nearly any person tested. This rise in number of VUS creates major challenges for genetic counseling. Additionally, fewer individual variants in known genes are being published as the academic merit is decreasing, and most testing now happens in clinical laboratories, which typically do not correlate their variants with clinical phenotypes. For CMT, we aim to encourage and facilitate the global capture of variant data to gain a large collection of alleles in CMT genes, ideally in conjunction with phenotypic information. The Inherited Neuropathy Variant Browser provides user-friendly open access to currently reported variation in CMT genes. Geneticists, physicians, and genetic counselors can enter variants detected by clinical tests or in research studies in addition to genetic variation gathered from published literature, which are then submitted to ClinVar biannually. Active participation of the broader CMT community will provide an advance over existing resources for interpretation of CMT genetic variation. PMID- 29473247 TI - Double-blind placebo-controlled multicenter phase II trial to evaluate D methionine in preventing/reducing oral mucositis induced by radiation and chemotherapy for head and neck cancer. AB - BACKGROUND: The purpose of this study was to test if oral D-methionine (D-met) reduced mucositis during chemoradiotherapy. METHODS: We conducted a placebo controlled double-blind randomized phase II trial of D-met (100 mg/kg p.o. b.i.d.) testing the rate of severe (grades 3-4) mucositis. RESULTS: Sixty patients were randomized. Grade 2 + oral pain was higher with placebo (79% vs 45%; P = .0165), whereas grade 2 + body odor was greater with D-met (3% vs 41%; P = .0015). Mucositis was decreased with D-met by the physician (World Health Organization [WHO], P = .007; Radiation Therapy Oncology Group [RTOG], P = .009) and patient functional scales (RTOG, P = .0023). The primary end point of grades 3 to 4 mucositis on the composite scale demonstrated a decrease with D-met (48% vs 24%; P = .058), which was borderline in significance. A planned secondary analysis of a semiquantitative scoring system noted decreased oral ulceration (2.2 vs 1.5; P = .023) and erythema (1.6 vs 1.1; P = .048) with D-met. CONCLUSION: Although not meeting the primary end point, results of multiple assessments suggest that D-met decreased mucositis. PMID- 29473248 TI - Posttraumatic growth in head and neck cancer survivors: Is it possible and what are the correlates? AB - OBJECTIVES: Posttraumatic growth (PTG) is a possible positive consequence of a traumatic event, such as cancer. Head and neck cancer (HNC) may be particularly traumatic, given its adverse effects on functional, psychological, and social wellbeing. We investigated the extent of PTG, factors associated with PTG, and associations between PTG and health-related quality-of-life (HRQoL) in HNC survivors. METHODS: HNC survivors (ICD10 C00-C14, C32), identified from the population-based National Cancer Registry Ireland, completed a postal survey. PTG was assessed using the Posttraumatic Growth Inventory (PTG-I) and HRQoL with FACT G and FACT-H&N. Associations between socio-economic characteristics, social support, and clinical variables and PTG were examined using multivariable linear regression. Total HRQoL scores were compared in those with none-low PTG vs moderate-high PTG. RESULTS: A total of 583 survivors participated (response rate = 59%). The mean PTG score was 55.74 (95%CI 53.15-58.33); 60% had moderate-high PTG. Survivors scored highest in the PTG-I domain appreciation of life. In multivariable analysis, being female, being younger, having more social support, and having cancer-related financial stress were significantly associated with more PTG. HRQoL was significantly higher in those with moderate-high than no little PTG (P < .01). CONCLUSIONS: A notable proportion of HNC survivors report PTG but growth is, on average, lower than reported for other cancers. Nonetheless, higher PTG appears related to better HRQoL. Further research would be valuable to understand the pathways by which HNC may lead to PTG and inform development of strategies to support and encourage PTG in this survivor population.

PMID- 29473250 TI - Association between intrusive negative autobiographical memories and depression: A meta-analytic investigation. AB - The study investigated several associations between depression and intrusive negative autobiographical memories. A systematic literature search identified 23 eligible studies (N = 2,582), which provided 59 effect sizes. Separate meta analyses indicated that depression was moderately, positively associated with intrusive memory frequency, memory distress, maladaptive memory appraisals, memory avoidance, and memory rumination. Intrusive memory vividness was not significantly associated with depression. There were insufficient data to examine the relationship between depression and memory vantage perspective. Between-study heterogeneity was high for intrusive memory frequency and memory avoidance, and the percentage of females in studies significantly moderated the relationship between these variables and depression. An additional exploratory meta-analysis (3 studies; N = 257) indicated that intrusive memories were experienced more frequently by those with posttraumatic stress disorder than those with depression. Overall, the findings suggest that intrusive memories warrant clinical attention as they may contribute to the maintenance of depressive symptomatology. PMID- 29473251 TI - Modelling the influence of parental effects on gene-network evolution. AB - Understanding the importance of nongenetic heredity in the evolutionary process is a major topic in modern evolutionary biology. We modified a classical gene network model by allowing parental transmission of gene expression and studied its evolutionary properties through individual-based simulations. We identified ontogenetic time (i.e. the time gene networks have to stabilize before being submitted to natural selection) as a crucial factor in determining the evolutionary impact of this phenotypic inheritance. Indeed, fast-developing organisms display enhanced adaptation and greater robustness to mutations when evolving in presence of nongenetic inheritance (NGI). In contrast, in our model, long development reduces the influence of the inherited state of the gene network. NGI thus had a negligible effect on the evolution of gene networks when the speed at which transcription levels reach equilibrium is not constrained. Nevertheless, simulations show that intergenerational transmission of the gene network state negatively affects the evolution of robustness to environmental disturbances for either fast- or slow-developing organisms. Therefore, these results suggest that the evolutionary consequences of NGI might not be sought only in the way species respond to selection, but also on the evolution of emergent properties (such as environmental and genetic canalization) in complex genetic architectures. PMID- 29473252 TI - Transoral radical tonsillectomy and retropharyngeal lymph node dissection with a flexible next generation robotic surgical system. AB - BACKGROUND: The purpose of this study was to describe the use of a novel flexible, single-arm robot in performing a transoral radical tonsillectomy and retropharyngeal lymph node dissection. METHODS: A 63-year-old man with a T1N2bM0 (American Joint Committee on Cancer seventh edition classification) squamous cell carcinoma (SCC) of the left tonsil underwent a transoral robotic radical tonsillectomy and retropharyngeal lymph node dissection, followed by a left selective neck dissection of levels I to IV. RESULTS: The tonsillar tumor was removed completely with a negative margin that was followed by a dissection and removal of a retropharyngeal lymph node, completed with primary closure of the site. A left selective neck dissection was then performed. The patient was tolerating an oral diet on postoperative day 1 and had no robotic or surgically related complications at 30-day follow-up. CONCLUSION: It is feasible and safe to use this novel, flexible, single-arm robot in performing a transoral robotic radical tonsillectomy and retropharyngeal lymph node dissection.

PMID- 29473254 TI - Can the theory of planned behavior help explain attendance to follow-up care of childhood cancer survivors? AB - OBJECTIVE: Childhood cancer survivors are at high risk for late effects. Regular attendance to long-term follow-up care is recommended and helps monitoring survivors' health. Using the theory of planned behavior, we aimed to (1) investigate the predictors of the intention to attend follow-up care, and (2) examine the associations between perceived control and behavioral intention with actual follow-up care attendance in Swiss childhood cancer survivors. METHODS: We conducted a questionnaire survey in Swiss childhood cancer survivors (diagnosed with cancer aged <16 years between 1990 and 2005; >=5 years since diagnosis). We assessed theory of planned behavior-related predictors (attitude, subjective norm, perceived control), intention to attend follow-up care, and actual attendance. We applied structural equation modeling to investigate predictors of intention, and logistic regression models to study the association between intention and actual attendance. RESULTS: Of 299 responders (166 [55.5%] females), 145 (48.5%) reported attending follow-up care. We found that subjective norm, ie, survivors' perceived social pressure and support (coef = 0.90, P < 0.001), predicted the intention to attend follow-up; attitude and perceived control did not. Perceived control (OR = 1.58, 95%CI:1.04-2.41) and intention to attend follow-up (OR = 6.43, 95%CI:4.21-9.81) were positively associated with attendance. CONCLUSIONS: To increase attendance, an effort should be made to sensitize partners, friends, parents, and health care professionals on their important role in supporting survivors regarding follow-up care. Additionally, interventions promoting personal control over the follow-up attendance might further increase regular attendance. PMID- 29473255 TI - The Generalized Anxiety Disorder Screener (GAD-7) and the anxiety module of the Hospital and Depression Scale (HADS-A) as screening tools for generalized anxiety disorder among cancer patients. AB - OBJECTIVE: Anxiety in cancer patients may represent a normal psychological reaction. To detect patients with pathological levels, appropriate screeners with established cut-offs are needed. Given that previous research is sparse, we investigated the diagnostic accuracy of 2 frequently used screening tools in detecting generalized anxiety disorder (GAD). METHODS: We used data of a multicenter study including 2141 cancer patients. Diagnostic accuracy was investigated for the Generalized Anxiety Disorder Screener (GAD-7) and the anxiety module of the Hospital Anxiety and Depression Scale (HADS-A). GAD, assessed with the Composite International Diagnostic Interview for Oncology, served as a reference standard. Overall accuracy was measured with the area under the receiver operating characteristics curve (AUC). The AUC of the 2 screeners were statistically compared. We also calculated accuracy measures for selected cut-offs. RESULTS: Diagnostic accuracy could be interpreted as adequate for both screeners, with an identical AUC of .81 (95% CI: .79-.82). Consequently, the 2 screeners did not differ in their performance (P = .86). The best balance between sensitivity and specificity was found for cut-offs >=7 (GAD-7) and >=8 (HADS-A). The officially recommended thresholds for the GAD-7 (>= 10) and the HADS-A (>=11) showed low sensitivities of 55% and 48%, respectively. CONCLUSIONS: The GAD-7 and HADS-A showed AUC of adequate diagnostic accuracy and hence are applicable for GAD screening in cancer patients. Nevertheless, the choice of optimal cut-offs should be carefully evaluated. PMID- 29473256 TI - Editorial.

This represents the first reported case of a primary mixed adenoneuroendocrine carcinoma (MANEC) of the tongue arising within a congenital enteric cyst. METHODS: A 52-year-old man presented with a midline tongue mass that was connected to the mucosal surface with an epithelial-lined sinus tract. Morphological examination and immunohistochemical profiling of the neoplasm were performed. RESULTS: Histopathological evaluation showed a primary MANEC arising within a preexisting congenital enteric cyst, comprising both adenocarcinoma and neuroendocrine components. The adenocarcinoma had a colonic-type morphology and coexpressed CK7, CK20, and CDX2. Imaging and colonoscopy excluded a distant primary colorectal neoplasm. CONCLUSION: The association of primary MANEC of the tongue with a gastrointestinal heterotopic cyst supports an origin from entrapped endodermal elements as opposed to salivary duct origin. This case raises the awareness of a rare yet prognostically important complication of a gastrointestinal heterotopic cyst.

AB - BACKGROUND AND OBJECTIVES: Rising concerns regarding diversion and misuse of mono buprenorphine for treatment of pregnant women with opioid use disorders have sparked interest in the use of buprenorphine + naloxone to reduce misuse and diversion rates. Examined the relationship of prenatal buprenorphine + naloxone exposure to neonatal outcomes. METHODS: This is a retrospective chart review of 26 mother infant dyads in comprehensive medication-assisted treatment with buprenorphine + naloxone during pregnancy. RESULTS: All neonatal birth outcome parameters were within normal ranges, albeit on the lower side of normal for gestational age and birth weight. Only 19% of neonates required morphine pharmacology for NAS. CONCLUSIONS: Use of buprenorphine + naloxone shows relative safety in pregnancy. SCIENTIFIC SIGNIFICANCE: These findings can help better guide prescribing practices for pregnant patients at risk for misuse or diversion of buprenorphine. (Am J Addict 2018;27:92-96). PMID- 29473259 TI - Depression and anxiety symptoms during the transition to early adulthood for people with intellectual disabilities. AB - BACKGROUND: The transition to adulthood is a major developmental milestone; a time of self-discovery and increased independence. For young adults (YA) with intellectual disabilities (ID), however, this period is especially challenging. The increased incidence of mental health disorders in this population, such as depression and anxiety, make this transition even more difficult, increasing caregiver burden at a time when the young adult would traditionally be gaining independence. It is not clear, however, why YA with ID are more susceptible and what factors may predict mental health symptoms. METHOD: Potential risk and protective factors (demographic variables, coping styles, sense of hopelessness, unmet achievement of adulthood milestones, self-reflection and insight) of anxiety and depression symptoms were assessed in 55 YA with ID and a sample of age-matched controls. RESULTS: Insight was the strongest predictor of anxiety (with gender in the controls) for YA with and without ID, with increased insight predicting fewer anxiety symptoms. However, YA with ID had significantly less insight than their aged-matched counterparts and significantly higher levels of anxiety. They were also less likely to have achieved traditional adulthood milestones. Maladaptive coping was the strongest predictor of depression for YA with ID. In comparison, both maladaptive coping and insight predicted depression in controls. More maladaptive coping predicted increased depressive symptoms in both populations, whilst increased insight predicted fewer depressive symptoms in controls. CONCLUSIONS: Insight and maladaptive coping are potential targets in the treatment of anxiety and depression among YA with ID. Longitudinal intervention studies exploring the efficacy of such targeted programmes in reducing mental health symptoms and improving the transition to adulthood for these young people are recommended.

AB - The aim of this article is to elucidate how nurses are positioned in Canadian news stories regarding their salaries. While the image of nursing in mass media has been widely studied, few studies explore how nurses are constructed in news stories. Drawing on ideas from institutional ethnography together with discourse analysis, this discussion highlights public textual discourses about nurses' salaries in Canadian news stories. The media discourse was found to distort the issues by focusing attention on nurses. Recognizing how these textual distortions mediate and construct messages is important in understanding how nurses and their work are constructed in the media. This discussion seeks to inform readers about how nurses are situated within commonly circulated discourses in the media. It also seeks to contribute to the literature about the nurse's image and how nurses and their work are portrayed in the public realm. It concludes by recommending increased awareness about how nurses are talked about in mass communication and the need to disrupt these messages and their underlying assumptions. PMID- 29473261 TI - Spanish version of the modified Advanced Practice Role Delineation tool, adaptation and psychometric properties. AB - BACKGROUND: Role clarity is vital to avoid confusion and role ambiguity within nursing. There is a need for valid, reliable tools that can delineate the profile of advanced nursing practice to measure the extent of advanced practices in Spain. AIM: The main purpose of this study was to translate, cross-culturally adapt, and psychometrically test the Spanish version of the modified Advanced Practice Role Delineation tool. DESIGN: The study was designed to follow symmetrical translation and cognitive debriefing to determine conceptual equivalence. A cross-sectional survey was conducted to examine content validity and psychometric tests. METHODS: Data were collected over 6 months in 2015 and 2016. The study had a purposive sample of specialist nurses and nurses with an extended practice profile beyond that of a general nurse. RESULTS: The study achieved conceptual, semantic, and content equivalence of the items. The results provided support for the instrument's validity and reliability in advanced practice nursing in a tertiary and community hospital. The tool showed internal consistency, with a Cronbach's alpha coefficient of 0.86 and stability over time. CONCLUSION: The findings should influence future nursing practice, research, and leadership while allowing assessment of Spanish advanced practice roles in an international context. PMID- 29473262 TI - Local functional connectivity suggests functional immaturity in children with attention-deficit/hyperactivity disorder. AB - Previous studies have associated Attention-Deficit/Hyperactivity Disorder (ADHD) with a maturational lag of brain functional networks. Functional connectivity of the human brain changes from primarily local to more distant connectivity patterns during typical development. Under the maturational lag hypothesis, we expect children with ADHD to exhibit increased local connectivity and decreased distant connectivity compared with neurotypically developing (ND) children. We applied a graph-theory method to compute local and distant connectivity levels and cross-sectionally compared them in a sample of 120 children with ADHD and 120 age-matched ND children (age range = 7-17 years). In addition, we measured if potential group differences in local and distant connectivity were stable across the age range considered. Finally, we assessed the clinical relevance of observed group differences by correlating the connectivity levels and ADHD symptoms severity separately for each group. Children with ADHD exhibited more local connectivity than age-matched ND children in multiple brain regions, mainly overlapping with default mode, fronto-parietal and ventral attentional functional networks (p < .05- threshold free-cluster enhancement-family-wise error). We detected an atypical developmental pattern of local connectivity in somatomotor regions, that is, decreases with age in ND children, and increases with age in children with ADHD. Furthermore, local connectivity within somatomotor areas correlated positively with clinical severity of ADHD symptoms, both in ADHD and ND children. Results suggest an immature functional state of multiple brain networks in children with ADHD. Whereas the ADHD diagnosis is associated with the integrity of the system comprising the fronto-parietal, default mode and ventral attentional networks, the severity of clinical symptoms is related to atypical functional connectivity within somatomotor areas. Additionally, our findings are in line with the view of ADHD as a disorder of deviated maturational trajectories, mainly affecting somatomotor areas, rather than delays that normalize with age. PMID- 29473263 TI - Spectroscopic and Computational Characterization of Diethylenetriaminepentaacetic Acid/Transplutonium Chelates: Evidencing Heterogeneity in the Heavy Actinide(III) Series. AB - The chemistry of trivalent transplutonium ions (Am3+ , Cm3+ , Bk3+ , Cf3+ , Es3+ ...) is usually perceived as monotonic and paralleling that of the trivalent lanthanide series. Herein, we present the first extended X-ray absorption fine structure (EXAFS) study performed on a series of aqueous heavy actinide chelates, extending past Cm. The results obtained on diethylenetriaminepentaacetic acid (DTPA) complexes of trivalent Am, Cm, Bk, and Cf show a break to much shorter metal-oxygen nearest-neighbor bond lengths in the case of Cf3+ . Corroborating those results, density functional theory calculations, extended to Es3+ , suggest that the shorter Cf-O and Es-O bonds could arise from the departure of the coordinated water molecule and contraction of the ligand around the metal relative to the other [MIII DTPA(H2 O)]2- (M=Am, Cm, Bk) complexes. Taken together, these experimental and theoretical results demonstrate inhomogeneity within the trivalent transplutonium series that has been insinuated and debated in recent years, and that may also be leveraged for future nuclear waste reprocessing technologies. PMID- 29473264 TI - Cyanine Photocages Enable Spatial Control of Inducible Cre-Mediated Recombination. AB - Optical control over protein expression could provide a means to interrogate a range of biological processes. One approach has employed caged ligands of the estrogen receptor (ER) in combination with broadly used ligand-dependent Cre recombinase proteins. Existing approaches use UV or blue wavelengths, which hinders their application in tissue settings. Additionally, issues of payload diffusion can impede fine spatial control over the recombination process. Here, we detail the chemical optimization of a near-infrared (NIR) light-activated variant of the ER antagonist cyclofen. These studies resulted in modification of both the caging group and payload with lipophilic n-butyl esters. The appendage of esters to the cyanine cage improved cellular uptake and retention. The installation of a 4-piperidyl ester enabled high spatial resolution of the light initiated Cre-mediated recombination event. These studies described chemical modifications with potential general utility for improving spatial control of intracellular caging strategies. Additionally, these efforts will enable future applications to use these molecules in complex physiological settings. PMID- 29473265 TI - Cytotoxic T lymphocyte response to peptide vaccination predicts survival in stage III colorectal cancer. AB - We previously reported a phase I clinical trial of a peptide vaccine ring finger protein 43 (RNF43) and 34-kDa translocase of the outer mitochondrial membrane (TOMM34) combined with uracil-tegafur (UFT)/LV for patients with metastatic colorectal cancer (CRC), and demonstrated the safety and immunological responsiveness of this combination therapy. In this study, we evaluated vaccination-induced immune responses to clarify the survival benefit of the combination therapy as adjuvant treatment. We enrolled 44 patients initially in an HLA-masked fashion. After the disclosure of HLA, 28 patients were in the HLA A*2402-matched and 16 were in the unmatched group. In the HLA-matched group, 14 patients had positive CTL responses specific for the RNF43 and/or TOMM34 peptides after 2 cycles of treatment and 9 had negative responses; in the HLA-unmatched group, 10 CTL responses were positive and 2 negative. In the HLA-matched group, 3 year relapse-free survival (RFS) was significantly better in the positive CTL subgroup than in the negative-response subgroup. Patients with negative vaccination-induced CTL responses showed a significant trend towards shorter RFS than those with positive responses. Moreover, in the HLA-unmatched group, the positive CTL response subgroup showed an equally good 3-year RFS as in the HLA matched group. In conclusion, vaccination-induced CTL response to peptide vaccination could predict survival in the adjuvant setting for stage III CRC.

AB - beta-Functionalized ketones are a highly important and valuable class of compounds that have gained increasing attention from organic chemists due to their intensive uses as versatile synthetic intermediates and building blocks in complex molecule assembly and natural product synthesis. Accordingly, there is continuing interest in the development of new approaches for the synthesis of beta-functionalized ketones. In recent years, radical-mediated 1,2-rearrangement reactions of allylic alcohols, which proceed through cationic (semipinacol) rearrangements or radical (neophyl) rearrangements, have presented an attractive and powerful strategy to access various diversely beta-functionalized ketones. Interestingly, this strategy allows for the direct installation of a variety of valuable functional groups at the beta-position of cyclic and acyclic ketones by employing different radical precursors. However, a review focusing on the preparation of beta-functionalized ketones by radical-mediated 1,2-rearrangement reactions of allylic alcohols has not been summarized to date. This Minireview highlights recent progress made in this highly active and interesting research area, and the corresponding mechanisms will also be discussed. PMID- 29473266 TI - Anti-human SIRPalpha antibody is a new tool for cancer immunotherapy. AB - Interaction of signal regulatory protein alpha (SIRPalpha) expressed on the surface of macrophages with its ligand CD47 expressed on target cells negatively regulates phagocytosis of the latter cells by the former. We recently showed that blocking Abs to mouse SIRPalpha enhanced both the Ab-dependent cellular phagocytosis (ADCP) activity of mouse macrophages for Burkitt's lymphoma Raji cells opsonized with an Ab to CD20 (rituximab) in vitro as well as the inhibitory effect of rituximab on the growth of tumors formed by Raji cells in nonobese diabetic (NOD)/SCID mice. However, the effects of blocking Abs to human SIRPalpha in preclinical cancer models have remained unclear given that such Abs have failed to interact with endogenous SIRPalpha expressed on macrophages of immunodeficient mice. With the use of Rag2-/- gammac-/- mice harboring a transgene for human SIRPalpha under the control of human regulatory elements (hSIRPalpha-DKO mice), we here show that a blocking Ab to human SIRPalpha significantly enhanced the ADCP activity of macrophages derived from these mice for human cancer cells. The anti-human SIRPalpha Ab also markedly enhanced the inhibitory effect of rituximab on the growth of tumors formed by Raji cells in hSIRPalpha-DKO mice. Our results thus suggest that the combination of Abs to human SIRPalpha with therapeutic Abs specific for tumor antigens warrants further investigation for potential application to cancer immunotherapy. In addition, humanized mice, such as hSIRPalpha-DKO mice, should prove useful for validation of the antitumor effects of checkpoint inhibitors before testing in clinical trials. PMID- 29473268 TI - Metal-Free Dehydrogenation of N-Heterocycles by Ternary h-BCN Nanosheets with Visible Light. AB - An efficient metal-free catalytic system has been developed based on hexagonal boron carbon nitride (h-BCN) nanosheets for the dehydrogenation of N-heterocycles with visible light; hydrogen gas is released in the process, and thus no proton acceptor is needed. This acceptorless dehydrogenation of hydroquinolines, hydroisoquinolines, and indolines to the corresponding aromatic N-heterocycles occurred in excellent yield under visible-light irradiation at ambient temperature. With h-BCN as the photocatalyst and water as the solvent, this environmentally benign protocol shows broad substitution tolerance and high efficiency. PMID- 29473269 TI - Maternal viral load and hepatitis B virus mother-to-child transmission risk: A systematic review and meta-analysis. AB - AIM: The aim of this study was to assess the relationship between maternal viral load and mother-to-child transmission (MTCT) risk in hepatitis B envelope antigen (HBeAg)-positive mothers. METHODS: PubMed and Web of Science were systematically searched. We compared MTCT incidence between maternal hepatitis B virus (HBV)-DNA positive and HBV-DNA-negative groups. We also examined the dose-response effect of this relationship. RESULTS: Twenty-one studies with 10 142 mother-child pairs were included in the studies. The mean MTCT incidence was 13.1% in the maternal HBV-DNA-positive group, compared with 4.2% in the negative group. The summary MTCT odds ratio of maternal HBV-DNA positive compared with negative was 9.895 (95% confidence interval [CI], 5.333 to 18.359; Z = 7.27, P < 0.00001) by random effects model. In maternal HBV-DNA <6 log10 copies/mL, 6-8 log10 copies/mL, and >8 log10 copies/mL level stratifications, the pooled MTCT incidences were 2.754% (95% CI, 1.198-4.310%; Z = 3.47, P = 0.001), 9.932% (95% CI, 6.349-13.516%; Z = 5.43, P < 0.00001), and 14.445% (95% CI, 8.317-20.572%; Z = 4.62, P < 0.00001), respectively. A significant linear dose-response association was found between maternal viral load and MTCT risk, with the points estimate of increased MTCT risk 2.705 (95% CI, 1.808-4.047) at 6 log10 copies/mL compared with reference (3 log10 copies/mL), and 7.316 (95% CI, 3.268-16.378) at 9 log10 copies/mL. A significant non-linear dose-response association was also found between maternal viral load and HBV MTCT risk (model chi2 = 23.43, P < 0.00001). CONCLUSION: Our meta-analysis indicated that maternal viral load was an important risk factor for MTCT in HBeAg-positive mothers, and maternal viral load was dose-dependent with HBV MTCT incidence. PMID- 29473270 TI - Fluoride-Catalyzed Deblocking: A Route to Polymeric Urethanes. AB - We report a fluoride-catalyzed deblocking of urethanes as "blocked" isocyanates. Organic and inorganic sources of fluoride ion proved effective for deblocking urethanes and for converting polyurethanes to small molecules. Distinct from conventional deblocking chemistry involving organometallic compounds and high temperatures, the method we describe is metal-free and operates at or slightly above room temperature. The use of fluorescent blocking agents enabled visual and spectroscopic monitoring of blocking/deblocking reactions, and the selected conditions proved applicable to urethanes containing a variety of blocking groups. The method additionally enabled a one pot deblocking and polymerization with alpha,omega-diols. Overall, this deblocking/polymerization strategy offers a convenient and efficient solution to problems that have limited the breadth of applications of polyurethane chemistry. PMID- 29473271 TI - Neutropenia in pediatric heart transplant recipients. AB - Neutropenia has been reported in pediatric heart transplant recipients, but its association with infectious morbidity and mortality is unknown. We sought to determine neutropenia's prevalence and impact on infection, rejection, and survival. A retrospective analysis of pediatric heart transplant recipients from March 2005 to August 2015 was performed. Demographics, medications, infection, and rejection data were collected. Of 142 pediatric heart transplant recipients, 77 (54.2%) developed neutropenia within 4.7 months [3.3-12.1 months] of transplant. In all patients, the adjusted 5-year cumulative incidence of neutropenia was 30.2%. Fifty-one patients (66.2%) had recurrent neutropenia. Six of 14 tested had positive antineutrophil antibodies. Medications associated with neutropenia were decreased in 15 (19.5%) and discontinued in 42 (54.4%) patients with no change in 1-year rejection rates compared to published data. Fifteen patients developed infection within 30 days of neutropenia and two from 30 days to 1 year, with an infection rate similar to the non-neutropenic group. There was no significant difference in survival, ANC, rate of rejection or PTLD in neutropenic patients with and without infection at median follow-up (5.5 years). Neutropenia is common in pediatric heart transplant recipients. Neutropenia had <20% risk of associated infection, similar to non-neutropenic patients. Infection in neutropenic patients did not increase mortality. PMID- 29473272 TI - Li2 B12 and Li3 B12 : Prediction of the Smallest Tubular and Cage-like Boron Structures. AB - An intriguing structural transition from the quasi-planar form of B12 cluster upon the interaction with lithium atoms is reported. High-level computations show that the lowest energy structures of LiB12 , Li2 B12 , and Li3 B12 have quasi planar (Cs ), tubular (D6d ), and cage-like (Cs ) geometries, respectively. The energetic cost of distorting the B12 quasi-planar fragment is overcompensated by an enhanced electrostatic interaction between the Li cations and the tubular or cage-like B12 fragments, which is the main reason of such drastic structural changes, resulting in the smallest tubular (Li2 B12 ) and cage-like (Li3 B12 ) boron structures reported to date. PMID- 29473273 TI - Systematic review of strategies to increase access to health services among children over five in low- and middle-income countries. AB - BACKGROUND: The populations of many low- and middle-income countries (LMIC) are young. Despite progress made towards achieving Universal Health Coverage and remarkable health gains, evidence suggests that many children in LMIC are still not accessing needed healthcare services. Delayed or lack of access to health services can lead to a worsening of health and can in turn negatively impact a child's ability to attend school, and future employment opportunities. METHODS: We conducted a systematic review to assess the effectiveness of interventions aimed at increasing access to health services for children over 5 years in LMIC settings. Four electronic databases were searched in March 2017. Studies were included if they evaluated interventions that aimed to increase: healthcare utilisation, immunisation uptake and compliance with medication/referral. Randomised controlled trials and non-randomised study designs were included in the review. Data extraction included study characteristics, intervention type and measures of access to health services for children above 5 years of age. Study outcomes were classified as positive, negative, mixed or null in terms of their impact on access outcomes. RESULTS: Ten studies met the criteria for inclusion in the review. Interventions were evaluated in Nicaragua (1), Brazil (1), Turkey (1), India (1), China (1), Uganda (1), Ghana (1), Nigeria (1), South Africa (1) and Swaziland (1). Intervention types included education (2), incentives (1), outreach (1), SMS/phone call reminders (2) and multicomponent interventions (4). All evaluations reported positive findings on measured health access outcomes; however, the quality and strength of evidence were mixed. CONCLUSION: This review provides evidence of the range of interventions that were used to increase healthcare access for children above 5 years old in LMIC. Nevertheless, further research is needed to examine each of the identified intervention types and the influence of contextual factors, with robust study designs. There is also a need to assess the cost-effectiveness of the interventions to inform decision-makers on which are suitable for scale-up in their particular contexts. PMID- 29473274 TI - Chaotropic Monovalent Anion-Induced Rectification Inversion at Nanopipettes Modified by Polyimidazolium Brushes. AB - A nonintuitive observation of monovalent anion-induced ion current rectification inversion at polyimidazolium brush (PimB)-modified nanopipettes is presented. The rectification inversion degree is strongly dependent on the concentration and species of monovalent anions. For chaotropic anions (for example, ClO4- ), the rectification inversion is easily observed at a low concentration (5 mm), while there is no rectification inversion observed for kosmotropic anions (Cl- ) even at a high concentration (1 m). Moreover, at the specific concentration (for example, 10 mm), the variation of rectification ratio on the type of anions is ranged by Hofmeister series (Cl- >=NO3- >BF4- >ClO4- >PF6- >Tf2 N- ). Estimation of the electrokinetic charge density (sigmaek ) demonstrates that rectification inversion originates from the charge inversion owing to the over-adsorption of chaotropic monovalent anion. To qualitatively understand this phenomenon, a concentration-dependent adsorption mechanism is proposed.

AB - We present an expedient and economical route to a new spiroketal-based C2 symmetric chiral scaffold, termed SPIROL. Based on this spirocyclic scaffold, several chiral ligands were generated. These ligands were successfully employed in an array of stereoselective transformations, including in iridium-catalyzed hydroarylations (up to 95 % ee), palladium-catalyzed allylic alkylations (up to 97 % ee), intermolecular palladium-catalyzed Heck couplings (up to 94 % ee), and rhodium-catalyzed dehydroalanine hydrogenation (up to 93 % ee).

PMID- 29473277 TI - Formation of p62-positive inclusion body is associated with macrophage polarization in non-alcoholic fatty liver disease. AB - AIM: Hepatic inclusion composed of autophagy-specific substrate p62 is one of the histological features of non-alcoholic fatty liver disease (NAFLD) and can be a precursor to hepatic carcinogenesis. The expression of p62 was enhanced by not only autophagic dysfunction but also oxidative stress and inflammation. M1/M2 phenotypic balance of macrophages plays a pivotal role in the progression of NAFLD. We evaluated the correlation between macrophage polarization and the formation of p62 aggregation in NAFLD. METHODS: Liver biopsy specimens from NAFLD patients were analyzed by immunohistochemical staining for M1 macrophage marker CD11c, M2 macrophage marker CD163, and p62/SQSTM1 (p62). The histological severity of NAFLD is assessed by a NAFLD activity score (NAS). The number of autophagic vesicles in hepatocytes was visualized and counted by using transmission electron microscopy. RESULTS: The aggregation of p62 was undetectable in control, whereas hepatocytes with p62 aggregation were observed in approximately 88% of NAFLD specimens. The number of hepatocytes with p62 aggregation was positively correlated with the number of autophagic vesicles, serum alanine aminotransferase, NAS, fibrosis, and the number of CD11c-positive cells, but not CD163-positive cells. Assembly of CD11c-positive cells was observed around hepatocytes with p62 aggregation. The ratio of CD11c/CD163 positive macrophages was significantly associated with the formation of p62 aggregation. CONCLUSIONS: These findings indicate that chronic inflammation by M1 polarization of macrophages contributes to the disease progression from simple steatosis to non-alcoholic steatohepatitis in concert with autophagic dysfunction. PMID- 29473278 TI - Both widespread PEP-CTERM proteins and exopolysaccharides are required for floc formation of Zoogloea resiniphila and other activated sludge bacteria. AB - Bacterial floc formation plays a central role in the activated sludge (AS) process, which has been widely utilized for sewage and wastewater treatment. The formation of AS flocs has long been known to require exopolysaccharide biosynthesis. This study demonstrates an additional requirement for a PEP-CTERM protein in Zoogloea resiniphila, a dominant AS bacterium harboring a large exopolysaccharide biosynthesis gene cluster. Two members of a wide-spread family of high copy number-per-genome PEP-CTERM genes, transcriptionally regulated by the RpoN sigma factor and accessory PrsK-PrsR two-component system and at least one of these, pepA, must be expressed for Zoogloea to build the floc structures that allow gravitational sludge settling and recycling. Without PrsK or PrsR, Zoogloea cells were planktonic rather than flocculated and secreted exopolysaccharides were released into the growth broth in soluble form. Overexpression of PepA could circumvent the requirement of rpoN, prsK and prsR for the floc-forming phenotype by fixing the exopolysaccharides to bacterial cells. However, overexpression of PepA, which underwent post-translational modifications, could not rescue the long-rod morphology of the rpoN mutant. Consistently, PEP-CTERM genes and exopolysaccharide biosynthesis gene cluster are present in the genome of the floc-forming Nitrospira comammox and Mitsuaria strain as well as many other AS bacteria. PMID- 29473279 TI - Autism spectrum disorder and genetic testing: Parental perceptions and decision making. AB - PURPOSE: Advances in genomic technology and research have led to genetic testing being recognized as an essential component of the etiological workup for children with autism spectrum disorder (ASD). Chromosomal microarray analysis (CMA) is a first-tier diagnostic test for patients with ASD, as recommended by the American College of Medical Genetics and other professional societies. An accurate underlying medical diagnosis for ASD has many potential benefits, including appropriate medical management, detailed therapeutic recommendations, and accurate recurrence risk. Genetic testing is relatively complicated, expensive, and, currently, in the majority of the cases, does not provide any organic improvement in the management of symptoms. DESIGN AND METHODS: We conducted semistructured interviews with 20 parents to explore the decision-making process of genetic testing from the perspectives and experiences of parents of children with ASD. Data were analyzed using qualitative content analysis. RESULTS: Parents had limited knowledge of genetic testing for ASD prior to a genetics clinic visit. The majority of the participants thought genetic testing would be beneficial for their child, their reproductive choices, and potential future generations. PRACTICE IMPLICATIONS: Various stakeholders (geneticists, primary care providers, nurses, and families) would benefit from future establishment of educational strategies to inform parental decision-making regarding genetic testing for children with ASD. PMID- 29473280 TI - Effect of platelets-rich plasma on scalp hair diameter. AB - OBJECTIVES: To measure the effects of platelet-rich plasma (PRP) on hair diameter in Pakistani population. MATERIALS AND METHODS: The study was conducted in a private setup in the adult patients undergoing PRP treatment. Baseline platelets count was noted for each patient. PRP was prepared using a commercial kit. Three PRP injections were administered in the scalp at 0, 1, and 3 months of interval. The hair caliber was measured in the mid-scalp area using a separate stencil for each patient. The diameter of 10 hair (1 cm sq) was measured randomly using the caliper (2 hair on each side of the square and 4 in the center). After 6 months of 3rd injection, the hair caliber was measured and the results were analyzed statistically using Mann-Whitney's test. RESULTS: Seven men and 3 women were included in the study. The mean age of the patients was 24.2 years (26.3 years in males and 19.3 in females). The average platelets count was found to be 283,580/MUL. The mean hair caliber was 37.3 MUm (39.1 MUm in men and 33.0 MUm in women). At the end of the study, the mean hair caliber was found to be 52.3 MUm (P < .01). The mean hair caliber was 53.9 MUm in men and 48.7 MUm in women (P < .01). The increase in the hair caliber was noted to be 27.5% more in men and 31.3% more in women (P < .01). CONCLUSION: The PRP injections can increase the hair diameter. PMID- 29473281 TI - Postpartum venous thromboembolism prophylaxis: harm versus benefit. PMID- 29473282 TI - Antioxidant action and protective and reparative effects of lentinan on oxidative damage in HaCaT cells. AB - BACKGROUND: Lentinus edodes is one of the largest edible fungi. Lentinan, extracted from its fruiting body has clinically significant anticancer, antibacterial, antiviral, and anticoagulant effects; however, its preventive effects on skin oxidative damage are unclear. AIMS: We aimed to evaluate the in vitro antioxidation capability of lentinan and its protective and reparative effects on a model of cell oxidative damage. METHODS: We evaluated the in vitro antioxidant potential of lentinan by assessing its free-radical quenching ability using DPPH and ABTS and superoxide anions. Using the HaCaT cell line as the experimental system, we tested the protective and reparative effects of lentinan on a model of H2 O2 -induced cellular oxidative damage through assessment of cell survival rate, malondialdehyde (MDA) content, and superoxide dismutase (SOD) activity. RESULTS: Lentinan displayed high antioxidant potential: DDPH and ABTS quenching rates were above 60%; superoxide anions, approximately 18%. Furthermore, lentinan could dose-dependently prevent the reduction of activity in HaCaT cells by H2 O2 , reduce MDA formation, and increase SOD activity. Moreover, lentinan showed not only a protective effect against oxidative damage but also reparative effects to a certain extent, in HaCaT cells. CONCLUSIONS: Our findings demonstrated the ability of lentinan to enhance cellular tolerance to oxidative damage, stress resistance, and to have protective and reparative effects on damaged cells. Therefore, with L. edodes as a source for antiaging substances, cosmetics with homology to foods have great potential clinical applications. PMID- 29473283 TI - The purple non-sulfur bacterium Rhodopseudomonas palustris produces novel petrobactin-related siderophores under aerobic and anaerobic conditions. AB - Many bacteria produce siderophores to bind and take up Fe(III), an essential trace metal with extremely low solubility in oxygenated environments at circumneutral pH. The purple non-sulfur bacterium Rhodopseudomonas palustris str. CGA009 is a metabolically versatile model organism with high iron requirements that is able to grow under aerobic and anaerobic conditions. Siderophore biosynthesis has been predicted by genomic analysis, however, siderophore structures were not identified. Here, we elucidate the structure of two novel siderophores from R. palustris: rhodopetrobactin A and B. Rhodopetrobactins are structural analogues of the known siderophore petrobactin in which the Fe chelating moieties are conserved, including two 3,4-dihydroxybenzoate and a citrate substructure. In the place of two spermidine linker groups in petrobactin, rhodopetrobactins contain two 4,4'-diaminodibutylamine groups of which one or both are acetylated at the central amine. We analyse siderophore production under different growth modes and show that rhodopetrobactins are produced in response to Fe limitation under aerobic as well as under anaerobic conditions. Evaluation of the chemical characteristics of rhodopetrobactins indicates that they are well suited to support Fe acquisition under variable oxygen and light conditions.

AB - Although the confirmation of inflammatory changes within tissues at the onset of various diseases is critical for the early detection of disease and selection of appropriate treatment, most therapies are based on complex and time-consuming diagnostic procedures. Raman spectroscopy has the ability to provide non invasive, real-time, chemical bonding analysis through the inelastic scattering of photons. In this study, we evaluate the feasibility of Raman spectroscopy as a new, easy, fast, and accurate diagnostic method to support diagnostic decisions. The molecular changes in carrageenan-induced acute inflammation rat tissues were assessed by Raman spectroscopy. Volumes of 0 (control), 100, 150, and 200 uL of 1% carrageenan were administered to rat hind paws to control the degree of inflammation. The prominent peaks at [1,062, 1,131] cm-1 and [2,847, 2,881] cm-1 were selected as characteristic measurements corresponding to the C-C stretching vibrational modes and the symmetric and asymmetric C-H (CH2 ) stretching vibrational modes, respectively. Principal component analysis of the inflammatory Raman spectra enabled graphical representation of the degree of inflammation through principal component loading profiles of inflammatory tissues on a two dimensional plot. Therefore, Raman spectroscopy with multivariate statistical analysis represents a promising method for detecting biomolecular responses based on different types of inflammatory tissues.

AB - Morphological evolution from a unicellular to multicellular state provides greater opportunities for organisms to attain larger and more complex living forms. As the most common freshwater cyanobacterial genus, Microcystis is a unicellular microorganism, with high phenotypic plasticity, which forms colonies and blooms in lakes and reservoirs worldwide. We conducted a systematic review of field studies from the 1990s to 2017 where Microcystis was dominant. Microcystis was detected as the dominant genus in waterbodies from temperate to subtropical and tropical zones. Unicellular Microcystis spp. can be induced to form colonies by adjusting biotic and abiotic factors in laboratory. Colony formation by cell division has been induced by zooplankton filtrate, high Pb2+ concentration, the presence of another cyanobacterium (Cylindrospermopsis raciborskii), heterotrophic bacteria, and by low temperature and light intensity. Colony formation by cell adhesion can be induced by zooplankton grazing, high Ca2+ concentration, and microcystins. We hypothesise that single cells of all Microcystis morphospecies initially form colonies with a similar morphology to those found in the early spring. These colonies gradually change their morphology to that of M. ichthyoblabe, M. wesenbergii and M. aeruginosa with changing environmental conditions. Colony formation provides Microcystis with many ecological advantages, including adaption to varying light, sustained growth under poor nutrient supply, protection from chemical stressors and protection from grazing. These benefits represent passive tactics responding to environmental stress. Microcystis colonies form at the cost of decreased specific growth rates compared with a unicellular habit. Large colony size allows Microcystis to attain rapid floating velocities (maximum recorded for a single colony, ~ 10.08 m h-1 ) that enable them to develop and maintain a large biomass near the surface of eutrophic lakes, where they may shade and inhibit the growth of less-buoyant species in deeper layers. Over time, accompanying species may fail to maintain viable populations, allowing Microcystis to dominate. Microcystis blooms can be controlled by artificial mixing. Microcystis colonies and non-buoyant phytoplankton will be exposed to identical light conditions if they are evenly distributed over the water column. In that case, green algae and diatoms, which generally have a higher growth rate than Microcystis, will be more successful. Under such mixing conditions, other phytoplankton taxa could recover and the dominance of Microcystis would be reduced. This review advances our understanding of the factors and mechanisms affecting Microcystis colony formation and size in the field and laboratory through synthesis of current knowledge. The main transition pathways of morphological changes in Microcystis provide an example of the phenotypic plasticity of organisms during morphological evolution from a unicellular to multicellular state. We emphasise that the mechanisms and factors influencing competition among various close morphospecies are sometimes paradoxical because these morphospecies are potentially a single species. Further work is required to clarify the colony-forming process in different Microcystis morphospecies and the seasonal variation in this process. This will allow researchers to grow laboratory cultures that more closely reflect field morphologies and to optimise artificial mixing to manage blooms more effectively. PMID- 29473287 TI - A laboratory exercise for detecting microbial contaminants. AB - The development and evaluation of a 6-hours laboratory class, based on capillary electrophoresis (CE) and the detection of microbial contaminants, is described. It can be easily scaled up or down, to suit class sizes up to 188 and completed in a shorter time scale. CE uses narrow-bore fused-silica capillaries to separate a complex array of large and small molecules. A laboratory exercise has been devised to illustrate how CE-based genetic analysis system processes DNA fragment analysis to detect three microbial contaminants. The protocol is relatively inexpensive and uses standard molecular biology reagents and equipment. (c) 2018 by The International Union of Biochemistry and Molecular Biology, 46(3):279-284, 2018. PMID- 29473288 TI - Increasing N deposition impacts neither diversity nor functions of deadwood inhabiting fungal communities, but adaptation and functional redundancy ensure ecosystem function. AB - Nitrogen deposition can strongly affect biodiversity, but its specific effects on terrestrial microbial communities and their roles for ecosystem functions and processes are still unclear. Here, we investigated the impacts of N deposition on wood-inhabiting fungi (WIF) and their related ecological functions and processes in a highly N-limited deadwood habitat. Based on high-throughput sequencing, enzymatic activity assay and measurements of wood decomposition rates, we show that N addition has no significant effect on the overall WIF community composition or on related ecosystem functions and processes in this habitat. Nevertheless, we detected several switches in presence/absence (gain/loss) of wood-inhabiting fungal OTUs due to the effect of N addition. The responses of WIF differed from previous studies carried out with fungi living in soil and leaf litter, which represent less N-limited fungal habitats. Our results suggest that adaptation at different levels of organization and functional redundancy may explain this buffered response and the resistant microbial-mediated ecosystem function and processes against N deposition in highly N-limited habitats.

PMID- 29473291 TI - Bayesian approach for assessing noninferiority in a three-arm trial with binary endpoint. AB - With the recent advancement in many therapeutic areas, quest for better and enhanced treatment options is ever increasing. While the "efficacy" metric plays the most important role in this development, emphasis on other important clinical factors such as less intensive side effects, lower toxicity, ease of delivery, and other less debilitating factors may result in the selection of treatment options, which may not beat current established treatment option in terms efficacy, yet prove to be desirable for subgroups of patients. The resultant clinical trial by means of which one establishes such slightly less efficacious treatment is known as noninferiority (NI) trial. Noninferiority trials often involve an active established comparator arm, along with a placebo and an experimental treatment arm, resulting into a 3-arm trial. Most of the past developments in a 3-arm NI trial consider defining a prespecified fraction of unknown effect size of reference drug, i.e., without directly specifying a fixed NI margin. However, in some recent developments, more direct approach is being considered with prespecified fixed margin, albeit in the frequentist setup. In this article, we consider Bayesian implementation of such trial when primary outcome of interest is binary. Bayesian paradigm is important, as it provides a path to integrate historical trials and current trial information via sequential learning. We use several approximation-based and 2 exact fully Bayesian methods to evaluate the feasibility of the proposed approach. Finally, a clinical trial example is reanalyzed to demonstrate the benefit of the proposed approach. PMID- 29473290 TI - Estimating gestational age at birth from fundal height and additional anthropometrics: a prospective cohort study. AB - OBJECTIVE: Accurate assessment of gestational age (GA) is critical to paediatric care, but is limited in developing countries without access to ultrasound. Our objectives were to assess the accuracy of prediction of GA at birth and preterm birth classification using routinely collected anthropometry measures. DESIGN: Prospective cohort study. SETTING: United States. POPULATION OR SAMPLE: A total of 2334 non-obese and 468 obese pregnant women. METHODS: Enrolment GA was determined based on last menstrual period, confirmed by first-trimester ultrasound. Maternal anthropometry and fundal height (FH) were measured by a standardised protocol at study visits; FH alone was additionally abstracted from medical charts. Neonatal anthropometry measurements were obtained at birth. To estimate GA at delivery, we developed three predictor models using longitudinal FH alone and with maternal and neonatal anthropometry. For all predictors, we repeatedly sampled observations to construct training (60%) and test (40%) sets. Linear mixed models incorporated longitudinal maternal anthropometry and a shared parameter model incorporated neonatal anthropometry. We assessed models' accuracy under varied scenarios. MAIN OUTCOME MEASURES: Estimated GA at delivery. RESULTS: Prediction error for various combinations of anthropometric measures ranged between 13.9 and 14.9 days. Longitudinal FH alone predicted GA within 14.9 days with relatively stable prediction errors across individual race/ethnicities [whites (13.9 days), blacks (15.1 days), Hispanics (15.5 days) and Asians (13.1 days)], and correctly identified 75% of preterm births. The model was robust to additional scenarios. CONCLUSIONS: In low-risk, non-obese women, longitudinal FH measures alone can provide a reasonably accurate assessment of GA when ultrasound measures are not available. TWEETABLE ABSTRACT: Longitudinal fundal height alone predicts gestational age at birth when ultrasound measures are unavailable. PMID- 29473292 TI - Polyphenolic Compounds Alter Stress-Induced Patterns of Global DNA Methylation in Brain and Blood. AB - SCOPE: Stress is a known contributor to various forms of disease in humans and animals, although mechanisms are still unknown. In animals, psychosocial stress induced depression/anxiety phenotypes are coincidental with increased inflammation in both brain and blood. The authors recently showed that a novel treatment with a select bioactive polyphenol preparation promotes resilience to stress-mediated depression/anxiety phenotypes mice. Moreover, selective bioactive phenolic compounds within the polyphenol preparation are identified that are effective in mitigating the behavioral effects of bone marrow transplantation from stressed mice. METHODS AND RESULTS: Here, an animal model of adult stress and bone marrow transplantation is used to identify an epigenetic signature of repeated social defeat stress (RSDS) that is passed through bone marrow hematopoietic progenitor cells to naive mice, revealing the maintenance of epigenetic memory following stress both centrally and peripherally. Further, polyphenols are administered to naive and stress-susceptible mice, demonstrating that polyphenol treatment in mice from both susceptible and naive donors alters global DNA methylation in the central nervous system and periphery and likewise has an effect on human blood cells after immune challenge. CONCLUSIONS: Findings highlight the enduring molecular memory of stress and the possible mechanism by which select bioactive polyphenols may promote resiliency to stress. Polyphenols may be an efficacious alternative to traditional pharmacological treatments in psychiatry. PMID- 29473293 TI - Highly Sensitive and Stretchable Resistive Strain Sensors Based on Microstructured Metal Nanowire/Elastomer Composite Films. AB - High sensitivity and high stretchability are two conflicting characteristics that are difficult to achieve simultaneously in elastic strain sensors. A highly sensitive and stretchable strain sensor comprising a microstructured metal nanowire (mNW)/elastomer composite film is presented. The surface structure is easily prepared by combining an mNW coating and soft-lithographic replication processes in a simple and reproducible manner. The densely packed microprism array architecture of the composite film leads to a large morphological change in the mNW percolation network by efficiently concentrating the strain in the valley regions upon stretching. Meanwhile, the percolation network comprising mNWs with a high aspect ratio is stable enough to prevent electrical failure, even under high strains. This enables the sensor to simultaneously satisfy high sensitivity (gauge factor ~81 at >130% strain) and high stretchability (150%) while ensuring long-term reliability (10 000 cycles at 150% strain). The sensor can also detect strain induced by bending and pressure, thus demonstrating its potential as a versatile sensing tool. The sensor is successfully utilized to monitor a wide range of human motions in real time. Furthermore, the unique sensing mechanism is easily extended to detect more complex multiaxial strains by optimizing the surface morphology of the device. PMID- 29473294 TI - Fast Postmoisture Treatment of Luminescent Perovskite Films for Efficient Light Emitting Diodes. AB - Despite the recent advances in the performance of perovskite light-emitting diodes (PeLEDs), the effects of water on the perovskite emissive layer and its electroluminescence are still unclear, even though it has been previously demonstrated that moisture has a significant impact on the quality of perovskite films in the fabrication process of perovskite solar cells and is a prerequisite for obtaining high-performance PeLEDs. Here, the effects of postmoisture on the luminescent CH3 NH3 PbBr3 (MAPbBr3 ) perovskite films are systematically investigated. It is found that postmoisture treatment can efficiently control the morphology and growth of perovskite films and only a fast moisture exposure at a 60% high relative humidity results in significantly improved crystallinity, carrier lifetime, and photoluminescence quantum yield of perovskite films. With the optimized moisture-treated perovskite films, a high-performance PeLED is fabricated, exhibiting a maximum current efficiency of 20.4 cd A-1 , which is an almost 20-fold enhancement when compared with perovskite films without moisture treatment. The results provide valuable insights into the moisture-assisted growth of luminescent perovskite films and will aid in the development of high performance perovskite light-emitting devices. PMID- 29473295 TI - Bayesian joint modelling of benefit and risk in drug development. AB - To gain regulatory approval, a new medicine must demonstrate that its benefits outweigh any potential risks, ie, that the benefit-risk balance is favourable towards the new medicine. For transparency and clarity of the decision, a structured and consistent approach to benefit-risk assessment that quantifies uncertainties and accounts for underlying dependencies is desirable. This paper proposes two approaches to benefit-risk evaluation, both based on the idea of joint modelling of mixed outcomes that are potentially dependent at the subject level. Using Bayesian inference, the two approaches offer interpretability and efficiency to enhance qualitative frameworks. Simulation studies show that accounting for correlation leads to a more accurate assessment of the strength of evidence to support benefit-risk profiles of interest. Several graphical approaches are proposed that can be used to communicate the benefit-risk balance to project teams. Finally, the two approaches are illustrated in a case study using real clinical trial data. PMID- 29473296 TI - Community-based lymphedema risk reduction programs for cancer survivors: An Internet survey of public health nurses. AB - AIM: Currently, there is no provision for continuous care to monitor lymphedema risk-reduction behavior for survivors of cancer. The aim was to explore the possibility of community-based lymphedema education programs by investigating the knowledge, training needs, and intention to organize such programs and barriers among government-employed public health nurses. METHODS: A cross-sectional Internet survey was conducted among government-employed public health nurses in Japan. The participants were recruited from 2841 health center and community health centers. RESULTS: The final sample included 641 government-employed public health nurses. The participants' knowledge about lymphedema risk-reduction strategies was relatively good, especially on the importance of observation, detection of early signs, and referral to lymphedema clinics. A small proportion of participants indicated an intention to organize community-based lymphedema education programs. Three determinants for this intention were identified: a general interest in lymphedema education, past experience of undertaking training in lymphedema risk-reduction strategies, and the perceived difficulty in organizing community-based lymphedema education programs. The participants' perceptions of difficulty included not knowing the needs for lymphedema education in their community with survivors of cancer. CONCLUSIONS: The results suggest that working collaboratively with government-employed public health nurses to organize community-based lymphedema education programs is possible. Achieving this requires further investigation of the needs of survivors of cancer in the community, communicating these needs to governmental agencies, and organizing and delivering comprehensive training programs about lymphedema risk-reduction strategies for government-employed public health nurses. PMID- 29473297 TI - Promoting collaboration in emergency medicine. AB - BACKGROUND: Collaborative practice between paramedics and medical staff is essential for ensuring the safe handover of patients. Handover of care is a critical time in the patient journey, when effective communication and collaborative practice are central to promoting patient safety and to avoiding medical error. To encourage effective collaboration between paramedic and medical students, an innovative, practice-based simulation exercise, known as interprofessional clinical skills (ICS) was developed at the University of East Anglia, UK. Emphasising patient safety, effective handover of care and teamwork, within the context of emergency medicine, the ICS promotes collaborative practice amongst health care students through the use of high- and low-fidelity simulation, human factors and values-based practice. METHODS: A total of 123 undergraduate students from paramedic (60) and medical backgrounds (63) took part in the ICS. Evaluation data were collected from all students through the completion of an internal feedback/satisfaction questionnaire with 13 statements and one open-ended comment box. RESULTS: The response rate for the questionnaire was 100%. Of the 123 students from paramedic and medical disciplines, 99% agreed or strongly agreed with the statement 'I enjoyed this session'. Students also felt that the ICS helped them to build mutual respect (98%), enhance understanding of roles (94%) and develop as collaborative practitioners (92%). Collaborative practice between paramedics and medical staff is essential CONCLUSION: The ICS is an innovative, enjoyable and meaningful intervention for promoting interprofessional collaborative practice between paramedic and medical students in a simulated practice setting. It encourages students to gain core training in clinical skills and patient safety, within a safe, supervised environment. PMID- 29473298 TI - Thermoelectric Effects of Nanogaps between Two Tips. AB - This study designs a microscaled thermoelectric component featuring a nanogap of varying size (133-900 nm) between the tips of the component. Electricity and heat are transmitted between the gap of the tips through the thermionic emission of electrons. Because the gaps exhibit a discontinuous structure, the phonon's contribution to thermal conductivity can be virtually neglected, thereby enhancing the thermoelectric figure of merit (ZT) of the designed thermoelectric component. The experimental results reveal that a narrow tip gap generates stronger thermoelectric effects, with Seebeck voltage and Seebeck coefficient being respectively, one and two orders of magnitude greater than those of the thermoelectric effects of nanowires. The thermoelectric figure of merit without considering the contributions from other heat carriers is higher than the value of thermoelectric devices developed in recent years. For a set of asymmetrical thin film electrodes of differing sizes, the thermoelectric effects generated in the heating process of large thin films are stronger than those of small thin films. Furthermore, adding nanoparticles to the nanogap facilitate the thermionic emission of electrons, in which electrons hop from the hot end to the cold end, thereby intensifying the thermoelectric effects of the nanogap. PMID- 29473299 TI - Short-Wave Infrared Sensor by the Photothermal Effect of Colloidal Gold Nanorods. AB - Photodetection in the short-wave infrared (SWIR) spectrum is a challenging task achieved often by costly low bandgap compound semiconductors involving highly toxic elements. In this work, an alternative low-cost approach is reported for SWIR sensors that rely on the plasmonic-induced photothermal effect of solution processed colloidal gold nanorods (Au NRs). A series of uniform solution processed Au NRs of various aspect ratios are prepared exhibiting a strong and well-defined longitudinal localized surface plasmon resonance (L-LSPR) maximum from 900 nm to 1.3 um. A hybrid device structure is fabricated by applying Au NRs on the surface of a thermistor. Under a monochromatic illumination, hybrid Au NR/thermistor devices exhibit a clear photoresponse in the form of photoinduced resistance drop in the wavelength window from 1.0 to 1.8 um. The photoresponsivity of such hybrid devices reaches a maximum value of 4.44 * 107 Omega W-1 at lambda = 1.4 um (intensity = 0.28 mW cm-2 ), a wavelength in agreement with the L-LSPR of the Au NRs applied. Colloidal Au NRs, capable to perform fast conversion between photon absorption and thermal energy, thus open an interesting avenue for alternative low-cost SWIR photodetection. PMID- 29473300 TI - Review article: Managing medical emergencies in rural Australia: A systematic review of the training needs. AB - The aim of the study was to determine the training needs of doctors managing emergencies in rural and remote Australia. A systematic review of Australian articles was performed using MEDLINE (OVID) and INFORMIT online databases from 1990 to 2016. The search terms included 'Rural Health', 'Emergency Medicine', 'Emergency Medical Services', 'Education, Medical, Continuing' and 'Family Practice'. Only peer-reviewed articles, available in full-text that focussed on the training needs of rural doctors were reviewed. Data was extracted using pre defined fields such as date of data collection, number of participants, characteristics of participants, location and study findings. A total of eight studies published from 1998 to 2006 were found to be suitable for inclusion in the analysis. Six studies cited the results of self-reported questionnaires and surveys, one used a telephone questionnaire on a hypothetical patient and one utilised a theoretical examination. The studies found a significant proportion of participants wanted more emergency training. Junior rural doctors were found to have deficiencies in knowledge about stroke. Emergency skills doctors wanted more training including: emergency ultrasound, paediatric/neonatal procedures and cricothyroidotomy. However, many of the studies were performed by training providers that may benefit from deficient results. Given that the data was over 10 years old and that advances have been made in knowledge, training opportunities and technology, the implications for current training needs of rural doctors in Australia could not be accurately assessed. Thus there is a need for further research to identify current training needs. PMID- 29473301 TI - A novel ultra high-performance liquid chromatography-tandem mass spectrometry method for the simultaneous determination of xanthones and steroidal saponins in crude and salt-processed Anemarrhenae Rhizoma aqueous extracts. AB - We established a rapid and sensitive ultra high-performance liquid chromatography tandem mass spectrometry method for the simultaneous quantification of xanthones and steroidal saponins in rat plasma. Chromatographic separation was achieved on a C18 column with a mobile phase comprising acetonitrile and 0.1% formic acid. The detection was performed by negative electrospray ionization in multiple reaction monitoring mode. The validated method showed good linearity within the tested range (r > 0.9945). The intra- and interday precision at high, medium, and low concentrations was less than 7.96%. The bias of accuracies ranged from -1.92 to 9.62%. The extraction recoveries of the compounds ranged from 84.78 to 88.69%, and the matrix effects ranged from 96.76 to 108.59%. This method was successfully applied to a pharmacokinetic comparison of crude and salt-processed Anemarrhenae Rhizoma aqueous extracts after oral administration in rats. The maximum plasma concentration and area under concentration-time curve of timosaponin BIII and timosaponin AIII increased significantly (P < 0.05 or 0.01) and those of timosaponin BII decreased significantly (P < 0.05) after processing. These results could contribute to the clinical application of crude and salt-processed Anemarrhenae Rhizoma and reveal the processing mechanism.

AB - The utility of non-enhanced magnetic resonance imaging (MRI) has not been examined extensively for diagnosing acute pyelonephritis (APN) in children. The aims of this study were to compare non-enhanced MRI with technetium-99 m dimercaptosuccinic acid (99m Tc-DMSA) renal scintigraphy in detecting APN. Six boys and one girl with temperature >=38 degrees C and positive urine culture received both non-enhanced MRI with whole body diffusion-weighted imaging (DWI) and 99m Tc-DMSA scintigraphy <=7 days from the fever onset. The sensitivity and specificity of MRI in detecting APN lesions diagnosed on 99m Tc-DMSA scintigraphy were 80% and 100%, respectively. Non-enhanced MRI in children with suspected APN <=7 days from fever onset might be a suitable replacement for 99m Tc-DMSA scintigraphy for the detection of APN.

AB - Hollow nanostructures with mesoporous shells are attractive for their advantageous structure-dependent high-efficiency electrochemical catalytic performances. In this work, a novel nanostructure of Fe-doped CoP hollow triangle plate arrays (Fe-CoP HTPAs) with unique mesoporous shells is designed and synthesized through a room-temperature postsynthetic ligand exchange reaction followed by a facile phosphorization treatment. The mild postsynthetic ligand exchange reaction of the presynthesized ZIF-67 TPAs with K4 [Fe(CN)6 ] in an aqueous solution at room temperature is of critical importance in achieving the final hollow nanostructure, which results in the production of CoFe(II)-PBA HTPAs that not only determine the formation of the interior voids in the nanostructure, but also provide the doping of Fe atoms to the CoP lattice. As expected, the as prepared mesoporous Fe-CoP HTPAs exhibit pronounced activity for water splitting owing to the advantages of abundant active reaction sites, short electron and ion pathways, and favorable hydrogen adsorption free energy (DeltaGH* ). For the hydrogen and oxygen evolution reactions with the Fe-CoP HTPAs in alkaline medium, the low overpotentials of 98 and 230 mV are observed, respectively, and the required cell voltage toward overall water splitting is only as low as 1.59 V for the driving current density of 10 mA cm-2 . PMID- 29473309 TI - Efficacy of mirabegron for overactive bladder with human T cell lymphotropic virus-1 associated myelopathy. AB - OBJECTIVE: Mirabegron is widely considered as an effective and safe drug for patients with overactive bladder (OAB). However, there is no evidence regarding the efficacy of mirabegron in human T cell lymphotropic virus-1 (HTLV-1) associated myelopathy/tropical spastic paraparesis (HAM/TSP) patients with OAB symptoms. The aim of the present study was to clarify the efficacy of mirabegron in HAM/TSP patients with OAB symptoms. METHODS: The present study evaluated the efficacy of mirabegron treatment (50 mg, once daily) in nineteen HAM/TSP patients with OAB symptoms by assessing subjective symptoms using the overactive bladder symptom score (OABSS) and International Prostate Symptom Score (IPSS) before and 12 weeks after administration. Voided volume (VV), maximum flow rate (Qmax ), and post-void residual (PVR) urine volume were evaluated as objective symptoms. RESULTS: Mirabegron treatment improved OABSS in terms of night-time frequency, urgency, and total score (P < .001). In addition, on the IPSS, mirabegron therapy improved urgency, nocturia, storage symptoms (Questions 2, 4 and 7 on the IPSS), as well as the total score (P < .001). The quality of life (QoL) on the IPSS also improved after treatment (P < .001). However, there were no significant changes in objective symptoms, as measured by VV, Qmax , and PVR, after treatment. One patient (5.3%) complained of dry mouth; because this adverse effect was very mild, the patient did not discontinue mirabegron. CONCLUSIONS: Mirabegron administration improved subjective symptoms in HAM/TSP patients with neurogenic OAB.

PMID- 29473312 TI - Method for the simultaneous determination of monoaromatic and polycyclic aromatic hydrocarbons in industrial effluents using dispersive liquid-liquid microextraction with gas chromatography-mass spectrometry. AB - We present a new method for simultaneous determination of 22 monoaromatic and polycyclic aromatic hydrocarbons in postoxidative effluents from the production of petroleum bitumen using dispersive liquid-liquid microextraction coupled to gas chromatography and mass spectrometry. The eight extraction parameters including the type and volume of extraction and disperser solvent, pH, salting out effect, extraction, and centrifugation time were optimized. The low detection limit ranging from 0.36 to 28 MUg/L, limit of quantitation (1.1-84 MUg/L), good reproducibility, and wide linear ranges, as well as the recoveries ranging from 71.74 to 114.67% revealed that the new method allows the determination of aromatic hydrocarbons at low concentration levels in industrial effluents having a very complex composition. The developed method was applied to the determination of content of mono- and polycyclic aromatic hydrocarbons in samples of raw postoxidative effluents in which 15 compounds were identified at concentrations ranging from 1.21 to 1017.0 MUg/L as well as in effluents after chemical treatment. PMID- 29473311 TI - HER3 expression is enhanced during progression of lung adenocarcinoma without EGFR mutation from stage 0 to IA1. AB - BACKGROUND: Activating EGFR mutations, HER2, and HER3 are implicated in lung cancer; however, with the exception of EGFR gene amplification in lung adenocarcinoma harboring EGFR mutations, their involvement in disease progression during the early stages is poorly understood. In this paper, we focused on which receptor is correlated with lung adenocarcinoma progression in the presence or absence of EGFR mutation from stage 0 to IA1. METHODS: HER2 and HER3 expression and activating EGFR mutations in surgically resected lung adenocarcinoma exhibiting ground glass nodules on chest computed tomography and re-classified to stage 0 and IA1 were examined by immunohistochemistry and peptide nucleic acid locked nucleic acid PCR clamp method, respectively. RESULTS: HER2 and HER3 expression was detected in 22.2% and 86.1% of samples, respectively. The frequency of EGFR mutation was 45.7% and was not significantly different between stage 0 and IA1 (40.0% and 48.0%, respectively), suggesting that EGFR mutation does not correlate with cancer progression from stage 0 to IA1. HER2 expression also did not correlate to progression. However, not only the frequency, but also the intensity of HER3 expression was increased in stage IA1 lung adenocarcinoma, particularly in lung adenocarcinoma without EGFR mutation. CONCLUSION: HER3 tends to be intensively expressed during the progression of lung adenocarcinoma without EGFR mutation from carcinoma in situ to invasive carcinoma.

After the ENB registration process, the anesthetist changed the single-lumen endotracheal tube to a double-lumen endobronchial tube. Guided by the ENB system, the operator delivered the probe of the locatable guide to the planned site through the right lumen of the endobronchial tube. The ENB system allows calculation of the direction and distance between the probe and the lesion, confirming the relative location of the lesion. The locatable guide was retained during surgery as an intraoperative indicator, rather than applying dye marking. During video-assisted thoracoscopic surgery, the protuberant visceral pleura poked by the probe accurately indicated the relative location of the lesion. Accordingly, we performed precise wedge resection for diagnosis, followed by lobectomy, resulting in a diagnosis of invasive adenocarcinoma. Vectorial localization is an alternative method of ENB-guided localization to peripheral pulmonary lesions, which can provide the accurate location of such lesions for diagnostic surgical resection.

AB - The aim of this study was to analyse how protracted exposure to X-rays delivered at low dose rates of 0.0032-0.052 kGy h-1 affects the survival and metabolic activity of two microfungi capable of melanogenesis: fast-growing Cryptococcus neoformans (CN) and slow-growing Cryomyces antarcticus (CA). Melanized CN and CA cells survived the protracted exposure better than non-melanized ones, which was consistent with previous reports on the radioprotective role of melanin in these fungi after high dose rate exposures. The survival data were described by the linear quadratic dose response model. The XTT metabolic profiles were practically identical for melanized CN and CA with activity dose-dependent increasing: no changes in the activity of the non-melanized CN and CA were recorded by this assay. In contrast, the MTT assay, which measures the intracellular energy related processes, recorded an increase in activity of non-melanized CN and CA cells, but not in their melanized counterparts. This could reflect intensive repair processes initiated by the non-melanized cells post exposure. This study suggests that differences in radiation responses between melanized and non melanized fungal cells occur over a wide range of radiation dose rates. PMID- 29473315 TI - Photophysics and Photocatalysis of Melem: A Spectroscopic Reinvestigation. AB - Graphitic carbon nitride (g-CN) is one potential metal-free photocatalyst. The photocatalytic mechanism of g-CN is related to the heptazine ring building unit. Melem is the simplest heptazine-based compound and g-CN is its polymeric product. Thus, studies on the photophysical properties of melem will help to understand the photocatalytic mechanism of heptazine-based materials. Herein, the spectroscopic features of melem were systematically explored through measuring its absorption spectrum, fluorescence spectrum, and fluorescence decay. Both fluorescence spectroscopy and fluorescence decay measurements show that the condensation of melamine to melem causes stronger photoluminescence, whereas the condensation of melem to g-CN causes weaker photoluminescence. In addition, all observations reveal that a mixture of monomer melem and its higher condensates is more easily obtained during the preparation of melem, and that the higher condensates of melem affect the photophysical properties of melem dominantly. The photocatalytic hydrogen evolution of melem has also been measured and the monomer melem has negligible photoinduced water-splitting activity.

AB - Glioma is the most common intracranial malignant tumors, accounting for about 40% of intracranial tumors. Primary or secondary drug resistance is one of the main reasons for the failure of treatment. The oncogenic or tumor-suppressive roles of miR-634 have been revealed in different types of cancer. However, the role of miR 634 in glioma remains unknown and whether miR-634 could sensitize glioma cells to temozolomide also is unclear. Here, we aim to investigate the biological function of miR-634 and the possible mechanisms in glioma. In this study, we found that miR-634 was downregulated in glioma tissues compared with normal brain tissues, and its expression was associated with tumor size and WHO grade. Importantly, glioma patients with low miR-634 expression showed a shorter survival time than patients which had high expression of miR-634. This study also showed that miR 634 was decreased in temozolomide-resistant glioma cells, and restoration of miR 634 could sensitize the resistant cells to temozolomide by targeting CYR61 through Raf-ERK signaling. Our study provides a potential target for overcome drug resistance in glioma. PMID- 29473319 TI - Prognostic variables for temporal lobe injury after intensity modulated radiotherapy of nasopharyngeal carcinoma. AB - To determine predictive factors for temporal lobe injury (TLI) in nasopharyngeal carcinoma patient (NPC) treated with intensity-modulated radiation therapy (IMRT). A total of 695 NPC cases treated with IMRT were retrospectively analyzed. TLI was diagnosed on MRI images. Volume-dose histograms for 870 evaluable temporal lobes were analyzed, and the predictive factors for the occurrence of TLI was evaluated. Receiver operating characteristic curve (ROC) and Logistic regression analysis was used to determine volume-dose parameters that predict temporal lobe injury (TLI). Univariate and multivariate analysis were used to analyze the predictive factors for TLI. The radiation dose-tolerance model of temporal lobe was calculated by logistic dose-response model. The median follow up time was 73 months. A total of 8.5% patients were diagnosed with TLI. Among all the volume-dose parameters, logistic regression model showed D2cc (the dose Gray delivered to 2 cubic centimeter volume) was an only independent predictive factor. Multivariate analysis showed D2cc of temporal lobe, fraction size of prescription, T stage, and chemotherapy were the independent predictive factors for TLI. Logistic dose-response model has indicated the TD5/5 and TD50/5 of D2cc are 60.3 Gy and 76.9 Gy, respectively. D2cc of temporal lobe, fraction size of prescription, T stage, and chemotherapy were the possible independent predictive factors for TLI after IMRT of NPC. Biologic effective doses (TD5/5 and TD50/5 ) of D2cc are considered to prevent TLI. PMID- 29473318 TI - First report on characterization and pathogenicity study of emerging Lactococcus garvieae infection in farmed rainbow trout, Oncorhynchus mykiss (Walbaum), from India. AB - "Warm water lactococcosis" in farm-reared rainbow trout, Oncorhynchus mykiss (Walbaum) in the northern Himalayan region of India, caused by bacterium Lactococcus garvieae is described in this study. Nine bacterial isolates were recovered from the organs of haemorrhagic septicaemia rainbow trout and were subjected to biochemical and molecular identification. Cell surface characteristics and virulence of the bacterial isolates are also described. All the nine bacterial isolates had homogenous biochemical characteristics and were Gram-positive, short chains forming (two to eight cells long), alpha-haemolytic, non-motile ovoid cocci. Partial 16S rDNA nucleotide sequence (~1,400 bp) of current isolates shared 99% identities with the 16S rDNA nucleotide sequence of L. garvieae R421, L. garvieae FMA395 and L. garvieae CAU:1730. The identity of the bacterial isolates was further confirmed by PCR amplification of L. garvieae specific ~1,100 bp fragment. Transmission electron microscopy (TEM) of one representative isolate, L. garvieae RTCLI04, indicates that the isolated strain lacks thick outer capsule and is of KG+ (non-capsulates) phenotype. An intraperitoneal and intramuscular injection (2.6 * 105 CFU ml-1 ) and also immersion in bacterial suspension @ of 2.6 * 105 CFU ml-1 to healthy rainbow trout juveniles (body weight: 27.5 +/- 3.7 g) with L. garvieae RTCLI04 caused 80%, 60% and 10% cumulative mortality in challenged fish, respectively, within 15 days post-infection. The haemorrhagic septicaemic disease was reproduced experimentally. Histopathological examination of organs of experimentally infected fish revealed extensive degenerative and inflammatory changes in eye, kidney, gill and liver. PCR amplification of several putative virulence genes such as haemolysins, adhesins, LPxTG-containing surface proteins and adhesins cluster confirms the virulence of our Indian L. garvieae isolates. To the best of our knowledge, we are reporting for the first time that L. garvieae is associated with fatal haemorrhagic septicaemia in farmed rainbow trout in India. PMID- 29473321 TI - Reliability of autonomic and vascular components of baroreflex sensitivity in adolescents. AB - Improvements in the autonomic and vascular systems are implicated in cardiovascular disease risk reduction. Baroreflex sensitivity (BRS) is composed of vascular and autonomic components. This study aimed to investigate between- and within-day reliability of BRS and its autonomic and vascular determinants in adolescents. Thirteen male adolescents (14.1 +/- 0.5 y) participated in this study. For between-day reliability, participants completed four experimental visits separated by a minimum of 48-h. For within-day reliability, participants repeated BRS assessments three times in the morning with one hour between the measures. BRS was evaluated using the cross-spectral gain (LFgain) between blood pressure and heart rate interval. BRS was further divided into: 1) vascular component using arterial compliance (AC); and 2) autonomic component measured as LFgain divided by AC (LFgain/AC). LFgain, AC and LFgain/AC presented between-day coefficient of variation (CV) of 20%, 17%, and 20%, respectively. Similarly, variables associated with blood pressure control, such as cardiac output, mean arterial pressure, heart rate and total peripheral resistance, presented CVs ranging from 6% to 15%. Within-day reliability was poorer compared to between-day for LFgain (25%), AC (25%), and LFgain/AC (31%), as well as all hemodynamic variables (CVs from 11% to 22%, except heart rate with presented CV of 6%). This study indicates suitable between- and within-reliability of BRS and its autonomic and vascular determinants, as well as hemodynamic variables associated with BRS, in adolescents. PMID- 29473320 TI - Epigenetic silencing of RNF144A expression in breast cancer cells through promoter hypermethylation and MBD4. AB - Emerging evidence shows that ring finger protein 144A (RNF144A), a poorly characterized member of the Ring-between-Ring (RBR) family of E3 ubiquitin ligases, is a potential tumor suppressor gene. However, its regulatory mechanism in breast cancer remains undefined. Here, we report that RNF144A promoter contains a putative CpG island and the methylation levels of RNF144A promoter are higher in primary breast tumors than those in normal breast tissues. Consistently, RNF144A promoter methylation levels are associated with its transcriptional silencing in breast cancer cells, and treatment with DNA methylation inhibitor 5-Aza-2-deoxycytidine (AZA) reactivates RNF144A expression in cells with RNF144A promoter hypermethylation. Furthermore, genetic knockdown or pharmacological inhibition of endogenous methyl-CpG-binding domain 4 (MBD4) results in increased RNF144A expression. These findings suggest that RNF144A is epigenetically silenced in breast cancer cells by promoter hypermethylation and MBD4. PMID- 29473322 TI - A method to identify the areas at risk for the introduction of avian influenza virus into poultry flocks through direct contact with wild ducks. AB - Wild dabbling ducks are the main reservoir for avian influenza (AI) viruses and pose an ongoing threat to commercial poultry flocks. Combining the (i) size of that population, (ii) their flight distances and (iii) their AI prevalence, the density of AI-infected dabbling ducks (DID) was calculated as a risk factor for the introduction of AI viruses into poultry holdings of Emilia-Romagna region, Northern Italy. Data on 747 poultry holdings and on 39 AI primary outbreaks notified in Emilia-Romagna between 2000 and 2017 were used to validate that risk factor. A multivariable Bayesian logistic regression was performed to assess whether DID could be associated with the occurrence of AI primary outbreaks. DID value, being an outdoor flock, hobby poultry trading, species reared, length of cycle and flock size were used as explanatory variables. Being an outdoor poultry flock was significantly associated with a higher risk of AI outbreak occurrence. The probability of DID to be a risk factor for AI virus introduction was estimated to be 90%. A DID cut-off of 0.23 was identified to define high-risk areas for AI virus introduction. Using this value, the high-risk area covers 43% of the region. Seventy-four per cent of the primary AI outbreaks have occurred in that area, containing 39% of the regional poultry holdings. Poultry holdings located in areas with a high DID value should be included in a risk-based surveillance programme aimed at AI early detection. PMID- 29473323 TI - Adult spinal opioid receptor MU1 expression after incision is altered by early life repetitive tactile and noxious procedures in rats. AB - Clinical and experimental data suggests that noxious stimulation at critical stages of development results in long-term changes on nociceptive processing in later life. Here, we use an established, well-documented rat model of repetitive noxious procedures closely mimicking the clinical situation in the NICU. In order to understand molecular changes underlying the long-term consequences of repetitive stimulation of the developing nociceptive system the present study aims to analyze the presence of the u-opioid-receptor-1 (OPRM1). Neonatal rats received either four needle pricks per day in the left hind-paw from postnatal day 0-7 as a model of procedural pain in infancy. Control pups were handled in the same way but were instead tactile stimulated, or were left undisturbed. At the age of 8 weeks, all animals received an ipsilateral hind-paw incision as a model for post-operative pain, and mechanical sensitivity was tested at multiple time-points. Before, and 1 or 5 days post-incision, spinal cord tissue was collected for immunostaining of opioid receptor OPRM1. Semi-quantitative immunocytochemical analysis of superficial laminae in lumbar spinal dorsal horn revealed that: (1) early life repetitive tactile or noxious procedures do not alter baseline levels of OPRM1 staining intensity and (2) early life repetitive tactile or noxious procedures lead to a decrease in OPRM1 staining intensity 5 days after incision in adulthood compared to undisturbed controls. We conclude that early life repetitive tactile or noxious procedures affect the intensity of OPRM1-immunoreactivity in the lumbar superficial spinal cord dorsal horn after adulthood injury, without affecting baseline intensity.

AB - The With-No-Lysine (WNK) serine/threonine kinase family constitutes a unique and distinctive branch of the kinome. The four proteins of this family (WNK1/2/3/4) are involved in blood pressure regulation, body fluid, and electrolyte homeostasis. Herein, we modeled and analyzed the binding modes of all publicly available small orthosteric and allosteric binders (including WNK463 and WNK467) experimentally tested towards any of the WNK family member. To do so, we relied on state-of-the-art cheminformatics approaches including structure-based molecular docking and molecular dynamics simulations. In particular, we computed and analyzed the (i) molecular selectivity of known inhibitors when docked in the binding site of each WNK family member, (ii) the dynamic WNK-inhibitor interactions at both orthosteric and allosteric sites to derive new structure activity relationships, and (iii) the key specific interactions present in each binding site. This study reports on the first, cheminformatics-powered analysis of the entire chemical space of known WNK inhibitors. We discuss the conservation of critical WNK-inhibitor interactions and the existence of isoform-specific interactions that could enable the rational design of more potent and selective WNK binders. PMID- 29473324 TI - Establishment and characterization of in vivo orthotopic bioluminescent xenograft models from human osteosarcoma cell lines in Swiss nude and NSG mice. AB - Osteosarcoma is one of the most common primary bone tumors in childhood and adolescence. Metastases occurrence at diagnosis or during disease evolution is the main therapeutic challenge. New drug evaluation to improve patient survival requires the development of various preclinical models mimicking at best the complexity of the disease and its metastatic potential. We describe here the development and characteristics of two orthotopic bioluminescent (Luc/mKate2) cell-derived xenograft (CDX) models, Saos-2-B-Luc/mKate2-CDX and HOS-Luc/mKate2 CDX, in different immune (nude and NSG mouse strains) and bone (intratibial and paratibial with periosteum activation) contexts. IVIS SpectrumCT system allowed both longitudinal computed tomography (CT) and bioluminescence real-time follow up of primary tumor growth and metastatic spread, which was confirmed by histology. The murine immune context influenced tumor engraftment, primary tumor growth, and metastatic spread to lungs, bone, and spleen (an unusual localization in humans). Engraftment in NSG mice was found superior to that found in nude mice and intratibial bone environment more favorable to engraftment compared to paratibial injection. The genetic background of the two CDX models also led to distinct primary tumor behavior observed on CT scan. Saos-2-B-Luc/mKate2-CDX showed osteocondensed, HOS-Luc/mKate2-CDX osteolytic morphology. Bioluminescence defined a faster growth of the primary tumor and metastases in Saos-2-B Luc/mKate2-CDX than in HOS-Luc/mKate2-CDX. The early detection of primary tumor growth and metastatic spread by bioluminescence allows an improved exploration of osteosarcoma disease at tumor progression, and metastatic spread, as well as the evaluations of anticancer treatments. Our orthotopic models with metastatic spread bring complementary information to other types of existing osteosarcoma models. PMID- 29473326 TI - Prediction of radiotherapy response with a 5-microRNA signature-based nomogram in head and neck squamous cell carcinoma. AB - Radiotherapy is unlikely to benefit all patients with head and neck squamous cell carcinoma (HNSCC). Therefore, novel method is warranted to predict the radiotherapy response. Our study aimed to construct a microRNA (miRNA)-based nomogram to predict clinical outcomes of patients with HNSCC receiving radiotherapy. We screened out 56 differential miRNAs by analyzing 44 paired tumor and adjacent normal samples miRNA expression profiles from The Cancer Genome Atlas (TCGA). A total of 307 patients with HNSCC receiving adjuvant radiotherapy were randomly divided into a training set (n = 154) and a validation set (n = 153). In the training set, we combined the differential miRNA profiles with clinical outcomes, and LASSO regression model was applied to establish a 5-miRNA signature. The prediction accuracy of the 5-miRNA signature was further validated. In addition, target genes of these miRNAs were predicted, and Gene Ontology (GO) analysis as well as KEGG pathway analysis was executed. A 5-miRNA signature including miR-99a, miR-31, miR-410, miR-424, and miR-495 was identified. With a cutoff value of 1.2201 from Youden's index, the training set was divided into high-risk and low-risk groups, and the 5-year overall survival was significantly different (30% vs. 73%, HR 3.65, CI 2.46-8.16; P < 0.0001). Furthermore, our 5-miRNA signature revealed that only low-risk group would benefit from radiotherapy. Then, a nomogram combining 5-miRNA signature with clinical variables to predict radiotherapy response was constructed. The analysis of 108 target genes of these miRNAs revealed some potential mechanisms in HNSCC radiotherapy response for future investigations. In conclusion, the 5-miRNA signature-based nomogram is useful in predicting radiotherapy response in HNSCC and might become a promising tool to optimize radiation strategies. PMID- 29473327 TI - Epidemiological investigation of pseudorabies in Shandong Province from 2013 to 2016. AB - In late 2011, a variant pseudorabies virus (vPRV) emerged in Bartha-K61 vaccinated pig herds, resulting in high morbidity and mortality of piglets in China. Since 2013, the autopsy lesions, histological examinations, virus isolation, phylogenetic analysis and selection pressure analysis of the gE gene of vPRV were recorded for 395 clinical cases, and 5,033 pig serum samples were detected by PRV gE-coated enzyme-linked immunosorbent assay. The major clinical symptoms were abortion in pregnant sows, fatal neurological signs in piglets and respiratory disease in growing pigs. Necrotic splenitis, hepatitis and lymphadenitis, haemorrhagic nephritis and non-suppurative encephalitis were observed by histopathological examination. Typical eosinophilic inclusion bodies were found in the nuclei of liver cells. Using PCR, 110 samples among 395 clinical cases tested positive for the gE gene. Fifteen vPRV strains were isolated and confirmed by sequencing and phylogenetic analysis of the gE gene. The strains shared 97.1%-99.9% nucleotide (nt) and 96.6%-99.5% amino acid (aa) homology with PRV reference strains. Selection pressure analysis showed that one site in the codons of glycoprotein E was under positive selection. Of the 5,033 serum samples, 2,909 were positive by ELISA for a positive rate of 57.8%. These results showed that vPRV was still prevalent in Shandong Province, indicating severe PRV infectious pressure. The preparation of new vaccines against PRV is extremely urgent.

PMID- 29473328 TI - LncRNA HOTAIR influences cell growth, migration, invasion, and apoptosis via the miR-20a-5p/HMGA2 axis in breast cancer. AB - To study the regulatory effect of lncRNA HOTAIR/miR-20a-5p/HMGA2 axis on breast cancer (BC) cell growth, cell mobility, invasiveness, and apoptosis. The microarray data of lncRNAs and mRNAs with differential expression in BC tissues were analyzed in the Cancer Genome Atlas (TCGA) database. LncRNA HOX transcript antisense RNA (lncRNA HOTAIR) expression in BC was assessed by qRT-PCR. Cell viability was confirmed using MTT and colony formation assay. Cell apoptosis was analyzed by TdT-mediated dUTP nick-end labeling (TUNEL) assay. Cell mobility and invasiveness were testified by transwell assay. RNA pull-down and dual luciferase assay were used for analysis of the correlation between lncRNA HOTAIR and miR-20a 5p, as well as relationship of miR-20a-5p with high mobility group AT-hook 2 (HMGA2). Tumor xenograft study was applied to confirm the correlation of lncRNA HOTAIR/miR-20a-5p/HMGA2 axis on BC development in vivo. The expression levels of the lncRNA HOTAIR were upregulated in BC tissues and cells. Knockdown lncRNA HOTAIR inhibited cell propagation and metastasis and facilitated cell apoptosis. MiR-20a-5p was a target of lncRNA HOTAIR and had a negative correlation with lncRNA HOTAIR. MiR-20a-5p overexpression in BC suppressed cell growth, mobility, and invasiveness and facilitated apoptosis. HMGA2 was a target of miR-20a-5p, which significantly induced carcinogenesis of BC. BC cells progression was mediated by lncRNA HOTAIR via affecting miR-20a-5p/HMGA2 in vivo. LncRNA HOTAIR affected cell growth, metastasis, and apoptosis via the miR-20a-5p/HMGA2 axis in breast cancer.

AB - The effective delivery of information literacy training can be a challenging process, and health library and information professionals are constantly innovating in this area. This article presents a case study of the BHSc (Hons) Occupational therapy degree programme at York St John University to demonstrate ways in which deep integration of information skills into the curriculum can be achieved. The article advises that in the delivery of health and social care related information skills, we should look more broadly at where relevant learning can happen. In particular, contexts of the health care environment are suggested as a consideration rather than the narrow scope of the academic, classroom-based environment. Examples are provided of specific teaching and learning activities used on the programme alongside CPD activity and curriculum design. PMID- 29473332 TI - Chromosomal abnormality variation detected by G-banding is associated with prognosis of diffuse large B-cell lymphoma treated by R-CHOP-based therapy. AB - Diffuse large B-cell lymphoma (DLBCL), which is the most prevalent disease subtype of non-Hodgkin lymphoma, is highly heterogeneous in terms of cytogenetic and molecular features. This study retrospectively investigated the clinical impact of G-banding-defined chromosomal abnormality on treatment outcomes of DLBCL in the era of rituximab-containing immunochemotherapy. Of 181 patients who were diagnosed with DLBCL and treated with R-CHOP or an R-CHOP-like regimen between January 2006 and April 2014, metaphase spreads were evaluable for G banding in 120. In these 120 patients, 40 were found to harbor a single chromosomal aberration type; 63 showed chromosomal abnormality variations (CAVs), which are defined by the presence of different types of chromosomal abnormalities in G-banding, including 19 with two CAVs and 44 with >=3 CAVs; and 17 had normal karyotypes. No specific chromosomal break point or numerical abnormality was associated with overall survival (OS) or progression-free survival (PFS), but the presence of >=3 CAVs was significantly associated with inferior OS rates (hazard ratio (HR): 2.222, 95% confidence interval (CI): 1.056-4.677, P = 0.031) and tended to be associated with shorter PFS (HR: 1.796, 95% CI: 0.965-3.344, P = 0.061). In addition, >=3 CAVs more frequently accumulated in high-risk patients, as defined by several conventional prognostic indices, such as the revised International Prognostic Index. In conclusion, our results suggest that the emergence of more CAVs, especially >=3, based on chromosomal instability underlies the development of high-risk disease features and a poor prognosis in DLBCL. PMID- 29473333 TI - Risk factors and survival outcomes in patients with breast cancer and lung metastasis: a population-based study. AB - The risk factors for morbidity and mortality in breast cancer lung metastases (BCLM) patients still remain poorly identified. The aim of this study was to assess the incidence and survival of BCLM and associated risk factors. Patients with BCLM were identified from the Surveillance, Epidemiology, and End Results (SEER) database. Multivariate logistic regression analysis was used to determine the risk factors for BCLM. Predictors of factors associated with death were analyzed in Cox regression and Fine and Gray's test. Of the 11568 patients with stage IV breast cancer, 4213 (36.4%) had BCLM and 1214 (10.5%) had metastases confined to lungs. The median survival time for patients with BCLM was 21 months, and 15.5% of the patients were alive more than 3 years. The tumor subtype distribution was 45.3% HR- /HER2- , 12.2% HR+ /HER2+ , 7.8% HR- /HER2+, and 15.0% triple-negative subtype. Compared with patients without BCLM, those with BCLM were more likely to be aged, female, black, higher tumor grade, HR- /HER2+ , HR+ /HER2+, and triple-negative subtypes at diagnosis. Survival analysis showed that the aged, black race, HR- /HER2+ , triple-negative subtype, higher grade were the independent risk factor for BCLM patients' survival, while HR+ /HER2+ subtype, insured status, and married status suggested better prognosis. In conclusion, the incidence and prognosis of BCLM varied by tumor subtypes, age, and race. Elderly patients with HER2-positive or triple-negative tumors were more likely to have BCLM. PMID- 29473334 TI - Treatment-related mortality in newly diagnosed pediatric cancer: a population based analysis. AB - Using a previously developed reliable and valid treatment-related mortality (TRM) definition, our objective was to describe the proportion of children newly diagnosed with cancer experiencing TRM and to identify risk factors for TRM in a population-based cohort. We included children with cancer <19 years diagnosed and treated in Ontario who were diagnosed between 2003 and 2012. Children with cancer were identified using data in a provincial registry. Cumulative incidence of TRM was calculated where progressive disease death was considered a competing event. Among the 5179 children included, 179 had TRM, 478 died of progressive disease, and 4522 were still alive. At 5 years, the cumulative incidence of TRM among the entire cohort was 3.9% (95% confidence interval (CI) 3.3-4.5%). When compared to brain tumor patients, leukemia and lymphoma patients had a significantly higher risk of TRM (hazard ratio (HR) 2.5, 95% CI: 1.6-4.0; P < 0.0001). Infants were at significantly higher risk of TRM across diagnostic groups. Other factors associated with higher risks of TRM were metastatic disease (P < 0.0001), diagnosis prior to 1 January 2008 (P = 0.001), hematopoietic stem cell transplantation (HSCT) (P < 0.0001), and relapse (P < 0.0001). The 5-year cumulative incidence of TRM was 3.9% among newly diagnosed children with cancer. Infants were at higher risk of TRM across diagnostic groups. Other risk factors for TRM were leukemia or lymphoma, metastatic disease, earlier diagnosis year, HSCT, and relapse. Future work should further refine prognostic factors by specific cancer diagnosis to best understand when and how to intervene to improve outcomes. PMID- 29473335 TI - Leptomeningeal enhancement on preoperative brain MRI in patients with glioblastoma and its clinical impact. AB - AIM: Leptomeningeal enhancement (LME) on preoperative brain magnetic resonance imaging (MRI) does not always indicate leptomeningeal seeding (LMS). With Stupp's regimen, authors have treated glioblastoma patients with LME on preoperative brain MRI but here we tried to find the clinical impact of LME. METHODS: From 2005 to 2015, 290 patients with glioblastoma have been treated with Stupp's regimen at Samsung Medical Center. Among these, 33 patients showed LME on preoperative brain MRI. We compared the clinical outcomes between the patients with or without LME on preoperative brain MRI and analyzed the clinical results according to changes of LME at following MRI. RESULTS: The median survival was 23 months, and 2-year overall survival (OS) and disease-free survival (DFS) rate was 46.3% and 19.6%, respectively. Prognostic factors for OS and DFS were Karnofsky performance status, extent of resection and adjuvant chemotherapy. MGMT promoter methylation status was a significant prognostic factor for DFS. However, LME was not a significant prognostic factor for OS (P = 0.156) or DFS (P = 0.193). Among the 33 patients with LME on preoperative MRI, 21 (63.6%) showed persistent LME at the next MRI. A statistically significant difference in 2-year survival was evident between patients with and without persistent LME (OS, 17.3% and 70.1%, respectively, P = 0.044; DFS, 5.3% and 54.0%, respectively, P = 0.006). The most common pattern of failure was local recurrence. However, patients with persistent LME displayed a higher incidence of LMS than patients without LME. CONCLUSION: LME on preoperative brain MRI did not affect the clinical results in glioblastoma patients treated with the Stupp's regimen. However, persistence of LME was associated with poor survival and high possibility of LMS. For these patients, the postoperative adjuvant treatment should focus on palliative aim or more aggressive treatment scheme should be followed to overcome the disastrous results.

AB - Nanofibers/nanowires usually exhibit exceptionally low flexural rigidities and remarkable tolerance against mechanical bending, showing superior advantages in flexible electronics applications. Electrospinning is regarded as a powerful process for this 1D nanostructure; however, it can only be able to produce chaotic fibers that are incompatible with the well-patterned microstructures in flexible electronics. Electro-hydrodynamic (EHD) direct-writing technology enables large-scale deposition of highly aligned nanofibers in an additive, noncontact, real-time adjustment, and individual control manner on rigid or flexible, planar or curved substrates, making it rather attractive in the fabrication of flexible electronics. In this Review, the ground-breaking research progress in the field of EHD direct-writing technology is summarized, including a brief chronology of EHD direct-writing techniques, basic principles and alignment strategies, and applications in flexible electronics. Finally, future prospects are suggested to advance flexible electronics based on orderly arranged EHD direct-written fibers. This technology overcomes the limitations of the resolution of fabrication and viscosity of ink of conventional inkjet printing, and represents major advances in manufacturing of flexible electronics.

AB - BACKGROUND: The current management paradigm for children with single ventricle heart disease involves a series of palliative surgeries, culminating in the Fontan operation. This physiology results in a high central venous pressure, and in the setting of single ventricle heart disease, results in hepatic injury and fibrosis over time. Fontan-associated liver disease (FALD) is universally present in this cohort, and the current gold standard for diagnosis remains biopsy. Noninvasive assessments of liver fibrosis, such as ultrasound with elastography or acoustic radiation force impulse (ARFI), has been utilized in this cohort. The effect of poor cardiovascular efficiency, as measured by cardiopulmonary exercise test (CPET), on assessments of liver fibrosis remains poorly understood. METHODS: Retrospective, cross-sectional study. Subjects were evaluated in a multidisciplinary clinic setting for patients who have undergone Fontan operation. CPETs, liver ultrasound with elastography (ARFI), and standard laboratory tests were performed as part of routine clinical care pathway. Statistical analysis included linear correlation. RESULTS: There was a poor correlation between mean ARFI velocity and peak oxygen consumption (VO2max ) in this cohort (r = .20, P = NS). Similarly, there was poor correlation between ARFI and biomarkers of liver injury, time since Fontan operation and Fontan pressure. DISCUSSION: ARFI had poor correlation with functional capacity after Fontan, as measured by VO2max obtained during CPET. While a single measurement of liver elastography was not associated with cardiopulmonary efficiency, longitudinal data may reveal an association.

AB - OBJECTIVE: The aim of the present study was to examine the clinical features and implications of a feeling of incomplete emptying despite little post-void residual (PVR), because it remains unclear why patients are bothered by such an undefined feeling. METHODS: Data were collected prospectively from 173 consecutive patients (135 men, 38 women) with a complaint of a feeling of incomplete emptying with PVR <50 mL at an initial visit. The International Prostate Symptom Score (IPSS), quality of life (QoL) score, overactive bladder symptom score (OABSS), prostate volume, and PVR were determined. Subjective symptoms were re-evaluated after 8 weeks of medication for co-occurring urinary symptoms. RESULTS: Most patients presented with high scores for a feeling of incomplete emptying, determined by Item 1 on the IPSS. The score for a feeling of incomplete emptying was positively correlated with all IPSS-related scores. Men with a feeling of incomplete emptying more often had co-occurring voiding symptoms with higher scores than women. Significant symptom relief was achieved for a feeling of incomplete emptying as well as voiding and storage symptoms after treatment. In men, there was a positive correlation between the extent of symptom relief of a feeling of incomplete emptying and voiding symptoms. CONCLUSIONS: A feeling of incomplete emptying with little PVR is frequently observed in routine clinical practice in both men and women, along with voiding and storage symptoms. This feeling was simultaneously improved by medications for co-occurring urinary symptoms. PMID- 29473338 TI - The current state and future perspectives of cannabinoids in cancer biology. AB - To date, cannabinoids have been allowed in the palliative medicine due to their analgesic and antiemetic effects, but increasing number of preclinical studies indicates their anticancer properties. Cannabinoids exhibit their action by a modulation of the signaling pathways crucial in the control of cell proliferation and survival. Many in vitro and in vivo experiments have shown that cannabinoids inhibit proliferation of cancer cells, stimulate autophagy and apoptosis, and have also a potential to inhibit angiogenesis and metastasis. In this review, we present an actual state of knowledge regarding molecular mechanisms of cannabinoids' anticancer action, but we discuss also aspects that are still not fully understood such as the role of the endocannabinoid system in a carcinogenesis, the impact of cannabinoids on the immune system in the context of cancer development, or the cases of a stimulation of cancer cells' proliferation by cannabinoids. The review includes also a summary of currently ongoing clinical trials evaluating the safety and efficacy of cannabinoids as anticancer agents. PMID- 29473340 TI - A nomogram incorporating six easily obtained parameters to discriminate intrahepatic cholangiocarcinoma and hepatocellular carcinoma. AB - Intrahepatic cholangiocarcinoma (ICC) and hepatocellular carcinoma (HCC) are the most prevalent histologic types of primary liver cancer (PLC). Although ICC and HCC share similar risk factors and clinical manifestations, ICC usually bears poorer prognosis than HCC. Confidently discriminating ICC and HCC before surgery is beneficial to both treatment and prognosis. Given the lack of effective differential diagnosis biomarkers and methods, construction of models based on available clinicopathological characteristics is in need. Nomograms present a simple and efficient way to make a discrimination. A total of 2894 patients who underwent surgery for PLC were collected. Of these, 1614 patients formed the training cohort for nomogram construction, and thereafter, 1280 patients formed the validation cohort to confirm the model's performance. Histopathologically confirmed ICC was diagnosed in 401 (24.8%) and 296 (23.1%) patients in these two cohorts, respectively. A nomogram integrating six easily obtained variables (Gender, Hepatitis B surface antigen, Aspartate aminotransferase, Alpha fetoprotein, Carcinoembryonic antigen, Carbohydrate antigen 19-9) is proposed in accordance with Akaike's Information Criterion (AIC). A score of 15 was determined as the cut-off value, and the corresponding discrimination efficacy was sufficient. Additionally, patients who scored higher than 15 suffered poorer prognosis than those with lower scores, regardless of the subtype of PLC. A nomogram for clinical discrimination of ICC and HCC has been established, where a higher score indicates ICC and poor prognosis. Further application of this nomogram in multicenter investigations may confirm the practicality of this tool for future clinical use. PMID- 29473341 TI - Expression and copy number gains of the RET gene in 631 early and mid stage non small cell lung cancer cases. AB - BACKGROUND: To identify whether RET is a potential target for NSCLC treatment, we examined the status of the RET gene in 631 early and mid stage NSCLC cases from south central China. METHODS: RET expression was identified by Western blot. RET positive expression samples were verified by immunohistochemistry. RET gene mutation, copy number variation, and rearrangement were analyzed by DNA Sanger sequencing, TaqMan copy number assays, and reverse transcription-PCR. ALK and ROS1 expression levels were tested by Western blot and EGFR mutation using Sanger sequencing. RESULTS: The RET-positive rate was 2.5% (16/631). RET-positive expression was related to poorer tumor differentiation (P < 0.05). In the 16 RET positive samples, only two samples of moderately and poorly differentiated lung adenocarcinomas displayed RET rearrangement, both in RET-KIF5B fusion partners. Neither ALK nor ROS1 translocation was found. The EGFR mutation rate in RET positive samples was significantly lower than in RET-negative samples (P < 0.05). CONCLUSION: RET-positive expression in early and mid stage NSCLC cases from south central China is relatively low and is related to poorer tumor differentiation. RET gene alterations (copy number gain and rearrangement) exist in all RET positive samples. RET-positive expression is a relatively independent factor in NSCLC patients, which indicates that the RET gene may be a novel target site for personalized treatment of NSCLC. PMID- 29473342 TI - Clofarabine exerts antileukemic activity against cytarabine-resistant B-cell precursor acute lymphoblastic leukemia with low deoxycytidine kinase expression. AB - Cytosine arabinoside (Ara-C) is one of the key drugs for the treatment of acute myeloid leukemia. It is also used for consolidation therapy of acute lymphoblastic leukemia (ALL). Ara-C is a deoxyadenosine analog and is phosphorylated to form cytosine arabinoside triphosphate (Ara-CTP) as an active form. In the first step of the metabolic pathway, Ara-C is phosphorylated to Ara CMP by deoxycytidine kinase (DCK). However, the current cumulative evidence in the association of the Ara-C sensitivity in ALL appears inconclusive. We analyzed various cell lines for the possible involvement of DCK in the sensitivities of B cell precursor ALL (BCP-ALL) to Ara-C. Higher DCK expression was associated with higher Ara-C sensitivity. DCK knockout by genome editing with a CRISPR-Cas9 system in an Ara-C-sensitive-ALL cell line induced marked resistance to Ara-C, but not to vincristine and daunorubicin, indicating the involvement of DCK expression in the Ara-C sensitivity of BCP-ALL. DCK gene silencing due to the hypermethylation of a CpG island and reduced DCK activity due to a nonsynonymous variant allele were not associated with Ara-C sensitivity. Clofarabine is a second-generation deoxyadenosine analog rationally synthesized to improve stability and reduce toxicity. The IC50 of clofarabine in 79 BCP-ALL cell lines was approximately 20 times lower than that of Ara-C. In contrast to Ara-C, although the knockout of DCK induced marked resistance to clofarabine, sensitivity to clofarabine was only marginally associated with DCK gene expression level, suggesting a possible efficacy of clofarabine for BCP-ALL that shows relative Ara-C resistance due to low DCK expression. PMID- 29473344 TI - Employment benefits and job retention: evidence among patients with colorectal cancer. AB - A "health shock," that is, a large, unanticipated adverse health event, can have long-term financial implications for patients and their families. Colorectal cancer is the third most commonly diagnosed cancer among men and women and is an example of a specific health shock. We examined whether specific benefits (employer-based health insurance, paid sick leave, extended sick leave, unpaid time off, disability benefits) are associated with job retention after diagnosis and treatment of colorectal cancer. In 2011-14, we surveyed patients with Stage III colorectal cancer from two representative SEER registries. The final sample was 1301 patients (68% survey response rate). For this study, we excluded 735 respondents who were not employed and 20 with unknown employment status. The final analytic sample included 546 respondents. Job retention in the year following diagnosis was assessed, and multivariable logistic regression was used to evaluate associations between job retention and access to specific employment benefits. Employer-based health insurance (OR = 2.97; 95% CI = 1.56-6.01; P = 0.003) and paid sick leave (OR = 2.93; 95% CI = 1.23-6.98; P = 0.015) were significantly associated with job retention, after adjusting for sociodemographic, clinical, geographic, and job characteristics. PMID- 29473343 TI - Central nervous system relapse in patients over 80 years with diffuse large B cell lymphoma: an analysis of two LYSA studies. AB - CNS relapse is reported in 2-5% of diffuse large B-cell lymphoma (DLBCL) patients, dramatically decreasing overall survival (OS). Very few studies address incidence and risk factors of CNS relapse in very elderly patients, a challenging population to treat given their commonly associated comorbidities. A retrospective analysis was performed of 270 DLBCL patients >80 years treated between 2004 and 2013 in two multicentre phase II LYSA trials (LNH03-7B, LNH09 7B) evaluating the addition of rituximab or ofatumumab to mini-CHOP as front-line therapy. No patients received CNS prophylaxis. CNS relapse was evaluated according to cumulative incidence, patient characteristics, risk factors, and survival. Median age was 83 years (range: 79-95). After a median follow-up of 28.7 months, eight patients had CNS relapse (3.0%). Median time between inclusion and CNS relapse was 19.2 months (range: 3.2-32.6). Patients survived a median of 1.5 months after CNS relapse (range: 0.4-4.1). Median OS from relapse was significantly lower in CNS relapse patients (1.5 months, 95% CI: 0.4-3.5) compared to patients with non-CNS relapse (6.6 months; 95% CI: 4.6-11.9). No baseline characteristics were associated with CNS relapse. The proportion of patients with CNS disease did not differ significantly between patients with low intermediate risk according to CNS-IPI and patients with high risk (3% vs. 2.8%, P = 1.00). CNS relapse cumulative incidence in very elderly treatment-naive patients is 1.8% at 2 years and is associated with poor survival. This population had a long median time to CNS relapse. Absence of prophylaxis did not strongly impact CNS relapse incidence. PMID- 29473345 TI - CGB5 expression is independently associated with poor overall survival and recurrence-free survival in patients with advanced gastric cancer. AB - The human CGB5 gene encodes chorionic gonadotropin (hCG)beta 5, which is aberrantly expressed in trophoblastic neoplasm and in some non-trophoblastic neoplasms. Fucntional studies observed that it involved tumor initiation, growth, and metastatic outgrowth. In this study, using data from the International Cancer Genome Consortium (ICGC) and the Cancer Genome Atlas (TCGA)-stomach adenocarcinoma (STAD), we assessed the independent prognostic value of CGB5 expression in patients with primary gastric cancer (GC). Results showed that CGB5 expression was nearly not expressed in normal GC tissues. In comparison, its expression was detected in 214 of the 415 primary GC cases (51.6%) in TCGA-STAD and was associated with poor response to primary therapy and a higher risk of recurrence and death. In early stages, CGB5 expression was not a prognostic factor in terms of OS (HR: 1.448; 95% CI: 0.811-2.588, P = 0.211) or RFS (HR: 1.659; 95% CI: 0.778-3.540, P = 0.190). However, its expression was independently associated with unfavorable OS (HR: 1.719; 95% CI: 1.115-2.651, P = 0.014) and RFS (HR: 3.602; 95% CI: 1.708-7.598, P = 0.001) in advanced stages. Using deep sequencing data from TCGA-STAD, we found that CGB5 expression was not related to its genetic amplification or DNA methylation in GC. Based on these findings, we infer that CGB5 expression is common in GC patients and its expression might independently predict poor OS and RFS in advanced stages, but not in early stages of GC.

PMID- 29473346 TI - Evaluating Interaction of Cord Blood Hematopoietic Stem/Progenitor Cells with Functionally Integrated Three-Dimensional Microenvironments. AB - Despite advances in ex vivo expansion of cord blood-derived hematopoietic stem/progenitor cells (CB-HSPC), challenges still remain regarding the ability to obtain, from a single unit, sufficient numbers of cells to treat an adolescent or adult patient. We and others have shown that CB-HSPC can be expanded ex vivo in two-dimensional (2D) cultures, but the absolute percentage of the more primitive stem cells decreases with time. During development, the fetal liver is the main site of HSPC expansion. Therefore, here we investigated, in vitro, the outcome of interactions of primitive HSPC with surrogate fetal liver environments. We compared bioengineered liver constructs made from a natural three-dimensional liver-extracellular-matrix (3D-ECM) seeded with hepatoblasts, fetal liver-derived (LvSt), or bone marrow-derived stromal cells, to their respective 2D culture counterparts. We showed that the inclusion of cellular components within the 3D ECM scaffolds was necessary for maintenance of HSPC viability in culture, and that irrespective of the microenvironment used, the 3D-ECM structures led to the maintenance of a more primitive subpopulation of HSPC, as determined by flow cytometry and colony forming assays. In addition, we showed that the timing and extent of expansion depends upon the biological component used, with LvSt providing the optimal balance between preservation of primitive CB HSPC and cellular differentiation.

AB - With the advances of x-ray excitable nanophosphors, x-ray luminescence computed tomography (XLCT) has become a promising hybrid imaging modality. In particular, a cone-beam XLCT (CB-XLCT) system has demonstrated its potential in in vivo imaging with the advantage of fast imaging speed over other XLCT systems. Currently, the imaging models of most XLCT systems assume that nanophosphors emit light based on the intensity distribution of x-ray within the object, not completely reflecting the nature of the x-ray excitation process. To improve the imaging quality of CB-XLCT, an imaging model that adopts an excitation model of nanophosphors based on x-ray absorption dosage is proposed in this study. To solve the ill-posed inverse problem, a reconstruction algorithm that combines the adaptive Tikhonov regularization method with the imaging model is implemented for CB-XLCT reconstruction. Numerical simulations and phantom experiments indicate that compared with the traditional forward model based on x-ray intensity, the proposed dose-based model could improve the image quality of CB-XLCT significantly in terms of target shape, localization accuracy, and image contrast. In addition, the proposed model behaves better in distinguishing closer targets, demonstrating its advantage in improving spatial resolution. PMID- 29473349 TI - Benchtop and animal validation of a portable fluorescence microscopic imaging system for potential use in cholecystectomy. AB - We propose a portable fluorescence microscopic imaging system (PFMS) for intraoperative display of biliary structure and prevention of iatrogenic injuries during cholecystectomy. The system consists of a light source module, a camera module, and a Raspberry Pi computer with an LCD. Indocyanine green (ICG) is used as a fluorescent contrast agent for experimental validation of the system. Fluorescence intensities of the ICG aqueous solution at different concentration levels are acquired by our PFMS and compared with those of a commercial Xenogen IVIS system. We study the fluorescence detection depth by superposing different thicknesses of chicken breast on an ICG-loaded agar phantom. We verify the technical feasibility for identifying potential iatrogenic injury in cholecystectomy using a rat model in vivo. The proposed PFMS system is portable, inexpensive, and suitable for deployment in resource-limited settings. PMID- 29473350 TI - Optical coherence tomography for the diagnosis of malignant skin tumors: a meta analysis. AB - Optical coherence tomography (OCT) is an emergent imaging tool used for noninvasive diagnosis of skin diseases. The present meta-analysis was carried out to assess the accuracy of OCT for the diagnosis of skin cancer. We conducted a systematic literature search though EMBASE, Medline, PubMed, the Cochrane Library, and Web of Science database for relevant articles published up to June 6, 2017. The quality of the included studies was assessed using the QUADAS-2 tool and the Oxford Levels of Evidence Scale. Statistical analyses were conducted using the software Meta-Disc version 1.4 and STATA version 12.0. A total of 14 studies involving more than 813 patients with a total of 1958 lesions were included in our analyses. The pooled sensitivity and specificity of OCT for skin cancer diagnoses were 91.8% and 86.7%, respectively. Subgroup analysis showed that the pooled sensitivities of OCT for detecting basal cell carcinoma (BCC), squamous cell carcinoma (SCC), actinic keratosis, and malignant melanoma were 92.4%, 92.3%, 73.8%, and 81.0%, respectively. The pooled specificities were 86.9%, 99.5%, 91.5%, and 93.8%, respectively. OCT appears to be useful for the detection of BCC and SCC. It is a valuable diagnostic method when screening for early skin cancers.

AB - OBJECTIVE: To observe the effects of electroacupuncture (EA) with different frequencies based on the western conventional treatment and rehabilita tion training for stroke dysphagia. METHODS: Sixty patients with dysphagia after stroke were randomized assigned into a low frequency (2 Hz) group and a high frequency (100 Hz) group, 30 cases in each one. Basic treatment was applied in the two groups. The acupoints were Fengfu (GV 16) and Lianquan (CV 23). EA with continuous wave and tolerant intensity were connected for 30 min, once a day for 14 days. The main index was video fluoroscopic swallowing study (VFSS) to detect passing time at oral stage, pharynx delay time at pharyngeal stage, passing time at pharynx stage. The second indexes were water swallow test rating and standardized swallowing assessment (SSA). The clinical effect was evaluated. RESULTS: After treatment, the passing time at oral stage, pharynx delay time at pharyngeal stage, passing time at pharynx stage were lower than those before treatment in the two groups (all P <0.05), and the results in the low frequency group were better (all P <0.05). After treatment, the water swallow test rating improved in the two groups (both P<0.05), and that in the low frequency group was better (P<0.05). The SSA score decreased in the two groups (both P<0.05), and the improvement in the lower frequency group was superior to that in the high frequency group (P<0.05). The total effective rate in the low frequency group was 93.3% (28/30), which was better than 66.7% (20/30) in the high frequency group (P<0.05). . CONCLUSION: The effect of EA with lower frequency is better than that of EA with higher frequency for stroke dysphagia.

AB - OBJECTIVE: Based on rehabilitation training, to observe the clinical effect difference between pricking combined with cupping and western medication for elbow flexion spasticity of upper limb of stroke patients. METHODS: Sixty patients were randomly assigned by SPSS software random number generator into a comprehension group and a western medication group, 30 cases in each one. Rehabilitation was used in the two groups. Pricking and cupping were applied at the affected abdominal center of biceps brachii muscle on Tuesday and Friday continuously for 4 weeks in the comprehensive group. Baclofen was prescribed orally continuously for 4 weeks, once 10 mg and 3 times a day in the western medication group. The indexes were observed before and after 4-week treatment as well as at immediate treatment, immediately after the first treatment in the comprehension group and 24 h after treatment in the western medication group, including the affected elbow joint activity, modified Ashworth scale (MAS), simple Fugl-Meyer assessment (FMA), integrated electromyogram (IEMG) of the affected biceps brachii and triceps brachii. The clinical effects were evaluated. RESULTS: After treatment, the elbow joint activity in the two groups was improved compared with that before treatment (both P <0.05), with better result in the comprehension group (P <0.05). There was no statistical significance for MAS and FMA scores at immediate treatment between the two groups (both P >0.05). After treatment, the MAS score decreased and the FMA score increased in the two groups (both P<0.05), with better results in the comprehension group (both P <0.05). At immediate treatment and after treatment, biceps brachii IEMG decreased in the two groups (all P <0.05). The biceps brachii IEMG in the comprehension group at the immediate treatment was higher and that after treatment was lower compared with those in the western medication group (both P <0.05). The triceps brachii IEMG at immediate treatment was not statistically different from that before treatment in the comprehension group (P >0.05) and that in the western medication group decreased (P<0.05). After treatment, the triceps brachii IEMG increased in the two groups (both P <0.05), with higher IEMG in the comprehension group (P <0.05). The total effective rate was 83.3% (25/30) in the comprehensive group, which was higher than 60.0% (18/30) in the western medication group (P <0.05). . CONCLUSION: Pricking and cupping combined with rehabilitation training can reduce the IEMG of the biceps brachii muscle in patients with stroke, and improve the spasticity and motor function.

AB - OBJECTIVE: To observe the effects for vascular dementia (VD) of kidney essence deficiency among acupuncture at five mind points combined with modified kidney qi decoction, simple acupuncture at five mind points and simple modified kidney qi decoction. METHODS: A total of 180 VD patients were randomly assigned into a combination group, an acupuncture group and a herb group, 60 cases in each one. The conventional western medication and rehabilitation training were for all the patients. The modified kidney qi decoction was used in the herb group; acupuncture at Baihui (GV 20) and Sishencong (EX-HN 1) was applied in the acupuncture group; the above two methods were for the cases in the combination group. Acupuncture was used for 7 courses, twice a day, and 5 days as a course. The hasegawa dementia scale (HDS), the brief screening scale for dementia (BSSD) and the mini-mental state examination (MMSE) were applied before and after treatment. The serum superoxide dismutase (SOD), calcitonin gene-related peptide (CGRP) and lipid peroxidation (LPO) were detected before and after treatment. The effects were evaluated. RESULTS: The total effective rate of the combination group was 91.7% (55/60), which was better than 68.3% (41/60) in the herb group and 78.3% (47/60) in the acupuncture group (both P<0.05). After treatment, the scores of HDS, BSSD and MMSE were higher than those before treatment in the three groups (all P<0.05), and the scores in the combination group were superior to those in the other two groups (all P<0.05). SOD and CGRP increased and LPO decreased after treatment in the three groups (all P<0.05), and the results in the combination group were better (all P<0.05). . CONCLUSION: Acupuncture at five mind points combined with modified kidney qi decoction for VD is better than simple five mind acupuncture and simple modified kidney qi decoction.

AB - OBJECTIVE: To observe the clinical therapeutic effects on severe acute pancreatitis (SAP) treated with electroacupuncture (EA), sparse-dense wave and 2 Hz/15 Hz, at Dachangshu (BL 25) and Shangjuxu (ST 37) assisting ulinastetin and explore the effective therapeutic method for SAP. METHODS: A total of 120 patients of SAP were randomized into an observation group and a control group, 60 cases in each one. In the control group, the routine western medicine was adopted with the intravenous drip with ulinastatin. In the observation group, on the basis of the treatment as the control group, EA was applied at Dachangshu (BL 25) and Shangjuxu (ST 37). The treatment was given once every day, 20 min each time. The treatment was 2 weeks in the two groups. The recovery time of defecation, the recovery time of bowel sound, the remission time of abdominal pain and the hospitalization time were recorded in the patients of the two groups. The changes in the tumor necrosis factor alpha (TNF-alpha), interleukin-6 (IL-6) and amylase, as well as the scores in the acute physiology and chronic health evaluation II (APACHE II) were compared in the patients of the two groups before treatment, and on the 3rd, 8th and 14th days of treatment. The therapeutic effects, the cases of surgical transfer or the cases of the transfer of intensive care unit (ICU) were compared between the two groups. RESULTS: The recovery time of defecation, the recovery time of bowel sound and the remission time of abdominal pain, as well as the hospitalization time in the observation group were shorter than those in the control group (all P <0.05). The levels of TNF-alpha, IL-6 and amylase, as well as the scores of APACHE II on the 3rd, 8th and 14th days of treatment were all reduced as compared with those before treatment in the two groups (all P <0.05). The results in the observation group were lower than those in the control group (all P <0.05). The total effective rate was 95.0% (57/60) in the observation group, better than 81.7% (49/60) in the control group (P <0.05). There were 1 case of surgical transfer and 0 case in ICU transfer in the observation group, 3 cases of surgical transfer and 2 cases in ICU transfer in the control group, indicating the significant differences between the two groups (both P <0.05). . CONCLUSION: EA at Dachangshu (BL 25) and Shangjuxu (ST 37) displays the satisfactory accessory therapeutic effects on SAP treated with ulinastatin.

AB - OBJECTIVE: To evaluate the effect and clinical value of auricular point sticking for the diagnosis and treatment of vasospasm and vagus reflex during radial artery puncture, including radial artery spasm (RAS) and coronary artery spasm (CAS). METHODS: A total of 480 patients were randomized into an observation group (224 cases) and a control group (256 cases). Percutaneous coronary intervention and usual care in perioperative period were used in the control group. Auricular point sticking was began to apply 12 h before percutaneous coronary intervention in the observation group at Jiaogan (AH6a), Shenmen (TF4), Pizhixia (AT4), Neifenmi (CO18), Xin (CO15), Shen (CO10), Shenshangxian (TG2p), 1 min a time every point, once every 2 h, 12 h before and after operation. The incidences of vasospasm and vagus reflex during piercing process were compared, and the usage ratios of vasoactive agent were recorded, including glyceryl trinitrate, dopamine and atropine injections. RESULTS: The incidence of angiospasm was 4.9% (11/224) in the observation group, which was lower than 13.3% (34/256) in the control group (P<0.01). The incidence of vagal reflex of the observation group was 7.1% (16/224), which was lower than 19.5% (50/256) of the control group (P<0.01). The usage ratios of glyceryl trinitrate, atropine and dopamine injections were 3.6% (8/224), 7.1% (16/224), 6.3% (14/224) respectively in the observation group, which were lower than 14.8% (38/256), 15.6% (40/256), 15.2% (39/256) in the control group (all P<0.01). . CONCLUSION: Auricular point sticking achieves effect for the diagnosis and treatment of vasospasm and vagus reflex during radial artery puncture.

METHODS: Ninety children of cerebral palsy were assigned into 9 groups by orthogonal design, 10 cases in each one. The acupoints were bilateral excitable area, foot motor sensory area, speech two area, speech three area, balance area, and intelligent nine acupoints, including Shenting (GV 24), Sishencong (EX-HN 1), and bilateral Benshen (GB 13) and Touwei (ST 8). EA was applied at bilateral excitable area and speech three area. We designed an orthogonal experiment with four factors and three levels. We studied wave (sparse wave of 2 Hz, density wave of 100 Hz, sparse and density wave of 2 Hz /100 Hz), intensity (1 mA, 2 mA, intensity based on tolerance), time (10 min, 20 min, 30 min), frequency (once a day, once every other day, twice a week). The Gesell developmental scale was used to evaluate the developmental quotient (DQ); and gross motor function measure (GMFM), motor function before and after treatment. RESULTS: The optimal parameters for DQ and GMFM were 2 Hz/100 Hz, 20 min, once every other day. . CONCLUSION: The optimal parameters for cerebral palsy may be 2 Hz/100 Hz, 20 min, once every other day.

AB - OBJECTIVE: To compare the differences in the clinical therapeutic effects on juvenile myopia between Zheng's stunt needling technique and traditional even needling technique. METHODS: A total of 166 cases of mild juvenile myopia (diopter <-3.00D) were randomized into an observation group (Zheng's stunt needling technique) and a control group (traditional even needling technique), 83 cases in each one (166 affected eyes). Taiyang (EX-HN 5), Fengchi (GB 20), Cuanzhu (BL 2), Hegu (LI 4) and Guangming (GB 37) were used in the two groups. In the observation group, the erlongxizhu needling technique was adopted at Taiyang (EX-HN 5), the guoyanre needling technique at Fengchi (GB 20) and xiquedengmei needling technique at Cuanzhu (BL 2). The traditional needling technique was used at Hegu (LI 4) and Guangming (GB 37). In the control group, traditional even needling technique was applied at all the acupoints. The treatment was given once every day, continuously for 6 times as one course. There was 1 day at interval. After treatment for 4 courses, the changes in visual acuity, diopter and axial length were observed before and after treatment. The therapeutic effects were evaluated. RESULTS: After treatment, the visual acuity of the naked eyes, and diopter were remarkably improved in the patients of the two groups (all P <0.05). The improvements in the observation group were better than those in the control group (both P <0.05). The axial length did not change in the two groups (both P>0.05). The total effective rate was 78.3% (130/166) in the observation group, which was better than 57.8% (96/166) in the control group (P <0.05). . CONCLUSION: Zheng's stunt needling technique effectively improves the vision, rectifies the refractive error and delays the progression of myopia. The therapeutic effects of it are better than traditional even needling technique. PMID- 29473358 TI - [Guiding-qi acupuncture for dry eye syndrome]. AB - OBJECTIVE: To observe the clinical efficacy differences between different needling methods for dry eye syndrome. METHODS: Sixty patients of dry eye syndrome were randomly divided into an observation group and a control group, 30 cases (60 eyes) in each group. Shangjingming (Extra), Xiajingming (Extra), Tongziliao (GB 1), Cuanzhu (BL 2), Fengchi (GB 20), Hegu (LI 4), Sanyinjiao (SP 6), Taixi (KI 3) and Taichong (LR 3) were selected in the two groups. The control group was treated with conventional acupuncture, while the observation group was treated with guiding-qi acupuncture. Electroacupuncture (EA) was used at bilateral Tongziliao (GB1) and Cuanzhu (BL 2), 30 min per treatment. The treatment was given three times per week. Totally 1-month treatment (12 treatments) was given. The eye symptom score, breakup time of tear film (BUT), Schirmer I test (SIT) and visual analogue scale (VAS) score were compared before and after treatment in the two groups. The clinical efficacy was compared between the two groups. RESULTS: Compared before treatment, the eye symptom score, BUT, SIT and VAS score were improved after treatment in the two groups (all P <0.001); the improvements of eye symptom score and SIT in the observation group were superior to those in the control group (both P<0.05). The differences of BUT and VSA score between the two groups were not significant (both P>0.05). The total effective rate was 86.7% (52/60) in the observation group, which was superior to 73.3% (44/60) in the control group (P<0.05). . CONCLUSION: The conventional EA and guiding-qi acupuncture combined with EA are both effective for dry eye syndrome, and the efficacy of guiding-qi acupuncture combined with EA is superior to that of conventional EA. PMID- 29473359 TI - [Comparison of the effects of the intervention with electric thermal bian stone and air suction cup on blood perfusion at meridian points]. AB - OBJECTIVE: To observe the impacts of the intervention with electric thermal bian stone and air suction cup on blood perfusion (BP) at meridian points and explore the approach of accurate measurement and regulation of meridian qi and blood balance in "precise acupuncture". METHODS: The laser Doppler line scanner (LDLS) was used to measure BP at bilateral yuan-primary points at the pericardium meridian, the triple energizer meridian, the gallbladder meridian and the liver meridian (small cycle of jueyin to shaoyang meridians) at 31 healthy receptors. The bias ratio of blood perfusion (BPBR) deviated to the reference value was calculated. The electric thermal bian stone and air suction cup were used in the intervention at the he-sea points of the affected meridians in which BPBR was relatively higher at the yuan-primary points. The electric thermal bian stone therapy was used when BPBR was less than -30% and the air suction cupping therapy was used when BPBR was higher than 30%. BP was measured twice before intervention and it was measured separately at the moment after intervention and in 20 min after intervention. The means of BP before and after intervention and the change ratio of blood perfusion (BPCR) before intervention, at the moment after intervention and 20 min after intervention were calculated. RESULTS: 1. After the intervention of electric thermal bian stone, BP mean was increased from (103.51+/ 41.21) PU to (121.97+/-56.22) PU (P<0.05). Before intervention, at the moment after intervention and 20 min after intervention, separately, BRCR were (-0.58+/ 16.18)%, (23.58+/-48.85) % and (25.62+/-65.89) %. BPCR at the moment after treatment was increased significantly as compared with that before intervention (P<0.01). The difference was not significant in 20 min after intervention and before intervention (P>0.05), but the change ratio was highly remained. 2. After intervention with air suction cup, BP mean was reduced from (194.83+/-81.14) PU to (173.88+/-88.26) PU. Before intervention, at the moment after intervention and 20 min after intervention, separately, BPCR were (7.62+/-30.49)%, (-12.12+/ 18.20)% and (-14.35+/-21.25)%. BPCR at the moment after intervention and in 20 min after intervention were significantly different from that before intervention (both P<0.01). . CONCLUSION: The electric thermal bian stone increases the blood flow at the yuan-primary point when acting on the he-sea point of the same meridian. The influence of the air suction cup is opposite. PMID- 29473360 TI - [Exploration of the meridian differentiation law in polycystic ovarian syndrome of hirsutism based on data mining technology]. AB - OBJECTIVE: To analyze the distribution characteristics of hirsutism and the law of meridian differentiation in polycystic ovarian syndrome (PCOS). METHODS: For the patients of PCOS, the modified Ferriman-Gallwey score (mF-G score) was adopted to evaluate the hirsutism distribution. The clementine data mining software was used to analyze the distribution region of hirsutism and the correlation with meridian. RESULTS: A total of 141 patients of PCOS participated in the study. The most common regions of hirsutism were in the upper lip (50.35%) and the lower abdomen (34.04%). The higher frequencies of hirsutism at two regions were at the upper lip and lower abdomen (24.82%), the upper lip and chest (12.06%) and the upper lip and thigh (11.35%). In the analysis on the correlation of the upper lip, lower abdomen and chest with other regions, hirsutism was more common in the nearby regions. In reference to the running course of meridian, the frequencies of hirsutism from high to low were the conception vessel (63.12%), the thoroughfare vessel (61.70%), the liver meridian of foot-jueyin (58.16%) and the stomach meridian of foot-yangming (57.45%). According to Miraculous Pivot: Yinyang Twenty-Five Persons, the high incidence of hirsutism (59.57%) resulted from the change of qi and blood in yangming meridian. . CONCLUSION: Blood plays the important role in the growth of body hair. Regarding the yinyang attribution, the incidence of hirsutism at the yin regions is higher than the yang regions. The occurrence of hirsutism is closely related to qi and blood changes in meridians. The conception vessel, the thoroughfare vessel, the liver meridian of foot-jueyin and yangming meridian act highly on the disease. PMID- 29473361 TI - [Effects of electroacupuncture on the expression of adenosine receptors in the heart tissue of myocardial ischemia rats]. AB - OBJECTIVE: To explore the impact of electroacupuncture (EA) on the protein expression of adenosine receptors in the heart of the rats with myocardial ischemia (MI). METHODS: Thirty healthy male SD rats were divided randomly into a control group (n=6), a model group (n=12) and an EA group (n=12). We ligated the left anterior descending artery (LAD) for MI model in the model group and EA group, and exposed the heart after opening the chest without ligation in the control group. EA, 2 Hz /15 Hz and 1.5-2 mA, was applied at bilateral"Neiguan"(PC 6) in the EA group for 20 min, once a day for continuous 5 days. No intervention except grabbing and fixation was used in the control group and model group. We applied 2% TTC staining to observe the infarct size of myocardium, colorimetry to analyze serum lactic dehydrogenase (LDH), creatine kinase (CK), creatine kinase isoenzyme (CK-MB), radio-immunity assessment to detect cardiac troponin T (cTnT), Western blot to evaluate the adenosine A1 receptor (A1AR), A2aAR, A2bAR and A3AR. RESULTS: After treatment, myocardial infarction of (27.56+/-3.24)% was obvious in the model group; the myocardial infarction in the EA group was (21.04+/-3.61)%, with statistical significance (P<0.05). The expressions of serum LDH, CK, CK-MB and cTnT levels in the model group increased compared with those in the control group (all P<0.01), and the expressions of LDH, CK, CK-MB and cTnT levels in the EA group decreased compared with those in the model group (P<0.05,P<0.01). The A1AR expression in the model group was not different from that in the control group (P>0.05), and A2aAR,A2bAR,A3AR expressions decreased (P<0.05, P<0.01). A2aAR and A2bAR expressions in the EA group increased compared with those in the model group (both P<0.01), and there was no statistical significance between A1AR and A3AR expressions (both P>0.05). . CONCLUSION: EA may achieve cardioprotective effect by regulating the expressions of A2aAR and A2bAR in myocardial tissue, which induce the corresponding signal cascade for reducing myocardial infarction area. PMID- 29473362 TI - [Effects of electroacupuncture on expression of CD36 in peritoneal macrophages of rabbits with atherosclerosis]. AB - OBJECTIVE: To observe the effect of electroacupuncture (EA) on the expressions of CD36 gene and protein in peritoneal macrophages of atherosclerotic rabbits, and to explore the mechanism of acupuncture regulation of atherosclerosis. METHODS: A total of 26 male New Zealand rabbits were randomly divided into a blank group (7 rabbits) and a model group (19 rabbits). The rabbits in the blank group were fed with common feedstuff, and those in the model group were applied with high fat diet and arteria carotis communis bullon injury. One rabbit was sacrificed after 8 weeks to observe the morphological changes of carotid atherosclerotic plaques by HE staining to verify model establishment separately in the blank group and model group. The model rabbits were randomized into a control group, an EA group and a western medication group, 6 rabbits in each one. Common feedstuff was used in the blank group and high fat feed in the other groups. No intervention except grabbing and fixation as the EA group was in the blank group and control group. Rabbits in the EA group were treated with acupuncture at bilateral "Neiguan" (PC 6), "Zusanli" (ST 36), "Guanyuan" (CV 4), and EA with sparse-dense wave was connected at bilateral "Neiguan" (PC 6) and "Zusanli" (ST 36) for 20 min, 4 Hz/20 Hz and 1 mA. 20 mL suspension of 1mg/kg/d atorvastatin calcium tablets were prescribed by intragastric administration in the western medication group for 4 courses, 6 d as one course with 1 d between two courses, once a day. The expression of CD36 protein in peritoneal macrophages was detected by Western blot. Reverse transcription (RT) of RNA and polymerase chain reaction (PCR) of cDNA were used to detect the expression of CD36 mRNA in peritoneal macrophages. RESULTS: In the blank group, the vascular wall thickness was uniform and the endothelium was intact. There was no accumulation of foam cells and atherosclerotic plaques. In the model group, the intima of the artery obviously thickened; the intima was damaged; the atherosclerotic plaque and inflammatory cell infiltration were found in the intima, and the foam cells were seen. After treatment, the expressions of CD36 protein and CD36 mRNA in the control group, EA group and western medication group were higher than those in the blank group (all P<0.01). Those in the EA group and western medication group were lower than the expressions in the control group (all P<0.01). There was no statistical significance for the expressions of CD36 protein and CD36 mRNA between the EA group and the western medication group (both P>0.05). . CONCLUSION: EA can reduce the expressions of CD36 protein and CD36 mRNA in peritoneal macrophages of atherosclerotic rabbits, which may be one of the mechanisms of EA treatment of atherosclerosis. PMID- 29473363 TI - [Analysis on standardization of patient posture for acupuncture treatment]. AB - The standardization of patient posture for acupuncture treatment was discussed. According to the opinions in Neijing (Inner Canon of Huangdi), combined with the clinical practice of acupuncture, it was believed that the patient posture for acupuncture treatment should be standardized based on Neijing. The standardized patient posture was the foundation of acupuncture, the need of blood flow and requirement of acupuncture technique. The combination of three elements was beneficial for the traveling of spirit-qi through meridian-acupoint, which could regulate balance of yin and yang to treat disease. In addition, the principles and methods of standardization of patient posture was proposed, and the important clinical significance of standardization of patient posture for acupuncture treatment was highlighted. PMID- 29473364 TI - [Discussion on several contents of textbook Acupuncture and Moxibustion (New Century 4th Edition)]. AB - The textbook Acupuncture and Moxibustion (New Century 4th Edition) was published by China Press of Traditional Chinese Medicine in August of 2016. The author proposed several discussions in the textbook. The information, including the issue date of China national standard Standardized Manipulations of Acupuncture and Moxibustion, the number of foreign countries where China medical teams were assigned, and the number of acupuncture indications recommended by WHO, was not accurate. The content, including several methods of acupoint location, specification of filiform needles, rotating angle of needle, disinfection of needles and skin, locations and indications of scalp acupuncture, etc. should be corrected. Besides, the writing of textbooks should follow national or industry standards. PMID- 29473365 TI - [The textual research of "body cun"]. AB - Although the concept of "body cun" was proposed in Neijing (Inner Canon of Huangdi), it was matured in Qianjin Yaofang (Invaluable Prescriptions for Ready Reference) in Tang Dynasty, so it was believed by the majority of physicians this term was firstly proposed in Qianjin Yaofang. In this study, the literature regarding "body cun" was reviewed, and it was believed the term was originated from Chongguangbuzheng Huangdineijingsuwen, when WANG bing noted Suwen (The Plain Questions). The connotation of the "body cun" included multiple meanings, such as bone cun, finger cun and so on, and the points of view were different in different periods, different doctors or scholars. From the respective explanation of bone cun and finger cun to the combination use in Ming Dynasty and Qing Dynasty, the extension of the term was embodied. After the establishment of term' s connotation and extension, the translation of the term was accurate and clear.

AB - There are two systems as the red channel system and the white channel system carved or painted on the wooden figurine of Laoguanshan of Benque school. The two systems are horizontally staggered each other without overlapped. The red channel system, similar to Shuangbaoshan wooden figurine, have channels, but without points. For the white channel system, the running courses of channels result from the sensation distributions of the points after optional stimulation. The Laoguanshan wooden figurine focuses on the illustration of the white channel system, named as white channel figurine. Compared with the Shuangbaoshan red channel figurine, together with examples, such as the running course of the white channel related to the meridian of heart-transfer-point, the white channel related to the belt vessel linking to lung-transfer-point, stomach-transfer-point and kidney-transfer-point, as well as the corresponding photographs. It is indicated that the Laoguanshan white channel figurine is a training aid for testing the sensation marching along channel (SMC) caused by transfer-point stimulation. The white channel system is a flexible way of channel. The study aims to observe the QI/SMC reaching the affected area and contributes to clinical practice. This discovery is not related to the "intermediate link theory" in the Yellow Emperor meridian system. PMID- 29473367 TI - [The relationship between acupuncture-moxibustion theory of DOU Hanqing and Neo- Confucianism]. AB - For the construction factors of acupuncture-moxibustion theory of DOU Hanqing, a doctor in Jin-Yuan Dynasty, we studied his life, acupuncture-moxibustion theory and culture background in the History of Medicine and Philosophy of Science & Technology. It was found that the major source of DOU Hanqing' s Confucianism was the CHENG-ZHU Neo-Confucianism. The data show that Neo-Confucianism played an important role in the enrichment of his human nature, spirit, moral cultivation and political talent, making him a scholar in the Jin-Yuan dynasty, also shaping his medical ethics, medical skill and acupuncture-moxibustion theory. The inheritance, development and application of CHENG-ZHU Neo-Confucianism provided the most fundamental thinking, research methods and patterns for DOU Hanqing to interpret the acupuncture classics, summarize his teachers' experience and develop his theoretical system. DOU Hanqing' s acupuncture-moxibustion practice and theory reached a new level, because he took acupuncture-moxibustion as one of the knowledge investigation and attainment of CHENG-ZHU Neo-Confucianism.

AB - OBJECTIVE: To summarize the 2491 acupuncture inpatient consultations in Qilu Hospital of Shandong University during 2014, and analyze the application of acupuncture in comprehensive hospital, hoping to provide direction and methods for clinical practice and scientific research of acupuncture. METHODS: The consultation record and hospitalization information during 2014 in Department of Acupuncture-Moxibustion and Tuina, Qilu Hospital of Shandong University, were collected and summarized through Inpatient Information Management System. The distribution of consultation discipline and disease were analyzed. RESULTS: Among all the consultations, 15 second-class disciplines were involved, and the number of neurology and surgery was 1399, accounting for 59.00% of all consultation. 111 types of diseases were found in consultation, mainly postoperative complications, cerebrovascular disease and arthropathy. The primary disease of consultations involved all the systems, mainly nervous system disease, musculoskeletal system disease, connective tissue diseases and genitourinary system diseases, accounting for 73.89% of all consultations. . CONCLUSION: Acupuncture is closely related with clinical disciplines of neurology and surgery. The cooperation between acupuncture and pediatrics and oncology should be strengthened. Acupuncture has an advantage over treating postoperative complications and neuromuscular diseases. PMID- 29473370 TI - [The design and application of a moxibustion instrument with less harmful smoke and direction adjustment]. AB - The design of a clip-on moxibustion instrument which could adjust the directions and absorb harmful granules of moxa smoke was introduced in this paper. It was designed to solve the problems in home health care and clinical treatment, such as the inconvenience of adjustment of moxibustion directions and temperature, more dust and granules of moxa smoke and inconvenience of moxibustion placement. The main part of moxibustion instrument was made up of moxibustion box, bracket and base clamp. The moxibustion box could fix moxa stick and absorb smoke granules; the bracket could be twisted to adjust the direction of moxibustion box; the base clamp was aimed to fix moxibustion box on the edge of the object to save space. This moxibustion instrument could be used for various indications of moxibustion, especially in the joints or body parts with less muscles; and it can significantly enhance the pertinence and safety of moxibustion, and reduce the labor intensity. This moxibustion instrument is original and unique, simple and reasonable, easy to operate, with low cost and good effect, which will increase new vitality for the popularization and development of moxibustion. PMID- 29473371 TI - [Research progress of fire needling for chronic gastritis]. AB - To explore the efficacy and mechanism of fire needling for chronic gastritis, "fire needling" and "chronic gastritis" were selected as keywords to collect literature in PubMed, CNKI database and WanFang database. The clinical and experiment literature regarding fire needling for chronic gastritis was analyzed to make a comprehensive discussion on the efficacy and action mechanism of fire needling for chronic gastritis. The results indicated the efficacy of fire needling for chronic gastritis was superior to that of medication or filiform needle. The combination of fire needling and medication, acupoint injection and filiform needle could further improve the therapeutic effect for chronic gastritis. From the perspectives of TCM and western medicine, the action mechanism of fire needling for chronic gastritis was explored, and it was believed the fire-needle therapy has the effects of removing and nourishing, which conformed to the clinical syndromes of chronic gastritis. The fire needle could affect the prognosis by regulating the central nerve system, improving local blood circulation, regulating immune inflammation and regulating gastrointestinal hormones. PMID- 29473372 TI - Risk factors for benign prostatic enlargement: The role of lifestyle habits at younger age. The #Controllati2017 initiative study group. AB - OBJECTIVE: The risk factors for benign prostatic enlargement (BPE) are not well understood and particularly few data are available from Italian population. MATERIALS AND METHODS: This was an observational cross sectional study aimed to examine the association between several risk factors and BPE. During the "#Controllati2017" initiative, men aged 18 years or more were invited to attend participating urologic centers for a free of charge visit for counseling about urologic or andrologic conditions. Each participating man underwent a physical examination including digital rectal examination (DRE). Further he was asked about his medical history, urologic symptoms, sexual activity and related problems. Diagnosis of BPE was made by the urologist after DRE. RESULTS: Out of the 1902 [mean age 54 years (SD 12, range 18-92)] considered men, a total of 603 subjects (31.7%) had diagnosis of BPE. The diagnosis of BPE increased from 9.3% in men aged < = 50 years, to 34.1% in those aged 51-60 years and to 58.7% among men aged > 60 years. A history of hypertension, diabetes, heart diseases, hypercholesterolemia and hypertriglyceridemia were all significantly associated with an increased risk of BPE in the total series and, although not always in a statistically significant way, in strata of age. Physical activity (PA) was significantly associated with a decreased risk of BPE. We have further analyzed the risk of BPE in men with one or more of the identified risk factors (i.e. hypertension, diabetes, heart disease, hypercholesterolemia, hypertriglyceridemia and low PA): the risk of BPE increased with number of risk factors reported by the subjects. The estimated risk were higher among younger men. CONCLUSION: In our study a history of hypertension, diabetes, heart disease, hypercholesterolemia and hypertriglyceridemia increased the risk and physical activity lowered the risk of BPE. This risk profile was observed also in men aged < 50 years. PMID- 29473373 TI - Medical management in locally advanced and metastatic prostate cancer: Does changes in treatment policy have any specific effect on PSA levels? AB - OBJECTIVE: Androgen deprivation therapy (ADT) is commonly used as a first-line treatment for locally advanced and metastatic prostatic cancer (Pca). There is no consensus about which alternative treatment should be used after the failure of initial ADT. We aimed to investigate the effect of changes in treatment on PSA and testosterone levels. MATERIAL AND METHODS: A total of 120 patients with an established diagnosis of either locally advanced or metastatic Pca in two different centers. Depending on the type of medical and/or surgical management protocol planned at initial presentation, all cases were divided into three main groups as follows. Group 1 (n: 80) included the patients who underwent medical management during whole follow-up period in whom the initial management protocol was later on switched to another medical treatment with different agents, Group 2 (n: 20) included patients who were initially treated with a medical management protocol and switched to surgical castration during follow-up evaluation and lastly Group 3 (n: 20) included the patients undergoing treated surgical castration as initial treatment modality without any further medical management protocol. RESULTS: Evaluation of our data did clearly demonstrate a statistically significant difference between the initial and final PSA as well as testosterone levels in Group 1 cases. Mean PSA and testosterone levels increased significantly in these cases despite a change in hormonal therapy by using another agent for androgen deprivation. Cases in Group 2 and 3 cases did not show any statistically significant difference with respect to the mean PSA as well as testosterone values during the same follow-up period. CONCLUSIONS: Our data clearly indicated that in case of a biochemical progression, switching into another alternative medical treatment was not effective enough in limiting the rising PSA levels in a statistically significant manner when compared with the approaches of switching to surgical castration after initial medical treatment or continuing with regular and close follow-up after initial surgical castration alone. PMID- 29473374 TI - The association between prostatitis and prostate cancer. Systematic review and meta-analysis. AB - OBJECTIVE: The main outcome of this review was the association between a history of clinical chronic prostatitis (NIH category II or III) and a histologically confirmed diagnosis of prostate cancer. MATERIALS AND METHODS: Crude odds ratios and 95% confidence intervals (CI) were calculated to analyze dichotomous data. For analysis of pooled data we adopted a random-effects model and the inverse variance weighing method. Heterogeneity was assessed by calculating the I2 value. RESULTS: Out of 2794 screened records, we retrieved 16 full-text articles written in English, reporting the data of 15 case-control studies, involving 422.943 patients. Pooled analysis resulted in a significant crude odds ratio of 1.83 (95% CI: 1.43 to 2.35; P < 0.00001). The total set of data showed considerable heterogeneity (I2 = 91%). Both the Egger's test and the Begg's test for funnel plot asymmetry did not reach statistical significance. The 'trim and fill' method applied to the funnel plot imputed 3 missing studies and the resulting adjusted estimate of the odds ratio was 2.12 (95% CI: 1.38 to 3.22). According to GRADE criteria, the overall quality of the meta-analysis data is low, mainly due to the presence of bias, confounders and extreme effect size outliers. Five among the included studies reported data assessed in 8015 African-American subjects. Pooled analysis resulted in a non-significant crude odds ratio of 1.59 (95% CI: 0.71 to 3.57; P = 0.26), and considerable heterogeneity (I2 = 90%). CONCLUSIONS: Meta analysis of 15 case-control studies shows that a history of clinical chronic prostatitis can significantly increase the odds for prostate cancer in the general population, whereas such association in African-American individuals remains uncertain. PMID- 29473375 TI - Evaluation of the complications in laparoscopic retroperitoneal radical nephrectomy; An experience of high volume centre. AB - OBJECTIVES: To provide a standardised report of complications after retroperitoneal laparoscopic radical nephrectomy (rLRN) in a high-volume centre using Clavien-Dindo classification. MATERIALS AND METHODS: We analysed records maintained in a prospective database of 330 consecutive patients that underwent rLRN between March 1995 and September 2016. All complications were graded according to the modified Clavien-Dindo classification. Three generations of surgeons were defined and the learning curve in rLRN was evaluated by comparing the first 100 cases (Group A) performed by firstgeneration surgeons with the last 100 cases (Group B) by thirdgeneration surgeons. RESULTS: The mean age of our cohort was 66 +/- 11.9 years. The overall complication rate was 19.7%. The majority of complications (12.7%) were Clavien 1 (5.1%) and Clavien 2 (7.6%) and did not require any interventions; blood transfusion was the most frequently encountered intervention (4.8%). Half of which were because of major intraoperative bleeding. Mortality rate was 0.9%. We found a trend towards lower complication rate in group B (19%) compared to group A (23%); this was mainly because of the reduction in the incidence of Clavien 1 and 2 complications. The pathological stage varied significantly in the two groups while the rate of negative surgical margins was comparable. CONCLUSIONS: rLRN is a safe procedure with an acceptable rate of complications. The learning curve was shorter for the thirdgeneration surgeons (group B); although these surgeons operated on a significantly higher number of patients with more advanced diseases. The Clavien Dindo classification is suitable for assessing rLRN complications. Adopting this standardised system can help in the evaluation and comparison of surgical quality of LRN series. PMID- 29473376 TI - Can re-cTURBT be useful in pT1HG disease as a risk indicator of recurrence and progression? A single centre experience. AB - INTRODUCTION: Understaging after initial transurethral resection is common in patients with high-risk non muscle infiltrating bladder cancer (NMIBC) and can delay accurate diagnosis and definitive treatment. The rate of upstaging from T1 to T2 disease after repeated transurethral resection ranges from 0 to 28%, although the rate of upstaging may be even higher up to 49% when muscularis propria is absent in the first specimen. A restaging classic transurethral resection of bladder tumour (re-cTURBT) is the better predictor of early stage progression. According to some reports, the rate of positivity for tumor in re cTURBT performed within eight weeks after initial cTURBT was as high as 18-77%, and in about 40% of the patients a change in tumor stage was reported. We aimed to investigate, in high risk group, the presence of residual tumor following white light classical transurethral resection of bladder tumor (WLre-cTURBT) and the different recurrence and progression rate between patients with persistent or negative (pT0) oncological disease after WLre-cTURBT. MATERIALS AND METHODS: A cohort of 285 patients presenting with primitive bladder cancer underwent to WLcTURBT from January 2011 to December 2015; out of them 92 (32.28%) were T1HG. In according to EAU guidelines 2011, after 4-6 weeks all HG bladder cancer patients underwent a WL recTURBT . All patients were submitted to a subsequent followup including cystoscopy every 3 months with multiple biopsies, randomly and in the previous zone of resection; urinary citology on 3 specimens and kidney/bladder ultrasound every 6 months. The average follow-up was 48 months. RESULTS: Following WLre-cTURBT we observed a persistent disease in 18 (15.2%) patients: 14 (77.7%) with a HG-NMIBC and 4 (22.2%) with a high grade (HG) muscle invasive bladder cancer (pT2HG). After follow up of all 92 patients according to the guidelines EAU, we observed recurrence in 36/92 (39.1%) and progression in 14/92 (15.2%). Of 14 NMIBC with persistent disease, 10 patients (71.4%) showed recurrence: 4 patients (40%) were pT1HG with concomitant carcinoma in situ (CIS), 3 patients (30%) multifocal pTaHG, 2 (20%) patients CIS and one patient (10%) a muscle invasive neoplasm (pT2HG). Instead of the group of 48 patients pT0 following WL recTURBT, we observed recurrence in 26 patients (54.1%) and in two patients (4.1%) progressions, who presented after 3 months in association with CIS. The remaining 22 patients (45.9%) with initial pT1HG are still progression free. Multivariate analysis showed that the most important variable of early progression were persistent neoplasm and histopathological findings at WLre cTURBt (p = 0.01), followed by the Summary No conflict of interest declared. INTRODUCTION Bladder cancer is a common genito-urinary malignancy, with transitional cell carcinoma comprising nearly 90% of all primary bladder tumours. At the first diagnosis 70% to 80% of urothelial tumours are confined to the epithelium, the remainder is characterized by muscle invasion. A significant number of patients with high risk non-muscle invasive bladder tumours (HG-NMIBT) treated with white light classic transurethral resection of bladder tumours (WLcTURBT) and intravesical BCG will progress to invasive disease (1-3). Progression to muscle invasion (pT2) mandates immediate radical cystectomy (4). WLcTURBT is the standard initial therapy for NMIBT, but the high percentage of recurrence after surgery is still an unresolved problem (5). High grade pT1 bladder neoplasm (pT1HG) really represents a therapeutic challenge due to the high risk of progression (about 15-30%) to muscle-invasive disease, usually within 5 years (6). However, no consensus exists regarding the treatment of patients with recurrent bladder tumours that invade the lamina propria (pT1) (7 9). Recent studies suggested that the first cTURBT may be incomplete in a significant number of cases (10). Understaging at the time of the initial transurethral resection is common for patients with high-risk NMIBC and can delay accurate diagnosis and definitive treatment. It is therefore recommended for patients with high-risk disease and in those with large or multiple tumors or when the initial transurethral resection is incomplete, to repeat WLre-cTURBT within 2-6 DOI: 10.4081/aiua.2017.4.272 result of the first cystoscopy (p = 0.002) and presence of CIS (p = 0.02). DISCUSSION: Following WLre-cTURBt in HG NMIBC patients we identified in 15% of cases a persistent disease with a 4.3% of MIBC. In the high risk persistent bladder neoplasms group we observed recurrent and progression rate higher than in T0 bladder tumours group (Delta = + 17.3% and = Delta + 62.5%, p < 0.05.

AB - PURPOSE: Firstly, we aimed to investigate the correlation among dynamic contrasted magnetic resonance (MR) images, diffusion-weighted MR images, and apparent diffusion coefficent (ADC) values in patients with prostate cancer. Secondly, we aimed to investigate the roles of these variables on clinical risk classification and the biological behavior of the prostate cancer. METHODS: A total of sixty with prostatic adenocarcinoma patients diagnosed between January 2011 and May 2013 were retrospectively included in the study. Risk classification of patients were evaluated as low-risk (Group 1) (n = 20) (Stage T1c-T2a, PSA < 10 ng/ml, Gleason Score < 7), moderate-risk (Group 2) (n = 18) (Stage T1b-T2c, PSA = 10-20 ng/ml, Gleason Score = 7) and high-risk (Group 3) (n = 22) (Stage > T3a, PSA > 20 ng/ml, Gleason Score > 7). Diffusion-weighted MR images, dynamic contrasted MR images, and ADC values of the prostates were correlated. RESULTS: ADC values of the cases in Group 3 were lower than those of the other groups (p < 0.001). ADC values of the areas without malignancy did not differ significantly between groups (p > 0.05). Biological activity of the tumor tissue was determined by GS, while a negative correlation was observed between GSs and ADC values of the patients, (p < 0.001). CONCLUSION: In tumors with higher Gleason scores, lower ADC values were obtained. These measured values can play a role in the noninvasive determination of the cellularity of the tumoral mass. PMID- 29473378 TI - Ureteroscopy in pregnant women with complicated colic pain: Is there any risk of premature labor? AB - OBJECTIVE: Clinical presentation of ureteral stones during pregnancy is generally with renal colic pain. The aim of this study is to present our experience in the management of renal colic during pregnancy in emergency settings. MATERIALS AND METHODS: 208 pregnant patients who presented to emergency department with renal colic pain and underwent ureteroscopy (URS) due to failed conservative therapy were enrolled in the study. Urinary tract stones were diagnosed either with ultrasound (US) examination or during URS. Laser lithotripsy and double J (DJ) stent placement were routinely done in all patients with ureteral stones. The incidence of infective complications and premature uterine contractions (PUC) due to URS were compared. RESULTS: No stone was identified in 36.1% (n = 75) of patients with using US and diagnostic URS. Of the remaining 133 patients, 30 (22.6%) had no stone at US but stones were diagnosed during diagnostic URS. The type of anesthesia had no significant effect on PUC. An increased risk of sepsis and PUC was found in patients with fever at the initial presentation. Interestingly, PUC was more frequent in patients with lower serum magnesium levels. There was a significant correlation with time delay until the intervention and the risk of urosepsis and PUC, individually. CONCLUSIONS: Ureteroscopy is a safe option for evaluation of pregnant patients with unresolved renal colic. According to the current findings, timing of the operation is the most important factor affecting the septic risks and abortion threat. Surgical intervention with URS must be planned as soon as possible. PMID- 29473379 TI - A rare cause of acute post renal failure: Retroperitoneal fibrosis. AB - Retroperitoneal fibrosis is an inflammatory process which may cause acute renal failure. In patients who admitted to emergency services with obstructive uropathy, retroperitoneal fibrosis should be considered in the differential diagnosis. We present our ten cases who admitted to emergency department with obstructive acute renal failure related to retroperitoneal fibrosis. PMID- 29473380 TI - Longitudinal prospective observational type study about determinants of renal resistive index variations in chronic renal failure patients treated with conventional medical and dietetic therapy. AB - OBJECTIVE: This longitudinal prospective observational type study was conceived with the aim to examine the impact on renal resistive index (RRI) of the variables that we can manipulate with therapeutic and or dietetic interventions in a chronic kidney disease population in order to known which of these variables was statistically related to changes in RRI and therefore could become the object of the greatest therapeutic effort. MATERIAL AND METHODS: This study was undertaken between May 2016 to May 2017 in the outpatient nephrology and urology clinic of San Donato Hospital in Arezzo. The study population (84 patients: 47 males and 37 females) was randomly selected among the chronic kidney patients (with various degrees of renal impairment) affected by hypertension and or diabetes mellitus. After a comprehensive medical examination these patients were submitted to determination of serum creatinine, glycated hemoglobin, 24-hour urinary albumin excretion and finally renal Doppler ultrasonography. Then the patients were submitted to a full therapeutic and dietetic intervention to ameliorate the renal impairment by a wide range of actions and after on average a one-year interval were submitted again to a new medical examination and a second determination of serum creatinine, glycated hemoglobin, 24-hour urinary albumin excretion and a new renal Doppler ultrasonography too. RESULTS: The comparison between basal and final data revealed a slight reduction in the mean of bilateral renal resistance indices (Delta RRI: -0.0182 +/- 0.08), associated to a slight increase in the mean glomerular filtration rate (Delta GFR: 0.8738 +/- 10.95 ml/min/1.73 m2), a reduction in mean body weight (Delta weight: -1.9548 +/- 5.26 Kg) and mean BMI (Delta BMI: -0.7643 +/- 2.10 Kg/m2) as well as a reduction in the mean systolic blood pressure (Delta systolic blood pressure: -8.8333 +/- 25.19 mmHg). Statistical analysis showed statistically significant correlations (p < 0.05) between Delta RRI and Delta weight (p < 0.03), Delta BMI (p < 0.02) and Delta systolic blood pressure (p < 0.05). CONCLUSION: Despite the many limitations the our study clearly identifies the targets (yet widely known) to act on to prevent kidney alterations related to RRI and provides further evidence, if any, of the utility of RRI as a key parameter in monitoring patients with chronic renal failure and as a valuable tool to drive the clinical efforts to contrast the kidney disease. PMID- 29473381 TI - Effectiveness on mild stress and mixed urinary incontinence and impact on Quality of Life of a phytotherapic product containing astragalus, thyme, lavender, hop, equisetum, red clover, cypress and agrimonia at titrated concentrations. Results from a monocentric study. AB - OBJECTIVES: To assess any beneficial effect on quality of life of a daily treatment with a phytotherapic product containing astragalus, thyme, lavender, hop, equisetum, red clover, cypress and agrimonia at titrated concentrations in a cohort of female patients complaining mild stress urinary incontinence (SUI) or mixed urinary incontinence (MUI). MATERIALS AND METHODS: 42 non-consecutive female out-patients with mild SUI or mild MUI were assessed with a clinical evaluation, International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF) and Patients' Perception of Intensity of Urgency Scale (PPIUS) at baseline the start of the study and after two months of therapy with the phytotherapic product. At the end of the therapy the patients also compiled Patient Global Impression of Improvement (PGI-I). RESULTS: After the completion of the study there was a trend towards better results in each item of ICIQ-SF, but without any statistical significance with an average score in ICIQ-SF-1 of 3.12 +/- 0.981 versus 3.21 +/- 0.914 (p = 0.556), in ICIQ-SF-2 of 3.69 +/- 1.422 versus 3.79 +/- 1.372 (p = 0.68) and in ICIQ-SF-3 of 5.95 +/- 1.618 versus 6.14 +/- 1.670 (p = 0.462). The average reduction of PPIUS was of 0.09 (1.26 +/- 1.481 versus 1.357 +/- 1.509, p = 0.705). There was a reduction of average consumption of pads/die from 1.69 +/- 0.636 to 1.54 +/- 0.543 (p = 0.101). In relation to the PGI score, 23/42 patients (54.7%) reported no changes after the completion of the therapy, 13/42 (30.9%) reported a slight improvement, 5/42 (11.9%) were much improved and 1/42 (2.3%) was slightly worsened. Only 2/42 (4.7%) patients discontinued the treatment before of the completion of the study. We did not observe any adverse effects during the period of the study. CONCLUSIONS: The phytotherapic product seems to cause a slight improvement of the symptoms in a good rate of patients. Moreover it has a low rate of withdrawal, due to the lack of adverse events. PMID- 29473382 TI - A randomized, multicenter, controlled study, comparing efficacy and safety of a new complementary and alternative medicine (CAM) versus Solifenacin Succinate in women with overactive bladder syndrome. AB - INTRODUCTION: To assess efficacy and tolerability of a new complementary and alternative medicine (CAM) consisting of vitamins (C and D), herbal products (cucurbita maxima, capsicum annum, polygonum capsicatum) and amino acid L Glutammina, in the treatment of female Overactive Bladder syndrome (OAB). MATERIALS AND METHODS: 90 consecutive women with OAB symptoms were enrolled in this prospective, randomized, controlled study. Women were divided randomly into two groups of 45 patients each. In group A, women received Solifenacin Succinate (SS), 5 mg. once a day for 12 weeks. In group B, women received CAM, 930 mg, twice daily for 12 weeks. Women were assessed with 3-day micturition diary, Patient Perception of Intensity of Urgency Scale (PPIUS), Overactive Bladder questionnaire Short Form (OAB-q SF) and Patient Global Impression of Improvement questionnaire (PGI-I). RESULTS: 8 patients in group A and 1 patient in group B dropped out from therapy because of side effects. A reduction in the number of daily micturitions, nocturia and episodes of urge incontinence was present with both SS and CAM with statistically highly significant differences, but CAM was significantly more effective than SS. PPIUS and OAB-q SF showed improvements with both SS and CAM with a more significant efficacy of CAM. PGI-I, demonstrated improvements in the two groups of patients with a greater satisfaction expressed by patients treated with CAM. CONCLUSIONS: the small number of patients does not permit definitive conclusions; however, the results of the research showed the greater effectiveness and tolerability of CAM. PMID- 29473383 TI - Prevalence of phimosis and foreskin sliding abnormalities in male adolescents and their correlation with later onset of first sexual intercourse. AB - INTRODUCTION AND OBJECTIVES: The aim of the study is to evaluate the prevalence of andrological abnormalities, such as phimosis and foreskin sliding abnormalities among male adolescents, and if these might interfere with sexuality, leading to a later onset of sexual experiences. MATERIAL AND METHODS: Between April and May 2015 a prevention campaign in andrology was conducted in an area surrounding Rome, Ostia and the Ladispoli area, among 15-19 year-old students. The screening consisted of a frontal lesson with the students in order to explain and raise the awareness of the most common andrological abnormalities and diseases. Among the routine anamnestic questions, three additional questions were submitted to 18-year-old boys: "Have you ever had sexual intercourse?", "How old were you when you had your first sexual intercourse?" and "Have you consulted a health professional about your genitals?" Finally a detailed clinical examination was performed and the outcome sent to the family and to the General Practitioner (GP). RESULTS: A total of 552 high school students were evaluated. Out of them 131 (23.7%) were at least 18 years old. Among these, 79 (60.3%) said that they had already had full sexual intercourse. The phimosis and foreskin sliding abnormalities had a prevalence of 12.9% within the 18-year-old students, with a significant prevalence among those who hadn't had any sexual intercourse at all, 21.1% vs 7.5% p = 0.023. The age of the complete first sexual experience in the circumcised young men was the same as those without phimosis; 89% of the boys with phimosis hadn't had an andrological examination in the previous years. CONCLUSIONS: Male adolescents with phimosis or preputial sliding abnormalities tend to have a late onset of sexual experiences compared to same aged boys without phimosis. These data support the urgent need of an andrological consultation for all boys at the beginning of, and during, their adolescent period because genital abnormalities may interfere with sexuality. Finally, in order not to confuse effects with causes, we suggest matching a routine genital physical examination in all studies dealing with sexual psychological aspects of male adolescents. PMID- 29473384 TI - Five-year prospective study on cardiovascular events, in patients with erectile dysfunction and hypotestosterone. AB - OBJECTIVE: Testosterone levels play a role in cardiac and vascular pathology. In the present study we investigated the prognostic significance of this hormone for cardiovascular outcome, in a 5-year follow-up. MATERIALS AND METHODS: Our cohort included 802 adult subjects, from 40 to 80 years. Patients were excluded if they had a past history of peripheral or coronary artery disease, and revascularization. A blood sample was drawn to valuate testosterone level, and we considered normal testosterone levels 300 ng/dl. FMD (flow mediated dilatation) of the brachial artery was assessed by measuring the increase of the brachial artery diameter during reactive hyperemia after transient forearm ischemia. B mode longitudinal images of the brachial artery were obtained at the level of the antecubital fossa. The FMD was defined as the percentage change in the brachial artery diameter 60 s after releasing the ischemic cuff. Erectile dysfunction (ERD) was assessed by the International Index of Erectile Function-5 (IIEF-5) score questionnaire. We considered composite end points including the following major adverse cardiovascular events (MACEs) Results: Subjects with lower serum testosterone levels (n = 332) had higher prevalence of traditional cardiovascular risk factors, such as hypertension (p = 0.009), diabetes (p = 0.03), dyslipidemia (p < 0.0001), obesity (p = 0.002), and endothelial function score (p < 0.0001). AMI, death after AMI, major stroke and all clinical events were more frequent (p < 0.001) in patients with testosterone levels < 300 ng/dl. Further, by multiple logistic regression analysis we found that only dyslipidemia (p = 0,001), obesity (p = 0,007), testosterone < 300 ng/dl (p < 0,0001) and ED (p < 0,0001) were independent predictors of future events. CONCLUSIONS: A therapeutic intervention on testosterone may not only have a positive effect on the cardiovascular system but also an important role in preventing new cardiovascular events.

AB - Primary neuroendocrine carcinoma of the kidney is a rarely observed clinical condition because neuroendocrine cells are not found in kidney parenchyma. It's not clinically and radiologically possible to distinguish from other kidney tumors. Incidence with horseshoe kidney anomaly, it should be considered as a definitive diagnosis for the patients with this condition. In this case report, we reported about a carcinoid tumor in horseshoe kidney in a 37-year-old woman. PMID- 29473386 TI - Incidentally discovered pelvic paraganglioma: A case report. AB - Paragangliomas (PGL) are rare neuroendocrine tumors of the autonomic nervous system originating from paraganglia. Although PGL may arise at any site where physiologic paraganglionic tissue exists, the localization in the small pelvis is extremely rare. PGL may be hormonally active and release surplus catecholamines into the blood or inactive. The asymptomatic cases pose a diagnostic dilemma. We describe the case of an asymptomatic PGL arising in the small pelvis sidewall presenting as an incidentally discovered asymptomatic mass in a male subject. PMID- 29473387 TI - Elderly patient with atypical leiomyoma of the bladder presenting as flank pain: A case report. AB - Atypical leiomyoma is a rare tumor of the bladder whose correct diagnosis with imaging techniques and cystoscopy is difficult. This tumor is prevalent in females and more common in middle age. In the present study we report a rare case of atypical leiomyoma presenting as flank pain and history of recurrent urinary tract infections in an elderly female. Ultrasound (US) showed that the wall of bladder was thickening and irregular, especially in the lower part of the bladder. US revealed hypoechoic solid mass with dimensions of 37 x 26 mm in the posterior bladder wall protruding into the bladder. Computed Tomography scan of the patient showed a mass with dimensions of 29 x 38 mm in the posterior wall of the bladder that infiltrated the mesenteric fat and also seemed to be invading the intestinal wall. According to the general condition and age of our patient, we removed all of the mass under spinal anesthesia by transurethral bladder resection (TURBT). Biopsy results showed atypical leiomyoma. About 6 months after the patient follow-up, no recurrence was observed and symptoms had completely resolved. According to the non-specificity of the imaging, of the age of presentation and of clinical manifestations of atypical leiomyoma differential diagnosis for bladder cancer it is recommended. Only with histopathologic findings, the diagnosis can be confirmed. PMID- 29473388 TI - Seminal vesicle abscess causing unilateral hydroureteronephrosis: A case report.

We describe the case of a diabetic subject with SVA associated with funiculitis, epididymitis and obstructive pyelonephritis. Treatment consisted of laparotomic surgical drainage of the abscess and ureteral stent placement. PMID- 29473389 TI - Right ectopic intrathoracic kidney: Unusual clinical presentation in a young patient affected by scrotal varicocele. AB - Intrathoracic kidney is a partial or complete displacement of the kidney above the hemidiaphragm into the mediastinal compartment of the thorax. It is usually seen as an incidental finding discovered on chest radiograph or abdominal ultrasound. However computed tomography consents the correct detection of intrathoracic masses and defines their shape, size, and extent. We here report a case of ectopic thoracic kidney in a 22-year-old man who had a long history of scrotal discomfort associated with right varicocele. Frequently, this ectopia does not affect renal function and the stretched ureter provides good drainage. In literature, a small number of cases shows that varicocele is a possible mode of presentation of kidney tumors, but this is the first case of varicocele secondary to intrathoracic kidney ectopia.

AB - OBJECTIVE: Over recent years, therapeutic patient education has become part of dental medicine. Management of early childhood caries, known to be a very common chronic disease, has evolved to include an educational dimension. The objective of this study was to identify the levers and barriers to the development of formalized therapeutic education programmes and alternatives. METHODS: A comprehensive exploratory qualitative study was conducted between November 2015 and June 2016 on a targeted sample of 15 people aware of the problem of TPE in dentistry. RESULTS: The study showed that TPE training in dentistry is underdeveloped, despite its numerous benefits: change of the healthcare professional's approach, implementation of structured educational programmes, development of research, etc. There are many obstacles to the development of TPE programmes: insufficient resources, rigid legislation or lack of knowledge of TPE practices. The dental profession is an obstacle itself because of its lack of understanding and variable degrees of integration the medical community. There are multiple levers, but the main ones are changing attitudes of the profession and the provision of resources to develop TPE. Although alternatives to TPE programmes exist (accompanying measures, short educational strategies, connected health), they cannot replace TPE. CONCLUSION: More educational strategies must be developed in the field of dentistry. However, the framework of TPE must be adapted to the profession to ensure good uptake.

AB - INTRODUCTION: Electronic cigarettes are smokeless devices that simulate the act of tobacco smoking by spraying an ?e-liquid? and diffusing an aerosol that is inhaled by the user. Although the initial enthusiasm observed in 2012-2013 has tended to flag, electronic cigarettes are now part of the landscape of smokers seeking an alternative to smoking and abstinence. Smoking cessation professionals need to meet a growing demand from smokers and must adopt a clear position in relation to this device. METHODS: The results presented here were derived from a qualitative study conducted with the financial support of the French Directorate of Health, part of the Ministry of Social Affairs and Health from September 2014 to January 2016. RESULTS: The study was based on classical field-work ethnology: observations were made during events involving electronic cigarette users and 25 semi-structured interviews with diverse profiles to clarify a poorly known field. This study contributes to the observation and understanding of an emerging phenomenon, likely to induce a lasting change in our relationship to tobacco. DISCUSSION: The study revealed a wide variety of profiles among smokers interested by electronic cigarettes. Men and women, young and old, or former smokers, adopt various attitudes when trying this device, and their patterns of use often change over the months following initiation. PMID- 29473394 TI - [Outbreak of carbon monoxide poisoning in the Ile-de-France region during the spring 2016 Seine flooding]. AB - INTRODUCTION: Heavy rainfall in May 2016 caused large-scale flooding of the Seine and its tributaries. Analysis of this unusual event showed that it could recur on an even larger scale. The sanitary consequences were less frequently assessed in this analysis, particularly the risk of accidental collective carbon monoxide (CO) poisoning caused by the use of combustion engine drainage pumps. METHODS: We retrospectively reviewed all cases of acute accidental carbon monoxide exposure observed in the Ile-de-France region, related to the use of drainage pumps in spring and summer 2016 and notified to the Ile-de-France CO poisoning surveillance network. RESULTS: Five events were identified, including 45 people exposed to carbon monoxide. Thirty-four of these people were poisoned, 5 were not poisoned and insufficient data were available for 6 people. Three people showed signs of severity and 2 were treated by hyperbaric oxygen therapy. The other poisoned individuals were managed in hospital and treated by oxygen therapy. All were cured. DISCUSSION: Collective CO poisonings are common sanitary events during flooding and can be potentially severe. They can occur during the event or over the following days. Preventive measures may help to reduce the risk of CO poisoning, such as increased awareness among professionals, better information of individuals who rent these types of devices or even the use of CO detectors during their use. PMID- 29473395 TI - [Health literacy and patient education interventions: a review]. AB - INTRODUCTION: Low health literacy (HL) is an obstacle to therapeutic patient education (TPE), especially for people in a vulnerable situation, who are also at greater risk of chronic illnesses and their complications. It therefore seems essential to rethink TPE programmes in order to ensure greater equity based on analysis of the characteristics of HL interventions and their possible relationships with TPE. METHODS: A scoping review of the literature was performed from November 2014 to January 2016 using the following search engines: MEDLINE/PubMed, EMBASE, PsycINFO, ERIC, OpenGrey, SUDOC, theses.fr and BDSP and the following search terms: ?health literacy?, ?Litteratie en sante?, ?literacy?, ?Litteratie?, ?numeracy?, ?numeratie?, ?competence en sante? combined with the keywords: ?programme?, ?program?, ?intervention?, ?methode?, ?method?, ?technique?, ?outil?, ?tool?. RESULTS: After selecting forty out of 206 studies, interventions were classified into two main types of specific interventions to promote comprehension of resources intended for patients and generally complex interventions designed to support and improve HL skills. DISCUSSION: While the level of health literacy has an impact on TPE programme accessibility, TPE programmes need to be made more accessible and TPE must constitute an opportunity to address health literacy needs via its own specific modalities. Creating partnerships between social/educational and health settings might be an effective strategy to strengthen the interrelationships between HL and TPE, as might training that prepares caregivers-educators to improve patient HL. CONCLUSION: Interrelationships between HL and TPE are possible. Research should question the pedagogical modalities to be used to adapt TPE programs to the HL.

AB - OBJECTIVE: To present the process and challenges of developing an online competency-based course on public health policy using a collaborative international approach. METHODS: Five public health experts, supported by an expert in educational technology, adopted a rigorous approach to the development of the course: a needs analysis, identification of objectives and competencies, development of a pedagogical scenario for each module and target, choice of teaching methods and learning activities, material to be identified or developed, and the responsibilities and tasks involved. RESULTS: The 2-credit (90-hour) graduate course consists of six modules including an integration module. The modules start with a variety of case studies: tobacco law (neutral packaging), supervised injection sites, housing, integrated services for the frail elderly, a prevention programme for mothers from disadvantaged backgrounds, and the obligatory use of bicycle helmets. In modules 1, 3, 4 and 5, students learn about different stages of the public policy development process: emergence, formulation and adoption, implementation and evaluation. Module 2 focuses on the importance of values and ideologies in public policy. The integration module allows the students to apply the knowledge learned and addresses the role of experts in public policy and ethical considerations. CONCLUSION: The course has been integrated into the graduate programmes of the participating universities and allows students to follow, at a distance, an innovative training programme. PMID- 29473397 TI - [Psychiatric readmissions: individual and organizational factors]. AB - BACKGROUND: Psychiatric readmission often constitutes a criterion to assess the effects of various therapies, as well as the impact of organizational changes in the healthcare system. It is used to characterize relapse or decompensation. The purpose of this study was to determine readmission rates and identify individual and organizational factors associated with significant variations in these rates. METHODS: Adult psychiatric readmissions were identified from the full-time hospital stays registered in psychiatric wards in 2011-2012 in the Nord and Pas de-Calais departments of France, available in the medical the RimP psychiatric admission database. Readmission rates for various follow-up periods after discharge were measured by Kaplan-Meier survival analysis and multivariate analysis was conducted using the Cox proportional hazards model. RESULTS: Approximately 30,000 adults were hospitalized full-time in psychiatric units of the region during the study period. The 24-month readmission rate was 51.6% (95%CI: 50.8-52.3%). The Cox model showed that a diagnosis of schizophrenia (F2 - HR = 1.72 - 95%CI: 1.61-1.84 - p < 0.001) and personality disorder (F6 - HR = 1.45 - 95%CI: 1.32-1.58 - p < 0.001) was associated with a higher readmission rate. Readmission rates were higher among dependent patients in non-profit private hospitals. CONCLUSION: Psychiatric readmission is a very frequent event and is linked to organizational as well as individual factors. PMID- 29473398 TI - [Factors influencing electronic personal health record (ePHR) adoption by Primary Health Care providers in Quebec: Professional and organizational perspective]. AB - INTRODUCTION: We aimed to describe and analyse the factors and conditions influencing ePHR adoption by primary healthcare professionals for the follow-up and management of chronic diseases, as perceived by healthcare professionals and health organization managers. METHODS: A qualitative study was conducted in the context of an ePHR experimentation project in Quebec. In-depth semi-structured individual interviews were conducted with 11 professionals and three managers directly involved in ePHR implementation in a primary healthcare organization. RESULTS: The results highlight the emergence of themes comprising facilitators or barriers to ePHR adoption. The main factors identified were the clinicians' leadership and previous involvement in organizational transformations, the context of practice, technology maturity providing a useful, additional and relevant content, integration with the available clinical information systems facilitating two-way communication and supporting the development of patient professional partnerships and patients' use and adherence. The organizational precursors identified refer to the organizational receptivity to change, adjustment to participants' values, and the policies and practices set up to support ePHR adoption by professionals and their patients. Cost is a major issue determining ePHR implementation. CONCLUSION: The factors and conditions identified will be useful strategically and operationally to design and implement new clinical and organizational practices and develop adapted technologies facilitating ePHR adoption by professionals.

AB - INTRODUCTION: The great majority of French people express their desire to receive palliative care at home. The objective of this study was to describe the clinical care pathways and characteristics of patient receiving hospital at home palliative care. METHODS: This study compared the care pathways and clinical characteristics of patients receiving palliative care at home in the Ile-de France region in 2014. Retrospective data were extracted from the French medical information systems programme. RESULTS: 817 patients receiving palliative care at home were included in the study. They were older, more often referred to hospital at home by a primary care physician, had shorter lengths of stay and more often died at home compared to patients without palliative care. Palliative care patients mainly presented cancer and received frequent technical nursing care. The oldest patients (>= 75 years old) more often presented neurodegenerative diseases, were less often transferred to hospital, and more often died at home compared to younger patients. A higher proportion of home deaths was observed in nursing home residents and patients who died at home required less technical nursing care. CONCLUSION: This study provides important information concerning admission to hospital at home, the frequent changes of places of care and the complexity of maintaining palliative care at home until the patient's death.

AB - OBJECTIVE: While waiting for health insurance coverage, unaccompanied foreign minors (UFM) can attend PASS healthcare access clinics in French hospitals. The aim of this study was to identify UFM's representations and perceptions of the French health care system. METHODS: This qualitative study was based on a series of individual, semi-structured interviews of UFMs attending a PASS clinic. The methodology was approved by the French data protection authority and an ethics committee. RESULTS: A total of 21 UFMs were interviewed. Participants expressed their satisfaction with health care, although the health care system was perceived as a complex system. The prescription is essential, as it enables the patient to obtain medications, the ultimate goal of health care access. Not all participants knew about the existence of national health insurance. They were unable to distinguish between PASS clinics and the hospital in general and the screening role of PASS clinics was often poorly understood. The general practitioner was not always identified and his role was poorly understood. Educators were perceived as playing a decisive role in health care access. Heath is essential for all UFMs. None of them referred to mental health issues. CONCLUSION: UFMs need better information about the health care system and their rights. The educators' health care support training, their knowledge of the rights of UFMs and the role of healthcare professionals need to be improved. Screening of mental illness needs to be developed.

AB - INTRODUCTION: The objective of this study was to elucidate the conditions of emergence of patient safety issues in the public debate and the limits to implementation of patient safety in the current health system. METHOD: A narrative review of the international literature was conducted by searching PubMed, Cairn and Persee databases. RESULTS: The database search retrieved 2,206 documents, 48 of which were included in the study. The theme of patient safety has spread worldwide, but emerged late in France. The delayed emergence of patient safety in France is essentially related to the euphemistic approach to the problem of patient safety, the difficulty of adopting systematic reasoning, the lack of human resources management levers and the ambiguous position of patients in relation to patient safety. PMID- 29473402 TI - [Health Statistics in Senegal: between political stakes and role playing]. AB - INTRODUCTION: Many countries have developed disease surveillance systems to deal with epidemics, but although health information systems have existed for more than two decades, constraints and biases in data collection limit the relevance of policy decisions and strategies in the field of health, as priority has been given to education and health in developing countries. Donor support has led to the development of systems for the production of statistics, designed, among other things, to more clearly target interventions in terms of educational objectives, action and credibility and enable health systems to continue to benefit from external funding. METHODS: We used a classical anthropology approach based on observations and in-depth interviews with local and national health system actors. RESULTS: The aim of this article is to analyse the real effects of the production of health statistics in health care systems and to determine the relevance of these figures in the context in which they apply. DISCUSSIONS: Health priorities defined by international organizations and technical and financial partners focus on diseases considered to be ?priorities? to the detriment of neglected diseases, which are perceived as being more important at the local level due to their impact on the already limited health systems. We describe how health actors within healthcare structures adjust and adapt to public health requirements. PMID- 29473403 TI - [Job perception and well-being among healthcare workers in Morocco]. AB - OBJECTIVES: The aim of this study was to evaluate the well-being and occupational perception of healthcare workers in Morocco. METHODS: This observational and cross-sectional survey, carried out by self-administered questionnaire, was conducted in public hospitals in three cities. The target population consisted of 2,453 healthcare workers, comprising physicians and paramedics with at least two years of clinical experience. RESULTS: 1951 healthcare workers returned the questionnaire (29.4% physicians and 70.6% allied health personnel).The mean age was 40.3 +/- 10.1 years. 79.8% drank tea and 59.6% drank coffee daily to remain alert at work. 13.9% were smokers and 5.5% drank alcohol. Medication use consisted of analgesics for 28.1% and psychotropic drugs for 11.6%. The respective prevalence of general health perception was ?bad or very bad? for 14.1% to 24.5%. Perceived symptoms varied from 20.4% to 26.2%. Pain and headache were the most common symptoms. 53.9% ?often and continuously? experienced stress at work. Work requirements were considered to be ?difficult? or ?very difficult? by 32.1% to 46.2%.The workplace was unsuitable for 37.2%, salary was inadequate for 39.4%, the workload was excessive for 39.8% and the work rate was excessive for 43.2%. Relationship with colleagues (work environments and trust) were appropriate for 55.6% and 65%, respectively. Relationships with hierarchical superiors were appropriate for 15.6% and based on confidence for 13.8%. Perceived social support outside of work was high. CONCLUSION: Assessment of well-being and occupational risk perception among healthcare workers must be one of the priority tasks of occupational health utilities in Moroccan hospitals.

AB - BACKGROUND: Stigma and discrimination experienced by people living with HIV (PLWHA) prevent and delay access to prevention and treatment services. The aim of this study was to describe the patterns of stigma and discrimination experienced by PLWHA in Togo and to identify the associated factors. METHODS: A cross sectional study was conducted in 2013 among PLWHA in Togo in order to collect data on stigma or discrimination experiences. Univariate and multivariate analyses were performed to identify associated factors. RESULTS: A total of 891 PLWHA were interviewed, including 848 (95.2%) receiving antiretroviral therapy. External stigma (37.9%) was the major form of stigmatization followed by internalized stigma (35.4%). The main features of external stigma were gossip (36.5%) and issues to access education (36.0%). Internalized stigma mainly consisted of a feeling of guilt (37.6%) and self-devaluation (36.0%). In univariate and multivariate analysis, female gender was significantly associated with stigma (aOR = 1.73, 95% CI [1.08-2.77]). Of the 891 PLWHA, 75 (8.4%) reported a violation of their rights. Finally 27 (4.1%) were discouraged from having children by a health professional because of their HIV status. CONCLUSION: Stigma affects more than one-third of PLWHA in Togo, more particularly females. It appears necessary to design new interventions and integrate psychosocial care in the management of PLWHA, in addition to antiretroviral therapy. PMID- 29473405 TI - [A meta-synthesis on gender, disability and reproductive health in sub-Saharan Africa]. AB - INTRODUCTION: Reproductive health remains a major global health issue. People with disabilities face additional discrimination and barriers to access which need to be better understood. To contribute to future interventions, we examined the intersections between gender and disability related to reproductive health in sub-Saharan Africa in the qualitative literature. METHODS: We conducted a meta synthesis, using a taxonomic analysis. An inductive and iterative approach was adopted to allow exploration of new and emergent semantic variations in themes. NVivo 11 Plus was used to code themes. RESULTS: Ten qualitative studies from six sub-Saharan African countries were analysed. Two main thematic areas emerged from the analysis: 1) gendered roles of people with disabilities are programmed by sociocultural normativity, including perceptions about sexuality. They are exacerbated by the hegemony of ableism and influenced by the type of reproductive health issues experienced by people with disabilities; and 2) experiences of disability in interaction with a reproductive health issue are exacerbated by the type of disability, influenced by the type of barriers to access, and perceived differently depending upon the actors involved. DISCUSSION: The intersections between gender and disability embodied by people with disabilities are multiple and complex. Not only do imposed gendered roles influence the lives of people with disabilities, but their experiences of disability are also intricately linked to gender. An intersectional analysis is proposed as a useful support to developing future perspectives. PMID- 29473406 TI - ? AB - Large-scale deployment of new medicines has been observed over the last two decades in many Sub-Saharan Africa countries faced with major public health issues such as malaria and HIV/AIDS. However, some of these medicines may be responsible for varying degrees of toxicity, with adverse drug reactions leading to decreased compliance or even discontinuation of treatment. Pharmacovigilance systems therefore had to be set up in these countries, such as in Burkina Faso, West Africa, which initiated the organization of pharmacovigilance activities in 2008. Despite this progress, the systems in place have not yet achieved a sufficient level of performance to deal with drug-related health issues, highlighting the need for further actions. Pharmacovigilance in Burkina Faso can be strengthened at multiple levels: pre-service and in-service training of health workers; the establishment of active surveillance based on sentinel sites; informing the public and raising awareness; and strengthening national coordination. PMID- 29473409 TI - Self-Powered Temperature-Mapping Sensors Based on Thermo-Magneto-Electric Generator. AB - We demonstrate a thermo-magneto-electric generator (TMEG) based on second-order phase transition of soft magnetic materials that provides a promising pathway for scavenging low-grade heat. It takes advantage of the cyclic magnetic forces of attraction and repulsion arising through ferromagnetic-to-paramagnetic phase transition to create mechanical vibrations that are converted into electricity through piezoelectric benders. To enhance the mechanical vibration frequency and thereby the output power of the TMEG, we utilize the nonlinear behavior of piezoelectric cantilevers and enhanced thermal transport through silver (Ag) nanoparticles (NPs) applied on the surface of a soft magnet. This results in large enhancement of the oscillation frequency reaching up to 9 Hz (300% higher compared with that of the prior literature). Optimization of the piezoelectric beam and Ag NP distribution resulted in the realization of nonlinear TMEGs that can generate a high output power of 80 MUW across the load resistance of 0.91 MOmega, which is 2200% higher compared with that of the linear TMEG. Using a nonlinear TMEG, we fabricated and evaluated self-powered temperature-mapping sensors for monitoring the thermal variations across the surface. Combined, our results demonstrate that nonlinear TMEGs can provide additional functionality including temperature monitoring, thermal mapping, and powering sensor nodes. PMID- 29473410 TI - Determination of Nanoparticle Size Using a Flow Particle-Tracking Method. AB - We developed a novel method to determine the mean size of nanoparticles under flow conditions, the flow particle-tracking (FPT) method. The liquid particle counting method is commonly utilized to determine number-based size under flow conditions by converting the light scattering intensity of individual particles to size using the relationship between the size and light scattering intensity of a size standard material; however, the determined size depends strongly on the type of size standard material. In contrast, the developed FPT method can reliably determine the mean size of nanoparticles under flow conditions according to the Stokes-Einstein assumption by observing the Brownian motion of individual particles; therefore, this method does not require a calibration step using a size standard and can be applied to any type of material. To reliably size particles under flow conditions, we determined the flow velocity profile in a sample cell by extracting only the flow velocity from the particle motion. After determining the self-diffusion coefficient of each particle and subtracting the effect of the flow velocity, we successfully obtained a reliable mean size. The developed method could contribute to the application of microchannel reaction/synthesis devices using nanomaterials. PMID- 29473408 TI - Adaptation of Operational Parameters of Cold Atmospheric Plasma for in Vitro Treatment of Cancer Cells. AB - Cold atmospheric plasma (CAP), an ionized gas operated at near-ambient temperatures, has been introduced as a new therapeutic opportunity for treating cancers. The effectiveness of the therapy has been linked to CAP-generated reactive oxygen and nitrogen species such as hydrogen peroxide and nitrite. In this study, we monitor in real-time cancer cell response to CAP over the course of 48 h. The results demonstrate a correlation between cell viability, exposure time (30, 60, 90, and 180 s), and discharge voltage (3.16 and 3.71 kV), while stressing the likely therapeutic role of plasma-generated reactive species. A 30 60 s increase in CAP exposure time and/or a discharge voltage adjustment from 3.16 to 3.71 kV is consistently accompanied by a significant reduction in cell viability. Comparably, levels of hydrogen peroxide and nitrite vary as a function of voltage with elevated levels detected at the highest tested voltage condition of 3.71 kV. CAP ultimately initiates a reduction in cell viability and triggers apoptosis via damage to the mitochondrial membrane, while also deregulating protein synthesis. The findings presented in this study are discussed in the context of facilitating the development of an adaptive CAP platform which could improve treatment outcomes. PMID- 29473411 TI - Levamisole: a Common Adulterant in Cocaine Street Samples Hindering Electrochemical Detection of Cocaine. AB - The present work investigates the electrochemical determination of cocaine in the presence of levamisole, one of the most common adulterants found in cocaine street samples. Levamisole misleads cocaine color tests, giving a blue color (positive test) even in the absence of cocaine. Moreover, the electrochemical detection of cocaine is also affected by the presence of levamisole, with a suppression of the oxidation signal of cocaine. When levamisole is present in the sample in ratios higher than 1:1, the cocaine signal is no longer detected, thus leading to false negative results. Mass spectrometry and nuclear magnetic resonance were used to investigate if the signal suppression is due to the formation of a complex between cocaine and levamisole in bulk solution. Strategies to eliminate this suppressing effect are further suggested in this manuscript. In a first approach, the increase of the pH of the sample solution from pH 7 to pH 12 allowed the voltammetric determination of cocaine in the presence of levamisole in a concentration range from 10 to 5000 MUM at nonmodified graphite disposable electrodes with a detection limit of 5 MUM. In a second approach, the graphite electrode was cathodically pretreated, resulting in the presence of oxidation peaks of both cocaine and levamisole, with a detection limit for cocaine of 3 MUM over the linear range of concentrations from 10 to 2500 MUM. Both these strategies have been successfully applied for the simultaneous detection of cocaine and levamisole in three street samples on unmodified graphite disposable electrodes. PMID- 29473412 TI - Novel Patterning Method for Nanomaterials and Its Application to Flexible Organic Light-Emitting Diodes. AB - We present a simple, low-cost, and scalable method to form various patterns of nanomaterials with different dimensions and shapes using capillary and centrifugal forces. The desired patterns were formed on the surfaces of poly(dimethylsiloxane) (PDMS) stamps, and the PDMS stamps were conformally contacted with the surfaces of flexible polymer substrates. Solutions of nanomaterials, such as metal nanowires and nanoparticles, were then drop-casted at one open end of the microchannels formed at the interface of the polymer substrate and PDMS stamp. The nanomaterial solutions penetrated the microchannels due to capillary force interactions between the surfaces and the fluid. The solvents of the nanomaterial solutions exfiltrated from the entrance of microchannels because of the coffee ring effect. Then, the solvent remaining in the microchannels was discharged by applying a centrifugal force by spinning the polymer substrate/PDMS stamp system. Because of the synergistic effect of the capillary force, coffee ring effect, and centrifugal force, uniform patterns of the nanomaterials with clearly defined edges were formed for a variety of pattern shapes and substrates. Furthermore, the direct patterning approach resulted in a significant reduction in the amount of wasted materials. Finally, flexible organic light-emitting diodes were successfully fabricated on the finely patterned nanowire electrodes. PMID- 29473413 TI - Expanding One-Pot Cell-Free Protein Synthesis and Immobilization for On-Demand Manufacturing of Biomaterials. AB - Fabrication of protein-based biomaterials is an arduous and time-consuming procedure with multiple steps. In this work, we describe a portable toolkit that integrates both cell-free protein synthesis (CFPS) and protein immobilization in one pot just by mixing DNA, solid materials, and a CFPS system. We have constructed a modular set of plasmids that fuse the N-terminus of superfolded green fluorescent protein (sGFP) with different peptide tags (poly(6X)Cys, poly(6X)His, and poly(6X)Lys), which drive the immobilization of the protein on the tailored material (agarose beads with different functionalities, gold nanorods, and silica nanoparticles). This system also enables the incorporation of azide-based amino acids into the nascent protein for its selective immobilization through copper-free click reactions. Finally, this technology has been expanded to the synthesis and immobilization of enzymes and antibody-binding proteins for the fabrication of functional biomaterials. This synthetic biological platform has emerged as a versatile tool for on-demand fabrication of therapeutic, diagnostic, and sensing biomaterials. PMID- 29473414 TI - Quantitative Rheometry of Thin Soft Materials Using the Quartz Crystal Microbalance with Dissipation. AB - In the inertial limit, the resonance frequency of the quartz crystal microbalance (QCM) is related to the coupled mass on the quartz sensor through the Sauerbrey expression that relates the mass to the change in resonance frequency. However, when the thickness of the film is sufficiently large, the relationship becomes more complicated and both the frequency and damping of the crystal resonance must be considered. In this regime, a rheological model of the material must be used to accurately extract the adhered film's thickness, shear modulus, and viscoelastic phase angle from the data. In the present work we examine the suitability of two viscoelastic models, a simple Voigt model ( Physica Scripta 1999, 59, 391-396) and a more realistic power-law model ( Langmuir 2015, 31, 4008 4017), to extract the rheological properties of a thermoresponsive hydrogel film. By changing temperature and initial dry film thickness of the gel, the operation of QCM was traversed from the Sauerbrey limit, where viscous losses do not impact the frequency, through the regime where the QCM response is sensitive to viscoelastic properties. The density-shear modulus and the viscoelastic phase angle from the two models are in good agreement when the shear wavelength ratio, d/lambda n, is in the range of 0.05-0.20, where d is the film thickness and lambda n is the wavelength of the mechanical shear wave at the nth harmonic. We further provide a framework for estimating the physical properties of soft materials in the megahertz regime by using the physical behavior of polyelectrolyte complexes. This provides the user with an approximate range of allowable film thicknesses for accurate viscoelastic analysis with either model, thus enabling better use of the QCM-D in soft materials research. PMID- 29473415 TI - Critical Nuclei Size, Rate, and Activation Energy of H2 Gas Nucleation. AB - Electrochemical measurements of the nucleation rate of individual H2 bubbles at the surface of Pt nanoelectrodes (radius = 7-41 nm) are used to determine the critical size and geometry of H2 nuclei leading to stable bubbles. Precise knowledge of the H2 concentration at the electrode surface, CH2surf, is obtained by controlled current reduction of H+ in a H2SO4 solution. Induction times of single-bubble nucleation events are measured by stepping the current, to control CH2surf, while monitoring the voltage. We find that gas nucleation follows a first-order rate process; a bubble spontaneously nucleates after a stochastic time delay, as indicated by a sudden voltage spike that results from impeded transport of H+ to the electrode. Hundreds of individual induction times, at different applied currents and using different Pt nanoelectrodes, are used to characterize the kinetics of phase nucleation. The rate of bubble nucleation increases by four orders of magnitude (0.3-2000 s-1) over a very small relative change in CH2surf (0.21-0.26 M, corresponding to a ~0.025 V increase in driving force). Classical nucleation theory yields thermodynamic radii of curvature for critical nuclei of 4.4 to 5.3 nm, corresponding to internal pressures of 330 to 270 atm, and activation energies for nuclei formation of 14 to 26 kT, respectively. The dependence of nucleation rate on H2 concentration indicates that nucleation occurs by a heterogeneous mechanism, where the nuclei have a contact angle of ~150 degrees with the electrode surface and contain between 35 and 55 H2 molecules. PMID- 29473416 TI - Novel Electrochemical Paper-Based Immunocapture Assay for the Quantitative Determination of Ethinylestradiol in Water Samples. AB - We report a novel and innovative electrochemical paper-based immunocapture assay (EPIA) to address the need for ultrasensitive detection of emerging pollutants without regulatory status and whose effects on environment and human health are not completely yet understood. In particular, we present the application of this system toward highly sensitive detection of the emerging pollutant ethinyl estradiol (EE2). The EPIA approach is based on the use of paper microzones modified with silica nanoparticles (SNs) and anti-EE2 specific antibodies for capture and preconcentration of EE2 from river water samples. After the preconcentration procedure, the paper microzones are placed onto a screen-printed carbon electrode modified with electrochemically reduced graphene (RG). The bound EE2 is subsequently desorbed adding a diluted solution of sulfuric acid on the paper microzones. Finally, recovered EE2 is electrochemically detected by OSWV. The proposed novel methodology showed an appropriate LOD and linear range for the quantification of EE2 for water samples with different origins. The nonsophisticated equipment required, the adequate recovery values obtained (from 97% to 104%, with a RSD less than 4.9%), and the appropriate LOD and linear range value (0.1 ng L-1 and 0.5-120 ng L-1, respectively) achieved by our immunocapture sensor present significant analytical figures of merit, particularly when the routine quantification of EE2 is considered. In addition, our system was based on electrochemical paper-based technology, which allows obtainment of portable, easy to-use, inexpensive, and disposable devices. The EPIA can also serve as a general purpose immunoassay platform applicable to quantitation of other drugs and emerging pollutants in environmental samples. PMID- 29473417 TI - Atomic Detail of Protein Folding Revealed by an Ab Initio Reappraisal of Circular Dichroism. AB - Circular dichroism (CD) is known to be an excellent tool for the determination of protein secondary structure due to fingerprint signatures of alpha and beta domains. However, CD spectra are also sensitive to the 3D arrangement of the chain as a result of the excitonic nature of additional signals due to the aromatic residues. This double sensitivity, when extended to time-resolved experiments, should allow protein folding to be monitored with high spatial resolution. To date, the exploitation of this very appealing idea has been limited, due to the difficulty in relating the observed spectral evolution to specific configurations of the chain. Here, we demonstrate that the combination of atomistic molecular dynamics simulations of the folding pathways with a quantum chemical evaluation of the excitonic spectra provides the missing key. This is exemplified for the folding of canine milk lysozyme protein. PMID- 29473418 TI - Development and Comparison of Air Pollution Exposure Surfaces Derived from On Road Mobile Monitoring and Short-Term Stationary Sidewalk Measurements. AB - Land-use regression (LUR) models of air pollutants are frequently developed on the basis of short-term stationary or mobile monitoring approaches, which raises the question of whether these two data collection protocols lead to similar exposure surfaces. In this study, we measured ultrafine particles (UFP) and black carbon (BC) concentrations in Toronto during summer 2016, using two short-term data collection approaches: mobile, involving 3023 road segments sampled on bicycles, and stationary, involving 92 sidewalk locations. We developed four LUR models and exposure surfaces, for the two pollutants and measurement protocols. Coefficients of determination ( R2) varied from 0.434 to 0.525. Various small scale traffic variables were included in the mobile LUR. Pearson correlation coefficients between the mobile and stationary surfaces were 0.23 for UFP and 0.49 for BC. We also compared the two surfaces using personal exposures from a panel study in Toronto conducted during the same period. The personal exposures differed from the outdoor exposures derived from the combination of GPS information and exposure surfaces. For UFP, the median for personal outdoor exposure was 26 344 part/cm3, while the cycling and stationary surfaces predicted medians of 31 201 and 19 057 part/cm3. Similar trends were observed for BC, with median exposures of 1764 (personal), 1799 (cycling), and 1469 ng/m3 (stationary).

AB - In this study, we systematically explored the mixed-cation perovskite Cs x(MA0.4FA0.6)1- xPbI3 fabricated via sequential introduction of cations. The details of the effects of Cs+ on the fabrication and performance of inorganic organic mixed-cation perovskite solar cells examined in detail in this study are beyond the normal understanding of the adjusting band gap. It is found that a combined intercalation of Cs+ and dimethyl sulfoxide (DMSO) in PbI2-DMSO precursor film formed a strong and steady coordinated intermediate phase to retard PbI2 crystallization, suppress yellow nonperovskite delta-phase, and obtain a highly reproducible perovskite film with less defects and larger grains. The Cs-contained triple-cation-mixed perovskite Cs0.1(MA0.4FA0.6)0.9PbI3 devices yield over 20% reproducible efficiencies, superior stabilities, and fill factors of around 0.8 with a very narrow distribution. PMID- 29473420 TI - Quantum Dots Formed in Three-dimensional Dirac Semimetal Cd3As2 Nanowires. AB - We demonstrate quantum dot (QD) formation in three-dimensional Dirac semimetal Cd3As2 nanowires using two electrostatically tuned p-n junctions with a gate and magnetic fields. The linear conductance measured as a function of gate voltage under high magnetic fields is strongly suppressed at the Dirac point close to zero conductance, showing strong conductance oscillations. Remarkably, in this regime, the Cd3As2 nanowire device exhibits Coulomb diamond features, indicating that a clean single QD forms in the Dirac semimetal nanowire. Our results show that a p-type QD can be formed between two n-type leads underneath metal contacts in the nanowire by applying gate voltages under strong magnetic fields. Analysis of the quantum confinement in the gapless band structure confirms that p-n junctions formed between the p-type QD and two neighboring n-type leads under high magnetic fields behave as resistive tunnel barriers due to cyclotron motion, resulting in the suppression of Klein tunneling. The p-type QD with magnetic field-induced confinement shows a single hole filling. Our results will open up a route to quantum devices such as QDs or quantum point contacts based on Dirac and Weyl semimetals.

PMID- 29473422 TI - Linear and Nonlinear Thermal Lens Signal of the (Deltanu = 6) C-H Vibrational Overtone of Naphthalene in Liquid Solutions of n-Hexane. AB - The thermal lens technique is applied to vibrational overtone spectroscopy of solutions of naphthalene (C10H8) in liquid hexane. The C-H fifth vibrational (Deltanu = 6) overtone spectrum of C10H8 is detected at room temperature for mole fractions from 0.08 to 19 * 10-6 using n-C6H14 as solvent. By detecting the absorption band in a 19 ppm (parts per million) solution, the peak absorption of the signal is approximately (2.2 +/- 0.3) * 10-7 cm-1. A plot of normalized integrated intensity as a function of the mole fraction of naphthalene in solution reveals a dependence of the magnitude of the signal with the probe laser wavelength. If the wavelength of the probe laser is 568 nm, the thermal lens signal (TLS) is linear as a function of the mole fraction of the solution. When the wavelength of the probe laser is 488 nm, the TLS is nonlinear as a function of the concentration. Three different models of nonlinear absorption are discussed. A two-color absorption model that includes the simultaneous absorption of the pump and probe lasers could explain the enhanced magnitude and the nonlinear behavior of the TLS for solutions of mole fraction < 0.1%. PMID- 29473423 TI - Implementation of Proton Pump Inhibitor Deprescription Protocol in Geriatric Residents. AB - BACKGROUND: Deprescribing is a recommended intervention to reduce morbidity and mortality caused by polypharmacy in older residents. However, a lack of definite deprescription guidelines and evidence of clinically meaningful outcomes complicates or precludes the practicality of such an approach. OBJECTIVE: The objective of the present pilot study is to establish and implement a stepwise taper protocol that can potentially minimize overuse of proton pump inhibitors in a safe, effective, and feasible manner in the nursing home. METHODS: Proton pump inhibitor dosage was reduced by half every 3 weeks until the lowest dose was reached; thereafter, the frequency was changed to every other day for 3 weeks, if tolerated. Subsequently, histamine receptor antagonists replaced proton pump inhibitors and followed the same deprescription regimen until discontinuation. Patient-specific interventions also included reassessment of therapeutic agents and dosage forms for more tolerable alternatives to facilitate deprescription efforts and minimize gastric ulceration or discomfort. RESULTS: The pilot study enrolled 10 patients (average age 65.6 years, medication burden 16.8 units, and antisecretory duration 37.5 months). Physicians accepted >95% of interventions, and 90% of patients achieved cessation at 12 weeks. Post cessation, none of the patients needed antacid, prokinetic, or antisecretory agents at 4 weeks. Difficulties in order interpretation and transcription among nurses as well as order entry and calculations among pharmacists were noted. CONCLUSIONS: The present pilot study added to the growing body of evidence that gradual deprescription of antisecretory medications is feasible. Nonetheless, the pilot design precludes any conclusions about safety and efficacy of the intervention. PMID- 29473424 TI - European Society of Cardiology Council for Cardiology Practice worldwide survey of transcatheter aortic valve implantation beliefs and practices. AB - Background Transcatheter aortic valve implantation (TAVI) continues to gain popularity in the management of patients with severe aortic stenosis (SAS). Distribution of resources to maximise appropriate use remains a priority. Design & methods To determine the current perceptions and behaviours regarding SAS patient management, an 18-point multiple-choice questionnaire was distributed to European Society of Cardiology (ESC) Council for Cardiology Practice (CCP) e journal and/or electronic newsletter subscribers. Respondents to all questions were considered. Sub-analyses based on respondent age, practice setting and geographical location were performed. Results Of 1245 full respondents, 41.5% were aged >= 51 years, 22.7% were aged 41-50 years and 35.8% were aged <= 40 years. The majority were located in Europe (77.5%), followed by Asia/Oceania (11.6%), America (7.6%) and Africa (3.4%). In-hospital and out-of-hospital cardiologists accounted for 57.4% of and 28.5% of the sample, respectively, with the remainder being general practitioners/other. The majority of respondents (70.1%) claimed to diagnose between one and five cases of SAS per month. Free access to TAVI was reported by 41.2%, being less common for those aged <= 40 years (32.7%; p < 0.001), those located in Asia/Oceania, America and Africa (20.1%, 18.1% and 2.4%, respectively; p < 0.01 in each case) and in-hospital compared to out-of-hospital cardiologists (35.7% vs. 54.5%, respectively; p < 0.001). The most common reason for not referring a patient for an aortic valve intervention was assessment that the patient was high risk/non-operable (55.5%), followed by short life expectancy (30.5%). The most common reason for referring a patient for TAVI over surgical replacement was surgical risk score (56.9%). The most commonly perceived main complication of TAVI was stroke (28.9%), while the most frequently selected main benefit was improvement in quality of life (37.2%). A high proportion (82.5%) of respondents believed that TAVI is/may become a viable option for lower-risk SAS patients in future. Conclusion The population of potential TAVI is significant worldwide, with key barriers to referral being access limitations and poor physician education. Strategies to minimise these factors are paramount.

AB - Consumers are aware of diet causing health problems and therefore there is an increased demand for natural ingredients that are expected to be safe and health promoting. Many of these compounds belong to the class of flavonoids and can be divided into these five groups: flavanones, flavones, flavonols, flavanols, isoflavones and anthocyanidins. Extracts from citrus fruits are usually used as functional ingredients for several products. The aim of this paper was to develop an UHPLC-UV-ESI-HRMS method to define the metabolite profile of different parts of citrus fruit, of a particular cultivar called 'Ovale Calabrese', and in its main by-products. The high resolution mass spectrometry analysis allowed the identification of 27 compounds belonging to the classes of flavonoids and terpenoids. The high contents of phytochemical compounds, reveal the potential use of the 'Ovale Calabrese' as a rich source of nutraceutical compounds. PMID- 29473426 TI - Factors associated with informant-reported cognitive decline in older adults: A systemised literature review. AB - Background Dementia diagnoses are typically made where there is a significant, progressive decline in cognitive functioning. Evidence of such decline is increasingly established through information provided by informants. However, some studies demonstrate that informant reports may not always be accurate and may be biased by extraneous factors. This review aimed to elucidate factors that have been identified as potentially having some influence on informant reports of cognitive decline. Method A search of PsychInfo, ASSIA, PubMed and Web of Science databases identified 13 peer-reviewed studies that met criteria for inclusion in the review. Results Reviewed studies provide some evidence for associations between informant-reported cognitive decline and demographic characteristics (patient age, education, ethnicity and informant gender), clinical factors (dementia severity, diagnosis, behavioural disturbance, everyday functioning) and psychological factors (patient depressive symptoms and neuroticism, informant psychological distress and burden). Several methodological limitations of the evidence base were identified. Conclusion Findings suggest that informant reported cognitive decline may not always be wholly reliable in that information holds potential to be influenced by both patient and informant characteristics. Clinical and empirical implications are discussed. PMID- 29473427 TI - Glucocorticoid sensitivity and inflammatory status of peripheral blood mononuclear cells in patients with coronary artery disease. AB - OBJECTIVE: Mechanisms behind sustained inflammation in patients with coronary artery disease (CAD) are not clarified but hypothalamus-pituitary-adrenal (HPA) axis dysfunction may have a role. Here, we investigated whether inflammatory status of peripheral blood mononuclear cells (PBMCs) was associated with altered glucocorticoid sensitivity in CAD patients. METHODS: In 55 CAD patients and 30 controls, mRNA levels of GR-alpha, GR-beta, NF-kappaB, IkappaBalpha, MMP-9 and TIMP-1 were measured in PBMCs. Suppressive effects of dexamethasone on GR-alpha, GR-beta, NF-kappaB, IkappaBalpha, MMP-9 and TIMP-1 mRNA levels were assessed in PBMCs ex vivo. Salivary cortisol was repeatedly measured over 3 days. RESULTS: GR alpha mRNA levels were higher in CAD patients than in controls, 0.50 (0.38-0.59) versus 0.26 (0.18-0.37), p < .001, while GR-beta mRNA levels were equally low in both groups. GR-alpha mRNA expression was associated with inflammatory gene expression and, also, with flatter diurnal cortisol rhythm. In both patients and controls, dexamethasone suppressed gene expression of NF-kappaB, IkappaBalpha, MMP-9 and TIMP-1 (p < .001). Dexamethasone also reduced GR-alpha mRNA levels (p < .001), while LPS increased it (p < .001). CONCLUSIONS: PBMCs from CAD patients displayed an inflammatory gene expression profile. This was not explained by reduced glucocorticoid sensitivity. Instead, inflammation was associated with increased expression of GR-alpha mRNA, suggesting a hypocortisolemic state. Key messages * Peripheral blood mononuclear cells from patients with coronary artery disease (CAD) display an inflammatory gene expression profile. * This inflammatory state cannot be explained by reduced glucocorticoid sensitivity in CAD patients. * Instead, the inflammatory gene expression profile is associated with upregulated levels of glucocorticoid receptor-alpha mRNA, suggesting a hypocortisolemic state.

AB - INTRODUCTION: Indoleamine 2,3-dioxygenase 1 (IDO1) is overexpressed by cancer cells and the antigen presenting dendritic cells in the tumor microenvironment (TME). Activation of IDO1 depletes tryptophan and produces kynurenine, which induces T cell anergy and suppresses tumor control by the immune system. When combined with an immune checkpoint inhibitor, IDO1 inhibitors have shown promising anticancer activity in preclinical tumor models as well as in early stage clinical trials. Areas covered: IDO1 inhibitors disclosed in the patent literature from 2013-2017 are categorized, when applicable, according to their structural similarity to the clinical development candidates indoximod and PF 06840003, navoximod, epacadostat, KHK2455 and aryl-1,2-diamines, and BMS-986205 among others, respectively. Representative structures and their IDO1 inhibitory activity are presented to highlight the novelty and activity. Finally, the reported cocrystal structures were analyzed to provide insights for inhibitor enzyme interactions and guidance for the design and discovery of next generation inhibitors. Expert opinion: This review demonstrates that the structural diversity of new IDO1 inhibitors could be expanded via a number of approaches. PMID- 29473429 TI - A safety evaluation of budesonide MMX for the treatment of ulcerative colitis. AB - INTRODUCTION: Budesonide belongs to low-bioavailability steroids class. A novel oral formulation of budesonide, which uses the Multi-Matrix System (MMX) for delivering drugs to the colon, is now available as a possible treatment of ulcerative colitis patients intolerant or not-responding to first-line therapy with 5-ASA. Areas covered: in this review we present information about the development and the use of budesonide MMX and we provide data about its mechanism of action as well as, pharmacodynamics and pharmacokynetics. Moreover, we present the available literature data about the efficacy and, mainly, the safety of budesonide-MMX. Expert opinion: budesonide-MMX is a new therapeutic option in mild-to-moderate UC patients. Its good safety profile in clinical trials undoubtedly represents a strength for a possible wide use in clinical practice, mainly if it will be confirmed by post-marketing data. Other indications, such as treatment of colonic Crohn's disease, could theoretically be considered, if sustained by reliable scientific data.

AB - Dysregulation of the histone methyltransferase EZH2 plays a critical role in the development of a variety of malignancies including B-cell lymphomas. As a result, a series of small molecule inhibitors of EZH2 have been developed and studied in the pre-clinical setting. Three EZH2 inhibitors: tazemetostat (EPZ-6438), GSK2816126 and CPI-1205 have moved into phase I/phase II clinical trials in patients with non-Hodgkin lymphoma and genetically defined solid tumors. Early data from the tazemetostat trials indicate an acceptable safety profile and early signs of activity in diffuse large B-cell lymphoma and follicular lymphoma, including patients with EZH2 wild-type and mutant tumors. In this review, we present the rationale, key pre-clinical and early clinical findings of small molecule EZH2 inhibitors for use in lymphoma as well as future challenges and potential opportunities for combination therapies.

PMID- 29473432 TI - Human neutrophil lipocalin (HNL) as a biomarker of acute infections. AB - The early and accurate discrimination between bacterial and viral causes of acute infections is the key to a better use of antibiotics and will help slow down the fast-growing resistance to commonly used antibiotics. This discrimination is in the vast majority of cases possible to achieve by blood assay of the biomarker human neutrophil lipocalin (HNL), which we showed to be uniquely increased in patients suffering from bacterial infections. In serum, sensitivities and specificities of >90% are achieved in both adults and children. In order to eliminate the need to produce serum, a whole-blood assay with an assay time of <10 min was developed in which blood neutrophils are activated to release HNL. The diagnostic accuracy of this assay also showed sensitivities and specificities of >90% in most infectious diseases and was clearly superior to contemporary assays such as blood neutrophil counts, C-reactive protein, procalcitonin, and expression of CD64 on blood neutrophils. This format lends itself to the development of a point-of-care HNL assay and will be a major step forward to accomplish the goal of accurately diagnosing patients with symptoms of acute infections within 10 min at the emergency room or at the doctor's office. PMID- 29473434 TI - 4-Methylcatechol stimulates apoptosis and reduces insulin secretion by decreasing betacellulin and inhibin beta-A in INS-1 beta-cells. AB - Insulinoma INS-1 cell line is a pancreatic beta cell tumor which is characterized with high insulin content and secretion in response to increasing glucose levels. 4-Methylcatechol (4-MC) is a metabolite of quercetin, which is known as a potential drug for inhibition of tumorigenesis. The aim of this study was to determine the applying doses of 4-methylcatechol (4-MC) for triggening cell death and decreasing the cell function of rat insulinoma INS-1 beta cells. The rate of apoptosis and the amount of insulin in the cell and the secretions were determined by the ELISA method. Betacellulin (BTC) and inhibin beta-A amounts in both the cell and the glucose induced secretion were investigated by Western blotting. Furthermore, BTC, Inhibin beta-A, Ins1, Ins2, and GLUT2 gene expression levels were determined by the by the real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) method. We noted a significant decrease in cell viability, while an increase in apoptotic cell death by 4-MC treatment. It caused a decrease in the secretion of BTC, expressions of both BTC and inhibin beta-A. We showed a decrease in the expressions of Ins1 and GLUT2, while there is no alteration in the level of insulin protein. Insulin secretion levels increased in INS-1 cells given 4-MC by basal glucose concentration while they did not response to high concentration of glucose, which indicates that 4-MC disrupts the functionality of INS-1 cells. These results revealed that 4-MC induces apoptosis and decreases insulin secretion by reducing BTC and inhibin beta-A in insulinoma INS-1 cells. Thus, 4-MC may be offered as a potential molecule for treatment of insulinoma. PMID- 29473435 TI - A new neolignan from the thorns of Gleditsia japonica var. delavayi.

AB - One new triterpenoid saponin (1), as well as six known ones (2-7), were isolated from the ethanol extract of the thorns of Gleditsia sinensis. Their structures were elucidated by extensive spectroscopic analysis in conjunction with chemical evidence. Cytotoxic activity of compounds 1-6 was evaluated against human breast cancer MCF 7 cells in vitro by the MTT method. Our results revealed moderate activities for compounds 1-6 with IC50 values of 18.43, 30.47, 18.46, 10.02, 30.76, and 17.32 MUM, respectively. Furthermore, compounds 1, 3, 4, and 6 induced apoptosis in MCF 7 cell, with 1 and 6 causing late apoptosis of MCF 7 cells, while 3 and 4 acting oppositely. PMID- 29473438 TI - CRISPR and personalized Treg therapy: new insights into the treatment of rheumatoid arthritis. AB - INTRODUCTION: Rheumatoid arthritis (RA), as one of the most disabling autoimmune diseases, is a common health problem that progressively reduces the life quality of patients. Although various biologics have been introduced for RA, attempts to establish an efficient long-term therapies failed due to the heterogeneity of this disease. METHODS: In the last decade, immunomodulatory approaches such as T cell adoptive therapy have been developed for controlling autoimmunity. Regulatory T cells (Tregs), the major self-tolerance mediator, are crucial for down-regulation of aberrant immune stimulations. Hence, recruiting ex vivo Tregs emerged as a promising therapy for a variety of autoimmune diseases. RESULTS: The major bottleneck of the Treg adoptive therapy is maintaining the in vivo stability and plasticity of these fascinating cells. Recent progress in genome editing technology clustered regularly interspaced short palindromic repeats (CRISPR) in combination with CRISPR-associated (Cas) 9 system provided a new solution for this bottleneck. CONCLUSIONS: The present paper discusses RA pathogenesis and the potential application of new developments in CRISPR-mediated Treg genome editing in personalized therapy of RA. PMID- 29473439 TI - Welfare State Replacements: Deinstitutionalization, Privatization and the Outsourcing to Immigrant Women Enterprise. AB - The U.S. government has a long tradition of providing direct care services to many of its most vulnerable citizens through market-based solutions and subsidized private entities. The privatized welfare state has led to the continued displacement of some of our most disenfranchised groups in need of long term care. Situated after the U.S. deinstitutionalization era, this is the first study to examine how immigrant Filipino women emerged as owners of de facto mental health care facilities that cater to the displaced, impoverished, severely mentally ill population. These immigrant women-owned businesses serve as welfare state replacements, overseeing the health and illness of these individuals by providing housing, custodial care, and medical services after the massive closure of state mental hospitals that occurred between 1955 and 1980. This study explains the onset of these businesses and the challenges that one immigrant group faces as owners, the meanings of care associated with their de facto mental health care enterprises, and the conditions under which they have operated for more than 40 years. PMID- 29473440 TI - Goal setting in paediatric rehabilitation for children with motor disabilities: a scoping review. AB - OBJECTIVES: The three objectives of this scoping review were to (1) identify key conceptual/theoretical frameworks and the extent to which they are used to inform goal setting related to rehabilitation goal setting with children with motor disabilities, (2) describe research that has evaluated goal setting processes and outcomes, and (3) summarize the purposes of goal setting described in paediatric rehabilitation literature. METHODS: The scoping review process described by Arksey and O'Malley was used to guide article selection and data extraction. RESULTS: A total of 62 articles were included in the final review. While the concept of family-centered care was well represented, theoretical frameworks specific to goal setting (i.e. goal setting theory described by Locke and Latham, mastery motivation, social cognitive, personal construct, and self-determination theories) were rarely addressed. No articles reviewed addressed prominent behavior change theory. With the exception of the description of tools specifically designed for use with children, the role of the child in the goal setting process was generally absent or not well described. Few studies ( n = 6) discussed the linkage between goals and intervention strategies explicitly. Only two studies in the review evaluated outcomes associated with goal setting. The primary purpose for goal setting identified in the literature was to develop goals that are meaningful to families ( n = 49). CONCLUSION: The results highlight significant gaps in the literature explicating a sound theoretical basis for goal setting in paediatric rehabilitation and research evaluating the effects of goal qualities and goal setting processes on the achievement of meaningful outcomes. PMID- 29473441 TI - Item analysis of the Spanish version of the Boston Naming Test with a Spanish speaking adult population from Colombia. AB - OBJECTIVE: The Boston Naming Test (BNT) is a widely used measure of confrontation naming ability that has been criticized for its questionable construct validity for non-English speakers. This study investigated item difficulty and construct validity of the Spanish version of the BNT to assess cultural and linguistic impact on performance. METHODS: Subjects were 1298 healthy Spanish speaking adults from Colombia. They were administered the 60- and 15-item Spanish version of the BNT. A Rasch analysis was computed to assess dimensionality, item hierarchy, targeting, reliability, and item fit. RESULTS: Both versions of the BNT satisfied requirements for unidimensionality. Although internal consistency was excellent for the 60-item BNT, order of difficulty did not increase consistently with item number and there were a number of items that did not fit the Rasch model. For the 15-item BNT, a total of 5 items changed position on the item hierarchy with 7 poor fitting items. Internal consistency was acceptable. CONCLUSIONS: Construct validity of the BNT remains a concern when it is administered to non-English speaking populations. Similar to previous findings, the order of item presentation did not correspond with increasing item difficulty, and both versions were inadequate at assessing high naming ability. PMID- 29473443 TI - Pesticide Use, Poisoning, and Knowledge and Unsafe Occupational Practices in Thailand. AB - The agricultural system in Thailand has shifted from a traditional to a commercial agricultural system. Pesticides have been imported into Thailand to increase agricultural productivity, resulting in adverse health effects for farmers and consumers. However, the scientific data available in Thailand are limited and inconsistent. Thus, this article reviews research studies regarding pesticide use, poisoning, and knowledge and unsafe occupational practices in Thailand over the last decade. This article also makes recommendations for future policies. Research studies conducted in Thailand during 2006-2017 were reviewed and summarized. Overall, there are several solutions to address the pesticide problem, such as rigorous legislation and regulations, campaigns for reducing pesticide use, education, and training. The Thai government has an important role in making policies and regulations and encouraging all agricultural activities to be sustainable. PMID- 29473444 TI - Bad is Stronger Than Good for Stigmatized, but Not Admired Outgroups: Meta Analytical Tests of Intergroup Valence Asymmetry in Individual-to-Group Generalization Experiments. AB - Theories of risk aversion, epistemic defense, and ingroup enhancement converge in predicting greater impact of negative (vs. positive) experiences with outgroup members on generalized evaluations of stigmatized outgroups. However, they diverge in predictions for admired outgroups. Past tests have focused on negative outgroups using correlational designs without a control group. Consequently, they have not distinguished between alternative explanations or ascertained the direction of causality/generalization, and they have suffered from self-selection biases. These limitations were redressed by a meta-analysis of experimental research on individual-to-group generalization with positive and negative outgroups (59 tests; 3,012 participants). Controlling for modest confounds, the meta-analysis found a generalization advantage of negative experiences for stigmatized outgroups and a generalization advantage of positive experiences for admired outgroups. These results highlight the centrality of valenced expectations about outgroups, consistent with epistemic defense and ingroup enhancement and inconsistent with risk aversion. Implications for positive changes in intergroup dynamics are discussed. PMID- 29473442 TI - HU protein is involved in intracellular growth and full virulence of Francisella tularensis. AB - The nucleoid-associated HU proteins are small abundant DNA-binding proteins in bacterial cell which play an important role in the initiation of DNA replication, cell division, SOS response, control of gene expression and recombination. HU proteins bind to double stranded DNA non-specifically, but they exhibit high affinity to abnormal DNA structures as four-way junctions, gaps or nicks, which are generated during DNA damage. In many pathogens HU proteins regulate expression of genes involved in metabolism and virulence. Here, we show that the Francisella tularensis subsp. holarctica gene locus FTS_0886 codes for functional HU protein which is essential for full Francisella virulence and its resistance to oxidative stress. Further, our results demonstrate that the recombinant FtHU protein binds to double stranded DNA and protects it against free hydroxyl radicals generated via Fenton's reaction. Eventually, using an iTRAQ approach we identified proteins levels of which are affected by the deletion of hupB, among them for example Francisella pathogenicity island (FPI) proteins. The pleiotropic role of HU protein classifies it as a potential target for the development of therapeutics against tularemia. PMID- 29473445 TI - The determination of monomers and oligomers from polyester-based can coatings into foodstuffs over extended storage periods. AB - The polymeric coating used in metal packaging such as cans for foods and beverages may contain residual amounts of monomers used in the production of the coating, as well as unreacted linear and cyclic oligomers. Traditionally, although designed for use with plastic food contact materials, food simulants have been used to determine the migration of monomers from coatings into foodstuffs. More recently, food simulants have also been used to determine oligomeric species migrating from can coatings. In the work reported here, the migration of both monomers and oligomers from polyester-based can coatings into food simulants and foodstuffs, some of which were towards the end of their shelf life, is compared. The concentrations of monomers and selected oligomers in canned foods at the end of their shelf life were found to be significantly lower than those in food simulants, which in turn was lower than those in the extraction solvent acetonitrile. PMID- 29473446 TI - Predicting shoulder function after constraint-induced movement therapy: a retrospective cohort study. AB - Background Several predictors have been associated with upper extremity (UE) recovery after stroke, but characteristics that predict shoulder function after constraint-induced movement therapy (CIMT) have not yet been identified. Objectives To identify predictors associated with satisfactory shoulder function in patients with reduced shoulder function at admission to CIMT. Methods One hundred and seventy five patients were treated using CIMT while in a specialized inpatient hospital. Satisfactory shoulder function was defined according to the functional ability scale of the Wolf Motor Function test. Predictors of satisfactory shoulder function after CIMT were identified using multivariable logistic regression. Results Better distal arm function and good proximal shoulder function on admission to CIMT were strong predictors of satisfactory shoulder function, while age and time of admission to CIMT since stroke were not. Seventeen percent of all CIMT-participants with reduced shoulder function pre CIMT reached a level of satisfactory shoulder function after CIMT. Discussion A substantial part of patients with reduced shoulder function reached a level of satisfactory shoulder function after CIMT. Intensive CIMT training, comprising tasks that require both distal and proximal UE function, may increase shoulder function in patients with a potential functional reserve. PMID- 29473447 TI - U0126 protects hippocampal CA1 neurons against forebrain ischemia-induced apoptosis via the ERK1/2 signaling pathway and NMDA receptors. AB - OBJECTIVE: Cerebral ischemia can trigger the ERK1/2 signaling cascade that enables the brain to adapt to ischemic injury. However, the mechanism of ERK1/2 in ischemic brain injury remains unclear. The aim of this study was to examine the roles of the ERK1/2 signaling pathway and NMDA receptors in the apoptosis of CA1 pyramidal neurons after ischemia/reperfusion (I/R). METHODS: Male Wistar rats were subjected to a sham or transient forebrain ischemia procedure. Animals received the intracerebroventricular injection of U0126 (5 MUl, 0.2 MUg/MUl) or vehicle 30 min before ischemia. Homogenates of the hippocampal CA1 field were obtained from sham-operated and ischemic rats 6, 12 or 48 h after ischemia/reperfusion (n = 6 per group) and then subjected to Western blotting analysis and TUNEL staining. Caspase-3 activity was assayed with a colorimetric assay kit. RESULTS: We found that the phosphorylation level of ERK1/2 is increased in the CA1 region following transient I/R. Blocking the ERK1/2 signaling pathway by administration U0126 attenuated apoptotic neuronal cell death via inhibition of NMDA receptors. CONCLUSION: These findings suggest a novel mechanism by which the ERK1/2 signaling pathway affects the post-I/R apoptosis of CA1 pyramidal neurons, which will provide a therapeutic target for the treatment of stroke. PMID- 29473448 TI - Demographic and clinical features do not affect the outcome of combined endovenous therapy to treat leg swelling. AB - Background There have been well-documented implications of race/ethnicity on the outcome of various vascular diseases, yet there are limited data on risk factors and outcome of lower limb swelling. While many patients improve with endovenous therapy (thermal ablation or iliac vein stenting), some patients' symptoms persist. The goal of this study was to identify clinical factors including race/ethnicity related to persistent leg swelling after treatment with both iliac vein stenting and thermal ablation. Methods From February 2012 to February 2014, this observational study analyzed data for 173 patients with chronic venous insufficiency who underwent both iliac vein stent placement as well as thermal ablation (radiofrequency ablation or endovenous laser ablation). All procedures of the thermal ablations and the iliac vein stenting were staged. Iliac vein stenosis was identified using intravascular ultrasound of the iliofemoral venous segment showing >50% cross-sectional area or diameter reduction. The patients were queried to the resolution of their leg swelling after both procedures were performed. The resolution of swelling was correlated with age, gender, presenting sign according to CEAP classification, race/ethnicity and degree of iliac vein stenosis. Patients were categorized by Caucasians ( n = 97), African Americans ( n = 27), or Hispanics ( n = 49). Statistical analysis performed using Chi-square and Student's t test. Results Of the total 173 patients who underwent both endovenous closure and iliac vein stent placements, 117 (67.6%) patients were women. The average age was 67 (+/-13 SD) years. The average pain score was 2.9(+/ 3.1 SD). The average degree of iliac vein stenosis was 66.5(+/-13.3 SD). About 56.1% were Caucasians, 15.6% were African Americans, and 28.3% were Hispanics. The number of patients with iliac vein stent thrombosis was 2. One hundred fifty two (87.9%) patients stated that they had improvement in swelling after combined procedures, 100 (65.8%) patients were women. The average age was 67.3 (+/-13 SD) years. The average pain score was 2.9 (+/-3.1 SD). The average degree of iliac vein stenosis was 67.3% (+/-12.8 SD). About 56.6% were Caucasians, 15.1% were African Americans, and 28.3% were Hispanics. The number of patients with iliac vein stent thrombosis was 1. Twenty-one (12.1%) patients stated they had no improvement after both procedures. Correlating these group factors with the group of patients who improved their swelling after the combined procedures we found the following: 17 (81%) of these patients were females ( P=0.16). The average age was 68.4 (+/-17 SD) years ( P=0.72 SD). The average pain score was 3.2 (+/-3.7 SD) ( P=0.68). The average degree of iliac vein stenosis was 60.2% (+/-15.9 SD) ( P=0.02). Around 52.4% were Caucasians, 19% were African Americans, and 28.6% were Hispanics ( P=0.88). The number of patients with iliac vein stent thrombosis was 1 ( P = 0.1). Conclusion These data suggest that the clinical factors including race are not clinically significant factors in the response to swelling after combined iliac stent and endovenous ablation procedures. Interestingly, a higher degree of iliac vein stenosis was associated with improved resolution of swelling. PMID- 29473449 TI - Aspirin use is associated with decreased radiologically-determined thrombus sac volume in abdominal aortic aneurysms. AB - Introduction Formation and renewal of intramural thrombus is associated with inflammation, and contributes to the complexity of aneurysm repair. Current cardiovascular pharmacotherapy includes several inflammatory modulators such as aspirin, statins, clopidogrel, and angiotensin-converting enzyme inhibitors. The purpose of our study was to investigate the effect of these inflammatory modulators on radiographically-determined thrombus sac volume. Methods Pre operative computed tomography scans were reviewed in patients who underwent elective infrarenal aortic aneurysm repair. Thrombus sac volume was obtained using a Hounsfield unit restricted region growth algorithm. Co-morbid conditions such as diabetes mellitus and post-operative complications were evaluated compared to thrombus sac volume. Receiver-operator characteristic curves were generated for thrombus sac volume and patients on the various cardiovascular pharmacotherapies. Results A total of 266 patients (mean age = 72.6 +/- 0.6 years; mean thrombus sac volume = 58.7 (34.4-89.0) cm3) were identified. Acetylsalicylic acid use was associated with a decreased thrombus sac volume <=50 cm3 (AUC = 0.616, p = 0.013) whereas statins ( p = 0.26), angiotensin-converting enzyme inhibitors ( p = 0.46), and clopidogrel ( p = 0.62) had no correlation to thrombus sac volume. Diabetes mellitus was not associated with thrombus sac volume ( p = 0.31). Conclusion Acetylsalicylic acid use is associated with decreased thrombus sac volume in a patient population undergoing elective abdominal aortic aneurysms repair. The effect of acetylsalicylic acid over other anti-inflammatory and anti-platelet agents is possibly attributable to its distinct mechanism of cyclooxygenase-1 inhibition. Diabetes mellitus, a known correlate of aneurysm incidence, is not associated with thrombus burden. The potential to alter aneurysm thrombus volume, thereby affecting aneurysm morphology, may yield a more favorable aneurysmal repair.

AB - The theoretical five-factor model for the 35-item Beliefs About Language Learning Inventory (BALLI) has rarely been examined empirically, despite its wide use to investigate language learning beliefs. This study examined the BALLI's dimensional structure with a sample of undergraduate students at a Thai university ( N = 537; male 43.4%, female 56.4%; age mean = 19.12 years), taking an elementary-level Japanese language course. Confirmatory factor analysis by M plus did not support Horwitz's theoretical model. While a five-factor model was identified from exploratory factor analysis, the combined items within each dimension were different from Horwitz's model. Thus, the original five-factor BALLI model was only partially supported. We were able to affirm the core aspects of language learning beliefs composed of eight BALLI items, and we offer a roadmap to develop the model. PMID- 29473451 TI - A nationwide cross-sectional survey of pharmacy students on pharmacogenetic testing in The Netherlands. AB - AIM: To benchmark knowledge and attitude of pharmacy students toward pharmacogenetics (PGx) and PGx testing and compare the results with practicing colleagues. METHODS: All pharmacy students in The Netherlands were invited to participate in a web-based survey consisting of 28 questions. Out of the 824 invited students, 148 individuals (18.0%) completed the questionnaire. All responders believed in the concept of PGx and had high expectations toward PGx. The majority (96.6%) had received some form of education on PGx, but only 12.8% felt adequately informed. RESULTS: When compared with practicing pharmacists, differences were observed in the use of information and feeling qualified to recommend PGx testing. CONCLUSION: More education on PGx is required in the curriculum to fill the perceived knowledge gap among future pharmacists. PMID- 29473452 TI - A New Surgical Device for Anterograde Intraoperative Rectal Washout. AB - BACKGROUND: Colorectal cancer is the fourth most diffuse cause of death in the world and local recurrence is associated with a reduced long-term life expectancy, with a reduced quality of life. Rectal washout at the anastomosis site leads to a statistically significant reduction of local recurrences. METHODS: We developed the idea of a new laparoscopic stapler with an integrated washout system that could decontaminate the rectal stump before resection, without the need to enlarge the standard surgical incision or even to distort the incision site, closing the rectal stump just below the inferior part of the cancer, and then proceeding with the resection and stapling of the distal part of the tumor. Combined with these canonical functionalities, the new device, equipped with a patented washout system (patent number EP 3103401A1) will also allow to inject in the closed bowel a physiologic saline liquid. RESULTS: In force of the mechanical action of the liquid injected, carcinogenic exfoliated cells eventually floating in the affected region of the colonic lumen will be expelled through the anal orifice. The intraoperative rectal washout, both in minimally invasive and in traditional open surgery, thus becomes a simple, effective, and reproducible procedure. CONCLUSIONS: We describe the technical features and the possible clinical applications of a potentially new surgical laparoscopic stapler coupled with an integrated irrigation system. We have patented the system and we are developing a prototype with the aim to start an experimental pilot study.

AB - Wilhelm Fabricius von Hilden (1560-1634) or also known with his Latinized name Guilielmus Fabricius Hildanus is considered the founder of scientific German surgery. He introduced new surgical techniques and invented new surgical instruments for the surgical treatment of nasal polyps, stone bladder, breast and ocular cancer, hydrocele, and ascites, while very ingenious were his amputation techniques. His most important surgical treatise was Observationem et curationem chirurgicam centuriae sex ( Six Hundred Surgical Observations and Treatments) first published in 1606. PMID- 29473454 TI - Correction of radiographic measurements of acetabular cup wear for variations in pelvis orientation. AB - Radiographic measurement of two-dimensional acetabular cup wear is usually carried out on a series of follow-up radiographs of the patient's pelvis. Since the orientation of the pelvis might not be consistent at every X-ray examination, the resulting change in view of the wear plane introduces error into the linear wear measurement. This effect is amplified on some designs of cup in which the centre of the socket is several millimetres below the centre of the cup or circular wire marker. This study describes the formulation of a mathematical method to correct radiographic wear measurements for changes in pelvis orientation. A mathematical simulation of changes in cup orientation and wear vectors caused by pelvic tilt was used to confirm that the formulae corrected the wear exactly if the radiographic plane of the reference radiograph was parallel to the true plane of wear. An error analysis showed that even when the true wear plane was not parallel to the reference radiographic plane, the formulae could still provide a useful correction. A published correction formula was found to be ineffective. PMID- 29473455 TI - Sagittal flexion arc evaluation for a modern generation single-radius femoral component design. AB - Single-radius femoral total knee design aims to deliver improved kinematic behaviour when compared to the standard two-radii geometry. This study has evaluated the behaviour, through a functional range of motion in the sagittal plane, of a single-radius femoral component compared to a dual-radius standard knee construct. Particular focus was placed on how the flexion axes of the native and replaced knee approximated to the transepicondylar axis through a loaded navigated knee design. Significant differences in flexion arcs were noted between the native and total knee arthroplasty state. These arcs were not uniform in all knees and did not display single-radius behaviour. There were no significant differences in the location of flexion axes in the native and total knee arthroplasty knee. Both exhibited similar posterior and inferior transverse axes of motion with respect to the anatomical epicondylar axis. This work has cast doubt on the reliability under loaded conditions of the single-radius concept, but the close proximity of the flexion axes of each replaced knee in relation to the functional flexion axis of the native knee may be the true basis of this purported improved kinematic performance. PMID- 29473456 TI - Peripheral somatosensory stimulation and postural recovery after stroke - a systematic review. AB - Purpose It is hypothesized that peripheral somatosensory stimulation (PSS) can promote postural recovery after stroke by increasing afferent input and postural contribution of the paretic leg. Therefore, this systematic review aims to investigate which PSS approaches are documented and investigated on effectiveness. Methods Five databases (PubMed, Web of Science, PEDro, Cochrane Library Trials, RehabData) have been searched on clinical studies in stroke rehabilitation, investigating PSS, which is defined as a non-motor and focal stimulation to the paretic leg aiming an increase in somatosensory input. Results Twenty studies present different PSS approaches (mainly electrical and vibration stimulation) and following results: (I) There is an immediate effect after a single session of PSS on postural stability. In contrast, (II) repetitive sessions of isolated PSS led to highly inconsistent results. Finally, (III) PSS as an adjuvant to exercises did promote long-term postural recovery. Conclusion PSS is found to be effective immediately and on a long-term as an adjuvant therapy only in improving postural stability in a chronic stroke population. However, if PSS enhances paretic leg postural contribution remains unclear. Future research is warranted considering promising results and high prevalence of postural instability impacting daily life of stroke survivors. PMID- 29473458 TI - Hyperbaric oxygen as an adjuvant to temozolomide nanoparticle inhibits glioma growth by inducing G2/M phase arrest. AB - AIM: To study the effects of combinational treatment of hyperbaric oxygen (HBO) and nanotemozolomide in glioma. MATERIALS & METHODS: Temozolomide (TMZ)-loaded porous silicon nanoparticles (TMZ/PSi NPs) were prepared. In vitro and in vivo evaluations were performed. RESULTS: The cell uptake of TMZ/PSi NPs could be tracked by autofluorescence of porous silicon. The concentration of oxygen in tumor was improved and the antitumor rate was increased to 84.2% in the TMZ/PSi NPs combined with HBO group. The viability of hypoxia-induced glioma C6 cells was decreased and cell cycle was arrested at G2/M phase in response to TMZ/PSi NPs treatment with HBO compared with continuous treatment with hypoxia. CONCLUSION: The combinational treatment of TMZ/PSi NPs and HBO could be a promising therapeutic strategy for glioma. PMID- 29473459 TI - Safety I-II, resilience and antifragility engineering: a debate explained through an accident occurring on a mobile elevating work platform. AB - Occupational health and safety (OHS) represents an important field of exploration for the research community: in spite of the growth of technological innovations, the increasing complexity of systems involves critical issues in terms of degradation of the safety levels. In such a situation, new safety management approaches are now mandatory in order to face the safety implications of the current technological evolutions. Along these lines, performing risk-based analysis alone seems not to be enough anymore. The evaluation of robustness, antifragility and resilience of a socio-technical system is now indispensable in order to face unforeseen events. This article will briefly introduce the topics of Safety I and Safety II, resilience engineering and antifragility engineering, explaining correlations, overlapping aspects and synergies. Secondly, the article will discuss the applications of those paradigms to a real accident, highlighting how they can challenge, stimulate and inspire research for improving OHS conditions. PMID- 29473457 TI - An ecoimmunological approach to study evolutionary and ancient links between coagulation, complement and Innate immunity. AB - Coagulation, complement, and innate immunity are tightly interwoven and form an alliance that can be traced back to early eukaryotic evolution. Here we employed an ecoimmunological approach using Tissue Factor Pathway Inhibitor (TFPI)-1 derived peptides from the different classes of vertebrates (i.e. fish, reptile, bird, and mammals) and tested whether they can boost killing of various human bacterial pathogens in plasma. We found signs of species-specific conservation and diversification during evolution in these peptides that significantly impact their antibacterial activity. Though all peptides tested executed bactericidal activity in mammalian plasma (with the exception of rodents), no killing was observed in plasma from birds, reptiles, and fish, pointing to a crucial role for the classical pathway of the complement system. We also observed an interference of these peptides with the human intrinsic pathway of coagulation though, unlike complement activation, this mechanism appears not to be evolutionary conserved. PMID- 29473460 TI - Global frameworks, local strategies: Women's rights, health, and the tobacco control movement in Argentina. AB - The article examines how civil society organisations in Argentina used the United Nations Convention on the Elimination of All Forms of Discrimination Against Women (CEDAW) to frame the country's failure to enact strong national tobacco control legislation as a violation of women's rights in the late 2000s. We analyze this case study through the politics of scale, namely the social processes that produce, reproduce, and contest the boundaries of policies and socio-economic relations. This approach understands how multiple scales overlap and connect to obstruct or enhance the right to health in Latin America. In Argentina, the global organisation of tobacco companies, the reach of international financial institutions and the national dynamics of economic austerity and export-orientation promoted the local production and use of tobacco (leaf and cigarettes) and reproduced health inequalities in the country throughout the 1990s and the early 2000s. Yet, the visible legacy of local and national human rights struggles in the adoption of international human rights treaties into Argentina's national constitution allowed the tobacco control movement to link the scale of women's bodies to the right to health through the use of CEDAW to change national legislation, tackling the social determinants of the tobacco epidemic. PMID- 29473461 TI - Primary aldosteronism and thyroid disorders in atrial fibrillation: A Swedish nationwide case-control study. AB - Background Atrial fibrillation is associated with hyperthyroidism. Patients with primary aldosteronism have an increased prevalence of atrial fibrillation. However, the prevalence of primary aldosteronism in the atrial fibrillation population is unknown. Aim This nationwide case-control study aimed to compare the prevalence of primary aldosteronism and thyroid disorders in patients with atrial fibrillation with that of age- and sex-matched controls. Methods We identified all atrial fibrillation cases in Sweden between 1987 and 2013 ( n = 713,569) by using the Swedish National Patient Register. A control cohort without atrial fibrillation was randomly selected from the Swedish Total Population Register with a case to control ratio of 1:2. This control cohort was matched for age, sex and place of birth ( n = 1,393,953). Results The prevalence of primary aldosteronism in December 2013 was 0.056% in the atrial fibrillation cohort and 0.024% in controls. At the same time, the prevalence of hypothyroidism was 5.9% in the atrial fibrillation cohort and 3.7% in controls. The prevalence of hyperthyroidism was 2.3% in the atrial fibrillation cohort and 0.8% in controls. Conclusion This study shows, for the first time, a doubled prevalence of primary aldosteronism in a large cohort of patients with atrial fibrillation compared with the general population. There is also an increased prevalence of hypo- and hyper-thyroidism in patients with atrial fibrillation compared with the general population. PMID- 29473462 TI - Association of serum potassium concentration with mortality and ventricular arrhythmias in patients with acute myocardial infarction: A systematic review and meta-analysis. AB - Background Challenging clinical practice guidelines that recommend serum potassium concentration between 4.0-5.0 mEq/L or >=4.5 mEq/L in patients with acute myocardial infarction, recent studies found increased mortality risks in patients with a serum potassium concentration of >=4.5 mEq/L. Studies investigating consequences of hypokalemia after acute myocardial infarction revealed conflicting results. Therefore, the aim of this systematic review and meta-analysis was to combine evidence from previous studies on the association of serum potassium concentration with both short and long-term mortality as well as the occurrence of ventricular arrhythmias. Design Systematic review and meta analysis. Methods A structured search of MEDLINE and EMBASE databases yielded 23 articles published between 1990 and January 2017 that met the inclusion criteria. Study selection, data extraction and quality assessment were carried out by three reviewers. Random effects models were used to pool estimates across the included studies and sensitivity analyses were performed when possible. Results Twelve studies were included in the meta-analysis. Both pooled results from six studies investigating short-term mortality and from five studies examining long-term mortality revealed significantly increased risks in patients with serum potassium concentrations of <3.5 mEq/L, 4.5-<5.0 mEq/L and >=5.0 mEq/L after acute myocardial infarction. In addition, a serum potassium concentration of <3.5 mEq/L was significantly associated with the occurrence of ventricular arrhythmias. Conclusions Mortality, both short and long term, and the occurrence of ventricular arrhythmias in patients with acute myocardial infarction seem to be negatively associated with hypokalemic serum potassium concentration. There is evidence for adverse consequences of serum potassium concentrations of >=4.5 mEq/L. Due to the heterogeneity among existing studies, further research is necessary to confirm the need to change clinical practice guidelines. PMID- 29473463 TI - Markers of neutrophil extracellular traps are associated with adverse clinical outcome in stable coronary artery disease. AB - Background Neutrophil extracellular traps, comprising chromatin and granule proteins, have been implicated in atherothrombosis. Design and methods We investigated whether the circulating neutrophil extracellular traps markers, double-stranded DNA and myeloperoxidase-DNA were associated with clinical outcome and hypercoagulability in patients with stable coronary artery disease. Patients with angiographically verified stable coronary artery disease ( n = 1001) were included. Follow-up was 2 years, recording 106 clinical endpoints (unstable angina, non-haemorrhagic stroke, myocardial infarction or death). Serum collected at baseline was used to determine double-stranded DNA and myeloperoxidase-DNA levels. Results The neutrophil extracellular traps markers were weakly intercorrelated ( r = 0.103, P = 0.001). Patients with the highest quartile of double-stranded DNA had weakly but significantly elevated hypercoagulability markers (prothrombin fragment 1+2, D-dimer, free and total tissue factor pathway inhibitor ( P < 0.001 for all)). Men, smokers, patients with metabolic syndrome and patients with a previous myocardial infarction had significantly elevated double-stranded DNA levels ( P <= 0.002 for all). Significantly higher double stranded DNA levels were observed in the group experiencing a clinical endpoint compared to the group without ( P = 0.019). When categorising double-stranded DNA into quartiles, a distinct cut-off between the lowest and upper three quartiles was observed. Adjusting for relevant covariates, patients in the upper three quartiles had an odds ratio of 2.01 (95% confidence interval 1.12, 3.58, P = 0.019) for experiencing a clinical endpoint. Myeloperoxidase-DNA was not significantly associated with clinical outcome or hypercoagulability. Conclusions Double-stranded DNA levels were significantly related to adverse clinical outcome after 2 years, but only weakly associated with hypercoagulability. These observations suggest that the detrimental effects of neutrophil extracellular traps in coronary artery disease might extend beyond those related to hypercoagulability.

PMID- 29473467 TI - Checkpoint inhibitors: 'raising the bar' also in brain metastases from non-small cell lung cancer? AB - Despite efforts, brain metastases (BM) remain a critical issue in the management of patients affected by non-small-cell lung cancer (NSCLC). To date, radiotherapy is still considered the gold standard treatment; on the other hand, systemic chemotherapeutical agents are not so often an effective therapy for BM, whereas targeted agents in oncogene-addicted disease have shown a good activity also on BM. Anti-programmed death-1/programmed death ligand-1 agents represent a new valid therapeutic strategy for NSCLC as well as for several tumor types, but their efficacy on patients with BM is still unclear mainly due to the strict selection criteria adopted in clinical trials. The aim of the present article is to discuss the potential activity of checkpoint inhibitors in patients with BM from NSCLC. PMID- 29473468 TI - Is it possible to rechallenge with PD-1/PD-L1 inhibitors after progression? PMID- 29473469 TI - Immunotherapy for thoracic oncology gone viral. AB - Immune therapy has now been incorporated into the standard of care for non-small cell lung cancer based on randomized trials showing superiority of anti-PD1 antibodies compared with chemotherapy. Thus there is a renewed interest in immune approaches to treating lung cancer. One promising approach is with oncolytic viruses that either naturally or through engineering, preferentially infect or kill cancer cells. In preclinical models of different thoracic cancers, it has been found that these viruses can induce immune responses through multiple mechanisms. Thus, in addition to their direct cytolytic effects, oncolytic viruses can also promote antitumor immunity. This review will discuss the immune effects of oncolytic viruses lung cancers and the approaches that are underway to augment immune therapy in clinical testing. PMID- 29473470 TI - Tumor lysate particle loaded dendritic cell vaccine: preclinical testing of a novel personalized cancer vaccine. AB - AIM: We developed a novel approach to efficiently deliver autologous tumor antigens to the cytoplasm of dendritic cells (DC) using yeast cell wall particles (YCWP). MATERIALS AND METHODS: Loading of YCWP, leakage of protein from loaded YCWP and cytoplasmic delivery of YCWP content was assessed using fluorescent tagged experiments. Spectrophotometric analysis compared the epitope-specific T cell responses following antigen presentation via YCWP versus exogenous loading. The in vivo effectiveness of tumor lysate (TL) particle loaded DC (TLPLDC) vaccine was assessed using murine melanoma models. RESULTS: In fluorescence tagged experiments, YCWP efficiently delivered antigen to the cytoplasm of DC. TLPLDC loading was more effective than conventional exogenous loading of DC. Finally, in murine melanoma models, TLPLDC outperformed an analogous dendritoma vaccine. CONCLUSION: The TLPLDC vaccine is commercially scalable and holds the potential of producing personalized vaccines. PMID- 29473471 TI - Malignant mesothelioma clinical trial combines immunotherapy drugs. AB - Immunotherapy by checkpoint inhibitor is effective for a number of solid tumors including malignant mesothelioma. Studies utilizing single-agent PD-1 or PD-L1 inhibitor for mesothelioma have reported tumor response rates in approximately 10 20% of patients treated. Given the success of combining these agents with CTLA-4 inhibitor in melanoma, there is a strong rationale to study it in mesothelioma. Recently results from clinical trials investigating this approach have been released. Though limited by small sample size, the studies conclusively demonstrated feasibility and suggested a modestly higher tumor response rate than one would expect from treatment with single-agent PD-1 or PD-L1 inhibitor. Nevertheless, toxicity was also increased. Immunotherapy-related deaths due to encephalitis, renal failure and hepatitis were observed. Further studies are warranted. PMID- 29473472 TI - Application of cancer-testis antigens in immunotherapy of hepatocellular carcinoma. AB - Hepatocellular carcinoma (HCC) is a worldwide common malignancy with poor prognosis. Several studies have aimed at identification of appropriate biomarkers for early detection of this cancer. Cancer-testis antigens (CTAs) as a novel group of tumor-associated antigens have been demonstrated to be expressed in HCC samples as well as peripheral blood samples from these patients but not in the corresponding adjacent noncancerous samples. Such pattern of expression has provided them an opportunity to be used as immunotherapeutic targets. The detection of spontaneous immune responses against CTAs in HCC patients has prompted design of CTA-based immunotherapeutic protocols in these patients. The results of some clinical trials have been promising in a subset of patients. PMID- 29473473 TI - Crisis of Meaning Predicts Suicidality in Youth Independently of Depression. AB - BACKGROUND: At times, the question for meaning comes to nothing and a crisis of meaning ensues. This state is very painful, but difficult to account. Both those who suffer from it and care professionals find themselves at a loss for words. AIMS: This study introduces an operationalization of a crisis of meaning. It aims to distinguish the concept from depression, and to investigate whether a crisis of meaning can explain suicidality beyond the known protective and risk factors self-esteem, family functioning, life-event load, and depression. METHOD: Final year school pupils in Ecuador (N = 300) completed questionnaires assessing the above variables. Data were analyzed using chi-square, hierarchic multiple regression, serial mediation, and moderator analyses. RESULTS: Crisis of meaning was distinguished from depression. It explained a significant amount of variance in suicidality beyond the mentioned protective and risk factors. For males, crisis of meaning was the only significant risk factor, and the strongest predictor overall. The acute risk factors depression and crisis of meaning mediated the effects of the baseline factors self-esteem, family functioning, and life-event load on suicidality. LIMITATIONS: The study was cross-sectional; assessed factors predicted variance in suicidal thoughts, plans, and past suicide attempts, while their relevance cannot be generalized to actual future suicide attempts. CONCLUSION: A crisis of meaning is an important factor to take into account in further research on the prevention and treatment of people at risk of suicide. PMID- 29473475 TI - Clinical Profiles Among Greek Adolescent Suicide Attempters. AB - BACKGROUND: Suicide attempts are a significant public health problem among youth, resulting in a major social and economic burden for communities and a devastating impact on families. AIMS: To determine whether we can identify distinct clinical profiles using latent class analysis in a clinical sample of Greek adolescents who were admitted to hospital following a suicide attempt. METHOD: Data on 11 clinical parameters from 182 adolescents were analyzed, with a two-class solution selected as the best fitting among the one- through three-class solutions that were examined. RESULTS: We observed two distinct classes, specifically in the probability of mood disorders, substance use disorders, abandonment/neglect, and displaying traits of personality disorders. While most of the adolescents who attempted suicide showed a low probability of these parameters (71.7%), about a third of the sample (28.3%) showed a much more severe clinical profile. Analyses of pertinent contextual and risk factors indicated that those with a more severe clinical profile tend to come from overall more dysfunctional family systems, have more problems in school, and have made a previous attempt. CONCLUSION: We conclude that the adolescent suicide attempt population is a heterogeneous group in need of focused differentiated care specifically targeted to particular subgroups. PMID- 29473476 TI - Challenges of Combining Perspectives. AB - BACKGROUND: Asylum seekers have increased risk of suicide and suicidal behavior, with differences related to origin, gender, and age. There are barriers to communication in clinical encounters between asylum seekers and clinicians. There is insufficient knowledge about how communication in the clinical encounter affects the suicide risk in female asylum seekers. AIMS: To explore the documented communication between female asylum-seeking suicide attempters and clinicians and how it affects treatment. METHOD: The medical records of 18 asylum seeking women who had attempted suicide were analyzed with content analysis. RESULTS: Communication between patients and clinicians was affected by: the unbearable realities of the women; difficulties for clinicians in decoding languages of distress, and understanding trauma and subjective meanings of suicide; challenges of combining patients' and clinicians' perspectives; and a sense of shared powerlessness. LIMITATIONS: The medical records did not give direct access to the patient's experience, only to the patient as documented by the clinician. CONCLUSION: The results suggest that clinicians working with asylum seekers who have attempted suicide need to develop an understanding of social and cultural factors and of trauma issues. A question for further study is how an enhanced integration of context and subjectivity in psychiatric practice would equip clinicians for the specific challenges encountered.

PMID- 29473478 TI - Helicobacter pylori SabA binding gangliosides of human stomach. AB - Adhesion of Helicobacter pylori to the gastric mucosa is a prerequisite for the pathogenesis of H. pylori related diseases. In this study, we investigated the ganglioside composition of human stomach as the target for attachment mediated by H. pylori SabA (sialic acid binding adhesin). Acid glycosphingolipids were isolated from human stomach and separated into subfractions, which were characterized by mass spectrometry and by binding of antibodies, bacteria, and Solanum tuberosum lectin. H. pylori SabA binding gangliosides were characterized as Neu5Acalpha3-neolactohexaosylceramide and Neu5Acalpha3 neolactooctaosylceramide, while the other acid human stomach glycosphingolipids characterized (sulfatide and the gangliosides GM3, GD3, GM1, Neu5Acalpha3 neolactotetraosylceramide, GD1a and GD1b) were not recognized by the bacteria. Defining H. pylori binding glycosphingolipids of the human gastric mucosa will be useful to specifically target this microbe-host interaction for therapeutic intervention. PMID- 29473480 TI - Dual-task training effects on motor and cognitive functional abilities in individuals with stroke: a systematic review. AB - OBJECTIVE: This systematic review aimed to examine the effects of dual-task balance and mobility training in people with stroke. METHODS: An extensive electronic databases literature search was conducted using MEDLINE, PubMed, EBSCO, The Cochrane Library, Web of Science, SCOPUS, and Wiley Online Library. Randomized controlled studies that assessed the effects of dual-task training in stroke patients were included for the review (last search in December 2017). The methodological quality was evaluated using the Cochrane Collaboration recommendation, and level of evidence was determined according to the criteria described by the Oxford Center for Evidence-Based Medicine. RESULTS: About 13 articles involving 457 participants were included in this systematic review. All had substantial risk of bias and thus provided level IIb evidence only. Dual-task mobility training was found to induce more improvement in single-task walking function (standardized effect size = 0.14-2.24), when compared with single-task mobility training. Its effect on dual-task walking function was not consistent. Cognitive-motor balance training was effective in improving single-task balance function (standardized effect size = 0.27-1.82), but its effect on dual-task balance ability was not studied. The beneficial effect of dual-task training on cognitive function was provided by one study only and thus inconclusive. CONCLUSION: There is some evidence that dual-task training can improve single task walking and balance function in individuals with stroke. However, any firm recommendation cannot be made due to the weak methodology of the studies reviewed. PMID- 29473481 TI - Early self-managed focal sensorimotor rehabilitative training enhances functional mobility and sensorimotor function in patients following total knee replacement: a controlled clinical trial. AB - OBJECTIVE: To assess the effects of early self-managed focal sensorimotor training compared to functional exercise training after total knee replacement on functional mobility and sensorimotor function. DESIGN: A single-blind controlled clinical trial. SETTING: University Hospital of Rion, Greece. SUBJECTS: A total of 52 participants following total knee replacement. OUTCOME MEASURES: The primary outcome was the Timed Up and Go Test and the secondary outcomes were balance, joint position error, the Knee Outcome Survey Activities of Daily Living Scale, and pain. Patients were assessed on three separate occasions (presurgery, 8 weeks post surgery, and 14 weeks post surgery). INTERVENTION: Participants were randomized to either focal sensorimotor exercise training (experimental group) or functional exercise training (control group). Both groups received a 12-week home based programme prescribed for 3-5 sessions/week (35-45 minutes). RESULTS: Consistently greater improvements ( F2,98 = 4.3 to 24.8; P < 0.05) in group mean scores favour the experimental group compared to the control group: Timed Up and Go (7.8 +/- 2.9 seconds vs. 4.6 +/- 2.6 seconds); balance (2.1 +/- 0.9 degrees vs. 0.7 +/- 1.2 degrees ); joint position error (13.8 +/- 7.3 degrees vs. 6.2 +/ 9.1 degrees ); Knee Outcome Survey Activities of Daily Living Scale (44.2 +/- 11.3 vs. 26.1 +/- 11.4); and pain (5.9 +/- 1.3 cm vs. 4.6 +/- 1.1 cm). Patterns of improvement for the experimental group over time were represented by a relative effect size range of 1.3-6.5. CONCLUSIONS: Overall, the magnitude of improvements in functional mobility and sensorimotor function endorses using focal sensorimotor training as an effective mode of rehabilitation following knee replacement. PMID- 29473482 TI - Prospective surveillance and targeted physiotherapy for arm morbidity after breast cancer surgery: a pilot randomized controlled trial. AB - OBJECTIVE: To evaluate prospective surveillance and targeted physiotherapy (PSTP) compared to education (EDU) on the prevalence of arm morbidity and describe the associated program cost. DESIGN: Pilot randomized single-blinded controlled trial. SETTING: Urban with assessments and treatment delivered in hospitals. PARTICIPANTS: Women scheduled for breast cancer surgery. INTERVENTIONS: Participants were randomly assigned (1:1) to PSTP ( n = 21) or EDU ( n = 20) and assessed presurgery and 12 months postsurgery. All participants received usual care, namely, preoperative education and provision of an education booklet with postsurgical exercises. The PSTP group was monitored for arm morbidity every three months and referred for physiotherapy if arm morbidity was identified. The EDU group received three education sessions on nutrition, stress and fatigue management. MAIN OUTCOME MEASURES: Arm morbidity was based on changes in the surgical arm(s) from presurgery in four domains: (1) shoulder range of motion, (2) strength, (3) volume, and (4) upper body function. Complex arm morbidity indicated >=2 domains impaired. Second, the cost of the PSTP program was described. RESULTS: At 12 months, 18 (49%) participants (10 PSTP and 8 EDU) had arm morbidity, with EDU participants presenting more complex arm morbidity compared to PSTP participants. PSTP participants attended 4.4 of 5 assessments with 90% retention. The PSTP program cost was $150 covered by the Health Care Provider and the Patient Out-of-Pocket Travel cost was CAN$40. CONCLUSION: Our results suggest that PSTP is feasible among women with breast cancer for early identification of arm morbidity. A larger study is needed to determine the cost and effectiveness benefits. PMID- 29473483 TI - Patient Perceptions of Text Messaging to Improve Antiretroviral Therapy Adherence: A Qualitative Study of Patients in a Ryan White Clinic. AB - Evidence on the use of short message service (SMS) to improve medication adherence in people living with HIV (PLHIV) is mounting, yet qualitative research on patient perceptions regarding SMS content and utility for HIV/AIDS remains nascent. To explore the experience of receiving medication reminders via SMS among PLHIV, 45 uninsured and underinsured PLHIV nested within the intervention arm of a larger study received daily, 1-way SMS adherence reminders. Qualitative data were collected by face-to-face, structured interview and were analyzed using conventional content analysis methods. Three main themes emerged from the data: (1) reminders helping with adherence, (2) concerns about delivery modes, and (3) the need for confidentiality. Study findings offer enhanced focus on an emerging strategy in patient-centered HIV care: Equipped with greater context on the experiences of PLHIV using SMS adherence reminders, health-care providers can offer more targeted support and thereby maximize the benefits of this popular and powerful technology. PMID- 29473484 TI - HIV-Positive Patients' Perceptions of Antiretroviral Therapy Adherence in Relation to Subjective Time: Imprinting, Domino Effects, and Future Shadowing. AB - Antiretroviral treatment adherence barriers are major concerns in HIV care. They are multiple and change over time. Considering temporality in patients' perceptions of adherence barriers could improve adherence management. We explored how temporality manifests itself in patients' perceptions of adherence barriers. We conducted 2 semi-structured focus groups on adherence barriers with 12 adults with HIV which were analyzed with grounded theory. A third focus group served to validate the results obtained. Three temporal categories were manifest in HIV positive patients' perceptions of barriers: (1) imprinting (events with lasting impacts on patients), (2) domino effects (chain of life events), and (3) future shadowing (apprehension about long-term adherence). An overarching theme, weathering (gradual erosion of abilities to adhere), traversed these categories. These temporalities explain how similar barriers may be perceived differently by patients. They could be useful to providers for adapting their interventions and improving understanding of patients' subjective experience of adherence. PMID- 29473485 TI - High Virologic Failure Rates with Maraviroc-Based Salvage Regimens Among Indian Patients: A Preliminary Analysis-Maraviroc Effectiveness in HIV-1 Subtype C. AB - BACKGROUND: There is no information on the clinical effectiveness of Maraviroc (MVC) amongst People Living with HIV (PLHIV) in India infected with HIV-1 Subtype C viruses. METHODS: We conducted a retrospective chart review of adult PLHIV on MVC based Antiretroviral (ARV) regimens for at least 6 months. Maraviroc was initiated amongst PLHIV with documented R5 tropic viruses (determined by in-house population sequencing of the V3 loop in triplicate and interpreted using the Geno2Pheno algorithm) in combination with an Optimized Background regimen (designed using genotypic resistance testing and past ARV history). Plasma viral loads (PVL) are performed 6 months post-initiation and annually thereafter. Primary outcome d. Median duration on MVC treatment was 1.8 years (range 1-2.9 years) while median duration of ART prior to switching to MVC was 13 years. Maraviroc was combined with Darunavir/ritonavir (DRV/r) (n=10), Atazanavir/r (ATV/r) (n=2) and Lopinavir/r (LPV/r) (n=1). All PLHIV were infected with HIV-1 Subtype C. Only 23.3% PLHIV achieved virologic suppression at 6 months and sustained it for 2.3 years. Median CD4 count change from baseline was +117 (n=13), +228 (n=10), +253 (n=9), and +331 (n=4) at 6, 12, 18 and 24 months respectively.

CONCLUSIONS: High rates of virologic failure was seen when MVC was used amongst treatment experienced PLHIV infected with HIV-1 Subtype C in India. was the proportion of PLHIV with virologic success (PVL<50 copies/ml) at last follow up visit. RESULTS: Data on 13 PLHIV were analyze. PMID- 29473486 TI - Striving for the best: WONCA global standards for continuing professional development for family doctors. AB - While all physicians must continue to learn new knowledge through their careers, their post-training continuing professional development (CPD) has received less attention. Problems include lack of support for physicians, frequent deviations from best practices such as mandatory participation, focus on community need, and clear conflicts of interest amongst providers. Additionally, specialists from other disciplines catering to different patient populations often provide CPD for family doctors. The Working Party on Education of the World Organisation of Family Doctors (WONCA) sought to develop global standards in CPD for family doctors. The standards were developed through an iterative process with reference to published best practices for effective CPD. Adapted for family doctors from the World Federation for Medical Education's CPD for Medical Doctors: WFME Global Standards for Quality Improvement', the WONCA CPD Standards for Family Doctors were approved by WONCA Council in November 2016. The objectives of the standards are to: (1) Provide a resource for family doctors and/or groups of family doctors to design and structure a program of CPD to reinforce lifelong learning; (2) Optimise current CPD systems such that, through more effective program design and delivery, family doctors are advancing in patient care and their discipline; (3) Offer a set of globally recognised standards developed through a family medicine perspective to provide feedback on existing CPD programs and systems and encourage international recognition of CPD activities. The WONCA Global CPD Standards should inspire best practices in family medicine CPD, assisting family doctors in providing excellent care.

AB - Background Viral load measurement is commonly applicable to monitor HIV infection in patients to determine the number of HIV-RNA in serum samples of individuals. The aim of the present study was to set up a highly specific, sensitive, and reproducible home-brewed Real-time PCR assay based on TaqMan chemistry to quantify HIV-1 RNA genome. Methods In this study, three sets of primer pairs and a TaqMan probe were designed for HIV subtypes conserved sequences. An internal control was included in this assay to evaluate the presence of inhibition. Standard curve and threshold cycle values were determined using in vitro transcribed RNA from int region of HIV-1. A serial dilution of RNA standards was generated by in vitro transcription, from 10 to 109 copies/ml to find the sensitivity and the limit of detection (LOD) of the assay and to evaluate its performance in a quantitative RT-PCR assay. Results The assay has a low LOD equivalent to 33.13 copies/ml of HIV-1 RNA and a linear range of detection from 10 to 109 copies/ml. The coefficient of variation (CV) for Inter and Intra-assay precision of this in-house HIV Real-time RT-PCR ranged from 0.28 to 2.49% and 0.72 to 4.47%, respectively. The analytical and clinical specificity was 100%. Conclusions The results indicate that the developed method has a suitable specificity and sensitivity and is highly reproducible and cost-benefit. Therefore, it will be useful to monitor HIV infection in plasma samples of individuals. PMID- 29473489 TI - Corrigendum. PMID- 29473488 TI - Breast cancer services in Vietnam: a scoping review. AB - BACKGROUND: Breast cancer incidence has been increasing consistently in Vietnam. Thus far, there have been no analytical reviews of research produced within this area. OBJECTIVES: We sought to analyse the nature andextent of empirical studies about breast cancer in Vietnam, identifying areas for future research and systemsstrengthening. METHODS: We undertook a scoping study using a five-stage framework to review published and grey literature in English and Vietnamese on breast cancer detection, diagnosis and treatment. We focused specifically on research discussing the health system and service provision. RESULTS: Our results show that breast cancer screening is limited, with no permanent or integrated national screening activities. There is a lack of information on screening processes and on the integration of screening services with other areas of the health system. Treatment is largely centralised, and across all services there is a lack of evaluation and data collection that would be informative for recommendations seeking to improve accessibility and quality of breast cancer services. CONCLUSIONS: This paper is the first scoping review of breast cancer services in Vietnam. It outlines areas for future focus for policy makers and researchers with the objective of strengthening service provision to women with breast cancer across the country while also providing a methodological example for how to conduct a collaborative scoping review. PMID- 29473490 TI - Identification and Analysis of Key Residues Involved in Folding and Binding of Protein-carbohydrate Complexes. AB - BACKGROUND: Protein-carbohydrate interactions play vital roles in several biological processes in living organisms. The comparative analysis of binding site residues along with stabilizing residues in protein-carbohydrate complexes provides ample insights to understand the structure, function and recognition mechanism. OBJECTIVE: The main objective of this study is to identify and analyze the residues, which are involved in both folding and binding of the protein carbohydrate complexes. METHODS: We have identified the stabilizing residues using the knowledge of hydrophobicity, longrange interactions and conservation, as well as binding site residues using a distance cutoff of 3.5A between any heavy atoms in protein and ligand. Residues, which are common in stabilizing and binding, are termed as key residues. These key resides are analyzed with various sequence and structure based parameters such as frequency of occurrence, surrounding hydrophobicity, longrange order and conservation score. RESULTS: In this work, we have identified 2.45% binding site residues in a non-redundant dataset of 1130 complexes using distance-based criteria and 7.07% stabilizing residues using the concepts of hydrophobicity, long-range interactions and conservation of residues. Further, 5.9% of binding and 2.04% of stabilizing residues are common to each other, which are termed as key residues. The key residues have been analysed based on protein classes, carbohydrate types, gene ontology functional classifications, amino acid preference and structure-based parameters. We found that all-beta, alpha+beta and alpha/beta have more key residues than other protein classes and most of the KRs are present in beta strands, which shows their importance in stability and binding of complexes. On the ligand side, Lsaccharide has the highest number of key residues and it has a high percentage of KRs in SRs and BRs than other carbohydrate types. Further, polar and charged residues have a high tendency to serve as key residues. Classifications based on gene ontology terms revealed that Lys is preferred in all the three groups: molecular functions, biological processes and cellular components. Key residues have 6 to 9 contacts within the protein and make only one contact with the carbohydrate ligand. These contacts are dominant to form polar-nonpolar contacts followed by the contacts between charged atoms. Further, the influence of sequence and structural parameters such as surrounding hydrophobicity, solvent accessibility, secondary structure, long-range order and conservation score has been discussed. CONCLUSION: The results obtained in the present work provide deep insights for understanding the interplay between stability and binding in protein-carbohydrate complexes. PMID- 29473491 TI - Effect of Laser Therapy on Defensins' Gene Expression in TR146 Epithelial Cell Line. AB - INTRODUCTION: Laser Therapy (LT) has been employed for the treatment of Oral Mucositis (OM) due to its anti-inflammatory, analgesic and bio-stimulatory effects. OBJECTIVE: This pilot study investigated the effect of LT on the expression of DEFB1, DEFB4, DEFB103 genes encoding for the human beta-defensins 1, 2 and 3. MATERIALS AND METHOD: TR146 epithelial cell line, used to mimic oral mucosa, was irradiated with different LT protocols. beta-defensins gene expression was evaluated using TaqMan probes on Real- Time PCR platform. RESULTS AND CONCLUSION: In this cellular model LT decreased mRNA defensins' expression 30 minutes after irradiation but not 24 hours later, suggesting that LT is able to influence beta -defensins production immediately after treatment, while its efficacy decreases over time. PMID- 29473492 TI - Metal ion complexes with pyrazoles, aziridines and diaziridines - synthesis and biological activity. AB - Heterocyclic compounds containing nitrogen ions, like pyrazoles, aziridines, diaziridines and their metal ion complexes with Cu(II), Zn(II) and Ru(III) and others exhibit a wide range of biological activity, including mainly anti inflammatory, antioxidant, anti-cancer, and antimicrobial properties. Biological significance of these molecules and thus their potential use in medicine has driven growing interest into their coordination chemistry. A knowledge of the relationship between the structure of chemical compounds and their activity is needed for the synthesis of the preparations possessing the most beneficial features. The choice of interposed substituents may improve biocidal and antitumor action, reduce the toxicity of the initial substance, or even completely eliminate its adverse effects for healthy tissues. The main aim of this review paper is to present the current state of knowledge concerning the synthesis and biological activity of complexes with small heterocyclic ligands containing transition metal ions. PMID- 29473493 TI - Current limitations in the treatment Parkinson's and Alzheimer's diseases: state of-the-art and future perspective of polymeric carriers. AB - Alzheimer's and Parkinson's disease are the most common neurodegenerative diseases worldwide and their incidence is increasing due to the aging population. At the moment, the available therapies are not disease modifying and have several limitations, some of which are discussed in this review. One of the main limitations of these treatments is the low concentration that drugs reach in the central nervous system after systemic administration. Indeed, the presence of biological barriers, particularly the blood brain barrier (BBB), hinders the effective drug delivery to the brain, reducing the potential benefit coming from the administration of the medication. In this review the mechanisms of transport across the BBB and new methods to improve drug passage across the BBB are discussed. These methods include non-invasive solutions such as intranasal and intravitreal administration, the use of nanotechnology solutions based on polymeric carriers when drug is intravenously injected, orally taken for intestine adsorption or delivered through the dermal mucosa. Also, it provides an analysis of more invasive solutions that include intracranially injected hydrogels and implanted devices for local drug delivery. Efforts in finding new therapeutic drugs blocking neurodegenerative disease progression or reverting their course should be coupled with efforts addressed to efficient drug delivery systems. Hence, new pharmacology discoveries together with advancements in nanotechnologies and biomaterials for regenerative medicine are required to effectively counteract neurodegenerative diseases. PMID- 29473494 TI - Protein Tyrosine Nitration in Lung Cancer: Current Research Status and Future Perspectives. AB - Oxidative/nitrative damage is a crucial element among the complex factors that contribute to lung carcinogenesis. Nitric oxide (NO) free radicals, through chemical modifications such as tyrosine nitration, are significantly involved in lung carcinogenesis and metastasis. NO-mediated protein nitration, which is the addition of the nitro group (-NO2) to position 3 of the phenolic ring of a tyrosine residue, is an important molecular event in lung cancer, and has been studied with mass spectrometry. Nitration is involved in multiple biological processes, including signal transduction, protein degradation, energy metabolism, mitochondrial dysfunction, enzyme inactivation, immunogenic response, apoptosis, and cell death. This article reviews the relationship of NO and its derivates and lung cancer, formation and roles of tyrosine nitration in lung cancer, differences of protein nitration between lung cancer and other inflammatory pulmonary diseases, current status of protein nitration and nitroproteomics in lung cancer, and future perspectives to achieve a better understanding of lung carcinogenesis, for biomarker discovery; and for new diagnostic and prognostic monitoring, and therapeutic targets. PMID- 29473496 TI - Modulation of Hepatic MRP3/ABCC3 by Xenobiotics and Pathophysiological Conditions: Role in Drug Pharmacokinetics. AB - Liver transporters play an important role in the pharmacokinetics and disposition of pharmaceuticals, environmental contaminants, and endogenous compounds. Among them, the family of ATP-Binding Cassette (ABC) transporters is the most important due to its role in the transport of endo- and xenobiotics. The ABCC sub-family is the largest one, consisting of 13 members that include the cystic fibrosis conductance regulator (CFTR/ABCC7); the sulfonylurea receptors (SUR1/ABCC8 and SUR2/ABCC9) and the multidrug resistance-associated proteins (MRPs). The MRP related proteins can collectively confer resistance to natural, synthetic drugs and their conjugated metabolites, including platinum-containing compounds, folate anti-metabolites, nucleoside and nucleotide analogs, among others. MRPs can be also catalogued into "long" (MRP1/ABCC1, -2/C2, -3/C3, -6/C6, and -7/C10) and "short" (MRP4/C4, -5/C5, -8/C11, -9/C12, and -10/C13) categories. While MRP2/ABCC2 is expressed in the canalicular pole of hepatocytes, all others are located in the basolateral membrane. In this review, we summarize information from studies examining the changes in expression and regulation of the basolateral hepatic transporter MPR3/ABCC3 by xenobiotics and during various pathophysiological conditions. We also focus, primarily, on the consequences of such changes in the pharmacokinetic, pharmacodynamic and/or toxicity of different drugs of clinical use transported by MRP3. PMID- 29473495 TI - Virtual Screening in Hepatitis B Virus Drug Discovery: Current Stateof- the-Art and Future Perspectives. AB - Hepatitis B Virus (HBV) is a major global health burden. Interferon alpha and nucleos(t)ide analogues are currently the standard-of-care for chronic HBV infection. However, these antiviral agents have limited efficacy and do not result in a sustained virological response in the majority of infected patients. Virtual Screening (VS) strategies have now a strong impact on drug discovery, the strength of this research field has been corroborated by recent contributions in the development of novel drug candidates which are in clinical trials or which are already available in the clinics. In this context, different VS strategies have been applied to HBV in order to discover novel inhibitors. In this review, we summarize the VS efforts to identify and design novel HBV interventions. We believe that the combination of in silico and in vitro tools can lead to faster validation of novel drug targets which could accelerate the HBV drug discovery and development efforts. PMID- 29473497 TI - Anti-NMDA Receptor Encephalitis: Efficacy of Treatment for Male Patients and miRNA Biomarker. AB - Treatments for the anti-NMDA receptor encephalitis usually include steroids, intravenous immunoglobulin, plasma exchange, plasmapheresis, rituximab, cyclophosphamide and tumor resection. We aimed to compare the efficacy of the treatments including intravenous immunoglobulin, plasma exchange, plasmapheresis, rituximab or cyclophosphamide for male anti-NMDA receptor encephalitis patients without tumor and to discuss potential biomarkers for this disease. The Fisher exact test and the contingency table analysis were used to analyze the treatment efficacy for both male and female these patients. A hierarchical tree method was adopted to analyze the difference of the treatment efficacy between male and female patients. The results revealed that the efficacy rate of plasmapheresis (or plasma exchange) is not inferior to those of intravenous immunoglobulin and rituximab (or cyclophosphamide) for male patients without tumor. In addition, B cell attracting C-X-C motif chemokine 13 (CXCL13) and microRNA let-7b are potential to be treatment response biomarkers for anti-NMDA receptor encephalitis. But they may not be useful prognostic biomarkers for this encephalitis unless they are not biomarkers for other autoimmune encephalitides. PMID- 29473498 TI - Functions and Evolution of Lhcb Isoforms Composing LHCII, the Major Light Harvesting Complex of Photosystem II of Green Eukaryotic Organisms. AB - Oxygenic photosynthesis provides energy and oxygen for almost all forms of life on earth. This process is based on the energy of photons, which is used to split water and use its electrons to reduce carbon atoms to create organic molecules and thus fix the light energy into a chemical form. Two photosytems working in series are involved in light harvesting and conversion. Both are multi-protein supercomplexes composed of a core complex, where the photochemical reaction takes place, and an antenna system involved in light harvesting. In plants and green algae, the antenna of photosystem II, the photosynthetic complex involved in water splitting, comprises the Light Harvesting Complex II (LHCII) trimers, the most abundant membrane protein on earth. LHCII is composed of highly conserved Lhcb isoforms and all green organisms count a high number of Lhcb. In vascular plants they are classified in three distinct subclasses, Lhcb1, 2 and 3, while in algae and non-vascular plants, these isoforms are less differentiated and called Lhcbm proteins. In this review, we compare LHCII proteins of different organisms, from green algae to angiosperms, and discuss the role of the modifications that occurred through evolution. We highlight the various functions of the different isoforms in photosynthesis, ranging from light harvesting, a common role to all these proteins, to regulations of photosynthesis that rely on specific isoforms. PMID- 29473499 TI - Natural Aristolochia Alkaloid Aristololactam-beta-D-glucoside: Interaction with Biomacromolecules and Correlation to the Biological Perspectives. AB - BACKGROUND: Natural aristolochia alkaloids have attracted the attention of both chemists and biologists from the stand point of their structural and pharmacological aspects. Many of the compounds isolated in this group are potent tumor inhibitors. These are divided into nitrophenanthrinic acid, phenanthrene lactams and isoquinoline alkaloids. A number of structure-activity studies have been performed on aristolochia alkaloids. Of particular interest is the molecule with the beta-D-glucoside moiety that has similarity to the clinical anticancer agent daunomycin. OBJECTIVE: The anticancer activity of aristololactam-beta-D glucoside has been thought to be due to its DNA and RNA binding activities among other actions. In this article we focus on the physicochemical property of this alkaloid and the structural and functional aspects of its binding to different nucleic acid and protein structures. METHODS: This review highlights a large number of biophysical studies employing various analytical techniques like absorbance, fluorescence, circular dichroism, thermal melting, viscosity, IR study, isothermal calorimetry and differential scanning calorimetry. RESULT: The detailed binding mechanism in terms of the structural and thermodynamic aspects at the molecular level has been discussed. CONCLUSION: This review enables to assess the high potential of developing aristololactam-beta-Dglucoside and related alkaloids as therapeutic agents. PMID- 29473500 TI - CRISPR-cas System as a Genome Engineering Platform: Applications in Biomedicine and Biotechnology. AB - Genome editing mediated by Clustered Regularly Interspaced Palindromic Repeats (CRISPR) and its associated proteins (Cas) has recently been considered to be used as efficient, rapid and site-specific tool in the modification of endogenous genes in biomedically important cell types and whole organisms. It has become a predictable and precise method of choice for genome engineering by specifying a 20-nt targeting sequence within its guide RNA. Firstly, this review aims to describe the biology of CRISPR system. Next, the applications of CRISPR-Cas9 in various ways, such as efficient generation of a wide variety of biomedically important cellular models as well as those of animals, modifying epigenomes, conducting genome-wide screens, gene therapy, labelling specific genomic loci in living cells, metabolic engineering of yeast and bacteria and endogenous gene expression regulation by an altered version of this system were reviewed. PMID- 29473501 TI - A Novel Finding: Macrophages Involved in Inflammation Participate in Acute Aortic Dissection Complicated with Acute Lung Injury. AB - BACKGROUND: Little is known about the pathogenesis of acute lung injury (ALI) complicated with acute aortic dissection (AAD). OBJECTIVE: We aim to investigate the roles of macrophages-derived matrix metalloproteinase 9 (MMP9) in the development of ALI complicated with AAD and factors involved in the recruitment of macrophages. METHODS: This study included three parts: (i) Determination of serum MMPs, angiotensin II (AngII) and MCP-1 in patients with AAD complicated with ALI or AAD only, non-ruptured chronic aortic aneurysm patients or healthy volunteers using ELISA method. (ii) A novel AAD complicated with ALI model was established by infusing angiotensin II (AngII) to immature rats treated with beta aminopropionitrile monofumarate (BAPN) to identify the potential roles of MMP9 and MCP-1 in AAD complicated with ALI. (iii) Cultured pulmonary microvascular endothelial cell (PMVEC) line was used to investigate how AngII was involved in the release of MCP-1 in rat pulmonary vascular endothelial cells. RESULTS: Serum MMP9, AngII and MCP-1 were remarkably elevated in patients with AAD complicated with ALI. The MMP9 expressed in pulmonary tissues was derived from macrophages. In the animal model, the release of MMP9 from macrophages finally resulted in ALI, while inhibition of MMP9 and MCP-1 contributed to decreased incidence of AAD complicated with ALI. In vitro experiments indicated that AngII triggered overexpression of MCP-1 in PMVECs by activating NF-kappaB signaling pathway. CONCLUSION: AAD complicated with ALI is highly associated with the macrophages infiltrating the pulmonary interstitial tissue and released MMP9 in response to angiotensin II. MCP-1 is closely related to the recruitment of macrophages. PMID- 29473502 TI - Exogenous Hydrogen Sulfide Protects SH-SY5Y Cells from OGD/RInduced Injury. AB - BACKGROUND: Cerebral ischemia reperfusion (CIR) injury is the main pathological mechanism of ischemia stroke, and oxidative stress (OS) plays a vital role during the process of CIR. Recent studies have found that OS can activate MAPK pathway, which mainly functions as a mediator of cellular stresses. It revealed that H2S may exhibit multiple biological functions as a neuroprotector through protecting against OS-induced neuronal injury. But how H2S can attenuate ischemia/reoxygenation injury through MAPK signaling is not clear. The protective mechanism of exogenous hydrogen sulfide (H2S) on oxygen glucose deprivation/reoxygenation (OGD/R) at physiological doses in SH-SY5Y cells were investigated in this study. METHODS: DCFH- DA probe is used to measure intracellular ROS, Real-time PCR and Western blot are used to detect the levels of p38 MAPK, ERK3 and Nrf2. CCK-8 is used to detect cell viability. RESULTS: Comparing with the normal control group, the expressions of ERK3, p38MAPK and Nrf2 mRNA in other three groups were downregulated at the beginning of 24h. After 24h, the expressions of ERK3, p38MAPK and Nrf2 were upregulated significantly compared with the normal control group. When the cells were pretreated with 200MUM NaHS at the beginning of 24h, the expressions of ERK3, p38MAPK and Nrf2 were decreased much more significantly than OGD/R and NaHS groups. CONCLUSION: The present study demonstrated that exogenous H2S exerts a protective effect against OGD/R-induced injury by enhancing the activation of the ERK3, p38MAPK and Nrf2 mRNA. PMID- 29473503 TI - Genetic Variants Identified from GWAS for Predisposition to Type 2 Diabetes Predict Sulfonylurea Drug Response. AB - BACKGROUND: Several SNPs were identified through GWAS for their association with type 2 diabetes which has implications to pancreatic beta-cell physiology. OBJECTIVE: We aimed to study the role of risk alleles of TCF7L2, KCNJ11, CDKN2A, CDKAL1, IGF2BP2, SLC30A8 and KCNQ1 along with pharmacokinetic variants in response to sulfonylureas. METHOD: We performed a prospective study on 209 newly diagnosed subjects; treatment naive T2D subjects were recruited. Individuals were started with glibenclamide monotherapy and followed-up for 12 weeks. Genotyping was done, using PCR-RFLP and TETRA-ARMS PCR and confirmed by DNA sequencing. RESULTS: In univariate regression analysis, KCNJ11 (rs5219) was only the predictor for glibenclamide treatment failure. CONCLUSION: The present data suggests a possible role of KCNJ11 gene in altered response to glibenclamide. PMID- 29473504 TI - Immunotherapy in Non-Small Cell Lung Cancer: Biological Principles and Future Opportunities. AB - Immunotherapy aims to amplify the anticancer immune response through reactivation of the lymphocytic response raised against several tumor neo-antigens. To obtain an effective immune response, this therapeutic approach requires that a number of immunological checkpoints be passed, such as the activation of excitatory costimulatory signals or the avoidance of coinhibitory molecules. Among the immune checkpoints, the interaction of the membrane-bound ligand PD-1 and its receptor PD-L1 has received much attention because of remarkable efficacy in numerous clinical trials for various cancer types, including non-small cell lung cancer (NSCLC). However, several limitations exist with these therapeutic agents when used as monotherapy, with objective responses observed in only 30-40% of patients, with the majority of patients demonstrating innate resistance, and approximately 25% of responders later demonstrating disease progression. Recent developments in the understanding of cancer immunology have the potential to identify mechanisms of innate and acquired resistance to immune checkpoint inhibitors through translational research in human samples. This review focuses on the biological basic principles for immunological checkpoint blockade, and highlights the current status and the perspectives of this therapeutic approach in NSCLC patients. PMID- 29473505 TI - LASP1 in Tumor and Tumor Microenvironment. AB - The growing evidence shows that LIM and SH3 Domain Protein 1 (LASP1) is a multi functional protein that plays important role in forming cytoskeleton and prognostic marker in different cancers. LASP1 expression is correlated with the grade, size, and the metastasis of tumor in clinical samples. And the upregulation of LASP1 facilitates tumor cells proliferation, migration, and invasion perhaps through the interaction with cytoskeleton and increased nuclear translocation. The underlying mechanism of LASP1 on tumor is still in the initial stage; therefore, the signaling pathways in various tumors are specifically summarized to deepen the biological understanding of LASP1. This article systematically summarizes the current status of knowledge regarding the contribution of LASP1 in physiological and pathological processes, especially the progress in tumor. This article also gives an emphasized overview of LASP1 on the correlation with tumor microenvironment. PMID- 29473506 TI - Maturity-Onset Diabetes of the Young: An Overview with Focus on the Middle East. AB - Today, there are more than 32 million patients with diabetes in the Middle East (ME), the number is expected to double by 2040. In contrast to Europe and North America and despite the high prevalence of diabetes in ME, epidemiological data about incident and types of diabetes in the region is very limited. Maturity onset diabetes of the young (MODY) is a subtype of monogenic diabetes representing 2-5% of all diabetes patients. The disease is autosomal dominant mode of inheritance characterized by beta-cell malfunction below the age of 35 years. To date, there are 15 different MODY forms that have been identified; each has a distinct genetic etiology. It is very common that MODY is misdiagnosed between with type 1 or type 2 diabetes. Hence, accurate genetic diagnosis is crucial to individualize the treatment and to improve glycaemia control. New technologies such as next-generation sequencing (NGS) offer an excellent alternative to screen and identify causative MODY mutations. In this review, we summarize the main clinical and genetic characteristics for each MODY form. In addition, we shed light on MODY studies that have been executed in the ME region. PMID- 29473507 TI - Oxidative Stress and Decreased Mitochondrial Superoxide Dismutase 2 and Peroxiredoxins 1 and 4 Based Mechanism of Concurrent Activation of AMPK and mTOR in Alzheimer's Disease. AB - BACKGROUND: Emerging evidence supports the hypothesis that metabolism dysfunction is involved in pathogenesis of Alzheimer's disease (AD). One aspect of metabolic dysfunction includes dysregulation of adenosine monophosphate kinase protein kinase (AMPK) and mammalian target of rapamycin (mTOR) metabolic axis, which is extensively present in some of the leading causes of AD such as cerebrovascular diseases, type 2 diabetes and brain ischaemic events. While the molecular basis underlying this metabolic dysregulation remains a significant challenge, mitochondrial dysfunction due to aging appears to be an essential factor to activate AMPK/mTOR signaling pathway, leading to abnormal neuronal energy metabolism and AD pathology. METHODS: Using immunofluorescent imaging by Lecia confocal microscopy, we analyzed the activation of AMPK/mTOR. Concurrently, the level of mitochondrial antioxidant enzymes of superoxide dismutase 2 (SOD2) and peroxiredoxin 1 and 4 (p1 and p4) along with protein and DANA oxidation were examined to in postmortem brains of AD (n= 8) and normal (n= 7) subjects to evaluate the metabolism dysfunction role in AD pathology. RESULTS: In spite of AMPK inhibitory control on mTOR, concurrent phosphorylation of AMPK and mTOR (p AMPK and p-mTOR) was observed in AD brains with high colocalization with hyperphosphorylated tau. Mitochondrial antioxidant enzymes of SOD2 and p1 and p4 were substantially decreased in p-AMPK, p-mTOR and p-tau positive cells along with higher levels of DNA and protein oxidation. CONCLUSION: Collectively, we conclude that AMPK and mTOR metabolic axis is highly activated in AD brains. While the inhibitory link between AMPK and mTOR seems to be disrupted, we suggest oxidative stress as the underlying mechanism for concurrent activation of AMPK and mTOR in AD. PMID- 29473508 TI - Tolfenamic Acid Prevents Amyloid beta-induced Olfactory Bulb Dysfunction In Vivo. AB - BACKGROUND: Amyloid beta inhibits olfactory bulb function. The mechanisms involved in this effect must include alterations in network excitability, inflammation and the activation of different transduction pathways. Thus, here we tested whether tolfenamic acid, a drug that modulates several of these pathological processes, could prevent amyloid beta-induced olfactory bulb dysfunction. OBJECTIVE: To test whether tolfenamic acid prevents amyloid beta induced alterations in olfactory bulb network function, olfaction and GSK3beta activity. METHOD: The protective effects of tolfenamic acid against amyloid beta induced population activity inhibition were tested in olfactory bulb slices from adult mice, while tolfenamic acid and amyloid beta were bath-applied. We also tested the effects of amyloid-beta in slices obtained from animals pre-treated chronically (21 days) with tolfenamic acid. The effects of amyloid beta micro injected into the olfactory bulbs were also tested, after two weeks, on olfactory bulb population activity and olfaction in control and tolfenamic acid chronically treated animals. Olfaction was assessed with the odor-avoidance and the habituation/cross-habituation tests. GSK3beta activation was evaluated with Western-blot. RESULTS: Acute bath application of tolfenamic acid does not prevent amyloid beta-induced inhibition of olfactory bulb network activity in vitro. In contrast, chronic treatment with tolfenamic acid renders the olfactory bulb resistant to amyloid beta-induced network activity inhibition in vitro and in vivo, which correlates with the inhibition of GSK3beta activation and the protection against amyloid beta-induced olfactory dysfunction. CONCLUSION: Our data further support the use of tolfenamic acid to prevent amyloid beta-induced pathology and the early symptoms of Alzheimer Disease. PMID- 29473509 TI - Bis-coumarin Derivatives and Their Biological Activities. AB - Bis-coumarins have caused great interests in the recent years. These compounds exhibit diverse biological activities which are ascribed to their ability to exert noncovalent interactions with the various active sites in organisms. Some of them such as dicoumarolum and dicoumarol were approved for therapeutic purposes in clinical practice. Encouraged by the above facts, numerous biscoumarin derivatives have been synthesized and screened for their biological activities, and many of them showed promising potency. This review is focused on the biological potential of bis-coumarin derivatives with particular mention of those exhibiting antibacterial, anticoagulant, antiinflammatory, antiviral, anti parasite and antitumor activities, and their structure-activity relationships are also discussed. PMID- 29473510 TI - Synthesis and Antifungal Activity of Coumarins Derivatives Against Sporothrix spp. AB - Sporotrichosis is a serious public health problem in Brazil that affects human patients and domestic animals, mainly cats. Thus, the search for new antifungal agents is required also due to the emergence and to the lack of effective drugs available in the therapeutic arsenal. The aim of this study was to evaluate the in vitro antifungal profile of two synthetic series of coumarin derivatives against Sporothrix schenckii and Sporothrix brasiliensis. The three-components synthetic routes used for the preparation of coumarin derivatives have proved to be quite efficient and compounds 16 and 17 have been prepared in good yields. The inhibitory activity of nineteen synthetic coumarins derivatives 16a-i and 17a-j were evaluated against Sporothrix spp. yeasts and the most potent compounds were 16b and 17i. However, according to concentrations able to inhibit (minimum inhibitory concentrations) and kill (minimum fungicidal concentrations) the cells, 17i was more effective than 16b against Sporothrix spp. Thus, 17i exhibited good antifungal activity against S. brasiliensis and S. schenckii, suggesting that it is an important scaffold for the development of novel antifungal agents. PMID- 29473511 TI - A UBI 31-38 Peptide-coumarin Conjugate: Photophysical Features, Imaging Tracking and Synergism with Amphotericin B Against Cryptococcus. AB - Cryptococcosis is a fungal disease of global significance for which new effective treatments are needed. The conjugation of the synthetic antimicrobial peptide fragment UBI 31-38 to a coumarin derivative showed to be an effective approach for the design of a novel anticryptococcal agent. In addition to antifungal activity, the conjugate exhibited intense fluorescence, which could be valuable for mechanistic investigations of this molecule. In this work, we studied the photophysical properties of the conjugate and confocal scanning laser microscopy was used to inspect the distribution of the peptide-coumarin conjugate in Cryptococcus cell. The synergism of this compound with amphotericin B or fluconazole against C. gattii and C. neoformans strains was also investigated. The results indicated that the fluorescent conjugate alone as well as its combination with amphotericin B are promising tools against cryptococcosis. PMID- 29473512 TI - The Role of Inflammatory Response in Stroke Associated Programmed Cell Death. AB - Stroke represents devastating pathology which is associated with a high morbidity and mortality. Initial damage caused directly by the onset of stroke, primary injury, may be eclipsed by secondary injury which may have a much more devastating effect on the brain. Primary injury is predominantly associated with necrotic cell death due to fatal insufficiency of oxygen and glucose. Secondary injury may on the contrary, lead apoptotic cell death due to structural damage which is not compatible with cellular functions or which may even represent the danger of malign transformation. The immune system is responsible for surveillance, defense and healing processes and the immune system plays a major role in triggering programmed cell death. Severe pathologies, such as stroke, are often associated with deregulation of the immune system, resulting in aggravation of secondary brain injury. The goal of this article is to overview the current knowledge about the role of immune system in the pathophysiology of stroke with respect to programmed neuronal cell death as well as to discuss current therapeutic strategies targeting inflammation after stroke. PMID- 29473513 TI - The Role of LRRK2 in Neurodegeneration of Parkinson Disease. AB - The leucine-rich repeat kinase 2 (LRRK2) gene and alpha-synuclein gene (SNCA) are the key influencing factors of Parkinson's disease (PD). It is reported that dysfunction of LRRK2 may influence the accumulation of alpha-synuclein and its pathology to alter cellular functions and signaling pathways by the kinase activation of LRRK2. The accumulation of alpha-synuclein is one of the main stimulants of microglial activation. Microglia are macrophages that reside in the brain, and activation of microglia is believed to contribute to neuroinflammation and neuronal death in PD. Therefore, clarifying the complex relationship among LRRK2, alpha-synuclein and microglials could offer targeted clinical therapies for PD. Here, we provide an updated review focused on the discussion of the evidence supporting some of the key mechanisms that are important for LRRK2 dependent neurodegeneration in PD. PMID- 29473514 TI - The Role of VE-cadherin in Blood-brain Barrier Integrity Under Central Nervous System Pathological Conditions. AB - The blood-brain barrier (BBB) is a layer between the blood circulation and neural tissue. It plays a pivotal role in maintaining the vulnerable extracellular microenvironment in the neuronal parenchyma. Neuroinflammatory events can result in BBB dysregulation by disturbing adherens junctions (AJs) and tight junctions (TJs). VE-cadherin, as one of the most important components of the vascular system, is specifically responsible for the assembly of AJs and BBB architecture. Here, we present a review, which highlights recently available insights into the relationship between the neuroinflammation and BBB dysregulation. We then explore the specific interaction between VE-cadherin and BBB. Finally, we discuss the changes of VE-cadherin with different neurological diseases from both experimental and clinical studies. An understanding of VE-cadherin in BBB regulation may indicate that VE-cadherin can partially be a biomarker of neuroinflammation disease and lead to novel approaches for abating BBB dysregulation under pathological conditions and the opening of the BBB following central nervous system (CNS) drug delivery. PMID- 29473516 TI - The Essential Role of Primary Caregiver in Early Detection of Familial Hypercholesterolemia and Cardiovascular Prevention. AB - Familial hypercholesterolemia (FH) is a worldwide common autosomal inherited condition associated with premature cardiovascular diseases, both in men and in women (World frequency has been recently estimated to be as high as 1:250). Identifying FH cases early in life could represent a cornerstone to prevent fatal events in adult's life. Pediatricians are well positioned to evaluate the familial cardiovascular risk factors among their young patients, to make a diagnosis and to perform familial screening. The goal of this paper is therefore to emphasize the recognition of this genetic condition at a younger age and to initiate both familial screening and a safe treatment. Prevention of cardiovascular disease starts at an early age in all children, but it may save lives in FH patients. PMID- 29473515 TI - Updates on Genome-Wide Association Findings in Eating Disorders and Future Application to Precision Medicine. AB - Heterogeneity, frequent diagnostic fluctuation across presentations, and global concerns with the absence of effective treatments all encourage science that moves the field toward individualized or precision medicine in eating disorders. We review recent advances in psychiatric genetics focusing on genome-wide association studies (GWAS) in eating disorders. Given that the only eating disorder to be the subject of GWAS to date is anorexia nervosa, we review anorexia GWAS and enumerate the prospects and challenges of a genomics-driven approach towards personalized intervention in eating disorders. PMID- 29473517 TI - The Prevalence of Dyslipidemia and Other Cardiovascular Risk Factors in Youth with Diabetes. AB - BACKGROUND: Individuals diagnosed with diabetes mellitus have an increased risk of cardiovascular disease, often leading to premature morbidity and mortality. As the number of youth developing T1D and T2D continues to grow, early onset predisposes patients to a longer burden of disease and earlier onset of cardiovascular complications. Early identification and effective management and treatment of risk factors can lead to decreased cardiovascular events and improved quality of life. OBJECTIVE: In this study, we describe the prevalence of CVD risk factors in children with diabetes. RESULTS: 274 subjects were included in this study, all > 1 year since the time of diagnosis. 134 participants were male (49%). Mean age was 13.7 years (males); 12.8 years (females). subjects averaged 4 diabetes-related visits per year. At the time of their most recent clinic visit, 33% of subjects had a HbA1c < 8%, and 29% had a HbA1c > 10%. Greater than 50% of subjects were overweight or obese. A significant number of subjects were found to have dyslipidemia, and elevated blood pressure was common. DISCUSSION: CVD risk factors are common in children with diabetes mellitus. Good glycemic control, early identification, and effective life-long management of all CVD risk factors may help decrease the high rate of premature morbidity and mortality in diabetes. PMID- 29473519 TI - Identification of New Chromenone Derivatives as Cholinesterase Inhibitors and Molecular Docking Studies. AB - BACKGROUND: Alzheimer's Disease (AD) is the leading cause of dementia among the aging population. This devastating disorder is generally associated with the gradual memory loss, specified by a decrease of acetylcholine level in the cortex hippocampus of the brain due to hyperactivation of cholinesterases (acetylcholinesterase (AChE) and butyrylcholinesterase (BChE)). OBJECTIVE: Therefore, inactivation of AChE and BChE by inhibitors can increase the acetylcholine level and hence may be an encouraging strategy for the treatment of AD and related neurological problems. METHOD: In this contribution, two series of chromenone-based derivatives were tested by Ellmann's calorimetric method for AChE and BChE inhibition. RESULTS: All the compounds showed inhibitory activity against cholinesterases and some of them exhibited dual inhibition of AChE as well as BChE. The most potent inhibitor of AChE was 2l having an IC50 value of 0.08 +/- 0.03 uM, while 3q inhibited the BChE with an IC50 value of 0.04 +/- 0.01 uM. In case of dual inhibition, 3h showed an inhibitory concentration of 0.15 +/- 0.01 uM for AChE, and 0.09 +/- 0.01 uM for BChE. Molecular docking studies were performed to explore the probable binding modes of the most potent dual inhibitors. CONCLUSION: It can be hypothesized that the inhibitors are able to target cholinesterase pathways and may emerge as a suitable outset for the further development process. PMID- 29473518 TI - Management of Measurable Variable Cardiovascular Disease' Risk Factors. AB - AIM: To summarize the main findings on variable cardiovascular risk factors and their management in everyday practice. METHODS: A narrative review of the relevant literature known to the authors and incorporation of healthy changes tips in defined variable cardiovascular risk factors. RESULTS: There are known variable cardiovascular risk factors to be claimed as those that should be changed in order to achieve a better prevention of cardiovascular disease development. But, most papers are informative and they didn't incorporate exact measures for each variable risk factor. Our paper shows exact measures for each variable cardiovascular risk factor that should be incorporate in everyday practice of family practitioners and cardiologists as well. CONCLUSION: The best cardiovascular disease' prevention should include a multidisciplinary team of experts and the entire community with the support of governmental and non governmental organizations that will contribute to improving the lifestyle of individuals and the entire community through their activities and legal provisions. The most important factors in cardiovascular disease management are: recognizing individual risk factors, monitoring them, and assisting in changes in life-style habits that directly affect the defined risk factors of a patient. The simplest and most practicable guidelines for CV prevention in accordance with the national, cultural and socioeconomic aspects of their country of work are needed. PMID- 29473520 TI - Synthesis and Biological Evaluation of 12N-substituted Tricyclic Matrinic Derivatives as a Novel Family of Anti-Influenza Agents. AB - BACKGROUND: Influenza is still a serious threat to human health with significant morbidity and mortality, so it is desirable to develop novel anti-flu drug agents with novel structures. OBJECTIVE: The main purpose of this research was to explore broad-spectrum anti-flu agents and provide antiviral stockpiles in response to potential future influenza pandemics. METHODS: Fifteen novel 12N substituted tricyclic matrinic derivatives were synthesized and evaluated for their anti-influenza activities against H1N1 subtype taking 12N-p cyanobenzenesulfonyl matrinane (1) as the lead. All prepared compounds were characterized by 1H NMR, 13C NMR and ESI-HRMS. The pharmacokinetics (PK) profile of the key compound was also examined in this study. RESULT: The structure activity relationship study indicated that suitable benzyl groups on 12N atom might be beneficial for the activity. Among them, 12N-p-carboxybenzyl matrinic butane (17g) exhibited the most promising activity with an IC50 value of 16.2 uM and a selective index (SI) value of over 33.4. In addition, compound 17g displayed a good in vivo pharmacokinetic profile with an area under the curve (AUC0-infinity) value of 9.89 uM.h. CONCLUSION: We consider tricyclic matrinic butane derivatives to be a new class of anti-influenza agents and this study provided useful information on further optimization. PMID- 29473521 TI - Synthesis of Oleanolic Acid Analogues and Their Cytotoxic Effects on 3T3 Cell Line. AB - BACKGROUND: Oleanolic acid (OA) is a known natural compound with many important biological activities. Thirteen oleanolic acid derivatives linked at C-3 and C-28 were synthesized and their structures were confirmed by 1H- and 13C NMR and mass spectral analyses. Among them, compounds 4, 6, 8-10, 12, 13 were synthesized for the first time. They were evaluated for their cytotoxic activity. They showed proliferative effect at low concentrations while cytotoxic effect was observed at high concentrations in a dose dependent manner. METHODS: We have first synthesized compounds 1 and 2 from the reaction of methyl iodide and OA. Compound 1 was reduced with LiAlH4 to give compound 3, and compound 2 gave compound 9 with MOMBr as a new compound. The compound 10 was then obtained from the reduction of compound 9 with LiAlH4 as a new oleanolic acid derivative. A diol derivative 11 was synthesized from OA and LiAlH4 at the room temperature. Compound 4 was obtained from the reaction of compound 3 with CBr4 as a new analogue of OA, and the reduction of compound 4 afforded compound 5 as a known product. In addition, we synthesized compounds 6-8 from compound 3 using MsCl, MeI and p-nitrobenzoyl chloride, respectively, in good yields. Compounds 6 and 8 are new analogues of OA. The new compounds 12 and 13 were also synthesized starting from OA using with MOMBr and TBDMSiCl as the reagents. The all synthesized compounds were purified by using column chromatography and/or crystallization. RESULTS: In the present study, thirteen OA derivatives linked at C-28 and (or) C-3 were synthesized and evaluated for their cytotoxic activity on 3T3 cell lines which are the standard fibroblast cell lines, derived from Swiss albino mouse embryo tissue. 3T3 cell viability was observed at low concentrations of the tested triterpenoids while they displayed anti-proliferative effect at higher concentrations. CONCLUSION: Oleanolic acid 28-methyl ester (2) showed fairly different behavior from all the other compounds tested and found to be the least cytotoxic compound. However, at 200 uM concentration, it exhibited the same cytotoxicity with compounds 3, 9 and 10 around 58-59%. Among the tested 13 compounds, 7 exhibited the most drastic decline for the viability from 12,5 uM to 25 uM concentration. Compound 6 displayed the most cytotoxic effect, almost in all concentrations, particularly at 6.25 and 25 uM concentrations while the highest cytotoxic effect at 50 uM was observed for compound 11 among all the tested triterpenoids. As a result, all the tested OA derivatives showed proliferative effect at 1,56 uM although no proliferative effect was observed for OA. Moreover, OA exhibited higher cytotoxic effect than its derivatives, particularly at higher concentrations (50, 100, 200 uM) with an exception for compound 11. Because, the latter showed highest proliferative effect at lowest concentration, and highest anti-proliferative effect at highest concentration which surpassed all the OA derivatives. PMID- 29473522 TI - An Evidence-Based Review of Off-Label Uses of Polidocanol. AB - BACKGROUND: Polidocanol is approved for its competence in the treatment of varicose veins and spider veins; however, unfortunately, many of its off-label uses are still underappreciated. OBJECTIVE: Lack of an appropriate comprehensive review for off-label uses of this medication troubles physicians about making evidence-based decisions on prescribing it for its various outstanding off-label uses. This article attempts to provide physicians with the latest information concerning successful and unsuccessful use of polidocanol as an alternative treatment for esophageal and gastric varices, tendinopathy and epicondylitis, vascular malformations, varicocele, hydrocele and spermatocele, aneurysmal bone cysts, itching, management of gastrointestinal bleeding, simple renal cysts, reducing the incidence and severity of radio-induced dermatitis and hemorrhoids. METHOD: The two databases of MEDLINE and Cochrane Library were searched for all human English studies, published in January 2006 to November 2017, which contained the keyword of "polidocanol" or its alternative MeSH terms. RESULTS: Our search identified a total number of 597 articles. Those articles that were only discussing the approved uses of polidocanol were excluded and the remaining 116 articles were reviewed. Eleven major and 30 minor off-label uses were found within included studies. CONCLUSION: Numerous successful administrations of this drug in a variety of clinical conditions lead to promising perspectives toward it. Sclerotherapy with polidocanol as a minimal-invasive method (having similar outcomes like the prevalent surgeries) may reduce the rate of complications. Furthermore, for determining the most appropriate method and dosage, randomized clinical trials are needed, confirming and providing more clear instructions for different conditions. PMID- 29473523 TI - Drug-induced QT Interval Prolongation in the Intensive Care Unit. AB - BACKGROUND: The most common acquired cause of Long QT syndrome (LQTS) is drug induced QT interval prolongation. It is an electrophysiological entity, which is characterized by an extended duration of the ventricular repolarization. Reflected as a prolonged QT interval in a surface ECG, this syndrome increases the risk for polymorphic ventricular tachycardia (Torsade de Pointes) and sudden death. METHOD: Bibliographic databases as MEDLINE and EMBASE, reports and drug alerts from several regulatory agencies (FDA, EMEA, ANMAT) and drug safety guides (ICH S7B, ICH E14) were consulted to prepare this article. The keywords used were: polymorphic ventricular tachycardia, adverse drug events, prolonged QT, arrhythmias, intensive care unit and Torsade de Pointes. Such research involved materials produced up to December 2017. RESULTS: Because of their mechanism of action, antiarrhythmic drugs such as amiodarone, sotalol, quinidine, procainamide, verapamil and diltiazem are associated to the prolongation of the QTc interval. For this reason, they require constant monitoring when administered. Other noncardiovascular drugs that are widely used in the Intensive Care Unit (ICU), such as ondansetron, macrolide and fluoroquinolone antibiotics, typical and atypical antipsychotics agents such as haloperidol, thioridazine, and sertindole are also frequently associated with the prolongation of the QTc interval. As a consequence, critical patients should be closely followed and evaluated. CONCLUSION: ICU patients are particularly prone to experience a QTc interval prolongation mainly for two reasons. In the first place, they are exposed to certain drugs that can prolong the repolarization phase, either by their mechanism of action or through the interaction with other drugs. In the second place, the risk factors for TdP are prevalent clinical conditions among critically ill patients. As a consequence, the attending physician is expected to perform preventive monitoring and ECG checks to control the QTc interval. PMID- 29473524 TI - Pharmacogenetics of Glucagon-like Peptide-1 Agonists for the Treatment of Type 2 Diabetes Mellitus. AB - BACKGROUND: Pharmacogenetics is a promising area of medical research, providing methods to identify the appropriate pharmaceutical agent and dosing for each unique patient. Glucagon- like peptide-1 (GLP-1) agonists are a novel therapeutic choice used in the treatment of type 2 diabetes mellitus (T2DM), demonstrating efficacy regarding glycemic control and weight loss. Therapeutic response to GLP 1 agonist treatment is a complex biophenomenon, dependent on a plethora of modifiable (diet, exercise, adherence) and non-modifiable (genetic individual variants, ethnic characteristics) parameters. Iotan this context, it has been hypothesized that genetic polymorphisms of GLP-1 related genes may be associated with the therapeutic response to GLP-1 agonist treatment. This review focuses on the most important polymorphisms of the GLP-1 biological network that could affect clinical response to GLP-1 agonist treatment. METHODS: Biomedical databases were searched to identify key articles in the field and their results are critically presented in this review. RESULT: Recent pharmacological and clinical studies demonstrated a significant variation in GLP-1 agonist treatment, in cohorts with homogeneous adherence to diet, exercise and antidiabetic treatment. These studies identified several cases of non-responders to GLP-1 agonist therapy, in association with specific allelic patterns of GLP-1 receptor or other biomolecules implicated in glucose homeostasis. CONCLUSION: Although the exact DNA sequences that cause the molecular changes leading to a variable response to GLP-1 agonists have not been yet fully identified, these findings underline the importance of an individualized approach in anti-diabetic treatment. PMID- 29473525 TI - Oral Mucosal Stem Cells, Human Immature Dental Pulp Stem Cells and Hair Follicle Bulge Stem Cells as Adult Stem Cells Able to Correct Limbal Stem Cell Deficiency. AB - BACKGROUND: Adult stem cells are somatic stem cells distributed all over the body. They represent a promising future for regenerative medicine because of their multiple advantages as they are widely available, accessible, easily stored and manipulated to a wide range of cells and with minimal invasive extraction. OBJECTIVE: This review describes three examples of adult stem cells: oral mucosal epithelial stem cells, human immature dental pulp stem cells and hair follicle bulge stem cells that show an ability to correct limbal stem cell deficiency, their isolation and cultivation methods, feeder layers, carriers, markers expressed, successfulness to regenerate the ocular surface and mimic the corneal function in LSCD. CONCLUSION: Although hair follicle bulge stem cells and human immature dental pulp stem cells are a promising adult stem cell source to correct limbal stem cell deficiency, but the published research evaluating this ability is limited. Therefore, this article emphasize further research in this area. PMID- 29473526 TI - There is no difference between sequences of HIV-1 infected patients with stable clinical status and HIV-1 reference sequence. AB - BACKGROUND: The rate of human immunodeficiency virus type 1 (HIV-1) infection in Iran has increased dramatically in the past few years. HIV-1 genome sequences are pivotal for large-scale studies of inter- and intra-host evolution. To understand the molecular difference between reference HIV-1 isolate and two HIV-1 infected patients in Iran, we conducted this study to analyze some genome segments of Iranian HIV-1 isolates. METHODS: Two HIV-1-infected individuals who were under antiretroviral therapy (ARV) for 8 years with stable clinical status were enrolled. Gag-Pol genome sequences (4500 nt) obtained from patient's plasma samples were used for constructing phylogenetic tree and analyzing similarity plotty. RESULTS: Both isolates belonged to CRF35_AD subtype. One of them had drug resistance. Our patient's HIV genome and protein isolates showed no clear difference with genome and protein sequences of reference sequence. CONCLUSIONS: our patient's stable clinical status had no connection to genome sequence; it could be owing to immunological factors or other patient's mode which are still unknown. PMID- 29473527 TI - Glucose Lowering Activity of Anvillea Radiata Coss & Durieu in Diabetic Rats. AB - INTRODUCTION: Anvillea radiata Coss. & Durieu (Asteraceae) is an endemic plant from North Africa (Morocco and Algeria). This plant has many traditional uses including treatment of obesity and diabetes. AIM OF THE STUDY: The study aims to evaluate the antidiabetic effect of aqueous extract of Anvillea radiata (A. radiata) leaves on both normal and streptozotocin (STZ)-induced diabetic rats treated at a dose of 10 mg/kg body weight for fifteen days. In addition, a preliminary pytochemical screening for various components was realized. RESULTS: The blood glucose levels were lowered in diabetic rats treated with A. radiata, but no effect was observed in normal rats. Single oral administration of A. radiata reduced blood glucose levels from 22.15+/-0.98 mmol/L to 14.00+/-1.89 mmol/L (p<0.0001) six hours after administration in STZ diabetic rats. Furthermore, blood glucose levels were decreased from 22.15+/-0.98 mmol/L to 4.39+/-1.29 mmol/L (p< 0.0001) in STZ diabetic rats after fifteen days of treatment. According to the oral glucose tolerance test, the A. radiata (10 mg/kg) was shown to significantly prevent the increase in blood glucose levels in normal treated rats 30 min, 60 min and 120 min after glucose administration when compared to the control group. Concerning the preliminary phytochemical screening of A. radiata, several compounds of chemicals have been found such as polyphenols, flavonoids, tannins, mucilage, sesquiterpenes, terpenoids and carbohydrates. CONCLUSION: The results show that aqueous extract of A. radiata leaves possesses a significant antihyperglycemic activity. PMID- 29473528 TI - Novel Genetic Tool to Study the Stability of Genomic Islands. AB - BACKGROUND: Genomic islands (GIs) are discrete segments of mobile DNA with defined boundaries according to recent patents, acquired in the bacterial genome from another organism by horizontal gene transfer during the course of evolution. GIs contribute significantly to virulence, disease development, antimicrobial resistance and metabolic process. OBJECTIVE: The present study focuses on the development of a vector based genetic tool carrying selectable and counter selectable markers, in order to flag the GIs in the bacterial chromosome and monitor their stability under in vitro and in vivo conditions. METHOD: We engineered suicide vectors, pSB40 and pSB41, carrying single or tandem copies of chloramphenicol acetyltransferase (cat) and levansucrase (sacB) alleles, respectively. The sacB-cat allele in both the vectors is flanked by several restriction sites. To test the suitability of sacB-cat allele for monitoring GI loss, we introduced the allele in the Vibrio Pathogenicity Island-1 (VPI-1) in Vibrio cholerae genome. RESULTS: The V. cholerae strain carrying sacB-cat allele in VPI-1 element showed resistance to chloramphenicol and sensitivity to sucrose at optimal growth conditions. Loss of VPI-1 element from the V. cholerae genome was simply monitored by growing the cells on selection agar plates supplemented with sucrose. Our results showed that the genetic tool we developed is suitable for monitoring GI stability in the bacterial genome. CONCLUSION: The present study indicates that pSB40 and pSB41are efficient and sensitive genetic tool that can be used for reverse genetics experiments and monitoring stability of mobile genetic elements in the bacterial genome. PMID- 29473529 TI - Application of Cocrystallization Approach in Drug Development: Recent Patents Review. AB - BACKGROUND: Cocrystals of active pharmaceutical ingredient has been of interest in the field of pharmaceutical research due to their potential for tailoring the physicochemical properties of pharmaceutical molecules.

PMID- 29473530 TI - Allergoids for Allergy Treatment. AB - BACKGROUND: Chemically modified allergen extracts, known as allergoids, are commonly used for treating allergic patients. In general terms, the concept of allergoids implies allergen extracts with a reduction of their allergenicity maintaining their immunogenicity. Different methods to obtain allergoids have been developed in the past years, opening attractive lines of research. OBJECTIVE: To review the different approaches to allergoid development as well as their characterization, mechanism of action and efficacy and safety issues. METHODS: A revision and analysis of the different types of allergoids has been performed, with special attention to patents submitted and granted in the last years. Additionally, updated information about the mechanism of action and clinical evidence and safety of allergoids has been discussed. RESULTS: Principally, allergoids are obtained by the polymerization of native allergen extracts with aldehydes, including formaldehyde or glutaraldehyde. However, recent patents and publications about different chemical modifications have been presented, as well as about the use of new adjuvants with allergoids. Regarding the characterization, allergoids require more sophisticated analytical methods than native extracts, as a consequence of their properties and characteristics. CONCLUSION: In the last years, the partial understanding of the mechanism of action and the generation of clinical evidence of different types of allergoids, linked to their excellent safety profile and their convenience for a quick build up phase, have made of allergoids an excellent product for allergy treatment.

RESULTS: A number of biological properties, including antimicrobial, anti-inflammatory, antiparasitic, antitumor, antioxidant, metabolic and nutraceutical activities are attributed to RdProp, demonstrating the great potential of its use in the food, pharmaceutical and cosmetics industries. CONCLUSION: The available papers are associated to pharmacological potential of RdProp, but the molecular mechanisms or bioactive compounds responsible for each activity have not yet been fully elucidat ed. The RdProp patents currently found are directed to components for the pharmaceutical industry (EP2070543A1; WO2014186851A1; FR3006589A1; CN1775277A; CN105797149A; CN1879859A), cosmetic (JP6012138B2; JP2008247830A; JP6012138B2) and food (JP5478392B2; CN101380052A; WO2006038690A1). PMID- 29473535 TI - An Overview of Hepatoprotective Effects of Thymoquinone. AB - BACKGROUND: Liver diseases are globally recognized as major medical problems. Several species of herbal medicine have been investigated for the management of liver-related diseases. OBJECTIVE: In this context, Thymoquinone (TQ) as the main constituent of Nigella sativa has long been focused for the treatment of liver diseases in recent years. To suppressing liver diseases, it was reported that TQ exhibits hypolipidic effects, which prevented the fatty acid accumulation in the hepatocytes. The other activity of TQ, not only in the management of chronic liver diseases but also regarding the carcinogenesis, is its potent antioxidant effects, which affect several signaling pathways. RESULT: The effect of TQ on NF kappabeta is the hepatoprotective effect of this flavonoid. Recently, a few patents of TQ derivatives for protective effects have been developed.

AB - BACKGROUND: Ligaria cuneifolia (Lc) (R. et P.) Tiegh. (Loranthaceae) (Argentine mistletoe) is usually used in local folk medicine. OBJECTIVE: We studied the effect of treatment with the Lc proanthocyanidin-enriched fraction (PLc) in rats fed with Cho-enriched diet on plasma lipids levels, the hemorheological parameters, and biliary secretion. METHOD: Adult male Wistar rats were fed ad libitum with a Cho-enriched diet (Cho (97% purity) 8 g/kg of diet and corn oil 280 g/kg of diet) during 28 days. Then, were separated in six experimental groups (n=5 each one), which were injected ip every 24 h with: 1) saline solution (control group, C) and 2) PLc, 3 mg/100 g body weight (treated group, C+PLc), during 3, 7 and 10 days. Group C presented an increase in plasma levels of Cho and Triglycerides (TG), and also, accumulation of hepatic lipid droplets. Also, cell shape and their corresponding morphological index (MI) were altered too. RESULTS: The treatment with PLc at 3, 7 and 10 days produces a diminution in the plasma Cho, LDL-Cho and serum TG levels, accompanied by a diminution of the lipid accumulation in the liver. The rates of bile acid output in bile can explain the diminution of plasma Cho, evidencing that some of the enzymes involved in the cholesterol conversion into bile acids could be up regulated by the treatment with PLc, leading to the observed increase bile flow. PLc treatment leads to a diminution of plasma levels of Cho and TG. CONCLUSION: Essentially, the treatment with PLc, despite the duration produces a modification in hemorheological parameters approaching the values of the experimental group with standard diet. Plasma levels of Cho, LDL-Cho and TG represent selected markers to evaluate the effect of enriched extract from Ligaria cuneifolia. Further work is necessary to better evaluate the mechanisms by which PLc induces modifications in the lipids metabolism. PMID- 29473536 TI - [Dermatomyositis as a paraneoplastic syndrome]. AB - BACKGROUND: Dermatomyositis is an idiopathic inflammatory myopathy with an incidence of 1 in 100,000. Clinically, it features typical skin abnormalities and muscle weakness. In a subset of cases an underlying malignancy may be present; in such instances the term paraneoplastic syndrome is used. CASE DESCRIPTION: We saw a 75-year-old male with progressive skin abnormalities, especially on the chest and hands. In addition, he experienced weakness in his arms and legs. Three months earlier, he was diagnosed with prostate cancer. Following additional investigations, the diagnosis of dermatomyositis was made and treatment with prednisone proved successful. CONCLUSION: In a patient with typical skin abnormalities one should consider dermatomyositis and it is important to investigate for the presence of muscle disorders and occult malignancy. The muscle symptoms often respond well to prednisone, but the skin abnormalities are usually harder to resolve, Treatment of a possible underlying malignancy also influences the dermatomyositis.

AB - There is no such thing as a perfect diagnostic test and the value of a test depends on the situation in which the test is being used. Here, we discuss two options for dealing with the diagnostic process for Lyme borreliosis in general practice. One option is to manage, treat or refer according to clinical signs and symptoms, in accordance with Dutch practice guidelines. The other option is to use laboratory tests to guide further patient management (treatment or referral). The choice depends on currently unknown factors, such as the pre-test probability of Lyme disease in patients presenting to general practitioners. Furthermore, clarity is required about how to proceed after a positive or negative test result. The consequences of a false test result will depend on the patient's status, possible alternative diagnoses and treatment options. Both physician and patient should be aware of the shortcomings of diagnostic tests. PMID- 29473538 TI - [A woman with swelling and blue-red discolouration of the leg]. AB - A 61-year-old woman presented with a sudden marked swelling and blue-red discolouration of her entire left leg. The diagnosis phlegmasia cerulea dolens was made. This is an extreme case of lower-extremity deep venous thrombosis that can cause critical limb ischaemia and possible limb loss. PMID- 29473539 TI - [Myositis: more than a muscle disease]. AB - Idiopathic inflammatory myopathy (IIM), commonly referred to as "myositis", is a rare but treatable auto-immune disease that is often misdiagnosed or diagnosed after significant delay. Using three clinical case reports as introductory examples, an overview is given - and pitfalls are discussed - of the diagnosis and treatment of myositis. Disease features are often extra-muscular in nature, may vary considerably between patients, and are frequently non-specific. Myositis related morbidity is high and myositis can be fatal, mainly due to cancer and interstitial lung disease. As such, we stress the importance of early recognition of this severe disease and timely referral of a patient with a (suspected) IIM to a multidisciplinary team for optimal diagnosis and disease management. PMID- 29473540 TI - [Prevention of postoperative infections: patient safety subordinated to antibiotic stewardship]. AB - A new Dutch guideline for surgical antimicrobial prophylaxis recommends preoperative treatment with mupirocin and chlorhexidine showers only in patients identified as nasal carriers of Staphylococcus aureus. Yet, preoperative screening and treatment may not be achieved in many patients, because of the infrastructural complexity of all procedures this requires. We are therefore pleading for a universal treatment approach, which is more cost-effective and precludes carriers from being missed, while monitoring the occurrence of S. aureus infections caused by mupirocin-resistant strains. PMID- 29473541 TI - A kinase-dependent feedforward loop affects CREBB stability and long term memory formation. AB - In Drosophila, long-term memory (LTM) requires the cAMP-dependent transcription factor CREBB, expressed in the mushroom bodies (MB) and phosphorylated by PKA. To identify other kinases required for memory formation, we integrated Trojan exons encoding T2A-GAL4 into genes encoding putative kinases and selected for genes expressed in MB. These lines were screened for learning/memory deficits using UAS RNAi knockdown based on an olfactory aversive conditioning assay. We identified a novel, conserved kinase, Meng-Po (MP, CG11221, SBK1 in human), the loss of which severely affects 3 hr memory and 24 hr LTM, but not learning. Remarkably, memory is lost upon removal of the MP protein in adult MB but restored upon its reintroduction. Overexpression of MP in MB significantly increases LTM in wild type flies showing that MP is a limiting factor for LTM. We show that PKA phosphorylates MP and that both proteins synergize in a feedforward loop to control CREBB levels and LTM. key words: Drosophila, Mushroom bodies, SBK1, deGradFP, T2A-GAL4, MiMIC. PMID- 29473542 TI - Facile preparation of a TiO2 quantum dot/graphitic carbon nitride heterojunction with highly efficient photocatalytic activity. AB - In this article, mechanical grinding, an effortless and super-effective synthetic strategy, is used to successfully synthesize a TiO2 quantum dot (TiO2QD)/graphitic carbon nitride (g-C3N4) heterostructure. X-ray photoelectron spectroscopy results together with transmission electron microscopy reveal the formation of the TiO2QD/g-C3N4 heterostructure with strong interfacial interaction. Because of the advantages of this characteristic, the prepared heterostructure exhibits excellent properties for photocatalytic wastewater treatment. Notably, the optimum photocatalytic activity of the TiO2QD/g-C3N4 heterostructure is nearly 3.4 times higher than that of the g-C3N4 nanosheets used for the photodegradation of rhodamine B pollutant. In addition, the stability and possible degradation mechanism of the TiO2QD/g-C3N4 heterojunction are studied in detail. This method may stimulate an effective approach to synthesizing QD-sensitized semiconductor materials and facilitate their application in environmental protection. PMID- 29473543 TI - Creating virtual electrodes with 2D current steering. AB - OBJECTIVE: Current steering techniques have shown promise in retinal prostheses as a way to increase the number of distinct percepts elicitable without increasing the number of implanted electrodes. Previously, it has been shown that 'virtual' electrodes can be created between simultaneously stimulated electrode pairs, producing unique cortical response patterns. This study investigated whether virtual electrodes could be created using 2D current steering, and whether these virtual electrodes can produce cortical responses with predictable spatial characteristics. APPROACH: Normally-sighted eyes of seven adult anaesthetised cats were implanted with a 42-channel electrode array in the suprachoroidal space and multi-unit neural activity was recorded from the visual cortex. Stimuli were delivered to individual physical electrodes, or electrodes grouped into triangular, rectangular, and hexagonal arrangements. Varying proportions of charge were applied to each electrode in a group to 'steer' current and create virtual electrodes. The centroids of cortical responses to stimulation of virtual electrodes were compared to those evoked by stimulation of single physical electrodes. MAIN RESULTS: Responses to stimulation of groups of up to six electrodes with equal ratios of charge on each electrode resulted in cortical activation patterns that were similar to those elicited by the central physical electrode (centroids: RM ANOVA on ranks, p > 0.05; neural spread: one way ANOVA on Ranks, p > 0.05). We were also able to steer the centroid of activation towards the direction of any of the electrodes of the group by applying a greater charge to that electrode, but the movement in the centroid was not found to be significant. SIGNIFICANCE: The results suggest that current steering is possible in two dimensions between up to at least six electrodes, indicating it may be possible to increase the number of percepts in patients without increasing the number of physical electrodes. Being able to reproduce spatial characteristics of responses to individual physical electrodes suggests that this technique could also be used to compensate for faulty electrodes.

AB - This paper reviews biokinetic data for the Group VB elements vanadium, niobium, and tantalum, and presents biokinetic models describing their systemic behaviour. The model for systemic niobium in adults was developed earlier and described in Publication 134 of the International Commission on Radiological Protection. The model for niobium is used as a starting point for the development of models for vanadium and tantalum. Published biokinetic data for vanadium, including comparisons with niobium, indicate that the initial distribution of vanadium is broadly similar to that of niobium but that vanadium is less firmly fixed in most tissues and is excreted more rapidly than niobium. Biokinetic data for tantalum are more limited but suggest that its systemic behaviour closely resembles that of niobium at early times after administration. The model for niobium is proposed for application to tantalum in view of the suggested biological similarities of tantalum and niobium, their generally strong coherence in nature due to similar ionic radii and identical valence states, and the difficulties in developing parameter values directly from available data for tantalum. The proposed model for vanadium relies largely on vanadium-specific information and varies considerably from the model for niobium. PMID- 29473546 TI - Excellent microwave response derived from the construction of dielectric-loss 1D nanostructure. AB - Increasing efforts have recently been devoted to the artificial design and function of nanostructures for their application prospects in catalysis, drug delivery, energy storage, and microwave absorption. With the advantages of natural abundance, low cost, and environment friendliness, a one-dimensional (1D) MnO2 nanowire (MW) is the representative dielectric-loss absorber for its special morphology and crystalline structure. However, its low reflection loss (RL) value due to its thin thickness limits its wide development and application in the microwave absorption field. In this work, artificially designed MnO2@AIR@C (MCs), namely, 1D hollow carbon nanotubes filled with nano-MnO2, were designed and synthesized. It is found that the RL value of the MC is almost lower than -10 dB. Furthermore, the RL value was able to achieve -18.9 dB with an effective bandwidth (-10 dB) of 5.84 GHz at 2.25 mm. Simultaneously, the dielectric and interfacial polarization became stronger while the impedance matching was much better than in the single MWs. Hence, the rational design and fabrication of micro-architecture are essential and MC has great potential to be an outstanding microwave absorber. PMID- 29473547 TI - Coupling mechanical tension and GTPase signaling to generate cell and tissue dynamics. AB - Regulators of the actin cytoskeleton such Rho GTPases can modulate forces developed in cells by promoting actomyosin contraction. At the same time, through mechanosensing, tension is known to affect the activity of Rho GTPases. What happens when these effects act in concert? Using a minimal model (1 GTPase coupled to a Kelvin-Voigt element), we show that two-way feedback between signaling ('RhoA') and mechanical tension (stretching) leads to a spectrum of cell behaviors, including contracted or relaxed cells, and cells that oscillate between these extremes. When such 'model cells' are connected to one another in a row or in a 2D sheet ('epithelium'), we observe waves of contraction/relaxation and GTPase activity sweeping through the tissue. The minimal model lends itself to full bifurcation analysis, and suggests a mechanism that explains behavior observed in the context of development and collective cell behavior. PMID- 29473548 TI - Cosmology with the Large Synoptic Survey Telescope: an overview. AB - The Large Synoptic Survey Telescope (LSST) is a high etendue imaging facility that is being constructed atop Cerro Pachon in northern Chile. It is scheduled to begin science operations in 2022. With an [Formula: see text] ([Formula: see text] effective) aperture, a novel three-mirror design achieving a seeing-limited [Formula: see text] field of view, and a 3.2 gigapixel camera, the LSST has the deep-wide-fast imaging capability necessary to carry out an [Formula: see text] survey in six passbands (ugrizy) to a coadded depth of [Formula: see text] over 10 years using [Formula: see text] of its observational time. The remaining [Formula: see text] of the time will be devoted to considerably deeper and faster time-domain observations and smaller surveys. In total, each patch of the sky in the main survey will receive 800 visits allocated across the six passbands with [Formula: see text] exposure visits. The huge volume of high-quality LSST data will provide a wide range of science opportunities and, in particular, open a new era of precision cosmology with unprecedented statistical power and tight control of systematic errors. In this review, we give a brief account of the LSST cosmology program with an emphasis on dark energy investigations. The LSST will address dark energy physics and cosmology in general by exploiting diverse precision probes including large-scale structure, weak lensing, type Ia supernovae, galaxy clusters, and strong lensing. Combined with the cosmic microwave background data, these probes form interlocking tests on the cosmological model and the nature of dark energy in the presence of various systematics. The LSST data products will be made available to the US and Chilean scientific communities and to international partners with no proprietary period. Close collaborations with contemporaneous imaging and spectroscopy surveys observing at a variety of wavelengths, resolutions, depths, and timescales will be a vital part of the LSST science program, which will not only enhance specific studies but, more importantly, also allow a more complete understanding of the Universe through different windows.

PMID- 29473553 TI - Microbial DNA testing for inflammatory diseases of the brain of uncertain etiology. AB - Neurologists may be confronted with patients who present with inflammatory brain lesions where the diagnosis cannot be made through history and physical examination alone. Molecular testing for bacterial infections, tuberculosis, and fungal infections may aid in the diagnosis. Since the treatments for these disorders are different and delays can result in permanent neurologic disability and death, rapid and accurate diagnoses are critical. This review provides the neurologist with testing options and recommends ways to enhance sensitivity and specificity. PMID- 29473554 TI - Multisensory remission of somatoparaphrenic delusion: My hand is back! AB - This study investigates whether the rubber hand illusion (RHI) can induce a remission of somatoparaphrenia, a somatic delusion usually following right hemisphere damage, which typically manifests as a defective sense of ownership of one's contralesional body parts. First, we show that patients with somatoparaphrenia can experience a reliable RHI, exhibiting illusory effects similar to those reported by healthy participants. Moreover, synchronous touches applied to the patients' visible disowned left hand (rather than to the rubber hand), and to their right invisible unimpaired hand, induce an immediate self attribution of the disowned hand, without affecting other sensorimotor or attentional disorders. The higher-level representation of the body concerned with ownership, deranged as a somatic delusion in patients with somatoparaphrenia, is penetrable, and can be restored by multisensory stimulations. PMID- 29473555 TI - The menagerie of neurology: Animal signs and the refinement of clinical acumen. AB - Neurology is a field known for "eponymophilia." While eponym use has been a controversial issue in medicine, animal-related metaphoric descriptions continue to flourish in neurologic practice, particularly with the advent of neuroimaging. To provide practicing and trainee neurologists with a useful reference for all these colorful eponyms, we performed a literature review and summarized the various animal eponyms in the practice of neurology (and their etiologic implications) to date. We believe that the ability to recognize animal-like attributes in clinical neurology and neuroradiology may be attributed to a visual phenomenon known as pareidolia. We propose that animal eponyms are a useful method of recognizing clinical and radiologic patterns that aid in the diagnostic process and therefore are effective aidesmemoire and communicative tools that enliven and improve the practice of neurology.

PMID- 29473559 TI - Diagnostic and therapeutic spinal interventions: Facet joint interventions. AB - Axial spine pain is a common condition that is due to facet joint disease in some patients. Local anesthetic blocks of the medial branches of the dorsal rami of the spinal nerves that innervate facet joints are used to identify painful facet joints. Subsequent radiofrequency neurotomy of the medial branches serving symptomatic facet joints may provide prolonged albeit impermanent pain relief. The diagnostic blocks and radiofrequency treatments are best validated in the cervical spine. Neurologists should be aware that patients with axial spine pain who are referred to a pain clinic or pain management facility are likely to be considered for diagnostic and therapeutic interventions directed at facet joints and their sensory nerve supply. PMID- 29473561 TI - Current controversies: Physicians vs Pharma. PMID- 29473562 TI - Diagnostic and therapeutic spinal interventions: Diskography. AB - Diskography (provocation diskography, disk stimulation) is an invasive diagnostic test performed to confirm or exclude internal disk disruption as the cause of axial spine pain. Diskography involves injecting fluid into the nucleus of the disk under manometric control; a positive response is reproduction of typical pain. Extensive but indirect literature validates diskography in the lumbar spine; it is less well-supported in the cervical or thoracic spine. Risks include rare instances of infection and neural injury; lumbar diskography may be associated with accelerated disk degeneration. Diskography has utility in establishing a diagnosis of diskogenic pain. When negative, it prevents inappropriate interventions directed at the disk; when positive, it prevents interventions directed at other axial pain generators. Its role in selecting patients for therapies directed at diskogenic pain is limited by the lack of available validated treatments. PMID- 29473563 TI - Are randomized, blind clinical trials enough to guide individualized decisions for patients with neurologic diseases? AB - The practice of medicine relies on the patient-physician relationship, knowledge, and clinical judgment. Randomized controlled trials (RCTs) remain the least biased method for studying the effects of interventions in selected populations and are the only method to control adequately for unknown confounders. However, physicians face the limitations of RCTs on a daily basis as they treat relatively unselected populations and individual patients. We explore the benefits and limitations of RCTs for some neurologic disorders, and discuss the difficulties of predicting individualized outcomes and anticipating treatment responses in those heterogeneous conditions. Observational studies and advances in understanding neurologic diseases complement RCTs in decision-making. Considerable challenges remain for personalized medicine; for now, clinicians must rely on their ability to integrate evidence and clinical judgment. PMID- 29473564 TI - Diagnostic and therapeutic spinal interventions: Epidural injections. AB - Epidural injections of local anesthetic or a corticosteroid are frequently given to diagnose and treat patients with radicular pain originating from any spinal level. The best-quality evidence supports a transforaminal approach in the lumbar spine. Many patients experience substantial benefit from a single therapeutic injection. Depending upon the benefit obtained, additional injections may be administered. Selective nerve blocks with local anesthetic alone can identify the spinal nerve mediating the patient's pain. Serious short-term risks are rare but occur; long-term risks are infrequent and can be due to systemic effects of multiple corticosteroid injections. Patients who have failed conservative therapy or are not candidates for surgical intervention can be considered for epidural steroid injections to relieve their radicular pain temporarily. PMID- 29473565 TI - Should I offer vagus nerve stimulation as part of my neurology practice? AB - Vagus nerve stimulation (VNS) is a safe and effective adjunctive therapy approved for patients with partial-onset seizures. A pulse generator, which is implanted in the chest wall, delivers programmed electrical pulses through an electrode that is attached to the left vagus nerve. VNS plays an important role in the treatment of patients with drug-resistant epilepsy. It is currently offered in academic as well as private practice settings. After a comprehensive workup is performed, VNS should be offered to patients with drug-resistant epilepsy who are not candidates for surgery.

In adulthood, white matter hyperintensities are generally related to acquired disorders, such as vascular, inflammatory, or demyelinating diseases. Symmetrical and confluent white matter abnormalities on the first available MRI suggest a genetic disorder. In this article, we provide keys to recognize and classify the adult-onset forms of inherited leukoencephalopathies and to identify their causes by targeting specific biochemical or molecular biomarkers.

AB - Recognizing and treating sleep-disordered breathing (SDB) is essential in delivering neurologic care due to its association with a growing list of neurologic conditions (e.g., stroke, neurodegenerative disorders). Thus, increased proficiency in the recognition and management of SDB is likely to result in better outcomes, care, and utilization of health care resources. To date, continuous positive airway pressure remains the gold standard for patients with moderate to severe obstructive sleep apnea and has been shown to be effective in treating variations of SDB. Appropriate application of new methods and technology such as home sleep testing can help bridge the gap between the need and supply for sleep health care and delivery. Increased focus on efficacious strategies to further awareness and education for patients, caretakers, and providers is paramount to long-term adherence to treatment.

AB - Episode-based payment bundles a single lumped payment around a health care event, such as ischemic stroke. Hospitals are already experienced with a type of episode based payment for stroke, the diagnosis-related group payment system. Ischemic stroke fits well into an episode-based system because (1) ischemic stroke is common, (2) an ischemic stroke care episode lasts for a definable period of time, and (3) ischemic stroke care costs are high and episode-based payment could provide savings. In an episode-based ischemic stroke care payment system built around cost savings, it is unclear whether neurologists would provide savings. Neurologists need to prove, and define, the value they bring to ischemic stroke care. PMID- 29473571 TI - An elusive brain death diagnosis: You can't get there from here.

AB - Responding to requests from attorneys concerning patients or providing independent consultations in the legal process may present unique challenges, particularly if special reports are needed or if there is to be testimony under oath. While the legal process is adversarial, the role of the physician consultant, whether acting as treating physician or independent expert, is not to advocate for one side or the other, or to persuade the trier of fact, but to state his or her professional opinion clearly and concisely. The American Academy of Neurology published a position statement on "Qualifications and Guidelines for the Physician Expert Witness" in 2005. Following professional practice guidelines allows the neurologist to participate in the legal process effectively and ethically. The larger the pool of neurologists available for consultation in legal matters, the more access the legal system will have to balanced expertise.

This article provides an approach to the patient with sleep complaints that can be implemented during the course of a neurologic evaluation. Recognition of a sleep complaint is the key that leads to use of appropriate scales and sleep diaries to form a differential sleep diagnosis. Choosing the correct sleep test is essential to confirm diagnosis and plan therapy. We describe the important sleep tests for practicing neurologists: polysomnography, multiple sleep latency test, and maintenance of wakefulness test, as well as actigraphy and oximetry. The approved use of limited channel home tests (also known as "out of center testing," or "portable monitoring") is reviewed and an algorithm provided to guide the approach to the sleepy patient.

AB - Insomnia occurs in one-fourth to one-third of patients with dementia, and can lead to patient and caretaker distress and early institutionalization. An array of effects from the disease, medication, behaviors, and mood issues may play a role in influencing sleep. This perplexing issue can be handled effectively with appropriate evaluation and understanding of basic sleep-wake physiology. For most patients, appropriate timing of cues, modifying behavior, and optimizing medications can improve the patient's and caregiver's quality of life. In this article, we review signs that may help the clinician recognize insomnia early and approach the issue in a logical manner. PMID- 29473587 TI - Sleep medicine practice adaptations.

In addition, we offer advice to clinicians on how to review their customary office procedures and involve patients in overcoming administrative obstacles to the diagnostic and therapeutic course agreed upon by a doctor and patient. PMID- 29473588 TI - Diagnosis and management of periodic hypothermia. AB - Hypothermia, defined as a core temperature below 35 degrees C, can occur in a variety of clinical settings, including environmental exposure, shock, infection, metabolic disorders (such as hypothyroidism, adrenal insufficiency, and Wernicke encephalopathy), malnutrition, and alcohol or drug toxicity. Typically, hypothermia should resolve with treatment of the underlying disorder. However, in rare cases patients experience recurrent episodes of hypothermia in the context of a stereotyped syndrome due to a hypothalamic lesion, which can be either congenital or acquired. The episodes are characterized by progressive confusion and a decreased level of arousal, hypothermia, and eventual resolution with a return to baseline. Additional clinical findings during episodes may include diaphoresis, asterixis, bradycardia, and thrombocytopenia. These recurrent episodes represent periodic hypothermia.

AB - Otherwise benign MRI findings (so-called "incidentalomas") are a frequent cause of worry on the part of both clinician and patient. Knowledge of the imaging characteristics of incidentalomas, their (typically slight) pathologic significance, and how to distinguish these from less benign pathologic mimics can help avoid unnecessary worry, expense, and workup.

The guideline update reaffirms the efficacy of VNS for intractable epilepsy. Whereas it upholds the value of VNS for its originally approved indications, the guideline reminds us of existing evidence gaps and unmet research needs. This companion identifies ambiguities in the definition of intractable epilepsies and discusses the use of VNS in children under age 12 years and in persons with intellectual disabilities (mental retardation). Many payers require prior authorization and fulfillment of criteria for coverage of VNS. This article provides guidance and background information to reduce obstacles for coverage, especially where uncertainties exist and levels of evidence are lower.

AB - The purchase, implementation, and maintenance of an electronic health record (EHR) are among the most significant financial investments a practice will make. A practice's choice of EHR will have long-term and wide-ranging implications for how that practice operates. A successful EHR implementation may potentially result in increased efficiency, improved quality of patient care, and a possibly more successful practice. Extensive research and thoughtful planning, done with the involvement of all stakeholders, the commitment of adequate time, staff, and financial resources to the process, and sufficient training will increase the chances for a successful EHR implementation. PMID- 29473600 TI - Osteoporosis for the practicing neurologist. AB - Osteoporosis is a common condition of impaired bone strength leading to fractures. A targeted history, physical exam, and blood work can help elucidate potentially reversible causes of low bone mass. In the neurology office, particular attention should be paid to the patient on glucocorticoids or antiepileptic medications, as these have distinct detrimental effects on bone. Patients can be risk-stratified by using the FRAX calculator, a tool that can help determine whether the patient is at sufficient risk of fracture to warrant pharmacologic therapy. Nonpharmacologic treatments such as calcium, vitamin D, and exercise should be discussed with the patient. The cornerstone of pharmacologic therapy has been treatment with bisphosphonates, but newer medications are available as well for the high-risk patient. PMID- 29473601 TI - Emerging devices for epilepsy. AB - About 30% of people with epilepsy continue to have seizures despite a growing array of antiseizure drugs. For some of these people, surgical resection of brain tissue is an effective therapeutic option. For others, the likelihood of seizure freedom is low, and has not improved much despite the introduction of several new antiseizure drugs. The vagus nerve stimulator is the only device approved by the Food and Drug Administration (FDA), but it rarely results in freedom from seizures. Recently, 2 approaches to electrical stimulation of the brain have been reported. One device has been approved for use in Canada and in Europe, and it seems likely that one or more such devices will be approved for use in the United States. We examine some of the data from these studies in the context of the current FDA-approved drugs and devices.

AB - The role of neuroimaging in the assessment of a first-ever seizure has not been well-defined, in particular the utility of MRI when CT is normal. The results of neuroimaging (CT brain, MRI brain, or both) in 1,013 adults with first-ever unprovoked seizure were correlated with clinical features and seizure outcome. Epileptogenic lesions were identified in 29%. Of patients with a normal CT who also had MRI, 12% had an epileptogenic lesion on MRI, the strongest independent predictor of which was a focal abnormality on EEG. Patients with an epileptogenic lesion had a higher risk of seizure recurrence, including when this was only evident on MRI. PMID- 29473605 TI - Rare and treatable cause of progressive visual loss. PMID- 29473606 TI - Homonymous hemianopia in nonketotic hyperglycemia is an ictal phenomenon. AB - Extended video-EEG or 18F-fluorodeoxyglucose PET (FDG-PET) was obtained in 3 adult patients with hemianopia secondary to nonketotic hyperglycemia. Two male patients presented with left hemianopia and episodic left gaze deviation and one male patient presented with right hemianopia and visual hallucinations. None of the 3 patients had a history of seizures or known epilepsy risk factors. All 3 patients were found to have elevated serum glucose (267 mg/dL, 320 mg/dL, and 487 mg/dL) without acidosis or urine ketones. In all 3 patients, video-EEG recorded recurrent ictal discharges originating from the posterior quadrant contralateral to their hemianopia. In 2 patients, FDG-PET demonstrated corresponding focal areas of hypermetabolism. Resolution of visual symptoms was achieved with antiepileptic drugs, hydration, and tight glycemic control.

AB - Intravenous immunoglobulin (IVIg) has been widely used in the treatment of autoimmune neuromuscular diseases. Compared to other treatment modalities, such as corticosteroids and chemotherapy for autoimmune disorders, IVIg has relatively few side effects and favorable therapeutic outcomes in certain neuromuscular diseases. There is Class I evidence for IVIg as an initial treatment for patients with Guillain-Barre syndrome (GBS), chronic inflammatory demyelinating polyneuropathy (CIDP), and multifocal motor neuropathy. It is as effective as plasma exchange in GBS and CIDP. In myasthenia gravis, IVIg is used for myasthenic crisis and exacerbations, though it is also helpful as maintenance therapy, particularly in patients with a suboptimal response or contraindications to prednisone or other immunosuppressive agents. IVIg has been demonstrated to be beneficial in placebo-controlled, double-blind, randomized studies in dermatomyositis and Lambert-Eaton syndrome. IVIg has also been beneficial in select patients with polymyositis and other autoimmune peripheral neuropathies. Clinical trials in amyotrophic lateral sclerosis, inclusion body myositis, and anti-myelin-associated glycoprotein neuropathy have been negative.

Neurologists are often consulted to evaluate patients with postoperative symptoms and must be ready to discriminate those truly caused by the anesthetic drug or procedure from the more common postoperative complications that are unrelated to the anesthesia itself. This practical review relies on cases to illustrate common reasons for neurologic consultation in the postsurgical setting. It also briefly summarizes what to expect when patients with central or peripheral neurologic disease undergo surgery under general or regional anesthesia.

Although improvements in the recognition and management of MS have been made in recent years, challenges remain due to the complex nature of the disease. Clinicians must remain current with their skills as knowledge surrounding MS care continues to advance. Here we report results of a performance improvement (PI) continuing medical education (CME) activity that was designed to promote evidence-based care of patients with MS. Participants demonstrated significant improvements in assessing disease related complications, treating cognitive dysfunction, assessing adherence, and providing disease-related educational materials. These data support the role of PI CME in improving clinician practices that align with quality MS patient care.

AB - Dimethyl fumarate (DMF) is the latest oral therapy approved for relapsing remitting multiple sclerosis (RRMS). In 2 placebo-controlled phase III trials, twice daily DMF demonstrated a 44%-53% reduction in annualized relapse rate and 71%-90% reduction in new MRI lesions. In one trial, DMF slowed the accumulation of disability, but not in the other trial. The main side effects of DMF include gastrointestinal symptoms (nausea, abdominal pain, vomiting, and diarrhea) and skin flushing, which peak at treatment initiation. There was no increased risk of opportunistic infections. Recommended safety monitoring includes complete blood count prior to treatment and annually while on treatment. Appealing aspects of DMF include potent efficacy, oral administration, and good safety and tolerability profiles. Altogether, DMF is an attractive option for first-line treatment, breakthrough disease activity, intolerance to other therapies, and possibly natalizumab-treated patients with positive JC virus serology. PMID- 29473632 TI - Capturing incentives and avoiding penalties: The carrot and the stick. AB - Over the past decade, health care in the United States has been a topic of intense political debate, resulting in dramatic legislative, regulatory, and economic changes. These changes have occurred due to the unsustainable rise of health care costs without accompanying improvement in measured health outcomes when compared to other economically developed countries. In an attempt to contain costs and improve the quality of health care provided, the Center for Medicare and Medicaid Services has implemented 4 distinct incentive-based programs. Data are scarce concerning whether such programs will be successful in accomplishing these goals. Each health care provider will need to weigh the costs of participation against the fines incurred by nonparticipation (up to 10% of annual Medicare payments). Knowledge of the percentage of one's practice dedicated to the care of patients in the Medicare and Medicaid programs will be helpful in arriving at a final decision.

AB - Only 1%-5% of patients with acute ischemic stroke presenting within 3 hours of symptoms receive IV recombinant tissue plasminogen activator (rtPA)-the only effective treatment available. The administration of rtPA is limited by extensive exclusion criteria, many of which are not based on evidence, but rather derived from expert opinion for large stroke trials. Over the past 15 years, experiences with the use of rtPA in clinical practice have led to evidence suggesting that several of the current contraindications for rtPA are unnecessary and overly restrictive. In this review, we analyze the evidence-most of which is derived from observational research-supporting or contradicting current contraindications for administering IV rtPA to acute ischemic stroke patients.

PMID- 29473645 TI - Locomotor activity, growth hormones, and systemic robusticity: An investigation of cranial vault thickness in mouse lines bred for high endurance running. AB - OBJECTIVES: To use a mouse model to investigate the relationships among the components of the systemic robusticity hypothesis (SRH): voluntary exercise on wheels, spontaneous physical activity (SPA) in cages, growth hormones, and skeletal robusticity, especially cranial vault thickness (CVT). MATERIALS AND METHODS: Fifty female mice from lines artificially selected for high running (HR) and 50 from nonselected control (C) lines were housed in cages with (Active) or without wheels (Sedentary). Wheel running and SPA were monitored daily. The experiment began at 24-27 days of age and lasted 12 weeks. Food consumption was measured weekly. Mice were skeletonized and their interparietal, parietal, humerus, and femur were uCT scanned. Mean total thickness of the parietal and interparietal bones was determined, along with thickness of the cortical and diploe layers individually. Geometric cross-sectional indicators of strength were calculated for the long bones. Blood samples were assayed for IGF-1 and IGFBP-3. RESULTS: Physical activity differed significantly among groups, based both on linetype (C vs. HR) and activity (A vs. S). However, contrary to our predictions, the ratio of IGF-1 to IGFBP-3 was higher in C mice than in HR mice. Neither CVT nor postcranial robusticity was affected by linetype or activity, nor were most measures of CVT and postcranial robusticity significantly associated with one another. DISCUSSION: Our results fail to provide support for the systemic robusticity hypothesis, suggesting it is important to rethink the long-standing theory that increased CVT in Homo erectus reflects increased physical activity compared other hominin species. PMID- 29473644 TI - The Atrial Fibrillation Health Literacy Information Technology System: Pilot Assessment. AB - Background: Atrial fibrillation (AF) is a highly prevalent heart rhythm condition that has significant associated morbidity and requires chronic treatment. Mobile health (mHealth) technologies have the potential to enhance multiple aspects of AF care, including education, monitoring of symptoms, and encouraging and tracking medication adherence. We have previously implemented and tested relational agents to improve outcomes in chronic disease and sought to develop a smartphone-based relational agent for improving patient-centered outcomes in AF. Objective: The objective of this study was to pilot a smartphone-based relational agent as preparation for a randomized clinical trial, the Atrial Fibrillation Health Literacy Information Technology Trial (AF-LITT). Methods: We developed the relational agent for use by a smartphone consistent with our prior approaches. We programmed the relational agent as a computer-animated agent to simulate a face to-face conversation and to serve as a health counselor or coach specific to AF. Relational agent's dialogue content, informed by a review of literature, focused on patient-centered domains and qualitative interviews with patients with AF, encompassed AF education, common symptoms, adherence challenges, and patient activation. We established that the content was accessible to individuals with limited health or computer literacy. Relational agent content coordinated with use of the smartphone AliveCor Kardia heart rate and rhythm monitor. Participants (N=31) were recruited as a convenience cohort from ambulatory clinical sites and instructed to use the relational agent and Kardia for 30 days. We collected demographic, social, and clinical characteristics and conducted baseline and 30 day assessments of health-related quality of life (HRQoL) with the Atrial Fibrillation Effect on Quality of life (AFEQT) measure; self-reported medication adherence with the Morisky 8-item Medication Adherence Scale (MMAS-8); and patient activation with the Patient Activation Measure (PAM). Results: Participants (mean age 68 [SD 11]; 39% [12/31] women) used the relational agent for an average 17.8 (SD 10.0) days. The mean number of independent log-ins was 19.6 (SD 10.7), with a median of 20 times over 30 days. The mean number of Kardia uses was 26.5 (SD 5.9), and participants using Kardia were in AF for 14.3 (SD 11.0) days. AFEQT scores improved significantly from 64.5 (SD 22.9) at baseline to 76.3 (SD 19.4) units at 30 days (P<.01). We observed marginal but statistically significant improvement in self-reported medication adherence (baseline: 7.3 [SD 0.9], 30 days: 7.7 [SD 0.5]; P=.01). Assessments of acceptability identified that most of the participants found the relational agent useful, informative, and trustworthy. Conclusions: We piloted a 30-day smartphone based intervention that combined a relational agent with dedicated content for AF alongside Kardia heart rate and rhythm monitoring. Pilot participants had favorable improvements in HRQoL and self-reported medication adherence, as well as positive responses to the intervention. These data will guide a larger, enhanced randomized trial implementing the smartphone relational agent and the Kardia monitor system. PMID- 29473647 TI - Potential virulence factors of bacteria associated with tail fan necrosis in the spiny lobster, Jasus edwardsii. AB - Tail fan necrosis (TFN) is a common condition found in commercially exploited spiny lobsters that greatly diminishes their commercial value. Bacteria possessing proteolytic, chitinolytic and lipolytic capabilities were associated with TFN in spiny lobsters, Jasus edwardsii. In this study, 69 bacterial isolates exhibiting all the three enzymatic capabilities from the haemolymph and tail fans of J. edwardsii with and without TFN were further characterized and compared, including morphology, biofilm formation, antimicrobial activity, antimicrobial resistance, and production of siderophores, melanin and ammonia. The genomic patterns of the most common Vibrio crassostreae isolates were also compared between TFN-affected and unaffected lobsters. Biofilm formation was stronger in bacterial isolates from both haemolymph and tail fans of TFN-affected lobsters compared to those from the unaffected lobsters, while melanin production and siderophore production were stronger in the isolates from tail fans of lobsters with TFN. By contrast, the other characteristics of isolates were similar in lobsters with and without TFN. The Vib. crassostreae isolates from the affected lobsters had similar genomic patterns. Overall, the results indicate that in addition to proteolytic, chitinolytic and lipolytic activities, the bacteria associated with TFN commonly have enhanced activity of important virulence factors, including biofilm formation, melanin production and siderophore production.

PMID- 29473646 TI - Research Review: Intergenerational transmission of disadvantage: epigenetics and parents' childhoods as the first exposure. AB - BACKGROUND: For decades, economists and sociologists have documented intergenerational transmission of socioeconomic disadvantage, demonstrating that economic, political, and social factors contribute to 'inherited hardship'. Drawing on biological factors, the developmental origins of adult health and disease model posits that fetal exposure to maternal prenatal distress associated with socioeconomic disadvantage compromises offspring's neurodevelopment, affecting short- and long-term physical and mental health, and thereby psychosocial standing and resources. Increasing evidence suggests that mother-to child influence occurs prenatally, in part via maternal and offspring atypical HPA axis regulation, with negative effects on the maturation of prefrontal and subcortical neural circuits in the offspring. However, even this in utero timeframe may be insufficient to understand biological aspects of the transmission of factors contributing to disadvantage across generations. METHODS: We review animal studies and emerging human research indicating that parents' childhood experiences may transfer epigenetic marks that could impact the development of their offspring independently of and in interaction with their offspring's perinatal and early childhood direct exposures to stress stemming from socioeconomic disadvantage and adversity. RESULTS: Animal models point to epigenetic mechanisms by which traits that could contribute to disadvantage may be transmitted across generations. However, epigenetic pathways of parental childhood experiences influencing child outcomes in the next generation are only beginning to be studied in humans. With a focus on translational research, we point to design features and methodological considerations for human cohort studies to be able to test the intergenerational transmission hypothesis, and we illustrate this with existing longitudinal studies. CONCLUSIONS: Epigenetic intergenerational transmission, if at play in human populations, could have policy implications in terms of reducing the continuation of disadvantage across generations. Further research is needed to address this gap in the understanding of the perpetuation of compromised lives across generations. PMID- 29473649 TI - Detection of tilapia lake virus (TiLV) infection by PCR in farmed and wild Nile tilapia (Oreochromis niloticus) from Lake Victoria. AB - Tilapia lake virus disease (TiLVD) has emerged to be an important viral disease of farmed Nile tilapia (Oreochromis niloticus) having the potential to impede expansion of aquaculture production. There is a need for rapid diagnostic tools to identify infected fish to limit the spread in individual farms. We report the first detection of TiLV infection by PCR in farmed and wild Nile tilapia from Lake Victoria. There was no difference in prevalence between farmed and wild fish samples (p = .65), and of the 442 samples examined from 191 fish, 28 were positive for TiLV by PCR. In terms of tissue distribution, the head kidney (7.69%, N = 65) and spleen (10.99%, N = 191), samples had the highest prevalence (p < .0028) followed by heart samples (3.45%, N = 29). Conversely, the prevalence was low in the liver (0.71%, N = 140) and absent in brain samples (0.0%, N = 17), which have previously been shown to be target organs during acute infections. Phylogenetic analysis showed homology between our sequences and those from recent outbreaks in Israel and Thailand. Given that these findings were based on nucleic acid detection by PCR, future studies should seek to isolate the virus from fish in Lake Victoria and show its ability to cause disease and virulence in susceptible fish. PMID- 29473650 TI - Lipid catabolism in microalgae. AB - Lipid degradation processes are important in microalgae because survival and growth of microalgal cells under fluctuating environmental conditions require permanent remodeling or turnover of membrane lipids as well as rapid mobilization of storage lipids. Lipid catabolism comprises two major spatially and temporarily separated steps, namely lipolysis, which releases fatty acids and head groups and is catalyzed by lipases at membranes or lipid droplets, and degradation of fatty acids to acetyl-CoA, which occurs in peroxisomes through the beta-oxidation pathway in green microalgae, and can sometimes occur in mitochondria in some other algal species. Here we review the current knowledge on the enzymes and regulatory proteins involved in lipolysis and peroxisomal beta-oxidation and highlight gaps in our understanding of lipid degradation pathways in microalgae. Metabolic use of acetyl-CoA products via glyoxylate cycle and gluconeogenesis is also reviewed. We then present the implication of various cellular processes such as vesicle trafficking, cell cycle and autophagy on lipid turnover. Finally, physiological roles and the manipulation of lipid catabolism for biotechnological applications in microalgae are discussed. PMID- 29473651 TI - Phenolic root exudate and tissue compounds vary widely among temperate forest tree species and have contrasting effects on soil microbial respiration. AB - Root-soil interactions fundamentally affect the terrestrial carbon (C) cycle and thereby ecosystem feedbacks to climate change. This study addressed the question of whether the secondary metabolism of different temperate forest tree species can affect soil microbial respiration. We hypothesized that phenolics can both increase and decrease respiration depending on their function as food source, mobilizer of other soil resources, signaling compound, or toxin. We analyzed the phenolic compounds from root exudates and root tissue extracts of six tree species grown in a glasshouse using high-performance liquid chromatography. We then tested the effect of individual phenolic compounds, representing the major identified phenylpropanoid compound classes, on microbial respiration through a 5 d soil incubation. Phenolic root profiles were highly species-specific. Of the eight classes identified, flavonoids were the most abundant, with flavanols being the predominating sub-class. Phenolic effects on microbial respiration ranged from a 26% decrease to a 46% increase, with reduced respiration occurring in the presence of compounds possessing a catechol ring. Tree species variation in root phenolic composition influences the magnitude and direction of root effects on microbial respiration. Our data support the hypothesis that functional group rather than biosynthetic class determines the root phenolic effect on soil C cycling. PMID- 29473652 TI - In Vitro Evaluation of ECG-Synchronized Pulsatile Flow Using the i-cor Diagonal Pump in Neonatal and Pediatric ECLS Systems. AB - The objective was to assess the i-cor electrocardiogram-synchronized diagonal pump in terms of hemodynamic energy properties for off-label use in neonatal and pediatric extracorporeal life support (ECLS) circuits. The neonatal circuit consisted of an i-cor pump and console, a Medos Hilite 800 LT oxygenator, an 8Fr arterial cannula, a 10Fr venous cannula, 91 cm of 0.6-cm ID arterial tubing, and 91 cm of 0.6-cm ID venous tubing. The pediatric circuit was identical except it included a 12Fr arterial cannula, a 14Fr venous cannula, and a Medos Hilite 2400 LT oxygenator. Neonatal trials were conducted at 36 degrees C with hematocrit 40% using varying flow rates (200-600 mL/min, 200 mL increments) and postarterial cannula pressures (40-100 mm Hg, 20 mm Hg increments) under nonpulsatile mode and pulsatile mode with various pulsatile amplitudes (1000-4000 rpm, 1000 rpm increments). Pediatric trials were conducted at different flow rates (800-1600 mL/min, 400 mL/min increments). Mean pressure and energy equivalent pressure increased with increasing postarterial cannula pressure, flow rate, and pulsatile amplitude. Physiologic-like pulsatility was achieved between pulsatile amplitudes of 2000-3000 rpm. Pressure drops were greatest across the arterial cannula. Pulsatile flow generated significantly higher total hemodynamic energy (THE) levels than nonpulsatile flow. THE levels at postarterial cannula site increased with increasing postarterial cannula pressure, pulsatile amplitude, and flow rate. No surplus hemodynamic energy (SHE) was generated under nonpulsatile mode. Under pulsatile mode, preoxygenator SHE increased with increasing postarterial cannula pressure and pulsatile amplitude, but decreased with increasing flow rate. The i-cor system can provide nonpulsatile and pulsatile flow for neonatal and pediatric ECLS. Pulsatile amplitudes of 2000-3000 rpm are recommended for use in neonatal and pediatric patients. PMID- 29473653 TI - Manipulating parameters of reinforcement to reduce problem behavior without extinction. AB - Differential reinforcement of alternative behavior (DRA) most often includes extinction as a treatment component. However, extinction is not always feasible and it can be counter-therapeutic if implemented without optimal treatment integrity. Researchers have successfully implemented DRA without extinction by manipulating various parameters of reinforcement such that alternative behavior is favored. We extended previous research by assessing three participants' sensitivities to quality, magnitude, and immediacy using arbitrary responses and reinforcers that maintain problem behavior. The results were used to implement an intervention for problem behavior using DRA without extinction. Our findings indicate that arbitrary responses can be used to identify individual and relative sensitivity to parameters of reinforcement for reinforcers that maintain problem behavior. Treatment was effective for all participants when we manipulated parameters of reinforcement to which they were most sensitive, and, for two participants, the treatment was less effective when we manipulated parameters to which they were least sensitive. PMID- 29473654 TI - Using equivalence-based instruction to teach piano skills to college students. AB - The purpose of the current study was to evaluate the effects of equivalence-based instruction (EBI) on the emergence of basic music reading and piano playing skills. Six female college students learned to identify three musical chord notations given their respective dictated names. Participants also learned to play chords on the piano following the dictated name of the chord, and to play the chords to a song on a keyboard. Results are consistent with past research, in that stimuli became substitutable for each other and acquired a common behavioral function. Data suggest that EBI was an effective and efficient procedure to teach adults to read musical notation, as well as play chords and a song on a piano keyboard. PMID- 29473655 TI - Characterization of the genetic factors affecting quinolizidine alkaloid biosynthesis and its response to abiotic stress in narrow-leafed lupin (Lupinus angustifolius L.). AB - Quinolizidine alkaloids (QAs) are toxic secondary metabolites that complicate the end use of narrow-leafed lupin (NLL; Lupinus angustifolius L.) grain, as levels sometimes exceed the industry limit for its use as a food and feed source. The genotypic and environmental influences on QA production in NLL are poorly understood. Here, the expression of QA biosynthetic genes was analysed in vegetative and reproductive tissues of bitter (high QA) and sweet (low QA) accessions. It was demonstrated that sweet accessions are characterized by lower QA biosynthetic gene expression exclusively in leaf and stem tissues than bitter NLL, consistent with the hypothesis that QAs are predominantly produced in aerial tissues and transported to seeds, rather than synthesized within the seed itself. This analysis informed our identification of additional candidate genes involved in QA biosynthesis. Drought and temperature stress are two major abiotic stresses that often occur during NLL pod set. Hence, we assessed the effect of drought, increased temperature, and their combination, on QA production in three sweet NLL cultivars. A cultivar-specific response to drought and temperature in grain QA levels was observed, including the identification of a cultivar where alkaloid levels did not change with these stress treatments.

We explored whether this variant modulates the L2PD age at onset in Spain. METHODS: We genotyped rs2421947 in 329 participants (210 L2PD patients, 119 L2PD nonmanifesting p.G2019S carriers), and marker rs356219 (A/G) in the alpha-synuclein gene (SNCA). RESULTS: By Kaplan Meier and Cox regression analyses, we did not find an association of the DNM3 polymorphism with L2PD age at onset. However, we found an association of the SNCA marker with up to an 11 years difference in the L2PD median age at onset (58 years for GG carriers vs 69 years for AA). CONCLUSION: Our results indicate that SNCA rs356219 but not dynamin 3 DNM3 rs2421947 modifies the penetrance of the mutation G2019S in the Spanish population by influencing the L2PD age at onset. These findings suggest that different genetic modifiers may influence the L2PD age at onset in different populations. (c) 2018 International Parkinson and Movement Disorder Society. PMID- 29473657 TI - Fermentable short chain carbohydrate (FODMAP) content of common plant-based foods and processed foods suitable for vegetarian- and vegan-based eating patterns. AB - BACKGROUND: The low FODMAP (fermentable, oligo-, di-, mono-saccharides and polyols) diet is an effective strategy to improve symptoms of irritable bowel syndrome. However, combining the low FODMAP diet with another dietary restriction such as vegetarianism/veganism is challenging. Greater knowledge about the FODMAP composition of plant-based foods and food processing practices common to vegetarian/vegan eating patterns would assist in the implementation of the diet in this patient population. The present study aimed to quantify the FODMAP content of plant-based foods common in vegetarian/vegan diets and to investigate whether food processing can impact FODMAP levels. METHODS: Total FODMAP content was quantified in 35 foods, including fructose-in-excess-of-glucose, lactose, sorbitol, mannitol, galacto-oligosaccharide and total fructan, using high performance-liquid-chromatography and enzymatic assays. The effects of cooking, sprouting, pickling, fermentation, activation and canning on FODMAP content were assessed. The Monash University criteria to classify foods as low FODMAP was used. RESULTS: Of the 35 foods, 20 were classified as low FODMAP, including canned coconut milk (0.24 g serve-1 ), dulse (0.02 serve-1 ), nutritional yeast (0.01 serve-1 ), soy cheese (0.03 serve-1 ), tempeh (0.26 serve-1 ), wheat gluten (0.13 serve-1 ) and wheat grass (0.05 serve-1 ). No FODMAPs were detected in agar agar, egg replacer, vegan egg yolk, kelp noodles and spirulina. Food processing techniques that produced the greatest reduction in FODMAP content included pickling and canning. CONCLUSIONS: The present study provides a greater FODMAP composition knowledge of plant-based foods that can now be applied to the dietetic management of vegetarians/vegans requiring a low FODMAP diet. Food processing lowered the FODMAP content of foods, thereby increasing options for patients following a low FODMAP diet.

AB - Since the 1980s, gadolinium (Gd)-based contrast agents (GBCAs) have been routinely used in magnetic resonance imaging as stable chelates of the Gd3+ ion, without toxic effects. Generally, GBCAs are considered some of the safest contrast agents. However, it has been observed that they can accumulate in patient tissue, bone, and probably brain (causing nephrogenic systemic fibrosis in patients with kidney failure or insufficiency and disturbance of calcium homeostasis in the organism). The GBCAs are predominantly removed renally without metabolization. Subsequently, they do not undergo degradation processes in wastewater-treatment plants and are emitted into the aquatic ecosystem. Their occurrence was confirmed in surface waters (up to 1100 ng/L), sediments (up to 90.5 MUg/g), and living organisms. Based on a literature review, there is a need to investigate the contamination of different ecosystems and to ascertain the environmental fate of Gd. Long-term ecotoxicological data, degradation, metabolism, bioaccumulation processes, and biochemical effects of the Gd complexes should be explored. These data can be used to assess detailed environmental risks because currently only hotspots with high levels of Gd can be marked as dangerous for aquatic environments according to environmental risk assessments.

AB - Detection of hypochlorous acid (HClO) in the living system may help to uncover its essential biological functions. However, current imaging agents suffer from poor water solubility that limit their live-tissue applications. Here, a water soluble probe (NNH) is devised through innovative hydrazone modification of 1,8 naphthalimide at 3' position. NNH was successfully applied to tracking endogenous HClO in both cultured macrophages and a liver injury model in mice. NNH demonstrated remarkably increased water solubility and multiple desirable features including two-photon absorbance, anti-bleaching capability, rapid cellular uptake, and low cytotoxicity. NNH is the first hydrazone-based probe for real-time imaging of HClO in live tissue. PMID- 29473660 TI - Direct and indirect pathways for choosing objects and actions. AB - A prominent target of the basal ganglia is the superior colliculus (SC) which controls gaze orientation (saccadic eye movement in primates) to an important object. This 'object choice' is crucial for choosing an action on the object. SC is innervated by the substantia nigra pars reticulata (SNr) which is controlled mainly by the caudate nucleus (CD). This CD-SNr-SC circuit is sensitive to the values of individual objects and facilitates saccades to good objects. The object values are processed differently in two parallel circuits: flexibly by the caudate head (CDh) and stably by the caudate tail (CDt). To choose good objects, we need to reject bad objects. In fact, these contrasting functions are accomplished by the circuit originating from CDt: The direct pathway focuses on good objects and facilitates saccades to them; the indirect pathway focuses on bad objects and suppresses saccades to them. Inactivation of CDt deteriorated the object choice, because saccades to bad objects were no longer suppressed. This suggests that the indirect pathway is important for object choice. However, the direct and indirect pathways for 'object choice', which aim at the same action (i.e., saccade), may not work for 'action choice'. One possibility is that circuits controlling different actions are connected through the indirect pathway. Additional connections of the indirect pathway with brain areas outside the basal ganglia may also provide a wider range of behavioral choice. In conclusion, basal ganglia circuits are composed of the basic direct/indirect pathways and additional connections and thus have acquired multiple functions.

AB - BACKGROUND: Multimodal MRI approach is based on a combination of MRI parameters sensitive to different tissue characteristics (eg, volume atrophy, iron deposition, and microstructural damage). The main objective of the present study was to use a multimodal MRI approach to identify brain differences that could discriminate between matched groups of patients with multiple system atrophy, Parkinson's disease, and healthy controls. We assessed the 2 different MSA variants, namely, MSA-P, with predominant parkinsonism, and MSA-C, with more prominent cerebellar symptoms. METHODS: Twenty-six PD patients, 29 MSA patients (16 MSA-P, 13 MSA-C), and 26 controls underwent 3-T MRI comprising T2*-weighted, T1-weighted, and diffusion tensor imaging scans. Using whole-brain voxel-based MRI, we combined gray-matter density, T2* relaxation rates, and diffusion tensor imaging scalars to compare and discriminate PD, MSA-P, MSA-C, and healthy controls. RESULTS: Our main results showed that this approach reveals multiparametric modifications within the cerebellum and putamen in both MSA-C and MSA-P patients, compared with PD patients. Furthermore, our findings revealed that specific single multimodal MRI markers were sufficient to discriminate MSA-P and MSA-C patients from PD patients. Moreover, the unsupervised analysis based on multimodal MRI data could regroup individuals according to their clinical diagnosis, in most cases. CONCLUSIONS: This study demonstrates that multimodal MRI is able to discriminate patients with PD from those with MSA with high accuracy. The combination of different MR biomarkers could be a great tool in early stage of disease to help diagnosis. (c) 2018 International Parkinson and Movement Disorder Society. PMID- 29473663 TI - Long-term clinicopathologic observation in a case of steroid-resistant nephrotic syndrome caused by a novel Crumbs homolog 2 mutation. AB - Recent advances in high-throughput sequencing for clinical genetic testing have revealed novel disease-causing genes, such as Crumbs homolog 2 (CRB2) for early onset steroid-resistant nephrotic syndrome (SRNS). We report the long-term clinicopathologic observation of a Japanese female patient with SRNS caused by a newly identified compound heterozygous mutation of CRB2 (p.Arg628Cys and p.Gly839Trp located in the 10th and 11th epidermal growth factor-like domains, respectively). She was initially examined during a mass urinary screening for 3.5 year-old children in Japan. Although she developed long-standing SRNS without any extrarenal clinical signs thereafter, her renal function was well-preserved over the next 17 years. In total, six sequential renal biopsy specimens revealed histologic alterations ranging from minor glomerular abnormalities to advanced focal segmental glomerulosclerosis (FSGS). A genetic analysis for SRNS performed at 19 years of age revealed a newly identified compound heterozygous mutation in CRB2. Glomerular CRB2 immunoreactivity in biopsy specimens from the patient was scanty, whereas intense expression was observed in those from patients with idiopathic FSGS or in controls. To our knowledge, this is the first report regarding a long-term outcome in a case of SRNS due to an identified CRB2 mutation. Although the phenotype of CRB2 mutation-related syndrome is now expanding, we believe that this case might provide a novel clinicopathologic aspect of this syndrome. PMID- 29473661 TI - Facial emotion recognition in Parkinson's disease: A review and new hypotheses. AB - Parkinson's disease is a neurodegenerative disorder classically characterized by motor symptoms. Among them, hypomimia affects facial expressiveness and social communication and has a highly negative impact on patients' and relatives' quality of life. Patients also frequently experience nonmotor symptoms, including emotional-processing impairments, leading to difficulty in recognizing emotions from faces. Aside from its theoretical importance, understanding the disruption of facial emotion recognition in PD is crucial for improving quality of life for both patients and caregivers, as this impairment is associated with heightened interpersonal difficulties. However, studies assessing abilities in recognizing facial emotions in PD still report contradictory outcomes. The origins of this inconsistency are unclear, and several questions (regarding the role of dopamine replacement therapy or the possible consequences of hypomimia) remain unanswered. We therefore undertook a fresh review of relevant articles focusing on facial emotion recognition in PD to deepen current understanding of this nonmotor feature, exploring multiple significant potential confounding factors, both clinical and methodological, and discussing probable pathophysiological mechanisms. This led us to examine recent proposals about the role of basal ganglia-based circuits in emotion and to consider the involvement of facial mimicry in this deficit from the perspective of embodied simulation theory. We believe our findings will inform clinical practice and increase fundamental knowledge, particularly in relation to potential embodied emotion impairment in PD. (c) 2018 The Authors.

AB - Herein, we reported a general protocol for an ab initio modeling approach to deduce structure information of polyoxometalates (POMs) in solutions from scattering data collected by the small-angle X-ray scattering (SAXS) technique. To validate the protocol, the morphologies of a serious of known POMs in either aqueous or organic solvents were analyzed. The obtained particle morphologies were compared and confirmed with previous reported crystal structures. To extend the feasibility of the protocol to an unknown system of aqueous solutions of Na2 MoO4 with the pH ranging from -1 to 8.35, the formation of {Mo36 } clusters was probed, identified, and confirmed by SAXS. The approach was further optimized with a multi-processing capability to achieve fast analysis of experimental data, thereby, facilitating in situ studies of formations of POMs in solutions. The advantage of this approach is to generate intuitive 3D models of POMs in solutions without confining information such as symmetries and possible sizes.

AB - This study quantified the contributions by muscular, gravitational and inertial forces to the ground reaction force (GRF) and external knee adduction moment (EKAM) for knee osteoarthritis (OA) patients and controls walking at similar speeds. Gait data for 39 varus mal-aligned medial knee OA patients and 15 controls were input into musculoskeletal models to calculate the contributions of individual muscles and gravity to the fore-aft (progression), vertical (support), and mediolateral (balance) GRF, and the EKAM. The temporal patterns of contributions to GRF and EKAM were similar between the groups. Magnitude differences in GRF contributions were small but some reached significance. Peak GRF contributions were lower in patients except hamstrings in early-stance progression (p < 0.001) and gastrocnemius in late-stance progression (p < 0.001). Both EKAM peaks were higher in patients, due mainly to greater adduction contribution from gravity (p < 0.001) at the first peak, and lower abduction contributions from soleus (p < 0.001) and gastrocnemius (p < 0.001) at the second peak. Gluteus medius contributed most to EKAM in both groups, but was higher in patients during mid-stance only (p < 0.001). Differences in GRF contributions were attributed to altered quadriceps-hamstrings action as well as compensatory adaptation of the ankle plantarflexors to reduced gluteus medius action. The large effect of varus mal-alignment on the frontal-plane moment arms of the gravity, soleus, and gastrocnemius GRF contributions about the knee explained greater patient EKAM. Our results shed further light on how the EKAM contributes to altered knee-joint loads in OA and why some interventions may affect different portions of the EKAM waveform.

AB - The current method of measuring arthrofibrosis in live rabbits is critically limited. Specifically, this method involves radioactive fluoroscopy, error-prone goniometric measurements, and static joint angle outcomes that fail to approximate the compliance of tissues surrounding the joint. This study aims to validate a novel method of capturing the compliance of contracted tissues surrounding the joint without the use of fluoroscopy or animal sacrifice. Surgically induced contractures of one-hundred and eight rabbits were measured using the current standard of contracture measurement (a pulley system) as well as a newly designed dynamic load cell (DLC) device. The DLC device was highly reliable when compared to the pulley system (r = 0.907, p < 0.001). Finally, the DLC device produced joint stiffness hysteresis curves capable of approximating the compliance of stiff joint tissues, ultimately calculating a mean joint stiffness of 1.57 +/- 1.31 N . m . rad-1 (range, 0.33-6.37 N . m . rad-1 ). In conclusion, the DLC device represents a valid method for measuring joint contractures. Further, the DLC device notably improves current techniques by introducing the capacity to approximate the compliance of contracted tissues in living rabbits. (c) 2018 Orthopaedic Research Society.

AB - The synthesis of carbon-based nanomaterials is often inefficient, generating large amounts of soot with metals as waste by-product. Currently, there are no specific regulations for disposal of engineered nanomaterials or the waste by products resulting from their synthesis, so it is presumed that by-products are disposed of in the same way as the parent (bulk) materials. We studied the terrestrial toxicity of soot from gadolinium metallofullerene nanomanufacturing on earthworms (Eisenia fetida) and isopods (Porcellio scaber). The metallofullerene soot consisted of carbon particle agglomerates in the nanometer and submicrometer ranges (1-100 and 101-999 nm, respectively), with metals used during nanomanufacturing detectable on the particles. Despite high metal concentrations (>100 000 mg/kg) in the soot, only a relatively small amount of metals leached out of a spiked field soil, suggesting only moderate mobility. Seven- and 14-d exposures in field soil demonstrated that the soot was only toxic to earthworms at high concentrations (>10 000 mg/kg); however, earthworms avoided spiked soils at lower concentrations (as low as 500 mg/kg) and at lower soil pH. The presence of soot in food and soil did not cause isopod avoidance. These data demonstrate that metallofullerene soot from nanomanufacturing may only be toxic to earthworms at high concentrations representative of improper disposal or accidental spills. However, our results indicate that terrestrial invertebrates may avoid soils contaminated with soot at sublethal concentrations. Environ Toxicol Chem 2018;9999:1-12.

PMID- 29473670 TI - Some assembly required: Contributions of Tom Stevens' lab to the V-ATPase field. AB - Tom Stevens' lab has explored the subunit composition and assembly of the yeast V ATPase for more than 30 years. Early studies helped establish yeast as the predominant model system for study of V-ATPase proton pumps and led to the discovery of protein splicing of the V-ATPase catalytic subunit. The Vma- phenotype, characteristic of loss-of-V-ATPase activity in yeast was key in determining the enzyme's subunit composition via yeast genetics. V-ATPase subunit composition proved to be highly conserved among eukaryotes. Genetic screens for new vma mutants led to identification of a set of dedicated V-ATPase assembly factors and helped unravel the complex pathways for V-ATPase assembly. In later years, exploration of the evolutionary history of several V-ATPase subunits provided new information about the enzyme's structure and function. This review highlights V-ATPase work in the Stevens' lab between 1987 and 2017. PMID- 29473672 TI - Fertility treatment: Getting stressed about stress.

AB - OBJECTIVES: Human subadult skeletal remains can provide a unique perspective into biosocial aspects of Mississippian period population interactions within and between the Middle Cumberland (MCR) and Eastern Tennessee Regions (ETR). The majority of previous studies have concentrated on adult skeletal remains, leaving out a large and extremely important population segment. METHODS: Skeletal indicators of disease, growth, body proportions, and metabolic stress were collected from subadult remains from five archaeological sites over several temporal periods. Crucial to overcoming limitations associated with the osteological paradox, the biological results were placed into an archaeological context based on prior studies as well as paleoclimatological data. RESULTS: Results reveal homogeneity both within and between regions for most skeletal indicators. However, MCR individuals exhibit a higher frequency of pathology than those from ETC, while stature is significantly lower in younger subadults from the MCR. Within the ETR, there is no evidence for biological differences between Early Dallas and subsequent Late Dallas and Mouse Creek cultural phases. Despite presumed signs of increased conflict at the Dallas site, frequencies and types of skeletal pathology and growth disruptions are comparable to other regional sites. CONCLUSIONS: These findings suggest that despite cultural differences between the ETR and MCR, there was no large-scale intrusion from an outside population into the ETR during the Late Mississippian Period, or if one occurred, it is biologically invisible. Combined with climatic and archaeobotanical data, results suggest the MCR subadults were under increased stress in their earlier years. This may have been associated with increased interpersonal violence and dependence on few food sources occurring with greater scarcity.

PMID- 29473675 TI - Contemporary Oxygenator Design: Shear Stress-Related Oxygen and Carbon Dioxide Transfer. AB - Design of contemporary oxygenators requires better understanding of the influence of hydrodynamic patterns on gas exchange. A decrease in blood path width or an increase in intraoxygenator turbulence for instance, might increase gas transfer efficiency but it will increase shear stress as well. The aim of this clinical study was to examine the association between shear stress and oxygen and carbon dioxide transfer in different contemporary oxygenators during cardiopulmonary bypass (CPB). The effect of additional parameters related to gas transfer efficiency, that is, blood flow, gas flow, sweep gas oxygen fraction (FiO2 ), hemoglobin concentration, the amount of hemoglobin pumped through the oxygenator per minute-Qhb, and shunt fraction were contemplated as well. Data from 50 adult patients who underwent elective CPB for coronary artery bypass grafting or aortic valve replacement were retrospectively analyzed. Data included five different oxygenator types with an integrated arterial filter. Relationships were determined using Pearson bivariate correlation analysis and scatterplots with LOESS curves. In the Capiox FX25, Fusion, Inspire 8F, Paragon, and Quadrox-i groups, mean blood flows were 4.8 +/- 0.9, 5.3 +/- 0.7, 4.9 +/- 0.7, 5.0 +/- 0.6, and 5.7 +/- 0.6 L/min, respectively. The mean O2 transfer/m2 membrane surface area was 44 +/- 14, 51 +/- 9, 60 +/- 10, 63 +/- 14, and 77 +/- 18, respectively, whereas the mean CO2 transfer/m2 was 26 +/- 14, 60 +/- 22, 73 +/- 29, 74 +/- 19, and 96 +/- 20, respectively. Associations between oxygen transfer/m2 and shear stress differed per oxygenator, depending on oxygenator design and the level of shear stress (r = 0.249, r = 0.562, r = 0.402, r = 0.465, and r = 0.275 for Capiox FX25, Fusion, Inspire 8F, Paragon, and Quadrox-i, respectively, P < 0.001 for all). Similar associations were noted between CO2 transfer/m2 and shear stress (r = 0.303, r = 0.439, r = 0.540, r = 0.392, and r = 0.538 for Capiox FX25, Fusion, Inspire 8F, Paragon, and Quadrox-i, respectively, P < 0.001 for all). In addition, O2 transfer/m2 was strongly correlated with FiO2 (r = 0.633, P < 0.001), blood flow (r = 0.529, P < 0.001), and Qhb (r = 0.589, P < 0.001). CO2 transfer/m2 in contrast was predominately correlated to sweep gas flow (r = 0.567, P < 0.001). The design-dependent relationship between shear stress and gas transfer revealed that every oxygenator has an optimal range of blood flow and thus shear stress at which gas transfer is most efficient. Gas transfer is further affected by factors influencing the O2 or CO2 concentration gradient between the blood and the gas compartment.

AB - Studies that have investigated circadian, weekday and seasonal variation in postoperative mortality have been relatively small or have been for scheduled surgery. We retrospectively tested a large mixed surgical cohort from a German tertiary care university hospital for the presence of cyclical variation in all cause in-hospital mortality after operations performed between 2006 and 2013. We analysed mortality rates after 247,475 operations, adjusted for age, sex, comorbidities, location, urgency and duration of the surgery, and intra-operative blood transfusions. The mortality odds ratio (95%CI) after operations started in the morning (08:00-11:00) were lowest, 0.73 (0.66-0.80), p < 0.001 and highest for operations started in the afternoon (13:00-17:00), 1.29 (1.18-1.40), p < 0.001. Mortality at the weekend was the same as during the week. There was no seasonal variation in mortality, p = 0.12. However, the interference of four yearly and ten-monthly cycle amplitudes resulted in higher mortality odds ratio (95%CI) in winter 2008-2009, 1.41 (1.18-1.69), p < 0.001, and lower mortality in spring 2011 and 2012, 0.70 (0.56-0.85) and 0.67 (0.53-0.85), p < 0.001 and p = 0.001, respectively. The ability to predict cyclical phenomena would facilitate the design of interventional studies, aimed at reducing mortality following surgery in the afternoon and when cycles interfere constructively.

AB - Immune homeostasis has been suggested to play an important role in the clinical evolution of chronic Chagas disease; however, the immunopathologic factors involved have not been fully elucidated. Therefore, our study aimed to analyse the frequency of CD4+ CD25+ FoxP3+ cells, classic Th17 cells, alternative Th17 cells and IL-17+ B cells from peripheral blood of chronic cardiac patients after in vitro stimulation with Trypanosoma cruzi soluble EPI antigen. Patients were selected and classified according to clinical evaluation of cardiac involvement: mild, B1 (CARD1) (n = 20) and severe, C (CARD2) (n = 11). Patients with the indeterminate form of CD were included as the control group A (IND) (n = 17). Blood samples were collected and cultured in the presence of EPI antigen. Cells frequency and median fluorescence intensity (MFI) were obtained by flow cytometry. Our results showed that only CD4+ CD25+ FoxP3+ , CD4+ CD25high FoxP3+ , CD4+ IL-17+ IFN-gamma- and CD4+ IL-17+ IFN-gamma+ cells are more frequent in patients with severe cardiac disease and correlate with worse global cardiac function. However, while indeterminate patients demonstrated a positive correlation between CD4+ CD25+ FoxP3+ and CD4+ IL-17+ IFN-gamma- Th17 cells, this relationship was not observed in cardiac patients. IL-17 expression by Th17 cells and B cells correlated with disease progression. Altogether our results suggest that the clinical progression of Chagas cardiomyopathy involves worsening of inflammation and impairment of immunoregulatory mechanisms.

AB - OBJECTIVE: To summarize evidence regarding the effectiveness of using chlorhexidine for oral healthcare on patients in the intensive care unit for the prevention of nosocomial pneumonia and ventilator-associated pneumonia. METHODS: This overview of systematic reviews was developed using articles found in PUBMED, Cochrane Library, LILACS, CRD, CINHAL, manual search and grey literature. RESULTS: Of the total 16 systematic reviews, 14 included meta-analysis. Most of them were classified with high methodological quality. In seven systematic reviews, chlorhexidine was effective for prevention of nosocomial pneumonia and ventilator-associated pneumonia in adult population in cardiothoracic intensive care unit. The effectiveness was contradictory with other population patients in intensive care units. CONCLUSION: Chlorhexidine has proven to be effective for the prevention of NP among adult populations in cardiothoracic ICU. In ICUs with patients who have varied clinical-surgical conditions, the effectiveness of chlorhexidine for the prevention of PN and VAP was inconclusive.

AB - The synthesis and optical properties of 1,8-diphenyl-9,10 bis(arylethynyl)phenanthrenes, which are distorted phenanthrenes, are reported. The presence of the two phenyl groups at the 1,8-positions of phenanthrene significantly distorts the molecular geometries, as was evidenced by X-ray crystallography. The congested substitution pattern in the K region results in a distorted aromatic framework, which leads to a redshift in the emission spectrum. These observations are in stark contrast to 9,10-bis(phenylethynyl)phenanthrene with no phenyl groups at the 1,8-positions. A large Stokes shift suggested extensive structural relaxation between the phenyl and arylethynyl units in the excited state, which was supported by theoretical calculations.

AB - BACKGROUND: People with Parkinson's disease (PD) who develop visuo-perceptual deficits are at higher risk of dementia, but we lack tests that detect subtle visuo-perceptual deficits and can be performed by untrained personnel. Hallucinations are associated with cognitive impairment and typically involve perception of complex objects. Changes in object perception may therefore be a sensitive marker of visuo-perceptual deficits in PD. OBJECTIVE: We developed an online platform to test visuo-perceptual function. We hypothesised that (1) visuo perceptual deficits in PD could be detected using online tests, (2) object perception would be preferentially affected, and (3) these deficits would be caused by changes in perception rather than response bias. METHODS: We assessed 91 people with PD and 275 controls. Performance was compared using classical frequentist statistics. We then fitted a hierarchical Bayesian signal detection theory model to a subset of tasks. RESULTS: People with PD were worse than controls at object recognition, showing no deficits in other visuo-perceptual tests. Specifically, they were worse at identifying skewed images (P < .0001); at detecting hidden objects (P = .0039); at identifying objects in peripheral vision (P < .0001); and at detecting biological motion (P = .0065). In contrast, people with PD were not worse at mental rotation or subjective size perception. Using signal detection modelling, we found this effect was driven by change in perceptual sensitivity rather than response bias. CONCLUSIONS: Online tests can detect visuo-perceptual deficits in people with PD, with object recognition particularly affected. Ultimately, visuo-perceptual tests may be developed to identify at-risk patients for clinical trials to slow PD dementia. (c) 2018 The Authors.

AB - Absolute (i.e. measured) rhinal and hippocampal phase values are predictive for memory formation. It has been an open question, whether the capability of mediotemporal structures to react to stimulus presentation with phase shifts may be similarly indicative of successful memory formation. We analysed data from 27 epilepsy patients implanted with depth electrodes in the hippocampus and entorhinal cortex, who performed a continuous word recognition task. Electroencephalographic phase information related to the first presentation of repeatedly presented words was used for prediction of subsequent remembering vs. forgetting applying a support vector machine. The capability to predict successful memory formation based on stimulus-related phase shifts was compared to that based on absolute phase values. Average hippocampal phase shifts were larger and rhinal phase shifts were more accumulated for later remembered compared to forgotten trials. Nevertheless, prediction based on absolute phase values clearly outperformed phase shifts and there was no significant increase in prediction accuracies when combining both measures. Our findings indicate that absolute rhinal and hippocampal phases and not stimulus-related phase shifts are most relevant for successful memory formation. Absolute phases possibly affect memory formation via influencing neural membrane potentials and thereby controlling the timing of neural firing.

AB - Histopathology index systems involve the application of weighted scores to various diagnostic findings for the purpose of calculating overall organ and/or whole-animal health measurements. Such systems were originally developed as tools for monitoring the general health of fish populations. More recently, index systems have been applied to hypothesis-based toxicological studies, the goal of which is to investigate whether a cause-and-effect relationship exists between exposure to a particular test substance or environmental contaminant and morphologic effects in fish tissues. However, the application of index systems in that context is problematic for various reasons: a dependency on untested assumptions of toxicological importance for different types of histopathologic findings; organ scores that combine mechanistically unrelated and potentially contradictory diagnoses; calculations that include excessive numbers of findings, some of which may be incidental to the study outcome; failure to incorporate additional relevant results into the data interpretation, such as clinical observations, macroscopic findings, organ/body weights, clinical pathology data, and the results of hormonal or other biochemical assays; the inappropriate mathematical manipulation of ordinal categorical data (e.g., severity scores and "importance factors"); and a tendency of these systems to amplify, mask, and divert attention from methodological weaknesses and inaccurate diagnoses. The purpose of the present article is to demonstrate why the use of index systems is a misguided approach for handling histopathology data in studies of potential fish toxicants.

AB - The use of engineered nanomaterials (ENM) has grown after the turn of the 21st century. Also, the production of ENM has globally grown, and exposure of workers especially via the lungs to ENM has increased. This review tackles with effects of ENM on workers' health because occupational environment is the main source of exposure to ENM. Assessment of exposure to ENM is demanding, and today there are no occupational exposure level (OEL) for ENM. This is partly due to challenges of such measurements, and in part to the unknown causality between ENM metrics and effects. There are also marked gaps in systematic knowledge on ENM hazards. Human health surveys of exposed workers, or human field studies have not identified specific effects of ENM linking them with a specific exposure. There is, however, a consensus that material characteristics such as size, and chemistry influence effects of ENM. Available data suggest that multiwalled carbon nanotubes (MWCNT) affect the immunological system and cause inflammation of the lungs, or signs of asthma whereas carbon nanofibers (CNF) may cause interstitial fibrosis. Metallic and metal oxide nanoparticles together with MWCNT induce genotoxicity, and a given type of MWCNT has been identified as a possible human carcinogen. Currently, lack of understanding of mechanisms of effects of ENM renders assessment of hazards and risks of ENM material-by-material a necessity. The so called "omics" approaches utilizing ENM-induced alterations in gene and protein expression may be useful in the development of a new paradigm for ENM hazard and risk assessment.

AB - BACKGROUND: Cancer screening-related decisions require patients to evaluate complex medical information in short time frames, often with primary care providers (PCPs) they do not know. PCPs play an essential role in facilitating comprehensive shared decision making (SDM). OBJECTIVE: To develop and test a decision aid (DA) and SDM strategy for PCPs and high-risk patients. DESIGN: The DA was tested with 20 dyads. Each dyad consisted of one PCP and one patient eligible for screening. A prospective, one-group, mixed-method study design measured fidelity, patient values, screening intention, acceptability and satisfaction. RESULTS: Four PCPs and 20 patients were recruited from an urban academic medical centre. Most patients were female (n = 14, 70%), most had completed high school (n = 15, 75%), and their average age was 65 years old. Half were African American. Patients and PCPs rated the DA as helpful, easy to read and use and acceptable in terms of time frame (observed t = 11.6 minutes, SD 2.7). Most patients (n = 16, 80%) indicated their intent to be screened. PCPs recommended screening for most patients (n = 17, 85%). CONCLUSIONS: Evidence supports the value of lung cancer screening with LDCT for select high-risk patients. Guidelines endorse engaging patients and their PCPs in SDM discussions. Our findings suggest that using a brief, interactive, plain-language, culturally sensitive, theory-based DA and SDM strategy is feasible, acceptable and may be essential to effectively translate and sustain the adoption of LDCT screening recommendations into the clinic setting. PMID- 29473697 TI - Distinct clusters of stunted children in India: An observational study. AB - Childhood stunting is often conceptualised as a singular concept (i.e., stunted or not), and such an approach implies similarity in the experiences of children who are stunted. Furthermore, risk factors for stunting are often treated in isolation, and limited research has examined how multiple risk factors interact together. Our aim was to examine whether there are subgroups among stunted children, and if parental characteristics influence the likelihood of these subgroups among children. Children who were stunted were identified from the 2005 2006 Indian National Family Health Survey (n = 12,417). Latent class analysis was used to explore the existence of subgroups among stunted children by their social, demographic, and health characteristics. We examined whether parental characteristics predicted the likelihood of a child belonging to each latent class using a multinomial logit regression model. We found there to be 5 distinct groups of stunted children; "poor, older, and poor health-related outcomes," "poor, young, and poorest health-related outcomes," "poor with mixed health related outcomes," "wealthy and good health-related outcomes," and "typical traits." Both mother and father's educational attainment, body mass index, and height were important predictors of class membership. Our findings demonstrate evidence that there is heterogeneity of the risk factors and behaviours among children who are stunted. It suggests that stunting is not a singular concept; rather, there are multiple experiences represented by our "types" of stunting. Adopting a multidimensional approach to conceptualising stunting may be important for improving the design and targeting of interventions for managing stunting.

AB - OBJECTIVE: Depression is a prevalent and costly mental health problem that affects women as well as their larger communities, with substantial impacts on mother and infant during childbearing years. Face-to-face care has not adequately addressed this global concern due to difficulties in scaling these resources. Internet interventions, which can provide psychological tools to those lacking adequate access, show promise in filling this void. METHOD: We conducted a 2 condition proof-of-concept pilot randomized trial comparing brief Internet-based cognitive behavioural therapy (CBT) and brief Internet-based compassionate mind training (CMT) for women who are currently pregnant, became pregnant within the last year, and intend to become pregnant in the future. RESULTS: We found that, although CMT and CBT demonstrated near equivalence in improving affect, self reassurance, self-criticism, and self-compassion, CMT showed superiority to CBT in reducing depression and anxiety symptoms. CONCLUSION: These findings provide a compelling initial argument for the use of CMT as an avenue for addressing problems associated with negative affect. Implications, limitations, and future directions along this line of research will also be discussed. PMID- 29473699 TI - Evaluation of chalcones as inhibitors of glutathione S-transferase. AB - Glutathione S-transferases (GSTs) are the superfamily of multifunctional detoxification isoenzymes and play an important role in cellular signaling. In the present study, potential inhibition effects of chalcones were tested against human GST. For this purpose, GST was purified from human erythrocytes with 5.381 EU?mg-1 specific activity and 51.95% yield using a GSH-agarose affinity chromatographic method. The effects of chalcones on in vitro GST activity were tested at various concentrations. Ki constants of chalcones were found in the range of 7.76-41.93 MUM. According to the results, 4-fluorochalcone showed a better inhibitory effect compared with the other compounds. The inhibition mechanisms of 2'-hydroxy-4-methoxychalcone and 4-methoxychalcone were noncompetitive, whereas the inhibition mechanisms of 4'- hydroxychalcone, 4- fluorochalcone, and 4,4'- diflurochalcone were competitive. PMID- 29473700 TI - Indirect vs direct assessment of gastric emptying: A randomized crossover trial comparing C-isotope breath analysis and MRI. AB - BACKGROUND: Indirect methods to assess gastric emptying (GE), such as 13 C breath tests (BT), are commonly used. However, BT usually use a sampling time of 4+ hours. The current study aims to assess the validity of BT for four liquid meals differing in physicochemical properties. To this aim, we compared them to MRI GE measurements. METHODS: Fifteen healthy males (age 22.6 +/- 2.4 years, BMI 22.6 +/ 1.8 kg/m2 ) participated in a randomized 2 * 2 crossover experiment. Test foods were liquid meals, which were either thin/thick and 100/500 kcal, labeled with 100 mg of 13 C-octanoate. GE was measured with MRI and assessed by 13 C recovery from breath. Participants were scanned every 10 minutes and at six time points breath samples were collected up to t = 90 minutes. Two curves were fitted to the data to estimate emptying halftime (t50 Ghoos and t50 Bluck ). T50 times were ranked per participant and compared between methods. KEY RESULTS: On average, MRI and BT showed similar t50 rankings for the four liquid meals. In comparison to MRI, t50 Ghoos overestimated, while t50 Bluck underestimated GE time. Moreover, more viscous foods were overestimated. In most participants individual t50 time rankings differed significantly between methods. CONCLUSIONS & INFERENCES: BT can assess relative emptying differences on group level and collecting breath data for 90 minutes constitutes a lower burden for participants and the research facility. However, BT has severe shortcomings compared to MRI for individual GE assessment. Notably, food matrix effects should be considered when interpreting the results of BT. PMID- 29473701 TI - Antibody Epitope of Human alpha-Galactosidase A Revealed by Affinity Mass Spectrometry: A Basis for Reversing Immunoreactivity in Enzyme Replacement Therapy of Fabry Disease. AB - alpha-Galactosidase (alphaGal) is a lysosomal enzyme that hydrolyses the terminal alpha-galactosyl moiety from glycosphingolipids. Mutations in the encoding genes for alphaGal lead to defective or misfolded enzyme, which results in substrate accumulation and subsequent organ dysfunction. The metabolic disease caused by a deficiency of human alpha-galactosidase A is known as Fabry disease or Fabry Anderson disease, and it belongs to a larger group known as lysosomal storage diseases. An effective treatment for Fabry disease has been developed by enzyme replacement therapy (ERT), which involves infusions of purified recombinant enzyme in order to increase enzyme levels and decrease the amounts of accumulated substrate. However, immunoreactivity and IgG antibody formation are major, therapy-limiting, and eventually life-threatening complications of ERT. The present study focused on the epitope determination of human alpha-galactosidase A against its antibody formed. Here we report the identification of the epitope of human alphaGal(309-332) recognized by a human monoclonal anti-alphaGal antibody, using a combination of proteolytic excision of the immobilized immune complex and surface plasmon resonance biosensing mass spectrometry. The epitope peptide, alphaGal(309-332), was synthesized by solid-phase peptide synthesis. Determination of its affinity by surface plasmon resonance analysis revealed a high binding affinity for the antibody (KD =39*10-9 m), which is nearly identical to that of the full-length enzyme (KD =16*10-9 m). The proteolytic excision affinity mass spectrometry method is shown here to be an efficient tool for epitope identification of an immunogenic lysosomal enzyme. Because the full length alphaGal and the antibody epitope showed similar binding affinities, this provides a basis for reversing immunogenicity upon ERT by: 1) treatment of patients with the epitope peptide to neutralize antibodies, or 2) removal of antibodies by apheresis, and thus significantly improving the response to ERT.

AB - Herein we describe a mild method for the dual C(sp3 )-H bond functionalization of saturated nitrogen-containing heterocycles through a sequential visible-light photocatalyzed dehydrogenation/[2+2] cycloaddition procedure. As a complementary approach to the well-established use of iminium ion and alpha-amino radical intermediates, the elusive cyclic enamine intermediates were effectively generated by photoredox catalysis under mild conditions and efficiently captured by acetylene esters to form a wide array of bicyclic amino acid derivatives, thus enabling the simultaneous functionalization of two vicinal C(sp3 )-H bonds. PMID- 29473703 TI - Application of case mix index in the allocation of nursing human resources. AB - AIM: To investigate the feasibility of the case mix index and compare the allocation of nursing human resources between two departments of a hospital with different case mix indexes in China. BACKGROUND: The case mix index is used to assess the resource allocation of all cases in two departments of a hospital. Its values can determine the resource allocation required to diagnose and treat the patients. METHODS: Clinical data were obtained from 23 different departments in 2015 and analysed retrospectively from October to November, 2016. Factors influencing the allocation of registered nurses were identified, and balanced quantities of patients with different case mix indexes were chosen from two departments. Spearman correlation analysis was performed. RESULTS: The per capita nursing workload was significant (r = .669, p = .000). The length of hospital stay, quantity of nurses, and department case mix index were correlated with the nursing workload (t = 4.211, p = .000; t = 2.962, p = .008; t = 2.266, p = .035). Education levels (Z = -1.391, p = .164) and the professional titles (Z = -1.832, p = .067) of the nurses were not statistically significant, whereas the registered nurse level differed between two departments (Z = -2.125, p = .034). CONCLUSION: The case management index provides references for the efficient allocation of registered nurses in clinical practice. PMID- 29473704 TI - Effect of exenatide QW or placebo, both added to titrated insulin glargine, in uncontrolled type 2 diabetes: The DURATION-7 randomized study. AB - AIMS: To compare the efficacy and safety of adding the glucagon-like peptide-1 receptor agonist exenatide once weekly (QW) 2 mg or placebo among patients with type 2 diabetes who were inadequately controlled despite titrated insulin glargine (IG) +/- metformin. METHODS: This multicentre, double-blind study (ClinicalTrials.gov identifier: NCT02229383) randomized (1:1) patients with persistent hyperglycaemia after an 8-week titration phase (glycated haemoglobin [HbA1c] 7.0%-10.5% [53-91 mmol/mol]) to exenatide QW or placebo. The primary endpoint was HbA1c change from baseline to week 28. Secondary endpoints included body weight, 2-hour postprandial glucose, and mean daily IG dose. RESULTS: Of 464 randomized patients (mean: age, 58 years; HbA1c, 8.5% [69 mmol/mol]; diabetes duration, 11.3 years), 91% completed 28 weeks. Exenatide QW + IG vs placebo + IG significantly reduced HbA1c (least-squares mean difference, -0.73% [-8.0 mmol/mol]; 95% confidence interval, -0.93%, -0.53% [-10.2, -5.8 mmol/mol]; P < .001; final HbA1c, 7.55% [59 mmol/mol] and 8.24% [67 mmol/mol], respectively); body weight (-1.50 kg; -2.17, -0.84; P < .001); and 2-hour postprandial glucose ( 1.52 mmol/L [-27.5 mg/dL]; -2.15, -0.90 [-38.7, -16.2]; P < .001). Significantly more exenatide QW + IG-treated patients vs placebo + IG-treated patients reached HbA1c <7.0% (<53 mmol/mol) (32.5% vs 7.4%; P < .001); daily IG dose increased by 2 and 4 units, respectively. Gastrointestinal and injection-site adverse events were more frequent with exenatide QW + IG (15.1% and 7.8%, respectively) than with placebo + IG (10.8% and 3.0%, respectively); hypoglycaemia incidence was similar between the exenatide QW + IG (29.7%) and placebo + IG (29.0%) groups, with no major hypoglycaemic events. CONCLUSIONS: Among patients with inadequate glycaemic control, exenatide QW significantly improved glucose control and decreased body weight, without increased hypoglycaemia or unexpected safety findings. PMID- 29473706 TI - The influence of need for cognitive closure on the attention-recognition stage of preventive coping. AB - The current study explored the influence of need for cognitive closure (NFCC) on preventive coping via its effects on the attention-recognition stage and sought to determine whether this influence was moderated by individuals' existing knowledge. An experiment involving 90 university students used the vignette reading paradigm to explore the relationships between NFCC, attention and preventive coping behaviour. The results indicated that when preventive coping situations were consistent with participants' previous knowledge, people with high, relative to low, NFCC were more inclined to use preventive coping strategies. As a stage of preventive coping, gaining awareness of potential stressors mediated the relationship between NFCC and preventive coping. However, when coping situations were inconsistent with participants' knowledge, the relationship between NFCC and preventive coping was non-significant. PMID- 29473705 TI - Alpha-1 antitrypsin treatment of new-onset type 1 diabetes: An open-label, phase I clinical trial (RETAIN) to assess safety and pharmacokinetics. AB - OBJECTIVE: To determine the safety and pharmacokinetics of alpha-1 antitrypsin (AAT) in adults and children. RESEARCH DESIGN AND METHODS: Short-term AAT treatment restores euglycemia in the non-obese mouse model of type 1 diabetes. A phase I multicenter study in 16 subjects with new-onset type 1 diabetes studied the safety and pharmacokinetics of Aralast NP (AAT). This open-label, dose escalation study enrolled 8 adults aged 16 to 35 years and 8 children aged 8 to 15 years within 100 days of diagnosis, to receive 12 infusions of AAT: a low dose of 45 mg/kg weekly for 6 weeks, followed by a higher dose of 90 mg/kg for 6 weeks. RESULTS: C-peptide secretion during a mixed meal, hemoglobin A1c (HbA1c), and insulin usage remained relatively stable during the treatment period. At 72 hours after infusion of 90 mg/kg, mean levels of AAT fell below 2.0 g/L for 7 of 15 subjects. To identify a plasma level of AAT likely to be therapeutic, pharmacodynamic ex vivo assays were performed on fresh whole blood from adult subjects. Polymerase chain reaction (PCR) analyses were performed on inhibitor of IKBKE, NOD1, TLR1, and TRAD gene expression, which are important for activation of nuclear factor-kappaB (NF-kappaB) and apoptosis pathways. AAT suppressed expression dose-dependently; 50% inhibition was achieved in the 2.5 to 5.0 mg/mL range. CONCLUSIONS: AAT was well tolerated and safe in subjects with new-onset type 1 diabetes. Weekly doses of AAT greater than 90 mg/kg may be necessary for an optimal therapeutic effect. PMID- 29473709 TI - Efficacy and safety of canagliflozin as add-on therapy to a glucagon-like peptide 1 receptor agonist in Japanese patients with type 2 diabetes mellitus: A 52-week, open-label, phase IV study. AB - Sodium-glucose co-transporter-2 (SGLT2) inhibitors and glucagon-like peptide-1 receptor agonists (GLP-1RAs) are antihyperglycaemic agents with weight-lowering effects. The efficacy and safety of the SGLT2 inhibitor canagliflozin as add-on therapy in Japanese patients with type 2 diabetes mellitus (T2DM) and inadequate glycaemic control with a GLP-1RA (>=12 weeks) were evaluated in this phase IV study. Patients received canagliflozin 100 mg once daily for 52 weeks. Efficacy endpoints included change in glycated haemoglobin (HbA1c), fasting plasma glucose (FPG), body weight, systolic blood pressure (SBP) and HDL cholesterol from baseline to week 52. Safety endpoints included adverse events (AEs), hypoglycaemia and laboratory tests. Of the 71 patients treated with canagliflozin, 63 completed the study. At 52 weeks, HbA1c was significantly reduced from baseline (-0.70%; paired t test, P < .001). Significant changes were also observed in FPG (-34.7 mg/dL), body weight (-4.46%), SBP (-7.90 mm Hg), and HDL cholesterol (7.60%; all P < .001). The incidence of AEs, adverse drug reactions and hypoglycaemia was 71.8%, 32.4% and 9.9%, respectively. All hypoglycaemic events were mild. These findings suggest that the long-term combination of canagliflozin with a GLP-1RA is effective and well tolerated in Japanese patients with T2DM.

AB - H3K4me3 plays important roles in development, transcription, and environmental responses. Here, we report that SDG721 (SET-domain group protein 721) and SDG705 are involved in regulating rice development. SDG721 and SDG705 encode TRITHORAX like proteins, which appear to modulate H3K4 methylation levels. Loss of SDG721 and SDG705 function resulted in GA-deficient phenotypes, including semi-dwarfism, reduced cell length, and reduced panicle branching. The transcripts levels and H3K4me3 levels of GA biosynthesis genes and GA signaling pathway genes were downregulated in the sdg721 sdg705 plants. Together, these results suggest that SDG721 and SDG705 regulate H3K4 methylation, which is crucial for plant development in rice.

AB - Millions of barrels of oil were released into the Gulf of Mexico following the 2010 explosion of the Deepwater Horizon oil rig. Polycyclic aromatic hydrocarbons (PAHs) are toxic components of crude oil, which may become more toxic in the presence of ultraviolet (UV) radiation, a phenomenon known as photo-induced toxicity. The Deepwater Horizon spill impacted offshore and estuarine sites, where biota may be co-exposed to UV and PAHs. Penetration of UV into the water column is affected by site-specific factors. Therefore, measurements and/or estimations of UV are necessary when one is assessing the risk to biota posed by photo-induced toxicity. We describe how estimates of incident UV were determined for the area impacted by the Deepwater Horizon oil spill, using monitoring data from radiometers near the spill, in conjunction with reference spectra characterizing the composition of solar radiation. Furthermore, we provide UV attenuation coefficients for both near- and offshore sites in the Gulf of Mexico. These estimates are specific to the time and location of the spill, and fall within the range of intensities utilized during photo-induced toxicity tests performed in support of the Deepwater Horizon Natural Resource Damage Assessment (NRDA). These data further validate the methodologies and findings of phototoxicity tests included in the Deepwater Horizon NRDA, while underscoring the importance of considering UV exposure when assessing possible risks following oil spills.

AB - Recent research showed that invariant natural killer T (iNKT) cells take part in the regulation of osteoclastogenesis. While the role of iNKT cells in myeloma bone disease (MBD) remains unclear. In our study, the quantity of iNKT cells and the levels of cytokines produced by them were measured by flow cytometry. iNKT cells and osteoclasts were induced from peripheral blood mononuclear cells after activation by alpha-GalCer or RANKL in vitro. Then, gene expressions and the levels of cytokines were determined by RT-PCR and ELISA, respectively. The results showed that the quantity of iNKT and production of IFN-gamma by iNKT cells were significantly decreased in newly diagnosed MM (NDMM), and both negatively related with severity of bone disease. Then, the osteoclasts from healthy controls were cultured in vitro and were found to be down-regulated after alpha-GalCer-stimulated, while there was no significant change with or without alpha-GalCer in NDMM patients, indicating that the regulation of osteoclastogenesis by iNKT cells was impaired. Furthermore, the inhibition of osteoclastogenesis by iNKT cells was regulated by IFN-gamma production, which down-regulated osteoclast-associated genes. In conclusion, the role of alpha GalCer-stimulated iNKT cells in regulation of osteoclastogenesis was impaired in MBD, as a result of iNKT cell dysfunction. PMID- 29473716 TI - Magneto-Mechanical Surfaces Design. AB - Magneto-mechanically active surfaces (MMAS) represent a new family of nano/micro structured surfaces in which motion is induced by an external magnetic field. Under the name of "artificial cilia", "biomimetic cilia", "magnetic actuated patterns", "nanopillars", etc., published works in this area continue their quick growth in number. Notwithstanding their potential application in microfluidic, chemical sensors, catalytic processes and microelectronics to increase device perfomances, there is still a lot to do in the development of these materials. Improvement and optimization of the performance of these structures are essential tasks in order to fulfil their complete development. Along this article, a critical review involving the main aspects in the design of the patterned nanocomposites will be presented. PMID- 29473715 TI - Multinational Qualitative Research Study Exploring the Patient Experience of Raynaud's Phenomenon in Systemic Sclerosis. AB - OBJECTIVE: Raynaud's phenomenon (RP) is the most common manifestation of systemic sclerosis (SSc). RP is an episodic phenomenon, not easily assessed in the clinic, leading to reliance on self-report. A thorough understanding of the patient experience of SSc-RP is essential to ensuring that patient-reported outcome (PRO) instruments capture domains important to the target patient population. We report the findings of an international qualitative research study investigating the patient experience of SSc-RP. METHODS: Focus groups of SSc patients were conducted across 3 scleroderma centers in the US and UK, using a topic guide and a priori purposive sampling framework devised by qualitative researchers, SSc patients, and SSc experts. Focus groups were audio recorded, transcribed, anonymized, and analyzed using inductive thematic analysis. Focus groups were conducted until thematic saturation was achieved. RESULTS: Forty SSc patients participated in 6 focus groups conducted in Bath (UK), New Orleans (Louisiana), and Pittsburgh (Pennsylvania). Seven major themes were identified that encapsulate the patient experience of SSc-RP: physical symptoms, emotional impact, triggers and exacerbating factors, constant vigilance and self management, impact on daily life, uncertainty, and adaptation. The interrelationship of the 7 constituent themes can be arranged within a conceptual map of SSc-RP. CONCLUSION: We have explored the patient experience of SSc-RP in a diverse and representative SSc cohort and identified a complex interplay of experiences that result in significant impact. Work to develop a novel PRO instrument for assessing the severity and impact of SSc-RP, comprising domains/items grounded in the patient experiences of SSc-RP identified in this study, is underway.

PMID- 29473719 TI - Diabetic Macular Edema: Current Understanding, Pharmacologic Treatment Options, and Developing Therapies. AB - Diabetic retinopathy and diabetic macular edema comprise a major source of visual disability throughout the developed world. The etiology and pathogenesis of macular edema is intricate and multifactorial, in which the hyperglycemic state in diabetes induces a microangiopathy. Through several inflammatory and vasogenic mediators, including vascular endothelial growth factor (VEGF) upregulation and inflammatory cytokines and chemokines, pathologic changes are induced in the vascular endothelium triggering breakdown of the blood retinal barrier, causing extravasation of fluid into the extracellular space and manifesting clinically as macular edema, resulting in visual loss. The advent of medications targeting the VEGF pathway has led to great clinical improvements compared with the previous standard of care of laser therapy alone, as shown in studies such as RISE, RIDE, VIVID, VISTA, and DRCR. However, analyses have shown that many patients have inadequate response or are nonresponders to anti-VEGF therapy, demonstrating the need for additional therapies to more comprehensively treat this disease. Although corticosteroid treatments and implants have demonstrated some efficacy in adjunctive and supplemental treatment, the need to more adequately treat macular edema remains. Our knowledge of diabetic macular edema continues to grow, leading to new currently available and emerging pharmacotherapies to further enhance our treatment and restore vision in those affected by diabetic macular edema. This review will discuss the pathogenesis of diabetic macular edema and the pharmacologic therapies available for its treatment, including anti-VEGF, steroids, and newer therapies still in development, such as angiopoietin antagonists, Tie2 agonists, kallikrein inhibitors, interleukin inhibitors, and others. PMID- 29473717 TI - Interventions for paracetamol (acetaminophen) overdose. AB - BACKGROUND: Paracetamol (acetaminophen) is the most widely used non-prescription analgesic in the world. Paracetamol is commonly taken in overdose either deliberately or unintentionally. In high-income countries, paracetamol toxicity is a common cause of acute liver injury. There are various interventions to treat paracetamol poisoning, depending on the clinical status of the person. These interventions include inhibiting the absorption of paracetamol from the gastrointestinal tract (decontamination), removal of paracetamol from the vascular system, and antidotes to prevent the formation of, or to detoxify, metabolites. OBJECTIVES: To assess the benefits and harms of interventions for paracetamol overdosage irrespective of the cause of the overdose. SEARCH METHODS: We searched The Cochrane Hepato-Biliary Group Controlled Trials Register (January 2017), CENTRAL (2016, Issue 11), MEDLINE (1946 to January 2017), Embase (1974 to January 2017), and Science Citation Index Expanded (1900 to January 2017). We also searched the World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov database (US National Institute of Health) for any ongoing or completed trials (January 2017). We examined the reference lists of relevant papers identified by the search and other published reviews. SELECTION CRITERIA: Randomised clinical trials assessing benefits and harms of interventions in people who have ingested a paracetamol overdose. The interventions could have been gastric lavage, ipecacuanha, or activated charcoal, or various extracorporeal treatments, or antidotes. The interventions could have been compared with placebo, no intervention, or to each other in differing regimens. DATA COLLECTION AND ANALYSIS: Two review authors independently extracted data from the included trials. We used fixed-effect and random-effects Peto odds ratios (OR) with 95% confidence intervals (CI) for analysis of the review outcomes. We used the Cochrane 'Risk of bias' tool to assess the risks of bias (i.e. systematic errors leading to overestimation of benefits and underestimation of harms). We used Trial Sequential Analysis to control risks of random errors (i.e. play of chance) and GRADE to assess the quality of the evidence and constructed 'Summary of findings' tables using GRADE software. MAIN RESULTS: We identified 11 randomised clinical trials (of which one acetylcysteine trial was abandoned due to low numbers recruited), assessing several different interventions in 700 participants. The variety of interventions studied included decontamination, extracorporeal measures, and antidotes to detoxify paracetamol's toxic metabolite; which included methionine, cysteamine, dimercaprol, or acetylcysteine. There were no randomised clinical trials of agents that inhibit cytochrome P-450 to decrease the activation of the toxic metabolite N-acetyl-p benzoquinone imine.Of the 11 trials, only two had two common outcomes, and hence, we could only meta-analyse two comparisons. Each of the remaining comparisons included outcome data from one trial only and hence their results are presented as described in the trials. All trial analyses lack power to access efficacy. Furthermore, all the trials were at high risk of bias. Accordingly, the quality of evidence was low or very low for all comparisons. Interventions that prevent absorption, such as gastric lavage, ipecacuanha, or activated charcoal were compared with placebo or no intervention and with each other in one four-armed randomised clinical trial involving 60 participants with an uncertain randomisation procedure and hence very low quality. The trial presented results on lowering plasma paracetamol levels. Activated charcoal seemed to reduce the absorption of paracetamol, but the clinical benefits were unclear. Activated charcoal seemed to have the best risk:benefit ratio among gastric lavage, ipecacuanha, or supportive treatment if given within four hours of ingestion. There seemed to be no difference between gastric lavage and ipecacuanha, but gastric lavage and ipecacuanha seemed more effective than no treatment (very low quality of evidence). Extracorporeal interventions included charcoal haemoperfusion compared with conventional treatment (supportive care including gastric lavage, intravenous fluids, and fresh frozen plasma) in one trial with 16 participants. The mean cumulative amount of paracetamol removed was 1.4 g. One participant from the haemoperfusion group who had ingested 135 g of paracetamol, died. There were no deaths in the conventional treatment group. Accordingly, we found no benefit of charcoal haemoperfusion (very low quality of evidence). Acetylcysteine appeared superior to placebo and had fewer adverse effects when compared with dimercaprol or cysteamine. Acetylcysteine superiority to methionine was unproven. One small trial (low quality evidence) found that acetylcysteine may reduce mortality in people with fulminant hepatic failure (Peto OR 0.29, 95% CI 0.09 to 0.94). The most recent randomised clinical trials studied different acetylcysteine regimens, with the primary outcome being adverse events. It was unclear which acetylcysteine treatment protocol offered the best efficacy, as most trials were underpowered to look at this outcome. One trial showed that a modified 12-hour acetylcysteine regimen with a two-hour acetylcysteine 100 mg/kg bodyweight loading dose was associated with significantly fewer adverse reactions compared with the traditional three-bag 20.25-hour regimen (low quality of evidence). All Trial Sequential Analyses showed lack of sufficient power. Children were not included in the majority of trials. Hence, the evidence pertains only to adults. AUTHORS' CONCLUSIONS: These results highlight the paucity of randomised clinical trials comparing different interventions for paracetamol overdose and their routes of administration and the low or very low level quality of the evidence that is available. Evidence from a single trial found activated charcoal seemed the best choice to reduce absorption of paracetamol. Acetylcysteine should be given to people at risk of toxicity including people presenting with liver failure. Further randomised clinical trials with low risk of bias and adequate number of participants are required to determine which regimen results in the fewest adverse effects with the best efficacy. Current management of paracetamol poisoning worldwide involves the administration of intravenous or oral acetylcysteine which is based mainly on observational studies. Results from these observational studies indicate that treatment with acetylcysteine seems to result in a decrease in morbidity and mortality, However, further evidence from randomised clinical trials comparing different treatments are needed. PMID- 29473720 TI - Maybe it is not a goal that matters: a report from a physical activity intervention in youth. AB - BACKGROUND: Decline in physical activity (PA), specifically in adolescents raises concerns. Setting goals and strategies are often used to increase the level of moderate-to-vigorous physical activity (MVPA), recently introducing also modern technological devices for achieving different goals. The aim of this study was to investigate the effectiveness of two different goal strategies in increasing PA of youth. It was expected that there would be positive relationships between support and goal strategy which would contribute to increase MVPA. Classmate and teacher support scales were used to evaluate support in physical education (PE) classes. Activity trackers were used to count daily steps. METHODS: Data were collected from 65 late adolescents, divided into two groups: "Goal" (group 1) and "Do your best" (group 2) set with different step goals and strategies. Differences between the terms were tested. To compare MVPA levels with the different level of support they received in girls and boys, a two-way ANOVA was used. RESULTS: There was a difference noticed in teacher support between the genders in all the two groups in favor of boys. Boys with low teacher support in group 1 indicated a higher level of MVPA. In group 2 when teacher support was high girls reported the highest level of MVPA. CONCLUSIONS: This study has shown that in terms of MVPA teacher support is more efficient than a goal strategy. The results highlight the importance of perceived teacher support for motivation in PA and pointed at PE teachers as the agents of behavior change, specifically in girls.

AB - Nurses actively killed people in Nazi Europe between 1939 and 1945. The so-called 'science of eugenics' underpinned Nazi ideology, used to further the Nazi racist agenda. Edicts sanctioned selection and medically supervised killing of people, and nurses, principally in mental hospitals, participated in the killing of between 100-300 thousand patients. Erroneously termed 'euthanasia', there were three phases: the initial programme involving children, the T4 adult programme, and 'wild euthanasia'. Unofficial killings also took place before 1939. This paper uses discourse analysis to map and analyse published texts which explore the role of nurses in Nazi Germany. The aim is to identify its characteristics as a body of literature, to note strengths and weaknesses, emphases and silences, and to note aspects that need further exploration. It acknowledges that how these events are to be understood and represented in contemporary discourse constitutes a significant problem for historians of nursing.

AB - In 1949, federal parliamentarians were indignant when asked to ratify the United Nations Convention on the Prevention and Punishment of the Crime of Genocide (hereafter, UNGC). We could not in any way be associated with 'the unthinkable' crime, senior members claimed, because we are 'a moral people' with a 'clean record'. This essay assesses the 'decent' Australian democrats who, as the indelible records show, set out to kill the Aboriginal people they deemed 'vermin' and then later, decided to engage in a eugenicist fantasy to rid Australia of Aborigines by intermarriage or, failing that, forcibly removing their children in large numbers. The colonial frontier killings were justified as 'dispersing kangaroos'. Child removals were done 'in their best interests'. This essay attempts to gain an insight into the mindset of those who did commit 'the unthinkable' crime of genocide: killing, removal of children, and 'causing serious bodily and mental harm'. Subsequent policies infantalised the Aboriginal and Islander population and denied them basic human rights. PMID- 29473724 TI - The Contemporary Significance of the Holocaust for Australian Psychiatry. AB - In this paper we survey briefly the components of the Holocaust directly relevant to the psychiatric profession and identify the main themes of relevance to contemporary psychiatry. The 'euthanasia' program; the persecution of lesbian, gay, bisexual, transgender, and intersex (LGBTI) citizens; and the complex relationship between the psychiatric profession and Nazi state are the main themes to emerge from this survey. We then compare this period with key themes in the history of Australian psychiatry and link these themes to some of the contemporary ethical challenges the profession faces.

AB - Nanoparticle (NP) mediated drug delivery into viscous biomatrices, e.g., mucus and bacterial biofilms, is challenging. Lipid shell-enveloped polymeric NPs (Lipid@NPs), composed of a polymeric NP core coated with a lipid shell, represent a promising alternative to the current delivery systems. Here, we describe the facile methods to prepare Lipid@NPs with high integrity of lipid shells and demonstrate the potential of Lipid@NPs in an effective mucus penetration and interaction with cystic fibrosis-related bacterial biofilms. Lipid shell enveloped polystyrene NPs with high integrity of lipid shells ( cLipid@PSNPs) were prepared by using an electrostatically mediated layer-by-layer approach, where the model polystyrene NPs (PSNPs) were first modified with positively charged poly-l-lysine (PLL) and 1,2-dioleoyl-3-trimethylammonium-propane (DOTAP), followed by subsequent fusion with zwitterionic, PEGylated small unilamellar vesicles (SUVs). The interaction of the PSNPs with SUVs was significantly enhanced by modifying the PSNPs with PLL and DOTAP, which eventually resulted in the formation of cLipid@PSNPs, i.e., Lipid@PLL-PSNPs and Lipid@DOTAP-PSNPs. Improved mucus-penetrating property of cLipid@PSNPs was demonstrated by quartz crystal microbalance with dissipation monitoring measurements. Furthermore, fluorescence resonance energy transfer measurements showed that the interaction of the cLipid@PSNPs with bacterial biofilms was significantly promoted. In conclusion, we prepared cLipid@PSNPs via an electrostatically mediated layer-by layer approach. Our results suggest that the integrity of the lipid envelopes is crucial for enabling the diffusion of Lipid@PSNPs into the mucus layer and promoting the interaction of Lipid@PSNPs with a bacterial biofilm. PMID- 29473726 TI - Defect Sites-Rich Porous Carbon with Pseudocapacitive Behaviors as an Ultrafast and Long-Term Cycling Anode for Sodium-Ion Batteries. AB - Room-temperature sodium-ion batteries have been regarded as promising candidates for grid-scale energy storage due to their low cost and the wide distribution of sodium sources. The main scientific challenge for their practical application is to develop suitable anodes with long-term cycling stability and high rate capacity. Here, novel hierarchical three-dimensional porous carbon materials are synthesized through an in situ template carbonization process. Electrochemical examination demonstrates that carbonization temperature is a key factor that affects Na+-ion-storage performance, owing to the consequent differences in surface area, pore volume, and degree of crystallinity. The sample obtained at 600 degrees C delivers the best sodium-storage performance, including long-term cycling stability (15 000 cycles) and high rate capacity (126 mAh g-1 at 20 A g 1). Pseudocapacitive behavior in the Na+-ion-storage process has been confirmed and studied via cyclic voltammetry. Full cells based on the porous carbon anode and Na3V2(PO4)3-C cathode also deliver good cycling stability (400 cycles). Porous carbon, combining the merits of high energy density and extraordinary pseudocapacitive behavior after cycling stability, can be a promising replacement for battery/supercapacitors hybrid and suggest a design strategy for new energy storage materials. PMID- 29473727 TI - High Capacity and Superior Cyclic Performances of All-Solid-State Lithium Batteries Enabled by a Glass-Ceramics Solo. AB - By using highly Li-ion conductive 78Li2S-22P2S5 glass-ceramic (7822gc) as both the electrolyte and active material in the composite cathode obtained via ball milling the 7822gc with multiple carbons, a kind of monolithic all-solid-state batteries were prepared with a lithium-indium foil as the anode. Such 7822gc based monolithic batteries present stable discharge capacity of 480.3 mA h g-1 at 0.176 mA cm-2 after 60 cycles, which is three times larger than that of the previous work, with the highest capacity obtained so far among all attempts of using sulfide electrolytes as the active materials. High capacity retention of 90.6% and Coulombic efficiency of higher than 99% with high active material loading of 7 mg cm-2 were also obtained. X-ray photoelectron spectroscopy was used to reveal the electrochemical reaction mechanisms in the 7822gc cathode.

AB - Highly ordered hierarchical Pt and PtNi nanowire arrays were prepared using CdS hierarchical nanowire arrays (HNWAs) as sacrificial templates and demonstrated high electrochemical active surface areas. For the resulting Pt HNWAs sample, the peak current for methanol oxidation at +0.74 V was almost 1 order of magnitude higher than that of Pt solid nanowire arrays prepared in a similar manner but without the use of CdS template, and the addition of a Ni cocatalyst effectively enhanced the tolerance against CO poisoning. The results demonstrated that highly ordered Pt and PtNi HNWAs may be exploited as promising anode catalysts in the application of direct methanol fuel cells. PMID- 29473729 TI - Streptomyces wadayamensis MppP is a PLP-Dependent Oxidase, Not an Oxygenase. AB - The PLP-dependent l-arginine hydroxylase/deaminase MppP from Streptomyces wadayamensis (SwMppP) is involved in the biosynthesis of l-enduracididine, a nonproteinogenic amino acid found in several nonribosomally produced peptide antibiotics. SwMppP uses only PLP and molecular oxygen to catalyze a 4-electron oxidation of l-arginine to form a mixture of 2-oxo-4(S)-hydroxy-5 guanidinovaleric acid and 2-oxo-5-guanidinovaleric acid. Steady-state kinetics analysis in the presence and absence of catalase shows that one molecule of peroxide is formed for every molecule of dioxygen consumed in the reaction. Moreover, for each molecule of 2-oxo-4(S)-hydroxy-5-guanidinovaleric acid produced, two molecules of dioxygen are consumed, suggesting that both the 4 hydroxy and 2-keto groups are derived from water. This was confirmed by running the reactions using either [18]O2 or H2[18]O and analyzing the products by ESI MS. Incorporation of [18]O was only observed when the reaction was performed in H2[18]O. Crystal structures of SwMppP with l-arginine, 2-oxo-4(S)-hydroxy-5 guanidinovaleric acid, or 2-oxo-5-guanidinovaleric acid bound were determined at resolutions of 2.2, 1.9. and 1.8 A, respectively. The structural data show that the N-terminal portion of the protein is disordered unless substrate or product is bound in the active site, in which case it forms a well-ordered helix that covers the catalytic center. This observation suggested that the N-terminal helix may have a role in substrate binding and/or catalysis. Our structural and kinetic characterizations of N-terminal variants show that the N-terminus is critical for catalysis. In light of this new information, we have refined our previously proposed mechanism of the SwMppP-catalyzed oxidation of l-arginine. PMID- 29473730 TI - Noncatalytic Endosialidase Enables Surface Capture of Small-Cell Lung Cancer Cells Utilizing Strong Dendrimer-Mediated Enzyme-Glycoprotein Interactions. AB - Enumeration of circulating tumor cells (CTCs) of small-cell lung cancer (SCLC) patients has been shown to predict the disease progress and long-term survival. Most CTC detection methods rely on epithelial surface markers, such as epithelial cell adhesion molecule (EpCAM). However, this marker in SCLC is reported to be often downregulated after a variety of phenotypic changes, which impairs the reliability of EpCAM-based CTC detections. In this regard, the development of an alternative CTC detection method involving different CTC surface markers is in demand. In this study, we evaluated, for the first time to our knowledge, the feasibility of detecting SCLC CTCs using a noncatalytic endosialidase (EndoN Trap, EndoNt). This noncatalytic enzyme was chosen due to its high affinity to polysialic acid (polySia), a cell-surface glycan, that is highly expressed by SCLC tissue. Furthermore, this enzyme-based system was integrated into our dendrimer-mediated CTC capture platform to further enhance the capture efficiency via multivalent binding. We found that the EndoNt-immobilized surfaces could specifically capture polySia-positive SCLC cells and the binding between SCLC cells and EndoNt surfaces was further stabilized by dendrimer-mediated multivalent binding. When compared to the EpCAM-based capture, EndoNt significantly improved the capture efficiency of polySia-positive SCLC cells under flow due to its higher binding affinity (lower dissociation rate constants). These findings suggest that this enzyme-based CTC capture strategy has the potential to be used as a superior alternative to the commonly used EpCAM based methods, particularly for those types of cancer that overexpress polySia. PMID- 29473731 TI - In Silico Identification and Experimental Validation of Novel Anti-Alzheimer's Multitargeted Ligands from a Marine Source Featuring a "2-Aminoimidazole plus Aromatic Group" Scaffold. AB - Multitargeting or polypharmacological approaches, looking for single chemical entities retaining the ability to bind two or more molecular targets, are a potentially powerful strategy to fight complex, multifactorial pathologies. Unfortunately, the search for multiligand agents is challenging because only a small subset of molecules contained in molecular databases are bioactive and even fewer are active on a preselected set of multiple targets. However, collections of natural compounds feature a significantly higher fraction of bioactive molecules than synthetic ones. In this view, we searched our library of 1175 natural compounds from marine sources for molecules including a 2 aminoimidazole+aromatic group motif, found in known compounds active on single relevant targets for Alzheimer's disease (AD). This identified two molecules, a pseudozoanthoxanthin (1) and a bromo-pyrrole alkaloid (2), which were predicted by a computational approach to possess interesting multitarget profiles on AD target proteins. Biochemical assays experimentally confirmed their biological activities. The two compounds inhibit acetylcholinesterase, butyrylcholinesterase, and beta-secretase enzymes in high- to sub-micromolar range. They are also able to prevent and revert beta-amyloid (Abeta) aggregation of both Abeta1-40 and Abeta1-42 peptides, with 1 being more active than 2. Preliminary in vivo studies suggest that compound 1 is able to restore cholinergic cortico-hippocampal functional connectivity. PMID- 29473732 TI - Innovative Cryopreservation Process Using a Modified Core/Shell Cell-Printing with a Microfluidic System for Cell-Laden Scaffolds. AB - This work investigated the printability and applicability of a core/shell cell printed scaffold for medium-term (for up to 20 days) cryopreservation and subsequent cultivation with acceptable cellular activities including cell viability. We developed an innovative cell-printing process supplemented with a microfluidic channel, a core/shell nozzle, and a low-temperature working stage to obtain a cell-laden 3D porous collagen scaffold for cryopreservation. The 3D porous biomedical scaffold consisted of core/shell struts with a cell-laden collagen-based bioink/dimethyl sulfoxide mixture in the core region and an alginate/poly(ethylene oxide) mixture in the shell region. Following 2 weeks of cryopreservation, the cells (osteoblast-like cells or human adipose stem cells) in the scaffold showed good viability (over 90%), steady growth, and mineralization similar to those of a control scaffold fabricated using a conventional cell-printing process without cryopreservation. We believe that these results are attributable to the optimized fabrication processes the cells underwent, including safe freezing/thawing processes. On the basis of these results, this fabrication process has great potential for obtaining core/shell cell-laden collagen scaffolds for cryopreservation, which have various tissue engineering applications. PMID- 29473733 TI - alpha-l-Threose Nucleic Acids as Biocompatible Antisense Oligonucleotides for Suppressing Gene Expression in Living Cells. AB - Because of the chemical simplicity of alpha-l-threose nucleic acid (TNA) and its ability to exchange genetic information between itself and RNA, it has attracted significant interest as the RNA ancestor. We herein explore the biological properties and evaluate the potency of sequence-designed TNA polymers to suppress the gene expression in living environments. We found that sequence-specific TNA macromolecules exhibit strong affinity and specificity toward the complementary RNA targets, are highly biocompatible and nontoxic in a living cell system, and readily enter a number of cell lines without using transfecting agents. Particularly, TNA exhibited much stronger enzymatic resistance toward fetal bovine serum or human serum as compared to traditional antisense oligonucleotides, which means that the intrinsic structure of TNA is thoroughly resistant to biological degradation. Importantly, the efficacy of the TNA molecule with green fluorescent protein (GFP) target sequence (anti-GFP TNAs) as antisense agents was first demonstrated in living cells in which these polymers revealed high antisense activity in terms of the degree of inhibition of GFP gene expression. The GFP gene inhibition studies in HeLa and HEK293 cells characterize sequence-controlled TNA as a functional biomaterial and a valuable alternative to traditional antisense oligonucleotides such as peptide nucleic acids, phosphorodiamidate morpholino oligomers, and locked nucleic acids for a wide range of applications in drug discovery and life science research. Additionally, we also first reported the cost-efficient approach to synthesize the four TNA phosphoramidite monomers using 2-cyanoethyl N, N, N', N' tetraisopropylphosphoramidite as a key reagent. Furthermore, by increasing the frequency of the deblocking and coupling reactions together with extending their reaction time in each synthesis cycle, sequence-controlled TNAs can be easily synthesized in a quantitative yield and high purity. PMID- 29473734 TI - Ligand Size and Conformation Affect the Behavior of Nanoparticles Coated with in Vitro and in Vivo Protein Corona. AB - Protein corona is immediately established on the surface of nanoparticles upon their introduction into biological milieu. Several studies have shown that the targeting efficiency of ligand-modified nanoparticles is attenuated or abolished owing to the protein adsorption. Here, transferrin receptor-targeting ligands, including LT7 (CHAIYPRH), DT7 (hrpyiahc, all d-form amino acids), and transferrin, were used to identify the influence of the ligand size and conformation on protein corona formation. The results showed that the targeting capacity of ligand-modified nanoparticles was lost after incubation with plasma in vitro, whereas it was partially retained after in vivo corona formation. Results from sodium dodecyl sulfate polyacrylamide gel electrophoresis and liquid chromatography-mass spectrometry revealed the difference in the composition of in vitro and in vivo corona, wherein the ligand size and conformation played a critical role. Differences were observed in cellular internalization and exocytosis profiles on the basis of the ligand and corona source. PMID- 29473735 TI - The Use of Ex Vivo Organ Cultures in Tick-Borne Virus Research. AB - Each year there are more than 15 000 cases of human disease caused by infections with tick-borne viruses (TBVs). These illnesses occur worldwide and can range from very mild illness to severe encephalitis and hemorrhagic fever. Although TBVs are currently identified as neglected vector-borne pathogens and receive less attention than mosquito-borne viruses, TBVs are expanding into new regions, and infection rates are increasing. Furthermore, effective vaccines, diagnostic tools, and other countermeasures are limited. The application of contemporary technologies to TBV infections presents an excellent opportunity to develop improved, effective countermeasures. Experimental tick and mammal models of infection can be used to characterize determinants of infection, transmission, and virulence and to test candidate countermeasures. The use of ex vivo tick cultures in TBV research provides a unique way to look at infection in specific tick organs. Mammal ex vivo organ slice and, more recently, organoid cultures are additional models that can be used to elucidate direct tissue-specific responses to infection. These ex vivo model systems are convenient for testing methods involving transcript knockdown and small molecules under tightly controlled conditions. They can also be combined with in vitro and in vivo studies to tease out possible host factors and potential vaccine or therapeutic candidates. In this brief perspective, we describe how ex vivo cultures can be combined with modern technologies to advance research on TBV infections. PMID- 29473736 TI - Improving the Photo-Oxidative Performance of Bi2MoO6 by Harnessing the Synergy between Spatial Charge Separation and Rational Co-Catalyst Deposition. AB - It has been reported that photogenerated electrons and holes can be directed toward specific crystal facets of a semiconductor particle, which is believed to arise from the differences in their surface electronic structures, suggesting that different facets can act as either photoreduction or photo-oxidation sites. This study examines the propensity for this effect to occur in faceted, plate like bismuth molybdate (Bi2MoO6), which is a useful photocatalyst for water oxidation. Photoexcited electrons and holes are shown to be spatially separated toward the {100} and {001}/{010} facets of Bi2MoO6, respectively, by facet dependent photodeposition of noble metals (Pt, Au, and Ag) and metal oxides (PbO2, MnO x, and CoO x). Theoretical calculations revealed that differences in energy levels between the conduction bands and valence bands of the {100} and {001}/{010} facets can contribute to electrons and holes being drawn to different surfaces of the plate-like Bi2MoO6. Utilizing this knowledge, the photo-oxidative capability of Bi2MoO6 was improved by adding an efficient water oxidation co catalyst, CoO x, to the system, whereby the extent of enhancement was shown to be governed by the co-catalyst location. A greater oxygen evolution occurred when CoO x was selectively deposited on the hole-rich {001}/{010} facets of Bi2MoO6 compared to when CoO x was randomly located across all of the facets. The elevated performance exhibited for the selectively loaded CoO x/Bi2MoO6 was ascribed to the greater opportunity for hole trapping by the co-catalyst being accentuated over other potentially detrimental effects, such as the co-catalyst acting as a recombination medium and/or covering reactive sites. The results indicate that harnessing the synergy between the spatial charge separation and the co-catalyst location on the appropriate facets of plate-like Bi2MoO6 can promote its photocatalytic activity. PMID- 29473737 TI - Optofluidic Sensor for Inline Hemolysis Detection on Whole Blood. AB - Hemolysis is the rupture of red blood cells and constitutes the most common reason for unsuitable blood samples in the clinic. To detect hemolysis, one has to separate the hemoglobin in blood plasma from that in red blood cells. However, current methods entail centrifugation for cell-plasma separation, which is complex, time-consuming, and not easy to integrate into point-of-care (PoC) systems. Here, we demonstrate an optofluidic sensor composed of nanofilters on an optical waveguide, which enables evanescent-wave absorption measurement of hemoglobin in plasma with the capability of real-time inline detection on whole blood without extra sample preparation like centrifugation. Long-term testing with inline integration in a modified, commercial blood gas analyzer shows high reliability and repeatability of the measurements even with the presence of interference from bilirubin. We envision that the present work has large potential in improving diagnosis quality by enabling PoC hemolysis detection in blood gas analyzers and can also lend unique sensing capabilities to other applications dealing with complex turbid media. PMID- 29473738 TI - Surface Charge Modulates Protein-Protein Interactions in Physiologically Relevant Environments. AB - Protein-protein interactions are fundamental to biology yet are rarely studied under physiologically relevant conditions where the concentration of macromolecules can exceed 300 g/L. These high concentrations cause cosolute complex contacts that are absent in dilute buffer. Understanding such interactions is important because they organize the cellular interior. We used 19F nuclear magnetic resonance, the dimer-forming A34F variant of the model protein GB1, and the cosolutes bovine serum albumin (BSA) and lysozyme to assess the effects of repulsive and attractive charge-charge dimer-cosolute interactions on dimer stability. The interactions were also manipulated via charge-change variants and by changing the pH. Charge-charge repulsions between BSA and GB1 stabilize the dimer, and the effects of lysozyme indicate a role for attractive interactions. The data show that chemical interactions can regulate the strength of protein-protein interactions under physiologically relevant crowded conditions and suggest a mechanism for tuning the equilibrium thermodynamics of protein protein interactions in cells. PMID- 29473739 TI - Mechanistic Implications of the Deamination of TDP-4-amino-4-deoxy-d-fucose Catalyzed by the Radical SAM Enzyme DesII. AB - DesII is a radical SAM lyase that catalyzes a deamination reaction during the biosynthesis of desosamine in Streptomyces venezuelae. Competing mechanistic hypotheses for this radical-mediated reaction are differentiated according to whether a 1,2-migration takes place and the timing of proton abstraction following generation of a substrate alpha-hydroxyalkyl radical intermediate. In this study, the deuterated C4 epimer of the natural substrate, TDP-4-amino-4 deoxy-d-[3-2H]fucose, was prepared and shown to be a substrate for DesII undergoing deamination alone with a specific activity that is only marginally reduced (~3-fold) with respect to that of deamination of the natural substrate. Furthermore, pH titration of the deamination reaction implicates the presence of a hydron acceptor that facilitates catalysis but does not appear to be necessary. On the basis of these as well as previously reported results, a mechanism involving direct elimination of ammonium with concerted proton transfer to the nucleofuge from the adjacent alpha-hydroxyalkyl radical is proposed.

AB - Despite the large body of work on {Ru(bpy)2} sensitizer fragments, the same attention has not been devoted to their {Ru(py)4} analogues. In this context, we explored the donor-acceptor trans-[Ru(L)4{(MU-NC)Cr(CN)5}2]4-, where L = pyridine, 4-methoxypyridine, 4-dimethylaminopyridine. We report on the synthesis and the crystal structure as well as the electrochemical, spectroscopical, and photophysical properties of these trimetallic complexes, including transient absorption measurements. We observed emission from chromium-centered d-d states upon illuminating into either MLCT or MM'CT absorptions of {Ru(L)4} or {Ru-Cr}, respectively. The underlying energy transfer is as fast as 600 fs with quantum efficiencies ranging from 10% to 100%. These results document that {Ru(py)4} sensitizer fragments are as efficient as {Ru(bpy)2} in short-range energy transfer scenarios.

AB - Semiempirical quantum mechanical (QM) methods with corrections for noncovalent interactions provide a favorable combination of accuracy and computational efficiency that makes them a useful tool for a study of large molecular systems. It was, however, noted that the accuracy of these methods deteriorates at intermolecular distances shorter than equilibrium. In this work, we explore this issue systematically using a newly developed data set of benchmark interaction energies named R160*6. This data set maps repulsive contacts in organic molecules, and it consists of 160 model complexes for which six points along the dissociation curve are provided. Testing a wide range of semiempirical QM methods against the CCSD(T)/CBS benchmark revealed that most methods, and all the dispersion-corrected ones, underestimate the repulsion systematically. The worst cases are usually hydrogen-hydrogen contacts. The best results were obtained with PM6-D3H4 and DFTB3-D3H4, as these methods already contain a correction for the H H repulsion, but the errors are still about twice as large as in equilibrium geometries. PMID- 29473743 TI - Dynamics and Function of Nuclear Bodies during Embryogenesis. AB - Nuclear bodies are RNA-rich membraneless organelles in the cell nucleus that concentrate specific sets of nuclear proteins and RNA-protein complexes. Nuclear bodies such as the nucleolus, Cajal body (CB), and the histone locus body (HLB) concentrate factors required for nuclear steps of RNA processing. Formation of these nuclear bodies occurs on genomic loci and is frequently associated with active sites of transcription. Whether nuclear body formation is dependent on a particular gene element, an active process such as transcription, or the nascent RNA present at gene loci is a topic of debate. Recently, this question has been addressed through studies in model organisms and their embryos. The switch from maternally provided RNA and protein to zygotic gene products in early embryos has been well characterized in a variety of organisms. This process, termed maternal to-zygotic transition, provides an excellent model for studying formation of nuclear bodies before, during, and after the transcriptional activation of the zygotic genome. Here, we review findings in embryos that reveal key principles in the study of the formation and function of nucleoli, CBs, and HLBs. We propose that while particular gene elements may contribute to formation of these nuclear bodies, active transcription promotes maturation of nuclear bodies and efficient RNA processing within them.

AB - Chlordecone is a synthetic organochlorine pesticide, extensively used in banana plantations of the French West Indies from 1972 to 1993. Due to its environmental persistence and bioaccumulation, it has dramatic public health and socio-economic impact. Here we describe a method for carbon-directed compound specific isotope analysis (CSIA) for chlordecone and apply it to monitor biotic and abiotic reductive transformation reactions, selected on the basis of their distinct product profiles (polychloroindenes versus lower chlorinated hydrochlordecones). Significant carbon isotopic enrichments were observed for all microbially mediated transformations (epsilonbulk = -6.80/00 with a Citrobacter strain and epsilonbulk = -4.60/00 with a bacterial consortium) and for two abiotic transformations (epsilonbulk = -4.10/00 with zerovalent iron and epsilonbulk = 2.60/00 with sodium sulfide and vitamin B12). The reaction with titanium(III) citrate and vitamin B12, which shows the product profile most similar to that observed in biotic transformation, led to low carbon isotope enrichment (epsilonbulk =-0.80/00). The CSIA protocol was also applied on representative chlordecone formulations previously used in the French West Indies, giving similar chlordecone delta13C values from -31.1 +/- 0.20/00 to -34.2 +/- 0.20/00 for all studied samples. This allows the in situ application of CSIA for the assessment of chlordecone persistence. PMID- 29473744 TI - Chemo- and Regioselective Lysine Modification on Native Proteins. AB - Site-selective chemical conjugation of synthetic molecules to proteins expands their functional and therapeutic capacity. Current protein modification methods, based on synthetic and biochemical technologies, can achieve site selectivity, but these techniques often require extensive sequence engineering or are restricted to the N- or C-terminus. Here we show the computer-assisted design of sulfonyl acrylate reagents for the modification of a single lysine residue on native protein sequences. This feature of the designed sulfonyl acrylates, together with the innate and subtle reactivity differences conferred by the unique local microenvironment surrounding each lysine, contribute to the observed regioselectivity of the reaction. Moreover, this site selectivity was predicted computationally, where the lysine with the lowest p Ka was the kinetically favored residue at slightly basic pH. Chemoselectivity was also observed as the reagent reacted preferentially at lysine, even in those cases when other nucleophilic residues such as cysteine were present. The reaction is fast and proceeds using a single molar equivalent of the sulfonyl acrylate reagent under biocompatible conditions (37 degrees C, pH 8.0). This technology was demonstrated by the quantitative and irreversible modification of five different proteins including the clinically used therapeutic antibody Trastuzumab without prior sequence engineering. Importantly, their native secondary structure and functionality is retained after the modification. This regioselective lysine modification method allows for further bioconjugation through aza-Michael addition to the acrylate electrophile that is generated by spontaneous elimination of methanesulfinic acid upon lysine labeling. We showed that a protein-antibody conjugate bearing a site-specifically installed fluorophore at lysine could be used for selective imaging of apoptotic cells and detection of Her2+ cells, respectively. This simple, robust method does not require genetic engineering and may be generally used for accessing diverse, well-defined protein conjugates for basic biology and therapeutic studies. PMID- 29473746 TI - Structures and Protonation States of Hydrophilic-Cationic Diblock Copolymers and Their Binding with Plasmid DNA. AB - Complexation between plasmid DNA (pDNA) and a set of diblock copolymers, each with one cationic block and one hydrophilic, charge-neutral block, is examined. A range of hydrophilic block structures are explored, whereas the cationic block is fixed as poly( N-(2-aminoethyl) methacrylamide) (PAEMA) with a degree of polymerization of 60 +/- 3. The hydrophilic blocks include poly(ethylene glycol) (PEG45), poly(oligo(ethylene glycol) methyl ether methacrylate) (P(OEGMA)51), and poly(2-deoxy-2-methacrylamido glucopyranose) (PMAG52). The numbers represent the degrees of polymerization and are chosen such that the diblock contour lengths are similar (37 +/- 2 nm). The three diblock copolymers and a homopolycation control, PAEMA59, are compared with respect to their state of dissolution in aqueous environments, as well as their complexation with pDNA. The diblock copolymers are found to partially aggregate as pH increases above 6, whereas each separate block generally dissolves well over a wide pH range. The hydrophilic block proves to be a critical parameter in determining the structures of pDNA diblock complexes. When the molar ratio of polycation amines to pDNA phosphates (i.e., N/P) is less than 1, a bulkier hydrophilic block leads to larger resulting complexes. As more polycations are added to the system (N/P > 1.5), colloidal stability becomes an important factor, making more water-soluble systems stabilize at smaller sizes. Further, the charge density effect on the binding thermodynamics is elucidated via calorimetric measurements. P(OEGMA)51- b-PAEMA60 exhibits a greater amount of endothermic pDNA binding per charged amine at higher pH, implying that lower cationic charge density promotes more phosphate pairing per amine on average. Also, the colloidal stability and the circular dichroism spectral evolution of the pDNA-PAEMA59 complexes are dependent on pH, showing noticeable differences between pH = 6.0 vs 7.4. To summarize, controlling the solution pH may be crucial in pDNA-polycation complexation, as it impacts polycation solubility, binding characteristics, and the final complex properties. The findings reported herein should aid researchers in drawing more rigorous structure-function correlations in the field of polymeric gene delivery. PMID- 29473747 TI - The Crystal Structure and Magnetic Behavior of Quinary Osmate and Ruthenate Double Perovskites La ABB'O6 ( A = Ca, Sr; B = Co, Ni; B' = Ru, Os). AB - Six La ABB'O6 ( A = Ca, Sr; B = Co, Ni; B' = Ru, Os) double perovskites were synthesized, several for the first time, and their crystal structures and magnetic behavior were characterized with neutron powder diffraction and direct current and alternating-current magnetometry. All six compounds crystallize with P21 /n space group symmetry, resulting from a- a- c+ octahedral tilting and complete rock salt ordering of transition-metal ions. Despite the electronic configurations of the transition-metal ions, either d8-d3 or d7-d3, not one of the six compounds shows ferromagnetism as predicted by the Goodenough-Kanamori rules. LaSrNiOsO6, LaSrNiRuO6, and LaCaNiRuO6 display long-range antiferromagnetic order, while LaCaNiOsO6, LaCaCoOsO6, and LaSrCoOsO6 exhibit spin-glass behavior. These compounds are compared to the previously studied LaCaCoRuO6 and LaSrCoRuO6, both of which order antiferromagnetically. The observed variations in magnetic properties can be attributed largely to the response of competing superexchange pathways due to changes in B-O- B' bond angles, differences in the radial extent of the 4d ( B' = Ru) and 5d ( B' = Os) orbitals, and filling of the t2g orbitals of the 3d ion. PMID- 29473748 TI - Comparison of Metal-Ammine Compounds Binding to DNA and Heparin. Glycans as Ligands in Bioinorganic Chemistry. AB - We present spectroscopic and biophysical approaches to examine the affinity of metal-ammine coordination complexes for heparin as a model for heparan sulfate (HS). Similar to nucleic acids, the highly anionic nature of heparin means it is associated in vivo with physiologically relevant cations, and this work extends their bioinorganic chemistry to substitution-inert metal-ammine compounds (M). Both indirect and direct assays were developed. M compounds are competitive inhibitors of methylene blue (MB)-heparin binding, and the change in the absorbance of the dye in the presence or absence of heparin can be used as an indirect reporter of M-heparin affinity. A second indirect assay uses the change in fluorescence of TAMRA-R9, a nonaarginine linked to a fluorescent TAMRA moiety, as a reporter for M-heparin binding. Direct assays are surface plasmon resonance (SPR) and isothermal titration calorimetry (ITC). The Kd values for TriplatinNC heparin varied to some extent depending on the technique from 33.1 +/- 2 nM (ITC) to 66.4 +/- 1.3 nM (MB absorbance assay) and 340 +/- 30 nM (SPR). The differences are explained by the nature of the technique and the use of heparin of differing molecular weight. Indirect probes using the displacement of ethidium bromide from DNA or, separately, fluorescently labeled oligonucleotide (DNA-Fl) can measure the relative affinities of heparin and DNA for M compounds. These assays showed essentially equivalent affinity of TriplatinNC for heparin and DNA. The generality of these methods was confirmed with a series of mononuclear cobalt, ruthenium, and platinum compounds with significantly lower affinity because of their smaller overall positive charge but in the order [Co(NH3)6]3+ > [Ru(NH3)6]3+ > [Pt(NH3)4]2+. The results on heparin can be extrapolated to glycosoaminoglycans such as HS, emphasizing the relevance of glycan interactions in understanding the biological properties of coordination compounds and the utility of the metalloglycomics concept for extending bioinorganic chemistry to this class of important biomolecules. PMID- 29473749 TI - Virtual Site OPLS Force Field for Imidazolium-Based Ionic Liquids. AB - Molecular simulations of ionic liquids can provide deeper insight into the relationship between intermolecular interactions and macroscopic measurements for the solvents. However, many existing force fields have multiple shortcomings, including poor solvent dynamics, the underestimation of hydrogen-bonding strength, and errors in solvent interactions/organization. A new force field, called optimized potentials for liquid simulation-ionic-liquid virtual site (OPLS VSIL), has been developed for imidazolium-based ionic liquids featuring a novel topology incorporating a virtual site bisecting the nitrogen atoms that offloads negative charge to inside the plane of the ring. Guided by free energy of hydration calculations, an empirically derived set of partial charges and nonbonded Lennard-Jones terms for both 1-alkyl-3-methylimidazolium and 11 different anions provided accurate bulk-phase ionic-liquid properties and produced radial distribution functions nearly indistinguishable from ab initio molecular dynamics simulations. For example, overall mean absolute errors (MAEs) of 3.1-3.4% were computed for the density, heat of vaporization, and viscosity of approximately 20 different ion pair combinations. Additional physical properties, such as, self-diffusion coefficients, heat capacity, and surface tension also gave significant MAE improvements using OPLS-VSIL compared to the existing fixed charge ionic-liquid force fields. Local interactions, including cation-anion hydrogen bonding and pi-pi stacking between the imidazolium rings, were also accurately reproduced. PMID- 29473750 TI - Excited States of Methylene, Polyenes, and Ozone from Heat-Bath Configuration Interaction. AB - The electronically excited states of methylene (CH2), ethylene (C2H4), butadiene (C4H6), hexatriene (C6H8), and ozone (O3) have long proven challenging due to their complex mixtures of static and dynamic correlations. The semistochastic heat-bath configuration interaction (SHCI) algorithm, which efficiently and systematically approaches the full configuration interaction (FCI) limit, is used to provide close approximations to the FCI energies in these systems. This article presents the largest FCI-level calculation to date on hexatriene, using a polarized double-zeta basis (ANO-L-pVDZ), which gives rise to a Hilbert space containing more than 1038 determinants. These calculations give vertical excitation energies of 5.58 and 5.59 eV, respectively, for the 21Ag and 11Bu states, showing that they are nearly degenerate. The same excitation energies in butadiene/ANO-L-pVDZ were found to be 6.58 and 6.45 eV. In addition to these benchmarks, our calculations strongly support the presence of a previously hypothesized ring-minimum species of ozone that lies 1.3 eV higher than the open ring-minimum energy structure and is separated from it by a barrier of 1.11 eV.

AB - Coordination cages were composed by self-organization of rigid C3 v-symmetric heptaarene tridentates and Pd(II) precursors. The heptaarene framework involves one mesitylene, three phenol, and three pyridine moieties, which were connected by Suzuki coupling reactions. The treatment of the tridentates with Pd(dppp)(OTf)2 or Pd(en)(NO3)2 in a 2:3 molar ratio furnished coordination cages, which was ascertained by crystallography, 1H NMR and DOSY measurements, and ESI TOFMS and UV-vis spectra. The cages have six phenolic hydroxy groups inside and were expected to incorporate hydrogen-bonding guest molecules such as saccharides. CD and DOSY measurements showed that octyl hexoside guests could be incorporated into the cage. PMID- 29473752 TI - Reaction Routes for Experimentally Observed Intermediates in the Prebiotic Formation of Nucleobases under High-Temperature Conditions. AB - The prebiotic synthesis of nucleobases is of particular interest, given the experimental evidence that indicated formation of the nucleobases under abiotic conditions on the Early Earth under high-temperature conditions. Biomolecules have been formed under meteoritic impact scenarios that lead to high temperature and the generation of high energy. Free radical pathways for the formation of biomolecules are appropriate under these conditions. Density functional theory computations were used to study the free radical routes for the formation of nucleobases at the UB3LYP/6-311G(d,p) level. We have found that both 5 aminoimidazole-4-carboxamide (AICA) and 5-(formylamino)imidazole-4-carboxamide (fAICA) are formed first from formamide then the nucleobases are formed. Calculated results show the radical reaction routes of AICA as a precursor for guanine. Both hypoxanthine and xanthine are formed from radical pathways of fAICA. In addition, generation of imino-AICA and imino-fAICA has been shown for the first time to be needed for the production of adenine, purine, and isoguanine. Formation of hypoxanthine and adenine/purine from fAICA and imino fAICA, respectively, is consistent with experiments performed nearly seven decades ago. PMID- 29473753 TI - Macrophage-Membrane-Coated Nanoparticles for Tumor-Targeted Chemotherapy. AB - Various delivery vectors have been integrated within biologically derived membrane systems to extend their residential time and reduce their reticuloendothelial system (RES) clearance during systemic circulation. However, rational design is still needed to further improve the in situ penetration efficiency of chemo-drug-loaded membrane delivery-system formulations and their release profiles at the tumor site. Here, a macrophage-membrane-coated nanoparticle is developed for tumor-targeted chemotherapy delivery with a controlled release profile in response to tumor microenvironment stimuli. Upon fulfilling its mission of tumor homing and RES evasion, the macrophage-membrane coating can be shed via morphological changes driven by extracellular microenvironment stimuli. The nanoparticles discharged from the outer membrane coating show penetration efficiency enhanced by their size advantage and surface modifications. After internalization by the tumor cells, the loaded drug is quickly released from the nanoparticles in response to the endosome pH. The designed macrophage-membrane-coated nanoparticle (cskc-PPiP/PTX@Ma) exhibits an enhanced therapeutic effect inherited from both membrane-derived tumor homing and step-by-step controlled drug release. Thus, the combination of a biomimetic cell membrane and a cascade-responsive polymeric nanoparticle embodies an effective drug delivery system tailored to the tumor microenvironment. PMID- 29473754 TI - Quantum Interference Assisted Spin Filtering in Graphene Nanoflakes. AB - We demonstrate that hexagonal graphene nanoflakes with zigzag edges display quantum interference (QI) patterns analogous to benzene molecular junctions. In contrast with graphene sheets, these nanoflakes also host magnetism. The cooperative effect of QI and magnetism enables spin-dependent quantum interference effects that result in a nearly complete spin polarization of the current and holds a huge potential for spintronic applications. We understand the origin of QI in terms of symmetry arguments, which show the robustness and generality of the effect. This also allows us to devise a concrete protocol for the electrostatic control of the spin polarization of the current by breaking the sublattice symmetry of graphene, by deposition on hexagonal boron nitride, paving the way to switchable spin filters. Such a system benefits from all of the extraordinary conduction properties of graphene, and at the same time, it does not require any external magnetic field to select the spin polarization, as magnetism emerges spontaneously at the edges of the nanoflake. PMID- 29473755 TI - Quantifying Local Molecular Tension Using Intercalated DNA Fluorescence. AB - The ability to measure mechanics and forces in biological nanostructures, such as DNA, proteins and cells, is of great importance as a means to analyze biomolecular systems. However, current force detection methods often require specialized instrumentation. Here, we present a novel and versatile method to quantify tension in molecular systems locally and in real time, using intercalated DNA fluorescence. This approach can report forces over a range of at least ~0.5-65 pN with a resolution of 1-3 pN, using commercially available intercalating dyes and a general-purpose fluorescence microscope. We demonstrate that the method can be easily implemented to report double-stranded (ds)DNA tension in any single-molecule assay that is compatible with fluorescence microscopy. This is particularly useful for multiplexed techniques, where measuring applied force in parallel is technically challenging. Moreover, tension measurements based on local dye binding offer the unique opportunity to determine how an applied force is distributed locally within biomolecular structures. Exploiting this, we apply our method to quantify the position-dependent force profile along the length of flow-stretched DNA and reveal that stretched and entwined DNA molecules-mimicking catenated DNA structures in vivo-display transient DNA-DNA interactions. The method reported here has obvious and broad applications for the study of DNA and DNA-protein interactions. Additionally, we propose that it could be employed to measure forces in any system to which dsDNA can be tethered, for applications including protein unfolding, chromosome mechanics, cell motility, and DNA nanomachines. PMID- 29473756 TI - 3D Molecular Representations Based on the Wave Transform for Convolutional Neural Networks. AB - Convolutional neural networks (CNN) have been successfully used to handle three dimensional data and are a natural match for data with spatial structure such as 3D molecular structures. However, a direct 3D representation of a molecule with atoms localized at voxels is too sparse, which leads to poor performance of the CNNs. In this work, we present a novel approach where atoms are extended to fill other nearby voxels with a transformation based on the wave transform. Experimenting on 4.5 million molecules from the Zinc database, we show that our proposed representation leads to better performance of CNN-based autoencoders than either the voxel-based representation or the previously used Gaussian blur of atoms and then successfully apply the new representation to classification tasks such as MACCS fingerprint prediction.

PMID- 29473758 TI - Arterial stiffness in women previously with preeclampsia from a semi-rural region of South Africa. AB - Women with pre-eclampsia have an increased risk of cardiovascular disease later in life. The aim of the study was to establish the presence and pattern of arterial stiffness in women previously with pre-eclampsia from a semi-rural region of South Africa. This was a prospective longitudinal study which involved 36 previously pre-eclamptic women and 86 non-pregnant controls (NPC) who had a past history of non-complicated pregnancy. Maternal wave reflection (augmentation index) and carotid-femoral pulse wave velocity were assessed noninvasively, using applanation tonometry with the SphygmoCor device. Endothelial function was assessed by EndoPAT 2000 device; pneumatic probes were fitted to the index fingers; induced flow-mediated reactive hyperemia; the ratio of the readings before and after occlusion was then used to calculate the score, the reactive hyperemia index (RHI) as a measure of endothelial function. Pulse wave velocity remained significantly higher in previously pre-eclamptic women than non-pregnant controls up to three months after delivery (p < 0.05), then it reduced to nonsignificant values. All blood pressure indices (central and brachial pressures), were higher in previously pre-eclamptic women as compared to nonpregnant controls up to one year postpartum. Regional (aortic) arterial stiffness, though it persists for some time after delivery, is transitory in previously pre-eclamptic women from the rural Africa setting. However, their increase blood pressure is an indication of compromised arterial compliance in women previously with pre-eclampsia. PMID- 29473759 TI - Contribution of non-traditional lipid profiles to reduced glomerular filtration rate in H-type hypertension population of rural China. AB - BACKGROUND: Despite current interest in the unfavourable impact of non traditional lipid profiles on cardiovascular disease, information regarding its relations to reduced glomerular filtration rate (GFR) in H-type hypertension population has not been systemically elucidated. METHODS: Analyses were based upon a cross-sectional study of 3259 participants with H-type hypertension who underwent assessment of biochemical, anthropometric and blood pressure values. Reduced GFR was considered if meeting estimated GFR <60 ml/min/1.73 m2. RESULTS: A stepwise multivariate regression analysis indicated that non-traditional lipid parameters remained as independent determinants of estimated GFR (all p < .001). In multivariable models, we observed a 50%, 51%, 31%, and 24% higher risk for decreased GFR with each SD increment in TC/HDL-C, TG/HDL-C, LDL-C/HDL-C ratios and non-HDL-C levels, respectively. The highest quartile of TC/HDL-C, TG/HDL-C and LDL-C/HDL-C ratios carried reduced GFR odds (confidence intervals) of 5.50 (2.50 to 12.09), 6.63 (2.58 to 17.05) and 2.22 (1.15 to 4.29), respectively. CONCLUSIONS: The relative independent contribution of non-traditional lipid profiles, as indexed by TC/HDL-C, TG/HDL-C, LDL-C/HDL-C ratios and non-HDL-C, towards reduced GFR putting research evidence at the very heart of lipoprotein mediated renal injury set a vital example for applying a clinical and public health recommendation for reducing the burden of chronic kidney disease. KEY MESSAGES Non-traditional lipid profiles has been linked with the occurrence of cardiovascular disease, but none of the studies that address the effect of non traditional lipid profiles on reduced GFR risk in H-type hypertension population has been specifically established. A greater emphasis of this study resided in the intrinsic value of TC/HDL-C, TG/HDL-C, LDL-C/HDL-C ratios and non-HDL-C that integrate atherogenic and anti-atherogenic lipid molecules to predict the risk of reduced GFR among H-type hypertension population and provide insight into the pathophysiology of subsequent cardio-cerebrovascular outcomes. In a large Chinese H-type hypertension adults, the relative independent contribution of non traditional lipid profiles, as indexed by TC/HDL-C, TG/HDL-C, LDL-C/HDL-C ratios and non-HDL-C, towards reduced GFR putting research evidence at the very heart of lipoprotein-mediated renal injury set a vital example for applying a clinical and public health recommendation for reducing the burden of CKD. PMID- 29473761 TI - Correlations between changes in hematological indices of mothers with preeclampsia and umbilical cord blood of newborns. AB - Preeclampsia is a condition that might severely impact the health of mothers and their newborns. The aim of this investigation is to examine hematological parameters in mothers with preeclampsia and umbilical cord blood. Eighty preecalmptic mothers were recruited in the study. In addition, eighty normal pregnant mothers served as controls. Hematological parameters that include hemoglobin (Hb), red blood cell count (RBC), red cell distribution width (RDW), packed cell volume (PCV), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), white blood cell counts (WBC), platelet counts, mean platelet volume (MPV) and Platelet large cell ratio (PLCR) were examined. Results showed a strong association between preeclampsia and low birth weight, premature/cesarean delivery and proteinuria (P < 0.001). Hb and neutrophils were significantly lower (P < 0.01), whereas RDW, PCV, MCV, MCH, MCHC and lymphocytes were significantly higher than normal ones (P < 0.01). When cord blood of preeclamptic mothers were compared with that of normal ones, similar findings were observed. In addition, results showed significant and positive correlations between preeclamptic mothers and their newborn in Hb (r2 = 0.075, P < 0.05), PCV (r2 = 0.084, P < 0.01), MCV (r2 = 0.077, P < 0.05), MCHC (r2 = 0.115, P < 0.01), RBC (r2 = 0.086, P < 0.01) and retics (r2 = 0.306, P < 0.01). In conclusion, changes in several hematological parameters associated with preeclampsia were correlated in affected mothers and their newborns. Such biomarkers can be used to predict pregnancy outcomes in women with preeclampsia. PMID- 29473760 TI - The acute effect of continuous positive airway pressure titration on blood pressure in awake overweight/obese patients with obstructive sleep apnoea. AB - OBJECTIVES: Continuous positive airway pressure (CPAP) improves upper airway obstruction in patients with obstructive sleep apnoea (OSA), who often are overweight-obese. Although it is thought that CPAP improves long-term blood pressure control (BP), the impact of acute and short-term CPAP use on the cardiovascular system in obese patients has not been described in detail. METHODS: Obese patients (body mass index, BMI > 25 kg/m2) with OSA were studied awake, supine during incremental CPAP titration (4-20 cmH2O, +2 cmH2O/3 mins). BP was measured continuously with a beat-to-beat BP monitor (Ohmeda 2300, Finapres Medical Systems, Amsterdam/NL), BP variability (BPV) was calculated as the standard deviation of BP at each CPAP level, the 95% confidence interval (95%CI) was calculated and changes in BP and BPV were reported. RESULTS: 15 patients (12 male, 48 +/- 10) years, BMI 38.9 +/- 5.8 kg/m2) were studied; the baseline BP was 131.0 +/- 10.2/85.1 +/- 9.1 mmHg. BP and BPV increased linearly with CPAP titration (systolic BP r = 0.960, p < .001; diastolic BP r = 0.961, p < .001; systolic BPV r = 0.662, p = .026; diastolic BPV r = 0.886, p < .001). The systolic BP increased by +17% (+23.15 (7.9, 38.4) mmHg; p = .011) and the diastolic BP by +23% (+18.27 (2.33, 34.21) mmHg; p = .009), when titrating CPAP to 20 cmH2O. Systolic BPV increased by +96% (+5.10 (0.67, 9.53) mmHg; p < .001) and was maximal at 14 cmH2O, and diastolic BPV by +97% (+3.02 (0.26, 5.78) mmHg; p < .001) at 16 cmH2O. CONCLUSION: Short-term incremental CPAP leads to significant increases in BP and BPV in obese patients with OSA while awake. Careful titration of pressures is required to minimise the risk of nocturnal awakenings while improving BP control.

AB - PURPOSE: To describe the trends in eye injuries and associated medical costs among children in the United States. METHODS: Data were from the 2002-2014 Medical Expenditure Panel Survey (MEPS). Eye injuries in children aged <18 years were identified by the International Classification of Diseases-9 (ICD-9) codes. The trends of cumulative incidence of eye injury, total costs, and average costs were estimated from 2002-2014 MEPS data. All costs were adjusted to 2014 US dollars. Analyses accounted for the complex stratified multistage survey design of the MEPS. We used MarketScan data (2010-2013) to validate outpatient cost estimates. RESULTS: The 3-year average cumulative incidence of eye injuries declined from 0.56% in 2002-2004 to 0.31% in 2012-2014 (Trend p < 0.001). The average annual total costs decreased from $193 million during 2002-2004 to $66 million during 2012-2014 (p < 0.001). CONCLUSION: The MEPS data showed that among children aged <18 years, the incidence of eye injuries and associated financial burden substantially declined during 2002-2014, highlighting the progress in preventing children eye injuries. Continuing efforts are needed to further reduce the burden in this population. PMID- 29473763 TI - Statin-induced myalgia and myositis: an update on pathogenesis and clinical recommendations. AB - INTRODUCTION: Musculoskeletal manifestations are well-recognized side effects of treatment with statins. New advances in this field have appeared in recent years. This review focuses on the diagnosis of these conditions and their underlying pathogenesis, in particular immune-mediated necrotizing myopathy. Areas covered: Clinical phenotypes including rhabdomyolysis, myalgia and/or mild hyperCKemia, self-limited toxin statin myopathy, and immune-mediated necrotizing myopathy are herein described. Therapeutic recommendations and a diagnostic algorithm in statin-associated myopathy are also proposed. The etiology and pathogenesis of statin-induced myopathy has mainly focused on the anti-HMGCR antibodies and the responsibility of the immune-mediated necrotizing myopathy is discussed. The fact that patients who have not been exposed to statins may develop statin-associated autoimmune myopathy with anti-HMGCR antibodies is also addressed. The literature search strategy included terms identified by searches of PubMed between 1969 and December 2017. The search terms 'myositis', 'statin-induced autoimmune myopathy', 'immune-mediate necrotizing myopathy', 'statins', 'muscular manifestations', and 'anti-HMGCR antibodies' were used. Expert commentary: Full characterization of the known phenotypes of statin toxicity and the specific role of the anti-HMGCR in those exposed and not exposed (i.e. juvenile forms) to statins and in some types of neoplasms is of paramount relevance. PMID- 29473764 TI - Effects of gestational diabetes mellitus on time to delivery and pregnancy outcomes in full-term pregnancies with dinoprostone labor induction. AB - OBJECTIVE: To investigate the effects of gestational diabetes mellitus (GDM) on time to delivery and perinatal outcomes in full-term pregnancies underwent dinoprostone-induced labor. METHODS: GDM patients that underwent labor induction with dinoprostone vaginal inserts were retrospectively recruited. Full-term pregnancies with normal glucose tolerance (NGT) that underwent labor induction at the same period were recruited as control. Time to delivery and perinatal outcomes were compared between the two groups. RESULTS: A total of 1555 pregnancies with 226 GDM and 1329 NGT were recruited. GDM pregnancies had older ages, lower gestational age, higher body mass index (BMI) and abortion history, and more multigravida than NGT pregnancies (P< 0.05). Univariate analysis showed no significant difference in time to delivery and delivery rates between the two groups. However, after adjusted in a multivariate analysis model, the delivery rates of GDM women delivered within 12, 24, 36 or 48 h and those vaginally delivered within 12 or 36 h were significantly lower than those in the NGT group (P< 0.05). Perinatal outcomes were clinically similar between the two groups. CONCLUSION: GDM did not affect the time to delivery, cesarean delivery and other perinatal outcomes in Chinese women underwent dinoprostone-induced labor. However, it may be associated with the lower rates of delivery within different time intervals. PMID- 29473765 TI - Antimicrobial molecules in the lung: formulation challenges and future directions for innovation. AB - Inhaled antimicrobials have been extremely beneficial in treating respiratory infections, particularly chronic infections in a lung with cystic fibrosis. The pulmonary delivery of antibiotics has been demonstrated to improve treatment efficacy, reduce systemic side effects and, critically, reduce drug exposure to commensal bacteria compared with systemic administration, reducing selective pressure for antimicrobial resistance. This review will explore the specific challenges of pulmonary delivery of a number of differing antimicrobial molecules, and the formulation and technological approaches that have been used to overcome these difficulties. It will also explore the future challenges being faced in the development of inhaled products and respiratory infection treatment, and identify future directions of innovation, with a particular focus on respiratory infections caused by multiple drug-resistant pathogens. PMID- 29473766 TI - Childcare Environment and Japanese Children Who Are Overweight in Early Childhood. AB - BACKGROUND: Maternal employment may affect child care styles and contribute to the increasing prevalence of overweight children. We explored the potential risk factors for becoming overweight during early childhood, especially in the child care environment. METHODS: We conducted a retrospective cohort study using data from health check-up services from 2007 to 2015 in Kobe, Japan. The main outcome was being overweight at age 3 years, which was defined by the International Obesity Task Force cutoffs. Environmental, maternal, and infantile factors were examined as possible risk factors for childhood overweight. RESULTS: Of 31,463 infants, 1315 (4.2%) were classified as overweight at age 3 years. Compared with children who were cared for by their mothers during the day at 4 and 18 months, the adjusted odds ratio (aOR) for becoming overweight for those who were not cared for by their mothers was 1.52: 95% confidence interval (CI), 1.16-1.99. Long sleep duration was associated with lower risk of childhood overweight: aOR, 0.79; 95% CI, 0.66-0.96. CONCLUSION: Less daytime care by mothers and shorter sleep duration were associated with increased risk of becoming overweight during childhood. Further studies are needed to determine on how the effect of those factors may be diminished with respect to childhood overweight. PMID- 29473767 TI - Computational modeling of blast induced whole-body injury: a review. AB - Blast injuries affect millions of lives across the globe due to its traumatic after effects on the brain and the whole body. To date, military grade armour materials are designed to mitigate ballistic and shrapnel attacks but are less effective in resisting blast impacts. In order to improve blast absorption characteristics of armours, the first key step is thoroughly understands the effects of blasts on the human body itself. In the last decade, a plethora of experimental and computational work has been carried out to investigate the mechanics and pathophysiology of Traumatic Brain Injury (TBI). However, very few attempts have been made so far to study the effect of blasts on the various other parts of the body such as the sensory organs (eyes and ears), nervous system, thorax, extremities, internal organs (such as the lungs) and the skeletal system. While an experimental evaluation of blast effects on such physiological systems is difficult, developing finite element (FE) models could allow the recreation of realistic blast scenarios on full scale human models and simulate the effects. The current article reviews the state-of-the-art in computational research in blast induced whole-body injury modelling, which would not only help in identifying the areas in which further research is required, but would also be indispensable for understanding body location specific armour design criteria for improved blast injury mitigation. PMID- 29473768 TI - Comparison of definitive-intent finely fractionated and palliative-intent coarsely fractionated radiotherapy as adjuvant treatment of feline microscopic injection-site sarcoma. AB - Objectives The aim of this retrospective, bi-institutional study was to evaluate the progression-free interval in a cohort of cats with postoperative microscopic injection-site sarcoma (ISS) treated with two different radiotherapy protocols. Methods Included in the study were cats with ISSs undergoing macroscopic surgical removal and subsequent electron beam radiotherapy treatment with either a finely fractionated protocol (48 or 52.8 Gy over 4 weeks delivered in 12 or 16 fractions) or a coarsely fractionated protocol (36 Gy over 3 weeks administered in six fractions). Medical records were reviewed and follow-up information was collected. The Kaplan-Meier method and log-rank test were used to compare the progression-free interval (PFI) between the two protocols and to test the influence of many clinical variables. Results Fifty-nine cats were included; 38 underwent a finely fractionated protocol and 21 a coarsely fractionated protocol. PFI was not significantly different between the two groups. Overall PFI was 2000 days (2000 vs 540 days; P = 0.449). When only first-occurrence cases were included, median PFI was significantly longer in the finely fractionated group compared with the coarsely fractionated group (1430 vs 540 days; P = 0.007). In cats that underwent multiple surgeries PFI was not different between protocols (233 vs 395 days; P = 0.353). Conclusions and relevance Cats with primarily occurring ISSs appear to benefit from postoperative finely fractionated radiotherapy. The same benefit was not evident in cats that underwent multiple surgeries and we think a coarsely fractionated protocol would be indicated in these cases. PMID- 29473769 TI - Identification and human exposure prediction of two aldehyde oxidase-mediated metabolites of a methylquinoline-containing drug candidate. AB - 1. Aldehyde oxidase (AO enzymes)-mediated oxidation predominantly occurs at a carbon atom adjacent to the nitrogen on aromatic azaheterocycles. In the current report, we identified that AO enzymes oxidation took place at both the C-2 and C 4 positions of the methylquinoline moiety of Compound A based on data from mass spectrometric analysis, AO enzymes "litmus" test, and comparison with authentic standards. 2. To assess the potential for inadequate coverage for these two AO enzyme-mediated metabolites in nonclinical safety studies, given concerns due to differences in AO enzymes expression between preclinical species and humans, the human circulating levels of the two AO enzyme-mediated metabolites were predicted prospectively using in vitro and in vivo models. Both formation clearance and elimination clearance of the two metabolites were predicted based on in vitro to in vivo correlation and comparison with in vivo data from rats. 3. The result showed that the 4-OH metabolite of Compound A would account for less than 3% of the total drug-related exposure in human plasma, while the exposure to the 2-oxo metabolite would be relatively high (~70%). 4. The predicted human exposure levels for the two metabolites are in similar ranges as those observed in monkeys. These data taken together support the advancement to clinical development of Compound A. PMID- 29473770 TI - Exploring Factors Contributing to Medication Errors with Opioids in Australian Specialist Palliative Care Inpatient Services: A Multi-Incident Analysis. AB - BACKGROUND: Opioid errors have the potential to cause significant patient harm. These high-risk medications are used in high volumes in palliative care services to manage pain and other symptoms. Palliative patients are at greater risk of harm from opioid errors, as they are generally older and taking numerous medications to manage multiple comorbidities. Understanding factors contributing to opioid errors in inpatient palliative care services is a largely underexplored, yet, essential aspect of patient safety. OBJECTIVE: To explore and identify the characteristics and associated contributing factors of reported opioid errors in palliative care inpatient services using a multi-incident analysis framework. DESIGN: A multi-incident analysis of opioid errors reported over three years in two Australian specialist palliative care inpatient services. RESULTS: A total of 78 opioid errors were reported. The majority (76%) of these errors occurred during opioid administration, primarily due to omitted dose (34%) and wrong dose (17%) errors. Eighty-five percent of reported errors reached the patient resulting in opioid underdose for over half (59%) of these patients. Over one-third (37%) of errors caused patient harm, which required clinical intervention. Error contributing factors included the following: noncompliance with policy; individual factors such as distraction; poor clinical communication systems; and workload. CONCLUSIONS: This multi-incident analysis has provided initial insights into factors contributing to opioid errors in palliative care inpatient services. Further exploration is warranted to understand palliative care clinicians' perspectives of systems, individual, and patient factors that influence safe opioid delivery processes. PMID- 29473771 TI - Illicit drug use and traumatic dental injuries in adolescents. AB - OBJECTIVE: To explore the association between illicit drug use and traumatic dental injuries (TDI) among adolescents. METHOD: We used data from 618 adolescents who participated in Phases I and III of Research with East Adolescents Community Health Survey (RELACHS), a longitudinal school-based study of adolescents in East London. Illicit drug use was collected when participants were 11-12 and 15-16 years old (Phases I and III, respectively). Clinical examinations for TDI were conducted in Phase III only. The association of lifetime prevalence of illicit drug use at ages 11-12 and 15-16 years with TDI was evaluated in crude and adjusted binary logistic regression models. RESULTS: Overall, 6.3% and 25.4% of adolescents reported having ever used illicit drugs at ages 11-12 (Phase I) and 15-16 years (Phase III), respectively. Also, 8.7% of adolescents were found to have TDI at age 15-16 years. There was no significant association between lifetime prevalence of illicit drug use reported at age 11-12 years (Odds Ratio: 1.07; 95% Confidence Interval: 0.45-2.54) or age 15-16 years (OR: 1.19; 95%CI: 0.74-1.93) and TDI. CONCLUSION: This study found no support for an association between illicit drug use and TDI among adolescents from East London. PMID- 29473772 TI - Letter to the Editor. Multiple meningiomas. PMID- 29473773 TI - MLN8237 treatment in an orthoxenograft murine model for malignant peripheral nerve sheath tumors. AB - OBJECTIVE Malignant peripheral nerve sheath tumors (MPNSTs) are soft-tissue sarcomas arising from peripheral nerves. MPNSTs have increased expression of the oncogene aurora kinase A, leading to enhanced cellular proliferation. This makes them extremely aggressive with high potential for metastasis and a devastating prognosis; 5-year survival estimates range from a dismal 15% to 60%. MPNSTs are currently treated with resection (sometimes requiring limb amputation) in combination with chemoradiation, both of which demonstrate limited effectiveness. The authors present the results of immunohistochemical, in vitro, and in vivo analyses of MLN8237 for the treatment of MPNSTs in an orthoxenograft murine model. METHODS Immunohistochemistry was performed on tumor sections to confirm the increased expression of aurora kinase A. Cytotoxicity analysis was then performed on an MPNST cell line (STS26T) to assess the efficacy of MLN8237 in vitro. A murine orthoxenograft MPNST model transfected to express luciferase was then developed to assess the efficacy of aurora kinase A inhibition in the treatment of MPNSTs in vivo. Mice with confirmed tumor on in vivo imaging were divided into 3 groups: 1) controls, 2) mice treated with MLN8237, and 3) mice treated with doxorubicin/ifosfamide. Treatment was carried out for 32 days, with imaging performed at weekly intervals until postinjection day 42. Average bioluminescence among groups was compared at weekly intervals using 1-way ANOVA. A survival analysis was performed using Kaplan-Meier curves. RESULTS Immunohistochemical analysis showed robust expression of aurora kinase A in tumor cells. Cytotoxicity analysis revealed STS26T susceptibility to MLN8237 in vitro. The group receiving treatment with MLN8237 showed a statistically significant difference in tumor size compared with the control group starting at postinjection day 21 and persisting until the end of the study. The MLN8237 group also showed decreased tumor size compared with the doxorubicin/ifosfamide group at the conclusion of the study (p = 0.036). Survival analysis revealed a significantly increased median survival in the MLN8237 group (83 days) compared with both the control (64 days) and doxorubicin/ifosfamide (67 days) groups. A hazard ratio comparing the 2 treatment groups showed a decreased hazard rate in the MLN8237 group compared with the doxorubicin/ifosfamide group (HR 2.945; p = 0.0134). CONCLUSIONS The results of this study demonstrate that MLN8237 is superior to combination treatment with doxorubicin/ifosfamide in a preclinical orthoxenograft murine model. These data have major implications for the future of MPNST research by providing a robust murine model as well as providing evidence that MLN8237 may be an effective treatment for MPNSTs.

PMID- 29473775 TI - Stereotactic radiosurgery for tremor: systematic review. AB - OBJECTIVE The aim of this systematic review is to offer an objective summary of the published literature relating to stereotactic radiosurgery (SRS) for tremor and consensus guideline recommendations. METHODS This systematic review was performed up to December 2016. Article selection was performed by searching the MEDLINE (PubMed) and EMBASE electronic bibliographic databases. The following key words were used: "radiosurgery" and "tremor" or "Parkinson's disease" or "multiple sclerosis" or "essential tremor" or "thalamotomy" or "pallidotomy." The search strategy was not limited by study design but only included key words in the English language, so at least the abstract had to be in English. RESULTS A total of 34 full-text articles were included in the analysis. Three studies were prospective studies, 1 was a retrospective comparative study, and the remaining 30 were retrospective studies. The one retrospective comparative study evaluating deep brain stimulation (DBS), radiofrequency thermocoagulation (RFT), and SRS reported similar tremor control rates, more permanent complications after DBS and RFT, more recurrence after RFT, and a longer latency period to clinical response with SRS. Similar tremor reduction rates in most of the reports were observed with SRS thalamotomy (mean 88%). Clinical complications were rare and usually not permanent (range 0%-100%, mean 17%, median 2%). Follow-up in general was too short to confirm long-term results. CONCLUSIONS SRS to the unilateral thalamic ventral intermediate nucleus, with a dose of 130-150 Gy, is a well-tolerated and effective treatment for reducing medically refractory tremor, and one that is recommended by the International Stereotactic Radiosurgery Society.

PMID- 29473777 TI - Quantitative and qualitative analysis of bone flap resorption in patients undergoing cranioplasty after decompressive craniectomy. AB - OBJECTIVE Autologous bone cranioplasty after decompressive craniectomy entails a notable burden of difficult postoperative complications, such as infection and bone flap resorption (BFR), leading to mechanical failure. The prevalence and significance of asymptomatic BFR is currently unclear. The aim of this study was to radiologically monitor the long-term bone flap survival and bone quality change in patients undergoing autologous cranioplasty. METHODS The authors identified all 45 patients who underwent autologous cranioplasty at Oulu University Hospital, Finland, between January 2004 and December 2014. Using perioperative and follow-up CT scans, the volumes and radiodensities of the intact bone flap prior to surgery and at follow-up were calculated. Relative changes in bone flap volume and radiodensity were then determined to assess cranioplasty survival. Sufficient CT scans were obtainable from 41 (91.1%) of the 45 patients. RESULTS The 41 patients were followed up for a median duration of 3.79 years (25th and 75th percentiles = 1.55 and 6.66). Thirty-seven (90.2%) of the 41 patients had some degree of BFR and 13 (31.7%) had a remaining bone flap volume of less than 80%. Patients younger than 30 years of age had a mean decrease of 15.8% in bone flap volume compared with the rest of the cohort. Bone flap volume was not found to decrease linearly with the passing of time, however. The effects of lifestyle factors and comorbidities on BFR were nonsignificant. CONCLUSIONS In this study BFR was a very common phenomenon, occurring at least to some degree in 90% of the patients. Decreases in bone volume were especially prominent in patients younger than 30 years of age. Because the progression of resorption during follow-up was nonlinear, routine follow-up CT scans appear unnecessary in monitoring the progression of BFR; instead, clinical follow-up with mechanical stability assessment is advised. Partial resorption is most likely a normal physiological phenomenon during the bone revitalization process. PMID- 29473778 TI - Assessment of the praxis circuit in glioma surgery to reduce the incidence of postoperative and long-term apraxia: a new intraoperative test. AB - OBJECTIVE Apraxia is a cognitive-motor deficit affecting the execution of skilled movements, termed praxis gestures, in the absence of primary sensory or motor disorders. In patients affected by stroke, apraxia is associated with lesions of the lateral parietofrontal stream, connecting the posterior parietal areas with the ventrolateral premotor area and subserving sensory-motor integration for the hand movements. In the neurosurgical literature to date, there are few reports regarding the incidence of apraxia after glioma surgery. A retrospective analysis of patients who harbored a glioma around the central sulcus and close to the parietofrontal circuits in depth showed a high incidence of long-term postoperative hand apraxia, impairing the patients' quality of life. To avoid the occurrence of postoperative apraxia, the authors sought to develop an innovative intraoperative hand manipulation task (HMt) that can be used in association with the brain mapping technique to identify and preserve the cortical and subcortical structures belonging to the praxis network. METHODS The intraoperative efficacy of the HMt was investigated by comparing the incidence of postoperative ideomotor apraxia between patients undergoing mapping with (n = 79) and without (n = 41) the HMt. Patient groups were balanced for all demographic and clinical features. RESULTS In patients with lesions in the dominant hemisphere, the HMt dramatically reduced the incidence of apraxia, with a higher sensitivity for the ideomotor than for the constructional abilities; patients with lesions in the nondominant hemisphere benefitted from the HMt for both ideomotor and constructional abilities. The administration of the test did not reduce the extent of resection. CONCLUSIONS The HMt is a safe and feasible intraoperative tool that allowed surgeons to prevent the occurrence of long-term hand apraxia while attaining resection goals for the surgical treatment of glioma. PMID- 29473779 TI - Impact of timing of ventriculoperitoneal shunt placement on outcome in posttraumatic hydrocephalus. AB - OBJECTIVE Posttraumatic hydrocephalus (PTH) is a frequent sequela of traumatic brain injury (TBI) and complication of related cranial surgery. The roles of PTH and the timing of cerebrospinal fluid (CSF) shunt placement in TBI outcome have not been well described. The goal of this study was to assess the impact of hydrocephalus and timing of ventriculoperitoneal (VP) shunt placement on outcome during inpatient rehabilitation after TBI. METHODS In this cohort study, all TBI patients admitted to Craig Hospital between 2009 and 2013 were evaluated for PTH, defined as ventriculomegaly, and hydrocephalus symptoms, delayed or deteriorating recovery, or elevated opening pressure on lumbar puncture. Extent of ventriculomegaly was quantified by the Evans index from CT scans. Outcome measures were emergence from and duration of posttraumatic amnesia (PTA) and functional status as assessed by means of the Functional Independence Measure (FIM). Findings in this group were compared to findings in a group of TBI patients without PTH (controls) who were admitted for inpatient rehabilitation during the same study period and met specific criteria for inclusion. RESULTS A total of 701 patients were admitted with TBI during the study period. Of these patients, 59 (8%) were diagnosed with PTH and were included in this study as the PTH group, and 204 who were admitted for rehabilitation and met the criteria for inclusion as controls constituted the comparison group (no-PTH group). PTH was associated with initial postinjury failure to follow commands, midline shift or cistern compression, subcortical contusion, and craniotomy or craniectomy. In multivariable analyses, independent predictors of longer PTA duration and lower FIM score at rehabilitation discharge were PTH, emergency department Glasgow Coma Scale motor score < 6, and longer time from injury to rehabilitation admission. PTH accounted for a 51-day increase in PTA duration and a 29-point reduction in discharge FIM score. In 40% of PTH patients with preshunt CT brain imaging analyzed, ventriculomegaly (Evans index > 0.3) was observed 3 or more days before VP shunt placement (median 10 days, range 3-102 days). Among PTH patients who received a VP shunt, earlier placement was associated with better outcome by all measures assessed and independently predicted better FIM total score and shorter PTA duration. CONCLUSIONS Posttraumatic hydrocephalus predicts worse outcome during inpatient rehabilitation, with poorer functional outcomes and longer duration of PTA. In shunt-treated PTH patients, earlier CSF shunting predicted improved recovery. These results suggest that clinical vigilance for PTH onset and additional studies on timing of CSF diversion are warranted. PMID- 29473780 TI - Letter to the Editor.

PMID- 29473781 TI - Prediction of depression and anxiety via patient-assessed tremor severity, not physician-reported motor symptom severity, in patients with Parkinson's disease or essential tremor who have undergone deep brain stimulation. AB - OBJECTIVE Deep brain stimulation (DBS) is an effective therapy for movement disorders such as idiopathic Parkinson's disease (PD) and essential tremor (ET). However, some patients who demonstrate benefit on objective motor function tests do not experience postoperative improvement in depression or anxiety, 2 important components of quality of life (QOL). Thus, to examine other possible explanations for the lack of a post-DBS correlation between improved objective motor function and decreased depression or anxiety, the authors investigated whether patient perceptions of motor symptom severity might contribute to disease-associated depression and anxiety. METHODS The authors performed a retrospective chart review of PD and ET patients who had undergone DBS at the Cleveland Clinic in the period from 2009 to 2013. Patient demographics, diagnosis (PD, ET), motor symptom severity, and QOL measures (Primary Care Evaluation of Mental Disorders 9-item Patient Health Questionnaire [PHQ-9] for depression, Generalized Anxiety Disorder 7-item Scale [GAD-7], and patient-assessed tremor scores) were collected at 4 time points: preoperatively, postoperatively, 1-year follow-up, and 2-year follow up. Multivariable prediction models with solutions for fixed effects were constructed to assess the correlation of predictor variables with PHQ-9 and GAD-7 scores. Predictor variables included age, sex, visit time, diagnosis (PD vs ET), patient-assessed tremor, physician-reported tremor, Unified Parkinson's Disease Rating Scale part III (UPDRS-III) score, and patient-assessed tremor over time. RESULTS Seventy PD patients and 17 ET patients were included in this analysis. Mean postoperative and 1-year follow-up UPDRS-III and physician-reported tremor scores were significantly decreased compared with preoperative scores (p < 0.0001). Two-year follow-up physician-reported tremor was also significantly decreased from preoperative scores (p < 0.0001). Only a diagnosis of PD (p = 0.0047) and the patient-assessed tremor rating (p < 0.0001) were significantly predictive of depression. A greater time since surgery, in general, significantly decreased anxiety scores (p < 0.0001) except when a worsening of patient-assessed tremor was reported over the same time period (p < 0.0013). CONCLUSIONS Patient assessed tremor severity alone was predictive of depression in PD and ET following DBS. This finding suggests that a patient's perception of illness plays a greater role in depression than objective physical disability regardless of the time since surgical intervention. In addition, while anxiety may be attenuated by DBS, patient-assessed return of tremor over time can increase anxiety, highlighting the importance of long-term follow-up for behavioral health features in chronic neurological disorders. Together, these data suggest that the patient experience of motor symptoms plays a role in depression and anxiety-a finding that warrants consideration when evaluating, treating, and following movement disorder patients who are candidates for DBS.

PMID- 29473783 TI - Anterior clinoidectomy using an extradural and intradural 2-step hybrid technique. AB - Anterior clinoidectomy is a difficult yet essential technique in skull base surgery. Two main techniques (extradural and intradural) with multiple modifications have been proposed to increase efficiency and avoid complications. In this study, the authors sought to develop a hybrid technique based on localization of the optic strut (OS) to combine the advantages and avoid the disadvantages of both techniques. Ten cadaveric specimens were prepared for surgical simulation. After a standard pterional craniotomy, the anterior clinoid process (ACP) was resected in 2 steps. The segment anterior to the OS was resected extradurally, while the segment posterior to the OS was resected intradurally. The proposed technique was performed in 6 clinical cases to evaluate its safety and efficiency. Anterior clinoidectomy was successfully performed in all cadaveric specimens and all 6 patients by using the proposed technique. The extradural phase enabled early decompression of the optic nerve while avoiding the adjacent internal carotid artery. The OS was drilled intradurally under direct visualization of the adjacent neurovascular structures. The described landmarks were easily identifiable and applicable in the surgically treated patients. No operative complication was encountered. A proposed 2-step hybrid technique combines the advantages of the extradural and intradural techniques while avoiding their disadvantages. This technique allows reduced intradural drilling and subarachnoid bone dust deposition. Moreover, the most critical part of the clinoidectomy-that is, drilling of the OS and removal of the body of the ACP-is left for the intradural phase, when critical neurovascular structures can be directly viewed. PMID- 29473784 TI - Strigolactones are common regulators in induction of stomatal closure in planta. AB - Strigolactones (SLs) have been implicated in many plant biological processes, including growth and development and the acclimation to environmental stress. We recently reported that SLs intrinsically acted as prominent regulators in induction of stomatal closure. Here we present evidence that the effect of SLs on stotamal closure is not limited to Arabidopsis, and thus SLs could serve as common regulators in the modulation of stomatal apertures of various plant species. Nevertheless, TIS108, a SL-biosynthetic inhibitor, exerted no effect on stomatal apertures. In addition, the SL receptor mutant atd14-5, similar to SL deficient and more axillary growth 2 (max2) mutants, exhibited hypersensitivity to drought stress. Altogether, these results reinforce the role of SLs as common regulators in stress resilience. PMID- 29473785 TI - Muscle morphology of the vastus lateralis is strongly related to ergometer performance, sprint capacity and endurance capacity in Olympic rowers. AB - Rowers need to combine high sprint and endurance capacities. Muscle morphology largely explains muscle power generating capacity, however, little is known on how muscle morphology relates to rowing performance measures. The aim was to determine how muscle morphology of the vastus lateralis relates to rowing ergometer performance, sprint and endurance capacity of Olympic rowers. Eighteen rowers (12?, 6?, who competed at 2016 Olympics) performed an incremental rowing test to obtain maximal oxygen consumption, reflecting endurance capacity. Sprint capacity was assessed by Wingate cycling peak power. M. vastus lateralis morphology (volume, physiological cross-sectional area, fascicle length and pennation angle) was derived from 3-dimensional ultrasound imaging. Thirteen rowers (7?, 6?) completed a 2000-m rowing ergometer time trial. Muscle volume largely explained variance in 2000-m rowing performance (R2 = 0.85), maximal oxygen consumption (R2 = 0.65), and Wingate peak power (R2 = 0.82). When normalized for differences in body size, maximal oxygen consumption and Wingate peak power were negatively related in males (r = -0.94). Fascicle length, not physiological cross-sectional area, attributed to normalized peak power. In conclusion, vastus lateralis volume largely explains variance in rowing ergometer performance, sprint and endurance capacity. For a high normalized sprint capacity, athletes may benefit from long fascicles rather than a large physiological cross-sectional area. PMID- 29473786 TI - Online measurement of phthalate-particulate matter interactions by membrane introduction mass spectrometry (MIMS). AB - To enable further study and assessment of indoor inhalation exposure risk, an online apparatus enabling measurement of semi-volatile compound partitioning on household particulates was developed. An example for use of the apparatus is described using dimethyl phthalate (DMP). The system employs direct measurement by membrane introduction mass spectrometry (MIMS). The MIMS system was calibrated using known gas phase DMP concentrations produced by gravimetrically calibrated permeation devices. The quantity of DMP sorbed by particles is described first using a model particle type, a reverse-phase liquid chromatography packing material, and then with a household dust sample. In addition, the desorption of semi-volatile compounds from a household dust sample was monitored using the apparatus, and characteristic fragment ion signals for phthalate compounds were observed. PMID- 29473787 TI - Identification of targeting peptides for the diagnosis of myocarditis. AB - AIM: Current diagnostic tests for myocarditis are invasive and have low diagnostic value. Our aim was to identify potential targeting peptides to detect early myocarditis following intravenous delivery. MATERIALS & METHODS: We used an animal model of experimental autoimmune myocarditis and a phage display library to identify potential targeting peptides. After several steps, we selected two peptides, MyH-PhD-05 and MyH-PhD-120, for in vivo screening using fluorescent imaging. Immunofluorescence and proteonomic analysis was used to identify potential cellular and molecular targets of MyH-PhD-05. Echocardiography was used to assess functional changes. RESULTS: Peptide MyH-PhD-05 was able to detect animals with severe myocarditis even in the absence of functional changes. Immunofluorescence demonstrated that MyH-PhD-05 colocalizes with CD4+ T cells and monocytes (CD11b+) in cardiac infiltrates. CONCLUSION: We identified potential targeting peptides for the diagnosis of myocarditis. Future studies will focus on better identification of potential targets and translating this technology to clinically relevant imaging modalities. PMID- 29473788 TI - Methylglyoxal induced advanced glycation end products (AGE)/receptor for AGE (RAGE)-mediated angiogenic impairment in bone marrow-derived endothelial progenitor cells. AB - Endothelial cells (ECs) maintain the structure and function of blood vessels and are readily exposed to exogenous and endogenous toxic substances in the circulatory system. Bone marrow-derived endothelial progenitor cells (EPCs) circulate in the blood and differentiate to EC, which are known to participate in angiogenesis and regeneration of injured vessels. Dysfunction in EPC contributes to cardiovascular complications in patients with diabetes, but the precise molecular mechanisms underlying diabetic EPC abnormalities are not completely understood. The aim of this study was to investigate the mechanisms underlying diabetic EPC dysfunction using methylglyoxal (MG), an endogenous toxic diabetic metabolite. Data demonstrated that MG decreased cell viability and protein expression of vascular endothelial growth factor receptor (VEGFR)-2 associated with functional impairment of tube formation in EPC. The generation of advanced glycation end (AGE) products was increased in EPC following exposure to MG. Blockage of receptor for AGE (RAGE) by FPS-ZM1, a specific antagonist for RAGE, significantly reversed the decrease of VEGFR-2 protein expression and angiogenic dysfunction in MG-incubated EPC. Taken together, data demonstrated that MG induced angiogenic impairment in EPC via alterations in the AGE/RAGE-VEGFR-2 pathway which may be utilized in the development of potential therapeutic and preventive targets for diabetic vascular complications. PMID- 29473789 TI - Ligament augmentation for prevention of proximal junctional kyphosis and proximal junctional failure in adult spinal deformity. AB - OBJECTIVE Proximal junctional kyphosis (PJK) is a well-recognized, yet incompletely defined, complication of adult spinal deformity surgery. There is no standardized definition for PJK, but most studies describe PJK as an increase in the proximal junctional angle (PJA) of greater than 10 degrees -20 degrees . Ligament augmentation is a novel strategy for PJK reduction that provides strength to the upper instrumented vertebra (UIV) and adjacent segments while also reducing junctional stress at those levels. METHODS In this study, ligament augmentation was used in a consecutive series of adult spinal deformity patients at a single institution. Patient demographics, including age; sex; indication for surgery; revision surgery; surgical approach; and use of 3-column osteotomies, vertebroplasty, or hook fixation at the UIV, were collected. The PJA was measured preoperatively and at last follow-up using 36-inch radiographs. Data on change in PJA and need for revision surgery were collected. Univariate and multivariate analyses were performed to identify factors associated with change in PJA and proximal junctional failure (PJF), defined as PJK requiring surgical correction. RESULTS A total of 200 consecutive patients were included: 100 patients before implementation of ligament augmentation and 100 patients after implementation of this technique. The mean age of the ligament augmentation cohort was 66 years, and 67% of patients were women. Over half of these cases (51%) were revision surgeries, with 38% involving a combined anterior or lateral and posterior approach. The mean change in PJA was 6 degrees in the ligament augmentation group compared with 14 degrees in the control group (p < 0.001). Eighty-four patients had a change in PJA of less than 10 degrees . In a multivariate linear regression model, age (p = 0.016), use of hook fixation at the UIV (p = 0.045), and use of ligament augmentation (p < 0.001) were associated with a change in PJA. In a separate model, only ligament augmentation (OR 0.193, p = 0.012) showed a significant association with PJF. CONCLUSIONS Ligament augmentation represents a novel technique for the prevention of PJK and PJF. Compared with a well-matched historical cohort, ligament augmentation is associated with a significant decrease in PJK and PJF. These data support the implementation of ligament augmentation in surgery for adult spinal deformity, particularly in patients with a high risk of developing PJK and PJF. PMID- 29473790 TI - Extraforaminal approach of biportal endoscopic spinal surgery: a new endoscopic technique for transforaminal decompression and discectomy. AB - This study was performed to describe the extraforaminal approach of biportal endoscopic spinal surgery (BESS) as a new endoscopic technique for transforaminal decompression and discectomy and to demonstrate the clinical outcomes of this new procedure for the first time. Twenty-one patients (27 segments) who underwent the extraforaminal approach of BESS between March 2015 and April 2016 were enrolled according to the inclusion and exclusion criteria. The operative time (minutes/level) and complications after the procedure were recorded. The visual analog scale (VAS) score was checked to assess the degree of radicular leg pain preoperatively and at the time of the last follow-up. The modified Macnab criteria were used to examine the clinical outcomes at the time of the last follow-up. The mean duration of the follow-up period was 14.8 months (minimum duration 12 months). The mean operative time was 96.7 minutes for one level. The mean VAS score for radicular leg pain dropped from a preoperative score of 7.5 +/ 0.9 to a final follow-up score of 2.5 +/- 1.2 (p < 0.001). The final outcome according to the modified Macnab criteria was excellent in 5 patients (23.8%), good in 12 (57.2%), fair in 4 (19.0%), and poor in 0. Therefore, excellent or good results (a satisfied outcome) were obtained in 80.9% of the patients. Complications were limited to one dural tear (4.8%). The authors found that the extraforaminal approach of BESS was a feasible and advantageous endoscopic technique for the treatment of foraminal lesions, including stenosis and disc herniation. They suggest that this technique represents a useful, alternative, minimally invasive method that can be used to treat lumbar foraminal stenosis and disc herniation.

AB - We investigated an Italian OXA-181-producing Escherichia coli clinical isolate (ECS1_14) by whole-genome sequencing. The strain coharbored blaCTX-M-15, blaCMY 2, and qnrS1 genes; it belonged to ST410(Achtman)/ST692(Pasteur) and phylogroup A. The blaOXA-181 gene was harbored on a plasmid highly similar (99% identity) to the pOXA181_EC14828 plasmid, recently reported in China.

AB - Streptococcus agalactiae is a causal agent of bovine mastitis and is treated by beta-lactam antibiotics (BLAs). Compared to penicillin-resistant S. agalactiae from humans, resistant strains in bovine are rarely reported. In this study, we aimed to investigate BLA resistance and mutations in penicillin-binding proteins (PBPs) of S. agalactiae in central and northeast China. The minimum inhibitory concentrations (MICs) of 129 penicillin-resistant S. agalactiae isolates from cows with mastitis were determined, and the related PBP genes were detected and sequenced. All strains were unsusceptible to penicillin G and mostly resistant to ampicillin, cefalexin, and ceftiofur sodium. One hundred twenty-nine strains were divided into 4 clonal groups and 8 sequence types by multilocus sequence typing analysis. We found a set of new substitutions in PBP1B, PBP2B, and PBP2X from most strains isolated from three provinces. The strains with high PBP mutations showed a broader unsusceptible spectrum and higher MICs than those with few or single mutation. Our research indicates unpredicted mutations in the PBP genes of S. agalactiae isolated from cows with mastitis treated by BLAs. This screening is the first of S. agalactiae from cattle.

PMID- 29473794 TI - [Mutual guiding and following of movement - The interaction process in mobilisation based on the example of kinaesthetics: A qualitative study]. AB - Background: Mobility impairment is often seen as a reason for needing long-term care. Thus, promoting mobility becomes increasingly significant in nursing homes. The kinaesthetic approach offers a way to support nursing home residents in using their own resources to maintain or improve their mobility. Aim: The present study intends to identify the characteristics of the interaction between nursing home residents with impaired mobility and kinaesthetic trainers during mobilisation. Methods: This secondary analysis comprises nine video sequences interpreted according to Grounded Theory-principles. The findings are described in a basic model. Results: The interaction with nursing home residents is focused on adapted movement support. This assistance shows a positive effect on residents' self activity in the tracking process and in the context of other strategies. Intervening conditions like residents' daily constitution have an influence on nurses' kinaesthetic strategies. Thereby, nurses have to be highly competent in self-perception. Conclusion: Adapted movement support proves to be a phenomenon basing on the nurse-resident-interaction and allowing residents to actively participate in collaborative action.

AB - OBJECTIVE: To describe a case of severe hypertriglyceridemia in a patient receiving teriflunomide. METHODS: This is a case study. RESULTS: Our patient developed severe hypertriglyceridemia (>5000 mg/dL) while on teriflunomide. The drug was withdrawn. Resolution began over 3 weeks later. CONCLUSION: We describe the first probable case of teriflunomide-associated severe hypertriglyceridemia in a patient with multiple sclerosis, an adverse event previously associated with leflunomide in patients with rheumatologic diseases. Clinicians should be aware of this rare but potentially dangerous adverse event.

AB - N-nitrosodiethanolamine (NDELA), a type of nitrosamine, is a possible human carcinogen that may form in cosmetic products. The aim of this study was to examine the formation and inhibition of NDELA through chemical reactions of secondary amines including mono-ethanolamine, di-ethanolamine (DEA), and tri ethanolamine (TEA), and sodium nitrite (SN) under varying conditions such as pH, temperature, and fluorescent, ultraviolet (UV), and visual light (VIS) using liquid chromatography-mass spectroscopy. In a mixture of TEA and SN under acidic conditions pH 2, residual NDELA concentrations rose significantly under various storage conditions in the following order: 50 degrees C > 40 degrees C > UV (2 W/m2) > VIS (4000 lux) > fluorescent light > 25 degrees C > 10 degrees C. In a mixture of DEA and SN under the same acidic pH 2 conditions, NDELA formation was significantly elevated in the following order: UV (2 W/m2) > VIS (4000 lux) > 50 degrees C > 40 degrees C > fluorescent light > 25 degrees C > 10 degrees C. Inhibition of NDELA formation by d-mannitol, vitamin C (Vit C), or vitamin E (Vit E) was determined under varying conditions of pH, temperature, and fluorescent, UV, and VIS. At high concentrations of 100 or 1000 ug/ml, Vit E significantly decreased residual NDELA compared with control levels under acidic pH 2, but not under basic pH 6. Among various antioxidants, Vit E reacted more effectively with many nitrosating agents such as nitrate and nitrite found in cosmetic products. Therefore, to reduce NDELA, it is recommended that cosmetics be stored under cool/amber conditions and that Vit E or Vit C inhibitors of nitrosation be optimally added to cosmetic formulations at concentrations between 100 and 1000 ug/ml. PMID- 29473798 TI - Cytochrome P450 1B1 promotes cancer cell survival via specificity protein 1 (Sp1) mediated suppression of death receptor 4. AB - Cytochrome P450 1B1 (CYP1B1), a well-known oncogene, has garnered wide attention because of its tumor-specific expression pattern and actions as a carcinogenic factor. Although CYP1B1 might play a crucial role in carcinogenesis, the detailed molecular mechanisms underlying oncogenic involvement in cancer development remain unclear. The present study investigated the manner in which CYP1B1 promotes survival of various cancer cells. Treatment with 2,2',4,6' tetramethoxystilbene (TMS), a specific CYP1B1 inhibitor, significantly inhibited cell viability in human breast cancer and leukemia cell lines, including MCF-7, MDA-MB-231, HL-60, and U937 cells. In order to characterize the cellular functions of CYP1B1 associated with cancer cell survival, the relationship between this oncogene and death receptor 4 (DR4) was determined. Following induction or inhibition of CYP1B1, mRNA and protein expression levels of DR4 were measured, and this oncogene was found to significantly repress DR4 mRNA and protein expression. Further, the suppression of DR4 by CYP1B1 was restored with 5 aza-2'-deoxycytidine (5-aza-dC), a DNA methyltransferase inhibitor, indicating that DNA methylation may be involved in CYP1B1-mediated DR4 inhibition. Methylation-specific polymerase chain reaction (PCR) in CYP1B1-overexpressed HL 60 cells revealed that this oncogene induced hypermethylation on DR4 promoter. Interestingly, data showed that DR4 suppression of CYP1B1 is mediated by the DNA binding ability of specificity protein 1 (Sp1). These findings suggest that CYP1B1 promotes cancer cell survival through involvement of DNA methylation mediated DR4 inhibition and that Sp1 may act as key mediator required for oncogenic action. PMID- 29473799 TI - Learning, memory deficits, and impaired neuronal maturation attributed to acrylamide. AB - Acrylamide (ACR) is a neurotoxin known to produce neurotoxicity characterized by ataxia, skeletal muscle weakness, cognitive impairment, and numbness of the extremities. Previously, investigators reported that high-dose (50 mg/kg) ACR impaired hippocampal neurogenesis and increased neural progenitor cell death; however, the influence of subchronic environmentally relevant low dose-(2, 20, or 200 MUg/kg) ACRs have not been examined in adult neurogenesis or cognitive function in mice. Accordingly, the aim of the present study was to investigate whether low-dose ACR adversely affected mouse hippocampal neurogenesis and neurocognitive functions. Male C57BL/6 mice were orally administered vehicle or ACR at 2, 20, or 200 MUg/kg/day for 4 weeks. ACR did not significantly alter the number of newly generated cells or produce neuroinflammation or neuronal loss in hippocampi. However, behavioral studies revealed that 200 MUg/kg ACR produced learning and memory impairment. Furthermore, incubation of ACR with primary cultured neurons during the developmental stage was found to delay neuronal maturation without affecting cell viability indicating the presence of developmental neurotoxicity. These findings indicate that although exposure to in vivo low-dose ACR daily for 4 weeks exerted no apparent marked effect on hippocampal neurogenesis, in vitro observations in primary cultured neurons noted adverse effects on learning and memory impairment suggestive of neurotoxic actions.

AB - Although the Organization for Economic Cooperation and Development (OECD) has adopted several in vitro methods with reasonable predictive capacity, alternative methods for identifying skin sensitizers and non-sensitizers with reliability and simplicity are still required for more efficient and economic prediction. The present study was to design an in vitro system with the use of a beta galactosidase-expressing E. coli culture for simpler but sufficiently accurate classification of skin sensitizers and non-sensitizers. A LacZ gene-containing E. coli strain that is capable of producing beta-galactosidase enzyme was induced by isopropyl beta-D-1-thiogalactopyranoside with concomitant treatment with test chemicals. After 6-hr incubation, cells were lysed and beta-galactosidase enzyme activity was monitored colorimetrically by using O-nitrophenyl-D galactopyranoside as a substrate. Following optimization of several experimental conditions, 22 skin sensitizers and 11 non-sensitizers were examined to assess predictive capacity of this method. The results indicated that predictivity was as follows: 90.9% sensitivity, 81.8% specificity, and 87.9% accuracy, when 17.3% of control activity was used as the cut-off value to separate sensitizers from non-sensitizers. Data suggested that the current bacterial system expressing beta galactosidase may serve as a useful alternative test for classifying skin sensitizers and non-sensitizers, without the utilization of animals or mammalian cell cultures.

PMID- 29473803 TI - Messy but Fair: The ACA's Hospital Value-Based Purchasing Program and the Notice and-Comment Process. AB - The Centers for Medicare and Medicaid Services (CMS) promulgated a new Medicare program called the Value-Based Purchasing Program (VBPP) as part of the 2010 Affordable Care Act (ACA). Like many other regulatory agencies, CMS used the Notice-and-Comment process to issue proposed rules, solicit public comments, and then publish final rules. Conventional literature suggests that CMS should disproportionately favor business interests during the Notice-and-Comment process, mainly due to the business interests' greater resources and capacity to draft well-reasoned comments. However, this article argues against this presumption and contends instead that CMS listens equally well to both business interest comments and private citizen comments during the formation of the VBPP. With regard to the VBPP and the ACA, CMS appears to be resisting disproportionate sway by business interests and is instead privileging the ACA's goal of improving healthcare quality.

The purpose of the article is twofold: it (1) aims to communicate the biomedical principles that underlie the pandemic in a rigorous yet accessible format and (2) shows that an understanding of the interaction between a legal rule and medical science is essential if the intended meaning, purpose, and policy rationale of the rule are to be preserved. It illustrates the interaction between law and science by analyzing the application of a doctrine in medical malpractice to litigation involving HIV/AIDS. It then draws parallels to other emerging diseases and shows how the analysis can be generalized and extended to legal issues involving any novel disease. PMID- 29473813 TI - Tubular approach to minimally invasive microdiscectomy for pediatric lumbar disc herniation. AB - OBJECTIVE Lumbar disc herniation (LDH) in the pediatric population is rare and exhibits unique characteristics compared with adult LDH. There are limited data regarding the safety and efficacy of minimally invasive surgery (MIS) using tubular retractors in pediatric patients with LDH. Here, the outcomes of MIS tubular microdiscectomy for the treatment of pediatric LDH are evaluated. METHODS Twelve consecutive pediatric patients with LDH were treated with MIS tubular microdiscectomy at the authors' institution between July 2011 and October 2015. Data were gathered from retrospective chart review and from mail or electronic questionnaires. The Macnab criteria and the Oswestry Disability Index (ODI) were used for outcome measurements. RESULTS The mean age at surgery was 17 +/- 1.6 years (range 13-19 years). Seven patients were female (58%). Prior to surgical intervention, 100% of patients underwent conservative treatment, and 50% had epidural steroid injections. Preoperative low-back and leg pain, positive straight leg raise, and myotomal leg weakness were noted in 100%, 83%, and 67% of patients, respectively. The median duration of symptoms prior to surgery was 9 months (range 1-36 months). The LDH level was L5-S1 in 75% of patients and L4-5 in 25%. The mean +/- SD operative time was 90 +/- 21 minutes, the estimated blood loss was <= 25 ml in 92% of patients (maximum 50 ml), and no intraoperative or postoperative complications were noted at 30 days. The median hospital length of stay was 1 day (range 0-3 days). The median follow-up duration was 2.2 years (range 0-5.8 years). One patient experienced reherniation at 18 months after the initial operation and required a second same-level MIS tubular microdiscectomy to achieve resolution of symptoms. Of the 11 patients seen for follow-up, 10 patients (91%) reported excellent or good satisfaction according to the Macnab criteria at the last follow-up. Only 1 patient reported a fair level of satisfaction by using the same criteria. Seven patients completed an ODI evaluation at the last follow-up. For these 7 patients, the mean ODI low-back pain score was 19.7% (SEM 2.8%). CONCLUSIONS To the authors' knowledge, this is the longest outcomes study and the largest series of pediatric patients with LDH who were treated with MIS microdiscectomy using tubular retractors. These data suggest that MIS tubular microdiscectomy is safe and efficacious for pediatric LDH. Larger prospective cohort studies with longer follow-up are needed to better evaluate the long-term efficacy of MIS tubular microdiscectomy versus other open and MIS techniques for the treatment of pediatric LDH. PMID- 29473814 TI - Restoration of shoulder motion using single- versus dual-nerve repair in obstetrical brachial plexus injury. AB - OBJECTIVE The purpose of this study was to compare shoulder abduction and external rotation (ER) after single-nerve repair of the upper trunk alone versus dual-nerve repair of both the upper trunk and the suprascapular nerve. METHODS A retrospective chart review of a single surgeon's experience repairing obstetrical brachial plexus injuries between June 1995 and June 2015 was performed. Eight patients underwent repair of the upper trunk alone, and 10 patients underwent repair of the upper trunk and the suprascapular nerve. Shoulder abduction and ER ranges of motion (ROMs) (in degrees) were recorded preoperatively and postoperatively. Postoperative ROM and the difference in ROM gained after surgery were compared by independent t-test analysis. RESULTS The mean follow-up time was 161.4 weeks (range 62-514 weeks, SD 124.0 weeks). The mean patient age at the time of surgery was 31.3 weeks (range 19.9-47.0 weeks, SD 6.9 weeks). The mean postoperative shoulder abduction ROMs were 145.0 degrees (range 85 degrees -180 degrees , SD 39.4 degrees ) after single-nerve repair and 134.0 degrees (range 90 degrees -180 degrees , SD 30.3 degrees ) after dual-nerve repair (p = 0.51). The mean postoperative shoulder ER ROMs were 67.5 degrees (range 10 degrees -95 degrees , SD 28.8 degrees ) after single-nerve repair and 72.0 degrees (range 10 degrees -95 degrees , SD 31.3 degrees ) after dual-nerve repair (p = 0.76). CONCLUSIONS The authors found no difference in shoulder abduction and ER between patients who underwent single-nerve repair of the upper trunk alone and those who underwent dual-nerve repair of both the upper trunk and the suprascapular nerve. PMID- 29473815 TI - Incidence of symptomatic tethered spinal cord in pediatric patients presenting with neurofibromatosis types 1 and 2. AB - OBJECTIVE The relationship between a tethered cord (TC) and neurofibromatosis type 1 (NF1) and NF2 is not known. The purpose of this study was to define the incidence of TC in pediatric neurosurgical patients who present with NF. METHODS The authors performed a single-institution (tertiary care pediatric hospital) 10 year retrospective analysis of patients who were diagnosed with or who underwent surgery for a TC and/or NF. Clinical and radiological characteristics were analyzed, as was histopathology. RESULTS A total of 424 patients underwent surgery for a TC during the study period, and 67 patients with NF were seen in the pediatric neurosurgery clinic. Of these 67 patients, 9 (13%) were diagnosed with a TC, and filum lysis surgery was recommended. Among the 9 patients with NF recommended for TC-release surgery, 4 (44%) were female, the mean age was 8 years (range 4-14 years), the conus position ranged from L1-2 to L-3, and 3 (33%) had a filum lipoma, defined as high signal intensity on T1-weighted MR images. All 9 of these patients presented with neuromotor, skeletal, voiding, and/or pain-related symptoms. Histopathological examination consistently revealed dense fibroconnective tissue and blood vessels. CONCLUSIONS Despite the lack of any known pathophysiological relationship between NF and TC, the incidence of a symptomatic TC in patients with NF1 and NF2 who presented for any reason to this tertiary care pediatric neurosurgery clinic was 13%. Counseling patients and families regarding TC symptomatology might be indicated in this patient population. PMID- 29473816 TI - DNA methylation signatures of pulmonary arterial smooth muscle cells in chronic thromboembolic pulmonary hypertension. AB - Chronic thromboembolic pulmonary hypertension (CTEPH) is a life-threatening disease, which is often underpinned by vascular remodeling. Pulmonary arterial smooth muscle cells (PASMCs) are the main participants in vascular remodeling. However, their biological role in CTEPH is not entirely clear. In the present study, we analyzed the whole epigenome-wide DNA methylation profile of cultured PASMCs from CTEPH and control cell lines with the Illumina Human Methylation 450K BeadChip. A total of 6,829 significantly differentially methylated probes (DMPs) were detected between these two groups. Among these, 4,246 DMPs were hypermethylated, while 2,583 DMPs were hypomethylated. The functional enrichment analysis of 1,743 DMPs in the promoter regions and corresponding genes indicated that DNA hypermethylation and hypomethylation might be involved in the regulation of genes that have multifarious biological roles, including roles in cancer related diseases, the regulation of the actin cytoskeleton, cell adhesion, and pattern specification processes. The observed methylations were categorized into the most important functions, including those involved in cell proliferation, immunity, and migration. We speculate that these methylations were most likely involved in the possible pathophysiology of CTEPH. Gene interaction analysis pertaining to signal networks confirmed that PIK3CA and PIK3R1 were important mediators in these whole networks. The mRNA levels of PIK3CA, HIC1, and SSH1 were verified by qPCR and corresponded with DNA methylation differences. Understanding epigenetic features associated with CTEPH may provide new insights into the mechanism that underlie this condition. PMID- 29473817 TI - Na+/H+ exchanger isoform 1-induced osteopontin expression facilitates cardiac hypertrophy through p90 ribosomal S6 kinase. AB - Cardiovascular diseases are the leading cause of death worldwide. One in three cases of heart failure is due to dilated cardiomyopathy. The Na+/H+ exchanger isoform 1 (NHE1), a multifunctional protein and the key pH regulator in the heart, has been demonstrated to be increased in this condition. We have previously demonstrated that elevated NHE1 activity induced cardiac hypertrophy in vivo. Furthermore, the overexpression of active NHE1 elicited modulation of gene expression in cardiomyocytes including an upregulation of myocardial osteopontin (OPN) expression. To determine the role of OPN in inducing NHE1 mediated cardiomyocyte hypertrophy, double transgenic mice expressing active NHE1 and OPN knockout were generated and assessed by echocardiography and the cardiac phenotype. Our studies showed that hearts expressing active NHE1 exhibited cardiac remodeling indicated by increased systolic and diastolic left ventricular internal diameter and increased ventricular volume. Moreover, these hearts demonstrated impaired function with decreased fractional shortening and ejection fraction. Atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) mRNA was upregulated, and there was an increase in heart cell cross-sectional area confirming the cardiac hypertrophic effect. Moreover, NHE1 transgenic mice also showed increased collagen deposition, upregulation of CD44 and phosphorylation of p90 ribosomal s6 kinase (RSK), effects that were regressed in OPN knockout mice. In conclusion, we developed an interesting comparative model of active NHE1 transgenic mouse lines which express a dilated hypertrophic phenotype expressing CD44 and phosphorylated RSK, effects which were regressed in absence of OPN. PMID- 29473818 TI - Transcriptomic sequencing reveals diverse adaptive gene expression responses of human vascular smooth muscle cells to nitro-conjugated linoleic acid. AB - Nitro-conjugated linoleic acid (NO2-CLA) is formed by metabolic and inflammatory reactions of nitric oxide and nitrite, and represents the most abundant nitro fatty acid species in humans. These electrophilic fatty acid nitroalkene derivatives mediate pleiotropic cell signaling responses. Here, we report a systematic approach to investigate the effect of NO2-CLA on human coronary artery smooth muscle cells (hCASMC), based on the RNA-Seq and bioinformatics analysis. There were extensive differentially expressed genes in NO2-CLA vs. control (510) and NO2-CLA vs. CLA (272) treatment groups, respectively. Notably, only minimal alterations were observed in CLA vs. control conditions, indicating that the electrophilic character of NO2-CLA is requited to induce differential gene expression responses independently from native CLA. Functional enrichment analysis of differentially expressed genes reveals multiple cellular processes to be affected under NO2-CLA treatment, including cell proliferation, lipid metabolism, antioxidant and inflammatory-related gene expression responses. These findings reveal that nitro-fatty acid derivatives such as NO2-CLA regulate a broad array of adaptive gene expression responses by hCASMC. PMID- 29473820 TI - Transcriptional profiling of the clpX mutant in Bacillus anthracis reveals regulatory connection with the lrgAB operon. AB - ClpX functions as either an independent chaperone or a component of the ClpXP protease, a conserved intracellular protease that acts as a global regulator in the bacterial cell by degrading regulatory proteins, stress response proteins and rate-limiting enzymes. Previously, we found that loss of clpX in Bacillus anthracis Sterne leads to increased susceptibility to antimicrobial agents that target the cell envelope. The aim of this study was to identify genes within the regulatory network of clpX that contribute to antimicrobial resistance. Using microarray analysis, we found 119 genes that are highly differentially expressed in the ?clpX mutant, with the majority involved in metabolic, transport or regulatory functions. Several of these differentially expressed genes, including glpF, sigM, mrsA, lrgA and lrgB, are associated with cell wall-active antibiotics in other bacterial species. We focused on lrgA and lrgB, which form the lrgAB operon and are downregulated in ?clpX, because loss of lrgAB increases autolytic activity and penicillin susceptibility in Staphylococcus aureus. While we observed no changes in autolytic activity in either ?clpX or ?lrgAB B. anthracis Sterne, we find that both mutants have increased susceptibility to the antimicrobial peptide LL-37 and daptomycin. However, phenotypes between ?clpX and ?lrgAB are not identical as ?clpX also displays increased susceptibility to penicillin and nisin but ?lrgAB does not. Therefore, while decreased expression of lrgAB may be partially responsible for the increased antimicrobial susceptibility seen in the ?clpX mutant, disruption of other pathways must also contribute to this phenotype. PMID- 29473819 TI - Comamonas aquatilis sp. nov., isolated from a garden pond. AB - A beige-pigmented bacterial strain, SB30-Chr27-3T, isolated from a garden pond, was studied for its taxonomic position. Cells of the isolate were rod-shaped and stained Gram-negative. A comparison of the 16S rRNA gene sequence with the sequences of the type strains of the most closely related species showed that the strain belongs to the genus Comamonas and showed highest sequence similarities to the type strains of Comamonas jiangduensis (97.5 %), Comamonas aquatica (97.4 %) and Comamonas phosphati (97.3 %). The 16S rRNA gene sequence similarities to all other Comamonas species were below 97.0 %. The fatty acid profile of strain SB30 Chr27-3T consisted of the major fatty acids C16 : 0, C15 : 0iso 2-OH/ C16 : 1omega7c, C18 : 1omega7c/C18 : 1omega9c and, in a minor amount, C10 : 0 3-OH. Major compounds in the polar lipid profile were phosphatidylethanolamine, phosphatidylglycerol, phosphatidylserine and diphosphatidylglycerol. The quinone system was exclusively composed of ubiquinone Q-8. The polyamine pattern contained the major compounds putrescine, cadaverine and 2-hydroxyputrescine. These data and the differentiating biochemical properties indicated that isolate SB30-CHR27-3T represents a novel species of the genus Comamonas, for which we propose the name >Comamonas aquatilis sp. nov. with the type strain SB30-Chr27-3T (=CIP 111491T=CCM 8815T). PMID- 29473822 TI - RgsA, an RpoS-dependent sRNA, negatively regulates rpoS expression in Pseudomonas aeruginosa. AB - As a master regulator, the alternative sigma factor RpoS coordinates the transcription of genes associated with protection against environmental stresses in bacteria. In Pseudomonas aeruginosa, RpoS is also involved in quorum sensing and virulence. The cellular RpoS level is regulated at multiple levels, whereas the post-transcriptional regulation of rpoS in P. aeruginosa remains unclear. To identify and characterize small regulatory RNAs (sRNAs) regulating RpoS in P. aeruginosa, an sRNA library expressing a total of 263 sRNAs was constructed to examine their regulatory roles on rpoS expression. Our results demonstrate that rpoS expression is repressed by the RpoS-dependent sRNA RgsA at the post transcriptional level. Unlike OxyS, an sRNA previously known to repress rpoS expression under oxidative stress in Escherichia coli, RgsA represses rpoS expression during the exponential phase. This repression requires the RNA chaperone Hfq. Furthermore, the 71-77 conserved region of RgsA is necessary for full repression of rpoS expression, and the -25 to +27 region of rpoS mRNA is sufficient for RgsA-mediated rpoS repression. Together, our results not only add RgsA to the RpoS regulatory circuits but also highlight the complexity of interplay between sRNAs and transcriptional regulators in bacteria. PMID- 29473821 TI - Luteimonas rhizosphaerae sp. nov., isolated from the rhizosphere of Triticum aestivum L. AB - A Gram-stain-negative, rod-shaped bacterium, strain 4-12T, was isolated from the rhizosphere of Triticum aestivum L. from the Xiaokai River irrigation area, China. The isolate grew optimally at 30 degrees C, pH 7.5-8.0 and with 1.0 % (w/v) NaCl. Based on the 16S rRNA gene sequence and phylogenetic analysis, strain 4-12T belonged to the genus Luteimonas with the highest degree of 16S rRNA gene sequence similarity to Luteimonas tolerans UM1T (97.68 %), followed by Luteimonas terrae THG-MD21T (97.67 %), Lysobacter panaciterrae Gsoil 068T (97.21 %) and Luteimonas aestuarii B9T (97.16 %). However, the DNA-DNA relatedness values between strain 4-12T and closely related Luteimonas strains were well below 40 %. The average nucleotide identity and the Genome-to-Genome Distance Calculator also showed low relatedness (below 95 and 70 %, respectively) between strain 4-12T and the type strains in genus Luteimonas. Ubiquinone-8 was the predominant quinone. The major fatty acids were iso-C15 : 0, iso-C11 : 0, iso-C17 : 0 and iso-C17 : 1omega9c. Polar lipids were dominated by diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and unidentified phospholipids. The DNA G+C content was 69.5 %. According to the phenotypic, genetic and chemotaxonomic data, strain 4-12T is considered to represent a novel species in the genus Luteimonas, for which the name >Luteimonas rhizosphaerae sp. nov. is proposed, with strain 4-12T (=CCTCC AB 2016261T=KCTC 52585T) as the type strain.

AB - Eu-doped 70SiO2-23HfO2-7ZnO (mol%) glass-ceramic waveguides have been fabricated by sol-gel method as a function of heat-treatment temperatures for on-chip blue light emitting source applications. Structural evolution of spherical ZnO and spherical as well as rod-like HfO2 nanocrystalline structures have been observed with heat-treatments at different temperatures. Initially, in the as-prepared samples at 900 ?C, both, Eu2+ as well as Eu3+ ions are found to be present in the ternary matrix. With controlled heat-treatments of up to 1000 ?C for 2 h, local environment of Eu-ions become more crystalline in nature and the reduction of Eu3+ to Eu2+ takes place in such ZnO/HfO2 crystalline environments. In these ternary glass-ceramic waveguides, heat-treated at higher temperatures, the blue light emission characteristic, which is the signature of 4f 65d [Formula: see text] 4f 7 energy level transition of Eu2+ ions is found to be greatly enhanced. The as-prepared glass-ceramic waveguides exhibit a propagation loss of 0.4 +/- 0.2 dB cm-1 at 632.8 nm. Though the propagation losses increase with the growth of nanocrystals, the added functionalities achieved in the optimally heat-treated Eu-doped 70SiO2-23HfO2-7ZnO (mol%) waveguides, make them a viable functional optical material for the fabrication of on-chip blue-light emitting sources for integrated optic applications.

AB - We use a non-classical modified couple stress theory including the acceleration gradients (MCST-AG), to precisely demonstrate the size dependency of the mechanical properties of gallium nitride (GaN) nanowires (NWs). The fundamental elastic constants, Young's modulus and length scales of the GaN NWs were estimated both experimentally, using a novel experimental technique applied to atomic force microscopy, and theoretically, using atomic simulations. The Young's modulus, static and the dynamic length scales, calculated with the MCST-AG, were found to be 323 GPa, 13 and 14.5 nm, respectively, for GaN NWs from a few nanometers radii to bulk radii. Analyzing the experimental data using the classical continuum theory shows an improvement in the experimental results by introducing smaller error. Using the length scales determined in MCST-AG, we explain the inconsistency of the Young's moduli reported in recent literature, and we prove the insufficiency of the Young's modulus for predicting the mechanical behavior of GaN NWs.

AB - Spintronics is an analogue to electronics where the spin of the electron rather than its charge is functionally controlled for devices. The generation and detection of spin current without ferromagnetic or exotic/scarce materials are two of the biggest challenges for spintronics devices. In this study, we report a solution to the two problems of spin current generation and detection in Si. Using non-local measurement, we experimentally demonstrate the generation of helical dissipationless spin current using the spin-Hall effect. Contrary to the theoretical prediction, we observe the spin-Hall effect in both n-doped and p doped Si. The helical spin current is attributed to the site-inversion asymmetry of the diamond cubic lattice of Si and structure inversion asymmetry in a MgO/Si bilayer. The spin to charge conversion in Si is insignificant due to weak spin orbit coupling. For the efficient detection of spin current, we report spin to charge conversion at the MgO (1 nm)/Si (2 um) (p-doped and n-doped) thin film interface due to Rashba spin-orbit coupling. We detected the spin current at a distance of >100 um, which is an order of magnitude larger than the longest spin diffusion length measured using spin injection techniques. The existence of spin current in Si is verified from the coercivity reduction in a Co/Pd multilayer due to spin-orbit torque generated by spin current from Si.

AB - In this work MoS2 thin film was studied as a potential two-dimensional (2D) hole transporting material for fabrication of low-cost, durable and efficient perovskite solar cells. The thickness of MoS2 was studied as a potential factor in reaching high power conversion efficiency in perovskite solar cells. The thickness of the perovskite layer and the different metal back contacts gave distinct photovoltaic properties to the designed cells. The results show that a single sheet of MoS2 could considerably improve the power conversion efficacy of the device from 10.41% for a hole transport material (HTM)-free device to 20.43% for a device prepared with a 0.67 nm thick MoS2 layer as a HTM. On the back, Ag and Al collected the carriers more efficiently than Au due to the value of their metal contact work function with the TiO2 conduction band. The present work proposes a new architecture for the fabrication of low-cost, durable and efficient perovskite solar cells made from a low-cost and robust inorganic HTM and electron transport material. PMID- 29473827 TI - Absence of a long-range ordered magnetic ground state in Pr3Rh4Sn13 studied through specific heat and inelastic neutron scattering. AB - Signatures of absence of a long-range ordered magnetic ground state down to 0.36 K are observed in magnetic susceptibility, specific heat, thermal/electrical transport and inelastic neutron scattering data of the quasi-skutterudite compound Pr3Rh4Sn13 which crystallizes in the Yb3Rh4Sn13-type structure with a cage-like network of Sn atoms. In this structure, Pr3+ occupies a lattice site with D 2d point symmetry having a ninefold degeneracy corresponding to J = 4. The magnetic susceptibility of Pr3Rh4Sn13 shows only a weak temperature dependence below 10 K; otherwise remaining paramagnetic-like in the range, 10 K 300 K. From the inelastic neutron scattering intensity of Pr3Rh4Sn13 recorded at different temperatures, we identify excitations at 4.5(7) K, 5.42(6) K, 10.77(5) K, 27.27(5) K, 192.28(4) K and 308.33(3) K through a careful peak analysis. However, no signatures of long-range magnetic order are observed in the neutron data down to 1.5 K, which is also confirmed by the specific heat data down to 0.36 K. A broad Schottky-like peak is recovered for the magnetic part of the specific heat, C 4f, which suggests the role of crystal electric fields of Pr3+ . A crystalline electric field model consisting of 7 levels was applied to C 4f which leads to the estimation of energy levels at 4.48(2) K, 6.94(4) K, 11.23(8) K, 27.01(5) K, 193.12(6) K and 367.30(2) K. The CEF energy levels estimated from the heat capacity analysis are in close agreement with the excitation energies seen in the neutron data. The Sommerfeld coefficient estimated from the analysis of magnetic specific heat is [Formula: see text] mJ K-2 mol-Pr which suggests the formation of heavy itinerant quasi-particles in Pr3Rh4Sn13. Combining inelastic neutron scattering results, analysis of the specific heat data down to 0.36 K, magnetic susceptibility and, electrical and thermal transport, we establish the absence of long-range ordered magnetic ground state in Pr3Rh4Sn13.

AB - Using non-equilibrium Green's function formalism combined with density functional theory calculations, we investigate the significant changes in electronic and transport properties of triangle graphene spirals (TGSs) in response to external strain. Tunable negative differential resistance (NDR) behavior is predicted. The NDR bias region, NDR width, and peak-to-valley ratio can be well tuned by external strain. Further analysis shows that these peculiar properties can be attributed to the dispersion widths of the p z orbitals. Moreover, the conductance of TGSs is very sensitive to the applied stress, which is promising for applications in nanosensor devices. Our findings reveal a novel approach to produce tunable electronic devices based on graphene spirals. PMID- 29473829 TI - Ion transport by gating voltage to nanopores produced via metal-assisted chemical etching method. AB - In this work, we report a simple and low-cost way to create nanopores that can be employed for various applications in nanofluidics. Nano sized Ag particles in the range from 1 to 20 nm are formed on a silicon substrate with a de-wetting method. Then the silicon nanopores with an approximate 15 nm average diameter and 200 MUm height are successfully produced by the metal-assisted chemical etching method. In addition, electrically driven ion transport in the nanopores is demonstrated for nanofluidic applications. Ion transport through the nanopores is observed and could be controlled by an application of a gating voltage to the nanopores. PMID- 29473830 TI - Stability investigation of a high number density Pt1/Fe2O3 single-atom catalyst under different gas environments by HAADF-STEM. AB - Catalysis by supported single metal atoms has demonstrated tremendous potential for practical applications due to their unique catalytic properties. Unless they are strongly anchored to the support surfaces, supported single atoms, however, are thermodynamically unstable, which poses a major obstacle for broad applications of single-atom catalysts (SACs). In order to develop strategies to improve the stability of SACs, we need to understand the intrinsic nature of the sintering processes of supported single metal atoms, especially under various gas environments that are relevant to important catalytic reactions. We report on the synthesis of high number density Pt1/Fe2O3 SACs using a facial strong adsorption method and the study of the mobility of these supported Pt single atoms at 250 degrees C under various gas environments that are relevant to CO oxidation, water gas shift, and hydrogenation reactions. Under the oxidative gas environment, Fe2O3 supported Pt single atoms are stable even at high temperatures. The presence of either CO or H2 molecules in the gas environment, however, facilitates the movement of the Pt atoms. The strong interaction between CO and Pt weakens the binding between the Pt atoms and the support, facilitating the movement of the Pt single atoms. The dissociation of H2 molecules on the Pt atoms and their subsequent interaction with the oxygen species of the support surfaces dislodge the surface oxygen anchored Pt atoms, resulting in the formation of Pt clusters. The addition of H2O molecules to the CO or H2 significantly accelerates the sintering of the Fe2O3 supported Pt single atoms. An anchoring-site determined sintering mechanism is further proposed, which is related to the metal support interaction.

AB - Although the teres minor is often overlooked in a normal shoulder, it becomes a key component in maintaining shoulder function when other rotator cuff tendons fail. The teres minor maintains a balanced glenohumeral joint and changes from an insignificant to the most significant external rotator in the presence of major rotator cuff pathology. The presence or absence of the teres minor provides prognostic information on the outcomes of reverse total shoulder arthroplasty and tendon transfers. Clinical tests include the Patte test, the Neer dropping sign, the external rotation lag sign, and the Hertel drop sign. Advanced imaging of the teres minor can be used for classification using the Walch system. Understanding the function and pathology surrounding the teres minor is paramount in comprehensive management of the patient with shoulder pathology. Appropriate clinical examination and imaging of the teres minor are important for preoperative stratification and postoperative expectations. PMID- 29473832 TI - Motocross Injuries in Pediatric and Adolescent Patients. AB - Motocross is a popular sport in which participants ride a two-wheeled, motorized vehicle on an uneven 2-km track with natural or human-made obstacles. Participants compete at high rates of speed, and children as young as age 4 years compete in age-appropriate groups. Motocross is recognized as a strenuous sport with a high accident rate. Most injuries are musculoskeletal in nature. The most commonly injured areas are the forearm, clavicle, femur, and tibia. Many injuries require surgical treatment. Some patients sustain head trauma with loss of consciousness. Children should have age-appropriate training before participation is allowed. Adult supervision should occur at all times. Appropriate helmet fitting with assistance from an expert is associated with a decreased risk of concussion symptoms. Parents and coaches need to weigh the benefits of participation with the frequency of injuries, missed academic time, and the cost of medical treatment. PMID- 29473833 TI - Internal Fixation of Osteoporotic Bone. AB - Osteoporosis is one of the costliest conditions managed by orthopaedic surgeons. This condition, which is characterized by decreased bone density and thinning of cortical bone, is strongly influenced by complex signaling in both the hormonal and mechanical environments. Osteoporosis cannot be cured; instead, it can only be managed to decrease patient morbidity. Current pharmacologic treatments are aimed at minimizing bone turnover and have substantial side effects. Therefore, much work remains to find safer and more effective agents to restore bone density. In addition to the high incidence of fracture in elderly patients, many of the traditional fixation constructs used for repair of these fractures are not suitable for use in osteoporotic bone. Increased use of fixed-angle locking plates, intramedullary devices, and bone substitutes has greatly improved outcomes in these patients.

The skin biopsy was consistent with the diagnosis of neutrophilic dermatosis. Rechallenge with ibrutinib at full dose was followed by the recurrence of the same skin lesions, strongly suggesting a direct relationship.

AB - This national survey highlights graduate medical education funding sources for physical medicine and rehabilitation (PM&R) residency programs as well as perceived funding stability, alignment of the current funding and educational model, the need of further education in postacute care settings, and the practice of contemporary PM&R graduates as perceived by PM&R department/division chairs. Approximately half of the reported PM&R residency positions seem to be funded by Centers of Medicare and Medicaid Services; more than 40% of PM&R chairs believe that their residency program is undersized and nearly a quarter feel at risk for losing positions. A total of 30% of respondents report PM&R resident experiences in home health, 15% in long-term acute care, and 52.5% in a skilled nursing facility/subacute rehabilitation facility. In programs that do not offer these experiences, most chairs feel that this training should be included. In addition, study results suggest that most PM&R graduates work in an outpatient setting. Based on the results that chairs strongly feel the need for resident education in postacute care settings and that most graduates go on to practice in outpatient settings, there is a potential discordance for our current Centers of Medicare and Medicaid Services graduate medical education funding model being linked to the acute care setting. PMID- 29473838 TI - "Nano-Ginseng" for Enhanced Cytotoxicity AGAINST Cancer Cells. AB - Panax ginseng has high medicinal and health values. However, the various and complex components of ginseng may interact with each other, thus reducing and even reversing therapeutic effects. In this study, we designed and fabricated a novel "nano-ginseng" with definite ingredients, ginsenoside Rb1/protopanaxadiol nanoparticles (Rb1/PPD NPs), completely based on the protopanaxadiol-type extracts. The optimized nano-formulations demonstrated an appropriate size (~110 nm), high drug loading efficiency (~96.8%) and capacity (~27.9 wt %), long half time in systemic circulation (nine-fold longer than free PPD), better antitumor effects in vitro and in vivo, higher accumulation at the tumor site and reduced damage to normal tissues. Importantly, this process of "nano-ginseng" production is a simple, scalable, green economy process. PMID- 29473839 TI - Sulphated Flavonoids: Biosynthesis, Structures, and Biological Activities. AB - The great diversity of enzymatic reactions in plant secondary metabolism allows the continuous discovery of new natural compounds and derivatives. Flavonoids, for example, can be found as aglycone or as several sorts of glycosylated, acetylated, methylated, and sulphated derivatives. This review focuses on sulphated flavonoids, an uncommon group of flavonoid derivatives found in some plant families. This work presents a compilation of sulphated flavonoids and their natural sources reported in the literature. Biosynthetic aspects and biological activities have also been reviewed, showing that these particular kinds of natural compounds play an interesting role in plant metabolism, as well as being potential candidates for the development of new drugs. PMID- 29473840 TI - Adaptive Correlation Model for Visual Tracking Using Keypoints Matching and Deep Convolutional Feature. AB - Although correlation filter (CF)-based visual tracking algorithms have achieved appealing results, there are still some problems to be solved. When the target object goes through long-term occlusions or scale variation, the correlation model used in existing CF-based algorithms will inevitably learn some non-target information or partial-target information. In order to avoid model contamination and enhance the adaptability of model updating, we introduce the keypoints matching strategy and adjust the model learning rate dynamically according to the matching score. Moreover, the proposed approach extracts convolutional features from a deep convolutional neural network (DCNN) to accurately estimate the position and scale of the target. Experimental results demonstrate that the proposed tracker has achieved satisfactory performance in a wide range of challenging tracking scenarios. PMID- 29473842 TI - Antioxidant Activity and Protective Effects of Enzyme-Extracted Oudemansiella radiata Polysaccharides on Alcohol-Induced Liver Injury. AB - This work was to examine the antioxidation in vitro and hepatoprotective effects of enzyme-extracted Oudemansiella radiata polysaccharides (En-OPS) on alcohol induced liver damage in mice. The antioxidant activities were determined according to the scavenging effects of En-OPS on hydroxyl, superoxide, and 1,1 diphenyl-2-picrylhydrazyl (DPPH) radicals, and the level of reducing power. En OPS showed hepatoprotective activities on decreasing the serum levels of aspertate aminotransferase (AST), alamine aminotransferase (ALT), and alkaline phosphatase (ALP), as well as hepatic lipid levels of total cholesterol (TC) and triacylglycerols (TG). En-OPS treatment reversed the acute impairment induced by alcohol consumption, including reactive oxygen species (ROS) generation, malondialdehyde (MAD), and lipid peroxide (LPO) elevation; and superoxide dismutase (SOD), GSH peroxide (GSH-Px), catalase (CAT), and total antioxidant capacity (T-AOC) impairment. The En-OPS effectively ameliorated alcohol metabolism by activating alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH), and reducing cytochrome P450 2E1 (CYP2E1) levels. Furthermore, the histopathological observations also displayed that En-OPS could alleviate liver damage. These results indicated that En-OPS could be suitable to be an ingredient of preventing alcoholic liver diseases (ALD). In addition, the preliminary structure characteristics of En-OPS were also analyzed by Fourier transform infrared (FT-IR) spectroscopy and a gas chromatography-flame ionization detector (GC-FID). PMID- 29473841 TI - Bioenergetics of Mycobacterium: An Emerging Landscape for Drug Discovery. AB - Mycobacterium tuberculosis (Mtb) exhibits remarkable metabolic flexibility that enables it to survive a plethora of host environments during its life cycle. With the advent of bedaquiline for treatment of multidrug-resistant tuberculosis, oxidative phosphorylation has been validated as an important target and a vulnerable component of mycobacterial metabolism. Exploiting the dependence of Mtb on oxidative phosphorylation for energy production, several components of this pathway have been targeted for the development of new antimycobacterial agents. This includes targeting NADH dehydrogenase by phenothiazine derivatives, menaquinone biosynthesis by DG70 and other compounds, terminal oxidase by imidazopyridine amides and ATP synthase by diarylquinolines. Importantly, oxidative phosphorylation also plays a critical role in the survival of persisters. Thus, inhibitors of oxidative phosphorylation can synergize with frontline TB drugs to shorten the course of treatment. In this review, we discuss the oxidative phosphorylation pathway and development of its inhibitors in detail. PMID- 29473843 TI - Prevalence of Oral Clefts among Live Births in Gansu Province, China. AB - Background: Oral clefts (OCs) are common human birth defects. Children with OCs in underdeveloped regions are more likely to suffer from poverty and hardship in their future lives. Here, we attempted to estimate the prevalence of OCs among live births in Gansu Province in 2008 to understand the epidemiologic pattern of the disease. Methods: A cross-sectional study was conducted from January 2008 to December 2008 in Gansu Province. The live births delivered between January and December 2008 with OCs were investigated through face-to-face questionnaire survey. Results: A total of 468 infants with OCs were identified among 347,137 live births in 2008 in Gansu Province, which yielded a prevalence of 1.35 per 1000 live births. The majority of these cases were CL (cleft lip) (prevalence = 0.85 per 1000 live births), and the prevalence of CLP (cleft lip and palate) and CP (cleft palate) was 0.34 and 0.11 per 1000 live births, respectively. We also found that the prevalence of OCs in Jiayuguan (3.39 per 1000 live births) and Dingxi (2.71 per 1000 live births) was higher than those of other cities in Gansu Province. Additionally, we failed to detect significant correlation between economic conditions of the cities and the prevalence of OCs in our study. Conclusions: The prevalence of OCs among live births in Gansu Province in 2008 was higher than the prevalence of OCs in other provinces in China. The high prevalence may reflect the need for further etiological studies to explore the potential risk factors in this region. In addition, more subtype information needs to be collected in future prevalence studies for better understanding of the epidemiologic pattern of the disease. PMID- 29473844 TI - Antimicrobial and Antibiofilm Activity and Machine Learning Classification Analysis of Essential Oils from Different Mediterranean Plants against Pseudomonas aeruginosa. AB - Pseudomonas aeruginosa is a ubiquitous organism and opportunistic pathogen that can cause persistent infections due to its peculiar antibiotic resistance mechanisms and to its ability to adhere and form biofilm. The interest in the development of new approaches for the prevention and treatment of biofilm formation has recently increased. The aim of this study was to seek new non biocidal agents able to inhibit biofilm formation, in order to counteract virulence rather than bacterial growth and avoid the selection of escape mutants. Herein, different essential oils extracted from Mediterranean plants were analyzed for their activity against P. aeruginosa. Results show that they were able to destabilize biofilm at very low concentration without impairing bacterial viability. Since the action is not related to a bacteriostatic/bactericidal activity on P. aeruginosa, the biofilm change of growth in presence of the essential oils was possibly due to a modulation of the phenotype. To this aim, application of machine learning algorithms led to the development of quantitative activity-composition relationships classification models that allowed to direct point out those essential oil chemical components more involved in the inhibition of biofilm production. The action of selected essential oils on sessile phenotype make them particularly interesting for possible applications such as prevention of bacterial contamination in the community and in healthcare environments in order to prevent human infections. We assayed 89 samples of different essential oils as P. aeruginosa anti-biofilm. Many samples inhibited P. aeruginosa biofilm at concentrations as low as 48.8 ug/mL. Classification of the models was developed through machine learning algorithms.

AB - Salvadora persica L. is a popular chewing stick commonly known as "miswak". During our ongoing research activities on the chemical constituents of Salvadora persica roots, which is a new sulphur-containing imidazoline alkaloid 1,3 Dibenzyl-4-(1,2,3,4-tetrahydroxy-butyl)-1,3-dihydro-imidazole-2-thione, persicaline, (1) along with five known compounds (2-6) are identified. Compounds (2, 3) were reported for the first time from the family Salvadoraeceae. The structure of the new compound was established by extensive spectroscopic data and HR-MS. The antioxidant activities of the fractions and isolates were evaluated using different in vitro methods, such as DPPH, superoxide anion and nitric oxide radicals scavenging assays. Compound (1) showed a promising antioxidant activity with IC50 0.1, 0.08, and 0.09 uM in the three assays, respectively, comparable to ascorbic acid. PMID- 29473846 TI - Epigallocatechin Gallate Reduces Ischemia/Reperfusion Injury in Isolated Perfused Rabbit Hearts. AB - Cardioplegic arrest during heart operations is often used in cardiac surgery. During cardioplegia, the heart is subjected to a global ischemia/reperfusion injury. (-)-epigallocatechin gallate (EGCG), one of the main ingredients of green tea, seems to be beneficial in various cardiac diseases. Therefore, the aim of our study was to evaluate EGCG in a rabbit model of cardioplegic arrest. Twenty four mature Chinchilla rabbits were examined. Rabbit hearts were isolated and perfused according to Langendorff. After induction of cardioplegia (without and with 20 umol/L EGCG, n = 6 each) the hearts maintained arrested for 90-min. Thereafter, the hearts were re-perfused for 60 min. During the entire experiment hemodynamic and functional data were assessed. At the end of each experiment, left ventricular samples were processed for ATP measurements and for histological analysis. Directly after cessation of cardioplegia, all hearts showed the same decline in systolic and diastolic function. However, hearts of the EGCG-group showed a significantly faster and better hemodynamic recovery during reperfusion. In addition, tissue ATP-levels were significantly higher in the EGCG-treated hearts. Histological analysis revealed that markers of nitrosative and oxidative stress were significantly lower in the EGCG group. Thus, addition of EGCG significantly protected the cardiac muscle from ischemia/reperfusion injury. PMID- 29473847 TI - Impact of Storage Conditions on the Stability of Predominant Phenolic Constituents and Antioxidant Activity of Dried Piper betle Extracts. AB - The phenolic constituents in Piper betle are well known for their antioxidant potential; however, current literature has very little information on their stability under the influence of storage factors. Present study evaluated the stability of total phenolic content (TPC) and antioxidant activity together with individual phenolic constituents (hydroxychavicol, eugenol, isoeugenol and allylpyrocatechol 3,4-diacetate) present in dried Piper betle's extract under different storage temperature of 5 and 25 degrees C with and without light for a period of six months. Both light and temperature significantly influenced TPC and its corresponding antioxidant activity over time. More than 95% TPC and antioxidant activity was retained at 5 degrees C in dark condition after 180 days of storage. Hydroxychavicol demonstrated the best stability with no degradation while eugenol and isoeugenol displayed moderate stability in low temperature (5 degrees C) and dark conditions. 4-allyl-1,2-diacetoxybenzene was the only compound that underwent complete degradation. A new compound, 2,4-di tert-butylphenol, was detected after five weeks of storage only in the extracts exposed to light. Both zero-order and first-order kinetic models were adopted to describe the degradation kinetics of the extract's antioxidant activity. Zero order displayed better fit with higher correlation coefficients (R2 = 0.9046) and the half-life was determined as 62 days for the optimised storage conditions (5 degrees C in dark conditions). PMID- 29473848 TI - Bovine alpha-Lactalbumin Hydrolysates (alpha-LAH) Ameliorate Adipose Insulin Resistance and Inflammation in High-Fat Diet-Fed C57BL/6J Mice. AB - Obesity-induced adipose inflammation has been demonstrated to be a key cause of insulin resistance. Peptides derived from bovine alpha-lactalbumin have been shown to inhibit the activities of dipeptidyl peptidase IV (DPP-IV) and angiotensin converting enzyme (ACE), scavenge 2,2'-azinobis [3 ethylbenzothiazoline-6-sulfonate] (ABTS+) radical and stimulate glucagon-like peptide-2 secretion. In the present study, the effects of bovine alpha lactalbumin hydrolysates (alpha-LAH) on adipose insulin resistance and inflammation induced by high-fat diet (HFD) were investigated. The insulin resistance model was established by feeding C57BL/6J mice with HFD (60% kcal from fat) for eight weeks. Then, the mice were fed with HFD and bovine alpha-LAH of different doses (100 mg/kg b.w., 200 mg/kg b.w. and 400 mg/kg b.w.) for another 12 weeks to evaluate its protective effects against HFD-induced insulin resistance. The oral glucose tolerance test (OGTT) and intraperitoneal insulin tolerance test (ipITT) were conducted after intervention with alpha-LAH for 10 weeks and 11 weeks, respectively. Results showed that bovine alpha-LAH significantly reduced body weight, blood glucose, serum insulin, and HOMA-IR (homeostatic model assessment of insulin resistance) levels, lowered the area under-the-curve (AUC) during OGTT and ipITT, and downregulated inflammation related gene [tumor necrosis factor (TNF)-alpha, interleukin (IL)-6, monocyte chemoattractant protein (MCP)-1] expression in adipose tissues of HFD-fed C57BL/6J mice. Furthermore, bovine alpha-LAH also suppressed insulin receptor substrate 1 (IRS-1) serine phosphorylation (Ser307, Ser612), enhanced protein kinase B (known as Akt) phosphorylation, and inhibited the activation of inhibitor of kappaB kinase (IKK) and mitogen activated protein kinase (MAPK) signaling pathways in adipose tissues of HFD-fed C57BL/6J mice. These results suggested that bovine alpha-LAH could ameliorate adipose insulin resistance and inflammation through IKK and MAPK signaling pathways in HFD-fed C57BL/6J mice.

PMID- 29473850 TI - Reconstructing Phylogeny by Aligning Multiple Metabolic Pathways Using Functional Module Mapping. AB - Comparison of metabolic pathways provides a systematic way for understanding the evolutionary and phylogenetic relationships in systems biology. Although a number of phylogenetic methods have been developed, few efforts have been made to provide a unified phylogenetic framework that sufficiently reflects the metabolic features of organisms. In this paper, we propose a phylogenetic framework that characterizes the metabolic features of organisms by aligning multiple metabolic pathways using functional module mapping. Our method transforms the alignment of multiple metabolic pathways into constructing the union graph of pathways, builds mappings between functional modules of pathways in the union graph, and infers phylogenetic relationships among organisms based on module mappings. Experimental results show that the use of functional module mapping enables us to correctly categorize organisms into main categories with specific metabolic characteristics. Traditional genome-based phylogenetic methods can reconstruct phylogenetic relationships, whereas our method can offer in-depth metabolic analysis for phylogenetic reconstruction, which can add insights into traditional phyletic reconstruction. The results also demonstrate that our phylogenetic trees are closer to the classic classifications in comparison to existing classification methods using metabolic pathway data. PMID- 29473851 TI - Fast and Simple Analytical Method for Direct Determination of Total Chlorine Content in Polyglycerol by ICP-MS. AB - The fast and simple method for total chlorine determination in polyglycerols using low resolution inductively coupled plasma mass spectrometry (ICP-MS) without the need for additional equipment and time-consuming sample decomposition was evaluated. Linear calibration curve for 35Cl isotope in the concentration range 20-800 ug/L was observed. Limits of detection and quantification equaled to 15 ug/L and 44 ug/L, respectively. This corresponds to possibility of detection 3 ug/g and determination 9 ug/g of chlorine in polyglycerol using studied conditions (0.5% matrix-polyglycerol samples diluted or dissolved with water to an overall concentration of 0.5%). Matrix effects as well as the effect of chlorine origin have been evaluated. The presence of 0.5% (m/m) of matrix species similar to polyglycerol (polyethylene glycol-PEG) did not influence the chlorine determination for PEGs with average molecular weights (MW) up to 2000 Da. Good precision and accuracy of the chlorine content determination was achieved regardless on its origin (inorganic/organic). High analyte recovery level and low relative standard deviation values were observed for real polyglycerol samples spiked with chloride. Additionally, the Combustion Ion Chromatography System was used as a reference method. The results confirmed high accuracy and precision of the tested method.

AB - This study was focused on the description of interaction between Cu2+ ions and the 1:1 mono- and dirhamnolipid mixtures in the premicellar and aggregated state in water and 20 mM KCl solution at pH 5.5 and 6.0. The critical micelle concentration of biosurfactants was determined conductometrically and by the pH measurements. Hydrodynamic diameter and electrophoretic mobility were determined in micellar solutions using dynamic light scattering and laser Doppler electrophoresis, respectively. The copper immobilization by rhamnolipids, methylglycinediacetic acid (MGDA), and ethylenediaminetetraacetic acid (EDTA) was estimated potentiometrically for the Cu2+ to chelating agent molar ratio from 16:100 to 200:100. The degree of ion binding and the complex stability constant were calculated at a 1:1 metal to chelant molar ratio. The aggregates of rhamnolipids (diameter of 43-89 nm) were negatively charged. Biosurfactants revealed the best chelating activities in premicellar solutions. For all chelants studied the degree of metal binding decreased with the increasing concentration of the systems. The presence of K+ lowered Cu2+ binding by rhamnolipids, but did not modify the complex stability significantly. Immobilization of Cu2+ by biosurfactants did not cause such an increase of acidification as that observed in MGDA and EDTA solutions. Rhamnolipids, even in the aggregated form, can be an alternative for the classic chelating agents.

AB - The influence of calcination time on the phase transformation and crystallization kinetics of anodized titania nanotube arrays was studied using in-situ isothermal and non-isothermal synchrotron radiation diffraction from room temperature to 900 degrees C. Anatase first crystallized at 400 degrees C, while rutile crystallized at 550 degrees C. Isothermal heating of the anodized titania nanotubes by an increase in the calcination time at 400, 450, 500, 550, 600, and 650 degrees C resulted in a slight reduction in anatase abundance, but an increase in the abundance of rutile because of an anatase-to-rutile transformation. The Avrami equation was used to model the titania crystallization mechanism and the Arrhenius equation was used to estimate the activation energies of the titania phase transformation. Activation energies of 22 (10) kJ/mol for the titanium-to-anatase transformation, and 207 (17) kJ/mol for the anatase-to rutile transformation were estimated. PMID- 29473853 TI - Antioxidant Tocols as Radiation Countermeasures (Challenges to be Addressed to Use Tocols as Radiation Countermeasures in Humans). AB - Radiation countermeasures fall under three categories, radiation protectors, radiation mitigators, and radiation therapeutics. Radiation protectors are agents that are administered before radiation exposure to protect from radiation-induced injuries by numerous mechanisms, including scavenging free radicals that are generated by initial radiochemical events. Radiation mitigators are agents that are administered after the exposure of radiation but before the onset of symptoms by accelerating the recovery and repair from radiation-induced injuries. Whereas radiation therapeutic agents administered after the onset of symptoms act by regenerating the tissues that are injured by radiation. Vitamin E is an antioxidant that neutralizes free radicals generated by radiation exposure by donating H atoms. The vitamin E family consists of eight different vitamers, including four tocopherols and four tocotrienols. Though alpha-tocopherol was extensively studied in the past, tocotrienols have recently gained attention as radiation countermeasures. Despite several studies performed on tocotrienols, there is no clear evidence on the factors that are responsible for their superior radiation protection properties over tocopherols. Their absorption and bioavailability are also not well understood. In this review, we discuss tocopherol's and tocotrienol's efficacy as radiation countermeasures and identify the challenges to be addressed to develop them into radiation countermeasures for human use in the event of radiological emergencies. PMID- 29473855 TI - Children's Environmental Health in the Digital Era: Understanding Early Screen Exposure as a Preventable Risk Factor for Obesity and Sleep Disorders. AB - The quantity, accessibility and focus on child-targeted programming has exponentially increased since it entered American households in the early 1900s. It may have started with the television (TV), but technology has evolved and now fits in our pockets; as of 2017, 95% of American families own a smartphone. Availability and child-tailored content has subsequently led to a decrease in the age at initial screen exposure. The negative effects that accompany the current culture of early screen exposure are extensive and need to be considered as technology continues to enter the home and inundate social interactions. Increased levels of early screen exposure have been associated with decreased cognitive abilities, decreased growth, addictive behavior, poor school performance, poor sleep patterns, and increased levels of obesity. Research on the adverse effects of early screen exposure is mounting, but further epidemiological studies are still needed to inform prevention and regulation policies. PMID- 29473856 TI - Fast Determination of Yttrium and Rare Earth Elements in Seawater by Inductively Coupled Plasma-Mass Spectrometry after Online Flow Injection Pretreatment. AB - A method for daily monitoring of yttrium and rare earth elements (YREEs) in seawater using a cheap flow injection system online coupled to inductively coupled plasma-mass spectrometry is reported. Toyopearl AF Chelate 650M(r) resin permits separation and concentration of YREEs using a simple external calibration. A running cycle consumed 6 mL sample and took 5.3 min, providing a throughput of 11 samples per hour. Linear ranges were up to 200 ng kg-1 except Tm (100 ng kg-1). The precision of the method was <6% (RSDs, n = 5), and recoveries ranged from 93% to 106%. Limits of detection (LODs) were in the range 0.002 ng kg 1 (Tm) to 0.078 ng kg-1 (Ce). Good agreement between YREEs concentrations in CASS 4 and SLEW-3 obtained in this work and results from other studies was observed. The proposed method was applied to the determination of YREEs in seawater from the Jiulong River Estuary and the Taiwan Strait. PMID- 29473857 TI - Structural Dynamics of DPP-4 and Its Influence on the Projection of Bioactive Ligands. AB - Dipeptidyl peptidase-4 (DPP-4) is a target to treat type II diabetes mellitus. Therefore, it is important to understand the structural aspects of this enzyme and its interaction with drug candidates. This study involved molecular dynamics simulations, normal mode analysis, binding site detection and analysis of molecular interactions to understand the protein dynamics. We identified some DPP 4 functional motions contributing to the exposure of the binding sites and twist movements revealing how the two enzyme chains are interconnected in their bioactive form, which are defined as chains A (residues 40-767) and B (residues 40-767). By understanding the enzyme structure, its motions and the regions of its binding sites, it will be possible to contribute to the design of new DPP-4 inhibitors as drug candidates to treat diabetes. PMID- 29473859 TI - Impact on Clinical Management of After-Hours Emergent or Urgent Breast Ultrasonography in Patients with Clinically Suspected Breast Abscesses. AB - Newly diagnosed breast abscesses are generally treated as a medical emergency that may necessitate immediate interventional treatment. At our institution, there is no in-house after-hours coverage for breast ultrasonography. We could find no peer-reviewed studies on the cost-effectiveness or clinical management impact of on-call ultrasound technologist coverage for imaging of breast abscesses. The purposes of this study were to determine the incidence of breast abscess in patients with clinical findings highly suggestive of abscess, identify clinical factors associated with breast abscess in such patients, and determine the impact of after-hours emergent or urgent breast ultrasonography on the clinical management of breast abscesses in both outpatients and inpatients. We retrospectively reviewed 100 after-hours breast ultrasound studies performed at our tertiary care center from 2011 to 2015 for evaluation of a suspected breast abscess. Only 26% of our patients with clinically suspected abscess ultimately had a confirmed abscess. Factors associated with breast abscess were a palpable abnormality and a history of breast surgery within the eight weeks before presentation. After-hours diagnosis of an abscess was associated with after-hours clinical intervention. Of the 74 patients in whom after-hours ultrasound imaging showed no evidence of abscess, only three patients underwent after-hours drainage. Our findings support overnight and weekend breast ultrasound coverage in large tertiary care centers. PMID- 29473860 TI - Carcinoembryonic Antigen Serum Levels in Nonmelanoma Skin Cancer. AB - BACKGROUND: Carcinoembryonic antigen (CEA) is a glycoprotein, which is present in the foetal colon, some benign conditions and different malignancies, particularly in colon adenocarcinoma. We focused this study on non-melanoma skin cancer (NMSC). NMSC is a common malignancy and it is an important source of morbidity and death in the world. In this study we evaluated whether CEA level increases in NMSC. PATIENTS AND METHODS: A total of 566 patients with non-melanoma skin cancer (NMSC) were enrolled; 286 patients with NMSC showed CEA levels above normal values, and 280 showed CEA levels below normal values. Patients with high levels of CEA underwent abdominal ultrasound, gastro endoscopy, colonoscopy, and abdominal CT scans. RESULTS: We studied 566 patients, 286 were positive to CEA and 280 were negative. Of the 286 patients positive to CEA, 132 had basal cell carcinoma (64 patients had an associated cancer) and 154 had squamous cell carcinoma (75 patients were affected by cancer). Of the 280 patients negative to CEA, 130 had basal cell carcinoma (12 were associated with cancer), and 150 had squamous cell carcinoma (18 were associated with cancer). The mean age of the 566 case control subjects were 65-81 years. Of the 10 subjects that were the positive control for CEA, two had cancer. Of the 556 subjects that were the negative control for CEA, three had cancer. CONCLUSIONS: In patients that present high serum levels of CEA, we give attention to adenocarcinoma tumour first. The pattern of association may be attributable to bias because the group with NMSC were frequently evaluated than those with no history of NMSC. Our results showed that out of 286 patients that were CEA-positive, 139 had cancer, and of the 280 that were CEA-negative, 30 had cancer. Therefore, 20% of patients do not follow the trend. Other markers should be investigated. PMID- 29473858 TI - Indispensable Role of Proteases in Plant Innate Immunity. AB - Plant defense is achieved mainly through the induction of microbe-associated molecular patterns (MAMP)-triggered immunity (MTI), effector-triggered immunity (ETI), systemic acquired resistance (SAR), induced systemic resistance (ISR), and RNA silencing. Plant immunity is a highly complex phenomenon with its own unique features that have emerged as a result of the arms race between plants and pathogens. However, the regulation of these processes is the same for all living organisms, including plants, and is controlled by proteases. Different families of plant proteases are involved in every type of immunity: some of the proteases that are covered in this review participate in MTI, affecting stomatal closure and callose deposition. A large number of proteases act in the apoplast, contributing to ETI by managing extracellular defense. A vast majority of the endogenous proteases discussed in this review are associated with the programmed cell death (PCD) of the infected cells and exhibit caspase-like activities. The synthesis of signal molecules, such as salicylic acid, jasmonic acid, and ethylene, and their signaling pathways, are regulated by endogenous proteases that affect the induction of pathogenesis-related genes and SAR or ISR establishment. A number of proteases are associated with herbivore defense. In this review, we summarize the data concerning identified plant endogenous proteases, their effect on plant-pathogen interactions, their subcellular localization, and their functional properties, if available, and we attribute a role in the different types and stages of innate immunity for each of the proteases covered. PMID- 29473861 TI - Nutrient Limitation Inactivates Mrc1-to-Cds1 Checkpoint Signalling in Schizosaccharomyces pombe. AB - The S. pombe checkpoint kinase, Cds1, protects the integrity of stalled DNA replication forks after its phosphorylation at threonine-11 by Rad3 (ATR). Modified Cds1 associates through its N-terminal forkhead-associated domain (FHA) domain with Mrc1 (Claspin) at stalled forks. We report here that nutrient starvation results in post-translational changes to Cds1 and the loss of Mrc1. A drop in glucose after a down-shift from 3% to 0.1-0.3%, or when cells enter the stationary phase, triggers a sharp decline in Mrc1 and the accumulation of insoluble Cds1. Before this transition, Cds1 is transiently activated and phosphorylated by Rad3 when glucose levels fall. Because this coincides with the phosphorylation of histone 2AX at S129 by Rad3, an event that occurs towards the end of every unperturbed S phase, we suggest that a glucose limitation promotes the exit from the S phase. Since nitrogen starvation also depletes Mrc1 while Cds1 is post-translationally modified, we suggest that nutrient limitation is the general signal that promotes exit from S phase before it inactivates the Mrc1 Cds1 signalling component. Why Cds1 accumulates in resting cells while its activator Mrc1 declines is, as yet, unclear but suggests a novel function of Cds1 in non-replicating cells. PMID- 29473862 TI - Using a Second Order Sigma-Delta Control to Improve the Performance of Metal Oxide Gas Sensors. AB - Controls of surface potential have been proposed to accelerate the time response of MOX gas sensors. These controls use temperature modulations and a feedback loop based on first-order sigma-delta modulators to keep constant the surface potential. Changes in the surrounding gases, therefore, must be compensated by average temperature produced by the control loop, which is the new output signal. The purpose of this paper is to present a second order sigma-delta control of the surface potential for gas sensors. With this new control strategy, it is possible to obtain a second order zero of the quantization noise in the output signal. This provides a less noisy control of the surface potential, while at the same time some undesired effects of first order modulators, such as the presence of plateaus, are avoided. Experiments proving these performance improvements are presented using a gas sensor made of tungsten oxide nanowires. Plateau avoidance and second order noise shaping is shown with ethanol measurements. PMID- 29473863 TI - Applicability of the Nordic Occupational Skin Questionnaire for Screening Contact Dermatological Disorders in Sea Fishers. AB - This survey aimed to evaluate the applicability of the Nordic Occupational Skin Questionnaire (NOSQ) as a preliminary screening tool to investigate the presence of contact dermatological disorders in sea fishermen. The Italian version of the NOSQ was administered to 143 male fishermen working at an Apulia (Southern Italy) Fisheries, and 136 male workers who had never worked as sea fishers (controls). A significantly higher rate of frequency of transient itchy wheals on the hands, wrists, and forearms was recorded in the fishermen as compared to the controls (49.6% vs. 8.1%; p < 0.001), while there was no significant difference in the frequency of eczema (8.4% vs. 6.6%). In 46.1% of the fishermen, the onset of transient itchy wheals was associated with contact with specific agents and the most common causes were algae and aquatic plants (49.3%) and seabed sludge (25.3%). In conclusion, the administration of the NOSQ can be useful in preliminary screening for dermatitis in fishermen, although it could show a possible overestimation of the prevalence of transient itchy wheals. PMID- 29473865 TI - Bottom-Up Electrodeposition of Large-Scale Nanotwinned Copper within 3D Through Silicon Via. AB - This paper is the first to report a large-scale directcurrent electrodeposition of columnar nanotwinned copper within through silicon via (TSV) with a high aspect ratio (~4). With this newly developed technique, void-free nanotwinned copper array could be fabricated in low current density (30 mA/cm2) and convection conditions (300 rpm), which are the preconditions for copper deposition with a uniform deep-hole microstructure. The microstructure of a whole cross-section of deposited copper array was made up of (111) orientated columnar grains with parallel nanoscale twins that had thicknesses of about 22 nm. The hardness was also uniform along the growth direction, with 2.34 and 2.68 GPa for the top and bottom of the TSV, respectively. The gelatin additive is also first reported hereas a key factor in forming nanoscale twins by adsorbing on the cathode surface, in order to enhance the overpotential for cathodic reaction during the copper deposition process. PMID- 29473864 TI - Triterpenoid Saponins from Anemone rivularis var. Flore-Minore and Their Anti Proliferative Activity on HSC-T6 Cells. AB - Five previously undescribed triterpenoid saponins (1-5), along with eight known ones (6-13), were isolated from the whole plants of Anemone rivularis var. flore minore. Their structures were clarified by extensive spectroscopic data and chemical evidence. For the first time, the lupane-type saponins (3 and 12) were reported from the Anemone genus. The anti-proliferative activity of all isolated saponins was evaluated on hepatic stellate cells (HSC-T6). Saponins 12 and 13, which possess more monosaccharides than the others, displayed potent anti proliferative activity, with IC50 values of 18.21 and 15.56 MUM, respectively. PMID- 29473866 TI - Molecular Modeling Study for the Design of Novel Peroxisome Proliferator Activated Receptor Gamma Agonists using 3D-QSAR and Molecular Docking. AB - Type 2 diabetes is becoming a global pandemic disease. As an important target for the generation and development of diabetes mellitus, peroxisome proliferator activated receptor gamma (PPARgamma) has been widely studied. PPARgamma agonists have been designed as potential anti-diabetic agents. The advanced development of PPARgamma agonists represents a valuable research tool for diabetes therapy. To explore the structural requirements of PPARgamma agonists, three-dimensional quantitative structure-activity relationship (3D-QSAR) and molecular docking studies were performed on a series of N-benzylbenzamide derivatives employing comparative molecular field analysis (CoMFA), comparative molecular similarity indices analysis (CoMSIA), and surflex-dock techniques. The generated models of CoMFA and CoMSIA exhibited a high cross-validation coefficient (q2) of 0.75 and 0.551, and a non-cross-validation coefficient (r2) of 0.958 and 0.912, respectively. The predictive ability of the models was validated using external validation with predictive factor (r2pred) of 0.722 and 0.682, respectively. These results indicate that the model has high statistical reliability and good predictive power. The probable binding modes of the best active compounds with PPARgamma active site were analyzed, and the residues His323, Tyr473, Ser289 and Ser342 were found to have hydrogen bond interactions. Based on the analysis of molecular docking results, and the 3D contour maps generated from CoMFA and CoMSIA models, the key structural features of PPARgamma agonists responsible for biological activity could be determined, and several new molecules, with potentially higher predicted activity, were designed thereafter. This work may provide valuable information in further optimization of N-benzylbenzamide derivatives as PPARgamma agonists. PMID- 29473867 TI - Microwave Sensors for Breast Cancer Detection. AB - Breast cancer is the leading cause of death among females, early diagnostic methods with suitable treatments improve the 5-year survival rates significantly. Microwave breast imaging has been reported as the most potential to become the alternative or additional tool to the current gold standard X-ray mammography for detecting breast cancer. The microwave breast image quality is affected by the microwave sensor, sensor array, the number of sensors in the array and the size of the sensor. In fact, microwave sensor array and sensor play an important role in the microwave breast imaging system. Numerous microwave biosensors have been developed for biomedical applications, with particular focus on breast tumor detection. Compared to the conventional medical imaging and biosensor techniques, these microwave sensors not only enable better cancer detection and improve the image resolution, but also provide attractive features such as label-free detection. This paper aims to provide an overview of recent important achievements in microwave sensors for biomedical imaging applications, with particular focus on breast cancer detection. The electric properties of biological tissues at microwave spectrum, microwave imaging approaches, microwave biosensors, current challenges and future works are also discussed in the manuscript. PMID- 29473868 TI - Oncotargeting by Vesicular Stomatitis Virus (VSV): Advances in Cancer Therapy. AB - Modern oncotherapy approaches are based on inducing controlled apoptosis in tumor cells. Although a number of apoptosis-induction approaches are available, site specific delivery of therapeutic agents still remain the biggest hurdle in achieving the desired cancer treatment benefit. Additionally, systemic treatment induced toxicity remains a major limiting factor in chemotherapy. To specifically address drug-accessibility and chemotherapy side effects, oncolytic virotherapy (OV) has emerged as a novel cancer treatment alternative. In OV, recombinant viruses with higher replication capacity and stronger lytic properties are being considered for tumor cell-targeting and subsequent cell lysing. Successful application of OVs lies in achieving strict tumor-specific tropism called oncotropism, which is contingent upon the biophysical interactions of tumor cell surface receptors with viral receptors and subsequent replication of oncolytic viruses in cancer cells. In this direction, few viral vector platforms have been developed and some of these have entered pre-clinical/clinical trials. Among these, the Vesicular stomatitis virus (VSV)-based platform shows high promise, as it is not pathogenic to humans. Further, modern molecular biology techniques such as reverse genetics tools have favorably advanced this field by creating efficient recombinant VSVs for OV; some have entered into clinical trials. In this review, we discuss the current status of VSV based oncotherapy, challenges, and future perspectives regarding its therapeutic applications in the cancer treatment. PMID- 29473869 TI - Enantiomeric Mixtures in Natural Product Chemistry: Separation and Absolute Configuration Assignment. AB - Chiral natural product molecules are generally assumed to be biosynthesized in an enantiomerically pure or enriched fashion. Nevertheless, a significant amount of racemates or enantiomerically enriched mixtures has been reported from natural sources. This number is estimated to be even larger since the enantiomeric purity of secondary metabolites is rarely checked in the natural product isolation pipeline. This latter fact may have drastic effects on the evaluation of the biological activity of chiral natural products. A second bottleneck is the determination of their absolute configurations. Despite the widespread use of optical rotation and electronic circular dichroism, most of the stereochemical assignments are based on empirical correlations with similar compounds reported in the literature. As an alternative, the combination of vibrational circular dichroism and quantum chemical calculations has emerged as a powerful and reliable tool for both conformational and configurational analysis of natural products, even for those lacking UV-Vis chromophores. In this review, we aim to provide the reader with a critical overview of the occurrence of enantiomeric mixtures of secondary metabolites in nature as well the best practices for their detection, enantioselective separation using liquid chromatography, and determination of absolute configuration by means of vibrational circular dichroism and density functional theory calculations. PMID- 29473870 TI - Prevalence and Gender-Specific Influencing Factors of Hypertension among Chinese Adults: A Cross-Sectional Survey Study in Nanchang, China. AB - Hypertension has become the leading cause of death worldwide; data on hypertension among Nanchang adults are sparse. The aim of this study was to investigate the prevalence and gender-specific influencing factors of hypertension in adults in Nanchang, China. A cross-sectional survey was conducted with a representative sample of 2722 Chinese residents aged 18 years and above between May and September 2016, with a response rate of 92.4% (2516/2722). A stratified cluster sampling method was adopted in this study. Data on prevalence and influencing factors were obtained from a standard questionnaire and physical measurements. Univariate and multivariate logistic regressions were performed to analyze the influencing factors. The age-standardized prevalence was 19.8% (18.2 21.3) (male: 19.5% (18.0-21.1); female, 20.01% (18.5-21.6)). Factors positively associated with hypertension prevalence were past smoking, diabetes mellitus (DM), and overweight and obesity in both genders. Abdominal obesity and family history of cardiovascular diseases (CVD) were risk factors only in males; sleeping time and consumption of fresh vegetables and fruits were related to the prevalence of hypertension only in females. These findings will form the baseline information for the development of more effective approaches to enhance current prevention and control management of hypertension. PMID- 29473872 TI - Microstructural Evolution of AlCoCrFeNiSi High-Entropy Alloy Powder during Mechanical Alloying and Its Coating Performance. AB - High-entropy alloys (HEAs) are promising structural materials due to their excellent comprehensive performances. The use of mechanically alloyed powders to deposit HEA coatings through atmospheric plasma spraying (APS) is an effective approach that can broaden the application areas of the HEAs. In this paper, a ductility-brittleness AlCoCrFeNiSi system was chosen as an object of study, and the detailed evolution of the surface morphology, particle size distribution, and microstructure of the powder during mechanical alloying was investigated. An AlCoCrFeNiSi HEA coating was deposited using powder milled for 10 h, which can be used as an ideal feedstock for APS. The surface morphology, microstructure, microhardness, and wear behavior of the coating at room temperature were investigated. The results showed that as the milling time increased, the particle size first increased, and then decreased. At the milling time of 10 h, simple body-centered cubic (BCC) and face-centered cubic (FCC) solid solution phases were formed. After spraying, the lamellar structure inside a single particle disappeared. An ordered BCC phase was detected, and the diffraction peaks of the Si element also disappeared, which indicates that phase transformation occurred during plasma spraying. A transmission electron microscopy analysis showed that nanometer crystalline grains with a grain size of about 30 nm existed in the APS coating. For the coating, an average microhardness of 612 +/- 41 HV was obtained. Adhesive wear, tribo-oxidation wear, and slight abrasion wear took place during the wear test. The coating showed good wear resistance, with a volume wear rate of 0.38 +/- 0.08 * 10-4 mm3.N-1.m-1, which makes it a promising coating for use in abrasive environments. PMID- 29473871 TI - Impaired Cargo Clearance in the Retinal Pigment Epithelium (RPE) Underlies Irreversible Blinding Diseases. AB - Chronic degeneration of the Retinal Pigment Epithelium (RPE) is a precursor to pathological changes in the outer retina. The RPE monolayer, which lies beneath the neuroretina, daily internalises and digests large volumes of spent photoreceptor outer segments. Impaired cargo handling and processing in the endocytic/phagosome and autophagy pathways lead to the accumulation of lipofuscin and pyridinium bis-retinoid A2E aggregates and chemically modified compounds such as malondialdehyde and 4-hydroxynonenal within RPE. These contribute to increased proteolytic and oxidative stress, resulting in irreversible damage to post mitotic RPE cells and development of blinding conditions such as age-related macular degeneration, Stargardt disease and choroideremia. Here, we review how impaired cargo handling in the RPE results in their dysfunction, discuss new findings from our laboratory and consider how newly discovered roles for lysosomes and the autophagy pathway could provide insights into retinopathies. Studies of these dynamic, molecular events have also been spurred on by recent advances in optics and imaging technology. Mechanisms underpinning lysosomal impairment in other degenerative conditions including storage disorders, alpha synuclein pathologies and Alzheimer's disease are also discussed. Collectively, these findings help transcend conventional understanding of these intracellular compartments as simple waste disposal bags to bring about a paradigm shift in the way lysosomes are perceived. PMID- 29473873 TI - New Evidence on the Effect of Medical Insurance on the Obesity Risk of Rural Residents: Findings from the China Health and Nutrition Survey (CHNS, 2004-2011). AB - The obesity rate in China has risen significantly in the past few decades. While a number of causes for the rise in obesity have been explored, little attention has been paid to the role of health insurance per se. This study aims to investigate the impact of health insurance on the risk of obesity in rural China using longitudinal data from the China Health and Nutrition Survey (CHNS). We employed pooled ordinary least squares (OLS), probit estimation, and pooled two stage least squares (2SLS) for an instrumental variable (IV). The IV model revealed that New rural cooperative medical insurance (NRCMS) participation had a significant positive impact on people's tendency towards unhealthy lifestyles, for instances, high-fat food (8.01% for female and 7.35% for male), cigarette smoking (25% for male), heavy drinking (25% for female), sedentary activity (6.48 h/w for female and 6.48 h/w for male), waist circumference (1.97 cm for female and 1.80 cm for male), body mass index (0.58 kg/m2 for female), which in turn leads to an elevated probability of general obesity (51% for female) and abdominal obesity (24% for female and 20% for male). An "ex ante moral hazard" is prevalent in rural China, which should not be ignored by policymakers so as to minimize the related low efficiency in the process of promoting the universal coverage of insurance. PMID- 29473874 TI - Natural Alkaloids and Heterocycles as G-Quadruplex Ligands and Potential Anticancer Agents. AB - G-quadruplexes are four-stranded nucleic acid secondary structures that are formed in guanine-rich sequences. G-quadruplexes are widely distributed in functional regions of the human genome and transcriptome, such as human telomeres, oncogene promoter regions, replication initiation sites, and untranslated regions. Many G-quadruplex-forming sequences are found to be associated with cancer, and thus, these non-canonical nucleic acid structures are considered to be attractive molecular targets for cancer therapeutics with novel mechanisms of action. In this mini review, we summarize recent advances made by our lab in the study of G-quadruplex-targeted natural alkaloids and their derivatives toward the development of potential anticancer agents. PMID- 29473875 TI - Core Sulphate-Reducing Microorganisms in Metal-Removing Semi-Passive Biochemical Reactors and the Co-Occurrence of Methanogens. AB - Biochemical reactors (BCRs) based on the stimulation of sulphate-reducing microorganisms (SRM) are emerging semi-passive remediation technologies for treatment of mine-influenced water. Their successful removal of metals and sulphate has been proven at the pilot-scale, but little is known about the types of SRM that grow in these systems and whether they are diverse or restricted to particular phylogenetic or taxonomic groups. A phylogenetic study of four established pilot-scale BCRs on three different mine sites compared the diversity of SRM growing in them. The mine sites were geographically distant from each other, nevertheless the BCRs selected for similar SRM types. Clostridia SRM related to Desulfosporosinus spp. known to be tolerant to high concentrations of copper were members of the core microbial community. Members of the SRM family Desulfobacteraceae were dominant, particularly those related to Desulfatirhabdium butyrativorans. Methanogens were dominant archaea and possibly were present at higher relative abundances than SRM in some BCRs. Both hydrogenotrophic and acetoclastic types were present. There were no strong negative or positive co occurrence correlations of methanogen and SRM taxa. Knowing which SRM inhabit successfully operating BCRs allows practitioners to target these phylogenetic groups when selecting inoculum for future operations. PMID- 29473877 TI - Parameter Estimation of the Thermal Network Model of a Machine Tool Spindle by Self-made Bluetooth Temperature Sensor Module. AB - Thermal characteristic analysis is essential for machine tool spindles because sudden failures may occur due to unexpected thermal issue. This article presents a lumped-parameter Thermal Network Model (TNM) and its parameter estimation scheme, including hardware and software, in order to characterize both the steady state and transient thermal behavior of machine tool spindles. For the hardware, the authors develop a Bluetooth Temperature Sensor Module (BTSM) which accompanying with three types of temperature-sensing probes (magnetic, screw, and probe). Its specification, through experimental test, achieves to the precision +/-(0.1 + 0.0029|t|) degrees C, resolution 0.00489 degrees C, power consumption 7 mW, and size O40 mm * 27 mm. For the software, the heat transfer characteristics of the machine tool spindle correlative to rotating speed are derived based on the theory of heat transfer and empirical formula. The predictive TNM of spindles was developed by grey-box estimation and experimental results. Even under such complicated operating conditions as various speeds and different initial conditions, the experiments validate that the present modeling methodology provides a robust and reliable tool for the temperature prediction with normalized mean square error of 99.5% agreement, and the present approach is transferable to the other spindles with a similar structure. For realizing the edge computing in smart manufacturing, a reduced-order TNM is constructed by Model Order Reduction (MOR) technique and implemented into the real-time embedded system.

AB - Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by progressive loss of lower and upper motor neurons (MN) leading to muscle weakness, paralysis and eventually death. Although a highly varied etiology results in ALS, it broadly manifests itself as sporadic and familial forms that have evident similarities in clinical symptoms and disease progression. There is a tremendous amount of knowledge on molecular mechanisms leading to loss of MNs and neuromuscular junctions (NMJ) as major determinants of disease onset, severity and progression in ALS. Specifically, two main opposing hypotheses, the dying forward and dying back phenomena, exist to account for NMJ denervation. The former hypothesis proposes that the earliest degeneration occurs at the central MNs and proceeds to the NMJ, whereas in the latter, the peripheral NMJ is the site of precipitating degeneration progressing backwards to the MN cell body. A large body of literature strongly indicates a role for the immune system in disease onset and progression via regulatory involvement at the level of both the central and peripheral nervous systems (CNS and PNS). In this review, we discuss the earliest reported immune responses with an emphasis on newly identified immune players in mutant superoxide dismutase 1 (mSOD1) transgenic mice, the gold standard mouse model for ALS.

AB - l-Phosphinothricin (glufosinate or 2-amino-4-((hydroxy(methyl) phosphinyl) butyric acid ammonium salt (AHPB)), which is a structural analog of glutamate, is a recognized herbicide that acts on weeds through inhibition of glutamine synthetase. Due to the structural similarity between phosphinothricin and some bisphosphonates (BPs), this study focuses on investigating the possibility of repurposing phosphinothricin as a bisphosphonate analogue, particularly in two medicine-related activities: image probing and as an anti-cancer drug. As BP is a competitive inhibitor of human farnesyl pyrophosphate synthase (HFPPS), in silico molecular docking and dynamic simulations studies were established to evaluate the binding and stability of phosphinothricin with HFPPS, while the results showed good binding and stability in the active site of the enzyme in relation to alendronate. For the purpose of inspecting bone-tissue accumulation of phosphinothricin, a technetium (99mTc)-phosphinothricin complex was developed and its stability and tissue distribution were scrutinized. The radioactive complex showed rapid, high and sustained uptake into bone tissues. Finally, the cytotoxic activity of phosphinothricin was tested against breast and lung cancer cells, with the results indicating cytotoxic activity in relation to alendronate. All the above results provide support for the use of phosphinothricin as a potential anti-cancer drug and of its technetium complex as an imaging probe. PMID- 29473880 TI - Assessment and Treatment of Pediatric Sleep Problems: Knowledge, Skills, Attitudes and Practices in a Group of Community Child Psychiatrists. AB - As part of a university-based quality improvement project, we aimed to evaluate child psychiatrists' knowledge, skills, attitudes, and practices regarding assessment and treatment of pediatric sleep problems. We developed a nine question survey of knowledge, skills, attitudes, and practices regarding assessing for and treating sleep complaints in pediatric patients, and administered this survey to child psychiatrists in training and in practice in the state of Missouri. Respondents reported sleep hygiene as the first-line treatment strategy, followed by the use of supplements or over-the-counter remedies. The most common barriers to evidence-based assessment and treatment of sleep problems were the lack of ability to obtain reliable history, and parental preference for medications over behavioral approaches for sleep concerns. These results suggest potential opportunities for enhancing knowledge regarding validated assessment tools and non-pharmacological treatment options for sleep problems. Additional research is needed to further assess the quality and type of sleep education provided in child psychiatry training programs. PMID- 29473878 TI - Alternative mRNA Splicing in the Pathogenesis of Obesity. AB - Alternative mRNA splicing is an important mechanism in expansion of proteome diversity by production of multiple protein isoforms. However, emerging evidence indicates that only a limited number of annotated protein isoforms by alternative splicing are detected, and the coding sequence of alternative splice variants usually is only slightly different from that of the canonical sequence. Nevertheless, mis-splicing is associated with a large array of human diseases. Previous reviews mainly focused on hereditary and somatic mutations in cis-acting RNA sequence elements and trans-acting splicing factors. The importance of environmental perturbations contributed to mis-splicing is not assessed. As significant changes in exon skipping and splicing factors expression levels are observed with diet-induced obesity, this review focuses on several well-known alternatively spliced metabolic factors and discusses recent advances in the regulation of the expressions of splice variants under the pathophysiological conditions of obesity. The potential of targeting the alternative mRNA mis splicing for obesity-associated diseases therapies will also be discussed. PMID- 29473881 TI - 3D Graphene-Nitrogen Doped Carbon Nanotubes Network Modified Electrode as Sensing Materials for the Determination of Urapidil. AB - In this work, a three dimensional (3D) graphene-nitrogen doped carbon nanotubes (G-NCNTs) network was successfully fabricated on the surface of a glassy carbon (GC) electrode using the pulse potential method (PPM) in a graphene oxide nitrogen doped carbon nanotubes (GO-NCNTs) dispersion. The morphological and characteristics of GO-NCNTs and G-NCNTs nanocomposites were investigated by atomic force microscopy (AFM), scanning electron microscopy (SEM), UV-vis spectroscopy, Raman spectroscopy, and electrochemical experiments. The 3DG-NCNTs network was applied as a new voltammetric material for the fabrication of an electrochemical platform for determination of urapidil. Systematic electrochemical tests demonstrate that the 3DG-NCNTs network modified GC electrode can effectively increase the response to the oxidation of urapidil. Under the optimum conditions, the electrochemical response was linear with urapidil concentrations in the range of 1.0 * 10-8~2.0 * 10-6 mol.L-1, while a low detection limit of 5.0 * 10-9 mol.L-1 was obtained for urapidil. Moreover, the proposed sensing platform exhibited good results for sensitivity, reproducibility, selectivity, and stability, which makes it very suitable for use as an ideal inexpensive and rapid analytical method applicable for complex drug matrices. PMID- 29473884 TI - Interest in Insects: The Role of Entomology in Environmental Education. AB - University-based outreach programs have a long history of offering environmental education programs to local schools, but often these lessons are not evaluated for their impact on teachers and students. The impact of these outreach efforts can be influenced by many things, but the instructional delivery method can affect how students are exposed to new topics or how confident teachers feel about incorporating new concepts into the classroom. A study was conducted with a series of university entomology outreach programs using insects as a vehicle for teaching environmental education. These programs were used to assess differences between three of the most common university-based outreach delivery methods (Scientist in the Classroom, Teacher Training Workshops, and Online Curriculum) for their effect on student interest and teacher self-efficacy. Surveys administered to 20 fifth grade classrooms found that the delivery method might not be as important as simply getting insects into activities. This study found that the lessons had a significant impact on student interest in environmental and entomological topics, regardless of treatment. All students found the lessons to be more interesting, valuable, and important over the course of the year. Treatment also did not influence teacher self-efficacy, as it remained high for all teachers. PMID- 29473882 TI - On the Metal Cofactor in the Tyrosinase Family. AB - The production of pigment in mammalian melanocytes requires the contribution of at least three melanogenic enzymes, tyrosinase and two other accessory enzymes called the tyrosinase-related proteins (Trp1 and Trp2), which regulate the type and amount of melanin. The last two proteins are paralogues to tyrosinase, and they appeared late in evolution by triplication of the tyrosinase gene. Tyrosinase is a copper-enzyme, and Trp2 is a zinc-enzyme. Trp1 has been more elusive, and the direct identification of its metal cofactor has never been achieved. However, due to its enzymatic activity and similarities with tyrosinase, it has been assumed as a copper-enzyme. Recently, recombinant human tyrosinase and Trp1 have been expressed in enough amounts to achieve for the first time their crystallization. Unexpectedly, it has been found that Trp1 contains a couple of Zn(II) at the active site. This review discusses data about the metal cofactor of tyrosinase and Trps. It points out differences in the studied models, and it proposes some possible points accounting for the apparent discrepancies currently appearing. Moreover, some proposals about the possible flexibility of the tyrosinase family to uptake copper or zinc are discussed. PMID- 29473885 TI - Physicochemical Properties and Chemical Stability of beta-Carotene Bilayer Emulsion Coated with Bovine Serum Albumin and Arabic Gum Compared to Monolayer Emulsions. AB - beta-carotene is a lipophilic micronutrient that is considered beneficial to human health. However, there are some limitations in utilizing beta-carotene in functional foods or dietary supplements currently because of its poor water dispersibility and chemical stability. A new type of beta-carotene bilayer emulsion delivery system was prepared by a layer-by-layer electrostatic deposition technique, for which were chosen bovine serum albumin (BSA) as the inner emulsifier and Arabic gum (GA) as the outer emulsifier. The physicochemical properties of bilayer emulsions were mainly characterized by droplet size distribution, zeta potential, rheological behavior, Creaming Index (CI), and encapsulation ratio of beta-carotene. Besides this, the effects of processing conditions (pH, thermal treatment, UV radiation, strong oxidant) and storage time on the chemical stability of bilayer emulsions were also evaluated. The bilayer emulsion had a small droplet size (221.27 +/- 5.17 nm) and distribution (PDI = 0.23 +/- 0.02), strong zeta potential (-30.37 +/- 0.71 mV), good rheological behavior (with the highest viscosity that could reduce the possibility of flocculation) and physical stability (CI = 0), high beta-carotene encapsulation ratio (94.35 +/- 0.71%), and low interfacial tension (40.81 +/- 0.86 mN/m). It also obtained better chemical stability under different environmental stresses when compared with monolayer emulsions studied, because it had a dense and thick bilayer structure. PMID- 29473883 TI - Emerging Nanomedicine Therapies to Counter the Rise of Methicillin-Resistant Staphylococcus aureus. AB - In a recent report, the World Health Organisation (WHO) classified antibiotic resistance as one of the greatest threats to global health, food security, and development. Methicillin-resistant Staphylococcus aureus (MRSA) remains at the core of this threat, with persistent and resilient strains detectable in up to 90% of S. aureus infections. Unfortunately, there is a lack of novel antibiotics reaching the clinic to address the significant morbidity and mortality that MRSA is responsible for. Recently, nanomedicine strategies have emerged as a promising therapy to combat the rise of MRSA. However, these approaches have been wide ranging in design, with few attempts to compare studies across scientific and clinical disciplines. This review seeks to reconcile this discrepancy in the literature, with specific focus on the mechanisms of MRSA infection and how they can be exploited by bioactive molecules that are delivered by nanomedicines, in addition to utilisation of the nanomaterials themselves as antibacterial agents. Finally, we discuss targeting MRSA biofilms using nano-patterning technologies and comment on future opportunities and challenges for MRSA treatment using nanomedicine. PMID- 29473886 TI - Antioxidation and Cytoprotection of Acteoside and Its Derivatives: Comparison and Mechanistic Chemistry. AB - The study tried to explore the role of sugar-residues and mechanisms of phenolic phenylpropanoid antioxidants. Acteoside, along with its apioside forsythoside B and rhamnoside poliumoside, were comparatively investigated using various antioxidant assays. In three electron-transfer (ET)-based assays (FRAP, CUPRAC, PTIO*-scavenging at pH 4.5), the relative antioxidant levels roughly ruled as: acteoside >forsythoside B > poliumoside. Such order was also observed in H+ transfer-involved PTIO*-scavenging assay at pH 7.4, and in three multiple-pathway involved radical-scavenging assays, i.e., ABTS+*-scavenging, DPPH*-scavenging, and *O2--scavenging. In UV-vis spectra, each of them displayed a red-shift at 335 >364 nm and two weak peaks (480 and 719 nm), when mixed with Fe2+; however, acteoside gave the weakest absorption. In Ultra-performance liquid chromatography coupled with electrospray ionization quadrupole time-of-flight tandem mass spectrometry (UPLC-ESI-Q-TOF-MS/MS) analysis, no radical-adduct-formation (RAF) peak was found. MTT assay revealed that poliumoside exhibited the highest viability of oxidative-stressed bone marrow-derived mesenchymal stem cells. In conclusion, acteoside, forsythoside B, and poliumoside may be involved in multiple-pathways to exert the antioxidant action, including ET, H+-transfer, or Fe2+-chelating, but not RAF. The ET and H+-transfer may be hindered by rhamnosyl and apiosyl moieties; however, the Fe2+-chelating potential can be enhanced by two sugar-residues (especially rhamnosyl moiety). The general effect of rhamnosyl and apiosyl moieties is to improve the antioxidant or cytoprotective effects. PMID- 29473887 TI - Characterization, Stability and Biological Activity In Vitro of Cathelicidin-BF 30 Loaded 4-Arm Star-Shaped PEG-PLGA Microspheres. AB - BF-30 is a single chain polypeptide of an N-segment with an alpha-helix from cathelicidin gene encoding, and it contains 30 amino acid residues, with a relative molecular mass and isoelectric point of 3637.54 and 11.79, respectively. Cathelicidin-BF-30 was entrapped in four-arm star-shaped poly(ethylene glycol-b dl-lactic acid-co-glycolic acid) block copolymers (4-arm-PEG-PLGA) by a double emulsion solvent-evaporation method. Three release phases of cathelicidin-BF 30loaded 4-arm-PEG-PLGA microspheres were observed, including an initial burst release phase, followed by a lag phase with minimal drug release and finally a secondary zero-order release phase. The delivery system released BF-30 over more than 15 days in vitro. Furthermore, the material for preparing the microspheres has good biocompatibility and biodegradability. Additionally, based on the drug resistance of food pathogenic bacteria, the antibacterial effects of BF-30 on Shigella dysenteriae CMCC 51105 (Sh. dysenteriae CMCC 51105), Salmonella typhi (S. typhi) and Staphylococcus aureus (S. aureus) as well as the stability of the in vitro release of the BF-30-loded microspheres were studied. The alpha-helix secondary structure and antibacterial activity of released BF-30 were retained and compared with native peptide. These BF-30 loaded microspheres presented <10% hemolysis and no toxicity for HEK293T cells even at the highest tested concentration (150 MUg/mL), indicating that they are hemocompatible and a promising delivery and protection system for BF-30 peptide. PMID- 29473889 TI - A Qualitative Investigation to Underpin the Development of an Electronic Tool to Assess Nutrition Literacy in Australians Adults. AB - Nutrition literacy is linked to health via its influence on dietary intake. There is a need for a tool to assess nutrition literacy in research and dietetic practice. We sought guidance from nutrition professionals on topic areas and features of an electronic nutrition literacy assessment tool for Australian adults. 28 experienced nutrition professionals engaged in a range of nutrition and dietetic work areas participated in six focus groups using a semi-structured interview schedule. Data were analysed using an inductive approach using NVivo 10 (QSR International, Pty Ltd., Doncaster, Australia, 2012). Key areas identified to assess nutrition literacy included specific nutrients versus foods, labels and packaging, construction of the diet, knowledge of the Australian Dietary Guidelines and Australian Guide to Healthy Eating, understanding of serve and portion sizes, ability to select healthier foods, and demographics such as belief systems and culture. Exploitation of electronic features to enhance visual and auditory displays, including interactive animations such as "drag and drop" and virtual reality situations, were discussed. This study provided insight into the most relevant topic areas and presentation format to assess the nutrition literacy of adult Australians. The visual, auditory, and interactive capacity of the available technology could enhance the assessment of nutrition literacy. PMID- 29473888 TI - Melatonin-Mediated Development of Ovine Cumulus Cells, Perhaps by Regulation of DNA Methylation. AB - Cumulus cells of pre-pubertal domestic animals are dysfunctional, perhaps due to age-specific epigenetic events. This study was designed to determine effects of melatonin treatment of donors on methylation modification of pre-pubertal cumulus cells. Cumulus cells from germinal vesicle stage cumulus oocyte complexes (COCs) were collected from eighteen lambs which were randomly divided into control group (C) and melatonin group given an 18 mg melatonin implant subcutaneous (M). Compared to the C group, the M group had higher concentrations of melatonin in plasma and follicular fluid (p < 0.05), greater superovulation, a higher proportion of fully expanded COCs, and a lower proportion of apoptotic cumulus cells (p < 0.05). Real-time PCR results showed that melatonin up-regulated expression of genes MT1, Bcl2, DNMT1, DNMT3a and DNMT3b, but down-regulated expression of genes p53, Caspase 3 and Bax (p < 0.05). Furthermore, melatonin increased FI of FITC (global methylation level) on cumulus cells (p < 0.05). To understand the regulation mechanism, the DNMTs promoter methylation sequence were analyzed. Compared to the C group, although there was less methylation at two CpG sites of DNMT1 (p < 0.05) and higher methylation at two CpG sites of DNMT3a (p < 0.05), there were no significant differences in methylation of the detected DNMT1 and DNMT3a promoter regions. However, there were lower methylation levels at five CpG sites of DNMT3b, which decreased methylation of detected DNMT3b promoter region on M group (p < 0.05). In conclusion, alterations of methylation regulated by melatonin may mediate development of cumulus cells in lambs. PMID- 29473890 TI - Printed Graphene Derivative Circuits as Passive Electrical Filters. AB - The objective of this study is to inkjet print resistor-capacitor (RC) low pass electrical filters, using a novel water-based cellulose graphene ink, and compare the voltage-frequency and transient behavior to equivalent circuits constructed from discrete passive components. The synthesized non-toxic graphene carboxymethyl cellulose (G-CMC) ink is deposited on mechanically flexible polyimide substrates using a customized printer that dispenses functionalized aqueous solutions. The design of the printed first-order and second-order low pass RC filters incorporate resistive traces and interdigitated capacitors. Low pass filter characteristics, such as time constant, cut-off frequency and roll off rate, are determined for comparative analysis. Experiments demonstrate that for low frequency applications (<100 kHz) the printed graphene derivative circuits performed as well as the circuits constructed from discrete resistors and capacitors for both low pass filter and RC integrator applications. The impact of mechanical stress due to bending on the electrical performance of the flexible printed circuits is also investigated. PMID- 29473891 TI - The Preparation, Characterization, Mechanical and Antibacterial Properties of GO ZnO Nanocomposites with a Poly(l-lactide)-Modified Surface. AB - Graphene oxide (GO) was employed for the preparation of GO-zinc oxide (ZnO). The hydroxyl group on the surface was exploited to trigger the l-lactide ring-opening polymerization. A composite material with poly(l-lactide) (PLLA) chains grafted to the GO-ZnO surface, GO-ZnO-PLLA, was prepared. The results demonstrated that the employed method allowed one-step, rapid grafting of PLLA to the GO-ZnO surface. The chemical structure of the GO surface was altered by improved dispersion of GO-ZnO in organic solvents, thus enhancing the GO-ZnO dispersion in the PLLA matrix and the interface bonding with PLLA. Subsequently, composite films, GO-ZnO-PLLA and GO-ZnO-PLLA/PLLA, were prepared. The changes in interface properties and mechanical properties were studied. Furthermore, the antibacterial performance of nano-ZnO was investigated. PMID- 29473892 TI - Gender Differences in the Association between Dietary Pattern and the Incidence of Hypertension in Middle-Aged and Older Adults. AB - We examined gender differences in the association between dietary patterns and the risk of hypertension, using the Korean Genome and Epidemiology Study data. A total of 5090 participants (2457 men and 2633 women) aged 40-69 years without hypertension at baseline were selected. Dietary patterns were obtained using factor analysis based on 26 food groups, evaluated by a validated semi quantitative food frequency questionnaire at baseline. Hypertension was defined as systolic blood pressure >= 140 mmHg or diastolic blood pressure >= 90 mmHg, or the use of antihypertensive medication using the biennial measurements. Multivariate Cox proportional hazards models were used to examine the associations between dietary patterns and hypertension. Four dietary patterns were extracted: coffee, fat, and sweets; prudent; whole grains and legumes; and traditional (men)/Western (women). Women in the highest tertile of the whole grains and legumes pattern scores showed a lower risk of incident hypertension compared with those in the lowest tertile (hazard ratio = 0.77, 95% confidence interval = 0.59-1.00, p-trend = 0.048). Other dietary patterns were not associated with hypertension in either men or women. A diet rich in whole grains and legumes is inversely associated with the risk of hypertension in Korean women, suggesting a gender difference in the association between diet and hypertension. PMID- 29473894 TI - Health- and Taste-Related Attitudes Associated with Dietary Patterns in a Representative Sample of Polish Girls and Young Women: A Cross-Sectional Study (GEBaHealth Project). AB - Attitudes can be predictors of certain health-related behaviours. The attitudes of young females towards health and taste have not been yet fully examined and their associations with dietary behaviours remain unclear. The aim of the study was to investigate if attitudes are associated with dietary patterns in a representative sample of Polish girls. The study population consisted of 1107 girls, aged 13-21 and living in Poland. Attitudes were assessed using the Health and Taste Attitudes Scale (HTAS) and categorised as negative, neutral or positive. Dietary data was obtained using a Food Frequency Questionnaire. Dietary patterns (DPs), derived previously with a Principal Component Analysis (PCA), were 'Traditional Polish', 'Fruit and vegetables', 'Fast food and sweets' and 'Dairy and fats'. The associations between attitudes and DPs were assessed using Spearman's correlation coefficients and logistic regression. The reference group were girls with neutral attitudes. Odds ratios (ORs) were adjusted for age, socioeconomic status (SES), and body mass index (BMI). The correlations between attitudes and DPs ranged from -0.28 for attitudes towards health and 'Fast food and sweets' and 'Traditional Polish' DPs to 0.33 for attitudes towards health and the 'Fruit and vegetables' DP (p < 0.05). In the logistic regression analysis, the strongest associations within health-related HTAS subscales were observed between negative attitudes towards natural products and the 'Fast food and sweets' DP (OR: 10.93; 95% CI: 3.32-36.01) and between positive attitudes towards health and the 'Fruit and vegetables' DP (OR: 5.10; 3.11-8.37). The strongest associations within taste-related HTAS subscales were observed between positive attitudes towards craving for sweet foods and the 'Traditional Polish' DP (OR: 1.93; 1.43-2.61) and between positive attitudes towards using food as a reward and the 'Dairy and fats' DP (OR: 2.08; 1.22-3.55) as well as the 'Fast food and sweets' DP (OR: 2.07; 1.14-3.74). Positive attitudes towards health were associated with a pro-healthy dietary pattern characterised by the consumption of fruit and vegetables, while negative attitudes towards natural products as well as a strong craving for sweets and using food as a reward were associated with less healthy dietary patterns. To improve the dietary habits of girls and young women, positive attitudes towards health should be strengthened and supported by emphasizing the sensory values of pro-healthy foods. PMID- 29473895 TI - The Gene-Centric Content Management System and Its Application for Cognitive Proteomics. AB - The Human Proteome Project is moving into the next phase of creating and/or reconsidering the functional annotations of proteins using the chromosome-centric paradigm. This challenge cannot be solved exclusively using automated means, but rather requires human intelligence for interpreting the combined data. To foster the integration between human cognition and post-genome array a number of specific tools were recently developed, among them CAPER, GenomewidePDB, and The Proteome Browser (TPB). For the purpose of tackling the task of protein functional annotating the Gene-Centric Content Management System (GenoCMS) was expanded with new features. The goal was to enable bioinformaticans to develop self-made applications and to position these applets within the generalized informational canvas supported by GenoCMS. We report the results of GenoCMS enabled integration of the concordant informational flows in the chromosome centric framework of the human chromosome 18 project. The workflow described in the article can be scaled to other human chromosomes, and also supplemented with new tracks created by the user. The GenoCMS is an example of a project-oriented informational system, which are important for public data sharing. PMID- 29473893 TI - Restoration of Muscle Glycogen and Functional Capacity: Role of Post-Exercise Carbohydrate and Protein Co-Ingestion. AB - The importance of post-exercise recovery nutrition has been well described in recent years, leading to its incorporation as an integral part of training regimes in both athletes and active individuals. Muscle glycogen depletion during an initial prolonged exercise bout is a main factor in the onset of fatigue and so the replenishment of glycogen stores may be important for recovery of functional capacity. Nevertheless, nutritional considerations for optimal short term (3-6 h) recovery remain incompletely elucidated, particularly surrounding the precise amount of specific types of nutrients required. Current nutritional guidelines to maximise muscle glycogen availability within limited recovery are provided under the assumption that similar fatigue mechanisms (i.e., muscle glycogen depletion) are involved during a repeated exercise bout. Indeed, recent data support the notion that muscle glycogen availability is a determinant of subsequent endurance capacity following limited recovery. Thus, carbohydrate ingestion can be utilised to influence the restoration of endurance capacity following exhaustive exercise. One strategy with the potential to accelerate muscle glycogen resynthesis and/or functional capacity beyond merely ingesting adequate carbohydrate is the co-ingestion of added protein. While numerous studies have been instigated, a consensus that is related to the influence of carbohydrate-protein ingestion in maximising muscle glycogen during short-term recovery and repeated exercise capacity has not been established. When considered collectively, carbohydrate intake during limited recovery appears to primarily determine muscle glycogen resynthesis and repeated exercise capacity. Thus, when the goal is to optimise repeated exercise capacity following short-term recovery, ingesting carbohydrate at an amount of >=1.2 g kg body mass-1.h-1 can maximise muscle glycogen repletion. The addition of protein to carbohydrate during post exercise recovery may be beneficial under circumstances when carbohydrate ingestion is sub-optimal (<=0.8 g kg body mass-1.h-1) for effective restoration of muscle glycogen and repeated exercise capacity. PMID- 29473896 TI - Congenital Toxoplasmosis: A Plea for a Neglected Disease. AB - Maternal infection by Toxoplasma gondii during pregnancy may have serious consequences for the fetus, ranging from miscarriage, central nervous system involvement, retinochoroiditis, or subclinical infection at birth with a risk of late onset of ocular diseases. As infection in pregnant women is usually symptomless, the diagnosis relies only on serological tests. Some countries like France and Austria have organized a regular serological testing of pregnant women, some others have no prenatal program of surveillance. Reasons for these discrepant attitudes are many and debatable. Among them are the efficacy of antenatal treatment and cost-effectiveness of such a program. A significant body of data demonstrated that rapid onset of treatment after maternal infection reduces the risk and severity of fetal infection. Recent cost-effectiveness studies support regular screening. This lack of consensus put both pregnant women and care providers in a difficult situation. Another reason why congenital toxoplasmosis is disregarded in some countries is the lack of precise information about its impact on the population. Precise estimations on the burden of the disease can be achieved by systematic screening that will avoid bias or underreporting of cases and provide a clear view of its outcome. PMID- 29473897 TI - Design, Optimization and Characterization of a Transfersomal Gel Using Miconazole Nitrate for the Treatment of Candida Skin Infections. AB - Miconazole nitrate (MIC) is an antifungal drug used for treatment of superficial fungal infections. However, it has low skin permeability. Hence, the objective of this study was to prepare miconazole nitrate using Transfersomes to overcome the barrier function of the skin. MIC Transfersomes were prepared using a thin lipid film hydration technique. The prepared Transfersomes were evaluated with respect to entrapment efficiency (EE%), particle size, and quantity of in vitro drug released to obtain an optimized formulation. The optimized formulation of MIC Transfersomes was incorporated into a Carbapol 934 gel base which was evaluated in comparison with a marketed product (Daktarin(r) cream 2%) for drug content, pH, spreadability, viscosity, in vitro permeation, and in vitro and in vivo antifungal activity. The prepared MIC Transfersomes had a high EE% ranging from (67.98 +/- 0.66%) to (91.47 +/- 1.85%), with small particle sizes ranging from (63.5 +/- 0.604 nm) to (84.5 +/- 0.684 nm). The in vitro release study suggested that there was an inverse relationship between EE% and in vitro release. The kinetic analysis of all release profiles was found to follow Higuchi's diffusion model. All independent variables had a significant effect on the dependent variables (p-values < 0.05). The prepared MIC transfersomal gel showed higher antifungal activity than Daktarin(r) cream 2%. Therefore, miconazole nitrate in the form of Transfersomes has the ability to penetrate the skin, overcoming the stratum corneum barrier. PMID- 29473898 TI - Australia's Ongoing Legacy of Asbestos: Significant Challenges Remain Even after the Complete Banning of Asbestos Almost Fifteen Years Ago. AB - The most effective way of reducing the global burden of asbestos-related diseases is through the implementation of asbestos bans and minimising occupational and non-occupational exposure to respirable asbestos fibres. Australia's asbestos consumption peaked in the 1970s with Australia widely thought to have had among the highest per-capita asbestos consumption level of any country. Australia's discontinuation of all forms of asbestos and asbestos-containing products and materials did not occur at a single point of time. Crocidolite consumption ceased in the late 1960s, followed by amosite consumption stopping in the mid 1980s. Despite significant government reports being published in 1990 and 1999, it was not until the end of 2003 that a complete ban on all forms of asbestos (crocidolite, amosite, and chrysotile) was introduced in Australia. The sustained efforts of trade unions and non-governmental organisations were essential in forcing the Australian government to finally implement the 2003 asbestos ban. Trade unions and non-government organisations continue to play a key role today in monitoring the government's response to Australian asbestos-related disease epidemic. There are significant challenges that remain in Australia, despite a complete asbestos ban being implemented almost fifteen years ago. The Australian epidemic of asbestos-related disease has only now reached its peak. A total of 16,679 people were newly diagnosed with malignant mesothelioma between 1982 and 2016, with 84% of cases occurring in men. There has been a stabilisation of the age-standardised malignant mesothelioma incidence rate in the last 10 years. In 2016, the incidence rate per 100,000 was 2.5 using the Australian standard population and 1.3 using the Segi world standard population. Despite Australia's complete asbestos ban being in place since 2003, public health efforts must continue to focus on preventing the devastating effects of avoidable asbestos related diseases, including occupational and non-occupational groups who are potentially at risk from exposure to respirable asbestos fibres. PMID- 29473900 TI - Qualification of Food Intake by the Roma Population in the Region of South Bohemia. AB - The article presents the results of a correlation study, aimed at quantifying the food intake of the Roma population in the South Bohemian Region. To achieve the goal, we applied the method of one-day dietary recall and frequency food analysis (non-standardized). The quantification was carried out by analysis in the Nutridan program. The study involved 302 Roma persons and 298 persons in the control group. Both groups had the same representation of males and females (50:50). The age categories of both sets differed; the average age of the Roma was lower (39.2 years) (p < 0.001). The probands from the Roma population were chosen with the help of the snowball method through known respondents. The statistical analysis shows differences in nutritional estimate between the Roma population and the control sample. The Roma differ in their energy intake. Both groups showed lower intake of sugars, below 50% total energy intake (TEI) and higher intake of fats, above 30% TEI. The respondents from both groups consume little fruits and vegetables, which may be connected with their low dietary fiber intake. In addition to the differences in the nutritional estimates, we recorded statistically significant differences in body mass index (BMI; p < 0.001), in age (p < 0.001), regular alimentation (p = 0) and demanding physical activities (p = 0). In spite of the fact our groups differed in age (the Roma are younger), it can be assumed that the obesity of the Roma may be caused by unbalanced alimentation and lack of physical activities.

AB - Despite numerous efforts to identify the molecular and cellular effectors of the adaptive immunity that induce a long-lasting immunity against dengue or Zika virus infection, the specific mechanisms underlying such protective immunity remain largely unknown. One of the major challenges lies in the high level of dengue virus (DENV) seroprevalence in areas where Zika virus (ZIKV) is circulating. In the context of such a pre-existing DENV immunity that can exacerbate ZIKV infection and disease, and given the lack of appropriate treatment for ZIKV infection, there is an urgent need to develop an efficient vaccine against DENV and ZIKV. Notably, whereas several ZIKV vaccine candidates are currently in clinical trials, all these vaccine candidates have been designed to induce neutralizing antibodies as the primary mechanism of immune protection. Given the difficulty to elicit simultaneously high levels of neutralizing antibodies against the different DENV serotypes, and the potential impact of pre existing subneutralizing antibodies induced upon DENV infection or vaccination on ZIKV infection and disease, additional or alternative strategies to enhance vaccine efficacy, through T cell immunity, are now being considered. In this review, we summarize recent discoveries about cross-reactive B and T cell responses against DENV and ZIKV and propose guidelines for the development of safe and efficient T cell vaccines targeting both viruses. PMID- 29473901 TI - Comparative Analysis of Major Mosquito Vectors Response to Seed-Derived Essential Oil and Seed Pod-Derived Extract from Acacia nilotica. AB - Botanical metabolites are increasingly realized as potential replacements to chemical insecticides. In the present study, Acacia nilotica seed essential oil and seed pod solvent extracts were tested for bioefficacy against three important types of mosquitoes. Mortality was recorded 24 h post-treatment, while smoke toxicity of adult mosquitoes was recorded at 10 min intervals for 40 min. Seed pod powder was extracted with different solvents and hydrodistilled seed oil chemical constituents were determined by using Gas chromatography mass spectroscopy (GC-MS) -. Larvicidal and adulticidal efficacy of seed hydrodistilled essential oil and solvent extracts were tested against larval and adult mosquitoes. The seed hydrodistilled oil provided strong larvicidal activity against Anopheles stephensi, (LC50 (lethal concentration that kills 50% of the exposed larvae) = 5.239, LC90 (lethal concentration that kills 90% of the exposed larvae) = 9.713 mg/L); Aedes aegypti, (LC50 = 3.174, LC90 = 11.739 mg/L); and Culex quinquefasciatus, (LC50 = 4.112, LC90 = 12.325 mg/L). Smoke toxicities were 82% in Cx. quinquefasciatus, 90% in Ae. aegypti, and 80% mortality in An. stephensi adults, whereas 100% mortality was recorded for commercial mosquito coil. The GC-MS profile of seed essential oil from A. nilotica showed the presence of hexadecane (18.440%) and heptacosane (15.914%), which are the main and active compounds, and which may be involved in insecticidal activity. Overall findings suggest that the seed oil showed strong mosquitocidal activity against mosquito vectors and therefore may provide an ecofriendly replacement to chemical insecticides.

AB - Since the origin of the Modern Movement, there has been a basic commitment to improving housing conditions and the well-being of occupants, especially given the prediction that 2/3 of humanity will reside in cities by 2050. Moreover, a compact model of the city with tall buildings and urban densification at this scale will be generated. Continuous constructive and technological advances have developed solid foundations on safety, energy efficiency, habitability, and sustainability in housing design. However, studies on improving the quality of life in these areas continue to be a challenge for architects and engineers. This paper seeks to contribute health-related information to the study of residential design, specifically the influence of the geomagnetic field on its occupants. After compiling information on the effects of geomagnetic fields from different medical studies over 23 years, a case study of a 16-story high-rise building is presented, with the goal of proposing architectural design recommendations for long-term occupation in the same place. The purpose of the present work is three fold: first, to characterize the geomagnetic field variability of buildings; second, to identify the causes and possible related mechanisms; and third, to define architectural criteria on the arrangement of uses and constructive elements for housing. PMID- 29473904 TI - Sinus Bradycardia in Carriers of the SCN5A-1795insD Mutation: Unraveling the Mechanism through Computer Simulations. AB - The SCN5A gene encodes the pore-forming alpha-subunit of the ion channel that carries the cardiac fast sodium current (INa). The 1795insD mutation in SCN5A causes sinus bradycardia, with a mean heart rate of 70 beats/min in mutation carriers vs. 77 beats/min in non-carriers from the same family (lowest heart rate 41 vs. 47 beats/min). To unravel the underlying mechanism, we incorporated the mutation-induced changes in INa into a recently developed comprehensive computational model of a single human sinoatrial node cell (Fabbri-Severi model). The 1795insD mutation reduced the beating rate of the model cell from 74 to 69 beats/min (from 49 to 43 beats/min in the simulated presence of 20 nmol/L acetylcholine). The mutation-induced persistent INa per se resulted in a substantial increase in beating rate. This gain-of-function effect was almost completely counteracted by the loss-of-function effect of the reduction in INa conductance. The further loss-of-function effect of the shifts in steady-state activation and inactivation resulted in an overall loss-of-function effect of the 1795insD mutation. We conclude that the experimentally identified mutation induced changes in INa can explain the clinically observed sinus bradycardia. Furthermore, we conclude that the Fabbri-Severi model may prove a useful tool in understanding cardiac pacemaker activity in humans. PMID- 29473905 TI - The In Vitro Effects of Enzymatic Digested Gliadin on the Functionality of the Autophagy Process. AB - Gliadin, the alcohol-soluble protein fraction of wheat, contains the factor toxic for celiac disease (CD), and its toxicity is not reduced by digestion with gastro pancreatic enzymes. Importantly, it is proved that an innate immunity to gliadin plays a key role in the development of CD. The immune response induces epithelial stress and reprograms intraepithelial lymphocytes into natural killer (NK)-like cells, leading to enterocyte apoptosis and an increase in epithelium permeability. In this contribution, we have reported that in Caco-2 cells the administration of enzymatically digested gliadin (PT-gliadin) reduced significantly the expression of the autophagy-related marker LC3-II. Furthermore, electron and fluorescent microscope analysis suggested a compromised functionality of the autophagosome apparatus. The rescue of the dysregulated autophagy process, along with a reduction of PT-gliadin toxicity, was obtained with a starvation induction protocol and by 3-methyladenine administration, while rapamycin, a well-known autophagy inducer, did not produce a significant improvement in the clearance of extra- and intra-cellular fluorescent PT-gliadin amount. Altogether, our results highlighted the possible contribution of the autophagy process in the degradation and in the reduction of extra-cellular release of gliadin peptides and suggest novel molecular targets to counteract gliadin-induced toxicity in CD. PMID- 29473906 TI - Risk Factors of Extended-Spectrum beta-Lactamase Producing Enterobacteriaceae Occurrence in Farms in Reunion, Madagascar and Mayotte Islands, 2016-2017. AB - In South Western Indian ocean (IO), Extended-Spectrum beta-Lactamase producing Enterobacteriaceae (ESBL-E) are a main public health issue. In livestock, ESBL-E burden was unknown. The aim of this study was estimating the prevalence of ESBL-E on commercial farms in Reunion, Mayotte and Madagascar and genes involved. Secondly, risk factors of ESBL-E occurrence in broiler, beef cattle and pig farms were explored. In 2016-2017, commercial farms were sampled using boot swabs and samples stored at 4 degrees C before microbiological analysis for phenotypical ESBL-E and gene characterization. A dichotomous questionnaire was performed. Prevalences observed in all production types and territories were high, except for beef cattle in Reunion, which differed significantly. The most common ESBL gene was blaCTX-M-1. Generalized linear models explaining ESBL-E occurrence varied between livestock production sectors and allowed identifying main protective (e.g., water quality control and detergent use for cleaning) and risk factors (e.g., recent antibiotic use, other farmers visiting the exploitation, pet presence). This study is the first to explore tools for antibiotic resistance management in IO farms. It provides interesting hypothesis to explore about antibiotic use in IO territories and ESBL-E transmission between pig, beef cattle and humans in Madagascar. PMID- 29473903 TI - The Role of Culex pipiens L. (Diptera: Culicidae) in Virus Transmission in Europe. AB - Over the past three decades, a range of mosquito-borne viruses that threaten public and veterinary health have emerged or re-emerged in Europe. Mosquito surveillance activities have highlighted the Culex pipiens species complex as being critical for the maintenance of a number of these viruses. This species complex contains morphologically similar forms that exhibit variation in phenotypes that can influence the probability of virus transmission. Critical amongst these is the choice of host on which to feed, with different forms showing different feeding preferences. This influences the ability of the mosquito to vector viruses and facilitate transmission of viruses to humans and domestic animals. Biases towards blood-feeding on avian or mammalian hosts have been demonstrated for different Cx. pipiens ecoforms and emerging evidence of hybrid populations across Europe adds another level of complexity to virus transmission. A range of molecular methods based on DNA have been developed to enable discrimination between morphologically indistinguishable forms, although this remains an active area of research. This review provides a comprehensive overview of developments in the understanding of the ecology, behaviour and genetics of Cx. pipiens in Europe, and how this influences arbovirus transmission. PMID- 29473909 TI - Assessment of Pressure Sources and Water Body Resilience: An Integrated Approach for Action Planning in a Polluted River Basin. AB - The present study develops an integrated methodology combining the results of the water-quality classification, according to the Water Framework Directive 2000/60/EC-WFD, with those of a mathematical integrity model. It is able to analyse the potential anthropogenic impacts on the receiving water body and to help municipal decision-makers when selecting short/medium/long-term strategic mitigation actions to be performed in a territory. Among the most important causes of water-quality degradation in a river, the focus is placed on pollutants from urban wastewater. In particular, the proposed approach evaluates the efficiency and the accurate localisation of treatment plants in a basin, as well as the capacity of its river to bear the residual pollution loads after the treatment phase. The methodology is applied to a sample catchment area, located in northern Italy, where water quality is strongly affected by high population density and by the presence of agricultural and industrial activities. Nearly 10 years of water-quality data collected through official monitoring are considered for the implementation of the system. The sample basin shows different real and potential pollution conditions, according to the resilience of the river and surroundings, together with the point and diffuse pressure sources acting on the receiving body. PMID- 29473910 TI - A Method for Dynamically Selecting the Best Frequency Hopping Technique in Industrial Wireless Sensor Network Applications. AB - Industrial wireless applications often share the communication channel with other wireless technologies and communication protocols. This coexistence produces interferences and transmission errors which require appropriate mechanisms to manage retransmissions. Nevertheless, these mechanisms increase the network latency and overhead due to the retransmissions. Thus, the loss of data packets and the measures to handle them produce an undesirable drop in the QoS and hinder the overall robustness and energy efficiency of the network. Interference avoidance mechanisms, such as frequency hopping techniques, reduce the need for retransmissions due to interferences but they are often tailored to specific scenarios and are not easily adapted to other use cases. On the other hand, the total absence of interference avoidance mechanisms introduces a security risk because the communication channel may be intentionally attacked and interfered with to hinder or totally block it. In this paper we propose a method for supporting the design of communication solutions under dynamic channel interference conditions and we implement dynamic management policies for frequency hopping technique and channel selection at runtime. The method considers several standard frequency hopping techniques and quality metrics, and the quality and status of the available frequency channels to propose the best combined solution to minimize the side effects of interferences. A simulation tool has been developed and used in this work to validate the method. PMID- 29473907 TI - Pharmacological Inhibition of Protein Kinase C Reduces West Nile Virus Replication. AB - Flaviviruses are relevant animal and human pathogens that include West Nile virus (WNV), Japanese encephalitis virus, dengue virus, or Zika virus, among others. Currently, no licensed therapy is available to fight flaviviral infections. Protein kinases C (PKCs) constitute a family of multifunctional lipid-dependent isoenzymes that regulate a wide variety of cellular processes (apoptosis, differentiation, proliferation, cellular transformation, motility, adhesion, etc.) being currently considered at the front line of drug development for the treatment of diverse human disorders. PKCs have also been implicated in different steps during viral replication; however, nowadays, results regarding their role in flavivirus replication are controversial. Here we demonstrate that calphostin C and chelerythrine, two broad-PKC inhibitors that target conventional, novel and atypical PKCs, significantly inhibit WNV multiplication in cell culture without affecting cell viability. A reduction of viral yields was observed in treated cells when compared with mock-treated cells. Likewise, immunofluorescence detection of viral enveloped E protein was reduced in treated cells, as was the amount of viral RNA released to the supernatant, mainly in those treated with chelerythrine. On the other hand, two PKC inhibitors specific for conventional and novel isoforms (staurosporine and enzastaurine) did not show any significant effect in WNV multiplication. These results suggested that PKCs, more probably atypical PKCs, are likely involved in WNV multiplication, although both broad spectrum tested drugs seem to act through different mechanisms, and point to them as potential antiviral candidates for WNV, as well as for other related flaviviruses. PMID- 29473908 TI - l-Carnitine Supplementation in Older Women. A Pilot Study on Aging Skeletal Muscle Mass and Function. AB - Skeletal muscle wasting, associated with aging, may be regulated by the inflammatory cytokines as well as by insulin-like growth factor 1 (IGF-1). l carnitine possesses anti-inflammatory properties and increases plasma IGF-1 concentration, leading to the regulation of the genes responsible for protein catabolism and anabolism. The purpose of the present study was to evaluate the effect of a 24-week l-carnitine supplementation on serum inflammatory markers, IGF-1, body composition and skeletal muscle strength in healthy human subjects over 65 years of age. Women between 65 and 70 years of age were supplemented for 24 weeks with either 1500 mg l-carnitine-l-tartrate or an isonitrogenous placebo per day in a double-blind fashion. Before and after the supplementation protocol, body mass and composition, as well as knee extensor and flexor muscle strength were determined. In the blood samples, free carnitine, interleukin-6, tumor necrosis factor-alpha, C-reactive protein and IGF-1 were determined. A marked increase in free plasma carnitine concentration was observed due to l-carnitine supplementation. No substantial changes in other parameters were noted. In the current study, supplementation for 24 weeks affected neither the skeletal muscle strength nor circulating markers in healthy women over 65 years of age. Positive and negative aspects of l-carnitine supplementation need to be clarified. PMID- 29473911 TI - Methionine-Capped Gold Nanoclusters as a Fluorescence-Enhanced Probe for Cadmium(II) Sensing. AB - Gold nanoclusters (Au NCs) have been considered as novel heavy metal ions sensors due to their ultrafine size, photo-stability and excellent fluorescent properties. In this study, a green and facile method was developed for the preparation of fluorescent water-soluble gold nanoclusters with methionine as a stabilizer. The nanoclusters emit orange fluorescence with excitation/emission peaks at 420/565 nm and a quantum yield of about 1.46%. The fluorescence of the Au NCs is selectively and sensitively enhanced by addition of Cd(II) ions attributed to the Cd(II) ion-induced aggregation of nanoclusters. This finding was further used to design a fluorometric method for the determination of Cd(II) ions, which had a linear response in the concentration range from 50 nM to 35 MUM and a detection limit of 12.25 nM. The practicality of the nanoprobe was validated in various environmental water samples and milk powder samples, with a fairly satisfactory recovery percent. PMID- 29473912 TI - Application of Improved 5th-Cubature Kalman Filter in Initial Strapdown Inertial Navigation System Alignment for Large Misalignment Angles. AB - In view of the fact the accuracy of the third-degree Cubature Kalman Filter (CKF) used for initial alignment under large misalignment angle conditions is insufficient, an improved fifth-degree CKF algorithm is proposed in this paper. In order to make full use of the innovation on filtering, the innovation covariance matrix is calculated recursively by an innovative sequence with an exponent fading factor. Then a new adaptive error covariance matrix scaling algorithm is proposed. The Singular Value Decomposition (SVD) method is used for improving the numerical stability of the fifth-degree CKF in this paper. In order to avoid the overshoot caused by excessive scaling of error covariance matrix during the convergence stage, the scaling scheme is terminated when the gradient of azimuth reaches the maximum. The experimental results show that the improved algorithm has better alignment accuracy with large misalignment angles than the traditional algorithm. PMID- 29473913 TI - Establishment of the Volatile Signature of Wine-Based Aromatic Vinegars Subjected to Maceration. AB - The flavoring of vinegars with aromatic fruits and medicinal herbs is a practice with increasing trend mostly in countries with oenological tradition, resulting in a product of improved quality and consumer attractiveness. This study was directed towards the evaluation of the impact of the maceration process on the volatile signature of wine-based aromatic vinegars (WBAVs). The evaluation was performed using solid phase microextraction (SPME) combined with gas chromatography combined with mass spectrometry (GC-MS). Experimental parameters influencing headspace solid (HS)-SPME extraction efficiency, were optimized using an univariate experimental design. The best results were achieved using a polydimethylsiloxane (PDMS) fiber, 10 mL of vinegar sample, at 50 degrees C for 30 min of extraction. This way One hundred and three volatile organic compounds (VOCs), belonging to different chemical families including ethyl esters (37), higher alcohols (20), fatty acids (10), terpenoids (23), carbonyl compounds (six), lactones (five) and volatile phenols (two), were identified in wine vinegar (control) and WBAV. As far as we know, 34 of these VOCs are reported for the first time in macerated vinegars. Higher alcohols and lactones are the major chemical families in WBAV macerated with apple, whereas terpenoids are predominant in WBAV macerated with banana. The obtained data represent a suitable tool to guarantee the authenticity and genuineness of WBAV, as well as to promote the production of WBAV with improved sensorial and organoleptic properties. To the best of our knowledge, there are no reported studies dealing with the volatile signature of WBAV enriched with banana, passion fruit, apple and pennyroyal. PMID- 29473914 TI - Fe3O4 Nanoparticles in Targeted Drug/Gene Delivery Systems. AB - Fe3O4 nanoparticles (NPs), the most traditional magnetic nanoparticles, have received a great deal of attention in the biomedical field, especially for targeted drug/gene delivery systems, due to their outstanding magnetism, biocompatibility, lower toxicity, biodegradability, and other features. Naked Fe3O4 NPs are easy to aggregate and oxidize, and thus are often made with various coatings to realize superior properties for targeted drug/gene delivery. In this review, we first list the three commonly utilized synthesis methods of Fe3O4 NPs, and their advantages and disadvantages. In the second part, we describe coating materials that exhibit noticeable features that allow functionalization of Fe3O4 NPs and summarize their methods of drug targeting/gene delivery. Then our efforts will be devoted to the research status and progress of several different functionalized Fe3O4 NP delivery systems loaded with chemotherapeutic agents, and we present targeted gene transitive carriers in detail. In the following section, we illuminate the most effective treatment systems of the combined drug and gene therapy. Finally, we propose opportunities and challenges of the clinical transformation of Fe3O4 NPs targeting drug/gene delivery systems. PMID- 29473917 TI - Enhanced Humidity Sensitivity with Silicon Nanopillar Array by UV Light. AB - The sensitivity of silicon nanopillar array for relative humidity (RH) with UV illumination was investigated in this work. The silicon nanopillar array was prepared by nanosphere lithography. Electrical measurements were performed on its sensing performance with and without UV irradiation. It was found that UV light improved the humidity sensitivity with different UV light wavelengths and power. The sensor response and recovery time were reduced. Furthermore, the turn-on threshold voltage and the operating voltage both decreased. These sensing characteristics can mainly be attributed to the electron-hole pairs generated by UV light. These electron-hole pairs promote the adsorption and desorption processes. The results indicate that silicon nanopillar array materials with UV irradiation might be competitive as novel sensing materials for fabricating humidity sensors with high performances. PMID- 29473916 TI - Effects of Diets Differing in Composition of 18-C Fatty Acids on Adipose Tissue Thermogenic Gene Expression in Mice Fed High-Fat Diets. AB - Dietary fatty acids play important roles in the regulation of fat accumulation or metabolic phenotype of adipocytes, either as brown or beige fat. However, a systematic comparison of effects of diets with different composition of 18-C fatty acids on browning/beiging phenotype has not been done. In this study, we compared the effects of different dietary fats, rich in specific 18-carbon fatty acids, on thermogenesis and lipid metabolism. Male C57BL/6 mice were fed a control diet containing 5.6% kcal fat from lard and 4.4% kcal fat from soybean oil (CON) or high-fat diets (HFD) containing 25% kcal from lard and 20% kcal fat from shea butter (stearic acid-rich fat; SHB), olive oil (oleic acid-rich oil; OO), safflower oil (linoleic acid-rich oil; SFO), or soybean oil (mixed oleic, linoleic, and alpha-linolenic acids; SBO) ad libitum for 12 weeks, with or without a terminal 4-h norepinephrine (NE) treatment. When compared to SHB, feeding OO, SFO, and SBO resulted in lower body weight gain. The OO fed group had the highest thermogenesis level, which resulted in lower body fat accumulation and improved glucose and lipid metabolism. Feeding SFO downregulated expression of lipid oxidation-related genes and upregulated expression of lipogenic genes, perhaps due to its high n-6:n-3 ratio. In general, HFD-feeding downregulated Ucp1 expression in both subcutaneous and epididymal white adipose tissue, and suppressed NE-induced Pgc1a expression in brown adipose tissue. These results suggest that the position of double bonds in dietary fatty acids, as well as the quantity of dietary fat, may have a significant effect on the regulation of oxidative and thermogenic conditions in vivo. PMID- 29473918 TI - Metal Nanoparticles/Porous Silicon Microcavity Enhanced Surface Plasmon Resonance Fluorescence for the Detection of DNA. AB - A porous silicon microcavity (PSiMC) with resonant peak wavelength of 635 nm was fabricated by electrochemical etching. Metal nanoparticles (NPs)/PSiMC enhanced fluorescence substrates were prepared by the electrostatic adherence of Au NPs that were distributed in PSiMC. The Au NPs/PSiMC device was used to characterize the target DNA immobilization and hybridization with its complementary DNA sequences marked with Rhodamine red (RRA). Fluorescence enhancement was observed on the Au NPs/PSiMC device substrate; and the minimum detection concentration of DNA ran up to 10 pM. The surface plasmon resonance (SPR) of the MC substrate; which is so well-positioned to improve fluorescence enhancement rather the fluorescence enhancement of the high reflection band of the Bragg reflector; would welcome such a highly sensitive in biosensor. PMID- 29473919 TI - Leader-Follower Formation Control of UUVs with Model Uncertainties, Current Disturbances, and Unstable Communication. AB - Unmanned underwater vehicles (UUVs) have rapidly developed as mobile sensor networks recently in the investigation, survey, and exploration of the underwater environment. The goal of this paper is to develop a practical and efficient formation control method to improve work efficiency of multi-UUV sensor networks. Distributed leader-follower formation controllers are designed based on a state feedback and consensus algorithm. Considering that each vehicle is subject to model uncertainties and current disturbances, a second-order integral UUV model with a nonlinear function is established using the state feedback linearized method under current disturbances. For unstable communication among UUVs, communication failure and acoustic link noise interference are considered. Two layer random switching communication topologies are proposed to solve the problem of communication failure. For acoustic link noise interference, accurate representation of valid communication information and noise stripping when designing controllers is necessary. Effective communication topology weights are designed to represent the validity of communication information interfered by noise. Utilizing state feedback and noise stripping, sufficient conditions for design formation controllers are proposed to ensure UUV formation achieves consensus under model uncertainties, current disturbances, and unstable communication. The stability of formation controllers is proven by the Lyapunov Razumikhin theorem, and the validity is verified by simulation results. PMID- 29473915 TI - Infection and Transport of Herpes Simplex Virus Type 1 in Neurons: Role of the Cytoskeleton. AB - Herpes simplex virus type 1 (HSV-1) is a neuroinvasive human pathogen that has the ability to infect and replicate within epithelial cells and neurons and establish a life-long latent infection in sensory neurons. HSV-1 depends on the host cellular cytoskeleton for entry, replication, and exit. Therefore, HSV-1 has adapted mechanisms to promote its survival by exploiting the microtubule and actin cytoskeletons to direct its active transport, infection, and spread between neurons and epithelial cells during primary and recurrent infections. This review will focus on the currently known mechanisms utilized by HSV-1 to harness the neuronal cytoskeleton, molecular motors, and the secretory and exocytic pathways for efficient virus entry, axonal transport, replication, assembly, and exit from the distinct functional compartments (cell body and axon) of the highly polarized sensory neurons. PMID- 29473921 TI - Concurrent presence of on- and off-pathway folding intermediates of apoflavodoxin at physiological ionic strength. AB - Flavodoxins have a protein topology that can be traced back to the universal ancestor of the three kingdoms of life. Proteins with this type of architecture tend to temporarily misfold during unassisted folding to their native state and form intermediates. Several of these intermediate species are molten globules (MGs), which are characterized by a substantial amount of secondary structure, yet without the tertiary side-chain packing of natively folded proteins. An off pathway MG is formed at physiological ionic strength in the case of the F44Y variant of Azotobacter vinelandii apoflavodoxin (i.e., flavodoxin without flavin mononucleotide (FMN)). Here, we show that at this condition actually two folding species of this apoprotein co-exist at equilibrium. These species were detected by using a combination of FMN fluorescence quenching upon cofactor binding to the apoprotein and of polarized time-resolved tryptophan fluorescence spectroscopy. Besides the off-pathway MG, we observe the simultaneous presence of an on-pathway folding intermediate, which is native-like. Presence of concurrent intermediates at physiological ionic strength enables future exploration of how aspects of the cellular environment, like for example involvement of chaperones, affect these species. PMID- 29473920 TI - Prevalence and associations of presenting near-vision impairment in the Australian National Eye Health Survey. AB - PurposeTo describe the prevalence and associations of presenting near vision impairment (NVI) in Indigenous and non-Indigenous Australians.MethodsA sample of 3098 non-Indigenous Australians (aged 50-98 years) and 1738 Indigenous Australians (aged 40-92 years) living in 30 randomly selected Australian sites were examined as part of the population-based National Eye Health Survey (NEHS). Binocular presenting NVI was defined as near vision worse than N8 (20/50).ResultsIn total, 4817 participants (99.6% of the total sample, comprising 3084 non-Indigenous Australians and 1733 Indigenous Australians) had complete data on near visual acuity. The overall weighted prevalence of presenting NVI was 21.6% (95% CI: 19.6, 23.8) in non-Indigenous Australians and 34.7% (95% CI: 29.2, 40.8) among Indigenous Australians. In the non-Indigenous population, higher odds of presenting NVI were associated with older age (OR=1.68 per 10 years, P<0.001), fewer years of education (OR=0.95 per year, P<0.001) and residing in Remote geographical areas (OR=1.71, P=0.003) after multivariate adjustments. Among Indigenous Australians, older age (OR=1.69 per 10 years, P<0.001), fewer years of education (OR=0.91 per year, P=0.003) and residing in Inner Regional (OR=2.01, P=0.008), Outer Regional (OR=2.17, P=<0.001) and Remote geographical areas (OR=1.72, P=0.03) were associated with greater odds of presenting NVI.ConclusionsNVI represents a notable public health concern in Australia, affecting approximately 20% of non-Indigenous Australian and one-third of Indigenous Australian adults. PMID- 29473922 TI - Kinetics of the reaction of CO3-(H2O)n, n = 0, 1, 2, with nitric acid, a key reaction in tropospheric negative ion chemistry. AB - A significant fraction of nitrate in the troposphere is formed in the reactions of HNO3 with the carbonate radical anion CO3- and the mono- and dihydrated species CO3-(H2O)1,2. A reaction mechanism was proposed in earlier flow reactor studies, which is investigated here in more detail by quantum chemical calculations and experimental reactivity studies of mass selected ions under ultra-high vacuum conditions. Bare CO3- forms NO3-(OH) as well as NO3-, with a total rate coefficient of 1.0 * 10-10 cm3 s-1. CO3-(H2O) in addition affords stabilization of the NO3-(HCO3) collision complex, and thermalized CO3-(H2O) reacts with a total rate coefficient of 6.3 * 10-10 cm3 s-1. A second solvent molecule quenches the reaction, and only black-body radiation induced dissociation is observed for CO3-(H2O)2, with an upper limit of 6.0 * 10-11 cm3 s 1 for any potential bimolecular reaction channel. The rate coefficients obtained under ultra-high vacuum conditions are smaller than in the earlier flow reactor studies, due to the absence of stabilizing collisions, which also has a strong effect on the product branching ratio. Quantum chemical calculations corroborate the mechanism proposed by Mohler and Arnold. The reaction proceeds through a proton-transferred NO3-(HCO3) collision complex, which can rearrange to NO3 (OH)(CO2). The weakly bound CO2 easily evaporates, followed by evaporation of the more strongly attached OH, if sufficient energy is available. PMID- 29473923 TI - Sum-frequency vibrational spectroscopy of limonene chiral liquids due to the nonadiabatic effect. AB - Using quantum computations we study sum-frequency vibrational spectroscopy of limonene chiral liquids due to the nonadiabatic effect in the non-resonant case for the first time. The nonadiabatic effect has an important impact on non resonant antisymmetric polarizability and chiral sum-frequency vibrational spectroscopy. The theoretical spectroscopy agrees with the experimental spectroscopy. However, the nonadiabatic effect only has a small influence on non resonant Raman. Bulk sum-frequency vibrational spectroscopy may become a powerful method of investigating the nonadiabatic effect and the nonradiative transition between excited electronic states for chiral molecules. PMID- 29473924 TI - Selective interface transparency in graphene nanoribbon based molecular junctions. AB - A clear understanding of electrode-molecule interfaces is a prerequisite for the rational engineering of future generations of nanodevices that will rely on single-molecule coupling between components. With a model system, we reveal a peculiar dependence on interfaces in all graphene nanoribbon-based carbon molecular junctions. The effect can be classified into two types depending on the intrinsic feature of the embedded core graphene nanoflake (GNF). For metallic GNFs with |NA - NB| = 1, good/poor contact transparency occurs when the core device aligns with the center/edge of the electrode. The situation is reversed when a semiconducting GNF is the device, where NA = NB. These results may shed light on the design of real connecting components in graphene-based nanocircuits. PMID- 29473925 TI - Rational design of 3D inverse opal heterogeneous composite microspheres as excellent visible-light-induced NO2 sensors at room temperature. AB - The lower gas sensitivity, humidity dependence of the gas sensing properties, and long recovery times of room-temperature gas sensors severely limit their applications. Herein, to address these issues, a series of 3D inverse opal (IO) In2O3-ZnO heterogeneous composite microspheres (HCMs) are fabricated by ultrasonic spray pyrolysis (USP) employing self-assembled sulfonated polystyrene (S-PS) spheres as a sacrificial template. The 3D IO In2O3-ZnO HCMs possess highly ordered 3D inverse opal structures and bimodal (meso-scale and macro-scale) pores, which can provide large accessible surface areas and rapid mass transfer, resulting in enhanced gas sensing characteristics. Furthermore, the 3D IO architecture and n-n heterojunctions can extend the photoabsorption range to the visible light area, effectively prolonging the lifetimes of photo-generated charge carriers, and can increase separation of visible light-generated charges. As a result, the as-prepared 3D IO In2O3-ZnO HCMs deliver excellent NO2 sensing performance under visible light irradiation at room temperature, such as high sensitivity (Rgas/Rair = 54.3 to 5 ppm NO2), low detection limit (250 ppb), fast recovery time (188 s), excellent selectivity and humidity independence. These enhanced photo-electronic gas sensing properties are attributed to the combination of highly ordered 3D IO microspheres and In2O3-ZnO heterogeneous composites.

AB - Here, we report that a reduction in scale leads to an enhancement in the photoluminescence (PL) of Eu3+ doped BiOCl nanosheets, challenging the long standing notion that PL is inevitably suppressed at a scale of tens of nanometers. The oriented depolarization effect of layered ferroelectrics was utilized for the first time to improve the PL efficiency of lanthanide doped nanomaterials. The probing effect of the electric dipole transitions of the Eu3+ ions and their PL measurements provides evidence that the depolarization field and the PL of Eu3+ ions increase synchronously as the thickness of the BiOCl single-crystalline nanosheets decreases from hundreds to tens of nanometers. We show that the scale-dependent internal electric field (IEF) induced by the depolarization field as well as its excitation field enhancement are responsible for the appearance of an abnormal scale-dependent PL enhancement. This finding may be useful for the development of low-dimensional material systems with enhanced photophysical properties, relevant for use in new nano-optoelectronic devices. PMID- 29473927 TI - Screening and identification of inhibitors of advanced glycation endproduct formation from microalgal extracts. AB - The formation and accumulation of advanced glycation endproducts (AGEs) have been implicated in the pathogenesis of many chronic diseases, such as aging, Alzheimer's disease, diabetes and diabetic complications. The present study was aimed to investigate the inhibitory effects of the extracts from nine microalgae on the formation of AGEs by using in vitro models and identify key antiglycation constituents of the microalgae. A BSA-glucose model with simulated physiological conditions was used to evaluate the inhibitory effect on total AGE formation. A BSA-MGO model was used to study the inhibitory activity against the dicarbonyl induced AGE formation. The results showed that the aqueous acetone extracts exhibited stronger antiglycation activity than the other extracts (ethyl acetate and dichloromethane) and that the marine microalgal extracts were generally more effective than the freshwater ones. Their inhibitory rates ranged from >60% to 90% when used at a concentration of 0.5 mg mL-1. HPLC-DAD and UPLC-Q-TOF-MSE analyses revealed that fucoxanthin was likely the principal component which contributed to the observed antiglycation activity. Further analysis established a highly significant positive correlation (R2 > 0.95) between the fucoxanthin content and the antiglycation activity of the aqueous acetone extracts. This is the first report on the antiglycation activity of fucoxanthin. The findings of the present study have not only identified a promising inhibitor of AGE formation, but have also identified a valuable natural source of this phytochemical which possesses great potential to be developed as functional food ingredients and pharmaceutical products to help reduce health risks associated with AGEs.

AB - Herein, a novel non-platinum core-shell catalyst, namely, IrNi@PdIr/C was prepared via a galvanic replacement reaction; it exhibits enhanced hydrogen oxidation activity and excellent stability under alkaline conditions. Electrochemical experiments demonstrated that the mass and specific activities at 50 mV of IrNi@PdIr/C are 2.1 and 2.2 times that of commercial Pt/C in 0.1 M KOH at 298 K, respectively. Moreover, accelerated degradation tests have shown that the electrochemically active surface area (ECSA) of IrNi@PdIr/C reduces by only 5.1%, which is almost 4 times less than that of commercial Pt/C and the mass activity at 50 mV of IrNi@PdIr/C after 2000 potential cycles is still 1.8 times higher than that of aged Pt/C. XRD and XPS analysis suggest that the enhanced HOR activity is attributed to the weakening of the hydrogen binding to the PdIr overlayers induced by the IrNi core. The better stability to potential cycling can be associated with the PdIr shell, which inhibits oxide formation. These results suggest that IrNi@PdIr/C is a promising non-platinum anode catalyst for alkaline anion exchange membrane fuel cells.

AB - A collaborative strategy is developed for constructing stable lithium metal anodes by using self-supporting three-dimensional nitrogen-doped graphene foams as the multifunctional host matrix. The resultant electrode shows impressive electrochemical performances, attributable to the three-dimensional porous architecture and nitrogen-doping nature of such a unique host matrix.

AB - Functional nanocomposite coatings comprised of periodically stacked nanolayers of diamond-like carbon (DLC) and amorphous silicon were developed for biomedical applications. The periodical nanocomposite structure provided high surface durability while silicon aided in reducing the residual stress. The structural, mechanical, tribological, and biomedical properties of the Si/DLC coatings deposited by magnetron sputtering were investigated systematically. The effect of the negative substrate bias on the structure and properties of the coatings was also assessed. The coatings demonstrated high durability and high biocompatibility. The bias voltage and bias mode affected both the hardness and residual stress of the Si/DLC coatings. Particularly, application of 60 V negative bias during the DLC layer deposition resulted in the lowest wear rate. FEM simulations showed that the wear resistance of the coatings was dictated by the hardness as well as the adhesion between the coatings and a chromium sub layer. The periodical alternation of Si and DLC nanolayers led to a significant improvement of MC3T3 cell adhesion compared to the previously published data for Si-DLC composites.

AB - An extensive karyotype variation is found among species belonging to the Columbidae family of birds (Columbiformes), both in diploid number and chromosomal morphology. Although clusters of repetitive DNA sequences play an important role in chromosomal instability, and therefore in chromosomal rearrangements, little is known about their distribution and amount in avian genomes. The aim of this study was to analyze the distribution of 11 distinct microsatellite sequences, as well as clusters of 18S rDNA, in nine different Columbidae species, correlating their distribution with the occurrence of chromosomal rearrangements. We found 2n values ranging from 76 to 86 and nine out of 11 microsatellite sequences showed distinct hybridization signals among the analyzed species. The accumulation of microsatellite repeats was found preferentially in the centromeric region of macro and microchromosomes, and in the W chromosome. Additionally, pair 2 showed the accumulation of several microsatellites in different combinations and locations in the distinct species, suggesting the occurrence of intrachromosomal rearrangements, as well as a possible fission of this pair in Geotrygon species. Therefore, although birds have a smaller amount of repetitive sequences when compared to other Tetrapoda, these seem to play an important role in the karyotype evolution of these species. PMID- 29473934 TI - Absence of TERT promoter mutations in colorectal precursor lesions and cancer. AB - Hotspot mutations (c.-124bp G > A and c.-146bp G > A) in the promoter region of the TERT gene have been recently described in several types of solid tumors, including glioma, bladder, thyroid, liver and skin neoplasms. However, knowledge with respect to colorectal precursor lesions and cancer is scarce. In the present study we aimed to determine the frequency of hotspot TERT promoter mutations in 145 Brazilian patients, including 103 subjects with precursor lesions and 42 with colorectal carcinomas, and we associated the presence of such mutations with the patients clinical-pathological features. The mutation analysis was conclusive in 123 cases, and none of the precursor and colorectal carcinoma cases showed TERT promoter mutations. We conclude that TERT mutations are not a driving factor in colorectal carcinogenesis. PMID- 29473933 TI - Assessment of genetic integrity, splenic phagocytosis and cell death potential of (Z)-4-((1,5-dimethyl-3-oxo-2-phenyl-2,3dihydro-1H-pyrazol-4-yl) amino)-4-oxobut-2 enoic acid and its effect when combined with commercial chemotherapeutics. AB - The increased incidence of cancer and its high treatment costs have encouraged the search for new compounds to be used in adjuvant therapies for this disease. This study discloses the synthesis of (Z)-4-((1,5-dimethyl-3-oxo-2-phenyl 2,3dihydro-1H-pyrazol-4-yl) amino)-4-oxobut-2-enoic acid (IR-01) and evaluates not only the action of this compound on genetic integrity, increase in splenic phagocytosis and induction of cell death but also its effects in combination with the commercial chemotherapeutic agents doxorubicin, cisplatin and cyclophosphamide. IR-01 was designed and synthesized based on two multifunctionalyzed structural fragments: 4-aminoantipyrine, an active dipyrone metabolite, described as an antioxidant and anti-inflammatory agent; and the pharmacophore fragment 1,4-dioxo-2-butenyl, a cytotoxic agent. The results indicated that IR-01 is an effective chemoprotector because it can prevent clastogenic and/or aneugenic damage, has good potential to prevent genomic damage, can increase splenic phagocytosis and lymphocyte frequency and induces cell death. However, its use as an adjuvant in combination with chemotherapy is discouraged since IR-01 interferes in the effectiveness of the tested chemotherapeutic agents. This is a pioneer study as it demonstrates the chemopreventive effects of IR-01, which may be associated with the higher antioxidant activity of the precursor structure of 4-aminoantipyrine over the effects of the 1,4-dioxo-2-butenyl fragment. PMID- 29473936 TI - Differential survivorship of congeneric ornamental fishes under forecasted climate changes are related to anaerobic potential. AB - Two Amazonian closely related tetras - cardinal Paracheirodon axelrodi and green neon P. simulans - were artificially acclimatized to environmental chambers mimicking future climate change scenarios (mild, moderate and extreme), using a microcosm facility. P. simulans survived (100%) to all scenarios after 30 days exposure, while P. axelrodi presented decreasing survival percentages according to environmental severity. These differences may be the reflection of distinct natural acclimatization to microhabitats between the species, which differ in thermal conditions. Survival responses might be related to differences in relative gene expression of lactate dehydrogenase (Ldh), suggesting that P. axelrodi anaerobic potential is lower or non-existent compared to P. simulans, not tolerating long-term thermal challenges. Accordingly, increases in temperature and in CO2 levels caused increases in energy demand and resulted in activation of the anaerobic pathway, as demonstrated by the higher enzyme levels measured in head and tail portions of both species. Sustained anaerobic glycolysis is possible when fish live in challenging environments (low oxygen or high temperature). Our results clearly show that P. simulans has a larger scope for survival to higher energy demands due to its increased anaerobic potential compared to P. axelrodi. PMID- 29473935 TI - Dyslexia risk variant rs600753 is linked with dyslexia-specific differential allelic expression of DYX1C1. AB - An increasing number of genetic variants involved in dyslexia development were discovered during the last years, yet little is known about the molecular functional mechanisms of these SNPs. In this study we investigated whether dyslexia candidate SNPs have a direct, disease-specific effect on local expression levels of the assumed target gene by using a differential allelic expression assay. In total, 12 SNPs previously associated with dyslexia and related phenotypes were suitable for analysis. Transcripts corresponding to four SNPs were sufficiently expressed in 28 cell lines originating from controls and a family affected by dyslexia. We observed a significant effect of rs600753 on expression levels of DYX1C1 in forward and reverse sequencing approaches. The expression level of the rs600753 risk allele was increased in the respective seven cell lines from members of the dyslexia family which might be due to a disturbed transcription factor binding sites. When considering our results in the context of neuroanatomical dyslexia-specific findings, we speculate that this mechanism may be part of the pathomechanisms underlying the dyslexia-specific brain phenotype. Our results suggest that allele-specific DYX1C1 expression levels depend on genetic variants of rs600753 and contribute to dyslexia. However, these results are preliminary and need replication. PMID- 29473937 TI - Large deletion in PIGL: a common mutational mechanism in CHIME syndrome? AB - CHIME syndrome is an extremely rare autosomal recessive multisystemic disorder caused by mutations in PIGL. PIGL is an endoplasmic reticulum localized enzyme that catalyzes the second step of glycosylphosphatidylinositol (GPI) biosynthesis, which plays a role in the anchorage of cell-surface proteins including receptors, enzymes, and adhesion molecules. Germline mutations in other members of GPI and Post GPI Attachment to Proteins (PGAP) family genes have been described and constitute a group of diseases within the congenital disorders of glycosylation. Patients in this group often present alkaline phosphatase serum levels abnormalities and neurological symptoms. We report a CHIME syndrome patient who harbors a missense mutation c.500T > C (p.Leu167Pro) and a large deletion involving the 5' untranslated region and part of exon 1 of PIGL. In CHIME syndrome, a recurrent missense mutation c.500T > C (p.Leu167Pro) is found in the majority of patients, associated with a null mutation in the other allele, including an overrepresentation of large deletions. The latter are not detected by the standard analysis in sequencing techniques, including next-generation sequencing. Thus, in individuals with a clinical diagnosis of CHIME syndrome in which only one mutation is found, an active search for a large deletion should be sought. PMID- 29473938 TI - Shared decision-making for prostate cancer screening and treatment: a systematic review of randomised controlled trials. AB - INTRODUCTION: Men facing prostate cancer screening and treatment need to make critical and highly preference-sensitive decisions that involve a variety of potential benefits and risks. Shared decision-making (SDM) is considered fundamental for "preference-sensitive" medical decisions and it is guideline recommended. There is no single definition of SDM however. We systematically reviewed the extent of SDM implementation in interventions to facilitate SDM for prostate cancer screening and treatment. METHODS: We searched Medline Ovid, Embase (Elsevier), CINHAL (EBSCOHost), The Cochrane Library (Wiley), PsychINFO (EBSCOHost), Scopus, clinicaltrials.gov, ISRCTN registry, the WHO search portal, ohri.ca, opengrey.eu, Google Scholar, and the reference lists of included studies, clinical guidelines and relevant reviews. We also contacted the authors of relevant abstracts without available full text. We included primary peer reviewed and grey literature of randomised controlled trials (RCTs) reported in English, conducted in primary and specialised care, addressing interventions aiming to facilitate SDM for prostate cancer screening and treatment. Two reviewers independently selected studies, appraised interventions and assessed the extent of SDM implementation based on the key features of SDM, namely information exchange, deliberation and implementation. We considered bi directional deliberation as a central and mandatory component of SDM. We performed a narrative synthesis. RESULTS: Thirty-six RCTs including 19 196 randomised patients met the eligibility criteria; they were mainly conducted in North America (n = 28). The median year of publication was 2008 (1997-2015). Twenty-three RCTs addressed decision-making for screening, twelve for treatment and one for both screening and treatment for prostate cancer. Bi-directional interactions between healthcare providers and patients were verified in 31 RCTs, but only 14 fulfilled the three key SDM features, 14 had at least "deliberation", one had "unclear deliberation" and two had no signs of deliberation. CONCLUSIONS: There is significant variation in the extent of SDM implementation among studies addressing SDM for prostate cancer screening and treatment. Further evaluation of these results on patient outcomes, a standardised SDM definition and guidance for an effective implementation in several clinical settings are needed.
